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.

There is no standardized system to grade pleural effusion size on CT scans. A validated, systematic grading system would improve communication of findings and may help determine the need for imaging guidance for thoracentesis. ⋯ A simple, two-step decision rule for sizing pleural effusions on CT scans improves interobserver agreement from moderate to substantial levels.

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.
