BY EMILY UNDERWOOD: When a 53-year-old man asked Dutch doctors to treat his obsessive-compulsive disorder (OCD) several years back, they suggested a new but promising surgical treatment: implanted electrodes that would stimulate deep brain tissue involved in decision-making, reward-seeking, and motivation. The treatment apparently helped him go off one of his psychiatric medications, but it came with a surprising side effect—it also seemed to improve his type 2 diabetes. Now, researchers think they know why. A new study suggests that a boost in the activity of dopamine, a neurotransmitter involved in motivation and pleasure, improves the body’s ability to process sugar. (read more)
BY NEWS MEDICAL: One of the largest studies to date on nuts and diabetes was published today in Diabetologia, the journal of the European Association for the Study of Diabetes (EASD). The study shows that approximately two ounces of nuts a day, as a replacement for carbohydrate foods, can improve glycemic control and blood lipids in those with type 2 diabetes.
Researchers from the University of Toronto and St. Michael’s Hospital in Toronto, Canada, found that tree nuts (almonds, Brazils, cashews, hazelnuts, pecans, pine nuts, pistachios, macadamias and walnuts) and peanuts improved blood lipid levels and blood sugar levels in individuals with non-insulin dependent diabetes.

BY HALLIE LEVINE: T ype 2 diabetes is both common and on the rise. The disease—which occurs when your body is unable to use insulin to adequately control levels of blood glucose, the energy from food that fuels our cells and organs—affects more than 30 million Americans. About 12 million are older than 65, according to a Centers for Disease Control and Prevention report released last year.
Just as alarming: About 84 million adults—half of them older than 65—have prediabetes, glucose levels high enough to put them in danger of developing diabetes. (read more)
BY LISA RAPAPORT: Adding a test normally used for diabetes monitoring to employee wellness exams could identify people who don’t have the disease but are at high risk of developing it, a recent study suggests.
Researchers examined data from two different types of blood sugar test for more than 34,000 participants in a U.S. employee wellness program who didn’t have diabetes. At the start of the study, they all also had fasting blood sugar in a healthy range. (read more)
BY NEWS MEDICAL: New research co-authored by Professor Stephanie Amiel, RD Lawrence Professor of Diabetic Medicine, and published in Diabetologia identifies key areas of the brain that change patients’ ability to recognize hypoglycemia.
People with type 1 diabetes are often unable to regulate their blood sugar so it can become dangerously high (hyperglycemia) or dangerously low (hypoglycemia). If left untreated, blood sugar levels can fall below the threshold for maintaining brain function leading to unconsciousness and even death. (read more)
