BACKGROUND: Recent outbreaks of Ebola virus disease (EVD) and Marburg virus disease (MVD) in sub-Saharan Africa illustrate the need to better understand animal reservoirs, burden of disease, and human transmission of filoviruses. This protocol outlines a systematic literature review to assess the prevalence of filoviruses that infect humans in sub-Saharan Africa. A secondary aim is to qualitatively describe and evaluate the assays used to assess prevalence.
METHODS: The data sources for this systematic review include PubMed, Embase, and Web of Science. Titles, abstracts, and full texts will be reviewed for inclusion by a primary reviewer and then by a team of secondary reviewers, and data will be extracted using a pre-specified and piloted data extraction form. The review will include human cross-sectional studies, cohort studies, and randomized controlled trials conducted in sub-Saharan Africa up until March 13, 2024 that have been published in peer-reviewed scientific journals, with no language restrictions. Prevalence will be stratified by pathogen, population, assay, and sampling methodology and presented in forest plots with estimated prevalence and 95% confidence intervals. If there are enough studies within a stratum, I2 statistics will be calculated (using R statistical software), and data will be pooled if heterogeneity is low. In addition, assays used to detect infection will be evaluated. All studies included in the review will be assessed for quality and risk of bias using the JBI Prevalence Critical Appraisal Tool and for certainty using the GRADE certainty ratings.
CONCLUSIONS: Accurately measuring the rate of exposure to filoviruses infecting humans in sub-Saharan Africa using prevalence provides an essential understanding of natural history, transmission, and the role of subclinical infection. This systematic review will identify research gaps and provide directions for future research seeking to improve our understanding of filovirus infections. Understanding the natural history, transmission, and the role of subclinical infection is critical for predicting the impact of an intervention on disease burden.
BACKGROUND: In accordance with the guidelines outlined in the PRISMA-P methodology, this protocol was registered with PROSPERO on April 7, 2023 (ID: CRD42023415358).

UNASSIGNED: The objective of the scoping review will be to understand and describe risk factors associated with surgical site infection (SSI) in an orthopaedic surgery population in Sub-Saharan Africa and South Africa. This paper describes the protocol that will be used for the scoping review.
UNASSIGNED: A comprehensive literature search will be conducted using MEDLINE (PubMed), CINAHL (EBSCO), Embase and Cochrane Libraries to identify articles meeting the inclusion criteria, including both published and grey literature, in order to provide a broad overview of the reported risk factors associated with patients who have undergone an orthopaedic surgery with an outcome of SSI within 90 days of a procedure. Additional studies will be sourced by exploring the reference list of included eligible studies. By using a combination of the Population, Exposure, Outcome framework, terms and synonyms related to each category, in different variations, along with Boolean operators (AND, OR, NOT) in the search strategy, identified comprehensive and relevant literature for the scoping review.
UNASSIGNED: It is anticipated the results will provide a baseline of risk factors that will inform the development of a risk assessment tool for clinical use.
UNASSIGNED: This protocol will inform the development of a scoping review to describe factors associated with SSIs following orthopaedic surgery in Sub-Saharan Africa and South Africa.

BACKGROUND: Human Immunodeficiency Virus (HIV) is a global health concern, causing over 35 million deaths, with 97% occurring in developing nations, particularly impacting Sub-Saharan Africa. While HIV testing is crucial for early treatment and prevention, existing research often focuses on specific groups, neglecting general adult testing rates. This study aims to identify predictors of HIV testing uptake among adults in Sub-Saharan Africa.
METHODS: Data were obtained from the official Demographic and Health Survey program database, which used a multistage cluster sampling technique to collect the survey data. In this study, a weighted sample of 283,936 adults was included from thirteen Sub-Saharan African countries. Multilevel multivariable logistic regression analysis was employed to identify predictors of HIV testing uptake. Akaike\'s information criteria guided model selection. Adjusted odds ratios and corresponding 95% confidence intervals determined significant predictor variables.
RESULTS: Among adults in Sub-Saharan African countries, the prevalence of HIV testing uptake was 65.01% [95% CI (64.84%, 65.17%)]. Influential factors included male sex [AOR: 0.51, 95% CI (0.49,0.53)], varying odds ratios across age groups (20-24 [AOR: 3.3, 95% CI (3.21, 3.46) ], 25-29 [AOR: 4.4, 95% CI (4.23, 4.65)], 30-34 [AOR: 4.6, 95%CI (4.40, 4.87)], 35-39 [AOR: 4.0, 95%CI (3.82, 4.24)], 40-44 [AOR: 3.7, 95%CI (3.50, 3.91)], 45-49 [AOR: 2.7, 95%CI (2.55, 2.87)], 50+ [AOR: 2.7, 95%CI (2.50, 2.92)]), marital status (married [AOR: 3.3, 95%CI (3.16, 3.46)], cohabiting [AOR: 3.1, 95% CI (2.91, 3.28)], widowed/separated/divorced [AOR: 3.4, 95%CI (3.22, 3.63)]), female household headship (AOR: 1.28, 95%CI (1.24, 1.33)), education levels (primary [AOR: 3.9, 95%CI (3.72, 4.07)], secondary [AOR: 5.4, 95%CI (5.16, 5.74)], higher [AOR: 8.0, 95%CI (7.27, 8.71)]), media exposure (AOR: 1.4, 95%CI (1.32, 1.43)), wealth index (middle [AOR: 1.20, 95%CI (1.17, 1.27)], richer [AOR: 1.50, 95%CI (1.45, 1.62)]), Having discriminatory attitudes towards PLWHIV [AOR: 0.4; 95% CI (0.33, 0.37)], had multiple sexual partners [AOR: 1.2; 95% CI (1.11, 1.28)], had comprehensive knowledge about HIV [AOR: 1.6; 95% CI (1.55, 1.67)], rural residence (AOR: 1.4, 95%CI (1.28, 1.45)), and lower community illiteracy (AOR: 1.4, 95%CI (1.31, 1.50)) significantly influenced HIV testing uptake in the region.
CONCLUSIONS: This study highlights the need for tailored interventions to address disparities in HIV testing uptake among adults in Sub-Saharan Africa and progress towards the achievement of 95-95-95 targets by 2030. Thus, tailored interventions addressing key factors are crucial for enhancing testing accessibility and emphasizing awareness campaigns, easy service access, and targeted education efforts to improve early diagnosis, treatment, and HIV prevention in the region.

Since its launch in 2011, 59 governments have used the World Bank\'s Systems Approach for Better Education Results (SABER) policy tool to design their national school-based health and nutrition programs. This tool guides governments to self-evaluate their education system policies against international benchmarks and identify actionable priorities to strengthen national programs. Thirty-two of the 49 countries in sub-Saharan Africa (65%) have undertaken a SABER review, and globally the approach has been adopted by 68% of the world\'s low-income countries and 54% of lower-middle-income countries. Analysis of 51 comparable SABER School Feeding surveys suggests that countries with longer established national school meals frameworks tend also to be more advanced in other policy areas, and vice versa. The SABER reviews consistently identify, perhaps predictably, that the weakest policy areas relate to program design, implementation and fiscal space. This analysis also found that the tool had an additional value in tracking the evolution of policies when implemented over several time points, and showed that policy areas become more advanced as national programs mature. These benefits of the tool are particularly relevant to the 98 countries that co-created the global School Meals Coalition in 2021. The Coalition member countries have the specific goal of enhancing coverage and support for the well-being of schoolchildren and adolescents affected by the school closures during the COVID-19 pandemic. The SABER tool has the demonstrated potential to implement, accelerate and track changes in school meals policy and, since it has been previously used by 74% (31/42) of low- and lower-middle-income countries in sub-Saharan Africa, is an already accepted element of the political economies of those countries and so has the potential to be deployed rapidly.

BACKGROUND: Stroke is the leading cause of death and disability among adults and elderly individuals worldwide. Although several primary studies have been conducted to determine the prevalence of poststroke cognitive impairment among stroke survivors in sub-Saharan Africa, these studies have presented inconsistent findings. Therefore, this study aimed to determine the pooled prevalence of poststroke cognitive impairment and identify its associated factors among stroke survivors in sub-Saharan Africa.
METHODS: The studies were retrieved from the Google Scholar, Scopus, PubMed, and Web of Science databases. A manual search of the reference lists of the included studies was performed. A random-effects DerSimonian-Laird model was used to compute the pooled prevalence of poststroke cognitive impairment among stroke survivors in sub-Saharan Africa.
RESULTS: A total of 10 primary studies with a sample size of 1,709 stroke survivors were included in the final meta-analysis. The pooled prevalence of PSCI was obtained from the 9 included studies with a sample size of 1,566. In contrast, the data regarding the associated factors were obtained from all the 10 included studies with a sample size of 1,709. The pooled prevalence of poststroke cognitive impairment among stroke survivors was 59.61% (95% CI: 46.87, 72.35); I2 = 96.47%; P < 0.001). Increased age (≥ 45 years) [AOR = 1.23, 95% CI: 1.09, 1.40], lower educational level [AOR = 4.35, 95% CI: 2.87, 6.61], poor functional recovery [AOR = 1.75, 95% CI: 1.42, 2.15], and left hemisphere stroke [AOR = 4.88, 95% CI: 2.98, 7.99] were significantly associated with poststroke cognitive impairment.
CONCLUSIONS: The pooled prevalence of poststroke cognitive impairment was considerably high among stroke survivors in sub-Saharan Africa. Increased age, lower educational level, poor functional recovery, and left hemisphere stroke were the pooled independent predictors of poststroke cognitive impairment in sub-Saharan Africa. Stakeholders should focus on empowering education and lifestyle modifications, keeping their minds engaged, staying connected with social activities and introducing rehabilitative services for stroke survivors with these identified factors to reduce the risk of developing poststroke cognitive impairment.

UNASSIGNED: Plasmodium malariae is the most common non-falciparum species in sub-Saharan Africa. Despite this, data on its genetic diversity is scarce. Therefore, we aimed to establish a P. malariae genotyping approach based on size polymorphic regions that can be easily applied in molecular epidemiological studies.
UNASSIGNED: Four potential genotyping markers, Pm02, Pm09, P. malariae thrombospondin-related anonymous protein (pmtrap), and P. malariae merozoite surface protein fragment 2 (pmmsp1 F2) were amplified via nested PCR and analysed using automated capillary gel electrophoresis.
UNASSIGNED: We observed the highest allelic diversity for pmtrap (MOI = 1.61) and pmmsp1 F2 (He = 0.81). Further applying the two markers pmtrap and pmmsp1 F2 on a different sample set of 21 P. malariae positive individuals followed up over one week, we saw a high consistency in their performance. The results show a large complexity and high dynamics of P. malariae infections in the asymptomatic Gabonese study population.
UNASSIGNED: We successfully implemented a new genotyping panel for P. malariae consisting of only two markers: pmtrap and pmmsp1 F2. It can be easily applied in other settings to investigate the genotype diversity of P. malariae populations, providing further important data on the molecular epidemiology of this parasite species.

BACKGROUND: An essential aspect of human well-being is positive sexual health outcomes. However, the issue of adverse sexual health outcomes continues to be a major public health concern, particularly for women with disabilities in sub-Saharan Africa (SSA). Therefore, this current scoping review mapped studies conducted in the last twenty-nine years on the sexual health of women with disabilities from these five dimensions: sexual activity, contraceptive use, sexual autonomy, sexual violence and risky sexual behaviour, whilst seeking to identify the current state of knowledge and address the study gaps in SSA.
METHODS: This current scoping review was informed by the methodological framework proposed by Arksey and O\'Malley. Exploratory searches were conducted in PubMed, Web of Science, African Journals Online, etc., to identify studies conducted in SSA that focus on sexual activity, contraceptive use, sexual autonomy, sexual violence and risky sexual behaviour among women with disabilities in SSA since the inception of the International Conference on Population and Development in 1994 to 30th of March 2024. This process resulted in the inclusion of seventeen (17) studies.
RESULTS: Of the 1362 identified through various databases, 34 studies were included for the full-text retrieval and screening; only 17 studies met the inclusion criteria. The eligible studies were conducted across six countries in SSA and published between 2008 and 2023. Eight studies used quantitative study type, six utilised qualitative approach, and three employed mixed-methods analysis. Two studies were conducted on sexual activity, ten were conducted on contraceptive use, four were conducted on sexual violence, and one study was conducted on risky sexual behaviour, whilst no study on sexual autonomy met the inclusion criteria.
CONCLUSIONS: This review showed that there were few or scarce studies on sexual activity, contraceptive use, sexual autonomy, sexual violence and risky sexual behaviour among women with disabilities in SSA and even where the studies were substantial (contraceptive use), the majority of the studies were conducted in a country. Future studies should consider examining dimensions of sexual health, such as sexual autonomy, sexual activity and risky sexual behaviour of women with disabilities that were not available or were scarce in the literature.
Sexual health is really important for people\'s overall well-being, and it includes aspects like how we feel socially, mentally, emotionally, and physically. In sub-Saharan Africa, especially for women with disabilities, sexual health is a big concern. So, this review looked at studies done over the last 29 years about the sexual health of women with disabilities in sub-Saharan Africa. It focused on five areas: sexual activity, contraceptive use, sexual autonomy, sexual violence, and risky sexual behaviour. Databases were searched for relevant studies and found 17 that fit the set criteria. These studies were from six countries in sub-Saharan Africa and were published between 2008 and 2023. Most of the studies were about contraceptive use, with fewer focusing on sexual activity, sexual violence, and risky behaviour. There weren\'t any eligible studies on sexual autonomy. The review concluded that there\'s not enough research on these sexual health dimensions among women with disabilities in sub-Saharan Africa, especially on sexual autonomy, and future studies should explore this further.

Irrespective of the promising opportunity to improve profit efficiency by at least 73%, microfinance institutions operating in Sub-Saharan Africa are efficient only for 27%, far below the average value. The conclusion is drawn after analyzing the profit efficiency of the microfinance institutions using the stochastic frontier approach applied to data obtained from 128 microfinance institutions operating in 34 Sub-Saharan African countries. The study results suggest the presence of uniform profit efficiency experience across time among microfinance institutions. Microfinance institutions operating in low-income countries and credit union form microfinance are economically more efficient than their counterparts. Furthermore, the profit efficiency of microfinance institutions is significantly affected by total assets, cost per loan, loan per staff, legal status, and the county\'s income group of microfinance. Notably, the profit efficiency of microfinance institutions is adversely affected by the presence of female borrowers and female loan officers suggesting that gender diversity plays a role in the efficiency of microfinance institutions. Finally, we recommend that the managing body of microfinance work more on improving labor efficiency, earning asset utilization, loan collection efficiency, women\'s involvement and the hottest technology implementation.

BACKGROUND:  Migration in Africa is increasing and driven by a variety of inter-related socio-economic, conflict and climate-related causes. Primary healthcare (PHC) migration on PHC service will be in the forefront of responding to the associated health issues.
OBJECTIVE:  This study aimed to review the literature on the effect of migration on PHC service delivery in Africa and the challenges facing migrants in accessing PHC.
METHODS:  A systematic approach (Preferred Reporting Items for Systematic Reviews and Meta-analysis extension for Scoping Reviews) was applied across six databases and grey literature from African universities (2010 to 2021). Data were extracted and analysed quantitatively and qualitatively.
RESULTS:  A total of 3628 studies were identified and 50 were included. Most studies were descriptive or used mixed methods. Publications came from 25 countries, with 52% of studies from South Africa, Uganda and Kenya. Most migrants originated from Zimbabwe, the Democratic Republic of Congo and Somalia. Population health management for migrant communities was challenging. Migration impacted PHC services through an increase in infectious diseases, mental health disorders, reproductive health issues and malnutrition. Primary healthcare services were poorly prepared for handling displaced populations in disaster situations. Access to PHC services was compromised by factors related to migrants, health services and healthcare workers.
CONCLUSIONS:  Several countries in Africa need to better prepare their PHC services and providers to handle the increasing number of migrants in the African context.Contribution: The review points to the need for a focus on policy, reducing barriers to access and upskilling primary care providers to handle diversity and complexity.
