Bringing biomechanics to ballet: a feasibility study using wearable technology during grand allegro.

Quantifying impact accelerations during ballet class may assist load management. The largest impact accelerations occur during the sequence of large (single or double-leg) jumps (grand allegro) but are potentially the most challenging class component for utilising wearable technology, and feasibility is unknown. This pilot study utilised wearable technology during class to (1) explore feasibility and acceptability, (2) quantify impact accelerations during the entire sequence of jumps during grand allegro and (3) compare impact accelerations between limbs (preferred and non-preferred landing limb).

Cognitive Disengagement Syndrome and Autism Traits are Empirically Distinct from each Other and from Other Psychopathology Dimensions.

Recently, an association between cognitive disengagement syndrome (CDS), formerly sluggish cognitive tempo, and autism has been documented, but it is not known if the association is due to overlapping autism and CDS traits or if CDS is empirically distinct from autism. Mothers rated 2,209 children 4-17 years (1,177 with autism, 725 with ADHD-Combined type, and 307 with ADHD-Inattentive type) on the Pediatric Behavior Scale. Factor analysis of the Pediatric Behavior Scale items indicated that CDS and autism traits are empirically distinct from each other without cross-loading and are distinct from eight other factors (attention deficit, impulsivity, hyperactivity, oppositional behavior, irritability/anger, conduct problems, depression, and anxiety).

Somatic Symptoms in a Population-Based Sample from Childhood to Adolescence: Stability and Concurrent and Longitudinal Predictors.

The present study investigated group and individual stability and predictors of somatic symptoms from childhood to adolescence in a population-based sample. 259 youth were evaluated at 6-12 years (M 8.1) and 8 years later (M 15.

Reactive, Proactive, Relational, and Slow Dissipation of Aggression in Children.

Objective: This study investigated the associations between aggression subtypes (reactive, proactive, relational, and slow dissipation of aggression), callous-unemotional traits (CU), irritability (IRR), and sex among children.

Method: The sample included 508 children 5 to 12 years of age, rated by their mothers.

Results: A 4-factor model of aggression subtypes (reactive, proactive, relational, slow dissipation) provided a good fit to the data.

Pharmacokinetics and Safety of Endotracheal Lidocaine for Endotracheal Intubation in Critically Ill Children.

Introduction: Critically ill pediatric patients are endotracheally intubated in pediatric intensive care units for a variety of illnesses and indications. Management of an endotracheal tube (ETT) requires suctioning to remove patient secretions and prevent occlusion, but this practice can be associated with adverse events, such as hemodynamic deterioration or increases in intracranial pressure. Instillation of lidocaine into the ETT before suctioning may be beneficial in preventing these events.
