Global health epidemics or pandemics have short and long-term negative psychological impacts, including anxiety, in people everywhere. We thus investigated the prevalence of COVID-19 anxiety among the general population aged ≥18 years. A web-based cross-sectional survey was conducted using a self-selected convenience sampling method among 546 participants. Participants completed a five-item Corona Virus Anxiety Scale, a measure of COVID-19 anxiety. We used SPSS software to perform descriptive and inferential analysis. The majority of the participants were
Abstract Astroblastoma is a rare central nervous system tumor. We reported a case of a 24‐year‐old Nepalese woman with radiological features mimicking pilocytic astrocytoma which came out to be low‐grade astroblastoma in histopathological and immunohistochemistry examination after total excision of the tumor.
Abstract Objectives Thyroid dysfunction carries large burden during pregnancy and untreated thyroid dysfunction is associated with poor maternal and foetal outcome. The exact burden of thyroid dysfunction during pregnancy in Nepal is not well established. This is descriptive cross‐sectional study done in tertiary care centre of Nepal to know burden of thyroid dysfunction and establish possible need of universal thyroid function screening during pregnancy. Methods A descriptive cross‐sectional study was conducted from 4 September 2020 to 3 September 2021 on pregnant women attending to ANC clinic during their first trimester after obtaining ethical approval. Among eligible patients, after taking informed consent, a total of 385 pregnant women were included in the study. Thyroid function status was assessed by measuring serum levels of thyroid stimulating hormone (TSH), free thyroxine (FT4), and free tri‐iodothyronine (FT3). Women with pre‐existing thyroid disorders were excluded. Serum thyroid function was used to detect thyroid disorder based on American Thyroid Association 2011 criteria. A convenience sampling method was used. Point estimate and 95% confidence interval (CI) were calculated. Results Among 385 pregnant women, 152 (39.48%) (39.20–39.70, 95% CI) had thyroid disorders. Among thyroid disorders ( n = 152), 111 (28.83%) had subclinical hypothyroidism, 37 (9.61%) overt hypothyroidism, 3 (0.78%) subclinical hyperthyroidism and 1 (0.26%) had overt hyperthyroidism. Conclusion Around four in every 10 pregnant women had thyroid disorder. Thyroid dysfunction is easily detectable and can be effectively, inexpensively treated, which can prevent adverse maternal and foetal outcome. Thus, we should consider universal screening of pregnant women for thyroid disorder especially in a country like Nepal where there is a high prevalence of undiagnosed thyroid disorder.
Abstract Heavy metal removal is critically necessary to prevent water pollution. At various initial hexavalent chromium concentrations, adsorbent dosages, pHs, and contact periods, the removal of hexavalent chromium from aqueous solutions onto Xanthated Tea Waste was investigated. FTIR and XRD techniques were used to characterize the adsorbent. Hexavalent chromium was initially removed from aqueous solutions with an increase in adsorbent dosage and contact time, but it was shown that the adsorption of Cr (VI) was best at a contact period of 120 min and an adsorbent dose of 100 mg/L. In a similar manner, the amount of hexavalent chromium eliminated from the aqueous solutions increased as the hexavalent chromium concentration grew and decreased as the solution's pH increased, with pH 2.0 being the ideal. Using a pseudo second-order model, the kinetics of hexavalent chromium adsorption onto modified tea trash was studied. The adsorption equilibrium data were modeled using Langmuir isotherm models. The equilibrium results for the elimination of hexavalent chromium by modified tea trash were well represented by the Langmuir isotherm model. According to the isotherm analysis, the adsorption equilibrium fit the Langmuir isotherm well. At pH 2.0, the obtained maximum adsorption capacity was around 82%. According to the findings, chromium-containing aqueous solutions can be treated using Xanthated Tea Waste as a low-cost adsorbent.
