An Improved Murine Femur Fracture Device For Bone Healing Studies, Joseph Marturano, Benjamin Cleveland, Melissa Bryne, Shannon O'Connell, John Wixted, Kristen Billiar

Kristen L. Billiar

Murine models are commonly used to investigate bone healing and test new treatments before human trials. Our objective was to design an improved murine femur fracture device and determine optimal mass and velocity settings for maximal likelihood of transverse fracture. Fracture reproducibility was maximized using an adjustable kinetic energy level, a novel mouse positioning system and an electromagnet striker release assembly. Sixty wild-type mice of 8-12-week-old male and female with a weight of 26.4+/-6.1g were subjected to an experimental postmortem fracture in the left and right femur (n=120) using variable kinetic energy inputs. A best-fit prediction equation for transverse fracture …

Participants and Method: Fifteen individuals (mean age = 54.6 years, SD = 9.6) with MS and Expanded Disability Status Scale (EDSS) scores ranging from 0-6.5 (mean = 4.2, SD = 2.3) participated in this randomized cross-over study. Following baseline measures of isometric quadricep and hamstring torque, subjects were exposed to …

Biomechanical Investigation Of A Novel Ratcheting Arthrodesis Nail, Jeremy Mccormick, Xinning Li, Douglas Weiss, Kristen Billiar, John Wixted

Kristen L. Billiar

BACKGROUND: Knee or tibiotalocalcaneal arthrodesis is a salvage procedure, often with unacceptable rates of nonunion. Basic science of fracture healing suggests that compression across a fusion site may decrease nonunion. A novel ratcheting arthrodesis nail designed to improve dynamic compression is mechanically tested in comparison to existing nails. METHODS: A novel ratcheting nail was designed and mechanically tested in comparison to a solid nail and a threaded nail using sawbones models (Pacific Research Laboratories, Inc.). Intramedullary nails (IM) were implanted with a load cell (Futek LTH 500) between fusion surfaces. Constructs were then placed into a servo-hydraulic test frame (Model …

Load Carriage Distance Run And Pushups Tests: No Body Mass Bias And Occupationally Relevant, Paul M. Vanderburgh, Nicholas S. Mickley, Philip A. Anloague, Kimber Lucius

Philip A. Anloague

Recent research has demonstrated body mass (M) bias in military physical fi tness tests favoring lighter, not just leaner, service members. Mathematical modeling predicts that a distance run carrying a backpack of 30 lbs would eliminate M-bias. The purpose of this study was to empirically test this prediction for the U.S. Army push-ups and 2-mile run tests. Two tests were performed for both events for each of 56 university Reserve Offi cer Training Corps male cadets: with (loaded) and without backpack (unloaded). Results indicated signifi cant M-bias in the unloaded and no M-bias in the loaded condition for both events. …

Gross Motor Development, Movement Abnormalities, And Early Identification Of Autism, Sally Ozonoff, Gregory S. Young, Stacy Goldring, Laura Greiss Hess, Andriana M. Herrera, Joel Steele, Suzanne Macari, Susan Hepburn, Sally J. Rogers

Laura Greiss Hess

Gross motor development (supine, prone, rolling, sitting, crawling, walking) and movement abnormalities were examined in the home videos of infants later diagnosed with autism (regression and no regression subgroups), developmental delays (DD), or typical development. Group differences in maturity were found for walking, prone, and supine, with the DD and Autism-No Regression groups both showing later developing motor maturity than typical children. The only statistically significant differences in movement abnormalities were in the DD group; the two autism groups did not differ from the typical group in rates of movement abnormalities or lack of protective responses. These findings do not …

Susan Morris

Background—Appropriate utilization of acute reperfusion therapy is not a national performance measure for ST-elevation myocardial infarction at this time, and the extent of its contemporary use among ideal patients is unknown.

Methods—From the National Registry of Myocardial Infarction, we identified 238,291 patients enrolled from June 1994 to May 2003 who were ideally suited for acute reperfusion therapy with fibrinolytic therapy or primary percutaneous coronary intervention. We determined rates of not receiving therapy across 3 time periods (June 1994–May 1997, June 1997–May 2000, June 2000– May 2003) and evaluated factors associated with underutilization.

Results—The proportion of ideal patients …

Motor Abilities Of Children Diagnosed With Fragile X Syndrome With And Without Autism, C. Zingerevich, L. G. Hess, K. Lemons Chitwood, S. W. Harris, D. Hessl, K. Cook, R. J. Hagerman

Laura Greiss Hess

Background—Previous studies suggested that children diagnosed with Fragile X Syndrome (FXS) often meet criteria for autism or PDD. This study describes the fine motor abilities of children diagnosed with FXS with and without autism spectrum disorder, and compares the motor scores of those groups controlling for cognitive level. Method—Forty-eight children, ages 12-76 months (SD=16) diagnosed with FXS were assessed with the Mullen Scales of Early Learning, and the Autism Diagnostic Observation Schedule (ADOS). Their parents were interviewed with the Autism Diagnostic Interview-Revised (ADI-R). We used a one-way analysis of variance (ANOVA) to determine if the fine motor scale of the …

Effects Of Sertraline Treatment For Young Children With Fxs, Laura Greiss Hess, Peter Mundy, Randi Hagerman

Laura Greiss Hess

Phenotypic manifestations for young children with fragile X syndrome (FXS) include: anxiety, sensory processing challenges, global language and communication deficits and intellectual and developmental disabilities. Many of these symptoms can be treated with medications, including selective serotonin reuptake inhibitors (SSRIs). However to date a clinical trial has not been conducted for children under five years old. This study investigated the following question: Are there group differences on developmental outcome measures for those children treated with sertraline compared to placebo?

Family Meanings, Contexts And Hopes Within A Clinical Trial, Laura Greis Hess, Cynthia Carter Ching, Randi Hagerman

Laura Greiss Hess

These qualitative analyses are a component of the clinical trial: “Effects of Sertraline Treatment for Young Children with FXS: Examination of Developmental Outcomes and Family Contexts.” We argue that inclusion of a sociocultural perspective within the context of a clinical trial affords consideration of: A dynamic view of development – simultaneous consideration of biological and sociocultural factors (Vygotsky, 1978). Application of a bioecological framework and consideration of ever changing nested settings and contexts over time (Bronfenbrenner, 2005)
