Abstract:
The Automated Insulin Delivery in Elderly with Type 1 Diabetes (AIDE T1D) trial randomized 82 adults ≥65 years with type 1 diabetes (T1D) to hybrid closed loop (HCL), predictive low glucose suspend (PLGS), and sensor-augmented pump (SAP) therapy in a randomized crossover trial. Seventy-five of the 78 completers joined an extension phase in which they were offered the pump mode of their choice for an additional 3 months. Mean age was 71 ± 4 years (range 65-86 years) and mean duration of T1D was 42 ± 17 years (range 1-68 years). Use of HCL was selected by 91%, PLGS by 8%, and continuous glucose monitoring with injections by 1%. For participants selecting HCL, time-in-range 70-180 mg/dL was similar in the randomized controlled trial and extension phase (mean 75% ± 10%). One severe hypoglycemic event was reported. HCL was preferred over PLGS or SAP and remained effective in older adults with T1D. Clinical Trial Registration: NCT04016662.

Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
