Abstract
In non-muscle invasive bladder cancer, Bacillus Calmette-Guérin (BCG) responders benefit from strong Th1-type inflammatory and T cell responses mediating tumor rejection. However, the corresponding lack of anti-inflammatory Th2-type immunity impairs tissue repair in the bladder wall and facilitates the development of cystitis, causing urinary pain, urgency, incontinence, and frequency. Mechanistically, the leakage of the glycosaminoglycan (GAG) layer enables an influx of potassium ions, bacteria, and urine solutes towards the underlying bladder tissue, promoting chronic inflammation. Treatments directed towards re-establishing this mucopolysaccharide-based protective barrier are urgently needed. We discuss the pathomechanisms, as well as the therapeutic rationale of how chondroitin and hyaluronic acid instillations can reduce or prevent BCG-induced irritative bladder symptoms. Moreover, we present a case series of five patients with refractory BCG-induced cystitis successfully treated with combined chondroitin and hyaluronic acid instillations.

Abstract
CONTEXT Studies on human renal metabolism are scanty. Nowadays, functional imaging allows the characterization of renal metabolism in a noninvasive manner. We have recently demonstrated that fluorodeoxyglucose F18 (18F FDG) positron emission tomography can be used to analyze renal glucose uptake (GU) rates, and that the renal cortex is an insulin-sensitive tissue. OBJECTIVE To confirm that renal GU is decreased in people with obesity and to test whether circulating metabolites are related to renal GU. DESIGN, SETTING AND PARTICIPANTS Eighteen people with obesity and 18 nonobese controls were studied with [18F]FDG positron emission tomography during insulin clamp. Renal scans were obtained ∼60 minutes after [18F]FDG injection. Renal GU was measured using fractional uptake rate and after correcting for residual intratubular [18F]FDG. Circulating metabolites were measured using high-throughput proton nuclear magnetic resonance metabolomics. RESULTS Cortical GU was higher in healthy nonobese controls compared with people with obesity (4.7 [3.4-5.6] vs 3.1 [2.2-4.3], P = .004, respectively), and it associated positively with the degree of insulin sensitivity (M value) (r = 0.42, P = .01). Moreover, cortical GU was inversely associated with circulating β-OH-butyrate (r = -0.58, P = .009), acetoacetate (r = -0.48, P = .008), citrate (r = -0.44, P = .01), and free fatty acids (r = -0.68, P < .0001), even when accounting for the M value. On the contrary, medullary GU was not associated with any clinical parameters. CONCLUSION These data confirm differences in renal cortical GU between people with obesity and healthy nonobese controls. Moreover, the negative correlations between renal cortex GU and free fatty acids, ketone bodies, and citrate are suggestive of substrate competition in the renal cortex.

Abstract
BACKGROUND In patients affected by high-risk nonmuscle invasive bladder cancer (HR-NMIBC) progression to muscle invasive status is considered as the main indicator of local treatment failure. We aimed to investigate the effect of progression and time to progression on overall survival (OS) and to investigate their validity as surrogate endpoints. METHODS A total of 1,510 patients from 18 different institutions treated for T1 high grade NMIBC, followed by a secondary transurethral resection and BCG intravesical instillation. We relied on random survival forest (RSF) to rank covariates based on OS prediction. Cox's regression models were used to quantify the effect of covariates on mortality. RESULTS During a median follow-up of 49.0 months, 485 (32.1%) patients progressed to MIBC, while 163 (10.8%) patients died. The median time to progression was 82 (95%CI: 78.0-93.0) months. In RSF time-to-progression and age were the most predictive covariates of OS. The survival tree defined 5 groups of risk. In multivariable Cox's regression models accounting for progression status as time-dependent covariate, shorter time to progression (as continuous covariate) was associated with longer OS (HR: 9.0, 95%CI: 3.0-6.7; P < 0.001). Virtually same results after time to progression stratification (time to progression ≥10.5 months as reference). CONCLUSION Time to progression is the main predictor of OS in patients with high risk NMIBC treated with BCG and might be considered a coprimary endpoint. In addition, models including time to progression could be considered for patients' stratification in clinical practice and at the time of clinical trials design.

Abstract
OBJECTIVE To determine the oncological impact of extended pelvic lymph node dissection (ePLND) vs standard PLND (sPLND) during radical cystectomy (RC) in clinically lymph node-positive (cN+) bladder cancer (BCa). PATIENTS AND METHODS In this retrospective, multicentre study we included 969 patients who underwent RC with sPLND (internal/external iliac and obturator lymph nodes) or ePLND (sPLND plus common iliac and presacral nodes) with or without platin-based peri-operative chemotherapy for cTany N1-3 M0 BCa between 1991 and 2022. We assessed the impact of ePLND on recurrence-free survival (RFS) and the distribution of recurrences (locoregional and distant recurrences). The secondary endpoint was overall survival (OS). We performed propensity-score matching using covariates associated with the extent of PLND in univariable logistic regression analysis. The association of the extent of PLND with RFS and OS was investigated using Cox regression models. RESULTS Of 969 cN+ patients, 510 were 1:1 matched on propensity scores. The median (interquartile range [IQR]) time to recurrence was 8 (4-16) months, and median (IQR) follow-up of alive patients was 30 (13-51) months. Disease recurrence was observed in 104 patients in the ePLND and 107 in the sPLND group. Of these, 136 (27%), 47 (9.2%) and 19 patients (3.7%) experienced distant, locoregional, or both distant and locoregional disease recurrence, respectively. When stratified by the extent of PLND, we did not find a difference in recurrence patterns (P > 0.05). ePLND improved neither RFS (hazard ratio [HR] 0.91, 95% confidence interval [CI] 0.70-1.19; P = 0.5) nor OS (HR 0.78, 95% CI 0.60-1.01; P = 0.06) compared to sPLND. Stratification by induction chemotherapy did not change outcomes. CONCLUSION Performing an ePLND at the time of RC in cN+ patients improved neither RFS nor OS compared to sPLND, regardless of induction chemotherapy status. Pretreatment risk stratification is paramount to identify ideal candidates for RC with ePLND as part of a multimodal treatment approach.

Abstract
PURPOSE Aim of the present study was to develop and validate a nomogram to accurately predict the risk of chronic kidney disease (CKD) upstaging at 3 years in patients undergoing robot-assisted partial nephrectomy (RAPN). METHODS A multi-institutional database was queried to identify patients treated with RAPN for localized renal tumor (cT1-cT2, cN0, cM0). Significant CKD upstaging (sCKD-upstaging) was defined as development of newly onset CKD stage 3a, 3b, and 4/5. Model accuracy was calculated according to Harrell C-index. Subsequently, internal validation using bootstrapping and calibration was performed. Then nomogram was depicted to graphically calculate the 3-year sCKD-upstaging risk. Finally, regression tree analysis identified potential cut-offs in nomogram-derived probability. Based on this cut-off, four risk classes were derived with Kaplan-Meier analysis tested this classification. RESULTS Overall, 965 patients were identified. At Kaplan-Meier analysis, 3-year sCKD-upstaging rate was 21.4%. The model included baseline (estimated glomerular filtration rate) eGFR, solitary kidney status, multiple lesions, R.E.N.A.L. nephrometry score, clamping technique, and postoperative acute kidney injury (AKI). The model accurately predicted 3-year sCKD-upstaging (C-index 84%). Based on identified nomogram cut-offs (7 vs 16 vs 26%), a statistically significant increase in sCKD-upstaging rates between low vs intermediate favorable vs intermediate unfavorable vs high-risk patients (1.3 vs 9.2 vs 22 vs 54.2%, respectively, p < 0.001) was observed. CONCLUSION Herein we introduce a novel nomogram that can accurately predict the risk of sCKD-upstaging at 3 years. Based on this nomogram, it is possible to identify four risk categories. If externally validated, this nomogram may represent a useful tool to improve patient counseling and management.

Abstract
BACKGROUND AND OBJECTIVE Venous thromboembolism (VTE) is a significant predictor of worse postoperative morbidity in cancer surgeries. No data have been available for patients with preoperative VTE and upper tract urothelial carcinoma (UTUC) undergoing radical nephroureterectomy (RNU). Our aim was to assess the impact of a preoperative VTE diagnosis on perioperative outcomes in the RNU context. METHODS Patients aged 18 yr or older with a UTUC diagnosis undergoing RNU were identified in the Merative Marketscan Research deidentified databases between 2007 and 2021. Multivariable logistic regression adjusted by relevant perioperative confounders was used to investigate the association between a diagnosis of VTE prior to RNU and 90-d complication rates, postoperative VTE, rehospitalization, and total costs. A sensitivity analysis on VTE severity (pulmonary embolism [PE] and/or deep venous thrombosis [DVT]) was examined. KEY FINDINGS AND LIMITATIONS Within the investigated cohort of 6922 patients, history of any VTE preceding RNU was reported in 568 (8.21%) cases, including DVT (n = 290, 51.06%), PE (n = 169, 29.75%), and superficial VTE (n = 109, 19.19%). The history of VTE before RNU was predictive of higher rates of complications, the most prevalent being respiratory complications (odds ratio [OR]: 1.78, 95% confidence interval [CI]: 1.43-2.22). Preoperative VTE was found to be associated with an increased risk of VTE following RNU (OR: 14.3, 95% CI: 11.48-17.82), higher rehospitalization rates (OR: 1.26, 95% CI 1.01-1.56) other than home discharge status (OR: 1.44, 95% CI: 1.18-1.77), and higher costs (OR 1.42, 95% CI: 1.20-1.68). Limitations include the retrospective nature and the use of an insurance database that relies on accurate coding and does not include information such as pathologic staging. CONCLUSIONS AND CLINICAL IMPLICATIONS The presented findings will contribute to the counseling process for patients. These patients may benefit from enhanced pre/postoperative anticoagulation. More research is needed before the following results can be used in the clinical setting. PATIENT SUMMARY Patients aged 18 yr or older with an upper tract urothelial carcinoma (UTUC) diagnosis undergoing radical nephroureterectomy (RNU) were identified in the Merative Marketscan Research deidentified databases between 2007 and 2021. Multivariable logistic regression adjusted by relevant perioperative confounders was used to investigate the association between a diagnosis of venous thromboembolism (VTE) prior to RNU and 90-d complication rates, postoperative VTE, rehospitalization, and total costs. A sensitivity analysis on VTE severity (pulmonary embolism and/or deep venous thrombosis) was examined. The presented findings will contribute to the counseling of patients with UTUC and preoperative VTE.

Abstract
Background: Robot-assisted partial nephrectomy (RAPN) is increasingly being employed in the management of renal cell carcinoma (RCC) and it is expanding in the field of complex renal tumors. The aim of this systematic review was to consolidate and assess the results of RAPN when dealing with entirely central hilar masses and to examine the various methods used to address the surgical difficulties associated with them. Methods: A thorough literature search in September 2023 across various databases focused on RAPN for renal hilar masses, adhering to PRISMA guidelines. The primary goal was to evaluate RAPN's surgical and functional outcomes, with a secondary aim of examining different surgical techniques. Out of 1250 records, 13 full-text manuscripts were reviewed. Results: Evidence is growing in favor of RAPN for renal hilar masses. Despite a predominance of retrospective studies and a lack of long-term data, RAPN shows positive surgical outcomes and preserves renal function without compromising cancer treatment effectiveness. Innovative suturing and clamping methods are emerging in surgical management. Conclusions: RAPN is a promising technique for managing renal hilar masses in RCC, offering effective surgical outcomes and renal function preservation. The study highlights the need for more long-term data and prospective studies to further validate these findings.

Abstract
OBJECTIVE To explore the associations among mannose, indexes of insulin resistance (IR) and secretion, and long-term cardiovascular outcomes. RESEARCH DESIGN AND METHODS Fasting mannose was assayed in 1,403 participants, one-half of which had a first myocardial infarction (MI) with either normal glucose tolerance (n = 1,045) or newly detected dysglycemia (i.e., impaired glucose tolerance or type 2 diabetes; n = 358). Regression models were used to explore mannose associations with surrogate indexes of IR/insulin secretion. Multivariate Cox models were used to investigate the independent association between high (higher quartile) versus low (lower three quartiles) mannose and major adverse cardiac events (MACE) (n = 163) during the 10-year follow-up. RESULTS Mannose was independently associated with IR indexes (all P ≤ 0.001). High versus low mannose was independently associated with MACE (hazard ratio 1.54, 95% CI 1.07-2.20) in the overall population. CONCLUSIONS Mannose might represent a new biomarker able to track early, potentially detrimental glucometabolic alterations independently of glycemic state.

Abstract
SCOPE Secretion of the gut hormones glucagon-like peptide (GLP-1) and peptide YY (PYY) are induced by nutrients reaching the lower small intestine which regulate insulin and glucagon release, inhibit appetite, and may improve β-cell regeneration. The aim is to test the effect of a slowly digested isomaltulose (ISO) compared to the rapidly digested saccharose (SAC) as a snack given 1 h before a standardized mixed meal test (MMT) on GLP-1, PYY, glucose-dependent insulinotropic peptide (GIP), and metabolic responses in participants with or without type 2 diabetes (T2DM). METHODS AND RESULTS Fifteen healthy volunteers and 15 patients with T2DM consumed either 50 g ISO or SAC 1 h preload of MMT on nonconsecutive days. Clinical parameters and incretin hormones are measured throughout the whole course of MMT. Administration of 50 g ISO as compared to SAC induced a significant increase in GLP-1, GIP, and PYY responses over 2 h after intake of a typical lunch in healthy controls. Patients with T2DM showed reduced overall responses of GLP-1 and delayed insulin release compared to controls while ISO significantly enhanced the GIP and almost tripled the PYY response compared to SAC. CONCLUSION A snack containing ISO markedly enhances the release of the metabolically advantageous gut hormones PYY and GLP-1 and enhances GIP release in response to a subsequent complex meal.

Abstract
BACKGROUND AND OBJECTIVE Growing evidence supports the use of neoadjuvant chemotherapy (NAC) for upper tract urothelial carcinoma (UTUC). However, the implications of residual UTUC at radical nephroureterectomy (RNU) after NAC are not well characterized. Our objective was to compare oncologic outcomes for pathologic risk-matched patients who underwent RNU for UTUC who either received NAC or were chemotherapy-naïve. METHODS We retrospectively identified 1993 patients (including 112 NAC recipients) who underwent RNU for nonmetastatic, high-grade UTUC between 1985 and 2022 in a large, international, multicenter cohort. We divided the cohort into low-risk and high-risk groups defined according to pathologic findings of muscle invasion and lymph node involvement at RNU. Recurrence-free survival (RFS), overall survival (OS), and cancer-specific survival (CSS) estimates were calculated using the Kaplan-Meier method. Multivariable analyses were performed to determine clinical and demographic factors associated with these outcomes. KEY FINDINGS AND LIMITATIONS Among patients with low-risk pathology at RNU, RFS, OS, and CSS were similar between the NAC and chemotherapy-naïve groups. Among patients with high-risk pathology at RNU, the NAC group had poorer RFS (hazard ratio [HR] 3.07, 95% confidence interval [CI] 2.10-4.48), OS (HR 2.06, 95% CI 1.33-3.20), and CSS (subdistribution HR 2.54, 95% CI 1.37-4.69) in comparison to the pathologic risk-matched, chemotherapy-naïve group. Limitations include the lack of centralized pathologic review. CONCLUSIONS AND CLINICAL IMPLICATIONS Patients with residual invasive disease at RNU after NAC represent a uniquely high-risk population with respect to oncologic outcomes. There is a critical need to determine an optimal adjuvant approach for these patients. PATIENT SUMMARY We studied a large, international group of patients with cancer of the upper urinary tract who underwent surgery either with or without receiving chemotherapy beforehand. We identified a high-risk subgroup of patients with residual aggressive cancer after chemotherapy and surgery who should be prioritized for clinical trials and drug development.

At any Level of Adiposity, Relatively Elevated Leptin Concentrations Are Associated With Decreased Insulin Sensitivity. J Clin Endocrinol Metab 2024; 109:461-470.

Abstract
CONTEXT The impact of obesity on glucose homeostasis has high interindividual variability, which may be partially explained by different adipokine concentrations. Leptin regulates energy balance and metabolism, and although its plasma levels are proportional to fat mass, they vary significantly across individuals with the same level of adiposity. OBJECTIVE We tested whether glucose homeostasis differs in subjects with similar degrees of adiposity but different leptin levels. METHODS We analyzed 1290 healthy adults from the Relationship Between Insulin Sensitivity and Cardiovascular Disease study cohort (30-60 years; male/female, 577/713; body mass index [BMI], 25 ± 3 kg/m2) characterized for body composition and metabolic variables with a 75-g oral glucose tolerance test, euglycemic-hyperinsulinemic clamp, β-cell function, and lipidomics. RESULTS Individuals were divided into relatively high and low leptin (RHL and RLL) if they were above or below the sex-specific leptin-fat mass (%) regression. Despite similar glucose tolerance, RHL showed markedly higher fasting and oral glucose tolerance test insulin concentration (+30% and +29%, respectively; P < .0001) and secretion (+17% and +11%, respectively; P < .0001). Regardless of BMI, RHL individuals had lower whole-body (-17-23%, P < .0001) and adipose tissue insulin sensitivity (-24%, P < .0001) compared with RLL. Notably, lean RHL individuals showed similar insulin sensitivity and β-cell function to RLL individuals with overweight/obesity. CONCLUSION Subjects with leptin levels that are inappropriately elevated for their fat mass show whole-body/adipose tissue insulin resistance and hyperinsulinemia, regardless of BMI.

Abstract
INTRODUCTION Aim of the study was to evaluate perioperative, postoperative and mid-term functional outcomes of Florence intracorporeal neobladder (FloRIN) configuration technique performed with stentless procedure. MATERIALS AND METHODS This single institution randomized 1:1 prospective series included consecutive patients treated with Robot-Assisted Radical Cystectomy (RARC) and FloRIN reconfiguration from January 2021 to February 2022. Postoperative complications were graded according to Clavien Dindo classification and divided in early (<30 days from discharge) and delayed (>30 days). RESULTS Overall, 63 patients were included in the analysis. Among these 32 (50.8 %) were treated with RARC + stentless FloRIN while 31 (49.2 %) underwent stent placement procedure. No differences were found in terms of baseline characteristics between the two groups. Stentless procedure was associated with significant shorter console time 328 vs 374 min (p = 0.04) and lower estimated blood loss (EBL) 330 vs 350 ml (p = 0.04) comparing to stent group. As regards perioperative features, no significant differences were recorded in terms of canalization (p = 0.58) and time to drainage removal (p = 0.11) while a shorter length of hospital stay was found in case of stentless procedure (p = 0.04). Early postoperative complications Clavien ≥ 3a occurred in 9.3 % and 12.9 % of patients while delayed major complications were recorded in the 3.1 % and 9.6 % of patients treated with stentless and stent FloRIN, respectively (p = 0.09). As regards the mid-term functional outcomes, no differences were found in terms of kidney function loss in both 3rd and 6th month assessment (p = 0.13 and p = 0.14, respectively). CONCLUSIONS In conclusion, Stentless FloRIN is a feasible and safe IntraCorporeal Neobladder technique, as confirmed by the worthy functional and perioperative outcomes achieved in comparison with the standard FloRIN ureteral management strategy.

Abstract
INTRODUCTION The best approach of the bladder cuff (i.e., transvesical, extravesical, endoscopic) during radical nephroureterectomy (RNU) remains an unsolved question. The aim of this review is to compare the oncological and perioperative outcomes among three different approaches of the distal ureter during RNU. EVIDENCE ACQUISITION A literature search was conducted through June 2022 using PubMed/Medline, Embase, and Web of Science databases. Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines were followed to identify eligible studies. The primary outcome was bladder recurrence-free survival and secondary outcomes included: perioperative outcomes, metastasis-free survival, and cancer-specific survival. EVIDENCE SYNTHESIS A total of 19 non-randomized studies comprising 6581 patients met our inclusion criteria. The risk of bladder recurrence, metastasis and cancer-related death did not differ significantly between each approach (all P>0.05). In subgroup analysis excluding patients with history of bladder cancer, the risk of bladder recurrence remained similar between each approach (all P>0.05). There was no significant difference in terms of operative time, estimated blood loss, length of hospital stay, and postoperative complications between each approach (all P>0.05). The main limitation is the retrospective design of 18/19 included studies. CONCLUSIONS The present systematic review and meta-analysis highlights the lack of high-level evidence on distal ureter management during RNU. On the basis of the available data, the present review supports the equivalence of different techniques of bladder cuff excision during RNU. The extravesical approach seems non-inferior to the transvesical approach in terms of oncological and perioperative outcomes.

Abstract
BACKGROUND Tumors with a high nephrometry score represent a challenging surgical scenario for which robotic partial nephrectomy (RPN) is a primary option in expert hands. OBJECTIVE To compare perioperative and functional outcomes of off-clamp and on-clamp RPN in patients with renal masses with a high RENAL score (≥9). DESIGN, SETTING, AND PARTICIPANTS For this retrospective analysis, an RPN data set including 1604 patients treated at three institutions between 2003 and 2021 was queried for cases with a RENAL score ≥9. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS We used 1:1 propensity score matching (PSM) to select a cohort in which imbalances between the off-clamp and on-clamp groups were minimized. We used χ2 and Student t tests to compare categorical and continuous variables, respectively. The Kaplan-Meier method was used to compare the probability of having an estimated glomerular filtration rate (eGFR) ≥45 ml/min during follow-up. Univariable and multivariable analyses were performed to identify predictors of a trifecta outcome (negative surgical margin status, no Clavien-Dindo grade ≥3 complications, eGFR decline ≤30%) and of retaining eGFR ≥45 ml/min over time. RESULTS AND LIMITATIONS From an overall cohort of 354 patients (142 on-clamp, 212 off-clamp), a homogeneous PSM cohort of 78 patients in each group was selected (p ≥ 0.17). In the PSM cohort, operative time was significantly shorter in the off-clamp group (p < 0.001). There were no differences between the groups in the rates of severe complications (p = 0.32) and positive surgical margins (p = 0.24). The rate of trifecta achievement was significantly higher in the off-clamp group (83.3% vs 67.9%; p = 0.03). Warm ischemia time >20 min was independently negatively associated with trifecta achievement (odds ratio 0.32, 95% confidence interval 0.14-0.74). Moreover, the off-clamp group had a significantly higher probability of retaining eGFR ≥45 ml/min over time (3 yr: 95.9% vs 81.6%; p = 0.03); every 1-min increase in warm ischemia time reduced this probability by 1.3%. CONCLUSIONS We found a favorable trade-off between the benefits and risks of off-clamp RPN, with similar perioperative outcomes and a net benefit in terms of trifecta achievement and long-term renal function outcomes in comparison to on-clamp RPN. PATIENT SUMMARY The complexity of surgery for kidney tumors can be assessed using the RENAL score, which is a measure of the location and size of a kidney tumor. In a multicenter series of patients with tumors with a high RENAL score, we compared outcomes between strategies with (on-clamp) and without (off-clamp) clamping of kidney blood vessels during robot-assisted removal of part of the affected kidney. We found that off-clamp surgery results in better postoperative kidney function.

Abstract
INTRODUCTION Previous radical prostatectomy (RP) for prostate cancer (PCa) might impair feasibility of radical cystectomy (RC) for bladder cancer (BCa). The current study addressed morbidity, operative time (OT), and length of stay (LOS) of RC, within the largest available series of patients with history of previous RP. MATERIALS AND METHODS All patients previously submitted to RP for PCa and subsequently submitted to RC for BCa, at six high-volume European institutions between 2010 and 2019, were identified. Presence of either PCa or BCa metastases, RT as primary treatment for PCa, and palliative RC represented exclusion criteria. The quality criteria for accurate and comprehensive reporting of intra- and post-operative surgical outcomes, recommended by the European Association of Urology guidelines, were fulfilled. Multivariable logistic and Poisson regression analyses were performed. RESULTS Overall, 140 RC patients with history of RP were identified. After RP, 69 (49%) patients received radiotherapy (RT) for PCa, either in adjuvant (n = 50, 36%) or salvage setting (n = 19, 13%). Median age-adjusted Charlson comorbidity index was 6 (IQR 5, 7). Median OT, estimated blood loss and LOS were, respectively, 300 min, 500 ml, and 16 days. Intra-operative transfusions rate was 47% (n = 65). One intra-operative complication occurred (EAUiaiC grade 2, perforation of the rectum managed with immediate repair). Eighty-two (59%) patients experienced a total of 107 post-operative complications during the hospital stay, and seven (5%) patients required hospital readmission. In multivariable regression analyses, RT for PCa was associated with higher risk of post-operative complications (odds ratio 1.82, p = 0.039), longer OT (incidence rate ratio 1.09, p < 0.001), and longer LOS (incidence rate ratio 1.24, p < 0.001). CONCLUSIONS RC in patients with history of RP is feasible, albeit burdened by remarkable morbidity, even in centers of excellence. RT after RP for PCa portends worse surgical outcomes.

Morbidity of elective surgery for localized renal masses among elderly patients: A contemporary multicenter study. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:107014.

Abstract
BACKGROUND The aging population and the incidence of renal cell carcinoma (RCC) are increasing worldwide. Over 25% of newly diagnosed LRM (localized renal masses) occur in patients over the eighth decade of life. The decision-making and treatment approach to LRM in this population represents a clinical dilemma due to inherited decreased functional reserve and competing mortality risks. Current literature reports conflicting evidence regarding age as a risk factor for worst surgical outcomes. As such, we aimed to evaluate the contemporary morbidity of elective surgery for LRM among elderly patients, focusing on intraoperative and postoperative complications. METHODS After Ethical Committee approval, we queried our prospectively maintained databases to identify patients with preoperative eGFR ≥60 ml/min/1.73 m [(David and Bloom, 2022) 22 and a normal contralateral kidney who underwent partial or radical nephrectomy (PN or RN) for a single cT1-T2N0M0 LRM between 1/2015-12/2021 at four high-volume European Academic Institutions. Patients were categorized by age groups: <50 yrs (young) vs. 50-75 (middle-aged) yrs vs.> 75 yrs (elderly). Postoperative complications were recorded according to Clavien-Dindo (CD) classification. The primary objectives were the proportion of patients experiencing intraoperative (IOC), any grade (AGC), and high-grade postoperative complications (HGC), defined as CD grade 3-5. RESULTS Overall, 2469/3076 (80.2%) patients met the inclusion criteria. Of these, 363 (14.7%) were young, 1682 (68.1%) were middle-aged, and 424 (17.2%) were elderly. Compared to middle-aged and young patients, elderly patients had a higher median Charlson Comorbidity Index (6 vs. 4 vs. 0, p < 0.01) and a higher proportion of cT1 renal mass (87.6% vs. 93.0% vs. 93.6%, p < 0.01). No differences among the study groups were found regarding surgical approach (open vs. minimally-invasive) and type of surgery (PN vs. RN). We found that older patients experienced similar IOC (4.5% vs. 4.2% vs. 3.3%, p = 0.7) and AGC (23.1% vs. 20.0% vs. 21.5%, p = 0.4) compared to middle-aged and young patients, respectively. Similarly, there were no significant differences in HGC between the study cohorts (0.7% vs. 1.4% vs. 1.7%, p = 0.8). At multivariable analysis, open approach and PN significantly predicted the occurrence of AGCs, while only the open surgical approach was associated with the occurrence of HGCs. CONCLUSION In kidney cancer tertiary referral centers, the risk of IOC and postoperative HGC after PN or RN for localized renal masses (LRM) is low, despite a non-negligible risk of AGC, especially in elderly patients. Further efforts should focus on identifying multidisciplinary strategies to select patients most likely to benefit from surgery among elderly candidates with LRMs and decrease the morbidity of surgery in this specific setting.

Abstract
BACKGROUND The existence and prognosis of T1LG (T1 low-grade) bladder cancer is controversial. Also, because of data paucity, it remains unclear what is the clinical history of bacillus Calmette-Guérin (BCG) treated T1LG tumors and if it differs from other NMIBC (non-muscle-invasive bladder cancer) representatives. The aim of this study was to analyse recurrence-free survival (RFS) and progression-free survival (PFS) in patients with T1LG bladder cancers treated with BCG immunotherapy. METHODS A multi-institutional and retrospective study of 2510 patients with Ta/T1 NMIBC with or without carcinoma in situ (CIS) treated with BCG (205 T1LG patients) was performed. Kaplan-Meier estimates and log-rank test for RFS and PFS to compare the survival between TaLG, TaHG, T1LG, and T1HG NMIBC were used. Also, T1LG tumors were categorized into EAU2021 risk groups and PFS analysis was performed, and Cox multivariate model for both RFS and PFS were constructed. RESULTS The median follow-up was 52 months. For the T1LG cohort, the estimated RFS and PFS rates at 5-year were 59.3% and 89.2%, respectively. While there were no differences in RFS between NMIBC subpopulations, a slightly better PFS was found in T1LG NMIBC compared to T1HG (5-year PFS; T1LG vs. T1HG: 82% vs. 89%; P<0.001). A heterogeneous classification of patients with T1LG NMIBC was observed when EAU 2021 prognostic model was applied, finding a statistically significant worse PFS in patients classified as high-risk T1LG (5-year PFS; 81.8%) compared to those in intermediate (5-year PFS; 93,4%), and low-risk T1LG tumors (5-year PFS; 98,1%). CONCLUSIONS The RFS of T1LG was comparable to other NMIBC subpopulations. The PFS of T1LG tumors was significantly better than of T1HG NMIBC. The EAU2021 scoring model heterogeneously categorized the risk of progression in T1LG tumors and the high-risk T1LG had the worst PFS.

Abstract
INTRODUCTION The aim of the study was to investigate clinical and surgical factors associated with early catheter replacement in patients treated with Holmium Laser Enucleation of the Prostate (HoLEP). MATERIALS AND METHODS Data of patients treated with HoLEP at our Institution by a single surgeon from March 2017 to January 2021 were collected. Preoperative variables, including non-invasive uroflowmetry and abdominal ultrasonography (US), were recorded. Bladder wall modifications (BWM) at preoperative US were defined as the presence of single or multiple bladder diverticula or bladder wall thickening 5 mm. Clinical symptoms were assessed using validated questionnaires. Only events occurred within the first week after catheter removal were considered. RESULTS Overall, 305 patients were included, of which 46 (15.1%) experienced early catheter replacement. Maintenance of anticoagulants/antiplatelets (AC/AP) therapy at surgery (p=0.001), indwelling urinary catheter (p=0.02) and the presence of BWM (p=0.001) were more frequently reported in patients needing postoperative re-catheterization. Intraoperative complications (p=0.02) and median lasing time (p=0.02) were significantly higher in this group. At univariate analysis, indwelling urinary catheter (p=0.02), BWM (p=0.01), ongoing AC/AP therapy (p=0.01) and intraoperative complications (p=0.01) were significantly associated with early catheter replacement. At multivariate analysis, indwelling urinary catheter (OR: 1.28; p=0.02), BWM (OR: 2.87; p=0.001), and AC/AP therapy (OR: 2.21; p=0.01) were confirmed as independent predictors of catheter replacement. CONCLUSIONS In our experience the presence of indwelling urinary catheter before surgery, BWM and the maintenance of AC/AP therapy were shown to be independent predictors of early catheter replacement after HoLEP.

Abstract
Following a diagnosis of type 1 diabetes (T1D), persisting C-peptide secretion leads to improved glycemic control and outcomes. Residual β-cell function is often assessed with serial mixed-meal tolerance tests, but these tests do not correlate well with clinical outcomes. Herein, we instead use β-cell glucose sensitivity (βGS) to assess changes in β-cell function, incorporating insulin secretion for a given serum glucose into the assessment of β-cell function. We evaluated changes in βGS in individuals enrolled in the placebo arm of 10 T1D trials performed at diabetes onset. We found that βGS showed a more rapid decline in children, as compared with adolescents and adults. Individuals in the top quartile of βGS baseline distribution had a slower rate in loss of glycemic control time over time. Notably, half of this group were children and adolescents. Finally, to identify predictors of glycemic control throughout follow-up, we ran multivariate Cox models and found that incorporating βGS significantly improved the overall model. Taken together, these data suggest that βGS may be of great utility in predicting those more likely to have a more robust clinical remission and may be of use in design of new-onset diabetes clinical trials and in evaluating response to therapies. ARTICLE HIGHLIGHTS We undertook this study to better predict β-cell loss following type 1 diabetes diagnosis. We set out to answer whether β-cell glucose sensitivity (βGS) improves means to evaluate β-cell function postdiagnosis and whether βGS correlates with clinical outcomes. We found that βGS declines faster in children, subjects in the top baseline quartile of βGS exhibit slower β-cell decline (half are children), and incorporating βGS into multivariate Cox models for glycemic improves the model. The implications of our findings are that βGS predicts those likely to have robust clinical remissions and may help with clinical trials design.

Abstract
We evaluate the shared genetic regulation of mRNA molecules, proteins and metabolites derived from whole blood from 3029 human donors. We find abundant allelic heterogeneity, where multiple variants regulate a particular molecular phenotype, and pleiotropy, where a single variant associates with multiple molecular phenotypes over multiple genomic regions. The highest proportion of share genetic regulation is detected between gene expression and proteins (66.6%), with a further median shared genetic associations across 49 different tissues of 78.3% and 62.4% between plasma proteins and gene expression. We represent the genetic and molecular associations in networks including 2828 known GWAS variants, showing that GWAS variants are more often connected to gene expression in trans than other molecular phenotypes in the network. Our work provides a roadmap to understanding molecular networks and deriving the underlying mechanism of action of GWAS variants using different molecular phenotypes in an accessible tissue.

Abstract
BACKGROUND The aim of this study is to investigate the differential stage-dependent outcomes of patients undergoing radical cystectomy (RC) with or without neoadjuvant chemotherapy (NAC). METHODS We performed a retrospective analysis of 1422 patients with cT2-4N0 MIBC treated with RC, with/without cisplatin-based NAC, from our multicenter cooperation program (treated period: 1992-2021). Patients were stratified according to their pathologic stage at RC. Cancer-specific survival (CSS) and overall survival (OS) were calculated using mixed-effects Cox analysis. RESULTS Analysis was conducted on 761 patients treated with NAC followed by RC and 661 treated with RC only (median follow-up 19 months). Of 337 (24%) patients who died, 259 (18%) died of bladder cancer. On univariable analyses, increased pathologic stage was significantly associated with worse CSS (HR=1.59, 95% CI 1.46-1.73; P<0.01) and OS (HR=1.58, 95% CI 1.47-1.71; P<0.001). On multivariable mixed-effects model, patients after RC only had significantly worse CSS with stage pT≥3/N1-3 and OS with stage pT≥2/N0-3 compared to those with stage pT≤1N0. Patients after RC and NAC had significantly worse CSS and OS already at stage ypT≥2/N0-3 compared to those with ypT≤1N0. On subgroup analyses, CSS (HR=4.26; 95% CI 2.03-8.95; P<0.001) but not OS (HR=1.1; 95% CI 0.5-2.4; P=0.81) was worse for pT2N0 patients after NAC versus no-NAC. This difference was not maintained on multivariable analysis. CONCLUSIONS NAC improves pathologic stage at the time of RC. Patients with residual MIBC after NAC have worse survival outcomes compared to those with the same pathologic stage who did not receive NAC, suggesting a need for better adjuvant therapy in these patients.
