SARS-CoV-2-RNA viremia is a robust marker of critical illness in COVID-19

A new study by a large team of Spanish researchers and published on the preprint server medRxiv* in August 2020 reports that the presence of viral RNA in the blood is a useful marker of impending acute disease and can help triage COVID-19 disease patients who will require hospital care.

Negligible ACE2 expression in human beta-cells

Now, a new study published on the preprint server bioRxiv reports that even though the fatality rate is significantly higher in diabetics, there is no evidence that this is due to direct viral infection of pancreatic beta cells, which produce the key hormone in glucose homeostasis, namely insulin.

Growth hormone associated with early puberty and future breast cancer risk

When girls reach puberty at an unusually early age, they face a significantly higher risk of developing breast cancer later in life. Now, experts at Cincinnati Children's and the University of Cincinnati offer a new, unified explanation for why that increased risk occurs.

Surgeons use patients' own stem cells to rebuild damaged corneas

Surgeons at Massachusetts Eye and Ear have replaced the ocular surface of four patients who each experienced chemical burns to one eye by using their own stem cells taken from the other healthy eye, in a technique known as "cultivated autologous limbal epithelial cell transplantation" (CALEC).

Low dose colchicine significantly reduces risk of cardiovascular death

An Australian-Dutch trial led by Perth GenesisCare cardiologists, Professor Peter Thompson and Dr Mark Nidorf, in collaboration with the Dutch Network for Cardiovascular Research (WCN) in the Netherlands, confirmed that low dose colchicine was safe, well-tolerated over the long-term, and significantly reduced the risk of cardiovascular death, heart attack, and ischemic stroke in patients with chronic coronary disease.

Diminished biological arousal before global pandemic may predict PTSD symptoms

People who did not have a large heart rate response to a stress task surprised researchers later -- after the onset of the COVID-19 pandemic -- when they showed more symptoms of post-traumatic stress disorder related to the crisis than others who also did the stress task and COVID-19 stress ratings.

Study: Impact of COVID-19 virus goes far beyond the pulmonary system

Described as a novel, "once-in-a-century" disease, COVID-19 research is evolving to include a growing body of evidence that the virus's impact goes far beyond the pulmonary system.
