      Hestad, Knut A.; Engedal, Knut; Whist, Jon Elling; Aukrust, Pål; Farup, Per Grønaas; Mollnes, Tom Eirik; Ueland, Thor (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-04-13)
      INTRODUCTION: Several reports indicate that inflammation may play a role in depression and demonstrate enhanced systemic levels of inflammatory mediators. We hypothesized that 44 patients with a diagnosis of depression would present with a specific and different serum and cerebrospinal fluid (CSF) cytokine profile compared to 21 patients with diffuse neurological symptoms, of whom 15 had fatigue as ...
    • Plasma hepcidin is associated with future risk of venous thromboembolism 

      Ellingsen, Trygve; Lappegård, Jostein; Ueland, Thor; Aukrust, Pål; Brækkan, Sigrid Kufaas; Hansen, John-Bjarne (Journal article; Tidsskriftartikkel; Peer reviewed, 2018)
      Red cell distribution width (RDW) is associated with venous thromboembolism (VTE), but the underlying mechanism(s) is unclear. Iron deficiency is associated with high RDW, and studies suggest an association between iron deficiency and VTE. To assess whether iron deficiency is a risk factor for VTE that explains the association between RDW and VTE, we conducted a nested case-control study of 390 ...
