Role of Gut Microbiome in Neoadjuvant Chemotherapy Response in Urothelial Carcinoma: A Multi-institutional Prospective Cohort Evaluation.

Neoadjuvant chemotherapy (NAC) is linked with clinical advantages in urothelial carcinoma for patients with muscle-invasive bladder cancer (MIBC). Despite comprehensive research into the influence of tumor mutation expression profiles and clinicopathologic factors on chemotherapy response, the role of the gut microbiome (GM) in bladder cancer chemotherapy response remains poorly understood. This study examines the variance in the GM of patients with bladder cancer compared with healthy adults, and investigates GM compositional differences between patients who respond to chemotherapy versus those who exhibit residual disease.Our study reveals distinct clustering, effectively separating the bladder cancer and healthy cohorts. However, no significant differences were observed between chemotherapy responders and nonresponders within community subgroups. Machine learning models based on responder status outperformed clinical variables in predicting complete response (AUC 0.88 vs. AUC 0.50), although no single microbial species emerged as a fully reliable biomarker.The evaluation of short chain fatty acid (SCFA) concentration in blood and stool revealed no correlation with responder status. Still, SCFA analysis showed a higher abundance of Akkermansia (rs = 0.51, P = 0.017) and Clostridia (rs = 0.52, P = 0.018), which correlated with increased levels of detectable fecal isobutyric acid. Higher levels of fecal Lactobacillus (rs = 0.49, P = 0.02) and Enterobacteriaceae (rs = 0.52, P < 0.03) correlated with increased fecal propionic acid.In conclusion, our study constitutes the first large-scale, multicenter assessment of GM composition, suggesting the potential for a complex microbial signature to predict patients more likely to respond to NAC based on multiple taxa. SIGNIFICANCE: Our study highlights results that link the composition of the GM to the efficacy of NAC in MIBC. We discovered that patients with higher levels of Bacteroides experienced a worse response to NAC. This microbial signature shows promise as a superior predictor of treatment response over traditional clinical variables. Although preliminary, our findings advocate for larger, more detailed studies to validate these associations.

Population Estimates of Ovarian Cancer Risk in a Cohort of Patients with Bladder Cancer.

BACKGROUND AND OBJECTIVE: The rationale for oophorectomy during female cystectomy is not adequately supported. The co-occurrence and timing of bladder cancer (BC) and ovarian cancer (OC) in females harboring OC germline mutations remain unclear. Our objective was to determine the frequency and temporal occurrence of OC germline variants among females with BC. METHODS: We used genetic and phenotypic data from the UK Biobank (UKB). The study cohort was defined using ICD-10/ICD-9 codes for BC and further stratified to identify 1347 females. Analysis was restricted to variants with high/moderate impact for initial regression. ClinVar was used to interpret pathogenicity. Pathogenic/likely pathogenic (P/LP) variants were assessed by age of presentation, family history, and concomitant malignancies. Statistical analysis was performed using UKB DNAnexus JupyterLab and RStudio. KEY FINDINGS AND LIMITATIONS: Some 3.4% of the patients had at least one of 15 variants for OC. CHEK2 and PALB2 mutations represented the highest ratio of overall/pathogenic variants (15.8% and 6.6%). Although females with P/LP OC mutations had a higher risk of OC, diagnosis of OC preceded BC by 11.3 yr (±12.5 yr) in the group with mutations and by 15.6 yr (±11.3 yr) in the group without mutations. The group with P/LP variants had higher rates of maternal (14.63% vs 8.12%; p = 0.04) and sibling (9.76% vs 3.98%; p = 0.02) breast cancer and of maternal colon cancer (9.76% vs 4.21%), and lower maternal life expectancy (75.34 vs 68.15 yr; p = 0.0014). UKB provides limited staging/treatment history and its exome sequencing platform may miss variants or provide insufficient coverage for genotyping. CONCLUSIONS AND CLINICAL IMPLICATIONS: This study provides evidence against routine oophorectomy for reducing OC risk in females with BC. The results highlight that the development of OC occurred 11 yr before diagnosis of BC for patients with OC mutations and 15 yr before diagnosis of BC for patients without OC mutations. PATIENT SUMMARY: Although removal of the ovaries in women with bladder cancer is common, no studies have shown that this strategy has a benefit. Our study of women diagnosed with bladder cancer who had genetic mutations associated with ovarian cancer shows that their risk of developing ovarian cancer after bladder cancer is low. These findings provide evidence against removal of the ovaries when the bladder is being removed as treatment for bladder cancer.

Female sexual function evaluation and intraoperative vaginal reconstruction in bladder cancer.

RC significantly negatively impacts sexual function (SF) in both men and women. While significant research resources have been allocated to examine the deleterious effects of post prostatectomy erectile dysfunction, little attention has been directed towards female sexual function and organ preservation post cystectomy. These academic shortcomings often result in poor provider awareness and inadequate preoperative assessment. As such, it is crucial for all providers involved in female RC care to understand the necessary and available tools for preoperative evaluation, in addition to the anatomic and reconstructive techniques. This review aims to summarize the current preoperative evaluation and available tools of SF assessment and describe in detail the varying operative techniques in the preservation or restoration of SF in women after RC. The review explores the intricacies of preoperative evaluation tools, and intraoperative techniques for organ- and nerve-sparing during radical cystectomy in females. Particular emphasis on vaginal reconstruction after partial or complete resection is provided, including split-thickness skin (STF) graft vaginoplasy, pedicled flaps, myocutaneous flaps and use of bowel segments. In conclusion, this narrative review highlights the importance of understanding anatomic considerations and nerve-sparing strategies in promoting postoperative SF and quality of life. Furthermore, the review describes the advantages and limitations of each organ- and nerve-sparing technique and their impact on sexual function and overall well-being.

Bladder and Kidney Cancer Diagnosis and Survival Increase With Medicare Eligibility at Age 65.

INTRODUCTION: Medicare eligibility at 65 has been associated with increased diagnosis and survival for certain cancers due to greater health care utilization. We aim to assess for a similar "Medicare effect" for bladder and kidney cancers, which has not been previously established. METHODS: Patients diagnosed with bladder or kidney cancer from 2000-2018 at ages 60-69 years were identified with the Surveillance, Epidemiology, and End Results database. We used age-over-age percent change calculations to characterize trends in cancer diagnoses focusing on patients aged 65. Multivariable Cox models were used to compare cancer-specific mortality across ages at diagnosis. RESULTS: We identified 63,960 patients diagnosed with bladder cancer and 52,316 diagnosed with kidney cancer. Age-over-age change in diagnosis was highest for patients aged 65 compared to all other ages for both cancers (P < .01 for both). Stratified by stage, patients aged 65 had a higher age-over-age change than those aged 61-64 or 66-69 for in situ (P = .01, P < .01, respectively), localized (P = .03, P = .01), and regional (P = .02, P = .02) bladder cancer and localized (P = .01, P = .01) kidney cancer. Bladder cancer patients aged 65 had lower cancer-specific mortality than patients aged 66 (HR = 1.17, P = .01) and 69 (HR = 1.18, P = .01), while kidney cancer patients aged 65 had lower mortality than patients aged 64 (HR = 1.18, P < .01) and 66-69. CONCLUSIONS: The age of 65, marking the onset of Medicare eligibility, is associated with more diagnoses of bladder and kidney cancer. Patients diagnosed at age 65 demonstrate decreased bladder and kidney cancer-specific mortality.

Cost-effectiveness analysis of arterial catheter insertion on robotic-assisted laparoscopic prostatectomy.

INTRODUCTION: To evaluate the utility, outcomes, and cost of arterial line placement in a single institution cohort of patients undergoing robotic-assisted laparoscopic prostatectomy (RALP). MATERIALS AND METHODS: A retrospective chart review was performed at a large tertiary care center from July 2018 through January 2021. Hospital costs and cost-effective analysis was performed on patients with and without arterial line placement. Means with standard deviations were used to report continuous variables, while numbers and percentages were utilized to describe categorical variables. T-tests and Chi-square tests compared categorical and continuous variables across study cohorts, respectively. Multivariable analyses were used to examine the association between A-line placement and outcomes as mentioned above adjusting for the effect of other co-variables. RESULTS: Among the 296 included patients, 138 (46.6%) had arterial lines. No preoperative patient characteristic predicted arterial line placement. Rates of complications and re-admissions were not statistically significant between the two groups. Arterial line use was associated with higher volumes of intraoperative fluid administration, as well as a longer hospital length of stay. Total cost and operative time did not significantly differ between cohorts, but arterial line placement increased variability of these factors. CONCLUSION: The use of arterial lines in patients undergoing RALP is not necessarily guideline-driven and does not decrease the rate of perioperative complications. However, it is associated with longer length of stay and increases variability in charge. These data show that the surgical team and anesthesia team should critically evaluate the need for arterial line placement in patients undergoing RALP.

Disparities in cause-specific mortality by race and sex among bladder cancer patients from the SEER database.

PURPOSE: Previous literature shows that more bladder cancer patients overall die from causes other than the primary malignancy. Given known disparities in bladder cancer outcomes by race and sex, we aimed to characterize differences in cause-specific mortality for bladder cancer patients by these demographics. METHODS: We identified 215,252 bladder cancer patients diagnosed with bladder cancer from 2000 to 2017 in the SEER 18 database. We calculated cumulative incidence of death from seven causes (bladder cancer, COPD, diabetes, heart disease, external, other cancer, other) to assess differences in cause-specific mortality between race and sex subgroups. We used multivariable Cox proportional hazards regression and Fine-Gray competing risk models to compare risk of bladder cancer-specific mortality between race and sex subgroups overall and stratified by cancer stage. RESULTS: 17% of patients died from bladder cancer (n = 36,923), 30% died from other causes (n = 65,076), and 53% were alive (n = 113,253). Among those who died, the most common cause of death was bladder cancer, followed by other cancer and diseases of the heart. All race-sex subgroups were more likely than white men to die from bladder cancer. Compared to white men, white women (HR: 1.20, 95% CI: 1.17-1.23) and Black women (HR: 1.57, 95% CI: 1.49-1.66) had a higher risk of dying from bladder cancer, overall and stratified by stage. CONCLUSION: Among bladder cancer patients, death from other causes especially other cancer and heart disease contributed a large proportion of mortality. We found differences in cause-specific mortality by race-sex subgroups, with Black women having a particularly high risk of dying from bladder cancer.

Global Meta-analysis of Urine Microbiome: Colonization of Polycyclic Aromatic Hydrocarbon-degrading Bacteria Among Bladder Cancer Patients.

BACKGROUND: The application of next-generation sequencing techniques has enabled characterization of urinary tract microbiome. Although many studies have demonstrated associations between the human microbiome and bladder cancer (BC), these have not always reported consistent results, thereby necessitating cross-study comparisons. Thus, the fundamental questions remain how we can utilize this knowledge. OBJECTIVE: The aim of our study was to examine the disease-associated changes in urine microbiome communities globally utilizing a machine learning algorithm. DESIGN, SETTING, AND PARTICIPANTS: Raw FASTQ files were downloaded for the three published studies in urinary microbiome in BC patients, in addition to our own prospectively collected cohort. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Demultiplexing and classification were performed using the QIIME 2020.8 platform. De novo operational taxonomic units were clustered using the uCLUST algorithm and defined by 97% sequence similarity and classified at the phylum level against the Silva RNA sequence database. The metadata available from the three studies included were used to evaluate the differential abundance between BC patients and controls via a random-effect meta-analysis using the metagen R function. A machine learning analysis was performed using the SIAMCAT R package. RESULTS AND LIMITATIONS: Our study includes 129 BC urine and 60 healthy control samples across four different countries. We identified a total of 97/548 genera to be differentially abundant in the BC urine microbiome compared with that of healthy patients. Overall, while the differences in diversity metrics were clustered around the country of origin (Kruskal-Wallis, p < 0.001), collection methodology was a driver of microbiome composition. When assessing dataset from China, Hungary, and Croatia, data demonstrated no discrimination capacity to distinguish between BC patients and healthy adults (area under the curve [AUC] 0.577). However, inclusion of samples with catheterized urine improved the diagnostic accuracy of prediction for BC to AUC 0.995, with precision-recall AUC = 0.994. Through elimination of contaminants associated with the collection methodology among all cohorts, our study identified increased abundance of polycyclic aromatic hydrocarbon (PAH)-degrading bacteria Sphingomonas, Acinetobacter, Micrococcus, Pseudomonas, and Ralstonia to be consistently present in BC patients. CONCLUSIONS: The microbiota of the BC population may be a reflection of PAH exposure from smoking, environmental pollutants, and ingestion. Presence of PAHs in the urine of BC patients may allow for a unique metabolic niche and provide necessary metabolic resources where other bacteria are not able to flourish. Furthermore, we found that while compositional differences are associated with geography more than with disease, many are driven by the collection methodology. PATIENT SUMMARY: The goal of our study was to compare the urine microbiome of bladder cancer patients with that of healthy controls and evaluate any potential bacteria that may be more likely to be found in patients with bladder cancer. Our study is unique as it evaluates this across multiple countries, to find a common pattern. After we removed some of the contamination, we were able to localize several key bacteria that are more likely to be found in the urine of bladder cancer patients. These bacteria all share their ability to break down tobacco carcinogens.

Role of Gut Microbiome in Neoadjuvant Chemotherapy Response in Urothelial Carcinoma: A Multi-Institutional Prospective Cohort Evaluation.

Treatment with neoadjuvant chemotherapy (NAC) in muscle invasive bladder cancer (MIBC) is associated with clinical benefit in urothelial carcinoma. While extensive research evaluating role of tumor mutational expression profiles and clinicopathologic factors into chemoresponse has been published, the role of gut microbiome (GM) in bladder cancer in chemoresponse has not been thoroughly evaluated. A working knowledge of the microbiome and its effect on all forms of cancer therapy in BC is critical. Here we examine gut microbiome of bladder cancer patients undergoing NAC. Overall, there was no significant difference in alpha and beta diversity by responder status. However, analysis of fecal microbiome samples showed that a higher abundance of Bacteroides within both institutional cohorts during NAC was associated with residual disease at the time of radical cystectomy regardless of chemotherapy regimen. Group community analysis revealed presence of favorable microbial subtypes in complete responders. Finally, fecal microbial composition outperformed clinical variables in prediction of complete response (AUC 0.88 vs AUC 0.50), however, no single microbial species could be regarded as a fully consistent biomarker. Microbiome-based community signature as compared to single microbial species is more likely to be associated as the link between bacterial composition and NAC response.

National Adherence to Guidelines for Antimicrobial Prophylaxis for Patients Undergoing Radical Cystectomy.

PURPOSE: The sentinel reference for antibiotic prophylaxis for radical cystectomy with ileal conduit in the AUA Guidelines reports data from 2003-2013 and has not been updated in the interim. Here, we assess adherence to antibiotic prophylaxis guidelines among patients undergoing radical cystectomy with ileal conduit for bladder cancer using a large national database. As a secondary objective, we assess the association between antimicrobial use and postoperative infection during the index admission following cystectomy. MATERIALS AND METHODS: The Premier Healthcare Database was queried for all patients undergoing cystectomy with ileal conduit with diagnosis of bladder cancer between 2015 and 2020. Antibiotics used and the duration of use was determined by charge codes and grouped as guidelines-based or not according to 2019 AUA Guidelines. Association with infectious complications was assessed by logistic mixed effects regression models. RESULTS: Among 6,708 patients undergoing cystectomy with ileal conduit, only 28% (1,843/6,708) were given prophylaxis according to AUA guidelines; 1.8% (121/6,708) of patients received an antifungal and 37% (2,482/6,708) received extended duration prophylaxis beyond postoperative day 1. Patients who received guidelines-based prophylaxis were less likely to be diagnosed with a urinary tract infection (21% vs 24%, P = .04), pyelonephritis (5.1% vs 7.7%, P < .001), bacterial infection (24% vs 27%, P = .03), or pneumonia (12% vs 17%, P < .001). There was no statistically significant difference in clostridium difficile infection between guidelines-based and nonguidelines-based prophylaxis (3.2% vs 3.7%, P = .32). In a multivariable logistic regression adjusting for age, race, insurance, and hospital and provider characteristics, nonguideline antibiotic prophylaxis (OR 1.27 [1.12, 1.43], P < .001) was associated with an increased odds of infectious events, whereas a robotic approach (OR 0.82 [0.73, 0.92], P < .001) was associated with lower odds. CONCLUSIONS: Seventy-three percent of patients fail to receive guideline-based antibiotic prophylaxis when undergoing radical cystectomy with conduit, which was largely driven by extended duration antibiotic use. Despite the shorter duration of antibiotics, we found that guideline-based prophylaxis was associated with a 25% decrease in the odds of infectious complications. While residual confounding is possible, these data support current AUA guidelines and suggest a need for outreach to improve guideline adherence.

Human Gut Mycobiome and Fungal Community Interaction: The Unknown Musketeer in the Chemotherapy Response Status in Bladder Cancer.

Background: Until recently, the properties of microbiome and mycobiome in humans and its relevance to disease have largely been unexplored. While the interest of microbiome and malignancy over the past few years have burgeoned with advent of new technologies, no research describing the composition of mycobiome in bladder cancer has been done. Deciphering of the metagenome and its aggregate genetic information can be used to understand the functional properties and relationships between the bacteria, fungi, and cancer. Objective: The aim of this project is to characterize the compositional range of the normal versus bladder cancer mycobiome of the gut. Design setting and participants: An internal transcribed spacer (ITS) survey of 52 fecal samples was performed to evaluate the gut mycobiome differences between noncancer controls and bladder cancer patients. Outcome measurements and statistical analysis: Our study evaluated the differences in mycobiome among patients with bladder cancer, versus matched controls. Our secondary analysis evaluated compositional differences in the gut as a function of response status with neoadjuvant chemotherapy. Data demultiplexing and classification were performed using the QIIME v.1.1.1.1 platform. The Ion Torrent-generated fungal ITS sequence data were processed using QIIME (v.1.9.1), and the reads were demultiplexed, quality filtered, and clustered into operation taxonomic units using default parameters. Alpha and beta diversity were computed and plotted in Phyloseq, principal coordinate analysis was performed on Bray-Curtis dissimilarity indices, and a one-way permutational multivariate analysis of variance was used to test for significant differences between cohorts. Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt) was applied to infer functional categories associated with taxonomic composition. Results and limitations: We found distinctive mycobiome differences between control group (n = 32) and bladder cancer (n = 29) gut flora, and identified an increasing abundance of Tremellales, Hypocreales, and Dothideales. Significant differences in alpha and beta diversity were present between the groups (control vs bladder; p = 0.002), noting distinct compositions within each cohort. A subgroup analysis by sex and neoadjuvant chemotherapy status did not show any further differences in mycobiome composition and diversity. Our results indicate that the gut mycobiome may modulate tumor response to preoperative chemotherapy in bladder cancer patients. We propose that patients with a "favorable" mycobiome composition (eg, high diversity, and low abundance of Agaricomycetes and Saccharomycetes) may have enhanced systemic immune response to chemotherapy through antigen presentation. Conclusions: Our study is the first to characterize the enteric mycobiome in patients with bladder cancer and describe complex ecological network alterations, indicating complex bacteria-fungi interactions, particularly highlighted among patients with complete neoadjuvant chemotherapy response. Patient summary: Our study has demonstrated that the composition of stool mycobiome (fungal inhabitants of the gastrointestinal tract) in patients with bladder cancer is different from that in noncancer individuals. Furthermore, when evaluating how patients respond to chemotherapy given prior to their surgery, our study noted significant differences between patients who responded and those who did not.

Risk factors for postoperative Clostridium difficile infection after radical cystectomy for bladder cancer: a NSQIP database analysis.

INTRODUCTION: Patients undergoing cystectomy for bladder cancer are at an increased risk for Clostridium difficile infection (CDI) due to prolonged antibiotics and underlying comorbidities. We aim to evaluate CDI risk factors in cystectomy patients. MATERIALS AND METHODS: Utilizing National Surgical Quality Improvement Program (NSQIP), patients undergoing cystectomy with diagnosis of bladder cancer between 2015-2017 were included. Baseline demographics including age, sex, comorbidities, and preoperative labs were collected. Univariate and multivariable logistic regression were used to evaluate risk factors for and complications of CDI during the index hospitalization. RESULTS: There were a total of 6,432 patients included in the analysis, with 6,242 (96%) and 190 (4%) in the non-CDI vs. CDI groups, respectively. Patients with a diagnosis of postoperative CDI were more likely to be female [4.09% vs. 2.71%, p = 0.001] and have lower preoperative albumin [3.78 g/dL (0.52) vs. 3.92 g/dL (0.48), p = 0.003]. Patients with a history of female sex (OR 1.46, p = 0.03), neobladder (OR 1.57, p = 0.01), and low preoperative albumin (OR 1.45, p = 0.04) were at the highest risk for development of CDI postoperatively. Patients with a diagnosis of CDI were more likely to experience readmission within 30 days (31.1% vs. 19.2%, p < 0.001). CONCLUSION: Utilizing the NSQIP database, we identified predictors for development of CDI in cystectomy patients. Female sex, continent diversion, and low preoperative albumin all significantly increased the rate of CDI. While our findings are retrospective, they are compelling enough to warrant further prospective investigation.

A Seat at the Table: The Correlation Between Female Authorship and Urology Journal Editorial Board Membership.

BACKGROUND: Gender disparities in editorial board composition exist across a variety of surgical subspecialties. OBJECTIVE: To investigate temporal variation in gender representation on the editorial boards of urology journals and assess the relationship between editorial board composition and female authorship. DESIGN, SETTING, AND PARTICIPANTS: We analyzed female authorship and editorial board composition between 2002 and 2020 among eight high-impact urology journals. Female publication status was assessed using publication records retrieved from PubMed. Editorial board information was manually extracted and titles were grouped for comparison as Editor-in-Chief, mid-level editor, and consulting editors. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Female representation across different editorial levels was analyzed via hierarchical logistic regression with additional terms to test for between-journal differences in overall representation and change over time. The relationship between representation on editorial boards and as publication authors was assessed at the journal level via correlation. RESULTS AND LIMITATIONS: Eight journals and 49 412 articles were analyzed. No female has held the title of Editor-in-Chief for any of these eight journals in 18 yr. Significant growth was seen for mid-level editors, whereas no growth was seen for consulting editors. Neurourology and Urodynamics and Journal of Sexual Medicine had significantly higher than average female editorial board representation (p < 0.05). Across the eight journals, there was a statistically significant correlation between the proportion of overall female authors and female editors (r = 0.93, 95% confidence interval 0.65-0.99). For all journals, the proportion of female contributing authors is greater than the proportion of female editorial board members. CONCLUSIONS: Women in urology represent a small but increasing presence as editorial board members. Clear differences exist between journals, potentially attributable to specialty-specific demographics. Despite increasing representation, no female has ever been appointed Editor-in-Chief for any of the eight journals evaluated. At the journal-specific level, a positive correlation was observed between female editorial staff and female authorship. Given the implication of both academic authorship and editorial board assignment on academic advancement, actionable changes are outlined to guide improvement in gender diversity at the journal level. PATIENT SUMMARY: Females are under-represented on the editorial boards for urology journals, although some roles have seen growth over time. Moreover, female editorial board membership is associated with representation of females among article authors. Gender disparities in both are noteworthy because they affect career paths and contribute to the gender gap in urology.

Impact of Music on Postoperative Pain, Anxiety, and Narcotic Use After Robotic Prostatectomy: A Randomized Controlled Trial.

Background: Music is a safe and cost-effective intervention that can reduce postoperative pain and anxiety. We investigated the effects of music therapy on postoperative recovery in patients undergoing robotic-assisted laparoscopic prostatectomy (RALP). Methods: Subjects were males 18 years and older undergoing RALP at a single tertiary care institution. Patients were randomized to music or control groups. The music group received 30 minutes of music in the recovery area and on postoperative day (POD) 1, while the control group was not provided postoperative music. Inpatient narcotic use (morphine milligram equivalent, or MME) and outpatient narcotic use were measured, and the State-Trait Anxiety Inventory (STAI) survey was completed on POD 1 and POD 7 by an inpatient advanced practitioner (AP). T-test and Chi-square were used to compare the groups. Linear regression was used to adjust for age, blood loss, and inpatient MME. Results: A total of 40 patients were prospectively recruited. There was no statistically significant difference in the hourly MME (2.06 [0.71-3.17] vs. 1.55 [0.83-3.37]) or total MME (49.52 [17-76] vs. 37.25 [20-69]) used in the music vs. non-music arms, respectively. Evaluation of STAI questionnaire revealed no overall differences in anxiety levels among the two groups on POD 1 or POD 7. After adjusting for age, blood loss, and inpatient MME use, patients assigned to the music intervention had a 26% reduction in post-hospitalization use. Conclusion: Our prospective randomized study suggests that music can be an AP-driven adjunct to facilitate postoperative patient comfort and reduce narcotic use upon discharge in prostate cancer patients.

Redefining the Gender Gap in Urology Authorship: An 18-Year Publication Analysis.

BACKGROUND: Academic authorship is a critical productivity metric used for academic promotion. OBJECTIVE: To characterize temporal changes in female representation in academic authorship in ten primary urology journals as the complement of female urologists is increasing. DESIGN, SETTING, AND PARTICIPANTS: Publication records were retrieved from 2002 to 2020 for the ten urology journals with the highest impact factor. The names of all authors were gathered and gender was inferred using first names. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Trends in first and last/senior authorship by gender were evaluated overall, within journals, and by geographic region. RESULTS: A total of 59,375 articles were analyzed, of which 94.1% had gender information for the first author and 94.2% had gender information for the last author. The percentage of overall female authors increased positively from 17.2% (95% highest density interval [HDI] 12.9-21.4%) in 2002 to 27.2% (HDI 21.7-33.6%; p < 0.01) in 2020. Overall female first authorship increased from 15.2% (95% HDI 11.0-19.5%) to 28.5% (95% HDI 21.8-35.6%; p < 0.01). There was also significant growth for female senior authors from 10.4% (95% HDI 7.6-13.5%) to 18.6% (95% HDI 13.6-23.8%; p < 0.01). Assessment of journal-specific changes revealed that Neurourology and Urodynamics (12.6%, 95% HDI 9.9-15.1%) and The Journal of Sexual Medicine (16.2%, 95% HDI 13.6-19.0%) had significantly higher growth in female authorship when compared to Journal of Endourology (7.2%, 95% HDI 5.5-8.7%) and Urologic Oncology (4.5%, 95% HDI 2.0-6.8%; p < 0.05). CONCLUSIONS: Although overall female authorship increased between 2002 and 2020, women remain underrepresented in urology authorship. The percentage of females in senior (last) author positions is less than the percentage of females in first author positions. Journal-specific differences can probably be attributed to gender-based differences in subspecialized fields. PATIENT SUMMARY: In this study, we characterized the underrepresentation of women as authors in urology journals and analyzed the change in female authorship for ten academic urology journals over the course of 18 years. Although the proportion of female authors has increased over that time, the percentage of females in senior authorship roles is less than the percentage of females in first author positions.

Gene network profiling in muscle-invasive bladder cancer: A systematic review and meta-analysis.

BACKGROUND: Determining meta-analysis of transcriptional profiling of muscle-invasive bladder cancer (MIBC) through Gene Expression Omnibus (GEO) datasets has not been investigated. This study aims to define gene expression profiles in MIBC and to identify potential candidate genes and pathways. OBJECTIVES: To review and evaluate gene expression studies in MIBC through publicly available RNA sequencing (RNA-Seq) and microarray data in order to identify potential prognostic and therapeutic targets for MIBC. METHODS: A systematic literature search of the Ovid MEDLINE, PubMed, and Wiley Cochrane Central Register of Controlled Trials databases was performed using the terms "gene," "gene expression," and "bladder cancer" January 1, 1990 through March 2021 focused on populations with MIBC. RESULTS: In the final analysis, GEO datasets were included. Fixed effect model was employed in the meta-analysis. Gene networking connections and gene-set functional analyses of the identified genes as differentially expressed in MIBC were performed using ImaGEO and GeneMANIA software. A heatmap for the upregulated and downregulated genes was generated along with the correlated pathways. CONCLUSION: A total of 9 genes were reported in this analysis. Six genes were reported as upregulated (ProTα, SPINT1, UBE2E1, RAB25, KPNB1, HDAC1) and 3 genes as downregulated (NUP188, IPO13, NUP124). Genes were found to be involved in "ubiquitin mediated proteolysis," "protein processing in endoplasmic reticulum," "transcriptional misregulation in cancer," and "RNA transport" pathways.

Female Sexual Function Following Radical Cystectomy in Bladder Cancer.

INTRODUCTION: A clear and well-documented gender bias exists in the evaluation of sexual outcomes for women undergoing urologic surgery. Due to the anatomic template of anterior exenteration, women are commonly left with side effects that include sexual dysfunction and the perpetuated effects of surgical menopause. OBJECTIVES: To present evaluation and treatment recommendations for female sexual dysfunction treatment and evaluation, in addition to surgical templates during radical cystectomy (RC). METHODS: This article reviews current literature regarding sexual function and RC with urinary diversion in female bladder cancer patients. Furthermore, this review will provide a review of techniques for organ and neurovascular preservation, along with novel vaginal reconstruction templates. Our review will further focus on emerging technology, including minimally invasive surgery and organ and nerve preservation, directed at preservation of female sexual function. RESULTS: Clinically, studies have demonstrated that females who have undergone genitalia-sparing and neurovascular preservation during RC regained sexual activity earlier than patients undergoing traditional RC. If organ and nerve preservation is not feasible due to involvement of trigone or bladder neck, vaginal reconstruction can mitigate the sexual dysfunction that results from a loss of the anterior vagina during a standard RC. CONCLUSION: Female sexual dysfunction is associated with high levels of patient distress and is best comanaged with a multidisciplinary treatment approach, including preoperative counseling, intraoperative nerve, and organ preservation, and postoperative interventions to mitigate sexual side effects.
