The Association of COPD Patients’ and Caregivers’ KAP with Inhaler Adherence: An Actor-Partner Interdependence Model Analysis
Purpose: Chronic obstructive pulmonary disease (COPD) is a leading cause of global mortality, yet inhaler adherence remains suboptimal. Caregivers may play a critical role in patients’ medication behavior, but the underlying mechanisms a...

Erdosteine, but Not N-Acetylcysteine, is Associated with Improved Homogeneity of Alveolar Ventilation in Patients with Mild-to-Moderate COPD Treated with LABA/LAMA
Purpose: Ventilation inhomogeneity and impaired alveolar ventilation (VA) are important abnormalities in chronic obstructive pulmonary disease (COPD) and may persist despite optimized bronchodilator therapy. Volumetric capnography (VCap)...

Acute Effects of Inspiratory Muscle Training with Different Loads on Peripheral Muscle Oxygenation Kinetics and Autonomic Response in Patients with COPD: A Protocol for a Randomized Crossover Study
Background: Chronic obstructive pulmonary disease (COPD) leads to inspiratory muscle weakness, which may contribute to an altered cardiovascular response during the respiratory cycle. In this context, inspiratory muscle training (IMT) em...
