OBJECTIVE: To determine whether there is an increased odds of mortality among trauma patients treated at hospitals with higher proportions of minority patients (ie, black and Hispanic patients combined).

DESIGN: Hospitals were categorized on the basis of the percentage of minority patients admitted with trauma. The adjusted odds of in-hospital mortality were compared between hospitals with less than 25% of patients who were minorities (the reference group) and hospitals with 25% to 50% of patients who were minorities and hospitals with more than 50% of patients who were minorities. Multivariate logistic regression (with generalized linear modeling and a cluster-correlated robust …

A 2-Step Approach To Myeloablative Haploidentical Stem Cell Transplantation: A Phase 1/2 Trial Performed With Optimized T-Cell Dosing., Dolores Gross, Matthew Carabasi, Joanne Filicko-O'Hara, Margaret Kasner, John L Wagner, Beth Colombe, Patricia Cornett Farley, William O'Hara, Phyllis Flomenberg, Maria Werner-Wasik, Janet Brunner, Bijoyesh Mookerjee, Terry Hyslop, Mark Weiss, Neal Flomenberg

Department of Medical Oncology Faculty Papers

Studies of haploidentical hematopoietic stem cell transplantation (HSCT) have identified threshold doses of T cells below which severe GVHD is usually absent. However, little is known regarding optimal T-cell dosing as it relates to engraftment, immune reconstitution, and relapse. To begin to address this question, we developed a 2-step myeloablative approach to haploidentical HSCT in which 27 patients conditioned with total body irradiation (TBI) were given a fixed dose of donor T cells (HSCT step 1), followed by cyclophosphamide (CY) for T-cell tolerization. A CD34-selected HSC product (HSCT step 2) was infused after CY. A dose of 2 × 10(8)/kg …

Cardiovascular Magnetic Resonance Myocardial Feature Tracking Detects Quantitative Wall Motion During Dobutamine Stress., Andreas Schuster, Shelby Kutty, Asif Padiyath, Victoria Parish, Paul Gribben, David A. Danford, Marcus R. Makowski, Boris Bigalke, Philipp Beerbaum, Eike Nagel

Journal Articles: Pediatrics

BACKGROUND: Dobutamine stress cardiovascular magnetic resonance (DS-CMR) is an established tool to assess hibernating myocardium and ischemia. Analysis is typically based on visual assessment with considerable operator dependency. CMR myocardial feature tracking (CMR-FT) is a recently introduced technique for tissue voxel motion tracking on standard steady-state free precession (SSFP) images to derive circumferential and radial myocardial mechanics.We sought to determine the feasibility and reproducibility of CMR-FT for quantitative wall motion assessment during intermediate dose DS-CMR.

METHODS: 10 healthy subjects were studied at 1.5 Tesla. Myocardial strain parameters were derived from SSFP cine images using dedicated CMR-FT software (Diogenes MRI prototype; …

Polycyclic Aromatic Hydrocarbons In Maternal And Umbilical Cord Blood From Pregnant Hispanic Women Living In Brownsville, Texas, Ken Sexton, Jennifer J Salinas, Thomas J Mcdonald, Rose M Z Gowen, Rebecca P Miller, Joseph B Mccormick, Susan P Fisher-Hoch

Faculty, Staff and Student Publications

Venous blood was drawn from 35 pregnant Hispanic women living in Brownsville, Texas, and matched cord blood was collected at birth. Gas chromatography/mass spectrometry was used to measure concentrations of 55 individual PAHs or groups of PAHs. Results indicate that these women and their fetuses were regularly exposed to multiple PAHs at comparatively low concentrations, with levels in cord blood generally exceeding levels in paired maternal blood. While the possibility of related adverse effects on the fetus is uncertain, these exposures in combination with socioeconomically-disadvantaged and environmentally-challenging living conditions raise legitimate public health concerns.

To evaluate sex-based differences in darunavir/ritonavir-based therapy, the Gender, Race And Clinical Experience (GRACE) study was designed to enroll and retain a high proportion of women representative of the racial/ethnic demographics of women with HIV/AIDS in the United States. The recruitment and retention strategies used in GRACE are described in this article.

METHODS: Recruitment and retention strategies targeting women included selecting study sites that focused on women, involving community consultants, site-specific enrollment plans, access to other ARV drugs, study branding, site and patient toolkits, targeted public relations, …

A Test Of The Role Of The Medial Temporal Lobe In Single-Word Decoding., Karol Osipowicz, Tyler Rickards, Atif Shah, Ashwini Sharan, Michael Sperling, Waseem Kahn, Joseph Tracy

Department of Neurology Faculty Papers

The degree to which the MTL system contributes to effective language skills is not well delineated. We sought to determine if the MTL plays a role in single-word decoding in healthy, normal skilled readers. The experiment follows from the implications of the dual-process model of single-word decoding, which provides distinct predictions about the nature of MTL involvement. The paradigm utilized word (regular and irregularly spelled words) and pseudoword (phonetically regular) stimuli that differed in their demand for non-lexical as opposed lexical decoding. The data clearly showed that the MTL system was not involved in single word decoding in skilled, native …

The Texas Heart Institute Journal

In this study, we established a new index by combining several echocardiographic parameters to quantify heart failure. We selected 233 consecutive patients who underwent both echocardiographic and plasma B-type natriuretic peptide (BNP) tests within 24 hours after referral for suspected heart failure. The echocardiographic parameters included systolic function, diastolic function, left ventricular chamber remodeling, valvular lesions, systolic pulmonary arterial pressure, and regional wall-motion abnormality. Each factor was scored from 1 to 3 points according to its severity. The total point from these 6 factors is the echocardiographic multi-parameter score (EMPS).

The EMPS for 37, 51, 77, and 38 patients from …

Basal Insulin Requirements On Continuous Subcutaneous Insulin Infusion During The First 12 Months After Diagnosis Of Type 1 Diabetes Mellitus., Neesha Ramchandani, Mary Kristine Ellis, Shobhit Jain, Sonal Bhandari, Henry Anhalt, Noel K. Maclaren, Svetlana Ten

Manuscripts, Articles, Book Chapters and Other Papers

INTRODUCTION: While the endogenous first-phase insulin response has disappeared by the time of diagnosis of type 1 diabetes mellitus (T1DM), anecdotal evidence suggests that these patients can continue to have a second-phase insulin response during the first 12 months after diagnosis. We hypothesized that patients who are started on continuous subcutaneous insulin infusion (CSII) at the time of diagnosis of T1DM would have a lower basal insulin requirement than the 40-60% usually expected.

METHODS: We analyzed 38 patients with T1DM, age 9.9 +/- 6.4 years, 71% male, who were started on CSII within the first month of diagnosis.

RESULTS: Average …

It Is More Than Just A Reproductive Healthcare Visit: Experiences From An Adolescent Medicine Clinic, Marlene B. Huff, Kimberly K. Mcclanahan, Heather A. Brown, Hatim A. Omar

Pediatrics Faculty Publications

The gynecologist may be the only physician that an adolescent depends on for primary and reproductive healthcare services. Because adolescent females often make personal healthcare decisions without the benefit of supportive parents/caregivers, it is imperative that the gynecologist understands the developmental issues encountered during this phase of life. The objective of this study is to identify cited complaints of adolescent females seeking reproductive care and, thus, provide gynecologists with needed information about the medical/mental health issues that may be encountered during routine reproductive care exams. The study group was adolescent females between the ages of 12 and 20 years old. …

Unusual Fibrosclerotic Lesion Of The Laryngotracheal Complex Presenting As Subglottic Stenosis., Douglas R. Johnston, Joseph M. Curry, Raphael Rubin, Marc R. Rosen

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

We present a case report that describes the pathology, presentation, and management complexities of an unusual, destructive fibrosclerotic lesion of the laryngotracheal complex. An otherwise healthy 21-year-old man presented with a 1-year history of progressive shortness of breath and stridor. The initial examination revealed a 3-cm, grade III subglottic stenosis. Nodular fibrosis of the strap muscles, laryngotracheal cartilages, and trachea was evident. Biopsies revealed dense peritracheal desmoplastic reaction with focal erosion of cartilage. However, features diagnostic for relapsing polychondritis, desmoid tumor, or orbital pseudotumor were absent. The disease progressed to involve severe stenosis and thickening of the trachea and main …
