      Brun, Vegard Heimly; Eriksen, Amund H.; Selseth, Ruth; Johansson, Kenth; Vik, Renate; Davidsen, Benedicte; Kaut, Michal; Hellemo, Lars (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-07)
      Background: After seven decades of levothyroxine (LT4) replacement therapy, dosage adjustment still takes several months. We have developed a decision aid tool (DAT) that models LT4 pharmacometrics and enables patient-tailored dosage. The aim of this was to speed up dosage adjustments for patients after total thyroidectomy.<p> <p>Methods: The DAT computer program was developed with a group of 46 ...

    • Estimated Glomerular Filtration Rate (eGFR) based on cystatin C was associated with increased risk of hip and proximal humerus fractures in women and decreased risk of hip fracture in men, whereas eGFR based on creatinine was not associated with fracture risk in both sexes: The Tromsø Study 

      Nordvåg, Sofie; Solbu, Marit Dahl; Melsom, Toralf; Nissen, Frida Igland; Andreasen, Camilla; Borgen, Tove Tveitan; Eriksen, Bjørn Odvar; Joakimsen, Ragnar Martin; Bjørnerem, Åshild (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-14)
      <i>Purpose</i> - Patients with end-stage kidney disease have an increased fracture risk. Whether mild to moderate reductions in kidney function is associated with increased fracture risk is uncertain. Results from previous studies may be confounded by muscle mass because of the use of creatinine-based estimates of the glomerular filtration rate (eGFRcre). We tested the hypothesis that lower eGFR ...

      Caglayan, Hatice Akay; Kjønås, Didrik; Malm, Siri; Schirmer, Henrik; Røsner, Assami (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-28)
      Background - The 2016 guidelines of the American Society of Echocardiography (ASE) and European Association of Cardiovascular Imaging (EACVI) for evaluation of left ventricular (LV) diastolic dysfunction by Doppler flow and tissue Doppler- echocardiography do not adjust assessment of high filling pressures for patients with aortic stenosis (AS). However, most of the studies on this patient group ...
    • Plasma levels of von Willebrand factor and future risk of incident venous thromboembolism 

      Edvardsen, Magnus; Hindberg, Kristian; Hansen, Ellen-Sofie; Morelli, Vania Maris; Ueland, Thor; Aukrust, Pål; Brækkan, Sigrid Kufaas; Holtet Evensen, Line; Hansen, John-Bjarne (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-07)
      Several case-control studies have reported elevated plasma von Willebrand factor (VWF) levels in patients with venous thromboembolism (VTE) compared with controls. However, because few studies have investigated the association in a prospective design, it is unclear whether elevated plasma VWF is a risk factor or a consequence of the VTE event. Therefore, we aimed to investigate the prospective ...

    • Cardiovascular Effects of Epinephrine During Experimental Hypothermia (32°C) With Spontaneous Circulation in an Intact Porcine Model 

      Mohyuddin, Rizwan; Dietrichs, Erik Sveberg; Sundaram, Predip; Kondratiev, Timofei V.; Figenschou, Marie Fjellanger; Sieck, Gary C.; Tveita, Torkjel (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-06)
      <i>Aims</i>: Rewarming from accidental hypothermia and therapeutic temperature management could be complicated by cardiac dysfunction. Although pharmacologic support is often applied when rewarming these patients, updated treatment recommendations are lacking. There is an underlying deficiency of clinical and experimental data to support such interventions and this prevents the development of clinical ...

      Ronessen Pain, Maria; Wolden, Runa; Jaén-Luchoro, Daniel; Salvà-Serra, Francisco; Iglesias, Beatriz Piñeiro; Karlsson, Roger; Klingenberg, Claus; Cavanagh, Jorunn Pauline (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-13)
      When analysing a large cohort of Staphylococcus haemolyticus , using whole-genome sequencing, five human isolates (four from the skin and one from a blood culture) with aberrant phenotypic and genotypic traits were identified. They were phenotypically similar with yellow colonies, nearly identical 16S rRNA gene sequences and initially speciated as S. haemolyticus based on 16S rRNA gene sequence and ...
    • Clinical manifestations and novel pathogenic variants in SOX10 in eight Danish probands with Waardenburg syndrome 

      Moldenæs, Marika F.; Rendtorff, Nanna D.; Hindbæk, Lone S.; Tørring, Pernille M.; Nilssen, Øivind; Tranebjærg, Lisbeth (Journal article; Tidsskriftartikkel; Peer reviewed; Master thesis; Mastergradsoppgave, 2021-06-22)
      The SRY-related HMG box gene 10 (SOX10), located on 22q13.1, encodes a member of the SOX family of transcription factors involved in the regulation of embryonic development and in the determination of cell fate and differentiation. SOX10 is one of the six causal genes for Waardenburg syndrome, which is a dominantly inherited auditory-pigmentary disorder characterized by sensorineural hearing impairment ...
    • Secretion rates and protein composition of extracellular vesicles released by cancer-associated fibroblasts after radiation 

      Berzaghi, Rodrigo; Islam, Md Ashraful; Hellevik, Turid; Martinez-Zubiaurre, Inigo (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-24)
      Reciprocal communication between the malignant and non-malignant cellular elements in tumors is essential for cancer sustainability and plays an important role in the response of cancers to treatments. Some of this cellular crosstalk takes place via secretion of vesicles that are actively released into the extracellular space by most cell types in tumors. Recent studies have demonstrated radiation-induced ...

      Børvik, Trond; Evensen, Line; Morelli, Vania Maris; Melbye, Hasse; Brækkan, Sigrid Kufaas; Hansen, John-Bjarne (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-09)
      Background: Chronic obstructive pulmonary disease (COPD) is associated with risk of venous thromboembolism (VTE). It remains unknown whether individual respiratory symptoms and lowered oxygen saturation (SpO<sub>2</sub>), individually and in combination with COPD, affect the risk of VTE.<p> <p> Objectives: To investigate whether measures of respiratory impairments including respiratory symptoms ...
