We established that children who weigh more and who gain weight at an appropriate and uninterrupted rate have a better FEV(1) trajectory. Aggressive nutritional support to maintain growth in these children may therefore improve FEV(1), which can be taken as a surrogate for better lung health, and may ultimately lead to better survival.

To focus on effective patient safety strategies in an environment of intense competition for resources, a method of quantifying the effect of potential sources of medical errors was developed. This study assessed excess length of stay (LOS) and hospitalization costs associated with patients who experienced errors. The distribution of the errors occurring within the mean LOS experienced by others with the same diagnosis and severity was also examined. Patients with errors had longer stays and greater costs when compared to controls.
