Prebypass Critical Closing Pressure Predicts Acute Kidney Injury After Cardiopulmonary Bypass.

Objectives: Optimal blood pressure goals during cardiopulmonary bypass (CPB) remain uncertain and new metrics to individualize perfusion targets are needed. Critical closing pressure (Pcrit) is a fundamental property of the arterial circulation related to vascular tone and represents the outflow pressure impacting flow across the systemic circulation. We examined Pcrit as a prognostic marker of acute kidney injury (AKI).

Robotic right ventricle is a biohybrid platform that simulates right ventricular function in (patho)physiological conditions and intervention.

The increasing recognition of the right ventricle (RV) necessitates the development of RV-focused interventions, devices and testbeds. In this study, we developed a soft robotic model of the right heart that accurately mimics RV biomechanics and hemodynamics, including free wall, septal and valve motion. This model uses a biohybrid approach, combining a chemically treated endocardial scaffold with a soft robotic synthetic myocardium.

Assessing the acceptability of a culturally adapted group-based pediatric intervention, Kokajjiriri, for Marshallese mothers and infants to improve nutrition and prevent childhood obesity.

Background: Marshallese Pacific Islanders experience higher rates of obesity than other racial and/or ethnic communities. Despite the obesity rates experienced in this community, there are currently no childhood obesity prevention interventions designed for Marshallese Pacific Islanders in the United States. The purpose of this study is to assess the acceptability and feasibility of a culturally adapted group-based pediatric intervention, Kokajjiriri, with Marshallese mothers to improve nutrition and reduce childhood obesity.
