Functional recovery ten years after pediatric traumatic brain injury: outcomes and predictors

Family Health Care Needs in a Pediatric Population 6 Months After Moderate and Severe Physical Trauma

Background: Traumatic injury is a leading cause of death and disability in children and young adults. There is a lack of evidence-based literature and guidelines on supporting families after severe child injury. This study aimed to assess the family needs and factors associated with those needs. Methods: A prospective multicenter follow-up study conducted at two Norwegian trauma centers involving children (aged 0-18 years) who sustained a moderate or severe traumatic injury with a New Injury Severity Score > 9. Sociodemographic and injury variables were recorded at baseline. The Family Needs Questionnaire-Paediatric Version, ranging from one (not at all met) to five (completely met) was completed by parents to assess the family needs at the 6-month follow-up. Bivariate logistic regression analyses were conducted to identify the factors associated with the family needs at 6 months post-injury. Results: Of the 63 children included, 38 (68% boys) with a mean age of 9.9 years (SD = 5.8) were available for follow-up. At 6 months, 82% reported needs for health information with a mean score of 3.8 (SD = 1.0), and involvement with care with a mean of 3.7 (SD = 1.2). Additionally, 71% reported emotional support needs (mean score 2.6, SD = 1.3). A higher number of injuries and a lower age of the child were significantly associated with increased odds of having more family needs. Conclusions: After moderate to severe pediatric traumatic injury, families report a need for health information, involvement in care, and emotional support. Paying attention to the number of injuries and the child's age could help to identify families in need of information and support.

Long-term Participation and Functional Status in Children Who Experience Traumatic Brain Injury

OBJECTIVE

To evaluate the effect of child and family factors on children's participation outcomes 2 to 3 years following traumatic brain injury (TBI).

SETTING

Two level 1 pediatric trauma centers.

PARTICIPANTS

Children aged 0 to 15 years with TBI at all severity levels or an orthopedic injury.

DESIGN

Prospective cohort.

MAIN MEASURES

Caregivers completed the Child and Adolescent Scale of Participation (CASP) at 2- and 3-year follow-ups. The CASP was categorized as more than 90 or 90 or less on a 100-point scale, with 90 or less representing the 10th percentile and below in this sample. Modified Poisson regression models were used to describe relative risk of the CASP at 90 or less at 2 to 3 years postinjury, adjusting for preinjury family environment variables and injury group. A secondary analysis only included children who were 31 months or older at injury ( n = 441) to determine whether changes in functional outcome (Pediatric Injury Functional Outcome Scale, PIFOS) and executive functions (Behavior Rating Inventory of Executive Function, BRIEF) from preinjury to 1 year after injury predicted CASP scores at the 2- or 3-year follow-up.

RESULTS

Seventy-eight percent (596/769) of children who had a completed preinjury survey had a completed CASP. In the adjusted model, children with severe TBI had a nearly 3 times higher risk (RR = 2.90; 95% CI, 1.43-5.87) of reduced participation than children with an orthopedic injury. In the secondary analysis, lower functional skills (5-point increase in 1-year postinjury PIFOS score) (RR = 1.36; 95% CI, 1.18-1.57) and less favorable family function (RR = 1.46; 95% CI, 1.02-2.10) were associated with reduced participation in both girls and boys.

CONCLUSION

Participation in home, school, and community activities after TBI is related to multiple biopsychosocial factors. Participation-focused interventions are needed to reduce barriers to involvement and assist children and families to close the participation gap across settings.

Accuracy of Early Neuroprognostication in Pediatric Severe Traumatic Brain Injury

BACKGROUND

Children with severe traumatic brain injury (sTBI) are at risk for neurological sequelae impacting function. Clinicians are tasked with neuroprognostication to assist in decision-making. We describe a single-center study assessing clinicians' neuroprognostication accuracy.

METHODS

Clinicians of various specialties caring for children with sTBI were asked to predict their patients' functioning three to six months postinjury. Clinicians were asked to participate in the study if their patient had survived but not returned to baseline between day 4 and 7 postinjury. The outcome tool utilized was the functional status scale (FSS), ranging from 6 to 30 (best-worst function). Predicted scores were compared with actual scores three to six months postinjury. Lin concordance correlation coefficients were used to estimate agreement between predicted and actual FSS. Outcome was dichotomized as good (FSS 6 to 8) or poor (FSS ≥9). Positive and negative predictive values for poor outcome were calculated. Pessimistic prognostic prediction was defined as predicted worse outcome by ≥3 FSS points. Demographic and clinical variables were collected.

RESULTS

A total of 107 surveys were collected on 24 patients. Two children died. Fifteen children had complete (FSS = 6) or near-complete (FSS = 7) recovery. Mean predicted and actual FSS scores were 10.8 (S.D. 5.6) and 8.6 (S.D. 4.1), respectively. Predicted FSS scores were higher than actual scores (P < 0.001). Eight children had collective pessimistic prognostic prediction.

CONCLUSIONS

Clinicians predicted worse functional outcomes, despite high percentage of patients with near-normal function at follow-up clinic. Certain patient and provider factors were noted to impact accuracy and need to be studied in larger cohorts.

Behaviour outcomes three months after mild TBI in preschool children

This study examined parents' report of behaviour in preschoolers after a mild traumatic brain injury (mTBI), compared the proportion of preschoolers with elevated behaviour ratings between the mTBI and limb injury (LI) groups, and explored injury, premorbid child, and parent variables that may be associated with parents' report of behaviour at three months post-injury. Children aged 2-5 years with a mTBI (n = 13) or mild LI (n = 6) were recruited from the emergency department. Behaviour was assessed using the Child Behaviour Checklist. Preliminary findings showed that post-injury behaviour ratings remained in the normal range. The mTBI group had higher scores than the LI group at three months post-injury in terms of sleep; however, this may have been pre-existing. Two children with mTBI received borderline-clinically significant ratings on diagnostic-level anxiety problems at the three-month follow-up, while none of the limb-injured controls obtained elevated behaviour ratings. Parent-rated post-injury behaviour was significantly associated with premorbid child functioning and parental stress, which needs to be explored in greater detail using larger preschool mTBI samples.

Is Pre-Injury Socioeconomic Status Associated With Outcomes in Patients With Traumatic Brain Injury? A Systematic Review

While socioeconomic status (SES) is associated with a variety of health outcomes, the literature on the association between SES and traumatic brain injury (TBI) outcomes has not been formally summarized. This study aims to review existing literature to ascertain whether patients with low SES pre-injury have worse clinical outcomes after TBI compared with those with high SES, in high-income countries. A systematic search was conducted using the MEDLINE, Embase, and PsychINFO databases. Observational studies addressing the association between SES and TBI outcomes (mortality, functional, cognitive, and vocational outcomes) were included (published from 2000, written in English). Both pediatric and adult TBI groups were included. Thirty-two studies met the inclusion criteria. Measures of SES varied across studies. Mortality was assessed in seven studies; five reported an association between low SES and higher mortality. Five of eight studies showed an association between low SES and worse functional outcomes; results for cognitive (n = 13) and vocational outcomes (n = 10) were mixed. The results of this review suggest that SES is a variable of interest in the context of TBI outcomes and should be assessed at time of admission to assist in social work discharge planning and early mobilization of available community resources. Further work is required to better understand the impact of SES on TBI outcomes.

Family involvement in rehabilitation programmes for children and adolescents with acquired brain injury: A scoping literature review

Paediatric acquired brain injury (ABI) can adversely impact families, and it is widely accepted that families should be involved in the rehabilitation of children/adolescents with ABI. However, there is limited guidance about how to best involve families in paediatric ABI rehabilitation. Several programmes involving the families of children/adolescents with ABI have been developed, but there are no published reviews outlining their characteristics. This scoping literature review aimed to synthesize information about these programmes and develop an understanding of how families are involved in them. Four databases were systematically searched to identify sources of evidence that described programmes in paediatric ABI rehabilitation that involve family members. One hundred and eight sources of evidence describing 42 programmes were included. Programmes were categorized as: service coordination (n = 11), psychosocial (n = 17), support groups (n = 4), training/instruction (n = 9), and education (n = 1). Families' involvement in these programmes varied across programme development, delivery, and evaluation stages. The findings of this scoping literature review outline how families can be involved in paediatric ABI rehabilitation. While this review outlines many approaches to supporting families, it also highlights the need for models of family-centred care to better articulate how clinicians and services can involve families in paediatric ABI rehabilitation.

Nature and correlates of self-esteem in young adult survivors of childhood traumatic brain injury

Despite growing research linking childhood traumatic brain injury (TBI) with reduced wellbeing, self-esteem, and psycho-social health, very few studies have examined self-esteem and its correlates in young adult survivors of childhood TBI. This very-long-term follow-up study evaluated self-esteem in 29 young adults with a history of childhood TBI (M time since injury = 13.84 years; SD = 0.74), and 10 typically developing controls (TDCs). All participants were originally recruited into a larger, longitudinal case-control study between 2007 and 2010. In the current follow-up study, both groups completed well-validated measures of self-esteem and mental health in young adulthood. Although group means for self-esteem did not significantly differ between TBI and TDC groups, a higher proportion of TBI participants rated their self-esteem in the clinical range (TBI group = 17%; TDC group = 0%). While self-esteem was not significantly associated with injury or pre-injury child or family characteristics, lower self-esteem was significantly correlated with greater concurrent feelings of loneliness (p = 0.007) and higher concurrent mood symptoms (p < 0.001).Our results suggest that social isolation and low mood may represent meaningful targets for psycho-social interventions to address poor self-worth in young adults with a history of childhood TBI.

Unmet health care needs over the first 2 years after pediatric traumatic brain injury

AIM

Few studies have addressed how children and adolescents with traumatic brain injuries (TBIs) access health care and educational services. This study aimed to investigate the course of symptoms during the first two years after TBI, whether symptoms implied a need for health care and/or educational services, and the extent of unmet needs. The association between unmet needs and health-related quality of life was also explored.

METHODS

This prospective cohort study was conducted at Oslo University Hospital, Norway, from 2015 to 2018. Forty-nine patients aged 1-15 years hospitalized due to TBI were included and followed for 24 months. Registration of symptoms and identification of unmet needs was based on clinical assessment, self-reports and interviews with patients and parents during the acute phase and at 6 and 24 months postinjury.

RESULTS

Twenty-five percent of the sample presented with unmet needs at 24 months. Compared to the group with no needs and met needs, these patients reported lasting cognitive and emotional symptoms affecting school and social interaction and scored lower on health-related quality of life.

CONCLUSION

Pediatric patients with TBI may have long-term symptom burden affecting school and social functioning, leading to unmet needs if targeted services are not provided.

Differences between parent- and teacher-reported executive functioning behaviors after traumatic injuries

Deficits in executive functioning (EF) behaviors are very common following pediatric traumatic brain injury (TBI) and can linger well after acute injury recovery. Raters from multiple settings provide information that may not be appreciated otherwise. We examined differences between parent and teacher ratings of EF using data examining longitudinal outcomes following pediatric TBI in comparison to orthopedic injury (OI). We used linear mixed models to determine the association of rater type and injury type with scores on the Behavior Rating Inventory of Executive Functioning (BRIEF). After controlling for demographic variables, rater type and injury type accounted for a small but significant proportion of the variance in EF. Teachers' ratings on the BRIEF were significantly higher than parent ratings for global EF and metacognition, but not for behavior regulation, regardless of injury type, indicating greater EF concerns. All BRIEF ratings, whether from teachers or parents, were higher for children with TBI than for those with OI. Results suggest that parents and teachers provide unique information regarding EF following traumatic injuries and that obtaining ratings from persons who observe children at school as well as at home can result in a better understanding of situation-specific variability in outcomes.

Puberty, brain network connectivity and neuropsychiatric outcomes following pediatric traumatic brain injury in females: A research protocol

BACKGROUND

Examining the role of sex on recovery from pediatric TBI (pTBI) is a complex task, specifically when referring to injuries occurring during critical developmental and maturation periods. The effect of sex hormones on neurological and neuropsychiatric outcomes has been studied among adult TBI females, but not in children. During development, puberty is considered a key milestone accompanied by changes in physical growth, neuronal maturation, sex hormones, and psychological symptoms. Following pTBI, such changes might have a significant effect on brain re-organization and on long-term neuropsychiatric outcomes. While hormonal dysfunction is a common consequence following pTBI, only few studies have systematically evaluated hormonal changes following pTBI.

AIMS

To describe a multimodal protocol aimed to examine the effect of puberty on brain connectivity and long-term neuropsychiatric outcomes following TBI in female girls and adolescents.

METHODS

A case-control longitudinal prospective design will be used. 120 female participants aged 9 to 16 years (N = 60 per group) will be recruited. In the acute phase (T0-1 month), participants will undergo an MRI protocol for brain connectivity, as well as a clinical evaluation for puberty stage and hormonal levels. In the chronic phase (T1-18-24 months), participants will complete a neuropsychiatric assessment in addition to the MRI and puberty evaluations. Hormonal levels will be monitored at T0 and T1. A moderation-mediation model will be used to examine the moderating effects of puberty on the association between pTBI and neuropsychiatric symptoms in female girls and adolescents, through the mediating effect of brain network connectivity.

SIGNIFICANCE

This study will highlight sex-specific factors related to outcomes among females following pTBI and enhance our understanding of the unique challenges they face. Such information has a substantial potential to guide future directions for research, policy and practice.

Rehabilitation models of care for children and youth with traumatic brain and/or spinal cord injuries: A focus on service structure, service organization, and the barriers and facilitators of rehabilitation service provision

To understand the systems underlying current rehabilitation models of care used with children and youth (0-21years) who sustain traumatic brain and/or spinal cord injuries. This study gathered qualitative data on service structures, service organization, and the barriers and facilitators of service provision in selected medical rehabilitation service(s) (MRS) and community-based rehabilitation service(s) (CBRS). Informants from 11 rehabilitation services were interviewed using a semi-structured interview guide. Interviews were analysed in NVivo using content analysis method. Experiences shared by the service representatives indicated that most services supported children and youth with brain injury, with a limited number also specializing in spinal cord injuries. MRS often delivered care in inpatient or outpatient settings, while CBRS offered home/community-based services. Care planning often started either prior to or shortly after admission from acute care settings, using either multidisciplinary or interdisciplinary teamwork models. Strengths of the services included innovation and provision of family-centred care; while challenges experienced included difficulty translating evidence into practice and poor team communication. Models of care were similar across services, with a focus on providing family-centred care. Several shared challenges were described, and service representatives expressed interest in forming partnerships and collaborations to address these challenges through innovative initiatives.

Pediatric Traumatic Brain Injury: Impact on the Developing Brain

Traumatic brain injury (TBI) is a serious public health concern impacting millions of children and adolescents each year. Experiencing a brain injury during key critical periods of brain development can affect the normal formation of brain networks that are responsible for a range of complex neurocognitive outcomes. In addition, there are multiple pre- and postinjury factors that influence the trajectory of recovery and outcomes. In this review, we will focus on the current state of the literature within pediatric TBI; systematically review the available research on developmental aspects of TBI in children, focusing on the pathophysiology of the injury and its impact on the developing brain; and highlight knowledge gaps for further exploration.

Regional Cortical Thickness Correlates of Intellectual Abilities Differ in Children With Traumatic Brain Injury Versus Those With Orthopedic Injury in the Chronic Post-Injury Phase

A decline in intellectual functioning (intelligence quotient [IQ]) is often observed following more severe forms of traumatic brain injury (TBI) and is a useful index for long-term outcome. Identifying brain correlates of IQ can serve to inform developmental trajectories of behavior in this population. Using magnetic resonance imaging (MRI), we examined the relationship between intellectual abilities and patterns of cortical thickness in children with a history of TBI or with orthopedic injury (OI) in the chronic phase of injury recovery. Participants were 47 children with OI and 58 children with TBI, with TBI severity ranging from complicated-mild to severe. Ages ranged from 8 to 14 years old, with an average age of 10.47 years, and an injury-to-test range of ∼1-5 years. The groups did not differ in age or sex. The intellectual ability estimate (full-scale [FS]IQ-2) was derived from a two-form (Vocabulary and Matrix Reasoning subtests) Wechsler Abbreviated Scale of Intelligence (WASI). MRI data were processed using the FreeSurfer toolkit and harmonized across data collection sites using neuroComBat procedures, while holding demographic features (i.e., sex, socioeconomic status [SES]), TBI status, and FSIQ-2 constant. Separate general linear models per group (TBI and OI) and a single interaction model with all participants were conducted with all significant results withstanding correction for multiple comparisons via permutation testing. Intellectual ability was higher (p < 0.001) in the OI group (FSIQ-2 = 110.81) than in the TBI group (FSIQ-2 = 99.81). In children with OI, bi-hemispheric regions, including the right pre-central gyrus and precuneus and bilateral inferior temporal and left occipital areas were related to IQ, such that higher IQ was associated with thicker cortex in these regions. In contrast, only cortical thickness in the right pre-central gyrus and bilateral cuneus positively related to IQ in children with TBI. Significant interaction effects were found in the bilateral temporal, parietal, and occipital lobes and left frontal regions, indicating that the relationship between IQ and cortical thickness differed between groups in these regions. Changes in cortical associations with IQ after TBI may reflect direct injury effects and/or adaptation in cortical structure and intellectual functioning, particularly in the bilateral posterior parietal and inferior temporal regions. This suggests that the substrates of intellectual ability are particularly susceptible to acquired injury in the integrative association cortex. Longitudinal work is needed to account for normal developmental changes and to investigate how cortical thickness and intellectual functioning and their association change over time following TBI. Improved understanding of how TBI-related cortical thickness alterations relate to cognitive outcome could lead to improved predictions of outcome following brain injury.

Memory in Social Interactions: The Effects of Introspection on Destination Memory in Traumatic Brain Injury

Destination memory, which is the ability to remember to whom one has sent information, is intimately associated with social cognition. We assessed whether processing attributes of destinations would improve destination memory in patients with traumatic brain injury (TBI). In this cross-sectional study, we tested the destination memory of 24 patients with TBI and 25 control participants in two conditions. On the first one (control condition), we invited participants to tell proverbs to celebrities' faces in order to decide, on a subsequent recognition test, whether they previously told that proverb to that celebrity or not. On the second condition (experimental introspection condition), the same procedures were repeated. However, after telling the proverbs, we invited participants to introspect about what the destination might believe about the proverbs (e.g., "What do you think that the celebrities would think about the proverbs?"). Group comparisons demonstrated better destination memory after the introspection than when no introspection was implemented in control participants, but there were no significant differences between the two conditions in patients with TBI. However, analyses of individual profiles demonstrated that more than half (n = 13) of the patients with TBI demonstrated better destination memory after introspection. While these results demonstrate a beneficial effect of introspection on destination memory for some cases of patients with TBI, more research is needed to reveal how introspection may influence patients' memory in social interactions.

A Multidimensional Approach to Assessing Factors Impacting Health-Related Quality of Life after Pediatric Traumatic Brain Injury

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.

The Role of Speech-Language Pathologists in Expanding Delivery of Teen Online Problem Solving for Adolescents With Acquired Brain Injury: A Quality Improvement Project

PURPOSE

Teen Online Problem Solving (TOPS) is an evidence-based teletherapy program designed to promote neurocognitive, behavioral, and psychosocial recovery following brain injury through family-centered training. To date, TOPS has been primarily administered by neuropsychologists and clinical psychologists. This clinical focus article discusses a quality improvement project to adapt the TOPS training and manual for use by speech-language pathologists (SLPs) and reports feedback from SLPs following TOPS training and after delivering the program with adolescents who experienced neurological insults.

METHOD

SLPs were invited to participate in TOPS training. Trainees were asked to complete posttraining surveys, active therapist questionnaires, and follow-up surveys directed to SLPs who had completed the intervention with at least one patient.

RESULTS

To date, a total of 38 SLPs completed TOPS training, 13 have implemented TOPS with at least one adolescent. Eight SLPs and 16 psychologists/trainees responded to follow-up surveys to share their perspectives on the program. Perceptions of clinicians delivering the program did not differ significantly in most respects. SLPs rated the ease of understanding nonverbal communication higher than psychologists. Seven SLPs responded to an SLP-specific survey about their experiences administering TOPS, noting a range of advantages and some limitations in their open-ended responses.

CONCLUSION

Training SLPs to deliver TOPS has the potential to increase service provision to adolescents with acquired brain injury who have cognitive communication difficulties and their families.

Perspectives on care coordination for youth with TBI: Moving forward to provide better care

BACKGROUND

Care coordination aligns services and optimizes outcomes for children with traumatic brain injury (TBI), yet numerous obstacles can impede effective care coordination following a TBI.

OBJECTIVE

The goal of this work is to identify barriers and facilitators to care coordination from the perspective of individuals who care for young people impacted by TBI (e.g., medical providers, educators, caregivers).

METHODS

Twenty-one care providers participated in semi-structured interviews to gather their perspectives on systems of care coordination for youth with TBI and potential areas for improvement. Using reflexive thematic analysis, researchers identified key themes across interviews.

RESULTS

Three themes were identified: 1) gaps in knowledge; 2) poor collaboration and communication between systems and care providers; and 3) inadequate legislative and policy frameworks that fund and support pediatric TBI. Across themes, participants shared their experiences and ideas to improve each of these areas.

CONCLUSION

A structured, consistent, and coordinated system of care for pediatric TBI is critical to ensure optimal outcomes. Protocols that emphasize intentional and productive collaboration between healthcare settings and schools and education for all care providers are cornerstones in improving outcomes for children. Top-down action that develops policy and funding initiatives is needed to ensure equitable, consistent access to appropriate healthcare and educational supports.

A single mild juvenile TBI in male mice leads to regional brain tissue abnormalities at 12 months of age that correlate with cognitive impairment at the middle age

Traumatic brain injury (TBI) has the highest incidence amongst the pediatric population and its mild severity represents the most frequent cases. Moderate and severe injuries as well as repetitive mild TBI result in lasting morbidity. However, whether a single mild TBI sustained during childhood can produce long-lasting modifications within the brain is still debated. We aimed to assess the consequences of a single juvenile mild TBI (jmTBI) at 12 months post-injury in a mouse model. Non-invasive diffusion tensor imaging (DTI) revealed significant microstructural alterations in the hippocampus and the in the substantia innominata/nucleus basalis (SI/NB), structures known to be involved in spatial learning and memory. DTI changes paralled neuronal loss, increased astrocytic AQP4 and microglial activation in the hippocampus. In contrast, decreased astrocytic AQP4 expression and microglia activation were observed in SI/NB. Spatial learning and memory were impaired and correlated with alterations in DTI-derived derived fractional ansiotropy (FA) and axial diffusivity (AD). This study found that a single juvenile mild TBI leads to significant region-specific DTI microstructural alterations, distant from the site of impact, that correlated with cognitive discriminative novel object testing and spatial memory impairments at 12 months after a single concussive injury. Our findings suggest that exposure to jmTBI leads to a chronic abnormality, which confirms the need for continued monitoring of symptoms and the development of long-term treatment strategies to intervene in children with concussions.

The Australian and New Zealand brain injury lifespan cohort protocol: Leveraging common data elements to characterise longitudinal outcome and recovery

INTRODUCTION

Cognitive, behavioural, academic, mental health and social impairments are common following paediatric traumatic brain injury (TBI). However, studies are often reliant on small samples of children drawn from narrow age bands, and employ highly variable methodologies, which make it challenging to generalise existing research findings and understand the lifetime history of TBI.

METHOD AND ANALYSIS

This study will synthesise common data sets from national (Victoria, New South Wales, Queensland) and international (New Zealand) collaborators, such that common data elements from multiple cohorts recruited from these four sites will be extracted and harmonised. Participant-level harmonised data will then be pooled to create a single integrated data set of participants including common cognitive, social, academic and mental health outcome variables. The large sample size (n=1816), consisting of participants with mild, moderate and severe TBI, will provide statistical power to answer important questions that cannot be addressed by small, individual cohorts. Complex statistical modelling, such as generalised estimation equation, multilevel and latent growth models, will be conducted.

ETHICS AND DISSEMINATION

Ethics approval was granted by the Human Research Ethics Committee (HREC) of the Royal Children's Hospital (RCH), Melbourne (HREC Reference Number 2019.168). The approved study protocol will be used for all study-related procedures. Findings will be translated into clinical practice, inform policy decisions, guide the appropriate allocation of limited healthcare resources and support the implementation of individualised care.

Variability Across Caregiver and Performance-Based Measures of Executive Functioning in an Acute Pediatric Neurocritical Care Population

Youth admitted to the pediatric intensive care unit (PICU) for traumatic brain injury (TBI) commonly struggle with long-term residual effects in the domains of physical, cognitive, emotional, and psychosocial/family functioning. In the cognitive domain, executive functioning (EF) deficits are often observed. The Behavior Rating Inventory of Executive Functioning, Second Edition (BRIEF-2) is a parent/caregiver-completed measure that is regularly utilized to assess caregivers' perspectives of daily EF abilities. Using parent/caregiver-completed measures like the BRIEF-2 in isolation as outcome measures for capturing symptom presence and severity might be problematic given that caregiver ratings are vulnerable to influence from external factors. As such, this study aimed to investigate the association between the BRIEF-2 and performance-based measures of EF in youth during the acute recovery period post-PICU admission for TBI. A secondary aim was to explore associations among potential confounding factors, including family-level distress, injury severity, and the impact of pre-existing neurodevelopmental conditions. Participants included 65 youths, 8-19 years of age, admitted to the PICU for TBI, who survived hospital discharge and were referred for follow-up care. Non-significant correlations were found between BRIEF-2 outcomes and performance-based measures of EF. Measures of injury severity were strongly correlated with scores from performance-based EF measures, but not BRIEF-2. Parent/caregiver-reported measures of their own health-related quality of life were related to caregiver responses on the BRIEF-2. Results demonstrate the differences captured by performance-based versus caregiver-report measures of EF, and also highlight the importance of considering other morbidities related to PICU admission.

Effects of Pediatric Traumatic Brain Injury on Verbal IQ: A Systematic Review and Meta-Analysis

OBJECTIVES

To examine the effects of pediatric traumatic brain injury (TBI) on verbal IQ by severity and over time.

METHODS

A systematic review and subsequent meta-analysis of verbal IQ by TBI severity were conducted using a random effects model. Subgroup analysis included two epochs of time (e.g., <12 months postinjury and ≥12 months postinjury).

RESULTS

Nineteen articles met inclusion criteria after an extensive literature search in MEDLINE, PsycInfo, Embase, and CINAHL. Meta-analysis revealed negative effects of injury across severities for verbal IQ and at both time epochs except for mild TBI < 12 months postinjury. Statistical heterogeneity (i.e., between-study variability) stemmed from studies with inconsistent classification of mild TBI, small sample sizes, and in studies of mixed TBI severities, although not significant. Risk of bias on estimated effects was generally low (k = 15) except for studies with confounding bias (e.g., lack of group matching by socio-demographics; k = 2) and measurement bias (e.g., outdated measure at time of original study, translated measure; k = 2).

CONCLUSIONS

Children with TBI demonstrate long-term impairment in verbal IQ, regardless of severity. Future studies are encouraged to include scores from subtests within verbal IQ (e.g., vocabulary, similarities, comprehension) in addition to functional language measures (e.g., narrative discourse, reading comprehension, verbal reasoning) to elucidate higher-level language difficulties experienced in this population.

Factors associated with poor neurological outcome in children after abusive head trauma: A multicenter retrospective study

BACKGROUND

Abusive Head Trauma (AHT) remains the leading cause of brain injury in infants.

OBJECTIVE

This study aims to describe a cohort of patients with AHT and identify early risk factors associated with poor neurological outcome.

PARTICIPANTS AND SETTING

Children under one year old admitted to a Pediatric Intensive Care Unit (PICU) with a suspected or confirmed diagnosis of AHT were included. Neurological outcome was assessed by the Pediatric Overall Performance Category score (POPC) at discharge from the hospital and at two years of follow-up.

METHODS

A multicentre retrospective study was conducted over 8 years (from January 2012 to December 2020).

RESULTS

A total of 117 patients (mean age 4.3 (+/- 2.5) months, 61 % boys) from three PICUs were included. A total of 99 (85 %) patients completed a 2-year follow-up. Sixty-one (52 %) and 47 (40 %) children with AHT had a POPC (pediatric overall performance category) score ≥ 2 at discharge from ICU and discharge from hospital, respectively (meaning they had at least a moderate disability). Fifty-one (44 %) had a POPC score ≥ 2 at 2-year follow-up, including 19 patients (19 %) with severe disabilities. The main neurological disabilities were neurodevelopmental (n = 38, 35 %), hyperactivity disorder (n = 36, 33 %) and epilepsy (n = 34, 31 %). After analysis according to the hierarchical model, the occurrence of a cardiorespiratory arrest and a low Glasgow Coma Score at admission stand out as factors of poor neurological outcome.

CONCLUSION

This study highlights the wide range of neurological disabilities in children with AHT. Early and multidisciplinary follow-up is crucial to limit the impact of neurological disability.

The Impact of Preinjury and Secondary Attention-Deficit/Hyperactivity Disorder on Outcomes After Pediatric Traumatic Brain Injury

OBJECTIVE

The objective of this study was to examine the impact of preinjury attention-deficit/hyperactivity disorder (PADHD) and secondary ADHD (SADHD) on outcomes after pediatric traumatic brain injury (TBI).

METHODS

Two hundred eighty-four individuals aged 11 to 18 years hospitalized overnight for a moderate-to-severe TBI were included in this study. Parents completed measures of child behavior and functioning and their own functioning. Linear models examined the effect of ADHD status (PADHD vs SADHD vs no ADHD) on the child's executive functioning (EF), social competence, and functional impairment, and parental depression and distress.

RESULTS

ADHD status had a significant effect on EF [F(2,269] = 9.19, p = 0.0001), social competence (F[2,263] = 32.28, p < 0.0001), functional impairment (F[2,269] = 16.82, p < 0.0001), parental depression (F[2,263] = 5.53, p = 0.005), and parental distress (F[2,259] = 3.57, p = 0.03). PADHD and SADHD groups had greater EF deficits, poorer social competence, and greater functional impairment than the no ADHD group. The SADHD group had greater levels of parental depression than the no ADHD and PADHD groups, and the SADHD group had higher parental distress than the no ADHD group.

CONCLUSION

The results highlight the importance of early identification and management of ADHD symptoms after injury to mitigate downstream functional problems. Supporting parents managing new-onset ADHD symptoms may also be important.

A new model to guide identity-focused multidisciplinary rehabilitation for children and young people following acquired brain injury: I-FoRM

A complexity of biological, psychological, environmental and systemic factors influences a child's adaption after acquired brain injury (ABI), all of which transform as the child matures. Multidisciplinary rehabilitation teams are challenged by balancing family system needs and the child's needs, whilst promoting the child's functional skills in difficult or unappealing tasks. This paper presents the conceptual basis for a model for use in childhood ABI neurorehabilitation to address these challenges. A non-systematic narrative review of literature pertinent to integrated neurorehabilitation of pediatric ABI was conducted. Contemporary models of adult and pediatric psychosocial adaptation involving identity following ABI were reviewed. Key findings were then synthesized with models of pediatric resilience and self-concept development. The resulting model describes a cyclical adaptation process whereby the child learns experientially about their self and their world after ABI. Processes of identity development play a central role - particularly emotive processes of self-evaluation - by influencing the child's motivation for participation, tolerance for challenge, self-regulation and emerging self-awareness. The model directs clinicians to use the psychosocial processes of identity development to enhance the child's willingness and capacity to engage in the daily challenges of rehabilitation. Further systematic development and evaluation of the model is needed.

Perfectionism, Big Five and biopsychosocial functioning among parents of children with and without acquired brain injury (ABI)

BACKGROUND AND OBJECTIVE

Personality factors are often investigated in the context of parenting but are rarely studied in relation to coping with child disabilities like pediatric acquired brain injury (pABI). This study (1) compares Biopsychosocial functioning (BPSF), Big Five personality traits, and dimensions of perfectionism of parents of children with and without pABI, and (2) examines the role personality factors play in parental BPSF in each group.

METHOD

57 parents of children who sustained a significant pABI and 50 parents of typically developing children participated in this cross-sectional study. Parents completed scales measuring Multidimensional Perfectionism, Big Five inventory, and BPSF.

RESULTS

Among the pABI group, multivariate analysis indicated significantly poorer BPSF, higher levels of neuroticism, socially prescribed perfectionism, and lower levels of openness, than controls. Regression analysis showed that personality explained 60.5% of the variance in parental BPSF post pABI. In both samples, neuroticism and socially prescribed perfectionism appeared as two prominent personality factors with a significant negative effect on parental BPSF, while self-perfectionism appeared prominent only in the pABI group, indicating a significant positive effect.

IMPLICATIONS

pABI may result in changes to parents` personality. Personality characteristics significantly contribute to parental BPSF post-injury and should be addressed in clinical practice.

Predictors of Functional School Outcome in Children With Pediatric Acquired Brain Injury

Objective

Among the variety of domains that may be impacted after pediatric acquired brain injury (pABI) are functional school outcomes. The purpose of this study was to identify demographic, medical, and psychological factors associated with impairments in functional school outcomes, defined as school absence, need of educational and psychological services, quality of life (QoL) in the school setting, and academic performance in children with pABI, with a specific emphasis on the significance of fatigue.

Materials and Method

We used baseline data from a randomized controlled trial. The sample consisted of seventy-six children aged 10 to 17 (M = 13 yrs) with pABI in the chronic phase (>1 year). All completed assessments of school-related QoL, academic performance, global functioning, fatigue, IQ, behavioral problems, and executive function.

Results

Fatigue, IQ, global functioning, behavioral problems, and sex emerged as potential predictors for functional school outcomes. Of note, overall fatigue emerged as the strongest potential predictor for parent-reported QoL in school (β = 0.548; p < 0.001) and self-reported QoL in school (β = 0.532; p < 0.001).

Conclusions

Following pABI, specific psychological, medical, and demographic factors are associated with functional school outcomes. Neither of the injury-related variables age at insult and time since insult were associated with functional school outcomes. Overall, our findings may suggest that a reintroduction to school with personalized accommodations tailored to the child's specific function and symptoms, such as fatigue, is recommended.

Glucocorticoid Receptor Overexpression in the Dorsal Hippocampus Attenuates Spatial Learning and Synaptic Plasticity Deficits Following Pediatric Traumatic Brain Injury

Traumatic brain injury (TBI) in children younger than 4 years old leads to long-term deficits in cognitive and learning abilities that can persist or even worsen as children age into adolescence. In this study, the role of glucocorticoid receptor (GR) function in the dorsal hippocampus (DH) in hippocampal-dependent cognitive function and synaptic plasticity were assessed following injury to the 11-day-old rat. Brain injury produced significant impairments in spatial learning and memory in the Morris water maze in male and female rats at 1-month post-injury (adolescence) which was accompanied by impairments in induction and maintenance of long-term potentiation (LTP) in the CA1 region of the DH. Brain injury resulted in a significant decrease in the expression of the glucocorticoid-inducible gene, serum- and glucocorticoid-kinase 1 (sgk1), suggestive of an impairment in GR transcriptional activity within the hippocampus. Lentiviral transfection of the human GR (hGR) in the DH improved spatial learning and memory in the Morris water maze and attenuated LTP deficits following TBI. GR overexpression in the DH was also associated with a significant increase in the mRNA expression levels of sgk1, and the glutamate receptor subunits GluA1 and GluA2 within the hippocampus. Overall, these findings support an important role of dorsal hippocampal GR function in learning and memory deficits following pediatric TBI and suggest that these effects may be related to the regulation of glutamate receptor subunit expression in the DH.

Global and domain-specific self-esteem after pediatric traumatic brain injury: Contribution of injury characteristics and parent mental health

This prospective, longitudinal case-control study examined global and domain-specific aspects of self-esteem 6-months following pediatric traumatic brain injury (TBI) and evaluated the contribution of injury-related factors and parent mental health to child self-esteem. Participants included 103 children with mild-severe TBI representing consecutive admissions to the emergency department of the Royal Children's Hospital, Melbourne, Australia. Forty-three age-and-sex matched typically developing controls were recruited for comparison. Information regarding injury characteristics including age at injury and clinical indicators of TBI severity were collected for participants at recruitment, with research magnetic resonance imaging conducted 2-8 weeks later. At 6 months post-injury, children rated their global and domain-specific self-esteem (Harter Self-Perception Profile for Children), and ratings of parent mental health were collected (General Health Questionnaire). Self-esteem for behavioural and academic domains was significantly poorer for children with TBI relative to TD children. In the TBI group, higher child-rated scores of global and domain-specific aspects of self-esteem were associated with more severe TBI, presence of frontal neuropathology, younger age at injury, and lower parental symptoms of anxiety/insomnia. Given the psychological status of parents represents a potentially modifiable risk factor, it may form the target of clinical interventions designed to bolster child self-esteem following pediatric TBI.

A scoping review to inform care coordination strategies for youth with traumatic brain injuries: Care coordination personnel

Introduction & Importance:

Effective, patient-centered care coordination has been shown to improve outcomes for children with special healthcare needs (CSHCN), who often have complex, long-term involvement with multiple service providers. Traumatic brain injury (TBI) can result in long-term physical, intellectual, social, and emotional disabilities that persist long after acute treatment. Yet, even though it is a chronic condition, TBI remains an area with scarce standardization and research surrounding the complex, long-term care coordination need in this population. The purpose of this scoping review is to summarize current research on outcomes in CSHCN after implementation of care coordinators, whether individual or teams, to inform future research for youth with TBI.

Methods:

OVID/Medline, CINAHL, PsycINFO, EMBASE, and ERIC databases were searched for articles relevant to care coordination and CSHCN.

Results:

31 articles met inclusion criteria. Outcomes for children and families were grouped into 5 major categories: healthcare utilization, cost of care, disease status, parent and child quality of life, and healthcare satisfaction and perception of care.

Discussion:

Implementation of care coordinators, whether in the form of individuals, dyads, or teams, resulted in overall positive outcomes for CSHCN and their families across all 5 major outcome domains. Future research should be focused on the efficacy of care coordinators differing in profession, qualifications, and educational attainment specifically for the unique needs of children with TBI. Additionally, the application of care coordination within medical homes should be further investigated to increase proactive, preventative care of children with TBI and further reduce reactive, need-based treatment only.

Trajectory of Long-Term Outcome in Severe Pediatric Diffuse Axonal Injury: An Exploratory Study

Introduction: Pediatric severe traumatic brain injury (TBI) is one of the leading causes of disability and death. One of the classic pathoanatomic brain injury lesions following severe pediatric TBI is diffuse (multifocal) axonal injury (DAI). In this single institution study, our overarching goal was to describe the clinical characteristics and long-term outcome trajectory of severe pediatric TBI patients with DAI.

Methods: Pediatric patients (<18 years of age) with severe TBI who had DAI were retrospectively reviewed. We evaluated the effect of age, sex, Glasgow Coma Scale (GCS) score, early fever ≥ 38.5°C during the first day post-injury, the extent of ICP-directed therapy needed with the Pediatric Intensity Level of Therapy (PILOT) score, and MRI within the first week following trauma and analyzed their association with outcome using the Glasgow Outcome Score—Extended (GOS-E) scale at discharge, 6 months, 1, 5, and 10 years following injury.

Results: Fifty-six pediatric patients with severe traumatic DAI were analyzed. The majority of the patients were >5 years of age and male. There were 2 mortalities. At discharge, 56% (30/54) of the surviving patients had unfavorable outcome. Sixty five percent (35/54) of surviving children were followed up to 10 years post-injury, and 71% (25/35) of them made a favorable recovery. Early fever and extensive DAI on MRI were associated with worse long-term outcomes.

Conclusion: We describe the long-term trajectory outcome of severe pediatric TBI patients with pure DAI. While this was a single institution study with a small sample size, the majority of the children survived. Over one-third of our surviving children were lost to follow-up. Of the surviving children who had follow-up for 10 years after injury, the majority of these children made a favorable recovery.

Met and unmet rehabilitative needs among pediatric patients with moderate to severe TBI

OBJECTIVE

Estimate the probability of met and unmet post-acute rehabilitative needs among pediatric patients with moderate to severe traumatic brain injury (TBI).

PARTICIPANTS

One hundred and thirty children who received acute and post-acute rehabilitative services at a hospital for children.

METHODS

Prospective, observational study. Recommended service needs (1. Medical, 2. Psychological, 3. Cognitive/Educational, 4. Medically Based Therapies, 5. Community/Caregiver/Family Support) were collected at discharge and 1, 6, 12, and 18 months post-injury. Probabilities were estimated using nonlinear logistic regression models. The impact of age at discharge was also assessed.

RESULTS

Over time, the estimated probability of need for Medical, Medically Based Therapies, and Cognitive/Educational services were consistently high. Whereas unmet need for Medical and Medically Based Therapies were low, unmet need for Cognitive/Educational services were relatively high. Need for Psychological and Community/Caregiver/Family Support services increased in the months post-discharge, as did the probability of unmet need. Older age at discharge was associated with need for Psychological and Community/Caregiver Family Support services.

CONCLUSIONS

Findings support the long-term monitoring of need for Psychological and Community/Caregiver/Family Support services among children with moderate to severe TBI. Future research to explore the etiology of unmet needs is warranted.

Mental health after paediatric concussion: a systematic review and meta-analysis

OBJECTIVE

This systematic review and meta-analysis sought to rigorously examine mental health outcomes following paediatric concussion. To date, heterogeneous findings and methodologies have limited clinicians' and researchers' ability to meaningfully synthesise existing literature. In this context, there is a need to clarify mental health outcomes in a homogeneous sample, controlling for key methodological differences and applying a consistent definition of concussion across studies.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

We searched Medline, Embase, PsycINFO, CINAHL, SportDiscus, Scopus and PubMed.

ELIGIBILITY

Peer-reviewed studies published between 1980 and June 2020 that prospectively examined mental health outcomes after paediatric concussion, defined as per the Berlin Consensus Statement on Concussion in Sport.

RESULTS

Sixty-nine articles characterising 60 unique samples met inclusion criteria, representing 89 114 children with concussion. Forty articles (33 studies) contributed to a random effects meta-analysis of internalising (withdrawal, anxiety, depression, post-traumatic stress), externalising (conduct problems, aggression, attention, hyperactivity) and total mental health difficulties across three time points post-injury (acute, persisting and chronic). Overall, children with concussion (n=6819) experienced significantly higher levels of internalising (g=0.41-0.46), externalising (g=0.25-0.46) and overall mental health difficulties compared with controls (g=0.18-0.49; n=56 271), with effects decreasing over time.

SUMMARY/CONCLUSIONS

Our review highlights that mental health is central to concussion recovery. Assessment, prevention and intervention of mental health status should be integrated into standard follow-up procedures. Further research is needed to clarify the mechanisms underlying observed relationships between mental health, post-concussion symptoms and other psychosocial factors. Results suggest that concussion may both precipitate and exacerbate mental health difficulties, thus impacting delayed recovery and psychosocial outcomes.

Understanding the relationship between family functioning and health-related quality of life in very young children with moderate-to-severe TBI

Objective: To investigate the relationship of pre-injury and concurrent family functioning with health-related quality of life (HR QoL) following traumatic brain injury (TBI) or orthopedic injury (OI) in very young children. Method: Prospective enrollment of children ages 0-4 years who presented to the emergency department after sustaining either acute TBI or OI. This is a sub-analysis of children who completed at least one post-injury follow-up visit. At time of study enrollment, parents rated pre-injury family functioning (Family Assessment Device-General Functioning Scale) and the child's HR QoL (Pediatric Quality of Life Inventory^TM). Family functioning and HR QoL were assessed at one and six months post-injury. Mixed models were used to examine family functioning as a moderator of a child's HR QoL following injury. Results: Data were analyzed for 42 children with TBI and 24 children with OI. For both groups, better pre-injury family functioning was significantly associated with better HR QoL over time. A triple interaction of injury type by time since injury by concurrent family functioning indicated that children with TBI and poor family functioning had significantly worse HR QoL at six months post-injury relative to other groups. Conclusion: Despite a small sample size, current results underscore the importance of family functioning to recovery following early childhood TBI and support the need for continued research and development of interventions to improve outcomes in this population.

Stem Cell Therapy for Pediatric Traumatic Brain Injury

There has been a growing interest in the potential of stem cell transplantation as therapy for pediatric brain injuries. Studies in pre-clinical models of pediatric brain injury such as Traumatic Brain Injury (TBI) and neonatal hypoxia-ischemia (HI) have contributed to our understanding of the roles of endogenous stem cells in repair processes and functional recovery following brain injury, and the effects of exogenous stem cell transplantation on recovery from brain injury. Although only a handful of studies have evaluated these effects in models of pediatric TBI, many studies have evaluated stem cell transplantation therapy in models of neonatal HI which has a considerable overlap of injury pathology with pediatric TBI. In this review, we have summarized data on the effects of stem cell treatments on histopathological and functional outcomes in models of pediatric brain injury. Importantly, we have outlined evidence supporting the potential for stem cell transplantation to mitigate pathology of pediatric TBI including neuroinflammation and white matter injury, and challenges that will need to be addressed to incorporate these therapies to improve functional outcomes following pediatric TBI.

Rehabilitation models of care for children and youth living with traumatic brain and/or spinal cord injuries: A focus on family-centred care, psychosocial wellbeing, and transitions

To describe current rehabilitation models of care and programmes, in Australia and internationally, related to family-centred care, psychosocial support, and transitions used for children and youth who have sustained major traumatic brain and/or spinal cord injuries. Fourteen services were interviewed, including eight medical rehabilitation services, three community-based rehabilitation services, two insurance services, and one state-wide education service provider. Semi-structured interviews were transcribed and analysed using qualitative content analysis in NVivo. Compared to the number of services supporting children and youth with traumatic brain injury, a very limited number supported those with spinal cord injury. Although valued and often included in the model of care, family-centred care was rarely systematically evaluated by the services. Most services provided psychosocial and transition support to children and youth, and their families in the short-term post-injury, but not in the long-term. Several challenges also hindered the smooth delivery of these support services, including poor communication between service providers. These findings show that services aimed to provide the best possible care to these children and youth, and their families; guided by rehabilitation models of care. However, challenges persist with regards to delivering family-centred care, coordinating return to school, and providing long-term support for psychosocial problems and transition.

Long-Term Neurodevelopmental and Functional Outcomes of Normally Developing Children Requiring PICU Care for Bronchiolitis

Bronchiolitis is a common pediatric intensive care unit (PICU) illness and often affects generally healthy children, making it a promising disease in which to study long-term neurodevelopmental outcomes. We previously found that approximately 15% of critical bronchiolitis patients have evidence of post-PICU morbidity using coarse definitions available in administrative data sets. In this study, we measured neurodevelopmental outcomes using four more precise tools. Children who had previously been admitted to our PICU with bronchiolitis were included; those with evidence of developmental delay at PICU admission were excluded. Approximately 1 to 2 years after PICU discharge, the parent of each subject completed two questionnaires (Ages and Stages Questionnaire and Pediatric Evaluation of Disability Inventory Computer Adaptive Test). Each subject also underwent two in-person assessments administered by a certified examiner (Bayley Scales of Infant and Toddler Development, 3rd edition, and the Amiel-Tison neurological assessment). For each domain of each test, a score of > 1 standard deviation below the norm for the subject's age defined "moderate" disability and a score ≥ 2 standard deviations below the norm defined "severe" disability. Eighteen subjects (median ages of 3.7 months at PICU admission and 2.3 years at testing) were enrolled, 17 of whom were supported by high-flow nasal cannula and/or mechanical ventilation. Fifteen children (83%) scored abnormally on ≥ 1test. Eight children (44%) had disabilities in ≥ 3 domains and/or ≥ 1 severe disability identified. Our findings that motor, language, and cognitive disabilities are commonly observed months to years after critical bronchiolitis require larger studies to confirm this finding, assess causality, and identify modifiable risk factors.

Progesterone treatment following traumatic brain injury in the 11-day-old rat attenuates cognitive deficits and neuronal hyperexcitability in adolescence

Traumatic brain injury (TBI) in children younger than 4 years old results in cognitive and psychosocial deficits in adolescence and adulthood. At 4 weeks following closed head injury on postnatal day 11, male and female rats exhibited impairment in novel object recognition memory (NOR) along with an increase in open arm time in the elevated plus maze (EPM), suggestive of risk-taking behaviors. This was accompanied by an increase in intrinsic excitability and frequency of spontaneous excitatory post-synaptic currents (EPSCs), and a decrease in the frequency of spontaneous inhibitory post-synaptic currents in layer 2/3 neurons within the medial prefrontal cortex (PFC), a region that is implicated in both object recognition and risk-taking behaviors. Treatment with progesterone for the first week after brain injury improved NOR memory at the 4-week time point in both sham and brain-injured rats and additionally attenuated the injury-induced increase in the excitability of neurons and the frequency of spontaneous EPSCs. The effect of progesterone on cellular excitability changes after injury may be related to its ability to decrease the mRNA expression of the β3 subunit of the voltage-gated sodium channel and increase the expression of the neuronal excitatory amino acid transporter 3 in the medial PFC in sham- and brain-injured animals and also increase glutamic acid decarboxylase mRNA expression in sham- but not brain-injured animals. Progesterone treatment did not affect injury-induced changes in the EPM test. These results demonstrate that administration of progesterone immediately after TBI in 11-day-old rats reduces cognitive deficits in adolescence, which may be mediated by progesterone-mediated regulation of excitatory signaling mechanisms within the medial PFC.

Home-based cognitive training in pediatric patients with acquired brain injury: preliminary results on efficacy of a randomized clinical trial

Cognitive rehabilitation may compensate for cognitive deficits of children with acquired brain injury (ABI), capitalizing on the use-dependent plasticity of a developing brain. Remote computerized cognitive training (CCT) may be delivered to patients in ecological settings, ensuring rehabilitation continuity. This work evaluated cognitive and psychological adjustment outcomes of an 8-week multi-domain, home-based CCT (Lumosity Cognitive Training) in a sample of patients with ABI aged 11–16 years. Two groups of patients were engaged in five CCT sessions per week for eight weeks (40 sessions). According to a stepped-wedge research design, one group (Training-first Group) started the CCT immediately, whereas the other group (Waiting-first Group) started the CCT after a comparable time of waiting list. Changes after the training and after the waiting period were compared in the two groups. Both groups improved in visual-spatial working memory more after the training than after the waiting-list period. The Training-first group improved also in arithmetic calculation speed. Findings indicate that a multi-domain CCT can produce benefits in visual-spatial working memory, probably because, in accordance with previous research, computer games heavily tax visuo-spatial abilities. This suggests that the prolonged stimulation of the same cognitive ability may generate the greatest benefits in children with ABI.

Epidemiology of Pediatric Traumatic Brain Injury and Hypothalamic-Pituitary Disorders in Arizona

Traumatic brain injury (TBI) in children can result in long-lasting social, cognitive, and neurological impairments. In adults, TBI can lead to endocrinopathies (endocrine system disorders), but this is infrequently reported in children. Untreated endocrinopathies can elevate risks of subsequent health issues, such that early detection in pediatric TBI survivors can initiate clinical interventions. To understand the risk of endocrinopathies following pediatric TBI, we identified patients who had experienced a TBI and subsequently developed a new-onset hypothalamic regulated endocrinopathy (n = 498). We hypothesized that pediatric patients who were diagnosed with a TBI were at higher risk of being diagnosed with a central endocrinopathy than those without a prior diagnosis of TBI. In our epidemiological assessment, we identified pediatric patients enrolled in the Arizona Health Care Cost Containment System (AHCCCS) from 2008 to 2014 who were diagnosed with one of 330 TBI International Classification of Diseases (ICD)-9 codes and subsequently diagnosed with one of 14 central endocrinopathy ICD-9 codes. Additionally, the ICD-9 code data from over 600,000 Arizona pediatric patients afforded an estimate of the incidence, prevalence, relative risk, odds ratio, and number needed to harm, regarding the development of a central endocrinopathy after sustaining a TBI in Arizona Medicaid pediatric patients. Children with a TBI diagnosis had 3.22 times the risk of a subsequent central endocrine diagnosis compared with the general population (±0.28). Pediatric AHCCCS patients with a central endocrine diagnosis had 3.2-fold higher odds of a history of a TBI diagnosis than those without an endocrine diagnosis (±0.29). Furthermore, the number of patients with a TBI diagnosis for one patient to receive a diagnosis of a central endocrine diagnosis was 151.2 (±6.12). Female subjects were more likely to present with a central endocrine diagnosis after a TBI diagnosis compared to male subjects (64.1 vs. 35.9%). These results are the first state-wide epidemiological study conducted to determine the risk of developing a hypothalamic-pituitary disorder after a TBI in the pediatric population. Our results contribute to a body of knowledge demonstrating a TBI etiology for idiopathic endocrine disorders, and thus advise physicians with regard to TBI follow-up care that includes preventive screening for endocrine disorders.

Short term outcomes of children with abusive head trauma two years post injury: A retrospective study

PURPOSE

Abusive head trauma (AHT) can have debilitating sequelae for children who survive. A retrospective medical record review was used to describe short-term developmental outcomes of children with AHT and identify predictors of poorer outcomes.

METHOD

Children with AHT who received follow up by the hospital's rehabilitation department for 12 to 24 months post-injury were included in this review. Data for 85 children were collected on hearing, vision, gross motor, fine motor, speech and language, cognition, play, adaptive functioning, behaviour and personal-social skills.

RESULTS

Global assessment found 42% of children had a good recovery, 34% had a moderate disability and 24% had a severe disability. For whom there was data, more than half had abnormal cognition, behaviour and personal-social skills, whilst more than a third had abnormal speech and language, neurological signs on last assessment, vision, play skills, and gross and fine motor skills. Factors that predicted poorer prognosis across all developmental domains included paediatric intensive care unit admission, longer length of hospital stay, breathing difficulty and lower Glasgow Coma Scale on presentation.

CONCLUSION

This study highlights the substantial number of children who have abnormal development in the short-term post-AHT and assists in identifying those who require extensive long-term follow up.

Virtual Reality for Pediatric Traumatic Brain Injury Rehabilitation: A Systematic Review

Objective. Pediatric traumatic brain injury (TBI) is associated with physical and psychobehavioral impairment in children. Effective rehabilitation programs postinjury are critical for children with TBI. Virtual reality (VR) has been increasingly adopted for brain injury rehabilitation. However, scientific synthesis is lacking in evaluating its effectiveness in pediatric TBI rehabilitation. This article aimed to conduct a systematic review on the effectiveness of VR-based pediatric TBI rehabilitation. Methods. A systematic literature search was conducted in PubMed, PsycInfo, SCOPUS, CENTRAL, BioMed Central, CiNAHL, and Web of Science through November 2015. Personal libraries and relevant references supplemented the search. Two authors independently reviewed the abstracts and/or full text of 5824 articles. Data extraction and qualitative synthesis was conducted along with quantitative assessment of research quality by 2 authors. Results. A positive impact was found for VR-based interventions on children's physical rehabilitation post-TBI. The quality of research evidence was moderate, which largely suffered from small samples, lack of immersive VR experience, and lack of focus on socioemotional outcomes post-TBI. Conclusions. The present review identified positive effects of VR interventions for pediatric TBI rehabilitation especially in physical outcomes. Future research should include larger samples and broader post-TBI outcomes in children using VR-based interventions.

Longitudinal Neuroimaging in Pediatric Traumatic Brain Injury: Current State and Consideration of Factors That Influence Recovery

Traumatic brain injury (TBI) is a leading cause of death and disability for children and adolescents in the U.S. and other developed and developing countries. Injury to the immature brain varies greatly from that of the mature, adult brain due to numerous developmental, pre-injury, and injury-related factors that work together to influence the trajectory of recovery during the course of typical brain development. Substantial damage to brain structure often underlies subsequent functional limitations that persist for years following pediatric TBI. Advances in neuroimaging have established an important role in the acute management of pediatric TBI, and magnetic resonance imaging (MRI) techniques have a particular relevance for the sequential assessment of long-term consequences from injuries sustained to the developing brain. The present paper will discuss the various factors that influence recovery and review the findings from the present neuroimaging literature to assess altered development and long-term outcome following pediatric TBI. Four MR-based neuroimaging modalities have been used to examine recovery from pediatric TBI longitudinally: (1) T1-weighted structural MRI is sensitive to morphological changes in gray matter volume and cortical thickness, (2) diffusion-weighted MRI is sensitive to changes in the microstructural integrity of white matter, (3) MR spectroscopy provides a sensitive assessment of metabolic and neurochemical alterations in the brain, and (4) functional MRI provides insight into the functional changes that occur as a result of structural damage and typical developmental processes. As reviewed in this paper, 13 cohorts have contributed to only 20 studies published to date using neuroimaging to examine longitudinal changes after TBI in pediatric patients. The results of these studies demonstrate considerable heterogeneity in post-injury outcome; however, the existing literature consistently shows that alterations in brain structure, function, and metabolism can persist for an extended period of time post-injury. With larger sample sizes and multi-site cooperation, future studies will be able to further examine potential moderators of outcome, such as the developmental, pre-injury, and injury-related factors discussed in the present review.

Juvenile mild traumatic brain injury elicits distinct spatiotemporal astrocyte responses

Mild-traumatic brain injury (mTBI) represents ~80% of all emergency room visits and increases the probability of developing long-term cognitive disorders in children. To date, molecular and cellular mechanisms underlying post-mTBI cognitive dysfunction are unknown. Astrogliosis has been shown to significantly alter astrocytes' properties following brain injury, potentially leading to significant brain dysfunction. However, such alterations have never been investigated in the context of juvenile mTBI (jmTBI). A closed-head injury model was used to study jmTBI on postnatal-day 17 mice. Astrogliosis was evaluated using glial fibrillary acidic protein (GFAP), vimentin, and nestin immunolabeling in somatosensory cortex (SSC), dentate gyrus (DG), amygdala (AMY), and infralimbic area (ILA) of prefrontal cortex in both hemispheres from 1 to 30 days postinjury (dpi). In vivo T2-weighted-imaging (T2WI) and diffusion tensor imaging (DTI) were performed at 7 and 30 dpi to examine tissue level structural alterations. Increased GFAP-labeling was observed up to 30 dpi in the ipsilateral SSC, the initial site of the impact. However, vimentin and nestin expression was not perturbed by jmTBI. The morphology of GFAP positive cells was significantly altered in the SSC, DG, AMY, and ILA up to 7 dpi that some correlated with magnetic resonance imaging changes. T2WI and DTI values were significantly altered at 30 dpi within these brain regions most prominently in regions distant from the impact site. Our data show that jmTBI triggers changes in astrocytic phenotype with a distinct spatiotemporal pattern. We speculate that the presence and time course of astrogliosis may contribute to pathophysiological processes and long-term structural alterations following jmTBI.

Effect of Robot-Assisted Gait Training in a Large Population of Children With Motor Impairment Due to Cerebral Palsy or Acquired Brain Injury

OBJECTIVE

To evaluate retrospectively the effect of robotic rehabilitation in a large group of children with motor impairment; an additional goal was to identify the effects in children with cerebral palsy (CP) and acquired brain injury (ABI) and with different levels of motor impairment according to the Gross Motor Function Classification System. Finally, we examined the effect of time elapsed from injury on children's functions.

DESIGN

A cohort, pretest-posttest retrospective study was conducted.

SETTING

Hospitalized care.

PARTICIPANTS

A total of 182 children, 110 with ABI and 72 with CP and with Gross Motor Function Classification System (GMFCS) levels I-IV, were evaluated retrospectively.

INTERVENTIONS

Patients underwent a combined treatment of robot-assisted gait training and physical therapy.

MAIN OUTCOME MEASURES

All the patients were evaluated before and after the training using the 6-minute walk test and the Gross Motor Function Measure. A linear mixed model with 3 fixed factors and 1 random factor was used to evaluate improvements.

RESULTS

The 6-minute walk test showed improvement in the whole group and in both ABI and CP. The Gross Motor Function Measure showed improvement in the whole group and in the patients with ABI but not in children with CP. The GMFCS analysis showed that all outcomes improved significantly in all classes within the ABI subgroup, whereas improvements were significant only for GMFCS III in children with CP.

CONCLUSIONS

Children with motor impairment can benefit from a combination of robotic rehabilitation and physical therapy. Our data suggest positive results for the whole group and substantial differences between ABI and CP subgroups, with better results for children with ABI, that seem to be consistently related to time elapsed from injury.

Remote Technology-Based Training Programs for Children with Acquired Brain Injury: A Systematic Review and a Meta-Analytic Exploration

Introduction

Multidisciplinary rehabilitation interventions are considered to be a need for children with acquired brain injury (ABI), in order to remediate the important sequelae and promote adjustment. Technology-based treatments represent a promising field inside the rehabilitation area, as they allow delivering interventions in ecological settings and creating amusing exercises that may favor engagement. In this work, we present an overview of remote technology-based training programs (TP) addressing cognitive and behavioral issues delivered to children with ABI and complement it with the results of a meta-analytic exploration.

Evidence Acquisition

We performed the review process between January and February 2019. 32 studies were included in the review, of which 14 were further selected to be included in the meta-analysis on TP efficacy.

Evidence Synthesis

Based on the review process, the majority of TP addressing cognitive issues and all TP focusing on behavioral issues were found to be effective. Two meta-analytic models examining the means of either cognitive TP outcomes or behavioral TP outcomes as input outcome yielded a nonsignificant effect size for cognitive TP and a low-moderate effect size for behavioral TP. Additional models on outcomes reflecting the greatest beneficial effects of TP yielded significant moderate effect sizes for both types of TP. Nevertheless, consistent methodological heterogeneity was observed, pointing to cautious interpretation of findings. A subgroup analysis on visuospatial skill outcomes showed a smaller yet significant effect size of cognitive TP, with low heterogeneity, providing a more reliable estimation of overall cognitive TP effects.

Conclusions

Promising results on remote cognitive and behavioral TP efficacy emerged both at the review process and at the meta-analytic investigation. Nevertheless, the high heterogeneity that emerged across studies prevents us from drawing definite conclusions. Further research is needed to identify whether specific training characteristics and population subgroups are more likely to be associated with greater training efficacy.

Participation seven years after severe childhood traumatic brain injury. Disabil Rehabil 2019;42:2402-2411. [PMID: 30950661 DOI: 10.1080/09638288.2019.1594398]

Purpose: Participation in home, school and community activities is considered as the ultimate aim of rehabilitation. The aims of this study were to examine participation seven years post-severe childhood traumatic brain injury and factors associated with participation.Materials and methods: Participants were enrolled in the Traumatisme Grave de l'Enfant (Severe Childhood Injury) cohort study following severe accidental childhood traumatic brain injury. Participation seven years post-injury, was examined using parent- and self-report forms of the Child and Adolescent Scale of Participation among 37 patients [62% males, mean age 15.4 years (SD = 4.4), mean length of coma 6.68 days (SD = 4.96)] and 33 matched controls.Results: Parent reports indicated significantly lower participation among patients compared to controls, but the self-reports did not. In the traumatic brain injury group, parent-reported participation was variable, with 22% of the patients clearly showing greater restrictions than controls. Participation restrictions were significantly associated with injury severity, poor functional outcome one-year post-injury, executive and behavioral difficulties and higher fatigue levels seven years post-injury, but not with pre-injury nor family factors.Conclusions: Several years after severe childhood traumatic brain injury, participation appears to depend more on injury-related factors than on environmental factors. In self-reports assessments of participation, it could be difficult for children and adolescents to distinguish capacity from performance.Implications for rehabilitationParticipation outcomes were highly variable in a sample of patients who sustained severe childhood traumatic brain injury.Participation should be assessed systematically following severe traumatic brain injury, both initially but also in the long-term, ideally using a combination of self- and proxy-report measures.Among patients with severe injuries, the influence of initial brain injury severity markers on participation seems much stronger than that of social/family environment factors.Children's and adolescents' self-reported participation assessed with the Child and Adolescent Scale of Participation may be difficult to interpret.

"To whom did I tell that information?": Relationship between destination memory and theory of mind in traumatic brain injury

Traumatic Brain Injury (TBI) has been widely associated with impairment of social cognition. We therefore investigated the relationship between the ability to infer and predict other's mental states (i.e., Theory of Mind, ToM) and the ability to remember to whom one has sent information (i.e., destination memory). We invited patients with TBI and control subjects, on a destination memory task, to tell proverbs to pictures of celebrities, so as to remember to which celebrity they had previously told the proverbs. Participants also performed affective (i.e., Reading the Mind in the Eyes) and cognitive (i.e., the false belief) tests of ToM. Results demonstrated lower destination memory, affective, and cognitive ToM performance in TBI patients than in control subjects. Critically, analysis demonstrated significant positive correlations between destination memory and first order and second cognitive order ToM in patients with TBI, but no significant correlations between destination memory and affective ToM in these patients. Our results demonstrate a relationship between difficulties of TBI patients to infer and predict cognitive states of interlocutors and difficulties to remember to which interlocutor information has been told.
