Eight selected wild vegetables from Nepal (Alternanthera sessilis, Basella alba, Cassia tora, Digera muricata, Ipomoea aquatica, Leucas cephalotes, Portulaca oleracea and Solanum nigrum) were investigated for their antioxidative potential using 2,2-dyphenyl-1-picrylhydrazyl (DPPH) scavenging, hydrogen peroxide (H2O2), ferric reducing antioxidant power (FRAP), and ferric thiocyanate (FTC) methods. Among the selected plant extracts C. tora displayed the highest DPPH radical scavenging activity with an IC50 value 9.898 μg/mL, whereas A. sessilis had the maximum H2O2 scavenging activity with an IC50 value 16.25 μg/mL—very close to that of ascorbic acid (16.26 μg/mL). C. tora showed the highest absorbance in the FRAP assay and the lowest lipid peroxidation in the FTC assay. A methanol extract of A. sessilis resulted in the greatest phenolic content (292.65 ± 0.42 mg gallic acid equivalent (GAE)/g) measured by the Folin–Ciocalteu reagent method, while the smallest content was recorded for B. alba (72.66 ± 0.46 GAE/g). The greatest flavonoid content was observed with extracts of P. oleracea (39.38 ± 0.57 mg quercetin equivalents (QE)/g) as measured by an aluminium chloride colorimetric method, while the least was recorded for I. aquatica (6.61 ± 0.42 QE/g). There was a strong correlation between antioxidant activity with total phenolic (DPPH, R2 = 0.75; H2O2, R2 = 0.71) and total flavonoid content (DPPH, R2 = 0.84; H2O2, R2 = 0.66). This study demonstrates that these wild edible leafy plants could be a potential source of natural antioxidants.
Background: Underreporting of adverse drug reactions (ADRs) is common globally, and Nepal is not an exception to this. Health-care professionals (HCPs) play a vital role in reporting ADR during routine practice. Lack of knowledge and awareness about pharmacovigilance and reporting ADRs among HCPs may contribute to underreporting. Objective: The objective of this study was to evaluate the knowledge and perception of HCPs regarding ADR reporting and pharmacovigilance in a tertiary care teaching hospital in, Nepal. Methods: A descriptive cross-sectional study was conducted. A questionnaire was distributed to 215 HCPs (medical doctors, nurses, and pharmacists) between March and September 2018. Knowledge and perception regarding ADR reporting and pharmacovigilance were studied. Data were analyzed using IBM SPSS Statistics for Windows, Version 21.0 (IBM Corp, Armonk, New York). Results: The HCPs included 75 medical doctors, 126 nurses, and 14 pharmacists. Majority of the participants were female (67%), and the majority of participants were not aware of pharmacovigilance. Among the participants, pharmacists were found to have better knowledge regarding pharmacovigilance. However, other HCPs (doctors and nurses) strongly agreed about the necessity of having adequate knowledge about pharmacovigilance. Out of 215, 57.7% agreed that the important benefit of reporting ADR was to identify safe drugs and improve patient safety. The main reasons for not reporting were – ADR reporting was not widely promoted by relevant authorities (47%), followed by not knowing where and how to report ADR (34.9%). However, other HCPs (doctors and nurses) strongly agreed about the necessity of having adequate knowledge about pharmacovigilance. Conclusions: The knowledge of HCPs on ADR reporting and pharmacovigilance was poor. Despite a low knowledge of ADR reporting and pharmacovigilance among HCPs, there was a positive perception that ADR reporting is necessary and ADR monitoring system should be established in the hospital. This study also highlights a need for future intervention studies focusing on educating HCPs about ADR and pharmacovigilance.
Coronavirus disease 2019 (COVID-19) is an infectious disease caused by a new species of β-coronavirus genus named severe acute respiratory syndrome coronavirus 2. The COVID-19 pandemic, which started in late 2019 and continues as at mid-2021, has caused enormous damage to health and lives globally. The urgent public health need has led to the development of vaccines against COVID-19 in record-breaking time. The COVID-19 vaccines have been widely rolled out for the masses by many countries following approval for emergency use by the World Health Organization and regulatory agencies in many countries. In addition, several COVID-19 vaccine candidates are undergoing clinical trials. However, myths, fears, rumors, and misconceptions persist, particularly in regard to adverse events. In this commentary, we describe the adverse events associated with COVID-19 vaccines and discuss why it is essential to have a functional adverse event monitoring system in this context.
Introduction: Community pharmacy services are an integral part of the healthcare system directly involved in providing safe and effective patient care services. Despite the beneficial role of the community pharmacist, limited research focusing on their roles and responsibilities have been conducted. Thus, a bibliometric study was carried out to give a bibliometric overview of publications on community pharmacy in Nepal. Method: This is a bibliometric review of published literature of articles on community pharmacy in Nepal. The extensive literature search was carried out using PubMed, Google Scholar, NepJol as the sources of data. The community-based articles published from January 1, 1992, up to December 31, 2018, were retrieved. The keywords or medical subject headings (MeSH) terms, such as “Community Pharmacy”, “Community Pharmacist”, “Community Pharmacies”, “Community Pharmaceutical Services”, “Community Pharmaceutical Service”, "Private Pharmacy" and "Retail Pharmacy" were used. Nepal was entered as a country affiliation. Result: A total of forty-seven articles were retrieved, of which 87.5% (N=47) were based on original research papers. The maximum number of an article published in a single year was 17.02% (The majority [8 (17.02%]) of articles were published in 2016. The average number of authors per article was 4.65 with a standard deviation of 2.33. These articles were published in 38 journals, of which 10 articles were published in the journal without the impact factor or Scimago Journal and Country Rank. Conclusion: Scientific publications from community pharmacy settings are scant in Nepal. Hence, more analytical research work should be carried out to enhance the community pharmacy services and to promote the quality use of medicines in Nepalese society.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
