Hydrogeochemical processes regulating groundwater quality and its suitability for drinking purposes in the recent alluvial plain, Blue Nile Region, Sudan.

Groundwater is becoming a critical freshwater source in the Blue Nile Region, Sudan. However, overexploitation and contamination increasingly threaten its sustainability. This study evaluates the hydrogeochemical processes influencing groundwater and its suitability for drinking purposes in the recent alluvial plain.

Unusual Presentation of Confusion: Hyperammonaemic Hepatic Encephalopathy Due to Intrahepatic Portosystemic Venous Shunt.

Presentation: A 75-year-old man presented to the emergency department with a 5-week history of confusion, daytime somnolence, and fatigue. His physical examination was unremarkable.

Diagnosis: Investigations initially showed deranged Liver function tests.

Wastewater surveillance overcomes socio-economic limitations of laboratory-based surveillance when monitoring disease transmission: The South African experience during the COVID-19 pandemic.

Wastewater and environmental surveillance has been promoted as a communicable disease surveillance tool because it overcomes inherent biases in laboratory-based communicable disease surveillance. Yet, little empirical evidence exists to support this notion, and it remains largely an intuitive, though highly plausible hypothesis. Our interdisciplinary study uses WES data to show evidence for underreporting of SARS-CoV-2 in the context of measurable and statistically significant associations between economic conditions and SARS-CoV-2 incidence and testing rates.

Repurposing the composite assessment of index lesion severity scoring system in cutaneous lichen planus.

Current validated lichen planus (LP) scoring systems are complicated and optimized for generalized, multi-site disease. There is a need for a validated, simple lesional assessment in LP. Herein, we repurpose and optimize the modified Composite Assessment of Index Lesion Severity (mCAILS) for LP and to validate the optimized lichen planus CAILS (lpCAILS).

Assessing the quality of life among African medical and health science students using the WHOQOL-BREF tool.

Background: The quality of life (QoL) among health professional students is available in the literature, yet there is a paucity of information concerning QoL among African students. The study aimed to measure the QoL with the World Health Organization Quality of Life-BREF (WHOQOL-BREF) tool among African medical and health science students.

Methods: A cross-sectional study was conducted involving 349 African medical and health science students from various disciplines at the International African University in May 2024.
