BACKGROUND: Cardiovascular disease (CVD) is a leading contributor to morbidity and mortality among people living with cancer. In sub-Saharan Africa, due to the overall cost of the treatment, resource limitations, and a lack of specialized cardio-oncologists, cardio-oncology care is limited. As such, access to advanced cardiac imaging and biomarkers is often limited, making the 12-lead electrocardiogram (ECG) a pragmatic tool for early detection of chemotherapy-associated electrophysiological abnormalities. We investigated early ECG abnormalities following chemotherapy in an African cohort. METHODS: We conducted a five-month prospective cohort study at the Douala General Hospital, Cameroon. Adults (≥ 19 years) with cancer initiating first-ever chemotherapy were enrolled. A 12-lead ECG was obtained at baseline (pre-chemotherapy) and 48 h after each chemotherapy cycle. A “new ECG abnormality” was defined as an abnormality present post-cycle that was absent at baseline. We described the frequency and types of ECG abnormalities and examined factors associated with a new ECG abnormality after cycle 1 using multivariable logistic regression. RESULTS: A total of 102 participants (74 women, 72.5%) were included; mean age was 48.7 ± 13.5 years. At baseline, 71/102 participants (69.6%) had a normal ECG. During follow-up, 53/102 participants (51.9%) had at least one ECG abnormality after chemotherapy. The most frequent abnormalities were prolonged corrected QT interval 19/53 (35.8%), T-wave/repolarisation abnormalities 17/53 (32.0%), and sinus bradycardia or tachycardia 10/53 (18.8%). Atrial fibrillation occurred in 2/53 participants (3.7%). In univariable analysis, hypertension was associated with ECG abnormalities after chemotherapy (OR 4.03, 95% CI 1.22–13.28). In the cycle 1 multivariable model, no covariate was statistically significantly associated with a new ECG abnormality; hypertension showed a positive but non-significant association (aOR 2.96, 95% CI 0.79–11.03. CONCLUSION: We found that ECG abnormalities were common after chemotherapy in this Cameroonian cohort, with QT prolongation and repolarisation changes most frequently observed. Hypertension showed a positive association with new ECG abnormalities after the first chemotherapy cycle. In resource-constrained settings, baseline ECG and early post-cycle ECG surveillance may support detection of potentially clinically relevant electrical disturbances. While this study suggests ECG changes were common, these ECG findings should not be interpreted as synonymous with cardiotoxicity, but should be corroborated with imaging and biomarkers. Larger studies with cycle-level follow-up are needed to clarify predictors and prognostic implications of early ECG changes.

Integrase mutations associated with dolutegravir resistance have been well characterized, but based on limited data from non-B subtypes. We aim to identify potential integrase mutations not currently classified as integrase strand transfer inhibitor (INSTI) resistance mutations (DRMs) in individuals with viremia on dolutegravir-based regimens. We included integrase sequences from DTG RESIST study sites in African countries. These were interpreted using Stanford HIVdb v9.8. We used a viral genome-wide association study-like approach restricted to the integrase region (INT-WAS) to identify mutations not classified as major or accessory INSTI DRMs but occurring more frequently in sequences carrying major INSTI DRMs than in those without major INSTI DRMs. We performed the same INT-WAS analysis with drug-naïve sequences from the Los Alamos HIV-1 database to test whether these identified mutations were enriched among sequences from individuals with viraemia whilst receiving DTG-based treatment. Among 382 sequences, 104 (27.2%) showed at least intermediate dolutegravir resistance. Twelve integrase mutations not classified as major or accessory DRMs (S39R, L45I, I72L, L74I, V79I, I113V, S119R, K156N, I208M, T218M, A265V, and R284G) were significantly associated with predicted DTG resistance. Among them, V79I [adjusted odds ratio (aOR) 167.1, 95% credible interval (CrI) 17.9-2947.6] and I72L (aOR 65.6, 95% CrI 6.6-1273.7) were strongly associated. S39R, L45I, V79I, S119R, and K156N were linked to established INSTI resistance pathways, and I72L, L74I, V79I, K156N, I208M, and R284G were overrepresented in sequences from viraemic individuals on DTG-based treatment relative to drug-naïve sequences. We identified several amino acid substitutions outside the established DRMs that are strongly associated with predicted dolutegravir resistance. Dolutegravir resistance evolution is complex and likely involves mutations not currently classified as DRMs.

The COVID-19 pandemic was a global public concern and constitutes a future threat to the world population due to its indirect effect on the burden of non-communicable diseases. The pandemic manifested disruptions in healthcare delivery and access. However, there is limited data in Sub-Saharan Africa on the impact of COVID-19 on cardiovascular disease (CVD) admissions and outcomes. This study aimed to compare the trends of CVD admissions and outcomes before and during the COVID-19 pandemic in the Southwest Region of Cameroon. We carried out a retrospective study of patients suffering from CVDs admitted from March 11, 2018, to March 11, 2020 (Pre-COVID-19 pandemic period) and from March 11, 2020, to March 11, 2022 (COVID-19 pandemic period). A -value < 0.05 was considered statistically significant. There were 483 admissions due to CVD during the COVID-19 pandemic and 518 during the pre-COVID-19 period. There was no significant difference in mean age before (57.97 ± 15.6 years) and during the pandemic (59.74 ± 16.1 years) ( = 0.44). There was also no significant change in the proportion of males and females during and before the pandemic: males (21, 4%, and 24.8%), and females (26.8% and 27%), ( = 0.28). There was a downward secular trend with random variation in the number of CVD admissions during the pandemic compared with the corresponding pre-COVID period, which had an upward trend. Rates of admissions of Acute Myocardial Infarction decreased the most (22.2%) during the first wave of the pandemic. The in-hospital mortality increased by 2.4% with a relative risk for Mortality of 1.18 (95% CI [0.87-1.61],  = 0.28). There was no change in median length of hospital stay ( = 0.936). This study provides evidence of a decreasing tendency in admissions due to CVD during the COVID-19 Pandemic at the BRH. The effects varied among the different types of CVDs. The in-hospital mortality of CVDs did not change significantly.

Thoughts of death or self-injury and the clinical implications of such thoughts remain largely underassessed among people with HIV (PWH) in Africa. As strong predictors of suicidal ideation and death by suicide, it is paramount to understand these risk indicators, particularly in populations with heightened susceptibility to poor mental health. We aimed to characterize thoughts of death or self-injury (i.e., self-injurious thoughts) and their relationship with non-same-day (i.e., delayed) anti-retroviral treatment (ART) initiation and longitudinal disengagement from clinic in a cohort of PWH newly entering HIV care in Cameroon. We conducted structured interviews with PWH aged 21 + initiating clinical care between June 2019 and March 2020. Clinical records were used to ascertain ART initiation date and disengagement from the clinic across two years following care initiation. Log binomial regression was used to estimate the association between self-injurious thoughts at care initiation and delayed ART initiation. A Fine and Gray sub-distribution proportional hazards model was used to quantify the cumulative incidence of disengagement from the clinic (i.e., a gap in clinic visits > 183 days) and differences in these estimates across groups. Of 426 enrolled individuals, seventy-one (16.7%) endorsed self-injurious thoughts at entry into care, 24 (33.8%) of whom had active thoughts of self-injury. Self-injurious thoughts at entry into care were positively associated with delayed ART initiation (adjusted prevalence ratio = 1.8; 95% CI: 1.2, 2.9) and cumulative incidence of disengagement from clinic, though differences in disengagement were statistically non-significant. Interventions are urgently needed to support the mental health and well-being of PWH entering care and improve down-stream HIV treatment outcomes.

Our recent estimate of the global 1-year prevalence of headache among those aged 18-65 years was 65%: considerably higher than previous estimates, but based solely on high-quality epidemiological data derived from a large population-based sample. Here we present complementary estimates of 1-day prevalence. We performed a meta-analysis of individual participant data from cross-sectional surveys among population-representative samples (age range 18-65 years) from 15 countries and all world regions. All used the Headache-Attributed Restriction, Disability, Social Handicap and Impaired Participation (HARDSHIP) questionnaire, including the question "did you have a headache yesterday?", from which 1-day prevalence was determined. An algorithmic process applying modified ICHD criteria yielded separate estimates for migraine, tension-type headache (TTH) and probable medication-overuse headache (pMOH: the association of headache on ≥ 15 days/month and medication overuse). We analysed associations with age, gender and country-income level, and adjusted prevalence estimates for these factors. We calculated predicted 1-day prevalence from 1-year prevalence and reported headache frequency. Among the 38,512 participants, females (53.4%) and participants from low- (17.1%) or lower-middle-income countries (64.6%) were overrepresented, but age distribution fairly matched that of the world. Overall, 13.7% (95% CI: 13.3-14.0) reported headache yesterday, females (17.1% [16.6-17.6]) more than males (9.7% [9.3-10.2]). Migraine was the most common headache type yesterday (6.0% [5.8-6.3]), followed by TTH (4.1% [3.9-4.3]) and pMOH (2.3% [2.2-2.5]). One-day headache prevalence was higher in low/lower-middle-income countries (13.9% [13.6-14.3]) than in high/upper-middle-income countries (12.4% [11.6-13.2]). Predicted 1-day prevalence (10.9% [10.7-11.1]) was considerably lower than observed 1-day prevalence (13.7% [13.3-14.0]), although not among those with pMOH (3.1% [3.0-3.3] versus 2.3% [2.2-2.5]). Adjusted for age, gender and country-income level, global 1-day prevalence estimates were 13.1% (12.8-13.5) for any headache, 5.7% (5.5-5.9) for migraine, 3.9% (3.7-4.1) for TTH and 2.4% (2.3-2.6) for pMOH, with 1.0% undiagnosed. Assuming yesterday was no different from any other day, an estimated 13.1% (N = 641,900,000) of the world's population aged 18-65 years will have headache tomorrow; almost half will be migraine. People with migraine or TTH underestimate the frequency of headache episodes. Since headache-attributed burden is usually estimated from recalled frequency over 1-12 months, this also may be underestimated.

The burden of cardiometabolic diseases (CMDs) is rising in people with HIV (PWH). While extensive data exist on CMD prevalence in PWH receiving antiretroviral therapy (ART), comprehensive data on ART-naïve PWH are scarce. We aimed to estimate the global prevalence of hypertension, diabetes, obesity and dyslipidaemia among ART-naïve PWH and compare estimates with those on ART and HIV-negative populations. This systematic review and meta-analysis included a search of PubMed-MEDLINE, CINAHL, SCOPUS, Academic Search Premier, Africa-Wide Information and Africa-Journals Online for original articles published up to June 2024. Cross-sectional, cohort and case-control studies providing baseline data on CMD prevalence were included. Studies had to include ART-naïve PWH aged ≥15 years. Two independent reviewers conducted studies screening, data extraction and methodological quality assessment. A random-effects meta-analysis with double arc-sine transformation was used for prevalence estimates. The study was registered with PROSPERO (CRD42021226001). We included 184 studies published between 2000 and 2024, involving a total of 424 629 participants. The global pooled prevalence among ART-naïve PWH was 14.2% (95% CI: 12.4-16.1) for hypertension, 3.6% (2.9-4.3) for diabetes, 11.5% (10.3-12.9) for body mass index-based obesity, 18.3% (12.7-24.6) for waist circumference-based obesity, 14.8% (12.1-17.8) for elevated total cholesterol, 17.6% (11.3-24.8) for elevated low-density lipoprotein cholesterol, 22.9% (19.3-26.7) for elevated triglycerides and 54.6% (48.2-61.0) for low high-density lipoprotein cholesterol, all with high heterogeneity. Significant regional variations in the prevalence of diabetes, obesity and dyslipidaemia were observed according to UNAIDS regions. We found a notable prevalence of CMDs in ART-naïve PWH, with significant regional variations in the prevalence of diabetes, obesity and dyslipidaemia. This highlights the need for targeted interventions and early screening to address the growing CMD burden among PWH. ART-naïve PWH face a considerable CMD burden, emphasizing the importance of early detection and management. Regional differences in CMD prevalence call for tailored public health strategies and integration of CMD prevention into HIV care protocols.

Prevention, screening and diagnostic services for hepatitis B virus (HBV) and hepatitis C virus (HCV) can prevent morbidity and mortality in people receiving HIV care. However, there is limited information about the availability of HBV and HCV services at HIV clinics globally. The International epidemiology Databases to Evaluate AIDS (IeDEA) conducted surveys of service delivery and practices at participating HIV treatment centers from seven regions. We used 2023 survey data to measure availability of HBV vaccination, HBV and HCV screening, HBV surface antigen (HBsAg), HBV DNA, HCV antibody, HCV RNA testing. Multivariable logistic regression models were used to test associations of site characteristics with HBV and HCV services. HBV vaccination was available on-site at 67.7% of 204 HIV treatment sites. Screening for HBV and HCV at HIV care enrollment was reported by 72.1% and 50% of sites, respectively. HBsAg, HBV DNA, HCV antibody and HCV RNA testing were available on-site at 77%, 47.6%, 61.8% and 44.6% of sites, respectively. Sites serving predominately rural (vs. urban) populations were less likely to report on-site availability of HBV DNA (odds ratio (OR):0.07; 95% confidence interval (CI):0.01-0.68;P=0.02), HCV antibody (OR=0.18; 95% CI:0.04-0.92;P=0.04) and HCV RNA (OR=0.10; 95% CI:0.01-0.90;P=0.04) testing. Life-saving services such as HBV vaccination, HBsAg and HCV antibody testing were available on-site at most HIV treatment sites participating in the IeDEA network. Lower availability at rural sites suggests that expansion of services is important to eliminate HBV and HCV as public health problems in people receiving HIV care.

Nonadherence to blood pressure (BP)-lowering medication is a strong predictor of poor BP control. Sub-Saharan Africa has extremely low BP control rates (~10%), but it is unclear what the burden of medication nonadherence among Africans with hypertension is. This systematic review estimated the prevalence and determinants of nonadherence to BP-lowering medications in Sub-Saharan Africa. Multiple databases were searched from inception to December 6, 2023. Two reviewers performed independent screening, extraction, and quality assessment of studies. We pooled the prevalence estimates using random effects meta-analyses and summarized the determinants using a narrative synthesis. From the 1307 records identified, we included 95 studies published between 1995 and 2023. The overall prevalence of nonadherence to BP-lowering medication among 34 102 people treated for hypertension in 27 countries was 43.9% (95% CI, 39.2-48.6). There was no change in the prevalence of nonadherence over time. Nonadherence varied by measurement method and by median age (39.4%, ≥57 years versus 47.9%, <57 years). Socioeconomic and patient-related factors were the most frequent factors influencing adherence. Active patient participation in management, accurate perceptions, and knowledge of hypertension and its treatment predicted good medication adherence, whereas high pill burden, medication cost, side effects, and comorbidities predicted poor adherence. Two out of every 5 people are nonadherent to their BP treatment. With the African population projected to increase from 1.4 to ~2.5 billion by 2050, targeted strategies are urgently needed to optimize medication adherence in people with hypertension in Sub-Saharan Africa.

Acute heart failure (AHF) remains a major global health challenge, contributing significantly to morbidity, mortality, and healthcare resource utilization. Among its clinical phenotypes, heart failure-related cardiogenic shock (HF-CS) represents a particularly severe and complex presentation that differs from acute myocardial infarction-related cardiogenic shock in terms of clinical characteristics, haemodynamic profiles, therapeutic response, and outcomes. In a subset of patients, AHF is related to or coexists with valvular heart diseases (VHDs) that require specific management strategies and treatments, namely aortic stenosis, mitral stenosis, aortic regurgitation, and mitral regurgitation. Another challenging scenario is represented by AHF in patients with end-stage renal disease (ESRD), since the risk of adverse outcomes is particularly high, conventional diuretic strategies cannot be pursued, and renal replacement therapy is frequently required. In this state-of-the-art review (part 4 of the International Expert Opinion Series on AHF Management), we propose a pragmatic, evidence-based framework for managing AHF complicated by HF-CS, VHDs, or ESRD.

Mediation analysis provides a more flexible mechanistic view of the causal relationship between HIV-related factors and cardiometabolic diseases. However, there is limited evidence on how mediation analysis is implemented in this specific research area. We aimed to describe the frameworks used in mediation analysis and examine how these analyses are conducted and reported in studies focusing on cardiometabolic outcomes among people living with HIV (PLWH). Following the PRISMA 2020 Guidelines, we comprehensively searched Medline, CINAHL, Africa-Wide Information and SCOPUS to identify observational studies that employed mediation analysis before October 2023. Two reviewers independently screened studies for eligibility. One reviewer performed data extraction, and two others reviewed the extracted information. Nine studies met the inclusion criteria, predominantly focusing on the mediation effects of weight and obesity-related factors on the relationship between HIV serostatus, ART, and cardiometabolic outcomes. The review revealed a diverse application of both traditional and causal mediation frameworks. However, inconsistencies and gaps in reporting were noted, particularly in handling missing data, detailing identifiability assumptions, and the use of sensitivity analyses. While some studies of cardiometabolic risks among PLWH have embraced causal mediation frameworks, their overall application remains limited. In addition, we identified notable inconsistencies and gaps in reporting practices. To advance the field, researchers should not only integrate more rigorous causal mediation methods but also closely follow established reporting guidelines, such as the AGReMA Statement, to ensure greater transparency, reliability, and impact of future research.

BackgroundIn Cameroon, people living with HIV (PLHIV) receiving antiretroviral therapy (ART) have a high prevalence of hypertension (HTN) and an increased risk of cardiovascular mortality. Managing HTN in this population is a major challenge. This qualitative study, conducted at the Yaoundé Central Hospital, Cameroon, in 2024, explored the barriers and facilitators to hypertension management in PLHIV.MethodsThe study involved 15 participants, including 9 PLHIV diagnosed with hypertension, 03 healthcare providers, and 03 psychosocial agents. A quota sampling approach was used to recruit participants. Data was collected through 12 in-depth interviews and a focus group with 3 psychosocial agents. Data collection took place over a period of 5 months, from January to May 2024. A semistructured interview guide was used to explore participants' perceptions of hypertension management. Data analysis was based on the COM-B model to interpret the results, using NVivo software.ResultsIdentified barriers included a lack of knowledge about hypertension, difficulties in accessing medications due to high costs, and psychosocial issues such as family stress affecting treatment adherence. Additionally, cultural and religious beliefs, such as a preference for traditional treatments and miraculous healings, limited engagement with conventional medicine. However, facilitators included regular visits for ART follow-up, which allowed for hypertension screening, and financial support from families that facilitated access to treatment. The proactive involvement of healthcare providers and continuous communication also contributed to treatment adherence.ConclusionThe study highlights the need for interventions that address socio-economic, cultural, and medical barriers to improve hypertension management in PLHIV, particularly through enhancing access to care and raising awareness.

Poor hypertension prevention among people living with HIV (PLHIV) in sub-Saharan Africa may undermine progress in HIV prevention achieved within this population. This review synthesizes data on the prevalence, diagnosis, treatment, control, and challenges related to hypertension prevention among PLHIV in SSA. A mixed-method systematic review with meta-analysis was conducted from January to December 2024. Data analysis was performed using random-effects modeling stratified by age and sex, along with thematic analysis. The JBI critical appraisal tool was used to assess study quality. A total of 31 studies, including 32286 PLHIV (±37 years old), were included. Hypertension affected 25% [95% CI, 21%-28%] of PLHIV, yet only 34% [95% CI, 11%-64%] of cases received treatment, and 19% [95% CI, 3%-34%] had controlled blood pressure, despite BP measurement in 95% [95% CI, 89%-100%] of them. Hypertension prevention challenges stem from patient-related factors, healthcare providers, and health system gaps. Despite the high prevalence of hypertension among PLHIV, treatment initiation and blood pressure control rates remain low. Strengthening the integration of HIV and hypertension care services is urgently needed.

BackgroundThe widespread use of antiretroviral therapy (ART) has significantly increased the life expectancy of people living with HIV (PLWHIV). However, this success is accompanied by a growing burden of non-communicable diseases, particularly hypertension, which has emerged as a leading contributor to morbidity and mortality in sub-Saharan Africa. Despite this growing concern, data on the burden and care cascade of hypertension among PLWHIV in routine care settings remain limited in Cameroon.ObjectiveTo assess the prevalence, associated factors, and care cascade of hypertension among PLWHIV receiving follow-up at Yaoundé Central Hospital in Cameroon in 2024.MethodsWe conducted a cross-sectional descriptive study at the Day Hospital of Yaounde Central Hospital, a national referral center for HIV care. PLWHIV aged ≥21 years and under active follow-up were included. Hypertension was defined as systolic and/or diastolic blood pressure ≥140/90 mm Hg or current use of antihypertensive medication. Logistic regression analyses were performed to identify factors associated with hypertension, including clinical and HIV-related parameters.ResultsA total of 554 participants were enrolled, of whom 74.0% were women, with a mean age of 50.9 years. The overall prevalence of hypertension was 36.8% (95% CI: 32.9-40.9) and was higher among men than women (45.1% vs 33.9%). Among hypertensive individuals (n = 204), 66.7% had initiated antihypertensive treatment, 45.6% were retained in care, and only 22.6% had controlled blood pressure. Factors independently associated with hypertension included longer ART duration (>16 years) (adjusted OR = 1.88;  = .036), WHO clinical stage II at HIV diagnosis (adjusted OR = 1.56;  = .033), and suppressed viral load (<1000 copies/mL), which was paradoxically associated with a higher risk of hypertension (adjusted OR = 0.42 for unsuppressed viral load;  = .041). No significant association was found with ART regimen lines.ConclusionHypertension affects more than one-third of PLWHIV in this urban HIV referral center, yet important gaps persist in treatment initiation, retention, and control. These findings highlight the urgent need for integrated hypertension screening and management strategies within HIV care services in Cameroon to reduce long-term cardiovascular risks.

People with HIV (PWH) experience high levels of mental health or substance use disorders (MSDs) which may compromise HIV treatment outcomes. Differences in the relationship between MSDs and HIV treatment outcomes by gender remain understudied. We conducted interviews with 426 PWH aged ≥ 21 years initiating HIV care in Cameroon between June 2019 and March 2020. Clinic data and laboratory results were used to ascertain loss to clinic and viral non-suppression six months after HIV care initiation. We used log binomial regression models to assess the relationship between symptoms of depression (PHQ-9 scores > 9), anxiety (GAD-7 scores > 9), post-traumatic stress disorder (PTSD; PCL-5 scores > 30), and harmful alcohol use (AUDIT scores > 15) at HIV care initiation and 6-month loss to clinic and viral non-suppression in the study population overall, and among men and women, separately. Nearly 25% of individuals (N = 100) were lost to clinic at 6 months. Among the 326 individuals retained in care at their original clinic at 6 months, 234 had a measured viral load, of whom 28% were virally non-suppressed (N = 65). Among men, the risk of disengagement was greater among those who reported PTSD symptoms at care initiation compared to those who did not. Viral non-suppression was significantly higher among those reporting symptoms of anxiety at care initiation in the population retained overall and among men. Men initiating HIV care with poor mental health may be particularly vulnerable to unstable care engagement and viral non-suppression. Interventions are needed for men specifically to foster improved mental health.

Eligibility for antiretroviral therapy is no longer based on immune criteria. In a global cohort of 97,453 children, between 2005 and 2021, we observed large declines in CD4 measurement, from 51% to 12% among <5 seconds, and from 74% to 20% among those 5-14 years of age. Lack of CD4 testing may negatively affect clinical care and surveillance of severe immune suppression.

As hypertension and diabetes emerge as co-morbidities among people living with HIV/AIDS (PLWH), the need for robust epidemiological research to inform policy and action is imperative. Proper reporting and handling of missing data are crucial in such studies to avoid loss of statistical power and precision and generate unbiased results. We aimed to assess the reporting and handling of missing data in published studies of co-morbid hypertension and diabetes among PLWH. We searched in PubMed for cross-sectional studies of co-morbid hypertension and diabetes among PLWH published worldwide between January 1990 and June 2023. We extracted data on reporting of missing data (quantity, type, where it occurred, and any bias assessment) and how it was handled. Of 2179 records identified, 154 studies were included among which 53 (34.4%) reported missing data, primarily within exposure variables such as CD4 count and viral load. Only 19 of these studies (37.7%) cited reasons for missingness, predominantly attributed to lack of documentation and non-response. Out of the 24 (45.5%) studies that detailed how they handled missing data, the majority (16 studies; 30.2%) used complete case analysis. Only 5/53 studies (9.43%) adopted multiple imputation methods. The potential biases introduced by missing data were acknowledged in only 12/53 (22.6%) studies. The reporting and handling of missing data in hypertension and diabetes studies among PLWH are currently suboptimal. Enhanced understanding of why data is missing and choosing appropriate methods to address it is paramount to reduce potential biases. Adopting and adhering to comprehensive guidelines for managing missing data is a pressing need and will ensure that more accurate results are better represented in PLWH population.

Addressing the mental health needs of people with HIV is critical to ending the HIV epidemic. Yet, empirical evidence on the downstream consequences of poor mental health at entry into HIV care is scant, limiting our ability to deploy appropriate interventions. Multistate methods can provide a nuanced picture of how longitudinal care engagement differs between those with and without mental ill-health. From June 2019 to March 2020, we enrolled people with HIV aged 21+ entering HIV care at three clinics in Cameroon. We conducted structured interviews to ascertain demographics and depression status (Patient Health Questionnaire-9 scores>9=heightened depressive symptoms) at enrolment and extracted participant clinical record data through 1 January 2022. We estimated the proportion of individuals and time spent in six mutually exclusive and exhaustive care states: linked to clinic; engaged at clinic, prescribed antiretroviral therapy; disengaged from clinic; re-engaged at clinic; known death and known transfer out across the first 18 months following entry. Further, we explored re-engagement patterns among those who disengaged. Estimates were compared for those with vs without heightened depressive symptoms. 420 people contributed 630.1 person-years of follow-up; 20% (n=84) had probable depression. A similar proportion of individuals with and without heightened depressive symptoms failed to return to the clinic after their first visit (~10%). However, those with heightened depressive symptoms were less likely to be continuously engaged in care at month 18 (prevalence difference=-14.3; 95% CI -27.0 to -2.3) and spent an average of ~40 fewer days (95% CI -78.4 to -1.2) engaged in care at their original clinic across follow-up compared with their counterparts. Of the 141 who disengaged from care, those with heightened depressive symptoms were less likely to be re-engaged 6 months later (prevalence difference=-10.2%; 95% CI -25.7 to 5.9). Routine depression screening and sustained support for people with HIV with heightened depressive symptoms are warranted to uphold these individuals' right to health and improve downstream outcomes.

Integrase mutations associated with dolutegravir resistance have been well characterized, but based on limited data from non-B subtypes. We aim to identify integrase mutations not currently classified as integrase strand transfer inhibitor (INSTI) resistance mutations (DRMs) in individuals with viremia on dolutegravir-based regimens. Mutations in integrase sequences in the DTG RESIST study from African countries were detected using Stanford HIVdb v9.8. We used a viral genome-wide association study (GWAS) approach to identify mutations not classified as major or accessory INSTI DRMs but associated with dolutegravir resistance. We performed the same GWAS on drug-naïve sequences from the Los Alamos HIV-1 database to identify mutations associated with viraemia under DTG exposure. Among 387 sequences, 107 (27.6%) showed at least intermediate dolutegravir resistance. Fourteen integrase mutations not classified as major or accessory DRMs (S39R, L45I, I72L, L74I, V79I, F100Y, I113V, S119R, V126A, K156N, Q177L, I208M, A265V, and R284G) were significantly associated with resistance. V79I (adjusted odds ratio [aOR] 169.2, 95% credible interval [CrI] 18.2-2871.4) and I72L (aOR 67.7, 95% CrI 7.1-1326.2) were strongly associated with resistance. S39R, L45I, I72L, L74I, V79I, F100Y, S119R, and K156N were linked to established INSTI resistance pathways, and I72L, L74I, V79I, V126A, and K156N were associated with viraemia under DTG exposure. We identified several integrase mutations outside established DRM categories that are strongly associated with dolutegravir resistance. Dolutegravir resistance evolution is complex; likely involves mutations not currently classified as DRMs.

Mental health disorders are common among people with HIV (PWH), and the overwhelming majority of PWH with mental health disorders do not receive evidence-based mental health care. One promising strategy to increase access to evidence-based mental health care for PWH is to integrate mental health screening and treatment for common mental disorders and unhealthy drinking into HIV care. However, little is known about how PWH view the role of HIV care providers in supporting their mental health or their experiences with mental health-related help-seeking. We conducted in-depth interviews with 30 PWH at three HIV treatment centers in Cameroon. Interviews were conducted in French or English. French transcripts were translated to English for analysis. Thematic analysis was used to identify key factors that influenced mental health-related help-seeking and respondents' preferred roles of HIV care providers. Overall, participants reported that they were less likely to seek support from medical providers for mental health compared to physical health needs. Previous positive contact with providers facilitated mental health help-seeking intentions among participants. Health facility characteristics, including limited provider availability, concerns about privacy and confidentiality, and high clinic volume were noted as barriers to mental health help-seeking at HIV facilities. Participants consistently reported that they desired positive, caring interactions with HIV care providers and clinic staff and noted that providers could play a critical role in helping PWH accept their HIV diagnosis and address HIV-related stigma and material needs. Overall, this sample of PWH in Cameroon reported that mental health-related help-seeking was limited in HIV care settings, but identified strategies that have the potential to enhance mental health related-help seeking in HIV care settings and may improve the mental health of PWH. The extent to which such strategies enhance mental health help-seeking and improve mental health should be evaluated.

While non-disclosure of HIV status may protect people living with HIV (PLWH) against stigma, discrimination, and violence, disclosure may facilitate access to social support and improve treatment adherence. This study examined factors associated with non-disclosure among recently-diagnosed PLWH at IeDEA study sites in Cameroon. We conducted a cross-sectional study of adults ≥ 19 years newly enrolling in HIV care at three Cameroon hospitals from January 2016 to June 2023 with recent (< 1 year) diagnoses and no evidence of prior HIV care. We used logistic regression to identify factors associated with non-disclosure of HIV status at the time of enrolment. Among 2880 participants, the overall prevalence of HIV status non-disclosure at enrolment was 34.4%, ranging from 48.0% among those enrolling on the day of diagnosis to 18.7% among those enrolling > 30 days after diagnosis. Men and single participants had higher odds of non-disclosure compared with women (aOR: 1.68; 95% CI 1.38, 2.04) and those who were married/living with a partner (aOR: 1.66; 95% CI 1.36, 2.02). Those with early-stage HIV disease (WHO Stage 1 or 2 or CD4 ≥ 200 cells/mm) also had higher odds of non-disclosure (aOR: 1.48; 95% CI 1.20, 1.83) compared with participants with advanced-stage disease. Among those diagnosed with HIV within 1 year prior to enrolment, men, single/unmarried people, and those with early-stage HIV disease were less likely to disclose their status. Further research on barriers to status disclosure among these groups is needed to guide disclosure support and counselling interventions.

Recent studies indicate that migraine affects 14-15% of the global population, tension-type headache (TTH) around 26%, and medication-overuse headache (MOH) 1-2%. While these estimates highlight the impact of these conditions on population health, their reliability is compromised by the variable quality of contributing studies. In response, the Global Campaign against Headache has supported epidemiological studies in all parts of the world, using standardized methods. We conducted a meta-analysis of individual participant data from these studies, accepting only population-representative data (17 countries from all world regions). All included studies were cross-sectional surveys of adults aged 18-65 years using the Headache-Attributed Restriction, Disability, Social Handicap and Impaired Participation (HARDSHIP) questionnaire. Algorithmic diagnosis applying modified International Classification of Headache Disorders (ICHD) criteria identified the headache disorders of public-health importance: migraine, TTH and probable MOH (pMOH: the association of headache on ≥ 15 days/month [H15+] and reported medication overuse). Two sets of estimates were made for migraine and TTH, one excluding those with H15+ (standard process), the other including these (extended process). We analysed associations with demographical variables, and, accordingly, adjusted prevalence estimates for age, gender and country income level. We included 41,614 individuals, with over-representations of females (22,278 [53.5%]) and of participants from lower-middle income countries (59.7%; global 37.8%). Age-distribution was similar to that of the world. Overall, 65.5% (95% CI: 65.0-66.0) reported headache during the previous year, females (72.1% [71.5-72.7]) more than males (57.9% [57.2-58.6]). Migraine was more common among females (standard process: 29.5% [28.9-30.1]; extended process: 33.1% [32.5-33.7]) than males (18.6% [18.1-19.2]; 20.1% [19.6-20.7]), as was pMOH (5.6% [5.3-5.9] vs. 2.3% [2.1-2.5]). TTH was similarly prevalent among males (33.4% [32.8-34.1]; 34.9% [34.2-35.5]) and females (31.2% [30.6-31.8]; 33.2% [32.6-33.8]). Headache was more prevalent in high/upper-middle income countries (71.4% [70.6-72.2]) than in low/lower-middle income (63.0% [62.5-63.6]). Prevalence estimates adjusted for age, gender and income level were 65.0% (64.6-65.5) for any headache, 23.5% (23.1-23.9; standard process) and 25.9% (25.4-26.3; extended process) for migraine, 33.2% (32.7-33.6) and 34.7% (34.3-35.2) for TTH, and 4.1% (3.9-4.3) for pMOH. About 65% of the world's population aged 18-65, likely to include most of the world's workforce, will have headache during the coming year, about 25% migraine and 4% pMOH. Both these estimates are higher than previous comparable estimates, and we believe them to be the best currently available for this population. Our estimate of TTH prevalence (about 33%) is probably substantially too low, since methodological constraints precluded identification of TTH in those with concomitant migraine.

Hospitalization for heart failure (HF) represents a pivotal event in the disease course, often signaling decompensation and an elevated risk of readmission, mortality, and functional decline. Despite advances in inpatient management, the transition from hospital to home remains a vulnerable period characterized by residual congestion, incomplete implementation of guideline-directed medical therapy (GDMT), unmanaged comorbidities, and fragmented care coordination. This expert consensus provides a comprehensive, evidence-based framework to optimize the pre-to-post discharge transition in patients hospitalized with HF. Key priorities include confirmation of decongestion using biomarkers, lung ultrasound, and validated risk scores; in-hospital initiation and up-titration of foundational GDMT; and identification of reversible etiologies such as ischemic heart disease. Early evaluation for device therapy, arrhythmia management, including anticoagulation and rhythm control in atrial fibrillation, and structured management of comorbidities such as chronic kidney disease, diabetes, COPD, iron deficiency, frailty, and depression are emphasized. Multidisciplinary collaboration across pharmacy, rehabilitation, mental health, and social services is essential to support safe discharge and continuity of care. Proactive strategies such as medication reconciliation, simplified dosing regimens, caregiver engagement, and attention to social determinants of health are critical to improving adherence and preventing avoidable readmissions. Early post-discharge follow-up (ideally within 7 days), remote monitoring, and ongoing GDMT optimization are central to management during the high-risk vulnerable phase. Cardiac rehabilitation, timely evaluation for advanced therapies, and integration of palliative care complete the continuum of care. This consensus proposes a structured, patient-centered approach that bridges inpatient stabilization with longitudinal outpatient management to reduce rehospitalizations, improve clinical outcomes, and enhance quality of life for patients living with HF.

The care of patients hospitalized for acute heart failure (AHF) has been largely unchanged from the early 1960s until a few years ago, consisting mainly of oxygen and diuretics supplemented sometimes by other vasoactive drugs. These treatments, although effective in the short term in controlling congestion, do not prevent early readmissions and death, occurring in over 30% of patients in the 6 months after an AHF hospitalization. In the last years, studies showed that AHF diagnosis can be improved, early diuretic care can be optimized, and early intensive therapy with combined drug regimens can reduce the rate of adverse outcomes. However, unlike acute coronary syndromes, where guidelines have existed since 1996, there are no separate detailed guidelines for AHF. In a series of four papers (International Expert Opinion Series on AHF Management) an international expert group highlights important aspects of AHF care where the evidence base to inform clinical practice is lacking. These papers focus on (1) diagnosis and treatment during prehospital and in the emergency department, (2) management during the first days of admission, (3) care before and after AHF discharge, and (4) hospitalized AHF management in patients presenting with cardiogenic shock, significant valvular disease, or end-stage renal disease. These papers are not intended to serve as guidelines, but rather to suggest a framework for future recommendations for the diagnosis and treatment of AHF. In the current summary paper, we highlight the main considerations and key recommendations in each of the parts of AHF care.

Acute heart failure (AHF) is diagnosed in about 0.5% of all patients seen by emergency medical systems (EMS) and represents about 1% of emergency department (ED) visits. Leg swelling and shortness of breath are the most frequent patient complaints. Despite significant advancements in patient care pathways, the proper diagnosis, treatment and disposition of AHF may be further improved in emergency settings. The present document is an expert consensus document outlining key points in diagnosis, treatment and decision-making of patients being diagnosed with AHF by EMS and in the ED. Pillars of correct diagnosis include detailed clinical assessment and accurate interpretation of natriuretic peptides, while chest X-ray is still the most frequent image test used in ED, that could be substituted by ultrasonography exploration in appropriate patients. Quick identification of the most severe cases needing intensive care is mandatory, most of them characterized by hemodynamic instability, ventilatory failure or acute coronary syndrome needing intervention. Treatment could be started in prehospital settings by EMS, and loop diuretics are still the cornerstone of decongestive therapy. Measurement of diuresis and natriuresis shortly after provision of the first diuretic bolus is recommended, as it can help in detecting patients with poor diuretic response for dose augmentation or drug escalation with the addition of acetazolamide or thiazides. For selected patients, vasodilators (especially for acute cardiogenic pulmonary edema phenotype) or inotropes/vasopressors (for those with cardiogenic shock) can be needed. Oxygen therapy should be provided to patients with air-room SpO 2 below 95%, and noninvasive ventilation is an option for patients with respiratory distress. After provision of ED care, a correct decision of patient discharge or hospitalization is paramount, and risk stratification can help in this regard. Other key points of AHF management in the ED include adequate diagnosis and management of triggers of the AHF episode; to take aspects of patient frailty into account; to avoid lines, catheters, and patient overstay in the ED where possible; and to ensure a proper follow-up plan after discharge from the hospital.

Mental health-related stigma is a prominent barrier to improved mental health outcomes globally and may be particularly harmful to populations with other stigmatized identities. We aimed to understand intersectional depression- and HIV-related stigma among people with HIV (PWH) entering HIV care in Cameroon. Using baseline data from a cohort of PWH entering HIV care in Cameroon between 2019 and 2020, we characterized depression- and HIV-related stigma in the population overall and by sociodemographic sub-group. We also explored substantively meaningful variation in stigma endorsement by depressive symptom severity (Patient Health Questionnaire-9 [PHQ-9]) and causal attribution of depression. Among those with elevated depressive symptoms (PHQ-9 scores > 4), we estimated the association between stigma type and depressive symptom severity using binomial regression. Among 398 participants, 49% endorsed low HIV- and depression-related stigma (N = 195), 10% endorsed high HIV- and depression-related stigma (N = 38), 29% endorsed high depression-related stigma only (N = 116), and 12% endorsed high HIV-related stigma only (N = 49). Respondents with and without heightened depressive symptoms commonly believed depressive symptoms were caused by HIV (N = 140; 32.9%). Among those with elevated depressive symptoms, the prevalence of moderate to severe symptoms was higher among those endorsing high HIV-related stigma only (prevalence ratio 1.55; 95% confidence interval: 1.01, 2.37) compared to those reporting low HIV- and depression-related stigma. HIV- and depression-related stigma are both common among PWH entering HIV care in Cameroon. The consistent association between HIV-related stigma and poor psychosocial well-being among people with HIV necessitates the urgent scale-up of evidence-based HIV-related stigma interventions specifically.

Mental disorders are common among people with HIV (PWH) and are associated with poor HIV outcomes. Despite high unmet mental health needs among PWH, use of evidence-based mental health screening and treatment protocols remains limited at HIV treatment facilities across low-resource settings. Integrating mental health services into HIV care can reduce this gap. This study's objective was to explore factors that influence integration of mental health screening and treatment into HIV clinics in Cameroon. We analyzed 14 in-depth interviews with clinic staff supporting PWH at three urban HIV treatment clinics in Cameroon. Interviews focused on current processes, barriers and facilitators, and types of support needed to integrate mental health care into HIV care. Interviews were recorded and transcribed. French transcripts were translated into English. We used thematic analysis to identify factors that influence integration of mental health screening and treatment into HIV care in these settings. Ethical review boards in the United States and Cameroon approved this study. Respondents discussed a lack of standardized mental health screening processes in HIV treatment facilities and generally felt ill-equipped to conduct mental health screening. Low community awareness about mental disorders, mental health-related stigma, limited physical space, and high clinic volume affected providers' ability to screen clients for mental disorders. Providers indicated that better coordination and communication were needed to support client referral to mental health care. Despite these barriers, providers were motivated to screen clients for mental disorders and believed that mental health service provision could improve quality of HIV care and treatment outcomes. All providers interviewed said they would feel more confident screening for mental disorders with additional training and resources. Providers recommended community sensitization, training or hiring additional staff, improved coordination to manage referrals, and leadership buy-in at multiple levels of the health system to support sustainable integration of mental health screening and treatment into HIV clinics in Cameroon. Providers reported enthusiasm to integrate mental health services into HIV care but need more support and training to do so in an effective and sustainable manner.

Knowledge of headache prevalence, and the burdens attributable to headache disorders, remains incomplete in sub-Saharan Africa (SSA): reliable studies have been conducted only in Zambia (southern SSA) and Ethiopia (eastern SSA). As part of the Global Campaign against Headache, we investigated the prevalence of headache in Cameroon, in Central SSA. We used the same methodology as the studies in Zambia and Ethiopia, employing cluster-randomized sampling in four regions of Cameroon, selected to reflect the country's geographic, ethnic and cultural diversities. We visited, unannounced, randomly selected households in each region, and randomly selected one adult member (aged 18-65 years) of each. Trained interviewers administered the Headache-Attributed Restriction, Disability and Impaired Participation (HARDSHIP) structured questionnaire, developed by an international expert consensus group and translated into Central African French. Demographic enquiry was followed by diagnostic questions based on ICHD-3 criteria. Headache was a near-universal experience in Cameroon (lifetime prevalence: 94.8%). Observed 1-year prevalence of headache was 77.1%. Age- and gender-adjusted estimates were 76.4% (95% confidence interval: 74.9-77.9) for any headache, 17.9% (16.6-19.3) for migraine (definite + probable), 44.4% (42.6-46.2) for tension-type headache (TTH; also definite + probable), 6.5% (5.7-7.4) for probable medication-overuse headache (pMOH) and 6.6% (5.8-7.6) for other headache on ≥ 15 days/month (H15 +). One-day prevalence ("headache yesterday") was 15.3%. Gender differentials were as expected (more migraine and pMOH among females, and rather more TTH among males). pMOH increased in prevalence until age 55 years, then declined somewhat. Migraine and TTH were both associated with urban dwelling, pMOH, in contrast, with rural dwelling. Headache disorders are prevalent in Cameroon. As in Zambia and Ethiopia, estimates for both migraine and TTH exceed global mean estimates. Attributable burden is yet to be reported, but these findings must lead to further research, and measures to develop and implement headache services in Cameroon, with appropriate management and preventative strategies.

Hospital readmission after discharge for stroke is associated with high morbidity and mortality. There is a paucity of data on the burden of stroke readmission in most sub-Saharan African countries. We aimed to determine the rate, reasons and predictors of hospital readmission and the mortality rate within 12 months of discharge among stroke survivors in Cameroon. This prospective cohort included patients who survived hospitalization for an acute stroke and who were discharged from two referral hospitals in the capital city of Cameroon between January 2013 and December 2013.We performed logistic regression analysis to identify demographic and clinical factors associated with readmission within 1 year of discharge and causes of readmission. Of the 254 consecutive patients admitted for acute stroke, 198 were discharged alive. There were 107 (54%) males, and their mean age (SD) was 61.7 (13.9) years (range: 10 to 95 years). A total of 30 (15.2%) patients were readmitted following discharge from the index admission over a mean follow-up time of 286.9 (127.6) days. Of these, 14 (46.7%) were discharged and 16 (53.3%) died after readmission. Thirty percent (30%) of readmissions occurred within the first month. The most frequent causes of readmissions were infections (30%) and recurrent stroke (26.7%). Factors associated with readmission in bivariate analysis were initial admission temperature > 37.5°C (risk ratio [RR]: 1.3, p = 0.021) and initial admission Glasgow Coma Score < 14 (RR: p = 1.23, p = 0.019). After stratified adjustment for age and sex, temperature > 37.5°C (adjusted RR: 1.3, 95% CI: 1-1.7, p = 0.036) and GCS <14 (adjusted RR: 1.23, 95% CI: 1-1.6, p = 0.041) were associated with readmission. Readmission after discharge for stroke was common with nearly one third occurring within the first month and more than half dying following readmission. The most common causes of readmission were infections and recurrent stroke.

Kenya has adopted the WHO target of halting the rise of overweight, including obesity, by 2025. This paper assesses the potential impact of achieving the set target on health, healthcare cost and productivity. We used a proportional multistate life table model () to simulate the 2019 population of Kenya over their lifetime. We compared a scenario in which body mass index (BMI) distributions stabilise in 2025 against one whose BMI distributions stabilise in 2044, and quantified changes in disease-specific health outcomes, healthcare costs and productivity. We searched the literature to identify the best estimates of the total and disease-specific healthcare costs in Kenya. We used the Human Capital Approach to estimate productivity gains. If BMI distributions stabilised in 2025, an estimated 6.8 million health-adjusted life years (HALYs) (95% uncertainty interval (UI) 5.8-7.9 million) would be saved over the lifetime of the 2019 Kenyan population (135 HALYs per 1000 persons). A total of US$755 million in body mass-related healthcare costs could be saved by 2044 (US$15 per capita). For context, this equates to 16% of Kenya's annual healthcare expenditure. Over the lifetime, ~US$3 billion healthcare costs could be saved (US$62 per capita). By 2044, the total productivity gain resulting from a reduction in high BMI-related mortality and morbidity (combined) was ~US$5.8 billion (~US$237 per capita). Achieving Kenya's overweight and obesity reduction target could improve health outcomes and also yield substantial healthcare cost savings and productivity gains.

Chronic venous disease is a global public health problem, with high morbidity and economic distress. There is scarcity of data on this disease in sub-Saharan Africa. We conducted the first population-based study over a period of 20 months from 1st February 2020 to 30th September 2021 in the 10 regions of Cameroon. A stratify sampling method was chose to select study site. Socio-demographic data, personal and family history, anthropometric parameters, clinical signs, illustrative images, CEAP (Clinical-Etiological-Anatomical-Pathophysiological) classification revised in 2004, VCSS (venous Clinical Severity Score) and risk factor assessment score were used to construct the survey form. Chi-squared test and Fischer exact test were used to compare the prevalence of chronic venous disease across different potential risk factors (sex, age category, previous history of deep vein thrombosis, hypertension, diabetes, smoking status, obesity). Simple and multiple logistic regression models were used to obtain crude and adjusted odds ratio for risk factors associated with chronic venous insufficiency. Statistical analyses were done with R version 4.2 for Linux and the threshold for statistical significance was 0.05. A total of 6578 participants were included in the study, with a mean age of 41.09 ± 16.02 years with female predominance (54.3%). The prevalence of chronic venous disease was 21.8% (95% CI: 20.8-22.9) and the prevalence of chronic venous insufficiency (C3-C6) was 7.02% ( = 462). Night cramps (43.2%), oedema (21.7%), lower limbs pain (20.4%) mostly worsens by walking and heavy legs (16.2%) were more common symptoms. The mean total venous clinical severity score was 0.69 ± 1.76 and this score had a significant positive correlation with C classification ( < .001). In the multivariate analysis, the following factors were independently associated with CVD: Male gender (aOR: 1.27; 95%CI: 1.04-1.56; = .021), retired people (aOR: 46.9; 95% CI: 12.6-174.5; < .001), hypertension (aOR: 289.5; 95%CI: 169.69-493.1; < .001), diabetes (aOR: 2.19; 95% CI: 1.21-3.96; = .009), obesity (aOR: 10.22; 95%CI: 7.67-13.62; < .001). Smoking appears as a protective factor (aOR: 0.18; 95%CI: 0.10-0.30; < .001). Chronic venous disease is frequent in Cameroon and main traditional cardiovascular risk factors are associated to this condition. Systematic screening of the CVD in these specific groups could reduce the burden of the disease and its economic impact.

We studied the transition to dolutegravir-containing antiretroviral therapy (ART) at HIV treatment clinics within the International epidemiology Databases to Evaluate AIDS (IeDEA). Site-level survey conducted in 2020-2021 among HIV clinics in low- and middle-income countries (LMICs). We assessed the status of dolutegravir rollout and viral load and drug resistance testing practices for persons on ART switching to dolutegravir-based regimens. We used generalized estimating equations to assess associations between clinic rollout of both first- and second-line dolutegravir-based ART regimens (dual rollout) and site-level factors. Of 179 surveyed clinics, 175 (98%) participated; 137 (78%) from Africa, 30 (17%) from the Asia-Pacific, and 8 (5%) from Latin America. Most clinics (80%) were in low- or lower-middle-income countries, and there were a mix of primary-, secondary- and tertiary-level clinics. Ninety percent reported rollout of first-line dolutegravir, 59% of second-line, 94% of first- or second-line and 55% of dual rollout. The adjusted odds of dual rollout were higher among tertiary-level [adjusted odds ratio (aOR) 4.00; 95% confidence interval (CI) 1.39-11.47] and secondary-level clinics (aOR 3.66; 95% CI 2.19-6.11) than in primary-level clinics. Over half (59%) of clinics that introduced first- or second-line dolutegravir-based ART required recent viral load testing before switching to dolutegravir, and 15% performed genotypic resistance testing at switch. Dolutegravir-based ART was rolled out at nearly all IeDEA clinics in LMICs, yet many switched persons to dolutegravir without recent viral load testing and drug resistance testing was rarely performed. Without such testing, drug resistance among persons switching to dolutegravir may go undetected.

We have previously shown headache to be highly prevalent in Cameroon. Here we present the attributed burden. We also perform a headache-care needs assessment. This was a cross-sectional survey among adults (18-65 years) in the general population. Multistage cluster-sampling in four regions (Centre, Littoral, West and Adamawa), home to almost half the country's population, generated a representative sample. We used the standardised methodology of the Global Campaign against Headache, including the HARDSHIP questionnaire, with diagnostic questions based on ICHD-3 and enquiries into symptom burden, impaired participation (lost productivity and disengagement from social activity), quality of life (QoL) using WHOQoL-8, and willingness to pay (WTP) for effective care. We defined headache care "need" in terms of likelihood of benefit, counting all those with probable medication-overuse headache (pMOH) or other headache on ≥ 15 days/month (H15 +), with migraine on ≥ 3 days/month, or with migraine or tension-type headache (TTH) and meeting either of two criteria: a) proportion of time in ictal state (pTIS) > 3.3% and intensity ≥ 2 (moderate-to-severe); or b) ≥ 3 lost days from paid and/or household work in the preceding 3 months. Among 3,100 participants, mean frequency of any headache was 6.7 days/month, mean duration 13.0 h and mean intensity 2.3 (moderate). Mean pTIS was 9.8%, which (with prevalence factored in) diluted to 6.1-7.4% of all time in the population. Most time was spent with H15 + (5.3% of all time), followed by TTH (1.0%) and migraine (0.8%). For all headache, mean lost days/3 months were 3.4 from paid work, 3.0 from household work and 0.6 from social/leisure activities, diluting to 2.5, 2.2 and 0.6 days/3 months in the population. QoL (no headache: 27.9/40) was adversely impacted by pMOH (25.0) and other H15 + (26.0) but not by migraine (28.0) or TTH (28.0). WTP (maximally XAF 4,462.40 [USD 7.65] per month) was not significantly different between headache types. An estimated 37.0% of adult Cameroonians need headache care. Headache disorders in Cameroon are not only prevalent but also associated with high attributed burden, with heavily impaired participation. Headache-care needs are very high, but so are the economic costs of not providing care.

Measures ascertaining exposure to potentially traumatic events (PTEs) frequently ask respondents about experienced physical and sexual violence. However, little is known about the performance of physical and sexual violence questions on PTE assessments and its effect on PTE classification overall. We estimated underreporting of physical and sexual violence on a PTE assessment among individuals entering HIV care in Cameroon. We compared reports of physical and sexual violence captured via a behaviorally specific measure of intimate partner violence (IPV; Demographic and Health Survey [DHS] domestic violence module = referent) to those captured via two single-item questions that assessed exposure to physical and sexual PTEs during one's adult life to determine the degree of underreporting on the single-item PTE assessment questions. We explored correlates of underreporting on the PTE assessment using Pearson's chi-squared tests. Overall, 99 (23%) and 113 (27%) of 426 total participants reported instances of sexual and physical violence in their most recent partnership on the behaviorally specific DHS IPV module, respectively. Of those reporting sexual and physical IPV on the DHS module, just 6% ( = 6) and 52% ( = 59) reported sexual and physical violence as an adult on the single-item PTE assessment questions, respectively. Underreporting of physical violence on the PTE assessment was associated with lower educational attainment ( < .05) and reporting being punched ( < .01) or having one's hair pulled or arm twisted ( < .05) by one's most recent partner. PTE assessment tools should assess exposure to behaviorally specific acts of violence to ensure appropriate referral to services among survivors of IPV.

The association between HIV infection and increased cardiometabolic risk, attributed to chronic inflammation in people living with HIV (PLWH) and/or antiretroviral therapy (ART) effects, has been inconsistent. In this study, we aimed to assess the associations of HIV-related factors with hypertension (HTN) and type-2 diabetes mellitus (T2DM), and the potential mediation effects of body mass index (BMI) in the associations between ART use and HTN or T2DM in PLWH in Cameroon. A cross-sectional study was conducted with 14,119 adult PLWH from Cameroon enrolled in the International epidemiology Databases to Evaluate AIDS (IeDEA) between 2016 and 2021. HTN was defined as systolic/diastolic blood pressure ≥ 140/90 mmHg and/or current use of antihypertensive medication, while T2DM was defined as fasting blood sugar ≥ 126 mg/dL and/or use of antidiabetic medications. Univariable and multivariable multinomial logistic regression analyses examined the associations of factors with HTN alone, T2DM alone, and both (HTN + T2DM). Mediation analyses were conducted to assess the potential mediation roles of BMI, while controlling for age, sex, and smoking. Of the 14,119 participants, 9177 (65%) were women, with a median age of 42 (25-75th percentiles: 35-51) years. Age > 50 years was associated with HTN alone, T2DM alone, and HTN + T2DM compared to the age group 19-29 years. Men had higher odds of having HTN + T2DM. Overweight and obesity were predictors of HTN alone compared to being underweight. WHO stages II and III HIV disease were inversely associated with HTN alone compared to stage I. The odds of diabetes alone were lower with ART use. BMI partially mediated the association between ART use and hypertension, with a proportion of mediation effect of 49.6% (all p < 0.02). However, BMI did not mediate the relationship between ART use and diabetes. Traditional cardiovascular risk factors were strongly associated with hypertension among PLWH, while HIV-related exposures had smaller associations. BMI partially mediated the association between ART use and hypertension. This study emphasizes the importance of screening, monitoring, and managing HTN and T2DM in older, male, and overweight/obese PLWH. Further research on the associations of HIV disease stage and ART use with HTN and T2DM is warranted.

To inform public health policymakers that the generation of local evidence-based knowledge is key. Research capacity in low- and middle-income countries (LMIC) to generate medical knowledge is often weak and insufficiently resourced and efforts to tackle these challenges are not standardized. Continuous research training can equip researchers with the required knowledge and research skills, but its effectiveness largely depends on the quality and pertinence of the training methods used. We aim to assess the effectiveness of the Cameroon HIV/AIDS Research Forum (CAM-HERO) 2022 Research Methodology and Bioethics Training with the objective to describe the knowledge gained and the self-efficacy of health professionals and clinical scientists. A survey was conducted during the one-day training among health professionals and clinical scientists. Participants took an online self-administered questionnaire before and after the training related to the topics taught. The questionnaire consisted of two parts: 1) 18 Multiple Choice Questions (MCQs) to assess knowledge and 2) Nine items to evaluate self-efficacy using a five-point Likert scale. Mean scores were calculated, analysed, and compared using paired t-test for the pre- and post-test results. A total of 30 participants (57% women) completed the socio-demographic form. The median age (IQR) of participants was 33.5 (13.3) years. We registered 38 respondents for the pre-test and 33 respondents for the post-test. There was a rise in knowledge mean score from 13.0 to 14.8 (p=0.001) and an improvement in the perception of self-efficacy with a mean score increase from 2.9 to 3.7 (p < 0.001). Knowledge and perception of self-efficacy on research methodology improved among participants after the training. These results suggest that the CAM-HERO 2022 training had an immediate positive impact on skills and self-efficacy. Hence, we recommend the implementation of this training on a larger scale, periodically, and with long-term follow-up to evaluate its impact.

Intimate partner violence (IPV) has been associated with poor mental health among people with HIV (PWH) globally. Social support may be a strategy to foster mental health among PWH. Little is known about whether the relationship between IPV and mental health differs by IPV type or level of social support. Interviews were conducted with 426 PWH initiating HIV care in Cameroon. Log binomial regression analyses were used to estimate the association between four types of IPV (controlling behavior and emotional, physical, and sexual IPV) and symptoms of depression or hazardous alcohol use, separately by IPV type and level of social support. Over half (54.8%) of respondents experienced moderate/high levels of controlling behavior, 42.0% experienced emotional IPV, 28.2% experienced physical IPV and 23.7% experienced sexual IPV. Controlling behavior was associated with greater prevalence of depressive symptoms. This relationship did not vary meaningfully by level of social support (low: aPR 2.4 [95% CI 1.2, 4.9]; high: 1.7 [95% CI 1.0, 2.7]). Emotional and physical IPV were associated with greater prevalence of depressive symptoms among those with low social support (emotional IPV: aPR 1.9 [95% CI 1.0, 3.4]; physical IPV: aPR 1.8 [95% CI 1.2, 2.8]), but not among those with high social support (emotional IPV: aPR 1.0 [95% CI 0.7, 1.6]; physical IPV: aPR 1.0 [95% CI 0.6, 1.6]). Controlling behavior, emotional IPV, and physical IPV were associated with a greater prevalence of hazardous alcohol use, with moderately larger effect estimates among those with high compared to low social support. Sexual IPV was not associated with depressive symptoms or hazardous alcohol use. Services to screen and care for people experiencing IPV are urgently needed among PWH in Cameroon. Future research to identify barriers, feasibility, acceptability, and organizational readiness to integrate IPV and mental health services into HIV care settings is needed.

Hypertension is the leading cause of morbidity and mortality in sub-Saharan Africa (SSA). Current guidelines recommend using two or more antihypertensive agents in single pill combinations (SPCs) to treat hypertension, but data from African patients that support these recommendations are lacking. We assessed the effectiveness and tolerance of three SPCs in lowering blood pressure (BP) amongst hypertensive patients in Douala. All patients included in the hypertension registry of the Douala General Hospital and the Douala Cardiovascular Center between January 2010 and May 2020, and receiving a two-drug SPCs (renin-angiotensin system inhibitors (RAASi) + diuretics (DIU), calcium channel blockers (CCB) + RAASi, or DIU + CCB) were tracked from baseline through 16 weeks. Our primary outcome was a decrease in systolic BP (SBP) from baseline up to 16 weeks after initiation of treatment. A mixed linear repeated model was used to evaluate the change of SBP from baseline to week 16, while controlling for age, gender, and baseline SBP. Statistical significance was set at p < 0.05. Of 377 participants on two-drug SPCs, 123 were on CCB + DIU, 96 on RAASi + CCB, and 158 on RAASi + DIU. The mean age was 54.6 (± 11.2) years. At baseline, participants on RAASi + CCB presented with slightly higher SBP compared to the other two groups. Overall, the SBP decreased by 34.3 (± 14.2) mmHg from baseline values and this was comparable across the three groups of SPCs (p = 0.118). The control rate after 16 weeks of follow-up was 62.3% with no significant difference between groups. The occurrence of adverse events was 3.4% and was comparable among the three groups. The three two-drug SPCs were highly effective in reducing and controlling BP with low and similar rates of adverse effects. Long-term data documenting safety and whether these agents exert a differential cardiovascular effect in addition to and independent of their BP-lowering effect are needed for SSA populations.

This study explored the relationship between specific types of potentially traumatic events (PTEs) and symptoms of mental health disorders among people with HIV (PWH) in Cameroon. We conducted a cross-sectional study with 426 PWH in Cameroon between 2019-2020. Multivariable log binominal regression was used to estimate the association between exposure (yes/no) to six distinct types of PTE and symptoms of depression (Patient Health Questionnaire-9 score > 9), PTSD (PTSD Checklist for DSM-5 score > 30), anxiety (Generalized Anxiety Disorder-7 scale score > 9), and hazardous alcohol use (Alcohol Use Disorders Identification Test score > 7 for men; > 6 for women). A majority of study participants (96%) reported exposure to at least one PTE, with a median of 4 PTEs (interquartile range: 2-5). The most commonly reported PTEs were seeing someone seriously injured or killed (45%), family members hitting or harming one another as a child (43%), physical assault or abuse from an intimate partner (42%) and witnessing physical assault or abuse (41%). In multivariable analyses, the prevalence of PTSD symptoms was significantly higher among those who reported experiencing PTEs during childhood, violent PTEs during adulthood, and the death of a child. The prevalence of anxiety symptoms was significantly higher among those who reported experiencing both PTEs during childhood and violent PTEs during adulthood. No significant positive associations were observed between specific PTEs explored and symptoms of depression or hazardous alcohol use after adjustment. PTEs were common among this sample of PWH in Cameroon and associated with PTSD and anxiety symptoms. Research is needed to foster primary prevention of PTEs and to address the mental health sequelae of PTEs among PWH.

Low-grade chronic inflammation may persist in spontaneous human immunodeficiency virus controllers (HICs), leading to non-AIDS-defining events (nADEs). Two hundred twenty-seven antiretroviral therapy (ART)-naive HICs (known human immunodeficiency virus type 1 [HIV-1] infection ≥5 years and at least 5 consecutive viral loads [VLs] <400 HIV RNA copies/mL) were compared with 328 patients who initiated ART ≤1 month after primary HIV infection diagnosis and had undetectable VL within 12 months following ART initiation for at least 5 years. Incidence rates of first nADEs were compared between HICs and ART-treated patients. Determinants of nADEs were assessed by using Cox regression models. All-cause nADEs incidence rates were 7.8 (95% confidence interval [CI], 5.9-9.6) and 5.2 (95% CI, 3.9-6.4) per 100 person-months among HICs and ART patients, respectively (incidence rate ratio [IRR], 1.5 [95% CI, 1.1-2.2]; adjusted IRR, 1.93 [95% CI, 1.16-3.20]). After adjustment for the cohort, demographic, and immunological characteristics, the only other factor associated with all-cause nADE occurrence was age ≥43 (vs <43) years at the beginning of viral control (IRR, 1.69 [95% CI, 1.11-2.56]). The most frequent events observed in the 2 cohorts were non-AIDS-related benign infections (54.6% and 32.9% of all nADEs, respectively, for HICs and ART patients). No differences in cardiovascular or psychiatric events were observed. HICs experienced 2 times more nADEs than virologically suppressed patients on ART, mainly non-AIDS-related benign infections. Older age was associated with nADE occurrence, independent of immune or virologic parameters. These results do not argue in favor of expanding the ART indication for HICs but rather a case-by-case approach considering clinical outcomes such as nADEs besides immune activation.

HIV-related stigma has been associated with poor mental health among people with HIV (PWH). Social support is a potentially modifiable factor that may buffer negative mental health sequelae of HIV-related stigma. Little is known about the extent to which the modifying effect of social support differs across mental health disorders. Interviews were conducted with 426 PWH in Cameroon. Log binomial regression analyses were used to estimate the association between high anticipated HIV-related stigma and low social support from family or friends and symptoms of depression, anxiety, post-traumatic stress disorder (PTSD), and harmful alcohol use, separately. Anticipated HIV-related stigma was commonly endorsed with ∼80% endorsing at least 1 of 12 stigma-related concerns. In multivariable analyses, high anticipated HIV-related stigma was associated with greater prevalence of symptoms of depression {adjusted prevalence ratio (aPR) 1.6 [95% confidence interval (CI) 1.1-2.2]} and anxiety [aPR 2.0 (95% CI 1.4-2.9)]. Low social support was associated with greater prevalence of symptoms of depression [aPR 1.5 (95% CI 1.1-2.2)], anxiety [aPR 1.7 (95% CI 1.2-2.5)], and PTSD [aPR 1.6 (95% CI 1.0-2.4)]. However, social support did not meaningfully modify the relationship between HIV-related stigma and symptoms of any mental health disorders explored. Anticipated HIV-related stigma was commonly reported among this group of PWH initiating HIV care in Cameroon. Social concerns related to gossip or losing friends were of the greatest concern. Interventions focused on reducing stigma and strengthening support systems may be particularly beneficial and have the potential to improve the mental health of PWH in Cameroon.

Politically motivated violence and insecurity continue to be a major threat to progress in HIV epidemic control and a significant contributor to health inequality. Despite a decreasing HIV/AIDS disease burden, the Republic of Cameroon in West Africa is experiencing ongoing political instability in her North and South West Regions. Our study used qualitative methods to better understand key frontline health care providers' (fHCP) perceptions of the effects of political instability on HIV/AIDS response gains in Cameroon since 2018, as well as lessons learned for overcoming them. Between July and August 2022, semi-structured, in-depth key informant interviews involving 10 purposively selected participants were conducted in the two regions. Interviews were recorded and transcribed verbatim, coded thematically, and analyzed manually. Six overarching themes emerged from the transcribed key informant interviews. They were as follows: Challenge with access to and availability of health care services (HIV care, commodity supply chain) in the smaller communities; Impact on continuity of treatment; Increased risk of new HIV infections; The socioeconomic impact of the crisis on the quality of life; The impact of the crisis on fHCPs' physical and mental health and the health system'; and Coping mechanisms. Frontline healthcare workers have acknowledged the significant impact the current political instability has had in hindering the development and advancement of a successful local response to HIV/AIDS in the two impacted regions of Cameroon. Coordinated efforts must be made to strengthen the health sector in areas such as HIV healthcare decentralization, supply chain, and protecting frontline healthcare workers from political quagmires in order to lessen the impact of the nation's socio-political crisis on the HIV/AIDS response and, more generally, on the entire health sector.

Little is known about the coping strategies used among people with HIV (PWH), especially in sub-Saharan Africa, and the extent to which adaptive or maladaptive coping strategies are associated with symptoms of mental health disorders. We interviewed 426 PWH initiating HIV care in Cameroon and reported the prevalence of adaptive and maladaptive coping strategies, overall and by presence of symptoms of depression, anxiety, and PTSD. Log binominal regression was used to estimate the association between each type of coping strategy (adaptive or maladaptive) and symptoms of each mental health disorder, separately. Adaptive and maladaptive coping strategies were commonly reported among PWH enrolling in HIV care in Cameroon. Across all mental health disorders assessed, greater maladaptive coping was associated with higher prevalence of depression, anxiety, and PTSD. Adaptive coping was not associated with symptoms of any of the mental health disorders assessed in bivariate or multivariable models. Our study found that PWH endorsed a range of concurrent adaptive and maladaptive coping strategies. Future efforts should explore the extent to which coping strategies change throughout the HIV care continuum. Interventions to reduce maladaptive coping have the potential to improve the mental health of PWH in Cameroon.

Metabolic syndrome (MetS) is a core driver of cardiovascular diseases (CVD); however, to date, gender differences in MetS prevalence and its components have not been assessed in the Algerian adult general population. This study aimed to determine the gender differences in MetS prevalence and its components, in the general population of Algeria. Secondary analysis was performed on data from the Algerian 2016-2017 non-communicable disease risk factor survey. MetS was determined according to the harmonized Joint Interim Statement criteria. A Poisson regression model based on Generalised Estimating Equations was used to estimate the adjusted prevalence ratios (aPR) for the sex-specific factors associated with MetS. Overall, the prevalence of MetS was 34.0% (95% CI 32.4-35.6). MetS prevalence in women and men was 39.1% (95% CI 37.0-41.3) and 29.1% (95% CI 27.2-31.2), respectively. The most frequent triad was the clustering of abdominal obesity with low HDL-cholesterol and high blood pressure among women (8.9%; 95% CI [8.0-10.0]) and low HDL-cholesterol with high blood pressure and hyperglycaemia among men (5.2%; 95% CI [4.3-6.3]). Increasing age (aPR 3.21 [2.35-4.39] in men and aPR 3.47 [2.86-4.22] in women), cohabitation (aPR 1.14 [1.05-1.24]), women residing in urban areas (aPR 1.13 [1.01-1.26]), men with higher educational levels (aPR 1.39 [1.14-1.70]), and men with insufficient physical activity (aPR 1.16 [1.05-1.30]) were associated with higher risk of MetS. In this population-based study, one in three Algerian adults had MetS, and key components including abdominal obesity, low HDL-cholesterol, and high blood pressure, are very common, especially in women. Reinforcing interventions for weight management targeting married women living in urban areas and improving sufficient physical activity in men with higher socioeconomic status could provide maximal health gains and stem the CVD epidemic in Algeria.

The global increase in mean body mass index has resulted in a substantial increase of non-communicable diseases (NCDs), including in many low- and middle-income countries such as Kenya. This paper assesses four interventions for the prevention and control of overweight and obesity in Kenya to determine their potential health and economic impact and cost effectiveness. We reviewed the literature to identify evidence of effect, determine the intervention costs, disease costs and total healthcare costs. We used a proportional multistate life table model to quantify the potential impacts on health conditions and healthcare costs, modelling the 2019 Kenya population over their remaining lifetime. Considering a health system perspective, two interventions were assessed for cost-effectiveness. In addition, we used the Human Capital Approach to estimate productivity gains. Over the lifetime of the 2019 population, impacts were estimated at 203,266 health-adjusted life years (HALYs) (95% uncertainty interval [UI] 163,752 - 249,621) for a 20% tax on sugar-sweetened beverages, 151,718 HALYs (95% UI 55,257 - 250,412) for mandatory kilojoule menu labelling, 3.7 million HALYs (95% UI 2,661,365-4,789,915) for a change in consumption levels related to supermarket food purchase patterns and 13.1 million HALYs (95% UI 11,404,317 - 15,152,341) for a change in national consumption back to the 1975 average levels of energy intake. This translates to 4, 3, 73 and 261 HALYs per 1,000 persons. Lifetime healthcare cost savings were approximately United States Dollar (USD) 0.14 billion (USD 3 per capita), USD 0.08 billion (USD 2 per capita), USD 1.9 billion (USD 38 per capita) and USD 6.2 billion (USD 124 per capita), respectively. Lifetime productivity gains were approximately USD 1.8 billion, USD 1.2 billion, USD 28 billion and USD 92 billion. Both the 20% tax on sugar sweetened beverages and the mandatory kilojoule menu labelling were assessed for cost effectiveness and found dominant (health promoting and cost-saving). All interventions evaluated yielded substantive health gains and economic benefits and should be considered for implementation in Kenya.

Atrial fibrillation is associated with increased risk of morbidity and mortality. There's limited data on the outcomes of atrial fibrillation patients in Africa. We aimed at evaluating the clinical outcomes and their associated factors in patients with atrial fibrillation on antithrombotic therapy in Douala. The Douala atrial fibrillation registry is a prospective, observational cohort study of patients with atrial fibrillation followed by cardiovascular specialists in 3 specialized care centres. From January to April 2018, all patients with electrocardiographic diagnosis of atrial fibrillation, aged 21 years or older, were included in the registry provided their consent. The composite endpoint of heart failure, stroke, major bleeding, hospitalisation and mortality as well as their individual occurrence were assessed at 12 months. Of 113 participants that were included, 6(5.3%) were lost to follow-up. The mean age was 70 ± 12 years, with a female predominance (68%). After a mean follow-up time of 12.2 ± 0.7 months, 51 patients (47.7%) had at least one outcome. Hospitalisation, all-cause mortality, heart failure, stroke and major bleeding rates were 33.3%, 16.8%, 15.2%, 4.8% and 2.9% respectively. There was no significant difference in the composite outcome and mortality according to the antithrombotic treatment. Previous heart failure [aHR = 3.07, 95% CI (1.48-6.36) p = 0.003], new onset atrial fibrillation [aHR= 4.00, 95% CI (0.96-8.19) p < 0.001] and paroxystic atrial fibrillation [aHR= 3.74, 95% CI (1.33-10.53) p = 0.013] were significant predictors of outcome. Half of patients with atrial fibrillation in this registry developed an outcome after one year of follow-up, with heart failure, new onset and paroxystic atrial fibrillation being the main predicting factors. Diagnosing and managing atrial fibrillation in patients with heart disease should therefore be considered as a key priority.

Comorbid depression and heavy episodic drinking (HED) may threaten the success of "treat all" policies in sub-Saharan Africa as the population of people with HIV (PWH) ages. We investigated associations between depressive symptoms and heavy episodic drinking (HED) and the extent the relationship differed across ages among PWH receiving HIV care in Cameroon. We conducted a retrospective analysis of 18-60-year-old PWH on antiretroviral therapy in Cameroon from January 2016 to March 2020. Age-varying effect modelling was conducted to assess associations between depressive symptoms and HED across ages and by gender. Prevalence of depression and HED was highest at ages 20 and 25, respectively. After age 25, the magnitude of the association between depressive symptoms and HED was significant and increased until age 30 (aOR: 1.88, 95% CI: 1.48, 2.39), with associations remaining significant until age 55 (aOR: 1.64, 95% CI: 1.17, 2.29). Women had more variability and higher magnitudes of associations between depressive symptoms and HED than men. The interrelationship between depressive symptoms and HED was significant throughout most of adulthood for PWH receiving HIV care in Cameroon. Understanding age and gender trends in these associations can guide integration efforts in HIV care settings.

People living with HIV/AIDS (PLHIV) are at increased risk of cardiometabolic diseases attributable to the effects of the virus, antiretroviral therapy (ART) and traditional risk factors. Most studies have focused on assessing the effect of ART on cardiometabolic diseases in PLHIV with fewer studies assessing the cardiometabolic risk profile prior to exposure to ART. Therefore, this protocol is for a systematic review and meta-analysis to estimate the global prevalence of selected cardiometabolic risk factors in ART-naïve PLHIV and their association with HIV specific factors. We shall conduct a systematic search of observational studies on the prevalence of obesity, hypertension, diabetes, and dyslipidaemia in ART-naïve PLHIV and their association with HIV specific characteristics. We will search PubMed-MEDLINE, CINAHL, SCOPUS, Academic Search Premier, Africa-Wide Information and Africa Journals Online databases to identify relevant studies published before June 2022. Two authors will independently screen, select studies, extract data, and conduct risk of bias assessments. Disagreements between the two authors will be resolved by consensus or consulting a third reviewer. Data consistently reported across studies will be pooled using random-effects meta-analysis. Heterogeneity will be evaluated using Cochrane's Q statistic and quantified using I2 statistics. The Preferred Reporting Items for Systematic reviews and Meta-Analysis protocols (PRISMA-P) 2015 guidelines are used for the reporting of this protocol. This review will help determine the burden of selected cardiometabolic diseases in ART-naïve HIV-infected populations and the contribution of HIV infection, independent of ART, to cardiometabolic diseases in PLHIV. It will provide new information that can help orientate future research and potentially guide healthcare policy making. This is part of a thesis that will be submitted to the Faculty of Health Sciences, University of Cape Town, for the award of a PhD in Medicine with protocol ethical clearance number (UCT HREC 350/2021).

Home blood pressure management, including self-monitoring and medication self-titration, is an efficient and cost-effective tool. Although its use is increasing globally, little is known about the feasibility of such interventions in low and middle-income countries. Further, the perspectives and experiences of healthcare providers who play a big role in ensuring the success of home blood pressure management interventions have not been documented. This qualitative study was conducted with a total of 35 healthcare providers (60% female, mean [SD] age = 37.3 [6.9 years] years), through 4 in-depth interviews from Peru, and 8 in-depth interviews and 4 focus groups from Cameroon. Study participants (healthcare providers) include physicians (primary care physicians), specialists (cardiologists and geriatricians), and nurses that were purposively recruited from two hospitals in two of the largest cities in both countries. Results were thematically analyzed by two researchers. Themes derived were related to feasibility and acceptability, and largely reflected providers in both countries endorsing home blood pressure management. Providers' concerns were in three main areas; 1) safety of patients when they self-titrate medications, 2) resources such as healthcare financing, local hospital policies that support communications with patients for home blood pressure management, and 3) sustainability through patient adherence, incorporating home blood pressure management within clinical guidelines and hospital policies, and complementing with continued health education and lifestyle modifications. According to providers, home blood pressure management may be feasible and acceptable if tailored multi-faceted protocols were introduced bearing in mind local contexts.

Heart failure (HF) is a growing public health concern with a high mortality rate in sub-Saharan Africa. However, few studies have reported the long-term predictors of mortality in this region. This study sought to determine the 3-year mortality rate and the predictors of mortality amongst HF patients in Douala, Cameroon. We conducted a prospective analysis on patients recruited in the Douala Heart Failure (Do-HF) registry, an ongoing prospective data collection on patients with HF at four cardiology units in Douala, Cameroon. Patients included were followed for 36 months from the index date of inclusion, with all-cause mortality as the primary outcome. Cox proportional hazard regression models were used to determine predictors of mortality. Out of the 347 participants included, 318 (91.6%) completed follow-up. The mean age was 64±14 years, 172 (49.6%) were men. Hypertensive cardiomyopathy and dilated cardiomyopathy were the most frequent causes of heart failure. The median follow-up was 33 months, and 150 (47.2%) patients died. Independent predictors of mortality included New York Heart Association functional class III & IV (aHR 2.23; 95% CI: 1.49-3.33; P<0.001), presence of pulmonary rales (aHR 1.87; 95% CI: 1.30-2.68; P=0.005), chronic kidney disease (aHR 2.92; 95% CI: 1.79-4.78; P<0.001), enrolment as inpatient (aHR1.96; 95% CI: 1.17-2.54; P=0.005), no formal education (aHR 2.06; 95% CI: 1.28-3.33; P=0.003), and a monthly income of at most three minimum wage (aHR 2.06; 95% CI: 1.28-3.33; P=0.003). This study shows that almost half of HF patients die after 36 months of follow-up. Also, late presentation and poverty-related conditions were associated with poor outcomes. These findings suggest prioritizing preventive strategies that target early diagnosis and socioeconomic status to improve the prognosis of HF.

post-partum depression is one of the many challenges associated with childbirth. In Cameroon, the focus is more on post-partum obstetric complications resulting in underdiagnosis and misdiagnosis of this condition. The current socio-political crisis plaguing the English-speaking part of Cameroon has increased the stressors that may inherently increase the prevalence. There is no published data describing post-partum depression in a rural setting in Cameroon. We seek to determine the prevalence and factors associated with PPD in women attending the Tubah District hospital, North West Region, Cameroon. we conducted a cross-sectional hospital-based study at the Tubah District Hospital. A consecutive convenience sampling technique was used to recruit participants. Our main outcome was post-partum depression which was assessed using the Edinburgh Post-partum Depression Scale. a total of 207 post-partum women took part in this study with a mean age of 27.54 ± 5.78 years. The prevalence of depression was 31.8%. Gender-based violence (OR: 4.67, P = 0.013), financial stress (OR: 3.57, P = 0.002) and male baby (OR: 2.83, P < 0.001) were independent psychosocial factors associated with PPD. Independent psycho-clinical factors of post-partum depression include family history of mental health illness (OR: 4.34, P = 0.04) and previous history of depression (OR: 4.17, P = 0.02). the prevalence of post-partum depression in women attending the Tubah District Hospital, Northwest Region, Cameroon is high. The factors associated with PPD are many. Identification of risk factors, early diagnosis and proper management can prevent PPD, disabling morbidity, and suicide in mothers.

Depression is associated with suboptimal HIV care outcomes. Little is known about the extent to which the prevalence of depressive symptoms varies across the HIV care continuum. Also, the relationship among gender, HIV disclosure, HIV care stage, and depressive symptoms in PLWH remains poorly understood. We analyzed cross-sectional data from 12,507 PLWH at enrollment in International epidemiology Databases to Evaluate AIDS (IeDEA) Cameroon between 2016 and 2020. Recent depressive symptoms were assessed using the Patient Health Questionnaire-2 (PHQ-2). A score of three or greater on the PHQ-2 was considered indicative of likely major depressive disorder. We estimated the prevalence of depressive symptoms across three stages of HIV care: those not yet on antiretroviral therapy (ART), recent ART initiators (ART initiation ≤ 30 days prior), and ART users (ART initiation > 30 days prior). Adjusted prevalence differences (aPD) of depressive symptoms were estimated comparing recent ART initiators and ART users. Disclosure and gender were examined as effect measure modifiers of the relationship between HIV care stage and depressive symptoms. The prevalence of depressive symptoms was 11.9%, 22.0%, and 8.7% among PLWH not yet on ART, recent ART initiators, and ART users, respectively. ART users had significantly lower prevalence of depressive symptoms compared to recent ART initiators (aPD - 0.09 [95% CI - 0.11, - 0.08]). Neither gender nor HIV disclosure modified the effect measure of the relationship between HIV care stage and depressive symptoms. Depressive symptoms were commonly reported among this group of PLWH and were associated with recent ART initiation. Integration of screening and treatment of depression into HIV care should be prioritized and may be particularly relevant for PLWH initiating ART.

Dolutegravir is being scaled up globally as part of antiretroviral therapy (ART), but for people with HIV and tuberculosis co-infection, its use is complicated by a drug-drug interaction with rifampicin requiring an additional daily dose of dolutegravir. This represents a disadvantage over efavirenz, which does not have a major drug-drug interaction with rifampicin. We sought to describe HIV clinic practices for prescribing concomitant dolutegravir and rifampicin, and characterize virologic outcomes among patients with tuberculosis co-infection receiving dolutegravir or efavirenz. Within the four sub-Saharan Africa regions of the International epidemiology Databases to Evaluate AIDS consortium, we conducted a site survey (2021) and a cohort study (2015-2021). The cohort study used routine clinical data and included patients newly initiating or already receiving dolutegravir or efavirenz at the time of tuberculosis diagnosis. Patients were followed from tuberculosis diagnosis until viral suppression (<1000 copies/ml), a competing event (switching ART regimen; loss to program/death) or administrative censoring at 12 months. In the survey, 86 of 90 (96%) HIV clinics in 18 countries reported prescribing dolutegravir to patients who were receiving rifampicin as part of tuberculosis treatment, with 77 (90%) reporting that they use twice-daily dosing of dolutegravir, of which 74 (96%) reported having 50 mg tablets available to accommodate twice-daily dosing. The cohort study included 3563 patients in 11 countries, with 67% newly or recently initiating ART. Among patients receiving dolutegravir (n = 465), the cumulative incidence of viral suppression was 58.9% (95% confidence interval [CI]: 54.3-63.3%), switching ART regimen was 4.1% (95% CI: 2.6-6.2%) and loss to program/death was 23.4% (95% CI: 19.7-27.4%). Patients receiving dolutegravir had improved viral suppression compared with patients receiving efavirenz who had a tuberculosis diagnosis before site dolutegravir availability (adjusted subdistribution hazard ratio [aSHR]: 1.47, 95% CI: 1.28-1.68) and after site dolutegravir availability (aSHR 1.28, 95% CI: 1.08-1.51). At a programmatic level, dolutegravir was being widely prescribed in sub-Saharan Africa for people with HIV and tuberculosis co-infection with a dose adjustment for the drug-drug interaction with rifampicin. Despite this more complex regimen, our cohort study revealed that dolutegravir did not negatively impact viral suppression.

Psychiatric comorbidity, the presence of two or more mental health disorders, has been associated with suboptimal HIV treatment outcomes. Little is known about the prevalence of psychiatric comorbidity among people with HIV (PWH) in sub-Saharan Africa. We conducted interviews with PWH initiating HIV care in Cameroon between June 2019 and March 2020. Depression, anxiety, post-traumatic stress disorder (PTSD), and harmful drinking were dichotomized to represent those with and without symptoms of each. Psychiatric comorbidity was defined as having symptoms of two or more disorders assessed. Moderate or severe household hunger, high anticipatory HIV-related stigma, low social support, and high number of potentially traumatic events were hypothesized as correlates of psychiatric comorbidity. Bivariable log binomial regression models were used to estimate unadjusted associations between psychosocial stressors and psychiatric comorbidity. Among 424 participants interviewed, the prevalence of psychiatric comorbidity was 16%. Among those with symptoms of at least one mental health or substance use disorder (n = 161), the prevalence of psychiatric comorbidity was 42%. The prevalence of psychiatric comorbidity was 33%, 67%, 76%, and 81% among those with symptoms of harmful drinking, depression, anxiety, and PTSD, respectively. Among individuals with symptoms of a mental health or substance use disorder, a high number of potentially traumatic events (prevalence ratio (PR) 1.71 [95% CI 1.21, 2.42]) and high anticipatory HIV-related stigma (PR 1.45 [95% CI 1.01, 2.09]) were associated with greater prevalence of psychiatric comorbidity. Psychiatric comorbidity was common among this group of PWH in Cameroon. The effectiveness and implementation of transdiagnostic or multi-focus mental health treatment approaches in HIV care settings should be examined.

about 257 million people are infected with hepatitis B virus (HBV) worldwide and the infection is endemic in Africa. The general population HBV seroprevalence remains under-reported in Cameroon. this was a cross-sectional study including, 1208 consenting adults selected through consecutive sampling, from April 2015 to November 2018, in the Bamenda Health District. Participants´ demographic data were collected and their blood samples were drawn and tested for hepatitis B Surface Antigen (HBsAg). Data were analysed using SPSS version 24 and Chi-squared and Fisher´s exact tests were used to assess bivariate associations. the participants´ mean age (years) was 35.9±11.8, and the majority were females 720 (59.6%). The seroprevalence of HBV infection was 5.8% (95% CI: 4.5-7.3), and was significantly higher in males 8.4% (95% CI: 6.2-11.1), p=0.001, age group 30-39 years 8.4% (95% CI: 5.8-11.6), p=0.007 and the Mankon health area (12.7%; 95% CI: 9.1-17.1), p=0.026. the results suggest that HBV infection could be intermediately endemic in Bamenda, with a higher burden in males, people in their third decade and those from the Mankon health area. This study further underscores a need for extensive screening and vaccination campaigns in Cameroon.

Exposure to stressors increases the risk of mental health disorders. People living with HIV (PLWH) are particularly affected by poor mental health which can contribute to adverse HIV treatment outcomes. We estimated the prevalence of recent stressful life events (modified Life Events Survey) among a cohort of PLWH entering HIV care at three public health care facilities in Cameroon and quantified the association of seven types of stressful life events with symptoms of depression (Patient Health Questionnaire-9 scores>9), anxiety (General Anxiety Disorder-7 scores>9), and PTSD (PTSD Checklist for DSM-5 scores>30) using separate log-binomial regression models. Of 426 PLWH enrolling in care, a majority were women (59%), in relationships (58%), and aged 21 to 39 years (58%). Recent death of a family member (39%) and severe illness of a family member (34%) were the most commonly reported stressful life events. In multivariable analyses, more stressful life event types, a negative relationship change, death or illness of a friend/family member, experience of violence, work-related difficulties, and feeling unsafe in one's neighborhood were independently associated with at least one of the mental health outcomes assessed. The greatest magnitude of association was observed between work-related difficulties and PTSD (adjusted prevalence ratio: 3.1; 95% confidence interval: 2.0-4.8). Given the design of our study, findings are subject to recall and social desirability bias. Stressful life events were common among this population of PLWH entering care in Cameroon. Evidence-based interventions that improve coping, stress management, and mental health are needed.

Ideal Cardiovascular Health (CVH) is a concept defined by the American Heart Association (AHA) as part of its 2020 Impact Goals. Until now, changes in ideal CVH have been poorly evaluated in Sub-Saharan African populations. We aimed to investigate changes in the prevalence of ideal CVH and its components in a population of Malawian adults. Secondary analysis was done on cross-sectional data from 2009 to 2017, obtained from the Malawi STEPS surveys which included 5730 participants aged 25-64 years. CVH metrics categorized into "ideal (6-7 ideal metrics)", "intermediate (3-5 ideal metrics)" and "poor (0-2 ideal metrics)" were computed using blood pressure, body mass index (BMI), fasting glycaemia, fruit and vegetable intake, physical activity, smoking, and total cholesterol. Sampling weights were used to account for the sampling design, and all estimates were standardised by age and sex using the direct method. The mean participant age across both periods was 40.1 ± 12.4 years. The prevalence of meeting ≥ 6 ideal CVH metrics increased substantially from 9.4% in 2009 to 33.3% in 2017, whereas having ≤ 2 ideal CVH metrics decreased from 7.6% to 0.5% over this time. For the individual metrics, desirable levels of smoking, fruit and vegetable intake, physical activity, blood pressure (BP), total cholesterol and fasting glucose all increased during the study period whilst achievable levels of BMI (< 25 kg/m) declined. From 2009 to 2017, the mean number of ideal CVH metrics was higher in women compared to men (from 2.1% to 5.1% vs 2.0% to 5.0%). However, poor levels of smoking and fruit and vegetable intake were higher in men compared to women (from 27.9% to 23.6% vs. 7.4%% to 1.9% , and from 33.7% to 42.9% vs 30.8% to 34.6%, respectively). Also, whilst achievable levels of BMI rose in men (from 84.4% to 86.2%) the proportion reduced in women (from 72.1% to 67.5% ). Overall, CVH improved in Malawian adults from 2009 to 2017 and was highest in women. However, the prevalence of poor fruit and vegetable intake, and poor smoking remained high in men whilst optimal levels of BMI was declined in women. To improve this situation, individual and population-based strategies that address body mass, smoking and fruit and vegetable intake are warranted for maximal health gains in stemming the development of cardiovascular events.

Kidney dysfunction is common in patients with heart failure (HF) and has been associated with poor outcomes. This study aimed to determine the prevalence, correlates, and prognosis of kidney dysfunction in patients with HF in Cameroon, an understudied population. We conducted a cross-sectional study in consecutive patients hospitalized with HF between June 2016 and November 2017 in the Buea Regional Hospital, Cameroon. Kidney dysfunction was defined as an estimated glomerular filtration rate < 60 ml/min/1.73m. Prognostic outcomes included death and prolonged hospital stay (> 7 days). We also performed a sensitivity analysis excluding racial considerations. Seventy four patients (86.1% of those eligible) were included. Their median age was 60 (interquartile range: 44-72) years and 46.0% (n = 34) were males. Half of patients (n = 37) had kidney dysfunction. Correlates of kidney dysfunction included previous diagnosis of HF (adjusted odds ratio [aOR]4.3, 95% CI: 1.1-17.5) and left ventricular hypertrophy (aOR3.4, 95% CI: 1.1-9.9). Thirty-six (48.9%) had prolonged hospital stay, and seven (9.5%) patients died in hospital. Kidney dysfunction was not associated with in-hospital death (aOR 0.4, 95% CI: 0.1-2) nor prolonged hospital stay (aOR 2.04, 0.8-5.3). In sensitivity analysis (excluding racial consideration), factors associated with Kidney dysfunction in HF were; anemia (aOR: 3.0, 95% CI: 1.1-8.5), chronic heart failure (aOR: 4.7, 95% CI: 0.9-24.6), heart rate on admission < 90 bpm (aOR: 3.4, 95% CI: 1.1-9.1), left atrial dilation (aOR: 3.2, 95% CI: 1.04-10), and hypertensive heart disease (aOR: 3.1, 95% CI: 1.2-8.4). Kidney dysfunction in HF was associated with hospital stay > 7 days (OR: 2.6, 95% CI: 1-6.8). Moderate-to-severe kidney dysfunction was seen in half of the patients hospitalized with HF in our setting, and this was associated with a previous diagnosis of HF and left ventricular hypertrophy. Kidney dysfunction might not be the main driver of poor HF outcomes in this population. In sensitivity analysis, this was associated with anemia, chronic heart failure, heart rate on admission less than 90 bpm, left atrial dilatation, and hypertensive heart disease. Kidney dysfunction was associated with hospital stay > 7 days.

Interruptions in treatment pose risks for people with HIV (PWH) and threaten progress in ending the HIV epidemic; however, the COVID-19 pandemic's impact on HIV service delivery across diverse settings is not broadly documented. From September 2020 to March 2021, the International epidemiology Databases to Evaluate AIDS (IeDEA) research consortium surveyed 238 HIV care sites across seven geographic regions to document constraints in HIV service delivery during the first year of the pandemic and strategies for ensuring care continuity for PWH. Descriptive statistics were stratified by national HIV prevalence (<1%, 1-4.9% and ≥5%) and country income levels. Questions about pandemic-related consequences for HIV care were completed by 225 (95%) sites in 42 countries with low (n = 82), medium (n = 86) and high (n = 57) HIV prevalence, including low- (n = 57), lower-middle (n = 79), upper-middle (n = 39) and high- (n = 50) income countries. Most sites reported being subject to pandemic-related restrictions on travel, service provision or other operations (75%), and experiencing negative impacts (76%) on clinic operations, including decreased hours/days, reduced provider availability, clinic reconfiguration for COVID-19 services, record-keeping interruptions and suspension of partner support. Almost all sites in low-prevalence and high-income countries reported increased use of telemedicine (85% and 100%, respectively), compared with less than half of sites in high-prevalence and lower-income settings. Few sites in high-prevalence settings (2%) reported suspending antiretroviral therapy (ART) clinic services, and many reported adopting mitigation strategies to support adherence, including multi-month dispensing of ART (95%) and designating community ART pick-up points (44%). While few sites (5%) reported stockouts of first-line ART regimens, 10-11% reported stockouts of second- and third-line regimens, respectively, primarily in high-prevalence and lower-income settings. Interruptions in HIV viral load (VL) testing included suspension of testing (22%), longer turnaround times (41%) and supply/reagent stockouts (22%), but did not differ across settings. While many sites in high HIV prevalence settings and lower-income countries reported introducing or expanding measures to support treatment adherence and continuity of care, the COVID-19 pandemic resulted in disruptions to VL testing and ART supply chains that may negatively affect the quality of HIV care in these settings.

The COVID-19 pandemic has impacted population health around the globe, directly and indirectly. The objective of this study was to document changes in HIV care associated with the COVID-19 pandemic at selected clinics in Central Africa, along with clinic-level strategies for minimizing disruptions in HIV care and treatment for people with HIV (PWH). A 51-item questionnaire on COVID-19 pandemic-associated changes in HIV service delivery was completed by clinicians involved in HIV care at 21 clinics in five countries participating in Central Africa International epidemiology Databases to Evaluate AIDS (CA-IeDEA). The survey was completed at two timepoints: June-July 2020 and October 2020 to February 2021. Descriptive statistics were used to characterize changes in HIV care and related services. While 81% of sites reported at least one negative consequence of COVID-19 for clinic operations during the first survey, none reported suspending antiretroviral therapy (ART) initiation services for new patients, and 24% reported adopting telemedicine. In the follow-up survey, fewer sites (48%) reported at least one disruption to clinic operations, and more sites reported mitigation strategies, including expanding rapid ART initiation services and providing extra supplies of ART medications to reduce visit frequency. In the follow-up survey, more sites, especially in Rwanda, reported stockouts of commodities, including HIV and viral load testing and HIV pre-exposure prophylaxis. More than one-fifth of sites reported stockouts of second- or third-line ART at each survey timepoint. While the initial wave of the COVID-19 pandemic resulted in concerning disruptions to HIV service delivery at CA-IeDEA sites, most of these disruptions attenuated over time, and many sites introduced measures to help PWH avoid frequent visits to the clinic for care and medications. The impact of HIV commodity stockouts and clinic mitigation strategies on treatment outcomes needs to be assessed.

In 2020, the world was confronted with COVID-19, which caused a socio-economic panic in several sectors. The use of hospitals has been affected, with an impact on their financial performance. The objective of this study was to assess the effect of the pandemic on the financial performance of a hospital with a care center. This was a cross-sectional study targeting the Yaoundé Central Hospital over two periods : before the pandemic (March to August 2019) and during the pandemic (March to August 2020). Based on the administrative accounts, revenues from the main sources of financial inflows were recorded and compared before and during the pandemic. From March to August 2019, overall revenue was 1,131,525,099 FCFA and from March to August 2020, it was 762,770,714 FCFA, representing a drop of 32.6%. Medical imaging showed a drop of 14% corresponding to a loss of 96,500,052 FCFA. The laboratory showed a 21% decrease corresponding to a loss of 80,691,347 FCFA. Hospital admissions fell by 21%, corresponding to a loss of 62,124,675 FCFA. Consultations fell by 10%, corresponding to a loss of 49,265,835 FCFA. The COVID-19 pandemic had a negative effect on the financial revenues of the Yaoundé Central Hospital.

Armed conflicts are a major contributor to global disease burden owing to their deleterious effects on health and healthcare delivery. The Anglophone crisis in Cameroon is one of the ongoing conflicts in Sub-Saharan Africa and has led to massive displacement of healthcare workers (HCWs). However, some HCWs have stayed back and continued working. An understanding of their experiences, perspectives and professional perseverance is lacking. We designed a phenomenological study using Focused Group Discussions (FGDs) and in-depth interviews to: understand the experiences of 12 HCWs in a remote hospital in the North West region of Cameroon with armed groups; evaluate how it affects healthcare delivery from HCWs perspective and examine HCWs coping mechanisms during the conflict with a view of informing HCW protection policies in conflict zones. Results revealed that HCWs go through all forms of violence including threats, assaults and murders. Overall insecurity and shortage of health personnel were major barriers to healthcare delivery which contributed to underutilization of healthcare services. Participants observed an increase in complications due to malaria, malnutrition and a rise in maternal and infant mortality. The hospital management and Non-Governmental Organizations (NGOs) played an essential role in HCWs adaptation to the crisis. Nevertheless they unanimously advocated for a cease fire to end the conflict. In the meantime, passion for their job was the main motivating factor to stay at work.

Heavy alcohol use is common among people with HIV (PWH), leading to sub-optimal HIV care outcomes. Yet, heavy episodic drinking (HED) is not routinely addressed within most HIV clinics in sub-Saharan Africa. HIV disclosure may provide social support, potentially reducing HED to cope with HIV. We examined the prevalence of HED and HIV disclosure by antiretroviral treatment (ART) status among PWH receiving HIV care in Cameroon. We analyzed routine HIV clinical data augmented with systematic alcohol use data among adult PWH receiving HIV care in three regional hospitals from January 2016 to March 2020. Recent HED prevalence was examined across PWH by ART status: those not on ART, recent ART initiators (ART initiation ≤30 days prior), and ART users (ART initiation >30 days prior); and by gender. We used log-binomial regression to estimate prevalence differences (PD) between HIV disclosure and recent HED by ART status. Among 12,517 PWH in care, 16.4% (95%CI: 15.7, 17.0) reported recent HED. HED was reported among 21.2% (95%CI: 16.0, 26.3) of those not on ART, 24.5% (95%CI: 23.1, 26.0) of recent ART initiators, and 12.9% (95%CI: 12.2, 13.6) of ART users. Regardless of ART status, men were more likely than women to report HED. Those who disclosed HIV status had a lower HED prevalence than those who had not disclosed (aPD: -0.07; 95%CI: -0.10, -0.05) and not modified by gender. The prevalence of recent HED was high among PWH in care. HED prevalence was highest among men and recent ART initiators. Longitudinal analyses should explore how HIV disclosure may support PWH in reducing or abstaining from HED through social support. Systematic HED screening and referral to care should be included in routine HIV clinical care, particularly for men, to improve engagement in the HIV care continuum in Cameroon.

Since the first reported case of the coronavirus disease 2019 (COVID-19) in Wuhan China, the virus has spread to every continent, including sub-Saharan Africa. There exist no cure or vaccine for COVID-19. Classic public health approaches such as hygiene and sanitation, and social distancing are the recommended measures to contain the spread of the causative virus. While it is possible to combine strict lockdown measures in some western countries, this is not practical in almost every country in sub-Saharan Africa. In Cameroon, those without symptoms are encouraged to respect measures of hygiene and sanitation, physical distancing, and to wear a mask in public places. Those who develop symptoms are isolated in accredited COVID-19 management centres until they recover. However, the latter strategy is ineffective in containing the local spread of the virus because testing is not robust. Intuitively, the control of the virus in Cameroon depends largely on how engaged the public is in fighting against the virus. Social media can complement the use of community health workers for community or public engagement. In this viewpoint, we discuss how to optimize public engagement, to combat misinformation and to develop a culture for preparedness amidst the COVID-19 pandemic when time and resources are of the essence.

There is evidence that cardiac pacemakers improve symptoms and quality of life in patients with severe bradycardia. Globally, the number of pacemaker implantations is on the rise. However, the associated high-cost limits pacemaker's accessibility in low resource settings. This study aimed to investigate access to pacemakers and the long-term outcome of patients requiring a pacemaker. We conducted a cohort study in 03 health care structures in Cameroon. Participants aged at least 18 years with indication for a permanent pacemaker between January 2010 and May 2016 were included. Clinical profile, electrocardiography, pacemaker implantation parameters were recorded. Long-term survival was studied by event-free analysis using the Kaplan-Meier method. In total, 147 participants (mean age 67.7±13.7 years, female 58.5%) were included. Fatigue (78.7%), dyspnoea (77.2%), dizziness (47.1%) and palpitations (40.4%) were the main symptoms while syncope was present in 35.7% of patients. The main indication for cardiac pacemaker was atrioventricular block (85.3%). Forty (27.2%) could not be implanted with 34 (85%) of participants highlighting cost of intervention as main reason. VVIR was the main mode of stimulation (70.5%). Of 125 patients in which follow-up was ascertained, 17(13.5%) died after a median survival time of 2.8 years post diagnosis [IQR: 1.8-4.2]. The survival curve was better in participants with a pacemaker with a Hazard ratio of 2.7 [CI: 1.0-7.3, P=0.045]. Our patients with severe heart blocks presented late and more than a quarter did not have access to pacemaker but its implantation multiplied the survival rate by 2.7 times at approximately 3 years post diagnosis. Improving early detection of heart blocks and access to cardiac pacing to reduce mortality shall be a key future priority.

Delays in diagnosis and linkage to HIV care persist among people living with HIV (PLWH), even after expanded access to ART worldwide. Mental health may influence timely linkage to HIV care. Greater understanding of the relationship among gender, mental health, and delayed linkage to HIV care can inform strategies to improve the health of PLWH. We interviewed 426 PLWH initiating HIV care in Cameroon between June 2019 and March 2020 to estimate the prevalence of depression, anxiety, and post-traumatic stress disorder (PTSD) and the association between mental health and entry into care with advanced HIV. Separate multivariable log binomial regression models were used to estimate the association between mental health exposure and entry into HIV care with advanced HIV. Stratified analyses were used to assess effect modification by gender. Approximately 20, 15, and 12% of participants reported symptoms of depression, PTSD, and anxiety, respectively. The prevalence of mental health symptoms did not vary significantly by gender. Overall, 53% of participants enrolled in HIV care with advanced HIV: 51% of men and 54% of women. Screening positive for one of the mental health disorders assessed was associated with greater prevalence of enrollment with advanced HIV among men, but not among women. Future research should examine gender-specific pathways between mental health symptoms and entry into care with advanced HIV, particularly for men in Cameroon. The extent to which untreated mental health symptoms drive gender disparities throughout the HIV care continuum should be explored further.

Mental health and substance use disorders (MSDs) increase the risk of poor human immunodeficiency virus (HIV) care outcomes among people living with HIV (PLWH). Receipt of mental health care may improve these adverse outcomes. We aimed to identify correlates of prior mental health help-seeking among PLWH with symptoms of an MSD in Cameroon. We characterize prior mental health help-seeking from formal (mental health specialist/general medical provider) and informal (traditional healer/religious leader) sources among 161 people with symptoms of depression (Patient Health Questionnaire-9 scores> 9), anxiety (General Anxiety Disorder-7 scores> 9), probable post-traumatic stress disorder (PTSD Checklist for DSM-5 scores> 30), or possible alcohol use disorder (Alcohol Use Disorders Identification Test scores≥16) who were newly entering HIV care at three healthcare facilities in Cameroon between June 2019 and March 2020. Help-seeking was defined as ever speaking to a formal or informal source about emotional problems, sadness, or the way they were feeling or behaving. We estimated the association between sociodemographic and psychosocial measures and lifetime mental health help-seeking from each type of source using log-binomial regression. Overall, 55.3% of 161 PLWH with MSD symptoms reported prior mental health help-seeking, with 24.2% and 46.0% seeking help from formal and informal sources, respectively. Religious leaders were the most common source of help (40.4%), followed by general medical professionals (22.4%), traditional healers (16.8%), and mental health specialists (7.4%). Individuals with higher depressive, anxiety, and trauma symptom severity scores were more likely to have sought help than those with lower scores. Individuals with possible alcohol use disorder were the least likely to have sought help. Prior help-seeking was more common among those reporting a higher number of lifetime traumatic events (prevalence ratio [PR]: 1.06; 95% confidence interval [CI]: 1.01, 1.11) and those with a history of emotional intimate partner violence (PR: 1.34; 95% CI: 1.01, 1.80). Prior mental health help-seeking was associated with psychosocial stressors. Help-seeking from informal networks was more common than formal help-seeking. Training in the provision of evidence-based mental health support for informal networks could improve access to mental health care for PLWH with MSDs in Cameroon.

Several anthropometric measurements are variably recommended to assess adiposity in routine practice, with less agreement on their comparative performance. We assessed and compared the relationship of seven anthropometric measures of adiposity-waist circumference (WC), waist-to-height ratio (WHtR), Body Mass Index (BMI), Ponderal Index (PI), Conicity Index (C index), A Body Shape Index (ABSI), and Body Roundness Index (BRI)-with blood pressure (BP) levels and prevalent hypertension in adult Cameroonians. Data were collected as Cameroon's contribution to the global May Measurement Month 2017(MMM17) survey. Participants were nonpregnant adults, who had no BP measurement in the past year and with no prior hypertension diagnosis. Hypertension was defined as systolic BP ≥140 mm Hg and/or diastolic ≥90 mm Hg. Odds ratios (ORs) for the presence of hypertension per 1 SD increase in each adiposity metrics were estimated in separate logistic regression models. Assessment and comparison of discrimination used the area under the receiver operating characteristics curve (AUC) and nonparametric methods. We included 14 424 participants (8210 [58.25%] female; 39.84 ± 14.33 years). There was a graded association between measures of adiposity and prevalent screen-detected (newly diagnosed) hypertension, with effect sizes being mostly within the same range across measures of adiposity. AUC for hypertension prediction ranged from 0.709 with PI to 0.721 with BRI for single measures, and from 0.736 to 0.739 with combinations of measures of adiposity. WC, WHtR, and BRI were strongly associated with BP and better predicted prevalent hypertension, with effects enhanced with the inclusion of BMI.

Higher resting heart rate (HR) is associated with mortality amongst Caucasians with heart failure (HF), but its significance has yet to be established in sub-Saharan Africans in whom HF differs in terms of characteristics and etiologies. We assessed the association of HR with all-cause mortality in patients with HF in sub-Saharan Africa. The Douala HF registry (Do-HF) is an ongoing prospective data collection on patients with HF receiving care at four cardiac referral services in Douala, Cameroon. Patients included in this report were followed-up for 12 months from their index admission, for all-cause mortality. We used Cox-regression analysis to study the association of HR with all-cause mortality during follow-up. Of 347 patients included, 343 (98.8%) completed follow-up. The mean age was 64±14 years, 176 (50.7%) were female, and median admission HR was 85 bpm. During a median follow-up of 12 months, 78 (22.7%) patients died. Mortality increased steadily with HR increase and ranged from 12.2% in the lower quartile of HR (≤69 bpm) to 34.1% in the upper quartile of HR (>100 bpm). Hazard ratio of 12-month death per 10 bpm higher HR was 1.16 (1.04-1.29), with consistent effects across most subgroups, but a higher effect in participants with hypertension . those without (interaction P=0.044). HR was independently associated with increased risk of all-cause mortality in this study, particularly among participants with hypertension. The implication of this finding for risk prediction or reduction should be actively investigated.

retaining patients in antiretroviral treatment (ART) is essential for successful outcomes. Unfortunately, Cameroon continues to report suboptimal ART retention. This study focused on identifying determinants of ART retention in three HIV clinics in Cameroon within the HIV treat all context. a medical chart review of 423 subjects who initiated ART between July and September 2016 in the Limbe, Bamenda and Jamot Hospitals. Patients' sociodemographic and clinical characteristics and ART retention data were abstracted using structured paper forms. Chi square test was used to assess bivariate associations. Logistic regression was used to adjust for confounders. P-value was set at <0.05 at 95% confidence interval. the mean age was 40±11 years, and 65.1% were females. Antiretroviral treatment retention after 24 months was 309/392 (78.83%) and 30/423 (7.1%) were transferred-out, 11/423 (2.6%) reported dead and 73/423 (17.3%) lost to follow-up. HIV status disclosure (AOR 0.16 95% CI: 0.05-0.51, p<0.01) and age group 31-50 years (AOR 3.63, 95% CI: 1.04-12.59, P= 0.04) were associated with lower and higher ART retention respectively. about a quarter of the participants were not retained in ART after 24 months. Patient-level factors determined ART retention. These factors should be considered in designing strategies to improve ART retention. More research is needed to identify other determinants of ART retention under the HIV treat all strategy.

Overweight and obesity are major public health problems worldwide, with projections suggesting a proportional increase in the number of affected individuals in developing countries by the year 2030. Evidence-based preventive strategies are needed to reduce the burden of overweight and obesity in developing countries. We assessed the prevalence of, and factors associated with overweight and obesity in selected health areas in West Cameroon. Data were collected from a community-based cross-sectional study, involving the consecutive recruitment of participants aged 18 years or older. Overweight and obesity were defined according to the WHO classification. The statistical software R (version 3.5.1, The R Foundation for statistical computing, Vienna, Austria) was used for statistical analysis. Multivariable logistic regression analysis was used to assess independent factors associated with overweight and obesity, and obesity. Records of 485 participants were included for analysis. The age and sex-standardized prevalence of overweight, obesity, and overweight and obesity were 31.1% (95% CI, 27.0-35.2), 18.9% (95% CI, 14.9-22.9), and 50.1% (95% CI, 45.7-54.6), respectively. In multivariable analysis, being female (adjusted OR [aOR] = 2.79, 95% CI = 1.69-4.63), married (aOR = 3.90, 95% CI = 2.23-6.95), and having secondary or tertiary education (aOR = 3.27, 95% CI = 1.77-6.17) were associated with higher odds of overweight and obesity, while current smokers had lower odds of overweight and obesity (aOR = 0.37, 95% CI = 0.16-0.82) when compared to their respective counterpart. Compared to their respective reference categories, being female being (aOR = 3.74, 95% CI = 2.01-7.30), married (aOR = 2.58, 95% CI = 1.37-5.05) and having secondary or tertiary education (aOR = 2.03, 95% CI = 1.00-4.23) were associated with higher odds of obesity after adjustments for confounding. We observed a high prevalence of overweight and obesity in this study. The odds of overweight and obesity was higher in females, married participants, and those with higher levels of education. Community-based interventions to control overweight and obesity should consider targeting these groups.

Rapid antiretroviral treatment (ART) initiation reduces time from HIV infection to viral suppression, decreasing HIV transmission risk. Mental health symptoms may influence timing of ART initiation. This study estimated the prevalence of ART initiation at enrolment into HIV care and the relationship between mental health and ART initiation at enrolment into HIV care. We conducted interviews with 426 individuals initiating HIV care in Cameroon between June 2019 and March 2020 to estimate the association between mental health and timing of ART initiation. Depression (Patient Health Questionnaire-9; cut-point 10), anxiety (Generalized Anxiety Disorder-7; cut-point 10), post-traumatic stress disorder (PTSD) (PTSD Checklist for DSM-5; cut-point 31) and harmful alcohol use (Alcohol Use Disorders Identification Test; cut-point 16) were dichotomized to represent those with and without each exposure at first HIV care appointment. Date of ART initiation (date ART prescribed) was ascertained from medical records. Separate multivariable log-binomial regression models were used to estimate the association between mental health exposures and ART initiation at enrolment into care. Overall, 87% initiated ART at enrolment into HIV care. Approximately 20% reported depressive symptoms, 15% reported PTSD symptoms, 12% reported anxiety symptoms and 13% reported harmful alcohol use. In multivariable analyses, individuals with moderate to severe depressive symptoms had 1.7 (95% confidence interval [CI] 1.1, 2.7) times the prevalence of not initiating ART at enrolment into HIV care compared to those with no or mild depressive symptoms. Those with symptoms of PTSD, compared to those without, had 1.9 (95% CI 1.2, 2.9) times the prevalence of not initiating ART at enrolment into HIV care. Symptoms of anxiety or harmful drinking were not associated with ART initiation at enrolment into HIV care in multivariable models. Symptoms of depression and PTSD were associated with lower prevalence of ART initiation at enrolment into HIV care among this sample of individuals initiating HIV care in Cameroon under a "treat all" policy. Research should examine barriers to timely ART initiation, whether incorporating mental health services into HIV care improves timely ART initiation, and whether untreated symptoms of depression and PTSD drive suboptimal HIV care outcomes.

Cardiovascular disease (CVD) is the largest contributor to the non-communicable diseases (NCD) burden in Cameroon, but data on its economic burden is lacking. A prevalence-based cost-of-illness study was conducted from a healthcare provider perspective and enrolled patients with ischaemic heart disease (IHD), ischaemic stroke, haemorrhagic stroke and hypertensive heart disease (HHD) from two major hospitals between 2013 and 2017. Determinants of cost were explored using multivariate generalized linear models. Overall, data from 850 patients: IHD (n = 92, 10.8%), ischaemic stroke (n = 317, 37.3%), haemorrhagic stroke (n = 193, 22.7%) and HHD (n = 248, 29.2%) were analysed. The total cost for these CVDs was XAF 676,694,000 (~US$ 1,224,918). The average annual direct medical costs of care per patient were XAF 1,395,200 (US$ 2400) for IHD, XAF 932,700 (US$ 1600) for ischaemic stroke, XAF 815,400 (US$ 1400) for haemorrhagic stroke, and XAF 384,300 (US$ 700) for HHD. In the fully adjusted models, apart from history of CVD event (β = - 0.429; 95% confidence interval - 0.705, - 0.153) that predicted lower costs in patients with IHD, having of diabetes mellitus predicted higher costs in patients with IHD (β = 0.435; 0.098, 0.772), ischaemic stroke (β = 0.188; 0.052, 0.324) and HHD (β = 0.229; 0.080, 0.378). This study reveals substantial economic burden due to CVD in Cameroon. Diabetes mellitus was a consistent driver of elevated costs across the CVDs. There is urgent need to invest in cost-effective primary prevention strategies in order to reduce the incidence of CVD and consequent economic burden on a health system already laden with the impact of communicable diseases.

hyperglycemic emergencies (diabetic ketoacidosis and hyperglycemic hyperosmolar state) are the most common serious acute metabolic complications of diabetes which result in significant morbidity and mortality. There is paucity of data on hyperglycemic emergencies in Cameroon. The objective of this study was to investigate the precipitants and outcomes of patients admitted for hyperglycemic emergencies in the Buea Regional Hospital in the South West Region of Cameroon. in this retrospective study the medical records of patients admitted for hyperglycemic emergencies between 2013 and 2016 in the medical unit of the Buea Regional Hospital were reviewed. We extracted data on demographic characteristics, admission clinical characteristics, precipitants, and treatment outcomes. Logistic regression was used to determine predictors of mortality. data were available for 60 patients (51.7% females) admitted for hyperglycemic emergencies. The mean age was 55.2±16.3 (range 18-86). Overall there were 51 (85%) cases of hyperosmolar hyperglycemic state. Twenty six (43.3%) of the patients had hypertension. The most common precipitants of hyperglycemic emergencies were infections (41.7%), newly diagnosed diabetes (33.3%) and non-adherence to medications (33.3%). Mean admission blood glucose was 574mg/dl±70.0mg/dl. The median length of hospital stay was 6 days. Overall case fatality rate was 21.7%. Six (46.2%) deaths were related to infections. Predictors of mortality were a Glasgow coma score <13(p<0.001), a diastolic blood pressure <60 mmHg (p=0.034) and a heart rate >90(0.057) on admission. admission for hyperglycemic emergencies in this semi-urban hospital is associated with abnormally high case fatality. Infections, newly diagnosed diabetes and non-adherence to medications are the commonest precipitants of hyperglycemic emergencies. Public health measures to reduce morbidity and mortality from hyperglycemic crisis are urgently needed.

To evaluate health-related quality of life (HRQoL) and its determinants in chronic low back pain (CLBP) patients in Cameroon. Observational cross-sectional study. Tertiary hospital. There were 150 eligible adults with low back pain of at least 12 weeks who provided informed consent. Of these, 136 with complete questionnaires were analysed. HRQoL was measured using the WHO Quality of Life questionnaire (WHOQOL-BREF). Outcome measures included its four domain (physical health, psychological, social relationships and environmental) scores and two independent scores for overall quality of life (OQOL) and general health satisfaction (GH). Participants had a median age of 52 years, and median pain duration of 33 (IQR: 69) months. The median OQOL score was 50 (IQR: 25). After multivariable adjustment, tertiary education (β=11.43, 95% CI 3.12 to 19.75), age (β=0.49, 95% CI 0.12 to 0.87) and being a student (β=23.07, 95% CI 0.28 to 45.86) contributed to better OQOL. Age (β=0.57, 95% CI 0.10 to 1.04) and physical-type employment (β=-14.57, 95% CI -25.83 to -3.31) affected GH. Smoking (β=-20.49, 95% CI -35.49 to -5.48) and radiological anomalies (β=-7.57, 95% CI -14.64 to -0.49) affected the physical health domain, while disability (β=-0.67, 95% CI -1.14 to -0.20) and duration of pain (β=-0.13, 95% CI -0.20 to -0.05) affected the psychological domain. Income (β=14.94, 95% CI 4.06 to 25.81) affected the social domain, while education (β=9.96, 95% CI 1.41 to 18.50) and disability (β=-0.75, 95% CI -1.26 to -0.24) affected the environmental domain. Our findings suggest that CLBP affects HRQoL and multiple socioeconomic and clinical factors influence its impact on different domains of HRQoL. Multipronged management programmes, especially those that reduce disability, could improve HRQoL in patients with CLBP.

This scoping review sought to summarize available data on the prevalence, associated factors, etiology, comorbidities, treatment, cost and mortality of chronic kidney disease (CKD) in Cameroon. We searched PubMed, Scopus and African Journals Online from database inception to 31 March, 2020 to identify all studies published on the prevalence, associated factors, etiology, comorbidities, treatment, cost and mortality of CKD in Cameroon. Thirty studies were included. The prevalence of CKD varied from 3 to 14.1 and 10.0%-14.2% in rural and urban areas, respectively. The prevalence of CKD in patients with hypertension, diabetes mellitus, and human immunodeficiency virus was 12.4-50.0, 18.5%, and 3.0-47.2%, respectively. Hypertension (22.3-59.1%), chronic glomerulonephritis (15.8-56.2%), and diabetes mellitus (15.8-56.2%) were the most common causes of CKD. The cause was unknown in 13.5-17.0% of the cases. Advanced age, hypertension, diabetes mellitus, and obesity were frequent associated factors. Hemodialysis was the main treatment modality in patients with End Stage Renal Disease (ESRD). The monthly cost of management of non-dialyzed CKD was 163 US dollars. The one-year mortality rate of ESRD was 26.8-38.6%. Chronic kidney disease affects about one in 10 adults in the general population in Cameroon. Patients with hypertension, diabetes mellitus, and human immunodeficiency virus bear the greatest burden of CKD in Cameroon. Advanced age, hypertension, diabetes mellitus, and obesity are major factors associated with CKD. Chronic kidney disease in Cameroon is associated with high morbidity and mortality and huge economic cost on the patient.

Hypertension is the leading risk factor for global disease burden. Self-management of high blood pressure (BP) through self-monitoring and self-titration of medications, has proved to be one successful and cost-effective tool to achieve better BP control in many high-income countries but not much is known about its potential in low- and middle-income countries (LMICs). We used semi-structured questionnaires and focus groups in three LMICs; Peru, Cameroon and Malawi to examine perceptions and attitudes of patients diagnosed with essential hypertension towards living with hypertension, BP measurement and treatment, patient-physician relationship and opinions about self-management of high blood pressure. Results in all three countries were comparable. Patients showed varied levels of health literacy related to hypertension. BP measurement habits were mostly affected by resources available and caregiver support. Treatment and adherence to it were primarily affected by cost. Most patients were welcoming of the idea of self-management but skeptical about the ability to do self-monitoring accurately and the safety involving self-titration of medications.

Anaemia, especially in children aged <5 years, is a global health problem disproportionately affecting populations in low-income and middle-income countries. It is associated with high disability and death rates and has a negative effect on development. This study seeks to evaluate the prevalence and determinants of anaemia in children aged 6-59 months residing in Africa. This protocol was prepared using the 2015 Preferred Reporting Items for Systematic Reviews and Meta-analyses for Protocols guidelines. Relevant citations will be identified by searching EMBASE, Web of Science, PubMed, Global Medicus Index and African Journals Online from inception to 30 September 2019 with no language restrictions. Two authors will independently screen and select eligible studies for the review. Random-effect meta-analytic methods will be used to pool study-specific estimates and heterogeneity will be assessed and quantified using the χ test on Cochrane's Q and I statistics, respectively. Publication bias will be evaluated using funnel plots and Egger's test. Subgroup analysis and multiple meta-regression using backward elimination will be performed to investigate sources of substantial heterogeneity. No ethical approval is required for this study as it is based on already published data. The findings of the review will be published in a peer-reviewed journal and presented at conferences.

More than 80% of premature deaths due to cardiovascular disease (CVD) occur in low- and middle-income countries. However, access to, and affordability of medications remain a challenge in these countries. To assess the availability, cost and affordability of essential cardiovascular medicines in the South West region of Cameroon. In an audit of 63 medicine outlets, twenty-six essential medicines were surveyed using the World Health Organisation (WHO) /Health Action International methodology. Availability, costs and the ratio of the median price to the international reference price were evaluated in public, confessional, private facility medicine outlets, and community pharmacies. Affordability was assessed by calculating the number of days' wages it will cost the lowest-paid unskilled government worker to purchase a month worth of chronic treatment. Availability ranged from 25.3% (public facility outlets) to 49.2% (community pharmacies) for all medicines. This was higher in urban and semi-urban compared to rural outlets. Cost of medicines was highest in community pharmacies and lowest in public facility outlets. Aspirin, digoxin, furosemide, hydrochlorothiazide and nifedipine were affordable (cost a day's wage or less). Medicines for heart failure and dyslipidaemia (beta blockers, angiotensin converting enzyme inhibitors and statins) required 2-5 days and 6-13 days wages respectively for one month of chronic treatment. Overall availability of CVD essential medicines was lower than WHO recommendations, and medicines were largely unaffordable. While primary prevention is pivotal, improving availability and affordability of medicines especially for public facilities would provide additional benefit in curbing the CVD burden.

Ventricular noncompaction or hypertrabeculation is rare and unclassified cardiomyopathy that mostly affects the left ventricle. We report the case of biventricular hypertrabeculation in a 54-year-old woman who presented with congestive heart failure de novo associated with arrhythmia in a low-income setting. We also discussed the therapeutic challenges.

several international guidelines are available on drug treatment for hypertension, but the control of hypertension remains very poor in sub-Saharan Africa (SSA). We investigated the commonly prescribed antihypertensive drugs and their association with blood pressure (BP) control in adult Cameroonians. we consecutively recruited hypertensive outpatients attending the Buea and Limbe Regional Hospitals (southwest region of Cameroon). Controlled BP was defined as BP < 140/90mmHg in hypertensive patients aged 60 years or younger, diabetics or patients with chronic kidney disease or a BP < 150/90mmHg in non-diabetic hypertensive patients older than 60 years of age (JNC8). of the 408 participants included (mean age 61.1 years), 67% were female. The median duration of hypertension was 6 years and the median duration of the current treatment was 22 weeks. Commonly prescribed antihypertensives were calcium channel blockers (CCB, 35.1%), thiazide/thiazide-like diuretics (TD/TLD, 26.1%) and angiotensin-converting enzyme inhibitors (ACEI, 19.5%). The median monthly cost of antihypertensive was 10279.6 CFA (approximately equal to US$ 172). Seventy percent (70%) of participants were receiving at least 2 drugs, with ACEI+TD/TLD, CCB+TD/TLD, and ACEI+CCB+TD/TLD being the most frequent combination. The rate of BP control was 52% overall, and 60% in participants on monotherapy. CCBs were the most prescribed single antihypertensive drugs in this setting while ACEI+TD/TLD was the most common combination. About half of patients were at target BP control levels Improving availability and affordability of these medications may improve hypertension management and control.

Plaque-type psoriasis is a major dermatosis with significant effects on quality of life. Case complexity is often high in low-resourced settings such as in Africa where the incidence has been on the rise. Despite major advancements and newer therapeutic modalities over the last decade, an insight into the real-life, day to day challenges in low resourced settings reveal an interplay between the difficulty in obtaining these drugs and use of alternative traditional indigenous agents. We report the case of a 50 year old immunocompetent male who presented with chronic and extensive well demarcated plaques covered with silver-white scales occupying about 61% of his body surface area. Patient was however lost to follow up for about 8 months during which time, the lesions responded to some unknown homemade indigenous medications which was preferred to a systemic medication. Paramount importance on proper counselling and the need to retain patients in care is warranted by physicians and allied health personnel. Also, incentives aimed at subsidizing the newer systemic agents for patients in low resourced cohorts will go a long way to combat this multi-faceted disorder which is often unrecognized and under diagnosed.

Non-Hodgkin's lymphoma is reportedly common in Africa; however, there is limited data on renal involvement. Acute kidney injury only at presentation is rare for lymphoproliferative malignancies. A 7-year old presented to our facility with a 2-week history of progressive abdominal distension and pain, examination revealed anasarca and hypertension. On further evaluation, there were bilateral nephromegaly, acute kidney injury (AKI) and cytomorphological findings suggestive of lymphoma. Patient management was mostly supportive, and evolution was unfavourable leading to his demise. We discuss diagnostic and therapeutic challenges due to unavailability of state-of-the-art facilities in resource-constrained settings.

Burnout syndrome has been shown to mediate the pathway between job stress and depression. This study aims to assess the relationship between the various components of burnout syndrome and depression; and to determine the contribution of other sociodemographic variables to depression among medical students in Cameroon. A cross-sectional study. Three of the five medical schools in Cameroon with students in both preclinical and clinical levels of studies. The study included 413 consenting medical students. Data were collected via a printed self-administered questionnaire. The primary outcome-depression was assessed using the Patient Health Questionnaire-9 (PHQ-9). Burnout was assessed using the Oldenburg Burnout Inventory. Multivariable linear regression was used to identify independent correlates of depression. The overall prevalence of depression (PHQ-9 >4) and major depressive disorder (PHQ-9 >9) in these students was 66.34% and 23.00%, respectively. After multivariable linear regression analysis, four variables-total OLBI (beta=0.32; 95% CI 0.22 to 0.42; p<0.001); number of children (beta=-2.26; 95% CI -3.70 to -0.81; p=0.002); occurrence of a life-changing crises (beta=1.29; 95% CI 0.13 to 2.45; p=0.029) and presence of a chronic illness (beta=3.19; 95% CI 0.96 to 5.42; p=0.005) significantly predicted depression in these students and explained 32.4% of the variance (R=32.4, F[14, 204]=6.98, p<0.001). The emotional exhaustion component (R=17.4, F[1, 411]=86.39, p<0.001) explained more of the variance in depression than the disengagement component (R=6.1, F[1, 411]=26.76, p<0.001) of burnout syndrome. The prevalence of depression among medical students in Cameroon is high. It is important that correlates of depression are identified early in medical students to limit progress to depression.

To assess the potential impact of reduction in salt intake on the burden of cardiovascular disease (CVD) and premature mortality in Cameroon. Using a multicohort proportional multistate life table model with Markov process, we modelled the impact of WHO's recommended 30% relative reduction in population-wide sodium intake on the CVD burden for Cameroonian adults alive in 2016. Deterministic and probabilistic sensitivity analyses were conducted and used to quantify uncertainty. Over the lifetime, incidence is predicted to decrease by 5.2% (95% uncertainty interval (UI) 4.6 to 5.7) for ischaemic heart disease (IHD), 6.6% (95% UI 5.9 to 7.4) for haemorrhagic strokes, 4.8% (95% UI 4.2 to 5.4) for ischaemic strokes and 12.9% (95% UI 12.4 to 13.5) for hypertensive heart disease (HHD). Mortality over the lifetime is projected to reduce by 5.1% (95% UI 4.5 to 5.6) for IHD, by 6.9% (95% UI 6.1 to 7.7) for haemorrhagic stroke, by 4.5% (95% UI 4.0 to 5.1) for ischaemic stroke and by 13.3% (95% UI 12.9 to 13.7) for HHD. About 776 400 (95% UI 712 600 to 841 200) health-adjusted life years could be gained, and life expectancy might increase by 0.23 years and 0.20 years for men and women, respectively. A projected 16.8% change (reduction) between 2016 and 2030 in probability of premature mortality due to CVD would occur if population salt reduction recommended by WHO is attained. Achieving the 30% reduction in sodium intake recommended by WHO could considerably decrease the burden of CVD. Targeting blood pressure via decreasing population salt intake could translate in significant reductions in premature CVD mortality in Cameroon by 2030.

Heart failure (HF) remains a major non-communicable disease in sub-Saharan Africa (SSA) associated with high rates of readmission, mortality and loss of economic productivity as it affects mostly young and economically active adults. Atrial fibrillation (AFib) is a major determinant of mortality among patients with HF in SSA. Meanwhile, the use of anti-arrhythmic medications in the region remains unacceptably low. This review aims to evaluate the prevalence and incidence of AFib in adult patients with HF in SSA, and the all-cause mortality rate among patients with HF and AFib. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Protocols 2015 statement was used to prepare this protocol. All eligible studies from database inception to December, 31 2018 in MEDLINE, Embase, Google Scholar, Web of science and Africa-specific databases (AFROLIB, African Index Medicus and African Journals Online) will be included without language restrictions. The process of study screening, selection, data extraction and assessment of risk of bias will be conducted independently by two reviewers. Disagreements will be arbitrated by a third reviewer. Study-specific estimates will be pooled using random-effect meta-analysis and summary measures obtained will be presented in forest plots. The χ test on Cochrane's Q and the I statistics will be used to assess and quantify heterogeneity, respectively. The Egger's test and funnel plots will be used to assess publication bias. Since our review will be based on already published data, an ethical approval is not required. The findings of this review will be presented in conferences and peer-reviewed journals and shared on social media such as Researchgate, Facebook, WhatsApp and Twitter. CRD42018087564.

Almost half the world's population is infected with Helicobacter pylori (H. pylori) with the highest reported prevalence from Africa. This infection is associated with several morbid gastrointestinal conditions. Understanding the trends in seroprevalence and the factors associated with H. pylori seropositivity in dyspeptic persons can provide a guide for public health policies. This was a retrospective study, carried out with outpatient records of Wum District Hospital (WDH) from January 2012 to December 2016. We reviewed records of all patients for whom a H. pylori serology test was requested. The Cochran-Armitage trend test and multiple regression models were used to explore seroprevalence trends and predictors of seropositivity respectively. We included 451 records, 63.6% (n = 287) were female. The mean age of the study population was 40.7 years, and the overall H. pylori seroprevalence was 51.5% (95% CI: 47-56%). The use of recommended eradication regimen appears to be low and declining. On average, H. pylori seroprevalence declined by 6.8% annually (p < 0.0001). Occupational status independently predicted seropositivity, with students having lower odds of being seropositive than employed persons (aOR = 0.09, 95% CI: 0.02-0.49, p = 0.016). Despite decreasing trends, the seroprevalence of Helicobacter pylori infection is high in dyspeptic patients attending this primary care setting. Improving living standards and establishing national guidelines for eradication can possibly aid the control of this infection.

Depression is a debilitating mental health condition which affects an estimated 350 million people worldwide annually. Nurses are twice as likely to suffer from depression than professionals in other professions. This leads to a considerable loss of efficiency and productivity. We sought to determine the prevalence and predictors of depression among nurses in Cameroon. Cross-sectional analysis carried out over 6 months (January - June 2018) using nurses from public and private healthcare institutions sampled consecutively in the two English-speaking regions (North west and South west regions) of Cameroon. The nurses were handed a structured, printed, self-administered questionnaire to fill and hand in at their earliest convenience. Depression and burnout were assessed using the Patient Health Questionnaire - 9 and the Oldenburg Burnout Inventory respectively. A total of 143 nurses were recruited (mean age: 29.75 ± 6.55 years; age range: 20-55 years, 32.87% male). The overall prevalence of depression was 62.24%. Independent predictors of depression after multivariable analysis were: Number of night shifts a week (adjusted odds ratio: 1.58; value: 0.045, 95% CI; 1.01, 2.48) and Total Oldenburg Burnout Inventory score (adjusted odds ratio: 1.21, p value: 0.001; 95% CI; 1.08, 1.35). Recreational drug use was also found to perfectly predict the outcome - depression. Depression is highly prevalent among nurses in the English-speaking regions of Cameroon. Accurate predictors could prove vital for early detection and management of affected individuals. Predictors presented herein require further investigation via multicentric nationwide studies, to obtain more generalizable results.

Pulmonary hypertension (PH) has progressively moved from an orphan disease to a significant global health problem with a major disease burden in limited7hyphen;resource countries, where over 97% of patients live. The aetiologies of PH differ between high- and low-income nations, but PH due to left heart disease is credited to be the most frequent contemporary form. Although a straightforward diagnosis of PH requires the use of right heart catheterisation (RHC), access to equipment for RHC is a deterrent. Furthermore, the risk associated with RHC limits its uptake to a selection of specialised centres. Moreover, the rigour and clinical reasoning for diagnosis in clinical medicine is rapidly changing and revealing that PH can complicate a diverse range of medical conditions needing other explorations. In this article, we provide for the busy clinician, a simplified diagnostic algorithm for PH that is relevant for making a correct early diagnosis and limiting the impact of PH.

Vulva haematomas are uncommon outside the obstetric population, with an incidence of 3.7% and represent only 0.8% of all gynaecological emergencies. The first case is a 24-year-old G2P1011 referred after the failure of conservative management of a progressively increasing right labia majora swelling. Vulva incision, exploration and relieve of hematoma were done under local anaesthesia. The second case is a 17-year-old G1P1001, a student who presented with spontaneous pain and swelling of the left labia majora. The swelling was rapidly increasing, tense and tender. It spontaneously ruptured, clots were drained and the wound was packed. Vulva hematomas are not very common hence necessitating careful assessment, right diagnosis and management. Management could be conservative (analgesics, local compression) as well as surgical in cases of hemodynamic instability, rapidly increasing size of hematoma and pain intensity. Prompt surgical management reduces the risk of infection and longer hospital stays, which is important in low resource settings like ours.

Implementing electronic data collection for health research can be challenging in resource-limited settings, where electricity, Internet access, and study staff with computer training may be limited. Our team has established a successful research data infrastructure using the REDCap software at three HIV clinics and one coordinating center in Cameroon. We describe our recommended network architecture and guidance for study data teams working in similar settings.

One of the most recognized factors of maternal and neonatal outcome pertaining to the peripartum period is the duration of labour. Finding a drug that will decrease the duration of labour with no effects on mother and foetus will be welcomed. Thereby in this study we aimed to evaluate the effects of phloroglucinol on the duration of the active phase of labour. We did a single blinded placebo controlled randomised 1:1 parallel designed superiority trial between January and June 2017 in Douala general hospital. Participants greater than 18 years with singleton uncomplicated pregnancy who consented following randomisation, were administered either 80mg/8ml intravenous phloroglucinol or 8ml of sterile water when in active labour. The primary outcome was the duration of labour. Modified intention to treat analysis was done with the level of significance set at a p value of 0.05. 122 participants received the intervention. The mean total duration labour in the treatment and placebo group were 216.8 ± 38.7 and 358.5 ± 65.8 respectively (p value = 0.243). The mean duration of the active phase of labour in the treatment and placebo group were 183.0±35.6 and 316.0±52.2 respectively (p value = 0.046). The mean rate of cervical dilatation in the treatment and placebo group were 2.1 ± 0.4 and 1.3 ± 0.4 respectively (p value = 0.322). There was no difference in maternal and foetal outcomes between the two groups. Phloroglucinol shortens the duration of active phase of labour by about 2 hours (42%). It is safe to mother and baby and does not cause adverse foetal or maternal outcomes.

Hypertension is a challenging public health problem with a huge burden in the developing countries. Non-adherence to antihypertensive treatment is a big obstacle in blood pressure (BP) control and favours disease progression to complications. Our objectives were to determine the rate of non-adherence to antihypertensive pharmacotherapy, investigate factors associated with non-adherence, and to assess the association between non-adherence and BP control in the Buea Health District (BHD), Cameroon. A community-based cross-sectional study using stratified cluster sampling was conducted in the BHD from November 2013 - March 2014. Eligible consenting adult participants had their BP measured and classified using the Joint National Committee VII criteria. The Morisky medication adherence scale was used to assess adherence to BP lowering medication. Multivariable logistic regression models were used to predict non-adherence. One hundred and eighty-three participants were recruited with mean age of 55.9 years. Overall, 67.7% (95% CI: 59.8-73.6%) of participants were non-adherent to their medications. After adjusting for age, sex and other covariates, forgetfulness (aOR = 7.9, 95%CI: 3.0-20.8), multiple daily doses (aOR = 2.5, 95%CI: 1.2-5.6), financial constraints (aOR = 2.8, 95%CI: 1.1-6.9) and adverse drug effects (aOR = 7.6, 95%CI: 1.7-33.0) independently predicted non-adherence to anti-hypertensive medication. BP was controlled in only 21.3% of participants and was better in those who were adherent to medication (47.5% versus 8.2%, p <  0.01). At least two of every three hypertensive patients in the Buea Health District are non-adherent to treatment. Forgetfulness, multiple daily doses of medication, financial constraints and medication adverse effects are the major predictors of non-adherence in hypertensive patients. These factors should be targeted to improve adherence and BP control, which will contribute to stem hypertension-related morbidity and mortality.

Malaria remains a major public health problem in most tropical countries. It occasionally presents with both typical and atypical signs and symptoms. Gastrointestinal manifestations are common in malaria endemic areas but intestinal obstruction as a complication is extremely rare. We present the case of a 42-year-old black African man who presented with signs and symptoms of intestinal obstruction and was diagnosed as having Plasmodium falciparum malaria. He was successfully treated with both parenteral and orally administered antimalarial medication and the intestinal obstruction subsequently resolved. With intestinal obstruction being an important cause of morbidity and mortality, we report this case to highlight this rare complication of malaria and therefore increase physicians' awareness and prompt diagnosis and management.

home blood pressure measurement (HBPM) is not entirely capable of replacing ambulatory blood pressure (BP) measurement (ABPM), but is superior to office blood pressure measurement (OBPM). Although availability, cost, energy and lack of training are potential limitations for a wide use of HBPM in Sub-Saharan Africa (SSA), the method may add value for assessing efficacy and compliance in specific populations. We assessed the agreement between HBPM and ABPM in chronic kidney disease (CKD) patients in Douala, Cameroon. from March to August 2014, we conducted a cross sectional study in non-dialyzed CKD patients with hypertension. Using the same devices and methods, the mean of nine office and eighteen home (during three consecutive days) blood pressure readings were recorded. Each patient similarly had a 24-hour ABPM. Kappa statistic was used to assess qualitative agreement between measurement techniques. forty-six patients (mean age: 56.2 ± 11.4 years, 28 men) were included. The prevalence of optimal blood pressure control was 26, 28 and 32% for OBPM, HBPM and ABPM respectively. Compared with ABPM, HBPM was more effective than OBPM, for the detection of non-optimal BP control (Kappa statistic: 0.49 (95% CI: 0.36 - 0.62) vs. 0.22 (95%CI: 0.21 - 0.35); sensitivity: 60 vs 40%; specificity: 87 vs. 81%). HBPM potentially averts some proportion of BP misclassification in non-dialyzed hypertensive CKD patients in Cameroon.

Necrotizing fasciitis is a rare soft tissue infection characterized by rapid progressive necrosis with relative sparing of underlying muscles. This case is reported to highlight the emergence of multidrug resistant microbes in recent days which limits the use of empiric antibiotic therapy and necessitates early cultures and sensitivity enabling targeted antibiotic therapy. Factors that lead to antimicrobial resistance especially in sub-Saharan Africa have also been discussed. We report the case of a 52-year-old black man who was referred to our centre for the management of cellulitis and suppurating ulcers of the right leg which had progressed to a wet gangrene. Following physical examination and work-up, a diagnosis of fulminant necrotizing fasciitis of the right leg caused by multidrug resistant Proteus mirabilis and Escherichia coli was made. Despite the broad-spectrum empiric antibiotic therapy and aggressive multiple surgical debridement, necrosis progressed leading to an above-knee amputation. Necrotizing fasciitis is a surgical emergency that requires prompt diagnosis and aggressive surgical debridement in order to reduce morbidity and mortality. The emergence of multidrug resistant organisms in recent days have limited the use of empiric antibiotic therapy, necessitating early culture and sensitivity and the use of susceptibility-guided antibiotic therapy. Timely action to control the use of antibiotics in sub-Saharan Africa will reduce multidrug resistance and delay the arrival of post-antibiotics era.

Progestin-only subdermal implants are one of the most effective contraceptive methods. Anembryonic pregnancy is not reported as a possible outcome in cases of contraceptive failure of these products. We present a rare case of anembryonic pregnancy occurring in a woman with levonorgestrel-releasing implant (JADELLE®). A 31-year-old Cameroonian (black African) housewife with a JADELLE® implant for 13 months, consulted at our hospital for a 1-month history of pelvic pain, prolonged menstrual bleeding, and spotting. She had a last normal menstrual period 8 weeks 1 day prior to presentation. On examination, there was suprapubic tenderness and blood trickling from her cervix. Despite a negative qualitative urine pregnancy test, an empty intrauterine gestational sac with mean sac diameter of 28 mm was visualized on pelvic ultrasound. Dilation and curettage with suction was done and she had complete relief from symptoms. This case report highlights the possibility of anembryonic pregnancy occurring in women using the levonorgestrel-releasing subdermal implant (JADELLE®).

The Malaria Vaccine Implementation Program, coordinated by the World Health Organization, intended to initiate the roll-out of the RTS, S/AS01 malaria vaccine in 3 sub-Saharan African countries in 2018. With sub-optimal implementation, the effectiveness of this vaccine in routine clinical use could be significantly lower than its measured efficacy in randomized trials. This study had as objectives to systematically review and summarize published studies addressing the challenges faced during the implementation phase of malaria vaccination programs and randomized trials conducted in sub-Saharan Africa. The review also sought to report proposed solutions to the challenges identified. This was a systematic review of studies published between 1947 and 2017. Medline, Embase and the Cochrane library databases were searched. Of the 365 studies retrieved, 8 eligible studies reported on challenges of implementing a malaria vaccine in sub-Saharan Africa and possible solutions to these challenges. Data were abstracted from the eligible studies and a qualitative synthesis was done. The 8 studies included in the review had a total of 6189 participants and used a variety of methodologies (3 qualitative, 1 quantitative, 3 mixed method studies and 1 clinical trial review). There was an overall positive acceptance towards the new malaria vaccine (n = 6/8 studies), with a mean acceptance rate of 86.1% (95% CI: 62.0-110.2, n = 2). The main challenges to vaccine receptivity were: inadequate community engagement due to lack of information about the vaccine (n = 6), fear of the vaccine's side effects (n = 5), inefficient delivery of vaccination services to children (n = 4), and sub-optimal quality of the health services (n = 3). Main themes identified from the proposed solutions consisted of the following: using dynamic communication models and trusted sources for delivering vaccine-related health information to the communities (n = 6), community engagement at both national and district level (n = 6), implementing the new vaccine services alongside the existing health services already delivered (n = 6). Effective implementation of the malaria vaccine program requires careful consideration of the socio-cultural context of each community. The RTS, S/AS01 malaria vaccine acceptance and uptake may be significantly enhanced if caregivers' perceptions about vaccines and their importance are adequately fine-tuned. In order to achieve these, community participation and the provision of adequate information in an acceptable form via reliable communication channels seem to be imperative.

Infective endocarditis is a deadly disease if not promptly treated with antibiotics either in association with cardiac surgery or not. Cardiac complications are the most common complications seen in infective endocarditis. Heart failure remains the most common cause of mortality and the most common indication for cardiac surgery in patients with infective endocarditis which is increasingly available in resource limited settings. We report a case of native valve infective endocarditis of the aortic valve in a 27-year old female in a semi-urban setting in Cameroon complicated by severe aortic valve regurgitation and heart failure. She presented with a 2 month history of fever and a 2 weeks history of rapidly worsening shortness of breath. Emergency cardiac surgery was indicated which unfortunately could not be performed leading to the death of the patient. In spite of improvement in availability of diagnostic and therapeutic modalities for cardiovascular emergencies, affordability is still a challenge. Universal health coverage is advocated else the ravages of premature mortality from cardiovascular diseases may continue to remain unchecked in Sub-Saharan Africa.

Burnout syndrome is common amongst medical personnel. The objective of this study was to identify determinants of burnout syndrome among nurses in the north west and south west regions of Cameroon. A cross-sectional analysis during the months of January-June 2018 was carried out recruiting nurses consecutively after consent from state-owned and private hospitals in the English-speaking regions of Cameroon. Burnout was assessed using the Oldenburg Burnout Inventory (OLBI). Univariable regression analysis used to identify determinants of burnout syndrome among 143 nurses (mean age 29.75 ± 6.55 years) showed that being in a personal relationship (Beta = 2.25) significantly explained 3.8% of the variation in burnout (R = 3.8, F (1, 125) = 4.89, p = 0.029).
