RESUMO

Introducción: El avance de las nuevas tecnologías ha contribuido a elevar las opciones de interacción de las personas con los productos a partir del empleo de las interfaces de usuario. El uso de dispositivos con interfaces de usuario, diseñados como soportes orientados a la rehabilitación neurológica, puede potenciar y diversificar este proceso en contextos intra hospitalarios y extra hospitalarios. Objetivo: Identificar los criterios que determinan la aceptabilidad de estos dispositivos en la rehabilitación motora de pacientes con enfermedades neurológicas. Métodos: La muestra estuvo conformada por 31 pacientes del Instituto de Neurología y Neurocirugía tributarios de rehabilitación motora y un grupo control (N = 62) con sujetos sanos. Se construyó un cuestionario con 32 ítems que exploran los criterios de aceptabilidad de las interfaces de usuario. La versión final del cuestionario se obtuvo de la evaluación según criterio de expertos y el cálculo de la consistencia interna mediante el alfa de Cronbach. A los valores obtenidos durante la aplicación del cuestionario se les realizó un análisis factorial usando como método de rotación el varimax normalizado. El criterio para extracción de factores fue el método de autovalores de Scree. Resultados: La aceptabilidad del uso de dispositivos con interfaces de usuario está condicionada por tres categorías fundamentales: seguridad, expectativas y facilidad de asimilación. Conclusiones: La aceptabilidad de estos dispositivos depende de garantizar la seguridad en su uso, cumplir con las expectativas de una rehabilitación autónoma y hacer evidente y viable su facilidad de asimilación. Contar con estos criterios redunda en la obtención de requerimientos ergonómicos para el diseño de estos dispositivos(AU)


Introduction: The advance of new technologies has contributed to raising the interaction options of people with products from the use of user interfaces. The use of devices with user interfaces, designed as supports aimed at neurological rehabilitation, can enhance and diversify this process in intra-hospital and extra-hospital contexts. Objective: Identify the criteria that determine the acceptability of these devices in the motor rehabilitation of patients with neurological diseases. Methods: The sample consisted of 31 patients from the Institute of Neurology and Neurosurgery who needed motor rehabilitation and a control group (N = 62) with healthy individuals. A questionnaire with 32 items was created and it explored the acceptability criteria of user interfaces. The final version of the questionnaire was obtained from the evaluation according to expert criteria and the calculation of internal consistency using Cronbach's alpha. To the values obtained during the application of the questionnaire, there was performed a factor analysis using the normalized varimax as the rotation method. The criterion for factor extraction was the Scree eigenvalue method. Results: The acceptability of the use of devices with user interfaces is conditioned by three fundamental categories: security, expectations and ease of assimilation. Conclusions: The acceptability of these devices depends on guaranteeing safety in their use, meeting the expectations of an autonomous rehabilitation and making evident and viable their ease of assimilation. Having these criteria, results in obtaining ergonomic requirements for the design of these devices(AU)

RESUMO

UNLABELLED: Huntington's disease (HD) is an autosomal dominant, progressive neurodegenerative disorder, caused by an expanded trinucleotide CAG sequence of the huntingtin (Htt) gene, which encodes a stretch of glutamines in the Htt protein. The mechanisms of neurodegeneration associated with the accumulation of Htt aggregates still remains unclear. OBJECTIVES: To determine oxidative stress biomarkers in HD patients and their relationship with clinical, demographic and neuroimaging parameters. DESIGN AND METHODS: Fourteen patients and 39 controls paired by age and sex participated in this study. Oxidative damage was assayed in blood by measuring malondialdehyde (MDA) and advanced oxidative protein products (AOPPs). Antioxidant status was determined by activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione reductase (GR), reduced glutathione (GSH), protein thiols and total antioxidant capacity (FRAP). The Unified Huntington Disease Rating Scale (UHDRS) and neuroimaging studies were also employed. RESULTS: MDA, AOPP and GPx were significantly increased in HD patients with respect to the control group, while GR activity was decreased. FRAP correlated with age of disease onset, AOPP with motor severity (UHDRS score), age of patients and age of disease onset. Caudate atrophy was associated with lower plasma concentrations of GSH. CONCLUSIONS: These findings point to a redox imbalance in HD patients. GR activity could be a potential biomarker for symptom onset in asymptomatic gene carriers, while plasmatic GSH could be useful in monitoring the progression of neurodegeneration - as an expression of caudate atrophy - during the course of the disease.

RESUMO

La atrofia multisistémica constituye un trastorno neurodegenerativo esporádico de etiología no precisada que se caracteriza por parkinsonismo, trastornos cerebelosos, disfunción autonómica y piramidalismo; los hallazgos patológicos comprenden pérdida celular y gliosis en las neuronas estriatonígricas, olivopontocerebelosas y autonómicas; y la presencia de inclusiones intracitoplasmáticas oligodendrogliales y neuronales, ubiquitina, tau y alfasinucleína positivas. Afecta tanto a hombres como a mujeres, con inicio en la sexta década de la vida como promedio y una prevalencia de 4/100 000. Se presentaron los últimos criterios diagnósticos de atrofia multisistémica y el caso clínico de un paciente de 65 años con un cuadro progresivo, de 4 años de evolución, ataxia cerebelosa progresiva, síndrome rígido acinético, disfunción autonómica, signos piramidales y mala respuesta a la levodopa, con imágenes de resonancia magnética que muestran atrofia de vermis, hemisferios cerebelosos, tallo cerebral (puente) e hipointensidad de ambas regiones putaminales en t2. Se concluyó el caso con el diagnóstico de atrofia multisistémica tipo C


The multisystem atrophy is a sporadic neurodegenerative disorder of unknown origin characterized by parkinsonism, cerebellar disorders, autonomic dysfunction and pyramidal disease, provoked by a cellular loss and gliosis in the nigrostriatal, olivopontocerebellar and autonomic neurons and the presence of oligodendroglia and neuronal intracytoplasmic positive inclusions, ubiquitin, tau and alpha-sinuclein affecting men and women starting as average during the sixth decade of life and a prevalence of 4/100 000. The last diagnostic criteria of multisystem atrophy were showed as well as the clinical case of a patient aged 65 with a progressive picture of 4 years of evolution, progressive cerebellar ataxia, a rigid akinetic syndrome autonomic dysfunction, pyramidal signs and a poor response to levodopa with magnetic resonance images showing vermis atrophy, cerebellar hemispheres, cerebral stem (bridge) and hipointensity of both putamen regions in T2. We conclude that case was diagnosed with type C multisystem atrophy
