Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause pandemic of coronavirus disease 2019 (COVID-19). For many thousands of years, herbal products and dietary plants have been prescribed for various diseases by traditional healers. Thus, the aim of this review is to present main herbal products, their source, characteristics, and potential antiviral actions concerning COVID-19. Publications on herbal products related to antiviral effects were searched from different databases, such as Web of Science, Google Scholar, Medline, Scopus, and PubMed, until August 2021, using English key terms. According to different studies, there are so many important medicinal plants with antiviral activity, which can be used for viral infections or can be prescribed as supportive treatment. lack of information on the safety profile and amount of dose for different diseases is some of the limitations of medicinal plants. herbal medicine can interfere with COVID-19 pathogenesis by inhibiting SARS-CoV-2 replication and entry to host cells. Some of the antiviral medicinal plant species are citrus Spp., orange (C. Sinensis), Allium sativum, Allium cepa, Mentha piperita, and nigella sativa are the most desirable herbal drink or fruit that can introduce effective adjuvant components in COVID-19 management.

Veterinary drugs are pharmacologically and biologically active chemical agents. At present, veterinary drugs are extensively used to prevent and treat animal diseases, to promote animal growth, and to improve the conversion rate of feed. However, the use of veterinary drugs in food-producing animals may leave residues of the parent compounds and/or their metabolites in food products resulting in harmful effects on humans. To ensure food safety, sensitive and effective analytical methods have been developing rapidly. This review describes sample extraction and cleanup methods, and different analytical techniques are used for the determination of veterinary drug residues in milk and meat. Sample extraction methods, such as solvent extraction, liquid-liquid extraction, and cleanup methods such as dispersive solid-phase extraction and immunoaffinity chromatography, were summarized. Different types of analytical methods such as microbial, immunological, biosensor, thin layer chromatography, high-performance liquid chromatography, and liquid chromatography–tandem mass spectrometry were discussed for the analysis of veterinary drug residues in animal-derived foods. Liquid chromatography–tandem mass spectrometry is the most widely used analytical technique for the determination of antibiotic drug residues. This is due to the powerful separation of LC and accurate identification of MS, and LC-MS/MS is more popular in the analysis of veterinary drug residues.

Diabetes mellitus (DM) is a group of metabolic diseases characterized by hyperglycemia resulting from defects in insulin secretion, insulin action, or both. Thus, this study aimed to assess the prevalence and factors associated with HM use among DM patients A hospital-based cross-sectional study was conducted on 395 diabetic patients visiting the diabetes care service of Debre Tabor General Hospitalfrom August 1 to September 28, 2020. Interview guided self-administered questionnaire was used for data collection. Out of 395 diabetic patients, 231(58.5%) participants were used herbal medicine. The most dominant herbal products used were M.stenoptela (53.2%), N. sativa (42.0%), Z. officinale (32.5%), A. sativum (20.8%), A. vera (13.4%), P.gracilis(10.4%), T.schimperi(7.5%), V. amygdalina (5.2%), T. foenumgraecum(3.5%),and D.penninervum(2.2%).The odds of HM use in female participants were 1.98 times (AOR=1.98, 95% CI=1.72, 3.25) higher compared to male participants. The odds of HM use among participants who develop DM complications were 1.77 times (AOR=1.77, 95% CI=1.03, 2.83) higher than in participants without DM complications. The odds of HM use among participants with a family history of DM were 2.89 times (AOR=2.89, 95% CI=1.42, 3.19) higher than in participants without a family history of DM. The prevalence of herbal medicine use among diabetic patients was high. Educational level, gender, residence, educational level, duration of DM, presence of DM complication, and family history of DMwere the independent predictors' of HM use.

Background. The improvement of healthcare systems has brought the subsequent increase in people access to medications. The consumers are not able to use all the dispensed medications because of various reasons. The improper disposal of these unused medicines has led to environmental contamination to an alarming extent. Therefore, the study was conducted to assess the knowledge, attitude, and practice of unused medications disposal among patients visiting public health centers in Gondar town, Ethiopia. Methods. A descriptive cross-sectional study was conducted among 404 patients visiting public health centers in Gondar town, Ethiopia, from August to September 2021, by using standardized and a locally translated semistructured questionnaire. The data were entered and analyzed by using the SPSS version of 21.0. The variable of interest was described in the form of statements and tables. Result. Out of 404 respondents included in the study, 221 (54.7) of them were female. More than half (226 (55.9)) of the respondents had unused medicine at home. The common methods of disposal practice were throwing into a household garbage (150 (31.4)), followed by flushed into toilet/sinks (88 (21.8)). More than half (286 (70.8)) of the respondents knew about medication waste and 239 (59.2) of them checked their medication expiry date. More than half (215 (53.5)) of the participants strongly agreed that unused medicine can cause potential risk at home and 279 (69.1) of study participants strongly agreed that children are more vulnerable to the potential risk of unused medicine at home. Conclusion. There was a high practice of keeping medication at home, and most disposal approach indicated by the participants was not recommended methods. Awareness about the proper disposal of unused medicines among the public should be created. Guidelines on safe disposal are required, and an organized method of collecting unused and expired pharmaceuticals needs to be introduced.

Background: HIV/AIDS in resource-limited settings poses a high risk of occupational exposure to healthcare workers due to higher number of HIV infected patients. Hence, antiretroviral based post-exposure prophylaxis (PEP) for HIV is very crucial. The aim of the study was to determine the knowledge, attitudes, and practices of medical and Health science students on antiretroviral based HIV PEP in University of Gondar comprehensive specialized hospital (UOGCSH), Northwestern Ethiopia. Methods: An institutional-based cross-sectional study was conducted among 220 medical and health science graduating students in UOGCSH from May to July 2015. Data were collected using a self-administered pretested questionnaire. The collected data were analyzed using SPSS software version 22. Results were summarized in frequencies, percentages, and means with standard deviations and presented using tables or figures. Results: Among the respondents, only sixty-six (30%) of the 220 study participants has had adequate knowledge about HIV PEP. Furthermore, over 90 % of the students had positive attitude towards HIV PEP f. Out of the total respondents, 37/220 (16.8%) were in need of HIV PEP and of these students only 18/37 (48.6%) took PEP. On the other hand, merely 50% of the study subjects completed the full course of HIV PEP, while the rest 50% failed to finish. As to the respondents self-report, the sole reason for starting but failing to complete the full course of HIV PEP was intolerance to the side effects of antiretroviral. Conclusions: Although majority of the respondents had poor knowledge and practice, they owned a good attitude towards HIV PEP. Therefore, a pre-service intensive training for all students regarding HIV PEP prior to their clinical attachments is mandatory. In addition, potential side effects of ARTs and its managements should be priory informed to the students so as to prevent the associated non-adherence to ultimately reduce the incidence of drug resistance. Moreover, the habit of needle stick injury reporting was found to be poor that needs due improvement and there has been also a pressing need to supply sufficient protective barriers to the students while planning and rendering services.

Background: Inappropriate use of narcotic drugs is a growing worldwide health challenge. The problem is even worse in Sub-Saharan Africa where organized supply chain regulations on dispensing and stock management are poor for controlling these global challenges. Methods: A mixed method, descriptive cross-sectional and simulated client study design was used from September 10, 2020 to November 26, 2020 to assess the extent of utilization and compliance of narcotic drug dispensing in private pharmacy retail outlets of Gondar and Bahir Dar town of Amhara region, Ethiopia. A total of 107 private pharmacy outlets were on duty. But in simulated study, purposive sampling is a method that prioritizes study units having the data of interest. Results: A total of 107 private pharmacy retails outlets were included in the survey. The average compliance to the controlled prescription regulation of Ethiopia in all pharmacy outlets (107) of the five drugs were calculated and found to be poor, 23.9% (SD = 18.3%). Compliance to strong narcotics is extremely low, 3.3 % for pethidine and 8% for morphine. Religion of the professionals has significant association with compliance to the prescription of narcotic drugs (p < .001). Discussion: In the era of narcotic epidemics, as a result of growing global inappropriate use of controlled drugs, the finding of this study gives an insight for a serious and strict regulation in managing and controlling the overall distribution of the narcotic drugs. Conclusions: The compliance of the private retail pharmacies of Ethiopia to the regulation of controlled drugs is low.
