Using transparent specimens with a dual color injection, microscopy, and computer tomography, this report shows that the right and left ventricular subendocardial Purkinje networks are connected by an extensive septal network in the bovine heart. The septal network is present along the entire septum except at a free zone below ventricular valves. Being the only communication of the basal right septum with the right free wall, the supraventricular crest is an enigmatic but not, by any means, hidden muscular structure. It is one of the last structures to be activated in human heart. It is shown here that the supraventricular crest Purkinje network connects the anterosuperior right ventricular basal free wall Purkinje network to anterior right ventricular basal septal Purkinje network. It is suggested that the stimulus initiated at middle left ventricular endocardium will activate the supraventricular crest. The intraseptal connection found between the basal left ventricular subendocardial septal Purkinje network and the right ventricular basal septal Purkinje network is, probably, the pathway for the stimulus. An anatomic basis is provided to explain why the inflow tract contracts earlier than the outflow tract in the right ventricle systole. Anat Rec, 2017. © 2017 Wiley Periodicals, Inc.

Objective: to compare the sociodemographic and economic characteristics of the older adults in the community according to the living arrangement and to verify the association between the type of living arrangement and the quality of life scores. Method: a cross-sectional epidemiological study conducted with 796 older adults in the community. To assess quality of life (dependent variable), network and social support (adjustment variable), validated and applied chi-square tests, descriptive statistical analysis, multiple comparison analysis (ANOVA) and multiple linear regression model (p<0.05) were used. Results: the older adults who lived only with their spouses had better quality of life scores in all domains and facets, except in the death and dying domain, which did not show any significant difference. The lowest scores for quality of life were identified in the groups with the presence of children and, exceptionally, in the domain of social relationships and, in the facets death and dying and intimacy, those who lived alone had worse assessments. In the adjusted model, there was an association between the type of living arrangement and the different domains and facets of quality of life. Conclusion: living arrangement was associated with quality of life scores for older adults in the community, even after adjusting for the gender, age, number of morbidities, and social support variables.

<p>Objetivo: relatar a experiência do uso de uma metodologia ativa no estágio supervisionado na Atenção Primária à Saúde. Método: trata-se de um relato de experiência sobre o uso de uma metodologia ativa no estágio supervisionado, realizado entre março e junho de 2019, baseado nos pressupostos da educação problematizadora de Paulo Freire. Como estratégia pedagógica utilizou-se a Metodologia da Problematização, apoiada no Arco de Maguerez. Resultados: o Arco de Maguerez possibilitou implantar ações de educação em saúde na sala de vacina da unidade de saúde. Este processo de ensino-aprendizagem viabilizou uma postura ativa das acadêmicas envolvidas, convergiu para o propósito de facilitação da professora e resultou na efetiva implementação das estratégias planejadas durante a execução do Arco. Conclusão: o presente relato expôs uma experiência exitosa no âmbito do ensino-aprendizagem, de forma a protagonizar o papel das acadêmicas, em consonância com as diretrizes curriculares que indicam prática pedagógica ética, reflexiva e transformadora.</p><p>Descritores: Atenção Primária à Saúde.

Scientific knowledge in Brazilian gerontological nursing has its beginnings more than 50 years ago, specifically in the mid-1970s, in line with the worldwide movement to recognize the complexity of population aging and its challenges in the social, cultural, political and public health spheres. Since then, scientific production in this field has been related to the expansion of Stricto Sensu Graduate Programs, national legislation and international guidelines, denoting its growth and scientific maturity.Following this trend, important scientific communication vehicles have published the knowledge produced about gerontological nursing in the country. Among them, a bibliometric study on scientific production about older adults in the Revista Brasileira de Enfermagem (REBEn -Brazilian Journal of Nursing) identified, between 2000 and 2006, the predominance of qualitative investigations, conducted in the hospital setting, highlighting the participation of Stricto Sensu Graduate Programs. It was also observed, in this time frame, the need to invest in research related to the nursing care process, from the perspective of health promotion and improvement of older adults' quality of life (1) .Worldwide, another bibliometric study, carried out from 1900 to 2020, in the Web of Science database, identified 4,923 articles on the subject of gerontological nursing. The United States was the country with the highest scientific production (37.8%), followed by Canada (6.2%) and Australia (5.9%). In this ranking, Brazil occupied the tenth position (3.2%), being the first in Latin America. The most frequent themes were depression, malnutrition, education, Alzheimer's disease and other dementias. Trends in more current research topics were also observed, such as COVID-19, locomotor syndrome, interprofessional practice, emergency nursing and public health (2) . Still, in relation to this worldwide survey, an exponential growth in the number of publications was identified from 1990, with a maximum peak in 2018. The researchers compared the citation indicators of these articles with other bibliometric studies and found that scientific production in the area has been considered of interest to readers, however the citation rate has decreased in the last ten years (2) .Thus, when we observe the bibliometric indicators, the current production evidences the advance of scientific knowledge in gerontological nursing in recent decades. However, it is worth reflecting on the quality of the methodological approaches of the research produced in this field and, in the same way, if the themes are aligned with older adults' health needs, nursing practices and professional training. Based on these reflections, we highlight two international documents that contribute to this discussion.The Pan American Health Organization conducted a study to define nursing research priorities for the Regions of the Americas, guided by the concepts of universal access to health and universal health coverage. As a result of this work, six categories were listed, namely:...
