This article presents a case series of 25 prostate cancer patients who developed malignant ascites, a rare and aggressive disease progression. The study found that malignant ascites due to prostate cancer is associated with advanced metastatic castration-resistant disease, particularly involving the liver, and poor clinical outcomes despite standard systemic therapy. The median overall survival for the whole cohort was 4 months, with no significant difference between patients who received chemotherapy and those who received supportive care. The article emphasizes the need for better systemic therapy and highlights the importance of providing the best supportive care to improve the quality of life for these patients.

- Abstract
The diagnosis and management of myocardial infarction are increasingly complex, and establishing the presence of intracoronary thrombosis has major implications for both the classification and treatment of myocardial infarction. The aim of this study was to investigate whether positron emission tomographic (PET) and computed tomographic (CT) imaging could noninvasively detect in vivo thrombus formation in human coronary arteries using a novel glycoprotein IIb/IIIa receptor antagonist–based radiotracer,
18 F-GP1. In a single-center observational case-control study, patients with or without acute myocardial infarction underwent coronary18 F-GP1 PET/CT angiography. Coronary artery18 F-GP1 uptake was assessed visually and quantified using maximum target-to-background ratios.18 F-GP1 PET/CT angiography was performed in 49 patients with and 50 patients without acute myocardial infarction (mean age: 61 ± 9 years, 75% men). Coronary18 F-GP1 uptake was apparent in 39 of the 49 culprit lesions (80%) in patients with acute myocardial infarction. False negative results appeared to relate to time delays to scan performance and low thrombus burden in small-caliber distal arteries. On multivariable regression analysis, culprit vessel status was the only independent variable associated with higher18 F-GP1 uptake. Extracoronary cardiac18 F-GP1 findings included a high frequency of infarct-related intramyocardial uptake (35%) as well as left ventricular (8%) or left atrial (2%) thrombus. Coronary18 F-GP1 PET/CT angiography is the first noninvasive selective technique to identify in vivo coronary thrombosis in patients with acute myocardial infarction. This novel approach can further define the role and location of thrombosis within the heart and has the potential to inform the diagnosis, management, and treatment of patients with acute myocardial infarction.

• Deferred cytoreductive nephrectomy represents an appropriate management option. • Deferred cytoreductive nephrectomy demonstrates improved overall survival. • Deferred and upfront cytoreductive nephrectomy carry similar morbidity burden. Deferred cytoreductive nephrectomy (dCN) after upfront systemic therapy has been utilized in the management of select patients with metastatic renal cell carcinoma (mRCC). Herein, we sought to review the current evidence and define oncologic and perioperative outcomes associated with deferred surgical management of newly diagnosed mRCC. Our objective was to critically evaluate the role of dCN in the targeted and immunotherapy eras, comparing oncologic and perioperative outcomes between dCN and upfront CN. Medline, OVID, and Scopus databases were searched for studies evaluating patients undergoing dCN following systemic therapy (ST). PRISMA guidelines were referenced and followed. Outcomes of interest included overall survival (OS), progression free survival (PFS), percent of patients proceeding to dCN, reduction in primary tumor size, complication rates, and perioperative mortality. Random effects meta-analysis was performed comparing overall survival between dCN vs. ST alone and dCN vs. upfront CN. Nineteen studies were included to assess the primary outcomes. The percent of patients proceeding to planned dCN after planned pre-surgical ST ranged from 60.5% to 84%. The most common reason for not undergoing dCN was disease progression on upfront ST. Of patients undergoing dCN, 76% to 96% were able to resume ST postoperatively. OS and PFS ranged from 12.4 to 46 months and 4.5 to 11 months, respectively. Pooled results demonstrated significantly improved OS favoring dCN over upfront CN (hazard ratio, HR = 0.56; 95% CI 0.45–0.69) and ST alone (HR = 0.45; 95% CI 0.38–0.53). Deferred CN represents a potential treatment option in appropriately selected patients with mRCC with a favorable response to upfront systemic therapy. Future randomized trials will be needed to clarify how much this is due to the surgery vs. patient selection. [ABSTRACT FROM AUTHOR]

- Abstract
Bioprosthetic valve thrombosis may have implications for valve function and durability. Using a novel glycoprotein IIb/IIIa receptor radiotracer 18F-GP1, we investigated whether positron emission tomography (PET)-computed tomography (CT) could detect thrombus formation on bioprosthetic aortic valves. Ex vivo experiments were performed on human platelets and explanted bioprosthetic aortic valves. In a prospective cross-sectional study, patients with either bioprosthetic or normal native aortic valves underwent echocardiography, CT angiography, and 18F-GP1 PET-CT. Flow cytometric analysis, histology, immunohistochemistry, and autoradiography demonstrated selective binding of 18F-GP1 to activated platelet glycoprotein IIb/IIIa receptors and thrombus adherent to prosthetic valves. In total, 75 participants were recruited: 53 with bioprosthetic valves (median time from implantation 37 months [IQR: 12-80 months]) and 22 with normal native aortic valves. Three participants had obstructive valve thrombosis, and a further 3 participants had asymptomatic hypoattenuated leaflet thickening on CT angiography. All bioprosthetic valves, but none of the native aortic valves, demonstrated focal 18F-GP1 uptake on the valve leaflets: median maximum target-to-background ratio 2.81 (IQR: 2.29-3.48) vs 1.43 (IQR: 1.28-1.53) (P < 0.001). Higher 18F-GP1 uptake was independently associated with duration of valve implantation and hypoattenuated leaflet thickening. All 3 participants with obstructive valve thrombosis were anticoagulated for 3 months, leading to resolution of their symptoms, improvement in mean valve gradients, and a reduction in 18F-GP1 uptake. Adherence of activated platelets is a common and sustained finding on bioprosthetic aortic valves. 18F-GP1 uptake is higher in the presence of thrombus, regresses with anticoagulation, and has potential use as an adjunctive clinical tool.

- Abstract
• Treatment with PSMA-targeted radiopharmaceuticals is rapidly expanding. • Salivary toxicity has emerged as an important, and potentially dose-limiting, side effect. • Broader use of salivary patient-reported outcomes in trials and practice is needed. • Ample opportunity exists for novel approaches to preserve or restore salivary function. • For now, increasing attention should be given to effective palliation of xerostomia. Clinical trials of prostate-specific membrane antigen (PSMA) targeted radiopharmaceuticals have shown encouraging results. Some agents, like lutetium-177 [177Lu]Lu-PSMA-617 ([
177 Lu]Lu-PSMA-617), are already approved for late line treatment of metastatic castration-resistant prostate cancer (mCRPC). Projections are for continued growth of this treatment modality; [177 Lu]Lu-PSMA-617 is being studied both in earlier stages of disease and in combination with other anti-cancer therapies. Further, the drug development pipeline is deep with variations of PSMA-targeting radionuclides, including higher energy alpha particles conjugated to PSMA-honing vectors. It is safe to assume that an increasing number of patients will be exposed to PSMA-targeted radiopharmaceuticals during the course of their cancer treatment. In this setting, it is important to better understand and mitigate the most commonly encountered toxicities. One particularly vexing side effect is xerostomia. In this review, we discuss the scope of the problem, inventories to better characterize and monitor this troublesome side effect, and approaches to preserve salivary function and effectively palliate symptoms. This article aims to serve as a useful reference for prescribers of PSMA-targeted radiopharmaceuticals, while also commenting on areas of missing data and opportunities for future research.

- Abstract
Objectives: Cardiac MR is widely used to diagnose cardiac amyloid, but cannot differentiate AL and ATTR subtypes: an important distinction given their differing treatments and prognoses. We used PET/MR imaging to quantify myocardial uptake of 18F-fluoride in ATTR and AL amyloid patients, as well as participants with aortic stenosis and age/sex-matched controls. Methods: In this prospective multicenter study, patients were recruited in Edinburgh and New York and underwent 18F-fluoride PET/MR imaging. Standardized volumes of interest were drawn in the septum and areas of late gadolinium enhancement to derive myocardial standardized uptake values (SUV) and tissue-to-background ratio (TBR
MEAN ) after correction for blood pool activity in the right atrium. Results: 53 patients were scanned: 18 with cardiac amyloid (10 ATTR and 8 AL), 13 controls, and 22 with aortic stenosis. No differences in myocardial TBR values were observed between participants scanned in Edinburgh and New York. Mean myocardial TBRMEAN values in ATTR amyloid (1.13 ± 0.16) were higher than controls (0.84 ± 0.11, P =.0006), aortic stenosis (0.73 ± 0.12, P <.0001), and those with AL amyloid (0.96 ± 0.08, P =.01). TBRMEAN values within areas of late gadolinium enhancement provided discrimination between patients with ATTR (1.36 ± 0.23) and all other groups (e.g., AL [1.06 ± 0.07, P =.003]). A TBRMEAN threshold >1.14 in areas of LGE demonstrated 100% sensitivity (CI 72.25 to 100%) and 100% specificity (CI 67.56 to 100%) for ATTR compared to AL amyloid (AUC 1, P =.0004). Conclusion: Quantitative 18F-fluoride PET/MR imaging can distinguish ATTR amyloid from other similar phenotypes and holds promise in improving the diagnosis of this condition.

- Abstract
Background: 18F-Fluoride uptake denotes calcification activity in aortic stenosis and atherosclerosis. While PET/MR has several advantages over PET/CT, attenuation correction of PET/MR data is challenging, limiting cardiovascular application. We compared PET/MR and PET/CT assessments of 18F-fluoride uptake in the aortic valve and coronary arteries.Methods and Results: 18 patients with aortic stenosis or recent myocardial infarction underwent 18F-fluoride PET/CT followed immediately by PET/MR. Valve and coronary 18F-fluoride uptake were evaluated independently. Both standard (Dixon) and novel radial GRE) MR attenuation correction (AC) maps were validated against PET/CT with results expressed as tissue-to-background ratios (TBRs). Visually, aortic valve 18F-fluoride uptake was similar on PET/CT and PET/MR. TBRMAX values were comparable with radial GRE AC (PET/CT 1.55±0.33 vs. PET/MR 1.58 ± 0.34, P = 0.66; 95% limits of agreement - 27% to + 25%) but performed less well with Dixon AC (1.38 ± 0.44, P = 0.06; bias (-)14%; 95% limits of agreement - 25% to + 53%). In native coronaries, 18F-fluoride uptake was similar on PET/MR to PET/CT regardless of AC approach. PET/MR identified 28/29 plaques identified on PET/CT; however, stents caused artifact on PET/MR making assessment of 18F-fluoride uptake challenging.Conclusion: Cardiovascular PET/MR demonstrates good visual and quantitative agreement with PET/CT. However, PET/MR is hampered by stent-related artifacts currently limiting clinical application. [ABSTRACT FROM AUTHOR]- Published

Successful navigation of the social environment is dependent on a number of social cognitive processes, including mentalizing and resistance to peer influence. These processes continue to develop during adolescence, a time of significant social change, and are underpinned by regions of the social brain that continue to mature structurally and functionally into adulthood. In this review, we describe how mentalizing, peer influence, and emotion regulation capacities develop to aid the navigation of the social environment during adolescence. Heightened susceptibility to peer influence and hypersensitivity to social rejection in adolescence increase the likelihood of both risky and prosocial behavior in the presence of peers. Developmental differences in mentalizing and emotion regulation, and the corticosubcortical circuits that underpin these processes, might put adolescents at risk for developing mental health problems. We suggest how interventions aimed at improving prosocial behavior and emotion regulation abilities hold promise in reducing the risk of poor mental health as adolescents navigate the changes in their social environment.

Objective: To guide treatment decisions for symptomatic lymphoceles after radical prostatectomy. We examined our experience to create a treatment algorithm.Materials and Methods: We evaluated all patients that underwent radical prostatectomy at our institution from 2003 to 2012. Presenting signs, management and treatment outcomes were evaluated.Results: Of the 8081 patients who underwent radical prostatectomy from 2003 to 2012, we identified 123 (1.5%) patients who developed a symptomatic lymphocele, 70 sterile and 53 infected. Percutaneous aspiration was performed in 26 of 123 (21%) patients, of those, 100% recurred. A drain was placed in 86 of 123 (70%) patients for a median of 13 vs 33 days for the infected and sterile lymphocele groups, respectively (P <.001). The median duration of drainage for sterile lymphoceles was 15 vs 58 days for lymphoceles <10 cm vs ≥10 cm (P <.001). Percutaneous drainage was successful in 93% and 86% of patients with infected and sterile lymphoceles, respectively. Laparoscopic unroofing was performed in 18 sterile lymphocele patients (15%) with a success rate of 94%.Conclusion: Aspiration of symptomatic lymphoceles should be reserved for diagnostic purposes due to a high risk of recurrence. Infected lymphoceles are optimally treated with drain placement and antibiotics, and have excellent resolution rates. While sterile lymphoceles <10 cm can be successfully managed with drain placement, if drainage and sclerotherapy fail, laparoscopic unroofing should be considered. For patients with sterile lymphoceles ≥10 cm there should be a shared decision-making process to weigh the risk of a protracted course if a drain is utilized vs upfront laparoscopic unroofing.

- Abstract
The goal of this study was to determine whether ticagrelor reduces high-sensitivity troponin I concentrations in patients with established coronary artery disease and high-risk coronary plaque. High-risk coronary atherosclerotic plaque is associated with higher plasma troponin concentrations suggesting ongoing myocardial injury that may be a target for dual antiplatelet therapy. In a randomized, double-blind, placebo-controlled trial, patients with multivessel coronary artery disease underwent coronary
18 F-fluoride positron emission tomography/coronary computed tomography scanning and measurement of high-sensitivity cardiac troponin I. Patients were randomized (1:1) to receive ticagrelor 90 mg twice daily or matched placebo. The primary endpoint was troponin I concentration at 30 days in patients with increased coronary18 F-fluoride uptake. In total, 202 patients were randomized to treatment, and 191 met the pre-specified criteria for inclusion in the primary analysis. In patients with increased coronary18 F-fluoride uptake (120 of 191), there was no evidence that ticagrelor had an effect on plasma troponin concentrations at 30 days (ratio of geometric means for ticagrelor vs. placebo: 1.11; 95% confidence interval: 0.90 to 1.36; p = 0.32). Over 1 year, ticagrelor had no effect on troponin concentrations in patients with increased coronary18 F-fluoride uptake (ratio of geometric means: 0.86; 95% confidence interval: 0.63 to 1.17; p = 0.33). Dual antiplatelet therapy with ticagrelor did not reduce plasma troponin concentrations in patients with high-risk coronary plaque, suggesting that subclinical plaque thrombosis does not contribute to ongoing myocardial injury in this setting.

Long-term data comparing partial nephrectomy (PN) and thermal ablation are lacking. To update our experience with PN, percutaneous radiofrequency ablation (RFA), and percutaneous cryoablation for cT1 renal masses. A total of 1798 patients with primary cT1N0M0 renal masses treated between 2000 and 2011 at Mayo Clinic were identified. Percutaneous ablation versus PN. Cancer-specific survival (CSS) was estimated using the Kaplan-Meier method. Local recurrence, metastases, and death from renal cell carcinoma (RCC) were compared with propensity-score–adjusted Cox models. Among 1422 cT1a patients, 1055, 180, and 187 underwent PN, RFA, and cryoablation with median clinical follow-up of 9.4, 7.5, and 6.3 yr, respectively. Comparisons of RFA with PN resulted in hazard ratios (HRs) of 1.49 (95% confidence interval [CI] 0.55–4.04, p = 0.4), 1.46 (95% CI 0.41–5.19, p = 0.6), and 1.99 (95% CI 0.29–13.56, p = 0.5) for local recurrence, metastases, and death from RCC. Comparisons of cryoablation to PN resulted in HRs of 1.88 (95% CI 0.76–4.66, p = 0.18), 0.23 (95% CI 0.03–1.72, p = 0.15), and 0.29 (95% CI 0.01–6.11, p = 0.4) for these same outcomes. Five-year CSS was 99%, 96%, and 100% for PN, RFA, and cryoablation, respectively. Among 376 cT1b patients, 324 and 52 underwent PN and cryoablation with median clinical follow-up of 8.7 and 6.0 yr, respectively. Comparisons of cryoablation with PN resulted in HRs of 1.22 (95% CI 0.33–4.48, p = 0.8), 0.95 (95% CI 0.21–4.38, p > 0.9), and 1.94 (95% CI 0.42–8.96, p = 0.4) for local recurrence, metastases, and death from RCC, respectively. Five-year CSS was 98% and 91% for PN and cryoablation, respectively. Limitations include retrospective review and selection bias. With mature follow-up at a single institution, percutaneous ablation appears to have acceptable results for cT1 renal tumors and is appropriate for patients with a contraindication for surgery. For cT1a patients, clinically relevant differences between PN and ablation are unlikely, and treatment choice should involve shared decision making. For cT1b patients, death from RCC was more common with cryoablation, and large differences in this outcome cannot be ruled out. Further research is needed to confirm the oncologic effectiveness of cryoablation in the cT1b setting. With appropriate patient triage, partial nephrectomy and percutaneous ablation can be used to treat cT1 renal masses, although additional follow-up and further study are still needed. Percutaneous ablation appears to have acceptable results for cT1 renal tumors. With appropriate patient triage, partial nephrectomy and percutaneous ablation can be used to treat cT1 renal masses, although additional follow-up and further study are still needed.

The coronavirus disease 2019 (COVID-19) pandemic has resulted in the widespread implementation of social distancing measures. Adhering to social distancing may be particularly challenging for adolescents, for whom interaction with peers is especially important. We argue that young people's capacity to encourage each other to observe social distancing rules should be harnessed. [ABSTRACT FROM AUTHOR]

In the past decade, there have been extensive efforts in the Western world to raise public awareness about mental health problems, with the goal of reducing or preventing these symptoms across the population. Despite these efforts, reported rates of mental health problems have increased in these countries over the same period. In this paper, we present the hypothesis that, paradoxically, awareness efforts are contributing to this reported increase in mental health problems. We term this the prevalence inflation hypothesis. First, we argue that mental health awareness efforts are leading to more accurate reporting of previously under-recognised symptoms, a beneficial outcome. Second, and more problematically, we propose that awareness efforts are leading some individuals to interpret and report milder forms of distress as mental health problems. We propose that this then leads some individuals to experience a genuine increase in symptoms, because labelling distress as a mental health problem can affect an individual's self-concept and behaviour in a way that is ultimately self-fulfilling. For example, interpreting low levels of anxiety as symptomatic of an anxiety disorder might lead to behavioural avoidance, which can further exacerbate anxiety symptoms. We propose that the increase in reported symptoms then drives further awareness efforts: the two processes influence each other in a cyclical, intensifying manner. We end by suggesting ways to test this hypothesis and argue that future awareness efforts need to mitigate the issues we present. [ABSTRACT FROM AUTHOR]

Background: While the recent CARMENA trial evaluated upfront cytoreductive nephrectomy (CN) among patients treated with immediate subsequent systemic therapy for metastatic renal cell carcinoma (mRCC), the role of CN in patients not immediately requiring systemic therapy remains to be determined.Objective: To describe the oncologic outcomes of patients with de-novo synchronous mRCC who underwent CN +/- metastasis-directed therapy (MDT) and subsequent surveillance without planned immediate post-CN systemic therapy.Design, Setting, Participants: Adults who underwent CN for unilateral, sporadic mRCC between 1996 and 2016 without immediate postoperative systemic therapy were identified using the prospectively-maintained Mayo Clinic Nephrectomy Registry. Co-primary outcomes were survival free of systemic therapy or death and overall-survival.Results: Of 156 patients who met inclusion criteria for study, 37 (24%) patients were managed after CN with surveillance alone and 119 (76%) underwent MDT. Seventy-two patients ultimately initiated systemic therapy at a median of 0.7 years (IQR 0.3-1.7). Median follow-up among survivors was 6.2 years (IQR 4.4-9.5), during which time 133 patients died. At 1, 3, and 5 years, survival free of systemic therapy or death rates were 47%, 21% and 14% and overall-survival rates were 69%, 37%, and 28%.Conclusion: Among carefully selected patients managed with surveillance after CN +/- MDT, approximately half may avoid systemic therapy for 1 year, with a subset achieving long-term survival free of systemic therapy or death. Having a single metastatic site and disease amenable to complete metastasectomy are features of patients who might be well served with upfront CN +/- MDT. [ABSTRACT FROM AUTHOR]- Published

Objectives: To evaluate the feasibility of performing a robot-assisted radical prostatectomy (RARP) as an outpatient procedure while maintaining patient satisfaction and safety. Herein we report our experience, selection criteria, and discharge criteria for outpatient RARP. Methods: We performed a prospective study with 11 patients undergoing extraperitoneal RARP. These patients were counseled before the procedure that they would go home the same evening of the procedure. The patients were then surveyed by a third party shortly after they returned home, using the Patient Judgement System-24, a previously validated instrument for patient satisfaction. Sociodemographic data, comorbidities, and outcomes were collected for analysis. Results: All patients were successfully discharged the same day of surgery. Mean patient age was 62.2 years with a mean body mass index of 26 kg/m2. Mean operative time was 117.6 minutes, console time was 76.7 minutes, and estimated blood loss was 168.2 mL. Mean indwelling catheter time was 7.5 days. No complications occurred in this series of patients. Satisfaction was unanimously high in all patients surveyed, with most scores over 90% on the Patient Judgement System-24. No patient reported any ill effects from the shortened stay or felt rushed to leave the hospital. Conclusions: The early experience with extraperitoneal RARP as a same day surgery is promising. Preoperative patient counseling and selection is paramount. Patient satisfaction is not adversely affected by the shortened stay. Surgeon experience, assessment of intraoperative findings, and adequate postoperative assessment are essential. [Copyright &y& Elsevier]

Objective: To identify the incidence of venous thromboembolism (VTE) risk factors, postoperative VTE, and to assess the morbidity of perioperative pharmacologic VTE prophylaxis in men undergoing inflatable penile prosthesis (IPP) surgery.Methods: We retrospectively reviewed 215 patients undergoing IPP surgery between July 2017 and June 2019. Univariate and multivariate statistical analyzes were performed to assess pre-operative Caprini risk score and compare post-operative day 0 scrotal drain output, scrotal hematoma formation, and VTE in men who received subcutaneous heparin (SqH) vs those who did not receive SqH.Results: Of 215 IPP patients, 84% were classified as high or highest risk for VTE utilizing the Caprini risk score. A total of 119 (55%) received perioperative SqH with or without additional anti-thrombotics. Post-operative day 0 scrotal drain output was higher in those who received SqH compared to those who did not receive SqH, 99.9 mL vs 75.6 mL, respectively (P = .001). Minor scrotal hematomas occurred in similar rates in patients who received perioperative SqH vs those who did not, 3.8% vs 6.3%, respectively (P = .38). Similar results were found on subgroup analysis when eliminating patients who received SqH concurrently with other anti-thrombotics. The overall rate of postoperative VTE was 0.9%. No post-operative infections occurred.Conclusion: Patients undergoing IPP surgery are at elevated risk for VTE. To our knowledge, this is the first study showing SqH use in the perioperative IPP surgery setting is safe when used in conjunction with a scrotal drain. Preoperative VTE risk stratification may be performed and can be used to guide clinical decision making regarding pharmacologic prophylaxis. [ABSTRACT FROM AUTHOR]- Published

Radium-223 has been recommended for patients with bone-dominant metastatic prostate cancer. The addition of second-generation hormone therapy (2nd HT) to radium-223 with mCRPC has been attempted, but its benefit has not yet been elucidated. Herein, we aim to investigate the potential benefit of the concomitant use of 2nd HT with radium-223 in the third-line setting. In a single-institution retrospective study, we identified 57 patients with bone-dominant mCRPC that were treated with radium-223 as a third-line therapy, either alone or with concomitant 2nd HT. Survival outcomes were assessed based on 3-year overall survival (OS). Mean (±SD) age was 70.1 (±8.2) yrs., median (IQR) primary Gleason Score was 9 (7-9), median (IQR) pre-radium-223 ALK-P was 91 (67-117) and median (IQR) pre-radium-223 PSA was 21.1 (7.6-65.5) ng/ml. Median (IQR) number of Radium-223 cycles was 6 (5-6). 32 patients received radium-223 alone, and 25 patients received radium-223 with concomitant 2nd HT (n = 17 enzalutamide, n = 8 abiraterone). 3-year OS for radium-223 alone was 10% versus 25% and 10% with concomitant abiraterone or enzalutamide, respectively. There was no significant difference in 3-year OS between patients that received radium-223 alone versus those that received concomitant 2nd HT (Figure 1). Adding 2nd HT to radium-223 in the third-line setting did not provide any survival benefit in our retrospective study. Further prospective studies are warranted. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the impact of diabetes and obesity on artificial urinary sphincter (AUS) outcomes.Materials and Methods: From 1987 to 2011, men with available diabetes and body mass index (BMI) information (568 of 954) undergoing primary AUS placement at our institution were evaluated. The incidence of all-cause reintervention, mechanical failure, atrophy, and erosion or infection was assessed using the Kaplan-Meier method. Multivariable analyses evaluated the association between clinical characteristics and AUS outcomes.Results: In total, 90 (16%) men had diabetes. Median follow-up among alive men without AUS event was 5.9 years. Diabetics had a greater 5-year incidence of erosion/infection (13% vs 8%; P = .025). On multivariable analysis, diabetes was independently associated with an increased risk of erosion/infection (hazard ratio [HR] = 2.26; P = .02); whereas greater BMI was associated with a reduced risk of erosion or infection (obese: HR = 0.39; P = .02; overweight: HR = 0.57; P = .07). Accordingly, in diabetics, greater average postoperative glucose level (176 mg/dL vs 153 mg/dL; P = .04) and use of nonantibiotic coated devices (13 of 62 vs 1 of 28; P = .035) was associated with a greater incidence of erosion or infection. There was no difference in social continence (≤1 pad/day) (45% vs 57%; P = .29) or high-level satisfaction (95% vs 90%; P = .43) among diabetics vs nondiabetics. However, with greater BMI (<25, 25 to <30, and ≥30), there was a decrease in ≤1 pad/day usage (62% vs 61% vs 49%; P = .02).Conclusion: We found that the presence of diabetes was independently associated with a 2.3-fold increased risk of AUS erosion or infection. These findings warrant the consideration of additional periprocedural measures to reduce the risk of this devastating complication. [ABSTRACT FROM AUTHOR]- Published

Introduction and Objective: Urosymphyseal fistula (UF) with osteomyelitis most commonly occurs as a result of prostate cancer and benign prostate hyperplasia therapy. UF presentation typically includes debilitating pelvic pain exacerbated with ambulation. Traditional management required open surgical genitourinary (GU) reconstruction with pubectomy leading to significant morbidity. However, progressive utilization of robotic approaches and advances in holmium laser technology has led to a less invasive alternative. Herein, we present our series of robotic-assisted holmium laser debridement of pubic osteomyelitis in the setting of UF.Methods: After physical exam, all patients presenting with concerns for GU fistula and osteomyelitis are evaluated with BMP, CBC, serum albumin, urine culture, and cystoscopy. Patients often present with previously obtained CT abdomen/pelvis. However, all patients presenting with concerns of pubic osteomyelitis should undergo a MRI of the pelvis to characterize the pubis. Specific indications for holmium laser debridement of the pubic bone include: 1) history of sacral insufficiency fractures which eliminate management with partial pubectomy due to risk of pelvic ring instability and 2) mild osteomyelitis which can be managed with debridement. The patient is placed in dorsal lithotomy position. After the robot is docked, the space of retzius is developed and the fistula is resected down to the pubic bone. The symphysis is debrided using the Cobra grasper followed by holmium laser debridement at 2J and 50Hz settings. Appropriate GU reconstruction versus urinary diversion is then performed per clinical judgement. Antibiotic beads are then placed in the symphyseal defect. If available, an interposition flap may be advanced between the urethra/bladder and symphysis.Results: In our series of four patients, all patients underwent successful robotic pubic symphyseal debridement and were discharged without experiencing a major complication. At follow up (7-16 months) there have been no fistula recurrence or recurrent episodes of osteomyelitis.Conclusion: Robotic assisted pubic symphyseal debridement with a holmium laser is feasible, safe, and efficacious in this small series with short follow up. This approach represents a minimally invasive alternative to open pubectomy while minimizing incisions and overall morbidity. Additional long-term data is necessary before wide spread adoption of this approach. [ABSTRACT FROM AUTHOR]- Published
