(HealthDay)—Regularly smoking pot is associated with visceral adiposity and adipose tissue insulin resistance, but not other metabolic changes such as impaired β-cell function or hepatic steatosis, according to a study published online March 25 in Diabetes Care. http://medicalxpress.com/news/2013-04-pot-linked-metabolic.html Diabetes Fri, 19 Apr 2013 16:50:01 EST news285603337 Scientists at Harvard may have new hope for anyone who's tried to fight the battle of the bulge. New research, conducted in collaboration with researchers at Massachusetts General Hospital, has found that the gut microbes of mice undergo drastic changes following gastric bypass surgery. Transfer of these microbes into sterile mice resulted in rapid weight loss. The study is described in a March 27 paper in Science Translational Medicine. http://medicalxpress.com/news/2013-03-weight-gut-microbiota-role-loss.html Medications Wed, 27 Mar 2013 14:00:15 EST news283610632 Poor diet and lifestyle choices set the stage for obesity and diabetes, but the immune system plays a relatively underappreciated role in accelerating this process. Metabolic changes in fat cells stimulate the release of inflammatory signals known as cytokines, which block insulin signaling at a cellular level, as well as other factors that recruit immune cells into fatty tissue to perpetuate the cycle of declining metabolic function. http://medicalxpress.com/news/2013-03-protein-fat-cells-inflammatory-gears.html Medical research Fri, 15 Mar 2013 09:24:26 EST news282558150 In a substudy of the STAMPEDE trial (Surgical Therapy And Medications Potentially Eradicate Diabetes Efficiently), Cleveland Clinic researchers have found that gastric bypass surgery reverses diabetes by uniquely restoring pancreatic function in moderately obese patients with uncontrolled type 2 diabetes. http://medicalxpress.com/news/2013-02-bariatric-surgery-pancreatic-function-belly.html Surgery Tue, 26 Feb 2013 08:50:06 EST news281090146 Epidemiologists at Boston University School of Public Health (BUSPH) have found that pre-pregnancy obesity and excess weight gain during pregnancy in African-American women are associated with an increased risk of giving birth to an abnormally large baby. Macrosomia, which is defined as a newborn weighing more than 4,000 grams at birth (approximately 8.8 pounds), can cause delivery complications such as hemorrhage, infection, the need for a caesarean section, preeclampsia and perinatal mortality. The study, which appears online in the journal Obesity, was conducted by researchers at the Slone Epidemiology Center using data from 59,000 African-American women participating in the Black Women's Health Study. http://medicalxpress.com/news/2013-02-obesity-excess-weight-gain-pregnancy.html Overweight and Obesity Mon, 11 Feb 2013 12:59:48 EST news279809980 (HealthDay)—Grape polyphenol (PP) supplementation prevents fructose-induced oxidative stress and insulin resistance in healthy volunteers with high metabolic risk, according to research published online Dec. 28 in Diabetes Care. http://medicalxpress.com/news/2013-02-grape-polyphenols-counteract-fructose-induced-effects.html Diabetes Mon, 04 Feb 2013 05:10:01 EST news279175097 (HealthDay)—People with insomnia may have double the chances of a heart attack or stroke as opposed to those who sleep well, a study by Taiwanese researchers suggests. http://medicalxpress.com/news/2012-11-insomnia-heart.html Health Mon, 05 Nov 2012 10:30:02 EST news271332395 Cancer cells grow fast.

But what if lack of exercise itself were treated as a medical condition? Mayo Clinic physiologist Michael Joyner, M.D., argues that it should be. His commentary is published this month in The Journal of Physiology. http://medicalxpress.com/news/2012-08-doctors-lack-medical-condition-mayo.html Health Mon, 13 Aug 2012 15:45:23 EST news264091400 Researchers at the Mayo Clinic say a common condition called leukoaraiosis, made up of tiny areas in the brain that have been deprived of oxygen and appear as bright white dots on MRI scans, is not a harmless part of the aging process, but rather a disease that alters brain function in the elderly.
