Caring for patients with a traumatic spinal cord injury

Acute Management of Cervical Spinal Cord Injuries

Traumatic cervical spinal cord injury can cause significant neurologic disability. A cervical spine injury impacts not only the neurologic system but also numerous other organ systems of the body. This complex injury requires a systematic approach to assessment and care aimed at preventing, recognizing, and treating potentially devastating secondary spinal cord injury and multisystem complications. This article focuses on the pathophysiology, initial presentation, and treatment of cervical spinal cord injury by body system.

Preventative Services Use and Risk Reduction for Potentially Preventative Hospitalizations among People with Traumatic Spinal Cord Injury

OBJECTIVE

To examine the risk of potentially preventable hospitalizations (PPHs) for adults (18 years or older) with traumatic spinal cord injury (TSCI) to identify the most common types of preventable hospitalizations and their associative risk factors.

DESIGN

Cohort study.

SETTING

Using 2007-2017 U.S. claims data from the Optum Clinformatics Data Mart, we identified adults (18 years or older) with diagnosis of TSCI (n=5380). Adults without TSCI diagnosis were included as controls (n=1,074,729). Using age and sex, we matched individuals with and without TSCI (n=5173) with propensity scores to address potential selection bias. Generalized linear regression was applied to examine the risk of TSCI on PPHs. Models were adjusted for age; sex; race and ethnicity; Elixhauser comorbidity count; any cardiometabolic, psychological, and musculoskeletal chronic conditions; U.S. Census Division; socioeconomic variables; and use of certain preventative care services. Adjusted odds ratios were compared within a 4-year follow-up period.

PARTICIPANTS

Adults with and without TSCI (N=5,173).

INTERVENTION

Not applicable.

MAIN OUTCOMES MEASURES

Any PPH and specific PPHs RESULTS: Adults with TSCI had higher risk for any PPH (odds ratio [OR], 1.67; 95% CI,1.20-2.32), as well as PPHs because of urinary tract infection (UTI) (OR, 3.78; 95% CI, 2.47-5.79), hypertension (OR, 3.77; 95% CI, 1.54-9.21), diabetes long-term complications (OR, 2.54; 95% CI, 1.34-4.80), and pneumonia (OR, 1.71; 95% CI. 1.21-2.41). Annual wellness visit was associated with reduced PPH risk compared with cases and controls without annual wellness visit (OR, 0.57; 95% CI, 0.46-0.71) and among people with TSCI (OR, 0.69; 95% CI, 0.55-0.86) compared with cases without annual wellness visit.

CONCLUSIONS

Adults with TSCI are at a heightened risk for PPH. They are also more susceptible to certain PPHs such as UTIs, pneumonia, and heart failure. Encouraging the use of preventative or health-promoting services, especially for respiratory and urinary outcomes, may reduce PPHs among adults with TSCI.

Effect of ganglioside combined with Chip Jiaji electro-acupuncture on Nogo-NgR signal pathway in SCI rats

At present, the effect of ganglioside combined with Jiaji electroacupuncture (Jiaji EA) on SCI still remains unclear. This study explores the effect of ganglioside combined with electroacupuncture on Nogo/NgR signal pathway in spinal cord tissue of spinal cord injury (SCI) rats. Basso Beattie Bresnahan (BBB) score was used to evaluate spinal cord function after modeling and 14 days post ganglioside and electroacupuncture treatment. RT-qPCR and western blot were performed to evaluate the expression levels of targets in spinal cord tissue. After 14 days of treatment, the BBB scores of Jiaji EA group, ganglioside group and combination group were all improved. The expression levels of IL-1β, IL-6 and TNF-α in Jiaji EA group, ganglioside group and combination group were significantly lower than those in model group. Both of mRNA and protein expression levels of Nogo-A, NgR and LINGO-1 in the model group were significantly higher than those in the Jiaji EA group, ganglioside group and combination group. Ganglioside combined with Jiaji EA has a stronger effect on promoting the recovery of nerve function. Its mechanism of action may be related to its inhibition of the expression of proinflammatory cytokines such as IL-1β, IL-6 and TNF-α and Nogo-NgR signal pathway to promote neuronal growth. Our results will provide fundamental information for further SCI studies.
