Seasonal variation in soil macrofauna and soil physical and chemical properties in homegarden agroforestry systems of North Wollo, Ethiopia

Homegarden agroforestry systems support soil biodiversity and nutrient cycling, yet seasonal variation in soil macrofauna remains insufficiently documented in northern Ethiopia. This study evaluated seasonal variation in soil macrofauna abundance, biomass, diversity, and selected...

Perceived social support, self-esteem, and academic performance among students with visual impairment in Ethiopian middle schools

Students with visual impairments frequently encounter academic challenges influenced not only by instructional accessibility but also by psychosocial factors. Although inclusive education policies have expanded access for students with disabilities, critical gaps persist in under...

Association between climate variability adaptation practices and household food security in three agro-ecological zones of northwestern Ethiopia

Climate variability increasingly threatens smallholder agriculture and food security in sub-Saharan Africa, yet evidence on the comparative effectiveness of adaptation strategies, particularly integrated portfolios, remains limited. This study examines the association between cli...

Magnitude and determinants of major adverse events and treatment outcomes after surgical repair of ventricular septal defects in children: a 15-year experience

Abstract Ventricular septal defect (VSD) is the most common congenital cardiac anomaly requiring surgical intervention. Although surgical outcomes have improved worldwide, complication rates continue to vary across regions. In Ethiopia, evidence on postoperative outcomes followin...

Fungal-derived chitosan for active food packaging: Comparison to animal-derived chitosan, challenges, and future prospects of Ganoderma lucidum-derived chitosan

Chitosan is one of the most extensively studied biopolymers for active food packaging because of its excellent film-forming, antimicrobial, antioxidant, and biodegradable properties. However, the broader application of conventional animal-derived chitosan, primarily obtained from...

Spatio-temporal dynamics of phytoplankton community in relation to environmental variables in Lake Maybar, Ethiopia

This study investigated the spatiotemporal dynamics of phytoplankton communities and physicochemical water quality parameters in Lake Maybar across seasonal variations. Sampling was conducted from 2023 to 2025 at three sites to evaluate phytoplankton composition, abundance, and b...

Evaluating the timeliness of care: delayed presentation and its predictors among patients with ischemic stroke at a tertiary care hospital in Northern Ethiopia

Stroke is a leading cause of morbidity and mortality worldwide, with ischemic stroke being the most common subtype. Timely presentation is critical for optimal management and improved outcomes. A prospective observational study was conducted at the University of Gondar Comprehens...

The global prevalence of hemorrhoids: a systematic review and meta-analysis

Abstract Objective Hemorrhoidal disease is a common anorectal condition, yet its global prevalence remains unclear. Thus, this systematic review and meta-analysis aimed to estimate worldwide prevalence and explore variation by region, sex, diagnostic approach, and study setting....

Development and validation of a lung cancer risk prediction model in Ethiopia

An advanced stage of presentation is common among lung cancer patients in low-resource settings, leading to late diagnosis and poor prognosis. Early identification of high-risk individuals is essential to enable targeted prevention and timely diagnosis. We conducted a case–contro...

Retrieval of Optically Active and Inactive Water Quality Parameters Using Remote Sensing and Machine Learning: Evidence from Water Hyacinth-Infested Lake Tana, Ethiopia

Monitoring water quality is critical for protecting freshwater ecosystems and supporting sustainable water resource management. Lake Tana, Ethiopia’s largest freshwater lake, faces increasing agricultural and urban pressures, while conventional monitoring remains costly and spati...

Organizational culture and sustainability practices as drivers of shared value creation: evidence from Ethiopian private-sector firms

Purpose This paper aims to explore the role played by organizational culture in the establishment of shared value creation in emerging-economy firms through sustainability practices. Design/methodology/approach The study relies on the resource-based view, the Denison organization...

Nasopharyngeal Carriage Rate, Risk Factors, and Co‐Resistance Patterns of Methicillin‐Resistant Staphylococcus aureus in Ethiopia: Systematic Review and Meta‐Analysis

ABSTRACT Methicillin‐resistant Staphylococcus aureus (MRSA) nasopharyngeal carriage is a major global health concern linked to severe infections and transmission. However, comprehensive evidence on the burden of MRSA carriage, antimicrobial resistance, and associated risk factors...

Recombinant antigens derived from Rickettsia prowazekii GltA: from in silico design to preliminary serological evaluation

Epidemic typhus, caused by Rickettsia prowazekii , remains a re-emerging public health concern in resource-limited and conflict-affected regions, underscoring the need for improved diagnostic tools. Although the citrate synthase (GltA) gene is widely used as a molecular diagnosti...
