• The airway microbiota of stable COPD : Association with exacerbation frequency and the risks associated with bronchoscopic data collection 

      Leiten, Elise Orvedal (Doctoral thesis, 2022-03-25)
      Background: Acute exacerbations of COPD are an important cause of mortality and morbidity in patients with COPD. It is incompletely understood why some COPD patients experience frequent exacerbations, while others rarely ...

      Martinsen, Einar Marius Hjellestad; Eagan, Tomas Mikal; Leiten, Elise Orvedal; Nordeide, Eli; Bakke, Per S.; Lehmann, Sverre; Nielsen, Rune (Peer reviewed; Journal article, 2019-05-02)
      Background Bronchoscopy is frequently used to sample the lower airways in lung microbiome studies. Despite being a safe procedure, it is associated with discomfort that may result in reservations regarding participation ...
    • Participation in research bronchoscopy: a literature review 

      Martinsen, Einar Marius Hjellestad; Leiten, Elise Orvedal; Bakke, Per S.; Eagan, Tomas Mikal; Grønseth, Rune (Peer reviewed; Journal article, 2016-02-03)
      Bronchoscopy is the preferred method for collecting biological samples from the lower airways of subjects in clinical research. However, ensuring participation in clinical research can be challenging when the research ...
    • Protected sampling is preferable in bronchoscopic studies of the airway microbiome 

      Grønseth, Rune; Drengenes, Christine; Wiker, Harald G; Tangedal, Solveig; Xue, Yaxin; Husebø, Gunnar; Svanes, Øistein; Lehmann, Sverre; Aardal, Marit Elisabeth; Hoang, Tuyen; Kalananthan, Tharmini; Martinsen, Einar Marius Hjellestad; Leiten, Elise Orvedal; Aanerud, Marianne; Nordeide, Eli; Haaland, Ingvild; Jonassen, Inge; Bakke, Per S.; Eagan, Tomas Mikal (Journal article; Peer reviewed, 2017)
      The aim was to evaluate susceptibility of oropharyngeal contamination with various bronchoscopic sampling techniques. 67 patients with obstructive lung disease and 58 control subjects underwent bronchoscopy with ...
