Evaluating Dosimetric Outcomes In A Prostate Rapid Plan Model: A Comparison Of Prostate Treatment Plans With And Without Standardized Planning Structures, Erica Wartman

Masters Projects

Abstract

Knowledge-based planning (KBP) using RapidPlan (RP) has demonstrated the ability to produce high quality radiation therapy treatment plans while reducing time. This study evaluated whether the inclusion of department specific standardized planning structures, including rings and other optimization tools, improves plan quality when using a prostate and lymph node RP model, or if the model alone is sufficient to provide a quality plan without the use of these additional planning structures.

Ten previously treated Prostate+LN patients were replanned using the departmental RP model in Varian Eclipse treatment planning system.1 For each patient, two plans were created, one with standardized …

Evaluating Coplanar And Noncoplanar Treatment Plans For The Varian Halcyon And Varian Truebeam For Intact Prostate Patients., Ashley Coppage

Masters Projects

Prostate cancer is among the most treated malignancies with radiation therapy, where precise dose delivery is critical for tumor control and minimizing toxicity. VMAT is widely adopted due to its efficiency and conformity; however, the choice between coplanar and non-coplanar beam arrangements remains an area of ongoing investigation, especially with newer platforms like Halcyon and TrueBeam. This retrospective dosimetric study compares coplanar and non-coplanar volumetric modulated arc therapy (VMAT) treatment plans for intact prostate cancer patients using the Varian Halcyon and Varian TrueBeam systems. Plans were created using a standardized protocol within Eclipse v16.1, with all Halcyon plans employing coplanar …

Leveraging Clinical Standards To Improve The Translational Relevance Of Therapies For Experimental Spinal Cord Injury, Aaron L. Silverstein

Theses and Dissertations--Neuroscience

Efforts to improve treatment of spinal cord injury (SCI) often use animals to develop effective therapeutics, intending to improve the survival and the quality of life of persons with SCI. Over half of all SCIs in the United States occur at the cervical level and often cause locomotor deficits and life-threatening breathing dysfunction. Thus, my dissertation is focused on this important patient population.

After beginning with a description of translational research and surveying SCI from a clinical standpoint, I turned to describe experimental models of cervical SCI and more detailed neuroimmunological findings relevant to my work. Then, I conducted a …

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.

Foley Catheter Algorithm, Chary Mathew

Doctor of Nursing Practice Projects

Urinary catheterization, indwelling and intermittent are simple and common procedures performed in hospitals, emergency rooms, nursing homes, and clinics to ensure adequate urinary output in patients who cannot void efficiently or closely monitor fluid intake and output. Though simple and straightforward in most cases, catheterization can become a challenging procedure with complications in the absence of a standardized protocol for difficult catheterization (Ghaffary et al., 2013). This Quality Improvement Project aimed to develop a standardized Foley catheter algorithm/ flow chart available in our institution's intranet and laminated charts in nursing stations and procedure rooms with Foley catheter insertion indications, types, …

Sexual Dimorphism Of Glomerular Capillary Morphology In Rats, Zackarias Coker

Undergraduate Honors Theses

Chronic kidney disease (CKD) progresses faster in males than females; however, the underlying mechanisms remain poorly understood. Sex differences in glomerular capillary morphology has been hypothesized to contribute, in part, to the increased susceptibility to hypertension-induced renal injury and CKD progression in males, but this has not been investigated. The goal of the present study was to assess glomerular capillary morphology in male vs. female rats with intact kidneys and after uninephrectomy (UNX). We hypothesized that glomerular capillary radii (R_CAP) and length (L_CAP) would be greater in male rats.

Male (n=4) and female (n=4) with intact …

Testicular Torsion Education: Improving Awareness Among Boys And Their Caregivers Regarding The Urgency Of Evaluating Scrotal Pain, Abby Taylor

Capstone Experience: Master of Public Health

Introduction: Testicular torsion is a urologic emergency that requires prompt medical evaluation and surgical intervention. The length of time from onset of the torsion to evaluation in the emergency department is often delayed due to lack of knowledge of the urgency of the situation amongst boys and their caregivers. We hypothesize that an animated educational video will increase awareness of the condition and prompt urgent evaluation in the emergency department.

Methods: A 5-minute animated educational video was created following a boy, Danny, as he develops testicular torsion. Four population groups: boys, parents, school nurses, and pediatricians, completed group-specific pre- and …

Indwelling Urinary Catheter Removal Houdini Protocol, Fatima Villacruz

Student Scholarly Projects

Practice Problem: Catheter-associated urinary tract infections (CAUTIs) in spinal cord injury (SCI) patients have many negative health consequences, including increased cost, increased length of hospital stays, delay in bladder training, increased associated infections, and mortality.

PICOT: The PICOT question that guided this project was: In adult SCI patients (P), does the implementation of a nurse-driven indwelling urinary catheter removal protocol (I), compared to without a nurse-driven protocol (C), decrease the indwelling urinary catheter days and the occurrence of CAUTIs (O) within six weeks (T)? Evidence: Nurse-driven discontinuation protocols are an effective method of decreasing indwelling urinary catheter (IUC) days and …

Expression And Function Of Transcription Factors Foxa1, Hoxb13 And Cdx2 In Prostate Cancer, Hamsat B. Anwar

University Honors Theses

Prostate cancer (PC) is the second leading cause of death in men, affecting around 190 thousand patients in 2020 alone (National Institute of Cancer, 2020). Much of the current research focuses on treatments for advanced PC, which is problematic due to the rapid evolution of tumors and development of treatment resistance. Cancer early detection presents a better approach to control and treat patients before they acquire an incurable disease. Earlier diagnosis of patients leads to better prognosis and a more comfortable treatment process (Etzioni et al., 2003). However, we currently lack molecular markers to stratify PC during its early stages. …

Methenamine Prophylaxis For Recurrent Urinary Tract Infections In A Tertiary Referral Center, Cameron A. Wade

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Purpose: Methenamine hippurate (MH) is a urinary antiseptic, indicated for prophylaxis of recurrent urinary tract infections (UTIs) but with only few and limited studies regarding its efficacy. To help address this knowledge gap we reviewed our experience with MH for UTI prophylaxis, focusing on women with recurrent uncomplicated UTIs.

Materials and Methods: The University of Kentucky electronic health record was queried to identify adults who were prescribed MH from the Urology clinic between January 2013 and January 2019. Charts were reviewed to assess patient-reported UTI frequency, demographics and relevant health factors. Treatment success was defined as 0-1 UTI in 6 …

The Role Of Ros In The Progression And Treatment Of Castration-Resistant Prostate Cancer, Dannah R. Miller

Theses & Dissertations

Prostate cancer is the second leading cause of cancer-related deaths in U.S. men, primarily due to the development of castration-resistant (CR) prostate cancer (PCa), of which there are no effective treatment options. Reactive oxygen species (ROS) plays a critical role in prostate carcinogenesis, including the progression of the CR PCa phenotype. ROS regulates both cell proliferation and apoptosis; a moderate increase in ROS can promote proliferation; however, a substantial rise in ROS levels will result in apoptosis. Oxidase p66Shc is elevated in clinical PCa cells and has been associated with a metastatic phenotype of CR PCa cells, promoting PCa cell …

Stress Urinary Incontinence In Collegiate Female Athletes: Prevalence And Impact, Marie Bouchard

Master's Projects and Capstones

Abstract

Introduction, definition: Urinary incontinence is the involuntary leaking of urine (a few drops to a few milliliters). It can happen while exercising with no urge to urinate (stress urinary incontinence), with a sudden urge to urinate (overactive bladder or urgency urinary incontinence), or a combination of the two (mixed urinary incontinence). This issue is very common among female athletes. However, because of the reluctance to discuss this problem, it remains underdiagnosed and undertreated.

Methods:An anonymous and confidential survey was distributed to the 90 University of San Francisco female student athletes from seven different varsity sports in December 2017. …

Microrna 1207-3p In Prostate Cancer, Dibash Das

Dissertations, Theses, and Capstone Projects

Prostate cancer (PCa) is the most commonly diagnosed male cancer and the second leading cause of cancer-related death for men in the United States. Understanding the molecular mechanisms involved in progression from the asymptomatic androgen-dependent PCa to the lethal castration resistant prostate cancer (CRPC) is a major challenge. MicroRNAs (miRNAs), are known to be dysregulated in PCa. MicroRNA-1207-3p (miR-1207-3p) is encoded by the non-protein coding gene locus PVT1 on the 8q24 human chromosomal region, an established PCa susceptibility locus. However, the role of miR-1207-3p in PCa is unclear. We have discovered that miR-1207-3p is significantly underexpressed in PCa cell lines …

Health Care Transition Program For Adolescents With Spina Bifida, Teresa M. Scavone

Doctor of Nursing Practice Final Manuscripts

The purpose of this evidence-based project was to evaluate the feasibility of implementing an NP facilitated formal transition program for adolescents with Spina Bifida. There is an increased awareness of the need for health care transition for youth with special health care needs (YSHCN) due to the 2009-2010 Maternal Child Health Branch National Survey findings that only 40% of YSHCN receive adequate support for transition that meets the core outcome measures. Recent studies have investigated transition in youth with chronic disease specific conditions such as diabetes, cystic fibrosis, and congenital heart defects, and provide valuable insight into possible strategies for …

Characterization Of Bacterial Pathogens Involved In Aerobic Vaginitis: Prevalence, Strain Characterization And Sequelae, Leslie A. Lafferty

Graduate School of Biomedical Sciences Theses and Dissertations

Aerobic vaginitis (AV) is a more recently defined infection that involves aerobic pathogenic bacteria that replace the normal flora of the vaginal tract. It is commonly mistaken for other vaginal infections, such as bacterial vaginosis (BV), because they share many common symptoms. AV leads to complications during pregnancy, such as premature delivery and amnion infection, and is diagnosed by indications that range from vaginal discharge to inflammation. Because this infection is difficult to diagnose differentially from other vaginal infections, it is important to determine what pathogens are involved in AV so that we may have the ability to detect them. …

Barriers Encountered By Nurses And Nursing Assistants That Prevent Purposeful Rounding, Mar Joseph B. Odias

Master's Projects and Capstones

Purpose: The aim of the study was to identify barriers encountered by registered nurses (RNs) and nursing assistants (NAs) that prevent purposeful (hourly) rounding.

Background: The literature has shown that purposeful rounding improves patient outcomes and safety. However, few studies show the barriers encountered by nursing staff that hinder the purposeful rounding process.

Methods: A pre-post test design was implemented on a 25-bed oncology, urology medical surgical unit with a staff of 38 RNs, 9 NAs, and 4 Unit Secretaries (US). A pre-implementation needs assessment survey was completed by 55% (21/38) of RNs, 33% (3/9) of NAs, and 100% (4/4) …

Mechanisms Of Therapeutic Resistance In Castration Resistant Prostate Cancer, Sarah Katherine Martin

Theses and Dissertations--Molecular and Cellular Biochemistry

Taxane based chemotherapy is an effective treatment for castration-resistant prostate cancer (CRPC) via stabilization of microtubules. Progression to castration-resistant prostate cancer is characterized by increased androgen receptor (AR), elevated intra-prostatic androgens and activated AR signaling despite castrate levels of androgens.

Previous studies identified that the inhibitory effect of microtubule targeting chemotherapy on AR activity was conferred by interfering with AR intracellular trafficking. The N-terminal domain (NTD) of AR was identified as a tubulin interacting domain that can be effectively targeted by the novel small molecular inhibitor, EPI. Taken together, this evidence provided the rationale that targeting AR nuclear translocation and …

Strategies To Sensitize Bladder Cancer Cells To Small Molecule Inhibitors Targeting The Pi3k Pathway, Giovanni Nitti

Dissertations and Theses (Open Access)

After many years of cancer research, it is well accepted by the scientific community that the future cure for this disease lies in a personalized therapeutic approach. Anticipating therapeutic outcome based on the genetic signature of a tumor has become the new paradigm. The PI3K pathway represents an ideal target for bladder cancer, as many of the key proteins of this pathway are altered or mutated in this particular type of cancer. Several small molecule inhibitors have been developed to target this pathway, but their efficacy has been shown to be heterogeneous among different cell lines and mostly cytostatic but …

The Genetic And Molecular Characterization Of The Polycystic Kidney Disease-Causing Mouse Gene Bicc1, Sarah J. Price

Theses, Dissertations and Capstones

Polycystic kidney disease (PKD) is one of the most common hereditary diseases and is characterized by progressive cyst formation, substantial renal enlargement, and frequently, progression to end-stage renal disease. One way to learn more about the etiology of this disease is to study mouse models that imitate the human situation. The juvenile congenital polycystic kidney disease (jcpk) gene on mouse Chromosome 10 has been found to cause a severe, early onset form of PKD when inherited in an autosomal recessive manner (Flaherty et al., 1995). Previous genetic studies mapped the jcpk locus to a 1 cM region on mouse Chromosome …
