Biomarkers for Diabetes Mellitus in advanced Peripheral Arterial Disease. Diagnostic performance and outcome prediction of HbA1c, fasting plasma glucose and the oral glucose tolerance test
Hjellestad, Iren Drange (Doctoral thesis, 2019-05-14)Background: At present, the diagnosis of diabetes mellitus (DM) is based on the result from either of three tests; HbA1c, fasting plasma glucose (FPG) or 2-hour post glucose-load value following an oral glucose tolerance ... -
Distinct T cell subsets in adipose tissue are associated with obesity
Haugstøyl, Martha Eimstad; Cornillet, Martin; Strand, Kristina; Stiglund, Natalie; Sun, Dan; Lawrence-Archer, Laurence; Hjellestad, Iren Drange; Sparrelid, Ernesto; Busch, Christian; Hjelmesæth, Jøran Sture; Hertel, Jens Kristoffer; Ponzetta, Andrea; Mellgren, Gunnar; Fernø, Johan; Björkström, Niklas K. (Journal article; Peer reviewed, 2022)Adipose tissue inflammation is a driving factor for the development of obesity-associated metabolic disturbances, and a role of adipose tissue T cells in initiating the pro-inflammatory signaling is emerging. However, data ... -
HbA1c versus oral glucose tolerance test as a method to diagnose diabetes mellitus in vascular surgery patients
Hjellestad, Iren Drange; Astor, Marianne; Nilsen, Roy Miodini; Søfteland, Eirik; Jonung, Torbjørn (Peer reviewed; Journal article, 2013-05-25)Background: The diagnosis of diabetes mellitus (DM) is based on either fasting plasma glucose levels or an oral glucose tolerance test (OGTT). Recently, an HbA1c value of ≥48 mmol/mol (6.5%) has been included as an additional ... -
Phenotypic diversity of human adipose tissue-resident NK cells in obesity
Haugstøyl, Martha; Cornillet, Martin; Strand, Kristina; Stiglund, Natalie; Sun, Dan; Lawrence-Archer, Laurence; Hjellestad, Iren Drange; Busch, Christian; Mellgren, Gunnar; Björkström, Niklas K.; Fernø, Johan (Journal article; Peer reviewed, 2023-02-22)Natural killer (NK) cells have emerged as key mediators of obesity-related adipose tissue inflammation. However, the phenotype of NK cell subsets residing in human adipose tissue are poorly defined, preventing a detailed ... -
Seven-year trajectories of body weight, quality of life and comorbidities following Roux-en-Y gastric bypass and sleeve gastrectomy
Nielsen, Hans Jørgen; Nedrebø, Bjørn Gunnar; Fosså, Alexander; Andersen, John Roger; Assmus, Jörg; Dagsland, Vigdis Halvorsen; Dankel, Simon N; Gudbrandsen, Oddrun Anita; Fernø, Johan; Hjellestad, Iren Drange; Hjermstad, Marianne Jensen; Kolotkin, Ronette Loganzo; Thorsen, Håvard Luong; Mellgren, Gunnar; Flølo, Tone Nygaard (Journal article; Peer reviewed, 2022)Background/objectives There is limited long-term data comparing the outcomes of sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) for severe obesity, both with respect to body weight, quality of life (QOL) and ... -
Spiral Vein-Graft Technique is a durable therapeutic option for Popliteal Artery Aneurysms

Subtype-specific surface proteins on adipose tissue macrophages and their association to obesity-induced insulin resistance
Strand, Kristina; Stiglund, Natalie; Haugstøyl, Martha Eimstad; Kamyab, Seyedeh Zahra; Langhelle, Victoria Puntervold; Dyer, Laurence; Busch, Christian; Cornillet, Martin; Hjellestad, Iren Drange; Nielsen, Hans Jørgen; Njølstad, Pål Rasmus; Mellgren, Gunnar; Björkström, Niklas K.; Fernø, Johan (Journal article; Peer reviewed, 2022)A chronic low-grade inflammation, originating in the adipose tissue, is considered a driver of obesity-associated insulin resistance. Macrophage composition in white adipose tissue is believed to contribute to the pathogenesis ...
