A scoping review of preoperative weight loss interventions on postoperative outcomes for patients with gastrointestinal cancer.

Background: Obesity is associated with increased risk of surgical complications in some settings.

Objective: As a precursor to a systematic review, we conducted a scoping review of intentional preoperative weight loss to describe these interventions, their feasibility and effectiveness for patients with gastrointestinal cancer.

Methods: In April 2024, Ovid MEDLINE, EMBASE, CINAHL, and Google Scholar were searched for primary studies of intentional weight loss before elective gastrointestinal cancer surgery.

Simulation in Learning and Using the Nutrition Care Process/Terminology: Experiences and Perceptions of Dietitians in Canada.

To investigate experiences with, and perceptions of, simulation in learning and using the Nutrition Care Process/Terminology (NCP/T) of dietitians in Canada. In February-March 2017, a convenience sample of 382 dietitians in Canada (71.8% in clinical practice) completed an online survey regarding the type(s), setting(s), and perceptions of the simulations in which they engaged in learning and using the NCP/T.

Conductivities and transport properties of gelled electrolytes with and without an ionic liquid for Li and Li-ion batteries.

Conductivity and transport properties have been determined for gelled polymer electrolytes of three compositions: a base PVdF-polymer gel with organic carbonate solvents as plasticizers and LiN(SO(2)C(2)F(5))(2) electrolyte, a second polymer electrolyte with 5 mass % 1-ethyl-3-methylimidazolium bisperfluoroethylsulfonyl imide (EMI-BETI) added to the base polymer electrolyte, and a third PVdF polymer electrolyte using only EMI-BETI as the plasticizer. Conductivities were studied over the temperature range +25 to -40 degrees C, and for all three gels, the temperature dependence of the conductivities was found to follow the VTF equation, which is consistent with the free volume model for ion transport. For the gel containing 5 mass % EMI-BETI, transport numbers were determined from +50 to -20 degrees C and were found to decrease as the temperature decreased.
