Both exposures have been associated with increased risk of ASD in previous studies, but potential synergistic effects remain underexplored. We conducted a population-based cohort study of singleton children born at term gestation (37-41 weeks) in New South Wales, Australia from January 2002 to December 2008. Maternal autoimmune diagnoses and childhood infections before age 2 years were identified from linked maternal and child hospital admissions, and ASD diagnoses by age 9 years were identified from linked disability services data. Multivariable logistic regression assessed the association between each exposure and ASD and additive interaction between exposures, controlling for potential confounders. A total of 18,451 children exposed to maternal autoimmune disease were propensity score matched (1:2) to 36,902 unexposed children. Any maternal autoimmune disease (adjusted odds ratio (aOR) 1.25, 95% confidence interval (CI) 1.07-1.47) and any childhood infection before age 2 years (aOR 1.38, 95% CI 1.15-1.67) were each associated with ASD. However, there was no evidence of additive interaction between the two exposures (relative excess risk due to interaction [RERI] 0.128, 95% CI -0.418-0.675) resulting in increased odds of ASD in offspring. Future studies could examine potential interactions between other sources of maternal immune activation and childhood infection and impact on ASD and other neurodevelopmental disorders.

Clinical characteristics and long-term neurodevelopmental outcomes of leukomalacia in preterm infants and term infants: a cohort study / Juan SONG in Journal of Neurodevelopmental Disorders, 15 (2023)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 15 (2023) Titre : Clinical characteristics and long-term neurodevelopmental outcomes of leukomalacia in preterm infants and term infants: a cohort study Type de document : texte imprimé Auteurs : Juan SONG, Auteur ; Yuyang YUE, Auteur ; Huiqing SUN, Auteur ; Ping CHENG, Auteur ; Falin XU, Auteur ; Bingbing LI, Auteur ; Kenan LI, Auteur ; Changlian ZHU, Auteur Langues : Anglais (eng) Mots-clés : Infant, Newborn  Infant  Humans  Child, Preschool  Child  Infant, Premature  Cohort Studies  Leukomalacia, Periventricular/complications/epidemiology/diagnosis  Cerebral Palsy/diagnosis/pathology  Epilepsy  Cerebral palsy  Head MRI  Leukomalacia  Neurodevelopmental outcomes  Newborn Index. décimale : PER Périodiques Résumé : BACKGROUND: Leukomalacia is a serious form of neonatal brain injury that often leads to neurodevelopmental impairment, and studies on neonatal leukomalacia and its long-term outcomes are lacking. The aim of this study was to analyze the clinical manifestations, imaging features, and long-term neurodevelopmental outcomes in preterm infants and term infants with leukomalacia. METHODS: Newborns diagnosed with leukomalacia by head magnetic resonance imaging (MRI) and who were admitted to intensive care units from January 2015 to June 2020 were enrolled. All infants were followed up to June 2022 (2-7 years old), and their neurodevelopmental outcomes were evaluated. The clinical data and long- term outcomes of preterm infants and term infants was analyzed by Chi-square tests. RESULTS: A total of 218 surviving infants with leukomalacia including 114 preterm infants and 104 term infants completed the follow-up. The major typesof leukomalacia on MRI were periventricular leukomalacia in the preterm group and subcortical cystic leukomalacia in the term group, respectively (χ(2) = 55.166; p < 0.001). When followed up to 2-7 years old, the incidence of neurodevelopmental impairment in the preterm group and term group was not significantly different (χ(2) = 0.917; p = 0.338). However, the incidence of cerebral palsy (CP) in the preterm group was significantly higher (χ(2) = 4.896; p = 0.027), while the incidence of intellectual disability (ID) (χ(2) = 9.445; p = 0.002), epilepsy (EP) (χ(2) = 23.049; p < 0.001), and CP combined with ID andEP (χ(2) = 4.122; p = 0.042) was significantly lower than that in the term group. CONCLUSIONS: Periventricular leukomalacia mainly occurred in preterm infants while subcortical cystic leukomalacia was commonly seen in term infants. Although the long-term neurodevelopmental outcomes of leukomalacia were both poor, preterm infants were more prone to CP, while term infants were more prone to ID, EP, and the combination of CP with ID and EP.

Exploring EEG resting state differences in autism: sparse findings from a large cohort / Wenyi XIAO ; Nemanja VACI ; Michael X. COHEN ; Elizabeth MILNE in Molecular Autism, 16 (2025)  

Public ISBD [article]  inMolecular Autism > 16 (2025) . - 13 p. Titre : Exploring EEG resting state differences in autism: sparse findings from a large cohort Type de document : texte imprimé Auteurs : Wenyi XIAO, Auteur ; Nemanja VACI, Auteur ; Michael X.

Langues : Anglais (eng) Mots-clés : Humans  Electroencephalography  Male  Female  Autistic Disorder/physiopathology/diagnosis  Child  Adolescent  Adult  Young Adult  Rest  Cohort Studies  Child, Preschool  Autism diagnosis  Big data  Biomarkers  Heterogeneity  NIMH data archive  Neurodevelopmental disorders  Replication  Resting state  data were drawn from the National Institute of Mental Health Data Archive (NDA).  Consent for publication: Not applicable. Competing interests: The authors declare  no competing interests. Index. décimale : PER Périodiques Résumé : BACKGROUND: Autism is a complex neurodevelopmental condition, the precise neurobiological underpinnings of which remain elusive. Here, we focus on group differences in resting state EEG (rsEEG). Although many previous reports have pointed to differences between autistic and neurotypical participants in rsEEG, results have failed to replicate, sample sizes have typically been small, and only a small number of variables are reported in each study. METHODS: Here, we combined five datasets to create a large sample of autistic and neurotypical individuals (n = 776) and extracted 726 variables from each participant's data. We computed effect sizes and split-half replication rate for group differences between autistic and neurotypical individuals for each EEG variable while accounting for age, sex and IQ. Bootstrapping analysis with different sample sizes was done to establish how effect size and replicability varied with sample size. RESULTS: Despite the broad and exploratory approach, very few EEG measures varied with autism diagnosis, and when larger effects were found, the majority were not replicable under split-half testing. In the bootstrap analysis, smaller sample sizes were associated with larger effect sizes but lower replication rates. LIMITATIONS: Although we extracted a comprehensive set of EEG signal components from the data, there is the possibility that measures more sensitive to group differences may exist outside the set that we tested. The combination of data from different laboratories may have obscured group differences. However, our harmonisation process was sufficient to reveal several expected maturational changes in the EEG (e.g. delta power reduction with age), providing reassurance regarding both the integrity of the data and the validity of our data-handling and analysis approaches. CONCLUSIONS: Taken together, these data do not produce compelling evidence for a clear neurobiological signature that can be identified in autism. Instead, our results are consistent with heterogeneity in autism, and caution against studies that use autism diagnosis alone as a method to categorise complex and varied neurobiological profiles.

METHODS: A population-based family cohort study of 4,165,785 individuals born 1973-2013 in Sweden, including 37,787 ID individuals and their relatives. The relative risks (RR) of ID with 95% confidence intervals (95% CI) were obtained from stratified Cox proportional-hazards models. Relatives of ID individuals were compared to relatives of unaffected individuals. Structural equation modeling was used to estimate heritability. RESULTS: Relatives of ID individuals were at increased risk of ID compared to individuals with unaffected relatives. The RR of ID among relatives increased proportionally to the degree of genetic relatedness with ID probands; 256.70(95% CI 161.30-408.53) for monozygotic twins, 16.47(13.32-20.38) for parents, 14.88(12.19-18.16) for children, 7.04(4.67-10.61) for dizygotic twins, 8.38(7.97-8.83) for full siblings, 4.56(4.02-5.16) for maternal, 2.90(2.49-3.37) for paternal half-siblings, 3.03(2.61-3.50) for nephews/nieces, 2.84(2.45-3.29) for uncles/aunts, and 2.04(1.91-2.20) for cousins. Lower RRs were observed for siblings of probands with chromosomal abnormalities (RR 5.53, 4.74-6.46) and more severe ID (mild RR 9.15, 8.55-9.78, moderate RR 8.13, 7.28-9.08, severe RR 6.80, 5.74-8.07, and profound RR 5.88, 4.52-7.65). Male sex of relative and maternal line of relationship with proband was related to higher risk (RR 1.33, 1.25-1.41 for brothers vs. sisters and RR 1.49, 1.34-1.68 for maternal vs. paternal half-siblings). ID was substantially heritable with 0.95(95% CI 0.93-0.98) of the variance in liability attributed to genetic influences. CONCLUSIONS: The risk estimates will benefit researchers, clinicians, families in understanding the risk of ID in the family and the whole population. The higher risk of ID related to male sex and maternal linage will be of value for planning and interpreting etiological studies in ID.

Fecal samples from children in the markers of autism risks in babies-learning early signs (MARBLES) study, a cohort with elevated likelihood of autism, were collected between 0 and 7?months of age and analyzed using 16S rRNA sequencing to evaluate whether the gut microbial composition during early infancy is associated with later neurodevelopmental diagnoses. Clinical classification as autism spectrum disorder (ASD), non-typically developing without ASD (non-TD), or typically developing (TD) was completed around 36?months of age using gold-standard assessment tools. Overall, no significant differences in alpha diversity or beta diversity, nor any differentially abundant bacterial taxa, were found between groups of infants who developed ASD or non-TD compared to those who went on to have TD. Nonetheless, our findings highlight some early differences in gut microbial composition during infancy that may relate to later neurodevelopmental outcomes. Before adjusting for multiple comparisons, infants who later developed ASD had slightly lower levels of Veillonella and Flavonifractor genera compared to children who were later found to be TD. These results suggest specific bacterial taxa may already differentiate in early infancy, but may be more subtle than other factors, such as mode of delivery and diet during early infancy. To understand longitudinal trajectories of the gut microbiome in association with later neurodevelopment, future studies should include a larger cohort to detect smaller effect sizes or investigate later time points in infancy.
