Patient Satisfaction With Propofol for Outpatient Colonoscopy: A Prospective, Randomized, Double-Blind Study.

Background: Previous literature has shown that propofol has ideal anesthetic properties for patients undergoing colonoscopy, a common procedure at outpatient surgery centers. However, there is a paucity of information regarding patient satisfaction with propofol.

Objective: The aim of this study was to evaluate patient satisfaction with propofol compared with nonpropofol (fentanyl/midazolam) anesthesia for outpatient colonoscopies.

On the structure of grain/interphase boundaries and interfaces.

Grain/interphase boundaries/interfaces of varying misorientations, free volume fractions, curvatures and irregularities are present in materials, both 3D and 2D, regardless of whether these materials are crystalline or amorphous/glassy. Therefore, a question arises about the central idea on which a general description of grain/interphase boundaries/interfaces can and should be based. It is suggested that a generalized model of a structural/basic unit (crystalline, non-crystalline or of any scale), which depends on the interatomic (including electronic) interactions, the spatial distribution of the atoms and electrons, the number of atoms and free volume fraction present in the structural/basic unit and the experimental conditions should serve the purpose.

Clinical evaluation of a flexible fecal incontinence management system.

Background: Management of fecal incontinence is a priority in acute and critical care to reduce risk of perineal dermatitis and transmission of nosocomial infections.

Objective: To evaluate the safety of the Flexi-Seal Fecal Management System in hospitalized patients with diarrhea and incontinence.

Methods: A prospective, single-arm clinical study with 42 patients from 7 hospitals in the United States was performed.

Structural basis for bending of organic crystals.

Bending is observed in organic crystals when the packing is anisotropic in such a way that strong and weak interaction patterns occur in nearly perpendicular directions.
