A relação entre transtorno da insônia e funções executivas em adultos

The insomnia disorder is defined as a difficulty initiating or maintaining sleep or waking up earlier than expected unable to return to sleep, followed by a feeling of nonrestorative and poor quality sleep, present for at least three months, with consequences on daytime functioning. Studies have shown that insomnia affects cognitive function, especially executive functions. However, researches that sought to investigate the relationship between primary insomnia and executive functioning were quite inconsistent from a methodological point of view, especially in regard to the variability of the used methods, the heterogeneity of diagnostic criteria for insomnia and the control of sleep altering drugs. In this sense, the present study aimed to investigate the relationship between insomnia and executive functions in adults. The participants were 29 people, from both genders, aged 20-55 years old. Participants were divided into three groups, one composed of 10 people with primary insomnia who used sleep medication (GIM), nine people with primary insomnia who did not use medication (GInM) and 10 healthy people who composed the control group (CG). The research was conducted in two stages. The first one involved a diagnostic evaluation for insomnia disorder through a clinical interview and the application of the following protocols: the Athens Insomnia Scale, the Insomnia Severity Index, Sleep Journal (for 14 days), Pittsburgh Sleep Quality Index (PSQI), the Stanford Sleepiness Test, depression and anxiety Beck inventories, and Lipp’s Iventory of stress symptoms for adults. After this stage, the evaluation of executive functions was performed by applying a battery of neuropsychological tests composed by the following tests: Wisconsin, Stoop Test, Colored trails Test, the Tower of London Test, Iowa Gambling Task (IGT) and WAIS III subtest digit span, which measured selective attention, inhibitory control, cognitive flexibility, planning, problem solving, decision making and working memory, respectively. The results showed that insomniacs (GIM and GInM) showed higher sleep latency, shorter sleep duration and lower sleep efficiency compared to the CG. In regard to the performance in executive functions, no statistically significant difference between groups was observed in the evaluated modalities. However, the data show evidence that, compared to GInM and GC, the performance of GIM was lower on tasks that required quick responses and changes in attention focus. On the other hand, GInM, when compared to GIM and GC, showed a better performance on tasks involving cognitive flexibility. Furthermore, impaired sleep measures were correlated with the worst performance of insomniacs in all components evaluated. In conclusion, people with the insomnia disorder showed a performance similar to healthy people’s in components of the executive functioning. Thus, one can infer that there is a relationship between primary insomnia and executive functions in adults.

Efeito tardio do kinesio taping na função do membro inferior e no desempenho neuromuscular do quadríceps femoral de mulheres saudáveis: ensaio clínico e randomizado

Introduction: Kinesio Taping (KT) has been used in healthy people to improve neuromuscular performance, however, few studies have evaluated its chronic effects, despite being suggested. Objective: To analyze the chronic effects of KT on neuromuscular performance of the quadriceps, the oscillation of the center of pressure and lower limb function in healthy women. Methods: blinded, randomized, controlled trial, composed of 60 women (mean age 21.9 ± 3.3 years and BMI 22.3 ± 2.2 kg / m2) submitted to the evaluation of oscillation of the center of pressure through the baropodometry, the lower limb function by the hop test, isokinetic knee performance, the electromyographic activity of the vastus lateralis (VL) and joint position sense of the knee (JPS). Then, participants were randomly divided into three groups of twenty: control - did not apply the KT; placebo - application of KT without tension on the quadriceps; Kinesio Taping - application of KT with tension in the same muscle group. The evaluations were conducted in five moments: prior to application of KT, immediately after the application, 24h, 48h after application and 24 hours after its removal (72h). SPSS 20.0 was used for statistical analysis. The KS test was used to verify the data normality, the Levene test for homogeneity of variances and a mixed-model ANOVA 3x5 to check intra and inter-group differences. Results: there was no difference in peak torque, the power, nor the electromyographic activity or SPA (p> 0.05) between groups. The displacement speed of center of pressure reduced immediately after the application on kinesio taping group (p <0.001), but with no differences between the groups (p = 0.28). There was a reduction in the time of peak torque among the three groups in the evaluations after KT application (p <0.001) and an increase in single hop in all groups (p <0.001), but with no differences between them. Conclusion: KT can not change, in a chronic way, the lower limb function, the oscillation of the center of pressure, the isokinetic performance, the JPS of the knee and the electromyographic activity of VL muscle in healthy women.

Efeitos do Kinesio Taping® sobre os marcadores clínicos indiretos de dano muscular induzido pelo exercício excêntrico: ensaio clínico randomizado

Objective: analyze the effect of Kinesio Taping (KT) on the indirect clinical markers of muscle damage induced by eccentric exercises in the elbow flexors in healthy individuals. Materials and methods: It is a randomized controlled trial involving sixty volunteers at age group between 18 and 28 years randomly selected. The sample into three groups with twenty participants: control group (CG) – eccentric protocol without KT, KT group – eccentric with tensioned KT, placebo group – eccentric protocol KT with no tension. The evaluations took place at four moments; the first one was the basis line (AV1), after the second protocol (AV2) and the following two groups 24 (AV3) and 48 hours (AV4) after the intervention protocol. The muscle damage was induced by sixteen maximum eccentric contractions of the elbow flexors from the non-dominant limb, divided in two sets of eight repetitions, at 60º/s, with two minutes interval. The variables analyzed were: the joint amplitude in rest, the level of pain, the joint position sense (JPS) followed of isokinetic checking with electromyographic sign capitation. These data were analyzed in software SPSS 20.0. The normality was identified by Kolmogorov-Smimov examination and then, being used the ANOVA mixed model with significance of 5%. Outcomes: a decrease was observed at joint amplitude moreover, an immediate increase of pain wich increased after 24 and remained until 48 hours at all groups searched. There was not difference at the JPS. The variables peak torque, average peak torque, total work and mean power mean reduced until 48 hours after muscle lesion in all groups. Among the groups, there was no difference in EMG values and for any of the variables. Conclusion: The KT did not influence at the indirect clinical markers of muscle lesion induced by eccentric exercises in the elbow flexors in healthy people.

Programa Agente jovem em Arez/RN: juventude e violação de direitos

This paper proposes discusses the theme of the youth and of the violation of rights in the context of the Young Agent Program developed in the local authority of Arez/RN, sugar cane region of the Brazilian northeast. We take like empirical reference, the young people in the age group from 15 to 17 years old that were participating of the activities of the Program, in the period of April to July of 2008. Objectives of this study were constituted, economical-partner apprehended the conditions and cultural of the young participants of the Young Agent Program, in the context of violations of rights; as well as the analysis of the limits and means, of the bases theoretician-politician, methodological and of the activities developed in the Program. In the persecution of the objectives we use like methodological instrumental the observation, activities in group with the focal group technique and the application of semi-structured interviews. As result, we notice that the violation of rights of the young persons inserted in the Young Agent Program of Arez sets itself up as reflex of the multiple determinations of the social question, inherent in the capitalist society, specified in the context of the poverty and of the social unequality that they acquire visibility in the hunger, in the unemployment / menial job, in the precarious dwelling, in the low schooling, for lack of leisure, in the violence between others. The approximations systematized in this healthy work relevant for the Unveiling of the reality of the Brazilian youth, specifically of Arez young people, in such a way that they come to subsidize future inquiries, are eaten by me also it promotes the discussion around the way like the Social Politics Programs they are implemented and driven in the capitalist society, in its neoliberal format, where the focusing and the selectivity is put on top to the detriment of the universal access of the democratic rights. So, the great challenge that is put for the XXI century is to cause to the voices from these which they do and this which build this country, in the continuous and tireless search of the rights realization in the struggle against the barbarism installed in the capitalist societycapitalista
