Investigação do papel modulador do Haloperidol sobre os níveis de proteínas relacionadas à plasticidade e preferência por objetos novos em camudongos

Dopamine (DA) is known to regulate both sleep and memory formations, while sleep plays a critical role in the consolidation of different types of memories. We believe that pharmacological manipulation of dopaminergic pathways might disrupt the sleep-wake cycle, leading to mnemonic deficits, which can be observed in both behavioral and molecular levels. Therefore, here we investigated how systemic injections of haloperidol (0.3 mg/kg), immediately after training in dark and light periods, affects learning assessed in the novel object preference test (NOPT) in mice. We also investigated the hippocampal levels of the plasticity-related proteins Zif-268, brain-derived neurotrophic factor (BDNF) and phosphorylated Ca2+/calmodulin-dependent protein kinases II (CaMKII-P) in non-exposed (naïve), vehicle-injected controls and haloperidol-treated mice at 3, 6 and 12 hours after training in the light period. Haloperidol administration during the light period led to a subsequent impairment in the NOPT. In contrast, preference was not observed during the dark period neither in mice injected with haloperidol, nor in vehicle-injected animals. A partial increase of CaMKII-P in the hippocampal field CA3 of vehicle-injected mice was detected at 3h. Haloperidol-treated mice showed a significant decrease in the dentate gyrus of CaMKII-P levels at 3, 6 and 12h; of Zif-268 levels at 6h, and of BDNF levels at 12h after training. Since the mnemonic effects of haloperidol were only observed in the light period when animals tend to sleep, we suggest that these effects are related to REM sleep disruption after haloperidol injection

OBALUAIÊ: um estudo sobre o estigma no convívio com o HIV/Aids em terreiros de Umbanda na cidade de Fortaleza-Ceará

The tradition and living in African-Brazilian religious spaces, called yards, reveal how dynamic the reproduction and exchange of knowledge are, and that through their worldview, reveal ways of dealing with health and disease. The yards are culturally rich territories, in which people shape concepts, practices, and beliefs about health, disease and forms of healing, passed on from generation to generation through oral tradition. With the advent of HIV/AIDS from the 80s, a new challenge is established in the community of the yards and in the individual trajectories of people affected by the disease, who since an early age participate in this religious practice. The objective of this research is the analysis on the stigma in living with HIV/AIDS in yards of Umbanda in Fortaleza-Ceará, considering the (re)production of social dramas experienced by the community in question. During the investigation we adopted two basic parameters: the first one considers the understanding of the reproduction of stigma (or deteriorated identity) in relation to HIV/AIDS in its socio-historical dimension and its effects in the investigated context (Goffman, 1988). And the second one refers to the creation and reproduction of social dramas as a social experience carried through learning, handling and symbolic performance, which is reproduced in four stages: rupture, crisis, corrective action and reintegration (Turner, 1971)

Representações sociais de discentes sobre universidade: um estudo psicossocial entre ingressantes do vestibular e da seleção ProUni

Demand for access to higher education to put in test the education Brazilian system in view of the surplus of selective processes of public universities, people without option to pay their studies at this education level. In this context, it has arisen the University for All(Universidade para Todos)Program, the ProUni, from Ministry of Education - MEC, created by the Federal Government in 2004, and that it aims the granting of full and partial scholarships in private higher education institutions, graduate courses in sequential specific training, low-income Brazilians students who do not have higher-level degree. Created by the Provisional Measure No 213/2004 and institutionalized by Law No. 11096 of January 13, 2005, the ProUni offers, however, the exemption of some taxes to those institutions that join the program. This is one of the privileged time for the study of Social Representations by offering the researcher, a living laboratory, natural environment, the confrontation between the established and new. In time like this people are challenged to incorporate the new system to the pre-existing one, aiming it through a strangeness of what was so familiar. It is through this game of social forces that we developed the present study with 196 entering higher education, of these are 116 of selective vestibular system and 80 of the ProUni selective system. We opt by the procedures for data collection in order to have access to the circulating senses, in addition to the streamlined responses. With foundation in Abric, we perform the test the Free Association of Words, then analysed by the software and by EVOC Content of the type theme as Bardin. Besides, we require of the subjects, a writing on the study object university later analysed by the software ALCESTE. The results point out to a representation strongly rooted in social factors such as more traditional socio-cultural elements: the beliefs, values, the symbols. It is unique in both groups of subjects: among those entering by the selective ProUni system, there was a stronger anchor in that it does not make inquiries about the program. At the same time, there is a stronger presence of objectivation, entering the selective vestibular system in order that they explained with a value judgement on the programme. It is suggested further studies considering the embryonic state of social representation, as recent as the social purpose that triggered. It would be relevant even the replication of the same research with other people in order to strengthen the power of the theorising of empiria available

Representações sociais sobre a prática do cuidado para enfermeiros da saúde indígena: um estudo transcultural

The desire to research on this subject arisen from the experience as nursing in the indigenous health, where I observed that many professionals from all regions of Brazil chose to work within this zone. It was notorious the nurse s difficult to settle in only one place for a long length of time. Probably due to health care in indigenous zones happens from a cultural confront. This confront materialize because both sides are imbued with their own culture: in one hand the nurse professional with its scientific knownledgment on the other the indigenous with their rituals and peculiars habits. In this context nurses should delineate and negotiate the reality through symbolic representations of life, and then make questions on the new reality. In this way, this study set out with the aim of apprehends the nurse s social representations of transcultural care in indigenous health. This knownledgment is important to avoid possible conflicts, shocks, difficulties and health care incongruence within this context. The data collect was carried out on a range of non structured interview guided by a pre-elaborated questionnaire with four questions and a hand drawing related to nurse s health care in the indigenous health. This research had a sample of 17 nurses from the Indigenous Sanitary District of Manaus in the Amazon State. To interpret data we used the Discourse of the Collective Subject, which findings were presented in three chapters: characterization of participants, discussion on themes prevalent in discourse; social representation of nursing care through infographics. The analysis revealed that the care in the indigenous health is challenging because the native people imbued in its world are perceived and processed according to the nurse s cultural lens, leading to materialize of some strangeness and adaptation difficulties, especially in the first contacts. The Social Representation on nursing practice, in many cases, is projected and contrived on the basis of scattered believes and on perception derived from common sense. The findings shows that representions are essential to mitigating the initial strangeness and help nurses to better situate themselves in the new universe. The nurse s practice in the indigenous health care should merge into each other. From the Social Representations is possible to perceive that assimilation, also comprehension on indigenous health system and its traditional knowledge are important to developing strategies to improve access and quality of care for indigenous peoples. After analysis the nurse s discourses and drawings, it is possible to represent the nurse s practice in the indigenous health as anthropophagism, since nurses should literally consuming its patients culture, digesting it and seize it as means to provide culturally congruent care. We highlight the urgent need for preparation and training of professionals to work more effectively with indigenous peoples

Qualidade da assistência e o conhecimento sobre o direito à saúde das pessoas com úlcera venosa crônica

The study aimed to identify the quality of care and knowledge of health rights of people with chronic venous ulcers (VU) in Brasilian National Health Care System (SUS). It is a cross-sectional study, with quantitative approach, performed at the University Hospital Onofre Lopes (HUOL). The study was approved by the Ethics Committee of HUOL (CAAE nº 0148.0.051.000-10). The sample by accessibility was composed for 30 people with VU treated at the outpatient surgical clinic of HUOL. For data collection we used a structured questionnaire composed of two parts: sociodemographic characteristics and of health, of care and the clinical course of VU; and knowledge of people with VU about the rights of health. The results were processed using SPSS 15.0 and analyzed by descriptive statistics. Given the characterizations sociodemographic and health presented, we identified a clientele of users with VU predominantly female (76,7%), aged from 60 years (66,7%), married/ stable union (60,0%), low education level (83,3%), family income lower than a minimum wage (73,3%), unemployeds and with chronic diseases (53,3%), sleep greater than or equal to 6 hours (76,7%) and were not alcoholics or smokers (93,3%). In relation to clinical conditions, were shown the presence of one or more relapses of VU (73,3%), predominance of granulation tissue/epithelialization in the bed of VU (60,0%), exudate serosanguineous (43,3%), in quantity medium/large (60,0%), with no predominance of presence or absence of odor (50,0%), all patients with tissue loss in grade III / IV, no signs of infection (73,3%) and presence of intense pain (50,0%). In the last 30 days the main venue of achievement of dressing was the HUOL (100,0%), the main compression therapy used was the Unna boot (60,0%) and on inability to perform the dressing on the unit were the own patients who made the exchange at home (40,0%). The majority of respondents listed out more positive factors associated with quality of care (56,7%) were satisfied with the care of SUS (76,7%), claimed to have knowledge about their rights (70,0%), but at the same time did not know the meaning of the acronym SUS (90,0%) and classified their level of information as inappropriate (70,0%). We realize that people with VU identified as good the quality of care and demonstrated inadequate knowledge about their rights to health in the SUS, but showed interest in acquiring more information. The basic rights to entry in the SUS are constitutionally guaranteed and need to be disseminated in order to make them known to the population, so it can be implemented and ensured a greater resolution assistance in treating this type of injury

Cuidado de enfermagem ao potencial doador de órgãos em morte encefálica: uma reflexão sobre a prática

Despite of the technological advances that favor the transplant process, there are issues of effectiveness of care necessary for the maintenance of potential organ donors with brain death, which contribute to the no realization of transplants of organs and tissues of these patients. It is presupposed that the problems could be related to perceptions and understandings that the professionals of the units of internment have about the care required by the diagnosis of brain death. The aim of this study was to understand the meaning of the nursing care of the potential organ donor with brain death to the nursing staff. Descriptive study with qualitative approach guided by Action Science Theory and the critic-reflexive research methodology accomplished with five nurses and 19 nursing technicians from Operative Rehabilitation Center in a public hospital at Natal / RN, Brazil, between March and May 2013. Data were collected through semi-structured interviews with individual reflection about the care and through group interview, after approval by the Ethics and Research Committee, CAAE No.: 04255612.7.0000.5537. The analysis was performed in a thematic way according to Bardin. During the group meeting the participants were driven in a discussion about the need for change and how to perform them. The results indicate that the professionals actions are consistent with those required for maintenance of potential organ donors, although the material and human resources are not adequate. That situation leads the professionals to develop a meaning of care as one labor more, demanding more than they can give. They express beliefs and feelings concerning the hope that their care brings a greater good that is to save lives. The reflection for a possible change of action was difficult to accomplish due to professionals not to be able to self evaluate, what lead to direct your changes suggestions for other team members. It is concluded that the care provided to these patients is a difficult care, evidenced by suffering both death situation of the person cared and pain of their families, as the dehumanizing conditions of work, helping themselves to keep distance from patients to not suffer so much. The knowledge impregnated in their act, are scientific, ethical, aesthetic and personal kind with a predominance of the scientific followed by the personal. The study was also relevant to the practice of nursing in maintaining the potential donor, in that it allowed the identification of the knowledge used by nurses in their care practice and the meaning understanding of the professionals on the care provided, as a good action that brings satisfaction when the transplanting is executed. Other experiences are suggested with the critic-reflexive research methodology, both in research as in teaching nursing

Abordando as relações ctsa no ensino da química a partir das crenças e atitudes de licenciandos: uma experiência ormativa no Sertão Nordestino

Este estudio investigó las actitudes y creencias de los estudiantes universitarios en Ciencias Químicas por la Universidad de Río Grande do Norte (UERN) como un paso hacia la elaboración de una propuesta de material didáctico para el estudio de las relaciones CTSA en la licenciatura en química. Para el conocimiento de las actitudes y creencias fue utilizado dos instrumentos (Escala Likert y un cuestionario), que proporcionó un análisis dentro del nuevo paradigma de investigación (cuantitativa y cualitativa) en la Enseñanza de la Ciencia y Matemáticas. Los resultados mostraron que los estudiantes de licenciatura en química tienen creencias positivistas y que suelen son considerados por algunos como ingenuas, como la creencia en el modelo de decisión tecnocrática, la linealidad del desarrollo científico y tecnológico que lleva a el bienestar social y neutralidad de los conocimientos científicotecnológico. Basándose en estos datos y la literatura sobre el tema se elaboraron tres módulos de aprendizaje: a) Cuestionando la hegemonía del conocimiento técnico y científico, b) Las relaciones entre ciencia, tecnología, sociedad y medio ambiente - las relaciones CTSA c) Propuesta de temática para la enseñanza de la química en una perspectiva de CTSA: El Río Mossoró. Por último, el material producido se utilizó en dos cursos ocurridos en el Campus Central en el Centro de Educación Superior en São Miguel, ambos de UERN. Los participantes expresaron su aprobación al enfoque trajo de el experimento propuesto y de el caso de simulación contenidos en la propuesta de

Ensinando sobre a natureza da ciência: uma abordagem explícita e contextualizada a partir da história do vácuo

In last decades, the importance of including the contents of the Nature of Science (NOS) in Science Education has been emphasized. Several studies have focused on investigating the conceptions of NOS, supported by students and teachers, as well as design, implement and evaluate proposals that aim to provide a reflection on this theme in the educational context. Considering the complexity of such content, studies indicate the need for explicit and contextualized approaches and the History of Science (HS) is one of the possible paths to this inclusion. We started from the premise that, through a historical study, that aims to discuss the meaning and the basis of our "beliefs", we can know the process of building on what we "believe" and better understand its meaning. This thesis is part of this perspective, proposing to explore the History of the Vacuum, a themed high didactic potential still little used, in order to collaborate with the teaching content of NOS. We present actions on different fronts that originated three products in the context of this research. On the first front, we insert the research and production of instructional materials (three historical texts) to subsidize people interested in the implementation of HPS for educational context through this material. The relevance of this front is justified by the existence of gaps with regard to the production of such material for the context of teacher training. However, we consider that the preparation of instructional material of good quality and accessible does not guarantee that these resources will be used, if they will not be accompanied by discussions in teacher training, on how to use them, contexts and obstacles to be faced. The second part presented refers to the organization and implementation of a workshop for undergraduate students in physics and physics teachers, considering the instrumentalization of these individuals to the preparation and use of teaching strategies to approach aspects of NOS through episodes of History of the Vacuum, as well as the preparation of the text orientation for people interested in implementing the instructional material for secondary education. This guidance text contemplates the difficulties anticipated by the literature of the area and the main challenges faced by the participants about the didactic transposition of HPS for the educational context they were noted during the workshop. The relevance of this second front, in particular, is justified by the existence of gaps with regard to the inclusion of the theme of NOS and the HPS teacher training

Memórias da prisão: literatura e liberdade m estudo sobre Graciliano Ramos e Antonio Gramsci

La tese avvicina le Memorie dal carcere, di Graciliano Ramos e i Quaderni dal carcere di Antonio Gramsci, in una prospettiva in cui essi erano uniti per lo stesso ideale politico della prima metá del XX secolo e rappresentavano la resistenza intellettuale di fronte alla repressione. Entrambi furono vittime dell autoritarismo dei poteri fascisti e registrarono il periodo di prigione in differenti forme memorialistiche. Questi scrittori sono uniti anche per il contesto nazionale molto simile per la differenza economica tra le regioni. Condividono, inoltre, anche il concetto di arte e la certezza che l alienzazione dell intelligenza può essere superata solamente attraverso la ricostruzione delle basi nazionali per mezzo della conoscenza, dell educazione e della cultura. Si vuole mostrare come i concetti di Gramsci sono presenti non solo nella convinzione politica di Graciliano, ma in tutto il suo stile letterario memorialístico. Il lavoro, ancora, paragona le Memorie del carcere con due testi memorialistici di prigione in Italia, che sono Le mie prigioni, di Silvio Pellico, e Se questo è un uomo, di Primo Levi, per dimostrare che la proposta della letteratura gramsciana è molto più vicina allo scrittore brasiliano che ai due suoi conazionali.

Funcionalidade em pacientes após acidente vascular encefálico: relação com o sono e ritmo de atividade-repouso

It is known that sleep plays an important role in the process of motor learning. Recent studies have shown that the presence of sleep between training a motor task and retention test promotes a learning task so than the presence of only awake between training and testing. These findings also have been reported in stroke patients, however, there are few studies that investigate the results of this relationship on the functionality itself in this population. The objective of this study was to evaluate the relationship between functionality and sleep in patients in the chronic stage of stroke. A cross-sectional observational study was conducted. The sample was composed of 30 stroke individuals in chronic phase, between 6 and 60 months after injury and aged between 55 and 75 years. The volunteers were initially evaluated for clinical data of disease and personal history, severity of stroke, through the National Institute of Health Stroke Scale, and mental status, the Mini-Mental State Examination. Sleep assessment tools were Pittsburgh Sleep Quality Index, the Questionnaire of Horne and Ostberg, Epworth Sleepiness Scale, the Berlin questionnaire and actigraphy, which measures were: real time of sleep, waking after sleep onset, percentage of waking after sleep onset, sleep efficiency, sleep latency, sleep fragmentation index, mean activity score. Other actigraphy measures were intraday variability, stability interdiária, a 5-hour period with minimum level of activity (L5) and 10-hour period with maximum activity (M10), obtained to evaluate the activity-rest rhythm. The Functional Independence Measure (FIM) and the Berg Balance Scale (BBS) were the instruments used to evaluate the functional status of participants. The Spearman correlation coefficient and comparison tests (Student's t and Mann-Whitney) were used to analyze the relationship of sleep assessment tools and rest-activity rhythm to measures of functional assessment. The SPSS 16.0 was used for analysis, adopting a significance level of 5%. The main results observed were a negative correlation between sleepiness and balance and a negative correlation between the level of activity (M10) and sleep fragmentation. No measurement of sleep or rhythm was associated with functional independence measure. These findings suggest that there may be an association between sleepiness and xii balance in patients in the chronic stage of stroke, and that obtaining a higher level of activity may be associated with a better sleep pattern and rhythm more stable and less fragmented. Future studies should evaluate the cause-effect relationship between these parameters

Controle circadiano e homeostático do sono-virgília em pacientes com acidente vascular encefálico e correlações com a qualidade de vida e o nível de atividade física

The cerebral vascular accident is a neurological dysfunction of vascular origin that leds to development of motor sensibility, cognitive, perceptive and language deficits. Despite the fact that the main sleep disorders in stroke patients are well known, it is still necessary to analyze which mechanisms of regulation of sleep and wakefulness are affected. The objective of this study was to evaluate the changes in the circadian and homeostatic control of sleep-wakefulness in stroke patients and the correlations with quality of life and level of physical activity. The study analyzed 22 stroke patients (55± 12 years old) and 24 healthy subjects (57 ±11 years old). The instruments used in this study were questionnaires on sleep quality, daytime sleepiness, quality of life, physical activity level and the actigraphy. The data were analyzed using the Student `t test, Mann-Whitney test, ANOVA and Spearman's correlation tests. The results showed stability in the sleep-wake circadian expression with changes in the amplitude of the rhythm. However, significant changes were found related to the homeostatic component characterized by increased sleep duration, increased latency, fragmented sleep and lower sleep efficiency. Additional data showed decreased quality of sleep and increased daytime sleepiness, as well as decreased quality of life and level of physical activity. The results indicate that the interaction of circadian and homeostatic control of sleep-wake is compromised and the main reason might be because of the homeostatic component and the lower activity level resulting from the brain damage. Thus, further studies may be developed to evaluate whether behavioral interventions such as increased daytime activity and restriction of sleep during the day can influence the homeostatic process and its relation to circadian component, resulting in improved quality of nocturnal sleep in stroke patients

Análise do sono e da utilização de cartilhas educativas em pacientes com acidente vascular cerebral

O AVC é uma grande causa de mortalidade e uma das principais causas de incapacidade entre adultos. O presente estudo visa analisar o estado do sono e da utilização de cartilhas educativas em pacientes com AVC. No primeiro estudo foram abordados os fatores associados com os horários de dormir/acordar e no segundo estudo foi analisado o conhecimento e prática quanto às orientações sobre os hábitos de sono e estimulação cognitiva. No estudo 1 foram avaliados 50 pacientes sendo 28 homens, de faixa etária entre 25 e 90 anos que durante uma semana completaram um diário do sono e o registro de atividades através do Social Rhythm Metric (SRM) e do Indice de Nível de Atividades (ALI) e aplicação do questionário de cronotipo (MEQ). Utilizado o teste de correlação de Spearman verificou-se correlação significativa entre os horários de dormir/acordar com cronotipo e entre os horários de dormir/acordar com SRM e o ALI. No segundo estudo foram abordados 40 pacientes com idade média 56,1 ± 11,9 anos, sendo 15 homens e 25 mulheres; como instrumentos foram utilizados National Institute Health Stroke Scale (NIHSS) e em seguida os pacientes observaram cartilhas educativas sobre hábitos de sono e estimulação cognitiva respondendo se conheciam e se praticavam as orientações apresentadas. A análise estatística realizada através do teste de Fisher obteve como resultado, que das 10 orientações apresentadas sobre os hábitos de sono, 6 foram citadas como conhecidas e apenas 4 foram praticadas. Das 6 orientações cognitivas, não houve diferença significativa entre os que conheciam e não conheciam, mas em 5 delas a maior frequência foi dos pacientes que não praticaram. Os resultados dos estudos indicam a importância de avaliar o cronotipo antes do planejamento de reabilitação, e a necessidade de se estimular o ritmo social a fim de contribuir para a melhoria dos padrões de sono de pacientes. Verificou-se também que em relação ao conhecimento e prática de orientações apresentadas muitos pacientes não conheceram ou não praticaram orientações importantes a respeito de hábitos de sono e de estimulação cognitiva, mesmo na fase crônica da patologia, sugerindo que mais políticas de educação em saúde devem ser implementadas com intuito de causar mudança nos hábitos de vida dos pacientes com AVC

Um ensaio sobre as concepções de professores de Matemática: possibilidades metodológicas e um exercício de pesquisa

Este artigo tem como tema principal as concepções dos professores de Matemática. Considerando o termo concepção a partir do pragmatismo de Peirce, elabora-se um conjunto de parâmetros metodológicos - chamado de método indireto - a ser aplicado no estudo das concepções de professores de Matemática. Trata-se, em síntese, de investigar as concepções dos professores interpelando-os não sobre suas crenças, mas sobre suas práticas. Fundamentando essa abordagem indireta e explicitando-a em sua natureza qualitativa, o artigo segue apresentando, como exemplo, um exercício desse método indireto: um estudo sobre os critérios que os professores utilizam quando escolhem livros-texto para sua sala de aula, abordando, conseqüentemente, quais concepções de Matemática e de seu ensino e aprendizagem tais critérios desvendam. Partindo de depoimentos de professores de Matemática, o estudo indica que os professores agem com certa independência quando escolhem os materiais utilizados em suas atividades docentes. Buscam, ao mesmo tempo, apoio em uma vasta gama de livros didáticos, desconsiderando as particularidades de cada obra e as abordagens e perspectivas defendidas por seus autores. Embora submetam-se ao livro didático - considerado uma referência legítima e segura -, os professores o subvertem, buscando adequá-lo ao que consideram correto. Dessa constatação, algumas das concepções dos professores podem ser realçadas: o aluno, via de regra, é avaliado e classificado pelas lacunas que apresenta em relação aos conteúdos. Dessa postura, segue a valorização da precedência lógica dos conteúdos, de sua apresentação linear, e a defesa de pré-requisitos que viabilizariam o ensino e, conseqüentemente, implicam a legitimidade de aulas predominantemente expositivas.

Efeito do exercício físico matinal realizado sob luz solar no ciclo vigília-sono de adolescentes

The sleep onset and offset delay at adolescence in relation to childhood. Besides biological causes, some external factors as academic obligations and socialization contributes, increasing the burden of school and socialization. However, morning school schedules reduce sleep duration. Besides light strong effect, studies in humans have indicated that exercise influence circadian synchronization. To evaluate the effect of the morning exercise under sunlight on sleep-wake cycle (SWC) of adolescents, 160 high school students (11th year) were exposed to the following conditions: lesson in usual classroom (Group C), lesson in swimming pool exposed to sunlight (Group E), half of them carrying through physical activity (EE) and the other resting (EL). Each experimental group met two stages: assessment of SWC 1 week before and 1 week during the intervention, which was held in Monday and Wednesday between 7:45 and 8:30 am. In the baseline, there were applied the questionnaires "Health and Sleep" and cronotype evaluation (H & O). In addition, students were evaluated before and during the intervention by "Sleep Diary", "Karolinska Sleepiness Scale" (KSS), Psychomotor Vigilance Test (PVT) and actimetry. During the intervention, there was a delay in wake-up time on the weekend and a trend to greater sleep duration on week for the three groups. At the weekend, only the groups EE and EL increased sleep duration. There was no difference in bedtime, irregularity of sleep schedules and nap variables. The sleepiness showed a circadian pattern characterized by higher alertness levels at 11:30 am and sleepiness levels at bedtime and wake-up time on week. On weekends there were higher levels of alertness in these times. In the days of intervention, there was an increase of sleepiness at 11:30 am for groups EL and EE, which may have been caused by a relaxing effect of contact with the water of the pool. In addition, the group EE showed higher alert levels at 14:30 pm on Monday and at 8:30 am in the Wednesday, possibly caused by exercise arousal effect. The reaction time assessed through the TPV did not vary between the stages. The sleep quality improved in the three groups in the second stage, making impossible the evaluation of intervention effect. However, the sleep quality increased on Monday and Tuesday only on the group EE. From the results, it is suggested that the intervention promoted effects on the sleepiness at some day hours. In other SWC variables there were no effects, possibly due to a large SWC irregularity on weekends. Thus, the evaluation of higher weekly frequency EF is necessary, since only two days were insufficient to promote greater effect on adolescents SWC

Qualidade subjetiva do sono e queixa de insônia em pacientes com Acidente Vascular Cerebral

Brain injury can be associated with changes in the sleep-wake cycle. However, studies about sleep disturbances and their relationship with quality of sleep are scarce. Besides, it remains to be known how stroke affects the mechanisms of sleep. The aim of this study was to investigate quality of sleep, complaints of sleep disturbances and associated factors in stroke patients from the Physical Therapy services in Natal -RN. This was a cross-sectional descriptive study involving 70 individuals (aged 45-65 years), 40 patients (57 ± 7 years), 11 ± 9 months after injury, and 30 healthy individua ls (52 ± 6 years), evaluated with the Pittsburgh Sleep Quality Index (PSQI) and Sleep Habits Questionnaire. The data were analyzed by Chi-square test, t Student test and logistic regression. Poor quality sleep was found in 57,5% of the patients (6,3 ± 3,5) and was significantly higher than in the control population (3,9 ± 2,2) (t Student test, p=0,002). The patients showed significantly higher value of PSQI than controls: sleep latency (p=0,019), length of sleep (p=0,039) and dysfunction during the day (p=0,001). Regarding complaints of sleep disturbances (dyssomnias and parasomnias) analyzed by Chi-square test, the complaint of insomnia was the most prevalent (patients: 37,5%; healthy subjects: 6,7%; p=0,007). Regression analysis showed that sl eep latency (p=0,036) and complaint of insomnia (p=0,036) were associated with quality sleep. In addition, female gender (p=0,036) and complaint of broken sleep (p=0,003) were considered risk factors for the presence of insomnia. Our results show that stroke affects the homeostatic process of sleep. Shorter sleep latency and the absence of insomnia are considered protective factors for good sleep quality and this should be taken into consideration in the diagnostic and therapeutic strategies
