Facing COVID-19: Psychological Impacts on Hospital Staff in a Tertiary Care Private Hospital in India.

Objective: To investigate the prevalence of depression, anxiety, and insomnia among hospital staff working in a tertiary care private hospital in India during the early period of the coronavirus disease 2019 (COVID-19) pandemic.

Methods: This cross-sectional study was conducted May 5-25, 2020, among 347 hospital staff (nursing and other hospital staff, with the exception of doctors). Depression, anxiety, and insomnia were measured using the 9-item Patient Health Questionnaire, the 7-item Generalized Anxiety Disorder Scale, and the Insomnia Severity Index, respectively.

Prevalence and Determinants of Substance Use Among Indigenous Tribes in South India: Findings from a Tribal Household Survey.

Background: Indigenous populations have higher substance use than non-indigenous populations. Current evidence on indigenous substance use is largely derived from national household surveys, while there are no specifically designed, culturally specific methodological studies available to determine the prevalence of substance abuse among the indigenous tribes. The present study examined the prevalence and predictors of alcohol use, smoking, and betel quid chewing among indigenous tribes in South India.

Factors Associated with Alcohol Misuse among Indigenous Tribal Men in Wayanad: A Qualitative Study.

Background: Disproportionate level of alcohol misuse is reported among indigenous people all over the world. A few available studies from India also support higher alcohol misuse among tribal men, but the reason for it is largely unexplored. Thus, we explored the factors associated with alcohol misuse among indigenous tribal men in Wayanad, Kerala.

Femtosecond laser ablation-based mass spectrometry: An ideal tool for stoichiometric analysis of thin films.

An accurate and routinely available method for stoichiometric analysis of thin films is a desideratum of modern materials science where a material's properties depend sensitively on elemental composition. We thoroughly investigated femtosecond laser ablation-inductively coupled plasma-mass spectrometry (fs-LA-ICP-MS) as an analytical technique for determination of the stoichiometry of thin films down to the nanometer scale. The use of femtosecond laser ablation allows for precise removal of material with high spatial and depth resolution that can be coupled to an ICP-MS to obtain elemental and isotopic information.
