Angiotensin-converting enzyme 2 (ACE2) is a key host protein by which severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) enters and multiplies within cells. The level of ACE2 expression in the lung is hypothesised to correlate with an increased risk of severe infection and complications in COVID-19 (COrona VIrus Disease 2019). To test this hypothesis, we compared the protein expression status of ACE2 by immunohistochemistry (IHC) in post-mortem lung samples of patients who died of severe COVID-19 and lung samples obtained from non-COVID-9 patients for other indications. IHC for CD61 and CD163 were performed for assessment of platelet-rich microthrombi and macrophages, respectively. IHC for SARS-CoV-2 viral antigen was also performed. Quantification of immunostaining, random sampling, and correlation analysis was used to substantiate the morphologic findings. Our results show that among a total of 44 COVID-19 post-mortem lung tissues and 15 lung biopsies in non-COVID-19 patients included, ACE2 protein expression was significantly higher in COVID-19 patients than in controls, regardless of sample size. Histomorphology in COVID-19 lungs showed diffuse alveolar damage (DAD), acute bronchopneumonia, and acute lung injury with SARS-CoV-2 viral protein detected in a subset of cases. ACE2 expression levels positively correlated with increased expression levels of CD61 and CD163. In conclusion, our results show significantly higher ACE2 protein expression in severe COVID-19 disease, correlating with increased macrophage infiltration and microthrombi, suggesting a pathobiological role in disease severity.

Background: The COVID-19 pandemic led lockdown-an unprecedented event wherein people globally have been hit hard. This lockdown has caused a deep impact on lifestyle-related parameters like sleep pattern, diet pattern, stress level, physical activity level and circadian rhythms. Objective: This study was designed to study effect of COVID-19 pandemic on lifestyle of young adults and adolescents. Method: Online survey was conducted in 1065 respondents in the age group of 13 to 25 years. Result: Questionnaire-based survey showed mean sleep duration changing from 6.85 hours to 8.17 hours, average screen time increased to 5.12 hours from 3.5 hours, 51.9% subjects experienced higher stress levels, 76.4% subjects experienced more food intake and 38.6% subjects had decreased levels of physical activity as per self-monitoring. Conclusion: These changes might have long lasting effects on their physical, mental and social health and need counteractive measures to help young people lead a healthy lifestyle during the epidemic and beyond.

BACKGROUND The corona virus disease 2019(COVID-19) is caused by the virus SARS-CoV-2 and is declared as a global pandemic by World Health Organization (WHO). Various hematological parameters alteration has been documented in the Chinese literature in SARS-Cov-2 infection. However, there is a need for research to evaluate the pattern of the hematological parameters of COVID-19 patients in the Indian population. OBJECTIVE The objective of the study is to see the Neutrophil-Lymphocyte Ratio (NLR), Platelet Lymphocyte Ratio (PLR), and other hematological parameters alteration of COVID-19 patients along with their clinical course in the Indian scenario. METHODS A single-center prospective study of 32 patients with laboratory-confirmed COVID-19 admitted to Super Speciality Pediatric Hospital & Post Graduate Teaching Institute NOIDA, from March to April, were enrolled for the study. The demographic date, the clinical status of the patients during admission and follow up, baseline, and follow up hematological findings were recorded. Statistical analysis of the data was carried out, and relevant findings were presented. RESULTS Demographic characterization shows a mean age of 37.7 years, male (41.9%),female (58.1%)with majority patients are mildly symptomatic to asymptomatic(93%). The CBC values and NLR, PLR at baseline between the male and the female patients, are not showing any statistically significant difference as the 95% C.I. A statistically significant increment in the lab parameters is observed in follow-up visits. CONCLUSIONS Majority of the patients are younger and have mild clinical presentation with female predominance. Pediatric cases have mild symptomology. Baseline CBC findings show mild neutrophilia, lymphopenia, eosinopenia and normal to mild thrombocytopenia. An increase in CBC parameters, NLR was noted in follow up cases. Anemia was not noted in baseline CBC andin follow up group. A onetime PLR is not indicative of disease progression. CLINICALTRIAL NA
