Data on marine litter is crucial to guide waste management but is scarce in third-world countries such as South Africa. We established the first baseline measurement of litter accumulation on two beaches differing in public access in Port Elizabeth, Eastern Cape, the poorest province in South Africa. Four 10-day surveys were conducted on each beach between June 2019 and June 2020. Results revealed that most of the litter (95.7%) was of South African origin and likely came from local land-based sources (e.g., beachgoers or a local river). Daily accumulation rates at the study sites ranged between 24.58 and 86.54 items·100 m·day, an order of magnitude lower than rates from other cities in Africa. However, like elsewhere, plastic (including foam) made up the bulk (74.2%) of litter with food packaging contributing a large portion of this. These findings indicate that local interventions are warranted to reduce litter in Port Elizabeth.

A shortage of trained personnel poses significant challenges to implementing antimicrobial use (AMU) surveillance systems in low- and middle-income countries (LMICs). Traditional training models, such as workshops, seminars and online courses, often lack the sustained engagement and support necessary for deep learning and skill mastery. This article advocates for mentorship as an effective training method for AMU professionals in LMICs.

Lygodactylus geckos represent a well-documented radiation of miniaturized lizards with diverse life-history traits that are widely distributed in Africa, Madagascar, and South America. The group has diversified into numerous species with high levels of morphological similarity. The evolutionary processes underlying such diversification remain enigmatic, because species live in different ecological biomes, ecoregions and microhabitats, while suggesting strikingly high levels of homoplasy.

Background: Worldwide, approximately 2 million children younger than 15 years of age are infected with multidrug-resistant (MDR) , with MDR tuberculosis developing in approximately 30,000 annually. Evidence from randomized, controlled trials on tuberculosis preventive treatment in persons exposed to MDR tuberculosis is lacking.
Methods: In this community-based, multisite, double-blind, cluster-randomized, placebo-controlled trial in South Africa, we assessed the efficacy and safety of levofloxacin as preventive treatment in children with household exposure to an adult with bacteriologically confirmed MDR pulmonary tuberculosis.

The inherent "black box" nature of AI algorithms presents a substantial barrier to the widespread adoption of the technology in clinical settings, leading to a lack of trust among users. This review begins by examining the foundational stages involved in the interpretation of medical images by radiologists and clinicians, encompassing both type 1 (fast thinking - ability of the brain to think and act intuitively) and type 2 (slow analytical - slow analytical, laborious approach to decision-making) decision-making processes. The discussion then delves into current Explainable AI (XAI) approaches, exploring both inherent and post-hoc explainability for medical imaging applications and highlighting the milestones achieved.
