    In a new clinical trial to observe a new method of injecting islet cells into a patient with Type 1 diabetes, doctors from the University of Miamis Diabetes Research Institute have confirmed that their first trial patient no longer needs insulin therapy. Wendy Peacock, their first patient, has been giving herself insulin injections and following a strict daily schedule to take care of her diabetes since she was diagnosed with Type 1 diabetes at 17. Now 43, Peacock has undergone the surgery in this new trial and no longer needs injections because her body is producing insulin naturally. Since the...

    The scientific community is not immune to politics, bias, and self-interest.The headline looks like a hoax saturated fat does not cause heart disease but its real. This news is more than just another example of changing health guidelines. Its a cautionary tale about trusting the scientific consensus. For more than 50 years, the best scientific minds in America assured us that saturated fat was the enemy. Animal fat, we were instructed, was the chief culprit in causing obesity, Type II diabetes, and heart disease. Throughout my adult life, I have conscientiously followed the guidelines dispensed by the health...
  • Obesity is Inflammatory Disease, Rat Study Shows

    Scientists led by Dr David Fairlie from the University of Queensland, Australia, have found abnormal amounts of an inflammatory protein called PAR2 in the fat tissues of overweight and obese rats and humans. PAR2 is also increased on the surfaces of human immune cells by common fatty acids in the diet. When obese rats on a diet high in sugar and fat were given a new oral drug that binds to PAR2, the inflammation-causing properties of this protein were blocked, as were other effects of the high-fat and high-sugar diet, including obesity itself.Zucker Rat, a pet rat that has developed...

    The rates of five serious complications from diabetes -- heart disease, stroke, kidney disease, amputations and death -- have all dropped dramatically since 1990, a new U.S. government study shows. Heart attack rates have decreased nearly 70 percent in people with diabetes. Stroke rates have dropped by more than 50 percent, as have lower extremity amputations. Deaths from high blood sugar crises have fallen nearly 65 percent, and the risk of end-stage kidney disease is down 28 percent, according to the study. The biggest declines in diabetes-related complications have occurred for heart attack and stroke, especially among people aged 75...

    "We find that there is a peptide hormone in the gut called GLP1 that increases the secretion of insulin only when the blood glucose is high. This effectively eliminates the risk of hypoglycemic shock. Another advantage is that GLP1 administration has been found to stimulate weight-loss. The hormone offers the promise of revolutionising the treatment of Type II diabetes and reduce obesity," he said.

    Alzheimers and diabetes may be the same disease, scientists claim. They have uncovered evidence that the debilitating form of dementia may be late stages of type 2 diabetes. The discovery would explain why nearly three quarters of patients with this form of diabetes go on to develop Alzheimers. Researchers from Albany University, New York State, believe the excess insulin they produce gets into the brain and disrupts key chemicals. Eventually masses of amyloid proteinswhich poison brain cellsare created because of the excess which leads to Alzheimers, they say.
  • News In Brief: Fructose may be key to weight gain

    Mice that could not make or metabolize the sugar gained less than normal mice. Mice lacking the ability to metabolize fructose dont gain nearly as much weight as normal mice do, researchers report September 10 in Nature Communications. Fructose, which some people blame for the obesity epidemic and its related health crises (SN: 6/1/13, p. 22), shows up in high-fructose corn syrup and in table sugar, or sucrose. The body also makes home-grown fructose by modifying glucose in a process involving an enzyme called aldose reductase.

    Researchers at the University of Colorado School of Medicine reported today that the cause of obesity and insulin resistance may be tied to the fructose your body makes in addition to the fructose you eat. In recent years the role of added sweeteners, such as high fructose corn syrup and table sugar (sucrose), has taken center stage as risk factors for obesity and insulin resistance. Numerous studies suggest that the risk from added sugars may be due to the fructose content. But in the study published in the Sept. 10 edition of Nature Communications, the team led by researchers at...

    Exercise promotes health, reducing most peoples risks of developing diabetes and growing obese. But just how, at a cellular level, exercise performs this beneficial magic what physiological steps are involved and in what order remains mysterious to a surprising degree. Several striking new studies, however, provide some clarity by showing that exercise seems able to drastically alter how genes operate. Genes are, of course, not static. They turn on or off, depending on what biochemical signals they receive from elsewhere in the body. When they are turned on, genes express various proteins that, in turn, prompt a range...

    Diabetic rats control blood glucose better after weight-loss surgery. A procedure increasingly used to treat obesity by reducing the size of the stomach also reprogrammes the intestines, making them burn sugar faster, a study in diabetic and obese rats has shown. If the results, published today in Science1, hold true in humans, they could explain how gastric bypass surgery improves sugar control in people with diabetes. They could also lead to less invasive ways to produce the same effects. This opens up the idea that we could take the most effective therapy we have for obesity and diabetes and come...

    Like the sun, insulin levels rise and fall in a daily rhythm. Disrupting that cycle may contribute to obesity and diabetes, a new study suggests. Many body systems follow a daily clock known as a circadian rhythm. Body temperature, blood pressure and the release of many hormones are on circadian timers. But until now, no one had shown that insulin a hormone that helps control how the body uses sugars for energy also has a daily cycle. Working with mice, researchers at Vanderbilt University in Nashville have found that rodents are more sensitive to insulins effects at certain...

Yet circadian rhythms affect our bodies not just on a global scale, but at the level of individual organs, and even genes. Now, scientists at the Salk Institute have determined the specific genetic switches that sync liver activity to the circadian cycle. Their finding gives further insight into the mechanisms behind...

    Weight loss surgery, which in recent years has been seen as an increasingly attractive option for treating Type 2 diabetes, may not be as effective against the disease as it was initially thought to be, according to a new report. The study found that many obese Type 2 diabetics who undergo gastric bypass surgery do not experience a remission of their disease, and of those that do, about a third redevelop diabetes within five years of their operation. The findings contrast with the growing perception that surgery is essentially a cure for Type II diabetes. Earlier this year, two widely...

    Countries using high-fructose corn syrup have diabetes rates 20 percent higher than countries that do not, a new international analysis finds. High-fructose corn syrup (HFCS) in national food supplies around the world might help explain the rising rates of type 2 diabetes around the world, researchers at the University of Southern California and the University of Oxford report in the journal Global Public Health. After studying 42 countries, researchers found that those that use HFCS in their food supply had a 20 percent higher prevalence of diabetes than those that did not use HFCS, suggesting an association with diabetes independent...

    Scientists at Indiana University and international collaborators have found a way to link two hormones into a single molecule, producing a more effective therapy with fewer side effects for potential use as treatment for obesity and related medical conditions. The studies were carried out in the laboratories of Richard DiMarchi, the Standiford H. Cox Distinguished Professor of Chemistry and the Linda & Jack Gill Chair in Biomolecular Sciences in the IU Bloomington College of Arts and Sciences, and of Matthias Tschp, professor of medicine and director of the Institute of Diabetes and Obesity, Helmholtz Center Munich, Germany. Results were published...

    THE HYPOTHESIS In Type 2 diabetes, insulin-producing cells revert to an earlier developmental state. THE INVESTIGATORS Chutima Talchai and Dr. Domenico Accili, Columbia University... The hormone insulin helps shuttle glucose, or blood sugar, from the bloodstream into individual cells to be used as energy. But the body can become resistant to insulin, and the beta cells of the pancreas, which produce the hormone, must work harder to compensate. Eventually, the thinking goes, they lose the ability to keep up. We used to say that the beta cells poop out, said Alan Saltiel, director of the Life Sciences Institute at the...

    Shedding pounds may be a better way to promote cardiovascular health than avoiding the saltshakerThe latest news reports about salt are enough to make a parent ponder a household ban on pizza and cold cuts. A study published last week in Pediatrics found that children eat, on average, 3.4 grams of sodium daily—more than twice the amount recommended for adults by the Institute of Medicine (IOM). News outlets, including the Associated Press and USA Today, explained that, according to the study, the quarter of American kids who eat the most sodium are twice to three times as likely to develop...
  • Turning White Fat Into Energy-Burning Brown Fat: Hope for New Obesity and Diabetes Treatments

    Columbia University Medical Center (CUMC) researchers have identified a mechanism that can give energy-storing white fat some of the beneficial characteristics of energy-burning brown fat. The findings, based on studies of mice and of human fat tissue, could lead to new strategies for treating obesity and type 2 diabetes. The study was published August 2 in the online edition of the journal Cell. Humans have two types of fat tissue: white fat, which stores excess energy in the form of triglycerides, and brown fat, which is highly efficient at dissipating stored energy as heat. Newborns have a relative abundance of...
  • New Brain Target for Appetite Control Identified

    Finding raises hopes for new anti-obesity medications New York, NY (June 7, 2012) Researchers at Columbia University Medical Center (CUMC) have identified a brain receptor that appears to play a central role in regulating appetite. The findings, published today in the online edition of Cell, could lead to new drugs for preventing or treating obesity. Weve identified a receptor that is intimately involved in regulating food intake, said study leader Domenico Accili, MD, professor of Medicine at CUMC. What is especially encouraging is that this receptor belongs to a class of receptors that turn out to be good targets...

    CAPE GIRARDEAU, MO (KFVS) - Recent data shows a shocking jump in youth diabetes. A new study in the Journal of the American Academy of Pediatrics said 1 out of 4 youth in the U.S. is diabetic or pre-diabetic. The study looked at kids under 20 years old. It showed between 2000 and 2008, the percentage of teens with pre-diabetes and diabetes jumped from nine to 23 percent. Local Diabetes Educator Janet Stewart at Southeast Health said in the past decade she's seen the number of kids with Type 1 or Type 2 diabetes jump almost 30 percent. She said...

    Obesity and the form of diabetes linked to it are taking an even worse toll on America’s youths than medical experts had realized. As obesity rates in children have climbed, so has the incidence of Type 2 diabetes, and a new study adds another worry: the disease progresses more rapidly in children than in adults and is harder to treat. “It’s frightening how severe this metabolic disease is in children,” said Dr. David M. Nathan, an author of the study and director of the diabetes center at Massachusetts General Hospital. “It’s really got a hold on them, and it’s hard...
