    • BK polyomavirus evades innate immune sensing by disrupting the mitochondrial network and promotes mitophagy 

      Manzetti, Julia; Weissbach, Fabian H.; Graf, Fabrice E.; Unterstab, Gunhild; Wernli, Marion; Hopfer, Helmut; Drachenberg, Cinthia B.; Rinaldo, Christine Hanssen; Hirsch, Hans H. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-10)
      Immune escape contributes to viral persistence, yet little is known about human polyomaviruses. BK-polyomavirus (BKPyV) asymptomatically infects 90% of humans but causes premature allograft failure in kidney transplant patients. Despite virus-specific T cells and neutralizing antibodies, BKPyV persists in kidneys and evades immune control as evidenced by urinary shedding in immunocompetent individuals. ...

    • Metachronous Contralateral Testicular Cancer in the Cisplatin Era: A Population-Based Cohort Study 

      Hellesnes, Ragnhild; Myklebust, Tor Åge; Bremnes, Roy M.; Karlsdottir, Åsa; Kvammen, Øivind; Negaard, Helene Francisca Stigter; Tandstad, Torgrim; Wilsgaard, Tom; Fosså, Sophie Dorothea; Haugnes, Hege Sagstuen (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-23)
      PURPOSE - It is hypothesized that cisplatin-based chemotherapy (CBCT) reduces the occurrence of metachronous contralateral (second) germ cell testicular cancer (TC). However, studies including treatment details are lacking. The aim of this study was to assess the second TC risk, emphasizing the impact of previous TC treatment.<p> <p>PATIENTS AND METHODS - Based on the Cancer Registry of Norway, ...

    • Urinary excretion of epidermal growth factor and rapid loss of kidney function 

      Norvik, Jon Viljar; Harskamp, Laura R.; Nair, Viji; Shedden, Kerby; Solbu, Marit Dahl; Eriksen, Bjørn Odvar; Kretzler, Matthias; Gansevoort, Ron T.; Ju, Wenjun; Melsom, Toralf (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-17)
      Background - Lower urinary excretion of the kidney tubule–specific biomarker epidermal growth factor (uEGF) is associated with increased risk of renal function [glomerular filtration rate (GFR)] loss in diabetes and in patients with established chronic kidney disease (CKD). We investigated whether uEGF is associated with rapid GFR decline or incident CKD in the general population.<p> <p>Methods ...

    • User requirements meet large-scale EHR suites: Norwegian preparations for Epic 

      Ellingsen, Gunnar; Hertzum, Morten (Journal article; Tidsskriftartikkel; Peer reviewed, 2020)
      Electronic health records (EHRs) are becoming the norm in healthcare. Typically, these EHRs are large-scale suite systems. The up-front presence of ready-for-use EHR suites changes the role of user requirements and the conditions for deciding which requirements to include in the final contract. In this paper, we investigate how user requirements are negotiated in the ongoing preparations for the ...

      High blood cholesterol is typically considered a feature of wealthy western countries1,2. However, dietary and behavioural determinants of blood cholesterol are changing rapidly throughout the world3 and countries are using lipid-lowering medications at varying rates. These changes can have distinct effects on the levels of high-density lipoprotein (HDL) cholesterol and non-HDL cholesterol, which ...

      Background - The role of combined prothrombotic genotypes in cancer‐related venous thromboembolism (VTE) is scarcely studied. We aimed to investigate the impact of a 5‐single nucleotide polymorphism (SNP) score on the risk of VTE in patients with and without cancer using a population‐based case‐cohort.<p> <p>Methods - Cases with a first VTE (n = 1493) and a subcohort (n = 13 072) were derived ...

      In 2012, the Norwegian newborn screening program (NBS) was expanded (eNBS) from screening for two diseases to that for 23 diseases (20 inborn errors of metabolism, IEMs) and again in 2018, to include a total of 25 conditions (21 IEMs). Between 1 March 2012 and 29 February 2020, 461,369 newborns were screened for 20 IEMs in addition to phenylketonuria (PKU). Excluding PKU, there were 75 true-positive ...

      Nieder, Carsten; Dalhaug, Astrid; Pawinski, Adam (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-03)
      <p>Background/Aim: The aim of this study was to analyze the survival of patients with brain metastases treated with best supportive care or additional whole-brain radiotherapy (WBRT), in order to confirm results from the prospective randomized QUARTZ study, which suggested prolonged survival after WBRT (5 fractions of 4 Gy) if favorable prognostic factors were present (age younger than 60 years, ...

    • Symptom burden in patients with reduced performance status at the start of palliative radiotherapy 

      Nieder, Carsten; Kämpe, Thomas A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-28)
      <p>Background/Aim: Previous research has suggested that palliative radiotherapy is a useful measure, unless short survival reduces the time spent without active treatment, and in the case of a low likelihood of experiencing a net benefit in quality of life. Patients with reduced performance status (PS) may be especially at risk of futile treatment, despite having a relatively high symptom burden and ...

      Riaz, Misbah; Vangberg, Torgil Riise; Vasylenko, Olena; Castro Chavira, Susana Angelica; Gorecka, Marta Maria; Waterloo, Knut; Rodriguez-Aranda, Claudia (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-29)
      <i>Background</i> - White matter hyperintensities (WMH) are a common cerebral finding in older people. WMH are usually asymptomatic, but excessive WMH are associated with cognitive decline and dementia. WMH are also among the neurological findings most consistently associated with declining motor performance in healthy ageing.<br><br> <i>Aims</i> - To determine if WMH load is associated with ...

    • Non-Homologous End Joining Factors XLF, PAXX and DNA-PKcs Maintain the Neural Stem and Progenitor Cell Population 

      Gago-Fuentes, Raquel; Oksenych, Valentyn (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-28)
      Non-homologous end-joining (NHEJ) is a major DNA repair pathway in mammalian cells that recognizes, processes and fixes DNA damage throughout the cell cycle and is specifically important for homeostasis of post-mitotic neurons and developing lymphocytes. Neuronal apoptosis increases in the mice lacking NHEJ factors Ku70 and Ku80. Inactivation of other NHEJ genes, either <i>Xrcc4</i> or <i>Lig4</i>, ...

    • I don’t want to think about it: A qualitative study of children’s and parents’ experiences with regular needle injections at home 

      Sørensen, Kari; Skirbekk, Helge; Kvarstein, Gunnvald; Wøien, Hilde (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-22)
      <i>Background</i> - Overall outcomes of pediatric rheumatic diseases (RD) have improved due to treatment with biologic agents and methotrexate. For many children, this treatment often entails regular needle injections. Pain and fear of needle injections are common in childhood, but how children and parents handle long-term needle injections at home has not been fully explored. This study aimed to ...

    • The value of dynamic infrared thermography in pedicled thoracodorsal artery perforator flap surgery 

      Sjöberg, Thomas K.; Mercer, James; Weum, Sven; de Weerd, Louis (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-15)
      <p><i>Background:</i> Dynamic infrared thermography (DIRT) is a noninvasive imaging technique that can provide indirect and real-time information on skin perfusion by measuring skin temperature. Although used in flap surgery, there are no reports on its value in procedures using a pedicled thoracodorsal artery perforator (TDAP) flap. The aim of this study was to assess the usefulness of DIRT in ...

    • Epipericardial Fat Necrosis: A Case Report and a Review of the Literature 

      Mortensen, Synnøve Gjelsten; Buchmann, Petr; Lappegård, Knut Tore (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-16)
      Epipericardial fat necrosis (EFN), also known as pericardial or mediastinal fat necrosis, has until lately been considered an unusual cause of acute chest pain. Due to increased use of computed tomography (CT) and other imaging techniques, EFN is now believed to be an under-diagnosed cause of acute chest pain. We here present a patient with a short history of acute, left-sided pleuritic chest pain ...
