Abstract
BACKGROUND Zebrafish are vertebrates with a high potential of regeneration after injury in the central nervous system. Therefore, they have emerged as a useful model system for studying traumatic spinal cord injuries. NEW METHOD Using larval zebrafish, we have developed a robust paradigm to model the effects of anterior spinal cord injury, which correspond to the debilitating injuries of the cervical and thoracic regions in humans. Our new paradigm consists of a more anterior injury location compared to previous studies, a modified behavioral assessment using the visual motor response, and a new data analysis code. RESULTS Our approach enables a spinal cord injury closer to the hindbrain with more functional impact compared to previous studies using a more posterior injury location. Results reported in this work reveal recovery over seven days following spinal cord injury. COMPARING WITH EXISTING METHODS The present work describes a modified paradigm for the in vivo study of spinal cord regeneration after injury using larval zebrafish, including an anterior injury location, a robust behavioral assessment, and a new data analysis software. CONCLUSIONS Our findings lay the foundation for applying this paradigm to study the effects of drugs, nutrition, and other treatments to improve the regeneration process.

Abstract
Background The inclusion of people living with spinal cord injury (SCI) in research has allowed for an informed understanding of priorities of recovery of which bowel dysfunction and bladder dysfunction have been continuously identified. Research has also demonstrated the global disparities in SCI outcomes particularly when comparing high- and low-income countries. Currently, there is a lack of direct comparison between countries when assessing SCI outcomes. Objectives This is an exploratory study to better understand bowel and bladder dysfunction amongst individuals with SCI in India and Canada. Methods Data from 33 participants were analyzed. Participants completed an online questionnaire assessing demographic information and the Neurogenic Bowel Dysfunction (NBD) score, Wexner score, Neurogenic Bladder Symptom Score (NBSS), and the Incontinence Quality of Life Instrument (I-QOL). Continuous data were compared using t tests. For not normally distributed data, the independent Mann-Whitney U test was used. Categorical variables were evaluated for association using Fisher's exact or chi-square test, depending on the sample size. Results Independent Mann-Whitney U test demonstrated that the Canadian participants had poorer bowel function with higher total NBD scores (p = .007) and less frequent bowel movements (p = .036), and they were more likely to experience uneasiness, headaches, and perspiration during bowel movements (p < .001). NBSS results indicated a small but significantly higher proportion of the Indian participants were unsatisfied or unhappy with their bladder function (p = .049). The distribution of Wexner and I-QOL scores were the same across countries. Conclusion Potential explanations for differences include lifestyle, management, financial resources, patient and caregiver education, and societal pressures, which are all heavily influenced by cultural, geographical, and economic circumstances.

Abstract
This study investigated Cerium oxide nanoparticles (CeONPs) effect on central neuropathic pain (CNP). The compressive method of spinal cord injury (SCI) model was used for pain induction. Three groups were formed by a random allocation of 24 rats. In the treatment group, CeONPs were injected above and below the lesion site immediately after inducing SCI. pain symptoms were evaluated using acetone, Radian Heat, and Von Frey tests weekly for six weeks. Finally, we counted fibroblasts using H&E staining. We evaluated the expression of Cx43, GAD65 and HDAC2 proteins using the western blot method. The analysis of results was done by PRISM software. At the end of the study, we found that CeONPs reduced pain symptoms to levels similar to those observed in normal animals. CeONPs also increased the expression of GAD65 and Cx43 proteins but did not affect HDAC2 inhibition. CeONPs probably have a pain-relieving effect on chronic pain by potentially preserving GAD65 and Cx43 protein expression and hindering fibroblast infiltration.

Abstract
PURPOSE Standard manual wheelchairs (MWCs) are inefficient and pushrim propulsion may cause progressive damage and pain to the user's arms. We describe a wheel for a MWC with a novel propulsion mechanism. METHODS The wheel has two modes of operation called "Standard" mode and "Run" mode. In Run mode, the wheelchair is propelled forward by pushing a compliant handle forward and then pulling it back, both strokes contributing to forward propulsion. We report the propulsive force and preliminary testing on a rough outdoor circuit by three able-bodied participants. RESULTS In Run mode, the peak applied force is reduced to 30% and the maximum force gradient is reduced to 10% of that for standard pushrim propulsion, for the same work output. The travel time for the 1.06 km outdoor circuit is about 60% of that for a brisk walk and about 40% of that for pushrim propulsion. At a propulsion speed of 1 m/s, the cardiovascular effort in Run mode is 56% of that for pushrim propulsion. Automatic hill-hold in Run mode improves safety when ascending slopes. The mechanism has three gears so that it can be used by people with widely varying strength and fitness. Folding the handle away converts the operation to Standard mode with the conventional pushrim propulsion, supplemented by three gears. CONCLUSIONS Despite the increased weight, width and friction, the bimodal geared wheels facilitate wheelchair travel on challenging paths. This may bring significant improvement to the quality of life of MWC users.

Abstract
Spinal cord injury (SCI) is a neurodegenerative disorder that has critical impact on patient's life expectance and life span, and this disorder also leads to negative socioeconomic features. SCI is defined as a firm collision to the spinal cord which leads to the fracture and the dislocation of vertebrae. The current available treatment is surgery. However, it cannot fully treat SCI, and many consequences remain after the surgery. Accordingly, finding new therapeutics is critical. BDNF-TrkB signaling is a vital signaling in neuronal differentiation, survival, overgrowth, synaptic plasticity, etc. Hence, many studies evaluate its impact on various neurodegenerative disorders. There are several studies evaluating this signaling in SCI, and they show promising outcomes. It was shown that various exercises, chemical interventions, etc. had significant positive impact on SCI by affecting BDNF-TrkB signaling pathway. This study aims to accumulate and evaluate these data and inspect whether this signaling is effective or not.

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.

Abstract
Background/Objectives: Spinal cord injuries are debilitating conditions with significant impacts on physical function and patient quality of life. The high incidence of urinary tract infections in these patients can be attributed to neurogenic bladder-a major complication of spinal cord injuries. The aim of this study is to investigate the incidence of urinary tract infections in patients with spinal cord injuries and their relation to the method of bladder emptying. Methods: A retrospective analysis on 560 patients admitted for rehabilitation at the Clinic for Rehabilitation "Dr Miroslav Zotovic" from December 2009 to January 2023 was conducted. Patients over 18 years old who were inpatients for longer than 30 days without any symptoms of urinary tract infection on admission were included. Patient demographics, injury details, and bladder emptying methods were recorded. Results: In our study, 402 (71.8%) participants developed a urinary tract infection during their rehabilitation. Urinary tract infections were significantly more common in patients with traumatic spinal cord injuries, lower ASIA scores, and thoracic-level injuries. The highest incidence of urinary tract infections was observed in intermittent self-catheterization patients (62.7%), with Escherichia coli and Proteus mirabilis being the most frequently isolated pathogens. Conclusions: The method of bladder emptying significantly impacted the incidence of urinary tract infection in patients with spinal cord injuries. Despite guidelines favoring intermittent catheterization, this study found it to be associated with the highest infection rates. These findings suggest a need for personalized bladder management strategies to reduce the risk of urinary tract infections and improve outcomes for spinal cord injury patients.

Abstract
BACKGROUND Spinal cord injury (SCI) is a consequence of significant disability and health issues globally, and long COVID represents the symptoms of neuro-musculoskeletal, cardiovascular and respiratory complications. PURPOSE This study aimed to identify the symptom responses and disease burden of long COVID in individuals with spinal cord injury. METHODS This case-control study was conducted on patients with SCI residing at a specialised rehabilitation centre in Bangladesh. Forty patients with SCI with and without long COVID symptoms (LCS) were enrolled in this study at a 1:1 ratio according to WHO criteria. RESULT Twelve LCS were observed in patients with SCI, including fatigue, musculoskeletal pain, memory loss, headache, respiratory problems, anxiety, depression, insomnia, problem in ADL problem in work, palpitation, and weakness. The predictors of developing long COVID include increasing age (p<0.002), increasing BMI (p<0.03), and longer duration of spinal cord injury (p<0.004). A significant difference (p<0.01) in overall years of healthy life lost due to disability (YLD) for non-long COVID cases was 2.04±0.596 compared to long COVID (LC) cases 1.22±2.09 was observed. CONCLUSION Bangladeshi patients of SCI presented 12 long COVID symptoms and have a significant disease burden compared to non long COVID cases.

Abstract
Disorders related to gut health are a significant cause of morbidity among athletes in wheelchair. This pilot feasibility trial aims to investigate whether probiotics compared to prebiotics can improve inflammatory status and gut microbiome composition in elite athletes in wheelchair. We conducted a 12-week, randomized, cross-over controlled trial involving 14 elite Swiss athletes in wheelchair. Participants were given a multispecies-multistrain probiotic or prebiotic (oat bran) daily for 4 weeks (Clinical trials.gov NCT04659408 09/12/2020). This was followed by a 4-week washout and then crossed over. Thirty inflammatory markers were assessed using bead-based multiplex immunoassays (LegendPlex) from serum samples. The gut microbiome was characterized via 16S rRNA sequencing of stool DNA samples. Statistical analyses were conducted using linear mixed-effect models (LMM). At baseline, most athletes (10/14) exhibited low levels of inflammation which associated with higher gut microbiome alpha diversity indices compared to those with high inflammation levels. The use of probiotic had higher decrease in 25 (83%) inflammatory markers measured compared to prebiotic use. Probiotic has the potential in lowering inflammation status and improving the gut microbiome diversity. The future trial should focus on having sufficient sample sizes, population with higher inflammation status, longer intervention exposure and use of differential abundance analysis.

All acute care hospitalizations for SCI of adults ages 18 to 64 years were included. A comparison group was constructed by sampling from individuals in the injured cohort. Fiscal information from their preinjury years was used for comparison. The injured cohort was matched with the comparison group based on age, sex, marital status, province of residence, self-employment status, earnings, and employment status in the year prior to injury. Data were analyzed from August 2022 to January 2023. Main outcomes and Measures The first outcome was the change in individual annual earnings up to 5 years after injury. The change in mean yearly earnings was assessed using a linear mixed-effects differences-in-differences regression. Income values are reported in 2022 Canadian dollars (CAD $1.00 = US $0.73). The second outcome was the change in employment status up to 5 years after injury. A multivariable probit regression model was used to compare proportions of individuals employed among those who had experienced SCI and the paired comparison group of participants. Results A total of 1630 patients with SCI (mean [SD] age, 47 [13] years; 1304 male [80.0%]) were matched to patients in a preinjury comparison group (resampled from the same 1630 patients in the SCI group). The mean (SD) of preinjury wage earnings was CAD $46 000 ($48 252). The annual decline in individual earnings was CAD $20 275 (95% CI, -$24 455 to -$16 095) in the first year after injury and CAD $20 348 (95% CI, -$24 710 to -$15 985) in the fifth year after injury. At 5 years after injury, 52% of individuals who had an injury were working compared with 79% individuals in the preinjury comparison group. SCI survivors had a decrease in employment of 17.1 percentage points (95% CI, 14.5 to 19.7 percentage points) in the first year after injury and 17.8 percentage points (14.5 to 21.1 percentage points) in the fifth year after injury. Conclusions and Relevance In this study, SCI was associated with a decline in earnings and employment up to 5 years after injury for adults aged 18 to 64 years in Canada.

Enhancing regenerative potential: A comprehensive review of stem cell transplantation for sports-related neuronal injuries, with a focus on spinal cord injuries and peripheral nervous system damage. Tissue Cell 2024; 88:102429. [PMID: 38833939 DOI: 10.1016/j.tice.2024.102429] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 05/28/2024] [Accepted: 05/30/2024] [Indexed: 06/06/2024]
Abstract
Neuronal injuries, as one of the consequences of sports-related incidents, exert a profound influence on the athletes' future, potentially leading to complete immobility and impeding their athletic pursuits. In cases of severe damage inflicted upon the spinal cord (SC) and peripheral nervous systems (PNS), the regenerative process is notably compromised, rendering it essentially inefficient. Among the pivotal therapeutic approaches for the enhancement and prevention of secondary SC injuries (SCI), stem cell transplantation (SCT) stands out prominently. Stem cells, whether directly involved in replacement and reconstruction or indirectly through modification and secretion of crucial bioenvironmental factors, engage in the intricate process of tissue regeneration. Stem cells, through the secretion of neurotrophic factors (NTFs) (aiming to modulate the immune system), reduction of inflammation, axonal growth stimulation, and myelin formation, endeavor to facilitate the regeneration of damaged SC tissue. The fundamental challenges of this approach encompass the proper selection of suitable stem cell candidates for transplantation and the establishment of an appropriate microenvironment conducive to SC repair. In this article, an attempt has been made to explore sports-related injuries, particularly SCI, to comprehensively review innovative methods for treating SCI, and to address the existing challenges. Additionally, some of the stem cells used in neural injuries and the process of their utilization have been discussed.

Abstract
This study aims to elucidate the key regulatory molecules, specifically messenger RNAs (mRNAs), long noncoding RNAs (lncRNAs), and microRNAs (miRNAs) and their roles in the development and progression of spinal cord injury (SCI). Expression profiles (GSE45006, GSE19890, and GSE125630) for SCI were sourced from the Gene Expression Omnibus (GEO) database. By comparing rats with SCI at various time points against those without SCI, we identified differentially expressed mRNAs (DEmRNAs), lncRNAs (DElncRNAs), and miRNAs (DEmiRNAs). The GSE45006 dataset facilitated the production of DEmRNAs, which were then clustered using Mfuzz. Subsequently, we constructed a protein-protein interaction (PPI) network and anticipated interaction pairs between miRNA-mRNA and lncRNA-mRNA. These pairs were instrumental in forming a regulatory network involving lncRNA-miRNA-mRNA interactions. Additionally, we conducted functional enrichment studies on the DEmRNAs within these gene networks. A total of 2313 DEmRNAs were identified using the GSE45006 dataset, alongside 111 DEmiRNAs from GSE19890. From GSE125630, we extracted 154 DElncRNAs and 2322 DEmRNAs. Our analysis revealed 294 up-regulated DEmRNAs, grouped into the up-cluster, and 407 down-regulated DEmRNAs, forming the down-cluster. Key hub genes in the PPI network, such as Rhof, Vav1, Lyz2, Rab3a, Lyn, Cyfip1, Gns, and Nckap1l, were identified. Additionally, the study successfully constructed a competing endogenous RNA (ceRNA) network, revealing 55 unique lncRNA-miRNA-mRNA link pairs. Our research established a ceRNA network associated with SCI, identifying several critical lncRNA-miRNA-mRNA connection pairs integral to the disease's onset and progression. Notably, significant associations, including the AABR07041411.1-miR-125a-5p-Slc4a7 and the Smg1-rno-miR-331-3p-Tlr4 pairs, were observed to exert a significant influence within this biological context.

Abstract
PURPOSE To gain knowledge of the experiences and perceptions of using fitness apps by full-time wheelchair users with spinal cord injury (SCI) and to explore experiences and perceptions of using these apps in relation to barriers to and facilitators of physical activity (PA). MATERIALS AND METHODS A qualitative design was employed. Semi-structured interviews were conducted with ten manual wheelchair users with SCI. Data were analysed using reflexive thematic analysis. RESULTS Four themes were developed: 1) App functionality and experience, 2) Enhancing motivation, 3) Precursors to engagement and 4) Knowledge gaps. Experience and perception were strongly influenced by app design, particularly the presence or absence of features tailored for wheelchair users. Many apps incorporated the use wearable or mountable sensors. Fitness apps were perceived to increase motivation, although, this had its limitations. Conversely, apps were reported to have limited influence on commonly reported barriers to PA. Furthermore, the data highlighted gaps in knowledge which created barriers to effective app use. CONCLUSIONS Fitness apps were perceived to increase motivation to engage in PA in manual wheelchair users with SCI. However, more needs to be done to further develop app features for wheelchair users with SCI and to address remaining barriers to engagement.

Abstract
Spinal cord injury (SCI) represents a severe trauma to the nervous system, leading to significant neurological damage, chronic inflammation, and persistent neuropathic pain. Current treatments, including pharmacotherapy, immobilization, physical therapy, and surgical interventions, often fall short in fully addressing the underlying pathophysiology and resultant disabilities. Emerging research in the field of regenerative medicine has introduced innovative approaches such as autologous orthobiologic therapies, with bone marrow aspirate (BMA) being particularly notable for its regenerative and anti-inflammatory properties. This review focuses on the potential of BMA to modulate inflammatory pathways, enhance tissue regeneration, and restore neurological function disrupted by SCI. We hypothesize that BMA's bioactive components may stimulate reparative processes at the cellular level, particularly when applied at strategic sites like the sacral hiatus to influence lumbar centers and higher neurological structures. By exploring the mechanisms through which BMA influences spinal repair, this review aims to establish a foundation for its application in clinical settings, potentially offering a transformative approach to SCI management that extends beyond symptomatic relief to promoting functional recovery.

Abstract
Abstract Epidural spinal cord stimulation (eSCS) of the lower thoracic spinal cord has been shown to partially restore volitional movement in patients with complete chronic spinal cord injury (cSCI). Combining eSCS with intensive locomotor training improves motor function, including standing and stepping, but many patients with cSCI suffer from long-standing muscle atrophy and loss of bone mineral density, which may prohibit safe implementation. Safe, accessible, and effective avenues for pairing neuromodulation with activity-based therapy remain unexplored. Cycling is one such option that can be utilized as an eSCS therapy given its low-risk and low-weight-bearing requirement. We investigated the feasibility and kinematics of motor-assisted and passive cycle-based therapy for cSCI patients with epidural spinal cord stimulation. Seven participants who underwent spinal cord stimulation surgery in the Epidural Stimulation After Neurologic Damage (E-STAND) trial (NCT03026816) participated in a cycling task using the motor assist MOTOmed Muvi 300. A factorial design was used such that participants were asked to cycle with and without conscious effort with and without stimulation. We used mixed effects models assessing maximum power output and time pedaling unassisted to evaluate the interaction between stimulation and conscious effort. Cycling was well-tolerated and we observed no adverse events, including in participants up to 17 years post-initial injury and up to 58 years old. All participants were found to be able to pedal without motor assist, which primarily occurred when stimulation and effort were applied together (p = 0.001). Additionally, the combination of stimulation and intention was significantly associated with higher maximum power production (p < 0.0001) and distance pedaled (p = 0.0001). No association was found between volitional movement and participant factors: age, time since injury, and spinal cord atrophy. With stimulation and conscious effort, all participants were able to achieve active cycling without motor assistance. Thus, our stationary cycling factorial study design demonstrated volitional movement restoration with eSCS in a diverse study population of cSCI participants. Further, motor-assist cycling was well-tolerated without any adverse events. Cycling has the potential to be a safe research assessment and physical therapy modality for cSCI patients utilizing eSCS who have a high risk of injury with weight bearing exercise. The cycling modality in this study was demonstrated to be a straightforward assessment of motor function and safe for all participants regardless of age or time since initial injury.

Abstract
Spinal cord injury (SCI) research and policy decisions are rarely made in partnership with people with SCI, making them less relevant, applicable, and used by those whom the decisions are intended to support. Across disciplines, consensus methods have been promoted as a viable solution for supporting shared research and policy-based decision-making. In this paper, we describe a partnered approach between academic researchers and the Ontario SCI Alliance, a non-profit, SCI community mobilization network to co-develop and co-disseminate a community-based consensus exercise. The community-based consensus exercise included two modified Delphi surveys and one in-person retreat. The partnership's goal with this exercise was to facilitate shared decision-making for the development of their upcoming strategic plan. We then interviewed partners and participants from the Delphi and in-person retreat to discuss successes, challenges, and lessons learned from the exercise. Survey 1 was disseminated to over 2,500 members of the Ontario SCI community and received 374 responses (276 coming from people with SCI). Survey 2 had 118 responses, with 87 coming from people with SCI. The retreat had 73 attendees, including people with SCI, family/friends of people with SCI, clinicians, researchers, and SCI community and research organization staff/volunteers. The retreat included a presentation of the survey results, a clinician/researcher panel, and externally-facilitated working groups. All survey responses and retreat materials were synthesized. Using the synthesized feedback, the Ontario SCI Alliance was able to implement several changes for the Ontario SCI community, including higher-quality primary care experiences (reduced wait times, more accessible examining rooms), the development of a wound care strategy with the Ontario government, and an advocacy campaign for public coverage for catheters and urinary care supplies. From the five interviews conducted, five themes were co-constructed regarding the successes, challenges, and lessons learned from the exercise: (1) Inclusion, Diversity, Equity, and Accessibility; (2) Partnership; (3) Design Considerations; (4) Transparency and Clarity in Communication; and (5) Sustainability. Findings from this community case study demonstrate the feasibility of conducting a community-level consensus exercise among an equity-deserving group while providing detailed guidance for how to ensure future research and policy-based decision-making is shared across diverse knowledge users.

Epidural Spinal Cord Stimulation for Spinal Cord Injury in Humans: A Systematic Review. J Clin Med 2024; 13:1090. [PMID: 38398403 PMCID: PMC10889415 DOI: 10.3390/jcm13041090] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Revised: 02/09/2024] [Accepted: 02/12/2024] [Indexed: 02/25/2024] Open
Abstract
(1) Background: Spinal cord injury (SCI) represents a major health challenge, often leading to significant and permanent sensorimotor and autonomic dysfunctions. This study reviews the evolving role of epidural spinal cord stimulation (eSCS) in treating chronic SCI, focusing on its efficacy and safety. The objective was to analyze how eSCS contributes to the recovery of neurological functions in SCI patients. (2) Methods: We utilized the PRISMA guidelines and performed a comprehensive search across MEDLINE/PubMed, Embase, Web of Science, and IEEE Xplore databases up until September 2023. We identified studies relevant to eSCS in SCI and extracted assessments of locomotor, cardiovascular, pulmonary, and genitourinary functions. (3) Results: A total of 64 studies encompassing 306 patients were identified. Studies investigated various stimulation devices, parameters, and rehabilitation methods. Results indicated significant improvements in motor function: 44% of patients achieved assisted or independent stepping or standing; 87% showed enhanced muscle activity; 65% experienced faster walking speeds; and 80% improved in overground walking. Additionally, eSCS led to better autonomic function, evidenced by improvements in bladder and sexual functions, airway pressures, and bowel movements. Notable adverse effects included device migration, infections, and post-implant autonomic dysreflexia, although these were infrequent. (4) Conclusion: Epidural spinal cord stimulation is emerging as an effective and generally safe treatment for chronic SCI, particularly when combined with intensive physical rehabilitation. Future research on standardized stimulation parameters and well-defined therapy regimens will optimize benefits for specific patient populations.

Abstract
INTRODUCTION AND OBJECTIVE Individuals with spinal cord injury (SCI) commonly experience secondary complications though it is not known how they prioritize these different health domains. Using the Neurogenic Bladder Research Group (NBRG) SCI registry, our objective was to identify the top health concerns of individuals with SCI and identify factors that may be associated with these choices with particular focus on urologic issues that participants face. METHODS Participants in the NBRG registry were asked: "What are the top 3 problems that affect you on a daily basis?" Urinary symptoms and QoL were assessed with the Neurogenic Bladder Symptom Score (NBSS). Multivariate regression was used to identify factors related to selecting a top ranked health issue. RESULTS Among our 1461 participants, 882 (60.4%) were men and the median age was 45.1 years (IQR 25.3-64.9). Bladder management was the most commonly top ranked primary issue (39%) followed by pain (16.4%) and bowel management (11.6%). Factors associated with ranking bladder management as the primary concern included years since injury (OR 1.01 [1.00-1.02], p = 0.042), higher (worse) total NBSS (OR 1.05 [1.03-1.06], p < 0.001), and higher (worse) NBSS QoL (OR 1.25 [1.12-1.41], p < 0.001). Reporting chronic pain on a daily basis was associated with ranking pain as the primary health concern (OR 41.7 [15.7-170], p < 0.001). CONCLUSIONS In this cohort, bladder management was ranked as the top health issue and increasing time from injury was associated with increased concern over bladder management. More bladder symptoms were also associated with ranking bladder management as a primary concern while bladder management method and urinary tract infections rate were not.

Abstract
PURPOSE Activity-based locomotor training improves intrinsic trunk control in children with spinal cord injury (SCI). To reinforce these improvements, there is a need to develop community integration activities to allow a patient to apply the retrained nervous system at home. One activity that has been explored is rocking in a rocking chair. This paper describes the design, fabrication, and evaluation of a rocking chair for children with SCI. MATERIALS AND METHODS The Quality Function Deployment (QFD) design process was used. Fundamental needs and features for the rocking chair were defined in a focus group with experienced therapists, and needs were then rated for importance. A House of Quality (HOQ) matrix was developed to correlate needs with design features, and a prototype design was generated. Virtual motion studies and finite element analysis (FEA) were utilized to assess the design. The chair was fabricated and physical testing was performed, including tipping and static and dynamic load assessments. RESULTS AND CONCLUSIONS The needs identified through the QFD process were categorized into (1) safety, (2) therapeutic, (3) practical and aesthetic, and (4) data to track chair use. Features selected to meet these needs include safety stops, padding, straps, a stable base, armrests, adjustable footrest, and sensors to capture rocking data. FEA showed a factor of safety (FOS) > 5. Physical testing confirmed physical integrity, load-bearing capacity, and stability of the prototype glider rocking chair. The prototype provides a safe tool for further investigation of rocking for promotion of trunk muscle activation in children with SCI.

Abstract
Spinal cord injury (SCI) is a devastating event that significantly changes daily function and quality of life and is linked to bowel and bladder dysfunction and frequent antibiotic treatment. We aimed to study the composition of the gut microbiome in individuals with SCI during the initial sub-acute rehabilitation process and during the chronic phase of the injury. This study included 100 fecal samples from 63 participants (Median age 40 years, 94% males): 13 cases with SCI in the sub-acute phase with 50 longitudinal samples, 18 cases with chronic SCI, and 32 age and gender-matched controls. We show, using complementary methods, that the time from the injury was a dominant factor linked with gut microbiome composition. Surprisingly, we demonstrated a lack of gut microbial recovery during rehabilitation during the sub-acute phase, with further deviation from the non-SCI control group in the chronic ambulatory SCI group. To generalize the results, we were able to show significant similarity of the signal when comparing to a previous cohort with SCI, to subjects from the American Gut Project who reported low physical activity, and to subjects from another population-based cohort who reported less normal stool consistency. Restoration of the microbiome composition may be another desirable measure for SCI recovery in the future, but further research is needed to test whether such restoration is associated with improved neurological outcomes and quality of life.

Abstract
Background Transcutaneous Spinal Stimulation (TSS) has been shown to promote activation of the lower limb and trunk muscles and is being actively explored for improving the motor outcomes of people with neurological conditions. However, individual responses to TSS vary, and often the muscle responses are insufficient to produce enough force for self-supported standing. Functional electrical stimulation (FES) can activate individual muscles and assist in closing this functional gap, but it introduces questions regarding timing between modalities. Methods To assess the effects of TSS and FES on force generation, ten neurologically intact participants underwent (1) TSS only, (2) FES only, and (3) TSS + FES. TSS was delivered using four electrodes placed at T10-T11 through the L1-L2 intervertebral spaces simultaneously, while FES was delivered to the skin over the right knee extensors and plantarflexors. For all conditions, TSS and FES were delivered using three 0.5 ms biphasic square-wave pulses at 15 Hz. During the TSS + FES condition, timing between the two modalities was adjusted in increments of ¼ time between pulses (16.5 ms). Results When TSS preceded FES, a larger force production was observed. We also determined several changes in muscle activation amplitude at different relative stimulus intervals, which help characterize our finding and indicate the facilitating and inhibitory effects of the modalities. Conclusions Utilizing a delay ranging from 15 to 30 ms between stimuli resulted in higher mean force generation in both the knee and ankle joints, regardless of the selected FES location (Average; knee: 112.0%, ankle: 103.1%).

Abstract
Heart rate variability biofeedback (HRV-F) is a neurocardiac self-regulation therapy that aims to regulate cardiac autonomic nervous system activity and improve cardiac balance. Despite benefits in various clinical populations, no study has reported the effects of HRV-F in adults with a spinal cord injury (SCI). This article provides an overview of a neuropsychophysiological laboratory framework and reports the impact of an HRV-F training program on two adults with chronic SCI (T1 AIS A and T3 AIS C) with different degrees of remaining cardiac autonomic function. The HRV-F intervention involved 10 weeks of face-to-face and telehealth sessions with daily HRV-F home practice. Physiological (HRV, blood pressure variability (BPV), baroreflex sensitivity (BRS)), and self-reported assessments (Fatigue Severity Scale, Generalised Anxiety Disorder Scale, Patient Health Questionnaire, Appraisal of Disability and Participation Scale, EuroQol Visual Analogue Scale) were conducted at baseline and 10 weeks. Participants also completed weekly diaries capturing mood, anxiety, pain, sleep quality, fatigue, and adverse events. Results showed some improvement in HRV, BPV, and BRS. Additionally, participants self-reported some improvements in mood, fatigue, pain, quality of life, and self-perception. A 10-week HRV-F intervention was feasible in two participants with chronic SCI, warranting further investigation into its autonomic and psychosocial effects.

Abstract
Spinal cord injury (SCI) evokes profound bladder dysfunction. Current treatments are limited by a lack of molecular data to inform novel therapeutic avenues. Previously, we showed systemic inosine treatment improved bladder function following SCI in rats. Here, we applied multi-omics analysis to explore molecular alterations in the bladder and their sensitivity to inosine following SCI. Canonical pathways regulated by SCI included those associated with protein synthesis, neuroplasticity, wound healing, and neurotransmitter degradation. Upstream regulator analysis identified MYC as a key regulator, whereas causal network analysis predicted multiple regulators of DNA damage response signaling following injury, including PARP-1. Staining for both DNA damage (γH2AX) and PARP activity (poly-ADP-ribose) markers in the bladder was increased following SCI, and attenuated in inosine-treated tissues. Proteomics analysis suggested that SCI induced changes in protein synthesis-, neuroplasticity-, and oxidative stress-associated pathways, a subset of which were shown in transcriptomics data to be inosine-sensitive. These findings provide novel insights into the molecular landscape of the bladder following SCI, and highlight a potential role for PARP inhibition to treat neurogenic bladder dysfunction.

Abstract
People with spinal cord injury (SCI) often experience secondary health conditions (SHCs), which are addressed during interdisciplinary follow-up clinics. We adapted the design of our clinic, by introducing a questionnaire concerning functioning and SHCs, additional measurements of blood pressure and saturation, and participants were seen by either a specialized nurse or rehabilitation physician. In this study, we investigated the effects of these adaptations and the experienced satisfaction of the participants. The results showed an increased number of recommendations in the adapted design, compared to the initial design. Further, the nature of the recommendations shifted from somatic issues to recommendations regarding psychosocial functioning and regarding (the use of) devices. The added measurements revealed an average high systolic blood pressure, which led to more referrals to the general practitioner. The clinical weight and pulmonary functions stayed stable over time. The current adaptations in design expanded and optimized the number and nature of recommendations regarding SHCs to participants. The questionnaire helps the participant to prepare for the clinic and the professionals to tailor their recommendations, resulting in highly satisfied participants.

Abstract
Background Individuals with a spinal cord injury (SCI) are considered higher users of antibiotics. However, to date there have been no detailed studies investigating outpatient antibiotic use in this population. Objectives (1) To describe primary care antibiotic prescribing patterns in adults with SCI rostered to a primary care physician (PCP), and (2) to identify patient or PCP factors associated with number of antibiotics prescribed and antibiotic prescription duration. Methods A retrospective cohort study using linked health administrative and electronic medical records (EMR) databases from January 1, 2013 to December 31, 2015 among 432 adults with SCI in Ontario, Canada. Negative binomial regression analyses were conducted to identify patient or physician factors associated with number of antibiotics prescribed and prescription duration. Results During the study period, 61.1% of the SCI cohort received an antibiotic prescription from their PCP. There were 59.8% of prescriptions for urinary tract infections (UTI) and 24.6% of prescriptions for fluoroquinolones. Regression analysis found catheter use was associated with increased number of antibiotics prescribed (relative risk [RR] = 3.1; 95% CI, 2.3-4.1; p < .001) and late career PCPs, compared to early-career PCPs, prescribed a significantly longer duration (RR = 1.8; 95% CI, 1.1-3.1; p = .02). Conclusion UTIs were the number one prescription indication, and fluoroquinolones were the most prescribed antibiotic. Catheter use was associated with number of antibiotics, and PCP's years of practice was associated with duration. The study provided important information about primary care antibiotic prescribing in the SCI population and found that not all individuals received frequent antibiotics prescriptions.

Abstract
Cognitive impairment is common in persons with spinal cord injury (SCI), impacting their daily functioning and rehabilitation. This study assesses the extent of self-reported cognitive failures in everyday life in persons with SCI and its relationships with objective neurocognitive measures and psychosocial factors, including depressive mood, anxiety, perceived control, and fatigue. The differences between forty-one adults with a chronic SCI and forty-one able-bodied controls were examined. The participants completed the Cognitive Failures Questionnaire (CFQ) to assess cognitive failure and neurocognitive tests assessing attention and executive functions, as well as a psychosocial assessment. The SCI group reported higher cognitive failure rates than the able-bodied group (31.7% versus 19%, p > 0.05). Objective neurocognitive tests did not significantly correlate with the CFQ scores in either group. However, the CFQ scores were positively associated with most psychosocial factors, even after controlling for covariates. The CFQ scores were significantly associated with depressive mood in persons with SCI. These findings highlight the importance of incorporating self-reported cognitive measures into neurocognitive assessments and rehabilitation planning for adults with SCI. Self-reports capture everyday cognitive challenges that objective tests may miss. Additionally, this study highlights the strong connections between cognitive failures and psychosocial issues, particularly mood disorders, emphasizing the need for comprehensive rehabilitation and psychosocial support post-SCI, addressing both cognitive and emotional wellbeing.

Using the Standing and Walking Assessment Tool at Discharge Predicts Community Outdoor Walking Capacity in Persons With Traumatic Spinal Cord Injury. Phys Ther 2023; 103:pzad106. [PMID: 37561412 PMCID: PMC10799252 DOI: 10.1093/ptj/pzad106] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Revised: 03/10/2023] [Accepted: 05/06/2023] [Indexed: 08/11/2023]
Abstract
OBJECTIVE The Standing and Walking Assessment Tool (SWAT) standardizes the timing and content of walking assessments during inpatient rehabilitation by combining 12 stages ranging from lowest to highest function (0, 0.5, 1A, 1B, 1C, 2A, 2B, 2C, 3A, 3B, 3C, and 4) with 5 standard measures: the Berg Balance Scale, the modified Timed "Up & Go" test, the Activities-specific Balance Confidence Scale, the modified 6-Minute Walk Test, and the 10-Meter Walk Test (10MWT). This study aimed to determine if the SWAT at rehabilitation discharge could predict outdoor walking capacity 1-year after discharge in people with traumatic spinal cord injury. METHODS This retrospective study used data obtained from the Rick Hansen Spinal Cord Injury Registry from 2014 to 2020. Community outdoor walking capacity was measured using the Spinal Cord Independence Measure III (SCIM III) outdoor mobility score obtained 12 (±4) months after discharge. Of 206 study participants, 90 were community nonwalkers (ie, SCIM III score 0-3), 41 were community walkers with aids (ie, SCIM III score 4-6), and 75 were independent community walkers (ie, SCIM III score 7-8). Bivariate, multivariable regression, and an area under the receiver operating characteristic curve analyses were performed. RESULTS At rehabilitation discharge, 3 significant SWAT associations were confirmed: 0-3A with community nonwalkers, 3B/higher with community walkers with and without an aid, and 4 with independent community walkers. Moreover, at discharge, a higher (Berg Balance Scale, Activities-specific Balance Confidence Scale), faster (modified Timed "Up & Go," 10MWT), or further (10MWT) SWAT measure was significantly associated with independent community walking. Multivariable analysis indicated that all SWAT measures, except the 10MWT were significant predictors of independent community walking. Furthermore, the Activities-Specific Balance Confidence Scale had the highest area under the receiver operating characteristic score (0.91), demonstrating an excellent ability to distinguish community walkers with aids from independent community walkers. CONCLUSION The SWAT stage and measures at discharge can predict community outdoor walking capacity in persons with traumatic spinal cord injury. Notably, a patient's confidence in performing activities plays an important part in achieving walking ability in the community. IMPACT The discharge SWAT is useful to optimize discharge planning.

Abstract
INTRODUCTION Neurogenic bladder is a common complication after spinal cord injury (SCI) that carries substantial burdens on the inflicted individual. The objective of this study is to build a prediction model for neurogenic bladder recovery 1 year after traumatic SCI. METHODS We queried the National Spinal Cord Injury Model Systems database for patients with traumatic SCI who had neurogenic bladder at the time of injury. The primary outcome of interest was the complete recovery of bladder function at 1 year. Multiple imputations were performed to generate replacement values for missing data, and the final imputed data were used for our analysis. A multivariable odds logistic regression model was developed for complete bladder recovery at 1 year. RESULTS We identified a total of 2515 patients with abnormal bladder function at baseline who had an annual follow-up. A total of 417 patients (16.6%) recovered bladder function in 1 year. Predictors of complete bladder recovery included the following baseline parameters: sacral sensation, American Spinal Injury Association (ASIA) impairment score, bowel function at baseline, voluntary sphincter contraction, anal sensation, S1 motor scores, and the number of days in the rehabilitation facility. The model performed with a discriminative capacity of 90.5%. CONCLUSIONS We developed a prediction model for the probability of complete bladder recovery 1 year after SCI. The model performed with a high discriminative capacity. This prediction model demonstrates potential utility in the counseling, research allocation, and management of individuals with SCI.

Abstract
Central nervous system (CNS) diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), glioblastoma (GBM), and peripheral nerve injury have been documented as incurable diseases, which lead to serious impacts on human health especially prevalent in the aging population worldwide. Most of the treatment strategies fail due to low efficacy, toxicity, and poor brain penetration. Recently, advancements in nanotechnology have helped alleviate the challenges associated with the application of cell membrane-based nanomaterials against CNS diseases. In the following review, the existing types of cell membrane-based nanomaterials systems which have improved therapeutic efficacy for CNS diseases would be described. A summary of recent progress in the incorporation of nanomaterials in cell membrane-based production, separation, and analysis will be provided. Addition to, challenges relate to large-scale manufacturing of cell membrane-based nanomaterials and future clinical trial of such platforms will be discussed.

Abstract
Spasticity is a chronic neurological complication associated with spinal cord injury (SCI), characterized by increased muscle tone and stiffness. A physiological sign of spasticity is hyperreflexia, evident by the loss of evoked rate-dependent depression (RDD) in the H-reflex. Although previous work has shown that SCI-induced astrogliosis contributes to hyperexcitability disorders, including neuropathic pain and spasticity, it is unclear how reactive astrocytes can modulate synaptic transmission within the injured spinal cord. To study astrocytes' role in post-SCI hyperreflexia, we examined glutamate transporter-1 (GLT-1) and postsynaptic density protein 95 (PSD-95) proteins in astrocytes and neurons, respectively, within the ventral horn (lamina IX) below the level of injury (spinal segment L4-5). The close juxtaposition of GLT-1 and PSD-95 markers is a molecular correlate of tripartite synapses and is thought to be a key element in the astrocyte-induced plasticity of neuronal synapses. Our study compared animals with and without SCI-induced hyperreflexia and spasticity and investigated potential synaptic abnormalities associated with astrocyte involvement. As expected, 4 wk after SCI, we observed a loss in evoked H-reflex RDD in hindlimb electromyogram recordings, i.e., hyperreflexia, in contrast to uninjured sham. Importantly, our main findings show a significant increase in the presence of GLT-1-PSD-95 tripartite synapses in the ventral spinal cord motor regions of animals exhibiting SCI-induced hyperreflexia. Taken together, our study suggests the involvement of astrocyte-neuron synaptic complexes in the plasticity-driven progression of chronic spasticity.NEW & NOTEWORTHY The role of astrocytes in H-reflex hyperexcitability following SCI remains understudied. Our findings establish a relationship between GLT-1 expression, its proximity to neuronal PSD-95 in the spinal cord ventral horn, and the loss of H-reflex RDD, i.e., hyperreflexia. Our findings provide a new perspective on synaptic alterations and the development of SCI-related spasticity.

Abstract
PURPOSE Improving quality of life (QoL) is a major goal of rehabilitation following spinal cord injury (SCI). However, people with disabilities in resource constrained contexts have limited access to rehabilitation and poorer health outcomes, including QoL. There is a paucity of qualitative research on the experiences of persons with SCI involved in rehabilitation programmes in low-middle income countries. This study aimed to assess participants' perceptions of the benefits of a 24-week SCI rehabilitation programme delivered as part of a pilot randomized controlled trial (RCT) in South Africa. MATERIALS AND METHODS Sixteen participants, with chronic motor-incomplete tetraplegia, were enrolled in a two-arm pilot RCT involving robotic locomotor training, a novel technology, and standard activity-based training (Pan African Clinical Trial Registry (PACTR201608001647143)). Data were collected via in-depth interviews and analysed using thematic analysis. RESULTS Participants described several improvements in QoL, including enhanced functional independence; reduced secondary complications; and improved psychosocial and emotional well-being. CONCLUSIONS The holistic approach to rehabilitation calls for the involvement of individuals' views about what matters to them to inform clinical practice and to highlight the role that physical activity and the perceived successes play in shaping the lived experiences after SCI.

Abstract
Cervical spine fractures represent a significant healthcare challenge, necessitating accurate detection for appropriate management and improved patient outcomes. This study aims to develop a machine learning-based model utilizing a computed tomography (CT) image dataset to detect and classify cervical spine fractures. Leveraging a large dataset of 4,050 CT images obtained from the Radiological Society of North America (RSNA) Cervical Spine Fracture dataset, we evaluate the potential of machine learning and deep learning algorithms in achieving accurate and reliable cervical spine fracture detection. The model demonstrates outstanding performance, achieving an average precision of 1 and 100% precision, recall, sensitivity, specificity, and accuracy values. These exceptional results highlight the potential of machine learning algorithms to enhance clinical decision-making and facilitate prompt treatment initiation for cervical spine fractures. However, further research and validation efforts are warranted to assess the model's generalizability across diverse populations and real-world clinical settings, ultimately contributing to improved patient outcomes in cervical spine fracture cases.

Abstract
Objective To compare the incidence of and adjusted hazards for serious and life-threatening morbidities among adults with traumatic spinal cord injury (TSCI) with and without type 2 diabetes (T2D). Participants and Methods A retrospective longitudinal cohort study was conducted from September 1, 2022 to February 2, 2023, among privately insured beneficiaries if they had an International Classification of Diseases, 9th Revision or 10th Revision, Clinical Modification diagnostic code for TSCI (n=9081). Incidence estimates of serious and life-threatening morbidities, and more common secondary and long-term health conditions, were compared at 5 years of enrollment. Survival models were used to quantify unadjusted and adjusted hazard ratios for serious and life-threatening morbidities. Results Adults living with TSCI and T2D had a higher incidence of all of the morbidities assessed as compared with nondiabetic adults with TSCI. Fully adjusted survival models reported that adults with TSCI and T2D had a greater hazard for most of the serious and life-threatening conditions assessed, including sepsis (hazard ratio [HR]: 1.65), myocardial infarction (HR: 1.63), osteomyelitis (HR: 1.9), and stroke or transient ischemic attack (HR: 1.59). Rates for comorbid and secondary conditions were higher for individuals with TSCI and T2D, such as pressure sores, urinary tract infections, and depression, even after controlling for sociodemographic and comorbid conditions. Conclusion Adults living with TSCI and T2D have a significantly higher incidence of and risk of developing serious and life-threatening morbidities as compared with nondiabetic adults with TSCI.

Abstract
OBJECTIVES Spinal cord injury (SCI) results in mild to severe functional limitations, decreasing a person's ability to perform activities of daily living. This study aims to identify the influence of SCI characteristics and self-efficacy on functional limitations, controlling for sociodemographic factors. METHODS Participants for this cross-sectional descriptive study included 272 persons with SCI. The participants completed questionnaires on sociodemographic information, secondary physical conditions, self-efficacy, and functional limitations, using an online Qualtrics Survey. Multiple hierarchical regression analysis was performed to test the hypothesis. RESULTS Participants reported higher functional limitations on dressing the lower body and managing their bowels compared to other activities of daily living. The sociodemographics, injury characteristics, and self-efficacy collectively accounted for 66% variance in functional limitations. A higher level of secondary physical conditions and tetraplegia injury contributed to higher functional limitations. As hypothesized, greater self-efficacy significantly contributed to low functional limitations above and beyond sociodemographic and SCI-related variables. DISCUSSION Functional limitations following SCI are a pervasive challange in persons with SCI. Early recognition and management of secondary conditions and implementation of psychological interventions to strengthen self-efficacy in performing activities and managing secondary complications could potentially enhance functional independence and, ultimately, quality of life in this population.

Assessing walking ability using a robotic gait trainer: opportunities and limitations of assist-as-needed control in spinal cord injury. J Neuroeng Rehabil 2023; 20:121.

Abstract
BACKGROUND Walking impairments are a common consequence of neurological disorders and are assessed with clinical scores that suffer from several limitations. Robot-assisted locomotor training is becoming an established clinical practice. Besides training, these devices could be used for assessing walking ability in a controlled environment. Here, we propose an adaptive assist-as-needed (AAN) control for a treadmill-based robotic exoskeleton, the Lokomat, that reduces the support of the device (body weight support and impedance of the robotic joints) based on the ability of the patient to follow a gait pattern displayed on screen. We hypothesize that the converged values of robotic support provide valid and reliable information about individuals' walking ability. METHODS Fifteen participants with spinal cord injury and twelve controls used the AAN software in the Lokomat twice within a week and were assessed using clinical scores (10MWT, TUG). We used a regression method to identify the robotic measure that could provide the most relevant information about walking ability and determined the test-retest reliability. We also checked whether this result could be extrapolated to non-ambulatory and to unimpaired subjects. RESULTS The AAN controller could be used in patients with different injury severity levels. A linear model based on one variable (robotic knee stiffness at terminal swing) could explain 74% of the variance in the 10MWT and 61% in the TUG in ambulatory patients and showed good relative reliability but poor absolute reliability. Adding the variable 'maximum hip flexor torque' to the model increased the explained variance above 85%. This did not extend to non-ambulatory nor to able-bodied individuals, where variables related to stance phase and to push-off phase seem more relevant. CONCLUSIONS The novel AAN software for the Lokomat can be used to quantify the support required by a patient while performing robotic gait training. The adaptive software might enable more challenging training conditions tuned to the ability of the individuals. While the current implementation is not ready for assessment in clinical practice, we could demonstrate that this approach is safe, and it could be integrated as assist-as-needed training, rather than as assessment.

Abstract
STUDY DESIGN A retrospective study. OBJECTIVES The quality of care (QoC) for spinal column/cord injury patients is a major health care concern. This study aimed to implement the QoC assessment tool (QoCAT) in the National Spinal Cord/Column Injury Registry of Iran (NSCIR-IR) to define the current state of pre- and post-hospital QoC of individuals with Traumatic Spinal Column and Spinal Cord Injuries (TSC/SCIs). METHODS The QoCAT, previously developed by our team to measure the QoC in patients with TSC/SCIs, was implemented in the NSCIR-IR. The pre-hospital QoC was evaluated through a retrospective analysis of NSCIR-IR registry data. Telephone interviews and follow-ups of patients with SCI evaluated the QoC in the post-hospital phase. RESULTS In the pre-hospital phase, cervical collars and immobilization were implemented in 46.4% and 48.5% of the cases, respectively. Transport time from the scene to the hospital was documented as <1 hour and <8 hours in 33.4% and 93.9% of the patients, respectively. Post-hospital indicators in patients with SCI revealed a first-year mortality rate of 12.5% (20/160), a high incidence of secondary complications, reduced access to electrical wheelchairs (4.2%) and modified cars (7.7%), and low employment rate (21.4%). CONCLUSION These findings revealed a significant delay in transport time to the first care facilities, low use of immobilization equipment indicating low pre-hospital QoC. Further, the high incidence of secondary complications, low employment rate, and low access to electrical wheelchairs and modified cars indicate lower post-hospital QoC in patients with SCI. These findings imply the need for further planning to improve the QoC for patients with TSC/SCIs.

Abstract
Background and Objectives: This study aimed to evaluate the effectiveness of a wheelchair skills training program (WSTP) in improving sitting balance and pulmonary function in patients with chronic tetraplegia resulting from cervical spinal cord injury (cSCI). Materials and Methods: Twenty-four patients were randomly divided into WSTP and control groups. The WSTP group participated in the WSTP for eight weeks, while the control group underwent conventional physical therapy for the same eight-week period. Sitting balance was evaluated using the activity-based balance level evaluation (ABLE) scale, and pulmonary function was evaluated using forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and peak expiratory flow (PEF). Results: The WSTP group showed significant improvements in both sitting balance and pulmonary function during the intervention period (p < 0.05), whereas the control group did not show any significant changes. A strong positive correlation was found between ABLE scores and all three pulmonary function parameters across all time points. Conclusions: Our results suggest that the WSTP significantly improves sitting balance and specific aspects of lung function in patients with tetraplegia.

Abstract
OBJECTIVE Veterans with spinal cord injuries and disorders (SCI/D) utilizing Veterans Affairs healthcare facilities are also Medicare eligible. Use of multiple health care systems potentially duplicates or fragments care in this population; yet little is known about those using multiple systems. This study describes dual use of services paid for by VA and Medicare among Veterans with SCI/D. DESIGN Retrospective, cross-sectional, observational study. PARTICIPANTS Veterans with SCI/D (n = 13,902) who received healthcare services within the VA SCI System of Care and were eligible for or enrolled in Medicare in 2011. INTERVENTIONS N/A. OUTCOME MEASURES Patient characteristics, average number of visits and patient level frequencies of reasons for visits were determined for individuals within healthcare utilization (VA only, Medicare only, or dual VA/Medicare) groups. Multinomial logistic regression analyses were used to investigate associations of patient variables on dual use. RESULTS 65.3% of Veterans with SCI/D were VA only users for outpatient encounters, 4.4% had encounters paid for by Medicare only, and 30.3% were dual users. Veterans were less likely to be VA only users if they were older than 69 and if they had been injured for greater than ten years. African American Veterans with SCI (compared to white) were more likely to be VA only users. CONCLUSION A substantial number (∼30%) of Veterans with SCI/D are dual users. These numbers highlight the importance of improved strategies to coordinate care and increase health information sharing across systems.

Abstract
Objective To assess the frequency of suicidal ideation (SI) among individuals with chronic spinal cord injury (SCI) and to identify risk factors associated with SI. Design Cross-sectional. Setting Community setting. Participants Two hundred and forty-six individuals with chronic SCI participating in the Spinal Cord Injury Model Systems at a Level 1 Trauma center. Interventions Not applicable. Main Outcome Measure SI, as assessed by question 9 of the Patient Health Questionnaire-9. Results Twenty-seven (11.0%) participants endorsed SI; 6 (22.2%) of whom endorsed active SI with a plan of self-harm. Participants who endorsed SI had significantly higher depressive symptoms, lower resilience, and lower satisfaction with life (all Ps<.001). They also had lower perceived health (P<.001), Craig Handicap Assessment & Reporting Technique Short Form (CHART-SF) physical independence (P=.013), and Spinal Cord Injury - Functional Index with Assistive Technology domains of basic mobility (P=.003), self-care (P=.042), and fine motor skills (P=.035). However, participants who endorsed SI were not significantly different in re-hospitalization rates and in other domains of CHART-SF and SCI-AT. Logistic regression, with a forward selection procedure, was used to identify significant predictors of endorsing SI in the context of multiple associated variables. Depressive symptoms (odds ratio [OR]=1.18, P=.020), resilience (OR=0.85, P=.003), and physical independence (OR=0.98, P=.019) remained significant predictors of SI. Conclusion Study findings suggest higher levels of SI among people with SCI, a substantial proportion of whom have active SI. Individuals with SCI who endorse SI have greater burden of poor physical and mental health, as well as poorer functional status and adaptation. Interventions targeting multiple dimensions of quality of life may help reduce risk of SI and suicide among individuals with SCI.

Abstract
Spinal cord injury (SCI) is a sudden onset of disruption to the spinal neural tissue, leading to loss of motor control and sensory function of the body. Oxidative stress is considered a hallmark in SCI followed by a series of events, including inflammation and cellular apoptosis. Melatonin was originally discovered as a hormone produced by the pineal gland. The subcellular localization of melatonin has been identified in mitochondria, exhibiting specific onsite protection to excess mitochondrial reactive oxygen species and working as an antioxidant in diseases. The recent discovery regarding the molecular basis of ligand selectivity for melatonin receptors and the constant efforts on finding synthetic melatonin alternatives have drawn researchers' attention back to melatonin. This review outlines the application of melatonin in SCI, including 1) the relationship between the melatonin rhythm and SCI in clinic; 2) the neuroprotective role of melatonin in experimental traumatic and ischemia/reperfusion SCI, i.e., exhibiting anti-oxidative, anti-inflammatory, and anti-apoptosis effects, facilitating the integrity of the blood-spinal cord barrier, ameliorating edema, preventing neural death, reducing scar formation, and promoting axon regeneration and neuroplasticity; 3) protecting gut microbiota and peripheral organs; 4) synergizing with drugs, rehabilitation training, stem cell therapy, and biomedical material engineering; and 5) the potential side effects. This comprehensive review provides new insights on melatonin as a natural antioxidant therapy in facilitating rehabilitation in SCI.

Abstract
The drawbacks of stem cell (SC) therapies have led to investigations of SC conditioned medium (CM) instead of SC transplantation in the repair of spinal cord injury (SCI). However, the effectiveness of CM in comparison with cell transplantation in SCI models remain an open and intriguing question. The focus of this review was to survey existing publications addressing this comparison. The review included articles from electronic databases Medline, Embase, Scopus, and Web of Science that included comparisons of the effects of CM versus SC transplantation and versus controls on locomotion after SCI. The search yielded 5 studies and 6 experiments. The results indicated that there was insufficient evidence to conclude that treatment with CM and source cells were equally effective (SMD = 0.12; 95% CI = -0.36 to 0.59; p = 0.07). Regarding investigations of separate effects of SCs versus CM, there currently is limited evidence on efficacy in SCI models. This highlights a notable concern affecting this field. Thus, we identified critical knowledge gaps concerning comparisons of the efficacy of therapeutic application of SC and their derived CM on functional recovery following SCI.

Abstract
Unlike adult mammals, zebrafish regenerate spinal cord tissue and recover locomotor ability after a paralyzing injury. Here, we find that ependymal cells in zebrafish spinal cords produce the neurogenic factor Hb-egfa upon transection injury. Animals with hb-egfa mutations display defective swim capacity, axon crossing, and tissue bridging after spinal cord transection, associated with disrupted indicators of neuron production. Local recombinant human HB-EGF delivery alters ependymal cell cycling and tissue bridging, enhancing functional regeneration. Epigenetic profiling reveals a tissue regeneration enhancer element (TREE) linked to hb-egfa that directs gene expression in spinal cord injuries. Systemically delivered recombinant AAVs containing this zebrafish TREE target gene expression to crush injuries of neonatal, but not adult, murine spinal cords. Moreover, enhancer-based HB-EGF delivery by AAV administration improves axon densities after crush injury in neonatal cords. Our results identify Hb-egf as a neurogenic factor necessary for innate spinal cord regeneration and suggest strategies to improve spinal cord repair in mammals.

Risk constellation of hospital acquired pressure injuries in patients with a spinal cord injury/ disorder - focus on time since spinal cord injury/ disorder and patients' age. Spinal Cord 2023; 61:453-459. [PMID: 37407644 DOI: 10.1038/s41393-023-00910-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2022] [Revised: 06/20/2023] [Accepted: 06/26/2023] [Indexed: 07/07/2023]
Abstract
STUDY DESIGN Prospective cohort study. OBJECTIVES The aim of this study was to evaluate how time since spinal cord injury/disorder (SCI/D) and patients' age influence risk constellation for hospital acquired pressure injuries (HAPI) in patients with a SCI/D. SETTING Acute care and rehabilitation clinic specialized in SCI/D. METHODS We collected patients' characteristics and 85 risk factors for HAPI development in adults with SCI/D with at least one HAPI during their inpatient stay between August 2018 and December 2019. We analyzed patients' characteristics and HAPI risk factors using descriptive statistics according to time since SCI/D ( < 1 year, 1-15 years, > 15 years) and patients' age (18-35 years, 35-65 years, > 65 years). RESULTS We identified 182 HAPI in 96 patients. Comparing patients with SCI/D < 1 year with the other groups, autonomic dysreflexia (p < 0.001), abnormal body temperature (p = 0.001), hypertensive episode (p = 0.005), and pneumonia (p < 0.001) occurred more frequently; mean hemoglobin (p < 0.001), albumin (p = 0.002) and vitamin D levels (p = 0.013) were significantly lower, and patients with time since SCI/D < 1 year scored fewer points (10-12) on the Braden Scale (p < 0.001). Comparing groups per patients' age, only the SCIPUS score was higher in patients > 65 years compared to the other two groups (p = 0.002). CONCLUSIONS Different risk factor constellation seem to be underlying HAPI development with more differences in patients time since SCI/D than patients' age. Awareness of these differences in risk factor constellation depending on time since SCI/D in these patients might lead to different HAPI prevention strategies. SPONSORSHIP The study team didn't receive any additional sponsorship.

Abstract
The use of the cervical collar to support the head and neck is inevitable in many patients with head and spinal cord injuries. One of the consequences of using this instrument is the development of pressure injuries. Therefore, in this review study, the incidence of as well as the risk factors for cervical collar-related pressure injury in this group of patients was evaluated. The current study is a scoping review conducted in 2022. Five scientific databases (PubMed, Scopus, Web of Science, ProQuest, and CINAHL), as well as Google Scholar, were searched for relevant studies published from 1990 to 2022 using the following keywords: trauma, spinal cord injury, head injury, head trauma, collar, cervical collar, cervical immobilization, risk factors, incidence, pressure injury, pressure ulcer, and bed sore. The search was performed independently by two researchers. Articles from the initial search were first recorded in special tables, and then, were reviewed and analyzed separately by two researchers. After extraction, information from each article was entered into a special table categorized by year, country, study design, study population, the incidence of cervical collar-related pressure injury, risk factors for cervical collar-related pressure injury, and grades of pressure injury. Of the 10 articles, 6 were retrospective cohort studies, 3 were cross-sectional descriptive studies, and 1 was a case report study. In terms of the study population, one study was conducted on pediatric patients, one was conducted on elderly patients, and eight were conducted on adults with head and neck trauma. In eight articles, the incidence of cervical collar-related pressure injury was reported. The reported incidence varied between 1.1% and 78.4%. In eight articles, risk factors for cervical collar-related pressure injury were reported. The most common risk factors were duration of cervical collar use, hospitalization in intensive care units, low level of consciousness, and longer hospital stay. The current review study showed that a significant percentage of head and neck trauma patients for whom cervical collar is used suffer from different grades of pressure injuries. Hence, healthcare providers should consider this issue when caring for this group of patients and take the necessary preventive measures in this regard. It should be noted that previous studies in this field had significant limitations, and thereby, it is strongly recommended to conduct further studies with a stronger methodology.

Abstract
Many people with spinal cord injury (SCI) develop chronic pain, including neuropathic pain. Unfortunately, current treatments for this condition are often inadequate because SCI-associated neuropathic pain is complex and depends on various underlying mechanisms and contributing factors. Multimodal treatment strategies including but not limited to pharmacological treatments, physical rehabilitation, cognitive training, and pain education may be best suited to manage pain in this population. In this study, we developed an educational resource named the SeePain based on published pain literature, and direct stakeholder input, including people living with SCI and chronic pain, their significant others, and healthcare providers with expertise in SCI. The SeePain was then 1) systematically evaluated by stakeholders regarding its content, comprehensibility, and format using qualitative interviews and thematic analysis, and 2) modified based on their perspectives. The final resource is a comprehensive guide for people with SCI and their significant others or family members that is intended to increase health literacy and facilitate communication between SCI consumers and their healthcare providers. Future work will quantitatively validate the SeePain in a large SCI sample.

Abstract
INTRODUCTION Spinal cord injury (SCI) can lead to severe neurological dysfunction. Despite scientific and medical advances, clinically effective regenerative therapies including stem cells are lacking for SCI. AREAS COVERED This paper discusses translational challenges related to the safe, effective use of stem cells for SCI, with a focus on mesenchymal stem cells (MSCs), neural stem cells (NSCs), Schwann cells (SCs), olfactory ensheathing cells (OECs), oligodendrocyte precursor cells (OPCs), embryonic stem cells (ESCs), and induced pluripotent stem cells (iPSCs). We discuss approaches to enhance the efficacy of cell-based strategies by i) addressing patient heterogeneity and enhancing patient selection; ii) selecting cell type, cell source, cell developmental stage, and delivery technique; iii) enhancing graft integration and mitigating immune-mediated graft rejection; and iv) ensuring availability of cells. Additionally, we review strategies to optimize outcomes including combinatorial use of rehabilitation and discuss ways to mitigate potential risks of tumor formation associated with stem cell-based strategies. EXPERT OPINION Basic science research will drive translational advances to develop stem cell-based therapies for SCI. Genetic, serological, and imaging biomarkers may enable individualization of cell-based treatments. Moreover, combinatorial strategies will be required to enhance graft survival, migration and functional integration, to enable precision-based intervention.

Abstract
STUDY DESIGN Cross-sectional study. OBJECTIVES To determine the Quality of Life (QOL) in individuals with traumatic Spinal Cord Injury (SCI) of thoracolumbar region in Indian population, the factors affecting QOL and to compare this to other SCI populations. SETTING Tertiary level hospital in low-middle income country. METHODS 93 individuals with SCI of minimum 1 year duration since injury were included in the study. Baseline demographics, socioeconomic parameters, and incidence of complications were ascertained. World Health Organisation Quality of Life-BREF (WHOQOL-BREF) score was used for measurement of QOL and was then compared to healthy Indian population and other SCI studies. Subgroup analysis was done to find out impact of variables on different domains of WHOQOL-BREF. RESULTS The median (IQR) age of the study participants was 35 (25, 45) with a male predominance. The median (IQR) duration since injury in the study population was 50 (26, 70) months. Lowest mean (SD) score was observed in the psychological domain -50.3 (12.1) and comparison to healthy Indian and high-income SCI populations revealed drastically decreased scores across all domains (p < 0.01). Employed individuals and housewives had significantly higher scores across all domains than unemployed individuals (p < 0.05). American Spinal Injury Association Impairment Scale (AIS) grade, socioeconomic status, pain and presence of complications all had significant impact on domain scores (p < 0.05). Multiple regression analysis revealed that mobilisation status and pain had the greatest effect on QOL. CONCLUSION Individuals with SCI have low QOL scores as compared to general Indian population as well as SCI individuals from a high resource setting. Pain and dependent mobilisation were found to be most significant predictors of poor WHOQOL-BREF domain scores. Housewives were found to have domain scores comparable to employed individuals. Presence of complications negatively impacts QOL.

Effects of behaviour change interventions on physical activity in people with spinal cord injury: A systematic review and meta-analysis. PSYCHOLOGY OF SPORT AND EXERCISE 2023; 67:102408.

Abstract
OBJECTIVES This review investigated the effectiveness of behaviour-change interventions to improve physical activity (PA) participation in individuals with a spinal cord injury. Additionally, the review sought to analyse the change in PA behaviour that might be expected by utilising behaviour change in PA interventions and what specific intervention characteristics, application of behaviour change theories, and behaviour change techniques are most efficacious. METHODS The protocol was prospectively registered on PROSPERO: CRD42021252744, and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were followed in this review. Eight databases were comprehensively searched using a well-defined strategy developed in collaboration with an academic liaison librarian. Randomised, non-randomised controlled, and non-controlled studies were included in this review; however, controlled and non-controlled studies were analysed separately. Studies were included if participants were older than 16 years and had an SCI of any cause, level or severity, regardless of the time since injury. The behaviour change technique taxonomy version 1 was used to code the intervention characteristics for behaviour modification. The combined effects across studies were pooled in a meta-analysis, and the risk of bias was assessed using the Cochrane Risk of Bias 2 tool. RESULTS The search retrieved 10,155 titles and abstracts. After duplicate removal and screening against the eligibility criteria, 23 studies were included. The overall effect estimate of the change in PA participation in the controlled trials post-intervention was medium (d = 0.50, 95% CI = 0.31-0.70) in favour of behaviour-targeted interventions. The mean difference in PA volume between pre- and post-intervention was an increase of 22 minutes per week (95% CI = 5.96-38.90). Interventions that provided practical support (d = 0.81, 95% CI = 0.46-1.16), which were individualised (d = 0.62, 95% CI = 0.34-0.90) and that utilised monitoring (d = 0.59, 95% CI = 0.34-0.83) had a greater effect on change to PA than those that were group-based and did not utilise those specific techniques. CONCLUSIONS Interventions that target behaviour change to increase PA in people with SCI appear effective. Utilising behaviour change frameworks and specific behaviour change techniques augments PA uptake and levels, and interventions aimed at improving PA in people with SCI should incorporate a behaviour modification component. More research is needed on the isolated effect of intervention structure parameters and specific behaviour change techniques.

Abstract
Spinal cord injury (SCI) is a devastating and disabling medical condition generally caused by a traumatic event (primary injury). This initial trauma is accompanied by a set of biological mechanisms directed to ameliorate neural damage but also exacerbate initial damage (secondary injury). The alterations that occur in the spinal cord have not only local but also systemic consequences and virtually all organs and tissues of the body incur important changes after SCI, explaining the progression and detrimental consequences related to this condition. Psychoneuroimmunoendocrinology (PNIE) is a growing area of research aiming to integrate and explore the interactions among the different systems that compose the human organism, considering the mind and the body as a whole. The initial traumatic event and the consequent neurological disruption trigger immune, endocrine, and multisystem dysfunction, which in turn affect the patient's psyche and well-being. In the present review, we will explore the most important local and systemic consequences of SCI from a PNIE perspective, defining the changes occurring in each system and how all these mechanisms are interconnected. Finally, potential clinical approaches derived from this knowledge will also be collectively presented with the aim to develop integrative therapies to maximize the clinical management of these patients.
