BACKGROUND: Aortic valve predilation with balloon aortic valvuloplasty (BAV) is recommended before transcatheter aortic valve implantation (TAVI), despite limited data around the requirement of this preprocedural step and the potential risks of embolization. This study aimed to investigate the trends in practice and associations of BAV on short-term outcomes in the UK TAVI registry. METHODS AND RESULTS: Eleven clinical endpoints were investigated, including 30-day mortality, myocardial infarction, aortic regurgitation, valve dysfunction, and composite early safety...

OBJECTIVE: Endovenous heat-induced thrombosis (EHIT) is a well-documented phenomenon that follows endovenous ablation, but the treatment, surveillance, and risk factors for EHIT have yet to be comprehensively elucidated. We sought to identify characteristics that may put patients at higher risk for development of EHIT after radiofrequency ablation (RFA) for the treatment of symptomatic superficial venous insufficiency. METHODS: A retrospective review was performed of all consecutive patients undergoing treatment with RFA to the great saphenous vein by a single surgeon from July 2013 through October 2015...

The optimal decision regarding whether to repair or replace the tricuspid valve (TV) remains controversial in patients with very severe functional tricuspid regurgitation (TR). We sought to compare clinical outcomes of TV repair versus replacement for very severe TR associated with severe TV tethering. We included 96 consecutive patients (20 men, 58 ± 11 years of age) who had both severe tethering of TV and very severe functional TR and consequently underwent TV surgery during left-sided valve surgery. TV repair was performed on 79 patients (repair group), whereas 17 patients underwent TV replacement (replacement group)...

PURPOSE: Recently, single-incision thoracoscopic surgery (SITS) has been recognized as a favorable treatment choice for primary spontaneous pneumothorax (PSP) compared with conventional three-port video-assisted thoracoscopic surgery (VATS). However, conventional SITS bullectomy often results in collisions with surgical devices. Therefore, we devised a method of SITS using a chest wall pulley for lung excision (PulLE) and modified PulLE (mPulLE) system, which substitutes threads to eliminate such collisions...

BACKGROUND AND AIMS: Carvedilol, a non-selective beta-blocker (NSBB) with additional anti-alpha 1 receptor activity, is a potent portal hypotensive agent. It has been used as prophylaxis against variceal bleed. However, its safety in decompensated liver cirrhosis with ascites is still disputed. In this study, we examined whether long-term use of carvedilol in the presence of ascites is a risk factor for mortality. METHODS: This was a single-centre retrospective analysis of 325 consecutive patients with liver cirrhosis and ascites presenting to our Liver Unit between 1(st) of January 2009 to 31(st) August 2012...

Filament formation is a common bacterial defense mechanism and possibly has a broad impact on microbial community dynamics. In order to examine the impact of filament formation on population dynamics, we developed an experimental system with a filamentous bacterium Flectobacillus sp. MWH38 and a ciliate predator Tetrahymena pyriformis. In this system, the effective defense of Flectobacillus resulted in the extinction of Tetrahymena by allowing almost no population growth. The result of a kairomone experiment suggested the existence of chemical signals for filament formation...

BACKGROUND: Hepatic epithelioid hemangioendothelioma (HEHE) is a rare vascular tumor which has an intermediate aggressive behavior. Although the value of liver transplantation (LT) is well established, its place in the management of HEHE is still unclear. The aim of this study is to confirm, based on a very large patient cohort, the value of LT in the management of HEHE and to identify risk factors for post-LT recurrence. METHODS: The outcome of 149 transplant recipients with HEHE recorded in the European Liver Transplant Registry during the period November 1984 to May 2014 was analyzed...

Background. A single dose of perioperative dexamethasone (8-10 mg) reportedly decreases postoperative nausea, vomiting, and pain but has not been widely used in laparoscopic donor nephrectomy (LDN). Methods. We performed a retrospective cohort study of living donors who underwent LDN between 2013 and 2015. Donors who received a lower dose (4-6 mg)  (n = 70) or a higher dose (8-14 mg) of dexamethasone (n = 100) were compared with 111 donors who did not receive dexamethasone (control). Outcomes and incidence of postoperative nausea, vomiting, and pain within 24 h after LDN were compared before and after propensity-score matching...

Whether or not esophagogastric varices (EGV) could determine the outcomes of patients with hepatocellular carcinoma (HCC) is still unclear. A total of 990 treatment-naive HCC patients who received an esophagogastroduodenoscopy at the time of HCC diagnosis were retrospectively enrolled. The factors in terms of prognosis were analyzed by Cox proportional hazards model and propensity score matching analysis. Among the enrolled patients, 480 (48.5%) patients had EGV. Patients with EGV had a significantly lower cumulative 5-year survival rate than those without EGV (24...

A multiparametric sequence-specific model for predicting peptide electrophoretic mobility has been developed using large-scale bottom-up proteomic CE-MS data (5% (∼0.8M) acetic acid as background electrolyte). Peptide charge (Z) and size (molecular mass, M) are the two major factors determining electrophoretic mobility, in complete agreement with previous studies. The extended size of the data set (>4000 peptides) permits access to many sequence-specific factors that impact peptide mobility. The presence of acidic residues Asp and Glu near the peptide N-terminus is by far the most prominent among them...

BACKGROUND: Comorbidity has a great impact on lung cancer survival. Renal function status may affect treatment decisions and drug toxicity. The survival outcome in lung cancer patients with coexisting chronic kidney disease (CKD) has not been fully evaluated. We hypothesized that CKD is an independent risk factor for mortality in patients with lung cancer. METHODS: A retrospective, propensity-matched study of 434 patients diagnosed between June 2004 and May 2012 was conducted...
