Dificuldades de aprendizagem em alunos do 3º ano duma escola pública do Estado de Alagoas, Brasil : uma visão da psicoeducação.

Enquadramento: A par da não alfabetização e do abandono escolar, as taxas de insucesso no ensino fundamental no Brasil atingem indicadores preocupantes. A aprendizagem é um processo complexo e são múltiplos os fatores que contribuem tanto positivamente quanto negativamente na aprendizagem dos alunos e os seus efeitos irão refletir-se no futuro dos educandos. Se há crianças com distúrbios fisiopatológicos que prejudicam a sua aprendizagem, noutras, porém, as dificuldades surgem por influência da escola/professores e da relação destes com a família Objetivos: Identificar as áreas de dificuldades de aprendizagem na componente curricular de português e matemática; identificar as dificuldades nos domínios de aprendizagem de cada área e analisar a relação das variáveis sociodemográficas e escolares com as dificuldades de aprendizagem. Material e métodos: Estudo exploratório-descritivo, quantitativo e correlacional numa amostra de 178 alunos, do 3º ano, numa escola pública de Taquarana, Alagoas, Brasil. Utilizamos um questionário para a caraterização socio demográfica e escolar dos alunos e uma escala utilizada na escola para a avaliação formal da aprendizagem. Resultados: Os participantes são na maioria do sexo masculino (55,6%) com uma média de idades de 8,53 anos, distribuídos em 6 turmas (3 manhã e 3 tarde) em que a menor tem 25 alunos e a maior tem 35. Demoram em média 20 minutos na deslocação para a escola. Verificamos que 34,3% vivem com pais solteiros, separados divorciados ou viúvos. 31,5% dos alunos referem ter muito mau, ou mau ambiente familiar e há turmas onde isso é mais evidente. Os pais dos alunos em 37,1% não têm instrução e em 53,4% não ajudam nos estudos ou trabalhos de casa. Os alunos que já reprovaram são 26,4% e destes, 36,2% já reprovaram 3 ou mais vezes. As dificuldades de aprendizagem em língua portuguesa e matemática são maiores nos alunos mais velhos, do sexo masculino e que já reprovaram mais de uma vez. Um ambiente familiar mau/muito mau e a situação familiar dos pais a falta de instrução dos pais e o não ajudarem nas tarefas de casa contribui com as dificuldades. Na língua portuguesa há maior dificuldade no respeitar o momento de escuta e fala, na leitura e interpretação, produção textos e uso das regras ortográficas. Em matemática globalmente têm maiores dificuldades sobressaindo os parâmetros de identificação das operações nas situações-problemas e elaboração de tabelas e gráficos. Conclusões: Encontramos no nosso estudo alunos com grandes taxas de reprovações e com dificuldades evidentes tanto na língua portuguesa como em matemática. Constatamos que diversos são os fatores que contribuem para o aparecimento das dificuldades na aprendizagem de alguns alunos mas não podemos deixar de refletir sobre a influência da família. A destruturação familiar, mau ambiente e o fato de não terem instrução e não ajudarem os filhos nos estudos mostraram-se influenciadores no insucesso dos alunos PALAVRAS-CHAVE – Aprendizagem, Dificuldades de aprendizagem, Família, Educação.

Complex genetic findings in a female patient with pyruvate dehydrogenase complex deficiency: Null mutations in the PDHX gene associated with unusual expression of the testis-specific PDHA2 gene in her somatic cells

Human pyruvate dehydrogenase complex (PDC) catalyzes a key step in the generation of cellular energy and is composed by three catalytic elements (E1, E2, E3), one structural subunit (E3-binding protein), and specific regulatory elements, phosphatases and kinases (PDKs, PDPs). The E1α subunit exists as two isoforms encoded by different genes: PDHA1 located on Xp22.1 and expressed in somatic tissues, and the intronless PDHA2 located on chromosome 4 and only detected in human spermatocytes and spermatids. We report on a young adult female patient who has PDC deficiency associated with a compound heterozygosity in PDHX encoding the E3-binding protein. Additionally, in the patient and in all members of her immediate family, a full-length testis-specific PDHA2 mRNA and a 5′UTR-truncated PDHA1 mRNA were detected in circulating lymphocytes and cultured fibroblasts, being bothmRNAs translated into full-length PDHA2 and PDHA1 proteins, resulting in the co-existence of both PDHA isoforms in somatic cells.Moreover, we observed that DNA hypomethylation of a CpG island in the coding region of PDHA2 gene is associatedwith the somatic activation of this gene transcription in these individuals. This study represents the first natural model of the de-repression of the testis-specific PDHA2 gene in human somatic cells, and raises some questions related to the somatic activation of this gene as a potential therapeutic approach for most forms of PDC deficiency.

The influence of reading direction on hemianopic reading disorders.

Hemianopic reading impairment is a consequence of a visual field defect to either the right or the left side and is characterized by an increased reading time and reduced reading performance. Depending on the side of the visual field defect, reading will be affected differently: Patients suffering from a visual field defect to the right side have noticeable difficulties in reading fluently with slowing. Patients suffering from a visual field defect to the left usually struggle to find the beginning of a line and read more fluently. It was suggested in the literature that changing the reading direction from horizontal to vertical may be a training strategy to reduce reading problems in patients with hemianopia. The aim of the study was to investigate the influence of reading direction on reading speed in patients with left- or right-sided visual field defects and in healthy controls. METHOD In 13 patients with hemianopia and in 13 age-matched controls, reading speed was calculated for texts in standard as well as in clockwise rotated orientation of 90, 180, and 270°. RESULTS In both groups, text rotation reduced reading speed compared to standard reading. Patients with left-sided hemianopia had the greatest reduction after text rotation. Patients with right-sided hemianopia had the smallest speed reduction in 90° vertically rotated texts. CONCLUSIONS Text rotation has different effects in left- or right-sided hemianopia patients. For patients with left-sided heminanopia, rotation of the text may not be a helpful training strategy, for right-sided hemianopia vertical rotation of the text of 90° may be a beneficial training strategy to reduce reading deficits.
