New Contact Lens Could Ease Blindness Caused by Diabetes

BY GINGER VIERIA: If you’re living with type 1 or type 2 diabetes, you undergo an eye exam every year to detect signs of retina damage due to high and fluctuating blood sugar levels.

For many, even reasonably good diabetes management can’t prevent ongoing damage to the blood vessels in the eye. In the most advanced (yet quite common) cases, blindness is a devastating reality.The future of diabetes technology looks brighter, though, with a “glowing” contact lens specifically designed to prevent further damage to the blood vessels of your retina.The lenses are worn only at night and researchers say they could offer a long-term solution to a long-term problem. (read more)

Diabetes Risk Elevated in Breast Ca Survivors Treated with Hormone Tx

BY PAM HARRISON: Breast cancer survivors who were treated with either tamoxifen or an aromatase inhibitor (AI) for hormone receptor-positive breast cancer were significantly more likely to develop diabetes during a median follow-up of 5.9 years compared with women who did not have hormonal therapy, a case-control study found.

In a study of 2,246 female breast cancer patients with no history of diabetes before their diagnosis or in the first year thereafter, Israeli investigators found that hormone therapy increased the risk of diabetes by almost 2.5 times on multivariable-adjusted analysis compared with those who did not have hormone therapy, according to Rola Hamood, MD, of the University of Haifa, and colleagues. (read more)

Carbohydrates And Diabetes: Benefits And Side-Effects

BY DLIFE: A healthy, balanced diet includes the proper concentration of fats, carbohydrates, and protein. Increasing or reducing any of the nutrients may not be good for the body. For people with diabetes, a diet high in carbohydrates can be either beneficial or dangerous, depending on the type of diabetes.

When you eat food that contains carbohydrates, your digestive system will break down the digestive part into sugar, and this enters the blood. As the blood sugar level rises, the pancreas will produce insulin, a hormone which enables cells to use blood sugar for storage or energy. (read more)


Are people with diabetes, obesity predisposed to stress?

BY MARIA COHUT: According to Auriel Willette, Tovah Wolf, and others at the University of Wisconsin-Madison and Iowa State University in Ames, the answer to this is “yes.”

Previous studies have revealed that people who live with both type 2 diabetes and obesity seem to be more predisposed to mood disorders such as depression.

The scientists involved in the new study thought that this raised emotional response to stressors may have to do with insulin resistance, which sets up the context for an increased negative emotional response. (read more)

Diabetes-associated pain linked to disrupted insulin signalling

BY ANAHAD O’CONNOR: The chronic pain experienced by a number of patients with diabetes has widely been assumed to originate from damage to blood vessels or to local tissue surrounding neurons caused by high blood-sugar levels. However, a new study reports that in fruit flies, this pain hypersensitivity results instead from disrupted insulin signalling in pain sensory neurons.

Chronic pain is a frequent complication of diabetes, with surveys reporting rates of 20% to over 60% of individuals with diabetes also having to deal with pain hypersensitivity, severe pain and/or numbness that makes self-management of their disease more difficult. The symptoms usually start with a tingling sensation at the distal extremities, spreading to cover all of the hands and lower legs as the severity of pain increases. (read more)
