Giving continuation to the production of knowledge in nursing and seeking to contribute to the increase in the number of explanatory theories of the functional content of nurses, there is interest in answering the question: how can a middle-range theory in nursing be built that explains the nurse-elderly interaction in a successful aging process? As well, we address the goal of describing the process of building a middle-range theory in nursing. Middle-range theory refers to a qualitative paradigm study of inductive thinking, developed in the context of primary health care. The information was collected through participant observation and interviews. Method of analysis grounded theory by Corbin and Strauss(1) was followed, utilizing the triangulation of data and theoretical sampling.Grounded theory has become a method of analysis which facilitates the understanding and explanation of the phenomenon under study. By making clear the nature and process of the nurse-elderly interaction in the selected context and within the context of successful aging, a middle-range theory proposal emerged.

ResumoO objetivo deste estudo foi realizar uma revisão de literatura sobre as principais alterações que ocorrem no sistema respiratório após o Acidente Vascular Cerebral (AVC) e também sobre os efeitos de treino muscular respiratório nestes pacientes. A metodologia adotada foi a pesquisa de artigos através das bases de dados electrónicas (Pubmed, Scielo e Pedro) em língua portuguesa e inglesa relacionando os temas: alterações do sistema respiratório e métodos de avaliação e reabilitação da força muscular respiratória em indivíduos acometidos pelo AVC. Existe evidência científica de que indivíduos acometidos pelo AVC podem apresentar diminuição da força muscular inspiratória e expiratória. Estudos sugerem que o treino muscular respiratório, através de carga limiar, pode trazer benefícios quanto a melhora da função respiratória e da força dos músculos respiratórios. Porém, mais estudos devem ser realizados para o aprofundamento do conhecimento sobre os benefícios e efeitos a longo prazo da reabilitação respiratória em pacientes com AVC.

Focus-group is strongly associated with qualitative approaches, revealing an extraordinary usefulness in research due to their heuristic qualities. This systematic literature review allows assessment of the state-of-the-art regarding the application of focus group, and the results of these focus group studies, particularly in the context of nursing education. With an aim to analyse the utilization of focus group in the teaching-learning process in nursing, the following goals were set: to present the focus group as a method and technique of data collection; to identify advantages and limitations of its use in research as in the nursing teaching-learning processes. A systematic review of the literature was developed according to the PI(C)OD (Participants, Interventions, Comparisons, Outcomes, Design of the study) analysis protocol. From 598 available articles, twelve meeting the eligibility criteria were selected and analyzed. We found that in qualitative studies, the focus group is presented as a useful method and technique to look deeper into human phenomena, especially those related to the learning process and its principle players. Results corroborate the information provided by the specialized literature, e.g., the focus group technique/method is useful when the intention is to assess experiences, perceptions, opinions, beliefs, values and attitudes, as is the case within many facets of the nursing teaching process.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
