As possibilidades de enfrentamento da violência infantil na consulta de enfermagem sistematizada

A violência infantil vem crescendo e aos serviços de saúde compete lidar com este fenômeno. A CIPESC® é uma ferramenta sistematizadora do cuidado e pode visibilizar a violência infantil nas consultas de enfermagem. Este estudo buscou identificar os limites e potencialidades da CIPESC® na consulta de enfermagem com crianças vítimas de violência doméstica. Estudo descritivo, qualitativo, tipo estudo de caso, analisou 15 relatos por web-questionário de enfermeiros da atenção básica, da Secretaria Municipal de Curitiba, Paraná, sobre a ocorrência de violência. Embora a CIPESC® tenha mostrado potencialidades, os diagnósticos e intervenções existentes da nomenclatura não foram plenamente acionados pelos pesquisados. Apresentou limites preocupantes no que tange ao reconhecimento das necessidades e vulnerabilidades que envolvem o fenômeno da violência. Conclui-se que é preciso agregar à nomenclatura os atributos referentes à liberdade e autonomia, essenciais para o enfrentamento da violência, além de maneiras de intervir baseadas em evidências.

Paralisia cerebral tetraplégica e constipação intestinal: avaliação da reeducação intestinal com uso de massagens e dieta laxante

A constipação intestinal afeta 74% dos indivíduos com paralisia cerebral. O objetivo deste estudo foi avaliar resultados das intervenções de enfermagem no tratamento da constipação intestinal associada à paralisia cerebral. Trata-se de um estudo quantitativo, prospectivo e comparativo (antes-depois). A amostra foi composta por 50 pacientes com paralisia cerebral tetraplégica e constipação intestinal. As principais orientações conservadoras foram: consumo diário de alimentos laxantes e óleos vegetais, aumento da ingestão hídrica e execução de manobras intestinais diárias. Houve alívio total ou parcial da constipação em 90% dos participantes, com melhora de aspectos da qualidade de vida, como sono, apetite e irritabilidade, além de diminuição significativa de sangramento retal, fissura anal, retenção voluntária de fezes, choro e dor ao evacuar. Apenas 10% necessitaram de medicações laxantes. Recomenda-se que medidas conservadoras sejam preferencialmente utilizadas para o tratamento da constipação intestinal associada à paralisia cerebral e que medicamentos sejam apenas adjuvantes, quando necessário.

A Música Como Recurso Pedagógico Na Educação Pré – Escolar: Jardim Infantil da Aldeia SOS São Domingos

Reconhecendo a importância da música na educação pré-escolar e pensando na música como um recurso pedagógico e não como um instrumento que oferece ocupações às crianças dicidimos fazer um trabalho de pesquisa que tem como objectivo identificar se a música na educação pré-escolar pode ser um recurso pedagógico, que representa um magnífico auxílio aos educadores no processo ensino-aprendizagem. A pesquisa foi levada a cabo por meio de bibiografias (componente teórica), observações, actuações, questionários (componente prática) que, respondidos pelas educadoras da educação pré-escolar, foram avaliadas diferentes ideias de várias educadoras com formação e em formação no ramo da educação pré-escolar. O resultado da pesquisa indica que a música é importante na apredizagem da criança, que pode ser utilizada perfeitamente pelos educadores como recurso pedagógico eficiente e eficaz, fazendo com que as crianças expressem seus sentimentos, emoções, facilitando a aprendizagem e a socialização.

Absence of intestinal PPARγ aggravates acute infectious colitis in mice through a lipocalin-2-dependent pathway.

To be able to colonize its host, invading Salmonella enterica serovar Typhimurium must disrupt and severely affect host-microbiome homeostasis. Here we report that S. Typhimurium induces acute infectious colitis by inhibiting peroxisome proliferator-activated receptor gamma (PPARγ) expression in intestinal epithelial cells. Interestingly, this PPARγ down-regulation by S. Typhimurium is independent of TLR-4 signaling but triggers a marked elevation of host innate immune response genes, including that encoding the antimicrobial peptide lipocalin-2 (Lcn2). Accumulation of Lcn2 stabilizes the metalloproteinase MMP-9 via extracellular binding, which further aggravates the colitis. Remarkably, when exposed to S. Typhimurium, Lcn2-null mice exhibited a drastic reduction of the colitis and remained protected even at later stages of infection. Our data suggest a mechanism in which S. Typhimurium hijacks the control of host immune response genes such as those encoding PPARγ and Lcn2 to acquire residence in a host, which by evolution has established a symbiotic relation with its microbiome community to prevent pathogen invasion.

The role of SGLT1 and GLUT2 in intestinal glucose transport and sensing.

Intestinal glucose absorption is mediated by SGLT1 whereas GLUT2 is considered to provide basolateral exit. Recently, it was proposed that GLUT2 can be recruited into the apical membrane after a high luminal glucose bolus allowing bulk absorption of glucose by facilitated diffusion. Moreover, SGLT1 and GLUT2 are suggested to play an important role in intestinal glucose sensing and incretin secretion. In mice that lack either SGLT1 or GLUT2 we re-assessed the role of these transporters in intestinal glucose uptake after radiotracer glucose gavage and performed Western blot analysis for transporter abundance in apical membrane fractions in a comparative approach. Moreover, we examined the contribution of these transporters to glucose-induced changes in plasma GIP, GLP-1 and insulin levels. In mice lacking SGLT1, tissue retention of tracer glucose was drastically reduced throughout the entire small intestine whereas GLUT2-deficient animals exhibited higher tracer contents in tissue samples than wild type animals. Deletion of SGLT1 resulted also in reduced blood glucose elevations and abolished GIP and GLP-1 secretion in response to glucose. In mice lacking GLUT2, glucose-induced insulin but not incretin secretion was impaired. Western blot analysis revealed unchanged protein levels of SGLT1 after glucose gavage. GLUT2 detected in apical membrane fractions mainly resulted from contamination with basolateral membranes but did not change in density after glucose administration. SGLT1 is unequivocally the prime intestinal glucose transporter even at high luminal glucose concentrations. Moreover, SGLT1 mediates glucose-induced incretin secretion. Our studies do not provide evidence for GLUT2 playing any role in either apical glucose influx or incretin secretion.

Regional variations in ABC transporter expression along the mouse intestinal tract.

The ATP-binding cassette (ABC) family of proteins comprise a group of membrane transporters involved in the transport of a wide variety of compounds, such as xenobiotics, vitamins, lipids, amino acids, and carbohydrates. Determining their regional expression patterns along the intestinal tract will further characterize their transport functions in the gut. The mRNA expression levels of murine ABC transporters in the duodenum, jejunum, ileum, and colon were examined using the Affymetrix MuU74v2 GeneChip set. Eight ABC transporters (Abcb2, Abcb3, Abcb9, Abcc3, Abcc6, Abcd1, Abcg5, and Abcg8) displayed significant differential gene expression along the intestinal tract, as determined by two statistical models (a global error assessment model and a classic ANOVA, both with a P < 0.01). Concordance with semiquantitative real-time PCR was high. Analyzing the promoters of the differentially expressed ABC transporters did not identify common transcriptional motifs between family members or with other genes; however, the expression profile for Abcb9 was highly correlated with fibulin-1, and both genes share a common complex promoter model involving the NFkappaB, zinc binding protein factor (ZBPF), GC-box factors SP1/GC (SP1F), and early growth response factor (EGRF) transcription binding motifs. The cellular location of another of the differentially expressed ABC transporters, Abcc3, was examined by immunohistochemistry. Staining revealed that the protein is consistently expressed in the basolateral compartment of enterocytes along the anterior-posterior axis of the intestine. Furthermore, the intensity of the staining pattern is concordant with the expression profile. This agrees with previous findings in which the mRNA, protein, and transport function of Abcc3 were increased in the rat distal intestine. These data reveal regional differences in gene expression profiles along the intestinal tract and demonstrate that a complete understanding of intestinal ABC transporter function can only be achieved by examining the physiologically distinct regions of the gut.

Drosophila intestinal response to bacterial infection: activation of host defense and stem cell proliferation.

Although Drosophila systemic immunity is extensively studied, little is known about the fly's intestine-specific responses to bacterial infection. Global gene expression analysis of Drosophila intestinal tissue to oral infection with the Gram-negative bacterium Erwinia carotovora revealed that immune responses in the gut are regulated by the Imd and JAK-STAT pathways, but not the Toll pathway. Ingestion of bacteria had a dramatic impact on the physiology of the gut that included modulation of stress response and increased stem cell proliferation and epithelial renewal. Our data suggest that gut homeostasis is maintained through a balance between cell damage due to the collateral effects of bacteria killing and epithelial repair by stem cell division. The Drosophila gut provides a powerful model to study the integration of stress and immunity with pathways associated with stem cell control, and this study should prove to be a useful resource for such further studies.
