Improving Learner Performance Through Score Based Analysis on a Gamified AI Driven Cybersecurity Learning Platform

Abstract This study examines whether structured engagement with instructional content improves learner performance on Cyber Security Academy, an AI-driven, gamified cybersecurity learning platform. Activity logs covering 1,500 completed assessments from users in ten Anglophone an...

Artificial Intelligence Benchmarking of Drug-Drug Interaction Alert Suppression Under Unmeasured Renal Function Assay Rounding in District Formularies: A Healthcare Safety-Robustness Evaluation

Drug-drug interaction alert suppression in district formularies depends on renal function estimates that are themselves rounded before they reach the rule engine, and the safety consequences of that rounding are rarely quantified. the present analysis treats alert suppression as...

Artificial Intelligence Causal Inference of Community Clinic Postpartum Haemorrhage Risk Under Unmeasured Misoprostol Tablet Quality Degradation: A Healthcare Instrumental Variable Safety Evaluation

Community clinic protocols for postpartum haemorrhage (PPH) prophylaxis rely on misoprostol tablets whose active-ingredient content is unobserved at the point of care, so that the protective effect of the drug is confounded by an unmeasured quality gradient that varies across bat...

Artificial Intelligence Triage for Snakebite Envenoming Under Variable Antivenom Stock Records: A Constraint-Aware Evaluation of Healthcare Referral Timing in District Hospitals

District hospitals in snakebite-endemic regions frequently decide whether to refer a patient to a tertiary centre before antivenom availability is confirmed, and the resulting referral timing error is a function of both clinical uncertainty and stock-record uncertainty. the prese...

Engineering appetite: commercial framing, ultra-processed products, and the information environment in Nigeria and Uganda

This study examines how commercial framing surrounding ultra-processed products (UPPs) and fast-food chains shape the information environment in Nigeria and Uganda. A qualitative multi-method research design was employed, integrating document review, structured observation of out...

Clinical characteristics and outcomes of acute liver failure in Vietnam

Understanding the etiologies, clinical characteristics, and outcomes of acute liver failure (ALF) is important for guiding management and evaluating prognosis; however, evidence from Vietnam remains limited. We conducted a prospective single-center cross-sectional observational s...

Oral health disparities and social determinants in Cameroon: a scoping review

Abstract Background Oral health disparities represent a major but under-prioritized public health challenge in Cameroon. Despite a growing burden of caries, periodontal disease, and tooth loss, oral health remains marginalized within national policy. Understanding the social dete...

Limitations of routine hepatitis E virus diagnosis in Central African Republic: a comparative evaluation of serological and molecular assays

In the Central African Republic (CAR), data on the disease burden of hepatitis E virus (HEV) infection are limited despite recurrent epidemics. HEV is not routinely tested for in cases of elevated transaminases. Our objective was to evaluate the sensitivity and the specificity of...
