Fetal Akinesia/Hypokinesia and Arthrogryposis of Neuromuscular Origin: Etiologic Groups, Genetics, and Phenotypic Spectrum

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To provide a comprehensive clinical and genetic characterization of individuals with arthrogryposis multiplex congenita (AMC), focusing on the distribution of genetic etiologies across the neuromuscular spectrum and comparing myogenic and neurogenic subtypes. Methods A total of 105 individuals with AMC were clinically and genetically

Phenotyping Healthcare Use 2–3 Decades Before the First Multiple Sclerosis Demyelinating Event

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Phenotype hospital, physician, and emergency department (ED) visits by diagnoses and specialty up to 29 years pre‐multiple sclerosis (MS) onset versus a matched population without MS. Methods We identified people with MS (PwMS) using population‐based administrative data from Ontario, Canada (1991–2020).

Influence of Dystrophin Isoform Deficiency on Motor Development in Duchenne Muscular Dystrophy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective In Duchenne muscular dystrophy (DMD), lack of the shorter dystrophin isoforms Dp140 and Dp71 is associated with increased central nervous system (CNS) involvement. We aimed to investigate how CNS involvement affects motor development in young DMD boys.

Genetic Profile and Symptom Pattern Explain Variability of Deep Brain Stimulation Effect in Dystonia

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Bilateral globus pallidus pars interna deep brain stimulation (GPi‐DBS) is a recognized and effective treatment option for drug‐resistant dystonia patients. However, the clinical GPi‐DBS outcomes vary significantly. Herein, we explored the pre‐implant factors affecting GPi‐DBS effectiveness.

Active Seizures Predict Worse Instrumental Activities of Daily Living in Individuals With Normal Cognition and Dementia

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Cognitive disorders are common in older persons with seizures (PWS). Cognitive disorders are often associated with impaired Instrumental Activities of Daily Living (IADLs). However, the effects of seizures on IADLs remain unexplored.

Note on the bilinear difference equation with a delay

Mathematical methods in the applied sciences, 2018
A representation formula for the general solution to a higher‐order rational difference equation has been given recently in this journal. The formula was proved by the method of induction without giving any theoretical explanation related to it.

Quantum difference equation for Nakajima varieties

Inventiones Mathematicae, 2016
For an arbitrary Nakajima quiver variety X, we construct an analog of the quantum dynamical Weyl group acting in its equivariant K-theory. The correct generalization of the Weyl group here is the fundamental groupoid of a certain periodic locally finite ...

On the difference equation

Journal of Difference Equations and Applications, 2000
In this paper we study the boundedness and persistence, the oscillatory character and the asymptotic behavior of the positive solutions of the difference equation , where k∊{1,2,…}pi ∊0,∞i∊{0,…,k}Ai ∊0,∞i∊{0,…,k-1} and the initial conditions x -k ,…,x 0 are arbitrary positive numbers.
