Twelve‐month change in quantitative MRI calf muscle fat fraction in CMT1A predicts clinical change over 4 years

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Abstract Objective We measured clinical and quantitative MRI outcome measures in CMT1A to assess long‐term responsiveness, establish longitudinal validity and assess MRI as a bridging biomarker. Methods Twenty patients with CMT1A and 20 matched controls underwent MRI, myometry and clinical assessments up to four times over mean 4‐year follow‐up ...

Targeted Long‐Read Sequencing as a Single Assay Improves the Diagnosis of Spastic‐Ataxia Disorders

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The hereditary spastic‐ataxia spectrum disorders are a group of disabling neurological diseases. The traditional genetic testing pathway is complex, multistep and leaves many cases unsolved. We aim to streamline and improve this process using long‐read sequencing. Methods We developed a targeted long‐read sequencing strategy with the

Physics driven reduced order model for real time blood flow simulations [PDF]

open access: yesarXiv, 2019
Predictive modeling of blood flow and pressure have numerous applications ranging from non-invasive assessment of functional significance of disease to planning invasive procedures. While several such predictive modeling techniques have been proposed, their use in the clinic has been limited due in part to the significant time required to perform ...

Considering the Risks and Costs of Solid Organ Xenotransplantation

open access: yesAdvanced Biology, EarlyView.
This perspective discusses the rationale, risks, and costs of whole‐organ xenotransplantation. It considers alternative strategies to obviate the demand for transplants and optimize allotransplantation systems and practices that do not impose xenotransplantation's harms and risks, and whether they are the most ethical and effective means to increase ...

Numerical analysis of the pressure drop across highly-eccentric coronary stenoses: application to the calculation of the fractional flow reserve

open access: yesBioMedical Engineering OnLine, 2018
Background Fractional flow reverse (FFR) is the gold standard assessment of the hemodynamic significance of coronary stenoses. However, it requires the catheterization of the coronary artery to determine the pressure waveforms proximal and distal to the ...

Fractional flow reserve by computerized tomography and subsequent coronary revascularization [PDF]

open access: yes, 2017
AIMS: Fractional flow reserve by computerized tomography (FFR-CT) provides non-invasive functional assessment of the hemodynamic significance of coronary artery stenosis. We determined the FFR-CT values, receiver operator characteristic (ROC) curves, and
