Diabetes Mellitus, Type 1 Diabetes

This study plans to learn more about whether a support program delivered in Spanish or both English and Spanish for bilingual families helps Latino youth with Type 1 Diabetes (T1D) successfully use the Medtronic MiniMed 780G system. The main question it aims to answer is: Does a linguistically and culturally tailored onboarding model for an automated insulin delivery system close the gap in technology adoption and improve health outcomes? Participants will: * Use the Medtronic MiniMed 780G Automated Insulin Delivery system for eight months * Attend one in-person nutrition support and insulin pump start class * Participate in regular virtual check-ins with native Spanish-speaking study team members

This study evaluates the usability of the KOS Argus Continuous Glucose Monitoring (CGM) System, a noninvasive, wrist-worn device that estimates blood glucose levels using light-based sensors and artificial intelligence algorithms. The Argus device does not puncture the skin or require sensor insertions. The study will enroll up to 100 adults with type 1 diabetes, type 2 diabetes, or prediabetes at a single site. Participants will complete a screening visit, followed by a Day 1 in-clinic baseline visit that includes serial venous blood draws approximately every 10 minutes over 6 hours to collect paired reference blood glucose measurements alongside Argus device readings. After the baseline visit, participants will wear the Argus device and a commercially available Dexcom Stelo CGM continuously for 15 days during normal daily activities. The primary objective is to collect paired glucose data to support device development and algorithm training. Participants will not receive glucose readings from the Argus device and will continue their usual diabetes management throughout the study. Secondary objectives include assessing device safety, tolerability, adherence, and operational lifespan over the 15-day wear period.

The goal of this study is to determine whether the Achieving Health in Emerging Adults with Diabetes (AHEAD) Program helps emerging adults with type 1 diabetes improve their blood glucose management during the transition from pediatric to adult care. Participants will be randomized to receive Usual Care or the AHEAD Program, which provides tailored support to emerging adults to build autonomy and competence to facilitate independent diabetes management. Researchers will compare changes in glycemia and participant-reported outcomes between groups.
