New technologies in the treatment of type 1 diabetes

Type 1 diabetes is a chronic condition characterized by insufficient production of insulin, a hormone needed for proper control of blood glucose levels. People with type 1 diabetes must monitor their blood glucose throughout the day using a glucose meter or a continuous glucose monitor, calculate how much insulin is needed to maintain normal blood glucose levels, and administer the insulin dose by pen injection or insulin pump infusion into the subcutaneous tissue. In recent years, several new technologies for the treatment of type 1 diabetes have been developed. This PhD thesis covers two studies of the effects of commercially available technologies--sensor-augmented pump therapy and automated insulin bolus calculators--when used in clinical practice. Both studies demonstrated that these technologies have the potential to improve diabetes care. In addition, two in-clinic studies related to emerging technologies--closed-loop glucose control and virtual simulation environments--are included in the thesis. The results of these experiments provided proof of concept and will serve as a basis for further research in these fields.
