Upper Gastrointestinal Series in the Workup for Pediatric Gastrostomy Placement: Does it Delay Care?

Introduction: Upper gastrointestinal (UGI) series is often part of the workup prior to the placement of gastrostomy tubes in children. Prior studies have suggested UGI to be limited in utility and an extra financial burden. The goal of this study was to investigate the utility and cost of UGI studies.

The gender equity gap: A multistudy investigation of within-job inequality in equity-based awards.

Laws in many countries mandate paying men and women equally when in similar jobs. Such laws, coupled with considerable organizational efforts, lead some scholars to contend that within-job pay inequality is no longer a source of the gender pay gap. We argue important differences in a widely used form of pay heretofore overlooked in existing studies-equity-based awards (i.

High-Frequency Nonlinear Doppler Contrast-Enhanced Ultrasound Imaging of Blood Flow.

Current methods for in vivo microvascular imaging (<1 mm) are limited by the tradeoffs between the depth of penetration, resolution, and acquisition time. Ultrasound Doppler approaches combined at elevated frequencies (<7.5 MHz) are able to visualize smaller vasculature and, however, are still limited in the segmentation of lower velocity blood flow from moving tissue.

Contrast-Enhanced Ultrasound for Assessment of Local Hemodynamic Changes Following a Rodent Contusion Spinal Cord Injury.

Introduction: Severe trauma to the spinal cord leads to a near complete loss of blood flow at the injury site along with significant hypoperfusion of adjacent tissues. Characterization and monitoring of local tissue hypoperfusion is currently not possible in clinical practice because available imaging techniques do not allow for assessment of blood flow with sufficient spatial and temporal resolutions. The objective of the current study was to determine whether ultrafast contrast-enhanced ultrasound (CEUS) imaging could be used to visualize and quantify acute hemodynamic changes in a rat traumatic spinal cord injury (SCI) model.
