New Spirometry Indices for Detecting Mild Airflow Obstruction. [PDF]

, 2018
The diagnosis of chronic obstructive pulmonary disease (COPD) relies on demonstration of airflow obstruction. Traditional spirometric indices miss a number of subjects with respiratory symptoms or structural lung disease on imaging.

Changes in Forced Expiratory Volume in 1 Second over Time in COPD [PDF]

New England Journal of Medicine, 2011
A key feature of chronic obstructive pulmonary disease (COPD) is an accelerated rate of decline in forced expiratory volume in 1 second (FEV(1)), but data on the variability and determinants of this change in patients who have established disease are scarce.We analyzed the changes in FEV(1) after administration of a bronchodilator over a 3-year period ...

Airways oxidative stress, lung function and cognitive impairment in aging. [PDF]

, 2010
BACKGROUND: An altered balance of oxidants/antioxidants is one of the pathological mechanisms of many age-dependent disorders. We aimed to investigate the age-related airways oxidative stress, using non invasive, safe and repeatable techniques; to ...

Relationships between estimated autozygosity and complex traits in the UK Biobank [PDF]

, 2018
Inbreeding increases the risk of certain Mendelian disorders in humans but may also reduce fitness through its effects on complex traits and diseases. Such inbreeding depression is thought to occur due to increased homozygosity at causal variants that ...
