Filter by:This project will study whether infants with Prader-Willi Syndrome experience low blood sugars after short periods of fasting. This study will also evaluate metabolic markers in the blood to determine if infants with Prader-Willi Syndrome process energy differently than other children during fasting.
With increasing rates of obesity the number of anti-obesity operations performed is increasing; one of the most common is gastric bypass. Anti-obesity surgery ameliorates diabetes and several other serious comorbidities, but bariatric surgery is also associated with medical and nutritional complications. Post-gastric bypass hyperinsulinemic hypoglycemia is a relative rare but serious complication often seen months to years after gastric bypass surgery. The patients experience neuroglycopenic symptoms (eg. inability to concentrate, weakness, altered mental status, loss of consciousness). The purpose of this study is to determine whether glucagon-like peptide-1 (GLP-1)or other enteropancreatic factors (eg. gastric emptying rate) are responsible for the excessed insulin secretion seen in some patients after bariatric surgery.
Low blood sugar can negatively affect how blood vessels function, and this can lead to an increase in the risk for heart attacks, strokes and other problems related to the stiffening and blockage of blood vessels. The purpose of this study is to learn if and how glucagon-like peptide-1 (GLP-1; a naturally occurring hormone in the gut) changes the effects that low blood sugar levels have on blood vessels.
The hippocampus is an area of brain which plays an essential role in learning and memory processing and is thought to be particularly vulnerable to effects of hypoglycemia (low blood glucose). The goal of this project is to examine hippocampal neurochemistry and metabolism and identify how diabetes and recurrent hypoglycemia alter the hippocampus.
The purpose of this study is to determine whether pramlintide (Symlin) will help to reduce the frequency and severity of hypoglycemia in individuals who have had gastric bypass surgery.
The purpose of this study is to determine if patients have more hypoglycemic episodes the first 3 days following pump start compared to their usual number of hypoglycemias with our actual pump initiation protocol.
In the unfortunate case of severe hypoglycaemia, glucagon is the first-line treatment because of its potent and rapid action starting as fast as 5 minutes after subcutaneous or intramuscular injection. Large dose of glucagon such as 1 mg subcutaneous is usually associated with undesirable side-effects such as nausea, vomiting, bloating and headache. The overall objective of this research proposal is to assess the efficacy of lower subcutaneous doses of glucagon (0.1 mg or 0.2 mg) to correct hypoglycaemia compared to the standard dose (1.0 mg) in adults with type 1 diabetes mellitus (T1D). It is postulated that much lower dosages of glucagon (0.1 or 0.2 mg) injected subcutaneously will be just as effective as the current recommended dose of 1.0 mg to correct hypoglycaemia without the undesirable gastro-intestinal side effects.
The purpose of this study is to see whether low blood sugar at night can be reduced by using a system that turns off the insulin pump automatically. The study system includes a continuous glucose monitor (CGM) and an insulin pump. The CGM and pump work with a regular laptop computer. A The system works by (1) measuring the glucose levels under the skin with the CGM, (2) using a computer program on the laptop to predict whether a low blood sugar is likely to occur, and (3) turning off the insulin pump when the computer program predicts that a low blood sugar will occur. We have tested the system in the home environment in individuals with type 1 diabetes age 15 years and older. We have found an indication that the system can decrease the frequency of hypoglycemia. We have not had any serious cases of high blood sugars or other problems. We are now ready to further test the system in the home environment in a younger age group to learn more about its ability to reduce overnight low blood sugar risk. This study has several phases and will take about 3 months for a patient to complete. - First, the patient will use the CGM and pump at home for up to 15 days with the help of a parent/guardian. This is done to determine if the patient meets our study criteria to proceed with the next phase of the study. - If the patient is eligible to continue in the study, the patient will need to use the full study system for at least 5 nights at home with the help of a parent/guardian. This is done to make sure the patient and parent/guardian are able to use the system correctly. The patient may participate in starting and stopping the system at home, but the parent/guardian is responsible for making sure it is used as instructed. - After that, the patient will be asked to use the study system each night for an additional 6 to 8 weeks. The parent/guardian will remain responsible for making sure the system is used as instructed. The study will include about 90 individuals with type 1 diabetes at 3 clinical centers in the United States and Canada. First a study of children 8 to less than 15 years old will be done. Then, a study of children 3 to less than 8 years old will be conducted.
The goals of this proposal are to determine the effects of hypoglycemia on the autonomic nervous system.
This trial is conducted in Europe. The aim of the trial is to compare cognitive function and associated brain activation patterns during an acute hypoglycaemic episode and during euglycaemia (normal blood glucose concentration). Additionally, the purpose is to assess cognitive function in the recovery phase after hypoglycaemia or euglycaemia, respectively, in subjects with type 1 diabetes.
