3-D half-spheroid models for transcranial doppler ultrasound propagation channels
In this paper, a method of characterization of a transcranial Doppler (TCD) ultrasound propagation channel is proposed. A simplified 3-D isotropic half-spheroid scattering channel model is described.

Occurrence of vasospasm and infarction in relation to a focal monitoring sensor in patients after SAH: placing a bet when placing a probe? [PDF]
Introduction: Vasospastic brain infarction is a devastating complication of aneurysmal subarachnoid hemorrhage (SAH). Using a probe for invasive monitoring of brain tissue oxygenation or blood flow is highly focal and may miss the site of cerebral ...

ABSTRACT Management of cerebral vasculopathy in sickle cell anemia (SCA) includes standard‐care, that is, chronic transfusion (CT) or hydroxyurea, and hematopoietic cell transplantation (HCT). DREPAGREFFE‐1 (December 2010/June 2013), a French multicenter trial, was the first prospective trial comparing standard‐care to match sibling donor (MSD)‐HCT in ...

Detection of paradoxical cerebral echo contrast embolization by transcranial Doppler ultrasound.
Contrast echocardiography has been shown to be a sensitive method for detecting patent foramen ovale in embolic stroke, implying paradoxical embolization.

ABSTRACT Background Intensive care following resuscitation from out‐of‐hospital cardiac arrest (OHCA) is based on a set of interventions, all of which are intended to reduce anoxic brain injury and improve outcomes, including sedation, mechanical ventilation, circulatory optimization, and temperature control protocols.

ABSTRACT Background Determination of death by neurologic criteria (DNC) relies on clinical examination, provided no confounding conditions affect reliability. Current guidelines require patients to be free of confounders before neurologic testing but do not specify how these confounders should be assessed or managed.

Osteoarthritis: Epidemiology, Diagnosis, and Treatment
Osteoarthritis (OA) is a multifactorial degenerative joint disease and a leading cause of disability worldwide. This graphical abstract summarizes the epidemiology, diagnostic strategies, and therapeutic approaches of OA. OA development is driven by aging, metabolic dysregulation, and mechanical stress, leading to progressive joint degeneration ...

ABSTRACT Purpose To directly quantify respiration‐driven cerebrovascular resistance dynamics (CRD) using a gas‐free MRI framework based on the internal‐to‐external artery carotid flow ratio (ratio_Q). Theory and Methods Two independent datasets (n = 10 and n = 17) were used to evaluate repeatability and to compare breathing conditions.
