Pre‐operative transcranial Doppler ultrasound assessment of cerebral collateral circulation in children undergoing veno‐arterial extracorporeal membrane oxygenation or cardiac surgery

open access: yesJournal of Medical Radiation Sciences, EarlyView.
A pre‐cannulation survey of the circle of Willis (CoW) using transcranial Doppler (TCD) ultrasound was implemented to assess cerebral collateral circulation in children undergoing VA ECMO or cardiac surgery with cervical cannulation. The technique, in use since 2019, employs high‐end ultrasound platforms to assess brain morphology, haemorrhage and ...

Ultrasound Evaluation of the Changes of Ophthalmic Artery Doppler and Optic Nerve Sheath in Pregnant Women With FGR

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Objectives This study aimed to compare changes in ultrasonic Doppler parameters, particularly the peak ratio (PR) of the ophthalmic artery (OA) and optic nerve sheath diameter (ONSD), in pregnancies complicated by fetal growth restriction (FGR). Furthermore, it sought to evaluate differences in these parameters across various subgroups and analyze the ...

Local Search and the Evolution of World Models

open access: yesTopics in Cognitive Science, EarlyView., 2023
Abstract An open question regarding how people develop their models of the world is how new candidates are generated for consideration out of infinitely many possibilities. We discuss the role that evolutionary mechanisms play in this process. Specifically, we argue that when it comes to developing a global world model, innovation is necessarily ...

The heart, a secondary organ in the control of blood circulation

open access: yesExperimental Physiology, EarlyView., 2023
Abstract Circulation of the blood is a fundamental physiological function traditionally ascribed to the pressure‐generating function of the heart. However, over the past century the ‘cardiocentric’ view has been challenged by August Krogh, Ernst Starling, Arthur Guyton and others, based on haemodynamic data obtained from isolated heart preparations and
