Abstract

Background: Traumatic Spinal Cord Injury (TSCI) is one of the catastrophic events, the rate of which has been growing compared to the past decades. Complications caused by TSCI have a wide spectrum and can range from complete paralysis to numbness of the limbs. Additional to the injury severity and disability of the patient, the recovery rate depends on the treatment strategies. Despite extensive efforts and research in this field, there are still few treatment options for TSCI patients. Controversial results have been reported, however, spinal cord decompression is the only certainty for the treatment of these patients. In the present study, patients with thoracic and lumbar fractures were undergone decompression, less and more than 24 hours, and the recovery rate (RR) was compared after 6 months.
Methods: In this study, patients with lumbar and thoracic fractures who were referred to the neurosurgery department of Ahvaz Golestan Hospital during May 2019 to December 2021 were included. Decompression was performed at the fracture level as a total and at the upper and lower levels of the fracture as a partial decompression. To evaluate fine motor movements, picking up a small object with toes and following a rectangular path were used. Also, the gross motor movements, upper and lower proximal and distal muscle forces were measured.
Results: 160 patients including 133 men (83.1%) and 16.9% women (27) with 36±12 years mean age were included. The most fracture location was lumbar (53.1%), followed by the thoracic (43.1%) and fractures in both regions (3.8%). The most injured  vertebras were L1 (27.5%) and T12 (18.8%). Six months later, 61.9% of patients had a good score for removing a small object with toe, of which 67.5% belonged to patients with<24 hours surgery (P=0.01). Also, RR for ability to follow a rectangle (P=0.017) and lower limit gross motor were significantly better in patients with<24 surgery (P=0.02). However, no significant difference was found between the two groups for improved sensations (P<0.05).
Conclusion: This study showed that decompression<24 hours in TSCI is associated with a significant improvement in lower fine movements.

Abstract

Background: Spinal cord injury (SCI) is a significant medical and social issue, leading to varying degrees of sensory and motor impairments. Most men experience sexual dysfunction and fertility problems. These issues can be partially attributed to pathophysiological mechanisms, including damage caused by reactive oxygen species (ROS). Targeted antioxidant therapy can significantly reduce oxidative stress and neuro inflammation. This study sought to examine the impact of selenium and astaxanthin on sperm parameters and the recovery of sensory-motor function in rats with spinal cord injury (SCI).
Methods: This experimental study utilized the rat animal model and was carried out at the Neuroscience Research Center Laboratory of Tabriz University of Medical Sciences from December 30, 2022, to November 27, 2023. Fifty adults male Wistar rats were randomly allocated into five groups of ten: control, sham, SCI, selenium-supplemented, and astaxanthin-supplemented. Except for the control and sham groups, spinal cord injury was induced in all other groups. Six weeks after the injury and upon completion of the treatment, the effects of selenium and astaxanthin supplementation on sperm parameters and spinal cord repair were assessed. The Basso, Beattie, and Brenham (BBB) scale was employed to evaluate motor function, while the Von Frey test was utilized to assess sensory status.
Results: A considerable rise in sperm concentration was noted in both the selenium-fed group and the astaxanthin-fed group when compared to the spinal cord injury group (P=0.001). Supplementation with selenium and astaxanthin improved sperm concentration, progressive motility, and viability, bringing these parameters close to control levels (P<0.001). However, neither of these substances had an effect on abnormal sperm morphology (P>0.05). Both selenium and astaxanthin supplementation enhanced the motor and sensory functions of the injured rats (P<0.001), with selenium showing a greater role in promoting repair compared to astaxanthin (P<0.001).
Conclusion: Selenium and astaxanthin supplements improved sperm parameters, except for sperm morphology, and were effective in enhancing motor and sensory functions after spinal cord injury. Selenium was found to be more effective than astaxanthin in promoting spinal cord repair.
