Objective: Recent literature studying the impact of blood transfusion on outcomes in patients with head and neck cancer (HNC) have shown that blood transfusions are associated with increased risk of death and higher wound infection rates. The purpose of this study was to implement a lower transfusion threshold while comparing outcomes of free flap patients following initiation of a new transfusion guideline.

Methods: A retrospective study of all patients at a tertiary care academic center who underwent free tissue transfer after HNC resection between July 17, 2007 and June 7, 2021.

Article Synopsis
  • The Higgs boson, crucial for the standard model of particle physics, helps mediate the weak force between elementary particles, and its mass is closely regulated by the model's symmetries.
  • Researchers measured the mass of the boson using data from proton-antiproton collisions at the Tevatron collider, accumulating about 4 million candidates to achieve a very precise measurement.
  • This new mass measurement shows a significant discrepancy with what is expected from the standard model, suggesting potential gaps in our current understanding of particle physics.

The CDF and D0 experiments at the Fermilab Tevatron have measured the asymmetry between yields of forward- and backward-produced top and antitop quarks based on their rapidity difference and the asymmetry between their decay leptons. These measurements use the full data sets collected in proton-antiproton collisions at a center-of-mass energy of sqrt[s]=1.96  TeV.

Objectives: Home health aides (HHAs) work in a high-risk industry and experience high rates of work-related injury that have been significantly associated with reduction in workers and organisational productivity, quality and performance. The main objective of the study was to examine how worker environment and ergonomic factors affect HHA risk for reporting occupational injuries.

Method: We used cross-sectional analysis of data from the 2007 National Home Health and Hospice Aide Survey (NHHAS).

The objectives of the study were to profile occupational injury patterns across home health and hospice care (HHC), organization characteristics, and home health aides' (HHAs) individual characteristics, and examine how worker training affects HHAs' risk of reporting an injury using the model of human factors of health care in the home. The authors measured training knowledge using an 11-item scale and conducted univariate and bivariate analyses to describe injury patterns across individual, occupational, and organizational factors using STATA 12.0.

Combined constraints from the CDF and D0 Collaborations on models of the Higgs boson with exotic spin J and parity P are presented and compared with results obtained assuming the standard model value JP=0+. Both collaborations analyzed approximately 10  fb(-) of proton-antiproton collisions with a center-of-mass energy of 1.96 TeV collected at the Fermilab Tevatron.

A search for particles with the same mass and couplings as those of the standard model Higgs boson but different spin and parity quantum numbers is presented. We test two specific alternative Higgs boson hypotheses: a pseudoscalar Higgs boson with spin-parity J^{P}=0^{-} and a gravitonlike Higgs boson with J^{P}=2^{+}, assuming for both a mass of 125  GeV/c^{2}. We search for these exotic states produced in association with a vector boson and decaying into a bottom-antibottom quark pair.

Background: After ileocolic resection in Crohn's disease, studies concerning the influence of the laparoscopic or open approach on clinical and endoscopic recurrences are scarce.

Patients And Methods: In a prospective database, we identified all patients operated on between 2004 and 2012 for primary ileocolic resection in Crohn's disease, with at least 6 months of follow-up. The rates of endoscopic recurrence during the first postoperative year and the clinical recurrence at any time during follow-up were measured and compared after the laparoscopic or open approach.

A multisite cluster randomized trial was conducted to examine the effects of the Social Skills Improvement System Classwide Intervention Program (SSIS-CIP; Elliott & Gresham, 2007) on students' classroom social behavior. The final sample included 432 students across 38 second grade classrooms. Social skills and problem behaviors were measured via the SSIS rating scale for all participants, and direct observations were completed for a subsample of participants within each classroom.
