Environmental enteropathy (EE), the adverse impact of frequent and numerous enteric infections on the gut resulting in a state of persistent immune activation and altered permeability, has been proposed as a key determinant of growth failure in children in low- and middle-income populations. A theory-driven systems model to critically evaluate pathways through which enteropathogens, gut permeability, and intestinal and systemic inflammation affect child growth was conducted within the framework of the Etiology, Risk Factors and Interactions of Enteric Infections and Malnutrition and the Consequences for Child Health and Development (MAL-ED) birth cohort study that included children from eight countries. Non-diarrheal stool samples (N=22,846) from 1253 children from multiple sites were evaluated for a panel of 40 enteropathogens and fecal concentrations of myeloperoxidase, alpha-1-antitrypsin, and neopterin. Among these same children, urinary lactulose:mannitol (L:M) (N=6363) and plasma alpha-1-acid glycoprotein (AGP) (N=2797) were also measured. The temporal sampling design was used to create a directed acyclic graph of proposed mechanistic pathways between enteropathogen detection in non-diarrheal stools, biomarkers of intestinal permeability and inflammation, systemic inflammation and change in length- and weight- for age in children 0-2years of age. Children in these populations had frequent enteric infections and high levels of both intestinal and systemic inflammation. Higher burdens of enteropathogens, especially those categorized as being enteroinvasive or causing mucosal disruption, were associated with elevated biomarker concentrations of gut and systemic inflammation and, via these associations, indirectly associated with both reduced linear and ponderal growth. Evidence for the association with reduced linear growth was stronger for systemic inflammation than for gut inflammation; the opposite was true of reduced ponderal growth. Although Giardia was associated with reduced growth, the association was not mediated by any of the biomarkers evaluated. The large quantity of empirical evidence contributing to this analysis supports the conceptual model of EE. The effects of EE on growth faltering in young children were small, but multiple mechanistic pathways underlying the attribution of growth failure to asymptomatic enteric infections had statistical support in the analysis. The strongest evidence for EE was the association between enteropathogens and linear growth mediated through systemic inflammation. Bill & Melinda Gates Foundation.

Inadequate knowledge and poor attitudes about prostate cancer (PC) negatively affect early screening practices among males. The PC mortality rate is increasing due to late reporting, screening, and treatment. This study explored the awareness, attitudes, and PC screening behaviours among males in the Limpopo, Thulamela municipality. This descriptive cross-sectional study involved 245 males that were randomly selected. A structured questionnaire was used to collect data. Fisher’s exact tests and logistic regression analysis were used to examine the association between sociodemographic variables, awareness, and attitudes towards PC. Our findings revealed that 64.1% demonstrated inadequate awareness about PC. The overall score (84.9%) showed a positive attitude towards PC. However, 87.4% had a negative attitude towards the effectiveness of treatment for PC. The majority (96.7%) of respondents had never undergone a PSA test, although 53.1% were willing to undergo a PSA test. There was a significant positive correlation between awareness of prostate cancer and attitudes toward prostate cancer (r = 0.280, p < 0.001). Health status predicted awareness about PC, while age and health status predicted attitudes towards PC among men. Rural community-based programmes and heightened awareness campaigns are needed to conscientize men about the risk factors, symptoms, diagnosis, and treatment of PC in rural areas of Limpopo.

Child cognitive development is influenced by early-life insults and protective factors. To what extent these factors have a long-term legacy on child development and hence fulfillment of cognitive potential is unknown. The aim of this study was to examine the relation between early-life factors (birth to 2 y) and cognitive development at 5 y. Observational follow-up visits were made of children at 5 y, previously enrolled in the community-based MAL-ED longitudinal cohort. The burden of enteropathogens, prevalence of illness, complementary diet intake, micronutrient status, and household and maternal factors from birth to 2 y were extensively measured and their relation with the Wechsler Preschool Primary Scales of Intelligence at 5 y was examined through use of linear regression. Cognitive T-scores from 813 of 1198 (68%) children were examined and 5 variables had significant associations in multivariable models: mean child plasma transferrin receptor concentration (β: −1.81, 95% CI: −2.75, −0.86), number of years of maternal education (β: 0.27, 95% CI: 0.08, 0.45), maternal cognitive reasoning score (β: 0.09, 95% CI: 0.03, 0.15), household assets score (β: 0.64, 95% CI: 0.24, 1.04), and HOME child cleanliness factor (β: 0.60, 95% CI: 0.05, 1.15). In multivariable models, the mean rate of enteropathogen detections, burden of illness, and complementary food intakes between birth and 2 y were not significantly related to 5-y cognition. A nurturing home context in terms of a healthy/clean environment and household wealth, provision of adequate micronutrients, maternal education, and cognitive reasoning have a strong and persistent influence on child cognitive development. Efforts addressing aspects of poverty around micronutrient status, nurturing caregiving, and enabling home environments are likely to have lasting positive impacts on child cognitive development.

Epilepsy, a common neurological disease, has a significant impact on people living with epilepsy (PLWE), their caregivers, and their family members. Research has consistently shown that the quality of life of PLWE is low. To expand on this knowledge, a non-experimental quantitative survey study was conducted to explore the knowledge, attitudes, and practices (KAP) of caregivers and family members towards epilepsy and epilepsy-related seizures. The study sample consisted of 519 participants from two South African provinces (Limpopo and Mpumalanga), mostly aged 26–35 years. The study revealed that most respondents in Limpopo had no formal education, whereas in Mpumalanga, most had a secondary education. Most respondents (32.4%) reported always using a spoon to prevent tongue biting during seizures. However, 62.4% of respondents reported feeling unprepared to handle an epileptic seizure. Additionally, the majority (54.7%) showed a moderate level of knowledge about epilepsy. Many respondents had a negative attitude towards epilepsy, and there was uncertainty about proper practices during a seizure. In summary, the research highlights unsatisfactory knowledge and practices towards epilepsy and emphasizes the need for increased education and awareness among caregivers and family members. Significant educational investment is needed from medical services to improve epilepsy care, knowledge, and attitudes.

Objective: This study investigates the prevalent issues of healthcare access and the impact of antiseizure treatments among people with epilepsy (PWE) in rural Limpopo and Mpumalanga, South Africa, where healthcare facilities and affordable treatments are often inadequate.Methods: Using a cross‐sectional survey, 162 PWE were selected using multistage sampling across the provinces. Data were collected via a structured questionnaire and analyzed descriptively using SPSS v27.Results: Most of the participants experienced seizures intermittently, with 70.6% in Limpopo and 53.3% in Mpumalanga reporting occasional episodes, whereas a significant minority in both regions—20.6% and 40%, respectively—suffered from frequent seizures. A notable portion of PWE also reported recurring side effects from antiseizure drugs, which led to consequential life disruptions, including educational dropout and unemployment.Significance: The findings underscore an urgent need for enhanced educational programs and increased awareness to improve the understanding and management of epilepsy in these underserved areas. Optimizing care for PWE requires a multifaceted approach, including evaluating healthcare accessibility, affordability, and societal beliefs influencing treatment adherence. The study advocates for government and policy interventions to mitigate the quality of life deterioration caused by epilepsy and its treatment in rural communities.Plain Language Summary: In Limpopo and Mpumalanga, many individuals with epilepsy experience seizures occasionally, while a significant minority have them frequently. Numerous people also suffer recurring side effects from antiseizure medications, impacting their lives severely by causing school dropouts and job losses. This underscores the urgent need for improved education and awareness programs to manage epilepsy in these provinces effectively. The study urges government action and policy reforms to enhance care and support for people with epilepsy in rural areas, aiming to improve their quality of life.
