Homeostatic Kinematic Growth Model for Arteries -- Residual Stresses and Active Response [PDF]

arXiv
A simple kinematic growth model for muscular arteries is presented which allows the incorporation of residual stresses such that a homeostatic in-vivo stress state under physiological loading is obtained. To this end, new evolution equations for growth are proposed, which avoid issues with instability of final growth states known from other kinematric ...

Evaluation of the Extension of the Cerebral Blood Flow and its Main Parameters [PDF]

arXiv, 1999
Among the major factors controlling the cerebral blood flow (CBF) - cerebral perfusion pressure, arterial partial pressure of oxygen (PaO2), cerebral metabolism, arterial partial pressure of carbon dioxide (PaCO2), and cardiac output, the effect of PaCO2 is peculiar in being independent of autoregulatory CBF mechanisms and it allows to explore the full

Pressure‐Wire Guided Hybrid Branch Pulmonary Artery Band Placement for Palliation of Single Ventricle and Critical Congenital Cardiac Lesions

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Historically, bilateral pulmonary artery band (PAB) placement was guided by pulmonary blood flow surrogates including systemic blood pressure (BP) and arterial saturation. These metrics alone may result in suboptimal bPAB placement.

Salvage Trans‐Sylvian Peri‐Insular Hemispherotomy After Embolic Hemispherectomy

Annals of the Child Neurology Society, EarlyView.
ABSTRACT Background Hemispherectomy and hemispherotomy represent well‐established treatments for drug‐resistant hemispheric epilepsy. An alternative endovascular procedure has been explored for cases with challenging surgical anatomy, which seeks to achieve the clinical effect of hemispherectomy via embolization of the major cerebral arteries and ...

Manganese Neurotoxicity and Familial Disorders of Manganese Transport

Annals of the Child Neurology Society, EarlyView.
ABSTRACT Manganese is the 12th most common element in the Earth's crust and is an essential industrial component. Biologically, this metal plays an important role as a constituent of numerous enzymes. While manganese is required for normal biochemical and physiological processes, manganese excess can lead to significant toxicity, particularly to the ...

In silico analysis of embolism in cerebral arteries using fluid-structure interaction method

Heliyon
Ischemic stroke, particularly embolic stroke, stands as a significant global contributor to mortality and long-term disabilities. This paper presents a comprehensive simulation of emboli motion through the middle cerebral artery (MCA), a prevalent site ...

Quantification of Collateral Supply with Local-AIF Dynamic Susceptibility Contrast MRI Predicts Infarct Growth [PDF]

arXiv
In ischemic stroke, leptomeningeal collaterals can provide compensatory blood flow to tissue at risk despite an occlusion, and impact treatment response and infarct growth. The purpose of this work is to test the hypothesis that local perfusion with an appropriate Local Arterial Input Function (AIF) is needed to quantify the degree of collateral blood ...

Infant Death due to Cannabis Ingestion

Drug Testing and Analysis, EarlyView.
ABSTRACT A child died in the emergency room of a local hospital a few hours after ingesting a substance the color of cork and the consistency of earth. At home, a modest amount of resinous substance was found. At the hospital, the child exhibited alterations in walking, balance, and consciousness.

Nationwide resource utilization of dizziness/vertigo presentations to the ED

Eye &ENT Research, EarlyView.
Abstract Objective This study aims to assess overall rates of neuroimaging (computed tomography [CT] or magnetic resonance imaging [MRI]) and cerebrovascular accidents (CVAs) in patients presenting to the emergency department (ED) with primary diagnoses of dizziness/vertigo to determine if neuroimaging is overused in this population.

Long‐term cardiovascular outcomes of immune checkpoint inhibitor‐related myocarditis: A large single‐centre analysis

ESC Heart Failure, Volume 12, Issue 2, Page 1237-1245, April 2025.
Abstract Aims Immune checkpoint inhibitors (ICI) are the cornerstone of modern oncology; however, side effects such as ICI‐related myocarditis (irM) can be fatal. Recently, Bonaca proposed criteria for irM; however, it is unknown if they correlate well with cardiovascular (CV) ICI‐related adverse events.
