A nonlinear beamforming for enhanced spatiotemporal sensitivity in high frame rate ultrasound flow imaging.

Comput Biol Med 2022 Jun 2;147:105686. Epub 2022 Jun 2.

Center for Computational Imaging, Department of Electrical Engineering, Indian Institute of Technology (IIT) Palakkad, India.

Typically, an ultrasound flow imaging system employs the conventional delay and sum (DAS) beamformer due to its inherent low complexity. But the conventional DAS technique offers poor contrast, low imaging resolution, and limited spatiotemporal sensitivity. This article attempts to improve the spatiotemporal sensitivity of the conventional flow imaging with a novel multiply and sum based nonlinear high-resolution (NLHR) beamforming approach. Read More

Number of Teeth and Nutritional Status Parameters Are Related to Intima-Media Thickness in Dalmatian Kidney Transplant Recipients.

J Pers Med 2022 Jun 16;12(6). Epub 2022 Jun 16.

Department of Internal Medicine, School of Medicine, University of Split, 21000 Split, Croatia.

Although kidney transplantation significantly improves the quality of life of patients with end-stage renal disease (ESRD), the prevalence of cardiovascular disease (CVD) in kidney transplant recipients (KTRs) remains high. Atherosclerosis, post-transplantation metabolic changes, immunosuppressive therapy, and periodontitis contribute to elevated cardiovascular risk in this population. The aim of the study was to evaluate carotid intima-media thickness (IMT) as a surrogate marker of atherosclerosis and to analyze the possible risk factors for IMT in Dalmatian KTRs. Read More

Percutaneous Ultrasound-Guided Carotid Access and Puncture Closure with Angio-Seal in Horses.

Animals (Basel) 2022 Jun 7;12(12). Epub 2022 Jun 7.

Veterinary Hospital of the University of Zaragoza (HVUZ), C/Miguel Servet 177, 50013 Zaragoza, Spain.

There are different indications for endovascular surgery in horses, mainly the treatment of guttural pouch mycosis. Traditionally, these procedures are carried out by open arteriotomy of the common carotid artery (CCA), although less invasive percutaneous ultrasound-guided carotid access (PUGCA) has been described in experimental horses. In human medicine, commercial closure systems are used to seal these arterial puncture sites and reduce complications. Read More

The Association Between Carotid Flow Time and Fluid Responsiveness in Children Under General Anesthesia.

Paediatr Anaesth 2022 Jun 23. Epub 2022 Jun 23.

Department of Anesthesiology and Critical Care Medicine, The Children's Hospital of Philadelphia, Philadelphia, PA, USA.

Background: Fluid administration in children undergoing surgery requires precision, however, determining fluid responsiveness can be challenging. Ultrasound has been used widely in the emergency department and intensive care units as a non-invasive, bedside manner of determining volume status, but the intraoperative period presents unique challenges as often the chest and abdomen are inaccessible for ultrasound. We investigate whether carotid artery ultrasound, specifically carotid flow time, can be used to determine fluid responsiveness in children under general anesthesia. Read More

A new approach of statin therapy in carotid atherosclerosis: Targeting indices of plaque vulnerability on the top of lipid-lowering. A narrative review.

Kardiol Pol 2022 Jun 23. Epub 2022 Jun 23.

2nd Department of Internal Medicine, Research Institute and Diabetes Centre, Athens University Medical School, Attikon University General Hospital, Athens, Greece.

Novel imaging techniques and biomarkers have emerged as surrogate markers of carotid plaque vulnerability. In parallel, statins' administration in patients with established carotid atherosclerosis not requiring revascularization have reduced the consequent cerebrovascular events. This is not only attributed to the lipid-lowering properties of statins, but to their pleiotropic actions as well. Read More
