Unfortunately, E-ABT after TSCI has never been attempted in humans due to practical obstacles and potential safety concerns. This study aims to report on the safety and feasibility outcomes of the Protocol for Rapid Onset of Mobilization in Patients with Traumatic SCI (PROMPT-SCI) trial: the first-ever trial of E-ABT in critically ill patients who suffered a severe TSCI. To do so, 45 patients with severe TSCI were recruited to participate in the PROMPT-SCI trial between April 2021 and August 2023. The intervention consisted of daily 30-min sessions of motor-assisted in-bed leg cycling for 14 days, starting within 48 h of early surgery (≈72 h from the initial trauma). Adverse events were closely monitored, and completion rates were evaluated. Out of the 45 participants, 36 (80%) completed a full and safe session within 48 h of surgery and all participants managed to achieve this outcome within 72 h of surgery. Over the full 14-day protocol, the average completion rate of sessions was 87.2 ± 22.7% (range: 7.1-100.0%). A total of three patients were mechanically ventilated during the protocol and all three had 100% completion of sessions. Frequent reasons for unattempted/incomplete sessions were scheduling conflicts with activities related to care (e.g., bronchoscopy) and fatigue/uncontrolled pain before initiating cycling. We also report no neurological deterioration caused by cycling and no major adverse event recorded during or between sessions. In conclusion, this study suggests that E-ABT can be safely initiated within 48-72 h after a severe TSCI with no major adverse event. In the form of daily passive in-bed leg cycling, E-ABT is also acceptable for target users, and feasible over the course of the first weeks after the initial trauma, as shown by our excellent rate of completed sessions (87%). The present results also suggest that improved collaboration with intensive care unit staff, including intensivists and nurses, could improve these rates even further.</p>","PeriodicalId":16512,"journal":{"name":"Journal of neurotrauma","volume":" ","pages":"242-249"},"PeriodicalIF":3.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142750951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, the disrupted FNC between salience network and ECN in state 2 and the number of transitions were all positively correlated with neurological scores in patients with SCI.

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.

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.
