RESUMEN

Multiple membrane organelles require cholesterol for proper function within cells. The Niemann-Pick type C (NPC) proteins export cholesterol from endosomes to other membrane compartments, including the endoplasmic reticulum (ER), plasma membrane (PM), trans-Golgi network (TGN), and mitochondria, to meet their cholesterol requirements. Defects in NPC cause malfunctions in multiple membrane organelles and lead to an incurable neurological disorder. Acyl-coenzyme A:cholesterol acyltransferase 1 (ACAT1), a resident enzyme in the ER, converts cholesterol to cholesteryl esters for storage. In mutant NPC cells, cholesterol storage still occurs in an NPC-independent manner. Here we report the interesting finding that in a mutant Npc1 mouse (Npc1nmf), Acat1 gene (Soat1) knockout delayed the onset of weight loss, motor impairment, and Purkinje neuron death. It also improved hepatosplenic pathology and prolonged lifespan by 34%. In mutant NPC1 fibroblasts, ACAT1 blockade (A1B) increased cholesterol content associated with TGN-rich membranes and mitochondria, while decreased cholesterol content associated with late endosomes. A1B also restored proper localization of syntaxin 6 and golgin 97 (key proteins in membrane trafficking at TGN) and improved the levels of cathepsin D (a key protease in lysosome and requires Golgi/endosome transport for maturation) and ABCA1 (a key protein controlling cholesterol release at PM). This work supports the hypothesis that diverting cholesterol from storage can benefit multiple diseases that involve cholesterol deficiencies in cell membranes.

RESUMEN

PURPOSE: Active surveillance (AS) with the possibility of delayed intervention (DI) is emerging as a safe alternative to immediate intervention for many patients with small renal masses (SRMs). However, limited comparative data exist to inform the most appropriate management strategy for SRMs. MATERIALS AND METHODS: Decision analytic Markov modeling was performed to estimate the health outcomes and costs of 4 management strategies for 65-year-old patients with an incidental SRM: AS (with possible DI), immediate partial nephrectomy, radical nephrectomy, and thermal ablation. Mortality, direct medical costs, quality-adjusted life-years, and incremental cost-effectiveness ratios were evaluated over 10 years. RESULTS: The 10-year all-cause mortality was 22.6% for AS, 21.9% for immediate partial nephrectomy, 22.4% for immediate radical nephrectomy, and 23.7% for immediate thermal ablation. At a willingness-to-pay threshold of $100,000/quality-adjusted life-year, AS was the most cost-effective management strategy. The results were robust in univariate, multivariate, and probabilistic sensitivity analyses. Clinical decision analysis demonstrated that the tumor's metastatic potential, patient age, individual preferences, and health status were important factors influencing the optimal management strategy. Notably, if the annual probability of metastatic progression from AS was sufficiently low (under 0.35%-0.45% for most ages at baseline), consistent with the typical metastatic potential of SRMs <2 cm, AS would achieve higher health utilities than the other strategies. CONCLUSIONS: Compared to immediate intervention, AS with timely DI offers a safe and cost-effective approach to managing patients with SRMs. For patients harboring tumors of very low metastatic potential, AS may lead to better patient outcomes than immediate intervention.

RESUMEN

PURPOSE: In order to accurately characterize how a history of radiation therapy affects the lifespan of replacement artificial urinary sphincters (AUSs), all possible sources of device failure must be considered. We assessed the competing risks of device failure based on radiation history in men with replacement AUSs. MATERIALS AND METHODS: We identified men who had a replacement AUS in a single institutional, retrospective database. To assess survival from all-cause device failure based on radiation history and other factors, we conducted Kaplan-Meier, Cox proportional-hazards and competing risks analyses. RESULTS: Among 247 men who had a first replacement AUS, men with a history of radiation had shorter time to all-cause device failure (median 1.4 vs 3.5 years for men with radiation vs without radiation history, p=0.02). On multivariable Cox-proportional hazards analysis, previous radiation was associated with increased risk of all-cause device failure (HR: 2.12, 95% CI: 1.30-3.43, p=0.002). On multivariable cause-specific hazards analysis, prior radiation was associated with a higher risk of erosion/infection (HR: 7.57, 95% CI: 2.27-25.2, p <0.001), but was not associated with risk of urethral atrophy (p=0.5) or mechanical failure (p=0.15). CONCLUSIONS: Among men with a replacement AUS, a history of pelvic radiation was associated with shorter time to device failure of any cause. Radiation was also specifically associated with a sevenfold increase in the risk of erosion or infection of replacement AUS, but not with urethral atrophy or mechanical failure. Patients with a replacement AUS should be appropriately counseled on how radiation history may impact outcomes of future revisions.

RESUMEN

PURPOSE: Daily aspirin use following cardiovascular intervention is commonplace and creates concern regarding bleeding risk in patients undergoing surgery. Despite its cardio-protective role, aspirin is often discontinued 5-7 days prior to major surgery due to bleeding concerns. Single institution studies have investigated perioperative outcomes of aspirin use in robotic partial nephrectomy (RPN). We sought to evaluate the outcomes of perioperative aspirin (pASA) use during RPN in a multicenter setting. MATERIALS AND METHODS: We performed a retrospective evaluation of patients undergoing RPN at 5 high volume RPN institutions. We compared perioperative outcomes of patients taking pASA (81 mg) to those not on aspirin. We analyzed the association between pASA use and perioperative transfusion. RESULTS: Of 1,565 patients undergoing RPN, 228 (14.5%) patients continued pASA and were older (62.8 vs 56.8 years, p <0.001) with higher Charlson scores (mean 3 vs 2, p <0.001). pASA was associated with increased perioperative blood transfusions (11% vs 4%, p <0.001) and major complications (10% vs 3%, p <0.001). On multivariable analysis, pASA was associated with increased transfusion risk (OR 1.94, 1.10-3.45, 95% CI). CONCLUSIONS: In experienced hands, perioperative aspirin 81 mg use during RPN is reasonable and safe; however, there is a higher risk of blood transfusions and major complications. Future studies are needed to clarify the role of antiplatelet therapy in RPN patients requiring pASA for primary or secondary prevention of cardiovascular events.

RESUMEN

OBJECTIVE: To assess the quality and accuracy of online videos about the medical management of nephrolithiasis. MATERIALS AND METHODS: To evaluate trends in online interest, we first examined the frequency of worldwide YouTube searches for 'kidney stones' from 2015 to 2020. We then queried YouTube with terms related to symptoms and treatment of kidney stones and analysed English-language videos with >5000 views. Quality was assessed using the validated DISCERN instrument. Evidence-based content analysis of video content and viewer comments was performed. RESULTS: Online searches for videos about kidney stones doubled between 2015 and 2019 (P < 0.001). We analysed 102 videos with a median (range) number of views of 46 539 (5024-3 631 322). The mean (sd) DISCERN score was 3.0 (1.4) out of 5, indicating 'moderate' quality; scores were significantly higher for the 21 videos (21%) authored by academic hospitals (mean 3.7 vs 2.8, P = 0.02). Inaccurate or non-evidence-based claims were identified in 23 videos (23%); none of the videos authored by academic institutions contained inaccurate claims. Videos with inaccurate statements had more than double the viewer engagement (viewer-generated comments, 'thumbs up' and 'thumbs down' ratings) compared to videos without inaccuracies (P < 0.001). Among viewer comments, 43 videos (43%) included comments with inaccurate or non-evidence-based claims, and a large majority (82 videos, 80%) had 'chatbot' recommendations. CONCLUSIONS: Interest in YouTube videos about nephrolithiasis has doubled since 2015. While highly viewed videos vary widely in quality and accuracy, videos produced by academic hospitals have significantly fewer inaccurate claims. Given the high prevalence of stone disease and poor-quality videos, patients should be directed to evidence-based content online.

RESUMEN

OBJECTIVE: To evaluate perioperative complications for open radical prostatectomy (ORP) and robot-assisted RP (RARP) for patients enrolled in the PREvention of VENous ThromboEmbolism Following Radical Prostatectomy (PREVENTER; ClinicalTrials.gov Identifier: NCT03006562) trial, to determine predictors and impact on opioid consumption. PATIENTS AND METHODS: A prospective cohort of 500 patients undergoing ORP and RARP was followed to determine rates of complications and opioid use. Complications were classified 30 days after RP using the Clavien-Dindo system. Patient characteristics and outcomes were compared using appropriate statistical tests. Logistic and linear regressions were performed to identify predictors of complications and evaluate the relationship between complications and postoperative opioid use. RESULTS: A total of 124 (24.8%) men underwent ORP and 376 (75.2%) RARP, with 418 (83.6%) receiving pelvic lymph node dissection (PLND). While 83 patients (16.6%) had complications, only 19 (3.8%) were major (Clavien-Dindo Grade ≥III), with no differences by surgical approach. PLND (odds ratio [OR] 2.96, 95% confidence interval [CI] 1.25-8.71; P = 0.03) and Stage pT3b (OR 2.76, 95% CI 1.23-6.00;P = 0.01) were the only predictors of complications after controlling for potential confounders. Patients who had complications had greater inpatient (P = 0.02) and outpatient (P = 0.005) opioid use, which persisted after controlling for patient-reported pain, attending surgeon variation, surgical approach, and undergoing PLND (inpatient ß:77.2, 95% CI 17.9-136.5,P = 0.03; and outpatient ß:21.9, 95% CI 4.7-39.1,P = 0.01). CONCLUSION: In an analysis of prospectively collected data, overall and major complications rates did not differ by surgical approach. Patients receiving PLND and with Stage pT3b disease had more complications. Complications were independently associated with higher inpatient and outpatient postoperative opioid use.

RESUMEN

PURPOSE: To evaluate the total cost of outpatient flexible cystoscopy associated with reusable device purchase, maintenance, and reprocessing, and to assess potential cost benefits of single-use flexible cystoscopes. METHODS: Cost data regarding the purchasing, maintaining, and reprocessing of reusable flexible cystoscopes were collected using a micro-costing approach at a high-volume outpatient urology clinic. We estimated the costs to facilities with a range of annual procedure volumes (1000-3000) performed with a fleet of cystoscopes ranging from 10 to 25. We also compared the total cost per double-J ureteral stent removal procedure performed using single-use flexible cystoscopes versus reusable devices. RESULTS: The cost associated with reusable flexible cystoscopes ranged from $105 to $224 per procedure depending on the annual procedure volume and cystoscopes available. As a practice became more efficient by increasing the ratio of procedures performed to cystoscopes in the fleet, the proportion of the total cost due to cystoscope reprocessing increased from 22 to 46%. For ureteral stent removal procedures, the total cost per procedure using reusable cystoscopes (range $165-$1469) was higher than that using single-use devices ($244-$420), unless the annual procedure volume was sufficiently high relative to the number of reusable cystoscopes in the fleet (≥ 350 for a practice with ten reusable cystoscopes, ≥ 700 for one with 20 devices). CONCLUSION: The cost of reprocessing reusable cystoscopes represents a large fraction of the total cost per procedure, especially for high-volume facilities. It may be economical to adopt single-use cystoscopes specifically for stent removal procedures, especially for lower-volume facilities.

RESUMEN

PURPOSE: To evaluate the association of post-RP drain placement with post-operative complications and opioid use at a high-volume institution. METHODS: A prospective, comparative cohort study of patients undergoing robot-assisted or open RP was conducted. Patients for two surgeons did not routinely receive pelvic drains ("No Drain" arm), while the remainder routinely placed drains ("Drain" arm). Outcomes were evaluated at 30 days including Clavien-Dindo complications and opioid use. Intention-to-treat primary analysis and additional secondary analyses were performed using appropriate statistical tests and logistic regression. RESULTS: Of 498 total patients, 144 (28.9%) were in the No Drain arm (all robot-assisted) and 354 (71.1%) in the Drain arm. In the No Drain arm, 19 (13.2%) intraoperatively were chosen to receive drains. There was no difference in overall or major (Clavien ≥ 3) complications between groups (p = 0.2 and 0.4, respectively). Drain deferral did not predict complications on multivariable analysis adjusted for age, BMI, comorbidities, clinical risk, surgical approach, operating time, lymphadenectomy, and number of nodes removed [OR 0.61, 95% CI 0.34-1.11, p = 0.10]; nor did it predict symptomatic fluid collection, adjusting for lymphadenectomy and nodes removed [OR 1.14, 95% CI 0.43-3.60, p = 0.8]. Drain deferral did not decrease opioid use (p = 0.5). Per protocol analysis and restriction to robot-assisted cases demonstrated similar results. CONCLUSION: There was no difference in adverse events, complications, symptomatic collections, or opioid use with deferral of routine drain placement after RP. Experienced surgeons may safely defer drain placement in the majority of robot-assisted RP cases.

RESUMEN

PURPOSE OF REVIEW: In light of the announcement that the United States Medical Licensing Examination Step 1 exam will transition to pass/fail reporting, we reviewed recent literature on evaluating residency applicants with a focus on identifying objective measurements of applicant potential. RECENT FINDINGS: References from attending urologists, Step 1 scores, overall academic performance, and research publications are among the most important criteria used to assess applicants. There has been a substantial increase in the average number of applications submitted per applicant, with both applicants and residency directors indicating support for a cap on the number of applications that may be submitted. Additionally, there are increasing efforts to promote diversity with the goal of improving care and representation in urology. Despite progress in standardizing interview protocols, inappropriate questioning remains an issue. Opportunities to improve residency application include promoting diversity, enforcing prohibitions of illegal practices, limiting application numbers, and finding more transparent and equitable screening measures to replace Step 1.

RESUMEN

The advantages of non-uniform sampling (NUS) in offering time savings and resolution enhancement in NMR experiments have been increasingly recognized. The possibility of sensitivity gain by NUS has also been demonstrated. Application of NUS to multidimensional NMR experiments requires the selection of a sampling scheme and a reconstruction scheme to generate uniformly sampled time domain data. In this report, an efficient reconstruction scheme is presented and used to evaluate a range of regularization algorithms that collectively yield a generalized solution to processing NUS data in multidimensional NMR experiments. We compare l1-norm (L1), iterative re-weighted l1-norm (IRL1), and Gaussian smoothed l0-norm (Gaussian-SL0) regularization for processing multidimensional NUS NMR data. Based on the reconstruction of different multidimensional NUS NMR data sets, L1 is demonstrated to be a fast and accurate reconstruction method for both quantitative, high dynamic range applications (e.g. NOESY) and for all J-coupled correlation experiments. Compared to L1, both IRL1 and Gaussian-SL0 are shown to produce slightly higher quality reconstructions with improved linearity in peak intensities, albeit with a computational cost. Finally, a generalized processing system, NESTA-NMR, is described that utilizes a fast and accurate first-order gradient descent algorithm (NESTA) recently developed in the compressed sensing field. NESTA-NMR incorporates L1, IRL1, and Gaussian-SL0 regularization. NESTA-NMR is demonstrated to provide an efficient, streamlined approach to handling all types of multidimensional NMR data using proteins ranging in size from 8 to 32 kDa.

RESUMEN

INTRODUCTION: The completion of residency and start of fellowship training marks a critical transition for urologists in the pursuit of subspeciality training. Most graduating urology residents are under contract until June 30, and most fellowships are scheduled to begin on July 1. There has been no investigation into the practical implications of fellowship delays in urology from a trainee perspective. Our research study aimed to investigate the incidence and predictors of delays in fellowship starts. METHODS: Pediatric urology fellows that began their fellowship training between 2019 and 2023 and endourologic fellows that began their fellowship training between 2017 and 2022 were surveyed using SurveyMonkey®. A total of 250 endourology (EU) fellows and 90 pediatric urology (PU) fellows were contacted. RESULTS: A total of 26.0% and 14.3% of EU and PU fellows, respectively, experienced a delay in their training, despite many leaving their residency positions early (33.8% vs. 44.9%, p=0.2097); 11.7% and 8.2% of EU and PU fellows, respectively, experienced delays they reported to be "very stressful" and 9.1% and 4.1%, respectively, found them "somewhat stressful." Delays of 2-4 weeks were experienced by 5.2% and 6.1%, 4-6-week delays by 7.8% and 4.1%, and delays >6 weeks by 2.6% and 0% of EU and PU fellows, respectively (p=0.0007). CONCLUSIONS: Delays in fellowship training do occur at a notable rate, despite nearly half of urology fellows leaving their residency training positions early, with unclear impacts on patient care and resident colleague well-being. This research highlights the importance of fellowship programs considering delaying fellowship starts to mid-July or August, with support of the prior fellow cohorts.

RESUMEN

INTRODUCTION: Patient-centered communication after surgery can enhance patient satisfaction and reduce unplanned clinical contact. However, patients information needs following kidney stone surgery are not well-understood, limiting quality improvement efforts. We aimed to characterize patient-reported needs in and preferences for postoperative communication following kidney stone surgery. METHODS: Patients undergoing common stone procedures were surveyed about the content, volume, and satisfaction with the communication they received after surgery. Patients indicated which information resources they consulted and found most helpful to address their postoperative care questions. RESULTS: Among 52 patients, the majority (75%) identified varying degrees of deficiencies in the communication they received after surgery. Regarding content, respondents were most interested in understanding how their surgery went (90%), the plan for follow-up care (85%), and the specific location of their stone (85%). Regarding volume, respondents consistently indicated interest in intra-operative findings (stone appearance and location) and postoperative care (stent symptoms and location) but the majority did not recall receiving enough information. To address their questions after surgery, respondents most commonly consulted their urologist (71%), discharge paperwork (42%), electronic health record (27%), and the person with whom their urologist spoke after surgery (25%); among these, the majority (54%) reported that their urologist was the single most helpful source of information. CONCLUSIONS: Following kidney stone surgery, patients report unmet communication needs related to specific intraoperative findings and follow-up care. Patients indicate high levels of satisfaction with urologist-provided resources. These exploratory findings support quality improvement efforts to optimize delivery of effective, patient-centered communication after surgery.

RESUMEN

INTRODUCTION: We aimed to compare holmium laser enucleation of the prostate (HoLEP) outcomes in patients with and without neurologic diseases (ND). METHODS: A prospectively maintained database of patients undergoing HoLEP from January 2021 to April 2022 was reviewed. The following ND s were included: diabetes-related neuropathy/neurogenic bladder, Parkinson's disease, dementia, cerebrovascular accident, multiple sclerosis, traumatic brain injury, transient ischemic attack, brain/spinal tumors, myasthenia gravis, spinal cord injury, and other. Statistical analysis was performed using t-tests, Chi-squared, and binomial tests (p<0.05). RESULTS: A total of 118 ND patients were identified with 135 different neurologic diseases. ND patients were more likely to have indwelling catheters (57% vs. 39%, p=0.012) and urinary tract infections (UTIs) preoperatively (32% vs. 19%, p=0.002). Postoperatively, ND patients were more likely to fail initial trial of void (20% vs. 8.1%, p<0.001) and experience an episode of acute urinary retention (16% vs. 8.5%, p=0.024). Within 90 days postoperative, the overall complication rate was higher in the ND group (26% vs. 13%, p=0.001). Within the ND group, 30/118 (25%) had ≥1 UTI within 90 days preoperative, which decreased to 10/118 (8.7%) 90 days postoperative (p<0.001). At last followup (mean 6.7 months [ND] vs. 5.4 months [non-ND], p=0.03), four patients (4.4%) in the ND group required persistent catheter/clean intermittent catheterization compared to none in the non-ND group (p=0.002). CONCLUSIONS: Patients with ND undergoing HoLEP are more likely to experience postoperative retention and higher complication rates compared to non-ND patients. While UTI rates are higher in this population, HoLEP significantly reduced three-month UTI and catheterization rates.

RESUMEN

Background: Artificial urinary sphincter (AUS) placement remains the gold-standard treatment for post-prostatectomy urinary incontinence (PPUI), despite their need for periodic surgical revision. Objective: To understand the experiences of patients who undergo repeat AUS revisions. Design: Mixed design including quantitative surveys and qualitative interviews for thematic analysis. Methods: Men with ⩾2 revisions were collected from a single-institution, retrospective database of AUS patients. Participants were interviewed about their prostatectomy, incontinence, AUS placement, and revisions. A survey was administered utilizing validated tools (e.g., Decision Regret Scale (DRS), Incontinence Impact Questionnaire-7) for quantitative analysis. Interview transcripts were used for qualitative thematic analysis. Results: Of 26 respondents, 20 completed the interview. Twenty-three men completed the survey. The mean DRS score for prostatectomy was 24 (standard deviation (SD) = 27), indicating low regret. Median Incontinence Impact Questionnaire score was 54 (SD = 27), with 70% of participants describing their PPUI as "severe." Participants experienced a significant decrease in daily pad usage with AUS placement (5.5 pre-AUS vs 1.4 post-AUS, p < 0.0001). Qualitative analysis revealed themes involving prostatectomy urgency, physician-patient relationships, expectation setting, and quality of follow-up. Most participants (96%) were satisfied with their initial AUS placement and endorsed a positive relationship with their urologist. However, 22% of participants were unaware of device limitations, including the need for revision. Some participants (26%) were uncertain of the status of their AUS, while some participants (35%) desired improved follow-up. Conclusions: Initial improvement and positive experiences with urologists motivate patients to undergo AUS repeat revision. Urologists should emphasize the limitations of the AUS before placement and follow up with patients to evaluate their needs for future care.

RESUMEN

Introduction: Intradetrusor onabotulinumtoxinA (OTA) injection is a well-established treatment option for refractory overactive bladder; however, its use at the time of holmium laser enucleation of the prostate (HoLEP) for men with bladder outlet obstruction (BOO) and severe storage symptoms has not been previously reported. Materials and Methods: We retrospectively identified men with BOO and severe storage symptoms who underwent treatment with 200 U of intradetrusor OTA (Botox®) at the time of HoLEP. Patients were propensity score matched to a cohort of HoLEP-only patients based on age, Michigan Incontinence Symptom Index (M-ISI) score, preoperative urinary retention, urge incontinence, and prostate size. Perioperative, postoperative, and patient-reported outcomes were examined between groups. Results: We identified 82 men who underwent HoLEP, including 41 patients in the OTA group and 41 patients in the control group. There was no difference in operative times (59 minutes OTA vs 55 minutes control, p = 0.2), rates of same-day trial of void (TOV) (92% OTA vs 94% control, p = 0.7), or rates of same-day discharge (88% OTA vs 85% control, p = 0.6) between groups. There was no difference in temporary postoperative urinary retention (7% OTA vs 2% control, p = 0.3) between groups. Patients who received OTA injections had a significant reduction in their incontinence scores at 3-month follow-up (M-ISI -8, interquartile range [IQR]: -13 to 0, p < 0.001), whereas control patients did not (M-ISI -5, IQR: -8 to -1, p = 0.2). There was no difference in rates of 90-day complications between groups (OTA 10% vs control 5%, p = 0.7). Conclusions: Intradetrusor OTA at the time of HoLEP is safe and is associated with improved urinary incontinence scores and AUA Symptom Score. Rates of same-day discharge and same-day TOV after HoLEP were not affected by OTA. These findings support the role of OTA as an adjunct to surgical intervention in men with incontinence in the presence of BOO.

RESUMEN

OBJECTIVE: Judicious opioid stewardship would match each patient's prescription to their true medical necessity. However, most prescribing paradigms apply preset quantities and clinical judgment without objective data to predict individual use. We evaluated individual patient and in-hospital parameters as predictors of post-discharge opioid utilization after radical prostatectomy (RP) to provide evidence-based guidance for individualized prescribing. METHODS: A prospective cohort of patients who underwent open or robotic RP were followed in the Opioid Reduction Intervention for Open, Laparoscopic, and Endoscopic Surgery (ORIOLES) initiative. Baseline demographics, in-hospital parameters, and inpatient and post-discharge pain medication utilization were tabulated. Opioid medications were converted to oral morphine equivalents (OMEQ). Predictive factors for post-discharge opioid utilization were analyzed by univariable and multivariable linear regression, adjusting for opioid reduction interventions performed in ORIOLES. RESULTS: Of 443 patients, 102 underwent open and 341 underwent robotic RP. The factors most strongly associated with post-discharge opioid utilization included inpatient opioid utilization in the final 12 hours before discharge (+39.6 post-discharge OMEQ if inpatient OMEQ was >15 vs. 0), maximum patient-reported pain score (range 0-10) in the 12 hours before discharge (+27.6 OMEQ for pain score ≥6 vs. ≤1), preoperative opioid use (+76.2 OMEQ), and body mass index (BMI; +1.4 OMEQ per 1 kg/m2). A final predictive calculator to guide post-discharge opioid prescribing was constructed. CONCLUSIONS: Following RP, inpatient opioid use, patient-reported pain scores, prior opioid use, and BMI are correlated with post-discharge opioid utilization. These data can help guide individualized opioid prescribing to reduce risks of both overprescribing and underprescribing.

RESUMEN

BACKGROUND: For men on active surveillance (AS) for prostate cancer (PCa), disease progression and age-related changes in health may influence decisions about pursuing curative treatment. OBJECTIVE: To evaluate the predicted PCa and non-PCa mortality at the time of reclassification among men on AS, to identify clinical criteria for considering a transition from AS to watchful waiting (WW). DESIGN, SETTING, AND PARTICIPANTS: Patients enrolled in a large AS program who experienced biopsy grade reclassification (Gleason grade increase) were retrospectively examined. All patients who had complete documentation of medical comorbidities at reclassification were included. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: A validated model was used to assess 10- and 15-yr untreated PCa and non-PCa mortalities based on patient comorbidities and PCa clinical characteristics. We compared the ratio of predicted PCa mortality with predicted non-PCa mortality ("predicted mortality ratio") and divided patients into four risk tiers based on this ratio: (1) tier 1 (ratio: >0.33), (2) tier 2 (ratio 0.33-0.20), (3) tier 3 (ratio 0.20-0.10), and (4) tier 4 (ratio <0.10). RESULTS AND LIMITATIONS: Of the 344 men who were reclassified, 98 (28%) were in risk tier 1, 85 (25%) in tier 2, 93 (27%) in tier 3, and 68 (20%) in tier 4 for 10-yr mortality. Fifteen-year risk tiers were distributed similarly. The 23 (6.7%) men who met the "transition triad" (age >75 yr, Charlson Comorbidity Index >3, and grade group ≤2) had a 14-fold higher non-PCa mortality risk and a lower predicted mortality ratio than those who did not (0.07 vs 0.23, p < 0.001). The primary limitations of our study included its retrospective nature and the use of predicted mortalities. CONCLUSIONS: At reclassification, nearly half of patients had a more than five-fold and one in five patients had a more than ten-fold higher risk of non-PCa death than patients having a risk of untreated PCa death. Despite a more significant cancer diagnosis, a transition to WW for older men with multiple comorbidities and grade group <3 PCa should be considered. PATIENT SUMMARY: Men with favorable-risk prostate cancer and life expectancy of >10 yr are often enrolled in active surveillance, which entails delay of curative treatment until there is evidence of more aggressive disease. We examined a group of men on active surveillance who developed more aggressive disease, and found, nevertheless, that the majority of these men continued to have a dramatically higher risk of death from non-prostate cancer causes than from prostate cancer based on a risk prediction tool. For men older than 75 yr, who have multiple medical conditions and who do not have higher-grade cancer, it may be reasonable to reconsider the need for curative treatment given the low risk of death from prostate cancer compared with the risk of death from other causes.

RESUMEN

BACKGROUND: Clinical guidelines have conflicting recommendations on the role of prostate artery embolization (PAE), a novel interventional radiology technique used to treat benign prostatic hyperplasia (BPH). In the absence of consensus among clinicians, patients may seek information online, where consumer-targeted content has proliferated in recent years. Our objective was to assess the content and quality of online information about prostate artery embolization (PAE). METHODS: We evaluated patient interest and exposure to PAE by searching Google Trends for PAE and searching Google for BPH and treatment-related terms. To assess online content about PAE safety and efficacy, we queried Google for patient-oriented websites and YouTube for consumer videos, assessing quality using the validated DISCERN instrument and performing an evidence-based content analysis of how indications, risks, and benefits of PAE were presented. RESULTS: Worldwide searches for PAE peaked in 2019; PAE was mentioned in 15 (26%) of the 57 general BPH-related websites. From our PAE-specific searches, we identified 50 websites and 31 videos. Academic hospitals were the most common sponsor of both PAE-related websites (16, 32%) and videos (15, 48%). Among sources offering PAE to patients, only 15% of websites and 11% of videos explicitly did so as part of a clinical trial. The average DISCERN rating of quality of content was 3.0 out of 5 for websites and 2.0 out of 5 for videos (p < 0.001). Over a quarter of websites and more than half of videos contained potential misinformation, inaccuracies, or non-evidence-based claims about PAE (p = 0.02). CONCLUSIONS: Online consumer information about PAE is of low to moderate quality, with a high frequency of non-evidence-based claims. In the absence of guideline consensus about the role of PAE, clinicians should offer shared decision making and evidence-based counseling about the risks and benefits of PAE.
