Artificial Pancreas With Different Stress Assessments in the Outpatient Setting

2019-10-31 14:29:32 | BioPortfolio


This feasibility study is a randomized crossover trial that will compare the efficacy and safety of an automated insulin delivery (AID) system in patients with type 1 diabetes using a Model Predictive Control (MPC) algorithm versus sensor augmented pump therapy (SAP)/Predictive Low Glucose Suspend (PLGS), and will include different stress induction and assessments over a 4 week period.


Eligible participants will be randomly assigned to one of two treatment arms: 1) AID for two weeks and SAP/PLGS for two weeks , or 2) SAP/PLGS for two weeks and AID for two weeks. During the 4-week trial, subjects will wear the Empatica E4 wristband every day to record electrodermal activity, accelerometer and heartrate data. Subjects will also complete logbooks to record activity and stress. During each two-week period, subjects will come to the clinical center twice for stress induction tests in a medically supervised setting.

Hybrid Closed-Loop Control Is Safe and Effective for People with Type 1 Diabetes Who Are at Moderate to High Risk for Hypoglycemia.

Typically, closed-loop control (CLC) studies excluded patients with significant hypoglycemia. We evaluated the effectiveness of hybrid CLC (HCLC) versus sensor-augmented pump (SAP) in reducing hypogly...

Cost-effectiveness of sensor-augmented insulin pump therapy versus continuous subcutaneous insulin infusion in patients with type 1 diabetes in Turkey.

Background and Aims Sensor-augmented pump therapy (SAP) combines continuous glucose monitoring (CGM) with continuous subcutaneous insulin infusion (CSII). SAP is costlier than CSII but provides additi...

Medical and Biotech [MESH] Definitions

The time period before the development of symptomatic diabetes. For example, certain risk factors can be observed in subjects who subsequently develop INSULIN RESISTANCE as in type 2 diabetes (DIABETES MELLITUS, TYPE 2).

A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.

Devices for simulating the activity of the pancreas. They can be either electromechanical, consisting of a glucose sensor, computer, and insulin pump or bioartificial, consisting of isolated islets of Langerhans in an artificial membrane.

A severe type of hyperlipidemia, sometimes familial, that it is characterized by the elevation of both plasma CHYLOMICRONS and TRIGLYCERIDES contained in VERY-LOW-DENSITY LIPOPROTEINS. Type V hyperlipoproteinemia is often associated with DIABETES MELLITUS and is not caused by reduced LIPOPROTEIN LIPASE activity as in HYPERLIPOPROTEINEMIA TYPE I .

Urination of a large volume of urine with an increase in urinary frequency, commonly seen in diabetes (DIABETES MELLITUS; DIABETES INSIPIDUS).
