Background: To confirm effective preventive practice and reduce the risk of COVID-19 data on knowledge, attitude, and preventive practices (KAP) are essential. Therefore, the current study was designed to evaluate the KAP of COVID-19 among people with hypertension (HTN) and/or diabetes mellitus (DM) attending public health facilities in Ambo town. Patients and Methods: Institutional-based cross-sectional study design was done among patients with HTN and/or DM from June 2020 to September 2020 at Ambo University Referral Hospital (AURH) and Ambo General Hospital (AGH). To identify the associated factors with poor practice and knowledge, logistic regression analyses were used. Results: The mean age of the study respondents was 44.6 years (± 9.84) of which the majority were male 235 (55.6%) and 159 (37.59%) of the participants had good knowledge. Concerning attitude, 335 (79.2%) have strongly believed that DM and HTN patients were more at risk of death because of COVID-19. Only 44 (10.4%) of them had a good level of COVID-19 prevention practice measures. Patients who use the source of information daily were 54.4% less likely to have poor knowledge about COVID-19 than those who use it weekly. Participants with no formal education were 3 times more likely to have poor COVID-19 prevention practice than those who were with formal education, and participants who have poor knowledge about COVID-19 were 2 times more likely to have poor COVID-19 prevention practice than those who have knowledge. Conclusion: The prevalence of poor knowledge about COVID-19 was low, and only less than ¾ of the participants strongly believed COVID-19 as a serious disease. A small percentage of participants had a good level of COVID-19 prevention practice. Good knowledge had an association with a good level of prevention practice. So, health sectors should work to increase accessibility of COVID-19 information.

Introduction: Diarrhea is a cause of morbidity and mortality, especially in children. Patients with diarrhea have been suffering from limited treatment options due to poor drug tolerance, side effect, and multi-drug resistance to almost all the current drug treatments. Therefore, it is important to search for a new therapeutic medicine that can effectively prevent the disease and safe. Vernonia amygdalina is an indigenous medicinal plant used traditionally for the treatment of diarrhea in Ethiopia. The aim of this study was therefore to confirm the antidiarrheal activities of 80% methanol leaves extract using mice models. Materials and Methods: The antidiarrheal activities of the 80% methanol leaves extract were investigated using castor oil-induced diarrhea, intestinal motility, and enteropooling models in mice. The negative control received distilled water orally, the test groups received three dose levels (100, 200, and 400 mg/kg) of the plant materials, and the positive control is given 3 mg/kg Loperamide orally. Results: In the castor oil-induced diarrheal model, the extract delayed onset of diarrhea and reduced fecal parameters at all tested doses significantly as compared with the negative control. Results from the charcoal meal test revealed that the extract produced a significant anti-motility effect at all tested doses as compared with the negative control. In the enteropooling test, the extract produced a significant decline in the volume and weight of intestinal contents. The observed antidiarrheal activity could be associated with the phytochemicals present in this plant extract. It was also observed that the extracts have shown no acute toxicity at a dose of 2 g/kg. Conclusion: This study provides the antidiarrheal activity of the crude extract in all three models. Hence, the findings provide scientific support for the traditional use of Vernonia amygdalina leaves as treatment of diarrhea.
