Monitoring and Human Health Assessment of Trace Elements in Fresh and Dry Fish From Lake Kariba, Siavonga, Zambia

This study investigated the levels of trace elements in two fish species, Kariba bream (Oreochromis mortimeri) and Kapenta (Limnothrissa miodon) from Lake Kariba in two consecutive years, 2021 and 2022. Both Kariba Bream fresh/sun-dried muscle and sun-dried Kapenta tissues were d...

Effectiveness of tuberculosis treatment in individuals exposed to silica or with silicosis: a systematic review and meta-analysis

Tuberculosis (TB) is a global problem affecting large numbers of workers exposed to respirable crystalline silica. Both silicosis and exposure to silica without silicosis increase the risk of active TB. While some studies have suggested that silicotuberculosis (silicosis plus TB)...

Participant attrition in a multi-regional population-based study in Africa: insights from the AWI-Gen study

Attrition in longitudinal studies, defined as the loss of participants over time, may threaten the validity of study results. This study examined patterns, magnitude, and risk factors for attrition in the AWI-Gen cohort. The study included 12,032 participants from six African sit...

Restoring microbial relations and landscapes: a relational conceptual framework for fermentation, culture, and health equity

Introduction: Biodiversity decline in both external environments and internal human microbiomes indicates disrupted relationships between humans, microbes, food systems, and ecological landscapes. These interconnected landscapes are important for global health and sustainability...

Mechanically Dynamic and Immuno-Instructive Biomaterials: Converging Strategies to Direct Cell Fate in Regenerative Microenvironments

Tissue regeneration is influenced by the dynamic interactions between cells and the extracellular matrix (ECM), in which the repair outcomes are collectively determined by the evolving mechanical properties and strictly regulated immune responses. Conventional biomaterials, which...

Patient’s perceived quality of care in South Africa’s public health sector
