Review Meta Analysis Comparative Study
Tiotropium versus placebo for inadequately controlled asthma: a meta-analysis.
This meta-analysis was performed to evaluate the efficacy and safety of the addition of tiotropium to standard treatment regimens for inadequately controlled asthma. ⋯ The addition of tiotropium to standard treatment regimens has significantly improved lung function without increasing adverse events in patients with inadequately controlled asthma. Long-term trials are required to assess the effects of the addition of tiotropium on asthma exacerbations and mortality.

Randomized Controlled Trial Comparative Study
A randomized trial comparing the diagnostic yield of rigid and semirigid thoracoscopy in undiagnosed pleural effusions.
Thoracoscopic pleural biopsy increases the diagnostic yield of pleural effusions undiagnosed after thoracentesis and is superior to closed pleural biopsy. Medical thoracoscopy can be performed using the rigid thoracoscope or the semirigid thoracoscope (pleuroscope). In this randomized trial, we compare the efficacy and safety of the 2 thoracoscopes. ⋯ Rigid thoracoscopy was found to be superior to semirigid thoracoscopy overall, but the diagnostic yield was similar if pleural biopsy could be successfully performed. Due to the small sample size, a larger study is required to define the usefulness and choice between the 2 procedures. (ClinicalTrials.gov registration NCT01726556).

Randomized Controlled Trial
Expiratory Rib Cage Compression, Secretion Clearance and Respiratory Mechanics in Mechanically Ventilated Patients: A Randomized Crossover Trial.
Expiratory rib cage compression (ERCC) has been empirically used by physiotherapists with the rationale of improving expiratory flows and therefore the airway clearance in mechanically ventilated patients. This study evaluates the acute mechanical effects and sputum clearance of an ERCC protocol in ventilated patients with pulmonary infection. ⋯ Although ERCC increases expiratory flow, it has no clinically relevant effects from improving the sputum production and respiratory mechanics in hypersecretive mechanically ventilated patients. The maneuver can cause EFL in some patients. (ClinicalTrials.gov registration NCT01525121).

Alpha-1 antitrypsin deficiency is under-recognized. We hypothesized that respiratory therapists (RTs) could help improve the detection rate of individuals with alpha-1 antitrypsin deficiency. The American Association for Respiratory Care (AARC) and Alpha-1 Foundation recently collaborated to create an online alpha-1 antitrypsin deficiency training program for RTs. This study aimed to determine (1) the rate of RT enrollment in the training program, (2) the rates of detecting individuals with alpha-1 antitrypsin deficiency referred for testing by RTs who took the online course ("trained RTs"), and (3) the genotype distribution of referred individuals found to have alpha-1 antitrypsin deficiency. ⋯ A program to educate RTs about alpha-1 antitrypsin deficiency was associated with referral of patients for alpha-1 antitrypsin deficiency testing and high rates of detecting individuals with severe alpha-1 antitrypsin deficiency.
