TUESDAY, Nov. 1, 2022 (American Heart Association News) -- A third dose of the Moderna or Pfizer COVID-19 vaccine poses no more risk of heart inflammation than a second dose, a large study suggests. The findings could help allay concerns about risk going up with each additional dose.Cases were rare. Most appeared within seven days of vaccination and the patients recovered, found the study, which is being presented Saturday at the American Heart Association's Scientific Sessions. The work is considered preliminary until full results are published in a peer-reviewed journal.Researchers examined the health records of millions of Southern Californians to see whether third doses of the vaccines, which use mRNA technology to activate the body's defenses against the coronavirus, were linked...

TUESDAY, Nov. 1, 2022 (HealthDay News) -- Discrimination doesn’t just cause emotional pain in the moment, it may affect a victim's physical recovery from a heart attack, new research suggests.In studying more than 2,600 heart attack survivors between the ages of 18 and 55, researchers found that those reporting more perceived discrimination were more likely to have poorer outcomes.A year after their heart attacks, they had more physical limitations and chest pain, lower quality of life and impaired mental health.Perceived discrimination — being treated unfairly because of personal characteristics such as race, gender or sexual orientation — was already associated with risk factors for having a heart attack.Discrimination is a chronic stressor, said study author Andrew Arakaki, a...

An unhealthy gut leaves a person vulnerable to life-threatening diarrhea from harmful...

TUESDAY, Nov. 1, 2022 (HealthDay News) -- Women who have autism are more vulnerable during pregnancy to depression and anxiety, according to a new British study.That makes it imperative that effective mental health screening and support is available to help this group, said lead researcher Sarah Hampton, from the University of Cambridge."The results also suggest that autistic people may benefit from accommodations to prenatal health care. These may include adjustments to the sensory environment of health care settings, as well as adjustments to how information is communicated during prenatal appointments," co-author Rosie Holt said in a university news release. She is a research associate at the Cambridge-based Autism Research Center.For their study, researchers surveyed more than 900...
