The Artificial Pancreas: Two Alternative Approaches to Achieve a Fully Closed Loop System with Optimal Glucose Control
Åm, Marte Kierulf; Teigen, Ingrid Anna; Riaz, Misbah; Fougner, Anders Lyngvi; Christiansen, Sverre Christian; Carlsen, Sven Magnus (Peer reviewed; Journal article, 2023)Introduction Diabetes mellitus type 1 is a chronic disease that implies mandatory external insulin delivery. The patients must monitor their blood glucose levels and administer appropriate insulin boluses to keep their ... -
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 ... -
Identifiable Prediction Animal Model for the Bi-Hormonal Intraperitoneal Artificial Pancreas
Davari Benam, Karim; Khoshamadi, Hasti; Åm, Marte Kierulf; Stavdahl, Øyvind; Gros, Sebastien; Fougner, Anders Lyngvi (Peer reviewed; Journal article, 2022)To achieve a fully automatic artificial pancreas (AP), i.e., an AP without the need for meal announcements, the intraperitoneal (IP) route is explored. This route has faster dynamics than the typical subcutaneous (SC) ... -
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 ... -
Intraperitoneal insulin administration in pigs: Effect on circulating insulin and glucose levels
Dirnena-Fusini, Ilze; Åm, Marte Kierulf; Fougner, Anders Lyngvi; Carlsen, Sven Magnus; Christiansen, Sverre Christian (Peer reviewed; Journal article, 2021)Introduction The effect of intraperitoneal insulin infusion has limited evidence in the literature. Therefore, the aim of the study was to investigate the pharmacokinetics and pharmacodynamics of different intraperitoneal ... -
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 ... -
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 ...
