Demographics, Mechanism of Injury and Outcomes for Acute Upper and Lower Cervical Spinal Cord Injuries - An Analysis of 470 Patients in the Prospective, Multicenter North American Clinical Trials Network (NACTN) Registry.
There is a paucity of data comparing the demographics, mechanism of injury, and outcomes of upper versus lower cervical spinal cord injuries (cSCI). The study objective was to define different clinical manifestations of cSCI. Data were collected prospectively through centers of the North American Clinical Trials Network (NACTN). ⋯ In conclusion, there appears to be a natural demarcation of injury type between C3 and C4. Upper cSCI (C1-C3) was more associated with falls and diabetes, whereas lower cSCI (C4-C7) was more associated with sports, worse ASIA scores, and more complications. Further research will be needed to understand the mechanistic and biological differences between these two groups and whether different treatments may be appropriate for each of these groups.

An Introduction to the North American Clinical Trials Network for Spinal Cord Injury Special Edition: Reflections on Accomplishments and a Look to the Future.
The North American Clinical Trials Network (NACTN) has been established as a network of translational clinical research centers focused on traumatic spinal cord injury (SCI) with the goals of facilitating clinical translational research, promotion of enhanced clinical care protocols including the principle of early surgery for SCI, and improving outcomes for individuals with acute SCI. Since its foundation in 2004 by Dr. Robert Grossman, NACTN has evolved into a powerful multi-stakeholder consortium of eight neurosurgical department faculties at university-affiliated institutions in the United States and Canada, a data management center, and a pharmacological center. ⋯ The Focus Issue also includes a detailed analysis of the pharmacokinetics and pharmacodynamics of riluzole in the setting of acute SCI (RISCIS-PK study). Additional achievements include key contributions to the evidence supporting the role of early surgery in acute SCI, and a better understanding of the impact of complications on the outcomes of SCI. Future directions of NACTN will build on past accomplishments and focus on enhanced collaborations with other SCI networks, advanced analytics to examine large datasets, and a greater focus on chronic SCI.

Traumatic spinal cord injury (SCI) causes a sudden onset multi-system disease, permanently altering homeostasis with multiple complications. Consequences include aberrant neuronal circuits, multiple organ system dysfunctions, and chronic phenotypes such as neuropathic pain and metabolic syndrome. Reductionist approaches are used to classify SCI patients based on residual neurological function. ⋯ To better understand the evolution from acute SCI to chronic SCI multi-system states, we propose a topological phenotype framework integrating bioinformatics, physiological data, and allostatic load tested against accepted established recovery metrics. This form of correlational phenotyping may reveal critical nodal points for intervention to improve recovery trajectories. This study examines the limitations of current classifications of SCI and how these can evolve through systems medicine.

Variability in Early Surgery for Acute Cervical Spinal Cord Injury Patients: An Opportunity for Enhanced Care Delivery.
Data supporting the benefits of early surgical intervention in acute spinal cord injury (SCI) is growing. For early surgery to be accomplished, understanding the causes of variabilities that effect the timing of surgery is needed to achieve this goal. The purpose of this analysis is to determine factors that affect the timing of surgery for acute cervical SCI within the North American Clinical Trials Network (NACTN) for SCI registry. ⋯ In the present study of cervical SCI, NACTN achieved its goal of early surgery in 73.4% of patients from 2005-2019 who arrived within 24 h of their injury. Variability in achieving this goal was related to severity of neurological injury, the day of the week, and the treating NACTN center. Evaluating variations within our network improves understanding of potential systemic limitations and our decision-making process to accomplish the goal of early surgery.
