RESUMO
BACKGROUND: Return to school supports are recommended to facilitate adolescents' re-entry to school following a concussion. However, little is known as to what school stakeholders prefer for a return-to-school process. This study sought to describe the preferences of high school students, parents, and educators for a Return-to-School Framework for adolescents following a concussion. METHODS: We conducted qualitative semi-structured, 1-on-1 or group interviews with high school students (n = 6), parents (n = 5), and educators (n = 15) from Calgary, Canada. Interviews aimed to describe participants' preferences for a Return-to-School Framework for students following a concussion. Interviews were analyzed using conventional content analysis. RESULTS: We organized the data into 4 main themes: (1) purpose of the Return-to-School Framework; (2) format and operation of the Return-to-School Framework; (3) communication about a student's concussion; and (4) necessity of concussion education for students and educators. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY: A Return-to-School Framework following concussion should be developed in consultation with families, educators, and students and supports should be tailored to each student. CONCLUSIONS: Participants preferred a standardized and consistent Return-to-School Framework including ongoing communication between stakeholders as well as feasible and individualized school supports.

OBJECTIVES: Sedation and analgesia for infants and children requiring mechanical ventilation in the PICU is uniquely challenging due to the wide spectrum of ages, developmental stages, and pathophysiological processes encountered. Studies evaluating the safety and efficacy of sedative and analgesic management in pediatric patients have used heterogeneous methodologies. The Sedation Consortium on Endpoints and Procedures for Treatment, Education, and Research (SCEPTER) IV hosted a series of multidisciplinary meetings to establish consensus statements for future clinical study design and implementation as a guide for investigators studying PICU sedation and analgesia. DESIGN: Twenty-five key elements framed as consensus statements were developed in five domains: study design, enrollment, protocol, outcomes and measurement instruments, and future directions. SETTING: A virtual meeting was held on March 2-3, 2022, followed by an in-person meeting in Washington, DC, on June 15-16, 2022. Subsequent iterative online meetings were held to achieve consensus. SUBJECTS: Fifty-one multidisciplinary, international participants from academia, industry, the U.S. Food and Drug Administration, and family members of PICU patients attended the virtual and in-person meetings. Participants were invited based on their background and experience. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Common themes throughout the SCEPTER IV consensus statements included using coordinated multidisciplinary and interprofessional teams to ensure culturally appropriate study design and diverse patient enrollment, obtaining input from PICU survivors and their families, engaging community members, and using developmentally appropriate and validated instruments for assessments of sedation, pain, iatrogenic withdrawal, and ICU delirium. CONCLUSIONS: These SCEPTER IV consensus statements are comprehensive and may assist investigators in the design, enrollment, implementation, and dissemination of studies involving sedation and analgesia of PICU patients requiring mechanical ventilation. Implementation may strengthen the rigor and reproducibility of research studies on PICU sedation and analgesia and facilitate the synthesis of evidence across studies to improve the safety and quality of care for PICU patients.

BACKGROUND: Children with sickle cell disease (SCD) are at risk for physical, psychological, and social adjustment challenges. This study sought to investigate social adjustment and related factors in children living with SCD. METHODS: Data from 32 children (50% male, mean age = 10.32 years, SD = 3.27) were retrospectively collected from a neuropsychology clinic at a tertiary care pediatric hospital. Social adjustment was measured using the Behavior Assessment System for Children (BASC-3) parent-proxy, withdrawal subscale, and the Pediatric Quality of Life Inventory (PedsQL) Generic Module Social Functioning self- and parent-proxy subscales. Other measures captured executive functioning (i.e., Behavior Rating Inventory of Executive Function, Second Edition (BRIEF-2) Parent Form) and non-disease-related associations with social adjustment, including number of years in Canada and family functioning (i.e., PedsQL Family Impact Module). RESULTS: Sixteen percent of patients reported elevated social adjustment difficulties. Multiple linear regression found better family functioning [B = .48, t = 2.65, p = .016], and higher executive functioning [B = -.43, t = -2.39, p = .028] were related to higher scores on the PedsQL parent-proxy ratings of social adjustment [F(4,18) = 5.88, p = .003]. Male sex [B = .54, t = 3.08, p = .005], and having lived more years in Canada [B = .55, t = 2.81, p = .009], were related to higher PedsQL self-reported social adjustment [F(4,23) = 3.75, p = .017]. The model examining the BASC-3 withdrawal subscale was not statistically significant [F(4,16) = 1.63, p = .22]. IMPLICATIONS: Social adjustment in children diagnosed with SCD warrants future research to understand the influence of executive function, and non-disease-related factors, particularly focusing on sociocultural factors.

OBJECTIVE: Little is known about the symptoms, signs, and management guidelines for children under the age of 6 years after they sustain a concussion. Caregivers of such young children may have unique concerns and encounter different challenges from those of school-age children given the distinctive developmental characteristics of the early childhood period. This study aimed to explore the experience of caregivers through semistructured interviews to inform clinical practice. METHODS: Fifty caregivers of children aged 6 months to 5.99 years were interviewed 3 months postinjury for this qualitative study to document their experience in relation to their child's accident, recovery, and healthcare provisions. RESULTS: Four main themes were identified: (1) visible changes associated with caregiver concerns, (2) a roller-coaster of emotions after the injury, (3) healthcare providers' role in addressing the need for reassurance, and (4) the need for better information after the injury. CONCLUSION: The findings provide critical insight into the unique experiences and information needs of caregivers of young children who sustain concussion. The challenges identified can inform healthcare professionals regarding the needs of caregivers after early concussion and contribute to building a knowledge base for the development of age-appropriate anticipatory guidance for caregiver mental health and child recovery.

BACKGROUND: An estimated 1 in 5 adolescents have sustained a concussion in North America. Teachers and school administrators are responsible for implementing academic accommodations and other supports for optimal return to learn following a concussion. The primary objective of this study was to describe the prevalence and feasibility of providing academic accommodations to students following concussion from the perspectives of middle and high school teachers and school administrators. METHODS: A cross-sectional survey was administered to teachers and school administrators (grades 7-12) across Canada online via REDCap. Participants were recruited via word-of-mouth and social media sampling. Survey responses were analyzed descriptively using proportions. RESULTS: The survey was completed by 180 educators (138 teachers and 41 school administrators), of whom 86% had previously provided academic accommodations to students following concussion, and 96% agreed that students should have access to accommodations following concussion. Some accommodations (eg, breaks, extra time) were provided more often and were more feasible to provide than others (eg, no new learning, reduced bright light). Educators reported limited preparation time and limited school personnel support to assist students following concussion. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY: The most feasible accommodations should be prioritized, ensuring students are supported within the school environment. CONCLUSIONS: Teachers and school administrators confirmed the importance of providing accommodations to students following concussion.

OBJECTIVE: To examine the association between self-reported and parent-reported attention problems and hyperactivity and rates of injury and concussion in Canadian youth ice hockey players. DESIGN: Secondary analyses of 2 prospective cohort studies. SETTING: Canadian youth ice hockey teams. PARTICIPANTS: Ice hockey players (ages 11-17 years) were recruited by team, over 4 seasons (2011-2016). A combined 1709 players contributing 1996 player-seasons were analyzed (257 players participated in more than one season). ASSESSMENT OF RISK FACTORS: Data were collected from preseason baseline questionnaires, including child and parent proxy forms of the Behavior Assessment System for Children, second edition. MAIN OUTCOME MEASURES: Injury and concussion rates and incidence rate ratios (IRR) comparing players with and without self-identified or parent-identified attention problems and hyperactivity, adjusted for covariates (ie, body checking policy, previous injury/concussion, and age) and a random effect for team, were estimated using multiple multilevel negative binomial regression. RESULTS: When analyzed continuously, rates of concussion increased with higher self-reported and parent-reported measures of attention problems [IRR SELF = 1.025; 95% confidence interval (CI): 1.011-1.040; IRR PARENT = 1.032; 95% CI: 1.008-1.057]. Self-reported hyperactivity was significantly associated with concussion (IRR = 1.021; 95% CI: 1.007-1.035), but parent-reported hyperactivity was not (IRR = 1.005; 95% CI: 0.983-1.028). A T score ≥ 60 cutoff combining attention problems and hyperactivity scores (an estimate of probable attention-deficit hyperactivity disorder) was not significantly associated with rates of injury or concussion. CONCLUSIONS: Attention problems and hyperactivity may place youth ice hockey players at increased risk of concussion and injury. Preseason assessments could identify players for targeted concussion education and risk reduction strategies.

Developmental lateralization of brain function is imperative for behavioral specialization, yet few studies have investigated differences between hemispheres in structural connectivity patterns, especially over the course of development. The present study compares the lateralization of structural connectivity patterns, or topology, across children, adolescents, and young adults. We applied a graph theory approach to quantify key topological metrics in each hemisphere including efficiency of information transfer between regions (global efficiency), clustering of connections between regions (clustering coefficient [CC]), presence of hub-nodes (betweenness centrality [BC]), and connectivity between nodes of high and low complexity (hierarchical complexity [HC]) and investigated changes in these metrics during development. Further, we investigated BC and CC in seven functionally defined networks. Our cross-sectional study consisted of 211 participants between the ages of 6 and 21 years with 93% being right-handed and 51% female. Global efficiency, HC, and CC demonstrated a leftward lateralization, compared to a rightward lateralization of BC. The sensorimotor, default mode, salience, and language networks showed a leftward asymmetry of CC. BC was only lateralized in the salience (right lateralized) and dorsal attention (left lateralized) networks. Only a small number of metrics were associated with age, suggesting that topological organization may stay relatively constant throughout school-age development, despite known underlying changes in white matter properties. Unlike many other imaging biomarkers of brain development, our study suggests topological lateralization is consistent across age, highlighting potential nonlinear mechanisms underlying developmental specialization.

BACKGROUND: We described longitudinal trends in the incidence of episodes of care (EOC) and follow-up care for pediatric concussion in relation to age, sex, rurality of patient residence, point of care, and area-based socioeconomic status (SES) in Alberta, Canada. METHODS: A retrospective population-based cohort study was conducted using linked, province-wide administrative health data for all patients <18 years of age who received a diagnosis of concussion, other specified injuries of head, unspecified injury of head, or post-concussion syndrome between April 1, 2004 and March 31, 2018. Data were geospatially mapped. RESULTS: Concussion EOCs increased 2.2-fold over the study period, follow-up visits 5.1-fold. Care was increasingly received in physician office (PO) settings. Concussion diagnoses in rural and remote areas occurred in emergency department (ED) settings more often than in metro centres or urban areas (76%/75% vs. 52%/60%). Proportion of concussion diagnoses was positively related to SES and age. Diagnosis and point of care varied geographically. CONCLUSIONS: The shift in care to PO settings, increased incidence of all diagnoses, and the higher use of the ED by some segments of the population all have important implications for appropriate clinical management and the efficient provision of health care for pediatric concussion. IMPACT: This is the first study to use EOC to describe longitudinal trends in incidence and follow-up care for pediatric concussion in relation to age, sex, rurality, point of care, and area-based SES. We report increased incidence of concussion in both emergency and outpatient settings and the proportion of diagnoses was positively related to SES and age. Patients increasingly received care for concussion in PO over time. Geospatial mapping indicated that the incidence of concussion and unspecified injury of head varied geographically and temporally. Results have important implications for appropriate clinical management and efficient provision of health care following pediatric concussion.

Magnetic resonance imaging (MRI) can provide a number of measurements relevant to sport-related concussion (SRC) symptoms; however, most studies to date have used a single MRI modality and whole-brain exploratory analyses in attempts to localize concussion injury. This has resulted in highly variable findings across studies due to wide ranging symptomology, severity and nature of injury within studies. A multimodal MRI, symptom-guided region-of-interest (ROI) approach is likely to yield more consistent results. The functions of the cerebellum and basal ganglia transcend many common concussion symptoms, and thus these regions, plus the white matter tracts that connect or project from them, constitute plausible ROIs for MRI analysis. We performed diffusion tensor imaging (DTI), resting-state functional MRI, quantitative susceptibility mapping (QSM), and cerebral blood flow (CBF) imaging using arterial spin labeling (ASL), in youth aged 12-18 years following SRC, with a focus on the cerebellum, basal ganglia and white matter tracts. Compared to controls similar in age, sex and sport (N = 20), recent SRC youth (N = 29; MRI at 8 ± 3 days post injury) exhibited increased susceptibility in the cerebellum (p = 0.032), decreased functional connectivity between the caudate and each of the pallidum (p = 0.035) and thalamus (p = 0.021), and decreased diffusivity in the mid-posterior corpus callosum (p < 0.038); no changes were observed in recovered asymptomatic youth (N = 16; 41 ± 16 days post injury). For recent symptomatic-only SRC youth (N = 24), symptom severity was associated with increased susceptibility in the superior cerebellar peduncles (p = 0.011) and reduced activity in the cerebellum (p = 0.013). Fewer days between injury and MRI were associated with reduced cerebellar-parietal functional connectivity (p < 0.014), reduced activity of the pallidum (p = 0.002), increased CBF in the caudate (p = 0.005), and reduced diffusivity in the central corpus callosum (p < 0.05). Youth SRC is associated with acute cerebellar inflammation accompanied by reduced cerebellar activity and cerebellar-parietal connectivity, as well as structural changes of the middle regions of the corpus callosum accompanied by functional changes of the caudate, all of which resolve with recovery. Early MRI post-injury is important to establish objective MRI-based indicators for concussion diagnosis, recovery assessment and prediction of outcome.
RESUMO
OBJECTIVES: There is a growing demand for remote assessment options for measuring cognition after mild traumatic brain injury (mTBI). The current study evaluated the criterion validity of the Brief Test of Adult Cognition by Telephone (BTACT) in distinguishing between adults with mTBI and trauma controls (TC) who sustained injuries not involving the head or neck. METHODS: The BTACT was administered to the mTBI (n = 46) and TC (n = 35) groups at 1-2 weeks post-injury. Participants also completed the Rivermead Post Concussion Symptoms Questionnaire. RESULTS: The BTACT global composite score did not significantly differ between the groups (t(79) = -1.04, p = 0.30); the effect size was small (d = 0.23). In receiver operating characteristic curve analyses, the BTACT demonstrated poor accuracy in differentiating between the groups (AUC = 0.567, SE = 0.065, 95% CI [0.44, 0.69]). The BTACT's ability to discriminate between mTBI and TCs did not improve after excluding mTBI participants (n = 15) who denied ongoing cognitive symptoms (AUC = 0.567, SE = 0.072, 95% CI [0.43, 0.71]). CONCLUSIONS: The BTACT may lack sensitivity to subacute cognitive impairment attributable to mTBI (i.e., not explained by bodily pain, post-traumatic stress, and other nonspecific effects of injury).

OBJECTIVE: This study investigates whether acute treatment with ibuprofen, acetaminophen, or both is associated with resolution of headache or reduction of headache pain at 7 days post-concussion in children and youth. METHODS: A secondary analysis of the Predicting and Preventing Post-concussive Problems in Pediatrics (5P) prospective cohort study was conducted. Individuals aged 5-18 years with acute concussion presenting to nine Canadian pediatric emergency departments (ED) were enrolled from August 2013 to June 2015. The primary outcome was the presence of headache at 7 days, measured using the Post-Concussion Symptom Inventory. The association between acute administration of ibuprofen, acetaminophen, or both and headache presence at 7 days was investigated with propensity scores and adjusted multivariate regression models. RESULTS: 2277 (74.3%) of 3063 participants had headache upon ED presentation. Of these participants, 1543 (67.8%) received an analgesic medication before or during their ED visit [ibuprofen 754 (33.1%), acetaminophen 445 (19.5%), both 344 (15.1%); or no medication 734 (32.2%)]. Multivariate analysis pertained to 1707 participants with propensity scores based on personal characteristics and symptoms; 877 (51.4%) reported headache at 7 days post-concussion. No association emerged between treatment and presence of headache at 7 days [ibuprofen vs. untreated: (relative risk (RR) = 1.12 (95% CI 0.99,1.26); acetaminophen vs untreated RR = 1.02 (95% CI 0.87,1.22); both vs untreated RR = 1.02 (95% CI 0.86,1.18)]. CONCLUSIONS: Exposure to ibuprofen, acetaminophen, or both in the acute phase does not decrease the risk of headache at 7 days post-concussion. Non-opioid analgesics like ibuprofen or acetaminophen may be prescribed for short-term headache relief but clinicians need to be cautious with long-term medication overuse in those whose headache symptoms persist.
RéSUMé: OBJECTIF: Cette étude vise à déterminer si un traitement aigu à l'ibuprofène, à l'acétaminophène ou aux deux est associé à la résolution des maux de tête ou à la réduction de la douleur des maux de tête 7 jours après la commotion cérébrale chez les enfants et les adolescents. MéTHODES: Une analyse secondaire de l'étude de cohorte prospective Predicting and Preventing Post-concussive Problems in Pediatrics (5P) a été réalisée. Des personnes âgées de 5 à 18 ans souffrant d'une commotion cérébrale aiguë se présentant dans neuf services d'urgence pédiatriques (SU) canadiens ont été inscrites d'août 2013 à juin 2015. Le résultat primaire était la présence de maux de tête à 7 jours, mesurée à l'aide du Post-Concussion Symptom Inventory. L'association entre l'administration aiguë d'ibuprofène, d'acétaminophène ou des deux et la présence de maux de tête à 7 jours a été étudiée à l'aide de scores de propension et de modèles de régression multivariés ajustés. RéSULTATS: 2277 (74,3%) des 3063 participants avaient des maux de tête lors de la présentation aux urgences. Parmi ces participants, 1 543 (67,8%) ont reçu un médicament analgésique avant ou pendant leur visite aux urgences [ibuprofène 754 (33,1%), acétaminophène 445 (19,5%), les deux 344 (15,1%); ou aucun médicament 734 (32,2%)]. L'analyse multivariée a porté sur 1707 participants avec des scores de propension basés sur les caractéristiques personnelles et les symptômes; 877 (51,4%) ont signalé des maux de tête 7 jours après la commotion cérébrale. Aucune association n'est apparue entre le traitement et la présence de céphalées à 7 jours [ibuprofène vs non traité: (risque relatif (RR) = 1,12 (95%CI:0,99,1,26); acétaminophène vs non traité RR = 1,02 (95% IC: 0,87,1,22); les deux vs non traité RR = 1,02 (95% IC: 0,86,1,18)]. CONCLUSIONS: L'exposition à l'ibuprofène, à l'acétaminophène ou aux deux dans la phase aiguë ne diminue pas le risque de céphalées 7 jours après la commotion. Les analgésiques non opioïdes comme l'ibuprofène ou l'acétaminophène peuvent être prescrits pour soulager les maux de tête à court terme, mais les cliniciens doivent faire attention à la surconsommation de médicaments à long terme chez les personnes dont les symptômes de maux de tête persistent.

Acquired brain injury (ABI) occurs commonly in young children. Despite this, the psychosocial implications of ABI in young children are not established, with little understood about the impacts on self-perception and self-esteem. In this study we investigated self-perception, self-esteem and behaviour of children with early ABI. Children with an ABI (n = 47) before six years were compared to 17 typically developing controls (TDCs) matched on demographics. Children were aged 6-12 years and completed the Harter Self-Perception Profile. One parent completed the Child Behavior Checklist. No differences for self-perception and self-esteem were found between the groups. Parents of children with an early ABI reported more internalizing and externalizing behaviours. Children with more externalizing behaviour and social skill problems had more negative self-perceptions. Interaction effects were seen between socioeconomic status (SES) and child self-perception and behaviour. Specifically, children from families of higher SES had a more positive perception of their appearance and children from lower SES backgrounds had more externalizing behaviours and social problems. The study suggests that the relationship between ABI and self-perception and self-esteem is complicated and that children with behavioural problems have lowered feelings of competence. SES has an important role in self-perception and behavioural outcomes.

OBJECTIVES: To determine whether adolescents with persistent postconcussion symptoms (PPCS) differ from healthy peers in their personality traits and social supports. SETTING: Specialty Concussion Clinic and Primary Care Clinic affiliated with an academic medical center. PARTICIPANTS: Ninety-seven adolescents (42 with PPCS, 55 healthy peers; age: 15 ± 2 years). DESIGN: Participants completed a web-based survey that included medical and demographic characteristics, mechanisms of concussion, 10-item Big Five Inventory, and Child and Adolescent Social Support Scale. A Student's 2-tailed t test with multiple testing corrections was used to compare the youths with PPCS to healthy peers. MAIN MEASURES: The primary outcome was PPCS, defined by the presence of 2 or more concussion-related symptoms on the Post-Concussion Symptom Scale (PCSS), lasting for more than 4 weeks after initial injury. The secondary outcome was perceived personality traits and social support, based on the 10-item Big Five Inventory and the Child and Adolescent Social Support Scale, respectively. RESULTS: The PPCS group had higher neuroticism scores on their Big Five Inventory than healthy peers. They also reported less social support from teachers and classmates than healthy peers. CONCLUSION: Youths with PPCS report specific personality and social support characteristics that differ from their peers. These findings suggest that individual personality and school-based social supports may influence concussion recovery.

OBJECTIVE: To investigate whether preinjury physical, emotional, cognitive, and sleep symptoms on the Post-Concussion Symptoms Inventory (PCSI) are associated with persistent postconcussion symptoms (PPCS) at 4 weeks and whether any associations are moderated by sex or age. STUDY SETTING AND PARTICIPANTS: A total of 3063 participants with acute concussion, presenting to 9 Canadian pediatric emergency departments, were enrolled from August 2013 to June 2015. DESIGN: A planned secondary analysis of a prospective, multicenter cohort study (Predicting Persistent Post-concussive Problems in Pediatrics or 5P). Primary outcome was PPCS at 4 weeks, defined as 3 or more new or worsening individual symptoms compared with the preinjury score at 28 days on the PCSI. The association between preinjury scores and PPCS was analyzed with a multivariable logistic regression analysis that included preinjury, sex, age, sex × preinjury, and age × preinjury interactions as predictors. Missing baseline covariates were imputed. RESULTS: A total of 2123 (n = 844 [39.8%] girls; median [IQR] age = 12.9 [10.7, 15.0] participants were included in the analysis. Preinjury physical symptom score was associated with PPCS at 4 weeks (χ2 = 13.87, df = 6, P = .031). The preinjury emotional score also contributed to the variability in PPCS (χ2 = 11.79, df = 6, P = .067). While girls reported higher preinjury physical, emotional, and cognitive scores than boys, neither sex nor age interacted with preinjury to predict PPCS at 4 weeks. Independent of age and sex, preinjury physical symptoms were associated with PPCS at 4 weeks (OR = 1.40; 95% CI, 1.15-1.70). CONCLUSION: Preinjury physical symptoms are associated with the probability of having PPCS at 4 weeks postconcussion independent of age and sex. Providers should consider preinjury symptoms to inform prognosis and recovery management.

ABSTRACT: Attentional biases have been posited as one of the key mechanisms underlying the development and maintenance of chronic pain and co-occurring internalizing mental health symptoms. Despite this theoretical prominence, a comprehensive understanding of the nature of biased attentional processing in chronic pain and its relationship to theorized antecedents and clinical outcomes is lacking, particularly in youth. This study used eye-tracking to assess attentional bias for painful facial expressions and its relationship to theorized antecedents of chronic pain and clinical outcomes. Youth with chronic pain (n = 125) and without chronic pain (n = 52) viewed face images of varying levels of pain expressiveness while their eye gaze was tracked and recorded. At baseline, youth completed questionnaires to assess pain characteristics, theorized antecedents (pain catastrophizing, fear of pain, and anxiety sensitivity), and clinical outcomes (pain intensity, interference, anxiety, depression, and posttraumatic stress). For youth with chronic pain, clinical outcomes were reassessed at 3 months to assess for relationships with attentional bias while controlling for baseline symptoms. In both groups, youth exhibited an attentional bias for painful facial expressions. For youth with chronic pain, attentional bias was not significantly associated with theorized antecedents or clinical outcomes at baseline or 3-month follow-up. These findings call into question the posited relationships between attentional bias and clinical outcomes. Additional studies using more comprehensive and contextual paradigms for the assessment of attentional bias are required to clarify the ways in which such biases may manifest and relate to clinical outcomes.

BACKGROUND: Pediatric mild traumatic brain injury (mTBI) affects millions of children annually. Diffusion tensor imaging (DTI) is sensitive to axonal injuries and white matter microstructure and has been used to characterize the brain changes associated with mild traumatic brain injury (mTBI). Neurite orientation dispersion and density imaging (NODDI) is a diffusion model that can provide additional insight beyond traditional DTI metrics, but has not been examined in pediatric mTBI. The goal of this study was to employ DTI and NODDI to gain added insight into white matter alterations in children with mTBI compared to children with mild orthopedic injury (OI). METHODS: Children (mTBI n = 320, OI n = 176) aged 8-16.99 years (12.39 ± 2.32 years) were recruited from emergency departments at five hospitals across Canada and underwent 3 T MRI on average 11 days post-injury. DTI and NODDI metrics were calculated for seven major white matter tracts and compared between groups using univariate analysis of covariance controlling for age, sex, and scanner type. False discovery rate (FDR) was used to correct for multiple comparisons. RESULTS: Univariate analysis revealed no significant group main effects or interactions in DTI or NODDI metrics. Fractional anisotropy and neurite density index in all tracts exhibited a significant positive association with age and mean diffusivity in all tracts exhibited a significant negative association with age in the whole sample. CONCLUSIONS: Overall, there were no significant differences between mTBI and OI groups in brain white matter microstructure from either DTI or NODDI in the seven tracts. This indicates that mTBI is associated with relatively minor white matter differences, if any, at the post-acute stage. Brain differences may evolve at later stages of injury, so longitudinal studies with long-term follow-up are needed.

OBJECTIVES: Adverse childhood experiences (ACEs; ie, exposure to abuse, neglect, household dysfunction in childhood) are associated with poor mental and physical health outcomes across the lifespan. Emerging research suggests parent ACEs also confer risk for poor child outcomes. The relation between parent ACEs and child pain in youth with chronic pain has not yet been examined. The aim of the current longitudinal study was to examine the associations among parent ACEs, parent health, and child pain, in a clinical sample of youth with chronic pain. METHODS: In total, 192 youth (75.5% female, 10 to 18 y old) and one of their parents (92.2% female) were recruited from tertiary pediatric chronic pain clinics in Canada. At baseline, parents completed self-report measures of ACEs, chronic pain status, anxiety and depressive symptoms, and posttraumatic stress disorder symptoms. At a 3-month follow-up, youth completed self-report measures of pain intensity and pain interference. RESULTS: Regression and mediation analyses revealed that parent ACEs significantly predicted parent chronic pain status and depressive symptoms, but not parent anxiety or posttraumatic stress disorder symptoms. Moreover, parent ACEs were not significantly related to youth pain, either directly or indirectly through parent health variables. DISCUSSION: Findings suggest that an intergenerational cascade from parent ACEs to parent health to child pain was not present in the current sample. Further research that examines the role of parent ACEs in the development of child chronic pain, as well as other risk and resiliency factors that may mediate or moderate the association between parent ACEs and child chronic pain, is needed.

OBJECTIVE: The avoidance-endurance model (AEM) proposes multiple pathways from acute to chronic pain, with distinct cognitive and behavioral components in each pathway. The AEM may also be applicable to persistent symptoms after concussion. In this study, we tested the AEM as an explanatory framework for concussion outcomes, by using mediation analyses through the proposed psychological mechanisms. Based on the AEM, we hypothesized that postconcussion symptoms would significantly predict avoidance behavior through catastrophizing, and endurance behavior through thought suppression and self-distraction. PARTICIPANTS AND METHODS: We recruited 84 adults seeking treatment at 2 outpatient concussion clinics (M = 41.8 years old, 63% female) who completed measures of postconcussion symptoms, catastrophizing, thought suppression, "self-distraction" (Five Factor Mindfulness Questionnaire "Act with Awareness" Scale reverse-scored), avoidance behavior, and endurance behavior at an average of 17.8 weeks postconcussion. We conducted 3 mediation analyses to assess each of the AEM pathways. RESULTS: We found a significant indirect effect of postconcussion symptoms on avoidance behavior through catastrophizing (ab = .113 (.036), 95% CI [.053, .195]). The indirect effects of postconcussion symptoms on endurance behavior through thought suppression (ab = .011 (.012), 90% CI [.002, .035]) and "self-distraction" (ab = .003 (.009), 90% CI [.008, .022]) were not statistically significant. CONCLUSIONS: Results supported the catastrophizing-avoidance pathway in concussion, but not the thought-suppression-endurance or self-distraction-endurance pathways. Therefore, catastrophic thinking about concussion symptoms may be an appropriate treatment target for individuals who exhibit fear-avoidance behavior. Further research is needed to establish whether thought suppression and self-distraction are relevant for interventions aimed at reducing excessive endurance behavior.

OBJECTIVES: To identify the symptoms responsible for cessation of exercise testing and evaluate changes in post-concussion symptom scores on the Post-Concussion Symptom Scale (PCSS) from the Sport-Concussion Assessment Tool (SCAT5) immediately, 1-4h, and 6-12h following completion of the Buffalo Concussion Treadmill Test (BCTT) in youth and adults who have sustained a sport-related concussion. DESIGN: Prospective case-series. METHODS: Individuals who were diagnosed with a sport-related concussion and self-reported difficulties with exertion were referred to perform an exertional treadmill test. Individuals were recruited from a university sports medicine clinic. Change in PCSS symptom severity scores were operationally defined as a change ≥4 points. RESULTS: Forty-five individuals aged 13-57 years consented to participate. A total of 14/24 (58.3%) female and 13/21 (61.9%) male participants reported an increase in symptom severity scores immediately following the BCTT. At 1-4h, 5/10 (50.0%) males and 5/14 (35.7%) females who completed the PCSS had elevated symptom severity scores compared to pre-exertion. Only 24.2% (3/17 males and 5/16 females) of participants completing the PCSS at 6-12h reported increased symptom severity scores. CONCLUSION: Exertional testing is an important component of a multifaceted assessment following concussion; however, previous research evaluating symptom responses to exertion is limited. This study provides evidence to suggest individuals who experience an exacerbation of concussion-associated symptoms after exertion are likely to return to pre-exertion levels within the same day. Future research monitoring symptoms following exertion and throughout recovery should be performed in tandem with physiological measures to better understand the source of symptoms.

INTRODUCTION: Adverse childhood experiences (ACEs) are common occurrences that are related to poor health outcomes, including chronic pain, in youth and adults. Research suggests that children of parents exposed to ACEs are also at risk of poor outcomes. However, little is known about the risk that ACEs confer for chronic pain across generations. Parent ACEs may play an important role in pediatric chronic pain, given their association with key parent factors (eg, mental and physical health). OBJECTIVES: This study evaluated the prevalence of ACEs in parents of youth with chronic pain and compared these rates to a community-based sample. METHODS: One hundred seventy parents of youth (aged 10-18 years) with chronic pain, recruited from a tertiary-level chronic pain program at a pediatric hospital in Canada, completed a self-report measure of ACEs. A comparison sample (n = 3914) was drawn from a local, community-based study that examined ACEs among adults in primary care. RESULTS: Among parents of youth with chronic pain, 67.6% reported ≥1 ACE and 23.5% reported ≥4 ACEs. Controlling for sociodemographic factors, ACEs were similar across samples, except parents of youth with chronic pain reported significantly higher rates of physical neglect (odds ratio = 2.14; 95% confidence interval = 1.35-3.40) than the community-based sample. CONCLUSION: Adverse childhood experiences are prevalent among parents of youth with chronic pain, with physical neglect reported more frequently than the community-based sample. Further research that examines the association between parent ACEs and child chronic pain, as well as neurobiological and psychosocial factors that may mediate this potential relation, is needed.
