A U.S. study found 32 genetic mutations associated with Crohn's disease, including three genes that have been previously linked to type 1 diabetes and asthma. The lead researcher said there could be hundreds of genes tied to the disease.
A Phase III study of Avastin combined with a standard chemotherapy showed improved survival rates for patients with metastatic colorectal cancer regardless of K-Ras gene mutations. Avastin combined with IFL chemotherapy resulted in an 82% increase in survival without disease progression in patients with normal K-Ras genes and a 69% increase in patients with the K-Ras gene mutation.
A study found that women colon cancer patients under age 50 are half as likely to die from the disease as their male peers, but women over age 50 are 38% more likely to die of the disease than men. Researchers say estrogen may be the protective factor.
People who consume more fruit and fiber are more likely to have healthier body weights, according to researchers at the University of Texas at Austin. All participants in their study had the same calorie intake but ate different foods.

One expert involved in creating the guidelines said the average American should walk, jog or run about nine or 10 miles every week.
