Filter by:The purpose of this project is to evaluate the efficacy of a behavioral economic intervention to improve self monitoring of blood glucose (SMBG) in adolescents and young adults with T1D. The intervention will reinforce patients for conducting SMBG, with escalating reinforcers provided when patients achieved sustained periods of testing at least 4 times/day at appropriate intervals. A 6-month trial will be conducted in which 60 patients will be randomized to: (1) standard care or (2) standard care plus the reinforcement intervention.
The potential of currently available diabetes technologies could be further exploited. The investigators propose that sensor-augmented insulin pump therapy may be improved by continuous correction, i.e. continuous evaluation of the need for correction boluses. In practice, this is carried out by running the bolus calculator every 10 minutes. The glucose sensor will provide the bolus calculator with glucose input. Many times, the bolus calculator will come to the result that no insulin is needed. However, when the blood glucose is above the pre-set target value and a correction bolus is needed, an appropriate bolus is automatically delivered by the insulin pump. The investigators hypothesize that sensor-augmented continuous correction insulin pump therapy can reduce hyperglycemia without increasing the risk of hypoglycemia in patients with type 1 diabetes.
The aim of the study is to assess the efficacy and safety of a closed-loop system consisting of a predictive rule-based algorithm integrated on the Medtronic Portable Glucose Control System (PGCS) in patients with type 1 diabetes for controlling the nocturnal and post-breakfast periods. Intervention will be to apply the automated closed-loop system by administering a subcutaneous insulin microbolus every 5 minutes depending on reading from a continuous glucose measurement (CGM) system.
Investigators hope that providing patients and families with additional ways of communication with the diabetes care team will improve diabetes control.
During pregnancy nutrition demands change and the pregnant woman needs to adjust her food intake and take into consideration the corrected daily recommendations for micro and macro nutrients. Pregnant woman tend to suffer from hyperemesis and this affects their food choice. Amongst pregnant women with Diabetes the glucose balance is extremely important during pregnancy. Glucose balance is a result of correct nutrition and an exact amount of insulin. This delicate balance requires from the pregnant women an ability to perform correct carbohydrate count. Hyperglycemia has already been proven to affect the fetus and the neonatal outcomes. Hypoglycemia may also have a negative effect but the main danger is immediate harm to the mother and therefore to the fetus. For those reasons glucose balance is crucial and demands delicate synchronization of nutrition and insulin therapy.
This is an observational study of children and young adults ages 6-20 years with type 1 diabetes and age- and race-matched controls. The investigators will be examining blood and urine hormone levels as well as measures of bone density including DXA and high-resolution peripheral quantitiative computed tomography. The investigators will also be collecting data regarding physical activity via use of wearable accelerometers. The investigators hypothesize that youth with type 1 diabetes will have slower bone accrual and impaired bone microarchitectural integrity compared with non-diabetic controls, and that bones of individuals with type 1 diabetes will not respond as well to physical activity. The investigators hypothesize that poor bone accrual will be associated with sub-optimal glucose control as well as lower levels of insulin-like growth factor 1.
The Continuous Subcutaneous Insulin Infusion (CSII) might have an impact on psychological distress and some psychological factors might be predictors of metabolic control; however, very few studies conducted so far were specifically focused on the psychological aspects of CSII therapy in adults affected by T1DM.
The purpose of this study is to see if an automated insulin management system ("study system") can safely be used at home to manage blood sugar. The study system includes (1) a CGM that measures glucose levels, (2) a computer program on a smartphone that determines how much insulin is needed and allows the study participant user to control the whole system, and (3) an insulin pump that delivers the insulin. The CGM will be from Dexcom. The pump will be from Roche. The CGM and pump are similar to the devices that are currently available for people to purchase and use. However, the smartphone device, the CGM sensor type used with it, and the overall study system can only be used for research at this time. The study will be completed by about 24 individuals at 6 centers in the United States and Europe. This study has several phases and will take about 11-14 weeks to complete depending on whether the study participant is a CGM user or not. At selected sites (based on subject eligibility and availability), approximately 10-20 subjects who exhibit safe and competent use of the system at home will be given the option to continue home use of the system in Day-and-Night Closed-Loop mode for up to 5 months.
This study is designed to look at how snacking during exercise may help prevent low blood sugars while subjects are on the "closed loop artificial pancreas." This system uses a continuous glucose sensor, an insulin pump, and a computer program that automatically determines how much insulin to give based on the sensor glucose level.
Nutritional therapy has a major role in diabetes care, achieving and maintaining metabolic control: normal glucose homeostasis, normal lipid profile, normal blood pressure and desirable weight. Controlled nutritional diet, as introduced by the professional committees aims at achieving better general health condition. There is a growing body of evidence showing that Mediterranean diet has a major role in prevention of diabetes sequelae in type 2 diabetes patients. Hitherto, the effects of Mediterranean diet on patients with type 1 diabetes has not been studied, with the exception of one Italian study. Six months after education to consume Mediterranean diet in a cohort of 96 children with type 1 diabetes the authors observed decreased fat and cholesterol consumption, increased dietary fiber consumption, lower LDL cholesterol levels and better HDL to LDL cholesterol ratio. The proposed study is aimed to assess the impact of Mediterranean nutrition compared to the accepted nutritional guidelines, in newly diagnosed type 1 children and adolescents on lipid profile, metabolic control, C peptide, daily insulin dose, Inflammatory parameters, endothelial function and anthropometric parameters 12 months following diagnosis. The study designed as a two parallel arms, randomized, single center, intervention study. Patients enrolled to the study will be randomly assigned, to one of the following groups in a 1:1 ratio. Interventional Arm: Patients assigned to the interventional arm will receive nutritional instructions of Mediterranean diet and Control Group: Patients assigned to the interventional arm will receive regular nutritional instructions in accordance with the accepted nutritional guidelines
