The postprandial secretion of peptide YY and in obesity is differentially increased after gastric bypass versus sleeve gastrectomy.

Objectives: Peptide tyrosine tyrosine (PYY) exists as two species, PYY and PYY , with distinct effects on insulin secretion and appetite regulation. The detailed effects of bariatric surgery on PYY and PYY secretion are not known as previous studies have used nonspecific immunoassays to measure total PYY. Our objective was to characterize the effect of sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) on fasting and postprandial PYY and PYY secretion using a newly developed liquid chromatography-tandem mass spectrometry (LC-MS/MS) assay.

Early treatment with anti-tumor necrosis factor agents improves long-term effectiveness in symptomatic stricturing Crohn's disease.

Background: There is limited evidence on the effectiveness of biological therapy in stricturing complications in patients with Crohn's disease.

Aim: The study aims to determine the effectiveness of anti-tumor necrosis factor (TNF) agents in Crohn's disease complicated with symptomatic strictures.

Methods: In this multicentric and retrospective study, we included adult patients with symptomatic stricturing Crohn's disease receiving their first anti-TNF therapy, with no previous history of biological, endoscopic or surgical therapy.

Psychosocial adaptation and cellular immunity in breast cancer patients in the weeks after surgery: An exploratory study.

Background: The period just after surgery for breast cancer requires psychosocial adaptation and is associated with elevated distress. Distress states have been associated with decreased cellular immune functioning in this population, which could have negative effects on physical recovery. However, little is known about relations between psychological status [negative and positive mood states and overall quality of life (QOL)] and cellular signaling cytokines that could account for these associations in women undergoing treatment for breast cancer.

Disparities in vocational rehabilitation services and outcomes for Hispanic clients with traumatic brain injury: do they exist?

Objective: Examine disparities in vocational rehabilitation (VR) services for Hispanic clients with traumatic brain injury.

Design: Logistic regression analysis of secondary data.

Participants: Five thousand eight hundred thirty-one European American and Hispanic clients.

Influence of dietary vitamin E on behavior of Listeria monocytogenes and color stability in ground turkey meat following electron beam irradiation.

There is growing concern that the free radical scavenging effect of antioxidants added to meats might reduce the antimicrobial effectiveness of ionizing radiation. A study was conducted to determine the effect of vitamin E on the behavior (growth) of Listeria monocytogenes and color stability in turkey meat following electron beam irradiation. Raw ground turkey breast meat from birds fed diets containing 0 (control), 50, 100, and 200 IU/kg of vitamin E was inoculated with a five-strain mixture of L.
