The Evolving Profile of Acute Spinal Cord Injury Demographics, Outcomes and Surgical Treatment in North America: Analysis of a Prospective Multicenter Dataset of 989 Patients.
Changes in demography and injury patterns have altered the profile and outcome of acute spinal cord injury (SCI) over time. This study sought to describe recent trends in epidemiology and early clinical outcomes using the multi-center North American Clinical Trial Network (NACTN) for Spinal Cord Injury Registry. All participants with blunt acute traumatic SCI (n = 782) were grouped into three five-year time intervals from 2005 to 2019 (2005-2009, 2010-2014, and 2015-2019). ⋯ There was a statistically significant increase in cardiac complications (p < 0.0001) and decrease in pulmonary complications (p < 0.0001) during the study period. Data from the NACTN registry shows that the age of participants with acute SCI is increasing, falls have become the major mechanism of injury, and central cord injury is becoming increasingly prevalent. While early surgical intervention for acute SCI is more common in recent years, cardiac complications are more prevalent while pulmonary complications are less prevalent.

Associations between diurnal timing of spinal cord injury and its etiology and co-morbidities.
Circadian rhythms play a role in time-of-day differences in risk, presenting severity and outcomes of stroke. Injury time-of-day effects, however, on occurrence, presenting severity and acute hospital outcomes have not been yet reported in patients with neurotrauma. Therefore, acute post-spinal cord injury hospitalization records of 759 patients from the prospective NACTN registry that contained information about the time of injury were analyzed. ⋯ These data suggest diurnal modulation of spinal cord injury risk because of specific mechanisms such as falls or sports-related accidents. Moreover, some co-morbidities may interact with those injury mechanisms as exemplified by the established risk elevation of falls in those with diabetes mellitus. Finally, while diurnal timing of the injury may modulate presenting severity, more patient records are needed to verify those effects.

Trends in the Use of Corticosteroids in the Management of Acute Spinal Cord Injury in North American Clinical Trials Networks (NACTN) Sites.
Immunomodulatory therapeutics represent a potential neuroprotective strategy for the management of acute spinal cord injury (SCI). One of the most intensely debated neuroprotective drugs has been methylprednisolone sodium succinate (MPSS), which was investigated initially for its role in mitigating lipid peroxidation. More recently, the anti-inflammatory/immunomodulatory properties of MPSS have been increasingly appreciated. ⋯ The 2013 AANS/CNS guidelines and preceding literature appeared to have an impact on dramatically lowering the rates of corticosteroid use for acute SCI in NACTN sites after 2009. Of note, this analysis may not reflect the impact of the 2017 AO Spine Clinical Practice guidelines, which suggested the use of methylprednisolone as a valid practice option for acute SCI, especially for cervical injuries. Enhanced patient involvement in the clinical decision-making process and opportunities to personalize SCI management exist in reference to the use of MPSS in acute SCI.

Randomized Controlled TrialThe RISCIS-PK substudy: An analysis of pharmacokinetics, pharmacodynamics, and impact on axonal degradation of riluzole in patients with traumatic cervical spinal cord injury enrolled in the RISCIS Phase III Randomized Controlled Trial.
To date, no drug therapy has shown significant efficacy in improving functional outcomes in patients with acute spinal cord injury (SCI). Riluzole is an approved benzothiazole sodium channel blocker to attenuate neurodegeneration in amyotrophic lateral sclerosis (ALS) and is of interest for neuroprotection in SCI. In a Phase I clinical trial (ClinicalTrials.gov Identifier: NCT00876889), riluzole was well tolerated with a 2-week treatment at the dose level approved for ALS and exhibited potential efficacy in patients with SCI. ⋯ The development of effective treatment for SCI is challenging. However, the future model-informed and PK-guided drug development and regimen modification can be rationally executed with the optimal dosing regimen design based on the developed 3D PK/PD model. The PK/PD/CO model can serve as a rational guide for future drug development, PKPD model refinement, and extension to other studies in SCI settings.

Interhospital Transfer delays care for spinal cord injury patients: A Report from the North American Clinical Trials Network for Spinal Cord Injury.
Abstract The North America Clinical Trials Network (NACTN) for Spinal Cord Injury (SCI) is a consortium of tertiary medical centers that has maintained a prospective SCI registry since 2004, and it has espoused that early surgical intervention is associated with improved outcome. It has previously been shown that initial presentation to a lower acuity center and necessity of transfer to a higher acuity center reduce rates of early surgery. The NACTN database was evaluated to examine the association between interhospital transfer (IHT), early surgery, and outcome, taking into account distance traveled and site of origin for the patient. ⋯ Patients who underwent IHT to an NACTN site were less likely to have surgery within 24 hours of injury, compared with those directly admitted to the Level 1 trauma facility. Although there was no difference in mortality rates, length of stay, or 6-month AIS conversion between groups, patients with IHT were more likely be older with a less severe level of injury (AIS D). This study suggests there are barriers to timely recognition of SCI in the field, appropriate admission to a higher level of care after recognition, and challenges related to the management of individuals with less severe SCI.
