New Research Finds That Bingeing Increases Opioids In Brain Area That Controls Food Intake
Overconsumption of fatty, sugary foods leads to changes in brain receptors, according to new animal research at Johns Hopkins University School of Medicine. The new research results are being presented at the 2009 annual meeting of the Society for the Study of Ingestive Behavior (SSIB), July 28 - August 1, 2009, the foremost society for research into all aspects of eating and drinking behavior. The results have implications for understanding bulimia and other binge eating disorders.

Media Looks At County-Level HIV, AIDS Map Data
Major population centers such as those in New York and California have the highest numbers of HIV cases, however, many of the areas that have the highest rates of people with HIV are in the South, according to data from an online mapping tool launched by the National Minority Quality Forum yesterday, the AP/Minneapolis Star Tribune reports. The map, which is the first tool of its kind to look at HIV and AIDS cases on a county level, is based on 2006 data collected from states and cross-checked with CDC data. According to the mapping tool, of the 48 counties with the highest HIV prevalence rates, 25 are in Georgia. In addition, Florida, Georgia, South Carolina and Virginia have the highest prevalence rates for HIV cases that have progressed to AIDS (Stobbe, AP/Minneapolis Star Tribune, 6/22). In Virginia, Richmond, Petersburg and Norfolk were among the nation"s urban areas hardest hit by HIV/AIDS (Smith, Richmond Times-Dispatch, 6/23). Three metro counties in Kansas City, Mo., have HIV and AIDS rates that are higher than about 80 percent of counties nationwide, according to the data, NBC Action News reports (Ptacek, NBC Action News, 6/22).

Study Suggests Preseason Shoulder Strength May Determine Injury Severity For Baseball Pitchers

Athletic injuries can derail any player"s ability to compete, but for a baseball pitcher his shoulder strength and control is critical. A new study to be presented at the American Orthopaedic Society for Sports Medicine"s (AOSSM) Annual Meeting in Keystone, Colorado, suggests that testing a pitcher"s shoulder strength through a series of exercises during the preseason may help create a focused strength training program to prevent serious injury during the season. "The ability to identify pitchers at risk for injury could be extremely valuable to a professional baseball organization. Our study examined the predictive value of preseason strength measurements as they relate to in-season throwing injuries," said Ian Byram MD, lead author and fourth year orthopaedic surgery resident at Vanderbilt Medical Center, Nashville, TN The study measured the preseason shoulder strength for all pitchers in a professional baseball organization over a five-year period (2001-2005). Over the course of the five-year period, 144 major and minor league baseball pitchers were analyzed using a specific protocol by a single athletic trainer. Prone internal rotation (IR), prone external rotation (PER), seated external rotation (SER) and supraspinatus (SS) strength were tested during spring training prior to each season. The players were then followed throughout the season for incidence of throwing related injury. The study illustrated a significant association between PER, SER and SS strength with throwing related injuries requiring surgery. There was also some evidence for an association between the ratio of PER/IR strength and the incidence of injury. "The shoulder and elbow are subjected to significant stresses during the pitching motion, placing them at risk for injury. By demonstrating an association between shoulder weakness and throwing related injuries, we hope that future injuries might be prevented by focusing strength training programs on those areas that are weakest," said Byram.
