Assessment of Affordances in the Home Environment and Neurodevelopment of Children With Congenital Zika Syndrome.

BACKGROUND: Congenital Zika syndrome (CZS) is characterized by brain abnormalities caused by in utero exposure to the Zika virus (ZIKV), resulting in significant neurodevelopmental, motor and visual impairments in affected children. These impairments hinder their ability to engage in social interactions and explore their surroundings. However, personalized and continuous sensory stimulation, particularly within the home environment, may play a crucial role in supporting motor and visual development in these children. Therefore, this study aimed to explore the relationship between sensory stimulation in the home environment and the motor and visual development of children with CZS. METHOD: This cross-sectional study included children with CZS. The Affordances in the Home Environment for Motor Development (AHEMD) instrument was administered to caregivers to assess motor stimulation opportunities at home. All children underwent neurodevelopmental milestone assessments using the Brazilian Portuguese version of the Bayley Scales of Infant Development-Third Edition (BSID-III). Gross motor function was further assessed with the Gross Motor Function Measure (GMFM), and functional vision was evaluated by using the functional vision developmental milestones test (FVDMT). RESULTS: Eighty-five children with a mean age of 39.9 ± 2.3 (24.0-42.0) months were included. Forty-one children (48.2%) lived in homes with 'very weak' environmental stimulation. The children showed profound developmental delays in all domains of the BSID-III with an average neurodevelopmental age of 39.9 ± 2.3 (24-42) months. On the GMFM, over 90.0% of children could not initiate or maintain the required movements and postures for sitting, crawling, standing, walking, running and jumping. A significant positive correlation was found between the variety of home sensory stimulation with the AHEMD and the scores at the BSID-III motor scales as well as the GMFM. More fine motor materials in the home context correlated with better gross motor scores on the BSID-III (p = 0.016), increased likelihood of passing the 'sitting' (p = 0.041) and 'standing' (p = 0.019) items of the GMFM. Children with less visual impairment in parameters of the FVDMT ['eye contact' (p = 0.032), 'social smile' (p = 0.031) and 'movements to achieve' (p = 0.007)] had more stimulating home environment. CONCLUSION: Nearly half of the children with CZS who exhibited neurodevelopmental delays lived in homes lacking appropriate sensory stimulation. This study suggests that motor and visual development, including fine and gross motor skills as well as functional vision, may be benefited by the quantity and quality of play and stimulation opportunities available at home.

Longitudinal Change in Physical Activity in Children 6 to 36 Months of Age.

OBJECTIVE: To describe the developmental pattern for physical activity (PA) in children 6-36 months of age and to identify factors that are longitudinally associated with PA as children transition from infancy to preschool age. STUDY DESIGN: The study employed a prospective longitudinal design with baseline data collected when children were approximately 6 months of age. Mothers and infants (n = 124) were recruited through community and educational settings in South Carolina. Data were collected at 6-month intervals from 6 to 36 months. PA was measured via accelerometry. Mothers completed questionnaires that assessed independent variables, including parent characteristics, the child's sex, race, and ethnicity, birth/delivery type, motor milestones, sleep habits, dietary practices, childcare setting, and home environmental factors. Trained research staff administered anthropometric measures and assessed motor developmental status. Growth curve models described the age-related pattern for PA and evaluated relationships between independent variables and change in PA. RESULTS: PA increased by approximately 45% between 6 and 36 months of age and followed a curvilinear pattern, with most of the increase occurring between 6 and 24 months. The child's exposure to television/electronic media was negatively associated with change in PA, and the presence of older siblings in the home was positively associated with change in PA. CONCLUSIONS: As children develop from infancy to early childhood, their PA increases substantially, with most of the increase occurring by 24 months of age.

Does cognitive inhibition contribute to working memory and reasoning during childhood?

Theoretical frameworks suggest that cognitive inhibition suppresses irrelevant information in working memory, preventing overload and promoting the processing of task-relevant information. Consequently, it may also contribute to more complex skills, such as abstract reasoning, by facilitating the retention and processing of patterns and relationships. However, empirical evidence does not consistently show these relationships in early elementary school years. This study aims to examine the validity of the following theoretical proposition: cognitive inhibition is a fundamental process that influences working memory, and both contribute to abstract reasoning in children aged 6-8 years. The final sample included 293 schoolchildren from 1st, 2nd, and 3rd grades, who completed tasks measuring cognitive inhibition, working memory, and reasoning. Age was also considered in the analyses. The main results indicate that age is associated with improvements in working memory and reasoning (explaining 19% of the variance), but not with cognitive inhibition performance. Additionally, cognitive inhibition directly contributes to working memory (explaining 19% of the variance), and working memory, but not cognitive inhibition, contributes to abstract reasoning (the model explains 23% of the variance). No indirect effects were found. We discuss the importance of incorporating specific relationships between cognitive skills at different developmental stages into theoretical and practical proposals.

Early developmental insights into the social construction of race.

The way that societies assign people to racial categories has far-reaching social, economic, and political consequences. One framework for establishing racial boundaries is based on ancestry, which historically has been leveraged to create rigid racial categories, particularly with respect to being categorized as White. A second framework is based on skin tone, which can vary within families and across the lifespan, and is thus more likely to blur racial boundaries. The persistence of these distinct cultural beliefs about race requires that they be transmitted to each new generation, but there have been few cross-cultural studies on their development during childhood. Participants (5- to 12-year-old children, N = 123) were from the United States, in which the ancestry model has been more prevalent, or from Brazil, in which the skin tone model has been more prevalent. In both countries, 5- to 7-year-olds endorsed the belief that skin tone determines race, for example, by assigning biological siblings with differing skin tones to different racial categories. However, racial concepts diverged among the 10- to 12-year-olds, with children from the United States shifting toward a classification based on ancestry and children in Brazil endorsing a classification based on skin tone even more strongly with age. These differing conceptions were especially evident with reference to White racial categorization: Older children from Brazil persisted in classifying lighter skinned people as White when they had African ancestry, unlike older children from the United States. These findings provide important insights into the developmental and cultural influences on racial classification systems. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Regression of microcephaly as a protective factor of neuropsychomotor development in fetal surgery for occipital encephalocele.

PURPOSE: Encephaloceles are neural tube closure defects characterized by herniation of intracranial contents through the skull, with a mortality rate of 33.3%. Approximately 50% of patients who survived have some degree of neuropsychomotor developmental impairment or seizures. This study aimed to analyze the relationship between good neuropsychomotor development (NPMD) in patients undergoing fetal occipital encephalocele correction and the reversal of microcephaly, comparing these outcomes with those observed in patients who underwent postnatal surgery. METHODS: The 22 participants were categorized into two groups: 10 in the fetal group (FG) and 12 in the postnatal group (PNG). During the study, 1 patient was excluded from the FG and 2 patients were excluded from the PNG, totaling 19 patients in the study. All patients were diagnosed, evaluated, and monitored by the same healthcare service between July 2012 and July 2018. All participants were subjected to a careful developmental assessment using the Bayley Scale of Infant Development, Second Edition (BSID-II), up to 2 years and 11 months of age. Additionally, CP measurements were taken during the first year of life to monitor their progress. The relationship between microcephaly reversal and NPMD was studied. RESULTS: The CP adjusted for gestational age showed a tendency toward the reversal of progressive microcephaly after correction of encephaloceles in the FG. We found a statistically significant difference in the median BSID-II score between the PNG and FG. Patients in the FG maintained normal CP development in the first year of life, whereas those in the PNG remained microcephalic. CONCLUSION: The reversal of microcephaly in the FG directly influences good NPMD and can be considered a protective factor.

Risk of alterations in neurodevelopment in infants and preschool children with cancer.

BACKGROUND: Some cancer survivors experience difficulties with concentration, attention, and memory; however, there are no studies on neurodevelopment in patients under 5 years of age who are undergoing cancer treatment. Our aim was to evaluate neurodevelopment in cancer patients under 5 years of age using the Early Development Instrument (EDI) test, considering factors such as nutritional status, type of cancer, and treatment effect. METHODS: A cross-sectional study was conducted from February 2018 to March 2019. Patients with cancer diagnoses outside the central nervous system in any phase of cancer treatment were included. RESULTS: A total of 45 patients were included. Regarding fine motor skills, 28% of patients with retinoblastoma and 23% of patients with leukemia or lymphoma had a risk of developmental delay compared to 0% of patients with solid tumors (p = 0.025). The final results showed that 19 (42.2%) patients had normal neurodevelopment (gray), 7 (15.5%) had a delay in neurodevelopment (light gray), and 19 (42.2%) had a risk of developmental delay (black). Regarding developmental delay, 52% of patients in the leukemia and lymphoma group, 71% in the retinoblastoma group, and 23% in the solid tumor group presented developmental delay (p = 0.06). CONCLUSIONS: The risk of delay and lag in neurodevelopment is common in cancer patients under 5 years of age undergoing treatment. However, more studies are required to evaluate the effect of treatment on this group of patients as it may be affected by various factors.

INTRODUCCIÓN: En algunos pacientes supervivientes de cáncer se presentan dificultades de concentración, atención y memoria, sin embargo no hay estudios en relación al neurodesarrollo en pacientes menores de 5 años que se encuentran en tratamiento oncológico. Por lo que el objetivo fue valorar el neurodesarrollo en pacientes con cáncer durante el tratamiento oncológico mediante la prueba EDI tomando en cuenta diversos factores como su estado nutricional, tipo de cancer, y el efecto del tratamiento. MÉTODOS: Se realizó un estudio transversal, de febrero de 2018 a marzo de 2019. Se incluyeron pacientes mayores de 1 año y menores de 5 años con diagnóstico de cáncer fuera del sistema nervioso central, en tratamiento oncológico. RESULTADOS: Se incluyeron 45 pacientes. En el área motor fina el 28% de los pacientes con retinoblastoma y 23% con leucemias y linfomas se encontraron en rojo (retraso) en comparación con 0% de los pacientes con tumores sólidos (p = 0.025). En el resultado global se encontró que 19 (42.2%) pacientes tuvieron neurodesarrollo normal (gris), 7 (15.5%) rezago en el neurodesarrollo (gris claro) y 19 (42.2%) con riesgo de retraso en el desarrollo (negro). De los pacientes que presentaron riesgo de retraso el 52% fueron del grupo de leucemias y linfomas, el 71% en el grupo de retinoblastoma y el 23% del grupo de tumores sólidos (p = 0.06). CONCLUSIONES: La presencia de riesgo de retraso y rezago en el neurodesarrollo es frecuente en menores de 5 años con diagnóstico de cáncer. Se requieren más estudios, para evaluar el efecto del tratamiento en este grupo de pacientes, ya que pueden influir diversos factores.

Analysis of brain activity for speech stimuli and child development of an infant with neurosyphilis: case report. / Análise da atividade cerebral para estímulos de fala e desenvolvimento infantil de um lactente com neurossífilis: relato de caso.

Neurosyphilis is an infection of the central nervous system caused by Treponema pallidum and may be symptomatic or asymptomatic in children with congenital syphilis. This study aims to describe the cortical activation pattern of a four-month-old infant with neurosyphilis using functional near-infrared spectroscopy (fNIRS). Born at term weighing 3,475 kg, she presented a Venereal Disease Research Laboratory (VDRL) test of 1:32 and changes in the cerebrospinal fluid test. She underwent treatment with crystalline penicillin for 10 days before discharge from the hospital. In the audiological evaluation, she presented normal tympanometry, otoacoustic emissions evoked by transient stimulus, brainstem auditory evoked potential with click stimulus at 80 and 30 dB nHL bilaterally. The Bayley III Scale was applied to assess language, cognition and motor development, showing delays in expressive language and broad motor skills. In the fNIRS acquisition, data were collected through 20 channels divided between the cerebral hemispheres. The /ba/ and /da/ stimuli were presented at 40 dB HL with the Psychopy software through a headphone. Data analysis used the MNE and MNE-NIRS toolboxes in the Spyder environment. The average by channel, ROI, and condition was exported for analysis. A similar theta coefficient was observed between the conditions and channels evaluated in both cerebral hemispheres, with a greater amplitude of oxyhemoglobin (HbO) being observed in the anterior position when compared to the posterior region of the temporal lobe. Therefore, this case report highlights the need to monitor the child development of babies with neurosyphilis.

A neurossífilis é uma infecção do sistema nervoso central causada pelo Treponema pallidum, podendo ser sintomática ou assintomática nas crianças com sífilis congênita. Este estudo visa descrever o padrão de ativação cortical de uma lactente de quatro meses com neurossífilis utilizando o funcional near-infrared spectroscopy (fNIRS). Nascida a termo com 3.475 Kg, apresentou teste Venereal Disease Research Laboratory (VDRL) de 1:32 e alteração no exame de líquor cefalorraquidiano. Realizou tratamento com penicilina cristalina por 10 dias antes da alta hospitalar. Na avaliação audiológica apresentou normalidade na timpanometria, emissões otoacústicas evocadas por estímulo transiente, potencial evocado auditivo de tronco encefálico com estímulo clique a 80 e 30 dB nNA bilateralmente. Foi aplicada a Escala Bayley III para a avaliação do desenvolvimento de linguagem, cognição e motor, apresentando atrasos na linguagem expressiva e no motor amplo. Na aquisição do fNIRS os dados foram coletados por 20 canais divididos entre os hemisférios cerebrais. Os estímulos /ba/ e /da/ foram apresentados a 40 dB NA com o auxílio do programa Psychopy por um fone de ouvido. A análise dos dados utilizou as toolboxes MNE e MNE-NIRS no ambiente Spyder. A média por canal, ROI e condição foi exportada para análise. Observou-se um coeficiente theta similar entre as condições e canais avaliados de ambos os hemisférios cerebrais, sendo observado maior amplitude da oxihemoglobina (HbO) na posição anterior quando comparados a região posterior do lobo temporal. Desta forma, este relato de caso evidencia a necessidade de monitoramento do desenvolvimento infantil de lactentes com neurossífilis.

Assessment and Prognostic Resources for Gross Motor Development in a Child with Cerebral Palsy Related to Congenital Zika Syndrome.

This article describes how the Gross Motor Ability Estimator (GMAE) software can provide important information based on the Gross Motor Function Measure (GMFM)-66 score of a child with congenital Zika syndrome.A child was assessed at 9, 17, and 25 months of age through the GMFM-66. At 2 years, the child's gross motor ability was estimated and classified according to the Gross Motor Function Classification System (GMFCS).At 2 years of age, the child in this case required assistance to roll and was unable to maintain antigravity trunk posture in sitting position, typical abilities of GMFCS level V.GMAE can be useful to guide health professionals that care for children with lifelong physical and developmental care needs. This is the first study that demonstrated how to use the GMAE in this specific population.

Associating neuromotor outcomes at 12 months with wearable sensor measures collected during early infancy in rural Guatemala.

BACKGROUND: Sensitive measures to predict neuromotor outcomes from data collected early in infancy are lacking. Measures derived from the recordings of infant movement using wearable sensors may be a useful new technique. METHODS: We collected full-day leg movement of 41 infants in rural Guatemala across 3 visits between birth and 6 months of age using wearable sensors. Average leg movement rate and fuzzy entropy, a measure to describe the complexity of signals, of the leg movements' peak acceleration time series and the time series itself were derived. We tested the three measures for the predictability of infants' developmental outcome, Bayley Scales of Infant and Toddler Development III motor, language, or cognitive composite score assessed at 12 months of age. We performed quantile regressions with clustered standard errors, accounting for the multiple visits for each infant. RESULTS: Fuzzy entropy was associated with the motor composite score at the 0.5 quantiles; this association was not found for the other two measures. Also, no leg movement characteristic was associated with language or cognitive composite scores. CONCLUSION: We propose that the entropy of leg movement associated peak accelerations calculated from the wearable sensor data collected for a full-day can be considered as one predictor for infants' motor developmental outcome assessed with Bayley Scales of Infant and Toddler Development III at 12 months of age.

Does Catch-Up Growth Come with a Cognitive Cost? Cognitive Outcome and Growth Patterns in Growth Discordant Identical Twins.

OBJECTIVE: To determine whether it is the magnitude of early postnatal catch-up growth (CUG) in response to fetal growth restriction (FGR) or the FGR itself that negatively impacts cognitive outcome in a model of monochorionic twins discordant for fetal growth. STUDY DESIGN: This analysis is part of the LEMON study, a cohort study including all monochorionic twins with selective FGR aged 3 through 17 years. Growth measurements as documented by our primary care system were collected retrospectively. An age-appropriate neurodevelopmental test was performed generating a full-scale IQ (FSIQ). CUG at 2 years was calculated as (weight [kg] at 2 years-birth weight [kg]). We used a multivariable regression model investigating the association between FSIQ (outcome) and birth weight zscore, gestational age at birth and CUG at 2 years (predictors). Generalized estimating equations accounted for the fact that observations between cotwins are not independent. RESULTS: Median age at follow-up of the 46 included twin pairs was 11 (IQR 8-13) years. Birth weight z score and gestational age at birth were significantly associated with FSIQ, with ß-coefficients of 5.897 (95% CI 3.382-8.411), and 2.589 (95% CI 1.227-3.951), respectively (P < .0001). Adjusted for birth weight z score and gestational age, CUG in the first 2 years after birth was not significantly associated with FSIQ (ß-coefficient 0.108 [95% CI -1.373 to 1.590], P = .886). CONCLUSIONS: Our results, combining detailed growth measurements and neurodevelopmental follow-up in a discordant identical twin model, demonstrate that FGR itself rather than early postnatal CUG has negative consequences for cognitive development.

Assessment of newborn neuropsychomotor development born with exposure to SARS-CoV-2 in the perinatal period using the Bayley III scale at 6 months of age.

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.

Trajectory Patterns of Weight and Length in Children: From Birth Until 2-Years of Age.

OBJECTIVE: The aim was to identify trajectory patterns of weight and length in children from birth until two years of life and establish associations with maternal and child characteristics. METHODS: A mixed-cohort study was conducted in public health services in Colombo-PR, Brazil, between 2018 and 2022. Pregnancy information was gathered through anthropometric data collection and questionnaires. Birth data were extracted from birth record forms, while weight and length data in the first two years of life were obtained from physical and electronic health service records. Weight and length trajectory patterns were identified using a group-based trajectory model. The definition of the number of trajectory patterns to be selected considered the model fit to the type of variable, its practical utility, as well as the probabilities of group membership. RESULTS: Two trajectory patterns of weight and length were identified among the children. The majority exhibited a pattern of weight (67.8%, n = 382) and length (90.9%, n = 472) considered high and stable, with a tendency to decelerate from one and a half years of age. The probability of belonging to the lower weight gain group was associated with female sex (41.5%, p < 0.001), smoking during pregnancy (48.7%, p = 0.008), prematurity (65.0%, p = 0.001), cesarean delivery (36.4%, p = 0.009), small for gestational age (69.0%, p < 0.001), and twinning (69.2%, p = 0.002). Similarly, the probability of belonging to the lower length gain group was associated with female sex (11.7%, p < 0.001), smoking during pregnancy (20.6%, p = 0.003), cesarean delivery (10.1%, p = 0.048), born small for gestational age (46.4%, p < 0.001), and twinning (46.1%, p < 0.001). CONCLUSION: Conditions during pregnancy and childbirth can impact growth patterns in the first two years of life.

Parent-Guided Developmental Intervention for Infants With Very Low Birth Weight: A Randomized Clinical Trial.

Importance: Early interventions improve neurodevelopmental outcomes after preterm birth, but few studies of early intervention have focused on preterm infants whose families reside in low- or middle-income countries (LMICs). Objective: To evaluate whether parent-guided early intervention improves the neurodevelopmental outcomes of preterm infants in an LMIC. Design, Setting, and Participants: This randomized clinical trial was performed at a high-risk obstetric referral hospital in Brazil, with outcome evaluations by examiners masked to randomization group. Eligibility criteria were (1) birth at the study hospital, (2) residence within 40 km of the birth hospital, and (3) gestational age of less than 32 weeks or birth weight of less than 1500 g. Of 138 enrolled infants, 19 died after randomization and 19 withdrew from the study; all other enrollees (50 per randomization group) were evaluated for the primary outcome. Data were collected from January 1, 2016, to May 31, 2022, and analyzed from June 10 to July 31, 2022. Interventions: On postnatal day 7, infants were randomized to usual care, consisting of support for lactation, kangaroo care, and routine developmental therapies, or to a parent-guided enhanced developmental intervention, consisting of usual care plus infant massage and enhanced visual stimulation, auditory stimulation, social interactions, and support for motor development, instructed by developmental therapists. Main Outcomes and Measures: The primary outcome was the Bayley Scales of Infant and Toddler Development-Third Edition score at 18 months of age adjusted for prematurity. Results: Among the 100 infants included in the analysis, mean (SD) gestational age was 28.4 (2.2) weeks, and 57 (57%) were male. The mean (SD) gestational age for the intervention group was 28.3 (2.3) weeks; for the usual care group, 28.5 (2.2) weeks. Female infants accounted for 21 infants (42%) of the intervention group and 22 (44%) of the usual care group; male infants, 29 (58%) and 28 (56%), respectively. The enhanced developmental intervention group had higher cognitive scores at 18 months of corrected age (mean [SD], 101.8 [11.9] vs 97.3 [13.5]; mean difference, 4.5 [95% CI, 0.1-8.9]). Conclusions and Relevance: In this randomized clinical trial of a parent-guided developmental intervention for early cognitive function of very preterm or very low birth weight infants implemented in an LMIC, the intervention improved very preterm infants' neurodevelopmental outcomes at 18 months of adjusted age. Parent-guided early intervention can improve neurodevelopmental outcome of very preterm infants born in LMICs. Trial Registration: ClinicalTrials.gov Identifier: NCT02835612.

Analyzing Children's Weight Growth Variations and Associated Factors in Ethiopia, India, Peru, and Vietnam: Using Fractional Polynomial Mixed-Effects Model.

Background: Children's growth is increasingly considered a key mediator of later life outcomes. When examining weight growth, the correlation between repeated observations on the same subject must be regarded as well-modelled. This study aimed to analyze children's weight growth variations and associated factors in Ethiopia, India, Peru, and Vietnam using a fractional polynomial mixed-effects model. Methods: This study used longitudinal data from the Young Lives Cohort Study conducted from 2002 to 2016 in Ethiopia, India, Peru, and Vietnam. The study included 7,140 children of 1 to 15 years old A fractional polynomial mixed-effects model was used to analyze the data. Results: Ethiopian, Peruvian, and Vietnamese children had significantly higher average body weights than children in India (1.426, P<0.001; 1.992, P<0.001; 1.334, P<0.001, respectively). Girl children's average body weight was significantly 0.15 times less than that of boys (-0.148; P=0.027). The average weight of rural children was significantly 0.671 times less than that of urban children (0.671, P<0.001). Children from Peru and Vietnam had higher rates of weight change than those from India. However, the rate of weight change was lower in Ethiopian children than in Indian children. Children from urban areas had a significantly higher rate of weight gain than those from rural areas. Conclusion: Country, sex, residence, parental education, household size, wealth, good drinking water, and reliable power affected children's longitudinal weight growth. Therefore, WHO and the nation's health ministry should monitor children's weight growth status and these associated factors to plan future action.

Growth and Cognitive Development in Tanzanian Children are Associated with Timing of Birth in Relation to Seasonal Malnutrition.

OBJECTIVE: To evaluate in a rural Tanzanian birth cohort the association between birth timing in relation to the preharvest lean season and early-life growth and cognitive development. STUDY DESIGN: Children were enrolled within 14 days of birth and followed up for 18 months. Child anthropometry was measured every 3 months. The Malawi Developmental Assessment Test was administered at the end of follow-up. We estimated the association between timing of birth in the context of other early childhood risk factors and both growth and Malawi Developmental Assessment Test scores. RESULTS: Children born in the preharvest months September and October had the lowest cognitive scores at 18 months, compared with birth in July and August (-1.05 change in overall Malawi Developmental Assessment Test development-for-age Z score, 95% CI: -1.23, -0.86). This association was observed for the language (-1.67 change in development-for-age Z score; 95% CI: -1.93, -1.40) and fine motor subcomponent scores (-1.67; 95% CI: -1.96, -1.38) but not for gross motor (-0.07; 95% CI: -0.23, 0.10) or social subcomponents (-0.07; 95% CI: -0.23, 0.10). Children born in September and October were the longest at birth but had the largest declines in growth Z scores during the first 6 months. CONCLUSIONS: There was a strong association between birth at the beginning of the preharvest season and poor growth and cognitive development. If these associations were mediated by the preharvest postnatal environment, targeted maternal and child interventions for children born during high-risk periods may improve these outcomes. TRIAL REGISTRATION: NCT03268902 (https://clinicaltrials.gov/study/NCT03268902).

Inpatient Skin-to-skin Care Predicts 12-Month Neurodevelopmental Outcomes in Very Preterm Infants.

OBJECTIVE: To examine the relationship between inpatient skin-to-skin care rates and neurodevelopmental scores measured at 12 months in very preterm (VPT) infants. STUDY DESIGN: From a retrospective review of medical records of 181 VPT infants (<32 weeks gestational age [GA] at birth), we derived skin-to-skin care rate, ie, total minutes of skin-to-skin care each infant received over the number of days of hospital stay. We used scores on the Capute Scales from routine follow-up assessments at 12 months to measure neurodevelopmental outcomes. RESULTS: Families averaged approximately 17 minutes/day of skin-to-skin care (2 days/week, 70 minutes/session), although there was substantial variability. Variation in skin-to-skin rate was positively associated with outcomes at 12 months corrected age (r = 0.25, P < .001). Skin-to-skin rate significantly predicted 6.2% unique variance in 12-month neurodevelopmental outcomes, after adjusting for GA, socioeconomic status (SES), health acuity, and visitation frequency. A 20-minute increase in skin-to-skin care per day was associated with a 10-point increase (0.67 SDs) in neurodevelopmental outcomes at 12 months. GA and infant health acuity did not moderate these relations. CONCLUSION: VPT infants who experienced more skin-to-skin care during hospitalization demonstrated higher scores on 12-month neurodevelopmental assessments. Results provide evidence that skin-to-skin care confers extended benefits to VPT infants through the first year of life. Skin-to-skin care offers promise as a family-centered intervention designed to promote positive developmental outcomes in at-risk infants.

Neuromotor Behavior of Infants at 3 and 6 Months Prenatally Exposed to SARS-CoV-2: a Brief Report.

Prenatal SARS-CoV-2 infection may be a risk factor for neurological impairment. This study describes the neuromotor behavior of infants prenatally exposed to SARS-CoV-2 using gold standard tools for early detection of neurological impairment. Sixteen infants were included in this exploratory longitudinal study. Infants were assessed at 3 months using the Prechtl General Movement Assessment, and at 6 months using the Hammersmith Infant Neurological Examination. Infants might have presented neuromotor limitations at 3 months; however, they progressed to a low-risk outcome of neurological impairment at 6 months.

Context of digital media use in early childhood: Factors associated with cognitive development up to 36 months of age.

The influence of digital media on child cognitive development is a complex factor that goes beyond screen time. This study investigates the broader impact of digital media on child cognitive development, considering contextual variables such content type, parental mediation, and maternal mental health. Brazilian mothers (N = 212) of children 4-36 months old answered an online survey. Results showed that children's screen time increases with age. The model with unmediated use, non-educational content, and mother's screen time explains 28.7 % of children's screen time variance. Non-educational content and simultaneous screen media use explained 5.3 % of the variance in toddlers' cognitive development. Mothers with common mental disorders tended not to mediate their children's media use. We discuss the influence of caregivers' availability to mediate infants' and toddlers' digital media use and its impact on children's cognitive development. These findings underscore the necessity for educational and awareness campaigns aimed at fostering access to high-quality digital content for children during critical stages of development.
