A new approach to making scientific research more efficient - rethinking sustainability.

As interest in sustainability grows, many researchers raise questions about changing scientific practices. To enable effective change, we reconceptualize sustainability as an approach that optimizes the efficiency of procedures, thereby benefiting scientists and minimizing environmental footprints. Since the implementation of sustainable approaches can be challenging, we describe the 6R concept as a framework to arrive at actionable steps.

Sonographic Venous Velocity Index Identifies Patients with Chronic Kidney Disease and Severe Diastolic Dysfunction.

Objective: Diagnosing cardiorenal syndrome (CRS) in patients with chronic kidney disease (CKD) continues to remain challenging in outpatient practice. In this study, we investigate whether a newly developed venous velocity ultrasound index (VVI) can differentiate between patients with CRS and patients with CKD of other cause or normal renal function (NRF).

Methods: Patients with CRS (n 30), CKD (n=30), and NRF (n=30) were included in the study.
