Background: Intestinal parasitic infection has serious medical and public health impacts in developing countries. Intestinal parasites were under reported via direct wet mount method due to its poor sensitivity. So, the selection of a more sensitive and reliable diagnostic method is essential. Objective: The aim of the study was to evaluate the diagnostic performance of wet mount and concentration techniques of stool examination for intestinal parasites identification. Methods: A cross-sectional study among 797 pregnant women was conducted from October 2018 to February 2019 at Debre Markos Comprehensive Specialized Hospital. The study participants were selected by using a systematic random sampling technique. Stool sample was processed by using Wet Mount (WM) and Formol-Ether Concentration (FEC) techniques. Data was entered into Epi-data version 3.1 and analysis using SPSS version 20.0. The sensitivity, specificity, positive predictive value, and negative predictive value were determined against the combined result as “Gold” standard. Kappa value was determined to estimate the agreement of the diagnostic methods. Results: The overall prevalence of intestinal parasites (IP) was 35.2% with a combined method. By using WM and FEC the prevalence of IP was 13.1% and 25.7%, respectively. The sensitivity and negative predictive value of WM method were 37.1% and 74.6%, and for FEC method 73.5% and 87.5%, respectively. Test efficiency of direct WM and FEC were 77.9% and 90.7%, respectively. The agreement of WM and FEC techniques with combined technique were moderate (κ=0.434) and perfect (κ=0.783), respectively. Conclusion: The prevalence of intestinal parasites was under-reported by wet mount technique. The diagnostic performance of FEC technique for the diagnosis of intestinal parasites in pregnant women was notably high as compared to WM technique in the present study. Therefore, the WM and FEC combined method should be used as a routine diagnostic technique for the diagnosis of intestinal parasites identification.

Antimicrobial resistance (AMR) poses a significant global health threat by diminishing the effectiveness of once-powerful antimicrobial agents, leading to higher rates of illness and death, along with escalating healthcare costs. While bacterial resistance is a primary concern, resistance is also increasing against antifungal, antiparasitic, and antiviral drugs. Many of the last-resort drugs are becoming less effective due to AMR. Projections indicate that by 2050, AMR could cause up to 10 million deaths annually, making it the leading cause of death worldwide, a situation that could result in a post-antibiotic era with substantially increased morbidity and mortality. This review aims to raise awareness about the dangers of AMR and its potential to become a silent global pandemic. It begins by examining antimicrobial drugs, followed by a discussion on AMR, focusing on resistance to antibacterial, antifungal, antimalarial, and antiviral drugs, along with its effects on health, and the economy, and prioritized global pathogens. Finally, it explores preventive measures and innovative strategies to combat AMR.

Background: Soil-transmitted helminths are more prevalent in tropics and sub-tropics including Ethiopia. Despite their high prevalence, direct saline microscopy with its low sensitivity has been used as a diagnostic method in almost all health facilities in Ethiopia. Alternative diagnostic methods which have higher sensitivity are not yet implemented. Therefore, this study aimed to compare and evaluate the performance of diagnostic methods for soil transmitted helminths. Methods: A cross-sectional study among 520 school children was conducted from October to December, 2019 in Amhara National Regional State. The study participants were selected using systematic random sampling technique. Stool samples were processed via formol ether concentration, Kato-Katz, spontaneous tube sedimentation and agar plate culture techniques. Data was entered into Epi-data version 3.1 and analysis was done using SPSS version 20.0. The sensitivity, specificity, and negative predictive value were calculated against the combined result. Strength of agreement of the diagnostic methods was determined by Kappa value. Results: The Overall prevalence of soil transmitted helminths was 40.8% using combination of methods. The prevalence 24.4, 22.5, and 32.4%, respectively was recorded by using formol ether concentration, Kato-Katz and spontaneous tube sedimentation. The highest prevalence of hookworm (29.2%) was detected by the agar plate culture. The sensitivity and negative predictive value of formol ether concentration were 57.9 and 78.4%, for Kato-Katz thick smear 55.2 and 76.4%, for spontaneous tube sedimentation were 79.2 and 87.5% to soil transmitted helminths detection, respectively. The sensitivity and negative predictive value of agar plate culture to hookworm detection were 86.4 and 93.5%, respectively. Conclusion: Spontaneous tube sedimentation shows higher sensitivity in the detection of soil transmitted helminth infections. Agar plate culture method also indicated better performance for hookworm detection than other methods. Therefore, the employment of spontaneous tube sedimentation technique for routine laboratory and agar plate culture for research purposes will significantly aid in accurate diagnosis of parasitic infections.

Background: Although based on a single system, each laboratory should have their own quality management system, in Ethiopia, quality management systems in medical laboratories were introduced in 2009 with the aim of improving the quality of services. Objective: This review was designed to evaluate the status of quality management practice and challenges among medical laboratories in Ethiopia. Methods: A systematic qualitative review of the literature was made by searching the international electronic bibliographic database of PubMed (NML), web of science (TS), google scholar, African journals online (AJOL) and Cochrane Library. Results: Thirty-six full-text articles, which were published between 2010 and 2022, were included in this review. In this review, 33 of 36 (91.7%) studies showed that status of quality management practice in Ethiopian medical laboratories was limited. As a result, the quality of medical laboratories was inadequate. The main challenges were problems associated with laboratory professionals (35/36=97.2%), inadequate support from management bodies (21/36=58.3%), limited on-job training access (8 /36=22.2%) and high workload (5/36=13.8%). Conclusion: The status of quality management practice among medical laboratories in Ethiopia is limited. The main quality compromising factors were problems associated with laboratory professionals, inadequate support from management bodies, high workload, and limited on-job training access. Therefore, all responsible stakeholders should focus on ensuring Quality Management Systems and the system should be applied in all Medical laboratories. Only this will ensure the improvement of quality within medical laboratories across Ethiopia.

Background: Tuberculosis (TB) is a major public health problem among people living with Human Immunodeficiency Virus (HIV) in resource-limited countries like Ethiopia. Up-to-date information regarding TB co-morbidity and determinant factors among HIV sero-positive individuals is lacking in the study area. Objective: This study aimed to determine the prevalence of TB co-morbidity and their determinants among HIV sero-positive individuals in Shegaw Motta district hospital. Methods: A cross-sectional study was conducted among 326 people living with HIV from February to April 2019, in Shegaw Motta district hospital. The systematic random sampling technique was used to select the study participants. Data were entered into the EpiData version 3.1 and analysis was done using SPSS version 20.0. Results: The prevalence of TB/HIV co-infection was 18.1%. TB/HIV patients whose drunk alcohol (AOR=2.36, 95% CI=1.07– 5.19), BMI< 16 (AOR= 19.13, 95% CI=4.14– 88.36), and BMI ranges between 16 and 18.5 (AOR=9.78, 95% CI=3.07– 31.19), World Health Organization (WHO) clinical stage IV (AOR=23.02, 95% CI=3.76– 140.97), WHO clinical stage III (AOR=14.36, 95% CI=3.50– 58.92), and WHO clinical stage II (AOR=4.17, 95% CI=1.34– 13.01), bedridden (AOR=13.79, 95% CI=5.44– 34.95) and ambulatory functional status (AOR=5.30, 95% CI=1.87– 15.05) were significant predictors for TB/HIV co-infection. Conclusion: The prevalence of TB among HIV sero-positive individuals is high. Determinant factors, including drinking alcohol, BMI, WHO clinical stage and functional status, were significant predictors for TB/HIV co-infections. Therefore, diagnosis of TB among sero-positive individuals should be strengthened in health institutions.

Objective: To assess the prevalence and associated factors of soil transmitted helminths (STHs) among Endemata primary school in North West Ethiopia, 2021. Methods: A cross-sectional study with 195 school children was conducted from May to July 2021 at Endemata primary school. The study participants were selected by using systematic random sampling technique. Stool samples were processed via direct wet mount and formol-ether concentration techniques. Data was entered by Epi-Dara version 3.1 and data analysis was done using SPSS version 20.0. Variables were considered to be statistically significant if P<0.05 at 95% confidence level. Results: The overall prevalence of STHs was 10.8% (95% CI 7.1-16.0). The prevalence of Ascaris lumbricoides, hookworm and Trichuris trichiura were 5.6% (95% CI 3.1-9.9), 3.1% (95% CI 1.3-6.7) and 2.1% (95% CI 0.6-5.3), respectively. Grade 1-4 students were more likely to get infected with STHs as compared to grade 5-8 students (adjusted OR 4.7, 95% CI 1.3-16.6). Students who did not have latrines at their home were at higher risk to develop STHs infection comparing with those who had latrine at their home (adjusted OR 5.0, 95% CI 1.7-15.2). Similarly, the school children who did not wear shoes were more likely to be infected by STH parasite than those who did it (adjusted OR 6.3, 95% CI 1.9-20.7). The odds of being infected by STH parasites in children who did not trim their fingernails were 4.9 as compared to those who did it (adjusted OR 4.9, 95% CI 1.5-15.7). Conclusions: The prevalence of STHs among Endemata primary school children was low. Student grade level, latrine availability, shoes wear and nail status were significantly associated with STHs infection. Therefore, we recommend policy makers and stakeholders to follow the integration of deworming with water, hygiene and sanitation as well as the consistent health education of school children to control and prevent STH infections.
