Atividades socialmente empreendedoras na enfermagem: contribuições à saúde/viver saudável / Socially entrepreneurial activities in nursing: contributions to health/healthy living / Actividades socialmente emprendedoras en enfermería: contribuciones a la salud/la vida saludable

Objetivo: Conhecer as contribuições de atividades socialmente empreendedoras da enfermagem à saúde de mulheres de uma Associação de Materiais Recicláveis. Métodos: Pesquisa exploratória, descritiva, de abordagem qualitativa, realizada entre julho e dezembro/2014 com 12 mulheres de uma Associação de Materiais Recicláveis, do Rio Grande do Sul. Os dados coletados antes e após as atividades, por meio de entrevista semiestruturada e observação participante, foram submetidos à análise de conteúdo. Resultados: Identificaram-se as categorias: da invisibilidade à necessidade de estímulo à saúde e viver saudável - processo dinâmico e complexo de superações diárias; da ausência de estímulo à saúde e viver saudável - o desejo de sentir-se cuidada; contribuições das atividades no estímulo do viver saudável - o significado de "sentir-se gente". Conclusão: as atividades desenvolvidas por meio do empreendedorismo social com as mulheres mostraram-se potencializadoras de autoestima, saúde/viver saudável na realidade investigada.

Objective: To know the contributions of socially entrepreneurial activities in Nursing to women participating in an Association of Recyclable Materials.Methods:An exploratory and descriptive study with a qualitative approach was conducted between July and December 2014, including 12 women participating in an Association of Recyclable Materials, in Rio Grande do Sul state, Southern Brazil. Data were collected before and after the activities, through semi-structured interviews and participant observations, and submitted to content analysis.Results:The following categories were identified: From invisibility to the need of health and healthy living - a dynamic and complex process of daily overcoming; From the lack of encouragement to health and healthy living - the desire to feel cared of; Contributions of activities to the promotion of healthy living - the meaning of 'feeling like a person'.Conclusion:The activities developed through social entrepreneurship with women enhanced their self-esteem and health/healthy living in the context analyzed.

Quantitative analysis of cardiac lesions in chronic canine chagasic cardiomyopathy

Lesions observed in chronic chagasic cardiopathy frequently produce electrocardiographic alterations and affect cardiac function. Through a computerized morphometrical analysis we quantified the areas occupied by cardiac muscle, connective and adipose tissues in the right atrium of dogs experimentally infected with Trypanosoma cruzi. All of the infected dogs showed chronic myocarditis with variable reduction levels of cardiac muscle, fibrosis and adipose tissue replacement. In the atrial myocardium of dogs infected with Be78 and Be62 cardiac muscle represented 34 and 50 percent, fibrosis 28 and 32 percent and adipose tissue 38 and 18 percent, respectively. The fibrosis observed was both diffuse and focal and mostly intrafascicular, either partially or completely interrupting the path of muscle bundles. Such histological alterations probably contributed to the appearance of electrocardiographic disturbances verified in 10 out 11 dogs which are also common in human chronic chagasic cardiopathy. Fibrosis was the most important microscopic occurrence found since it produces rearrangements of collagen fibers in relation to myocardiocytes which causes changes in anatomical physiognomy and mechanical behavior of the myocardium. These abnormalities can contribute to the appearance of cardiac malfunction, arrythmias and congestive cardiac insufficiency as observed in two of the analyzed dogs. Strain Be78 caused destruction of atrial cardiac muscle higher than that induced by strain Be62
