The Impact of Small Artery Disease (SAD) and Medial Arterial Calcification (MAC) Scores on Chronic Wound and Amputation Healing: Can It Tell Us More?

Background: In 2021, Ferraresi et al. created a novel scoring system based on the impact of small artery disease (SAD) and medial arterial calcification (MAC) on wound healing. SAD and MAC scores functioned similar to Wound, Ischemia, and foot Infection (WIfI) but with minimal resource expenditure.

Biomechanical dysregulation of SGK-1 dependent aortic pathologic markers in hypertension.

Introduction: In hypertension (HTN), biomechanical stress may drive matrix remodeling through dysfunctional VSMC activity. Prior evidence has indicated VSMC tension-induced signaling through the serum and glucocorticoid inducible kinase-1 (SGK-1) can impact cytokine abundance. Here, we hypothesize that SGK-1 impacts production of additional aortic pathologic markers (APMs) representing VSMC dysfunction in HTN.

Inhibition of miR-33a-5p in Macrophage-like Cells In Vitro Promotes apoAI-Mediated Cholesterol Efflux.

Atherosclerosis is caused by cholesterol accumulation within arteries. The intima is where atherosclerotic plaque accumulates and where lipid-laden foam cells reside. Intimal foam cells comprise of both monocyte-derived macrophages and macrophage-like cells (MLC) of vascular smooth muscle cell (VSMC) origin.

Hostile neck anatomy contributes to higher rates of reintervention following endovascular aortic repair for ruptured infrarenal abdominal aortic aneurysm.

Introduction: Ruptured abdominal aortic aneurysms (AAA) presenting with hostile neck anatomy can represent a challenge in surgical decision-making. We hypothesized that, patients who require reinterventions have higher rates of compromised neck anatomy at initial presentation and may indicate a need for altered surveillance paradigm.

Methods: Patients presenting with ruptured AAA to a single tertiary care institution from 2014 to 2021 were retrospectively reviewed.

MOVAS Cells: A Versatile Cell Line for Studying Vascular Smooth Muscle Cell Cholesterol Metabolism.

Cholesterol metabolism is paramount to cells. Aberrations to cholesterol metabolism affects cholesterol homeostasis, which may impact the risk of several diseases. Recent evidence has suggested that vascular smooth muscle cell (VSMC) cholesterol metabolism may play a role in atherosclerosis.
