The American Board of Anesthesiology recently introduced the BASIC Examination, a component of its new staged examinations for primary certification, typically offered to residents at the end of their first year of clinical anesthesiology training. This analysis tested the hypothesis that the introduction of the BASIC Examination was associated with an acceleration of knowledge acquisition during the residency training period, as measured by increments in annual In-Training Examination scores. ⋯ These results support the hypothesis that the introduction of the BASIC Examination is associated with accelerated knowledge acquisition in residency training and provides evidence for the value of the new staged system in promoting desired educational outcomes of anesthesiology training.

Recently, the U. S. Food and Drug Administration issued an official warning to all practicing physicians regarding potentially detrimental behavioral and cognitive sequelae of an early exposure to general anesthesia during in utero and in early postnatal life. ⋯ Although human evidence is limited and controversial, a large body of scientific evidence gathered from several mammalian species demonstrates that there is a potential foundation for concern. Considering this new development in public awareness, this review focuses on nonhuman primates because their brain development is the closest to humans in terms of not only timing and duration, but in terms of complexity as well. The review compares those primate findings to previously published work done with rodents.

Amyloid deposition is a potential contributor to postoperative cognitive dysfunction. The authors hypothesized that 6-week global cortical amyloid burden, determined by F-florbetapir positron emission tomography, would be greater in those patients manifesting cognitive dysfunction at 6 weeks postoperatively. ⋯ In this study, postoperative cognitive dysfunction was not associated with 6-week cortical amyloid deposition. The relationship between cognitive dysfunction and regional amyloid burden and the rate of postoperative amyloid deposition merit further investigation.
