Meta Analysis
The Effect of Alcohol Consumption on the Risk of ARDS: A Systematic Review and Meta-analysis.
To conduct a systematic review and meta-analysis evaluating the association between alcohol consumption and the risk of ARDS in adults. ⋯ Chronic high alcohol consumption significantly increases the risk of ARDS. This finding suggests that patients admitted to hospital should be screened for chronic alcohol use.

Tobacco Dependence Predicts Higher Lung Cancer and Mortality Rates and Lower Rates of Smoking Cessation in the National Lung Screening Trial.
Incorporating tobacco treatment within lung cancer screening programs has the potential to influence cessation in high-risk smokers. We aimed to better understand the characteristics of smokers within a screening cohort, correlate those variables with downstream outcomes, and identify predictors of continued smoking. ⋯ Using TTFC, a one-question assessment of tobacco dependence, at the time of lung cancer screening has implications for personalizing tobacco treatment and improving risk assessment.

Meta Analysis
The Relationship Between COPD and Frailty: A Systematic Review and Meta-Analysis of Observational Studies.
Frailty is common in seniors and is characterized by diminished physiological reserves and increased vulnerability to stressors. Frailty can change the prognosis and treatment approach of several chronic diseases, including COPD. The association between frailty and COPD has never been systematically reviewed. ⋯ Frailty and pre-frailty are common in individuals with COPD. Older subjects with COPD have a two-fold increased odds of frailty. These results may have clinical implications, as they identify the need to assess frailty in individuals with COPD and to further investigate any potential negative effects associated with the co-occurrence of these conditions. Longitudinal research that examines temporal associations between COPD and frailty are needed to further clarify this relationship and to assess if treatment of COPD may prevent the onset of frailty.

Multicenter Study Observational Study
Baseline and Serial Brain Natriuretic Peptide Level Predicts 5-Year Overall Survival in Patients With Pulmonary Arterial Hypertension: Data From the REVEAL Registry.
Plasma brain natriuretic peptide (BNP) level is a prognostic biomarker in pulmonary arterial hypertension (PAH). Its impact on long-term overall survival (OS) was investigated in the Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management (REVEAL), a 5-year observational, multicenter, US registry of patients with PAH. ⋯ Baseline BNP threshold of 340 pg/mL strongly predicted survival up to 5 years in patients with PAH. A BNP reduction at 1 year since enrollment was associated with decreased mortality risk, whereas an increase in BNP at 1 year was associated with an increased mortality risk, supporting BNP as a surrogate marker of PAH survival.
