This study describes the development of a brief, parent-report screen that relies minimally upon the child's ability to report or localize pain for identifying children with ASD at risk for one of three common gastrointestinal disorders (functional constipation, functional diarrhea, and gastroesophageal reflux disease). In a clinical sample of children with ASD, this 17-item screen identified children having one or more of these disorders with a sensitivity of 84%, specificity of 43%, and a positive predictive value of 67%. If found to be valid in an independent sample of children with ASD, the screen will be useful in both clinical practice and research.

Prenatal maternal infection and risk for autism in offspring: A meta-analysis / N. TIOLECO in Autism Research, 14-6 (June 2021)  

Public ISBD [article]  inAutism Research > 14-6 (June 2021) . - p.1296-1316 Titre : Prenatal maternal infection and risk for autism in offspring: A meta-analysis Type de document : Texte imprimé et/ou numérique Auteurs : N. TIOLECO, Auteur ; A. E. SILBERMAN, Auteur ; K. STRATIGOS, Auteur ; Sharmila BANERJEE-BASU, Auteur ; M. N. SPANN, Auteur ; A. H. WHITAKER, Auteur ; J. Blake TURNER, Auteur Article en page(s) : p.1296-1316 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder  Autistic Disorder/epidemiology  Causality  Female  Humans  Pregnancy  Pregnancy Complications  Prenatal Exposure Delayed Effects/epidemiology  Risk Factors  autism  infections  pregnancy  prenatal  risk factors Index. décimale : PER Périodiques Résumé : While prenatal maternal infection has received attention as a preventable and treatable risk factor for autism, findings have been inconsistent. This paper presents the results of a meta-analysis to determine whether the weight of the evidence supports such an association. Studies with a categorical diagnosis of autism as the outcome and an assessment of its association with prenatal maternal infection or fever (or the data necessary to compute this association) were included. A total of 36 studies met these criteria. Two independent reviewers extracted data on study design, methods of assessment, type of infectious agent, site of infection, trimester of exposure, definition of autism, and effect size. Analyses demonstrated a statistically significant association of maternal infection/fever with autism in offspring (OR = 1.32; 95% CI = 1.20-1.46). Adjustment for evident publication bias slightly weakened this association. There was little variation in effect sizes across agent or site of infection. Small differences across trimester of exposure were not statistically significant. There was some evidence that recall bias associated with status on the outcome variable leads to differential misclassification of exposure status. Nonetheless, the overall association is only modestly reduced when studies potentially contaminated by such bias are removed. Although causality has not been firmly established, these findings suggest maternal infection during pregnancy confers an increase in risk for autism in offspring. Given the prevalence of this risk factor, it is possible that the incidence of autism would be reduced by 12%-17% if maternal infections could be prevented or safely treated in a timely manner. LAY SUMMARY: This study is a meta-analysis of the association of maternal infection during pregnancy and subsequent autism in offspring. In combining the results from 36 studies of this association we find that a significant relationship is present. The association does not vary much across the types of infections or when they occur during pregnancy. We conclude that the incidence of autism could be substantially reduced if maternal infections could be prevented or safely treated in a timely manner.

Psychiatric Impairment Among Adolescents Engaging in Different Types of Deliberate Self-Harm / Colleen M. JACOBSON in Journal of Clinical Child & Adolescent Psychology, 37-2 (April-June 2008)  

Public ISBD [article]  inJournal of Clinical Child & Adolescent Psychology > 37-2 (April-June 2008) . - p.363-375 Titre : Psychiatric Impairment Among Adolescents Engaging in Different Types of Deliberate Self-Harm Type de document : Texte imprimé et/ou numérique Auteurs : Colleen M.

Blake TURNER, Auteur Année de publication : 2008 Article en page(s) : p.363-375 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : This retrospective chart review study of 227 participants examined the psychiatric profiles of outpatient adolescents ages 12 to 19 years (M = 15.08 years, SD = 1.72 years) engaging in different types of deliberate self-harm (DSH) behaviors. Participants were divided into four groups: no deliberate self-harm (NoDSH; n = 119), nonsuicidal self-injury only (NSSI only; n = 30), suicide attempt only (n = 38), and suicide attempt plus NSSI (n = 40). Those who attempted suicide were more likely to have major depressive disorder and/or posttraumatic stress disorder than those who engaged in NSSI only. Those who engaged in any type of DSH were more likely to have features of borderline personality disorder than those who did not engage in DSH. The suicidal ideation levels of those in the NSSI group were similar to those in the NoDSH group. Findings offer empirical support for the importance of distinguishing between suicidal and nonsuicidal self-harm behaviors.

Psychotic symptoms in 16p11.2 copy-number variant carriers / Amandeep JUTLA in Autism Research, 13-2 (February 2020)  

Public ISBD [article]  inAutism Research > 13-2 (February 2020) . - p.187-198 Titre : Psychotic symptoms in 16p11.2 copy-number variant carriers Type de document : Texte imprimé et/ou numérique Auteurs : Amandeep JUTLA, Auteur ; J. Blake TURNER, Auteur ; LeeAnne GREEN SNYDER, Auteur ; Wendy K. CHUNG, Auteur ; Jeremy VEENSTRA-VANDERWEELE, Auteur Article en page(s) : p.187-198 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  chromosome deletion  chromosome duplication  chromosomes  human  obsessive-compulsive disorder  pair 16  phenotype  schizophrenia spectrum and other psychotic disorders Index. décimale : PER Périodiques Résumé : 16p11.2 copy-number variation (CNV) is implicated in neurodevelopmental disorders, with the duplication and deletion associated with autism spectrum disorder (ASD) and the duplication associated with schizophrenia (SCZ). The 16p11.2 CNV may therefore provide insight into the relationship between ASD and SCZ, distinct disorders that co-occur at an elevated rate, and are difficult to distinguish from each other and from common co-occurring diagnoses such as obsessive compulsive disorder (OCD), itself a potential risk factor for SCZ. As psychotic symptoms are core to SCZ but distinct from ASD, we sought to examine their predictors in a population (n = 546) of 16p11.2 CNV carriers and their noncarrier siblings recruited by the Simons Variation in Individuals Project. We hypothesized that psychotic symptoms would be most common in duplication carriers followed by deletion carriers and noncarriers, that an ASD diagnosis would predict psychotic symptoms among CNV carriers, and that OCD symptoms would predict psychotic symptoms among all participants. Using data collected across multiple measures, we identified 19 participants with psychotic symptoms. Logistic regression models adjusting for biological sex, age, and IQ found that 16p11.2 duplication and ASD diagnosis predicted psychotic symptom presence. Our findings suggest that the association between 16p11.2 duplication and psychotic symptoms is independent of ASD diagnosis and that ASD diagnosis and psychotic symptoms may be associated in 16p11.2 CNV carriers. Autism Res 2020, 13: 187-198. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Either deletion or duplication at chromosome 16p11.2 raises the risk of autism spectrum disorder, and duplication, but not deletion, has been reported in schizophrenia (SCZ). In a sample of 16p11.2 deletion and duplication carriers, we found that having the duplication or having an autism diagnosis may increase the risk of psychosis, a key feature of SCZ.
