Prediction of Acute Kidney Injury After Cardiac Surgery With Combined Arterial and Venous Intrarenal Doppler.

Background: Acute kidney injury (AKI) occurs in up to 50% of cardiac surgical patients and is often hemodynamically mediated. Point-of-care ultrasound is a non-invasive tool that has the potential to characterize intrarenal hemodynamics and predict the risk of AKI.

Objectives: We aimed to determine the predictive characteristics of intrarenal arterial and venous Doppler markers for postoperative AKI in cardiac surgical patients.

Relationship with Adults in Organized Sports and Non-Sports Activities and Links with Psychological Adjustment in Adolescence: A 6-Year Longitudinal Study.

Relationships with adults in organized activities play a crucial role in the positive outcomes associated with these experiences, yet little is known about how these relationships evolve throughout adolescence or how they are differentially associated with mental health. Important distinctions could also be made regarding activity types. The sample consisted of 292 participants (58% female; M age = 12.
