Language delay was associated with a smaller head circumference at birth in asymptomatic infants prenatally exposed to the Zika virus.

AIM: Our aim was to analyse 12-month outcomes of children who were prenatally exposed to the Zika virus and asymptomatic at birth. METHODS: This was an observational, exploratory study of infants exposed to the Zika virus during gestation and born between March 2016 and April 2017 without congenital Zika syndrome. They were followed until the age of 22 months. The outcome measure was neurodevelopment at 12 months of life, which was evaluated with the Bayley Scales of Infant and Toddler Development, Third edition (Bayley-III). The scores were adjusted for maternal education and prematurity. RESULTS: A total of 96 infants were included in the study and 35.4% scored below the normal range in at least one Bayley-III domain. The majority (91.2%) of the infants with delayed scores presented with language delay, which was not associated with the gestational age at exposure. Receptive language was more affected by exposure than expressive language (27.0% vs 19.8%). There was a direct, and significant, association between the head circumference Z-score at birth and language delay. CONCLUSION: Language delay was associated with a smaller head circumference at birth in infants prenatally exposed to the Zika virus and born asymptomatic. This may indicate future learning difficulties.

Plasma and breast milk adipokines in women across the first year postpartum and their association with maternal depressive symptoms and infant neurodevelopment: Protocol for the APPLE prospective cohort study.

INTRODUCTION: Adiponectin and leptin play important roles in the central nervous system. During the postpartum period, there is a need for a better understanding of the relationship between these cytokines and the neurological development of the infant, as well as their influence on preventing maternal depressive symptoms. OBJECTIVES: To assess the correlation between adiponectin and leptin in maternal plasma and breast milk and their association with: infant neurodevelopment at 6 and 12 months of age; and maternal mental health over the first year postpartum. METHODS: Prospective cohort study with four follow-up. Mothers and their newborns are recruited within the first 15 days postpartum (baseline). Follow-up visits occur at 2, 6, and 12 months postpartum. Visits include blood and breast milk collection, application of the Edinburgh Postnatal Depression Scale and Beck Depression Inventory to assess maternal mental health, application of the Bayley-III scale for infant developmental assessment, maternal and infant anthropometry and body composition, evaluation of reproductive history, mother-infant bonding, breastfeeding, consumption of ultra-processed foods, sleep quality, and socio-economic and demographic data. RESULTS: The research received funds in August 2022, and participant recruitment began in September 2022. The sample size will consist of 95 mother-child pairs. As of September 2023, 68 participants have been recruited. CONCLUSION: The project will provide insights into the association between adiponectin and leptin with postpartum depression and infant neurodevelopment, ultimately promoting improved care and quality of life for these groups. Additionally, it will provide data on the type of delivery, infant physical growth, maternal and infant body composition changes, sleep quality, consumption of ultra-processed foods, and maternal metabolic health, including vitamin D metabolites, oxidized polyunsaturated fatty acid metabolites, phospholipid species and triacylglycerols, which are of significant relevance to public health and, when interconnected, may yield important results and contribute to the existing literature. TRIAL REGISTRATION: Name of the registry: Brazilian Clinical Trials Registry (ReBec). Registration number: RBR-9hcby8c.

High-risk children and social isolation: the importance of family functioning.

High-risk newborns are exposed to neonatal conditions such as prematurity, very low birth weight, and congenital malformations that can affect development and behavior. Coronavirus disease 2019 (COVID-19) restraint and control measures have been identified as important stressor events and cumulative risk factors for behavioral changes in these children. This study examined social isolation-related factors that contribute to internalizing and externalizing behavior problems in children already at risk for neurodevelopmental disorders. This cross-sectional, multicenter study included 113 children (18 months to 9 years) who were followed in reference services for neonatal follow-up in tertiary units of the public health system in the city of Rio de Janeiro, Brazil. Behavior was assessed using the child behavior checklist, and a structured questionnaire was used to assess sociodemographic aspects. In the bivariate analysis, prematurity was associated with externalizing problems and change in eating habits with internalizing problems. The logistic model indicated that both parents having completed high school and both sharing care of the child were protective factors for behavioral problems; however, reports of sleep problems and living with another child were risk factors. In conclusion, the study identified internalizing and externalizing behavior problems related to prematurity and aspects of family structure and routine in children at risk. The findings confirm the importance of family functioning for child health and family-centered interventions.

Neurodevelopment of children exposed intra-uterus by Zika virus: A case series.

The main goal of this manuscript was to investigate the neurodevelopment of children exposed by Zika virus in the intrauterine period who are asymptomatic at birth. Newborns with documented Zika virus exposure during the intrauterine period who were asymptomatic at birth were followed in the first two years of life for neurodevelopment using Bayley III test. Children were classified as having normal or delayed neurodevelopment for age based on most recent Bayley III evaluation results. Eighty-four infants were included in the study. The first Bayley III evaluation was performed at a mean chronological age of 9.7±3.1 month; 13 children (15%) had a delay in one of the three domains, distributed as follow: 10 (12%) in the language domain and 3 (3.5%) in the motor domain. The most recent Bayley III evaluation was performed at a mean age 15.3±3.1 months; 42 children (50%) had a delay in one of the three domains: 4 (5%) in cognition, 31 (37%) in language, and 20 (24%) in motor performance. There were no statistical differences in Gender, Gestational Age, Birth Weight and Head Circurference at birth between children with normal and delayed neurodevelopment for age. A very high proportion of children exposed ZIKV during pregnancy who were asymptomatic at birth demonstrated a delay in neurodevelopment, mainly in the language domain, the first two years of life.

Estratégia materna de enfrentamento à confirmação de infecção pelo vírus Zika na gravidez: reflexo no neurodesenvolvimento dos seus filhos / Maternal strategy for coping with confirmation of Zika virus infection during pregnancy: reflection on the neurodevelopment of their children

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.

Neurodevelopment of children exposed intra-uterus by Zika virus: a case series

O principal objetivo deste manuscrito foi investigar o neurodesenvolvimento de crianças expostas ao vírus Zika no período intra-uterino, assintomáticas ao nascimento. Recém-nascidos com exposição documentada ao vírus Zika durante o período intra-uterino que eram assintomáticos ao nascimento foram acompanhados nos dois primeiros anos de vida para o desenvolvimento neurológico usando o teste de Bayley III. As crianças foram classificadas como tendo neurodesenvolvimento normal ou tardio para a idade, com base nos resultados mais recentes da avaliação de Bayley III. Oitenta e quatro crianças foram incluídas no estudo. A primeira avaliação de Bayley III foi realizada com idade cronológica média de 9,7 ± 3,1 meses; 13 crianças (15%) apresentaram atraso em um dos três domínios, distribuídos da seguinte forma: 10 (12%) no domínio da linguagem e 3 (3,5%) no domínio motor. A avaliação mais recente de Bayley III foi realizada com idade média de 15,3 ± 3,1 meses; 42 crianças (50%) apresentaram atraso em um dos três domínios: 4 (5%) em cognição, 31 (37%) em linguagem e 20 (24%) em desempenho motor. Não houve diferenças estatísticas em gênero, idade gestacional, peso ao nascer e circunferência da cabeça ao nascer entre crianças com neurodesenvolvimento normal e tardio para a idade. Uma proporção muito alta de crianças expostas ao ZIKV durante a gravidez, assintomáticas ao nascimento, demonstrou um atraso no desenvolvimento neurológico, principalmente no domínio da linguagem, nos primeiros dois anos de vida.
