Carcinoma With Osteoclast-Like Giant Cells: A Rare Histologic Variant Of Breast Cancer, Robert Bender, Makenna Bowman, Matthew Lee, Susana Ferra

East Florida Division GME Research Day 2025

Introduction: Osteoclast like giant cells (OGCs) can be found in various tissues such as the gallbladder, liver, pancreas, and thyroid. In breast cancer, the presence of OGCs is a rare finding. Currently knowledge of such cases is limited, with approximately 200 reported cases of osteoclast like giant cells (OGCs) among all breast carcinomas. Among the breast cancers that are classified as rare, those with OGCs make up only 0.5-1.2% of cases.

Case Description: An 80+ year-old female presented with a palpable left breast lesion initially suspected by mammography as a benign lesion. She eventually underwent breast core biopsy revealing hormone …

Four Overlooked Errors In Roc Analysis: How To Prevent And Avoid, Zhuoqiao He, Qingying Zhang, Manshu Song, Xuerui Tan, Wei Wang Jan 2025

Four Overlooked Errors In Roc Analysis: How To Prevent And Avoid, Zhuoqiao He, Qingying Zhang, Manshu Song, Xuerui Tan, Wei Wang

Research outputs 2022 to 2026

Diagnostic tests are frequently applied within clinical practice to assist with disease diagnosis, differential diagnosis, disease grading and prognosis evaluation. Receiver operating characteristic (ROC) curve analysis is one common approach for analysing discriminative performance of a diagnostic test, where it can determine the optimal cut-off value with the best diagnostic performance.1 However, as a majority of clinicians are non-statisticians, several errors have been observed in clinical research when applying ROC curves. These errors may be misleading in the selection of diagnostic tests and disease diagnosis, thus adding to patient burden. To address these errors, clinicians do not need a …


Artificial Intelligence In Cancer-Related Malnutrition And Cachexia: A Transformative Tool In Clinical Nutrition, Salvatore Carbone Jan 2025

Artificial Intelligence In Cancer-Related Malnutrition And Cachexia: A Transformative Tool In Clinical Nutrition, Salvatore Carbone

EVMS School of Health Professions Faculty Publications

[Introduction] Malnutrition and cachexia are common complications in cancer patients, and they negatively influence prognosis, treatment efficacy, and tolerability as well as quality of life [[1], [2], [3]]. Accurately identifying and effectively managing malnutrition and cachexia in this population remains a clinical challenge. Conventional validated screening tools may lack the sensitivity and specificity required for early detection and personalized intervention in diverse cancer types and treatment settings [4,5]. Over the last decade, the use of artificial intelligence (AI), including machine learning (ML) and deep learning (DL) strategies, has shown promising results in clinical nutrition, with the potential to revolutionize nutritional …

The Anatomy Of A Reconstruction: From Fourier Space To Image Recovery In Computed Tomography, Charlotte P. Maurer Jan 2025

The Anatomy Of A Reconstruction: From Fourier Space To Image Recovery In Computed Tomography, Charlotte P. Maurer

Honors Theses

This thesis develops the mathematical foundations of computed tomography (CT) reconstruction through the lens of harmonic analysis. Beginning with the Schwartz class, we introduce the Fourier transform and its role in expressing the Radon transform and its inversion via a fractional Laplacian. After constructing the Radon transform in general dimension R^d, we specialize to the cases d = 2 and d = 3, demonstrating explicit inversion formulas and the associated instability in lower dimensions. For its computational advantages, we study filtered back-projection using classical low-pass filters (Ram-Lak, Shepp–Logan, Cosine, Gaussian) and formulate a discrete reconstruction algorithm grounded in …


An Analytical Model Of Motion Artifacts In A Measured Arterial Pulse Signal—Part Ii: Tactile Sensors, Md Mahfuzur Rahman, Subodh Toraskar, Mamun Hasan, Zhili Hao Jan 2025

An Analytical Model Of Motion Artifacts In A Measured Arterial Pulse Signal—Part Ii: Tactile Sensors, Md Mahfuzur Rahman, Subodh Toraskar, Mamun Hasan, Zhili Hao

Mechanical & Aerospace Engineering Faculty Publications

This paper, the second of two parts, presents an analytical model of motion artifacts (MA) in measured pulse signals by a tactile sensor, which contains a deformable microstructure sitting on a substrate. While the tissue-contact-sensor (TCS) stack and the sensor are both treated as a 1DOF (degree-of-freedom) system, tissue–sensor contact joins their mass together to form a 1DOF system with springs and dampers on both sides. MA on the sensor substrate causes baseline drift and time-varying system parameters (TVSP) of the TCS stack simultaneously. An analytical model is developed to mathematically relate baseline drift and TVSP to a measured pulse …

Background

Appendicular lean mass index is a major determinant of cardiorespiratory fitness in patients with obesity-related heart failure with preserved ejection fraction (HFpEF). Moreover, appendicular lean mass index can be used to diagnose sarcopenia and sarcopenic obesity in this population. We aimed to validate the ability of segmental single-frequency bioelectrical impedance analysis (SF-BIA) to assess body composition compared with dual-energy x-ray absorptiometry (DXA) in patients with HFpEF and obesity, with a focus on appendicular lean mass index for its critical role in diagnosing sarcopenia and sarcopenic obesity.

Methods

We analyzed 62 euvolemic patients from a heart failure outpatient clinic with …


Why Ai Monitoring Faces Resistance And What Healthcare Organizations Can Do About It: An Emotion-Based Perspective, Karl Werder, Lan Cao, Eun Hee Park, Balasubramaniam Ramesh Jan 2025

Why Ai Monitoring Faces Resistance And What Healthcare Organizations Can Do About It: An Emotion-Based Perspective, Karl Werder, Lan Cao, Eun Hee Park, Balasubramaniam Ramesh

Information Technology & Decision Sciences Faculty Publications

Continuous monitoring of patients' health facilitated by artificial intelligence (AI) has enhanced the quality of health care, that is, the ability to access effective care. However, AI monitoring often encounters resistance to adoption by decision makers. Healthcare organizations frequently assume that the resistance stems from patients' rational evaluation of the technology's costs and benefits. Recent research challenges this assumption and suggests that the resistance to AI monitoring is influenced by the emotional experiences of patients and their surrogate decision makers. We develop a framework from an emotional perspective, provide important implications for healthcare organizations, and offer recommendations to help reduce …

Initiation Of Sterile Vaginal Preps Prior To Cesarean Sections: A Quality Improvement Project, Diane Gilbertson, Timothy Kremer, Kimberly Udell

North Texas Research Forum 2025

OBJECTIVE: Research on patients undergoing routine gynecological procedures with a vaginal preparation has demonstrated a significant reduction in post-operative infections by decreasing the burden of vaginal bacteria. Despite this research, as well as evidence that they reduce postpartum endometritis, especially in labor patients or those with ruptured membranes (Lui), vaginal preparations prior to cesarean section are not standard practice. Prior to the initiation of this quality improvement project, no patients delivering at Medical City Arlington received a vaginal preparation prior to a cesarean delivery. The goal of this quality improvement project is to improve clinical care, patient safety, and healthcare …

Improving Communication And Follow Up For Incidental Findings From Panscan Imaging, Makenzie Morrissey, Kristen Payne, Randall Rittmann, Chris Robert, Joseph Lim, Danielle Pigneri

North Texas Research Forum 2025

OBJECTIVE: Incidental findings in medical imaging pose a significant challenge in healthcare due to the potential for missed follow-ups, which can lead to adverse outcomes for patients. These findings, which are unrelated to the primary purpose of the imaging study, are increasingly common due to advances in imaging technology and its widespread use. The consequences of missed follow-ups can be severe. For instance, the rate of malignancy in incidental pulmonary nodule id about 5% and follow up fails in 30-70% of cases. This means for every 120 CT chest scans ordered, 1 lung cancer is missed (McWilliams et al., 2013). …

Real Time Non-Targeted Renal Biopsy Adequacy Evaluation: A Successful Quality Improvement Activity, Astrid Sacasa, Susana Ferra

East Florida Division GME Research Day 2025

Introduction. Adequate renal biopsies are essential for the diagnosis and treatment of medical renal disease. This process requires a sufficient number of glomeruli for light microscopy, immunofluorescence, and electron microscopy evaluation. On-site microscopic evaluation of kidney biopsy specimens significantly improves sample adequacy and the ability to render a diagnosis, with studies showing a much higher rate of inadequate samples when on-site evaluation is absent. Inadequate biopsies can have a significant negative impact on patient care including delay of adequate diagnoses, worsening of the patients’ condition and complications, and increasing costs due to the need for repeat biopsies. A real time …
