Background: This study aims to investigate the factors contributing to the discrepancy in between biopsy Gleason score and radical prostatectomy Gleason score in patients diagnosed with prostate cancer. Methods: A total of 341 patients who underwent radical prostatectomy from 2011/04 to 2020/12 were identified. We only include patients with initial Gleason score of 6 after biopsy and enrolled 102 patients. Preoperative clinical variables and pathological variables were assessed to clarify the association with post-surgical Gleason score upgrading. The optimal cut-off points for significant continuous variables were then identified by obtaining the area under the receiver operating characteristic curve. Results: Upgrading was observed in 63 patients and non-upgrading in 39 patients. In the multiple variables assessed, smaller prostate volume (PV) (p value=0.0007), prostate specific antigen density (PSAD) (p value=0.0055), positive surgical margins (p value=0.0062) and pathological perineural invasion (p value=0.0038) were significant predictors of Gleason score upgrading. To further explore preclinical variables, a cut-off value for PV (38ml, p value=0.0017) and PSAD(0.26ng/ml2, p value=0.0013) were identified to be associated with Gleason score upgrading Conclusions: Smaller PV and elevated PSAD are associated with increased risk of Gleason score upgrading. The inverse relationship between PV and Gleason score upgrading might reflect the low androgenicity response of the prostate stroma.

Heart failure is one of the most common but complicated end-stage syndromes in clinical practice. Dilated cardiomyopathy is a myocardial structural abnormality that is associated with heart failure. Dual-specificity phosphatases (DUSPs) are a group of protein phosphatases that regulate signaling pathways in numerous diseases; however, their physiological and pathological impact on cardiovascular disease remains unknown. In the present study, we generated two transgenic mouse models, a DUSP7 knockout and a cardiac-specific DUSP7 overexpressor. Mice overexpressing DUSP7 showed an exacerbated disease phenotype, including severe dilated cardiomyopathy, heart failure, and cardiac death. We further demonstrated that high levels of DUSP7 inhibited ERK1/2 phosphorylation and influenced downstream c-MYC, c-FOS, and c-JUN gene expression but did not affect upstream activators. Taken together, our study reveals a novel molecular mechanism for DUSP7 and provides a new therapeutic target and clinical path to alleviate dilated cardiomyopathy and improve cardiac function.

Ubiquitin-mediated protein degradation has been reported to be involved in regulating the activity of oncoproteins and tumor suppressors. Dysfunction or dysregulation of the ubiquitin-proteasome system may induce tumorigenesis. Deubiquitinase ubiquitin-specific protease 2a (USP2a) has been reported to regulate cell growth or death and is involved in the pathogenesis of various diseases, including cancers. However, the role of USP2a in upper tract urothelial carcinoma (UTUC) has not been investigated yet. The goal of this study was to evaluate the clinical significance of USP2a expression in UTUC.A total of 110 UTUC cases were included in this study. USP2a expression level was evaluated through immunohistochemistry staining, and the correlation of USP2a expression level with both clinical and pathologic variables was analyzed.High USP2a expression level was observed in 48 (43.6%) cancer specimens. USP2a expression level was significantly correlated with tumor stage (P=0.001), grade (P=0.033), and tumor recurrence (P=0.008). High USP2a expression level was correlated with poor disease-free survival (P=0.005) and cancer-specific survival (P0.001). In addition, high USP2a expression level was an independent predictor of poor disease-free survival (hazard ratio=2.31; P=0.007) and cancer-specific survival (hazard ratio=5.49; P=0.009).This study indicated that USP2a protein expression level may be a potential biomarker for predicting UTUC patient survival. Further prospective studies are needed to investigate the role of USP2a in UTUC progression.

Introduction: Dysregulation of metal ion homeostasis is associated with urothelial carcinogenesis. From a published urinary bladder urothelial carcinoma (UBUC) transcriptome, we identified metallothionein 2A (MT2A) as the most significantly upregulated gene implicated in cancer progression among metal ion binding-related genes. Therefore, we analyzed the association between MT2A expression and clinical significance in our well-characterized cohort of patients with upper tract urothelial carcinoma (UTUC) and UBUC. Methods: We retrospectively reviewed the clinicopathological characteristics of 295 and 340 patients with UBUC and UTUC, respectively. MT2A expression was assessed using real-time reverse transcriptase-polymerase chain reaction and immunohistochemistry. We further correlated MT2A expression with clinicopathological factors, disease-specific survival (DSS) and metastasis-free survival (MFS) using the Pearson’s χ2 test, Kaplan-Meier analysis, and multivariate Cox proportional hazards model. Results: High MT2A expression was significantly associated with aggressive pathological features including high tumor stage, lymph node metastasis, high tumor grade, vascular invasion, and perineural invasion. In the Kaplan-Meier analysis, high MT2A expression was significantly correlated with poor DSS (p < 0.0001) and MFS (p < 0.0001); in the multivariate analysis, it was an independent predictor of CSS (p < 0.001) and MFS (p = 0.001). Gene coexpression analysis demonstrated that MT2A overexpression promotes UC progression through complement activation. Conclusion: High MT2A expression correlated with aggressive UC features and was an independent predictor of cancer metastasis and patient survival, suggesting its role in risk stratification and decision-making in patients with UTUC and UBUC.

Purpose Laparoscopic radical nephroureterectomy (LNU) has gradually become the new standard treatment for localized upper tract urothelial cancer (UTUC). With more blunt dissection and tactile sensation, hand-assisted LNU might shorten the operative time compared with the pure laparoscopic approach. However, whether the use of the hand-assisted or the pure laparoscopic approach has an effect on oncological outcomes remains unclear. Methods We retrospectively identified 629 patients with non-metastatic UTUC who underwent hand-assisted (n = 515) or pure LNU (n = 114) at 9 hospitals in Taiwan between 2004 and 2019. Overall survival, cancer-specific survival, recurrence-free survival, and bladder recurrence-free survival were compared between these two groups using inverse-probability of treatment weighting (IPTW) derived from the propensity scores for baseline covariate adjustment. Results The median follow-up period was 32.9 and 28.7 months in the hand-assisted and the pure groups, respectively. IPTW-adjusted Cox proportional hazards models showed that the laparoscopic approach (pure vs. hand-assisted) was not significantly associated with all-cause mortality (HR 0.79, 95% CI 0.49-1.24, p = 0.304), cancer-specific mortality (HR 0.88, 95% CI 0.51-1.51, p = 0.634), or extra-vesical recurrence (HR 0.65, 95% CI 0.41-1.04, p = 0.071). However, the pure laparoscopic approach was significantly associated with lower intra-vescial recurrence (HR 0.64, 95% CI 0.43-0.96, p = 0.029) for patients who underwent LNU. Kaplan-Meier curves also revealed that the pure laparoscopic approach was associated with better bladder recurrence-free survival compared with the hand-assisted laparoscopic approach in both the original cohort and the IPTW-adjusted cohort (log-rank p = 0.042 and 0.027, respectively). Conclusions The performance of hand-assisted or pure LNU does not significantly affect the all-cause mortality, cancer-specific mortality, or extra-vesical recurrence for patients with non-metastatic UTUC. However, the hand-assisted laparoscopic approach could increase the risk of intra-vesical recurrence for patients who undergo LNU.

BACKGROUND: Several groups have proposed features to identify low-risk patients who may benefit from endoscopic kidney-sparing surgery in upper tract urothelial carcinoma (UTUC). OBJECTIVE: To evaluate standard risk stratification features, develop an optimal model to identify ≥pT2/N+ stage at radical nephroureterectomy (RNU), and compare it with the existing unvalidated models. DESIGN, SETTING, AND PARTICIPANTS: This was a collaborative retrospective study that included 1214 patients who underwent ureterorenoscopy with biopsy followed by RNU for nonmetastatic UTUC between 2000 and 2017. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We performed multiple imputation of chained equations for missing data and multivariable logistic regression analysis with a stepwise selection algorithm to create the optimal predictive model. The area under the curve and a decision curve analysis were used to compare the models. RESULTS AND LIMITATIONS: Overall, 659 (54.3%) and 555 (45.7%) patients had ≤pT1N0/Nx and ≥pT2/N+ disease, respectively. In the multivariable logistic regression analysis of our model, age (odds ratio [OR] 1.02, 95% confidence interval [CI] 1.0-1.03, p = 0.013), high-grade biopsy (OR 1.81, 95% CI 1.37-2.40, p

BACKGROUND: Citrin deficiency (CD) is an autosomal recessive disease resulting from biallelic mutations of the SLC25A13 gene. This study aimed to investigate the molecular epidemiological features of CD in the Guangdong and Shaanxi provinces of China. METHODS: A total of 3,409 peripheral blood samples from Guangdong and 2,746 such samples from Shaanxi province were collected. Four prevalent SLC25A13 mutations NG_012247.2 (NM_014251.3): c.852_855del, c.1638_1660dup, c.615+5G>A, and c.1751-5_1751-4ins(2684) were screened by using the conventional polymerase chain reaction (PCR)/PCR-restriction fragment length polymorphism and newly-developed multiplex PCR methods, respectively. The mutated SLC25A13 allele frequencies, carrier frequencies, and CD morbidity rates were calculated and then compared with the Chi-square and Fisher’s exact tests. RESULTS: The mutations were detected in 68 out of 6,818 SLC25A13 alleles in Guangdong and 29 out of 5,492 alleles in the Shaanxi population. The carrier frequencies were subsequently calculated to be 1/51 and 1/95, while the CD morbidity rates were 1/10,053 and 1/35,865, in the 2 populations, respectively. When compared with the Shaanxi population, Guangdong exhibited a higher frequency of mutated SLC25A13 allele (68/6,818 vs. 29/5,492, χ(2)=8.570, P=0.003) in general, with higher c.852_855del (54/6,818 vs. 13/5,492, χ(2)=17.328, P=0.000) but lower c.1751-5_1751 -4ins(2684) (2/6,818 vs. 9/5,492, P=0.015) allele frequencies. The distribution of c.615+5G>A and c.1638_1660dup between the 2 provinces, as well as all 4 prevalent mutations among different geographic regions within the 2 provinces, did not differed significantly. CONCLUSIONS: Our findings depicted the CD molecular epidemiological features in Guangdong and Shaanxi populations, providing preliminary but significant laboratory evidences for the subsequent CD diagnosis and management in the 2 provinces of mainland China.

Thickness reduction or loss of the calcareous eggshell is one of major phenotypic changes in the transition from oviparity to viviparity. Whether the reduction of eggshells in viviparous squamates is associated with specific gene losses is unknown. Taking advantage of a newly generated high-quality genome of the viviparous Chinese crocodile lizard (Shinisaurus crocodilurus), we found that ovocleidin-17 gene (OC-17), which encodes an eggshell matrix protein that is essential for calcium deposition in eggshells, is not intact in the crocodile lizard genome. Only OC-17 transcript fragments were found in the oviduct transcriptome, and no OC-17 peptides were identified in the eggshell proteome of crocodile lizards. In contrast, OC-17 was present in the eggshells of the oviparous Mongolia racerunner (Eremias argus). Although the loss of OC-17 is not common in viviparous species, viviparous squamates show fewer intact eggshell-specific proteins than oviparous squamates. Our study implies that functional loss of eggshell-matrix protein genes may be involved in the reduction of eggshells during the transition from oviparity to viviparity in the crocodile lizard.

The conformal coating or surface modification in high aspect ratio nanostructures is a tough challenge using traditional physical/chemical vapor deposition, especially for metal deposition. In this work, the growth behavior of iridium (Ir) metal formed by atomic layer deposition (ALD) in anodic aluminum oxide (AAO) templates was explored deeply. It is found that the surface hydrophilicity is crucial for the nucleation of ALD Ir. An

Microplastics as a prevalent pollutant in water bodies have recently attracted widespread attention. To investigate the spatial and temporal distribution characteristics of microplastics in freshwater rivers and their migration patterns, the surface water, sediments, and subsidence zone of the Xiangxi River, a tributary of the Yangtze River, were sampled and analyzed in November 2020 and April 2021, respectively. The results showed that the average abundance of microplastics in the surface water of Xiangxi River was (6.64±1.32) n·L

Upper tract urothelial carcinoma (UTUC) is a rare tumor with an incidence that varies greatly between Eastern and Western countries. Transaldolase 1 (TALDO1) is a rate-limiting enzyme of the pentose phosphate pathway. In humans, aberrant TALDO1 activity has been implicated in various autoimmune diseases and malignancies; however, the function of TALDO1 in UTUC has not been previously investigated. Here we evaluated the clinical significance of TALDO1 expression in 115 paraffin-embedded tumor samples from patients with UTUC using immunohistochemistry. Our results demonstrated that there was an association between high TALDO1 expression and advanced stage (P = 0.011), tumor size (P = 0.005), tumor location (P = 0.047), distant metastases (P = 0.023), local recurrence (P = 0.002), and cancer death (P = 0.003). Using univariate and multivariate analyses, we found that chemotherapy was an independent factor for bladder recurrence-free survival. Late stage (III/IV) and high TALDO1 expression were independent prognostic factors for progression-free and cancer-specific survival. In summary, increased TALDO1 expression in UTUC was significantly correlated with late stage, tumor size, tumor location, distant metastases, local recurrence, and cancer death. Therefore, high TALDO1 expression could be a predictor of poor survival in patients with UTUC. Further studies are necessary to investigate the role of TALDO1 in UTUC development.

The metabolic syndrome was associated with bladder cancer in the previous studies. However, there have no large-scale cohort studies to elucidate the relationship between metabolic syndromes and urothelial carcinoma including urinary bladder urothelial carcinoma (UBUC) and upper tract urothelial carcinoma (UTUC). We analyze a population-based cohort study by using physical examination data and diagnosis of UC from the Taiwan Cancer Registry Database. Differences in demographic and clinical characteristics among UTUC and non-UTUC groups, UBUC and non-UBUC groups were compared. Odds ratios (ORs) for determining risk factors were estimated through the multiple logistic regression model. A total of 557,063 records for 211,319 participants which consisted of 31 UTUC and 309 UBUC met the eligibility criteria in this study. Our results showed that female are more likely to develop UTUC than male. As opposed to UTUC, male are more likely to develop UBUC than female. It also showed that participants smoked or chewed betel quid daily are more likely to develop UBUC. Age and estimated glomerular filtration rate (eGFR) are significantly increased the risk of developing UTUC. The association between the eGFR and risk of UTUC is stronger (P

Purpose Inconsistent prognostic implications of body mass index (BMI) in upper tract urothelial carcinoma (UTUC) have been reported across different ethnicities. In this study, we aimed to analyze the oncologic role of BMI in Asian and Caucasian patients with UTUC. Methods We retrospectively collected data from 648 Asian Taiwanese and 213 Caucasian American patients who underwent radical nephroureterectomy for UTUC. We compared clinicopathologic features among groups categorized by different BMI. Kaplan-Meier method and Cox regression model were used to examine the impact of BMI on recurrence and survival by ethnicity. Results According to ethnicity-specific criteria, overweight and obesity were found in 151 (23.2%) and 215 (33.2%) Asians, and 79 (37.1%) and 78 (36.6%) Caucasians, respectively. No significant association between BMI and disease characteristics was detected in both ethnicities. On multivariate analysis, overweight and obese Asians had significantly lower recurrence than those with normal weight (HR 0.631, 95% CI 0.413-0.966; HR 0.695, 95% CI 0.493-0.981, respectively), and obesity was an independent prognostic factor for favorable cancer-specific and overall survival (HR 0.521, 95% CI 0.342-0.794; HR 0.545, 95% CI 0.386-0.769, respectively). There was no significant difference in outcomes among normal, overweight and obese Caucasians, but obese patients had a relatively poorer 5-year RFS, CSS, and OS rates of 52.8%, 60.5%, and 47.2%, compared to 54.9%, 69.1%, and 54.9% for normal weight patients. Conclusion Higher BMI was associated with improved outcomes in Asian patients with UTUC. Interethnic differences could influence preoperative counseling or prediction modeling in patients with UTUC.

Objective This paper aims to clarify the concept of occupational burnout (OB) as well as develop appropriate methods to relieve or prevent OB in the nursing profession. Methods Walker and Avant’s eight-step approach of concept analysis was applied. Results OB was defined as a chronic form of work-related stress. Accurately, it was characterized by emotional exhaustion, depersonalization/cynicism, and reduced personal accomplishment/inefficacy. Antecedents of burnout included (a) demographic characteristics; (b) chronic exposure to work-related stressors; (c) quantitative and qualitative job demands; (d) lack of job resources; and (e) personality traits. Consequences involved (a) individual’s unfavorable quality of life; (b) negative impact on the organization; and (c) poor services quality. Although the Maslach Burnout Inventory (MBI) is perceived as an ideal tool to measure burnout and hence, it is used worldwide, whether this instrument fits to measure this concept for nurses has still not yet been verified and thus further research is needed. Conclusions By proposing a comprehensive definition of the concept, this analysis contributes to recognition of the process of OB of nurses. All nurses are vulnerable to OB. Hence, burnout in nursing needs to be recognized as a critical factor in the delivery of safe patient care. It proposes that the prevention of OB would be achieved through team communication training, mindfulness group, education, etc.

ADP-ribosylation factor 6 (ARF6) is a well-studied protein that is involved in multiple biological functions including cell migration and invasion. The mechanism by which ARF6 regulates the migration and invasion of upper tract urothelial carcinoma (UTUC) is still unknown. MiR-145-5p is a tumor suppressor microRNA, which is downregulated in several cancer types. We aimed to elucidate the molecular mechanism underlying the regulation of ARF6 by miR-145-5p in UTUC. ARF6 expression was observed to be higher in UTUC tissues than paired adjacent normal tissues. A reverse correlation between ARF6 and miR-145-5p was found in UTUC tissues. MiR-145-5p inhibited ARF6 expression by directly targeting its 3'-UTR. The functional studies indicated that ARF6 expression reversed the miR-145-5p-reduced tumor cell migration and invasion. Notably, miR-145-5p reduced MMP2, N-cadherin, FAK and MMP7, and elevated E-cadherin protein levels in vitro; however, the above effects were reversed by ARF6. Further, the expression of epithelial-to-mesenchymal transition (EMT) markers and cell invasion was suppressed by knocking down MMP7 in UTUC cells. These findings suggest that miR-145-5p may suppress UTUC cell motility and invasion by targeting ARF6/MMP7 through EMT.

Patients with upper tract urothelial carcinoma (UTUC) have a high prevalence of comorbidities. However, the prognostic impact of comorbidities in these patients is not well studied. We aimed to outline the comorbidity burden in UTUC patients and investigate its relationship with overall survival (OS), cancer-specific survival (CSS), and progression-free survival (PFS). We retrospectively reviewed the clinicopathological data of 409 non-metastatic UTUC patients who received radical nephroureterectomy between 2000 and 2015. The comorbidity burden was evaluated using the Adult Comorbidity Evaluation-27 (ACE-27). Kaplan-Meier survival analysis showed that high ACE-27 grade was significantly associated with worse PFS, CSS, and OS. In multivariate Cox regression and competing risk analyses, we found that ACE-27 grade, tumor stage, and tumor grade were independent prognosticators of OS, CSS, and PFS. We combined these three significant factors to construct a prognostic model for predicting clinical outcomes. A receiver operating characteristic curve revealed that our prognostic model had high predictive performance. The Harrel’s concordance indices of this model for predicting OS, CSS, and PFS were 0.81, 0.85, and 0.85, respectively. The results suggest that the UTUC patient comorbidity burden (ACE-27) provides information on the risk for meaningful clinical outcomes of OS, CSS, and PFS.

BackgroundThe advantage of adjuvant chemotherapy for upper urinary tract urothelial cancer (UTUC) has been reported, whereas its impact on upper tract cancer with variant histology remains unclear. We aimed to answer the abovementioned question with our real-world data.Design, Setting, and ParticipantsPatients who underwent radical nephroureterectomy (RNU) and were confirmed to have variant UTUC were retrospectively evaluated for eligibility of analysis. In the Taiwan UTUC Collaboration database, we identified 245 patients with variant UTUC among 3,109 patients with UTUC who underwent RNU after excluding patients with missing clinicopathological information.InterventionThose patients with variant UTUC were grouped based on their history of receiving adjuvant chemotherapy or not.Outcome Measurements and Statistical AnalysisPropensity score matching was used to reduce the treatment assignment bias. Multivariable Cox regression model was used for the analysis of overall, cancer-specific, and disease-free survival.Results and LimitationsFor the patients with variant UTUC who underwent adjuvant chemotherapy compared with those without chemotherapy, survival benefit was identified in overall survival in univariate analysis (hazard ratio (HR), 0.527; 95% confidence interval (CI), 0.285–0.973; p = 0.041). In addition, in multivariate analysis, patients with adjuvant chemotherapy demonstrated significant survival benefits in cancer-specific survival (OS; HR, 0.454; CI, 0.208–0.988; p = 0.047), and disease-free survival (DFS; HR, 0.324; 95% CI, 0.155–0.677; (p = 0.003). The main limitations of the current study were its retrospective design and limited case number.ConclusionsAdjuvant chemotherapy following RNU significantly improved cancer-related survivals in patients with UTUC with variant histology.

Intestinal ischemia/reperfusion (I/R) injury (IIRI) is associated with high prevalence and mortality rate. Recently, mesenchymal stem cell (MSC) therapy attracted more attentions. However, the function and regulatory mechanism of MSC-derived exosomal miRNAs during IIRI remain largely uninvestigated. The in vitro and in vivo IIRI models were established. MSC were characterized by immunofluorescent staining and flow cytometry. Purified exosomes were characterized by transmission electron microscopy (TEM), flow cytometry, and western blot. The expression of key molecules was detected by western blot and qRT-PCR. CCK-8, TUNEL, and transepithelial electrical resistance (TER) assays were employed to assess cell viability, apoptosis, and intestinal integrity, respectively. Pre-miR-34A m

Background and purpose The aim of this study is to decipher the underlying mechanisms of CCAAT/enhancer‐binding protein delta (CEBPD)‐enhanced glycolysis as well as the biological significance of CEBPD and MYC coamplification in urothelial carcinoma (UC). Methods In vitro analyses were conducted to examine the effects of altered CEBPD or MYC expression on UC cells. The in vivo effects of CEBPD overexpression in a high‐glucose environment on tumour growth were investigated in xenografted induced diabetic severe combined immunodeficiency/beige mice. Data mining was used to cross‐validate the associations between CEBPD and MYC copy number and transcriptional expression, quantitative reverse transcription‐polymerase chain reaction, immunohistochemistry, chromogenic in situ hybridization, and in situ hybridization targeting microRNA were performed on 635 UC patient samples and xenograft samples. UC patient survival in relation to diabetes was validated by using the National Health Insurance Research Database. Results CEBPD and MYC coamplification (29.6%) occurred at a high frequency, MYC expression promoted chromosomal instability, facilitating CEBPD copy number gain and expression. CEBPD promoted glucose uptake and lactate production by upregulating SLC2A1 and HK2, leading to mitochondrial fission, increased extracellular acidification rate and decreased oxygen consumption rate to fuel cell growth. CEBPD upregulated HK2 expression through multiple regulation pathways including MYC stabilization, suppression of FBXW7 transactivation and MYC‐independent transcriptional suppression of hsa‐miR‐429. Clinical and xenografted experiments confirmed the growth advantage of CEBPD in relation to glucose metabolic dysregulation and the significant correlations between the expression of these genes. Conclusions We confirmed that CEBPD has an oncogenic role in UC by activating AKT signalling and initiating metabolic reprogramming from mitochondrial oxidative phosphorylation to glycolysis to satisfy glucose addiction. These novel CEBPD‐ and MYC‐centric multilayered positive feedback loops enhance cancer growth that could complement theranostic approaches., • MYC and CEBPD coamplification predicts poor outcomes in urothelial carcinoma. • MYC enhances amplification‐driven CEBPD expression and CEBPD stabilize MYC protein through transcriptional suppression of FBXW7, forming a positive feedback loop. • CEBPD facilitates the switch from mitochondrial oxidative phosphorylation to glycolysis in both MYC‐dependent and a Myc‐independent CEBPD ‐ hsa‐miR‐429 ‐ HK2 regulatory axis that confers pro‐proliferative effect aggravated by high glucose condition.

To study the relationship between oral disease and depressive symptoms in middle-aged and older adult populations in China.The data from the China Health and Retirement Longitudinal Study (CHARLS) done between 2013 and 2015 were analyzed. A total of 3828 middle-aged and older adults showing no depressive symptoms in an assessment with the 10-item Centre for Epidemiological Studies Depression Scale (CES-D-10) were selected as the subjects of observation, and oral disease was taken as the dependent variable. Changes in depressive symptoms in the population were tracked in 2015, and the Cox proportional hazards model was used to estimate the relationship between oral diseases and depressive symptoms.The detection rate of depressive symptoms was 29.3% in middle-aged and older adults with oral diseases, and that of middle-aged and older adults without oral diseases was 20.4%, the difference being statistically significant (Oral diseases in the middle-aged and older adult populations tended to lead to depressive symptoms, and women showed higher rate than men did. Prevention and control measures should be taken actively in the course of oral disease treatment to promote mental health of middle-aged and older adults.

The clinical efficacy of adjuvant chemotherapy in upper tract urothelial carcinoma (UTUC) is unclear. We aimed to assess the therapeutic outcomes of adjuvant chemotherapy in patients with advanced UTUC (pT3-T4) after radical nephroureterectomy (RNU). We retrospectively reviewed the data of 2108 patients from the Taiwan UTUC Collaboration Group between 1988 and 2018. Comprehensive clinical features, pathological characteristics, and survival outcomes were recorded. Univariate and multivariate Cox proportional hazards models were used to evaluate overall survival (OS), cancer-specific survival (CSS), and disease-free survival (DFS). Of the 533 patients with advanced UTUC included, 161 (30.2%) received adjuvant chemotherapy. In the multivariate analysis, adjuvant chemotherapy was significantly associated with a reduced risk of overall death (hazard ratio (HR), 0.599; 95% confidence interval (CI), 0.419–0.857; p = 0.005), cancer-specific mortality (HR, 0.598; 95% CI, 0.391–0.914; p = 0.018), and cancer recurrence (HR, 0.456; 95% CI, 0.310–0.673; p < 0.001). The Kaplan–Meier survival analysis revealed that patients receiving adjuvant chemotherapy had significantly better five-year OS (64% vs. 50%, p = 0.002), CSS (70% vs. 62%, p = 0.043), and DFS (60% vs. 48%, p = 0.002) rates compared to those who did not receive adjuvant chemotherapy. In conclusion, adjuvant chemotherapy after RNU had significant therapeutic benefits on OS, CSS, and DFS in advanced UTUC.

Taiwan has the highest incidence of upper tract urothelial carcinoma (UTUC) worldwide. Although many pathological factors can predict the prognosis of UTUC, previous studies have rarely discussed perineural invasion (PNI). Therefore, we aimed to investigate the effect of PNI on a well-established cohort of patients with UTUC.This retrospective study included 803 patients with non-metastatic UTUC who underwent radical nephroureterectomy between June 2000 and August 2019. Demographic and clinicopathological parameters, including PNI, were collected for analysis. Using the Kaplan-Meier method and Cox proportional hazards model, we evaluated the significance of PNI with respect to progression-free survival (PFS), cancer-specific survival (CSS), and overall survival (OS).The median follow-up was 30.9 months, and there were 83 cases of PNI (10.3%). PNI-positive patients had unfavorable pathological features, including high pT stage, positive lymph node involvement, high tumor grade, and more lymphovascular invasion (all p 0.001). Kaplan-Meier analysis showed that PNI was significantly associated with PFS, CSS, and OS (all p 0.00001), and when combined with lymphovascular invasion, patients could be divided into groups with distinct survival rates (all p 0.00001). In multivariate analysis, PNI was an independent factor leading to worse PFS (hazard ratio [HR] 1.72, 95% confidence interval [CI] 1.19-2.50; p = 0.004), CSS (HR 2.54, 95% CI 1.58-4.10; p = 0.0001), and OS (HR 1.78, 95% CI 1.19-2.65; p = 0.005).We demonstrated an association between PNI and the prognosis of UTUC. Routine assessment of PNI in UTUC with standardized protocols may help achieve better risk stratification and subject selection for perioperative treatment.

CSN6 is a subunit of the constitutive photomorphogenesis 9 (COP9) signalosome (CSN). CSN is involved in cellular and developmental processes such as signal transduction, transcriptional activation, cell cycle control, and tumorigenesis. CSN6 is highly expressed in several human cancers, including colorectal cancer, and breast cancer. However, no previous research has elaborated on the relationship between CSN6 expression and survival in patients with upper tract urothelial carcinoma (UTUC). Therefore, the purpose of this study is to evaluate the clinical significance of CSN6 in UTUC. CSN6 expression in 89 patients with UTUC enrolled in this study was examined using immunohistochemistry. The associations between CSN6 expression and clinicopathological variables were analyzed. CSN6 expression was significantly correlated with patients with high pathological stage (P = .006), male gender (P = .025), and high serum creatinine levels (P = .014). In univariate and multivariable analysis, high CSN6 expression was associated with a higher bladder recurrence (P = .005) and poor cancer‐specific survival (P = .001) for UTUC. In conclusion, CSN6 expression is a potential biomarker for predicting cancer recurrence and clinical survival in UTUC. Further research is necessary to investigate its role in the progression of UTUC.

Background Natural Killer T–Cell Lymphoma (NKTCL) is a subtype of Non‐Hodgkin's Lymphoma, and its morbidity is ranked the first of T‐Cell Lymphoma. Hippo signaling pathway is involved in the pathogenesis of tumors. However, the role of Hippo signaling pathway in the oncogenesis of NKTCL still remains unclear. Methods The expressions of mammalian sterile 20‐like kinase 1 (MST1) and Yes‐associated protein (YAP) were investigated by RT‐PCR and Western blotting. Cell viability was detected by MTT assays. Cell cycle and cell apoptosis were determined by flow cytometry. Cell proliferative capacity was detected by colony formation assay. Nude mice xenograft models were established and the tumor sections were analyzed by immunohistochemistry (IHC) staining. Results The expression of MST1 was significantly down‐regulated in NKTCL tissues (n = 30) and cell lines, while the expression of YAP was significantly up‐regulated, and the phosphorylation of YAP was inhibited. Overexpression of MST1, knockdown of YAP, or verteporfin (VP) treatment could inhibit cell proliferation, and promote cell cycle arrest and apoptosis in NKTCL cells, while knockdown of MST1 and overexpression of YAP promoted cell proliferation. Additionally, Bcl‐2/Bax ratio and downstream effectors of Hippo signaling pathway (c‐myc, survivin, cyclinD1, CTGF, and TEAD) were significantly decreased when MST1 was overexpressed and YAP was knocked down or after VP treatment. Furthermore, our mice model demonstrated that activation of Hippo signal pathway suppressed the tumorigenesis of NKTCL. Conclusion The activation of Hippo signal pathway via overexpressing MST1 or down‐regulating YAP can inhibit the tumorigenesis of NKTCL.

To assess temporal patterns and regional differences in the incidence rate, and factors associated with survival of urinary tract urothelial carcinoma.The medical records of 8830 patients with new diagnoses of urinary tract urothelial carcinoma in the years 2001-2010 were retrieved from Taiwan National databases. Temporal trends, regional disparity and related survival factors were evaluated using the Cochran-Armitage trend test, local Moran's I statistic and log-rank test, respectively.The annual urinary tract urothelial carcinoma incidence rates (standardized by age) were steady at approximately 3.14-3.41 per 100 000 person-years. Notably, women had a significantly higher annual urinary tract urothelial carcinoma incidence than men in most of the years studied (range of female-to-male annual standardized rate ratio: 2.08-3.25), and diabetes prevalence in urinary tract urothelial carcinoma increased significantly from 12.3% to 23.4% per year over the 10 years. High urinary tract urothelial carcinoma incidence cluster areas other than the latest endemic area of "blackfoot disease" were newly identified by local Moran's I statistic (P 0.05). Furthermore, older age, male sex, end-stage kidney disease and more advanced tumor grade were associated with lower 5-year overall survival probabilities in the 2001-2015 cohort.The incidence and survival of urinary tract urothelial carcinoma over the decade 2001-2010 were different according to population and regional features. Various urinary tract urothelial carcinoma screening, prevention, treatment and care plans should be developed depending on age, sex, comorbidity and area of residence.

[Background] To reveal the effect of potassium deficiency on the growth and development of pakchoi in cold and dry areas.[Results] The effect of potassium deficiency on the growth status of P. pakchoi in cold and dry areas was significant. P. pakchoi treated with potassium-free nutrient solution had the best growth, the largest number of leaves, leaf length, leaf width, leaf area, root length and weight; P. pakchoi treated with 100% potassium deficiency had the smallest plant, leaf length, leaf width, leaf area, root length and weight; P. pakchoi treated with potassium deficiency 50% had the middle growth and development status, and the root ratio was the smallest in d 21.[Conclusion] Potassium can effectively promote the growth and development of pakchoi in cold and dry areas, increase its root length, leaf width, leaf area, weight, etc. The quality of the upper part and the underground part of d,21 of pakchoi treated with deficiency is the most different.

As all-trans retinoic acid (ATRA) and arsenic trioxide (ATO) are widely accepted in treating acute promyelocytic leukemia (APL), deescalating toxicity becomes a research hotspot. Here, we evaluated whether chemotherapy could be replaced or reduced by ATO in APL patients at different risks. After achieving complete remission with ATRA-ATO–based induction therapy, patients were randomized (1:1) into ATO and non-ATO groups for consolidation: ATRA-ATO versus ATRA–anthracycline for low-/intermediate-risk patients, or ATRA-ATO–anthracycline versus ATRA–anthracycline–cytarabine for high-risk patients. The primary end point was to assess disease-free survival (DFS) at 3 y by a noninferiority margin of –5%; 855 patients were enrolled with a median follow-up of 54.9 mo, and 658 of 755 patients could be evaluated at 3 y. In the ATO group, 96.1% (319/332) achieved 3-y DFS, compared to 92.6% (302/326) in the non-ATO group. The difference was 3.45% (95% CI –0.07 to 6.97), confirming noninferiority (P < 0.001). Using the Kaplan–Meier method, the estimated 7-y DFS was 95.7% (95% CI 93.6 to 97.9) in ATO and 92.6% (95% CI 89.8 to 95.4) in non-ATO groups (P = 0.066). Concerning secondary end points, the 7-y cumulative incidence of relapse (CIR) was significantly lower in ATO (2.2% [95% CI 1.1 to 4.2]) than in non-ATO group (6.1% [95% CI 3.9 to 9.5], P = 0.011). In addition, grade 3 to 4 hematological toxicities were significantly reduced in the ATO group during consolidation. Hence, ATRA-ATO in both chemotherapy-replacing and -reducing settings in consolidation is not inferior to ATRA–chemotherapy (https://www.clinicaltrials.gov/, NCT01987297).

In quantum and quantum-inspired machine learning, the very first step is to embed the data in quantum space known as Hilbert space. Developing quantum kernel function (QKF), which defines the distances among the samples in the Hilbert space, belongs to the fundamental topics for machine learning. In this work, we propose the rescaled logarithmic fidelity (RLF) and non-parametric semi-supervised learning in the quantum space, which we name as RLF-NSSL. The rescaling takes advantage of the non-linearity of the kernel to tune the mutual distances of samples in the Hilbert space, and meanwhile avoids the exponentially-small fidelities between quantum many-qubit states. Being non-parametric excludes the possible effects from the variational parameters, and evidently demonstrates the advantages from the space itself. We compare RLF-NSSL with several well-known non-parametric algorithms including naive Bayes classifiers, k-nearest neighbors, and spectral clustering. Our method exhibits better accuracy particularly for the unsupervised case with no labeled samples and the few-shot cases with small numbers of labeled samples. With the visualizations by t-stochastic neighbor embedding, our results imply that the machine learning in the Hilbert space complies with the principles of maximal coding rate reduction, where the low-dimensional data exhibit within-class compressibility, between-class discrimination, and overall diversity. Our proposals can be applied to other quantum and quantum-inspired machine learning, including the methods using the parametric models such as tensor networks, quantum circuits, and quantum neural networks., Comment: 8 pages, 5 figures

A photoredox-catalyzed regio- and stereoselective trifluoroethylation reaction of enamides using commercially available 2,2,2-trifluoroethyl iodide as trifluoroethylating agents has been developed, furnishing geometrically defined and synthetically and physiochemically pivotal β-trifluoroethylated enamides bearing a diverse range of functional groups.

Laparoscopic radical nephroureterectomy (LNU) has gradually become the new standard treatment for localized upper tract urothelial cancer (UTUC). With more blunt dissection and tactile sensation, hand-assisted LNU might shorten the operative time compared with the pure laparoscopic approach. However, whether the use of the hand-assisted or the pure laparoscopic approach has an effect on oncological outcomes remains unclear.We retrospectively identified 629 patients with non-metastatic UTUC who underwent hand-assisted (n = 515) or pure LNU (n = 114) at 9 hospitals in Taiwan between 2004 and 2019. Overall survival, cancer-specific survival, recurrence-free survival, and bladder recurrence-free survival were compared between these two groups using inverse-probability of treatment weighting (IPTW) derived from the propensity scores for baseline covariate adjustment.The median follow-up period was 32.9 and 28.7 months in the hand-assisted and the pure groups, respectively. IPTW-adjusted Cox proportional hazards models showed that the laparoscopic approach (pure vs. hand-assisted) was not significantly associated with all-cause mortality (HR 0.79, 95% CI 0.49-1.24, p = 0.304), cancer-specific mortality (HR 0.88, 95% CI 0.51-1.51, p = 0.634), or extra-vesical recurrence (HR 0.65, 95% CI 0.41-1.04, p = 0.071). However, the pure laparoscopic approach was significantly associated with lower intra-vescial recurrence (HR 0.64, 95% CI 0.43-0.96, p = 0.029) for patients who underwent LNU. Kaplan-Meier curves also revealed that the pure laparoscopic approach was associated with better bladder recurrence-free survival compared with the hand-assisted laparoscopic approach in both the original cohort and the IPTW-adjusted cohort (log-rank p = 0.042 and 0.027, respectively).The performance of hand-assisted or pure LNU does not significantly affect the all-cause mortality, cancer-specific mortality, or extra-vesical recurrence for patients with non-metastatic UTUC. However, the hand-assisted laparoscopic approach could increase the risk of intra-vesical recurrence for patients who undergo LNU.

Objective High incidence of upper urinary tract urothelial carcinoma has been reported in South- Western area of Taiwan, where arsenic water contamination was considered to be the main cause. However, there is no definite proof to show the correlation between the arsenic water contamination and upper urinary tract urothelial carcinoma. To investigate the clinical and epidemiological features of the patients with upper urinary tract urothelial carcinoma between arsenic water endemic and non-endemic areas, we analyzed patients in terms of characteristics, stratified overall survival, disease-free survival and cancer-specific survival Method The records of a total 1194 patients diagnosed with upper urinary tract urothelial carcinoma were retrospectively reviewed. Clinical data and current medical status were collected from medical records. Statistical analyses were performed to determine the clinical variables and stratified survival curves between endemic and non-endemic groups. Results Female predominance was revealed in both endemic and non-endemic groups (Male:Female=1:1.2- 1.4). No statistical differences were found in histological types, staging and tumor size among two groups. Nonetheless, patients with characteristics of aging and having end stage renal disease outnumbered in non-endemic group while higher prevalence of previous bladder tumor and more ureteral tumor were found in endemic group. Adjusted stratified cumulative survival curves suggested poorer prognosis fashion in endemic patients, especially in disease free survival of early stage disease. Conclusions Higher mortality rate with more previous bladder cancer history and ureteral tumor were seen in patients with upper urinary tract urothelial carcinoma residing in arsenic water contamination area. This may attribute to the long-term carcinogenesis effect of arsenic underground water.

Urothelial carcinoma (UC), including upper tract urothelial carcinoma (UTUC) and urinary bladder urothelial carcinoma (UBUC), is a common malignant disease in developed countries. Oncogenic metabolic lesions have been associated with UC development. Methods: Using data mining, a series of studies were performed to study the involvement of SLC14A1 in UC specimens, animal models and UC-derived cell lines. Results: In two cohorts of UTUC (n = 340) and UBUC (n = 295), the SLC14A1 protein level was an independent prognostic factor. Epigenetic silencing contributed to SLC14A1 downregulation in UCs. Total and membranous SLC14A1 played tumor suppressive roles through the inhibition of cell proliferation and metastasis in distinct UC-derived cells and animal models. Functional SLC14A1 prevented the accumulation of arginine and urea, enhanced mitochondrial fusion and aerobic respiration, inhibited glycolysis by altering the expression levels of several related proteins and sensitized arginine-deprivation treatment in ASS1-deficient UC-derived cells. In vitro and in vivo, SLC14A1 inhibited the mTOR signaling pathway and subsequently tumorigenesis, supported by reduced arginine concentrations in vitro. Nuclear SLC14A1 transrepressed HK2 and DEGS1 genes via recruitment of HDAC1 and/or SIN3A to maintain metabolic homeostasis and thereafter impeded tumorigenesis. Conclusion: Clinical associations, animal models and in vitro indications provide solid evidence that the SLC14A1 gene is a novel tumor suppressor in UCs. Total and membranous SLC14A1 prevents urea and arginine accumulation via the mTOR signaling pathway. Nuclear SLC14A1 recruits HDAC1 to transrepress oncometabolite genes.

The metabolic syndrome was associated with bladder cancer in the previous studies. However, there have no large-scale cohort studies to elucidate the relationship between metabolic syndromes and urothelial carcinoma including urinary bladder urothelial carcinoma (UBUC) and upper tract urothelial carcinoma (UTUC).We analyze a population-based cohort study by using physical examination data and diagnosis of UC from the Taiwan Cancer Registry Database. Differences in demographic and clinical characteristics among UTUC and non-UTUC groups, UBUC and non-UBUC groups were compared. Odds ratios (ORs) for determining risk factors were estimated through the multiple logistic regression model.A total of 557,063 records for 211,319 participants which consisted of 31 UTUC and 309 UBUC met the eligibility criteria in this study. Our results showed that female are more likely to develop UTUC than male. As opposed to UTUC, male are more likely to develop UBUC than female. It also showed that participants smoked or chewed betel quid daily are more likely to develop UBUC. Age and estimated glomerular filtration rate (eGFR) are significantly increased the risk of developing UTUC. The association between the eGFR and risk of UTUC is stronger (P 0.001) for eGFR 45 (vs. eGFR ≥ 75, OR = 6.795; 95% CI 2.901-15.917). Metabolic syndrome is related to higher risk of UBUC incidence [OR was 1.373 (95% CI 1.104-1.707)].There was a significant relationship between the incidence of UBUC and metabolic syndrome. Renal function impairment presents higher risk in both UBUC and UTUC development.

Background The pandemic of COVID-19 has disrupted the clinical pathway for patients with suspected upper tract urothelial carcinoma (UTUC). This aims to investigate the optimal management of UTUC during the pandemic by determining 1) Whether a three-month delay of RNU leads to worsened overall survival, 2) Whether radical nephroureterectomy (RNU) can be performed without prior diagnostic ureteroscopy (URS). Methods Consecutive patients with RNU performed for suspected UTUC in four hospitals in Hong Kong and Taiwan were included. Patients with histologically proven UTUC and with RNU performed within one year were dichotomized into early (≤3 months) and delayed (>3 months) RNU groups. Diagnostic performances of predictive models based on pre-URS factors (gross haematuria, suspicious or malignant urine cytology, and filling defect or contrast-enhancing mass on computed tomography), with or without URS, were analysed using receiver operating characteristics and area under curve (AUC). Overall survival was analysed using Kaplan-Meier method and multivariate Cox regression analysis. Results Between 2000 and 2019, 665 patients underwent RNU, and 491 of them had prior diagnostic URS. The early RNU group had a better overall survival (P = 0.015). Early RNU was associated with a better overall survival upon multivariate analysis (HR 1.55, 95% CI 1.03–2.33, P = 0.035). Large tumour size, multi-focal tumour, T2 or above disease, and positive nodal status were associated with a poorer overall survival. A combination of any 2 out of the 3 pre-URS factors achieved a positive predictive value of 99.5 to 100%. Presence of all 3 pre-URS factors achieved an AUC of 0.851 with URS, and AUC of 0.809 without URS. Conclusions A delay of RNU for over 3 months was associated with poorer overall survival and has to be avoided despite the current COVID-19. We can also consider direct RNU based on clinical factors alone. This also avoids URS hospitalization and expedites the clinical pathway of UTUC.

In this work, commercial anatase TiO2 powders were modified using ultrathin Fe2O3 layer by atomic layer deposition (ALD). The ultrathin Fe2O3 coating having small bandgap of 2.20 eV can increase the visible light absorption of TiO2 supports, at the meantime, Fe2O3/TiO2 heterojunction can effectively improve the lifetime of photogenerated electron–hole pairs. Results of ALD Fe2O3 modified TiO2 catalyst, therefore, showed great visible light driven catalytic degradation of methyl orange compared to pristine TiO2. A 400 cycles of ALD Fe2O3 (~ 2.6 nm) coated TiO2 powders exhibit the highest degradation efficiency of 97.4% in 90 min, much higher than pristine TiO2 powders of only 12.5%. Moreover, an ultrathin ALD Al2O3 (~ 2 nm) was able to improve the stability of Fe2O3-TiO2 catalyst. These results demonstrate that ALD surface modification with ultrathin coating is an extremely powerful route for the applications in constructing efficient and stable photocatalysts.

Inconsistent prognostic implications of body mass index (BMI) in upper tract urothelial carcinoma (UTUC) have been reported across different ethnicities. In this study, we aimed to analyze the oncologic role of BMI in Asian and Caucasian patients with UTUC.We retrospectively collected data from 648 Asian Taiwanese and 213 Caucasian American patients who underwent radical nephroureterectomy for UTUC. We compared clinicopathologic features among groups categorized by different BMI. Kaplan-Meier method and Cox regression model were used to examine the impact of BMI on recurrence and survival by ethnicity.According to ethnicity-specific criteria, overweight and obesity were found in 151 (23.2%) and 215 (33.2%) Asians, and 79 (37.1%) and 78 (36.6%) Caucasians, respectively. No significant association between BMI and disease characteristics was detected in both ethnicities. On multivariate analysis, overweight and obese Asians had significantly lower recurrence than those with normal weight (HR 0.631, 95% CI 0.413-0.966; HR 0.695, 95% CI 0.493-0.981, respectively), and obesity was an independent prognostic factor for favorable cancer-specific and overall survival (HR 0.521, 95% CI 0.342-0.794; HR 0.545, 95% CI 0.386-0.769, respectively). There was no significant difference in outcomes among normal, overweight and obese Caucasians, but obese patients had a relatively poorer 5-year RFS, CSS, and OS rates of 52.8%, 60.5%, and 47.2%, compared to 54.9%, 69.1%, and 54.9% for normal weight patients.Higher BMI was associated with improved outcomes in Asian patients with UTUC. Interethnic differences could influence preoperative counseling or prediction modeling in patients with UTUC.

Endocrine disrupting chemicals (EDCs) can be present as trace-level organic pollutants in aquatic environments and are difficult to measure and remove. In this study, a method was developed using a modified quartz crystal microbalance (QCM) to investigate the adsorption of EDCs by zeolite filter. Bisphenol A (BPA), oestrone (E1), oestradiol (E2), and sulfamethoxazole (SMZ) were selected as four representative endocrine disruptors in a water environment and their adsorption on zeolite was measured by QCM in real-time. The adsorption results were well described by a pseudo-first-order kinetic model and by a Sips isotherms model. The adsorption of the four adsorbents is related to their molecular structure, molecular polarity, and chargeability. The removal rate of EDCs by zeolite for different initial concentrations appeared to plateau, with the removal rates of the four selected EDCs all above 80% except for the maximum initial concentration. Changes of pH and ionic strength had no effect on the adsorption capacity of the four EDCs, with a removal rate of about 90%. However, the response time at pH 5.50 was about 300 s faster than that at pH 8.50 and the addition of electrolyte shortened the mass response time of several organic compounds on QCM.

BACKGROUND Long noncoding RNAs (lncRNAs) recently have been implicated in the pathological processes of cardiovascular diseases. In this study, LncRNADisease database and PubMed database were used to screen myocardial infraction (MI)-related lncRNAs and to investigate the diagnostic role of lncRNAs in ST-segment elevation myocardial infraction (STEMI). MATERIAL AND METHODS Forty-six patients with STEMI and 40 healthy controls were included in the study. Venous blood samples acquired at different time points and the expression levels of lncRNAs in plasma were measured by qRT-PCR. In addition, other blood samples were collected before and after percutaneous coronary intervention (PCI). Correlation analysis and receiver operating characteristic (ROC) curve were used to assess the diagnosis value of the markers. All included patients were followed up for 12±1 months. RESULTS Nine MI-related lncRNAs were selected from the database. The qRT-PCR results showed that the expression of hypoxia inducible factor 1A antisense RNA 2 (aHIF), member 1 opposite strand/antisense transcript 1 (KCNQ1OT1), and mitochondrial long noncoding RNA uc022bqs.1 (LIPCAR) were significantly increased in patients with STEMI compared to the control patients. The ROC curve showed that LIPCAR (AUC=0.782, 95% CI: 0.707-0.0.894) had better diagnostic accuracy. Moreover, correlation analysis indicated that LIPCAR were positively correlated with myocardial enzymes and negatively correlated with left ventricular ejection fraction. The level of LIPCAR in STEMI patients after PCI was lower (P

The relation of dialysis to tumor recurrence in patients with upper tract urothelial cancer (UTUC) is unknown; however, a limited number of small-scale studies suggest that patients with renal diseases prior to UTUC are more likely to exhibit bladder recurrence. We performed a population-based analysis to determine the effect of dialysis on bladder recurrence for patients with UTUC. This retrospective cohort study included patients diagnosed with UTUC (2002–2007) from the Taiwan National Cancer Registry and divided them into two groups—dialysis and non-dialysis groups. These patients were followed up until bladder recurrence, death, or the end of 2010. Competing risk analyses adjusting covariates and death were applied to determine the relation of dialysis and bladder recurrence. Of the 5141 eligible patients, 548 (10.7%) were undergoing dialysis. The cumulative bladder recurrence was significantly higher in the dialysis group than in the non-dialysis group (29% vs. 21%, modified log-rank p
