A Review of the Current Challenges Associated with the Development of an Artificial Pancreas by a Double Subcutaneous Approach
Christiansen, Sverre; Fougner, Anders Lyngvi; Stavdahl, Øyvind; Kölle, Konstanze; Ellingsen, Reinold; Carlsen, Sven Magnus (Journal article; Peer reviewed, 2017)Introduction Patients with diabetes type 1 (DM1) struggle daily to achieve good glucose control. The last decade has seen a rush of research groups working towards an artificial pancreas (AP) through the application of a ... -
Differences Between Flash Glucose Monitor and Fingerprick Measurements
Staal, Odd Martin; Hansen, Heidi Marie Umbach; Christiansen, Sverre; Fougner, Anders Lyngvi; Carlsen, Sven Magnus; Stavdahl, Øyvind (Journal article; Peer reviewed, 2018)Freestyle Libre (FL) is a factory calibrated Flash Glucose Monitor (FGM). We investigated Mean Absolute Relative Difference (MARD) between Self Monitoring of Blood Glucose (SMBG) and FL measurements in the first day of ... -
Effect of sensor location on continuous intraperitoneal glucose sensing in an animal model
Åm, Marte Kierulf; Kölle, Konstanze; Fougner, Anders Lyngvi; Dirnena-Fusini, Ilze; Bösch, Patrick Christian; Ellingsen, Reinold; Hjelme, Dag Roar; Stavdahl, Øyvind; Carlsen, Sven Magnus; Christiansen, Sverre (Journal article; Peer reviewed, 2018)In diabetes research, the development of the artificial pancreas has been a major topic since continuous glucose monitoring became available in the early 2000’s. A prerequisite for an artificial pancreas is fast and reliable ... -
Enhancement of Insulin Absorption by Local Manipulation of the Site of Injection
Finne, Solveig Nyland (Master thesis, 2019)Bakgrunn: Trege og uforutsigbare absorpsjonsprofiler av subkutant injiserte måltidsinsuliner er ansett som en stor utfordring i behandlingen av diabetes type 1, og resulterer ofte i en forsinket topp og en langvarig ... -
Intraperitoneal and subcutaneous glucagon delivery in anaesthetized pigs: effects on circulating glucagon and glucose levels
Åm, Marte Kierulf; Dirnena-Fusini, Ilze; Fougner, Anders Lyngvi; Carlsen, Sven Magnus; Christiansen, Sverre (Journal article; Peer reviewed, 2020)Glucagon is a pancreatic hormone and increases the blood glucose levels. It may be incorporated in a dual hormone artificial pancreas, a device to automatically and continuously control blood glucose levels of individuals ... -
The intraperitoneal artificial pancreas: glucose sensing and glucagon delivery
Åm, Marte Kierulf (Doctoral theses at NTNU;2020:267, Doctoral thesis, 2020)Norsk sammendrag Diabetes er en gruppe sykdommer som globalt rammer millioner av mennesker. Denne avhandlingen fokuserer på diabetes mellitus type 1 som kjennetegnes av ingen, eller veldig liten, produksjon av insulin. ... -
Intraperitoneal, subcutaneous and intravenous glucagon delivery and subsequent glucose response in rats: A randomized controlled crossover trial
Dirnena-Fusini, Ilze; Åm, Marte Kierulf; Fougner, Anders Lyngvi; Carlsen, Sven Magnus; Christiansen, Sverre (Journal article; Peer reviewed, 2018)Objective Hypoglycemia is a frequent and potentially dangerous event among patients with diabetes mellitus type 1. Subcutaneous glucagon is an emergency treatment to counteract severe hypoglycemia. The effect of intraperitoneal ... -
Pattern recognition reveals characteristic postprandial glucose changes: Non-individualized meal detection in diabetes mellitus type 1
Kölle, Konstanze; Biester, Torben; Christiansen, Sverre; Fougner, Anders Lyngvi; Stavdahl, Øyvind (Journal article; Peer reviewed, 2019)Accurate continuous glucose monitoring (CGM) is essential for fully automated glucose control in diabetes mellitus type 1. State-of-the-art glucose control systems automatically regulate the basal insulin infusion. Users ... -
Why intraperitoneal glucose sensing is sometimes surprisingly rapid and sometimes slow: A hypothesis
Åm, Marte Kierulf; Fougner, Anders Lyngvi; Ellingsen, Reinold; Hjelme, Dag Roar; Bösch, Patrick Christian; Stavdahl, Øyvind; Carlsen, Sven Magnus; Christiansen, Sverre (Journal article; Peer reviewed, 2019)The artificial pancreas requires fast and reliable glucose measurements. The peritoneal space has shown promising results, and in one of our studies we detected glucose changes in the peritoneal space already at the same ...
