Is cryoballoon ablation preferable to radiofrequency ablation for treatment of atrial fibrillation by pulmonary vein isolation? A meta-analysis.

PLoS ONE, 2014
ObjectiveCurrently radiofrequency and cryoballoon ablations are the two standard ablation systems used for catheter ablation of atrial fibrillation; however, there is no universal consensus on which ablation is the optimal choice.

Surgical Outcomes and Recurrence Management in Borderline Resectable Hepatocellular Carcinoma: Implications for Multidisciplinary Strategies

Annals of Gastroenterological Surgery, EarlyView.
Multivariate analysis identified that up‐to‐7 out (p < 0.001), lymph node metastasis (p < 0.001), and non‐anatomical resection (p = 0.02) were independent predictors of cancer recurrence, while older age (p = 0.01), Child‐Pugh B (p < 0.001), up‐to‐7 out (p = 0.01), macrovascular invasion (p = 0.01), and lymph node metastasis (p < 0.001) were ...
