Da leitura à escrita: as estratégias de compreensão leitora na melhoria da escrita de textos narrativos

Relatório de Estágio apresentado à Escola Superior de Educação de Lisboa para obtenção do grau de mestre em Ensino dos 1.º e 2.º Ciclos do Ensino BásicoO presente relatório foi desenvolvido no âmbito da unidade curricular Prática de Ensino Supervisionada II do plano de estudos do Mestrado em Ensino dos 1.º e 2.º Ciclo do Ensino Básico. Pretende-se que este seja um documento reflexivo e fundamentado sobre a prática desenvolvida com uma turma do 2.º ano de escolaridade de uma Instituição Privada de Solidariedade Social da freguesia de São Domingos de Benfica. O mesmo debruça-se ainda sobre uma investigação realizada focada no papel da leitura no processo de ensino e de aprendizagem da escrita de textos narrativos. O objetivo deste estudo é compreender o impacto da utilização de estratégias de compreensão leitora na melhoria das produções de textos narrativos. O trabalho realizado iniciou-se num período de observação, durante o qual se procedeu à caracterização do contexto socioeducativo. Esta caracterização permitiu identificar as potencialidades e fragilidades da turma que conduziram à definição da problemática, dos objetivos gerais e de um plano de intervenção. Este deu sentido à prática, pelo que será alvo de análise no presente relatório. A intervenção enquadrou-se numa metodologia com características da investigação-ação, num paradigma qualitativo. Os resultados revelaram que os objetivos gerais definidos foram concretizados e que o recurso a estratégias de compreensão leitora contribuiu para o progresso dos alunos na escrita de textos narrativos.ABSTRACT The present report was developed as part of the course Prática de Ensino Supervisionada II of the study plan of the Master in Education in the 1st and 2nd cycle. This document is intended to be reflexive and reasoned on the practice developed with a class of the 2nd year of a Private Institution of Social Solidarity in the São Domingos de Benfica's parish. Furthermore, this report is based on a research focused in the purpose of the reading in the teaching process and on learning of narrative texts. The aim of this study is to understand the impact of using reading comprehension strategies in the improvement of the narrative texts production. This work started in an observation period, where the characterization of the social-educational context was performed. This characterization allowed identifying the potential and weakness of the class that led to the definition of the problem, the general objectives and the intervention plan. This plan are going to be analyzed in the current report, because it gave meaning to the practice. The intervention is based on a methodology with investigation-action characteristics, in a qualitative paradigm. The results showed that the defined general objectives were achieved and that the use of reading comprehension strategies contributed to the students’ progress in the writing of narrative texts

Avaliação por RM do efeito da viscossuplementação com ácido hialurónico na osteoartrose do joelho

A patologia reumatismal é hoje uma das queixas mais frequentes dos doentes no consultório de Medicina Geral e Familiar, condicionando um maior ou menor grau de incapacidade física no indivíduo afetado, que se manifesta por uma relativa dificuldade de integração na vida social, com evidente compromisso da vida pessoal e familiar. O aumento da prevalência da Osteoartrose com envelhecimento, juntamente com os dados demográficos do envelhecimento da população, faz da Osteoartrose um problema de saúde de elevada prioridade . A Osteoartrose do joelho é a maior causa de dor e incapacidade das pessoas idosas. São várias as condições que predispõem determinado indivíduo para o desenvolvimento desta patologia. Com toda a sua complexidade estrutural e com a importância que desempenha no movimento humano, rapidamente se depreende a imensidão de lesões que esta articulação pode sofrer e o impacto que as mesmas vão ter sobre a vida diária dos doentes. Não existem tratamentos que permitam parar ou inverter em definitivo um processo de Osteoartrose. No entanto, a adequada elaboração de um protocolo terapêutico permite prevenir, ou mesmo corrigir, alterações da troficidade e da morfologia articulares e, consequentemente, aliviar os sintomas, prolongar no tempo a capacidade funcional, minimizar o agravamento decorrente da progressão da doença e melhorar a qualidade de vida. O procedimento viscossuplementação com ácido hialurónico oferece uma perspetiva de uma outra abordagem terapêutica na Osteoartrose, apresentando benefícios para a dor e função, e também altera favoravelmente o curso da doença, melhorando quantitativamente e qualitativamente a cartilagem articular

A transição da vida ativa para a reforma

Dissertação de Mestrado em Gerontologia SocialO prolongamento da vida tem ultrapassado as expectativas anteriormente traçadas e os percursos de vida individuais evoluem e adaptam-se a estas novas transformações. A passagem à reforma é um acontecimento que envolve mudanças em diversos aspetos da vida do indivíduo e consequentes adaptações, que implicam uma nova reorganização dos padrões de vida individuais e restruturação de novos papéis sociais. O objetivo principal do presente trabalho é analisar as vivências da transição da vida ativa para a reforma, através da experiência de indivíduos que estão reformados. Para além da fundamentação teórica, o presente trabalho engloba uma investigação com recurso ao método qualitativo através de entrevistas em profundidade. Das conclusões deste estudo podemos destacar que a generalidade dos entrevistados transmite uma grande satisfação com as vivências na reforma, apesar de numa primeira fase, experienciarem um misto de sentimentos de ansiedade, solidão e tranquilidade provocados pelas diferentes entradas na reforma, sentimentos esses que são ultrapassados através de suporte familiar e social. Também se constatou que não foi realizada uma preparação para a reforma por todos os entrevistados devido à não existência ou privação das escassas medidas fornecidas pelo poder público e empresarial.The Increase of life expectancy has exceeded the previously drawn expectations. Due to this, the individual life paths have evolved and have adapted to these new transformations. The transition to retirement is a process that involves changes in several aspects of the individual's life and consequent adaptations. These aspects imply a new reorganization of individual living standards and restructuring of new social roles. The main objective of this paper is to analyze the experiences of the transition from active life into retirement, through the experience of retired people. In addition to the theoretical basis, the present work presents an investigation using the qualitative method. The conclusion of this study indicates that it is possible to emphasize that the generality of the interviewed people conveys great satisfaction with the experiences during the retirement period. However, in a first phase, they experience a mixture of feelings of anxiety, loneliness and tranquility, caused by the different phases in the retirement period. Through family and social support, it was possible to overcome some of these feelings. It was also found that all the interviewed people were not prepared for retirement, due to the inexistence or scarce measures provided by the public and business authorities.N/

Specifically, the role of the proinflammatory soluble CD40 ligand (sCD40L) on the expression of chronic coronary syndrome (CCS) is not completely understood. We evaluated whether sCD40L expression is associated with the presence of CCS and with the clinical and anatomical severity of CCS. Methods: We prospectively recruited 94 participants, assigned to two groups matched by age and sex, without coronary artery disease (n=26) and with CCS (n=68). Clinical, laboratory and anatomical data were prospectively collected, and serum levels of sCD40L were measured. Results: In patients with CCS, classic cardiovascular risk factors were more prevalent, and the sCD40L levels, leukocyte and neutrophil counts, and neutrophil/lymphocyte ratio, but not the C-reactive protein levels, were significantly higher than those in controls. sCD40L was independently associated with the presence of obstructive coronary artery disease in multivariate analysis. Regarding CCS severity, sCD40L levels showed a significant stepwise increase with increasing angina severity (ANOVA P=0.001). In addition, sCD40L was independently associated with the anatomical severity of coronary artery disease, as assessed by the Gensini score. Among patients with CCS, those with previous coronary artery bypass grafting (n=23) had lower sCD40L levels than patients waiting for revascularization (n=45) [4.3 (2.1) ng/mL vs. 6.8 (3.5) ng/mL, P=0.001]. Conclusions: The expression of the proinflammatory sCD40L was associated with the presence of CCS and reflected the clinical and anatomical severity of CCS. In addition, we describe for the first time the association between prior CABG and reduced sCD40L levels in patients with CCS.publishersversionpublishe

The proinflammatory soluble CD40 ligand is associated with the systemic extent of stable atherosclerosis

Funding: T.P. has received research support from Fundação para a Ciência e Tecnologia, Portugal [Project UID/BIO/04565/2020], and Programa Operacional Regional de Lisboa 2020 [Project N. 007317].Background and objectives: Polyvascular atherosclerosis is frequent and associated with a high cardiovascular risk, although the mechanisms regulating the atherosclerosis extent to single or multiple arterial territories are still poorly understood. Inflammation regulates atherogenesis and soluble CD40 ligand (sCD40L) is an inflammatory mediator associated with the presence of single-territorial atherosclerosis. We assessed whether the sCD40L expression is associated with the atherosclerosis extent to single or multiple arterial territories and with the atherosclerosis severity in different territories. Materials and Methods: We prospectively enrolled 94 participants with no atherosclerosis (controls, n = 26); isolated coronary atherosclerosis (group 1, n = 20); coronary and lower extremity (LE) atherosclerosis (group 2, n = 18); coronary and carotid atherosclerosis (group 3, n = 12); and coronary, LE, and carotid atherosclerosis (group 4, n = 18). Serum sCD40L levels were quantified. Results: The sCD40L levels (ng/mL, mean (standard deviation)) were 4.0 (1.5), 5.6 (2.6), 7.2 (4.2), 5.9 (3.7), and 5.1 (2.4) in controls and groups 1 to 4, respectively (ANOVA p = 0.012). In nonrevascularized patients, the sCD40L levels were significantly higher in group 2 than in group 1 and were correlated with the number of LE diseased segments. Prior LE bypass surgery was associated with lower sCD40L levels. Coexistence of coronary and LE atherosclerosis was independently associated with the sCD40L levels. Conclusions: The sCD40L levels were increased in stable atherosclerosis, particularly in polyvascular coronary and LE atherosclerosis. The number of LE diseased segments and prior LE revascularization were associated with sCD40L expression. To our knowledge, these are novel data, which provide insights into the mechanisms underlying multi-territorial atherosclerosis expression. sCD40L may be a promising noninvasive tool for refining the stratification of the systemic atherosclerotic burden.publishersversionpublishe

Quando o Intervalo QT é Curto Demais: Síncope Causada por Síndrome QT Curto

We report the case of a 52-year-old man who presented to our emergency department (ED) after three episodes of syncope in the seven hours before admission. During his stay in the ED he had recurrent ventricular tachycardia (VT) requiring external electrical cardioversion. A 12-lead electrocardiogram (ECG) showed a short QT (SQT) interval (270 ms, QTc 327 ms), with frequent R-on-T extrasystoles triggering sustained polymorphic VT. After exclusion of other precipitating causes, the patient was diagnosed as having SQT syndrome (SQTS) according to the Gollob criteria. To our knowledge, this is the first known documentation of an SQT-caused arrhythmic episode on a 12-lead ECG, as well as the first reported case of SQTS in Portugal. The patient received an implantable cardioverter-defibrillator and was discharged. At a follow-up assessment 14 months later he was symptom-free, interrogation of the device showed no arrhythmic events, and the ECG showed a QT interval of 320 ms (QTc 347 ms)

Modification of Zirconia implant surfaces by Nd:YAG laser grooves: does it change cell behavior?

The aim of this study was to evaluate gingival fibroblasts and human osteoblasts’ response to textured Nd:YAG laser microgrooves, with different dimensions, on zirconia implant surfaces. A total of 60 zirconia disks (8 mm in diameter and 2 mm in thickness) were produced and divided between four study groups (N = 15): three laser-textured (widths between 125.07 ± 5.29 μm and 45.36 ± 2.37 μm and depth values from 50.54 ± 2.48 μm to 23.01 ± 3.79 μm) and a control group without laser treatment. Human osteoblasts and gingival fibroblasts were cultured on these surfaces for 14 days. FEG-SEM (Field Emission Gun–Scanning Electron Microscope) images showed cellular adhesion at 24 h, with comparable morphology in all samples for both cell types. A similar cell spreading within the grooves and in the space between them was observed. Cell viability increased over time in all study groups; however, no differences were found between them. Additionally, proliferation, ALP (Alkaline phosphatase) activity, collagen type I, osteopontin and interleukin levels were not significantly different between any of the study groups for any of the cell types. Analysis of variance to compare parameters effect did not reveal statistically significant differences when comparing all groups in the different tests performed. The results obtained revealed similar cell behavior based on cell viability and differentiation on different microtopographic laser grooves, compared to a microtopography only established by sandblasting and acid-etching protocol, the reference surface treatment on zirconia dental implants.This work was endorsed by FCT project POCI-01-0145-FEDER-030498—Portugal, by FEDER funds through the COMPETE 2020—Programa Operacional Competitividade e Internacionalização and ImpHib—Development of advanced Hybrid Implants—NORTE-01-0247-FEDER-034074
