Objective: The primary aim of this research was to examine the temporal pattern of neuromuscular quadriceps deficits in both the involved and uninvolved limbs of patients assigned to the control group after anterior cruciate ligament reconstruction (ACLr), by assessing quadriceps strength, voluntary activation, and corticomotor excitability prior to surgery (baseline), three months after ACLr, and six months after ACLr. A secondary aim of this research was to determine whether quadriceps strength, voluntary activation, and/or corticomotor excitability assessed in patients prior to ACLr and/or at three months after surgery, is predictive of lower extremity postural control and/or self-reported function at six …

Retrospective Frames Of Disability: Themes Derived From Parents Of Children Who Grew Up With Congenital Disability, Sheryl L. Holt

Theses and Dissertations--Rehabilitation Sciences

Introduction: For children born with physical disabilities, the perspectives and actions of their parents prove significant to their childhood developmental outcomes clinically, educationally, socially, and with regard to community participation. The lived world and perceptions of parents who have children with disabilities however is not well investigated. This study sought to understand parents’ framing of theirs and their children’s disability experiences. Family systems together with family systems intervention models, and disability theory were used to provide structure to interview instrumentation and subsequent analysis. Child-centered and ecologic influences were also used to track the transformative processes over time that infuses parental …

Vocalization Subsystem Responses To A Temporarily Induced Unilateral Vocal Fold Paralysis, Daniel J. Croake

Theses and Dissertations--Rehabilitation Sciences

Healthy voicing is thought to be dependent on a dynamic balance of three interactive subsystems: respiration, phonation, and resonance. Theoretically, multiple patterns of subsystem interactions likely underlie healthy voice production; however surprisingly little quantitative data exists defining the nature of these subsystem production patterns and interactions across individuals.

The central aim of this study was to quantify the interactions of the vocalization subsystems in a non-perturbed and perturbed condition (induced unilateral vocal fold paralysis) in 10 vocally healthy participants. Respiratory inductance plethysmography, laryngeal aerodynamics, and acoustic formant data were used to measure the proportional contributions of, and changes to, the …

Prospective Assessment Of Return To Pre-Injured Levels Of Activity, Aaron D. Sciascia

Theses and Dissertations--Rehabilitation Sciences

Determining return to pre-injured levels of play following athletic injury can be challenging. The current practice of making decisions following rehabilitation as to whether or not a patient has returned to pre-injured levels of activity is potentially inaccurate because initial assessments of perceived physical capability are performed at a time of relative dysfunction or are based on patient recall. Since there is no true baseline of perceived and physical function prior to injury it is difficult to determine if an athlete has return to baseline or is simply better than they were at the time of injury. Therefore, it is …

A Biomechanically Based Observational Tennis Serve Analysis Method Can Be Used To Assess Serve Mechanics, Natalie Myers

Theses and Dissertations--Rehabilitation Sciences

Traditional sports science motion analysis techniques using three-dimensional (3D) kinematics have demonstrated that proper mechanics enhance serve performance and improper mechanics overload tissues resulting in injury. However 3D analysis is costly, time-consuming, and requires extensive knowledge of biomechanical properties and data analysis. Currently there are no simple, reliable, and valid observational methods for health care providers (HCP) and tennis professionals to evaluate tennis serve mechanics. Researchers investigating observational analyses have determined that superior reliability may be a result of specific operational definitions and the incorporation of educational training sessions on how to perform the analysis.

The first purpose of this …

Investigating The Efficacy Of Vocal Function Exercises In Improving Vocal Function In Adults Irradiated For Laryngeal Cancers: A Three Part Dissertation, Vrushali Angadi

Theses and Dissertations--Rehabilitation Sciences

Deterioration in voice quality following radiation therapy for the treatment of laryngeal cancers (LC) is well documented in literature. The majority of studies show that these voice problems are long term and in some cases permanent. Deterioration in voice quality, especially over a period of time could lead to significant communication difficulties in daily life or in some cases could even result in loss of profession. Despite the negative effects of radiation therapy on voice quality being well documented, few studies have focused on the efficacy of voice therapy in the irradiated LC population.

The purpose of this study was …

Two Sudden And Unexpected Deaths Of Patients With Schizophrenia Associated With Intramuscular Injections Of Antipsychotics And Practice Guidelines To Limit The Use Of High Doses Of Intramuscular Antipsychotics, Nasratullah Wahidi, Katie M. Johnson, Allen Brenzel, Jose De Leon

Psychiatry Faculty Publications

Intravenous haloperidol has been associated with torsades de pointes (TdP). These two sudden deaths were probable adverse drug reactions (ADRs) following intramuscular (IM) antipsychotics. The autopsies described lack of heart pathology and were highly compatible with the possibility of TdP in the absence of risk factors other than the accumulation of antipsychotics with a high serum peak after the last injection, leading to death within hours. The first case was a 27-year-old African-American male with schizophrenia but no medical issues. His death was probably caused by repeated IM haloperidol injections of 10 mg (totaling 35 mg in 2 days). The …

A Combination Of Two Rare Coronary Anomalies Makes It Even Rarer: Right Sided Single Coronary Artery With Dual Left Anterior Descending Artery, Aram Barbaryan, Theodore Addai, Monahar Kola, Muhammad Wajih Raqeem, Sergey Barsamyan, Aibek E. Mirrakhimov

Internal Medicine Faculty Publications

An 82-year-old female with history of hyperlipidemia and hypertension presented to the clinic with chief complaint of nonradiating chest tightness accompanied by exertional dyspnea. Cardiac catheterization showed the absence of left coronary system; the entire coronary system originated from the right aortic sinus as a common trunk which then gave off the right coronary artery and the left main coronary artery. Cardiac catheterization demonstrated also another rare coronary anomaly: dual left anterior descending artery. Patient underwent percutaneous coronary intervention and subsequent multidetector computed tomography angiography confirmed the above angiography findings. Patient was subsequently discharged home on double antiplatelet therapy with …

Telomerase Inhibition By Everolimus Suppresses Smooth Muscle Cell Proliferation And Neointima Formation Through Epigenetic Gene Silencing, Jun Aono, Ernesto Ruiz-Rodriguez, Hua Qing, Hannes M. Findeisen, Karrie L. Jones, Elizabeth B. Heywood, Dennis Bruemmer

Internal Medicine Faculty Publications

Proliferation of smooth muscle cells (SMCs) during neointima formation is prevented by drug-eluting stents. The replicative capacity of mammalian cells is enhanced by telomerase expression; however, the contribution of telomerase to the proliferative response underlying neointima formation and its potential role as a pharmacological target are unknown. The present study investigated the mechanisms underlying the mitogenic function of telomerase, and tested the hypothesis that everolimus, which is commonly used on drug-eluting stents, suppresses SMC proliferation by targeting telomerase. Inhibition of neointima formation by everolimus was lost in mice overexpressing telomerase reverse transcriptase (TERT), indicating that repression of telomerase confers the …

Acute Liver And Renal Failure: A Rare Adverse Effect Exclusive To Intravenous Form Of Amiodarone, Robin Paudel, Prerna Dogra, Saurav Suman, Saurav Acharya, Jyoti Matta

Internal Medicine Faculty Publications

Amiodarone is an antiarrhythmic drug which is highly effective against a wide spectrum of ventricular tachyarrhythmias making it irreplaceable in certain group of patients. We report an unusual case of acute liver and renal failure within 24 hours of initiation of intravenous (IV) amiodarone which resolved after stopping the medication. The mechanism of acute liver and renal toxicity is not clearly known but is believed to be secondary to amiodarone induced (relative) hypotension, idiosyncratic reaction to the drug, and toxicity of the vector that carries the medication, polysorbate-80. In this case review, we discuss the hyperacute drug toxicity caused by …

Overcoming Treatment Resistance In Heterogeneous Tumors, Nikhil Hebbar

Theses and Dissertations--Toxicology and Cancer Biology

Most primary tumors are heterogeneous and are often composed of therapy-sensitive and emerging therapy-resistant cancer cells. Rather unexpectedly, treatment of therapy-sensitive tumor cells in heterogeneous tumor microenvironments resulted in apoptosis of the therapy-resistant cancer cells. We identified a novel Par-4 amino-terminal fragment (PAF, which includes amino acids 1-131 of Par-4) that is produced and released by therapy-sensitive cancer cells following therapy-induced caspase-dependent cleavage of the tumor suppressor Par-4. PAF caused paracrine apoptosis in therapy-resistant cancer cells. Unlike Par-4-inducible apoptosis, which is dependent on the cell surface GRP78 receptor, PAF produced cancer-selective apoptosis independent of cell surface GRP78 function. Par-4 contains …

Incidence Of Non-Hodgkin's Lymphoma By Residential Proximity To Superfund Sites In Kentucky: A Multivariate Analysis, William Brent Webber

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Non-Hodgkin’s Lymphoma (NHL) is a category of cancers that arise from the lymphocytes of the immune system. The rates of NHL in the United States and Kentucky began to rise in the mid-20th Century, shortly after the manufacture, use, and disposal of numerous chemical substances began to increase during and after the Second World War. While the etiology of NHL is not fully known, there are several chemical substances for which evidence exists of a possible link between exposures and development of NHL and other cancers. Several of these substances are also present in sites within Kentucky designated by the …

Colorectal Cancer Prevention In The North Slope Borough Of Alaska Utilizing The Flu-Fit Intervention, Jennifer Jenkins

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

The intention of the Flu-FIT intervention is to increase colorectal cancer screening rates by combing two annual activities into one visit that doesn’t necessitate a doctors visit. The original study increased colorectal cancer screening rates by 14 percentage points and this program should be able to show similar results in the North Slope Borough of Alaska. The North Slope Borough has the highest incidence rate of colorectal cancer in the United States, and this proposed intervention could lead to a reduction in that rate by increasing screening and knowledge about colorectal cancer in the community.
