High-dose folic acid appears safe from formaldehyde toxicity

Folic acid – an essential vitamin added to flour and cereals and prescribed at high doses for cancer patients and people with blood disorders – does not elevate toxic formaldehyde in the body, according to a new Cornell University study on mice and human cancer patients who consumed high doses.

Daraxonrasib shows durable responses in RAS-mutant lung cancer

Daraxonrasib, an oral RAS inhibitor therapy, achieved durable responses in pretreated patients with RAS-mutant non-small cell lung cancer (NSCLC) in a Phase 1/2 trial led by The University of Texas MD Anderson Cancer Center.

Newly diagnosed AML patients benefit from less-intensive combination treatment

Investigators from the Mass General Brigham Cancer Institute have found that adults with newly diagnosed acute myeloid leukemia (AML) receiving a less-intensive combination of azacitidine and venetoclax had more than twice as much time before treatment failed, the leukemia returned or worsened, or they died, compared with patients receiving intensive chemotherapy.

Bright light therapy boosts activity and sleep in older adults

Bright light therapy lamps can improve sleep, activity levels and circadian rhythms of older adults in urban areas who have diminished exposure to natural light, a new study from the University of Surrey reports.

Progesterone levels linked to brain patterns underlying mood changes

The influence of the hormone progesterone on mood is well known. Now researchers from the University of Barcelona have shown how higher levels of progesterone during the menstrual cycle are linked to less distinct patterns of activity in areas of the brain involved in controlling emotions.

AI learned from cardiologists’ notes, and needed far less labeled ECG data

By teaching an AI system to connect raw heart signals with the clinical insights contained in cardiologists’ reports, researchers tested whether routine ECGs could reveal more with far fewer labeled examples.

Menopause may start changing the gut years before periods stop

A longitudinal study of 964 women found that blood markers of gut epithelial barrier dysfunction and microbial product translocation began to rise around 2 to 2.5 years before the final menstrual period and remained elevated after menopause. The findings suggest that changes in gut barrier integrity may form part of the biological transition through menopause and could help explain links between menopause, inflammation, and later health outcomes.

Why addiction researchers are paying closer attention to GLP-1 drugs

A Journal of Clinical Investigation Viewpoint highlights growing evidence that GLP-1 receptor agonists, particularly semaglutide, may reduce alcohol consumption and some other substance-related outcomes by acting on brain systems involved in reward, motivation, stress, and emotion. However, the authors caution that efficacy for substance use disorders is not yet firmly established and call for further research into optimal dosing, treatment duration, patient selection, mechanisms, and effects across different addictions.

Your weekend meal schedule may matter more than you think

In a prospective analysis of 104,806 adults from the NutriNet-Santé cohort, greater differences in meal timing between weekdays and weekends were associated with higher risks of cardiovascular disease and coronary heart disease in men over a median 8.1 years. The associations were strongest when weekend eating shifted earlier, while delayed weekend eating was linked specifically to coronary heart disease, with no association detected for cerebrovascular disease.
