The role of payment sources in the continuation of rehabilitation therapy in tertiary hospitals for patients with traumatic spinal cord injury: a study in Southwest China. Ann Med 2024; 56:2333890. [PMID: 38557236 PMCID: PMC10986431 DOI: 10.1080/07853890.2024.2333890] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2023] [Accepted: 03/06/2024] [Indexed: 04/04/2024] Open
Abstract
Medical security support for rehabilitation therapy in China is different from that in other countries. We investigated whether the discharge plan to continue rehabilitation therapy in tertiary hospitals for patients after traumatic spinal cord injury (TSCI) was influenced by payment sources or other conditions. This was a cross-sectional, observational study. Information was collected on the general condition, caregiver, types of payment sources for continued rehabilitation, American Spinal Injury Association Impairment Scale (AIS) scores, and discharge plans. In total, 135 patients with TSCI (107 male, mean age 41.00 ± 13.73 years, mean spinal cord injury duration 238.43 ± 345.54 days) were enrolled. Medical insurance (43%) and out-of-pocket payments (27.4%) were the primary payment sources. Although most patients were beyond the acute phase, 40% continued rehabilitation therapy at other tertiary hospitals. The caregiver, payment sources, injury level, AIS level, and complete urinary tract infection (UTI) were different due to discharge plans (p > .05). Patients seemingly consider a higher AIS level and co-UTI as the requirement for tertiary hospital therapy. In non-medical insurance payment source patients, the discharge plan also differed due to the AIS level and co-UTI (p > .05). However, in medical insurance patients, the discharge plan differed only in terms of TSCI duration (p > .05). The restricted duration of medical coverage restricted the continuation of rehabilitation therapy and influenced the discharge plan of most patients with TSCI.

Abstract
Spinal cord injury (SCI) is a central nervous system injury that leads to neurological dysfunction or paralysis, which seriously affects patients' quality of life and causes a heavy social and economic burden. The pathological mechanism of SCI has not been fully revealed, resulting in unsatisfactory clinical treatment. Therefore, more research is urgently needed to reveal its precise pathological mechanism. Numerous studies have shown that inflammation is closely related to various pathological processes in SCI. Inflammatory response is an important pathological process leading to secondary injury, and sustained inflammatory response can exacerbate the injury and hinder the recovery of neurological function after injury. Epigenetic modification is considered to be an important regulatory mechanism in the pathological process of many diseases. Epigenetic modification mainly affects the function and characteristics of genes through the reversibility of mechanisms such as DNA methylation, histone modification, and regulation of non-coding RNA, thus having a significant impact on the pathological process of diseases and the survival state of the body. Recently, the role of epigenetic modification in the inflammatory response of SCI has gradually entered the field of view of researchers, and epigenetic modification may be a potential means to treat SCI. In this paper, we review the effects and mechanisms of different types of epigenetic modifications (including histone modifications, DNA methylation, and non-coding RNAs) on post-SCI inflammation and their potential therapeutic effects on inflammation to improve our understanding of the secondary SCI stage. This review aims to help identify new markers, signaling pathways and targeted drugs, and provide theoretical basis and new strategies for the diagnosis and treatment of SCI.

Abstract
Background Blunt trauma is a physical injury to a part of the body, mainly caused by road accidents, direct blows, attacks, sports injuries, and falls in elderly people. Spinal fractures are observed only in a small percentage of injured patients. Accordingly, the present study was conducted on collected data between 2018 and 2022 to determine the frequency of spinal fractures in blunt trauma in Iran while also considering the mechanism of injury as a secondary outcome of interest. Methods In this retrospective study, blunt trauma patients with spinal fractures, regardless of age were included by the census sampling method. Data were obtained from the National Trauma Registry of Iran. Means and standard deviations were used for continuous variables, and the chi-square test was used to assess the relationship between the variables. Results Among 25,986 cases of all-cause trauma patients, 1,167 cases (4.5%) of blunt trauma and spinal fracture were included in the study. Gender, the severity of injury, and the cause of trauma showed a significant difference among different age groups (p < 0.05). Significant differences were found in the injury mechanisms across various spine regions (p < 0.05). The majority of patients (68.2%) had lumbar spinal fractures. Road traffic collisions were the most common cause of spinal cord injuries, accounting for 58.3% of cases, followed by falls (36.1%). The injury severity score was higher in younger patients (under 18 years old), with a mean of 4.4 ± 3.5, and in patients with cervical injuries. The majority of injuries occurred in the lumbar area (68.2%), followed by the thoracic area. Furthermore, notable variations existed in Emergency Room (ER) stay duration, overall hospitalization, Intensive Care Unit (ICU) stay duration, and injury severity levels, all influenced by the spinal regions (p < 0.05). Distinctively, ICU stay durations and ER stay duration showed significant differences, particularly in relation to injuries in the lumbar and thoracic regions (p < 0.05). Conclusion According to the results of the present study, trauma is more severe, and cervical injuries are more common in young people, which is a critical finding that underscores the need for targeted interventions to mitigate the severity of trauma in this age group. Additionally, the majority of cervical injuries occurred in young people, which is a particularly concerning finding given the potential for long-term disability and impact on quality of life. Our findings suggest that strategies to reduce cervical injuries, such as speed control, seat belt use, and phone-free driving, are crucial interventions for mitigating the severity of trauma and promoting patient outcomes in young people.

Abstract
Spinal cord injury (SCI) is a serious, disabling injury to the central nervous system that can lead to motor, sensory, and autonomic dysfunction below the injury plane. SCI can be divided into primary injury and secondary injury according to its pathophysiological process. Primary injury is irreversible in most cases, while secondary injury is a dynamic regulatory process. Secondary injury involves a series of pathological events, such as ischemia, oxidative stress, inflammatory events, apoptotic pathways, and motor dysfunction. Among them, oxidative stress is an important pathological event of secondary injury. Oxidative stress causes a series of destructive events such as lipid peroxidation, DNA damage, inflammation, and cell death, which further worsens the microenvironment of the injured site and leads to neurological dysfunction. The nuclear factor erythrocyte 2-associated factor 2 (Nrf2) is considered to be a key pathway of antioxidative stress and is closely related to the pathological process of SCI. Activation of this pathway can effectively inhibit the oxidative stress process and promote the recovery of nerve function after SCI. Therefore, the Nrf2 pathway may be a potential therapeutic target for SCI. This review deeply analyzed the generation of oxidative stress in SCI, the role and mechanism of Nrf2 as the main regulator of antioxidant stress in SCI, and the influence of cross-talk between Nrf2 and related pathways that may be involved in the pathological regulation of SCI on oxidative stress, and summarized the drugs and other treatment methods based on Nrf2 pathway regulation. The objective of this paper is to provide evidence for the role of Nrf2 activation in SCI and to highlight the important role of Nrf2 in alleviating SCI by elucidating the mechanism, so as to provide a theoretical basis for targeting Nrf2 pathway as a therapy for SCI.

Abstract
OBJECTIVE Polypharmacy in spinal cord injury (SCI) is common and predisposes patients to increased risk of adverse events. Evaluation of long-term health consequences and economic burden of polypharmacy in patients with SCI is explored. DESIGN Retrospective cohort. METHODS The IBM Marketscan Research Databases claims-based dataset was queried to search for adult patients with SCI with a 2-year follow-up. PARTICIPANTS Two matched cohorts were analyzed: those with and without polypharmacy, analyzing index hospitalization, readmissions, payments, and health outcomes. RESULTS A total of 11 569 individuals with SCI were included, of which 7235 (63%) were in the polypharmacy group who took a median of 11 separate drugs over two years. Opioid analgesics were the most common medication, present in 57% of patients with SCI meeting the criteria of polypharmacy, followed by antidepressant medications (46%) and muscle relaxants (40%). Risk of pneumonia was increased for the polypharmacy group (58%) compared to the non-polypharmacy group (45%), as were urinary tract infection (79% versus 63%), wound infection (30% versus 21%), depression (76% versus 57%), and adverse drug events (24% versus 15%) at 2 years. Combined median healthcare payments were higher in polypharmacy at 2 years ($44 333 vs. $10 937, P < .0001). CONCLUSION Majority of individuals with SCI met the criteria for polypharmacy with nearly 60% of those prescribed opioids and taking drugs from high-risk side effect profiles. Polypharmacy in SCI was associated with a greater risk of pneumonia, depression, urinary tract infections, adverse drug events, and emergency room visits over two years with four times higher overall healthcare payments at 1-year post-injury.

Spinal cord injury (SCI) is a serious disabling central nervous system injury that can lead to motor, sensory, and autonomic dysfunction below the injury level. SCI can be divided into primary injury and secondary injury according to pathological process. Primary injury is mostly irreversible, while secondary injury is a dynamic regulatory process. Apoptosis is an important pathological event of secondary injury and has a significant effect on the recovery of nerve function after SCI. Nerve cell death can further aggravate the microenvironment of the injured site, leading to neurological dysfunction and thus affect the clinical outcome of patients. Therefore, apoptosis plays a crucial role in the pathological progression of secondary SCI, while inhibiting apoptosis may be a promising therapeutic strategy for SCI. This review will summarize and explore the factors that lead to cell death after SCI, the influence of cross talk between signaling pathways and pathways involved in apoptosis and discuss the influence of apoptosis on SCI, and the therapeutic significance of targeting apoptosis on SCI. This review helps us to understand the role of apoptosis in secondary SCI and provides a theoretical basis for the treatment of SCI based on apoptosis.

Abstract
OBJECTIVE We aimed to examine the effectiveness of noninvasive brain stimulation on motor dysfunction after incomplete spinal cord injury. METHODS The PubMed, Embase, and Cochrane Library were searched from the inception dates to April 30, 2022. Randomized controlled trials comparing the effects of noninvasive brain stimulation and sham stimulation on motor dysfunction in patients with incomplete spinal cord injury were included. Two reviewers performed the data extraction and assessed study quality using Cochrane Collaboration's Tool. The primary outcomes involved upper limb function, lower limb function, spasticity, and activities of daily living. They were analyzed using meta-analysis method and the results were reported as standardized mean difference with 95% confidence interval. RESULTS Fourteen studies involving 225 patients were included. Noninvasive brain stimulation reduced spasticity at the end of intervention (standardized mean difference = -0.68, 95% confidence interval = -1.32 to -0.03, P = 0.04) and 1-wk follow-up (standardized mean difference = -0.82, 95% confidence interval = -1.48 to -0.16, P = 0.02), but no beneficial effect at 1-mo follow-up (standardized mean difference = -0.32, 95% confidence interval = -1.06 to 0.42, P = 0.39). In addition, noninvasive brain stimulation also increased lower limb muscle strength at 1-mo follow-up (standardized mean difference = 0.69, 95% confidence interval = 0.11 to 1.28, P = 0.02). Other main outcomes were similar between groups. CONCLUSIONS Noninvasive brain stimulation can reduce spasticity, and the favorable effect can sustain for 1 wk after intervention. In addition, noninvasive brain stimulation can increase lower limb muscle strength at 1-mo follow-up.

Abstract
The pathology of spinal cord injury (SCI), including primary and secondary injuries, primarily involves hemorrhage, ischemia, edema, and inflammatory responses. Cell transplantation has been the most promising treatment for SCI in recent years; however, its specific molecular mechanism remains unclear. In this study, bioinformatics analysis verified by experiment was used to elucidate the hub genes associated with SCI and to discover the underlying molecular mechanisms of cell intervention. GSE46988 data were downloaded from the Gene Expression Omnibus dataset. In our study, differentially expressed genes (DEGs) were reanalyzed using the "R" software (R v4.2.1). Functional enrichment and protein-protein interaction network analyses were performed, and key modules and hub genes were identified. Network construction was performed for the hub genes and their associated miRNAs. Finally, a semi-quantitative analysis of hub genes and pathways was performed using quantitative real-time polymerase chain reaction. In total, 718 DEGs were identified, mainly enriched in immune and inflammation-related functions. We found that Cd4, Tp53, Rac2, and Akt3 differed between vehicle and transplanted groups, suggesting that these genes may play an essential role in the transplantation of olfactory ensheathing cells, while a toll-like receptor signaling pathway was significantly enriched in Gene set enrichment analysis, and then, the differences were statistically significant by experimentally verifying the expression of their associated molecules (Tlr4, Nf-κb, Ikkβ, Cxcl2, and Tnf-α). In addition, we searched for upstream regulatory molecules of these four central genes and constructed a regulatory network. This study is the first to construct a regulatory network for olfactory ensheathing cell transplantation in treating SCI, providing a new idea for SCI cell therapy.

Abstract
Spinal cord injury (SCI) is a type of central nervous system trauma that can lead to severe nerve injury. Inflammatory reaction after injury is an important pathological process leading to secondary injury. Long-term stimulation of inflammation can further deteriorate the microenvironment of the injured site, leading to the deterioration of neural function. Understanding the signaling pathways that regulate responses after SCI, especially inflammatory responses, is critical for the development of new therapeutic targets and approaches. Nuclear transfer factor-κB (NF-κB) has long been recognized as a key factor in regulating inflammatory responses. The NF-κB pathway is closely related to the pathological process of SCI. Inhibition of this pathway can improve the inflammatory microenvironment and promote the recovery of neural function after SCI. Therefore, the NF-κB pathway may be a potential therapeutic target for SCI. This article reviews the mechanism of inflammatory response after SCI and the characteristics of NF-κB pathway, emphasizing the effect of inhibiting NF-κB on the inflammatory response of SCI to provide a theoretical basis for the biological treatment of SCI.

Abstract
BACKGROUND Assessing spinal injuries in patients with traumatic head injuries is crucial due to their potential to alter functionality and increase mortality rates. This single-center retrospective study was conducted to understand the prevalence and characteristics of concurrent spinal injuries in adults with traumatic head injury from April 2015 to April 2022. MATERIAL AND METHODS The study incorporated demographic, clinical, traumatological, and hemodynamic data from 1,501 adult patients presenting with traumatic head injuries. Spinal injuries were identified through symptoms, physical signs, and radiological findings. RESULTS During the study period, 179 patients (12%) were reported with associated spinal injuries. These patients were predominantly male (p=0.0012), aged 65 years or above (p=0.0452), had thoracic injuries (p=0.0004), and arrived at the emergency department more than three hours post-trauma (p=0.0004). Most injuries were caused by motor vehicle accidents (p=0.0412) or falls from heights greater than 3 meters (p=0.0481). In addition, these patients had higher Abbreviated Injury Scale scores (≥2, p=0.0391), Eppendorf-Cologne Scale scores (≥2, p=0.0412), and lower systolic and diastolic blood pressure readings (p=0.0481, p=0.0412) along with lower heart rates (p=0.0482). However, no correlation was found between systolic and diastolic pressures and age among patients with spinal injuries. CONCLUSIONS This study reveals that the prevalence and severity of spinal injuries in patients with traumatic head injuries are influenced not only by demographic and clinical parameters, but also by the degree and extent of head trauma.

Incidence, prevalence and disability of spinal cord injury in China from 1990 to 2019: a systematic analysis of the Global Burden of Disease Study 2019. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2023; 32:590-600. [PMID: 36350373 DOI: 10.1007/s00586-022-07441-2] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Revised: 09/21/2022] [Accepted: 10/27/2022] [Indexed: 11/11/2022]
Abstract
PURPOSE We aimed to estimate the incidence, prevalence and years lived with disability (YLDs) of spinal cord injury (SCI) in China in 2019 and temporal trends from 1990 to 2019. METHODS The Global Burden of Disease Study 2019 was used to obtain data. Outcome measures included age-standardized incidence rate (ASIR), prevalence rate (ASPR) and YLDs rate (ASYR). A Bayesian meta-regression tool, DisMod-MR 2.1, was used to produce the estimates of each value after adjustments. RESULTS In 2019, there were 234.19 [95% uncertainty interval (UI) 171.84-312.87] thousand incident cases of SCI in China, with an ASIR of 13.87 (95% UI 10.15-18.66) per 100,000. ASIR and ASYR increased by 40.81% (95% UI 32.92-49.14%) and 11.44% (95% UI 5.16-17.29%) compared with 1990, individually. Males had higher ASIR and ASYR in each year from 1990 to 2019, but the incidence and YLDs rates of females exceeded males after 70 years old. Incidence and YLDs rates both ascended with age. SCI at neck level had slightly higher incidence rate but much higher YLDs rate than that below neck level. The average incidence age increased from 38.97 in 1990 to 54.59 in 2019. Falls were the leading cause of SCI. CONCLUSION The incidence and burden of SCI in China increased significantly during the past three decades. The age structure of SCI patients showed a shift from the young to the elderly as population aging. Urgent efforts are needed to relieve the health pressure from SCI.

Abstract
Background Traumatic spinal cord injury (TSCI) is a type of highly disabling central nervous system trauma. In this study, we investigated the epidemiological characteristics of 1,806 TSCI patients and compared the characteristics of patients with traumatic cervical spinal cord injury (TCSCI) caused by cervical fracture/dislocation and disc herniation/bulging. Methods We retrospectively reviewed the hospital records of 1,806 TSCI patients. The detailed information included gender, marital status, occupation, age, neurological level of injury, etiology, American Spinal Injury Association (ASIA) grade, combined injuries, complications, treatment, the interval between admission and surgery, intubation/tracheostomy requirement, and the length of hospital stay. Results Cervical spinal cord injury (CSCI) was the most common injury. Compared to non-CSCI cases, patients with TCSCI were older, and more likely to suffer from tetraplegia and require intubation/tracheostomy, but had fewer other injuries or complications and a shorter length of hospital stay. Compared to patients with cervical fracture/dislocation, those with TCSCI caused by disc herniation/bulging were older and more likely to suffer from paraplegia, but required intubation/tracheostomy less frequently, exhibited fewer other injuries and complications, and required shorter hospitalization. Conclusions Men, married individuals, manual laborers, and individuals aged 31-75 years had the highest risk of TSCI. Patients with TCSCI tended to have a shorter length of hospital stay than patients with non-CSCI. More attention should be paid to the other injuries and complications of non-CSCI patients, which may increase the length of hospital stay and delay rehabilitation. Compared to patients with cervical disc herniation, the patients with fracture/dislocation tended to be younger, but prognosis was severely compromised by tetraplegia, a greater need for intubation/tracheostomy, additional injuries, and complications.

Abstract
Spinal cord injury (SCI) is a global problem that brings a heavy burden to both patients and society. Recent investigations indicated degenerative disease is taking an increasing part in SCI with the growth of the aging population. However, little insight has been gained about the effect of cervical degenerative disease on the spinal cord during dynamic activities. In this work, a dynamic fluid-structure interaction model was developed and validated to investigate the effect of anterior and posterior encroachment caused by degenerative disease on the spinal cord during normal extension and flexion. Maximum von-Mises stress and maximum principal strain were observed at the end of extension and flexion. The abnormal stress distribution caused by degenerative factors was concentrated in the descending tracts of the spinal cord. Our finding indicates that the excessive motion of the cervical spine could potentially exacerbate spinal cord injury and enlarge injury areas. Stress and strain remained low compared to extension during moderate flexion. This suggests that patients with cervical degenerative disease should avoid frequent or excessive flexion and extension which could result in motor function impairment, whereas moderate flexion is safe. Besides, encroachment caused by degenerative factors that are not significant in static imaging could also cause cord compression during normal activities.

Abstract
BACKGROUND Caregivers of individuals with spinal cord injury encounter high levels of physical, psychosocial, and financial burden by providing lifelong assistance. In the present study, we aimed to assess the overall burden score of caregivers in spinal cord injury by pooling different standard scores together as a review. METHOD Search on databases of PubMed/Medline, Web of Science and Scopus was conducted using PRISMA guidelines. Studies that assessed the burden of care using the caregiver burden inventories of CBI (caregiver burden inventory), CBS (caregiver burden scale), CG (caregiver), CSI (Caregiver Strain Index), and short- and long-form Zarit questionnaires were included in our study. The results were analyzed using the meta-analysis method and a random effect pooled estimator. All analyses were performed using STATA SE software version 14. RESULT A total of 23 articles out of 399 retrieved studies were added to this review study. The overall score of caregiver burden in individuals with SCI was calculated 48.68 (95% CI 42.574-54.788). The I2 heterogeneity was 11.7%, suggesting a low level of heterogeneity among the included studies. There was no systematic difference between various questionnaires added to meta-analysis (P = 0.526). In addition, the caregiver burden did not differ in less and highly developed countries (P = 0.405). CONCLUSION Since SCI places a considerable burden on caregivers, scoring the burden of care can help policymakers plan for essential interventions and allocate more facilities for these patients and their caregivers.

Abstract
Background and PurposeThe epidemiological characteristics of traumatic spinal cord injury (TSCI) in China are unclear. Thus, we aimed to study prevalence, incidence, and external causes of TSCI in China nationwide.MethodsIn 2013, we conducted a nationally representative, door-to-door epidemiological survey on TSCI in China using a complex, multistage, probability sampling design.ResultsIn China, the point prevalence of TSCI standardized to the China census population 2010 was 569.7 (95% CI: 514.2–630.4) per 1,000,000 in the population, 753.6 (95% CI: 663.3–854.3) per 1,000,000 among men, and 387.7 (95% CI: 324.8–461.1) per 1,000,000 among women. The incidence of TSCI standardized to the China census population 2010 was 49.8 (95% CI: 34.4–70.7) per 1,000,000 per year in the population, 63.2 (95% CI: 38.9–98.5) per 1,000,000 among men, and 36.9 (95% CI: 19.5–65.9) per 1,000,000 among women. Among the 415 TSCI events in 394 prevalent cases, the top three injury causes were falls (55.2%), motor vehicle collisions (MVCs) (26.5%), and strike injuries (10.1%), while other injury causes including gunshot and explosion accounted for 8.2%. Among the 394 prevalent cases, the mean age of patients at the time of injury was 43.7 ± 17.1 years; the male-to-female ratio was 1.86:1.ConclusionIt is estimated that there are 759,302 prevalent patients with TSCI in total and 66,374 new TSCI cases annually in China. Falls and MVCs are still 2 major external causes for TSCI in China.

Epidemiological profile of 338 traumatic spinal cord injury cases in Shandong province, China. Spinal Cord 2021; 60:635-640. [PMID: 34588624 DOI: 10.1038/s41393-021-00709-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2021] [Revised: 09/10/2021] [Accepted: 09/13/2021] [Indexed: 11/08/2022]
Abstract
STUDY DESIGN Hospital-based retrospective review. OBJECTIVE To describe the epidemiological characteristics of traumatic spinal cord injury (TSCI) in Liaocheng, China. SETTING Liaocheng People's Hospital. METHODS Medical records of 338 persons with TSCI admitted to Liaocheng People's Hospital from 2013 to 2017 were reviewed. The detailed information included gender, age, marital status, occupation, time, etiology, level of injury, ASIA grade, spinal stenosis, concomitant injury, treatment, length of stay. RESULTS Over this period, the mean age (SD) of persons with TSCI was 50.1 (14.1) years, and the male/female ratio was 3.1:1. 96.4% of all were married. The leading cause was fall, followed by motor vehicle accident (MVA). The most common level of injury was the cervical cord. ASIA grade D and A injuries were the most common, accounting for 48.5 and 29.3% respectively. Among the concomitant injuries, spinal fractures were the most common. Within 24 h, 91.1% of individuals with TSCI arrived hospital, 63.3% of all accepted surgery. CONCLUSION The results showed that fall and MVA were the two main causes, so we should focused on preventing fall and reducing MVA. Cervical spinal stenosis can increase the risk of TSCI, so education should be provided to this population to raise their risk awareness. In addition, timely treatment was critical for TSCI, but the data showed that rescue process was not standard, so it was necessary for medical staff to popularize professional knowledge.
