Abstract: Background . Accumulating evidence suggests that patients with type 2 diabetes mellitus and hyperinsulinemia are at an increased risk of developing malignancies. It remains to be fully elucidated whether the use of metformin, an insulin sensitizer, and/or sulfonylureas, insulin secretagogues, affects cancer incidence in subjects with type 2 diabetes mellitus. Objective . A systematic review and meta-analysis was performed to compare the risk of cancer incidence associated with monotherapy with metformin compared with monotherapy with sulfonylureas in type 2 diabetes mellitus patients. Methods . Search was performed throughout MEDLINE/PubMed, EMBASE, Google Scholar, Cochrane Central Register of Controlled Trials (CENTRAL), and ClinicalTrials.gov up until December 2018. In this meta-analysis, each raw data (unadjusted) and study-specific (adjusted) relative risks (RRs) was combined and the pooled unadjusted and adjusted RRs with the 95% CI were calculated using the random-effects model with inverse-variance weighting. Heterogeneity among the studies was evaluated using I 2 statistics. Publication bias was evaluated using the funnel plot asymmetry test. The Newcastle-Ottawa scale (NOS) was used to assess the study quality. Results . A total of 8 cohort studies were included in the meta-analysis. Obvious heterogeneity was noted, and monotherapy with metformin was associated with a lower risk of cancer incidence (unadjusted RR = 0.74 , 95% CI: 0.55-0.99, I 2 = 97.89 % , p 0.00001 adjusted RR = 0.76 , 95% CI: 0.54–1.07, I 2 = 98.12 % , p 0.00001 ) compared with monotherapy with sulfonylurea, using the random-effects model with inverse-variance weighting. Conclusions . According to this review, the monotherapy with metformin appears to be associated with a lower risk of cancer incidence than monotherapy with sulfonylurea in patients with type 2 diabetes. This analysis is mainly based on cohort studies, and our findings underscore the need for large-scale randomized controlled trials to establish the effect of metformin monotherapy, relative to sulfonylureas monotherapy on cancer.

Abstract: Introduction . Tuberculosis remains a major public health threat throughout the world particularly in developing countries. Evaluating the treatment outcome of tuberculosis and identifying the associated factors should be an integral part of tuberculosis treatment. Objectives . The aim of this study was to assess the treatment outcome of tuberculosis and its associated factors among TB patients in the TB clinics of Harar public hospitals, Eastern Ethiopia, 2017. Methods . A retrospective document review was conducted in two public hospitals of Harar town, located 516 km east of Addis Ababa. A systematic random s ling technique was used to select the document of TB patients who were registered in the hospitals from 1st of January, 2011, to 30th of December, 2015. The data were collected using a pretested structured data extraction format. SPSS Version 21 for window was used for data processing. Bivariate and multivariate analysis with 95% confidence interval was employed in order to infer the associations between TB treatment outcome and potential predictor variables. Results . One thousand two hundred thirty-six registered TB patients’ documents were reviewed. Of these, 59.8% were male, 94.2% were urban dwellers, 97% were new cases, 61.2% were presented with pulmonary TB, and 22.8% were HIV positive. Regarding the treatment outcome, 30.4% were cured, 62.1% completed their treatment, 3.9% died, 2.4% were defaulted, and the remaining 1.2% had failed treatment. The overall rate of the treatment success among the patients was 92.5%. In the present study, being female (AOR = 1.89, 95% CI: 1.14 - 3.14), having pretreatment weight of 20 – 29 kg (AOR = 11.03, 95% CI: 1.66 - 73.35), being HIV negative (AOR = 6.50, 95% CI: 3.95 - 10.71), and being new TB patient (AOR = 3.22 95% CI: 1.10 - 9.47) were factors independently associated with successful treatment outcome. On the other hand, being in the age group 54 – 64 years (AOR =10.41, 95% CI: 1.86 - 58.30) and age greater than 65 years (AOR =24.41, 95% CI: 4.19 - 142.33) was associated with unsuccessful TB treatment outcome. Conclusion . In the current study, the rate of successful TB treatment outcome was acceptable. This rate should be maintained and further improved by designing appropriate monitoring strategies.

Abstract: Examining pre-diabetes and diabetes rates using glycated haemoglobin (HbA Epidemiological study of HbA1c measurements in in iduals ≥18 years receiving a blood test (1) in the hospital setting of the ED at Blacktown/Mt Druitt hospital (1/06/2016 to 31/05/2018) and (2) in primary care involving Bridgeview Medical Practice (BVMP) (1/03/2017 to 01/02/2018) as well as other general practices (June 2018 only). Totals of 55,568 in iduals from ED and 5911 in iduals from GP. The prevalence of diabetes in tested in iduals was 17.3% (n = 9704) in ED and 17.4% (n = 1027) in GP. The prevalence of pre-diabetes in ED was 30.2% (n = 16,854) and 26.6% (n = 1576) in GP. Regression controlling for age, season, and gender revealed a weekly increase of 1.1% in odds for diabetes and 1.5% for pre-diabetes (p < 0.001), in line with the yearly absolute increase of 1% in rate for both tested and coded hospital patients. In BVMP the rate of diabetes rose by 22% during the testing period from 8.9% to 11%. There exists a high burden of diabetes both in hospitals and general practice. Testing in ED and general practice revealed similarly high burdens of diabetes across different areas of the healthcare system. In the appropriate hospital and primary care setting, HbA1c can be used to identify in iduals with diabetes that may benefit from targeted intervention.

Abstract: Purpose . Self-medication practice is often associated with irrational medication use. The aim of this study was to assess self-medication practices among community of Harar City and its surroundings, Eastern Ethiopia. Methods . A cross-sectional study was conducted through exit interview in selected drug outlets of Harar City among 370 clients from March to April, 2017. The data was coded and entered into epi-data and processed and analyzed using SPSS version 20. Results . Many participants practiced self-medication to alleviate their headache (30.30%), to treat their respiratory disorders (29.50%), and to treat their gastrointestinal disorders (27%). More than half (57.8%) of study participants declared that they were practicing self-medication due to prior experience and seeking less expensive service (20.50%). Two-fifths of them (40.3%) reported pharmacy professionals as source of information while 18.9% of respondents were advised by neighbors, friends, or relatives. About one-third (31.9%) of them did not have any source of information for self-medication practice. The most common type of drug used for self-medication by the participants was analgesic (42.2%). Approximately one-third (31.1%) of the subjects were expecting to be counseled by the pharmacy professionals about the drug side effects and to be helped in selecting their self-medication drug (30.3%). Conclusion . Varieties of medications were used among study participants ranging from antipain to that of antibiotics for different complaints including headache, respiratory complaints, and gastrointestinal problems. Experience with drugs and diseases as well as affordability were frequently reported reasons for self-medication practice. Participants had different views toward the role of pharmacy professionals. Hence, it is very important to educate patients on responsible use of medications and create awareness on the role of pharmacist in self-selected medication use in community.

Abstract: Despite the successes of treatment with antiretroviral therapy in reducing morbidity and mortality among HIV-infected patients, long-term sustainability of the initial regimen has become challenging. Therefore, this study is aimed to address pattern of and reasons for change of antiretroviral therapy regimens among HIV/AIDS patients at Jugel Hospital, Eastern Ethiopia. A retrospective cross-sectional study was conducted to review medical records of 220 patients who had been on treatment and experienced regimen change at least once from September 2006 to August 2016. Structured data abstraction format was customized from World Health Organization guideline. Data were entered in Epi-data version 3.1, and exported to and analyzed with Statistical Package for Social Sciences version 20. Following descriptive statistics, binary logistic regression was run to determine the association between selected variables and second-time regimen change. The mean age of patients was 37.6 (±8.9) years and 62.3% of them were female. Majority of the patients were presented to the hospital with World Health Organization clinical stage III (59.1%) and CD4 count below 200 cells/mm 3 (68.6%). The mean duration of stay on initial regimen was found to be 3.26 (±1.92) years. The average number of initial regimen changes per year was 22 (±11.28). In two-thirds (66.36%) of the patients, their initial regimen was changed to tenofovir disproxil fumarate–based alternatives. The most-frequent reason for initial regimen change was toxicity (32.3%). Among those who experienced the regimen change for the first time, the prevalence of second-time regimen change was found to be 18.18%. Patients who had been taking tuberculosis treatment along with antiretroviral therapy were more likely to get their regimen changed for the second-time compared to those who were not infected with tuberculosis (adjusted odds ratio: 3.40 95% confidence interval: 1.87–6.47). Besides, patients who were on zidovudine-based (adjusted odds ratio: 0.26 95% confidence interval: 0.33–0.47) and tenofovir disoproxil fumarate–based regimens (adjusted odds ratio: 0.03 95% confidence interval: 0.01–0.12) were less likely to get their regimen changed for the second-time compared to those who were on stavudine-based regimens. The majority of the patients had their treatment regimen changed because of drug-related toxicities, treatment failure, and comorbid conditions. Some regimen changes might be attributable to failure of either hospital supply system or patient-related factors which would have been prevented considering limited number of treatment options. There must be consideration of risks and benefits prior to changing a particular regimen.

Abstract: The bidirectional relationship between the twin epidemics of Tuberculosis (TB) and Human Immunodeficiency Virus (HIV) causes major global health challenges in the twenty-first century. TB-HIV co-infected people are facing multifaceted problems like high lost to follow up rates, poor treatment adherence, high TB recurrence rate, and high mortality risk. Our objective was to a ssess the outcomes of TB treatment and associated factors among TB-HIV co-infected patients in Harar town, Eastern part of Ethiopia , 2018. A retrospective study was conducted among systematically selected 349 TB/HIV co-infected patients who registered from 2012 to 2017 in two public hospitals in Harar town. The data were collected through document review by using a pre-tested structured data extraction checklist. The data were analyzed using SPSS Version 21. Bivariate and multivariate logistic regression were determined at 95% confidence intervals. Among the 349 TB/HIV co-infected patients included in the study, 30.1% were cured, 56.7% had completed their treatment, 7.7% died, 1.7% were lost to follow up, and 3.7% were treatment failure. Overall, 86.8% of the TB-HIV co-infected patients had successful TB treatment outcomes. The patients who were on re-treatment category (AOR = 2.91, 95% CI: 1.17–7.28), who had a history of opportunistic infection (AOR = 3.68, 95% CI: 1.62–8.33), and who did not take co-trimoxazole prophylaxis (AOR = 3.54, 95% CI: 1.59–7.89) had 2.91, 3.68, and 3.54 times higher odds of having unsuccessful TB treatment outcome than their counterparties, respectively. The chance of unsuccessful TB treatment outcome was 4.46 (95% CI: 1.24–16.02), 5.94 (95% CI: 1.87–18.85), and 3.01 (95% CI: 1.15–7.91) times higher among TB/HIV patients in stage 2, 3 and 4 than those in stage 1, respectively. The overall rate of the success of the TB treatment among TB-HIV co-infected patients in this study was higher compared with many previous studies. TB/HIV patients with a history of previous TB treatment, smear-positive pulmonary TB, late HIV stage, history of opportunistic infection and not being on co-trimoxazole prophylaxis therapy were at a high risk of getting poor treatment outcomes.

Abstract: Critically ill patients with moderate-to-severe physiologically stressful event are at high risk of developing stress ulcers. The use of pharmacological prophylaxis significantly reduces the incidence of stress ulcer in high-risk patients. The aim of this study was to assess the use of pharmacological prophylaxis for stress ulcer in the medical wards of University of Gondar Hospital. A cross-sectional study design was used. In total, 234 patients were selected through simple random s ling technique. The risk of stress ulcer development was assessed using Evidence-Based Medicine Guideline for stress ulcer prepared by Orlando Regional Medical Center. SPSS version 21 was used for data analysis. The most common acute risk factor to stress ulcer was coagulopathy (18.4%), followed by hypoperfusion (9.8%). The concomitant non-steroidal anti-inflammatory drug use (16.7%), mild-to-moderate brain or spinal cord injury (11.1%), and concomitant or recent corticosteroid use (9.4%) were frequently seen risk factors that necessitate administration of a prophylaxis. In total, 82 (35%) study participants were given stress ulcer prophylaxis, among which 52 (63.4%) were given without indication. The most commonly used drug class in the prevention of stress ulcer was proton pump inhibitors (76/82, 92.7%). In total, 43 (18.4%) study subjects were not given stress ulcer prophylaxis while there was clear indication. Patients with a long hospital stay and a diagnosis of central nervous system disorders had significant risk for inappropriate stress ulcer prophylaxis use. In this study, inappropriate use of prophylaxis for stress ulcer was common. The higher proportion of inappropriateness was due to the use of stress ulcer prophylaxis while there was no enough indication. We recommend future researchers to assess the cost and impact of inappropriate stress ulcer prophylaxis use, and the physicians should be adherent to the standard guidelines.
