RESUMO

STUDY DESIGN: Cross-Sectional Study. OBJECTIVES: To investigate the changes in the characteristics of cervical spinal cord injuries (CSCI) before and after the coronavirus disease 2019 (COVID-19) pandemic among patients transported to our hospital in Japan. SETTING: Hospital with an emergency center in Chiba, Japan. METHODS: Patients eligible for the study were those transported within 24 h of injury and diagnosed with cervical spinal cord injury between January 2018 and December 2021 at our hospital. Medical records were retrospectively examined to investigate the number and characteristics of patients with CSCI. The clinical variables of patients with CSCI were compared according to the time of admission as related to the COVID-19 pandemic: 2018-19 (before) or 2020-21 (after). RESULTS: The total number of patients with CSCI from 2018 to 2021 was 108, with 57 before the COVID-19 pandemic and 51 after the COVID-19 pandemic. The number of severe cases with an injury severity score (ISS) of >16 decreased after COVID-19 (p < 0.05). Falls on level surfaces were the most common cause of injury both before and after COVID-19. Although the ranking of traffic accidents decreased after COVID-19, among those, the number of bicycle injuries tended to increase. CONCLUSIONS: The number of serious cases with an ISS > 16 decreased, presumably because of the decline in high-energy trauma due to the background decrease in the number of traffic accidents.

RESUMO

The present research focused on identifying necroptosis-related differentially expressed genes (NRDEGs) in spinal cord injury (SCI) to highlight potential therapeutic and prognostic target genes in clinical SCI. Three SCI-related datasets were downloaded, including GSE151371, GSE5296 and GSE47681. MSigDB and KEGG datasets were searched for necroptosis-related genes (NRGs). Differentially expressed genes (DEGs) and NRGs were intersected to obtain NRDEGs. The MCC algorithm was employed to select the first 10 genes as hub genes. A protein-protein interaction (PPI) network related to NRDEGs was developed utilizing STRING. Several databases were searched to predict interactions between hub genes and miRNAs, transcription factors, potential drugs, and small molecules. Immunoassays were performed to identify DEGs using CIBERSORTx. Additionally, qRT-PCR was carried out to verify NRDEGs in an animal model of SCI. Combined analysis of all datasets identified 15 co-expressed DEGs and NRGs. GO and KEGG pathway analyses highlighted DEGs mostly belonged to pathways associated with necroptosis and apoptosis. Hub gene expression analysis showed high accuracy in SCI diagnosis was associated with the expression of CHMP7 and FADD. A total of two hub genes, i.e. CHMP7, FADD, were considered potential targets for SCI therapy.

RESUMO

OBJECTIVE: This article provides a review of the initial clinical and radiologic evaluation and treatment of patients with traumatic spinal cord injuries. It specifically highlights essential knowledge for neurologists who encounter patients with these complex injuries. LATEST DEVELOPMENTS: There has been improvement in the care of patients with traumatic spinal cord injuries, particularly in the prehospital evaluation, approach for immediate immobilization, standardized spinal clearance, efficient triage, and transportation of appropriate patients to traumatic spinal cord injury specialized centers. Advancements in spinal instrumentation have improved the surgical management of spinal fractures and the ability to manage patients with spinal mechanical instability. The clinical evidence favors performing early surgical decompression and spine stabilization within 24 hours of traumatic spinal cord injuries, regardless of the severity or location of the injury. There is no evidence that supports the use of neuroprotective treatments to improve outcomes in patients with traumatic spinal cord injuries. The administration of high-dose methylprednisolone, which is associated with significant systemic adverse effects, is strongly discouraged. Early and delayed mortality rates continue to be high in patients with traumatic spinal cord injuries, and survivors often confront substantial long-term physical and functional impairments. Whereas the exploration of neuroregenerative approaches, such as stem cell transplantation, is underway, these methods remain largely investigational. Further research is still necessary to advance the functional recovery of patients with traumatic spinal cord injuries. ESSENTIAL POINTS: Traumatic spinal cord injury is a complex and devastating condition that leads to long-term neurologic deficits with profound physical, social, and vocational implications, resulting in a diminished quality of life, particularly for severely affected patients. The initial management of traumatic spinal cord injuries demands comprehensive interdisciplinary care to address the potentially catastrophic multisystem effects. Ongoing endeavors are focused on optimizing and customizing initial management approaches and developing effective therapies for neuroprotection and neuroregeneration to enhance long-term functional recovery.

RESUMO

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: To define the prognosis and predictive factors for neurological improvement in older patients with incomplete spinal cord injury (SCI) of American Spinal Injury Association Impairment Scale grade C (AIS-C). SETTINGS: Multi-institutions in Japan. METHODS: We included patients aged ≥65 years with traumatic SCI of AIS-C who were treated conservatively or surgically with >3 follow-up months. To identify factors related to neurological improvement, patients were divided into three groups according to their neurological status at the final follow-up, with univariate among-group comparisons of demographics, radiographic, and therapeutic factors. Significant variables were included in the multivariate logistic regression analysis. RESULTS: Overall, 296 older patients with SCI of AIS-C on admission were identified (average age: 75.2 years, average follow-up: 18.7 months). Among them, 190 (64.2%) patients improved to AIS-D and 21 (7.1%) patients improved to AIS-E at final follow-up. There were significant among-group differences in age (p = 0.026), body mass index (p = 0.007), status of pre-traumatic activities of daily living (ADL) (p = 0.037), and serum albumin concentrations (p = 0.011). Logistic regression analysis showed no significant differences in variables in the stratified group of patients who improved to AIS-D. Meanwhile, serum albumin was a significant variable in patients who improved to AIS-E (p = 0.026; OR: 6.20, pre-traumatic ADL was omitted due to data skewness). CONCLUSIONS: Most older patients with incomplete AIS-C SCI demonstrated at least 1 grade of neurological improvement. However, <10% of patients achieved complete recovery. Key predictors of complete recovery were high serum albumin levels on admission and independent pre-traumatic ADL. SPONSORSHIP: No funding was received for this study.

RESUMO

SUMMARY: Intraoperative neurophysiologic monitoring has added substantially to the safety of spinal deformity surgery correction since its introduction over four decades ago. Monitoring routinely includes both somatosensory evoked potentials and motor evoked potentials. Either modality alone will detect almost all instances of spinal cord injury during deformity correction. The combined use of the two modalities provides complementary information, can permit more rapidly identification of problems, and enhances safety though parallel redundancy should one modality fail. Both techniques are well established and continue to be refined. Although there is room for provider preference, proper monitoring requires attention to technical detail, understanding of the underlying physiology, and familiarity with effects of commonly used anesthetic agents.

RESUMO

STUDY DESIGN: Retrospective study OBJECTIVES: To describe the presenting symptoms/signs, clinical course and outcomes in hospitalised people with spinal cord injury (SCI) and symptomatic COVID-19 infections. SETTING: One university hospital and two SCI centres in Switzerland. METHODS: Descriptive analysis of symptoms/signs, clinical course and outcomes of people with SCI with symptomatic COVID-19 infections and need for hospitalisation. RESULTS: Twenty-two people with SCI were included, 15 (68%) were male, median age 64.5 years (interquartile range, IQR, 52-73 years). Nine (41%) had tetraplegia, and eight (36%) were classified with motor-complete lesions. Frequent clinical symptoms were fever (59%), coughing (54%), fatigue (50%), and dyspnoea (27%). Most frequent complications were bacterial pulmonary superinfection (18%), and acute respiratory distress syndrome (18%). Fifteen persons (68%) needed oxygen therapy during the course of hospitalisation, and 7 (32%) people were ventilated. Median length of stay (LOS) was 23 days (IQR 15-35), varying by age for people under 60 years with a median LOS of 9 days (IQR 8-27), and for those older than 60 years with a median of 34 days (IQR 17-39), respectively. In total, 3 persons (14%) died during hospitalisation, all older with paraplegia. CONCLUSIONS: Typical symptoms like fever and coughing were not present in all people. People with tetraplegia did not demonstrate worse outcomes, on the contrary, they had shorter LOS, no difference in ventilation needs, and no higher mortality compared to people with paraplegia. Older people showed longer LOS. This study recommends close supervision of the SCI population to detect early signs and symptoms of COVID-19 infection.

RESUMO

Evaluating patients with a traumatic spinal cord injury can be complicated by other injuries. In this case, a 24-year-old woman injured by a needlefish presented with combined motor and sensory defects, cranial nerve deficits, and a blunt vascular injury. This case highlights the importance of neurologic and vascular localizations and an understanding of spinal cord injuries involving various ascending and descending tracts. Appreciation of these anatomical considerations through this case illustrates the diagnostic approach to neurologic evaluation. While we present a traumatic etiology for multiple neurologic syndromes, this case gives readers an opportunity to develop a comprehensive differential diagnosis and tailor investigations for other relevant etiologies. Readers walking through this stepwise process will ultimately arrive at several distinct but related diagnoses.

RESUMO

OBJECTIVES: To demonstrate the different techniques used to perform successful penile vibratory stimulation (PVS) to induce ejaculation in men with spinal cord injuries (SCIs). DESIGN: A video demonstration of the PVS procedure performed in men with SCIs using the FertiCare 2.0 medical vibrator. SETTING: Major University Medical Center. PATIENTS: Men with SCIs. INTERVENTION(S): Spinal cord injury is the leading cause of anejaculation in young men. After SCIs, most of these men will need a method of assisted ejaculation to achieve biological fatherhood. In this study, a newly designed and tested vibrator (FertiCare 2.0) was used to induce ejaculation. The initial assessment of each patient included a standard history, physical examination, level of injury determination using the International Standards for Neurological Classification of Spinal Cord Injury as well as assessment of the hip flexor reflex and the bulbocavernosus reflex. Patients with a level of injury at or rostral to T6 were pretreated with 10-40 mg of sublingual nifedipine to manage autonomic dysreflexia. A single vibrator was applied to the dorsum, or frenulum, of the glans penis. Stimulation is delivered in 2-minute increments to a maximum of 10 minutes per visit. Application of two vibrators or abdominal electrical stimulation concurrently with PVS was used in select patients. Ejaculated semen was collected in a sterile cup and examined after liquefaction. Bladder preparation using sperm wash medium was performed in patients suspected of experiencing retrograde ejaculation. MAIN OUTCOME MEASURE(S): Successful ejaculation after performing the PVS procedure in men with SCIs. RESULTS: Penile vibratory stimulation was successful in 86% of men whose level of injury was T10 or rostral. The total motile sperm count in antegrade ejaculates produced using PVS was >5 million (lower limit considered for intrauterine insemination) in 71% of ejaculates. No complications because of PVS were observed in 3,700 trials performed by our group and none in the patients presented in this video. CONCLUSION(S): Penile vibratory stimulation is a safe and effective method for the management of ejaculatory dysfunction in men with SCIs. Penile vibratory stimulation can be performed by the male partner after an initial evaluation by a specialized provider, and the ejaculate can be used to perform home insemination.

RESUMO

The expression of microRNA (miRNA) changes in many diseases plays an important role in the diagnosis, treatment, and prognosis of diseases. Spinal cord injury (SCI) is a serious disease of the central nervous system, accompanied by inflammation, cell apoptosis, neuronal necrosis, axonal rupture, demyelination, and other pathological processes, resulting in impaired sensory and motor functions of patients. Studies have shown that miRNA expression has changed after SCI, and miRNAs participate in the pathophysiological process and treatment of SCI. Therefore, quantitative analysis and monitoring of the expression of miRNA were of great significance for the diagnosis and treatment of SCI. Through the SCI-related miRNA chord plot, we screened out miRNA-21-5p and miRNA-let-7a with a higher correlation. However, for traditional detection strategies, it is still a great challenge to achieve a fast, accurate, and sensitive detection of miRNA in complex biological environments. The most frequently used method for detecting miRNAs is polymerase chain reaction (PCR), but it has disadvantages such as being time-consuming and cumbersome. In this paper, a novel SERS sensor for the quantitative detection of miRNA-21-5p and miRNA-let-7a in serum and cerebrospinal fluid (CSF) was developed. The SERS probe eventually formed a sandwich-like structure of Fe3O4@hpDNA@miRNA@hpDNA@GNCs with target miRNAs, which had high specificity and stability. This SERS sensor achieved a wide range of detection from 1 fM to 1 nM and had a good linear relationship. The limits of detection (LOD) for miRNA-21-5p and miRNA-let-7a were 0.015 and 0.011 fM, respectively. This new strategy realized quantitative detection and long-term monitoring of miRNA-21-5p and miRNA-let-7a in vivo. It is expected to become a powerful biomolecule analysis tool and will provide ideas for the diagnosis and treatment of many diseases.

RESUMO

AIMS: Neurogenic bladder (NB) is a prevalent and debilitating consequence of spinal cord injury (SCI). Indeed, the accurate prognostication of early bladder outcomes is crucial for patient counseling, rehabilitation goal setting, and personalized intervention planning. METHODS: A retrospective exploratory analysis was conducted on a cohort of consecutive SCI patients admitted to a rehabilitation facility in China from May 2016 to December 2022. Demographic, clinical, and electrophysiological data were collected within 40 days post-SCI, with bladder outcomes assessed at 3 months following SCI onset. RESULTS: The present study enrolled 202 SCI patients with a mean age of 40.3 ± 12.3 years. At 3 months post-SCI, 79 participants exhibited complete bladder emptying. Least absolute shrinkage and selection operator (LASSO) and multivariate logistic regression analyses identified the H-reflex of the soleus muscle, the American Spinal Injury Association Lower Extremity Motor Score (ASIA-LEMS), and the time from lesion to rehabilitation facility (TLRF) as significant independent predictors for bladder emptying. A scoring system named HALT was developed, yielding a strong discriminatory performance with an area under the receiver operating characteristics curve (aROC) of 0.878 (95% CI: 0.823-0.933). A simplified model utilizing only the H-reflex exhibited excellent discriminatory ability with an aROC of 0.824 (95% CI: 0.766-0.881). Both models demonstrated good calibration via the Hosmer-Lemeshow test and favorable clinical net benefits through decision curve analysis (DCA). In comparison to ASIA-LEMS, both the HALT score and H-reflex showed superior predictive accuracy for bladder outcome. Notably, in individuals with incomplete injuries, the HALT score (aROC = 0.973, 95% CI: 0.940-1.000) and the H-reflex (aROC = 0.888, 95% CI: 0.807-0.970) displayed enhanced performance. CONCLUSION: Two reliable models, the HALT score and the H-reflex, were developed to predict bladder outcomes as early as 3 months after SCI onset. Importantly, this study provides hitherto undocumented evidence regarding the predictive significance of the soleus H-reflex in relation to bladder outcomes in SCI patients.

RESUMO

OBJECTIVE: The objective of this study was to investigate the influence of blood pressure on the severity and functional recovery of patients with acute cervical spinal cord injury (SCI) without fracture and dislocation. METHODS: A retrospective case control study analyzed the data of 40 patients admitted to our orthopedics department (Beijing Tiantan Hospital, Capital Medical University) from January 2013 to February 2021. They were diagnosed as acute cervical SCI without fracture and dislocation. Gender, age, height, weight, history of hypertension, postinjury American Spinal Injury Association grade, postinjury modified Japanese Orthopaedic Association (mJOA) score, postoperative mJOA score, 1-year follow-up mJOA score, preoperative mean arterial pressure (MAP), intramedullary T2 hyperintensity, and hyponatremia were collected. The patients were divided into groups and subgroups based on their history of hypertension and preoperative MAP. The effects of history of hypertension and preoperative MAP on the incidence of T2 hyperintensity, hyponatremia, the improvement rate of the postoperative mJOA and 1-year follow-up mJOA scores were analyzed. RESULTS: Patients with history of hypertension had a lower incidence of intramedullary T2 hyperintensity than patients without history of hypertension (P < 0.05). Patients with history of hypertension and patients with a higher preoperative MAP had better neurological recovery at 1 year of follow-up (P < 0.05). CONCLUSIONS: Blood pressure has great influence on acute cervical SCI without fracture and dislocation. Maintaining a higher preoperative MAP is advantageous for better recovery after SCI. Attention should be paid to the dynamic management of blood pressure to avoid the adverse effects of hypotension after SCI.

RESUMO

STUDY DESIGN: Consensus process. OBJECTIVES: To provide a reference for the Zone(s) of Partial Preservation (ZPP) in the 2019 International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) and analyze the initial impact of applicability of the revised ZPPs. Revisions include the use of ZPPs in selected incomplete injuries (in addition to prior use in sensorimotor complete injuries). Specifically, the revised motor ZPPs are applicable bilaterally in injuries with absent voluntary anal contraction (VAC) and the revised sensory ZPP for a given side is applicable if deep anal pressure (DAP), light touch and pin prick sensation in S4-5 are absent on that side. SETTING: Committee with 16 ISNCSCI experts and datasets from the European Multicenter Study about Spinal Cord Injury (EMSCI). METHODS: Occurrence frequencies of applicable ZPPs were determined in an EMSCI cohort consisting of two ISNCSCI examinations from 665 individuals with traumatic SCI. RESULTS: Motor ZPPs were derived in 35.2% of all datasets of incomplete injuries, while sensory ZPPs are much less frequent (1.0%). Motor ZPPs are applicable in all American Spinal Injury Association Impairment Scale (AIS) B datasets (mean ZPP length: 0.9 ± 1.0 segments), in 55.4% of all AIS C datasets (ZPP length: 11.8 ± 8.2 segments) and in 9.9% of the AIS D datasets (ZPP length: 15.4 ± 7.9 segments). CONCLUSIONS: The revised ZPP allows for determining motor ZPPs in approximately 1/3 of all incomplete injuries. The broadened applicability enables the use of ZPPs beyond complete injuries for complementary description of residual functions in more individuals. SPONSORSHIP: N/A.

RESUMO

BACKGROUND: The Short-Form Qualiveen (SF-Qualiveen) questionnaire assesses the effect of bladder and urinary symptoms on patients' quality of life (QoL) with urological impairment caused by neurological diseases. There is no validated SF-Qualiveen questionnaire in Arabic, so this study aims to provide a translated and validated version of the SF-Qualiveen questionnaire among Arabic patients experiencing spinal cord injury (SCI). METHODS: Psychometric features such as content and construct validity, test-retest reliability, and internal consistency were analyzed. Construct validity was evaluated by contrasting the SF-Qualiveen with the Neurogenic Bladder Symptom Score Short-Form (NBSS-SF) questionnaire. Internal consistency was measured using Cronbach's alpha, whereas the intraclass correlation coefficient (ICC) was employed to assess the test-retest reliability. Factorial validity was established by principal component analysis (PCA). RESULTS: The internal consistency of the total SF-Qualiveen and the domains "Bother with limitations," "Fear," "Feeling," and "Frequency of limitations" showed good internal consistency (Cronbach's alpha of > 0.7). ICC was 0.90 for the total score, 0.83 for the bother with limitations, 0.80 for fears, 0.84 for feeling, and 0.81 for frequency of limitations. The correlation analysis revealed a positive association between the total scores on the NBSS-SF and the domains of the SF-Qualiveen, comprising bother with limitations (r = 0.53, p = 0.02), fears (r = 0.44, p = 0.03), feelings (r = 0.49, p = 0.04), and frequency of limitations (r = 0.46, p = 0.02). The best-fit four-factor model for confirming overall item communalities ranged from 0.552 to 0.814, which indicates moderate to high communalities, and confirms the homogeneity of the SF-Qualiveen using PCA. CONCLUSIONS: The findings of this validation study revealed that the SF-Qualiveen is a reliable and valid instrument appropriate for Arabic-speaking patients with SCI in both research and clinical practices.

RESUMO

OBJECTIVES: The goal of this study is to implement machine learning (ML) algorithms to predict mortality, non-home discharge, prolonged length of stay (LOS), prolonged length of intensive care unit stay (ICU-LOS), and major complications in patients diagnosed with thoracolumbar spinal cord injury, while creating a publicly accessible online tool. METHODS: The American College of Surgeons Trauma Quality Program database was used to identify patients with thoracolumbar spinal cord injury. Feature selection was performed with the Least Absolute Shrinkage and Selection Operator algorithm. Five ML algorithms, including TabPFN, TabNet, XGBoost, LightGBM, and Random Forest, were used along with the Optuna optimization library for hyperparameter tuning. RESULTS: A total of 147,819 patients were included in the analysis. For each outcome, we determined the best model for deployment in our web application based on the area under the receiver operating characteristic (AUROC) values. The top performing algorithms were as follows: LightGBM for mortality with an AUROC of 0.885, TabPFN for non-home discharge with an AUROC of 0.801, LightGBM for prolonged LOS with an AUROC of 0.673, Random Forest for prolonged ICU-LOS with an AUROC of 0.664, and LightGBM for major complications with an AUROC of 0.73. CONCLUSIONS: ML models demonstrate good predictive ability for in-hospital mortality and non-home discharge, fair predictive ability for major complications and prolonged ICU-LOS, but poor predictive ability for prolonged LOS. We have developed a web application that allows these models to be accessed.

RESUMO

INTRODUCTION: Spinal cord injury (SCI) is one of the most dreaded complications after spinal cord stimulation (SCS) implantation surgery. As a result, intraoperative neurophysiological monitoring (IONM) has been proposed to avoid accidental damage to nervous structures under anesthesia and confirm positioning for optimal stimulation. Our study uses a large administrative claims database to determine the 30-day risk of SCI after SCS implantation. METHODS: This retrospective cohort study used the IBM MarketScan Commercial and Medicare Supplemental Databases from 2016 to 2019. Adult patients undergoing SCS surgical procedures with at least 90 days of follow-up, IONM use, the type of sedation used during the procedure, and subsequent SCI were identified using administrative codes. In addition, logistic regression was used to examine the relationship between various risk factors and subsequent SCI. RESULTS: A total of 9676 patients underwent SCS surgery (64.7% percutaneous implants) during the study period. Nine hundred and forty-four (9.75%) patients underwent SCS implantation with IONM. Conscious sedation, Monitored Anesthesia Care anesthesia, and general anesthesia were used in patients with 0.9%, 60.2%, and 28.6%, respectively. Eighty-one (0.8%) patients developed SCI within 30 days after SCS implant surgery. The SCI rate was higher in the group that underwent IONM (2% vs 0.7%, p value <0.001) during the implantation procedure, reflecting the underlying risk. After adjustment for other factors, the OR of SCI is 2.39 (95% CI: 1.33 to 4.14, p value=0.002) times higher for those with IONM than those without IONM. CONCLUSIONS: Increased SCI risk among patients with IONM likely reflects higher baseline risk, and further research is needed for risk mitigation.

RESUMO

STUDY DESIGN: Observational, comparative, and transversal study. OBJECTIVE: To identify the cut-off points in the Trunk Control Test (TCT) for individuals with Spinal Cord Injury (SCI) to determine the ability to perform independently the different activities of daily living (ADL) according to the Spinal Cord Independence Measure-III (SCIM-III). SETTING: National Institute of Rehabilitation, Mexico City. METHODS: Individuals with SCI of any neurologic level and severity according to ISNCSCI, in sub-acute and chronic phases were included. Receiver Operating Characteristic (ROC) curves were made to identify the cut-off points on the TCT that discriminate the individuals that can independently perform each of the ADL described in the SCIM-III. RESULTS: A total of 604 participants were evaluated, 70.7% male; mean age of 34 (± 14) years; time since injury was 134 ± 360 days; predominating motor complete injury (50.1%). It was demonstrated through ROC curves, that there are different cut-off points in the TCT that are sensitive and specific to discriminate individuals that can independently perform the majority of the items of the SCIM-III of those who perform it with assistance. Domains that do not depend on an adequate trunk control (respiration and sphincter management) had poor areas under the curve, with low sensitivity and specificity. CONCLUSIONS: The application of the TCT in individuals with SCI allows to discriminate between individuals who perform the different ADL independently of those who do not, at this subject institute. These results can guide the management of individuals with SCI, helping to establish short term goals.

RESUMO

Perinatal spinal cord injury is a relatively uncommon, but a frequently misdiagnosed disorder. Improvements in obstetric care have certainly led to a decrease in the incidence of birth related spinal cord trauma but unfortunately the incidence of hypoxic-ischemic encephalopathy is still very high. The exact incidence of spinal cord trauma is difficult to determine because the spinal cord is not routinely examined in far and few neonatal autopsies done in India. Here, authors present a neonate who received treatment for birth asphyxia and then had extubation failure which made the clock tick towards cervical cord injury. This baby had a hemorrhagic contusion of cervical spinal cord.
