Reliability of 24-h measurement of physical activity, sleep, and sedentary time in adult patients with asthma using a triaxial accelerometer.

Objective: Physical activity (PA), sleep, and sedentary time (SST) are important outcomes to monitor and to improve as part of patients' asthma management. This study aimed to assess the number of measurement days needed to reliably measure PA and SST. Secondly, the influence of external factors on the reliability of measuring PA and SST was studied.

Impact of Treatable Traits on Asthma Control and Quality of Life.

Background: Many adult patients with asthma have uncontrolled disease and impaired quality of life, despite current asthma-specific drug therapies.

Objective: This study aimed to investigate the prevalence of 9 traits in patients with asthma, their associations with disease control and quality of life, and referral rates to nonmedical health care professionals.

Methods: Retrospectively, data from patients with asthma were collected in 2 Dutch hospitals (Amphia Breda and RadboudUMC Nijmegen).

Differences in Pulmonary and Extra-Pulmonary Traits between Women and Men with Chronic Obstructive Pulmonary Disease.

Background: Evidence suggests sex-related differences in chronic obstructive pulmonary disease (COPD). Whether these differences are reflected in the prevalence of treatable traits remains unknown. Methods: Two samples of patients referred to secondary (n = 530) or tertiary care (n = 2012) were analyzed.

"Can Do, Do Do" Quadrants and 6-Year All-Cause Mortality in Patients With COPD.

Background: Physical capacity (PC; "can do") and physical activity (PA; "do do") are prognostic indicators in COPD and can be used to subdivide patients with COPD into four exclusive subgroups (the so-called "can do, do do" quadrants). This concept may be useful to understand better the impact of PC and PA on all-cause mortality in patients with COPD.

Research Question: What is the 6-year all-cause mortality risk of the "can do, do do" quadrants of patients with COPD?

Study Design And Methods: This retrospective study used data from patients with COPD who underwent a comprehensive assessment at their first-ever outpatient consultation.
