Randomized Controlled TrialA randomized controlled trial of telephone-mentoring with home-based walking preceding rehabilitation in COPD.
With the limited reach of pulmonary rehabilitation (PR) and low levels of daily physical activity in chronic obstructive pulmonary disease (COPD), a need exists to increase daily exercise. This study evaluated telephone health-mentoring targeting home-based walking (tele-rehab) compared to usual waiting time (usual care) followed by group PR. ⋯ Telephone-mentoring for home-based walking demonstrated no benefit to exercise capacity. Two 6-minute walking tests at each time-point may not be necessary. Supervised exercise seems essential in PR. The challenge of incorporating exercise into daily life in COPD is substantial.

Impact of combined pulmonary fibrosis and emphysema on surgical complications and long-term survival in patients undergoing surgery for non-small-cell lung cancer.
The outcome of radical surgery for lung cancer was investigated in patients with combined pulmonary fibrosis and emphysema (CPFE). ⋯ CPFE patients have a poorer prognosis than those with emphysema alone or with normal lung on CT finding. The intensive evaluation of preoperative CT images is important, and radical surgery for lung cancer should be decided carefully when patients concomitantly harbor CPFE, because of unfavorable prognosis.

Comparative StudyImportance of fractional exhaled nitric oxide in the differentiation of asthma-COPD overlap syndrome, asthma, and COPD.
Fractional exhaled nitric oxide (FeNO) is an easy, sensitive, reproducible, and noninvasive marker of eosinophilic airway inflammation. Accordingly, FeNO is extensively used to diagnose and manage asthma. Patients with COPD who share some of the features of asthma have a condition called asthma-COPD overlap syndrome (ACOS). The feasibility of using FeNO to differentiate ACOS patients from asthma and COPD patients remains unclear. ⋯ FeNO measurement is an easy, noninvasive, and sensitive method for differentiating ACOS from COPD. This technique is a new perspective for the management of COPD patients.

Prevalence of and risk factors for postoperative pulmonary complications after lung cancer surgery in patients with early-stage COPD.
This study aimed to investigate whether the prevalence of postoperative pulmonary complications (PPCs) in patients with non-small-cell lung cancer (NSCLC) is even higher in the early stages of COPD than in such patients with normal lung function and to verify the usefulness of symptom- or quality of life (QoL)-based scores in predicting risk for PPCs. ⋯ Even in patients with early-stage COPD, the prevalence of PPCs is higher than in patients with NSCLC with normal spirometry. However, this rate is not different between group A and group B patients with COPD. In accordance with this, scores based on symptoms or QoL are not predictors of risk of PPCs in patients with early-stage COPD.

Comparative StudyAsthma-chronic obstructive pulmonary disease overlap syndrome in the urban Chinese population: prevalence and disease burden using the 2010, 2012, and 2013 China National Health and Wellness Surveys.
Research has suggested a significant burden for patients with asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS). However, few studies have studied this population in the People's Republic of China, a region in the midst of rapid epidemiological change with respect to respiratory disease. The aim of this study was to assess the prevalence of ACOS and its association with patient outcomes in urban China. ⋯ Patients with ACOS have a greater comorbidity burden and significantly worse health outcomes compared with COPD only patients and matched controls. Better management of these patients may help to improve their outcomes.
