    • Hsa-miR-376c-3p targets cyclin D1 and induces G1-cell cycle arrest in neuroblastoma cells 

      Bhavsar, Swapnil Parashram; Løkke, Cecilie; Flægstad, Trond; Einvik, Christer (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-11)
      High‑risk neuroblastoma is the most aggressive form of cancer in children. The estimated survival of children with high‑risk neuroblastoma is 40‑50% compared with low and intermediate risk neuroblastoma, which is >98 and 90‑95%, respectively. In addition, patients with high‑risk neuroblastoma often experience relapse following intensive treatments with standard chemotherapeutic drugs. Therefore ...

      Otterdal, Kari; Berg, Åse; Michelsen, Annika; Patel, Sam; Tellevik, Marit Gjerde; Haanshuus, Christel Gill; Fevang, Børre; Aukrust, Pål; Langeland, Nina; Ueland, Thor (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-18)
      <i><p>Background</i>: The immune response during P. falciparum infection is a two-edged sword, involving dysregulation of the inflammatory responses with several types of immune cells participating. Here we examined T-cell, monocyte/macrophage and neutrophil activation during P. falciparum infection by using soluble activation markers for these leukocyte subsets.</p> <i><p>Methods</i>: In a ...
    • Regular physical activity and risk of venous thromboembolism 

      Evensen, Line Holtet; Brækkan, Sigrid Kufaas; Hansen, John-Bjarne (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-05)
      Venous thromboembolism (VTE) is a complex multifactorial disease that represents a growing public health concern. Identification of modifiable risk factors at the population level may provide a measure to reduce the burden of VTE. In this review, we summarize current knowledge of the role of physical activity on the risk of VTE and VTE-related complications. We also discuss methodological challenges ...

      <p><i>Background</i>: Whether physical activity influences the risk of incident venous thromboembolism (VTE) remains controversial, potentially because of methodological challenges, such as regression dilution bias.</p> <p><i>Objectives</i>: To investigate whether physical activity was associated with VTE risk, and explore the role of body mass index (BMI) as a mediator in a population‐based ...
    • The importance of cultural awareness when planning and implementing telepsychiatric services in rural and remote areas 

      Acharibasam, Jeremiah; Wynn, Rolf (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-24)
      <p><i>Introduction</i>: Increasing populations and an increasing incidence of mental health problems challenge many developing countries, including Ghana. Long distances, financial limitations, lack of mental health personnel, and pessimism about the effectiveness of treatment, make it difficult for people to access help. In 2011, only 0.3% of Ghana’s 25 million population received psychiatric ...

    • Women with fracture, unidentified by FRAX, but identified by cortical porosity, have a set of characteristics that contribute to their increased fracture risk beyond high FRAX score and high cortical porosity 

      Kral, Rita; Osima, Marit; Vestgaard, Roald; Richardsen, Elin; Bjørnerem, Åshild (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-25)
      The Fracture Risk Assessment Tool (FRAX) is widely used to identify individuals at increased risk for fracture. However, cortical porosity is associated with risk for fracture independent of FRAX and is reported to improve the net reclassification of fracture cases. We wanted to test the hypothesis that women with fracture who are unidentified by high FRAX score, but identified by high cortical ...
    • Systematic reporting to improve the emergency medical response to major incidents: A pilot study 

      Hardy, Sophie; Fattah, Sabina; Wisborg, Torben; Raatiniemi, Lasse; Staff, Trine; Rehn, Marius (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-24)
      <i>Background:</i> Major incidents affect us globally, and are occurring with increasing frequency. There is still no evidence-based standard regarding the best medical emergency response to major incidents. Currently, reports on major incidents are non-standardised and variable in quality. This pilot study examines the first systematic reports from a consensus-based, freely accessible database, ...

    • 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 ...

    • Associations between complement pathways activity, mannose-binding lectin, and odds of unprovoked venous thromboembolism 

      Høiland, Ina Isabella; Liang, Robin Amanda; Hindberg, Kristian; Latysheva, Nadezhda; Brekke, Ole-Lars; Mollnes, Tom Eirik; Hansen, John-Bjarne (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-30)
      INTRODUCTION: Deep vein thrombosis (DVT) originates in the valvular sinuses of large veins in a local milieu characterized by stasis and severe hypoxia. This may induce complement- and coagulation activation, which potentially increases the risk of venous thromboembolism (VTE). The aim of the present study was to investigate whether the activity of the complement pathways, the level of mannose-binding ...

      Orrem, Hilde Lang; Shetelig, Christian; Ueland, Thor; Limalanathan, Shanmuganathan; Nilsson, Per; Husebye, Trygve Guttorm; Aukrust, Pål; Seljeflot, Ingebjørg; Hoffmann, Pavel; Eritsland, Jan; Mollnes, Tom Eirik; Andersen, Geir Øystein; Yndestad, Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-28)
      <p><i>Background</i>: The inflammatory response following myocardial infarction (MI) is prerequisite for proper healing of infarcted tissue, but can also have detrimental effects on cardiac function. Interleukin (IL)-1α and IL-1β are potent inflammatory mediators and their bioactivity is tightly regulated by IL-1 receptor antagonist (IL-1ra) and soluble (s) IL-1 receptors (R). We aimed to examine ...

      <p><i>Objective</i>: It is unclear if activation of inflammatory pathways regulates proprotein convertase subtilisin-kexin type 9 (PCSK9) levels.</p> <p><i>Approach</i>: We evaluated (1) the temporal course of serum PCSK9 during hospitalisation following acute coronary syndrome and associations with markers of inflammation (leucocyte counts, interleukin (IL)-6, C-reactive protein) and lipid levels ...
    • 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 ...
