Relaxed Glycemic Control and the Risk of Infections in Older Adults with Type 2 Diabetes

Older adults with poorly controlled type 2 diabetes (T2D) have a higher risk of infection than patients with good glycemic control. However tight glycemic control (e.g., A1C under 7%) in older adults has other risks. In a longitudinal cohort of T2D patien...

Health Economic Analysis of Automated Insulin Delivery Systems

Safely administering insulin to manage blood glucose is challenging for people with type 1 diabetes (T1D). Artificial pancreas or automated insulin delivery (AID) systems mimic pancreatic function by measuring blood glucose (using real-time continuous glu...
