“Carotid body”

A 70-year-old woman presented to our emergency department with a severe left-sided headache. The headache's location and accompanying symptoms are consistent with paroxysmal hemicrania. On workup, a cervical computed tomography scan incidentally revealed a left carotid body tumor, and the patient was referred to vascular surgery. After the resection of the tumor, the patient recovered well in the following months. Furthermore, she no longer experienced any additional headache episodes, which were likely caused by the carotid body tumor...

Pheochromocytomas (PCC) and paragangliomas (PGL) are rare neuroendocrine tumors. Head and neck paragangliomas (HNPGL) can be categorized into carotid body tumors, which are the most common, as well as jugular, tympanic, and vagal paraganglioma. A review of the current literature was conducted to consolidate knowledge concerning PGL mutations, familial occurrence, and the practical application of this information. Available scientific databases were searched using the keywords head and neck paraganglioma and genetics, and 274 articles in PubMed and 1183 in ScienceDirect were found...

OBJECTIVE: Few studies have evaluated the rapid progression of carotid stenosis on a large scale. We created a custom software algorithm to analyze an electronic medical record database to examine the natural progression of carotid stenosis, identify a subset of patients with rapid progression, and evaluate the specific patient risk factors associated with this rapid progression. METHODS: Patients in a large integrated healthcare system who had undergone two or more carotid ultrasound scans from August 2010 to August 2018 were identified...

Objective: To evaluate the association of abdominal obesity and obesity types with carotid intima-media thickness (cIMT) in children and provide scientific evidence for the prevention of abnormal vascular structure. Methods: Based on the "Children's Cardiovascular Health Cohort" conducted in Huantai county of Zibo, Shandong province from November 2017 to January 2018, a total of 1 240 children, including 657 boys (53.0%), who had completed data of sex, age, physical examinations, blood biochemical indices and lifestyle variables (collected by questionnaires) were included for the analysis...

BACKGROUND: Postmenopausal women are more likely to have uncontrolled hypertension and are at higher risk of cardiovascular disease compared with age-matched men. Blood pressure variability is emerging as a predictor of adverse cardiovascular outcomes and may be implicated in the relationship between menopause and worsened vascular health in women. We conducted an observational study, BRAVE (Blood pRessure And Vascular hEalth around menopause) to study this relationship. METHOD: Normotensive perimenopausal women were recruited...

Background: Emerging evidence suggests that structural adventitial modifications and perivascular adipose tissue (PAT) may have a role in early atherogenesis. In a cohort of children and adolescents, we explored (1) the association of carotid extra-media thickness (cEMT), an ultrasound measure whose main determinants are arterial adventitia and PAT, with obesity and its cardiometabolic complications; and (2) the interplay between cEMT and endothelial function. Methods: The study participants included 286 youths (age, 6-16 years; 154 boys, and 132 girls)...

OBJECTIVES: To evaluate carotid stiffening in participants without conventional cardiovascular risk factors (CVRFs) by using ultrafast pulse wave velocity (ufPWV). METHODS: The present study enrolled 517 participants without conventional CVRFs (CVRF-Free total population).

An exponential rise in patient data provides an excellent opportunity to improve the existing health care infrastructure. In the present work, a method to enable cardiovascular digital twin is proposed using inverse analysis. Conventionally, accurate analytical solutions for inverse analysis in linear problems have been proposed and used. However, these methods fail or are not efficient for nonlinear systems, such as blood flow in the cardiovascular system (systemic circulation) that involves high degree of nonlinearity...
