Overcoming Barriers to the Use of Osteopathic Manipulation Techniques in the Emergency Department

Background: Osteopathic Manipulation Techniques (OMT) have been shown to be effective therapeutic modalities in various clinical settings, but appear to be underutilized in the emergency department (ED) setting.Objective: To examine barriers to the use of OMT in the ED and provide suggestions to ameliorate these barriers.Methods: Literature reviewResults: While the medical literature cites numerous obstacles to the use of OMT in the ED setting, most can be positively addressed through education, careful planning, and ongoing research into use of these techniques. Recent prospective clinical trials of OMT have demonstrated the utility of these modalities.Conclusion: Osteopathic Manipulation Techniques are useful therapeutic modalities that could be utilized to a greater degree in the ED. As the number of osteopathic emergency physicians increases, the opportunity to employ these techniques should increase.[WestJEM. 2009;10:184-189.

Accommodation and Coping in Medieval Catholic England: A Historical Dramaturgy Casebook for The Chester Mystery Cycle’s Play 14: Christ at the House of Simon the Leper, Christ and the Moneylenders, and Judas’ Plot

In this historically focused dramaturgy casebook for the medieval Catholic Chester Mystery Cycle\u27s Play 14, Christ at the House of Simon the Leper, Christ and the Moneylenders, and Judas’ Plot, I offer suggestions for Play 14\u27s production as it might have appeared in the cycle\u27s final year of performance, 1575. I contextualize and grapple with the play\u27s antisemitisms, and also offer a brief history of antisemitism in medieval Europe. I also analyze Play 14 and the Chester Mystery Cycle for their rhetorical appeals to the medieval vernacular language, contexts, and events, as well as their anachronistic temporal and geographic translation of the biblical imaginary into the medieval Cestrian world. I argue and display that these appeals promoted a heightened sense of religious contemplation, and prompted reflection on lived, not idealized devotion in an authentic world, and helped medieval Cestrians cope with, or accomodate for life in perplexing and tumultuous medieval times

“A Certain Brauch:” German-Georgian Palatine and Rhenish Immigrant Houses in Columbia County, New York and their Vernacular Architectural Roots

In this archaeological and architectural survey of 18th Century Palatine and Rhenish immigrant houses in New York\u27s Hudson Valley, specifically in Columbia County, I track the development of three houses from their earliest vernacular forms to those touched by the Georgian influence. The Georgian worldview, stemming from European Enlightenment ideals, began permeating colonial American society in the 18th Century. It\u27s influence first began to touch the wealthy and elite most connected with mother Europe, and then trickled into more common society. I chronicle and analyze Germantown, NY\u27s Reformed Sanctity Church Parsonage, Germantown, NY\u27s Simeon Rockefeller House, and Clermont, NY\u27s Stone Jug for their adherence to and deviation from vernacular Rhenish architectural forms, as well as their journey to the Georgianized, or German-Georgian forms in which they sit today. I also begin to analyze the development of these houses for ethnohistorically supported potential implications on worldview, and the development of Palatine culture in Colonial New York

Modeling the HD32297 Debris Disk with Far-IR Herschel Data

HD32297 is a young A-star (~30 Myr) 112 pc away with a bright edge-on debris disk that has been resolved in scattered light. We observed the HD32297 debris disk in the far-infrared and sub-millimeter with the Herschel Space Observatory PACS and SPIRE instruments, populating the spectral energy distribution (SED) from 63 to 500{\mu}m. We aimed to determine the composition of dust grains in the HD32297 disk through SED modeling, using geometrical constraints from the resolved imaging to break degeneracies inherent in SED modeling. We found the best fitting SED model has 2 components: an outer ring centered around 110 AU, seen in the scattered light images, and an inner disk near the habitable zone of the star. The outer disk appears to be composed of grains > 2{\mu}m consisting of silicates, carbonaceous material, and water ice with an abundance ratio of 1:2:3 respectively and 90% porosity. These grains appear consistent with cometary grains, implying the underlying planetesimal population is dominated by comet-like bodies. We also discuss the 3.7{\sigma} detection of [C II] emission at 158{\mu}m with the Herschel PACS Spectrometer, making HD32297 one of only a handful of debris disks with circumstellar gas detected.Comment: 11 pages, 4 figures, accepted for publication in The Astrophysical Journa

Volatile-Rich Circumstellar Gas in the Unusual 49 Ceti Debris Disk

We present Hubble Space Telescope STIS far-UV spectra of the edge-on disk around 49 Ceti, one of the very few debris disks showing sub-mm CO emission. Many atomic absorption lines are present in the spectra, most of which arise from circumstellar gas lying along the line-of-sight to the central star. We determined the line-of-sight CI column density, estimated the total carbon column density, and set limits on the OI column density. Surprisingly, no line-of-sight CO absorption was seen. We discuss possible explanations for this non-detection, and present preliminary estimates of the carbon abundances in the line-of-sight gas. The C/Fe ratio is much greater than the solar value, suggesting that 49 Cet harbors a volatile-rich gas disk similar to that of Beta Pictoris.Comment: Accepted for publication in ApJ Letters. 5 pages, 4 figure
