Produção de redes sociais digitais como estratégia de educação em saúde no contexto da pandemia da COVID-19 / Production of digital social networks as a health education strategy in the context of the COVID-19 pandemic

Trata-se de um relato de experiência com o objetivo de elucidar o processo de produção de comunicação, por meio da rede social digital Instagram, a partir de cards informativos, como estratégia de educação em saúde no contexto da pandemia por fisioterapeutas do Núcleo Ampliado em Saúde da Família e Atenção Básica 1 (NASF-AB 1) residentes em Saúde da Família. A produção se deu por quatro blocos de publicações incluindo: exercícios na quarentena; mitos e verdades sobre a COVID-19; autocuidado e home office; desigualdade racial. Com a estratégia de cuidado adotada foi possível atingir alcance dos usuários adscritos ao território e extrapolar o espaço geográfico incluindo outros municípios por meio das contas profissionais funcionando como uma potente ferramenta de divulgação científica e consideramos importante a adoção de tecnologias de comunicação pelas redes sociais digitais nos serviços públicos de saúde para otimizar o diálogo e a interação com os usuários.

This is an experience report through the elucidation of the communication production process, through digital social network Instagram, as a health education strategy in the context of the pandemic by physiotherapists from the Extended Nucleus in Family Health and Primary Care 1 (NASF- AB 1) residents of Family Health. The production took place in four blocks of publications, including: physical exercises in the quarantine; myths and truths about COVID-19; self-care and home office; racial inequality. With the adopted care strategy, it was possible to reach the users assigned to the territory and to extrapolate the geographic space, including other municipalities through professional accounts, functioning as a powerful tool for scientific dissemination. In addition, we consider it important to adopt clarification technologies through digital social networks in public health services to optimize dialogue and interaction with users.

The entropy of RR intervals is associated to gestational age in full-term newborns with adequate weight for gestational age.

INTRODUCTION: The variability of successive RR intervals has been pointed out as an indicator of systemic homeostasis. The entropy of successive RR intervals is associated with a greater adaptive capacity, which is essential after childbirth, characterized by a change from an intrauterine environment that constantly adapts to the fetal demands, to an extrauterine environment that requires constant biological adaptations by the neonate. OBJECTIVES: To analyze the association between gestational age (GA) and the entropy of RR intervals in term infants with adequate birth weight in the first hours of extrauterine life. METHODS: In a cross-sectional study design maternal, labor and neonatal characteristics were collected from the obstetric records. Successive RR intervals were recorded from neonates up to 72 hours (i.e. 3 days) of birth. SUBJECTS: Fifty term infants, healthy and with adequate birth weight. Outcome measures: the variability of RR intervals was analyzed obtaining the entropy of 1000 successive RR intervals. Pearson's correlation was used to evaluate the association between GA and the entropy of successive RR intervals, while linear regression was used to obtain the coefficient of determination (r2) as well as a prediction model. The adequacy of the prediction model was evaluated using the Komolgorov-Smirnov test to evaluate the residuals distribution. RESULTS: There was a positive and significant association between the studied variables (r = 0.437; p = .002). The coefficient of determination allowed us to infer that approximately 19.3% of the RR interval entropy from the studied sample can be explained by the GA (r2 = 0.193; p = .002). The analysis of the residuals distribution confirmed that the regression model obtained here was adequate. CONCLUSION: Our results indicate that, even within a normal range of GA (≥37 a < 42 weeks) and birth weight, a longer intrauterine life allows a greater entropy of successive RR intervals, indicating a greater maturation of biological systems and adaptive capacity.

Sarcopenia is associated to an impaired autonomic heart rate modulation in community-dwelling old adults.

PURPOSE: The aims of this study were to compare the autonomic heart control parameters from sarcopenic and non-sarcopenic community-dwelling elders. METHODS: This is a cross-sectional study including 76 community-dwelling old adults, which was clinically stratified as sarcopenic or non-sarcopenic, according to the current recommendations. They were submitted to 5-min recordings of successive RR intervals. The analysis of the RR intervals variability was carried out in time (mean RR, RMSSD, pNN50, SDNN and triangular index) and frequency domains (LFnu, HFnu and LF/HF ratio), and with nonlinear methods (SD1, SD2, and D2). The parameters of autonomic heart rate modulation (AHRM) were adjusted for potential confounders: sex, diabetes, beta-blockers use, cardiovascular disease, body mass index and physical activity level, smoking habit. Normality of the data was tested by Kolmogorov-Smirnov test and, since most variables did not exhibit a normal distribution the Mann-Whitney test was used to compare the parameters of AHRM. The significance level was set as p ≤ 0.05 and all statistical procedures were performed with SPSS®. RESULTS: Adjusted parameters of AHRM obtained from time domain and nonlinear methods were significantly different between sarcopenic and non-sarcopenic elders (p < 0.05), while parameters obtained from frequency domain analysis did not were different between groups (p > 0.05). CONCLUSION: Sarcopenic old adults exhibited lower parasympathetic-associated modulation, suggesting a poor cardioprotection associated to this condition.
