"I was in a very deep, dark place... I wasn't prepared for that": A qualitative assessment of the emotional well-being needs of patients undergoing cystectomy.

Introduction: Studies have shown that cystectomy has a large psychological burden on patients with bladder cancer. However, there has been little work characterizing areas of improvement. This project aimed to understand cystectomy patients' experiences and to identify patient-centered methods to improve perioperative support.

Plasma-Induced Graft Polymerization for the In Situ Synthesis of Cross-Linked Nanocoatings.

Conventional technology for the modification of surfaces loaded with nanomaterials typically requires a three-step process: (1) the construction of a polymer platform, (2) the synthesis of nanoparticles (NPs), and (3) the immobilization or anchoring of NPs. During the immobilization or anchoring process, there is an unavoidable excess of NPs primarily situated at the top of the surface, resulting in the agglomeration of aggregates. These aggregates can form different shapes and sizes, often creating an uneven distribution of NPs, resulting in an unstable coating that gradually releases NPs over time.

"…I Wish Someone Told Me About That…": A Qualitative Assessment of the Educational Needs of Patients Undergoing Cystectomy.

Objective: To utilize patient feedback to identify areas of need for information and ways to improve delivery of education, due to recognition that cystectomy and urinary diversion is a complex operation often overwhelming patients and caregivers.

Methods: We conducted 5 focus groups of bladder cancer patients (separated by gender and diversion type) treated with cystectomy and urinary diversion (n = 17). Questions focused on areas of improvement for patient education.

Comparison of Work Relative Value Units Assigned to Urological and Gynecological Surgical Procedures.

Introduction: We sought to determine if work relative value unit differences exist between analogous, sex-specific procedures.

Methods: Representatives from the AUA and the American College of Obstetricians and Gynecologists independently reviewed the entire procedural code set and identified sex-specific procedures that had an analogous procedure in the opposite sex. These pairs were then evaluated and compared using current American Medical Association Relative Value Scale Update Committee methodology.

Application of Argon Plasma Technology for the Synthesis of Anti-Infective Copper Nanoparticles.

The synthesis of copper nanoparticles (CuNPs) was accomplished by using a rapid, green, and versatile argon plasma reduction method that involves solvent extraction. With this method, a plasma-solid state interaction forms and CuNPs can be synthesized from copper(II) sulfate using a low-pressure, low-temperature argon plasma. Characterization studies of the CuNPs revealed that when a metal precursor is treated under optimal experimental conditions of 80 W of argon plasma for 300 s, brown CuNPs are synthesized.

Shorter Ureters Lead to Fewer Strictures Following Cystectomy and Urinary Diversion.

Objective: To identify the impact of length of distal ureteral resection on the risk of benign uretero-enteric anastomotic stricture (UEAS) formation following cystectomy and urinary diversion.

Methods: A database of patients who underwent cystectomy and urinary diversion from 2015 to 2022 was analyzed. Distal ureteral resections were sent for final pathology.

Impact of Agent Orange Exposure on Non-muscle Invasive Bladder Cancer Outcomes.

Objective: To explore the effect of Agent Orange (AO) exposure on bladder cancer (BCa) outcomes in patients receiving Bacillus Calmette-Guérin (BCG) for non-muscle invasive BCa (NMIBC).

Methods: We retrospectively examined the association between AO exposure in patients with NMIBC in national veterans affairs databases who were being treated with BCG. Patients were diagnosed with NMIBC from 2000 to 2010 with follow-up through 2018.

Lipid biosynthesis perturbation impairs endoplasmic reticulum-associated degradation.

The relationship between lipid homeostasis and protein homeostasis (proteostasis) is complex and remains incompletely understood. We conducted a screen for genes required for efficient degradation of Deg1-Sec62, a model aberrant translocon-associated substrate of the endoplasmic reticulum (ER) ubiquitin ligase Hrd1, in Saccharomyces cerevisiae. This screen revealed that INO4 is required for efficient Deg1-Sec62 degradation.

Gender and Racial Diversity among U.S. Urology Residency Programs and Efforts to Improve It: You Can't Be What You Can't See.

Introduction: The U.S. urology workforce lacks ethnic and gender diversity.

NCCN Guidelines® Insights: Bladder Cancer, Version 2.2022.

The NCCN Guidelines for Bladder Cancer provide recommendations for the diagnosis, evaluation, treatment, and follow-up of patients with bladder cancer and other urinary tract cancers (upper tract tumors, urothelial carcinoma of the prostate, primary carcinoma of the urethra). These NCCN Guidelines Insights summarize the panel discussion behind recent important updates to the guidelines regarding the treatment of non-muscle-invasive bladder cancer, including how to treat in the event of a bacillus Calmette-Guérin (BCG) shortage; new roles for immune checkpoint inhibitors in non-muscle invasive, muscle-invasive, and metastatic bladder cancer; and the addition of antibody-drug conjugates for metastatic bladder cancer.

Epitaxial Growth of a Thin Layer of Putative Cancer Cells under Limited Resources and in the Presence of an Alkylating Agent.

The dynamics of the Eden cluster in a 32x32 lattice is implemented using a stochastic model. A single-type of cells solid tumor is assumed. Duplication is probabilistic, and occurs when there is room in the immediate surroundings of a cell, otherwise the cell is inhibited by contact.

Epigenetic field alterations in non-tumor prostate tissues detect prostate cancer in urine.

Prostate cancer (PC) development involves epigenetic DNA methylation changes that occur in the tumor. However, distinct DNA methylation changes have been previously found to encompass a widespread cancer field defect involving normal prostate tissue. In the current study, we analyzed a series of DNA methylation field markers to determine if they predict the presence of PC in urine.

Clinicopathological Criteria Predictive of Recurrence Following Bacillus Calmette-Guérin Therapy Initiation in Non-Muscle-Invasive Bladder Cancer: Retrospective Cohort Study.

Background: Bacillus Calmette-Guérin (BCG) is currently the most clinically effective intravesical treatment for non-muscle-invasive bladder cancer (NMIBC), particularly for patients with high-risk NMIBC such as those with carcinoma in situ. BCG treatments could be optimized to improve patient safety and conserve supply by predicting BCG efficacy based on tumor characteristics or clinicopathological criteria.

Objective: The aim of this study is to assess the ability of specific clinicopathological criteria to predict tumor recurrence in patients with NMIBC who received BCG therapy along various treatment timelines.

Inner Nuclear Membrane Asi Ubiquitin Ligase Catalytic Subunits Asi1p and Asi3p, but not Asi2p, confer resistance to aminoglycoside hygromycin B in .

The heterotrimeric Asi ubiquitin ligase (encoded by , , and ) mediates protein degradation in the inner nuclear membrane in . Asi1p and Asi3p possess catalytic domains, while Asi2p functions as an adaptor for a subset of Asi substrates. We hypothesized the Asi complex is an important mediator of protein quality control, and we predicted that Asi would be required for optimal growth in conditions associated with elevated abundance of aberrant proteins.

Transrectal ultrasound guided prostate biopsy performed by supervised junior and senior residents is safe and does not result in inferior outcomes.

Purpose: To compare transrectal ultrasound guided prostate biopsy (TRUSBx) cancer detection and complication rates between residents at different levels of training and attending physicians at a single academic center.

Methods: We performed a retrospective review of consecutive series of 623 men undergoing TRUSBx from June 2014 to February 2017. The procedure was performed either by resident physicians under direct supervision by an attending physician or by an attending physician.

Beta-Adrenergic Antagonists and Cancer Specific Survival in Patients With Advanced Prostate Cancer: A Veterans Administration Cohort Study.

Objective: To interrogate the National Veterans Health Administration (VA) database to determine if beta-blocker use at time of initiation of androgen therapy deprivation (ADT) would result in improved oncological outcomes in advanced prostate cancer (PCa).

Methods: All men diagnosed with high risk PCa (PSA >20) from 2000-2008 who were on ADT ≥ 6 months were identified. Patients receiving ADT concurrently with primary radiation therapy were excluded.

Overlapping function of Hrd1 and Ste24 in translocon quality control provides robust channel surveillance.

Translocation of proteins across biological membranes is essential for life. Proteins that clog the endoplasmic reticulum (ER) translocon prevent the movement of other proteins into the ER. Eukaryotes have multiple translocon quality control (TQC) mechanisms to detect and destroy proteins that persistently engage the translocon.

Synthetic Lethal Metabolic Targeting of Androgen-Deprived Prostate Cancer Cells with Metformin.

The initiation of androgen-deprivation therapy (ADT) induces susceptibilities in prostate cancer cells that make them vulnerable to synergistic treatment and enhanced cell death. Senescence results in cell-cycle arrest, but cells remain viable. In this study, we investigated the mechanisms by which prostate cancer cells undergo senescence in response to ADT, and determined whether an FDA-approved antidiabetic drug metformin has a synergistic effect with ADT in prostate cancer both and Our results show that longer term exposure to ADT induced senescence associated with p16 and/or p27 induction.

Increased Bacillus Calmette-Guérin Treatment Intensity Associated With Improved Outcomes in Elderly Patients With Non-Muscle-invasive Bladder Cancer in United States Clinical Practice.

Objective: To characterize Bacillus Calmette-Guérin (BCG) treatment patterns and associated outcomes in a large cohort of patients with non-muscle-invasive bladder cancer (NMIBC).

Methods: Our retrospective analysis of patients aged ≥66 years with stage 0-1 urothelial bladder carcinoma diagnosed between 2000 and 2012 in the United States Surveillance, Epidemiology, and End Results-Medicare database estimated proxies for recurrence and secondary events and both all-cause and bladder cancer-specific mortality. Proportional hazards models were used in conditional landmark analyses to compare adequate (≥5 induction instillations and ≥2 maintenance instillations) and inadequate BCG, stratified by National Comprehensive Cancer Network risk group.

Trends in epidural anesthesia use at the time of radical cystectomy and its association with perioperative and survival outcomes: a population-based analysis.

Epidural anesthesia is used to improve pain control after major surgeries. Few data describe the impact of epidural use for bladder cancer patients treated with radical cystectomy (RC). Here, we evaluate epidural use on perioperative and long-term outcomes for patients treated with radical cystectomy for bladder cancer.

Comparing Outcomes for Patients with Clinical T1b Renal Cell Carcinoma Treated With Either Percutaneous Microwave Ablation or Surgery.

Objective: To compare perioperative and oncologic outcomes for patients with clinical T1b renal cell carcinoma following treatment with microwave ablation (MW), partial nephrectomy (PN), or radical nephrectomy (RN).

Methods: Comprehensive clinical and pathologic data were collected for nonmetastatic renal cell carcinoma patients with cT1b tumors following MW, PN, or RN from 2000 to 2018. Local recurrence-free, metastasis-free, cancer-specific and overall survival were estimated using Kaplan-Meier method.
