Air pollution contributes significantly to diabetes globally New research links outdoor air pollution — even at levels deemed safe — to an increased risk of diabetes globally, according to a new study. The findings raise the possibility that reducing pollution may lead to a drop in diabetes cases in heavily polluted countries such as India and less polluted ones such as the United States.

New measure for stress in overtrained athletes Overload training — or, training to exhaustion followed by a period or rest and recovery before a race — is a method used by many endurance athletes in search of a personal best.

Pulse wave analysis provides reliable information on heart health in young people Arterial stiffness is one of the early signs of cardiovascular disease, and arterial stiffening has been observed in children. A recent study suggests that an easy-to-use, non-invasive method can produce reproducible estimates of arterial stiffness in adolescents aged 16-19 years.

The findings are disturbing because type 2 diabetes among youth is a growing problem. The researchers point to the need to develop new approaches to treat adolescents with the disease.
