Long-term depression linked with life-threatening chronic disease, earlier death

The first symptoms of major depression may be behavioral, but the common mental illness is based in biology — and not limited to the brain. In recent years some studies have linked major, long-term depression with life-threatening chronic disease and with earlier death, even after lifestyle risk factors have been taken into account.

Metal-on-metal hip implants cause inflammation of joint lining long before symptoms appear

Metal-on-metal hip implants can cause inflammation of the joint lining (synovitis) long before symptoms appear, and magnetic resonance imaging (MRI) can be used to identify this inflammation, according to a new study by researchers at Hospital for Special Surgery. The study, which appears in an upcoming issue of the Journal of Bone & Joint Surgery, demonstrates that MRI can be used to identify implants that are going to fail before people become symptomatic.
