Systolic blood pressure time in target range (SBP TTR) is a novel metric for control. Previous studies have demonstrated an inverse association between SBP TTR and risks of cardiovascular events, but sex differences never been reported. This study aims to investigate the sex-specific relationship using data from Blood Pressure Intervention Trial (SPRINT). post hoc analysis included 8822 SPRINT participants with at least three follow-up systolic (SBP) measurements within first months. was calculated Rosendaal method linear interpolation.

ABSTRACT Cardiovascular diseases are one of the leading causes global mortality. Treatment methods such as bypass graft operations, while often successful, can fail in cases systemic disease or compliance mismatch. Tissue engineered vascular grafts may offer a potential solution, by means an implantable cell‐seeded scaffold that integrate into site. Modifications to cell culture environment, through physical modification structure, culturing cells dynamic fluidic have been shown alter cellular behavior. Herein, we combine these two approaches incorporating electrospun polycaprolactone scaffolds consisting smooth and modified fiber surface topographies within series novel 3D printed microfluidic bioreactors. The bioreactors successfully maintained viability human umbilical vein endothelial over 24‐h period, with static dimpled under indicating highest viability.

Disturbed flow is one of the pathological initiators endothelial dysfunction in intimal hyperplasia (IH) which commonly seen vascular bypass grafts, and arteriovenous fistulas. Various vitro disease models have been designed to simulate hemodynamic conditions found vasculature. Nonetheless, prior investigations encountered challenges establishing a robust disturbed model, primarily attributed complex bifurcated geometries distinctive dynamics. In present study, we aim address this gap by introducing an model capable inducing other hemodynamics patterns through pulsatile same model. To assess model's validity, employed computational fluid dynamics (CFD) compared morphology functions human umbilical venous cells (HUVECs) under those physiological or stagnant conditions. CFD analysis revealed generation within pinpointing specific location channel where effects were observed. High-content screening, single-cell morphological profile assessment, demonstrated that HUVECs area exhibited random orientation, features significantly distinct condition after two days exposure. Furthermore, exposed underwent extensive remodeling adherens junctions expressed higher levels cell activation markers conclusion, our provides platform for investigating associations between pattern diseases.
