Background And Objectives: Chronic kidney disease (CKD) is known to be associated with increased plasma phosphorylated tau217 (p-tau217) concentrations, potentially confounding the utility of plasma p-tau217 measurements as a marker of amyloid pathology in individuals with suspected Alzheimer disease (AD). In this study, we quantitatively investigate the relationship of plasma p-tau217 concentrations vs estimated glomerular filtration rate (eGFR) in individuals with CKD with and without amyloid pathology.
Methods: This was a retrospective examination of data from 2 observational cohorts from either the Mayo Clinic Study of Aging or the Alzheimer's Disease Research Center cohorts.

It is urgent for patients with chronic kidney disease (CKD) to develop a robust and facile therapy for effective control of serum phosphate and reasonable regulation of gut microbiota, which are aiming to prevent cardiovascular calcification and reduce cardiovascular complications. Here, bioinspired by intestinal microstructures, we developed biomimetic wrinkled prebiotic-containing microspheres with enhanced intestinal retention and absorption for reducing hyperphosphatemia and vascular calcification of CKD model rats. The resultant CSM@5 microspheres exhibited favorable phosphate binding capacity in vitro and could effectively reduce serum concentration of phosphorous in vivo.

Background: Individuals with end-stage renal disease may be at increased risk of sudden cardiac arrest (SCA) associated with dialysis therapy. However, community-based studies with comprehensive adjudication of SCA are lacking.
Methods: We conducted a community-based study using a case-case study design in a US population of ≈1 million.

Hypoparathyroidism (hypoPTH), sensorineural deafness, and renal dysplasia (HDR) syndrome is a rare autosomal dominant condition with approximately 200 cases published. HDR syndrome is caused by variants of GATA binding protein 3 gene (), which encodes a transcription factor, with multiple types of variants reported. We present the case of a 76-year-old woman who was diagnosed with hypoPTH when she was aged 40 years and transferred care to our institution.

Rationale & Objective: In the general population, neighborhood socioeconomic status (SES) has been found to be associated with cardiovascular risk, but this relationship has not been well studied among patients with chronic kidney disease (CKD). This study seeked to evaluate the association between neighborhood SES and cardiovascular outcomes in a CKD cohort.
Study Design: Multicenter prospective cohort.
