Article Synopsis
- The study investigates racial and ethnic disparities in the use of forearm arteriovenous access (AVA) for hemodialysis initiation, finding that Black and Hispanic patients are less likely to have forearm AVAs compared to White patients.
- A retrospective analysis of over 70,000 patients from DaVita Kidney Care revealed a significant decline in the proportion of forearm AVA use, dropping from 49% in 2006 to 29% in 2019, without any differences in this trend among racial and ethnic groups.
- The results highlight persistent inequalities in AVA location choices among different races, suggesting a need for further research into the underlying factors contributing to these differences.
Recent advances in 3D printing have enabled the manufacture of porous electrodes which cannot be machined using traditional methods. With micron-scale precision, the pore structure of an electrode can now be designed for optimal energy efficiency, and a 3D printed electrode is not limited to a single uniform porosity. As these electrodes scale in size, however, the total number of possible pore designs can be intractable; choosing an appropriate pore distribution manually can be a complex task.

However, conventional thick electrodes increase ion diffusion length and cause larger ion concentration gradients, limiting reaction kinetics. We demonstrate a strategy for building interpenetrated structures that shortens ion diffusion length and reduces ion concentration inhomogeneity.
