A cancer therapy that prompts the body’s immune defenses against viruses and bacteria to attack tumors can make patients more vulnerable to heart attack and stroke. A possible explanation for this side effect is that the treatment interferes with immune regulation in the heart’s largest blood vessels, a new study suggests.

Alcohol’s ability to increase people’s pain threshold is one reason that drinking also leads to more aggressive behavior, a new study suggests. Researchers found that the less pain that study participants felt after drinking an alcoholic beverage, the more pain they were willing to inflict on someone else.

Suicide remains a leading cause of death among adolescents. A new study among US high school students has found that suicidal behavior is significantly associated with externalizing behaviors and violence exposure. The new study, appearing in the American Journal of Preventive Medicine, published by Elsevier, is the first to assess this association at the state level.

Eating a diet with a higher ratio of plant-based protein to animal-based protein may reduce the risk of cardiovascular disease (CVD) and coronary heart disease (CHD), according to a new study led by researchers at Harvard T.H. Chan School of Public Health. According to the researchers, these risk reductions are likely driven by the replacement of red and processed meats with plant proteins. The researchers also observed that a combination of consuming more plant protein and higher protein intake overall provided the most heart health benefits.
