    • Acute psychiatric admissions from an out-of-hours Casualty Clinic. How do referring doctors and admitting specialists agree? 

      Deraas, Trygve Sigvart; Giæver, Anton; Hansen, Vidje; Olstad, Reidun (Journal article; Tidsskriftartikkel; Peer reviewed, 2006-03-29)
      Background: Over the last decades there has been an increasing pressure on the acute psychiatric wards in Norway. The major contributor to psychiatric acute admissions at the University Hospital of North Norway in the city of Tromsø in 2001 was the GP-based Tromsø Casualty Clinic, only open out-of-hours. We explored all acute psychiatric referrals from Tromsø Casualty Clinic in 2001. The purpose ...

    • Circular instead of hierarchical. Methodological principles for the evaluation of complex interventions 

      Walach, Harald; Fønnebø, Vinjar; Falkenberg, Torkel; Lewith, George; Jonas, Wayne B. (Journal article; Tidsskriftartikkel; Peer reviewed, 2006-06-24)
      Background: The reasoning behind evaluating medical interventions is that a hierarchy of methods exists which successively produce improved and therefore more rigorous evidence based medicine upon which to make clinical decisions. At the foundation of this hierarchy are case studies, retrospective and prospective case series, followed by cohort studies with historical and concomitant non-randomized ...

    • Regression analysis with categorized regression calibrated exposure. Some interesting findings 

      Dalen, Ingvild; Hjartåker, Anette; Buonaccorsi, John P.; Laake, Petter; Thoresen, Magne (Journal article; Tidsskriftartikkel; Peer reviewed, 2006-07-04)
      Background: Regression calibration as a method for handling measurement error is becoming increasingly well-known and used in epidemiologic research. However, the standard version of the method is not appropriate for exposure analyzed on a categorical (e.g. quintile) scale, an approach commonly used in epidemiologic studies. A tempting solution could then be to use the predicted continuous ...

    • Plasma levels of leptin and mammographic density among postmenopausal women. A cross-sectional study 

      Stuedal, Anne; Bremnes, Yngve; Gram, Inger Torhild; Ursin, Giske; Veierød, Marit B.; Reseland, Janne E.; Drevon, Christian A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2006-09-29)
      Introduction Obesity has been linked to increased risk of breast cancer in postmenopausal women. Increased peripheral production of estrogens has been regarded as the main cause for this association, but other features of increased body fat mass may also play a part. Leptin is a protein produced mainly by adipose tissue and may represent a growth factor in cancer. We examined the association ...

    • A comprehensive analysis of the androgen receptor gene and risk of breast cancer. Results from the National Cancer Institute Breast and Prostate Cancer Cohort Consortium (BPC3) 

      Lund, Eiliv; Cox, David G.; Blanché, Hélène; Pearce, Celeste L.; Calle, Eugenia E.; Colditz, Graham A.; Pike, Malcolm C.; Albanes, Demetrius; Allen, Naomi E.; Amiano, Pilar; Berglund, Göran; Boeing, Heiner; Buring, Julie; Burtt, Noel; Canzian, Federico; Chanock, Stephen; Flavel-Chapelon, Françoise; Feigelson, Heather Spencer; Freedman, Matthew; Haiman, Christopher A.; Hankinson, Susan E.; Henderson, Brian E.; Hoover, Robert; Hunter, David J.; Kaaks, Rudolf; Kolonel, Laurence; Kraft, Peter; LeMarchand, Loic; Palli, Domenico; Peeters, Petra H.M.; Riboli, Elio; Stram, Daniel O.; Thun, Michael; Tjönneland, Anne; Trichopoulos, Dimitrios; Yeager, Meredith (Journal article; Tidsskriftartikkel; Peer reviewed, 2006-09-20)
      Introduction Androgens have been hypothesised to influence risk of breast cancer through several possible mechanisms, including their conversion to estradiol or their binding to the oestrogen receptor and/or androgen receptor (AR) in the breast. Here, we report on the results of a large and comprehensive study of the association between genetic variation in the AR gene and risk of breast cancer ...

    • Influenza pandemic. Perception of risk and individual precautions in a general population. Cross sectional study 

      Kristiansen, Ivar S.; Halvorsen, Peder A.; Gyrd-Hansen, Dorte (Journal article; Tidsskriftartikkel; Peer reviewed, 2007-04-02)
      Background An influenza pandemic may have considerable impact on health and societal functioning. The aim of this study was to explore people's reflections on the consequences of a pandemic. Methods Cross-sectional web-based survey of 1,168 Norwegians aged 16–82 years. The main outcome measures were answers to questions about a potential pandemic ("serious influenza epidemic"): statements about ...

    • Chinese red yeast rice (Monascus purpureus) for primary hyperlipidemia. A meta-analysis of randomized controlled trials 

      Grimsgaard, Sameline; Zhang, Jing; Yi, Shi; Alræk, Terje; Fønnebø, Vinjar; Liu, Jianping (Journal article; Tidsskriftartikkel; Peer reviewed, 2006-11-23)
      Extracts of Chinese red yeast rice (RYR, a traditional dietary seasoning of Monascus purpureus) contains several active ingredients including lovastatin, and several trials of its possible lipid-lowering effects have been conducted. This meta-analysis assesses the effectiveness and safety of RYR preparations on lipid modification in primary hyperlipidemia. We included randomized controlled trials ...

    • Opplevde sammenhenger mellom amalgam og helse i den norske befolkning 

      Norheim, Arne Johan; Ramstad, Susanne (Research report; Forskningsrapport, 2006-11-13)
      Sosial og helsedirektoratet arbeider med retningslinjer for pasientbehandling ved mistanke om helseskade fra amalgamfyllinger. Som bakgrunn for dette arbeid fikk Nasjonalt Forskningssenter innen Komplementær og Alternativ Medisin (NAFKAM) ved Universitetet i Tromsø i oppdrag å beskrive hvordan befolkningen opplever sammenhengen mellom amalgam og helse. Kvantitative og kvalitative metoder har vært ...

    • ”Lifestyle blues” . Om relasjoner mellom glykosylert hemoglobin og kroppsfett samt utvalgte blodlipider hos kvinner og menn i en generell befolkning – Tromsø IV 

      Holm, Kåre Olav (Master thesis; Mastergradsoppgave, 2003-12-01)
      Glykosylert hemoglobin er et stabilt mål for gjennomsnittlig sukkermengde i blodet de siste 6-12 ukene. Høye serum­glukoseverdier er et (kardinal-) symptom på diabetes (diagnostisk kriterium). Manglende glukosekontroll (”impaired glucose tolerance”, IGT) forbindes også med (kardio)vaskulære sjukdoms(risiko)tilstander. HbA1c-test er derfor ett viktig verktøy for å måle en persons (hyper)glykemiske ...
