Abstract
Traumatic brain injury (TBI) is a global public health problem and a leading cause of mortality, morbidity, and disability. The increasing incidence combined with the heterogeneity and complexity of TBI will inevitably place a substantial burden on health systems. These findings emphasize the importance of obtaining accurate and timely insights into healthcare consumption and costs on a multi-national scale. This study aimed to describe intramural healthcare consumption and costs across the full spectrum of TBI in Europe. The Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury (CENTER-TBI) core study is a prospective observational study conducted in 18 countries across Europe and in Israel. The baseline Glasgow Coma Scale (GCS) was used to differentiate patients by brain injury severity in mild (GCS 13-15), moderate (GCS 9-12), or severe (GCS ≤8) TBI. We analyzed seven main cost categories: pre-hospital care, hospital admission, surgical interventions, imaging, laboratory, blood products, and rehabilitation. Costs were estimated based on Dutch reference prices and converted to country-specific unit prices using gross domestic product (GDP)-purchasing power parity (PPP) adjustment. Mixed linear regression was used to identify between-country differences in length of stay (LOS), as a parameter of healthcare consumption. Mixed generalized linear models with gamma distribution and log link function quantified associations of patient characteristics with higher total costs. We included 4349 patients, of whom 2854 (66%) had mild, 371 (9%) had moderate, and 962 (22%) had severe TBI. Hospitalization accounted for the largest part of the intramural consumption and costs (60%). In the total study population, the mean LOS was 5.1 days at the intensive care unit (ICU) and 6.3 days at the ward. For mild, moderate, and severe TBI, mean LOS was, respectively, 1.8, 8.9, and 13.5 days at the ICU and 4.5, 10.1, and 10.3 days at the ward. Other large contributors to the total costs were rehabilitation (19%) and intracranial surgeries (8%). Total costs increased with higher age and greater trauma severity (mild; €3,800 [IQR €1,400-14,000], moderate; €37,800 [IQR €14,900-€74,200], severe; €60,400 [IQR €24,400-€112,700]). The adjusted analysis showed that female patients had lower costs than male patients (odds ratio (OR) 0.80 [CI 0.75-1.85]). Increasing TBI severity was associated with higher costs, OR 1.46 (confidence interval [CI] 1.31-1.63) and OR 1.67 [CI 1.52-1.84] for moderate and severe patients, respectively. A worse pre-morbid overall health state, increasing age and more severe systemic trauma, expressed in the Injury Severity Score (ISS), were also significantly associated with higher costs. Intramural costs of TBI are significant and are profoundly driven by hospitalization. Costs increased with trauma severity and age, and male patients incurred higher costs. Reducing LOS could be targeted with advanced care planning, in order to provide cost-effective care.

Abstract
(1) Background: The SARS-CoV-2 pandemic had a significant impact on the management of traumatic brain injury (TBI). We aimed to compare the clinical characteristics and outcomes of TBI patients before and during the SARS-CoV-2 pandemic.; (2) Methods: We analyzed depicted data from existing medical records on sex, age, mechanism of injury, clinical performance at admission and discharge, neuroimaging, laboratory values at admission, mortality, duration of hospitalization, and referrals after discharge from the traumatology department for all adult patients during the SARS-CoV-2 pandemic and a year before. Variables were compared using the Chi-square or t-test between both groups.; (3) Results: Most patients had mild (n = 477), followed by moderate (11) and severe (11) TBI. Mild TBI was less frequent during the SARS-CoV-2 period (n = 174 vs. n = 303). The incidence of high falls increased during the SARS-CoV-2 period (14.5% vs. 24.7%; p < 0.05) in the group with mild TBI. Patients had similar mean Glasgow Coma Scales (GCS), Glasgow Outcome Scales-Extended (GOSE), and glucose levels at admission before and during the pandemic. Serum ethanol levels were significantly lower during the SARS-CoV-2 period (1.3 ± 0.7 mmol/L vs. 0.7 ± 1.2 mmol/L; p < 0.001). At discharge, the mean GCS was significantly lower (14.7 ± 1.8 vs. 14.1 ± 0.5; p < 0.05) for patients treated during the SARS-CoV-2 period than before the SARS-CoV-2 period. There were no differences in GOSE; (4) Conclusions: our results demonstrated a significant impact of SARS-CoV-2 pandemic on the frequency, mechanism, and consequences of TBI, and may help improve care for our patients.

Abstract
This study evaluates the applicability of S100B levels, mean maximum velocity (Vmean) over time, pulsatility index (PI), intracranial pressure (ICP), and body temperature (T) for the prediction of the treatment of patients with traumatic brain injury (TBI). Sixty patients defined by the Glasgow Coma Scale score ≤ 8 were stratified using the Glasgow Coma Scale into 2 groups: favorable (FG: Glasgow Outcome Scale ≥ 4) and unfavorable (UG: Glasgow Outcome Scale < 4). The S100B concentration was at the time of hospital admission. Vmean was measured using transcranial Doppler. PI was derived from a transcranial Doppler examination. T was measured in the temporal artery. The differences in mean between FG and UG were tested using a bootstrap test of 10,000 repetitions with replacement. Changes in S100B, Vmean, PI, ICP, and T levels stratified by the group were calculated using the one-way aligned rank transform for nonparametric factorial analysis of variance. The reference ranges for the levels of S100B, Vmean, and PI were 0.05 to 0.23 µg/L, 30.8 to 73.17 cm/s, and 0.62 to 1.13, respectively. Both groups were defined by an increase in Vmean, a decrease in S100B, PI, and ICP levels; and a virtually constant T. The unfavorable outcome is defined by significantly higher levels of all parameters, except T. A favorable outcome is defined by S100B < 3 mg/L, PI < 2.86, ICP > 25 mm Hg, and Vmean > 40 cm/s. The relationships provided may serve as indicators of the results of the TBI treatment.

Abstract
The distinguishing pathogenic features of neurodegenerative diseases include mitochondrial dysfunction and derived reactive oxygen species generation. The neural tissue is highly sensitive to oxidative stress and this is a prominent factor in both chronic and acute neurodegeneration. Based on this, therapeutic strategies using antioxidant molecules towards redox equilibrium have been widely used for the treatment of several brain pathologies. Globally, polyphenols, carotenes and vitamins are among the most typical exogenous antioxidant agents that have been tested in neurodegeneration as adjunctive therapies. However, other types of antioxidants, including hormones, such as the widely used melatonin, are also considered neuroprotective agents and have been used in different neurodegenerative contexts. This review highlights the most relevant mitochondrial antioxidant targets in the main neurodegenerative disorders including Alzheimer’s disease, Parkinson’s disease, and Huntington’s disease and also in the less represented amyotrophic lateral sclerosis, as well as traumatic brain injury, while summarizing the latest randomized placebo-controlled trials.

Characterisation of Severe Traumatic Brain Injury Severity from Fresh Cerebral Biopsy of Living Patients: An Immunohistochemical Study. Biomedicines 2022; 10:biomedicines10030518.

Abstract
Traumatic brain injury (TBI) is an extremely complex disease and current systems classifying TBI as mild, moderate, and severe often fail to capture this complexity. Neuroimaging cannot resolve the cellular and molecular changes due to lack of resolution, and post-mortem tissue examination may not adequately represent acute disease. Therefore, we examined the cellular and molecular sequelae of TBI in fresh brain samples and related these to clinical outcomes. Brain biopsies, obtained shortly after injury from 25 living adult patients suffering severe TBI, underwent immunohistochemical analysis. There were no adverse events. Immunostaining revealed various qualitative cellular and biomolecular changes relating to neuronal injury, dendritic injury, neurovascular injury, and neuroinflammation, which we classified into 4 subgroups for each injury type using the newly devised Yip, Hasan and Uff (YHU) grading system. Based on the Glasgow Outcome Scale-Extended, a total YHU grade of ≤8 or ≥11 had a favourable and unfavourable outcome, respectively. Biomolecular changes observed in fresh brain samples enabled classification of this heterogeneous patient population into various injury severity categories based on the cellular and molecular pathophysiology according to the YHU grading system, which correlated with outcome. This is the first study investigating the acute biomolecular response to TBI.

Abstract
The high frequency of traumatic brain injury imposes severe economic stress on health and insurance services. The objective of this study was to analyze the association between the serum S100B protein, the Gosling pulsatility index (PI), and the level of oxygen saturation at the tip of the internal jugular vein (SjVO2%) in patients diagnosed with severe TBI. The severity of TBI was assessed by a GCS score ≤ 8 stratified by Glasgow outcome scale (GOS) measured on the day of discharge from the hospital. Two groups were included: GOS < 4 (unfavorable group (UG)) and GOS ≥ 4 (favorable group (UG)). S100B levels were higher in the UG than in the FG. PI levels in the UG were also substantially higher than in the FG. There were similar levels of SjVO2 in the two groups. This study confirmed that serum S100B levels were higher in patients with unfavorable outcomes than in those with favorable outcomes. Moreover, a clear demarcation in PI between unfavorable and FGs was observed. This report shows that mortality and morbidity rates in patients with traumatic brain injury can be assessed within the first 4 days of hospitalization using the S100B protein, PI values, and SjVO2.

Abstract
Purpose: A former rodent study showed that cerebral traumatic microbleeds (TMBs) may temporarily become invisible shortly after injury when detected by susceptibility weighted imaging (SWI). The present study aims to validate this phenomenon in human SWI. Methods: In this retrospective study, 46 traumatic brain injury (TBI) patients in various forms of severity were included and willingly complied with our strict selection criteria. Clinical parameters potentially affecting TMB count, Rotterdam and Marshall CT score, Mayo Clinic Classification, contusion number, and total volume were registered. The precise time between trauma and MRI [5 h 19 min to 141 h 54 min, including SWI and fluid-attenuated inversion recovery (FLAIR)] was individually recorded; TMB and FLAIR lesion counts were assessed. Four groups were created based on elapsed time between the trauma and MRI: 0–24, 24–48, 48–72, and >72 h. Kruskal–Wallis, ANOVA, Chi-square, and Fisher’s exact tests were used to reveal differences among the groups within clinical and imaging parameters; statistical power was calculated retrospectively for each comparison. Results: The Kruskal–Wallis ANOVA with Conover post hoc analysis showed significant (p = 0.01; 1−β > 0.9) median TMB number differences in the subacute period: 0–24 h = 4.00 (n = 11); 24–48 h = 1 (n = 14); 48–72 h = 1 (n = 11); and 72 h ≤ 7.5 (n = 10). Neither clinical parameters nor FLAIR lesions depicted significant differences among the groups. Conclusion: Our results demonstrate that TMBs on SWI MRI may temporarily become less detectable at 24–72 h following TBI.

The pivotal role of micro-environmental cells in a human blood-brain barrier in vitro model of cerebral ischemia: functional and transcriptomic analysis. Fluids Barriers CNS 2020; 17:19.

Abstract
Background The blood–brain barrier (BBB) is altered in several diseases of the central nervous system. For example, the breakdown of the BBB during cerebral ischemia in stroke or traumatic brain injury is a hallmark of the diseases’ progression. This functional damage is one key event which is attempted to be mimicked in in vitro models. Recent studies showed the pivotal role of micro-environmental cells such as astrocytes for this barrier damage in mouse stroke in vitro models. The aim of this study was to evaluate the role of micro-environmental cells for the functional, paracellular breakdown in a human BBB cerebral ischemia in vitro model accompanied by a transcriptional analysis. Methods Transwell models with human brain endothelial cell line hCMEC/D3 in mono-culture or co-culture with human primary astrocytes and pericytes or rat glioma cell line C6 were subjected to oxygen/glucose deprivation (OGD). Changes of transendothelial electrical resistance (TEER) and FITC-dextran 4000 permeability were recorded as measures for paracellular tightness. In addition, qPCR and high-throughput qPCR Barrier chips were applied to investigate the changes of the mRNA expression of 38 relevant, expressed barrier targets (tight junctions, ABC-transporters) by different treatments. Results In contrast to the mono-culture, the co-cultivation with human primary astrocytes/pericytes or glioma C6 cells resulted in a significantly increased paracellular permeability after 5 h OGD. This indicated the pivotal role of micro-environmental cells for BBB breakdown in the human model. Hierarchical cluster analysis of qPCR data revealed differently, but also commonly regulated clustered targets dependent on medium exchange, serum reduction, hydrocortisone addition and co-cultivations. Conclusions The co-cultivation with micro-environmental cells is necessary to achieve a functional breakdown of the BBB in the cerebral ischemia model within an in vivo relevant time window. Comprehensive studies by qPCR revealed that distinct expression clusters of barrier markers exist and that these are regulated by different treatments (even by growth medium change) indicating that controls for single cell culture manipulation steps are crucial to understand the observed effects properly.

Abstract
Background: Neuro-surgical emergencies are serious (long-term disability and high mortality) and costly to the national health services. Tele-medicine intervention can facilitate to reduce this gap. Our study aims to evaluate the cost-effectiveness of tele-video-consultation intervention for the management of neuro-surgical emergencies in the general hospitals. Methods: We retrieved health service data from the tele-consultation service, online tele-medicine database portal and hospital patient registry, between January 2009 and December 2012 and evaluated cost-effectiveness of the tele-video-consultation intervention from an Italian National Health Service perspective. Results: Seventy-five percent of the tele-consultations were completed within 15 min and 90% within 30 min. The average costs were €2,326 in the intervention group and €4,173 in the care as usual group. The intervention avoided 73% potential transfer (saving of 139,916 km travel distance during a 4-years period). The incremental cost-saving per transfer avoided from the tele-medicine intervention was €365. Conclusions: Tele-medicine intervention could be worth investing from the Italian National Health Service perspective.

Abstract
BACKGROUND Traumatic brain injury (TBI), particularly in the elderly patient population, is known to be the single largest cause of death and disability worldwide. The purpose of this retrospective study was to evaluate clinical factors predicting poor outcome with special emphasis on the impact of respiratory failure (RF) on mortality in elderly patients with isolated severe TBI. METHODS All elderly patients (age ≥ 65 years) with isolated severe head injury, admitted to this level I trauma center, during a period of 18 years (from January 1992 to December 2010) were identified from the trauma registry. The medical records were reviewed for demographics, mechanism of injury (MOI), GCS score at admission, RF, pupillary light reflex (LR), CT findings (subdural hematoma, subarachnoid hematoma, edema, midline-shift), and whether there was conservative treatment or surgical intervention and the Glasgow Outcome Score (GOS) at hospital discharge. Stepwise logistic regression analysis was used to identify risk factors for a poor prognosis and outcome. RESULTS The following variables influenced the mortality: respiratory failure, pupillary response, and the injury severity score (ISS). A significant increased risk of death was also found for patients with a midline shift of over 15 mm. CONCLUSIONS The present study predicts a strong correlation between respiratory failure, pathological pupillary response, a higher ISS, and substantial midline shift with poor outcomes in elderly patients sustaining an isolated severe TBI.

Abstract
Health disparities based on race and socioeconomic status are a serious problem in the US health care system, but disparities in outcomes related to traumatic injury have received relatively little attention in the research literature.This study uses data from the State Inpatient Database for Michigan including all trauma-related hospital admissions in the period from 2006 to 2014 in the Detroit metropolitan area (N = 407,553) to examine the relationship between race (White N = 232,109; African American N = 86,356, Hispanic N = 2709, Other N = 10,623), socioeconomic background, and in-hospital trauma mortality.Compared with other groups, there was a higher risk of mortality after trauma among African Americans (odds ratio [OR] = 1.20, P < .001), people living in high-poverty neighborhoods (OR = 1.01, P < .001), and those enrolled in public health insurance programs (OR = 1.53, P < .001). African American patients were more likely to have had traumatic injuries caused by certain mechanisms with higher risk of death (P < .001). After controlling for mechanism alone in multiple logistic regression, African American race remained a significant predictor of mortality risk (OR = 1.12, P < .001). After additionally controlling for the socioeconomic factors of insurance status and neighborhood poverty levels, there were no longer any significant differences between racial groups in terms of mortality (OR = 0.99, P = .746).These results suggest that in this population the racial inequalities in mortality outcomes were fully mediated by differences between groups in the pattern of injuries suffered and differences in risk based on socioeconomic factors.

Abstract
The blood-brain barrier (BBB) is damaged during ischemic insults such as traumatic brain injury or stroke. This contributes to vasogenic edema formation and deteriorate disease outcomes. Enormous efforts are pursued to understand underlying mechanisms of ischemic insults and develop novel therapeutic strategies. In the present study the effects of PPARα agonist WY-14643 were investigated to prevent BBB breakdown and reduce edema formation. WY-14643 inhibited barrier damage in a mouse BBB in vitro model of traumatic brain injury based on oxygen/glucose deprivation in a concentration dependent manner. This was linked to changes of the localization of tight junction proteins. Furthermore, WY-14643 altered phosphorylation of kinases ERK1/2, p38, and SAPK/JNK and was able to inhibit proteosomal activity. Moreover, addition of WY-14643 upregulated PAI-1 leading to decreased t-PA activity. Mouse in vivo experiments showed significantly decreased edema formation in a controlled cortical impact model of traumatic brain injury after WY-14643 application, which was not found in PAI-1 knockout mice. Generally, data suggested that WY-14643 induced cellular responses which were dependent as well as independent from PPARα mediated transcription. In conclusion, novel mechanisms of a PPARα agonist were elucidated to attenuate BBB breakdown during traumatic brain injury in vitro.

Abstract
OBJECTIVES This is the first socioeconomic study on traumatic brain injury (TBI) undertaken to determine the sociodemographic factors implicated in the occurrence of TBI and to assess the value of the direct cost of the management of TBI at the initial phase in the Hubert Koutoukou Maga National Teaching Hospital of Cotonou. METHODS This was a prospective study with descriptive and analytic aim that took place from January 1 to July 31, 2014. An individual approach of each patient's expenditure was undertaken via the use of a questionnaire on which all expenses were identified systematically. The dependent variable was the global direct cost of care. The independent variables were the type of accident, severity of the TBI, the structures of care, the stay in the resuscitation unit, the duration of hospitalization. RESULTS There were 297 patients with TBI: 258 men (86.9%) and 39 women (13.1%), with a sex ratio of 6.61. The average age of patients was 34.3 ± 12.39 years. The average direct cost of care for TBI was €285.67 ± 310.15. The average cost for severe TBI was €522.08 ± 439.91 versus €188.19 ± 164.83 for mild TBI (odds ratio 5.52; standard deviation: 0.0527-0.6222). The average cost was increased significantly more when the patients went through a peripheral hospital (odds ratio 3.65; standard deviation: 1.819-7.3245). CONCLUSIONS The organization of Benin's health system did not allow for the optimum management of TBI. It seems imperative to develop an insurance system that will allow a proper and effective support for victims of traffic accidents.

Abstract
Chronic traumatic encephalopathy (CTE) is a neurodegenerative condition associated with repetitive mild traumatic brain injury. In recent years, attention has focused on emerging evidence linking the development of CTE to concussive injuries in athletes and military personnel; however, the underlying molecular pathobiology of CTE remains unclear. Here, we provide evidence that the blood-brain barrier (BBB) is disrupted in regions of dense perivascular p-Tau accumulation in a case of CTE. Immunoreactivity patterns of the BBB-associated tight junction components claudin-5 and zonula occludens-1 were markedly discontinuous or absent in regions of perivascular p-Tau deposition; there was also immunohistochemical evidence of a BBB in these foci. Because the patient was diagnosed premortem clinically as having progressive supranuclear palsy (PSP), we also compromised that the CTE alterations appear to be distinct from those in the brain of a patient with PSP. This report represents the first description of BBB dysfunction in a pathologically proven CTE case and suggests a vascular component in the postconcussion cascade of events that may ultimately lead to development of a progressive degenerative disorder. BBB dysfunction may represent a correlate of neural dysfunction in live subjects suspected of being at risk for development of CTE.

Abstract
OBJECTIVE The first aim of this study was to estimate the prevalence of TBI and epilepsy in a French prison population and to study variables known to be associated with TBI. The second aim was to compare prisoners with and without a history of TBI. PARTICIPANTS All offenders (females, males and juveniles) admitted consecutively to Fleury-Mérogis prison over a period of 3 months were included in the study. DESIGN During the admission procedure, offenders were interviewed by healthcare staff using a self-reported questionnaire. RESULTS In all, 1221 prisoners were included. The rates of TBI and epilepsy were high, with a prevalence of 30.6% and 5.9%, respectively. Psychiatric care, anxiolytic and antidepressant treatment, use of alcohol and cannabis were all significantly higher among offenders with a history of TBI. Moreover, the number of times in custody and the total time spent in jail over the preceding 5 years were significantly higher among offenders with a history of TBI. CONCLUSIONS These results provide further evidence that specific measures need to be developed such as, first of all, screening for TBI upon arrival in prison.

Abstract
The main cause of death and serious disability in bicycle accidents is traumatic brain injury (TBI). The aim of this population-based study was to assess the incidence and costs of bicycle-related TBI across various age groups, and in comparison to all bicycle-related injuries, to identify main risk groups for the development of preventive strategies. Data from the National Injury Surveillance System and National Medical Registration were used for all patients with bicycle-related injuries and TBI who visited a Dutch emergency department (ED) between 1998 and 2012. Demographics and national, weighted estimates of injury mechanism, injury severity and costs were analysed per age group. Direct healthcare costs and indirect costs were determined using the incidence-based Dutch Burden of Injury Model. Between 1998 and 2012, the incidence of ED treatments due to bicycle-related TBI strongly increased with 54%, to 43 per 100,000 persons in 2012. However, the incidence of all bicycle-related injuries remained stable, from 444 in 1998 to 456/100,000 in 2012. Incidence of hospital admission increased in both TBI (92%) and all injuries from cycling (71%). Highest increase in incidence of both ED treatments and hospital admissions was seen in adults aged 55+. The injury rate of TBI per kilometre travelled increased (44%) except in children, but decreased (-4%) for all injuries, showing a strong decrease in children (-36%) but an increase in men aged 25+, and women aged 15+. Total costs of bicycle-related TBI were €74.5 million annually. Although bicycle-related TBI accounted for 9% of the incidence of all ED treatments due to cycling, it accounted for 18% of the total costs due to all bicycle-related injuries (€410.7 million). Children and adolescents (aged 0-24) had highest incidence of ED treatments due to bicycle-related injuries. Men in the working population (aged 15-64) had highest indirect costs following injuries from cycling, including TBI. Older cyclists (aged 55+) were identified as main risk group for TBI, as they had highest ED attendance, injury rate, injury severity, admission to hospital or intensive care unit, and costs. Incidence of ED treatments due to cycling are high and often involve TBI, imposing a high burden on individuals and society. Older cyclists aged 55+ were identified as main risk group for TBI to be targeted in preventive strategies, due to their high risk for (serious) injuries and ever-increasing share of ED visits and hospital admissions.

Abstract
Traumatic brain injury (TBI) is a leading cause of death, and in a recent analysis it was found that nearly one-third of all injury-related deaths in the US have at least one diagnosis of TBI (CDC-Quickstats, 2010). This chapter presents the burden of TBI as regards age group, gender, costs, race, emergency department (ED) visits, hospitalizations, and deaths. Injury trends over a 15 year period are examined. Rehabilitation estimates and disability estimates are also available. Through good epidemiology we can better understand the causes of TBI and design more effective intervention programs to reduce injury. Important sources of evidence for this chapter include mostly studies from the US because of their leading work in the epidemiology of this important injury.

Abstract
Traumatic brain injury (TBI) is one of the most frequent causes of death in the young population. Several clinical trials have unsuccessfully focused on direct neuroprotective therapies. Recently immunotherapeutic strategies shifted into focus of translational research in acute CNS diseases. Cross-talk between activated microglia and blood-brain barrier (BBB) could initiate opening of the BBB and subsequent recruitment of systemic immune cells and mediators into the brain. Stabilization of the BBB after TBI could be a promising strategy to limit neuronal inflammation, secondary brain damage and acute neurodegeneration. This review provides an overview on the pathophysiology of TBI and brain edema formation including definitions and classification of TBI, current clinical treatment strategies, as well as current understanding on the underlying cellular processes. A summary of in vivo and in vitro models to study different aspects of TBI is presented. Three mechanisms proposed for stabilization of the BBB, myosin light chain kinases, glucocorticoid receptors and peroxisome proliferator-activated receptors are reviewed for their influence on barrier-integrity and outcome after TBI. In conclusion, the BBB is recommended as a promising target for the treatment of traumatic brain injury, and it is suggested that a combination of BBB stabilization and neuroprotectants may improve therapeutic success.

Abstract
OBJECTIVE Traumatic brain injury (TBI) is a major cause of death and disability, leading to great personal suffering and huge costs to society. Integrated knowledge on epidemiology, economic consequences and disease burden of TBI is scarce but essential for optimizing healthcare policy and preventing TBI. This study aimed to estimate incidence, cost-of-illness and disability-adjusted life years (DALYs) of TBI in the Netherlands. METHODS This study included data on all TBI patients who were treated at an Emergency Department (ED - National Injury Surveillance System), hospitalized (National Medical Registration), or died due to their injuries in the Netherlands between 2010-2012. Direct healthcare costs and indirect costs were determined using the incidence-based Dutch Burden of Injury Model. Disease burden was assessed by calculating years of life lost (YLL) owing to premature death, years lived with disability (YLD) and DALYs. Incidence, costs and disease burden were stratified by age and gender. RESULTS TBI incidence was 213.6 per 100,000 person years. Total costs were €314.6 (USD $433.8) million per year and disease burden resulted in 171,200 DALYs (on average 7.1 DALYs per case). Men had highest mean costs per case (€19,540 versus €14,940), driven by indirect costs. 0-24-year-olds had high incidence and disease burden but low economic costs, whereas 25-64-year-olds had relatively low incidence but high economic costs. Patients aged 65+ had highest incidence, leading to considerable direct healthcare costs. 0-24-year-olds, men aged 25-64 years, traffic injury victims (especially bicyclists) and home and leisure injury victims (especially 0-5-year-old and elderly fallers) are identified as risk groups in TBI. CONCLUSIONS The economic and health consequences of TBI are substantial. The integrated approach of assessing incidence, costs and disease burden enables detection of important risk groups in TBI, development of prevention programs that target these risk groups and assessment of the benefits of these programs.

Abstract
The effort to standardize the methodology and adherence to recommended principles for all economic evaluations has been emphasized in medical literature. The objective of this review is to examine whether economic evaluations in traumatic brain injury (TBI) research have been compliant with existing guidelines. Medline search was performed between January 1, 1995 and August 11, 2012. All original TBI-related full economic evaluations were included in the study. Two authors independently rated each study's methodology and data presentation to determine compliance to the 10 methodological principles recommended by Blackmore et al. Descriptive analysis was used to summarize the data. Inter-rater reliability was assessed with Kappa statistics. A total of 28 studies met the inclusion criteria. Eighteen of these studies described cost-effectiveness, seven cost-benefit, and three cost-utility analyses. The results showed a rapid growth in the number of published articles on the economic impact of TBI since 2000 and an improvement in their methodological quality. However, overall compliance with recommended methodological principles of TBI-related economic evaluation has been deficient. On average, about six of the 10 criteria were followed in these publications, and only two articles met all 10 criteria. These findings call for an increased awareness of the methodological standards that should be followed by investigators both in performance of economic evaluation and in reviews of evaluation reports prior to publication. The results also suggest that all economic evaluations should be made by following the guidelines within a conceptual framework, in order to facilitate evidence-based practices in the field of TBI.

Characteristics of acute treatment costs of traumatic brain injury in Eastern China--a multi-centre prospective observational study. Injury 2012; 43:2094-9. [PMID: 22595490 DOI: 10.1016/j.injury.2012.03.028] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2011] [Revised: 03/10/2012] [Accepted: 03/28/2012] [Indexed: 02/02/2023]
Abstract
INTRODUCTION This study investigated acute treatment costs and related factors for traumatic brain injuries (TBI) in eastern China based on a prospective multicentre study. MATERIALS AND METHODS Data were prospectively collected from 80 hospitals in eastern China by standardized structured questionnaires during 2004. Included patients were admitted to hospitals via an emergency service with a diagnosis of TBI. The total acute hospitalization treatment costs derived from unsubsidized total hospital billings were used as the main outcome measure. Univariate and multivariable regression models were used to examine factors associated with each outcome. RESULTS In total, 13,007 TBI cases were identified from 80 hospitals in eastern China. The median cost per hospitalization was $879 US (range, $72-45,894). The median cost per day was $79 (interquartile range, $49-126). The hospitalization costs varied based on the cause of TBI, with a median of $1017 for traffic accidents, $816 for falls, $490 for blows to the head, and $712 for falls. The hospitalization costs also varied by injury type with a mean of $918 for TBI associated with other injuries and $831 for isolated TBI. Using multiple regression analyses, lower admission Glasgow Coma score, longer hospital stay (LOS), male sex, transient patient status, traffic accident, injury occurring on a construction site, treatment at a tertiary hospital, neurosurgical intensive care unit (NICU) or ICU stay, associated polytrauma, and those who needed a neurosurgical operation had significantly higher total acute hospitalization costs than those of other groups. Good recovery and self-paying patients had lower total costs. A double LOS was associated with a 1.61 (95% confidence interval, 1.59-1.62) times higher hospital cost. CONCLUSION Our results have potential implications for health-care resource planning during TBI treatment. Measures to prevent traffic accidents and reduce the LOS may help to reduce acute hospitalization costs.

Abstract
Data on traumatic brain injury (TBI) economic outcomes are limited. We used Rochester Epidemiology Project (REP) resources to estimate long-term medical costs for clinically-confirmed incident TBI across the full range of severity after controlling for pre-existing conditions and co-occurring injuries. All Olmsted County, Minnesota, residents with diagnoses indicative of potential TBI from 1985-2000 (n=46,114) were identified, and a random sample (n=7175) was selected for medical record review to confirm case status, and to characterize as definite (moderate/severe), probable (mild), or possible (symptomatic) TBI. For each case, we identified one age- and sex-matched non-TBI control registered in REP in the same year (±1 year) as case's TBI. Cases with co-occurring non-head injuries were assessed for non-head-injury severity and assigned similar non-head-injury-severity controls. The 1145 case/control pairs for 1988-2000 were followed until earliest death/emigration of either member for medical costs 12 months before and up to 6 years after baseline (i.e., injury date for cases and comparable dates for controls). Differences between case and control costs were stratified by TBI severity, as defined by evidence of brain injury; comparisons used Wilcoxon signed-rank plus multivariate modeling (adjusted for pre-baseline characteristics). From baseline until 6 years, each TBI category exhibited significant incremental costs. For definite and probable TBI, most incremental costs occurred within the first 6 months; significant long-term incremental medical costs were not apparent among 1-year survivors. By contrast, cost differences between possible TBI cases and controls were not as great within the first 6 months, but were substantial among 1-year survivors. Although mean incremental costs were highest for definite cases, probable and possible cases accounted for>90% of all TBI events and 66% of total incremental costs. Preventing probable and possible events might facilitate substantial reductions in TBI-associated medical care costs.

Abstract
BACKGROUND The spectrum of disorders of the brain is large, covering hundreds of disorders that are listed in either the mental or neurological disorder chapters of the established international diagnostic classification systems. These disorders have a high prevalence as well as short- and long-term impairments and disabilities. Therefore they are an emotional, financial and social burden to the patients, their families and their social network. In a 2005 landmark study, we estimated for the first time the annual cost of 12 major groups of disorders of the brain in Europe and gave a conservative estimate of €386 billion for the year 2004. This estimate was limited in scope and conservative due to the lack of sufficiently comprehensive epidemiological and/or economic data on several important diagnostic groups. We are now in a position to substantially improve and revise the 2004 estimates. In the present report we cover 19 major groups of disorders, 7 more than previously, of an increased range of age groups and more cost items. We therefore present much improved cost estimates. Our revised estimates also now include the new EU member states, and hence a population of 514 million people. AIMS To estimate the number of persons with defined disorders of the brain in Europe in 2010, the total cost per person related to each disease in terms of direct and indirect costs, and an estimate of the total cost per disorder and country. METHODS The best available estimates of the prevalence and cost per person for 19 groups of disorders of the brain (covering well over 100 specific disorders) were identified via a systematic review of the published literature. Together with the twelve disorders included in 2004, the following range of mental and neurologic groups of disorders is covered: addictive disorders, affective disorders, anxiety disorders, brain tumor, childhood and adolescent disorders (developmental disorders), dementia, eating disorders, epilepsy, mental retardation, migraine, multiple sclerosis, neuromuscular disorders, Parkinson's disease, personality disorders, psychotic disorders, sleep disorders, somatoform disorders, stroke, and traumatic brain injury. Epidemiologic panels were charged to complete the literature review for each disorder in order to estimate the 12-month prevalence, and health economic panels were charged to estimate best cost-estimates. A cost model was developed to combine the epidemiologic and economic data and estimate the total cost of each disorder in each of 30 European countries (EU27+Iceland, Norway and Switzerland). The cost model was populated with national statistics from Eurostat to adjust all costs to 2010 values, converting all local currencies to Euro, imputing costs for countries where no data were available, and aggregating country estimates to purchasing power parity adjusted estimates for the total cost of disorders of the brain in Europe 2010. RESULTS The total cost of disorders of the brain was estimated at €798 billion in 2010. Direct costs constitute the majority of costs (37% direct healthcare costs and 23% direct non-medical costs) whereas the remaining 40% were indirect costs associated with patients' production losses. On average, the estimated cost per person with a disorder of the brain in Europe ranged between €285 for headache and €30,000 for neuromuscular disorders. The European per capita cost of disorders of the brain was €1550 on average but varied by country. The cost (in billion €PPP 2010) of the disorders of the brain included in this study was as follows: addiction: €65.7; anxiety disorders: €74.4; brain tumor: €5.2; child/adolescent disorders: €21.3; dementia: €105.2; eating disorders: €0.8; epilepsy: €13.8; headache: €43.5; mental retardation: €43.3; mood disorders: €113.4; multiple sclerosis: €14.6; neuromuscular disorders: €7.7; Parkinson's disease: €13.9; personality disorders: €27.3; psychotic disorders: €93.9; sleep disorders: €35.4; somatoform disorder: €21.2; stroke: €64.1; traumatic brain injury: €33.0. It should be noted that the revised estimate of those disorders included in the previous 2004 report constituted €477 billion, by and large confirming our previous study results after considering the inflation and population increase since 2004. Further, our results were consistent with administrative data on the health care expenditure in Europe, and comparable to previous studies on the cost of specific disorders in Europe. Our estimates were lower than comparable estimates from the US. DISCUSSION This study was based on the best currently available data in Europe and our model enabled extrapolation to countries where no data could be found. Still, the scarcity of data is an important source of uncertainty in our estimates and may imply over- or underestimations in some disorders and countries. Even though this review included many disorders, diagnoses, age groups and cost items that were omitted in 2004, there are still remaining disorders that could not be included due to limitations in the available data. We therefore consider our estimate of the total cost of the disorders of the brain in Europe to be conservative. In terms of the health economic burden outlined in this report, disorders of the brain likely constitute the number one economic challenge for European health care, now and in the future. Data presented in this report should be considered by all stakeholder groups, including policy makers, industry and patient advocacy groups, to reconsider the current science, research and public health agenda and define a coordinated plan of action of various levels to address the associated challenges. RECOMMENDATIONS Political action is required in light of the present high cost of disorders of the brain. Funding of brain research must be increased; care for patients with brain disorders as well as teaching at medical schools and other health related educations must be quantitatively and qualitatively improved, including psychological treatments. The current move of the pharmaceutical industry away from brain related indications must be halted and reversed. Continued research into the cost of the many disorders not included in the present study is warranted. It is essential that not only the EU but also the national governments forcefully support these initiatives.

Abstract
Post-traumatic epilepsy (PTE) accounts for 10-20% of symptomatic epilepsies. The urgency to understand the process of post-traumatic epileptogenesis and search for antiepileptogenic treatments is emphasized by a recent increase in traumatic brain injury (TBI) related to military combat or accidents in the aging population. Recent developments in modeling of PTE in rodents have provided tools for identification of novel drug targets for antiepileptogenesis and biomarkers for predicting the risk of epileptogenesis and treatment efficacy after TBI. Here we review the available data on endophenotypes of humans and rodents with TBI associated with epilepsy. Also, current understanding of the mechanisms and biomarkers for PTE as well as factors associated with preclinical study designs are discussed. Finally, we summarize the attempts to prevent PTE in experimental models.

Abstract
BACKGROUND Little is known about the cost of neurological disorders in Norway. OBJECTIVES To estimate the cost of disorders of the brain, including the main psychiatric, neurological and neurosurgical conditions in Norway. METHODS Most of the data are extrapolations from a large European cost study that collected the best available epidemiological and health economical evidence for the year 2004. Some epidemiological data are available from Norway, but very little on costs. RESULTS Brain disorders seemed to affect 1.5 million Norwegians in 2004, and the total cost amounted to 5.8 billion Euros. The most prevalent disorders are anxiety disorders and migraine, and the most costly are affective disorders, addiction and dementia. Migraine is the most costly of the purely neurological conditions, followed by stroke, epilepsy and Parkinson's disease. The indirect costs account for more than half of the total costs. DISCUSSION Although the different brain disorders are very dissimilar in appearance, from health economic and public health perspectives, it is relevant to view them as a whole, since many of them share important pathophysiological mechanisms. This means that new insights into one disorder can have relevance for many other disorders. CONCLUSION As a result of the high impact on individuals and society, more resources should be allocated to treatment and research into brain disorders.

Abstract
PURPOSE This review summarizes protein biomarkers in mild and severe traumatic brain injury in adults and children and presents a strategy for conducting rationally designed clinical studies on biomarkers in head trauma. METHODS We performed an electronic search of the National Library of Medicine's MEDLINE and Biomedical Library of University of Pennsylvania database in March 2008 using a search heading of traumatic head injury and protein biomarkers. The search was focused especially on protein degradation products (spectrin breakdown product, c-tau, amyloid-beta(1-42)) in the last 10 years, but recent data on "classical" markers (S-100B, neuron-specific enolase, etc.) were also examined. RESULTS We identified 85 articles focusing on clinical use of biomarkers; 58 articles were prospective cohort studies with injury and/or outcome assessment. CONCLUSIONS We conclude that only S-100B in severe traumatic brain injury has consistently demonstrated the ability to predict injury and outcome in adults. The number of studies with protein degradation products is insufficient especially in the pediatric care. Cohort studies with well-defined end points and further neuroproteomic search for biomarkers in mild injury should be triggered. After critically reviewing the study designs, we found that large homogenous patient populations, consistent injury, and outcome measures prospectively determined cutoff values, and a combined use of different predictors should be considered in future studies.

Abstract
OBJECTIVE To systematically review prospective cohort studies that investigated prognostic factors associated with long-term activity limitations or participation restrictions and productivity after a traumatic brain injury. DATA SOURCES PubMed and Psychinfo were searched from 1995 to April 2005, and references were checked. REVIEW METHODS Publications were selected if the study assessed prognostic factors for activity limitations or participation restrictions at least one year post injury; outcome was measured with another or additional measure besides the Glasgow Outcome Scale; the design was a prospective cohort study of adult traumatic brain injury patients; the article was a full-text article written in English, French, German or Dutch. Two reviewers independently assessed methodological quality. A study was considered as 'high quality' if it satisfied at least half of the maximum available quality score. RESULTS Thirty-five articles reporting on 14 cohorts were included. Due to heterogeneity in prognostic factors and outcome measures, a best-evidence synthesis was performed. All cohorts were of high quality. Strong evidence for predicting disability was found for older age, pre-injury unemployment, pre-injury substance abuse, and more disability at rehabilitation discharge. Strong prognostic factors for being non-productive were pre-injury unemployment, longer post-traumatic amnesia, more disability at rehabilitation admission, and pre-injury substance abuse. CONCLUSION Older age, pre-injury unemployment, pre-injury substance abuse and more disability at rehabilitation discharge are important predictors of long-term disability. Pre-injury unemployment, longer post-traumatic amnesia, more disability at rehabilitation admission and pre-injury substance abuse are important predictors of being non-productive.

Abstract
A comparison of outcomes between different modes of head-injury treatment in the elderly has important bearing on questions of cost-effectiveness and medical ethics. Here, we have examined rates of mortality in elderly head-trauma victims to determine whether it is valid to differentiate an "edge" age group of younger elderly patients, 65-74 years of age, from older elderly patients, considering possible benefit from intensive treatment and surgical intervention. We collected data from 1926 cases of head trauma and separated them into three age groups: 14-64 years, 65-74 years, and 75 years or older. We then compared these groups with respect to cause of injury, severity of injury, and whether or not treatment included either admission to an Intensive Care Unit (ICU) or surgical intervention. We found that road traffic accidents were the major cause of head injury in the younger age group, whereas in the elderly falls predominated. Mortality was higher in the elderly in all the head injury severity subgroups. Young subjects with a Glasgow Coma Scale (GCS) score of less than or equal to 8 tended to benefit from ICU treatment whereas patients 75 and over did not, regardless of their severity of injury. For these patients who were in the 65-74 age group, the data suggested that some benefit was likely. Patients 75 and older were significantly less likely to survive surgical intervention than younger patients. We conclude that it is valid to treat patients in the age group 65-74 years as a separate group from those patients 75 and older. Patients in this younger subset of the elderly may benefit from ICU treatment or surgical intervention. However, the patients in our older subset of elderly patients clearly did not, and they had a significantly higher risk of surgical mortality.
