UNASSIGNED: Disturbed sleep during infancy and early childhood can have a detrimental effect on parental sleep and consequently parental well-being. However, there is a paucity of research on how perceived child sleep problems and behavioural sleep interventions as treatment influence maternal subjective well-being.
UNASSIGNED: This study aimed to explore the incidence of subjective well-being in mothers of children with sleep problems and whether implementing two behavioural sleep interventions changed their well-being.
UNASSIGNED: The research was conducted in a community setting, with parents voluntarily approaching a sleep consultancy based in South Africa.
UNASSIGNED: Using data from 119 mothers voluntarily approaching a sleep consultancy in South Africa, a pre-test-post-test design was employed to investigate changes in life satisfaction, affect, couple satisfaction, perceived stress and depression approximately 3 weeks after implementation of a sleep intervention.
UNASSIGNED: Results indicate that mothers of children with sleep problems experienced moderate to high life satisfaction and positive affect although the presence of moderate negative affect, couple satisfaction and stress and mild depression suggest possible decreased subjective well-being.
UNASSIGNED: Findings suggest implementation of graduated extinction and extinction with parental presence sleep interventions may improve life satisfaction, affect, stress and depression but not couple satisfaction in the short-term.
UNASSIGNED: This study contributes towards understanding the effect of sleep loss on the subjective well-being of mothers and provides preliminary evidence regarding the benefits of two sleep interventions for improving maternal subjective well-being.

Avian species diversity in Southern Africa is remarkably high, yet the mechanisms responsible for that diversity are poorly understood. While this is particularly true with respect to species endemic to the subregion, it is unclear as to how more broadly distributed African species may have colonized southern Africa. One process that may in part account for the high bird species diversity in southern Africa is a \"species pump\" model, wherein the region was repeatedly colonized by lineages from areas further north: a pattern related to climate cycling and the eastern African arid corridor. Once occupying southern Africa, with its many varied biomes, it is possible that climate cycling further affected lineages by generating genetic diversity in multiple refugia, a pattern recently shown for several southern African bird species. Here, we used mtDNA to address these questions in a widespread, sedentary habitat generalist bird species, the familiar chat (Oenanthe familiaris). The phylogenetic structure suggests a north-to-south colonization pattern, supporting the \"species pump\" model. Haplotype diversity was partitioned into two distinct clusters: southern Africa and Malawi (East Africa). Southern African haplotypes were not geographically partitioned, and we hypothesize that this pattern has arisen because this species is a habitat generalist, and as such resilient to habitat-altering climate perturbations. Based on our phylogenetic results, we discuss the validity of currently recognized subspecies.

Data collection was implemented through an initiative by the Child Health and Mortality Prevention Surveillance (CHAMPS) Network to assess whether lockdowns and other social distancing policies during COVID-19 had implications for household economic status, maternal and child health, and healthcare accessibility for pregnant women and children. The data were collected from April 2021 until February 2022 from a population living in a rural community of Mozambique. This rural community is located within a Health and Demographic Surveillance System (HDSS) that operates in the Manhiça district of Maputo province. The survey instrument used for data collection was specifically designed to examine household awareness, knowledge, and prevalence of COVID-19; it was also designed to document hardships experienced by households during the pandemic period such as food insecurity, job losses and/or business closures of household members, and access to healthcare. The data are generalizable to a contiguous community in Manhiça, Mozambique of approximately 200,000 inhabitants.

Gut bacterial communities provide flexibility to hosts during dietary changes. Despite the increasing number of studies exploring the associations between broader dietary guilds of mammalian hosts and their gut bacteria, it is generally unclear how diversity and variability in consumed diets link to gut bacterial taxa in wild non-primate mammals, particularly in omnivores. Here, we contribute to filling this gap by exploring consumed diets and gut bacterial community compositions with metabarcoding of faecal samples for two African mammals, Civettictis civetta and Genetta spp., from the family Viverridae. For each individual sample, we characterised bacterial communities and identified dietary taxa by sequencing vertebrate, invertebrate and plant markers. This led us to establish diet compositions that diverged from what has previously been found from visual identification methods. Specifically, while the two genera have been categorised into the same dietary guild, we detected more animal dietary items than plant items in C. civetta, while in Genetta spp., we observed the opposite. We further found that individuals with similar diets have similar gut bacterial communities within both genera. This association tended to be driven by specific links between dietary items and gut bacterial genera, rather than communities as a whole, implying diet-driven selection for specific gut microbes in individual wild hosts. Our findings underline the importance of molecular tools for improving characterisations of omnivorous mammalian diets and highlight the opportunities for simultaneously disentangling links between diets and gut symbionts. Such insights can inform robustness and flexibility in host-microbe symbioses to dietary change associated with seasonal and habitat changes.

BACKGROUND: Angola has an extraordinary plant diversity and a great ethnobotanical potential. However, there is a general lack of information about the first botanical explorations in the country and their contribution to the knowledge of the medicinal flora.
OBJECTIVE: The main aim of this study was to unveil the ethnobotanical legacy of José Maria Antunes and Eugène Dekindt, priests of the first Catholic mission in Huíla (Angola) and shed light on their contribution to the knowledge of medicinal wild plants of the country, including information on the uses, plant parts used, and preparation methods documented in the late 19th century. The findings are discussed considering recent ethnobotanical studies to offer a more comprehensive understanding of the historical and traditional uses of plants in Angola over the last two centuries.
METHODS: Based on the information available in manuscripts and on the study of botanical collections preserved in herbaria of Portugal and Angola, we extracted relevant information about the species used in traditional medicine by the rural population of Huíla, the health conditions treated, and the mode of preparation and application.
RESULTS: Our results revealed that Antunes and Dekindt conducted the first ethnobotanical study in Huíla, and documented a large number of medicinal wild plants. From these, we report 191 medicinal species, including 25 endemic and four introduced species, belonging to 56 plant families and 146 genera. Fabaceae family presents the highest richness of medicinal plants (39 taxa), followed by Rubiaceae (13), Asteraceae (10), and Apocynaceae (9). The illnesses reported were classified into 15 different categories, with the highest number of species (49) corresponding to unspecific conditions, such as general pains, chills, and fever. Thirty-seven species were reported for respiratory diseases, 31 for musculoskeletal problems, and 30 for digestive issues. Leaves were the most used plant part for medicinal purposes (84 species). Infusion was the most frequently described preparation method (40 species), followed by maceration (24 species), and powdering (36 species).
CONCLUSIONS: The legacy of Antunes and Dekindt\'s work improves our understanding of Angola\'s botanical richness and traditional uses of plant resources. Our findings highlight the presence of unique medicinal resources in Angola, especially among endemic species, which hold the potential to improve the quality of life of rural communities. Moreover, our research underscores the lack of knowledge of medicinal species, emphasizing the risk of losing valuable historical information.

While ear, nose, and throat (ENT) diseases are a substantial threat to global health, comprehensive reviews of ENT services in Southern Africa remain scarce.
This scoping review provides a decade-long overview of ENT services in Southern Africa and identifies gaps in healthcare provision. From the current literature, we hope to provide evidence-based recommendations to mitigate the challenges faced by the resource-limited ENT service.
PubMed, Web of Science, EBSCOhost, Cochrane Library, Cochrane Library, and Scopus.
On several databases, we conducted a comprehensive literature search on both quantitative and qualitative studies on ENT services in Southern Africa, published between 1 January 2014 and 27 February 2024. The extracted data from the analyzed studies was summarized into themes.
Four themes in the fourteen studies included in the final analysis described the existing ENT services in Southern Africa: 1. Workforce scarcity and knowledge inadequacies, 2. Deficiencies in ENT infrastructure, equipment, and medication, 3. Inadequate ENT disease screening, management, and rehabilitation and 4. A lack of telehealth technology.
The Southern African ENT health service faces many disease screening, treatment, and rehabilitation challenges, including critical shortages of workforce, equipment, and medication. These challenges, impeding patient access to ENT healthcare, could be effectively addressed by implementing deliberate policies to train a larger workforce, increase ENT funding for equipment and medication, promote telehealth, and reduce the patient cost of care.
Main findings: Ear, nose and throat (ENT) healthcare in Southern Africa faces critical shortages of workforce, equipment, and medication for disease screening, treatment and rehabilitation.Added knowledge: In this review, we identify challenges in the resource-limited Southern African ENT healthcare provision and provide evidence-based recommendations to mitigate these challenges.Global health impact for policy and action: Improving ENT service delivery in the resource-limited world requires deliberate policies that improve health worker training, expand financing and resource availability, incorporate new technology, and lower patient costs of care.

This paper provides an overview of the HEAT (Healthy Environments for AthleTes) project, which aims to understand the impact of environmental conditions on athlete health and performance during major sporting events such as long-distance running, cycling, and triathlons. In collaboration with the SAFER (Strategies to reduce Adverse medical events For the ExerciseR) initiative, the HEAT project carried out a field campaign at the 2022 Comrades Marathon in the KwaZulu-Natal province of South Africa. The measurement campaign deployed seven weather stations, seven PM2.5 monitors and one spore trap along the 90 km route to capture spatially representative measurements of complex micro-climates, allergenic aerospora, and particulate matter exposure. The results indicate that runners were exposed to moderate risk heat stress conditions. Novel findings from this initial campaign shows elevated and potentially harmful PM2.5 levels at spectator areas, possibly coinciding with small fire events around the race day festivities. Our findings show values PM2.5 levels over the WHO 24-h guidelines at all stations, while 2000 µg/m3 at two stations. However, the lack of an acute exposure standard means direct health impacts cannot be quantified in the context of a sport event. The HEAT project highlights important aspects of race day monitoring; regional scale climatology has an impact on the race day conditions, the microclimatic conditions (pollution and meteorology) are not necessarily captured by proximity instruments and direct environmental measurements are required to accurately capture conditions along the route.

BACKGROUND: People with human immunodeficiency virus (PWH) on first-line, nonnucleoside reverse-transcriptase inhibitor-based antiretroviral therapy (ART) were routinely switched to tenofovir-lamivudine-dolutegravir. We examined virologic outcomes and drug resistance in ART programs in Malawi, where switching was irrespective of viral load, and Zambia, where switching depended on a viral load <1000 copies/mL in the past year.
METHODS: We compared the risk of viremia (≥400 copies/mL) at 1 and 2 years by viral load at switch and between countries using exact methods and logistic regression adjusted for age and sex. We performed HIV-1 pol Sanger sequencing on plasma samples with viral load ≥1000 copies/mL.
RESULTS: A total of 2832 PWH were eligible (Malawi 1422, Zambia 1410); the median age was 37 years, and 2578 (91.0%) were women. At switch, 77 (5.4%) were viremic in Malawi and 42 (3.0%) in Zambia (P = .001). Viremia at switch was associated with viremia at 1 year (adjusted odds ratio (OR), 6.15; 95% confidence interval [CI], 3.13-11.4) and 2 years (7.0; 95% CI, 3.73-12.6). Viremia was less likely in Zambia than in Malawi at 1 year (OR, 0.55; 0.32-0.94) and 2 years (OR, 0.33; 0.18-0.57). Integrase sequencing was successful for 79 of 113 eligible samples. Drug resistance mutations were found in 5 PWH (Malawi 4, Zambia 1); 2 had major mutations (G118R, E138K, T66A and G118R, E138K) leading to high-level dolutegravir resistance.
CONCLUSIONS: Restricting switching to dolutegravir-based ART to PWH with a viral load <1000 copies/mL may reduce subsequent viremia and, consequently, the emergence of dolutegravir drug resistance mutations.

Two articles by Garenne (2023a,b) argue that voluntary medical male circumcision does not reduce human immunodeficiency virus transmission in Africa. Here we point out key evidence and analytical flaws that call into question this conclusion.

BACKGROUND: For the first time in two decades, a comprehensive, up-to-date overview of the medicinal and ritual plants of southern Africa is presented. This data is analysed and compared with a previous survey done in 2002.
OBJECTIVE: The main aim is to update the checklist of medicinal and ritual plants of southern Africa and to determine the number of new records since 2002. We also provide a high-level perspective on the selection of medicinal and ritual plant species in southern Africa, a taxonomic analysis of the new checklist as well as a chronological perspective on the citation of medicinal and ritual species before and after 2002.
METHODS: The most recently published medicinal and ritual plants checklist for southern Africa was reviewed and updated. A wide range of ethnobotanical literature, including books, field guides and electronic journals, was used. All calculations were done by using formulas and functions in Microsoft Excel and R Studio.
RESULTS: 4120 medicinal and ritual taxa and 3784 medicinal and ritual species have been recorded. Compared with the 2002 checklist, there are 1239 new taxa (1228 new species). A strong correlation between available taxa and selected medicinal taxa exists on order level, which corresponds with the results of an analysis done in 2008. The top 10 species-rich medicinal plant families of southern Africa are Asteraceae, Fabaceae, Apocynaceae, Euphorbiaceae, Asphodelaceae, Malvaceae, Lamiaceae, Poaceae, Rutaceae and Rubiaceae. Different patterns of plant family representation can be seen across certain cultural healing systems of southern Africa. The species popularity (number of citations) of Hypoxis hemerocallidea Fisch. & C.A.Mey. Has increased substantially after 2002. Other medicinal and ritual plant species have been consistently researched, such as Artemisia afra Jacq. ex Willd., Carpobrotus edulis (L.) L.Bolus, Aloe ferox Mill., Leonotis leonurus (L.) R.Br. and Gunnera perpensa L.
CONCLUSIONS: The numerous new medicinal and ritual plant records that have been reported in the last two decades provide evidence of an incompletely documented ethnobotanical heritage that urgently requires documentation. Patterns of taxonomic diversity on family level indicate distinctive differences between cultural healing systems. Signs of the adaptability and dynamics of traditional healing systems in southern Africa can be seen in the changes in the citation of species over time.
