Comparison of responses to isoproterenol and epinephrine during head-up tilt in suspected vasodepressor syncope [PDF]

, 1991
Head-up tilt is known to play an important role in establishing the diagnosis of vasodepressor syncope in patients with syncope of unknown etiology.1-5 Although passive head-up tilt alone may trigger a vasodepressor response, recent studies show that an ...

Efficacy of Fampridine on Refractory Optic Neuritis in Neuromyelitis Optica Spectrum Disorders

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Neuromyelitis optica spectrum disorders (NMOSD) usually occur with acute refractory optic neuritis (ON). However, there is a lack of efficacious treatments to improve recovery. Since fampridine has been found to improve the prognosis of multiple sclerosis (MS) and MS‐related ON, it is necessary to explore the efficacy of fampridine ...

Automatic Lesion Morphometrics Reliably Predict Sensorimotor Recovery After Spinal Cord Injury: A Longitudinal, Multicenter Neuroimaging Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To evaluate automatic magnetic resonance imaging (MRI)‐derived lesion morphometrics against manual measurements and their prognostic value for characterizing distinct acute to chronic neurological recovery trajectories after spinal cord injury (SCI). Methods We studied a retrospective, multicenter cohort of cervical and thoracolumbar

Four‐Year Cognitive Outcomes in Multiple Sclerosis: Associations With Lesion Myelin Integrity

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Cognitive impairment is prevalent in patients with multiple sclerosis (MS) but whether lesion myelin integrity influences future cognitive outcomes remains unclear. We investigated the relationship between baseline lesion myelin water fraction (MWF) and cognitive performance 4 years later.

The Utility of Head Up Tilt Test with Video Electroencephalography in Children with Recurrent Loss of Consciousness

, 2013
Aim: We aimed to detect the utility of head up tilt test with video electroencephalography (EEG) in children with unexplained, recurrent loss of consciousness episodes. Method: Video EEG were recorded during the head up tilt test. The test was terminated

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

Advanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Hemodynamic Response to the Head-Up Tilt Test in Patients With Syncope as a Predictor of the Test Outcome: A Meta-Analysis Approach

Frontiers in Physiology, 2019
Aim: The paper presents a meta-analysis of studies comparing hemodynamic parameters: heart rate (HR), systolic blood pressure (sBP), diastolic blood pressure (dBP), and stroke volume (SV) measured during head-up tilt table test (HUTT) in patients with ...
