Diagnostic potential of IL6 and other blood-based inflammatory biomarkers in mild traumatic brain injury among children. Front Neurol 2024; 15:1432217. [PMID: 39055316 PMCID: PMC11270961 DOI: 10.3389/fneur.2024.1432217] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2024] [Accepted: 06/21/2024] [Indexed: 07/27/2024] Open
Abstract
Objectives Inflammatory biomarkers, as indicators of biological states, provide a valuable approach for accurate and reproducible measurements, crucial for the effective management of mild traumatic brain injury (mTBI) in pediatric patients. This study aims to assess the diagnostic utility of blood-based inflammatory markers IL6, IL8, and IL10 in children with mTBI, including those who did not undergo computed tomography (CT) scans. Methods A prospective multicentric cohort study involving 285 pediatric mTBI patients was conducted, stratified into CT-scanned and non-CT-scanned groups within 24 h post-trauma, alongside 74 control subjects. Biomarker levels were quantitatively analyzed using ELISA. Sensitivity and specificity metrics were calculated to determine the diagnostic efficacy of each biomarker. Results A total of 223 mTBI patients (78%) did not undergo CT scan examination but were kept in observation for symptoms monitoring at the emergency department (ED) for more than 6 h (in-hospital-observation patients). Among CT-scanned patients (n = 62), 14 (23%) were positive (CT+). Elevated levels of IL6 and IL10 were found in mTBI children compared to controls. Within mTBI patients, IL6 was significantly increased in CT+ patients compared to both CT- and in-hospital-observation patients. No significant differences were observed for IL8 among the compared groups. IL6 yielded a specificity of 48% in identifying CT- and in-hospital-observation patients, with 100% sensitivity in excluding all CT+ cases. These performances were maintained whether IL6 was measured within 6 h or within 24 h after the trauma. Conclusion The inflammatory marker IL6 emerges as a robust biomarker, showing promising stratification value for pediatric mTBI patients undergoing CT scans or staying in observation in a pediatric ED.

Abstract
PURPOSE The aim of this study was to investigate the trajectory of parent-rated post-concussive symptoms (PCS), attentional performance and participation within 6 months in children after mild traumatic brain injury (mTBI). METHODS For this prospective longitudinal study, we included data on 64 children after mTBI and 57 healthy control children (age 8-16 years). Parents rated PCS using the Post-Concussion Symptom Inventory (PCSI) immediately (T0), 1 week (T1), and 3-6 months after injury (T2). Attentional performance (alertness, selective and divided attention) was measured using the Test of Attentional Performance (TAP) at T1 and T2 and participation was measured using the Child and Adolescent Scale of Participation (CASP) at T2. RESULTS Friedman tests showed different trajectories of PCS subscales over time: Compared to pre-injury level, the amount of somatic and cognitive PCS was still elevated at T1, while emotional PCS at T1 were already comparable to pre-injury level. The rating of sleep-related PCS at T2 was significantly elevated compared to the pre-injury rating. Quade ANCOVAs indicated group differences in PCS subscales between patients and controls at T1, but not at T2. Patients and controls showed a similar performance in tests of attention at T1 and T2, but parental rating of participation at school was significantly reduced. Although cognitive PCS and attention were not correlated, there were significantly negative Spearman correlations between participation at home and pre-injury and concurrent PCS at T2. CONCLUSIONS Our data imply that sleep-related PCS are still elevated weeks after injury and are thus a target for interventions after mTBI.

Abstract
PURPOSE College students with concussion experience academic, cognitive and psychosocial challenges, yet frequently lack supports necessary for successful reintegration into school. Success in College after Concussion with Effective Student Supports (SUCCESS) is a virtual peer mentoring program designed to provide education, support and connection through a mobile application. The purpose of this study was to describe use of personas as components of mobile app development and conduct preliminary testing of SUCCESS using personas. METHODS Personas were developed from case studies and portrayed by college students trained as fictitious mentees. Mentors were blinded to use of personas. Eleven mentors completed measures pre and post a 4-week mentoring cycle. Mentors and personas interacted in the app via chat, video calls and sharing of educational materials. Measures included the Post-Concussion Symptom Scale (PCSS); PROMIS Self-Efficacy; Depression, Anxiety and Stress Scale (DASS); and a series of focus groups. RESULTS Mentors suggested improvements to resolve instability of video calls, expand educational materials to address psychosocial functioning, and add structure to the mentoring relationship. Some preferences around communication, like groups chats and emoji keyboards, were not able to be addressed. As expected, PCSS scores were stable. DASS score (p = .04), especially depression (p = .03), decreased. PROMIS scores showed a trend towards growth (p = .057), although were not statistically significant. CONCLUSIONS Use of personas allowed technical challenges and program refinements to be addressed before including students with subacute concussion in testing. Although continued development will address enhancement of communication modalities preferred by students, future efficacy testing of SUCCESS is warranted.

Abstract
BACKGROUND Predicting recovery following pediatric mild traumatic brain injury (mTBI) remains challenging. The identification of objective biomarkers for prognostic purposes could improve clinical outcomes. Telomere length (TL) has previously been used as a prognostic marker of cellular health in the context of mTBI and other neurobiological conditions. While psychosocial and environmental factors are associated with recovery outcomes following pediatric mTBI, the relationship between these factors and TL has not been investigated. This study sought to examine the relationships between TL and psychosocial and environmental factors, in a cohort of Canadian children with mTBI or orthopedic injury (OI). METHODS Saliva was collected at a postacute (median 7 days) timepoint following injury to assess TL from a prospective longitudinal cohort of children aged 8 to 17 years with either mTBI (n = 202) or OI (n = 90), recruited from 3 Canadian sites. Questionnaires regarding psychosocial and environmental factors were obtained at a postacute follow-up visit and injury outcomes were assessed at a 3-month visit. Univariable associations between TL and psychosocial, environmental, and outcome variables were assessed using Spearman's correlation. Further adjusted analyses of these associations were performed by including injury group, age, sex, and site as covariates in multivariable generalized linear models with a Poisson family, log link function, and robust variance estimates. RESULTS After adjusting for age, sex, and site, TL in participants with OI was 7% shorter than those with mTBI (adjusted mean ratio = 0.93; 95% confidence interval, 0.89-0.98; P = .003). As expected, increasing age was negatively associated with TL (Spearman's r = -0.14, P = .016). Sleep hygiene at 3 months was positively associated with TL (adjusted mean ratio = 1.010; 95% confidence interval, 1.001-1.020; P = .039). CONCLUSION The relationships between TL and psychosocial and environmental factors in pediatric mTBI and OI are complex. TL may provide information regarding sleep quality in children recovering from mTBI or OI; however, further investigation into TL biomarker validity should employ a noninjured comparison group.

Abstract
Magnetoencephalography (MEG) is an imaging technique that enables the assessment of cortical activity via direct measures of neurophysiology. It is a non-invasive and passive technique that is completely painless. MEG has gained increasing prominence in the field of pediatric neuroimaging. This dedicated review article for the pediatric population summarizes the fundamental technical and clinical aspects of MEG for the clinician. We discuss methods tailored for children to improve data quality, including child-friendly MEG facility environments and strategies to mitigate motion artifacts. We provide an in-depth overview on accurate localization of neural sources and different analysis methods, as well as data interpretation. The contemporary platforms and approaches of two quaternary pediatric referral centers are illustrated, shedding light on practical implementations in clinical settings. Finally, we describe the expanding clinical applications of MEG, including its pivotal role in presurgical evaluation of epilepsy patients, presurgical mapping of eloquent cortices (somatosensory and motor cortices, visual and auditory cortices, lateralization of language), its emerging relevance in autism spectrum disorder research and potential future clinical applications, and its utility in assessing mild traumatic brain injury. In conclusion, this review serves as a comprehensive resource of clinicians as well as researchers, offering insights into the evolving landscape of pediatric MEG. It discusses the importance of technical advancements, data acquisition strategies, and expanding clinical applications in harnessing the full potential of MEG to study neurological conditions in the pediatric population.

Abstract
Approximately 16% of patients with mild traumatic brain injury (mTBI) develop a post-concussion syndrome (PCS) with persistent physical, neurological, and behavioral complaints. PCS has a great impact on a patient's quality of life, often decreases the ability to return to work, and henceforth has a great economic impact. Recent studies suggest that early treatment can greatly improve prognosis and prevent long-term effects in these patients. However, early recognition of patients at high risk of PCS remains difficult. The objective of this systematic review is to assess risk factors associated with the development of PCS, primarily aimed at the group of non-hospitalized patients who were seen with mTBI at the emergency department (ED). We searched PubMed/MEDLINE, Cochrane Library and EMBASE on September 23, 2022, for prospective studies that assessed the risk factors for the development of PCS. Exclusion criteria were: retrospective studies; > 20% computed tomography (CT) abnormalities, <18 years of age, follow-up <4 weeks, severe trauma, and study population <100 patients. The search strategy identified 1628 articles, of which 17 studies met eligibility criteria. Risk factors found in this systematic review are pre-existing psychiatric history, headache at the ED, neurological symptoms at the ED, female sex, CT abnormalities, pre-existent sleeping problems, and neck pain at the ED. This systematic review identified seven risk factors for development of PCS in patients with mTBI. Future research should assess if implementation of these risk factors into a risk stratification tool will assist the emergency physician in the identification of patients at high risk of PCS.

Abstract
OBJECTIVE Although a majority of individuals recover from a concussion within weeks of the index injury, a substantial minority of patients report persistent postconcussion symptoms. Some of these symptoms may reflect a diagnosis of functional neurological disorder (FND). The authors evaluated the relationship between persistent postconcussion symptoms and FND symptoms. METHODS In this retrospective chart review, the authors characterized demographic and clinical information from 50 patients with a confirmed diagnosis of FND whose functional neurological symptoms started after a concussion. RESULTS Patients who developed FND after a concussion had high rates of baseline risk factors for both persistent postconcussion symptoms and FND. After the concussive event, functional neurological symptoms presented abruptly or developed insidiously over time. Functional neurological symptoms ranged widely and included gait symptoms, seizures, speech and language symptoms, weakness, sensory symptoms, tremors, and vision and oculomotor symptoms. CONCLUSIONS Functional neurological symptoms can arise after a concussion. FND should be considered in the differential diagnosis of individuals presenting with neurological symptoms beginning after a concussion. By failing to recognize functional symptoms, clinicians may inadvertently reinforce negative health-related beliefs regarding a patient's injured brain.

Abstract
BACKGROUND The German Rivermead Post-Concussion Symptoms Questionnaire (RPQ) can be used to assess post-concussion symptoms (PCS) after traumatic brain injury (TBI) in adults, adolescents, and children. METHODS In this study, we examined the psychometric properties of the German RPQ proxy version (N = 146) for children (8-12 years) after TBI at the item, total and scale score level. Construct validity was analyzed using rank correlations with the proxy-assessed Post-Concussion Symptoms Inventory (PCSI-P), the Patient Health Questionnaire 9 (PHQ-9), and the Generalized Anxiety Disorder Scale 7 (GAD-7). Furthermore, sensitivity testing was performed concerning subjects' sociodemographic and injury-related characteristics. Differential item functioning (DIF) was analyzed to assess the comparability of RPQ proxy ratings for children with those for adolescents. RESULTS Good internal consistency was demonstrated regarding Cronbach's α (0.81-0.90) and McDonald's ω (0.84-0.92). The factorial validity of a three-factor model was superior to the original one-factor model. Proxy ratings of the RPQ total and scale scores were strongly correlated with the PCSI-P (ϱ = 0.50-0.69), as well as moderately to strongly correlated with the PHQ-9 (ϱ = 0.49-0.65) and the GAD-7 (ϱ = 0.44-0.64). The DIF analysis revealed no relevant differences between the child and adolescent proxy versions. CONCLUSIONS The German RPQ proxy is a psychometrically reliable and valid instrument for assessing PCS in children after TBI. Therefore, RPQ self- and proxy-ratings can be used to assess PCS in childhood as well as along the lifespan of an individual after TBI.

Abstract
PURPOSE Given the limited availability of topic-specific resources, many people turn to anonymous social media platforms such as Reddit to seek information and connect to others with similar experiences and needs. Mining of such data can therefore identify unmet needs within the community and allow speech-language pathologists to incorporate clients' real-life insights into clinical practices. METHOD A mixed-method analysis was performed on 3,648 traumatic brain injury (TBI) subreddit posts created between 2013 and 2021. Sentiment analysis was used to determine the sentiment expressed in each post; topic modeling and qualitative content analysis were used to uncover the main topics discussed across posts. Subgroup analyses were conducted based on injury severity, chronicity, and whether the post was authored by a person with TBI or a close other. RESULTS There was no significant difference between the number of posts with positive sentiment and the number of posts with negative sentiment. Comparisons between subgroups showed significantly higher positive sentiment in posts by or about people with moderate-to-severe TBI (compared to mild TBI) and who were more than 1 month postinjury (compared to less than 1 month). Posts by close others had significantly higher positive sentiment than posts by people with TBI. Topic modeling identified three meta-themes: Recovery, Symptoms, and Medical Care. Qualitative content analysis further revealed that returning to productivity and life as well as sharing recovery tips were the primary focus under the Recovery theme. Symptom-related posts often discussed symptom management and validation of experiences. The Medical Care theme encompassed concerns regarding diagnosis, medication, and treatment. CONCLUSIONS Concerns and needs shift over time following TBI, and they extend beyond health and functioning to participation in meaningful daily activities. The findings can inform the development of tailored educational resources and rehabilitative approaches, facilitating recovery and community building for individuals with TBI.

JAMA Netw Open 2024; 7:e243182. [PMID: 38512252 PMCID: PMC10958232 DOI: 10.1001/jamanetworkopen.2024.3182] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Accepted: 01/26/2024] [Indexed: 03/22/2024] Open
Abstract
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. Participants included children aged 6 to 72 months with early childhood concussion or orthopedic injury (OI) or uninjured children from the community to serve as controls. Data were analyzed from March 2023 to January 2024. Exposure Concussion sustained between ages 6 and 72 months. Main Outcomes and Measures Primary outcomes were cognitive, physical, behavioral and total PCS assessed prior to injury (retrospectively), acutely (within 48 hours), and at 10 days, 1 month, and 3 months after injury or recruitment through caregiver observations using the Report of Early Childhood Traumatic Injury Observations & Symptoms inventory. Group comparisons were analyzed using ordinal regression models. Results The study included 303 children (mean [SD] age, 35.8 [20.2] months; 152 [50.2%] male). Of these, 174 children had a concussion (mean [SD] age, 33.3 [19.9] months), 60 children had an OI (mean [SD] age, 38.4 [19.8] months) and 69 children were uninjured controls (mean [SD] age, 39.7 [20.8] months). No meaningful differences were found between the concussion and comparison groups in retrospective preinjury PCS. Significant group differences were found for total PCS at the initial ED visit (concussion vs OI: odds ratio [OR], 4.33 [95% CI, 2.44-7.69]; concussion vs control: OR, 7.28 [95% CI, 3.80-13.93]), 10 days (concussion vs OI: OR, 4.44 [95% CI, 2.17-9.06]; concussion vs control: OR, 5.94 [95% CI, 3.22-10.94]), 1 month (concussion vs OI: OR, 2.70 [95% CI, 1.56-4.68]; concussion vs control: OR, 4.32 [95% CI, 2.36-7.92]), and 3 months (concussion vs OI: OR, 2.61 [95% CI, 1.30-5.25]; concussion vs control: OR, 2.40 [95% CI, 1.36-4.24]). Significant group differences were also found for domain-level scores (cognitive, physical, behavioral) at various time points. Conclusions and Relevance In this early childhood cohort study, concussion was associated with more PCS than OIs or typical development up to 3 months after injury. Given the limited verbal and cognitive abilities typical of early childhood, using developmentally appropriate manifestations and behaviors is a valuable way of tracking PCS and could aid in concussion diagnosis in young children.

Abstract
OBJECTIVES To identify trajectories of daily postconcussion symptoms (PCS) from the acute postinjury period to symptom resolution among concussed children and examine demographic factors and acute PCS associated with the identified symptom trajectories. SETTING AND PARTICIPANTS Seventy-nine participants with a concussion were enrolled within 72 hours of injury and completed a daily survey that assessed PCS from enrollment until symptom resolution. DESIGN This was a prospective cohort study among concussed children aged 11-17 years. MAIN MEASURES Children rated their concussion symptoms daily using the Post-Concussion Symptom Scale. Symptom duration was assessed using participants' date of symptom resolution and coded as a dichotomous variable: (1) PCS duration 14 days or less or (2) PCS duration longer than 14 days. RESULTS Of the 79 participants, most were male ( n = 53, 67%), injured during a sporting activity ( n = 67, 85%), or had PCS that persisted for more than 14 days post-injury ( n = 41, 52%). Group-based trajectory modeling yielded 4 trajectory groups: (1) low acute/resolved PCS ( n = 39, 49%), (2) moderate/persistent PCS ( n = 19, 24%), (3) high acute/persistent PCS ( n = 13, 16%), and (4) high acute/resolved PCS ( n = 8, 10%). No significant associations were found between demographic factors and the trajectory group. A higher symptom burden at injury was associated with an increased odds of being in the high acute/resolved or high acute/persistent recovery groups than being in the low acute/resolved group (odds ratio [OR] 1.39, 95% CI = 1.11-1.74; OR = 1.33, 95% CI = 1.11-1.60, respectively), as was a higher symptom severity at injury (OR = 1.09, 95% CI = 1.03-1.15; OR = 1.06, 95% CI = 1.02-1.11, respectively). CONCLUSION Our findings may help clinicians identify concussed children on slower recovery trajectories, and implement early, individualized treatment plans that foster optimal recovery for concussed children.

Abstract
PRIMARY OBJECTIVE To gain an understanding of current evaluation practices, post-injury recommendations, and referrals to allied healthcare professions (AHP) by first-line healthcare professionals (FHPs) providing care for people with mild traumatic brain injury (mTBI). RESEARCH DESIGN Survey study. METHODS AND PROCEDURES Physicians, physician assistants, nurse practitioners, nurses, and athletic trainers (n = 126) completed an online survey, including Likert scale and free response question relating to mTBI evaluation, management, and referral practices. MAIN OUTCOMES AND RESULTS FHPs surveyed reported being confident in their ability to evaluate patients with suspected mTBI, relying most heavily on patient-reported symptoms and physical signs as methods of evaluation. Most FHPs reported making recommendations to compensate for the symptoms experienced following mTBI diagnosis. In contrast, FHPs expressed challenges in the evaluation and management of symptoms associated with mTBI along with limited knowledge of and referrals to AHPs. CONCLUSIONS Overall, FHPs feel confident in the diagnosis of mTBI but experience assessment and management challenges. AHPs are underutilized on mTBI management teams calling for a need for multidisciplinary collaboration on research, education, and rehabilitation efforts to optimally care for people experiencing mTBI symptoms.

Abstract
Although awareness regarding patients with mild traumatic brain injury has increased, they have not received sufficient attention in clinics; hence, many patients still experience only partial recovery. Deficits in decision-making function are frequently experienced by these patients. Accurate identification of impairment in the early stages after brain injury is particularly crucial for timely intervention and the prevention of long-term cognitive consequences. Therefore, we investigated the changes in decision-making ability under tasks of ambiguity and risk in patients with mild traumatic brain injury with a rule-based neuropsychological paradigm. In this study, patients (n = 39) and matched healthy controls (n = 38) completed general neuropsychological background tests and decision-making tasks (Iowa Gambling Task and Game of Dice Task). We found that patients had extensive cognitive impairment in general attention, memory and information processing speed in the subacute phase, and confirmed that patients had different degrees of impairment in decision-making abilities under ambiguity and risk. Furthermore, the decline of memory and executive function may be related to decision-making dysfunction.

Abstract
Although all states have legislation pertaining to youth sports concussion, most of these laws focus on return-to-play procedures; only a few address return-to-learn (RTL) accommodations for students who have experienced a concussion. To address this gap in the legislation, some states and nongovernmental organizations have developed RTL guidelines to advise school personnel, parents, and health care providers on best practices for accommodating students' postconcussion reintegration into academic activity. In 2018, the Massachusetts Department of Public Health (MDPH) developed RTL guidelines which were disseminated to school nurses (SNs) at all public and nonpublic middle and high schools in the state. In 2020, the MDPH engaged the Injury Prevention Center at Boston Medical Center to survey Massachusetts SNs to assess the usefulness of the guidelines. The response rate was 63%; 92% found the booklet extremely useful or moderately useful; and 70% endorsed that the booklet fostered collaboration among stakeholders.

Abstract
PURPOSE Examine concussion effects on academic outcomes, including student perspectives. METHODS This study included a systematic review and meta-analysis examining post-concussion school attendance, academic performance, perceptions of academic difficulty, and accommodations for students in elementary through college settings. The analysis considered pre- and post-injury factors, along with injury factors that contribute to post-concussion academic outcomes. RESULTS The systematic review showed that students with concussion miss more school days and perceive higher levels of academic difficulty, but results about academic performance varied. Meta-analysis yielded small concussion effects on school absence and academic performance and moderate effects on perceptions of academic difficulty. Female sex, older age, history of migraine, prior concussions, severe or persistent symptoms, vestibular-ocular motor, and cognitive disruptions are risk factors, but these moderators were not identified in the meta-analysis due to lack of effect sizes. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY This study confirmed negative concussion effects on academic absences, performance, and perceptions of academic difficulty. Identified contributing factors will guide future practices to support students returning to learn after concussion. CONCLUSIONS Negative impacts to academics from concussion may be amplified by complicating factors. Future investigations are needed to confirm risk factors and mitigating effects of early identification and post-injury supports.

Abstract
Adolescent chronic pain is a growing public health epidemic. Our understanding of its etiology is limited; however, several factors can increase susceptibility, often developing in response to an acute pain trigger such as a surgical procedure or mild traumatic brain injury (mTBI), or an adverse childhood experience (ACE). Additionally, the prevalence and manifestation of chronic pain is sexually dimorphic, with double the rates in females than males. Despite this, the majority of pre-clinical pain research focuses on males, leaving a gap in mechanistic understanding for females. Given that emerging evidence has linked the gut microbiome and the brain-gut-immune axis to various pain disorders, we aimed to investigate sex-dependent changes in taxonomic and functional gut microbiome features following an ACE and acute injury as chronic pain triggers. Male and female Sprague Dawley rat pups were randomly assigned to either a maternal separation (MS) or no stress paradigm, then further into a sham, mTBI, or surgery condition. Chronically, the von Frey test was used to measure mechanical nociception, and fecal samples were collected for 16S rRNA sequencing. Animals in the surgery group had an increase in pain sensitivity when compared to mTBI and sham groups, and this was complemented by changes to the gut microbiome. In addition, significant sex differences were identified in gut microbiome composition, which were exacerbated in response to MS. Overall, we provide preliminary evidence for sex differences and ACE-induced changes in bacterial composition that, when combined, may be contributing to heterogeneity in pain outcomes.

Post-Traumatic Stress as a Psychological Effect of Mild Head Injuries in Children. CHILDREN (BASEL, SWITZERLAND) 2023; 10:1115.

Abstract
BACKGROUND Head trauma is one of the most common pediatric emergencies. While the psychological effects of severe head injuries are well studied, the psychological consequences of mild head injuries often go overlooked. Head injuries with a Glasgow Coma Scale score of 13-15, with symptoms such as headache, vomiting, brief loss of consciousness, transient amnesia, and absence of focal neurological signs, are defined as mild. The aim of this study is to evaluate the stress of children with mild head injuries and their parents' relevant perception during the early post-traumatic period. METHODS This is a prospective cross-sectional study on a cohort of children with mild head injuries and their parents. Two questionnaires were implemented, the Child Trauma Screening Questionnaire (CTSQ) which was compiled by the children, and the Children's Revised Impact of Event Scale (CRIES-13), compiled by their parents. Both questionnaires are widely used and reliable. The first presents an excellent predictive ability in children with a risk of post-traumatic stress disorder, while the second is a weighted self-completed detecting instrument for the measurement of post-traumatic stress in children and adolescents, with a detailed evaluation of their reactions to the traumatic incident. The participants responded one week and one month after the traumatic event. RESULTS A total of 175 children aged 6-14 years and 174 parents participated in the study. Stress was diagnosed in 33.7% of children after one week, and in 9.9% after one month. Parental responses suggesting stress presence in their children were 19.0% and 3.9%, respectively. These outcomes showed that mild head injuries are not so innocent. They are often underestimated by their parents and may generate a psychological burden to the children during the early post-traumatic period. CONCLUSIONS Mild head injuries may affect the emotional welfare of children. Healthcare providers should understand the importance of the psychological effect of this overlooked type of injury. They should be trained in the psychological effect of trauma and be aware of this probability, promptly notify the parents accordingly, and provide psychological assistance beyond medical treatment. Follow-up and support are needed to avoid the possibility of future post-traumatic stress disorder. More extensive research is needed as the outcomes of this study regarded a limited population in numbers, age, and survey period. Furthermore, many children with mild head injuries do not ever visit the emergency department and stay at home unrecorded. Community-based research on the topic should therefore be considered.

Abstract
In the field of pediatric traumatic brain injury (TBI), relationships between pre-injury and injury-related characteristics and post-TBI outcomes (functional recovery, post-concussion depression, anxiety) and their impact on disease-specific health-related quality of life (HRQoL) are under-investigated. Here, a multidimensional conceptual model was tested using a structural equation model (SEM). The final SEM evaluates the associations between these four latent variables. We retrospectively investigated 152 children (8-12 years) and 148 adolescents (13-17 years) after TBI at the recruiting clinics or online. The final SEM displayed a fair goodness-of-fit (SRMR = 0.09, RMSEA = 0.08 with 90% CI [0.068, 0.085], GFI = 0.87, CFI = 0.83), explaining 39% of the variance across the four latent variables and 45% of the variance in HRQoL in particular. The relationships between pre-injury and post-injury outcomes and between post-injury outcomes and TBI-specific HRQoL were moderately strong. Especially, pre-injury characteristics (children's age, sensory, cognitive, or physical impairments, neurological and chronic diseases, and parental education) may aggravate post-injury outcomes, which in turn may influence TBI-specific HRQoL negatively. Thus, the SEM comprises potential risk factors for developing negative post-injury outcomes, impacting TBI-specific HRQoL. Our findings may assist healthcare providers and parents in the management, therapy, rehabilitation, and care of pediatric individuals after TBI.

Abstract
This study investigated associations between psychological resilience and characteristics of white matter microstructure in pediatric concussion. This is a case control study and a planned substudy of a larger randomized controlled trial. Children with an acute concussion or orthopedic injury were recruited from the emergency department. Participants completed both the Connor-Davidson Resilience Scale 10 and an MRI at 72 h and 4-weeks post-injury. The association between resiliency and fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD) at both timepoints were examined. We examined whether these associations were moderated by group. The association between resiliency captured at 72 h and diffusion tensor imaging metrics at 4 weeks was also investigated. Clusters were extracted using a significance threshold of threshold-free cluster enhancement corrected p < .05. A total of 66 children with concussion (median (IQR) age = 12.88 (IQR: 11.80-14.36); 47% female) and 29 children with orthopedic-injury (median (IQR) age = 12.49 (IQR: 11.18-14.01); 41% female) were included. A negative correlation was identified in the concussion group between 72 h resilience and 72 h FA. Meanwhile, positive correlations were identified in the concussion group with concussion between 72 h resilience and both 72 h MD and 72 h RD. These findings suggest that 72 h resilience is associated with white matter microstructure of the forceps minor, superior longitudinal fasciculus, and anterior thalamic radiation at 72 h post-concussion. Resilience seems to be associated with neural integrity only in the acute phase of concussion and thus may be considered when researching concussion recovery.

Abstract
BACKGROUND Students with traumatic brain injury (TBI) often demonstrate difficulties that impact their successful return to school (RTS). OBJECTIVE To explore injury severity, age at injury, and time since injury as predictors for performance on measures of cognitive, social and health functioning for students' participating in a formal RTS cohort at the time of their enrollment in the School Transition After Traumatic Brain Injury (STATBI) research project. METHODS Outcome measures across cognitive, social, and health domains were analyzed for association with the explanatory variables of interest using quantile regressions and ordinary least squares regression, as appropriate. RESULTS Students (N = 91) injured after age 13 showed significantly lower cognitive outcomes than students whose injury occurred earlier. Additionally, students more than one-year post-injury demonstrated poorer social outcome on one measure compared to students whose injury occurred more recently. Health outcomes showed no significant association to any predictors. CONCLUSION The results of this analysis provide a baseline for a group of students with TBI as they enter a RTS research study. This data can now be paired with longitudinal measures and qualitative data collected simultaneously to gain a deeper understanding of how students with TBI present for RTS.

Abstract
Concussions are caused by a hit or blow to the head that alters normal brain functioning. The Success in College after Concussion with Effective Student Supports (SUCCESS) program was developed to provide students with psychosocial support and resources-both key components of concussion management-to assist in recovery and return-to-learn following concussion. In this preliminary evaluation of intervention efficacy, SUCCESS was delivered through a mobile application connecting mentors (students who have recovered from concussion and successfully returned to school) with mentees who were currently recovering. Mentor-mentee pairs met virtually through the app, using chat and videoconferencing features to share support, resources, and program-specific educational materials. Results from 16 mentoring pairs showed that mentee symptoms (V = 119, p = 0.009) and academic problems decreased (V = 114.5, p = 0.002), while academic self-efficacy increased (V = 13.5, p = 0.009) following mentoring. As expected, mentor measures were stable, indicating that providing mentoring did not exacerbate previously resolved concussion complaints. Virtual peer mentoring provided through a mobile application may be a feasible intervention to support academic success and psychosocial processing during recovery for college students with concussion.

Abstract
OBJECTIVES To measure the association between psychosocial problems and persistent post-concussive symptoms (PCS) in youth who were seen in the emergency department with mild traumatic brain injury (mTBI) or orthopedic injury (OI). METHODS From a larger prospective cohort study, Advancing Concussion Assessment in Pediatrics (A-CAP), 122 child-guardian pairs who presented to the emergency department with mTBI (N = 70) or OI (N = 52) were recruited for this cross-sectional sub-study. Each pair completed 2 measures assessing PCS burden at 2 weeks, 3 months, and 6 months post-injury. At one visit, pairs concurrently completed MyHEARTSMAP, a comprehensive, psychosocial self-assessment tool to evaluate 4 domains of mental wellness. RESULTS When measured at the same visit, children who self-reported moderate or severe Psychiatry domain concerns concurrently experienced a greater burden of cognitive symptoms (β = 5.49; 0.93-10.05) and higher overall PCS count (β = 2.59; 0.70-4.48) after adjusting for covariables, including retrospective pre-injury symptoms and injury group. Additionally, reports indicating mild Function domain severity were associated with increased cognitive (β = 3.34; 95% CI: 0.69-5.99) and somatic symptoms (β = 6.79; 2.15-11.42) and total symptom count (β = 1.29; 0.18-2.39). CONCLUSION Increasing severity in multiple domains of mental health is associated with more PCS in youth. While the differences in PCS between the mTBI and OI groups appeared somewhat larger for children with more mental health concerns, the interaction was not statistically significant; larger sample sizes are needed to evaluate the moderating effect of psychosocial difficulties on post-concussion symptoms.

Psychometric Properties of the German Version of the Rivermead Post-Concussion Symptoms Questionnaire in Adolescents after Traumatic Brain Injury and Their Proxies. J Clin Med 2022; 12:jcm12010319.

Abstract
The Rivermead Post-Concussion Symptoms Questionnaire (RPQ) assesses post-concussion symptoms (PCS) after traumatic brain injury (TBI). The current study examines the applicability of self-report and proxy versions of the German RPQ in adolescents (13-17 years) after TBI. We investigated reliability and validity on the total and scale score level. Construct validity was investigated by correlations with the Post-Concussion Symptoms Inventory (PCSI-SR13), Generalized Anxiety Disorder Scale 7 (GAD-7), and Patient Health Questionnaire 9 (PHQ-9) and by hypothesis testing regarding individuals' characteristics. Intraclass correlation coefficients (ICC) assessed adolescent-proxy agreement. In total, 148 adolescents after TBI and 147 proxies completed the RPQ. Cronbach's α (0.81-0.91) and McDonald's ω (0.84-0.95) indicated good internal consistency. The three-factor structure outperformed the unidimensional model. The RPQ was strongly correlated with the PCSI-SR13 (self-report: r = 0.80; proxy: r = 0.75) and moderately-strongly with GAD-7 and PHQ-9 (self-report: r = 0.36, r = 0.35; proxy: r = 0.53, r = 0.62). Adolescent-proxy agreement was fair (ICC [2,1] = 0.44, CI95% [0.41, 0.47]). Overall, both self-report and proxy assessment forms of the German RPQ are suitable for application in adolescents after TBI. As proxy ratings tend to underestimate PCS, self-reports are preferable for evaluations. Only if a patient is unable to answer, a proxy should be used as a surrogate.

Abstract
Dysregulation of the gut microbiome has been shown to perpetuate neuroinflammation, alter intestinal permeability, and modify repetitive mild traumatic brain injury (RmTBI)-induced deficits. However, there have been no investigations regarding the comparative effects that the microbiome may have on RmTBI in adolescents and adults. Therefore, we examined the influence of microbiome depletion prior to RmTBI on microbial composition and metabolome, in adolescent and adult Sprague Dawley rats. Rats were randomly assigned to standard or antibiotic drinking water for 14 days, and to subsequent sham or RmTBIs. The gut microbiome composition and metabolome were analysed at baseline, 1 day after the first mTBI, and at euthanasia (11 days following the third mTBI). At euthanasia, intestinal samples were also collected to quantify tight junction protein (TJP1 and occludin) expression. Adolescents were significantly more susceptible to microbiome depletion via antibiotic administration which increased pro-inflammatory composition and metabolites. Furthermore, RmTBI induced a transient increase in 'beneficial bacteria' (Lachnospiraceae and Faecalibaculum) in only adolescents that may indicate compensatory action in response to the injury. Finally, microbiome depletion prior to RmTBI generated a microbiome composition and metabolome that exemplified a potentially chronic pathogenic and inflammatory state as demonstrated by increased Clostridium innocuum and Erysipelatoclostridium and reductions in Bacteroides and Clostridium Sensu Stricto. Results highlight that adolescents are more vulnerable to RmTBI compared to adults and dysbiosis prior to injury may exacerbate secondary inflammatory cascades.

Abstract
PURPOSE This study examines school-based speech-language pathologists' (SLPs') experience, knowledge, and confidence in supporting students as they return to the classroom following concussion, with a particular focus on knowledge of new management guidelines over the last decade. METHOD Participants were 74 school-based SLPs who completed an electronic survey about their knowledge and experiences serving students with concussion. We examined participants' accuracy and confidence across knowledge questions using Kruskal-Wallis tests. We also conducted linear regression to explore the relationships between training, work experiences, knowledge, and confidence. RESULTS Nearly half of participants who are currently working with students with concussion reported having no clinical or training experiences related to concussion. Participants who had more concussion-related training or working experiences reported higher confidence. Participants were confident about general concussion knowledge but less confident about providing assessment and supporting students with concussion as they returned to school. Participants had the lowest confidence and accuracy for the most recent guidelines around rest and activity, as well as the differential impact of concussion on children as compared to adults. CONCLUSIONS Many school-based SLPs have limited training around concussion management and are often not specifically consulted to work with students following concussion. Despite this, SLPs have good awareness of their knowledge about concussion, but show gaps in knowledge surrounding more recent evidence-based guidelines. Additional investigation is needed to determine better ways to move research into clinical practice and to increase the involvement of SLPs in school-based concussion teams.

Abstract
OBJECTIVE A significant minority of adolescents will have persistent postconcussion symptoms after an injury, potentially having a negative impact on family functioning. However, the reasons for a family's negative impact are not clearly understood. The objective of this study was to determine whether preinjury/demographic factors, injury characteristics, and/or worse postinjury symptoms are associated with higher levels of family stress in youth with refractory postconcussion symptoms. SETTING Pediatric refractory concussion clinic in a tertiary care center. PARTICIPANTS A total of 121 adolescents (13-18 years old) who were 1 to 12 months postconcussion. MEASURES Primary outcome was the mean stress rating on the Family Burden of Injury Interview (FBII), a 27-item questionnaire rating the impact on a family as a result of an injury. Preinjury/demographic and injury details were collected. Youth and their parents also completed measures of postconcussion symptoms, depression, anxiety, and behavioral problems. RESULTS Participants had a mean age of 16.0 years (SD = 1.3), of which, 65% identified as female, and were on an average 5.2 months (SD = 2.4) postconcussion. FBII ratings were not significantly correlated with demographics, preinjury functioning, injury severity, duration of persistent postconcussion problems (ie, time since injury), or self-reported postconcussion symptoms. Greater family burden (higher FBII ratings) significantly correlated with worse parent-reported postconcussion symptoms, worse psychological functioning (self-reported depression, parent-reported anxiety, and depression), and worse behavioral functioning (parent-reported conduct problems and peer problems). A multiple linear regression model revealed that parent-perceived postconcussion cognitive symptoms (β = .292, t = 2.56, P = .012) and parent-perceived peer problems (β = .263, t = 2.59, P = .011) were significantly associated with family burden ( F8,105 = 6.53; P < .001; R2 = 0.35). CONCLUSION Families of youth with refractory postconcussion symptoms can experience a negative impact. The severity of reported family burden in those with slow recovery from concussion was significantly associated with parents' perception of their child's cognitive symptoms and peer problems. These results could provide support for family-based interventions in this population.

Abstract
OBJECTIVE To provide a systematic review of studies examining the proportion of children with persistent postconcussive symptoms (PPCS) and to examine potential moderators of prevalence. STUDY DESIGN Searches were conducted in MEDLINE, Embase, PsycINFO, Scopus, and Cochrane Central Register of Controlled Trials on April 16, 2020. Criteria for study inclusion were children aged <18 years with concussion or mild traumatic brain injury, operational definition of PPCS, assessment of postconcussive symptoms at least 4 weeks postinjury, sample sizes and proportion with PPCS available, and study published in English. Definition of PPCS, sample size, proportion of participants identified with PPCS, child sex and age at injury, time postinjury, premorbid symptoms, diagnosis (concussion or mild traumatic brain injury), and study publication year were extracted from each article. Study quality was assessed using the Newcastle-Ottawa Scale. RESULTS Thirteen studies, with a total of 5307 participants, were included in our analysis. The proportion of children identified with PPCS was 35.1% (weighted average; 95% CI, 26.3%-45.0%). The prevalence of PPCS was higher in older and female children who presented for care at concussion clinics, and in more recent publications. CONCLUSIONS Approximately one-third of children with concussion/mild traumatic brain injury will experience PPCS. Age, sex, and point of care could help identify children at high risk for PPCS.

Abstract
OBJECTIVE To explore adolescent and parent perceptions of the impact of a concussion/mild traumatic brain injury (mTBI) on family functioning and activity levels in the first 4 weeks of recovery. SETTING Outpatient research setting. PARTICIPANTS Twenty-seven adolescents (aged of 13-17 years) within 1 week of a concussion/mTBI and a parent/guardian were enrolled in the study. DESIGN Prospective ecological study with qualitative, semistructured interviews. MAIN MEASURES Adolescents reported symptoms electronically every 2 days for 28 days via the Post-Concussion Symptom Inventory. Semistructured interviews were completed with each adolescent-parent dyad at the end of the 28-day period. Interview questions focused on perceptions of recovery progress and study procedures. RESULTS Symptom trajectories were variable across participants. Three main themes emerged from thematic analysis, including: (1) disruption of routines and activities, (2) injury management considerations, and (3) positive and negative influential factors (eg, school and coach support, timing of injury, and recovery expectations). Results highlighted nuances of recovery challenges that families specifically face and help emphasize the potential benefits of shared decision-making and where more guidance would be appreciated such as more specific self-management of symptoms and physical activity reintegration strategies. CONCLUSIONS Study findings support a shared decision-making approach with the identified themes as potential topics to help consider social and environmental influences on recovery. The themes presented in the results could be topics emphasized during intake and follow-up visit processes to help guide plans of care and return-to-activity decisions.

Abstract
IMPORTANCE Concussions are common among children and youth. To date, the pediatric concussion literature has focused on quantitative reports of the effects of concussion and return-to-activity guidelines. However, the subjective experiences of children and youth returning to occupations postconcussion have largely been ignored. An understanding of these experiences is critical to inform effective concussion management. OBJECTIVE To investigate the experiences of children and youth returning to occupations after sustaining a concussion and the impacts on their future engagement in occupation. DESIGN Qualitative interpretive description was used for data analysis and interpretation. SETTING Community. PARTICIPANTS Children and youth ages 11 to 18 yr from a cohort study were recruited to be interviewed about their experiences of engaging in occupations postconcussion. OUTCOMES AND MEASURES Interviews were conducted 3 to 24 mo postconcussion, transcribed verbatim, and analyzed using interpretive description to identify themes. RESULTS Eight children and youth (5 male, 3 female) were included. Analyses revealed three themes of the experiences of children and youth returning to occupations after concussion: diverse experiences of concussion, knowledge is key to concussion management, and concussions affect occupational engagement. CONCLUSIONS AND RELEVANCE This study highlights the importance of considering a person's needs to enable effective concussion treatment plans. The results suggest the need for an occupation-based framework to guide interventions in pediatric concussion management. What This Article Adds: Our findings indicate that children and youth report variable recovery patterns, a lack of knowledge about concussion recovery, and a negative effect of concussion on occupational engagement.

Abstract
Background Up to one-third of concussed children develop persistent post-concussive symptoms (PPCS). The identification of biomarkers such as salivary miRNAs that detect concussed children at increased risk of PPCS has received growing attention in recent years. However, whether and how salivary miRNA expression levels differ over time between concussed children with and without PPCS is unknown. Aim To identify salivary MicroRNAs (miRNAs) whose expression levels differ over time post-concussion in children with vs. without PPCS. Methods We conducted a prospective cohort study with saliva collection at up to three timepoints: (1) within one week of injury; (2) one to two weeks post-injury; and (3) 4-weeks post-injury. Participants were children (ages 11 to 17 years) with a physician-diagnosed concussion from a single hospital center. We collected participants' daily post-concussion symptom ratings throughout their enrollment using the Post-concussion Symptom Scale, and defined PPCS as a total symptom score of ≥ 5 at 28 days post-concussion. We extracted salivary RNA from the saliva samples and measured expression levels of 827 salivary miRNAs. We then compared the longitudinal expression levels of salivary miRNAs in children with vs. without PPCS using linear models with repeated measures. Results A total of 135 saliva samples were collected from 60 children. Of the 827 miRNAs analyzed, 91 had expression levels above the calculated background threshold and were included in the differential gene expression analyses. Of these 91 miRNAs, 13 had expression levels that differed significantly across the three timepoints post-concussion between children with and without PPCS (i.e., hsa-miR-95-3p, hsa-miR-301a-5p, hsa-miR-626, hsa-miR-548y, hsa-miR-203a-5p, hsa-miR-548e-5p, hsa-miR-585-3p, hsa-miR-378h, hsa-miR-1323, hsa-miR-183-5p, hsa-miR-200a-3p, hsa-miR-888-5p, hsa-miR-199a-3p+hsa-miR-199b-3p). Among these 13 miRNAs, one (i.e., hsa-miR-203a-5p) was also identified in a prior study, with significantly different expression levels between children with and without PPCS. Conclusion Our results from the longitudinal assessment of miRNAs indicate that the expression levels of 13 salivary miRNAs differ over time post-injury in concussed children with vs. without PPCS. Salivary miRNAs may be a promising biomarker for PPCS in children, although replication studies are needed.

Abstract
Objective: Characterize the working memory (WM) profile of children and youth who have experienced concussion by systematically synthesizing existing literature on the neuropsychological outcomes of these injuries.Methods: Implemented a peer-reviewed search strategy combining key concepts of concussion/mild traumatic brain injury (mTBI), WM, and pediatrics across MedLine, Embase, PsycINFO, and CINAHL. Included studies written in English with extractable results on a WM outcome measure in individuals aged 21 and under who experienced concussion. Applied narrative synthesis to identify trends in the literature. Assessed risk of bias and quality using the NHLBI's Quality Assessment of Observational Cohort and Cross-Sectional Studies.Results: 40 articles met inclusion criteria. 34/40 studies compared WM performance in children or youth with concussion to healthy controls, pre-injury performance, or normative values, of which 15 reported significantly lower WM performance in the concussion sample. Visual/spatial WM was more consistently impacted than verbal WM. Cognitive demanding dual-task conditions were also reliably impacted.Conclusion: Literature indicated that WM is vulnerable to negative outcomes following pediatric concussion, yet the nature of outcomes is variable. Clinicians and researchers should implement comprehensive and theoretically motivated WM assessments to better understand the WM components impacted by injury.

Abstract
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
Purpose College students with concussion are often ill-equipped to manage their health and learning needs, and college campuses are slow to react. We present the development of a peer mentoring program for college students with concussion: Success in College after Concussion with Effective Student Supports (SUCCESS), focusing on the process by which student needs and preferences drove development of the program for testing. Method Principles of person-centered design were used to guide program development, engaging stakeholders at each stage of development and resulting in the intervention package presented to student participants here. A series of interviews and focus groups with 11 students with concussion addressed student needs after concussion, student perceptions of the role of peers in recovery, and feedback on program development. Results Findings indicate students have limited knowledge about concussion, and concussion impacts extend beyond school, although students are most concerned about their studies. Students reported struggling to communicate with professors and find resources on campus to aid in their reentry to learning. Regarding peer mentoring, students report benefiting from hearing about other's successes and sharing personal narratives of injury and recovery. Students reported high acceptability of a peer mentoring program, both for psychosocial support and access to resources. Conclusions College students with concussion have unmet needs as they return to learn. The SUCCESS peer mentoring program is highly acceptable to students, who report that they would expect such a program to be engaging and to meet their needs. The program's impact on student academic and psychosocial outcomes should be investigated through comparative efficacy trials.

Abstract
Purpose People with traumatic brain injury (TBI) often struggle with complex reading, limiting participation in work and educational settings. This systematic review and meta-analysis examined studies of reading conducted with adolescents and adults with TBI to describe reading problems post TBI and investigate underlying factors for the effects of TBI on reading abilities. Method The search was conducted in EBSCO (including MEDLINE, PsycINFO, etc.), BIOSIS, ProQuest, and Web of Science. Empirical studies that used samples with a mean age greater than 10 years, reported injury characteristics, and investigated complex reading abilities (defined as greater than single-word reading) were eligible for this review. Study quality was evaluated using QualSyst. Study and sample characteristics, measures, and outcomes of interest were extracted and synthesized in the review. Studies that compared reading abilities between people with and without TBI were included in the meta-analysis. Results Twenty-four studies met inclusion criteria, six of which addressed reading in pediatric samples. Findings from heterogeneous samples supported the existence of reading deficits post TBI, including mild TBI. In studies of children, comprehension was examined most frequently, whereas reading speed was the focus of most adult studies. Oculomotor functions and processing speed were related to reading speed; cognitive functions, such as attention and memory, were associated with reading comprehension. Intervention studies were limited, but most reported positive effects. The meta-analysis confirmed the impact of TBI on reading with a large effect size (g = 1.23). Demographic, injury, and study variables did not moderate overall reading outcomes, but male sex was a significant moderator of impairment in reading speed. Discussion Global reading ability, including both comprehension and speed, is negatively impacted by TBI. Future research should continue to explore reading after TBI, including its underlying mechanisms, effects on complex reading activities such as inferencing, development of screening and assessment tools that address a range of functional reading needs, and efficacy of reading-related interventions.

Abstract
Mild traumatic brain injury is highly prevalent in paediatric populations, and can result in chronic physical, cognitive and emotional impairment, known as persistent post-concussive symptoms. Magnetoencephalography has been used to investigate neurophysiological dysregulation in mild traumatic brain injury in adults; however, whether neural dysrhythmia persists in chronic mild traumatic brain injury in children and adolescents is largely unknown. We predicted that children and adolescents would show similar dysfunction as adults, including pathological slow-wave oscillations and maladaptive, frequency-specific, alterations to neural connectivity. Using magnetoencephalography, we investigated regional oscillatory power and distributed brain-wide networks in a cross-sectional sample of children and adolescents in the chronic stages of mild traumatic brain injury. Additionally, we used a machine learning pipeline to identify the most relevant magnetoencephalography features for classifying mild traumatic brain injury and to test the relative classification performance of regional power versus functional coupling. Results revealed that the majority of participants with chronic mild traumatic brain injury reported persistent post-concussive symptoms. For neurophysiological imaging, we found increased regional power in the delta band in chronic mild traumatic brain injury, predominantly in bilateral occipital cortices and in the right inferior temporal gyrus. Those with chronic mild traumatic brain injury also showed dysregulated neuronal coupling, including decreased connectivity in the delta range, as well as hyper-connectivity in the theta, low gamma and high gamma bands, primarily involving frontal, temporal and occipital brain areas. Furthermore, our multivariate classification approach combined with functional connectivity data outperformed regional power in terms of between-group classification accuracy. For the first time, we establish that local and large-scale neural activity are altered in youth in the chronic phase of mild traumatic brain injury, with the majority presenting persistent post-concussive symptoms, and that dysregulated interregional neural communication is a reliable marker of lingering paediatric ‘mild’ traumatic brain injury.

Abstract
OBJECTIVE To examine the association of objectively measured, self-paced physical and cognitive activities across the first week postconcussion with symptom resolution in youth. SETTING Emergency department or concussion clinics. PARTICIPANTS Youth aged 11 to 17 years with physician-confirmed concussion. DESIGN Prospective cohort with repeated measures. MAIN MEASURES Days from injury to symptom resolution, based on daily ratings by youth on the Post-Concussive Symptom Scale. Physical and cognitive activities were assessed using an ActiGraph and a Narrative Clip, respectively. RESULTS A total of 83 youth participants were included (n = 54 [65%] males; mean age = 14.2 years, SD = 1.9). While self-paced daily physical and cognitive activities increased across the first week postinjury, daily postconcussion symptoms decreased. Increased daily step count was associated with an increased likelihood of early symptom resolution (hazard ratio [HR] = 1.17; 95% confidence interval [CI], 1.02-1.34). However, this association was not statistically significant after adjusting for acute postconcussion symptoms and other covariates. Greater school attendance time was associated with earlier symptom resolution (adjusted HR = 1.14; 95% CI, 1.02-1.27). CONCLUSION Self-paced physical and cognitive activities across the first week postinjury alone neither hastened nor prolonged concussion recovery. Youth with concussion may have some latitude to determine their activity levels.

Abstract
Between 2009 and 2014, all 50 states and the District of Columbia passed legislation to improve the recognition and management of youth concussed in sports. These laws can include requirements for concussion training for school athletic personnel, concussion education for children and their parents, return-to-play (RTP) procedures, and medical clearance to for RTP. Concussion can impact academic learning and performance in children and adolescents. Postconcussion academic accommodations during recovery can be an important component of secondary prevention for mitigating the sequalae of head injury. Few state youth concussion laws, however, include provision of postconcussion return-to-learn (RTL) accommodations and most of those that do address RTL apply to student athletes only. Concussions may occur in youth who are not participating in organised sports (eg, falls, traffic crashes) and thus may not be subjected to RTL accommodations, even if the state mandates such procedures for athletes. Low income and students of colour may be more likely to have non-sports concussions than their more affluent and white peers, thus potentially creating demographic disparities in the benefits of RTL procedures. State youth sports concussion laws should be revised so that they include RTL provisions that apply to all students, athletes and non-athletes alike.

Abstract
Concussion, or mild traumatic brain injury (mTBI), results from a force to the head and can cause acute physical, cognitive, and psychological symptoms. The majority of concussion symptoms will resolve within a month, but upward of a third of patients will have persistent, chronic symptoms. When these symptoms become chronic and persist beyond 1-3 months, this is termed post-concussion syndrome (PCS). Psychological changes associated with PCS may in part be due to a traumatic event and the injury itself and therefore post-traumatic stress reactions may contribute. In addition, alterations to daily life and alteration of lifestyle as a result of the injury can cause feelings of disconnection which in turn can feed anxiety and depression symptoms. A preinjury diagnosis or history of psychiatric or mood disorder, migraine, or family history of psychiatric illness is one the greatest risk factors for the development of PCS. It is recommended that evaluation of concussion and those with PCS take a multidisciplinary approach including evaluation by psychology, psychiatry, and/or neuropsychology. While most concussions do not require treatment, those with PCS will not likely see the resolution of their physical and psychological symptoms without intervention. Treatment is limited, but cognitive behavioral treatment has shown promise in the management of PCS symptoms. It is important to recognize the role psychology plays in the development and persistence of PCS and to recognize and seek collaborative care when treating these patients.

Abstract
OBJECTIVE The objective of this review was to identify associations between premorbid neuropsychological conditions and pediatric mild traumatic brain injury/concussion recovery time and symptom severity. INTRODUCTION There is a lack of evidence-based clinical guidelines for the care of children with a premorbid neuropsychological condition who have sustained a mild traumatic brain injury, also known as concussion. This necessitates inquiry for any associations that may exist, which may contribute to an enhanced understanding of injury recovery patterns. INCLUSION CRITERIA Participants included children ages six through 18 years with any diagnosed or self-reported premorbid neuropsychological condition(s) and mild traumatic brain injury/concussion. Participants with concomitant intracranial or extra-axial head injury found on diagnostic imaging were excluded. Outcomes for this review included recovery time or symptom(s) severity post-concussion. Studies considered for review were analytical observational studies, including retrospective, prospective, cross-sectional or longitudinal cohort studies or case-control studies, as well as descriptive observational study designs, including case series, individual case reports and descriptive cross-sectional studies. METHODS A comprehensive search was undertaken in January 2018 for both published and unpublished studies utilizing an a priori protocol. Major databases searched included CINAHL, Embase, PubMed, Psychology and Behavioral Sciences Collection and PsycINFO. Other sources searched for unpublished and gray literature included the Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, Google Scholar, ProQuest Dissertations and Theses Global: Sciences and Engineering Collection and MedNar. Additional searches of government websites and reports targeting healthcare or sports-related concussions included Australian Sports Commission, Canadian Institutes for Health Research, the National Health Service of the United Kingdom, the U.S. Department of Health and Human Services: Agency for Healthcare Research and Quality, and the U.S. Department of Health and Human Services: Centers for Disease Control and Prevention. Critical appraisal and data extraction were completed by two independent reviewers. Validation of methodologic quality was performed utilizing standardized tools from the Joanna Briggs Institute, and any disputes were resolved through discussion. Due to significant heterogeneity among studies, a meta-analysis could not be conducted. Therefore, extracted data are reported in a narrative synthesis. RESULTS A total of 12 studies (one analytical cross-sectional, two case-control and nine cohort) with 2,973 participants met inclusion criteria. Results of the findings among premorbid conditions varied. However, statistically significant associations with prolonged recovery or increased symptom severity were identified in children with pre-concussion histories of learning disabilities or poor academic achievement; anxiety, depression, mood disorders or other psychiatric illnesses; prior head injuries; somatization (in females); sleep disorders (in males); and the presence of multiple neuropsychological conditions. CONCLUSIONS Due to heterogeneity among studies and limitations of the review, findings suggest that clinicians providing post-concussive care may consider the presence of premorbid neuropsychological conditions, specifically learning disabilities or poor academic achievement; anxiety, depression, mood disorders or other psychiatric illnesses; prior head injuries; somatization; sleep disorders; or the presence of multiple neuropsychological conditions as potential contributors to prolonged recovery times or increased symptom severity in children and adolescents with mild traumatic brain injuries.

Abstract
Until recently, both the purpose of the biological need for sleep and the mechanism by which the central nervous system eliminated metabolic waste products were unknown. The glymphatic system is the recently discovered macroscopic waste clearance system for the CNS, which predominantly functions during sleep states. Important implications for the glymphatic system exist for a significant proportion of neurological disorders, including traumatic brain injury, epilepsy, stroke, migraine, and Alzheimer's disease. Within the limited amount of research pertaining to this novel system there exists controversy regarding several of the key structural and functional aspects of the glymphatic system. In this review we address evidence from both standpoints regarding the prominent debates surrounding the glymphatic system, including the functional differences in wakefulness vs. sleep, the role of glial aquaporin-4 water channels, and whether it reflects a convective flow or a passive diffusion process. The answers that underlie these questions will have crucial and distinct outcomes for the future of the glymphatic system and the disorders it has been implicated in. However, this review also summarizes the potential role of the glymphatic system in the development and progression of the aforementioned neurological disorders. Furthermore, the possible contribution of the orexinergic system to this relationship between the glymphatic system, sleep, and these neurological disorders is also explored. Overall, in order to develop and utilize therapeutic interventions centred around the glymphatic system we must first dedicate further investigation to elucidating these discrepancies and unanswered questions.

Abstract
BACKGROUND Persistent Sport-Related Post-Concussion Syndrome is often diagnosed with any type of prolonged PCS symptoms. However, there are not specific diagnostic criteria for PPCS such that misdiagnosis often occurs. Further, the signs and symptoms of PCS overlap with other common illnesses such as depression, anxiety, migraines, ADHD and others. Misdiagnosis may lead to less than efficacious treatment, resulting in prolonged symptoms. OBJECTIVE This article will review relevant evidence-based literature on PCS, pointing out the lack of a systemic diagnostic framework. It will also provide evidence that highlights the multiple conflicting findings in the literature. This article will posit the BioPsychoSocial framework as the best diagnostic framework for understanding the impact of concussions on the person and to generate individualized and personal interventions. METHODS A narrative review of sport concussion-related articles was conducted, after extensive searches of relevant and non-relevant literature by each author, as well as articles recommended by colleagues. Articles varied from American Academy of Neurology Class I to IV for evaluation and critique. Class IV articles were reviewed, as there is much public misconception regarding sport and other concussion treatment that needed identification and discussion. RESULTS Articles reviewed varied by quality of research design and methodology. Multiple symptoms, recovery patterns and rehabilitation treatment approaches are purported in the sport-related concussion literature. Current consensus data as well as the mixed and contradictory findings were explored. CONCLUSIONS Persistent Sport-Related Post-Concussion Syndrome is a topic of great interest to both professionals and the general public. There is much misunderstanding about the etiology, causation, diagnostic formulations, symptom presentation, prolonging factors and treatment involved in this syndrome. This article posits an individualized multi-system diagnostic formulation, examining all relevant factors, as generating the best interventions for neurorehabilitation of Persistent Sport-Related Post-Concussion Syndrome.

Epigenetic Effects on Pediatric Traumatic Brain Injury Recovery (EETR): An Observational, Prospective, Longitudinal Concurrent Cohort Study Protocol. Front Neurol 2020; 11:460.

Abstract
Introduction: Unexplained heterogeneity in outcomes following pediatric traumatic brain injury (TBI) is one of the most critical barriers to the development of effective prognostic tools and therapeutics. The addition of personal biological factors to our prediction models may account for a significant portion of unexplained variance and advance the field toward precision rehabilitation medicine. The overarching goal of the Epigenetic Effects on Pediatric Traumatic Brain Injury Recovery (EETR) study is to investigate an epigenetic biomarker involved in both childhood adversity and postinjury neuroplasticity to better understand heterogeneity in neurobehavioral outcomes following pediatric TBI. Our primary hypothesis is that childhood adversity will be associated with worse neurobehavioral recovery in part through an epigenetically mediated reduction in brain-derived neurotrophic factor (BDNF) expression in response to TBI. Methods and analysis: EETR is an observational, prospective, longitudinal concurrent cohort study of children aged 3-18 years with either TBI (n = 200) or orthopedic injury (n = 100), recruited from the UPMC Children's Hospital of Pittsburgh. Participants complete study visits acutely and at 6 and 12 months postinjury. Blood and saliva biosamples are collected at all time points-and cerebrospinal fluid (CSF) when available acutely-for epigenetic and proteomic analysis of BDNF. Additional measures assess injury characteristics, pre- and postinjury child neurobehavioral functioning, childhood adversity, and potential covariates/confounders. Recruitment began in July 2017 and will occur for ~6 years, with data collection complete by mid-2023. Analyses will characterize BDNF DNA methylation and protein levels over the recovery period and investigate this novel biomarker as a potential biological mechanism underlying the known association between childhood adversity and worse neurobehavioral outcomes following pediatric TBI. Ethics and dissemination: The study received ethics approval from the University of Pittsburgh Institutional Review Board. Participants and their parents provide informed consent/assent. Research findings will be disseminated via local and international conference presentations and manuscripts submitted to peer-reviewed journals. Trial Registration: The study is registered with clinicaltrials.org (ClinicalTrials.gov Identifier: NCT04186429).

Abstract
Mild traumatic brain injury (mTBI) is a debilitating but extremely common form of brain injury that affects a substantial number of people each year. mTBI is especially common in children and adolescents. Our understanding of mTBI pathophysiology is limited, and there is currently no accepted marker for disease severity. A potential marker for disease severity may be cerebrovascular dysfunction. Recent findings have implicated cerebrovascular alteration as an important component of mTBI and suggest it contributes to the development of persistent, long-term symptoms. In this paper, we conducted two studies to investigate whether mTBI affects venous drainage patterns in the central nervous system using alterations in the size of venous sinuses as a marker of changes in drainage. Using a closed head vertical weight-drop model and a lateral impact injury model of mTBI, we imaged and quantified the size of three major draining vessels in the adolescent rat brain using 9.4T MRI. Areas and volumes were quantified in the superior sagittal sinus and left and right transverse sinuses using images acquired from T2w MRI in one study and post-gadolinium T1w MRI in another. Our results indicated that the three venous sinuses were significantly larger in mTBI rats as compared to sham rats 1-day post injury but recovered to normal size 2 weeks after. Acutely enlarged sinuses post-mTBI may indicate abnormal venous drainage, and this could be suggestive of a cerebrovascular response to trauma.

Abstract
OBJECTIVES Whether mild traumatic brain injury (mTBI) sustained by children results in persistent or recurrent symptoms, over and above those experienced by children who solely sustain mild extracranial injuries, remains debated. The current prospective longitudinal case-controlled study aimed to examine the relative influence of injury and noninjury factors on symptoms in preschool and primary school-aged children who sustained an mTBI or mild extracranial injury at least 8 month earlier. METHODS Participants were 64 parents of children (31 mTBI, 33 trauma controls) who sustained injury between ages 2 and 12, whose postconcussive symptoms across the first 3-month postinjury have been previously described. The current study assessed postconcussive symptoms at 8 or more months postinjury (M = 24.3, SD = 8.4) and examined a range of injury and noninjury predictive factors. RESULTS At or beyond 8-month postinjury, symptom numbers in the mTBI group were comparable with those of the group who sustained mild extracranial injury. Educational attainment of parents (below or above high-school attainment level) was the only predictor of symptoms at follow-up, with preexisting learning difficulties approaching significance as a predictor. CONCLUSIONS While our earlier study found that mTBI was associated with symptoms at 3-month postinjury, follow-up at more than 8 months showed mTBI no longer predicted symptom reporting. While mTBI contributes significantly to the presence of symptoms in the first few months postinjury, researchers and healthcare practitioners in this field need to consider the potential impact of noninjury factors on persistent or recurrent symptoms after mTBI.

Abstract
The glymphatic system is the macroscopic waste clearance system for the central nervous system. Glymphatic dysfunction has been linked to several neurological conditions, including traumatic brain injury (TBI). Adolescents are at particularly high risk for experiencing a TBI, particularly mild TBI (mTBI) and repetitive mTBI (RmTBI); however, glymphatic clearance, and how it relates to behavioral outcomes, has not been investigated in this context. Therefore, this study examined glymphatic function in the adolescent brain following RmTBI. Female adolescent Sprague Dawley rats were subjected to either three mTBIs or sham injuries spaced three days apart. One-day after their final injury, the animals underwent a beam walking task to assess sensorimotor function, and contrast-enhanced MRI to visualize glymphatic clearance rate. Behavioural measures indicated that the RmTBI group displayed an increase in loss of consciousness as well as motor coordination and balance deficits consistent with our previous studies. The contrast-enhanced MRI results indicated that the female adolescent glymphatic system responds to RmTBI in a region-specific manner, wherein an increased influx but reduced efflux was observed throughout limbic structures (hypothalamus, hippocampus, and amygdala) and the olfactory bulb but neither the influx or efflux were altered in the cortical structures (primary motor cortex, insular cortex, and dorsolateral prefrontal cortex) examined. This may indicate a role for an impaired and/or inefficient glymphatic system in the limbic structures and cortical structures, respectively, in the development of post-concussive symptomology during adolescence.

Abstract
Objective: To investigate somatic and cognitive postconcussive symptoms (PCS) using the symptom evaluation subtest (cSCAT3-SE) of the Child Sports Concussion Assessment Tool 3 (Child SCAT) in tracking PCS up to 2 weeks postinjury.Methods: A total of 96 participants aged 5 to 12 years (Mage = 9.55, SD = 2.20) completed three assessment time points: 48 h postinjury (T0), 2 to 4 days postinjury (T1), and 2 weeks postinjury (T2). The Wilcoxon signed-rank test was used to analyze differences between cognitive and somatic symptoms over time, while the Friedman test was used to analyze differences within symptom type over time.Results: Cognitive PCS were found to be significantly higher than somatic PCS at all assessment time points and were also found to significantly decline from 4 days onwards postinjury; in contrast, somatic PCS significantly declined as early as 48 hpostinjury.Discussion: Differences between cognitive and somatic PCS emerge as early as a few days postinjury, with cognitive PCS being more persistent than somatic PCS across 2 weeks. Research in symptom-specific interventions may be of benefit in helping young children manage severe PCS as early as 2 weeks postinjury.

Abstract
While the physical and behavioral symptomologies associated with a single mild traumatic brain injury (mTBI) are typically transient, repetitive mTBIs (RmTBI) have been associated with persisting neurological deficits. Therefore, this study examined the progressive changes in behavior and the neuropathological outcomes associated with chronic RmTBI through adolescence and adulthood in male and female Sprague Dawley rats. Rats experienced 2 mTBIs/week for 15 weeks and were periodically tested for changes in motor behavior, cognitive function, emotional disturbances, and aggression. Brain tissue was examined for neuropathological changes in ventricle size and presentation of Iba1 and GFAP. We did not see progressively worse behavioral impairments with the accumulation of injuries or time, but did find evidence for neurological and functional change (motor disturbance, reduced exploration, reduced aggression, alteration in depressive-like behavior, deficits in short-term working memory). Neuropathological assessment of RmTBI animals identified an increase in ventricle size, prolonged changes in GFAP, and sex differences in Iba1, in the corpus callosum, thalamus, and medial prefrontal cortex. Telomere length reduced exponentially as the injury load increased. Overall, chronic RmTBI did not result in accumulating behavioral impairment, and there is a need to further investigate progressive behavioral changes associated with repeated injuries in adolescence and young adulthood.
