Lack Of Happiness Hormone Serotonin In The Brain Causes Impaired Maternal Behavior In Mice
A lack of serotonin, commonly known as the "happiness hormone", in the brain slows the growth of mice after birth and is responsible for impaired maternal behavior later in life. This was the result of research conducted by Dr. Natalia Alenina, Dana Kikic, and Professor Michael Bader of the Max DelbrÃøck Center for Molecular Medicine (MDC) Berlin-Buch, Germany. At the same time, the researchers discovered that the presence of serotonin in the brain is not crucial for the survival of the animals. Furthermore, they were able to confirm that there are two strictly separate pathways of serotonin production: One gene is responsible for the formation of serotonin in the brain, another gene for the production of the hormone in the body (PNAS, June 23, 2009, Vol. 106, No. 25, pp 10332-10337)*.

Novel Non-Surgical Therapy Dramatically Increases Weight Loss In Obese Patients; Results From Pilot Clinical Study Presented At ASMBS
GI Dynamics, a leader in non-surgical treatments for type 2 diabetes and obesity, today announced results from a pilot clinical study which demonstrated the substantially enhanced weight loss effects of combining the company"s EndoBarrier Gastrointestinal Liner with a new EndoBarrier Flow Restrictor. The EndoBarrier Flow Restrictor provides an adjustable restriction at the outlet of the stomach and is designed to delay gastric emptying, an additional mechanism which adds to the therapeutic effects of the liner. The results were presented today at the 26th annual meeting of the American Society for Metabolic and Bariatric Surgery (ASMBS).

Bike Paths, Other 'Healthy' Infrastructure Projects Proving Controversial
"Attempts to set billions aside for infrastructure projects like bike paths face an uphill battle on Capitol Hill," The Chicago Tribune reports, adding "GOP legislators see no health savings in parks and similar projects," while advocates say preventive efforts will bring down costs. "A draft Senate bill would provide up to $10 billion annually for a "prevention and public health investment fund" -- a portion of which could be used for projects such as bike paths, sidewalks, farmers markets and other community interventions meant to curb chronic and costly conditions like obesity."

Catastrophic Sports Injury Report Released

The National Center for Catastrophic Sports Injury Research based at the University of North Carolina at Chapel Hill has released its 26th annual all sports report. In addition to collecting data on catastrophic injuries in all high school and college sports, the report also contains cheerleading injury data. The latest figures are from the 2007-2008 academic year. The report defines catastrophic injuries as any severe injury incurred during participation in a school or college sponsored sport, and includes three categories: fatal; non-fatal (resulting in permanent severe functional disability); and serious (no permanent functional disability but severe injury). Sports injuries are also considered direct (resulting directly from participation in the skills of the sport) or indirect (caused by exertion while participating in a sport or a complication secondary to a non-fatal injury). The report"s conclusions for the 26-year period from the fall of 1982 through the spring of 2008 include: -- There were 1,116 direct catastrophic injuries in high school (905) and college sports (211). High school sports were associated with 152 fatalities, 379 non-fatal and 374 serious injuries. College sports accounted for 22 fatalities, 63 non-fatal and 126 serious injuries. -- Cheerleading accounted for 65.2 percent of high school and 70.5 percent of college catastrophic injuries among all female sports. The report"s author and center director, Frederick O. Mueller, Ph.D., professor of exercise and sports science in UNC"s College of Arts and Sciences, noted that the number of cheerleading injuries fell slightly in 2007-08 year. "Progress has been slow, but there has been an increased emphasis on cheerleading safety," Mueller said. "Continued data collection on all types of cheerleading injuries will hopefully show that these safety measures are working to reduce injuries." University of North Carolina at Chapel Hill
