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).

'Taking Up A Dialogue' With The Brain: Letter Decoding From Single-trial Brain Signals
Brain-computer interfaces "translate" what a person is thinking in words or actions. Researchers from Maastricht University in the Netherlands performed functional MRI brain scans on healthy participants, instructing them to "type" by performing mental tasks corresponding to different letters in the English alphabet. Researchers were able to use signals from the participants" brain activation patterns to decode information about the intended letter that a participant was thinking about, and to use this in a conversation with the experimenters without any spoken words. It is hoped that such technology can enable communication with "locked-in" patients or assessment of consciousness in non-responsive patients.

Sleep And Weight Gain: A Molecular Link

There appears to be a link between sleep and weight control, with some studies indicating that sleep disruption can increase weight gain and others that diet affects sleep. Victor Uebele and colleagues, at Merck Research Laboratories, West Point, have now provided further evidence to support this association by showing that T-type calcium channels regulate body weight maintenance and sleep in mice. These data suggest that sleep and circadian treatment approaches may be of benefit in the fight against obesity. Previous studies have shown that mice lacking the CaV3.1 T-type calcium channel have disrupted sleep/wake activity. In this study, the researchers found that these mice were resistant to weight gain when fed a high-fat diet. Consistent with these data, when normal-weight rodents were administered a drug that specifically antagonized T-type calcium channels during their inactive phase they showed increased sleep and were protected from weight gain due to a high-fat diet. Further, when the same drug was given to obese rodents it reduced body weight and fat mass. The authors conclude that the benefits of the drug are likely to be a result of better alignment of feeding patterns and the circadian rhythm, and that targeting T-type calcium channels might provide a new avenue of research for those developing drugs to treat obesity.
