Review Meta Analysis
Pulmonary rehabilitation as a mechanism to reduce hospitalizations for acute exacerbations of chronic obstructive pulmonary disease: A systematic review and meta-analysis.
Acute exacerbation of COPD (AECOPD) has a significant impact on health-care use, including physician visits and hospitalizations. Previous studies and reviews have shown that pulmonary rehabilitation (PR) has many benefits, but the effect on hospitalizations for AECOPD is inconclusive. ⋯ Although results from RCTs suggested that PR reduces subsequent admissions, pooled results from the cohort studies did not, likely reflecting the heterogeneous nature of individuals included in observational research and the varying standard of PR programs.

Review
Occupational and Environmental Contributions to Chronic Cough in Adults: Chest Expert Panel Report.
In response to occupational and environmental exposures, cough can be an isolated symptom reflecting exposure to an irritant with little physiological consequence, or it can be a manifestation of more significant disease. This document reviews occupational and environmental contributions to chronic cough in adults, focusing on aspects not previously covered in the 2006 ACCP Cough Guideline or our more recent systematic review, and suggests an approach to investigation of these factors when suspected. ⋯ Despite increased understanding of cough related to occupational and environmental triggers, there remains a gap between the recommended assessment of occupational and environmental causes of cough and the reported systematic assessment of these factors. There is a need for further documentation of occupational and environmental causes of cough in the future.
