COVID-19 vaccine acceptance and its determinants among residents of Ambo Town, West Shewa, Oromia Region, Ethiopia: cross-sectional survey.

Background: Vaccines against COVID-19 are critical for preventing and managing COVID-19 because immunization is one of the most active and cost-effective health strategies for infectious disease prevention. Knowing the community's willingness and factors affecting COVID-19 vaccine acceptance will support the design of effective promotion strategies. Therefore, this study was aimed at assessing COVID-19 vaccine acceptance and its determinants among the Ambo Town community. Method: A community-based, cross-sectional study was conducted using structured questionnaires from 1 to 28 February 2022. Four kebeles were selected randomly, and the systematic random sampling procedure was used to select the households. SPSS-25 software was used for data analysis. Ethical approval was received from the Institutional Review Committee of the College of Medicine and Health Sciences of Ambo University, and data were kept confidential. Result: Of the 391 participants, 385 (98.5%) of the respondents were not vaccinated for COVID-19, and around 126 (32.2%) of the respondents said that they would receive the vaccine if the government provided it. The multivariate logistic regression analysis revealed that males were 1.8 times more likely to accept the COVID-19 vaccine (adjusted odds ratio (AOR) = 1.8, 95% CI: 1.074-3.156) as compared to females. The acceptance of the COVID-19 vaccine was lower by 60% in those who tested for COVID-19 as compared to those who were not tested (AOR = 0.4, 95% CI: 0.27-0.69). Moreover, the participants who had chronic diseases were two times more likely to accept the vaccine. Acceptance of the vaccine was reduced by half among those who believed that there was a scarcity of data on its safety (AOR = 0.5, 95% CI: 0.26-0.80). Conclusion: The prevalence of COVID-19 vaccination acceptance was low. To enhance the acceptance of the COVID-19 vaccine, the government and different stakeholders should strengthen public education using mass media about the advantages of getting the COVID-19 vaccination.

Hepatoprotective Effects of Crude Stem Bark Extracts and Solvent Fractions of Cordia africana against Acetaminophen-Induced Liver Injury in Rats.

Cordia africana Lam (Boraginaceae) is widely used in Ethiopian folk medicine for the treatment of different types of liver disorders. Thus, this study aimed to investigate the hepatoprotective effects of an aqueous (CAAE), 80% methanol extracts of C. africana stem bark (CAME), and the solvent fractions of the methanol extract against acetaminophen (APAP)-induced liver injury in rats. Acute toxicity test and APAP-induced lethality test were done on mice of either sex, while APAP dose selection test was done on female rats. Male rats were used for hepatoprotective experiments and the liver injury was induced using 2 g/kg APAP given orally. Serum levels of the liver enzymes and total bilirubin (TB), as well as lipid profiles, were determined. Histopathological examination of the liver tissues was also conducted to confirm the findings of biochemical analysis. Intraperitoneal (i.p.) sodium pentobarbital (SPB)-induced sleeping duration was also used to determine the protective effect of the test substances. Oral administration of APAP resulted in a significant increase in serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), TB, low-density lipoprotein (LDL), total cholesterol (TC), and triglycerides (TGs) and decrease in serum high-density lipoprotein (HDL). Administration of the standard drug, silymarin 100 mg/kg, extracts at doses of 100, 200, and 400 mg/kg and fractions at the dose of 400 mg/kg reversed the serum levels of all parameters to normal. CAME exerted a significant dose-dependent hepatoprotective effect in terms of ALT and AST, while CAAE significant dose-dependent hepatoprotective effect was in terms of AST, ALP, and TGs. The protective effect of the extracts and fractions was also confirmed by histopathological investigations and SPB-induced sleeping time. From the results of the present study, it can be concluded that C. africana stem bark aqueous, 80% methanol crude extracts, and solvent fractions of the methanol extract showed hepatoprotective effects.

Drug use evaluation in pregnant women attending antenatal care in Shashemene Referral Hospital, Oromia Regional State, Ethiopia.

OBJECTIVES: The main aim of this study was to estimate relative proportions of medication use according to different pregnancy risk categories (A, B, C, D, X) among pregnant women attending antenatal care (ANC) visits at Shashemene Referral Hospital. METHODS: A hospital-based retrospective cross-sectional study was conducted at Shashemene referral hospital from February 2016 to February 2017. Structured data collection form was used to capture data from patient medication cards. SPSS version 16.0 was used to analyze the results after entering and importing from MS-Excel. RESULTS: A total of 317 pregnant women cards were collected and assessed during the study period in May, 2017. Most, 208(65.6%), of the pregnant women were in their second trimester of pregnancy followed by third trimester, 78(24.6%). Tetanus prevention in pregnancy, 274(86.4%), was the most common reason for drug use. Number of medications prescribed was highest, 384(68.2%), in second trimester followed by third trimester, 130(23.1%). More than half, 305(54.2%), of the drugs prescribed were under category C, tetanus toxoid (TT) vaccine alone accounting for 274 (89.8%) of them, followed by 36.8% from category A. CONCLUSION: Vaccines, vitamins and minerals were the most frequently prescribed medications. The overall drug use condition during pregnancy in this study was inappropriate as more than half of the prescribed medications were from category C. On the other hand, category X medications were not prescribed.
