Remodelamento cardíaco: análise seriada e índices de detecção precoce de disfunção ventricular

FUNDAMENTO: A estenose aórtica supravalvar (EAo) é utilizada para o estudo da remodelação cardíaca (RC) por sobrecarga pressórica. Nesse modelo, não estão claramente estabelecidos o comportamento da RC desde a fase inicial, nem os melhores parâmetros para a identificação da disfunção ventricular. OBJETIVOS: 1) Caracterizar, precoce e evolutivamente, as modificações morfofuncionais durante a RC em ratos com EAo e 2) identificar o índice mais sensível para detecção do momento do aparecimento da disfunção diastólica e sistólica do ventrículo esquerdo (VE). MÉTODOS: Ratos Wistar foram divididos em dois grupos - controle (GC, n=13) e EAo (GEAo, n=24) - e estudados nas 3ª, 6ª, 12ª e 18ª semanas pós-cirurgia. Os corações foram analisados por meio de ecocardiograma (ECO). RESULTADOS: Ao final do experimento, as relações do VE, do ventrículo direito e dos átrios com o peso corporal final foram aumentadas no GEAo. O ECO mostrou que o átrio esquerdo sofreu uma remodelação significativa a partir da 6ª semana. No GEAo, a porcentagem de encurtamento endocárdico apresentou queda significativa a partir da 12ª semana e a porcentagem de encurtamento mesocárdico, na 18ª semana. A relação onda E e onda A (E/A) foi superior no GC em comparação ao GEAo em todos os momentos analisados. CONCLUSÕES: O ventrículo esquerdo dos ratos com EAo, durante o processo de remodelação, apresentou hipertrofia concêntrica, disfunção diastólica precoce e melhoria da função sistólica, com posterior deterioração do desempenho. Além disso, constatou-se que os índices ecocardiográficos mais sensíveis para a detecção da disfunção diastólica e sistólica são, respectivamente, a relação E/A e a porcentagem de encurtamento endocárdico.

Qualidade de vida de pacientes submetidos à radioterapia para tratamento de lesões malignas de cabeça e pescoço

In order to evaluate the quality of life of patients with head and neck cancer, this study analyzed data of 24 patients with squamous cell carcinoma, which indicated therapy was radiotherapy or not be combined with chemotherapy and surgery. The study was conducted in the Unit of Radiotherapy of Megavoltage located in the São José de Rio Preto-SP, in the period August 2007 to January 2008. Then, it was used the questionnaire of quality of life from University of Washington which enabled the identification of different quality of life patterns associated with the different stages of radiotherapy, indicating to be viable the prospect of recognition of prognostic factors of reduction in multiple domains of quality of life. From the data collected and analyzed, it was identified that the areas with the worst score in the begin of radiotherapy were appearance, speech and anxiety; during the treatment were taste, saliva and anxiety; and in the end were taste, saliva and swallowing. Throughout the treatment, it was observed the deterioration of patients' mood. In this regard, emphasizes the importance of dental and psychological follow-up, within the framework of a multidisciplinary care for patients with head and neck cancer during radiotherapy treatment.

Desempenho de crianças com deficiência auditiva e implante coclear em tarefas de seleção de e de nomeação de figuras

The aim of this study was to investigate the development of specific domains of Numerical Cognition (Number Sense – NS, Number Comprehension – NC, Number Production – NP, and Calculation – CA) in Brazilian children with Specific Learning Disorders. The study included 72 children (36 boys), from 9-to 10-years-old, enrolled in 4th and 5th years of elementary school of public schools at countryside of Sao Paulo State, Brazil. They were divided into three groups: control (CT, N = 42), Developmental Dyslexia (DL, N = 11) and Developmental Dyscalculia combined with dyslexia (DDc, N = 19). All participants had intellectual level within the normal range, however, children from the last two groups had Learning Disorders classified by School Achievement Test - TDE (Stein, 1994) and DDc children received necessarily classification as 'inferior' in Arithmetic Test of TDE. The children did not differ in NS. DL and DDc children showed slight deficits in NC. However, DDc children had moderate in NP and mild to moderate deficits in CA, which indicates a more generalized impairment in Numerical Cognition. Furthermore, DDc children showed discrepancy in Numerical Cognition performance when compared to the other groups. Thus, children with Learning Disorders showed different performances in Numerical Cognition, although both groups had preserved SN, DDc children showed higher deficits and discrepancy in relation DL and typically developing children.

Encoprese e intervenção psicológica: revisão de literatura

Studies have shown that encopresis, related to bowel control disorder, can bring significant impact for the individual life, such as low self-esteem and deficits in social interaction. Despite the significant impairment recognized that this disorder can have on child development, the scientific literature has given little attention to the theme, with a low number of publications on the subject. Thus, this paper investigated Brazilian publications in psychology related to encopresis between 1994 and 2013 in data base Lilacs and Scielo. 231 articles were found and were selected those that reported only intervention in encopresis. There were five articles and four published by the same journal and described behavioral interventions, and one author wrote three. The other one was psychoanalytic. The surveys were conducted with children and adolescents and behavioral interventions have been successful with remission of encopresis symptoms. The data affirm the deficiency in publications in the area and possibly limited number of psychologists investigating the issue, which is of significant importance.

Avaliação das áreas de conflito de uso em APP da microbacia do alto água fria, Bofete (SP)

The misuse of land by man and is causing serious problems to the environment, resulting in ecological imbalance and depletion of natural resources, especially when it comes to areas of permanent preservation, that ecosystems are essential for balance and water conservation importance . Conflicts of land use is a major cause of silting of rivers and water bodies, causing significant losses in soil and decaying natural water resources both in quantity and in quality. Within this scenario, the planning becomes essential for the control of environmental impacts to the environment factor. This study aimed to evaluate land use conflicts in permanent preservation areas of the stream Água Fria watershed, Bofete (SP) using Geographic Information System and satellite image of LANDSAT - 5 of 2010, scale 1:50000. The results show that 51.16% of the permanent preservation areas of the watershed are conflicting, especially for pasture (88.94%) and reforestation with eucalyptus (11.06%). The GIS IDRISI Selva and Cartalinx along with GIS techniques demonstrated speed and efficiency in identifying, measuring and editing maps of land use, preservation and ongoing conflicts in areas of permanent preservation.
