New research at Washington University School of Medicine in St. Louis indicates that three new, fast-spreading variants of the virus that cause COVID-19 can evade antibodies that work against the original form of the virus that sparked the pandemic. With few exceptions, whether such antibodies were produced in response to vaccination or natural infection, or […]
People who took statins to lower cholesterol were approximately 50% less likely to die if hospitalized for COVID-19. Study analyzed data from electronic health records Based on their observations, the authors looked at outcomes for 2,626 patients with COVID-19 who were admitted to a quaternary academic medical center in Manhattan during the first 18 weeks […]
Higher consumption of fruits and vegetables is associated with a lower risk of death in men and women, according to data representing nearly 2 million adults. Five daily servings of fruits and vegetables, eaten as 2 servings of fruit and 3 servings of vegetables, may be the optimal amount and combination for a longer life. […]
Study reveals details of how coronavirus infects heart; models of tissue damage may help develop potential therapies. Since early in the pandemic, COVID-19 has been associated with heart problems, including reduced ability to pump blood and abnormal heart rhythms. But it’s been an open question whether these problems are caused by the virus infecting the […]
Almost one in five people lacks the protein α-actinin-3 in their muscle fibre. Researchers at Karolinska Institutet now show that more of the skeletal muscle of these individuals comprises slow-twitch muscle fibres, which are more durable and energy-efficient and provide better tolerance to low temperatures than fast-twitch muscle fibres. The results are published in The […]
Challenging the idea that older people with shorter life expectancies should rank lower in coronavirus immunization efforts, new UC Berkeley research shows that giving vaccine priority to those most at risk of dying from COVID-19 will save the maximum number of lives, and their potential or future years of life. Since older age is accompanied […]
People with periodontitis are at higher risk of experiencing major cardiovascular events, according to new research from Forsyth Institute and Harvard University scientists and colleagues. For the study, researchers performed positron emission tomography and computer tomography (PET and CT) scans on 304 individuals to view and quantify inflammation in the arteries and gums of each […]
Antibodies that guard against COVID-19 can transfer from mothers to babies while in the womb, according to a new study from Weill Cornell Medicine and NewYork-Presbyterian researchers published in the American Journal of Obstetrics and Gynecology. Pregnant women who generate protective antibodies after contracting the coronavirus often convey some of that natural immunity to their […]
Children exposed to air pollution, such as wildfire smoke and car exhaust, for as little as one day may be doomed to higher rates of heart disease and other ailments in adulthood, according to a new Stanford-led study(link is external). The analysis, published in Nature Scientific Reports , is the first of its kind to […]
Seasons have an impact on our emotions and social life. Negative emotions are more subdued in the summer, whereas seasonal affective disorder rates peak during the darker winter months. Opioids regulate both mood and sociability in the brain. In the study conducted at the Turku PET Centre, Finland, researchers compared how the length of daylight […]
