    • Direct and indirect risk associated with the use of dietary supplements among persons with dementia in a Norwegian memory clinic 

      Risvoll, Hilde; Giverhaug, Trude; Halvorsen, Kjell H.; Waaseth, Marit; Musial, Frauke (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-05-12)
      Background: The use of dietary supplements (DS) is common among persons with dementia. Direct risks associated with DS use include adverse events and DS-drug interactions. A direct risk is a risk caused by the treatment itself. Indirect risks are related to the treatment setting, such as the conditions of use, and not to the treatment itself. Because dementia symptoms may reduce a person’s ability ...
    • Hormone replacement therapy use and plasma levels of sex hormones in the Norwegian Women and Cancer Postgenome Cohort : a cross-sectional analysis 

      Waaseth, Marit; Bakken, Kjersti; Dumeaux, Vanessa; Olsen, Karina Standahl; Rylander, Charlotta; Figenschaug, Yngve; Lund, Eiliv (Journal article; Tidsskriftartikkel; Peer reviewed, 2008-02-14)
      Background: Hormone replacement therapy use (HRT) is associated with increased breast cancer risk. Our primary objective was to explore hormone levels in plasma according to HRT use, body mass index (BMI) and menopausal status. A secondary objective was to validate self-reported questionnaire information on menstruation and HRT use in the Norwegian Women and Cancer postgenome cohort (NOWAC). Methods: ...
    • Hormone therapy use, sex hormone concentrations and gene expression : The Norwegian Women and Cancer study (NOWAC) 

      Waaseth, Marit (Doctoral thesis; Doktorgradsavhandling, 2010-08-27)
      I følge salgsstatistikken økte forbruket av hormontilskudd kraftig i Norge på 1990-tallet, men avtok fra 2002. Både hormontilskudd og kroppens egenproduserte kjønnshormoner er relatert til kreft hos kvinner, bl.a. brystkreft. Kreft karakteriseres ved ukontrollert celledeling som utvikles gradvis gjennom endringer i genmaterialet. Teknologisk utvikling gjør det mulig å utforske sammenhenger mellom ...
    • Knowledge of antibiotics and antibiotic resistance among Norwegian pharmacy customers – a cross-sectional study 

      Waaseth, Marit; Adan, Abdifatah; Røen, Ingrid L.; Eriksen, Karoline; Stanojevic, Tijana; Halvorsen, Kjell H.; Garcia, Beate Hennie; Holst, Lone; Ulshagen, Karen Marie; Blix, Hege Salvesen; Ariansen, Hilde Louise; Nordeng, Hedvig Marie Egeland (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-15)
      <p><i>Background</i>: Antibiotic resistance is a global health threat. Public knowledge is considered a prerequisite for appropriate use of antibiotics and limited spread of antibiotic resistance. Our aim was to examine the level of knowledge of antibiotics and antibiotic resistance among Norwegian pharmacy customers, and to assess to which degree beliefs, attitudes and sociodemographic factors are ...
    • Medication Errors and Safety Culture in a Norwegian Hospital 

      Waaseth, Marit; Ademi, Adelina; Fredheim, Mette; Antonsen, Margaret Aarag; Brox, Nina M Bjæring; Lehnbom, Elin (Journal article; Tidsskriftartikkel; Peer reviewed, 2019)
      Medication errors are associated with adverse health outcomes and may prolong hospital stays and increase societal costs. Safety initiatives to reduce adverse health outcomes should be based on reliable information of current shortcomings. The aim of this study was to identify barriers to medication error reporting in a hospital and to describe heath personnel’s views of the safety culture. Seven ...
    • Naturlegemidler. Omsetning og lovgivning 

      Waaseth, Marit (Master thesis; Mastergradsoppgave, 2004-12-02)
      Naturlegemidler – omsetning og lovgivning Bakgrunn Bruk av naturmidler øker i vestlige land inkludert Norge. Urtemedisin brukes vanligvis som egenbehandling, men interessen er økende også i etablert helsevesen. Naturlegemiddelordningen ble opprettet i 1994 for å gi et mer oversiktlig naturmiddelmarked. Salgsomfang og bruk av naturlegemidler er ikke kartlagt i særlig grad og lovgivningen omkring ...
    • Overdiagnosis of breast cancer in the Norwegian Breast Cancer Screening Program estimated by the Norwegian Women and Cancer cohort study 

      Lund, Eiliv; Mode, Nicolle; Waaseth, Marit; Thalabard, Jean-Christophe (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Background: There is increasing ambiguity towards national mammographic screening programs due to varying publicized estimates of overdiagnosis, i.e., breast cancer that would not have been diagnosed in the women’s lifetime outside screening. This analysis compares the cumulative incidence of breast cancer in screened and unscreened women in Norway from the start of the fully implemented Norwegian ...
    • Plasma Fatty Acid Ratios Affect Blood Gene Expression Profiles - A Cross-Sectional Study of the Norwegian Women and Cancer Post-Genome Cohort 

      Olsen, Karina Standahl; Fenton, Christopher Graham; Frøyland, Livar; Waaseth, Marit; Paulssen, Ruth H; Lund, Eiliv (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      High blood concentrations of n-6 fatty acids (FAs) relative to n-3 FAs may lead to a “physiological switch” towards permanent low-grade inflammation, potentially influencing the onset of cardiovascular and inflammatory diseases, as well as cancer. To explore the potential effects of FA ratios prior to disease onset, we measured blood gene expression profiles and plasma FA ratios (linoleic ...
    • Progestin-only and combined oral contraceptives and receptor-defined premenopausal breast cancer risk: The Norwegian Women and Cancer Study 

      Busund, Marit Katinka; Stensland-Bugge, Nora; Braaten, Tonje; Waaseth, Marit; Rylander, Charlotta; Lund, Eiliv (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-19)
      Receptor-defined subtypes of breast cancer represent distinct cancer types and have differences in risk factors. Whether the two main hormonal forms of oral contraceptives (OCs); i.e. progestin-only (POC) and combined oral contraceptives (COC), are differentially associated with these subtypes are not well known. The aim of our study was to assess the effect of POC and COC use on hormone receptor-defined ...

      Waaseth, Marit; Olsen, Karina Standahl; Rylander, Charlotta; Lund, Eiliv; Dumeaux, Vanessa (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
