      Wiedmann, Markus; Skattør, Thor Håkon; Stray-Pedersen, Arne; Romundstad, Luis Georg; Antal, Ellen-Ann; Marthinsen, Pål Bache; Sørvoll, Ingvild Hausberg; Ernstsen, Siw Leiknes; Lund, Christian G.; Holme, Pål Andre; Johansen, Tonje Okkenhaug; Brunborg, Cathrine; Aamodt, Anne Hege; Schultz, Nina Haagenrud; Skagen, Karolina Ryeng; Skjelland, Mona Elisabeth (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-30)
      During a 2-week period, we have encountered five cases presenting with the combination of cerebral venous thrombosis (CVT), intracerebral hemorrhage and thrombocytopenia. A clinical hallmark was the rapid and severe progression of disease in spite of maximum treatment efforts, resulting in fatal outcome in for 4 out of 5 patients. All cases had received ChAdOx1 nCov-19 vaccine 1–2 weeks earlier and ...
    • A rapid, sensitive, and specific assay to measure TF activity based on chromogenic determination of thrombin generation 

      Østerud, Bjarne; Latysheva, Nadezhda; Schoergenhofer, Christian; Jilma, Bernd; Hansen, John-Bjarne; Snir, Omri (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-25)
      Background - Most tissue factor (TF) activity assays are based on measurement of factor X (FX) activation by TF in the presence of factor VII (FVII)/FVIIa. This requires long incubation, which may result in TF-independent activity of FX and inaccurate measurement of TF activity.<p> <p>Aim - To develop a sensitive and specific TF activity assay, which does not register a non-specific TF activity, ...
    • Rosuvastatin treatment decreases plasma procoagulant phospholipid activity after a VTE: A randomized controlled trial 

      Ramberg, Cathrine; Hindberg, Kristian; Biedermann, Joseph S.; Cannegieter, Suzanne C.; van der Meer, Felix J.; Snir, Omri; Leebeek, Frank W. G.; Kruip, Marieke J. H. A.; Hansen, John Bjarne; Lijfering, Willem M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-25)
      Background - Venous thromboembolism (VTE) is a frequent cardiovascular disease with severe complications, including recurrence and death. There is a great need for alternative prophylactic treatment options as anticoagulation is accompanied by increased bleeding risk. Statins are reported to reduce the risk of incident and recurrent VTE, but the mechanisms are elusive. Procoagulant phospholipids ...

      Pedersen, Marit Løtveit; Jozefiak, Thomas; Sund, Anne Mari; Holen, Solveig; Neumer, Simon-Peter; Martinsen, Kristin D.; Rasmussen, Lene Mari P.; Patras, Joshua; Lydersen, Stian (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-27)
      Background - Prevention is essential to reduce the development of symptomology among children and adolescents into disorders, thereby improving public health and reducing costs. Therefore, easily administered screening and early assessment methods with good reliability and validity are necessary to effectively identify children’s functioning and how these develop. The Brief Problem Monitor (BPM) is ...
    • Tocilizumab increases citrullinated histone 3 in non-ST segment elevation myocardial infarction 

      Helseth, Ragnhild; Kleveland, Ola; Ueland, Thor; Wiseth, Rune; Damås, Jan Kristian; Broch, Kaspar; Michelsen, Annika Elisabet; Bendz, Bjørn; Gullestad, Lars; Aukrust, Pål; Seljeflot, Ingebjørg (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-10)
      Objective: Beyond reducing inflammation and troponin T (TnT) release, the interleukin-6 receptor antagonist tocilizumab reduces neutrophil counts in patients with non-ST segment elevation myocardial infarction (NSTEMI). It is unclear if this is related to formation of neutrophil extracellular traps (NETs), carrying inflammatory and thrombotic properties.<p> <p>Methods - In a placebo-controlled ...
    • Trends in Disability-Free Life Expectancy (DFLE) from 1995 to 2017 in the older Norwegian population by sex and education: The HUNT Study 

      Storeng, Siri Høivik; Øverland, Simon Nygaard; Skirbekk, Vegard; Hopstock, Laila Arnesdatter; Sund, Erik Reidar; Krokstad, Steinar; Strand, Bjørn Heine (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-28)
      Aim: Understanding whether increasing Life Expectancy (LE) translates to improved health and function among older adults is essential, but results are inconclusive. We aimed to estimate trends in Disability-Free Life Expectancy (DFLE) in the older Norwegian population by sex and education from 1995 to 2017.<p> <p>Method: National life table data were combined with cross-sectional data on functional ...
    • A porcine model of hemodialyzer reactions: roles of complement activation and rinsing back of extracorporeal blood 

      Pethő, Ákos; Piecha, Dorothea; Mészáros, Tamás; Urbanics, Rudolf; Moore, Christoph; Canaud, Bernard; Mollnes, Tom Eirik; Steppan, Sonja; Szénási, Gábor; Szebeni, János; Dézsi, László (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-09)
      Hemodialysis reactions (HDRs) resemble complement-activation-related pseudoallergy (CARPA) to certain i.v. drugs, for which pigs provide a sensitive model. On this basis, to better understand the mechanism of human HDRs, we subjected pigs to hemodialysis using polysulfone (FX CorDiax 40, Fresenius) or cellulose triacetate (SureFlux-15UX, Nipro) dialyzers, or Dialysis exchange-set without membranes, ...
    • Inspiratory crackles-early and late-revisited: identifying COPD by crackle characteristics 

      Melbye, Hasse; Aviles Solis, Juan Carlos; Jacome, Cristina; Pasterkamp, Hans (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-05)
      Background The significance of pulmonary crackles, by their timing during inspiration, was described by Nath and Capel in 1974, with early crackles associated with bronchial obstruction and late crackles with restrictive defects. Crackles are also described as ‘fine’ or ‘coarse’. We aimed to evaluate the usefulness of crackle characteristics in the diagnosis of chronic obstructive pulmonary disease ...
    • Salmon louse infestation levels on sea trout can be predicted from a hydrodynamic lice dispersal model 

      Bøhn, Thomas; Nilsen, Rune; Gjelland, Karl Øystein; Biuw, Martin; Primicerio, Raul; Karlsen, Ørjan; Serra Llinares, Rosa Maria (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-13)
      1. The abundance of the parasitic salmon louse has increased with the growth in aquaculture of salmonids in open net pens. This represents a threat to wild salmonid populations as well as a key limiting factor for salmon farming. The Norwegian ‘traffic light’ management system for salmon farming aims to increase aquaculture production while securing sustainable wild salmonid populations. However, ...
