SARS coronavirus 2 (SARS-CoV-2) isolates encoding a D614G mutation in the viral spike (S) protein predominate over time in locales where it is found, implying that this change enhances viral transmission. We therefore compared the functional properties of the S proteins with aspartic acid (SD614) and glycine (SG614) at residue 614. We observed that retroviruses pseudotyped with SG614 infect...
A tiny genetic mutation in the SARS coronavirus 2 variant circulating throughout Europe and the United States significantly increases the virus’ ability to infect cells, lab experiments performed at Scripps Research show.
Geriatrician Sharon Inouye on the need to combat delirium in COVID-19 patients
We report the neurologic features in an observational series of 58 of 64 consecutive patients admitted to the hospital because of acute respiratory distress syndrome (ARDS) due to Covid-19. The patients received similar evaluations by intensivists in two intensive care units (ICUs) in Strasbourg, France, between March 3 and April 3, 2020.
To a startling degree, many coronavirus patients are reporting similar experiences. Called hospital delirium, the phenomenon has previously been seen mostly in a subset of older patients, some of whom already had dementia, and in recent years, hospitals adopted measures to reduce it.
Delirium incidence, duration and severity in patients admitted to the intensive care unit (ICU) due to COVID-19 is not known.

CVD is a major burden on the health system in the UK. On average, diets are not aligned with current dietary recommendations, including those for salt, saturated fat, fibre, fruit and vegetables. Obesity prevalence is high and the majority of the population is consuming more energy than required. Addressing these issues would reduce the burden of CVD and help reduce inequalities in health. Ther...
As the biomedical community races to disentangle the unknowns associated with severe acute respiratory syndrome coronavirus 2, the virus responsible for causing coronavirus disease, the link between diminished immune function and individuals with obesity raises important questions about the possibility for greater viral pathogenicity in this population. Increased adiposity may undermine the pul...
Physical activity (PA) has strong relevance for limiting the harms to human health and well-being due to the COVID-19 pandemic.1 Active muscles produce chemicals that improve immune functioning, which in turn reduces the extent of infections, and decreases inflammation, and these are the main causes of the lung damage from SARS-CoV-2 infection. PA is a powerful preventive and therapeutic interv...
The SARS-CoV-2-caused COVID-19 pandemic has resulted in a devastating threat to human society in terms of health, economy, and lifestyle.
