BY LIAM DAVENPORT: An after-hours group-based nutrition class given alongside medication significantly improved weight, glycemic control, and cholesterol levels among patients with type 2 diabetes, regardless of which diet plan they were assigned to, results of a US randomized controlled study suggest.
The study of more than 40 patients with type 2 diabetes indicated that, after 20 weeks of following a vegan or portion-controlled diet supported by weekly group nutrition classes, patients had significant reductions in HbA1c and low-density lipoprotein cholesterol (LDL-C), as well as body mass index (BMI).

BY RICHARD BLACKBURN: One such plant used throughout history was chamomile, which gives a bright yellow colour on wool, cotton and other natural fibres. There is evidence of its use in Europe and Asia to dye textiles dating back many hundreds of years. We identified the colourants and other natural components present in several species of chamomile in our attempts to understand their coloration properties and their identification in historical textiles, in the process significantly developing our knowledge of their complex chemistry.
This would have been interesting from a pure conservation and dye chemistry perspective. But then members of our team had a chat with another research group, led by Professor Gary Williamson in the School of Food Science and Nutrition, and it became apparent that we had a mutual interest in the chemistry of chamomile.

BY KRISTIN SAMUELSON: Screening patients for diabetes based solely on their age and weight – a recommendation from a leading medical expert group – could miss more than half of high-risk patients, according to a new Northwestern Medicine study of a nationwide sample. These limited screening criteria also missed more racial and ethnic minorities, most notably Asians.
Failing to screen high-risk adults could lead to delayed treatments to prevent type 2 diabetes or manage the condition for those who already have it, possibly contributing to a worsening of the diabetes epidemic. Prediabetes and diabetes affect half of U.S. adults with an estimated cost of $327 billion per year. (read more)
BY SCIENCE DAILY: Continuous glucose monitors (CGM) offer significant, daily benefits to people with type 1 diabetes, providing near-real time measurements of blood sugar levels, but they can be expensive. A new study by researchers from the University of Chicago Medicine, based on a 6-month clinical trial, finds that use of a CGM is cost-effective for adult patients with type 1 diabetes when compared to daily use of test strips. The results are well within the thresholds normally used by insurance plans to cover medical devices. During the trial, CGMs improved overall blood glucose control for the study group and reduced hypoglycemia, or low blood sugar episodes.
The study, published April 12, 2018 in Diabetes Care, a journal from the American Diabetes Association, also simulated the costs and health effects of CGM use over the expected lifetime of patients. It showed that CGMs also increased quality of life by extending the amount of time patients enjoy relatively good health, free of complications. (read more)
BY TORI RODRIGUEZ: Broadly, GI disturbances in diabetes “can be regarded as the outcome of a disordered gut-brain axis,” according to a new review published in Diabetes Care. “Potential pathogenic factors include autonomic (vagal and myenteric) and peripheral neuropathy, structural and functional central nervous system (CNS) changes (diabetic encephalopathy), acute and chronic dysglycemia, psychological dysfunction, and pharmacotherapy.”
Validated assessments should be used to assess GI symptoms in patients with diabetes, such as the Bowel Disease Questionnaire (BDQ), the Patient Assessment of Upper Gastrointestinal Symptom Severity Index (PAGI-SYM), the Diabetes Bowel Symptom Questionnaire (DBSQ), and the Gastroparesis Cardinal Symptom Index daily diary. Diagnostic and treatment approaches for these symptoms are often similar to those used in patients without diabetes. (read more)
