Omega-3 Fatty Acid Supplementation and Warfarin: A Lethal Combination in Traumatic Brain Injury.

Polyunsaturated fatty acids such as omega-3 eicosapentaenoic acid and omega-6 docosahexaenoic acid, found in over-the-counter fish oil supplements, are often consumed for their beneficial, prophylactic, anti-inflammatory effects. Although the mechanisms of action are not fully known, a diet rich in polyunsaturated fats may reduce the risk of hyperlipidemia, atherosclerosis, high low-density lipoprotein cholesterol levels, hypertension, and inflammatory diseases. Masked by its many benefits, the risks of omega-3 fatty acid supplementation are often underappreciated, particularly its ability to inhibit platelet aggregation and promote bleeding in patients taking anticoagulant medications. The following details the clinical case of an elderly patient taking warfarin and fish oil supplementation whose warfarin-induced coagulopathy could not be reversed after suffering blunt head trauma.

A bitter pill to swallow: dysphagia in cervical spine injury.

BACKGROUND: Dysphagia is a common complication after cervical spine trauma with spinal cord injury. We sought to characterize the prevalence of dysphagia within a total cervical spinal injury (CSI) population, considering the implications of spinal cord injury status and age on dysphagia development. We hypothesized that while greater rates of dysphagia would be found in geriatric and spinal cord-injured subgroups, all patients presenting with CSI would be at heightened risk for swallowing dysfunction. METHODS: All trauma admissions to a level II trauma center from January 2010 to April 2014 with CSI were retrospectively reviewed. CSI was classified as any ligamentous or cervical spinous fracture with or without cord injury. Patients failing a formal swallow evaluation were considered dysphagic. The implications of dysphagia development on age and spinal cord injury status were assessed in univariate and multivariate analyses. RESULTS: A total of 481 patients met study inclusion criteria, of which 123 (26%) developed dysphagia. Within the dysphagic subpopulation, 90 patients (73%) were geriatric, and 23 (19%) sustained spinal cord injury. The dysphagic subpopulation was predominantly free from spinal cord injury (81%). Multivariate analyses found age (adjusted odds ratio: 1.06; 95% confidence interval 1.04-1.07; P < 0.001) and spinal cord injury (adjusted odds ratio: 2.69; 95% confidence interval 1.30-5.56; P = 0.008) to be significant predictors of dysphagia development. CONCLUSIONS: Despite spinal cord-injured patients being at increased risk for dysphagia, most of the dysphagic subpopulation was free from spinal cord injury. Geriatric and CSI patients with or without cord injury should be at heightened suspicion for dysphagia development.

An analysis of neurosurgical practice patterns and outcomes for serious to critical traumatic brain injuries in a mature trauma state.

BACKGROUND: We sought to characterize trends in neurosurgical practice patterns and outcomes for serious to critical traumatic brain injuries from 2003 to 2013 in the mature trauma state of Pennsylvania. METHODS: All 2003 to 2013 admissions to Pennsylvania's 30 accredited Level I to II trauma centers with serious to critical traumatic brain injuries (head Abbreviated Injury Scale [AIS] score ≥ 3, Glasgow Coma Scale [GCS] score < 13) were extracted from the state registry. Adjusted temporal trend tests controlling for demographic and injury severity covariates assessed the impact of admission year on intervention rates (craniotomy, craniectomy, and intracranial pressure monitor/ventriculostomy [ICP]) and outcome measures for the total population as well as serious (head AIS score ≥ 3; GCS score, 9-12) and critical (head AIS score ≥ 3, GCS score ≤ 8) subgroups. RESULTS: A total of 22,229 patients met inclusion criteria. Admission year was significantly associated with an adjusted increase in craniectomy (adjusted odds ratio [AOR], 1.12 [1.09-1.14]; p < 0.001) and ICP rates (AOR, 1.03 [1.02-1.04]; p < 0.001) and a decrease in craniotomy rate (AOR, 0.96 [0.95-0.97]; p < 0.001). No significant trends in adjusted mortality were found for the total study population (AOR, 1.01 [1.00-1.02]; p = 0.150); however, a significant reduction was found for the serious subgroup (AOR, 0.95 [0.92-0.98]; p = 0.002), and a significant increase was found for the critical subgroup (AOR, 1.02 [1.01-1.03]; p = 0.004). CONCLUSION: Total study population trends showed a reduction in rates of craniotomy and increase in craniectomy and ICP rates without any change in outcome. Despite significant adaptations in neurosurgical practice patterns from 2003 to 2013, only patients with serious head injuries are experiencing improved survival. LEVEL OF EVIDENCE: Prognostic and epidemiologic study, level III; therapeutic study, level IV.
