OBJECTIVE Presence of lymph node (LN) metastasis in bladder cancer (BCa) is a main risk factor for tumor recurrence after radical cystectomy (RC). Molecular analysis facilitates detection of small-volume LN metastases with higher sensitivity than standard histopathology. The aim of the present study was to establish molecular LN analysis in BCa patients undergoing RC with lymph node dissection (LND) and to determine its ability to predict tumor recurrence. PATIENTS AND METHODS Five transcripts with overexpression in BCa (FXYD3, KRT17, KRT20, SPINK1, UPKII) were evaluated for molecular LN analysis. We included 76 BCa patients from the prospective, randomized surgical phase-III trial (LEA AUO AB 25/02, NCT01215071) investigating extended vs. limited LND at RC. The primary endpoint was recurrence-free survival (RFS). As control, 136 LNs from 45 patients without BCa were analyzed to determine a threshold for pathologic gene expression. RESULTS About 1,319 LNs were investigated with molecular and histopathologic eeatment. BACKGROUND Healthy diet is essential in the management of chronic kidney disease (CKD) and preventing related comorbidities. Food outlet access has been studied in the general population; however, the influence of the local food environment on dietary intake among people with CKD has not been evaluated. OBJECTIVES This study examined the associations of food outlet density and type of outlets with dietary intake in a multicenter cohort of racially and ethnically diverse patients with CKD. METHODS The Chronic Renal Insufficiency Cohort Study is a multicenter prospective study of patients with CKD that used a validated food frequency questionnaire to capture dietary intake at the baseline visit. https://www.selleckchem.com/products/ABT-888.html This is a cross-sectional analysis of 2,484 participants recruited in 2003-2006 from seven Chronic Renal Insufficiency Cohort Study centers. Food outlet data were used to construct a count of the number of fast-food restaurants, convenience stores, and grocery stores per 10,000 population for each geocoded census block nutrient intakes differed by outlet availability; however, there were no strong associations with type of food outlet. This should be considered when developing food-focused public health policies. BACKGROUND Most previous studies have examined the associations between carotenoids and anthropometrics with cross-sectional designs. Few studies have investigated the associations between serum carotenoids and fat mass and fat distribution (general vs central type). OBJECTIVE This study aimed to explore the associations of serum carotenoids with body fat and fat distribution in Chinese adults. DESIGN Cross-sectional and longitudinal analyses of a prospective, community-based cohort were performed. PARTICIPANTS/SETTING There were 4,048 participants aged 40 to 75 years recruited in the Guangzhou Nutrition and Health Study from 2008 to 2013. MAIN OUTCOME MEASURES Serum carotenoids were assessed at baseline. Anthropometrics, fat mass (FM), and percentage FM (%FM) over the total body, trunk, limbs, and android and gynoid regions were obtained by dual-energy x-ray absorptiometry for 3,002 participants between 2011 and 2013 and for 2,537 participants after 3.1 years. STATISTICAL ANALYSIS Cross-sectional and longituecially for cross-sectional analyses. CONCLUSIONS Serum carotenoid concentrations are inversely associated with body fat, especially in the abdominal region, in Chinese adults. OBJECTIVE The present meta-analysis is intended to assess the association between NSCL/P risk and methylenetetrahydrofolate reductase (MTHFR) A1298C polymorphism in case-control studies. MATERIALS AND METHODS The Web of Science, PubMed?/Medline, Scopus, and Cochrane Library databases were searched for related articles published by April 2019. Review Manager 5.3 was applied to measure the odds ratios (ORs) with 95% confidence interval (CI) in the analyses assessing the strength of the association between A1298C polymorphism and NSCL/P risk. Results Sixteen studies were involved and analysed in this meta-analysis. Altogether, the reviewed articles included 2677 NSCL/P patients and 3669 controls. The pooled ORs of the allele, homozygote, heterozygote, dominant, and recessive models were 1.11 (95% CI 0.94, 1.30; P=0.21), 1.14 (95% CI 0.94, 1.37; P=0.18), 0.98 (95% CI 0.80, 1.20; P=0.87), 1.03 (95% CI 0.86, 1.22; P=0.79), and 1.18 (95% CI 0.99, 1.41; P=0.07), respectively. The analysis did not identify any significant association between the polymorphism and the risk of NSCL/P in any ethnicity or source of controls. CONCLUSIONS This meta-analysis revealed that A1298C polymorphism is not associated with NSCL/P susceptibility, and the subgroup analyses based on ethnicity and the source of cases further confirmed this result. BACKGROUND Water irrigant is discouraged in ureteroscopy due to risks demonstrated in more invasive endoscopic procedures. However, water is not well studied in ureteroscopy and may provide better visualization than standard saline. OBJECTIVE To determine whether water irrigant increases the risk of hyponatremia compared with saline and provides better visualization in ureteroscopy. DESIGN, SETTING, AND PARTICIPANTS A randomized, prospective, double-blinded trial was conducted. In 2017, eligible adult ureteroscopy patients at a university hospital were recruited for the study. INTERVENTION Participants randomized to water or saline irrigant in ureteroscopy. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Serum sodium and osmolality, body temperature, subjective surgeon visualization, and objective turbidity clarity were analyzed. Chi-square or Fisher's exact tests for categorical variables and analysis of variance test for continuous variables were performed. RESULTS AND LIMITATIONS A total of 121 individuals (, which aid surgeon visualization, in ureteroscopy, which can treat kidney stones. We found that water irrigant does not reduce blood sodium levels significantly compared with saline in ureteroscopy and provides better visualization. V.INTRODUCTION AND OBJECTIVES Percutaneous coronary intervention (PCI) for aorto-ostial chronic total coronary occlusion (CTO) can be a particularly challenging lesion subset. The aim of this study was to analyze the technical aspects and outcomes of aorto-ostial CTO PCI in a multicenter registry. METHODS Patients undergoing aorto-ostial CTO PCI at 4 centers between February 2013 and December 2018 were included. Success rates, as well as procedural aspects and outcomes, were analyzed. RESULTS A total of 103 patients were included. Mean age was 64±10 years and the mean J-CTO score was 3.1±1.1. Thirty-one lesions (30.4%) were flush ostial CTOs. Technical and procedural success were achieved in 79 (76.7%) and 78 (75.7%) of the patients, respectively. The retrograde approach was the most frequent successful crossing technique (n=49; 62.0%), especially in flush vs nonflush aorto-ostial CTOs (82.6% vs 53.5%; P=.02). The only variable independently associated with technical failure was the absence of interventional collaterals (OR, 12.
