Randomized Controlled Trial Multicenter Study
Virtual bronchoscopic navigation combined with endobronchial ultrasound to diagnose small peripheral pulmonary lesions: a randomised trial.
Bronchoscopy using endobronchial ultrasound (EBUS) can help to diagnose small peripheral pulmonary lesions. However, although biopsy sites can be confirmed, a bronchoscope cannot be guided in EBUS. Virtual bronchoscopic navigation (VBN) can guide a bronchoscope with virtual images, but its value has not been confirmed. ⋯ The diagnostic yield for small peripheral pulmonary lesions is increased when VBN is combined with EBUS. Clinical trial number UMIN000000569.

There are epidemiological studies indicating that exposure to metal fumes is a risk factor for infectious pneumonia. Whether occupational exposure to other agents, such as inorganic dust or chemicals, also increases the risk for infectious pneumonia is not clear. The aim of the present study was to elucidate whether occupational exposure to respiratory pollutants and irritants increases the risk for infectious pneumonia. ⋯ Our findings indicate that exposure to inorganic dust increases the mortality from infectious pneumonias, especially lobar pneumonia and pneumococcal pneumonia. The mechanism is unclear, but the effect may be mediated through induced airways inflammation.

Randomized Controlled Trial Multicenter Study
Multimodal nutritional rehabilitation improves clinical outcomes of malnourished patients with chronic respiratory failure: a randomised controlled trial.
In chronic respiratory failure (CRF), body composition strongly predicts survival. ⋯ Multimodal nutritional rehabilitation aimed at improving body composition increased exercise tolerance, quality of life in women and survival in compliant patients, supporting its incorporation in the treatment of malnourished patients with CRF. Clinical Trial number NCT00230984.

Randomized Controlled Trial Multicenter Study
Effect of an action plan with ongoing support by a case manager on exacerbation-related outcome in patients with COPD: a multicentre randomised controlled trial.
An individualised action plan (AP) is a potentially effective method of helping patients with chronic obstructive pulmonary disease (COPD) to recognise and anticipate early exacerbation symptoms. This multicentre randomised controlled trial evaluates the hypothesis that individualised APs reduce exacerbation recovery time. ⋯ This study shows that an individualised AP, including ongoing support by a case manager, decreases the impact of exacerbations on health status and tends to accelerate recovery. APs can be considered a key component of self-management programmes in patients with COPD.

Multicenter Study
Do asbestos-related pleural plaques on HRCT scans cause restrictive impairment in the absence of pulmonary fibrosis?
It is uncertain whether isolated pleural plaques cause functional impairment. ⋯ The results show a relationship between isolated parietal and/or diaphragmatic pleural plaques and a trend towards a restrictive pattern, although the observed decrease in FVC and TLC is unlikely to be of real clinical relevance for the majority of subjects in this series.
