Prediction of Total Lung Capacity and Residual Volume Eligibilities for Endobronchial Valve Treatment Using Measurements by the Helium Dilution Technique, CT‐Based Lung Volume Analysis, and Spirometry

open access: yesRespirology, EarlyView.
When body plethysmography is not feasible, helium dilution and CT volumetry, alone or combined with spirometry, may provide practical alternatives to help identify patients likely or unlikely to meet plethysmography‐defined eligibility criteria for endobronchial valve treatment.

Expiratory flow limitation detected by forced oscillation and negative expiratory pressure

open access: yes, 2007
The within-breath change in reactance (Delta(X) over bar rs) measured by forced oscillation technique (FOT) at 5 Hz reliably detects expiratory flow limitation in chronic obstructive pulmonary disease (COPD).

Asthma: From Phenotypes to Endotypes—Beyond Type 2 Inflammation

open access: yesRespirology, EarlyView.
ABSTRACT Asthma is a heterogeneous syndrome featuring variable pathophysiology, clinical presentation and treatment response. This review examines a comprehensive endotype‐phenotype framework for asthma assessment with an emphasis on characteristics beyond T2 inflammatory status alone.

A Test of the Coase Conjecture Using Prices of Electronic Books

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT The Coase Conjecture predicts that a durable‐goods monopolist without commitment will rapidly cut price toward marginal cost. We test this prediction in the electronic‐book market using release‐day prices. To proxy for marginal cost, we use competitive prices of public‐domain electronic books on the same platforms.
