Purpose: to identify the knowledge of community health workers on practices and promotion of breastfeeding. Methods: this is a cross-sectional descriptive study aimed to investigate a sample of 148 health workers quantitatively and qualitatively. Data collection was performed by applying a semi-structured questionnaire with open and closed questions. The following variables were analysed: sociodemographic data, capacity to provide breastfeeding guidance, participation in training and courses, and knowledge of the breastfeeding benefits for mother and baby. Statistical analysis was performed with chi-square test, exact Fisher's test and G-test at significance level of 5%. Open questions were analysed according to the qualitative research technique.Results: approximately, 45.95% of the health workers were not trained to provide nursing mothers with practical guidance on breastfeeding, and 63.30% never attended courses on breastfeeding. The majority of health workers mentioned breastfeeding benefits only for the baby, namely: nutrition, immunology, development, health, dentition, and bones. There was a statistically significant association between the capacity to provide breastfeeding guidance and participation in training (p<0.001). Conclusion: the health workers had not participated in training courses to follow up nursing mothers, in addition to having a limited knowledge on practices and promotion of breastfeeding and paying late postnatal home visits.

Introduction: Occupational exposure is a major risk factor for hepatitis B (HB) transmission. Methods: Vaccination coverage and immunity verification from 64 dentists of the Brazilian Unified Health System were investigated. An immunochromatographic method was used to verify immunity against the disease. Results: Overall, 77.77% of participating dentists completed the vaccination schedule; 37.50% had negative anti-HBs test results. Furthermore, 60.93% of participants never underwent anti-HBs tests and 40% did not know how to correctly interpret results. Conclusions: Numerous dentists were not immune to the disease. Few participants previously performed the test, with many not knowing how to interpret the results.

Objective: to investigate dental auxiliaries (DA) hepatitis B immunization in Brazilian National Health System (SUS) services in nine cities in São Paulo State, Brazil, in 2018. Methods: this was a cross-sectional study based on interviews using a questionnaire as well as evaluation of immunity using the anti-HBs test, evaluation of prior testing, test result and interpretation and guidance provided about hepatitis B. Results: of the 70 registered DA, 35 completed the course of vaccinations, 29 had negative anti-HBs test results, 16 had tested previously, and 43 did not correctly understand their result; there was association (p=0.025) between completed course of vaccinations and receipt of guidance. Conclusion: most DA received guidance about hepatitis B; however, a considerable portion did not complete the course of vaccinations and had negative anti-HBs test results; few DA had tested previously nor correctly interpreted the result; evidence was found of an alarming scenario in which there are severe shortcomings in DA hepatitis B immunization.

O crescimento da população mundial tem aumentado a demanda por alimentos e exigido a produção alimentícia em grande escala através do emprego de inúmeras práticas agrícolas, como o uso de agrotóxicos na lavoura visando eliminar pragas e garantir a produtividade. Entretanto, as consequências do uso desses produtos e suas repercussões à saúde humana tem sido alvo de discussão no meio acadêmico. Objetivo: identificar os impactos dos agrotóxicos à saúde mental. Metodologia: trata-se de um estudo com abordagem descritivo-analítico-reflexiva. Foram selecionados estudos publicados entre os anos de 2011 e 2020, selecionados através dos bancos de dados: National Library of Medicine (PubMed), Biblioteca Virtual em Saúde (BVS) e Scientific Electronic Library (SciELO). Foram empregados os descritores em língua inglesa e português: Agrotóxico OR Agrochemicals AND Depressão OR Depression AND “Água Potável” OR “Drinking Water” AND/OR Alimentos OR Food. Critérios de inclusão: artigos científicos com Qualis Capes em Saúde Coletiva acima de B3; trabalhos de conclusão de curso a nível de mestrado e doutorado. Resultados: Foram selecionados onze estudos que apontaram uma relação de causa-efeito entre a exposição humana aos agrotóxicos e os prejuízos à saúde mental, como: depressão, declínio cognitivo, ansiedade, fadiga, desequilíbrio emocional. Conclusão: Estudos apontam que o uso de defensivos agrícolas tem afetado a saúde humana. Evidencia-se a importância da conscientização do uso de Equipamento de Proteção Individual (EPI) e descarte correto das embalagens destes produtos. Sugere-se o desenvolvimento de pesquisas que apontem estratégias agrícolas mais sustentáveis em substituição aos pesticidas químicos, como o uso de biopesticidas.
