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 ... -
The effect of glucagon on local subcutaneous blood flow in non-diabetic volunteers; a proof-of-concept study
Åm, Marte Kierulf; Munkerud, Erlend Yttersian; Berge, Mathilde Hallem; Christiansen, Sverre Christian; Carlsen, Sven Magnus (Peer reviewed; Journal article, 2022)Introduction Glucagon and insulin are the two most important hormones for glucose metabolism and have been incorporated in the dual-hormonal artificial pancreas, a device for automated glucose regulation for people with ... -
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 ... -
Pharmacokinetics of Intraperitoneally Delivered Glucagon in Pigs: A Hypothesis of First Pass Metabolism
Teigen, Ingrid Anna; Åm, Marte Kierulf; Carlsen, Sven Magnus; Christiansen, Sverre Christian (Peer reviewed; Journal article, 2021)Background and Objective Artificial pancreases administering low-dose glucagon in addition to insulin have the scope to improve glucose control in patients with diabetes mellitus type 1. If such a device were to deliver ... -
Physiological effects of intraperitoneal versus subcutaneous insulin infusion in patients with diabetes mellitus type 1: A systematic review and meta-analysis
Dirnena-Fusini, Ilze; Åm, Marte Kierulf; Fougner, Anders Lyngvi; Carlsen, Sven Magnus; Christiansen, Sverre Christian (Peer reviewed; Journal article, 2021)The intraperitoneal route of administration accounts for less than 1% of insulin treatment regimes in patients with diabetes mellitus type 1 (DM1). Despite being used for decades, a systematic review of various physiological ... -
Severe bradycardia and hypotension in anaesthetized pigs: Possible interaction between octreotide, xylazine, and atropine: A case series
Åm, Marte Kierulf; Teigen, Ingrid Anna; Carlsen, Sven Magnus; Christiansen, Sverre Christian (Peer reviewed; Journal article, 2023)Pigs are common animal models in diabetes research. Streptozotocin-induced destruction of pancreatic β-cells is used to induce diabetes in conscious pigs. However, in short-term non-recovery experiments, suppression of ... -
Vasodilatory effects of glucagon: A possible new approach to enhanced subcutaneous insulin absorption in artificial pancreas devices
Teigen, Ingrid Anna; Riaz, Misbah; Åm, Marte Kierulf; Christiansen, Sverre Christian; Carlsen, Sven Magnus (Peer reviewed; Journal article, 2022)Patients with diabetes mellitus type 1 depend on exogenous insulin to keep their blood glucose concentrations within the desired range. Subcutaneous bihormonal artificial pancreas devices that can measure glucose concentrations ...
