Association Between Long-term Exposure to Ambient Air Pollution and Change in Quantitatively Assessed Emphysema and Lung Function
Meng Wang,Meng Wang,Carrie P. Aaron,Jaime Madrigano,Jaime Madrigano,Eric A. Hoffman,Elsa D. Angelini,Jie Yang,Andrew F. Laine,Thomas Vetterli,Patrick L. Kinney,Paul D. Sampson,Lianne Sheppard,Adam A. Szpiro,Sara D. Adar,Kipruto Kirwa,Benjamin M. Smith,Benjamin M. Smith,David J. Lederer,David J. Lederer,Ana V. Diez-Roux,Sverre Vedal,Joel D. Kaufman,R. Graham Barr,R. Graham Barr +24 more
TL;DR: In this cohort study conducted between 2000 and 2018 in 6 US metropolitan regions, long-term exposure to ambient air pollutants was significantly associated with increasing emphysema assessed quantitatively using CT imaging and lung function.
Journal ArticleDOI
Inhaled and intranasal ciclesonide for the treatment of covid-19 in adult outpatients: CONTAIN phase II randomised controlled trial.
Nicole Ezer,Sara Belga,Nick Daneman,Adrienne K. Chan,Benjamin M. Smith,Shay-Anne Daniels,Kristen Moran,Charlotte Besson,Louisa Y Smyth,Susan J. Bartlett,Andrea Benedetti,James G. Martin,Todd C. Lee,Emily G. McDonald +13 more
TL;DR: In this article, inhaled and intranasal corticosteroids were compared with placebo for the treatment of covid-19 respiratory symptoms in adults with fever, cough, or dyspnoea.
Journal ArticleDOI
Association of Nonobstructive Chronic Bronchitis With Respiratory Health Outcomes in Adults.
Pallavi Balte,Paulo H M Chaves,David Couper,Paul L. Enright,David R. Jacobs,Ravi Kalhan,Richard A. Kronmal,Laura R. Loehr,Stephanie J. London,Anne B. Newman,George T. O'Connor,Joseph E. Schwartz,Benjamin M. Smith,Lewis J. Smith,Wendy B. White,Sachin Yende,Elizabeth C. Oelsner +16 more
TL;DR: The findings suggest that nonobstructive chronic bronchitis is associated with adverse respiratory health outcomes, particularly in ever smokers, and may be a high-risk phenotype suitable for risk stratification and targeted therapies.
Journal ArticleDOI
Pulmonary hyperinflation due to gas trapping and pulmonary artery size: The MESA COPD Study.
Hooman D. Poor,Steven M. Kawut,Chia Ying Liu,Benjamin M. Smith,Eric A. Hoffman,Joao A.C. Lima,Bharath Ambale-Venkatesh,Erin D. Michos,Martin R. Prince,R. Graham Barr +9 more
TL;DR: Increased residual volume was associated with a larger PA in COPD, suggesting that gas trapping may contribute to pulmonary hypertension in COPd.
Journal ArticleDOI
Impact of pulmonary emphysema on exercise capacity and its physiological determinants in chronic obstructive pulmonary disease.
Benjamin M. Smith,Dennis Jensen,Dennis Jensen,Marc Brosseau,Andrea Benedetti,Andrea Benedetti,Harvey O. Coxson,Jean Bourbeau,Jean Bourbeau +8 more
TL;DR: The extent of pulmonary emphysema predicts lower exercise capacity, ventilatory inefficiency, impaired gas-exchange and increased heart rate response to exercise independent of contemporary measures of COPD severity.
