Observational Study
A comparison of ultrafast and conventional spectral Doppler ultrasound to measure cerebral blood flow velocity during inguinal hernia repair in infants.
Ultrafast cerebral Doppler ultrasound enables simultaneous quantification and visualization of cerebral blood flow velocity. The aim of this study is to compare the use of conventional and ultrafast spectral Doppler during anesthesia and their potential to show the effect of anesthesiologic procedures on cerebral blood flow velocities, in relation to blood pressure and cerebral oxygenation in infants undergoing inguinal hernia repair. ⋯ It is possible to quantify cortical blood flow velocity during general anesthesia using conventional and ultrafast spectral Doppler cerebral ultrasound. Cerebral blood flow velocity and blood pressure decreased, while regional cerebral oxygenation increased during general anesthesia. Ultrafast spectral Doppler ultrasound offers novel insights into perfusion within the cerebral cortex, unattainable through conventional spectral ultrasound. Yet, ultrafast Doppler is curtailed by a lower success rate and a more rigorous learning curve compared to conventional method.

Observational Study
External validation of a predictive model for reintubation after cardiac surgery: A retrospective, observational study.
Explore validation of a model to predict patients' risk of failing extubation, to help providers make informed, data-driven decisions regarding the optimal timing of extubation. ⋯ Future work is needed to explore how to optimize models before local implementation.

An important mission of academic medical departments is to further the scholarship and education of its junior faculty. In 2013, Hindman et al. described the design and initial outcomes of a faculty development program for junior faculty at the University of Iowa Department of Anesthesia. In the current study, we reassessed whether the program increased the production of publications long-term. We included all department faculty, years before joining the department, and years after leaving the department, to control for the effects of simply being current faculty in the department, benefiting from its resources, and having had progressively more experience working. ⋯ A faculty development program for junior faculty can reliably increase the production of publications in an anesthesiology department by at least one per year. However, there is considerable heterogeneity in publication production among faculty.
