      Hansen, Ann Kristin; Indrevik, Jill-Tove; Figenschau, Yngve Anton; Martinez, Inigo Zubiavrre; Sveinbjørnsson, Baldur (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-02-09)
      Leukotriene B<sub>4</sub> (LTB<sub>4</sub>) is a potent chemoattractant associated with the development of osteoarthritis (OA), while its receptors BLT1 and BLT2 have been found in synovium and subchondral bone. In this study, we have investigated whether these receptors are also expressed by human cartilage cells and their potential effects on cartilage cells. The expression of LTB<sub>4</sub> ...
    • Changes in the human transcriptome upon vitamin D supplementation 

      Pasing, Yvonne; Fenton, Christopher Graham; Jorde, Rolf; Paulssen, Ruth H (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-03-19)
      Vitamin D is hydroxylated in the liver and kidneys to its active form, which can bind to the vitamin D receptor (VDR). The VDR is present in a wide variety of different cells types and tissues and acts as a transcription factor. Although activation of the VDR is estimated to regulate expression of up to 5% of the human genome, our study is the first analysing gene expression after supplementation ...
    • Outcomes in pancreas transplantation with exocrine drainage through a duodenoduodenostomy versus duodenojejunostomy 

      Lindahl, Jørn Petter Hanto; Horneland, Rune; Nordheim, Espen; Hartmann, Anders; Aandahl, Einar Martin; Grzyb, Krzysztof; Haugaa, Håkon; Kjøsen, Gisle; Åsberg, Anders; Jenssen, Trond Geir (Journal article; Tidsskriftartikkel, 2017-08-23)
      Until recently, pancreas transplantation has mostly been performed with exocrine drainage via duodenojejunostomy (DJ). Since 2012, DJ was substituted with duodenoduodenostomy (DD) in our hospital, allowing endoscopic access for biopsies. This study assessed safety profiles with DD versus DJ procedures and clinical outcomes with the DD technique in pancreas transplantation. DD patients (n = 117; 62 ...

This study will describe and compare outpatient clinics treating substance use disorders in Arkhangelsk in Northwest Russia and in Bodø and Tromsø in Northern Norway on availability, ...
    • Contemporary radiooncological management of bone metastases from breast cancer: factors associated with prescription of different fractionation regimens (short or long course) in a rural part of North Norway with long travel distance 

      Nieder, Carsten; Dalhaug, Astrid; Haukland, Ellinor; Mannsåker, Bård; Pawinski, Adam (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-01-19)
      The aim of this study was to reduce barriers that prevent implementation of evidence-based recommendations about single-fraction palliative radiotherapy (PRT) and to demonstrate that single-fraction PRT yields similar outcomes as long-course treatment (≥10 fractions) in patients with bone metastases from breast cancer. This retrospective study (2007–2014) included 118 Norwegian female patients. All ...
    • Impact of multi-professional, scenario-based training on postpartum hemorrhage in Tanzania: A quasi-experimental, pre- vs. post-intervention study 

      Egenberg, Signe; Masenga, Gileard; Bru, Lars Edvin; Eggebø, Torbjørn Moe; Mushi, Cecilia; Massay, Deodatus Amadeus; Øian, Pål (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-09-05)
      Background: <br> Tanzania has a relatively high maternal mortality ratio of 410 per 100,000 live births. Severe postpartum hemorrhage (PPH) is a major cause of maternal deaths, but in most cases, it is preventable. However, most pregnant women that develop PPH, have no known risk factors. Therefore, preventive measures must be offered to all pregnant women. This study investigated the effects ...

    • Regulation of TFPIα expression by miR-27a/b-3p in human endothelial cells under normal conditions and in response to androgens 

      Arroyo, Ana Belen V.; Salloum-Asfar, Salam; Pérez-Sánchez, Carlos; Teruel-Montoya, Raúl; Navarro, Silvia; García-Barberá, Nuria; Luengo-Gil, Ginés; Roldán, Vanessa; Hansen, John-Bjarne; Vicente, Vicente; Gónzález-Conejero, Rocío; Martínez, Constantino (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-02-27)
      The increased risk of cardiovascular events in older men is multifactorial, but the significant reduction of testosterone levels has been involved. As this hormone regulates the expression of TFPI by unknown mechanisms, we aimed to evaluate the role of miRNAs in the regulation of TFPIα expression under normal conditions and in response to androgens. In silico studies allowed the selection of 4 miRNAs ...

      The causal nature of the association between hypovitaminosis D and poor cognitive function in mid- to later-life is uncertain. Using a Mendelian randomisation(MR) approach, we examined the causal relationship between 25(OH)D and cognitive function. Data came from 172,349 participants from 17 cohorts. DHCR7(rs12785878), CYP2R1 rs12794714) and their combined synthesis score were chosen to proxy 25(OH)D. ...

      Holmøy, Trygve; Lindstrøm, Jonas Christoffer; Eriksen, Erik Fink; Steffensen, Linn Hofsøy; Kampman, Margitta Theodora (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-04-04)
      Background: <br> People with multiple sclerosis have high risk of osteoporosis and fractures. A poor vitamin D status is a risk factor for MS, and vitamin D supplementation has been recommended both to prevent MS progression and to maintain bone health. <br> Methods: <br> We assessed the effect of 20,000 IU vitamin D3 weekly compared to placebo on biochemical markers of bone metabolism in 68 ...
    • Blood pressure and age-related GFR decline in the general population 

      Eriksen, Bjørn Odvar; Stefansson, Vidar Tor Nyborg; Jenssen, Trond Geir; Mathisen, Ulla Dorte; Schei, Jørgen; Solbu, Marit Dahl; Wilsgaard, Tom; Melsom, Toralf (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-02-28)
      Background: <br> Hypertension is one of the most important causes of end-stage renal disease, but it is unclear whether elevated blood pressure (BP) also accelerates the gradual decline in the glomerular filtration rate (GFR) seen in the general population with increasing age. The reason may be that most studies have considered only baseline BP and not the effects of changes in BP, antihypertensive ...
    • Fat in the lumbar multifidus muscles - predictive value and change following disc prosthesis surgery and multidisciplinary rehabilitation in patients with chronic low back pain and degenerative disc: 2-year follow-up of a randomized trial
