Prevalence and Predictors of Pulmonary Tuberculosis among Prison Inmates in Sub-Saharan Africa: A Systematic Review and Meta-Analysis.

Introduction: Prisoners in Sub-Saharan Africa (SSA) are at a high risk of tuberculosis (TB) infection due to overcrowding and poor ventilation. Consequently, TB is a leading cause of morbidity and mortality in prison, and many inmates face a number of barriers to TB control and had limited information in the region. Thus, the aim of this systematic review and meta-analysis was to estimate the overall pooled prevalence of pulmonary TB and predictors among prison inmates in SSA. Methods: From 2006 to 2019, a systematic review and meta-analysis was conducted using various databases, including PubMed, Embase, Web of Science, and Scopus. The data were extracted in Microsoft Excel using a standardized data extraction format, and the analysis was carried out with STATA version 14. To detect heterogeneity across studies, the I2 and the Cochrane Q test statistics were computed. To determine the overall prevalence of TB and predictors among prison populations, a random effect meta-analysis model was used. Results: Of the 3,479 retrieved articles, 37studies comprising 72,844 inmates met the inclusion criteria. The pooled prevalence of pulmonary TB among prison inmates in SSA was 7.74% (95% CI: 6.46-8.47). In the subgroup analysis, the highest prevalence was found in the Democratic Republic Congo (DRC) (19.72%) followed by Zambia (11.68%) and then Ethiopia (9.22%). TB/HIV coinfection (OR 4.99 (95% CI: 2.60-9.58)), Body mass index (BMI < 18.5) (OR 3.62 (95% CI: 2.65-6.49)), incarceration (OR 4.52 (95% CI: 2.31-5.68)), and previous TB exposure (OR 2.43 (95% CI: 1.61-3.56)) had higher odds of pulmonary TB among inmates. Conclusion: The prevalence of pulmonary TB among SSA prison inmates was found to be high as compared to total population. TB/HIV coinfection, BMI, incarceration duration, and TB exposure were all predictors with pulmonary tuberculosis in prison inmates. As a result, emphasizing early screening for prisoners at risk of pulmonary TB is an important point to achieving global TB commitments in resource-limited settings.

Determination of the indoor air bacterial profile in Jimma University Specialized Hospital, Southwest Ethiopia.

Objective: Microorganisms are one of the main indoor air contaminants. In a hospital setting, a range of hospital-acquired infectious diseases are caused due to indoor air pollution. Studies conducted on hospital patients and healthcare workers revealed that indoor air pollution is causing more severe health problems than outdoor air pollution. Thus, this study aimed to determine the bacterial indoor air quality in Jimma University Specialized Hospital in southwest Ethiopia. Method: An institution-based cross-sectional study was conducted from late May to October 2020. Indoor air samples were collected through a passive method by exposing prepared sample plates for prescheduled exposure time, and bacterial species were identified using morphology and biochemical tests. Result: Based on the findings, neither of the wards showed a similar microbial concentration. Among the studied wards, the minimum and the maximum bacterial distribution ranged from 280 to 6369 cfu/m3, respectively. Staphylococcus aureus, coagulase-negative spp., Klebsiella spp., Escherichia coli, Bacillus spp., Proteus spp., and Streptococcus spp. were bacterial isolates. Statistically, the concentration of the bacteria in all the studied wards was tested significantly different (p ⩽ 0.001). Conclusion: Among studied wards, the emergency outpatient ward showed a maximum bacterial concentration in contrast to the minor operating room. Based on the criteria of the World Health Organization on hospital-acquired infections, studied wards were highly contaminated.

Spatio-Temporal Variation of Malaria Incidence and Risk Factors in West Gojjam Zone, Northwest Ethiopia.

Introduction: Malaria is a life-threatening acute febrile illness which is affecting the lives of millions globally. Its distribution is characterized by spatial, temporal, and spatiotemporal heterogeneity. Detection of the space-time distribution and mapping high-risk areas is useful to target hot spots for effective intervention. Methods: Time series cross sectional study was conducted using weekly malaria surveillance data obtained from Amhara Public Health Institute. Poisson model was fitted to determine the purely spatial, temporal, and space-time clusters using SaTScan™ 9.6 software. Spearman correlation, bivariate, and multivariable negative binomial regressions were used to analyze the relation of the climatic factors to count of malaria incidence. Result: Jabitenan, Quarit, Sekela, Bure, and Wonberma were high rate spatial cluster of malaria incidence hierarchically. Spatiotemporal clusters were detected. A temporal scan statistic identified 1 risk period from 1 July 2013 to 30 June 2015. The adjusted incidence rate ratio showed that monthly average temperature and monthly average rainfall were independent predictors for malaria incidence at all lag-months. Monthly average relative humidity was significant at 2 months lag. Conclusion: Malaria incidence had spatial, temporal, spatiotemporal variability in West Gojjam zone. Mean monthly temperature and rainfall were directly and negatively associated to count of malaria incidence respectively. Considering these space-time variations and risk factors (temperature and rainfall) would be useful for the prevention and control and ultimately achieve elimination.

Photovoltaic concentrator potential and its inactivation rate of indicator microorganism in point of use water treatment system.

Objective: Unsafe drinking water has a significant health impact all over the world especially, in developing countries. Household water treatments become more affordable than conventional ones for many reasons. Photovoltaic concentrator is environmentally sound and effective inactivation method by converting light energy to electricity. This study aimed to assess the inactivation potential of photovoltaic concentrator on drinking water quality indicator microorganisms at different solar exposure times. Methods: A laboratory-based experimental study was conducted at Jimma University's environmental microbiology laboratory to measure the disinfection potential of the photovoltaic concentrator for months in uneven weather conditions. A membrane filtration, a pour plate count method, and a calibrated clear sky calculator were used. Results: Among indicator microorganisms, Escherichia coli was completely inactivated (standard deviation = 11.3°C, R2 = 0.80) at 2 h of solar exposure whereas heterotrophic plate count was measured as (SD = 12.2°C, R2 = 0.82) at 35°C for 48 h in the sample that contains 2.81 NTU. Conclusion: Based on the findings, photovoltaic concentrator was one of the most effective inactivation technologies for E. coli and total coliform.

Prevalence of active trachoma and associated factors among school age children in Debre Tabor Town, Northwest Ethiopia, 2019: a community based cross-sectional study.

BACKGROUND: Trachoma is an infectious eye disease caused by Chlamydial trachomatis. It is a major health problem in poor nations, notably in Sub-Saharan Africa. Despite the severity of the problem, there was a scarcity of data on trachoma prevalence and associated factors among school-aged children in Debre Tabor town following SAFE and MDA. OBJECTIVES: The goal of this study was to determine the prevalence of active trachoma and its associated factors among school-aged children in Debre Tabor, Northwest Ethiopia, in 2019. METHODS: A community-based cross-sectional study was used among school-aged children. Structured interview questionnaires, an observational checklist, and a physical examination were used to collect data from study participants who were chosen using a systematic random sampling procedure. IBM SPSS 20 was used to enter data, which was then transferred to IBM SPSS 20 for bivariate and multivariable logistic regression analysis. RESULT: A total of 394 children aged 5-15 had been screened and took part in the study, with 9.9% (95% CI: 6.9, 12.7) testing positive for active trachoma. Having an unimproved larine type (AOR = 5.18; 95%CI: 1.96, 13.69), improper solid waste disposal (AOR = 3.026; 95%CI: 1.17, 7.8), family size greater than four (AOR = 3.4; 95%CI: 1.22, 9.49), not using soap for face washing (AOR = 4.48; 95%CI: 1.46, 13.72) and an unclean face of the child during examination (AOR = 23.93; 95%CI: 8.25, 69.38) were found to be significant predictors of active trachoma. CONCLUSION: Active trachoma among school-age children was high compared to the WHO's definition of trachoma as a public health problem. A family size of four, poor solid waste management, an unimproved type of latrine, an unclean child's face, and not using soap when washing one's face were all significant predictors of active trachoma. Promotion of behavioral determinants through health education programs like keeping facial cleanliness by washing their child's face with soap, managing solid waste properly, and installing improved latrines to reduce active trachoma needs to be in place.

Food hygiene practice and its associated factors among food handlers working in food establishments during the COVID-19 pandemic in East Gojjam and West Gojjam Zones, North West Ethiopia.

OBJECTIVES: This study was aimed to assess the food hygiene practice and associated factors among food handlers working in food establishments during the COVID-19 pandemic in East Gojjam and West Gojjam Zones, North West Ethiopia. METHODS: A facility-based cross-sectional study was conducted among 845 food handlers working in 423 selected food establishments of East and West Gojjam Zones from 22 September to 2 November 2020. The food handlers were categorized as a cooker and a waiter based on their responsibility. A data collection tool was adapted from the literature and validated by conducting a pre-test prior to the study. Binary logistic regression was done to identify the factors associated with food hygiene practice among food handlers. RESULTS: The prevalence of poor food hygiene practices among food handlers working in food establishments was 51.2% (95% confidence interval = 47.8, 54.6%). Being both a cooker and waiter (adjusted odds ratio = 2.98; 95% confidence interval = 1.02, 8.66), availability of personal protective equipment (adjusted odds ratio = 2.67; 95% confidence interval = 1.75, 4.08), presence of pipe water in the kitchen (adjusted odds ratio = 2.73; 95% confidence interval = 1.84, 4.06), presence of a supervisor (adjusted odds ratio = 2.26; 95% confidence interval = 1.41, 3.62), and separate dressing room (adjusted odds ratio = 2.69; 95% confidence interval = 1.84, 3.93) were significantly associated with food hygiene practice among food handlers. CONCLUSION: The prevalence of poor food hygiene practices among food handlers working in food establishments during the COVID-19 pandemic was high. Therefore, improving food hygiene practice focusing on availing personal protective equipment, pipe water in the kitchen, and ensuring the presence of a supervisor as well as a separate dressing room in the food establishment is recommended.

Prevalence of Neonatal Sepsis in Ethiopia: A Systematic Review and Meta-Analysis.

INTRODUCTION: Neonatal sepsis is a systemic infection occurring in infants during the first 4 weeks of life and is a major cause of mortality and morbidities of newborns due to their age-related weak and immature immune systems. In Ethiopia, despite many studies being conducted on neonatal sepsis, the reported findings are inconsistent. The aim of this study is to determine the prevalence of neonatal sepsis to enhance the utility and interpretation of the evidence. METHODS: An extensive systematic review and meta-analysis were performed to extract studies on the prevalence of neonatal sepsis in Ethiopia. The PubMed, Cochrane Library, ScienceDirect, Web of Science, and Google Scholar were systematically searched. Two independent authors selected and extracted the data from each included article. The heterogeneity of included studies was assessed using the Higgins I 2 test, and a random-effects model was performed in Stata/se Version 14. RESULTS: Eighteen studies with a sample size of 10,495 study subjects were included with a reported range of neonatal sepsis from 17% to 78%. The pooled prevalence of neonatal sepsis was 45% (95% CI: 35, 55; I 2 = 99.3%, p < 0.01). Early onset neonatal sepsis was found to have a prevalence of 75.4% (95% CI: 68.3, 82.6). Subgroup analysis in the study area (i.e., by region) was calculated revealing the highest neonatal sepsis in Amhara region at 64.4% (95% CI: 44.9, 84.0) and the lowest in Southern Nations, Nationality, and People at 28% (95% CI: 16, 40). CONCLUSION: In this review, the prevalence of neonatal sepsis in Ethiopia was found to be high, especially in terms of early onset neonatal sepsis. As a result of the findings, it is important to consider the early and optimal points for interventions to better manage the prevalence and outcomes of neonatal sepsis. Further research is needed to investigate the neonatal sepsis status at different regions and associated factors for neonatal sepsis not yet studied.
