    • Motivation and response rates in bronchoscopy studies 

      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 ...
    • The mycobiome in COPD: Descriptive and longitudinal analysis, and participation in research bronchoscopy studies 

      Martinsen, Einar Marius Hjellestad (Doctoral thesis, 2021-06-25)
      Background: Chronic obstructive pulmonary disease (COPD) is a high-prevalent lung disease with high mortality rates. The COPD pathogenesis is only partly understood, and we do not know why some risk factor exposed subjects ...
    • 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 ...
