Research outputs 2022 to 2026

In this study, it is aimed to establish a novel method based on a deep-learning-guided surface-enhanced Raman spectroscopy (SERS) technique to achieve rapid and accurate classification of vaginal cleanliness levels. We proposed a variational autoencoder (VAE) approach to enhance spectral quality, coupled with a deep learning algorithm long short-term memory (LSTM) neural network to analyze SERS spectra produced by vaginal secretions. The performance of various machine learning (ML) algorithms is assessed using multiple evaluation metrics. Finally, the reliability of the optimal model is tested using blind test data (N = 10/group for each cleanliness level). The data quality of the …

Focused Assessment With Sonography Exams Vs Ct Scan, Anne Kresge, Charlotte Mueller, Briar Tures

Physician Assistant Capstones, 2020-current

Blunt trauma is a common reason patients present to the emergency department. Providers must evaluate these patients quickly to get them the correct treatment, especially for intra-abdominal bleeding. Focused assessment with sonography for trauma (FAST) exams are growing in use to evaluate trauma patients for free fluid in the abdomen. To be valuable to emergency providers, it must be known how FAST exams compare to the gold standard evaluation, computed tomography (CT) scans. Searches were done on Pubmed and Scopus databases using terms “focused assessment with sonography for trauma” and “FAST exam CT blunt abdominal trauma.” Limits were added to …

Paper-Based Ratiometric Sensor Array For Pathogenic Bacterial Species Identification, Aayushi Laliwala

Theses & Dissertations

Bacterial infections are the leading cause of mortality worldwide due to the lack of accurate diagnosis of the pathogens causing infections. Currently, microbiological and molecular techniques are used to identify pathogenic bacteria. However, these techniques have limitations as they are time-consuming, cost-inefficient, and require trained personnel. Therefore, timely and precise identification of pathogenic bacteria is crucial for public safety. Our lab previously synthesized a fluorescent sensor array (3-hydroxyflavone derivatives) encapsulated in hyaluronic acid-based nanoparticles to identify bacterial species and recognize their Gram status. Though promising, this technique was relatively time-consuming and required high sample and volumes.

To overcome these limitations, …

School of Medicine Faculty Publications

Potentially septic patients have a huge clinical and economic impact on hospitals and often present to the emergency department (ED) with undifferentiated symptoms. The triage of these patients is complex and has historically relied heavily upon provider judgment. This study aims to evaluate the consistency of provider judgment and the potential of a new host response sepsis test to aid in the triage process. A modified Delphi study involving 26 participants from multiple specialties was conducted to evaluate provider agreement about sepsis risk and to test proposed actions based on the results of a sepsis test. The participants considered case …

Raman Spectroscopic Analysis Of Human Serum Samples Of Convalescing Covid-19 Positive Patients, Hugh Byrne, Naomi Jackson, Jaythoon Hassan

Articles

Rapid screening, detection and monitoring of viral infection is of critical importance, as exemplified by the rapid spread of SARS-CoV-2, leading to the worldwide pandemic of COVID-19. This is equally the case for the stages of patient convalescence as for the initial stages of infection, to understand the medium and long terms effects, as well as the efficacy of therapeutic interventions. Optical spectroscopic techniques potentially offer an alternative to currently employed techniques of screening for the presence, or the response to infection. In this study, the ability of Raman spectroscopy to distinguish between samples of the serum of convalescent COVID-19 …

Validity And Test-Retest Reliability Of A Digital Dynamic Visual Acuity Test Of Vestibular Function, Lydia F. Grunstra, Courtney D. Hall, Kara D. Stressman

Undergraduate Honors Theses

The vestibular system senses head motion and facilitates gaze stabilization, allowing for clear vision during movement. The vestibulo-ocular reflex (VOR) causes the eyes to move opposite head motion, thus maintaining focus on a target. Consequently, uncompensated loss of vestibular function leads to reduced VOR function resulting in dizziness, nausea, and visual disturbance. Different testing methods have been developed to measure VOR loss. These tests generally require bulky, expensive equipment, and must be performed by a trained examiner. A newly developed digital form of the dynamic visual acuity (DVA) test requires less equipment, is cost-effective, and may be performed at home …

Ultrasound can be a useful tool in the diagnosis because it is easily accessible and can be rapidly acquired. We report a case that demonstrates the utility of ultrasound in the diagnosis of a superficial temporal artery pseudoaneurysm.

Assessing Virtual Versus In-Person Experiential Learning And Medical High-Fidelity Simulation In Medical Student Pediatric Clerkship Training, Andrew Mitchell Berry

Electronic Theses and Dissertations

Simulation and experiential training have been incorporated into medical school training for decades. The utilization of medical simulations has become an invaluable tool in healthcare education and training. However, circumstances such as limited resources, geographical constraints, or global health crises may hinder the feasibility of conducting in-person medical simulations. In these scenarios, virtual medical simulations emerge as a compelling alternative. While there are many ways to accomplish experiential-based learning, many faculty and students feel Socratic learning styles provide the best learning experience.

As medical students had just finished a predominantly virtual preclinical year due to the COVID-19 pandemic, the research …

The Core Cognitive Evaluation™ (CCE) is administered/scored using an iPad, requires approximately 8 min, assesses 3- word free recall and clock drawing to command and copy, asks questions about lifestyle and health, and queries for psychological distress. This information is linked with patients' self- reported concerns about memory and their cardiovascular risks.

METHODS: A total of 199 ambulatory patients were screened with the CCE as part of their routine medical care. The CCE provides several summary indices, and scores on …

Left Juxtaposition Of The Right Atrial Appendage: Pitfalls In Diagnosis, Kanya Singhapakdi, Wesam Sourour, Thomas Kimball

School of Medicine Faculty Publications

Several congenital anomalies of the right atrial appendage (RAA) have been described including aneurysm, herniation (in association with a pericardial defect), and left juxtaposition. The left juxtaposition of the RAA (LJRAA), first described by Birmingham in 1893 and subsequently introduced by Dixon in 1954, is usually associated with complex cardiac malformations such as obstruction of the left ventricular outflow tract. In this case report, we will describe an unusual variant of LJRAA in the absence of any other cardiac defects, which was initially misinterpreted as an aortic dissection. The correct diagnosis was made after careful reinterpretation and the use of …

Sarcopenic Obesity, Pathogenesis, And Treatment With A Focus On Exercise And Protein Intake, Yasemin Karaağaç

Journal of Mind and Medical Sciences

Sarcopenic obesity involves the co-occurrence of sarcopenia and obesity, yields more health risks than either condition alone, thus requiring prevention and treatment for healthy aging. In this review, the literature on the diagnosis of sarcopenic obesity, the mechanisms of its pathogenesis and treatment with emphasis on exercise and dietary protein were revised. Changes in body composition and sex hormones with age, myocellular mechanisms, inflammation, oxidative stress, physical inactivity, and insufficient protein intake are the main factors associated with the pathogenesis of sarcopenic obesity. Treatment targets weight loss while preserving muscle mass and function. Promising approaches involve high-protein and low-calorie diets …

Unusual Inflammatory Presentation For Locally Advanced Papillary Thyroid Carcinoma, Ana I. Vargas, Samuel K. Snyder

Research Symposium

Background: Thyroid cancer usually presents as a thyroid nodule. If the history implies rapid growth of the nodule, new onset hoarseness or presence of ipsilateral cervical lymphadenopathy then it should raise concern for malignancy. Deep neck infection/inflammation has rarely been reported as initial presentation and these patients are potentially misdiagnosed.

Case Presentation: We present a 56-year-old male who comes to clinic for evaluation of left neck nodule. He started two weeks prior with sudden neck swelling associated with erythema and pain in his lower neck that caused choking sensation and swallowing discomfort, he was prescribed Bactrim and prednisone with improvement …

Using Cartesian Coordinate Systems To Create, Classify, And Retrieve Biomedical Time-Series: Applications To 24-Hour Ambulatory Blood Pressure Monitoring, Antonio Garcia, Gladys E. Maestre, John Blangero, Jesus D. Melgarejo, Julio Facelli

Research Symposium

Background: Ambulatory Blood Pressure Measurement (ABPM) allows physicians to monitor blood pressure variability under everyday living conditions and predicts clinical outcomes better than conventional blood-pressure measurement. ABPM can demonstrate mean arterial pressure (MAP) behavior over 24 hours relevant to clinical practice, such as nocturnal hypertension or increased blood pressure variability. We hypothesized that individuals with the same cardiovascular health status would have the same MAP signal (MAPs) waveform.

Methods: This study reutilizes a data subset from the IDACO Consortium to create 24-hour MAPs. We assigned all the MAPs to data matrix X, performed principal components analysis (PCA) to X, and …
