Researchers find a higher than expected risk of myocarditis in young men after full vaccination.

Males between 16 and 29 years of age have an increased risk of developing heart problems after receiving a second dose of coronavirus vaccines made by Pfizer-BioNtech or Moderna, according to a large new analysis published on Wednesday in the New England Journal of Medicine. The study, conducted in Israel, estimated that nearly 11 of every 100,000 males in that […]

Researchers link PTSD, anxiety fears in women with history of military sexual trauma

A new Veterans Affairs study finds a strong link between PTSD symptom severity and anxiety sensitivity among female Veterans who have experienced military sexual trauma. The researchers say treating the anxiety problem may be a way to ease core PTSD symptoms. Anxiety sensitivity reflects a fear of physical sensations that accompany anxiety. A person with high levels of anxiety sensitivity […]

Researchers pinpoint how PARP inhibitors combat BRCA1 and BRCA2 tumor cells

A team of Massachusetts General Hospital (MGH) researchers has discovered how an important class of anti-cancer drugs called PARP inhibitors works, a finding that could help improve treatment and prolong survival for patients with breast cancer and other malignancies. PARP (poly[ADP-ribose] polymerase) inhibitors such as olaparib (Lynparza), rucaparib (Rubraca) and niraparib (Zejula) are used to treat patients with cancers of […]

Researchers propose strategies to speed global vaccine availability

In a new paper published in the journal Vaccine: X, public health experts from Columbia University Mailman School of Public Health, the University of Oslo, and Spark Street Advisors highlight actions to accelerate access to vaccines globally. The paper reviews the vaccine research and development process and proposes areas where reforms could increase access, speed time to market and decrease […]

Researchers uncover mechanism related to severe post-COVID-19 disease in children

A multidisciplinary team from MassGeneral Hospital for Children (MGHfC), Brigham and Women’s Hospital and other institutions have identified the mechanism of how an extremely rare but serious post-COVID-19 complication develops in children and adolescents. Led by MGHfC pediatric pulmonologist Lael Yonker, MD, researchers determined that viral particles remaining in the gut long after an initial COVID-19 infection can travel into […]

Researchers identify novel approach to repair the human heart

A team of scientists from Loyola University Chicago’s Stritch School of Medicine have discovered a critical component for renewing the heart’s molecular motor, which breaks down in heart failure. Approximately 6.2 million Americans have heart failure, an often fatal condition characterized by the heart’s inability to pump enough blood and oxygen throughout the body. This discovery could represent a novel […]

Researchers report COVID-19 found in penile tissue could contribute to ED

University of Miami Miller School of Medicine researchers are the first to demonstrate that COVID-19 can be present in the penis tissue long after men recover from the virus. The widespread blood vessel dysfunction, or endothelial dysfunction, that results from the COVID-19 infection could then contribute to erectile dysfunction, or ED, according to the study recently published in the World […]

Researchers discover regulatory pathway that blocks immune response against cancer

A hallmark of cancer is its ability to evade the immune system. It is why researchers are focused on finding new strategies and targets to jumpstart the immune system so it can mount a response against tumors. One such target is the inhibitory receptor T-cell immunoglobulin and mucin domain 3 (TIM-3), a protein that is overexpressed in many different types […]

Researchers map how people in cities get a health boost from nature

Your local city park may be improving your health, according to a new paper led by Stanford University researchers. The research, published in Proceedings of the National Academy of Sciences, lays out how access to nature increases people’s physical activity—and therefore overall health—in cities. Lack of physical activity in the U.S. results in $117 billion a year in related health […]

Researchers develop mathematical model predicting disease spread patterns

Early on in the COVID-19 pandemic, health officials seized on contact tracing as the most effective way to anticipate the virus’s migration from the initial, densely populated hot spots and try to curb its spread. Months later, infections were nonetheless recorded in similar patterns in nearly every region of the country, both urban and rural. A team of environmental engineers, […]
