by University College London Credit: Pixabay/CC0 Public Domain The damage caused by COVID-19 to the lungs’ smallest blood vessels has been intricately captured using high-energy X-rays emitted by a special type of particle accelerator. Scientists from UCL and the European Synchrotron Research Facility (ESRF) used a new revolutionary imaging technology called Hierarchical Phase-Contrast Tomography (HiP-CT),...
by McGill University Health Centre Credit: Pixabay/CC0 Public Domain Despite high hopes, a new pan-Canadian study published today in The BMJ suggests that ciclesonide—an inhaled and nasal steroid drug commonly used for asthma and rhinitis—won’t be the treatment to change the course of the pandemic. The results of this first placebo controlled trial of inhaled steroids for...
NOVEMBER 2ND, 2021, CONN HASTINGS Researchers at Ohio State University managed to develop a breath test for COVID-19 that can spot the infection within seconds. The basis for the test is a unique ‘breath print’ of COVID-19 that the researchers have identified, and this includes a specific combination of oxygen, nitric oxide, and ammonia in...
by Ludwig Maximilian University of Munich Dendritic cell. Credit: D. Dudziak COVID-19 reduces the numbers and functional competence of certain types of immune cells in the blood, say LMU researchers. This could affect responses to secondary infections. The SARS-CoV-2 coronavirus causes moderate to severe disease in 3–10% of those infected. In such cases, the immune system...
by Johns Hopkins University School of Medicine A Johns Hopkins Medicine study of nearly 4,500 patients hospitalized with COVID-19 suggests that statins — medications widely used to control cholesterol — are not helpful in reducing COVID-related mortality or the severity of the illness.

The JAMA Network Open study of employee vaccinations within the Mass General Brigham health care system revealed that although people with such a history reported...
Megan Brooks Editor’s note: Find the latest COVID-19 news and guidance in Medscape’s Coronavirus Resource Center. Risk for Alzheimer’s disease (AD) and susceptibility to severe COVID-19 share a common genetic mechanism involved in the immune response to viruses, investigators report. The findings could lead to new treatment targets to slow progression and severity of both diseases. Investigators found...
by George Institute for Global Health Distributions of the Primary Outcome and Time to Death Curves to Day 90 A, Life support was defined as invasive mechanical ventilation, circulatory support, or kidney replacement therapy. There were missing data in 11 patients for the primary outcome. Red represents the worse outcomes and blue represents better outcomes. B,...

by Barcelona Institute for Global Health Credit: Unsplash/CC0 Public Domain A new study led by the Barcelona Institute for Global Health (ISGlobal) provides robust evidence that COVID-19 is a seasonal infection linked to low temperatures and humidity, much like seasonal influenza. The results, published in Nature Computational Science, also support the considerable contribution of airborne SARS-CoV-2 transmission...
