BACKGROUND CONTEXT: Intraoperative neurophysiological monitoring (IONM) is used to reduce the risk of spinal cord injury during pediatric spinal deformity surgery. Significant reduction and/or loss of IONM signals without immediate recovery may lead the surgeon to acutely abort the case. The timing of when monitorable signals return remains largely unknown. PURPOSE: The goal of this study was to investigate the correlation between IONM signal loss, clinical examination, and subsequent normalization of IONM signals after aborted pediatric spinal deformity surgery to help determine when it is safe to return to the operating room...

Acute thoracolumbar myelopathy is a common neurological presentation in dogs. Although certain spinal conditions present with characteristic clinical pictures, managing such cases with clinical reasoning alone (i.e., without cross-sectional imaging) has never been explored. The aim of this study was to define the outcome of patients with suspected intervertebral disc extrusion (IVDE), ischaemic myelopathy (IM) or acute non-compressive nucleus pulposus extrusion (ANNPE) that were managed with clinical reasoning alone...

Activity-based therapy (ABT) is a therapeutic approach with multiple benefits including promoting neurorecovery and reducing the likelihood of secondary complications in people living with spinal cord injury (SCI). Barriers and facilitators to ABT implementation for SCI rehabilitation have been studied from various perspectives through qualitative research. However, these viewpoints have not been synthesized to identify challenges of and strategies for implementing ABT across the Canadian healthcare system...

OBJECTIVE: To emphasize preventive measures and outline management strategies for inadvertent ureteral cannulation. METHODS: We present a case report and conduct a literature review of 39 case reports on ureteral cannulation, examining a total of 48 patients. RESULTS: About 67% of the cases were female, and long-term catheterization was observed in 67% of the cases. Neurological conditions such as spinal cord injury (SCI), stroke, dementia, multiple sclerosis, and myasthenia gravis were the primary factors (48%) in ureteral cannulation...

BACKGROUND: Traumatic spinal cord injury (SCI) is the most common preventable cause of morbidity. Despite rapid advances in medicine, effective pharmacological treatment against SCI has not yet been confirmed. This study aimed to investigate the possible anti-inflammatory, antiapoptotic, and neuroprotective effects of safinamide after SCI in a rat model. METHODS: A total of 40 male Wistar albino rats were randomly divided into four groups. Group 1 underwent only laminectomy...

BACKGROUND: Dynamic changes in neuronal activity and in noradrenergic locus coeruleus (LC) projections have been proposed during the transition from acute to chronic pain. Thus, we explored the cellular cFos activity of the LC and its projections, in conjunction with spontaneous pain-like behavior in neuropathic rats. METHODS: Tyrosine hydroxylase:Cre and wild-type Long-Evans rats, males and females, were subjected to chronic constriction injury (CCI) for 2 (short-term, CCI-ST) or 30 days (long-term, CCI-LT), evaluating cFos and Fluoro-Gold expression in the LC, and its projections to the spinal cord (SC) and rostral anterior cingulate cortex (rACC)...

OBJECTIVE: The objective of this scoping review is to identify the timings and types of early rehabilitation after spinal cord injuries (SCI) that are documented in the literature, as well as identify possible research gaps in this field. INTRODUCTION: Preclinical and clinical studies support the idea that early rehabilitation may be beneficial for patients with acute SCI. However, the timing and types of rehabilitation that should and could be used in the acute stage are still unclear...

INTRODUCTION: In the acute phase after a spinal cord injury or disease (SCI/D), various therapeutic assessments and interventions are applied with the goal of restoring structures, preventing complications and preparing the patient as best as possible for further activity and finally participation. The goal was to identify and evaluate the available evidence on assessments and interventions for body functions and structures to prepare adults with acute spinal cord SCI/D for activity and participation during the first 14 days...

tRNA-derived small RNAs (tsRNAs) are novel small non-coding RNAs originating from mature or precursor tRNAs (pre-tRNA), typically spanning 14 to 30 nt. The Mitogen-activated protein kinases (MAPK) pathway orchestrates cellular responses, influencing proliferation, differentiation, apoptosis, and transformation. tsRNAs influence the expression of the MAPK signaling pathway by targeting specific proteins within the pathway. Presently, four MAPK-linked tsRNAs have implications in gastric cancer (GC) and high-grade serous ovarian cancer (HGSOC)...

Most human spinal cord injuries are anatomically incomplete, leaving some fibers still connecting the brain with the sublesional spinal cord. Spared descending fibers of the brainstem motor control system can be activated by deep brain stimulation (DBS) of the cuneiform nucleus (CnF), a subnucleus of the mesencephalic locomotor region (MLR). The MLR is an evolutionarily highly conserved structure which initiates and controls locomotion in all vertebrates. Acute electrical stimulation experiments in female adult rats with incomplete spinal cord injury conducted in our lab showed that CnF-DBS was able to re-establish a high degree of locomotion five weeks after injury, even in animals with initially very severe functional deficits and white matter lesions up to 80-95%...

Background The aim of this study is to emphasize the need to be careful in terms of internal organ injuries in patients with isolated transverse process fracture (ITPF), and to investigate the effectiveness of corset use in controlling acute pain. Methods This is a retrospective study including 72 patients with only transverse process fractures secondary to trauma, who were admitted to the Emergency Department of Sakarya University Research and Training Hospital between January 2020 and October 2022. The radiological diagnoses were collected from spinal vertebral computed tomography images...

Neurofilament-light chain (NF-L) and phosphorylated neurofilament-heavy chain (pNF-H) are axonal proteins that have been reported as potential diagnostic and prognostic biomarkers in traumatic brain injury (TBI). However, detailed temporal profiles for these proteins in blood, and interrelationships in the acute and chronic time periods post-TBI have not been established. Our objectives were 1) to characterize acute-to-chronic serum NF-L and pNF-H profiles after moderate-severe TBI, as well as acute cerebrospinal fluid (CSF) levels, 2) to evaluate CSF and serum NF-L and pNF-H associations with each other, and 3) to assess biomarker associations with global patient outcome using both the Glasgow Outcome Scale-Extended (GOS-E) and Disability Rating Scale (DRS)...

INTRODUCTION: We aimed to compare holmium laser enucleation of the prostate (HoLEP) outcomes in patients with and without neurologic diseases (ND). METHODS: A prospectively maintained database of patients undergoing HoLEP from January 2021 to April 2022 was reviewed. The following NDs were included: diabetes-related neuropathy/neurogenic bladder, Parkinson's disease, dementia, cerebrovascular accident, multiple sclerosis, traumatic brain injury, transient ischemic attack, brain/spinal tumors, myasthenia gravis, spinal cord injury, and other...

After spinal cord injury (SCI), re-establishing cellular homeostasis is critical to optimize functional recovery. Central to that response is PERK signaling, which ultimately initiates a pro-apoptotic response if cellular homeostasis cannot be restored. Oligodendrocyte (OL) loss and white matter damage drive functional consequences and determine recovery potential after thoracic contusive SCI. We examined acute (<48 h post-SCI) and chronic (6 weeks post-SCI) effects of conditionally deleting Perk from OLs prior to SCI...

The α2-adrenoceptor agonist dexmedetomidine is a commonly used drug for sedatives in clinics and has analgesic effects; however, its mechanism of analgesia in the spine remains unclear. In this study, we systematically used behavioural and transcriptomic sequencing, pharmacological intervention, electrophysiological recording and ultrasound imaging to explore the analgesic effects of the α2-adrenoceptor and its molecular mechanism. Firstly, we found that spinal nerve injury changed the spinal transcriptome expression, and the differential genes were mainly related to calcium signalling and tissue metabolic pathways...

Translation fracture of the lumbar spine is a rare but serious condition that necessitates prompt medical attention. This injury can cause nerve damage, spinal cord compression, and other complications that can affect motor function. The motoric outcomes of this fracture type depend on a variety of factors, including the severity and location of the fracture, the age and general health of the patient, and the timeliness and effectiveness of treatment. Accurate diagnosis and treatment of these injuries is important to prevent further neurological damage and improve motoric outcomes...

INTRODUCTION: NeuroAiD (MLC601 & MLC901)'s neuroprotective capabilities include limiting exaggerated calcium influx, decreasing excitotoxicity, reducing oxidative stress, and preventing glutamate-induced cell death. It has also been shown to facilitate synaptogenesis, neurogenesis, and neuroplasticity. However, its clinical efficacy has primarily been studied in the context of brain injuries, particularly stroke. NeuroAiD's potential application in SCI remains largely untapped. CASE PRESENTATION: A 34-year-old male presented with C4 complete tetraplegia...

BACKGROUND: This study aimed to determine risk factors for poor in-hospital outcomes in a large cohort of older adult patients with acute non-traffic traumatic spinal cord injury (tSCI). METHODS: This is a population-based, retrospective, observational study. Data of older adults ≥65 years with a primary discharge diagnosis of acute non-traffic tSCI were extracted from the US National Inpatient Sample (NIS) database 2005-2018. Traffic-related tSCI admissions or patients lacking complete data on age, sex and outcomes of interest were excluded...

High levels of reactive oxygen species (ROS) are known to play a critical role in the secondary cascade of spinal cord injury (SCI). The scavenging of ROS has emerged as a promising approach for alleviating acute SCI. Moreover, identifying the precise location of the SCI site remains challenging. Enhancing the visualization of the spinal cord and improving the ability to distinguish the lesion site are crucial for accurate and safe treatment. Therefore, there is an urgent clinical need to develop a biomaterial that integrates diagnosis and treatment for SCI...
