EVIDENCE FOR EXPANDING INVASIVE MEDIASTINAL STAGING FOR PERIPHERAL T1 LUNG TUMORS.
Guidelines recommend invasive mediastinal staging for patients with non-small cell lung cancer and a "central" tumor. However, there is no consensus definition for central location. As such, the decision to perform invasive staging largely remains on an empirical foundation. ⋯ Our data indicate a high rate of N2 metastasis among T1 tumors and no significant relationship between tumor diameter or location. This suggests that patients with small, peripheral lung cancers may benefit from invasive mediastinal staging.

Patterns and impact of arterial CO2 management in patients with Acute Respiratory Distress Syndrome: Insights from the LUNG SAFE study.
Considerable variability exists regarding CO2 management in early ARDS, with the impact of arterial CO2 tension on management and outcomes poorly understood. ⋯ No evidence was found for benefit or harm with hypercapnia. Of concern, ICU mortality was higher with sustained hypocapnia in mild to moderate ARDS.

Ultrasound examination of the thorax is superior to chest radiograph or physical examination for diagnosing common conditions such as pneumonia, pulmonary edema, pleural effusion, and pneumothorax. The basic skill set is straightforward to learn, quick to perform, repeatable, and does not involve patient transport, harmful ionizing radiation, or waiting time. This paper outlines the basic building blocks that makeup a thoracic ultrasound examination, regardless of which specific scanning protocol is performed. Narrative videos and illustrative figures demonstrating these techniques are included.

Association of Cigarette Type and Nicotine Dependence in Patients Presenting for Lung Cancer Screening.
Over decades, there have been several alterations to cigarettes, including the addition of filters and flavoring. However, lung cancer remains the leading cause of cancer-related death in the United States. ⋯ In a screening population, the type of cigarette smoked is associated with different levels of dependence. Eliciting type of cigarette and time to first cigarette has the potential to allow for tailored tobacco treatment interventions within this context.

Bronchopulmonary dysplasia (BPD), first described by Northway in 1967, is a process of neonatal lung injury that is most strongly associated with prematurity. The "old" form of the disease associated with the oxidative damage and volutrauma from perinatal mechanical ventilation has been increasingly supplanted by a "new" form resulting from interrupted growth of the lung at earlier stages of fetal development. Given the significant improvement in the survival of children with BPD since the 1980s, many more of these patients are living into adulthood and are being seen in adult pulmonary practices. ⋯ Additional factors shown to affect the lives of adult BPD survivors are also discussed. Finally, we discuss insights into the process of transitioning these complex patients from pediatric to adult pulmonary practices. As survivors of BPD enter adulthood and continue to require specialty pulmonary care, awareness of the disease's varied manifestations and responses to treatment will become increasingly important.
