Preliminary findings on TBI knowledge of professionals working with justice-involved youth.

Professionals working with justice-involved youth (JIYs) play a critical role in identifying and providing supports and services related to traumatic brain injury (TBI). The aim of this study was to better understand the knowledge of TBI of professionals working with JIYs, a research priority identified by the National Conference of State Legislatures. Fifty employees of an urban juvenile court system completed an online survey about their TBI knowledge. Respondents scored an average of 77.31% correct, yet patterns emerged in item responses and based on participant characteristics that indicate opportunities for training and education on TBI. The results of this preliminary study provide foundational evidence on TBI knowledge of professionals working with JIYs, inform future TBI-related trainings and education provided to professionals working with JIYs, and inform other practices and policies related to JIYs with TBI.

Factors impacting educational outcomes for students with traumatic brain injury in BrainSTEPS.

Purpose: To describe child pre-injury and injury factors impacting post-injury educational outcomes for students with traumatic brain injury (TBI) participating in a state-wide, school-based, school re-entry consultation program, BrainSTEPS in Pennsylvania.Method: Retrospective analysis of a BrainSTEPS annual follow-up survey.Result: A total of 296 parent surveys were completed. Analysis revealed a significant difference between levels of severity of TBI and current educational placement (p < 0.001), receipt of current therapy (p < 0.05) and need for additional consult (p < 0.05). Severity of TBI was not related to other examined educational outcome variables (i.e. school performance, current symptoms). History of TBI, symptoms and treatment were not found to be associated with educational outcomes.Conclusion: These results both support findings from previous studies, and extend previous work by highlighting ongoing needs, including continued, individualised support, of children who sustain a moderate-severe TBI during childhood, and are currently in the chronic stages of injury, with consideration of pre- and post- injury factors. Programs such as BrainSTEPS provide identification of educational needs and provide needed services and supports for children with TBI. Sensitive, validated measures are needed to further understand the role of pre-injury and injury factors on educational outcomes, particularly in programs like BrainSTEPS.

Factors that Influence Follow-Up Care for Families of Children with Acquired Brain Injury: A Scoping Review.

PURPOSE: To describe factors that contribute to medical/rehabilitation service access following pediatric acquired brain injury (ABI) and identify gaps in the literature to guide future research. MATERIALS & METHODS: The PRISMA framework for scoping reviews guided this process. Peer-reviewed journal databases were searched for articles published between 1/2008 and 12/2020, identifying 400 unique articles. For full inclusion, articles had to examine a variable related to the receipt or initiation of medical/rehabilitative services for children with ABI. Review articles and non-English articles were excluded. RESULTS: Nine studies met full inclusion criteria. Included studies identified factors focused on four primary areas: understanding brain injury education/recommendations and ease of implementing recommendations, ease of scheduling and attending appointments, age/injury factors, and sociocultural factors. Well-scheduled appointments and simple strategies facilitated families' access to care and implementation of recommendations. An overwhelming number of recommendations, socioeconomic variables, and transportation challenges served as barriers for families and schools. CONCLUSIONS: This scoping review offers several directions on which researchers can build to improve access to care and recommendation-implementation for families who have a child with an ABI. Enhanced understanding of these factors may lead to better service access, reduction of unmet needs, and enhanced long-term outcomes for children with ABI.

Gaps in concussion management across school-aged children.

OBJECTIVE: Examine how demographic and injury factors impact identification and management of concussion in students. METHODS: Prospective observational cohort. Pre-K - 12th grade students within a large, urban school district reported to school with concussion during 2015-2019. Participants were grouped into Elementary/Middle School (E/MS) and High School (HS) and compared by sex, concussion history, injury setting and mechanism, time to medical evaluation and clearance, absences, and recommended accommodations. RESULTS: 154 E/MS and 230 HS students reported to school with physician-diagnosed concussion. E/MS students experienced fewer concussions at school and from sports than HS. More E/MS males than females sustained concussions, while this difference was reversed for HS. Time-to-evaluation was longer for E/MS, specifically female E/MS students and those injured outside of school. E/MS males were cleared more quickly than females. In contrast, no differences were found between sexes for HS by injury setting, mechanism of injury, or management factors. CONCLUSION: Differences observed in E/MS students by demographic and injury factors are not observed in HS students. Younger students, particularly females or those not injured in school or sports, may be at risk for delayed identification and prolonged time to clearance. Future research should further characterize concussion management in E/MS children.

Supporting Students with TBI: A Clinically Focused Tutorial for Speech-Language Pathologists.

Attention to pediatric traumatic brain injury (TBI) has grown in recent years, likely due to the increased awareness of mild TBI (mTBI) in contact sports. With this increased attention, along with an increased diagnosis of injury, more students with TBI need services, especially as they return to the classroom environment and progress through school. Support of students with TBI of all severities requires an interdisciplinary team with the school-based speech-language pathologist playing a critical role. The purpose of this tutorial is to provide a clinically focused summary of the complexities that exist for students with TBI of all severities and practical steps that can be implemented in clinical practice to enhance service provision for students with TBI.

The Speech-Language Pathologists' Role in Mild Traumatic Brain Injury for Early Childhood-, Preschool-, and Elementary School-Age Children: Viewpoints on Guidelines From the Centers for Disease Control and Prevention.

Purpose Traumatic brain injury (TBI) impacts millions of children each year, with those between birth and 4 years of age being 1 of the highest incidence groups. To address gaps in service provision specifically for children with mild TBI (mTBI), the Centers for Disease Control and Prevention (CDC) recently released guidelines for providers. Method The goal of this commentary is to deliver viewpoints on the application of the CDC guidelines directly to speech-language pathology clinical practice, with special attention paid to assessment, symptom monitoring, and intervention using a family-centered approach to care for infants, toddlers, preschoolers, and early elementary students with mTBI. Results In all pediatric practice settings, speech-language pathologists (SLPs) are a critical component of the care team for children who experience mTBI and should participate in symptom monitoring, assessment, intervention, education, and advocacy for this population. Conclusions SLPs can use the CDC guidelines to advocate for their role in the care of young children with mTBI. In addition, SLPs can use the guidelines to create a framework for clinical care provision when working with young children with mTBI. Much work is needed to advance evidence-based practices for this population, and dissemination of current clinical practices could help to close this gap.

fMRI reveals reciprocal inhibition between social and physical cognitive domains.

Two lines of evidence indicate that there exists a reciprocal inhibitory relationship between opposed brain networks. First, most attention-demanding cognitive tasks activate a stereotypical set of brain areas, known as the task-positive network and simultaneously deactivate a different set of brain regions, commonly referred to as the task negative or default mode network. Second, functional connectivity analyses show that these same opposed networks are anti-correlated in the resting state. We hypothesize that these reciprocally inhibitory effects reflect two incompatible cognitive modes, each of which may be directed towards understanding the external world. Thus, engaging one mode activates one set of regions and suppresses activity in the other. We test this hypothesis by identifying two types of problem-solving task which, on the basis of prior work, have been consistently associated with the task positive and task negative regions: tasks requiring social cognition, i.e., reasoning about the mental states of other persons, and tasks requiring physical cognition, i.e., reasoning about the causal/mechanical properties of inanimate objects. Social and mechanical reasoning tasks were presented to neurologically normal participants during fMRI. Each task type was presented using both text and video clips. Regardless of presentation modality, we observed clear evidence of reciprocal suppression: social tasks deactivated regions associated with mechanical reasoning and mechanical tasks deactivated regions associated with social reasoning. These findings are not explained by self-referential processes, task engagement, mental simulation, mental time travel or external vs. internal attention, all factors previously hypothesized to explain default mode network activity. Analyses of resting state data revealed a close match between the regions our tasks identified as reciprocally inhibitory and regions of maximal anti-correlation in the resting state. These results indicate the reciprocal inhibition is not attributable to constraints inherent in the tasks, but is neural in origin. Hence, there is a physiological constraint on our ability to simultaneously engage two distinct cognitive modes. Further work is needed to more precisely characterize these opposing cognitive domains.

The relation of lung volume initiation to selected acoustic properties of speech.

This study examined the relationship of speech breathing to other elements of speech production. It was hypothesized that initiating speech from different lung volumes would have an effect on different elements of the acoustic output. It was postulated that effects may be brought about by mechanical interaction as well as a dispersion of effort to mechanically unlinked elements of speech production, such as articulatory behavior. To this end, selected acoustic variables were studied in eight young healthy women who initiated speech from low, typical, and high lung volume levels. The acoustic variables studied were selected because they have been shown to be sensitive indicators of speech production performance. It was found that with increasing lung volume initiation levels, average sound pressure level, average fundamental frequency, and declination rate of fundamental frequency increased. It was also observed that vowel space was significantly smaller during low lung volume initiation levels relative to typical lung volume initiation levels. Vowel space reduction is discussed relative to "gaining down."
