RESUMO

BACKGROUND: Understanding the aetiological organisms causing maternal infections is crucial to inform antibiotic treatment guidelines, but such data are scarce from Sub-Saharan Africa (SSA). We performed this systematic review and meta-analysis to address this gap. METHODS: Microbiologically confirmed maternal infection data were collected from PubMed, Embase, and African Journals online databases. The search strategy combined terms related to bacterial infection, pregnancy, postnatal period, observational studies, SSA. Exclusion criteria included colonization, asymptomatic infection, and screening studies. Pooled proportions for bacterial isolates and antimicrobial resistance (AMR) were calculated. Quality and completeness of reporting were assessed using the Newcastle-Ottawa and STROBE checklists. FINDINGS: We included 14 papers comprising data from 2,575 women from four sources (blood, urine, surgical wound and endocervical). Mixed-growth was commonly reported at 17% (95% CI: 12%-23%), E. coli from 11%(CI:10%-12%), S. aureus from 5%(CI: 5%-6%), Klebsiella spp. at 5%(CI: 4%- 5%) and Streptococcus spp. at 2%(CI: 1%-2%). We observed intra-sample and inter-sample heterogeneity between 88-92% in all meta-analyses. AMR rates were between 19% -77%, the highest with first-line beta-lactam antibiotics. Convenience sampling, and limited reporting of laboratory techniques were areas of concern. INTERPRETATION: We provide a comprehensive summary of microbial aetiology of maternal infections in SSA and demonstrate the paucity of data available for this region. We flag the need to review the current local and international empirical treatment guidelines for maternal bacterial infections in SSA because there is high prevalence of AMR among common causative bacteria. FUNDING: This research was supported by the NIHR-Professorship/NIHR300808 and the Wellcome-Strategic-award /206545/Z/17/Z. TRIAL REGISTRATION: Prospero ID CRD42021238515.

RESUMO

Severe acute coronavirus-2 (SARS-CoV-2) infection has been associated with endothelial damage, and impaired nitric oxide production, which results in arterial stiffness and increased risk of cardiovascular disease. Long COVID is a term used to describe the persistence or the development of new symptoms that can occur after an acute infection. Little is known about the association between arterial stiffness and Long COVID. An observational, cross-sectional study in which arterial stiffness was measured with pulse wave velocity (PWV) was carried out in 74 participants between 19 and 40 years old (53 with Long COVID, 21 age and gender-matched controls). Data was collected from participants between 1 and 9 months after acute COVID-19 infection using the Complior analyze unit protocol. The Long COVID group had higher carotid-radial-PWV (crPWV) than controls (10 m/s interquartile range [IQR] 8.5-11.2 m/s) versus 8.8 m/s (IQR 7.7-9.2 m/s) as was their carotid-radial-arterial stiffness index (crASI) (2.26 cm/ms (IQR 1.9-2.56 cm/ms) vs. 2.01 cm/ms (IQR 1.82-2.27 cm/ms); p < 0.05) in both. They also had more type-A waveforms, indicating increased arterial stiffening. Peripheral arterial stiffness was higher in adults with Long COVID than in controls who were never infected with SARS-CoV-2 as noted by the elevated levels of crPWV and crASI among adults with Long COVID.

RESUMO

Elevated triglycerides (TG) are a risk factor for cardiometabolic disorders. There are limited data on lipidomics profiles associated with serum triglycerides concentrations, although these could advance our understanding of the mechanisms underlying these associations. We conducted a lipidomics study of 308 Nigerians with replication in 199 Kenyans. Regression models were used to assess the association of TG with 480 lipid metabolites. Association and mediation analyses were conducted to determine the relationship among TG, metabolites, and several cardiometabolic traits. Ninety-nine metabolites were significantly associated with TG, and 91% of these associations replicated. Overrepresentation analysis identified enrichment of diacylglycerols, monoacylglycerols, diacylglycerophosphoethanolamines, monoacylglycerophosphocholines, ceramide phosphocholines, and diacylglycerophosphocholines. TG-cardiometabolic trait associations were largely mediated by TG-associated metabolites. Associations with type 2 diabetes, waist circumference, body mass index, total cholesterol, and low-density lipoprotein cholesterol concentration were independently mediated by metabolites in multiple subpathways. This lipidomics study in sub-Saharan Africans demonstrated that TG is associated with several non-TG lipids classes, including phosphatidylethanolamines, phosphatidylcholines, lysophospholipids, and plasmalogens, some of which may mediate the effect of TG as a risk factor for cardiometabolic disorders. The study identifies metabolites that are more proximal to cardiometabolic traits, which may be useful for understanding the underlying biology as well as differences in TG-trait associations across ancestries.

RESUMO

Introduction: Intimate partner violence (IPV) is a human rights violation that often involves violence against women, which appears to be the most prevalent type of abuse. IPV is a global public health issue with major human rights violations. Pregnant women's IPV needs special consideration because of the possible harm that might happen to mothers and their fetuses. The enormous global public health issue of IPV affects physical, mental, and sexual transgressions. Even though there were studies conducted on IPV among women, few studies were conducted among pregnant women in sub-Saharan African countries. Therefore, this study revealed IPV and associated factors among pregnant women from the recent Demographic and Health Survey (DHS) in sub-Saharan African countries. Methods: Multilevel logistic regression analysis used data from the recent sub-Saharan African countries DHS was carried out using this secondary data. For this study, pregnant women between the ages of 15 and 49 were included; the total sample size was 17,672. Multilevel logistic regression models were calibrated to determine the associated factors at the individual and community level with IPV, with a 95% CI and AOR. Results: The prevalence of IPV among pregnant women in 23 sub-Saharan African countries was 41.94%, with a 95% CI of 40.82 to 43.06%. Poorer and poorest [AOR = 1.92; 95% CI: (1.01, 3.67)] and [AOR = 2.01; 95% CI:(1.02, 3.92)], partner alcohol drink [AOR = 3.37;95% CI:(2.21, 5.14)], and no partner education [AOR = 2.01;95% CI:(1.12, 3.63)] were statistically associated factors with IPV among pregnant women. Conclusion: The prevalence of IPV among pregnant women in sub-Saharan African countries was high (41.94%). Low economic status, partner drinking alcohol, and partner no education were the associated factors of IPV. This finding provides clues for policymakers and other organizations concerned about women.

RESUMO

OBJECTIVE: To perform critical methodological assessments on designs, outcomes, quality and implementation limitations of studies evaluating the impact of malaria rapid diagnostic tests (mRDTs) on patient-important outcomes in sub-Saharan Africa. DESIGN: A systematic review of study methods. DATA SOURCES: MEDLINE, EMBASE, Cochrane Library, African Index Medicus and clinical trial registries were searched up to May 2022. ELIGIBILITY CRITERIA: Primary quantitative studies that compared mRDTs to alternative diagnostic tests for malaria on patient-important outcomes within sub-Sahara Africa. DATA EXTRACTION AND SYNTHESIS: Studies were sought by an information specialist and two independent reviewers screened for eligible records and extracted data using a predesigned form using Covidence. Methodological quality was assessed using the National Institutes of Health tools. Descriptive statistics and thematic analysis guided by the Supporting the Use of Research Evidence framework were used for analysis. Findings were presented narratively, graphically and by quality ratings. RESULTS: Our search yielded 4717 studies, of which we included 24 quantitative studies; (15, 62.5%) experimental, (5, 20.8%) quasi-experimental and (4, 16.7%) observational studies. Most studies (17, 70.8%) were conducted within government-owned facilities. Of the 24 included studies, (21, 87.5%) measured the therapeutic impact of mRDTs. Prescription patterns were the most reported outcome (20, 83.3%). Only (13, 54.2%) of all studies reported statistically significant findings, in which (11, 45.8%) demonstrated mRDTs' potential to reduce over-prescription of antimalarials. Most studies (17, 70.8%) were of good methodological quality; however, reporting sample size justification needs improvement. Implementation limitations reported were mostly about health system constraints, the unacceptability of the test by the patients and low trust among health providers. CONCLUSION: Impact evaluations of mRDTs in sub-Saharan Africa are mostly randomised trials measuring mRDTs' effect on therapeutic outcomes in real-life settings. Though their methodological quality remains good, process evaluations can be incorporated to assess how contextual concerns influence their interpretation and implementation.

RESUMO

Sickle cell disease (SCD) is a worldwide genetic blood disorder. Roughly 400,000 babies are born with SCD each year worldwide. More than 75% of these births occur in sub-Saharan Africa. The establishment of sustainable newborn screening NBS programs is an excellent approach to improving the health of persons living with SCD. The need to set up such programs in Africa cannot be overemphasized. However, initial implementation does not guarantee sustainability. More than 500 children with sickle cell anaemia (SCA) die every day due to lack of access to early diagnosis and related treatment. We systematically highlighted suggestions proffered so far, for the sustainability of NBS in low income, high burden countries. We searched online databases, PubMed, and Google Scholar for literature on sustainability of newborn screening (NBS) published between 2012 and 2022. Articles were included if they reported as outcome; sustainability, government participation, scaling up and expansion of NBS, improved patient enrolment in the newborn screening programe. Articles not suggesting same were excluded. Data were extracted from published reports. Primary outcome was government participation and enhanced patient enrolment in the NBS programe. Thematic content analysis was applied using inductive and deductive codes. We came up with 9 major themes. This study is registered with PROSPERO with registration number as CRD42023381821. Literature search yielded 918 articles (including manual searching). After screening, nine (9) publications were suitable for data extraction and analysis. Two more articles were added by manual searching, making a total of eleven (11) articles. The most frequently addressed core elements of sustainability in these papers were complete integration of services into national health care systems for sustainability of NBS programs in Low-income high-burden countries, funding and engagement from government partners from the very beginning of program development should be prioritized. Screening should be tailored to the local context; using DBS on HemoTypeSC could be a game changer for scaling up and expanding the newborn screening program in Sub-Saharan Africa.

RESUMO

BACKGROUND: Pregnancy-related anxiety significantly impacts maternal and fetal health in low- and middle-income countries (LMICs), including those within Sub-Saharan Africa (SSA). Most studies conducted to evaluate pregnancy-related anxiety in LMICs have utilized scales developed in high-income countries, despite significant variations in pregnancy-related anxiety due to socioeconomic and cultural contexts. This review surveyed existing literature in order to identify which scales have been used to measure pregnancy-related anxiety in SSA. METHODS: A systematic search was conducted in PubMed, Health and Psychosocial Instruments, and APA PsycNet for relevant studies published in the English language up to March 22, 2023. Eligible studies focused on anxiety in pregnant populations within SSA, using validated scales or tools. Screening followed PRIMSA guidelines, with blinded review at the abstract/title level and subsequent full-text review. Data was extracted and analyzed to identify trends and characteristics of the screening tools used. RESULTS: From 271 articles, 37 met inclusion criteria, identifying 24 different tools used to measure anxiety in pregnant women in SSA. The most common tools were the Generalized Anxiety Disorder 7-item scale (seven uses), State-Trait Anxiety Inventory (five uses), and the Self-Reporting Questionnaire 20 (five uses). Seven tools were pregnancy-specific, with only two designed specifically for SSA: the Risk Factor Assessment (RFA), and the 4-Item Screening Tool. Studies were most frequently conducted in South Africa, followed by Tanzania, Ethiopia, Nigeria, and Ghana. CONCLUSIONS: This scoping review illustrates that only two tools (the RFA and 4-item Screening Tool) were created to assess pregnancy-related anxiety specifically in SSA. This highlights the need for more culturally sensitive tools tailored to the specific contexts of pregnant populations in SSA.

RESUMO

BACKGROUND: Post-discharge malaria chemoprevention (PDMC) is an intervention aimed at reducing morbidity and mortality in patients hospitalized with severe anaemia, with its effectiveness established in several clinical trials. The aim of this study was to better understand factors that would influence the scale up of this intervention, and to identify preferences for two delivery mechanisms, facility-based or community-based. METHODS: Forty-six qualitative individual interviews were conducted in five sub-Saharan countries amongst malaria key opinion leaders and national decision makers. Findings were analysed following a thematic inductive approach. RESULTS: Half of participants were familiar with PDMC, with a satisfactory understanding of the intervention. Although PDMC was perceived as beneficial by most respondents, there was some unclarity on the target population. Both delivery approaches were perceived as valuable and potentially complementary. From an adoption perspective, relevant evidence generation, favorable policy environment, and committed funding were identified as key elements for the scale up of PDMC. CONCLUSIONS: The findings suggest that although PDMC was perceived as a relevant tool to prevent malaria, further clarification was needed in terms of the relevant patient population, delivery mechanisms, and more evidence should be generated from implementation research to ensure policy adoption and funding.

RESUMO

BACKGROUND: The newborn and infant continuum of care such as essential newborn care, early initiation and exclusive breastfeeding, and immunisation are highly recommended for improving the quality of life and survival of infants. However, newborn and infant mortality remains high across Sub-Saharan African countries. While unintended pregnancies are associated with adverse newborn and infant health outcomes, there is inconclusive evidence on whether pregnancy intention influences newborn and infant continuum of care completion. Therefore, this review aimed to pool findings reported in the literature on the association between pregnancy intention and newborn and infant health care across the continuum of care in Sub-Saharan Africa. METHODS: We searched MEDLINE Complete, EMBASE, CINAHL Complete, and Global Health databases for studies potentially eligible for this systematic review and meta-analysis. Two researchers independently screened the identified articles by abstract and title, and then full-text using Covidence. We used the Newcastle-Ottawa Scale to assess the quality of the included studies. The Cochran's Q test and I2 were executed to detect and quantify the presence of statistical heterogeneity in the studies. Meta-analysis was done for each outcome when more than one original study reported relevant data, using Stata statistical software version 18. RESULTS: Eleven studies were included from a total of 235 articles identified by the search. The odds of completing essential newborn care (pooled odds ratio: 3.04, 95% CI: 1.56, 5.90), early initiation of breastfeeding (pooled odds ratio: 1.30, 95% CI: 1.13, 1.52), exclusive breastfeeding (pooled odds ratio: 2.21, 95% CI: 1.68, 2.89), and being fully immunised (pooled odds ratio: 2.73, 95% CI: 1.16, 6.40) were higher among infants born to women with intended pregnancies as compared to women with unintended pregnancies. CONCLUSION: Intended pregnancy was positively associated with essential newborn care completion, early initiation and exclusive breastfeeding, and full immunisation of infants in SSA countries. Thus, policy-makers and stakeholders should strengthen the provision of quality family planning services to prevent unintended pregnancy. Furthermore, follow-up of women with unintended pregnancies is needed to increase women's opportunity to access essential newborn health care services that further reduce the risk of newborn and infant morbidity and mortality.

RESUMO

BACKGROUND: Although aging and being of African descent are well-known risk factors for masked uncontrolled hypertension (MUCH), data on MUCH among elderly black sub-Saharan Africans (BSSA) are limited. Furthermore, it is unclear whether the determinants of MUCH in younger individuals differ from those in the elderly. OBJECTIVE: This study aimed to determine the prevalence and risk factors associated with MUCH in both elderly and younger BSSA individuals. METHODS: In this study, 168 patients with treated hypertension were assessed for medical history, clinical examination, fundoscopy, echocardiography, and laboratory data. All patients underwent ambulatory blood pressure (BP) monitoring for 24 h. MUCH was diagnosed if the average 24-h mean BP ≥ 130/80 mmHg, the daytime mean BP ≥ 135/85 mmHg, and/or the nighttime mean BP ≥ 120/70 mmHg, despite controlled clinic BP (≤ 140/90 mmHg). Logistic regression analysis was performed to assess independent factors associated with MUCH, including elderly and younger adults separately. P-values < 0.05 were used to indicate statistical significance. RESULTS: Of the 168 patients aged 53.6 ± 11.6 years, 92 (54.8%) were men, with a sex ratio of 1.2, and, 66 (39%) were aged ≥ 60 years. The proportion of patients with MUCH (27.4% for all patients) was significantly higher (p = 0.002) among elderly patients than among younger patients (45.5% vs. 15.7%). Diabetes mellitus (adjusted odds ratio [aOR], 2.44; 95% confidence interval [CI], 1.27-4.46; p = 0.043), anemia (aOR, 3.18; 95% CI, 1.07-5.81; p = 0.043), hypertensive retinopathy (aOR, 4.50; 95% CI, 1.57-5.4; p = 0.043), and left ventricular hypertrophy (aOR, 4.48; 95% CI, 2.26-8.35; p = 0.043) were independently associated with MUCH in the elderly. In younger individuals, male gender (aOR, 2.16; 95% CI, (1.33-4.80); p = 0.029), obesity (aOR, 3.02; 95% CI, (1.26-5.32); p = 0.001), and left ventricular hypertrophy (LVH) (aOR, 3.08; 95% CI, (2.14-6.24); p = 0.019) were independently associated with MUCH were independently associated with MUCH. CONCLUSION: MUCH is more prevalent among elderly than among younger BSSA individuals. Determinants of MUCH vary by age. MUCH prevention and management strategies should be age-specific.

RESUMO

BACKGROUND: The control of schistosomiasis is particularly difficult in sub-Saharan Africa, which currently harbours 95% of this disease. The target population for preventive chemotherapy (PC) is expanded to all age group at risk of infection, thus increasing the demands of praziquantel (PZQ) tablets according to the new released guideline by World Health Organization. Due to the gap between available PZQ for PC and requirements, alternative approaches to assess endemicity of schistosomiasis in a community, are urgently needed for more quick and precise methods. We aimed to find out to which degree the infection status of snails can be used to guide chemotherapy against schistosomiasis. METHODS: We searched literature published from January 1991 to December 2022, that reported on the prevalence rates of Schistosoma mansoni, S. haematobium in the intermediate snails Biomphalaria spp. and Bulinus spp., respectively, and in humans. A random effect model for meta-analyses was used to calculate the pooled prevalence estimate (PPE), with heterogeneity assessed using I-squared statistic (I2), with correlation and regression analysis for the exploration of the relationship between human S. mansoni and S. haematobium infections and that in their specific intermediate hosts. RESULTS: Forty-seven publications comprising 59 field investigations were included. The pooled PPE of schistosomiasis, schistosomiasis mansoni and schistosomiasis haematobium in humans were 27.5% [95% confidence interval (CI): 24.0-31.1%], 25.6% (95% CI: 19.9-31.3%), and 28.8% (95% CI: 23.4-34.3%), respectively. The snails showed an overall infection rate of 8.6% (95% CI: 7.7-9.4%), with 12.1% (95% CI: 9.9-14.2%) in the Biomphalaria spp. snails and 6.9% (95% CI: 5.7-8.1%) in the Bulinus spp. snails. The correlation coefficient was 0.3 (95% CI: 0.01-0.5%, P < 0.05) indicating that the two variables, i.e. all intermediate host snails on the one hand and the human host on the other, were positively correlated. CONCLUSIONS: The prevalence rate of S. mansoni and S. haematobium is still high in endemic areas. Given the significant, positive correlation between the prevalence of schistosomes in humans and the intermediate snail hosts, more attention should be paid to programme integration of snail surveillance in future.

RESUMO

Little is known about Voluntary Assisted Partner Notification (VAPN) in groups in sub-Saharan Africa that experience marginalisation, and whether its use is suitable for referral to HIV care pathways. We conducted semi-structured in-depth interviews with purposively selected medical and health professionals (N = 15) regarding their perspectives and experiences with VAPN policy and its implementation. Data were analysed following a Reflexive Thematic Analysis approach. Respondents highlighted the flexibility in VAPN policy implementation and described adjustments made by health workers. Women were seen as vulnerable and lacked access to support against gender-based violence. Men who have sex with men could face exclusion from important social networks. Age-appropriate VAPN assistance was also considered unavailable for sexually active children. Embedding understandings of identity, belonging, and safety into VAPN could address individual priorities and needs. Community support networks, tailored care for children, and family-orientated approaches to HIV notification may overcome issues relating to vulnerability and marginalisation.

RESUMO

INTRODUCTION: Men's participation is imperative for improving antenatal care (ANC) access and mother and child health outcomes in sub-Saharan Africa (SSA). Research looking at improving men's participation in ANC often focuses on their instrumental and psychosocial roles and on biomedical ANC systems. There is limited understanding of how context-specific cultural experiences of fatherhood influence men's participation in ANC within broader communal support networks and across different ANC systems in SSA. Against this background, and to understand how local communities in SSA conceive men's participation in ANC, a scoping review will be undertaken to synthesise existing literature around local cultural experiences of fatherhood and men's participation in ANC in rural settings in SSA. METHODS AND ANALYSIS: The classical scoping review methodology developed by Arksey and O'Malley will be used to conduct the scoping review described above. Empirical studies published between 1 January 2000 and 31 August 2024 will be systematically searched for in key online databases (eg, PubMed/MEDLINE, CINAHL, EMBASE, PsycINFO, Cochrane Library, African Index Medicus, African Journals Online) and grey literature (eg, reports from key organisations like UNICEF and the WHO). Literature reviews, personal opinion articles and theoretical or conceptual articles that do not systematically analyse data, and non-English texts, will be excluded. Data will be extracted from the included texts in the form of study characteristics, which will be analysed using descriptive statistics, and key issues to be analysed thematically. ETHICS AND DISSEMINATION: No ethical approvals are needed for this scoping review since data will be abstracted from already-published literature and no additional data will be collected. The findings will be shared with policymakers, practitioners, researchers, students and local communities through peer-reviewed journal publication(s), conference presentations, public lectures and policy-focused stakeholder and community meetings in and outside SSA.

RESUMO

OBJECTIVE: To review HIV testing services (HTS) costs in sub-Saharan Africa. DESIGN: A systematic literature review of studies published from January 2006 to October 2020. METHODS: We searched ten electronic databases for studies that reported estimates for cost per person tested ($pptested) and cost per HIV-positive person identified ($ppositive) in sub-Saharan Africa. We explored variations in incremental cost estimates by testing modality (health facility-based, home-based, mobile-service, self-testing, campaign-style, and stand-alone), by primary or secondary/index HTS, and by population (general population, people living with HIV, antenatal care male partner, antenatal care/postnatal women and key populations). All costs are presented in 2019US$. RESULTS: Sixty-five studies reported 167 cost estimates. Most reported only $pptested (90%), while (10%) reported the $ppositive. Costs were highly skewed. The lowest mean $pptested was self-testing at $12.75 (median = $11.50); primary testing at $16.63 (median = $10.68); in the general population, $14.06 (median = $10.13). The highest costs were in campaign-style at $27.64 (median = $26.70), secondary/index testing at $27.52 (median = $15.85), and antenatal male partner at $47.94 (median = $55.19). Incremental $ppositive was lowest for home-based at $297.09 (median = $246.75); primary testing $352.31 (median = $157.03); in the general population, $262.89 (median: $140.13). CONCLUSION: While many studies reported the incremental costs of different HIV testing modalities, few presented full costs. Although the $pptested estimates varied widely, the costs for stand-alone, health facility, home-based, and mobile services were comparable, while substantially higher for campaign-style HTS and the lowest for HIV self-testing. Our review informs policymakers of the affordability of various HTS to ensure universal access to HIV testing.

RESUMO

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.

RESUMO

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. CONCLUSION: 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.

RESUMO

Introduction: 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. Methods: 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. Results: 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. Discussion: 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.

RESUMO

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.

RESUMO

INTRODUCTION: 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.
