Solid-state NMR spectra identified rigid parts of the FapC fibril. We assigned Cα-Cβ chemical shifts, indicative of a predominant β-sheet topology with some α-helix or loop chemical shifts. Our work emphasizes the complex nature of FapC fibrillation. In addition, we are able to deduce the importance of non-repeat regions (i.e., predicted loops), which enhance the amyloid protein aggregation and their influence on the polymorphism of the fibril architecture. OBJECTIVE To define the relationship between urology RVUs and measures of surgical complexity and physician workload. Secondary objectives include 1) identifying procedures with outlying RVU values for their measures of surgical complexity and workload; and 2) calculating projected RVU values for these procedures. METHODS We obtained surgical case data for 71 urology current procedural terminology (CPT) codes from the 2017 American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database. Pearson correlation coefficients were calculated to measure the association between mean total work RVU (mRVU) and operative time, length of hospital stay (LOS), serious adverse events (SAEs), readmissions, and mortality. We developed a multivariable regression model to predict mRVU from these measures. Studentized residuals were used to identify outlying CPT codes for both bivariable and multivariable regression models, and empirically derived RVU values from complexity and work effort metrics were estimated. RESULTS We analyzed 71 urology CPT codes encompassing 55,068 cases. RVUs correlated well with median LOS (R = 0.81), median operative time (R = 0.92), SAEs (R = 0.83), and readmissions (R = 0.74). RVUs were poorly correlated with mortality (R = 0.34). Outlying procedures identified using the multivariable model were retroperitoneal lymph node dissection (projected +21.09 RVUs), laparoscopic ureteroneocystotomy (projected -12.34 RVUs), and cystectomy with bilateral pelvic lymphadenectomy (projected +9.37 RVUs). CONCLUSION Urology work RVUs correlate more with operative time than other measures of surgical complexity and physician workload. There exist several significant outlying procedures for various work measures. Incorporating objective work data may improve RVU assignments in the future. OBJECTIVE To assess the effects of robot-assisted radical prostatectomy in the Trendelenburg position on postoperative neurocognitive outcomes this study compared cognitive function between patients who underwent robot-assisted radical prostatectomy and those who underwent open retropubic radical prostatectomy. METHODS Objective evaluations of pre- and postoperative cognitive function were performed upon admission and before hospital discharge, by using a neuropsychological test battery. We collected self-reported data on cognitive failures at 3 months postoperatively. Binary logistic regression analysis was used to assess the effects of surgical technique on postoperative cognitive performance. RESULTS The pre- and postoperative neuropsychological assessments were completed by 367 patients with a median age of 64 years (range 44-76). The incidence of postoperative cognitive dysfunction was 23.9% after robot-assisted (39/165) and 22.3% after open radical prostatectomy (45/202). There was no significant difference in postoperative cognitive function during the early postoperative period (p=0.758) and self-reported cognitive failures at 3 months (p=0.303) between robot-assisted and open surgery. Surgical technique was not associated with early postoperative cognitive dysfunction in multivariable analysis (OR 1.012, 95% CI 0.608-1.685, p=0.962). CONCLUSION Compared with open surgery in supine position postoperative neurocognitive disorders do not occur more frequently after robot-assisted radical prostatectomy in the extreme Trendelenburg position. Based on these findings potential adverse effects on cognitive function do not have to be considered in the choice of surgical approach for radical prostatectomy. BACKGROUND AND AIMS EUS guided biliary drainage is indicated in case of impossibility or failure of classic biliary drainage by ERCP. Recently we reported a good efficiency of EUS-guided choledocoduodenostomy (EUS-CDS) using the ECE-LAMS (electrocautery-enhanced lumen-apposing metal stent) in a retrospective multicentric study. Utilization of the recommended technique (direct punction with the ECE-LAMS using a pure cut current + using a 6 mm stent) was the only predicting factor of clinical success. We reevaluated this procedure after 1 year in the same centers. METHODS This was a French retrospective multicentric study of a prospective database including all cases of EUS-guided CDS with ECE-LAMS in the 7 centers that participate in the first study. RESULTS Seventy consecutive patients were included in this study between September 1, 2017 and September 22, 2018. Failure of primary ERCP was due to duodenal stenosis in 44% of cases, tumoral infiltration of the papilla in 22% of cases. The mean duration of the procedure was 5 minutes (±3). The recommended technique was used in 98.5% of cases. selleck inhibitor The technical and clinical success rate were both 97.1% (69/70). Short-term adverse events (perprocedural + intrahospital) occurred in 1.6%. CONCLUSIONS EUS-CDS with the ECE-LAMS is efficacious and safe in distal malignant obstruction of the common bile duct in cases of ERCP failure with impressive results once the expertise is acquired and the recommended technic (direct fistulotomy, pure cut current, and 6 mm stent) is followed. BACKGROUND AND AIMS Protruding lesions of the small bowel vary in wireless capsule endoscopy (WCE) images, and their automatic detection may be difficult. We aimed to develop and test a deep learning-based system to automatically detect protruding lesions of various types in WCE images. METHODS We trained a deep convolutional neural network (CNN), using 30,584 WCE images of protruding lesions from 292 patients. We evaluated CNN performance by calculating the area under the receiver operating characteristic curve (AUC), sensitivity, and specificity, using an independent set of 17,507 test images from 93 patients, including 7,507 images of protruding lesions from 73 patients. RESULTS The developed CNN analyzed 17,507 images in 530.462 seconds. The AUC for detection of protruding lesions was 0.911 (95% confidence interval [Cl], 0.9069 - 0.9155). The sensitivity and specificity of the CNN were 90.7% (95% CI, 90.0% - 91.4%) and 79.8% (95% CI, 79.0% - 80.6%), respectively, at the optimal cut-off value of 0.317 for probability score.
