Ying Z, Karshaleva B, Deák G. Infant sensorimotor decoupling from 4 to 9 months of age: Individual differences and contingencies with maternal actions. Infant Behav Dev 2024; 76:101957. [PMID: 38823341 DOI: 10.1016/j.infbeh.2024.101957] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 04/29/2024] [Accepted: 05/08/2024] [Indexed: 06/03/2024]
Abstract
Triadic interactions, wherein infants coordinate attention between caregivers and objects of shared focus, are believed to facilitate infant learning, and emerge around 9-12 months of age (Carpenter et al., 1998). Sensorimotor decoupling, wherein infants look at one percept while manipulating another, or use each hand for different actions, was hypothesized (de Barbaro et al., 2016) to contribute to triadic skills by allowing infants to smoothly shift attention between objects and social partners. We explored the development of Hand-Hand (H-H) and Gaze-Hand (G-H) decoupling in 38 infants at 4, 6, and 9 months. We also tested contingencies between maternal behaviors and infant decoupling: i.e., whether decoupling events followed maternal object-directed actions. Both overall and contingent infant decoupling increased from 4 to 9 months. Decoupling rates (both G-H and H-H) predicted variance in infants' fine and gross motor scores. Contingent G-H decoupling at 6 months predicted BSID-III communication scores at 18 months. Thus the development of infant sensorimotor skills, including decoupling, allows infants to smoothly shift attention and participate in triadic interactions.

Neurodevelopmental outcomes of preterm infants after randomisation to initial resuscitation with lower (FiO 2 <0.3) or higher (FiO 2 >0.6) initial oxygen levels. An individual patient meta-analysis. Arch Dis Child Fetal Neonatal Ed 2022; 107:386-392.

Abstract
OBJECTIVE To determine the effects of lower (≤0.3) versus higher (≥0.6) initial fractional inspired oxygen (FiO2) for resuscitation on death and/or neurodevelopmental impairment (NDI) in infants <32 weeks' gestation. DESIGN Meta-analysis of individual patient data from three randomised controlled trials. SETTING Neonatal intensive care units. PATIENTS 543 children <32 weeks' gestation. INTERVENTION Randomisation at birth to resuscitation with lower (≤0.3) or higher (≥0.6) initial FiO2. OUTCOME MEASURES Primary: death and/or NDI at 2 years of age.Secondary: post-hoc non-randomised observational analysis of death/NDI according to 5-minute oxygen saturation (SpO2) below or at/above 80%. RESULTS By 2 years of age, 46 of 543 (10%) children had died. Of the 497 survivors, 84 (17%) were lost to follow-up. Bayley Scale of Infant Development (third edition) assessments were conducted on 377 children. Initial FiO2 was not associated with difference in death and/or disability (difference (95% CI) -0.2%, -7% to 7%, p=0.96) or with cognitive scores <85 (2%, -5% to 9%, p=0.5). Five-minute SpO2 >80% was associated with decreased disability/death (14%, 7% to 21%) and cognitive scores >85 (10%, 3% to 18%, p=0.01). Multinomial regression analysis noted decreased death with 5-minute SpO2 ≥80% (odds (95% CI) 09.62, 0.98 to 0.96) and gestation (0.52, 0.41 to 0.65), relative to children without death or NDI. CONCLUSION Initial FiO2 was not associated with difference in risk of disability/death at 2 years in infants <32 weeks' gestation but CIs were wide. Substantial benefit or harm cannot be excluded. Larger randomised studies accounting for patient differences, for example, gestation and gender are urgently needed.

Abstract
OBJECTIVE An understanding of the trajectory and norm of development in children is needed in order to understand the concept of the spectrum in the diagnosis of autism spectrum disorder (ASD). Children's developmental growth trajectory was measured from six to 66 months in the Taiwan Birth Cohort Study dataset (N = 11,145). Additionally, over 4 years of follow-up, the negative predictive value of using the Parental Concern Checklist and Taiwan Birth Cohort Study Developmental Instrument was also investigated as the first stage of screening in a two-stage window screening method for ASD diagnosis. RESULTS The growth trajectory showed that children's language development began to increase at 18 months, and peaked at 36 months. On the other hand, social development showed steady growth from 18 to 66 months. The increase in the trajectory of children's language development prior to age three, when compared with other developmental dimensions, may increase the difficulty of diagnosing ASD. The two-stage window screening method can be used in settings where the screening sample is large, such as in community or primary care settings, and has been found to be time- and cost-efficient. Better understanding of children's developmental trajectory can enhance detection and intervention for ASD.

Abstract
OBJECTIVES To investigate whether the serotonin transporter (5-HTT or SERT or SLC6A4) mRNA level could be used as a biomarker of treatment response in patients with major depression treated with different antidepressants while controlling related factors. METHODS One hundred and nineteen patients with major depression were recruited; all genotyped for the 5-HTT polymorphism concerning 5-HTTLPR, rs25531, and STin2 VNTR, provided demographic data and completed relevant questionnaires. Duloxetine and paroxetine were administered over 32 weeks to these patients. The Hamilton depression rating scale (HDRS) and 5-HTT mRNA level were evaluated at baseline (Week 0), and at 8, 16, 24 and 32 weeks. RESULTS Improvement in depressive symptoms (HDRS score declined) and increasing in 5-HTT mRNA level were found with longer duration of antidepressant treatment in patients with major depression. Patients with more 5-HTTPR long-form alleles and STin2.12 alleles had poor antidepressant treatment response. Duloxetine may give a better treatment response than paroxetine. Using structural equation modeling (SEM), the 5-HTTLPR long-form had a direct positive association with the 5-HTT mRNA level and an indirect adverse relationship with the 5-HTT mRNA level through neuroticism and previous suicide attempts. CONCLUSION The 5-HTT mRNA level increased and correlated with the treatment response (HDRS score improvement) under 32-weeks antidepressants treatment clinical trial. We speculate that the 5-HTT mRNA level may be used as a potential biomarker of antidepressant treatment response.

Pediatr Neonatol 2018; 59:168-175.

Abstract
BACKGROUND For infants with very low birth weights (VLBW), their neurodevelopmental outcomes are thought to be associated with extra-uterine growth retardation (EUGR). In this study, based on a single institute, we analyzed the association between different levels or severity of EUGR of VLBW infants and their neurodevelopmental outcomes later at a corrected age of 24 months. METHODS This is a hospital-based retrospective cohort study. The severity of EUGR was classified into three categories according to the z-score of discharge weight: z < -2.0, <-2.5, and <-3.0. The outcomes were assessed using the Bayley Scales of Infant Development-II (BSID-II) at a corrected age of 24 months. We then estimated the association of EUGR with low mental developmental index (MDI) or low psychomotor developmental index (PDI). Multiple logistic regression and stratified analyses were used to adjust for the possible confounding factors. RESULTS In total, 224 VLBW infants were enrolled in this study from 1997 to 2006. In the univariate analysis, EUGR for weight at discharge from hospital was associated with MDI <85 at the corrected age of 24 months, and this association was related to the severity of EUGR (z < -2.5, OR: 1.92 (1.04-3.53); z < -3.0, OR: 2.83 (1.26-6.36)). In addition, the relationship was not confounded by gender nor small for gestational age. The stratified analysis against hemodynamic significant patent ductus arteriosus also revealed that EUGR was an independent predictor for neurodevelopmental outcomes. CONCLUSION In VLBW preterm infants, EUGR was significantly associated with low MDI scores assessed at a corrected age of 24 months. Early evaluation and recognition of EUGR should be emphasized when caring for preterm infants.

Abstract
The objective of this study was to investigate stability of cognitive development during the first five years of life in relation to heavy metal concentrations in umbilical cord blood in Korean children. This research is part of the Mothers' and Children's Environmental Health (MOCEH) study, a multi-center prospective birth cohort study of pregnant women in Korea who were recruited from 2006 to 2010. We analyzed the complete follow-up data of children who were 5years-old in 2016. We measured lead, mercury, and cadmium levels in the umbilical cord blood of 251 children, and analyzed them, for whom neurodevelopmental data were available. We determined stability of cognitive development scores using three methods. First, we used partial correlation analyses to examine the stability of cognitive development at each measurement time. Second, we used Cramer's V to investigate the magnitude and direction of changes in cognitive development scores at each follow-up period among three groups (high, medium, and low scores). The results showed that cognitive development scores measured at the closest times had the strongest correlations, and the stability of cognitive development scores increased with age, from 6 to 60months. Groups at the extreme ends of cognitive development (high or low scores) had more stable scores, and this tendency was also stronger in infants >24months-old. The stability of cognitive development was unrelated to the umbilical cord level of heavy metals, based on analysis with Fisher's transformation. In conclusion, the present study showed that the cognitive development scores in a cohort of infants (6 to 60months-old) were stable.

Abstract
Infants born preterm have increased risk for learning disabilities yet we lack assessments to successfully detect these disabilities in early life. We followed 23 full-term and 29 preterm infants from birth through 24 months to assess for differences in and stability of learning abilities across time. Measures included the Bayley-III cognitive subscale, the mobile paradigm assessment, and a means-end learning assessment. Preterm infants had poorer performance on measures of cognition and learning across the first two years of life. Learning performance at 3-4 months was consistent with learning performance at 12-24 months of age. At 3-4 months, the mobile paradigm had better sensitivity and predictive values for predicting 24-month cognitive delays on the Bayley-III than did the Bayley-III itself. At 12-18 months, the means-end learning assessment had better sensitivity than the Bayley-III for identifying 24-month cognitive delays on the Bayley-III. The results suggest that: (1) infants born preterm may demonstrate learning differences as early as the first few months of life, (2) learning differences identified in the first months of life are likely to persist throughout the second year of life, and (3) learning assessments that measure how infants and toddlers use their typical behaviors to problem-solve to control external events may be more effective than traditional standardized assessment tools for detecting early learning delays.
