Eilat virus isolated from Culex univittatus mosquitoes from the Namibian Zambezi Region influences in vitro superinfection with alpha- and flaviviruses in a virus-species-dependent manner.

The genus Alphavirus harbors arboviruses of great concern, such as the Chikungunya virus and the equine encephalitis viruses. Transmission of pathogenic alphaviruses by mosquitoes could be influenced by insect-specific alphaviruses such as Eilat virus (EILV). However, insect-specific alphaviruses are rarely found in wild mosquitoes and only a few have been described in the literature.

Detection of other pathologies when utilising computer-assisted digital solutions for TB screening.

Background: Computer-aided detection (CAD) tools for TB detection have the potential to enable screening programmes and reduce the diagnostic gap in settings where access to radiologists is limited. However, there are concerns that other common chest X-ray (CXR) abnormalities not due to TB may be missed.

Methods: We assessed the performance of three commercialised CAD tools (qXR, INSIGHT CXR and DrAID TB XR) to detect common non-TB abnormalities against readings with a standardised annotation guide by an expert radiologist.

Hybrid modelling framework for ozonation and biological activated carbon in tertiary wastewater treatment.

Despite water being a significant output of water and resource recovery facilities (WRRFs), tertiary wastewater treatment processes are often underrepresented in integrated WRRF models. This study critically reviews the approaches used in comprehensive models for ozone (O) and biological activated carbon (BAC) operation units for wastewater tertiary treatment systems. The current models are characterised by limitations in the mechanisms that describe O disinfection and disinfection by-product formation, and BAC adsorption in multi-component solutes.

High-Statistics Measurement of the Cosmic-Ray Electron Spectrum with H.E.S.S.

Owing to their rapid cooling rate and hence loss-limited propagation distance, cosmic-ray electrons and positrons (CRe) at very high energies probe local cosmic-ray accelerators and provide constraints on exotic production mechanisms such as annihilation of dark matter particles. We present a high-statistics measurement of the spectrum of CRe candidate events from 0.3 to 40 TeV with the High Energy Stereoscopic System, covering 2 orders of magnitude in energy and reaching a proton rejection power of better than 10^{4}.

Exploring communication gaps and parental needs during paediatric CT scan risk-benefit dialogue in resource-constrained facilities.

Background: Clear communication during informed consent is crucial in paediatric computed tomography (CT) procedures, particularly in resource-constrained settings. CT offers valuable diagnostic information but carries potential radiation risks, especially for paediatric patients. Parents play a critical role in decision-making, necessitating thorough risk-benefit discussions.

A comparative analysis of physical fitness characteristics and rugby-specific game skills of schoolboy players by playing standards: Implications for talent identification programs in resource-constrained settings.

Background: Rugby has not grown extensively in Africa compared to other continents, necessitating talent identification (TID) programs to recruit junior talent. However, it is unclear which physical characteristics and rugby-specific game skills to base the objective recruitment of potentially talented young players.

Objectives: This study profiled the physical fitness characteristics and rugby-specific game skills of schoolboy rugby players by playing standards to identify variables differentiating elite from sub-elite players from Under 16 (U16) to U19 age categories.

Knowledge, attitudes, and practices on hypertension among the health science faculty and students at the University of Namibia: A cross-sectional study.

Hypertension is a serious health concern, especially in developing countries, and assessing people's knowledge, attitudes, and practices (KAP) is important for its awareness and management. This cross-sectional study aimed to assess the KAP on hypertension among students and staff from the Health Sciences and Veterinary Medicine Faculty of the University of Namibia. A cross-sectional study design was conducted on adult participants who completed the KAP questionnaire while resting, and thereafter their blood pressure (BP) was measured.

Predictors for vaccine hesitancy among nursing students in Namibia.

Background: Healthcare workers (HCWs) are a priority group targeted for vaccination because they are greatly exposed to infectious agents.

Aim: To determine the prevalence of coronavirus disease 2019 (COVID-19) vaccination and associated risk factors for vaccine hesitancy to recommend vaccine uptake strategies among student nurses.

Setting: The study was carried out at the University of Namibia, main campus in Windhoek.

Introduction: Globally, health care organizations need to provide quality, culturally congruent health care to increasingly diverse patients. Nursing education institutions must therefore produce culturally competent nursing professionals to provide safe and culturally congruent care. This review aimed to identify and outline strategies to enhance cultural competence of undergraduate nursing students.

Cost-effectiveness analysis of a prediction model for community-based screening of active tuberculosis.

Background: Active case finding could effectively detect tuberculosis (TB) patients, but it can be costly. Therefore, a feasible, cost-saving, and efficient algorithm for community-based TB screening is needed.

Methods: The study population was based on a previous TB prevalence survey conducted in the Zambia/South Africa Tuberculosis and HIV/AIDS Reduction trial.

Schools of public health as a cornerstone for pandemic preparedness and response: the Africa COVID-19 experience.

Background: The Coronavirus disease (COVID-19) pandemic caused significant morbidity and mortality in Africa, in addition to other socio-economic consequences. Across the continent, Schools of Public Health (SPHs) played several roles in supporting national, regional, and global response to the pandemic. Following a published and grey literature search, this paper reviews and analyses the contribution of SPHs in Africa during the COVID-19 pandemic.

PhysioCAFUN: A competency-based curriculum development guideline to strengthen physiology education in Africa.

Physiology education in Africa faces challenges due to gaps in curricula across many of its universities, such as divergent content, a lack of standardized competencies, and suitable benchmarking. Here, we describe the development of Physiology Curriculum for African Universities (PhysioCAFUN), a competency-based curriculum development guideline, as a first step to address such shortcomings. A committee of 15 physiologists from different African regions, Europe, and USA was constituted to draft the PhysioCAFUN, which was introduced and revised during the joint East African Society of Physiological Sciences (EASPS) and African Association of Physiological Sciences (AAPS) conference held in Tanzania late 2023.

Knowledge and Adherence to Radiation Protection among Non-Radiation Health Care Workers at Two Operating Theatres in Windhoek, Namibia.

Background: In operating theatres, diagnostic radiography is used to capture images during surgical operations. With the growing use of fluoroscopy, there are concerns about increased radiation exposure to healthcare workers such as doctors and nurses. Thus, assessing HCWs' knowledge and adherence to radiation protection is crucial to prevent overexposure, radiation-related health issues, and ensure patient safety.

The cross-cultural big two: A culturally decentered theoretical and measurement model for personality traits.

A "big two" model has shown stronger cross-cultural replicability and links to theory than other contemporary models of personality trait structure. However, its theoretical and measurement models require better specification. We address this to create an initial English-language version of the Cross-Cultural Big Two Inventory with an empirically informed and culturally decentered approach, meaning that input from global contexts is used from the outset, without prioritizing Western perspectives.

as a risk driver and change agent for the Cuvelai-Etosha basin rural communities.
