Filter by:People with type 1 diabetes often find exercise very difficult to manage, because of the high risk for low blood glucose levels. This can occur very quickly once exercise starts and presents many risks for subjects, such as severe symptoms, confusion, passing out, seizures, and even coma or death in very severe cases. Preventing low blood glucose levels during and after exercise is important because physical exercise is a key component of managing diabetes. It is often hard to correctly adjust insulin infusion rates or doses before exercise as the relationship between exercise and changes in glucose levels in those who have type 1 diabetes is still not fully understood. Therefore, the investigators propose this study to further our understanding in this area. This study is designed to help separate the effects of insulin from those of muscle work (non-insulin effects) on the changes in blood glucose levels during aerobic exercise. The main hypothesis is that the non-insulin effects occur quickly during exercise and account for the rapid change in blood glucose levels once aerobic exercise begins. These effects can be separated from the slower changes in insulin sensitivity that occur because of exercise, and which account for reduced insulin demand even after exercise has stopped. The investigators will investigate the effects of both moderate and intense aerobic exercise at different levels of insulin in the body to help separate the insulin and non-insulin effects. The investigators wish to recruit 26 subjects to take part in this study. Subjects will be randomly divided into two groups, with 13 in each group. Group 1 will undergo moderate aerobic exercise, while group 2 will undergo intense aerobic exercise. Each subject will repeat the exercise study three times on three separate days at least 2 weeks apart, while having insulin infused at a low, a medium, and a high rate. Subjects will have an IV line placed in each arm, one for drawing blood relatively frequently during the study, and another for infusion of insulin, glucose, and a special glucose tracer (non-radioactive). Each study lasts about 9 hours. Information from this study will be used to help develop a mathematical model of how glucose changes during exercise in type 1 diabetes. Such a model of type 1 diabetes and exercise will be very useful for adjusting insulin doses in patients who use multiple daily injections of insulin, and can help to guide an automated insulin delivery system, such as the artificial pancreas.
This is a study to assess the effectiveness of CGM (Continuous Glucose Monitor), enhanced by a diabetes management platform (DMP), collectively called enhanced CGM (eCGM), in the care of older patients with T1D. The DMP includes an automated data transfer from CGM, insulin-delivery devices, and activity tracker to a clinical decision support system (CDS) that provides dosing adjustment recommendations based on that data to the healthcare team. In addition, the DMP includes on-demand education for patients and caregivers, and an interface for communication between providers, patients, and their caregivers.
Annually in the U.S 300,000 neonates are born late preterm, defined as 34 weeks 0 days - 36 weeks 6 days. The Antenatal Late Preterm Steroids (ALPS) Trial demonstrated that maternal treatment with betamethasone in the late preterm period significantly reduces neonatal respiratory complications, but also increases neonatal hypoglycemia, compared to placebo. This research study will attempt to answer the following primary question: Does a management protocol aimed at maintaining maternal euglycemia after ALPS decrease fetal hyperinsulinemia, compared to usual antepartum care?
The overall objective and Primary Aim of this Limited Competition: Small Grant Program (R03) is to address the critical need of identifying and decreasing fear of hypoglycemia, which will be accomplished by conducting a pilot randomized clinical trial to evaluate the efficacy of Blood Glucose Awareness Training, which has been adapted for, but never evaluated in adolescents with Type 1 Diabetes (T1D) and their parents.
The purpose of the study is to determine the effects of insulin suspension at start of exercise in individuals with type 1 diabetes. A total of 3 sessions will be required for this project. The first will be a familiarization session that requires completed informed consent, anthropometric measurements (height, weight, body fat percentage), questionnaires, and a test of maximal aerobic fitness. The remaining 2 sessions will be steady-state aerobic exercise as well as circuit exercise.
This study compares the hypoglycemic counter regulatory response in type 1 diabetics and in healthy control subjects with and without antecedent hypoglycemia
Hypoglycemia is the most common metabolic problem faced after birth. The investigators will be studying the utility of using a continuous glucose monitoring(CGM) system to more closely monitor low blood sugars in newborns. The investigators will evaluate the number of hypoglycemic events detected using CGM and compare it to those detected using current standard of care screening methods.
This clinical study proposes to assess the impact of Libre on frequency, duration and severity of hypoglycaemia, compared with the Dexcom G5 realtime CGM and will focus on people with impaired awareness of hypoglycaemia.
The EarEEG system is a novel non-invasive, unobstructed and discrete method for recording EEG in which the signal is recorded using dry-contact electrodes embedded on a customised ear piece. One intended medical indication of the EarEEG system is the detection of hypoglycaemia-induced changes in the EEG in patients with type 1 diabetes. Currently, no studies exist investigating the detection of hypoglycaemic episodes by use of ear electrodes. While a finger prick test accurately measures the blood glucose level, it does not provide continuous measurements, and hence it is unreliable as a hypoglycaemia alarm. Recent studies have indicated that the use of continuous glucose monitoring (CGM) reduces the risk of severe hypoglycaemia. However, some find these devices troublesome to use and utilisation of CGM has remained limited to date. Observational data show that only a small percentage of patients with type 1 diabetes are using CGM on an ongoing basis. Thus, there is a medical need for a reliable hypoglycaemia detection device which is easy and convenient to use. This clinical study aims at investigating the feasibility of measuring hypoglycaemia induced changes in the EEG by use of the EarEEG system.
Hypoglycaemia in subjects suffering from type 2 diabetes may have substantial consequences including a significant negative impact on quality of life. Further, repeated minor hypoglycaemias may result in significant productivity losses. Here, the investigators propose to provide quantitative results on cognition during an acute mild hypoglycaemic episode (target plasma glucose 3 mmol/L) in 28 subjects with type 2 diabetes. Data will be provided on executive function, attention and memory.
