North American Clinical Trials Network for Spinal Cord Injury Registry: Methodology and Analysis.

The North American Clinical Trials Network (NACTN) for Spinal Cord Injury (SCI) is a consortium of neurosurgery departments at university affiliated hospitals with medical, nursing, and rehabilitation personnel who are skilled in the assessment, evaluation, and management of SCI. NACTN was established with the goal of consistently advancing the quality of life of people with SCI through clinical trials of new therapies that provide robust evidence of safety and effectiveness. A prospective multi-center Registry was created to collect the natural course of the acute traumatic SCI patient from time of injury to 12 months follow-up.

Importance of Prospective Registries and Clinical Research Networks in the Evolution of Spinal Cord Injury Care.

Only 100 years ago, traumatic spinal cord injury (SCI) was commonly lethal. Today, most people who sustain SCI survive with continual efforts to improve their quality of life and neurological outcomes. SCI epidemiology is changing as preventative interventions reduce injuries in younger individuals, and there is an increased incidence of incomplete injuries in aging populations.

History and Accomplishments of the North American Clinical Trials Network for Spinal Cord Injury, 2004-2022.

This is a historical account of the origin and accomplishments of the North American Clinical Trials Network (NACTN) for traumatic spinal cord injury (SCI), which was established in 2004 by Christopher Reeve and Robert Grossman. Christopher Reeve was an actor who became quadriplegic and started the Christopher & Dana Reeve Foundation (CDRF), and Robert Grossman was a neurosurgeon experienced in neurotrauma and a university professor in Houston. NACTN has member investigators at university and military centers in North America and has contributed greatly to the improvement of care, primarily acute care, of patients sustaining traumatic SCI.

Concentrations of Essential Trace Metals in the Brain of Animal Species-A Comparative Study.

The essential trace metals iron, zinc, and copper have a significant physiological role in healthy brain development and function. Especially zinc is important for neurogenesis, synaptogenesis, synaptic transmission and plasticity, and neurite outgrowth. Given the key role of trace metals in many cellular processes, it is important to maintain adequate levels in the brain.
