Abstract
BACKGROUND Spinal cord ischemia (SCI) is a dreaded complication of thoracic and complex endovascular aortic repair (TEVAR/cEVAR). Controversy exists surrounding cerebrospinal fluid drain (CSFD) use, especially preoperative prophylactic placement, owing to concerns regarding catheter-related complications. However, these risks are balanced by the widely accepted benefits of CSFDs during open repair to prevent and/or rescue patients with SCI. The importance of this issue is underscored by the paucity of data on CSFD practice patterns, limiting the development of practice guidelines. Therefore, the purpose of the present analysis was to evaluate the differences between patients who developed SCI despite preoperative CSFD placement and those treated with therapeutic postoperative CSFD placement. METHODS All elective TEVAR/cEVAR procedures for degenerative aneurysm pathology in the Society for Vascular Surgery Vascular Quality Initiative from 2014 to 2019 were analyzed. CSFD use over time, the factors associated with preoperative prophylactic vs postoperative therapeutic CSFD placement in patients with SCI (transient or permanent), and outcomes were evaluated. Survival differences were estimated using the Kaplan-Meier method. RESULTS A total of 3406 TEVAR/cEVAR procedures met the inclusion criteria, with an overall SCI rate of 2.3% (n = 88). The SCI rate decreased from 4.55% in 2014 to 1.43% in 2018. Prophylactic preoperative CSFD use was similar over time (2014, 30%; vs 2018, 27%; P = .8). After further exclusions to evaluate CSFD use in those who had developed SCI, 72 patients were available for analysis, 48 with SCI and prophylactic CSFD placement and 24 with SCI and therapeutic CSFD placement. Specific to SCI, the patient demographics and comorbidities were not significantly different between the prophylactic and therapeutic groups, with the exception of previous aortic surgery, which was more common in the prophylactic CSFD cohort (46% vs 23%; P < .001). The SCI outcome was significantly worse for the therapeutic group because 79% had documented permanent paraplegia at discharge compared with 54% of the prophylactic group (P = .04). SCI patients receiving a postoperative therapeutic CSFD had had worse survival than those with a preoperative prophylactic CSFD (50% ± 10% vs 71% ± 9%; log-rank P = .1; Wilcoxon P = .05). CONCLUSIONS Prophylactic CSFD use with TEVAR/cEVAR remained stable during the study period. Of the SCI patients, postoperative therapeutic CSFD placement was associated with worse sustained neurologic outcomes and overall survival compared with preoperative prophylactic CSFD placement. These findings highlight the need for a randomized clinical trial to examine prophylactic vs therapeutic CSFD placement in association with TEVAR/cEVAR.

Abstract
INTRODUCTION Study drop-out and attrition from treating clinics is common among persons with chronic health conditions. However, if attrition is associated with adverse health outcomes, it may bias or mislead inferences for health policy and resource allocation. METHODS This retrospective cohort study uses data attained through the Swiss Spinal Cord Injury (SwiSCI) cohort study on persons with spinal cord injury (SCI). Vital status (VS) was ascertained either through clinic medical records (MRs) or through municipalities in a secondary tracing effort. Flexible parametric survival models were used to investigate risk factors for going lost to clinic (LTC) and the association of LTC with subsequent risk of mortality. RESULTS 1924 individuals were included in the tracing study; for 1608 of these cases, contemporary VS was initially checked in the MRs. VS was ascertained for 704 cases of the 1608 cases initially checked in MRs; of the remaining cases (n=904), nearly 90% were identified in municipalities (n=804). LTC was associated with a nearly fourfold higher risk of mortality (HR=3.62; 95% CI 2.18 to 6.02) among persons with traumatic SCI. Extended driving time (ie, less than 30 min compared with 30 min and longer to reach the nearest specialised rehabilitation facility) was associated with an increased risk of mortality (HR=1.51, 95% CI 1.02 to 2.22) for individuals with non-traumatic SCI. CONCLUSION The differential risk of LTC according to sociodemographic and SCI lesion characteristics underscores the importance of accounting for attrition in cohort studies on chronic disease populations requiring long-term care. In addition, given the associated risk of mortality, LTC is an issue of concern to clinicians and policy makers aiming to optimise the long-term survival of community-dwelling individuals with traumatic SCI. Future studies are necessary to verify whether it is possible to improve survival prospects of individuals LTC through more persistent outreach and targeted care.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVES The goal of this study was to assess the impact of multidrug resistant gram-negative organisms (MDRGNOs) on outcomes in those with SCI/D. SETTING VA SCI System of Care, Department of Veterans Affairs, United States. METHODS Multidrug resistance (MDR) was defined as being non-susceptible to ≥1 antibiotic in ≥3 antibiotic classes. Multivariable cluster-adjusted regression models were fit to assess the association of MDRGNOs with 1-year mortality, 30-day readmission, and postculture length of stay (LOS) stratified by case setting patients. Only the first culture per patient during the study period was included. RESULTS A total of 8,681 individuals with SCI/D had a culture with gram-negative bacteria during the study period, of which 33.0% had a MDRGNO. Overall, 954 (10.9%) died within 1 year of culture date. Poisson regression showed that MDR was associated with 1-year mortality among outpatients (IRR: 1.28, 95% CI, 1.06-1.54) and long-term care patients (OR: 2.06, 95% CI, 1.28-3.31). MDR significantly impacted postculture LOS in inpatients, as evidenced by a 10% longer LOS in MDR vs. non-MDR (IRR: 1.10, 95% CI, 1.02-1.19). MDR was not associated with increased 30-day readmission. CONCLUSIONS MDRGNOs are prevalent in SCI/D and MDR may result in poor outcomes. Further attention to prevention of infections, antibiotic stewardship, and management are warranted in this population.

Abstract
OBJECTIVES To determine the rates of emergency department (ED) visits and inpatient hospitalizations for genitourinary (GU) complications after spinal cord injury (SCI) using a national sample; to examine which patient and facility factors are associated with inhospital mortality; and to estimate direct medical costs of GU complications after SCI. DESIGN Retrospective cross-sectional and cost analysis of the 2006 to 2015 National Inpatient Sample and National Emergency Department Sample from the Healthcare Cost and Utilization Project. PARTICIPANTS SCI-related encounters using various International Classification of Disease, Ninth Edition, Clinical Modification diagnosis codes. The inpatient sample included 1,796,624 hospitalizations, and the ED sample included 618,118 treat-and-release visits. MAIN OUTCOME MEASURES The exposure included a GU complication, identified by International Classification of Disease, Ninth Edition, Clinical Modification codes 590-599. The outcomes then included an ED visit or hospitalization, death prior to discharge, and direct medical costs estimated from reported hospital charges. RESULTS For the inpatient sample, we observed a 2.5% annual increase (95% confidence interval [CI], 1.8-3.2) in the proportion of SCI-related hospitalizations with any GU complication from 2006 to 2011, and a lesser rate of increase of 0.9% (95% CI, 0.4-1.4) each year from 2011 to 2015. Age, level of injury, and payer source were correlated to inhospital mortality. The costs of GU-related health care use exceeded $4 billion over the study period. CONCLUSIONS This study shows the rates and economic burden of health care use associated with GU complications in persons with SCI in the United States. The need to develop strategies to effectively deliver health care to the SCI population for these conditions remains great.

Abstract
BACKGROUND The objective of the study was to identify risk factors for poor prognosis of cervical spinal cord injury (SCI) with subaxial cervical fracture-dislocation after surgical treatment. MATERIAL AND METHODS A total of 60 cervical SCI patients with subaxial cervical fracture-dislocation were primarily included in the study from April 2013 to April 2018. All the enrolled subjects received surgical treatment. The enrolled patients with complete follow-up record were divided into 2 groups based on the neural function prognosis: a non-functional restoration group and a functional restoration group. Multivariate regression analysis was performed to identify independent risk factors for poor prognosis of SCI after surgical treatment. RESULTS Fifty-five subjects were included in this study, and the follow-up time ranged from 8.5 to 44.5 months. A total of 25 subjects were categorized into the non-functional restoration group and 30 subjects into the functional restoration group. According to the results of multivariate regression analysis, time from injury to operation (more than 3.8 days), subaxial cervical injury classification (SLIC, score more than 7.5), and maximum spinal cord compression (MSCC, more than 55.8%) are independent risk factors for poor prognosis of SCI after surgical treatment (p<0.05), with AUCs of 0.95 (time from injury to operation), 0.91 (SLIC score), and 0.96 (MSCC). CONCLUSIONS Time from injury to operation (more than 3.8 days), SLIC score (more than 7.5), and MSCC (more than 55.8%) are independent risk factors for poor prognosis of SCI with subaxial cervical fracture-dislocation after surgical treatment.

Abstract
BACKGROUND The knowledge and attitude of nonpsychiatric physicians regarding suicide in spinal cord injury (SCI) patients is important to prevent the accident related to suicide. However, most existing studies have focused on perception of and attitudes among psychiatric physician and mental health care worker.The aim of this study is to investigate awareness and attitude regarding suicide among clinicians treating patients with spinal cord injury, and the necessity of education for suicide prevention. METHODS A total of 29 subjects (N = 29; surgical group n = 17, nonsurgical group n = 12) participated in the study, 6 fellows and 23 residents. They answered a newly revised questionnaire that incorporated 18 items regarding perception of and attitude toward suicide, awareness of suicide in treatment of spinal cord injury patients, and psychiatric consultation; 13 items regarding education and experience; and 4 subjective items regarding their department. A χ test was performed to investigate differences in sociodemographic factors, awareness of and attitude toward suicide, and clinical experience with spinal cord injury patients. Binary logistic regression analysis was used to identify correlation between the questionnaire items. RESULTS There were significant differences between surgical and nonsurgical clinicians in 1 question (Q6) about awareness of and attitude toward suicide (P < .05) and in 2 questions (Q21, Q25) about psychiatric consultation and experience with suicide-related education (P < .01). The correlation analysis revealed significant differences in certain questions among awareness and attitude (P < .05) and age (P < .05) and specialty (P < .01). Two sets of questions (Q16/Q31, Q17/Q26) showed correlation between clinical experience with spinal cord injury patients and awareness of and attitude toward suicide (P < .05). CONCLUSION Education regarding suicide prevention and suicide-related clinical experience with spinal cord injury patients is important for nonpsychiatric clinicians, such as those in the fields of orthopedics, neurosurgery, and rehabilitation medicine.

Abstract
BACKGROUND The Abbreviated Injury Scale (AIS) is an internationally accepted coding system created by the Association for the Advancement of Automotive Medicine, utilized to code traumatic injuries as a function of severity, the latter often defined as mortality risk. Periodic reassessment of that risk is prudent, in light of advances in health care and relationship of nonanatomic factors to death. OBJECTIVE The objective of this study was to reevaluate the risk of death associated with spine fractures with and without neurologic deficit, age factors associated with it, and the impact of hospital coding on the accuracy of these efforts. METHODS Medical records and imaging of patients treated at a level 1 trauma center from 2014 through 2016 with discharge International Classification of Diseases, 10th revision (ICD-10) diagnoses of spinal trauma and spinal cord injury (SCI) were reviewed. Data were collected on demographics, complications, neurologic status, and outcomes. RESULTS Three hundred seventy patients met the criteria for inclusion in this effort. Errors in ICD-10 discharge codes were seen in 45% of the cases, both false positive and negative. One hundred thirty-four patients, with a mean age of 45, were admitted with neurologic deficit. There were 8 SCI-related deaths; 2 were postoperative out of 110 undergoing surgical treatment. All deaths in this group were in patients with upper level SCI, with a mean age of 68. Ten patients had spontaneous neurologic improvement within 24 h. One hundred nineteen patients without deficit had AIS 2 scored fractures; there was one postoperative death out of 47 patients undergoing surgical treatment. One hundred seventeen patients without deficit suffered AIS 3 fractures; 66 underwent surgery without any deaths. There was one nonoperative death. Age and high quadriplegia were the only factors associated with mortality. CONCLUSIONS Mortality risk in patients with deficit was associated more with age at injury than extent of anatomic injury. Spine trauma without neurologic deficit is benign in younger populations and AIS scores could be age adjusted. Mortality risk is higher in high cervical injuries with neurologic deficit and in the elderly. An incidental finding is that demographic studies based solely on discharge ICD coding may contain errors and should be considered critically.

Abstract
INTRODUCTION Trauma presents a significant global health burden. Death resulting from trauma remains high in low income countries despite a steady decrease in developed countries. Analysis of the pattern of death will enable intervention to reduce these deaths from trauma in developing countries. This study aims to present the pattern of trauma-related deaths in the surgical wards of University of Port Harcourt Teaching Hospital (UPTH). METHODS This was a retrospective study of all patients who died from trauma during admission into the surgical wards of UPTH from 2007 to 2012. Data on demography and traumatic events leading to death were collected from surgical wards, the emergency unit, and theatre records and analyzed using SPSS version 16.0. RESULTS Trauma accounted for 219 (42.4%) of the 527 mortalities recorded. Most of the deaths (62.6 %) occurred between 20 and 59 years. There were 148 males (67.6 %). The yearly mortality rates were as follows: 2007(12.3 %); 2008 (16.9%); 2009 (9.1%), 2010 (12.8 %), 2011 (23.3%) and 2012 (25.6%). Most of the patients (91.3%) died within 1 month of admission. The major events leading to deaths were burns 105(47.9%), traumatic brain injuries were 63(28.8%), and spinal cord injuries 21(9.6%). The secondary causes of death were mainly septic shock 112(51.1%); Respiratory failure 60(27.4%); and Multiple organ dysfunction 44(20.1%). CONCLUSION Trauma is a leading cause of mortality in the surgical wards of our hospital. Trauma -related deaths continues to increase over the years. Safe keeping of petroleum products and adherence to traffic rules will reduce these avoidable deaths.

Abstract
The aim of this study is to estimate the risk factors of both respiratory complication (RC) and mortality after acute traumatic cervical spinal cord injury (TCSCI). Between July 2005 and July 2015, in 181 patients (142 males and 39 females; mean age 41.0 years) with acute TCSCI, we compared the difference and odds ratio in RC group (n = 73) with that of non-RC group (n = 108), and also death group (n = 15) and survival group (n = 166). We collected injury-related information after half a year of injury, which is as follows: the causes of injury, time of surgery, ICU (intensive care unit) days, ventilator days, ASIA (American Spinal Injury Association) classification, neurological injury, CIPS (Clinical Pulmonary Infection Score), and BMI (body mass index). Besides these, we gathered the general information such as age, gender, smoking history, and use of steroids. The study compared perioperative parameters; surgery-related and instrumentation- and graft-related complication rates; clinical parameters; patient satisfaction; and radiologic parameters. Variations like gender (odds ratio [OR] = 1.269, 95% confidence interval [CI] [0.609-2.646]), smoking history (OR = 2.902, 95% CI [1.564-5.385]), AIS grade (grade A) (OR = 6.439, 95% CI [3.334-12.434]), neurological level (C1-C4) (OR = 2.714, 95% CI [1.458-5.066]), and steroid use (OR = 2.983, 95% CI [1.276-6.969]) have a facilitated effect on RC. When we estimated surgery-related affection, only the time of surgery and anterior approach compared with posterior has significant difference in RC (P < .05). Between death and survival group, the aspect of age, non-surgical, CPIS, AIS grade, and BMI have statistically significant difference. Survival analysis reveals significant difference in aforementioned groups. In patients suffering from acute TCSCI, those who are old, have long smoking history, complete spinal cord injury, C1-C4, high CPIS, and fat have high incidence of RC and mortality.

Abstract
Long-term survival after severe trauma is rarely addressed in German trauma journals although knowledge of life expectancy and identification of factors contributing to increased mortality are important for lifetime care management, development of service models, and targeting health promotion and prevention interventions. As reliable data in Germany are lacking, we compiled data mainly from the USA and Australia to describe life expectancy, risk factors, and predictors of outcome in patients experiencing traumatic spinal cord injury, traumatic brain injury, and polytrauma. Two years after trauma, life expectancy in all three categories was significantly lower than that of the general population. It depends strongly on severity of disability, age, and gender and is quantifiable. Whereas improvements in medical care have led to a marked decline in short-term mortality, surprisingly long-term survival in severe trauma has not changed over the past 30 years. Therefore, there is need to intensify long-term trauma patient care and to find new strategies to limit primary damage.

Abstract
BACKGROUND With a reported incidence of up to 10% compared to all spinal trauma, spinal injuries in children are less common than in adults. Children can have spine fractures with or without myelopathy, or spinal cord injuries without radiological abnormalities (SCIWORA). METHODS We retrospectively reviewed the cases of children with spinal injuries treated at a level 1 pediatric trauma centre between 1990 and 2013. RESULTS A total of 275 children were treated during the study period. The mean age at admission was 12 ± 4.5 years, and the male:female ratio was 1.4:1. Spinal injuries were more common in children of ages 12-16 years, with most injuries among ages 15-16 years. The top 3 mechanisms of spinal injury were motor vehicle-related trauma (53%), sports (28%) and falls (13%). Myelopathy occurred in 12% and SCIWORA occurred in 6%. The most common spine levels injured were L2-sacrum, followed by O-C2. Associated injuries, including head injuries (29%), and fractures/dislocations (27%) occurred in 55% of children. Overall mortality was 3%. Surgical intervention was required in 14%. CONCLUSION The creation of a pediatric spinal injury database using this 23-year retrospective review helped identify important clinical concepts; we found that active adolescent boys had the highest risk of spine injury, that noncontiguous spine injuries occured at a rate higher than reported previously and that nonaccidental spine injuries in children are underreported. Our findings also emphasize the importance of maintaining a higher index of suspicion with trauma patients with multiple injuries and of conducting detailed clinical and radiographic examinations of the entire spine in children with a known spinal injury.

Abstract
INTRODUCTION In low-income and middle-income countries, people with spinal cord injury (SCI) are vulnerable to life-threatening complications after they are discharged from hospital. The aim of this trial is to determine the effectiveness and cost-effectiveness of an inexpensive and sustainable model of community-based care designed to prevent and manage complications in people with SCI in Bangladesh. METHODS AND ANALYSIS A pragmatic randomised controlled trial will be undertaken. 410 wheelchair-dependent people with recent SCI will be randomised to Intervention and Control groups shortly after discharge from hospital. Participants in the Intervention group will receive regular telephone-based care and three home visits from a health professional over the 2 years after discharge. Participants in the Control group will receive standard care, which does not involve regular contact with health professionals. The primary outcome is all-cause mortality at 2 years. Recruitment started on 12 July 2015 and the trial is expected to take 5 years to complete. ETHICS AND DISSEMINATION Ethical approval was obtained from the Institutional Ethics Committee at the site in Bangladesh and from the University of Sydney, Australia. The study will be conducted in compliance with all stipulations of its protocol, the conditions of ethics committee approval, the NHMRC National Statement on Ethical Conduct in Human Research (2007), the Note for Guidance on Good Clinical Practice (CPMP/ICH-135/95) and the Bangladesh Guidance on Clinical Trial Inspection (2011). The results of the trial will be disseminated through publications in peer-reviewed scientific journals and presentations at scientific conferences. TRIAL REGISTRATION NUMBERS ACTRN12615000630516, U1111-1171-1876.

Abstract
The age— and gender—related signs in 105 injured persons, who died because of combined skeletal trauma, circumstances and character of injuries, causes of death and impact of aggravating factors, were analyzed. There was established, that skeletal trauma have constituted the main cause of death in 10.48% of injured persons only, but as a component of combined injury it aggravates the traumatic disease course and, as a consequence, enhances probability of exitus lethalis. Trustworthy connection between the signs of gender, age, the injuries character and volume was established, what gives a certain information about course of traumatic disease and risk of exitus lethalis

Abstract
OBJECTIVE Nerve growth factor (NGF) has potential in spinal cord injury (SCI) therapy, but limited by the poor physicochemical stability and low ability to cross the blood spinal cord barrier. Novel heparin-poloxamer (HP) thermo-sensitive hydrogel was constructed to enhance the NGF regeneration on SCI. METHOD NGF-HP thermo-sensitive hydrogel was prepared and related characteristics including gelation temperature, rheological behavior and micromorphology were measured. Local NGF delivery to the injured spinal cord was achieved by in situ injection in the injured space. The cellular uptake of NGF-HP hydrogel was evaluated with PC12 cells in vitro. Pathologic characteristics and neuron regeneration effects on the SCI rats were studied to evaluate the enhanced therapy of NGF-HP hydrogel. Endoplasmic reticulum (ER) stress-induced apoptosis was analyzed to explore the related mechanism in SCI regeneration. RESULTS NGF-HP hydrogel showed good morphology and stable bioactivity of NGF in vitro. NGF-HP hydrogel combined treatment significantly enhanced the efficiency of NGF cellular uptake (P<0.05) without obvious cytotoxicity. Significant improvements in both neuron functions and tissue morphology on the SCI rats were observed in NGF-HP hydrogel group. Compared with free HP hydrogel and NGF treatment groups, NGF-HP hydrogel group showed significant inhibition on the formation of glial scars in the extreme crushed rat SCI model. The neuroprotective effects of NGF-HP were related to the inhibition of chronic ER stress-induced apoptosis. CONCLUSIONS HP hydrogel combined with orthotopic injection technique might be an effective method to deliver NGF into the injured site, which will provide an effective strategy for SCI regeneration. STATEMENT OF SIGNIFICANCE Spinal cord injury (SCI) is a devastating condition that can lead to sudden loss of sensory and autonomic function. Current treatment includes decompression surgery, injury stabilization, secondary complications prevention and rehabilitation. However, neurological recovery is limited. Nerve growth factor (NGF) has potential in SCI therapy, but limited by the poor physicochemical stability and low ability to cross the blood spinal cord barrier. Hydrogels have good affinity and compatibility to biological tissue. In this study, we developed a novel heparin-poloxamer (HP) thermo-sensitive hydrogel to enhance the spinal cord regeneration of NGF. From SCI rat experiment, HP hydrogel combined with orthotopic injection technique showed best neuroprotective effects among experimental groups. This novel combined technique will provide an effective strategy for SCI regeneration.

Abstract
BACKGROUND A gap exists in the current knowledge regarding the epidemiology of traumatic spinal cord injury (TSCI) in a statewide population. OBJECTIVE To describe population-based epidemiology and trend of TSCI in persons 22 years and older in South Carolina over a 15-year period from 1998 through 2012. METHODS Data on patients with TSCI were obtained from ongoing statewide TSCI surveillance and follow-up registry. Deaths were ascertained by linking surveillance files and the multiple cause-of-death dataset. Descriptive analyses were completed, and incidence and mortality rates were calculated based on the civilian adult population of the state. RESULTS Over the 15 years, 3,365 persons with incident TSCI were discharged alive from acute care hospitalization, of whom 555 died during the period of observation. Age-standardized cumulative mortality rate was 14 per million, and the average incidence rate was estimated at 70.8 per million population per year. Age-standardized incidence rate of TSCI increased significantly from 66.9 in 1998 to 111.7 per million in 2012. Standardized incidence rates were significantly higher among non-Whites and males. Motor vehicle crashes and falls were the leading causes, accounting for nearly 70% of TSCI. CONCLUSIONS Standardized incidence and mortality rates of TSCI in South Carolina are higher than reported rates for the US population. Motor vehicle crashes and falls are the leading causes of TSCI. There was a significant increase in the overall trend of the incidence rates over the 15 years. A well-coordinated preventive strategy is needed to reduce incidence and improve survival of persons with TSCI.

Abstract
IMPORTANCE Acute traumatic spinal cord injury results in disability and use of health care resources, yet data on contemporary national trends of traumatic spinal cord injury incidence and etiology are limited. OBJECTIVE To assess trends in acute traumatic spinal cord injury incidence, etiology, mortality, and associated surgical procedures in the United States from 1993 to 2012. DESIGN, SETTING, AND PARTICIPANTS Analysis of survey data from the US Nationwide Inpatient Sample databases for 1993-2012, including a total of 63,109 patients with acute traumatic spinal cord injury. MAIN OUTCOMES AND MEASURES Age- and sex-stratified incidence of acute traumatic spinal cord injury; trends in etiology and in-hospital mortality of acute traumatic spinal cord injury. RESULTS In 1993, the estimated incidence of acute spinal cord injury was 53 cases (95% CI, 52-54 cases) per 1 million persons based on 2659 actual cases. In 2012, the estimated incidence was 54 cases (95% CI, 53-55 cases) per 1 million population based on 3393 cases (average annual percentage change, 0.2%; 95% CI, -0.5% to 0.9%). Incidence rates among the younger male population declined from 1993 to 2012: for age 16 to 24 years, from 144 cases/million (2405 cases) to 87 cases/million (1770 cases) (average annual percentage change, -2.5%; 95% CI, -3.3% to -1.8%); for age 25 to 44 years, from 96 cases/million (3959 cases) to 71 cases/million persons (2930 cases), (average annual percentage change, -1.2%; 95% CI, -2.1% to -0.3%). A high rate of increase was observed in men aged 65 to 74 years (from 84 cases/million in 1993 [695 cases] to 131 cases/million [1465 cases]; average annual percentage change, 2.7%; 95% CI, 2.0%-3.5%). The percentage of spinal cord injury associated with falls increased significantly from 28% (95% CI, 26%-30%) in 1997-2000 to 66% (95% CI, 64%-68%) in 2010-2012 in those aged 65 years or older (P < .001). Although overall in-hospital mortality increased from 6.6% (95% CI, 6.1%-7.0%) in 1993-1996 to 7.5% (95% CI, 7.0%-8.0%) in 2010-2012 (P < .001), mortality decreased significantly from 24.2% (95% CI, 19.7%-28.7%) in 1993-1996 to 20.1% (95% CI, 17.0%-23.2%) in 2010-2012 (P = .003) among persons aged 85 years or older. CONCLUSIONS AND RELEVANCE Between 1993 and 2012, the incidence rate of acute traumatic spinal cord injury remained relatively stable but, reflecting an increasing population, the total number of cases increased. The largest increase in incidence was observed in older patients, largely associated with an increase in falls, and in-hospital mortality remained high, especially among elderly persons.

Abstract
OBJECTIVE Identify factors associated with chest illness and describe the relationship between chest illness and mortality in chronic spinal cord injury (SCI). DESIGN Cross-sectional survey assessing chest illness and a prospective assessment of mortality. METHODS Between 1994 and 2005, 430 persons with chronic SCI (mean ± SD), 52.0 ± 14.9 years old, and ≥4 years post SCI (20.5 ± 12.5 years) underwent spirometry, completed a health questionnaire, and reported any chest illness resulting in time off work, indoors, or in bed in the preceding 3 years. Deaths through 2007 were identified. Outcome measures Logistic regression assessing relationships with chest illness at baseline and Cox regression assessing the relationship between chest illness and mortality. RESULTS Chest illness was reported by 139 persons (32.3%). Personal characteristics associated with chest illness were current smoking (odds ratio =2.15; 95% confidence interval =1.25-3.70 per each pack per day increase), chronic obstructive pulmonary disease (COPD) (3.52; 1.79-6.92), and heart disease (2.18; 1.14-4.16). Adjusting for age, subjects reporting previous chest illness had a non-significantly increased hazard ratio (HR) for mortality (1.30; 0.88-1.91). In a multivariable model, independent predictors of mortality were greater age, SCI level and completeness of injury, diabetes, a lower %-predicted forced expiratory volume in 1 second, heart disease, and smoking history. Adjusting for these covariates, the effect of a previous chest illness on mortality was attenuated (HR = 1.15; 0.77-1.73). CONCLUSION In chronic SCI, chest illness in the preceding 3 years was not an independent risk factor for mortality and was not associated with level and completeness of SCI, but was associated with current smoking, physician-diagnosed COPD, and heart disease history.

Abstract
The inability to effectively control microbial infection is a leading cause of morbidity and mortality in individuals affected by spinal cord injury (SCI). Available evidence from clinical studies as well as animal models of SCI demonstrate that increased susceptibility to infection is derived from disruption of central nervous system (CNS) communication with the host immune system that ultimately leads to immunodepression. Understanding the molecular and cellular mechanisms governing muted cellular and humoral responses that occur post-injury resulting in impaired host defense following infection is critical for improving the overall quality of life of individuals with SCI. This review focuses on studies performed using preclinical animal models of SCI to evaluate how injury impacts T and B lymphocyte responses following either viral infection or antigenic challenge.

Abstract
OBJECTIVE To access the feasibility of reducing tracheostomy rates in patients with complete cervical spinal cord injury through a systemic respiratory management mode. METHODS A retrospective review was performed for 239 patients on a systemic respiratory management mode after complete cervical spinal cord injury in Shanghai Changzheng Hospital from 2006 to 2012. Their demographic and clinical data, including age, gender, cause of injury, level of cervical spinal cord injuries, surgical approaches, tracheostomy rates and mortality rates, were collected and analyzed. Tracheostomy rates were compared with those of patients with complete cervical spinal cord injury. Tracheostomy rates were compared with those patients with complete cervical spinal cord injury from 1991 to 2005. The new respiratory management mode for patients with severe cervical spinal cord injury included maintaining adequate energy and water for patients, relieving bronchospasm, loosening phlegm, strengthening body-turning and backslapping, sputum aspiration with suction tube through nasal cavity or bronchofibroscope, strengthening deep breath and cough training, strict control of tracheostomy indications and short-term postoperative intubation reserving if necessary. RESULTS 32 patients were implemented tracheostomy. The tracheostomy rate was 13.4%. 10 patients died, the mortality rate was 4.18%. However, the tracheostomy rate was 19.1% and mortality rate 21.4% from 1991 to 2005. The tracheostomy rate was significantly lower than before and survival rate improved significantly. CONCLUSION The systemic respiratory management mode can effectively reduce tracheostomy rate of patients with complete cervical spinal cord injury and improve their survival rate.

Abstract
OBJECTIVE To evaluate the value of preventive tracheotomy in patients with acute cervical spinal cord injury. METHODS A retrospective analysis was performed on 54 cases of severe C4-C8 cervical spinal cord injury patients undergoing anterior fixation. They were classified as A and B according to the criteria of American Spinal Injury Association. And no tracheotomy was performed preoperatively. The patients with a high risk of dyspnea and with an indication for preventive tracheotomy received a preventive tracheotomy right after anterior fixation. 11 cases were classified into tracheotomy group and 43 cases were in non-tracheotomy group. The preoperative and hospital stays, incidence of hypoxemia and pulmonary infection, incidence of surgical incision site infection and mortality were analyzed between two groups. RESULTS The preoperative and hospital stays of tracheotomy group were shorter than those of non-tracheotomy group (2.9 ± 1.2 vs 5.7 ± 4.4 days, 10.3 ± 4.0 vs 16.5 ± 9.2 days). The incidence of hypoxemia was lower in tracheotomy group (9.1% vs 44.2%). There was difference existed between two groups. 44.2% patients in the non-tracheotomy group underwent tracheotomy or endotracheal intubation for dyspnea and hypoxemia. There was no significant difference between two groups in the incidence of pulmonary infection (9.1% vs 7.0%) or surgical incision site infection (0 vs 2.3%). The mortality of non-tracheotomy group was 3.07 folds of that of tracheotomy group (9.1% vs 27.9%). But there was no significant statistical difference. CONCLUSION The preventive tracheotomy is an effective solution for the patients with respiratory compromises, a high risk of dyspnea and with an indication for preventive tracheotomy. The preventive tracheotomy for severe cervical spinal cord can improve respiratory function effectively and fixation may be performed earlier. And there are lower rates of mortality and infection.

Abstract
AIMS Cervical spinal cord injury is a major cause of fatality among trauma victims. Unlike developed countries, national spinal cord injury database is not maintained in India. Paucity of data hampers the understanding of epidemiology of the event in India. So, this study was conducted to ascertain the epidemiological pattern of death due to cervical spinal cord injury and to identify the risk factors; also to find the association of vertebral injuries with various epidemiological parameters. METHODS Among autopsies conducted in Burdwan Medical College and Hospital from 2000 to 2010, cases with autopsy report mentioning "death due to cervical spinal cord injury" either primary or secondary were included in the study. It was a retrospective observational study based on autopsy report. RESULTS 536 cases met the inclusion criteria. Among them 89.4% were male and 10.6% were female; 63.8% victims were young adults (20-39 years). Mean (plus or minus S.D.) age was 33.5 years (plus or minus 12.8). All, apart from 5.4%, suffered from single segment injury with commonest site being C3-C4 (37.3%). Highest number of trauma occurred between 6 am to 9 am, 56.6% of the victims died before hospitalisation. Commonest mode of injury was road traffic accident (52.2%) followed by fall from height (25.0%); 53.7% cases had vertebral fracture with dislocation, 34.3% had only vertebral fracture. Only dislocation was significantly high up to 19 years age (p<0.001) and among females (p=0.029). All elderly suffered from fracture. CONCLUSIONS This study revealed an unusually high male:female ratio with much representation of the younger age groups in the injuries in comparison to other parts of world. In absence of national database, this result can be used as a surrogate data.

Abstract
This study presents an analysis of crash characteristics of motorcyclists who sustained spinal injuries in motorcycle crashes. The aim of the study is to identify the salient crash characteristics that would help explain spinal injury risks for motorcyclists. Data were retrospectively collected from police case reports that were archived at MIROS from year 2005 to 2007. The data were categorized into two subcategories; the first group was motorcycle crashes with spinal injury (case) and the second group was motorcycle crashes without spinal injury (control). A total of 363 motorcyclists with spinal injury and 873 motorcyclists without spinal injury were identified and analyzed. Descriptive analysis and multivariate analysis were performed in order to determine the odds of each characteristic in contributing to spinal injury. Single vehicle crash, collision with fixed objects and crash configuration were found to have significant influence on motorcyclists in sustaining spinal injury (p<0.05). Although relatively few than other impact configurations, the rear-end impacted motorcyclist shows the highest risk of spinal injury. Helmets have helped to reduce head injury but they did not seem to offer corresponding protection for the spine in the study. With a growing number of young motorcyclists, further efforts are needed to find effective measures to help reduce the crash incidents and severity of spinal injury. In sum, the study provides some insights on some vital crash characteristics associated with spinal injury that can be further investigated to determine the appropriate counter-measures and prevention strategies to reduce spinal injury.

Abstract
To improve clinicians' ability to predict outcome after spinal cord injury (SCI) and to help classify patients within clinical trials, we have created a novel prediction model relating acute clinical and imaging information to functional outcome at 1 year. Data were obtained from two large prospective SCI datasets. Functional independence measure (FIM) motor score at 1 year follow-up was the primary outcome, and functional independence (score ≥ 6 for each FIM motor item) was the secondary outcome. A linear regression model was created with the primary outcome modeled relative to clinical and imaging predictors obtained within 3 days of injury. A logistic model was then created using the dichotomized secondary outcome and the same predictor variables. Model validation was performed using a bootstrap resampling procedure. Of 729 patients, 376 met the inclusion criteria. The mean FIM motor score at 1 year was 62.9 (±28.6). Better functional status was predicted by less severe initial American Spinal Injury Association (ASIA) Impairment Scale grade, and by an ASIA motor score >50 at admission. In contrast, older age and magnetic resonance imaging (MRI) signal characteristics consistent with spinal cord edema or hemorrhage predicted worse functional outcome. The linear model predicting FIM motor score demonstrated an R-square of 0.52 in the original dataset, and 0.52 (95% CI 0.52,0.53) across the 200 bootstraps. Functional independence was achieved by 148 patients (39.4%). For the logistic model, the area under the curve was 0.93 in the original dataset, and 0.92 (95% CI 0.92,0.93) across the bootstraps, indicating excellent predictive discrimination. These models will have important clinical impact to guide decision making and to counsel patients and families.

Abstract
Research investigators often choose to euthanize mice by cervical dislocation (CD) when other methods would interfere with the aims of a research project. Others choose CD to assure death in mice treated with injected or inhaled euthanasia agents. CD was first approved for mouse euthanasia in 1972 by the AVMA Panel on Euthanasia, although scientific assessment of its humaneness has been sparse. Here we compared 4 methods of spinal dislocation--3 targeting the cervical area (CD) and one the thoracic region--in regard to time to respiratory arrest in anesthetized mice. Of the 81 mice that underwent CD by 1 of the 3 methods tested, 17 (21%) continued to breathe, and euthanasia was scored as unsuccessful. Postmortem radiography revealed cervical spinal lesions in 5 of the 17 cases of unsuccessful CD euthanasia. In addition, 63 of the 64 successfully euthanized mice had radiographically visible lesions in the high cervical or atlantooccipital region. In addition, 50 of 64 (78%) mice euthanized successfully had radiographically visible thoracic or lumbar lesions or both. Intentionally creating a midthoracic dislocation in anesthetized mice failed to induce respiratory arrest and death in any of the 18 mice subjected to that procedure. We conclude that CD of mice holds the potential for unsuccessful euthanasia, that anesthesia could be valuable for CD skills training and assessment, and that postmortem radiography has minimal promise in quality-control assessments.

Abstract
BACKGROUND Well-organised and efficient prehospital transport is associated with an improved outcome in trauma patients. In Nigeria there is a paucity of information on prehospital transport of spinal cord-injured patients and its relation to mortality. OBJECTIVE To determine whether prehospital transportation is a predictor of mortality in spinal cord-injured patients in Nigeria. DESIGN Prospective cohort study. METHODS Prehospital transport-related conditions, injury-to-arrival intervals and persons who brought spinal cord-injured patients to the casualty departments at the University of Abuja Teaching Hospital, Gwagwalada, and the National Orthopaedic Hospital, Lagos, were noted. Data were analysed using descriptive statistics, the chi-square test and multiple logistic regressions. MAIN OUTCOME MEASURES Mortality within 6 weeks of admission. Results. During the review period, 168 patients with spinal cord injury presented to the casualty departments. Most presented 24 hours or more after the injury (67.9%) and were brought to casualty by their relatives (58.3%). Saloon cars were the most common mode of transportation (54.2%), most patients (55.4%) lying on their back during transfer. The majority of the patients (75%) had been taken to at least one other hospital before arriving at our casualty departments. The mortality rate was 16.7%. Multivariate analysis after adjusting for age, gender and means of transportation revealed that age (odds ratio (OR) 63.41, 95% confidence interval (CI) 9.24 - 43.53), a crouched position during transfer (OR 23.52, 95% CI 7.26 - 74.53), presentation after 24 hours (OR 5.48, 95% CI 3.20 - 16.42) and multiple hospital presentations (OR 7.94, 95% CI 1.89 - 33.43) were associated with death within 6 weeks of admission. CONCLUSION Well-organised and efficient prehospital transport would reduce mortality in spinal cord-injured patients. Providing information on prehospital transport would also reduce mortality.

Abstract
This study deals with deaths during the period 2004 to 2009 that occurred during the use of a vehicle known as pat-pat, which is an unusual vehicle, similar to a tractor-trailer used in agricultural production and transportation The records of crime scene investigation and autopsies of 28 cases of death due to pat-pat-related crushes were evaluated. Of all cases, 60.7 percent were drivers and the remaining 39.3% were passengers. The most common cause of death (in 39.3% of cases) was brain-spinal cord injury due to blunt trauma of the head and neck. Implementing legislation regarding safety measures or limitation of the use for transportation should be performed for pat-pats, of which thousands are currently in use.

Abstract
OBJECTIVE To evaluate the impact of age (<or≥65 ans) on hospital mortality in traumatic spinal cord injury requiring intensive care. DESIGN Retrospective, monocenter. PATIENTS AND METHODS A total of 131 patients greater or equal to 15 years (<65 years, n=109 and ≥65 years, n=22) was analyzed (cervical, n=71; thoracolumbar, n=60), over a 10 years period (1998-2008). The hospital and long-term mortality were studied. The risks factors of death were searched by a uni- and multivariate analysis. Intensive care unit (ICU) discharge and long-term neurological recovery, and long-term functional independence measure (FIM) were assessed. RESULTS Hospital mortality was increased in patients greater or equal to 65 years (41% vs 6%, P<0.001) and long term mortality was not different between the two groups (31% vs 12%, P=0.150). The risks factors of death were age (HR=3.44; IC 95%: 1.53-7.72, P=0.028), previous coronary disease (HR=3.64; IC 95%: 1.25-10.65; P=0.018) and fall injury (HR=2.40; IC 95%: 1.15-5.00, P=0.020). Among survivors, incompletes forms (Frankel B, C, D, E) were significantly more frequent in older patients at ICU discharge and long term follow up. At long term, FIM was similar in the two groups except a better sphincter control in patient greater or equal to 65 years. CONCLUSION Mortality rate of older people (≥65 years) were greater than those in younger people, mainly caused by an increased hospital mortality. Among survivors, the neurological recovery was better in patients' greater or equal to 65 years, and was associated with a functional status at least comparable than in the youngest patients.

Abstract
OBJECTIVE To evaluate the association of health status, secondary health conditions, hospitalizations, and risk of mortality and life expectancy (LE) after spinal cord injury (SCI). DESIGN Prospective cohort study. SETTING Preliminary data were collected from a specialty hospital in the Southeastern United States, with mortality follow-up and data analysis conducted at a medical university. PARTICIPANTS Adults with traumatic SCI (N=1361), all at least 1-year postinjury at the time of assessment, were enrolled in the study. There were 325 deaths. After elimination of those with missing data on key variables, there were 267 deaths and 12,032 person-years. INTERVENTIONS None. MAIN OUTCOME MEASURES The mortality status was determined by routine follow-up using the National Death Index through December 31, 2008. A logistic regression model was developed to estimate the probability of dying in any given year using person-years. RESULTS A history of chronic pressure ulcers, amputations, a depressive disorder, symptoms of infections, and being hospitalized within the past year were all predictive of mortality. LE estimates were generated using the example of a man with noncervical, nonambulatory SCI. Using 3 age examples (20, 40, 60y), the greatest estimated lost LE was associated with chronic pressure ulcers (50.3%), followed by amputations (35.4%), 1 or more recent hospitalizations (18.5%), and the diagnosis of probable major depression (18%). Symptoms of infections were associated with a 6.7% reduction in LE for a 1 SD increase in infectious symptoms. CONCLUSIONS Several secondary health conditions represent risk factors for mortality and diminish LE after SCI. The presence of 1 or more of these factors should be taken as an indicator of the need for intervention.

Abstract
BACKGROUND The Disability-Adjusted Life Year (DALY) was designed by the World Health Organization (WHO) to measure, compare, and analyze the burden of various diseases. To the best of our knowledge, this is the first study on the assessment of burden of traumatic spinal fracture (TSF) in an Iranian community. We estimated burden of TSF includes both isolated (iTSF) and associated injuries related to traumatic spinal fractures (aTSF) in Tehran, the capital of Iran, for the year 2006-2007 using DALYs. METHODS Burden of TSF was estimated based on information provided by the national data on Iranian trauma, data from the WHO, and literature data using disease modeling (DISMOD). Incidence of TSF and associated injuries were obtained from two population based studies and National Trauma Data Bank in Iran, while duration, and relative risk of mortality (RRM) were obtained from WHO data and the literature. The incidence, duration, and relative risk of mortality (RRM) were used to calculate DALY for TSF. To calculate DALY, the years of life lost because of premature mortality (YLL) were added to the number of years lost because of disability (YLD). DALYs were calculated separately for both iTSF and aTSF. In-hospital YLD and post-hospital YLL for iTSF and in-hospital YLL and YLD were calculated for aTSFs. RESULTS TSF incidence was 16.35 (95%CI: 3.4-48.0) per 100,000. The incidence of TSF in males was more than twice that of females. The largest DALYs were seen in 15-29 years. The highest burden of associated injuries of TSF was related to spinal cord and head injury. DALYs for aTSF were estimated to be 2496.9 years (32.0 DALY/100,000 population). The YLD and YLL were almost similar. Total DALY for iTSF and aTSF was 2568.9 years (32.92 DALY/100,000 population). Based on the risk extracted from the literature, post-hospital increased risk of mortality was increased by 1318 DALY (16.89 DALY/100,000 population). CONCLUSION This study showed a considerable burden for TSFs mainly due to associated injuries and increased lifelong RRM in patients with TSF.

Abstract
BACKGROUND There have been many reports on the problems of spinal cord injury (SCI) in Nigeria but few have reported on the complications and causes of death in spinal cord injured patients. OBJECTIVE The objective of this study was to determine the complications, causes of death and associated risk factors in patients with SCI within six months post injury. METHODS Patients were retrospectively identified from the hospital trauma database from January 1997 to December 2007. Complications and cause of death within the first six months of SCI were determined along with associated risk factors. RESULTS Five hundred and eighty-two patients were eligible for analyses and data were obtained for 422 (72.5%) patients with a mean age of 37.2 (±14.2) years at six months follow-up. Muscle spasms 417 (98.8%) and neurogenic pain 382 (94.5%) were the main complications noted. The mortality during the review period was 144 (34.1%). Respiratory failure (44.4%) was the commonest cause of death. The independent predictors of mortality were mainly age, GCS<9, Frankel Type A at presentation and cervical spine injury (CSI) and while CSI and Frankel Type A injury were the main predictors of complications. CONCLUSION Most common complication and cause of death following SCI are muscle spasm and respiratory failure respectively. The risk factors associated with mortality are age, GCS<9, cervical spinal injury, and complete neurologic injury and those for complications were cervical spinal injury and Frankel Type A injury.

Abstract
The spectrum of critical illness-related corticosteroid insufficiency (CIRCI) in trauma is not fully defined. This study describes our trauma experience with hydrocortisone-treated patients experiencing CIRCI. We conducted a 5-year retrospective analysis from a Level II trauma center using biochemical and clinical criteria for adrenal insufficiency. Seventy patients met the inclusion criteria for CIRCI. There was a 34 per cent mortality rate despite therapy. Nonsurvivors were older with larger admission base deficits and experienced higher rates of sepsis, bacteremia, and pneumonia. Nonsurvivors had prolonged vent days (mean 53 ± 64 days) when compared with survivors (mean 30 ± 22 days; P = 0.029). Renal replacement therapy was a strong predictor of mortality. Spinal cord-injured patients had high Injury Severity Scores (mean 34 ± 18), elevated baseline cortisol levels (mean 56 ± 84 vs. 18 ± 14; P = 0.004), and required prolonged duration of steroid therapy (30 ± 52 vs. 15 ± 15 days; P = 0.080) when compared with the nonspinal cord-injured group. Our data suggest that CIRCI in trauma is associated with significant mortality and morbidity even when patients are treated appropriately.

Abstract
BACKGROUND Previous studies of glycemic control in non-neurologic ICU patients have shown conflicting results. The purpose was to investigate whether intensive insulin therapy (IIT) to keep blood glucose levels from 80 to 110 mg/dl or conventional treatment to keep levels less than 151 mg/dl was associated with a reduction of mortality and improved functional outcome in critically ill neurologic patients. METHODS Within 24 h of ICU admission, mechanically ventilated adult neurologic patients were enrolled after written informed consent and randomized to intensive or conventional control of blood glucose levels with insulin. Primary outcome measure was death within 3 months. Secondary outcome measures included 90-day modified Rankin scale (mRS) score, ICU, and hospital LOS. RESULTS 81 patients were enrolled. The proportion of deaths was higher among IIT patients but this was not statistically significant (36 vs. 25%, P = 0.34). When good versus poor outcome at 3 months was dichotomized to mRS score 0-2 versus 3-6, respectively, there was no difference in outcome between the two groups (76.2 vs. 75% had a poor 3-month outcome, P = 1.0). There was also no difference in ICU or hospital LOS. Hypoglycemia (<60 mg/dl) and severe hypoglycemia (<40 mg/dl) were more common in the intensive arm (48 vs. 11%, P = 0.0006; and 4 vs. 0%, P = 0.5, respectively). CONCLUSION There was no benefit to IIT in this small critically ill neurologic population. This is the first glycemic control study to specifically examine both critically ill stroke and traumatic brain injury (TBI) patients and functional outcome. Given these results, IIT cannot be recommended over conventional control.

Abstract
OBJECTIVE To evaluate the association of household income and formal education with risk of mortality after spinal cord injury (SCI). DESIGN Cohort study. SETTING Twenty hospitals designated as Model SCI Systems of care in the United States. PARTICIPANTS Adults (N=8027) with traumatic SCI, seen in one of the Model SCI Systems, who had at least 1 follow-up assessment between 1995 and 2006. All participants were at least 1 year postinjury at the time of assessment. There were 57,957 person-years and 1036 deaths. The follow-up period started with the first assessment between 1995 and 2006 and went until either the date of death or March 2009. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Mortality status was determined by routine follow-up supplemented by using the Social Security Death Index. A logistic regression model was developed to estimate the chance of dying in any given year. RESULTS Educational status and income were significantly predictive of mortality after adjusting for age, sex, race, and severity of injury. Compared with those with household income of $75,000 or greater, the odds of mortality was greater for those who had income between $25,000 and $75,000 (1.61) and still higher for those with less than $25,000 a year (2.41). Life expectancy differed more as a function of household income than the economic subscale of the Craig Handicap Assessment and Reporting Technique. CONCLUSION There was a clear gradation in survival based on familial income (high, middle, low), not just an effect of the lowest income.

Abstract
INTRODUCTION The purpose of this study was to analyze linked crash and hospital data to determine the effect that enactment of a standard enforcement safety belt law in Ohio would have on hospital charges and direct medical costs due to motor-vehicle crashes, focusing on the impact to the state's Medicaid system. METHOD The linkage and analysis was conducted as part of the Ohio Crash Outcome Data Evaluation System (CODES) program. Current safety belt usage in Ohio stands at 82% with its secondary enforcement safety belt law. RESULTS Assuming an increase in usage to 92% through standard enforcement, over $15.3 million in medical costs to Medicaid for injuries that occur in a single year could be prevented over a 10-year period. Cumulative savings could reach more than $91.2 million during the 10-year period. In addition, 161 fatalities could have been prevented in one year had all unbelted occupants who sustained a fatal injury instead chosen to wear their safety belt. SUMMARY AND IMPACT ON INDUSTRY: Clearly, substantial progress can be made in reducing the number of deaths and injuries, as well as medical costs associated with motor-vehicle crashes, by strengthening safety belt laws and increasing safety belt usage in Ohio.

Abstract
OBJECTIVE To identify the association of 2 distinct psychologic constructs, personality and purpose in life (PIL), with risk of early mortality among persons with spinal cord injury (SCI). DESIGN Prospective cohort study with health data collected in late 1997 and early 1998 and mortality status ascertained in December 2005. SETTING A large rehabilitation hospital in the southeastern United States. PARTICIPANTS Adults (N=1386) with traumatic SCI, at least 1 year postinjury. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES We first evaluated the significance of a single psychologic predictor (a total of 6 scales) while controlling for biographic and injury predictors using Cox proportional hazards modeling and subsequently built a comprehensive model based on an optimal group of psychologic variables. RESULTS There were a total of 224 (16.2%) observed deaths in the full sample. The total number of deaths was reduced to 164 in the final statistical model (of 1128 participants) because of missing data. All 6 psychologic factors were statistically significant in the model that was adjusted for biographic and injury factors, whereas only 3 psychologic factors were retained in the final comprehensive model, including 2 personality scales (Impulsive Sensation Seeking, Neuroticism-Anxiety) and the PIL scale. The final comprehensive model only modestly improved the overall prediction of survival compared with the model with only biographic and injury variables, because the pseudo-R(2) increased from 0.121 to 0.129, and the concordance increased from 0.730 to 0.747. CONCLUSIONS The results affirm the importance of psychologic factors in relation to survival after SCI.

Abstract
OBJECTIVE To analyze clinical characteristics and therapeutic efficacy of acute traumatic central cervical spinal-cord syndrome without fracture and dislocation,and to investigate its treatment methods. METHODS Clinical data of 47 cases with acute traumatic central cervical spinal-cord syndrome without fracture and dislocation were retrospectively analyzed. There were 3 female and 44 male,with a mean age of 56.2 years (ranging from 46 to 73 years). According to Frankel classification, 30 cases were grade B, 14 cases were grade C and 3 cases were grade D. Forty-two cases were treated without operation, and 5 cases which had significant compression factors or segmental instability were treated with surgical treatment. Among them, 3 cases were treated through anterior approach and 2 cases were treated through posterior approach. Causes of injuries, mechanisms of injuries,findings of imaging, functional impairment of nerve,methods of treatment,and therapeutic efficacy were analyzed. RESULTS The average followed-up time was 12 months (ranging form 3 to 84 months), 2 cases of non-operation were dead and 6 were loss. Three months after treatment, some complications occurrenced on 7 patients of non-operation. The majority bequeathed different degree impairment of intrinsic muscles of hands. CONCLUSION Reduction and fixation through the pedicle of fractured vertebra is an effective therapeutic options to treat the thoracolumbar burst fractures and desearved clinical study and expansion.

Abstract
OBJECTIVE To test hypothesized relationships between multiple health parameters and mortality among persons with spinal cord injury (SCI) while controlling for variations in biographical and injury characteristics. DESIGN Prospective cohort study with health data collected in late 1997 and early 1998 and mortality status ascertained in December 2005. SETTING A large rehabilitation hospital in the Southeastern United States. PARTICIPANTS A total of 1389 adults with traumatic SCI, at least 1 year postinjury. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES The primary outcome was time from survey to mortality (or time of censoring). Mortality status was determined using the National Death Index and the Social Security Death Index. There were 225 deaths (16.2%) by December 31, 2005. RESULTS Cox proportional hazards modeling identified several significant health predictors of mortality status, while controlling for biographic and injury factors. Two sets of analyses were conducted--the first identifying the significance of a single variable of interest and the second analysis building a comprehensive model based on an optimal group of variables. Multiple types of health conditions were associated with mortality. The best set of health predictors included probable major depression, surgeries to repair pressure ulcers, fractures and/or amputations, symptoms of infections, and days hospitalized. Inclusion of these variables, along with a general health rating, improved prediction of survival compared with biographic and injury variables alone, because the pseudo R(2) increased from .12 to .18 and the concordance from .730 to .776. CONCLUSIONS In addition to secondary conditions that have been the traditional focus of prevention efforts (eg, pressure ulcers, urinary tract infections), amputations, fractures, and depressive symptoms were associated with higher risk for mortality; however, further research is needed to identify the association of specific conditions with causes of death and to determine whether interventions can modify these conditions and ultimately improve survival.

Abstract
BACKGROUND The outcomes of spinal cord injuries (SCI) have improved over the last decades. OBJECTIVES Update on outcomes following SCI in Israel. METHODS Data on 259 SCI patients admitted for rehabilitation between 1992 and 2003 were collected. Survival rates were estimated using the product limit (Kaplan-Meyer) method and their association with risk factors was analyzed with the Cox Proportional Hazard model. Neurological recovery was determined by the change in Frankel grades during rehabilitation, and compared with data from a previous study using the chi2 test. Effects on neurological recovery were examined using logistic regression. Effects on length of stay (LOS) were assessed by ANOVA. RESULTS The number of SCI patients approximately doubled during the 1990s. Survival rate was 88% and 86.3%, 5 and 10 years respectively after injury. Survival was negatively associated with age (p < 0.001) and with high spinal level of injury (p < 0.001). Thirty eight percent of patients with Frankel grades A, B, or C (SCI that do not allow functioning) recovered to grades D or E (that allow functioning). Average LOS was 135 days. LOS was positively associated with Frankel grade and negatively with recent SCI onset. CONCLUSIONS The demand for rehabilitation after SCI increased significantly in the studied decade. In Israel, survival and neurological recovery rates after SCI rehabilitation are close to those reported in other countries. Despite the decrease in LOS, in recent years, survival is at least as long as before, and neurological recovery has improved significantly.

Abstract
BACKGROUND Traumatic injury in the elderly is an increasing problem and studies have shown that elderly patients (>/=65 years old) with cervical spine fractures and spinal cord injury (SCI) carry a mortality rate of 21% to 30%. However, little has been described with regard to outcomes for elderly patients with isolated cervical spine fractures (ICSF). HYPOTHESIS Outcomes for elderly patients with ICSF will be similar to elderly patients with cervical fractures and associated traumatic injuries (ATI) or SCI. METHODS A 9-year retrospective analysis was performed on all patients >/=65 years old admitted to a level I trauma center with any cervical spine fracture. Primary outcomes were defined as favorable (discharge to home or rehabilitation hospital) or unfavorable (death, discharge to a long-term acute care facility, or a skilled nursing facility). ICSF was defined as those fractures without ATI or SCI. Long-term mortality data were gathered using the Social Security Death Index. RESULTS A total of 177 patients with mean age of 78 +/- 1 and Injury Severity Score of 17 +/- 1 were evaluated. Fifty-six percent were men and falls were the most common mechanism (62%). An unfavorable outcome was seen in 56% of the study population with a mortality rate of 25%. ATIs were seen in 57% of the population and 22% had SCI. Patients with SCI had a significantly higher mortality compared with patients without SCI (38% vs. 22%, p = 0.032). However, there was no difference in unfavorable outcomes. Patients with ICSF had no differences in unfavorable outcomes compared with patients with SCI or ATI. Long-term survival analysis after discharge (mean = 2.8 years) demonstrated that patients with a favorable outcome had a significantly improved survival compared with patients with unfavorable outcomes (p < 0.001). CONCLUSION ICSFs were associated with an unfavorable outcome in the elderly population regardless of ATI or SCI. These unfavorable outcomes were also associated with long-term mortality. Strategies to reduce morbidity and mortality in this devastating injury will be essential to improve outcomes and maximize resource utilization.

Abstract
OBJECTIVES To assess the prevalence of carbohydrate and lipid disorders in adults with chronic spinal cord injury and evaluate their risk contribution to cardiovascular diseases and the potential impact of exercise and pharmacologic and dietary therapies to alter these disorders and reduce cardiovascular disease risk. DATA SOURCES MEDLINE (PubMed), Cochrane Database and Web sites of the American Spinal Injury Association, American Paraplegia Society, Paralyzed Veterans of America, Consortium of Spinal Cord Medicine, and WorldCat through August 2007. REVIEW METHODS English language observational studies addressing prevalence of carbohydrate and lipid disorders were included if they evaluated at least 100 adults with chronic spinal cord injury or a total of 100 subjects if using a control group. Epidemiologic investigations of more than 50 adults with spinal cord injury that were published in English after 1990 and reported cardiovascular morbidity and mortality were abstracted. Intervention studies from 1996-2007 were included regardless of design or size if they assessed exercise, diet, or pharmacologic therapies and reported carbohydrate, lipid, or cardiovascular outcomes. RESULTS The quality of evidence regarding the prevalence, impact, and outcomes of carbohydrate and lipid disorders in adults with chronic spinal cord injuries is weak. Evidence is limited by relatively few studies, small sample size, lack of appropriate control groups, failure to adjust for known confounding variables, and variation in reported outcomes. However, the existing evidence does not indicate that adults with spinal cord injuries are at markedly greater risk for carbohydrate and lipid disorders or subsequent cardiovascular morbidity and mortality than able-bodied adults. Body mass index is not reliable for assessing body composition, especially percent body fat, in adults with spinal cord injury. There are no high quality studies evaluating the impact of exercise, diet, or pharmacologic therapies on these disorders. CONCLUSIONS The available evidence does not support incorporating SCI status as an independent variable to assess risk of cardiovascular morbidity and mortality or to alter diagnostic/treatment thresholds compared to able-bodied adults. Furthermore, individuals with SCI may have unique physiologic differences compared to able-bodied individuals. As a result, it is uncertain that findings from studies conducted in able-bodied adults evaluating efficacy and harms of interventions to improve carbohydrate, lipid disorders, and subsequent CVD can be extrapolated to individuals with SCI. The role of exercise in individuals with spinal cord injuries represents a unique challenge and requires further exploration into the benefits, harms, and resource implications of broad-based spinal cord injury exercise programs.

Abstract
OBJECT The authors undertook this study to evaluate the incidence of spinal cord injury (SCI) in geriatric patients (> or = 70 years of age) and examine the impact of patient age, extent of neurological injury, and spinal level of injury on the mortality rate associated with traumatic SCI. METHODS A prospectively maintained SCI database (3481 patients) at a single institution was retrospectively studied for the period from 1978 through 2005. Parameters analyzed included patient age, admission American Spinal Injury Association (ASIA) motor score, level of SCI, mechanism of injury, and mortality data. The data pertaining to the 412 patients 70 years of age and older were compared with those pertaining to the younger cohort using a chi-square analysis. RESULTS Since 1980, the number of SCI-related hospital admissions per year have increased fivefold in geriatric patients and the percentage of geriatric patients within the SCI population has increased from 4.2 to 15.4%. In comparison with younger patients, geriatric patients were found to be less likely to have severe neurological deficits (greater percentage of ASIA Grades C and D injuries), but the mortality rates were higher in the older age group both for the period of hospitalization (27.7% compared with 3.2%, p < 0.001) and during 1-year follow-up. The mortality rates in this older population directly correlate with the severity of neurological injury (1-year mortality rate, ASIA Grade A 66%, Grade D 23%, p < 0.001). The mortality rate in elderly patients with SCI has not changed significantly over the last two decades, and the 1-year mortality rate was greater than 40% in all periods analyzed. CONCLUSIONS Spinal cord injuries in older patients are becoming more prevalent. The mortality rate in this patient group is much greater than in younger patients and should be taken into account when aggressive interventions are considered and in counseling families regarding prognosis.

Abstract
STUDY DESIGN Retrospective database review of all traumatic cervical spine injuries at a single tertiary care center. OBJECTIVE To determine the acute survival of patients aged 65 and over with a variety of cervical spine injuries, regardless of operative or conservative treatment. SUMMARY OF BACKGROUND DATA Elderly patients with cervical spine injuries have historically suffered from high mortality rates. More recent literature has demonstrated improved outcomes among operatively treated elderly, but has suggested that the nonoperative treatment of cervical injuries in this population may itself contribute to increased mortality rates. METHODS One thousand seventy-three consecutive patients were identified and initial hospitalization records reviewed. Ninety-four patients were excluded for incomplete data. The remaining 979 patients were divided by age into young and elderly groups. Sex distribution, mechanism, injury type, comorbidities, and mortality and complication rates were compared. Elderly patients were further divided into operative and nonoperative groups and acute outcomes were compared. RESULTS The overall acute mortality rate for all patients with cervical spine injuries was 5.92%. Eighty-six percent of all patients 65 and over survived, as did 96.1% of younger patients. Seventy-three percent of elderly patients with complete injuries survived, as did 80% of those with incomplete injuries, and 95.6% of intact elderly. Acute mortality rates were statistically comparable in both the operatively and nonoperatively treated groups of elderly. CONCLUSIONS In this large comprehensive series of elderly patients with cervical spine injuries, statistically comparable survival rates were achieved in both operatively treated and nonoperatively treated patient populations. This finding challenges the conclusion that the nonoperative treatment of the elderly necessarily results in increased acute mortality.

Abstract
OBJECTIVE To investigate the distribution of time of early death in the patients with cervical spinal cord injury (CSCI). METHODS The clinical data of 63 CECI patients, including demographics, mechanism of injury, cervical spinal cord injury level and severity, associated injury, radiographs, management, and the causes of death, the time from injury to hospitalization and the time from injury to death were retrospectively analyzed so as to detect the time and cause of early death. RESULTS The 63 CDCI patients died in early stage. 27 of the 63 patients (42.8%) died within a week after CSCI; 43 patients (68.3%) died within two weeks after CSCI, 57 patients (90.5%) died within four weeks after CSCI, and 6 patients (9.5%) died after four weeks after CSCI. CONCLUSION The peak time of death is a week after CSCI. The major time of death is two weeks after CSCI. 90.5% cases died within four weeks. Respiratory failure is the leading cause of early death in patients with CSCI.
