Medical Student Research Symposium

INTRODUCTION AND OBJECTIVE: Ductal adenocarcinoma is considered a rare histological variant of prostate adenocarcinoma (PCa). Given the rarity of this subtype, optimal treatment strategies for men with nonmetastatic ductal PCa is largely unknown. We aimed to describe the impact of surgery, radiotherapy, and systemic therapy on overall survival (OS) in men with nonmetastatic ductal PCa.

METHODS: We retrospectively selected 2209 cases of ductal PCa, diagnosed between 2004 and 2015, within the National Cancer Database (NCDB). Exclusion of metastatic patients yielded a total sample of 1993 individuals. Cox regression analysis tested the impact of treatment (surgery, radiotherapy, systemic therapy and no ...

INTRODUCTION: End-stage kidney disease (ESKD) is a major public health problem affecting more than 2 million people worldwide. It is one of the most severe chronic non-communicable diseases. Haemodialysis (HD) is the most common therapeutic option but is also associated with a risk of cardiovascular events, hospitalisation and suboptimal quality of life. Over the past decades, haemodiafiltration (HDF) has become available. Although high-dose HDF has shown some promising survival advantage compared to conventional HD, the evidence remains controversial. A Cochrane systematic review found, in low-quality trials, with various convective forms of dialysis, a reduction in cardiovascular, but not all-cause mortality ...

Recurrent urinary tract infections (UTIs) pose a significant burden on the health care system. Underlying mechanisms predisposing children to UTIs and associated changes in the urinary proteome are not well understood. We aimed to investigate the urinary proteome of a subset of children who have vesicoureteral reflux (VUR) and recurrent UTIs because of their risk of developing infection-related renal damage. Improving diagnostic modalities to identify UTI risk factors would significantly alter the clinical management of children with VUR. We profiled the urinary proteomes of 22 VUR patients with low grade VUR (1-3 out of 5), a history of recurrent UTIs ...


The Efficacy Of Aquablation In The Treatment Of Large Volume Benign Prostatic Hypertrophy, Jessica Greenwood Jan 2020

The Efficacy Of Aquablation In The Treatment Of Large Volume Benign Prostatic Hypertrophy, Jessica Greenwood

Capstone Showcase

Introduction:

Benign Prostatic Hypertrophy (BPH) is a condition affecting adult males causing symptoms including urinary frequency, incontinence, and urinary retention. While first line treatment methods include lifestyle modifications and pharmacologic therapies, many patients elect for surgical procedures for symptomatic relief. In patients with extremely large volume prostates the surgical method most commonly used has been an open prostatectomy, which is associated with both long-term efficacy and more surgical complications than minimally invasive techniques. Therefore, this review analyzes Aquablation (I) for symptom management (O) in patients diagnosed with BPH (P) compared to open prostatectomy (C).

Methods:

A literature search was conducted ...

Chronic Recurrent Priapism: A High Flow State Secondary To An Arteriovenous Fistula Of The Corpus Cavernosum, Catherine M. Fiore, Melissa L. Pellegrino, Meghna C. Trivedi

Open Access Articles

Priapism is clinically defined as an erect penis for more than 4h unrelated to sexual stimulation. There are two main types of priapism-high flow and low flow, based on the pathophysiology. In this case report we will mainly focus on high flow, non-ischemic priapism, which is the less common form. High flow priapism occurs secondary to congenital malformation or from the development of arteriovenous malformation from genital trauma. This case highlights the importance of differentiation and recognition of posttraumatic high flow priapism and unveils the role of selective internal pudendal artery angiography and embolization in its management.

Internal Medicine

C3 glomerulonephritis (C3GN) is a rare disease that falls under the umbrella of C3 glomerulopathy. It is manifested by abnormal activation of the alternate pathway resulting in complement deposition in the glomeruli. Kidney biopsy with characteristic findings of electron-dense deposits in the mesangial and capillary wall confirms the diagnosis. Until recently, C3GN presenting with primarily lung involvement had not been reported. We present a unique case of initial pulmonary manifestation C3GN.

With the rising incidence of end-stage renal disease in the United States, patients needing renal transplants are waiting longer for increasingly scarce grafts. Formerly, the general practice was to avoid organs with tumors for transplant because of the risk of malignancy transmission to the recipient. However, with comprehensive donor selection and a small-sized primary tumor, the positive outcomes of transplant outweigh the risks of transmission after a partial nephrectomy. In our case, a 31-year-old woman, the daughter of the recipient, underwent a laparoscopic nephrectomy with an existing 8-mm tumor later confirmed as renal cell carcinoma. An ex vivo tumor enucleation ...

Lithium-Induced Chronic Kidney Disease In A Pediatric Patient, Neena Gupta, Meghan Gibson, Ellen C. Wallace

Pediatric Publications

Lithium-induced nephropathy usually manifests in adulthood as it develops slowly after many years of cumulative exposure. There is very limited information available in pediatric patients. Renal function monitoring and timely intervention is the key in preventing lithium-induced chronic kidney disease in these patients. We report a case of a 14-year-old boy who was on lithium for almost 9 years for his complex psychiatric illness. He presented with increased urinary frequency and nocturia. His serum creatinine increased to 1.15 mg/dL (estimated glomerular filtration rate or eGFR 53 ml/min/1.73 m(2)) from a baseline of 0.78 ...

Brg1 Is A Prognostic Indicator And A Potential Therapeutic Target For Prostate Cancer, Rohini Muthuswami, Leeann Bailey, Radhakrishnan Rakesh, Anthony N. Imbalzano, Jeffrey A. Nickerson, Joel W. Hockensmith

University of Massachusetts Medical School Faculty Publications

Brahma-related gene 1 (BRG1) is one of two mutually exclusive ATPases that function as the catalytic subunit of human SWItch/Sucrose NonFermentable (SWI/SNF) chromatin remodeling enzymes. BRG1 has been identified as a tumor suppressor in some cancer types but has been shown to be expressed at elevated levels, relative to normal tissue, in other cancers. Using TCGA (The Cancer Genome Atlas) prostate cancer database, we determined that BRG1 mRNA and protein expression is elevated in prostate tumors relative to normal prostate tissue. Only 3 of 491 (0.6%) sequenced tumors showed amplification of the locus or mutation in the ...


Is A Varicocelectomy Beneficial In The Era Of Assisted Reproductive Technologies, Chukwuka Oscar Nnoli Jan 2019

Is A Varicocelectomy Beneficial In The Era Of Assisted Reproductive Technologies, Chukwuka Oscar Nnoli

Physician Assistant Scholarly Project Posters

Clinical varicoceles are the most frequent physical finding associated with infertile men and impaired semen parameters. There is evidence that suggests varicocele repair improves semen parameter and increases the chances of natural pregnancy. Today, varicocele repair is often combined with assisted reproductive techniques (ART) such as intrauterine insemination (IUI), in Vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). In this literature review, data examining whether varicocelectomy before ART leads to improved pregnancy outcomes is reviewed. Current data suggest that there is a significant clinical benefit when correcting a varicocele in oligospermic men before IVF/ICSI. Similarly, men with non-obstructive azoospermia ...


Proteomic Profiling Of Serum Derived Exosomes From Prostate Cancer Patients, David Turay Oct 2018

Proteomic Profiling Of Serum Derived Exosomes From Prostate Cancer Patients, David Turay

David Turay, MD

Touted among the major achievements in the diagnosis and management of Prostate cancer (PCa) in the past few decades has been, the dramatic decline of men with advanced/metastatic PCa at diagnosis coupled with a significant improvement ( >90%) in the five and ten year survival rates of the disease. Non-palpable PCa (potentially clinically treatable disease) now accounts for 70-80% of all newly diagnosed cases of PCa. Preceding these changes by about a decade was the introduction of Prostatic Specific Antigen (PSA) into clinical practice; first as biomarker for monitoring response to therapy and subsequently as a complementary screening tool. It ...

Both Maternal And Paternal Risk Factors For Term Singleton Low Birthweight Infants In Rural Chinese Population: A Population-Based, Retrospective Cohort Study, Shi Chen, Bill Q. Lian, Hui Pan

Open Access Articles

No large population-based study has focused on both maternal paternal risk factors for low birthweight (LBW) in China. We aimed to identify parental risk factors associated with LBW. A population-based, retrospective cohort study was conducted on 202,725 singleton infants at 37-42 weeks. These term singleton newborns were classified as LBW with birthweight < /=2500 g(TLBW) and normal birthweight between 50(th) to 97(th) percentile (TNBW 50(th)-97(th)) according to Chinese singleton norms. Multiple logistic regression analyses were used to find those parental risk factors of LBW by comparing two groups. TLBW and TNBW(50(th)-97(th)) occupied 4.8% and 70.8% of the study population, respectively. Logistic regression showed a significant association with positive maternal hepatitis B surface antigen (RR = 1.979, P = 0.047), irregular folic acid intake (RR = 1.152, P = 0.003), paternal history of varicocele (RR = 2.404, P = 0.003) and female babies (RR = 1.072, P = 0.046). Maternal smoking, hypertension and history of stillbirth were found related to LBW but no statistically significant. Positive maternal hepatitis B surface antigen, irregular folic acid intake, paternal history of varicocele had a negative effect on birth weight. Measures are necessarily taken to avoid them to improve pregnancy outcomes. Further studies should be done to investigate each detailed risk factors on LBW.


Changes In The Testes Following Spinal Cord Injury And The Attenuating Effects Of Licofelone, Ryan Fortune Aug 2018

Changes In The Testes Following Spinal Cord Injury And The Attenuating Effects Of Licofelone, Ryan Fortune

The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences Dissertations and Theses (Open Access)

Spinal cord injury is a devastating disease that researchers have had very limited success in treating. In addition to interrupted innervation, spinal cord injury causes pathologic changes in a multitude of organ systems. Male infertility is one such complication that is particularly devastating because the patient population is predominantly young men. Our lab has previously shown that the blood testis barrier breaks down after spinal cord injury. This dissertation shows the local metabolomic and mRNA changes that spinal cord injury causes within the testes using a Sprague Dawley rat model, including the elevation in eicosanoids, increased oxidative stress, chronically elevated ...

Neisseria gonorrhoeae is a bacterial pathogen responsible for the sexually transmitted infection gonorrhea. Emergence of antimicrobial resistance (AMR) of N. gonorrhoeae worldwide has resulted in limited therapeutic choices for this infection. Men who seek treatment often have symptomatic urethritis; in contrast, gonococcal cervicitis in women is usually minimally symptomatic, but may progress to pelvic inflammatory disease. Previously, we reported the first analysis of gonococcal transcriptome expression determined in secretions from women with cervical infection. Here, we defined gonococcal global transcriptional responses in urethral specimens from men with symptomatic urethritis and compared these with transcriptional responses in specimens obtained from women ...

Characterization Of Human Prostate Cancer Using Sodium Magnetic Resonance Imaging, Nolan Christopher Broeke

Electronic Thesis and Dissertation Repository

Overtreatment of prostate cancer is a significant problem in the health care of men. Development of non-invasive imaging tools for improved characterization of prostate lesions has the potential to reduce overtreatment. In this thesis work, we will evaluate the ability of tissue sodium concentration obtained from sodium magnetic resonance imaging (sodium-MRI) to characterize in vivo prostate lesions. Imaging data, including multi-parametric magnetic resonance imaging (mpMRI) and sodium-MRI, were obtained from a cohort of men with biopsy-proven prostate cancer and compared to digitized whole-mount histopathology after prostatectomy. Histopathology was independently graded for Gleason score to be used as the ground truth ...


Regulation Of The Pi3-Kinase/Pten Signaling Pathway By Tgf-Β In Prostate Cancer Cells, Mawiyah Kimbrough-Allah May 2018

Regulation Of The Pi3-Kinase/Pten Signaling Pathway By Tgf-Β In Prostate Cancer Cells, Mawiyah Kimbrough-Allah

Electronic Theses & Dissertations Collection for Atlanta University & Clark Atlanta University

Transforming growth factor -β (TGF-β) plays an important role in the progression of prostate cancer. It acts as a tumor suppressor in normal epithelial cells but as a tumor promoter in advanced prostate cancer cells. The PI3-kinase pathway has been shown to play integral roles in many cellular processes including cell proliferation, survival, and cell migration in many cell types. PI3-kinase pathway mediates TGF-β effects on prostate cancer cell migration and invasion. Phosphatase and tensin homolog (PTEN), a tumor suppressor gene, inhibits PI3-kinase pathway and is frequently mutated in prostate cancers. In this present study, we investigated possible roles of ...


Elucidation Of The Functions Of Neuropilin 2 In Osteoclasts In Promoting Prostate Cancer Bone Metastasis., Navatha S. Polavaram May 2018

Elucidation Of The Functions Of Neuropilin 2 In Osteoclasts In Promoting Prostate Cancer Bone Metastasis., Navatha S. Polavaram

Theses & Dissertations

Bone metastasis is one of the major clinical concerns that causes skeletal related malignancies and increased mortality. Bone is one of the preferred sites for metastatic prostate cancer. The metastatic prostate cancer cells interact with bone cells (osteoblasts and osteoclasts) resulting in an imbalance in the bone homeostasis leading to increased activation of osteoblasts over osteoclasts. Our preliminary data indicated a non-tyrosine kinase receptor Neuropilin 2 (NRP2) is expressed in osteoclasts induced by metastatic prostate cancer cells and acts as a negative regulator of osteoclast differentiation and function. We hypothesize that prostate cancer -induced NRP2 expression in osteoclasts is necessary ...
