ABSTRACT
La lucha epidemiológica contra la pandemia COVID-19 ha incluido medidas sociales como el confinamiento y el cierre de actividades laborales y académicas. A consecuencia, tareas que se llevaban a cabo en el contexto presencial debieron ser ejecutadas desde los hogares, adoptando estrategias como el teletrabajo y la educación virtual, haciendo necesario el uso de herramientas como ordenadores y laptops. De allí que las personas han incrementado la exposición a las pantallas de dispositivos electrónicos, como son computadoras y laptops, trayendo como consecuencia afectaciones en la salud visual de las personas tales como el síndrome visual informático (SVI). Se realizó un estudio transversal con el objetivo de determinar la afectación por SVI en la población peruana y su relación con la exposición prolongada a DEV, generada a raíz de las medidas sociales de enfrentamiento a la pandemia de COVID-19. El tiempo promedio en que los sujetos de nuestro estudio usaron DEV dentro de los hogares se acrecentó un 120%, es decir 4,26±2,36 horas diarias adicionales al comparar con el año anterior a la pandemia COVID-19. La adopción masiva de actividades como el teletrabajo y la educación virtual podrían explicar el hecho que los grupos de empleados/patronos y estudiantes fueron los mayores usuarios de DEV, con 10,41 y 9,32 horas diarias. De acuerdo a los hallazgos obtenidos, es estadísticamente válido afirmar que las medidas sociales para enfrentar la pandemia COVID-19 indujeron al aumento en la prevalencia de SVI en los pobladores peruanos (p<0,001). En la actual investigación, la proporción de individuos que manifestaron SVI pasó de 38 a 64%, antes y durante la aplicación de las medidas, respectivamente(AU)
The epidemiological fight against the COVID-19 pandemic has included social measures such as confinement and the closure of work and academic activities. As a consequence, tasks that were carried out in the face-to-face context had to be carried out from homes, adopting strategies such as teleworking and virtual education, requiring the use of tools such as computers and laptops. Hence, people have increased exposure to the screens of electronic devices, such as computers and laptops, resulting in effects on people's visual health such as computer vision syndrome (SVI). A cross-sectional study was carried out in order to determine the affectation by SVI in the Peruvian population and its relationship with prolonged exposure to DEV, generated as a result of social measures to cope with the COVID-19 pandemic. The average time in which the subjects in our study used DEV within homes increased by 120%, that is, 4.26 ± 2.36 additional daily hours when compared to the year before the COVID-19 pandemic. The massive adoption of activities such as teleworking and virtual education could explain the fact that groups of employees / employers and students were the largest users of DEV, with 10.41 and 9.32 hours per day. According to the findings obtained, it is statistically valid to affirm that the social measures to face the COVID-19 pandemic induced an increase in the prevalence of SVI in the Peruvian population (p <0.001). In the current investigation, the proportion of individuals who manifested SVI went from 38 to 64%, before and during the application of the measures, respectively(AU)

As doenças cerebrovasculares apresentam altas incidências no Brasil sendo a hemiparesia uma das sequelas mais incapacitantes. A marcha hemiparética é caracterizada pela baixa velocidade, padrõesassimétricos, déficit de equilíbrio, propriocepção, força muscular e um alto custo energético. O treino da deambulação em indivíduos vitimados da Doença Encefálica Vascular (DEV) é um dos primeiros alvos da reabilitação. O objetivo desse estudo foi avaliar os benefícios trazidos a partir de uma intervenção fisioterapêutica através da utilização de exercícios aeróbicos voltados para capacitação funcional. Secundariamente, a perda ou redução da capacidade física geram um decréscimo na intensidade e frequência da prática de atividades físicas que envolvam ações da vida diária, lazer (esporte) ou trabalho. Recuperar a habilidade de locomover-se está entre uma das maiores preocupações de sujeitos com hemiplegia/hemiparesia, uma vez que a locomoção permite independência e tem um impacto direto no retorno ao lar. Este estudo foi desenvolvido por intermédio do modelo experimental de pesquisa que permitiu avaliar a capacidade funcional da marcha através do teste de caminhada de seis minutos. A velocidade média e a distância percorrida foram os parâmetros selecionados e analisados com auxílio dos recursos da estatística descritiva, sendo estabelecido o índice de significância (α=0,05). Foi observado como resultados valores significativos da distância percorrida e da velocidade média dos participantes, indicando melhora no ganho funcional da marcha destes indivíduos.
Cerebrovascular diseases have high incidence in Brazil and the hemiparesis is one of the most disabling sequelae. The hemiparetic gait is characterized by low speed, asymmetric movement, deficit of balance, proprioception, muscle strength and a high energy cost. The practice of walking in individuals victims of stroke is one of the first targets of rehabilitation. The purpose of this study was to evaluate the benefits of a physiotherapy intervention using aerobic exercises focused on functional capacity. In the second hand, the lost or reduction of physical capacity generate a decrease in intensity and frequency of physical activities that involve actions of daily living, leisure (sports) or work. Recover the ability to move is one of the major concerns among people with hemiplegia / hemiparesis, since locomotion allows independence and has direct impact returning home. This study was developed through the experimental design or model of research which allowed us to evaluate the functional capacity of the gait applying the test of six-minute walk. The average speed and the distance were the parameters selected and analyzed with the help of the descriptive statistical methods, and was set the significance level (α = 0.05). As results, was observed significant amounts of distance traveled and average speed of the participants, indicating an improvement in functional acquisition on the gait of these individuals.

Duck enteritis virus (DEV) is a herpesvirus that causes an acute, contagious and fatal disease. In the present article, the DEV UL4 gene was cloned and sequenced from a vaccine virus. A degenerate oligonucleotide primer for the consensus site of herpesvirus UL3 gene and a specific primer located in UL5 were used in the polymerase chain reaction (PCR) to amplify a DNA product 2 086 bp in size. DNA sequence analysis revealed that a 714 bp open reading frame (ORF) of DEV encoding a 237 amino acid polypeptide is homologous to the family of herpesvirus UL4 proteins and therefore has been characterized as a DEV UL4 gene. Alignment of the DEV UL4 protein sequence with those of other alphaherpesviruses showed that 10 amino acid residues are completely conserved. Phylogenetic tree analysis showed that the seventeen alphaherpesviruses viruses analyzed were classified into four large groups, and the duck enteritis virus branched separately, closely related to the Mardiviruses group comprising Gallid herpesvirus 2 (GaHV-2), Gallid herpesvirus 3 (GaHV-3) and Meleagrid herpesvirus 1 (MeHV-1). The present study showed that the evolutionary relationship of the UL4 protein could be used for classification of alphaherpesviruses.
