Intervalos de referência do zinco sérico e sua relação com os indicadores dietéticos, funcionais e bioquímicos em crianças saudáveis

Objective: To determine the zinc status and reference intervals for serum zinc concentration considering dietary, functional, and biochemical indicators in healthy children in the Brazilian Northeast. Methods: The study included 131 healthy children, 72 girls and 59 boys, between 6-9 years old. Anthropometric assessment was made by BMI/age; dietary assessment by prospective 3-day food register, and evaluation of total proteins was performed. Zinc in serum samples were analyzed in triplicate in the same assay flame using atomic absorption spectrophotometry. Results: All subjects were eutrophic according to BMI/age classification. With respect to dietary assessment, only the intake of fiber and calcium were below the recommendations by age and gender. Biochemical parameters were all within the normal reference range. Reference intervals for basal serum zinc concentration 0.70-1.14 μg/mL in boys, 0.73-1.17 μg/mL in girls, and 0.72-1.15 μg/mL in total population. Conclusions: This study presents pediatric reference intervals for serum zinc concentration, which are useful to establish the zinc status in the population or in specific groups.

Crianças e investigação: aspectos teórico-metodológicos e cuidados éticos nas produções dos grupos de pesquisa da UFRN

The concepts of childhood are part of a cultural construction and vary throughout history politically, economically and socially. Nouns such as "childhood" and "child" did not exist as sense of unity in periods prior to modernity, reinforcing their historical character as concepts that have been socially constructed as profess the Historical Social Psychology, theoretical perspective which will support this research. The sociology of childhood distinguishes the terms and changes the approach toward the adult researcher approach with respect to children, aiming to give voice to the child. When it comes to defining the role of children in research, the researcher must take into consideration several relevant criteria such as age, gender, time, listening to the adults close to the children, the level of language and education and which children that will be heard in a group. It is from this discussion, considering the importance of children's participation in the research that are established the purpose of this work, namely, to analyze the theoretical and methodological aspects and ethical guidelines considered in the research process with children, by researchers at the UFRN, presenting as specific objectives: analyze and discuss, from research reports, the adopted ethical procedures and methods used in research with children. Set the goal, it was made a search of the UFRN Research Groups in SIGAA in order to select those which investigate children for participating in our survey. Among the centers of UFRN, we selected the Health Sciences Centre - CCSA, the Humanities Center, Letters and Arts - CCHLA, the Biosciences Center - CB and the Health Sciences Center - CCS, a total of 64 finalized reports to be analyzed. And here it is the observation that the foolish reports were not analyzed for ethical reasons as the guiding of this dissertation is the coordinator of the research group mentioned. In this study, we chose the documentary analysis of the finalized reports from UFRN research projects teachers / researchers as procedure to set up the corpus of the research. Data analysis was performed from the qualitative analysis in the following categories were established: the concept of childhood, concept of child, age of the subjects, the research context, theoretical and methodological care adopted and ethical care. It is hoped that this study will contribute with reflections on the ethical and theoretical and methodological care on research with children. The research showed how some of the results: significant number of reports excluded by repetition, most reports did not bring any closing remarks, no different procedures for children, with rare exceptions, the ethical issue was not mentioned in 50% of reports.

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.

Métodos de avaliação nutricional para a suplementação oral com zinco em crianças pré-púberes não deficientes em zinco

Background: Zinc is an essential nutrient that is required for numerous metabolic functions, and zinc deficiency results in growth retardation, cellmediated immune dysfunction, and cognitive impairment. Objective: This study evaluated nutritional assessment methods for zinc supplementation in prepubertal nonzinc- deficient children. Design: We performed a randomised, controlled, triple-blind study. The children were divided into a control group (10% sorbitol, n = 31) and an experimental group (10 mg Zn/day, n = 31) for 3 months. Anthropometric and dietary assessments as well as bioelectrical measurements were performed in all children. Results: Our study showed (1) an increased body mass index for age and an increased phase angle in the experimental group; (2) a positive correlation between nutritional assessment parameters in both groups; (3) increased soft tissue, and mainly fat-free mass, in the body composition of the experimental group, as determined using bioelectrical impedance vector analysis; (4) increased consumption of all nutrients, including zinc, in the experimental group; and (5) an increased serum zinc concentration in both groups (p < 0.0001). Conclusions: Given that a reference for body composition analysis does not exist for intervention studies, longitudinal studies are needed to investigate vector migration during zinc supplementation. These results reinforce the importance of employing multiple techniques to assess the nutritional status of populations.

Da educação infantil ao ensino fundamental: o que contam as crianças sobre essa travessia na cultura de escola

From inquiries concerning the child as an individual with rights, this work takes as its object of study the perception of 5-7 years old children on their journey from kindergarten to elementary school, in a school culture. The objective of the research is, therefore, to investigate what the children tell in narratives drawn into a conversation circle about their experiences of school life in kindergarten and the first grade of elementary school. The participants were 18 children from a public school in the city of Natal (RN). Five rounds of conversation were held in which the children told a little alien, who was unaware of the school culture, what they knew about school and what they did at it. The research is linked to the project "Children's Narratives. What the children tell about childhood schools?"(Passeggi et all, 2011) and adopts epistemological principles and research methods of (auto)biographical education, taking as a working hypothesis the child's ability to reflect on their experiences and understand from their point of view, what happens to them. Analyses were organized based on the concept of school culture (Barroso, 2012). In the narratives of children, the three dimensions of school culture: the functionalist (purpose and rules), structural (structure and pedagogical organization) and the interactional (relations with others, with the spaces and with knowledge) are considered intertwined in their school perceptions and signal experienced tensions in a process of "conversion" from child to student. Children seem to realize the uniqueness of each level of education. They recognize as a characteristic of early childhood education the recreational activities, and as injunctions of the first year of elementary school the "study", "learning to read and write" to "be smart" to "change." The schooling will thus, constitute, in their eyes, as a time and a place where the children's culture gives way to school culture, and in this journey they experience that the desire to play and the duty/want to study cross the three dimensions of school. At the end of the journey, the status of children as cultural beings with rights is confirmed, whose narratives about school and about their experiences of "conversion" in a student, reveal much about the power of reflection on themselves, the school and the society in which they live, legitimizing their place in educational research and in child care policies.

Intervenção mediacional e hábitos alimentares: um estudo de crianças com síndrome de Down

The inadequacy about eating habits have been established as a serious problem nowadays. It is a multifactorial and difficult to handle, given their different nuances and causes. A population particularly exposed to the bad eating habits arising harm are individuals with Down syndrome, both with regard to the aspects inherent to the individual's own condition, regarding eating misfits, making it the weight control a necessary measure for a proper development. Thus, this study aimed to develop and evaluate a proposal based nutrition education from the assumptions of mediated learning, with children three to four years with Down syndrome. The participants were five children, four girls and a boy. Also included his parents and / or guardians. The data collection procedure involved the use of eight playful workshops with children and nutritional evaluation of those five meetings with parents and three home visits with each participating family. We tried to build with these children and their families a nutritional education to contribute to their daily choices of eating. Using listening, observation and questionnaire, besides playful interventions, it was observed that the first meaning of the act of eating is built in the family and reinforced by their social life. Overall, our sample characteristics seem to agree with the literature. During the intervention, the children showed attention, but little understanding of the content. With mothers, the results were different, with reflections on the inadequate power both the type of food offered, and quantity and so this offer is performed, conducted along the interventions changes in your lifestyle, such as perception of influence they had on their children in the formation of their eating habits, as well as less frequent intake of soft drinks and sweets. Nutritional interventions and mediations conducted with the mothers is that they seem to be effective strategies to combat obesity. Face of what was discussed, we see the importance of implementing intervention measures in combating and preventing overweight or obese since childhood, particularly with children with Down syndrome. One should prevent childhood obesity with educational and informative measures from birth, with family and with each child, through the primary health care and schools.

“É acompanhante ou usuária?” Implicações sobre a posição da família no atendimento a crianças e adolescentes em um Centro de Atenção Psicossocial da Infância e Adolescência - CAPSi

This study emerged and founded itself with the aim to analyze the position taken by the family – and the implications in this subjective area – in attending children and adolescents in a Childhood Psychosocial Care Center (CAPSi). A secondary goal has come up as the comprehension surrounding the institutional representation made about the family and the service offered to children, adolescents and relatives. For such, the historical perspective on the relation between the State (laws and institutions) and the family was resumed, and the understanding of how it was reconciled by the medical knowledge and attended the ideological and political means. The social and ideological transformations of the 20th century culminated in the need of change required by the Psychiatric Reform and the achievement of patients on the right to return home and to their families. This new situation, permeated by the attempt of building an assistance model in Mental Health, presented a peculiarity–the close relationship between family and Mental Health services. The observations and conversations at CAPSi that were the investigation objects in this research, intended to learn on the quotidian of families and the possible treatment alternatives that would take into account the family circumstances. Conceiving the status of the families in Mental Health services is a germinal matter yet to be adjusted among the active knowledge in the post-Reform devices. The discussion about the family bonds, anchored in the theoretical perspective of Binding Psychoanalysis brought up elementary concepts such as psychic heritage, denial pact, unconscious alliances, the familiar psychic set, among other. The concept of family organizer helped to think of the family trajectories and stablishes a sort of identity for the family, as well as interferes in the establishment of its boundaries. The family path within the institution, as well as the status they establish facing the institutional approach, reflect the ghosts and the organizers shared by the group-family. It follows that the family is an important protagonist to be considered in the current therapeutic and political processes and, thus, is key to welcome the family bonds for the alliances act over the affective destinations, as well as try to remain sealed from the proposed changes.

Associação entre comprometimento motor, mobilidade e qualidade de vida em crianças com paralisia cerebral espástica, nível I, II e III do Gross Motor Function Classification System

The objective of this study was to verify the association between some mobility items of the International Classification Functionality (ICF), with the evaluations Gross Motor Function Measure (GMFM-88), 1-minute walk test (1MWT) and if the motor impairment influences the quality of life in children with Cerebral Palsy (PC), by using the Paediatric Quality of Life Inventory (PedsQL 4.0 versions for children and parents). The study included 22 children with cerebral palsy spastic, classified in levels I, II, and III on the Gross Motor Function Classification System (GMFCS), with age group of 9.9 years old. Among those who have participated, seven of them were level I, eight of them were level II and seven of them were level III. All of the children and teenagers were rated by using check list ICF (mobility item), GMFM-88, 1-minute walk test and PedsQL 4.0 questionnaires for children and parents. It was observed a strong correlation between GMFM-88 with check list ICF (mobility item), but moderate correlation between GMFM-88 and 1-minute walk test (1MWT). It was also moderate the correlation between the walking test and the check list ICF (mobility item). The correlation between PedsQl 4.0 questionnaires for children and parents was weak, as well as the correlation of both with GMFM, ICF (mobility item) and the walking test. The lack of interrelation between physical function tests and quality of life, indicates that, regardless of the severity of the motor impairment and the difficulty with mobility, children and teenagers suffering of PC spastic, functional level I, II and III GMFCS and their parents have a varied opinion regarding the perception of well being and life satisfaction.

Intervenção mediacional na aprendizagem do braille: um estudo com crianças deficientes visuais

This study aimed to construct and evaluate a proposed mediational intervention with preschool children through reading workshops and writing in Braille system. The proposal is based on the concepts of Vygotsky on defectology and approach to the Mediated Learning Experience (MLE) developed by Feuerstein. For the research were drawn up ten Mediational workshops, in which they developed a work by reading a children's story and from her reading activities and writing in Braille system. The workshops took place within in kindergarten room of the institution. Study participants were four blind children, six and seven years in an institution that assists visually impaired people in the city of Uberaba / MG, and their mothers and the teacher responsible for the room in which they study. During the workshops, the children showed interest in participating in the activities of reading and writing in Braille. We believe that the data built during the research are not sufficient to establish a generalization, due to the small number of participants. However, at the end of the workshops and the assessment of participants' responses can infer the relevance of the proposal, because in addition to the interest shown and the request of the children there were more activities like that, it was noticed greater fluency in reading and greater ease in writing.

A entrada antecipada de crianças com menos d e 6 anos no ensino fundamental: Implicações para a constituição da infância

A alteração na definição da idade de ingresso no ensino fundamental de 7 para 6 anos pela Lei nº 11.114 de 2006 no Brasil tem suscitado debates nos campos da educação e do sistema de justiça sobre a data limite de ingresso. Este artigo tem como objetivo apresentar o cenário da implantação do corte etário para o ingresso no ensino fundamental, bem como problematizar a entrada precoce da criança nesta etapa da educação básica, buscando analisar as implicaçõesdo ingresso das crianças pequenas no ensino fundamental na limitação do seu direito educacional e para a constituição da infância. O acesso a cada uma das etapas da educação básica pressupõe uma faixa etária adequada e seu ingresso deve ocorrer tendo com referência a idade estabelecida e não laudos psicológicos e/ou pedagógicos que atestem a capacidade de cada criança, o que revela certa concepção de criança, infância e processos educativos.

Abolição da escravatura no Brasil sob o prisma da imprensa: fontes para o ensino e a pesquisa da história (1871-1885-1888)

O presente trabalho tem como objetivo dar continuidade à pesquisa desenvolvida em minha especialização em História do Rio Grande do Sul, momento em que investiguei sobre as formas de divulgação das leis abolicionistas, Ventre Livre, Sexagenários e Lei Áurea através da imprensa rio-grandina do século XIX representada pelos periódicos Echo do Sul, Artista, Comercial e Diário do Rio Grande. Dando continuidade à investigação, e partindo do pressuposto de que o jornal pode ser utilizado em sala de aula como fonte de pesquisa histórica, busquei verificar como esta fonte pode ser trabalhada com alunos do ensino fundamental de forma a desenvolver sua consciência histórica. A pesquisa foi pautada em investigações na área da Educação Histórica e na teoria da Consciência Histórica de Jörn Rüsen que investiga a caracterização e os fundamentos do conhecimento histórico e sua relação com a vida prática, buscando compreender como crianças e jovens aprendem história. Usei a metodologia de pesquisa-ação privilegiando o trabalho com a interpretação da linguagem dos textos históricos e a construção de narrativas por parte dos aprendizes de uma turma do 8º ano e uma turma de 8ª série do ensino fundamental de uma escola municipal da cidade do Rio Grande, nos dois últimos meses de 2013. Constatei que é possível a construção do aprendizado de História a partir da análise de matérias jornalísticas, comparando fontes e buscando a compreensão das possibilidades do discurso dos jornais, bem como este trabalho pode ser realizado através das tecnologias digitais de forma a torná-lo prazeroso para o estudante. Algumas considerações podem ser apontadas, entre elas a necessidade do professor de história oportunizar condições de aprendizagem que propiciem ao aluno sentir-se agente na construção do conhecimento e de um ensino de história significativo, dando-lhe condições de compreender de forma mais profunda a vida humana, bem como a necessidade da utilização, por parte dos professores, da narrativa como forma de ensino-aprendizagem. Seria a utilidade prática da história.

Mapeamento projetivo, associação de palavras e escala hedônica como instrumentos de avaliação da percepção de produtos de pescado por crianças da rede pública de ensino

Brazil is a country that is characterized by its low consumption of fish. With consumption records of 10.6 kg/ inhabitant/ year, it is lower than the recommended by the UN, that is 12 kg/ inhabitant/ year. The regular consumption of fish provides health gain for people and their introduction into the school feeding is an important strategy for the insertion of this food consumption habits in a population. In this context, the objective of this study was to understand the perception of fish with children from the public school system through the technical Projective Mapping (MP) and Association of Words (AP); and evaluate the acceptability of fish derivative in school meals. In the first instance with the intention to better understand the perception of children from different ages about the fish-based products, Projective Mapping techniques were applied through the use of food figures and word association. A total of 149 children from three public schools from Pato Branco, Paraná State, Brazil, took part in this study. Three groups of children aged 5-6, 7-8 and 9-10 years old were interviewed individually by six monitors experienced in applied sensory methods. Ten figures with healthy foods drawings (sushi, salad, fruit, fish, chicken), and less healthy foods (pizza, pudding, cake, hamburger, fries) were distributed to the children, who were asked to paste the figures in A3 sheet, so that the products they considered similar stayed near each other, and the ones considered very different stayed apart. After this, the children described the images and the image groups (Ultra Flash Profile). The results revealed that the MP technique was easily operated and understood by all the children and the use of images made its implementation easier. The results analysis also revealed different perceptions came from children from different ages and hedonic perceptions regarding the fish-based products had a greater weight in the percentage from older children. AP technique proved to be an important tool to understand the perception of fish by children, and strengthened the results previously obtained by the MP. In a second step it was evaluated the acceptance of fish burger (tilapia) in school meals. For this task, the school cooks were trained to prepare the hamburgers. For the evaluation of acceptance, the hedonic scale was used with 5 facial ratings (1 = disliked very much to 5 = liked a lot). Students from both genders, between 5 to 10 years old (n = 142) proved the burgers at lunchtime, representing the protein portion of the meal. The tilapia derivative products shown to be foods with important nutritional value and low calorie value. For the application of the multinomial logistic regression analysis there was no significant effect from the age and gender variation in the acceptance by children. However, statistical significance was determined in the interaction between these two variables. With 87 % acceptance rate there was potential for consumption of fish burgers in school meals.
