Project description:BackgroundTyphoid fever incidence and complications, including intestinal perforation, have declined significantly in high-income countries, with mortality rates <1%. However, an estimated 10.9 million cases still occur annually, most in low- and middle-income countries. With the availability of a new typhoid conjugate vaccine licensed for children and recommended by the World Health Organization, understanding severe complications, including associated mortality rates, is essential to inform country-level decisions on introduction of this vaccine. This scoping review summarizes over 20 years of the literature on typhoid intestinal perforation in sub-Saharan Africa.MethodsWe searched EMBASE, PubMed, Medline, and Cochrane databases for studies reporting mortality rates due to typhoid intestinal perforation in children, under 18 years old, in sub-Saharan Africa published from January 1995 through June 2019.ResultsTwenty-four papers from six countries were included. Reported mortality rates ranged from 4.6-75%, with 16 of the 24 studies between 11 and 30%. Thirteen papers included postoperative morbidity rates, ranging from 16-100%. The most documented complications included surgical site infections, intra-abdominal abscesses, and enterocutaneous fistulas. High mortality rates can be attributed to late presentation to tertiary centers, sepsis and electrolyte abnormalities requiring preoperative resuscitation, prolonged perforation-to-surgery interval, and lack of access to critical care or an intensive care unit postoperatively.ConclusionsCurrent estimates of mortality related to typhoid intestinal perforation among children in sub-Saharan Africa remain unacceptably high. Prevention of typhoid fever is essential to reduce mortality, with the ultimate goal of a comprehensive approach that utilizes vaccination, improvements in water, sanitation, and hygiene, and greater access to surgical care.
Project description:In Africa, at least 240,000 children are born each year with sickle cell disease. Historically, in the absence of newborn screening and appropriate treatment, most such children died undiagnosed in early childhood. However, with increasing awareness of the condition and economic and epidemiologic transition, increasing numbers are surviving. Greater investments in basic and applied research in the African context, and increased sensitization or African ministries of health regarding the importance of this condition, could make a substantial difference to the lives and livelihoods of millions of people living with sickle cell disease on the continent and their families.
Project description:BackgroundEstimations show that at least one in every 3 people in the world needs rehabilitation at some point in the course of their illness or injury. Access to rehabilitation services is an essential part of the continuum of care and is integral to achieving universal health coverage. However, most of the world's population living in low- and middle-income countries, especially in the sub-Saharan African region, does not have access to adequate rehabilitation services. Wider adoption of digital solutions offers opportunities to support and enhance access to rehabilitation services in sub-Saharan Africa. A region where there is a greater burden and need for these services. There is also little published research about digital rehabilitation in sub-Saharan Africa, as it is an underexamined topic in the region.ObjectiveThis scoping review aims to provide a comprehensive picture of the current evidence of digital interventions in rehabilitation implemented in any health, social, educational, or community setting in the sub-Saharan Africa region.MethodsWe will conduct a scoping review using Arksey and O'Malley's methodological framework and follow the Joanna Briggs Institute methodology for scoping reviews. We will develop search strategies for a selected number of web-based databases, search for peer-reviewed scientific publications until September 2023, and screen the reference lists of relevant articles. We will include research articles if they describe or report the use of digital interventions in the rehabilitation of patients with any health problem or disability in sub-Saharan Africa. For selected articles, we will extract data using a customized data extraction form and use thematic analysis to compare the findings across studies.ResultsThe preliminary database search in MEDLINE (EBSCO) was completed in May 2023. The research team will conduct a search of relevant articles in the autumn. The results will be synthesized and reported under the key conceptual categories of this review, and we expect the final scoping review to be ready for submission in early 2024.ConclusionsWe expect to find gaps in the research and a lack of detailed information about digital rehabilitation interventions in sub-Saharan Africa, as well as potential areas for further study. We will identify opportunities to inform the development of digital rehabilitation interventions.International registered report identifier (irrid)PRR1-10.2196/48952.
Project description:BackgroundGlobally, adolescents are vulnerable to mental health problems, particularly those from sub-Saharan Africa (SSA) due to impoverished living conditions and a higher prevalence of chronic conditions such as HIV/AIDS in the region. The COVID-19 pandemic has further exacerbated this risk. This calls for an urgent need for evidence-based adolescent mental health interventions to reduce the risk and burden of mental health problems in SSA. The review aims to identify and characterize existing adolescent mental health interventions in SSA, as well as to evaluate their implementation strategies and effectiveness.MethodsWe systematically searched PubMed, African Index Medicus, PsycINFO, Web of Science, and CINAHL databases for relevant articles. Furthermore, we searched gray literature databases, including Think Tank search, open gray, NGO search engine, and IGO search engine for additional relevant articles. The scoping review was conducted to identify original research articles on mental health interventions among adolescents in sub-Saharan Africa published from database inception to 31 December 2021. We carried out a narrative synthesis to report our findings.ResultsOur literature search generated 4,750 studies, of which 1,141 were duplicates, 3,545 were excluded after screening, and 64 articles met the inclusion criteria. The 64 studies describe a total of 57 unique mental health interventions comprising 40,072 adolescents. The nature of these interventions was diverse, encompassing various implementation strategies such as economic-based, family strengthening, psychoeducation, interpersonal psychotherapy, Cognitive Behavioral Therapy, and resilience training, among others. Most of the interventions were selective interventions that targeted adolescents at high risk of developing mental health problems including adolescents living with HIV, war-affected adolescents, orphans, adolescents from poorer backgrounds, and survivors of sexual violence. Half of the interventions were delivered by lay persons. Sixty-two of the eligible studies examined the effectiveness of the mental health interventions, of which 55 of them reported a positive significant impact on various mental health outcomes.ConclusionsThe review findings show that there exist several diverse interventions that promote mental health among adolescents in sub-Saharan Africa. These interventions can be implemented in diverse settings including schools, communities, health facilities, and camps, and can be delivered by lay persons.
Project description:BACKGROUND:Although under-five mortality reduced globally from 93 per 1000 live births in 1990 to 39 in 2018, sub-Saharan Africa witnessed an increase from 31% in 1990 to 54% in 2018. Morbidity has been reported to contribute largely to these deaths. This study examined the factors that are associated with childhood morbidity in sub-Saharan Africa. METHODS:Demographic and Health Surveys of 31 countries in sub-Saharan Africa were used in this study. The study involved 189 069 children who had or did not have fever, cough or diarrhoea in the 2 weeks preceding the surveys. Descriptive statistics and binary logistic regression were applied in the analysis. RESULTS:About 22% of the children suffered from fever, 23% suffered from cough and 16% suffered from diarrhoea. While the odds of experiencing fever increased by 37% and 18%, respectively, for children from poorest and poorer households, children of women aged 15-24 and 25-34 years are 47% and 23%, respectively, more likely to experience diarrhoea. The probability of suffering from morbidity increased for children who are 12-23 months, of higher order birth, small in size at birth and from households with non-improved toilet facility. CONCLUSIONS:This study has shown that childhood morbidity remains a major health challenge in sub-Saharan Africa with socioeconomic, maternal, child's and environmental factors playing significant roles. Efforts at addressing this problem should consider these factors.
Project description:BackgroundMaternal and child mortality remains a major public health issue in sub-Saharan Africa (SSA), with the region having the highest under-five mortality rates, where approximately 1 in 11 children, dies before the age of 5 years. This is nearly 15 times the average in high-income countries (HICs). This scoping review is aimed at mapping evidence on the factors contributing to maternal and child mortality in SSA.MethodsThis study will be conducted using a scoping review to map existing literature on the factors contributing to maternal and child mortality in SSA. The search will comprise of peer-reviewed and grey literature, using the EBSCOhost platform. Keyword search from electronic databases such as PubMed/MEDLINE, Google Scholar, Science Direct and World Health Organization library, will be conducted. Information will be obtained from the included studies, using a data charting table. We will use NVIVO version 10 software to analyse the data, and the narrative account of the study will be presented by means of a thematic content analysis.DiscussionWe expect to find relevant literature that can help us in mapping evidence on the factors contributing to maternal and child mortality in SSA. This study results are anticipated to identify research gaps and in turn, guide the design of future primary studies.Systematic review protocol registrationOpen Science Framework registration number (DOI 10.17605/OSF.IO/XF5VN).
Project description:BackgroundImproving the design of family planning (FP) interventions is essential to advancing gender equality, maternal health outcomes, and reproductive autonomy for both men and women. While progress has been made towards applying a rights-based approach to FP interventions in sub-Saharan Africa, the ethical implications of FP interventions has been underreported and underexplored. Several ethical challenges persist related to measuring success, choice, and target population.MethodsWe conducted a scoping review to understand if and how FP interventions published between 2000 and 2020 within sub-Saharan Africa address the ethical challenges raised within the literature. We identified a total of 1,652 papers, of which 40 were included in the review.ResultsOur review demonstrated that the majority of family planning interventions in sub-Saharan Africa place a strong emphasis, on measuring success through quantitative indicators such as uptake of modern contraception methods among women, specifically those that are married and visiting healthcare centres. They also tend to bias the provision of family planning by promoting long-acting reversible contraception over other forms of contraception methods potentially undermining individuals' autonomy and choice. The interventions in our review also found most interventions exclusively target women, not recognising the importance of gender norms and social networks on women's choice in using contraception and the need for more equitable FP services.ConclusionThe results of this review highlight how FP interventions measured success through quantitative indicators that focus on uptake of modern contraception methods among women. Utilising these measures makes it difficult to break away from the legacy of FP as a tool for population control as they limit the ability to incorporate autonomy, choice, and rights. Our results are meant to encourage members of the global family planning community to think critically about the ethical implications of their existing interventions and how they may be improved. More public health and policy research is required to assess the effect of applying the new indicators with the FP community as well as explicitly outlining monitoring and evaluation strategies for new interventions to allow for programme improvement and the dissemination of lessons learned.
Project description:Cervical cancer (CC) is the most common viral infection of the reproductive tract and in Sub-Saharan Africa (SSA), its morbidity and mortality rates are high. The aim of this review was to map evidence on CC management in SSA. The scoping review was conducted in accordance with Arksey and O'Malley's scoping review framework. The review included studies on different aspects of CC management. The review was also done following the steps and guidelines outlined in the PRISMA-Extension for Scoping Reviews (PRISMA-ScR) checklist. The following databases were searched: PubMed, EBSCOhost, Scopus and Cochrane Database of Systematic Review. A total of 1121 studies were retrieved and 49 which were eligible for data extraction were included in the review. The studies were classifiable in 5 groups: 14 (28.57%) were on barriers to CC screening, 10 (20.41%) on factors associated with late-stage presentation at diagnosis, 11 (22.45%) on status of radiotherapy, 4 (8.20%) on status of chemotherapy and 10 (20.41%) on factors associated with high HPV coverage. High HPV vaccine coverage can be achieved using the class school-based strategy with opt-out consent form process. Barriers to CC screening uptake included lack of knowledge and awareness and unavailability of screening services. The reasons for late-stage presentation at diagnosis were unavailability of screening services, delaying whilst using complementary and alternative medicines and poor referral systems. The challenges in chemotherapy included unavailability and affordability, low survival rates, treatment interruption due to stock-outs as well as late presentation. Major challenges on radiotherapy were unavailability of radiotherapy, treatment interruption due to financial constraints, and machine breakdown and low quality of life. A gap in understanding the status of CC management in SSA has been revealed by the study implying that, without full knowledge of the extent of CC management, the challenges and opportunities, it will be difficult to reduce infection, improve treatment and palliative care. Research projects assessing knowledge, attitude and practice of those in immediate care of girls at vaccination age, situational analysis with health professionals and views of patients themselves is important to guide CC management practice.
Project description:Sub-Saharan Africa represents 69% of the total number of individuals living with HIV infection worldwide and 72% of AIDS deaths globally. Pulmonary infection is a common and frequently fatal complication, though little is known regarding the lower airway microbiome composition of this population. Our objectives were to characterize the lower airway microbiome of Ugandan HIV-infected patients with pneumonia, to determine relationships with demographic, clinical, immunological, and microbiological variables and to compare the composition and predicted metagenome of these communities to a comparable cohort of patients in the US (San Francisco). Bronchoalveolar lavage samples from a cohort of 60 Ugandan HIV-infected patients with acute pneumonia were collected. Amplified 16S ribosomal RNA was profiled and aforementioned relationships examined. Ugandan airway microbiome composition and predicted metagenomic function were compared to US HIV-infected pneumonia patients. Among the most common bacterial pulmonary pathogens, Pseudomonas aeruginosa was most prevalent in the Ugandan cohort. Patients with a richer and more diverse airway microbiome exhibited lower bacterial burden, enrichment of members of the Lachnospiraceae and sulfur-reducing bacteria and reduced expression of TNF-alpha and matrix metalloproteinase-9. Compared to San Franciscan patients, Ugandan airway microbiome were significantly richer, and compositionally distinct with predicted metagenomes that encoded a multitude of distinct pathogenic pathways e.g secretion systems. Ugandan pneumonia-associated airway microbiome is compositionally and functionally distinct from those detected in comparable patients in developed countries, a feature which may contribute to adverse outcomes in this population. Please note that the data from the comparable cohort of patients in the USUS data was published as supplemental material of PMID: 22760045 but not submitted to GEO The 'patient_info.txt' contains 12 clinical, 7 immunological and 3 microbiological variables for each patient.
Project description:BackgroundThe transgender or trans population is one of the most marginalized social groups globally, frequently experiencing ill-treatment and discrimination. This is disproportionately higher in sub-Saharan Africa where trans people experience stigma even in healthcare settings. There is limited evidence concerning the implementation and outcomes of interventions to mitigate this stigma. Therefore, this scoping review aimed to describe interventions and determine their effectiveness in reducing transgender stigma in sub-Saharan Africa.MethodsSearches (completed November 01, 2021, and re-run May 2022) were conducted in MEDLINE (via PubMed), Cochrane Library including the Cochrane Central Register of Controlled Trials, EBSCOhost, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Embase, Web of science, clinicaltrials.gov, and online grey literature sources to identify publications that described interventions to reduce transgender stigma in sub-Saharan Africa.ResultsFrom 877 literature search results, 23 full-text articles were assessed. Data were extracted from the four (4) eligible papers. Only one study explicitly mentioned transgender people. Second, while two studies incorporated conceptual frameworks, they did not show how the frameworks guided the study. The four studies implemented unique interventions at various socio-ecological levels to address individual and interpersonal and structural stigma. Each study utilized a different methodological approach, and the interventions were all evaluated qualitatively.ConclusionsThere is a paucity of transgender stigma reduction interventions implemented in Sub-Saharan Africa with limited evidence of interventions delivered to mitigate stigma at interpersonal and structural levels. Future anti-transgender stigma research should consider reporting details about the core components and descriptions of the interventions. Additionally, the use of validated measures of stigma and the evaluation of interventions for implementation outcomes would be helpful.
