This study assesses differences in biological and behavioral domains that relate to individual adaptation and resiliency to an isolated, confined and controlled environment, and evaluates the effect of confinement, work, monotony, and social and physical isolation on stress resiliency and well-being.
In the nutrition guideline (A.S.P.E.N guideline), there was no recommendation about the feeding type in enteral feeding of critically ill patients. Continuous feeding is the most popular feeding type in ICU because of its less nursing burden and reducing the aspiration incidence theoretically. However, some previous studies demonstrated that there were no complications differences between continuous and time-restricted feedings（such as intermittent feedings）. In ICU,...
WATCH-Rhythm is a prospective, randomized, multi-center, investigation to collect safety and effectiveness data on combining conventional AF ablation with LAA electric isolation and closure within a single procedure.
Cholesterol is the precursor of glucocorticoids, mineralocorticoids and sex steroids. Both adrenal and non-adrenal (ovarian + testicular) all steroid hormones are primarily synthesized using the LDL–cholesterol in the circulation. Additionally there is ‘de novo’ cholesterol synthesis in both the adrenals and gonads controlled by the HMG-CoA reductase enzyme. A third pathway is the use of circulatory HDL–cholesterol by the adrenal and gonadal tissues for the synthesis of...
Objective: This prospective study aims to examine the outcome of atrial fibrillation (AF) ablation after permanent pulmonary vein antrum isolation or pulmonary vein antrum isolation plus left atrial posterior wall isolation is proven by a repeat procedure. The study will be conducted in patients with different types of AF: paroxysmal AF (PAF) and non-PAF (Persistent AF and Long Standing Persistent AF). Hypothesis: In addition to permanent pulmonary vein antrum isolation, prove...
The investigators prospectively investigate the differences between contact-force guided pulmonary vein isolation (PVI) and conventional pulmonary vein isolation in patients with paroxysmal atrial fibrillation (PAF) with respect to adenosine guided unmasking of dormant conduction, procedural and clinical outcome.
Pulmonary vein (PV) isolation is very important in atrial fibrillation (AF) catheter ablation. PV reconnection is one of the main reasons in AF recurrence. Contact force-sensing catheter is a new catheter which has valuable tools to monitor and increase the efficacy of PV isolation. Previous paper reported the efficacy of contact force-sensing catheter on immediate PV isolation and outcome. However, there might be confounding factor as inter-individual variation. Therefore, we ...
The purpose of this split-mouth, randomized, controlled trial is to evaluate the retention rates of sealants placed under Isolite vs. cotton roll isolation. This study will also compare the patient and operator acceptability and satisfaction of the two isolation techniques as well as the time consumed for sealant application during the two isolation techniques.
We conduct a randomized study comparing the safety and effectiveness of two interventional ablation techniques for treatment of paroxysmal atrial fibrillation: the segmental pulmonary vein ablation approach, (1) with empiric isolation of all pulmonary veins or (2) Segmental Isolation of the arrhythmogenic pulmonary vein(s)
Comparison of Circumferential Pulmonary Vein Isolation Alone Versus Linear Ablation in Addition to Circumferential Pulmonary Vein Isolation for Catheter Ablation in Persistent Atrial Fibrillation: Prospective Randomized Controlled Trial
The purpose of this study is to compare the clinical outcomes depending on catheter ablation strategy for persistent atrial fibrillation. After randomization, investigators will conduct circumferential pulmonary vein isolation alone in a group, and additional posterior box isolation and anterior linear ablation in the other group. Investigators will compare clinical recurrence rate, complication rate, and procedure time, etc.
The purpose of this study is to compare the efficacy and safety of PV isolation with continued antiarrhythmic drug treatment (PVI+ADT) to PV isolation without continued ADT (PVI-ADT) in patients undergoing treatment for symptomatic recurrent AF.
Cryoballoon ablation is proven to be effective in pulmonary vein isolation in patients with paroxysmal atrial fibrillation. However, it is not certain that cryoablation is effective and safe in patients with persistent atrial fibrillation, because of higher chance of recurrence compared to paroxysmal atrial fibrillation. The aim of this study is to evaluate the efficacy and safety of cryoballoon pulmonary vein isolation vs. cryoballoon pulmonary vein isolation with additional r...
The purpose of this study is to evaluate and compare the clinical retention of bonded fissure sealants placed under rubber dam isolation and cotton roll isolation.
The present study is designed as a observational prospective, multicentre, international. The main aim of this study is to evaluate the safety and feasibility of SVC isolation with the CB in a prospective manner.
The purpose of this study is to investigate the significance of complete versus incomplete electrical isolation of pulmonary veins by radiofrequency-induced linear lesions in patients with paroxysmal atrial fibrillation. The study hypothesis ist that the complete linear PV isolation ablation is superior to the non-complete linear PV isolation on the outcome of patients with idiopathic drug-refractory atrial fibrillation. As a second hypothesis in this adaptive study design, th...
Collagen synthesis is depressed systemically in the immediate postoperative period. Arginine, zinc and vitamin C impact collagen synthesis. The aim of this study is to investigate the effect of a pre and postoperative oral supplement consisting of arginine, zinc and vitamin C on collagen synthesis in patients undergoing inguinal hernia repair.

The purpose of this study is to compare the clinical outcomes depending on catheter ablation strategy for repeat ablation procedure among the patients with recurred atrial fibrillation after de novo catheter ablation. After randomization, we will conduct circumferential pulmonary vein isolation alone in a group, and additional posterior box isolation and anterior linear ablation in the other group. Non-pulmonary vein foci ablation will be done in all patients. We will compare c...
A three-pronged approach to evaluate long term success of non-paroxysmal ablation when using a: 1. specified low voltage-directed with pulmonary vein isolation (LD+PVI) approach compared to , 2. empiric posterior wall isolation with pulmonary vein isolation (PW+PVI) approach compared to 3. an approach of pulmonary vein isolation (PVI) alone.
The chronic success rate, defined as freedom from any atrial tachyarrhythmias will increase from 35% to 60% by ablation of complex fragmented atrial electrograms potentials in addition to pulmonary vein isolation (PVI) as compared to PVI alone in patients with long-standing persistent AF.
Social isolation among elderly people is a frequent and major determinant for health. The risk of premature death is 2 to 5 time higher for socially isolated people, similarly for morbidity, duration of healing and complications rate. Denutrition is also frequent for elderly people with potentially serious consequences. Vitamin deficiency, especially in B9 and B12 vitamins, are often associated with denutrition among elderly people. Folic acid (vitamin B9) is not influ...
Investigator initiated, randomized controlled trial of two radiofrequency (RF)ablation protocols currently performed in the electrophysiology lab, but have not been studied prospectively to identify which, if either technique, is superior for individuals with persistent atrial fibrillation (AF). Two-hundred subjects will be consecutively enrolled and randomized to either pulmonary vein isolation only or pulmonary vein isolation plus posterior left atrial wall isolation
The aim of the present study is to investigate the effect of added protein+leucine or caffeine to 1.2 g/kg/h CHO on the rate of post-exercise muscle glycogen re-synthesis in healthy, recreational athletes. The investigators hypothesize that both interventions (the addition of caffeine or protein+leucine) will lead to higher glycogen re-synthesis compared to the ingestion of CHO only, and that the co-ingestion of protein and leucine will result in the highest muscle glyco...
