Prostate cancer in transgender women: A propensity score-matched analysis of disease severity and survival.

BACKGROUND: Despite the rise in gender-affirming care, our understanding of prostate cancer (PCa) in transgender women (TGW) remains in its infancy. Health disparities and lack of PCa awareness and screening are possible barriers to providing quality care for this population. In addition, the implication of hormonal manipulation for the aggressiveness of PCa in TGW is yet to be determined. Here, this study sought to compare oncological characteristics and survival outcomes between transgender and cisgender (CG) patients with PCa via two national data sets. METHODS: The Veterans Affairs Informatics and Computing Infrastructure database (1999-2020) and the Surveillance, Epidemiology, and End Results-Medicare database (2010-2017) were reviewed. Demographic and clinical details were analyzed. Logistic regression analysis was performed on propensity score-matched groups to identify predictors of high-risk disease and metastasis in patients with PCa. Groups were matched 5:1 (CG:TGW) on the basis of age, race, year of diagnosis, and Charlson Comorbidity Index score. Primary outcomes included metastatic presentation, high-risk localized disease, overall survival (OS), and prostate cancer-specific mortality (PCSM). RESULTS: A total of 1194 patients were included (199 TGW; 995 CG). Associations between transgender identity and metastatic presentation (odds ratio [OR], 0.38; p = .2), high-risk localized disease (OR, 1.19; p = .50), or PCSM (hazard ratio [HR], 0.65; p = .3) were not detected. Transgender identity was associated with improved OS (HR, 0.67; p = .014). CONCLUSIONS: PCa-specific outcomes seem comparable between TGW and CG men, although the study was underpowered to detect modest differences. Further investigation into the incidence and outcomes of PCa in TGW is warranted.

Development of the UroARC Surgical Calculator: A Novel Risk Calculator for Older Adults Undergoing Surgery for Bladder Outlet Obstruction.

PURPOSE: Bladder outlet obstruction (BOO) is common in older adults. Many older adults who pursue surgery have additional vulnerabilities affecting surgical risk, including frailty. A clinical tool that builds on frailty to predict surgical outcomes for the spectrum of BOO procedures would be helpful to aid in surgical decision-making but does not currently exist. MATERIALS AND METHODS: Medicare beneficiaries undergoing BOO surgery from 2014 to 2016 were identified and analyzed using the Medicare MedPAR, Outpatient, and Carrier files. Eight different BOO surgery categories were created. Baseline frailty was calculated for each beneficiary using the Claims-Based Frailty Index (CFI). All 93 variables in the CFI and the 17 variables in the Charlson Comorbidity Index were individually entered into stepwise logistic regression models to determine variables most highly predictive of complications. Similar and duplicative variables were combined into categories. Calibration curves and tests of model fit, including C statistics, Brier scores, and Spiegelhalter P values, were calculated to ensure the prognostic accuracy for postoperative complications. RESULTS: In total, 212,543 beneficiaries were identified. Approximately 42.5% were prefrail (0.15 ≤ CFI < 0.25), 8.7% were mildly frail (0.25 ≤ CFI < 0.35), and 1.2% were moderately-to-severely frail (CFI ≥0.35). Using stepwise logistic regression, 13 distinct prognostic variable categories were identified as the most reliable predictors of postoperative outcomes. Most models demonstrated excellent model discrimination and calibration with high C statistic and Spiegelhalter P values, respectively, and high accuracy with low Brier scores. Calibration curves for each outcome demonstrated excellent model fit. CONCLUSIONS: This novel risk assessment tool may help guide surgical prognostication among this vulnerable population.

Sacral neuromodulation in nursing home residents: Predictors of success and complications in a national cohort of older adults.

AIMS: There is limited evidence to support the efficacy of sacral neuromodulation (SNM) for older adults with overactive bladder (OAB). This study aims to report outcomes following SNM among nursing home (NH) residents, a vulnerable population with high rates of frailty and comorbidity. METHODS: This is a retrospective cohort study of long-stay NH residents who underwent a trial of percutaneous nerve evaluation (PNE) or Stage 1 permanent lead placement (Stage 1) between 2014 and 2016. Residents were identified using the Minimum Data Set linked to Medicare claims. The primary outcome of this study was successful progression from trial to implant. Rates of 1-year device explant/revisions were also investigated. RESULTS: Trial of SNM was observed in 1089 residents (mean age: 77.9 years). PNE was performed in 66.9% of residents and 33.2% underwent Stage 1. Of Stage 1 procedures, 23.8% were performed with simultaneous device implant (single-stage). Overall, 53.1% of PNEs and 72.4% of Stage 1 progressed to device implant, which was associated with Stage 1 procedure versus PNE (adjusted relative risk [aRR]: 1.34; 95% confidence interval [95% CI]: 1.21-1.49) and female versus male sex (aRR: 1.26; 95% CI: 1.09-1.46). One-year explant/revision was observed in 9.3% of residents (6.3% for PNE, 10.5% for Stage 1, 20.3% single-stage). Single stage procedure versus PNE was significantly associated with device explant/revision (aRR: 3.4; 95% CI: 1.9-6.2). CONCLUSIONS: In this large cohort of NH residents, outcomes following SNM were similar to previous reports of younger healthier cohorts. Surgeons managing older patients with OAB should use caution when selecting patients for single stage SNM procedures.

Seeing the unseen: how can we best identify transgender women within the Veterans Affairs healthcare system's electronic medical record?

BACKGROUND: One challenge in transgender research is reliably identifying patients through electronic medical records data, as there is no universal transgender International Classification of Diseases (ICD) code, but rather multiple ICD codes that can be used. AIM: To explore the sensitivity and specificity of 5 commonly used ICD codes to identify transgender patients overall and transgender women specifically (assigned male sex at birth) by using data from the Veterans Affairs (VA), the largest integrated health system in the United States. METHODS: Patients aged ≥18 years were identified via ICD-9 codes 302.5 and 302.6 (Ninth Revision) and ICD-10 codes F64.0, F64.8, and F64.9 (Tenth Revision) using VA health records from 2000 to 2021 and stratified by bilateral orchiectomy status. OUTCOMES: Detailed chart review was performed on 32 randomly selected patients for each code (half with and half without orchiectomy) to confirm transgender status and to perform descriptive analyses. RESULTS: For each ICD code, rates of confirmed transgender status ranged from 88% to 100% for those with and without an orchiectomy, with the majority being transgender women (consistent with most veterans being assigned male sex at birth). Most transgender women (66%-100%) were undergoing estrogen gender-affirming therapy. The majority of provider-driven entries of transgender status took place from 2011 to 2020, with 75% of entries made from 2011 to 2020, consistent with increased recognition and societal acceptance of this population. False negatives were detected at a rate of 15%. Based upon these 5 ICD codes alone, we estimate that the VA has records for 9,449 to 10,738 transgender individuals. CLINICAL IMPLICATIONS: All 5 codes are very sensitive in identifying transgender patients, and the combination of these codes with orchiectomy is extremely sensitive in identifying transgender women, specifically. STRENGTHS AND LIMITATIONS: Major strengths of the study are the use of universal ICD codes and a large patient sample size that spans health records nationally and across multiple decades, potentially making our data more generalizable. The main limitation of this study is that subanalyses were performed on a limited number of patients, which prevented us from capturing all false positives and thus from calculating specificity for each code. Similarly, our true negatives were derived from a small, random subset of the population; as such, our calculation for specificity is an estimate. CONCLUSION: This study highlights a novel method to identify transgender women and paves the way for further research.

Obese men undergoing radical prostatectomy: Is robotic or retropubic better to limit positive surgical margins? Results from SEARCH.

OBJECTIVES: To evaluate the association between obesity and positive surgical margins in patients undergoing retropubic radical prostatectomy versus robotic-assisted laparoscopic prostatectomy. METHODS: We retrospectively reviewed the data of 3141 men undergoing retropubic radical prostatectomy and 1625 undergoing robotic-assisted laparoscopic prostatectomy between 1988 and 2017 at eight Veterans Health Administration hospitals. The positive surgical margin location (peripheral, apical, bladder neck, overall) was determined from pathology reports. We adjusted for age, race, prostate-specific antigen, surgery year, prostate weight, pathological grade group, extracapsular extension, seminal vesicle invasion, hospital surgical volume and surgical method (in analyses not stratified by surgical method). Interactions between body mass index and surgical approach were tested. RESULTS: Among all patients, higher body mass index was associated with increased odds of overall, peripheral and apical positive surgical margins (OR 1.02-1.03, P ≤ 0.02). Although not statistically significant, there was a trend between higher body mass index and increased odds of bladder neck positive surgical margins (OR 1.03, P = 0.09). Interactions between body mass index and surgical method were significant for peripheral positive surgical margins only (P = 0.024). Specifically, there was an association between body mass index and peripheral positive surgical margins among men undergoing retropubic radical prostatectomy (OR 1.04, P < 0.001), but not robotic-assisted laparoscopic prostatectomy (OR 1.00, P = 0.98). Limitations include lacking individual surgeon data and lacking central pathology review. CONCLUSIONS: In this multicenter cohort, higher body mass index was associated with increased odds of positive surgical margins at all locations except the bladder neck. Furthermore, there was a significant association between obesity and peripheral positive surgical margins in men undergoing retropubic radical prostatectomy, but not robotic-assisted laparoscopic prostatectomy. Long-term clinical significance requires further study.

Poorly controlled diabetes increases the risk of metastases and castration-resistant prostate cancer in men undergoing radical prostatectomy: Results from the SEARCH database.

BACKGROUND: Although diabetes is inversely related to prostate cancer (PC) risk, to the authors' knowledge the impact of glycemic control on PC progression is unknown. In the current study, the authors tested the association between hemoglobin A1c (HbA1c) and long-term PC outcomes among diabetic men undergoing radical prostatectomy (RP). METHODS: The authors retrospectively reviewed data regarding men undergoing RP from 2000 to 2017 at 8 Veterans Affairs hospitals. Diabetic patients were identified using International Classification of Diseases, Ninth Revision (ICD-9) codes (250.x) or by an HbA1c value >6.5% at any time before RP. Cox models tested the association between HbA1c and biochemical disease recurrence (BCR), castration-resistant PC (CRPC), metastases, PC-specific mortality, and all-cause mortality. The model for BCR was adjusted for multiple variables. Due to limited events, models for long-term outcomes were adjusted for biopsy grade and prostate-specific antigen only. RESULTS: A total of 1409 men comprised the study population. Of these, 699 patients (50%) had an HbA1c value <6.5%, 631 (45%) had an HbA1c value of 6.5% to 7.9%, and 79 (6%) had an HbA1c value ≥8.0%. Men with an HbA1c value ≥8.0% were younger (P < .001) and more likely to be black (P = .013). The median follow-up after RP was 6.8 years (interquartile range, 3.7-10.6 years). On multivariable analysis, HbA1c was not found to be associated with BCR. However, a higher HbA1c value was associated with metastasis (hazard ratio [HR], 1.21; 95% CI, 1.02-1.44 [P = .031]) and CRPC (HR, 1.27; 95% CI, 1.03-1.56 [P = .023]). Although not statistically significant, there were trends between higher HbA1c and risk of PC-specific mortality (HR, 1.24; 95% CI, 0.99-1.56 [P = .067]) and all-cause mortality (HR, 1.09; 95% CI, 0.99-1.19 [P = .058]). CONCLUSIONS: Among diabetic men undergoing RP, a higher HbA1c value was associated with metastases and CRPC. If validated in larger studies with longer follow-up, future research should test whether better glycemic control improves long-term PC outcomes.

Robotic sacrocolpopexy: adverse events reported to the FDA over the last decade.

INTRODUCTION AND HYPOTHESIS: As surgeons increase the volume of robotic abdominal sacrocolpopexies (rASCs) and become more experienced, a subsequent decrease in the number of adverse events is expected over time. Further, as the leading manufacturer of the operative robot (Intuitive Surgical) improves the technology, adverse events should also decrease. We hypothesized that there has been a decrease in adverse event reporting for rASCs and that serious adverse events are rare. METHODS: We performed a search of the FDA Manufacturer and User Facility Device Experience (MAUDE) database. All entries with the manufacturer "Intuitive Surgical" were exported from 2007 to 2017. All entries with "sacrocolpopexy" were then isolated and analyzed. RESULTS: The number of adverse events reported for rASC peaked in 2013 and 2014, at 107 and 124 respectively. In 2015 and 2016, the number dropped to 11 and 7 respectively. There were 334 reported adverse events from 2007 to 2017. Five (1.50%) were categorized as death, 33 (9.88%) as injury, and 296 (88.62%) as malfunction. Analysis of the malfunction reports found that 15 out of 296 (5.07%) were converted to open surgery, 4 out of 296 (1.3%) were converted to laparoscopic surgery, 4 out of 296 (1.3%) cases were aborted, and 6 out of 296 (2.03%) malfunctions resulted in patient injury. CONCLUSIONS: Although the MAUDE database has its limitations, it does indicate that the number of adverse events reported for rASC peaked in 2013 and 2014 and has decreased annually since then. This may be due to improved proficiency of the surgeon and surgical team, in addition to improvements in the robot. When malfunctions do occur, they infrequently cause serious injury or have an impact on surgical approach.

Prostate-Specific Antigen Values in Transgender Women Receiving Estrogen.

This study examines prostate-specific antigen values among transgender women in the Veterans Health Administration receiving estrogen.

Electrophysiology and structural interventions in adults with congenital heart disease: Comparison of combined versus separate procedures.

BACKGROUND: Electrophysiologic (EP) and structural interventions in adult congenital heart disease (ACHD) are typically completed during separate hospital encounters. With planning/coordination, these cases can be combined. OBJECTIVES: We hypothesized that this integrated approach would yield patient and health system benefits. METHODS: Consecutive ACHD patients undergoing combined interventions were matched to controls with identical but separate procedures. Primary endpoints of total hospital length of stay and cost were compared. RESULTS: Sixty-six combined cases and 120 controls were identified (45% male, mean age 36.2 ± 14.2 years). The most common diagnoses were Fontan (27%), tetralogy of Fallot (23%), and transposition complexes (20%). The most common EP procedure was catheter ablation (n = 30) followed by electrophysiologic study (n = 13); the most common structural intervention was transcatheter valve replacement (n = 16) followed by angioplasty/stenting (n = 14). Compared to controls, cases showed shorter anesthesia duration (323 [IQR 238-405] vs. 355 minutes [270-498], P = 0.06), smaller contrast dose (130 [50-189] vs. 177 mL [94-228], P = 0.045), fewer venipunctures (4 [3-4] vs. 6 [5-7], P < 0.001), and fewer work days missed (2 [2-5] vs. 4 [4-6], P < 0.001). There was shorter hospital stay (30 [19-35] vs. 38 hours [26-50], P = 0.023) and a 37% reduction in hospital charges ($117,894 vs. $187,648; P = 0.039) and 27% reduction in payments ($65,757 vs. $88,859; P = 0.016), persisting after adjustment for group differences. There were no significant differences in number of complications or efficacy. CONCLUSIONS: There appear to be advantages to combining ACHD interventional procedures that include reductions in hospital length of stay and cost, without detectable difference in procedural outcome.

Recurrent Urinary Tract Infections in Females and the Overlap with Overactive Bladder.

PURPOSE OF REVIEW: There are an estimated 33 million men and women with overactive bladder (OAB) in the USA. Despite the prevalence of OAB, it remains a frequently misdiagnosed condition. OAB has shared symptomatology with other common urologic conditions, namely recurrent urinary tract infections (UTIs). Here, we will review key distinguishing features of OAB that aid in establishing an accurate diagnosis and recent advances in OAB management. RECENT FINDINGS: Recent studies have shown that among women presenting with lower urinary tract symptoms, the majority were diagnosed with UTIs and treated without performing a urine culture as routine care. The authors found that when urine cultures were obtained, less than half of women had a positive urine culture, suggesting that empiric treatment of UTIs without cultures commonly led to a misdiagnosis of UTI. The symptoms of OAB have overlap with other common conditions, most notably UTI, BPH, and bladder cancer/carcinoma in situ. Despite the shared symptomatology of OAB and UTI, the timing of symptom onset is usually very different between the two. UTI symptoms are generally acute, whereas those of OAB are generally chronic. OAB and UTI share the common features of urgency, frequency, and nocturia. However, dysuria and hematuria are not features of OAB, while they are frequently seen in UTI. Of note, urgency, frequency, and nocturia are rarely seen in bladder cancer/carcinoma in situ; when these symptoms do occur, it is generally in the setting of microhematuria. One study of patients with carcinoma in situ found that 41% had macroscopic hematuria and 44% had microscopic hematuria at presentation. In patients with lower urinary tract symptoms, it is important to perform a urinalysis (UA) to evaluate for microhematuria to rule out the possibility of malignancy. First-line treatment of OAB (outside the setting of UTI) involves behavioral modification, including bladder training, fluid management, and pelvic floor exercises. Numerous studies have supported behavioral modification strategies as the most efficacious initial step in treatment. Although routinely given for recurrent UTIs and vaginal atrophy in postmenopausal women, several review articles have shown that vaginal estrogen is an effective treatment of lower urinary tract symptoms. The importance of distinguishing OAB from other conditions presenting with similar symptoms is key in preventing misdiagnosis, treatment delays, and antibiotic overuse. Here, we have reviewed key parameters distinguishing OAB from UTI, the most commonly misdiagnosed condition among those presenting with lower urinary tract symptoms (LUTS). Given that UTI is the most commonly misdiagnosed condition among women with OAB, we recommend relying on urine cultures and the constellation of acute-onset dysuria, frequency, and urgency as more important diagnostic factors in distinguishing these conditions.

Prostate Cancer in Transgender Women in the Veterans Affairs Health System, 2000-2022.

This case series investigates the rate of prostate cancer diagnoses among transgender women treated in the Veterans Affairs health system.

Ex vivo gene editing of the dystrophin gene in muscle stem cells mediated by peptide nucleic acid single stranded oligodeoxynucleotides induces stable expression of dystrophin in a mouse model for Duchenne muscular dystrophy.

Duchenne muscular dystrophy (DMD) is a fatal disease caused by mutations in the dystrophin gene, which result in the complete absence of dystrophin protein throughout the body. Gene correction strategies hold promise to treating DMD. Our laboratory has previously demonstrated the ability of peptide nucleic acid single-stranded oligodeoxynucleotides (PNA-ssODNs) to permanently correct single-point mutations at the genomic level. In this study, we show that PNA-ssODNs can target and correct muscle satellite cells (SCs), a population of stem cells capable of self-renewing and differentiating into muscle fibers. When transplanted into skeletal muscles, SCs transfected with correcting PNA-ssODNs were able to engraft and to restore dystrophin expression. The number of dystrophin-positive fibers was shown to significantly increase over time. Expression was confirmed to be the result of the activation of a subpopulation of SCs that had undergone repair as demonstrated by immunofluorescence analyses of engrafted muscles using antibodies specific to full-length dystrophin transcripts and by genomic DNA analysis of dystrophin-positive fibers. Furthermore, the increase in dystrophin expression detected over time resulted in a significant improvement in muscle morphology. The ability of transplanted cells to return into quiescence and to activate upon demand was confirmed in all engrafted muscles following injury. These results demonstrate the feasibility of using gene editing strategies to target and correct SCs and further establish the therapeutic potential of this approach to permanently restore dystrophin expression into muscle of DMD patients.

Prostate-Specific Antigen Screening in Transgender Patients.

CONTEXT: Approximately 0.4-1.3% of the worldwide population is transgender. Although the exact prevalence is unknown, there is an increase in open identification as transgender. Among transgender women (TW), the prostate is retained even after gender-affirmation surgery, thus necessitating ongoing screening for prostate cancer (CaP). However, little is known about CaP screening in this population. OBJECTIVE: To assess our current understanding of CaP incidence and prostate-specific antigen (PSA) screening in TW. EVIDENCE ACQUISITION: We performed a nonsystematic narrative review of all PubMed publications through June 2022 according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement. Given the limited primary research on this subject, case reports were also included. Studies were reviewed to understand PSA screening practices and reports of CaP in this population, as applicable. EVIDENCE SYNTHESIS: There is no consensus regarding PSA screening in TW from any of the major societies, and TW are largely absent from guidelines. Case report data suggest that TW with CaP may have more aggressive disease, and these cancers may have been pre-existing prior to present before gender-affirming hormone therapy (GAHT) or be castrate-resistant. CONCLUSIONS: We are in the infancy of our understanding of PSA screening in TW. Important avenues for future research include understanding the risks/benefits of PSA screening in TW, how best to mitigate potential negative psychological effects of PSA screening in TW, establishing baseline PSA values for those on GAHT (and determining what values should be considered "elevated"), establishing when to initiate PSA screening for those on GAHT, and establishing the accuracy of biomarkers for those undergoing GAHT. PATIENT SUMMARY: We examined patterns of prostate cancer screening for transgender women. Little is known about prostate cancer incidence or screening in this population. Additional research is needed to establish guidelines for screening in this population.

Patient decision-making for surgical treatment of post-prostatectomy stress urinary incontinence: a mixed-methods exploratory pilot study.

Background: Male stress urinary incontinence (SUI) is a known complication following surgical intervention on the prostate, particularly following surgery for prostate cancer. Effective surgical treatments for SUI include artificial urinary sphincter (AUS) and male urethral sling. Prior data suggest that men may forego available treatment despite bothersome symptoms. The objective was to explore how men who underwent surgical correction for post-prostatectomy SUI navigated SUI treatment decisions. Methods: Mixed method study was employed. Semi-structured interviews, participant surveys and objective clinical assessment of SUI were performed among a group of men living with incontinence after prostate cancer surgery who underwent surgery for SUI at the University of California in 2017. Results: Eleven men were interviewed after consultation for SUI and all had complete quantitative clinical data. Surgery for SUI included AUS (n=8) and sling (n=3). There was a decrease in pads per day from 3.2 to 0.9 and no major complications. Most patients found that the impact on activities and their treating urologist were of great importance. Sexual and relationships played a variable role with some participants ranking these as "great deal of influence" and others "little or no influence". Participants who underwent AUS were more likely to cite a higher importance on "being very dry" in choosing that surgery while sling patients had more variable ranking of important factors. Participants found a variety of inputs helpful in hearing information about SUI treatment options. Conclusions: Among a group of 11 men who underwent surgical correction for post-prostatectomy SUI, there were identifiable themes on how men make decisions, evaluate quality of life (QoL) changes and approach treatment options. Men value more than being dry with measures of individual success that can include sexual and relationship health. Furthermore the role of the Urologist remains crucial as patients relied heavily on input and discussion with their Urologist to assist in treatment decisions. These findings can be used to inform future studies of the experience of men with SUI.

Pharmacotherapy for Erectile Dysfunction in 2021 and Beyond.

Erectile dysfunction (ED), defined as the inability to develop or maintain an erection firm enough for satisfactory sexual intercourse, is a common urologic condition that increases in prevalence with age but can affect men of any age. As the discovery of the role of the nitric oxide pathway in inducing and maintaining erections, there have been numerous pharmacologic advancements for the treatment of ED. Here, we will review the mainstays of the pharmacologic treatment of ED: OTC/herbal supplements, phosphodiesterase type V inhibitors (PDE5I), intraurethral suppositories (MUSE), and intracorporal injections (ICI).

Population Trends in Frailty in Older Adults with Benign Urological Conditions in Northern California.

INTRODUCTION: We sought to understand regional variation of frailty across health service areas (HSAs) in Northern and Central California among older adults with benign urological conditions. METHODS: This retrospective study utilizes the University of California, San Francisco Geriatric Urology Database, which includes adults ≥65 years old with benign urological conditions who underwent a Timed Up and Go Test (TUGT) between December 2015 and June 2020. The TUGT is a validated proxy for frailty, whereby a TUGT ≤10 seconds represents robust individuals and a TUGT >10 seconds represents prefrail and frail individuals. Subjects were assigned to the HSA wherein they live, and HSAs were stratified by mean TUGT scores. Analyses were conducted at the HSA level. Characteristics associated with prefrail/frail HSAs were identified using multivariable logistic regression. Least square means were used to determine variation in adjusted mean TUGT scores. RESULTS: A total of 2,596 subjects were stratified into 69 HSAs in Northern and Central California. Twenty-one HSAs were categorized as robust and 48 HSAs were categorized as prefrail/frail. Prefrail/frail HSAs were significantly associated with older age (adjusted odds ratio [aOR] 4.03, CI 3.29-4.94, p <0.001), female sex (aOR 1.10, CI 1.07-1.11, p <0.001), non-White race (aOR 1.12, CI 1.10-1.14, p <0.001), underweight body mass index (BMI; aOR 1.14, CI 1.07-1.22, p <0.001) and obese BMI (aOR 1.06, CI 1.04-1.08, p <0.001). There was a 1.7-fold difference in mean TUGT values across HSAs. CONCLUSIONS: Older age, non-White race, and underweight and obese BMIs are associated with prefrail/frail HSAs. Further investigation into health disparities as they pertain to geography and frailty is needed to expand upon these findings.

The Role of Frailty on Surgical Outcomes Following Pelvic Organ Prolapse Surgery in Medicare Beneficiaries: A National Study.

OBJECTIVE: To evaluate the association of frailty with surgical outcomes following pelvic organ prolapse (POP) surgery in Medicare beneficiaries. METHODS: This is a retrospective cohort study of female Medicare beneficiaries ≥65 years of age undergoing POP surgery between 2014 and 2016. Primary outcomes were hospital length-of-stay (LOS) ≥3 days, 30-day post-operative complications (excluding urinary tract infections (UTI)), and 30-day UTI. Frailty was quantified using the validated Claims-Based Frailty Index (CFI) and categorized into not frail (CFI<0.15), pre-frail (0.15≤CFI<0.25), mildly frail (0.25≤CFI<0.35), and moderately to severely frail (0.35≤CFI≤1). RESULTS: Among the 107,890 women included (mean age, 73.3±6 years), 91.3% were White as and 4.3% were classified as mildly or moderately to severely frail. Rates of hospital LOS≥3 days and 30-day UTI increased over 7-fold and rates of 30-day complications increased over 3-fold as CFI increased from not frail to moderately to severely frail (all P values <.001). Compared to women who were not frail, women who were moderately to severely frail demonstrated an increased relative risk of hospital LOS≥3 days (aRR 3.1 [95% CI 2.5-3.8,P <.001]), 30-day complications (aRR 2.8 [95% CI 2.2-3.6, P <.001]), and 30-day UTI (aRR 2.5 [95% CI 2.2-3.0, P <.001]). CONCLUSION: Among Medicare beneficiaries undergoing POP surgery in the United States, frailty is strongly associated with increased risk of prolonged hospital stay and 30-day complications. Frailty should be considered in the preoperative assessment for POP surgeries to improve patient outcomes.

Seeking the Truth About Primary Elective Cesarean Delivery and Pelvic Floor Disorders: A Systematic Review and Meta-Analysis.

IMPORTANCE: A better understanding of the effect of elective cesarean delivery (CD) on the development of pelvic floor disorders can help obstetricians counsel pregnant women. OBJECTIVE: This study aimed to perform a systematic review and meta-analysis evaluating whether primary elective CD is protective against pelvic floor disorders. STUDY DESIGN: Using the MOOSE criteria, electronic databases were searched for studies that compared the prevalence of pelvic floor disorders among primiparous women. Outcomes of interest were urinary incontinence (UI), fecal incontinence (FI), anal incontinence (AI), and pelvic organ prolapse (POP). Comparisons were made between CD before the onset of labor ("Elective CD"), CD after trial of labor ("Labor CD"), and vaginal delivery (VD). Risk ratios (RRs) were computed using STATA. Between-study heterogeneity was assessed via Cochrane's homogeneity test and review of the I2 statistic. RESULTS: Nineteen studies were included. The overall prevalence of UI for Elective CD was estimated at 7% (95% confidence interval [CI], 3%-13%), Labor CD at 14% (95% CI, 8%-21%), and VD at 26% (95% CI, 20%-32%). Meta-analysis demonstrated a decreased risk of UI after Elective CD compared with Labor CD (RR, 0.75; P = 0.011) or VD (RR, 0.43; P < 0.001). There was a decreased risk of FI or AI after Elective CD compared with VD, but not when compared with Labor CD. Only 2 studies examined POP, precluding meta-analysis. CONCLUSIONS: Among primiparous women, Elective CD may be protective against UI when compared with Labor CD. There was not a protective effect of Elective CD against FI and AI when compared with Labor CD. More data on the effect of elective CD on POP are needed.

Comparative outcomes for older adults undergoing surgery for bladder and bowel dysfunction.

BACKGROUND/OBJECTIVES: To compare surgical outcomes between vulnerable nursing home (NH) residents and matched community-dwelling older adults undergoing surgery for bladder and bowel dysfunction. DESIGN: Retrospective cohort study. PARTICIPANTS: A total of 55,389 NH residents and propensity matched (based on procedure, age, sex, race, comorbidity, and year) community-dwelling older adults undergoing surgery for bladder and bowel dysfunction [female pelvic surgery, transurethral resection of the prostate, suprapubic tube placement, hemorrhoid surgery, rectal prolapse surgery]. Individuals were identified using Medicare claims and the Minimum Data Set (MDS) for NH residents between 2014 and 2016. MEASUREMENTS: Thirty-day complications, 1-year mortality, and weighted changes in healthcare resource utilization (hospital admissions, emergency room visits, office visits) in the year before and after surgery. RESULTS: NH residents demonstrated statistically significant increased risk of 30-day complications [60.1% v. 47.2%; RR 1.3 (95% CI 1.3-1.3)] and 1-year mortality [28.9% vs. 21.3%; RR 1.4 (95% CI 1.3-1.4)], compared to community-dwelling older adults. NH residents also demonstrated decreased healthcare resource utilization, compared to community-dwelling older adults, changing from 3.9 to 1.9 (vs.1.1 to 1.0) hospital admissions, 11 to 10.1 (vs. 9 to 9.7) office visits, and 3.4 to 2.2 (vs. 1.9 to 1.9) emergency room visits from the year before to after surgery. CONCLUSION: Despite matching on several important clinical characteristics, NH residents demonstrated increased rates of 30-day complications and 1-year mortality after surgery for bowel and bladder dysfunction, while demonstrating decreased healthcare resource utilization. These mixed findings suggest that outcomes may be more varied among vulnerable older adults and warrant further investigation.

Robotic Urologic Surgery: Trends in Food and Drug Administration-Reported Adverse Events Over the Last Decade.

Background: The da Vinci Surgical System has led to a rapid growth in the volume of robot-assisted surgeries, with 877,000 surgeries performed in 2017. Despite the increasing prevalence of robotic urologic surgeries, few long-term studies exist that examine trends in reported adverse events (RAEs). We analyzed RAEs over the past decade. Materials and Methods: We extrapolated all entries from the Manufacturer and User Facility Device Experience (MAUDE) database with the manufacturer "Intuitive Surgical" from 2007 to 2017. Reports were analyzed for date and type of RAE (death, bodily injury, malfunction, and other). RAEs from urologic surgeries were analyzed further for specific information pertaining to death, bodily injury, and malfunction. Results: A total of 19,783 RAEs were analyzed. Instrument or robot malfunctions comprised the majority of RAEs (84.9%); bodily injuries comprised 8.2%. Death was the least common RAE (1.3%). RAEs for urologic robotic surgeries peaked in 2013 and 2014 and decreased since. A total of 69 (2.3%) deaths, 364 (12.2%) injuries, and 2544 (85.5%) instrument or robot malfunctions occurred. No reported deaths were attributed to system or mechanical malfunction, but rather to medical complications reported to be unrelated to surgery. The most common injuries were bowel (22.3%) and genitourinary (GU) (19.5%). Instrument malfunctions caused 16.8% of bodily injuries. Conclusions: RAEs for robotic urologic surgeries peaked in 2013 to 2014, and have decreased annually since. When malfunctions occurred, they did not result in death and infrequently resulted in bodily injury. Potential quality improvement targets include prevention of bowel and GU injuries through surgical coaching, and improved technology to prevent malfunction of the surgical system and instruments.
