Exercise-induced Glycemic Variations and Hybrid Closed-loop Systems
Type 1 DiabetesExerciseType 1 diabetes is characterized by high risk of hypoglycemia and associated fear of hypoglycemia. Hypoglycemia risk is higher during and after physical activity, especially aerobic activity of long duration. Fear of hypoglycemia can result in avoidance of exercise or overcompensatory eating, both related to worse metabolic control and increased cardiometabolic risk. Hybrid closed-loop (HCL)systems have significantly improved risk of hypoglycemia. They also offer the possibility to set a temporary target for physical activity, further reducing the risk of hypoglycemia during physical activity. Although temporary target seems to work rather well with moderate-intensity aerobic exercise, little data is available for other types of exercise, like resistance exercise, high-intensity interval exercise, combined modalities of exercise, in which the temporary target seems to perform less well. The present study aims to test the performance of current HCL systems under different exercise conditions and evaluate the relationship between different exercise variables (recorded during exercise), physical activity variables (measured by accelerometry) and glycemic variations in HCL system users.

Adapting Diabetes Treatment Expert Systems to Patient in Type 1 Diabetes
Diabetes MellitusType 1This study is evaluate the superior efficacy of a Continuous Glucose Monitor (CGM)-based advisory system in Type 1 Diabetes Mellitus (T1DM), as compared to Sensor Augmented Mode (SAM) therapy, and with characterizing the impact of psycho-behavioral factors on system performance, which will enable system individualization and lead to automated adaptation of advice delivery to optimize glycemic control and reduce the system's psychological impact.
Glucagon-like Peptide-1 in Type 1 Diabetes
Type1 Diabetes MellitusThe hypotheses to be tested in this application is: GLP-1 will acutely protect arterial endothelial function and reduce pro-atherothrombotic and pro-coagulant effects of repeated hypoglycemia in T1DM.
Effects of GRA in Patients With Type 1
Type 1 DiabetesThis study will examine the effects a Glucagon Receptor Antagonist (GRA), has on Insulin Sensitivity, Cardiovascular risks (CVD), and Ketone body formation in participants with Type 1 diabetes. The participants will complete blood tests, tests to measure energy expenditure, CVD risks, and insulin resistance. These tests will be performed prior to start of treatment and again after 12-weeks of treatment with the GRA (called REMD-477).
Use of CGM in Kidney Transplant Recipients
Kidney Transplant; ComplicationsDiabetes Mellitus2 moreThe investigators want to study the impact CGM (continuous glucose monitoring) has on patients glycemic control as determined by time in range (TIR 70-180 mg/dL) in the Diabetic Kidney Transplant population.
Feasibility and Effectiveness of Real-time, Remote Continuous Glucose Monitoring in Adolescents...
Diabetes MellitusType 12 moreAdolescents with Type 1 Diabetes (age 13-18 years, T1D duration >6 months managed on insulin) and poor glycemic control will wear a blinded CGM to obtain baseline data. After assuring adherence to CGM wear, participants will receive a non-blinded CGM and will share their blood glucose levels with the study team. Clinical personnel will remotely monitor patients in real-time for 3 months and communicate regularly over secure text messaging with participants and their parents. Following active remote monitoring, the participants will wear a non-blinded CGM for 3 months. Primary outcome assessment will be the change in HbA1c after 3 months of real-time remote continuous glucose monitoring.
Effects of Ketosis on Brain Function in Patients With T1DM
Type1diabetesThe scientific goal of this study is to examine the effects of a ketogenic diet on hypoglycemia tolerance and brain function in people with type 1 diabetes mellitus (T1D) and to clarify the mechanistic role of ketones in this process. Glycemic management of T1D is typified by alternating periods of hyper- and hypo-glycemia. Because brain metabolism under usual conditions depends on glucose, acute hypoglycemia leads to immediate complications including impaired cognitive function and a counter-regulatory hormone response. Recurrent hypoglycemia is associated with functional and structural changes in the brain and contributes to the cognitive decline observed in individuals with diabetes. The state of nutritional ketosis (as it occurs during fasting or when following a ketogenic [very low carbohydrate] diet) may protect against these acute and chronic complications. As the body relies on fat metabolism, ketone bodies build up and provide an alternative fuel for the brain. Studies during hypoglycemia have shown better cognitive function and less hypoglycemia symptoms in the setting of nutritional ketosis or with ketone administration. This physiological benefit may have special relevance for people with T1D who experience hypoglycemia frequently. To date, no mechanistic studies have examined brain effects of nutritional ketosis in T1D; nor have any trials explored the potential relevance of this for diabetes care.
Effectiveness of a Transition Program for Adolescents With Type 1 Diabetes in the Transition to...
Type 1 DiabetesThe transfer of young people with type 1 diabetes (T1D) to adult care occurs during a critical period of life, while many young people with T1D have unsatisfactory glycemic control. The preparation to take over responsibility for their health and self-care as well as increasing their participation in care are important aspects for strengthening people's own ability, an important component of person-centered care. STEPSTONES-DIAB aims to evaluate the effectiveness of a person-centred transition program for adolescents with T1D to empower them to become active partners in their care. The study is conducted at two hospitals in Stockholm, Sweden where 140 patients will be randomized to either a structured, person-centered transition program over a 2.5 -year period or to usual care. Outcome measures is empowerment, participation and responsibility in care, health status, glycemic control as well as the participants' experiences of care during transfer.
Diabetes Learning in Virtual Environments Just in Time for Community Reentry
Diabetes MellitusType 12 moreThe proposed study will use a randomized clinical trial design with non-equivalent control group and longitudinal design to evaluate the feasibility, acceptability, and preliminary effects of the Diabetes LIVE JustICE application. The design will incorporate repeated measures at 0, 6, and 12 weeks. Outcome variables will include recruitment assessments, participation, engagement, user experience, and measures proximally related to behavior change - e.g., diabetes knowledge, diabetes-related distress, diabetes self-care, and social support and clinical outcomes -e.g., glycemic control. Focus group interviewing will be conducted to evaluate acceptability among intervention group participants.
