      Fenton, Christopher Graham; Taman, Hagar; Florholmen, Jon; Sørbye, Sveinung; Paulssen, Ruth H (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-23)
      <i>Background</i> - This study addresses whether existing specific transcriptional profiles can improve and support the current status of the definition of ulcerative colitis (UC) remission apart from the existing endoscopic, histologic, and laboratory scoring systems. For that purpose, a well-stratified UC patient population in remission was compared to active UC and control patients and was ...

      <i>Background</i> - Imaging for osteoporosis has two major aims, first, to identify the presence of low bone mass (osteopenia), and second, to quantify bone mass using semiquantitative (conventional radiography) or quantitative (densitometry) methods. In young children, densitometry is hampered by the lack of reference values, and high-quality radiographs still play a role although the evaluation ...

    • Qualitative Evaluations of mHealth Interventions: Current Gaps and Future Directions 

      Bradway, Meghan; Leibowitz, Kari; Garrison, Kathleen A.; Howe, Lauren; Årsand, Eirik (Journal article; Tidsskriftartikkel; Peer reviewed, 2020)
      Psycho-social factors are often addressed in behavioral health studies. While the purpose of many mHealth interventions is to facilitate behavior change, the focus is more prominently on the functionality and usability of the technology and less on the psycho-social factors that contribute to behavior change. Here we aim to identify the extent to which mHealth interventions for patient self- management ...

    • Plasma levels of growth differentiation factor 15 are associated with future risk of venous thromboembolism 

      Hansen, Ellen-Sofie; Hindberg, Kristian; Latysheva, Nadezhda; Aukrust, Pål; Ueland, Thor; Hansen, John-Bjarne; Brækkan, Sigrid Kufaas; Morelli, Vania Maris (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-15)
      Growth differentiation factor 15 (GDF-15), a marker of inflammation and oxidative stress, has emerged as a biomarker for arterial cardiovascular disease. However, the association between GDF-15 and venous thromboembolism (VTE) remains uncertain. We therefore investigated the association between plasma GDF-15 levels and future risk of incident VTE and explored the potential of a causal association ...

Wefound increased scores in all nine subscales of SCL-90-R, particularly phobic anxiety, depression and somatization. Further, patients reported considerably lower scores in all RAND-36 domains. This study revealed a ...
    • Novel bio-compatible tracers for Positron Emission Particle Tracking 

      Chang, Yu-Fen; Balakin, Boris (Conference object; Konferansebidrag, 2020-09)
      To study the flow of objects (tracers) in opaque flow processes, the PEPT (positron emission particle tracking) technique is utilized. The PEPT technique is based on the same principle of PET (positron emission tomography) which detects the characteristic back-to-back gamma pairs caused by positron-electron annihilation. The annihilation takes place within a few millimeters around the tracers labeled ...
