Multicenter Study Comparative Study
Sex, race, and the development of acute lung injury.
Prior studies suggest that mortality differs by sex and race in patients who develop acute lung injury (ALI). Whether differences in presentation account for these disparities remains unclear. We sought to determine whether sexual and racial differences exist in the rate of ALI development and ALI-related mortality after accounting for differences in clinical presentations. ⋯ Sex and race differences exist in the clinical presentation of patients at risk of developing ALI. After accounting for differences in presentation, there was no sex difference in ALI development and outcome. Black patients were less likely to develop ALI despite increased severity of illness on presentation.

Randomized Controlled Trial
Everolimus plus octreotide long-acting repeatable in patients with advanced lung neuroendocrine tumors: analysis of the phase 3, randomized, placebo-controlled RADIANT-2 study.
The incidence of neuroendocrine tumors (NETs) has increased approximately fivefold since the 1980s. A similar increase in the incidence of lung NETs has been reported, but therapy has not been optimized. ⋯ This exploratory subgroup analysis of the RADIANT-2 trial indicates that in patients with advanced lung NET, the addition of everolimus to octreotide LAR improves median PFS by 2.4-fold compared with placebo plus octreotide LAR. These clinically significant observations support the continued evaluation of everolimus treatment regimens in this patient population.

In 2008, lung cancer replaced liver cancer as the number one cause of death among people with malignant tumors in China. The registered lung cancer mortality rate increased by 464.84% in the past 3 decades, which imposes an enormous burden on patients, health-care professionals, and society. We performed a systematic review of the published data on lung cancer in China between 1990 and 2011 to analyze the incidence and mortality rates, economic burden, and risk factors of cancer and the effectiveness of interventions. ⋯ Continuous efforts should be concentrated on education of the general public regarding lung cancer to increase prevention and early detection. Specific interventions need to be implemented to reduce smoking rates and environmental risk factors. Standardized treatment protocols should be adapted in China.

Multicenter Study Comparative Study
Comparison of 21-gauge and 22-gauge aspiration needle in endobronchial ultrasound-guided transbronchial needle aspiration: results of the American College of Chest Physicians Quality Improvement Registry, Education, and Evaluation Registry.
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive procedure originally performed using a 22-gauge (22G) needle. A recently introduced 21-gauge (21G) needle may improve the diagnostic yield and sample adequacy of EBUS-TBNA, but prior smaller studies have shown conflicting results. To our knowledge, this is the largest study undertaken to date to determine whether the 21G needle adds diagnostic benefit. ⋯ There is no difference in specimen adequacy or diagnostic yield between the 21G and 22G needle groups. EBUS-TBNA in conjunction with rapid onsite cytologic evaluation and a 21G needle is associated with fewer needle passes compared with a 22G needle.

Obstructive sleep apnea (OSA) is a strong and independent risk factor for the development of hypertension, particularly resistant hypertension, and cardiovascular diseases. Patients with resistant hypertension have a high prevalence of OSA in association with elevated aldosterone levels, high salt intake, and salt-sensitive BP. The objective of this study was to determine whether dietary salt and aldosterone are associated with severity of OSA in patients with resistant hypertension. ⋯ The findings suggest that dietary salt is related to the severity of OSA in patients with resistant hypertension and hyperaldosteronism. The results support dietary salt restriction as a treatment strategy for reduction of OSA severity in these patients.
