Cast-Saw Burns: Evaluation Of Skin, Cast, And Blade Temperatures Generated During Cast Removal, Franklin D. Shuler Md, Frank N. Grisafi

Orthopaedics

Background: The use of an oscillating saw for cast removal creates a potential for iatrogenic injury and patient discomfort. Burns and abrasions can occur from the heat created by frictional forces and direct blade contact. With use of a cadaver model system, skin temperature measurements were recorded during cast removal with an oscillating saw.

Methods: Casts of uniform thickness were applied to cadavers equilibrated to body temperature. The casts were removed by a single individual while simultaneously measuring temperatures at the skin-padding interface, cast-padding interface, and the blade. Variables tested include two removal techniques, two casting materials (fiberglass and plaster), …

Physician’S Ability To Manually Detect Isolated Elevation In Leg Intracompartmental Pressure., Franklin D. Shuler Md, Matthew J. Dietz

Orthopaedics

Background: Serial physical examination is recommended for patients for whom there is a high index of suspicion for compartment syndrome. This examination is more difficult when performed on an obtunded patient and relies on the sensitivity of manual palpation to detect compartment firmness—a direct manifestation of increased intracompartmental pressure. This study was performed to establish the sensitivity of manual palpation for detecting critical pressure elevations in the leg compartments most frequently involved in clinical compartment syndrome.

Methods: Reproducible, sustained elevation of intracompartmental pressure was established in fresh cadaver leg specimens. Pressures tested included 20 and 40 mm Hg (negative controls) …

Summary of Background Data. NDI is commonly used for measuring neck-related disability in patients with neck pain; but it does not offer to assess …

Acetaminophen Improves Protein Translational Signaling In Aged Skeletal Muscle, Miaozong Wu, Hua Liu, Jacqueline Fannin, Anjaiah Katta, Yeling Wang, Ravi Kumar Arvapalli, Satyanarayana Paturi, Sunil K. Karkala, Kevin M. Rice, Eric R. Blough

MIIR Faculty Research

Background: Age-related muscle atrophy is characterized by increased oxidative stress, diminished Akt enzymatic function, and reduced phosphorylation of the mammalian target of rapamycin (mTOR), which can be attenuated by chronic acetaminophen ingestion. Here we hypothesize that age-related impairments in Akt/ mTOR function are associated with reduced protein translational signaling, and that these changes, if present, can be attenuated by acetaminophen treatment.

Results: Compared to 6- and 27-month old animals, the expression of the mTOR-complex proteins raptor and GbL and the phosphorylation of tuberin/TSC2 (Thr1462) were reduced in the soleus muscles of very aged rats (33 months old). These changes in …

Gorman, Ellen Wruble Hakim, Wendy Johnson, Sujoy Bose, Katherine S. Harris, Molly H. Crist, Karen Holtgrefe, Jennifer M. Ryan, Michael S. Simpson, Jean Bryan Coe

Physical Therapy Faculty Research

Background and Purpose. Acute care physical therapists have experienced the effects of dramatic changes in health care reimbursement systems and population demographics. Acute care hospitals now serve a patient population of much older, chronically ill patients who are hospitalized for shorter periods of time in a practice environment in which physical therapy staffing resources are often inadequate. The purposes of this study were to document common experiences in the practice of acute care physical therapy and to identify differences in the perceptions of physical therapists with varying levels of experience and in various sizes of acute care facilities.

Residence In A Distressed County In Appalachia As A Risk Factor For Diabetes, Behavioral Risk Factor Surveillance System, 2006-2007, Lawrence Barker, Richard Crespo, Robert B. Gerzoff, Sharon Denham, Molly Shrewsberry, Darrlyn Cornelius-Averhart

Family and Community Health

Introduction

We compared the risk of diabetes for residents of Appalachian counties to that of residents of non-Appalachian counties after controlling for selected risk factors in states containing at least 1 Appalachian county.

Methods

We combined Behavioral Risk Factor Surveillance System data from 2006 and 2007 and conducted a logistic regression analysis, with self-reported diabetes as the dependent variable. We considered county of residence (5 classifications for Appalachian counties, based on economic development, and 1 for non-Appalachian counties), age, sex, race/ethnicity, education, household income, smoking status, physical activity level, and obesity to be independent variables. The classification “distressed” refers to …

Radially Aligned, Electrospun Nanofibers As Dural Substitutes For Wound Closure And Tissue Regeneration Applications, Jingwei Xie, Matthew R. Macewan, Wilson Z. Ray, Wenying Liu, Daku Y. Siewe, Younan Xia

MIIR Faculty Research

This paper reports the fabrication of scaffolds consisting of radially aligned poly(ε-caprolactone) nanofibers by utilizing a collector composed of a central point electrode and a peripheral ring electrode. This novel class of scaffolds was able to present nanoscale topographic cues to cultured cells, directing and enhancing their migration from the periphery to the center. We also established that such scaffolds could induce faster cellular migration and population than nonwoven mats consisting of random nanofibers. Dural fibroblast cells cultured on these two types of scaffolds were found to express type I collagen, the main extracellular matrix component in dural mater. The …

The Development Of Attribute Dominance In The Knowledge Base, Marc A. Lindberg Ph.D.

Psychology Faculty Research

Two cuing, free-recall studies were conducted to test Bach and Underwood's (1970) hypothesis that acoustic encoding is dominant among second graders and semantic encoding is dominant among sixth graders. When retrieval cues were presented with to-be-remembered items at both input and output (Experiment 1), and when cues were presented only at output (Experiment 2), semantic cues were more efficient in elevating recall than were acoustic cues for both second and sixth graders. When these and other results generally found using recognition, sorting, incidental learning, and free-recall experimental designs are compared, it seems plausible that item presentation and memory-testing formats interact …

Prolongation Of Carrageenan-Induced Inflammation In Human Colonic Epithelial Cells By Activation Of An Nfκb-Bcl10 Loop, Alip Borthakur, Sumit Bhattacharyya, Arivarasu N. Anbazhagan, Anoop Kumar, Pradeep K. Dudeja, Joanne K. Tobacman

Clinical & Translational Sciences

Carrageenan, a sulfated polysaccharide that is widely used as a food additive, induces inflammatory responses in animal models and human cells. The carrageenan-induced inflammatory cascades involve tolllike receptor (TLR)4- and B-cell leukemia/lymphoma (BCL)10-dependent activation of NF-κB, leading to increased IL-8 production. Translocations involving BCL10 in the mucosa-associated lymphoid tissue (MALT) lymphomas are associated with constitutive activation of NF-κB. This report presents a mechanism by which carrageenan exposure leads to prolonged activation of both BCL10 and NF-κB in human colonic epithelial cells. Study findings demonstrate that nuclear RelA and RelB bind to an NF-κB binding motif in the BCL10 promoter in …

Inhibition Of Proliferation And Induction Of Apoptosis In Multiple Myeloma Cell Lines By Cd137 Ligand Signaling, Charles A. Gullo Phd, Liang Kai Koh, Wan Lu Pang, Kian Tong Ho, Shi Hao Tan, Herbert Schwarz

Biochemistry and Microbiology

Background

Multiple myeloma (MM) is a malignancy of terminally-differentiated plasma cells, and the second most prevalent blood cancer. At present there is no cure for MM, and the average prognosis is only three to five years. Current treatments such as chemotherapy are able to prolong a patient's life but rarely prevent relapse of the disease. Even hematopoietic stem cell transplants and novel drug combinations are often not curative, underscoring the need for a continued search for novel therapeutics. CD137 and its ligand are members of the Tumor Necrosis Factor (TNF) receptor and TNF superfamilies, respectively. Since CD137 ligand cross-linking enhances …

Application Of Poly(Amidoamine) Dendrimers For Use In Bionanomotor Systems, Madhukar Babu Kolli, B. Scott Day, Hideyo Takatsuki, Siva Krishna Nalabotu, Kevin M. Rice, Kazuhiro Kohama, Murali K. Gadde, Anjaiah Katta, Eric R. Blough

MIIR Faculty Research

The study and utilization of bionanomotors represents a rapid and progressing field of nanobiotechnology. Here, we demonstrate that poly(amidoamine) (PAMAM) dendrimers are capable of supporting heavy meromyosin dependent actin motility of similar quality to that observed using nitrocellulose, and that microcontact printing of PAMAM dendrimers can be exploited to produce tracks of active myosin motors leading to the restricted motion of actin filaments across a patterned surface. These data suggest that the use of dendrimer surfaces will increase the applicability of using protein biomolecular motors for nanotechnological applications.

Capsaicin Displays Anti-Proliferative Activity Against Human Small Cell Lung Cancer In Cell Culture And Nude Mice Models Via The E2f Pathway, Kathleen C. Brown, Theodore R. Witte, W. Elaine Hardman, Haitao Luo, Yi C. Chen, A. Betts Carpenter, Jamie K. Lau, Piyali Dasgupta

Biochemistry and Microbiology

Background: Small cell lung cancer (SCLC) is characterized by rapid progression and low survival rates. Therefore, novel therapeutic agents are urgently needed for this disease. Capsaicin, the active ingredient of chilli peppers, displays antiproliferative activity in prostate and epidermoid cancer in vitro. However, the anti-proliferative activity of capsaicin has not been studied in human SCLCs. The present manuscript fills this void of knowledge and explores the anti-proliferative effect of capsaicin in SCLC in vitro and in vivo.

Methodology/Principal Findings: BrdU assays and PCNA ELISAs showed that capsaicin displays robust anti-proliferative activity in four human SCLC cell lines. Furthermore, capsaicin potently …

Investigating The Role Of P311 In The Hypertrophic Scar, Jianglin Tan, Xu Peng, Gaoxing Luo, Bing Ma, Chuan Cao, Weifeng He, Shunzong Yuan, Shirong Li, John A. Wilkins, Jun Wu

MIIR Faculty Research

The mechanisms of hypertrophic scar formation are not fully understood. We previously screened the differentially expressed genes of human hypertrophic scar tissue and identified P311 gene as upregulated. As the activities of P311 in human fibroblast function are unknown, we examined the distribution of it and the effects of forced expression or silencing of expression of P311. P311 expression was detected in fibroblast-like cells from the hypertrophic scar of burn injury patients but not in peripheral blood mononuclear cells, bone marrow mesenchymal stem cells, epidermal cells or normal skin dermal cells. Transfection of fibroblasts with P311 gene stimulated the expression …

Is Uncompensated Care Affecting Quality Assurance Of Rural Hospitals?, Doohee Lee, Chris Dixon, Paul Kruszynski, Alberto Coustasse

Management Faculty Research

Healthcare disparities in rural areas remain significant in the U.S. healthcare industry. Uncompensated care makes healthcare disparities in rural areas worse and rural hospitals are unfavorably positioned to compete with urban hospitals in the economic downturn marketplace. How uncompensated care affects quality care among rural hospitals has been lightly investigated. As many rural residents experience difficulty accessing high quality care and the importance of establishing quality care practice standards in a rural setting, we conducted a systematic literature review to identify some quality care barriers and opportunities, suggested strategies to strengthen the position of rural hospitals in response to uncompensated …

Electronic Medical Records: Is It Working In Long Term Health Care?, Krista Phillips, Chris Wheeler, Josh Campbell, Alberto Coustasse

Management Faculty Research

Long-term care (LTC) facilities possess unique characteristics in terms of implementation and utilization of electronic medical records (EMRs). The focus of LTC is on a population requiring care encompassing all aspects associated with quality of life rather than simply acute treatment. Because this focus is of a larger scale than traditional medical facilities, the priorities in the implementation and utilization of EMRs are higher in accessing patient history information. The purpose of this study was to determine the EMR utilization in the chronic care settings. In conclusion, the literature review performed does not support the fact that EMRs are currently …

Management Of Kawasaki Disease In Texas: Policy Implications, Alberto Coustasse, Doohee Lee, Cody Arvidson, Julius J. Larry Iii, Witold Migala

Management Faculty Research

Kawasaki Disease (KD) is the leading cause of acquired cardiovascular disease among children, but KD has received little attention on its management from a policy perspective. The core objective of this paper is to review the literature, identify problems related to KD, and evaluate and offer some policy alternatives to effectively prevent and treat KD epidemiologically in Texas. Policy options suggested in this paper include, among others, (1) establishing a mandatory national KD registry system (along with active surveillance), (2) introducing sentinel providers, (3) requiring mandatory reporting of KD by hospitals, and (4) sponsoring policy KD research and practice.

Rbc And Wbc Fatty Acid Composition Following Consumption Of An Omega 3 Supplement: Lessons For Future Clinical Trials, Theodore R. Witte, Alexander J. Salazar, Oscar F. Ballester, W. Elaine Hardman

Biochemistry and Microbiology

Background: Results from increasing numbers of in vitro and in vivo studies have demonstrated that omega 3 fatty acids incorporated in cell culture media or in the diet of the animals can suppress the growth of cancers. When human clinical trials are initiated to determine the ability of omega 3 fatty acids to alter growth or response to chemotherapeutic interventions of cancers, it will be essential to determine the omega 3 intake of individuals in the trial to determine compliance with consumption of the supplement and to correlate with endpoints of efficacy. We wondered if the fatty acid composition of …

Maternal Consumption Of Canola Oil Suppressed Mammary Gland Tumorigenesis In C3(1) Tag Mice Offspring, Gabriela Ion, Juliana A. Akinsete, W. Elaine Hardman

Biochemistry and Microbiology

Background: Maternal consumption of a diet high in omega 6 polyunsaturated fats (n-6 PUFA) has been shown to increase risk whereas a diet high in omega 3 polyunsaturated fats (n-3 PUFA) from fish oil has been shown to decrease risk for mammary gland cancer in female offspring of rats. The aim of this study was to determine whether increasing n-3 PUFA and reducing n-6 PUFA by using canola oil instead of corn oil in the maternal diet might reduce the risk for breast cancer in female offspring.

Methods: Female SV 129 mice were divided into two groups and placed on …

Understanding Autonomous Practice, Tamara Gravano, Greg Hartley, Heather Mattingly, Joseph Libera, Sabrina Camilo, Jason Hardage

Physical Therapy Faculty Research

What is autonomous practice? As one of the elements of Vision 2020, au­tonomous practice is one whose mean­ing may not always be readily under­stood. The confusion can stem from the meaning of autonomy, which is sometimes misinterpreted to mean that the physical therapist (PT) practices in a vacuum, without coordinating and com­municating with other health care pro­viders. Nothing could be further from the truth. In fact, many PTs might be surprised to learn that they already prac­tice autonomously.

Results indicated that implementing the RFID model for tracking drugs at the item level in the pharmaceutical supply chain has potential to alleviate the scope of …

"A Cage Of Ovulating Females" : Mary Breckinridge And The Politics Of Contraception In Rural Appalachia, Dana Allen Johnson

Theses, Dissertations and Capstones

Mary Breckinridge and the Frontier Nursing Service have been the focus of intense scholarly effort over the last twenty years. Scholarship on Mary Breckinridge has centered on her healthcare reform work in Appalachia and its effects on the local residents and culture. This thesis examines the oral contraceptive trial that the FNS performed in Leslie County in the late 1950s and early 1960s. Although Breckinridge and the FNS maintained a restrictive contraceptive stance, they paradoxically permitted the contraceptive trial to be conducted on their patients in Leslie County. The decision to participate in the contraceptive trial resulted from a complex …

Antibiotic Sensitivity Patterns Of Hospital-Acquired And Community-Acquired Methicillin Resistant Staphylococcus Aureus, Iyad Kaddora

Theses, Dissertations and Capstones

Staphylococcus aureus is one of the most dangerous human pathogens. An intensive effort to control resistant staphylococci, especially methicillin resistant Staphylococcus aureus (MRSA), is vital as it is the most common cause of hospitalacquired infections. During the one year study period, a total of 35 MRSA isolates were collected. Fifteen isolates were identified as hospital-acquired (HA) infections, and 20 isolates were determined to be community acquired (CA). All 15 (100%) HA-MRSA strains were resistant to clindamycin and to erythromycin. Thirteen isolates (87%) were resistant to ciprofloxacin and levofloxacin, and 12 (80%) were resistant to moxifloxacin. Of the 20 CA-MRSA isolates, …

Treatment Strategies In Acute Myelogenous Leukemia : Investigating Hsp90 And P53 As Targets, Jennifer M. Napper

Theses, Dissertations and Capstones

Acute myelogenous leukemia (AML) is the deadliest of the lymphatic and bone marrow cancers. Patients diagnosed with AML have a five year survival rate of 23.4%. AML is characterized by an accumulation of undifferentiated and functionless myeloid precursors in the bone marrow and blood. Heat shock protein 90 (Hsp90) inhibitors, such as 17-AAG, an analog of geldanamycin (GM), are currently undergoing phase I, and II and III clinical trials for various cancers with mixed results. I found distinct responses to 17-AAG treatment among the AML cell lines tested. I also discovered two mutant TP53 alleles in Kasumi-3 cells, an AML …

Age- And Sex-Associated Changes In Mrna Expression Of Neurodegenerative Disorder-Related Molecules In The Hippocampus And Cerebellum Of Rat Brain, Srinivasarao Thulluri

Theses, Dissertations and Capstones

Age-associated oxidative stress is involved in neurodegenerative disorders such as Alzheimer’s and Parkinson’s diseases, and sex-associated differences may also affect the risk for these neurodegenerative diseases. We compared the effects of aging and sex on the mRNA expression of five molecules that are closely related to oxidative stress, along with Alzheimer’s and Parkinson’s diseases in the hippocampus of both male and female Fischer 344xBrown Norway (F344BN) rats. The reverse transcription polymerase chain reaction was used to determine the mRNA expression level of superoxide dismutase 2 (SOD2), heme oxygenase 1 (HO1), amyloid precursor protein (APP), -site APP-cleaving enzyme 1 (BACE1), and …

Genetic And Environmental Factors Suggest That Dietary Fatty Acid Content, Lipid Metabolism, And Bone Properties Are Key Regulators Of Myeloid Progenitor Cell Frequency, Melinda E. Varney

Theses, Dissertations and Capstones

Acute myelogenous leukemia (AML) and its precursors are the result of the dysregulation of hematopoiesis. Hematopoiesis proceeds in a stepwise manner, beginning with hematopoietic stem cells, continuing to develop into various stages of progenitor cells, and finally becoming fully functional blood cells. As this process goes awry, immature, functionless cells of the myeloid lineage proliferate out of control. Discerning how myeloid progenitor frequency is regulated allows for a better understanding of how the process may lose control. Hematopoiesis has been shown to depend on genetic and environmental factors. In this work, I have added to this knowledge base by providing …

Modeling Super-Spreading Events For Sars, Thembinkosi P. Mkhatshwa

Theses, Dissertations and Capstones

One of the intriguing characteristics of the 2003 severe acute respiratory syndrome (SARS) epidemics was the occurrence of super spreading events (SSEs). Super-spreading events for a specific infectious disease occur when infected individuals infect more than the average number of secondary cases. The understanding of these SSEs is critical to under- standing the spread of SARS. In this thesis, we present a modification of the basic SIR (Susceptible - Infected - Removed) disease model, an SIPR (Susceptible - Regular Infected - Super-spreader - Removed) model, which captures the effect of the SSEs.

An Initial Investigation Of The Applicability Of The Dreyfus Skill Acquisition Model To The Professional Development Of Nurse Educators, Lisa Ramsburg

Theses, Dissertations and Capstones

Little is known about the skill and knowledge acquisition of nurses in the educator role. This investigation represents an attempt to design and validate a skill acquisition model for the nurse educator role. While nurse educators often have strong clinical backgrounds, they face a significant role transition as nurse educators. Dreyfus and Dreyfus provided a model for studying skill acquisition in several fields and Benner applied the model to clinical nursing. To investigate skill acquisition among nurse educators, the Dreyfus Model of Skill Acquisition along with the National League for Nursing (NLN) Nurse Educator Competencies provided a framework for the …

The Medicalization Of Hyperactivity And Inattentiveness : A Social History And Theoretical Perspectives On Adhd, Justin Douglas Brock

Theses, Dissertations and Capstones

This study investigates the rise of the Attention-Deficit/Hyperactivity Disorder diagnosis. It approaches the topic from a medicalization perspective and frames it under the therapeutic state as proposed by Nicholas Kittrie in 1971. It asks three questions: how has society, and particularly, the medical community changed to allow the medicalization of hyperactivity and social control of active children? How has the continuing diagnosis of hyperactivity in children expanded to include attention deficit hyperactivity disorder in both children and adults? And what forces are behind the continuously inclusive diagnosis and why? In an attempt to answer these questions the history of the …
