    • Impact of Chronic Inflammation, Assessed by hs-CRP, on the Association between Red Cell Distribution Width and Arterial Cardiovascular Disease: The Tromsø Study 

      Lappegård, Jostein; Ellingsen, Trygve; Hindberg, Kristian; Mathiesen, Ellisiv B.; Njølstad, Inger; Wilsgaard, Tom; Løchen, Maja-Lisa; Brækkan, Sigrid Kufaas; Hansen, John-Bjarne (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-10)
      Red cell distribution width (RDW), a measure of variability in size of circulating erythrocytes, is associated with arterial cardiovascular disease (CVD), but the underlying mechanism remains unclear. We aimed to investigate the impact of chronic inflammation as measured by high sensitivity CRP (hs-CRP) on this relationship, and explore whether RDW could be a mediator in the causal pathway between ...

      Jamaly, Simin; Ramberg, Cathrine; Olsen, Randi; Latysheva, Nadezhda; Webster, Paul; Sovershaev, Timofey; Brækkan, Sigrid Kufaas; Hansen, John-Bjarne (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-21)
      Optimal pre-analytical handling is essential for valid measurements of plasma concentration and size distribution of extracellular vesicles (EVs). We investigated the impact of plasma preparation, various anticoagulants (Citrate, EDTA, CTAD, Heparin), and fasting status on concentration and size distribution of EVs measured by Nanoparticle Tracking Analysis (NTA). Blood was drawn from 10 healthy ...

      The risk of venous thromboembolism (VTE) in patients who survive the first years after a cancer diagnosis after the acute effects of disease and treatment in comparison to a similar background population has been sparsely investigated. The aim of the study was to investigate if incidence rates (IRs) of VTE differed in patients who were alive at least 2 years after a cancer diagnosis without VTE ...
