    • Circulating trimethylamine N-oxide levels do not predict 10-year survival in patients with or without coronary heart disease 

      Bjørnestad, Espen Øglænd; Dhar, Indu; Svingen, Gard Frodahl Tveitevåg; Pedersen, Eva Kristine Ringdal; Ørn, Stein; Svenningsson, Mads Malm; Tell, Grethe Seppola; Ueland, Per Magne; Sulo, Gerhard; Laaksonen, Reijo; Nygård, Ottar Kjell (Journal article; Peer reviewed, 2022)
      Background Trimethylamine N-oxide (TMAO) is an amine oxide generated by gut microbial metabolism. TMAO may contribute to atherothrombosis and systemic inflammation. However, the prognostic value of circulating TMAO for ...

    • Implementation of nutritional guidelines in a university hospital monitored by repeated point prevalence surveys 

      Tangvik, Randi Julie; Guttormsen, Anne Berit; Tell, Grethe Seppola; Ranhoff, Anette Hylen (Peer reviewed; Journal article, 2012)
      Background/Objectives: Malnutrition is present in 20–50% of hospitalized patients, and nutritional care is a challenge. The aim was to evaluate whether the implementation of a nutritional strategy would influence nutritional ...

    • Nutritional risk profile in a university hospital population 

      Tangvik, Randi Julie; Tell, Grethe Seppola; Guttormsen, Anne Berit; Eisman, John A.; Henriksen, Andreas; Nilsen, Roy Miodini; Ranhoff, Anette Hylen (Peer reviewed; Journal article, 2015)
      Background & aims: The prevalence of nutritional risk varies according to several factors. We aimed to determine the nutritional risk profile in a large Norwegian hospital population, specifically by age, disease category ...

    • The nutritional strategy: four questions predict morbidity, mortality and health care costs 

      Tangvik, Randi Julie; Tell, Grethe Seppola; Eisman, John A.; Guttormsen, Anne Berit; Henriksen, Andreas; Nilsen, Roy Miodini; Øyen, Jannike; Ranhoff, Anette Hylen (Peer reviewed; Journal article, 2014-08)
