RESUMEN
BACKGROUND: Predicting recovery following pediatric mild traumatic brain injury (mTBI) remains challenging. The identification of objective biomarkers for prognostic purposes could improve clinical outcomes. Telomere length (TL) has previously been used as a prognostic marker of cellular health in the context of mTBI and other neurobiological conditions. While psychosocial and environmental factors are associated with recovery outcomes following pediatric mTBI, the relationship between these factors and TL has not been investigated. This study sought to examine the relationships between TL and psychosocial and environmental factors, in a cohort of Canadian children with mTBI or orthopedic injury (OI). METHODS: Saliva was collected at a postacute (median 7 days) timepoint following injury to assess TL from a prospective longitudinal cohort of children aged 8 to 17 years with either mTBI (n = 202) or OI (n = 90), recruited from 3 Canadian sites. Questionnaires regarding psychosocial and environmental factors were obtained at a postacute follow-up visit and injury outcomes were assessed at a 3-month visit. Univariable associations between TL and psychosocial, environmental, and outcome variables were assessed using Spearman's correlation. Further adjusted analyses of these associations were performed by including injury group, age, sex, and site as covariates in multivariable generalized linear models with a Poisson family, log link function, and robust variance estimates. RESULTS: After adjusting for age, sex, and site, TL in participants with OI was 7% shorter than those with mTBI (adjusted mean ratio = 0.93; 95% confidence interval, 0.89-0.98; P = .003). As expected, increasing age was negatively associated with TL (Spearman's r = -0.14, P = .016). Sleep hygiene at 3 months was positively associated with TL (adjusted mean ratio = 1.010; 95% confidence interval, 1.001-1.020; P = .039). CONCLUSION: The relationships between TL and psychosocial and environmental factors in pediatric mTBI and OI are complex. TL may provide information regarding sleep quality in children recovering from mTBI or OI; however, further investigation into TL biomarker validity should employ a noninjured comparison group.
RESUMEN
BACKGROUND AND PURPOSE: Microstructural white matter abnormalities on DTI using Tract-Based Spatial Statistics at term-equivalent age are associated with cognitive and motor outcomes at 2 years of age or younger. However, neurodevelopmental tests administered at such early time points are insufficiently predictive of mild-moderate motor and cognitive impairment at school age. Our objective was to evaluate the microstructural antecedents of cognitive and motor outcomes at 3 years' corrected age in a cohort of very preterm infants. MATERIALS AND METHODS: We prospectively recruited 101 very preterm infants (<32 weeks' gestational age) and performed DTI at term-equivalent age. The Differential Ability Scales, 2nd ed, Verbal and Nonverbal subtests, and the Bayley Scales of Infant and Toddler Development, 3rd ed, Motor subtest, were administered at 3 years of age. We correlated DTI metrics from Tract-Based Spatial Statistics with the Bayley Scales of Infant and Toddler Development, 3rd ed, and the Differential Ability Scales, 2nd ed, scores with correction for multiple comparisons. RESULTS: Of the 101 subjects, 84 had high-quality DTI data, and of these, 69 returned for developmental testing (82%). Their mean (SD) gestational age was 28.4 (2.5) weeks, and birth weight was 1121.4 (394.1) g. DTI metrics were significantly associated with Nonverbal Ability in the corpus callosum, posterior thalamic radiations, fornix, and inferior longitudinal fasciculus and with Motor scores in the corpus callosum, internal and external capsules, posterior thalamic radiations, superior and inferior longitudinal fasciculi, cerebral peduncles, and corticospinal tracts. CONCLUSIONS: We identified widespread microstructural white matter abnormalities in very preterm infants at term that were significantly associated with cognitive and motor development at 3 years' corrected age.

BACKGROUND: Deficits in social cognition may be among the most profound and disabling sequelae of paediatric traumatic brain injury (TBI); however, the neuroanatomical correlates of longitudinal outcomes in this domain remain unexplored. This study aimed to characterize social cognitive outcomes longitudinally after paediatric TBI, and to evaluate the use of sub-acute diffusion tensor imaging (DTI) to predict these outcomes. METHODS: The sample included 52 children with mild complex-severe TBI who were assessed on cognitive theory of mind (ToM), pragmatic language and affective ToM at 6- and 24-months post-injury. For comparison, 43 typically developing controls (TDCs) of similar age and sex were recruited. DTI data were acquired sub-acutely (mean = 5.5 weeks post-injury) in a subset of 65 children (TBI = 35; TDC = 30) to evaluate longitudinal prospective relationships between white matter microstructure assessed using Tract-Based Spatial Statistics and social cognitive outcomes. RESULTS: Whole brain voxel-wise analysis revealed significantly higher mean diffusivity (MD), axial diffusivity (AD) and radial diffusivity (RD) in the sub-acute TBI group compared with TDC, with differences observed predominantly in the splenium of the corpus callosum (sCC), sagittal stratum (SS), dorsal cingulum (DC), uncinate fasciculus (UF) and middle and superior cerebellar peduncles (MCP & SCP, respectively). Relative to TDCs, children with TBI showed poorer cognitive ToM, affective ToM and pragmatic language at 6-months post-insult, and those deficits were related to abnormal diffusivity of the sCC, SS, DC, UF, MCP and SCP. Moreover, children with TBI showed poorer affective ToM and pragmatic language at 24-months post-injury, and those outcomes were predicted by sub-acute alterations in diffusivity of the DC and MCP. CONCLUSIONS: Abnormal microstructure within frontal-temporal, limbic and cerebro-cerebellar white matter may be a risk factor for long-term social difficulties observed in children with TBI. DTI may have potential to unlock early prognostic markers of long-term social outcomes.

Child behavior problems, injury-related family burden, and parent psychological distress were assessed longitudinally over the first year post injury in 40 children with severe traumatic brain injury (TBI), 52 with moderate TBI, and 55 with orthopedic injuries not involving brain insult. Parents rated children's preinjury behavior soon after injury. Postinjury child behavior and family outcomes were assessed at 6- and 12-month follow-ups. Findings from path analysis revealed both direct and indirect effects of TBI on child behavior and family outcomes, as well as cross-lagged child-family associations. Higher parent distress at 6 months predicted more child behavior problems at 12 months, controlling for earlier behavior problems; and more behavior problems at 6 months predicted poorer family outcomes at 12 months, controlling for earlier family outcomes. Support for bidirectional influences is tentative given that limited sample size precluded use of structural equation modeling. The findings nevertheless provide impetus for considering the influences of person-environment interactions on outcomes of TBI.

This study identified coping strategies associated with caregiver outcomes following pediatric injury and examined injury type as a moderator of coping efficacy. Families of 103 children with traumatic brain injury (TBI) and 71 children with orthopedic injuries were followed prospectively during the initial year postinjury. The groups had comparable preinjury characteristics and hospitalization experiences but differed on neurological insult. In hierarchical regression analyses, acceptance was associated with lower burden and denial was associated with greater distress in both groups. Active coping resulted in higher distress following TBI but not orthopedic injuries. Conversely, the use of humor was related to diminishing distress following TBI but unrelated to distress following orthopedic injuries. Results are discussed in terms of the implications for intervention following TBI.

BACKGROUND: Previous findings indicate that pediatric fractures can have adverse consequences for child adjustment and family functioning immediately after injury. However, longer term effects of the fractures are unknown. The purposes of the present prospective study were to examine the child and family outcomes of pediatric traumatic fractures at 6 months and 1 year after injury, and to identify injury and treatment factors associated with these outcomes. METHODS: We evaluated 57 children 6 to 12 years of age with traumatic fractures requiring hospitalization. Using standardized measures and parent interview, we obtained measures of pre- and postinjury child and family functioning. RESULTS: Although outcomes were primarily positive at 1 year after injury, child functional limitations and family stress were observed up to 6 months after injury. Lower extremity fractures had a more negative impact on families across all three assessment points. Children with fracture interventions that involved prolonged immobilization had more functional limitations at 6 months than children who were ambulatory. Family burden was higher at 1 month for the immobilized children, but not at later follow-up. CONCLUSION: Some children and families experience adverse effects during the year after a serious pediatric fracture, especially if sustained in a lower extremity. Fracture stabilization that allows for greater ambulation may offer some benefits related to functional outcomes and family impact.

The prevalence and correlates of depressive symptoms following childhood traumatic brain injuries (TBI) were examined using data drawn from a prospective longitudinal study. Participants included 38 children with severe TBI, 51 with moderate TBI, and 55 with orthopedic injuries (OI). Assessments occurred shortly after injury (baseline) and at 6- and 12-month follow-ups. Children completed the Child Depression Inventory (CDI). Parents rated depressive symptoms using the Child Behavior Checklist (CBC), with baseline ratings reflecting premorbid status. Assessments also included measures of children's neurocognitive functioning and the family environment. The three groups did not differ overall in self-reported symptoms on the CDI, but did display different trends over time. The three groups did not differ on parent ratings of premorbid depressive symptoms on the CBC, but parents reported more depressive symptoms in the TBI groups than in the OI group at 6- and 12-month follow-ups. Child and parent reports were correlated for children in the TBI groups, but not for those in the OI group. Depressive symptoms were related to socioeconomic status in all groups. Socioeconomic status also was a significant moderator of group differences, such that the effects of TBI were exacerbated in children from more disadvantaged homes. Although self-reports of depressive symptoms were related inconsistently to children's verbal memory, parent reports of depressive symptoms were unrelated to IQ or verbal memory. The findings suggest that TBI increases the risk of depressive symptoms, especially among more socially disadvantaged children, and that depressive symptoms are not strongly related to post-injury neurocognitive deficits.

OBJECTIVE: To examine the incidence and neuropsychological, behavioral, and neuroimaging correlates of postconcussive symptoms (PCS) in children with mild closed head injuries (CHI). DESIGN: 26 Children with mild CHI and 8 of their uninjured siblings, from 8 to 15 years old, were recruited prospectively and assessed at baseline (ie, within 7 days of injury) and at 3 months postinjury. Parents rated PCS, motivation and affective lability, and behavioral adjustment. Baseline ratings assessed premorbid functioning retrospectively, and follow-up ratings assessed postinjury status. On both occasions, children completed neuropsychological testing, and those with mild CHI also underwent magnetic resonance imaging (MRI). RESULTS: Children with mild CHI did not differ from siblings in baseline ratings of premorbid PCS but displayed higher ratings on several PCS at 3 months postinjury. Thirty-five percent of children with mild CHI showed increases in PCS, compared with baseline premorbid ratings, but none of the siblings did so. Children with mild CHI whose PCS increased from premorbid levels showed poorer neuropsychological functioning at baseline than did children whose PCS did not increase, although the differences had partially resolved by 3 months. They also displayed decreased motivation over time. Their behavioral adjustment was poorer and they had smaller white matter volumes on MRI, but the latter differences were present at baseline and did not change over time, suggesting that they existed prior to the injury. CONCLUSION: Postinjury increases in PCS occur in a sizable minority of children with mild CHI and more often than among uninjured siblings. Increases in PCS following mild CHI are associated with premorbid neurological and psychosocial vulnerability, but also with postinjury decrements in neuropsychological and neurobehavioral functioning.

OBJECTIVE: To assess the reliability and validity of a new instrument, the Family Burden of Injury Interview (FBII) was designed to assess the impact of childhood traumatic head injuries (THI) on the family. PARTICIPANTS: 99 Mothers of school-age children who experienced THI. RESULTS: The FBII Total Score revealed group differences between families of children with severe THI and families of children with moderate THI. The measure also showed concurrent and predictive relationships to measures of the general impact of injury on families and maternal and child functioning. CONCLUSION: The FBII is a promising tool for measuring the impact of injury-related stressors on the family.

Examined posttraumatic stress (PTS) symptoms in children following pediatric traumatic brain injury (TBI). Children (ages 6-12) with TBI (n = 81) and orthopedic injury (OI; n = 59) were assessed 6 and 12 months postinjury. Parents of children with severe TBI reported higher levels of child PTS symptoms than did parents of children with moderate TBI or OI at the 6- and 12-month follow-ups. Group differences in child-reported PTS symptoms emerged at the 12-month follow-up with higher symptom levels reported by children with severe TBI than by those with moderate TBI or OI. At both follow-ups, rates of clinically significant symptom levels were higher in the severe TBI group than in the moderate TBI or OI groups. The group differences in parent and child reports were significant even after taking ethnicity, social disadvantage, and age at injury into account. Parent and child reports of child PTS symptoms were related to family socioeconomic status. Implications for clinical intervention with children and families following pediatric TBI are discussed.

This study examined recovery over the first year following traumatic brain injury (TBI) in children 6-12 years of age. Forty-two children with severe TBI and 52 with moderate TBI were compared to 58 children with orthopedic injuries. The children and their families were evaluated at a baseline assessment and at 6- and 12-month follow-ups. Findings documented cognitive, achievement, and behavioral sequelae of TBI, with only limited evidence for recovery over the first year postinjury. Outcomes were predicted by preinjury factors, TBI severity, and measures of the postinjury family environment. Some of the sequelae of severe TBI were more marked in the context of higher compared with lower levels of family burden or dysfunction. The findings confirm the need to consider environmental contributions to outcomes of TBI in children.

BACKGROUND: The acute psychosocial effects of orthopedic injuries on children and their families are poorly understood. Previous studies have relied on retrospective reports or failed to take into account accompanying brain injuries. The purpose of the present study was to examine prospectively the psychosocial impact of pediatric orthopedic traumatic fractures with and without accompanying brain injuries. METHODS: Participants were 108 children 6 to 12 years old with orthopedic injuries requiring hospitalization: group 1 (n=80) had fractures only, group 2 (n=28) also had moderate or severe brain injuries. Using standardized measures and parent interviews, we obtained preinjury estimates of family functioning and child behavior problems and postinjury measures of parental distress, family stresses, and child behavior. RESULTS: Parents reported significant clinical distress (35% in group 1, 57% in group 2), family burdens (group 2 > group 1), and child behavioral changes (41% in group 1, 89% in group 2). Multiple regression analyses indicated that preinjury family status and brain injuries predicted postinjury parental and family distress. CONCLUSION: Pediatric orthopedic injuries have greater social effects on children with accompanying brain injuries and poorer preinjury family functioning.

Children and adolescents with traumatic brain injury (TBI) were compared to a matched sample of neurologically normal children and adolescents on several measures of cognitive processing. Each of the children in the TBI group had experienced a closed head injury of moderate to severe magnitude. Participants in both the TBI (n = 22) and control (n = 22) groups ranged in age from 9 to 17 years and lived in the midwestern United States. They were all administered the Cognitive Assessment System (Naglieri & Das, 1997a). Children with TBI earned significantly lower scores in the domains of Planning and Attention than the matched control group. Within-group comparisons showed that the TBI group s Planning and Attention scores were significantly lower than their Simultaneous and Successive scores. The results are consistent with previous literature demonstrating poor performance on measures of attention and executive functions among children who have experienced TBI.

OBJECTIVE: Traumatic brain injury (TBI) often leads to long-term behavioral and cognitive deficits in children. However, little is known about the burden and psychosocial morbidity of pediatric TBI for families. The purpose of this study was to test the hypothesis that moderate and severe TBI in children has more adverse consequences than orthopedic trauma. DESIGN: The sample was comprised of children between the ages of 6 and 12 recruited from hospital trauma and inpatient units including 53 with severe TBI, 56 with moderate TBI, and 80 with orthopedic injuries not involving central nervous system insult. Measures of injury-related burden, parental distress, and family functioning were administered to the child's primary caregiver at baseline assessment conducted soon after injury and at 6- and 12-month follow-ups. Multivariate repeated measures analysis of covariance was used to examine group differences in these outcomes over time. RESULTS: Caregivers in the severe TBI group reported significantly higher levels of family burden, injury-related stress, and parental psychological symptoms than caregivers in the orthopedic injury group (ORTHO). The groups did not differ with respect to marital distress. Caregivers in the severe TBI group were significantly more likely than caregivers in the ORTHO group to exceed the clinical cutoff on the Brief Symptom Inventory and to report clinically significant levels of family dysfunction at follow-up. CONCLUSIONS: The findings suggest that severe TBI is a source of considerable caregiver morbidity, even when compared with other traumatic injuries. Caregivers in the severe TBI group had persistent stress associated with the child's injury, as well as the reactions of other family members, and a relative risk of clinically significant psychological symptoms nearly twice that of the ORTHO comparison group. These findings underscore the need for interventions that facilitate family adaptation after pediatric TBI.

This study examined neuropsychological performance by 92 children with Tourette's syndrome (TS) grouped by the presence or absence of obsessive-compulsive and/or attention deficit symptoms. The identified groups did not differ with respect to age, education, age at onset of TS symptoms, or medication use. After statistical control for complex motor symptoms, impaired performance on measures of achievement and executive functioning was correlated with obsessive and obsessive/attention symptoms, but not with attention symptoms alone. The presence of both obsessive and attention symptoms identified children with impairment across several tasks. Clinical and functional implications are discussed.

Previous studies of childhood traumatic brain injury (TBI) have emphasized injury-related variables rather than environmental factors as predictors of recovery. We addressed this concern using data collected during a prospective study of children with either TBI or orthopedic injuries (OI) and their families. Participants included 53 children with severe TBI, 56 with moderate TBI, and 80 with OI, all from 6 to 12 years of age at the time of injury. Measures of the preinjury family environment were collected shortly after the injury (baseline). Child cognitive and behavioral outcomes were assessed at baseline and at 6- and 12-month follow-ups. Individual growth curve analyses showed that measures of the preinjury family environment consistently predicted both the level of cognitive and behavioral functioning at 12 months postinjury and the rate of intraindividual change during the 12-month follow-up period, even after taking into account group membership and injury severity. In some cases, the preinjury family environment was a significant moderator of the effect of TBI, buffering its impact in high-functioning families and exacerbating it in low-functioning families. Thus, preinjury environmental factors predict recovery following TBI in children, even after accounting for injury-related variables.

This study examined the prediction of premorbid neuropsychological functioning using data from an ongoing prospective study of traumatic brain injuries (TBI) in children ages 6 to 12 years. Prediction equations were derived based on 80 children with orthopedic injuries (OI), who served as a comparison group for the children with TBI. Collectively, parent ratings of premorbid school performance, maternal ethnicity, family socioeconomic status, and children's word recognition skill predicted from 13% to 45% of the variance in three measures of neuropsychological functioning. The regression equations were used to compute predicted scores among 109 children with TBI. Actual scores fell significantly below predicted scores among children with TBI, and the magnitude of the deficits was correlated with injury severity. Premorbid neuropsychological functioning can be predicted in children with TBI, but with less precision than would be desirable for clinical purposes.

Traumatic brain injury (TBI) is a significant source of morbidity and mortality in children, resulting in a wide range of cognitive and behavioral sequelae. However, little is known about the effects of pediatric TBI and its aftermath on families. The current investigation examined the impact of TBI on families during the first month following injury. Children with orthopedic injuries requiring hospitalization served as a control group. The sample consisted of 44 families of children of severe TBI, 52 families of children with moderate TBI, and 69 families of children with orthopedic injuries not involving the central nervous system (CNS). Families of children with severe TBI experienced significantly more injury-related stress than the other two groups of families. Parents of children with TBI also reported higher levels of psychological symptoms than parents of children with orthopedic injuries. Findings from regression analyses suggested that families facing multiple stressors in addition to the injury and those who cope poorly may be at greatest risk for adverse consequences. Future interventions could provide anticipatory guidance and support to at-risk families.

Neuropsychological deficits in Tourette's syndrome (TS) may be associated with learning disabilities. We examined the neuropsychological performance of 70 children with TS between the ages 6 and 18 years who were classified into four groups based on their pattern of performance on the Wide Range Achievement Test-Revised. The groups included three learning disability subtypes and a nonlearning disabled comparison group. The groups differed significantly on several measures in a comprehensive neuropsychological test battery. The pattern of differences was not entirely consistent with previous research, however, suggesting that neuropsychological correlates of learning disabilities may be influenced by the specific pathophysiology associated with TS. Thus, previous research on the neuropsychology of learning disability subtypes might not be generalizable to children with discrete neuropsychiatric disorders such as TS.

OBJECTIVE: Treatment of IDDM in youth emphasized balancing children's self-care autonomy with their psychological maturity. However, few data exist to guide clinicians or parents, and little is known about correlates of deviations from this ideal. RESEARCH DESIGN AND METHODS: In this cross-sectional study, IDDM self-care autonomy of 100 youth was assessed using two well-validated measures. Three measures of psychological maturity (cognitive function, social-cognitive development, and academic achievement) were also collected for each child. Composite indexes of self-care autonomy and of psychological maturity were formed, and the ratio of the self-care autonomy index to the psychological maturity index quantified each child's deviation from developmentally appropriate IDDM self-care autonomy. Based on these scores, participants were categorized as exhibiting constrained (lower tertile), appropriate (middle tertile), or excessive (higher tertile) self-care autonomy. Between-group differences in treatment adherence, diabetes knowledge, glycemic control, and hospitalization rates were explored. RESULTS: Analysis of covariance controlling for age revealed that the excessive self-care autonomy group demonstrated less favorable treatment adherence, diabetes knowledge, hospitalization rates, and, marginally, glycemic control. Excessive self-care autonomy increased with age and was less common among intact two-parent families but was unrelated to other demographic factors. CONCLUSIONS: The findings indicate caution about encouragement of maximal self-care autonomy among youth with IDDM and suggest that families who succeed in maintaining parental involvement in diabetes management may have better outcomes.
