Impact of primary organ site of involvement by peripheral T-cell lymphoma not otherwise specified on survival.

Introduction: Peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) is a rare, highly heterogeneous group of mature T-cell neoplasms that historically has been associated with poor outcomes. We sought to investigate the influence of primary disease site on PTCL-NOS outcomes using a large national cancer registry.

Methods: Baseline clinical and demographic data including primary organ of involvement and Ann Arbor disease stage were extracted from the SEER database.

Antero-lateral vs. antero-posterior electrode position for cardioversion of atrial fibrillation: a systematic review and meta-analysis of randomized controlled trials.

Background: Multiple randomized controlled trials (RCTs) have compared the success of antero-lateral vs. antero-posterior electrode position for cardioversion of atrial fibrillation (AF). However, due to small sample size and conflicting results of these RCTs, the optimal electrode positioning for successful cardioversion remains uncertain.
