Authors: Wang H, Liu Z, Shen Z, Fang L, Zhang S Abstract OBJECTIVES: To identify the predictors of coronary involvement, and to determine the impact of coronary involvement on long-term outcomes in patients with Takayasu's arteritis (TAK). METHODS: This retrospective cohort study of TAK patients with coronary evaluation by angiography or computed tomography angiography was conducted in a tertiary center between 1990 and 2018. Risk factors for coronary involvement and predictors of overall survival, cardiovascular event-free survival, and relapse-free survival were investigated. RESULTS: The median follow-up...

Background: There is conflicting data on the effect of carotid revascularization on cognitive function. Objective: To examine cerebral blood flow and cognitive function after carotid revascularization. Methods: Patients with unilateral, asymptomatic hemodynamically significant carotid artery stenosis (80% by computed tomography angiography or magnetic resonance angiography) were eligible. Cerebral blood flow was measured preoperatively and 1 month postoperatively using quantitative phase contrast magnetic resonance angiography.

INTRODUCTION Admission computed tomography (CT) is a widely used diagnostic tool for patients with pelvic fractures. In this pilot study, we hypothesized that pelvic hematoma volumes derived using a rapid automated deep learning-based quantitative visualization and measurement algorithm predict interventions and outcomes including (a) need for angioembolization (AE), pelvic packing (PP), or massive transfusion (MT), and (b) in-hospital mortality. METHODS We performed a single-institution retrospective analysis of 253 patients with bleeding pelvic fractures who underwent admission abdominopelvic trauma CT between 2008 ...

Abstract OBJECTIVE: People with HIV (PWH) who are well treated on antiretroviral therapy remain at increased risk for body composition changes, including increased visceral adipose tissue (VAT) and reduced subcutaneous adipose tissue (SAT), as well as increased cardiovascular disease (CVD). The relationship between adipose compartments and coronary disease is not well understood among PWH. METHODS: A total of 148 PWH and 68 uninfected individuals without CVD were well phenotyped for VAT and SAT via single-section abdominal computed tomography (CT) at L4. Coronary artery calcium (CAC) score was assessed by non...

We thank Lan éelle et al for their interest in our recent article.1 We also want to commend the authors for their excellent publication demonstrating the ability of transcutaneous oxygen pressure (TcPO2) of the calf and buttock, applied during a treadmill exercise test, to identify patients who have significan t lower extremity atherosclerotic burden as measured by computed tomography angiography.2 Both TcPO2 and near-infrared spectroscopy (NIRS) represent exciting methods to measure the balance of oxygen delivery, demand, and utilization in the legs of patients with peripheral artery disease (PAD) in rea l time.
