Randomized Controlled Trial
Umeclidinium in patients with COPD: a randomised, placebo-controlled study.
Efficacy and safety of umeclidinium administered in a dry power inhaler were evaluated in moderate-to-very-severe chronic obstructive pulmonary disease patients. This was a randomised, placebo-controlled study assessing once-daily umeclidinium 62.5 and 125 μg over 12 weeks. The primary end-point was change from baseline in trough forced expiratory volume in 1 s (FEV1) on day 85. ⋯ Significant improvements in least squares mean transitional dyspnoea index focal score for UMEC 125 mg(1.3 units; p,0.05) and change from baseline St George's Respiratory Questionnaire total score for both UMEC doses (-7.9 and -10.87 units, for UMEC 62.5 mg and 125 mg, respectively; both p,0.001) were noted compared with placebo at week 12 [DOSAGE ERROR CORRECTED]. The incidence of adverse events was low and similar across treatments. Umeclidinium 62.5 and 125 μg significantly improved lung function, dyspnoea and health status compared with placebo, and were well tolerated in chronic obstructive pulmonary disease patients over 12 weeks.

Randomized Controlled Trial
Endobronchial ultrasound-guided cryobiopsies in peripheral pulmonary lesions: a feasibility study.
Peripheral lung lesions are sometimes difficult to reach even with endobronchial ultrasound (EBUS) and insufficient material is often obtained by transbronchial forceps biopsy. Cryoprobes can be used for performing tissue biopsies. We evaluated the safety and feasibility of the cryoprobe in combination with EBUS for the diagnosis of peripheral lung lesion. ⋯ We observed one case of moderate bleeding. Transbronchial cryobiopsy with EBUS guidance is safe and useful to obtain histological samples. Larger tissue samples can be obtained by cryoprobe.
