Filter by:The primary goal of the study is to determine whether insufficient sleep is associated with poor glycemic control in type 1 diabetic children. Secondary goals aim to determine whether salivary amylase could be an easily accessible and non-invasive biomarker of sleep loss and somnolence, and whether insufficient sleep is linked to body composition. Sleep characteristics, glycemic control, salivary amylase and body composition will be assessed 3 times, at 3-4 months intervals, in 82 type 1 diabetic children.
Current intensive insulin therapy in T1D involves prandial insulin boluses depending on the carbohydrate content of each ingested meal. Carbohydrate content of ingested meals is the main determinant of post-meal glucose excursion. Therefore, accurate carbohydrate counting is a critical aspect of managing postprandial blood glucose levels in type 1 diabetes in order to avoid too much or too little insulin resulting in hypoglycemia and hyperglycemia, respectively. Precision of carbohydrate counting is associated with better glycemic control. However, accurate carbohydrate counting is a challenging task for many patients with type 1 diabetes. Recent developments of continuous glucose sensors and insulin infusion pumps have motivated the research toward "closed-loop'' strategies to regulate glucose levels in patients with type 1 diabetes. In a closed-loop strategy, the pump insulin infusion rate is altered based on a computer generated recommendation that rely on continuous glucose sensor readings. A dual-hormone closed-loop strategy has also been recently proposed to regulate glucose levels. In a dual-hormone strategy, subcutaneous insulin delivery is accompanied by subcutaneous glucagon infusion. Postprandial meal glucose control with closed-loop strategy still needs some improvements. The objective of this study is to test in outpatient unrestricted settings whether, in the context of closed-loop strategy, conventional meal carbohydrate counting could be reduced to a simplified qualitative meal size estimation without a significant degradation in overall glycemic control in children and adult patients with type 1 diabetes. The investigators hypothesize that 1) dual-hormone closed-loop strategy with qualitative meal size estimation is equivalent to dual-hormone closed-loop strategy with CHO counting in terms of mean glucose; 2) single-hormone closed-loop strategy with qualitative meal size estimation is equivalent to single-hormone closed-loop strategy with CHO counting in terms of mean glucose;
Closed-loop strategy is composed of three components: glucose sensor to read glucose levels, insulin pump to infuse insulin and a dosing mathematical algorithm to decide on the required insulin dosages based on the sensor's readings. The main objective of this project is to compare the efficacy of single-hormone closed-loop strategy and sensor-augmented pump therapy to regulate glucose levels in outpatient settings for 5 consecutive days in adults with type 1 diabetes. The investigators hypothesized that single-hormone closed-loop strategy will increase the time spent in the target range compared to sensor-augmented pump therapy.
To determine the safety, feasibility and efficacy of the Multiple Model Probabilistic Predictive Control / Diabetes Assistant (MMPPC/DiAS) system in full day and night closed-loop control in adolescents and adults with type 1 diabetes. This will be addressed in two parts. There will be an initial 36 hour inpatient study with hourly plasma glucose monitoring and scheduled exercise and meals. If the system is shown to be safe, feasible and effective, the study will proceed to supervised hotel studies with remote monitoring to test system use over 3 days/2 nights.
This study is designed to examine the value of infusing BHB in type 1 diabetic subjects during experimentally induced hypoglycemic episode in conjunction with testing of cognitive function. This will lay the basis for subsequent trials exploring the novel use of therapeutic doses of oral ketone formulations that are currently under commercial development, which could serve as adjunct therapies to protect the brain from hypoglycemia in type 1 diabetic subjects experiencing recurrent hypoglycemia.
The family of inflammatory/autoimmune systemic diseases (IAD) form a continuum from pure inflammatory diseases to pure autoimmune diseases, encompassing a large panel of inflammatory diseases with some autoimmune components, and vice versa. Cross phenotyping of patients with IAD should be heuristic and help revise the nosography and the understanding of these diseases.
Patients meeting the study entry criteria will receive 1-3 infusion(s) of in vitro cultured islets. Patients will receive three times a week AAT infusions in the peri-transplant period for three weeks.
This study is a single-arm, multi-center, Home and Hotel Clinical Investigation in subjects with type 1 diabetes on insulin pump therapy. The purpose of this study is to demonstrate that the closed loop algorithm that is built into the 670G insulin pump is safe as part of the overall system.
In this study, the investigators hypothesize that the addition of antioxidant BMX-010 to perfusion solution, digestion solution and culture medium during islet isolation process, can lead to greater preservation of islet mass and metabolic function, such as improved islet yield, viability, and functional potency. This pilot study will involve up to 10 participants from the islet transplant waiting list at the Clinical Islet Transplant Program. All participants will receive islets isolated with the medication BMX-010. This is to assess the primary safety of BMX-010 on pancreata and islets. BMX-010 will be used only in the islet isolation process, and will not be given to participants as medication.
The purpose of this study is to demonstrate the performance of the Harmony 1 Sensor in subjects age 2 - 75 years
