Potential of Urine Biomarkers CHI3L1, NGAL, TIMP-2, IGFBP7, and Combinations as Complementary Diagnostic Tools for Acute Kidney Injury after Pediatric Cardiac Surgery: A Prospective Cohort Study.

Acute kidney injury (AKI) is common after pediatric cardiac surgery (CS). Several urine biomarkers have been validated to detect AKI earlier. The objective of this study was to evaluate urine CHI3L1, NGAL, TIMP-2, IGFBP7, and NephroCheck as predictors for AKI ≥ 1 in pediatric CS after 48 h and AKI ≥ 2 after 12 h.

MR Angiography Series: Fundamentals of Contrast-enhanced MR Angiography.

The Society for Magnetic Resonance Angiography (SMRA) is a group of researchers and clinicians who are passionate about the benefits of MR angiography (MRA) but understand its challenges. Their mission is to study MRA, continually improve and innovate for the benefit of patients, and most important, educate the medical community so they can take full advantage of the benefits of MRA and overcome its challenges. In support of that mission, the authors have created a series of self-learning modules on behalf of the SMRA to demystify MRA protocols and help the reader perform patient-friendly high-quality MRA on a routine basis in clinical practice.
