Barbarian warriors in Roman times used stimulants in battle

Archaeologists have found evidence that Roman-era barbarian warriors used stimulants before battle, including small spoon-shaped objects attached to their belts. The researchers believe that these stimulants may have been widely used throughout history to motivate soldiers and reduce stress and fear during warfare.

Association of waist circumference with all-cause and cardiovascular mortality in diabetes from the National Health and Nutrition Examination Survey 2003–2018

A U-shaped association between waist circumference and all-cause mortality was found in women, while a J-shaped trend was observed in men with type 2 diabetes. The study suggests that optimal waist circumference thresholds for minimizing mortality risk are 107 cm for women and 89 cm for men.

Emory-led Lancet review highlights racial disparities in sudden cardiac arrest and death among athletes

A recent Lancet review highlights racial disparities in sudden cardiac arrest and death among athletes, with Black athletes facing a significantly higher risk. The study emphasizes the need for increased research into social determinants of health and adequate pre-participation evaluation to mitigate these disparities.
