Comparative Study
Comparing peak and submaximal cardiorespiratory responses during field walking tests with incremental cycle ergometry in COPD.
Field and laboratory-based tests are used to measure exercise capacity in people with COPD. A comparison of the cardiorespiratory responses to field tests, referenced to a laboratory test, is needed to appreciate the relative physiological demands. We sought to compare peak and submaximal cardiorespiratory responses to the 6-min walk test, incremental shuttle walk test and endurance shuttle walk test with a ramp cycle ergometer test (CET) in patients with COPD. ⋯ In patients with moderate COPD, field walking tests elicited a similar peak rate of oxygen uptake and heart rate as a CET, demonstrating that both self- and externally paced walking tests progress to high intensities.

COPD and bronchial asthma are chronic airway diseases with a different pathogenesis. Comparisons of differences in airway calibre by bronchial generation between these diseases and their importance to pulmonary function have not been fully studied. We investigated airway calibre and wall thickness in relation to pulmonary function in patients with asthma, COPD, asthma plus emphysema and normal subjects using CT. ⋯ Airway calibre in asthma may be smaller than in COPD. Airflow limitations correlated more closely with peripheral Ai in patients with asthma plus emphysema than in patients with asthma alone.

The review aims to discuss current concepts in advance care planning (ACP) for patients with COPD, and to provide a narrative review of recent trends in ACP and end-of-life care for patients with COPD. ACP, which involves patient-clinician communication about end-of-life care, can improve outcomes for patients and their families, and may be especially relevant for patients with COPD. Effective patient-clinician communication is needed to inform and prepare patients about their diagnosis, treatment, prognosis and what dying might be like. ⋯ ACP should be implemented alongside curative-restorative care for patients with advanced COPD. The disease course of COPD is such that there will rarely be a clear transition point predicting the timing of the need for initiation of end-of-life care. Future studies should focus on interventions that facilitate concurrent ACP and prepare patients for making in-the-moment decisions, with the goal of improving the quality of end-of-life care.

Multicenter Study
Prescription of antibiotics for adults hospitalized with community-acquired pneumonia in Korea in 2004: a population-based descriptive study.
Community-acquired pneumonia (CAP) is generally considered to be a major cause of morbidity and mortality. There is much controversy regarding the optimal choice of antibiotics for patients with CAP. The aim of this study was to identify the antibiotics prescribed for adults hospitalized with CAP in Korea during a calendar year. ⋯ In this study, patterns of antimicrobial prescription for patients hospitalized with CAP were assessed for the first time in Korea. There was divergence from the 2009 Korean guidelines for the treatment of CAP, reinforcing the need for assessment of physicians' adherence to the guidelines.
