In a study of 5,125 women with diabetes, women who were physically active had substantially reduced risk for heart disease and stroke (Article, p. 96). Exercise, such as regular walking, reduced risk for cardiovascular disease; faster walking pace was associated with even lower risk. Cardiovascular disease is the leading cause of death in persons with diabetes mellitus.
In a study of 59 patients with the combination of ulcerative colitis and primary sclerosing cholangitis (PSC), those who had received the drug ursodiol were less likely to develop colon cancer or precancerous changes in the colon than those who did not (Article, p. 89). People with both ulcerative colitis, an inflammatory disease of the colon, and PSC, a disease of the bile ducts or biliary tract, are at very high risk for colorectal cancer. Ursodiol is a drug with relatively few side effects that is sometimes used to treat liver abnormalities in PSC patients. Although it is not clear that ursodiol would reduce cancer risk in other groups of high-risk patients, the authors and an editorial say a randomized trial should be done (Editorial, p. 158).
