Abstract Objective: This study aimed to evaluate the Neuropsychomotor Development (NPMD) of newborns exposed to SARS-CoV-2 in the perinatal period using the Bayley III scale at 6 months of age. Methods: Childcare appointments were scheduled for the included newborns in the study. During the 6-month consultation, the Screening Test for Bayley III Scale and, based on it, children were classified as “low risk”, “moderate risk” or “high risk” in the domains: of cognitive, receptive language, expressive language, fine motor, and gross motor. Those classified as “moderate risk”; or “high risk” received guidance about NPMD stimuli and were instructed to maintain follow-up. Results: Only 13 (37.1 %) of the newborns were classified as low risk in receptive language and 18 (51.4 %) in gross motor skills, with the domains most affected. Prematurity was a risk for cognitive incompetence (moderate risk/high-risk classification) (coefficient: 1.89, Odds Ratio = 6.7, 95 % CI 1.3‒35, p = 0.02). Lower birth weight that 2.500g had a similar effect on cognitive incompetence (coefficient: 1.9, Odds Ratio = 6.2, 95 % CI 1.2‒32.2, p = 0.02). Exclusive breastfeeding at hospital discharge (n = 8) was protective for incompetence (high risk/moderate risk) in the language domain (coefficient -2.14, OR = 0.12, 95 % CI 0.02‒0.71, p = 0.02). Conclusions: The children included in the study must be monitored and their development monitored in order to clarify whether there is a relationship between the delay in NPMD and perinatal exposure to COVID-19, as delays were observed in these preliminary results.

Resumo Fundamento O período neonatal é marcado por muitas alterações importantes no sistema cardiovascular, principalmente na primeira semana de vida. Diferentemente da população adulta, estudos sobre dados de eletrocardiograma (ECG) no período neonatal são escassos. Este é o primeiro estudo a descrever alterações eletrocardiográficas em uma coorte de recém-nascidos com ecocardiogramas normais. Objetivos Analisar padrões eletrocardiográficos de uma população de recém-nascidos a termo, sem anomalias morfológicas ou funcionais cardíacas, e comparar os resultados com a literatura. Métodos Neste estudo observacional, ecocardiogramas e resultados de ECG de 94 neonatos divididos em três grupos etários (até 24 horas, entre 25 e 72 horas, e entre 73 e 168 horas de vida) foram avaliados e comparados com aqueles descritos por Davignon et al. Um valor de p < 0,05 foi considerado estatisticamente significativo. Resultados Diferenças significativas na direção da onda T foram detectadas nas derivações V1 (p= 0,04), V2 (p= 0,02), V3 (p= 0,008) e V4 (p= 0,005). Houve diferenças entre nossos resultados e a literatura atual na maioria dos parâmetros. Conclusão Recém-nascidos a termo com menos de 24 horas de vida apresentaram significativamente mais ondas T positivas que aqueles com mais horas de vida. Encontramos muitas diferenças nos parâmetros de ECG em comparação aos descritos por Davignon et al., particularmente nas amplitudes de P, Q, R, S, duração do QRS, R/S e R+S. Esses achados indicam a necessidade de mais estudos para uma interpretação definitiva do ECG em recém-nascidos.

Abstract Background The neonatal period is marked by major changes in the cardiovascular system, especially in the first week of life. Unlike the adult population, studies on electrocardiogram (ECG) data in the neonatal period are scarce. This is the first study to describe electrocardiographic changes in a cohort of newborns with normal echocardiograms. Objectives To analyze the electrocardiographic patterns of a population of full-term NB, without any cardiac morphological or functional anomalies, and compare the results with the literature. Methods In this observational study, echocardiograms and ECG results from 94 newborns divided in three age groups (up to 24 hours, between 25 and 72 hours, and between 73 and 168 hours of life) were evaluated and compared with those reported by Davignon et al. A p-value <0.05 was considered statistically significant. Results There were significant differences in T-wave direction in leads V1 (p= 0.04), V2 (p= 0.02), V3 (p= 0.008) and V4 (p= 0.005) between the three age groups. There were differences between our findings and the current literature in most of the parameters. Conclusion Term newborns within 24 hours of life showed significantly more positive T waves than older ones. Many differences from the Davignon’s ECG parameters were found, particularly in the P, Q, R, S amplitudes, QRS duration, R/S and R+S. These findings indicate that more studies are needed for a definitive interpretation of the ECG in newborns.

Abstract Introduction Limited data are available on pregnant women with COVID-19 and their neonates. Objective This study aimed to describe clinical characteristics and evolution from birth to discharge of a retrospective cohort of 71 neonates, with one set of twins, born to women with COVID-19 diagnosed at the end of pregnancy. The authors included all newborns admitted into a neonatal unit of a tertiary hospital in Brazil, between March 2020 and March 2021, whose unvaccinated mothers had COVID-19 symptoms and RT-PCR (Real-Time Polymerase Chain Reaction) for SARS-CoV-2 positive within fourteen days prior to delivery. Newborns to mothers with COVID-19 symptoms and negative tests for SARS-CoV-2 were excluded. Results The main route of birth delivery was cesarean, corresponding to 60 pregnant women (84.5%). The foremost indications for cesarean were pregnant with critical disease (24.6%) and acute fetal distress (20.3%). The mean birth weight was 2452 g (865‒3870 g) and the mean gestational age was 345/7weeks (25‒40 weeks). There were 45 premature newborns (63.3%), of which 21 newborns (29.5%) were less than 32 weeks of gestational age. RT-PCR for SARS-CoV-2 on oropharyngeal swabs was positive in 2 newborns (2.8%) and negative in the other 69 newborns (97.2%). Most newborns (51.4%) needed respiratory support. Therapeutic interventions during hospitalization were inotropic drugs (9.9%), antibiotics (22.8%), parenteral nutrition (26.8%), and phototherapy (46.5%).

RESUMO

SUMMARY On 11th March 2020, the World Health Organization (WHO) declared the COVID-19 a pandemic. The Obstetrics and Neonatology disciplines needed to be revised to suit the institutional need to expand intensive care beds to care for confirmed or suspected patients with COVID-19 in the state of São Paulo, following the recommendations of the Institutional Crisis Committee. Three different actions were needed: the structuring of teams and advanced medical post to attend COVID-19-free patients and those with suspect or confirmed COVID-19; elaborating the protocols from the delivery room throughout hospitalization. Some special considerations about breastfeeding and rooming-in were needed. The third action was the drafting of a protocol to admit infants from other hospitals with confirmed COVID-19 as the unit never admitted outpatients before.

RESUMO OBJETIVO Estas recomendações têm como objetivo orientar o aleitamento materno de mães com Covid-19 suspeita ou confirmada. MÉTODO Foi realizada revisão da literatura médica recente sobre aleitamento materno de mães com Covid-19 suspeita ou confirmada, focando o período neonatal. RESULTADOS Foram analisadas 20 publicações recentes sobre aleitamento materno, Covid-19 e sua transmissão pelo leite. Foram apresentadas as possíveis opções maternas em relação ao aleitamento e suas consequências para o binômio mãe-filho. CONCLUSÃO Todas as opções maternas em relação à amamentação são justificáveis, porque a infecção por Covid-19 ainda é pouco conhecida. Porém, as puérperas e seus familiares devem ser muito bem orientados, realizando uma opção consciente e baseada nas informações disponíveis na literatura até o momento.

SUMMARY OBJECTIVE These recommendations aim to provide guidance on breastfeeding for mothers with suspected or confirmed Covid-19. METHODS We performed a review of the recent medical literature on breastfeeding mothers with suspected or confirmed Covid-19, focusing on the neonatal period. RESULTS We analyzed 20 recent publications on breastfeeding, Covid-19, and its transmission through breastmilk. We presented possible options for breastfeeding and their consequences for the mother and the child. CONCLUSION All maternal decisions in relation to breastfeeding are justifiable since the infection by Covid-19 is still poorly known. However, puerperal women and their families must be very well informed to make a conscious choice based on the information available in the literature so far.

This article presents expert recommendations for assisting newborn children of mothers with suspected or diagnosed coronavirus disease 2019 </mac_aq>(COVID-19). The consensus was developed by five experts with an average of 20 years of experience in neonatal intensive care working at a reference university hospital in Brazil for the care of pregnant women and newborns with suspected or confirmed COVID-19. Despite the lack of scientific evidence regarding the potential for viral transmission to their fetus in pregnant mothers diagnosed with or suspected of COVID-19, it is important to elaborate the lines of care by specialists from hospitals caring for suspected and confirmed COVID-19 cases to guide multidisciplinary teams and families diagnosed with the disease or involved in the care of pregnant women and newborns in this context. Multidisciplinary teams must be attentive to the signs and symptoms of COVID-19 so that decision-making is oriented and assertive for the management of the mother and newborn in both the hospital setting and at hospital discharge.

RESUMO Objetivo: Avaliar as repercussões da hiperinsuflação manual, realizada com ressuscitador manual com e sem válvula de pressão positiva expiratória final, sobre a função respiratória de recém-nascidos pré-termo em ventilação mecânica. Métodos: Estudo transversal com recém-nascidos pré-termo com idade gestacional inferior a 32 semanas, em ventilação mecânica e dependentes desta aos 28 dias de vida, estáveis hemodinamicamente. A hiperinsuflação manual foi aplicada de forma randomizada, alternando o uso ou não uso da válvula de pressão positiva expiratória final, seguida de aspiração intratraqueal finalizando a manobra. Para os dados nominais, foi aplicado o teste de Wilcoxon com hipótese bilateral ao nível de significância de 5% e poder de teste de 80%. Resultados: Foram estudados 28 recém-nascidos pré-termo com peso médio de nascimento 1.005,71 ± 372.16g, idade gestacional média 28,90 ± 1,79 semanas, idade corrigida média de 33,26 ± 1,78 semanas, tempo médio de ventilação mecânica de 29,5 (15 - 53) dias. Ocorreu aumento dos volumes inspiratório e expiratório entre os momentos A5 (antes da manobra) e C1 (imediatamente após aspiração intratraqueal) tanto na manobra com válvula (p = 0,001 e p = 0,009) como sem válvula (p = 0,026 e p = 0,001), respectivamente. Também houve aumento da resistência expiratória entre os momentos A5 e C1 com p = 0,044. Conclusão: Os volumes pulmonares aumentaram na manobra com e sem válvula, havendo diferença significativa no primeiro minuto após a aspiração. Houve diferença significativa na resistência expiratória entre os momentos A5 (antes da manobra) e C1 (imediatamente após aspiração intratraqueal) no primeiro minuto após a aspiração dentro de cada manobra.

ABSTRACT Objective: To assess the effects of manual hyperinflation, performed with a manual resuscitator with and without the positive end-expiratory pressure valve, on the respiratory function of preterm newborns under mechanical ventilation. Methods: Cross-sectional study of hemodynamically stable preterm newborns with gestational age of less than 32 weeks, under mechanical ventilation and dependent on it at 28 days of life. Manual hyperinflation was applied randomly, alternating the use or not of the positive end-expiratory pressure valve, followed by tracheal aspiration for ending the maneuver. For nominal data, the two-tailed Wilcoxon test was applied at the 5% significance level and 80% power. Results: Twenty-eight preterm newborns, with an average birth weight of 1,005.71 ± 372.16g, an average gestational age of 28.90 ± 1.79 weeks, an average corrected age of 33.26 ± 1.78 weeks, and an average mechanical ventilation time of 29.5 (15 - 53) days, were studied. Increases in inspiratory and expiratory volumes occurred between time-points A5 (before the maneuver) and C1 (immediately after tracheal aspiration) in both the maneuver with the valve (p = 0.001 and p = 0.009) and without the valve (p = 0.026 and p = 0.001), respectively. There was also an increase in expiratory resistance between time-points A5 and C1 (p = 0.044). Conclusion: Lung volumes increased when performing the maneuver with and without the valve, with a significant difference in the first minute after aspiration. There was a significant difference in expiratory resistance between the time-points A5 (before the maneuver) and C1 (immediately after tracheal aspiration) in the first minute after aspiration within each maneuver.

RESUMO Introdução O nascimento prematuro acarreta problemas que não se restringem à mortalidade perinatal. Alguns prematuros, mesmo na ausência de lesões cerebrais, apresentam consequências negativas em diversos aspectos do desenvolvimento, como dificuldades em adquirir linguagem. Objetivo O objetivo deste estudo foi verificar o desempenho linguístico de prematuros, na faixa etária de 2 anos, considerando a idade cronológica e a idade corrigida. Métodos Participaram do estudo 23 sujeitos prematuros e para verificar as habilidades linguísticas foi aplicado o Test of Early Language Development – TELD-3. Resultados Os sujeitos prematuros apresentaram desempenho total alterado no TELD-3 em 39,13% dos casos. Os prematuros também foram analisados considerando o atraso para a idade cronológica e a corrigida e não houve diferença no desempenho para os subtestes receptivo (p = 0,250) e expressivo (p = 1,000). Conclusão O grupo de prematuros aos 2 anos de idade constitui população de risco para alterações de linguagem que não podem ser compensadas com a correção da idade.

ABSTRACT Introduction Preterm birth causes problems that are not restricted to perinatal mortality. Some premature, even in the absence of brain damage, have negative effects on various aspects of development, such as language difficulties. Objective This study aimed to verify the linguistic performance of preterm children at 2 years old, considering the chronological age and corrected age. Methods The study included 23 preterm children and applied the Test of Early Language Development- TELD-3 to assess the language skills. Results The premature children showed the linguistic performance alterations in Teld-3 in 39.13% of cases. They were also analyzed considering the delay to the chronological and corrected ages and there was no difference in performance for both receptive subtests (p = 0.250) and significant (p = 1.000). Conclusion The group of premature children at 2 years is a population at risk for language disorders that cannot be compensated with age correction.

RESUMO objetivo: Analisar o comportamento da reparação tecidual de incisão cirúrgica corretiva em neonatos submetidos ao laser de baixa intensidade, auxiliando a redução de incidência de deiscência pós-operatória de correção cirúrgica de mielomeningocele realizada imediatamente após o nascimento. Métodos: Estudo piloto, prospectivo, com 13 pacientes operados ao nascimento de mielomeningocele e submetidos ao laser de baixa intensidade como adjuvante. Foi aplicado, ao longo da incisão cirúrgica, o laser de diodo C.W., λ = 685 nm, p = 21 mW, com E = 0,19 J por ponto, totalizando valores de energia entregue por paciente entre 4 e 10 J, de acordo com a área da cicatriz cirúrgica, e comparando com os resultados obtidos previamente de 23 pacientes operados sem a terapia com o laser (Grupo B). Resultados: Este estudo revelou significativa redução de deiscências no pós-operatório de neonatos, quando submetidos ao laser de baixa intensidade comparados ao controle (7,69 versus 17,39%, respectivamente), evidenciando ser um método de tratamento eficaz, seguro e não-invasivo. Conclusão: Esta nova proposta terapêutica adjuvante com o laser de baixa intensidade auxiliou na reparação tecidual da ferida operatória, evitando morbidades, além de diminuir o tempo de internação, sinalizando possível redução de custos tanto para os pacientes quanto para a instituição.

ABSTRACT Objective: To analyze the tissue repair behavior after corrective surgical incision in neonates submitted to low-level laser therapy, in an attempt to diminish the incidence of postoperative dehiscence following the surgery for myelomeningocele performed immediately after birth. Methods: It is a prospective pilot study with 13 myelomeningocele patients submitted to surgery at birth who received adjuvant treatment with low-level laser therapy (Group A). Diode laser C.W., λ = 685t nm, p = 21 mW, E = 0.19 J was punctually applied along the surgical incision, summing up 4 to 10 J energy delivered per patient, according to the surgical wound area and, then, compared with the previous results, which were obtained from 23 patients undergoing surgery without laser therapy (Group B). Results: This pilot study showed a significant decline in dehiscence of surgical wounds in neonates submitted to low-level laser therapy as compared to controls (7.69 versus 17.39%, respectively), demonstrating this is an effective, safe and noninvasive treatment method. conclusion: This new adjuvant therapeutic proposal with low-level laser therapy aided healing of surgical wounds, preventing morbidities, as well as decreasing hospital stay, which implies cost of reduction for patients and for the institution.

OBJETIVO: Revisar os conhecimentos existentes em relação ao uso de fatores de crescimento epidérmico e estimulador de colônias de granulócitos na prevenção e/ou no tratamento da enterocolite necrosante (ECN) durante o período neonatal. FONTES DE DADOS: Revisão da literatura, nas bases de dados Medline, Lilacs, SciELO e PubMed, utilizando os unitermos "recém-nascidos", "enterocolite" e "fatores de crescimento", no período de 2003 a 2007. Nesta busca, 49 artigos foram encontrados, sendo 17 pertinentes ao tema. Também foram utilizados outros artigos, independente do ano de publicação, relacionados a aspectos definidores da ECN no recém-nascido. SÍNTESE DOS DADOS: A ECN continua sendo responsável por uma elevada morbimortalidade neonatal. Os mecanismos fisiopatológicos vêm sendo elucidados e, a partir deles, são discutidas novas terapias, como o uso de fatores de crescimento, destacando-se o fator de crescimento epidérmico e o fator estimulador de colônias de granulócitos. CONCLUSÕES: O uso de fatores de crescimento no tratamento e prevenção da ECN neonatal parece promissor. É necessário maior número de ensaios clínicos para comprovar sua eficácia e segurança. Enquanto isso, a melhor prática médica continua sendo a prevenção da doença.

OBJECTIVE: To review the literature regarding the use of hematopoietic and epidermic growth factors for prevention or treatment of neonatal necrotizing enterocolitis (NEC). DATA SOURCES: Literature review of Medline, Lilacs, SciELO and Pubmed databases, using the key-words "newborn", "enterocolitis" and "growth factors", from 2003 to 2007. Fourty-nine papers were retrieved, but only 17 related to the subject. Other studies that described some clinical aspects of enterocolitis were also included, regardless of the year of publication. DATA SYNTHESIS: Necrotizing and enterocolitis has been an important cause of morbidity and mortality in the neonatal period. As the knowledge about the pathophysiology of this disease improves, new therapies, such as the administration of epidermal growth factor and granulocyte colony-stimulating factor, are being discussed. CONCLUSIONS: The use of growth factors for treatment and prevention of NEC seems promising. However, further clinics assays are needed to evaluate the effectiveness and the safety of these growth factors. At this moment, the best clinical practice is the prevention of the disease.
