Diet changes due to urbanization in South Africa are linked to microbiome and metabolome signatures of Westernization and colorectal cancer.

Transition from traditional high-fiber to Western diets in urbanizing communities of Sub-Saharan Africa is associated with increased risk of non-communicable diseases (NCD), exemplified by colorectal cancer (CRC) risk. To investigate how urbanization gives rise to microbial patterns that may be amenable by dietary intervention, we analyzed diet intake, fecal 16 S bacteriome, virome, and metabolome in a cross-sectional study in healthy rural and urban Xhosa people (South Africa). Urban Xhosa individuals had higher intakes of energy (urban: 3,578 ± 455; rural: 2,185 ± 179 kcal/d), fat and animal protein.

'Community health workers are unable to work because they don't have supervisors' - mid-level providers' experiences of a CHW program in rural South Africa.

Introduction: The World Health Organization has called for more than 4 million community health workers (CHWs) globally; yet there are gaps in the evidence of CHWs' impact where studies have not had consistent results. South Africa is currently investing in CHW programs. However, there are significant concerns about the implementation and effectiveness of the program.

The effect of supervision on community health workers' effectiveness with households in rural South Africa: A cluster randomized controlled trial.

Background: Community health workers (CHWs) can supplement professional medical providers, especially in rural settings where resources are particularly scarce. Yet, outcomes of studies evaluating CHWs effectiveness have been highly variable and lack impact when scaled nationally. This study examines if child and maternal outcomes are better when existing government CHWs, who are perinatal home visitors, receive ongoing enhanced supervision and monitoring, compared to standard care.

Values of COVID-19 Self-Testing among Urban and Rural South Africans: A Cross-Sectional Survey.

Self-testing for COVID-19 may be a preferable strategy for identifying SARS-CoV-2 infection among populations in low- and middle-income settings. To determine South Africans' values related to COVID-19 self-testing should it become widely available, a cross-sectional survey was administered in Durban, KwaZulu-Natal Province and the King Sabata Dalindyebo sub-district of the Eastern Cape. A 35-question survey was administered to 531 participants (268 female) in one urban and one rural setting of South Africa.

Community health workers' experiences of supervision in maternal and child health programmes in low- and middle-income countries: A qualitative evidence synthesis.

Maternal and child health programmes often use Community Health Workers (CHWs) to help address poor access to health care, particularly in low- and middle-income countries (LMIC). Supervision has long been recognised as a critical ingredient of successful CHW programmes, yet it is often reported as either of poor quality or absent. There is little research on CHWs' own perception of supervision and to the best of our knowledge, there are no reviews synthesising the evidence of CHWs' experiences of supervision.

WhatsApp-propriate? A retrospective content analysis of WhatsApp use and potential breaches in confidentiality among a team of doctors at a district hospital, South Africa.

Background: There has been a steady increase in the use of electronic media and instant messaging among healthcare professionals, where it has been almost universally adopted in the workplace. The use of WhatsApp and its perceived benefits in healthcare have been extensively studied; however, there are concerns regarding the potential for ethical breaches in confidentiality through shared electronic patient information.

Objectives: To identify the usage characteristics and incidence of shared patient information with WhatsApp use in a team of medical doctors in an unobserved and unregulated setting.

Nevirapine-induced Stevens-Johnson syndrome in children living with HIV in South Africa.

Background: Although adverse drug reactions resulting from the use of nevirapine (NVP) are well described in adults (estimated frequency of 6% - 10%), it has previously been considered less common in children (0.3% - 1.4%).

Associations between Environmental dust composition and Atopic Dermatitis in urban and rural settings.

Background: Environmental exposures are involved in the pathogenesis of the allergic phenotype and in determining which individual triggers a person becomes sensitized to. Atopic dermatitis (AD) may modulate these effects through increased penetration through the skin modifying the immune system and AD may be triggered or intensified by environmental exposures. These exposures and immune-modulating factors may differ in urban and rural environments.

House dust microbiota and atopic dermatitis; effect of urbanization.

Background: Previous studies have shown that a child's risk of developing atopic disease is impacted by both genetic and environmental factors. Because small children spend the majority of their time in their homes, exposure to microbial factors in their home environment may be protective or risk factors for development of atopic diseases, such as atopic dermatitis.

Methods: Dust samples from the homes of 86 Black South African children 12 to 36 months old were collected for analysis of the bacterial microbiome.

Managing pain in HIV/AIDS: a therapeutic relationship is as effective as an exercise and education intervention for rural amaXhosa women in South Africa.

Background: Pain is one of the most prevalent symptoms in people living with HIV/AIDS and is largely undermanaged. Both a peer-led exercise and education Positive Living programme (PL programme) and the PL programme workbook alone were previously found to be effective in reducing pain in urban amaXhosa Women Living With HIV/AIDS (WLWHA). A therapeutic relationship was hypothesised to have contributed to the efficacy of both interventions.

Successful use of an improvised bubble CPAP device for severe respiratory distress caused by pulmonary tuberculosis.

Introduction: This case report discusses the successful use of an improvised bubble continuous positive airway pressure (CPAP) apparatus made using items commonly available in a poorly resourced district hospital.

Case Presentation: A 64-year-old female with no co-morbidities presented with respiratory failure due to pulmonary tuberculosis and was not accepted into the regional Intensive Care Unit (ICU) on referral. She required 8 days of improvised bubble CPAP to maintain adequate oxygen saturation before weaning and eventual discharge.

Community health worker home visiting in deeply rural South Africa: 12-month outcomes.

Home visiting by community health workers (CHW) improves child outcomes in efficacy trials, there is however limited evidence of impact evaluating CHW programmes when operating outside of a research project. A CHW programme, previously demonstrated efficacious in a peri-urban township, was evaluated in a deeply rural context in a non-randomised comparative cohort study. Two non-contiguous, rural areas in the Eastern Cape of South Africa of about equal size and density were identified and 1469 mother-infant pairs were recruited over 33 months.

Molecular IgE sensitization profiles of urban and rural children in South Africa.

Background: Allergens can act as disease-triggering factors in atopic dermatitis (AD) patients. The aim of the study was to elucidate the molecular IgE sensitization profile in children with and without AD living in urban and rural areas of South Africa.

Methods: Specific IgE reactivity was assessed in 166 Black South African children aged 9-38 months using a comprehensive panel of microarrayed allergens.

Community health workers impact on maternal and child health outcomes in rural South Africa - a non-randomized two-group comparison study.

Background: Home visits by paraprofessional community health workers (CHWs) has been shown to improve maternal and child health outcomes in research studies in many countries. Yet, when these are scaled or replicated, efficacy disappears. An effective CHW home visiting program in peri-urban Cape Town found maternal and child health benefits over the 5 years point but this study examines if these benefits occur in deeply rural communities.

What presents to a rural district emergency department: A case mix.

Background: There is little information available on the range of conditions presenting to generalist run rural district hospital emergency departments (EDs) which are the first point of acute care for many South Africans.

Aim: This study aims to assess the range of acute presentations as well as the types of procedures required by patients in a rural district hospital context.

Setting: Zithulele is a 147-bed district hospital in rural Eastern Cape.

Home visits by community health workers in rural South Africa have a limited, but important impact on maternal and child health in the first two years of life.

Background: More than 50% of Africa's population lives in rural areas, which have few professional health workers. South Africa has adopted task shifting health care to Community Health Workers (CHWs) to achieve the Sustainable Development Goals, but little is known about CHWs' efficacy in rural areas.

Methods: In this longitudinal prospective cohort study, almost all mothers giving birth (N = 470) in the Zithulele Hospital catchment area of the OR Tambo District were recruited and repeatedly assessed for 2 years after birth with 84.

Barriers to implementing clinical trials on nonpharmacological treatments in developing countries: lessons learnt from addressing pain in HIV.

Pain affects over half of the people living with HIV/AIDS (LWHA), and pharmacological treatment has limited efficacy. Preliminary evidence supports nonpharmacological interventions. We previously piloted a multimodal intervention in amaXhosa women LWHA and chronic pain in South Africa with improvements seen in all outcomes, in both intervention and control groups.

A Case Study of an Effective and Sustainable Antiretroviral Therapy Program in Rural South Africa.

The delivery of high-quality HIV care in rural settings is a global challenge. Despite the successful expansion of antiretroviral therapy (ART) in Africa, viral load (VL) monitoring and ART adherence are poor, especially in rural communities. This article describes a case study of an ART program in the deeply rural Eastern Cape of South Africa.

Maternal and child health outcomes in rural South African mothers living with and without HIV.

In the era of widespread antiretroviral therapy (ART), consequences of being HIV-exposed is unclear for children, especially in rural communities. A population sample of consecutive births (470/493) in the Eastern Cape of South Africa (SA) were recruited and reassessed at five points over the first 24 months. Maternal and child outcomes between mothers living with and without HIV were assessed using multiple linear and logistic regressions.

Environmental factors associated with allergy in urban and rural children from the South African Food Allergy (SAFFA) cohort.

Background: The prevalence of allergic diseases differs in urban and rural populations.

Objective: We sought to assess associations between environmental and dietary factors with allergic diseases in urban and rural South African children.

Methods: Toddlers aged 12 to 36 months were assessed for food allergen and aeroallergen sensitization, atopic dermatitis, allergic rhinitis, asthma, and challenge-proved food allergy.

Nutrition and allergic diseases in urban and rural communities from the South African Food Allergy cohort.

Unlabelled: This study describes and compares allergic diseases and sensitization in urban and rural children in the SAFFA study cohort as well as infant feeding patterns and nutritional status. We assessed the relationship between nutritional status, breastfeeding, complementary feeding patterns, and atopic diseases including aeroallergen and food allergen sensitization, self-reported atopic dermatitis, allergic rhinitis, asthma, and challenge-proven food allergy (FA).

Methodology: A total of 1185 urban and 398 rural toddlers aged 12-36 months were screened for food sensitization (FS) and FA using skin prick testing and oral food challenges.

Perinatal maternal depression in rural South Africa: Child outcomes over the first two years.

Aims: To examine child outcomes over time among mothers with perinatally depressed mood in rural South Africa (SA).

Methods: A representative sample of consecutive births (470/493) in the OR Tambo District of the Eastern Cape of South Africa (SA) were recruited and were reassessed at five points over the course of the next two years: 85% were reassessed at 3 months, 92% at 6 months, 88% at 9 months, 91% at 12 months, and 88% at 2 years post-birth. Over time, the children of mothers with perinatally depressed mood (16%) were compared to children of mothers without depressed mood using multiple linear and logistic regressions.
