Effects of transcranial magnetic stimulation on axonal regeneration in the corticospinal tract of female rats with spinal cord injury.

BACKGROUND: This study investigates the potential of transcranial magnetic stimulation (TMS) to enhance spinal cord axon regeneration by modulating corticospinal pathways and improving motor nerve function recovery in rats with spinal cord injury (SCI). NEW METHOD: TMS is a non-invasive neuromodulation technique that generates a magnetic field to activate neurons in the brain, leading to depolarization and modulation of cortical activity. Initially utilized for brain physiology research, TMS has evolved into a diagnostic and prognostic tool in clinical settings, with increasing interest in its therapeutic applications. However, its potential for treating motor dysfunction in SCI has been underexplored. RESULTS: The TMS intervention group exhibited significant improvements compared to the control group across behavioral assessments, neurophysiological measurements, pathological analysis, and immunological markers. COMPARISON WITH EXISTING METHODS: Unlike most studies that focus on localized spinal cord injury or muscle treatments, this study leverages the non-invasive, painless, and highly penetrating nature of TMS to focus on the corticospinal tracts, exploring its therapeutic potential for SCI. CONCLUSIONS: TMS enhances motor function recovery in rats with SCI by restoring corticospinal pathway integrity and promoting axonal regeneration. These findings highlight TMS as a promising therapeutic option for SCI patients with currently limited treatment alternatives.

TERLIPRESSIN COMBINED WITH NOREPINEPHRINE IN THE TREATMENT OF SEPTIC SHOCK: A SYSTEMATIC REVIEW.

ABSTRACT: Objective: The objective of this study was to provide an in-depth analysis of the advantages and potential research directions concerning the utilization of terlipressin (TP) in combination with norepinephrine (NE) for the management of septic shock. Methods: A systematic search was conducted across five major electronic databases, namely, PubMed, Cochrane, Embase, ScienceDirect, and MEDLINE, using the Boolean method. The search encompassed articles published until May 22, 2023. Randomized controlled trials investigating the efficacy of TP combined with NE in the treatment of patients with septic shock were considered for inclusion. Results: A total of seven trials met the inclusion criteria. The combination therapy of TP and NE exhibited potential benefits in the treatment of adult patients suffering from septic shock. Furthermore, the concurrent administration of TP with NE demonstrated improvements in cardiac output and central venous pressure. However, it is important to acknowledge the presence of certain risks and potential adverse events, including an elevated risk of peripheral ischemia. Conclusions: The available evidence supports the notion that early combination therapy involving NE and TP holds promise in terms of reducing the required dosage of NE, enhancing renal perfusion, and improving microcirculation in patients diagnosed with septic shock.
