The American Cancer Society now recommends clearer PSA screening schedules, with earlier annual testing for Black men and certain men with a family history, following stronger evidence that screening can reduce prostate cancer deaths.
A boy, 15, needed emergency treatment after drinking a beverage containing cod collagen, even though skin prick tests for several fish allergies were negative. Experts say fish derived proteins in drinks and supplements demand close label scrutiny.
Sunharbo reduced ischemic stroke risk by 26% in a phase 3 trial, but bleeding concerns affected some patients. Cardiologist Richard Kovacs says treatment discussions should begin soon after a qualifying stroke because trial participants received the drug within 72 hours.
Recent studies suggest moderate coffee consumption may support cardiovascular and liver health, while a randomized trial found caffeinated coffee was associated with a 39% lower risk of recurrent atrial flutter among adults with persistent AFib.
Some people gain weight after starting statins, but evidence does not show that the drugs directly cause it. Dietary changes may be a larger factor, while limited animal research has raised questions about possible metabolic effects.
Retinal scans revealed subtle tissue thinning among people who developed atrial fibrillation an average of 4 years later, offering a promising but still unproven path toward earlier risk assessment and closer cardiovascular monitoring.
An AI algorithm found 55 brain aneurysms missed by initial radiologists and delivered a 39% relative increase in detection, but varying results across care settings and unresolved patient outcomes highlight the need for physician oversight and further research.
Research suggests the social hierarchies of adolescence can shape adult health, relationships and expectations for decades, but supportive friendships and a conscious effort to revise old assumptions may weaken the grip of painful school experiences.
An analysis of 51 studies found that healthy diets, exercise, and certain medications changed DNA biomarkers associated with aging, while supplements showed little effect. Researchers caution that these shifts do not prove people remain healthier or live longer.
Artificial intelligence, MRI scans and sleep tracking could help scientists detect unhealthy brain ageing earlier, while research on depression and hibernating squirrels may reveal new treatments. Yet lifestyle, social connection, activity and sleep remain essential.
General anaesthetics globally reduce brain activity, but studies of the thalamus, cortical networks and responsive patients suggest unconsciousness may be more complex than a simple shutdown, offering scientists a rare tool for probing consciousness itself.
Research on the Hadza, Tsimane and San suggests better sleep may depend less on perfect nightly duration and more on circadian cues, cooler temperatures, relaxed evenings, social connection and accepting natural variation.
Doctors serving Pennsylvania’s Amish communities report gravely ill measles patients as hospitals face pressure on scarce isolation rooms. The outbreak has also fueled a dispute between state and federal officials over deaths associated with the virus.
Three Tampa Bay counties have declared emergencies as dengue cases rise, with Hillsborough accounting for 160 of the region’s 169 reported cases and Pinellas preparing for added mosquito control costs that could reach $1 million.
Children may trust AI answers and form attachments before they understand the technology. Pediatrician Edith Bracho-Sanchez urges parents to model careful use, protect opportunities for learning and help children recognize which questions belong with trusted people.
