ABSTRACT
BACKGROUND The Covid-19 pandemic caused a rapidly evolving and confused situation. Health sciences students (HSSs) are not immune to depression, anxiety and stress during such a pandemic. We aimed to assess the relation between depression, anxiety, stress and resilience among undergraduate HSSs during the Covid-19 lockdown. METHODS We conducted a cross-sectional, online survey at a rural tertiary healthcare centre in Maharashtra. Data were recorded from study participants on sociodemographic details using the 21-item Depression, Anxiety and Stress Scale (DASS-21) and the Brief Resilience Scale (BRS). Data were analysed using SPSS software version 15.0. RESULTS A total of 381 students participated in the online survey. The prevalence of depression, anxiety and stress were 7.6%, 6.3% and 1.0%, respectively. There was a positive correlation between all three sub-scales of DASS-21. On BRS, 5 (1.3%) participants had high resilience, 216 (56.7%) had normal resilience and 160 (42.0%) had low resilience. Those respondents who had high resilience had lower rates of depression, anxiety and stress on DASS-21 sub-scales. CONCLUSION A proportion of HSSs had anxiety, depression and stress during the Covid-19 outbreak and lockdown. Respondents with high resilience had less frequent depression, anxiety and stress. In the long run, strengthening resilience of HSSs may be useful.
ABSTRACT
Gastric carcinoma is the fourth most common cancer type and the second leading cause of cancer deaths worldwide. Every year, around 1 million new cases and 0.7 million deaths are caused due to gastric carcinoma. Gastrointestinal tract is involved in absorption and metabolism of toxic or potentially carcinogenic compounds which may be present in the food we eat. In this context, digestive tract may be considered as a major site of cancer in humans. Glutathione-S-Transferase (GST) is an important metabolizing enzyme, present in the epithelial cells of human GIT. As nearly all reactive, ultimate carcinogenic forms of chemicals are electrophiles, GST is substantially important as a mechanism for carcinogen detoxification. The present study was conducted to evaluate the role of GST in gastric carcinoma and analyse the level of serum GST in patients suffering from gastric carcinoma. METHODSThis is a case control study, conducted among 50 cases of gastric carcinoma and 50 age sex matched controls. Patients included in this study were diagnosed with gastric carcinoma, after clinical and histological examination. Circulating levels of GST were assayed in the in the serum of control group and in patients with gastric carcinoma, using standardized method. RESULTSMean GST activity in serum was significantly higher (p < 0001) in gastric carcinoma patients (8.24 ± 1.94) as compared to control (5.47 ± 0.52). After chemotherapy (12.34 ± 1.05) the activity of GST was significantly higher (p < 0001) than before chemotherapy (10.23 ± 2.12). The generation of free radicals is as reflected by increased GST and GST-π activity in carcinoma cases. CONCLUSIONSSerum GSTs measurement in plasma may be a useful tumour marker in stomach cancer and serum GSTs activity might be helpful in predicting the response of chemotherapy in advanced stages of cancer. GST values are helpful in predicting the radiation response. Overexpression of GST in neoplasia may be causal, allowing replicative advantage, or casual, accompanying clonal expansion. The major limitation to its widespread use is the time needed for doing the assay and until this is overcome it will remain primarily a research tool.
