The Association of the Pulmonary Artery Pulsatility Index and Right Ventricular Function after Cardiac Surgery.

Background: The pulmonary artery pulsatility index (PAPi) has been shown to correlate with right ventricular (RV) failure in patients with cardiac disease. However, the association of PAPi with right ventricular function following cardiac surgery is not yet established.

Methods: PAPi and other hemodynamic variables were obtained postoperatively for 959 adult patients undergoing cardiac surgery.

Postoperative Pulmonary Artery Pulsatility Index Improves Prediction of Right Ventricular Failure After Left Ventricular Assist Device Implantation.

Objectives: This study evaluated whether the postoperative pulmonary artery pulsatility index (PAPi) is associated with postoperative right ventricular dysfunction after durable left ventricular assist device (LVAD) implantation.

Design: Single-center retrospective observational cohort study.

Setting: The University of Kansas Medical Center, a tertiary-care academic medical center.

Evaluating the causal impact of individual alcohol licensing decisions on local health and crime using natural experiments with synthetic controls.

Background And Aims: Given the costs of alcohol to society, it is important to evaluate whether local alcohol licensing decisions can mitigate the effects of alcohol misuse. Robust natural experiment evaluations of the impact of individual licensing decisions could potentially inform and improve local decision-making. We aimed to assess whether alcohol licensing decisions could be evaluated at small spatial scale by using a causal inference framework.
