RESUMO

ObjectiveTo verify the impact and findings of the COVID-19 patients group that underwent brain scans in comparison to the group which only chest CT was performed. Method876 suspected COVID-19 patients and a subsample of 232 cases with confirmed COVID-19 who underwent brain CT/MRI scan (n=35) or only chest CT (n=197) in two radiology departments, were evaluated. Results5.59% of all suspected COVID-19 patients found had brain scans and 98.74% chest CT. There was a statistically significant difference with associations regarding the COVID-19 brain scan group for: admission to ICU, greater severity of lung injuries, the use of mechanical ventilator, seizure, sepsis, and stroke and statistical tendency for chronic renal failure and systemic arterial hypertension. 40.0% of COVID-19 patients from the brain scan group were abnormal on brain CT and/or brain MRI. 22.9% cases with any kind of bleeding or microbleeding, 8.6% with restricted diffusion lesions. One ischemic stroke case was associated with irregularity at M1 segment of the right middle cerebral artery. There was a case of left facial nerve palsy with enhancement of left geniculate ganglia. An analyse of the olfactory bulbs was possible in 12 brain MRIs and 100% had enhancement and/or microbleeding. There was no statistical difference regarding death (9.1% versus 5.2%). In conclusionthe COVID-19 patients group on which brain CT and/or MRI needed to be performed was statically associated with the more severe COVID-19 disease, an indication to ICU, a more severe form of lung disease, use of mechanical ventilator, seizure, sepsis and stroke. Less than half of patients had abnormal brain imaging scans with all of them showing vascular brain injury lesion, being more frequently microbleeding or bleeding, followed by restricted diffusion lesions. All the olfactory bulbs evaluated showed injury by vascular phenomenon, probably methahemoglobine by microbleeding or microthrombus and/or abnormal enhancement

RESUMO

Objective. The objective of this study was to evaluate the effects of a protocol of aquatic exercises in postural control of elderly subjects with overweight and the influence of body mass and body mass index in variables of the center of pressure. Method. Each participant was positioned on the force platform, without shoes, feet apart on the same alignment of the upper limbs along the body. For the collection, the subjects were instructed to stay on in bipedal support on the force platform with eyes fixed on the bright spot for 60s. Results. Results indicated a notable difference in the variables root mean square-mediolateral and COP area after aquatic exercise practice. However, visual condition analyzed indicates significant differences in the variables root mean square-anteroposterior and speed anteroposterior. Conclusion. Aquatic exercise had positive effects when analyzing the sensory condition suggesting maintenance of postural control. However, when analyzed post aquatic exercise in closed eyes condition and the interaction effects of visual condition did not improve postural stability. In obese elderly, body mass index resulted in a functional adaptation in control of upright stance, suggesting that the balance was preserved in the population studied


Objetivo. El objetivo de este estudio fue evaluar los efectos de un protocolo de ejercicios acuáticos en el control postural de sujetos de edad avanzada con exceso de peso y la influencia de masa corporal y el índice de masa corporal en las variables del centro de presiones. Método. Cada participante se posicionó en la plataforma de fuerza sin zapatos, los pies separados con la misma alineación de las extremidades superiores a lo largo del cuerpo. Para el análisis, los sujetos fueron instruidos para permanecer en apoyo bípedo sobre la plataforma de fuerza con los ojos fijos en un punto brillante durante 60 segundos. Resultados. Los resultados indicaron una diferencia notable en las variables: Media Cuadrática-Mediolateral y el Área descrita por el desplazamiento del centro de presiones, después de la práctica de ejercicio acuático. Sin embargo, la condición visual analizada indica diferencias significativas en las variables: Media Cuadrática Anteroposterior y Velocidad Anteroposterior. Conclusión. El ejercicio acuático tuvo efectos positivos en el análisis de la condición sensorial sugiriendo el mantenimiento del control postural. Sin embargo, cuando se analizan la condición de ojo cerrado tras el ejercicio acuático y los efectos de la interacción de la condición visual no mejoró la estabilidad postural. En obesos de edad avanzada, el índice de masa corporal resultó en una adaptación funcional en el control de la postura vertical, lo que sugiere que el equilibrio se conservó en la población estudiada


Objetivo. O objetivo deste estudo foi avaliar os efeitos do protocolo de exercícios aquáticos no controle postural de idosos com excesso de peso, e a influência de variáveis de massa corporal e índice de massa corporal no centro de pressão. Método. Cada participante foi posicionado sobre a plataforma de força, sem sapatos, pés alinhados, braços ao longo do corpo. Durante a coleta, os indivíduos foram orientados a permanecer sobre a plataforma de força, com os olhos fixos no ponto brilhante durante 60 segundos. Resultados. Os resultados indicaram uma diferença significativa nas variáveis: área do centro de pressão e média quadrática-mediolateral, após a prática de exercício aquático. No entanto, a análise da condição visual sugere diferenças significativas nas variáveis: média quadrática anteroposterior e velocidade anteroposterior. Conclusão. Os exercícios aquáticos tiveram efeitos positivos sobre a análise sugerido pela condição da manutenção do controle postural. No entanto, quando analisados em condição de olho fechado após o exercício aquático e os efeitos da interação da condição visual, não melhoram a estabilidade postural. Em obesos idosos, o índice de massa corporal resultou numa adaptação funcional para controlar a posição vertical, o que sugere que o equilíbrio foi mantido na população estudada
