Filter by:The purpose of this study is to compare the time spent in glucose target range (4.0-10.0 mmol/L) during exercise and in recovery using three different management strategies for prolonged aerobic exercise: A) carbohydrate dose of 0.3g/kg/hr; B) A 50 percent basal rate reduction, performed 90-minutes in advance of exercise for the duration of the activity; and C) A 50 percent basal rate reduction, performed at exercise onset, with carbohydrate dose of 0.3g/kg/hr
Despite the valuable information derived from older studies evaluating type 1 diabetes, the diabetes research community has, in large part, overlooked potential contributions of baseline abnormalities in β cell function to T1D development. Newer studies focusing on higher risk individuals often exclude family members without evidence of positive islet autoantibodies. New technologies to assay alternative biomarkers of β cell stress and death remain incompletely explored in both Ab negative and Ab positive family members of T1D patients. Specifically, modern biomarkers of β cell dysfunction have not been rigorously tested in combination with metabolic testing to fully understand their association with insulin secretion. The investigator's working hypothesis is that individuals at genetic risk for T1D exhibit baseline β cell dysfunction, even before development of detectable islet autoimmunity (seropositivity for islet Abs).
The primary objective of this study is to assess hepatic glucose uptake using non-invasive metabolic imaging in three different populations that differ in terms of insulin and glucose kinetics. Between-group comparison will address the following two hypotheses: i) Hepatic glucose uptake will be lower in participants with type 1 diabetes compared with matched controls due to lack of portal insulin and delayed pharmacokinetics of subcutaneous bolus insulin. ii) Hepatic glucose uptake will be higher in participants after bariatric surgery compared with matched health controls due to accelerated glucose absorption and earlier and higher peak portal glucose and insulin concentrations.
Subjects will use the Omnipod Horizon™ System in Manual Mode in an outpatient setting for 14-days. Subjects will be trained to use the Manual Mode feature of the Omnipod Horizon™ System including how to use the bolus calculator using manual entry of blood glucose values or by using the CGM-informed bolus calculator.
The purpose of the study is to evaluate the efficacy in glycemic control and the impact on the quality of life of patients using the MiniMed™ 780G System for the treatment of Type 1 diabetes, in real life settings in France.
The purpose of this research study is to find out if Type 1 Diabetes (T1D) affects skeletal muscle health and if we can improve glycemic control by improving skeletal muscle health. Participants in this study will have a blood sample and a urine sample collected after taking a single dose of a nontoxic chemical called D3-creatine. Their body composition will be measured by a scale like device. Parents of participating children will also be asked to complete a food and activity questionnaire. Participants will be in the study for roughly 12 to 24 months. Enrollment will begin once participant signs the consent form. At the 12 month follow-up visit participants will be asked to wear a Garmin physical activity monitor and use the Garmin Connect mobile app for a period of up to 12 months and take a one time Muscle Strength Measurement test. The greatest risks of this study include the possibility of loss of confidentiality.
In a previous study investigating the effects of intermittent fasting, our research group found evidence for higher glucose excursions and a reduced insulin response after a 36 hour fasting period as compared to an overnight fasting period in healthy subjects. The aim of this research project is to investigate the effect of short and midterm fasting (12 hours versus 36 hours) on glucose metabolism, glucose regulatory hormones, insulin secretion and resting energy expenditure in healthy and obese people as well as in patients with type 2 diabetes.
This study is a case-control study comparing the skin barrier between 50 T1D patients with healthy controls in 3 age-strata including both pediatric and adult patients.
The DreaMed Advisor Pro, is a software which automatically analyses treatment information, learns patient's needs and accordingly suggests adjustments in insulin dosing (FDA approved decision support system). The Advisor Pro uses information gathered from glucose monitoring (sensor readings or capillary blood glucose measurements), insulin dosing and meal data during daily routine home care. Following a 5 minute data collection and analysis, the algorithm learns and suggests pump-setting changes for optimization of glucose control. The algorithm is designed as an advisory tool for health care professionals and has three main components: First, data analysis report - a statistical analysis of the insulin pump and sensor data: insulin delivery, bolus-calculator rate of use, sensor glucose variables, hypoglycemic and hyperglycemic patterns. Second, recommendations, alert messages based on aforementioned data for example "pay attention- you skipped boluses", basal/bolus ratio is too high, bolus delivery compliance, glucose target recommendations and more. Third, a recommendation for new insulin pump settings: including basal intervals and rate, different carbohydrate ratio according to time of day, correction factor and insulin sensitivity time. The Advisor Pro can be used to optimize insulin pump setting during clinical visits, in-between visits or as part of virtual (telemedicine) visit. The objective of the proposed study is to evaluate the use of Advisor Pro by Health Care Providers for regular clinical visits and in between visits titration for adjustment of insulin pump settings. The study design is an open label, prospective, observational study that will include up to 100 participants with Type 1 Diabetes using insulin pumps and monitoring glucose levels by continuous glucose monitoring including flash glucose monitoring.
Randomised controlled trial to contribute to the evidence base for the optimal initial insulin profile for adults with type 1 diabetes commencing insulin pump therapy.
