Observational StudyFluid Status After Cardiac Surgery Assessed by Bioelectrical Impedance Vector Analysis and the Effects of Extracorporeal Circulation.
Hydration status after cardiac surgery can be difficult to assess, often requiring invasive measurements. Bioelectrical impedance vector analysis (BIVA) is based on patterns of resistance (R) and reactance (Xc), corrected by height, and has been used in various clinical scenarios to determine body composition and monitor its changes over time. The purpose of the present study was to apply this method in cardiac surgery patients to assess the variation in hydration status and to compare its changes according to the use of extracorporeal circulation. ⋯ Fluid status assessment with BIVA in cardiac surgery showed an increase in total body water up to 24 hours after surgery. Off-pump surgery prevented overhydration, which partially could explain the reduction in some of the postoperative complications. BIVA could serve as a useful method for monitoring fluid status in the setting of goal-directed therapy to assist in maintaining euvolemia in cardiac surgical patients.

Using Machine Learning to Predict Postoperative Liver Dysfunction After Aortic Arch Surgery.
The study compared machine-learning models with traditional logistic regression to predicting liver outcomes after aortic arch surgery. ⋯ The machine-learning method of naïve Bayes predicts PLD after aortic arch surgery significantly better than traditional logistic regression.

CommentCON: The Length of Adult Cardiothoracic Anesthesiology Fellowship Training Should Not Be Extended Beyond One Year.
Fellowship training in adult cardiothoracic anesthesiology (ACTA) is a one-year postgraduate experience with formal accreditation by the Accreditation Council for Graduate Medical Education. ACTA is a competitive and evolving subspeciality. ⋯ The expanding responsibilities of the cardiothoracic anesthesiologist and strategies to best train the future of the subspecialty within the current training structure are discussed. It also briefly examines the history and current status of the fellowship training, reviews considerations for increasing fellowship duration, and highlights personal and financial considerations during the training.
