Non-calcified plaque in asymptomatic patients with zero coronary artery calcium score: A systematic review and meta-analysis.

BACKGROUND: There is growing interest in understanding the coronary atherosclerotic burden in asymptomatic patients with zero coronary artery calcium score (CACS). In this population, we aimed to investigate the prevalence and severity of non-calcified coronary plaques (NCP) as detected by coronary CT angiography (CCTA), and to analyze the associated clinical predictors. METHODS: This was a systematic review with meta-analysis of studies indexed in PubMed/Medline and Web of Science from inception of the database to March 31st, 2023. Using the random-effects model, separate Forest and Galbraith plots were generated for each effect size assessed. Heterogeneity was assessed using the I2 statistics whilst Funnel plots and Egger's test were used to assess for publication bias. RESULTS: From a total of 14 studies comprising 37808 patients, we approximated the pooled summary estimates for the overall prevalence of NCP to be 10% (95%CI: 6%-13%). Similarly, the pooled prevalence of obstructive NCP was estimated at 1.1% (95%CI: 0.7%-1.5%) from a total of 10 studies involving 21531 patients. Hypertension [OR: 1.46 (95%CI:1.31-1.62)] and diabetes mellitus [OR: 1.69 (95%CI: 1.41-1.97)] were significantly associated with developing any NCP, with male gender being the strongest predictor [OR: 3.22 (95%CI: 2.17-4.27)]. CONCLUSION: There is a low burden of NCP among asymptomatic subjects with zero CACS. In a subset of this population who have clinical predictors of NCP, the addition of CCTA has a potential to provide a better insight about occult coronary atherosclerosis, however, a risk-benefit approach must be factored in prior to CCTA use given the low prevalence of NCP.

Retention in care for type 2 diabetes management in Sub-Saharan Africa: A systematic review.

OBJECTIVE: Diabetes prevalence has risen rapidly in Sub-Saharan Africa, but rates of retention in diabetes care are poorly understood. We conducted a systematic review and meta-analysis to determine rates of retention in care of persons with type 2 diabetes. METHODS: We searched MEDLINE, Global Health and CINAHL online databases for cohort studies and randomised control trials (RCTs) published up to 12 October 2021, that reported retention in or attrition from care for patients with type 2 diabetes in Sub-Saharan Africa. Retention was defined as persons diagnosed with diabetes who were alive and in care or with a known outcome, while attrition was defined as loss from care. RESULTS: From 6559 articles identified, after title and abstract screening, 209 articles underwent full text review. Forty six papers met the inclusion criteria, comprising 22,610 participants. Twenty one articles were of RCTs of which 8 trials had 1 year or more of follow-up and 25 articles were of non-randomised studies of which 19 had 12 months or more of follow-up. A total of 11 studies (5 RCTs and 6 non-randomised) were assessed to be of good quality. Sixteen RCTs were done in secondary or tertiary care settings. Their pooled retention rate (95% CI) was 80% (77%, 84%) in the control arm. Four RCTs had been done in primary care settings and their pooled retention rate (95% CI) was 53% (45%, 62%) in the control arm. The setting of one trial was unclear. For non-randomised studies, retention rates (95% CI) were 68% (62%, 75%) among 19 studies done in secondary and tertiary care settings, and 40% (33%, 49%) among the 6 studies done in primary care settings. CONCLUSION: Rates of retention in care of people living with diabetes are poor in primary care research settings.

Prevalence of microvascular and macrovascular complications of diabetes in newly diagnosed type 2 diabetes in low-and-middle-income countries: A systematic review and meta-analysis.

There is an excessive burden of diabetes complications in low-resource settings. We conducted a systematic review to determine the nature and frequency of diabetes complications in newly diagnosed with type 2 diabetes. A systematic search was performed using Medline, CINAHL and Global Health online databases from inception to July 2020. Articles reporting prevalence of microvascular or macrovascular complications within six months of type 2 diabetes diagnosis and published in English or French from low- and middle-income countries (LMICs) were eligible for analysis. Data were extracted using a standardized data extraction tool. Descriptive statistics were used to describe the prevalence of micro and macrovascular complications in newly diagnosed type 2 diabetes. Assessment of heterogeneity was conducted using the inconsistency index (I2) and Cochran-Q chi2 statistical tests. Publication bias was assessed by the Funnel plot and Egger test. A total of 3 292 records underwent title or abstract screening and 95 articles underwent full text review. Thirty-three studies describing 13 283 participants (aged 20 years and older) met the inclusion criteria. The eligible studies were from Asia (n = 24), Africa (n = 4), Oceania (n = 2), South America (n = 2) and the Caribbean (n = 1). For microvascular complications, the median prevalence (interquartile range) of retinopathy, nephropathy and neuropathy were 12% (6%-15%), 15% (7%-35%) and 16% (10%25%) respectively. For macrovascular complications, the median prevalence (interquartile range) was 10% (7%-17%) for ischaemic heart disease, 6% (1%-20%) for peripheral arterial disease and 2% (1%-4%) for stroke. There was evidence of substantial heterogeneity between studies for all outcomes (I2 > 90%. We found a high prevalence of complications in newly diagnosed type 2 diabetes in LMICs. Findings suggest that many people live with diabetes and are only diagnosed when they present with complications in LMICs. Research is needed to guide timely and effective identification of people living with diabetes in these settings.

Population-level faecal metagenomic profiling as a tool to predict antimicrobial resistance in Enterobacterales isolates causing invasive infections: An exploratory study across Cambodia, Kenya, and the UK.

BACKGROUND: Antimicrobial resistance (AMR) in Enterobacterales is a global health threat. Capacity for individual-level surveillance remains limited in many countries, whilst population-level surveillance approaches could inform empiric antibiotic treatment guidelines. METHODS: In this exploratory study, a novel approach to population-level prediction of AMR in Enterobacterales clinical isolates using metagenomic (Illumina) profiling of pooled DNA extracts from human faecal samples was developed and tested. Taxonomic and AMR gene profiles were used to derive taxonomy-adjusted population-level AMR metrics. Bayesian modelling, and model comparison based on cross-validation, were used to evaluate the capacity of each metric to predict the number of resistant Enterobacterales invasive infections at a population-level, using available bloodstream/cerebrospinal fluid infection data. FINDINGS: Population metagenomes comprised samples from 177, 157, and 156 individuals in Kenya, the UK, and Cambodia, respectively, collected between September 2014 and April 2016. Clinical data from independent populations included 910, 3356 and 197 bacterial isolates from blood/cerebrospinal fluid infections in Kenya, the UK and Cambodia, respectively (samples collected between January 2010 and May 2017). Enterobacterales were common colonisers and pathogens, and faecal taxonomic/AMR gene distributions and proportions of antimicrobial-resistant Enterobacterales infections differed by setting. A model including terms reflecting the metagenomic abundance of the commonest clinical Enterobacterales species, and of AMR genes known to either increase the minimum inhibitory concentration (MIC) or confer clinically-relevant resistance, had a higher predictive performance in determining population-level resistance in clinical Enterobacterales isolates compared to models considering only AMR gene information, only taxonomic information, or an intercept-only baseline model (difference in expected log predictive density compared to best model, estimated using leave-one-out cross-validation: intercept-only model = -223 [95% credible interval (CI): -330,-116]; model considering only AMR gene information = -186 [95% CI: -281,-91]; model considering only taxonomic information = -151 [95% CI: -232,-69]). INTERPRETATION: Whilst our findings are exploratory and require validation, intermittent metagenomics of pooled samples could represent an effective approach for AMR surveillance and to predict population-level AMR in clinical isolates, complementary to ongoing development of laboratory infrastructures processing individual samples.

Integration of non-communicable disease and HIV/AIDS management: a review of healthcare policies and plans in East Africa.

BACKGROUND: Low-income and middle-income countries are struggling to manage growing numbers of patients with chronic non-communicable diseases (NCDs), while services for patients with HIV infection are well established. There have been calls for integration of HIV and NCD services to increase efficiency and improve coverage of NCD care, although evidence of effectiveness remains unclear. In this review, we assess the extent to which National HIV and NCD policies in East Africa reflect the calls for HIV-NCD service integration. METHODS: Between April 2018 and December 2020, we searched for policies, strategies and guidelines associated with HIV and NCDs programmes in Burundi, Kenya, Rwanda, South Sudan, Tanzania and Uganda. Documents were searched manually for plans for integration of HIV and NCD services. Data were analysed qualitatively using document analysis. RESULTS: Thirty-one documents were screened, and 13 contained action plans for HIV and NCDs service integration. Integrated delivery of HIV and NCD care is recommended in high level health policies and treatment guidelines in four countries in the East African region; Kenya, Rwanda, Tanzania and Uganda, mostly relating to integrating NCD care into HIV programmes. The increasing burden of NCDs, as well as a move towards person-centred differentiated delivery of services for people living with HIV, is a factor in the recent adoption of integrated HIV and NCD service delivery plans. Both South Sudan and Burundi report a focus on building their healthcare infrastructure and improving coverage and quality of healthcare provision, with no reported plans for HIV and NCD care integration. CONCLUSION: Despite the limited evidence of effectiveness, some East African countries have already taken steps towards HIV and NCD service integration. Close monitoring and evaluation of the integrated HIV and NCD programmes is necessary to provide insight into the associated benefits and risks, and to inform future service developments.

Iron stores in pregnant women with sickle cell disease: a systematic review.

BACKGROUND: Gradual improvements in the management of sickle cell disease (SCD), have led to an increase in the number of women with SCD who reach the age of procreation. However, evidence on the iron status of pregnant women with sickle cell disease (PWSCD) remains inconclusive. We conducted the first systematic review on the prevalence, determinants and maternal/foetal outcomes of iron deficiency anaemia among PWSCD. METHODS: We searched MEDLINE, EMBASE, Global Health, Africa Index Medicus, the Cochrane library databases and reference lists of retrieved publications for studies describing the iron status of PWSCD. The literature search was done over a period of 1 month, with no language or date restrictions applied. Data were extracted on a Microsoft excel sheet. Two authors assessed all included studies for methodological quality and risk of bias. RESULTS: A total of 710 reports were identified for title and article screening. Five retained studies were conducted before or during the 90s and included 67 participants. After quality assessment, the observational studies were designated to have a "fair" quality assessment while the randomised control trial had an "unclear" quality assessment. The prevalence of iron deficiency anaemia among PWSCD varied by study design and diagnostic method. The overall prevalence ranged from 6.67-83.33%. None of the studies provided evidence on factors associated with iron deficiency anaemia and the randomized trial reported no difference in outcomes between PWSCD who had iron supplementation and those who did not. CONCLUSION: Evidence on factors associated with iron deficiency anaemia among PWSCD and maternal/foetal outcomes in PWSCD who have iron deficiency anaemia is poor. The studies included in this review suggests that iron deficiency anaemia may be highly prevalent in PWSCD but due to the very small sample sizes and varied study designs, this evidence is inconclusive. The review shows that there is a need for more studies with robust designs and adequate sample sizes to assess the disease burden of iron deficiency anaemia in PWSCD.

Oxytocin Versus Misoprostol Plus Oxytocin in the Prevention of Postpartum Hemorrhage at a Semi-Urban Hospital in sub-Saharan Africa: A Retrospective Cohort Study.

BACKGROUND: Post-partum hemorrhage (PPH) is a leading cause of maternal mortality. Its first-line of prevention often entails uterotonic drugs like oxytocin and misoprostol which constitute a core point of management in low-resource settings of sub-Saharan Africa. This study aimed to assess the effectiveness of oxytocin alone compared with oxytocin plus misoprostol in two different eras (before and after the advert of misoprostol) of a semi-urban Cameroonian hospital. METHODS: This was a retrospective cohort study carried out between January 2015 to April 2015 and between January 2016 to April 2016 on a group of parturients (group A) who received only oxytocin and another administered oxytocin and misoprostol (group B), respectively. All participants delivered at the Bamenda Regional Hospital, Cameroon. The two different periods represent the era before and after the implementation of misoprostol in the prevention of PPH in this semi-urban hospital. Socio-demographic data, clinical characteristics and details of delivery as well as risk factors for PPH were studied from obstetric records. RESULTS: We studied the obstetric records of 1778 parturients were studied; 857 in group A and 879 in group B. Their mean age was 26.3 ±5.2 years. Both groups were comparable in several baseline sociodemographic and clinical characteristics. The prevalence of PPH was 2.7% (3.4% vs 2.2%; p = 0.0744). The risk of PPH in the oxytocin only group was about 1.5 times higher than in the oxytocin plus misoprostol group. The estimated blood loss between the two groups was statistically significant (1100 ± 150 vs 800 ± 100 ml, p< 0.0001). The active management of the third stage of labor without misoprostol was the only risk factor for PPH. CONCLUSION AND GLOBAL HEALTH IMPLICATIONS: The implementation of misoprostol plus oxytocin in the prevention of PPH in this low-resource setting improved the obstetrical outcome by reducing the risk and the amount of blood loss during delivery.

Prevalence, indications and neonatal complications of caesarean deliveries in Cameroon: a systematic review and meta-analysis.

BACKGROUND: The trend of increasing caesarean deliveries in developed countries over the past three decades is now being observed in sub-Saharan African. This rise might be associated with an increase in the complications that could arise from this surgical intervention. We therefore sought to assess the prevalence, indications and complications of caesarean deliveries in Cameroon. METHODS: We systematically searched online databases: Medline; Global Health and the CINAHL from 01st January 1966 to 25th July 2019. We reviewed published cohort studies, retrospective register analysis and cross-sectional studies that described cohorts of pregnant women presenting at delivery facilities in Cameroon; and included those that had an estimate of the proportion of women who delivered by caesarean sections. RESULTS: There were 126 articles initially identified by the search and 88 articles were retained after removal of duplicates. After screening of the titles and abstracts, and full text review, we identified 16 articles describing 22 cohorts of women presenting for delivery in health facilities in Cameroon. The overall estimate for the prevalence of caesarean deliveries was 9.9% (95% CI: 7.4, 12.8%, I2 = 99.68%, χ2 = 315.9, p < 0.001). The prevalence of caesarean deliveries increased progressively from 3.4% (95% CI: 2.2, 4.8%) before the year 2000, to 9.8% (95% CI: 7.4, 12.8%) between 2000 and 2009 and 14.7% (95% CI: 8.8, 21.7%) from 2010 to 2019. The three commonest indications for caesarean deliveries were: cephalopelvic disproportion (27.5%; 95% CI: 17.5, 38.7%); previous caesarean deliveries (13.2%; 95% CI: 7.4, 20.3%) and foetal distress (11.2%; 95% CI: 4.8, 19.5%). Neonates who were born by caesarean delivery were more likely to have neonatal asphyxia when compared with neonates born from vaginal deliveries (OR: 6.5; 95% CI: 2.5, 16.5). CONCLUSION: The rates of caesarean deliveries in Cameroon falls just within the recommended 10-15% range proposed by the World Health Organisation but have however been increasing progressively in the past decades. There is a strong need to assess the various indications of caesarean deliveries in Cameroon in order to curb its associated complications.

Prevalence of adolescent deliveries and its complications in Cameroon: a systematic review and meta-analysis.

BACKGROUND: Adolescent deliveries (10-19 years) carry a high risk of adverse outcomes due to the biological and physiological immaturity of these mothers. They pose a significant health burden in Cameroon, as it is reported that a high proportion of women attending delivery services are teenagers. We therefore sought to systematically assess the prevalence of adolescent deliveries in the country and its maternal and neonatal outcomes. METHODS: This was a systematic review of literature and a meta-analysis. We searched MEDLINE, CINAHL and Global Health online databases for all studies that reported the proportion of adolescent women who presented for delivery in health facilities in Cameroon. All observational studies published up to 10th July 2019, were included. RESULTS: A total of 47 articles were identified by the search. After removal of duplicates and screening of the titles and abstracts, 11 eligible studies were retained with ten articles meeting the inclusion criteria. These ten studies finally retained reported on nine different cohorts with a total of 99,653 women. The pooled prevalence of adolescent deliveries from the nine cohorts in Cameroon was 14.4% (95% CI: 10.7-18.6%), the prevalence for early adolescent deliveries was 2.8% (95% CI: 0.4-7.2%), meanwhile that for late adolescent deliveries was 12.5% (95% CI: 6.7-19.8%). The prevalence of adolescent deliveries in urban areas - 13.1% (95% CI: 7.8-19.6%) was similar to that in semi-urban areas- 14.1% (95% CI: 6.7-23.5%). Adolescents were more likely than adults (> 19 years) to have low birth weight babies (OR: 1.8; 95% CI: 1.6, 2.1); babies born with asphyxia (OR: 1.7; 95% CI: 1.3, 2.1); babies born before term (OR: 1.5; 95% CI: 1.1, 1.9) and babies who die in the neonatal period (OR: 2.1; 95% CI: 1.2, 3.8). CONCLUSION: The prevalence of adolescent deliveries in Cameroon is high. Implementation of adolescent-friendly policies is necessary to reduce the proportion of adolescents who become pregnant in Cameroon.

Determinants of depression among nursing students in Cameroon: a cross-sectional analysis.

BACKGROUND: Nursing students are highly susceptible to depression given the heavy workload and clinical demands of the curriculum. Depression has negative impacts on their health and academic performance. This study aimed to determine the determinants of depression amongst nursing students in the English-speaking regions of Cameroon. METHODS: A cross-sectional analysis of 447 nursing students recruited from a combination of state-owned and private nursing institutions in the English-speaking regions of Cameroon from January - April 2018 was carried out. Independent correlates of depression were determined using multivariable regression analysis, with the level of significance set at 95%. RESULTS: The overall prevalence of depression (Patient Health Questionnaire - 9 > 4) and major depressive disorder (Patient Health Questionnaire - 9 > 9) in these students was 69.57 and 26.40% respectively. Independent correlates of depression were found to be: total Oldenburg Burnout Inventory score (aOR: 1.18; 95% CI: 1.11, 1.25; p value < 0.01); level of studies (aOR: 0.72; 95% CI: 0.55, 0.94; p value = 0.02) and occurrence of a life-changing crises (aOR: 2.13; 95% CI: 1.28, 3.55, p value < 0.01). CONCLUSION: The prevalence of depression amongst nursing students in Cameroon is high. Determinants proposed in this study require further assessment to facilitate early identification and management of depression in this high-risk group, in order to limit the negative effects linked with the condition.

Burnout as a predictor of depression: a cross-sectional study of the sociodemographic and clinical predictors of depression amongst nurses in Cameroon.

BACKGROUND: 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. METHODS: 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. RESULTS: 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; p 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. CONCLUSION: 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.

Prognostic models for the clinical management of malaria and its complications: a systematic review.

OBJECTIVE: Malaria infection could result in severe disease with high mortality. Prognostic models and scores predicting severity of infection, complications and mortality could help clinicians prioritise patients. We conducted a systematic review to assess the various models that have been produced to predict disease severity and mortality in patients infected with malaria. DESIGN: A systematic review. DATA SOURCES: Medline, Global health and CINAHL were searched up to 4 September 2019. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Published articles on models which used at least two points (or variables) of patient data to predict disease severity; potential development of complications (including coma or cerebral malaria; shock; acidosis; severe anaemia; acute kidney injury; hypoglycaemia; respiratory failure and sepsis) and mortality in patients with malaria infection. DATA EXTRACTION AND SYNTHESIS: Two independent reviewers extracted the data and assessed risk of bias using the Prediction model Risk Of Bias Assessment Tool. RESULTS: A total of 564 articles were screened and 24 articles were retained which described 27 models/scores of interests. Two of the articles described models predicting complications of malaria (severe anaemia in children and development of sepsis); 15 articles described original models predicting mortality in severe malaria; 3 articles described models predicting mortality in different contexts but adapted and validated to predict mortality in malaria; and 4 articles described models predicting severity of the disease. For the models predicting mortality, all the models had neurological dysfunction as a predictor; in children, half of the models contained hypoglycaemia and respiratory failure as a predictor meanwhile, six out of the nine models in adults had respiratory failure as a clinical predictor. Acidosis, renal failure and shock were also common predictors of mortality. Eighteen of the articles described models that could be applicable in real-life settings and all the articles had a high risk of bias due to lack of use of consistent and up-to-date methods of internal validation. CONCLUSION: Evidence is lacking on the generalisability of most of these models due lack of external validation. Emphasis should be placed on external validation of existing models and publication of the findings of their use in clinical settings to guide clinicians on management options depending on the priorities of their patients.

Iron stores in pregnant women with sickle cell disease: a protocol for a systematic review and meta-analysis.

INTRODUCTION: Sickle cell disease (SCD) is the most common inherited disease worldwide. The greatest disease burden is seen in sub-Saharan Africa. Early diagnosis and improved care of people living with SCD have led to an increase in the number of women with SCD reaching the reproductive age. Iron deficiency anaemia remains the most common cause of anaemia in pregnancy, affecting 51%-63% of pregnancies in Africa. However, the unavailability of guidelines on supplementation of iron in this pregnant subpopulation often leaves clinicians in a fix. We propose to conduct the first systematic review and possibly a meta-analysis on the prevalence, associated factors and maternal/fetal outcomes of iron deficiency anaemia among pregnant women with SCD. METHODS AND ANALYSIS: We will search the following electronic databases for studies on the iron status of pregnant women with SCD: PubMed, MEDLINE, EMBASE, Google Scholar, African Journals Online, African Index Medicus, Popline and the Cochrane Library. After the selection of eligible studies from the search output, review of full text, data extraction and data synthesis will be performed. Studies obtained from the review shall be evaluated for quality, risk of bias and heterogeneity. Appropriate statistical methods shall be used to pool prevalence estimates for matching studies globally and in subpopulations. This protocol has been reported as per the 2015 guidelines of the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. ETHICS AND DISSEMINATION: There is no requirement for ethical approval as the proposed study will use published data. The findings of this study will be published in a peer-reviewed journal and will be presented at conferences. TRIAL REGISTRATION NUMBER: CRD42018109803.

Grand multiparity in rural Cameroon: prevalence and adverse maternal and fetal delivery outcomes.

BACKGROUND: Grand multiparity is a major public health concern especially among developing countries and has been associated with higher risk of adverse maternal and fetal outcomes compared with women of lesser parity. There is a dearth of evidence on this subject in Cameroon, especially in the rural areas. We therefore carried out this study to document the prevalence and maternal and fetal delivery outcomes of grand multiparity in a rural Cameroonian setting. METHODS: We conducted a retrospective chart review of delivery records from two health facilities (the Oku District Hospital and Kevu Integrated Health Centre) in the Oku Health District over a period of eight years. Data was entered into and analyzed using Epi-Info version 7.0.8.3. The Chi-squared or Fisher's exact test was used to compare categorical variables. The threshold of statistical significance was set at 5%. RESULTS: A total of 1755 delivery records met our inclusion criteria. The overall prevalence of grand multiparity was 27.0%. We found no significant difference in the rate of selected maternal and fetal delivery outcomes between grand multiparous women and those with lesser parity (p-value> 0.05). However, grand multiparous women were less likely to develop second-fourth degree perineal tears compared to their counterparts with lesser parity (odds ratio = 0.3, 95% confidence interval = 0.2-0.7, p = 0.001). CONCLUSION: Our study depicts a high prevalence of grand multiparous delivery in this rural community. With the exception of severe perineal tear, grand multipara and their babies are as likely to develop adverse delivery outcomes as their counterparts with lesser parity. There is also the need to enhance existing government policies on reproductive health in rural areas.

Burnout as a correlate of depression among medical students in Cameroon: a cross-sectional study.

OBJECTIVE: 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. DESIGN: A cross-sectional study. SETTING: Three of the five medical schools in Cameroon with students in both preclinical and clinical levels of studies. PARTICIPANTS: The study included 413 consenting medical students. PRIMARY OUTCOME MEASURE: 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. RESULTS: 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 (R2=32.4, F[14, 204]=6.98, p<0.001). The emotional exhaustion component (R2=17.4, F[1, 411]=86.39, p<0.001) explained more of the variance in depression than the disengagement component (R2=6.1, F[1, 411]=26.76, p<0.001) of burnout syndrome. CONCLUSION: 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.

Adherence to antidiabetic medication and factors associated with non-adherence among patients with type-2 diabetes mellitus in two regional hospitals in Cameroon.

BACKGROUND: Diabetes mellitus is a growing cause of disease burden globally. Its management is multifaceted, and adherence to pharmacotherapy is known to play a significant role in glycaemic control. Data on medication adherence among affected patients is unknown in Cameroon. In this study, the level of adherence and factors influencing non-adherence to antidiabetic medication among patients with type-2 diabetes was assessed. METHODS: A hospital-based cross-sectional study among adult patients receiving care in the diabetic clinics of the Limbe and Bamenda Regional Hospitals in Cameroon was conducted. Medication adherence was assessed using the Medication Compliance Questionnaire (MCQ). Factors associated with non-adherence to medication were determined using basic and adjusted multivariable logistic regression models. RESULTS: A total of 195 patients with type 2 diabetes were recruited. The prevalence of non-adherence to medication was 54.4% [95% confidence interval (CI): 47.1-61.5%]. In multivariable analysis, age > 60 years (aO.R. = 0.48, 95% CI: 0.25-0.94), alcohol consumption (aO.R. = 2.13, 95% CI: 1.10-4.14) and insulin alone therapy (aO.R. = 2.85, 95% CI: 1.01-8.08) were associated with non-adherence. Patients attributed their non-adherence to forgetfulness (55.6%), lack of finances (38.2%) and disappearance of symptoms (14.2%). CONCLUSIONS: Adherence to anti-diabetic medication is poor in this study with more than half of participants being non-adherent. Urgent interventions are required to tackle this problem in combined efforts to stem this looming diabetes epidemic.

Burnout Syndrome amongst Medical Students in Cameroon: A Cross-Sectional Analysis of the Determinants in Preclinical and Clinical Students.

BACKGROUND: Due to a series of recognised psychological stressors in the traditional path of medical studies, medical students are prone to experience burnout syndrome. OBJECTIVE: This study aimed to determine the predictors of burnout syndrome amongst medical students in Cameroon. METHODS: This was a cross-sectional study which recruited 413 medical students consecutively after sampling three of the five medical schools in Cameroon using a random sequence generator. Data were collected via a printed self-administered questionnaire from consenting participants assessing burnout syndrome using the OLdenburg Burnout Inventory (OLBI). Data was analysed using Stata version 12 and p value significance was set at 95%. Multivariable linear regression was used to identify independent determinants of burnout syndrome. RESULTS: An alpha Cronbach coefficient of 0.74 showed that the OLBI assessed the same underlying construct of burnout syndrome in this population. The results of the multiple linear regression showed that five predictors explained 35.0% of the variance (R2= 35.0, F(9, 184) = 10.99, p <0.001). It was found that marital status significantly predicted burnout (Beta: 4.82, p value: 0.024), as well as relationship difficulties (Beta: 3.17, p value <0.001), cumulative GPA (Beta: -2.15, p value: 0.006), regretting the choice of medical studies (Beta: 7.85, p value <0.001), and recreational drug use (Beta: 6.99, p value: 0.005). CONCLUSION: Early detection of burnout in medical students in Cameroon could be done by identifying and addressing the potential determinants. The institution of preventive measures against burnout syndrome in medical schools in Cameroon is warranted to decrease the morbidity associated with the condition.

Integrated care for human immunodeficiency virus, diabetes and hypertension in Africa.

The rising burden from non-communicable diseases (NCDs) poses a huge challenge for health care delivery in Africa, where health systems are already struggling with the long-term care requirements for the millions of people now on antiretroviral therapy requiring regular visits to health facilities for monitoring, adherence support and drugs. The HIV chronic disease management programme is comparatively well-funded, well-organised and well-informed and offers many insights and opportunities for the expansion of NCD prevention and treatment services. Some degree of human immunodeficiency virus (HIV) and NCD service integration is essential, but how to do this without risking the HIV treatment gains is unclear. Both HIV and NCD services must expand within a resource-constrained environment and policymakers are in urgent need of evidence to guide cost-effective and acceptable changes in these health services.

Validation of Pediatric Weight Estimation Formulae in a Suburban Cameroonian Population: A Cross-sectional Study.

We assessed the accuracy of the Nelson, Best Guess and Advanced Pediatric Life Support (APLS) formulae in estimating weight in a suburban Cameroonian pediatric population, by conducting a cross-sectional study using 544 children aged 1 month to 12 years. Agreement between measured and estimated weight was poor for Nelson [concordance correlation coefficient (CCC) 0.89 (95% confidence interval (CI) 0.87-0.90)] and Best Guess [CCC 0.88 (95% CI 0.86-0.90)] formulae, and moderate for the APLS formula [CCC 0.92 (95% CI 0.90-0.93)]. On Bland-Altman analysis, all three methods had limits of agreement (APLS -42.2 to -45.6%, Best Guess -42.7 to -55.1%, Nelson -36.4 to -42.4%) above the -10 to -10% set as criteria for clinical agreement. Conclusively, the accuracy of all three formulae was clinically unacceptable in our study population, suggesting the need for studies aimed at deriving more accurate formulae adapted for use in our context.

Determinants of burnout syndrome among nurses in Cameroon.

OBJECTIVES: 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. RESULTS: 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 (R2 = 3.8, F (1, 125) = 4.89, p = 0.029).
