Article Synopsis
  • This study is a systematic review and meta-analysis that evaluates surgical outcomes from using a harmonic scalpel (HS) versus traditional hemostasis in neck dissection for head and neck cancers.
  • The analysis included 10 randomized control trials with a total of 558 patients and found that the HS method significantly reduced operative time but had a negligible effect on intraoperative blood loss.
  • The research concludes that while HS improves operative efficiency, it does not show advantages in hospital stay length, drain stay length, or postoperative complications compared to conventional methods, indicating the need for further high-quality studies.

Background: Vitamin D insufficiency/deficiency has been identified as a risk factor for postoperative atrial fibrillation (POAF) after coronary artery bypass grafting (CABG). This is associated with significantly increased morbidity and mortality leading to not only prolonged hospital and intensive care unit (ICU) stay, but increased risk of stroke, heart failure, dementia, and long-term atrial fibrillation. This analysis aims to evaluate the efficacy of vitamin D supplementation in preventing POAF in patients undergoing CABG.

Transcatheter aortic valve replacement (TAVR) is a technique that can be performed through multiple approaches, and the benefits of one approach over another are still being evaluated to make sure patients receive the best possible care.
