Abstract
BACKGROUND Enfortumab vedotin is a novel antibody-drug conjugate used as a third-line therapy for the treatment of urothelial cancer. We aimed to elucidate the effect of enfortumab vedotin-related peripheral neuropathy on its efficacy and whether enfortumab vedotin-induced early electrophysiological changes could be associated with peripheral neuropathy onset. METHODS Our prospective multicenter cohort study enrolled 34 patients with prior platinum-containing chemotherapy and programmed cell death protein 1/ligand 1 inhibitor-resistant advanced urothelial carcinoma and received enfortumab vedotin. The best overall response, progression-free survival, overall survival, and safety were assessed. Nerve conduction studies were also performed in 11 patients. RESULTS The confirmed overall response rate and disease control rate were 52.9% and 73.5%, respectively. The median overall progression-free survival and overall survival were 6.9 and 13.5 months, respectively, during a median follow-up of 8.6 months. The patients with disease control had significantly longer treatment continuation and overall survival than did those with uncontrolled disease. Peripheral neuropathy occurred in 12.5% of the patients. The overall response and disease control rates were 83.3% and 100%, respectively: higher than those in patients without peripheral neuropathy (p = 0.028 and p = 0.029, respectively). Nerve conduction studies indicated that enfortumab vedotin reduced nerve conduction velocity more markedly in sensory nerves than in motor nerves and the lower limbs than in the upper limbs, with the sural nerve being the most affected in the patients who developed peripheral neuropathy (p = 0.011). CONCLUSION Our results indicated the importance of focusing on enfortumab vedotin-induced neuropathy of the sural nerve to maximize efficacy and improve safety.

Abstract
OBJECTIVES To assess whether the coronavirus disease (COVID-19) pandemic affected the outcomes of robot-assisted radical prostatectomy (RARP) and urologists' treatment behaviors. METHODS We retrospectively examined the medical records of 208 patients who had undergone RARP between August 2017 and December 2022. We compared the rate of preoperative androgen deprivation therapy (ADT), waiting period for RARP, patients' baseline characteristics and quality of life (QOL), proportion of adverse pathology on the RARP specimen, rate of Gleason grade group upgrading from biopsy to the RARP specimen, and prostate-specific antigen (PSA) recurrence-free survival between the pre-pandemic and pandemic groups. RESULTS The rate of preoperative ADT was significantly higher during than before the COVID-19 pandemic (13.7% vs. 1.9%; p = 0.002). The baseline physical and mental QOL scores did not differ significantly between the groups. The proportion of D'Amico low-risk patients was significantly lower (13.6% vs. 1.2%, p = 0.005) and waiting period for RARP was significantly shorter (median 3.5 months vs. 4.0 months, p = 0.016) in the pandemic group than in the pre-pandemic group. There was no significant difference in the proportion of adverse pathology between the groups (p = 0.104); however, the upgrading rate was significantly higher in the pre-pandemic group (p = 0.002). There was no significant difference in PSA recurrence-free survival between the groups (log-rank, p = 0.752). CONCLUSIONS The COVID-19 pandemic did not adversely affect the oncologic outcomes of RARP and QOL before RARP. However, it caused urologists to increase the use of preoperative ADT and to reserve RARP for higher-risk cases.

Abstract
Introduction There have been reports of surgery for residual ureteral tumors, most of them involved open surgeries. Herein, we report a case of retroperitoneal scopic left ureteral resection and partial cystectomy, performed by placing a fluorescent ureteral catheter in the residual ureter. Case presentation A 79-year-old man was admitted to our hospital with a chief complaint of gross hematuria. He had undergone transperitoneal left radical nephrectomy due to angiomyolipoma 20 years ago. Computed tomography and Magnetic resonance imaging revealed a solid tumor in the left residual ureter. Retroperitoneal scopic residual ureterectomy has been performed. During the operation, a fluorescent ureteral catheter proved to be very helpful in detecting the ureter. Conclusion A fluorescent ureteral catheter is considered to be a useful tool in laparoscopic surgery, especially in cases where identification of the ureter is expected to be difficult, such as the residual ureter in this case.

Abstract
OBJECTIVE To investigate the prevalence of frailty and its effects on cancer-related fatigue and quality of life among patients with prostate cancer. METHODS In this cross-sectional study, questionnaires were administered to 254 outpatients who visited the Department of Urology at Kagawa University Hospital for prostate cancer; finally, 108 outpatients were analyzed. Frailty, cancer-related fatigue and quality of life were assessed using the G8 screening tool, Japanese version of the Brief Fatigue Inventory and Japanese version of the Short Form 8 Health Survey, respectively. We defined frailty based on a score ≤14 points and divided the patients into frailty and no-frailty groups. We also compared the severity of cancer-related fatigue and quality of life between groups. RESULTS The prevalence of frailty among 108 outpatients was 63%. Older age correlated with frailty severity (P = 0.0007) but not cancer-related fatigue severity (P = 0.2391). The proportion of patients on treatment or with metastasis was not significantly different between groups. The frailty group had higher cancer-related fatigue severity (P = 0.004) and decreased levels of general activity, mood, walking ability, normal work and enjoyment of life, especially on the Brief Fatigue Inventory subscale. The frailty group had lower physical and mental quality of life than the no-frailty group or general population. CONCLUSIONS The frailty rate for these patients increased with age, exceeding 60% regardless of the treatment status, and was associated with worsened cancer-related fatigue severity and reduced quality of life. Our study highlights the importance of assessing frailty when selecting treatment, especially in older patients.

Abstract
BACKGROUND The efficacy of photodynamic diagnosis using 5-aminolevulinic acid during transurethral resection of bladder tumors has been demonstrated, albeit with limited information regarding its side effects. This study aimed to clarify the impact of oral 5-aminolevulinic acid on perioperative nausea and vomiting (NV) for the first time in a real-world clinical practice setting. METHODS Patients who underwent transurethral surgery at Kagawa University between April 2017 and March 2020 were included. Perioperative NV and antiemetic use status were prospectively assessed and compared between the patients who received oral 5-aminolevulinic acid and those who did not. Additionally, univariate and multivariate analyses were performed for predicting postoperative nausea and vomiting. RESULTS Of 214 patients, 74 (34.6%) received oral 5-aminolevulinic acid preoperatively. The proportions of preoperative NV and antiemetic use in the patients who received 5-aminolevulinic acid were 9.5% and 4.1%, respectively, and higher than in those who did not (0% and 0%; P < 0.01 and P = 0.04, respectively). Postoperative NV (25.7%) and antiemetics use (8.0%) ratios in the patients who received 5-aminolevulinic acid were significantly different from those in the non-users group (3.6% and 2.1%, P < 0.01 and P < 0.01, respectively). Although no differences in risk factors were found for postoperative NV between the two groups, multivariate analyses indicated 5-aminolevulinic acid use as an independent predictive factor for postoperative NV (odds ratio, 11.5; 95% confidence interval, 3.98-33.3; P < 0.01). CONCLUSIONS Our study clearly showed that oral administration of 5-aminolevulinic acid was associated with perioperative NV even without risk factors, highlighting the need for addressing its application.

Abstract
OBJECTIVE This study conducted a national questionnaire survey of Japanese urologists from a treatment perspective for older patients with prostate cancer. METHODS A questionnaire was distributed to 922 teaching hospitals of the Japanese Urological Association. Questionnaire items included years of urologist experience, gender, workplace, treatment equipment owned, daily specialty practice area, urological cancer specialty, treatment reference items for older adults, upper age limit for radical treatment, medication, and two hypothetical cases of Gleason grade group 2 prostate cancer with or without oligometastasis. RESULTS In total, 1732 questionnaires were analyzed, with responses evenly distributed across all age groups. Workplaces included general hospitals (49.4%), university hospitals (40.3%), and cancer centers (4.2%). Performance status was the most frequently mentioned treatment-related item, followed by comorbidities and cognitive function. In addition, geriatric assessment was used by only 13.3% of respondents. No upper age limit was found for total prostatectomy, brachytherapy, and external beam radiation. Anti-androgens, androgen receptor-axis-targeted agents, chemotherapy, poly ADP ribose polymerase inhibitors, and immune-checkpoint inhibitors were selected by 6.8%, 35.6%, 47.3%, 89%, 62.8%, 24.7%, 41.9%, and 41.7% of the respondents, respectively. Response rates for administration of hormone therapy for hypothetical cases of Gleason grade group 2 prostate cancer with or without oligometastases were 96.8% and 61.2%, respectively. CONCLUSIONS Less than 15% of urologists used geriatric assessments. Several responded that they would set age limits for highly invasive radical and systemic therapies.

Abstract
OBJECTIVE To conduct a national questionnaire survey of Japanese urologists on active surveillance (AS) for low- and intermediate-risk prostate cancer (PCa). METHODS A questionnaire was sent to 922 Japanese Urological Association Teaching Base Hospitals. The items included were years of experience as a urologist, sex, workplace, treatment equipment owned, specialty area of daily practice, specialty area of urological cancer, and six hypothetical cases of AS. The cases were categorized by the following Gleason scores: 3 + 3 low risk of PCa, 3 + 4 intermediate risk, and 4 + 3 intermediate risk, with or without comorbidities for each case. Comorbidities were defined as cardiovascular diseases or illnesses warranting anticoagulant therapy. RESULTS Altogether, 1962 questionnaires were analyzed. Responses were almost equally distributed among all age groups. Workplaces included general hospitals (49.4%), university hospitals (40.3%), and cancer centers (4.2%). Percentages of proposed AS for low risk/no comorbidity, low risk/with comorbidity, intermediate-risk 3 + 4/no comorbidity, intermediate risk 3 + 4/with comorbidity, intermediate risk 4 + 3/no comorbidity, and intermediate risk 4 + 3/with comorbidity were 90.5%, 90%, 39.5%, 48.7%, 15%, and 22%, respectively. Analysis of the correspondents' backgrounds showed that the more the urologists' years of experience, the less they were to advise AS of low-risk patients. In the presence of comorbidities, urologists across all age groups tended to propose AS, even in the same Gleason grade group. Cancer center urologists recommended AS more often than their counterparts at general and university hospitals. CONCLUSIONS Approximately 40% of urologists proposed AS for intermediate-risk cases, confirming that AS for intermediate-risk patients is being considered in Japan.

Abstract
327 Background: Physicians' attitudes toward elderly prostate cancer patients in Japan remain unknown. So, we conduct a national questionnaire survey of Japanese urologists from a treatment perspective for elderly patients with prostate cancer. Methods: A questionnaire was sent to 922 Japanese urological association teaching base hospitals. The following items were included: years of experience as a urologist, gender, workplace, treatment equipment owned, specialty area of daily practice, specialty area of urological cancer, reference items for treatment of the elderly, upper age limit for radical treatment, medication, and two hypothetical cases of Gleason grade Group 2 prostate cancer with or without oligometastasis. For examined the correlation between experience for urological practice and the answer, “not considering the upper age limit”, Cochran-Armitage trend test was used. For comparison of the rate of answering with “not considering the upper age limit” between variables, z-tests were conducted repeatedly and Bonferroni adjustments were made. In this analysis, the statistical significance was set at a P-value <0.05. Results: Altogether, 1,732 questionnaires were analyzed. The responses were almost equally distributed among all age groups. Workplaces included general hospitals (49.4%), university hospitals (40.3%), and cancer centers (4.2%). Performance status was the most frequently referenced item in treating the elderly, followed by the presence of comorbidities and cognitive function. Furthermore, 13.3% of respondents used the geriatric assessment. There was no upper age limit for total prostatectomy, brachytherapy, and external radiation therapy. Antiandrogens, androgen receptor-axis-targeted agents, chemotherapy, PARP inhibitors, and immune-checkpoint inhibitors were selected by 6.8%, 35.6%, 47.3%, 89%, 62.8%, 24.7%, 41.9%, and 41.7% of the respondents, respectively. The answers for the administration of hormone therapy for hypothetical cases of Gleason grade Group 2 prostate cancer with or without oligometastasis were 96.8% and 61.2%, respectively. The answers for the administration of hormone therapy for hypothetical cases of Gleason grade Group 2 prostate cancer with or without oligometastasis were 96.8% and 61.2%, respectively. Conclusions: Fewer than 10% of urologists used geriatric assessments. Many urologists responded that they would set age limits for highly invasive radical and systemic therapies. [Table: see text]

Abstract
OBJECTIVE this study aimed to evaluate the active surveillance continuation period, treatment intervention rate and health-related quality of life in younger patients. METHODS we prospectively conducted a health-related quality of life survey of patients enrolled in the Prostate Cancer Research International: Active Surveillance-JAPAN study at Kagawa University between January 2010 and December 2020. Health-related quality of life was assessed by mail using a validated Japanese version of the Short-Form 8 Health Survey and Expanded Prostate Cancer Index at active surveillance enrolment and annually thereafter until discontinuation of active surveillance. We divided the patients into two groups, younger (aged <65 years) and older (aged ≥65 years), and compared the two groups. RESULTS of the 84 patients, 22 were in the younger group. The active surveillance continuation period was shorter in the younger group than in the older group. The 3-year treatment intervention rate was higher in the younger group than in the older group. The majority of the reasons for definitive treatment were related to the protocol, which was similar in both groups (80 versus 76%). The sexual summary scores at active surveillance enrolment were higher in the younger group than in the older group. During active surveillance, the younger group and the older group showed no deterioration in all health-related quality of life scores compared with the scores at the enrolment of active surveillance. CONCLUSIONS patient-reported health-related quality of life survey indicated that the health-related quality of life of younger Japanese patients was maintained over time during active surveillance, similar to that of older patients.

Abstract
Background The Paris System (TPS) for reporting urinary cytology differs from conventional systems (CS) in that it focuses on the diagnosis of high-grade urothelial carcinoma (HGUC). This study investigated the impact of TPS implementation on the diagnostic accuracy of HGUC by comparing it with our institutional CS. Methods A total of 649 patients who underwent transurethral resection of bladder tumor (TURBT) between January 2009 and December 2020 were included in this study. Our institution adopted TPS to report urinary cytology in February 2020. The diagnostic accuracy of HGUC in preoperative urinary cytology was compared with the presence or absence of HGUC in resected specimens of TURBT before and after TPS implementation. Results After implementing TPS in urinary cytology, 89 patients were reviewed and compared with 560 patients whose urinary cytology was diagnosed by CS. TPS and CS for detecting HGUC had 56.0% and 58.2% sensitivity, 97.8% and 91.2% specificity, and 93.3% and 87.9% positive predictive values, respectively. There were no significant differences between TPS and CS in terms of sensitivity, specificity, and positive predictive value for HGUC (P = 0.83, 0.21, 1.00). On the other hand, the negative predictive value for HGUC using TPS was 80.0%, which was significantly higher than that of CS (66.4%, P = 0.04) The multivariate logistic regression analysis indicated that not using TPS was one of the independent predictive factors associated with false-negative results for HGUC (odds ratio, 2.26; 95% confidence interval, 1.08–4.77; P = 0.03). Conclusion In instances where urinary cytology is reported as negative for HGUC by TPS, there is a low probability of HGUC, indicating that TPS has a potential diagnostic benefit.

Abstract
BACKGROUND 5-aminolevulinic acid is a protoporphyrin IX precursor used for photodynamic diagnosis. We aimed to clarify the therapeutic benefits of orally administered 5-aminolevulinic acid for photodynamic diagnosis in transurethral resection for non-muscle-invasive bladder cancer in a real-world setting. METHODS From January 2009 to December 2020, patients with non-muscle-invasive bladder cancer who have undergone visually complete resection by initial transurethral surgery were included. Histopathologically confirmed residual and intravesical recurrent bladder cancer was retrospectively investigated and compared with transurethral resection using photodynamic diagnosis and conventional white light. RESULTS One hundred and fifteen patients who underwent photodynamic diagnosis-transurethral resection were compared with 346 patients who underwent white light-transurethral resection. The second transurethral resection revealed that the proportion of residual T1 and Ta bladder cancer was lower in the photodynamic diagnosis group than in the white light group (10.3% vs. 33.8%, P=0.001). Additionally, the proportion of intravesical recurrence was lower in the photodynamic diagnosis group than in the white light group (9.6% vs. 41.9%, P<0.001). Using 5-aminolevulinic acid-photodynamic diagnosis during transurethral resection of bladder tumor improved the cumulative intravesical recurrence-free survival (log-rank test: P<0.001). Furthermore, multivariate analyses indicated that not using 5-aminolevulinic acid-photodynamic diagnosis was an independent predictive factor for residual bladder cancer (odds ratio, 6.16; 95% confidence interval, 2.10-18.0; P<0.001) and intravesical recurrence (hazard ratio, 2.01; 95% confidence interval, 1.05-3.83, P=0.034). CONCLUSIONS Introducing 5-aminolevulinic acid-photodynamic diagnosis into transurethral resection reduces residual bladder cancer and improves the cumulative intravesical recurrence-free survival in patients with non-muscle-invasive bladder cancer, indicating its possible therapeutic benefits.

Abstract
We assessed whether the severity of anastomotic urinary leakage detected during routine cystourethrography after robot-assisted laparoscopic prostatectomy (RALP) affects urinary continence recovery. Around 302 patients who underwent RALP between August 2013 and May 2019 were included retrospectively. According to routine cystourethrographic findings obtained on the sixth or eighth postoperative day, which indicated leakage severity, patients were divided into three groups: no-leakage, grade 1 (linear shaped leakage, but not spreading), and grade 2 (spreading strip-shaped leakage). The preoperative factors and intraoperative factors were compared between no-leakage and leakage group (grade 1 and grade 2). Continence recovery was compared between the three groups. Continence recovery was defined as no pad used or one security pad used in a day. Cystourethrography revealed anastomotic urinary leakage in 44 patients (14.5%), of which 20 patients (6.6%) had grade 1 leakage and 24 patients (7.9%) had grade 2 leakage. On multivariate logistic regression analysis, the only significant predictor for urethrovesical anastomotic urinary leakage on cystourethrography following RALP was intraoperative anastomotic leakage (OR 5.306; 95% CI 1.530-18.398, p = 0.009). Continence recovery rates for no-leakage, grade 1 leakage, and grade 2 leakage groups were 11%, 20%, and 25% after 1 month (P = 0.131); 25%, 25%, and 45.8% after 3 months (P = 0.474); 44.6%, 55%, and 60.8% after 6 months (P = 0.184); and 63.1%, 87.5%, and 78.2% after 12 months (P = 0.095), respectively. In conclusion, urinary leakage in urethrovesical anastomosis, even at its severity, had no negative effects on continence recovery after RALP.

Abstract
Mycophenolate mofetil is a key immunosuppressant that is metabolized into mycophenolic acid (MPA). The prognostic impact of MPA-focused therapeutic drug monitoring on allograft prognosis has not been determined in kidney transplant recipients with diabetes. In this study, we assessed the pharmacokinetics of MPA and allograft prognosis in recipients with diabetes. This study retrospectively analyzed 64 adult kidney transplant recipients. MPA blood concentration data (e.g., the time to the maximum concentration (Tmax), and the area under the concentration–time curve from 0 to 12 h (AUC0–12)) were collected at 3 weeks and 3 months after kidney transplantation. Of the 64 recipients, 15 had pre-existing diabetes. At 3 months after kidney transplantation, the Tmax of MPA was significantly longer in recipients with diabetes (mean (standard deviation): 2.8 (2.1) h) than in recipients without diabetes (1.9 (1.1) h, p = 0.02). However, the allograft estimated glomerular filtration rate and acute rejection rate, including borderline change, did not differ according to the diabetes status in patients with adjusted AUC0–12 of MPA within the target range. In conclusion, a longer Tmax of MPA was observed in recipients with diabetes; however, acceptable allograft prognosis was observed in kidney transplant recipients with diabetes and a sufficient AUC0–12 of MPA.

Abstract
UNLABELLED Pre-existing inflammation, corticosteroid therapy, periapical periodontitis, longer duration of denosumab therapy, and female sex were significantly associated with an increased risk of denosumab-related osteonecrosis of the jaw after tooth extraction in patients with cancer on oncologic doses of denosumab. A short drug holiday did not protect against this complication. INTRODUCTION This study retrospectively investigated the relationship between various risk factors, including brief discontinuation of denosumab, and development of denosumab-related osteonecrosis of the jaw (DRONJ) after tooth extraction in patients with cancer who were receiving oncologic doses of this agent. METHODS Data were collected on demographic characteristics, duration of denosumab therapy, whether or not denosumab was discontinued before tooth extraction (drug holiday), duration of discontinuation, presence of pre-existing inflammation, and whether or not additional surgical procedures were performed. Risk factors for DRONJ after tooth extraction were evaluated by univariate and multivariate analyses. RESULTS A total of 136 dental extractions were performed in 72 patients (31 men, 41 women) with cancer who were receiving oncologic doses of denosumab. Post-extraction DRONJ was diagnosed in 39 teeth (28.7%) in 25 patients. Tooth extraction was significantly associated with development of DRONJ only in patients with pre-existing inflammation (odds ratio [OR] 243.77), those on corticosteroid therapy (OR 73.50), those with periapical periodontitis (OR 14.13), those who had been taking oncologic doses of denosumab for a longer period (OR 4.69), and in women (OR 1.04). There was no significant difference in the occurrence of DRONJ between patients who had a drug holiday before tooth extraction and those who did not. CONCLUSIONS These findings suggest that inflamed teeth should be extracted immediately in patients with cancer who are receiving oncologic doses of denosumab. Drug holidays have no significant impact on the risk of DRONJ.

Abstract
Abstract
Background
For cardiac resynchronization therapy (CRT), patients with chronic heart failure (HF) and wide (>150msec) QRS duration (QRSd) received class I/A indication. However, its beneficial effect seemed to be limited for those with mid- (120–150msec) QRSd. Recent studies demonstrated that QRSd normalized to left ventricular end-diastolic volume (QRSd/ LVEDV) improved prediction of clinical outcome in patients with CRT. Therefore, we sought to investigate predictive value of QRSd/LVEDV for responding to CRT in patients with mid-QRSd.
Methods
This was retrospective multi-center observational cohort study. A total 506 consecutive patients who underwent CRT implantation in Tohoku University Hospital and National Cerebral and Cardiovascular Center were evaluated. Exclusion criteria were QRSd less than 120ms, upgrade procedures from other implanted non-CRT devices and bradycardia requiring pacing. We evaluated clinical variables, data of electrocardiogram and transthoracic echocardiography at baseline and 6 months after CRT implantation. Primary endpoint was a HF hospitalization after CRT implantation. Distribution of free from HF hospitalization during follow-up was calculated using Kaplan-Meier curves, and the effects of covariate on the time to endpoint were investigated using a Cox proportional hazards model.
Results
After 199 patients were excluded based on exclusion criterion, remaining 307 patients were included for the analysis. Mean age was 62±14 [SD] years, and 238 (77%) were male. Mean LVEF and LVEDV were 25±9% and 234±82ml, respectively, and 24% of patients had ischemic etiology of HF. During the median 948 days of follow-up, CRT patients with mid QRSd (n=126; 136±10msec), as compared with those with wide QRSd (n=181; 174±17msec), tended to have higher incidence of HF hospitalization (Wilcoxon p=0.03). Multivariate analysis showed that QRSd and QRSd/LVEDV were significant predictors for HF hospitalization in CRT patients with mid QRSd, and cut-off values (137msec of QRSd and 0.65 of QRSd/LVEDV), which was calculated by receiver operative curve analysis, was used for risk stratification. QRSd<137msec was significant negative predictors for HF hospitalization (p=0.005), and Mid-QRSd patients with QRSd≥137msec demonstrated equivalent clinical outcome with those with wide QRSd. Moreover, patients with QRSd/LVEDV≥0.65 tended to have lower incidence of HF hospitalization as compared with those without it among patients with QRSd<137msec (n=64, Figure).
Conclusion
The present study demonstrates that QRSd normalized to left ventricular end-diastolic volume (QRSd/ LVEDV) could be clinical value in predicting outcome in CRT patients with mid-QRSd. These findings indicate normalized QRSd reflects myocardial conduction properties and contribute to risk stratification.

Abstract
Purpose To investigate the association between urine culture before transperineal prostate biopsy and post-biopsy febrile urinary tract infection (fUTI). Patients and Methods We retrospectively reviewed 307 patients who underwent urine culture before transperineal prostate biopsy between April 2017 and September 2020. Patients with indwelling urinary catheters (n=7) were excluded. Urine culture was performed 1–3 days before the biopsy, and all patients received prophylactic cefazolin regardless of culture results. A urine culture was defined as positive if cell density was more than 1×105 colony-forming units per mL. Baseline characteristics and the incidence of post-biopsy fUTI were compared between patients showing positive pre-biopsy culture results and those showing negative findings. Results Out of 300, seven patients (2.3%) had positive urine culture results before the biopsy. Age (p=0.077); prostate-specific antigen at diagnosis (p=0.267); prostate volume (p=0.78); number of biopsy cores (p=0.277); percentage of patients testing positive for cancer on biopsy (p=0.71); and percentages of patients with a history of biopsy (p>0.999), diabetes mellitus (p=0.604), and immunosuppressive medication use (p>0.999) were similar between the two groups. No patient in the positive urine culture group had post-biopsy fUTI. However, 1.7% (five patients) of the negative urine culture group had the disease (p>0.999) (four patients with prostatitis and one with pyelonephritis). Among them, two patients were diagnosed by urine culture at the time of post-biopsy fUTI. Conclusion In asymptomatic patients, positive pre-biopsy cultures were not associated with the development of post-biopsy fUTI.

Abstract
INTRODUCTION We examined the prevalence, pathological findings, and oncological outcomes of incidental bladder cancer found on cystoscopy among patients eligible for prostate biopsy (PB). METHODS We retrospectively reviewed 803 patients who underwent cystoscopy prior to PB between January 2010 and September 2020. In cases of bladder tumor-like findings on cystoscopy, biopsy or transurethral resection of the bladder tumor was performed. The primary and secondary outcomes were the prevalence of incidental bladder cancer and pathological and oncological outcomes of incidental bladder cancer, respectively. RESULTS Incidental findings were observed in 31/803 patients (3.9%). Bladder tumor-like findings were found in 24/803 patients (3%), while 9/803 patients (1.1%) were pathologically diagnosed with urothelial carcinoma. The stage and grade of incidental bladder cancer were pTa in 8/9 patients and pT1 in 1/9 and low grade in 8/9 and high in 1/9, respectively. The median tumor size of the papillary pedunculated type was 0.5 cm. At 26-month median follow-up, no recurrence was observed. CONCLUSION Cystoscopy during PB may yield incidental bladder cancer findings, although the prevalence is very low. Incidental bladder cancer was of low stage and grade, which seemed unrelated to survival. Moreover, performing routine cystoscopy in conjunction with PB is not recommended as it may lead to overdiagnosis of low-risk bladder cancer.

Abstract
6p21 translocation renal cell carcinoma (RCC) harboring TFEB gene fusion is a newly classified microphthalmia-associated transcription (MiT) factor-family translocation RCC with early onset. We present a case of 78-year-old man with a 6p21 translocation RCC that was diagnosed after partial nephrectomy for an incidental renal tumor on computed tomography (CT). Unenhanced CT showed a 20 mm, mildly low-density mass in the right kidney. Contrast-enhanced CT showed a heterogeneous and prolonged, mild enhancement in the tumor. On magnetic resonance imaging, the tumor showed iso-intensity within the renal parenchyma on T1-weighted-imaging (WI), low intensity on T2WI, and no restricted diffusion with low signal on diffusion-weighted imaging, with no clear tumor pseudocapsule. Fat poor angiomyolipoma and non-clear cell RCC were listed as differential diagnoses. Robot-assisted partial nephrectomy was successfully performed. Fluorescence in situ hybridization study of the resected tumor confirmed TFEB gene break, and the patient was diagnosed with a 6p21 translocation RCC. The patient is doing well without recurrence after 2.5 years of follow-up. Our patient is the oldest patient reported in previous literature.

Abstract
OBJECTIVE To elucidate the therapeutic benefits of using a surgical checklist during transurethral resection for non-muscle-invasive bladder cancer. METHODS A nine-item surgical checklist was established in January 2016 to assess disease risk and resection adequacy, and it was prospectively implemented into clinical practice. Patients diagnosed with non-muscle-invasive bladder cancer who underwent complete resection from January 2009 to August 2019 were included in this study. The presence of detrusor muscle in the transurethral resection specimen and the intravesical recurrence-free survival were compared between patients who underwent transurethral resection before and after surgical checklist implementation. RESULTS A total of 125 patients who underwent transurethral resection after surgical checklist implementation were reviewed and compared with 125 patients who underwent transurethral resection before surgical checklist implementation. The use of the surgical checklist led to an increase in the proportion of transurethral resection specimens containing detrusor muscle (92% vs 69.6%, P < 0.01) and a decrease in the recurrence rate (19.2% vs 49.6%, P < 0.01). Multivariate analysis showed that transurethral resection without a surgical checklist was an independent predictive factor influencing the absence of detrusor muscle in the transurethral resection specimen (odds ratio 4.78, P < 0.01) and intravesical recurrence (hazard ratio 1.92, 95% confidence interval 1.14-3.23; P = 0.01). Kaplan-Meier plots showed that the recurrence-free survival rate was significantly lower when the surgical checklist was not used (log-rank test result P < 0.01). CONCLUSIONS This study shows the therapeutic benefits of surgical checklist in improving the quality of resection during transurethral resection and reducing the recurrence rate in patients with non-muscle-invasive bladder cancer.

Abstract
The proportion of Gleason pattern (GP) 4 prostate cancers at prostate biopsy has a clinically significant impact on risk stratification for patients with prostate cancer. In pathological diagnosis including GP 4, a biopsy Gleason score (GS) of 3+4 has a more favorable prognosis than a GS of 4+3 and 4+4. However, the discrepancy between biopsy and prostatectomy specimens is well known. The current study investigated the clinical parameters and biopsy specimens associated with pathological downgrading after prostatectomy in biopsies with a GS of 4+3 or 4+4 prostate cancer. A total of 302 patients with prostate cancer who underwent robot-assisted radical prostatectomy between August 2013 and May 2019 were retrospectively reviewed. A total of 103 patients had biopsies with GSs of 4+3 and GS 4+4 (unfavorable pathology). The proportion of patients who were downgraded from unfavorable disease to GS ≤3+4 (favorable pathology) in prostatectomy specimens was investigated. Logistic regression analysis was used to explore the association between clinical parameters and downgrading in prostatectomy specimens. A total of 43 patients (41.7%) were downgraded from biopsy GS to prostatectomy GS. The proportions of downgrade in biopsy GS 4+4 and 4+3 were 14.6 and 27.1%, respectively. The percentage of highest GS out of positive biopsy cores and the maximum percentage of cancer involvement within a positive core with the highest GS were lower in the downgrade group than in the no downgrade group (45 vs. 66.7%, P=0.025; 20 vs. 30%, P=0.048, respectively). When performing multivariate logistic regression analysis, the only significant predictor for downgrade was lower percentage of highest GS cores out of positive biopsy cores (odds ratio, 2.469; 95% confidence interval, 1.029-5.925 P=0.043). In conclusion, patients with biopsy GS 4+4 and 4+3 often exhibit a downgrade to GS 3+4 or less in prostatectomy specimens. The lower percentage of highest GS cores out of positive biopsy cores was associated with downgrade.

Abstract
OBJECTIVES To determine the square measure threshold of prostate cancer lesions in pathological specimens showing PI-RADS categories 3 to 5, and to identify the pathological characteristics of cancerous lesions over the threshold. METHODS Cancer foci detected in horizontal sections of specimens were defined as pathological cancerous lesions, in which square measure, lesion location (peripheral or transition zone), Gleason pattern (GP), GP4-5 component percentages, and GP 4 subtypes were assessed. A receiver operating characteristic curve was used to determine the threshold of the square measure of pathological specimens that distinguishes between lesions of PI-RADS categories 1 and 2 and those of 3 to 5. Univariable and multivariable analyses were performed to determine the histopathological features associated with PI-RADS categories 3 to 5. RESULTS A total of 100 consecutive patients underwent multiparametric magnetic resonance imaging before robotic-assisted laparoscopic prostatectomy. A total of 1366 pathological cancerous lesions were detected, 217 of which were classified as PI-RADS categories 3 to 5. A square measure of 40 mm2 on pathological specimens was the threshold for PI-RADS categories 3 to 5. Of the 415 lesions that were over 40 mm2, 211 lesions exhibited PI-RADS categories 1, 2 and 204 lesions exhibited PI-RADS categories 3 to 5. Multiple logistic regression analysis showed that square measure, fused glands, and cribriform glands were independently associated with PI-RADS categories 3 to 5. CONCLUSION Cancerous lesions over 40 mm2 showing PI-RADS categories 3 to 5 are associated with square measure, fused glands, and cribriform glands.

Abstract
Abstract
Background
The prognosis, the underlying substrate and clinical outcomes of treatment are unclear in patients with cardiac sarcoidosis (CS)-related ventricular tachycardia (VT).
Objective
This study investigated the prognosis and the relationship between electroanatomical mapping (EAM) and imaging findings in patients with CS-related VT.
Methods
A total of 203 CS patients (Age 68.1±11.6 years, 87 males) were enrolled at two tertiary care medical centers between 2000 and 2018. All met the 2016 Japanese Circulation Society guidelines for diagnosis of CS. They were followed for a composite of major adverse cardiac events (MACE) including cardiac death, heart transplantation, unscheduled hospitalization for heart failure, and life-threatening ventricular arrhythmias. Distribution of late gadolinium enhancement (LGE) on cardiac MRI (CMR) and/or an abnormal myocardial 18F-fluorodeoxyglucose (FDG) uptake on positron emission tomography at diagnosis were examined. The relationship between EAM and the image findings were also analyzed in patients with radiofrequency ablation (RFA) for VT.
Results
During a median follow-up of 53 months, 87 of the 203 patients (43%) experienced a MACE. Baseline factors associated with MACE were presence of sustained VT (HR, 2.43, 95% CI 1.54–3.85, P<0.001), left ventricular ejection fraction below 50% (HR, 1.95 95% CI 1.07–3.56, P=0.029), and abnormal myocardial FDG uptake (HR, 2.42 95% CI 1.04–5.61, P=0.039). Overall, 69 of the 203 patients (34%) experienced sustained VT. Abnormal myocardial FDG uptake was significantly more prevalent in patients with VT than in those without (92.7% vs. 78.5%, P=0.02). A total of 25 patients (9.9%) required RFA for CS-related VT (Age 64.0±8.7 years, 12 males, 1.32±0.56 RFAs per patient). Abnormal electrocardiograms (EGM) were observed in 22 of the 25 patients (88%). LGE was more frequent than abnormal FDG uptake in areas with an abnormal EGM (77% vs. 41%; P=0.002). Over a mean follow-up period of 67-months, 13 of the 25 patients with RFA (52%) remained free of VT episodes (Figure). VT recurred in nine of the 12 patients with RFA and in 17 of the 47 patients without RFA, but was suppressed by intensive pharmacologic therapy such as the combined use of amiodarone and sotalol. In patients with CS-related VT, survival without experiencing a MACE did not differ in participants with or without RFA.
Conclusions
In our 203 CS patients, sustained VT and abnormal FDG uptake were associated with worse cardiac outcomes. The prevalence of abnormal FDG uptake was significantly higher in patients with CS-related VT, LGE on CMR was more frequent within localized areas of an abnormal EGM, suggesting that both scar itself and the associated inflammation were involved in the pathogenesis of CS-related VT. Successful RFA of CS-related VT is still challenging, and recurrence is common. Preprocedural CMR can be useful in detecting abnormal EGMs that are potential targets for substrate ablation.

Abstract
Abstract
Background
Sarcoidosis is a systemic non-caseating granulomatous disease of unknown etiology. Cardiac involvement (cardiac sarcoidosis, CS) has been reported to be an important prognostic factor in this disease because of heart failure and/or ventricular arrhythmia, and corticosteroid therapy is usually prescribed to prevent cardiac events. However, little is known about the relationship of cardiac function and concomitant corticosteroid therapy on later cardiac events in CS.
Objective
We evaluated the relationship between prognosis and left ventricular ejection fraction (LVEF) at the time of diagnosis in CS patients from the Japanese nationwide questionnaire survey.
Methods
Total of 757 Japanese patients from 57 hospitals who diagnosed CS were examined. Patients who unsatisfied the criteria of the Japanese new guidelines, or who underwent cardiac transplantations were excluded, and 420 patients (287 females, mean age 60±13 years old, median follow-up periods 1864 days [interquartile range: 845–3159 days]) were analyzed. The relationship of adverse events (all-cause death, cardiovascular death, and appropriate ICD [Implantable Cardioverter Defibrillator] discharge) and LVEF (with corticosteroid 84%) (low LVEF: LVEF≤35% n=98 [with corticosteroid in 78%], moderate LVEF: LVEF 35–50% n=104 [with corticosteroid in 93%], normal LVEF: 50≤LVEF n=218 [with corticosteroid in 83%]) were evaluated respectively.
Results
89 CS patients developed all-cause death (n=50), cardiovascular death (n=30) or appropriate ICD discharge (n=48). The frequency of corticosteroid therapy was not different in the each LVEF group, but Kaplan-Meier analysis revealed that all-cause death, cardiovascular death, and all cardiovascular adverse events were more observed in lower LVEF group (log-rank p<0.0001). Furthermore, multivariate Cox hazard analysis revealed that LVEF was a most important independent prognostic factor in CS.
Conclusion
This Japanese nationwide questionnaire survey data showed that initial LVEF was an independent and strong prognostic predictor in CS, therefore primary prevention would be needed even after starting corticosteroid in patients with decreased cardiac function.

Abstract
Abstract
Background
Sarcoidosis is a systemic inflammatory syndrome of unknown etiology and cardiac involvement has been reported to be an important prognostic factor in this disease. An autopsy study has reported that the frequency of this cardiac involvement (cardiac sarcoidosis: CS) varies in the different countries and races and very frequent in Japanese patients. We therefore performed the nationwide questionnaire survey and try to clarify the clinical characteristics and corticosteroid effect in CS, especially focused on arrhythmic events in this disease.
Methods
Total of 757 Japanese patients from 57 hospitals who diagnosed CS were examined. Patients who unsatisfied the criteria of the Japanese new guidelines, or who underwent cardiac transplantations were excluded, and 420 patients (287 females, median follow-up periods 1864 days [interquartile range: 845–3159 days]) were analyzed. The clinical outcome and corticosteroid effect were evaluated.
Results
Clinical characteristics at diagnosis was as follows: female dominant (68%), mean age of 60±13 years old, mean left ventricular ejection fraction was 49±16%. Arrhythmic events were very frequently observed as an initial cardiac manifestation in 263 patients (62%) of CS, of which atrioventricular block (AVB) in 174 (41%), ventricular tachycardia (VT) in 73 (17%) and AVB with VT in 17 (4%) (Figure 1A). Pacemaker was implanted in 166 patients (40%) and defibrillators was 137 patients (33%). Corticosteroid was prescribed in 144 (83%) of 174 patients with AVB and in 62 (85%) of 73 patients with VT. Initial dose was mean 47.9 mg and maintenance dose of mean 7.3 mg. Corticosteroid improved VT as good as AVB (27% vs. 29%). However, corticosteroid sometimes worsened VT events compared with AVB (10% vs. 2%) (Figure 1B). During the course of follow-up, 32 patients were needed to increase corticosteroid in 23 of AVB and 10 of VT cases. However, there were no difference in mortality between the groups, whether or not to increase corticosteroid. All survival rate was 92% (5-year mortality), 83% (10-year mortality) and free from all cause death and defibrillator charge was 81% (5 year), 71% (10 year).
Conclusion
Fatal arrhythmia is commonly observed in CS as a primary symptom. Corticosteroid sometimes worsen ventricular arrhythmia and appropriate defibrillator discharge was common. Thus, careful attention for activating ventricular arrhythmia would be needed during the follow-up period even after corticosteroid therapy.

Abstract
Abstract
Background
Prior ventricular tachycardia (VT) and low left ventricular ejection fraction (LVEF) are the most important prognostic factors in cardiac sarcoidosis (CS). Recently diagnosis of CS was renewed according to Japanese new guidelines. Patients with preserved cardiac function often have VT events, thus new guidelines recommends to assess the implantable cardioverter defibrillator (ICD) implantation for CS patients with preserved LVEF (35%≤LVEF<50%). However, the long-term prognosis of CS patients with preserved LVEF is unclear.
Objective
In CS patients with preserved LVEF, we evaluated the prognosis between VT manifestation and non-VT manifestation groups at CS diagnosis from Japanese nationwide questionnaire survey.
Methods
Total of 757 Japanese patients from 57 hospitals who diagnosed CS were examined. Patients who unsatisfied the criteria of the Japanese new guidelines, who had LVEF≤35%, LVEF>50%, or who underwent cardiac transplantations were excluded. 104 patients with LVEF 35–50% (67 females, mean age 60±15 years old, median follow-up periods 2134 days [interquartile range: 758–2935 days]) were analyzed. The prognosis between VT manifestation and non-VT manifestation groups at CS diagnosis were evaluated.
Results
30 patients had VT manifestation at CS diagnosis and 24 patients (80%) received ICDs. 74 patients had no VT manifestation at CS diagnosis and 19 patients (44%) received ICDs during follow up period. All-cause mortality was not different between two groups (Figure). Appropriate ICD therapy of non-VT manifestation group was significantly lower compared with that of VT manifestation group (log-rank p=0.001), however considerable number (n=7, 15%) of non-VT manifestation group had appropriate ICD therapy event during follow-up period. Cox hazard analysis revealed that concomitant non-sustained VT (NSVT) with atrioventricular block (AVB) was a predictor of appropriate ICD therapy in non-VT manifestation group.
Conclusion
This nationwide survey showed that considerable number of CS patients with preserved LVEF had VT events, independent of VT manifestation. Concomitant NSVT with AVB was a predictor of VT events, and ICD implantation should be assessed.

Abstract
Abstract
Background
Catheter ablation of atrial fibrillation (AF) is associated with risks of silent cerebral events. However, the timing of intraprocedural micro-embolic events or differences between open-irrigated radiofrequency (RF) and cryoballoon (Cryo) ablation are unclear. Newly developed real-time carotid artery Doppler is a simple non-invasive method to detect micro-embolic signals (MESs) during ablation.
Objective
We investigated the timing of detecting MESs during RF and Cryo ablation of AF.
Methods
During the first pulmonary vein isolation (PVI) session of AF, MESs were monitored by real-time carotid artery Doppler monitoring throughout the procedure. The MES counts were collected and evaluated separately during the different steps of the procedure (Figure).
Results
Thirty-three AF patients (RF/Cryo: 22/11 cases, 9 females, 69.5±11.6 y.o) were included. PVI was successfully accomplished in all patients with no major complications. The MES count was significantly greater in the RF group than Cryo group (table). In both groups, left atrial (LA) access (interatrial puncture) and sheaths insertion to the LA generated a significant number of MESs (RF: 1690 of 9116 MESs [18.5% of the total MESs], Cryo: 793 of 2285 MESs [34.7%]). In the RF group, MESs were observed incessantly during PVI (Figure). The LA dwell time was significantly longer in the RF group than Cryo group (table). In the RF group, the MES count was significantly greater in the longer LA dwell time group (LA dwell time >130min) than the shorter group (464.2±179.7 vs 302.6±138.2: P=0.049). During the cryo-applications in the Cryo group, the MESs were greatest during the first cryoballoon application (625 of 2285 MESs [27.4%]).
Conclusions
There were more MESs during RF ablation than cryoablation. MESs were recorded during a variety of steps throughout the procedure. In the RF group, most of MESs were recorded incessantly during radiofrequency ablation and greater number of MESs were recorded in patients with longer LA dwell time. In the Cryo group, most of MESs occurred during phases with a high probability of gaseous emboli.

Abstract
Abstract
Background
“Age” is one of the major concerns and determinants of the indications for catheter ablation (CA) of atrial fibrillation (AF). There are little safety data on CA of AF according to the age. This study aimed to assess the safety of CA in elderly patients undergoing CA of AF.
Methods and results
We investigated the complication rate of CA of AF for the different age groups (<60 years, 60–65, 65–70, 70–75, 75–80, 80–85, and ≥85) by a nationwide database (Japanese Registry Of All cardiac and vascular Diseases [JROAD]-DPC). The JROAD-DPC included 73,296 patients (65±11 years, 52,883 men) who underwent CA of AF from 516 hospitals in Japan. Aged patients had more comorbidities and a significantly increased CHADS2 score and higher rate of female according to a higher age. The overall complication rate was 2.6% and in-hospital mortality was 0.05%. By comparing each age group, complications occurred more frequently in higher aged groups. A multivariate adjusted hazard ratio revealed an increased age was independently and significantly associated with the overall complications (odds ratio was 1.25, 1.35, 1.72, 1.86, 2.76 and 3.13 respectively; reference <60 years).
Conclusions

Abstract
OBJECTIVES To clarify the potential therapeutic benefit of a second transurethral resection for high-grade Ta bladder cancer. METHODS From January 2009 to August 2019, 521 patients with bladder tumors underwent initial transurethral resection procedures at Kagawa University Hospital. Patients diagnosed with high-grade Ta bladder cancer considered to have been resected completely were included in this study. Recurrence and progression rates were compared between patients who received a second transurethral resection and those who did not. RESULTS We identified 97 eligible patients, including 22 patients who received a second transurethral resection. In terms of clinical characteristics, the proportion of patients with bladder cancer and upper urinary tract tumor history was lower in the second transurethral resection group than in the no second transurethral resection group (P < 0.01 and P = 0.03, respectively). The histopathological findings of 22 transurethral resection procedures were no cancer in 13 (59.2%), Ta in six (27.2%) and carcinoma in situ in three patients (13.6%). After the second transurethral resection, one patient (4.6%) had recurrent high-grade T1 bladder cancer. The no second transurethral resection group showed a 44% recurrence rate (33 patients), including five patients (6.7%) with progression, and consequently, had a higher rate of recurrence than in the second transurethral resection group (P < 0.01). Multivariate analysis showed that no second transurethral resection was the independent predictive factor influencing recurrence (hazard ratio 8.662, P = 0.04). The Kaplan-Meier curve showed that a second transurethral resection significantly decreased the recurrence rate than that of patients without a second transurethral resection (P < 0.01). CONCLUSIONS A second transurethral resection can reduce the recurrence rate in high-grade Ta bladder cancer, showing a possible therapeutic benefit of this procedure.

Abstract
We experienced a case of retroperitoneal hematoma secondary to spontaneous lumbar artery rupture in a kidney transplant patient. A 48-year-old woman underwent kidney transplantation for end-stage renal disease. Fifteen days after transplantation, the patient presented with strong abdominal and back pain on the right side, and blood examination showed severe anemia. Contrast-enhanced computed tomography and emergent angiography was performed, which showed extravasation from the lumbar artery. Selective angiographic embolization of the lumbar artery was performed, and the patient received a transfusion of red blood cells, following which, hemoglobin increased to 7.6 g/dl. Renal function then stabilized, and anemia improved.

Abstract
BACKGROUND Chronic inflammation is thought to be a major causative factor for the development of benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS). Tadalafil, a phosphodiesterase type 5 inhibitor (PDE5-I), which has been used for the treatment of BPH-LUTS in daily practice, is known to act at several urinary organs. In this study, focused on the prostate, we examined the effect of tadalafil on the pathological changes and inflammatory factors in a rat nonbacterial prostatitis (NBP) model. METHODS Forty ten-month-old male Wistar rats were divided into nonbacterial prostatitis (NBP), NBP with tadalafil treatment (NBP-tadalafil), control, and control treated with tadalafil (control-tadalafil) groups (n = 10 per group). The NBP and NBP-tadalafil groups were castrated and then received daily subcutaneous 17β-estradiol for 30 days. The control-tadalafil and NBP-tadalafil groups were administered daily oral tadalafil for 30 days. All rats were then sacrificed and pathological changes and inflammatory factors were assessed in the prostatic tissues. RESULTS In the NBP group, the stroma-to-epithelium (S/E) ratio in the ventral prostate was significantly higher than in the control group (P < 0.001). In the NBP-tadalafil group, the S/E ratio was significantly lower than in the NBP group (P < 0.001). The macrophage levels and the extent of T-cell infiltration in the NBP-tadalafil group were significantly lower than in the NBP group (P < 0.005; P < 0.001, respectively). Compared with the NBP group, tissue concentrations of inflammatory cytokines, such as tumor necrosis factor-α, interleukin-8, and interleukin-1β, were significantly downregulated in the NBP-tadalafil group (P < 0.01; P < 0.05; P < 0.005, respectively). CONCLUSIONS Tadalafil suppressed stromal predominance and showed anti-inflammatory effects in a rat NBP model in association with downregulation of inflammatory cytokines.

Abstract
BACKGROUND New-onset diabetes after kidney transplantation (NODAT) adversely affects patient survival. Excessive fat accumulation is generally considered a risk factor of NODAT. Body mass index (BMI) and abdominal circumference (AC) are frequently used to assess fat accumulation but cannot directly measure it. This study measured body fat area (BFA) via computed tomography and aimed to clarify whether preoperative BFA can predict the development of NODAT more accurately than BMI and AC. METHODS This retrospective study included 62 patients without diabetes mellitus who received living-donor kidney transplantation at our institute between July 2005 and April 2016. We investigated the association between preoperative BMI, AC, and BFA and the development of NODAT. RESULTS Eight patients (12.9%) developed NODAT during a mean follow-up period of 78.1 months. The preoperative BMI, AC, and BFA were markedly higher in NODAT patients than in patients without NODAT (P = .05, P = .02, P < .01, respectively). Correlation analyses revealed that BFA had a strong relationship with BMI (r = 0.68, P < .01) and AC (r = 0.77, P < .01). Receiver operating characteristic curve analyses demonstrated that BFA, compared to BMI and AC, had considerable predictive accuracy for the development of NODAT, with an area under the curve of 0.803 (sensitivity 75%, specificity 87%). CONCLUSIONS Preoperative BFA could be a predictive marker of NODAT in renal graft recipients. Our findings underline the importance of routine preoperative BFA measurements in clinical practice.

Abstract
Tumor necrosis factor (TNF) receptor-associated periodic syndrome (TRAPS) is an autoinflammatory disease that is caused by heterozygous mutations in the TNFRSF1A gene. Although more than 150 TNFRSF1A mutations have been reported to be associated with TRAPS phenotypes only a few, such as p.Thr79Met (T79M) and cysteine mutations, have been functionally analyzed. We identified two TRAPS patients in one family harboring a novel p.Gly87Val (G87V) mutation in addition to a p.Thr90Ile (T90I) mutation in TNFRSF1A. In this study, we examined the functional features of this novel G87V mutation. In-vitro analyses using mutant TNF receptor 1 (TNF-R1)-over-expressing cells demonstrated that this mutation alters the expression and function of TNF-R1 similar to that with the previously identified pathogenic T79M mutation. Specifically, cell surface expression of the mutant TNF-R1 in transfected cells was inhibited with both G87V and T79M mutations, whereas the T90I mutation did not affect this. Moreover, peripheral blood mononuclear cells (PBMCs) from TRAPS patients harboring the G87V and T90I mutations showed increased mitochondrial reactive oxygen species (ROS). Furthermore, the effect of various Toll-like receptor (TLR) ligands on inflammatory responses was explored, revealing that PBMCs from TRAPS patients are hyper-responsive to TLR-2 and TLR-4 ligands and that interleukin (IL)-8 and granulocyte-macrophage colony-stimulating factor (GM-CSF) are likely to be involved in the pathogenesis of TRAPS. These findings suggest that the newly identified G87V mutation is one of the causative mutations of TRAPS. Our findings based on unique TRAPS-associated mutations provide novel insight for clearer understanding of inflammatory responses, which would be basic findings of developing a new therapeutic and prophylactic approach to TRAPS.

Abstract
UNLABELLED Root amputation, immunosuppressive therapy, mandibular tooth extraction, pre-existing inflammation, and longer duration of treatment with bone-modifying agents were significantly associated with an increased risk of medication-related osteonecrosis of the jaw. Hopeless teeth should be extracted without drug holiday before the development of inflammation in cancer patients receiving high-dose bone-modifying agents. INTRODUCTION No studies have comprehensively analyzed the influence of pre-existing inflammation, surgical procedure-related factors such as primary wound closure, demographic factors, and drug holiday on the incidence of medication-related osteonecrosis of the jaw (MRONJ). The purpose of this study was to retrospectively investigate the relationships between these various factors and the development of MRONJ after tooth extraction in cancer patients receiving high-dose bone-modifying agents (BMAs) such as bisphosphonates or denosumab. METHODS Risk factors for MRONJ after tooth extraction were evaluated with univariate and multivariate analyses. The following parameters were investigated in all patients: demographics, type and duration of BMA use, whether BMA use was discontinued before tooth extraction (drug holiday), the duration of such discontinuation, the presence of pre-existing inflammation, and whether additional surgical procedures (e.g., incision, removal of bone edges, root amputation) were performed. RESULTS We found that root amputation (OR = 22.62), immunosuppressive therapy (OR = 16.61), extraction of mandibular teeth (OR = 12.14), extraction of teeth with pre-existing inflammation, and longer duration (≥ 8 months) of high-dose BMA (OR = 7.85) were all significantly associated with MRONJ. CONCLUSIONS Tooth extraction should not necessarily be postponed in cancer patients receiving high-dose BMA. The effectiveness of a short-term drug holiday was not confirmed, as drug holidays had no significant impact on MRONJ incidence. Tooth extraction may be acceptable during high-dose BMA therapy until 8 months after initiation.

Abstract
Post-transplant immunoglobulin A (IgA) nephropathy (IgAN) in the allograft is the major cause of allograft loss. Using a protocol biopsy, latent mesangial IgA deposition (IgAD) can be detected in the allograft. Latent IgAD is distinguished from IgAN by the absence of urinary abnormalities, although IgA is observed in the mesangium. However, the pathophysiology and most appropriate treatment strategy for latent mesangial IgAD in the allograft remain to be fully determined. Importantly, it is unknown whether all cases of post-transplant asymptomatic IgAD progress to symptomatic IgAN; indeed, IgA deposits disappear in some cases. The differences in allograft prognosis between asymptomatic IgAD and IgAN have also not been determined. Non-invasive methods of diagnosis of IgAD in the allograft using serological and pathological biomarkers are being developed. Possible serum biomarkers include serum galactose-deficient IgA1 (Gd-IgA1), Gd-IgA1-specific IgG and Gd-IgA1-specific IgA, and its immune complexes. Immunofluorescence analysis using Gd-IgA1 monoclonal antibody may provide a pathological biomarker. These serological and pathological biomarkers may be suitable for the characterization of the stage of IgAD. However, there is insufficient information regarding whether serological and pathological biomarkers can predict the progression of asymptomatic IgAD to symptomatic IgAN. We propose that the pathogenesis of IgAN can be defined through the clinical study of IgAD in the allograft using protocol biopsies conducted by nephrologists involved in clinical kidney transplantation.

Abstract
STUDY QUESTION Is actin capping protein (CP) β3 involved in human spermatogenesis and male infertility? SUMMARY ANSWER Human CPβ3 (hCPβ3) is expressed in testis, changes its localization dynamically during spermatogenesis, and has some association with male infertility. WHAT IS KNOWN ALREADY The testis-specific α subunit of CP (CPα3) was previously identified in human, and mutations in the cpα3 gene in mouse were shown to induce malformation of the sperm head and male infertility. However, CPβ3, which is considered to be a heterodimeric counterpart of CPα3, has been neither characterized in human nor reported in association with male infertility. STUDY DESIGN, SIZE, DURATION To confirm the existence of CPβ3 in human testis, fresh semen samples from proven fertile men were analyzed. To investigate protein expression during spermatogenesis, cryopreserved testis obtained from men with obstructive azoospermia were examined by immunofluorescent analysis. To assess the association of CP with male infertility, we compared protein expression of human CPα3 (hCPα3) and hCPβ3 using immunofluorescent analysis of cryopreserved sperm between men with normozoospermia (volunteers: Normo group, n = 20) and infertile men with oligozoospermia and/or asthenozoospermia (O + A group, n = 21). PARTICIPANTS/MATERIALS, SETTING, METHODS The tissue-specific expression of hCPβ3 was investigated by RT-PCR and Western blot analysis. To investigate whether hCPα3 and hCPβ3 form a heterodimer, a tandem expression vector containing hcpα3 tagged with monomeric red fluorescent protein 1 and hcpβ3 tagged with enhanced green fluorescent protein in a single plasmid was constructed and analyzed by co-immunoprecipitation (Co-IP) assay. The protein expression profiles of hCPα3 and hCPβ3 during spermatogenesis were examined by immunohistochemical analysis using human spermatogenic cells. The protein expressions of hCPα3 and hCPβ3 in sperm were compared between the Normo and O + A groups by immunohistochemical analysis. MAIN RESULTS AND THE ROLE OF CHANCE RT-PCR showed that mRNA of hcpβ3 was expressed exclusively in testis. Western blot analysis detected hCPβ3 with anti-bovine CPβ3 antibody. Co-IP assay with recombinant protein showed that hCPα3 and hCPβ3 form a protein complex. At each step during spermatogenesis, the cellular localization of hCPβ3 changed dynamically. In spermatogonia, hCPβ3 showed a slight signal in cytoplasm. hCPβ3 expression was conspicuous mainly from spermatocytes, and hCPβ3 localization dynamically migrated from cytoplasm to the acrosomal cap and acrosome. In mature spermatozoa, hCPβ3 accumulated in the postacrosomal region and less so at the midpiece of the tail. Double-staining analysis revealed that hCPα3 localization was identical to hCPβ3 at every step in the spermatogenic cells. Most spermatozoa from the Normo group were stained homogenously by both hCPα3 and hCPβ3. In contrast, significantly more spermatozoa in the O + A versus Normo group showed heterogeneous or lack of staining for either hCPα3 or hCPβ3 (abnormal staining) (P < 0.001). The percentage of abnormal staining was higher in the O + A group (52.4 ± 3.0%) than in the Normo group (31.2 ± 2.5%). Even by confining the observations to morphologically normal spermatozoa selected in accordance with David's criteria, the percentage of abnormal staining was still higher in the O + A group (39.9 ± 2.9%) versus the Normo group (22.5 ± 2.1%) (P < 0.001). hCPβ3 in conjunction with hCPα3 seemed to play an important role in spermatogenesis and may be associated with male infertility. LARGE SCALE DATA Not applicable. LIMITATIONS REASONS FOR CAUTION Owing to the difficulty of collecting fresh samples of human testis, we used cryopreserved samples from testicular sperm extraction. To examine the interaction of spermatogenic cells or localization in seminiferous tubules, fresh testis sample of healthy males are ideal. WIDER IMPLICATIONS OF THE FINDINGS The altered expression of hCPα3 and hCPβ3 may not only be a cause of male infertility but also a prognostic factor for the results of ART. They may be useful biomarkers to determine the fertilization ability of human sperm in ART.

Abstract
BACKGROUND It is uncertain whether kidneys from marginal donors are suitable for live kidney transplantation. In deceased donor kidneys, tubular cell senescence affects allograft function. However, the degree of cell senescence in a living donor kidney with marginal factors has not been reported. In this study, we assessed the association of tubular cell senescence with allograft and remnant kidney function by a prospective observational clinical study. METHODS Thirty-eight living donor kidney transplantations were analyzed prospectively. Tissue sections obtained from preimplantation kidney biopsies were immunostained for p16INK4a to indicate cell senescence. Various kidney biomarkers were analyzed in urine and blood samples. RESULTS Of the 38 donors, 21 had marginal factors. Severe tubular senescence was found in living donors with overlapping marginal criteria. Tubular senescence in living donor kidneys was significantly related to donor age and lower recipient kidney function at 1 year after transplantation independently of donor age (β = -0.281; p = 0.050) but did not affect remnant kidney function after donation. Pretransplantation donor pre-estimated glomerular filtration rate and hypertension did not show a significant area under the curve (AUC) for prediction of high tubular senescence. High plasma levels of soluble αKlotho were associated with a higher predictive value for low tubular cell senescence with an AUC of 0.78 (95% CI 0.62-0.93; p < 0.01). CONCLUSIONS The nuclear p16-staining rate in donated kidney tubules is a predictor for allograft kidney function but not donor remnant kidney function. Detection of tubular cell senescence may facilitate selection of appropriate living donor candidates.

Abstract
UNLABELLED Root amputation, extraction of a single tooth, bone loss or severe tooth mobility, and an unclosed wound were significantly associated with increased risk of developing medication-related osteonecrosis of the jaw (MRONJ). We recommend a minimally traumatic extraction technique, removal of any bone edges, and mucosal wound closure as standard procedures in patients receiving bisphosphonates. INTRODUCTION Osteonecrosis of the jaws can occur following tooth extraction in patients receiving bisphosphonate drugs. Various strategies for minimizing the risk of MRONJ have been advanced, but no studies have comprehensively analyzed the efficacy of factors such as primary wound closure, demographics, and drug holidays in reducing its incidence. The purpose of this study was to retrospectively investigate the relationships between these various risk factors after tooth extraction in patients receiving oral bisphosphonate therapy. METHODS Risk factors for MRONJ after tooth extraction were evaluated using univariate and multivariate analysis. All patients were investigated with regard to demographics; type and duration of oral bisphosphonate use; whether they underwent a discontinuation of oral bisphosphonates before tooth extraction (drug holiday), and the duration of such discontinuation; and whether any additional surgical procedures (e.g., incision, removal of bone edges, root amputation) were performed. RESULTS We found that root amputation (OR = 6.64), extraction of a single tooth (OR = 3.70), bone loss or severe tooth mobility (OR = 3.60), and an unclosed wound (OR = 2.51) were significantly associated with increased risk of developing MRONJ. CONCLUSIONS We recommend a minimally traumatic extraction technique, removal of any bone edges, and mucosal wound closure as standard procedures in patients receiving bisphosphonates. We find no evidence supporting the efficacy of a pre-extraction short-term drug holiday from oral bisphosphonates in reducing the risk of MRONJ.
