It's estimated that nearly 80% of men who undergo surgery to remove the prostate gland suffer from sexual dysfunction caused by nerve damage. Now, research out of the University of Pittsburgh finds gene therapy may help prevent that side effect. The therapy under study helps trigger nerve cells to start repairing themselves. Rats who received gene therapy showed signs of recovering function to muscles controlled by the nerve damaged during surgery. The therapy is given before surgery.
The researchers say they hope the concept can be translated into humans, enabling gene therapy to be used as preventive treatment for men undergoing surgery to remove their prostate glands.
Prostate Cancer is the most common type of cancer found in American men, other than Skin Cancer. The American Cancer Society estimates that there will be about 220,900 new cases of Prostate cancer in the United States in the year 2003. About 28,900 men will die of this disease. Prostate Cancer is the second leading cause of cancer death in men, exceeded only by Lung Cancer. While one man in six will get Prostate Cancer during his lifetime, only 1 man in 32 will die of this disease. The death rate for Prostate Cancer is going down, and the disease is being found earlier as well.
Two new studies may refuel the debate over the connection between dietary fiber and the risk for Colorectal Cancer. Both studies found an association between eating a diet rich in fiber and reducing your risk of Colon Cancer. The first study looked at nearly a half million people and found that those who ate the most fiber had a 40% lower risk of the disease than people who ate the least amounts of fiber. The second study compared fiber intakes between a group of patients with benign colon tumors called Adenomas and patients without the growths. And patients in that study who ate the most fiber had 25% fewer growths than people who ate the least fiber. Fiber rich foods include whole grains, leafy green vegetables and fruits. Both studies are published in the Lancet Medical Journal.
If following a diet and exercise plan is hard for you, attention deficit disorder may be part of the problem. A recent study compared the weight loss of adult patients who were newly diagnosed with ADHD or with several symptoms and discovered some surprising links. Patients with ADHD symptoms lost half as much weight in a weight loss program, and took longer to do it than non ADHD patients. The study from the behavioral medical center for treatment and research in Portland, Oregon suggests that the attention robbing disorder plays a role in the ability to follow diet and exercise programs.
