      We developed three ultra-high pressure liquid chromatography coupled to mass spectrometry detection (UHPLCMS/MS) methods to quantify 25 antihypertensive drugs in serum samples. Patient-reported drug lists were collected, and drug concentrations were analysed in samples from 547 patients, half with uncontrolled hypertension, and all treated with ≥ 2 antihypertensive drugs. For sample preparation, ...
    • Intravenous thrombolytic treatment and endovascular thrombectomy for ischaemic wake-up stroke 

      Roaldsen, Melinda Berg; Lindekleiv, Haakon; Mathiesen, Ellisiv B. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-01)
      <b><p>Background</b> About one in five strokes occur during sleep (wake-up stroke). People with wake-up strokes have previously been considered to be ineligiblefor thrombolytic treatment because the time of stroke onset is unknown. However, recent studies suggest benefit from recanalisationtherapies in selected patients. <b><p>Objectives</b> To assess the effects of intravenous thrombolysis ...

    • Urinary orosomucoid is associated with diastolic dysfunction and carotid arteriopathy in the general population. Cross-sectional data from the Tromsø study 

      Andreassen, Runa Marie; Kronborg, Jens; Schirmer, Henrik; Mathiesen, Ellisiv B.; Melsom, Toralf; Eriksen, Bjørn Odvar; Jenssen, Trond Geir; Solbu, Marit Dahl (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-02)
      Objectives. Urinary albumin excretion is a risk marker for cardiovascular disease (CVD). Studies suggest that urinary orosomucoid may be a more sensitive marker of general endothelial dysfunction than albuminuria. The aim of this population-based cross-sectional study was to examine the associations between urinary orosomucoid to creatinine ratio (UOCR), urinary albumin to creatinine ratio ...

    • Comparability of plasma iohexol clearance across population-based cohorts 

      Eriksen, Bjørn Odvar; Schaeffner, Elke; Melsom, Toralf; Ebert, Natalie; van der Giet, Markus; Gudnason, Vilmundur; Indridasson, Olafur S.; Karger, Amy B.; Levey, Andrew S.; Schuchardt, Mirjam; Sørensen, Liv Karin; Pálsson, Runólfur (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-23)
      Rationale & Objective: Glomerular filtration rate (GFR) estimation based on creatinine or cystatin C level is currently the standard method for assessing GFR in epidemiologic research and clinical trials despite several important and well-known limitations. Plasma iohexol clearance has been proposed as an inexpensive method for measuring GFR that could replace estimated GFR in many research ...
    • Misinformation about Covid-19 Vaccines on Social Media: Rapid Review 

      Skafle, Ingjerd; Nordahl-Hansen, Anders; Quintana, Daniel; Wynn, Rolf; Gabarron, Elia (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-04)
      Background: The development of COVID-19 vaccines has been crucial in fighting the pandemic. However, misinformation about the COVID-19 pandemic and vaccines is spread on social media platforms at a rate that has made the World Health Organization coin the phrase infodemic. False claims about adverse vaccine side effects, such as vaccines being the cause of autism, were already considered a threat ...
    • A Novel Porcine Model of Ischemia-Reperfusion Injury After Cross-Clamping the Thoracic Aorta Revealed Substantial Cardiopulmonary, Thromboinflammatory and Biochemical Changes Without Effect of C1-Inhibitor Treatment 

      Nielsen, Erik Waage; Miller, Yoav; Brekke, Ole Lars; Grond, Joost; Duong, Anh Hoang; Fure, Hilde; Ludviksen, Judith K; Pettersen, Kristin; Reubsaet, Leon; Solberg, Rigmor; Johansen, Harald Thidemann; Mollnes, Tom Eirik (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-01)
      Ischemic injury worsens upon return of blood and innate immunity including the complement system play a central role in ischemia-reperfusion injury (IRI) as in thoracic aortic surgery. Complement component1 inhibitor (C1-INH) has been shown to reduce IRI and is a broad-acting plasma cascade inhibitor. We established a new porcine model of IRI by cross-clamping the thoracic aorta and evaluated the ...

      Jensen, Søren Beck; Latysheva, Nadezhda; Hindberg, Kristian; Ueland, Thor (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-14)
      Background<p> <p>Effect-size underestimation impedes biomarker identification. Long follow-up time in prospective studies attenuates effect-size estimates for transient biomarkers, while disease category–specific biomarkers are affected by merging of categories. Venous thromboembolism (VTE) encompasses deep vein thrombosis (DVT) and pulmonary embolism (PE). <p>Objectives <p>(i) To re-analyze untargeted ...

      Benevenuto, Rafael Fonseca; Venter, Hermoine Jean; Zanatta, Caroline Bedin; Nodari, Rubens Onofre; Agapito-Tenfen, Sarah Zanon (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-04)
      Background: International agreements and domestic legislation regulate genetically modified (GM) crops for environmental release, recognizing that genetic engineering could result in unintended genotypic and phenotypic effects. In that context, omics technologies, which allow comprehensive characterization of the molecular profile of GM crops at all levels, may be used to assess alterations or ...

      Background - Little data exists on the prevalence of chronic kidney disease (CKD) in the Russian population. We aimed to estimate the prevalence of CKD in a population-based study in Russia, compare with a similar study in Norway, and investigate whether differences in risk factors explained between-study differences in CKD.<p> <p>Methods - We compared age- and sex-standardised prevalence of ...
    • Association between brain-derived neurotropic factor (BDNF), high-sensitivity C-reactive protein (hs-CRP) and psychiatric symptoms in medicated and unmedicated patients 

      Soløy-Nilsen, Hedda; Nygård-Odeh, Kristin; Kristiansen, Magnhild Gangsøy; Brekke, Ole Lars; Mollnes, Tom Eirik; Reitan, Solveig Merete Klæbo; Øiesvold, Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-03)
      Background - There is evidence that brain-derived neurotropic factor (BDNF) plays a protective role in the brain. Peripheral levels of BDNF correlate with its concentration in the brain. Previous studies have revealed lower serum BDNF levels in patients with mental illnesses. In most studies serum BDNF correlates negatively with psychiatric disorders and disease severity. Most studies in this field ...
    • Association between cannabis use and physical health problems in Norwegian adolescents: a cross-sectional study from the youth survey Ungdata 

      Mæland, Ragnhild; Lien, Lars; Leonhardt, Marja (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-06)
      Background - Cannabis use is increasing among young Norwegians and several studies show a high incidence of common physical health problems. An association has previously been found between cannabis use and mental health problems. Since physical and mental health problems often co-occur, the aim of this study is to explore the relationship between cannabis use and physical health problems.<p> <p>Methods ...
