Randomized Controlled Trial
Efficacy and comfort of volume-guaranteed pressure support in patients with chronic ventilatory failure of neuromuscular origin.
Although non-invasive ventilation is widely used for the management of patients with neuromuscular disease, it remains unclear which ventilatory mode is associated with optimal patient-ventilator interaction and provides more effective gas exchange. The effects of volume-guaranteed pressure support (PSV-VTG) as compared with pressure support ventilation (PSV) and assisted pressure controlled ventilation (APCV) on breathing pattern and patient-ventilator synchrony during sleep, blood gases and subjective comfort were evaluated in a group of stable patients with neuromuscular disease. ⋯ PSV-VTG did not outperform older modes of ventilation in terms of efficacy on breathing pattern and blood gases. In addition, application of PSV-VTG was associated with a higher rate of patient-ventilator dyssynchrony.

Controlled Clinical Trial
Assessment and learning curve evaluation of endobronchial ultrasound skills following simulation and clinical training.
Endobronchial ultrasound is a revolutionary diagnostic pulmonary procedure. The use of a computer endobronchial ultrasound simulator could improve trainee procedural skills before attempting to perform procedures on patients. This study aims to compare endobronchial ultrasound performance following training with simulation versus conventional training using patients. ⋯ Using an endobronchial ultrasound simulator leads to more rapid acquisition of skill in endobronchial ultrasound compared with conventional training methods, as assessed by an endobronchial ultrasound simulator. Endobronchial ultrasound simulators show promise for training with the advantage of minimizing the burden of procedural learning on patients.

The value of dual-time- point (18) F-FDG PET was investigated to predict the prognosis of patients with pulmonary sarcoidosis. ⋯ RI-SUV showed better diagnostic accuracy compared with early SUV or (67) Ga uptake, in patients with persistent lung involvement at 1year. It may be a useful measure of persistent inflammation in patients with pulmonary sarcoidosis.
