This paper presents the Mechanical Ventilator Milano (MVM), a novel intensive therapy mechanical ventilator designed for rapid, large-scale, low-cost production for the COVID-19 pandemic. Free of moving mechanical parts and requiring only a source of compressed oxygen and medical air to operate, the MVM is designed to support the long-term invasive ventilation often required for COVID-19 patients and operates in pressure-regulated ventilation modes, which minimize the risk of furthering lung trauma. The MVM was extensively tested against ISO standards in the laboratory using a breathing simulator, with good agreement between input and measured breathing parameters and performing correctly in response to fault conditions and stability tests. The MVM has obtained Emergency Use Authorization by U.S. Food and Drug Administration (FDA) for use in healthcare settings during the COVID-19 pandemic and Health Canada Medical Device Authorization for Importation or Sale, under Interim Order for Use in Relation to COVID-19. Following these certifications, mass production is ongoing and distribution is under way in several countries. The MVM was designed, tested, prepared for certification, and mass produced in the space of a few months by a unique collaboration of respiratory healthcare professionals and experimental physicists, working with industrial partners, and is an excellent ventilator candidate for this pandemic anywhere in the world.

Objective: to analyze, in the scientific literature, the knowledge available on the use of the prone position in pregnant women diagnosed with COVID-19 or other health conditions. Method: an integrative literature review developed through the following guiding question: What is the scientific knowledge available on the use of the prone position in pregnant women with COVID-19 or other health conditions? The search for studies was carried out in eight databases. Results: using the prone position in pregnant women with Acute Respiratory Distress syndrome allowed for improvements in lung compliance and oxygenation. It also allowed reducing uterine compression on the maternal large vessels, and a reduction in blood pressure was observed in pregnant women with pre-eclampsia. The prone position was also safe in the surgical management of pregnant patients. In addition, the following conditions stood out as disadvantages related to the prone position in pregnant women: possibility of aortocaval compression, causing severe hypotension, and inability to easily monitor fetal status or to perform emergency Cesarean sections. Conclusion: the prone position was considered safe, reliable and comfortable for its use in the clinical management of pregnant women, where specific care measures must be taken to avoid compression of gravid abdomen, as well as fetal monitoring is important to detect placental circulation impairment.

Objective: to unveil the experience of the elderly with social isolation in the pandemic of COVID-19. Methods: qualitative study, with 14 elderlies in social isolation. The content was recorded and processed using the software Interface de R pour les Analyses Multidimensionnelles de Textes et de Questionnaires. Results: six classes were obtained, the first focused on spirituality and pre-pandemic pleasurable activities; the second was related to missing the extra-household routine and family life; the third, to the construction of a new routine; the fourth, to the strategies adopted for the prevention of COVID-19; the fifth, to the signs/symptoms experienced during the infection; and the sixth class, to the fear of dying. Conclusion: the experience of the elderly was permeated by the adaptation of routine, adoption of preventive measures and feelings of anguish in the face of uncertainties.

Objectives: to create and validate a serial album for Pressure Ulcer prevention in the hospital environment. Methods: a methodological study with the production of the serial album and validation by 22 judges and 22 patients. The content was based on the integrative review and the reports of the World Health Organization. It was considered a Content Validity Index equal to or greater than 80% in the items and the binomial test for the judges’ agreement. Results: the serial album entitled “Pressure Ulcer Prevention in the hospital environment” has 13 pages. In the content and layout validation, all items had an agreement above 80% among the participants. The overall Content Validity Index was 0.99 for the judges and 1.0 for the patients. Conclusions: the constructed and validated material presented itself as an adequate instrument to be used in health education activities.

Objetivo: avaliar o impacto da Febre Chikungunya nas atividades de vida diária (AVDs) de pessoas idosas. Método: estudo exploratório realizado em 2019, em Redenção-CE/Brasil, com 248 idosos acompanhados por Centros de Saúde da Família. Os dados foram coletados com instrumento estruturado que continha variáveis demográficas, clínicas e com a Escala de Katz. A análise dos dados ocorreu a partir do teste qui-quadrado de Pearson. Resultados: houve predomínio de idosos do sexo feminino (73,79%) com média de idade de 71 anos e baixo grau de escolaridade (85,48%). Verificou-se associação estatisticamente significante entre disfunções de cunho articular e limitação para AVDs. A principal atividade básica desempenhada com limitações foi transferir-se (63,9%) e 23,7% dos idosos foram considerados parcialmente dependente e 53,8% totalmente dependentes nas atividades básicas. Todas as atividades instrumentais eram realizadas com limitações. Conclusão: constatou-se que a infecção pela Febre Chikungunya impactou negativamente a funcionalidade dos idosos. Assim, o planejamento do cuidado de enfermagem precisa ser pautado em práticas que atenuem os efeitos das sequelas da doença na qualidade de vida desses pacientes.

Objective To evaluate the effectiveness of the Arco de Maguerez in teaching nursing students about the Bladder Catheter. Method Quasi-experimental study conducted at a public university in northeastern Brazil, with 29 students, in a single group, in the period of october 2018. Data were collected before and after using the Arco de Maguerez in educational intervention, using validated instruments, referring to knowledge and practice. IBM SPSS Statistics software version 24 was used for statistical analysis. The level of significance was set at 5% and the 95% confidence interval. Data analysis was performed using the McNemar and Mann-Whitney test. Results The median of correct answers for knowledge was 7, in the pre-test, and 9 in the post-test (p> 0.001). Regarding practice, in the pre-test the median of correct answers was 28 and, in the post-test, it went to 36, p> 0.001. The academics explained that the AM technology based on the problematization of a fictitious clinical case made learning about Bladder Catheterization Delay clear and feasible. Conclusion The Arco de Maguerez was effective in improving the knowledge and skill of nursing students regarding the Bladder Catheter.

Este estudo tem o objetivo de analisar conhecimento e prática de acadêmicos de enfermagem acerca da punção venosa periférica antes e depois da aplicação do Team-Based Learning (TBL). Trata-se de estudo do tipo antes e depois, quantitativo, realizado com estudantes de enfermagem em universidade na zona norte do estado do Ceará. A coleta de dados foi realizada em quatro etapas: pré-teste teórico, pré-teste prático, TBL, pós-teste prático. Foi aplicado teste de McNemar e Wilcoxon para comparar os acertos nos testes teóricos e práticas antes e após a intervenção educativa. No pré-teste teórico houve média de acertos de 24,43 (DP±1,79), enquanto no pós-teste a média de acertos foi de 25,93 (DP±1,33). No tocante ao conhecimento, no pré-teste houve média de acertos de 24,43 (DP±1,79), enquanto no pós-teste a média de acertos foi de 25,93 (DP±1,33). Assim, observou-se significância no aumento da mediana de acertos teóricos (p=0,008). Em relação à prática, a média de acertos foi de 11,68 (DP±3,94) no pré-teste e 20,18 (DP±3,0) no pós-teste (p=0,000). O uso do TBL para o ensino do conteúdo teórico da PVP foi efetivo, tendo em vista que houve aumento na média de acertos das questões no pós-teste. Sugere-se a realização de novos estudos que objetivem utilizar outras metodologias para o ensino de procedimentos de enfermagem.
