Community-based newborn care intervention fidelity and its implementation drivers in South Wollo Zone, North-east Ethiopia.

Community-based newborn care (CBNC) has been implemented in Ethiopia across the maternal, neonatal, and child health continuum of care with the goal of lowering newborn mortality. However, neonatal mortality rate in Ethiopian is among the highest in the world. Why neonatal mortality remains high in the face of such effective interventions is the issue.

Food consumption patterns in employees of Ethiopian institute of agricultural research.

In developing countries, including Ethiopia, diet-related non-communicable diseases are prevalent among the working population. Understanding this active group's dietary diversity and food consumption patterns is essential to devise alternative solutions and recommend possible improvements. This study investigates the food consumption patterns of employees of the Ethiopian Institute of Agricultural Research.

Catheter-associated urinary tract infection by progresses through acute and chronic phases of infection.

Healthcare-associated infections are major causes of complications that lead to extended hospital stays and significant medical costs. The use of medical devices, including catheters, increases the risk of bacterial colonization and infection through the presence of a foreign surface. Two outcomes are observed for catheterized patients: catheter-associated asymptomatic bacteriuria and catheter-associated urinary tract infection (CAUTI).

Patatin-like phospholipase CapV in Escherichia coli - morphological and physiological effects of one amino acid substitution.

In rod-shaped bacteria, morphological plasticity occurs in response to stress, which blocks cell division to promote filamentation. We demonstrate here that overexpression of the patatin-like phospholipase variant CapV, but not CapV, causes pronounced sulA-independent pyridoxine-inhibited cell filamentation in the Escherichia coli K-12-derivative MG1655 associated with restriction of flagella production and swimming motility. Conserved amino acids in canonical patatin-like phospholipase A motifs, but not the nucleophilic serine, are required to mediate CapV phenotypes.

A mixed methods analysis of the magnitude and associated factors of time management practice among primary hospital employees in North Gondar, Ethiopia.

Time management contributes to work efficiency, maintaining balance, and job satisfaction by promoting productivity and success. Most people believe they have so much to do and not enough time, and they attribute their unmet expectations, poor results, and low productivity to a lack of time. The aim of this study was to determine the magnitude and associated factors of time management practice among primary hospital employees in North Gondar, Ethiopia.

Intervention fidelity and its determinants of focused antenatal care package implementation, in south Wollo zone, Northeast Ethiopia.

Background: Focused antenatal care is directed at sustaining maternal health and improving fetal wellbeing to ensure birth of a healthy neonate. Failure to implement focused antenatal care can result in inability to reduce maternal and perinatal morbidity and mortality in low income countries. Due to evidence-practice gaps, however, thousands of maternal, fetal and neonatal lives are still lost every day, mostly from preventable causes.

Cost of Hemodialysis Treatment and Associated Factors Among End-Stage Renal Disease Patients at the Tertiary Hospitals of Addis Ababa City and Amhara Region, Ethiopia.

Purpose: Hemodialysis is a renal replacement therapy for end-stage renal disease (ESRD) patients who consume substantial healthcare resources, which increases the economic burden. Plenty of factors affects the cost of hemodialysis treatment, particularly in resource-limited settings. Moreover, the demand for hemodialysis may decrease as the cost increases, but there is limited evidence in Ethiopia.

Interaction of and Host Cells upon Infection of Bronchial Epithelium during Different Stages of Regeneration.

The primary barrier that protects our lungs against infection by pathogens is a tightly sealed layer of epithelial cells. When the integrity of this barrier is disrupted as a consequence of chronic pulmonary diseases or viral insults, bacterial pathogens will gain access to underlying tissues. A major pathogen that can take advantage of such conditions is , thereby causing severe pneumonia.

Molecular mechanisms of probiotic prevention of antibiotic-associated diarrhea.

Antibiotic-associated diarrhea (AAD) is a common and unintended adverse effect of antibiotic treatment. It is characterized by the disruption of the gut microbiota, decreased intestinal short chain fatty acid (SCFA) concentrations, accumulation of luminal carbohydrates and colonic bile acids, altered water absorption, and ultimately diarrhea. Probiotics were shown to prevent AAD in numerous clinical trials.

Heterogeneous antimicrobial activity in broncho-alveolar aspirates from mechanically ventilated intensive care unit patients.
