Abstract
Endoplasmic reticulum (ER) stress and neuroinflammation play an important role in secondary brain damage after traumatic brain injury (TBI). Due to the complex brain cytoarchitecture, multiple cell types are affected by TBI. However, cell type-specific and sex-specific responses to ER stress and neuroinflammation remain unclear. Here we investigated differential regulation of ER stress and neuroinflammatory pathways in neurons and microglia during the acute phase post-injury in a mouse model of impact acceleration TBI in both males and females. We found that TBI resulted in significant weight loss only in males, and sensorimotor impairment and depressive-like behaviors in both males and females at the acute phase post-injury. By concurrently isolating neurons and microglia from the same brain sample of the same animal, we were able to evaluate the simultaneous responses in neurons and microglia towards ER stress and neuroinflammation in both males and females. We discovered that the ER stress and anti-inflammatory responses were significantly stronger in microglia, especially in female microglia, compared with the male and female neurons. Whereas the degree of phosphorylated-tau (pTau) accumulation was significantly higher in neurons, compared with the microglia. In conclusion, TBI resulted in behavioral deficits and cell type-specific and sex-specific responses to ER stress and neuroinflammation, and abnormal protein accumulation at the acute phase after TBI in immature mice.

Abstract
This study investigated parental reports of the level of care and needs 7-years following severe childhood traumatic brain injury (TBI), and the factors associated with this outcome. From the 65 children (0-15 years) consecutively admitted to the Parisian regional TBI reference intensive care unit following severe TBI, included in this prospective longitudinal study, 39 patients [M(SD) age at injury = 7.5 years (4.6) and assessment 15.3(4.4)] were followed 7-years post-injury and matched with a control group composed of typically developing participants (n = 34) matched by age, sex and parental education level. We used the Care and Need Scale (CANS) and its Pediatric version (PCANS) to assess the primary outcome 7-years post-injury. Concurrent measures included overall level of disability, and parent- and/or self-reported questionnaires assessing executive functioning, behavior, quality of life, fatigue, participation and caregivers' burden. The level of care and needs was significantly higher in the TBI group than in the control group, the difference being significant with the CANS only. PCANS scores were extremely variable in the control group. High level of dependency was associated with initial TBI severity (higher coma duration and initial Injury Severity Score), higher levels of behavioral problems, executive function deficits, fatigue, and lower participation levels. Caregivers' burden was strongly associated with the CANS. The CANS provides a simple and reliable measure of the support needed long-term after childhood TBI, in accordance with previous studies. The PCANS scores were not significantly different between the TBI and the control groups, which seems to illustrate the difficulty to assess accurately mild-to-moderate deficits of functional independence/adaptive behavior in children based exclusively on parental reports.

Abstract
OBJECTIVE To identify latent trajectories of IQ over time after pediatric traumatic brain injury (TBI) and examine the predictive value of risk factors within and across recovery trajectories. METHOD 206 children ages 3-7 years at injury were included: 87 TBI (23 severe, 21 moderate, 43 complicated mild) and 119 orthopedic injury (OI). We administered intelligence tests shortly after injury (1½ months), 12 months, and 6.8 years postinjury. Latent class growth modeling was used to identify latent subgroups. Separate models examined verbal and nonverbal IQ recovery trajectories following TBI versus OI. Variables included: age at injury, sex, race, socioeconomic status, injury severity, quality of the home environment, family functioning, and parenting style. RESULTS Both the TBI and OI analyses yielded different growth models for nonverbal (k = 3) and verbal IQ (k = 3). Although all models resulted in 3 latent classes (below average, average, and aboveaverage performance); trajectory shapes, contributors to class membership, and performance within each class varied by injury group and IQ domain. TBI severity was associated with class membership for nonverbal IQ, with less severe injuries associated with higher IQ scores; however, TBI severity did not influence verbal IQ class membership. Parenting style had a more prominent effect on verbal and nonverbal IQ within the TBI than OI trajectories. CONCLUSIONS Findings suggest TBI severity is related to recovery trajectories for nonverbal but not verbal IQ and parenting style has stronger effects on recovery in TBI than OI. Results highlight the importance of parental factors on long-term recovery after TBI.

Abstract
BACKGROUND Traumatic brain injury (TBI) is a major cause of morbidity and mortality globally. TBI is often associated with other physical or psychological issues resulting in high hospitalization costs. TBI incidence and recovery can vary with the external cause being intentional or unintentional. It is important to monitor the rates of TBI hospitalizations related to different external causes. This study examined the annual rate, comorbidity and length of stay associated with assault-related TBI hospitalizations and compare it with other external causes, by age and sex in Canada from 2010 to 2021. METHODS Discharge Abstract Database was used to extract cases of TBI (2010-2021). ICD-10-CA codes were used to classify all cases with TBI as per assault and other external causes (falls; transport; sport, physical activity and recreation; struck by). Additional variables, including age, sex, comorbidity and length of stay, were examined. Time trends were quantified using Joinpoint regression. RESULTS The average annual percent increase for all TBI hospitalizations from 2010 to 2021 was not significant at 0.1%. Females accounted for 35.8% of these TBI hospitalizations. From 2010 to 2021, assault-related TBI hospitalizations showed a significant annual decline of 4.1% for males and a significant increase of 1.2% for females. Increase in TBI hospitalizations related to falls showed an average annual percent increase of 1.4% for males and 2.2% for females. A significant decrease was observed for TBI hospitalizations related to the other three (transport, SPAR and struck by) external causes for both sexes from 2010 to 2021. Infants and children under 10 years of age had higher percentages of cases with comorbidities and higher length of stay for assault-related TBI hospitalizations. CONCLUSIONS Assault-related TBI hospitalization rates decreased overall and among males, rates among females increased from 2010 to 2021. These results underscore the importance of targeted prevention efforts for TBI related to different external causes, age and sex, and continued surveillance to monitor the epidemiology of assault-related TBI.

Abstract
Traumatic brain injury (TBI) in children often leads to poor developmental outcomes attributable to progressive cell loss caused by secondary injuries, including endoplasmic reticulum (ER) stress. Buprenorphine (BPN) is commonly used in children for pain management; however, the effects of BPN on ER stress in the pediatric population are still inconclusive. This study investigated the sex-specific effects of BPN on ER stress, abnormal protein accumulation, and cell loss in a mouse impact acceleration model of pediatric TBI. On post-natal day 20-21 (P20-21), male and female littermates were randomized into sham, TBI + saline and TBI + BPN groups. BPN (0.075 mg/kg) was administered to TBI + BPN mice at 30 min after injury and then every 6-12 h for 2 days. The impact of BPN was evaluated at 1, 3, and 7 days post-injury. We found that TBI induced more prominent ER stress pathway activation at 1 and 3 days post-injury in males, compared to females, whereas abnormal protein accumulation and cell loss were more severe in females at 7 days post-injury, compared with males. Although BPN partially ameliorated abnormal protein accumulation and cell loss in both males and females, BPN only decreased ER stress pathway activation in males, not in females. In conclusion, BPN exhibits sex-specific effects on ER stress, abnormal protein accumulation, and cell loss in a time-dependent manner at the acute phase after pediatric TBI, which provides the rationale to assess the potential effects of BPN on long-term outcomes after pediatric TBI in both males and females.

Abstract
OBJECTIVE To determine whether exposure to traumatic brain injury (TBI) before 10 years of age is associated with development of a mood or anxiety disorder by 25 years of age, and whether sex or injury severity influences this risk. SETTING Olmsted County, Minnesota. PARTICIPANTS A total of 5518 persons born from January 1, 1976, through December 31, 1982. DESIGN Population-based, birth cohort study. Children sustaining TBI before 10 years of age (index date) were confirmed by manual record review and classified by injury severity using the Mayo Classification System. Each TBI case was age- and sex-matched to 2 referents from the same birth cohort without a history of TBI at the index date. Cox proportional hazards models were fit to compare the risk of a subsequent clinically diagnosed mood or anxiety disorder by 25 years of age between TBI cases and referents. Separate analysis was performed stratified by sex and injury severity. MAIN MEASURES Incidence of mood and anxiety disorders determined through clinical diagnostic codes and manual record review. RESULTS The study included 562 children (238 females [42.3%] and 324 males [57.7%]) with TBI before 10 years of age (mean [SD] age at TBI: 4.7 [2.8] years). At least 1 mood or anxiety disorder was diagnosed for 115 persons with TBI and 215 referents. No statistically significant association existed between childhood TBI status and anxiety disorder (adjusted hazard ratio [aHR], 1.01 [95% confidence interval (CI), 0.71-1.43]; P = .97) or mood disorder (aHR, 1.16 [95% CI, 0.92-1.47]; P = .21). However, females who sustained TBI had a significantly increased risk of a subsequently diagnosed mood disorder compared with age-matched female referents (aHR, 1.40 [95% CI, 1.04-1.89]; P = .03). CONCLUSIONS This study suggests that isolated TBI before 10 years of age is not significantly associated with an increased risk of anxiety or mood disorder by 25 years of age, though females may be at an increased risk.

Abstract
OBJECTIVE To assess the feasibility and acceptability of an online parenting-skills program for caregivers of young children with traumatic brain injury (TBI). Positive parenting contributes to recovery following early TBI and social and emotional development in typically developing children. Yet, few interventions have been designed to support psychosocial recovery and subsequent development after early TBI. METHODS This study protocol was registered with clinicaltrials.gov (NCT05160194). We utilized an academic hospital's Trauma Registry to recruit caregivers of children, ages 0-4 years, previously hospitalized for TBI. The GROW intervention integrated six online learning modules with videoconference meetings with a coach to review and practice skills while receiving in vivo coaching and feedback. Interactive modules addressed strategies for responsive parenting, stimulating cognition, and managing parenting stress. Enrollment and retention rates served as feasibility metrics and satisfaction surveys assessed acceptability. RESULTS 18 of 72 families contacted (25%) consented, and 11 of 18 (61%) completed the intervention and follow-up assessments. All participants rated the intervention as helpful and indicated that they would recommend the intervention to others. All endorsed a better understanding of brain injury and how to optimize their child's recovery and development. Both coaches rated intervention delivery as comparable to traditional face-to-face treatment. CONCLUSIONS Low levels of uptake and initial engagement underscore the challenges of intervening with caregivers following early TBI, which likely were exacerbated due to the COVID-19 pandemic. High levels of acceptability and perceived benefit support the potential utility of GROW while highlighting the need to improve accessibility and early engagement.

Abstract
IMPORTANCE Among children, infants and toddlers have some of the highest rates of traumatic brain injury (TBI), but longitudinal information on their developmental outcomes to guide postinjury surveillance is sparse. OBJECTIVE To evaluate infants' and toddlers' development over 3 years following TBI compared with those with orthopedic injury (OI). DESIGN, SETTING, AND PARTICIPANTS A longitudinal observational cohort study was conducted at 2 level 1 pediatric trauma centers from January 20, 2013, to September 30, 2015; data analysis was performed from May 12 to October 20, 2021. Participants included children injured when younger than 31 months with TBI or OI who received emergency department care. EXPOSURES Mild, moderate, or severe TBI or OI. MAIN OUTCOMES AND MEASURES Parents completed baseline measures representing preinjury status and 3-, 12-, 24-, and 36-month postinjury status, using the Ages & Stages Questionnaire-3 (ASQ-3), with a mean reference value of 50 and higher scores indicating more advanced development. Linear mixed models characterized children's outcomes for each ASQ-3 domain after adjustment for baseline ASQ-3, injury severity and group, age, injury mechanism (abuse or not), sex, prematurity, family function, social capital, and time. Interactions with time were evaluated. RESULTS Consent for participation was provided for 195 children; 184 parents (94%) completed a baseline survey. The cohort included 168 children who completed at least 1 follow-up survey: 48 (29%) mild; 54 (32%) complicated mild/moderate; 21 (13%) severe TBI; and 45 (27%) orthopedic injury. The cohort included 95 boys (57%), 49% injured before age 1 year; and 13% injured by abuse. Mean (SD) age at the time of injury was 13.9 (9.4) months. At 36 months, children with mild or complicated mild/moderate TBI performed similarly to children with OI across ASQ-3 domains. Children with severe TBI performed poorly as shown by negative mean differences in communication (-8.8; 95% CI, -13.8 to -3.8); gross motor (-10.1; 95% CI, -15.1 to -5.1); problem solving (-6.6; 95% CI, -11.2 to -1.9), and personal social (-6.3; 95% CI, -10.4 to -2.1) domains with little recovery over time. Children with abusive injury experienced decrements in ability over time in fine motor and personal social skills. Social capital was protective in communication (mean, 1.5; 95% CI, 0.3-2.7) and problem solving (mean, 1.2; 95% CI, 0.1-2.3) domains. CONCLUSIONS AND RELEVANCE In this cohort study of children with TBI, children with severe injury showed little recovery. These findings suggest that early childhood intervention is needed, while children with milder injury remained on their developmental track and should continue routine developmental surveillance.

Abstract
Major advances in pediatric intensive care (PICU) have led to increased child survival. However, the long-term outcomes among these children following PICU discharge are a concern. Most children admitted to PICU are under five years of age, and the stressors of critical illness and necessary interventions can affect their ability to meet crucial developmental milestones. Understanding the neuroscience of brain development and vulnerability can inform PICU clinicians of new ways to enhance and support the care of these most vulnerable children and families. This review paper first explores the evidence-based neuroscience principles of brain development and vulnerability and the impact of illness and care on children's brains and ultimately wellbeing. Implications for clinical practice and training are further discussed to help optimize brain health in children who are experiencing and surviving a critical illness or injury.

Abstract
Up to 30% of youth with concussion experience PPCSs (PPCS) lasting 4 weeks or longer, and can significantly impact quality of life. Magnetic resonance imaging (MRI) has the potential to increase understanding of causal mechanisms underlying PPCS. However, there are no clear modalities to assist in detecting PPCS. This scoping review aims to synthesize findings on utilization of MRI among children and youth with PPCS, and summarize progress and limitations. Thirty-six studies were included from 4907 identified papers. Many studies used multiple modalities, including (1) structural (n = 27) such as T1-weighted imaging, diffusion weighted imaging, and susceptibility weighted imaging; and (2) functional (n = 23) such as functional MRI and perfusion-weighted imaging. Findings were heterogeneous among modalities and regions of interest, which warrants future reviews that report on the patterns and potential advancements in the field. Consideration of modalities that target PPCS prediction and sensitive modalities that can supplement a biopsychosocial approach to PPCS would benefit future research.

Abstract
Cortical gyrification, as a specific measure derived from magnetic resonance imaging, remains understudied in mild traumatic brain injury (mTBI). Local gyrification index (lGI) and mean curvature are related measures indexing the patterned folding of the cortex,ml which reflect distinct properties of cortical morphology and geometry. Using both metrics, we examined cortical gyrification morphology in 59 adult males with mTBI (n = 29) versus those without (n = 30) mTBI in the subacute phase of injury (between 2 weeks and 3 months). The effect of IQ on lGI and brain-symptom relations were also examined. General linear models revealed greater lGI in mTBI versus controls in the frontal lobes bilaterally, but reduced lGI in mTBI of the left temporal lobe. An age-related decrease in lGI was found in numerous areas, with no significant group-by-age interaction effects observed. Including other factors (i.e., mTBI severity, symptoms, and IQ) in the lGI model yielded similar results with few exceptions. Mean curvature analyses depicted a significant group-by-age interaction with the absence of significant main effects of group or age. Our results suggest that cortical gyrification morphology is adversely affected by mTBI in both frontal and temporal lobes, which are thought of as highly susceptible regions to mTBI. These findings contribute to understanding the effects of mTBI on neuromorphological properties, such as alterations in cortical gyrification, which reflect underlying microstructural changes (i.e., apoptosis, neuronal number, or white matter alterations). Future studies are needed to infer causal relationships between micro- and macrostructural changes after an mTBI and investigate potential sex differences.

Abstract
INTRODUCTION In Australia, while paediatric intensive care unit (PICU) mortality has dropped to 2.2%, one in three survivors experience long-term neurodevelopmental impairment, limiting their life-course opportunities. Unlike other high-risk paediatric populations, standardised routine neurodevelopmental follow-up of PICU survivors is rare, and there is limited knowledge regarding the best methods. The present study intends to pilot a combined multidisciplinary, online screening platform and general practitioner (GP) shared care neurodevelopmental follow-up model to determine feasibility of a larger, future study. We will also assess the difference between neurodevelopmental vulnerability and parental stress in two intervention groups and the impact of child, parent, sociodemographic and illness/treatment risk factors on child and parent outcomes. METHODS AND ANALYSIS Single-centre randomised effectiveness-implementation (hybrid-2 design) pilot trial for parents of children aged ≥2 months and <4 years discharged from PICU after critical illness or injury. One intervention group will receive 6 months of collaborative shared care follow-up with GPs (supported by online outcome monitoring), and the other will be offered self-directed screening and education about post-intensive care syndrome and child development. Participants will be followed up at 1, 3 and 6 months post-PICU discharge. The primary outcome is feasibility. Secondary outcomes include neurodevelopmental vulnerability and parental stress. An implementation evaluation will analyse barriers to and facilitators of the intervention. ETHICS AND DISSEMINATION The study is expected to lead to a full trial, which will provide much-needed guidance about the clinical effectiveness and implementation of follow-up models of care for children after critical illness or injury. The Children's Health Queensland Human Research Ethics Committee approved this study. Dissemination of the outcomes of the study is expected via publication in a peer-reviewed journal, presentation at relevant conferences, and via social media, podcast presentations and open-access medical education resources. REGISTRATION DETAILS The trial was prospectively registered with the Australian New Zealand Clinical Trials Registry as 'Pilot testing of a collaborative Shared Care Model for Detecting Neurodevelopmental Impairments after Critical Illness in Young Children' (the DAISY Pilot Study). TRIAL REGISTRATION NUMBER ACTRN12621000799853.

Abstract
Over half of fatal pediatric traumatic brain injuries are estimated to be the result of physical abuse, i.e., abusive head trauma (AHT). Although intimate partner violence (IPV) is a well-established risk for child maltreatment, little is known about IPV as an associated risk factor specifically for AHT. We performed a single-institution, retrospective review of all patients (0-17 years) diagnosed at a Level 1 pediatric trauma center with head trauma who had been referred to an in-hospital child protection team for suspicion of AHT between 2010 and 2016. Data on patient demographics, hospitalization, injury, family characteristics, sociobehavioral characteristics, physical examination, laboratory findings, imaging, discharge, and forensic determination of AHT were extracted from the institution's forensic registry. Descriptive statistics (mean, median), chi-square and Mann-Whitney U tests were used to compare patients with fatal head injuries to patients with nonfatal head injuries by clinical characteristics, family characteristics, and forensic determination. Multiple logistic regression was used to estimate adjusted odds ratios for the presence of IPV as an associated risk of AHT while controlling for other clinical and family factors. Of 804 patients with suspicion for AHT in the forensic registry, there were 240 patients with a forensic determination of AHT; 42 injuries were fatal. There were 101 families with a reported history of IPV; 64.4% of patients in families with reported IPV were <12 months of age. IPV was associated with a twofold increase in the risk of AHT (Exp(β) = 2.3 [p = .02]). This study confirmed IPV was an associated risk factor for AHT in a single institution cohort of pediatric patients with both fatal and nonfatal injuries. Identifying IPV along with other family factors may improve detection and surveillance of AHT in medical settings and help reduce injury, disability, and death.

Traumatic Brain Injury Characteristics Predictive of Subsequent Sleep-Wake Disturbances in Pediatric Patients. BIOLOGY 2022; 11:biology11040600. [PMID: 35453799 PMCID: PMC9030185 DOI: 10.3390/biology11040600] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/09/2022] [Revised: 04/11/2022] [Accepted: 04/13/2022] [Indexed: 12/02/2022]
Abstract
Simple Summary Traumatic brain injury is a leading cause of death and disabilities in children and adolescents. Poor sleep after brain injury can slow recovery and worsen outcomes. We investigated clinical sleep problems following pediatric brain injury. We examined characteristics of the injury and details about the patients that may be risk factors for developing sleep problems. The number of patients that developed problems with their sleep after a brain injury was similar between genders. The probability of insomnia increased with increasing patient age. The probability of ‘difficulty sleeping’ was highest in 7–9 year-old brain-injured patients. Older patients had a shorter time between brain injury and sleep problems compared to younger patients. Patients with severe brain injury had the shortest time between brain injury and development of sleep problems, whereas patients with mild or moderate brain injury had comparable times between brain injury and the onset of poor sleep. Multiple characteristics of brain injury and patient details were identified as risk factors for developing sleep problems following a brain injury in children. Untreated sleep problems after a brain injury can worsen symptoms, lengthen hospital stays, and delay return to school. Identifying risk factors could improve the diagnosis, management, and treatment of sleep problems in survivors of pediatric brain injury. Abstract The objective of this study was to determine the prevalence of sleep-wake disturbances (SWD) following pediatric traumatic brain injury (TBI), and to examine characteristics of TBI and patient demographics that might be predictive of subsequent SWD development. This single-institution retrospective study included patients diagnosed with a TBI during 2008–2019 who also had a subsequent diagnosis of an SWD. Data were collected using ICD-9/10 codes for 207 patients and included the following: age at initial TBI, gender, TBI severity, number of TBIs diagnosed prior to SWD diagnosis, type of SWD, and time from initial TBI to SWD diagnosis. Multinomial logit and negative-binomial models were fit to investigate whether the multiple types of SWD and the time to onset of SWD following TBI could be predicted by patient variables. Distributions of SWD diagnosed after TBI were similar between genders. The probability of insomnia increased with increasing patient age. The probability of ‘difficulty sleeping’ was highest in 7–9 year-old TBI patients. Older TBI patients had shorter time to SWD onset than younger patients. Patients with severe TBI had the shortest time to SWD onset, whereas patients with mild or moderate TBI had comparable times to SWD onset. Multiple TBI characteristics and patient demographics were predictive of a subsequent SWD diagnosis in the pediatric population. This is an important step toward increasing education among providers, parents, and patients about the risk of developing SWD following TBI.

Abstract
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.

Abstract
PRIMARY OBJECTIVE Complicated mild traumatic brain injury (C-mTBI) refers to CT positive patients with clinically mild TBI. This study investigates the association between CT head findings at time of injury and recovery of paediatric patients with C-mTBI. RESEARCH DESIGN Retrospective survey and chart review. METHODS For paediatric patients with C-mTBI (N = 77), CT findings associated with corresponding degree and lengths of recovery from C-mTBI using logistic regression analysis. RESULTS There was a trend that the odds of incomplete recovery at the time of survey was higher for older children than for younger children (OR = 1.14, 95% CI = 0.98-1.32, p = 0.072). There was a trend that the odds of incomplete recovery (OR = 6.26, 95% CI = 0.97-40.57, p = 0.054) and longer duration for recovery (OR = 8.14, 95% CI = 0.78-84.46, p = 0.079) was higher for children with multiple haemorrhagic contusions than those with single haemorrhagic contusion. No other imaging patterns predicted degree or length of recovery with statistical significance (p > 0.05). CONCLUSIONS Other than the presence of multiple haemorrhagic contusions, no other pattern of imaging abnormality in paediatric C-mTBI appears to be associated with degree or length of recovery. Further studies with larger cohorts are encouraged.

Abstract
There is increasing empirical focus on the effects of early traumatic brain injuries (TBI; i.e., before the age of six years) on child development, but this literature has never been synthetized comprehensively. This systematic review aimed to document the cognitive, academic, behavioral, socio-affective, and adaptive consequences of early TBI. Four databases (Medline, PsycNET, CINAHL, PubMed) were systematically searched from 1990 to 2019 using key terms pertaining to TBI and early childhood. Of 12, 153 articles identified in the initial search, 43 were included. Children who sustain early TBI are at-risk for a range of difficulties, which are generally worse when injury is sustained at a younger age, injury severity is moderate to severe, and injury mechanisms are non-accidental. Early childhood is a sensitive period for the emergence and development of new skills and behaviors, and brain disruption during this time is not benign. Research, clinical management, intervention, and prevention efforts should be further developed with consideration of the unique characteristics of the early childhood period.

Abstract
BACKGROUND Disability and impaired health-related quality of life can persist for months among injured children. Previous studies of long-term outcomes have focused mainly on children with specific injury types rather than those with multiple injured body regions. This study's objective was to determine the long-term functional status and health-related quality of life after serious pediatric injury, and to evaluate the associations of these outcomes with features available at hospital discharge. STUDY DESIGN We conducted a prospective observational study at 7 Level I pediatric trauma centers of children treated for at least 1 serious (Abbreviated Injury Scale severity 3 or higher) injury. Patients were sampled to increase the representation of less frequently injured body regions and multiple injured body regions. Six-month functional status was measured using the Functional Status Scale (FSS) and health-related quality of life using the Pediatric Quality of Life Inventory. RESULTS Among 323 injured children with complete discharge and follow-up assessments, 6-month FSS score was abnormal in 33 patients (10.2%)-16 with persistent impairments and 17 previously normal at discharge. Increasing levels of impaired discharge FSS score were associated with impaired FSS and lower Pediatric Quality of Life Inventory scores at 6-month follow-up. Additional factors on multivariable analysis associated with 6-month FSS impairment included older age, penetrating injury type, severe head injuries, and spine injuries, and included older age for lower 6-month Pediatric Quality of Life Inventory scores. CONCLUSIONS Older age and discharge functional status are associated with long-term impairment of functional status and health-related quality of life. Although most seriously injured children return to normal, ongoing disability and reduced health-related quality of life remained 6 months after injury. Our findings support long-term assessments as standard practice for evaluating the health impacts of serious pediatric injury.

Abstract
Traumatic brain injury (TBI) during critical periods of early-life brain development can affect the normal formation of brain networks responsible for a range of complex social behaviors. Because of the protracted nature of brain and behavioral development, deficits in cognitive and socioaffective behaviors may not become evident until late adolescence and early adulthood, when such skills are expected to reach maturity. In addition, multiple pre- and post-injury factors can interact with the effects of early brain insult to influence long-term outcomes. In recent years, with advancements in magnetic-resonance-based neuroimaging techniques and analysis, studies of the pediatric population have revealed a link between neurobehavioral deficits, such as social dysfunction, with white matter damage. In this review, in which we focus on contributions from Australian researchers to the field, we have highlighted pioneering longitudinal studies in pediatric TBI, in relation to social deficits specifically. We also discuss the use of advanced neuroimaging and novel behavioral assays in animal models of TBI in the immature brain. Together, this research aims to understand the relationship between injury consequences and ongoing brain development after pediatric TBI, which promises to improve prediction of the behavioral deficits that emerge in the years subsequent to early-life injury.

Abstract
OBJECTIVE Rapid-sequence MRI (RSMRI) of the brain is a limited-sequence MRI protocol that eliminates ionizing radiation exposure and reduces imaging time. This systematic review sought to examine studies of clinical RSMRI use for pediatric traumatic brain injury (TBI) and to evaluate various RSMRI protocols used, including their reported accuracy as well as clinical and systems-based limitations to implementation. METHODS PubMed, EMBASE, and Web of Science databases were searched, and clinical articles reporting the use of a limited brain MRI protocol in the setting of pediatric head trauma were identified. RESULTS Of the 1639 articles initially identified and reviewed, 13 studies were included. An additional article that was in press at the time was provided by its authors. The average RSMRI study completion time was variable, spanning from 1 minute to 16 minutes. RSMRI with "blood-sensitive" sequences was more sensitive for detection of hemorrhage compared with head CT (HCT), but less sensitive for detection of skull fractures. Compared with standard MRI, RSMRI had decreased sensitivity for all evidence of trauma. CONCLUSIONS Protocols and uses of RSMRI for pediatric TBI were variable among the included studies. While traumatic pathology missed by RSMRI, such as small hemorrhages and linear, nondisplaced skull fractures, was frequently described as clinically insignificant, in some cases these findings may be prognostically and/or forensically significant. Institutions should integrate RSMRI into pediatric TBI management judiciously, relying on clinical context and institutional capabilities.

Abstract
OBJECTIVE To assess the burden of paediatric traumatic brain injury (TBI) on neurocognition via a systematic review and meta-analysis. METHODS Studies that compared neurocognitive outcomes of paediatric patients with TBI and controls were searched using Medline, Embase, PsycINFO and Cochrane Central Register of Controlled Trials, between January 1988 and August 2019. We presented a random-effects model, stratified by TBI severity, time of assessment post injury and age. RESULTS Of 5919 studies, 41 (patients=3717) and 33 (patients=3118) studies were included for the systematic review and meta-analysis, respectively. Studies mostly measured mild TBI (n=26, patients=2888) at 0-3 months postinjury (n=17, patients=2502). At 0-3 months postinjury, standardised mean differences between TBI and controls for executive function were -0.04 (95% CI -0.14 to 0.07; I2=0.00%), -0.18 (95% CI -0.29 to -0.06; I2=26.1%) and -0.95 (95% CI -1.12 to -0.77; I2=10.1%) for mild, moderate and severe TBI, respectively; a similar effect was demonstrated for learning and memory. Severe TBI had the worst outcomes across all domains and persisted >24 months postinjury. Commonly used domains differed largely from workgroup recommendations. Risk of bias was acceptable for all included studies. CONCLUSION A dose-dependent relationship between TBI severity and neurocognitive outcomes was evident in executive function and in learning and memory. Cognitive deficits were present for TBIs of all severity but persisted among children with severe TBI. The heterogeneity of neurocognitive scales makes direct comparison between studies difficult. Future research into lesser explored domains and a more detailed assessment of neurocognitive deficits in young children are required to better understand the true burden of paediatric TBI.

Abstract
Objective: Behavioral and emotional difficulties are reported following pediatric mild traumatic brain injury (TBI). But few studies have used a broad conceptual approach to examine children's long-term psychosocial outcomes. This study examines children's psychosocial outcomes at 4-years after mild TBI and associated factors.Methods: Parents of 93 children (<16 years) with mild TBI completed subscales of age-appropriate versions of the Strengths and Difficulties Questionnaire, the Behavior Rating Inventory of Executive Function, the Pediatric Quality of Life Inventory, and the Adolescent Scale of Participation questionnaire at 4-years post-injury.Results: Mean group-level scores were statistically significantly higher for hyperactivity/inattention and lower for emotional functioning than published norms. Levels of participation were greater compared to those observed in normative samples. More than 19% met published criteria for clinically significant hyperactivity/inattention, emotional functioning problems, peer relationship problems, and social functioning difficulties. Lower family socio-economic status and greater parental anxiety and depression were associated with overall psychosocial difficulties.Conclusions: Findings indicate that as a group, children with mild TBI are characterized by elevated rates of behavioral, emotional, and social difficulties at 4-years post-injury. Parent mental health may be an untapped opportunity to support children's psychosocial development following mild TBI, with replication required in larger samples.

Abstract
INTRODUCTION Mild traumatic brain injury (mTBI) is highly prevalent, especially in children under 6 years. However, little research focuses on the consequences of mTBI early in development. The objective of the Kids' Outcomes And Long-term Abilities (KOALA) study is to document the impact of early mTBI on children's motor, cognitive, social and behavioural functioning, as well as on quality of life, stress, sleep and brain integrity. METHODS AND ANALYSES KOALA is a prospective, multicentre, longitudinal cohort study of children aged 6 months to 6 years at the time of injury/recruitment. Children who sustain mTBI (n=150) or an orthopaedic injury (n=75) will be recruited from three paediatric emergency departments (PEDs), and compared with typically developing children (community controls, n=75). A comprehensive battery of prognostic and outcome measures will be collected in the PED, at 10 days, 1, 3 and 12 months postinjury. Biological measures, including measures of brain structure and function (magnetic resonance imaging, MRI), stress (hair cortisol), sleep (actigraphy) and genetics (saliva), will complement direct testing of function using developmental and neuropsychological measures and parent questionnaires. Group comparisons and predictive models will test the a priori hypotheses that, compared with children from the community or with orthopaedic injuries, children with mTBI will (1) display more postconcussive symptoms and exhibit poorer motor, cognitive, social and behavioural functioning; (2) show evidence of altered brain structure and function, poorer sleep and higher levels of stress hormones. A combination of child, injury, socioenvironmental and psychobiological factors are expected to predict behaviour and quality of life at 1, 3 and 12 months postinjury. ETHICS AND DISSEMINATION The KOALA study is approved by the Sainte-Justine University Hospital, McGill University Health Centre and University of Calgary Conjoint Health Research Ethics Boards. Parents of participants will provide written consent. Dissemination will occur through peer-reviewed journals and an integrated knowledge translation plan.

Abstract
This study investigated patterns of cortical organization in adolescents who had sustained a traumatic brain injury (TBI) during early childhood to determine ways in which early head injury may alter typical brain development. Increased gyrification in other patient populations is associated with polymicrogyria and aberrant development, but this has not been investigated in TBI. Seventeen adolescents (mean age = 14.1 ± 2.4) who sustained a TBI between 1-8 years of age, and 17 demographically-matched typically developing children (TDC) underwent a high-resolution, T1-weighted 3-Tesla magnetic resonance imaging (MRI) at 6-15 years post-injury. Cortical white matter volume and organization was measured using FreeSurfer's Local Gyrification Index (LGI). Despite a lack of significant difference in white matter volume, participants with TBI demonstrated significantly increased LGI in several cortical regions that are among those latest to mature in normal development, including left parietal association areas, bilateral dorsolateral and medial frontal areas, and the right posterior temporal gyrus, relative to the TDC group. Additionally, there was no evidence of increased surface area in the regions that demonstrated increased LGI. Higher Vineland-II Socialization scores were associated with decreased LGI in right frontal and temporal regions. The present results suggest an altered pattern of expected development in cortical gyrification in the TBI group, with changes in late-developing frontal and parietal association areas. Such changes in brain structure may underlie cognitive and behavioral deficits associated with pediatric TBI. Alternatively, increased gyrification following TBI may represent a compensatory mechanism that allows for typical development of cortical surface area, despite reduced brain volume.

Abstract
Childhood traumatic brain injury (TBI) commonly occurs during brain development and can have direct, immediately observable neurologic, cognitive, and behavioral consequences. However, it can also disrupt subsequent brain development, and long-term outcomes are a combination of preinjury development and abilities, consequences of brain injury, as well as delayed impaired development of skills that were immature at the time of injury. There is a growing number of studies on mild TBI/sport-related concussions, describing initial symptoms and their evolution over time and providing guidelines for effective management of symptoms and return to activity/school/sports. Mild TBI usually does not lead to long-term cognitive or academic consequences, despite reports of behavioral/psychologic issues postinjury. Regarding moderate to severe TBI, injury to the brain is more severe, with evidence of a number of detrimental consequences in various domains. Patients can display neurologic impairments (e.g., motor deficits, signs of cerebellar disorder, posttraumatic epilepsy), medical problems (e.g., endocrine pituitary deficits, sleep-wake abnormalities), or sensory deficits (e.g., visual, olfactory deficits). The most commonly reported deficits are in the cognitive-behavioral field, which tend to be significantly disabling in the long-term, impacting the development of autonomy, socialization and academic achievement, participation, quality of life, and later, independence and ability to enter the workforce (e.g., intellectual deficits, slow processing speed, attention, memory, executive functions deficits, impulsivity, intolerance to frustration). A number of factors influence outcomes following pediatric TBI, including preinjury stage of development and abilities, brain injury severity, age at injury (with younger age at injury most often associated with worse outcomes), and a number of family/environment factors (e.g., parental education and occupation, family functioning, parenting style, warmth and responsiveness, access to rehabilitation and care). Interventions should identify and target these specific factors, given their major role in postinjury outcomes. Abusive head trauma (AHT) occurs in very young children (most often <6 months) and is a form of severe TBI, usually associated with delay before appropriate care is sought. Outcomes are systematically worse following AHT than following accidental TBI, even when controlling for age at injury and injury severity. Children with moderate to severe TBI and AHT usually require specific, coordinated, multidisciplinary, and long-term rehabilitation interventions and school adaptations, until transition to adult services. Interventions should be patient- and family-centered, focusing on specific goals, comprising education about TBI, and promoting optimal parenting, communication, and collaborative problem-solving.

Abstract
OBJECTIVE Children treated in the pediatric intensive care unit (PICU) often face difficulties with long-term morbidities associated with neurologic injuries and lifesaving PICU interventions termed Post-Intensive Care Syndrome (PICS). In an effort to identify and address critical issues related to PICS, we developed an integrated model of care whereby children and families participate in follow-up clinics with a neuropsychologist and a critical care physician. To demonstrate preliminary impact, we present pilot findings on the early identification and treatment of PICS in a cohort of infants and young children in our program through a combination of multi-professional direct assessment and parent proxy questionnaires. METHOD Thirty-three infants and children, ages 3-72 months, participated in our initial follow-up clinic where issues related to physical health/recovery, development/cognition, mood/behavior, and quality of life were screened 1-3 months after discharge from the PICU. RESULTS In comparison to pre-hospitalization functioning, direct assessment revealed new neurological concerns identified by the critical care physician in 33.3% of participants and new neurocognitive concerns identified by the neuropsychologist in 36.4% of participants. Caregiver reported measures showed significant issues with patient cognitive functioning, emotional functioning, sleep, and impact on the family. Participants and families experienced significant difficulties related to changes in functioning and disability. Parents/caregivers and clinicians demonstrated agreement on functioning across a variety of indicators; however, important divergence in assessments were also found highlighting the importance of multiple assessments and perspectives. CONCLUSIONS New PICS morbidities are common in the early phase of recovery after discharge in infants, young children and their families. Results demonstrate the benefits and need for timely PICU follow-up care that involves collaboration/integration of physicians, neuropsychologists, and families to identify and treat PICS issues.

Abstract
Traumatic brain injury (TBI) can affect individuals at any age, with the potential of causing lasting neurologic consequences. The lack of effective therapeutic solutions and recommendations for patients that acquire a TBI can be attributed, at least in part, to an inability to confidently predict long-term outcomes following TBI, and how the response of the brain differs across the life span. The purpose of this study was to determine how age specifically affects TBI outcomes in a preclinical model. Male Thy1-YFPH mice, that express yellow fluorescent protein in the cytosol of a subset of Layer V pyramidal neurons in the neocortex, were subjected to a lateral fluid percussion injury over the right parietal cortex at distinct time points throughout the life span (1.5, 3, and 12 months of age). We found that the degree of neuronal injury, astrogliosis, and microglial activation differed depending on the age of the animal when the injury occurred. Furthermore, age affected the initial injury response and how it resolved over time. Using the microtubule stabilizing agent Epothilone D, to potentially protect against these pathologic outcomes, we found that the neuronal response was different depending on age. This study clearly shows that age must be taken into account in neurologic studies and preclinical trials involving TBI, and that future therapeutic interventions must be tailored to age.

Epidemiology of Pediatric Traumatic Brain Injury and Hypothalamic-Pituitary Disorders in Arizona. Front Neurol 2020; 10:1410. [PMID: 32038466 PMCID: PMC6988738 DOI: 10.3389/fneur.2019.01410] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2019] [Accepted: 12/24/2019] [Indexed: 01/25/2023] Open
Abstract
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.

Abstract
PURPOSE OF REVIEW To provide a summary of recent developments in the field of paediatric traumatic brain injury (TBI). RECENT FINDINGS The epidemiology of paediatric TBI with falling rates of severe TBI, and increasing presentations of apparently minor TBI. There is growing interest in the pathophysiology and outcomes of concussion in children, and detection of 'significant' injury, arising from concern about risks of long-term chronic traumatic encephalopathy. The role of decompressive craniectomy in children is still clarifying. SUMMARY Paediatric TBI remains a major public health issue.

Abstract
Objective: Social communication presents a significant difficulty for children with traumatic brain injury (TBI). Although several measures are used to examine social communication, there is no gold-standard assessment tool. The present pilot study examined the ability of the Social Communication Disorders Checklist (SCDC) to detect social communication difficulties in pediatric TBI. Further, we examined the relationship between social communication and social functioning as assessed by parental ratings of behavior and objective measures of social cognition. Methods: Sixteen children with pediatric TBI and 20 age, education and sex matched healthy controls (HCs) participated. All participants participated in a neuropsychological evaluation and parents filled out questionnaires. Parents rated their children's social communication abilities using the SCDC, as well as the Behavior Assessment System for Children, Second Edition (BASC-2). The pediatric subjects completed a task of social cognition, specifically Theory of Mind (ToM). Results: The pediatric TBI group had significantly lower scores on the SCDC compared to the HCs (p = 0.001). In the pediatric group, SCDC scores correlated significantly with scores on the BASC-2, as well as performance on the ToM task, indicating that children with lower parent-rated social communication abilities also had lower scores on the objective measure of social cognition. Conclusions: These data provide preliminary evidence that children with TBI have difficulties with social communication, as evidenced by lower scores on the SCDC, and that SCDC scores correlate with subjective and objective measures of social cognition and behavior in pediatric TBI.

Characterisation of serum total tau following paediatric traumatic brain injury: a case-control study. THE LANCET CHILD & ADOLESCENT HEALTH 2019; 3:558-567. [PMID: 31231066 DOI: 10.1016/s2352-4642(19)30194-4] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/18/2019] [Revised: 04/19/2019] [Accepted: 04/24/2019] [Indexed: 12/29/2022]
Abstract
BACKGROUND Traumatic brain injury (TBI) is a major health problem in children. Blood-based biomarkers interpreted by use of normative values might improve the accuracy of diagnosis. Ultrasensitive assays can quantify serum concentrations of the neuronal microtubule-associated protein tau, which is increased in adult brains following TBI. We aimed to determine if serum total tau correlates with TBI diagnosis, severity, and radiological findings on CT scans in children younger than 18 years. METHODS In this case-control study, we included venous blood samples from healthy control children in the Canadian Laboratory Initiative on Pediatric Reference Intervals (CALIPER) biobank. For TBI cases, we recruited children (aged 0-17 years) who presented to the emergency department within 24 h of a TBI in three tertiary-care paediatric hospitals (Toronto, Vancouver, and Melbourne). Children were eligible if they required hospital observation for a minimum of 4 h or admission to the intensive care unit, and were excluded if they had had hospital treatment for a previous TBI, had birth trauma, or their parents could not speak English or French and therefore could not readily give consent. All available control samples were used and a case-control match was therefore not done. Venous and arterial blood samples were collected from patients with TBI within 28 h of injury (day 1). We used an ultrasensitive single-molecule immunoassay to measure serum total tau in blood samples. We first generated reference intervals of serum total tau from the control group, and used these normative data to interpret injury-associated changes in serum total tau in children with TBI. Concentrations of serum tau were measured in all CALIPER participants and patients with TBI, and no participants were excluded before analysis. FINDINGS We included samples from 416 control participants from the CALIPER cohort. Median total tau concentrations did not differ between sexes (p=0·12), but three significant reference intervals based on age groups were identified (1-3 years [0·88-19·2 pg/mL], 4-15 years [0·93-5·31 pg/mL], and 16-19 years [0·79-4·20 pg/mL]). Blood samples were obtained from 158 patients with TBI recruited between April 30, 2011, and June 28, 2013. Serum total tau on day 1 of TBI was negatively associated with Glasgow Coma Scale (GCS) score (rs=-0·42, 95% CI -0·55 to -0·28, p<0·0001). Median total tau was 2·86 pg/mL (IQR 1·52-4·83) in patients with GCS score 13-15 points (n=114), 7·08 pg/mL (3·75-41·1) in those with GCS score 9-12 points (n=13), and 8·48 pg/mL (2·53-70·6) in those with GCS score 3-8 points (n=31). Notably, participants who had GCS scores of 15 points had median total tau concentrations (2·57 pg/mL [1·50-4·61]) indistinguishable from those of control participants (2·46 pg/mL [1·77-3·42]), whereas those with GCS score 13-14 points had elevated total tau (6·41 pg/mL [2·97-42·5]). Serum total tau was not strongly associated with CT findings in patients with mild TBI. INTERPRETATION Serum total tau might help to differentiate between patients with mild TBI (GCS 13-14 vs GCS 15), but larger studies are needed to validate these results before this biomarker can be used for diagnosis and prognosis.

Abstract
Pediatric traumatic brain injury (TBI) remains a leading cause of childhood morbidity and mortality worldwide. Most efforts to reduce the chronic impact of pediatric TBI involve prevention and minimization of secondary injury. Currently, no treatments are used in routine clinical care during the acute and subacute phases to actively repair injury to the developing brain. The endogenous pluripotent cytokine erythropoietin (EPO) holds promise as an emerging neuroreparative agent in perinatal brain injury (PBI). EPO signaling in the central nervous system (CNS) is essential for multiple stages of neurodevelopment, including the genesis, survival and differentiation of multiple lineages of neural cells. Postnatally, EPO signaling decreases markedly as the CNS matures. Importantly, high-dose, extended EPO regimens have shown efficacy in preclinical controlled cortical impact (CCI) models of infant TBI at two different, early ages by independent research groups. Specifically, extended high-dose EPO treatment after infantile CCI prevents long-term cognitive deficits in adult rats. Because of the striking differences in the molecular and cellular responses to both injury and recovery in the developing and mature CNS, and the excellent safety profile of EPO in infants and children, extended courses of EPO are currently in Phase III trials for neonates with PBI. Extended, high-dose EPO may also warrant testing for infants and young children with TBI.

Abstract
Traumatic brain injury is the leading cause of death and disability in the United States, and may be associated with long lasting impairments into adulthood. The multitude of ongoing neurobiological processes that occur during brain maturation confer both considerable vulnerability to TBI but may also provide adaptability and potential for recovery. This review will examine and synthesize our current understanding of developmental neurobiology in the context of pediatric TBI. Delineating this biology will facilitate more targeted initial care, mechanism-based therapeutic interventions and better long-term prognostication and follow-up.
