Unraveling the transcriptomic landscape of brain vascular cells in dementia: A systematic review.
Alzheimers Dement
January 2025
UK Dementia Research Institute at the University of Edinburgh, Edinburgh, UK.
Introduction: Cerebrovascular dysfunction plays a critical role in the pathogenesis of dementia and related neurodegenerative disorders. Recent omics-driven research has revealed associations between vascular abnormalities and transcriptomic alterations in brain vascular cells, particularly endothelial cells (ECs) and pericytes (PCs). However, the impact of these molecular changes on dementia remains unclear.

January 2025
State Key Laboratory of Component-Based Chinese Medicine, Tianjin University of Traditional Chinese Medicine, Tianjin, 301617, People's Republic of China.
Purpose: The major cardiac voltage-gated sodium channel Na1.5 (I) is essential for cardiac action potential initiation and subsequent propagation. Compound Chinese medicine Wenxin Keli (WXKL) has been shown to suppress arrhythmias and heart failure.

J Soc Cardiovasc Angiogr Interv
December 2024
Imperial College London, United Kingdom.
Background: The mechanistic association between the hydraulic forces generated during contrast injection and the risk of coronary injury is poorly understood. In this study, we sought to evaluate whether contrast injections increase intracoronary pressures beyond resting levels and estimate the risk of hydraulic propagation of coronary dissections.
Methods: This is a prospective, single-arm, multicenter study that included patients with nonculprit, non-flow-limiting coronaries.
De Novo Atherosclerotic Renal Artery Stenosis Covered Stent Treatment for Resistant Hypertension (ARTISAN) Results.
J Soc Cardiovasc Angiogr Interv
December 2024
The University of Toledo, Toledo, Ohio.
Background: Atherosclerotic renal artery stenosis (ARAS) may provoke hypertension and/or impaired kidney function. Some patients develop uncontrolled hypertension and deteriorating kidney function despite optimal medical therapy. In these patients, endovascular treatment is an important therapeutic option.

J Soc Cardiovasc Angiogr Interv
December 2024
Cincinnati Children's Hospital Medical Center, Cincinnati, Ohio.
Background: Advancements in cardiac catheterization have improved survival for pediatric congenital heart disease patients, but the associated ionizing radiation risks necessitate ethical consideration.
Methods: This study presents an empirical model, developed from 3131 unique pediatric procedures, to establish alert levels based on a patient's lateral thickness of the thorax for various procedural categories during diagnostic or interventional cardiac catheterization. The model uses linear regression of logarithmic reference air kinetic energy released per unit mass (KERMA) and air KERMA area product, also referred to as dose area product, to set alert levels at the top 95% and 99% of patient data.
