Since 2008, severe cases of emerging human adenovirus (HAdV) type 55 (HAdV-55) were reported sporadically in China. But no comparative studies had been conducted to discern the differences in epidemiologic and clinical abnormalities between HAdV-55 and other types (HAdV-7, HAdV-3, HAdV-14, HAdV-50, and HAdV-C). ⋯ HAdV-55 has established itself as a major pneumonia pathogen in the Chinese population, and further surveillance and monitoring of this agent as a cause of CAP is warranted.

The passage of health-care reform and current efforts in payment reform signal the beginning of a significant transformation of the US health-care system. An entire new set of structures is being developed to facilitate increased access to care that is cost-effective and of high quality. As described in The Institute of Medicine report "Crossing the Quality Chasm," our nation is charting a path toward quality health care that aims to be safe, efficient, effective, timely, patient-centered, and equitable. ⋯ Third, as part of our care redesign, we must assure that we are prepared to meet the ethical challenges ahead and reassert the importance of equity, fairness, and caring as key building blocks of a new care delivery system. As we move ahead, it is critical to assure that our health-care system is culturally competent and has the capacity to deliver high-quality care for all, while eliminating disparities and assuring equity. Disparities are unjust, unethical, costly, and unacceptable-and integrating strategies to achieve equity as part of our health-care system's transformation will give us an incredible opportunity to comprehensively address them.

Multicenter Study
No association of 25-hydroxyvitamin D with exacerbations in primary care patients with COPD.
Cross-sectional studies suggest an association of 25-hydroxyvitamin D with exacerbations in patients with COPD, but longitudinal evidence from cohort studies is scarce. The aim of this study was to assess the association of serum 25-hydroxyvitamin D with exacerbations and mortality in primary care patients with COPD. ⋯ This longitudinal study in a real-world COPD population that carefully minimized misclassification of exacerbations and the influence of confounding did not show an association of 25-hydroxyvitamin D with exacerbations and mortality.
