    • CTLA-4 expression in the non-small cell lung cancer patient tumor microenvironment: diverging prognostic impact in primary tumors and lymph node metastases 

      Paulsen, Erna-Elise; Kilvær, Thomas Karsten; Rakaee, Mehrdad; Richardsen, Elin; Hald, Sigurd; Andersen, Sigve; Busund, Lill-Tove; Bremnes, Roy M.; Dønnem, Tom (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-13)
      The immune checkpoint receptor CTLA-4 plays a crucial part in negatively regulating T cell activation and maintaining self-tolerance. It is frequently overexpressed in a variety of malignancies, yet its prognostic impact in non-small cell lung cancer (NSCLC) remains unclear. We constructed tissue microarrays from tumor tissue samples and evaluated the immunohistochemical expression of CTLA-4 in 536 ...

    • Culture-negative early-onset neonatal sepsis - at the crossroad between efficient sepsis care and antimicrobial stewardship 

      Klingenberg, Claus; Kornelisse, Rene F.; Buonocore, Giuseppe; Maier, Rolf F.; Stocker, Martin (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-09)
      Sepsis is a leading cause of mortality and morbidity in neonates. Presenting clinical symptoms are unspecific. Sensitivity and positive predictive value of biomarkers at onset of symptoms are suboptimal. Clinical suspicion therefore frequently leads to empirical antibiotic therapy in uninfected infants. The incidence of culture confirmed early-onset sepsis is rather low, around 0.4–0.8/1000 term ...

    • 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 ...

    • Curriculum factors influencing knowledge of communication skills among medical students 

      Bærheim, Anders; Anvik, Tor; Risberg, Terje; Hjortdahl, Per; Holen, Are; Fasmer, Ole Bernt; Grimstad, Hilde; Gude, Tore; Vaglum, Per (Journal article; Tidsskriftartikkel; Peer reviewed, 2007-10-10)
      Background: Communication training builds on the assumption that understanding of the concepts related to professional communication facilitates the training. We know little about whether students' knowledge of clinical communication skills is affected by their attendance of communication training courses, or to what degree other elements of the clinical training or curriculum design also play a ...

    • Cut-off values of serum potassium and core temperature at hospital admission for extracorporeal rewarming of avalanche victims in cardiac arrest: A retrospective multi-centre study 

      Brugger, Hermann; Bouzat, Pierre; Pasquier, Mathieu; Mair, Peter; Fieler, Julia; Darocha, Tomasz; Blancher, Marc; de Riedmatten, Matthieu; Falk, Markus; Paal, Peter; Strapazzon, Giarcome; Zafren, Ken; Maeder, Monika Brodmann (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06)
      Aim: Evidence of existing guidelines for the on-site triage of avalanche victims is limited and adherence suboptimal. This study attempted to find reliable cut-off values for the identification of hypothermic avalanche victims with reversible out-of-hospital cardiac arrest (OHCA) at hospital admission. This may enable hospitals to allocate extracorporeal life support (ECLS) resources more appropriately ...

      Ben-Batalla, Isabel; Cubas-Cordova, Miguel; Udonta, Florian; Wroblewski, Mark; Waizenegger, Jonas S.; Janning, Melanie; Sawall, Stefanie; Gensch, Victoria; Zhao, Lin; Martinez, Inigo Zubiavrre; Riecken, Kristoffer; Fehse, Boris; Pantel, Klaus; Bokemeyer, Carsten; Loges, Sonja (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-01-31)
      Anti-angiogenic therapies were approved for different cancers. However, significant primary and secondary resistance hampers efficacy in several tumor types including breast cancer. Thus, we need to develop clinically applicable strategies to enhance efficacy of anti-angiogenic drugs. We report that anti-angiogenic therapies can induce upregulation of cyclooxygenase-2 (Cox-2) and of its product ...

      Pottel, Hans; Björk, Jonas; Rule, Andrew D.; Ebert, Natalie; Eriksen, Bjørn Odvar; Dubourg, Laurence; Vidal-Petiot, Emmanuelle; Grubb, Anders; Hansson, Magnus; Lamb, Edmund J.; Littmann, Karin; Mariat, Christophe; Melsom, Toralf; Schaeffner, Elke; Sundin, Per-Ola; Åkesson, Anna; Larsson, Anders; Cavalier, Etienne; Bukabau, Justine B.; Sumaili, Ernest K.; Yayo, Eric; Monnet, Dagui; Flamant, Martin; Nyman, Ulf; Delanaye, Pierre (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-26)
      BACKGROUND - The accuracy of estimation of kidney function with the use of routine metabolic tests, such as measurement of the serum creatinine level, has been controversial. The European Kidney Function Consortium (EKFC) developed a creatinine-based equation (EKFC eGFRcr) to estimate the glomerular filtration rate (GFR) with a rescaled serum creatinine level (i.e., the serum creatinine level is ...

    • Cytokine concentrations are related to level of mental distress in inpatients not using anti-inflammatory drugs 

      Toft, Helge Prytz; Lien, Lars; Neupane, Sudan Prasad; Abebe, Dawit Shawel; Tilden, Terje; Wampold, Bruce E.; Bramness, Jørgen G. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-02)
      <p><i>Objective - </i>Cross-sectional data show elevated levels of circulating cytokines in psychiatric patients. The literature is divided concerning anti-inflammatory drugs’ ability to relieve symptoms, questioning a causal link between inflammatory pathways and psychiatric conditions. We hypothesised that the development of circulating cytokine levels is related to mental distress, and that this ...

      Siljan, William Ward; Holter, Jan Cato; Nymo, Ståle Haugset; Husebye, Einar; Ueland, Thor; Aukrust, Pål; Mollnes, Tom Eirik; Heggelund, Lars (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-24)
      Background:<br> The inflammatory response to community-acquired pneumonia (CAP) is orchestrated through activation of cytokine networks and the complement system. We examined the association of multiple cytokines and the terminal complement complex (TCC) with microbial aetiology, disease severity and shortterm outcome.<br> Materials and methods: <br>Plasma levels of 27 cytokines and TCC were ...

    • Cytomegalovirus-SpecificImmunoglobulin G is associated with chronic lung disease in children and adolescents from sub-Saharan Africa with perinatal HIV infection 

      Bowen, Dan Hameiri; Sovershaeva, Evgeniya; Charlton, Bethany; Schive, Cecilie; Odland, Jon Øyvind; McHugh, Grace; Bandason, Tsitsi; Mayin, Justin; Ferrand, Rashida A.; Yindom, Louis-Marie; Rowland-Jones, Sara L. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-26)
      In a cross-sectional study of 296 children and adolescents from Zimbabwe living with perinatal human immunodeficiency virus, individuals with the top tertile of cytomegalovirus-specific immunoglobulin G titer had an increased odds of chronic lung disease (odds ratio, 3.33; 95% confidence interval, 1.37–8.85; P = .010).

    • D-dimer as a stand-alone test to rule out deep vein thrombosis 

      Rinde, Fridtjof Balteskard; Frønæs, Synne Grønvold; Ghanima, Waleed Khalid; Vik, Anders; Hansen, John-Bjarne; Brækkan, Sigrid (Journal article; Tidsskriftartikkel, 2020-04-25)
      Background - Current guidelines recommend the use of clinical decision rules, such as Wells score, in combination with D-dimer to assess the need for objective imaging to rule out deep vein thrombosis (DVT). However, the clinical decision rule has limitations, and use of D-dimer as a stand-alone test has been suggested.<p> <p>Objective - We aimed to assess the safety and efficiency of D-dimer as ...

    • D-Dimer Measured at Diagnosis of Venous Thromboembolism is Associated with Risk of Major Bleeding 

      Johnsen, Håkon Sandbukt; Hindberg, Kristian; Bjøri, Esben; Brodin, Ellen Elisabeth; Brækkan, Sigrid Kufaas; Morelli, Vania Maris; Hansen, John-Bjarne (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-25)
      Identification of patients at risk of major bleeding is pivotal for optimal management of anticoagulant therapy in venous thromboembolism (VTE). Studies have suggested that D-dimer may predict major bleeding during anticoagulation; however, this is scarcely investigated in VTE patients. We aimed to investigate the role of D-dimer, measured at VTE diagnosis, as a predictive biomarker of major bleeding. ...

    • D-Dimer Measured At First Venous Thromboembolism Is Associated With Future Risk Of Cancer 

      Gran, Olga Vikhammer; Brækkan, Sigrid Kufaas; Paulsen, Benedikte; Skille, Hanne; Hansen, John-Bjarne (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-12)
      D-dimer >5000 ng/ml at incident VTE is associated with a higher risk of subsequent cancer within one and two years. High D-dimer levels are also associated with more aggressive tumor biology and poor prognosis in these patients. As D-dimer is routinely measured in the assessment of suspected VTE, it may be a useful surrogate marker for the presence of an underlying malignancy. Our findings may suggest ...

    • Data on the relation between renal biomarkers and measured glomerular filtration rate 

      Pottel, Hans; Dubourg, Laurence; Schaeffner, Elke; Eriksen, Bjørn Odvar; Melsom, Toralf; Lamb, Edmund J.; Rule, Andrew D.; Turner, Stephen T; Glassock, Richard J.; De Souza, Vandrea; Selistre, Luciano; Goffin, Karolien; Pauwels, Steven; Mariat, Christophe; Flamant, Martin; Bevc, Sebastjan; Delanaye, Pierre; Ebert, Natalie (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10)
      The data presented in this article are related to the research article entitled “The Diagnostic Value of Rescaled Renal Biomarkers Serum Creatinine and Serum Cystatin C and their Relation with Measured Glomerular Filtration Rate” (Pottel et al. (2017) [1]). Data are presented demonstrating the rationale for the normalization or rescaling of serum cystatin C, equivalent to the rescaling of serum ...

    • Data work in healthcare: An Introduction 

      Bossen, Claus; Pine, Katie; Cabitza, Federico; Ellingsen, Gunnar; Piras, Enrico Maria (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-12)
      Why data work in healthcare?<p> <p>Healthcare organizations across the globe are currently grappling to implement tools and practices to transform data from “refuse to riches,” a movement propelled by mass adoption of electronic health records (EHRs), sensors, and servers that can hold an ever-expanding volume of digital data. Allegedly, “By digitizing, combining and effectively using big data, ...
