Data regarding the sensitivity of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for staging of lung cancer in patients with radiographic N0 disease is scant and inconsistent. With increasing use of nonoperative ablative therapies, studies focusing on the performance characteristics of EBUS-TBNA in this population are important. ⋯ This is the largest report of EBUS-TBNA in patients with N0 disease by "integrated" PET-CT. The majority of false-negative EBUS results were in LN stations outside its reach. In our study, both sensitivity and NPV of EBUS-TBNA were lower than early reports despite more extensive LN sampling. Given the high false-negative rate of imaging modalities, EBUS-TBNA may still play an important role in patients with radiographic N0 disease, particularly when nonsurgical ablative therapies are planned. Prospective studies are needed to corroborate our findings in the nonsurgical population.

Randomized Controlled Trial Multicenter Study
Hospital patterns of mechanical ventilation for patients with exacerbations of COPD.
Randomized trials have shown that noninvasive ventilation (NIV) can reduce the need for intubation and improve the survival of patients with severe exacerbations of chronic obstructive pulmonary disease (COPD); however, it is not known whether hospitals with greater use of NIV achieve lower rates of intubation and better patient outcomes. ⋯ Use of NIV as the initial ventilation strategy for patients with COPD varies considerably across hospitals. Institutions with greater use of NIV have lower rates of invasive mechanical ventilation and better patient outcomes.

Tissue fibrosis, a major cause of death worldwide, leads to significant organ dysfunction in any organ of the human body. In the lung, fibrosis critically impairs gas exchange, tissue oxygenation, and immune function. Idiopathic pulmonary fibrosis (IPF) is the most detrimental and lethal fibrotic disease of the lung, with an estimated median survival of 50% after 3-5 years. ⋯ CLAD affects up to 50% of all transplanted lungs after 5 years, and is characterized by small airway obstruction with pronounced epithelial injury, aberrant wound healing, and subepithelial and interstitial fibrosis. Intriguingly, the mechanisms leading to the fibrotic processes in the engrafted lung exhibit striking similarities to those in IPF; therefore, antifibrotic therapies may contribute to increased graft function and survival in CLAD. In this review, we focus on these common fibrosis-related mechanisms in IPF and CLAD, comparing and contrasting clinical phenotypes, the mechanisms of fibrogenesis, and biomarkers to monitor, predict, or prognosticate disease status.

Resuscitation programs such as Advanced Cardiac Life Support, Cardiac Life Support, Pediatric Advanced Life Support, and the Neonatal Resuscitation Program offer inadequate guidance to physicians who must ultimately decide when to stop resuscitation efforts. These decisions involve clinical and ethical judgments and are complicated by communication challenges, group dynamics, and family considerations. This article presents a framework, summarized in a mnemonic (CEASE: Clinical Features, Effectiveness, Ask, Stop, Explain), for how to stop resuscitation efforts and communicate that decision to clinicians and ultimately the patient's family. Rather than a decision rule, this mnemonic represents a framework based on best evidence for when physicians are considering stopping resuscitation efforts and provides guidance on how to communicate that decision.

Multicenter Study Comparative Study Observational Study
Comparison between an alternative and the classic definition of chronic bronchitis in COPDGene.
Previous studies on chronic bronchitis (CB) have used varying definitions. ⋯ The SGRQ CB definition identifies more subjects with chronic cough and sputum who share a similar phenotype identified by the Classic CB definition. The addition of the SGRQ CB definition to the classic one can be used to identify more patients with chronic obstructive pulmonary disease at risk for poor outcomes.
