Article Abstract
Key Points: Most prevalent patients with advanced CKD are unable to select any KRT modality for themselves, highlighting concerns with advanced CKD clinical care. Prior receipt of KRT-directed education is associated with greater KRT decision readiness and home dialysis selection. Objective disease knowledge is among the strongest and most modifiable predictors of the KRT decision readiness, its quality, and home dialysis choice.
Background: Kidney disease stakeholders recommend a system-wide increase in home dialysis use. KRT decision readiness is associated with higher selection and use of home dialysis; however, KRT decision making is complex, and factors informing KRT decision readiness in patients with advanced CKD are unclear.
Methods: Using the baseline data of the Trial to Evaluate and Assess the effects of Comprehensive KRT-directed patient education on home dialysis use among VETerans, we conducted a cross-sectional analysis to evaluate prevalent KRT decision readiness, defined as ability to choose any KRT modality among US Veterans with advanced CKD. We also evaluated Veterans' ability to achieve high-quality informed KRT decisions (more than 60% decisional confidence on a scale ranging from 1% to 100%) and selection of home dialysis as secondary outcomes. Univariate and multivariable logistic regressions were used to test associations between patient-level variables and outcomes.
Results: Of the 468 enrollees with a complete baseline dataset, 282 (60%) could not pick any KRT modality; the rest were split between high (20%) versus low-quality (20%) decisions and home (21%) versus in-center (12%) dialysis. Younger age, higher CKD stage, history of receiving prior KRT-directed education, rural habitation, and objective disease knowledge were positively associated with KRT decision readiness. Only objective disease knowledge was associated with KRT decision readiness after adjustments, with participants in the highest tertile of CKD-specific knowledge having two-fold (odds ratio, 2.31; 95% confidence interval, 1.18 to 4.55) and KRT-specific knowledge having five-fold (odds ratio, 5.16; 95% confidence interval, 2.63 to 10.32) higher odds of selecting their KRT. Item-level analysis showed that difficult, specifically KRT knowledge-related, items had a high discriminatory capacity to predict KRT decision readiness.
Conclusions: Veterans with advanced CKD are ill-prepared for KRT decision making. Although social determinants of health have a potential role in identifying high-risk populations, objective kidney failure and KRT-specific knowledge have a dominant effect on KRT decision readiness.

The kynurenine (KYN) metabolic pathway sits at the crossroads of immunity, metabolism, and neurobiology, yet its clinical translation remains fragmented. Emerging spatial omics, wearable chronobiology, and synthetic microbiota studies reveal that tryptophan (Trp) metabolism is regulated by distinct cellular "checkpoints" along the gut-brain axis, finely modulated by sex differences, circadian rhythms, and microbiome composition. However, current interventions tackle single levers in isolation, leaving a key gap in the precision control of Trp's fate.

There are substantial inequities both within and between countries in the availability of kidney replacement therapy (KRT), chronic kidney disease care, and a specialized nephrology workforce. Healthcare policies are the foundation for optimal population health and quality health care. In this article, we present 5 country case studies to illustrate how Thailand, Uruguay, India, South Africa, and the United States have made progress in reducing kidney health inequities through healthcare policy change.

Background: Predictors of major adverse kidney events (MAKE) in focal segmental glomerulosclerosis (FSGS) have not been previously explored within large, real-world populations. The study aim was to evaluate population-level predictors of MAKE attributed to FSGS from health system data.
Methods: The study population was derived from electronic health records from Providence and University of California Los Angeles Health Systems.

Objective: Our study aims to define the rates of mortality and nonfatal complications in patients with kidney failure undergoing elective endovascular aortic aneurysm repair (EVAR) for the management of infrarenal abdominal aortic aneurysm (AAA) in Australia and New Zealand.
Methods: A retrospective binational data linkage between the Australia and New Zealand Dialysis and Transplant Registry (ANZDATA) and state-based health-related datasets identified patients receiving chronic kidney replacement therapy (KRT) who underwent EVAR for AAA between January 1, 2000, and December 31, 2015. Linked data were interrogated to define patient demography, modality of KRT, date of death, and the occurrence of specific nonfatal complications.
