Etiology of bacterial pneumonia and multi-drug resistance pattern among pneumonia suspected patients in Ethiopia: a systematic review and meta-analysis.

BACKGROUND: Bacterial pneumonia can affect all age groups, but people with weakened immune systems, young children, and the elderly are at a higher risk. Streptococcus pneumoniae, Klebsiella pneumoniae, Haemophilus influenzae, and Pseudomonas aeruginosa are the most common causative agents of pneumonia, and they have developed high MDR in recent decades in Ethiopia. This systematic review and meta-analysis aimed to determine the pooled prevalence of bacterial pneumonia and multidrug resistance in Ethiopia. METHODS: The articles were searched extensively in the electronic databases and grey literature using entry terms or phrases. Studies meeting the eligibility criteria were extracted in MS Excel and exported for statistical analysis into STATA version 14 software. The pooled prevalence of bacterial pneumonia and multidrug resistance were calculated using a random-effects model. Heterogeneity was assessed by using the I2 value. Publication bias was assessed using a funnel plot and Egger's test. A sensitivity analysis was done to assess the impact of a single study on the pooled effect size. RESULT: Of the 651 studies identified, 87 were eligible for qualitative analysis, of which 11 were included in the meta-analysis consisting of 1154 isolates. The individual studies reported prevalence of bacterial pneumonia ranging from 6.19 to 46.3%. In this systematic review and metanalysis, the pooled prevalence of bacterial pneumonia in Ethiopia was 37.17% (95% CI 25.72-46.62), with substantial heterogeneity (I2 = 98.4%, p < 0.001) across the studies. The pooled prevalence of multidrug resistance in bacteria isolated from patients with pneumonia in Ethiopia was 67.73% (95% CI: 57.05-78.40). The most commonly isolated bacteria was Klebsiella pneumoniae, with pooled prevalence of 21.97% (95% CI 16.11-27.83), followed by Streptococcus pneumoniae, with pooled prevalence of 17.02% (95% CI 9.19-24.86), respectively. CONCLUSION: The pooled prevalence of bacterial isolates from bacterial pneumonia and their multidrug resistance were high among Ethiopian population. The initial empirical treatment of these patients remains challenging because of the strikingly high prevalence of antimicrobial resistance.

Long noncoding RNAs and circular RNAs as potential diagnostic biomarkers of inflammatory bowel diseases: a systematic review and meta-analysis.

Introduction: Inflammatory bowel disease (IBD) poses a growing global burden, necessitating the discovery of reliable biomarkers for early diagnosis. The clinical significance of dysregulated expression of long noncoding RNAs (lncRNAs) and circular RNAs (circRNAs) in diagnosing IBD has not been well established. Thus, our study aimed to investigate the diagnostic value of lncRNAs and circRNAs for IBD based on currently available studies. Methods: A comprehensive search was carried out in diverse electronic databases, such as PubMed, Embase, Scopus, Science Direct and Wiley Online Library to retrieve articles published until October 30, 2023. Stata 17.0 software was employed to determine pooled sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic ratio (DOR), and area under the curve (AUC). Heterogeneity, subgroup analysis, and meta-regression were explored, and publication bias was assessed using Deeks' funnel plot. Fagan's nomogram and likelihood ratio scattergram were employed to evaluate the clinical validity. Result: A total of 11 articles encompassing 21 studies which involved 1239 IBD patients and 985 healthy controls were investigated. The findings revealed lncRNAs exhibit high level of pooled sensitivity 0.94 (95% CI: 0.87-0.97) and specificity 0.99 (95% CI: 0.89-1.00), along with PLR, NLR, DOR, and AUC values of 64.25 (95% CI: 7.39-558.66), 0.06 (95% CI: 0.03-0.13), 1055.25 (95% CI: 70.61-15770.77), and 0.99 (95% CI: 0.97-0.99), respectively. Conversely, CircRNAs showed moderate accuracy in IBD diagnosis, with sensitivity of 0.68 (95% CI: 0.61-0.73), specificity of 0.73 (95% CI: 0.65-0.79), PLR of 2.47 (95% CI: 1.94-3.16), NLR of 0.45 (95% CI: 0.38-0.53), DOR of 5.54 (95% CI: 3.88-7.93), and AUC value of 0.75 (95% CI: 0.71-0.79). Moreover, findings from subgroup analysis depicted heightened diagnostic efficacy when employing lncRNA H19 and a large sample size (≥100), with notable efficacy in diagnosing both ulcerative colitis (UC) and Crohn's disease (CD). Conclusion: LncRNAs exhibit high diagnostic accuracy in distinguishing patients with IBD from healthy controls signifying their possible use as potential biomarkers, while circRNAs showed moderate diagnostic accuracy. Nevertheless, to validate our findings and confirm the clinical utility of lncRNAs and circRNAs in IBD diagnosis, a large pool of prospective and multi-center studies should be undertaken.

Dyslipidemia among HIV-infected patients in Ethiopia: a systematic review and meta-analysis.

BACKGROUND: Dyslipidemia is responsible for more than half of the global ischemic heart disease (IHD) and more than 4 million deaths annually. Assessing the prevalence of dyslipidemia can be crucial in predicting the future disease development and possible intervention strategies. Therefore, this systematic review and meta-analysis was aimed at assessing the pooled prevalence of dyslipidemia in HIV-infected patients. METHODS: Electronic databases such as EMBASE, Google Scholar, PubMed, Web of Science, ResearchGate, Cochrane Library, and Science Direct were searched for articles and grey literature. All relevant studies found until our search period of May 24, 2023 were included. The Newcastle-Ottawa Quality Assessment Scale was used to assess the quality of the included studies. The data were extracted in Microsoft Excel. The STATA version 14 software was used to conduct the meta-analysis. I2 and Cochran's Q test were employed to assess the presence of heterogeneity between studies. Due to the presence of heterogeneity, a random effect model was used. The publication bias was assessed using the symmetry of the funnel plot and Egger's test statistics. Moreover, subgroup analysis, and sensitivity analysis were also done. RESULTS: A total of nine studies that reported the prevalence of dyslipidemia were included. The overall pooled prevalence of dyslipidemia among HIV-infected patients in Ethiopia was 67.32% (95% CI = 61.68%-72.96%). Furthermore, the overall pooled estimates of dyslipidemia among ART-taking and treatment-naïve HIV-infected patients were 69.74% (95% CI: 63.68-75.8, I2 = 87.2) and 61.46% (95% CI: 45.40-77.52, I2 = 90.3), respectively. Based on lipid profile fractionations, the pooled estimates for high total cholesterol (TC) were 39.08% (95% CI: 31.16-46.99), high triglycerides were 38.73% (95% CI: 28.58-48.88), high low density lipoprotein (LDL-c) was 28.40% (95% CI: 17.24-39.56), and low high density lipoprotein (HDL-c) was 39.42% (95% CI: 30.47-48.38). CONCLUSION: More than two-thirds of HIV-infected patients experienced dyslipidemia. Therefore, it's critical to regularly evaluate lipid alterations in HIV-infected patients in order to prevent the onset of atherosclerosis and other cardiovascular problems.

Antibiogram of uropathogens and associated risk factors among asymptomatic female college students in Dessie town, Northeast Ethiopia.

BACKGROUND: Asymptomatic urinary tract infection (asymptomatic bacteriuria and asymptomatic candiduria) may not be routinely detected in sexually active non-pregnant female population at the initial and reversible stages. This is mainly due to the fact that most women may not feel compelled to seek medical attention. OBJECTIVES: The aim of this study was to determine the prevalence, and factors associated with urinary tract infection (UTI), and antibiogram of the uropathogen isolates among asymptomatic female college students. METHODS: An institutional-based cross-sectional study was conducted at selected colleges in Dessie from January 2021-March 2021. A total of 422 reproductive age (15 to 49 years) non-pregnant female students were included. Socio-demographic and clinical characteristics data were collected using structured questionnaires. Ten mLs of freshly voided mid-stream urine specimen was collected, transported and processed according to the standard operating procedures. Data were coded and entered for statistical analysis using SPSS version 22.0. Descriptive statistics, bivariate and multivariate logistic regression analysis were performed and p-values <0.05 with the corresponding 95% confidence interval (CI) were considered statistically significant. RESULT: The overall prevalence of UTI was 24.6%. The prevalence of asymptomatic UTI bacteriuria and candiduria was 57 (13.5%) and 47 (11.1%), respectively. The predominant uropathogens were Staphylococcus saprophyticus 24 (23.1%), followed by Candida tropicalis 23 (22.1%), Candida albican 10 (9.6%), Candida krusei 9 (8.7%) and Escherichia coli 8 (7.7%). Gram negative bacterial isolates showed a higher level of resistance to amoxicillin-clavulanic acid 24 (92.3%). Gram positive bacterial uropathogens showed high level of resistance to penicillin 28 (96.6%) and trimethoprim-sulfamethoxazole 23 (79.3%). Gram positive bacterial isolates were sensitive to norfloxacin, clindamycin, and ciprofloxacin, accounting for 24 (82.7%), 20 (69.0%), and 19 (65.5%), respectively. Multidrug resistance was seen in 50 (87.7%) of bacterial uropathogens. Factors identified for acquisition of UTI were frequency of sexual intercourse (≥3 per week) (AOR = 7.91, 95% CI: (2.92, 21.42), and genital area washing habit (during defecation (AOR = 5.91, 95%CI: (1.86, 18.81) and every morning (AOR = 6.13, 95%CI: (1.60, 23.45)). CONCLUSION: A significant prevalence of uropathogens, and high resistance of bacterial isolates to the commonly prescribed drugs were detected. Therefore, routine UTI screening, regular health education on the risk of asymptomatic infectious diseases for reproductive age group females, and antimicrobial susceptibility testing should be practiced to avoid the progression of an asymptomatic infection into a symptomatic UTI.

Magnitude and predisposing factors of intestinal parasitosis and tuberculosis coinfection at five health institutions in Southern Ethiopia: A cross-sectional study.

Background and Aims: Intestinal parasites affect the tuberculosis disease outcome by shifting the cell-mediated to humoral immune response and host immune system suppression. However, Mycobacterium tuberculosis (MTB) infection favors the immune escape of parasites. Hence, exploring the rate of intestinal parasitic coinfection with pulmonary tuberculosis (PTB) and its predisposing factors to take better preventive, control, and management measures. Methods: A facility-based cross-sectional study was conducted from September to December 2020 at five health institutions in Hawassa city. A total of 214 PTB patients were diagnosed using the GeneXpert assay and enrolled in this study. Demographic, clinical, and risk factors data were collected using a structured questionnaire. Stool samples were collected using a clean, labeled, and leak-proof stool cup. Stool samples were examined using direct saline microscopy and the formal-ether concentration technique. The data were entered and coded in SPSS software for analysis. Bivariate and multivariate logistic regression were employed to identify the associated risk factors. A p-value less than 0.05 was considered statistically significant. Results: The overall rate of intestinal parasitic-MTB coinfection was 36.9%. The most dominant intestinal parasite was Gardia lamblia (17.8%, 38), followed by Entamoeba histolytica/dispar (9.3%, 20). Intestinal parasitosis coinfection of PTB was associated with being rural resident (adjusted odds ratio [AOR] = 2.42; 95% confidence interval [CI]: 1.23-4.8), not washing of fruits and vegetables before eating [AOR = 4.14; 95% CI: 1.92-9], being at the early stage of anti-TB treatment [AOR = 3; 95% CI: 1.5-6.3] and presence of chronic diseases [AOR = 7; 95% CI: 3.4-14]. Conclusion: The burden of intestinal parasites-MTB coinfection was high. Those who wash fruits and vegetables before eating should be encouraged, early treatment of PTB patients and avoiding the practice of open-field defecation, especially in rural communities, is necessary. The dual effect of coinfection on disease severity and treatment success needs further cohort study.

Clinical profiles, epidemiological characteristics and treatment outcomes of COVID-19 patients in North-eastern Ethiopia: A retrospective cohort study.

BACKGROUND: COVID-19 is a rapidly emerging global health threat and economic disaster. The epidemiology and outcomes of COVID-19 patients in Ethiopia are scarce. Thus, the present study aimed to assess clinical profiles, epidemiological characteristics, and treatment outcomes of patients with COVID-19 and to identify determinants of the disease outcome among COVID-19 patients in North-eastern Ethiopia. METHODS: A retrospective observational cohort study was conducted in North-eastern Ethiopia, from May 2020 to Jan 2022 on a total of 364 SARS-COV-2 infected patients. Demographic and clinical data were abstracted from the medical records of patients. Bivariable and multivariable analyses were conducted to determine the factors associated with the mortality of COVID-19 patients and variables with a P-value < 0.05 were considered statistically significant. RESULT: Among 364 COVID-19 patients included in this study, two-thirds (68.1%) were males with a median age of 34 years. The majority; 42.9% & 33.0% respectively cases were detected at the health facility and community level surveillance. Furthermore, 6.6% of patients had pre-existing comorbidities of which diabetes mellitus (23.1%) and hypertension (15.3%) had the highest frequency. The symptomatic rate of COVID-19 patients was 30.5%. The most common clinical presentations were cough (26.9%), fever (26.1%), and shortness of breath (15.2%). Moreover, the mortality rate of COVID-19 patients was 4.1% which was independently predicted by a history of underlining co-morbidity (AHR:6.09; 95%CI:1.299-28.56; P = 0.022) and a history of severe or critical conditions (AHR 11.8; 95%CI:4.89-28.83; P = 0.003). CONCLUSION: Severe or critical acute COVID-19 and underlining comorbidities are associated with higher mortality. Therefore, critical follow-up and management should be given to patients with underlying diseases is required.

The prevalence of vancomycin-resistant Staphylococcus aureus in Ethiopia: a systematic review and meta-analysis.

INTRODUCTION: Vancomycin-resistant Staphylococcus aureus, identified as a "high priority antibiotic-resistant pathogen" by the World Health Organization, poses a significant threat to human health. This systematic review and meta-analysis aimed to estimate the pooled prevalence of vancomycin-resistant Staphylococcus aureus in Ethiopia. METHODS: This systematic review and meta-analysis was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies that reported VRSA prevalence due to infection or carriage from human clinical specimens were extensively searched in bibliographic databases and grey literatures using entry terms and combination key words. Electronic databases like PubMed, Google Scholar, Wiley Online Library, African Journal Online, Scopus, Science Direct, Embase, and ResearchGate were used to find relevant articles. In addition, the Joanna Briggs Institute quality appraisal tool was used to assess the quality of the included studies. Stata version 14 software was used for statistical analysis. Forest plots using the random-effect model were used to compute the overall pooled prevalence of VRSA and for the subgroup analysis. Heterogeneity was assessed using Cochrane chi-square (I2) statistics. After publication bias was assessed using a funnel plot and Egger's test, trim & fill analysis was carried out. Furthermore, sensitivity analysis was done to assess the impact of a single study on pooled effect size. RESULTS: Of the 735 studies identified, 31 studies that fulfilled the eligibility criteria were included for meta-analysis consisted of 14,966 study participants and 2,348 S. aureus isolates. The overall pooled prevalence of VRSA was 14.52% (95% CI: 11.59, 17.44). Significantly high level of heterogeneity was observed among studies (I2 = 93.0%, p < 0.001). The region-based subgroup analysis depicted highest pooled prevalence of 47.74% (95% CI: 17.79, 77.69) in Sidama region, followed by 14.82% (95% CI: 8.68, 19.88) in Amhara region, while Oromia region had the least pooled prevalence 8.07% (95% CI: 4.09, 12.06). The subgroup analysis based on AST methods depicted a significant variation in pooled prevalence of VRSA (6.3% (95% CI: 3.14, 9.43) for MIC-based methods, and 18.4% (95% CI: 14.03, 22.79) for disk diffusion AST method) which clearly showed that disk diffusion AST method overestimates the pooled VRSA prevalence. The total number of S. aureus isolates was found to be the responsible variable for the existence of heterogeneity among studies (p = 0.033). CONCLUSION: This study showed an alarmingly high pooled prevalence of VRSA necessitating routine screening, appropriate antibiotic usage, and robust infection prevention measures to manage MRSA infections and control the emergence of drug resistance. Furthermore, mainly attributable to the overestimation of VRSA burden while using disk diffusion method, there is an urgent need to improve the methods to determine vancomycin resistance in Ethiopia and incorporate MIC-based VRSA detection methods in routine clinical laboratory tests, and efforts should be directed at improving it nationally.

Burden and seasonal distribution of malaria in Ziquala district, Northeast Ethiopia: a 5-year multi-centre retrospective study.

OBJECTIVE: This study was aimed to determine the 5-year trend of malaria positivity rate in Ziquala district, Northeast Ethiopia. METHODS: Review of blood film reports from health institutions' laboratory record books using predesigned checklists was done as part of an institution-based retrospective study to assess the 5-year (2016/2017-2020/2021) trend of malaria. To display data and analyse patterns in the trend of malaria over the course of years, months and seasons, descriptive statistics were used. The results of the data analysis were displayed in tables and figures using SPSS V.26.0. P values under 0.05 were considered as statistically significant for all comparisons. RESULTS: A total of 46 365 blood films from malaria suspected individuals were diagnosed using microscopy over the last 5 years. Of the diagnosed individuals, 14 429 (31.1%) were confirmed positive for Plasmodium infection. Plasmodium falciparum (59.7%) and Plasmodium vivax (37.0%) were the dominant species. The positivity rate of mixed infection (P. falciparum and P. vivax) was 3.3%. The maximum (3598; 29.6%) and minimum (2085; 29.1%) number of cases were reported in 2019/2020 and 2020/2021, respectively. Of the total cases, 9206 (63.8%) were in males. Moreover, the highest malaria positivity rate was observed in the age group of 15-45 (4040; 28.0%). Among the six health facilities, Ziquala district hospital had the highest malaria positivity rate (35.8%), followed by Tsitsika health centre (27.3%) and Mishra health centre (14.2%). CONCLUSION: With P. falciparum being the most common species, malaria remains a severe public health threat in the district. Therefore, the district health office and other concerned bodies should strengthen and implement evidence-based malaria prevention and control measures.

Trends Analysis of HIV Infection and Antiretroviral Treatment Outcome in Amhara Regional from 2015 to 2021, Northeast Ethiopia.

Background: The persistent efforts of HIV/AIDS epidemiology remain one of the world's most important community health threats. To avoid becoming an epidemic, UNAIDS has set three 90% fast-track targets for 2020, and Ethiopia has also changed its implementation since 2015. However, the achievement targets in the Amhara region have yet to be evaluated at the end of the programme period. Objective: The aim of this study was to assess the Trends of HIV Infection and Antiretroviral Treatment outcome in Eastern Amhara Regional from 2015 to 2021, Northeast Ethiopia. Methods: A retrospective study was conducted by reviewing the District Health Information System from 2015 to 2021. The collected data includes the trend of HIV testing services, the trend of HIV positivity, the yield of HIV testing approaches, the number of HIV positive patients linked to HIV care and treatment or access to lifelong antiretroviral therapy, viral load testing coverage, and viral suppression. A descriptive statistic and trend analysis were computed. Results: A total of 145,639 people accessed antiretroviral therapy. The trend of HIV test positivity has been declining since 2015, peaking at 0.76% in 2015 and declining to 0.60% in 2020. A high level of positivity was reported in volunteer counselling and testing as compared with provider-initiated testing and counselling services. Following an HIV positive, there was an increase in linkage to HIV care and treatment. High suppression rates of viral load indicate testing coverage grew over time. The viral load monitoring coverage was 70% in 2021, with a viral suppression rate of 94%. Conclusion and Recommendations: The trend in achievement in the first 90s was not consistent with predefined goals (90%). On the other hand, there was good achievement in the second and third goals. Hence, intensified case-finding approaches to HIV testing should be strengthened.

Prevalence of Microalbuminuria Among Diabetes Patients in Africa: A Systematic Review and Meta-Analysis.

Background: Microalbuminuria (MAU) is considered the earliest sign of diabetic nephropathy among diabetes patients. In order to effectively manage diabetic nephropathy and its consequences early, detection of microalbuminuria as soon as possible, especially for diabetes patients, is critical. Therefore, the present study aimed to determine the pooled prevalence of microalbuminuria among diabetes patients in Africa. Methods: Electronic databases such as Google Scholar, PubMed, African Journals Online, Web of Science, Cochrane Library, EMBASE, and ResearchGate were searched for articles and grey literature. The STATA version 14 software was used to conduct the meta-analysis. I2 and Cochran's Q test were employed to assess the presence of heterogeneity between studies. Due to the presence of heterogeneity, a random effect model was used. The publication bias was assessed using the symmetry of the funnel plot and Egger's test statistics. Moreover, subgroup analysis, trim and fill analysis, and sensitivity analysis were also done. Results: The overall pooled prevalence of microalbuminuria among diabetes patients in Africa was 37.11% (95% CI 31.27-42.95). Substantial heterogeneity was observed between studies, with I2 values of 94.7%. Moreover, this meta-analysis showed that the pooled estimate of microalbuminuria among type 1 and type 2 diabetes patients was 35.34% (95% CI: 23.89-46.80, I2=94.2), and 40.24% (95% CI: 32.0-48.47, I2=94.9) respectively. MAU, on the other hand, was more common in people with diabetes for more than 5 years 38.73% (95% CI: 29.34-48.13) than in people with diabetes for less than 5 years 31.48% (95% CI: 18.73-44.23). Conclusion: This systematic review and meta-analysis found a high prevalence of microalbuminuria among diabetes patients. As a result, early detection of microalbuminuria is critical for preventing and treating microvascular complications such as diabetic nephropathy and the onset of end-stage renal disease.

Prevalence of hyperuricemia among type 2 diabetes mellitus patients in Africa: a systematic review and meta-analysis.

BACKGROUND: Hyperuricemia increases morbidity and mortality in type 2 diabetic individuals. It is linked to the expansion of diabetes and cardiovascular diseases indicators, as well as being a significant predictor of coronary artery disease. It also leads to a poor prognosis and increment of diabetic complications including diabetic neuropathy, retinopathy, and nephropathy. Therefore, this systematic review and meta-analysis was aimed to determine the pooled prevalence of hyperuricemia among type 2 diabetes mellitus patients in Africa. METHODS: We conducted a systematic review and meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. To identify relevant articles, we searched electronic databases such as PubMed, Google Scholar, African Journal Online, Science Direct, Embase, ResearchGate, Scopus, and Web of Sciences. The quality of the included studies was assessed using the Newcastle-Ottawa Quality Assessment Scale. Statistical analysis was performed using Stata 14.0 software. To evaluate heterogeneity, we utilized Cochran's Q test and I2 statistics. Publication bias was assessed through the examination of a funnel plot and Egger's test. The pooled prevalence was estimated using a random effect model. Furthermore, sub-group and sensitivity analyses were conducted. RESULTS: The overall pooled prevalence of hyperuricemia among type 2 diabetic patients in Africa was 27.28% (95% CI: 23.07, 31.49). The prevalence was highest in Central Africa 33.72% (95% CI: 23.49, 43.95), and lowest in North Africa 24.72% (95% CI: 14.38, 35.07). Regarding sex, the pooled prevalence of hyperuricemia among female and male type 2 diabetic patients was 28.02% (95% CI: 22.92, 33.48) and 28.20% (95% CI: 22.92, 33.48), respectively. CONCLUSION: This systematic review and meta-analysis showed a high prevalence of hyperuricemia among type 2 diabetic patients. So, regular screening and diagnosis of hyperuricemia required for preventing its pathological effects and contribution to chronic complications of diabetes.

Symptomatic and asymptomatic malaria prevalence and its determinant factors in pastoral communities of Waghemira Zone, Northeast Ethiopia: A community-based cross-sectional study.

Background and Aims: Malaria elimination programs have also encountered numerous challenges, such as widespread asymptomatic carriers in endemic areas, which should be taken into account in malaria-control programs for effective transmission interruption. The purpose of this research was to determine the prevalence of symptomatic and asymptomatic malaria infections and associated factors, in pastoral communities. Methods: A community-based cross-sectional study was conducted among selected districts in the Waghemra Zone, Northeast Ethiopia, from September to December 2022. A structured questionnaire was employed to collect sociodemographic data and associated risk factors. Plasmodium species were detected using light microscopy and a rapid diagnostic test. Data entry and analysis were carried out using SPSS version 26 software. The association between dependent and independent variables was explored by using multivariable logistic regression analyses. A statistically significant association was declared at a p-value of <0.05. Results: The overall prevalence of malaria was 21.2% (134/633), with the predominant Plasmodium falciparum infections accounting for 67.8% (87/134). Among asymptomatic participants, 7.5% (34/451) and 10.2% (46/451) were diagnosed by rapid diagnostic test and light microscopy, respectively. On the other hand, the prevalence of symptomatic malaria was 44.5% (81/182) and 48.4% (88/182) as diagnosed by rapid diagnostic test and light microscopy, respectively. The presence of stagnant water near the houses, the utilization of insecticide-treated mosquito nets, the number of insecticide-treated mosquito nets, and outdoor stays at night were all positively linked with the prevalence of malaria. Conclusions: The overall prevalence estimate for symptomatic and asymptomatic malaria was high. Malaria is still a public health problem in the study area. Malaria infection was associated with the presence of stagnant water near the houses, the utilization of insecticide-treated mosquito nets, the number of insecticide-treated mosquito nets, and outdoor stays at night. Improved access to all malaria interventions is needed to interrupt the transmission at the community level.

Global seroprevalence of Toxoplasma gondii infection among patients with mental and neurological disorders: A systematic review and meta-analysis.

Background and Aim: Toxoplasmosis is the most widespread zoonotic disease that affects one-third of the world's population, and imposes a major public health problem worldwide. This study aimed to assess the prevalence of toxoplasmosis among patients with neuropsychiatric patients. Methods: Electronic databases PubMed, Google Scholar, Web of Science, Research Gate, and Scopus were thoroughly searched from February to March 2022 to identify all relevant studies. The quality of studies was evaluated using the Newcastle-Ottawa quality scale for case-control and cross-sectional studies. Statistical analysis was done using STATA version 12 software. A random effect model was used to compute the global pooled seroprevalence of Toxoplasma gondii infection. Heterogeneity was quantified by using I 2 value. Subgroup analysis was done, and publication bias was assessed using a funnel plot and Egger's test. Result: Of 1250 studies, 49 containing 21,093 participants and conducted in 18 countries were included. The global pooled seroprevalence of T. gondii IgG antibody was 38.27% (95% CI: 32.04-44.9) among neuropsychiatric patients and 25.31% (95% CI: 21.53-29.08) in healthy controls with substantial heterogeneity of 98.3%. The prevalence of T. gondii IgG antibody was higher in males (17.52%) than in females (12.35%) neuropsychiatric patients. The highest pooled prevalence of T. gondii IgG antibody was in Europe (57%) followed by Africa (45.25%) and Asia (43%). Time based analysis showed the highest pooled prevalence of T. gondii IgG antibody in 2012-2016 (41.16%).The global pooled seroprevalence T. gondii IgM antibody among neuropsychiatric patients and healthy controls was 6.78% (95% CI: 4.87-8.69) and 3.13% (95% CI: 2.02-4.24), respectively. Conclusion: The pooled prevalence of chronic and acute T. gondii infection among neuropsychiatric patients was 38.27% and 6.78%, respectively. This showed a high burden of toxoplasmosis among neurological and psychiatric patients and urges routine screening of those patients and providing appropriate treatment. It also indicates the need for different stakeholders to develop targeted prevention and control strategies for T. gondii infection.

Hepatitis B and C virus infections and associated factors among HIV-positive and HIV-negative tuberculosis patients in public health facilities, Northeast Ethiopia: A comparative cross-sectional study.

Objective: Viral hepatitis, particularly hepatitis B virus and hepatitis C virus, is the leading cause of global liver-related morbidity and mortality. Concomitant infections of hepatitis B virus, hepatitis C virus, and tuberculosis are risks of hepatotoxicity and death due to antituberculosis therapy. Hepatitis and human immunodeficiency virus coinfection poses challenges in treating hepatotoxic patients and leads to mortality during antituberculosis treatment. Thus, this study aimed to determine the prevalence of hepatitis B virus and hepatitis C virus infections, and associated factors among human immunodeficiency virus-positive and human immunodeficiency virus-negative tuberculosis patients attending public health facilities, Northeast Ethiopia. Methods: A comparative cross-sectional study was conducted among 229 tuberculosis patients from January 1 to April 30, 2021 in public health facilities' tuberculosis treatment centers. Study participants were selected using a consecutive sampling technique. Data on sociodemographic and other risk factors were collected using an interviewer-based pretested questionnaire by trained data collectors. Anti-hepatitis C virus and hepatitis B surface antigen were determined in serum using enzyme-linked immunosorbent assay. Data were entered and analyzed using SPSS version 22. Logistic regression analysis was computed, and then variables with a p value <0.05 were considered as statistically significant. Result: The overall hepatitis virus infection among human immunodeficiency virus-positive and human immunodeficiency virus-negative tuberculosis patients was 14.03% and 8.14%, respectively. The prevalence of hepatitis B virus infection in human immunodeficiency virus positives and human immunodeficiency virus negatives was 10.5% and 6.4% and hepatitis C virus infection in human immunodeficiency virus positives and human immunodeficiency virus negatives was 3.5% and 1.75%, respectively. Hepatitis B virus and hepatitis C virus coinfections were not observed. Older age, history of problematic alcohol use, history of blood transfusion, ear-noise piercing, and history of multiple heterosexual partners were predictors for the hepatitis virus infection. Conclusion: Hepatitis virus infection increases morbidity and mortality of tuberculosis patients. Therefore, screening tuberculosis patients for hepatitis virus infection is necessary to reduce the risk of antituberculosis complications.

Prevalence of carbapenemase-producing Enterobacteriaceae from human clinical samples in Ethiopia: a systematic review and meta-analysis.

INTRODUCTION: Carbapenemase-producing Enterobacteriaceae are by far the most public health and urgent clinical problems with antibiotic resistance. They cause longer hospital stays, more expensive medical care, and greater mortality rates. This systematic review and meta-analysis aimed to indicate the prevalence of carbapenemase-producing Enterobacteriaceae in Ethiopia. METHODS: This systematic review and meta-analysis was conducted based on Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Electronic databases like PubMed, Google Scholar, CINAHL, Wiley Online Library, African Journal Online, Science Direct, Embase, ResearchGate, Scopus, and the Web of Sciences were used to find relevant articles. In addition, the Joanna Briggs Institute quality appraisal tool was used to assess the quality of the included studies. Stata 14.0 was used for statistical analysis. Heterogeneity was assessed by using Cochran's Q test and I2 statistics. In addition, publication bias was assessed using a funnel plot and Egger's test. A random effect model was used to estimate the pooled prevalence. Sub-group and sensitivity analysis were also done. RESULTS: The overall pooled prevalence of carbapenemase-producing Enterobacteriaceae in Ethiopia was 5.44% (95% CI 3.97, 6.92). The prevalence was highest [6.45% (95% CI 3.88, 9.02)] in Central Ethiopia, and lowest [(1.65% (95% CI 0.66, 2.65)] in the Southern Nations and Nationalities People Region. In terms of publication year, 2017-2018 had the highest pooled prevalence [17.44 (95% CI 8.56, 26.32)] and 2015-2016 had the lowest [2.24% (95% CI 0.87, 3.60)]. CONCLUSION: This systematic review and meta-analysis showed a high prevalence of carbapenemase-producing Enterobacteriaceae. So, to alter the routine use of antibiotics, regular drug susceptibility testing, strengthening the infection prevention approach, and additional national surveillance on the profile of carbapenem resistance and their determining genes among Enterobacteriaceae clinical isolates are required.

Superbugs and Bacterial Epidemiology from Wound Infection at Health Institutions in Northeast Ethiopia.

Wound infection plays an important role in the development of chronicity by delaying wound healing, prolonging hospital stay, increasing treatment cost and is responsible for significant morbidity. The aim of this study was to investigate the bacterial epidemiology, multi-drug resistance, and associated risk factors for wound infection at health institutions in Northeast Ethiopia. A facility-based cross-sectional study was conducted from February to April 2021. Demographic, clinical, and risk factor variables were collected using a structured questionnaire. Swabs/pus from wound were collected using sterile applicator swab. Specimens were inoculated on culture media and bacterial isolates were identified using microbiological techniques. Antimicrobial susceptibility test was performed using Kirby-Bauer disc diffusion method. Statistical analysis was done using SPSS software. A total of 229 participants were included in this study. A total of 170 bacterial isolates (74.2%) were isolated. The predominant isolates were S. aureus 80 (47.05%), followed by P. aeruginosa 29 (17.05%), E. coli 22 (12.94%), and Klebsiella spp. 16 (9.41%). Tetracycline (71.7%), clindamycin (15.2%), erythromycin (30.4%), penicillin (80.4%), and co-trimoxazole (80.4%) resistance rates were observed among Gram positive bacterial isolates. The overall prevalence of multi-drug resistance was 71%. Hence, improving the laboratory setup for culture and drug susceptibility testing is recommended for effective treatment of wound infection and to improve infection prevention and control practices in healthcare settings.

Epidemiology and prevention of hospital-acquired carbapenem-resistant Enterobacterales infection in hospitalized patients, Northeast Ethiopia.

Objective: Carbapenemase-producing carbapenem-resistant Enterobacterales (CP-CRE) are usually healthcare associated. The aim of this study was to investigate the epidemiology of hospital-acquired CRE and multi-drug-resistant infections, and identify associated risk factors in hospitalized patients in Northeast Ethiopia. Methods: This cross-sectional study was conducted in patients admitted with sepsis between January and June 2021. Demographic and clinical data were collected using questionnaires. In total, 384 samples were collected and cultured based on source of infection. Bacterial species identification was performed using biochemical tests, and drug susceptibility testing was done using the Kirby-Bauer disk diffusion method. The modified carbapenem inactivation method was employed for carbapenemase detection. Data were analysed using Statistical Package for the Social Sciences. Results: The overall rate of CP-CRE infection was 14.6%. Bloodstream infections and urinary tract infections were the predominant hospital-acquired infections (HAIs). The majority of CP-CRE were Escherichia coli and Klebsiella pneumoniae, and accounted for 4.9%. Chronic underlying disease (adjusted odds ratio (AOR): 7.9, 95% confidence interval (CI): 1.9-31.5), number of beds per room (AOR: 11, 95% CI: 1.7-75) and eating raw vegetables (AOR: 11, 95% CI: 3.4-40) were significantly associated with hospital-acquired CRE infection. Conclusions: The rate of CP-CRE infection found in this study is concerning. There is a need for further evaluation of risk factors and measures to decrease HAI. Hand hygiene, increased laboratory capacity, improved infection prevention measures, and antimicrobial stewardship programmes are needed in healthcare settings to halt the transmission of CP-CRE.

Tuberculosis Treatment Outcomes and Its Predictors among Tuberculosis Patients Registered at Tefera Hailu Memorial General Hospital, Sekota Town, Northeast Ethiopia: A Seven-Year Retrospective Study.

Background: Despite the availability of effective medications, tuberculosis (TB) continues to be a serious global public health problem, primarily affecting low and middle-income nations. Measuring and reporting TB treatment outcomes and identifying associated factors are fundamental parts of TB treatment. The goal of this study was to look at the outcomes of TB treatment and the factors that influence them in Sekota, Northeast Ethiopia. Materials and Methods: A facility-based retrospective study was conducted in Tefera Hailu Memorial General Hospital, Sekota town, Northeast Ethiopia. All TB patients who registered in the TB log book and had known treatment outcomes at the treatment center between January 1, 2015, and December 30, 2021, were included in this study. The data was gathered utilizing a pretested structured data extraction format that comprised demographic, clinical, and treatment outcome characteristics. Data were entered, cleaned, and analyzed using SPSS version 25. Descriptive statistics and logistic regression analysis were employed. A p value of less than 0.05 was considered statistically significant. Results: A total of 552 registered TB patients' data were reviewed. Of these, 49.6% were male, 94.4% were new cases, 64.9% were presented with pulmonary TB, and 18.3% were HIV positive. Regarding the treatment outcome, 11.6% were cured, 82.2% completed their treatment, 1.1% had failed treatment, 1.3% were lost to follow-up, and the remaining 3.8% died during the follow-up. The overall treatment success rate among TB patients was 93.8%. The maximum number of successful treatment outcomes was 94.9% in 2021, while the lowest was 86.7% in 2020. The pattern of successful treatment results changes with the number of years of treatment. In the current study, being a new TB patient (AOR = 1.75, 95% CI: 1.31-7.32) and being an HIV-negative patient (AOR = 2.64, 95% CI: 1.20-5.8) were factors independently associated with a successful treatment outcome. Conclusion: The rate of successful TB treatment outcomes in the current study was satisfactory. This achievement should be maintained and enhanced further by developing effective monitoring systems and educating patients about medication adherence.

Prevalence and Determinant Factors of Intestinal Parasitic Infections and Undernutrition among Primary School Children in North-Central Ethiopia: A School-Based Cross-Sectional Study.

Background: Intestinal parasitic infections (IPIs) are a major public health problem with high morbidity and mortality in developing countries. Undernutrition is a major health problem among school children and affects their cognitive development, psychological development, motor skills, and academic achievements. Therefore, this study aimed to assess the prevalence and determinant factors of IPIs and undernutrition among primary school children. Method: Cross-sectional study was conducted among 450 children from February to March 2021 at selected primary schools in Dessie town, North-central Ethiopia. Participants were selected using a stratified sampling technique. Pretested questionnaires were used to collect sociodemographic and nutrition-related data. Stool samples were used to diagnose IPIs. Participants' height and weight were measured and body mass index (BMI) was calculated. Nutritional assessment was done using WHO AnthroPlus software. Data were analyzed using SPSS version 26 software. P-values <0.05 were considered statistically significant. Result: The overall prevalence of intestinal parasites was 28.9%. The prevalence of intestinal protozoa and helminths were 19.1% and 9.8%, respectively. Entamoeba histolytica/dispar was the most prevalent parasite (9.3%) followed by Giardia intestinalis (7.6%), Enterobius vermicularis (2.9%), and Ascaris lumbricoides (2.7%). The prevalence of intestinal parasites was higher in male (16.5%) than in female (12.4%) participants. Children whose mother's level of education is illiterate, 6-11 years old, have a habit of eating raw/undercooked fruits and vegetables, untrimmed and dirty fingernails, and sickness in the past week were significantly associated with IPIs. The prevalence of underweight, stunting, and wasting were 22.4%, 26.2%, and 20.7%, respectively. Multivariable logistic regression showed gender, family size, meal frequency, and breakfast were significantly associated with undernutrition. IPIs had a statistically significant association with underweight, stunting, and wasting. Conclusion: The study showed that IPIs and undernutrition are still major health problems among children in North-central Ethiopia. Periodic deworming, community health, and school health education will be valuable to improve the health, growth, and educational outcome of children.

Asymptomatic Carriage Rate, Multidrug Resistance Level, and Associated Risk Factors of Enterococcus in Clinical Samples among HIV-Positive Patients Attending at Debre Birhan Comprehensive Specialized Hospital, North Showa, Ethiopia.

Background: Enterococci are facultative anaerobic, Gram-positive bacteria found in pairs and short chains that exist as normal microflora both human and animal. Enterococci have become a substantial source of nosocomial infections in immunocompromised patients, such as urinary tract infection (UTI), bacteremia, endocarditis, and wound infection. Earlier antibiotic therapy, length of hospital stays, and length of earlier vancomycin treatment, surgical wards, or intensive care units are all risk factors. Additionally, the presence of coinfections such as diabetes and renal failure and the presence of a urinary catheter were aggravated factors to develop infections. Data on the prevalence, antimicrobial susceptibility patterns, and associated factors of enterococcal infection among HIV-positive patients are scarce in Ethiopia. Objective: To determine the asymptomatic carriage rate, multidrug resistance pattern, and risk factors of enterococci in clinical samples among HIV-positive patients attending at Debre Birhan Comprehensive Specialized Hospital, North Showa, Ethiopia. Methods: A hospital-based cross-sectional study was conducted from May to August 2021, at Debre Birhan Comprehensive Specialized Hospital. To obtain sociodemographic data and possible associated factors of enterococcal infections, a pretested structured questionnaire was utilized. During the study period, clinical samples such as urine, blood, swabs, and other bodily fluids from participants sent to the bacteriology section for cultures were included. The study comprised a total of 384 HIV-positive patients. Enterococci were identified and confirmed using bile esculin azide agar (BEAA), Gram stain, catalase response, growth in broth containing 6.5% NaCl, and growth in BHI broth at 45°C. Data were entered and analyzed using SPSS version 25. P values < 0.05 with 95% confidence interval were considered statistically significant. Result: The overall asymptomatic carriage rate of enterococcal infection was 8.85% (34/384). Urinary tract infections were the most common, followed by wounds and blood. The vast majority of the isolate was found in urine, blood, and wound and fecal, 11 (32.4%), 6 (17.6%), and 5 (14.7%), respectively. Overall, 28 (82.35%) bacterial isolates were resistant to three and more than three antimicrobial agents. Duration of hospital associated with >48-hour hospital stays (AOR = 5.23, 95% C.I: 3.42-24.6), previous history of catheterization (AOR = 3.5, 95% C.I: 5.12-44.31), WHO clinical, stage IV (AOR = 1.65, 95% C.I: 1.23-3.61), andCD4 count < 350(AOR = 3.5, 95% C.I: 5.12-44.31) (P < 0.05). All were associated with higher level of enterococcal infection than their respective groups. Conclusion and Recommendation. Patients with UTIs, sepsis, and wound infection had a greater rate of enterococcal infection than the rest of the patients. Clinical samples in the research area yielded multidrug-resistant enterococci, including VRE. The presence of VRE suggests that multidrug-resistant Gram-positive bacteria have fewer antibiotic treatment options.
