    • Dynamical models of mutated chronic myelogenous leukemia cells for a postimatinib treatment scenario: Response to dasatinib or nilotinib therapy 

      Woywod, Clemens Joachim; Gruber, Franz; Engh, Richard Alan; Flå, Tor (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-05)
      Targeted inhibition of the oncogenic BCR-ABL1 fusion protein using the ABL1 tyrosine kinase inhibitor imatinib has become standard therapy for chronic myelogenous leukemia (CML), with most patients reaching total and durable remission. However, a significant fraction of patients develop resistance, commonly due to mutated ABL1 kinase domains. This motivated development of second-generation drugs ...
    • Future complications of chronic hepatitis C in a low-risk area: Projections from the hepatitis c study in Northern Norway 

      Kileng, Hege; Bernfort, Lars; Gutteberg, Tore Jarl; Moen, Odd Sverre; Kristiansen, Magnhild Gangsøy; Paulssen, Eyvind Jakob; Berg, Leif Kyrre; Florholmen, Jon; Goll, Rasmus (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-09-16)
      <i>Background</i>: Hepatitis C (HCV) infection causes an asymptomatic chronic hepatitis in most affected individuals, which often remains undetected until cirrhosis and cirrhosis-related complications occur. Screening of high-risk subjects in Northern Norway has revealed a relatively low prevalence in the general population (0.24%). Despite this, late complications of HCV infection are increasing. ...

      Background:<br>A large number of observational studies have reported harmful effects of low 25-hydroxyvitamin D (25OHD) levels on non-skeletal outcomes. We performed a systematic quantitative review on characteristics of randomized clinical trials (RCTs) included in meta-analyses (MAs) on non-skeletal effects of vitamin D supplementation.<br>Methods and findings:<br>We identified systematic reviews ...
    • The association between anemia and falls in community-living women and men aged 65 years and older from the fifth Tromsø Study 2001-02: a replication study 

      Hopstock, Laila Arnesdatter; Utne, Elisabeth Bøe; Horsch, Alexander; Skjelbakken, Tove (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-12-27)
      Background: <br> Falls are common among elderly people, and the risk increase with age. Falls are associated with both health and social consequences for the patient, and major societal costs. Identification of risk factors should be investigated to prevent falls. Previous studies have shown anemia to be associated with increased risk of falling, but the results are inconsistent. The aim of this ...
    • Gene-centromere mapping in meiotic gynogenetic European seabass 

      Oral, Münevver; Colléter, Julie; Bekaert, Michaël; Taggart, John B.; Palaoikostas, Christos; McAndrew, Brendan J.; Vandeputte, Marc; Chatain, Béatrice; Kuhl, Heiner; Reinhardt, Richard; Peruzzi, Stefano; Penman, David J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-07)
      Background: <br> Fully isogenic lines in fish can be developed using “mitotic” gynogenesis (suppression of first zygotic mitosis following inactivation of the sperm genome). However, genome-wide verification of the steps in this process has seldom been applied. We used ddRADseq to generate SNP markers in a meiotic gynogenetic family of European seabass (Dicentrarchus labrax): (i) to verify the lack ...
    • Associations of brain-natriuretic peptide, high-sensitive troponin T, and high-sensitive C-reactive protein with outcomes in severe aortic stenosis 

      Auensen, Andreas; Hussain, Amjad; Falk, Ragnhild Sørum; Walle-Hansen, Marte Meyer; Bye, Jorun; Pettersen, Kjell; Ueland, Thor; Gullestad, Lars (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-12)
      Objectives:<br>Among patients with severe aortic stenosis (AS), we investigated the associations of N–terminal pro–natriuretic peptide (NT–proBNP), high–sensitive troponin T (hsTnT), and high–sensitive C–reactive protein (hs–CRP) with 3–year mortality and major adverse cardiovascular events (MACE) during 1 year.<br>Methods:<br>This observational cohort study prospectively enrolled 442 patients with ...
    • Bone mineral density is associated with Vitamin D related rs6013897 and estrogen receptor polymorphism rs4870044: The Tromsø study 

      Martinaityte, Ieva; Jorde, Rolf; Emaus, Nina; Eggen, Anne Elise; Joakimsen, Ragnar Martin; Kamycheva, Elena (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-03-02)
      Background:<br>Bone mineral density (BMD) is determined by bone remodeling processes regulated by endocrine, autocrine and genetic mechanisms. Thus, some studies have reported that BMD is associated with single nucleotide polymorphisms (SNPs) associated with vitamin D receptor (VDR), serum 25(OH)D levels and estrogen receptor 1 (ESR1), but without consensus. Therefore, we aimed to map and compare ...

      Bakke, Håkon Kvåle; Steinvik, Tine; Angell, Johan; Wisborg, Torben (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-02-23)
      Background: <br> Bystander first aid can improve survival following out-of-hospital cardiac arrest or trauma. Thus, providing first aid education to laypersons may lead to better outcomes. In this study, we aimed to establish the prevalence and distribution of first aid training in the populace, how often first aid skills are needed, and selfreported helping behaviour. <br> Methods: <br> We ...
    • Embodied uncertainty - Exploring sensorial and existential dimensions of everyday life after cancer 

      Seppola-Edvardsen, Tone (Doctoral thesis; Doktorgradsavhandling, 2017-11-14)
      In Norway, as in other countries in the northern hemisphere, an increasing number of people survive after cancer diagnosis and treatment. Earlier studies have shown that life after cancer can be challenging in different ways, which makes it important to gain knowledge about this group to be able to meet their needs in the future. The main objective of this project was to understand the illness ...
    • Current guidelines for BRCA testing of breast cancer patients are insufficient to detect all mutation carriers 

      Grindedal, Eli Marie; Heramb, Cecilie; Karsrud, Inga; Ariansen, Sarah Louise; Mæhle, Lovise Olaug; Undlien, Dag Erik; Norum, Jan; Schlichting, Ellen (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-21)
      Background: <br> Identification of BRCA mutations in breast cancer (BC) patients influences treatment and survival and may be of importance for their relatives. Testing is often restricted to women fulfilling high-risk criteria. However, there is limited knowledge of the sensitivity of such a strategy, and of the clinical aspects of BC caused by BRCA mutations in less selected BC cohorts. The aim ...
    • Vitamin D and mortality: Individual participant data meta-analysis of standardized 25-hydroxyvitamin D in 26916 individuals from a European consortium 

      Gaksch, Martin; Jorde, Rolf; Grimnes, Guri; Joakimsen, Ragnar Martin; Schirmer, Henrik; Wilsgaard, Tom; Mathiesen, Ellisiv B.; Njølstad, Inger; Løchen, Maja-Lisa; März, Winfried; Kleber, Marcus E.; Tomaschitz, Andreas; Grübler, Martin; Eiriksdottir, Gudny; Gudmundsson, Elias F.; Harris, Tamara B.; Cotch, Mary Frances; Aspelund, Thor; Gudnason, Vilmundur; Rutters, Femke; Beulens, Joline W.J.; Van't Riet, Esther; Nijpels, Giel; Dekker, Jacqueline M.; Grove-Laugesen, Diana; Rejnmark, Lars; Busch, Markus A.; Mensink, Gert B.M.; Scheidt-Nave, Christa; Thamm, Michael; Swart, Karin M.A.; Brouwer, Ingeborg A.; Lips, Paul; Van Schoor, Natasja M.; Sempos, Christopher T.; Durazo-Arvizu, Ramón A.; Škrabáková, Zuzana; Dowling, Kirsten G.; Cashman, Kevin D.; Kiely, Mairead; Pilz, Stefan (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-02-16)
      Background:<br>Vitamin D deficiency may be a risk factor for mortality but previous meta-analyses lacked standardization of laboratory methods for 25-hydroxyvitamin D (25[OH]D) concentrations and used aggregate data instead of individual participant data (IPD). We therefore performed an IPD meta-analysis on the association between standardized serum 25(OH)D and mortality.<br>Methods:<br>In a European ...
    • Fecal carriage of extended spectrum β-lactamase producing Escherichia coli and Klebsiella pneumoniae after urinary tract infection - A three year prospective cohort study 

      Jørgensen, Silje; Søraas, Arne Vasli; Sundsfjord, Arnfinn; Liestøl, Knut; Leegaard, Truls Michael; Jenum, Pål (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-03-07)
      We have performed a prospective cohort study to investigate the duration of and risk factors for prolonged fecal carriage of ESBL-producing Escherichia coli or Klebsiella pneumoniae in patients with community acquired urinary tract infection caused by these bacteria. From 2009 to 2011, 101 Norwegian patients were recruited. Stool swabs and questionnaires were collected every three months for one ...
    • Development and validation of the Efficacy Safety Score (ESS), a novel tool for postoperative patient management 

      Skraastad, Erlend Johan; Ræder, Johan; Dahl, Vegard; Bjertnæs, Lars J.; Kuklin, Vladimir (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-03-28)
      Background: <br> Several reports have shown that postoperative monitoring of general safety and quality issues, including pain treatment, after discharge from recovery is often non-systematic and inadequate. We suggest a new score with assessment of key recovery parameters, as a supportive tool for postoperative care and a call-out algorithm for need of extra help. The aim of this investigation ...
    • Low dose naltrexone in multiple sclerosis: Effects on medication use. A quasi-experimental study 

      Raknes, Guttorm; Småbrekke, Lars (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-03)
      Low dose naltrexone (LDN) has become a popular off-label therapy for multiple sclerosis (MS). A few small, randomized studies indicate that LDN may have beneficial effects in MS and other autoimmune diseases. If proven efficacious, it would be a cheap and safe alternative to the expensive treatments currently recommended for MS. We investigated whether a sudden increase in LDN use in Norway in 2013 ...
    • Does proximity of women to facilities with better choice of contraceptives affect their contraceptive utilization in rural Ethiopia? 

      Shiferaw, Solomon; Spigt, Mark; Seme, Assefa; Amogne, Ayanaw; Skrøvseth, Stein Olav; Desta, Selamawit; Radloff, Scott; Tsui, Amy; Dinant, Geert-Jan (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-13)
      Background:<br>There is limited evidence of the linkage between contraceptive use, the range of methods available and level of contraceptive stocks at health facilities and distance to facility in developing countries. The present analysis aims at examining the influence of contraceptive method availability and distance to the nearby facilities on modern contraceptive utilization among married women ...
    • Molecular and epidemiological characterization of carbapenemase-producing Enterobacteriaceae in Norway, 2007 to 2014 

      Samuelsen, Ørjan; Overballe-Petersen, Søren; Bjørnholt, Jørgen; Brisse, Sylvain; Doumith, Michel; Woodford, Neil; Hopkins, Katie L.; Aasnæs, Bettina; Haldorsen, Bjørg; Sundsfjord, Arnfinn (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-15)
      The prevalence of carbapenemase-producing Enterobacteriaceae (CPE) is increasing worldwide. Here we present associated patient data and molecular, epidemiological and phenotypic characteristics of all CPE isolates in Norway from 2007 to 2014 confirmed at the Norwegian National Advisory Unit on Detection of Antimicrobial Resistance. All confirmed CPE isolates were characterized pheno- and genotypically, ...
    • Activity of xyloglucan endotransglucosylases/hydrolases suggests a role during host invasion by the parasitic plant Cuscuta reflexa 

      Olsen, Stian; Krause, Kirsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-04-27)
      The parasitic vines of the genus Cuscuta form haustoria that grow into other plants and connect with their vascular system, thus allowing the parasite to feed on its host. A major obstacle that meets the infection organ as it penetrates the host tissue is the rigid plant cell wall. In the present study, we examined the activity of xyloglucan endotransglucosylases/hydrolases (XTHs) during the ...
    • Transcriptome analysis identifies key metabolic changes in the hooded seal (Cystophora cristata) brain in response to hypoxia and reoxygenation 

      Hoff, Mariana Leivas Müller; Fabrizius, Andrej; Czech-Damal, Nicole U.; Folkow, Lars; Burmester, Thorsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-01-03)
      The brain of diving mammals tolerates low oxygen conditions better than the brain of most terrestrial mammals. Previously, it has been demonstrated that the neurons in brain slices of the hooded seal (Cystophora cristata) withstand hypoxia longer than those of mouse, and also tolerate reduced glucose supply and high lactate concentrations. This tolerance appears to be accompanied by a shift in the ...
    • Limited grounding-line advance onto the West Antarctic continental shelf in the easternmost Amundsen Sea Embayment during the last glacial period 

      Klages, Johann Philipp; Kuhn, Gerhard; Hillenbrand, Claus-Dieter; Smith, James; Graham, Alastair G C; Nitsche, F. O.; Frederichs, Thomas; Jernas, Patrycja Ewa; Gohl, Karsten; Wacker, Lukas (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-25)
      Precise knowledge about the extent of the West Antarctic Ice Sheet (WAIS) at the Last Glacial Maximum (LGM; c. 26.5–19 cal. ka BP) is important in order to 1) improve paleo-ice sheet reconstructions, 2) provide a robust empirical framework for calibrating paleo-ice sheet models, and 3) locate potential shelf refugia for Antarctic benthos during the last glacial period. However, reliable reconstructions ...
    • A Cold Rain on the Parade When the Sámi Celebrate 100th Anniversary 

      Ravna, Øyvind (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-02-06)
      6 February 2017 marks the centenary of The First Sámi Congress, which is also the reason that we today celebrate the 6th of February as the Sámi National Day. The First Congress will be thoroughly celebrated in Trondheim where it originally took place. Such an anniversary naturally inspires reflection on what the Sámi have achieved in the years since Elsa Laula Renberg and other visionary Sámi leaders ...
