April 26, 2012 - Brain scans may be able to predict who will become overweight. In a study published in The Journal of Neuroscience, researchers demonstrated a connection between F-MRI responses to appetite driven cues and future behavior. Researchers at Dartmouth used brain imaging to analyze the brain activity of patients as they looked at pictures of food. Those who had the most activity in a part of the brain known as the reward center were more likely gain weight six months later.The researchers note that the first step toward controlling cravings may be an awareness of how much you are affected by specific triggers in the environment, such as the arrival of the dessert tray in a restaurant.

Also, preliminary research shows, treatment with testosterone may help heart failure patients feel better and exercise more. The finding comes from four small studies of people with heart failure. The researchers analyzed the results from all of those studies and found that those who took testosterone supplements were able to exercise longer than those who didn't. Testosterone occurs naturally in men and women. But testosterone levels decline with age, which can contribute to decreases in muscle mass and strength. Even though patients in the trials appeared to benefit from supplemental testosterone, larger and longer studies are needed to prove the treatment is safe and effective.
