Multicenter studies across experimental modalities (domains) can help accelerate translation. The Translational Outcomes Project in NeuroTrauma (TOP-NT) is a pre-clinical traumatic brain injury (TBI) consortium charged with establishing and validating noninvasive TBI assessment tools through team science. Here, we present practical approaches for harmonization of TBI research across five centers providing needed vocabulary and structure to achieve centralized data organization and use. This includes data sharing as an essential step that enables validating data between domains, evaluating reproducibility between sites, and performing multimodal analyses. As part of this process, TOP-NT (1) produced a library of TBI-relevant standard operating procedures to coordinate workflow, (2) aligned 481 pre-clinical and clinical common data elements (CDEs), and (3) generated 272 new pre-clinical TBI CDEs. This consortium then (4) connected diverse data types to validate assessments across domains and to allow multivariable TBI phenotyping. Lastly, TOP-NT (5) specified technical quality controls for pre-clinical studies. These harmonization tools can facilitate reproducibility in team science, help distinguish a wide injury spectrum from technical variability, apply quality-controls, and ease higher level data analyses. TOP-NT uses three rat TBI models across four sites. Each site collects primary outcome measures, including magnetic resonance imaging (MRI) protocols and blood biomarkers of neuronal and glial injury, validated by histopathology and behavioral outcomes. Collected data are organized using the 481 TOP-NT pre-clinical CDEs, covering surgical, behavioral, biomarker, MRI, and quantitative histopathological methods. We report data curation steps suited for data storage using the Open Data Commons for TBI as a centralized data repository, allowing unbiased cross-site analysis. This approach leads to introducing a higher level, syndromic understanding of TBI signatures. TOP-NT authors outline a semantic and structural framework suggesting strategies for robust pre-clinical research in multicenter trials to improve translatability for TBI assessments.

PTE also affects driving capacity, which impacts functional independence, community participation, and satisfaction with life (SWL). However, studies evaluating the collective impact of PTE on multidimensional outcomes are lacking. Thus, we generated a model to investigate how PTE after moderate-to-severe (ms)TBI affects TBI-associated impairments, limits activities and participation, and influences SWL. Of 5108 participants with msTBI enrolled into the National Institute for Disability, Independent Living, and Rehabilitation Research TBI Model Systems between 2010 and 2018 and with seizure-event data available at year-1 post-TBI, 1214 had complete outcome data and 1003 had complete covariate data used for analysis. We constructed a conceptual framework illustrating hypothesized interrelationships between year-1 PTE, driving status, functional independence measure (FIM), depression and anxiety, as well as year-2 participation, and SWL. We performed univariate and multivariable linear and logistic regressions. A covariate-adjusted structural equation model (SEM), using the lavaan package (R), assessed the conceptual framework's suitability in establishing PTE links with outcomes 1-2 years post-injury. Multiple parameters were evaluated to assess SEM fit. Year-1 PTE was correlated with year-1 FIM motor (standardized coefficient, β&lt;sub&gt;std&lt;/sub&gt; = -0.112, &lt;i&gt;p&lt;/i&gt; = 0.007) and showed a trend level association with year-1 FIM cognition (β&lt;sub&gt;std&lt;/sub&gt; = -0.070, &lt;i&gt;p&lt;/i&gt; = 0.079). Individuals with year-1 PTE were less likely to drive independently at year 1 (β&lt;sub&gt;std&lt;/sub&gt; = -0.148, &lt;i&gt;p&lt;/i&gt; &lt; 0.001). In addition, FIM motor (β&lt;sub&gt;std&lt;/sub&gt; = 0.323, &lt;i&gt;p&lt;/i&gt; &lt; 0.001), FIM cognition (β&lt;sub&gt;std&lt;/sub&gt; = 0.181, &lt;i&gt;p&lt;/i&gt; = 0.012), and anxiety (β&lt;sub&gt;std&lt;/sub&gt; = -0.135, &lt;i&gt;p&lt;/i&gt; = 0.024) influenced driving status. FIM cognition was associated with year-1 depression (β&lt;sub&gt;std&lt;/sub&gt; = 0.386, &lt;i&gt;p&lt;/i&gt; &lt; 0.001) and year-1 anxiety (β&lt;sub&gt;std&lt;/sub&gt; = 0.396, &lt;i&gt;p&lt;/i&gt; &lt; 0.001), whereas year-1 FIM motor (β&lt;sub&gt;std&lt;/sub&gt; = 0.186, &lt;i&gt;p&lt;/i&gt; = 0.003), depression (β&lt;sub&gt;std&lt;/sub&gt; = -0.322, &lt;i&gt;p&lt;/i&gt; = 0.011), and driving status (β&lt;sub&gt;std&lt;/sub&gt; = 0.233, &lt;i&gt;p&lt;/i&gt; &lt; 0.001) directly affected year-2 objective life participation metrics.

While most of these patients do not develop critical neurological injuries, identifying those at risk would allow for a more optimal determination of the appropriate level of initial emergency care. The Brain Injury Guidelines (BIG) were developed as a triage tool to identify adult patients with mTBI and ICI who can benefit from repeat imaging, hospital admission, or neurosurgical consultation. Here, we sought to validate BIG in children at a Level I trauma center and determine if the BIG algorithm can accurately identify which patients with mTBI/ICI have critical neurosurgical injuries. We hypothesize that the BIG can identify critical neurological injuries more accurately than the Glasgow Coma Scale (GCS) alone and that more severe injury according to BIG is associated with worse patient outcome. We retrospectively reviewed TBI admissions at a single center (2017-2023) using an institutional registry. Patients included (0-17 years) had an initial head computerized tomography scan with ICI and a GCS of 14-15. Patients were retrospectively classified into the BIG categories (BIG 1, 2, or 3). Medical records were reviewed to identify clinically important TBI (ciTBI): death, neurological deterioration, neurosurgical intervention, intubation >24 h, or hospital admission >48 h due to TBI. Repeat imaging studies obtained were evaluated for progression of injury. The incidence of clinically important TBI (ciTBI) and imaging progression were recorded and compared across BIG categories. Outcomes were evaluated using the Glasgow Outcome Score Extended (GOS-E) 6 months after injury. Univariable and chi-square tests were used to analyze comparisons. Overall, 804 subjects were included in the analysis of which 551 (68.5%) were transfers. Overall, 175 (21.8%) patients had a BIG 1, 402 (50.0%) a BIG 2, and 227 (28.2%) a BIG 3 injury.

Amongst 471 patients (58.6%) with available 6-month patient outcomes, 98% had a GOS-E ≥5 and no outcome difference between BIG categories was observed. Risk stratification of mild TBI using BIG allowed for reasonable identification of children who subsequently develop ciTBI, suggesting that BIG classification can aid in triage and management of patients who might benefit from neurosurgical consultation, repeat imaging, and potentially transfer to a dedicated trauma center.

Intravenous (IV) immunomodulatory nanoparticle (IMP) administration after TBI limits inflammatory cell infiltration and reduces both behavioral decline and lesion size without any noticeable toxicity. Here we show that there is a dose-response relationship between the amount of IMP administered and tissue damage which plateaus at a well-tolerated dose. There is a therapeutic window of efficacy for IMP administration of at least 6 h after injury with some benefit observed when treatment was delayed for 12 h after injury. Single cell RNA sequencing demonstrated substantial changes in gene expression after TBI in both neural and non-neural cells in the brain, and IMP administration ameliorated many of the changes. Particularly notable were significant unexpected changes in CCR1, CXCR2, and BDNF expression in vascular smooth muscle cells that may participate in injury responses after TBI. Thus, IMP treatment within 6 h after TBI limits inflammatory responses and gliosis, improves anatomical and behavioral outcomes and prevents detrimental changes in gene expression in both neural and non-neural cellular elements of the brain.

This prospective cohort study analyzed symptom severity, recovery, and return-to-play (RTP) times reported post-SRC using data collected as part of the Pac-12 Concussion Assessment, Research and Education Affiliated Program and Health Analytics Program.
