Characteristics Of Athletic Trainers That Are Satisfied And Dissatisfied With Their Compensation, K Ef Mair, J P. Young, L E. Eberman

Clinical Practice in Athletic Training

Introduction: Job satisfaction among athletic trainers (ATs), particularly in relation to compensation, is a critical factor influencing retention and career fulfillment. Examining the factors linked to earnings satisfaction may offer insight into how workplace conditions can be improved to better support ATs. The purpose of our study was to investigate the attributes that distinguish ATs content with their compensation from those who are dissatisfied. Methods: We used a cross-sectional, web-based survey to gather AT compensation data, of which 1,887 participants responded to a question regarding their satisfaction with compensation. Respondents were divided into two groups based on their satisfaction with …

Enhancing Clinic Efficiency: A Quality Improvement Initiative For Postoperative Patient Care In An Outpatient Orthopedic Physician Practice Setting, D Stepan, T Jp Greffly, R M. Williams

Clinical Practice in Athletic Training

Introduction: Following orthopedic surgery, patient post-operative (post-op) visits are deemed global surgical observations where day 00 to day 90 are appointments that cannot be billed. Patients are typically seen 3 times during this global period. Thus, the outpatient clinic needs to have non-billable time slots each day for these patients. The current scheduling model double books patients every 15 minutes, with the physician being the primary provider seeing patients for post-op visits. Therefore, the clinic has demonstrated inefficiencies with scheduling these patients while having sufficient appointments available for billable patients. This quality improvement initiative aimed to decrease post-op patient visits …

Bayesian Population Pharmacokinetic Modeling Of Ondansetron For Neonatal Opioid Withdrawal Syndrome, Kevin Lam, John Mondick, Gary Peltz, Manhong Wu, Walter Kraft

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

Ondansetron is an anti-emetic 5-HT3 receptor antagonist being investigated for treating neonatal opioid withdrawal syndrome (NOWS). Sparse PK data were analyzed from a multicenter, double-blind clinical trial with 98 mother/neonate dyads. Pregnant women with opioid use disorder were randomized to receive either placebo or ondansetron 8 mg intravenously within 4 h of delivery. Neonates born to mothers who were randomized to ondansetron received 0.07 mg/kg orally once every 24 h for up to five doses. Using current PK data, model parameters from a two-compartmental structural model from the literature (i.e., a priori model) were updated with the Metropolis-Hastings Markov-chain Monte …

The C-Terminal Phdvc5hch Tandem Domain Of Nsd2 Is A Combinatorial Reader Of Modified H3k4 And Tri-Methylated H3k27 That Regulates Transcription Of Cell Adhesion Genes In Multiple Myeloma, Andrea Berardi, Charlotte Leonie Kaestner, Michela Ghitti, Giacomo Quilici, Paolo Cocomazzi, Jianping Li, Federico Ballabio, Chiara Zucchelli, Stefan Knapp, Jonathan Licht, Giovanna Musco

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

Histone methyltransferase NSD2 (MMSET) overexpression in multiple myeloma (MM) patients plays an important role in the development of this disease subtype. Through the expansion of transcriptional activating H3K36me2 and the suppression of repressive H3K27me3 marks, NSD2 activates an aberrant set of genes that contribute to myeloma growth, adhesive and invasive activities. NSD2 transcriptional activity also depends on its non-catalytic domains, which facilitate its recruitment to chromatin through histone binding. In this study, using NMR, ITC and molecular dynamics simulations, we show that the tandem PHD domain of NSD2 (PHDVC5HCHNSD2) is a combinatorial reader of unmodified histone H3K4 and tri-methylated H3K27 …

Motion Artifacts (Ma) At-Rest In Measured Arterial Pulse Signals: Time-Varying Amplitude In Each Harmonic And Non-Flat Harmonic-Ma Coupled Baseline, Md Mahfuzur Rahman, Mamun Hasan, Zhili Hao

Mechanical & Aerospace Engineering Faculty Publications

Motion artifacts (MA) cause great variability in a measured arterial pulse signal, and treatment of MA solely as a baseline drift (BD) fails to eliminate its effect on the measured signal. This paper presents a study on the effect of MA at rest (< 0.7 Hz) on measured arterial pulse signals using a microfluidic-based tactile sensor. By taking full account of the dynamic behavior of the transmission path from the true pulse signal in an artery to a measured pulse signal at the sensor, the tissue-contact-sensor (TCS) stack, an analytical model of MA in a measured pulse signal is developed. In this model, the TCS stack is treated as a 1DOF system for its dynamic behavior; MA is quantified as the displacement (i.e., BD) and time-varying system parameters (TVSP) of the TCS stack. The mathematical expression of MA in a measured pulse signal reveals that while BD remains as low-frequency additive noise, TVSP causes time-varying harmonics in a measured pulse signal. Further time-frequency analysis (TFA) of measured pulse signals validates the existence of TVSP and, for the first time, reveals its effect on a measured pulse signal: time-varying amplitude in each harmonic and non-flat harmonic-MA-coupled baseline.

A Non-Toxic Analgesic Elicits Cell-Specific Genomic And Epigenomic Modulation By Targeting The Pag Brain Region, Hernan A. Bazan, Brian L. Giles, Surjyadipta Bhattacharjee, Scott Edwards, Nicolas G. Bazan

School of Medicine Faculty Publications

Acetaminophen (ApAP) is widely used for pain management, but overuse or overdose leads to hepatotoxicity, making it the leading cause of acute liver failure globally. There is an urgent need for safer pain medications, as other non-opioid analgesics like non-steroidal anti-inflammatory drugs (NSAIDs) are nephrotoxic. We have identified SRP-001 as a safer, non-hepatotoxic, novel analgesic that overcomes ApAP's limitations by avoiding NAPQI formation and preserving hepatic tight junctions. Using coupled RNA and ATAC sequencing, from the periaqueductal gray (PAG) midbrain region, we compared the genetic and epigenetic signatures of SRP-001 and ApAP treatments following complete Freund's adjuvant (CFA)-induced inflammatory pain …

Explorations Of Dna-Single-Walled Carbon Nanotube Interactions To Develop Multiplexed Molecularly Specific Biosensors For Inflammation, Amelia K. Ryan

Dissertations and Theses

Inflammatory cytokines such as interleukin-6 (IL-6) and interleukin-12 (IL-12) are central regulators of immune signaling and key biomarkers of disease, yet existing assays for their detection remain slow, invasive, and lack multiplexing ability. This dissertation advances the development of single-walled carbon nanotube (SWCNT) optical nanosensors capable of real-time, multiplexed, and molecularly specific cytokine detection through innovative use of single-stranded DNA (ssDNA) interfaces.

First, an IL-6-specific DNA aptamer was employed as both a dispersing agent and recognition probe for SWCNT fluorescence sensing. Sequence modifications, including anchor domains, truncations, and thermally induced refolding, were systematically tested to optimize sensitivity and selectivity. The …

Effects Of High-Frequency Repetitive Transcranial Magnetic Stimulation On Impulse Control Disorders In Patients With Parkinson’S Disease On Dopamine Replacement Therapy, Katherine Muksuris

Graduate Theses, Dissertations, and Problem Reports (ETD)

Parkinson’s Disease (PD) is a debilitating neurodegenerative disorder that causes motor deficits, cognitive impairment, and depression. The mainstay treatment for motor symptoms is dopamine replacement therapy (DRT). DRT takes the form of levodopa or dopamine receptor agonists (DAs) and can be associated with impulse control disorders (ICDs). Currently, the approach to mitigating these side effects is to decrease or stop DRT, which may cause motor symptoms to return, making the management of the disorder more difficult. Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive neuromodulation treatment for multiple disorders, including its approved use for smoking cessation. It has also shown …

Multi-Organ Gene Expression Analysis And Network Modeling Reveal Regulatory Control Cascades During The Development Of Hypertension In Female Spontaneously Hypertensive Rat, Eden Hornung, Sirisha Achanta, Alison Moss, James S. Schwaber, Rajanikanth Vadigepalli

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Hypertension is a multifactorial disease with stage-specific gene expression changes occurring in multiple organs over time. The temporal sequence and the extent of gene regulatory network changes occurring across organs during the development of hypertension remain unresolved. In this study, female spontaneously hypertensive (SHR) and normotensive Wistar Kyoto (WKY) rats were used to analyze expression patterns of 96 genes spanning inflammatory, metabolic, sympathetic, fibrotic, and renin-angiotensin (RAS) pathways in five organs, at five time points from the onset to established hypertension. We analyzed this multi-dimensional dataset containing ~15,000 data points and developed a data-driven dynamic network model that accounts for …

Perceptions And Use Of The Athletic Training Milestones In Education: A Report From The Aate Research Network, Cailee E. Welch Bacon, Barton E. Anderson, Julie M. Cavallario, Bonnie L. Van Lunen, Lindsey E. Eberman

Clinical Practice in Athletic Training

The Athletic Training Milestones (AT Milestones) were developed as an evaluation tool to capture the breadth and depth of athletic training knowledge, skills, and behavior. However, it is unclear whether athletic training programs are implementing this tool or how they are implementing it to gauge the clinical progression of students or residents in athletic training. We aimed to explore the perceptions and use of the AT Milestones among educators in athletic training programs. We used a cross-sectional, web- based survey with open-ended questions to collect data from athletic training programs on if and how they implement the AT Milestones at …

Altered Extracellular Matrix Correlates With An Immunosuppressive Tumor Microenvironment And Disease Progression In Younger Adults With Oral Cavity Squamous Cell Carcinoma, Leonard Estephan, Gaurav Kumar, Matthew Stewart, Raphael Banoub, Alban Linnenbach, Larry Harshyne, Ubaldo Martinez-Outshoorn, My Mahoney, Joseph Curry, Jennifer Johnson, Andrew South, Adam Luginbuhl

Kimmel Cancer Center Faculty Papers

INTRODUCTION: Oral cavity squamous cell carcinoma (OSCC) occurs most frequently in patients >60 years old with a history of tobacco and alcohol use. Epidemiological studies describe increased incidence of OSCC in younger adults (years). Despite its poor prognosis, knowledge of OSCC tumor microenvironment (TME) characteristics in younger adults is scarce and could help inform possible resistance to emerging treatment options.

METHODS: Patients with OSCC were evaluated using TCGA-HNSC (n=121) and a stage and subsite-matched institutional cohort (n=8) to identify differential gene expression focusing on the extracellular matrix (ECM) and epithelial-mesenchymal transition (EMT) processes in younger (≤45 years) vs. older adults …

T-Cell Redirecting Bispecific Antibodies: A Review Of A Novel Class Of Immuno-Oncology For Advanced Prostate Cancer, Julia Palecki, Amman Bhasin, Andrew Bernstein, Patrick Mille, William Tester, William Kelly, Kevin Zarrabi

Kimmel Cancer Center Faculty Papers

Novel T-cell immunotherapies such as bispecific T-cell engagers (BiTEs) are emerging as promising therapeutic strategies for prostate cancer. BiTEs are engineered bispecific antibodies containing two distinct binding domains that allow for concurrent binding to tumor-associated antigens (TAAs) as well as immune effector cells, thus promoting an immune response against cancer cells. Prostate cancer is rich in tumor associated antigens such as, but not limited to, PSMA, PSCA, hK2, and STEAP1 and there is strong biologic rationale for employment of T-cell redirecting BiTEs within the prostate cancer disease space. Early generation BiTE constructs employed in clinical study have demonstrated meaningful antitumor …

Analysis Of Antibiotic Sensitivity Patterns In Pasteurellaceae Family Isolates: A Microbial And Molecular Investigation, Jillian Barron

Honors Scholar Theses

Bacteria in the Pasteurellaceae family are known to cause disease in both human and animal species. Like all species of bacteria, the pathogens in the Pasteurellaceae family evolve and acquire antimicrobial-resistant traits. Antimicrobial resistance of bacteria is a significant public health concern, as treatment of resistant pathogens becomes more difficult, if not impossible, with current medical capabilities. In this project, phenotypic and genotypic analyses were performed on Pasteurellaceae family isolates sourced from the Connecticut Veterinary Medical Diagnostic Laboratory. Phenotypic antibiotic sensitivity patterns of each isolate were assessed against a panel of antibiotics through a Kirby-Bauer disk diffusion test. Disk diffusion …

Rowan-Virtua School of Osteopathic Medicine Departmental Research

BACKGROUND: Digital neuropsychological tests reliably capture real-time, process-based behavior that traditional paper/pencil tests cannot detect, enabling earlier detection of neurodegenerative illness. We assessed relations between informant-based subtle and mild functional decline and process-based features extracted from the digital Trail Making Test-Part B (dTMT-B).

METHODS: A total of 321 community-dwelling participants (56.0% female) were assessed with the Functional Activities Questionnaire (FAQ) and the dTMT-B. Three FAQ groups were constructed: FAQ = 0 (unimpaired); FAQ = 1-4 (subtle impairment); FAQ = 5-8 (mild impairment).

Results: Compared to the FAQ-unimpaired group, other groups required longer pauses inside target circles (p < 0.050) and produced more total pen strokes to complete the test (p < 0.016). FAQ-subtle participants required more time to complete the entire test (p …
