Purpose: In 2020, in response to the emergence and global spread of the disease COVID-19, caused by a new variant of coronavirus 2019-nCoV, the government of India ordered a nationwide lockdown for 21 days, which was then extended to a total of over 50 days. The aim of this study is to assess the effect of the lockdown on ophthalmic training programs across India. Methods: An online survey was sent across to trainee ophthalmologists across India through various social media platforms. Results: In all, 716 trainees responded; the average age was 29.1 years. Results showed that majority of the respondents were enrolled in residency programs (95.6%; 685/716) and the others were in fellowship programs. About 24.6% (176/716) of the trainees had been deployed on 'COVID-19 screening' duties. Nearly 80.7% (578/716) of the trainees felt that the COVID-19 lockdown had negatively impacted their surgical training. Furthermore, 54.8% (392/716) of the trainees perceived an increase in stress levels during the COVID-19 lockdown and 77.4% (554/716) reported that their family members had expressed an increased concern for their safety and wellbeing since the lockdown began. In all, 75.7% (542/716) of the respondents felt that online classes and webinars were useful during the lockdown period. Conclusion: Our survey showed that majority ophthalmology trainees across the country felt that the COVID-19 lockdown adversely affected their learning, especially surgical training. While most found online classes and webinars useful, the trainees' perceived stress levels were higher than normal during the lockdown. Training hospitals should take cognizance of this and reassure trainees; formulate guidelines to augment training to compensate for the lost time as well as mitigate the stress levels upon resumption of regular hospital services and training. Going ahead, permanent changes such as virtual classrooms and simulation-based training should be considered.
To explore the diversity in the essential oil yield and composition of Valeriana jatamansi Jones (syn. V. wallichii DC) growing wild in Uttarakhand (Western Himalaya), 17 populations were collected from different locations and grown under similar conditions. Comparative results showed considerable variations in the essential oil yield and composition. The essential oil yield varied from 0.21 to 0.46% in the fresh roots and rhizomes of different populations of V. jatamansi. Analysis of the essential oils by GC (RI) and GC/MS and the subsequent classification by principal component analysis (PCA) resulted in six clusters with significant variations in their terpenoid composition. Major components in the essential oils of the different populations were patchouli alcohol (1; 13.4-66.7%), α-bulnesene (3; <0.05-23.5%), α-guaiene (4; 0.2-13.3%), guaiol (5; <0.05-12.2%), seychellene (6; 0.2-9.9%) viridiflorol (<0.05-7.3%), and β-gurjunene (7; 0.0-7.1%). V. jatamansi populations with contents of 1 higher than 60% may be utilized commercially in perfumery.
The terpenoid composition of the essential oils of 17 different populations of Origanum vulgare L., collected from wild populations and subsequently grown under similar conditions in the sub-temperate region of the Western Himalaya, was studied. Analysis by GC (RI) and GC/MS allowed the identification of 51 components, representing 90.15 to 99.94% of the total oil. The two classes of the phenolic compounds and the monoterpenoids were predominant in all the essential oils. On the basis of the major constituents, i.e., marker compounds, and by comparison of the results with previous reports, new chemotypes could be identified. Principal component analysis was performed to determine the chemical variability within the different populations of O. vulgare collected and grown under similar conditions. Based on the marker compounds, six chemotypes with significant variations in their terpenoid profile were noticed within the 17 populations.
This study attempts to investigate factors associated with involvement in substance abuse in Trinidad and Tobago, through a survey of 1603 secondary school students, aged fourteen to eighteen years. Analysis of the data using the Chi-square test indicates a significant association (p < .001) between involvement in substance abuse and the following factors: grades at school, importance of religious involvement, amount of spending money obtained, confidence placed in parents/peers, parental involvement in alcohol consumption and educational expectations. Generally, the study indicates that youth less committed to traditional values, show a greater tendency to be involved in substance abuse. Involvement also appears to be associated with low self esteem and low educational expectations.
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.
