Abstract Background Adolescent substance use continues to be a growing major public health concern in Africa. Recent studies infer an overall estimated prevalence of 42% among adolescents in sub-Saharan Africa. Unfortunately, this phenomenon is not adequately documented across many settings in the continent despite known negative health and social consequences on affected individuals and their communities. Little is known about the social context of substance use in Africa among this population. Our aim is to conduct a systematic review, exploring the determinants and associated factors that influence adolescent substance use in Africa. Methods We will search the following databases (from January 2000 onwards): PubMed, the Cochrane Library, African Journals Online (AJOL), Google Scholar, ScienceDirect and the World Health Organization (WHO) African Index Medicus. We will include population-based observational studies reporting on determinants and/or risk factors of substance use among adolescents (age 10–19 years) across Africa. Two reviewers will independently screen all citations, full-text articles and abstract data. Potential conflicts will be resolved through discussion. Study methodological quality (or bias) will be appraised using appropriate tools. If feasible, we will conduct a random-effects meta-analysis of data. We plan to conduct a meta-synthesis of qualitative studies where appropriate Discussion This review will describe the range of determinants and associated factors found to significantly influence adolescent substance use in Africa over the last two decades. Documenting this evidence is important as it can potentially inform comprehensive interventions and treatment programmes that are targeted at adolescents and their parents in these settings.

Abstract Background: Substance use among adolescents continues to be a growing major public health concern in Africa. Recent studies infer an overall estimated prevalence of 42% among adolescents in sub-Saharan Africa. Unfortunately, this phenomenon is not adequately documented across many settings in the continent despite known negative health and social consequences on affected individuals and their communities. Little is known about the social context of substance use in Africa among this population. Our aim is to conduct a systematic review to explore determinants and associated factors that influence adolescent substance use and the effects of substance use in sub-Saharan Africa.Methods: The Cochrane Library, PubMed, EMBASE, African Journals Online, Google Scholar, Scopus, Global Health, PsychINFO, Web of Science, and the World Health Organization (WHO) regional databases will be searched for population-based observational studies reporting on the prevalence of substance use of adolescents (age 10 - 19 years) across Africa. Search dates will be from January 2000 to December 2019. Data will be extracted from eligible publications, using a data extraction tool developed for this study. A random effects meta-analysis will be conducted to pool determinants and effects (at 95% confidence interval) of estimated substance abuse among adolescents. Alternative visual and statistical approaches will be adopted instead of traditional meta-analytic approaches where necessary.Discussion: This systematic review will describe the range of determinants and associated factors that have been found to significantly influence substance use in this population group over the last two decades. Additionally, the review will also describe the possible effects of substance use among adolescents. Documenting this evidence is important as it can potentially be used to inform comprehensive interventions and treatment programmes that are targeted at adolescents and their parents in these settings.Systematic review registration: registered on PROSPERO; registration number tbc.

Abstract Background Alcohol use is a challenging problem which attributes to more than 5% of the overall global burden of disease. It is more common among persons with HIV infection than the general population. Although there are separate studies regarding people with HIV/AIDS in Ethiopia, their results are highly variable and discrepant. The objectives of this study will be to evaluate the prevalence of alcohol use and to identify its associated factors among people with HIV/AIDS in Ethiopia. Methods A systematic search of electronic databases (from inception onwards) of PubMed/MEDLINE, Embase, PsycINFO, and Cochrane Library will be conducted. Moreover, grey literatures will be searched from different sources (such as Google Scholar, OpenGrey, and World Health Organization websites). Reference lists of the selected articles will also be searched manually. Observational studies (cross-sectional, case-control, cohort) reporting the prevalence of alcohol use and/or its associated factors among adults with HIV/AIDS in Ethiopia will be included. The primary outcomes will be the prevalence of alcohol use among HIV/AIDS population. Secondary outcomes will be the determinants of alcohol use described in the included studies. Two reviewers will independently screen all citations and full-text articles and extract data. The studies’ methodological quality (or bias) will be appraised using an appropriate tool. If feasible, we will conduct a random effects meta-analysis of observational data. Heterogeneity of primary studies will be assessed using the I2 test. Prevalence estimates will be stratified according to gender, age, and geographical location. Small-study effects (publication bias) also will be examined. Discussion Our systematic review and meta-analysis will prevail the pooled prevalence of alcohol use and its determinants among people with HIV/AIDS in Ethiopia. The finding of this study will be helpful to design appropriate preventive and interventional strategies for alcohol use among people with HIV/AIDS. This can have direct or indirect policy responses and clinical implications. Systematic review registration PROSPERO CRD42019132524

Hemodialysis is the most common type of treatment for end-stage renal disease (ESRD). Frailty is associated with poor outcomes such as higher mortality. ESRD patients have a higher prevalence of frailty. This systematic review and meta-analysis aimed to identify the prevalence and associated factors of frailty and examine whether it is a predictor of mortality among ESRD patients undergoing hemodialysis. Five electronic databases including PubMed, Embase, CINAHL, Web of Science, and Cochrane Library were searched for relevant studies up to 30 November 2020. A total of 752 articles were found, and seven studies with 2604 participants in total were included in the final analysis. The pooled prevalence of frailty in patients with ESRD undergoing hemodialysis was 46% (95% Confidence interval (CI) 34.2−58.3%). Advanced age, female sex, and the presence of diabetes mellitus increased the risk of frailty in ESRD patients undergoing hemodialysis. Our main finding showed that patients with frailty had a greater risk of all-cause mortality compared with those without (hazard ratio (HR): 2.02, 95% CI: 1.65−2.48). To improve ESRD patient outcomes, healthcare professionals need to assess the frailty of older ESRD patients, particularly by considering gender and comorbidities. Comprehensive frailty screening tools for ESRD patients on hemodialysis need to be developed.

Introduction Maternal depression (MD), is an overarching term for depression affecting pregnant women and mothers for up to 12 months postpartum. Because MD may have chronic and long-lasting effects, it is an important public health concern. The extent to which telemedicine may be an effective way to provide services to sufferers of MD is unknown, therefore, this review aimed to assess the available evidence. Methods We conducted a search of The Cochrane Library, PubMed/MEDLINE, PsycINFO, and EMBASE for relevant randomised controlled trials published between 2000 and 2018; we then conducted a systematic review and meta-analysis. Results We identified 10 studies for inclusion. Therapeutic strategies involved cognitive behavioural therapy (CBT), behavioural activation and other psychoeducation. Eight trials reported significant improvement in depression scores post-intervention; four studies that conducted post-intervention follow-up found that these improvements continued. However, high attrition rates and lack of blinding were common problems. Discussion This review found limited evidence supporting the delivery of CBT for the treatment of MD and anxiety using telemedicine. However, most of the evidence only studied improvements in postpartum depression, indicating that use of telemedicine to provide MD intervention is still small and an under-researched area.

Dengue virus (DENV) infection has garnered a global interest in the past few decades. Nevertheless, its epidemiology in certain developing and low-income regions remains poorly understood, due to the absence of comprehensive surveillance and reporting systems. This systematic review and meta-analysis aimed to determine the prevalence of DENV infection in the population of Sub-Saharan Africa using DENV infection markers, and to track any changes in its prevalence during the past ten years. It was conducted in accordance with the PRISMA guidelines, targeting the literature available at MEDLINE/PubMed, ScienceDirect, Cochrane library and Google Scholar. All articles published in English language between January 2010 and June 2020 were screened for eligibility. Random effects model was used to calculate the pooled prevalence of all infection markers. The Inconsistency Index (I2) was used to assess the level of heterogeneity between studies. Subgroup analysis according to country and time-frame of studies was conducted to provide possible explanations to substantial heterogeneity. The critical appraisal tool for prevalence studies designed by the Joanna Briggs Institute (JBI) was used to assess the risk of bias in all included studies. A total of 84 articles, covering 21 countries, were included in this review. Quantitative meta-analysis estimated a pooled IgG prevalence of 25% (95% CI: 21-29%, I2 = 99%), a pooled IgM prevalence of 10% (95% CI: 9-11%, I2 = 98%) and a pooled DENV RNA prevalence of 14% (95% CI: 12-16%, I2 = 99%). Evidence for possible publication bias was also found in all three meta-analyses. Subgroup analysis according to the time of sample collection was performed to closely track the changing prevalence of DENV infection markers between 2010 and 2019. This meta-analysis estimates a high prevalence of DENV infection in Sub-Saharan Africa. More cost-efficient vector control strategies should be designed and implemented in order to adapt to the low-resource nature of this region.

Abstract Background As compared to other regions of the world, Sub Saharan Africa (SSA) is the region with the highest neonatal mortality and is the region showing the least progress in the reduction of newborn death. Despite better progress made in reducing neonatal mortality, Ethiopia contributes the highest rate of neonatal death in Africa. In Ethiopia, findings from few studies were inconsistent and there is a need to systematically pool existing data to determine the impact of antenatal care on neonatal mortality among mother-neonate pairs in Ethiopia. Methods Published articles from various electronic databases such as Medline, Hinari, Pub Med, Cochrane library, the Web of Science, and Google Scholar were accessed. Also, unpublished studies from library catalogs were identified. All observational studies that were conducted on the association between antenatal care follow-up and neonatal mortality among neonates in Ethiopia were included. Data were extracted on the Microsoft Excel spreadsheet and analyzed using STATA 14.1 version. A random-effects model was used to estimate the pooled estimate with a 95% confidence interval (CI). Forest plots were used to visualize the presence of heterogeneity and estimate the pooled impact on antenatal care on neonatal mortality. The presence of publication bias was assessed by funnel plots and Egger’s statistical tests. Results Initially, a total of 345 studies were accessed. Finally, 28 full-text studies were reviewed and fourteen studies fulfilled inclusion criteria and included in the final meta-analysis. The overall pooled estimate indicates the odds of neonatal death among neonates from women with antenatal care were 65% lower than those neonates from women who had no antenatal care follow-up (OR: 0.35, 95% CI: 0.24, 0.51). Conclusions In this systematic review and meta-analysis, lack of ANC follow-up increase the probability of neonatal mortality as compared to having ANC follow-up. Thus, we will recommend for more coverages of appropriate antenatal care where risk groups can best be identified and managed.

Objective. Syphilis is one of the most imperative STIs, caused by the spirochete Treponema pallidum. During pregnancy it is associated with disastrous health outcomes in the newborn. In sub-Saharan Africa, study findings on the prevalence of syphilis among pregnant women are highly dispersed and inconsistent. The aim of the current review is to conduct a systematic review and meta-analysis of syphilis in sub-Saharan Africa among pregnant women. Design. Systematic review and meta-analysis. Data Sources. Databases including MEDLINE, PubMed, Cochrane Library, Google Scholar, and HINARI and reference lists of previous prevalence studies were systematically searched for relevant literature from January 1999 to November 2018. Results were presented in forest plot, tables, and figures. Random-effects model was used for the meta-analysis. For the purpose of this review, a case of syphilis was defined as positive treponemal or nontreponemal tests among pregnant women. Data Extraction. Our search gave a total of 262 citations from all searched databases. Of these, 44 studies fulfilling the inclusion criteria and comprising 175,546 subjects were finally included. Results. The pooled prevalence of syphilis among pregnant women in sub-Saharan Africa was 2.9% (95%CI: 2.4%-3.4%). East and Southern African regions had a higher syphilis prevalence among pregnant women (3.2%, 95% CI: 2.3%-4.2% and 3.6%, 95%CI: 2.0%-5.1%, respectively) than the sub-Saharan African pooled prevalence. The prevalence of syphilis among pregnant women in most parts of the region seemed to have decreased over the past 20 years except for the East African region. However, prevalence did not significantly differ by region and time period. Conclusion. This review showed a high prevalence of syphilis in sub-Saharan Africa among pregnant women. The evidence suggests strengthening the screening program during pregnancy as part of the care package during antenatal care visits. Programs focusing on primary prevention of syphilis in women should also be strengthened.
