Article Synopsis
  • Atrial tachyarrhythmia (ATA) recurrence is common after pulmonary vein isolation (PVI) in patients with persistent atrial fibrillation (PsAF), with a study showing a 79.7% freedom rate from ATA after 12 months.
  • Long intervals between PsAF diagnosis and ablation, as well as multiple prior unsuccessful treatments, are significant predictors of ATA recurrence following cryoballoon ablation (CBA).
  • The findings emphasize the importance of timely referral for treatment to potentially improve outcomes for PsAF patients undergoing CBA.

Until now, Hippo pathway-mediated nucleocytoplasmic translocation has been considered the primary mechanism by which yes-associated protein (YAP) and transcriptional co-activator with PDZ-binding motif (TAZ) transcriptional coactivators regulate cell proliferation and differentiation via transcriptional enhanced associate domain (TEAD)-mediated target gene expression. In this study, however, we found that TAZ, but not YAP, is associated with the Golgi apparatus in macrophages activated via Toll-like receptor ligands during the resolution phase of inflammation. Golgi-associated TAZ enhanced vesicle trafficking and secretion of proinflammatory cytokines in M1 macrophage independent of the Hippo pathway.

Background And Aims: Early rhythm-control therapy in atrial fibrillation (AF) results in higher freedom from atrial arrhythmia (AA) recurrence and improved cardiovascular outcomes. The optimal timing of Cryoballoon ablation (CBA) is unknown.

Methods: We evaluated AA recurrence and procedure-related complications of early vs.

Despite advances in gastric cancer diagnosis and treatment, its prognosis remains poor owing to aggressive tumor progression and metastasis. As understanding the relevant molecular mechanisms is essential to effectively improve patient outcomes, we elucidated the role of Kindlin-1 in gastric cancer progression and metastasis. Kindlin-1 expression was analyzed in 359 gastric cancer tissue samples provided by Kangnam Sacred Heart Hospital and publicly available GSE datasets.
