6-Min walk-test data in severe obstructive-sleep-apnea-hypopnea-syndrome (OSAHS) under continuous-positive-airway-pressure (CPAP) treatment.

Introduction: Few studies have evaluated the functional capacity of severe OSAHS.

Aims: To assess their functional capacity, identify their 6-min walking-distance (6MWD) influencing factors and compare their data with those of two control-groups.

Methods: Sixty (42 males) clinically consecutive stable patients with severe OSAHS under CPAP were included.

Delays for diagnosis and treatment of lung cancers: a systematic review.

Background And Aims: The impact of diagnosis and treatment delays for non-small cell lung cancer management is poorly understood, even if the literature on the subject is currently increasing in importance. We have few indicators that can serve as reference for quality assurance actions. The objective of this review was to review the literature on the subject.
