BY UNIVERSITY OF BATH: Scientists have created a non-invasive, adhesive patch, which promises the measurement of glucose levels through the skin without a finger-prick blood test, potentially removing the need for millions of diabetics to frequently carry out the painful and unpopular tests.
The patch does not pierce the skin, instead it draws glucose out from fluid between cells across hair follicles, which are individually accessed via an array of miniature sensors using a small electric current. The glucose collects in tiny reservoirs and is measured. Readings can be taken every 10 to 15 minutes over several hours. (read more)
BY HEALTHDAY NEWS: Eating pecans every day for 4 weeks improves certain markers of cardiometabolic disease risk, according to a study published online March 11 in Nutrients.
Diane L. McKay, PhD, from Tufts University in Boston, and colleagues compared the effects of a pecan-rich diet with an isocaloric control diet similar in total fat and fiber content, but absent nuts, on biomarkers related to cardiovascular disease and type 2 diabetes risk. Study participants were healthy middle-aged and older adults who were overweight or obese with central adiposity. (read more)
BY HONOR WHITEMAN In a study of postmenopausal mice and human cells, researchers found that estrogen targets specific cells in the pancreas and the gut to increase tolerance to glucose.
This is associated with a lower risk of type 2 diabetes.
Study leader Jacques Philippe, who is a diabetes specialist currently working at the University of Geneva’s Faculty of Medicine in Switzerland, and colleagues recently reported their results in the journal JCI Insight. (read more)
BY SARINA GLEASON: A new study finds that a particular type of lipid, or fat—thought to only exist in the skin—lives in your eye and might play a major role in deterring the eye disease diabetic retinopathy.
One of the most disabling complications of diabetes, diabetic retinopathy is the leading cause of new cases of vision loss among adults.
“Our study presents an unexpected finding that the connections between cells in the retinal blood vessels contain unusual, long-chain lipids that may keep vessels from leaking, possibly preventing diabetic retinopathy from occurring,” says Julia Busik, lead author of the study in the journal Diabetes and a physiology professor at Michigan State University.

BY UNIVERSITY OF QUEENSLAND: University of Queensland researchers have found a way to identify infants who will go on to develop type 1 diabetes.
UQ Diamantina Institute researcher Professor Ranjeny Thomas said the discovery would lead to the development of better screening tests to identify children at highest risk.
“Most children diagnosed with type 1 diabetes do not have a family history, hence population screening could reduce life threatening complications before diagnosis,” Professor Thomas said.
“By looking at a child’s gene activation pattern early in life, we are able to identify those who will progress to develop antibodies.
“Once they have two antibodies, it’s highly likely they will go on to develop type 1 diabetes. (read more)
