If You Always Have Room For Dessert, Ghrelin May Be To Blame
Date: Jun-27-2012A new study suggests that the appetite-inducing hormone ghrelin increases the incentive for humans to eat high-calorie foods, even on a full stomach. The results were reported at The Endocrine Society's 94th Annual Meeting in Houston. In the study, rats lacking the ghrelin receptor gene ate less of a sweet treat after a full meal than did rodents whose ghrelin receptor gene was intact...
Male Cancer Patients Improve Muscle Strength With Experimental Drug
Date: Jun-27-2012An experimental medication safely increases muscle strength and physical functioning among cancer patients with low testosterone levels, a new drug study finds. The results were presented at The Endocrine Society's 94th Annual Meeting in Houston. The medication, called enobosarm, is the first of a new class of drugs known as selective androgen receptor modulators, which are similar to steroids in their growth-enhancing effects but, potentially, have fewer side effects...
Improved Diagnosis Of Metabolic Syndrome In Children
Date: Jun-27-2012Researchers have developed a new scoring system that may better identify adolescents with the metabolic syndrome, a group at increased risk of later developing Type 2 diabetes and heart disease. The study, presented at The Endocrine Society's 94th Annual Meeting in Houston, describes what the authors call "the first racial/ethnic-specific and sex-specific scoring system for the metabolic syndrome...
Physical Fitness May Improve Survival Among Diabetes Patients With Heart Dysfunction
Date: Jun-27-2012Being physically fit may improve survival rates among diabetes patients with a particular type of heart abnormality, a new study determines. The results were presented at The Endocrine Society's 94th Annual Meeting in Houston. In the United States, nearly 26 million people have diabetes, according to the American Diabetes Association. Being overweight or obese increases the risk of diabetes, and more people are developing the disease as the obesity epidemic continues. Treatment includes making lifestyle changes and taking medication to control blood sugar...
Sitagliptin Improves Reactive Hypoglycemia Symptoms
Date: Jun-27-2012The diabetes drug sitagliptin appears to reduce the severity of reactive hypoglycemia, a form of low blood sugar that occurs after a meal, a preliminary study finds. The results were presented at The Endocrine Society's 94th Annual Meeting in Houston. "Further studies may determine if it is possible to use sitagliptin as a novel approach to treat this condition, for which there currently is no medical therapy," said the lead investigator, Francisco Gomez-Perez, MD, of Instituto Nacional de Ciencias Medicas y Nutricion SZ in Mexico City...
Integrated, On-Going, Mental Health Care Needed For Offenders
Date: Jun-27-2012Offenders with mental health problems need improved and on-going access to health care, according to the first study to systematically examine healthcare received by offenders across the criminal justice system. A new report from Peninsula College of Medicine and Dentistry, Plymouth University, and the Centre for Mental Health, suggests that prison and community sentences offer the best opportunities to provide this...
News From The Journal Of Clinical Investigation: June 25, 2012
Date: Jun-27-2012INFECTIOUS DISEASE Oxidative stress fuels Trypanosoma cruzi infection in mice Trypanosoma cruzi is a parasitic flagellate protozoa that causes Chagas disease. Dr. Claudia Paiva and colleagues at the Universidade Federal of Rio de Janeiro in Brazil report on how oxidative damage produced by immune cells contributes to the parasite burden. Using a mouse model of T. cruzi infection, they report that induction of a protein called NRF2 and heme-oxygenase-1 (HO-1) mounted antioxidant defenses during infection that enhanced infection...
Large Waist Sizes In Women Related To Decreased Infertility
Date: Jun-26-2012Nuffield Health, the UK's largest health charity, published an article today showing that women with larger waist sizes are at great risk of cancer, including breast cancer. They also have increased chance of infertility. The data was compiled from nearly 55,000 women taking the Nuffield 'Health MOT', a series of tests that takes about an hour and assesses overall fitness and health. Parameters included body mass index (BMI), resting heart rate, cholesterol, aerobic fitness, blood pressure, and sugar levels...
The Internet - Men And Women Have Different Preferences
Date: Jun-26-2012Psychologists from the Department of Psychology at the University of Bath, England, have discovered in their research that over the past 10 years, the difference between how men and women use the Internet has become even more significant. While surfing the Internet, men were more likely to visit entertainment, games and music websites. Women, on the other hand, were more apt to check out social networking sites, researchers claim. After the introduction of Facebook, Twitter, and MySpace, women started to focus most of their time surfing on these types of sites...
Low-fat, Low-glycemic And Low-carb Diets Compared
Date: Jun-26-2012A low-fat diet may put people at the highest risk for gaining their weight back, because it decreases their resting energy expenditure and total energy expenditure more than other diets, such as a low-glycemic index diet and a very low carbohydrate diet. A team of investigators from Children's Hospital Boston published their preliminary research in JAMA while studying the effects on energy expenditure and components of the metabolic syndrome of these 3 common diets. A low-fat diet requires a limited amount of fat, most importantly saturated fat, cholesterol, and total caloric intake...
