Recent observational studies have suggested that use of statins reduces mortality in patients suffering from chronic obstructive pulmonary disease. However, no meta-analysis has reported the pooled hazard ratio of statins to all-cause mortality. ⋯ The use of statins for patients suffering from chronic obstructive pulmonary disease may reduce all-cause mortality. This conclusion should be re-evaluated by a registered large-scale randomized controlled trial.

Meta Analysis Comparative Study
Comparative efficacy of long-acting bronchodilators for COPD: a network meta-analysis.
Clinicians are faced with an increasingly difficult choice regarding the optimal bronchodilator for patients with chronic obstructive pulmonary disease (COPD) given the number of new treatments. The objective of this study is to evaluate the comparative efficacy of indacaterol 75/150/300 μg once daily (OD), glycopyrronium bromide 50 μg OD, tiotropium bromide 18 μg/5 μg OD, salmeterol 50 μg twice daily (BID), formoterol 12 μg BID, and placebo for moderate to severe COPD. ⋯ In terms of trough FEV1 and SGRQ score indacaterol, glycopyrronium, and tiotropium are expected to be the most effective bronchodilators.

Review Meta Analysis
The role of pirfenidone in the treatment of idiopathic pulmonary fibrosis.
Idiopathic pulmonary fibrosis (IPF) is a progressive disease, with a median survival time of 2-5 years. The search for effective treatment has involved numerous clinical trials of investigational agents without significant success. However, in 2011, pirfenidone was the first drug to be approved for the treatment of IPF in Europe. ⋯ Pirfenidone was generally well tolerated, with the most common side effects being gastrointestinal and photosensitivity. Data from the RECAP extension phase of the CAPACITY studies, where patients were treated with pirfenidone for up to three years, further support the manageable tolerability profile of pirfenidone. The efficacy data, coupled with long-term safety data, provide further evidence of a clinically-meaningful treatment effect with pirfenidone in patients with IPF.

Review Meta Analysis
The prognostic value of pulmonary embolism severity index in acute pulmonary embolism: a meta-analysis.
Prognostic assessment is important for the management of patients with acute pulmonary embolism (APE). Pulmonary Embolism Severity Index (PESI) and simple PESI (sPESI) are new emerged prognostic assessment tools for APE. The aim of this meta-analysis is to assess the accuracy of the PESI and the sPESI to predict prognostic outcomes (all-cause and PE-related mortality, serious adverse events) in APE patients, and compare between these two PESIs. ⋯ PESI has discriminative power to predict the short-term death and adverse outcome events in patients with acute pulmonary embolism, the PESI and the sPESI have similar accuracy, while sPESI is easier to use. However, the calibration for predicting prognosis can't be calculated from this meta-analysis, some prospective studies for accessing PESI predicting calibration can be recommended.

Review Meta Analysis
Clinical use of exhaled volatile organic compounds in pulmonary diseases: a systematic review.
There is an increasing interest in the potential of exhaled biomarkers, such as volatile organic compounds (VOCs), to improve accurate diagnoses and management decisions in pulmonary diseases. The objective of this manuscript is to systematically review the current knowledge on exhaled VOCs with respect to their potential clinical use in asthma, lung cancer, chronic obstructive pulmonary disease (COPD), cystic fibrosis (CF), and respiratory tract infections. A systematic literature search was performed in PubMed, EMBASE, Cochrane database, and reference lists of retrieved studies. ⋯ The heterogeneity of studies challenged the inter-laboratory comparability. In conclusion, profiles of VOCs are potentially able to accurately diagnose various pulmonary diseases. Despite these promising findings, multiple challenges such as further standardization and validation of the diverse techniques need to be mastered before VOCs can be applied into clinical practice.
