The Utility of Assessing Alexithymia, in Addition to Coping, in the Context of Posttraumatic Stress.

The distinction between alexithymia and coping in relation to posttraumatic stress has not been fully explored. The present study examined the extent to which alexithymia explained unique variance in posttraumatic stress, beyond the variance explained by coping, in a sample of trauma-exposed adults ( N = 706; M age = 19.41 years, SD = 1.

Conversion of PROMIS global health to EQ-5D health state values in patients undergoing lumbar spine surgery: A psychometric evaluation.

This study seeks to validate the conversion of PROMIS-GH scores to EQ-5D Health Utility Index (HUI) values. Patients undergoing lumbar spine surgery were prospectively surveyed using EQ-5D-3L and PROMIS-GH short form instruments. EQ-5D-HUI scores, and PROMIS scores converted to HUI were calculated.

Bundled Payments for Appendectomy: a Model of Financial Implications to Institutions.

Background: Bundled payments are increasingly becoming common in surgery, yet little is known regarding their potential impact on reimbursements for patients presenting with acute appendicitis. This study examines the financial impact of bundled payments for acute appendicitis.

Methods: This was a retrospective review of all open or laparoscopic appendectomies between July 2014 and June 2017.

Confidence limits on one-stage model parameters in benchmark risk assessment.

In modern environmental risk analysis, inferences are often desired on those low dose levels at which a fixed benchmark risk is achieved. In this paper, we study the use of confidence limits on parameters from a simple one-stage model of risk historically popular in benchmark analysis with quantal data. Based on these confidence bounds, we present methods for deriving upper confidence limits on extra risk and lower bounds on the benchmark dose.

Simultaneous Confidence Bands for Abbott-Adjusted Quantal Response Models.

We study use of a Scheffé-style simultaneous confidence band as applied to low-dose risk estimation with quantal response data. We consider two formulations for the dose-response risk function, an Abbott-adjusted Weibull model and an Abbott-adjusted log-logistic model. Using the simultaneous construction, we derive methods for estimating upper confidence limits on predicted extra risk and, by inverting the upper bands on risk, lower bounds on the benchmark dose, or BMD, at which a specific level of 'benchmark risk' is attained.

Swallowing disorders in trauma patients: impact of tracheostomy.

Tracheostomy is associated with increased aspiration rates, and swallowing disorders have not been well-studied in trauma patients with tracheostomy. Swallowing evaluations were conducted in 224 patients (102 trauma and 122 nontrauma patients). Half of the patients in each group had tracheostomies.

New anatomic repair of midline abdominal wall incisions extending to suprapubic region.

This article describes a new technique to close infraumbilical midline abdominal wall incisions extending to the suprapubic region. This repair is technically easy to perform, saves time, reduces the risk of bowel and bladder injury and takes into consideration the anatomical landmarks of the peritoneum, the rectus sheath and the arcuate line. Abdominal wall closure with this repair is especially useful in obese patients.

Role of the physician versus the patient in the detection of recurrent disease following treatment for head and neck cancer.

Objectives/hypothesis: Objective evidence supporting current National Comprehensive Cancer Network guidelines regarding surveillance of patients treated for head and neck cancer is presently lacking. The study examines the relative role of current surveillance methods on disease detection in this patient population.

Study Design: Prospective nonrandomized study.
