Hepatocellular carcinoma (HCC) often exhibits a poor prognosis due to metastatic spread caused by portal vein invasion (PVI). In the present study, we attempted to identify a novel therapeutic target related to PVI of HCC. Based on pooled genomic data, we identified RD RNA binding protein (RDBP), a member of the negative elongation factor (NELF) t...

Respiratory variation in the arterial blood pressure and photoplethysmographic (PPG) waveforms have both been shown to predict the haemodynamic response to volume administration. Whether or not the two can be considered interchangeable is controversial. Twenty-three patients undergoing spine surgery received both a 20 gauge intra-arterial catheter and a Masimo adult adhesive SpHb sensor connect...

AIMS Pulmonary vein isolation (PVI) by catheter ablation for atrial fibrillation (AF) requires suppression of patient restlessness by sufficient sedation in addition to maintaining stable respiration. We applied adaptive-servo ventilation (ASV) and examined the effects of ASV combined with deep propofol sedation on PVI using a NavX. METHODS AND RESULTS We analysed 75 paroxysmal AF (PAF) patie...

HYPOTHESIS The anti-infective actions of povidone-iodine (PVI) and sodium hypochlorite enemas are different. DESIGN Prospective, randomized, single-blind study. SETTING Multicenter. PATIENTS Five hundred seventeen consecutive patients with colorectal carcinoma or sigmoid diverticular disease undergoing elective open colorectal resection, followed by primary anastomosis. INTERVENTION All...

BACKGROUND Ablation of persistent atrial fibrillation can be challenging, often involving not only pulmonary vein isolation (PVI) but also additional linear lesions and ablation of complex fractionated electrograms (CFE). We examined the impact of stepwise ablation on a human model of advanced atrial substrate of persistent atrial fibrillation in heart failure. METHODS AND RESULTS In 30 patie...

BACKGROUND The optimal energy setting for endoscopic pulmonary vein (PV) isolation (PVI) has not yet been determined. OBJECTIVE To assess the influence of varying energy settings on the efficacy and safety of endoscopic PVI. METHODS In the current prospective study, 30 patients with paroxysmal atrial fibrillation were consented for PVI using the endoscopic ablation system. Ablation was perf...

Abstract Funding Acknowledgements Type of funding sources: None. Purpose We compared the efficacy, safety, and heart rate variability (HRV) after cryo-balloon (Cryo-PVI), high-power short-duration (HPSD-PVI) or conventional radiofrequency pulmonary vein isolation (conventional-PVI) in patients with atrial fibrillation (AF). Methods In this retrospective analysis single-center cohort, we include...

We describe a new model for the formal representation of the rhythmic tendencies of natural languages. The algorithm is a modification of PVI, proposed by Grabe and Low [10]. The model was tested on a fairly substantial corpus of Italian semispontaneous productions, and its outcome compared with that yielded by two well-known algorithms (Ramus [14] and PVI).

Severe pulmonary vein (PV) stenosis after PV isolation for atrial fibrillation (AF) is a severe complication that requires angioplasty. However, there have been no studies to compare the incidence of among several balloon-type ablations. This study aimed reduction cross-sectional area and cryoballoon (CB)-PVI, hot balloon-PVI (HB), or laser balloon (LB)-PVI. A total 320 patients who underwent a...
