Contemporary Review to Reduce Groin Surgical Site Infections in Vascular Surgery.

Surgical site infection (SSIs) in lower extremity vascular procedures is a major contributor to patient morbidity and mortality. Despite previous advancements in preoperative and postoperative care, the surgical infection rate in vascular surgery remains high, particularly when groin incisions are involved. However, successfully targeting modifiable risk factors reduces the surgical site infection incidence in vascular surgery patients.

Noninvasive molecular imaging of apoptosis in a mouse model of anthracycline-induced cardiotoxicity.

Background: Anthracycline-induced cardiotoxicity and myocardial dysfunction may be associated with apoptosis. Caspase 3 catalyzes a terminal step in apoptosis, and its expression may serve as a marker of cardiomyocyte apoptosis. We synthesized 18F-CP18, a caspase-3 substrate and evaluated cardiac 18F-CP18 uptake in a mouse model of anthracycline cardiotoxicity.

Atherosclerotic plaque uptake of a novel integrin tracer ¹⁸F-Flotegatide in a mouse model of atherosclerosis.

Introduction: Rupture of unstable atherosclerotic plaque that leads to stroke and myocardial infarction may be induced by macrophage infiltration and neovessel formation. A tracer that selectively binds to integrin αvβ3 a protein expressed by macrophages and neovascular endothelium may identify rupture prone plaque.

Methods: (18)F-labeled "R-G-D" containing tripeptide (Flotegatide), a click chemistry derived radiotracer that binds to integrin αvβ3 was injected in ApoE knockout mice fed a high fat diet.
