A new study looks at the connection between psoriasis and kidney disease. And what's the best heart surgery for diabetics.

For diabetics with coronary artery disease in more than one artery, bypass surgery and angioplasty lead to similar long-term benefits. That's the findings of a new study in JAMA. But researchers say in the first two years following treatment, bypass surgery does provide slightly better outcomes in terms of angina relief and fewer physical limitations. After two years, the differences disappeared.

A new study links moderate to severe psoriasis to chronic kidney disease. Researchers in Philadelphia found patients with the severe form of the common inflammatory skin disease were nearly twice as likely to develop chronic kidney disease compared to those without the disease. Severe psoriasis is defined as having 10 percent or more of the body's surface affected.

And new research confirms the safety of a drug commonly prescribed to treat nausea during pregnancy. The study from Denmark found no association between the drug "metoclopramide" (met-oh-CLOH-pro-mide) and an increased risk of major malformations, spontaneous abortions or stillbirths. About 10 to 15 percent of pregnant women receive prescription medication to treat nausea and vomiting.
