Significance of NT-pro-BNP in acute exacerbation of COPD patients without underlying left ventricular dysfunction.
B-type natriuretic peptide (BNP) and the N-terminal fragment of pro-BNP (NT-pro-BNP) are established biomarkers of heart failure. Increased levels of natriuretic peptide (NP) have been associated with poor outcomes in acute exacerbation of COPD (AECOPD); however, most studies did not address the conditions that can also increase NT-pro-BNP levels. We aimed to determine if NT-pro-BNP levels correlate with outcomes of AECOPD in patients without heart failure and other conditions that can affect NT-pro-BNP levels. ⋯ Patients with AECOPD and elevated NT-pro-BNP levels had increased hospital length of stay and need for intensive care. Based on our study, serum NT-pro-BNP levels cannot be used as a biomarker for increased mortality or requirement for invasive or noninvasive ventilation in this group of patients.

Observational StudyA retrospective study to assess clinical characteristics and time to initiation of open-triple therapy among patients with chronic obstructive pulmonary disease, newly established on long-acting mono- or combination therapy.
An incremental approach using open-triple therapy may improve outcomes in patients with chronic obstructive pulmonary disease (COPD). However, there is little sufficient, real-world evidence available identifying time to open-triple initiation. ⋯ In this population, patients with COPD are more likely to initiate open-triple therapy following LAMA therapy, compared with ICS/LABA therapy. Further research is required to identify factors associated with the need for treatment augmentation among patients with COPD.

The use of the practice walk test in pulmonary rehabilitation program: National COPD Audit Pulmonary Rehabilitation Workstream.
Our aim was to evaluate the use and impact of the practice walk test on enrolment, completion, and clinical functional response to pulmonary rehabilitation (PR) using the 2015 UK National Chronic Obstructive Pulmonary Disease (COPD) Pulmonary Rehabilitation audit data. Patients were assessed according to whether a baseline practice walk test was performed or not. Study outcomes included use of the practice walk test, baseline and change in incremental shuttle walk test distance (ISWD) or 6-minute walk test distance (6MWD), and enrolment to and completion of PR program. ⋯ Although the change in ISWD and 6MWD with PR was lower in the practice walk test group, they walked further at discharge assessment. Only 22.6% of the patients in the 2015 National PR audit had a practice walk test at assessment. Those who did had better enrolment, completion, and better baseline walking distance, from which the prescription is set.

Cost-effectiveness of the Aerobika* oscillating positive expiratory pressure device in the management of COPD exacerbations.
COPD places a huge clinical and economic burden on the US health care system, with acute exacerbations representing a key driver of direct medical costs. Current treatments, although effective in reducing symptoms and limiting exacerbations, do not adequately target the underlying disease processes that drive exacerbation development. The Aerobika* oscillating positive expiratory pressure (OPEP) device has been shown in a real-world effectiveness study to lower the frequency of moderate-to-severe exacerbations during a 30-day post-exacerbation period. This study sought to determine the impact on exacerbations and costs and to determine the cost-effectiveness of the Aerobika* device. ⋯ The Aerobika* device is a cost-effective treatment option that provides clinical benefit and results in direct medical cost savings in a post-exacerbation care COPD population.

Identification of subtypes in subjects with mild-to-moderate airflow limitation and its clinical and socioeconomic implications.
The purpose of this study was to identify subtypes in patients with mild-to-moderate airflow limitation and to appreciate their clinical and socioeconomic implications. ⋯ Clinical and epidemiological heterogeneities of subjects with mild-to-moderate airflow limitation and a different level of health care utilization by each subtype are shown. Identification of a subtype with high health care demand could be a priority for effective utilization of limited resources.
