Importance: Cannabis use during pregnancy is increasingly common in the US and may affect the development and behavior of preschool-aged children.

Objective: To prospectively investigate the association of prenatal cannabis exposure with executive function and aggressive behavior at age 5 years.

Design, Setting, Participants: This cohort study was conducted from 2016 through 2020.

Graded exposure therapy for adults with persistent symptoms after mTBI: A historical comparison study.

Fear avoidance behaviour is associated with slow recovery from mild traumatic brain injury (mTBI). This study is a preliminary evaluation of graded exposure therapy (GET), which directly targets fear avoidance behaviour, for reducing post-concussion symptoms (PCS) and disability following mTBI. In a historical comparison design, we compared two groups from independent randomized trials.

Plasma Biomarkers of Traumatic Brain Injury in Adolescents With Sport-Related Concussion.

Importance: Blood-based biomarkers may clarify underlying neuropathology and potentially assist in clinical management of adolescents with sport-related concussion (SRC).

Objective: To investigate the association between SRC and plasma biomarkers in adolescents.

Design, Setting, And Participants: Prospective cohort study in Canadian sport and clinic settings (Surveillance in High Schools and Community Sport to Reduce Concussions and Their Consequences study; September 2019 to November 2022).

Exploring the link among injury severity, white matter connectivity and psychosocial outcomes in pediatric TBI: a probabilistic tractography approach.

Aim: We examined associations among injury severity, white matter structural connectivity within functionally defined brain networks and psychosocial/adaptive outcomes in children with traumatic brain injury (TBI).

Method: Participants included 58 youths (39 male) with complicated-mild TBI (cmTBI;  = 12, age =  12.6 ± 2.

Association of Psychological Resilience, Cognitive Reserve, and Brain Reserve with Post-Concussive Symptoms in Children with Mild Traumatic Brain Injury and Orthopedic Injury: An A-CAP Study.

Protective factors, including psychological resilience, cognitive reserve, and brain reserve, may be positively associated with recovery after pediatric mild traumatic brain injury (mTBI) but are yet to be studied concurrently. We sought to examine these factors as moderators of post-concussive symptoms (PCS) in pediatric mTBI compared with mild orthopedic injury (OI). Participants included 967 children (633 mTBI, 334 OI) aged 8-16.

Associations of prenatal stress with 5-year-old children's executive function in a low socioeconomic status population.

Prenatal stress has a significant, but small, negative effect on children's executive function (EF) in middle and high socioeconomic status (SES) households. Importantly, rates and severity of prenatal stress are higher and protective factors are reduced in lower SES households, suggesting prenatal stress may be particularly detrimental for children's EF in this population. This study examined whether prenatal stress was linked to 5-year-old's EF in a predominantly low SES sample and child sex moderated this association, as males may be more vulnerable to adverse prenatal experiences.

Postconcussive Symptoms After Early Childhood Concussion.

Importance: Research on postconcussive symptoms (PCS) following early childhood concussion has been hindered by a lack of measures suitable for this age group, resulting in a limited understanding of their evolution in young children.

Objective: To document PCS in the first 3 months after early childhood concussion using a developmentally appropriate measure.

Design, Setting, And Participants: This cohort study used data collected at 3 Canadian and 1 US urban pediatric emergency departments (EDs) and 8 Canadian daycares from December 2018 to December 2022 as part of the Kids' Outcomes and Long-Term Abilities (KOALA) project, a prospective, multicenter, longitudinal cohort study.

Is psychological resilience associated with changes in youth sport participants' health-related quality of life during the COVID-19 pandemic?

This study investigated the quality of life of youth sport participants over the COVID-19 pandemic as moderated by psychological resilience. Participants included 93 high school sport participants (53.76% female, mean age = 15.

Efficacy of a virtual reality-based cognitive interactive training program for children with traumatic brain injuries: study protocol for a parallel-group randomized controlled trial.

Background: Traumatic brain injury (TBI) is a leading cause of disability in children. Cognitive rehabilitation for this population is critical for their long-term health outcomes. This trial aims to evaluate the efficacy of a virtual reality-based program (VICT) for training executive functions in children with TBI.

R2DRV: study protocol for longitudinal assessment of driving after mild TBI in young drivers.

Background: Mild traumatic brain injury (mTBI) and traffic-related injuries are two major public health problems disproportionately affecting young people. Young drivers, whose driving skills are still developing, are particularly vulnerable to impaired driving due to brain injuries. Despite this, there is a paucity of research on how mTBI impacts driving and when it is safe to return to drive after an mTBI.

Do preinjury life events moderate the outcomes of mild traumatic brain injuries in children? An A-CAP Study.

Objective: To examine preinjury life events as moderators of postconcussive symptoms (PCS) and quality of life (QoL) in children with pediatric mild traumatic brain injury (mTBI) versus orthopedic injury (OI).

Methods: Participants were 633 children with mTBI and 334 with OI, ages 8-16.99, recruited from 5 pediatric emergency departments and followed for 6 months postinjury as part of a prospective cohort study.

Optimal Volume of Moderate-to-Vigorous Physical Activity Postconcussion in Children and Adolescents.

Importance: Determining the optimal volume of early moderate-to-vigorous-intensity physical activity (MVPA) after concussion and its association with subsequent symptom burden is important for early postinjury management recommendations.

Objectives: To investigate the association between cumulative MVPA (cMVPA) over 2 weeks and subsequent symptom burden at 1 week, 2 weeks, and 4 weeks postinjury in children and examine the association between cMVPA and odds of persisting symptoms after concussion (PSAC) at 2 weeks and 4 weeks postinjury.

Design, Setting, And Participants: This multicenter cohort study used data from a randomized clinical trial that was conducted from March 2017 to December 2019 at 3 Canadian pediatric emergency departments in participants aged 10.

[Formula: see text] Differences between parent- and teacher-reported executive functioning behaviors after traumatic injuries.

Deficits in executive functioning (EF) behaviors are very common following pediatric traumatic brain injury (TBI) and can linger well after acute injury recovery. Raters from multiple settings provide information that may not be appreciated otherwise. We examined differences between parent and teacher ratings of EF using data examining longitudinal outcomes following pediatric TBI in comparison to orthopedic injury (OI).

Exploring the association between cognitive activity and symptom resolution following concussion in adolescents aged 11-17 years.

Objective: As opposed to postconcussion physical activity, the potential influence of cognitive activity on concussion recovery is not well characterised. This study evaluated the intensity and duration of daily cognitive activity reported by adolescents following concussion and examined the associations between these daily cognitive activities and postconcussion symptom duration.

Methods: This study prospectively enrolled adolescents aged 11-17 years with a physician-confirmed concussion diagnosis within 72 hours of injury from the emergency department and affiliated concussion clinics.

Longitudinal changes in brain metabolites following pediatric concussion.

Concussion is commonly characterized by a cascade of neurometabolic changes following injury. Magnetic Resonance Spectroscopy (MRS) can be used to quantify neurometabolites non-invasively. Longitudinal changes in neurometabolites have rarely been studied in pediatric concussion, and fewer studies consider symptoms.

The association between symptom burden and processing speed and executive functioning at 4 and 12 weeks following pediatric concussion.

Objectives: Symptoms and cognition are both utilized as indicators of recovery following pediatric concussion, yet their interrelationship is not well understood. This study aimed to investigate: 1) the association of post-concussion symptom burden and cognitive outcomes (processing speed and executive functioning [EF]) at 4 and 12 weeks after pediatric concussion, and 2) the moderating effect of sex on this association.

Methods: This prospective, multicenter cohort study included participants aged 5.

Clinical Practice Guideline Recommendations in Pediatric Mild Traumatic Brain Injury: A Systematic Review.

Study Objective: Our primary objectives were to identify clinical practice guideline recommendations for children with acute mild traumatic brain injury (mTBI) presenting to an emergency department (ED), appraise their overall quality, and synthesize the quality of evidence and the strength of included recommendations.

Methods: We searched MEDLINE, EMBASE, Cochrane Central, Web of Science, and medical association websites from January 2012 to May 2023 for clinical practice guidelines with at least 1 recommendation targeting pediatric mTBI populations presenting to the ED within 48 hours of injury for any diagnostic or therapeutic intervention in the acute phase of care (ED and inhospital). Pairs of reviewers independently assessed overall clinical practice guideline quality using the Appraisal of Guidelines Research and Evaluation (AGREE) II tool.

Clinical Commentary: Depression and Anxiety in Adolescent and Young Adult Athletes.

Mental health (MH) symptoms and disorders are common in adolescents and young adults, and athletes may be at risk due to sport-specific triggers such as injury or illness as well as stressors related to performance, transition, or retirement from sport. Anxiety and depression are reported frequently in this age group, and early recognition and treatment can improve outcomes. The medical team (eg, athletic trainers or therapists, team physicians) should be familiar with the symptoms of depression and anxiety, recognize "red flags" for these symptoms and disorders, and seek to provide screening assessments and develop MH plans and MH emergency action plans.

Psychosocial Factors Associated With Time to Recovery After Concussion in Adolescent Ice Hockey Players.

Objective: To investigate the association between psychosocial factors and physician clearance to return to play (RTP) in youth ice hockey players after sport-related concussion.

Design: Prospective cohort study, Safe to Play (2013-2018).

Setting: Youth hockey leagues in Alberta and British Columbia, Canada.
