ReviewThe bulbocavernosus reflex (BCR) has no prognostic features during the acute evaluation of spinal cord injuries.
The bulbocavernosus reflex (BCR) has been used during the initial evaluation of a spinal cord injury patient as a metric to determine prognosis and whether the patient is in "spinal shock." This reflex has been less utilized over the last decade, and therefore a review was performed to assess the value of BCR in patient prognosis. The North American Clinical Trials Network (NACTN) for Spinal Cord Injury (SCI) is a consortium of tertiary medical centers that includes a prospective SCI registry. The NACTN registry data was analyzed to evaluate the prognostic implication of the BCR during the initial evaluation of a spinal cord injury patient. ⋯ In addition, cohorts were not different in surgery decision (p = 0.7762) and injury to surgery time (p = 0.0681). In our review of the NACTN spinal cord registry, the BCR did not provide prognostic utility in the acute evaluation of spinal cord injury patients. Therefore, it should not be used as a reliable marker for predicting neurological outcomes post-injury.

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.

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.

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.

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.
