Parents' and Teachers' Perspectives of Autism and Co-Morbidity Symptom Severity in Young Children with ASD Over One School Year.

Purpose: Only a few studies examined the longitudinal pattern of parent-teacher reports on autism severity and comorbidities in autism spectrum disorder (ASD) and yielded conflicting results. The study's aims were to compare parents and teachers' perception of autism, attention deficit hyperactivity disorder (ADHD) and anxiety symptoms severity in children with ASD, at the start (T1) and end (T2) of the school year, to assess changes in their perception over time and to examine correlations between their reports.

Methods: The study included 73 participants, (M = 61), aged 2:10 - 7:6 years (M = 4:10, SD = 1:0), who attended ASD special education classes and were receiving intensive interventions.

Relationship between Parental Concerns about Social-Emotional Reciprocity Deficits and Their Children's Final ASD Diagnosis.

Concerns raised by parents regarding their child's development are compatible with the child's final diagnosis of autism spectrum disorder. A better understanding of the relationship between parental concerns and a final diagnosis of autism spectrum disorder is therefore critical. In the current study, we compared the frequencies of parental concerns related to DSM-5 criteria for autism spectrum disorder between pair-matched groups with and without a final diagnosis of autism spectrum disorder and determined which parental concerns predicted a final diagnosis of autism spectrum disorder.

Implementation of fetal clinical exome sequencing: Comparing prospective and retrospective cohorts.

Purpose: We compared the diagnostic yield of fetal clinical exome sequencing (fCES) in prospective and retrospective cohorts of pregnancies presenting with anomalies detected using ultrasound. We evaluated factors that led to a higher diagnostic efficiency, such as phenotypic category, clinical characterization, and variant analysis strategy.

Methods: fCES was performed for 303 fetuses (183 ongoing and 120 ended pregnancies, in which chromosomal abnormalities had been excluded) using a trio/duo-based approach and a multistep variant analysis strategy.

A New Phylogenomic Approach For Quantifying Horizontal Gene Transfer Trends in Prokaryotes.

It is well established nowadays that among prokaryotes, various families of orthologous genes exhibit conflicting evolutionary history. A prime factor for this conflict is horizontal gene transfer (HGT) - the transfer of genetic material not via vertical descent. Thus, the prevalence of HGT is challenging the meaningfulness of the classical Tree of Life concept.
