A COMPARATIVE STUDY OF GOVERNMENT AND PRIVATE ELEMENTARY SCHOOLS STUDENTES’ ENGLISH SPEAKING SKILLS IN WOLKITE CITY ADMINISTRATION
(wolkite University, 2021-11) MOHAMMED JEMAL SHAFI
This research is a comparative study about wolkite city administration government and private elementary schools’ students’ speaking skills. To achieve the objectives of the study 150 government and private schools’ students and 10 teachers were randomly selected from six schools (i.e. three governments and three private). In this study, the questionnaire and classroom observation were used as the major tool for data collection, and interview was used to cross check the results of the data collected from questionnaires. To know teachers’ teaching speaking skill, 24 questions were prepared and distributed for ten teachers. On the other hand, to know students’ learning of speaking skill, 17 questions were prepared and distributed for 150 students. All the questionnaires for both teachers and students were filled and returned. To see how speaking instructions are conducted, an observation checklist was prepared. The observation checklist contains eight evaluation criteria. In the analysis of the data, simple statistical procedures were used which made the interpretation and discussion of the results easier and clearer. The discussion was made by making use of percentage and the result of all the three tools were triangulated. The study reached a finding that indicates private schools’ students have better speaking skills, they are practiced speaking whenever and where ever they can after school, with any English speaker. However, government schools’ students have poor speaking skill and speaking instructions were not conducted properly teachers should prepare interesting speaking lessons that can capture learners’ attention. Given enough time for practice to their students. Teachers should use teaching materials, and should act as facilitators not dominator or silent sitter in language class room.

RESPONSE OF CHICKPEA TO POTASH AND NPSB FERTILIZERS AT SODO DISTRICT, GURAGE ZONE
(wolkite University, 2023-08) HAILEMARIAM TEKLU WILLISO
Lack of NPSB fertilizer and Muriate of Potash (MOP) is the key yield restrictive factors of chickpea production on verti sols in the Sodo District. Hence, a field experiment was carried out through the main cropping season of 2021/22 in Sodo District, to investigate the effect of blended NPSB fertilizer and Muriate of potash rates on yield and yield components of chickpea at Sodo District. At a four levels of blended NPSB fertilizer (0, 50, 100 and 150 kg ha-1 ) and four level of Muriate of Potash (MOP) (0, 50, 100 and 150). The experiment was conducted in a factorial combination in randomized complete block design with three replications. Data on the effect of blended NPSB fertilizer and Muriate of Potash rates on yield and yield components of chickpea were recorded and subjected to analysis of Variance (ANOVA). ANOVA showed that crop phenology (days to 50% flowering and days to physiological maturity), the growth (plant height, number of primary and secondary branches, shoot fresh and dry weight, root fresh and dry weight), nodulation (number of nodules, nodule fresh and dry weight, nodules volume, number of effective nodules) and yield components (number of pods, number of seeds per pod, hundred seed weight, harvest index and grain yield) were significantly affected by the different factor combinations. The highest mean value of seed yield (1953.33 kg ha-1 ) was gained from combined application rate of 100 kg NPSB ha-1 and 100 kg MOP ha-1 which increase over the control (886.67 kg ha-1 ). The partial budget analysis revealed that the maximum (ETB 63132.5ha-1 ) net benefit were achieved from interaction rate of 100 kg NPSB ha-1 and 100 kg Mop ha-1 MRR of 5.74% and minimum (ETB 31653.5 ha-1 ) net benefit were obtained from the control, respectively. Hence, with the interaction rate of 100 kg NPSB ha-1 and 100 kg Muriate of Potash ha-1 could be tentatively recommended for chickpea production in Sodo District. However, the trial should be repeated over years and sites to give a valid recommendation.

SPECTRUM OF CARDIOVASCULAR DISEASE ADMISSIONS, OUTCOME, AND ASSOCIATED FACTORS IN WOLKITE UNIVERSITY COMPREHENSIVE SPECIALIZED HOSPITAL, CENTRAL ETHIOPIA: RETROSPECTIVE STUDY
(wolkite University, 2026-06) Dr. Tarekegn Murezha
Background: Cardiovascular diseases are the leading cause of death globally, with approximately 80% of these deaths occurring in low- and middle-income countries, including Ethiopia. Despite this growing burden, there is a significant lack of localized data on the clinical profile, outcomes, and associated factors of cardiovascular disease admissions in many regions of the country, including the study area. This study seeks to fill that gap by providing crucial evidence from a tertiary care setting. Objective: To assess the clinical spectrum, admission outcomes, and determinants among patients admitted with cardiovascular diseases at Wolkite University Comprehensive Specialized Hospital. Methods: An institution-based retrospective cross-sectional study was conducted among 357 cardiac patients admitted to Wolkite University Comprehensive Specialized Hospital from September 1, 2022, to September 1, 2025. A systematic random sampling method was applied, and all eligible medical records were reviewed from this period. Data on types of cardiovascular diseases, clinical presentation, diagnostic results (including echocardiography), treatment, and inhospital outcomes were collected using a pre-tested, structured data extraction checklist. Data were entered into Epi-Data version 4.6 and then exported to SPSS version 27 for statistical analysis. Descriptive statistics (frequencies, percentages, means, and standard deviations were used to summarize the burden and spectrum of cardiovascular disease. Bivariate analyses and multivariable logistic regression were used to identify factors associated with admission outcomes. A p-value of less than 0.05 at 95% CI was considered statistically significant. Results: A total of 357 cardiovascular disease admissions were included in the analysis. The most common cardiovascular diagnoses were Stroke, heart failure, and ischemic heart disease. The overall in-hospital mortality rate was 10.9%. Among the independent factors, hemorrhagic stroke (AOR = 7.92, P = 0.004) and ICU admissions (AOR =5.45, P = 0.020) are associated with unfavorable outcomes. Conclusion: The study area has a high prevalence of cardiovascular diseases, which significantly increases morbidity and mortality. Overall, this study demonstrates an increasing burden of stroke and heart failure among patients admitted for cardiovascular disease in Gurage zone. The majority of cardiovascular diseases involve potentially modifiable risk factors that may have stopped or slowed the disease’s progression. Among the independent variables hemorrhagic stroke and ICU admissions were associated with poor admission outcome.

GLYCEMIC CONTROL AND ITS DETERMINANTS AMONG TYPE 2 DIABETES PATIENTS AT PUBLIC HOSPITALS IN GURAGE ZONE, CENTRAL ETHIOPIA, 2025.
(wolkite University, 2025-06) Dr. YONAS GIRMA
Background: Poor glycemic control is a major public health issue among patients with type 2 diabetesmellitus and it is a significant risk factor for the progression of diabetic complications. Numerous studieshave documented the importance of glycemic control and the factors that influence it. However; as of the studies done previously in Ethiopia the result are wide in terms of magnitude and its determinants. This study aimed to assess the magnitude and its determinant factors of poor glycemic control among type 2diabetes patients public hospitals of Gurage zone, central Ethiopia. Methods and materials: A hospital-based cross-sectional study was conducted among 316 patients withtype 2 diabetes mellitus attending follow-up clinics at public hospitals in the Gurage Zone from November to December 2025. Study participants were selected using a systematic probability sampling technique, andall eligible patients who met the inclusion criteria were included. Data were collected through face-to-faceinterviews using a structured questionnaire and by reviewing patients’ medical charts. The data were entered into EpiData version 3.1 and exported to SPSS version 23 for analysis. Descriptive statistics wereused to summarize the data, while bivariate and multivariable logistic regression analyses were performedto identify factors associated with glycemic control. Results: Among the 316 study participants, 216 (68.4%) had poor glycemic control and 100 (31.6%) hadgood glycemic control. Longer duration of diabetes (AOR = 4.12; 95% CI: 1.73–9.80), poor medicationadherence (AOR = 7.64; 95% CI: 3.59–16.28), non-adherence to dietary recommendations (AOR = 2.55;95% CI: 1.15–5.65), and older age (AOR = 6.38; 95% CI: 2.41–16.86) were independently associated withincreased odds of poor glycemic control. Access to a health care facility was associated with reduced odds of poor glycemic control (AOR = 0.25; 95% CI: 0.12–0.54). Diabetic complications, comorbidity status, and community-based health insurance were not significant in the adjusted analysis. Conclusion and Recommendations: Poor glycemic control was highly prevalent among patients with type 2 diabetes mellitus in Gurage Zone public hospitals. Longer duration of diabetes, poor medication and dietary adherence, older age, and who lack access to health care facilities were significant predictors of poor glycemic control. Strengthening patient education on adherence, improving access to chronic care services, and prioritizing high-risk groups are essential to improve glycemic outcomes

POOR OUTCOMES OF ILEOSIGMOID KNOTTING AND ASSOCIATED FACTORS AMONG ADULT PATIENTS OPERATED AT WOLKITE UNIVERSITY COMPREHENSIVE SPECIALIZED HOSPITAL: A CROSS-SECTIONAL STUDY (JANUARY1, 2020 – DECEMBER 31, 2025)
(wolkite University, 2026-06) DR SINTAYEHU BEKELE
introduction Ileosigmoid knotting (ISK) is a rare but unique life-threatening surgical emergency in which a loop of the ileum and the sigmoid colon wrap around each other. The aim of this study was to evaluate poor outcomes and associated factors among adult patients operated for ISK. Methods This is institution-based cross-sectional study conducted at Wolkite University Comprehensive Specialized Hospital in Wolkite, Central Ethiopia. The study reviewed medical records over a six-year period, from January 1, 2020, to December 31, 2025, and included 54 adult patients who underwent surgery for ileosigmoid knotting. Secondary data were extracted from patient medical records and analyzed using SPSS version 27. A p-value of <0.05 was considered statistically significant. ResultsOf the 54 patients, 50 (92.5%) had complete medical records and were included in the analysis. Poor postoperative outcomes occurred in 23 patients, giving a proportion of 46%(95% CI: 31.8%–60.7%). Age (AOR=2.05, 95% CI: 1.03–4.07), bowel gangrene (AOR=3.84,95% CI: 1.46–10.10), preoperative shock (AOR=4.34, 95% CI: 1.48–12.69), and prolonged duration of symptoms (AOR=11.03, 95% CI: 2.69–45.20) were independently associated withpoor postoperative outcome. Conclusions and recommendations Nearly half of the participants had poor postoperative outcome. It is associated with advance age, delayed presentation, preoperative shock, and presence of bowel gangrene. Early recognition, prompt surgical intervention, and aggressive perioperative optimization, and stoma creation in double bowel gangrene are essential to improve outcomes.
