RESUMO Objetivo: Avaliar o conhecimento das mães acerca da exposição solar relacionada com níveis séricos de vitamina D no período neonatal. Métodos: Estudo observacional, analítico e transversal, realizado de agosto de 2020 a maio de 2021 por meio de questionário dirigido às mães de recém-nascidos, em uma maternidade no sul do Brasil. Resultados: De 141 entrevistadas, 132 (93,6%) acreditam ser importante expor o lactente ao sol no primeiro mês de vida, 101 (71,6%) acham que essa exposição aumenta os níveis de vitamina D, 86 (61,0%) receberam tal informação de um médico, 108 (76,6%) acreditam que expor o neonato ao sol não causa riscos para a saúde, 88 (62,4%) acham que não é necessário usar proteção contra radiação solar ao expor o neonato ao sol, e 96 (68,1%) afirmaram que apenas a exposição ao sol basta para manter os níveis adequados de vitamina D durante o período neonatal. Apenas duas mães (1,4%) afirmaram que não se deve expor o neonato ao sol e uma (0,7%) que a exposição solar pode causar problemas de pele. Conclusões: A maioria das mães não possui conhecimento satisfatório acerca da exposição solar relacionada aos níveis séricos de vitamina D no período neonatal. É notável a necessidade de informar e esclarecer a população sobre a exposição solar nesse período, além de disseminar a maneira adequada de manter os níveis séricos de vitamina D.

ABSTRACT Objective: To assess mothers’ knowledge on sun exposure related to serum vitamin D levels in the neonatal period. Methods: Observational, analytical and cross-sectional study, carried out from August 2020 to May 2021 through a questionnaire directed to mothers of newborns, in a maternity hospital in Southern Brazil. Results: From 141 interviewees, 132 (93.6%) believe it is important to expose the neonate to sun, 101 (71.6%) think this exposure can increase vitamin D levels, 86 (61%) received such information from a doctor, 108 (76.6%) believe there are no risks of sun exposure, 88 (62.4%) claim it isn´t necessary to use any kind of protection, 96 (68.1%) said that only exposure to the sun was necessary to maintain adequate levels of vitamin D during the neonatal period. Only two mothers (1.4%) claim that you should not exposure the neonate to the sun, and only one (0.7%) stated that sun expose can cause skin problems. Conclusions: Most mothers lack satisfactory knowledge about sun exposure related to serum vitamin D levels in the neonatal period. The need to inform and clarify the population about sun exposure during this period is remarkable, in addition to disseminating the proper way to maintain serum levels of vitamin D.

Abstract Background Congenital heart diseases (CHD) are one of the most prevalent malformations, and the screening tests to identify critical congenital heart disease (CCHD) is the pulse oximetry test, with subsequent investigation and treatment. Objective To quantify positive pulse oximetry tests and verify the prevalence of CCHD detected by it in asymptomatic newborns, ≥35 gestational weeks, in a Brazilian maternity hospital. Methodology This is an observational, retrospective, quantitative, analytical and cross-sectional study, conducted from October 2020 to May 2022, in a maternity hospital in southern Brazil, through the collection of records of positive oximetry pulse tests, following the norms of screening CCHD test of the Brazilian Society of Pediatrics (SBP), after they were evaluated with echocardiography for confirmation or exclusion of CHD. Results A total of 5,667 newborns were evaluated in this study, according to the inclusion criteria; 0.17% (n = 10) had a positive pulse oximetry test. Regarding the results of the echocardiography of the neonates with a positive test, two were normal, seven were cases of patent foramen ovale (PFO), and one was a case (0,017%) with interatrial communication (IAC) diagnosis. In the same period, five neonates with CCHD were born, symptomatic, diagnosed by physical examination, and referred to neonatal intensive care units (NICU) before taking the neonatal cardiac screening (< 24 hours of life). Conclusion The prevalence of positive pulse oximetry tests was 0.17% and none CCHD was detected. Five cases of CCHD were born in this period, but they were diagnosed before the recommend time to perform the screening test.
