What Is Scannable? An Mri Safety Guide, Michael Burcescu, Ravi Patel, Robert Hessemer, Peter Lore, Sriharsha Kota, Guarav Kumar

West Florida Division GME Research Day 2020

Supernumerary MRI protocols and recommendations exist to guide physicians at the forefront of patient care. While urgent imaging may be necessary for critical patients, inadvertent imaging of implantable devices can incur serious morbidity and mortality[11]. The American College of Radiology published a 30-page manual in 2013[1] on MRI safe practices and releases yearly updates with critical information separately[2]. There is increased utilization of advanced imaging modalities, especially among academic institutions[3]. Physicians are hard pressed to maximize efficiency; uncertainty delays imaging. Moreover, inappropriate orders delay appropriate management. We present pertinent and often questioned considerations in a comprehensible format along with devices …

Functional Balance Assessment Of Firefighters During Mass-Screening Examinations, Rachel M. Eiler, Zachary K. Winkelmann, Kenneth E. Games

Clinical Practice in Athletic Training

Firefighters are tactical athletes who are required to complete rigorous tasks as part of their job functions. The focus of this clinical outcomes assessment was to assess functional balance assessment through the use of the anterior reach test with and without personal protective equipment (PPE) during a mass-screening examination. The screening was completed with 61 active firefighters in a local fire department with access to athletic training services. The results of the anterior reach assessment identified a significant difference of a firefighter’s anterior reach when donning and doffing PPE. Anterior reach distances were significantly reduced (P < 0.001) on the right leg with (mean = 55.78 cm ± 7.53 cm) and without PPE (mean = 58.92 cm ± 6.47 cm). Similarly, significant decrements (P = 0.003) in left leg anterior reach distance in firefighters donning (mean = 57.67 cm ± 8.25 cm) and doffing (mean = 59.82 cm ± 6.31 cm) PPE. Clinical application of these findings suggests that healthcare providers working with tactical athletes, specifically firefighters, should consider the risks associated with donning PPE such as functional balance deficits.

Deep Vein Thrombosis In Lower Extremity Of A Female Collegiate Volleyball Athlete: A Case Study, Lucas D. Dargo, Kendra Borton, Rachel Roths, Zachary Dougal

Clinical Practice in Athletic Training

Deep vein thrombosis (DVT) occurs when a blood clot forms in deep veins in the body, usually in the lower extremity. DVT is commonly seen in older or hospitalized patients. This case is unique because the patient is a 20-year-old female division III collegiate volleyball athlete, which is not the typical age or population affected by DVT or clotting disorders. The patient presented with swelling, pain, and decreased knee flexion (3/5) and plantarflexion (4/5) strength in her left lower extremity. These impairments reduced her ability to walk or run. The patient’s athletic trainer (AT) initially diagnosed her with a left …

Multi-Modal Medical Imaging Analysis With Modern Neural Networks, Gongbo Liang

Theses and Dissertations--Computer Science

Medical imaging is an important non-invasive tool for diagnostic and treatment purposes in medical practice. However, interpreting medical images is a time consuming and challenging task. Computer-aided diagnosis (CAD) tools have been used in clinical practice to assist medical practitioners in medical imaging analysis since the 1990s. Most of the current generation of CADs are built on conventional computer vision techniques, such as manually defined feature descriptors. Deep convolutional neural networks (CNNs) provide robust end-to-end methods that can automatically learn feature representations. CNNs are a promising building block of next-generation CADs. However, applying CNNs to medical imaging analysis tasks is …

Living With Pku: The Lived Experience Of Irish Adults With Early Diagnosed Phenylketonuria On Long Term Dietary Therapy, Mary-Ellen O'Shea

Theses

Phenylketonuria (PKU) is a rare genetic condition affecting the body’s ability to metabolise the amino acid phenylalanine (PHE). A build-up of PHE in the blood and brain can result in irreversible intellectual disability and developmental delays. Ireland has one of the highest prevalence rates of PKU in Europe and some of the earliest treated patients with PKU in the world. However, little is known about their lived experience with PKU. Furthermore, cost-benefit analysis of treatments for rare diseases in Ireland is principally based on quantitative data. More qualitative data is needed to highlight the quality of life experienced by people …

Identifying Metabolites As Markers Of Fatigue In Athletes, Christopher D. George

Honors Theses

Fatigue in athletes caused by inadequate rest and other stressors can be severely detrimental to their health, and yet there is no reliable way to measure and track fatigue. Many classical measures of fatigue like body mass and resting heart rate are not reliable ways to track the physical fatigue of an athlete because they can change with many factors. In addition, it is not known how academic stress on top of physical stress affects fatigue. Metabolomics is a relatively new area of study and tracking metabolites offers the possibility to produce biomarkers to assess fatigue. This study collected saliva …

Mass Spectrometry Based Lipidomic Investigation Of Staphylococcus Aureus Lipid Metabolism And Characterization Of Lipase A, Naren Gajenthra Kumar

Theses and Dissertations

Staphylococcus aureus produces an arsenal of virulence factors and is adept at colonizing multiple hosts by employing specific processes to persist at different sites of infection. Infections caused by this pathogen range from self-limiting infections of the skin like folliculitis to life threatening and chronic conditions like infective endocarditis, non-healing diabetic foot ulcers and atopic dermatitis. As the field continues to expand its understanding of the mechanisms by which this pathogen rapidly develops resistance to new antibiotics, the underlying mechanisms that facilitates niche adaptation and host colonization among healthy individuals remain elusive.

Bacterial and host lipid metabolism presents and area …

Comparability Of Raman Spectroscopic Configurations: A Largescale Cross-Laboratory Study, Shuxia Guo, Hugh Byrne, Shiyamala Duraipandian, Fiona Lyng, Claudia Beleites, Ute Neugebauer

Articles

The variable configuration of Raman spectroscopic platforms is one ofthe major obstacles in establishing Raman spectroscopy as a valuable physicochemicalmethod within real-world scenarios such as clinical diagnostics. For such real worldapplications like diagnostic classification, the models should ideally be usable to predictdata from different setups. Whether it is done by training a rugged model with data frommany setups or by a primary-replica strategy where models are developed on a‘primary’setup and the test data are generated on‘replicate’setups, this is only possible if the Raman spectra from different setups are consistent, reproducible, and comparable.However, Raman spectra can be highly sensitive to the …
