Evidence for a case-based module in the low-resource setting to teach ectopic pregnancy management.

Introduction: Case-based learning (CBL) utilizes authentic clinical cases that connect theory to practice. CBL has been shown to result in deeper learning and high engagement of adult learners. An open-source, web-based CBL module was created to help learners develop the cognitive foundation of ectopic pregnancy management in the low-resource setting.

A GIS-based on application of Monte Carlo and multi-criteria decision-making approach for site suitability analysis of solar-hydrogen production: Case of Cameroon.

This article analyzes and compares three methodologies for identifying suitable regions for solar hydrogen production using photovoltaic panels: AHP (Analytic Hierarchy Process), FAHP (Fuzzy Analytic Hierarchy Process), and MC-FAHP (Monte Carlo FAHP), integrated with GIS (Geographic Information Systems). The study employs ten criteria across technical (Global Horizontal Irradiance, temperature, slope, elevation, orientation), economic (distance from transportation and electrical networks), and social (population density, proximity to residential areas) factors. Environmental and exclusion criteria define restrictive zones.

A family of coexisting multi-scroll chaos and its selected control in coupled non-oscillatory neurons: A case study.

This study presents a family of coexisting multi-scroll chaos in a network of coupled non-oscillatory neurons. The dynamics of the system are analyzed using phase portraits, basins of attraction, time series, bifurcation diagrams, and spectra of Lyapunov exponents. The coexistence of multiple bifurcation diagrams leads to a complex pattern of multi-scroll formation, which is further complicated by the presence of coexisting single-scroll attractors that merge to form multi-scroll chaos.

Factors associated with mortality in thoracic trauma patients in Cameroon.

Background: Thoracic trauma is the third most common cause of death after abdominal injury and head trauma in polytrauma patients. The identification of a patient at risk of thoracic trauma mortality is necessary to avoid delays that may lead to morbidity and mortality. Therefore, the objective was to assess the factors associated with mortality among thoracic trauma patients in Cameroon.

'They went for the test together but came back separately': a constructivist grounded theory perspective on male engagement in antenatal HIV testing in Bamenda, Cameroon.

Introduction: Male engagement in HIV testing during pregnancy significantly contributes towards the prevention of maternal seroconversion and paediatric HIV acquisition. Despite this, men especially the male partners of pregnant women have been consistently missing in the HIV prevention cascade. The factors accounting for sub-optimal levels in male engagement intersect but reasons for this are poorly understood.

Wealth is health: High economic status in Cameroon correlates with protective gear use in traffic injuries and improved clinical outcomes.

Introduction: Africa is the least motorized populated continent, yet it experiences the highest traffic fatality rate. Despite laws mandating helmet and seatbelt use, data on protective gear use among Cameroonian road traffic injury (RTI) patients remains sparse.

Methods: We extracted Cameroon Trauma Registry data prospectively collected from 10 hospitals during July 2022 to December 2023.

Detection and genomic characterisation of foot-and-mouth disease virus serotypes circulating in Cameroon using environmental sampling.

Foot-and-mouth disease virus (FMDV) is a highly contagious, economically important disease of livestock and wildlife species. Active monitoring and understanding the epidemiology of FMDV underpin the foundations of control programmes. In many endemic areas, however, veterinary resources are limited, resulting in a requirement for simple sampling techniques to increase and supplement surveillance efforts.

Regional and institutional trends in assessment for academic promotion.

The assessment of research performance is widely seen as a vital tool in upholding the highest standards of quality, with selection and competition believed to drive progress. Academic institutions need to take critical decisions on hiring and promotion, while facing external pressure by also being subject to research assessment. Here we present an outlook on research assessment for career progression with specific focus on promotion to full professorship, based on 314 policies from 190 academic institutions and 218 policies from 58 government agencies, covering 32 countries in the Global North and 89 countries in the Global South.

Carbon capture from controlled degassing of deep meromictic lakes: Insights to techno-economic and environmental feasibility, from the "killer lakes" in Cameroon.

Carbon dioxide (CO) accumulation and emission are well-known features of deep lakes, making them a significant unavoidable carbon source to the atmosphere. In the case of meromictic lakes, degassing devices are installed to controllably release through a pipe the CO trapped in the bottom waters. Otherwise, the gas is emitted diffusely at the air-water surface or accidentally through a limnic eruption when the saturation limit is reached.

Ecological concrete by partially substitution of cement with Cameroonian corn stover ash.

This study focuses on the influence of the partial substitution of cement by Cameroonian corn stover ash (CCSA) on the physical and mechanical behavior of concrete. For this, as materials used, one has first the corn stovers coming from the Bandjoun town in the Koung-khi division, in the West region of Cameroon, which are used to obtain the ashes, while the sand used, came from the Sanaga River in the coastal region of Cameroon. In order to obtain the CCSA, the corn stover is calcined in an oven at 600 °C for 6 h and then characterized; the characterization included infrared spectrometry, X-ray fluorescence spectrometry, fineness of grinding, and absolute density.

Cophylogeny, narrow host breadth and local conditions drive highly specialized bird-haemosporidian associations in West-Central African sky islands.

The parasite island syndrome denotes shifts in parasite life histories on islands, which affect parasite diversity, prevalence and specificity. However, current evidence of parasite island syndromes mainly stems from oceanic islands, while sky islands (i.e.

Cotton production areas are at high risk of invasion by Amrasca biguttula (Ishida) (Cicadellidae: Hemiptera): potential distribution under climate change.

Background: The cotton jassid, Amrasca biguttula, a dangerous and polyphagous pest, has recently invaded the Middle East, Africa and South America, raising concerns about the future of cotton and other food crops including okra, eggplant and potato. However, its potential distribution remains largely unknown, posing a challenge in developing effective phytosanitary strategies. We used an ensemble model of six machine-learning algorithms including random forest, maxent, support vector machines, classification and regression tree, generalized linear model and boosted regression trees to forecast the potential distribution of A.

Pooling the complex survey data across the 64 lower and middle-income countries: A study on antibiotic usage in under-five children.

Background: Antibiotic exposure for fever/cough has been rising alarmingly, especially among children under five in low- and middle-income countries (LMICs). This excessive use could result in higher healthcare costs, and antibiotic resistance is an alarming trend in developing countries. As a result, it's crucial to look at the variables that affect antibiotic exposure and highlight the subgroups among whom antibiotic abuse is the most prevalent.

Trust in scientists and their role in society across 68 countries.

Science is crucial for evidence-based decision-making. Public trust in scientists can help decision makers act on the basis of the best available evidence, especially during crises. However, in recent years the epistemic authority of science has been challenged, causing concerns about low public trust in scientists.

Perceptions of science, science communication, and climate change attitudes in 68 countries - the TISP dataset.

Science is integral to society because it can inform individual, government, corporate, and civil society decision-making on issues such as public health, new technologies or climate change. Yet, public distrust and populist sentiment challenge the relationship between science and society. To help researchers analyse the science-society nexus across different geographical and cultural contexts, we undertook a cross-sectional population survey resulting in a dataset of 71,922 participants in 68 countries.

Unstable States and the Biologization of Mental Illness.

We critically examine how biological narratives of mental illness mediate relations between personal experiences and socio-structural conditions of distress in crisis contexts. Using three case studies of contemporary crises in Russia, the Republic of Cameroon, and Bangladesh, we showcase the ways in which biological meanings of mental illness carry political and structural significance as authorities employ "biologization" for political ends. In Russia, biologization is strategically useful to authorities seeking to control a populace, as chronic "conditions" can be "treated" indefinitely.
