Estudo epidemiológico e monitoramento de Lamivudina (3TC) e Zidovudina (AZT) na terapêutica do HIV-1 em pacientes de Belém – PA e suas correlações com as funções hepática, renal e nutricional, Belém, Pará

A estimativa de pessoas infectadas pelo HIV no mundo, no ano de 2006, foi cerca de 39,5 milhões. No Brasil, o Ministério da Saúde indica terapia para pacientes com manifestações clínicas associadas ao HIV-1 e para aqueles com contagem de linfócitos T CD4⁺ abaixo de 200 células/ mm³. Paralelamente aos benefícios da terapia anti-retroviral há o reconhecimento de efeitos adversos, como miopatia, lipodistrofia, pancreatite, hepatotoxicidade e acidose lática. A complexidade dos esquemas terapêuticos torna a adesão à terapia difícil, contribuindo para a falha terapêutica. Neste trabalho foi realizado um estudo epidemiológico, de monitoramento de Lamivudina (3TC) e Zidovudina (AZT) e correlacionado com as funções hepática, renal e nutricional em pacientes portadores de HIV-1, atendidos na CASA DIA, em Belém/PA. O grupo populacional estudado constou de 60 portadores do HIV-1 de ambos os gêneros, com faixa etária de 20 a 61 anos, que faziam uso de AZT e/ou 3TC. Os níveis plasmáticos de aminotransferases, uréia e creatinina foram determinados por fotometria de absorção e, por Cromatografia Líquida de Alta Eficiência, foram determinadas as concentrações plasmáticas de 3TC e AZT. O estado nutricional foi avaliado através do Índice de Massa Corpórea (IMC). As concentrações de 3TC variaram de 1,283 a 355,953 μg/mL, enquanto que as de AZT variaram de 0,008 a 22,544 μg/mL. A concentração de 3TC evidenciou associação com a ocupação (p < 0,05) e com a creatininemia (p < 0,0001), mas não com as aminotrasnferases e uremia (p > 0,05). Não encontramos associação entre a concentração de AZT com as informações demográficas e com a creatininemia (p > 0,05), todavia verificou-se associação com as aminotransferases e uremia (p < 0,0001). O IMC revelou associação com todos os parâmetros estudados: concentrações de 3TC, AZT, aminotransferases, uremia e creatininemia (p < 0,05). Concluímos que as concentrações de 3TC podem afetar os níveis de creatinina e sofrem influência do estado nutricional do paciente, enquanto que as concentrações de AZT podem alterar os níveis de aminotransferases, uréia e também são influenciadas pelo estado nutricional, ratificando os processos farmacocinéticos desses fármacos.

Avaliação visual de sujeitos expostos de forma ocupacional a solventes orgânicos através de métodos psicofísicos

Os solventes orgânicos são substâncias neurotóxicas que podem causar efeitos danosos sobre as funções visuais. É comum a exposição ocupacional a esses tipos de substâncias, pois elas apresentam grande aplicabilidade em inúmeras atividades. Os efeitos podem ser quantificados por testes psicofísicos. Os testes mais usados nesse tipo de avaliação são de ordenamento de matizes, como o Teste D15 Dessaturado de Lanthony e o Teste dos 100 Matizes de Farnsworth-Munsell, e avaliação de sensibilidade ao contraste espacial de luminância, como MCT 8000 Vistech, VCTS 6500 Vistech e FACT 101. Em geral esses testes descrevem perda de discriminação de cores, afetando tanto o eixo azul-amarelo quanto o eixo verde-vermelho, e diminuição da sensibilidade ao contraste de luminância principalmente para as frequências espaciais mais baixas. Existe correlação positiva entre os resultados da avaliação psicofísica e vários marcadores biológicos e ambientais, mas essa correlação depende do marcador e do tipo de solvente ao qual os indivíduos são expostos. Fatores como alcoolismo crônico e tabagismo inveterado podem interferir no processo de correlacionar esses resultados.

Percepções dos alunos sobre sua própria (des) motivação: estudo comparativo em turmas dos cursos extensivo e intensivo de licenciatura em letras língua inglesa

Tanto a motivação quanto seu oposto – a desmotivação – têm sido estudadas no âmbito da aprendizagem de línguas estrangeiras. No entanto, poucos trabalhos investigam esses construtos do ponto de vista de sua dinamicidade. Esta pesquisa tem por objetivo compreender a motivação e a desmotivação em alunos de uma turma extensiva e uma turma intensiva de graduação em Letras Língua Inglesa e as implicações destas na aprendizagem da língua alvo. Utilizando os pressupostos teóricos estabelecidos por Dörnyei e Ushioda (2011), Dörnyei (2011, 2001), Ushioda (2008), Gardner (2007), Deci e Ryan (2000) entre outros, analisa-se os dados coletados por meio de um questionário e dos históricos escolares dos alunos de ambas as turmas. A pesquisa em questão é um estudo de caso que faz uso do método comparativo. Participam dela 21 alunos de duas turmas de licenciatura em Letras Língua Inglesa da Universidade Federal do Pará, Campus Universitário de Bragança: 11 alunos da turma extensiva e 10 da turma intensiva. Percebeu-se que, embora existam padrões motivacionais que agrupam os alunos, a motivação é individual e mutante, já que o processo motivacional não acontece da mesma forma e exerce influências diversas em sujeitos diferentes e muda no decorrer do tempo em um mesmo indivíduo. Os dados também mostram a complexidade do construto, pois o fato de haver motivação não significa que influências negativas não possam ocorrer, bem como influências negativas podem ser impulsos para um posterior aumento do nível motivacional. Além disso, constatou-se que a motivação percebida pelos alunos não garante bons resultados nas disciplinas cursadas. Esta pesquisa poderá ajudar na compreensão do processo motivacional como um sistema dinâmico e a entender que tanto os alunos de turmas extensivas quanto os de turmas intensivas podem ser motivados, já que a motivação é uma condição individual.

As dificuldades de implantação de atividades experimentais investigativas no ensino de Química

Dissatisfaction with certain aspects of the educational processes of the traditional teaching has always existed, and new teaching methods have been routinely studied. The experimental investigative activity is one of those alternative practices. In this type of activity the experimentation is inserted with an investigative approach, in which the student must build the concept, with proposals that represent solutions to the excited problems. In the teaching of chemistry, specifically, the need and importance of experimentation is evident, beyond motivate students, aid in the understanding of chemical concepts relating them to reality. Realizing the contributions of this methodology for teaching and learning, through this research was conducted to understand the difficulties encountered by teachers for planning and implementation of these activities in the teaching of chemistry and therefore the reasons for the dominance of traditional teaching method. The subjects were undergraduate students of chemistry course that developed and implemented differentiated learning activities for teaching and teachers who accompanied the high school students who participated in the university extension project Inclusion Science and University students and teachers from public: Teaching and Learning Chemistry focuses on research and practice”. Through the data it was possible to identify some factors that affect and hinder the implementation of experimental activities in general, not only the investigative. However, despite the difficulties experienced by undergraduates, the majority considered the activity as an alternative teaching method interesting and innovative, able to produce interest, motivation and participation of students with subsequent learning. As well as the teachers, what with all the difficulties that they had declared facing when applying experimental activities, they admitted the pedagogical...

Fazendo conexões com o mundo real: uso de conceitos e modelos da física no contexto da zoologia

There are considerations of that the education of Physics of the way as comes being driven us textbooks and consequently in classroom, is distant and distorted of their real purpose. We notice that the education of this science through the Physical school discipline, has I assume a character of preparation for university entrance exams exercises resolution, exceling for the memorization of formulae and by the mathematical solutions, fact that looks to cause to it is lacking of motivation and to the disinterest of the students regarding his contents. Since we are surrounded by phenomena, events, elements of the nature, new technologies, objects and so many others that can be explained and many times until applied and/or reproduced by means of physical concepts, there is no reason for treat to Physical as somewhat academic and remote of the reality. The little interest of high school students by the discipline of Physics and their poor performance in the learning of his contents has led to the search of new paths, resources and strategies that promote a more meaningful learning. Taking into account these facts, we seek in this course conclusion work, observe, analyze and apply concepts of the Physical one in multiple elements of ours routine, doing use of the interdisciplinary nature as a possible mechanism. The animals exert a fascination on most people. Much of what we see in their way of being and behaving can be explained by the laws of Physics and its models. Their physique, behavior and activities involve diverse movements, communication and sensing as physical limitations varied. Zoologists and physicists build models in an attempt to explain or understand animal behavior using well-established physical principles. The creation of physical models is going to approach a problem, identifies the fundamental information and removing all of the irrelevant details. An example...

Associação entre posicionamento do aluno na sala de aula e desempenho escolar

This research was aimed at analyzing whether there is an association between the positioning of the pupil in the classroom and his academic performance, as well as to diagnose the main factors underlying the association. Thus, this study analyzed 4 Elementary School II institutions of both public and private educational systems, in Botucatu, São Paulo, Brazil during a school year bimester. To register the positions students were seated, 29 similar classes (containing 6 rows x 6 columns) were investigated, each one with around 30 students, which resulted in a sampling of 859 students. For the questionnaire application, which objective was to verify the main reason for students’ seat choice, the same 29 classes were investigated. However, the sampling number was reduced to 692 students. In turn, for the collection of school performance and absence percentage of each student for the bimester in question, teachers’ evaluation books were used. As a result, it was found that the lower the percentage of the student's absences, the greater is their performance at school, and the greater their performance at school is, the closer up front to the board they are seated. Finally, the closer up to the board they are seated, the more their motivation and interest in learning increase. Therefore, there is an association between the position of a student in the classroom and his or her academic performance, where the association is conditioned by the motivation and interest in learning

Qualidade de vida do trabalhador de enfermagem de um hospital Estadual

The search for quality of life (QOL) is now an ideal among thousands of people worldwide and is currently the subject has been studied in different areas of knowledge. Thus, one can perceive it in different dimensions, each with its due importance to people's lives. The verification of quality indexes of work life (QWL) may provide information on factors that directly interfere with the satisfaction and personal motivation and collective, with reflections on the structure and excellent service. To this end, we carried out a study to know the characacteristics of quality of life of nursing professionals in a state hospital in São Paulo State, based on short range of quality of life of the World Health Organization (WHOQOL-BREF). This work is a study with a quantitative approach, cross-sectional descriptive and exploratory data analysis using descriptive statistics, involving a sample of 281 nurses who answered the scale for measuring quality of life, composed of four areas: physical, psychological, social relationships and environment. In the study, these areas were related to the professional position, and shift work. There was a satisfactory quality of life in the study population in different areas of WHOQOL-BREF. There was no statistically significant changes in quality of life among the variables. It follows that the population presented data consistent with an adequate quality of life, thus making relevant to addressing the quality of life of nursing in a healthcare organization which has as fundamental to the pursuit of quality through the accreditation process second hospital established by the National Accreditation Organization (ONA) that aims at establishing and implementing a process of improving health care, thereby stimulating the services to achieve higher standards of quality

Crenças sobre compreensão oral em língua estrangeira de alunos concluintes de um curso de Licenciatura em Letras

In this article we present and discuss a number of beliefs about listening comprehension among students who were in their last year of a teachers’ certification Letters course in Italian and Portuguese. The data were collected by means of questionnaires answered by all the participating students, logs and interviews conducted with five of the participating students, classroom observation, lessons recorded on audio and video, and diaries. The study is supported by a rationale on beliefs and on definitions of listening comprehension as a skill. The analysis indicate that a number of students showed lack of motivation and low expectations about developing oral comprehension skills due to several drawbacks in foreign language learning during their teacher education course. However, other beliefs that emerged from the data, such as the importance of visual aids to help understanding an oral text, seem to have a positive effect towards a satisfactory proficiency level in oral comprehension.
