Comparative effectiveness of improvement in pain and physical function for baricitinib versus adalimumab, tocilizumab and tofacitinib monotherapies in rheumatoid arthritis patients who are naïve to treatment with biologic or conventional synthetic disease-modifying antirheumatic drugs: a matching-adjusted indirect comparison.

OBJECTIVE: To compare improvement in pain and physical function for patients treated with baricitinib, adalimumab, tocilizumab and tofacitinib monotherapy from randomised, methotrexate (MTX)-controlled trials in conventional synthetic disease-modifying antirheumatic drugs (csDMARDs)/biologic (bDMARD)-naïve RA patients using matching-adjusted indirect comparisons (MAICs). METHODS: Data were from Phase III trials on patients receiving monotherapy baricitinib, tocilizumab, adalimumab, tofacitinib or MTX. Pain was assessed using a visual analogue scale (0-100 mm) and physical function using the Health Assessment Questionnaire-Disability Index (HAQ-DI). An MAIC based on treatment-arm matching, an MAIC with study-level matching and Bucher's method without matching compared change in outcomes between therapies. Matching variables included age, gender, baseline disease activity and baseline value of outcome measure. RESULTS: With all methods, greater improvements were observed in pain and HAQ-DI at 6 months for baricitinib compared with adalimumab and tocilizumab (p<0.05). Differences in treatment effects (TEs) favouring baricitinib for pain VAS for treatment-arm matching, study-level matching and Bucher's method, respectively, were -12, -12 and -12 for baricitinib versus adalimumab and -7, -7 and -9 for baricitinib versus tocilizumab; the difference in TEs for HAQ-DI was -0.28, -0.28 and -0.30 for adalimumab and -0.23, -0.23 and -0.26 for tocilizumab. For baricitinib versus tofacitinib, no statistically significant differences for pain improvement were observed except with one of the three methods (Bucher method) and none for HAQ-DI. CONCLUSIONS: Results suggest greater pain reduction and improved physical function for baricitinib monotherapy compared with tocilizumab and adalimumab monotherapy. No statistically significant differences in pain reduction and improved physical function were observed between baricitinib and tofacitinib with the MAIC analyses.

Home Environment as a Predictor of Long-Term Executive Functioning following Early Childhood Traumatic Brain Injury.

OBJECTIVES: This study examined the relationship of the home environment to long-term executive functioning (EF) following early childhood traumatic brain injury (TBI). METHODS: Participants (N=134) were drawn from a larger parent study of 3- to 6-year-old children hospitalized for severe TBI (n=16), complicated mild/moderate TBI (n=44), or orthopedic injury (OI; n=74), recruited prospectively at four tertiary care hospitals in the United States and followed for an average of 6.8 years post-injury. Quality of the home environment, caregiver psychological distress, and general family functioning were assessed shortly after injury (i.e., early home) and again at follow-up (i.e., late home). Participants completed several performance-based measures of EF at follow-up. Hierarchical regression analyses examined the early and late home environment measures as predictors of EF, both as main effects and as moderators of group differences. RESULTS: The early and late home environment were inconsistent predictors of long-term EF across groups. Group differences in EF were significant for only the TEA-Ch Walk/Don't Walk subtest, with poorer performance in the severe TBI group. However, several significant interactions suggested that the home environment moderated group differences in EF, particularly after complicated mild/moderate TBI. CONCLUSIONS: The home environment is not a consistent predictor of long-term EF in children with early TBI and OI, but may moderate the effects of TBI on EF. The findings suggest that interventions designed to improve the quality of stimulation in children's home environments might reduce the long-term effects of early childhood TBI on EF.

Neural substrates of inhibitory and emotional processing in adolescents with traumatic brain injury.

PURPOSE: Disturbances of emotional regulation and social difficulties are common in children and adolescents with traumatic brain injury (TBI). Recent research suggests that developments within ``socio-emotional'' brain systems during early adolescence and more protracted development of "cognitive control'' systems have implications for emotional and behavioral regulation during adolescence. However, few functional neuroimaging studies have directly examined the interaction of these neuropsychological processes in adolescents with TBI. The current study examined how affective processing might modulate inhibitory processing in an Emotional Go/NoGo paradigm. METHOD: The study uses a cross-sectional, age, gender, and maternal education matched design.A response inhibition paradigm (i.e., the Go/NoGo task with emotional faces) was used to examine emotional-cognition interaction in 11 adolescents with complicated mild to moderate TBI, at least 12 months post injury, and 14 typically-developing (TD) adolescents using functional magnetic resonance imaging (fMRI). Participants saw adult facial expressions of emotions (happy, sad, fearful, and angry) and were instructed to respond (``go'') on all expressions other than angry (``no-go''). RESULTS: Preliminary results (p= 0.001 uncorrected, cluster size = 50) showed higher levels of inhibition-related activation in TD adolescents than in adolescents with TBI in several brain regions including anterior cingulate and motor/premotor regions. CONCLUSION: These results suggest that TBI in adolescence might alter brain activation patterns and interrupt the development of brain networks governing emotion-cognition interactions.

The use of Lean and Six Sigma methodologies in surgery: a systematic review.

BACKGROUND: Lean and Six Sigma are improvement methodologies developed in the manufacturing industry and have been applied to healthcare settings since the 1990 s. They use a systematic and reproducible approach to provide Quality Improvement (QI), with a flexible process that can be applied to a range of outcomes across different patient groups. This review assesses the literature with regard to the use and utility of Lean and Six Sigma methodologies in surgery. METHODS: MEDLINE, Embase, PsycINFO, Allied and Complementary Medicine Database, British Nursing Index, Cumulative Index to Nursing and Allied Health Literature, Health Business Elite and the Health Management Information Consortium were searched in January 2014. Experimental studies were included if they assessed the use of Lean or Six Sigma on the ability to improve specified outcomes in surgical patients. RESULTS: Of the 124 studies returned, 23 were suitable for inclusion with 11 assessing Lean, 6 Six Sigma and 6 Lean Six Sigma. The broad range of outcomes can be collated into six common aims: to optimise outpatient efficiency, to improve operating theatre efficiency, to decrease operative complications, to reduce ward-based harms, to reduce mortality and to limit unnecessary cost and length of stay. The majority of studies (88%) demonstrate improvement; however high levels of systematic bias and imprecision were evident. CONCLUSION: Lean and Six Sigma QI methodologies have the potential to produce clinically significant improvement for surgical patients. However there is a need to conduct high-quality studies with low risk of systematic bias in order to further understand their role.

Utilization of behavioral therapy services long-term after traumatic brain injury in young children.

OBJECTIVE: To examine associations of clinical need, defined by elevated parent ratings of child behavior problems and utilization of behavioral health services in young children with traumatic brain injury (TBI) and an orthopedic injury (OI) comparison group. DESIGN: Parents completed outcome measures 18 months after injury and at an extended follow-up conducted an average of 38 months postinjury. SETTING: Children's hospitals and a general hospital. PARTICIPANTS: Participants included parents of 3 groups of children injured between 3 and 7 years of age (N=139): 47 children with complicated mild to moderate TBI, 18 with severe TBI, and 74 with OI. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Parents completed ratings of child behavior, mental health symptomology, and family functioning at both visits; at the extended follow-up, they reported utilization of behavior therapy or counseling services since the 18-month follow-up visit. RESULTS: Children with TBI had more behavior problems than those with OI. Although clinical need at both follow-ups was associated with greater service utilization at the extended follow-up, all groups had unmet needs as defined by a clinical need in the absence of services. Lower socioeconomic status was associated with higher rates of unmet need across groups. CONCLUSIONS: The results document unmet long-term behavioral health needs after both TBI and OI in children and underscore the importance of monitoring and treatment of postinjury behavior problems.

Sleep problems and their relationship to cognitive and behavioral outcomes in young children with traumatic brain injury.

This study examined the effect of traumatic brain injury (TBI) in young children on sleep problems and the relationship of sleep problems to neuropsychological and psychosocial functioning. Participants were drawn from an ongoing longitudinal study of injury in young children recruited from 3 to 6 years of age. They constituted three groups: orthopedic injury (OI; n=92), complicated mild/moderate TBI (mTBI; n=55); and severe TBI (sTBI; n=20). Caregivers completed the Children's Sleep Habits Questionnaire (CSHQ), as well as ratings of behavioral adjustment, adaptive functioning, and everyday executive function at 1, 6, 12, and 18 months postinjury. Retrospective ratings of preinjury sleep and psychosocial functioning were obtained at the initial assessment. Children completed neuropsychological testing at all occasions. Children with complicated mTBI demonstrated more total sleep problems than children with OI at 6 months postinjury, but not at 12 or 18 months. Children with sTBI displayed more bedtime resistance and shorter sleep duration than those with complicated mTBI or OI at several occasions. Across groups, total sleep problems predicted more emotional and behavioral problems and worse everyday executive function as rated by parents across follow-up occasions. In contrast, sleep problems were generally not related to neuropsychological test performance. The results suggest that young children with TBI demonstrate more sleep problems than children with injuries not involving the head. Sleep problems, in turn, significantly increase the risk of poor psychosocial outcomes across time, but are not associated with worse neuropsychological test performance.

A functional magnetic resonance imaging study of language function in international adoptees.

OBJECTIVE: To test the hypothesis that international adoption of Chinese and Eastern European girls after 9 months of age results in long-term changes in the neural circuitry supporting monolingual English in later childhood. STUDY DESIGN: Functional magnetic resonance imaging was used to test this hypothesis by comparison with a control group of American-born English speakers (n = 13). Girls now aged 6-10 years adopted from China (n = 13) and Eastern Europe (n = 12) by English-speaking families were recruited through a pediatric hospital-based international adoption center after spending more than 6 months in an orphanage or other institution, a measure of early environmental deprivation. Functional magnetic resonance imaging scans were performed on a 3 Tesla MRI scanner using a verb generation language fluency task. Composite activation maps were computed for each group using a general linear model with random effects analysis. RESULTS: Chinese born adoptees demonstrate atypical lateralization of language function with an apparent shift of temporal-parietal and frontal areas of brain activity toward the right hemisphere. Eastern European adoptees exhibited a rightward shift relative to controls in both frontal and temporal-parietal brain regions. CONCLUSIONS: Significant differences in lateralization between the Chinese and American-born groups in temporal-parietal language areas highlight the possible impact of early tonal Asian language exposure on neural circuitry. Findings suggest that exposure to an Asian language during infancy can leave a long-term imprint on the neural circuitry supporting English language development.

Age at injury and long-term behavior problems after traumatic brain injury in young children.

OBJECTIVE: This study examined the effects of age at injury on the persistence of behavior problems and social skill deficits in young children with complicated mild to severe traumatic brain injury (TBI). METHOD: A concurrent cohort/prospective research design was used with repeated assessments of children with TBI (n = 82) or Orthopedic Injury (OI) (n = 114). Parents completed the Child Behavior Checklist, the Behavior Rating Inventory of Executive Functions, and the Preschool and Kindergarten Behavior Scales or the Home and Community Social and Behavior Scales shortly after injury to assess preinjury functioning, and at an extended follow-up an average of 38 months postinjury. Generalized linear modeling was used to examine the relationship of age at injury to the maintenance of behavior problems, and logistic regression was used to examine the persistence of clinically significant behavior problems. RESULTS: At the extended follow-up, severe TBI was associated with significantly greater anxiety problems relative to the Group OI. With increasing time since injury, children who sustained a severe TBI at an earlier age had significantly higher levels of parent-reported symptoms of ADHD and anxiety than children who were older at injury. CONCLUSIONS: Findings suggest that longer-term treatment for behavior problems may be needed after severe TBI, particularly for those injured at an earlier age.

A randomized trial of teen online problem solving: efficacy in improving caregiver outcomes after brain injury.

OBJECTIVE: To examine the results of a randomized clinical trial (RCT) of Teen Online Problem Solving (TOPS), an online problem solving therapy model, in increasing problem-solving skills and decreasing depressive symptoms and global distress for caregivers of adolescents with traumatic brain injury (TBI). METHOD: Families of adolescents aged 11-18 who sustained a moderate to severe TBI between 3 and 19 months earlier were recruited from hospital trauma registries. Participants were assigned to receive a web-based, problem-solving intervention (TOPS, n = 20), or access to online resources pertaining to TBI (Internet Resource Comparison; IRC; n = 21). Parent report of problem solving skills, depressive symptoms, global distress, utilization, and satisfaction were assessed pre- and posttreatment. Groups were compared on follow-up scores after controlling for pretreatment levels. Family income was examined as a potential moderator of treatment efficacy. Improvement in problem solving was examined as a mediator of reductions in depression and distress. RESULTS: Forty-one participants provided consent and completed baseline assessments, with follow-up assessments completed on 35 participants (16 TOPS and 19 IRC). Parents in both groups reported a high level of satisfaction with both interventions. Improvements in problem solving skills and depression were moderated by family income, with caregivers of lower income in TOPS reporting greater improvements. Increases in problem solving partially mediated reductions in global distress. CONCLUSIONS: Findings suggest that TOPS may be effective in improving problem solving skills and reducing depressive symptoms for certain subsets of caregivers in families of adolescents with TBI.

Cognitive predictors of academic achievement in young children 1 year after traumatic brain injury.

OBJECTIVE: To examine cognitive predictors of academic achievement in young children with traumatic brain injury (TBI) and orthopedic injury (OI) shortly after injury and 1 year postinjury. METHODS: Participants included 3- to 6-year-old children, 63 with TBI (46 with moderate TBI and 17 with severe TBI) and a comparison group of 80 children with OI. Academic achievement was assessed approximately 1 and 12 months postinjury using three subtests from the Woodcock-Johnson Tests of Achievement-Third Edition and the School Readiness Composite from the Bracken Basic Concepts Scale-Revised. General intellectual functioning, memory, and executive functions were measured at the initial assessment using standardized tests. RESULTS: Hierarchical linear regression was used to predict academic achievement at the initial and 1-year follow-up assessments. Memory and executive functions were significant predictors of academic achievement at both assessments after controlling for group membership and demographic variables. Executive function remained a significant predictor of some outcomes after taking general intellectual functioning into account. Predictive relationships did not vary across the TBI and OI groups. Similar results were obtained when regression analyses were completed with only TBI participants using the Glasgow Coma Scale score as a predictor, although memory and executive functioning were somewhat less robust in predicting academic achievement than before. CONCLUSION: Memory and executive function predict academic achievement after TBI in preschool children, although some of the associations may be accounted for by general intellectual functioning.

Systematic review of the application of quality improvement methodologies from the manufacturing industry to surgical healthcare.

BACKGROUND: The demand for the highest-quality patient care coupled with pressure on funding has led to the increasing use of quality improvement (QI) methodologies from the manufacturing industry. The aim of this systematic review was to identify and evaluate the application and effectiveness of these QI methodologies to the field of surgery. METHODS: MEDLINE, the Cochrane Database, Allied and Complementary Medicine Database, British Nursing Index, Cumulative Index to Nursing and Allied Health Literature, Embase, Health Business(™) Elite, the Health Management Information Consortium and PsycINFO(®) were searched according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Empirical studies were included that implemented a described QI methodology to surgical care and analysed a named outcome statistically. RESULTS: Some 34 of 1595 articles identified met the inclusion criteria after consensus from two independent investigators. Nine studies described continuous quality improvement (CQI), five Six Sigma, five total quality management (TQM), five plan-do-study-act (PDSA) or plan-do-check-act (PDCA) cycles, five statistical process control (SPC) or statistical quality control (SQC), four Lean and one Lean Six Sigma; 20 of the studies were undertaken in the USA. The most common aims were to reduce complications or improve outcomes (11), to reduce infection (7), and to reduce theatre delays (7). There was one randomized controlled trial. CONCLUSION: QI methodologies from industry can have significant effects on improving surgical care, from reducing infection rates to increasing operating room efficiency. The evidence is generally of suboptimal quality, and rigorous randomized multicentre studies are needed to bring evidence-based management into the same league as evidence-based medicine.

Effect on behavior problems of teen online problem-solving for adolescent traumatic brain injury.

PURPOSE: To report the results of a randomized clinical trial of teen online problem-solving (TOPS) meant to improve behavioral outcomes of adolescents with traumatic brain injury (TBI). METHODS: A randomized clinical trial was conducted to compare the efficacy of TOPS with access to Internet resources in teenagers with TBI in improving parent and self-reported behavior problems and parent-teen conflicts. Participants included 41 adolescents aged 11 to 18 years (range: 11.47-17.90 years) who had sustained a moderate-to-severe TBI between 3 and 19 months earlier. Teens in the TOPS group received 10 to 14 online sessions that provided training in problem-solving, communication skills, and self-regulation. Outcomes were assessed before treatment and at a follow-up assessment an average of 8 months later. Groups were compared on follow-up scores after we controlled for pretreatment levels. Injury severity and socioeconomic status were examined as potential moderators of treatment efficacy. RESULTS: Forty-one participants provided consent and completed baseline assessments, and follow-up assessments were completed for 35 participants (16 TOPS, 19 Internet resource comparison). The TOPS group reported significantly less parent-teen conflict at follow-up than did the Internet-resource-comparison group. Improvements in teen behavior after TOPS were moderated by injury severity; there were greater improvements in the teens' internalizing symptoms after TOPS among adolescents with severe TBI. Family socioeconomic status also moderated the efficacy of TOPS in improving behavior problems reported by both parents and teens, although the nature of the moderation effects varied. CONCLUSION: Our findings suggest that TOPS contributes to improvements in parent-teen conflict generally and parent and self-reported teen behavior problems for certain subsets of participants.

Caregiver ratings of long-term executive dysfunction and attention problems after early childhood traumatic brain injury: family functioning is important.

OBJECTIVE: To evaluate the relationship of family and parenting factors to long-term executive dysfunction and attention problems after early childhood traumatic brain injury (TBI). We hypothesized that the magnitude of executive dysfunction and attention problems would be moderated by family and parenting factors. DESIGN: A multicenter, prospective cohort study that included an orthopedic injury (OI) reference group. SETTING: Three tertiary academic children's hospital medical centers and one general medical center. PARTICIPANTS: Children, ages 3-7 years, hospitalized for OI, moderate TBI, or severe TBI. METHODS AND OUTCOME MEASUREMENTS: Parental ratings of family functioning and parenting styles were obtained 18 months after the injury occurred. The main outcome measurements, which were parental ratings of children's executive function and attention, were performed at least 24 months after the injury occurred (mean, 39 months; range, 25-63 months). ANALYSIS: Group comparisons were conducted with use of t-tests, χ(2) analysis, analysis of variance, and Pearson and Spearman correlations. Regression analysis was used to examine associations of the outcomes with family functioning and parenting styles and to test moderating effects of these factors on group differences. RESULTS: Participants with severe TBI demonstrated increased executive dysfunction and attention problems compared with those who sustained moderate TBI or OI. Lower levels of family dysfunction were associated with better executive function and attention across groups but did not moderate group differences. However, attention deficits after severe TBI were exacerbated under conditions of more permissive parenting relative to attention deficits after OIs. CONCLUSIONS: Executive function and attention problems persisted on a long-term basis (>24 months) after early childhood TBI, and positive global family functioning and nonpermissive parenting were associated with better outcomes. Better characterization of the optimal family environment for recovery from early childhood TBI could help target future interventions.

Parenting style is related to executive dysfunction after brain injury in children.

OBJECTIVE: The goal of this study was to examine how parenting style (authoritarian, authoritative, permissive) and family functioning are related to behavioral aspects of executive function following traumatic brain injury (TBI) in young children. METHOD: Participants included 75 children with TBI and 97 children with orthopedic injuries (OI), ages 3-7 years at injury. Pre-injury parenting behavior and family functioning were assessed shortly after injury, and postinjury executive functions were assessed using the Behavior Rating Inventory of Executive Functioning (BRIEF; Gioia & Isquith, 2004) at 6, 12, and 18 months postinjury. Mixed model analyses, using pre-injury executive functioning (assessed by the BRIEF at baseline) as a covariate, examined the relationship of parenting style and family characteristics to executive functioning in children with moderate and severe TBI compared to OI. RESULTS: Among children with moderate TBI, higher levels of authoritarian parenting were associated with greater executive difficulties at 12 and 18 months following injury. Permissive and authoritative parenting styles were not significantly associated with postinjury executive skills. Finally, fewer family resources predicted more executive deficits across all of the groups, regardless of injury type. CONCLUSION: These findings provide additional evidence regarding the role of the social and familial environment in emerging behavior problems following childhood TBI.

The relationship of parental warm responsiveness and negativity to emerging behavior problems following traumatic brain injury in young children.

Parenting behaviors play a critical role in the child's behavioral development, particularly for children with neurological deficits. This study examined the relationship of parental warm responsiveness and negativity to changes in behavior following traumatic brain injury (TBI) in young children relative to an age-matched cohort of children with orthopedic injuries (OI). It was hypothesized that responsive parenting would buffer the adverse effects of TBI on child behavior, whereas parental negativity would exacerbate these effects. Children, ages 3-7 years, hospitalized for TBI (n = 80) or OI (n = 113), were seen acutely and again 6 months later. Parent-child dyads were videotaped during free play. Parents completed behavior ratings (Child Behavior Checklist; T. M. Achenbach & L. A. Rescorla, 2001) at both visits, with baseline ratings reflecting preinjury behavior. Hypotheses were tested using multiple regression, with preinjury behavior ratings, race, income, child IQ, family functioning, and acute parental distress serving as covariates. Parental responsiveness and negativity had stronger associations with emerging externalizing behaviors and attention-deficit/hyperactivity disorder symptoms among children with severe TBI. Findings suggest that parenting quality may facilitate or impede behavioral recovery following early TBI. Interventions that increase positive parenting may partially ameliorate emerging behavior problems.

A randomized trial of teen online problem solving for improving executive function deficits following pediatric traumatic brain injury.

OBJECTIVE: To examine the efficacy of teen online problem solving (TOPS) in improving executive function (EF) deficits following traumatic brain injury (TBI) in adolescence. METHODS: Families of adolescents (aged 11-18 years) with moderate to severe TBI were recruited from the trauma registry of 2 tertiary-care children's hospitals and then randomly assigned to receive TOPS (n = 20), a cognitive-behavioral, skill-building intervention, or access to online resources regarding TBI (Internet resource comparison; n = 21). Parent and teen reports of EF were assessed at baseline and a posttreatment follow-up (mean = 7.88 months later). RESULTS: Improvements in self-reported EF skills were moderated by TBI severity, with teens with severe TBI in the TOPS treatment reporting significantly greater improvements than did those with severe TBI in the Internet resource comparison. The treatment groups did not differ on parent ratings of EF at the follow up. CONCLUSIONS: Findings suggest that TOPS may be effective in improving EF skills among teens with severe TBI.

Impact of postprandial and fasting glucose concentrations on HbA1c in patients with type 2 diabetes.

AIM: This study aimed to assess the relative contributions of postprandial and fasting glucose concentrations to overall hyperglycaemia. METHODS: Patients with type 2 diabetes (n=973) carried out self-monitored blood glucose (SMBG) profiles on entry into the European Exenatide (EUREXA) trial. Glucose area under the curve was calculated for postprandial excursions (AUC(ppg)) and total daytime concentrations >6.1 mmol/L (AUC(total)), as well as for the percentage of glycaemia due to postprandial excursions (%(ppg)). In addition, OGTT scores were assessed for each patient. Results were evaluated according to defined HbA(1c) categories. RESULTS: There was a significant linear relationship between HbA(1c) and the derived variables of AUC(ppg), AUC(total) and %(ppg) (P<0.001 for each), with explained variance greatest for AUC(total) (r(2)=37.4%). AUC(ppg) increased only slightly up to an HbA(1c) of 7.0%, but showed a steeper increase in higher HbA(1c) categories. Also, the increase in AUC(total) with increasing HbA(1c) was much more pronounced. As a result, the postprandial glucose excursion as a proportion of total glucose (%(ppg)) decreased across HbA(1c) categories from 61.0% at HbA(1c)<6.5% to 22.0% at HbA(1c)≥9.0%. HOMA-IR remained virtually unchanged through all HbA(1c) categories, while HOMA-B showed no large changes up to HbA(1c) 7.0%, but then decreased at higher HbA(1c) values. The ΔI30/ΔG30 ratio decreased in the HbA(1c) 7.0-7.9% category, but did not change greatly at higher HbA(1c) categories. CONCLUSION: With increasing HbA(1c), there was a decrease in the contribution of postprandial hyperglycaemia to total glycaemia, and fasting hyperglycaemia became more important. This is consistent with impaired insulin release, particularly first-phase release, at higher HbA(1c) levels.

Caregiver functioning following early childhood TBI: do moms and dads respond differently?

INTRODUCTION: Research suggests that pediatric TBI results in injury-related stress and burden and psychological distress for parents. However, existing studies have focused almost exclusively on mothers, so that we know relatively little about the impact of childhood TBI on fathers. SPECIFIC AIMS: The aims were to prospectively examine differences in maternal and paternal response to early childhood TBI over time relative to a comparison cohort of mothers and fathers of children with orthopedic injuries (OI). METHODS: The concurrent cohort/prospective research design involved repeated assessments of children aged 3-6 years with TBI or OI requiring hospitalization and their families. Shortly after injury and at 6, 12, and 18 months post injury, parents of 48 children with TBI (11 severe and 37 moderate) and 89 with OI completed standardized assessments of injury-related stress and burden, parental distress, and coping strategies. Mixed models analyses and Generalized Estimating Equations examined differences in maternal versus paternal burden, distress, and coping over time. The analyses included interactions of parent sex with group (severe TBI, moderate TBI, OI) and time since injury, to examine the moderating effects of injury severity on parental response to injury over time. RESULTS: Fathers were more likely than mothers to use denial to cope following moderate and severe TBI, but not OI. Conversely, mothers were more likely to prefer acceptance and emotion-focused strategies than fathers regardless of the type of injury. The use of active coping strategies varied as a function of injury type, parent sex, and time since injury. Fathers reported greater injury-related stress and distress than mothers over time, with pronounced differences in the severe TBI and OI groups. CONCLUSIONS: Mothers and fathers appear to respond differently following TBI. The different types of responses may serve to exacerbate emerging family dysfunction.

Family adaptation 18 months after traumatic brain injury in early childhood.

OBJECTIVE: The purpose of this study was to examine family adaptation to a traumatic brain injury (TBI) in young children during the first 18-month postinjury, when compared with children who had an orthopedic injury. METHODS: A concurrent cohort/prospective research design was used with repeated assessments of children aged 3 to 6 years with TBI or orthopedic injury requiring hospitalization and their families. Shortly after injury and at 6-, 12-, and 18-month postinjury, parents of 99 children with TBI (20 severe, 64 moderate, 15 mild) and 117 with orthopedic injury completed standardized assessments of family functioning, parental distress and coping, injury-related burden, and noninjury-related parent stressors and resources. Mixed models analyses examined group differences in parental burden and distress adjusted for race and social demographic factors. RESULTS: Both moderate and severe TBI were associated with higher levels of injury-related stress than orthopedic injury, with stress levels diminishing over time in all groups. Severe TBI was also associated with greater psychological distress on the Brief Symptom Inventory but not with more depressive symptoms. Family functioning and social resources moderated the relationship of TBI severity to injury-related burden and caregiver distress, respectively. Lower child adaptive skills were associated with poorer family outcome but group differences remained even when controlling for this effect. CONCLUSIONS: Severe TBI in young children has adverse consequences for parents and families during the first 18-month postinjury. The consequences lessen over time for many families and vary as a function of social resources.
