Chromium picolinate linked with reduced carbohydrate cravings in people with atypical depression

A randomized, double-blind, placebo-controlled study assessing chromium picolinate supplementation in 113 people with atypical depression found that a subset of patients who reported the highest levels of carbohydrate cravings demonstrated significantly greater reductions than the placebo group on four items on the Hamilton Depression Rating Scale (HAM-D-29): carbohydrate craving, appetite increase, increased eating, and diurnal variation of feeling (mood variation throughout the day). more

Research offers new approach to developing treatments for cocaine and amphetamine addiction  

A methamphetamine epidemic rages across the United States with addicts blinded by uncontrollable desires for a drug that eventually thrusts them into a dire and catastrophic existence. Doctors don't have any effective treatments for these addicts, or for any other drug addicts; drug addiction is a disease that remains a medical mystery. A recent study led by Pastor R. Couceyro, PhD, at Rosalind Franklin University of Medicine and Science and colleagues at Amgen sheds new light on the causes of drug addiction, and opens the possibility for new treatments in the future. These researchers have identified a brain neurotransmitter that is important for the pleasurable, and possibly addictive, effects of stimulant drugs like methamphetamine. more

Two-year study concludes combination treatment with Starlix® and metformin results in a lower incidence of hypoglycemia with effective glycemic control compared to combination therapy with glyburide and metformin 

Researchers reported yesterday that in a two-year, controlled study people with type 2 diabetes receiving Starlix® (nateglinide) in combination with metformin experienced equivalent levels of overall blood glucose control and a lower incidence and severity of hypoglycemia compared to the those taking the commonly used sulfonylurea agent, glyburide, in combination with metformin. This trial is the first to prospectively evaluate the long-term safety and efficacy of the Starlix/metformin combination for two years. Researchers also observed that treatment with Starlix plus metformin was weight neutral, while participants in the glyburide/metformin arm of the trial gained about 1 kg over the two-year study period. more

Free CDC tool kit on concussion for high school coaches!

Concussions can happen to any athlete—male or female—in any sport. Concussions are a type of traumatic brain injury (TBI), caused by a blow or jolt to the head that can range from mild to severe and can disrupt the way the brain normally works. More than 300,000 people sustain sports- and recreation-related TBIs every year in this country. Coaches, athletic directors and trainers play a key role in helping to prevent concussion and in managing it properly if it occurs. more
