RESUMEN

Objective: To assess the association between sociodemographic and perinatal factors and hospital practices to encourage exclusive breastfeeding in near miss neonates in maternity hospitals. Methods: This is a prospective cohort of live births from the survey "To be born in Brazil" conducted between 2011 and 2012. The weighted number of newborns who met the neonatal near miss criteria was 832. Exclusive breastfeeding at hospital discharge and 45 days after delivery were dependent variables of the study. The sociodemographic and perinatal factors of the puerperal women and hospital practices to encourage breastfeeding were independent variables. The data were analyzed with Poisson regression and set with p value<0.05. Is exclusive breastfeeding in neonatal near misses associated with factors related to sociodemographic conditions, maternal characteristics and the organization of health services? Results: Data from 498 women and their children were analyzed. Mothers with incomplete primary education were more likely (36%) to have exclusive breastfeeding (RR: 1.36; 95% CI: 1.06-1.74) at discharge. Women who did not offer the breast to the newborn in the joint accommodation (65%) were less likely to be breastfeeding exclusively (RR: 0.65; 95% CI: 0.56-0.75) at discharge. Variables that increased the probability of exclusive breastfeeding after 45 days of delivery were primiparity (RR: 1.36; 95% CI: 1.08-1.69) and having the newborn in the delivery room (RR: 1.90; 95% CI: 1.12-3.24). Conclusion: Exclusive breastfeeding in neonatal near misses was associated with maternal characteristics and important hospital practices, such as being breastfed in the joint accommodation and the newborn being in the mother's lap in the delivery room.

RESUMEN

BACKGROUND: Congenital Zika virus (ZIKV) infection leads to severe newborn abnormalities, but its long-term impact on childhood immunity is not well understood. This study aims to investigate the serum proteomics in children exposed to ZIKV during pregnancy to understand potential immunological consequences during early childhood. METHODS: The study included ZIKV-exposed infants (ZEI) at birth (n = 42) and children exposed to ZIKV (ZEC) at two years of age (n = 20) exposed to ZIKV during pregnancy, as well as healthy controls. Serum proteomic analysis was performed on these groups to assess inflammation and immune profiles. Additionally, antibody titres against two common childhood vaccines, DTaP and MMR, were measured in healthy controls (n = 50) and ZEC (n = 92) to evaluate vaccine-induced immunity. FINDINGS: Results showed elevated inflammation in ZEI with birth abnormalities. Among ZEC, despite most having normal clinical outcomes at two years, their serum proteomics indicated a bias towards Th1-mediated immune responses. Notably, ZEC displayed reduced anti-Diphtheria toxin and anti-Clostridium tetani IgG levels against DTaP and MMR vaccines. They also exhibited lower antibody titres particularly against Th2-biased DTaP vaccines, but not Th1-biased MMR vaccines. INTERPRETATION: In conclusion, the study highlights the long-term immunological consequences of congenital ZIKV exposure. Heightened inflammation was observed in ZEI with abnormalities at birth, while ZEC maintained a chronic Th1-biased immune profile. The impaired response to Th2-biased vaccines raises concerns about lasting effects of ZIKV exposure on immune responses. Consequently, there is a need for continued longitudinal clinical monitoring to identify potential immune-related complications arising from prenatal exposure to ZIKV. FUNDING: This work was partially funded by the National Institute of Allergy and Infectious Diseases (NIAID) and National Institute of Dental and Craniofacial Research (NIDCR).

RESUMEN

It is unclear if SARS CoV-2 infection during pregnancy is associated with adverse neurodevelopmental repercussions to infants. We assessed pediatric neurodevelopmental outcomes in children born to mothers with laboratory-confirmed SARS CoV-2 infection during pregnancy. Neurodevelopmental outcomes of in-utero exposed children were compared to that of pre-pandemic control children in Los Angeles (LA), CA, USA and Rio de Janeiro, Brazil. Bayley Scales of Infant and Toddler Development, 3rd edition (Bayley-III), the gold standard tool for evaluating neurodevelopment until 36 months of age and Ages and Stages Questionnaires (ASQ-3), a frequently used screening instrument for evaluating neurodevelopment in this same age group were the assessment tools used. Developmental delay (DD) was defined as having a score < - 2 SD below the norm (< 70) in at least one of three Bayley-III domains, (cognitive, motor or language) or a score below the cut-off (dark zone) in at least one of five ASQ-3 domains (communication, gross motor, fine motor, problem solving, personal-social). Exposed children were born between April 2020 and December 2022 while control children were born between January 2016 to December 2019. Neurodevelopmental testing was performed in 300 children total: 172 COVID-19 exposed children between 5-30 months of age and 128 control children between 6-38 months of age. Bayley-III results demonstrated that 12 of 128 exposed children (9.4%) had DD versus 2 of 128 controls (1.6%), p = 0.0007. Eight of 44 additional exposed children had DD on ASQ-3 testing. Fully, 20 of 172 exposed children (11.6%) and 2 of 128 control children (1.6%), p = 0.0006 had DD. In Rio, 12% of exposed children versus 2.6% of controls, p = 0.02 had DD. In LA, 5.7% of exposed children versus 0 controls, p = 0.12 had DD. Severe/critical maternal COVID-19 predicted below average neurodevelopment in the exposed cohort (OR 2.6, 95% CI 1.1-6.4). Children exposed to antenatal COVID-19 have a tenfold higher frequency of DD as compared to controls and should be offered neurodevelopmental follow-up.

RESUMEN

OBJECTIVE: To evaluate the growth trajectory of head circumference and neurodevelopment, and to correlate head circumference with cognitive, language, and motor outcomes during the first two years. METHOD: Prospective cohort study in a tertiary hospital including 95 newborns under 32 weeks or 1500 g. Neonates who developed major neonatal morbidities were excluded. The head circumference was measured at birth, at discharge, and at term-equivalent age, 1, 3, 5, 12, 18, and 24 months of corrected age, and the Bayley Scales (Bayley-III) were applied at 12, 18 and 24 months of corrected age to assess cognitive, language and, motor domains. Scores below 85 were classified as mild/moderate deficits and scores below 70 as severe deficits. The association between head circumference Z score and Bayley scores was assessed using Pearson's correlation. The study considered a significance level of 0.05. RESULTS: There was a decrease of -0.18 in the head circumference Z score between birth and discharge and the catch-up occurred between discharge and 1 month (an increase of 0.81 in the Z score). There was a positive correlation between head circumference and Bayley scores at 18 months. There was also a positive correlation between head circumference at discharge and at 5 months with the three domains of the Bayley. CONCLUSION: Serial measurements of head circumference provide knowledge of the trajectory of growth, with early catch-up between discharge and 1 month, as well as its association with neurodevelopment. Head circumference is therefore a valuable clinical marker for neurodevelopment, especially in very preterm newborns.

RESUMEN

Compared with full-term infants, preterm infants have fat-free mass deficit in the first months of life, which increases the risk of metabolic diseases in the future. In this cohort of children born under 32-week gestational age or less than 1500 g, we aimed to evaluate the associations of body composition at term equivalent age and in the first 3 months of life with fat-free mass and fat mass percentage at 4 to 7 years of life. Body composition assessments by air displacement plethysmography and anthropometry were performed at term, at 3 months of corrected age, and at 4 to 7 years of age. Multiple linear regression analysis was used to observe the associations between body composition at these ages. At term, fat mass percentage showed a negative association and fat-free mass a positive association with fat-free mass at 4 to 7 years. The fat-free mass at 3 months and the gain in fat-free mass between term and 3 months showed positive associations with fat-free mass at 4 to 7 years.   Conclusion: Body composition at preschool age is associated with fat-free mass in the first 3 months of life, a sensitive period for the risk of metabolic diseases. What is Known: • Preterm infants have a deficit in fat-free mass and high adiposity at term equivalent age compared to full-term infants. • Fat-free mass reflects metabolic capacity throughout life and therefore is considered a protective factor against the risk of metabolic syndrome. What is New: •Fat-free mass gain in the first 3 months of corrected age is associated with fat-free mass at preschool and school ages. •The first 3 months of life is a sensitive period to the risk of metabolic diseases.

RESUMEN

To evaluate the influence of early nutritional intake on the growth pattern of very preterm infants. This was an observational study including 109 newborns (< 32 weeks gestational age). Perinatal morbidities, nutritional therapy (first four weeks of life), and weight, length, and head circumference (HC) growth at term-equivalent age were evaluated. Growth restriction was defined as a difference > 1.2 SD between the birth and term age measurements. Growth restriction at term-equivalent age: 52.3% (weight), 42.9% (length), and 22% (HC). Morbidities were positively correlated with nutrition therapy and negatively correlated with the total energy provision: protein ratio. The duration of parenteral nutrition, the time to reach full enteral feedings, and the total energy provision: protein ratio were significantly correlated. Nutrient intake influenced weight, length, and HC growth, and cumulative energy deficit was significantly associated with HC growth restriction.   Conclusion: Perinatal morbidities interfere with nutritional therapy and early nutrient intake, leading to insufficient energy and energy provision: protein ratio for growth. What is Known: • The intake of macronutrients early in life, mainly protein, is important for the optimal growth of pretem infants. • The severity of morbidities and low gestational ages impact the nutritional management of preterm infants. What is New: • The number of morbidities, reflecting the severity of the neonatal clinical course, had a detrimental effect on the nutritional therapy and nutrients intake. • The inadequate energy provision per gram of protein ratio was significantly associated with growth restriction in all growth measures at the second week of life, persisting for head circumference up to the fourth week, highlighting the importance of its measurement, as it could be a precocious sign of development risk.

RESUMEN

Zika virus (ZIKV) infections during pregnancy can result in Congenital Zika Syndrome (CZS), a range of severe neurological outcomes in fetuses that primarily occur during early gestational stages possibly due to placental damage. Although some placentas can maintain ZIKV persistence for weeks or months after the initial infection and diagnosis, the impact of this viral persistence is still unknown. Here, we aimed to investigate the immunological repercussion of ZIKV persistence in term placentas. As such, term placentas from 64 pregnant women diagnosed with Zika in different gestational periods were analyzed by ZIKV RT-qPCR, examination of decidua and placental villous histopathology, and expression of inflammation-related genes and IFNL1-4. Subsequently, we explored primary cultures of term decidual Extravillous Trophoblasts (EVTs) and Term Chorionic Villi (TCV) explants, as in vitro models to access the immunological consequences of placental ZIKV infection. Placenta from CZS cases presented low IFNL1-4 expression, evidencing the critical protective role of theses cytokines in the clinical outcome. Term placentas cleared for ZIKV showed increased levels of IFNL1, 3, and 4, whether viral persistence was related with a proinflammatory profile. Conversely, upon ZIKV persistence placentas with decidual inflammation showed high IFNL1-4 levels. In vitro experiments showed that term EVTs are more permissive, and secreted higher levels of IFN-α2 and IFN-λ1 compared to TCV explants. The results suggest that, upon ZIKV persistence, the maternal-skewed decidua contributes to placental inflammatory and antiviral signature, through chronic deciduitis and IFNL upregulation. Although further studies are needed to elucidate the mechanisms underlying the decidual responses against ZIKV. Hence, this study presents unique insights and valuable in vitro models for evaluating the immunological landscape of placentas upon ZIKV persistence.

RESUMEN

Brazil has made advances in obstetric care in public and private hospitals; however, weaknesses in this system still require attention. The Brazilian Ministry of Health, aware of this need, funded the second version of the Birth in Brazil survey. This study aimed to evaluate: prenatal, labor and birth, postpartum, and abortion care, comparing the results with those of Birth in Brazil I; and analyze the main determinants of perinatal morbidity and mortality; evaluate the care structure and processes of obstetrics and neonatology services in maternity hospitals; analyze the knowledge, practices, and attitudes of health professionals who provide birth and abortion care; and identify the main barriers and facilitators related to care of this nature in Brazil. With a national scope and a 2-stage probability sample: 1-hospitals and 2-women, stratified into 59 strata, 465 hospitals were selected with a total planned sample of around 24,255 women - 2,205 for abortion reasons and 22,050 for labor reasons. Data collection was conducted using six electronic instruments during hospital admission for labor or abortion, with two follow-up waves, at two and four months. In order to expand the number of cases of severe maternal morbidity, maternal and perinatal mortality, three case control studies were incorporated into Birth in Brazil II. The fieldwork began in November 2021 and is scheduled to end in 2023. It will allow a comparison between current labor and birth care results and those obtained in the first study and will evaluate the advances achieved in 10 years.

RESUMEN

A number of studies have focused on the evaluation of the relationship between pre-pregnancy overweight and polyunsaturated fatty acids content in human milk. However, given the complexity of potentially confounding risk factors, the use of graphical tools is recommended to identify possible biases. This article aims to propose a theoretical model of causality using the directed acyclic graph between pre-pregnancy overweight and polyunsaturated fatty acids content in human milk. Methods: An extensive literature review was performed to identify variables with causal relationships with exposure and/or outcome. The choice of variables for adjustment followed the graphic algorithm that comprises six criteria for selecting a minimum set of potentially confounding variables. Socioeconomic conditions, interpartum interval, maternal age and food consumption pattern were the variables that would have to be adjusted in order to estimate the total effect of pre-pregnancy overweight on polyunsaturated fatty acids content in human milk. The minimum set of variables found in the present study can be used in the analysis of other studies that evaluate this association.

Inúmeros estudos têm se detido na avaliação da associação entre o excesso de peso pré-gestacional e os ácidos graxos poli-insaturados no leite humano. Todavia, diante da complexidade de fatores de risco potencialmente confundidores, é recomendável a utilização de ferramentas gráficas para identificar possíveis vieses. O objetivo deste artigo é propor um modelo teórico de causalidade utilizando o gráfico acíclico direcionado entre o excesso de peso pré-gestacional e os ácidos graxos poli-insaturados no leite humano. Foi realizada ampla revisão da literatura para identificar as variáveis com relações causais com a exposição e/ou desfecho. A escolha das variáveis para ajuste seguiu o algoritmo gráfico que compreende seis critérios para a seleção de um conjunto mínimo de variáveis potencialmente confundidoras. Condições socioeconômicas, intervalo interpartal, idade materna e padrão de consumo alimentar foram as variáveis ajustadas a fim de se estimar o efeito total do excesso de peso pré-gestacional sobre o conteúdo dos ácidos graxos poli-insaturados no leite humano. O conjunto mínimo de variáveis encontrado pelo presente estudo pode ser utilizado na análise de outros estudos que avaliem essa associação.

RESUMEN

ABSTRACT Objective: The objective of this study was to evaluate the influence of maternal and perinatal factors on the nutritional composition of human milk. Methods: A cross-sectional study was conducted between November 2018 and January 2020, with 181 donors selected in Tertiary Health Units of the Unified Health System — from one collection station and five Human Milk Banks. Data were collected through a standardized questionnaire. To be fit to be a donor in a Human Milk Banks and produce mature milk were the eligibility criteria to participate in the study. We excluded milk samples with Dornic acidity above 8° D. The dependent variables were the macronutrients of human milk (i.e., carbohydrates, proteins, lipids, and total energy), that were analyzed using spectroscopy with the Miris Human Milk Analyzer™. The maternal and perinatal factors were the independent variables. Results: Women with pre-gestational obesity and gestational weight gain above the recommendation showed a lower protein concentration compared to eutrophic women (median=0.8, interquartile range (IQR): 0.7-0.9 vs. median=0.8, and IQR: 0.8-1.0) and those with adequate gestational weight gain (median=0.8, IQR: 0.7-0.9 vs. median=0.9, and IQR: 0.8-1.0), respectively. The other analyzed factors (i.e., maternal habits, comorbidities, and perinatal factors) were not associated with the nutritional composition of human milk. Conclusions: The assessment of factors associated with the nutritional composition of human milk is extremely important to assist postpartum care. Pre-gestational obesity and inadequate gestational weight gain were the only factors statistically associated with the nutritional composition of human milk as they impacted its protein content.

RESUMO Objetivo: Avaliar a influência de fatores maternos e perinatais na composição nutricional do leite humano. Métodos: Estudo transversal, realizado entre novembro de 2018 e janeiro de 2020, com 181 doadoras selecionadas em Unidades Terciárias de Saúde do Sistema Único de Saúde de um Posto de Coleta e cinco Bancos de Leite Humano. Foram coletados dados das variáveis maternas e dos recém-nascidos por meio de questionário padronizado. Estar apta para ser doadora em um Banco de Leite Humano e produzir leite maduro foram os critérios de elegibilidade para participar do estudo. As amostras de leite com acidez Dornic acima de 8° D foram excluídas. Os macronutrientes do leite humano, variáveis dependentes (carboidratos, proteínas, lipídeos, energia total) foram analisados pela técnica de espectroscopia de transmissão no infravermelho médio com o Miris Human Milk Analyzer™. Os fatores maternos e perinatais foram as variáveis independentes. Resultados: Mulheres com obesidade pré-gestacional e ganho de peso gestacional acima do recomendado apresentaram menor concentração proteica em relação às eutróficas (mediana=0,8, intervalo interquartil [IQR]: 0,7-0,9 vs. mediana=0,8, IQR: 0,8-1,0) e aquelas com ganho de peso gestacional adequado (mediana=0,8, IQR: 0,7-0,9 vs. mediana=0,9, IQR: 0,8-1,0), respectivamente. Os demais fatores analisados (hábitos maternos, comorbidades, fatores perinatais) não se associaram com a composição nutricional do leite humano. Conclusões: A avaliação dos fatores associados à composição nutricional do leite humano é de extrema importância para auxiliar os cuidados pós-parto. A obesidade pré-gestacional e o ganho de peso gestacional inadequado foram os únicos fatores estatisticamente associados com a composição nutricional do leite humano por terem impactado o seu teor de proteína.

RESUMEN

Abstract Introduction The pregnant woman's card is one of the instruments used to evaluate prenatal care. It is an important source of data for epidemiological survey, being essential to ensure the flow of information and contribute to the continuity of care. Objective: Analyze studies that focused on the evaluation of the completeness of the pregnant woman's card. Methods A systematic review was carried out in the Scielo, Virtual Health Library, EMBASE, and Web of Science databases and the checklist based on the Preferred Reporting Items for Systematic Reviews (PRISMA) guideline was used. Results Forty-three studies were identified, resulting in seven analyzed. The studies showed methodological differences, especially regarding the fields of the pregnant woman's card selected for analysis, method of presentation and interpretation of results, ranging from relative frequency with different categories to classification by Romero & Cunha score. This divergence limited the comparison of findings. Even so, all studies observed poor completeness in important fields of the maternity card. Conclusion It is extremely important that professionals and managers value the full completion of the pregnant woman's card, favoring the assessment of care and decision-making during prenatal care.

Resumo Introdução O cartão da gestante é um dos instrumentos utilizados para avaliar o pré-natal. É importante fonte de dados para levantamento epidemiológico, sendo fundamental para garantir fluxo de informações e contribuir para a continuidade do cuidado. Objetivo: Analisar estudos que se detiveram na avaliação da completitude do cartão da gestante. Métodos Realizou-se revisão sistemática nas bases de dados Scielo, Biblioteca Virtual em Saúde, EMBASE e Web of Science e utilizou-se a checklist com base na diretriz Preferred Reporting Items for Systematic Reviews (PRISMA). Resultados Quarenta e três estudos foram identificados, resultando em sete analisados. Os estudos apresentaram diferença metodológica, sobretudo quanto aos campos do cartão da gestante selecionados para análise, método de apresentação e interpretação de resultados, variando da frequência relativa com diferentes categorias à classificação pelo score de Romero & Cunha. Essa divergência limitou a comparação dos achados. Ainda assim, todos os estudos observaram completitude ruim em campos importantes do cartão da gestante. Conclusão É extremamente importante que profissionais e gestores valorizem o preenchimento integral do cartão da gestante, favorecendo a avaliação da assistência e a tomada de decisão durante o pré-natal.

RESUMEN

Resumo A infecção pelo vírus Zika na grávida resulta em alterações do desenvolvimento neuropsicomotor nas crianças afetadas, sendo importante fator de estresse para essas mulheres. O objetivo deste estudo foi avaliar a estratégia de enfrentamento das mães a essa situação e como isto se refletiu no neurodesenvolvimento dos seus filhos. Estudo transversal com 46 mulheres e seus filhos. A estratégia de enfrentamento foi avaliada pelo Inventário Brief Cope, aplicado às mães, e o desenvolvimento neuropsicomotor das crianças, foi avaliado aos 24 meses de idade pelas Escalas Bayley III. A estratégia predominante de enfrentamento mais frequentemente usada pelas mães foi a de aproximação (73,9%), com destaque para o componente planejamento. A utilização da estratégia de negação esteve associada aos escores mais baixos na escala Bayley III, sendo nessa escala o componente mais utilizado o de auto culpabilização. A religião foi o componente de apoio auxiliar mais utilizado pelas mães. A utilização da negação como estratégia predominante de enfrentamento pelas mães mostrou associação com os piores resultados na avaliação do desenvolvimento infantil e reforça a necessidade do apoio a estas mulheres, para que possam lidar mais diretamente com os sentimentos decorrentes das situações vivenciadas.

Abstract Zika virus infection in pregnant women results in changes in neuropsychomotor development in affected children, being an important stress factor for these women. This study aimed to evaluate the mothers' coping strategy in this situation and how this was reflected in the neurodevelopment of their children. Cross-sectional study with 46 women and their children. The coping strategy was assessed using the Brief Cope Inventory, applied to mothers, and the children's neuropsychomotor development was assessed at 24 months of age using the Bayley III Scales. The predominant coping strategy most frequently used by mothers was approach (73.9%), with emphasis on the planning component. The use of the avoidant coping was associated with lower scores on the Bayley III scale, with self-blame being the most used component on this scale. Religion was the auxiliary support component most used by mothers. The use of avoidant as the predominant coping strategy by mothers was associated with the worst results in the assessment of child development and reinforces the need to support these women, so that they can deal more directly with the feelings arising from the situations they experience.

RESUMEN

Objetivo: Avaliar os desfechos neonatais adversos e fatores associados entre gestantes com diabetes mellitus gestacional e de risco gestacional habitual. Métodos: Estudo transversal, de âmbito nacional e de base hospitalar, conduzido entre fevereiro de 2011 e outubro de 2012. Foram excluídas as mulheres com gestações múltiplas ou natimortos. As informações foram coletadas via questionário padronizado, cartão de pré-natal e/ou prontuário. Resultados: Das 12.712 puérperas avaliadas, 1.915 tinham diabetes mellitus gestacional e 10.797 foram classificadas em risco gestacional habitual. Verificou-se que 74,1% das mulheres com diabetes receberam assistência pré-natal adequada/mais que adequada em relação a 65% das mulheres com risco gestacional habitual. Em contrapartida, o grupo das mulheres com diabetes foi composto em sua maioria por mulheres acima de 35 anos, com hipertensão prévia, excesso de peso pré-gestacional e ganho de peso gestacional excessivo, multíparas, com histórico de cesárea e abortos. Os desfechos "prematuridade" e "nascimento de recém-nascido grande para idade gestacional" foram superiores entre as mulheres com diabetes. Conclusão: As mulheres com diabete detiveram condições demográficas, antecedentes clínicos/obstétricos e desfechos neonatais mais desfavoráveis em relação às mulheres de risco gestacional habitual. Apesar disso, o pré-natal foi um dos fatores que exerceu extrema importância para que outros desfechos negativos (óbito neonatal e o Apgar<5) não fossem superiores entre as mulheres com diabete sem relação às de risco gestacional habitual. Portanto, reitera-se o papel do pré-natal entre as mulheres brasileiras, sobretudo as de alto risco gestacional.

Objective: To assess adverse neonatal outcomes and associated factors between pregnant women with gestational diabetes mellitus and usual gestational risk. Methods: Cross-sectional, nationwide, hospital-based study, conducted from February 2011 to October 2012. Women with multiple pregnancies or stillbirths were excluded. Information was collected using a standardized questionnaire, prenatal card and/or medical records. Results: Out of a total of 12,712 postpartum women evaluated, 1,915 had gestational diabetes mellitus and 10,797 were classified as usual gestational risk. It was observed that 74.1% of diabetics received adequate/more than adequate prenatal care compared to 65% of women with usual gestational risk. On the other hand, the group of diabetics was composed mostly of women over 35 years of age, with underlying hypertension, pre-gestational excess weight and excess gestational weight gain who were multiparous, with history of cesarean deliveries and abortions. The outcomes of "prematurity" and "birth of large-sized newborn" for the gestational age were higher among diabetics. Conclusion: Diabetic women had more unfavorable demographic conditions, clinical/obstetric history and neonatal outcomes compared to women with usual gestational risk. Nevertheless, prenatal care was a factor of extreme importance to prevent other negative outcomes (neonatal death and Apgar <5) to increase among diabetic women compared to those with usual gestational risk. Therefore, the role of prenatal care among Brazilian women is reiterated, especially among the high gestational risk women.

RESUMEN

Abstract Objective To assess the association between sociodemographic and perinatal factors and hospital practices to encourage exclusive breastfeeding in near miss neonates in maternity hospitals. Methods This is a prospective cohort of live births from the survey "To be born in Brazil" conducted between 2011 and 2012. The weighted number of newborns who met the neonatal near miss criteria was 832. Exclusive breastfeeding at hospital discharge and 45 days after delivery were dependent variables of the study. The sociodemographic and perinatal factors of the puerperal women and hospital practices to encourage breastfeeding were independent variables. The data were analyzed with Poisson regression and set with p value<0.05. Is exclusive breastfeeding in neonatal near misses associated with factors related to sociodemographic conditions, maternal characteristics and the organization of health services? Results Data from 498 women and their children were analyzed. Mothers with incomplete primary education were more likely (36%) to have exclusive breastfeeding (RR: 1.36; 95% CI: 1.06-1.74) at discharge. Women who did not offer the breast to the newborn in the joint accommodation (65%) were less likely to be breastfeeding exclusively (RR: 0.65; 95% CI: 0.56-0.75) at discharge. Variables that increased the probability of exclusive breastfeeding after 45 days of delivery were primiparity (RR: 1.36; 95% CI: 1.08-1.69) and having the newborn in the delivery room (RR: 1.90; 95% CI: 1.12-3.24). Conclusion Exclusive breastfeeding in neonatal near misses was associated with maternal characteristics and important hospital practices, such as being breastfed in the joint accommodation and the newborn being in the mother's lap in the delivery room.

RESUMEN

OBJECTIVE: The objective of this study was to evaluate the influence of maternal and perinatal factors on the nutritional composition of human milk. METHODS: A cross-sectional study was conducted between November 2018 and January 2020, with 181 donors selected in Tertiary Health Units of the Unified Health System - from one collection station and five Human Milk Banks. Data were collected through a standardized questionnaire. To be fit to be a donor in a Human Milk Banks and produce mature milk were the eligibility criteria to participate in the study. We excluded milk samples with Dornic acidity above 8° D. The dependent variables were the macronutrients of human milk (i.e., carbohydrates, proteins, lipids, and total energy), that were analyzed using spectroscopy with the Miris Human Milk Analyzer™. The maternal and perinatal factors were the independent variables. RESULTS: Women with pre-gestational obesity and gestational weight gain above the recommendation showed a lower protein concentration compared to eutrophic women (median=0.8, interquartile range (IQR): 0.7-0.9 vs. median=0.8, and IQR: 0.8-1.0) and those with adequate gestational weight gain (median=0.8, IQR: 0.7-0.9 vs. median=0.9, and IQR: 0.8-1.0), respectively. The other analyzed factors (i.e., maternal habits, comorbidities, and perinatal factors) were not associated with the nutritional composition of human milk. CONCLUSIONS: The assessment of factors associated with the nutritional composition of human milk is extremely important to assist postpartum care. Pre-gestational obesity and inadequate gestational weight gain were the only factors statistically associated with the nutritional composition of human milk as they impacted its protein content.

RESUMEN

We aimed to identify the reports of symptoms of depression, anxiety, and stress among caregivers of children without visual impairment, with low vision, and with blindness and their relationship with the degree of social, emotional, material, and affective support. This cross-sectional and multicenter study was conducted in the municipality of Rio de Janeiro, Brazil, from 2019 to 2020. A questionnaire was applied to obtain caregivers' sociodemographic and economic data. The Medical Outcomes Study Social Support Scale (MOS-SSS) and The Depression, Anxiety, and Stress Scale (DASS-21) were used. Tests were used for multiple comparisons of these scales. The prevalence ratio of symptoms of depression, anxiety, and stress was estimated. Of all caregivers (N = 355), more than 90% were women-mothers. Caregivers of children with visual impairment show the highest proportion of no schooling, incomplete elementary education, or lower average monthly income. Most caregivers of children with blindness reported symptoms of depression, anxiety, and stress (66.7%, 73.3%, and 80%, respectively) as did those of children with low vision. The evaluation of the relationship between MOS-SSS and DASS-21 results shows greater support and lower scores of reports of depression, anxiety, and stress for caregivers of children without disabilities or with less visual impairment. For caregivers of blind children, the highest prevalence of such reports was independent of the received support. Results indicate the need for a care policy with mechanisms to protect the mental health of caregivers of visually impaired children.

O objetivo foi identificar os relatos de sintomas de depressão, ansiedade e estresse entre cuidadores de crianças sem deficiência visual, com baixa visão e com cegueira e sua relação com o grau de apoio social, emocional, material e afetivo. Estudo transversal e multicêntrico, realizado no Município do Rio de Janeiro, Brasil, entre 2019 e 2020. Aplicou-se um questionário para obter dados sociodemográficos e econômicos do cuidador. Foram utilizadas a Escala de Apoio Social (The Medical Outcomes Study Social Support Scale - MOS-SSS) e a Escala de Depressão, Ansiedade e Estresse (The Depression, Anxiety, and Stress Scale - DASS-21). Na comparação entre as escalas, foram utilizados testes para comparações múltiplas. Estimou-se a razão de prevalência de sintomas de depressão, ansiedade e estresse. Do total de cuidadores (N = 355), mais de 90% eram mulheres-mães e a maior proporção de cuidadores sem instrução ou Ensino Fundamental incompleto e com menor renda média mensal foi daqueles de crianças com deficiência visual. A maioria dos cuidadores de crianças com cegueira relatou sintomas de depressão, ansiedade e estresse (respectivamente, 66,7%, 73,3% e 80%), mesmo comportamento observado no grupo de cuidadores de crianças com baixa visão. Na avaliação da relação entre os resultados das escalas MOS-SSS e DASS-21, entre os cuidadores de crianças sem deficiência ou com menor comprometimento visual, observou-se maiores apoios e menores escores de relatos de depressão, ansiedade e estresse. Entre os cuidadores de crianças cegas, as maiores prevalências não dependeram dos apoios recebidos. Os resultados indicam a necessidade de uma política de cuidado com mecanismos de proteção à saúde mental dos cuidadores de crianças com deficiência visual.

RESUMEN

INTRODUCTION: Congenital Zika syndrome (CZS) is a recently described disease. Our main objective was to evaluate and monitor, over 3 years, the ophthalmoscopic findings in children exposed to zika virus (ZIKV) during gestation. METHODS: This prospective observational study was conducted in Rio de Janeiro, Brazil, between April 2016 and May 2019. We evaluated two groups with exanthema serving as a proxy for viremia: (i) children whose mothers had exanthema during pregnancy and (ii) children who had microcephaly without maternal exanthema during pregnancy. We performed indirect ophthalmoscopy at recruitment and every 6 months thereafter. We also tested the association between ocular findings with maternal exanthema, microcephaly, CZS and maternal infection confirmed by reverse transcriptase quantitative polymerase chain reaction and gender. RESULTS: Of the 72 children included, 16 (22.2%) had optic nerve and/or retinal lesions. All 16 had CZS and 15 (93.7%) had microcephaly (14 at birth and 1 postnatally). The child with postnatally acquired microcephaly was born to a mother without exanthema during pregnancy. Fifty-six (77.8%) of the 72 children were followed for a median time of 24 months and none exhibited differences between admission and follow-up examinations. After logistic regression, only microcephaly at birth was associated with eye abnormalities (odds ratio, 77.015; 95% confidence interval, 8.85-670.38; p < 0.001). CONCLUSION: We observed that there was no progression of the lesions over the follow-up period. We also showed that the eye findings were associated only with microcephaly at birth. Attention should be paid to all children born during a ZIKV epidemic, regardless of maternal exanthema and/or microcephaly at birth.

RESUMEN

OBJECTIVE: To evaluate the effect of colostrum therapy on days to start a suckling diet in newborns diagnosed with simple gastroschisis. METHODS: Randomized clinical trial with newborns diagnosed with simple gastroschisis at a federal hospital in Rio de Janeiro who were randomized to receive oropharyngeal administration of 0.2mL of colostrum or a "sham procedure" during the first 3 days of life. The analysis included clinical outcomes such as days without food, days with parenteral feeding, days until the start of enteral feeding, days to reach complete enteral feeding, sepsis and length of hospital stay. RESULTS: The onset of oral feeding (suction) in patients with simple gastroschisis in both groups occurred at a median of 15 days. CONCLUSION: The present study showed that there were no significant differences in the use of colostrum therapy and the number of days to the start of enteral feeding and suction diet between groups of newborns with simple gastroschisis.
