Chairside Diabetes Screening: A Survey of Dental Providers at the Largest Municipal Healthcare System in the United States.

Purpose: To assess the knowledge and attitudes of dentists at the largest municipal healthcare system in the United States with regard to point-of-care chairside diabetes testing in the dental clinic.

Materials And Methods: A 29-item survey was designed in a web-based platform (Survey Monkey) and distributed in November 2020 to 264 dental providers (attending dentists and residents) within eleven dental departments of the New York City Health + Hospitals municipal healthcare system. The questionnaire included sections on demographics, current practices, level of diabetes training, scope of practice, and attitudes regarding chairside diabetes testing.

Activation of local inhibitory circuits in the dentate gyrus by adult-born neurons.

Robust incorporation of new principal cells into pre-existing circuitry in the adult mammalian brain is unique to the hippocampal dentate gyrus (DG). We asked if adult-born granule cells (GCs) might act to regulate processing within the DG by modulating the substantially more abundant mature GCs. Optogenetic stimulation of a cohort of young adult-born GCs (0 to 7 weeks post-mitosis) revealed that these cells activate local GABAergic interneurons to evoke strong inhibitory input to mature GCs.
