ABSTRACT

Protective factors, including psychological resilience, cognitive reserve, and brain reserve, may be positively associated with recovery after pediatric mild traumatic brain injury (mTBI) but have yet to be studied concurrently. We sought to examine these factors as moderators of post-concussive symptoms (PCS) in pediatric mTBI compared to mild orthopedic injury (OI). Participants included 967 children (633 mTBI, 334 OI) aged 8-16.99 years, recruited from 5 Canadian pediatric emergency departments as part of a prospective longitudinal cohort study. At 10 days post-injury, psychological resilience was measured using the Connor-Davidson Resilience Scale (CD-RISC) and brain reserve was measured using total brain volume (TBV) derived from structural magnetic resonance imaging . Cognitive reserve was measured at 3 months post-injury using IQ scores from the Wechsler Abbreviated Scale of Intelligence-Second Edition. Cognitive and somatic PCS were measured using child and parent ratings on the Health and Behavior Inventory, completed weekly for 3 months and bi-weekly to 6 months. Analyses involved generalized least squares regression models using restricted cubic splines. Covariates included age at injury, sex, racialized identity, material and social deprivation, pre-injury migraine and concussion history, and retrospective pre-injury PCS. Psychological resilience moderated group differences in parent-reported PCS. At 30 days post-injury, estimated group differences in parent-reported cognitive and somatic PCS (mTBI > OI) were larger at higher (75th percentile) resilience scores (Est = 2.25 [0.87, 3.64] and Est = 2.38 [1.76, 3.00], respectively) than at lower (25th percentile) resilience scores (Est = 1.44 [0.01, 2.86] and Est = 2.08 [1.45, 2.71], respectively). Resilience did not moderate group differences in child-reported PCS but was negatively associated with child-reported PCS in both groups (ps < .001). Brain reserve (i.e., TBV) also moderated group differences, but only for parent-reported somatic PCS (p = .018). Group difference (mTBI > OI) at 30 days were larger at smaller (25th percentile) TBV (Est = 2.78 [2.17, 3.38]) than at larger (75th percentile) TBV (Est = 1.95 [1.31, 2.59]). TBV was not associated with parent-reported cognitive PCS or child-reported PCS. IQ did not moderate PCS in either group but had a significant non-linear association in both groups with child-reported somatic PCS (p = .018) and parent-reported PCS (p < .001), with higher PCS scores at both lower and higher IQs. These findings suggest that higher resilience predicts fewer PCS, but less strongly after mTBI than OI; greater brain reserve may reduce the effect of mTBI on somatic PCS; and cognitive reserve has an unexpected curvilinear association with PCS across injury types. The results highlight the importance of protective factors as predictors of recovery and potential targets for intervention following pediatric mTBI.

ABSTRACT

BACKGROUND: The number of pediatric SOT recipients surviving into adulthood is increasing. Thus, understanding their psychosocial and QoL outcomes is important. We conducted a systematic review to collate existing literature examining QoL outcomes (physical functioning, psychological functioning, social functioning), as well as risk and protective factors associated with QoL, among adults who underwent SOT during childhood. METHODS: A systematic search of five databases, from inception to January 6, 2021, was conducted to identify articles that reported on QoL outcomes for adults (≥18-year of age) who received a SOT during childhood (<19-year of age). RESULTS: Twenty-five articles met inclusion criteria. Studies examined QoL across a range of SOT populations (liver, kidney, heart). QoL and psychosocial outcomes were variable; however, the majority of studies indicated QoL in this population to be similar to the general population, or at least similar to other chronic illness groups, with the exception of physical and social functioning. Factors related to a more optimal medical course, younger age at transplant and follow-up, and positive psychosocial functioning, were found to be predictive of better QoL outcomes. CONCLUSIONS: While several studies indicated QoL to be similar to the general population, the literature is limited in both quantity and quality. No study employed prospective, longitudinal methodologies to systematically evaluate QoL over time and few studies utilized normative-based measures of QoL. Furthermore, several SOT groups were under-represented in the literature (e.g., lung, intestine, multi-visceral). Nonetheless, findings have implications for intervention and clinical decision-making.

ABSTRACT

Objective. The current study examined the effects of clinical factors (i.e., treatment type, history of cerebellar mutism) as well as environmental factors (i.e., family environment) as predictors of cognitive and psychosocial outcomes in children treated for posterior fossa tumors.Method. Twenty-seven children/adolescents treated for posterior fossa tumors (treatment type: radiation [n = 12], surgery [n = 15]; history of mutism: yes [n = 7], no [n = 20]) and n = 13 healthy controls, aged 8-17 years, and their caregivers completed measures assessing cognitive and psychosocial functioning, as well as the family environment (i.e., parental education, family functioning, family psychiatric history). Hierarchical linear regression analyses were conducted to examine the role of clinical factors and the family environment as predictors of cognitive and psychosocial outcomes. Family environment was also examined as a moderator of clinical factor group differences in outcomes.Results. Regression analyses revealed lower intelligence scores among the radiation group compared to the control group, lower verbal memory scores among both treatment groups compared to the control group, and a significant positive effect of parental education on verbal memory scores. Further, history of cerebellar mutism predicted poorer performance on a speeded naming task, and this relationship was moderated by family functioning, with a greater effect of mutism present among those with poorer family functioning.Conclusions. Interventions aimed at improving the family environment may help to mitigate negative cognitive effects of pediatric brain tumors, particularly among those most at-risk for poor outcomes.

ABSTRACT

OBJECTIVES: To evaluate the relationship of psychological resilience to persistent post-concussive symptoms (PCS) in children with a history of single or multiple concussions, as well as orthopedic injury (OI). METHODS: Participants (N=75) were children, ages 8-18 years, who sustained a single concussion (n=24), multiple concussions (n=25), or an OI (n=26), recruited from a tertiary care children's hospital. All participants sustained injuries at least 6 months before recruitment, with an average time since injury of 32.9 months. Self-reported psychological resilience was measured using the Connor-Davidson Resilience Scale, and both self- and parent-reported PCS were measured using the Post-Concussion Symptom Inventory. Hierarchical regression analyses examined psychological resilience as a predictor of PCS, both as a main effect and as a moderator of group differences. RESULTS: Multiple concussions and low psychological resilience were both significant predictors of persistent PCS. Resilience was not a significant moderator of group differences in PCS. CONCLUSIONS: Sustaining multiple concussions may increase a child's risk of persistent PCS; however, high psychological resilience may serve as a protective factor, regardless of the number or type of injuries sustained. These findings provide support for developing and testing interventions aimed at increasing psychological resilience as a potential means of improving outcomes for children suffering from persistent PCS after concussion.

ABSTRACT

OBJECTIVE: Psychological resilience is an important predictor of outcome in concussion; however, there is no published evidence of psychometric support for use of a measure of psychological resilience in children with concussion. This study examined construct validity of the Connor-Davidson Resilience Scale (CD-RISC) in a paediatric concussion and orthopaedic injury sample. METHODS: Seventy-five children with a history of concussion or orthopaedic injury were recruited from a children's hospital. Total sample and within-group correlations between the CD-RISC (25- and 10-item versions) and measures presumed to be related or unrelated to the construct of psychological resilience were analysed. RESULTS: In the total sample, both versions of the CD-RISC were negatively correlated with self-reported depressive symptoms and general behaviour problems. The 10-item version was also negatively correlated with parent-reported general behaviour problems and self-reported anxiety, and was positively correlated with self-reported quality of life. The injury groups did not exhibit significantly different correlations. CONCLUSIONS: The construct validity of the CD-RISC is satisfactory when used with children with concussion. The 10-item version may provide a more efficient measure of resiliency with better construct validity in this population.

ABSTRACT

OBJECTIVE: This scoping review aimed to summarize the existing knowledge base regarding depression and depressive symptoms in pediatric traumatic brain injury (TBI) and to identify gaps in the literature in an effort to guide future research. METHODS: MEDLINE Ovid and PsycINFO Ovid databases were each searched by the authors using search terms intended to identify any original research study that examined depressive symptoms in children (ie, aged 0-18 years) with TBI. RESULTS: A total of 14 published studies were included in the review. The studies included examined the prevalence of depression, risk factors associated with depression, and depression as a predictor of other TBI-related outcomes. CONCLUSION: Existing research suggests that depressive symptoms are more common in a TBI population than in a healthy or orthopedically injured population. Injury-related factors such as lesions in the brain and the presence of pain, as well as noninjury factors such as older age at injury and low socioeconomic status, may be predictive of depressive symptoms. Depression is likely a secondary outcome of pediatric TBI rather than a direct result of the injury itself. Overall, a relative dearth of research exists on this topic; thus, the review concludes by proposing future research directions.
