AI Article Synopsis
- The study investigated the effects of a hybrid intervention combining Enhanced Milieu Teaching (EMT) and JASPER on the social communication and language outcomes of young autistic children, involving 120 caregiver-child pairs.
- Results showed that while caregivers from the intervention group utilized strategies more effectively, there were no significant improvements in child outcomes compared to a control group after the intervention period or at a follow-up.
- The findings suggest that despite enhanced caregiver strategy use, the specific intervention did not lead to measurable benefits for children's social communication and language skills, indicating a need for further research in this area.
Article Abstract
Background: Studies of early caregiver-mediated interventions targeting social communication of young autistic children have yielded variable child outcomes. This study examined the effects of combining two caregiver-mediated interventions on caregiver strategy use and child social communication and language outcomes.
Method: This was a multisite parallel randomized controlled trial. Participants included 120 caregivers and their autistic children between 24 and 36 months of age. Dyads were randomly assigned to receive a hybrid intervention that combined Enhanced Milieu Teaching (EMT) and Joint Attention, Symbolic Play, Engagement, and Regulation (JASPER) or to a behavior management control condition, each delivered over 6 months. Caregivers in the JASP-EMT group received twice-weekly, in-home, and hour-long sessions. Outcomes were measured at baseline, the end of intervention (T1), and 6 months later (T2) and included a naturalistic language sample procedure, standardized measures, and caregiver report measures. This trial was registered at clinicaltrials.gov (NCT02595697).
Results: Child outcomes did not differ between conditions at T1 or T2 for child primary (social communication) or secondary (language, play, and autism symptoms) outcomes. Relative to control group caregivers, intervention group caregivers demonstrated significantly higher use of JASP-EMT strategies at T1 and T2, with the exception of two strategies (Responsiveness and Matched Responsiveness), which were used significantly more by control group caregivers. Neither autism severity nor baseline caregiver responsiveness moderated outcomes. Post hoc analyses revealed significant correlations between specific strategies and all child outcomes.
Conclusions: Twice-weekly caregiver-mediated intervention that taught caregivers of autistic children to use social communication support strategies did not yield significant child outcomes. Future studies should examine possible sources for the lack of main effects including unexpected differences in linguistic features of caregiver input, changes in control group caregiver behavior, and insufficient intervention dosage.

Objective: Marine fishing ranks among the most hazardous occupations globally, with risks intensifying for small-sized vessels venturing deeper into the sea due to the scarcity of near-shore fish and high market demand. This study identifies various occupational hazards and the use of safety equipment among small-scale motorized fishers using traditional fishing methods in the southernmost coastal regions of India.
Methods: The primary data were collected from 253 artisanal small-scale motorized fishers through a multi-stage stratified random sampling method.

Echolalia, the immediate or delayed repetition of speech, is a core diagnostic criterion for autism spectrum disorder. It has been studied for over 50 years and is well-described; however, no consensus on prevalence estimates exists for echolalia's occurrence in autistic youth. The current study sought to (1) describe endorsement of echolalia-related items using parent-, teacher-, and clinician-reports in a well-validated sample of autistic youth and (2) characterize relations between echolalia and other key factors, including age, language ability, and repetitive behaviors.

Cancer-associated fibroblasts (CAFs) are intrinsic components of the tumor microenvironment that promote cancer progression and metastasis. Through an unbiased integrated analysis of gastric tumor grade and stage, we identified a subset of proangiogenic CAFs characterized by high podoplanin (PDPN) expression, which are significantly enriched in metastatic lesions and secrete chemokine (CC-motif) ligand 2 (CCL2). Mechanistically, PDPN(+) CAFs enhance angiogenesis by activating the AKT/NF-κB signaling pathway.
