Abstract
BACKGROUND In 2020, the Committee of Clinical Practical Guideline for IgA Nephropathy (IgAN) revised the clinical practice guidelines. Herein, we conducted a questionnaire survey to assess the potential discrepancies between clinical practice guidelines and real-world practice in Japan. METHODS A web-based survey of members of the Japanese Society of Nephrology was conducted between November 15 and December 28, 2021. RESULTS A total of 217 members (internal physicians: 203, pediatricians: 14) responded to the questionnaire. Of these respondents, 94.0% answered that the clinical practice guidelines were referred to "always" or "often." Approximately 66.4% respondents answered that histological grade (H-Grade) derived from the "Clinical Guidelines for IgA nephropathy in Japan, 3rd version" and the "Oxford classification" were used for pathological classification. Moreover, 73.7% respondents answered that the risk grade (R-grade) derived from the "Clinical Guidelines for IgA nephropathy in Japan, 3rd version" was referred to for risk stratification. The prescription rate of renin-angiotensin system blockers increased based on urinary protein levels (> 1.0 g/day: 88.6%, 0.5-1.0 g/day: 71.0%, < 0.5 g/day: 25.0%). Similarly, the prescription rate of corticosteroids increased according to proteinuria levels (> 1.0 g/day: 77.8%, 0.5-1.0 g/day: 52.8%, < 0.5 g/day: 11.9%). The respondents emphasized on hematuria when using corticosteroids. In cases of hematuria, the indication rate for corticosteroids was higher than in those without hematuria, even if the urinary protein level was 1 g/gCr or less. Few severe infectious diseases or serious deterioration in glycemic control were reported during corticosteroid use. CONCLUSION Our questionnaire survey revealed real-world aspects of IgAN treatment in Japan.

Abstract
OBJECTIVES Lifestyle behaviours associated with the incidence of type 2 diabetes mellitus (T2DM) need further clarification using health insurance data. STUDY DESIGN This is a cohort study. METHODS In 2015, 193,246 participants aged 40-74 years attended the specific health checkups and were observed up to 2020 in Fukushima, Japan. Using the principal component analysis, we identified two patterns from ten lifestyle behaviour questions, namely, the "diet-smoking" pattern (including smoking, alcohol drinking, skipping breakfast, eating fast, late dinner, and snacking) and the "physical activity-sleep" pattern (including physical exercise, walking equivalent activity, walking fast, and sufficient sleep). Then, individual pattern scores were calculated; the higher the scores, the healthier the behaviours. RESULTS The accumulative incidence rate of T2DM was 630.5 in men and 391.9 in women per 100,000 person-years in an average of 4 years of follow-up. Adjusted for the demographic and cardiometabolic factors at the baseline, the hazard ratio (95% confidence interval) of the highest versus lowest quartile scores of the "diet-smoking" pattern for T2DM risk was 0.82 (0.72, 0.92; P for trend = 0.002) in men and 0.87 (0.76, 1·00; P for trend = 0.034) in women; that of the "physical activity-sleep" pattern was 0.92 (0.82, 1·04; P for trend = 0.0996) in men and 0.92 (0.80, 1·06; P for trend = 0.372) in women. The "physical activity-sleep" pattern showed a significant inverse association in non-overweight men. CONCLUSIONS Lifestyle behaviour associated with a healthy diet and lack of smoking may significantly lower the risk of T2DM in middle-aged Japanese adults.

Abstract
OBJECTIVES When primary treatment has been inadequate, nivolumab and axitinib are often used as a secondary treatments for patients with metastatic renal cell carcinoma (mRCC). However, there have been few reports comparing the efficacy and safety of these drugs. METHODS We retrospectively investigated 58 patients treated with nivolumab and 57 patients treated with axitinib as secondary treatment between April 2013 and December 2019. We then assessed the clinical efficacy and safety of the treatments in both groups. RESULTS The most common primary therapy was sunitinib (61.7%). Both nivolumab and axitinib groups showed no significant differences in terms of the objective response rate and disease control rate (p = 0.280 and p = 0.518, respectively). Importantly, progression-free survival (PFS) and overall survival (OS) seemed to be similar in patients treated with nivolumab and axitinib (p = 0.527 and p = 0.266, respectively), irrespective of the objective response to primary therapy. Furthermore, a Cox proportional hazards model showed that pretreatment Karnofsky Performance Status was significantly associated with PFS and OS. Although the incidence of adverse events was significantly higher in the patients treated with axitinib, there was no significant difference in time to treatment failure between the two groups. CONCLUSIONS Nivolumab and axitinib showed similar clinical benefits as secondary treatment in patients with mRCC; thus, they should be an option in sequential therapy following treatment with tyrosine kinase inhibitors (TKIs). Future studies and feasible therapeutic biomarkers would help predict the clinical response to TKIs or immune checkpoint inhibitors in patients with mRCC.

Abstract
BACKGROUND Urinary extracellular vesicles (uEVs) secreted from bladder cancer contain cancer-specific proteins that are potential diagnostic biomarkers. We identified and evaluated a uEV-based protein biomarker for bladder cancer diagnosis and analysed its functions. METHODS Biomarker candidates, selected by shotgun proteomics, were validated using targeted proteomics of uEVs obtained from 49 patients with and 48 individuals without bladder cancer, including patients with non-malignant haematuria. We developed an enzyme-linked immunosorbent assay (ELISA) for quantifying the uEV protein biomarker without ultracentrifugation and evaluated urine samples from 36 patients with and 36 patients without bladder cancer. RESULTS Thirteen membrane proteins were significantly upregulated in the uEVs from patients with bladder cancer in shotgun proteomics. Among them, eight proteins were validated by target proteomics, and Ephrin type-A receptor 2 (EphA2) was the only protein significantly upregulated in the uEVs of patients with bladder cancer, compared with that of patients with non-malignant haematuria. The EV-EphA2-CD9 ELISA demonstrated good diagnostic performance (sensitivity: 61.1%, specificity: 97.2%). We showed that EphA2 promotes proliferation, invasion and migration and EV-EphA2 promotes the invasion and migration of bladder cancer cells. CONCLUSIONS We established EV-EphA2-CD9 ELISA for uEV-EphA2 detection for the non-invasive early clinical diagnosis of bladder cancer.

Abstract
BackgroundSystemic sclerosis (SSc) is an autoimmune disease that is characterized by systemic vasculopathy and fibrosis. Pulmonary hypertension (PH), defined as elevated pulmonary arterial pressure (PAP), is one of the leading causes of death of SSc1. In recent years, various therapies have been developed to target each of the pathogenesis of SSc – autoimmunity, vasculopathy, and fibrosis. Accordingly, treatment strategies based on risk stratification for PH progression are aspired; however, prediction of changes in PAP in diverse patients with SSc has not been established2.ObjectivesTo visualize the patterns of PAP elevation in SSc and to identify the clinical characteristics of each trajectory, by applying latent trajectory modeling for PAP measured repeatedly by echocardiography.MethodsThis was a multicenter, retrospective cohort study conducted at four referral hospitals in Kyoto, Japan. Patients with SSc who visited the study site between April 2008 and March 2021 and had at least three echocardiographic measurements of systolic pulmonary arterial pressure (sPAP) were included in this study. Follow-up concluded in March 2021. A group-based trajectory model3 was applied to the change in sPAP over time, and individual patients were classified into distinct subgroups that followed similar trajectories. The number and shape of the trajectories were estimated based on adequacy, goodness of fit, parsimony, and interpretability of the model. Clinical plausibility was assessed by comparing PH-free survival, i.e., time to either PH or death, for each trajectory. Multinomial logistic regression analysis was performed for baseline clinical characteristics associated with trajectory assignment.ResultsA total of 236 patients with a total of 1097 sPAP measurements were included. We identified five trajectories following the quadratic function as “rapid progression (n=9, 3.8%)”, “early elevation (n=30, 12.7%)”, “mid elevation (n=54, 22.9%)”, “late elevation (n=24, 10.2%)”, and “low stable (n=119, 50.4%)”. Each trajectory, in this order, showed earlier elevation of sPAP and shorter PH-free survival (Figure 1). In the multinomial logistic regression (with the “low stable” as reference), cardiac involvement was associated with the “rapid progression” (adjusted odds ratio [OR] 28.9, 95% confidence interval [CI] 3.21–259.5), diffuse cutaneous SSc was associated with the “early elevation” (OR 4.08, 95% CI 1.27–13.1), anti-centromere antibody positive was associated with the “mid elevation” (OR 4.50, 95% CI 1.11–18.2), and older age of onset was associated with the above three trajectories.ConclusionThe pattern of changes in pulmonary artery pressure over time in SSc can be classified into five distinct trajectories. Each trajectory differed in baseline clinical characteristics and outcomes.References[1]Pokeerbux MR, et al.

Abstract
Background Osteosarcoma arising from the bladder is extremely rare, with only 38 cases reported to our knowledge. It is often detected owing to hematuria, and is treated by surgery (for example, total cystectomy), radiation therapy, and chemotherapy; however, the prognosis is extremely poor. Case presentation An 83-year-old Japanese man underwent cystoscopy for postoperative follow-up of urothelial carcinoma of the bladder, which revealed a 2-cm nodular tumor on the right wall. He had a history of abdominal aortic aneurysm and hypertension, and had been smoking 15 cigarettes per day for 45 years. Seven years previously, the patient underwent transurethral resection of bladder tumor for a 5-cm tumor on the right wall of the bladder. The histopathological diagnosis was urothelial carcinoma. No recurrence had been detected since then. Transurethral resection of bladder tumor was performed, and the histopathological diagnosis was cystosarcoma. Because of his advanced age, we decided that it would be difficult to perform total cystectomy. We therefore performed a second transurethral resection of bladder tumor and found no residual tumor. At 29 months after surgery, the patient remains alive without recurrence. Conclusion Bladder osteosarcoma has a poor prognosis. However, our case was detected early, and treatment with transurethral resection of bladder tumor alone resulted in long-term survival without recurrence.

Abstract
BACKGROUND/AIM Immune checkpoint inhibitors (ICIs) have demonstrated a survival benefit for patients with cancer. However, the clinical outcomes of subsequent tyrosine kinase inhibitors (TKIs) after ICI failure in patients with metastatic renal cell carcinoma (mRCC) remain unclear. PATIENTS AND METHODS We retrospectively examined 38 patients with mRCC who started TKIs immediately after nivolumab with (combination group) or without ipilimumab (nivolumab group) between September 2016 and July 2019. RESULTS Of the 38 patients, 16 and 11 achieved partial response and stable disease, respectively, resulting in a 42.1% objective response rate and 71.1% disease control rate. The median progression-free survival (PFS) from TKI initiation was 8.8 and 12.9 months in the nivolumab and combination groups, respectively. PFS and overall survival were significantly longer in patients with long-term responses to previous ICI treatment (p=0.0152 and p=0.0155, respectively). CONCLUSION TKIs demonstrate adequate anti-tumour activity after treatment with ICIs in real-world settings.

Abstract
Proteomic analysis of urinary extracellular vesicles (EVs) is a powerful approach to discover potential bladder cancer (BCa) biomarkers, however urine contains numerous EVs derived from the kidney and normal urothelial epithelium, which can obfuscate information related to BCa cell-derived EVs. In this study, we combined proteomic analysis of urinary EVs and tissue-exudative EVs (Te-EVs), which were isolated from culture medium of freshly resected viable BCa tissues. Urinary EVs were isolated from urine samples of 11 individuals (7 BCa patients and 4 healthy individuals), and Te-EVs were isolated from 7 BCa tissues. We performed tandem mass tag (TMT)-labeling liquid chromatography (LC-MS/MS) analysis for both urinary EVs and Te-EVs and identified 1960 proteins in urinary EVs and 1538 proteins in Te-EVs. Most of the proteins identified in Te-EVs were also present in urinary EVs (82.4%), with 55 of these proteins showing upregulated levels in the urine of BCa patients (fold change > 2.0; P < .1). Among them, we selected 22 membrane proteins as BCa biomarker candidates for validation using selected reaction monitoring/multiple reaction monitoring (SRM/MRM) analysis on urine samples from 70 individuals (40 BCa patients and 30 healthy individuals). Six urinary EV proteins (heat-shock protein 90, syndecan-1, myristoylated alanine-rich C-kinase substrate (MARCKS), MARCKS-related protein, tight junction protein ZO-2, and complement decay-accelerating factor) were quantified using SRM/MRM analysis and validated as significantly upregulated in BCa patients (P < .05). In conclusion, the novel strategy that combined proteomic analysis of urinary EVs and Te-EVs enabled selective detection of urinary BCa biomarkers.

Abstract
Background Extracellular vesicles (EVs) including exosomes are present in blood, urine, and saliva and contain proteins, microRNAs, and messenger RNAs. We investigated microRNAs in urinary EVs to discover new biomarkers of prostate cancer (PCa). Methods We isolated EVs from urine obtained following digital rectal examination (DRE) of 14 men with elevated levels of serum prostate-specific antigen (PSA) [negative biopsy (n=4) and PCa with Gleason scores of 6 (n=3), 7 (n=3), and 8-9 (n=4)]. MicroRNAs extracted from EVs were analyzed by microRNA microarray. Results MicroRNAs miR-30b-3p and miR-126-3p were identified as being overexpressed in urinary EVs of the PCa patients versus the biopsy-negative men, but no microRNAs were associated with the Gleason score. In the independent cohort as well, these two microRNAs were overexpressed in urinary EVs from the PCa patients versus the negative-biopsy men. Logistic regression analysis adjusted by age and PSA showed that these two microRNAs were significantly associated with the prediction of PCa in biopsy specimens. Sensitivity and specificity of miR-30b-3p and miR-126-3p for the prediction of PCa were 46.4% and 88.0% and 60.7% and 80.0%, respectively, which were better than those of serum PSA (53.5% and 64.0%, respectively). Conclusions MiR-30b-3p and miR-126-3p in urinary EVs could be potential biomarkers of PCa.

Abstract
Recent studies showed the clinical utility of next-generation sequencing of urinary cell-free DNA (cfDNA) from patients with urothelial bladder cancer (UBC). In this study, we aimed to develop urinary cfDNA analysis by droplet digital PCR (ddPCR) as a high-throughput and rapid assay for UBC detection and prognosis. We analyzed urinary cfDNA of 202 samples from 2 cohorts. Test cohort was designed for investigating clinical utility of urinary cfDNA, and was composed of 74 samples from patients with UBC, and 52 samples of benign hematuria patients. Validation cohort was designed for validation and assessment of clinical utility comparing urinary cfDNA with UroVysion (Abbott, Illinois, USA), and was composed of 40 samples from patients with UBC, and 36 prospectively collected samples from patients under surveillance after surgery for urothelial carcinoma. We performed ddPCR analysis of hotspot gene mutations (TERT promoter and FGFR3). In the test cohort, the sensitivity of urinary cfDNA diagnosis was 68.9% (51/74) and the specificity was 100% in patients with UBC. The sensitivity increased to 85.9% when used in conjunction with urine cytology. In addition, patients with high TERT C228T allele frequency (≥14%) had significantly worse prognosis in bladder tumor recurrence than patients with low TERT C228T allele frequency or negative TERT C228T (p = 0.0322). In the validation cohort, the sensitivity of urinary cfDNA was 57.5% (23/40) and the specificity was 100% in UBC patients. The sensitivity of the combination of urine cytology with our hotspot analysis (77.5%) was higher than that of urine cytology with UroVysion (68.9%). In the post-surgical surveillance group, patients positive for the TERT C228T mutation had significantly worse prognosis for bladder tumor recurrence than mutation negative patients (p < 0.001). In conclusion, ddPCR analysis of urinary cfDNA is a simple and promising assay for the clinical setting, surpassing UroVysion for detection and prognosis determination in UBC.

Abstract
Most upper tract urothelial carcinomas (UTUC) are muscle invasive at the time of diagnosis. Current standard methods for the diagnosis of UTUC are invasive. Urine cytology is the only non-invasive test for detecting UTUC, but its sensitivity is low. A novel non-invasive assay for UTUC detection would improve patient outcome. This study aimed to investigate the mutation of cell-free DNA (cfDNA) in urine supernatant to develop a reliable diagnostic biomarker for UTUC patients. We studied urinary cfDNA from 153 individuals, including 56 patients with localized UTUC, and carried out droplet digital PCR assay for TERT promoter and FGFR3 hotspot mutations. We could detect mutations of TERT C228T in 22/56 (39.3%), TERT C250T in 4/56 (7.1%), and FGFR3 S249C in 9/56 (16.1%) patients. FGFR3 mutation was detected only in ≤pT1 tumors (positive predictive value: 100.0%). In combination with cytology results, the sensitivity was 78.6%, and the specificity was 96.0%. Although these data need to be validated in a larger-scale cohort, mutation analysis of TERT promoter and FGFR3 in urinary cfDNA has the potential to be a non-invasive diagnostic marker and reliable factor for tumor staging.

Abstract
Reliable biomarkers for renal cell carcinoma (RCC) have yet to be determined. Circulating tumor DNA (ctDNA) is an emerging resource to detect and monitor molecular characteristics of various tumors. The present study aims to clarify the clinical utility of ctDNA for RCC. Fifty-three patients histologically diagnosed with clear cell RCC were enrolled. Targeted sequencing was carried out using plasma cell-free DNA (cfDNA) and tumor DNA. We applied droplet digital PCR (ddPCR) to validate detected mutations. cfDNA fragment size was also evaluated using a microfluidics-based platform and sequencing. Proportion of cfDNA fragments was defined as the ratio of small (50-166 bp) to large (167-250 bp) cfDNA fragments. Association of mutant allele frequency of ctDNA with clinical course was analyzed. Prognostic potential was evaluated using log-rank test. A total of 38 mutations across 16 (30%) patients were identified from cfDNA, including mutations in TP53 (n = 6) and VHL (n = 5), and median mutant allele frequency of ctDNA was 10%. We designed specific ddPCR probes for 11 mutations and detected the same mutations in both cfDNA and tumor DNA. Positive ctDNA was significantly associated with a higher proportion of cfDNA fragments (P = .033), indicating RCC patients with ctDNA had shorter fragment sizes of cfDNA. Interestingly, the changes of mutant allele frequency in ctDNA concurrently correlated with clinical course. Positive ctDNA and fragmentation of cfDNA were significantly associated with poor cancer-specific survival (P < .001, P = .011). In conclusion, our study shows the clinical utility of ctDNA status and cfDNA fragment size as biomarkers for prognosis and disease monitoring in RCC.

Abstract
Renal cell carcinoma (RCC) is the most common type of kidney cancer in adults, responsible for approximately 90‑95% of cases. We previously reported a novel method that enables direct extraction of extracellular vesicles (EVs) from surgically resected viable tissues, yielding what we term tissue‑exudative extracellular vesicles (Te‑EVs). Quantitative LC/MS analysis identified 3,871 proteins in Te‑EVs, among which leukocyte‑associated immunoglobulin‑like receptor 1 (LAIR1) was highly enriched in tumor Te‑EVs. In the present study, we found that LAIR1 was significantly upregulated in clinical specimens of human RCC tumor tissues compared to that noted in adjacent non‑cancerous renal tissues as determined by quantitative PCR analysis. LAIR1 overexpression resulted in accelerated cell proliferation and tumor growth in RCC cells. Moreover, knockdown of LAIR1 using siRNA significantly inhibited cell proliferation in RCC cells. Mechanistically, LAIR1 upregulated the phosphorylation status of Akt, which in turn increased cell proliferation in RCC cells. In clinical RCC specimens, RCC patients with high LAIR1 mRNA expression showed poor progression‑free survival compared to those with low LAIR1 expression. These findings indicate that LAIR1 promotes tumorigenesis in RCC.

Abstract
Signal transducer and activator of transcription 3 (STAT3) plays a prominent role in the growth and invasion of several types of solid tumors. In this study, to assess the expression status and prognostic significance of the STAT3 pathway in upper urinary tract urothelial carcinoma (UTUC), we immunohistochemically stained for STAT3 and STAT3 pathway proteins, sphingosine-1-phosphate receptor 1 (S1PR1) and interleukin-6 (IL-6), in a tissue microarray containing 99 UTUC specimens. There were no significant associations between STAT3, S1PR1, or IL-6 expression pattern and tumor grade or pT stage. However, the patients with high STAT3 tumor had a significantly higher risk of both disease progression (p = 0.009) and cancer-specific mortality (p = 0.009), but not with tumors expressing S1PR1 or IL-6. High STAT3 expression in the nucleus was also associated with a significantly higher risk of both disease progression (p = 0.003) and cancer-specific mortality (p = 0.034). Multivariate analysis revealed that high STAT3 expression in the nucleus was significantly associated with cancer-specific survival after adjustment for pathological stage, lymph node involvement, lymphovascular invasion, and tumor grade (HR = 2.136, 95% CI = 1.009–4.767, p = 0.047). Our findings indicated that STAT3 could be a cancer-promoting factor and potentially a significant prognostic factor in UTUC.

Abstract
Purpose: High-fat diet (HFD) could induce prostate cancer progression. The aim of this study is to identify mechanisms of HFD-induced prostate cancer progression, focusing on inflammation.Experimental Design: We administered HFD and celecoxib to autochthonous immunocompetent Pb-Cre+;Pten(fl/fl) model mice for prostate cancer. Tumor growth was evaluated by tumor weight and Ki67 stain, and local immune cells were assessed by flow cytometry at 22 weeks of age. Cytokines which correlated with tumor growth were identified, and the changes of tumor growth and local immune cells after inhibition of the cytokine signals were evaluated in the mice. IHC analyses using prostatectomy specimens of obese patients were performed.Results: HFD accelerated tumor growth and increased the myeloid-derived suppressor cells (MDSCs) fraction and M2/M1 macrophage ratio in the model mice. Celecoxib-suppressed tumor growth, and decreased both local MDSCs and M2/M1 macrophage ratio in HFD-fed mice. HFD-induced tumor growth was associated with IL6 secreted by prostatic macrophages, as were phosphorylated STAT3 (pSTAT3)-positive tumor cells. Anti-IL6 receptor antibody administration suppressed tumor growth, and decreased local MDSCs and pSTAT3-positive cell fractions in HFD-fed mice. The tumor-infiltrating CD11b-positive cell count was significantly higher in prostatectomy specimens of obese than those of nonobese patients with prostate cancer.Conclusions: HFD increased MDSCs and accelerated prostate cancer tumor growth via IL6/pSTAT3 signaling in the mice. This mechanism could exist in obese patients with prostate cancer. IL6-mediated inflammation could be a therapeutic target for prostate cancer. Clin Cancer Res; 24(17); 4309-18. ©2018 AACR.

Abstract
Background Reliable biomarkers for renal cell carcinoma (RCC) have yet to be found. Circulating cell-free DNA (cfDNA) is an emerging resource for the diagnosis and prognosis of various cancers. This study aims to identify novel blood biomarkers for RCC. Materials And Methods Plasma cfDNA was extracted from RCC patients (n = 92) and healthy controls (n = 41). Levels of cfDNA were determined using quantitative real-time PCR of ACTB as the target gene, and cfDNA fragment size was measured using a microfluidics-based platform. Diagnostic potential was assessed using receiver operating characteristic (ROC) and logistic regression analysis, and prognostic potential was evaluated using log-rank test. Results Median levels of cfDNA from RCC patients were significantly higher than those from healthy controls (3803 vs 2242 copies/ml, p < 0.001). Median fragment sizes of cfDNA in RCC patients were shorter than those in healthy controls (170 vs 171 bp, p = 0.052). To evaluate level of cfDNA as a diagnostic tool for RCC, ROC curve analysis revealed a sensitivity of 63.0% and a specificity of 78.1%. Multivariate analysis indicated that age, gender and the level of cfDNA were significantly associated with the presence of RCC (p < 0.001, p = 0.013, p < 0.001, respectively). Additionally, shorter cfDNA fragment size was negatively associated with progression-free survival (p = 0.006). Conclusions Our study demonstrates the diagnostic and prognostic potential of plasma cfDNA as a biomarker for RCC.

Abstract
Background Extracellular vesicles are lipid bilayer vesicles containing protein, messengerRNA and microRNA. Cancer cell-derived extracellular vesicles may be diagnostic and therapeutic targets. We extracted extracellular vesicles from urine of urothelial carcinoma patients and the control group to identify cancer-specific microRNAs in urinary extracellular vesicles as new biomarkers. Materials and methods microRNA from urinary extracellular vesicles extracted from 6 urothelial carcinoma patients and 3 healthy volunteers was analyzed. We verified candidate microRNAs in an independent cohort of 60 urinary extracellular vesicles samples. To normalize the microRNA expression level in extracellular vesicles, we examined the following in extracellular vesicles: protein concentration, CD9 intensity, amounts of whole miRNAs, RNA U6B small nuclear expression and the creatinine concentration of original urine correlating with the counts of extracted extracellular vesicles measured by the NanoSight™ system. RESULTS From the microarray results 5 microRNAs overexpressed in urinary extracellular vesicles of urothelial carcinoma patients were identified. Creatinine concentration of original urine correlated most with particle counts of extracellular vesicles, indicating that creatinine could be a new tool for normalizing microRNA expression. MiR-21-5p was the most potent biomarker in urinary extracellular vesicles (sensitivity, 75.0%; specificity, 95.8%) and was also overexpressed in urinary extracellular vesicles from urothelial carcinoma patients with negative urine cytology. For the subgroup with negative urine cytology, the sensitivity was 75.0% and specificity was 95.8%. Conclusion MiR-21-5p in urinary extracellular vesicles could be a new biomarker of urothelial carcinoma, especially for urothelial carcinoma patients with negative urine cytology.

Abstract
Fucosylation is an important oligosaccharide modification associated with cancer and inflammation. We investigated whether urinary fucosylated PSA (Fuc-PSA) levels could be used for the detection of high Gleason score prostate cancer. Urine samples were collected from men with abnormal digital rectal examination findings or elevated serum PSA levels, before prostate biopsy. Lectin-antibody ELISA was used to quantify the Lewis-type or core-type fucosylated PSA (PSA-AAL) and core-type fucosylated PSA (PSA-PhoSL) in the urine samples. Both types of urinary Fuc-PSA were significantly decreased in the men with prostate cancer compared with the men whose biopsies were negative for cancer (P = 0.026 and P < 0.001, respectively). Both were also significantly associated with the Gleason scores of the biopsy specimens (P = 0.001 and P < 0.001, respectively). Multivariate analysis showed that PSA density, urinary PSA-AAL, and urinary PSA-PhoSL were independent predictors of high Gleason score prostate cancer. The area under the receiver-operator characteristic curve (AUC) value for the prediction of cancers of Gleason score ≥ 7 was 0.69 for urinary PSA-AAL and 0.72 for urinary PSA-PhoSL. In contrast, the AUC value was 0.59 for serum PSA, 0.63 for PSA density, and 0.58 for urinary PSA. In conclusion, a decreased urinary Fuc-PSA level is a potential marker for the detection of high Gleason score prostate cancer.

Abstract
There are no blood biomarkers for the diagnosis of renal cell carcinoma (RCC) in routine clinical use. We focused on the gene expression profile of peripheral blood cells obtained from RCC patients to discover novel biomarkers for RCC diagnosis. Using microarray analysis and quantitative verification, CXCL7 was shown to be significantly upregulated in the peripheral blood cells of RCC patients. Importantly, aberrant CXCL7 expression was confirmed even in peripheral blood cells obtained from early stage (pT1a) RCC patients, and the expression level of CXCL7 in peripheral blood cells was a potential independent biomarker for the diagnosis of RCC by receiver operating characteristic curve analysis (sensitivity, 70.0%; specificity, 64.0%; area under the curve = 0.722; multiple logistic regression analysis: odds ratio, 1.07; 95% confidence interval, 1.03-1.11; P = 0.0004). Moreover, CXCL7 expression in peripheral blood cells significantly decreased after resection of the primary tumor. CXCL7 is more highly expressed in PBMCs than in neutrophils from both healthy controls and RCC patients. Interestingly, CXCL7 expression in PBMCs from healthy volunteers was significantly elevated following coculture with RCC cells compared to those cocultured with normal cells as a control. These results suggest that aberrant CXCL7 expression in peripheral blood cells is induced by RCC cells and may serve as a novel biomarker in the diagnosis of RCC.

BACKGROUND Tumor-infiltrating macrophages, which are thought to be derived from blood monocytes, interact with tumor cells to promote cancer progression. The aim of this study was to assess the association of peripheral blood monocyte count with pathological findings and local tumor-infiltrating macrophages in prostatectomy specimens. METHODS Preoperative peripheral blood monocyte counts were retrospectively assessed for their associations with pathological findings (pathological T stage, Gleason Score, extraprostatic extension, seminal vesicle invasion, and surgical margin) and biochemical recurrence of 248 patients who underwent radical prostatectomy. Local tumor-infiltrating macrophages were also evaluated immunohistochemically for their association with peripheral monocyte counts. RESULTS The peripheral monocyte counts of the patients with extraprostatic extension, seminal vesicle invasion, or primary Gleason ≥4 were significantly higher than those of the patients without each of these pathological findings (P < 0.001, P = 0.034, and P = 0.004, respectively). Peripheral monocyte count was a significant predictor of adverse pathology and postoperative biochemical recurrence in localized prostate cancer by multivariate analysis (P = 0.001 and P = 0.041, respectively). Both the density and the count of tumor-infiltrating macrophages correlated significantly with the peripheral blood monocyte count (Spearman rank correlation coefficients were 0.463 and 0.649, respectively, P < 0.001). CONCLUSIONS Peripheral blood monocyte count reflecting local tumor-infiltrating macrophages was a predictive factor for tumor progression and prognosis in patients with localized prostate cancer. Elucidating the mechanism of the interaction of peripheral monocytes with tumor-infiltrating macrophages is necessary.

Abstract
Abstract
Urine collected after prostate massage is a promising source of new biomarkers of prostate cancer, and was reported to contain extracellular vesicles (EVs) that are secreted from prostate cancer cells. EVs are microvesicles secreted from various cell types. EVs contain microRNAs, proteins, and mRNAs and play a role in intercellular communications via the mechanisms of exocytosis and endocytosis. We aimed to discover a new biomarker for high Gleason score (GS) prostate cancer (PCa) in urinary EVs via quantitative proteomics.
Material and methods: Urine samples after massage were collected from 18 patients before prostate needle biopsy. Six patients had negative biopsy outcomes, 6 had Gleason score 6 prostate cancer (GS6), and 6 had Gleason score 8 to 9 prostate cancer (GS8-9). Urinary EVs were isolated from urine with ultracentrifuge. Protein extracted from EVs were labeled with 4-plex iTRAQ and liquid chromatography tandem mass spectrometry (LC-MS/MS) was used for proteome analysis. The candidate proteins were quantitated in the independent set by selected reaction monitoring/multiple reaction monitoring analysis (SRM/MRM).
Results: Seven proteins increased in patients with PCa compared to those with negative biopsy (ratio > 2.0, p-value < 0.05). Thirteen proteins were chosen for further analysis and verified in 29 independent urine samples (negative [n = 11], PCa [n = 18]) using selected reaction monitoring/multiple reaction monitoring. Among these candidate markers, fatty acid binding protein 5 (FABP5) was higher in the cancer group than in the negative group (p-value = 0.009) and was significantly associated with GS (p-value for trend = 0.011).
Conclusions: We applied the proteomic analysis to discover biomarkers in EVs in urine collected after prostate massage. FABP5 in urinary EVs could be a potential biomarker of high GS prostate cancer. Additional large-scale studies are warranted to confirm this finding.

Extracellular vesicles (EVs) are microvesicles secreted from various cell types. We aimed to discover a new biomarker for high Gleason score (GS) prostate cancer (PCa) in urinary EVs via quantitative proteomics. EVs were isolated from urine after massage from 18 men (negative biopsy [n = 6], GS 6 PCa [n = 6], or GS 8–9 PCa [n = 6]). EV proteins were labeled with iTRAQ and analyzed by LC-MS/MS. We identified 4710 proteins and quantified 3528 proteins in the urinary EVs. Eleven proteins increased in patients with PCa compared to those with negative biopsy (ratio >1.5, p-value < 0.05). Eleven proteins were chosen for further analysis and verified in 29 independent urine samples (negative [n = 11], PCa [n = 18]) using selected reaction monitoring/multiple reaction monitoring. Among these candidate markers, fatty acid binding protein 5 (FABP5) was higher in the cancer group than in the negative group (p-value = 0.009) and was significantly associated with GS (p-value for trend = 0.011). Granulin, AMBP, CHMP4A, and CHMP4C were also higher in men with high GS prostate cancer (p-value < 0.05). FABP5 in urinary EVs could be a potential biomarker of high GS PCa.

Abstract
Radiometric surveys have been conducted in support of a project investigating the potential of biofuel power generation coupled with remediation of forests contaminated with radionuclides following the Fukushima Daiichi accident. Surveys conducted in 2013 and 2014 were used to determine the distribution and time dependence of radionuclides in a cedar plantation and adjacent deciduous forestry subject to downslope radionuclide migration, and a test area where litter removal was conducted. The radiocaesium results confirmed enhanced deposition levels in the evergreen areas compared with adjacent areas of deciduous forestry, implying significant differences in depositional processes during the initial interception period in 2011. Surveys were conducted both with and without a collimator on both occasions, which modified the angular response of the detector to separate radiation signals from above and below the detector. The combined data have been used to define the influence of radionuclides in the forest canopy on dose rate at 1 m, indicating that, in evergreen areas, the activity retained within the canopy even by 2013 contributed less than 5% of ground level dose rate. The time dependent changes observed allow the effect of remediation by litter removal in reducing radionuclide inventories and dose rates to be appraised relative natural redistribution processes on adjacent control areas. A 15 × 45 m area of cedar forest was remediated in September 2013. The work involved five people in a total of 160 person hours. It incurred a total dose of 40-50 μSv, and generated 2.1 t of waste comprising forest litter and understory. Average dose rates were reduced from 0.31 μSv h-1 to 0.22 μSv h-1, with nuclide specific analyses indicating removal of 30 ± 3% of the local radiocaesium inventory. This compares with annual removal rates of 10-15% where radionuclide migration down-slope over ranges of 10-50 m could be observed within adjacent areas. Local increases were also observed in areas identified as sinks. The results confirm the utility of time-series, collimated, radiometric survey methods to account for the distribution and changes in radionuclide inventory within contaminated forests. The data on litter removal imply that significant activity transfer from canopy to soil had taken place, and provide benchmark results against which such remediation actions can be appraised.

Abstract
Five patients with unilateral leg lymph edema had intraarterial injections of lymphocytes in the affected leg with consequent improvement in 3. To assess the degree of lymph edema, T2 and intensity ratio between the 2 legs in STIR images were used. Mean and SD of T2 values in the subcutaneous tissue were measured using a triple echo sequence and found larger on the edematous side than in the opposite extremity. The mean T2 shortening obtained after the lymphocyte therapy correlated well with the reduction of limb circumference. Mean T2 reflects the fluid content, and SD of T2 the fluid distribution in the subcutaneous tissue. The degree of lymph edema and the effect of therapy can be evaluated quantitatively by measuring the value of the T2 relaxation time.

Abstract
OBJECTIVE Currently, polyurethane foam dressings are commercially available from many manufacturers. However, the pressure-reducing effect is expected to differ by the formulation and combination of the main and secondary ingredients and by manufacturing method. In this study, we investigated the effects of pressure reduction using dressing materials with various structural characteristics, including polyurethane foam dressings based on the engineering point of view, focusing on the dry state. METHOD Pressure was measured in a model that simulated compression on the sacral region in a decubitus position. Pressure was measured for different dressings: ten products, consisting of five types of material (polyurethane foam, hydropolymeric, Hydrofiber, hydrocolloid, and low-adherent absorbent). RESULTS All dressings used in this study showed significantly reduced pressure. ALLEVYN Non-Adhesive had the lowest pressure at 35.833 ± 1.155 mmHg, and DuoDERM Extra Thin CGF had the highest pressure at 66.867 ± 1.060 mmHg. The pressure of the control was 74.667 ± 1.405 mmHg. The other dressings were: ALLEVYN Adhesive: 44.233 ± 0.777 mmHg; ALLEVYN Gentle Border: 46.967 ± 1.537mmHg; Mepilex Border: 53.867 ± 0.231 mmHg; Biatain Silicone: 56.000 ± 0.520 mmHg; TIELLE: 57.267 ± 3.403 mmHg;Versiva XC: 65.900 ± 0.800 mmHg; DuoDERM CGF: 57.267 ± 1.007 mmHg; and Melolin: 53.433 ± 1.973 mmHg. CONCLUSION The pressure-reducing effect of dressing differs not only by material type but also by product. That is, the pressure-reducing effect can differ even if the dressings are of the same material type, such as polyurethane foam. Our study investigated only the effect of materials and structural characteristics on the cushion of dressings in the dry state. Therefore, further investigation is needed to confirm the effect of pressure reduction by dressing to meet the conditions in the clinic.

Abstract
A 96-year-old woman was diagnosed with colitis in our hospital. Her past history was breast cancer and lung cancer but no diabetes mellitus. She suddenly complained of lower abdominal pain. Abdominal computed tomography (CT) revealed intramural gas in the bladder wall and multiple poor contrasting area in her right kidney, which suggested emphysematous cystitis and acute focal bacterial nephritis. Indwelling urethral catheter was performed for bladder drainage and the treatment with antibiotics started. Urine culture revealed Klebsiella pneumoniae and blood culture was negative. After 3 weeks, the abdominal CT confirmed the decrease of gas within the bladder wall and improvement of contrasting area in the right kidney.

Abstract
OBJECTIVES To investigate the effects of IL-17 on IL-6, IL-1β, and matrix metalloproteinase (MMP-1) production, and to compare the MMP-1 production between the individual and combined effects of IL-1β and IL-6 in human periodontal ligament fibroblasts (HPDLF). MATERIALS AND METHODS Human periodontal ligament fibroblasts were cultured with IL-17 for 0.5, 1, 4, 24, 48, and 72 h, and were cultured with IL-1β, IL-6/sIL-6R, or a combination of IL-1β and IL-6/sIL-6R for 24 h. To measure the mRNA levels of IL-6, IL-1β, and MMP-1, total RNA was extracted from the cultured HPDLF, and a real-time PCR analysis was performed. The protein levels of IL-6, IL-1β, and MMP-1 in supernatants were measured using enzyme-linked immunosorbent assays (ELISAs). RESULTS IL-17 significantly increased the expression of IL-6 and MMP-1 mRNA and protein, while IL-17 transiently increased the expression of IL-1β mRNA. The combination of IL-1β and IL-6/sIL-6R induced significantly higher levels of MMP-1 protein than IL-1β alone. CONCLUSIONS IL-17 upregulated the production of IL-6 and MMP-1 sequentially in HPDLF. IL-6/sIL-6R may enhance the effects of IL-1β on MMP-1 production. The present results suggest that IL-17 induces MMP-1 production not only directly, but also indirectly by promoting IL-6 production, thus resulting in the degradation of collagens in the PDL.

Abstract
BACKGROUND/PURPOSE Facial skin must be linked to underlying structures to maintain facial morphology and prevent sagging, but the mechanism of facial skin retention is largely unknown. We aimed to elucidate this mechanism. METHODS Twenty-two cheek skin specimens (age range: 10s-60s, both genders) were observed histologically. And 30 cheek of healthy Japanese volunteers (age range: 30s-50s, female) was photographed and the severity of sagging was graded. Dermal layer morphology was observed non-invasively with ultrasound. Skin-retaining force was measured with a Cutometer MPA 580(®) , and sagging severity was evaluated by grading criteria. RESULTS Histological observation revealed characteristic convex structures at the bottom of the dermal layer. Non-invasive study showed that the depth of the convex structures, measured by ultrasonography, was significantly negatively related to the ratio of viscoelastic to elastic distention (Uv/Ue) and positively related to the ratio of elastic recovery to total deformation (Ur/Uf) at the cheek of female volunteers, measured by cutometer. It was also negatively related to sagging severity. Further, Ur/Uf was negatively and Uv/Ue was positively related to sagging severity.

Abstract
A 42-year-old woman was referred to our hospital with a chief complaint of asymptomatic gross hematuria. Computed tomography revealed a 4-cm tumour in the left kidney and radical nephrectomy was performed. Microscopically, the tumour was completely necrotic and consisted of nests of cells with abundant cytoplasm and large nuclei. Immunohistochemical analysis indicated complete infarction of the chromophobe renal cell carcinoma. Two years after surgery, the patient remained recurrence-free.

Abstract
We synthesized a new class of membrane-binding amphiphilic DNA consisting of hydrophilic phosphodiester-linked DNA and hydrophobic octyl phosphotriester-linked DNA. The amphiphilic DNA binds to the lipid membrane by inserting the hydrophobic region, which is facilitated by the presence of the complementary DNA strand.

Abstract
UNLABELLED The stem cell compartment in the esophageal epithelium is possibly located in the basal layer. We have identified significant expression of Smad2/3, phosphorylated at specific linker threonine residues (pSmad2/3L-Thr), in the epithelial cells of murine stomach and intestine, and have suggested that these cells are epithelial stem cells. In this study, we explore whether pSmad2/3L-Thr could serve as a biomarker for esophageal stem cells. We examined esophageal tissues from normal C57BL/6 mice and those with esophagitis. Double immunofluorescent staining of pSmad2/3L-Thr with Ki67, CDK4, p63, or CK14 was performed. After immunofluorescent staining, we stained the same sections with hematoxylin-eosin and observed these cells under a light microscope. We used the 5-bromo-2-deoxyuridine (BrdU) labeling assay to examine label retention of pSmad2/3L-Thr immunostaining-positive cells. We collected specimens 5, 10, 15 and 20 days after repeated BrdU administrations and observed double immunofluorescent staining of pSmad2/3L-Thr with BrdU. In the esophagus, pSmad2/3L-Thr immunostaining-positive cells were detected in the basal layer. These cells were detected between Ki67 immunostaining-positive cells, but they were not co-localized with Ki67. pSmad2/3L-Thr immunostaining-positive cells showed co-localization with CDK4, p63, and CK14. Under a light microscope, pSmad2/3L-Thr immunostaining-positive cells indicated undifferentiated morphological features. Until 20 days follow-up period, pSmad2/3L-Thr immunostaining-positive cells were co-localized with BrdU. pSmad2/3L-Thr immunostaining-positive cells significantly increased in the regeneration phase of esophagitis mucosae, as compared with control mice (esophagitis vs. CONTROL 6.889 ± 0.676/cm vs. 4.293 ± 0.659/cm; P < 0.001). We have identified significant expression of pSmad2/3L-Thr in the specific epithelial cells of murine esophagi. We suggest that these cells are slow-cycling epithelial stem-like cells before re-entry to the cell cycle.

Abstract
We report a case of solitary neurofibroma of the spermatic cord. A 48-year-old man was referred to our hospital with a complaint of a left inguinal mass. Magnetic resonance imaging (MRI) demonstrated a solid mass in the left inguinal region. The tumor was removed. Histopathological diagnosis was neurofibloma. He had no other findings of Von Recklinghausen disease. Only a few cases of solitary neurofibromas of spermatic cord have been reported.

Abstract
Transforming growth factor (TGF)-β, type I receptor (TβRI) and c-Jun N-terminal kinases (JNK) phosphorylate Smad3 differentially to create 2 isoforms phosphorylated (p) at the COOH-terminus (C) or at the linker region (L) and regulate hepatocytic fibrocarcinogenesis. This study aimed to compare the differences between how hepatitis B virus (HBV) infection affected hepatocytic Smad3 phosphorylated isoforms before and after anti-viral therapy. To clarify the relationship between Smad3 phosphorylation and liver disease progression, we studied 10 random patients in each stage of HBV-related fibrotic liver disease (F1-4) and also 10 patients with HBV-associated HCC. To examine changes in phosphorylated Smad3 signalling before and after anti-HBV therapies, we chose 27 patients with chronic hepatitis B who underwent baseline and follow-up biopsies at 52 weeks from the start of nucleoside analogue treatments (Lamivudine 100 mg daily or Telbivudine 600 mg daily). Fibrosis stage, inflammatory activity and phosphorylated Smad3 positivity in the paired biopsy samples were compared. Hepatocytic pSmad3C signalling shifted to fibrocarcinogenic pSmad3L signalling as the livers progressed from chronic hepatitis B infection to HCC. After nucleoside analogue treatment, serum alanine aminotransferase (ALT) and HBV-DNA levels in 27 patients with HBV-related chronic liver diseases were decreased dramatically. Decrease in HBV-DNA restored pSmad3C signalling in hepatocytes, while eliminating prior fibrocarcinogenic pSmad3L signalling. Oral nucleoside analogue therapies can suppress fibrosis and reduce HCC incidence by successfully reversing phosphorylated Smad3 signalling; even liver disease progressed to cirrhosis in chronic hepatitis B patients.

Abstract
A 66-year-old man presented with a retroperitoneal mass found in a routine medical examination. He had no complaints and no medical history. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a cystic mass in the retroperitoneal space, attached to the left crus of the diaphragm, 5.5 cm in size. Retroperitoneal cystic tumor was diagnosed, and transperitoneal tumor resection was performed. Pathological findings revealed a cyst wall lined with ciliated epithelium and cartilage, diagnosed as a retroperitoneal bronchogenic cyst. The patient was in good health at 12 months after the surgery with no evidence of recurrence.

Abstract
A 53-year-old man was diagnosed with bladder cancer with pelvic and para-aortic lymph node metastases. The clinical stage was cT3bN2M1. He underwent radical cystectomy and ileal conduit construction and retroperitoneal lymph node dissection after showing a partial response to 4 cycles of chemotherapy with methotrexate,vinblastine,doxorubicin and cisplatin (MVAC). Pathology showed prostatic invasion and para-caval lymph node metastasis. Pathological stage was pT4N0M1. After 3 cycles of MVAC therapy as adjuvant chemotherapy,new lymph node metastasis was revealed. He showed a complete response after 4 cycles of chemotherapy with gemcitabine and cisplatin (GC). He received 6 additional cycles of GC chemotherapy. Follow-up computed tomographic scan 3 months after the last chemotherapy showed portal vein thrombosis. He was treated with anticoagulant therapy,which dissolved the thrombus.

Abstract
A 67-year-old man visited an urological clinic with a chief complaint of urination pain. Cystourethroscopy and magnetic resonance imaging (MRI) examination revealed a bladder tumor (cT3bN0M0). Marked leukocytosis and respiratory distress with pleural effusion appeared. Pulse steroid therapy improved the general condition partially. The patient was sent to our hospital for further examination. Serum granulocyte colony-stimulating factor (G-CSF) and interleukin-6 (IL-6) were high and the pathological findings of bladder tumor obtained by transurethral resection (TUR) revealed an urothelial carcinoma that produced G-CSF and IL-6. Neoadjuvant systemic chemotherapy was performed along with use of steroid and sivelestat, which ameliorated the respiratory distress. After three courses of systemic chemotherapy, serum G-CSF and IL-6 normalized and cystoprostatectomy was performed. The patient has been in good health at 20 months after the surgery with no evidence of recurrence.
