A Comparison Of Opioid Abuse Screening Tools Of Detection Of High Risk Patients In The Inpatient Setting, Grace Gu Md, Albert Cheng Md, Darren Rahaman Md, Shyh-Jeun Wang Md, Maureen Strohm Md, Napatkamon Ayutyanont

Family Medicine

• The United States is currently experiencing an opioid epidemic, which claims 115 lives daily by overdose.
• Tools for identifying patients at increased risk for abuse include: Screener and Opioid Assessment for Patients with Pain (SOAPP-R) and Opioid Risk Tool (ORT).
• However, data is lacking for the comparison of the two most commonly used opioid screen tools (SOAPP-R and ORT).
• We are comparing the effectiveness of these screening tools for patients being discharged from the hospital who have no "red flags" for abuse.

Predicting Premature Birth Risk With Cfrna, Jason Lin, Jonathan Marin, John Santerre

SMU Data Science Review

Identifying which genes are early indicators for preterm births using cell-free ribonucleic acid (cfRNA) from non-invasive blood tests provided by pregnant women can improve prenatal care. Currently, there are no medical tests for early detection of preterm birth risk in routine checkups for pregnant women. Recent studies have shown potential genes that can predict preterm birth. Machine learning techniques are utilized to see if the Area Under the Curve (AUC) can be improved upon when evaluating the prediction accuracy for chosen genes sequences and concentrations. Using cell-free RNA data from non-invasive blood tests in conjunction with machine learning, we improve …

Endovascular Management Of Free Floating Common Carotid Thrombi, Kevin Carr Md, Zachary Thwing Md, Ravishankar Shivashankar Md, Yafell Serulle Md

Radiology

• The incidence of symptomatic free-floating thrombi of the common carotid artery (CCA) is as low as 0.24-5% incidence in stroke victims. Patients are predisposed to a prothrombotic state
• Historical management options were limited to surgical and medical options both with individual attendant risk profiles
• Large thrombi can present with various degrees of clinical severity
• The endovascular approach is a viable tool to manage these patients

Cell-Free Dna Release During Programmed Cell Death In Ischemia Reperfusion Injury, Alexander Dionne, Anthony M. Jevnikar, Zhu-Xu Zhang

Western Research Forum

Transplantation is invariably associated with acute allograft injury caused by ischemia reperfusion injury (IRI). This injury causes cells of the allograft to undergo various forms of programmed cell death including apoptosis and necroptosis. During programmed cell death, immunogenic molecules are released from cells, one of which is cell-free DNA (cfDNA). We hypothesize that cfDNA is released by microvascular endothelial cells (MVECs) during programmed cell death of IRI and that cfDNA acts as both a biomarker for cellular injury as well as a biologically active molecule capable of amplifying inflammation and organ injury.

Our results indicate that cfDNA is released by …

Use Of Clinical Test Clusters Versus Advanced Imaging Studies In The Management Of Patients With A Suspected Slap Tear, Richard C. Clark, Chasiti C. Chandler, Andrew C. Fuqua, Kelly N. Glymph, Grayson C. Lambert, Katherine J. Rigney

Physical Therapy Faculty Research

Background and Purpose

The Magnetic Resonance Arthrogram (MRA) has served as the gold standard for identifying patients with possible Superior Labrum Anterior-Posterior (SLAP) lesions and are often required by orthopaedic surgeons prior to clinical evaluation. However, as the literature shows MRA sensitivity as 0.65-0.98, and specificity between 0.80-1.00, there is still room for misinterpretation of the imaging study, and potential mismanagement of a patient who may or may not exhibit a true SLAP lesion. It is proposed that by grouping a series of clinical special tests it may be possible to develop greater sensitivity in identifying a SLAP lesion, resulting …

Crystal Structure Of Zymonic Acid And A Redetermination Of Its Precursor, Pyruvic Acid, Dominik Heger, Alexis J. Eugene, Sean R. Parkin, Marcelo I. Guzman

Chemistry Faculty Publications

The structure of zymonic acid (systematic name: 4-hy­droxy-2-methyl-5-oxo-2,5-di­hydro­furan-2-carb­oxy­lic acid), C₆H₆O₅, which had previously eluded crystallographic determination, is presented here for the first time. It forms by intra­molecular condensation of parapyruvic acid, which is the product of aldol condensation of pyruvic acid. A redetermination of the crystal structure of pyruvic acid (systematic name: 2-oxo­propanoic acid), C₃H₄O₃, at low temperature (90 K) and with increased precision, is also presented [for the previous structure, see: Harata et al. (1977). Acta Cryst. B33, 210–212]. In zymonic acid, the hy­droxy­lactone ring …

Scintillation Event Localization In Novel Hemi-Ellipsoid Detector For Spect, Hanif R. Soysal

LSU Master's Theses

A high sensitivity Cardiac SPECT system using hemi-ellipsoid crystals with pinhole collimation was previously proposed by Dey et al. To investigate detector resolution for this design, the scintillation light spread on a monolithic hemi-ellipsoidal CsI crystal was simulated using Geant4 Monte Carlo. The expected distribution of scintillation light on the outer surface of the crystal from photoelectric absorption events was obtained from the simulations for selected points inside the crystal. Two sets of simulations were performed. For the first set, a look-up table (LUT) of 12 points was created and each point mapped to its expected light distribution—four points at …

Utilizing Simulation To Implement Cognitive Aids In The Operating Room, Kaitlyn Brown

Doctor of Nursing Practice Projects

Background: Operating room crises require prompt, efficient action to avoid detrimental outcomes. Research shows that crisis checklists or other cognitive aids assist anesthesia providers in taking prompt action while improving efficiency by decreasing treatment steps missed during critical events.

Objectives: The purpose of this project was to evaluate the effectiveness of incorporating cardiac arrest and malignant hyperthermia crisis checklists into the operating room using high-fidelity simulation-based education.

Methods: Researchers implemented the Stanford Emergency Manual Cognitive Aids for cardiac arrest and malignant hyperthermia to anesthesia staff at a community hospital in southern Illinois with 18 participants. Implementation consisted of an education …

Differential Estimation Of Audiograms Using Gaussian Process Active Model Selection, Trevor Larsen

McKelvey School of Engineering Graduate Student Theses & Dissertations

Classical methods for psychometric function estimation either require excessive resources to perform, as in the method of constants, or produce only a low resolution approximation of the target psychometric function, as in adaptive staircase or up-down procedures. This thesis makes two primary contributions to the estimation of the audiogram, a clinically relevant psychometric function estimated by querying a patient’s for audibility of a collection of tones. First, it covers the implementation of a Gaussian process model for learning an audiogram using another audiogram as a prior belief to speed up the learning procedure. Second, it implements a use case of …

Acute Promyelocytic Leukemia: A Case Study Correlating Cytogenetic Abnormality With Prognosis, Alyssa Lamond, Theresa Tellier-Castellone

Senior Honors Projects

Advancements in medical technology today have positively impacted the diagnosis, treatment, and prognosis of cancers. Particularly acute promyelocytic leukemia (APL) has completely improved from having the poorest prognosis to one of the best. Acute promyelocytic leukemia is a malignant disease of hematopoietic tissue classified by WHO as leukemia with >20% blasts from the myeloid lineage, specifically promyelocytes. Determined in 1976, FAB classified AML subtypes M1-M7, with APL being M3. Specific characteristics classify the subtype of AML, with each resulting from a different genetic abnormality. The focus of APL diagnosis, treatment, and prognosis occurs around the known PML-RARα fusion gene. Flow …

Simulating Alternative Tuberculosis Diagnosis Methods In Underdeveloped Countries, Luke Turner

Industrial Engineering Undergraduate Honors Theses

Tuberculosis is the deadliest infectious disease in the world; it is especially rampant in underdeveloped countries because they do not have the infrastructure, technology, or funding to properly combat the infection. However, the development of portable point-of-care diagnosis machines can reverse this epidemic as they far surpass conventional laboratory identification. The question now is where to place these machines, which is a difficult decision with a lack of data. Therefore, a flexible simulation model is created to test the implementation of these machines with different countries and configurations. The simulation tests the baseline model and three proposed implementations of the …

Seeing Eye To Eye: A Machine Learning Approach To Automated Saccade Analysis, Maigh Attre

Honors Scholar Theses

Abnormal ocular motility is a common manifestation of many underlying pathologies particularly those that are neurological. Dynamics of saccades, when the eye rapidly changes its point of fixation, have been characterized for many neurological disorders including concussions, traumatic brain injuries (TBI), and Parkinson’s disease. However, widespread saccade analysis for diagnostic and research purposes requires the recognition of certain eye movement parameters. Key information such as velocity and duration must be determined from data based on a wide set of patients’ characteristics that may range in eye shapes and iris, hair and skin pigmentation [36]. Previous work on saccade analysis has …

Correlation Between Myostatin And Lean Muscle Mass In Older Adults, Mishann Luedders

The Eleanor Mann School of Nursing Undergraduate Honors Theses

Correlation Between Myostatin and Lean Muscle Mass in Older Adults.

Luedders, M., Gray, M., Patton, S., Washington, T., Binns, A. Exercise Science Research Center, University of Arkansas, Fayetteville, AR.

Background: Our older adult population is growing exponentially and with it, the number of falls and debilitating injuries that afflict their population grows as well. A fall brings with it many possible injuries, healthcare costs, fear and increased mortality. There seems to be a lack of preventative measures in our healthcare system to help protect our elders. One possible measure is a simple blood test that looks at the level of …

Novel Mechanisms And Biomarkers In Alcohol-Induced Organ Injury., Christine E. Dolin

Electronic Theses and Dissertations

Background. Ethanol (EtOH) consumption is known to affect multiple organs; this is unsurprising, as the concentration of EtOH in the blood at relevant doses reaches the millimolar range. The overarching goal of this dissertation was to elucidate mechanisms of alcohol-induced organ injury, specifically the effects of alcohol on the hepatic extracellular matrix (ECM) proteome, the alcoholic hepatitis (AH) plasma peptidome, and the effects of alcohol on the renal cortex proteome and transcriptome. Methods. Mice were pair-fed ethanol-containing liquid diet chronically, and then some mice were administered lipopolysaccharide (LPS). Liver sections from these mice were processed in a series of increasingly …
