OBJETIVO: Realizar uma revisão narrativa da literatura sobre os eixos norteadores e as implicações da Estratégia Saúde da Família na saúde pública do Brasil esclarecendo até que ponto o programa reduziu as desigualdades no acesso aos cuidados de saúde no país. MATERIAIS E MÉTODOS: Trata-se de uma revisão narrativa baseada na coleta de dados por meio de levantamento bibliográfico. A busca foi realizada nas bases de dados LILACS e MEDLINE, utilizando os descritores: Atenção Primária à Saúde / Primary Health Care / Atención Primaria de Salud, Estratégia Saúde da Família / Family Health Strategy / Estrategia de Salud de la Familia, Saúde Pública / Public Health / Salud Pública. RESULTADOS E DISCUSSÃO: Dentre os achados na literatura a respeito das implicações da Estratégia Saúde da Família na saúde pública do Brasil, destacaram-se aspectos a respeito do aumento na disponibilidade e acesso aos serviços de saúde, influenciando em melhores indicadores de saúde, como redução da mortalidade infantil, hospitalização evitável, mortalidade por doenças cerebrovasculares e cardiovasculares, maior equidade, mais acesso e continuidade do cuidado. CONSIDERAÇÕES FINAIS: As implicações positivas do programa quanto ao acesso da comunidade à rede de saúde resultaram na redução significativa das desigualdades nacionais referentes ao acesso à saúde.

Arboviruses, such as yellow fever virus (YFV), dengue virus (DENV), and chikungunya virus (CHIKV), present wide global dissemination and a pathogenic profile developed in infected individuals, from non-specific clinical conditions to severe forms, characterised by the promotion of significant lesions in different organs of the harbourer, culminating in multiple organ dysfunction. An analytical cross-sectional study was carried out via the histopathological analysis of 70 samples of liver patients, collected between 2000 and 2017, with confirmed laboratory diagnoses, who died due to infection and complications due to yellow fever (YF), dengue fever (DF), and chikungunya fever (CF), to characterise, quantify, and compare the patterns of histopathological alterations in the liver between the samples. Of the histopathological findings in the human liver samples, there was a significant difference between the control and infection groups, with a predominance of alterations in the midzonal area of the three cases analysed. Hepatic involvement in cases of YF showed a greater intensity of histopathological changes. Among the alterations evaluated, cell swelling, microvesicular steatosis, and apoptosis were classified according to the degree of tissue damage from severe to very severe. Pathological abnormalities associated with YFV, DENV, and CHIKV infections showed a predominance of changes in the midzonal area. We also noted that, among the arboviruses studied, liver involvement in cases of YFV infection was more intense.

Objective: This study aims to gather, characterize, evaluate and integrate studies that investigated the management of nursing care in the main clinical emergencies. Method: This is a review of national and international literature, which includes the analysis of research results that offer support to nurses in relation to conduct in the main clinical emergencies. Results: Among the most cited clinical emergencies in the articles, the management of nursing care in hypertensive crisis, hyperglycemic crisis, upper and lower gastrointestinal bleeding, acute pulmonary edema, burn patients and sepsis stand out. Final considerations: The study had limitations regarding the number of scientific articles specifically related to urgency and nursing care. Furthermore, it is concluded that nurses play a fundamental role in the prevention, diagnosis, treatment, evolution and stabilization of the clinical picture.

Objectives: To know the ethical parameters in relation to the allocation of scarce resources in the midst of the pandemic. Method: This is an integrative literature review that included articles published in 2020, during the Covid-19 pandemic, in journals indexed in Lilacs and Scielo databases, available for free, and studies discussed in international bioethics forums focused on discussing ethical dilemmas during the pandemic. Results: There are strong justifications for the development and application of triage protocols in case the pandemic exceeds the capacity to provide intensive care to all patients. Conclusion: It is important that hospitals take immediate steps to develop a decision-making process, anticipate what will be the priority criteria in this pandemic moment and involve the ethics team in the institutions, in order to take the burden off the decision of health professionals, which are already overloaded.
