Oximetry at admission as a predictor of tomographic and functional impairment after 3-6 months in hospitalized patients with COVID-19.

OBJECTIVE: To investigate characteristics that may be associated with radiologic and functional findings following discharge in patients with severe coronavirus disease 2019 (COVID-19). METHODS: This single-center, prospective, observational cohort study comprised patients aged >18 years who were hospitalized with COVID-19 pneumonia, between May and October 2020. After 3 to 6 months of discharge, patients were clinically evaluated and underwent spirometry, a 6-minute walk test (6MWT), and chest computed tomography (CT). Statistical analysis was performed using association and correlation tests. RESULTS: A total of 134 patients were included (25/114 [22%] were admitted with severe hypoxemia). On the follow-up chest CT, 29/92 (32%) had no abnormalities, regardless of the severity of the initial involvement, and the mean 6MWT distance was 447 m. Patients with desaturation on admission had an increased risk of remaining CT abnormalities: patients with SpO2 between 88 and 92% had a 4.0-fold risk, and those with SpO2 < 88% had a 6.2-fold risk. The group with SpO2 < 88% also walked shorter distances than patients with SpO2 between 88 and 92%. CONCLUSION: Initial hypoxemia was found to be a good predictor of persistent radiological abnormalities in follow-up and was associated with low performance in 6MWT.

Escolaridade e conhecimento sobre duração recomendada para o aleitamento materno exclusivo entre gestantes na Estratégia de Saúde da Família / Education and knowledge about recommended duration of exclusive breastfeeding among pregnant women in the Family Health Strategy

Averiguar a proporção de gestantes acompanhadas em unidades de Saúde da Família que conhecem a duração ideal recomendada para o aleitamento materno exclusivo e identificar fatores associados ao conhecimento. Estudo transversal realizado em onze unidades de Saúde da Família em município do sul do país. Aplicou-se questionário estruturado e aferiu-se o conhecimento por meio de questão direta. Das 211 gestantes entrevistadas, 71,56% responderam corretamente à questão, sendo o maior índice de acerto entre as de maior escolaridade (p=0,013). Não se identificou associação entre o conhecimento correto e as características sócio-demográficas ou as relativas à saúde reprodutiva e assistência à saúde. Conclui-se que a proporção de gestantes acompanhadas em unidades de Saúde da Família com conhecimento sobre a duração recomendada para o aleitamento materno exclusivo foi baixa, por se tratar de uma informação básica, bastante abordada por profissionais de saúde e divulgada pela mídia. Autores chamam a atenção para a necessidade das equipes multidisciplinares de Saúde da Família intensificarem o trabalho de educação em saúde junto às gestantes com relação à prática do aleitamento materno, especialmente entre as gestantes de baixa escolaridade.

To verify the proportion of pregnant women followed at Family Health units who know the ideal recommended duration of exclusive breastfeeding and identify associated factors. Cross sectional study undertaken in eleven Family Health units at a municipality in the south of the country. A structured questionnaire was applied to evaluate pregnant women´s knowledge through a direct question. Among the 211 pregnant women interviewed, 71,56% answered correctly the question, with the highest index among those of higher education level (p= 0,013). We did not identify association between correct knowledge and women´s sociodemographic characteristics, reproductive health or health provision. We conclude that the proportion of pregnant women followed in Family Health units with adequate knowledge on the ideal recommended duration of exclusive breastfeeding was low, since it´s a basic information constantly approached by healthcare professionals and exposed in the media. Authors call the attention to the importance of multidisciplinary teams to intensify the education work in relation to breastfeeding, especially among those pregnant women with a low education level.
