"It takes more than a fellowship program": reflections on capacity strengthening for health systems research in sub-Saharan Africa.

Sub-Saharan Africa (SSA) experiences an acute dearth of well-trained and skilled researchers. This dearth constrains the region's capacity to identify and address the root causes of its poor social, health, development, and other outcomes. Building sustainable research capacity in SSA requires, among other things, locally led and run initiatives that draw on existing regional capacities as well as mutually beneficial global collaborations. This paper describes a regional research capacity strengthening initiative-the African Doctoral Dissertation Research Fellowship (ADDRF) program. This Africa-based and African-led initiative has emerged as a practical and tested platform for producing and nurturing research leaders, strengthening university-wide systems for quality research training and productivity, and building a critical mass of highly-trained African scholars and researchers. The program deploys different interventions to ensure the success of fellows. These interventions include research methods and scientific writing workshops, research and reentry support grants, post-doctoral research support and placements, as well as grants for networking and scholarly conferences attendance. Across the region, ADDRF graduates are emerging as research leaders, showing signs of becoming the next generation of world-class researchers, and supporting the transformations of their home-institutions. While the contributions of the ADDRF program to research capacity strengthening in the region are significant, the sustainability of the initiative and other research and training fellowship programs on the continent requires significant investments from local sources and, especially, governments and the private sector in Africa. The ADDRF experience demonstrates that research capacity building in Africa is possible through innovative, multifaceted interventions that support graduate students to develop different critical capacities and transferable skills and build, expand, and maintain networks that can sustain them as scholars and researchers.

Situation analysis of urogenital bilharzia in West Africa (2010-2021) and control strategies and prospects: systematic review and meta-analysis.

Schistosomes are parasitic diseases caused by flatworms (schistosomes or bilharzia), transmitted in the urine or in the faeces, and involving intermediate hosts (freshwater molluscs). Their recrudescence in endemic areas is no longer in question and remains a crucial public health problem in the world in general and in West Africa in particular. In order to eradicate bilharzia, many control strategies and policies have been implemented on both sides. The objective of this systematic literature review is to synthesize the existing evidence on control strategies implemented by West African countries. To achieve this, data were collected from PubMed, Direct Science, Web of Sciences, Google Scholar, PloS and Banque de Données de Santé Publique (BDSP), using appropriate keywords. Academic articles and theses written in French or English that evaluated the analysis of a bilharzia situation in West Africa were selected. Sixteen scientific papers were selected for the study, ten of which were used for a meta-analysis. The systematic review revealed that bilharzia is still an endemic disease in West Africa. Clearly, it continues to wreak havoc on the population, especially among school children. Rural areas are the most affected by the disease. Strategies to control bilharzia are based on preventive and curative treatment of the infection with chemotherapy and vector control of soil molluscs (host and vector of bilharzia eggs). Praziquantel is the main known antibilharzian. Also, the species most frequently found in analyses are S. haematobiumand S. mansonii. This review has allowed to evaluate the control strategies carried out and to deduce the strengths and weaknesses, in order to define the perspectives for the efficiency of the anti-bilharzia control for the eradication of bilharzia in the endemic zones of West Africa.

Postpandemic Evaluation of the Eco-Efficiency of Personal Protective Equipment Against COVID-19 in Emergency Departments: Proposal for a Mixed Methods Study.

BACKGROUND: The COVID-19 pandemic has had a profound impact on emergency department (ED) care in Canada and around the world. To prevent transmission of COVID-19, personal protective equipment (PPE) was required for all ED care providers in contact with suspected cases. With mass vaccination and improvements in several infection prevention components, our hypothesis is that the risks of transmission of COVID-19 will be significantly reduced and that current PPE use will have economic and ecological consequences that exceed its anticipated benefits. Evidence is needed to evaluate PPE use so that recommendations can ensure the clinical, economic, and environmental efficiency (ie, eco-efficiency) of its use. OBJECTIVE: To support the development of recommendations for the eco-efficient use of PPE, our research objectives are to (1) estimate the clinical effectiveness (reduced transmission, hospitalizations, mortality, and work absenteeism) of PPE against COVID-19 for health care workers; (2) estimate the financial cost of using PPE in the ED for the management of suspected or confirmed COVID-19 patients; and (3) estimate the ecological footprint of PPE use against COVID-19 in the ED. METHODS: We will conduct a mixed method study to evaluate the eco-efficiency of PPE use in the 5 EDs of the CHU de Québec-Université Laval (Québec, Canada). To achieve our goals, the project will include four phases: systematic review of the literature to assess the clinical effectiveness of PPE (objective 1; phase 1); cost estimation of PPE use in the ED using a time-driven activity-based costing method (objective 2; phase 2); ecological footprint estimation of PPE use using a life cycle assessment approach (objective 3; phase 3); and cost-consequence analysis and focus groups (integration of objectives 1 to 3; phase 4). RESULTS: The first 3 phases have started. The results of these phases will be available in 2023. Phase 4 will begin in 2023 and results will be available in 2024. CONCLUSIONS: While the benefits of PPE use are likely to diminish as health care workers' immunity increases, it is important to assess its economic and ecological impacts to develop recommendations to guide its eco-efficient use.

[Factors associated with the quality of sterilization of surgical drapes at the National Hospital University Hubert Koutoukou Maga of Cotonou]. / Facteurs associés à la qualité de la stérilisation du linge opératoire au Centre National Hospitalier Universitaire Hubert Koutoukou MAGA de Cotonou.

INTRODUCTION: The sterilization of surgical drapes plays an important role in preventing infections associated with treatments. At the CNHU-HKM, sterilization procedure for drapes encounters problems. The purpose of this study was to examine the factors associated with the quality of sterilization of surgical drapes at the CNHU-HKM. METHODS: We conducted a cross-sectional, descriptive and analytical study focusing on 20 sterile surgical drapes, 41 agents were involved in the management of drapes and 55 members of the surgical team. The probabilistic method was used for sterile surgical drapes, the non-probabilistic method for the others. Pearson's Chi-square Test and logistic regression were used to find the association, with a significant threshold and a p<0.05. RESULTS: Eighty six point forty six percent of subjects were males with an average age of 42 years. The quality of the process of sterilization of the operative drapes was not good in the two departments responsible for processing the drapes. Bacteriological analysis showed that, out of 20 sterile surgical drapes, 9 had Acinetobacter spp. a multidrug-resistant germ causing nosocomial infections. Multivariate analysis showed that professional experience (p=0.015) and quality control of the procedure (p=0.034) were statistically associated with the quality of sterilization. CONCLUSION: The presence of Acinetobacter spp. on the sterilized drapes demonstrates that sterilization of drapes at the CNHU-HKM is of poor quality. Measures strengthening the skills of providers are necessary to improve the quality of sterilization procedures.

Factors associated with noncompliance of sodium restriction in hypertensive and heart failure patients at the National Hospital of Cotonou, Benin.

INTRODUCTION: Nutritional therapy in the treatment of high blood pressure and heart failure is a real challenge in terms of compliance of sodium restriction for success of the treatment. The study aims to assess the level of patient compliance with the sodium restriction by salt consumption, prescribed by care providers and the associated factors. MATERIALS AND METHODS: Total daily salt intake was estimated in a cross-sectional study of 166 hypertensive and heart failure subjects monitored in the cardiology department of the "Centre Hospitalier Universitaire - Hubert Koutoukou Maga" (CNHU-HKM), using two 24-hour recalls combined with a food frequency questionnaire for salt-providing foods. RESULTS: Out of the study, 83.7% of patients had a daily intake above recommendations. Factors associated with the non-compliance of salt restriction were the lack of knowledge of palliative spices and herbs of salty taste (p=0.009) and the consumption of salty snack foods and salty peanuts (p=0.032). CONCLUSION: Nutritional education and support activities should be carried out to improve the salt reduction compliance for these patients.

Insulin resistance status and four-year changes in other cardiometabolic risk factors in West-African adults: the Benin study.

BACKGROUND: The association of insulin resistance (IR) with other cardiometabolic risk (CMR) factors in sub-Saharan Africans is poorly documented. This study examined the links between IR and the evolution of blood pressure (BP), glycaemia, serum lipids and abdominal obesity in the population of Benin. DESIGN: Population-based longitudinal study. METHODS: This study initially included 541 apparently healthy Beninese adults (50% women) aged 25-60 years who were randomly selected in a large city, a small town and a rural area. After a baseline survey, our subjects were followed up after 2 years, and again at 4 years. IR based on homeostasis model assessment (HOMA), blood glucose, BP, waist circumference (WC), triglycerides, total cholesterol and HDL-cholesterol were measured. Complete data at the end of the follow-up periods was available for 416 subjects. RESULTS: IR was more prevalent in women than in men (33.2% versus 17.8%) and it was generally associated with more adverse values of CMR factors, excepting BP. In controlling for baseline age, sex, WC, diet, lifestyle variables and WC changes; the relative risk (RR) of hyperglycemia over 4 years was as least 3-fold in IR subjects, compared to normal subjects. The RR of abdominal obesity was 5.3 (1.04-26.93) in IR women, compared to non-IR. The association of IR with the evolution of dyslipidemia was inconsistent, but IR tended to exacerbate low HDL-cholesterol. CONCLUSION: Over 4 years, IR exacerbated hyperglycemia in both men and women, and abdominal obesity in women, but IR did not affect blood pressure. Further research on the link found between IR and dyslipidemia, particularly low HDL-C, is needed in sub-Saharan Africa.

Lifestyle and dietary factors associated with the evolution of cardiometabolic risk over four years in West-African adults: the Benin study.

AIM: To assess in adults from Benin changes in cardiometabolic risk (CMR) using both the Framingham risk score (FRS) and metabolic syndrome (MetS) and to examine the effects of diet, and lifestyles, controlling for location and socioeconomic status. METHODS: Apparently healthy subjects (n = 541) aged 25-60 years and randomly selected in the largest city, a small town, and rural areas were included in the four-year longitudinal study. Along with CMR factors, socioeconomic, diet and lifestyle data were collected in individual interviews. A food score based on consumption frequency of four "sentinel" food groups (meat and poultry, dairy, eggs, and vegetables) was developed. Lifestyle included physical activity, alcohol and tobacco use. Education and income (proxy) were the socioeconomic variables. RESULTS: Among the subjects with four-year follow-up data (n = 416), 13.5% were at risk at baseline, showing MetS or FRS ≥ 10%. The incidence of MetS and FRS ≥ 10% during follow-up was 8.2% and 5%, respectively. CMR deteriorated in 21% of subjects. Diet and lifestyle mediated location and income effects on CMR evolution. Low food scores and inactivity increased the likelihood of CMR deterioration. CONCLUSION: Combining MetS and FRS might be appropriate for surveillance purposes in order to better capture CMR and inform preventive measures.

Four-Year Trends in Cardiometabolic Risk Factors according to Baseline Abdominal Obesity Status in West-African Adults: The Benin Study.

The study examined whether abdominal obesity (AO) according to waist circumference was associated with more unfavourable changes in other cardiometabolic risk (CMR) factors in sub-Saharan Africans. The study included 541 randomly selected and apparently healthy subjects (50% women) aged 25-60 years. Complete data at baseline, 24, and 48 months later was available in 366 subjects. AO was associated with higher CMR at baseline and over the follow-up period, except for high blood pressure. A significantly higher incidence of high ratio of total cholesterol : HDL-cholesterol (TC/HDL-C) was associated with AO. Controlling for WC changes, age, baseline diet, and lifestyles, the relative risk (RR) of low HDL-C and high TC/HDL-C was 3.2 (95% CI 1.06-9.61) and 7.4 (95% CI 2.01-25.79), respectively, in AO men; the RR was not significant in women. Over a four-year period, AO therefore appeared associated with an adverse evolution of cholesterolemia in the study population.
