      Breckan, Ragnar K; Paulssen, Eyvind Jakob; Asfeldt, Anne Mette; Kvamme, Jan-Magnus; Straume, Bjørn; Florholmen, Jon (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-05-12)
      Background and aims: Previous research on H. pylori epidemiology has mostly focused on adult populations. We have aimed to study H. pylori prevalence in all age groups including children and adolescents and to identify potential routes of transmission. Methods: Subjects from all age groups (children 0–11 years, adolescents 12–17 years and adults ≥18 years of age), recruited from both an urban ...

    • Body mass index and mortality in elderly men and women: the Tromso and HUNT studies 

      Kvamme, Jan-Magnus; Holmen, Jostein; Wilsgaard, Tom; Florholmen, Jon; Midthjell, Kristian; Jacobsen, Bjarne Koster (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      The impact of body mass index (BMI; kg/m2) and waist circumference (WC) on mortality in elderly individuals is controversial and previous research has largely focused on obesity. With special attention to the lower BMI categories, associations between BMI and both total and cause-specific mortality were explored in 7604 men and 9107 women aged ≥65 years who participated in the Tromsø Study (1994–1995) ...

    • Body mass index and risk of malnutrition in community-living elderly men and women: relationships with morbidity, mortality and health- related quality of life. The Tromsø and HUNT studies 

      Kvamme, Jan-Magnus (Doctoral thesis; Doktorgradsavhandling, 2011-06-09)
      The elderly population is rapidly growing, and elderly individuals are more vulnerable to nutritional problems than other adults. A number of studies have found evidence for adverse health outcomes in elderly patients at risk of malnutrition. However, much of the previous research has been performed in hospital populations or in groups of elderly patients with specific diagnoses. More population-based ...

      <i>Background</i> - There are no accurate markers that can predict clinical outcome in ulcerative colitis at time of diagnosis. The aim of this study was to explore a comprehensive data set to identify and validate predictors of clinical outcome in the first year following diagnosis.<p> <p><i>Methods</i> - Treatment naive-patients with ulcerative colitis were included at time of initial diagnosis ...

    • The effect of train-the-colonoscopy-trainer course on colonoscopy quality indicators 

      Hoff, Geir; Botteri, Edoardo; Huppertz-Hauss, Gert; Kvamme, Jan-Magnus; Holme, Øyvind; Aabakken, Lars; Dahler, Stein; Medhus, Asle Wilhelm; Blomgren, Ingrid; Sandvei, Per; Darre-Næss, Ole; Kjellevold, Øystein; Seip, Birgitte Karen Berggreen (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-23)
      Background - Systematic training in colonoscopy is highly recommended; however, we have limited knowledge of the effects of “training-the-colonoscopy-trainer” (TCT) courses. Using a national quality register on colonoscopy performance, we aimed to evaluate the effects of TCT participation on defined quality indicators.<p> <p>Methods - This observational study compared quality indicators (pain, ...

    • Population-based screening for celiac disease reveals that the majority of patients are undiagnosed and improve on a gluten-free diet 

      Kvamme, Jan-Magnus; Sørbye, Sveinung; Florholmen, Jon; Halstensen, Trond S. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-25)
      The impact of a gluten-free diet (GFD) on screen-detected celiac disease (CD) is currently ambiguous. We aimed to identify the population-based prevalence of undiagnosed adult CD and examine the impact of a GFD on screen-detected CD. In total, 12,981 adults participated in a population-based health study in Tromsø, Norway. Participants with increased levels of anti-tissue transglutaminase-2 IgA ...

    • Risk of malnutrition and health-related quality of life in community-living elderly men and women : the Tromsø study. 

      Kvamme, Jan-Magnus; Olsen, Jan Abel; Florholmen, Jon; Jacobsen, Bjarne Koster (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Purpose To explore the association between risk of malnutrition as well as current body mass index (BMI) and health-related quality of life (HRQoL) in elderly men and women from the general population. Methods In a cross-sectional population survey including 1,632 men and 1,654 women aged 65 to 87 years from the municipality of Tromsø, Norway, we assessed HRQoL by using the EuroQol (EQ-5D) ...

    • Risk of malnutrition and zinc deficiency in community-living elderly men and women: the Tromsø Study 

      Kvamme, Jan-Magnus; Grønli, Ole Kristian; Jacobsen, Bjarne Koster; Florholmen, Jon (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-11-06)

    • Risk of malnutrition is associated with mental health symptoms in community living elderly men and women: The Tromsø Study 

      Kvamme, Jan-Magnus; Grønli, Ole Kristian; Florholmen, Jon; Jacobsen, Bjarne Koster (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Little research has been done on the relationship between malnutrition and mental health in community living elderly individuals. In the present study, we aimed to assess the associations between mental health (particularly anxiety and depression) and both the risk of malnutrition and body mass index (BMI, kg/m2) in a large sample of elderly men and women from Tromsø, Norway. In a cross-sectional ...

    • A Shigella sonnei outbreak traced to imported basil - The importance of good typing tools and produce traceability systems, Norway, 2011 

      Guzman Herrador, Bernardo; Nilsen, Einar; Cudjoe, Kofitsyo S; Jensvoll, Laila; Kvamme, Jan-Magnus; Lindegård Aanstad, Anja; Lindstedt, Bjørn Arne; Nygård, Karin Maria; Severinsen, G; Werner-Johansen, Ø; Wester, Astrid Louise; Wiklund, Marit; Vold, Line (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      On 9 October 2011, the University Hospital of North Norway alerted the Norwegian Institute of Public Health (NIPH) about an increase in Shigella sonnei infections in Tromsø. The isolates had an identical ‘multilocus variable-number tandem repeat analysis’ (MLVA) profile. Most cases had consumed food provided by delicatessen X. On 14 October, new S. sonnei cases with the same MLVA-profile were reported ...

    • Vitamin D deficiency is common in psychogeriatric patients, independent of diagnosis 

      Grønli, Ole Kristian; Kvamme, Jan-Magnus; Jorde, Rolf; Wynn, Rolf (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-05-08)
      Background:Previous studies have found an association between psychiatric disorders and vitamin D deficiency, but most studies have focused on depression. This study aimed to establish the prevalence of vitamin D deficiency in elderly patients with a wider range of psychiatric diagnoses. Method: The study included elderly patients (>64 years) referred to a psychiatric hospital in Northern Norway ...

    • Zinc deficiency is common in several psychiatric disorders 

      Grønli, Ole Kristian; Kvamme, Jan-Magnus; Friborg, Oddgeir; Wynn, Rolf (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Background: Mounting evidence suggests a link between low zinc levels and depression. There is, however, little knowledge about zinc levels in older persons with other psychiatric diagnoses. Therefore, we explore the zinc status of elderly patients suffering from a wide range of psychiatric disorders. Methods: Clinical data and blood samples for zinc analyzes were collected from 100 psychogeriatric ...
