• Exploring protocol bias in airway microbiome studies: one versus two PCR steps and 16S rRNA gene region V3 V4 versus V4 

      Drengenes, Christine; Eagan, Tomas Mikal; Haaland, Ingvild; Wiker, Harald G; Nielsen, Rune (Journal article; Peer reviewed, 2021)
      Background Studies on the airway microbiome have been performed using a wide range of laboratory protocols for high-throughput sequencing of the bacterial 16S ribosomal RNA (16S rRNA) gene. We sought to determine the ...
    • ILD-­specific health-­related quality of life in systemic sclerosis-­associated ILD compared with IPF 

      Durheim, Michael; Hoffmann-Vold, Anna-Maria; Eagan, Tomas Mikal; Hovden, Arnt-Ove; Samersaw-Lund, May Brit; Bjerke, Gisle; Birring, Surinder S.; Jonassen, Trygve Müller; Johansen, Odd Erik; Sjåheim, Tone Bjørg (Journal article; Peer reviewed, 2020)
      Abstract Introduction Idiopathic pulmonary fibrosis (IPF) and systemic sclerosis-associated interstitial lung disease (SSc-ILD) are fibrotic ILDs with divergent disease populations. Little is known about health-related ...
    • Incremental costs of COPD exacerbations in GOLD stage 2+ COPD in ever-smokers of a general population 

      Erdal, Marta; Johannessen, Ane; Bakke, Per S.; Gulsvik, Amund; Eagan, Tomas Mikal; Nielsen, Rune (Journal article; Peer reviewed, 2020-11)
      Objectives To estimate treatment- and productivity-related costs associated with COPD in two different samples, and to analyse the association between the costs and moderate and severe exacerbations. Methods We performed ...
    • 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 ...
