Spinal AND Cord AND Injury

BACKGROUND: Spinal cord injury (SCI)-induced neuroinflammation and oxidative stress (OS) are crucial events causing neurological dysfunction. Aconitate decarboxylase 1 (ACOD1) and its metabolite itaconate (Ita) inhibit inflammation and OS by promoting alkylation of Keap1 to induce Nrf2 expression; however, it is unclear whether there is another pathway regulating their effects in inflammation-activated microglia after SCI. METHODS: Adult male C57BL/6 ACOD1-/-  mice and their wild-type (WT) littermates were subjected to a moderate thoracic spinal cord contusion...

OBJECTIVES: There is still controversy over the choice of treatment for end-stage spinal metastases. With the continuous development of microwave technology in spinal tumors, related studies have reported that microwave combined with techniques such as pedicle screw fixation and percutaneous vertebroplasty can achieve the purpose of tumor ablation, relieving spinal cord compression, enhancing spinal stability, effectively relieving pain, and reducing recurrence rates. This study aimed to analyze the effectiveness of microwave ablation combined with decompression and pedicle screw fixation in the palliative management of spinal metastases with pathological fractures...

The pathogenesis of neuropathic pain (NP) is complex, and there are various pathological processes. Previous studies have suggested that lncRNA PCAT19 is abnormally expressed in NP conduction and affects the occurrence and development of pain. The aim of this study is to analyze the role and mechanism of PCAT19 in NP induced by chronic compressive nerve injury (CCI) in mice. In this study, C57BL/6 mice were applied to establish the CCI model. sh-PCAT19 was intrathecally injected once a day for 5 consecutive days from the second day after surgery...

Improvements in care and rehabilitation have resulted in a higher proportion of people living with spinal cord injury (SCI), which calls for an increased focus on participation and autonomy. This observational cross-sectional study investigated the impact of SCI on autonomy and how it correlates to activity performance and upper extremity functioning. A total of 25 adults (mean age 58 years) with chronic cervical or thoracic SCI were included. Self-perceived autonomy was measured with Impact on Participation and Autonomy questionnaire, independence in activities of daily living (ADL) with Spinal Cord Independence Measure, upper extremity functioning with Action Research Arm Test (ARAT) and kinematic measures of the drinking task...

STUDY DESIGN: Qualitative exploratory study. OBJECTIVES: To understand the lived experiences of individuals with spinal cord injuries or disorders (SCI/D) who use wheelchairs during air travel in the United States (US), with a focus on the challenges and barriers to accessing this form of transportation. SETTING: Wheelchair users with SCI/D living in the community in the US. METHODS: Semi-structured interviews were used to collect data from six wheelchair users with SCI/D...

Inflammation is one of the key injury factors for spinal cord injury (SCI). Exosomes (Exos) derived from M2 macrophages have been shown to inhibit inflammation and be beneficial in SCI animal models. However, lacking targetability restricts their application prospects. Considering that chemokine receptors increase dramatically after SCI, viral macrophage inflammatory protein II (vMIP-II) is a broad-spectrum chemokine receptor binding peptide, and lysosomal associated membrane protein 2b (Lamp2b) is the key membrane component of Exos, we speculated that vMIP-II-Lamp2b gene-modified M2 macrophage-derived Exos (vMIP-II-Lamp2b-M2-Exo) not only have anti-inflammatory properties, but also can target the injured area by vMIP-II...

One cannot survive without regularly urinating and defecating. People with neurological injury (spinal cord injury, traumatic brain injury, stroke) or disease (multiple sclerosis, Parkinson's disease, spina bifida) and many elderly are unable to voluntarily initiate voiding. The great majority of them require bladder catheters to void urine and "manual bowel programs" with digital rectal stimulation and manual extraction to void stool. Catheter-associated urinary tract infections frequently require hospitalization, while manual bowel programs are time-consuming (1-2 hours), stigmatizing, and cause rectal pain and discomfort...

BACKGROUND: BMSC-secreted exosomes (BMSC-Exos) have shown potential for promoting behavioral recovery following spinal cord injury (SCI). However, its role in blocking astrocyte activation remains unclear. Thus, this study aimed to determine whether BMSC-Exos impair the function of astrocytes following SCI in mice and to seek the mechanism. METHODS: BMSC-Exos were collected by ultracentrifugation and identified. The SCI mice were developed by laminectomy combined with spinal cord shock, followed by BMSC-Exos or nerve growth factor (positive control) treatment...

BACKGROUND: Lycium barbarum glycopeptide (LbGp), extracted from the traditional Chinese medicine (TCM) of Lycium barbarum (LB), provides a neuroprotective effect against neurodegenerative and neuroimmune disorders contributing to its immunomodulatory and anti-inflammatory roles. Neuromyelitis optica spectrum disorders (NMOSD) is an autoimmune-mediated central nervous system (CNS) demyelinating disease, clinically manifested as transverse myelitis (TM) and optic neuritis. However, no drug has been demonstrated to be effective in relieving limb weakness and visual impairment of NMOSD patients...

Semi-recumbent cycling performed from a wheelchair is a popular rehabilitation exercise following spinal cord injury (SCI) and is often paired with functional electrical stimulation. However, biomechanical assessment of this cycling modality is lacking, even in unimpaired populations, hindering the development of personalised and safe rehabilitation programs for those with SCI. This study developed a computational pipeline to determine lower limb kinematics, kinetics, and joint contact forces (JCF) in 11 unimpaired participants during voluntary semi-recumbent cycling using a rehabilitation ergometer...

Existing methods for studying neural circuits and treating neurological disorders are typically based on physical and chemical cues to manipulate and record neural activities. These approaches often involve predefined, rigid, and unchangeable signal patterns, which cannot be adjusted in real time according to the patient's condition or neural activities. With the continuous development of neural interfaces, conducting in vivo research on adaptive and modifiable treatments for neurological diseases and neural circuits is now possible...

BACKGROUND: There has been growing interest in using the traditional Chinese herb Buyang Huanwu Decoction (BHD) as a potential treatment for spinal cord injury (SCI), owing to its long-used treatment for SCI in China. However, the efficacy and safety of BHD treatment for SCI remain widely skeptical. This meta-analysis aims to assess the safety and efficacy of BHD in managing SCI. METHOD: A comprehensive literature search was conducted across several databases, including PubMed, EMBASE, Cochrane Library, CNKI, Wanfang, VIP, and Sinomed, up to January 1, 2024...

METHODS: Patients were randomly assigned to two groups (iTBS + RT Group, n = 18, and RT Group, n = 18)...

BACKGROUND: Most studies focus on the risk factors associated with the development of pressure ulcers (PUs) during acute phase or community care for individuals with spinal cord injury (SCI). OBJECTIVES: This study aimed to i) compare clinical and demographic characteristics of inpatients after SCI with PUs acquired during rehabilitation vs inpatients without PUs and ii) evaluate an existing PU risk assessment tool iii) identify first PU predictors. METHODS: Individuals (n = 1,135) admitted between 2008 and 2022 to a rehabilitation institution within 60 days after SCI were included...

Accumulating evidence has demonstrated that M1 microglial polarization and neuroinflammation worsen the development of neuropathic pain. However, the mechanisms underlying microglial activation during neuropathic pain remain incompletely understood. Myeloid-epithelial-reproductive tyrosine kinase (Mer), which is a member of the Tyro-Axl-Mer (TAM) family of receptor tyrosine kinases, plays a crucial role in the regulation of microglial polarization. However, the effect of Mer on microglial polarization during neuropathic pain has not been determined...
