Multicenter Study Observational StudyIdentification and distribution of COPD phenotypes in clinical practice according to Spanish COPD Guidelines: the FENEPOC study.
The Spanish Guidelines for COPD (GesEPOC) describe four clinical phenotypes: non-exacerbator (NE), asthma-COPD overlap syndrome (ACO), frequent exacerbator with emphysema (EE), and exacerbator with chronic bronchitis (ECB). The objective of this study was to determine the frequency of COPD phenotypes, their clinical characteristics, and the availability of diagnostic tools to classify COPD phenotypes in clinical practice. ⋯ In Spanish clinical practice, almost half of the patients with COPD presented with NE phenotype. The prevalence of ACO according to the Spanish consensus definition was very low. In general, physicians indicated that they had the necessary tools for diagnosing COPD phenotypes.

Multicenter Study Comparative StudyTreatment trends in patients with asthma-COPD overlap syndrome in a COPD cohort: findings from a real-world survey.
Asthma and chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) is an increasingly recognized phenotype. Few randomized clinical trials have been conducted in patients with ACOS; therefore, scientific evidence concerning ACOS is scarce and a therapeutic approach remains unclear. The aim of this study was to evaluate current treatment trends for patients with ACOS, identified as those with a dual definition of asthma and COPD, in a real-world COPD cohort. ⋯ The majority of patients with ACOS, as defined in this research, were prescribed similar treatment to those with COPD. There is a need, however, for better treatment for patients with ACOS, as indicated by symptoms and exacerbation levels. A clearer therapeutic approach for patients with ACOS is required.

Multicenter Study Observational StudyDelayed but successful response to noninvasive ventilation in COPD patients with acute hypercapnic respiratory failure.
We evaluated a new noninvasive ventilation (NIV) protocol that allows the pursuit of NIV in the case of persistent severe respiratory acidosis despite a first NIV challenge in COPD patients with acute hypercapnic respiratory failure (AHRF). ⋯ Most of the COPD patients with AHRF have a successful outcome when NIV is pursued despite a persistent severe respiratory acidosis after the first NIV trial. The outcome of delayed responders is similar to the one of the early responders. On the contrary, the second episode of AHRF during the hospital stay carries a poor prognosis.

Multicenter Study Observational StudyActive smoking and COPD phenotype: distribution and impact on prognostic factors.
Smoking can affect both the phenotypic expression of COPD and factors such as disease severity, quality of life, and comorbidities. Our objective was to evaluate if the impact of active smoking on these factors varies according to the disease phenotype. ⋯ Active smoking is more common among exacerbator phenotypes and appears to affect quality of life and dyspnea grade differently, depending on the clinical expression of the disease.

Randomized Controlled TrialEffects of a simple prototype respiratory muscle trainer on respiratory muscle strength, quality of life and dyspnea, and oxidative stress in COPD patients: a preliminary study.
The aim of this study was to evaluate the efficiency of a simple prototype device for training respiratory muscles in lung function, respiratory muscle strength, walking capacity, quality of life (QOL), dyspnea, and oxidative stress in patients with COPD. ⋯ This study proposes that a simple prototype device can be used clinically in COPD patients as a standard device to train respiratory muscles, improving lung function and QOL, as well as involving MDA and NO levels.
