Real-Lab-Day: undergraduate scientific hands-on activity as an authentic learning opportunity in microbiology education.

Traditional lab classes in microbiology are common in several educational institutions, which can provide a learning experience disconnected from the myriad of experiments performed in research laboratories. Attempting to promote an authentic learning opportunity of the functioning of a bacteriology research laboratory, we developed the "Real-Lab-Day," a multimodal learning experience to develop competencies, abilities, critical analysis, and teamwork skills for undergraduate students. Students were divided into groups and assigned to research laboratories to be mentored by graduate students, to design and carry out scientific assays. Undergraduate students were introduced to methods such as cellular and molecular assays, flow cytometry, and fluorescence microscopy, as tools to address scientific questions about bacterial pathogenicity, bacterial resistance, and other topics. To consolidate their learning, students created and presented a poster in a rotational panel of peer learning. The perceived learning and interest in microbiology research were improved by the Real-Lab-Day experience, and >95% of the students approved the Real-Lab-Day as a teaching tool in microbiology. Students exposed to a research laboratory had a positive experience with the teaching method, and over 90% saw it as beneficial to improve their understanding of the scientific concepts discussed during lectures. Likewise, their interest in pursuing a career in microbiology was stimulated by the Real-Lab-Day experience. In conclusion, this educational initiative depicts an alternative methodology to connect students to the research and offers an opportunity to be in close contact with experts and graduate students, who gain teaching experience.

Adopt a Bacterium - an active and collaborative learning experience in microbiology based on social media

ABSTRACT The "Adopt a Bacterium" project is based on the use of social network as a tool in Microbiology undergraduate education, improving student learning and encouraging students to participate in collaborative learning. The approach involves active participation of both students and teachers, emphasizing knowledge exchange, based on widely used social media. Students were organized in groups and asked to adopt a specific bacterial genus and, subsequently, submit posts about "adopted genus". The formative assessment is based on posting information on Facebook®, and the summative assessment involves presentation of seminars about the adopted theme. To evaluate the project, students filled out three anonymous and voluntary surveys. Most of the students enjoyed the activities and positively evaluated the experience. A large amount of students declared a change in their attitude towards the way they processed information, especially regarding the use of scientific sources. Finally, we evaluated knowledge retention six months after the end of the course and students were able to recall relevant Microbiology concepts. Our results suggest that the "Adopt a Bacterium" project represents a useful strategy in Microbiology learning and may be applied to other academic fields.

Adverse events of vaccines and the consequences of non-vaccination: a critical review.

OBJECTIVE: To analyze the risks related to vaccines and the impacts of non-vaccination on the world population. METHODS: This is a narrative review that has considered information present in the bibliographic databases NCBI-PubMed, Medline, Lilacs, and Scientific Electronic Library Online (SciELO), between November 2015 and November 2016. For the analysis of outbreaks caused by non-vaccination, we considered the work published between 2010 and 2016. RESULTS: We have described the main components of the vaccines offered by the Brazilian public health system and the adverse events associated with these elements. Except for local inflammatory reactions and rare events, such as exacerbation of autoimmune diseases and allergies, no causal relationship has been demonstrated between the administration of vaccines and autism, Alzheimer's disease, or narcolepsy. On the other hand, the lack of information and the dissemination of non-scientific information have contributed to the reemergence of infectious diseases in several countries in the world and they jeopardize global plans for the eradication of these diseases. CONCLUSIONS: The population should be well informed about the benefits of vaccination and health professionals should assume the role of disseminating truthful information with scientific support on the subject, as an ethical and professional commitment to society.

RESUMO OBJETIVO: Analisar os riscos relacionados às vacinas e os impactos da não vacinação para a população mundial. MÉTODOS: Revisão narrativa que considerou informações contidas nas bases de dados bibliográficos NCBI-PubMed, Medline, Lilacs e Scientific Electronic Library Online (SciELO), no período compreendido entre novembro de 2015 e novembro de 2016. Para a análise de surtos ocasionados pela não vacinação foram considerados os trabalhos publicados entre 2010 e 2016. RESULTADOS: Foram descritos os principais componentes das vacinas oferecidas pelo sistema público de saúde brasileiro e eventos adversos associados a esses elementos. Com exceção de reações inflamatórias locais e efeitos raros como exacerbação de doenças autoimunes e alergias, não foi demonstrada relação causal entre a administração de vacinas e autismo, mal de Alzheimer ou narcolepsia. Por outro lado, a falta de informações e a divulgação de informações não científicas têm contribuído para a reemergência de doenças infecciosas em diversos países no mundo e põe em risco planos globais para a erradicação de doenças infecciosas. CONCLUSÕES: A população deve estar bem informada quanto aos benefícios da vacinação e os profissionais da saúde devem assumir o papel de divulgar informações verídicas e com respaldo científico sobre o tema, como compromisso ético e profissional junto à sociedade.
