Top in endocrinology: Continuous glucose monitoring; genetic testing for hypothyroidism

It remains unclear whether continuous glucose monitoring benefits people without diabetes, researchers reported.

In a recent study, they found a discordance between glucose management indicator (GMI), a metric of continuous glucose monitoring that estimates HbA1c, and laboratory-measured HbA1c.

“Based on the findings from our study, it would not be appropriate to use GMI as a substitute for HbA1c in people without diabetes,” Viral N. Shah, MD, an associate professor of medicine and pediatrics in the adult clinic of the Barbara Davis Center for Diabetes at the University of Colorado Anschutz Medical Campus, told Healio.

It was the top story in endocrinology last week.

The second top story covered a study on the potential of using genetic testing to assist in the diagnosis of congenital hypothyroidism in children. Researchers reported that genetic testing led to a change in diagnosis for 10 of 48 children with congenital hypothyroidism.
