RESUMEN
Background: The Indian population is suffering from a high prevalence of mental stress and the situation has been worsened by the COVID-19 pandemic. Mindfulness, which can also be conducted online, has been used as a stress-relieving therapy in the Western world. There is not much experience with mindfulness in the Indian population. The COVID-19 pandemic demands the development of alternative therapies which can reach out to the masses at a minimal cost, avoiding direct personal contact. The researchers wanted to explore the potential of mindfulness as a stress-relieving therapy. Aim: To note any improvement in perceived stress of the participants compared to the controls. Methods: Ninety apparently healthy adults were randomized into group M (all of whom participated in an online mindfulness program) and group C (all of whom attended placebo sessions), with 45 participants each. Final sample size was n = 42 (group M) and n = 38 (group C). The perceived stress was measured using the perceived stress scale before and after the program. Qualitative data was collected in the form of written responses to the question "Which aspect of mindfulness meditation appealed to you the most for stress relief?" and some themes were formed. Results: There was a significant decrease in perceived stress scale scores on completion of the program in group M. "Positive mental state" and "non-judgmental" were the most prominent emergent themes suggested by the participants, as per the qualitative data analysis. Conclusion: This preliminary study sees potential in an online mindfulness program as an alternative stress-relieving therapy. Further research is suggested to substantiate the results and optimize the implementation.
RESUMEN
UNLABELLED: The objective of the present study ( clinicaltrials.gov NCT02026414) was to observe the effects of oral supplementation of a purified and standardized Shilajit extract on skeletal muscle adaptation in adult overweight/class I obese human subjects from the U.S. POPULATION: Shilajit is a mineral pitch that oozes out of Himalayan rocks. The study design consisted of a baseline visit, followed by 8 weeks of 250 mg of oral Shilajit supplementation b.i.d., and additional 4 weeks of supplementation with exercise. At each visit, blood samples and muscle biopsies were collected for further analysis. Supplementation was well tolerated without any changes in blood glucose levels and lipid profile after 8 weeks of oral supplementation and the additional 4 weeks of oral supplementation with exercise. In addition, no changes were noted in creatine kinase and serum myoglobin levels after 8 weeks of oral supplementation and the additional 4 weeks of supplementation with exercise. Microarray analysis identified a cluster of 17 extracellular matrix (ECM)-related probe sets that were significantly upregulated in muscles following 8 weeks of oral supplementation compared with the expression at the baseline visit. This cluster included tenascin XB, decorin, myoferlin, collagen, elastin, fibrillin 1, and fibronectin 1. The differential expression of these genes was confirmed using quantitative real-time polymerase chain reaction (RT-PCR). The study provided maiden evidence that oral Shilajit supplementation in adult overweight/class I obese human subjects promoted skeletal muscle adaptation through upregulation of ECM-related genes that control muscle mechanotransduction properties, elasticity, repair, and regeneration.
