The challenge of spinal cord injury care in the developing world

Epigenetic modifications of inflammation in spinal cord injury

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.

Outcomes 10-years after traumatic spinal cord injury in Botswana - a long-term follow-up study

STUDY DESIGN

Prospective follow-up study.

OBJECTIVES

To describe outcomes, survival, and attendance to routine follow-up visits 10 years post-SCI.

SETTING

The national SCI-rehabilitation center in Botswana.

METHODS

All persons who were admitted with traumatic SCI during a 2-year period, 2011-2013, and survived up to 2 years post-injury were included. Data were collected from the medical records from the follow-up assessment closest to 10 years post-SCI and included demographic and clinical characteristics, functional outcomes, and secondary complications. Data regarding mortalities were received from relatives. Statistical comparisons were made, when possible, between those who attend follow-up assessment and those who did not, and between those who survived up to 10 years post-SCI and those who died.

RESULTS

The follow-up rate was 76% (19/25) of known survivors. No statistically significant factors were found to affect the follow-up rate. Secondary complications rates were for pressure ulcers and urinary tract infections 21%. Self-catheterisation and suprapubic catheter were the preferred methods to manage neurogenic bladder dysfunction. Ten persons (26%) had deceased since 2nd follow-up assessment. The causes of death were probably SCI-related in more than half of the cases.

CONCLUSIONS

This was a follow-up study at year 10 after acute TSCI in Botswana conducted at the national SCI-rehabilitation center. The study supports previous reports regarding the importance of that having specialized SCI units and the need of structured follow-ups, a responsible person in charge of scheduling, and updated patient registers. We found high follow-up rate, low rates of complications and of patients being lost to follow-up.

Recent advances on signaling pathways and their inhibitors in spinal cord injury

Spinal cord injury (SCI) is a serious and disabling central nervous system injury. Its complex pathological mechanism can lead to sensory and motor dysfunction. It has been reported that signaling pathway plays a key role in the pathological process and neuronal recovery mechanism of SCI. Such as PI3K/Akt, MAPK, NF-κB, and Wnt/β-catenin signaling pathways. According to reports, various stimuli and cytokines activate these signaling pathways related to SCI pathology, thereby participating in the regulation of pathological processes such as inflammation response, cell apoptosis, oxidative stress, and glial scar formation after injury. Activation or inhibition of relevant pathways can delay inflammatory response, reduce neuronal apoptosis, prevent glial scar formation, improve the microenvironment after SCI, and promote neural function recovery. Based on the role of signaling pathways in SCI, they may be potential targets for the treatment of SCI. Therefore, understanding the signaling pathway and its inhibitors may be beneficial to the development of SCI therapeutic targets and new drugs. This paper mainly summarizes the pathophysiological process of SCI, the signaling pathways involved in SCI pathogenesis, and the potential role of specific inhibitors/activators in its treatment. In addition, this review also discusses the deficiencies and defects of signaling pathways in SCI research. It is hoped that this study can provide reference for future research on signaling pathways in the pathogenesis of SCI and provide theoretical basis for SCI biotherapy.

Targeted Therapy of Spinal Cord Injury: Inhibition of Apoptosis Is a Promising Therapeutic Strategy

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.

Spinal cord injury etiology, severity, and care in East Asia: a cross-sectional analysis of the International Spinal Cord Society Database Project

STUDY DESIGN

Cross-sectional study.

OBJECTIVES

To evaluate etiologic factors associated with spinal cord injury (SCI) severity and to identify predictive factors of reduction in SCI severity in six countries.

SETTING

SCI centers in Bangladesh, India, Malaysia, Nepal, Sri Lanka, and Thailand.

METHODS

Data from centers collected between October 2015 and February 2021 were analyzed using descriptive statistics and logistic regression.

RESULTS

Among 2634 individuals, the leading cause of SCIs was falls (n = 1410, 54%); most occurred from ≥1 meter (n = 1078). Most single-level neurological injuries occurred in the thoracic region (n = 977, 39%). Greater than half of SCIs (n = 1423, 54%) were graded American Spinal Injury Association Impairment Scale (AIS) A. Thoracic SCIs accounted for 53% (n = 757) of all one-level AIS A SCIs. The percentage of thoracic SCIs graded AIS A (78%) was significantly higher than high cervical (52%), low cervical (48%), lumbar (24%), and sacral (31%) SCIs (p < 0.001). Regression analyses isolated predictive factors both of SCI severity and inpatient improvement. Four factors predicted severity: age, neurological level, etiology, and country of residence. Four factors predicted improvement: age, neurological level, AIS grade on intake, and country of residence.

CONCLUSIONS

Findings can be used by healthcare providers and public health agencies in these countries to inform the public of the risk of SCI due to falls. Future studies should examine the social and occupational milieux of falls. Country-to-country comparisons of prehospital and inpatient care are also justified. Fall prevention policies can encourage the use of safety equipment when performing tasks at heights ≥1 meter.

Challenges and strategies in the surgical management of traumatic spinal cord injuries in the Democratic Republic of the Congo

BACKGROUND

Significant progress has been made in the management of traumatic spinal cord injuries. However, deep disparities persist in developing countries. This work aims to describe the different challenges in the surgical management of traumatic spinal cord injuries at the Kinshasa University Teaching Hospital and some strategies implemented to overcome them.

METHODS

This is a cross-sectional study of 105 patients from January 2016 to June 2023. The variables of interest included: gender, age, cause, levels of lesion, hospital admission modalities, time to admission, time to surgery, AIS score at admission and on discharge, treatment, pre, peri- and post-operative complications and outcome.

RESULTS

We admitted 105 patients. Only 16 % of them were taken to hospital in an ambulance. The average admission time was 49.9 ± 81.79 days. Seventy-two patients (68.6 %) were operated. The average time to surgery was 62.43 ± 85.20 days. No patient was stabilized at the trauma site. Osteosynthesis was performed with appropriate implants in 63.2 % and with improvised elements in 26.8 %. Four patients were operated without an image intensifier. Short-segmental fixation was performed in 8 patients. Twenty-one patients developed pressure ulcers. At discharge, 24 patients recovered their neurological function. Neurological status remained stationary in 43 patients. Five patients died. Seventeen patients went to rehabilitation center. There was no significant difference between the improvised strategies implemented and conventional procedures on functional recovery upon discharge from hospital or rehabilitation centre (p-value : 0.838 and 0.468 respectively).

CONCLUSION

Our establishment faces many challenges in TSCI surgery: lack of pre-hospital emergency services and mutual health insurance, delay in admission, lack of surgical implants and image intensifier, the poverty of the population. Some strategies have been implemented to overcome some of them.

Current Practice of Acute Spinal Cord Injury Management: A Global Survey of Members from the AO Spine

STUDY DESIGN

Cross-sectional, international survey.

OBJECTIVES

To examine current international practices as well as knowledge, adoption, and barriers to guideline implementation for acute spinal cord injury (SCI) management.

METHODS

A survey was distributed to members of AO Spine. The questionnaire was structured to obtain demographic data and preferred acute SCI practices surrounding steroid use, hemodynamic management, and timing of surgical decompression.

RESULTS

593 members completed the survey including orthopaedic surgeons (54.3%), neurosurgeons (35.6%), and traumatologists (8.4%). Most (61.2%) respondents were from low and middle-income countries (LMICs). 53.6% of physicians used steroids for the treatment of acute SCIs. Respondents from LMICs were more likely to administer steroids than HICs (178 vs. 78; P < .001). 331 respondents (81.5%) answered that patients would receive mean arterial pressure (MAP) targeted treatment. In LMICs, SCI patients were less likely to be provided with MAP-targeted treatment (76.9%) as compared to HICs (89%; P < .05). The majority of respondents (87.8%) reported that patients would benefit from early decompression. Despite overwhelming evidence and surgeons' responses that would offer early surgery, 62.4% of respondents stated they encounter logistical barriers in their institutions. This was particularly evident in LMICs, where 57.9% of respondents indicated that early intervention was unlikely to be accomplished, while only 21.1% of respondents from HICs stated the same (P < .001).

CONCLUSION

This survey highlights challenges in the implementation of standardized global practices in the management of acute SCI. Future research efforts will need to refine SCI guidelines and address barriers to guideline implementation.

Interleukin-18 in chronic pain: Focus on pathogenic mechanisms and potential therapeutic targets

Chronic pain has been proven to be an independent disease, other than an accompanying symptom of certain diseases. Interleukin-18 (IL-18), a pro-inflammatory cytokine with pleiotropic biological effects, participates in immune modulation, inflammatory response, tumor growth, as well as the process of chronic pain. Compelling evidence suggests that IL-18 is upregulated in the occurrence of chronic pain. Antagonism or inhibition of IL-18 expression can alleviate the occurrence and development of chronic pain. And IL-18 is located in microglia, while IL-18R is mostly located in astrocytes in the spinal cord. This indicates that the interaction between microglia and astrocytes mediated by the IL-18/IL-18R axis is involved in the occurrence of chronic pain. In this review, we described the role and mechanism of IL-18 in different types of chronic pain. This review provides strong evidence that IL-18 is a potential therapeutic target in pain management.

Psychosocial reintegration post-traumatic spinal cord injury in Rwanda: An exploratory study

Background

Traumatic spinal cord injury (TSCI) survivors are confronted by both physical and psychosocial barriers when returning to their communities. Therefore, reintegration is an important aspect of their journey back into social life.

Objectives

To assess psychosocial reintegration after TSCI in Rwanda.

Method

All community-dwelling adults who were registered in the previous epidemiological study were recruited and injury characteristics questionnaire and the Sydney Psychosocial Reintegration Scale version 2 (SPRS-2) were used to collect data through a telephone interview.

Results

The study traced 58 participants, 77.6% (n = 45) were male and 56.9% (n = 33) were categorised with paraplegia. Overall, the results show poor community reintegration. The SPRS-2 and domain mean (SD) scores were: overall SPRS-2 of 20.95 (11.56), occupational activity (OA) of 3.68 (4.31), interpersonal relationship (IR) of 7.11(4.31) and living skills (LS) of 7.43 (5.32). Gender significantly influenced overall SPRS-2 (p = 0.011) and two domains: OA (p = 0.005) and LS (p = 0.012). Level of injury was significantly associated with an OA domain score of SPRS-2 (p = 0.002). Gender explained 29% of the variance in the LS domain of SPRS-2, with males reporting better psychosocial reintegration.

Conclusion

Gender strongly predicted psychosocial reintegration following a TSCI, which is an indication of the role of social support.

Clinical Implications

Traumatic SCI rehabilitation should be holistic to help prepare the person to return to the community. There should be an assessment of an individual's readiness to return to the community before discharge from the hospital.

Acute spinal cord injury in Africa: exploring the long-term outcomes and future directions of acute spinal cord injury - short communication

Acute spinal cord injury (ASCI), a key factor behind serious sensory, motor, and autonomic dysfunctions, holds on as a fundamental cause of morbidity, psychological disturbances, and high socioeconomic burden. This study sheds light, particularly on the African countries where it is found that traumatic ASCI, mainly due to road traffic accidents, remains the leading cause, with 130 cases per million in this part of the world. Moreover, limited resources, with the lack of funds and equipment, as well as widespread poverty, restrict the availability of suitable diagnostic, management, and treatment options. The weight of the evidence suggests that there is an ultimate need for well-developed infrastructure embracing a multidisciplinary approach to rehabilitation in Africa. Furthermore, international collaborations, posing a significantly wide background for evidence-based information and resources, are indispensable for ASCI prospects and future studies among the African population. The purpose of this study is to fill a part of the persistent gap in the research era regarding the ASCI in Africa and direct future research toward investigating its different aspects as well as exploring its interventional needs.

Relational Empathy, Holistic Care, and Quality of Life in Persons With Spinal Cord Injuries: A Cross-sectional Study

INTRODUCTION

High-quality health systems are built on the concept of patient-centered approach, which includes holistic care and empathy. With time, this has progressively been recognized as a valuable paradigm for better health outcomes, particularly in chronic diseases.

OBJECTIVES

The study aims to determine the patients' perception during their consultation and to assess the relationship between Consultation and Relational Empathy measure with demographic/injury variables and quality of life.

METHODS

The present cross-sectional study was conducted among 226 individuals with spinal cord injuries. Data were collected via structured questionnaire, World Health Organization-Quality of life BREF, and Consultation and Relational Empathy measure. Independent t test is used to compare World Health Organization-Quality of life BREF domains with two groups of Consultation and Relational Empathy measure. Logistic regression was used to determine the significant factors of Consultation and Relational Empathy measure.

RESULTS

In the logistic regression analysis, it was observed that higher quality of life score has significantly higher odds of getting higher Consultation and Relational Empathy score with a remarkable odds ratio (odds ratio = 1.0264, 95% confidence interval = 1.0121-1.0261, P = 0.0001, 0.0472, 0.0001).

CONCLUSIONS

The quality of life of the present population is closely associated with greater perceptions of holistic care and empathy in the therapeutic patient-provider relationship. Lack of coordination, poor quality of life, and limited communication between patient and provider may arise when the latter focuses only on treating disease rather than treating a patient as a "whole person."

Traumatic Spinal Cord Injury among Patients Admitted to the Spine Unit in a Tertiary Care Centre

Introduction

Spinal cord injury usually results in disabling conditions. The incidence of spinal trauma is region-specific due to unique geography and demography. The epidemiology of spinal trauma changes with economic and social factors even in different periods. The aim of this study was to find out the prevalence of traumatic spinal cord injury among patients admitted to the Spine Unit in a tertiary care centre.

Methods

A descriptive cross-sectional study was done in a tertiary care centre among patients admitted to the Spine Unit from 1 January 2022 to 31 December 2022 after receiving ethical approval from the Institutional Review Committee. Demographic details, mode of injury, level of injuries, neurological grading at the time of admission using American Spinal Injury Association grading, management methods, and complication if any were recorded. A convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval.

Results

Out of 465 patients, the prevalence of traumatic spinal cord injury was 316 (67.95%) (63.72-72.20, 95% Confidence Interval). A total of 243 (76.89%) cases were due to falls. The mean age of patients was 43.13±16.55 years.

Conclusions

The prevalence of traumatic spinal cord injury patients was lower than the other studies done in similar settings.

Keywords

falls; prevalence; spinal cord injuries.

Quality of life of patients with traumatic spinal cord injuries: a cross-sectional study at a tertiary hospital in Uganda

Background

The study aimed to assess the perceived quality of life of patients with traumatic spinal cord injuries.

Methodology

This was a cross sectional study conducted in the Spine Unit of a tertiary hospital in Uganda. The study population comprised of patients with spinal cord injuries. Data were collected using the WHO Quality of Life Brief questionnaire and Functional Independence Measure tool.

Results

103 patients participated in the study, most were male (73.8%), and had a mean age of 37.7 years. Most participants were married (57.3%), unemployed (72.8%) and had no steady source of income (62.1%). Road traffic accidents accounted for most injuries (59.2%). The mean duration since injury was 20.5 months. Most participants (58.3%) had incomplete spinal cord injuries and 84.5% had complications. The perceived overall quality of life was poor in 87.4% of patients. Being employed (p= 0.02), the presence of complications (p= 0.03), and injury severity (p= 0.003) significantly affected quality of life. Functional independent measure scores were significantly better in individuals less severe injuries and those with lumbar level of injury with mean scores of 113.1±8.9 and 99.9±15.3 respectively.

Conclusion

The overall self-reported quality of life among patients with traumatic spinal cord injury was generally poor.

The Influence of Regional Differences on the Reliability of the AO Spine Sacral Injury Classification System

STUDY DESIGN

Global cross-sectional survey.

OBJECTIVE

To explore the influence of geographic region on the AO Spine Sacral Classification System.

METHODS

A total of 158 AO Spine and AO Trauma members from 6 AO world regions (Africa, Asia, Europe, Latin and South America, Middle East, and North America) participated in a live webinar to assess the reliability, reproducibility, and accuracy of classifying sacral fractures using the AO Spine Sacral Classification System. This evaluation was performed with 26 cases presented in randomized order on 2 occasions 3 weeks apart.

RESULTS

A total of 8320 case assessments were performed. All regions demonstrated excellent intraobserver reproducibility for fracture morphology. Respondents from Europe (k = .80) and North America (k = .86) achieved excellent reproducibility for fracture subtype while respondents from all other regions displayed substantial reproducibility. All regions demonstrated at minimum substantial interobserver reliability for fracture morphology and subtype. Each region demonstrated >90% accuracy in classifying fracture morphology and >80% accuracy in fracture subtype compared to the gold standard. Type C morphology (p2 = .0000) and A3 (p1 = .0280), B2 (p1 = .0015), C0 (p1 = .0085), and C2 (p1 =.0016, p2 =.0000) subtypes showed significant regional disparity in classification accuracy (p1 = Assessment 1, p2 = Assessment 2). Respondents from Asia (except in A3) and the combined group of North, Latin, and South America had accuracy percentages below the combined mean, whereas respondents from Europe consistently scored above the mean.

CONCLUSIONS

In a global validation study of the AO Spine Sacral Classification System, substantial reliability of both fracture morphology and subtype classification was found across all geographic regions.

Multi-Site Spinal Cord Transcutaneous Stimulation Facilitates Upper Limb Sensory and Motor Recovery in Severe Cervical Spinal Cord Injury: A Case Study

Individuals with cervical spinal cord injury (SCI) rank regaining arm and hand function as their top rehabilitation priority post-injury. Cervical spinal cord transcutaneous stimulation (scTS) combined with activity-based recovery training (ABRT) is known to effectively facilitate upper extremity sensorimotor recovery in individuals with residual arm and hand function post SCI. However, scTS effectiveness in facilitating upper extremity recovery in individuals with severe SCI with minimal to no sensory and motor preservation below injury level remains largely unknown. We herein introduced a multimodal neuro-rehabilitative approach involving scTS targeting systematically identified various spinal segments combined with ABRT. We hypothesized that multi-site scTS combined with ABRT will effectively neuromodulate the spinal networks, resulting in improved integration of ascending and descending neural information required for sensory and motor recovery in individuals with severe cervical SCI. To test the hypothesis, a 53-year-old male (C2, AIS A, 8 years post-injury) received 60 ABRT sessions combined with continuous multi-site scTS. Post-training assessments revealed improved activation of previously paralyzed upper extremity muscles and sensory improvements over the dorsal and volar aspects of the hand. Most likely, altered spinal cord excitability and improved muscle activation and sensations resulted in observed sensorimotor recovery. However, despite promising neurophysiological evidence pertaining to motor re-activation, we did not observe visually appreciable functional recovery on obtained upper extremity motor assessments.

International Spinal Cord Injury Community Survey: Socioeconomic and Healthcare Satisfaction in Spain

STUDY DESIGN

Survey study.

OBJECTIVES

People living with spinal cord injury (SCI) are major healthcare and rehabilitation services consumers and have unmet healthcare needs. This study aimed to describe the socioeconomic characteristics of people living with SCI in Spain and to determine the level of use and satisfaction with the public healthcare system.

METHODS

We conducted a survey (the Spanish version of the International Spinal Cord Injury Community Survey) consisting of 134 questions. We analyzed the age, sex, neurological classification of the injury on the American Spinal Injury Association Impairment Scale, time of injury, socio-occupational and socioeconomic status, and level of use and satisfaction with the public health system.

RESULTS

472 people responded to the survey [68.9% male; mean age 51.2 years (standard deviation: 13.9 years); 61.7% with paraplegia and 38.3% with tetraplegia]. 89.2% of those surveyed were unemployed and 77.1% received a disability pension. The number of medical visits was 2.3/year, and 19.8% of the patients required at least 1 hospital admission during the previous year. 94.7% of the people with SCI considered the health care received as good or very good.

CONCLUSIONS

Respondents with SCI in Spain considered they had good access to primary and specialized care and were satisfied with the healthcare system. Notably, we observed a high average of annual visits to medical professionals but a low rate of hospitalizations. Technical aids and state services related to disability should be the most important elements to be improved.

Clinical Profile and Predictors of Early Outcome in Patients with Traumatic Spinal Cord Injury in Jos, North-Central Nigeria

Background/Objectives

Spinal cord injury is a devastating condition and has been recognised so since antiquity with evolving pattern of presentation and outcome. This study aimed to review the clinical profile and determinants of early outcome in patients with traumatic spinal cord injury (TSCI) in Jos, Nigeria.

Materials and Methods

This retrospective cohort study, reviewed the health records of all patients with TSCI that were managed, based on the neurosurgical unit protocol for the management of TSCI in our institution from 2011 to 2021. Relevant data were retrieved into a preformed pro forma, analysis was done for determinants of outcome using SPSS and presented in tables and figure.

Results

A total of 296 patients, aged 20-39 years, with male to female ratio of 5.2:1 were studied. The median time from injury to presentation was 96 h, and the cervical spine was the most (139, 47.0%) affected region. Most of the patients (183, 61.8%) had complete injury (ASIA A) at presentation, the average, first week mean arterial blood pressure (MAP) of 89.98 ± 8.86. Mortality was 73 (24.7%) at 6 weeks post injury and complete TSCI, cervical spinal cord segment and the average "first week" MAP were, independent predictors of mortality. The admission ASIA impairment scale (AIS) and injury to presentation interval were predictive of AIS improvement at 6 weeks and length of hospital stay (LOHs).

Conclusions

We also found that AIS at admission, level of spinal cord affected and the average first week MAP were early predictors of mortality, while the injury to presentation interval and admission AIS, predicted improvement of AIS at 6 weeks. The LOHs was seen more in patients with severe AIS at admission and those who had delayed presentation.

Development of a comprehensive assessment tool to measure the quality of care for individuals with traumatic spinal cord injuries

OBJECTIVE

To develop a comprehensive assessment tool to evaluate the Quality of Care (QoC) in managing individuals with traumatic spinal cord injuries (TSCI).

METHOD

At first, the concepts of QoC for TSCI were identified by conducting a qualitative interview along with re-evaluation of the results of a published scoping review (conceptualization). After operationalization of indicators, they were valued by using the expert panel method. Afterward, the content validity index (CVI) and content validity ratio (CVR) were calculated and served as cut-offs for indicator selection. Then specific questions were developed for each indicator and classified into three categories: pre-hospital, in-hospital, and post-hospital. Data availability of the National Spinal Cord Injury Registry of Iran (NSCIR-IR) was subsequently used to design questions that represent indicators in an assessment tool format. The comprehensiveness of the tool was evaluated using a 4-item Likert scale by the expert panel.

RESULT

Twelve experts participated in conceptualization and 11 experts participated in operationalization phase. Overall, 94 concepts for QoC were identified from published scoping review (87 items) and qualitative interviews (7 items). The process of operationalization and indicator selection led to the development of 27 indicators with acceptable content validity. Finally, the assessment tool contained three pre-hospital, twelve in-hospital, nine post-hospital, and three mixed indicators. Ninety-one percent of experts evaluated the entire tool as comprehensive.

CONCLUSION

Our study presents a health-related QoC tool that contains a comprehensive set of indicators to assess the QoC for individuals with TSCI. However, this tool should be used in various situations to establish construct validity further.

A Comparison of Thoracolumbar Injury Classification in Spine Trauma Patients Among Neurosurgeons in East Africa Versus North America

Background In January 2021, we published findings evaluating the validity of thoracolumbar injury classification and biomechanical approach in the clinical outcome of operative and non-operative treatments. A notable result in our study was patients with unstable burst fractures received an Arbeitsgemeinschaft für Osteosynthesefragen System (AO) score that recommended conservative treatment compared to a Thoracolumbar Injury Classification and Severity Scale (TLICS) score that recommended surgical intervention. We designed a survey to determine reported differences in thoracolumbar injury classification, including the percentage of thoracolumbar spine fractures, type of classification system(s) used, use of classification system by board-certified neurosurgeons and neurosurgical residents, reliance on classification system to guide management, use of MRI in the evaluation of the posterior ligamentous complex, and readmission rate < 90 days at treating facilities. This study aims to determine which areas of neurosurgical practice in spine trauma patients differ among surgeons in North America and East Africa, including Ethiopia, Kenya, and Sudan. Multiple classification systems have been proposed to describe thoracolumbar spine injuries. We hypothesized that there would be marked variability in the classification systems used to evaluate thoracolumbar spine injury among neurosurgeons in North America and East Africa. Methods The survey consisted of seven questions and was sent to 440 neurosurgeons practicing on the continents of North America and East Africa. Results A total of 67 surgeons responded, 50 from North America and 17 from East Africa, including Ethiopia, Kenya, and Sudan. A significant percentage of African respondents reported a higher thoracolumbar spine fracture rate than respondents in North America (53% and 30%, respectively). Regarding the classification system used, 65% of surgeons in East Africa reported using TLICS, whereas 62% of surgeons in North America reported using Denis 3-column classification. For patients with spine trauma, surgeons in East Africa and North America reported a similar percentage of readmission <90 days (47% and 52%, respectively). Conclusion Our findings vary in spine trauma classification for American and East African patients and still highlight crucial areas for improvement due to patient load, education, and resource accessibility.

Time to Surgery in Spinal Trauma: A Meta-Analysis of the World's Literature Comparing High-Income Countries to Low-Middle Income Countries

OBJECTIVE

We conducted a systematic review and meta-analysis to: 1) compare time from traumatic spinal injury (TSI) to operating room (OR) in high-income countries (HICs) versus low-middle-income countries (LMICs), and 2) evaluate hospital length of stay (LOS) in HICs versus LMICs.

METHODS

A systematic literature search was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines involving articles of all languages.

INCLUSION CRITERIA

published between 1991 and 2021, spine trauma population, single country/region, and recorded time from injury to OR. The primary outcome was time from injury to OR, and the secondary outcome was LOS. Means and standard deviations were estimated in a random effects model by DerSimonian and Laird methods.

RESULTS

Of 2367 articles, 163 met the inclusion criteria for systematic review. Regarding time from injury to OR, 23 articles were eligible for meta-analysis; 16 studies were conducted in HICs and 7 in LMICs, comprising 3819 patients with TSI. A significantly shorter mean time from injury to OR was found in HICs (1.92 days, 95% confidence interval 1.44-2.41) compared with LMICs (3.27 days, 95% confidence interval 2.27-4.27) (P = 0.020). Regarding length of stay, 14 articles were eligible for meta-analysis, 10 studies were conducted in HICs and 4 in LMICs, comprising 11,003 patients. There was no difference in LOS between HICs and LMICs (25.76 days vs. 20.48 days, P = 0.140).

CONCLUSIONS

Patients with traumatic spinal injuries in HICs were more likely to undergo earlier surgery compared to patients in LMICs. No difference was found in total LOS between HICs and LMICs. While multiple factors can influence time to surgery, these findings draw attention to the global disparity in spinal trauma care.

Outcome of Cervical Spine Trauma Patients Admitted to the Intensive Care Unit at a Tertiary Government Referral Trauma Center in Nepal

STUDY DESIGN

Retrospective study.

OBJECTIVES

Cervical spinal cord injury (SCI) is a devastating event for patient and family. It has a huge impact on society because of intensive resources required to manage the patient in both acute and rehabilitation phases. With the limited resource setting in underdeveloped countries like Nepal, questions are often raised regarding whether the outcome justifies the expenses of their care. The objective was to assess the outcomes of cervical SCI patients admitted to intensive care unit (ICU).

METHODS

All cervical SCI admitted in ICU during May 2017 to August 2018 were included in this study. Demographic details, mode, morphology, and neurological level of injury, intervention performed and outcomes of ICU stay were analyzed.

RESULTS

Out of 48 patients, 36 (75%) were male and 12 female with mean age 43.9 ± 15.9 years. Fall injury was the commonest mode of injury (83.3%). Most patients presented within 1 to 3 days of injury and C5-C6 (33.3%) was the most common involved level and 75% presented with ASIA A neurology. Mechanical ventilation was required in 95.8% of the patients and 22 patients were operated upon. The average stay in ICU was 15 days and 13 patients died in the ICU.

CONCLUSIONS

Majority of cervical SCI with complete motor paraplegia required ICU care. Inspite of the intensive care, a subset of these patients succumbed to the complications of the injury. Therefore, it is essential to establish trauma ICU care with specific protocols on managing cervical spine injuries.

Spinal Cord Injury Patient's Physical and Psychological Care Needs at Home from Patients’ and Caregivers’ Perspectives: A Qualitative Study

Background: Limited studies have attempted to identify the care needs of patients with spinal cord injury (SCI) and their professional caregivers at home and after discharge from the hospital. However, little information about these needs has led to increased physical and psychological complications and thus a reduced quality of life in SCI patients. Objectives: This study aimed to explain the experiences of patients and their caregivers regarding physical and psychological care needs at home. Method: This qualitative descriptive study was conducted on 24 SCI patients and their professional caregivers using the conventional content analysis. Data were collected through unstructured and semi-structured interviews. Purposeful sampling was continued until data saturation was reached. The conventional content analysis approach proposed by Graneheim and Lundman (continuous comparison) was used to analyze the data. Results: The age range of the participants was 29 - 48 years, with an average age of 37.8 years. Seven of the participants had paraplegia, and three of them had tetraplegia. The results of data analysis led to the extraction of two main categories, including physical and psychological care needs. Conclusions: By identifying the real needs of patients after discharge from the hospital, we emphasize the need to remove barriers to home health care services and provide more financial support to meet patients' needs. Therefore, policymakers are encouraged to use the results of this study to plan at-home patient care services.

Al-Khateeb Z, Michael-Titus AT, Tremoleda JL, Hao Y. Deep learning for behaviour classification in a preclinical brain injury model

The early detection of traumatic brain injuries can directly impact the prognosis and survival of patients. Preceding attempts to automate the detection and the assessment of the severity of traumatic brain injury continue to be based on clinical diagnostic methods, with limited tools for disease outcomes in large populations. Despite advances in machine and deep learning tools, current approaches still use simple trends of statistical analysis which lack generality. The effectiveness of deep learning to extract information from large subsets of data can be further emphasised through the use of more elaborate architectures. We therefore explore the use of a multiple input, convolutional neural network and long short-term memory (LSTM) integrated architecture in the context of traumatic injury detection through predicting the presence of brain injury in a murine preclinical model dataset. We investigated the effectiveness and validity of traumatic brain injury detection in the proposed model against various other machine learning algorithms such as the support vector machine, the random forest classifier and the feedforward neural network. Our dataset was acquired using a home cage automated (HCA) system to assess the individual behaviour of mice with traumatic brain injury or non-central nervous system (non-CNS) injured controls, whilst housed in their cages. Their distance travelled, body temperature, separation from other mice and movement were recorded every 15 minutes, for 72 hours weekly, for 5 weeks following intervention. The HCA behavioural data was used to train a deep learning model, which then predicts if the animals were subjected to a brain injury or just a sham intervention without brain damage. We also explored and evaluated different ways to handle the class imbalance present in the uninjured class of our training data. We then evaluated our models with leave-one-out cross validation. Our proposed deep learning model achieved the best performance and showed promise in its capability to detect the presence of brain trauma in mice.

"God will decide her fate": the trajectories of women with traumatic spinal cord injury in India

PURPOSE

Traumatic Spinal Cord Injury (SCI) is one of the most devastating physical disabilities that unexpectedly affects physical, mental, familial, social, and economic aspects of people's lives. This article analyses the trajectories of Indian women with SCI as they attempt to access health care after the injury.

METHODS

Based on a qualitative research paradigm, this study adopts a phenomenological approach and conducts in-depth interviews with 21 Indian women with traumatic SCI.

RESULTS

(A) A lack of awareness and basic knowledge about SCI in India makes emergency response and eventual reintegration of persons with SCI in the society challenging. (B) The Indian health systems fail to meet the comprehensive health care needs of women with SCI primarily due to inadequate healthcare infrastructure and lack of empathy, accountability and knowledge about SCI among general healthcare providers. (C) The lack of patient and caregiver education results in diminished health and wellbeing of injured and their families.

CONCLUSION

The issue of SCI is not only a health issue but an issue of human rights. The persons with SCI, particularly women, must get an equitable access to health care, education, employment, transportation and other basic amenities and opportunities. Implications for rehabilitationA comprehensive response to SCI entails concerted measures such as ramping up the disability-inclusive healthcare infrastructure and enhancing the capacities of all health care providers.Besides providing rehabilitation services through the primary, secondary and tertiary levels of the health systems, India should also prioritise and offer quality community-based rehabilitation, especially in remote and rural areas.Given the unique vulnerabilities faced by women with disabilities in India, a compressive package of gender sensitive rehabilitation services needs to be integrated within the overall rehabilitation services across the country.The persons with SCI (and their families) need to be empowered through comprehensive information, counselling and skills that could help them lead independent, productive, and dignified lives.There is an urgent need to foster SCI research and make disaggregated data on SCI publicly available so that policy response to SCI is based on scientific evidence and local realities.

Ethical issues and dilemmas in spinal cord injury rehabilitation in the developing world: a mixed-method study

STUDY DESIGN

Mixed-method study (small group discussions and online literature search).

OBJECTIVES

Identify the ethical issues and dilemmas faced by rehabilitation professionals involved in the service delivery to the persons with spinal cord injury (SCI) in the low income and lower-middle-income countries (LIC/LMIC) located in Asia.

SETTING

Small group discussions in three biomedical conferences in Dhaka, Bangladesh and Kualalampur, Malaysia.

METHODS

Three small group discussions (30-45 min each) were held during three international conferences in 2019. The conferences brought together experts in the fields of neurology, rehabilitation, neurorehabilitation, and bioethics. A summary of SCI practice points and dilemmas were documented including goals of care, duties of rehabilitation professionals, health care worker-patient relationships, roles, and expectations of family members at different care settings.

RESULTS

There is a paucity of literature on this topic. The application of the principles of contemporary bioethics in the pluralistic societies of LIC/LMIC can be challenging. The ethical dilemmas faced by rehabilitation professionals working in LIC/LMIC are diverse and different from those reported from the Western and developed countries. Ethical issues and dilemmas identified were understanding patient autonomy in decision making, lack of insurance for SCI rehabilitation, financial challenges, challenges of providing emerging technology in SCI rehabilitation and SCI rehabilitation during disasters.

CONCLUSIONS

We have summarized the possible ethical issues and dilemmas which rehabilitation professionals in LIC/LMIC may encounter during delivery of SCI rehabilitation services. We hope it generates a discussion on an often-neglected aspect of SCI care in the LIC/LMIC and helps identify the complexities of ethical dilemmas unique to persons with SCI living in a developing country.

Emerging Mechanisms and Targeted Therapy of Pyroptosis in Central Nervous System Trauma

Cell death can occur in different modes, ferroptosis, pyroptosis, apoptosis, and necroptosis. Recent studies have shown that pyroptosis can be effectively regulated and that like necroptosis, pyroptosis has been regarded as a type of programmed cell death. The mechanism of its occurrence can be divided into canonical inflammasome-induced pyroptosis and noncanonical inflammasome-induced pyroptosis. In the past research, pyroptosis has been shown to be closely related to various diseases, such as tumors, neurodegenerative diseases, and central nervous system trauma, and studies have pointed out that in central nervous system trauma, pyroptosis is activated. Furthermore, these studies have shown that the inhibition of pyroptosis can play a role in protecting nerve function. In this review, we summarized the mechanisms of pyroptosis, introduce treatment strategies for targeted pyroptosis in central nervous system trauma, and proposed some issues of targeted pyroptosis in the treatment of central nervous system injury.

Evaluating a novel, low-cost technique for cervical-spine immobilization for application in resource-limited LMICs: a non-inferiority trial

STUDY DESIGN

Non-inferiority trial.

OBJECTIVE

Limited cervical spinal (c-spine) immobilization in resource-limited settings of LMICs suggests alternatives are necessary for patients with traumatic injuries. We propose a novel method of c-spine immobilization using folded towels.

SETTING

Washington University in St. Louis.

METHODS

Using non-inferiority trial design, thirty healthy patients (median age = 22) were enrolled to test the efficacy of folded towels in comparison with rigid cervical collars, foam neck braces, and no immobilization. We measured cervical range of motion (CROM) in six cardinal directions in seated and supine positions. A weighted composite score (CS) was generated to compare immobilization methods. A preserved fraction of 75% was determined for non-inferiority, corresponding to the difference between the median values for CROM between control (no immobilization) and c-collar states.

RESULTS

C-collars reduce median CROM in six cardinal directions in seated and supine positions by an average of -36.83° seated (-17.75° supine) vs. no immobilization. Folded towels and foam neck braces reduced CROM by -27° seated (-16.75° supine) and -14.25° seated (-9.5° supine), respectively. Compared to a 25% non-inferiority margin (permitting an average 9.21° of cervical movement across six cardinal directions), the CS determined folded towels are non-inferior (CS_seated = 0.89, CS_supine = 0.47). Foam neck braces are inferior (CS_seated = 2.35, CS_supine = 2.10). CS > 1 surpassed the non-inferiority margin and were deemed inferior.

CONCLUSIONS

Folded towels are a non-inferior means of immobilizing c-spine in extension and rotation, but not flexion, vs. c-collars. We propose folded towels could be trialed in combination with backboards to deliver affordable and effective prehospital TSCI management in resource-limited settings.

A Scoping Review of Registered Clinical Studies on Management of Individuals With Acute Spinal Cord Injury (2000-2020): Trends and Characteristics of the Research Initiatives

ABSTRACT

This scoping review examined the current trends and characteristics of the clinical research initiatives on the management of acute spinal cord injury. This review included all clinical studies on the acute treatment of spinal cord injury that were registered in the ClinicalTrials.gov website from February 2000 to December 2020. The search strategy combined the terms "acute spinal cord injury" and "treatment." There has been a gradual increase in the number of registered clinical studies on acute treatment of spinal cord injury over the past two decades. Of the 116 studies, there were 103 interventional studies, 12 observational studies, and 1 registry. While 115 clinical studies recruited male and female participants, most of the registered clinical studies included only adults with an upper age limit after spinal cord injury. Most of the registered clinical studies were interventional studies led by single institutions in North America (n = 70), Europe (n = 29), and Asia (n = 15). Most of the research initiatives were interventional studies on new therapies for management of individuals with spinal cord injury (n = 91). In conclusion, the results of this scoping review suggest that although there has been an increase in the amount and diversity of the research initiatives on treatment of acute spinal cord injury over the past two decades, their generalizability remains relatively limited.

Diagnosis, management and outcome of Spinal Cord Injury without Radiographic Abnormalities (SCIWORA) in adult patients with trauma: a case series

Background: Spinal cord injury without radiographic abnormality (SCIWORA) in adults causes diagnostic and prognostic dilemma as radiography and/or computed tomography does not clearly detect bone lesions during the initial assessment. Herein, we report our experience on 11 spinal cord injury cases without radiographic abnormality, regarding the clinicoradiological features, management, and outcomes.

Methods: We conducted a case series of adult patients with SCIWORA who were admitted at the level 1 trauma center at Hamad General Hospital from January 2008 to July 2018. All patients underwent initial head and spine X-ray imaging, computed tomography, magnetic resonance imaging, and 12 months of clinical follow-up.

Results: Eleven patients (mean age, 46.5 ± 14.4 years) met the criteria of SCIWORA. The neurologic status on admission and 12 months after hospital discharge were classified according to the American Spinal Injury Association (ASIA) impairment scale (AIS). On admission, 6 (54.5%) patients had ASIA grade C: 2 (18.2%) each had AIS grade D and B and 1 (9.1%) had AIS grade A. Five cases were treated conservatively with rehabilitation and physiotherapy, and five were treated surgically by anterior cervical discectomy with fusion. One patient who declined surgery was managed with a sternal occipital mandibular immobilizer brace and underwent rehabilitation.

Conclusion: SCIWORA requires higher clinical suspicion and thorough neurological and radiologic assessment to prevent secondary spinal cord injuries and complications.

Quality of Life after Surviving a Spinal Cord Injury: An Observational Study in South India

Background

Spinal cord injury (SCI) and its negative impact on the quality of life (QOL) is a significant public health concern in India. People with SCI suffer from serious health, economic, and social consequences in their lives. Often, care for SCI survivors is left to their immediate family members in India. Appropriate planning is needed for prevention, rehabilitation, health, and psychological care for SCI in the country.

Purpose

This study assessed the overall QOL of SCI survivors and their satisfaction levels with specific domains and their importance of QOL.

Materials and Methods

In this observational study, two instruments, Farrens and Power for QOL and Barthel Index for functional abilities, were administered to a convenience sample of participants drawn from Narayana Medical College, Nellore, in South India.

Results

Statistically, SCI survivors were found moderately and very satisfied with their QOL. Their perception about importance of health, functioning, social, and economic subscale also did not differ statistically.

Prehospital care for traumatic spinal cord injury by first responders in 8 sub-Saharan African countries and 6 other low- and middle-income countries: A scoping review

INTRODUCTION

Traumatic spinal cord injury (TSCI) constitutes a considerable portion of the global injury burden, disproportionately affecting low- and middle-income countries (LMICs). Prehospital care can address TSCI morbidity and mortality, but emergency medical services are lacking in LMICs. The current standard of prehospital care for TSCI in sub-Saharan Africa and other LMICs is unknown.

METHODS

This review sought to describe the state of training and resources for prehospital TSCI management in sub-Saharan Africa and other LMICs. Articles published between 1 January 1995 and 1 March 2020 were identified using PMC, MEDLINE, and Scopus databases following PRISMA-ScR guidelines. Inclusion criteria spanned first responder training programs delivering prehospital care for TSCI. Two reviewers assessed full texts meeting inclusion criteria for quality using the Newcastle-Ottawa Scale and extracted relevant characteristics to assess trends in the state of prehospital TSCI care in sub-Saharan Africa and other LMICs.

RESULTS

Of an initial 482 articles identified, 23 met inclusion criteria, of which ten were set in Africa, representing eight countries. C-spine immobilization precautions for suspected TSCI patients is the most prevalent prehospital TSCI intervention for and is in every LMIC first responder program reviewed, except one. Numerous first responder programs providing TSCI care operate without C-collar access (n = 13) and few teach full spinal immobilization (n = 5). Rapid transport is most frequently reported as the key mortality-reducing factor (n = 11). Despite more studies conducted in the Southeast Asia/Middle East (n = 13), prehospital TSCI studies in Africa are more geographically diverse, but responder courses are shorter, produce fewer professional responders, and have limited C-collar availability.

DISCUSSION

Deficits in training and resources to manage TSCI highlights the need for large prospective trials evaluating alternative C-spine immobilization methods for TCSI that are more readily available across diverse LMIC environments and the importance of understanding resource variability to sustainably improve prehospital TSCI care.

Nanoparticles in traumatic spinal cord injury: therapy and diagnosis

Nanotechnology has been previously employed for constructing drug delivery vehicles, biosensors, solar cells, lubricants and as antimicrobial agents. The advancement in synthesis procedure makes it possible to formulate nanoparticles (NPs) with precise control over physico-chemical and optical properties that are desired for specific clinical or biological applications. The surface modification technology has further added impetus to the specific applications of NPs by providing them with desirable characteristics. Hence, nanotechnology is of paramount importance in numerous biomedical and industrial applications due to their biocompatibility and stability even in harsh environments. Traumatic spinal cord injuries (TSCIs) are one of the major traumatic injuries that are commonly associated with severe consequences to the patient that may reach to the point of paralysis. Several processes occurring at a biochemical level which exacerbate the injury may be targeted using nanotechnology. This review discusses possible nanotechnology-based approaches for the diagnosis and therapy of TSCI, which have a bright future in clinical practice.

'I forget to do pressure relief': Personal factors influencing the prevention of secondary health conditions in people with spinal cord injury, South Africa

BACKGROUND

Across the lifespan, people with spinal cord injury (SCI) may experience preventable secondary health conditions (SHCs) such as pressures sores, muscle spasms and urinary tract infections (UTIs). Some factors influencing prevention of SHCs include social support, poor access to care and the prevention style of individuals. There is limited research on these factors.

OBJECTIVE

To explore personal factors influencing the prevention of SHCs in people with SCI.

METHOD

An explorative qualitative study included participants recruited in an outpatient department at a rehabilitation hospital. Semi-structured interviews were conducted with patients with SCI. Interviews were transcribed verbatim. Data analysis was conducted using content analysis.

RESULTS

Seventeen individuals with SCI were interviewed. From the interview analysis, six personal factors were identified, namely, socio-economic status; mental well-being (forgetfulness, beliefs, attitude); lack of knowledge of SHCs and prevention; lifestyle choices and practising prevention care; patient activation (self-management, problem-solving, resilience, self-awareness, help-seeking behaviour) and owning an appropriate assistive device.

CONCLUSION

Socio-economic status, mental well-being, knowledge of SHCs and prevention care, behaviour patterns, patient activation and owning an appropriate assistive device can influence prevention of SHCs. To enhance patient-oriented care, a model of care for people with SCI should consider these factors when developing prevention strategies. Future research could look into identifying environmental factors that influence the prevention of SHCs in people with SCI.

CLINICAL IMPLICATIONS

Tailored prevention strategies need to be developed, health professionals must ask patients about individual factors that may be barriers or facilitators to preventing secondary health conditions.

Regional and experiential differences in surgeon preference for the treatment of cervical facet injuries: a case study survey with the AO Spine Cervical Classification Validation Group

PURPOSE

The management of cervical facet dislocation injuries remains controversial. The main purpose of this investigation was to identify whether a surgeon's geographic location or years in practice influences their preferred management of traumatic cervical facet dislocation injuries.

METHODS

A survey was sent to 272 AO Spine members across all geographic regions and with a variety of practice experience. The survey included clinical case scenarios of cervical facet dislocation injuries and asked responders to select preferences among various diagnostic and management options.

RESULTS

A total of 189 complete responses were received. Over 50% of responding surgeons in each region elected to initiate management of cervical facet dislocation injuries with an MRI, with 6 case exceptions. Overall, there was considerable agreement between American and European responders regarding management of these injuries, with only 3 cases exhibiting a significant difference. Additionally, results also exhibited considerable management agreement between those with ≤ 10 and > 10 years of practice experience, with only 2 case exceptions noted.

CONCLUSION

More than half of responders, regardless of geographical location or practice experience, identified MRI as a screening imaging modality when managing cervical facet dislocation injuries, regardless of the status of the spinal cord and prior to any additional intervention. Additionally, a majority of surgeons would elect an anterior approach for the surgical management of these injuries. The study found overall agreement in management preferences of cervical facet dislocation injuries around the globe.

Role of pyroptosis in spinal cord injury and its therapeutic implications

BACKGROUND

Currently, spinal cord injury (SCI) is a pathological incident that triggers several neuropathological conditions, leading to the initiation of neuronal damage with several pro-inflammatory mediators' release. However, pyroptosis is recognized as a new programmed cell death mechanism regulated by the stimulation of caspase-1 and/or caspase-11/-4/-5 signaling pathways with a series of inflammatory responses.

AIM

Our current review concisely summarizes the potential role of pyroptosis-regulated programmed cell death in SCI, according to several molecular and pathophysiological mechanisms. This review also highlights the targeting of pyroptosis signaling pathways and inflammasome components and its therapeutic implications for the treatment of SCI.

KEY SCIENTIFIC CONCEPTS

Multiple pieces of evidence have illustrated that pyroptosis plays significant roles in cell swelling, plasma membrane lysis, chromatin fragmentation and intracellular pro-inflammatory factors including IL-18 and IL-1β release. In addition, pyroptosis is directly mediated by the recently discovered family of pore-forming protein known as GSDMD. Current investigations have documented that pyroptosis-regulated cell death plays a critical role in the pathogenesis of multiple neurological disorders as well as SCI. Our narrative article suggests that inhibiting the pyroptosis-regulated cell death and inflammasome components could be a promising therapeutic approach for the treatment of SCI in the near future.

Appraisal of Burden of Caregivers to Chronically Rehabilitated Patients with Spinal Cord Injuries in a Tertiary Neurological Center in Nepal

The care of a patient with a spinal cord injury is part of healthcare systems. It causes a substantial physical and emotional drain on the caretakers who often are in short supply and thus may lack adequate training, preparation, and support. Long hours of assisting a chronically handicapped patient with activities of daily living and exercises decrease the rehabilitator's quality of life and take a psychological toll that increases a risk of burnout syndrome. The present study found a significant caregiving burden among care providers of chronically dependent patients with spinal cord injuries. Additionally, financial drain escalates the issue in this rather neglected health and quality of life aspect concerning caregivers. For the situation to improve, there must be a paradigm shift in care taking toward the motivative patient's participation in the rehabilitative process. Provisions for social support and educational programs focusing on the patients and their families need to be reappraised.

Incidence of Pressure Injury in Individuals With Spinal Cord Injury: A Systematic Review and Meta-analysis

PURPOSE

The purpose of this systematic review and quantitative analysis of pooled data was to assess the global incidence of pressure injury (PI), across time frames and countries, in individuals with spinal cord injury (SCI).

DESIGN

Systematic review and meta-analysis.

SEARCH STRATEGY

PubMed, Web of Science, and EMBASE databases were systematically searched for studies published from database inception to January 2019, with only English language studies that reported the incidence of PIs in individuals with SCI were included. Study quality was assessed by a 14-item standardized checklist. We calculated the incidence of PIs as the number of new PIs in individuals with SCI and the total number of individuals with SCI during the study period. Findings are presented as incidence rate with 95% confidence intervals (CIs).

RESULTS

The search yielded 1652 studies; after studies were reviewed for inclusion criteria, 29 studies representing N = 82,722 patients were retained for data extraction. The global incidence of PIs was 0.23 (95% CI, 0.20-0.26). Data for regional distribution by country showed a pooled incidence of 0.43 (95% CI, 0.28-0.57) in individuals with SCI in South American countries, 0.36 (95% CI, 0.16-0.56) in African countries, 0.25 (95% CI, 0.14-0.37) in European countries, 0.23 (95% CI, 0.19-0.27) in North American countries, and 0.16 (95% CI, 0.06-0.25) in Asian countries. The incidence was 0.22 (95% CI, 0.19-0.26) in developing countries versus 0.27 (95% CI, 0.17-0.37) in developed countries. From 2000 to 2009, the incidence of PIs in individuals with SCI was 0.28 (95% CI, 0.09-0.47). The incidence rate of PIs before 2000 and after 2009 was 0.23. The hospital- and community-acquired PI incidence was 0.22 (95% CI, 0.19-0.26) and 0.26 (95% CI, 0.20-0.32), respectively.

CONCLUSIONS

Study findings indicate that more than 1 in 5 individuals with SCI will develop a PI. Individuals with SCI are at high risk of developing PI, especially in community settings or low- and middle-income developing countries. The findings highlight the importance of further investigation of risk factors and prevention and management strategies for PIs in individuals with SCI.

Advances in immunotherapy for the treatment of spinal cord injury

Spinal cord injury (SCI) is a leading cause of morbidity and disability in the world. Over the past few decades, the exact molecular mechanisms describing secondary, persistent injuries, as well as primary and transient injuries, have attracted massive attention to the clinicians and researchers. Recent investigations have distinctly shown the critical roles of innate and adaptive immune responses in regulating sterile neuroinflammation and functional outcomes after SCI. In past years, some promising advances in immunotherapeutic options have efficaciously been identified for the treatment of SCI. In our narrative review, we have mainly focused on the new therapeutic strategies such as the maturation and apoptosis of immune cells by several agents, mesenchymal stem cells (MSCs) as well as multi-factor combination therapy, which have recently provided novel ideas and prospects for the future treatment of SCI. This article also illustrates the latest progress in clarifying the potential roles of innate and adaptive immune responses in SCI, the progression and specification of prospective immunotherapy and outstanding issues in the area.

Recovery of motor function after traumatic spinal cord injury by using plasma-synthesized polypyrrole/iodine application in combination with a mixed rehabilitation scheme

Traumatic spinal cord injury (TSCI) can cause paralysis and permanent disability. Rehabilitation (RB) is currently the only accepted treatment, although its beneficial effect is limited. The development of biomaterials has provided therapeutic possibilities for TSCI, where our research group previously showed that the plasma-synthesized polypyrrole/iodine (PPy/I), a biopolymer with different physicochemical characteristics than those of the PPy synthesized by conventional methods, promotes recovery of motor function after TSCI. The present study evaluated if the plasma-synthesized PPy/I applied in combination with RB could increase its beneficial effects and the mechanisms involved. Adult rats with TSCI were divided into no treatment (control); biopolymer (PPy/I); mixed RB by swimming and enriched environment (SW/EE); and combined treatment (PPy/I + SW/EE) groups. Eight weeks after TSCI, the general health of the animals that received any of the treatments was better than the control animals. Functional recovery evaluated by two scales was better and was achieved in less time with the PPy/I + SW/EE combination. All treatments significantly increased βIII-tubulin (nerve plasticity) expression, but only PPy/I increased GAP-43 (nerve regeneration) and MBP (myelination) expression when were analyzed by immunohistochemistry. The expression of GFAP (glial scar) decreased in treated groups when determined by histochemistry, while morphometric analysis showed that tissue was better preserved when PPy/I and PPy/I + SW/EE were administered. The application of PPy/I + SW/EE, promotes the preservation of nervous tissue, and the expression of molecules related to plasticity as βIII-tubulin, reduces the glial scar, improves general health and allows the recovery of motor function after TSCI. The implant of the biomaterial polypyrrole/iodine (PPy/I) synthesized by plasma (an unconventional synthesis method), in combination with a mixed rehabilitation scheme with swimming and enriched environment applied after a traumatic spinal cord injury, promotes expression of GAP-43 and βIII-tubulin (molecules related to plasticity and nerve regeneration) and reduces the expression of GFAP (molecule related to the formation of the glial scar). Both effects together allow the formation of nerve fibers, the reconnection of the spinal cord in the area of injury and the recovery of lost motor function. The figure shows the colocalization (yellow) of βIII-tubilin (red) and GAP-43 (green) in fibers crossing the epicenter of the injury (arrowheads) that reconnect the rostral and caudal ends of the injured spinal cord and allowed recovery of motor function.

Pressure ulcers after traumatic spinal injury in East Africa: risk factors, illustrative case, and low-cost protocol for prevention and treatment

STUDY DESIGN

Retrospective, case-control study.

OBJECTIVES

In a traumatic spinal injury (TSI) cohort from Tanzania, we sought to: (1) describe potential risk factors for pressure ulcer development, (2) present an illustrative case, and (3) propose a low-cost outpatient protocol for prevention and treatment.

SETTING

Tertiary referral hospital.

METHODS

All patients admitted for TSI over a 33-month period were reviewed. Variables included demographics, time to hospital, injury characteristics, operative management, length of hospitalization, and mortality. Pressure ulcer development was the primary outcome. Regressions were used to report potential predictors, and international guidelines were referenced to construct a low-cost outpatient protocol.

RESULTS

Of 267 patients that met the inclusion criteria, 51 developed a pressure ulcer. Length of stay was greater for patients with pressure ulcers compared with those without (45 vs. 30 days, p < 0.001). Potential predictors for developing pressure ulcers were: increased days from injury to hospital admission (p = 0.036), American Spinal Injury Association Impairment Scale grade A upon admission (p < 0.001), and thoracic spine injury (p = 0.037). The illustrative case described a young male presenting ~2 months after complete thoracic spinal cord injury with a grade IV sacral pressure ulcer that lead to septic shock and death. Considering the dramatic consequences of pressure ulcers in lower- and middle-income countries (LMICs), we proposed a low-cost protocol for prevention and treatment targeting support surfaces, repositioning, skin care, nutrition, follow-up, and dressing.

CONCLUSIONS

Pressure ulcers after TSI in LMICs can lead to increased hospital stays and major adverse events. High-risk patients were those with delayed presentation, complete neurologic injuries, and thoracic injuries. We recommended aggressive prevention and treatment strategies suitable for resource-constrained settings.

Ormosanine improves neuronal functions in spinal cord-injured rats by blocking peroxynitrite/calpain activity

The present study was performed to evaluate the effects of ormosanine against spinal cord injury (SCI) in rats and to examine the possible molecular mechanism of action. SCI was induced using an impactor device, and rats were treated with ormosanine 10, 50 or 100 mg/kg, p.o., for 10 days after induction of SCI. The effect of ormosanine on SCI was determined by estimating neurological functions and cytokines and parameters of oxidative stress level were estimated in SCI rats. Quantitative reverse transcription polymerase chain reaction, Western blotting analysis and histopathological study were performed on spinal tissue of SCI rats. The data suggested that treatment with ormosanine reversed the alterations of neurological function in SCI rats. Moreover, the levels of cytokines, oxidative stress and reactive oxygen species production were reduced in the ormosanine treatment group compared to the SCI group. The levels of calpain and neuronal nitric oxide synthase activity were significantly reduced in the spinal tissue of the ormosanine treatment group compared to the SCI group. Moreover, ormosanine treatment reduced the percentage of viable neurons in the spinal tissue of SCI rats. In conclusion, the results of this study showed that ormosanine treatment had a protective effect against neuronal injury in spinal cord-injured rats by regulating the peroxynitrite/calpain activity.

Psychosocial challenges of social reintegration for people with spinal cord injury: a qualitative study

STUDY DESIGN

Qualitative study, using in-depth, and semi-structured interviews.

OBJECTIVE

To identify the psychosocial challenges of social reintegration for people with spinal cord injury (SCI) in Iran.

SETTING

People with SCI living in the community in Iran.

METHOD

Eleven individuals with SCI with a median time since injury of 12 years (between 9 and 20 years), two family members, and three specialists (two social workers and one physiotherapist) were selected by purposive sampling with maximum variation. In-depth and semi-structured interviews were conducted and finally the data analyzed through qualitative content methodology.

RESULTS

The psychosocial challenges were categorized into four main categories and twelve subcategories: early crises (denial and disbelief; feelings of isolation and depression; dependency crisis; and a sudden change in the normal course of life), disabling society (stigma; discrimination; employment challenges; and educational restriction), environmental barriers to access (lack of barrier-free environments and transportation challenges), and inappropriate services delivery (incomprehensive rules and lack of specialized training).

CONCLUSIONS

Providing various psychosocial services is essential for the social reintegration of people with SCI. This goal could be achieved by the provision of medical and physical rehabilitation services. The ultimate purpose of rehabilitation is to reintegrate individuals into society after injury or illness; thus, psychosocial issues must also be considered to ensure effective rehabilitation.

An Epidemiological Overview of Spinal Trauma in the Kingdom of Saudi Arabia

INTRODUCTION

The World Report on Road Traffic Injury Prevention indicates that by 2020, road traffic injuries will be a major killer, accounting for half a million deaths and 15 million disability-adjusted life years. The Kingdom of Saudi Arabia (KSA) has one of the highest rates of spinal cord injuries in the world, with 62 people injured per 1 million, and the injuries are mostly due to traffic accidents.

METHODS

All polytrauma patients associated with spinal injuries admitted to Prince Mohammed bin Abdul Aziz Hospital (PMAH), Riyadh, from January 2017 to June 2018, were included in this study. Patients with old spinal injuries, any previous spinal surgery, spine infection, or concomitant diagnosed malignancies or osteoporotic collapse with or without falls were excluded. All patients underwent whole-spine computed tomography scan and, in selective cases, magnetic resonance imaging of the spine.

RESULTS

Of the 230 patients, 90.0% were male, and 60% were in the second and third decades. Motor vehicle accidents were responsible for 83% of the cases, of which 50% of the victims were the drivers, and 80% were passengers with no seatbelt on. Nearly 50% of the spinal injuries were associated with injuries in the other body parts. Cervical spine injury accounted for 44% of the cases, followed by the lumbar spine injury. Twenty five percent of the patients presented with fixed neurologic deficit in the form of quadriplegia or paraplegia (ASIA-A). The mortality rate was 1.3%.

CONCLUSIONS

This study revealed that motor vehicle accidents are a major cause of spinal injuries in the KSA. One-fourth of the spinal Injuries are associated with complete spinal cord injuries. Therefore, in order to prevent lifelong disability in the young population, a nationwide program should be initiated to prevent road traffic accidents.

Cervical spine pathology and treatment: a global overview

Cervical spine pathology is becoming increasingly prevalent with an aging world population and is associated with significant morbidity, affecting all areas of the world. This review was undertaken to provide a global perspective on cervical spine pathology, including epidemiology, burden of disease, access to care, and plan of care in both developed and developing low- and middle-income countries (LMICs). We found that epidemiology, access to care, plan of care, and health outcomes were relatively similar between nations with similar economies. However, these aspects change dramatically when comparing developing nations to LMICs, with LMICs displaying substantial barriers to care and subsequently higher rates of morbidity and mortality. There is currently a need for large-scale, global, prospective multicenter studies that analyze not only the epidemiology and treatment of cervical spine pathology, but also consider patient outcomes.

Toward an optimization of rehabilitation services for persons with spinal cord injury in Mongolia: the perspective of medical doctors

PURPOSE

To explore medical doctors' views on what are barriers in providing rehabilitation services for persons with SCI in Mongolia.

METHODS

A qualitative study with semi-structured interviews was conducted with 12 medical doctors. Participants were purposely sampled. The World Health Organization (WHO)'s report International Perspectives on Spinal Cord Injury was chosen as a guide to structure the interviews. The study used inductive thematic analysis.

RESULTS

Five barriers in the provision of rehabilitation services were identified: low awareness and limited knowledge regarding SCI and rehabilitation issues, inadequate rehabilitation policies, deficiencies in infrastructure, deficiencies in equipment and medication, and a shortage of well-prepared rehabilitation workforce.

CONCLUSIONS

Based on WHO recommendations "Rehabilitation in health systems", this study provides suggestions on how to strengthen rehabilitation services in Mongolia to better respond to the needs of the SCI population. Our findings highlight that a core issue is the lack of awareness among policymakers regarding rehabilitation and its benefits at the micro, meso and macro levels of the health system. Actions are needed at the level of health policies to ensure, for instance, adequate financing and access to the services. Also, synergies between the Ministries of Education and Health can improve the training of the workforce.Implications for rehabilitationEvidence that rehabilitation services contribute to improving health outcomes and cost-effectiveness could raise awareness among Mongolian policymakers and inform their decisions on funding schemes.Health policies in Mongolia should be reformed to remove barriers in the provision of rehabilitation services for persons with complex and chronic health conditions.Rehabilitation services need to be included into the Mongolian health insurance scheme in order to improve the quality and accessibility of rehabilitation services.Synergies between the Ministry of Education and the Ministry of Health in Mongolia are needed to develop training standards for rehabilitation professionals.

Treatment of patients with cervical and upper thoracic incomplete spinal cord injury using repetitive transcranial magnetic stimulation

PURPOSE

To evaluate the short- and long-term effectiveness of repetitive transcranial magnetic stimulation with parameters based on results of comparative neurophysiological studies in patients with incomplete spinal cord injury. Results may help to understand mechanisms responsible for regeneration of the incomplete spinal cord after injury.

METHODS

Repetitive transcranial magnetic stimulation sessions (three to five sessions per month for not less than 5 months) to 15 patients with C4-Th2 incomplete spinal cord injury were applied with individually designed parameters. One session consisted of bilateral stimulation of the primary motor cortex (for 10 min each with 800 stimuli in 2-s lasting trains and the inter-train intervals of 28 s) with frequency at 20-22 Hz and stimulus strength that was 70%-80% of the resting motor threshold (0.84-0.96 T). Recordings of surface electromyography at rest and during the attempt of maximal muscle contractions and motor evoked potentials were performed from abductor pollicis brevis and tibialis anterior muscles bilaterally. Amplitude parameters of surface electromyography and motor evoked potentials were used as outcomes. All neurophysiological tests were comparatively applied before and after treatment.

RESULTS

Decrease in surface electromyography amplitudes recorded at rest from abductor pollicis brevis (p = 0.009), increase in surface electromyography amplitudes during maximal contraction of abductor pollicis brevis (p = 0.03) and increase in motor evoked potential parameters recorded from abductor pollicis brevis (p = 0.04) were found.

CONCLUSION

Proposed repetitive transcranial magnetic stimulation algorithm reduced the increased muscle tension in upper extremity muscles, improved the function of upper extremity muscle motor units and slightly improved the transmission of efferent neural impulses within spinal pathways. Besides functional recovery in descending spinal pathways, repetitive transcranial magnetic stimulation may also inhibit inevitable pathological changes in nerves.

Path to Prevention of Spinal Trauma in a Low- to Middle-income Country: A Single-center Study in Phnom Penh, Cambodia

This study sought to characterize the epidemiology and outcomes of spinal trauma, with or without a neurologic deficit, at a major government hospital in Phnom Penh, Cambodia. Patient demographics, American Spinal Injury Association (ASIA) score on presentation, location of injury, and cause of injury from 316 patients from September 2013 through December 2016 were compiled. Outcome measures included length of hospitalization and surgical intervention. Falls were the leading cause of spinal injury (50.6%), followed by motor vehicle accidents (29.3%) and other accidents (20.1%). Patients who fell from height had higher surgery rates (P = 0.014), and men had worse ASIA scores (P = 0.0013). Patients with ASIA A-C had a mean age of 38.17 years, whereas the D-E group was on average 42.88 years. Motor vehicle accidents caused the most cervical spine injuries, whereas falls caused more thoracic and lumbar trauma (P = 0.0005). Younger, working men are experiencing more severe spinal injuries, undergoing more surgery, and staying hospitalized longer than other demographics in Phnom Penh. This study characterizes spinal trauma from falls as a public health issue in Cambodia, highlighting the importance of fall injury prevention. Protecting this cohort is an important investment for Cambodia and necessitates workplace reform and safety standard implementation.

Clinical Characteristics and Challenges of Management of Traumatic Spinal Cord Injury in a Trauma Center of a Developing Country

Background  Traumatic spinal cord injury (TSCI) is a major burden in trauma care worldwide. Most victims are young, and the injury results in economic loss and psychological and social burden on the individual and the society. The outcome depends on the severity of primary spinal cord injury, interventions to prevent secondary insults to the damaged cord, and access to a specialized care. The lack of standard prehospital care and dedicated facilities for spine care coupled with challenges of inadequate health insurance coverage impact negatively on the outcome of care in patients with spinal cord injury in our practice. Objectives  This study was performed to determine the clinical profile of patients with TSCI and to highlight the factors that determine the early outcome in a resource-constrained trauma center. Materials and Methods   This study was a retrospective review of trauma registry and medical records of all the patients with acute TSCI at the National Trauma Center Abuja from September 2014 to December 2016. Results  A total of 133 patients with TSCI were studied. Most of these patients were young men with a mean age of 36 years. Most injury (72.2%) occurred following motor vehicular crash affecting mainly the cervical spinal cord (62.0%). None of the patients received standard prehospital care. Only 41.4% of the patients were transported to the hospital in an ambulance. About half (52.6%) of the patients suffered complete spinal cord injury (the American Spinal Injury Association [ASIA] A), and pressure ulcer was the most common complication (23.3%). Only 42% of the patients that needed surgical intervention were operated, mainly due to the inability to pay for the service. The ASIA grade on admission was the most significant determinant factor of morbidity and mortality. Conclusion  Optimal care of patients with TSCI was hindered by inadequate facilities and economic constraints.

Heterogeneity and Its Impact on Rehabilitation Outcomes and Interventions for Community Reintegration in People With Spinal Cord Injuries: An Integrative Review

Background: Various injury characteristics such as cause, level, severity, and time since injury divide individuals with spinal cord injury (SCI) into many subgroups. The heterogeneity among individuals' injuries and personal characteristics has significant implications for SCI rehabilitation practice, specifically directed toward community reintegration, which is a key goal of rehabilitation interventions for people with disabilities. Purpose: This study aims to summarize the evidence on attributes that make the SCI population heterogeneous, the impact of these attributes on community reintegration, and the implications of heterogeneity for rehabilitation interventions directed toward optimizing community reintegration. Methods: We used an integrative review approach to conduct this study. MEDLINE, PubMed, CINAHL, EMBASE, Google Scholar, and PsycINFO were searched from inception until May 2017. Out of 670 articles retrieved, 49 provided evidence on the impact of various attributes that make SCI heterogeneous on rehabilitation outcomes related to community reintegration. Results: An array of injury-related, personal, social, and environmental factors are associated with various rehabilitation outcomes that affect community reintegration of people with SCI. There is level 1 evidence that social support, self-efficacy, and self-esteem facilitate community reintegration among people with SCI while there is level 5 evidence that presence of psychological or medical complications decreases it. There is lack of clarity on the impact of injury-related factors on community reintegration. Conclusion: This integrative review found that social support and individuals' self-efficacy can improve community reintegration of people with SCI. However, evidence regarding the impact of injury characteristics on community reintegration is still underdeveloped. Approaches directed at community reintegration should involve components of psychosocial, physical, and vocational rehabilitation while considering personal and societal aspects of an individual's life.
