The Behavior Rating Inventory of Executive Function (BRIEF) to Identify Pediatric Acute Lymphoblastic Leukemia (ALL) Survivors At Risk for Neurocognitive Impairment

Fatigue, Fogginess, and Sleep Complaints: Presence and Impact on Functioning After Childhood Traumatic Brain Injury

PURPOSE

The purpose of this study was to examine the occurrence and impact of fatigue, fogginess, and sleep complaints on functioning at 3, 6, 10, and 16 months after childhood traumatic brain injury (TBI).

METHOD

Eighty-eight caregivers completed online surveys regarding their children with TBI, with 17 participants included at the final time point. Measures included questions related to demographic and injury characteristics, executive functioning, social relations, health-related quality of life, and fatigue, fogginess, and sleep complaints.

RESULTS

Fatigue, fogginess, and sleep complaints were persistent and ultimately increased at 16 months postinjury. Over half of the participants were experiencing each symptom at 16 months postinjury (i.e., 52.94% fatigue and fogginess, 58.82% sleep complaints). At 16 months postinjury, fatigue was significantly associated with female sex, and fatigue and sleep complaints were significantly associated with lower physical quality of life, but no other differences were found with symptoms and current functioning.

CONCLUSIONS

The results of this study support that fatigue, fogginess, and sleep complaints can persist (from baseline, from postinjury, and in fluctuation) chronically for about half of the children with TBI but little association or impact on other domains of functioning. The present study supports the continued investigation of fatigue, fogginess, and sleep complaints after childhood brain injury, but further investigation with a larger sample size is necessary to inform clinical practices for assessment and management, particularly for speech-language pathologists in rehabilitation and educational settings.

Cross-cultural adaptation, reliability, and validity of the Turkish Pediatric Quality of Life Inventory-Cognitive Functioning Scale (PedsQLTM-CFS) in children with cancer

The Pediatric Quality of Life Inventory-Cognitive Functioning Scale (PedsQLTM-CFS) was developed as a brief, general, symptom-specific tool to measure cognitive function. The 6-item PedsQL™ Cognitive Functioning Scale and PedsQL 3.0 Cancer Module answered 369 parents and 330 children with 5-18 years. Parents also completed Behavior Rating Inventory of Executive Function (BRIEF). The PedsQL™ Cognitive Functioning Scale evidenced excellent reliability (parent proxy-report α = 0.980/Fleiss Kappa: 0.794; children self-report α = 0.963/Fleiss Kappa: 0.790). Both child self-report and parent proxy-report PedsQL™ Cognitive Functioning Scale scores exhibited significant correlations with all parent-report BRIEF summary and subscale scores (p < .05). Both child self-report and parent proxy-report PedsQL™ Cognitive Functioning Scale scores exhibited significant correlations with PedsQL 3.0 Cancer Module total score and subscale scores (p < .05). The PedsQLTM-CFS can be used in high-risk populations with substantial to perfect reliability, both in regards to total/subcategory scores as well as in children with cancer.

Fatigue, Executive Functioning, and Quality of Life: Exploring Relationships in Children With Traumatic Brain Injury

PURPOSE

The overall purpose of this study was to explore the relationship between fatigue, executive functioning, and quality of life for children with moderate-severe traumatic brain injury (TBI) between 8 and 17 years old.

METHOD

Fifteen parents of children with moderate-severe TBI (M = 10.06 years old) completed an online survey. Data from the following measures were included in this study's analyses: demographic and injury questions, the Behavior Rating Inventory of Executive Function, Second Edition (BRIEF-2), Pediatric Quality of Life Inventory Generic Core Scale (PedsQL GCS)-parent report, and Pediatric Quality of Life Inventory Multidimensional Fatigue Scale (PedsQL MFS)-parent report.

RESULTS

In a multiple regression, fatigue was found to be a significant predictor of quality of life for children with TBI, but executive functioning was not a significant predictor. When examining subdomains of functioning, worse sleep/rest fatigue and emotional executive functioning were most consistently associated with worse physical and psychosocial quality of life.

CONCLUSIONS

The findings of this study suggest that fatigue could be an important contributing factor to reduced quality of life for children with moderate-severe TBI. Medical and educational professionals, including speech-language pathologists, should assess children with TBI for the presence and impact of fatigue. Further research is needed to understand how different subdomains of fatigue might interact with executive functioning to impact quality of life.

Parent ratings of executive functioning in pediatric survivors of medulloblastoma and pilocytic astrocytoma

The present study compared parent-rated executive functioning in pediatric medulloblastoma (MB) and pilocytic astrocytoma (PA) survivors. Although standard care for both includes surgical resection, children with MB additionally receive chemotherapy and craniospinal irradiation. Given well-documented neurocognitive late effects associated with the latter, we anticipated poor parent-reported executive functioning in MB survivors. Parents/guardians of 36 MB survivors and 20 PA survivors completed the Behavior Rating Inventory of Executive Functioning (BRIEF). PA survivors were younger at diagnosis (t[51.97] = 3.07, p < .001, d = 0.86) and demonstrated higher IQ (t[54] = -3.51, p < .001, d = 0.95). However, relative to the MB group, the PA group was rated as having significantly more problems on all BRIEF scales (all p ≤ .05; d = 0.30 - 1.10), except the Shift scale. Additionally, all mean BRIEF scores for MB survivors were within normal limits, whereas for PA survivors, all mean BRIEF scores except for Organization of Materials were significantly discrepant from normative means. Overall, PA survivors were rated as demonstrating poorer executive function than MB survivors. Five theories are discussed as possible explanations for these surprising findings: two related to group differences, two related to potential sources of parental bias, and one related to the nature of questionnaire-based assessment. All these theories represent directions for future research. Parent questionnaires such as the BRIEF may have real-world implications for pediatric brain tumor survivors. Future research should explore factors affecting parent ratings of executive functioning in these populations, along with comparison to performance-based measures.

Neurocognitive Outcomes in Multiethnic Pediatric Brain Tumor Patients Treated With Proton Versus Photon Radiation

BACKGROUND

We analyzed post-radiation (RT) neurocognitive outcomes in an ethnically diverse pediatric brain tumor population undergoing photon radiotherapy (XRT) and proton radiotherapy (PRT).

PROCEDURE

Post-RT neurocognitive outcomes from 49 pediatric patients (37% Hispanic/Latino) with primary brain tumors were analyzed. Tests included cognitive outcomes, behavioral outcomes, and overall intelligence. For each outcome, proportion of patients with cognitive impairment (scores <1.5 SD) was calculated. The Fisher exact tests compared proportion of patients with impairment and t tests compared T-scores between XRT (n=32) and PRT (n=17) groups. Linear regression assessed associations between radiation modality and outcomes.

RESULTS

Median follow-up was 3.2 and 1.8 years in the XRT and PRT groups, respectively. The median RT dose was 54.0 Gy. We found impairment in 16% to 42% of patients across most neurocognitive domains except executive function. There was no difference in scores between XRT and PRT groups. Regression analyses revealed no association of neurocognitive outcomes with radiation modality. Non-Hispanic patients had better Verbal Comprehension Index and General Ability Index scores than Hispanic patients ( P <0.05).

CONCLUSIONS

Among pediatric patients with brain tumors receiving RT, all cognitive domains were affected except executive function. Radiation modality was not associated with neurocognitive outcomes. Hispanic patients may be more vulnerable to posttreatment cognitive effects that warrant further study.

Exploring the Caregiver-Reported Impact of the COVID-19 Pandemic on Children with Traumatic Brain Injury

The COVID-19 pandemic is expected to have a persistent, negative, and disproportionate impact on children with disabilities. Children with traumatic brain injury (TBI) may be expected to experience a disproportionate impact given the deficits often associated with childhood TBI (e.g., family functioning, fatigue, executive functioning, quality of life). This study aimed to explore the impact of the COVID-19 pandemic on children with TBI and their families, compared to typically developing (TD) children and their families. Thirty caregivers (TBI = 15; TD = 15) completed a series of electronic survey measures. Overall, caregivers reported no negative impact of the COVID-19 pandemic on their family's or child's functioning and association with demographic factors and domains of functioning showed no clear patterns. The findings of this exploratory study support continued longitudinal investigation with larger sample sizes of the provision of supports for all families and children in light of the COVID-19 pandemic. Additional research is needed to understand the effectiveness of targeted services for students with TBI in domains of functioning that are significantly poorer than TD children (e.g., quality of life, executive functioning, fatigue).

Cognitive, social, and health functioning of children with TBI engaged in a formal support program

BACKGROUND

Students with traumatic brain injury (TBI) often demonstrate difficulties that impact their successful return to school (RTS).

OBJECTIVE

To explore injury severity, age at injury, and time since injury as predictors for performance on measures of cognitive, social and health functioning for students' participating in a formal RTS cohort at the time of their enrollment in the School Transition After Traumatic Brain Injury (STATBI) research project.

METHODS

Outcome measures across cognitive, social, and health domains were analyzed for association with the explanatory variables of interest using quantile regressions and ordinary least squares regression, as appropriate.

RESULTS

Students (N = 91) injured after age 13 showed significantly lower cognitive outcomes than students whose injury occurred earlier. Additionally, students more than one-year post-injury demonstrated poorer social outcome on one measure compared to students whose injury occurred more recently. Health outcomes showed no significant association to any predictors.

CONCLUSION

The results of this analysis provide a baseline for a group of students with TBI as they enter a RTS research study. This data can now be paired with longitudinal measures and qualitative data collected simultaneously to gain a deeper understanding of how students with TBI present for RTS.

Neuropathic pain and neurocognitive functioning in children treated for acute lymphoblastic leukemia

ABSTRACT

Children with acute lymphoblastic leukemia (ALL) often experience treatment-related neurocognitive deficits and significant pain. Pain may exacerbate these cognitive impairments. This study examined neuropathic pain and neurocognitive outcomes in survivors of childhood ALL treated with contemporary therapy on a clinical trial (NCT00137111). There were 345 survivors (45% female, M = 6.9 years at diagnosis) who completed neurocognitive assessments including measures of sustained attention, learning and memory, and parent ratings of attention during at least one of 4 time points: on-therapy (Induction and Reinduction), end of therapy, and 2 years post-therapy. At-risk performance was defined as a score at least 1SD below the age-adjusted mean. Data on neuropathic pain (events, duration, and severity according NCI Common Toxicity Criteria) and pharmacologic pain management (opioids and gabapentin) were ascertained. Results showed that 135 survivors (39%) experienced neuropathic pain during treatment. Compared with those without pain, survivors with pain had greater memory impairments at end of therapy (California Verbal Learning Test [CVLT]-Total, 24% vs 12%, P = 0.046). Within the pain group, survivors who experienced a greater number of pain events (CVLT-Total = -0.88, P = 0.023) and those who were treated with opioids (versus gabapentin) had poorer learning and memory performance (CVLT-Total = -0.73, P = 0.011; Short Delay = -0.57, P = 0.024; Long Delay = -0.62, P = 0.012; and Learning Slope = -0.45, P = 0.042) across time points. These are considered medium-to-large effects (SD = 0.45-0.88). Neuropathic pain may be a risk factor for learning problems after therapy completion, and treatment for pain with opioids may also adversely affect neurocognitive performance. Therefore, patients who experience pain may require closer monitoring and additional intervention for neurocognitive impairment.

Longitudinal Trajectories of Neurocognitive Functioning in Childhood Acute Lymphoblastic Leukemia

OBJECTIVE

Children with acute lymphoblastic leukemia (ALL) are at risk for neurocognitive deficits, and examining individual variability is essential to understand these risks. This study evaluated latent longitudinal trajectories and risk factors of neurocognitive outcomes in childhood ALL.

METHODS

There were 233 participants with ALL who were enrolled on a phase 3, risk-stratified chemotherapy-only clinical trial (NCT00137111) and who completed protocol-directed neurocognitive assessments [47.6% female, mean (SD) = 6.6 (3.7) years]. Measures of sustained attention, learning/memory, and parent ratings of attention were completed during and after treatment. Longitudinal latent class analyses were used to classify participants into distinct trajectories. Logistic regression was used to identify predictors of class membership.

RESULTS

Within the overall group, attention performance was below age expectations across time (Conners Continuous Performance Test detectability/variability, p < 0.01); memory performance and parent ratings were below expectations at later phases (California Verbal Learning Test learning slope, p < 0.05; Conners Parent Rating Scale, Revised attention/learning, p < 0.05). Most participants (80-89%) had stable neurocognitive profiles; smaller groups showed declining (3-6%) or improving (3-11%) trajectories. Older age (p = 0.020), female sex (p = 0.018), and experiencing sepsis (p = 0.047) were associated with greater attention problems over time. Lower baseline IQ was associated with improved memory (p = 0.035) and fewer ratings of attention problems (p = 0.013) over time.

CONCLUSIONS

Most patients with ALL have stable neurocognitive profiles. Smaller groups have significant impairments shortly after diagnosis or have worsening performance over time. A tiered assessment approach, which includes consideration of individual and clinical risk factors, may be useful for monitoring neurocognitive functioning during treatment and survivorship.

Anatomical brain MRI study of pediatric cancer survivors treated with chemotherapy: Correlation with behavioral measures

The negative impacts of chemotherapy on pediatric patients treated with chemotherapy during the formative years of brain development are understudied compared to adult chemotherapy cancer patients. This work investigated the morphometry, cortical thickness, and subcortical volumes using MRI and their correlations with behavioral measures in pediatric oncology survivors treated with chemotherapy. Chemotherapy-treated childhood cancer survivors (N = 15, 15.12 ± 5.98 years old) diagnosed with a non-central nervous system malignancy and healthy age-matched controls (N = 15, 15.13 ± 4.21 years old) were studied. MRI was acquired at 3 Tesla. Behavioral Rating Inventory of Executive Functioning (BRIEF) Parental Rating, Purdue Pegboard manual dexterity and n-back working memory measures were administered. Structural MRI scans at 3 Tesla were acquired. Voxel-based morphometry, cortical thickness and subcortical volumes were analyzed and correlated with behavioral scores. Parametric statistics with a p < .05 and adjusted for multiple comparison corrections were performed. Patients exhibited significantly smaller gray-matter volumes in the left globus pallidum, bilateral thalami, left caudate and left nucleus accumbens (p < .05) and thinner cortex in the right parahippocampal gyrus (p < .05) compared to controls. BRIEF scores were similar to normative values. Purdue Pegboard revealed manual dexterity deficits compared to normative values, and the n-back task showed working-memory deficits in patients compared to controls. Left thalamus volume positively correlated with dexterity performance (p = .029). The number of correct answers positively correlated and the number of incorrect answers negatively correlated with total-brain and white-matter volume (p < .05), but not gray-matter volume (p > .05). Our results support the hypothesis that the neurotoxicity of systemic chemotherapy has widespread negative effects on brain development in pediatric oncology patients with relatively mild cognitive deficits. MRI identified neuroanatomical changes have the potential to provide neural correlates of the sequelae associated with pediatric chemotherapy.

Impact of Intrathecal Triple Therapy Versus Intrathecal Methotrexate on Disease-Free Survival for High-Risk B-Lymphoblastic Leukemia: Children's Oncology Group Study AALL1131

PURPOSE

The high-risk stratum of Children's Oncology Group Study AALL1131 was designed to test the hypothesis that postinduction CNS prophylaxis with intrathecal triple therapy (ITT) including methotrexate, hydrocortisone, and cytarabine would improve the postinduction 5-year disease-free survival (DFS) compared with intrathecal methotrexate (IT MTX), when given on a modified augmented Berlin-Frankfurt-Münster backbone.

PATIENTS AND METHODS

Children with newly diagnosed National Cancer Institute (NCI) high-risk B-cell acute lymphoblastic leukemia (HR B-ALL) or NCI standard-risk B-ALL with defined minimal residual disease thresholds during induction were randomly assigned to receive postinduction IT MTX or ITT. Patients with CNS3-status disease were not eligible. Postinduction IT therapy was given for a total of 21 to 26 doses. Neurocognitive assessments were performed during therapy and during 1 year off therapy.

RESULTS

Random assignment was closed to accrual in March 2018 after a futility boundary had been crossed, concluding that ITT could not be shown to be superior to IT MTX. The 5-year postinduction DFS and overall survival rates (± SE) of children randomly assigned to IT MTX versus ITT were 93.2% ± 2.1% v 90.6% ± 2.3% (P = .85), and 96.3% ± 1.5% v 96.7% ± 1.4% (P = .77), respectively. There were no differences in the cumulative incidence of isolated bone marrow relapse, isolated CNS relapse, or combined bone marrow and CNS relapse rates, or in toxicities observed for patients receiving IT MTX compared with ITT. There were no significant differences in neurocognitive outcomes for patients receiving IT MTX compared with ITT.

CONCLUSION

Postinduction CNS prophylaxis with ITT did not improve 5-year DFS for children with HR B-ALL. The standard of care for CNS prophylaxis for children with B-ALL and no overt CNS involvement remains IT MTX.

Monitoring neurocognitive functioning in childhood cancer survivors: evaluation of CogState computerized assessment and the Behavior Rating Inventory of Executive Function (BRIEF)

BACKGROUND

Many childhood cancer survivors develop neurocognitive impairment, negatively affecting education and psychosocial functioning. Recommended comprehensive neuropsychological testing can be time- and cost- intensive for both institutions and patients and their families. It is important to find quick and easily administered surveillance measures to identify those in need of evaluation.

METHODS

We evaluated, individually and in combination, the sensitivity and specificity of the 1) Behavior Rating Inventory of Executive Functioning-Metacognition Index (BRIEF-MCI), and 2) CogState Composite Index (computerized assessment of cognition) in identifying below grade-level performance on state-administered tests of reading and mathematics among childhood cancer survivors.

RESULTS

The 45 participants (39% female) were a mean age of 7.1 ± 4.4 years at diagnosis, 14.0 ± 3.0 at evaluation, with a history of leukemia (58%), lymphoma (9%), central nervous system tumors (20%), and other tumors (13%). Impairment on the BRIEF-MCI was associated with low sensitivity (26% reading, 41% mathematics) but stronger specificity (88% reading, 96% mathematics). We found similar associations for the CogState Composite Index with sensitivity of 26% for reading and 29% for mathematics and specificity of 92% for both reading and mathematics. Combining the two measures did not improve sensitivity appreciably (47% reading, 59% mathematics) while reducing specificity (84% reading, 88% mathematics).

CONCLUSIONS

While individuals identified from the BRIEF-MCI or CogState Composite would likely benefit from a full neuropsychological evaluation given the strong specificity, use of these measures as screening tools is limited. With poor sensitivity, they do not identify many patients with academic difficulties and in need of a full neuropsychological evaluation. Continued effort is required to find screening measures that have both strong sensitivity and specificity.
