RESUMO
Background: Co-infection of Mycobacterium tuberculosis (MTB) and the Human Immunodeficiency Virus (HIV) is a major global public health issue, particularly in border areas of resource-limited nations, including Ethiopia. Objective: To explore the prevalence and associated variables of MTB/HIV co-infection among PTB presumptive patients in Northwest Ethiopia. Methods: From February to August 2021, a cross-sectional institutional investigation was conducted at the Metema and Abrehajira hospitals. Semi-structured questionnaires were used to collect socio-demographic and clinical data. The MTB/RIF Xpert assay was used to process sputum, and 3 ml of veins blood was collected for HIV rapid test (STAT-PAK, ABON, and SD BIOLINE HIV test algorithm) following the Ethiopian National HIV test algorithm. The Gene Xpert assay's sample processing control was checked to ensure data quality. Data entered into Epi-Data were exported to SPSS version 20 for analysis. Statistically significant variables (p-value ≤0.2) from bivariable analysis were included in multivariable analysis. A p-value ≤ 0.05 was judged statistically significant. Results: This study included 314 PTB presumptive patients with a median age of 35.0 years, of which 178 (56.69 %) were males. Among all patients, 40(12.7 %) and 51(16.2 %) were PTB, and HIV seropositivity, respectively. Of the PTB patients, 14/40 (35 %) (95 % CI: 24.4-45.6) were co-infected with HIV/AIDS. Married patients were 70 % less likely than unmarried individuals (AOR = 0.3 CI; 0.07-0.98) to have MTB/HIV co-infection. Patients who had contact history with MDR-TB patients (AOR = 5 CI; 1.37-18.00), and those who had a history of alcohol use (AOR = 12.2 CI; 2.56-57.8) were more likely to have MTB-HIV co-infection than their peers. Conclusion: Our findings showed that MTB-HIV co-infection is one of the most important community health concerns in the study area. Therefore, MTB/HIV cooperation activities should be fully in place to prevent co-infection and its impact on the population.
RESUMO
BACKGROUND: Globally, hepatitis B virus (HBV) and hepatitis C virus (HCV) cause considerable morbidity and mortality from their acute and chronic infections. The transmission of the viruses within the prisons is high due to overcrowding, and other risk behaviors such as drug use, and unsafe sexual practices. This study aimed at determining the prevalence and associated factors of HBV and HCV infections among prisoners in Gondar city, Northwest Ethiopia. METHODS: A cross-sectional study was conducted in the Gondar City Prison Center from May 1, 2022, to July 30, 2022. A total of 299 prison inmates were selected by using a systematic random sampling technique. A semi-structured questionnaire was used to collect data on sociodemographic, clinical, behavioral and prison related factors. Five milliliters of blood sample were collected, and the serum was separated from the whole blood. The serum was tested for HBV surface antigen (HBsAg) and anti-HCV antibody by using an Enzyme-Linked Immunosorbent Assay (ELISA). Data was entered using EpiData version 4.6.0 and exported to SPSS version 20 for analysis. Logistic regression analysis was done to assess the association between the independent variables and HBV and HCV infections. P-values < 0.05 were considered statistically significant. RESULTS: The overall seroprevalence of HBV or HCV infections was 10.4%. The seroprevalence of HBV and HCV infections was 7.0% and 4.0%, respectively. It has been demonstrated that having several heterosexual partners, sharing sharp materials in prison, having longer imprisonment, and having a body tattoo are significantly associated with HBV infection. The presence of a body tattoo, a history of surgical procedures, and previous imprisonment are associated risk factors for HCV infection. CONCLUSION: The prevalence of HBV and HCV were high-intermediate and high, respectively. Therefore, preventative and control initiatives are needed in prisons to decrease the rate of infection and transmission.

Introduction: Border areas are important sites for disseminating Mycobacterium tuberculosis among individuals living in such areas. This study examined patients with suspected pulmonary tuberculosis (PTB) visiting the Abrihajira and Metema hospitals in northwest Ethiopia to investigate the prevalence of rifampicin-resistant Mycobacterium tuberculosis (RR-MTB), multidrug-resistant Mycobacterium tuberculosis (MDR-MTB), and risk factors related to Mycobacterium tuberculosis infection. Methods: A hospital-based cross-sectional study was conducted from February to August 2021 among 314 PTB presumptive patients. Xpert MTB/RIF and line probe assays (LPA) were used to process sputum samples. Data were imported into the Epi-Data 3.1 program and exported to Statistical Package for the Social Sciences (SPSS) version 20.0 (SPSS, Chicago, IL, United States) to conduct the analysis. A logistic regression analysis was used to investigate the relationship between the dependent and independent variables. A value of p of <0.05 denoted statistical significance. Results: Of the total (314) PTB presumptive patients who participated in this study, 178 (56.69%) were men, and 165 (52.5%) were from 25 to 50 years of age with a median age of 35.00 (inter-quartile: 25-45 years). Among all patients, 12.7% had PTB by Gene Xpert and 7/314 (2.23%) were resistant to rifampicin. Among patients enrolled, 4/314 (1.27%) had MDR-MTB (resistant to RIF and INH) by LPA. Regarding the risk factors assessed, primary level of education, sputum production, night sweating, respiratory disorder, contact history of TB, history of MDR-MTB infection, history of alcohol use, and cigarette smoking showed statistical significance with the prevalence of PTB (p ≤ 0.05). Discussion: This study observed a high prevalence of PTB, RR-MTB, and MDR-MTB compared with many other previous studies conducted in Ethiopia. Among the assessed risk factors that could be associated with the prevalence of PTB, eight were statistically significant. This prevalence, resistance, and statistically significant variables are the evidence to which more emphasis should be given to the country's border areas.
RESUMO
BACKGROUND: Despite the availability of effective vaccines and treatments for hepatitis B virus (HBV), it continues to be a major public health problem in sub-Saharan Africa including Ethiopia. Routine screening for HBV in pregnant women is widely recommended, but there is lack of screening for HBV during pregnancy in Ethiopia. Therefore, this study aimed to assess viral load, and genetic diversity among pregnant women in the Amhara National Regional State, Ethiopia. MATERIALS AND METHODS: Hepatitis B surface antigen (HBsAg) testing was performed on 1846 pregnant women, 85 of who tested positive were included in this study. HBV DNA was isolated from 85 positive sera, and the partial surface/polymerase gene was amplified and sequenced. HBV genotypes, sub-genotypes, serotypes and mutations in surface genes and polymerase were studied. RESULTS: Out of 85 pregnant women`s HBsAg positive sera, 59(69.4%) had detectable viral DNA. The median viral load was 3.4 log IU/ml ranging from 2.6 to7.6 and 46 samples were successfully sequenced and genotyped. Genotypes A and D were identified in 39 (84.8%) and 7 (15.2%); respectively. All genotype A isolates were further classified into sub-genotype A1 and serotype adw2 (84.8%) whereas genotype D isolates were further classified into three sub genotypes; 2 (4.3%) D2, 1(2.2%) D4, and 4 (8.7%) D10 with serotypes ayw2 (10.9%), and ayw3 (4.3%). There were 19 (41.3%) surface gene mutations in the major hydrophilic region (MHR). Six (13.1%) of them were discovered in MHR`s `a'-determinant region. Six polymerase gene mutations (13%) were identified. CONCLUSION: Genotype A was the predominant genotype in the Amhara National Regional State. The surface and polymerase gene mutations identified in this study may lead to immune therapy failure, diagnostics escape and drug resistance. Thus, the data generated in this study will contribute to the planning of HBV diagnosis, vaccination and treatment, and most importantly to the prevention of vertical transmission of HBV in Ethiopia. Therefore, further molecular studies on HBV are warranted and continuous surveillance is important for patient management and for the prevention and control of HBV infection in the country.

BACKGROUND: Hepatitis is an inflammation of the liver and often caused by viruses. Hepatitis viruses are the leading causes of liver-related morbidity and mortality worldwide, with Hepatitis B and C viruses share the great majority. Studies have shown that prison settings are one of the high-risk environments for the transmission of these viruses. However, there is limited information on the seroprevalence and associated factors of hepatitis B and C viral infection among Ethiopian prisoners. METHODS: A facility-based cross-sectional study was conducted among 339 prisoners in Dessie town, Ethiopia from February to April 2020. Hepatitis B surface antigen and antibody against hepatitis C virus in serum were determined using Enzyme-Linked Immunosorbent Assay. We imputed the data using "EpiData 3.1" software and exported it to Statistical Package for Social Sciences version 20.0 for analysis, and a p-value of <0.05 was considered statistically significant. RESULTS: The overall seroprevalence of hepatitis B surface antigen and anti-hepatitis C virus among prisoners was 22/339 (6.5%) (95% CI = 3.8-9.4), and 4/339 (1.2%) (95% CI = 0.0-2.4), respectively. Multiple sexual partners, previous imprisonment, body tattooing, and contact with the jaundiced patient were independently associated with hepatitis B virus infection. Prisoners who had a history of blood transfusion, and dental extraction were independently associated with hepatitis C virus infection. CONCLUSION: The seroprevalence of hepatitis B and hepatitis C viral infection among Dessie town prisoners was intermediate and low, respectively. The finding of a significant association between the presence of Hepatitis B surface antigen and hepatitis C virus antibodies among prisoners and factors calls for the need of serological testing for both Hepatitis B and C viruses to high-risk individuals. Strengthening screening strategies and prevention programs in prison settings is advisable to prevent disease transmission.
RESUMO
Chronic hepatitis B virus infection is a source of substantial global health problems, particularly in economically underdeveloped and/or developing countries. It is the primary cause of severe liver disorders such as liver fibrosis, cirrhosis, and hepatocellular carcinoma. The liver is connected by the bile duct to the small intestine that carries bile produced in the liver to the intestine. The liver is the initial organ exposed to materials originating from the gut including dietary compounds, bacteria, and their products. Human intestines harbor a wide diversity of the community of microbes which are collectively termed as gut microbiota. In chronic infection with the hepatitis B virus, microbial alteration of the gut is a source of systemic immune activation. Besides, gut permeability is altered in hepatitis B virus-infected patients with an increased bacterial translocation and endotoxin load in the portal vein that caused toll-like receptor activation in the liver, which facilitates immune-mediated liver injury. Toll-like receptors further triggered the host-wide inflammatory response by inducing signaling cascades such as nuclear factor-kappa B-linked pathways and by accelerating cytokine secretion like tumor necrosis factor-alpha, which evokes chronic inflammation and leads to liver lesion formation, fibrosis progression, and cirrhosis and hepatocellular carcinoma development. In conclusion, changes in intestinal flora play an important role in encouraging the production of chronic infection with the hepatitis B virus. Therefore, careful attention should be given to the maintenance of intestinal microecology of patients which can provide a sound foundation for the treatment of chronic infection with the hepatitis B virus.
RESUMO
BACKGROUND: Hepatitis C virus is a highly genetically heterogenous bloodborne pathogen that is responsible for acute and chronic hepatitis. Globally, an estimated 71 million population is chronically infected with this virus from which 399,000 people die every year. Its prevalence is high in Ethiopia and varies from region to region, even among different studies within a region. METHODS: Electronic databases, including Science Direct, Medline, HINARI, African Journals Online, TRIP database, African Index Medicus, and Directory of Open Access Journals, searched from 2010 to 2020 and published articles were included. Due to evidence of considerable heterogeneity, the pooled prevalence of anti-HCV was analyzed using the random-effects model. The possible sources of heterogeneity were analyzed through subgroup analysis, sensitivity analysis, and meta-regression. Funnel plots and Egger's test statistics were used to determine the presence of publication bias. RESULTS: The analysis of 56 articles showed that the prevalence of anti-HCV in Ethiopia ranged from 0% to 22%. The pooled prevalence estimated was 2% (95% CI 2.0-3.0), and the meta-regression statistics indicated that the diagnostic method (p=0.037), study group (p=0.005), and level of bias (p=0.035) showed statistically significant association with the outcome variable. The sensitivity analysis claims no influence on the overall effect estimate while removing a single study from the analysis at a time. Egger's test statistics (p ≤ 0.001) declare the presence of publication bias that is handled using time and fill analysis. CONCLUSIONS: The pooled prevalence of anti-HCV in Ethiopia was high. Predictor variables, including the diagnostic method, study group, and level of bias, showed a statistically significant relationship with the outcome variable. Strengthening the scope of existing prevention and control programs and implementing novel approaches, including screen-and-treat, could significantly help to tackle this critical public health issue. The study provides a current estimate which is valuable for policymakers and other responsible bodies.

BACKGROUND: Multidrug resistance (MDR), extended-spectrum beta-lactamase (ESBL) and carbapenemase-producing Gram-negative bacteria (GNB) has become a public health threat worldwide. This threat is worse in developing countries where there is high infectious disease burden and spread of antimicrobial resistance co-exist. The aim of the present study was, therefore, to assess MDR, ESBL and carbapenemase producing GNB from patients attending three selected referral hospitals in Amhara region. METHODS: A cross-sectional study was conducted from December 2017- April 2018 at the University of Gondar Comprehensive Specialized Hospital, Dessie Referral Hospital and Debre Markos Referral Hospital of Amhara national regional state. A total of 833 study subjects were recruited using a convenient sampling technique. Clinical samples such as blood, urine, stool, wound, abscess, ear discharge, nasal discharge, cervical discharge and body fluid specimens were aseptically collected. Culturing for identification of bacteria and determination of drug susceptibility testing were done following standard microbiological techniques. Selected MDR isolates were phenotypically assessed for ESBL and carbapenemase production. RESULTS: Of the 833 clinical samples cultured for bacterial growth, 141 (16.9%) were positive for GNB. The most common GNB identified were E. coli 46 (32.6%), Klebsiella spp. 38 (26.5%) and Proteus spp. 13 (9.2%). The overall MDR prevalence was 121 (85.8%). Among the total isolates, 137 (97.2%) were resistant to ampicillin followed by cotrimoxazole 115 (81.6%), amoxicillin-clavulanic acid 109 (77.3%), cefixime 99 (70.2%), cefepime 93 (66.0%) and tetracycline 91 (64.5%). The extended-spectrum beta-lactamase producing GNB were 69/124 (55.6%). Of which Klebsiella spp. 19 (15.3%) and E. coli 17 (13.7%) were common ESBL producers. Carbapenemase-producing isolates were 8/51(15.7%). Of which Enterobacter, Klebsiella and E. coli were common carbapenemase producers. CONCLUSION AND RECOMMENDATION: Multi-drug resistance and ESBL producing isolates in the present study were high. E. coli and Klebsiella spp. were the most common ESBL producing GNB. Klebsiella spp., Enterobacter spp., E. coli and Citrobacter spp. were typical carbapenemase-producing isolates. Continuous monitoring, antibiotic stewardship and molecular detection of the gene responsible for drug resistance are important means to reduce the spread of drug-resistant pathogens.

BACKGROUND: Malaria is a mosquito-borne infectious disease known to cause significant numbers of morbidities and mortalities across the globe. In Ethiopia, its transmission is generally seasonal and highly unstable due to variations in topography and rainfall patterns. Studying the trends in malaria in different setups is crucial for area-specific evidence-based interventions, informed decisions, and to track the effectiveness of malaria control programs. The trend in malaria infections in the area has not been documented. Hence, this study aimed to assess the five-year trend in microscopically confirmed malaria cases in Dembecha Health Center, West Gojjam Zone, Amhara national regional state, Ethiopia. METHODS: A health facility-based retrospective study was conducted in Dembecha Health Center from February to April 2018. All microscopically confirmed malaria cases registered between 2011/12 and 2015/16 were carefully reviewed from laboratory record books and analyzed accordingly. RESULTS: A total of 12,766 blood films were requested over the last five years at Dembecha Health Center. The number of microscopically confirmed malaria cases was 2086 (16.34%). The result showed a fluctuating yet declining trend in malaria infections. The highest number of cases was registered in 2012/13, while the lowest was in 2015/16. Males and age groups >20 constituted 58.9% and 44.2% of the patients, respectively, being the hardest hit by malaria in the area. Malaria existed in almost every month and seasons. Plasmodium falciparum was the predominant species. The highest peak of malaria infections was observed in the late transition (October-December) 799 (38.3%) and early transition (May-June) 589 (28.2%) seasons. CONCLUSION: Although the results indicate a fluctuating yet declining trend, the prevalence of confirmed malaria cases in the area remains alarming and indicates a major public health burden. Therefore, close monitoring and intervention measures to control malaria infections in the area and also to tackle the dominant species, Plasmodium falciparum, are necessitated accordingly.
RESUMO
INTRODUCTION: Hepatitis virus infection is a major public health burden and silent killer disease in sub-Saharan Africa, including Ethiopia. Therefore, this study aimed to investigate the prevalence of hepatitis B and C viruses and associated factors among pregnant women attending an antenatal clinic in three tertiary hospitals in Amhara National Regional State, Ethiopia. METHODS: A cross-sectional study was conducted among 1121 pregnant women. Data on sociodemographic and associated factors were collected using a structured questionnaire. Serum samples were tested for hepatitis B surface antigen (HBsAg) and anti-hepatitis C virus antibody (anti-HCV) using ELISA. SPSS version 20 was used for data analysis, and a multivariable logistic regression analysis was used to assess the relationship between factors associated with hepatitis B virus and hepatitis virus C infection. RESULTS: A total of 1121 pregnant women were included in the study. The mean age of study participants was 27.2 ± 4.8 yrs. The majority of pregnant women (895 (79.8%)) were from urban areas. The overall seroprevalence of HBsAg and anti-HCV antibody was 52 (4.6%) and 18 (1.6%), respectively. The coinfection rate of HBV/HCV was 1.4% (1/69). Ten (19.2%) of HBV positive cases were coinfected with HIV. There were no coinfections of HCV and HIV. Interestingly, pregnant women with a history of multiple sexual partners (AOR = 3.2, 95% CI, 1.7-7.6), blood transfusion (AOR = 7.6, 95% CI, 2.9-16.9), family history of HBV (AOR = 3.5, 95% CI, 1.7-7.6), being HIV-positive (AOR = 2.5, 95% CI, 1-5.9), and tattooing (AOR = 2, 95% CI, 1-3.8) were significant predictors of HBV infection. Similarly, young age (17-25 yrs) (AOR = 3.2, 95% CI, 1.8-8.6) and no educational background (AOR = 5, 95 CI, 1.7-14.8) were significant predictors of HCV infection. CONCLUSIONS: Hepatitis B and C viruses' infection was intermediate among pregnant women; some risk factors were significantly associated with the majority of cases. Infants born from these infected mothers are at risk of infection. This calls for screening and integration of HBV prevention of mother-to-child transmission (PMTCT) into HIV. Thus, the provision of health education on hepatitis B and C viruses' transmission, vaccination, and screening of all pregnant women routinely are essential for the prevention of these viruses.
RESUMO
BACKGROUND: Determination of the distribution pattern and associated factors of skin and soft tissue infections caused by methicillin-resistant Staphylococcus aureus (MRSA) is a fundamental step to set up an effective control program to improve the health status. The purpose of this study was to assess the antibiotic susceptibility pattern and associated factors of MRSA among dermatological patients. METHODS: In this hospital-based, prospective, cross-sectional study, 189 pus and skin swabs were collected from dermatological patients through a convenient sampling method in 2019. A structured questionnaire was employed for data collection of associated factors. Pus and skin swabs were collected using a sterile cotton swab and needle aspiration, then inoculated on mannitol salt agar. We followed a standard bacteriological procedure for identification of MRSA. Logistic regression models at a 95% confidence interval and p-value < 0.05 was considered for significance. RESULTS: A total of 127/189 (67.2%) of Staphylococcus aureus isolates were recovered and 80/127 (63.0%) were MRSA. Over 97% of Staphylococcus aureus isolates showed resistance to penicillin. MRSA was sensitive to gentamicin (78.75%), ciprofloxacin (83.75%), and clindamycin (86.25%). Frequency of washing body, method of hand washing, and recent hospitalization had a significant association with MRSA skin infection. CONCLUSIONS: The study revealed a high prevalence of MRSA among dermatological patients. Staphylococcus aureus showed a very high degree of resistance to different antimicrobials and most of Staphylococcus aureus isolates also showed multidrug-resistance patterns.

PURPOSE: Hepatitis B virus (HBV) infection is a major public health problem globally. Mother-to-child transmission (MTCT) of HBV is high in endemic countries; however, little is known about pregnant women`s knowledge and attitudes regarding MTCT and prevention methods in Ethiopia. Therefore, this study aimed to assess the knowledge, attitude and associated factors of pregnant women towards MTCT of HBV and its prevention in three tertiary hospitals in the Amhara region, northwestern Ethiopia. MATERIALS AND METHODS: A cross-sectional study was conducted from May 1, 2018 to September 30, 2019. A total of 1121 pregnant women participated in the study. A structured questionnaire was used to collect the sociodemographic, knowledge, and attitudes of pregnant women towards MTCT of HBV and its prevention. Data were analyzed using SPPS version 20. χ 2-test, multivariate logistic regression, Spearman correlation, and analysis of variance (ANOVA) were used for data analysis. RESULTS: The majority of 89.6%; 95% CI (87.9-91.3%) pregnant women had poor knowledge of MTCT of HBV and its prevention. However, more than half of the study participants had favorable attitudes. Only 141 (12.6%) of the pregnant women knew that HBV transmitted from mother-to-child and 169 (15.1%) knew that HBV had a vaccine. There was a significant difference in attitude between the three hospitals (P<0.001). In multivariable analysis, education, gravida and vaccination history were independent factors significantly associated with good knowledge and favorable attitudes while income and residence significantly associated only to knowledge and attitude, respectively. There was a significant positive correlation between the knowledge and attitude of pregnant women (P<0.001). CONCLUSION: The knowledge of pregnant women was found to be poor and their attitude was also limited to MTCT of HBV infection and its prevention. Educational status and vaccination history were predictors of knowledge and attitude, but income and residence only to knowledge and attitude, respectively. This study revealed a lack of knowledge in pregnant women for the prevention and control of MTCT of HBV. This calls for the Amhara Health Bureau and Ministry of Health to promote health education programs for pregnant women attending antenatal care on MTCT of HBV and its prevention methods to improve knowledge and attitudes.
RESUMO
BACKGROUND: Antiretroviral treatment has played a pivotal role in the reduction of HIV/AIDS-related morbidity and mortality. However, treatment options can be impaired by the development of antiretroviral treatment failure. Regular monitoring of the Human Immunodeficiency Virus treatment outcome via viral load tests is the key approach. There is a scarcity of information about HIV treatment failure and risk factors in the study area. Therefore, the study was aimed to assess antiretroviral treatment failure and associated factors among patients on first-line antiretroviral treatment at Tefera Hailu Memorial Hospital, Sekota, northeast Ethiopia. METHODS: A hospital-based cross-sectional study was conducted on 295 patients on first-line antiretroviral treatment from Nov. 2018 to Apr. 2019. Socio-demographic and clinical variables were collected using a pretested questionnaire, and blood specimen was collected for PCR viral load and CD4 + cell count estimation. Data were entered into Epi-Info and exported to SPSS for analysis. A binary logistic regression model was used to identify associated factors, and P value < 0.05 was considered as statistically significant. RESULTS: Of the 295 subjects on first-line ART, 49 (16.6%) and 18 (6.1%) experienced virological and immunological failures, respectively. The failure of the former was associated with poor adherence (AOR: 6.367, P < 0.001), CD4 + count < 500 cells/µL (AOR: 4.78, P = 0.031) and shorter (6-24 months) duration on ART (AOR: 0.48, P = 0.048), while poor treatment adherence (AOR: 11.51, P = 0.012) and drug interruption (AOR: 6.374, P = 0.039) were the independent risk factors for latter. Immunological tests to predict virological failures showed as sensitivity, specificity, PPV, and NPV were 20.4%, 96.7%, 55.5%, and 86.0%, respectively. CONCLUSIONS: The rate of ART failure was considerably high. Poor adherence, low CD4 + count, prolonged ART, and drug interruption were found to be the most predictor variables for virological and immunological failures. The discrimination power of the immunological parameter was low in comparison to virological measurements as standard methods. Therefore, the study highlighted the need for more attention and efforts to curb associated factors and maximize virological tests for monitoring treatment failures.

BACKGROUND: Updated information on multidrug-resistant bacteria is essential because multidrug-resistant bacteria are one of the most important current threats to public health and prevalence of multidrug-resistant bacteria varies from time to time. A large number of people die annually due to infections caused by multidrug-resistant pathogens, with millions more suffering from serious infectious complications. The aim of this study was to determine the rate of multidrug-resistant bacteria isolates among culture requested patients at University of Gondar Specialized Referral Hospital, Northwest Ethiopia. METHODS: A hospital-based retrospective cross-sectional study was conducted on all culture-positive patients' results at University of Gondar Specialized Referral Hospital, Northwest Ethiopia. RESULTS: Of the 2,161 bacterial isolates, the overall prevalence of multidrug-resistant bacteria was 40.5% (876/ 2,161). The multidrug-resistance rate of Gram-negative bacteria was 52.4% (493/942) and Gram-positive bacteria was 31.4% (383/1,219). From all isolates, 22.3% (481/2,161) were from wound discharge followed by 19.57% (428/ 2,161) from blood and 18.14% (224/2,161) from urine. The predominant bacteria isolated were S. aureus (44.1% (952/2,161)) followed by E. coli (16.6% (359/2,161)), Klebsiella species (13.2% (179/2,161)), and Citrobacter (4% (86/2,161)). The isolates showed high levels of resistance to ampicillin (81.99% (692/844)), cotrimoxazole (66.62% (531/797)), and penicillin (62.66% (381/608)) and lower resistance to vancomycin (6.79% (46/677)), amikacin (20% (18/95)), and nitrofurantoin (20.90% (21/110)). Primary MDR isolates were Serratia species (83.3% (5/6)), Enterobacter species (66.7% (20/30)), Klebsiella pneumonia (65.3% (89/176)), and Enterococcus species (57.1% (8/14)). The majority of MDR isolates were from inpatients (58.6% (p-value < 0.0001)), males (53.77%), age group < 2 years (30.7%), and blood sample (25.22%). CONCLUSIONS: A higher level of resistance to ampicillin, cotrimoxazole, penicillin and lower level of resistance to vancomycin, amikacin, and tobramycin were detected. Slightly lower overall rates of multidrug-resistant bacteria are isolated and a higher resistance rate is observed on Serratia species, Enterobacter species, K. pneumonia, Enterococcus species, and E. coli. Hospital admission is highly associated with the isolation of multidrug-resistant bacteria. Hence patient hospital stay should be considered in the prevention of multidrug resistant bacterial infections.

BACKGROUND: The liver is the major site of Hepatitis B virus and Hepatitis C virus replications. Patients with diabetes tend to be at an increased risk for developing various forms of liver diseases. The infection of the liver can cause or exacerbate diabetes. On the other hand, diabetes can cause or intensify the severity of liver infection. This comparative cross-sectional study was conducted with the aim to determine the prevalence of Hepatitis B and Hepatitis C virus infections and associated factors among patients with diabetes visiting the University of Gondar referral teaching hospital, northwest Ethiopia. RESULTS: Out of the 610 participants (305 patients with diabetes, 305 people with no diabetes) of the study, 65 (10.7%) were positive for Hepatitis infections, of whom 44 (14.4%) and 21 (6.9%) were positive for at least one of the viruses in patients with diabetes and people with no diabetes, respectively. Out of the diabetic and non-diabetic groups of the study, 26 (8.5%) and 14 (4.6%) (95% CI, 0.96-4.02) were positive for Hepatitis B virus, respectively, while 23 (7.5%) and 7 (2.3%) (95% CI, 1.46-8.68) of the diabetes and non-diabetic groups were positive for Hepatitis C virus, respectively. History of blood transfusion (95% CI, 1.36-12.71) and unprotected sex (95% CI, 1.25-10.15) were significantly associated with Hepatitis B virus infection, while the type of diabetes (95% CI, 1.25-10.89) was associated with anti-Hepatitis C virus positivity. CONCLUSION: Positivity for Hepatitis C virus was significantly associated with Type II diabetes. Blood transfusion and unprotected sex were risk factors for Hepatitis B virus infections. Further studies that elaborate temporal associations and find out explanations for the relationship between diabetes and Hepatitis C viral infections are of paramount importance.
RESUMO
OBJECTIVE: The aim of this study was to determine the level of drug resistance by gram-negative bacteria isolated from selected sewage polluted urban rivers in Addis Ababa, Ethiopia. RESULTS: From a total of 94 river water samples, 90 medically important gram-negative bacterial isolates were recovered to the species level. The predominant bacteria isolated were E. coli. 23 (26%) followed by K. pneumoniae 18 (20%), K. oxytoca 17 (19%). E. coli showed a high level of resistance to ampicillin 21 (91.3%), cefalotin, cefuroxime, ceftriaxone and cefepime 16 (70%). Both K. pneumoniae and K. oxytoca showed high resistance to ampicillin 16 (94%) and 17 (95%) respectively. Among identified bacterial species, most of them showed a multidrug-resistant pattern. Providential retigerri showed 100% multidrug resistance followed by P. alkalificiens (90%), E. coli (78%), M. morgani (75%), and C. frundi (60%).

BACKGROUND: Health workers are one of the most important building blocks of the health system. High turnover rate contribute to the shortfalls and unbalanced distribution of health personnel in the health workforce. Turnover intention is the strongest predictor of actual turnover. OBJECTIVE: To assess the magnitude of turnover intention and associated factors among health professionals working in public health institutions of North Shoa Zone, Amhara region, Ethiopia. METHODS: A health facility based cross-sectional study was conducted from March to April 2016, on 612 health professionals working in public health institutions of North Shoa Zone, Amhara region, Ethiopia, using a multistage stratified sampling technique. Data were collected using a pretested self-administered structured questionnaire. The data were entered using Epidata version 3.1 and analyzed using SPSS version 22 software. Descriptive statistics were conducted to summarize the sample characteristics. Backward stepwise logistic regression model was fitted and AOR with 95% CI was calculated to identify the associated factors. P-value <0.05 was taken as a cut-off point for statistical significance. Ethical issues were addressed. RESULTS: Among the 568 health professionals who responded to the questionnaire, 348 (61.3%) of them reported to have the intention to leave their current workplaces. The results showed that being a male [AOR = 1.496 (95% CI: 1.016, 2.204)], medical doctor [AOR = 0.318 (95% CI: 0.122, 0.824)], unsatisfied with the work nature [AOR = 1.822 (95% CI: 1.206, 2.753)], unsatisfied with the incentives [AOR = 1.668 (95% CI: 1.105, 2.517)], and unsatisfied with the supervision [AOR = 1.916 (95% CI: 1.274, 2.881)] and having low normative commitment [AOR = 2.176 (95% CI: 1.482, 3.196)] were significantly associated with turnover intention of the health professionals. CONCLUSIONS: The magnitude of turnover intention was high among health professionals working in public health institutions of North Shoa Zone. Health service managers and policymakers should develop evidence based retention strategies considering the determinants of health professionals' intention to leave.
