BACKGROUND: The roll out of antiretroviral therapy in Botswana, as in many countries with near universal access to treatment, has transformed HIV into a complex yet manageable chronic condition and has led to the emergence of a population aging with HIV. Although there has been some realization of this development at international level, no clear defined intervention strategy has been established in many highly affected countries. Therefore we explored attitudes of policy-makers and service providers towards HIV among older adults (50 years or older) in Botswana...

BACKGROUND: We sought to determine if HIV-exposed uninfected (HEU) children had worse neurodevelopmental outcomes at 24 months compared with HIV-unexposed uninfected (HUU) children in Botswana. METHODS: HIV-infected and uninfected mothers enrolled in a prospective observational study ("Tshipidi") in Botswana from May 2010 to July 2012. Child neurodevelopment was assessed at 24 months with the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III: cognitive, gross motor, fine motor, expressive language, and receptive language domains) and the Development Milestones Checklist (DMC), a caregiver-completed questionnaire (locomotor, fine motor, language and personal-social domains)...

In despotically driven animal societies, one or a few individuals tend to have a disproportionate influence on group decision-making and actions. However, global communication allows each group member to assess the relative strength of preferences for different options among their group-mates. Here, we investigate collective decisions by free-ranging African wild dog packs in Botswana. African wild dogs exhibit dominant-directed group living and take part in stereotyped social rallies: high energy greeting ceremonies that occur before collective movements...

We examined HIV prevalence among patients 18-49 year olds admitted to a psychiatric hospital in Botswana in 2011 and 2012. The retrospective study analyzed females (F) and males (M) separately, comparing proportions with Chi square test and continuous variables with Wilcoxon rank-sum test, assessing significance at the 5% level. HIV seroprevalence among hospitalized psychiatric patients was much more common among females (53%) compared with males (19%) (p < 0.001). These women also appeared more vulnerable to infection compared with females in the general population (29%) (p < 0...

Percutaneous Central Venous Catheter (CVC) insertion using internal jugular and Subclavian veins routes is common procedure for all intensive care admitted patients and some patients in the ward as demand arises in central and referral hospitals of Botswana. This is a case report of a patient on whom a third attempt of re-inserting a CVC for fluid and total parenteral nutrition (TPN) was made. X-ray showed that left Subclavian inserted catheter was mis-directed to internal jugular vein of the same side creating discomfort to the patient...

Major staple foods in Southern Africa are prone to mycotoxin contamination, posing health risks to consumers and consequent economic losses. Regional climatic zones favor the growth of one or more main mycotoxin producing fungi, Aspergillus, Fusarium and Penicillium. Aflatoxin contamination is mainly reported in maize, peanuts and their products, fumonisin contamination in maize and maize products and patulin in apple juice. Lack of awareness of occurrence and risks of mycotoxins, poor agricultural practices and undiversified diets predispose populations to dietary mycotoxin exposure...

INTRODUCTION: Vaccine acceptance is a critical component of sustainable immunization programs, yet rates of vaccine hesitancy are rising. Increased access to misinformation through media and anti-vaccine advocacy is an important contributor to hesitancy in the United States and other high-income nations with robust immunization programs. Little is known about the content and effect of information sources on attitudes toward vaccination in settings with rapidly changing or unstable immunization programs...

: The Botswana workplace wellness program (WWP) for health care workers (HCWs) was initiated in 2007. WWP implementation was assessed using a sequential, explanatory, mixed methods design including a national implementation assessment (27 health districts) and in-depth interviews (n = 38). Level of implementation varied across districts with health screening, therapeutic recreation, and health promotion implemented more frequently than occupational health activities and psychosocial services. Facilitators to WWP implementation included establishment of a dedicated, diverse WWP committee; provision of administrative support, and integration of activities into organizational culture...

Climate change imposes an urgent need to recognise and conserve the species likely to be worst affected. However, while ecologists have mostly explored indirect effects of rising ambient temperatures on temperate and polar species, physiologists have predicted direct impacts on tropical species. The African wild dog (Lycaon pictus), a tropical species, exhibits few of the traits typically used to predict climate change vulnerability. Nevertheless, we predicted that wild dog populations might be sensitive to weather conditions, because the species shows strongly seasonal reproduction across most of its geographical range...

Heat treatment was one of the first transformative technologies in the southern African Middle Stone Age (MSA), with many studies in the Cape coastal zone of South Africa identifying it as an essential step in the preparation of silcrete prior to its use in stone tool manufacture. To date, however, no studies have investigated whether heat treatment is necessary for all silcrete types, and how geographically widespread heat treatment was in the subcontinent. The aim of this study is to investigate experimentally whether heat treatment continued further north into the Kalahari Desert of Botswana and northernmost South Africa, the closest area with major silcrete outcrops to the Cape...

Health protective sexual communication can reduce HIV transmission, but women in Botswana find it difficult because of cultural barriers, suggesting the need for relevant measures. A Health Protective Sexual Communication Content Discussed Scale was developed and tested among young women aged 21-35 years in Gaborone, Botswana, to guide HIV prevention interventions. The project was conducted from June 2006 to August 2007. Literature review, expert advice, and a qualitative pilot guided the process. The scale had 22 items...
