A produção tardia da profissionalização docente e seu impacto na redefinição identitária do professorado do ensino fundamental

El objetivo de este estudio consistió en capturar y reconstituir el modo por el cual profesoras y profesores vinculados a la educación infantil y a la fase inicial de la enseñanza fundamental producen su identidad docente, en el contexto de una tardía profesionalización. El campo de esa pesquisa envolvió tres instituciones públicas de enseñanza superior, dos en Natal (RN) y una en João Pessoa (PB), que desenvulven programas especiales de formación de docentes vinculados a las respectivas redes locales de enseñanza. Para el atendimiento del objetivo arriba propuesto, fue utilizada la teoría de las representaciones sociales para la captura de los elementos constitutivos de las representaciones sociales del profesorado conforme la formulación de Serge Moscovici y colaboradores, considerándose, aqui, especialmente, la contribución de Abric en su complementar teoría de nucleo central de las representaciones. Teniendo en vista la necesidad de identificación de los elementos estructuradores de las representaciones, y definidores de las identidades en cuestión, se privilegió en la pesquisa la producción discursiva docente y sus condiciones de producción. La utilización de sus evocaciones, bien como de las fuentes escritas por los propios sujetos envolvidos, oportunizó el afloramiento de las diferentes faces constitutivas del ser profesor/a . El corpus decorriente de ese estudio fue entonces somentido a una serie de diferentes métodos / técnicas condensadas en programas informatizados y otros manuales en um esfuerzo para conferir un mayor rigor al análisis de los resultados apuntados. Se utilizó, aún, un referencial de análisis del discurso para viabilizar la emergencia de diferentes ângulos de la configuracion de la identidad en foco. Los resultados apuntam para un significativo deslocamiento de las representaciones docentes, bien como permitem afirmar la hipótesis, inicialmente puesta, de que la profesionalización docente ocurre no apenas de manera tardía, como también viene provocando una resignificación de los referentes de identidad de esos profesionales

Gravidez tardia: bem-estar subjetivo e percepção da gestação

The subjective well- being (SWB) is formed by global judgments of satisfaction with life, or with peculiar domains the positive and the negative emotional experiences. The perception in turn, is the process of interpretive process of sensory data with cognitive or informative sense, absorbed in function of a context. From this perspective, the research aimed to evaluate SWB and the perception of advanced age pregnant women. Participated in the survey 80 pregnant with 35 years old or older (Group A or older) and 80 pregnant aged between 20 and 34 years old (Group B or young adults). The instruments used were: the scale of subjective well-being and a questionnaire, that included sociodemographic informations, items about pregnancy and a statement based on the Free Association of Words Technique (FAWT) to approach the perception of pregnancy. The data from the questionnaire and scale, in order to compare the data between groups suffered descriptive and inferential statistical analyzes. The analyzes performed with chi-square test among groups, which had values that were statistically significant, with the sociodemographic variables the type of contraceptive and health problems. The indicators of the SWB had further more by means in groups. The results of the Wilcoxon's test that there were no differences between the groups referred above. In the relation indicators of well being with variables age, education and income, some associations were significant. In addition, the words derived from the (FAWT) were analyzed using the software Programmer s Permenttant l´Analyse des Evocation (EVOC2000) and categorized according to content analysis of Bardin in three thematic categories (positive and negative affects, perception of gestation and implications of pregnancy) discussed as a group, since most of words were common. The study highlights shown how similar were the presented data by pregnant women surveyed. It is supposed about this fact the similarity is related to the social context. The relevance of this study for the health care network is to help with proposals aimed at specific improvements to the public and the sector, beside demonstrate that advanced age pregnant women and young adulst in the researched context showed no differences in the most of the studied characteristics

Histórias de adoção tardia: considerações a partir da analítica existencial heideggeriana

Adoption establishes a filiation status, resulting from a legal act, which attributes to the child and parents the rights and obligations associated with such condition, being legally irrevocable. Nevertheless, in practice there are adoptions that do not concretize and the child returns to justice during or even after the legal process is closed. Late adoption is the denomination of the adoption of children over two years and it is still permeated by myths and stigmas, leading to a frequent return of the child to justice in these cases. The late adoption involves a process of building a unique relationship with a child whose backstory is commonly marked by the dissolution of the relationship with the family of origin, due to violation of rights and, in some cases, the experience of institutional care. Given such a scenario, this research, based on the Existential Analytic proposed by Martin Heidegger, seeks to understand the experience of mothers and children in the process of late adoption, in order to obtain subsidies to psychological attention in this context. This is a qualitative, phenomenological study with a comprehensive focus. The participants were two mothers and two children who have gone through late adoption for about two years. The procedures of data generation contemplated narrative interviews with mothers and individual meetings with children, in which ludic resources were used as mediators of expression (free drawings, unfinished children's story and "Story-Drawings" on late adoption). The procedures were audiotaped and transcribed. Data analysis was grounded in Heidegger's hermeneutics. The late adoption process, permeated by historical, social and cultural determinants and the web of meanings that create the historical singularity of each person involved have proved to be complex as seen in the narratives. The construction of the meanings of parenthood and filiation has been developing in the families in the study, from the experience of being-with-the-other, caring and dwelling in their peculiar modes of expression. The family of origin and the adoptive family mingle and differentiate by means of the experience of children, especially because of the existence of biological siblings. Data point to the importance of psychological care to family core in late adoption processes

Analysis of testosterone pulsatility in women with ovulatory menstrual cycles

Objetivo: Avaliar o padrão pulsátil da secreção da testosterona em mulheres normais. Métodos: Oito mulheres saudáveis com ciclos ovulatórios foram selecionadas. Amostras sanguíneas foram coletadas a cada dez minutos durante seis horas, começando entre 7 e 8 h da manhã, após dez horas de jejum, nas três fases do ciclo menstrual: folicular média (Dia 7), folicular tardia (Dia 12) e lútea (Dia 21). Foram mensurados: testosterona, LH e, no basal, também SHBG. Resultados: A frequência dos pulsos de testosterona, média da amplitude do pulso, porcentagem do incremento da amplitude, duração e intervalos dos pulsos foram similares nas três fases (p > 0,05). A pulsatilidade do LH foi estatisticamente diferente entre as três fases (p < 0,001), caracterizando padrão característico do ciclo ovulatório normal. Conclusões: Esses dados aumentam o conhecimento sobre o padrão de secreção da testosterona no ciclo menstrual humano e representam uma contribuição para a investigação clínica, tanto no hiperandrogenismo como na síndrome de insuficiência androgênica __________________________________________________ ABSTRACT Objective: To evaluate the pattern of the pulsatile secretion of testosterone in normal menstrual cycle. Methods: Eight healthy women with ovulatory menstrual cycles were enrolled. Blood samples were collected at ten-minute intervals for six hours, starting between 7 and 8 am, after a ten-hour fasting, in three phases: mid-follicular (Day 7), late follicular (Day 12) and mid-luteal phase (Day 21). Samples were assayed for testosterone, LH and the baseline also for SHBG. Results: Testosterone pulse frequency, mean amplitude pulse, percentage of increment in pulse amplitude, mean duration of pulses and pulse interval were similar in the three phases. LH pulsatility was statistically different among the three phases (p < 0.001) representing normal ovulatory cycles. Conclusions: These data increase the knowledge about the testosterone secretion profile in the human menstrual cycle and can be used as a contribution to clinical investigation in both hyperandrogenism and androgen insufficiency syndrome

Retinal nerve fiber layer analysis using GDx® in 49 patients with chronic phase DUSN

To describe retinal nerve fiber layer changes in late-stage diffuse unilateral subacute neuroretinitis eyes and compare these results with healthy eyes observed through nerve fiber analyzer (GDx®). Methods: This is a retrospective case-control study in which 49 eyes in late-stage diffuse unilateral subacute neuroretinitis were examined from May/97 to December/ 01. First, eyes with diffuse unilateral subacute neuroretinitis and healthy contralateral eyes (Control Group I) were statistically matched. Subsequently, eyes with diffuse unilateral subacute neuroretinitis were compared with eyes of healthy patients (Control Group II). Results: Eyes from Control Groups I and II had higher relative frequency of “within normal limits” status. Eyes from the diffuse unilateral subacute neuroretinitis (DUSN) Group had higher frequency of “outside normal limits” and “borderline” status. Control Groups I and II had absolute values different from the DUSN Group regarding all parameters (p<0.05), except for Symmetry in Control Groups I and II, Average thickness and Superior Integral in control group II. Conclusion: Patients with late-stage diffuse unilateral subacute neuroretinitis presented presumed decrease in nerve fiber layer thickness shown by GDx®. Retinal zones with larger vascular support and larger amount of nerve fibers presented higher decrease in the delay of the reflected light measured by the nerve fiber analyzer

Estudo de ß-glucanas extraídas dos fungos Geastrum saccatum e Polyporos dermoporus: características químicas e atividades biológicas

Fungal polysaccharides have received a great deal of attention due to itsbecause of their potential use in a wide rangegreat variety fromof industries. Some studies have demonstrated that polysaccharides extracted offrom basidiomycetes they have presented significant properties as anti-inflammatory, antimicrobial, antioxidant and anti-tumoral properties. In spite of thisDespite these potential properties, these mushrooms have not been insufficiently investigated, and the great number of antibiotics number produced forby these organisms suggests that they canmay be a new source of bioactives composites source. In tThe present work, reports onlated the chemical composition, potential antioxidant, antiinflammatory and citotoxycity of extracted polymers extracted offrom the fruits bodies of the fungiius Geastrum saccatum and Polyporus dermoporus, native mushrooms of the Atlantic forest inof the state of the Rio Grande do Norte, Brazil. The Cchemical analyses had revealed ademonstrated text of total sugar rates of 65% and 49%, and proteins of 7.0% for in extracts of G. saccatum and P. dermoporus extracts, respectively. The analyses ofNMR spectroscopy of RMN had demonstrated that these extracts are composites forof a complex involving β- glucans and- proteins complex. The inhibition of the formation of superoxide radicals formation was of 88.4% in G. saccatum and 83.3% in P. dermoporus, and 75 and 100% for inhibition of hydroxyls radicals inhibition. TopicalThe topic application of extracts the 10, 30 and 50 mg/kg extract in BALBc mice with cutaneous inflammation induced byfor croton oil demonstrated to inhibitedion of ear edema of ear and cells polimorfonuclears cells atin the inflamed siteplace, being this reply more effective in lower concentrations being more effective. The evaluation of the glucans of G. saccatum and P. dermoporus glucans under induced pleurisy for carrageenan-induced pleurisya of showed the antiinflammatory action of these composites., being analyzed tThe frame number in the pleural exudates and thedosage of nitric oxide dosage was also analyzed. The cytotoxic action of these polymers was analyzed throughthrough the mitochondrial function (MTT). The incubation of the glucans with mononuclear cells of the peripheral blood demonstrated that the extracted glucans extracted fromof G. saccatum havepossess a moderate cytotoxic action. These results suggest that these mushrooms possess polymers formed byfor a complex glucana-protein complex, with antiinflammatory and antioxidant actions

Genes candidatos de suscetibilidade a pré-eclampsia: estudo de associação

Preeclampsia is a multifactorial disease of unknown etiology that features with wide clinical symptoms, ranging from mild preeclampsia to severe forms, as eclampsia and HELLP syndrome. As a complex disease, preeclampsia is also influenced by genetic and environmental factors. Aiming to identify preeclampsia susceptibility genes, we genotyped a total of 22 genetic markers (single nucleotides polymorphisms SNPs) distributed in six candidates genes (ACVR2A, FLT1, ERAP1, ERAP2, LNPEP e CRHBP). By a case-control approach, the genotypic frequencies were compared between normotensive (control group) and preeclamptic women. The case s group was classified according to the disease clinical form in: preeclampsia, eclampsia and HELLP syndrome. As results we found the following genetic association: 1) ACVR2A and preeclampsia; 2) FLT1 and severe preeclampsia; 3) ERAP1 and eclampsia; 4) FLT1 and HELLP syndrome. When stratifying preeclampsia group according to symptoms severity (mild and severe preeclampsia) or according to the time of onset (early and late preeclampsia), it was detected that early preeclampsia is strongly associated to risk preeclampsia, eclampsia and HELLP syndrome have different genetic bases, although FLT1 gene seems to be involved in preeclampsia and HELLP syndrome pathophisiology

Avaliação demográfica, clinico-laboratorial e genética de indivíduos com lupus eritematoso sistêmico e artrite reumatóide residentes em região tropical

The aetiology of autoimmunes disease is multifactorial and involves interactions among environmental, hormonal and genetic factors. Many different genes may contribute to autoimmunes disease susceptibility. The major histocompatibility complex (MHC) genes have been extensively studied, however many non-polymorphic MHC genes have also been reported to contribute to autoimmune diseases susceptibility. The aim of the present study was to evaluate the influence of SLC11A1 gene in systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). Ninety-six patients with SLE, 37 with RA and 202 controls enrolled in this case-control study, were evaluated with regard to demographic, genetic, laboratorial and clinical data. SLE mainly affects females in the ratio of 18 women for each man, 88,3% of the patients aged from 15 to 45 years old and it occurs with similar frequency in whites and mulattos. The rate of RA between women and men was 11:1, with 77,1% of the cases occurring from 31 to 60 years. The genetic analysis of the point mutation -236 of the SLC11A1 gene by SSCP did not show significant differences between alleles/genotypes in patients with SLE or RA when compared to controls. The most frequent clinical manifestations in patients with SLE were cutaneous (87%) and joint (84.9%). In patients with RA, the most frequent out-joint clinical manifestation were rheumatoid nodules (13,5%). Antinuclear antibodies were present in 100% of the patients with SLE. There was no significant relation between activity of disease and presence of rheumatoid factor in patients with RA, however 55,6% of patients with active disease presented positive rheumatoid factor. Significant association between alleles/genotypes of point mutation -236 and clinical manifestations was not found

Marcadores nutricionais e inflamatórios e sua associação com a morbimortalidade em hemodiálise

Background: Malnutrition, inflammation and comorbidities are frequent in patients with chronic renal failure in hemodialysis (HD), contributing for morbidity and mortality. Aims: To evaluate the correlation between anthropometric, laboratory parameters, bioelectrical impedance (BIA) and inflammatory markers with the morbidity and mortality of patients in HD, as well as the impact of its alterations throughout 12 months. Methods: 143 patients of a dialysis facility in Northeast Brazil were evaluated throughout 18 months. Patients with more than 3 months on dialysis, older than 18 years, without amputation of hands and feet, were included in the study. We performed a clinical (subjective global assessment - SGA), anthropometric (BMI, percent of ideal weight, MAC, MAMC, MAMA, percent of fat mass and TSF), laboratory (albumin, creatinine, lymphocyte count as nutritional markers and CRP, IL-6 and TNF- as inflammatory markers) evaluation and BIA (reactance, phase angle and percent of body cell mass) at the beginning of study and after 3, 6 and 12 months of follow-up. The association between study variables and deaths and hospitalizations in 6 and 12 months was investigated. The variable with significance < 10% in the univariate analysis had been enclosed in a multivariate logistic regression analysis. We also investigated the risk of mortality and hospitalization associated with differences in measurements of the variables at baseline and six months later. Results: Patients were aged 52.2 ± 16.6 years on the average, 58% were male, and mean dialysis vintage was 5.27 ± 5.12 years. The prevalence of malnutrition varied from 7.7-63.6%, according to the nutritional marker. The variables associated with morbidity and mortality in 6 and 12 months had been creatinine ≤ 9.45 mg/dl, phase angle ≤ 4.57 degrees, BMI ≤ 23 kg/m2, age ≤ 64.9 years, reactance ≤ 51.7 ohms; Charlson´s index ≥ 4 and socioeconomic status ≤ 7. During six months of follow up, decrease in albumin was associated with significantly higher mortality risk. Conclusions: This study detected that the best predictors of morbidity and mortality between nutritional and inflammatory markers are phase angle, reactance, creatinine and BMI and that changes in albumin values over six 107 months provide additional prognostic information. The authors believe that parameters of BIA may detect early changes in nutritional status and emphasize that longitudinal studies with larger number of patients are necessary to confirm these data and to recommend BIA as a routine nutritional evaluation in HD patients

Intervenção dietoterápica em portadores de lipodistrofia generalizada congênita do Rio Grande do Norte

Congenital generalized lipodystrophy is a rare genetic disease with autosomal recessive inheritance characterized by the generalized absence of subcutaneous adipose tissue and insulin resistance. The aim of our study was to determine the profile of patients with congenital generalized lipodystrophy (Berardinelli-Seip syndrome) through their clinical history, eating habits, and socioeconomic and cultural aspects; assess food consumption and nutritional status of the study group; propose and evaluate a diet therapy model associated to oral supplementation with zinc to help in the control and prevention of metabolic complications associated to the pathology. Initial assessment of food consumption indicated a voracious appetite in all the patients studied. The introduction of zinc reduced appetite, contributing to patient adherence to the food plan proposed. It was also observed that the proposed diet contributed mainly to glycidic control, specifically with respect to HbA1c. The nutritional status of the patients investigated was adequate in terms of body mass index (BMI), arm muscle circumference (AMC), arm muscle area AMA, but triceps skinfold (TSF) indicated serious malnutrition. Our study is unique in the literature and provides important information to the field of nutrition and to individuals with this pathology. Furthermore, it contemplates the interdisciplinary and multidisciplinary requirements of the Postgraduate Program in Health Sciences of the Federal University of Rio Grande do Norte (UFRN), Natal, Brazil

Determinação dos fatores neuroepidemiológicos das crises convulsivas em recém nascidos internados em unidades de terapia intensiva

O objetivo do nosso projeto foi determinar as características dos recém nascidos com crises convulsivas internados em unidades de terapia intensiva. Foi realizada uma pesquisa multicêntrica, observacional, prospectiva, cuja população alvo foi os recém nascidos com crises convulsivas internados em unidades de terapia intensiva, envolvendo equipe multidisciplinar constituída por neurologista infantil, neonatologistas, intensivistas pediátricos, enfermeiros, técnicos de enfermagem e fisioterapêutas. As crises foram definidas pelo critério clínico, com classificação de Volpe. Variáveis relacionadas à gestação, ao parto, características dos recém nascidos, aspectos das crises convulsivas e mortalidade foram analisadas. Estatística: descritiva (freqüências, medidas de tendência central e dispersão) e análise (teste de probabilidade, teste de risco e de acurácia). Comparamos as crises clínicas entre os recém nascidos de termo e pretermo e observamos diferenças com significância estatística na idade de início das crises, mais tardia nos prematuros, na etiologia predominante: hemorragia peri-intraventricular no prematuro e encefalopatia hipóxico-isquêmica no termo e tipo clínico de crise, clônica no pretermo e sutil no termo. Os testes de acurácia utilizados para determinar se o tipo clínico de crise convulsiva é predictor da etiologia da mesma não revelaram resultados positivos. Quanto às características associadas à mortalidade de prematuros com crise convulsiva, observamos associação entre ventilação mecânica e pneumonia com a mortalidade. Existem diferenças clínicas quando comparamos os recém nascidos pretermo e de termo com crises convulsivas, confirmando dados da literatura
