While theory supports bidirectional effects between caregiver sensitivity and language use, and infant language acquisition-both caregiver-to-infant and also infant-to-caregiver effects-empirical research has chiefly explored the former unidirectional path. In the context of infants showing early signs of autism, we investigated prospective bidirectional associations with 6-min free-play interaction samples collected for 103 caregivers and their infants (mean age 12-months; and followed up 6-months later).
The implementation of an intervention protocol aimed at increasing vocal complexity in three pre-linguistic children with cerebral palsy (two males, starting age 15 months, and one female, starting age 16 months) was evaluated utilising a repeated ABA case series design. The study progressed until the children were 36 months of age. Weekly probes with trained and untrained items were administered across each of three intervention blocks.
Physcomitrium patens apical growing protonemal cells have the singularity that they continue to undergo cell divisions as the plant develops. This feature provides a valuable tool to study autophagy in the context of a multicellular apical growing tissue coupled to development. Herein, we showed that the core autophagy machinery is present in the moss P. patens, and characterized the 2D and 3D growth and development of atg5 and atg7 loss-of-function mutants under optimal and nutrient-deprived conditions.
Physical activity (PA) surveillance, policy, and research efforts need to be periodically appraised to gain insight into national and global capacities for PA promotion. The aim of this paper was to assess the status and trends in PA surveillance, policy, and research in 164 countries.
There is limited understanding of the challenges experienced and supports required to aid effective advocacy of the Global Action Plan on Physical Activity (GAPPA). The purpose of this study was to assess the challenges experienced and supports needed to advocate for the GAPPA across countries of different income levels.
Tuberculosis (TB) is caused by Mycobacterium tuberculosis (Mtb) and is a leading cause of death. BCG is the only licensed TB vaccine. Preclinical studies have shown that in adults, intravenous administration of BCG improves protection against TB. We hypothesize that intradermal administration of BCG to the human newborn leads to low-grade BCG bacteremia and that this systemic dissemination improves protection against Mtb infection. This hypothesis is based on supporting observations including animal and human studies. It is a testable hypothesis and offers to deliver immediately actionable insight to advance the global efforts against TB.
Most outdoor food advertising (e.g. billboards and bus stops) features foods that are considered unhealthy. The most important technical challenge when designing policies to restrict unhealthy outdoor food advertising is defining 'unhealthy food'. To date, most restriction policies have used nutrient profiling models (i.e. foods are classified according to their nutritional composition) to determine which foods and beverages may be advertised. In Australia, state governments have endorsed a food category-based classification system, with no prescribed nutrient limits, which may create ambiguity when multiple users are identifying food advertisements to be restricted.
The identification of a COPD etiotype associated with preterm birth (COPD-developmental) has expedited calls for intervention strategies that may improve health outcomes for survivors of preterm birth (<37 weeks' gestation). Pulmonary-rehabilitation style training interventions achieve physiological and symptom improvement in older people with COPD, but whether similar training interventions are suitable for young people is unclear. We sought to understand the perceived need and requirements of an exercise training intervention for children, adolescents and adults born preterm.
Survivors of preterm birth (<37 weeks' gestation) have low peak oxygen uptake, a global measure of aerobic fitness and an established predictor of increased morbidity and mortality. However, little is known about other cardiopulmonary outcome measures in this population. We addressed the hypothesis that preterm birth is associated with abnormal respiratory, cardiovascular and metabolic responses to exercise, as assessed by cardiopulmonary exercise testing, via a systematic review and meta-analysis.
Mutations in the TANGO2 gene cause an autosomal recessive disorder characterised by developmental delay, stress-induced episodic rhabdomyolysis, and cardiac arrhythmias along with severe metabolic crises. Although TANGO2 mutations result in a well characterised disease pathology, the function of TANGO2 is still unknown.
