Lung cancer (LC) is frequently associated with idiopathic pulmonary fibrosis (IPF). Despite this well-known association, the outcome of LC in patients with IPF is unclear. The objective of this study was to evaluate the impact of LC on survival of patients with associated IPF. ⋯ In patients with IPF, LC has a significant adverse impact on survival. Diagnosis and treatment of LC in IPF are burdened by an increased incidence of severe complicating events, apparently as lethal as the cancer itself.

COPD remains a leading cause of morbidity and mortality. The objectives of this study were to estimate (1) national US COPD-attributable annual medical costs by payer (direct) and absenteeism (indirect) in 2010 and projected medical costs through 2020 and (2) state-specific COPD-attributable medical and absenteeism costs in 2010. ⋯ Costs attributable to COPD and its sequelae are substantial and are projected to increase through 2020. Evidence-based interventions that prevent tobacco use and reduce the clinical complications of COPD may result in potential decreased COPD-attributable costs.

Comparative Study
Endothelial Function in Children with Obstructive Sleep Apnea and the Effects of Adenotonsillectomy.
The association between childhood OSA and endothelial function as measured by flow-mediated dilation (FMD) and its response to OSA treatment are uncertain. The objective of this study was to compare FMD in children with OSA with nonsnoring control subjects and to examine its response to treatment. ⋯ Children with OSA had reduced FMD, which was reversible with treatment.

The Centers for Disease Control and Prevention has shifted policy away from using ventilator-associated pneumonia (VAP) and toward using ventilator-associated conditions (VACs) as a marker of ICU quality. To date, limited prospective data regarding the incidence of VAC among medical and surgical ICU patients, the ability of VAC criteria to capture patients with VAP, and the potential clinical preventability of VACs are available. ⋯ Although relatively uncommon, VACs are associated with greater mortality and morbidity when they occur. Most VACs represent nonpreventable events, and the VAC criteria capture a minority of VAP episodes.
