      Øie, Cristina Ionica; Appa, Rupa Shree; Brodin, Ellen; Hilden, Ida; Smedsrød, Bård; Hansen, John-Bjarne (Journal article; Tidsskriftartikkel, 2010)
      Background: Tissue factor pathway inhibitor (TFPI) plays an important role for the anticoagulant effect of heparin. Depletion of intravascular TFPI by treatment with unfractionated heparin (UFH), and not by low molecular weight heparin (LMWH), has been suggested to explain the superiority of LMWH in treatment of both arterial and venous thrombosis. The present study was undertaken to investigate ...

    • Use of Health care in the main area of Sami habitation in Norway : catching up with national expenditure rates 

      Gaski, Margrete; Melhus, Marita; Deraas, Trygve Sigvart; Førde, Olav Helge (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      For many years political and professional concerns have centred on the health service access of Norway’s modern Indigenous Sami people. Thirty years ago, a study determined that a low rate of health expenditure on Sami patients had lead to inferior health services for the Sami people, with their average consultation rate 6 times lower than the Norwegian national average. Since 1980, there have been ...
