Even mild cases of COVID-19 are associated with brain changes including decreased gray matter, an overall reduction in brain volume, and cognitive decline, a new imaging study shows. In the first study to use magnetic resonance brain imaging, before and after COVID-19, investigators found “greater reduction in grey matter thickness […]
Purpose:We assessed long‑term outcomes of dexamethasone 12 mg versus 6 mg given daily for up to 10 days in patients with coronavirus disease 2019 (COVID‑19) and severe hypoxaemia.Methods:We assessed 180‑day mortality and health‑related quality of life (HRQoL) using EuroQoL (EQ)‑5D‑5L index values and EQ visual analogue scale (VAS) in the […]
As top U.S. health officials track the latest COVID-19 spike in Europe, they’re encouraging Americans not to panic about another potential wave hitting the country. “Our focus should be on preparation, not on panic,” Vivek Murthy, MD, the U.S. surgeon general, said on Fox News Sunday. BA.2, the Omicron subvariant, has […]
A key part of the immune system’s second-line defense – its T cells – are highly effective at recognizing and attacking the Omicron variant, a new study shows. Omicron’s mutations help it escape from antibodies, but researchers have speculated that other components of the immune response would still target Omicron. […]
COVID-19 patients who are successfully weaned off a ventilator may take days, or even weeks, to regain consciousness, especially those who experienced episodes of hypoxemia while intubated, a new study shows. “As we started to see the first patients waking up after successful COVID-19 ICU treatments, we also encountered many […]
Before March 2020, many people saw pandemics as a thing of the past. Then came COVID-19. Scientists still do not know exactly where the virus that caused it — SARS-CoV-2 — came from, but it soon reached almost every country worldwide. Over 2 years, the virus has evolved, producing several […]
The comparatively milder infections with the Omicron variant and higher levels of population immunity have raised hopes for a weakening of the pandemic. We argue that the lower severity of Omicron is a coincidence and that ongoing rapid antigenic evolution is likely to produce new variants that may escape immunity […]
All pandemics end eventually. But how, exactly, will we know when the COVID-19 pandemic is really “over”? It turns out the answer to that question may lie more in sociology than epidemiology. As the world passes the second anniversary of the World Health Organization’s declaration of the COVID pandemic, things seem […]

It’s now known that tinnitus may be an unexpected side effect of SARS-CoV-2 vaccination, and there is an urgent need to understand the precise mechanisms and best treatment for vaccine-associated tinnitus, researchers say. As of mid-September 2021, 12,247 cases of tinnitus, or ringing in the ears, following COVID-19 vaccination have been reported […]
