Neurocognitive Patterns, Symptom Clusters, And Premorbid Factors That Predict Protracted Recovery From Concussion In Females, Sarah Pulaski

PCOM Psychology Dissertations

Concussion is an increasingly diagnosed injury that affects individuals of all ages. Although the underlying cause is unknown, research has demonstrated that females who sustain a concussion experience longer recoveries. Existing research has documented a relationship between age, gender, post-concussive headache and mental health conditions, and recovery; however, limited research has investigated the relationship between premorbid clinical variables and recovery. Research on post-injury neurocognitive declines and recovery has also demonstrated varied findings. Moreover, dizziness has been identified as significantly predictive of prolonged recovery, but no studies have investigated the effect of premorbid headache conditions on the development of dizziness. The …

Insulin Resistance And Muscle Insulin Receptor Substrate-1 Serine Hyperphosphorylation, Charles A. Stuart, Mary E. A. Howell, Brian M. Cartwright, Melanie P. Mccurry, Michelle L. Lee, Michael W. Ramsey, Michael H. Stone

ETSU Faculty Works

Insulin resistance in metabolic syndrome subjects is profound in spite of muscle insulin receptor and insulin-responsive glucose transporter (GLUT4) expression being nearly normal. Insulin receptor tyrosine kinase phosphorylation of insulin receptor substrate-1 (IRS-1) at Tyr896 is a necessary step in insulin stimulation of translocation of GLUT4 to the cell surface. Serine phosphorylation of IRS-1 by some kinases diminishes insulin action in mice. We evaluated the phosphorylation status of muscle IRS-1 in 33 subjects with the metabolic syndrome and seventeen lean controls. Each underwent euglycemic insulin clamps and a thigh muscle biopsy before and after 8 weeks of either strength or …

Designing A Mechanical Linkage Capable Of Decreasing Force Transfer From The Facemask To The Protective Helmet When Loading Occurs, Levi Hansen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction

Sports that involve extensive personal contact have a high incidence of injury. The introduction of regulations mandating the use of personal protective equipment in these sports is the most common injury control strategy (Marshall et al., 2002). Negligible attention has been paid to the mechanical linkage between the facemask and helmet as a means of reducing force transfer from the facemask, through the helmet, and to the head and or neck of the athlete.

Methods

A novel prototype mechanical linkage of reasonable simplicity that provides 360° of freedom in motion capable of decreasing force transfer from the facemask to …

Sports Related Traumatic Brain Injuries, Ky Parrott

Nursing Student Class Projects (Formerly MSN)

Traumatic Brain Injuries (TBI) are the leading cause of long-term disability and injury death in the United States of America (Dash, Oh, Santiago, & Wade, 2012, p. 108). It is estimated that approximately 75% of all TBI’s are sports related. Recently, sports related TBI’s have received increased awareness due to the $765 million settlement between 18,000 retired football players who suffer from long-term concussive injuries and the National Football Association (NFL) (Mason, 2013, p. 267). Education regarding the pathophysiology of TBI’s is beneficial to understanding what changes the brain is enduring and why it is important to protect the brain, …

Blood-Based Biomarkers For Traumatic Brain Injury: Evaluation Of Research Approaches, Available Methods And Potential Utility From The Clinician And Clinical Laboratory Perspectives, Frederick G. Strathmann, Stefanie Podlog (Nee Schulte), Kyle Goerl, David J. Petron

Athletic Training Collection

Blood-based biomarkers for traumatic brain injury (TBI) have been investigated and proposed for decades, yet the current clinical assessment of TBI is largely based on clinical symptoms that can vary widely amongst patients, and have significant overlap with unrelated disease states. A careful review of current treatment guidelines for TBI further highlights the potential utility of a blood-based TBI biomarker panel in augmenting clinical decision making. Numerous expert reviews on blood-based TBI biomarkers have been published but a close look at the methods used and the astonishing paucity of validation and quality control data has not been undertaken from the …

Refeeding Syndrome In A Young Girl With Anorexia Nervosa., Om Parkash, Adil Ayub, Shahab Abid

Department of Medicine

We report the case of a 20-year-old anorexic girl (BMI=12.9), who was misdiagnosed the first time and developed severe electrolyte imbalances due to lack of awareness about refeeding syndrome. Few cases of RS have been reported in literature and protocols have been suggested for prevention and management of this syndrome, including the awareness of circumstances in which it is most likely to develop, refeeding slowly and building-up micronutrient content over several days. Improved awareness and understanding of refeeding syndrome along with a well-coordinated plan are vital in delivering safe and effective nutritional rehabilitation. We suggest a slow and gradual increase …

Interleukin-1 Receptor Antagonist Modulates Inflammation And Scarring After Ligament Injury, Connie S. Chamberlain, Ellen M. Leiferman, Kayt E. Frisch, Sarah E. Duenwald-Kuehl, Stacey L. Brickson, William L. Murphy, Georffrey S. Baer, Ray Vanderby

Faculty Publications - Biomedical, Mechanical, and Civil Engineering

Ligaments have limited regenerative potential and as a consequence, repair is protracted and results in a mechanically inferior tissue more scar-like than native ligament. We previously reported that a single injection of interleukin-1 receptor antagonist (IL-1Ra) delivered at the time of injury, decreased the number of M2 macrophage-associated inflammatory cytokines. Based on these results, we hypothesized that IL-1Ra administered after injury and closer to peak inflammation (as would occur clinically), would more effectively decrease inflammation and thereby improve healing. Since IL-1Ra has a short half-life, we also investigated the effect of multiple injections. The objective of this study was to …

The Influence Of Partial And Full Thickness Tears On Infraspinatus Tendon Strain Patterns, Kayt E. Frisch, David Marcu, Geoffrey S. Baer, Darryl G. Thelen, Ray Vanderby

Faculty Publications - Biomedical, Mechanical, and Civil Engineering

Tears on the bursal and articular sides of the rotator cuff tendons are known to behave differently and strain is thought to play a role in this difference. This study investigates the effect of tear location on the changes in three strain measurements (grip-to-grip, insertion, and mid-substance tissue) in a sheep infraspinatus tendon model during axial loading. We introduced a 14mm wide defect near the insertion from either the articular or bursal side of the tendon to three depths (3 mm, 7mm & full) progressively. For each condition, tendons were sinusoidally stretched (4% at 0.5 Hz) while insertion and midsubstance …

Influence Of Tendon Tears On Ultrasound Echo Intensity In Response To Loading, Kayt E. Frisch, David Marcu, Geoffrey S. Baer, Darryl G. Thelen, Ray Vanderby

Faculty Publications - Biomedical, Mechanical, and Civil Engineering

Acoustoelastic (AE) ultrasound image analysis is a promising non-invasive approach that uses load-dependent echo intensity changes to characterize stiffness of tendinous tissue. The purpose of this study was to investigate whether AE can detect localized changes in tendon stiffness due to partial and full-thickness tendon tears. Ovine infraspinatus tendons with different levels of damage (Intact, 33%, 66% and full thickness cuts initiated on the articular and bursal sides) were cyclically loaded in a mechanical testing system while cine ultrasound images were recorded. The load-induced changes in echo intensity on the bursal and articular side of the tendon were determined. Consistent …
