Background: Coronavirus disease is an emerging pandemic disease. The whole world is suffering from this disease these days. It is an acute respiratory disease in which transmission occurs essentially through respiratory droplets and this virus said to have 2-14 days of incubation.Objective: To assess their knowledge regarding COVID19 among registered nurses of Pokhara valley.Methods: A descriptive cross-sectional study was performed with the help of the pretested and self-administered questionnaires to 750 registered nurses of Pokhara valley. Thus collected data was entered into SPSS version 20 and then further analyzed using R software. Frequency, percentages, the mean and standard deviation were calculated for the analysis. p-value was calculated where ever applicable to find the significance of data.Results: The study disclosed that mass of the respondents had moderate proportion (44.8%) concerning understanding, followed by the respondents had a low level of knowledge (29.2%) and the rest of them (26.0%) had good knowledge about COVID 19.Conclusion: Overall knowledge among nurses was found to be satisfactory as the disease is entirely new. Further research and updates on the diseases will help to profound knowledge among nurses.

Obesity has recently emerged as one of the most severe health concerns. Obesity is a key autonomous risk factor for heart failure and contributes to cardiovascular disease (CVD) risk factors such as hypertension, type 2 diabetes, and metabolic abnormalities. Obesity is caused by a metabolic imbalance, which occurs when calories burnt are fewer than the number of calories consumed. There are several pathways accountable for the adverse impacts of obesity on the cardiovascular system. Inflammatory cell infiltration develops in the adipose tissue, the pancreas, and other issues similar to the progression of obesity. Inflammation is triggered by immune cells that invade dysfunctional adipose tissue. The atherosclerotic inflammation phase, related to obesity, induces coronary calcification. Obesity is linked to elevated levels of leptin and high blood pressure. Leptin causes systemic vasoconstriction, sodium retention, and increased blood pressure by influencing the synthesis of nitric oxide and activating the sympathetic nervous system. Obesity is a well-known risk factor for CVD and is one of the leading causes of the greater risk of diseases, including dyslipidemia, hypertension, depression, metabolic syndrome, atrial fibrillation, and heart failure in adults and children.When used with dietary improvements, antiobesity drugs improve the probability of experiencing clinically healthy (5%) weight loss. This review aimed to address the consequences of obesity on cardiac structure and function, risk factors, the impact of the obesity paradox, pharmacological treatment strategies for managing and recommended exercise and diet.

In the account of the social nature of human beings, the given difficult circumstance due to COVID-19 may call upon social loneliness, emotional loneliness, and moreover, lack of perceived social support. We aim to elucidate by assessing the level of loneliness and the level of social support perceived by college students amidst the COVID-19 lockdown. A web-based cross-sectional survey was conducted among 970 Nepalese undergraduate students. Responses were extracted, cleaned, and analyzed with the help of R-studio (version 1.2.5033). Descriptive statistics such as frequency, percentage, mean and standard deviation described participants’ demographic characteristics. Karl Pearson’s Correlation analysis and significant test of correlation for loneliness, social support, and their various subscales, respectively were significant at 0.1%, 1%, and 5% level of significance. The mean age of respondents was 22.2 years (SD =2.74). Significant correlations were observed among social loneliness, emotional loneliness, overall loneliness (social loneliness and emotional loneliness combined), social family support, social friends support, social significant others support, and total social support (that is to say, all the social support subscales). The study reported that a decrease in social support leads to an increase in loneliness. Likewise, a decrease in social support from family, friends, and from significant others can increase emotional and overall loneliness.
