NCT01229514
General anesthetic medications have been shown to cause neuronal cell death in the brains of infant rodents. Ethanol and general anesthetics both act on NMDA and GABA receptors,and appear to have similar mechanisms of toxicity in the immature rodent brain. Functional MRI (fMRI) is a technique developed for mapping brain activation and has been utilized to examine how the brains of children with a history of early exposure to ethanol function differently from children without such a history. This study will utilize fMRI to look for specific changes in brain activation patterns in children with a history of early exposure to general anesthesia, as compared to children without such exposure.
NCT00976027
The aim of this study is to determine the efficacy of Fluzone High Dose vaccine and that of Fluzone® vaccine in the elderly. Primary objective: To measure the efficacy of the vaccine, defined as the prevention of laboratory-confirmed influenza caused by viral types/subtypes that are antigenically similar to those contained in the respective annual vaccine formulations. Secondary objectives: * To compare the clinical efficacy of Fluzone High Dose vaccine with that of Fluzone® vaccine in elderly adults, with respect to laboratory-confirmed influenza illness caused by any type or subtype of influenza virus. * To compare the clinical efficacy of Fluzone High Dose vaccine with that of Fluzone® vaccine in elderly adults, in preventing culture-confirmed influenza illness caused by viral types/subtypes antigenically similar to those contained in the respective annual vaccine formulations.
