Os enfermeiros e as representações sociais sobre o envelhecimento : implicações nos cuidados promotores da autonomia da pessoa idosa hospitalizada

RESUMO: O envelhecimento da população tende a aumentar em todo o mundo, trazendo consequências a níveis sociais, económicos, e de saúde. As hospitalizações e a necessidade de cuidados de enfermagem à população idosa tendencialmente aumentam pela maior fragilidade, derivada do aumento das situações de doença crónica e dependência. Os cuidados de enfermagem podem ser influenciados pelas representações sociais acerca do envelhecimento, estando associados mitos e estereótipos, e levar à desvalorização da individualidade e autonomia da pessoa idosa. Neste sentido, preconiza-se a realização de cuidados em parceria com a pessoa idosa, que promovam a sua autonomia e empowerment. Este estudo tem como objectivo compreender o modo como as representações sociais dos enfermeiros acerca do envelhecimento influenciam os cuidados de enfermagem na promoção da autonomia do idoso hospitalizado. Realizámos um estudo qualitativo, com recurso à entrevista e a técnica por associação livre de ideias, sendo entrevistados 17 enfermeiros de um serviço de internamento de medicina. Da análise dos resultados, constatámos que para os enfermeiros do estudo a representação social negativa acerca do envelhecimento foi a mais evidenciada, associada a situações como: dependência, doença, solidão, isolamento, necessidades, tristeza, peso na sociedade/problemas/dificuldades; levando à desvalorização das capacidades físicas, mentais, psicológicas, e da autonomia da pessoa idosa. Como factores dificultadores da promoção do respeito e autonomia da pessoa idosa referiram a motivação, características do enfermeiro e da pessoa idosa e os constrangimentos institucionais. Contudo alguns enfermeiros utilizam estratégias facilitadoras da promoção da autonomia como a: apresentação, proximidade, disponibilidade, promoção da esperança, avaliação da situação, e capacitação física e mental. Concluímos que as representações sociais negativas acerca do envelhecimento condicionam os cuidados de enfermagem na promoção da participação da pessoa idosa nos cuidados e nas decisões relativas a si. Os cuidados realizados em parceria, influenciados por uma visão positiva da pessoa idosa, valorizam a sua individualidade e toda a sua história de vida fomentando a sua autonomia.---------- ABSTRACT: Population aging is a global phenomenon, felt particularly in developed countries, with consequences at the social, economic and health-related levels. Hospitalization rates and nursing care needs among the elderly are on the rise in part due to the increased fragility of this population which experience greater levels of dependency and chronic disease. The quality of nursing care may be influenced by social representations of aging, associated with myths and stereotypes, that may lead to the devaluation of the individuality and autonomy of elderly persons. To this end, advocates for care in partnership with the elderly person, that promote their empowerment and autonomy. The present study aims to understand the manner in which social representations held by nurses with regards to the phenomenon of aging influence nursing care, with particular emphasis on the promotion of autonomy among hospitalized elderly patients. This study is a qualitative study, utilizing interviews and the free association of ideas technique, with a total of 17 interviews conducted on nurses working in a hospital ward. According to our results, nurses harbour negative social representations concerning the aging process, associating the latter with dependency, disease, loneliness, needs, sadness, burden on society/problems/difficulties, all of which may lead to the devaluation of the physical, mental, and psychological capacities of the elderly, negatively impacting upon their autonomy. Among those factors found to hinder the promotion of respect and autonomy of the elderly in this study, are personal motivation, characteristics of the nurse and the elderly person and institutional barriers. However, some nurses made use of a number of strategies that promoted patient autonomy, namely: presentation, proximity, availability, the promotion of hope, situation evaluation and physical and mental capacitation. In conclusion, negative social representations concerning aging condition the quality of nursing care, particularly, in what concerns the promotion of patient participation in care and self determination. Nursing interventions carried out in collaboration with the patient, influenced by a positive view of the elderly, value the individuality and life history of these individuals, thereby fomenting their autonomy

T cell Maturation and Regulatory T Cell Differentiation:From the Thymus to the Periphery

Immunological tolerance, that is, the failure to mount an immune response to an otherwise immunogenic molecule, is one of the fundamental questions in immunology. The fact that lymphocytes express antigen receptors that are generated randomly and have the potential to recognize any conceivable antigen, adds another puzzle to the physiology of immunological tolerance. The other side of the coin, the general absence of immune responses to self antigens, is ensured by a tight regulation and several selection steps during T and B cell differentiation. One of these processes is the differentiation of regulatory T cells (Treg). While developing in the thymus, T cell clones bearing receptors with high affinity/avidity to antigens present at the time of differentiation may be eliminated by apoptosis or, alternatively, express Foxp3 and become Treg. Treg are key players in the regulation of immunological tolerance since humans and mice with complete loss of function variants of this gene develop fatal autoimmune conditions early in life.(...)

Policies to improve the lives of Slum Dwellers – from international agreements to local contexts. The Brazilian case-study

Last decades economic development induced massive international and regional migration flows directed to the urban spaces. The magnitude and swiftness of these processes determined that several cities’ authorities would fail to respond to the increasing demands of many social services. The right to an “adequate housing” emerged as a political concern, leading governments and institutions to develop housing programmes directed to improve the lives of slum dwellers. This paper presents a diachronic evolution of these specific housing policies in the paradigmatic case-study of Brazil, critically analysing the evolving roles played by the multiple levels of decision (from international institutions to local communities) in the development and implementation of such measures.
