Cumulative cardiovascular health from early adulthood predicts lower disease risk

The American Heart Association's Life's Essential 8 (LE8) score is a health tool, ranging from 0 to 100, that quantifies cardiovascular health (CVH) using information from eight lifestyle and risk factors, (body mass index, cholesterol, blood pressure, blood glucose, physical activity, diet, smoking, and sleep.

Obesity may leave immune cells stuck in inflammatory mode after weight loss

A new EMBO Reports study suggests that obesity can leave a lasting epigenetic imprint on CD4 T cells, delaying the restoration of adaptive immune balance after weight loss. Using mouse models and human cohorts, researchers linked this immune “memory” to DNA methylation changes, saturated fatty acids, autophagy, and immune senescence.
