Aim: To compare the overall survival (OS) in patients without recurrent hepatocellular carcinoma (HCC) after initial radiofrequency ablation (RFA) and in those with recurrence, treated with repeat-RFA.
Patients And Methods: We compared OS between patients without recurrence (group A; n=150) and those with recurrence treated with repeat-RFA (group B; n=130).
Results: One-, 3- and 5-year OS after initial RFA was 92.6%, 84.1% and 81.0%, respectively, in group A, and 99.0%, 84.1% and 61.8% in group B (p=0.296). There was no significant difference in OS between group A patients and patients with a single recurrent HCC (p=0.834). On multivariate analysis, serum albumin >3.5 g/dl and first HCC recurrence, comprising of two or three nodules were significant predicting factors of poorer OS.
Conclusion: Even if HCC recurs after initial RFA, survival comparable to that of patients without recurrence can be achieved in patients with a single recurrent tumor treated with repeat-RFA.

Sc-doped GeTe thin films prepared by radio-frequency magnetron sputtering.
Sci Rep
January 2025
Department of Graphic Arts and Photophysics, Faculty of Chemical Technology, University of Pardubice, Studentská 573, Pardubice, 532 10, Czech Republic.
Radio frequency magnetron co-sputtering method employing GeTe and Sc targets was exploited for the deposition of Sc doped GeTe thin films. Different characterization techniques (scanning electron microscopy with energy-dispersive X-ray analysis, X-ray diffraction, atomic force microscopy, sheet resistance temperature-dependent measurements, variable angle spectroscopic ellipsometry, and laser ablation time-of-flight mass spectrometry) were used to evaluate the properties of as-deposited (amorphous) and annealed (crystalline) Ge-Te-Sc thin films. Prepared amorphous thin films have GeTe, GeTeSc, GeTeSc, GeTeSc and GeTeSc chemical composition.

Research Department, Valley Vein Health Center, Turlock, CA, USA.
Purpose: Determine the rate of incidence, risk factors, and management for developing venous thromboembolism (VTE) in patients undergoing radiofrequency ablation (RFA) and ultrasound-guided foam sclerotherapy (UGFS) for varicose veins.
Methods: All charts of patients undergoing venous ablation from 2016 to 2023 were reviewed at a rural vein treatment clinic. The incidence of VTE was noted and a chart review was completed to identify risk factors for VTE, EHIT score, EFIT score, and management.

Department of Internal Medicine and Cardiology, Faculty of Medicine, University Hospital Ostrava, University of Ostrava, 17. listopadu 1790, 708 52 Ostrava, Czech Republic.
Background: Charcot-Marie-Tooth is the most common inherited neuromuscular disorder. Rarely, it can be associated with heart failure and various arrhythmic disturbances. This case illustrates the challenges of making decisions to prevent sudden cardiac death in a patient with Charcot-Marie-Tooth disease.

Background: The success rate of chronic rhinitis surgery varies depending on the patients' factor and surgical method. While outcomes for nasal obstruction differ, the association between preoperative severity of other rhinitis symptoms, such as rhinorrhea, sneezing, and nasal itching, measured via the reflective total nasal symptom score (rTNSS) remains unevaluated.
Objective: To evaluate the association between the response rate to surgical treatment of chronic rhinitis and preoperative severity.
Risk-factor modification to prevent recurrent atrial fibrillation after catheter ablation.

More and more patients with atrial fibrillation are undergoing catheter ablation as a rhythm-control strategy, but the recurrence rate after the procedure is high. A wide array of risk factors contribute to the pathogenesis of atrial fibrillation, including hypertension, diabetes mellitus, dyslipidemia, obesity, obstructive sleep apnea, metabolic dysfunction-associated steatotic liver disease (MASLD), smoking, alcohol consumption, and physical inactivity. This review summarizes the emerging evidence for periablation risk-factor modification to optimize postablation outcomes.
