Maternal mental health screening key to heart health

Routine screening and treatment for depression and anxiety during and after pregnancy could improve long-term cardiovascular health for both mothers and children, according to a new American Heart Association (AHA) scientific statement published today in The Journal of the American Heart Association. The statement highlights the strong link between maternal psychological health and cardiovascular outcomes, emphasizing the need for multidisciplinary care teams to monitor and support mental health during the perinatal period. Experts urge healthcare professionals to integrate psychological screening alongside traditional cardiovascular risk assessments to address modifiable factors early.

1 night of sleep deprivation alters immune system, raises inflammation risk

Just one night of sleep deprivation can shift immune cell profiles to resemble those seen in individuals with obesity, a condition linked to chronic inflammation and disease risk, according to new research in The Journal of Immunology. The study found that 24 hours without sleep altered monocytes—key immune cells—in healthy individuals, suggesting sleep plays a critical role in regulating inflammation. Researchers warn that chronic sleep disturbances may contribute to long-term health risks, including obesity, diabetes, and cardiovascular disease, underscoring the need for better sleep hygiene and public health interventions.

Study finds high levels of added sugar in U.S. infant formula

Most infant formulas on the U.S. market contain high levels of added sugars rather than the naturally occurring lactose found in cow’s milk, according to a new study from the University of Kansas published in the Journal of Food Composition and Analysis. Researchers found that 60% of sugars in standard formulas and 85% in lactose-free varieties came from added sources like corn syrup and glucose—ingredients linked to obesity, diabetes, and cardiovascular disease. With no federal regulations requiring disclosure of sugar sources, parents have little way of knowing what’s in their baby’s formula, raising concerns about long-term health impacts.
