Data showed people on a gluten-free diet had urinary concentrations of arsenic that were almost twice as high as people who were not on the diet, according to a study published in Epidemiology. Researchers said people on a gluten-free diet also had higher blood levels of inorganic mercury.
Adults with type 1 diabetes in the continuous glucose monitoring plus blood glucose monitoring group had 65% of the mean time spent with blood glucose levels at 70 to 180 mg/dL at 26 weeks, compared with 63% in the CGM-only group, according to a study in Diabetes Care. Researchers used a cohort of 226 patients and found that one severe hypoglycemic event occurred in the CGM+BGM group, while none occurred in the CGM-only group.
A study in The New England Journal of Medicine showed that patients with newly diagnosed type 1 diabetes maintained the natural production of their insulin levels after receiving injections of the GAD-alum drug, developed based on the GAD65 protein, and vitamin D supplements. Swedish researchers evaluated six diabetes patients ages 20 to 22 and plan to continue the study and expand it to more participants.
Researchers found that older type 2 diabetes patients on long-term metformin therapy had significantly lower mean vitamin B12 concentration, compared with those without diabetes who were not on metformin. The findings in the Journal of the American Geriatrics Society, based on 16,945 veterans with and without diabetes, ages 50 or older, revealed that metformin users were two to three times more likely not to receive testing for vitamin B12 status, depending on their age.

A study that included adults ages 20 to 74 showed those with higher levels of active vitamin D had more lean muscle mass and bulk. Researchers wrote in PLOS ONE that earlier research found inactive vitamin D was associated with a lack of muscle.
Nutrition experts say a common misconception that can counter fitness gains from exercise is that cutting back on carbohydrates aids weight loss, because the body uses carbs as energy during a workout. Registered dietitian nutritionist Victoria Shanta Retelny says while many people try to eat right after a workout, the post-exercise anabolic window, when protein intake helps build muscle, is actually as long as several hours.
A coalition of 45 US school districts that make up the nonprofit group School Food Focus has created a new industry standard for poultry used in student meals.

New language in the national coverage determination for Medicare implemented in 2013, which allowed PET radiopharmaceutical manufacturers to seek coverage from local Medicare administrative contractors, has accelerated approval and boosted access to oncologic radiotracers C-11 choline, Netspot and Axumin, and the CMS' development of new A-codes reduces inappropriate payer denials and coding burdens, writes Terri Wilson of Blue Earth Diagnostics. However, the CMS should address payment rate challenges under the Medicare Outpatient Prospective Payment System, while manufacturers and imaging providers should collaborate to ensure all commercial payers provide coverage, Wilson writes.
