SARS-CoV-2 was first detected in 2019 in Wuhan, China. It has been found to be the most pathogenic virus among coronaviruses and is associated with endothelial damage resulting in respiratory failure. Determine whether heparanase and heparan sulfate fragments, biomarkers of endothelial function, can assist in the risk stratification and clinical management of critically ill COVID-19 patients admitted to the intensive care unit. We investigated 53 critically ill patients with severe COVID-19 admitted between March and April 2020 to the University Hospital RWTH Aachen. Heparanase activity and serum levels of both heparanase and heparan sulfate were measured on day one (day of diagnosis) and day three in patients with COVID-19. The patients were classified into four groups according to the severity of ARDS. When compared to baseline data (day one), heparanase activity increased and the heparan sulfate serum levels decreased with increasing severity of ARDS. The heparanase activity significantly correlated with the lactate concentration on day one (r = 0.34, p = 0.024) and on day three (r = 0.43, p = 0.006). Heparanase activity and heparan sulfate levels correlate with COVID-19 disease severity and outcome. Both biomarkers might be helpful in predicting clinical course and outcomes in COVID-19 patients.

OBJECTIVES: Assess well-being among older adults through secondary analysis measured during an annual survey in 2018, 2019, and 2020, to determine trends from before and during the COVID-19 pandemic. METHODS: Mailed surveys sent annually included measures related to various psychosocial factors. MAIN FINDINGS: Response rates were 29% in 2018, 25% in 2019, and 24% in 2020. Most respondents reported average or high resilience (89% 2018-2020), high purpose (64% in 2018 and 2019, 63% in 2020), moderate optimism (46% in 2019, 44% in 2020) and low stress (88% in 2019 and 2020). Reported loneliness increased 13% from 2018 to 2020. In 2020, only 45% reported high comfort with technology, decreasing with age (>75). PRINCIPAL CONCLUSION: Psychosocial well-being of respondents were doing well despite changes related to COVID-19. However, increased loneliness may negatively impact long-term health outcomes; thus, a focus on technology options to stay socially connected and access healthcare are needed.

Risk of COVID-19 exposure and more severe illness are serious concerns for older adults. Social distancing has worsened existing social isolation, with severe impacts on connectedness among seniors. The pandemic is threatening to cause an extended health crisis, with impacts including serious health consequences. Our primary purpose is to summarize emerging research describing the impacts of the pandemic on social isolation among older adults. A streamlined search was conducted to fit the scope of this literature review. Common research databases and mainstream resources and websites were utilized to identify research published or released in 2020 to align with the pandemic. Early research indicates that the pandemic has worsened social isolation among older adults. Social isolation has become urgent, as seniors have lost their usual connections due to social distancing. While safety measures are critical to prevent virus exposure, this approach must be balanced with maintaining social connectedness. The pandemic highlights the importance of social connections, with significant impacts on both community-living older adults and those in nursing facilities. Safety protocols have created a paradox of reduced risk along with greater harm. Consequently, adapted approaches are urgently needed to address the consequences of a long-term social recession.
