This study explored the impact of stakeholder engagement on curriculum implementation at Ethiopian Defense University (EDU). It focuses on examining the effects of partnerships, stakeholder motivation, and decisionmaking on curriculum implementation. As a result, a descriptive survey research design with a mixed research approach was employed. A total of 166 respondents (109 students, 51 instructors, and six college commandants) were the participants of the study. Commandants were selected by purposive sampling, and instructors and students were selected randomly. Questionnaires and interviews were tools or sources of data. The quantitative data were analyzed using descriptive statistics (frequency, percentage, mean, and standard deviation) and inferential statistics (one-way ANOVA and independent samples t-test), whereas the qualitative data were analyzed through verbal description. Findings revealed that instructors value stakeholders' support and commitment, while students appreciate the positive impact on their learning experience. The finding revealed that there is a strong positive correlation between stakeholder engagement and curriculum implementation effectiveness, emphasizing the importance of continuous interaction, feedback collection, and stakeholder knowledge for curriculum alignment. It also emphasizes the need for stakeholder engagement in decision-making processes and partnerships to improve curriculum implementation outcomes. The findings of the study may inspire further research and dialogue on stakeholder engagement in curriculum implementation, encouraging international audiences to explore innovative approaches and best practices that promote meaningful educational experiences for students in the field of pedagogy. The researcher suggested that EDU should prioritize stakeholder motivation, partnerships, and decision-making for effective curriculum implementation. This promotes ownership, engagement, and shared responsibility. Additionally, EDU should prioritize stakeholder engagement, support, understanding, commitment, and feedback to ensure the quality and effectiveness of curriculum implementation.

While computer animations have the potential to assist learners in understanding difficult concepts and eliminating misconceptions, studies supporting this claim are scarce. This study investigated how the 7E instructional model integrated with computer animations affected students' conceptual understanding and misconceptions about food making and plant growth. Experimental groups were taught the 7E learning cycle model [7E LCM], and 7E LCM with computer animation [CA] while the control group was taught the conventional instruction method. A two-tiered conceptual understanding multiple-choice test and semi-structured interviews were used to collect the data. ANOVA analysis revealed no significant differences between groups or genders in pre-food making and growth in plant conceptual understanding [pre-FMGPCU] and pre-misconceptions test scores [pre-MC]. There were, however, significant differences in post-FMGPCU and post-MC mean scores, with the 7E LCM with CA showing better results in improving conceptual understanding and minimizing misconceptions. MANOVA revealed no statistically significant difference between male and female students' post-FMGPCU and post-MC results. It was concluded that the 7E LCM with CA enhances students' conceptual understanding and minimizes misconceptions more effectively than other instructional approaches. It is recommended that similar designs be used in biology teaching.

The study evaluated the suitability of primary school teachers' professional development policy implementation conceptualization of targets, reflective contents, process, methods and contexts in which it occurs in Oromia. The researchers used a mixed method with concurrent triangulation design. The researchers selected a total of 618 samples of the study using different sampling techniques such as purposive, convenience, stratified and simple random sampling techniques. The data were collected from primary sources of data such as teachers, mentors, principals, supervisors, coordinating committees and parents using questionnaires, interview, focus group discussion, document examination and observation. Then, the researchers analyzed the data using mean, standard deviation, one-way ANOVA and post hock test, and thematic narration. The study showed that both veteran and novice teachers were less able to conceptualize and contextualize their professional development practices to the existing phenomena in the schools under investigation. Teachers' professional development practices were powerless to update professional competencies and improve professional and innovative pedagogical practices in classrooms. In addition, the professional development contents and activities were repetitive from time to time. Primary school teachers were not learning proficiently from continuous professional development practices to ensure basic and specific professional competencies required in classrooms. The implementations of reflective activities such as action researches, classroom observation, differentiate learning; collaborative learning, microteaching and lesson studies couldn't contribute to practical changes. Teachers weren't actively participating in professional development because of lack of conceptualization and contextualization of reflective activities to improve professional competencies although they are transformative intellectuals. Therefore, teachers, mentors, principals, and cluster supervisors should use face-to-face learning and digital learning strategies to improve instructional practices in classrooms, and values and prestige of teaching profession. Likewise, the study forecasts the requirement of context specific policy framework and practical toolkit for newly deployed and experienced teachers rather than focusing on the generic policy document.

This study investigates the impact of Medicaid expansions, including those implementedas part of the Affordable Care Act (ACA), on reducing Black-White inequalities in augmentedincome poverty in the United States from 2009 to 2019. Utilizing bi-annual individual-levelpanel data for approximately 8,100 Black and White individuals under age 65, the study employsa method of monetizing Medicaid and Medicare benefits to recalculate household income,adjusting for taxes, transfers, tax credits, and household size. This recalculated "augmented"income provides a basis for assessing relative and anchored poverty levels. Despite initialconcerns that Medicaid expansions might exacerbate Black-White poverty disparities—givenWhite individuals' growing advantage in residing in states that expanded Medicaid—the studyprovides evidence to the contrary. Descriptive analyses indicate a decline in Black-Whiteinequalities in augmented relative poverty over the study period, with both Black and Whitepoverty rates decreasing. This reduction is attributed partly to the ACA's role in expandingMedicaid and health insurance coverage more broadly, which led to significant decreases in theuninsured rates among both Black and White populations. Further analysis reveals that Medicaidexpansion significantly increased the value of health insurance for Black individuals compared toWhite individuals, contributing to the reduction in poverty inequalities. The study concludes thatwhile Medicaid expansions reduced Black-White inequalities in poverty, they did notsignificantly reduce overall poverty for all individuals, underscoring the targeted impact of thesepolicy interventions on reducing racial disparities in poverty.

Although primary studies have reported the safety and efficacy of LITT as a primary treatment in glioma, they are limited by sample sizes and institutional variation in stereotactic parameters such as temperature and laser power. The current literature has yet to provide pooled statistics on outcomes solely for primary brain tumors according to the 2021 WHO Classification of Tumors of the Central Nervous System (WHO CNS5). In the present study, we identify recent articles on primary CNS neoplasms treated with LITT without prior intervention, focusing on relationships with molecular profile, PFS, and OS. This meta-analysis includes the extraction of data from primary sources across four databases using the Covidence systematic review manager. The pooled data suggest LITT may be a safe primary management option with tumor ablation rates of 94.8% and 84.6% in IDH-wildtype glioblastoma multiforme (GBM) and IDH-mutant astrocytoma, respectively. For IDH-wildtype GBM, the pooled PFS and OS were 5.0 and 9.0 months, respectively. Similar to rates reported in the prior literature, the neurologic and non-neurologic complication rates for IDH-wildtype GBM were 10.3% and 4.8%, respectively. The neurologic and non-neurologic complication rates were somewhat higher in the IDH-mutant astrocytoma cohort at 33% and 8.3%, likely due to a smaller cohort size.

BACKGROUND: Superior Semicircular Canal Dehiscence (SSCD) is a dehiscence of the otic capsule which normally lies over the superior semicircular canal. This database constitutes the largest series of SSCD patients to date. OBJECTIVE: To determine what preoperative factors, if any, contribute to postoperative outcomes and evaluate symptom resolution in a large SSCD patient cohort. METHODS: A single-institution, retrospective chart review collected patient demographics, intraoperative findings, and pre-and postoperative symptoms. Fishers exact t-test was performed for unpaired categorical variables, with a significance level of p

Quantifying the temperature sensitivity of methane (CH4) production is crucial for predicting how wetland ecosystems will respond to climate warming. Typically, the temperature sensitivity (often quantified as a Q10 value) is derived from laboratory incubation studies and then used in biogeochemical models. However, studies report wide variation in incubation-inferred Q10 values, with a large portion of this variation remaining unexplained. Here we applied observations in a thawing permafrost peatland (Stordalen Mire) and a well-tested process-rich model (ecosys) to interpret incubation observations and investigate controls on inferred CH4 production temperature sensitivity. We developed a field-storage-incubation modeling approach to mimic the full incubation sequence, including field sampling at a particular time in the growing season, refrigerated storage, and laboratory incubation, followed by model evaluation. We found that CH4 production rates during incubation are regulated by substrate availability and active microbial biomass of key microbial functional groups, which are affected by soil storage duration and temperature. Seasonal variation in substrate availability and active microbial biomass of key microbial functional groups led to strong time-of-sampling impacts on CH4 production. CH4 production is higher with less perturbation post-sampling, i.e. shorter storage duration and lower storage temperature. We found a wide range of inferred Q10 values (1.2-3.5), which we attribute to incubation temperatures, incubation duration, storage duration, and sampling time. We also show that Q10 values of CH4 production are controlled by interacting biological, biochemical, and physical processes, which cause the inferred Q10 values to differ substantially from those of the component processes. Terrestrial ecosystem models that use a constant Q10 value to represent temperature responses may therefore predict biased soil carbon cycling under future climate scenarios.

Abstract Background Poor dietary choices and consumption of unhealthy foods are major determinants of malnutrition among adolescents in Ethiopia. The school food environment is a valuable setting for exploring adolescents’ eating habits. Teachers have an important role in understanding factors that impact students’ dietary choices. The aim of this study is to explore secondary school teachers’ perceptions towards adolescents’ dietary habits in Ethiopia. Methods The study employed a qualitative research design. Four focus group discussions, involving a total of 13 teachers, were conducted at governmental and private schools in Addis Ababa, Ethiopia. Additionally, observations of the food environment in these four schools. The transcripts from the focus group discussions and photographs from observations were analyzed using thematic analysis. Triangulation of data sources and persistent observation of the data were employed to enhance the study’s trustworthiness. The study was approved by the Norwegian Center for Research Data and the Addis Ababa Health Bureau, and all participants provided informed consent. Result Teachers perceived adolescents’ dietary habits as unhealthy, characterized by the consumption of unsafe foods, limited variety, and reliance on processed foods. Factors negatively influencing adolescents’ dietary habits include a lack of awareness about a healthy diet among both students and parents. Low familial income levels were also identified as a barrier to eating a healthy diet. The unavailability of healthy foods and the advertising of unhealthy and processed foods as well as peer influence were hindrances to a healthy diet both at school and home. Conclusion This study provides additional evidence of the nutrition transition which is linked to the double burden of malnutrition among adolescents in low-income countries. Factors affecting adolescent diets at school are multileveled. Incorporating nutrition education into the school curriculum will likely improve dietary awareness mitigating peer influence. Regulating the school food environment and enforcing advertisement laws targeting adolescents can promote healthier school food environments. Providing short term nutrition trainings for biology or science teachers and strengthen their role in delivering nutrition education to children and their families, along with implementing measures to address food insecurity and restricting availability of unhealthy food at school need to be regarded as priorities.

Abstract The issue of missed nursing care is a problem that affects the overall quality of nursing care in hospitals around the world. However, there is limited research about it in Ethiopia. This study assessed missed nursing care and factors among nurses. An institutional-based cross-sectional study was conducted among 485 nurses at the University of Gondar Specialized Hospital. The data were collected from May 15 to June 15, 2022 using a self-administered questionnaire. A simple random sampling technique was used to select study participants. The data was entered to EPI DATA version 4.6 and exported to SPSS version 23 for analysis. Descriptive statistics were computed, and a summative score of missed nursing care was calculated. Then, multiple linear regression analysis was used to identify the factors. A P-value of 0.05 was used to declare significant level. In this study, missed nursing care was 62.5% (95% CI 60.98–64.02). Documentation, vital signs assessment, intravenous care, and assessment as per hospital policy and patient education were the most frequently missed nursing care. Being single in marital status (B = −4.609, P = 0.004), adequacy of nursing staff (B = −2.458, P = 0.003), satisfaction with income (B = −8.753, P = 0.007), working in medical unit (B = −5.708, P = 0.002) and working in both day and night shift (B = 1.731, P = 0.027) were statistically associated factors. More than half of the participants missed basic nursing care. Most of the identified factors correlated with missed nursing care negatively. Efforts should be done to enhance communication between health team members, assign a manageable number of patients per nurse, and adjust shifts and units.

Abstract Background Peste des Petits Ruminants (PPR) is a highly contagious viral disease primarily affecting goats and sheep, with clinical manifestations ranging from peracute disease to subclinical infection, particularly in atypical hosts such as cattle. The role of atypical hosts such as cattle to the spread of PPR remains controversial, with conflicting reports in the literature. Despite its worldwide significance, considerable knowledge gaps exist regarding the pathogenesis and clinical progression in both primary and atypical hosts. This study aimed to elucidate the tissue tropism, pathogenesis, virus shedding, clinical progression, and pathology associated with experimental PPR virus infection in indigenous goats and cattle. To this end, 32 animals—16 goats and 16 cattle—were intranasally inoculated with the Ethiopia/Habru/2014 Lineage-IV strain of the PPR virus followed by detailed clinical evaluations and systematic sampling at pre-established intervals to assess serological conversion, viral shedding, and the pathogenesis of the infection across both species. Results The results show that goats exhibited typical clinical signs 4 days post-inoculation, with seroconversion by day 6 and early detection of viral RNA in swabs and tissues by day 3 and virus isolation starting day 4. In contrast, cattle exhibited minimal clinical signs, with seroconversion occurring at day 8 with viral RNA detected in tissue samples at day 4 and virus isolation starting day 6 in tissues and in a single nasal swab at day 8. Clinical scores and tissue positivity rates significantly differed between goats and cattle (P = 0.007 and P

Abstract Background Sub-Saharan Africa (sSA) continues to rank among the regions in the world with the highest rates of maternal mortality and the lowest rates of utilization of maternal health care. The risk of death for women in sSA is 268 times higher than that of women in high-income nations. Adequate antenatal care (ANC) services utilization is essential to the mother's and the baby's survival and well-being. This study aimed to identify both individual and community-level factors associated with adequate antenatal care services utilization in sSA. Method We used data from the most recent Health and Demographic Surveys (DHS), which were carried out between 2012 and 2022 in 33 sSA countries. A total of 240,792 women were included in this study. The two-level mixed-effects logistic regression model was used to identify the individual and community-level factors associated with the use of adequate ANC service. Results The pooled prevalence of adequate ANC service utilization in sSA was 55.48% (95% CI: 55.28–55.68). The study showed that secondary and above-educated women (AOR = 2.13, 95% CI 2.07–2.19, secondary and above-educated husbands (AOR = 1.55, 95% CI 1.51–1.60), rich women AOR = 1.26, 95% CI 1.24–1.29), women 35–49 years of age (AOR = 1.36, 95% CI 1.32–1.41) and distance to a health facility is not a big problem (AOR = 1.13; 95% CI 1.11–1.16) was significantly and positively correlated with the use of adequate ANC services. However, rural women (AOR = 0.80; 95% CI 0.78–0.82), not having mass media access (AOR = 0.74, 95% CI 0.72–0.75), 5 and above birth order (AOR = 0.73, 95% CI 0.68–0.78) were significantly and negatively correlated with the use of adequate ANC services. Additionally, the random effects model showed that variables at the community and individual levels were responsible for approximately 62.60% of the variation in the use of adequate ANC services. Conclusion The sSA countries had a low prevalence of adequate utilization of ANC with a significant variation among countries. Moreover, public health initiatives should focus on rural women, poor women, and uneducated women to enhance maternal health services utilization. Furthermore, policies and programs that address cluster variations in the utilization of adequate ANC services must be developed, and their implementation must be vigorously pursued.

Abstract Background Road traffic accidents (RTAs) are a pressing public health issue in Ethiopia, exacerbated by rapid urbanization and motorization. Despite efforts, escalating rates persist due to various factors like human behavior and road infrastructure deficiencies. This study addresses the need for comprehensive data on RTAs in Ethiopia, aiming to uncover socioeconomic and behavioral factors to inform evidence-based policies. Methods A systematic review and meta-analysis were conducted from March to April 2024, adhering to PRISMA guidelines. Major databases like Google Scholar, PubMed, and the Cochrane Library were searched using specific keywords related to RTAs and Ethiopia. Studies conducted between 2014 and 2024 were included, with eligibility criteria. Data extraction followed a standardized Microsoft Excel format. Study quality was assessed using the JBI checklist, with high-quality articles included. Statistical analysis, conducted using STATA version 17, included descriptive analysis, forest plots for RTA prevalence, and examination of publication bias using Egger and Begs tests. Subgroup analysis and meta-regression explored moderating factors and sources of heterogeneity. Results The systematic review identified eight studies meeting inclusion criteria, conducted between 2014 and 2022. RTA prevalence was 36% (95% CI: 23; 49). Sensitivity analysis confirmed the robustness of the estimated prevalence. Publication bias was detected via Egger’s test, though Begg’s test was non-significant. Meta-regression found no significant influence of publication year or sample size on RTA prevalence. Socioeconomic factors like income level and driving experience, alongside behavioral factors like traffic rule violations and substance use, were identified as key drivers of RTAs in Ethiopia. Conclusions The study highlights the significant burden of road traffic accidents in Ethiopia, influenced by socioeconomic and behavioral factors. Socioeconomic factors such as income level and driving experience, along with behavioral factors like traffic rule violations and substance use, emerged as prominent determinants of RTAs. Policymakers should prioritize evidence-based interventions targeting these factors to improve road safety nationwide.

Abstract The parabolic convection-diffusion-reaction problem is examined in this work, where the diffusion and convection terms are multiplied by two small parameters, respectively. The proposed approach is based on a fitted operator finite difference method. The Crank-Nicolson method on uniform mesh is utilized to discretize the time variables in the first step. Two-point Gaussian quadrature rule is used for further discretizing these semi-discrete problems in space, and the second order interpolation of the first derivatives is utilized. The fitting factor’s value, which accounts for abrupt changes in the solution, is calculated using the theory of singular perturbations. The developed scheme is demonstrated to be second-order accurate and uniformly convergent. The proposed method’s applicability is validated by two examples, which yielded more accurate results than some other methods found in the literatures.

Abstract Background Globally, extended-spectrum beta-lactamase-producing and carbapenem-resistant Enterobacterales are major causes of hospital-acquired infections and there are increasing concerns about their role in community-acquired infections. Objective We aimed to investigate the prevalence of extended-spectrum beta-lactamase-producing Enterobacterales (ESBL-PE) and Carbapenemase-producing-Carbapenemresistant-Enterobacterales (CP-CRE) and associated factors in community settings in Gulele sub city, Addis Ababa, Ethiopia. Methods A cross-sectional study was conducted among 261 healthy individuals. Stool samples were collected and processed using standard microbiological methods. Antimicrobial susceptibility and phenotypic ESBL and carbapenemase tests were performed. Antibiotic resistance genes were detected by Polymerase Chain Reaction (PCR). Results The colonization rate of ESBL-PE and CP-CRE were 31.4% (82/261, 95% CI: 25.91–37.48) and 0.8% (2/261, 95% CI: 0.13–3.1), respectively by phenotypic method. Molecular detection of genes for ESBL-PE was 27.9% (73/261, 95% CI:22.7–33.9), and for CP-CRE was 0.8% (2/261, 95% CI: 0.13–3.1). The most prevalent genes were blaTEM [76.7% (56/73)] and blaCTX-M [45.2% (33/73)]. Previous antibiotic use (AOR:2.04, 95%CI: 1.35–4.41, P:0.041) and age between 42 and 53 years old (AOR:3.00, 95%CI:1.12–7.48, P:0.019) were significantly associated with ESBL-PE colonization. Conclusion Intestinal colonization by ESBL-PE harboring the associated antibiotic resistance genes was substantially high but with low CP-CRE. Continued surveillance of community-level carriage of antimicrobial resistance Enterobacterales is warranted.

Abstract Background and objective Urolithiasis, the presence of stones in the urinary tract, has been linked to various clinical features and reported as a worldwide health concern. Its prevalence varies across different regions as well as populations. Several primary studies have been conducted in Sub-Saharan Africa on the situation. However, their reports are inconsistent. Hence, this review aimed to assess the pooled magnitude of urolithiasis and its clinical patterns among hospital-visiting patients in sub-Saharan Africa. Methods Online databases such as PubMed, Hinari, the African Journals online database, and Google Scholar were used to comprehensively search articles published until June 28, 2023, about the prevalence and clinical patterns of urolithiasis in Sub-Saharan Africa. All the included studies were conducted at hospital setting. The retrieved data was exported to STATA version 16 for final analysis. A random-effect meta-analysis model was computed to estimate the pooled results. The heterogeneity of the studies was assessed using I 2 and Cochran’s Q. Publication bias was examined by observation using funnel plots and statistically by Egger’s tests. Subgroup analysis was performed based on the country where the studies have been conducted. Result A total of 26 articles (11 reported both prevalence and clinical pattern, 5 reported only prevalence, and 10 reported only clinical patterns of urolithiasis) were included in the final systematic review and meta-analysis. The pooled prevalence of urolithiasis among hospital-visiting patients was 9.4% (95% CL = 4.9–14%), with significant heterogeneity. Most of the urolithiasis was located in the kidney, with an estimated pooled proportion of 4.6% (95% CI = 2.7, 6.5), followed by bladder stone-2.0% (95% CI = 0.7, 3.4), ureteral stone-1.8% (95% CI = 0.7, 2.9), and urethral stone-0.2% (95% CI = 0.00, 0.05). The subgroup analysis showed the highest prevalence of urolithiasis was found in Mauritian, 28.1% (95%CI 24.5, 31.7), followed by Ethiopia 18.1%, and the lowest was in Eritrea, 1.0%. A sensitivity analysis using the random-effects model found no influential study on the pooled prevalence of urolithiasis. Evidence of significant publication bias was observed and trim-fill analysis was conducted for adjustment. Accordingly, two missing studies were identified, and after adjustment, the combined prevalence of urolithiasis was estimated to be 10.7%. The study also found that urolithiasis prevalence per gender was 6.3% in males and 2.9% in females. The most common clinical presentation of urolithiasis was flank pain at 58.4% (95% CL=, 45.9, 70.8), followed by low back pain at 45.9% (95% CL=, 23.1, 68.8), and nausea/vomiting at 29.9% (95% CI: 1 1.1, 48.8). Conclusion The prevalence of urolithiasis in Sub-Sahara African Countries is increasing even though a remarkable regional variation was observed, with higher predominance in males than females. Common clinical presentations of urolithiasis were flank pain, low back pain, and nausea/vomiting.

Abstract Improper solid waste management in urban and semi-urban areas has led to adverse impacts on the environment, public health, and the economic well-being of communities. Therefore, this study analyzes the status of household solid waste management practices and their effects in Logia Town, Afar, Ethiopia. To achieve this objective, the study utilizes both descriptive and econometric models (binary logistic regression model). The descriptive results of the study revealed that there is general awareness of the importance of solid waste management (SWM) and its impact on the environment, economy, and human health among the respondents. Regarding respondents’ attitudes, the majority of households understand the responsibility of proper waste disposal and its impact. However, in terms of solid waste management practices, 80% of households do not properly segregate their waste, 59.3% do not separate solid waste (SW) before disposal, and 74% of households engage in improper disposal practices. About 95.9% of respondents were aware that improper waste management can lead to diseases such as diarrhea, typhoid, and cholera. Around 65% of the sampled households considered solid waste as a source of wealth, and, as a result, 56% of them reuse, recycle, and reduce waste. This indicates that solid waste has economic value for society. Regarding the environmental impact of SW, about 89% of respondents argued that SW adversely affects the environment by polluting rivers, lakes, wells, and air. This environmental impact negatively affects the well-being and economic status of the community. The binary logistic regression model found that having adequate solid waste landfills, access to door-to-door solid waste collection, knowledge of SWM rules and regulations, treating waste as a resource, and understanding the 3Rs (recycle, reuse, reduce) had positive and significant effects on the adoption of proper solid waste management practices in the study area. Therefore, to reduce undesirable effects and improve the value of SW, the relevant authorities should provide adequate solid waste landfills and door-to-door collection services, create awareness about SWM rules and regulations, and promote knowledge of the 3Rs.

Abstract Background The principal route of HIV infection in children is vertical transmission. Thus, this study aimed to assess the incidence of mother-to-child transmission of HIV and predictors of positivity among HIV-exposed infants. Method Institutions-based retrospective follow-up study was conducted in South Gondar Public hospitals, Northwest Ethiopia from December 2019 to November 2021. The data were taken from PMTCT logbooks and patient medical records, with death being the competing event. Data were entered in to Epi info version 7 and exported to STATA version 14 for final analysis. Both bivariable and multiple variable proportional subdistribution hazard analysis were conducted to identify predictors. P-value

Abstract Background Ensuring the availability of safe drinking water remains a critical challenge in developing countries, including Ethiopia. Therefore, this paper aimed to investigate the prevalence of fecal coliform and E. coli bacteria and, geographical, children availability, and seasonal exposure assessment through a meta-analysis. Methods Two independent review groups extensively searched internet databases for English-language research articles published between 2013 and 2023. This systematic review and meta-analysis followed PRISMA guidelines. The methodological quality of each included study was evaluated using the STROBE guidelines. Publication bias was assessed by visual inspection of a funnel plot and then tested by the Egger regression test, and meta-analysis was performed using DerSimonian and Laird random-effects models with inverse variance weighting. Subgroup analyses were also conducted to explore heterogeneity. Results Out of 48 potentially relevant studies, only 21 fulfilled the inclusion criteria and were considered for meta-analysis. The pooled prevalence of fecal coliform and E. coli was 64% (95% CI: 56.0–71.0%, I 2 = 95.8%) and 54% (95% CI: 45.7–62.3%, I 2 = 94.2%), respectively. Subgroup analysis revealed that the prevalence of fecal coliform bacteria increased during the wet season (70%) compared to the dry season (60%), particularly in households with under-five children (74%) compared to all households (61%), in rural (68%) versus urban (66%) areas, and in regions with high prevalence such as Amhara (71%), Gambela (71%), and Oromia (70%). Similarly, the prevalence of E. coli was higher in households with under-five children (66%) than in all households (46%). Conclusions The analysis highlights the higher prevalence of fecal coliform and E. coli within households drinking water, indicating that these bacteria are a significant public health concern. Moreover, these findings emphasize the critical need for targeted interventions aimed at improving drinking water quality to reduce the risk of fecal contamination and enhance public health outcomes for susceptible groups, including households with under-five children, in particular geographical areas such as the Amhara, Gambela, and Oromia regions, as well as rural areas, at point-of-use, and during the rainy season. Registration This review was registered on PROSPERO (registration ID - CRD42023448812).

Abstract Introduction Post-traumatic stress disorder (PTSD) is a prevalent challenge faced by individuals following traumatic events. Given the substantial impact of PTSD on the well-being of young people, comprehensive assessment of the available evidence can inform more effective prevention and intervention strategies to support the mental health and resilience of children in the African context. Despite its high incidence, there has been no up-to-date systematic synthesis of evidence to measure the magnitude of PTSD in pediatric populations in Africa. This systematic review and meta-analysis aim to quantify the prevalence of PTSD and identify associated factors in this vulnerable population. Methods A systematic search was conducted across multiple databases, including PubMed, Embase, Scopus, Science Direct, and the search engines Google Scholar and Google, covering the period from 2014 up to May 15, 2024. The primary objective of this search was to identify relevant studies. Subsequently, a meta-analysis was performed using random-effects models to estimate the pooled effect size for each outcome of interest. Additionally, subgroup analysis was conducted to explore potential sources of heterogeneity, with study characteristics considered as covariates. Results The pooled prevalence estimate for post-traumatic stress disorder (PTSD) among pediatric individuals was 36% (95% CI: 28–44%). Notably, significant heterogeneity existed among the studies (I2 = 98.41%, p value

Abstract Introduction The use of unimproved energy sources is associated with a range of health problems. However, in Ethiopia, studies focused on the utilization of unimproved energy sources and associated factors are limited. Therefore, this study aimed to close this gap. Methods In this community-based cross-sectional study, 5,350 participants were enrolled. Multivariable logistic regression analyses were employed to examine the associations between the utilization of unimproved energy sources and the predictor variables. Additionally, the chi-square test was used to examine the association between households' unimproved energy source utilization and the occurrence of health problems. Results In this study, 45% of households used unimproved energy sources. In the multivariable analysis, households headed by men (adjusted odds ratio [AOR] = 0.76; with 95% confidence interval [CI] 0.66, 0.87), households headed by illiterate heads (AOR = 1.77 with 95% CI 1.47, 2.14), household family size (AOR = 0.79 with 95% CI 0.79, 0.93), households headed with farmers (AOR = 3.33 with 95% CI 2.31, 4.81), households with low income (AOR = 3.41 with 95% CI 2.57, 4.51), rural households (AOR = 7.94 with 95% CI 6.76, 9.32), and households with regular coffee ceremony practices (AOR = 1.17 with 95% CI 1.00, 1.36) were significantly associated with the utilization of unimproved energy sources. Additionally, the results of the chi-square test revealed that households that relied on unimproved energy sources had a 1.5-fold greater risk of developing respiratory illnesses, an 8.5-fold greater risk of developing cataract disease, and a 5.2-fold greater risk of developing trachoma than households that used improved energy sources. Conclusion A significant proportion of households in Bishoftu town still rely on unimproved energy sources for cooking and other household needs. This indicates a substantial challenge in achieving universal access to clean and sustainable energy in the area. Several socioeconomic and demographic factors are associated with the use of unimproved energy sources, including male-headed households, illiteracy of household head, smaller family size, farming occupation, low income, rural residence, and regular coffee ceremony practices. Most importantly, the use of unimproved energy sources is associated with higher risks of respiratory illnesses, cataracts, and trachoma among household members. Therefore, the government should implement targeted interventions to promote the adoption of clean and improved energy sources among vulnerable households such as households headed by farmers, those with illiterate heads, households with low socioeconomic status, households with regular coffee ceremony practices, and those in rural areas. In addition, the local government should develop and implement educational campaigns to raise awareness about the health and environmental risks associated with the use of unimproved energy sources, particularly among households with high-risk factors identified in the study.
