RESUMEN

Men with high-risk localized prostate cancer exhibit high rates of post-surgical recurrence. In these patients, androgen deprivation therapy (ADT) is immunomodulatory, however increased infiltration of regulatory T cells (Tregs) may limit the antitumor immune effects of ADT. We designed a neoadjuvant clinical trial to test whether BMS-986218 - a next-generation non-fucosylated anti-CTLA-4 antibody engineered for enhanced antibody-dependent cellular cytotoxicity or phagocytosis (ADCC/P) - depletes intratumoral Tregs and augments the response to ADT. In this single-center, two-arm, open-label study, 24 men with high-risk localized prostate cancer were randomized to receive a single dose of ADT with or without two pre-operative doses of BMS-986218 (anti-CTLA4-NF) prior to radical prostatectomy. Treatment was well tolerated and feasible in the neoadjuvant setting. A secondary clinical outcome was the rate of disease recurrence, which was lower than predicted in both arms. Mechanistically, anti-CTLA4-NF reduced ADT-induced Treg accumulation through engagement of CD16a/ FCGR3A on tumor macrophages, and depth of Treg depletion was quantitatively associated with clinical outcome. Increased intratumoral dendritic cell (DC) frequencies also associated with lack of recurrence, and pre-clinical data suggest ADCC/P-competent anti-CTLA-4 antibodies elicit activation and expansion of tumor DCs. Patients receiving anti-CTLA4-NF also exhibited phenotypic signatures of enhanced antitumor T cell priming. In total, this study provides the first-in-human evidence of Treg depletion by glycoengineered antibodies targeting CTLA-4 in humans and their potential in combination with ADT in prostate cancer patients with high-risk of recurrence.

RESUMEN

Scientists and managers seek to implement more inclusive and effective conservation strategies by incorporating plural valuations of nature and nature's contributions to people (NCP) into research and decision-making. For Argentina's threatened Espinal ecoregion, this need is particularly acute. In Entre Ríos province, practically all of these forests are devoted to production, and the expanding agricultural frontier increases their conversion to crops. We surveyed family ranchers and agricultural/environmental specialists, two key stakeholders for managing Espinal forests used for cattle grazing. Employing a sociocultural valuation, we determined i) stakeholder recognition of the Espinal's NCP and its support for quality of life, ii) similarity between stakeholder valuations (importance: 0 = none; 4 = very) of NCP and dimensions of well-being derived from the Espinal, and iii) relationship between ecological (e.g., forest degradation) and social (e.g., place of residence) factors and perceptions of the forest. Ranchers recognized more NCP and quality-of-life aspects, and the importance to their well-being tended to be greater than specialists. Both groups valued regulating and non-material NCP above material contributions and considered that forests are very important for physical and mental health. Finally, only rancher perceptions varied with tested variables, depending on degradation levels of forests with which they have the most contact and/or carry out their activities, the number of uses and recreational activities they carry out in forests, their knowledge of forests, and their place of residence. This study illustrates common ground upon which to promote synergies between production and conservation in Espinal-cattle agroecosystems.

RESUMEN

INTRODUCTION: Radiation cystitis with hematuria (RCH) is a potentially devastating complication after pelvic radiation. The cumulative incidence of RCH is debated, and certain severe manifestations may require hospital admission. We aimed to evaluate demographics and outcomes of patients hospitalized for RCH. METHODS: We performed a retrospective review of hospitalized patients with a primary or secondary diagnosis of RCH from 2016 to 2019 using the National Inpatient Sample. Our unit of analysis was inpatient encounters. Our primary outcome was inpatient mortality. Secondary outcomes included need for inpatient procedures, transfusion, length of stay (LOS), and cost of admission. We then performed multivariate analysis using either a logistic or linear regression to identify predictors of mortality and LOS. Cost was analyzed using a generalized linear model controlling for LOS. RESULTS: We identified 21,320 weighted cases of hospitalized patients with RCH. The average patient age was 75.4 years, with 84.7% male and 69.3% White. The median LOS was 4 days, and the median cost was $8767. The inpatient mortality rate was 1.3%. The only significant predictor for mortality was older age. The only significant predictor of both higher cost and longer LOS was an Elixhauser Comorbidity Score ≥ 3. CONCLUSIONS: RCH represents a significant burden to patients and the health care system, and we observed an increasing number of hospitalized patients over time. Additional research is needed to identify underlying causes of RCH and effective treatments for this sometimes-severe complication of pelvic radiation.

RESUMEN

INTRODUCTION: Since the integration of the intern year into urology residencies, programs are mandated to introduce fundamental skills to junior residents. Our goal was to assess the impact of one such program: the 2023 New York Section of the AUA (NYS-AUA) EMPIRE (Educational Multi-institutional Program for Instructing REsidents) Boot Camp. METHODS: Junior urology residents from all 10 NYS-AUA institutions attended a free EMPIRE Boot Camp on June 9, 2023. The seminar covered procedural skills including urethral catheterization, cystoscopy, renal and bladder ultrasound, transrectal prostate ultrasound with biopsy, and an introduction to robotics/laparoscopy. Sessions focused on urologic emergencies and postoperative scenarios. Participants completed questionnaires before, immediately after, and 6 months post course, assessing comfort with procedures and overall program quality using a 5-point Likert scale and free text responses. t Tests compared pre and immediate/6-month post scores. RESULTS: Forty junior residents, along with faculty and resident instructors from all 10 NYS-AUA programs, participated. Of the 40 trainees, 35 (87.5%) completed pre- and immediate post-boot camp surveys, while 23 (57.5%) responded to the 6-month follow-up survey. Ratings showed significant improvement in comfort with basic urologic technical skills for 13 out of 14 domains (93%) immediately after the course and at the 6-month mark. Attendees reported notably higher comfort levels in managing obstructive pyelonephritis (P = .003) and postoperative complications (P = .001) following didactic sessions. CONCLUSIONS: A skills-based, free collaborative urology boot camp for junior residents is feasible and can be effective. Trainees reported improved comfort performing certain technical skills and managing urologic emergencies both immediately after the course and at 6 months of follow-up.

RESUMEN

INTRODUCTION: Our goal was to determine if board certification status was associated with improved postoperative outcomes for certain urologic oncology operations. METHODS: We performed a retrospective cohort study of patients aged 65 and over having radical prostatectomy (RP), radical cystectomy (RC), and radical or partial nephrectomy (RPN) by surgeons with New York State licenses from 2015 to 2021 using the Medicare limited dataset. Our primary exposure was surgeon American Board of Urology certification determined by the New York State Physician Profile. All surgeons were in practice for at least 5 years. Our primary outcomes were 90-day mortality, 30-day unplanned readmission, and hospital length of stay (LOS). We used multivariable linear and logistic regression adjusted for surgeon, hospital, and patient characteristics. We performed the analysis in R, and 2-sided P values < .05 were considered statistically significant. RESULTS: We identified 12,601 patients who had a procedure performed. At the time of the procedure, a minority of procedures (1.3%) were performed by nonboard-certified (NBC) urologists. Among the patient cohort, there were 262 and 1419 mortality and readmission events, respectively; median LOS was 2 days (interquartile range 1155). Patients operated on by NBC urologists tended to have lower-volume surgeons who were less likely to be fellowship trained and to have surgery at smaller hospitals. Patients treated by NBC urologists were more likely to have RP, and less likely to have RC and RPN. On multivariate analysis, board certification was protective against readmission for RP (P < .001) and RC (P = .02), longer LOS for RC (P = .001), and mortality for RPN (P = .008). CONCLUSIONS: Urology board certification was associated with fewer readmissions after RP and RC, a shorter LOS after RC, and a lower risk of mortality after RPN. Given low event numbers, these findings require validation with a larger dataset.

RESUMEN

INTRODUCTION: Prolonged indwelling catheter use is a known risk factor for catheter-associated UTIs (CAUTIs). We sought to reduce catheter use by creating and implementing a trial of void (TOV) algorithm to standardize indwelling Foley catheter removal in surgical patients. METHODS: We partnered with the Departments of General Surgery and Nursing to develop an evidence-based TOV algorithm for a step-down unit at a large urban teaching hospital. Our cohort included patients treated with intra-abdominal, thoracic, vascular, urologic, and gynecologic surgeries. The primary outcome was mean cumulative indwelling urethral catheter patient-days. For example, if 2 patients had catheters for 3 and 7 days, respectively, then cumulative catheter days would be 10. We analyzed changes in catheter use 90 days before and after algorithm implementation. RESULTS: The mean number of hospitalized patient-days before and after algorithm introduction did not differ (32.2 vs 32.0, P = .60). After implementation, mean cumulative catheter patient-days decreased (14.8 vs 9.9, P < .01), as did mean daily number of patients with catheters on the unit (3.7 vs 3.1, P = .02). There was 1 CAUTI before and after algorithm implementation, the latter deemed associated with algorithm nonadherence. Catheter use in a surgical floor control group where the algorithm was not implemented did not differ for any outcome over the same time period (P > .05). CONCLUSIONS: A multidisciplinary approach to standardize catheter care with a TOV algorithm is feasible and effective in reducing catheter use. Further research is needed to determine its impact on CAUTI rate.

RESUMEN

INTRODUCTION: The combination of sequential intravesical gemcitabine and docetaxel (Gem/Doce) chemotherapy has been considered a feasible option for BCG (Bacillus Calmette-Guérin) treatment in non-muscle invasive bladder cancer (NMIBC), gaining popularity during BCG shortage period. We seek to determine the efficacy of the treatment by comparing Gem/Doce induction alone vs induction with maintenance, and to evaluate the treatment outcomes of two different dosage protocols. METHODS: A bi-center retrospective analysis of consecutive patients treated with Gem/Doce for NMIBC between 2018 and 2023 was performed. Baseline characteristics, risk group stratification (AUA 2020 guidelines), pathological, and surveillance reports were collected. Kaplan-Meier survival analysis was performed to detect Recurrence-free survival (RFS). RESULTS: Overall, 83 patients (68 males, 15 females) with a median age of 73 (IQR 66-79), and a median follow-up time of 18 months (IQR 9-25), were included. Forty-one had an intermediate-risk disease (49%) and 42 had a high-risk disease (51%). Thirty-seven patients (45%) had a recurrence; 19 (23%) had a high-grade recurrence. RFS of Gem/Doce induction-only vs induction + maintenance was at 6 months 88% vs 100%, at 12 months 71% vs 97%, at 18 months 57% vs 91%, and at 24 months 31% vs 87%, respectively (log-rank, p < 0.0001). Patients who received 2 g Gemcitabine with Docetaxel had better RFS for all-grade recurrences (log-rank, p = 0.017). However, no difference was found for high-grade recurrences. CONCLUSION: Gem/Doce induction with maintenance resulted in significantly better RFS than induction-only. Combining 2 g gemcitabine with docetaxel resulted in better RFS for all-grade but not for high-grade recurrences. Further prospective trials are necessary to validate our results.

RESUMEN

PURPOSE: To describe the incidence and management of patients who develop a prostatic urethral (PU) urothelial carcinoma recurrence after Bacillus Calmette-Guerin (BCG) induction for non-muscle invasive bladder cancer (NMIBC). MATERIALS AND METHODS: We performed a retrospective cohort study of all patients who received BCG induction at our institution from 1996 to 2021 (N = 642) for NMIBC. All patients with pathologically confirmed PU involvement following BCG induction with no known PU involvement pre-BCG were included. We describe the presentation, management, and outcomes for PU recurrence. RESULTS: Among the 642 patients, 21 (3.3%) patients had a PU recurrence after BCG induction. 8 (38%) patients received >2 cycles of BCG induction prior to the recurrence. Median time from induction to PU recurrence was 21 months and 12 (57.1%) patients had concurrent bladder recurrence. At the time of their PU recurrence, 14/21 (67%) of patients were deemed BCG Unresponsive. Nearly all (18/21) were high grade, and 10 were stage Tis, 7 Ta, and 3 T1, and 1 T2. 19/21 (90%) patients received bladder sparing treatment: 6 with TURBT and BCG, 6 with TURBT and intravesical chemotherapy, 5 with TURBT only, and 2 did not receive immediate treatment of their PU recurrence due to advanced stage of disease. 2/21 (9.5%) received a radical cystectomy for initial treatment of the post-BCG PU recurrence, of which all were >pT2. Median follow-up time from BCG induction to the patient's last visit was 64.5 months. Following treatment of PU recurrence, 15/18 patients had another recurrence at a median of 5 months: about 47% of recurrences were bladder only and 14% recurred only in the PU as well. About 1 patient received a RC after the second recurrence and was pT2. CONCLUSION: Patients with PU recurrences following intravesical BCG have a high-risk disease phenotype with a significant risk of recurrence. Conservative management may be appropriate for well-selected patients who do not desire a cystoprostatectomy.

RESUMEN

Context: Land use change drives both biodiversity loss and zoonotic disease transmission in tropical countryside landscapes. Developing solutions for protecting countryside biodiversity, public health, and livelihoods requires understanding the scales at which habitat characteristics such as land cover shape biodiversity, especially for arthropods that transmit pathogens. Evidence increasingly shows that species richness for many taxa correlates with local tree cover. Objectives: We investigated whether mosquito species richness, community composition, and presence of disease vector species responded to land use and tree cover - and if so, whether at spatial scales similar to other taxa. Methods: We paired a field survey of mosquito communities in agricultural, residential, and forested lands in rural southern Costa Rica with remotely sensed tree cover data. We compared mosquito community responses to tree cover surrounding survey sites measured across scales, and analyzed community responses to land use and environmental gradients. Results: Tree cover was positively correlated with mosquito species richness, and negatively correlated with the presence of the common invasive dengue vector Aedes albopictus, particularly at small spatial scales of 80 - 200m. Land use predicted community composition and Ae. albopictus presence. Environmental gradients of tree cover, temperature, and elevation explained 7% of species turnover among survey sites. Conclusions: The results suggest that preservation and expansion of tree cover at local scales can protect biodiversity for a wide range of taxa, including arthropods, and also confer protection against disease vector occurrence. The identified spatial range of tree cover benefits can inform land management for conservation and public health protection.

RESUMEN

In this article, we present results from a literature review of intrinsic, instrumental, and relational values of nature conducted for the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, as part of the Methodological Assessment of the Diverse Values and Valuations of Nature. We identify the most frequently recurring meanings in the heterogeneous use of different value types and their association with worldviews and other key concepts. From frequent uses, we determine a core meaning for each value type, which is sufficiently inclusive to serve as an umbrella over different understandings in the literature and specific enough to help highlight its difference from the other types of values. Finally, we discuss convergences, overlapping areas, and fuzzy boundaries between different value types to facilitate dialogue, reduce misunderstandings, and improve the methods for valuation of nature's contributions to people, including ecosystem services, to inform policy and direct future research.

RESUMEN

OBJECTIVES: To describe formal remediation rates and processes in urology training programs nationally. DESIGN, SETTING, AND PARTICIPANTS: We performed a cross-sectional study by surveying program directors (PDs) through the Society of Academic Urologists. Formal remediation was defined as the process initiated when resident competency deficiencies were significant enough to necessitate documentation and notification of the Graduate Medical Education (GME) office. The primary outcome was the prevalence of urology programs that initiated formal remediation over the past 5 years. Secondary outcomes included reported competency deficiencies and formal remediation processes. RESULTS: Across 148 institutions, 73 (49%) PDs responded to the survey. The majority of PDs (67%, 49/73) stated that at least 1 resident underwent formal remediation over the last 5 years (median 1). "Professionalism" and "Interpersonal and Communication Skills" were the most common competency deficiencies that prompted formal remediation, whereas "Technical Skill" was the least common. While the majority of respondents notified the GME office of residents undergoing remediation, formal remediation plans varied from faculty coaching and mentorship (80%, 39/49) to simulation training (10%, 5/49). Absence of documented faculty feedback on poor performance was the most commonly cited barrier to formal remediation. The majority of PDs reported documentation in a resident's file (81%, 59/73); however, remediation processes differed with only half of PDs reporting that GME offices were routinely involved in creating and overseeing corrective action plans (56%, 41/73). Over the study period, 15% (11/73) of PDs did not promote a resident to the next year of training, and 23% (17/73) of PDs stated "Yes" to graduating a resident who they would not trust to care for a loved one. CONCLUSIONS: Formal remediation among urology residency programs is common, and processes vary across institutions. The most common competency areas prompting remediation were "Professionalism" and "Interpersonal and Communication Skills." Future research should address developing resources to facilitate resident remediation.

RESUMEN

BACKGROUND: Academic and community urology centers participating in a pragmatic clinical trial in non-muscle-invasive bladder cancer completed monthly surveys assessing restrictions in aspects of bladder cancer care due to the COVID-19 Public Health Emergency. Our objective was to describe pandemic-related restrictions on bladder cancer care. METHODS: We invited 32 sites participating in a multicenter pragmatic bladder cancer trial to complete monthly surveys distributed through REDCap beginning in May 2020. These surveys queried sites on whether they were experiencing restrictions in the use of elective surgery, transurethral resection of bladder tumors (TURBT), radical cystectomy, office cystoscopy, and intravesical bacillus Calmette-Guerin (BCG) availability. Responses were collated with descriptive statistics. RESULTS: Of 32 eligible sites, 21 sites had at least a 50% monthly response rate over the study period and were included in the analysis. Elective surgery was paused at 76% of sites in May 2020, 48% of sites in January 2021, and 52% of sites in January 2022. Over those same periods, coinciding with COVID-19 incidence waves, TURBT was restricted at 10%, 14%, and 14% of sites, respectively, radical cystectomy was restricted at 10%, 14%, and 19% of sites, respectively, and cystoscopy was restricted at 33%, 0%, and 10% of sites, respectively. CONCLUSIONS: Bladder cancer care was minimally restricted compared with more pronounced restrictions seen in general elective surgeries during the COVID-19 pandemic.

RESUMEN

When compared to other malignancies, the tumor microenvironment (TME) of primary and castration-resistant prostate cancer (CRPC) is relatively devoid of immune infiltrates. While androgen deprivation therapy (ADT) induces a complex immune infiltrate in localized prostate cancer, the composition of the TME in metastatic castration-sensitive prostate cancer (mCSPC), and the effects of ADT and other treatments in this context are poorly understood. Here, we perform a comprehensive single-cell RNA sequencing (scRNA-seq) profiling of metastatic sites from patients participating in a phase 2 clinical trial (NCT03951831) that evaluated standard-of-care chemo-hormonal therapy combined with anti-PD-1 immunotherapy. We perform a longitudinal, protein activity-based analysis of TME subpopulations, revealing immune subpopulations conserved across multiple metastatic sites. We also observe dynamic changes in these immune subpopulations in response to treatment and a correlation with clinical outcomes. Our study uncovers a therapy-resistant, transcriptionally distinct tumor subpopulation that expands in cell number in treatment-refractory patients.

RESUMEN

PURPOSE OF REVIEW: Management of urotrauma is a crucial part of a urologist's knowledge and training. We therefore sought to understand the state of urotrauma education in the United States. RECENT FINDINGS: Using themes of "Urotrauma" and "Education," we performed a systematic review and meta-analysis by searching for studies in MEDLINE, all Cochrane libraries, EMBASE, BIOSIS, Scopus, and Web of Science through May 2023. The primary outcome was the pooled rate of urology trainee and program director attitudes toward urotrauma education. Secondary outcomes involved a descriptive summary of existing urotrauma curricula and an assessment of factors affecting urotrauma exposure. Of 12,230 unique records, 11 studies met the final eligibility criteria, and we included 2 in the meta-analysis. The majority of trainees and program directors reported having level 1 trauma center rotations (range 88-89%) and considered urotrauma exposure as an important aspect of residency education (83%, 95% CI 76-88%). Despite possible increases in trainee exposure to Society of Genitourinary Reconstructive Surgeons (GURS) faculty over the preceding decade, nearly a third of trainees and program directors currently felt there remained inadequate exposure to urotrauma during training (32%, 95% CI 19-46%). Factors affecting urotrauma education include the limited exposure to GURS-trained faculty and clinical factors such as case infrequency and non-operative trauma management. Urology resident exposure to urotrauma is inadequate in many training programs, underscoring the potential value of developing a standardized curriculum to improve urotrauma education for trainees. Further investigation is needed to characterize this issue and to understand how it impacts trainee practice readiness.

RESUMEN

Twenty-five years since foundational publications on valuing ecosystem services for human well-being1,2, addressing the global biodiversity crisis3 still implies confronting barriers to incorporating nature's diverse values into decision-making. These barriers include powerful interests supported by current norms and legal rules such as property rights, which determine whose values and which values of nature are acted on. A better understanding of how and why nature is (under)valued is more urgent than ever4. Notwithstanding agreements to incorporate nature's values into actions, including the Kunming-Montreal Global Biodiversity Framework (GBF)5 and the UN Sustainable Development Goals6, predominant environmental and development policies still prioritize a subset of values, particularly those linked to markets, and ignore other ways people relate to and benefit from nature7. Arguably, a 'values crisis' underpins the intertwined crises of biodiversity loss and climate change8, pandemic emergence9 and socio-environmental injustices10. On the basis of more than 50,000 scientific publications, policy documents and Indigenous and local knowledge sources, the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) assessed knowledge on nature's diverse values and valuation methods to gain insights into their role in policymaking and fuller integration into decisions7,11. Applying this evidence, combinations of values-centred approaches are proposed to improve valuation and address barriers to uptake, ultimately leveraging transformative changes towards more just (that is, fair treatment of people and nature, including inter- and intragenerational equity) and sustainable futures.
