    • B Vitamins and Hip Fracture: Secondary Analyses and Extended Follow-Up of Two Large Randomized Controlled Trials 

      Garcia Lopez, Maria; Bønaa, Kaare; Ebbing, Marta; Eriksen, Erik Fink; Gjesdal, Clara Gram; Nygård, Ottar; Tell, Grethe S.; Ueland, Per Magne; Meyer, Haakon E (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-28)
      Elevated plasma homocysteine levels are associated with increased risk of fractures in observational studies. However, it is unsettled whether homocysteine-lowering treatment affects fracture risk. The aim of this study was to investigate the effect of an intervention with B vitamins on the risk of hip fracture in a secondary analysis of combined data from two large randomized controlled trials ...

      The etiology of renal cell carcinoma (RCC) is only partially understood, but a metabolic component appears likely. We investigated biomarkers of one-carbon metabolism and RCC onset and survival. Methods The European Prospective Investigation into Cancer and Nutrition (EPIC) recruited 385747 participants with blood samples between 1992 and 2000, and this analysis included 556 RCC case-control pairs. ...

      Experimental and epidemiological data suggest that vitamin D play a role in pathogenesis and progression of cancer, but prospective data on head and neck cancer (HNC) and oesophagus cancer are limited. The European Prospective Investigation into Cancer and Nutrition (EPIC) study recruited 385,747 participants with blood samples between 1992 and 2000. This analysis includes 497 case-control pairs ...

    • Encephalitis and aseptic meningitis: short-term and long-term outcome, quality of life and neuropsychological functioning 

      Paulsen, Else Quist; Ormaasen, Vidar; Kran, Anne-Marte Bakken; Dunlop, Oona Borghild; Ueland, Per Magne; Ueland, Thor; Eikeland, Randi; Aukrust, Pål; Nordenmark, Tonje Haug (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-06)
      For those surviving encephalitis, the influence on daily life of patients and their relatives may be substantial. In contrast, the prognosis after aseptic meningitis (ASM) is considered good. In this prospective study in patients with encephalitis (n = 20) and ASM (n = 46), we show that both groups experienced reduced Health Related Quality of Life (HRQoL) at two months after discharge, and that ...

    • Plasma concentrations and dietary intakes of choline and betaine in association with atrial fibrillation risk: Results from 3 prospective cohorts with different health profiles 

      Zuo, Hui; Svingen, Gard Frodahl Tveitevåg; Tell, Grethe S.; Ueland, Per Magne; Vollset, Stein Emil; Pedersen, Eva Ringdal; Ulvik, Arve; Meyer, Klaus; Nordrehaug, Jan Erik; Nilsen, Dennis W.T.; Bønaa, Kaare; Nygård, Ottar (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-12)
      <p><i>Background - </i>Although choline metabolism has been associated with atherosclerotic heart disease, less research attention has been paid to the associations of choline and its oxidative metabolite betaine with cardiac arrhythmias. <p><i>Methods and Results - </i>We evaluated associations of plasma concentrations and dietary intakes of choline and betaine with long-term atrial fibrillation ...
