BACKGROUND: Autonomic dysreflexia is a severe and potentially life-threatening condition in patients with spinal cord injury, as it can lead to myocardial ischemia, brain hemorrhage, or even death. Urodynamic investigation is the gold standard to assess neurogenic lower urinary tract dysfunction due to spinal cord injury and reveal crucial pathological findings, such as neurogenic detrusor overactivity. However, neurogenic detrusor overactivity and urodynamic investigation are known to be leading triggers of autonomic dysreflexia...

The nutrient needs of athletes with Spinal Cord Injury (SCI) are dependent on their physiological alterations and training status. Limited research is available regarding dietary intake of elite athletes with SCI and possible nutrient deficiencies. Therefore, the purpose of this study was to examine dietary intake of elite athletes with SCI, and determine dietary intake inadequacies based on the Estimated Average Requirement (EAR) comparisons. Additionally, the average energy and macronutrient (carbohydrate, protein, and fat) intake was compared based on level of injury (C level, T1-T6, T7-T12, Lumbar)...

BACKGROUND: Spinal cord injury (SCI) is a devastating disease, which results in tissue loss and neurologic dysfunction. NLRP3 inflammasome plays an important role in the mechanism of diverse diseases. However, no studies have demonstrated the role of NLRP3 inflammasome and the effects of NLRP3 inflammasome inhibitors in a mouse model of SCI. We investigated whether inhibition of NLRP3 inflammasome activation by the pharmacologic inhibitor BAY 11-7082 or A438079 could exert neuroprotective effects in a mouse model of SCI...

INTRODUCTION: Syringomyelia is a disorder in which a cyst, or syrinx, develops within the spinal cord. Historically, syringomyelia in post-traumatic spinal cord injury has been uncommon; however, its diagnosis has been increasing due to the advances in medical technology. Syringomyelia that involves the entire spinal cord, or holocord, is rare after traumatic spinal cord injury, with only a few cases reported in the literature. CASE PRESENTATION: We present a case of a 57-year-old male who had a motorcycle accident 30 years ago resulting in a spinal cord injury, who presented a rapid decline in the function of his left upper extremity...

Individuals with chronic spinal cord injury (SCI) are at a heightened risk of cardiovascular disease (CVD) resulting from autonomic nervous system dysfunction, physical inactivity, and increased inflammatory processes. Arterial stiffness (AS) is recognized as an independent risk factor for CVD and, specifically, pulse wave analysis (PWA) has proven to be a useful tool to predict and track structural arterial changes that reflect arteriosclerosis. The augmentation index (AI) can be used to estimate AS and is derived from the amplitude and timing of the blood pressure (BP) wave reflection in a peripheral artery...

Spinal cord injury (SCI) causes permanent changes in motor, sensory, and autonomic functions. Unfortunately, there are no stable cures and current treatments include surgical decompression, methylprednisolone, and hemodynamic control that lead to modest function recovery. Fumaric acid esters (FAEs) were firstly used in the management of an immunological skin disorder, such as psoriasis. Because of their potent anti-inflammatory effects, they have been introduced in multiple sclerosis (MS). Investigation has shown not only an anti-inflammatory, but also supposed neuroprotective mechanism of action...

The Wnt canonical or the Wnt/β-catenin pathway has been implicated in the regulation of several physiopathological pathways such as inflammation. Glucocorticoids (GCs) are administered widely to treat inflammation in several diseases, including spinal cord injury (SCI). The aim of this study was to evaluate whether the Wnt canonical pathway is involved in experimental SCI and whether it is implicated in the anti-inflammatory activity of two different GCs: the methylprednisolone sodium succinate (MPSS), considered the standard treatment for acute SCI, and mometasone furoate (MF), mainly administered for the treatment of airway and skin diseases...

INTRODUCTION: Traumatic injury to the spinal cord activates B cells, which culminates in the synthesis of autoantibodies. The functional significance of this immune response is unclear. Antibodies produced after SCI caused pathology, in part by activating intraspinal complement and cells bearing Fc receptors. These data indicate that B cells, through the production of antibodies, affect pathology in SCI. There is increasing appreciation of the important role of B cells in spinal cord trauma and consequently, increasing interest in treating these disorders through B cell-depletion therapy...

Significant vascular changes occur subsequent to spinal cord injury (SCI), which contribute to progressive pathophysiology. In the present study, we used female Wistar rats (300-350 g) and a 35-g clip-compression injury at T6 to T7 to characterize the spatial and temporal vascular changes that ensue post-SCI. Before sacrifice, animals were injected with vascular tracing dyes (2% Evans Blue (EB) or fluorescein isothiocyanate/Lycopersicon esculentum agglutinin [FITC-LEA]) to assess blood-spinal cord barrier (BSCB) integrity or vascular architecture, respectively...
