E I Nweze, I E Eke
Dermatophytosis is currently a disease of global importance and a public health burden. It is caused by dermatophytes, which attack and grow on dead animal keratin. Dermatophytes belong to three genera, namely, Epidermophyton, Microsporum, and Trichophyton. The predominant clinical forms and causative agents vary from one region of the world to another. Poor socioeconomic status, high population densities, and poor sanitary conditions are some of the factors responsible for the high prevalence of dermatophytosis in many developing countries, which include countries in southern and eastern Africa, the focus of this review...

This study seeks to determine the prevalence and risk factors for smoking among students aged 12-18 years in two cities in Botswana. Using a sample of 2554 students we adapted the Global Youth Tobacco Survey (GYTS) methodology to assess students' smoking practices, knowledge, beliefs and attitudes. Logistic regression models were used to evaluate factors associated with smoking. The results revealed that 10% of students were current tobacco smokers with 29% reporting having tried smoking. Self-image and acceptance by peers were the strongest predictors of smoking overall (adjusted Odds Ratio [aOR]: 3...

The aim of this article is to investigate the impact of ART perception on risky sexual behaviours in Botswana. Using binary logistic regression analysis controlling for individual characteristics, the results tend to support the hypothesis that ART misconceptions do not necessarily increase risky sexual behaviours. In particular, the study findings suggest the belief that ARVs cure HIV and AIDS and that people on ARVs should not always use condoms do not necessarily lead to increased risky sexual behaviours, particularly among women...

BACKGROUND: Quantifying health care workers' (HCWs') knowledge about tuberculosis (TB) informs educational interventions. We assessed HCWs' knowledge about childhood TB in Botswana. METHODS: Semi-structured interviews were conducted with HCWs at 46 sites around Botswana using a piloted instrument. Transcripts were double-coded using a coding schema. Discrepancies were resolved by consensus and a systematic thematic analysis was performed. RESULTS: The sites (42 clinics and 4 hospitals) were urban (n = 9, 20%), semi-urban (n = 10, 22%) and rural (n = 27, 58%)...

BACKGROUND: Nearly half of child pneumonia deaths occur in sub-Saharan Africa. Microbial communities in the nasopharynx are a reservoir for pneumonia pathogens and remain poorly described in African children. METHODS: Nasopharyngeal swabs were collected from children with pneumonia (N=204), children with upper respiratory infection symptoms (N=55), and healthy children (N=60) in Botswana between April 2012 and April 2014. We sequenced the V3 region of the bacterial 16S ribosomal RNA gene and used partitioning around medoids to cluster samples into microbiota biotypes...

BACKGROUND: Co-trimoxazole prophylaxis reduces mortality among HIV-infected children, but efficacy in HIV-exposed but uninfected (HEU) children in a non-malarial, low-breastfeeding setting with a low risk of mother-to-child transmission of HIV is unclear. METHODS: HEU children in Botswana were randomly assigned to receive co-trimoxazole (100 mg/20 mg once daily until age 6 months and 200 mg/40 mg once daily thereafter) or placebo from age 14-34 days to age 15 months...

PURPOSE: The Collaborative African Genomics Network (CAfGEN) aims to establish sustainable genomics research programs in Botswana and Uganda through long-term training of PhD students from these countries at Baylor College of Medicine. Here, we present an overview of the CAfGEN PhD training program alongside trainees' perspectives on their involvement. BACKGROUND: Historically, collaborations between high-income countries (HICs) and low- and middle-income countries (LMICs), or North-South collaborations, have been criticized for the lack of a mutually beneficial distribution of resources and research findings, often undermining LMICs...

BACKGROUND: Children with cerebral palsy in low-resource settings are at high risk of malnutrition, which further increases their risk of poor health outcomes. However, there are few available data on specific risk factors for malnutrition among children with cerebral palsy in the developing world. METHODS: We performed a case-control study among children with cerebral palsy receiving care at a tertiary care hospital in Gaborone, Botswana. Children with cerebral palsy and malnutrition were identified according to World Health Organization growth curves and compared with subjects with cerebral palsy without malnutrition...

BACKGROUND: HIV point-of-care (POC) testing allows for early infant HIV diagnosis and treatment, but POC accuracy at birth and in the setting of antiretroviral prophylaxis for the prevention of mother-to-child HIV transmission (MTCT) is unknown. METHODS: We evaluated the Cepheid Xpert® HIV-1 Qual POC test against the Roche Taqman HIV-1 PCR platform using dried blood spots from 15 HIV-infected and 75 HIV-exposed uninfected newborns. These infants were screened for HIV at <96 hours of life at 5 hospital maternity wards in Botswana; all infants received post-exposure antiretroviral prophylaxis (PEP) and most mothers received 3-drug antiretroviral therapy in pregnancy and at delivery...

INTRODUCTION: A large and increasing number of HIV-infected women are conceiving on antiretroviral treatment (ART). While most antiretrovirals are considered safe in pregnancy, monitoring for rare pregnancy and infant adverse outcomes is warranted. METHODS: We conducted a retrospective secondary analysis nested within a clinical trial of infant cotrimoxazole vs. placebo prophylaxis in Botswana (the Mpepu Study). Infants were examined at birth, and at least every 3 months through 18 months of age...

BACKGROUND: Health systems across Africa are faced with a multitude of competing priorities amidst pressing resource constraints. Expansion of health insurance coverage offers promise in the quest for sustainable healthcare financing for many of the health systems in the region. However, the broader policy implications of expanding health insurance coverage have not been fully investigated and contextualized to many African health systems. METHODS: We interviewed 37 key informants drawn from public, private and civil society organizations involved in health service delivery in Botswana...

The first records of phlebotomine sandflies from Botswana have been published only recently, comprising of four species of genus Sergentomyia. This update presents the first record of genus Phlebotomus, namely Ph. (Anaphlebotomus) rodhaini Parrot, which is also the first detection of a putative vector of leishmaniasis in Botswana. In addition, records of the Sergentomyia "bedfordi (Newstead) group" are reviewed, and the molecular taxonomy of all taxa known from Botswana is analysed based on three mitochondrial gene fragments (mtDNA)...

Telemedicine can serve as a platform for specialty collaboration and potentially address the lack of specialized and subspecialized care globally. In this article we present a case in which the use of teledermatology facilitated global collaboration between multiple specialists and subspecialists, resulting in high-quality care of a child from a remote area of Botswana. We present the lessons learned and factors that should be considered when engaging in global specialty collaboration, especially between developed and developing countries...

For many parasites, the full set of hosts that are susceptible to infection is not known, and this could lead to a bias in estimates of transmission. We used counts of individual adult parasites from historical parasitology studies in southern Africa to map a bipartite network of the nematode parasites of herbivore hosts that occur in Botswana. Bipartite networks are used in community ecology to represent interactions across trophic levels. We used a Bayesian hierarchical model to predict the full set of host-parasite interactions from existing data on parasitic gastrointestinal nematodes of wild and domestic ungulates given assumptions about the distribution of parasite counts within hosts, while accounting for the relative uncertainty of less sampled species...

BACKGROUND: A majority of health systems in the sub-Saharan Africa region are faced with multiple competing priorities amid pressing resource constraints. Health financing reforms, characterized by expansion of health insurance coverage, have been proposed as promising in the quest to improve health sustainably. However, in many countries where these measures are being attempted, their broader implications have not been fully appreciated. METHODS: This study was based on perspectives of 37 health system stewards from Botswana who were interviewed in order to understand opportunities and challenges that would result in the quest to expand health insurance coverage in the country...

Waste tyres (WTs) are becoming a significant environmental, economical and technological challenge due to their high contents of combustible composition and potential for valuable materials and energy resources. Fewer studies in developing and even developed countries have been carried out to assess the challenges regarding waste tyres management, and suggested the best alternative solutions for managing this waste stream. While developed countries made progress in waste tyres management needs by implementing more efficient innovative recovery and recycling methods, and restrictive regulations regarding the management of used tyres, in many developing countries the management of waste tyres has not received adequate interest, and the processing, treatment and disposal of waste tyre is still nascent...

Food safety information in the African region is insufficient and fragmented due to lack of surveillance, documentation and reporting, thereby resulting in inefficient utilization of resources, duplication of activities, and lack of synergy among the countries of the region. This paper reviews the prevalence of foodborne pathogens in seven African countries (Benin, Botswana, Ghana, Kenya, Nigeria, Sudan and Uganda) from papers in regional or international journals published between January 2000 and December 2015...

BACKGROUND: Botswana is one of the four front line malaria elimination countries in Southern Africa, with malaria control activities that include routine vector control. Past and recent studies have shown that Anopheles arabiensis is the only known vector of Plasmodium parasites in the country. This report presents a preliminary evaluation on Anopheles species composition in seven districts of Botswana with some inferences on their vectorial role. RESULTS: Overall, 404 Anopheles mosquito females were collected, of which 196 were larvae collected from several breeding sites, and 208 were adults obtained from indoor pyrethrum spray catches (PSC)...

The taxonomy of sub-Saharan small insectivore bats of the family Vespertilionidae is unresolved and currently five named species of the genus Neoromicia are recognized from southern Africa, with N. melckorum considered a synonym of N. capensis. Since several years, the name "N. cf. melckorum" has been used in the literature to designate an apparently undescribed and moderately large bodied vespertilionid bat known from different localities in southern and southeastern Africa. Using new data from molecular genetics, bacular morphology, and cranio-dental characters, we conclude that N...
