Elevated Diaphragmatic Tonic Activity in PICU Patients: Age-Specific Definitions, Prevalence, and Associations.

Objectives: Tonic diaphragmatic activity (tonic Edi, i.e., sustained diaphragm activation throughout expiration) reflects diaphragmatic effort to defend end-expiratory lung volumes.

Patients' perspective of barriers and facilitators to taking long-term controller medication for asthma: a novel taxonomy.

Background: Although asthma morbidity can be prevented through long-term controller medication, most patients with persistent asthma do not take their daily inhaled corticosteroid. The objective of this study was to gather patients' insights into barriers and facilitators to taking long-term daily inhaled corticosteroids as basis for future knowledge translation interventions.

Methods: We conducted a collective qualitative case study.

Facilitators and solutions for practicing optimal guided asthma self-management: the physician perspective.

Objective: To identify key solutions that facilitate the prescription of long-term asthma controller and provision of written self-management plans by physicians.

Methods: One hour individualized semistructured interviews were conducted with physicians. Interviews were transcribed verbatim and analyzed independently by two trained qualitative researchers.
