Variation in immune response gene causes age-related macular degeneration when triggered

A Columbia University/University of Iowa study reveals that inherited variations in the Factor H gene may trigger age-related macular degeneration through inflammation and immune responses. Researchers found that targeting molecules involved in immune system response could lead to powerful new therapies for treating and preventing AMD.

Male combat veterans rank high in heart disease risk

A recent study by the Life Course Socio-Economic Status (LCSES) study found that male combat veterans are more likely to be heavy drinkers and smokers compared to non-veterans and non-combat veteran controls. The researchers also discovered that older men with distant combat exposure had higher odds of obesity and physical inactivity.
