A Self-Narrative Study: Changes in Physical Ability and Social Communication in Children with Autism through Taekwondo Training with Elements of Music Therapy from the Parents' Perspective.

Autism spectrum disorder (ASD) significantly affects social and motor skills development in early, middle or even late childhood. To promote social and motor skills development among autistic children, an intervention consisting of Taekwondo and elements of music therapy was designed and implemented in Hong Kong. The objective of the current study is to investigate the effectiveness of this training, based on parents' observations of their children who had completed the key stage of the training. Thirteen parents or caregivers (n = 13) whose children with autism participated in our Taekwondo training for two months were interviewed. Three major themes were identified by thematic analysis: (A) social skills-related change after the intervention, (B) motor skills-related change after the intervention, (C) characteristics of the intervention (i.e., session arrangement, tutor/coach attitude). Our findings show that our training was perceived by parents to have a significant impact on the promotion of physical ability and social communication in autistic children.

Family ties: maternal-offspring attachment and young adult nonmedical prescription opioid use.

BACKGROUND: Nonmedical prescription drug use is prevalent among young adults, yet little is known about modifiable determinants of use. We examined whether maternal-offspring attachment reported at mean age 21 was associated with nonmedical prescription opioid use at mean age 26, and investigated whether a history of depressive symptoms and substance use played a role in associations between maternal-offspring attachment and nonmedical prescription opioid use. METHODS: We used data from the Growing Up Today Study, a longitudinal cohort of United States adolescents followed into young adulthood. Maternal-offspring attachment was reported by young adults and their mothers, and defined as mutual low, mutual medium or high, and dissonant. Analyses were carried out in the full sample using generalized estimating equation models, and in a sibling subsample, using conditional fixed effects models to control for stable aspects of the family environment. RESULTS: Analyses with the full sample and the sibling subsample both showed that mutual medium/high maternal-offspring attachment at age 21 was associated with lower odds of nonmedical prescription opioid use at age 26 (RR=0.74; 95% CI=0.57-0.97 in full sample). The association was partly mediated by mean age 23 offspring smoking, heavy episodic drinking, and illicit drug use. CONCLUSIONS: Promoting reciprocal attachment in the maternal-offspring dyad should be investigated as a strategy to prevent nonmedical prescription opioid use by young adulthood. Even in young adulthood, programs that target both parents and offspring may have greater impact on offspring substance use than programs that target offspring alone.

Genetic analysis of viral variants selected in transmission of human immunodeficiency viruses to newborns.

Our previous studies have indicated that HIV transmission from infected mothers to infants occurs with viruses showing rapid kinetics of replication, and either resistance to maternal neutralizing antibodies or sensitivity to enhancing antibodies. The genotypic patterns that result in these and other phenotypic viral characteristics may provide clues to the selection pressures exerted during this mode of transmission. For this reason, DNA sequences of the envelope gene (env) were determined for viral isolates obtained from seropositive women who were mothers of either infected or uninfected infants. Sequences of viruses isolated early in life from the infected newborns were also determined, such that diversity both within isolates and between maternal and infant isolates could be assessed. Among isolates obtained from mothers of uninfected infants, the V3 region of env demonstrated a higher degree of heterogeneity than those from mothers of infected infants. Similar to the viruses obtained from the mothers of infected infants, the infant-derived viral sequences were relatively homogeneous. Finally, the reactivity of maternal plasma with infant-derived HIV isolates, whether via neutralizing or enhancing antibodies, appeared to predict the distribution of viral sequences in the infant isolates. These data suggest that selective pressure on HIV-1 during transmission or growth in the infected infant may be mediated by biologic and/or immunologic processes.
