Computer analysis of EEG patterns suggests a potential diagnostic test for autism at two years old Posted: 25 Jun 2012 05:30 PM PDT The largest, most rigorous study to date to investigate EEGs as a potential diagnostic tool for autism offers hope for an earlier, more definitive test. Widely available EEG testing can distinguish children with autism from neurotypical children as early as age two. Findings could be the basis for a future objective diagnostic test of autism particularly at younger ages when behavior-based measures are unreliable.

Genetic heart diseases may be responsible for unexplained stillbirths Posted: 25 Jun 2012 05:28 PM PDT Genetic researchers have made an important step towards resolving the mystery of the causes of intrauterine fetal demise (IUFD), or stillbirth, where a baby dies in the womb after the 14th week of gestation. IUFD is responsible for 60% of perinatal mortality and occurs in about one in every two hundred pregnancies in Europe. Up to half of these stillbirths are unexplained. Now scientists have found that up to 8% of these unexplained deaths may be caused by specific genetic heart conditions.

'Dessert with breakfast diet' helps avoid weight regain by reducing cravings Posted: 25 Jun 2012 09:50 AM PDT Dieters have less hunger and cravings throughout the day and are better able to keep off lost weight if they eat a carbohydrate-rich, protein-packed breakfast that includes dessert.

Ratio of appetite-regulating hormones marker of successful dieters Posted: 25 Jun 2012 09:50 AM PDT A pre-diet measurement of two hormones related to weight regulation can help predict which dieters will be more likely to maintain their weight loss and who will not, according to a new study.

Secondhand smoke is linked to type 2 diabetes and obesity Posted: 25 Jun 2012 09:50 AM PDT Adults who are exposed to secondhand smoke have higher rates of obesity and Type 2 diabetes than do nonsmokers without environmental exposure to tobacco smoke, a new study shows.

Experimental insulin drug prevents low blood sugar Posted: 25 Jun 2012 09:50 AM PDT An experimental insulin drug prevented low blood sugar among diabetic patients more often than a popular drug on the market, a new study finds.

Why do fat cells get fat? New suspect identified Posted: 25 Jun 2012 09:49 AM PDT As the world fights obesity at the human level, a new finding at the microscopic level could help fuel that fight. The work helps explain why fat-storing cells get fatter, and burn fat slower, as obesity sets in -- and could lead to new obesity drugs.

Overweight men can boost low testosterone levels by losing weight Posted: 25 Jun 2012 09:49 AM PDT Weight loss can reduce the prevalence of low testosterone levels in overweight, middle-aged men with prediabetes by almost 50 percent, a new study finds.

Gut hormone receptor in brain is key to gastric emptying rate; may help prevent obesity Posted: 25 Jun 2012 09:49 AM PDT Researchers have discovered how a hormone in the gut slows the rate at which the stomach empties and thus suppresses hunger and food intake.

Type 2 diabetes, cured by weight loss surgery, returns in one-fifth of patients Posted: 25 Jun 2012 07:09 AM PDT A new study shows that although gastric bypass surgery reverses Type 2 diabetes in a large percentage of obese patients, the disease recurs in about 21 percent of them within three to five years.
