The purpose of this article is to provide an update on evidence-based methods for mediastinal staging in patients with lung cancer. This is a review of the recently published studies and a summary of relevant guidelines addressing the role of CT scan, PET scan, endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA), and mediastinoscopy as pertinent to lung cancer staging and restaging. ⋯ Several studies, meta-analyses, and systematic reviews specifically targeted the role of PET scan, EBUS-TBNA, and mediastinoscopy for detecting mediastinal lymph node involvement in patients suffering from lung cancer. Based on the recommendations from the currently published guidelines, algorithms of care are proposed for staging and restaging of the mediastinum.

Comparative Study Clinical Trial
PERCUTANEOUS DILATATIONAL TRACHEOSTOMY WITH A DOUBLE LUMEN ENDOTRACHEALTUBE: A COMPARISON OF FEASIBILITY, GAS-EXCHANGE AND AIRWAY PRESSURES.
Gas exchange and airway pressures are markedly altered during percutaneous dilatational tracheostomy (PDT). A double-lumen endotracheal tube (DLET) has been developed for better airway management during PDT. The current study prospectively evaluated the in vivo feasibility, gas exchange, and airway pressures during PDT with DLET compared with a conventional endotracheal tube (ETT). ⋯ PDT with DLET can be performed safely without difficulties limiting the technique. Furthermore, during PDT, the use of the DLET resulted in more stable gas exchange, airway pressures, and ventilation than PDT with a conventional ETT.

OSA is a common yet underdiagnosed respiratory disorder characterized by recurrent upper airway obstruction during sleep. OSA results in sleep fragmentation and repetitive hypoxemia and is associated with a variety of adverse consequences including excessive daytime sleepiness, reduced quality of life, cardiovascular disease, decreased learning skills, and neurocognitive impairment. Neurocognitive impairments that have been linked to poor sleep include memory deficits, decreased learning skills, inability to concentrate, and decreased alertness. ⋯ It is increasingly recognized that OSA may also have substantial economic consequences. Specifically, there is accumulating evidence implicating OSA as an important contributor to work disability (including absenteeism, presenteeism) and work-related injuries. This review summarizes the current state of knowledge in these two areas.

The Hospital Readmissions Reduction Program (HRRP) penalizes hospitals for 30-day readmissions and was extended to COPD in October 2014. There is limited evidence available on readmission risk factors and reasons for readmission to guide hospitals in initiating programs to reduce COPD readmissions. ⋯ Medicare patients with COPD exacerbations are usually not readmitted for COPD, and these reasons differ depending on PAC use. Readmitted patients are more likely to be dually enrolled in Medicare and Medicaid, suggesting that the addition of COPD to the readmissions penalty may further worsen the disproportionately high penalties seen in safety net hospitals.

Short telomeres are a common defect in idiopathic pulmonary fibrosis, yet mutations in the telomerase genes account for only a subset of these cases. ⋯ Our findings identify TINF2 as a mutant telomere gene in familial pulmonary fibrosis and suggest that infertility may precede the presentation of pulmonary fibrosis in a small subset of adults with telomere syndromes.
