Parent-child interaction related to brain functional alterations and development outcomes in autism spectrum disorder: A study based on resting state-fMRI

BACKGROUND

Limited study has investigated the influence of parent-child interaction on brain functional alterations and development outcomes of autism spectrum disorder (ASD) children. This pilot study aimed to explore the relationship between parent-child interaction, brain functional activities and development outcomes of ASD children.

METHODS

and Procedures: 653 ASD with an average age of 41.06 ± 10.88 months and 102 typically developmental (TD) children with an average age of 44.35 ± 18.39 months were enrolled in this study, of whom 155 ASD completed brain rs-fMRI scans. The amplitude of low-frequency fluctuations (ALFF) and regional homogeneity (ReHo) measured using resting-state functional magnetic resonance imaging (rs-fMRI) data reflect local brain function. The parent-child interaction was assessed by the Chinese Parent-child Interaction Scale (CPCIS). Childhood Autism Rating Scale (CARS) and developmental quotient (DQ) indicated development outcomes.

OUTCOMES AND RESULTS

Total CPCIS score was negatively correlated with CARS total score, and positively correlated with DQ. The frequency of parent-child interaction was negatively correlated with ALFF values in the left median cingulate and paracingulate gyri (DCG.L) and ReHo values in the right superior frontal gyrus, medial (SFGmed.R)(P < 0.05, FDR correction). ALFF values in the DCG.L and ReHo values in the SFGmed.R play complete mediating roles in the relationship between parent-child interaction and performance DQ.

CONCLUSION AND IMPLICATIONS

This study suggest that parent-child interaction has an impact on autistic characteristics and DQ of ASD children. Local brain regions with functional abnormalities in the DCG.L and SFGmed.R may be a crucial factors affecting the performance development of ASD children with reduced parent-child interaction.

Comparison of Neurodevelopmental Status in Early Infancy of Infants of Women With and Without Gestational Diabetes Mellitus

OBJECTIVES

To study the neurodevelopmental status of offsprings of mothers with gestational diabetes (OGDM) aged 3½ mo.

METHODS

This cross-sectional study was conducted at a tertiary hospital, New Delhi which included infants aged 3½ mo (+1 wk) who were either offsprings of women with gestational diabetes (cases) or infants of mothers without gestational diabetes mellitus presenting to tertiary care public hospital in India from January, 2018 through March, 2019, with enrollment of infants done between 10 April, 2018 and 30 March, 2019.

RESULTS

The development quotient (DQ) using Developmental Assessment Scales for Indian Infants (DASII) was calculated as Motor DQ, Mental DQ and a composite DQ. The mean motor DQ of the enrolled infants was 101.7 (12.02); it was significantly lower for OGDM than controls [101 (1.41) vs. 109.5 (10.6); P <0.001]. The mean mental DQ of the enrolled infants was 88.9 (12.0); it was significantly lower for OGDM than the control group [84 (9.89 vs. 88 (8.48); P = 0.03]. The total development quotient for the enrolled infants was 95.3 (11.3). The total development quotient for study group was significantly lower than the control group [92.5 (5.65) vs. 98.75 (9.54); P = 0.001].

CONCLUSIONS

The mean motor, mental total DQ of offsprings of mothers with GDM were significantly lower than those born to mothers without GDM. Hence follow up, early intervention should be considered for this high risk group.

Maternal folic acid supplement use/dietary folate intake from preconception to early pregnancy and neurodevelopment in 2-year-old offspring: the Japan Environment and Children's Study

We evaluated the association between maternal prenatal folic acid supplementation/dietary folate intake and motor and cognitive development in 2-year-old offspring using data from the Japan Environment and Children's Study database. Neurodevelopment of 2-year-old offspring were evaluated using the Kyoto Scale of Psychological Development 2001. In total, data of 3839 offspring were analysed. For folic acid supplementation, a multiple regression analysis showed that offspring of mothers who started using folic acid supplements before conception had a significantly lower developmental quotient (DQ) in the postural-motor DQ area than offspring of mothers who did not use them at any time throughout their pregnancy (partial regression coefficient (B) -2·596, 95 % CI -4·738, -0·455). Regarding daily dietary folate intake from preconception to early pregnancy, a multiple regression analysis showed that the group with ≥ 200 µg had a significantly higher DQ in the language-social area than the group with <200 µg. The DQ was higher in the ≥ 400 µg group (B 2·532, 95 % CI 0·201, 4·863) than the 200 to <400 µg group (B 1·437, 95 % CI 0·215, 2·660). In conclusion, our study showed that maternal adequate dietary folate intake from preconception to early pregnancy has a beneficial association with verbal cognition development in 2-year-old offspring. On the other hand, mothers who started using folic acid supplements before conception had an inverse association with motor development in 2-year-old offspring. There were no details on the amount of folic acid in the supplements used and frequency of use. Therefore, further studies are required.

Comparison of psychomotor development among children conceived through icsi in-vitro-fertilisation and naturally at 5 through 30 months of age, Vietnam

OBJECTIVE(S)

To compare psychomotor development during 5 months to 30 months of age among children who were conceived via ICSI in-vitro fertilization to those conceived naturally.

STUDY DESIGN

Prospective cohort study was conducted during 2017-2018 with children visiting Tu Du Hospital for scheduled health checks. We randomly recruited 935 five-to-thirty-month-old children and distributed them into two groups for comparison: a group of 426 ICSI/IVF children and a group of 509 Naturally Conceived (NC) children. A team of pediatric mental health professionals used the revised Brunet-Lézine scale to directly examine those children and assess their Developmental Quotient (DQ). Controlling confounders with Propensity Score Matching (PSM), we analyzed and compared psychomotor development in 421 IVF children conceived by intracytoplasmic sperm injection (ICSI) against 421 NC.

RESULT(S)

At DQ cut-off point of 85, study data pinpointed no difference in such single DQs as motor posture, sociability and global scores between the two cohort groups. However, there was a difference in coordination and language DQs. IVF group's low-score proportion for coordination was 2.16 times that of NC group [95 % CI: 1.11-4.21] and its low-score proportion for language was 2.15 times that of NC group [95 % CI: 1.15-4.01].

CONCLUSION

This study showed that IVF was not completely free from adverse effects. At the age of five to thirty months, IVF children would develop language and motor coordination more slowly than NC children, suggesting IVF should be done only when needed.

Study on serum Tau protein level and neurodevelopmental outcome of placental abruption with neonatal hypoxic-ischemic encephalopathy

Objective: The aim of this study was to explore differences in serum Tau protein levels and neurodevelopmental prognoses of placental abruption or umbilical cord around neck with hypoxic-ischemic encephalopathy (HIE).Methods: Forty neonates with moderate/severe HIE divided into placental abruption with HIE group (placental abruption with hypoxic-ischemic encephalopathy (PA-HIE) group) (n = 18) and umbilical cord around the neck with HIE group (umbilical cord around the neck with hypoxic-ischemic encephalopathy (UCAN-HIE) group) (n = 22). Healthy term newborns comprised the control group (n = 35). Serum Tau protein levels were measured using an enzyme-linked immunosorbent assay 24 hours (3.50 hours [1.00-24.00]) after birth. Neurodevelopment outcomes were assessed based on the Gesell Developmental Scale at 9 months of age.Results: Serum Tau protein levels were significantly higher in 40 cases (1013 pg/ml [538.04-1190.42]) than in the control group (106.41 pg/ml [64.55-154.71], p = .0001). Serum Tau protein levels in the PA-HIE group (1024.46 pg/ml [657.88-1190.42]) were significantly higher than those in the UCAN-HIE group (892.78 pg/ml [538.04-1179.50], p = .0149). The development quotient score in the PA-HIE group (67.0 [47.0-90.0]) was significantly lower than that in the UCAN-HIE group (81.5 [52.6-100.0]) (p = .0028). The component ratio of neurodevelopmental retardation in the PA-HIE group (44.45%) was significantly higher than that in the UCAN-HIE group (22.73%) (X² = 13.3138, p = .0013).Conclusions: Compared with the UCAN-HIE group, the serum Tau protein level and the component ratio of neurodevelopmental retardation were significantly higher in the PA-HIE group.

Prediction of poor neurological development in patients with symptomatic congenital cytomegalovirus diseases after oral valganciclovir treatment

OBJECTIVE

This study aimed to evaluate the neurodevelopmental outcomes of infants with symptomatic congenital cytomegalovirus (SCCMV) disease after antiviral treatment and investigate the symptoms at birth associated with a developmental quotient (DQ) < 70.

METHODS

In this prospective study conducted from 2009 to 2018, infants with SCCMV disease who received oral valganciclovir (VGCV; 32 mg/kg/day) for 6 weeks (November 2009 to June 2015) or 6 months (July 2015 to March 2018) were evaluated for their neurodevelopmental outcomes at around 18 months of corrected age. Sequelae were categorized as follows: no impairment with a DQ ≥ 80 and no hearing dysfunction; mild sequelae including unilateral hearing dysfunction or a DQ of 70-79; and severe sequelae with a DQ < 70, bilateral hearing dysfunction requiring hearing aids, blindness or epilepsy requiring anti-epileptic drugs. DQ was assessed using the Kyoto Scale of Psychological Development. Symptoms at birth associated with a DQ < 70 were determined using univariate and receiver operating characteristic curve analyses.

RESULTS

Of the 24 treated infants, 21 reached > 18 months of corrected age. Six (29%) were no impairment, 4 (19%) had mild sequelae, and 11 (52%) developed severe sequelae. The symptoms at birth associated with a DQ < 70 were microcephaly and/or small for gestational age.

CONCLUSION

In our cohort of infants with SCCMV disease after VGCV treatment, the incidence of severe sequelae at 18 months of corrected age was around 50%. When microcephaly and/or small for gestational age are seen at birth, a low DQ may appear even after oral VGCV treatment.

Beneath the floor: re-analysis of neurodevelopmental outcomes in untreated Hurler syndrome

Background

Hurler syndrome (MPS IH), the severe, neurodegenerative form of type one mucopolysaccharidosis, is associated with rapid neurocognitive decline during toddlerhood and multi-system dysfunction. It is now standardly treated with hematopoietic cell transplantation (HCT), which halts accumulating disease pathology and prevents early death. While norm-based data on developmental functioning in untreated children have previously demonstrated neurocognitive decline, advances in methodology for understanding the cognitive functioning of children with neurodegenerative diseases have highlighted that the previous choice of scores to report results was not ideal. Specifically, the lowest possible norm-based score is 50, which obscures the complete range of cognitive functioning at more advanced stages of neurodeterioration. To a set of cognitive data collected on a sample of untreated children, we applied a modern method of score analysis, calculating a developmental quotient based on age equivalent scores, to reveal the full range of cognitive functioning beneath this cutoff of 50, uncovering new information about the rapidity of decline and the profound impairment in these children.

Results

Among 39 observations for 32 patients with untreated Hurler syndrome, the full array of cognitive functioning below 50 includes many children in the severely to profoundly impaired range. The loss of skills per time unit was 14 points between age 1 and 2. There was a very large range of developmental quotients corresponding to the norm-based cutoff of 50.

Conclusions

This report enables clarification of functioning at levels that extend beneath the floor of 50 in previous work. At the dawn of newborn screening and amidst a proliferation of new therapies for MPS I, these data can provide crucial benchmark information for developing treatments, particularly for areas of the world where transplant may not be available.

Surgical versus medical treatment for children with epileptic encephalopathy in infancy and early childhood: Results of an international multicenter cohort study in Far-East Asia (the FACE study)

OBJECTIVE

To compare the seizure and developmental outcomes in infants and young children with epileptic encephalopathy who have undergone surgical and medical treatments.

METHODS

An international, multicenter, observational cohort study was undertaken. A total of 317 children aged <6 years, who had frequent disabling seizures despite intensive medical treatments, were registered. Among the enrolled children, 250 were treated medically (medical group), 31 underwent resective surgery (resective group), and 36 underwent palliative surgery [callosotomy (n=30) or vagal nerve stimulation (n=6); palliative group] on admission. Seizure and developmental outcomes were obtained for 230 children during the 3-year follow-up period. Cox proportional hazard model was used to adjust for clinical backgrounds among treatment groups when comparing the seizure-free survival rates.

RESULTS

At the 3-year follow-up, seizure-free survival was 15.7%, 32.1%, and 52.4% in the medical, palliative, and resective groups, respectively. The adjusted hazard ratios for seizure recurrence in the resective and palliative groups versus the medical group were 0.43 (95% CI, 0.21-0.87, P=0.019) and 0.82 (95% CI, 0.46-1.46, P=0.50), respectively; the former was statistically significant. Regarding the developmental outcome, the mean DQs in the resective group increased significantly compared to those in the medical group during the follow-up (P<0.01). As for subgroup analysis, better seizure and development outcomes were demonstrated in the resective group compared to the medical group in children with nonsyndromic epilepsies (those to which no known epilepsy syndromes were applicable).

SIGNIFICANCE

These results suggest that surgical treatments, particularly resective surgeries, are associated with better seizure and developmental outcomes compared with successive medical treatment. The present observations may facilitate the identification of infants and young children with epileptic encephalopathy who could benefit from surgery.

Developmental assessment of VLBW infants at 18 months of age: A comparison study between KSPD and Bayley III

AIM

To assess the developmental characteristics of very low-birth-weight (VLBW) infants using the Kyoto Scale of Psychological Development (KSPD) and to compare with those using the Bayley Scales, third edition (Bayley III).

METHODS

KSPD and Bayley III were performed on 124 Japanese VLBW infants at 18months of corrected age at a 2-week interval by trained psychologists. The relationships between KSPD and Bayley III in corresponding pairs: Cognitive-Adaptive (C-A) developmental quotient (DQ) and cognitive composite (Cog) scores, Language-Social (L-S) DQ and language composite (Lang) scores, and Postural-Motor (P-M) DQ and motor composite (Mot) scores were analyzed.

RESULTS

The means [SD] of C-A DQ, L-S DQ, P-M DQ, and overall DQ of KSPD were 94 [15], 90 [17], 89 [15], and 93 [14], respectively. The means [SD] of the Cog, Lang, and Mot scores of Bayley III were 96 [13], 84 [12], and 91 [12], respectively. The DQ of KSPD strongly correlated with the corresponding composite score of Bayley III; Spearman rank correlations between the Cog score and C-A DQ, the Lang score and L-S DQ, and the Mot score and P-M DQ were 0.65, 0.71 and 0.55, respectively. The selected cut-off of the Cog score of <85 accurately identified development delay, defined by KSPD, with sensitivity of 100% and specificity of 85%.

CONCLUSION

Although absolute value of the Bayley III score may not represent the degree of impairment, the developmental characteristics on KSPD well correlated with those on Bayley III. The developmental outcomes of Japanese VLBW infants were verified by the two tests.

Extremely preterm infants small for gestational age are at risk for motor impairment at 3 years corrected age

BACKGROUND

Few studies have targeted psychomotor development and associated perinatal risk factors in Japanese very low birth weight (VLBW) infants who are severely small for gestational age (SGA).

DESIGN/SUBJECTS

A single-center study was conducted in 104 Japanese VLBW infants who were born preterm, due to maternal, umbilical cord, or placental abnormalities, between 2000 and 2007. Psychomotor development as a developmental quotient (DQ) was assessed using the Kyoto Scale of Psychological Development at 3 years corrected age. Severely SGA was defined as birth weight or length below -2 standard deviation values of the mean values at the same gestation. VLBW infants were divided into 2 subgroups based on gestational age at birth: ⩾28 weeks (n=64) and <28 weeks (n=40). DQs of infants with severe SGA were compared with those of infants who were appropriate for gestational age (AGA). Factors associated with developmental disabilities in VLBW infants with severe SGA (n=23) were determined.

RESULTS

In the group born at ⩾28 weeks gestation, infants with severe SGA had normal DQ values and did not significantly differ from those with AGA. However, in the group born at <28 weeks gestation, severe SGA infants had significantly lower postural-motor DQ values than AGA infants. Gestational age <28 weeks was an independent factor for low postural-motor DQ, regardless of the cause of severe SGA or pregnancy termination.

CONCLUSIONS

Extremely preterm newborns with severe SGA are at risk of motor developmental disability at age 3 years.

Concurrent validity of the differential ability scales, second edition with the Mullen Scales of Early Learning in young children with and without neurodevelopmental disorders

Estimates of intelligence in young children with neurodevelopmental disorders are critical for making diagnoses, in characterizing symptoms of disorders, and in predicting future outcomes. The limitations of standardized testing for children with developmental delay or cognitive impairment are well known: Tests do not exist that provide developmentally appropriate material along with norms that extend to the lower reaches of ability. Two commonly used and interchanged instruments are the Mullen Scales of Early Learning (MSEL), a test of developmental level, and the Differential Ability Scales, second edition (DAS-II), a more traditional cognitive test. We evaluated the correspondence of contemporaneous MSEL and the DAS-II scores in a mixed sample of children aged 2-10 years with autism spectrum disorder (ASD), non-ASD developmental delays, and typically developing children across the full spectrum of cognitive ability. Consistent with published data on the original DAS and the MSEL, scores on the DAS-II and MSEL were highly correlated. However, curve estimation revealed large mean differences that varied as a function of the child's cognitive ability level. We conclude that interchanging MSEL and DAS-II scores without regard to the discrepancy in scores may produce misleading results in both cross-sectional and longitudinal studies of children with and without ASD, and, thus, this practice should be implemented with caution.

Immediate spontaneous shape correction using expantile zigzag craniectomy in infantile scaphocephaly -is there an improvement in the developmental quotient following surgery?-

There is still debate over which method of the surgery is the most appropriate for the treatment of scaphocephalic infants. In addition, change in psychomotor development following these procedures is a very complex issue that has not yet been resolved. In this paper, the authors describe a surgical technique for immediate spontaneous shape correction of infantile scaphocephaly. There were significant differences between pre- and postoperative cephalic index. We also describe an improvement in the developmental quotient following surgery. Therefore, this expantile zigzag craniectomy should be recommended to correct for isolated sagittal craniosynostosis in infants.
