High-dose vitamin D in pregnancy likely cuts childhood wheeze risk, but infant supplements fall short

Rss Feed - Wed, 08/13/2025 - 21:27
A Cochrane review of 18 randomized trials found that high-dose vitamin D during pregnancy likely reduces the risk of childhood wheeze, a key early symptom of asthma. However, vitamin D supplementation in infants and young children showed uncertain benefits for asthma prevention.

Pregabalin raises heart failure risk in older adults compared to gabapentin, study finds

Rss Feed - Wed, 08/13/2025 - 20:39
A large Medicare cohort study found that older adults prescribed pregabalin had a significantly higher risk of developing heart failure compared to those prescribed gabapentin. The elevated risk was most pronounced in individuals with pre-existing cardiovascular disease, especially women and White patients.

Pandemic left measurable changes in teen brains, hormones, and immunity

Rss Feed - Wed, 08/13/2025 - 19:58
Adolescents assessed after COVID-19 lockdowns showed lower daily cortisol, higher inflammation, and reduced prefrontal cortex activity compared to matched pre-pandemic peers, suggesting widespread stress-related biological changes. These alterations mirror patterns seen after prolonged early-life stress, raising concerns about long-term health risks.

Curcumin activates SIRT3 to protect bone structure in diabetic mice

Rss Feed - Wed, 08/13/2025 - 19:23
In a new Scientific Reports study, curcumin protected bone-forming cells from high-glucose damage by activating the SIRT3/FoxO3a/NRF2 antioxidant pathway and restoring mitochondrial health. In diabetic mice, curcumin improved bone density and oxidative balance, highlighting its potential in osteoporosis prevention.
