This integrative review aimed to identify and assess evidence available about the use of high-efficiency air filters, protective isolation and masks for infection prevention in patients submitted to hematopoietic stem cell transplantation during hospitalization. LILACS, PUBMED, CINAHL, EMBASE and the Cochrane Library were used to select the articles. Of the 1023 identified publications, 15 were sampled. The use of HEPA filters is recommended for patients submitted to allogeneic transplantation during the neutropenia period. The level of evidence of protective isolation is weak (VI) and the studies evaluated did not recommend its use. No studies with strong evidence (I and II) were evaluated that justify the use of masks, while Centers for Disease Control and Prevention recommendations should be followed regarding the use of special respirators by immunocompromised patients. The evidenced data can support decision making with a view to nursing care.

From the perspective of Collective Health, this study aimed to analyze how the teaching of health education in undergraduate Nursing courses is processed contemporarily. The Educational Institutions were selected so as to represent the public and private sectors. The subjects, teachers responsible for developing the theme, were identified from the indications of the Coordinators of the Courses. An exploratory, descriptive, analytical, study with a qualitative approach was developed, which utilized documental analysis and a semi-structured interview based on a script, the analysis of which followed the steps of content analysis and identification of thematic nuclei. The results showed that the teaching developed remains largely linked with the biomedical preventive model and that the concepts of critical education and ?popular? educational practices are scarce, due to the deficient political education of the teachers, and more broadly, as a consequence of coping with an academic context of the implementation of the neoliberal ideas.
