Background: Despite the adverse health outcomes associated with longer duration diarrhea (LDD), there are currently no clinical decision tools for timely identification and better management of children with increased risk. This study utilizes machine learning (ML) to derive and validate a predictive model for LDD among children presenting with diarrhea to health facilities.
Methods: LDD was defined as a diarrhea episode lasting ≥ 7 days.

To address food and nutrition security in the face of burgeoning global populations and erratic climatic conditions there is a need to include nutrient dense, climatic resilient but neglected indigenous fruit trees in agrifood systems. Here we present the draft genome sequence of Kei Apple, Dovyalis afra, a neglected indigenous African fruit tree with untapped potential to contribute to nutrient security and improved livelihoods. Our long-read-based genome assembly comprises 440 Mbp sequence across 1190 contigs with a N50 and L50 of 13.

Background: Early detection and initiation of care is crucial to the survival and long-term well-being of children living with HIV (CLHIV). However, there remain challenges regarding early testing and linking of CLHIV for early treatment. This study examines the progress made towards achieving the 95-95-95 HIV indicators and associated factors among CLHIV < 15 years in South Africa.

Due to complex interactions, changes in any one area of food systems are likely to impact-and possibly depend on-changes in other areas. Here we present the first annual monitoring update of the indicator framework proposed by the Food Systems Countdown Initiative, with new qualitative analysis elucidating interactions across indicators. Since 2000, we find that 20 of 42 indicators with time series have been trending in a desirable direction, indicating modest positive change.

Research typically promotes two types of outcomes (inventions and discoveries), which induce a virtuous cycle: something suspected or desired (not previously demonstrated) may become known or feasible once a new tool or procedure is invented and, later, the use of this invention may discover new knowledge. Research also promotes the opposite sequence-from new knowledge to new inventions. This bidirectional process is observed in geo-referenced epidemiology-a field that relates to but may also differ from spatial epidemiology.

Introduction: Snakebite envenomation has been declared a neglected tropical disease by the WHO since 2017. The disease is endemic in affected areas due to the lack of availability and access to antivenom, despite it being the standard treatment for snakebites. This challenge is perpetuated by the shortcomings of the regulatory systems and policies governing the management of antivenoms.

Class III malocclusion remains the most challenging occlusal problem to treat due to the complexity of the interrelationships of the underlying skeletal and dental structures. Camouflage orthodontic treatment is a preferred alternative method used to manage mild to moderate Class III malocclusion in nongrowing patients. The aim of this article was to demonstrate a camouflage orthodontic treatment of a 22-year-old female patient diagnosed as having a severe skeletal Class III malocclusion characterized by a straight facial profile, reverse overjet, crowded maxillary incisors, retrognathic maxilla, prognathic mandible, and a hypodivergent facial pattern.

Semiconductor metal oxide gas sensors are widely used to detect ethanol vapours, commonly used in industrial productions, road safety detection, and solvent production; however, they operate at extremely high temperatures. In this work, we present manganese dioxide nanorods (MnO NRs) prepared via hydrothermal synthetic route, carbon soot (CNPs) prepared via pyrolysis of lighthouse candle, and poly-4-vinylpyridine (P4VP) composite for the detection of ethanol vapour at room temperature. MnO, CNPs, P4VP, and MnO NRs-CNPs-P4VP composite were characterised using scanning electron microscopy, transmission electron microscopy, powder X-ray diffraction, Fourier transform infrared spectroscopy, and Raman spectroscopy.

South Africa faces both under- and over-nutrition, highlighting the need for prioritizing nutrition services. Registered dietitians are crucial for delivering appropriate and quality nutrition services. Consequently, this case study employs the World Health Organization evidence-based Workload Indicators of Staffing Need to ascertain the requisite dietetic workforce needed at central and tertiary public hospitals in South Africa.

Cooperation is a pivotal biological phenomenon that occurs in diverse forms. In species that engage in helping, individuals vary in the time they spend together and the degree of their physical proximity, which affects the extent of physical touch between individuals. Here, we propose that touch activates a hormonal feedback loop that supports bond formation and maintenance in mating, parenting, and social contexts.

The reduced cost of next-generation sequencing (NGS) has allowed researchers to generate nuclear and mitochondrial genome data to gain deeper insights into the phylogeography, evolutionary history and biology of non-model species. While the Cape buffalo () has been well-studied across its range with traditional genetic markers over the last 25 years, researchers are building on this knowledge by generating whole genome, population-level data sets to improve understanding of the genetic composition and evolutionary history of the species. Using publicly available NGS data, we assembled 40 Cape buffalo mitochondrial genomes (mitogenomes) from four protected areas in South Africa, expanding the geographical range and almost doubling the number of mitogenomes available for this species.

Introduction: Most drug-resistant tuberculosis (DR-TB) occurs due to transmission of unsuspected or ineffectively treated DR-TB. The duration of treatment to stop person-to-person spread of DR-TB is uncertain. We evaluated the impact of novel regimens, including BPaL, on DR-TB transmission using the human-to-guinea pig (H-GP) transmission model.

Background: Seasonal influenza illness and acute respiratory infections can impose a substantial economic burden in low- and middle-income countries (LMICs). We assessed the cost of influenza illness and acute respiratory infections across household income strata.
Methods: We conducted a secondary analysis of data from a prior systematic review of costs of influenza and other respiratory illnesses in LMICs and contacted authors to obtain data on cost of illness (COI) for laboratory-confirmed influenza-like illness and acute respiratory infection.

Conventionally, the size, shape, and biomechanics of cartilages are determined by their voluminous extracellular matrix. By contrast, we found that multiple murine cartilages consist of lipid-filled cells called lipochondrocytes. Despite resembling adipocytes, lipochondrocytes were molecularly distinct and produced lipids exclusively through de novo lipogenesis.

Species' future distributions are commonly predicted using models that link the likelihood of occurrence of individuals to the environment. Although animals' movements are influenced by physical and non-physical landscapes, for example related to individual experiences such as space familiarity or previous encounters with conspecifics, species distribution models developed from observations of unknown individuals cannot integrate these latter variables, turning them into 'invisible landscapes'. In this theoretical study, we address how overlooking 'invisible landscapes' impacts the estimation of habitat selection and thereby the projection of future distributions.

The Red List Index (RLI) is an indicator of the average extinction risk of groups of species and reflects trends in this through time. It is calculated from the number of species in each category on the IUCN Red List of Threatened Species, with trends influenced by the number moving between categories when reassessed owing to genuine improvement or deterioration in status. The global RLI is aggregated across multiple taxonomic groups and can be disaggregated to show trends for subsets of species (e.

Georgina Mace introduced a compelling perspective on the major shifts in conservation science's framing and purpose from 1960 to 2010. A decade ago, she proposed that the conservation community had begun to move into a new framing of 'people and nature' based on changes in perspectives on the relationships between people and nature and new interdisciplinary concepts and methods used in conservation. Progress in using this frame is clear as 'two-way dynamic relationships between people and nature' have since taken centre stage in science, practice and policy.
