A Certified Registered Nurse Anesthetist's Transition to Manager.

The purpose of this exploratory qualitative study was twofold: (1) to identify common experiences or barriers that arise during the first year as Certified Registered Nurse Anesthetists (CRNAs) move into management and (2) to identify knowledge, skills, abilities, and resources needed to ensure a smooth and successful career transition for new CRNA managers. A sample of 18 current and past CRNA managers participated in one-on-one phone interviews using a 16-question, semistructured interview protocol. Interview data were analyzed for emergent themes using qualitative data analysis software.

Intrinsic versus laser-induced fluorescence spectroscopy for coronary atherosclerosis: a generational comparison model for testing diagnostic accuracy.

Laser-induced fluorescence (LIF) and intrinsic fluorescence spectroscopy (IFS) have been used experimentally for diagnosing coronary atherosclerosis. In this study, we demonstrated the diagnostic superiority of IFS at 342-nm excitation (IFS(342)) versus LIF (LIF(342)) and described a protocol for head-to-head comparison of old (LIF) versus new (IFS) generations of similar diagnostic methods, labeled as "generational comparison model". IFS(342) and LIF(342) were modeled with basis spectra of media, fibrous caps, and superficial foam cells and of their correspondent chemicals (elastin, collagen, and lipoproteins).

Viscosity in infant dysphagia management: comparison of viscosity of thickened liquids used in assessment and thickened liquids used in treatment.

The purpose of this study was to investigate comparability of viscosity of liquids used in assessment and treatment of infants with dysphagia. Goals of this study were as follows: (1) Establish baseline viscosity values for (a) the commercial barium assessment liquids of varying thicknesses and (b) clinically typical infant formula thickened with varied thickeners. (2) Compare the baseline viscosities of the various liquids for correlation of values.

Fingerprint and high-wavenumber Raman spectroscopy in a human-swine coronary xenograft in vivo.

Intracoronary Raman spectroscopy could open new avenues for the study and management of coronary artery disease due to its potential to measure the chemical and molecular composition of coronary atherosclerotic lesions. We have fabricated and tested a 1.5-mm-diameter (4.
