Hyperpolarized 129XeMRI Offers Detailed View of Valve Replacement Outcomes
Can the hyperpolarized xenon-129 transfer contrast MRI, which details ventilation and gas exchange, help to characterize successful vs unsuccessful endobronchial valve placements?
New Case-Finding Questionnaire for Undiagnosed Asthma and COPD
Investigators created and validated the Undiagnosed COPD and Asthma Population Questionnaire to overcome limitations of existing case-finding tools.
Endobronchial Ultrasound-Guided TBNA Outcomes in Patients Aged 65 and Above
How do outcomes of endobronchial ultrasound-guided transbronchial fine needle aspiration differ in patients aged 65 or older vs those younger than 65?
Impaired Ventilatory Efficiency, Dyspnea, and Exercise Limitation in COPD
The CanCOLD study assessed linkage between high VE/VCO2, dyspnea, and exercise capacity, as well as the link between high V̇E/V̇CO2 and lung function impairment.
Functional Exercise Capacity in COPD: Are Field Tests Reliable Measures?
In patients with COPD, can functional exercise capacity be reliably measured using field tests such as the incremental shuttle walk test and 6-minute walk test?
