Maternal and newborn health disparities and the health impacts of climate change present grand challenges for global health equity, and there remain knowledge gaps in our understanding of how these challenges intersect. This study examines the pathways through which mothers are affected by seasonal and meteorological factors in sub-Saharan Africa in general, and Kanungu District (Uganda), in particular. We conducted a community-based study consisting of focus group discussions with mothers and interviews with health care workers in Kanungu District...

BACKGROUND: In sub-Saharan Africa, the burden of liver disease associated with chronic hepatitis B (HBV) and HIV is unknown. We characterized liver disease using aspartate aminotransferase-to-platelet ratio index (APRI) and FIB-4 in patients with HIV, HBV, and HIV/HBV co-infection in Tanzania. METHODS: Using a cross sectional design, we compared the prevalence of liver fibrosis in treatment-naive HIV mono-infected, HBV mono-infected, and HIV/HBV co-infected adults enrolled at Management and Development for Health (MDH)-supported HIV treatment clinics in Dar es Salaam, Tanzania...

OBJECTIVE: Long-acting rilpivirine is a candidate for pre-exposure prophylaxis (PrEP) for prevention of HIV-1 infection. However, rilpivirine resistance mutations at reverse transcriptase codon 138 (RT-E138X) occur naturally in a minority of HIV-1-infected persons; in particular those expressing Human Leukocyte Antigen (HLA)-B*18 where RT-E138X arises as an immune escape mutation. We investigate the global prevalence, B*18-linkage and replicative cost of RT-E138X and its regional implications for rilpivirine PrEP...

BACKGROUND: Despite a global reduction in morbidity related to sub-optimal water, sanitation and hygiene, the incidence of such diseases remains a significant problem in sub-Saharan Africa. This study aimed to initially assess the potential effectiveness (primarily in terms of impact on morbidity) of a simple educational intervention delivered in Rwanda. Additionally, we sought to explore feasibility relating to the practicality of evaluating and implementing this type of intervention in a low- and middle-income country...

Hepatocellular carcinoma (HCC) is the sixth most common cancer and the second leading cause of cancer mortality worldwide. Incidence rates of liver cancer vary widely between geographic regions and are highest in Eastern Asia and sub-Saharan Africa. In the United States, the incidence of HCC has increased since the 1980s. HCC detection at an early stage through surveillance and curative therapy has considerably improved the 5-year survival. Therefore, medical societies advocate systematic screening and surveillance of target populations at particularly high risk for developing HCC to facilitate early-stage detection...

Meeting the dual objectives of food security and ecosystem protection is a major challenge in sub-Saharan Africa (SSA). To this end agricultural intensification is considered desirable, yet, there remain uncertainties regarding the impact of climate change on opportunities for agricultural intensification and the adequacy of intensification options given the rapid population growth. We quantify trade-offs between levels of yield gap closure, food availability and forest and woodland conservation under different scenarios...

The incidence of malaria in sub-Saharan Africa is falling and in many countries on the continent the pattern of malaria infection within the country is becoming more heterogeneous. National malaria control programmes need to take this into account and the 'one size fits all' approach to malaria control may no longer be appropriate, with individual approaches being needed in different parts of a country. This applies particularly to decisions on the introduction of new control tools. Recent experience with Seasonal Malaria Chemoprevention and with the RTS,S/AS01 malaria vaccine provides examples of interventions which need to be deployed on a restricted rather than a national basis, taking account of differences in climate and the intensity of malaria infection between regions within a country...

BACKGROUND: Intimate partner physical violence is a common global phenomenon. About 30.00% and 38.83% of women in the world and in sub-Saharan Africa experienced physical violence by their partner respectively in 2013. Though intimate partner violence has serious adverse health consequences, there is limited information about partner violence during pregnancy in Ethiopia. Therefore, the aim of this study was to assess the prevalnce of physical intimate partner violence during pregnancy and associated factors among women attending antenatal care in Shire Endaselassie town, Tigray, northen Ethiopia METHODS: A facility based cross-sectional study was conducted from May 3 to July 6, 2015...

BACKGROUND: Anaemia is common in malaria. It is important to quantitate the risk of anaemia and to distinguish factors related to the natural history of disease from potential drug toxicity. METHODS: Individual-patient data analysis based on nine randomized controlled trials of treatments of uncomplicated falciparum malaria from 13 sub-Saharan African countries. Risk factors for reduced haemoglobin (Hb) concentrations and anaemia on presentation and after treatment were analysed using mixed effect models...

Cassava is the fourth largest source of calories in the world but is subject to economically important yield losses due to viral diseases, including cassava brown streak disease and cassava mosaic disease. Cassava mosaic disease occurs in sub-Saharan Africa and the Asian subcontinent and is associated with nine begomovirus species, whereas cassava brown streak disease has to date been reported only in sub-Saharan Africa and is caused by two distinct ipomovirus species. We present an overview of key milestones and their significance in the understanding and characterization of these two major diseases as well as their associated viruses and whitefly vector...

Hearing loss is the most common sensorineural disorder worldwide and is associated with more than 1000 mutations in more than 90 genes. While mutations in genes such as GJB2 (gap-junction protein β 2) and GJB6 (gap-junction protein β 6) are highly prevalent in Caucasian, Asian, and Middle Eastern populations, they are rare in both native African populations and those of African descent. The objective of this paper is to review the current knowledge regarding the epidemiology and genetics of hearing loss in African populations with a focus on native sub-Saharan African populations...

BACKGROUND: The growing menace of poor quality and falsified drugs constitutes a major hazard, compromising healthcare and patient outcomes. Efforts to assess drug standards worldwide have almost exclusively focused on anti-microbial drugs; with no study to date on cardiovascular drugs. Our study aims to assess quality of seven routinely used cardiovascular medications (anticoagulants, antihypertensives and statins) in ten Sub-Saharan African countries. METHODS: Drugs were prospectively collected using standardized methods between 2012 and 2014 from licensed (random pharmacies) and unlicensed (street-markets) places of sale in Africa...

Despite a poor toxicity profile, zidovudine supersedes abacavir as an alternative first-line agent in most international treatment-guidelines due to concerns about HLA-B*57:01-related abacavir-hypersensitivity. We detected one case of HLA-B*57:01 carriage among 513 HIV-infected individuals in Uganda, which, in combination with prior reports, supports the safety of abacavir in the region.

In this paper, I examine disputes over recent claims that male circumcision reduces HIV risk to suggest a complicated relationship between risk individualization and categorization. Whereas randomized controlled trials (RCTs) conducted in sub-Saharan Africa appear to have provided key evidence for the World Health Organization's endorsement of male circumcision as an HIV prevention strategy, RCTs alone did not provide evidence for the underlying causal mechanism. For that, medical authorities have turned to histo-immunological studies of the foreskin's biomolecular vulnerability to HIV, thus molecularizing risk...

Adolescents in sub-Saharan Africa are at risk for contracting HIV. Although media campaigns have educated the population as a whole, few studies are available about the time sub-Saharan African youth spend listening to and viewing sexual messages via the entertainment and informational media. The goals of this project were: 1) to investigate what programming Nairobi adolescents access; and 2) to investigate the association between frequency of access and level of focus on physical relationships with adolescents' perceptions of descriptive norms of peer sexual behaviour, and their attitudes regarding men as sex driven, women as sex objects, and dating as a sport...

Despite the proven remarkable decline of HIV prevalence in the sub-Saharan Africa region, both sub-regional and within-country disparities in HIV prevalence persist. This paper is a survey of literature on HIV prevalence and spread in Zimbabwe, focusing on provincial differences within the national picture of a decline in new infections. In particular, it raises the question of why prevalence and infection rates seem to be disproportionately higher in Matabeleland relative to other provinces of the country...

While more than a billion people live at risk of neglected tropical diseases in areas of Asia, sub-Saharan Africa, and Latin America, the degree to which such diseases burden countries like the United States is currently unclear. Even though many neglected tropical diseases such as dengue, leishmaniasis, and Chagas disease are not endemic to the United States, the possibility of their emergence is noteworthy, especially in states like Texas, which has high levels of poverty, a large immigrant population, and a climate amenable to the vectors for these diseases and is geographically proximate to endemic areas...
