Cryoballoon Pulmonary Vein Isolation With Versus Without Additional Right Atrial Linear Ablation for Persistent Atrial Fibrillation: The CRALAL Randomized Clinical Trial.

Background: Pulmonary vein isolation (PVI) alone is less effective in patients with persistent atrial fibrillation (AF) compared with those with paroxysmal AF. We investigate whether additional linear ablation from the superior vena cava to the right atrial septum and cavotricuspid isthmus ablation improves the rhythm outcome of patients with persistent AF undergoing cryoballoon PVI (Cryo-PVI).

Methods: In this investigator-initiated, multicenter, randomized clinical trial, 289 patients with persistent AF refractory to antiarrhythmic drug therapy were randomized 1:1 to either Cryo-PVI with additional right atrium (RA) linear ablation or Cryo-PVI alone.

Meta-analysis of Intravascular Ultrasound-guided versus Angiography-guided Endovascular Treatment in Lower Extremity Artery Disease.

Intravascular ultrasound (IVUS) offers precise information about lesion morphology and enhance the optimization of endovascular treatments (EVT). Nevertheless, the impact of IVUS on the durability of EVTs and clinical outcomes remains uncertain. The aim of this systematic review and meta-analysis was to evaluate the efficacy of IVUS-guided EVT compared with angiography-guided EVT.

Methods And Results: This study was based on the multi-centre inherited arrhythmia syndrome registry in South Korea from 2014 to 2017.

Clinical and Genetic Features of Korean Inherited Arrhythmia Probands.

Background And Objectives: Inherited arrhythmia (IA) is a more common cause of sudden cardiac death in Asian population, but little is known about the genetic background of Asian IA probands. We aimed to investigate the clinical characteristics and analyze the genetic underpinnings of IA in a Korean cohort.

Methods: This study was conducted in a multicenter cohort of the Korean IA Registry from 2014 to 2017.

Developing and Testing a Model of Dynamic Changes in Work-School Conflict and Workplace Deviance Over Time.

Work-school conflict is a major stressor for many college students who have paid jobs while in college. Although work-school conflict experience is dynamic, the extant research has predominantly cast it and its consequences as between-person phenomena from a static perspective, ignoring its inherent temporal nature. As a result, little is known about the intra-individual changes in work-school conflict and their associated consequences as implied by the related theory.

Faking at work, struggling to be healthy at home: A model of surface acting and its relation with unhealthy eating and physical activity.

Performing emotional labor impairs mood as well as regulatory control of employees, and we compare these mechanisms to explain critical health-related behaviors: eating and exercise. Two studies examine the relationship of surface acting at work with unhealthy eating and physical activity at home as mediated by negative and positive affect. Emotion regulation (ER) self-efficacy is tested as a moderator of the indirect relationships.

Treat me better, but is it really better? Applying a resource perspective to understanding leader-member exchange (LMX), LMX differentiation, and work stress.

The leader-member exchange (LMX) literature proposes that leaders tend to differentiate the quality of relationships among their followers, but it remains unclear how individual LMX and LMX differentiation (i.e., the degree to which followers' LMX quality with the same leader varies within a team) may jointly shape follower well-being such as work stress.

Because I know how it hurts: Employee bystander intervention in customer sexual harassment through empathy and its moderating factors.

Customer sexual harassment (CSH) is a persistent problem that harms worker well-being in many service industries. In turn, bystander intervention in the workplace is critical for preventing and stopping customers' inappropriate behaviors as well as mitigating the detrimental effects of such harassment on workers. However, previous research has rarely examined what can facilitate bystander employees' intervention behaviors in CSH incidents.

Time to Disentangle the Information and Communication Technology (ICT) Constructs: Developing a Taxonomy around ICT Use for Occupational Health Research.

The use of information and communication technology (ICT) in the workplace has gained considerable research attention in the occupational health field due to its effects on employee stress and well-being. Consequently, new ICT-related constructs have proliferated in occupational health research, resulting in a need to take stock of both potential redundancies and deficiencies in the current measures. This paper disentangles ICT-related constructs, developing a taxonomy of ICT-related constructs in terms of ICT demands, resources, motivation, use, and strains.

Daily microbreaks in a self-regulatory resources lens: Perceived health climate as a contextual moderator via microbreak autonomy.

Grounded in self-regulatory resources and conservation of resources theories, the current research examines poor self-regulatory capacity as a precursor to microbreaks and their possible outcomes at work. Full-time employees completed multiple online surveys for 10 ( = 779 daily observations) and 5 workdays ( = 1,024 daily observations). In Study 1, multilevel path analysis results showed that on days when employees had poorer recovery at home (i.

Uniform-thickness electrospun nanofiber mat production system based on real-time thickness measurement.

Electrospinning is a simple versatile process used to produce nanofibers and collect them as a nanofiber mat. However, due to bending instability, electrospinning often produces a nanofiber mat with non-uniform mat thickness. In this study, we developed a uniform-thickness electrospun nanofiber mat (UTEN) production system with a movable collector based on real-time thickness measurement and thickness feedback control.

Cardiovascular outcomes with glucagon-like peptide 1 agonists and sodium-glucose cotransporter 2 inhibitors in patients with type 2 diabetes: A meta-analysis.

Background: According to available research, there have been no head-to-head studies comparing the effect of glucagon-like peptide 1 (GLP-1) agonists and sodium-glucose cotransporter 2 (SGLT-2) inhibitors on cardiovascular outcomes among patients with type 2 diabetes not reaching glycemic goal with metformin.

Methods: Relevant studies were identified through electronic searches of PubMed and EMBASE published up to January 15, 2020. Efficacy outcomes of interest included the composite of cardiovascular death, non-fatal myocardial infarction, or non-fatal stroke, its individual components, all-cause death, and hospitalization for heart failure (HF).

Put you down versus tune you out: Further understanding active and passive e-mail incivility.

Although e-mail incivility is becoming a growing concern in the workplace, it remains an understudied topic. Scholars have paid inadequate attention to its dimensionality (i.e.

Development of a Lidocaine-Loaded Alginate/CMC/PEO Electrospun Nanofiber Film and Application as an Anti-Adhesion Barrier.

Surgery, particularly open surgery, is known to cause tissue/organ adhesion during healing. These adhesions occur through contact between the surgical treatment site and other organ, bone, or abdominal sites. Fibrous bands can form in unnecessary contact areas and cause various complications.

How to benefit from weekend physical activities: Moderating roles of psychological recovery experiences and sleep.

This study examines the short-term recovery benefits of weekend physical activity on reduced negative affective state (NA) on Monday morning, using a weekly diary method from 70 employees across four weekends (repeated pre- and post-weekend measures). The first hypothesis tests the within-person relationship between weekend physical activity and post-weekend NA. The results of multilevel path analysis show that the main effect of weekend physical activity on reduced Monday NA is not significant.

Customer mistreatment harms nightly sleep and next-morning recovery: Job control and recovery self-efficacy as cross-level moderators.

Customer mistreatment is becoming an important topic for work stress researchers and practitioners given the rise of service industry. Taking stressor-emotion-control perspectives, the authors examine day-level relationships between call center workers' customer mistreatment experiences and their impaired recovery outcomes mediated by end-of-work negative affect. Furthermore, control concepts in the job and personal domains are tested as cross-level moderators.

Daily micro-breaks and job performance: General work engagement as a cross-level moderator.

Despite the growing research on work recovery and its well-being outcomes, surprisingly little attention has been paid to at-work recovery and its job performance outcomes. The current study extends the work recovery literature by examining day-level relationships between prototypical microbreaks and job performance as mediated by state positive affect. Furthermore, general work engagement is tested as a cross-level moderator weakening the indirect effects of microbreaks on job performance via positive affect.

Which patients recur as atrial tachycardia rather than atrial fibrillation after catheter ablation of atrial fibrillation?

Introduction: The ablation gaps have been known as the main mechanism of recurrence as atrial tachycardia (AT) rather than atrial fibrillation (AF) after AF catheter ablation. However, AF organization due to reduction of critical mass or focal trigger may also be the mechanism of AT recurrence. We sought to find out the main clinical factors of recurrence as AT rather than AF after AF ablation in the absence of antiarrhythmic drug effect.

Associates and Prognosis of Giant Left Atrium; Single Center Experience.

Background: Left atrial (LA) remodeling develops as a result of longstanding pressure overload. However, determinants and clinical outcome of excessive remodeling, so called giant left atrium (GLA), are not clear.

Methods: Clinical characteristics of patients with GLA (antero-posterior diameter higher than 65 mm), including echo-Doppler parameters, and follow-up clinical outcomes from a tertiary referral hospital were investigated.

Controlled Atrial Fibrillation after Pulmonary Vein Stenting.

When there is no pulmonary vein reconnection after catheter ablation for atrial fibrillation, patients can experience recurrence of atrial fibrillation without clear evidence of non-pulmonary vein foci. We describe a patient with significant pulmonary vein stenosis and recurrent atrial fibrillation after four ablation procedures. After successful pulmonary vein stenting, the symptoms were resolved, and sinus rhythm was maintained for 2 years without treatment with antiarrhythmic medication.

Comparison of the Antiplatelet Effects of Once and Twice Daily Low-Dose Ticagrelor and Clopidogrel After Percutaneous Coronary Intervention.

Although Asian people are believed to be more susceptible to bleeding on currently recommended dose of ticagrelor, there is limited evidence supporting low-dose ticagrelor. We prospectively randomized patients receiving dual antiplatelet therapy with aspirin and clopidogrel into 3 groups; aspirin plus clopidogrel 75 mg versus aspirin plus ticagrelor 90 mg once daily versus aspirin plus ticagrelor 45 mg twice daily. Platelet function assessments were conducted using VerifyNow P2Y12 assay at baseline and 28 days after randomization.

Anticoagulation therapy in atrial fibrillation after intracranial hemorrhage.

Background: The effect of oral anticoagulation therapy (OAT) in patients with atrial fibrillation (AF) with a history of intracranial hemorrhage (ICH) is poorly defined.

Objective: The purpose of this study was to evaluate the efficacy and safety of OAT in patients with AF with an ICH history.

Methods: We retrospectively compared the composite end point, including thromboembolic and major bleeding events, between patients with AF with a history of ICH who were (OAT group, n = 254) and those who were not (no-OAT group, n = 174) taking OAT.

Dual-earner couples' weekend recovery support, state of recovery, and work engagement: Work-linked relationship as a moderator.

Despite growing recovery research, little is known about couple-dyadic processes of recovery from work. Given that dual-earner couples experience most of their recovery opportunities during nonwork times when they are together, partners in a couple relationship may substantially affect recovery and work engagement. In this study, we propose a couple-dyadic model in which weekend partner recovery support (reported by the recipient partner) is positively related to the recipient partner's state of recovery after the weekend which, in turn, increases the recipient's work engagement the following week (actor-actor mediation effect).
