OBJECTIVE The physiological mechanisms underlying the recovery of motor function after cervical spondylotic myelopathy (CSM) surgery are poorly understood. Neuronal plasticity allows neurons to compensate for injury and disease and to adjust their activities in response to new situations or changes in their environment. Cortical reorganization as well as improvement in corticospinal conduction happens during motor recovery after stroke and spinal cord injury. In this study the authors aimed to understand the cortical changes that occur due to CSM and following CSM surgery and to correlate these changes with functional recovery by using blood oxygen level–dependent (BOLD) functional MRI (fMRI). METHODS Twenty-two patients having symptoms related to cervical cord compression due to spondylotic changes along with 12 age- and sex-matched healthy controls were included in this study. Patients underwent cervical spine MRI and BOLD fMRI at 1 month before surgery (baseline) and 6 months after surgery. RESULTS Five patients were excluded from analysis because of technical problems; thus, 17 patients made up the study cohort. The mean overall modified Japanese Orthopaedic Association score improved in patients following surgery. Mean upper-extremity, lower-extremity, and sensory scores improved significantly. In the preoperative patient group the volume of activation (VOA) was significantly higher than that in controls. The VOA after surgery was reduced as compared with that before surgery, although it remained higher than that in the control group. In the preoperative patient group, activations were noted only in the left precentral gyrus (PrCG). In the postoperative group, activations were seen in the left postcentral gyrus (PoCG), as well as the PrCG and premotor and supplementary motor cortices. In postoperative group, the VOA was higher in both the PrCG and PoCG as compared with those in the control group. CONCLUSIONS There is over-recruitment of sensorimotor cortices during nondexterous relative to dexterous movements before surgery. After surgery, there was recruitment of other cortical areas such as the PoCG and premotor and supplementary motor cortices, which correlated with improvement in dexterity, but activation in these areas was greater than that found in controls. The results show that improvement in dexterity and finer movements of the upper limbs is associated with recruitment areas other than the premotor cortex to compensate for the damage in the cervical spinal cord.

Object This study aimed to determine the age- and sex-specific incidence of cervical spondylotic myelopathy (CSM) and its associated risk of causing subsequent spinal cord injury (SCI). Methods Using the National Health Insurance Research Database (NHIRD), a 12-year nationwide database in Taiwan, this retrospective cohort study analyzed the incidence of hospitalization caused by CSM. All patients diagnosed with and admitted for CSM were identified during the study period. The CSM patients were divided into 2 groups, a control group and an operated group. An incidence density method was used to estimate age- and sex-specific incidence rates of CSM. The Kaplan-Meier method and Cox regression analyses were performed to compare the risk of SCI between the 2 groups. Results From 1998 to 2009, covering 349.5 million person-years, 14,140 patients were hospitalized for CSM. The overall incidence of CSM-related hospitalization was 4.04 per 100,000 person-years. Specifically, males and older persons had a higher incidence rate of CSM. During the follow-up of these patients for 13,461 person-years, a total of 166 patients were diagnosed with SCI. The incidence of SCI was higher in the control group than the operated group (13.9 vs 9.4 per 1000 person-years, respectively). During the follow-up, SCI was more likely to occur in CSM patients who were treated conservatively (crude HR 1.48, p = 0.023; adjusted HR 1.57, p = 0.011) than in those who underwent surgery for CSM. Conclusions In a national cohort of eastern Asia, the incidence of CSM-caused hospitalization was 4.04 per 100,000 person-years, with higher incidences observed in older and male patients. Subsequent SCI was more likely to develop in patients who received nonoperative management than in those who underwent surgery. Therefore, patients with CSM managed without surgery should be cautioned about SCI. However, further investigations are still required to clarify the risks and complications associated with surgery for CSM.

In this work, we studied the pharmacological activity of zinc and magnesium salts of 2-aminoethanesulfonic acid in white non-linear male rats with amyotrophic lateral sclerosis, which was modeled by neurotoxicantsimplication into the pelvic part of spinal cord. After the reproduction of the pathology in animals, the indices of motor activity were recorded in the Rotarod test, and morphological studies of spinal cord sections stained according to Nisl in the Belshovsky modification were carried out. It was shown that the magnesium salt of 2-aminoethanesulfonic acid (compound LHT-317) to a greater extent reduces the development of motor disorders in experimental animals compared with the control group on the 4th day of observation. The course of intravenous administration of the studied compounds of 2-aminoethanesulfonic acid did not inhibit morphological changes in the spinal cord that develop in degenerative-dystrophic pathology of the central nervous system: connections. Moreover, if, against the background of treatment with zinc salt, the total area of motor zones in animals of the experimental group exceeded that of control rats, then the number of motoneurons did not differ from the control.

Exercise training is a traditional method to maximize remaining function in patients with spinal cord injury (SCI), but the exact mechanism by which exercise promotes recovery after SCI has not been identified; whether exercise truly has a beneficial effect on SCI also remains unclear. Previously, we showed that epigenetic changes in the brain motor cortex occur after SCI and that a treatment leading to epigenetic modulation effectively promotes functional recovery after SCI. We aimed to determine how exercise induces functional improvement in rats subjected to SCI and whether epigenetic changes are engaged in the effects of exercise. A spinal cord contusion model was established in rats, which were then subjected to treadmill exercise for 12 weeks. We found that the size of the lesion cavity and the number of macrophages were decreased more in the exercise group than in the control group after 12 weeks of injury. Immunofluorescence and DNA dot blot analysis revealed that levels of 5-methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC) in the brain motor cortex were increased after exercise. Accordingly, the expression of ten-eleven translocation (Tet) family members (Tet1, Tet2, and Tet3) in the brain motor cortex also elevated. However, no macrophage polarization was induced by exercise. Locomotor function, including Basso, Beattie, and Bresnahan (BBB) and ladder scores, also improved in the exercise group compared to the control group. We concluded that treadmill exercise facilitates functional recovery in rats with SCI, and mechanistically epigenetic changes in the brain motor cortex may contribute to exercise-induced improvements.

ABSTRACT Background Pressure injuries (PrI) are serious complications for many with spinal cord injury (SCI), significantly burdening health care systems, in particular the Veterans Health Administration. Clinical practice guidelines (CPG) provide recommendations. However, many risk factors span multiple domains. Effective prioritization of CPG recommendations has been identified as a need. Bioinformatics facilitates clinical decision support for complex challenges. The Veteran’s Administration Informatics and Computing Infrastructure provides access to electronic health record (EHR) data for all Veterans Health Administration health care encounters. The overall study objective was to expand our prototype structural model of environmental, social, and clinical factors and develop the foundation for resource which will provide weighted systemic insight into PrI risk in veterans with SCI. Methods The SCI PrI Resource (SCI-PIR) includes three integrated modules: (1) the SCIPUDSphere multidomain database of veterans’ EHR data extracted from October 2010 to September 2015 for ICD-9-CM coding consistency together with tissue health profiles, (2) the Spinal Cord Injury Pressure Ulcer and Deep Tissue Injury Ontology (SCIPUDO) developed from the cohort’s free text clinical note (Text Integration Utility) notes, and (3) the clinical user interface for direct SCI-PIR query. Results The SCI-PIR contains relevant EHR data for a study cohort of 36,626 veterans with SCI, representing 10% to 14% of the U.S. population with SCI. Extracted datasets include SCI diagnostics, demographics, comorbidities, rurality, medications, and laboratory tests. Many terminology variations for non-coded input data were found. SCIPUDO facilitates robust information extraction from over six million Text Integration Utility notes annually for the study cohort. Visual widgets in the clinical user interface can be directly populated with SCIPUDO terms, allowing patient-specific query construction. Conclusion The SCI-PIR contains valuable clinical data based on CPG-identified risk factors, providing a basis for personalized PrI risk management following SCI. Understanding the relative impact of risk factors supports PrI management for veterans with SCI. Personalized interactive programs can enhance best practices by decreasing both initial PrI formation and readmission rates due to PrI recurrence for veterans with SCI.

AbstractNeural stem cell (NSCs) transplantation has been one of the hot topics in the repair of spinal cord injury (SCI). Fibroblast growth factor (FGF) is considered a promising nerve injury therapy after SCI. However, owing to a hostile hypoxia condition in SCI, there remains a challenging issue in implementing these tactics to repair SCI. In this report, we used adeno-associated virus 2 (AAV2), a prototype AAV used in clinical trials for human neuron disorders, basic FGF (bFGF) gene under the regulation of hypoxia response element (HRE) was constructed and transduced into NSCs to yield AAV2-5HRE-bFGF-NSCs. Our results showed that its treatment yielded temporally increased expression of bFGF in SCI, and improved scores of functional recovery after SCI compared to vehicle control (AAV2-5HRE-NSCs) based on the analyses of the inclined plane test, Basso–Beattie–Bresnahan (BBB) scale and footprint analysis. Mechanistic studies showed that AAV2-5HRE-bFGF-NSCs treatment increased the expression of neuron-specific neuronal nuclei protein (NeuN), neuromodulin GAP43, and neurofilament protein NF200 while decreased the expression of glial fibrillary acidic protein (GFAP) as compared to the control group. Further, the expressions of autophagy-associated proteins LC3-II and Beclin 1 were decreased, whereas the expression of P62 protein was increased in AAV2-5HRE-bFGF-NSCs treatment group. Taken together, our data indicate that AAV2-5HRE-bFGF-NSCs treatment improved the recovery of SCI rats, which is accompanied by evidence of nerve regeneration, and inhibition of SCI-induced glial scar formation and cell autophagy. Thus, this study represents a step forward towards the potential use of AAV2-5HRE-bFGF-NSCs for future clinical trials of SCI repair.

Abstract Study design 1-year prospective RCT. Objective Examine the effect of implantable pulse generator and low-frequency stimulation of the pelvic nerves using laparoscopic implantation of neuroprosthesis (LION) compared with neuromuscular electrical stimulation (NMES) in SCI. Methods Inclusion criteria: traumatic spinal cord injury (SCI), age 18–55 years, neurological level-of-injury Th4–L1, time-since-injury >1 year, and AIS-grades A–B. Participants were randomized to (A) LION procedure or (B) control group receiving NMES. Primary outcome measure: Walking Index for Spinal Cord Injury (WISCI-II), which is a SCI specific outcome measure assessing ability to ambulate. Secondary outcome measures: Spinal Cord Independence Measure III (SCIM III), Patient Global Impression of Change (PGIC), Penn Spasm Frequency Scale (PSFS), severity of spasticity measured by Numeric Rating Scale (NRS-11); International Spinal Cord Injury data sets-Quality of Life Basic Data Set (QoLBDS), and Brief Pain Inventory (BPI). Results Seventeen SCI individuals, AIS grade A, neurological level ranging from Th4–L1, were randomized to the study. One individual was excluded prior to intervention. Eight participants (7 males) with a mean age (SD) of 35.5 (12.4) years were allocated to the LION procedure, 8 participants (7 males) with age of 38.8 (15.1) years were allocated to NMES. Significantly, 5 LION group participants gained 1 point on the WISCI II scale, (p < 0.013; Fisher´s exact test). WISCI II scale score did not change in controls. No significant changes were observed in the secondary outcome measures. Conclusion The LION procedure is a promising new treatment for individuals with SCI with significant one-year improvement in walking ability.

Object Granulocyte colony-stimulating factor (G-CSF) has neuroprotective effects on the CNS. The authors have previously demonstrated that G-CSF also exerts neuroprotective effects in experimental spinal cord injury (SCI) by enhancing migration of bone marrow–derived cells into the damaged spinal cord, increasing glial differentiation of bone marrow–derived cells, enhancing antiapoptotic effects on both neurons and oligodendrocytes, and by reducing demyelination and expression of inflammatory cytokines. Because the degree of angiogenesis in the subacute phase after SCI correlates with regenerative responses, it is possible that G-CSF's neuroprotective effects after SCI are due to enhancement of angiogenesis. The aim of this study was to assess the effects of G-CSF on the vascular system after SCI. Methods A contusive SCI rat model was used and the animals were randomly allocated to either a G-CSF–treated group or a control group. Integrity of the blood–spinal cord barrier was evaluated by measuring the degree of edema in the cord and the volume of extravasation. For histological evaluation, cryosections were immunostained with anti–von Willebrand factor and the number of vessels was counted to assess revascularization. Real-time reverse transcriptase polymerase chain reaction was performed to assess expression of angiogenic cytokines, and recovery of motor function was assessed with function tests. Results In the G-CSF–treated rats, the total number of vessels with a diameter > 20 μm was significantly larger and expression of angiogenic cytokines was significantly higher than those in the control group. The G-CSF–treated group showed significantly greater recovery of hindlimb function than the control group. Conclusions These results suggest that G-CSF exerts neuroprotective effects via promotion of angiogenesis after SCI.

Background: Patients with spinal cord injuries suffer from some psychological problems, such as inadequate emotional regulation and flexibility for adapting to the post-injury condition. In this regard, acceptance and commitment therapy (ACT) can improve psychological flexibility and emotional regulation. Objectives: The main goal of this study was to analyze the effectiveness of ACT in improving psychological flexibility and emotional regulation in patients with spinal cord injuries. Methods: This quasi-experimental design study was based on a pretest-posttest method with a control group. The study population consisted of all patients with spinal cord injury referred to Jalaeipour Rehabilitation Center in Tehran. The study sample included 30 patients with spinal cord injury selected by the purposive sampling method. The inclusion criteria were patients aged 20 to 55 years, residing in Tehran, and with at least a high school diploma. The injury duration varied between one and five years, and the injuries were thoracic and lumbar injuries and an intermediate score of psychological flexibility and emotion regulation. The exclusion criteria were patients with cervical spinal cord injuries, as well as patients who were simultaneously receiving another psychological treatment together with the subjects who suffered from brain damage. Patients were randomly assigned to the experimental and control groups based on random numbers. There were 15 patients in each group. The intervention group received ACT during eight sessions (1.5-hour group therapy) held once a week at Jalaeipour Rehabilitation Center in Tehran (2018), while the control group received routine care. Dennis and Vander Wal’s cognitive flexibility inventory (CFI) and Gross and John’s emotion regulation questionnaire (ERQ) were completed before and one week after the intervention. The data were analyzed using multivariate analysis of covariance (MANCOVA). Results: There was a significant difference in demographic indicators between the two groups. Based on MANCOVA with the baseline score, the mean scores of psychological flexibility and emotion regulation had a significant difference regarding the results of ACT between the experimental and control groups (P < 0.05). Conclusions: According to the findings, ACT can improve psychological flexibility and emotional regulation in patients with spinal cord injuries.

Transplantation Site

Transplantation of neural stem/progenitor cells (NS/PCs) promotes functional recovery after spinal cord injury (SCI); however, few studies have examined the optimal site of NS/PC transplantation in the spinal cord. The purpose of this study was to determine the optimal transplantation site of NS/PCs for the treatment of SCI. Wild-type mice were generated with contusive SCI at the T10 level, and NS/PCs were derived from fetal transgenic mice. These NS/PCs ubiquitously expressed ffLuc-cp156 protein (Venus and luciferase fusion protein) and so could be detected by in vivo bioluminescence imaging 9 days postinjury. NS/PCs (low: 250,000 cells per mouse; high: 1 million cells per mouse) were grafted into the spinal cord at the lesion epicenter (E) or at rostral and caudal (RC) sites. Phosphate-buffered saline was injected into E as a control. Motor functional recovery was better in each of the transplantation groups (E-Low, E-High, RC-Low, and RC-High) than in the control group. The photon counts of the grafted NS/PCs were similar in each of the four transplantation groups, suggesting that the survival of NS/PCs was fairly uniform when more than a certain threshold number of cells were transplanted. Quantitative RT-PCR analyses demonstrated that brain-derived neurotropic factor expression was higher in the RC segment than in the E segment, and this may underlie why NS/PCs more readily differentiated into neurons than into astrocytes in the RC group. The location of the transplantation site did not affect the area of spared fibers, angiogenesis, or the expression of any other mediators. These findings indicated that the microenvironments of the E and RC sites are able to support NS/PCs transplanted during the subacute phase of SCI similarly. Optimally, a certain threshold number of NS/PCs should be grafted into the E segment to avoid damaging sites adjacent to the lesion during the injection procedure.

Objective: To examine the clinical efficacy of combining Riluzole with mannitol and hyperbaric oxygen therapy in treating thoracolumbar vertebral fracture-induced acute spinal cord injury (ASCI). Methods: From June 2015 to May 2018, 80 patients with thoracolumbar fractures and ASCI who were treated at Baoding First Central Hospital were selected. All patients underwent posterior laminectomy and screw fixation, and they were randomly divided into two groups using a random number table method. The control group received conventional postoperative treatment, while the experimental group was treated with riluzole combined with mannitol and hyperbaric oxygen on the basis of conventional treatment. The recovery of nerve function which included motor function and sensory function, and the changes of serum IL-6, CRP, BDNF, BFGF and other factors before treatment and four weeks after treatment of the two groups of patients were observed and evaluated. Results: After treatment, the motor function scores and sensory function scores of the two groups of patients were improved compared with those before treatment (p<0.05). Compared with the control group, the experimental group improved significantly, and the difference was statistically significant (p<0.05). The levels of IL-6, BDNF and NFGF in the experimental group were significantly lower than those in the control group (p<0.05). Conclusions: For patients with thoracolumbar fractures and ASCI undergoing laminar decompression and fixation, the comprehensive treatment plan of riluzole combined with mannitol and hyperbaric oxygen has certain advantages. Compared with the conventional therapy, it may significantly improve the movement and sensory functions of patients, relieve the inflammatory response of spinal cord, and promote recovery from the injury. doi: https://doi.org/10.12669/pjms.37.2.3418 How to cite this:Li H, Cui J, Fan J, Tong J.
