RESUMO
BACKGROUND: Malaria is a serious, fatal disease, and a high-risk determinant for human health globally. Children, pregnant women, and migrants are vulnerable groups for malaria infection in African regions. Recently, malaria is an endemic disease in Ethiopia. OBJECTIVES: This study aimed to determine the pooled prevalence of malaria and its determinant factors among the most vulnerable populations in Ethiopia. METHODS: Electronic databases, including PubMed, Google Scholar, Web of Science, Semantic Scholar, and Scopus were used for searching articles published since the 2020 Gregorian calendar and onwards. All peer-reviewed Ethiopian journals, health institutions, and Universities were considered for article searching. A PRISMA flow chart and Endnote software were used for article screening, and to remove duplications, respectively. The modified version of the Newcastle-Ottawa Scale was used for potential risk of bias assessments. The heterogeneity among the included studies was evaluated using the indicator of heterogeneity (I2). Egger's test and funnel plot were used to examine the possible publication bias. A random-effects analysis was used to assess the pooled prevalence of malaria, and its determinant factors with a 95% CI. The screening process, data extraction, and quality assessment were done independently, and any disagreements were resolved through discussions. RESULTS: A total of twelve studies were included in this study. The pooled malaria prevalence was 11.10% (95% CI: 6.10, 16.11). Stagnant water (AOR: 4.19, 95% CI: 2.47, 7.11), no insecticide-treated net utilization (AOR: 3.15, 95% CI: 1.73, 5.73), and staying outdoors at night (AOR: 5.19, 95% CI: 2.08, 12.94) were the pooled estimated statistically risk factors for malaria prevalence. Whereas, insecticide-treated bed net utilization (AOR: 1.59, 95% CI: 0.23, 10.95) reduces the risk of malaria infection. CONCLUSIONS: The pooled prevalence of malaria is high among vulnerable populations. Creating awareness regarding utilization of insecticide-treated bed nets, and draining stagnant water from the environment are possible interventions to reduce the prevalence of malaria.

BACKGROUND: Although infant deaths worldwide have reduced, many children die before their first birthday. Infant deaths are widespread in low-income countries, and information about the cause of death is limited. In Ethiopia, 53% of infants' deaths occurred in their neonatal period, and 174 infants' deaths occurred from 3684 births. Hence, this study aimed to assess mothers' experiences with infant death and its predictors in Ethiopia. METHODS: A total of 1730 weighted samples of mothers from the 2019 EDHS dataset, which was collected across the regions of Ethiopia, were included for analysis. A two-stage cluster sampling technique with a cross-sectional study design was used. All mothers whose children were under the age of 0-12 months were included in this study. Six count regression models were considered and compared using Akaike's information criteria and Bayesian information criterion with STATA version 15 software. The strength of the association between the number of infant deaths and possible predictors was determined at a P-value less than 0.05, with a 95% confidence interval. The findings were interpreted by using the incident rate ratio. RESULTS: A total of 46.3% of mothers had lost at least one infant by death in the last five years before the 2019 EDHS survey was held. The mean and variance of infant deaths were 2.55 and 5.58, respectively. The histogram was extremely picked at the beginning, indicating that a large number of mothers did not lose their infants by death, and that shows the data had positive skewness. Mothers under 25-29 years of age (IRR: 1.75, 95% CI:1.48, 2.24), and 30-34 years of age (IRR: 1.42, 95% CI: 1.12, 2.82), Somali (IRR: 1.47, 95% CI: 1.02, 3.57), Gambela (IRR: 1.33, 95% CI: 1.10, 2.61), and Harari (IRR: 1.39, 95% CI: 1.02, 2.63) regions, rural resident mothers (IRR: 1.68, 95% CI: 1.09, 1.91, and Protestant (IRR = 1.43, 95% CI: 1.14, 2.96), and Muslim (IRR = 1.59, 95% CI: 1.07, 2.62) religion fellow of mothers were associated with a high risk of infants' deaths. Whereas, being rich IRR: 0.37, 95% CI: .27, .81) and adequate ANC visits (IRR: 0.28, 95% CI: .25, .83) were associated with a low risk of infant death. CONCLUSION: Many mothers have experienced infant deaths, and the majority of infants' deaths occur after the first month of birth. Encouraging mothers to attend antenatal care visits, creating mothers' awareness about childcare, and ensuring equal health services distribution and utilization to rural residents are essential to minimize infant death. Educating lower-aged reproductive mothers would be a necessary intervention to prevent and control infant deaths.

Maternal and child deaths occur during pregnancy and delivery. Timely information on signs of pregnancy complications and ways to plan for normal birth is a strategy to reduce maternal and child deaths. The purpose of this study was to assess birth preparedness, and pregnancy complications readiness and identify associated factors in Ethiopia. A cross-sectional study design was used. A total of 1635 weighted samples of pregnant women were included for analysis from the 2016 Ethiopian demographic and health survey data set. Multilevel mixed-effect logistic regression was used to estimate the effects of potential variables on birth preparedness and complication readiness. STATA version 15 software was used for data processing and analysis. A variable with a p-value < 0.05 with a 95% confidence interval was considered a significant factor. Pregnant women were informed about convulsions (8.02%), fever (35.95%), abdominal pain (28.92%), leaking fluid from the vagina (28.21%), and blurred vision (17.98%). Pregnant women prepared for supplies needed for birth (38.70%), transportation (20.04%), money (18.97%), people's support for birth (5.03%), and blood donors (3.11%). Only 56% and 44.91% of pregnant women had good birth preparedness and were informed about pregnancy complications respectively. Educational status, antenatal care visits, and region were significant factors associated with birth preparedness and complication readiness. Distance to health facility and residency were significantly associated with birth and complication readiness, respectively. Birth preparedness and complication readiness among pregnant women were low in Ethiopia. Empowering women with education, installing safe roads, building accessible health facilities, and emphasizing pregnancy complications and birth preparedness plans during antenatal care visits are important interventions to enhance birth preparedness and pregnancy complication readiness.
RESUMO
BACKGROUND: Digital literacy refers to the capacity to critically assess digital content, use digital tools in professional settings, and operate digital devices with proficiency. The healthcare sector has rapidly digitized in the last few decades. This systematic review and meta-analysis aimed to assess the digital literacy level of health professionals in the Ethiopian health sector and identify associated factors. The study reviewed relevant literature and analyzed the data to provide a comprehensive understanding of the current state of digital literacy among health professionals in Ethiopia. METHODS: The study was examined by using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. Evidence was gathered from the databases of Google Scholar, Pub Med, Cochrane Library, Hinari, CINAHL, and Global Health. Consequently, five articles met the eligible criteria for inclusion. The analysis was carried out using STATA version 11. The heterogeneity was evaluated using the I2 test, while the funnel plot and Egger's regression test statistic were used to examine for potential publication bias. The pooled effect size of each trial is evaluated using a random effect model meta-analysis, which provides a 95% confidence interval. RESULT: A total of five articles were included in this meta-analysis and the overall pooled prevalence of this study was 49.85% (95% CI: 37.22-62.47). six variables, Monthly incomes AOR = 3.89 (95% CI: 1.03-14.66), computer literacy 2.93 (95% CI: 1.27-6.74), perceived usefulness 1.68 (95% CI: 1.59-4.52), educational status 2.56 (95% CI: 1.59-4.13), attitude 2.23 (95% CI: 1.49-3.35), perceived ease of use 2.22 (95% CI: 1.52-3.23) were significantly associated with the outcome variable. CONCLUSION: The findings of the study revealed that the overall digital literacy level among health professionals in Ethiopia was relatively low. The study highlights the importance of addressing the digital literacy gap among health professionals in Ethiopia. It suggests the need for targeted interventions, such as increasing monthly incomes, giving computer training, creating a positive attitude, and educational initiatives, to enhance digital literacy skills among health professionals. By improving digital literacy, health professionals can effectively utilize digital technologies and contribute to the advancement of healthcare services in Ethiopia.

The human papillomavirus is known to cause cervical and anogenital cancer and benign anogenital and cutaneous warts. Both males and females can contract the virus during sexual intercourse and skin-to-skin contact. Communities in low- and middle-income countries, including Africa, are particularly suffering from human papillomavirus-related diseases, mainly cervical cancer. Vaccination is the most economical and efficient prevention strategy to control human papillomavirus-related diseases. Undoubtedly, to control all types of human papillomavirus-related morbidity and mortality, the entire at-risk, sexually active population needs to be vaccinated regardless of their sex. However, the vaccination program, particularly in Africa, the world's most resource-limited region, is habitually limited to the female population, considering only the burden of cervical cancer. We think that it is impossible to fully mitigate the human papillomavirus infection by vaccinating only the female population, while males can carry and pass the virus. In addition, marginalizing males from this program seems to violate gender inequality and their sexual and reproductive health rights. Hence, we voice the need for global and local governments to consider and customize human papillomavirus vaccination programs for the male population. Also, it is better to consider the male population in different research studies regarding human papillomavirus-related malignant and benign conditions.
RESUMO
Background: Inadequate diet among adolescent girls leads to anatomical and physiological disturbances which will contribute to the vicious intergenerational cycle of malnutrition. However, only a few studies are available in Ethiopia on dietary diversity among adolescent girls who are attending school. Objective: The objective of this study is to assess factors associated with inadequate dietary diversity among high school adolescent girls in Hurumu Woreda, Southwest Ethiopia, 2022. Methods: An institution-based cross-sectional study was conducted among 374 high school adolescent girls from 3 May 2022 to 12 June 2022 and selected by using simple random sampling techniques. Data were collected through face-to-face interviews using structured questionnaires. Epi-data version 4.6.0 was used to enter the data, which were then exported to SPSS version 26 for analysis. Simple binary and multivariable logistic regressions were performed to identify factors associated with inadequate dietary diversity. Results: In this study, the magnitude of inadequate dietary diversity among adolescent girls was 62.6% [95% CI: 57.5-66.5]. Living with more than five family members (AOR = 1.8, 95% CI: 1.16-3.44), consumption of sweet foods/beverages (AOR = 2.2, 95% CI: 1.07-3.41), poor nutritional knowledge (AOR = 2.5, 95% CI: 1.48-3.89), and poor household wealth tercile (AOR = 2.8, 95% CI: 1.44-5.12) were significantly associated with inadequate dietary diversity. Conclusion: Living with more than five family members, poor household wealth status, consumption of sweet foods/beverages, family size, and poor nutritional knowledge were factors significantly associated with inadequate dietary diversity. Hence, nutrition education, the use of family planning methods, and securing income-generating activities should be implemented.
RESUMO
Background: Podocarpus gracilis is an evergreen, dioecious tree found in Ethiopia and other African nations. It can reach a height of 60 meters. Without any scientific validation, ethnobotanical studies conducted in Ethiopia revealed that the Podocarpus gracilis plant's leaf is consumed orally to treat diabetes mellitus. Hence, this study aims to evaluate the in vivo blood glucose level lowering, lipid-lowering, and in vitro-free radical scavenging responses of Podocarpus gracilis leaf extract and fractions on experimental mice induced with diabetes. Methods: The in vitro antioxidant activity of PGC (Podocarpus gracilis) leaf extract was assessed by using a diphenyl-2-picrylhydrazyl (DPPH) assay. The oral glucose-loaded, normoglycemic, and streptozotocin- (STZ-) induced diabetic mouse models were employed. In the STZ-induced mice model, the leaf extract and solvent fractions activity on serum lipid and weight were also measured. The extract and fractions were tested at 100, 200, and 400 mg/kg dosages. One-way ANOVA was used to determine the statistical significance of BGL (blood glucose level) changes within and between groups, and Tukey's post hoc multiple comparisons were then performed. Results: In the acute toxicity study of Podocarpus gracilis leaf extract and fractions, there was no evidence of animal mortality at the maximum dose of 2 g/kg during the observation period. The extract-treated group with normoglycemia revealed a significant lowering in BGL at the 4-hour mark of 27.4% (p < 0.001) and 25.2% (p < 0.01) at doses of 200 mg/kg and 400 mg/kg, respectively, compared to that in negative control. In the oral glucose tolerance test (OGTT) model, only 400 mg/kg treated groups at 120 min after exposure showed a BGL reduction of 31.17% which was statistically significant (p < 0.05) in comparison to the negative control. In the single-dose STZ-induced model, eighth-hour BGL measurements from CE 100, CE 200, CE 400, and GLC5 showed drops in BGL of 43.1%, 44.1%, 45%, and 47.3% from baseline fasting BGL values. In the repeated streptozotocin (STZ)-induced model, at all doses of leaf extract and fractions, the fasting BGL was significantly (p < 0.001) reduced. Moreover, the leaf extract and solvent fractions have shown a significant (p < 0.001) reduction of serum lipids such as LDL, TC, and VLDL, and at the same time, it increases HDL at 14 days with body weight gained. In the test for antioxidant activity, the half-maximal inhibitory concentrations (IC50) for leaf extract and the standard medication (ascorbic acid) were 8.2 µg/ml and 3.3 µg/ml, respectively. The IC50 value denotes the concentration of the sample required to scavenge 50% DPPH radicals. Conclusion: The 80% hydromethanolic leaf extract and fractions of Podocarpus gracilis exhibited blood glucose lowering, lipid-lowering activity in normoglycemic, oral glucose tolerance test (OGTT) mode, and STZ-induced diabetic mice with weight gains. There is scientific support for the alleged traditional use as an antidiabetic, lipid-lowering, and antioxidant activity. The results need to be confirmed by future studies.
RESUMO
INTRODUCTION: Childhood vaccination is a cost-effective public health intervention to reduce child mortality and morbidity. But, vaccination coverage remains low, and previous similar studies have not focused on machine learning algorithms to predict childhood vaccination. Therefore, knowledge extraction, association rule formulation, and discovering insights from hidden patterns in vaccination data are limited. Therefore, this study aimed to predict childhood vaccination among children aged 12-23 months using the best machine learning algorithm. METHODS: A cross-sectional study design with a two-stage sampling technique was used. A total of 1617 samples of living children aged 12-23 months were used from the 2016 Ethiopian Demographic and Health Survey dataset. The data was pre-processed, and 70% and 30% of the observations were used for training, and evaluating the model, respectively. Eight machine learning algorithms were included for consideration of model building and comparison. All the included algorithms were evaluated using confusion matrix elements. The synthetic minority oversampling technique was used for imbalanced data management. Informational gain value was used to select important attributes to predict childhood vaccination. The If/ then logical association was used to generate rules based on relationships among attributes, and Weka version 3.8.6 software was used to perform all the prediction analyses. RESULTS: PART was the first best machine learning algorithm to predict childhood vaccination with 95.53% accuracy. J48, multilayer perceptron, and random forest models were the consecutively best machine learning algorithms to predict childhood vaccination with 89.24%, 87.20%, and 82.37% accuracy, respectively. ANC visits, institutional delivery, health facility visits, higher education, and being rich were the top five attributes to predict childhood vaccination. A total of seven rules were generated that could jointly determine the magnitude of childhood vaccination. Of these, if wealth status = 3 (Rich), adequate ANC visits = 1 (yes), and residency = 2 (Urban), then the probability of childhood vaccination would be 86.73%. CONCLUSIONS: The PART, J48, multilayer perceptron, and random forest algorithms were important algorithms for predicting childhood vaccination. The findings would provide insight into childhood vaccination and serve as a framework for further studies. Strengthening mothers' ANC visits, institutional delivery, improving maternal education, and creating income opportunities for mothers could be important interventions to enhance childhood vaccination.

Urinary tract infection (UTI) is one of the most common bacterial infections in women; about 50% of women get during their life time. Moreover, it is a common health problem in patients with gynecological pathologies, which increases the chance of acquiring infection. The aim of this study was to determine the bacterial profile that causes UTI and their antibiotic susceptibility pattern among admitted gynecological cases. A cross-sectional study was conducted in south west Ethiopia region. A total of 386 patients admitted with gynecological cases were recruited by sequential sampling technique and structured questionnaire was used to collect socio-demographic and risk factor-related data. About 10 ml freshly voided midstream and catheterized urine specimens were collected using sterile containers. Identification of isolate was done using culture characteristics, gram staining, and a series of biochemical tests. The antibiotic susceptibility test was performed as per the Kirby-Bauer disc diffusion technique. The data obtained were entered into EpiData Version 3.1 and analyzed using SPSS Version 25. A P value of less than 0.05 was used as a level of significance. In this study, the overall prevalence of UTI was 25.4%. Escherichia coli was the most frequently isolated bacteria, which accounted for 38 (37.6%), followed by Klebsiella species 22 (21.8%), CONS 14 (13.9%), Staphylococcus aureus 10 (9.9%), Enterobacter species 6 (5.9%), Citrobacter species 5 (4.9%), Proteus mirabilis 4 (4%), and Pseudomonas aeroginosa 2(2%). Histories of UTI (AOR = 1.977, 95% CI 1.06, 3.68, P = 0.032) and catheterization (AOR = 2.38, 95% CI 1.28, 4.45, P = 0.006) were found to be statistically associated with significant bacteriuria. Gram-negative isolates showed a high level of resistance, 88.3% for ampicillin and 66.2% for tetracycline, and a relatively low level of resistance against ceftazidime, 22.1%, and meropenem, 3.9%. Gram-positive uropathogens showed a high level of resistance to penicillin, 91.6%, whereas all isolates were sensitive 100.0% to nitrofurantoin. Furthermore, 80 (79.2%) of the isolates had multidrug resistance, and 16 (26.7%) of both E. coli and Klebsiella spp. produced Extended spectrum ß-lactamase (ESBL). In this study, a high prevalence of uropathogenic bacteria and multidrug resistance for commonly prescribed drugs were observed with a significant number of ESBL producers. Therefore, screening admitted gynecological patients, especially for those who have history of catheterization and UTI, by urine culture and antimicrobial susceptibility testing is important.

Background: Nowadays, coronavirus disease is a leading cause of death. Therefore, the study aimed to assess the time to recovery and its predictors among Covid-19 positive patients. Methods: A hospital-based retrospective cohort study was conducted among 300 COVID-19 patients admitted to Southwestern Ethiopian hospital COVID-19 treatment centers from August 7, 2020 to February 7, 2022. Kaplan Meier was used to estimate the survival time and the Log-rank test was used to compare the survival time between groups of categorical variables. The multivariable survival regression model was used to identify a significant predictor of time to recovery among COVID-19 patients at a P value ⩽ 0.05 with a 95% CI. Result: In this study, 92% of patients admitted to Jimma University COVID-19 treatment center and Mettu Karl Comprehensive Specialized Hospital COVID-19 treatment center were recovered from COVID-19 after a maximum of 33 days of follow-up. The overall incidence density was 11.99/100 PD (person day) with a 95% CI of [11.273, 12.719] per 100 PD after a total of 3452 PD observations. The median time of recovery from COVID-19 was 10 days. Age (AHR = 1.945, 95% CI: 1.157, 3.268), hypertension (AHR = 1.856, 95% CI, 1.30, 2.63), diabetes (AHR = 1.406, 95% CI, 1.05, 1.84), being critical (0.298, 2039, 0.434), cancer (AHR = 3.050, 95% CI, 1.172, 7.943), and tuberculosis (AHR = 2.487, 95% CI, 1.504, 4.110) were found to be independent predictors of time to recovery of COVID-19 patients. Conclusion: A total of 92% of patients were recovered within 10 days of the median time. Age, hypertension, diabetes mellitus, tuberculosis, severity of the case, cancer, and the presence of acute kidney injury were predictors of recovery time of COVID-19 patients. Therefore, healthcare providers should give strict follow-up and priority to elderly patients with chronic illnesses and those under supportive care.
RESUMO
Schistosomiasis is a neglected tropical disease that disproportionately affects the poorest people in tropical and subtropical countries. It is a major parasitic disease causing considerable morbidity in Ethiopia. Despite significant control efforts, schistosomiasis transmission is still widespread in many rural areas of the country. The aim of this study was to determine the prevalence and intensity of intestinal schistosomiasis among schoolchildren, as well as to identify schistosomiasis transmission sites in Gomma District, southwestern Ethiopia. Between October 2018 and September 2019, cross-sectional parasitological and malacological surveys were conducted in the study area. The study comprised 492 school-children aged 6 to 15 years old from four primary schools in Gomma District. To identify and quantify eggs of Schistosoma mansoni from the children, stool specimens were collected and processed using double Kato-Katz thick smears. Water bodies adjacent to human settlements in the study area were surveyed for snail intermediate hosts of S. mansoni. Morphological identification of collected snails was conducted, followed by examining their infection status using a dissecting microscope. The overall prevalence of S. mansoni infection was 73.8% (95%CI: 69.9-77.7%) and 41.6% of them had moderate-to-heavy infections. The prevalence of S. mansoni infection differed considerably by age group, with the older age groups (12-15) having a higher prevalence than the younger age groups (6-11) (p < 0.001). The prevalence of infection also varied significantly among schools; Dedo Ureche had the highest prevalence (86.9%) (p = 0.034), while Goga Kilole had relatively the lowest prevalence of S. mansoni infection (59.6%) (p = 0.003). A total of 1463 Biomphalaria pfeifferi snails were collected from 11 survey sites throughout the study area, with 357 (24.4%) of the snails shedding schistosomes cercariae. Despite intensified efforts to scale up mass drug administration in Ethiopia, this study reported high levels of S. mansoni infection among schoolchildren and snail intermediate hosts in rural communities in Gomma. Such a high infection rate warrants pressing needs for targeted and integrated interventions to control the disease in the area.

Soil-transmitted helminthiasis (STHs) and undernutrition are common health problems in developing countries. Several reports showed that STH and undernutrition are often associated. The main aim of this study was to determine the association of STH and undernutrition among schoolchildren in Mettu town, Southwest Ethiopia. A cross-sectional study design was employed. To collect socio-demographic data, semi-structured questionnaire and physical observation were used. Kato-Katz technique and Anthropometric measurements were also considered to see STH infection and determine the nutritional statuses of the study participants respectively. Then, the data generated from the study was managed using Chi-square test and logistic regression analysis to determine the association of demographic variables with infections of helminthes and assess the risk factors for nutritional status of the study participants respectively. As a result, among the 392 study schoolchildren, 331 (84.4%) children were positive for different species of STH and undernutrition accounted 32.6%. Ascaris lumbricoides (39.0%), Trichuris trichiura (32.9%) and hookworm (28.1%) are the predominant STH identified from the study participants. Age, maternal educational and occupation status, and fingernail status of children were found significantly associated (p < 0.05) with the risk of getting STH. Bivariate logistic regression analysis showed that, age (AOR 2.18, 95% CI 1.53, 6.59), maternal illiteracy (AOR 0.13, 95% CI 0.91, 0.34) and maternal occupation (AOR 1.67, 95% CI 1.08, 5.91) were major co-founding factors for the prevalence of STH among study participants. In addition, children with T. trichiura infection were more likely (P < 0.01) to suffer from undernutrition (AOR 0.52, 95% CI 0.31, 0.83). Thus, the findings revealed the high prevalence of STH and it has significant association with undernutrition among school age children in the study area. Anti-helminthic mass drug administration and maternal health education should be anticipated to curve the tragedy.

In Ethiopia, human schistosomiasis is caused by two species of schistosome, Schistosoma mansoni and S. haematobium, with the former being dominant in the country, causing infections of more than 5 million people and more than 37 million at risk of infection. What is more, new transmission foci for S. mansoni have been reported over the past years in the country, raising concerns over the potential impacts of environmental changes (e.g., climate change) on the disease spread. Knowledge on the distribution of schistosomiasis endemic areas and associated drivers is much needed for surveillance and control programs in the country. Here we report a study that aims to examine environmental determinants underlying the distribution and suitability of S. mansoni endemic areas at the national scale of Ethiopia. The study identified that, among five physical environmental factors examined, soil property, elevation, and climatic factors (e.g., precipitation and temperature) are key factors associated with the distribution of S. mansoni endemic areas. The model predicted that the suitable areas for schistosomiasis transmission are largely distributed in northern, central, and western parts of the country, suggesting a potentially wide distribution of S. mansoni endemic areas. The findings of this study are potentially instrumental to inform public health surveillance, intervention, and future research on schistosomiasis in Ethiopia. The modeling approaches employed in this study may be extended to other schistosomiasis endemic regions and to other vector-borne diseases.
RESUMO
BACKGROUND: The prevalence of diabetes mellitus (DM) is increasing globally and its comorbidity with tuberculosis (TB) is re-emerging, especially in low- and middle-income countries. OBJECTIVE: The main aim of this study is to determine the prevalence of DM and HIV infection and their associated risk factors among active tuberculosis patients in Northwest Ethiopia. METHODS: This hospital-based cross-sectional study was conducted between February 1st and June 30th, 2017 among active TB patients in two hospitals of Northwest Ethiopia. Two hundred and sixty-seven active TB cases aged 18 years or older were screened for diabetes using fasting blood glucose (FBG) test. Semi-structured questionnaires were used to collect demographic data, lifestyle habits and clinical data. Identification of pre-diabetes or diabetes in TB patients was achieved according to American Diabetes Association guidelines (2016). RESULTS: Prevalence of DM and TB comorbidity was 11.5% (95% confidence interval, CI 7.8-15.2) compared to 24.9% (95% CI 20.1-30.1) for pre-diabetes. Prevalence of HIV/TB co-infection was 21.9% (95% CI 16.7-26.8). Risk of DM was higher in TB patients from a rural location (adjusted odds ratio, aOR 3.13, 95% CI 1.02-9.62, p = 0.046). Similarly, DM was higher in TB patients who have a family history of DM (aOR 4.54, 95% CI 1.31-15.68, p = 0.017). Furthermore, HIV/TB co-infection was identified as a predictor of DM comorbidity in active TB patients (aOR 5.11, 95% CI 2.01-12.98, p = 0.001). CONCLUSION: The magnitude of DM and pre-diabetes in active TB patients in Northwest Ethiopia was high, warranting collaborative efforts to improve screening and adopt better clinical management strategies for DM-TB comorbid patients. Furthermore, being rural residents, family history of DM and HIV/TB co-infection were found to associate with DM among TB patients, highlighting the importance of the above-mentioned risk factors in the clinical management of this comorbidity.
RESUMO
BACKGROUND: In Ethiopia, schistosomiasis is caused by Schistosoma mansoni and S. haematobium with the former being widespread and more than 4 million people are estimated to be infected by S. mansoni annually with 35 million at risk of infection. Although many school- and community-based epidemiological surveys were conducted over the past decades, the national distribution of schistosomiasis endemic areas and associated socio-environmental determinants remain less well understood. In this paper, we review S. mansoni prevalence of infections and describe key biogeographical characteristics in the endemic areas in Ethiopia. METHODS: We developed a database of S. mansoni infection surveys in Ethiopia through a systematic review by searching articles published between 1975 and 2019 on electronic online databases including PubMed, ScienceDirect, and Web of Science. A total of 62 studies involving 95 survey locations were included in the analysis. We estimated adjusted prevalence of infection from each survey by considering sensitivity and specificity of diagnostic tests using Bayesian approach. All survey locations were georeferenced and associated environmental and geographical characteristics (e.g. elevation, normalized difference vegetation index, soil properties, wealth index, and climatic data) were described using descriptive statistics and meta-analysis. RESULTS: The results showed that the surveys exhibited a wide range of adjusted prevalence of infections from 0.5% to 99.5%, and 36.8% of the survey sites had adjusted prevalence of infection higher than 50%. S. mansoni endemic areas were distributed in six regional states with the majority of surveys being in Amhara and Oromia. Endemic sites were found at altitudes from 847.6 to 3141.8 m above sea level, annual mean temperatures between 17.9 and 29.8 â, annual cumulative precipitation between 1400 and 1898 mm, normalized difference vegetation index between 0.03 and 0.8, wealth index score between -68 857 and 179 756; and sand, silt, and clay fraction in soil between 19.1-47.2, 23.0-36.7, and 20.0-52.8 g/100 g, respectively. CONCLUSIONS: The distribution of S. mansoni endemic areas and prevalence of infections exhibit remarked environmental and ecological heterogeneities. Future research is needed to understand how much these heterogeneities drive the parasite distribution and transmission in the region.

BACKGROUND: Schistosomiasis and fascioliasis are digenean parasitic infections and are among the neglected tropical diseases that have both medical and veterinary importance. They are found mainly in areas having limited access to safe water supply and improved sanitation. METHODS: A cross-sectional study was conducted to determine the prevalence of Schistosoma mansoni and Fasciola species infections and to identify associated risk factors among school children in Amhara Regional State, Ethiopia. Stool specimens were collected from 798 children (419 males, 379 females) and processed using Kato-Katz and formol-ether concentration techniques. A semi-structured questionnaire was used to collect socio-demographic and other exposure information to explore potential risk factors for the infections. RESULTS: The overall prevalence of S. mansoni and Fasciola species infections was 25.6% (95% confidence interval (CI): 22.5-28.6) and 5.5% (95% CI: 3.9-7.1), respectively. S. mansoni was present in all surveyed schools with the prevalence ranging from 12.8% (16/125; 95% CI = 5.6-20.0) to 39.7% (64/161; 95% CI = 32.2-47.2) while Fasciola species was identified in five schools with the prevalence ranging from 2.5% (4/160; 95% CI = 0.001-4.9) to 9.8% (13/133; 95% CI = 4.7-14.8). The prevalence of S. mansoni infection was significantly associated with swimming in rivers (Adjusted odds ratio (AOR): 1.79, 95% CI, 1.22-2.62; P=0.003), bathing in open freshwater bodies (AOR, 2.02; 95% CI, 1.39-2.94; P<0.001) and engaging in irrigation activities (AOR, 1.69; 95% CI, 1.19-2.39; P=0.004), and was higher in children attending Addis Mender (AOR, 2.56; 95% CI, 1.20-5.46; P=0.015 ) and Harbu schools (AOR, 3.53; 95% CI, 1.64-7.59; P=0.001). Fasciola species infection was significantly associated with consumption of raw vegetables (AOR, 2.47; 95% CI, 1.23-4.97; P=0.011) and drinking water from unimproved sources (AOR, 2.28; 95% CI, 1.11-4.70; P=0.026). CONCLUSION: Both intestinal schistosomiasis and human fascioliasis are prevalent in the study area, affecting school children. Behaviors and access to unimproved water and sanitation are among significant risk factors. The findings are instrumental for targeted interventions.
RESUMO
BACKGROUND: Schistosoma mansoni, causing intestinal schistosomiasis, is widely distributed in Ethiopia and new transmission foci are continually reported. Here we report new transmission sites and prevalence of S.mansoni infection among school children in Yachi areas, southwestern Ethiopia. METHODS: A cross-sectional survey was conducted among school children of Yachi Yisa and Yachi Efo elementary schools, southwestern Ethiopia, from April 2017 to June 2017. Three hundred seventeen school children aged six to 15 years were randomly selected to provide stool specimens for helminth infection examination by Kato-Katz and formol-ether concentration techniques. Snail survey was carried out to assess schistosome infection in Biomphalaria pfeifferi. Laboratory bred mice were also exposed to schistosome cercariae shed by B. pfeifferi en masse for definite identification of Schistosoma species. RESULTS: From the 317 stool specimens examined using double Kato-Katz thick smear and single formol-ether concentration techniques, 224 (70.7%) were found positive for at least one intestinal helminth species. The most prevalent parasite was S. mansoni (42.9%) followed by Trichuris trichiura (34.1%) and Ascaris lumbricoides (14.2%). The prevalence of S. mansoni infection was significantly higher among the children attending Yachi Yisa School (49.4%) than those in Yachi Efo School (35.6%) (P = 0.002). The study also revealed that there was a significantly higher prevalence of S.mansoni infection among males (51.2%) than females (33.1%) (P < 0.001). However, the prevalence of S.mansoni infection was not significantly associated with age categories (P = 0.839). B. pfeifferi snails infected with schistosomes were collected from the water bodies found in the study area. After six weeks post exposure, adult S. mansoni worms were harvested from the mesenteric veins of laboratory bred mice. CONCLUSIONS: The study revealed establishment of new S. mansoni transmission foci and moderate prevalence of schistosomiasis in Yachi areas. Hence, treatment of all school-age children once every two years is recommended. Snail control and non-specific control approaches including provision of clean water supply and health education should also complement mass drug administration of praziquantel.

BACKGROUND: There is a paucity of studies that compare efficacy of drugs obtained by different diagnostic methods. METHODS: We compared the efficacy of a single oral dose albendazole (400 mg), measured as egg reduction rate, against soil-transmitted helminth infections in 210 school children (Jimma Town, Ethiopia) using both Kato-Katz thick smear and McMaster egg counting method. RESULTS: Our results indicate that differences in sensitivity and faecal egg counts did not imply a significant difference in egg reduction rate estimates. CONCLUSION: The choice of a diagnostic method to assess drug efficacy should not be based on sensitivity and faecal egg counts only.
