• Can spirometric norms be set using pre- or post- bronchodilator test results in older people? 

      Kato, Bernet; Gulsvik, Amund; Vollmer, William; Janson, Christer; Studnika, Michael; Buist, Sonia; Burney, Peter (Peer reviewed; Journal article, 2012-11-16)
      Background: Chronic Obstructive Pulmonary Disease (COPD) is defined by post-bronchodilator spirometry. Data on “normal values” come predominantly from pre-bronchodilator spirometry. The effects of this on diagnosis are ...
    • Comparing microbiota profiles in induced and spontaneous sputum samples in COPD patients 

      Tangedal, Solveig; Aanerud, Marianne; Grønseth, Rune; Drengenes, Christine; Wiker, Harald G; Bakke, Per S.; Eagan, Tomas Mikal (Peer reviewed; Journal article, 2017-08-29)
      Background: Induced and spontaneous sputum are used to evaluate the airways microbiota. Whether the sputum types can be used interchangeably in microbiota research is unknown. Our aim was to compare microbiota in induced ...
    • DNAH5 is associated with total lung capacity in chronic obstructive pulmonary disease 

      Lee, Jin H.; McDonald, Merry-Lynn N.; Cho, Michael H.; Wan, Emily S.; Castaldi, Peter J.; Hunninghake, Gary M.; Marchetti, Nathaniel; Lynch, David A.; Crapo, James D.; Lomas, David A.; Coxson, Harvey O.; Bakke, Per; Silverman, Edwin K.; Hersh, Craig P. (Peer reviewed; Journal article, 2014-08-20)
      Background: Chronic obstructive pulmonary disease (COPD) is characterized by expiratory flow limitation, causing air trapping and lung hyperinflation. Hyperinflation leads to reduced exercise tolerance and poor quality of ...
    • Early life environment and snoring in adulthood 

      Franklin, Karl A.; Janson, Christer; Gíslason, Thórarinn; Gulsvik, Amund; Gunnbjörnsdottir, Maria; Lærum, Birger Norderud; Lindberg, Eva; Norrman, Eva; Nyström, Lennarth; Omenaas, Ernst; Torén, Kjell; Svanes, Cecilie (Peer reviewed; Journal article, 2008-08-22)
      Background: To our knowledge, no studies of the possible association of early life environment with snoring in adulthood have been published. We aimed to investigate whether early life environment is associated with snoring ...
    • Genetic susceptibility for chronic bronchitis in chronic obstructive pulmonary disease 

      Lee, Jin H.; Cho, Michael H.; Hersh, Craig P.; McDonald, Merry-Lynn N.; Crapo, James D.; Bakke, Per; Gulsvik, Amund; Comellas, Alejandro P.; Wendt, Christine H.; Lomas, David A.; Kim, Victor; Silverman, Edwin K.; on behalf of the COPDGene and ECLIPSE Investigators (Peer reviewed; Journal article, 2014-09-21)
      Background: Chronic bronchitis (CB) is one of the classic phenotypes of COPD. The aims of our study were to investigate genetic variants associated with COPD subjects with CB relative to smokers with normal spirometry, and ...
    • TNF-α is associated with loss of lean body mass only in already cachectic COPD patients
