      Kontsevaya, Anna; Bates, Katie; Schirmer, Henrik; Bobrova, Natalia; Leon, David A.; McKee, Martin (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-23)
      <i>Objective</i> - Russia has one of the highest cardiovascular mortality rates. Modernisation of the Russian health system has been accompanied by a substantial increase in uptake of percutaneous coronary intervention (PCI), which substantially reduces the risk of mortality in patients with acute ST-elevation myocardial infarction (STEMI). This paper aims to describe contemporary Hospital treatment ...
    • Platelet count and risk of major bleeding in venous thromboembolism 

      Johnsen, Håkon Sandbukt; Brækkan, Sigrid Kufaas; Morelli, Vania Maris; Hansen, John-Bjarne (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-05)
      <p>The relationship between platelet count and risk of major bleeding in patients with venous thromboembolism (VTE) during anticoagulation remains unclear. We therefore investigated the association between platelet count, measured at VTE diagnosis and before the thrombotic event, and risk of major bleeding. Participants comprised 744 patients with incident VTE derived from the Tromsø Study. Major ...
    • Infection prevention guidelines and considerations for paediatric risk groups when reopening primary schools during COVID-19 pandemic, Norway, April 2020 

      Johansen, Tone Bjordal; Astrup, Elisabeth; Jore, Solveig; Nilssen, Hege; Dahlberg, Bente Barton; Klingenberg, Claus; Berg, AreStuwitz; Greve-Isdahl, Margrethe (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-04)
      In response to the coronavirus disease (COVID-19) pandemic, most countries implemented school closures. In Norway, schools closed on 13 March 2020. The evidence of effect on disease transmission was limited, while negative consequences were evident. Before reopening, risk-assessment for paediatric risk groups was performed, concluding that most children can attend school with few conditions requiring ...

      <i>Context</i> - Over the last decade, vitamin D has emerged as a risk determinant for type 2 diabetes and vitamin D supplementation has been hypothesized as a potential intervention to lower diabetes risk. Recently, several trials have reported on the effect of vitamin D supplementation on diabetes prevention in people with prediabetes.<p> <p><i>Evidence Acquisition</i> - A comprehensive literature ...
    • Digitally quantified CD8+ cells: the best candidate marker for an immune cell score in non-small cell lung cancer? 

      Paulsen, Erna-Elise; Andersen, Sigve; Rakaee, Mehrdad; Bremnes, Roy M.; Rasmussen Busund, Lill-Tove; Dønnem, Tom (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-09)
      The TNM classification is well established as a state-of-the-art prognostic and treatment-decision-making tool for non-small cell lung cancer (NSCLC) patients. However, incorporation of biological data may hone the TNM system. This article focuses on choosing and incorporating subsets of tissue-infiltrating lymphocyte (TIL), detected by specific immunohistochemistry and automatically quantified by ...

      <p><i>Background - </i>Surgery on extraforaminal lumbar disc herniation (ELDH) is a commonly performed procedure. Operating on this type of herniation is known to come with more difficulties than on the frequently seen paramedian lumbar disc herniation (PLDH). However, no comparative data are available on the effectiveness and safety of this operation. We sought out to compare clinical outcomes at ...

      Butola, Ankit; Popova, Daria; Prasad, Dilip K.; Ahmad, Azeem; Habib, Anowarul; Tinguely, Jean-Claude; Basnet, Purusotam; Acharya, Ganesh; Paramasivam, Senthilkumaran; Mehta, Dalip Singh; Ahluwalia, Balpreet Singh (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-04)
      Sperm cell motility and morphology observed under the bright field microscopy are the only criteria for selecting a particular sperm cell during Intracytoplasmic Sperm Injection (ICSI) procedure of Assisted Reproductive Technology (ART). Several factors such as oxidative stress, cryopreservation, heat, smoking and alcohol consumption, are negatively associated with the quality of sperm cell and ...
    • Genetic interaction between the non‐homologous end joining factors during B and T lymphocyte development: in vivo mouse models 

      Castaneda Zegarra, Sergio Miguel; Fernandez Berrocal, Marion Silvana; Tkachev, Max; Yao, Rouan; Esnardo Upfold, Nikki Lyn; Oksenych, Valentyn (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-12)
      Non‐homologous end joining (NHEJ) is the main DNA repair mechanism for the repair of double‐strand breaks (DSBs) throughout the course of the cell cycle. DSBs are generated in developing B and T lymphocytes during V(D)J recombination to increase the repertoire of B and T cell receptors. DSBs are also generated during the class switch recombination (CSR) process in mature B lymphocytes, providing ...
    • The Master Study in Telemedicine and E-health at the University of Tromsø, Norway, 2005-2018 

      Wynn, Rolf; Ellingsen, Gunnar (Journal article; Tidsskriftartikkel; Peer reviewed, 2020)
      In this paper we describe the Master Study in Telemedicine and E-health at the University of Tromsø, Norway. The study enrolled its first students in 2005 and was closed in 2018. We describe and discuss the background of the programme, its development and accomplishments and why it was closed. Hopefully, this narrative will be of use to other programmes focusing on e-health.
    • Serum PTH is not a good marker for defining a threshold for vitamin D deficiency 

      Jorde, Rolf; Grimnes, Guri (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-01)
      <i>Objective</i>: In addition to its skeletal effects, vitamin D may also be important for health in general. It is uncertain what level of serum 25-hydroxyvitamin D (25(OH)D), marker of vitamin D status, is sufficient for these effects. With decreasing serum 25(OH)D levels there is an increase in serum PTH. The point at which this occurs has been considered as a threshold for vitamin D sufficiency. ...

      Kumsars, Indulis; Holm, Niels Ramsing; Niemelä, Matti; Erglis, Andrejs; Kervinen, Kari; Kervinen, Evald Høj; Maeng, Michael; Dombrovskis, Andis; Abraitis, Vytautas; Kibarskis, Aleksandras; Trovik, Thor; Latkovskis, Gustavs; Sondore, Dace; Narbute, Inga; Juhl Terkelsen, Christian; Eskola, Markko; Romppanen, Hannu; Laine, Mika; Jensen, Lisette Okkels; Pietila, Mikko; Gunnes, Pål; Hebsgaard, Lasse; Frobert, Ole; Calais, Fredrik; Hartikainen, Juha; Aarøe, Jens; Ravkilde, Jan; Engstrøm, Thomas; Steigen, Terje K.; Thuesen, Leif; Lassen, Jens F. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-19)
      <i>Background</i> - It is still uncertain whether coronary bifurcations with lesions involving a large side branch (SB) should be treated by stenting the main vessel and provisional stenting of the SB (simple) or by routine two-stent techniques (complex). We aimed to compare clinical outcome after treatment of lesions in large bifurcations by simple or complex stent implantation.<p> <p><i>Methods</i> ...

    • A Survey on Cannabinoid Treatment of Pediatric Epilepsy Among Neuropediatricians in Scandinavia and Germany 

      Klingenberg, Claus; Mouslet, George; Hjalgrim, Helle; Gerstner, Thorsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-24)
      <i>Objectives</i>: There is an increasing interest in cannabinoid-based products for the treatment of refractory pediatric epilepsy. However, a licensed cannabidiol (CBD) product was first approved for use by the European regulatory authorities in 2019. We aimed to obtain knowledge about clinical experience and attitudes toward cannabinoid use for epilepsy treatment among neuropediatricians in ...
    • Room tilt illusion and subclavian steal - A case report

    • Increased calcium intake is associated lower serum 25-hydroxyvitamin D levels in subjects with adequate vitamin D intake: a population-based observational study 

      Jorde, Rolf; Grimnes, Guri (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-02)
      <i>Background</i> - There are indications that an increased intake of calcium has a vitamin D sparing effect, which might be explained by a decreased catabolism of 25-hydroxyvitamin D (25(OH)D). However, there are only a few studies where this has been examined.<p> <p><i>Method</i> - In the seventh survey of the Tromsø study, serum 25(OH)D and parathyroid hormone were measured, and questionnaires ...
