    • 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 ...

      <p><i>Background</i>: High adherence to the Healthy Nordic Food Index has been associated with better health outcomes, but the results have not been consistent. The association between high adherence and higher intake of energy and healthy and less healthy foods has been persistent across countries, highlighting the need to examine potential confounding by energy intake.</p> <p><i>Objective</i>: ...
    • Adherence to the healthy Nordic food index, dietary composition, and lifestyle among Swedish women 

      Roswall, Nina; Eriksson, Ulf; Sandin, Sven; Löf, Marie; Olsen, Anja; Skeie, Guri; Adami, Hans Olov; Weiderpass, Elisabete (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-03-11)
      <p>Background: Studies examining diet scores in relation to health outcomes are gaining ground. Thus, control for dietary factors not part of the score, and lifestyle associated with adherence, is required to allow for a causal interpretation of studies on diet scores and health outcomes. <p>Objective: The study objective is to describe and investigate dietary composition, micronutrient density, ...

      Stub, Trine; Musial, Frauke; Kristoffersen, Agnete Egilsdatter; Alræk, Terje; Liu, Jianping (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-03-26)
      Objectives:<br>Homeopathy is a popular treatment modality among patient, however there is sparse research about adverse effects of homeopathy. A concept unique for homeopathy, is homeopathic aggravation that is understood as a transient worsening of the patients’ symptoms before an expected improvement occurs. From a risk perspective it is vital that a distinction between homeopathic aggravations ...

Participants were followed for occurrence of breast cancer and death until December 2009. Poisson regression ...
    • The ambiguity of physical activity, exercise and atrial fibrillation 

      Morseth, Bente; Løchen, Maja-Lisa; Ariansen, Inger Kristine Holtermann; Myrstad, Marius; Thelle, Dag Steinar (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-07)
      Although commonly associated with cardiovascular disease or other medical conditions, atrial fibrillation may also occur in individuals without any known underlying conditions. This manifestation of atrial fibrillation has been linked to extensive and long-term exercise, as prolonged endurance exercise has shown to increase prevalence and risk of atrial fibrillation. In contrast, more modest physical ...
    • Analgesic use in a Norwegian general population: Change over time and high-risk use - The Tromsø Study 

      Samuelsen, Per-Jostein; Slørdal, Lars; Mathisen, Ulla Dorte; Eggen, Anne Elise (Journal article; Tidsskriftartikkel, 2015-06-06)
      Background: Increased use of analgesics in the population is a cause for concern in terms of drug safety. There is a paucity of population-based studies monitoring the change in use over time of both non-prescription (OTC) analgesics and prescription (Rx) analgesics. Although much is known about the risks associated with analgesic use, we are lacking knowledge on high-risk use at a population level. ...

(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-04-05)
      Invasive epithelial ovarian cancer (EOC) is the most lethal gynecologic malignancy. The etiology of EOC remains elusive; however, experimental and epidemiologic data suggest a role for hormone-related exposures in ovarian carcinogenesis and risk factor differences by histologic phenotypes and developmental pathways. Research on pre-diagnosis androgen concentrations and EOC risk has yielded inconclusive ...
    • The Apolipoprotein B/Apolipoprotein A-I Ratio as a Potential Marker of Plasma Atherogenicity 

      Kaneva, Anastasiya M.; Potolitsyna, Natalya N.; Bojko, Evgeny R.; Odland, Jon Øyvind (Journal article; Tidsskriftartikkel; Peer reviewed, 2015)
      Background. The apolipoprotein (apo) B/apoA-I ratio represents the balance between apoB-rich atherogenic particles and apoAI-rich antiatherogenic particles, and this ratio is considered to be a marker of cardiovascular risk. Although many studies have demonstrated the importance of the apoB/apoA-I ratio in predicting the presence or absence of cardiovascular disease, less is known about apoB/apoA-I ...
