Researchers found that one in three men had minimal symptomatic benefits from tamsulosin, the most commonly prescribed medication for older men with a form of urinary tract infections, and suggest that they should be deprescribed of this medication.
UCSF researchers are using tiny "mini-organs" to model disease, personalize treatment, and understand human development. They are also addressing the limitations holding the field back: giving organoids a vascular system and making organoids reproducible.

UCSF scientists discovered that a small change to a SARS-CoV-2 protein dictates whether the virus lives quietly in bats or causes disease in people. Understanding these changes could help scientists predict or prevent future pandemics.
Congenital heart disease is a condition primarily associated with infants and children, but that is changing. More adults than children now live with congenital heart disease (ACHD) in the U.S., an

A new UCSF study looks at the real reasons women with HIV are dying earlier than people without HIV, and finds these leading causes are largely missing from official death records.
A UCSF team developed an automated system for seeing and understanding persister cells, the tumor cells that survive cancer treatment and regrow tumors.
Ethan Winkler, who studies aneurysms, discovered a dynamic between cells in the brain's blood vessels that explains why aneurysms burst. The findings describe a "life cycle" of an aneurysm and will likely change how physicians assess the risk for rupture and opportunities for personalizing treatment.
A new study of more than 16,000 people who sought help from a nationwide abortion and miscarriage hotline found demand for confidential clinical support surged both before and after the U.S. Supreme Court decision that overturned federal abortion protections.
A study looked at how ultraprocessed foods (UPFs), like Lunchables, are designed—and why they may lead to overeating and weight gain. Using internal company documents, the study showed that Lunchables were influenced by strategies from the tobacco industry, specifically Philip Morris, which once owned Kraft.
