Sdrnas Participate In The Maintenance And Onset Of Prostate Cancer, Neil Chaudhary

Poster Presentations

What is an sdRNA? Noncoding RNA (ncRNA) is a class of RNA that includes microRNA (miRNA) and small nucleolar RNA (snoRNA). Fragments excised from ncRNAs are known as noncodingderived RNA (ndRNA). A certain class of ndRNAs that are derived from snoRNAs have been denoted as Small Nucleolar Derived RNAs (sdRNAs). Our lab has previously hypothesized and demonstrated that sdRNAs display regulatory functions on target genes, similar to the functions of miRNAs. sdRNAs are almost identical to microRNAs and differ mainly in their source of origin.

Our lab has shown that sdRNA-93 is frequently misexpressed in breast cancer cell lines and …

Radio-Histopathological Presentation And Multidisciplinary Treatment Of Adolescent Paratesticular Rhabdomyosarcoma: A Case Report, Troy Nguyen, Joseph Hatem, Abhijit Datir, Joel Thompson

Advances in Clinical Medical Research and Healthcare Delivery

Paratesticular rhabdomyosarcoma (PRMS) is a rare condition predominantly affecting the pediatric and adolescent population. In this case report, we discuss a 17-year-old male with a slow-growing, painless scrotal mass, ultimately diagnosed as embryonal PRMS — the most common and favorable rhabdomyosarcoma subtype. The report underscores the typical clinico-radiological presentation of PRMS and the pivotal part of histopathological evaluation in establishing a definitive diagnosis. Multidisciplinary intervention including surgery and chemoradiotherapy resulted in total remission. Therefore, this report underlines the significance of prompt diagnosis and comprehensive management in ensuring a favorable prognosis of PRMS.

Prostatic Utricle Presenting As A Midline Scrotal Mass, Kaitlyn E. Schultis, Bryant Van Leeuwen, John Makari

Graduate Medical Education Research Journal

The prostatic utricle is a remnant of the Müllerian duct located within the verumontanum. An enlarged, clinically significant prostatic utricle has classically been associated with hypospadias. Prostatic utricles often present with persistent lower urinary tract symptoms, recurrent infections, and urinary incontinence. We present a prostatic utricle that presented as a scrotal mass concerning for rhabdomyosarcoma in a male with normal external genitalia.

27-Hydroxycholesterol And Dna Damage Repair: Implication In Prostate Cancer, Gloria Cecilia Galvan, Nadine Friedrich, Sanjay Das, James Daniels, Sara Pollan, Shweta Dambal, Ryusuke Suzuki, Sergio Sanders, Sungyong You, Hisashi Tanaka, Yeon-Joo Lee, Wei Yuan, Johann De Bono, Irina Vasilevskaya, Karen Knudsen, Michael Freeman, Stephen Freedland

INTRODUCTION: We previously reported that cholesterol homeostasis in prostate cancer (PC) is regulated by 27-hydroxycholesterol (27HC) and that CYP27A1, the enzyme that converts cholesterol to 27HC, is frequently lost in PCs. We observed that restoring the CYP27A1/27HC axis inhibited PC growth. In this study, we investigated the mechanism of 27HC-mediated anti-PC effects.

METHODS: We employed in vitro models and human transcriptomics data to investigate 27HC mechanism of action in PC. LNCaP (AR+) and DU145 (AR-) cells were treated with 27HC or vehicle. Transcriptome profiling was performed using the Affymetrix GeneChip™ microarray system. Differential expression was determined, and gene set enrichment …

Intensity Modulated Radiation Therapy With Stereotactic Body Radiation Therapy Boost For Unfavorable Prostate Cancer: Five-Year Outcomes, Michael Carrasquilla, Tamir Sholklapper, Abigail Pepin, Nicole Hodgins, Siyuan Lei, Abdul Rashid, Malika Danner, Alan Zwart, Grecia Bolanos, Marilyn Ayoob, Thomas Yung, Nima Aghdam, Brian Collins, Simeng Suy, Deepak Kumar, Ryan Hankins, Keith Kowalczyk, Nancy Dawson, Sean Collins

Einstein Health Papers

PURPOSE: Intensity-modulated radiation therapy (IMRT) with brachytherapy boost for unfavorable prostate cancer has been shown to improve biochemical relapse-free survival compared to IMRT alone. Stereotactic body radiation therapy (SBRT) is a less-invasive alternative to brachytherapy. Early outcomes utilizing SBRT boost suggest low rates of high-grade toxicity with a maintained patient-reported quality of life. Here, we report the 5-year progression-free survival (PFS) and prostate cancer-specific survival (PCSS) of patients treated with IMRT plus SBRT boost.

MATERIALS AND METHODS: Between 2008 and 2020, 255 patients with unfavorable prostate cancer were treated with robotic SBRT (19.5 Gy in three fractions) followed by fiducial-guided …

To Screen Or Not To Screen: Prostate Cancer In Liver Transplant Candidates, Patrick Twohig, Jared Schober, Timothy Mccashland, Thoetchai Peeraphatdit

Graduate Medical Education Research Journal

Prostate cancer screening is a controversial topic in the general population and is even more contested among liver transplant candidates. Not only should transplant programs be concerned about the risk of false positive screening results but also the competing risks of death and the diagnostic and therapeutic effects of true prostate cancer, which often does not cause significant morbidity or mortality in organ transplant recipients. Our letter highlights a best-practices approach to prostate cancer screening in transplant candidates using available research and consensus guidelines.

Penile Calciphylaxis In An End Stage Renal Disease Patient., Juan Enrique Garcia Lopez, Alain Velazquez Blanco, Aileen Aguilar, Sareena Siyas, Daniel Ibarias Paz, Mays Abdulazeez, Jesus Garza-Tamez, Desmond Adamu

Research Colloquium

Background: Penile Calciphylaxis occurs in about 1–4% of hemodialysis patients worldwide. Associated mortality rates are very high, and hyperparathyroidism is the second most frequently associated disorder. Addressing the resulting metabolic imbalance, and surgical intervention guided by findings of radiological studies may improve quality of life. The pathogenesis is thought to be mediated by vascular smooth muscle cells which differentiate into osteoblast-like cells. Decrease in vascular calcification inhibitory proteins fetuin-A and matrix Gla is found in patients on dialysis causing systemic medial calcification of arterioles, leading to epidermal ischemia, tissue infarction, and ulceration.

Case presentation: 47-year-old male with history of coronary …

Characterization Of Prostate Cancer In Transgender Women, Simita Gaglani, Rajveer Purohit, Ashutosh Tewari, Dara Lundon, Natasha Kyprianou

Research Symposium

Background: The risk of developing prostate cancer (PC) in transgender women is unknown. Many patients are unaware that the prostate is not removed during male-to-female surgical transition. It is unclear what the exposure of estrogens and androgen blockers in these transgender patients has on the prostate. Our aim was to examine and characterize the different presentations of PC in published cases and augment this with an additional case series from one institute.

Methods: A retrospective review of prospectively maintained medical records was performed identifying features of PC diagnoses in transgender women. These included age, duration of feminizing hormone therapy, PSA …

Outpatient Sexually Transmitted Infection Testing And Treatment Patterns In The United States: A Real-World Database Study, Rebecca Lillis, Louis Kuritzky, Zune Huynh, Rodney Arcenas, Avneet Hansra, Roma Shah, Baiyu Yang, Stephanie N. Taylor

School of Medicine Faculty Publications

Background: Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) are the most common notifiable sexually transmitted infections (STIs) in the United States. Because symptoms of these infections often overlap with other urogenital infections, misdiagnosis and incorrect treatment can occur unless appropriate STI diagnostic testing is performed in clinical settings. The objective of this study was to describe STI diagnostic testing and antimicrobial treatment patterns and trends among adolescent and adult men and women with lower genitourinary tract symptoms (LGUTS). Methods: We analyzed insurance claims data from the IBM® MarketScan® Research Databases. Patients included were between 14 and 64 years old with …

Encouraging Human Papillomavirus Vaccine Uptake: A Healthcare Improvement Project, Lauren E. Woll

Dissertations

Abstract

Problem: Human papillomaviruses are the causative agents of >95% of cervical cancers, most oropharyngeal and anogenital cancers, yet the vaccination status of the population remains critically low despite Gardasil9 offering robust protection against HPV-related disease.

Methods: This quality improvement project utilized a descriptive, observational design to assess the effect of the HPV Encouragement Bundle, a two-step intervention to improve HPV vaccine uptake. Quantitative data was collected via retrospective chart review to assess the effect of the intervention on first-dose administration of Gardasil9 (series initiation), as well as overall Gardasil9 vaccine uptake.

Results: Following implementation, Gardasil9 first dose uptake increased …

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 …

An Exceedingly Rare Case Of Bilateral Synchronous Germ Cell Testicular Tumors Of Different Histological Types, Joseph Kim, Ray Page, Gregory Moses, Rod Carlo Columbres

North Texas Research Forum 2023

It is exceedingly rare to find a case of bilateral synchronous germ cell testicular tumors of different histological types, and there have been only a handful of cases because of a lack of connections through lymphatic or vascular pathways between the testes. Here we present a unique case of a 43-year-old man who initially presented to the primary care physician for increasing right testicular swelling. He had a testicular sonogram that showed a large right testicular mass as well as a 1.7 cm left testicular mass suspicious of malignancy. Pre-surgical laboratories showed PSA 0.97, alpha-fetoprotein 1875, quantitative hCG 2508, and …

Switch-Like Behavior Of Lysosomes And Vcp Supports Spermatocyte Health And Development In Drosophila, Tyler James Butsch

LSU Doctoral Dissertations

Changes to societal norms, such as the educational, marital, and child-bearing expectations have coincided with significant increases in infertility worldwide. Surprisingly, male infertility is responsible for approximately half of all infertility cases worldwide. Thus, a better understanding of sperm development, and how it is affected by age, may permit the design and application of therapeutics to treat various cases male infertility. Here, I have found that lysosomes acidify as germ cells enter the spermatocyte stage. Once active, lysosomes turn over E-cadherin, and likely other proteins, to support plasma membrane stability. Notably, aging negatively impacts lysosome acidification, which can be reversed …

Background: Squamous cell carcinoma of the anus (SCCA) is a rare gastrointestinal cancer. Factors associated with progression of HPV infection to anal dysplasia and cancer are unclear and screening guidelines and approaches for anal dysplasia are less clear than for cervical dysplasia. One potential contributing factor is the anorectal microbiome. In this study, we aimed to identify differences in anal microbiome composition in the settings of HPV infection, anal dysplasia, and anal cancer in this rare disease. Methods: Patients were enrolled in two prospective studies. Patients with anal dysplasia were part of a cross-sectional cohort that enrolled women with high-grade …

Evaluating The Role Of Lvi As An Indicator For Adverse Outcomes In Patients With Upper Tract Urothelial Carcinoma And Its Histological Subtypes, Ivan Rakic, Matthew Davis, Nicholas Corsi, Alexander Stephens, Chase Morrison, Sohrab Arora, Taylor Malchow, Akshay Sood, Craig Rogers, Firas Abdollah

Medical Student Research Symposium

Lymphvascular invasion (LVI) is recognized as an adverse prognostic factor in many cancers. Our aim is to assess the prognostic ability of LVI in UTUC urothelial carcinoma (UC) and micropapillary urothelial carcinoma (MPUC) subtypes as a predictor of overall survival (OS) using a large North American cohort.

Our cohort included 9750 cM0 UTUC patients who underwent a radical nephroureterectomy (RNU), between 2004 and 2015, within the National Cancer Database (NCDB). The main variable of interest was LVI status, and its interaction with pathological nodal (pN) status. Kaplan-Meier curves were used to estimate the OS. Cox regression analysis tested the impact …

Fontham, Alan Diekman, Lora J. Rogers, Calvin T. Ratliff, Jeannette T. Bensen, James L. Mohler, L. Joseph Su

School of Public Health Faculty Publications

Background: Studies showed that folate and related single nucleotide polymorphisms (SNPs) could predict prostate cancer (PCa) risk. However, little is known about the interactions of folate-related SNPs associated with PCa aggressiveness. The study’s objective is to evaluate SNP–SNP interactions among the DHFR 19-bp polymorphism and 10 SNPs in folate metabolism and the one-carbon metabolism pathway associated with PCa aggressiveness. Methods: We evaluated 1294 PCa patients, including 690 European Americans (EAs) and 604 African Americans (AAs). Both individual SNP effects and pairwise SNP–SNP interactions were analyzed. Results: None of the 11 individual polymorphisms were significant for EAs and AAs. Three SNP–SNP …

Bundle Up To Improve Cauti, Jennifer Anderson, Valorie Dearmon

DNP Manuscripts

Catheter Associated Urinary Tract Infections (CAUTIs) are a leading cause of healthcare acquired infections. Strong evidence for CAUTI best practices exists, however, the struggle to translate best practice evidence into everyday practice remains a challenge. Catheter associated urinary tract infection rates continue to be a problem despite organizational efforts to implement best practice guidelines; the challenge is to effectively translate and embed best practices into everyday practice. The Centers for Medicare and Medicaid Services (CMS) will no longer reimburse hospitals for expenses associated with hospital acquired CAUTI; moreover, hospitals are subject to penalties for high rates of hospital acquired CAUTIs. …
