How SARS-CoV-2 contributes to heart attacks and strokes
COVID-19 is known to increase the risk of heart attack and stroke. The intense inflammation that occurs throughout the body in severe cases likely contributes to this increased risk. But it’s not clear whether SARS-CoV-2, the virus that causes COVID-19, also affects blood vessels directly.
To find out, an NIH-funded research team, led by Dr. Chiara Giannarelli at New York University School of Medicine, analyzed coronary artery tissue samples from eight people who died of COVID-19 between May 2020 and May 2021. Results appeared in Nature Cardiovascular Research on September 28, 2023.

Researchers estimate 1% or 2% of hospital patients in England caught COVID after admission
During the country’s second COVID wave, 95,000 to 167,000 hospital patients in England were infected with SARS-CoV-2 in the hospital, partly due to a lack of single rooms, suggests a study published yesterday in Nature.

COVID can worsen lower urinary tract symptoms in men
Research in the Journal of Internal Medicine indicates that SARS-CoV-2 infections may worsen lower urinary tract symptoms (LUTS) in men, based on 18,000 men treated for LUTS in Hong Kong in 2021 and 2022.

This MacArthur ‘genius’ knew the initial theory of COVID transmission was flawed
The groundbreaking research of Linsey Marr, an aerosols expert and professor of civil and environmental engineering at Virginia Tech, showed that the SARS-CoV-2 virus is airborne as opposed to traveling in large droplets that fall with gravity.

Scientists behind mRNA COVID Vaccines Win 2023 Nobel Prize in Physiology or Medicine
This year’s Nobel Prize in Physiology or Medicine goes to a transformative medical technology that significantly altered the path of the pandemic and saved millions: the mRNA vaccines against COVID. Katalin Karikó and Drew Weissman were jointly awarded the prize for advancements that have changed the field of vaccine development and researchers’ understanding of how messenger RNA (mRNA) interacts with the body’s immune system.

SARS-CoV-2 can infect coronary arteries and trigger heart attack, stroke, study suggests
SARS-CoV-2 can directly infect the arteries of the heart, inflaming the fatty plaque inside and raising the risk of heart attack and stroke, suggests a small study published yesterday in Nature Cardiovascular Research.

SARS-CoV-2 infects coronary arteries, increases plaque inflammation
SARS-CoV-2, the virus that causes COVID-19, can directly infect the arteries of the heart and cause the fatty plaque inside arteries to become highly inflamed, increasing the risk of heart attack and stroke, according to a study funded by the National Institutes of Health. The findings, published in the journal Nature Cardiovascular Research, may help explain why certain people who get COVID-19 have a greater chance of developing cardiovascular disease, or if they already have it, develop more heart-related complications.

People with Long COVID Have Distinct Hormonal and Immune Differences From Those Without This Condition
Long COVID patients have clear differences in immune and hormone function from patients without the condition, according to a new study led by the Icahn School of Medicine at Mount Sinai and Yale School of Medicine.
The research, published in the September 25 issue of Nature, is the first to show specific blood biomarkers that can accurately identify patients with long COVID.
