Diabetes is an independent predictor of acute organ failure and subsequent death
Diabetes puts people at risk of developing critical illness and dying early, but obesity without diabetes does not. A study published today in the open access journal Critical Care reveals that individuals suffering from diabetes are three times more at risk of developing critical illness and dying young than individuals who do not have diabetes.

Low testosterone levels associated with increased risk of death in men
Men who have a low testosterone level after age 40 may have a higher risk of death over a four-year period than those with normal levels of the hormone, according to a report in the August 14/28 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. Unlike women undergoing menopause, middle-aged men generally do not experience a dramatic decrease in the production of sex hormones, according to background information in the article. Testosterone levels gradually decline as a man ages, decreasing approximately 1.5 percent per year after age 30. The effects of low testosterone levels include decreased muscle mass and bone density, insulin resistance, decreased sex drive, less energy, irritability and feelings of depression.

Obesity, Diabetes and Infertility: Leptin answers all!
Twelve years ago, scientists discovered leptin—the now-famous hormone that controls appetite, burns calories and performs other crucial physiological activities as well. But the precise mechanism(s) by which leptin carries out these metabolic tasks is still controversial. Now, researchers at the Albert Einstein College of Medicine of Yeshiva University have shown how leptin exerts some of its most important effects.

Infections Link With diabetes
A major study has added weight to the theory that environmental factors such as common infections may be a trigger for diabetes in children and young adults. The study, the biggest of its kind, analysed information from a register of over 4,000 people aged 0-29 years old diagnosed with Type 1 diabetes over a 25-year period. The findings for young adults have not been published before. A quarter of a million people in the UK have Type 1 diabetes, and the number of cases in children is rising by three per cent each year. It develops if the body is unable to produce any insulin and usually appears before the age of 40.

HbA1c Reduction of up to 2.8% with Vildagliptin Combination
Vildagliptin seeking to become a new once-daily oral treatment option for type 2 diabetes, has demonstrated impressive efficacy, especially in patients with poor glycemic control, as well as weight loss benefits in obese patients. The combination of Galvus (Vildagliptin), a member of the DPP-4 inhibitor class, and pioglitazone led to an overall 1.9% reduction in HbA1c (a measure of blood sugar control also known as A1c). Pioglitazone is an insulin sensitizer known as a thiazolidinedione, or TZD. Two-thirds of people (65%) on Galvus and pioglitazone achieved the ADA-defined A1c goal of less than or equal to 7% versus 42% of those who achieved this goal on monotherapy (Galvus 42.5%, pioglitazone 42.9%).

Nerve signals to pancreas after a meal determine blood sugar control
Nerve signals relayed directly to the pancreas after eating a meal play a critical role in normal blood sugar control, according to a report in the June 7, 2006, Cell Metabolism. Therefore, drugs that increase the sensitivity to such signals might offer a new approach to diabetes treatment, the researchers said.

Gene therapy prevents onset of hyperglycemia in diabetes prone mice
Using state-of-the-art gene therapy techniques, University of Pittsburgh investigators have successfully prevented the onset of elevated blood sugar, or hyperglycemia, in diabetes-prone mice by inserting a gene encoding for a cytokine -- a protein that stimulates or inhibits the proliferation or function of immune cells -- into their insulin-producing cells. According to the investigators, these findings, which are being presented at the American Society of Gene Therapy Annual Meeting in Baltimore, May 31 to June 4, have significant implications for the prevention of type 1 diabetes.

Causes of Adverse Reactions to Popular Type 2 Diabetes Drugs Pinpointed
Used by several million people worldwide, rosiglitazone (RSG) is an oral agent that helps patients with type 2 diabetes maintain good blood glucose levels by improving how their bodies use insulin. But RSG, like all the other thiazolidinedione (TZD) drugs that can lower blood glucose levels, can cause fluid retention (edema), a condition that puts patients at greater risk for weight gain, vascular complications and heart failure. Recently, the U.S. Food and Drug Administration and GlaxoSmithKline, which manufactures the drugs, reported cases of new onset or worsening macular edema (an eye disorder that leads to blurred or distorted vision) among patients who took RSG. While reports of these complications remain rare, GlaxoSmithKline has added a warning about the risks to the drugs’ labels.

A gene predisposing to pituitary adenomas identified
A recent Finnish study identifies a low-penetrance gene defect which predisposes carriers to intracranial tumors called pituitary adenomas. In particular individuals carrying the gene defect are susceptible to such tumors which secrete growth hormone. Excess of growth hormone results in conditions called acromegaly and gigantism. Identification of this gene defect using DNA-chip technologies is an example how genetic research can tackle more and more demanding tasks, such as identification of predisposition genes conferring a low absolute but high relative risk. The results are published in the May 26 issue of the journal Science.

Lifestyle interventions needed to halt the increasing incidence of diabetes
More and more Americans are being diagnosed with diabetes. Is this rise in cases due to better testing, a change in diagnostic criteria, a true rise in incidence, or some combination of these and other factors? In a study in the May issue of the American Journal of Preventive Medicine, researchers from the Centers for Disease Control and Prevention examine some of the reasons for this increase. They conclude that obesity is a major factor in this recent increase of newly diagnosed diabetes. Lifestyle interventions that reduce or prevent the prevalence of obesity among persons at risk for diabetes are needed to halt the increasing incidence of this disease.

Hap1 protein links circulating insulin to feeding behavior regulating brain circuits
Researchers have discovered how the protein Hap1, which is abundant in the brain's hypothalamus, serves as the link between circulating insulin in the blood and the neural circuitry that controls feeding behavior in mice. Illumination of the neural pathway used by hormones to regulate appetite and eating behavior could eventually provide new drug targets for treating eating disorders and obesity. The research, reported on-line April 9 in the journal Nature Medicine, will be published in the May 1 print edition.
