Management of Patients with Predicted Difficult Airways in an Academic Emergency Department.

Background: Patients with difficult airways are sometimes encountered in the emergency department (ED), however, there is a little data available regarding their management.

Objectives: To determine the incidence, management, and outcomes of patients with predicted difficult airways in the ED.

Methods: Over the 1-year period from July 1, 2015 to June 30, 2016, data were prospectively collected on all patients intubated in an academic ED.

Detection of in vivo enzyme activity with CatalyCEST MRI.

Purpose: CatalyCEST MRI compares the detection of an enzyme-responsive chemical exchange saturation transfer (CEST) agent with the detection of an unresponsive "control" CEST agent that accounts for other conditions that influence CEST. The purpose of this study was to investigate the feasibility of in vivo catalyCEST MRI.

Methods: CEST agents that were responsive and unresponsive to the activity of urokinase plasminogen activator were shown to have negligible interaction with each other.
