Comparison of Early Versus Delayed Initiation of Vasopressin in Post-Cardiothoracic Surgery Vasoplegic Shock and the Effect on Post-Operative Atrial Fibrillation.

Post-operative complications of cardiothoracic surgery include vasoplegic shock and post-operative atrial fibrillation (POAF). Use of catecholamines for vasoplegic shock may enhance the risk of POAF; thus, use of non-catecholamine vasopressors is reasonable. This retrospective, single-center cohort study compared early to delayed initiation of vasopressin in vasoplegic shock and assessed the association with POAF.

Buckypaper-Bilirubin Oxidase Biointerface for Electrocatalytic Applications: Buckypaper Thickness.

Electrode materials play an important role on the electrocatalytic properties of immobilized biocatalysts. In this regard, achieving direct electronic communication between the electrode and redox sites of biocatalysts eliminates the need for additional electron transfer mediators for biocatalytic applications in fuel cells and other electrochemical energy devices. In order to increase electrocatalytic currents and power in fuel cells and metal-air batteries, conductive carbon-nanostructure-modified large surface area electrodes are quite useful.
