The role of clinical and demographic predictors for understanding the cognitive impairment in Spinal Cord Injury (SCI) patients. Spinal Cord 2024:10.1038/s41393-024-00986-7. [PMID: 38609569 DOI: 10.1038/s41393-024-00986-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Revised: 03/14/2024] [Accepted: 03/20/2024] [Indexed: 04/14/2024]
Abstract
STUDY DESIGN Using a cross-sectional design, we extracted sociodemographic and clinical data from 488 Spinal Cord Injury (SCI) patients during their initial assessment before receiving intensive rehabilitation treatment. OBJECTIVES The primary objectives of this study were to ascertain the prevalence of cognitive impairment in the study sample and specify the key clinical and demographic predictors of cognitive functioning in SCI patients. SETTING Lucy Montoro Rehabilitation Institute (LMRI), University of Sao Paulo, Sao Paulo, Brazil. METHODS We utilized independent univariate and multivariate regression models with the Montreal Cognitive Assessment (MoCA) scale, adapted for individuals with visual impairment. Moreover, we consider scores from the execution tasks (visuospatial/executive) as the dependent variable. RESULTS Our findings demonstrate that approximately 80% of the evaluated study sample exhibited cognitive impairment. Through the multivariate regression models, we show that several factors, including age, education, depression levels, and the use of analgesics and/or opioids, are significant predictors of total cognitive scores. These factors are independent of the clinical features associated with SCI, such as age, sex, education, and time since the injury. CONCLUSIONS The results indicate a high prevalence of significant cognitive impairment within the sample, with age, education, depression levels, and the use of analgesics and/or opioids emerging as the primary predictors of total cognitive scores, independent of the clinical features correlated to SCI. These findings hold significant implications for both clinical research and practice, offering valuable guidance for comprehensive management throughout hospitalization and rehabilitation.

Acute non-traffic traumatic spinal cord injury in the aging population: Analysis of the National Inpatient Sample 2005-2018. J Orthop Sci 2024:S0949-2658(24)00047-2. [PMID: 38565448 DOI: 10.1016/j.jos.2024.03.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Revised: 02/22/2024] [Accepted: 03/07/2024] [Indexed: 04/04/2024]
Abstract
BACKGROUND This study aimed to determine risk factors for poor in-hospital outcomes in a large cohort of older adult patients with acute non-traffic traumatic spinal cord injury (tSCI). METHODS This is a population-based, retrospective, observational study. Data of older adults ≥65 years with a primary discharge diagnosis of acute non-traffic tSCI were extracted from the US National Inpatient Sample (NIS) database 2005-2018. Traffic-related tSCI admissions or patients lacking complete data on age, sex and outcomes of interest were excluded. Univariate and multivariate logistic regression analysis was used to determine associations between variables and in-hospital outcomes. RESULTS Data of 49,449 older patients (representing 246,939 persons in the US) were analyzed. The mean age was 79.9 years. Multivariable analyses revealed that severe International Classification of Disease (ICD)-based injury severity score (ICISS) (adjusted odds ratio [aOR] = 3.14, 95% confidence interval [CI]: 2.77-3.57), quadriplegia (aOR = 2.79, 95%CI: 2.34-3.32), paraplegia (aOR = 2.60, 95%CI:1.89-3.58), cervical injury with vertebral fracture (aOR = 2.19, 95%CI: 1.90-2.52), and severe liver disease (aOR = 2.33, 95%CI: 1.34-4.04) were all strong independent predictors of in-hospital mortality. In addition, malnutrition (aOR = 3.19, 95% CI: 2.93-3.48) was the strongest predictors of prolonged length of stay (LOS). CONCLUSIONS Several critical factors for in-hospital mortality, unfavorable discharge, and prolonged LOS among US older adults with acute non-traffic tSCI were identified. In addition to the factors associated with initial severity, the presence of severe liver disease and malnutrition emerged as strong predictors of unfavorable outcomes, highlighting the need for special attention for these patient subgroups.

Abstract
PURPOSE OF REVIEW To provide an overview of recent studies discussing novel strategies, controversies, and challenges in the management of severe traumatic brain injury (sTBI) in the initial postinjury hours. RECENT FINDINGS Prehospital management of sTBI should adhere to Advanced Trauma Life Support (ATLS) principles. Maintaining oxygen saturation and blood pressure within target ranges on-scene by anesthetist, emergency physician or trained paramedics has resulted in improved outcomes. Emergency department (ED) management prioritizes airway control, stable blood pressure, spinal immobilization, and correction of impaired coagulation. Noninvasive techniques such as optic nerve sheath diameter measurement, pupillometry, and transcranial Doppler may aid in detecting intracranial hypertension. Osmotherapy and hyperventilation are effective as temporary measures to reduce intracranial pressure (ICP). Emergent computed tomography (CT) findings guide surgical interventions such as decompressive craniectomy, or evacuation of mass lesions. There are no neuroprotective drugs with proven clinical benefit, and steroids and hypothermia cannot be recommended due to adverse effects in randomized controlled trials. SUMMARY Advancement of the prehospital and ED care that include stabilization of physiological parameters, rapid correction of impaired coagulation, noninvasive techniques to identify raised ICP, emergent surgical evacuation of mass lesions and/or decompressive craniectomy, and temporary measures to counteract increased ICP play pivotal roles in the initial management of sTBI. Individualized approaches considering the underlying pathology are crucial for accurate outcome prediction.

Dual diagnosis of TBI and SCI: an epidemiological study in the pediatric population. Front Neurol 2023; 14:1241550. [PMID: 37830098 PMCID: PMC10565222 DOI: 10.3389/fneur.2023.1241550] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Accepted: 09/04/2023] [Indexed: 10/14/2023] Open
Abstract
Introduction Dual diagnosis (DD) with traumatic brain injury (TBI) and spinal cord injury (SCI) poses clinical and rehabilitation challenges. While comorbid TBI is common among adults with SCI, little is known about the epidemiology in the pediatric population. The primary objective of this study was to evaluate the prevalence of TBI among children in the United States hospitalized with SCI. Secondary objectives were to compare children hospitalized with DD with those with isolated SCI with regards to age, gender, race, hospital length of stay, and hospital charges. Methods A retrospective analysis of hospital discharges among children aged 0-18 years occurring between 2016-2018 from U.S. hospitals participating in the Kids' Inpatient Database. ICD-10 codes were used to identify cases of SCI, which were then categorized by the presence or absence of comorbid TBI. Results 38.8% of children hospitalized with SCI had a co-occurring TBI. While DD disproportionately occurred among male children (67% of cases), when compared with children with isolated SCI, those with DD were not significantly more likely to be male. They were more likely to be Caucasian. The mean age of children with DD (13.2 ± 5.6 years) was significantly less than that of children with isolated SCI (14.4 ± 4.3 years). DD was associated with longer average lengths of stay (6 versus 4 days) and increased mean total hospital charges ($124,198 versus $98,089) when compared to isolated SCI. Conclusion Comorbid TBI is prevalent among U.S. children hospitalized with SCI. Future research is needed to better delineate the impact of DD on mortality, quality of life, and functional outcomes.

Difficulties capturing co-occurring traumatic brain injury among people with traumatic spinal cord injury: a population-based study. Spinal Cord 2023; 61:22-26. [PMID: 36114238 PMCID: PMC9836930 DOI: 10.1038/s41393-022-00851-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Revised: 08/23/2022] [Accepted: 08/26/2022] [Indexed: 01/17/2023]
Abstract
STUDY DESIGN This is a population-based prospective cohort study. OBJECTIVES Traumatic brain injury (TBI) is common among people with traumatic spinal cord injury (TSCI), but rates vary across studies associated with variable approaches to diagnosis. We aimed to determine if a published diagnostic algorithm could be consistently applied to capture co-occurring TBI among persons sustaining TSCI. SETTING One of two spinal centres in New Zealand (NZ), the Burwood Spinal Unit (BSU) captures approximately 45% of NZ TSCI admissions. METHODS Adults (age 16+) with TSCI admitted to the BSU between 1 January 2021 and 31 August 2021 (n = 51) were included. Clinical notes were audited prospectively to identify co-occurring TBI. RESULTS We identified co-occurring TBI in 39% of TSCI cases with a small number of additional suspected TBI cases where TBI could not be confidently ruled in or out. Including all TBI cases, suspected or otherwise resulted in up to 55% of the sample having sustained co-occurring TBI. There were difficulties applying the published algorithm, associated with inconsistent documentation of TBI indicators from acute to rehabilitation contexts. CONCLUSIONS In this study, the feasibility of a TBI diagnostic algorithm for the TSCI population was low. Alternative approaches to screening for TBI among people sustaining TSCI are needed. Greater consistency in documenting TBI across the continuum of care will ensure TBI if present, is included in treatment planning.

Abstract
Spinal cord injury (SCI) is a catastrophic event with multiple comorbidities including spastic paralysis, sensory loss, autonomic dysfunction with sympathetic blunting, neurogenic orthostatic hypotension, neurogenic restrictive and obstructive lung disease, neuropathic pain, spasticity, neurogenic bladder, neurogenic bowel, immobilization hypercalcemia, osteopenia/osteoporosis, neurogenic obesity, and metabolic dysfunction. Cervical and thoracic SCI is all too often accompanied by traumatic brain injury (TBI), which carries its own set of comorbidities including headaches, seizures, paroxysmal sympathetic hyperactivity, aphasia, dysphagia, cognitive dysfunction, memory loss, agitation/anxiety, spasticity, bladder and bowel incontinence, and heterotopic ossification. This manuscript will review the etiology and epidemiology of dual diagnoses, assessment of both entities, and discuss some of the most common comorbidities and management strategies to optimize functional recovery.

Abstract
Objective: To compare pre- and post-injury job type distributions of individuals with spinal cord injury (SCI) living in Switzerland.Design: Cross-sectional, self-report survey.Setting: Community.Participants: Two hundred sixty-three individuals reporting a pre- and 677 a post-injury job title in the Swiss SCI Cohort Study community survey.Interventions: Not applicable.Outcome Measures: Job titles were elicited by free-text questions and classified using the International Standard Classification of Occupations (ISCO-08). Frequencies across ISCO-08 major groups were calculated and compared to Swiss labor market statistics for 1995 and 2011.Results: Compared to pre-SCI, Professionals (16.3% vs 31.2%) and Clerical Support Workers (11.7% vs 19.1%) were more prevalent and Crafts and Related Workers (26.5% vs 5.4%) less common post-injury. Except for Clerical Support Workers, these results reflect recent structural changes in the Swiss labor market.Conclusion: The higher post-SCI prevalence of jobs predominantly requiring cognitive and communication skills compared to rather physically oriented jobs mirrors structural changes in the labor market, except for clerical jobs. Future return-to-work strategies should not primarily target the clerical sector with its diminishing job opportunities, but promote vocational re-training towards jobs requiring higher education and assistive technology to return individuals with limited cognitive resources to physically oriented jobs.

Abstract
INTRODUCTION Evidence of the effect of comorbid spinal cord injury (SCI) on cognitive outcomes in persons undergoing rehabilitation following newly diagnosed traumatic brain injury (TBI) is limited. We conducted a population-based study to investigate this effect. OBJECTIVE To compare cognitive outcomes in patients with TBI with and without a comorbid SCI. SETTING/PARTICIPANTS Adult patients diagnosed with TBI were identified and followed for 1 year through provincial health administrative data; those who entered inpatient rehabilitation were studied. DESIGN A retrospective matched cohort study using the National Rehabilitation Reporting System data of all acute care and freestanding rehabilitation hospitals in Ontario, Canada. MAIN MEASURES The exposure was a comorbid SCI in patients with diagnosed TBI. Exposed patients were matched to unexposed (TBI-only) on sex, age, injury severity, and income, in a ratio of one to two. Gain differences in the cognitive subscale of the Functional Independence Measure were compared between exposed and unexposed patients using multivariable mixed linear model, controlling for comorbidity propensity score, gains in motor function, and rehabilitation care indicators. RESULTS Over the first year post injury, 12 750 (0.84%) of all TBI patients entered inpatient rehabilitation, of whom 1359 (10.66%) had a comorbid SCI. A total of 1195 exposed patients (65.4% male, mean age 50.9 ± 20.6 for male and 61.8 ± 21.8 for female patients) were matched to 2390 unexposed patients. Controlling for confounding, exposed patients had lower cognitive gain (beta -0.43; 95% CI -0.72, -0.15), for both male (beta -0.39; 95% CI -0.75, -0.03) and female (beta -0.51; 95% CI -0.97, -0.05) patients. The adverse effects of comorbid SCI were driven largely by lower gains in problem solving and comprehension. CONCLUSIONS Adult patients with TBI and comorbid SCI showed a lower cognitive domain response to inpatient rehabilitation than patients with TBI alone. Identifying patients at risk for worse cognitive outcomes may facilitate the development of targeted strategies that improve cognitive outcomes.

Abstract
INTRODUCTION Patients with multiple injuries including spinal cord injury (SCI) have low survivability. Little is known for the effect of SCI in their rehabilitation process. PURPOSE To define differences in characteristics and outcomes during the rehabilitation of multiple injured patients with SCI compared to other polytrauma patients. MATERIALS AND METHODS Electronic libraries provided 425 relevant articles. Applying the criteria, 6 articles were eligible for inclusion in this review. RESULTS The extracted data show that multiple injured patients with SCI have an increased length of stay (LOS) in rehabilitation. Initial functional levels, as also one- and two-years follow-up are also decreased. Similar results were found comparing SCI patients with or without multiple injuries: SCI patients with multiple injuries have an increased LOS and decreased functional levels compared with SCI patients. Finally, there was nota relevance between the circumstances of the injuries, like acts of terror, and the expected rehabilitation outcome. CONCLUSION Due to the rarity of eligible articles and the lack of homogenous accessing tools, a meta-analysis was not possible. There is a lack of a universal evaluation strategy or tool, for the severity of the multiple injured patients aiming at the rehabilitation outcome prognosis. Multiple-injured patients with SCI have longer rehabilitation LOS and functional outcomes compared to other polytrauma patients. Prospective studies are needed for evaluation of the differences according to the severity and the complexity of the injuries and the rehabilitation outcome depending on different rehabilitation methods and strategies.

Abstract
Study design Consensus among international experts. Objectives The objective of this project was to develop the International Spinal Cord Injury/Dysfunction (SCI/D) Education Basic Data Set. Setting International expert working group. Methods The published guidelines for developing the International SCI Basic Data Sets were used to develop the International SCI/D Education Basic Data Set. Existing measures and literature on education and disability were reviewed to develop a preliminary draft of the basic education data set through iterative modifications via biweekly conference calls and email communication. The draft was disseminated to the larger International Workgroup for Development of Pediatric SCI/D Basic Data Sets and then to the members of the International Spinal Cord Society (ISCoS), American Spinal Injury Association (ASIA), and relevant expert groups and interested individuals for comments. All feedback received was taken into consideration before the final data set was approved by ISCoS and ASIA. Results The finalized version of the International SCI/D Education Basic Data Set Version 1.0 contains 16 items divided into three domains: school setting/therapeutic services, school participation/academic success, and barriers/attitudes. Most of the variables have been adapted from established measures. This data set is intended for children and youth up to and including high school, but not for emerging adults in higher education or postsecondary vocational training or trade schools. Conclusion The International SCI/D Education Basic Data Set has been developed for collection of a minimal amount of highly relevant information on the education experience in children and youth with SCI/D. Further validation work is needed. Sponsorship This project was funded by the Rick Hansen Institute, Research Award #G2015-27 (Mulcahey, PI).

OBJECTIVE To pilot a novel email-based information package (Work and SCI) for job-seekers with an acquired spinal cord injury (SCI) or spinal cord dysfunction (SCI/D). STUDY DESIGN Prospective, non-randomized, repeated measures trial. SETTING Community dwelling cohort in Australia. PARTICIPANTS Five people with SCI (mean age 46.4 years, SD = 10.2; 4 female) initially reviewed Work and SCI. Twenty-four with SCI/D subsequently enrolled, of whom 16 (mean age 46.4 years, SD = 11.1; 7 female), completed the intervention. INTERVENTION Intervention participants accessed Work and SCI over a 4-week period. OUTCOME MEASURES Individual changes in pre-post scores for the My Vocational Situation Scale, Job Procurement Self-Efficacy Scale, Patient Health Questionnaire-9 and Life Orientation Test-Revised were examined. RESULTS Reliable change in pre-post scores across outcomes were reported by 38% (n = 6) of participants. Favorable comments on the Work and SCI resource were provided in addition to suggestions for improvement. CONCLUSIONS Preliminary data suggest that Work and SCI may help to establish vocational interests among job-seekers with a SCI/D, however further work is needed to enhance participant compliance. This might include moderator support to promote and maintain participation. A controlled design will also help to identify factors that influence engagement with the Work and SCI resource.

Abstract
OBJECTIVE Explore how traumatic brain injury (TBI) is screened among spinal cord injury (SCI) patients across the continuum of care. DESIGN Retrospective chart review Setting: Emergency department, trauma, inpatient rehabilitation Participants: 325 patients with SCI from inpatient rehabilitation facility (IRF) between March 1, 2011 and December 31, 2014 were screened. 49 eligible subjects had traumatic SCI and received care in adjoining acute care (AC) hospital. OUTCOME MEASURES Demographic characteristics and variables that capture diagnosis of TBI/SCI included documentation from ambulance, emergency department, AC, and IRF including ICD-9 codes, altered mental status, loss of consciousness (LOC), Glasgow Coma Score, Post Traumatic Amnesia (PTA), neuroimaging, and cognitive assessments. RESULTS Participants were male (81%), white (55%), privately insured (49%), and aged 39.3±18.0 years with 51% paraplegic and 49% tetraplegic. Mechanisms of injury were gunshot wound (31%), fall (29%), and motor vehicle accident (20%). TBI occurred in 65% of SCI individuals, however documentation of identification of TBI, LOC, and CT imaging results varied in H&P, discharge notes, and ICD-9 codes across the continuum. Cognitive assessments were performed on 16% of subjects. CONCLUSIONS Documentation showed variability between AC and IRF and among disciplines. Imaging and GCS were more consistently documented than LOC and PTA. It is necessary to standardize screening processes between AC and IRF to identify dual diagnosis.

Abstract
STUDY DESIGN Retrospective single-institution observational study. OBJECTIVE Spinal cord injury (SCI) is associated with a high prevalence of hyponatremia, which can cause various clinical symptoms and increase mortality. We aimed to analyze the risk factors for hyponatremia in patients with acute SCI. SETTING Trauma Center, Tohoku University Hospital, Japan METHODS: We reviewed the medical records of patients with SCI admitted between January 2008 and November 2016. Least angle regression analyses was performed to assess the association between hyponatremia and other parameters. RESULTS Of the 213 enrolled patients, 85 (40%) had hyponatremia (serum Na < 135 mmol/L) whilst 19 (9%) had severe hyponatremia (serum Na < 130 mmol/L). Least angle regression analyses revealed that hyponatremia was significantly associated with higher American Spinal Injury Association impairment scale, nosocomial pneumonia, deep vein thrombosis, bradycardia, and surgery for SCI before developing hyponatremia. Severe hyponatremia was significantly associated with traumatic brain injury with an abbreviated injury scale score ≥3, higher American Spinal Injury Association impairment scale, bradycardia, vasopressors, and nosocomial pneumonia. CONCLUSION Various factors including traumatic brain injury with an abbreviated injury scale score ≥3 and higher American Spinal Injury Association impairment scale may be associated with hyponatremia in patients with acute SCI. These factors can help clinicians identify and monitor SCI patients with a higher hyponatremia risk, and potentially help patients to avoid severe complications.

Abstract
PURPOSE/OBJECTIVE To compare the cognitive profiles of a well-characterized sample of adults with and without spinal cord injury (SCI) using the NIH Toolbox Cognition Battery NIHTB-CB. Research Method/Design: Participants were 156 community-dwelling individuals with SCI recruited from 3 academic medical centers, and 156 individuals without SCI selected from the NIHTB-CB normative database (N = 312). The main outcome measures were the demographically adjusted NIHTB-CB subtest and composite scores. RESULTS Individuals with and without SCI performed equivalently on the NIHTB-CB crystallized composite score, suggesting comparable premorbid functioning. Individuals with SCI produced lower scores on the NIHTB-CB fluid composite score by an average of 4.5 T-score points (Cohen's d = 0.50; a medium effect size). As a group, individuals with SCI had the most difficulty on tests of processing speed and executive functions, and some difficulty on a test of episodic memory, although effect sizes were small. These differences remained even after accounting for fine motor speed and dexterity. Individuals with tetraplegia produced lower scores than individuals with paraplegia on tests of processing speed and executive functioning. CONCLUSION/IMPLICATIONS Community-dwelling individuals with SCI are at elevated risk of mild cognitive difficulties, particularly on tasks that rely on processing speed and executive functions. The NIHTB-CB is relatively brief, samples important cognitive domains, has good normative data, and is appropriate for some individuals with SCI (those who have functional use of one hand). The battery has standardized accommodations for individuals with minor motor limitations, but timed tests are inaccessible for individuals who are unable to perform rapid button presses.

[PMID: 29584506 DOI: 10.1080/15389588.2017.1410144] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/29/2017] [Accepted: 11/22/2017] [Indexed: 06/08/2023]
Abstract
BACKGROUND The Abbreviated Injury Scale (AIS) is an internationally accepted coding system created by the Association for the Advancement of Automotive Medicine, utilized to code traumatic injuries as a function of severity, the latter often defined as mortality risk. Periodic reassessment of that risk is prudent, in light of advances in health care and relationship of nonanatomic factors to death. OBJECTIVE The objective of this study was to reevaluate the risk of death associated with spine fractures with and without neurologic deficit, age factors associated with it, and the impact of hospital coding on the accuracy of these efforts. METHODS Medical records and imaging of patients treated at a level 1 trauma center from 2014 through 2016 with discharge International Classification of Diseases, 10th revision (ICD-10) diagnoses of spinal trauma and spinal cord injury (SCI) were reviewed. Data were collected on demographics, complications, neurologic status, and outcomes. RESULTS Three hundred seventy patients met the criteria for inclusion in this effort. Errors in ICD-10 discharge codes were seen in 45% of the cases, both false positive and negative. One hundred thirty-four patients, with a mean age of 45, were admitted with neurologic deficit. There were 8 SCI-related deaths; 2 were postoperative out of 110 undergoing surgical treatment. All deaths in this group were in patients with upper level SCI, with a mean age of 68. Ten patients had spontaneous neurologic improvement within 24 h. One hundred nineteen patients without deficit had AIS 2 scored fractures; there was one postoperative death out of 47 patients undergoing surgical treatment. One hundred seventeen patients without deficit suffered AIS 3 fractures; 66 underwent surgery without any deaths. There was one nonoperative death. Age and high quadriplegia were the only factors associated with mortality. CONCLUSIONS Mortality risk in patients with deficit was associated more with age at injury than extent of anatomic injury. Spine trauma without neurologic deficit is benign in younger populations and AIS scores could be age adjusted. Mortality risk is higher in high cervical injuries with neurologic deficit and in the elderly. An incidental finding is that demographic studies based solely on discharge ICD coding may contain errors and should be considered critically.

Diffusion Tensor Tractography for Detection of Concomitant Traumatic Brain Injury in Patients With Traumatic Spinal Cord Injury. J Head Trauma Rehabil 2017; 32:E44-E49. [PMID: 28422895 DOI: 10.1097/htr.0000000000000300] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
OBJECTIVES We investigated concomitant traumatic brain injury in patients with traumatic spinal cord injury (TSCI) who had head trauma history, using diffusion tensor tractography (DTT). DESIGN Retrospective survey. PARTICIPANTS We recruited 14 consecutive patients with TSCI and coexisting head trauma history at the time of TSCI and 30 control subjects. METHODS The corticospinal tract (CST), corticoreticulospinal tract (CRT), cingulum, and fornix were reconstructed using DTT, and DTT parameters (fractional anisotropy and fiber volume) and configuration were estimated. RESULTS The values of fractional anisotropy and fiber volume in the CST, CRT, cingulum, and fornix of the patient group were significantly lower than those of the control group (P < .05). On configurational analysis of DTT for each tract, the neural tracts for motor function (the CST and CRT) had more injury than the neural tracts for cognitive function (the cingulum and fornix). No association between the severity of TSCI and traumatic brain injury was observed in terms of DTT parameters. CONCLUSIONS Using DTT, we found injury of the neural tracts in patients with head trauma history at the time of TSCI. Our results suggest that brain evaluation using DTT can be recommended for the patients with head trauma history at the time of TSCI irrespective of the results of conventional brain MRI.

Comorbid Traumatic Brain Injury and Spinal Cord Injury: Screening Validity and Effect on Outcomes. Arch Phys Med Rehabil 2016; 97:1628-34. [PMID: 27084266 DOI: 10.1016/j.apmr.2016.03.008] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2015] [Revised: 03/16/2016] [Accepted: 03/16/2016] [Indexed: 10/21/2022]
Abstract
OBJECTIVES To determine the diagnostic accuracy of a self-report measure of traumatic brain injury (TBI) in people with spinal cord injury (SCI), and to assess the potential effect of TBI on acute and postacute outcomes. DESIGN Incident TBI as determined by self-report was compared with systematic medical records review by physicians blinded to self-reported TBI. SETTING Inpatient rehabilitation unit. PARTICIPANTS From 155 consecutive admissions, participants (N=105; 73% men; mean age, 45.9y; 73% white; 58% with tetraplegia) who met inclusion criteria and were admitted on the day of injury were recruited and assessed. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURE Step 2 of the Traumatic Brain Injury-4 (TBI-4) interview was used to estimate the presence and severity of TBI. RESULTS Estimated incidence of TBI was 33% by chart review and 60% based on Step 2 of the TBI-4. Ninety-one percent of those with TBI based on chart review sustained mild injuries. At the optimal cutoff of "possible TBI," the TBI-4 had a sensitivity of 83% (95% confidence interval, 66%-93%), a specificity of 51% (95% confidence interval, 39%-64%), and a Youden Index of 0.3 (95% confidence interval, 0.2-0.5). Compared with those without TBI, those with chart review-determined TBI had nonsignificant trends toward a longer acute care length of stay and a higher functional status at rehabilitation discharge, but equivalent 1-year outcomes. CONCLUSIONS Step 2 of theTBI-4 did not meet Youden's criteria (≥0.8) for good diagnostic accuracy in the context of recent SCI. Comorbid TBIs were almost exclusively mild and not associated with poorer outcomes 1 year after SCI.

MicroRNA-9 controls apoptosis of neurons by targeting monocyte chemotactic protein-induced protein 1 expression in rat acute spinal cord injury model. Brain Res Bull 2016; 121:233-40. [PMID: 26812136 DOI: 10.1016/j.brainresbull.2016.01.011] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2015] [Revised: 12/30/2015] [Accepted: 01/21/2016] [Indexed: 01/07/2023]
Abstract
OBJECTIVE For the purpose of an early identification of intervention targets for acute spinal cord injury (ASCI), we investigated the changes in expression levels of microRNA-9 (miR-9) and MCPIP1 in rat ASCI model. METHOD A total of 108 healthy rats were randomly divided into non-ASCI group (n=18) and five ASCI groups, 6h, 12h, 24h, 3 days and 7 days, representing the experimental time points following ASCI (n=18 per group). Hematoxylin and eosin (HE) staining was used to assess the ASCI damage, and quantitative real-time PCR (qRT-PCR) and in situ hybridization (ISH) were employed for the detection of miR-9 and MCPIP1 mRNA expression. RESULTS HE staining results showed normal neuronal morphology in the non-ASCI group, but spinal cord tissue at 6h after ASCI showed developing neuronal necrosis. Acute inflammatory response was evident at 12h and 24h, with immune cells infiltrating into the gray matter. Vascular permeability increased and the nerve cells in gray-white matter exhibited extensive damage and necrosis at 24h and 7 days after ASCI. MiR-9 expression in ASCI tissue was significantly lower than that in normal spinal cord tissue. Statistical analysis showed a significant decrease in miR-9 expression in all the ASCI groups, compared to the non-ASCI group. Results from real-time PCR analysis revealed that MCPIP1 expression in all the ASCI groups was significantly higher than the non-ASCI group, and MCPIP1 expressions gradually increased with times at 6h-24h after ASCI. ISH revealed the following results after ASCI (1) miR-9 and MCPIP1 mRNA expression mainly distributed in ventral horn motor neurons, (2) miR-9 expression was high at 7 day after ASCI and (3) in the non-ASCI group, MCPIP1 expression was high at 6h, 12h, 24h and 3 days. CONCLUSION MCPIP1 is significantly up-regulated after ASCI. The negative relationship between MCPIP1 and miR-9 suggest that MCPIP1 mRNA could be a target of miR-9 during ASCI. Thus, miR-9 is a marker for apoptosis in neurons, and an excellent therapeutic target for ASCI patients.

Abstract
Research scientists and clinicians should be aware that missed diagnoses of mild-moderate traumatic brain injuries in post-acute patients having spinal cord injuries may approach 60-74% with certain risk factors, potentially causing clinical consequences for patients, and confounding the results of clinical research studies. Factors leading to a missed diagnosis may include acute trauma-related life-threatening issues, sedation/intubation, subtle neuropathology on neuroimaging, failure to collect Glasgow Coma Scale scores or duration of posttraumatic amnesia, or lack of validity of this information, and overlap in neuro-cognitive symptoms with emotional responses to spinal cord injuries. Strategies for avoiding a missed diagnosis of mild-moderate traumatic brain injuries in patients having a spinal cord injuries are highlighted in this perspective.
