This study looks at how well people with type 1 diabetes follow the Mediterranean diet after starting the Minimed 780G insulin pump, and whether that affects their blood sugar levels and insulin use. About 240 participants aged 7 and older will be observed for 12 months. The goal…

This study looks at how controlling blood sugar and using a GLP-1 drug (liraglutide) changes the way the pancreas works in people with type 1 or type 2 diabetes. Researchers will measure hormone levels before and after treatment. The goal is to understand how these treatments aff…

This study looks at how blood sugar levels change during exercise in healthy adults and those with type 1 diabetes. Participants will cycle after a standard breakfast, and their glucose will be tracked with a continuous monitor and finger-prick tests. The goal is to see if the bo…

This early-phase study is testing whether the antidepressant fluoxetine (Prozac) and/or the hormone DHEA can improve the body's ability to defend against low blood sugar in people with type 1 diabetes. About 60 adults will take the drugs or a placebo for 8 weeks, then undergo two…

The SMILE study is tracking 10,000 adults aged 18 and older to see how sarcopenia (age-related muscle loss) and metabolic diseases like diabetes influence overall health and lifespan. Researchers will collect data from medical records, tests, and surveys over time. This is an obs…

This study examines whether using advanced automated insulin pumps soon after diagnosis can protect brain growth and thinking skills in children aged 5-7 with type 1 diabetes. Researchers will compare brain scans and cognitive tests over 18 months between children using standard …

This observational study is looking at how diet, gut bacteria, and genetics influence blood sugar spikes after meals in people with type 1 diabetes. Researchers will track 200 participants using continuous glucose monitors, food diaries, and stool samples. The goal is to find pat…

This study looks at whether entering fake carbohydrates into the MiniMed 780G insulin pump improves blood sugar control in children and teens with type 1 diabetes. Forty participants aged 7-18 will try two weeks with fake carbs and two weeks without, and their glucose levels will…

This study looks at why diabetes devices like insulin pumps and continuous glucose monitors can cause skin irritation, eczema, or fatty lumps. Researchers will use non-invasive tools to measure skin health in 150 people with type 1 diabetes. The goal is to find ways to prevent th…

This study is collecting blood, urine, and stool samples from 500 children with autoimmune diseases and healthy controls. Researchers will analyze these samples to find molecular patterns that could help diagnose these conditions and guide treatment decisions. The goal is to crea…

This study looks at how the time of day (circadian rhythm) affects blood sugar levels during different types of exercise in teenagers with type 1 diabetes. Researchers will have 18 teens do continuous and intermittent exercise on a stationary bike at different times. They will tr…

This study follows 100 children under 18 who are already on a ketogenic diet for conditions like drug-resistant epilepsy, autism, chronic migraine, or brain tumors. Researchers want to see if the diet supports healthy growth, improves symptoms, and boosts quality of life. The die…

This study is testing whether a continuous glucose monitor (CGM) can predict blood sugar problems in people who are at risk for type 1 diabetes but have no symptoms. Researchers will follow 75 people aged 5 to 39 who have diabetes-related autoantibodies. They will compare CGM dat…
