Certain scores may predict which trauma patients face high risk of multiple infections
Trauma patients are at risk of developing multiple infections while in the hospital, but it’s difficult to identify those who are especially susceptible. Now a team at Massachusetts General Hospital (MGH) has found that certain scores already used to assess…
Family history misses identifying individuals with high genetic risk of CVD or cancer
Certain genetic changes, termed “pathogenic variants,” substantially increase risk for cardiovascular disease and cancer–the leading causes of death–but testing to identify individual carriers is not part of current clinical practice.
