Study finds significant portion of adult pneumonia hospitalizations linked to preventable pneumococcal infections

Although mRNA vaccines saved millions of lives during the COVID-19 pandemic, U.S. Health Secretary Robert F. Kennedy Jr. incorrectly argued they are ineffective to justify the Department of Health and Human Service's recent decision to cancel $500 million in government-funded research projects to develop new vaccines using the technology.

U.S. health regulators are warning doctors and patients about safety issues with two separate Boston Scientific heart devices recently linked to injuries and deaths.

Up to 60% of women experience some fear about giving birth, especially for the first time, but a new study shows why some women are more likely to stay calm and confident in the lead-up to childbirth.

Researchers at UC Santa Barbara have found that better access to technology can go a long way toward achieving equity in health care for African Americans in the United States.

While overdose deaths in the U.S. sharply declined in 2024, they remain high. Almost 90,000 Americans died from drug overdoses between October 2023 and September 2024. Overdose death rates are particularly high in American Indian and Alaska Native (AI/AN) people.

An analysis of over 36,000 people with high blood pressure has shown that taking more steps, even below the recommended daily target of 10,000 steps, and walking faster, is associated with a significant reduction in the risk of major problems of the heart and blood vessels.

In a study that tracked the diets of more than 205,000 adults over decades, French fries were associated with an increased risk of developing type 2 diabetes (T2D), while other forms of potatoes—including baked, boiled, and mashed—were not. The study, led by Harvard T.H. Chan School of Public Health also found that swapping any form of potato for whole grains may lower the risk of T2D.

Red blood cells, long thought to be passive bystanders in the formation of blood clots, actually play an active role in helping clots contract, according to a new study by researchers at the University of Pennsylvania.

Vaccination with the updated COVID-19 mRNA vaccine containing the severe acute respiratory syndrome coronavirus-2 omicron JN.1 lineage was not associated with an increased risk for 29 adverse events, according to a study published online July 28 in JAMA Network Open.

Women who experience complications during pregnancy, such as preeclampsia, preterm birth, gestational diabetes, miscarriage, or stillbirth, have an increased risk of ischemic stroke before the age of 50. This is the conclusion of recent research conducted by Radboud university medical center. While the study does not establish a causal relationship, it does highlight a clear association between these pregnancy complications and the risk of early stroke.

Oxygen deprivation around birth can lead to brain damage in babies, with far-reaching consequences. A new stem cell treatment administered via nasal drops is showing promising results.

For the first time, researchers from both Sheba Medical Center and Tel Aviv University have grown human kidney organoids (a synthetic 3D organ culture) from tissue stem cells in the laboratory, mirroring human fetal kidney development.

Immunotherapy uses the body's immune system to recognize and destroy cancer cells. One way to do this is through immune checkpoint inhibitors.

The toll of wildfires is usually counted in acres burnt, property destroyed and lives lost to smoke and flames. But three studies published Wednesday suggest the cost to human health from the Maui and Los Angeles wildfires was substantially higher.

A new study by UT Health San Antonio and Stanford University scientists brings us closer to understanding how the body detects different sensations such as pain, itch and touch.

Adverse drug reactions (ADRs) are a significant cause of hospital admissions and treatment discontinuation worldwide. Conventional approaches often fail to detect rare or delayed effects of medicinal products. In order to improve early detection, a research team from the Medical University of Sofia developed a deep learning model to predict the likelihood of ADRs based solely on a drug's chemical structure.

A study has identified a key disruption in cholesterol transport to the brain in patients with Alzheimer's disease. The findings suggest that the lipoproteins in the cerebrospinal fluid of patients with Alzheimer's have a reduced ability to deliver cholesterol to neurons, and that this impairment may be linked to the presence of the APOE4 genetic variant, one of the main known risk factors for the disease.

A new report from the Gerontological Society of America provides critical guidance for health care providers working with the nation's growing older adult population, highlighting strategies to improve communication, build trust, and support better health outcomes.
