Development, Validation, And Diagnostic Performance Of A Novel Radiomic Model For Predicting Prostate Cancer Recurrence, Linda M. Huynh

Theses & Dissertations

Multi-parametric magnetic resonance imaging (MP-MRI)-derived radiomics have been shown to capture sub-visual patterns for the quantitative characterization of prostate cancer (PC) phenotypes. The present dissertation seeks to develop, evaluate, and compare the performance of an MRI-derived radiomic model for the prediction of PC recurrence following definitive treatment with radical prostatectomy (RP).

MP-MRI was obtained from 339 patients who had a minimum of 2 years follow-up following RP at three institutions. The prostate was manually delineated as the region of interest and 924 radiomic features were extracted. All features were evaluated for stability via intraclass correlation coefficient (ICC) and image normalization …

Development And Implementation Of An Evidence Based Practice Guideline Related To The Management Of Adult Angioedema, Megan Przybysz

Doctor of Nursing Practice Scholarly Projects

Angioedema (AE) is a potentially life-threatening medical condition that occurs with a higher frequency than medical providers may expect, with the emergency department (ED) serving as the usual first point of medical contact for patients. Any hesitation in recognizing AE or inconsideration of the disease process in differential diagnoses may lead to a dangerous delay of care. Due to the potential rapid progression of airway obstruction in AE, inexperienced providers should not attempt intubation, instead deferring to providers experienced in alternative airway techniques (i.e., anesthesia providers). The primary goal of this project is to develop an evidencebased practice guideline for …

Pharmacy Faculty Articles and Research

The human gastrointestinal system is a complex ecosystem crucial for well-being. During sepsis-induced gut injury, the integrity of the intestinal barrier can be compromised. Lipopolysaccharide (LPS), an endotoxin from Gram-negative bacteria, disrupts the intestinal barrier, contributing to inflammation and various dysfunctions. The current study explores the protective effects of limonene, a natural compound with diverse biological properties, against LPS-induced jejunal injury in mice. Oral administration of limonene at dosages of 100 and 200 mg/kg was used in the LPS mouse model. The Murine Sepsis Score (MSS) was utilized to evaluate the severity of sepsis, while serum levels of urea and …

A True Bloody Emergency: An Unusual Case Of Thrombotic Thrombocytopenic Purpura, Joshua M. Ninan

Research Symposium

Background: Thrombotic thrombocytopenic purpura (TTP) is a primary thrombotic microangiopathy that is classically characterized by thrombocytopenia and microangiopathic hemolytic anemia (MAHA). Although rare with an annual incidence of 3.7 cases per one million adults, it is considered a true hematological emergency due to its fatality rate of almost 100% if appropriate treatment is not initiated immediately. This makes it vitally important to identify and treat patients with TTP, a task that becomes unusually challenging in the absence of the disorder’s other characteristically diagnostic clinical features such as mucosal bleeding, fever, or presence of schistocytes.

Evaluation Of Nursing Approach To Assessment Of Post-Operative Respiratory Depression Using A Simulation Model, Natalia Tarasova, Usha Asirvatham, Robin D. Goetz, Mariela Riveria, Juraj Sprung, Toby N. Weingarten

Journal of Perioperative Nursing

Introduction: Assessments of post-operative patients that have been carried out by health care providers before critical opioid-induced respiratory events often do not detect respiratory depression. We hypothesise that opioidinduced respiratory patterns present during sleep may not be properly recognised as providers typically awaken patients for vital sign checks, and awake state assessment is recorded. We used a simulation manikin model to test this hypothesis.

Methods: Nurses who work on a standard post-operative hospital ward volunteered to participate in a study designed to record vital signs on an adult male manikin. None of the nurses had formal critical care or postoperative …

Ctl+Heal: A Scoping Review On Therapeutic Alliance And Technology, Vineet Sadarangani

Annual Research Symposium

A strong therapeutic alliance between a healthcare provider and patient is built upon a strong bond, trust, and open communication, all essential for successful healthcare outcomes. Establishing a robust therapeutic alliance relies significantly on non-verbal behaviors, including tone, facial expression, and eye contact. Traditionally, expert feedback was essential for addressing undesirable non-verbal behaviors and cultivating desirable ones; however, technological advancements have introduced the concept of technology-assisted feedback. This would eliminate the immediate need for experts, thus allowing the clinician more time to focus on their clinical skills; however, these methods are scattered across various fields of medical education, technology and …
