Fractal Rigidity in Migraine [PDF]

open access: yes, 2003
We study the middle cerebral artery blood flow velocity (MCAfv) in humans using transcranial Doppler ultrasonography (TCD). Scaling properties of time series of the axial flow velocity averaged over a cardiac beat interval may be characterized by two ...

Transcranial Color‐Coded Duplex Sonography in Large‐Vessel Vasculitis Compatible With Takayasu Arteritis Presenting Intracranial Involvement and Vertebrobasilar Dolichoectasia: A Case Report

open access: yesJournal of Clinical Ultrasound, EarlyView.
This case illustrates sequential intracranial occlusions in large‐vessel vasculitis compatible with Takayasu arteritis preserving perfusion through robust collateral pathways. Transcranial color‐coded duplex sonography identified characteristic blunted flow patterns and focal turbulence, underscoring its value in detecting hemodynamic compromise beyond

Transcranial Doppler Ultrasonography for the Management of Severe Traumatic Brain Injury After Decompressive Craniectomy.

open access: yesWorld Neurosurgery, 2019
BACKGROUND Cerebral hemodynamic transformation is a relatively common finding in patients with traumatic brain injury (TBI). Knowledge of cerebral hemodynamic disturbance may assist in predicting the management outcome.

Guidelines for Essential Trauma Care: Second Edition (2026)

open access: yesWorld Journal of Surgery, EarlyView.
Injury is a major cause of death and disability globally, with the highest burden in low‐ and middle‐income countries (LMICs). Strengthening the organization and planning for trauma care (care of the injured) can improve care and lower mortality. In 2004, the International Association for Trauma Surgery and Intensive Care (IATSIC) and the World Health ...

Effects of Prone Position and Positive End-Expiratory Pressure on Noninvasive Estimators of ICP: A Pilot Study. [PDF]

open access: yes, 2016
BACKGROUND: Prone positioning and positive end-expiratory pressure can improve pulmonary gas exchange and respiratory mechanics. However, they may be associated with the development of intracranial hypertension.

Academic and cerebrovascular outcomes after neurodevelopmental screening in sickle cell disease: A longitudinal cohort study

open access: yesDevelopmental Medicine &Child Neurology, EarlyView.
Neurodevelopmental screening in toddlers or preschoolers with sickle cell disease (SCD) predicts future academic deficits. Screening sensitivity for future academic deficits is highest in preschoolers with SCD. Brief neurodevelopmental screening tools can identify high risk children for early intervention. Abstract Aim To assess the predictive validity

All Is Relative—A Call for Considering “Physiologically Informed” Control Conditions to Improve the Mechanistic Understanding of the Effects of Physical Exercise on Cognition

open access: yesScandinavian Journal of Psychology, EarlyView.
ABSTRACT There is a growing interest in elucidating the mechanisms that drive the benefits of physical exercise on cognitive performance. A key element for a better understanding of a particular phenomenon (e.g., the mediators of the exercise‐cognition interaction) is the selection of an appropriate control condition/group as the basis for causal ...
