Similarly, SCI patients treated with high doses of opioid for the first 24 h postinjury have increased symptoms of chronic pain 1 year later. Whether these adverse effects are driven by morphine only or all opioids compromise recovery after SCI, however, is unknown. Based on our previous findings we hypothesized that activation of the kappa opioid receptor (KOR) is key in the morphine-induced attenuation of locomotor recovery after SCI. Thus, we posited that opioids that engage KOR-mediated signaling pathways (morphine, oxycodone) would undermine recovery, and clinically relevant opioids with less KOR activity (fentanyl and buprenorphine) would not. To test this, we compared the effects of the clinically relevant opioids on locomotor recovery and pain in a male rat spinal contusion model. Rats were given a moderate spinal contusion injury followed by 7 days of intravenous morphine, oxycodone, fentanyl, buprenorphine, or saline, and recovery was assessed for 28 days. All opioids produced analgesia on tests of thermal, mechanical, and incremented shock reactivity. However, tolerance developed rapidly with buprenorphine administration, particularly with daily administrations of 5 morphine milligram equivalent (MME) buprenorphine. Opioid-induced hyperalgesia (OIH) also developed across days following administration of higher doses (10 MME, 20 MME) of morphine and oxycodone. Fentanyl and buprenorphine did not produce OIH. Contrary to our hypothesis, however, we found that high doses of all opioids reduced recovery of locomotor function. Unlike the other opioids, the effects of buprenorphine on locomotor recovery appeared transient, but it also produced chronic pain. Morphine, oxycodone, and buprenorphine decreased reactivity thresholds on tests of mechanical and incremented shock stimulation. In sum, all opioids undermined long-term recovery in the rat model. Further interrogation of the molecular mechanisms driving the adverse effects is essential. This study provides critical insight into pain management strategies in the acute phase of SCI and potential long-term consequences of early opioid administration.</p>","PeriodicalId":16512,"journal":{"name":"Journal of neurotrauma","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143255813","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}

We retrospectively collected and analyzed data from 230 patients with GSWH admitted to our Level 1 trauma center between May 1, 2018, and October 31, 2023. HCT images obtained on hospital arrival were evaluated for predefined imaging features by two blinded readers and arbitrated, when needed, by a third. The average contribution of each radiological feature to mortality at hospital discharge was assessed using a SuperLearner ensemble model trained on ∼77% of the cohort. Each feature's contribution was scaled to ensure the additive final score per patient ranged between 0 and 100. The HCT features predicting in-hospital mortality, ranked from highest to lowest importance, were transhemispheric projectile below the level of the third ventricle (18 [16.8, 19.9]), presence of blood in the lateral ventricles (ventricles casted) (18[16.8, 19.6]), brainstem involvement (14 [12.7, 15.1]), transhemispheric projectile above the level of the third ventricle (11 [9.7, 11.6]), presence of any amount of blood in the ambient cistern (9[8.2, 10]), presence of any amount of blood in the lateral ventricles (9 [7.9, 9.8]), cerebellar involvement (9 [7.9, 9.5]), any evidence of ventricular effacement (4 [3.4, 4.6]), midline shift (MLS) &gt;0 mm (4 [3.4, 4.4]), perforating injury (3 [2.4, 3.2]), and presence of an intracerebral hematoma (ICH) &gt;20 mm in the largest diameter (2 [1.4, 1.9]). The UChicago PBI Imaging score showed a strong performance, achieving an area under the curve (AUC) of 0.86 (95% CI: [0.77, 0.96]) on a test set of 56 patients who were not included in model training. This indicates better prediction accuracy compared to both the Rotterdam score (AUC 0.8, 95% CI: [0.68, 0.96]) and the Marshall score (AUC 0.66, 95% CI: [0.52, 0.81]). Our model performed particularly well for patients with a Glasgow Coma Scale (GCS) score between 5 and 9. In this range, our model's performance (AUC 0.86) remained stable, while the Rotterdam and Marshall Scores showed notably lower predictive accuracy, with AUCs of 0.61 and 0.52, respectively. A dedicated evaluation of GSWH HCT reveals an association between disease burden, as quantified by unique features not native to blunt TBI imaging models, and mortality. Specifically, transhemispheric injury below the level of the third ventricle along with blood-casting bilateral ventricles and brainstem involvement was highly associated with mortality. The model is optimized for intermediate GCS scores where greater prognostic uncertainty exists.

The TBI model was induced in C57BL/6 mice through a controlled cortical impact device, and an <i>in vitro</i> BBB model was established using Transwell chambers. Western blot (WB) analysis was used to evaluate NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome and nuclear factor-kappaB (NF-κB) pathway proteins. Flow cytometry and transendothelial electrical resistance (TEER) were employed to assess endothelial cell apoptosis levels and BBB integrity. ELISA was utilized to measure cytokines interleukin-1β (IL-1β) and matrix metalloproteinase-9 (MMP-9). Immunofluorescence techniques were used to evaluate protein levels and the nuclear translocation of the rela (p65) subunit. The Evans blue dye leakage assay and the brain wet-dry weight method were utilized to assess BBB integrity and brain swelling. Inhibition of NKCC1 reduced the level of NLRP3 inflammasome and the secretion of IL-1β and MMP-9 in microglia. Additionally, NKCC1 inhibition suppressed the activation of the NF-κB signaling pathway, which in turn decreased the level of NLRP3 inflammasome. The presence of NLRP3 inflammasome in BV2 cells led to compromised BBB integrity within an inflammatory milieu. Following TBI, an upregulation of NLRP3 inflammasome was observed in microglia, astrocytes, vascular endothelial cells, and neurons. Furthermore, inhibiting NKCC1 resulted in a decrease in the positive rate of NLRP3 inflammasome in microglia and the levels of inflammatory cytokines IL-1β and MMP-9 after TBI, which correlated with BBB damage and the development of cerebral edema. These findings demonstrate that the suppression of the NKCC1 cotransporter protein alleviates BBB disruption through the NF-κB/NLRP3 signaling pathway following TBI.</p>","PeriodicalId":16512,"journal":{"name":"Journal of neurotrauma","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143066098","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}

This study was an observational analysis of the OXY-TC multicenter randomized clinical trial between June 15, 2016 and April 17, 2021. Recruited patients had a pre-hospital Glasgow Coma Scale (GCS) score of 3-8, mechanical ventilation, and intracranial pressure (ICP) with or without brain tissue oxygen pressure (PbtO₂) monitoring. Objectives were to maintain ICP at 20 mmHg or below and PbtO2 above 20 mmHg at all times. The primary end-point was the proportion of women and men with poor outcomes at 6 months, corresponding to an extended Glasgow Outcome Scale (GOSE) score of 1-4 (death to upper severe disability). Of 318 randomized patients, 200 men and 71 women were analyzed. They were comparable in age, comorbidities, and initial injury severity scores. However, women had larger doses of ICP as the proportion of monitoring time of ICP above 20 mmHg 8% (3-18; median, interquartile range) versus 3% (1-10), respectively (<i>p</i> = 0.002).

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.

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.

There were areas of agreement (e.g., early education was ranked highly by all groups) and discordance (e.g., people with lived experience perceived diagnostic tests/investigations as more important than the other groups). We synthesized the prioritization survey results into a top-10 list of the highest priority clinical actions. This list will inform implementation efforts aimed at improving post-acute care for nonhospitalized TBI.</p>","PeriodicalId":16512,"journal":{"name":"Journal of neurotrauma","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142932036","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}
