You don't need 10,000 steps a day to benefit your heart, cardiologists say

A new American College of Cardiology scientific statement recommends integrating individualized exercise prescriptions into routine cardiovascular care, drawing on evidence supporting aerobic activity, resistance training, and cardiac rehabilitation. The authors emphasize that previously inactive individuals have the most to gain from increasing physical activity, while exercise recommendations should consider individual health conditions, functional capacity, and safety.

A CDC survey finds 4 in 5 US teenagers fall short of high heart health scores

A CDC study of 5,192 US high school students found that approximately 80% had low or moderate cardiovascular health scores based on five measures assessed in a national survey. Diet, sleep, and physical activity received the least favorable scores, with differences observed across sex, grade, and racial and ethnic groups.

AI study of 101,000 patients links brown fat to heart and mental health

In a retrospective analysis of PET-CT records from 101,243 patients, researchers found that detectable brown fat was associated with lower prevalence of cardiometabolic and psychiatric conditions, while greater activity, particularly in the axillary region, was linked to more favourable metabolic outcomes. Medication screening identified losartan, which increased brown fat thermogenic activity in laboratory experiments and energy expenditure in mice, although its effects on human brown fat remain unproven.

A study of 2.3 million California children raises questions about lithium in water

Researchers analyzed healthcare records from more than 2.3 million children in California and found that those living in counties with higher lithium concentrations in water sources had 60% higher adjusted odds of a Wolff-Parkinson-White (WPW) diagnosis. A separate New York analysis supported an association at a lower lithium threshol

Novel gene rejuvenation therapy preserves cell identity while reversing age

Every organ and tissue progressively loses function and integrity as it ages. In fact, researchers have identified "hallmarks of aging" that not only present specific processes impacted by age, but are also thought of as levers that, if successfully targeted, could help turn back the aging clock and result in tissue rejuvenation.

Early vasopressin use does not improve septic shock survival

A new study from researchers at Intermountain Health in Salt Lake City found that starting an advanced medication earlier for critically ill patients with life-threatening septic shock does not improve their survival, shorten hospital stays, or improve their recovery compared with waiting until their condition potentially worsens.
