Atitudes de escrita em sala de aula: uma abordagem interacionista sócio-discursiva
Get PDFDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em Letras/LingüísticaA presente pesquisa analisa o desenvolvimento de atitudes de escrita em uma Quinta série do ensino fundamental, da rede pública de ensino. Este estudo verifica, primeiramente, a presença de gêneros textuais em sala de aula e na vida dos alunos, bem como os valores que eles atribuem ao ato de escrever. Em um segundo momento, a pesquisa assume as características de uma pesquisa-ação e propõe um trabalho cooperativo, conjunto, envolvendo a pesquisadora e a professora. Nesse segundo momento, o objetivo é inserir a produção de textos em sala de aula a fim de promover o desenvolvimento da habilidade de escrita dos alunos em um movimento de escrita e reescrita. O estudo visa também a enfocar o contexto de produção e a partir dos textos produzidos, analisar as suas características discursivas. O referencial teórico que fundamenta a análise é o interacionismo sócio-discursivo postulado pela equipe de Genebra: Bronckart (1999); Bronckart (2000); Bronckart & Stroumza (2000); Schneuwly (1994); Dolz & Schneuwly (1996); Dolz & Schneuwly (1997). Este estudo, ao assumir uma concepção (sócio) interacionista de linguagem e de desenvolvimento, dialoga com os postulados de Vygotsky (1996) e de Bakhtin (1995;1997). O trabalho desenvolvido, em sala de aula, em uma quinta série leva a escola a refletir sobre a importância de um trabalho de mediaçào doprofessor em classe e da intervenção nos processos de desenvolvimento dos aluno
Home versus in-centre haemodialysis for end-stage kidney disease
No full textBackgroundHome haemodialysis is associated with improved survival and quality of life in uncontrolled studies. However, relative benefits and harms of home versus in-centre haemodialysis in randomised controlled trials (RCTs) are uncertain.ObjectivesTo evaluate the benefits and harms of home haemodialysis versus in-centre haemodialysis in adults with end-stage kidney disease (ESKD).Search methodsThe Cochrane Renal Group's Specialised Register was searched up to 31 October 2014.Selection criteriaRCTs of home versus in-centre haemodialysis in adults with ESKD were included.Data collection and analysisData were extracted by two investigators independently. Study risk of bias and other patient-centred outcomeswere extracted. Insufficient data were available to conduct meta-analyses.Main resultsWe identified a single cross-over RCT (enrolling 9 participants) that compared home haemodialysis (long hours: 6 to 8 hours, 3 times/ week) with in-centre haemodialysis (short hours: 3.5 to 4.5 hours, 3 times/weeks) for 8 weeks in prevalent home haemodialysis patients. Outcome data were limited and not available for the end of the first phase of treatment in this cross-over study which was at risk of bias due to differences in dialysate composition between the two treatment comparisons.Overall, home haemodialysis reduced 24 hour ambulatory blood pressure and improved uraemic symptoms, but increased treatmentrelated burden of disease and interference in social activities. Insufficient data were available for mortality, hospitalisation or dialysis vascular access complications or treatment durability.Authors' conclusionsInsufficient randomised datawere available to determine the effects of home haemodialysis on survival, hospitalisation, and quality of life compared with in-centre haemodialysis. Given the consistently observed benefits of home haemodialysis on quality of life and survival in uncontrolled studies, and the low prevalence of home haemodialysis globally, randomised studies evaluating home haemodialysis would help inform clinical practice and policy

No full textObjectif : évaluer les résultats chirurgicaux et la surveillance d’une cohorte prospective de 132 patientes avec le diagnostic de carcinome canalaire in situ (CCIS) de bas grade à la biopsie, et envisager si une surveillance seule est possible. Matériels et méthodes : les patientes présentant un CCIS de bas grade pur diagnostiqué à la biopsie entre juin 1999 et novembre 2015 prises en charge à l’Hôpital René Huguenin ont été incluses. Nous avons recueilli prospectivement : les résultats chirurgicaux, et les données de suivi. Deux analyses univariées ont été réalisées: une entre les groupes CCIS de bas grade et CCIS de grade intermédiaire et haut, une entre les groupes des CCIS et des cancers infiltrants (CCI). Résultats : 132 patientes ont été incluses avec : 33 exérèses totales, 8 hyperplasies épithéliales atypiques et 91 carcinomes. Les carcinomes étaient : 81 CCIS purs et 10 CCI. Le taux de sous-diagnostic de CCI était de 7,6%. Le délai moyen de suivi était de 70,8 mois. La survie sans récidive à 15 ans était de 86%. La comparaison entre les groupes CCIS de bas grade et CCIS de grade intermédiaire et haut était significative pour : la taille du dispositif de prélèvement (p < 0,01), la modification des microcalcifications post-biopsie (p= 0,02), le nombre moyen de prélèvements par biopsie (p= 0,01). La comparaison entre les groupes CCIS et CCI était significative pour : l’âge (p = 0,03) et l’ACR (p<0,01). Conclusion : une surveillance seule semble envisageable pour les CCIS de bas grade
Depression and all-cause and cardiovascular mortality in patients on haemodialysis: A multinational cohort study
No full textBackground: Depression and early death are both common in adults with Stage 5 chronic kidney disease. Studies have shown an association between depression and total mortality, but the association between depression and cardiovascular death is less certain.Methods: We conducted a prospective multinational cohort study involving adults who were treated with long-term haemodialysis within a single dialysis network between April and November 2010. Depression was considered present when patients reported a Beck Depression Inventory (BDI) II score >= 14 at baseline. Sensitivity analyses considered a BDI II score >= 20 to identify moderate depression. Multivariable Cox proportional hazards regression was used to assess adjusted hazards for all-cause and cardiovascular mortality at 12 months.Results: Three thousand and eighty-six participants in the network received the BDI II questionnaire, and 2278 (73%) provided complete responses to the survey questions. Among these, 1047 (46%) reported depression. During a mean follow-up of 11 (standard deviation: 2.5) months (2096 person-years), we recorded 175 deaths, of which 66 were attributable to cardiovascular causes. Depression (BDI score >= 14) was not associated with all-cause mortality [adjusted hazard ratio: 1.26 (95% confidence interval: 0.93-1.71)] or cardiovascular mortality [0.82 (0.50-1.34)]. When a higher BDI score (BDI score >= 20) was used to identify moderate depression, depression was associated with total mortality [1.40 (1.02-1.93)] but not cardiovascular mortality [1.05 (0.63-1.77)].Conclusions: The association between depression and cardiovascular mortality in adults with kidney failure treated with haemodialysis is uncertain. Depression is a heterogeneous disorder and may only be a risk factor for premature death when at least of moderate severity
