Implementing Active Support in disability day services: A 6-month prospective study on engagement and behaviours of concern among adults with intellectual disability.

BACKGROUND: Adults with intellectual disability are often disengaged in disability services. While Active Support has found efficacy in residential settings, less is known in day services. This study examines the impact of Active Support in day services for adults with intellectual disability in Singapore, particularly on engagement and behaviours of concern. METHOD: An experimental design was used, with a group of 32 participants receiving an Active Support programme over 6 months, compared to a control group of 16 participants with treatment as usual. Time sampling of behaviours was conducted every 4 weeks. RESULTS: The Active Support group saw increases in activity engagement and social engagement with staff, and decreases in disengagement and stereotypical behaviours, compared to the control group over time. CONCLUSION: Results support the implementation of Active Support across other day services for adults with intellectual disability. Active Support principles should be considered in planning policies and service outcome measures.

The Relationship Among Screen Use, Sleep, and Emotional/Behavioral Difficulties in Preschool Children with Neurodevelopmental Disorders.

OBJECTIVE: Despite evidence that excessive screen use may contribute to negative health, developmental, emotional, and behavioral outcomes, more children are engaging in increasing amounts of screen-related activities. For children with neurodevelopmental conditions, increased screen use could exacerbate emotional/behavioral difficulties (EBDs) by interfering with sleep quantity and quality. AIMS: This study examined the possible mediating role of sleep in the relationship between screen use and EBDs in preschool children with neurodevelopmental disorders (NDDs) clinically referred to a child development center in Singapore. METHODS: A screen use questionnaire developed for the purposes of the present study, the Children's Sleep Habits Questionnaire, and the Strengths and Difficulties Questionnaire were completed by 367 caregivers of 2- to 5-year-old children with NDDs (39.5% autism spectrum disorder; 36.8% speech-language disorders; 23.7% others). RESULTS: Average daily screen use duration was 3.98 hours, with 93.9% exceeding 1 hour of screen time daily. 57.7% of children had screen devices in their bedrooms, while 52% commenced screen use at the age of 18 months or earlier. Sleep problems fully mediated the relationship between the number of bedroom screen devices and children's EBDs, as well as between the age of first screen use and EBDs, but not between hours of screen use and EBDs. Controlling for age, developmental level, and family income, children who started using screens earlier than 18 months and who had screen devices in their bedrooms had significantly more sleep problems and EBDs than those without. CONCLUSION: Children with neurodevelopmental conditions may have more difficulties disengaging from screen devices in their bedrooms, and an earlier age of screen exposure may contribute to more chronic disruption of sleep.

Comparative analyses of longissimus muscle miRNAomes reveal microRNAs associated with differential regulation of muscle fiber development between Tongcheng and Yorkshire pigs.

Tongcheng (TC) and Yorkshire (YK) are two pig breeds with distinctive muscle morphology. Porcine microRNAome (miRNAome) of the longissimus muscle during five developmental stages (40, 55, 63, 70, and 90 days post coitum (dpc)) was explored by Solexa sequencing in the present study to find miRNAs involved in the different regulation of skeletal muscle development between the two breeds. A total of 320 known porcine miRNAs, 64 miRNAs corresponding to other mammals, and 224 potentially novel miRNAs were identified. Principal component analysis (PCA) and hierarchical cluster analysis (HCA) suggested that the factor "pig breed" affected the miRNA expression profiles to a lesser extent than the factor "developmental stage". Fifty-seven miRNAs were differentially expressed (DE) between the neighbor developmental stages in TC and 45 such miRNAs were found in YK, 34 in common; there were more down-regulated stage-DE miRNAs than up-regulated. And a total of 23, 30, 12, 6, and 30 breed-DE miRNAs between TC and YK were identified at 40, 55, 63, 70, and 90 dpc, respectively, which were mainly involved in cellular protein modification process, protein transport, and metabolic process. As the only highly expressed breed-DE miRNA found in no less than four developmental stages, and also a stage-DE miRNA found both in TC and YK, miR-499-5p could bind the 3'-UTR of a myofibrillogenesis regulator, destrin/actin depolymerizing factor (DSTN), as validated in dual luciferase reporter assay. The results suggested that miR-499-5p possibly play a noteworthy role in the breed-distinctive porcine muscle fiber development associated with the regulation of DSTN.
