Implicações das síndromes da tensão pré-menstrual e do transtorno disfórico pré-menstrual na qualidade de vida

Enquadramento: Embora o ciclo menstrual seja um fenômeno normal na vida de mulheres em idade fértil, a ele podem se associar síndromes de intensidade variável. Objectivo: Determinar o impacto da síndrome pré-menstrual e da síndrome disfórica pré-menstrual na qualidade de vida de mulheres em idade fértil, comparadas a mulheres sem essas síndromes. Material e Métodos: Procedeu-se a estudo quantitativo, descritivo, correlacional, transversal, com 60 participantes do sexo feminino (16 com síndrome pré-menstrual, 28 com sintomatologia compatível com SDPM e 16 não apresentavam sintomas compatíveis com diagnóstico), A colheita de dados foi no Ambulatório de Ginecologia do Hospital Militar de nível terciário no período de janeiro a fevereiro de 2015, apresentando idade entre 18 e 56 anos, menarca há mais de um ano; ciclos menstruais em ausência de uso de terapia de reposição hormonal, com queixas associadas ao período menstrual. Três instrumentos de recolha de dados foram empregados: um questionário de identificação da paciente e caracterização de vida reprodutiva; o Questionário de Triagem de Sintomas Pré-menstruais e o Short Form Health-Survey com 36 itens. Para organização e análise dos dados, foi empregado o programa Statistical Package for Social Sciences, na versão 21.0. As variáveis foram dicotomizadas, para análise de contingência com o teste exato de Fisher. Para comparação de médias, foram utilizados o teste de diferença de médias de amostras independentes e o teste Kruskal Wallis, todos em nível de significância de 0,05. Resultados: A prevalência de síndrome menstrual igualou-se a 76,3%, sendo 46,6% compatível com síndrome disfórica e 29,7% com síndrome pré-menstrual. Esses grupos diferiram significantemente nos sintomas de ansiedade/tensão, fadiga/perda de energia, dificuldade de concentração, fome excessiva ou anorexia e sentimento de opressão. A síndrome disfórica pré-menstrual associou-se a maior comprometimento de relações sociais, familiares e domésticas, bem como à perda de saúde geral e de saúde mental, nos domínios de vitalidade, funções sociais, limitações devidas a problemas emocionais e saúde mental. Essas alterações não interferiram na percepção da libido e de orgasmo, mas alguns domínios da qualidade de vida estiveram associados a características reprodutivas. Conclusão: As síndromes pré-menstruais comprometem a qualidade de vida das utentes e requerem assistência voltada à melhoria do conhecimento das mulheres sobre seu problema de saúde. Palavras-chave: Síndrome pré-menstrual, Síndrome disfórica pré-menstrual, Qualidade de vida.

ADOLESCÊNCIA E TRANSTORNO DE CONDUTA: ESTUDO DO FUNCIONAMENTO PSÍQUICO E DA PERCEPÇÃO DA FIGURA PATERNA DE ADOLESCENTES INFRATORES

O presente estudo teve por objetivos: a) investigar conteúdos da psicodinâmica dos adolescentes infratores; b) descrever a percepção das interações afetivo-relacionais dos adolescentes em relação à figura paterna. Para isso foram estudados seis casos de adolescentes que cometeram infração e que cumprem medidas sócioeducativas, sendo cinco deles com 17 anos e um com 14 anos. Esses adolescentes freqüentavam o CEDECA (Centro de Defesa dos Direitos da Criança e do Adolescente) da cidade de Mauá (São Paulo), local onde os dados foram coletados. Foram utilizados como instrumentos o Procedimento de Desenho-Estória com Tema e entrevista semi-estruturada. A aplicação do procedimento foi feita com base nas seguintes instruções: desenhe um adolescente de Mauá e desenhe o pai de um adolescente de Mauá e, após cada desenho, foi pedido que o adolescente contasse uma história sobre o mesmo. De um modo geral, os resultados mostraram que o primitivismo e esteve presente na produção dos seis adolescentes, visto a presença de mecanismos de defesa como idealização, negação, cisão e outros mecanismos de defesa esquizóides. Também ficou evidente que a dificuldade de crescimento e evolução da personalidade, assim como a conduta anti-social estão associadas à qualidade da introjeção da figura paterna e a relação que estes adolescentes estabelecem com ela. Concluiu-se que o modo como se dá o desenvolvimento psíquico é fator determinante para que indivíduo seja levado á conduta delituosa. Por isso, são necessários mais estudos sobre a personalidade de adolescentes em conflito com a lei, para que o conhecimento científico possa contribuir em ações no âmbito familiar, bem como em programas de prevenção primária e secundária que possam dar condições de um bom desenvolvimento psíquico às pessoas antes que cheguem à adolescência e à idade adulta.

CARACTERÍSTICAS PSICOSSOCIAIS E DE PERSONALIDADE DE ADOLESCENTES INFRATORES EM CUMPRIMENTO DE MEDIDA SOCIOEDUCATIVA

Para atingir os objetivos propostos, ou seja, levantar e descrever indicadores socioculturais de uma amostra de adolescentes em cumprimento de medida socioeducativa, e descrever características psicológicas e de personalidade dos adolescentes infratores, num estudo que pesquisou adolescentes em cumprimento de medida socioeducativa. O trabalho foi realizado em duas as etapas: na primeira, os 47 adolescentes participaram de uma entrevista semidirigida; na segunda, dez desses adolescentes foram selecionados e submetidos a um instrumento projetivo para investigação de aspectos da personalidade: o “desenho da Figura Humana” de Machower, adaptado por Van Kolck (1956; 1984). A discussão teórica dos resultados baseou-se numa abordagem psicanalítica pós-freudiana para a compreensão da adolescência tanto como fase do desenvolvimento humano como dos comportamentos antissociais. Os resultados do estudo corroboraram a teoria advinda da literatura psicológica que aborda padrões comuns no período da adolescência, fase em que ocorre um complexo de fatores individuais da maturidade biológica associados ao meio social/cultural e que, por sua vez, estabelecem relações com as instâncias psicológicas ou psíquicas do sujeito junto com as características específicas de cada indivíduo. Na busca da compreensão desses padrões comuns da amostra dos adolescentes infratores utilizados no presente estudo, foram levantados dados do perfil psicossocial, cultural e demográfico; dos aspectos psicossociais e aspectos psicodinâmicos e de características de personalidade. A título de conclusão, o estudo destacou a problemática do adolescente em conflito com a lei, associada às questões sociais, de saúde mental, além do desenvolvimento psíquico, sinalizando a necessidade de ações psicoprofiláticas voltadas para população infantil, jovem, agrupamentos familiares e para a comunidade que representa seu entorno.

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.

O comportamento pró-social de crianças com sintomatologia do transtorno da conduta

Pro-social behaviors are seen regularly throughout our daily lives, as we often witness people giving alms, helping a neighbor move, donating blood, or taking care of a friend's children, among others. From an evolutionary perspective, such behaviors occur because they have a high adaptive value to our species, precisely due to our high degree of dependence on group living for survival. Probably, for this same reason, since children have shown a preference for prosocial behaviors over antisocial behaviors, this preference becomes more visible as we grow. However, children with symptoms of conduct disorder show a pattern of aggressive, impulsive and more selfish behaviors than children without such symptoms. Furthermore, these children also experience environments in which antisocial behaviors are more frequent and intense compared to the general population. Priming experiments are one way of measuring the influence of simple environmental cues on our behavior. For example, driving faster when listening to music, religious people help more on religious elements, like the bible, and children are more cooperative after playing games of an educational nature. Thus, the objectives of the current study were to: evaluate whether there is any difference in generosity, through sharing behavior, among children with and without symptoms of conduct disorder; analyze the influence of prosocial priming on sharing behavior on children with and without symptoms of conduct disorder; and finally, analyze from an evolutionary perspective, the reasons given by children with and without symptoms of conduct disorder for sharing or not sharing with their best friend in a classroom environment. To address this question, the teachers of these children were asked to respond to an inventory that was designed to signal the presence or absence of symptoms of conduct disorder. Children identified as having or not having symptoms of conduct disorder could then undergo an experimental (with priming) or control (no priming) condition. Under the experimental condition, the children were asked to watch two short videos showing scenes of helping and sharing among peers, to perform a distraction activity, and finally to chose two of four different materials presented by the researcher and decide how much of these two materials they would like to share with their best friend in the classroom. Then the children were asked about their reasons for sharing or not sharing. Children subjected to the control condition performed the same activities as in the xi experimental condition, but did not watch the video first. The results showed a notable difference in the effect of priming in accordance with the child's stage of development; a difference in the amount of material donated to a best friend by children with and without symptoms of conduct disorder, and a change in this observed difference with the influence of pro-social priming; and finally, a convergence in the thinking of children regarding their reasons for sharing with evolutionary theory. The results of this study also indicate the importance of individual factors, developmental stage, environmental and evolutionary conditions in the pro-social behavior of children with and without symptoms of conduct disorder.

Padronização de testes para avaliação do estado de mania e potencial anti-maníaco de um agonista do receptor NOP

Bipolar disorder is characterized by mood impairment, alternating between mania/hypomania and depression, and its exact pathophysiology is already unknown. The treatment of bipolar disorder is based on prevention of the manic and depressive episodes using mood stabilizers. Nociceptin/orfanin FQ (N/OFQ) is an endogenous heptadecapeptide which binds as an agonist to NOP receptor, which is a G-coupled inhibitory receptor. N/OFQ and its receptor modulate a lot of functions in the organism, including emotional processes. It is known that the plasmatic concentration of N/OFQ is altered in patients in both phases depressive and manic of bipolar disorder and it is assumed that this system has a role on the etiology of this disorder. Concerning mania, the animal models used in research tend to focus in an unique aspect of the manic behavior, as hyperactivity or agressivity. In the 60’s, the hole board test was proposed, and it consists of an apparatus with holes where a behavior known as head-dippings is measured. High levels of head-dippings are suggestive of neophilia, while low levels can be characteristic of an anxious-like behavior. As the increase of exploratory and goal-directed behavior are characteristics of manic behavior, this test could help in mania research. Thus, this work was organized in 3 steps and aims to: (1) investigate the induction of a manic-like state promoted by ouabain, a Na+/K+-ATPase inhibitor, in the mouse open field test; (2) set up the hole board as a test to measure manic-like behaviors; and (3) investigate the N/OFQ effects in prevention of this kind of behavior on hole board. Male Swiss mice were used in this study, and they take part of only one of the described steps. Depending on the step performed, mice received one or more of the following treatments: (1) ouabain 10-6 , 10-5 , 10-4 , 10-3 or 10-2 M, intracerebroventricular (icv); (2) sodium valproate 300 mg/kg, intraperitoneal (ip); (3) sodium valproate 400 mg/kg, ip; (4) diazepam 1 mg/kg, ip; (5) methylphenidate 10 mg/kg, ip; and (6) N/OFQ 0,1 or 1 nmol, icv. The results suggest that hole board can be used to evaluate a manic state, through analysis of different animal behaviors. However, it was not possible to standard the model of Na+ /K+ -ATPase dysfunction through ouabain administration in mice. Moreover, the data suggest that N/OFQ, at the doses tested, has not affected the methylphenidate-induced mania-like behavior. Taken together, the results point to a new approach of manic research, through the hole board using. However, more studies are necessary in order to verify the role of N/OFQ system on bipolar disorder.

A criança com transtorno do espectro autista (TEA) e o professor: uma proposta de intervenção baseada na experiência de aprendizagem mediada (EAM)

The presence of students with Autism Spectrum Disorder (ASD) in regular schools has increased and with it, the need to develop interventional strategies that enhance their learning. One of the tools that can facilitate this process is Mediated Learning, defined as an interaction style where the teacher selects, modifies, enhances, and interprets environmental stimuli in order to promote student learning. In recent years several studies have used the Mediated Learning Experience Scale (MLE; Lidz, 1991) as a tool to assess the mediator behavior. These studies have suggested that the EAM Scale can provide important guidelines for planning educational interventions, particularly those involving students with special needs. In order to extend these findings, this study aimed to evaluate the effects of an intervention based on the Mediated Learning Experience on social / academic skills of a child with ASD, enrolled in the 4th grade of a regular elementary school. This collaborative study was held in the city of Parnamirim, state of Rio Grande do Norte, in 2014. A 9-year old boy with ASD and his teacher participated in the study. The research used a quasi-experimental A-B design (baseline and treatment) to evaluate the teacher's behavior. Qualitative procedures were also used to analyze the dyad´s responses. Teacher and student behaviors were observed in three school routines during baseline. Based on the results of this phase, a training program was designed for the teacher. Dyad behavior was analyzed again after training in the same routines. The results of this phase showed qualitative and quantitative changes in levels of teacher mediation. Additionally, data indicated that the child enhanced his social and academic skills during the intervention.

A relação entre memória de trabalho e competência leitora em crianças em risco de transtorno de aprendizagem do Projeto Acerta: um estudo exploratório

Reading and writing are essential rights, which involve individual and social aspects; in addition, these skills are important when it comes to socio economic and political development, critical thinking and an active participation in society (UNESCO 2005). From a neurobiological standpoint, our brain is not prepared for reading, and this practice must be deliberately acquired via instructional guidance (DEHAENE 2009). However, reading disorders and deficits within executive functions, such as low working memory capacity, can make reading arduous. The aim of this study is to investigate the development of reading skills within 45 third grade students from public schools in the city of Natal – RN and its connection to working memory capacity, through information gathered from the Provinha Brasil, data generated from working memory tasks (Portuguese version of AWMA - Automated Working Memory Assessment) and fluid intelligence measures RAVEN. Based on this main objective, we attempted to answer the following research questions: (a) What are the correlations between working memory and reading scores?; (b) What characterizes the relationship between working memory capacity and the risk of reading disabilities amongst the participants in this study?; Following a quantitative research methodology, the Provinhas Brasil from 3rd grade students belonging to the six public schools members of Project ACERTA - Avaliação de Crianças em Risco de Transtornos de Aprendizagem (CAPES/OBEDUC)- were analyzed and compared to the scores from the working memory tests and the fluid intelligence ones. Results indicate that reading skills within children at risk of reading disabilities are directly linked to working memory capacity, especially with regards to the phonological component. It is also evident that the participants with less working memory capacity show more difficulties in the reading abilities that demand interpretation skills. Thus, we intend to contribute to the discussion regarding the diagnosis of reading disabilities and possible intervention strategies.

Etiologia da doença periodontal

A doença periodontal é caracterizada como um conjunto de condições inflamatórias, de carater crônico ou agudo, e de origem bacteriana, que começa por afetar o tecido gengival e pode levar, com o tempo, à perda dos tecidos de suporte dos dentes. As reações inflamatórias e imunológicas à placa bacteriana representam as características predominantes da gengivite e da periodontite. A reação inflamatória é visível, microscópica e clinicamente, no periodonto afetado e representa a reação do hospedeiro à microbiota da placa e seus produtos. O processo de infecção no sulco periodontal leva, inicialmente, a formação de uma mucosite periodontal, que pode ser definida como uma inflamação dos tecidos moles periodontáis, sem ocasionar perda óssea, sendo reversível, se o seu diagnóstico for atempado. Os processos inflamatórios e imunológicos atuam nos tecidos gengivais para proteger contra o agressãoes microbianas, impedindo os microrganismos de se disseminarem ou invadirem os tecidos. Em alguns casos, essas reações de defesa do hospedeiro podem ser prejudiciais porque também são passíveis de danificar as células e estruturas vizinhas do tecido conjuntivo. Além disso, as reações inflamatórias e imunológicas cuja extensão alcança níveis mais profundos do tecido conjuntivo, além da base do sulco, podem envolver o osso alveolar nesse processo destrutivo. Assim, tais processos defensivos podem, paradoxalmente, ser os responsáveis pela maior parte da lesão tecidual observada na gengivite e na periodontite. O objectivo desse trabalho é fazer uma revisão de literatura específica sobre a etiologia da doença periodontal respectivamente. Serão descritos os principais agentes microbianos que estão relacionados com a doença periodontal e a forma como influenciam o desenvolvimento da doença, procurando desta forma contribuir para a procura de tratamentos mais eficientes.
