The Superiority of European Kidney Function Consortium Cystatin C-Based Formula for Risk Stratification of All-Cause and Cardiovascular Deaths in US Adults.

Introduction: We intended to compare the predictive value for all-cause and cardiovascular deaths between estimated glomerular filtration rate (eGFR) derived from the European Kidney Function Consortium (EKFC) cystatin C-based formula, the EKFC creatinine-based formula, and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) cystatin C- or creatinine-based formulas.

Methods: Overall, 4,132 participants from the National Health and Nutrition Examination Survey between 1999 and 2002 were included, and death information was obtained through the National Death Index. To compare predictive accuracy between EKFC eGFRcys (EKFC cystatin C-based formula), CKD-EPI eGFRcys (CKD-EPI cystatin C-based formula), EKFC eGFRcr (EKFC creatinine-based formula), and CKD-EPI eGFRcr (CKD-EPI creatinine-based formula), we conducted time-dependent receiver operator characteristic (ROC) curves and reclassification analysis.

Association of Total Mortality and Cardiovascular Endpoints With the Timing of the First and Second Systolic Peak of the Aortic Pulse Wave.

Prognostic significance of the timing in the cardiac cycle of the first (TP1) and second (TP2) systolic peak of the central aortic pulse wave is ill-defined. Incidence rates and standardized multivariable-adjusted hazard ratios (HRs) of adverse health outcomes associated with TP1 and TP2, estimated by the SphygmoCor software, were assessed in the International Database of Central Arterial Properties for Risk Stratification (IDCARS) (n = 5529). Model refinement was assessed by the integrated discrimination (ID) and net reclassification (NR) improvement.

Optimal predictive features were identified through the least absolute shrinkage and selection operator regression technique, and nomograms were constructed using multivariate logistic regression.

Beta cell extracellular vesicle PD-L1 as a novel regulator of CD8 T cell activity and biomarker during the evolution of type 1 diabetes.

Aims/hypothesis: Surviving beta cells in type 1 diabetes respond to inflammation by upregulating programmed death-ligand 1 (PD-L1) to engage immune cell programmed death protein 1 (PD-1) and limit destruction by self-reactive immune cells. Extracellular vesicles (EVs) and their cargo can serve as biomarkers of beta cell health and contribute to islet intercellular communication. We hypothesised that the inflammatory milieu of type 1 diabetes increases PD-L1 in beta cell EV cargo and that EV PD-L1 may protect beta cells against immune-mediated cell death.
