Computed tomography (CT) and magnetic resonance imaging (MRI) can provide detailed anatomic structures and quantitative function information for chronic obstructive pulmonary disease (COPD). ⋯ There were different features and correlations between PFT, CT volume and MR perfusion in different phenotype, indicating each phenotype may have novel imaging method guiding clinical management.

Computed tomography pulmonary arterial obstruction index ratio (CTPAOIR) is related with the severity of pulmonary embolism (PE). Platelet indices including mean platelet volume (MPV), platelet distribution width (PDW) are reported to be increased in acute PE. ⋯ Platelet indices, MPV and PDW, can be used for the determination of disease severity, and lead to therapeutic strategies for PE patients.

Pneumonia is often diagnosed among patients hospitalized with acute exacerbations of chronic obstructive pulmonary disease (AECOPD). The aims of this study were to find the proportion of patients with pneumonia among admissions due to AECOPD and whether pneumonia has impact on the length of stay (LOS), usage of non-invasive ventilation (NIV) or the in-hospital mortality. ⋯ In-hospital morbidity, but not mortality, was increased among admissions with pAECOPD compared to npAECOPD. This may, in part, be explained by the extensive treatment with antibiotics and NIV in patients with pAECOPD.

Randomized Controlled Trial
Inhaled fluticasone furoate/vilanterol does not affect hypothalamic-pituitary-adrenal axis function in adolescent and adult asthma: randomised, double-blind, placebo-controlled study.
Fluticasone furoate (FF) is a novel inhaled corticosteroid with 24-h activity. FF is in development as a once-daily treatment for asthma as monotherapy and in combination with vilanterol (VI), a long-acting β2 agonist. Corticosteroids can have systemic effects on hypothalamic-pituitary-adrenal (HPA) axis function, potentially resulting in cortisol suppression. ⋯ FF/VI was found to be non-inferior to placebo on HPA axis function, with no indication of significant cortisol suppression after 42 days.

Comparative Study
Readmissions for COPD: propensity case-matched comparison between pulmonary and non-pulmonary departments.
Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is a common cause of hospitalisation, and the readmission rate is high. We aimed to determine whether patients discharged from a pulmonary department (PD) after an AECOPD episode had a lower COPD-related readmission rate during the next 12 months than comparable patients discharged from other internal medicine departments (ODs). ⋯ There was little difference in COPD-related readmission rates between comparable patients discharged from the PD and the ODs after an AECOPD during 1 year following the index admission.
