Abstract
Traumatic brain injury (TBI) remains a significant cause of morbidity and mortality in children despite advances in prevention and mitigation strategies. Transcranial Doppler (TCD) ultrasound measures cerebral arterial circulation and allows for the calculation of pulsatility indices (PIs), which provides an assessment of cerebral blood flow changes. Yet, the use of PIs in children with TBI is not well understood. In this study, we defined the day-to-day (DTD) PI change of the anterior cerebral circulation and describe its relationship with injury characteristics and neurocognitive outcomes in children with TBI. A prospective observational parent study of 42 children, 2 months to 15 years of age, with mild or moderate-severe TBI who had serial TCDs provided data for this analysis. Both the mean and variation of DTD PI change were evaluated in the context of injury severity, injury sidedness, and neurocognitive outcome. In those with a unilateral injury, a larger mean DTD PI change in both the injured and uninjured side was found in those with a worse Glasgow Outcome Scale-Extended Pediatrics score at discharge. A larger variation in PI was associated with a worse neurocognitive outcome, irrespective of injury severity. Therefore, the mean and variation of DTD PI change may serve as a potential cerebral vascular biomarker of ongoing secondary injury. The use of PI measurements in the monitoring of children with TBI may provide clinicians with new diagnostic and prognostic insights to inform therapeutic interventions and recovery strategies. However, a larger prospective study is needed to confirm these findings and elucidate potential mechanistic links between DTD PI and clinical outcome measures. To our knowledge, this study is the first of its kind to evaluate the use of PI changes in cerebral vasculature in pediatric TBI patients admitted to the hospital.

Abstract
AIMS The provision of rehabilitation services for people with disorders of consciousness (DoC) may vary due to geographical, financial, and political factors. The extent of this variability and the implementation of treatment standards across countries is unknown. This study explored international neurorehabilitation systems for people with DoC. METHODS An online survey (SurveyMonkey®) was disseminated to all members of the International Brain Injury Association (IBIA) DoC Special Interest Group (SIG) examining existing rehabilitation systems and access to them. RESULTS Respondents (n = 35) were from 14 countries. Specialized neurorehabilitation was available with varying degrees of access and duration. Commencement of specialized neurorehabilitation averaged 3-4 weeks for traumatic brain injury (TBI) and 5-8 weeks for non-traumatic brain injury (nTBI) etiologies. Length of stay in inpatient rehabilitation was 1-3 months for TBI and 4-6 months for nTBI. There were major differences in access to services and funding across countries. The majority of respondents felt there were not enough resources in place to provide appropriate neurorehabilitation. CONCLUSIONS There exists inter-country differences for DoC neurorehabilitation after severe acquired brain injury. Further work is needed to implement DoC treatment standards at an international level.

Abstract
OBJECTIVE This study examined whether Icelandic female athletes in contact sports, based their self-reported concussion history on adequate medical definitions, by assessing self-reported concussion history with and without a definition of concussion. Another aim was to examine whether currently active athletes were more knowledgeable of concussions than retired athletes. METHODS Participants (age = 26.9, SD = 7.1) were 508 former (34.5%) and current (65.5%) elite female athletes in soccer (41%), handball (30.6%), basketball (19.1%), ice hockey (4.5%) and combat sports (4.7%). An online questionnaire (QuestionPro) was distributed to females in contact sports (snowball sampling). Participants later came for an in-person interview where the authenticity of previous responses was confirmed. In the questionnaire, participants answered background questions and questions about concussion history. First, they reported the total number of sustained concussions without a prompt. They reported the number of sustained concussions again after reading a definition of concussion. Participants could not correct their previous answers. Pearson's Chi-square was used for group comparisons. RESULTS The prevalence of reported concussions increased from 40.2% to 64.8% following a definition. There was no significant difference in how many participants changed their answer when asked about sustaining SRCs before and after reading the definition based on whether the participants were still competitive or retired X 2(1) = 0.69, p = 0.41. CONCLUSIONS Our data suggest that understanding of concussions is inadequate among female athletes. Self-report will continue to be an essential source of clinical information and prompting with a definition can increase the reliability of self-reported concussions.

Abstract
OBJECTIVE To identify barriers and supports that caregivers of individuals with military-related traumatic brain injury (TBI) encounter when navigating the military healthcare system; this information will be used as the foundation of a new patient-reported outcome measure. SETTING Community. PARTICIPANTS Forty-five caregivers of service members and veterans (SMV) who sustained a medically documented mild, moderate, severe, or penetrating TBI. DESIGN Latent content analysis. MAIN MEASURES Nine focus group discussions of barriers and supports to navigating the military healthcare system and community resources. RESULTS Latent content analysis indicated that caregivers discussed barriers (66%) and supports (34%) to obtaining care within the military healthcare system and the community. Caregivers most frequently discussed SMVs' interactions with healthcare, their own interactions with healthcare, family care, and community organizations. CONCLUSIONS Caregivers confront numerous challenges while pursuing healthcare services. Although much of the discussion focused on barriers and perceived unmet needs within the military healthcare system, caregivers also recognized supports within the military healthcare system and general community. Increased attention to accessibility and quality of services, as well as reducing financial burden, can lead to improved health-related quality of life for caregivers and their SMVs.

Abstract
OBJECTIVETraumatic brain injury (TBI)-the "silent epidemic"-contributes to worldwide death and disability more than any other traumatic insult. Yet, TBI incidence and distribution across regions and socioeconomic divides remain unknown. In an effort to promote advocacy, understanding, and targeted intervention, the authors sought to quantify the case burden of TBI across World Health Organization (WHO) regions and World Bank (WB) income groups.METHODSOpen-source epidemiological data on road traffic injuries (RTIs) were used to model the incidence of TBI using literature-derived ratios. First, a systematic review on the proportion of RTIs resulting in TBI was conducted, and a meta-analysis of study-derived proportions was performed. Next, a separate systematic review identified primary source studies describing mechanisms of injury contributing to TBI, and an additional meta-analysis yielded a proportion of TBI that is secondary to the mechanism of RTI. Then, the incidence of RTI as published by the Global Burden of Disease Study 2015 was applied to these two ratios to generate the incidence and estimated case volume of TBI for each WHO region and WB income group.RESULTSRelevant articles and registries were identified via systematic review; study quality was higher in the high-income countries (HICs) than in the low- and middle-income countries (LMICs). Sixty-nine million (95% CI 64-74 million) individuals worldwide are estimated to sustain a TBI each year. The proportion of TBIs resulting from road traffic collisions was greatest in Africa and Southeast Asia (both 56%) and lowest in North America (25%). The incidence of RTI was similar in Southeast Asia (1.5% of the population per year) and Europe (1.2%). The overall incidence of TBI per 100,000 people was greatest in North America (1299 cases, 95% CI 650-1947) and Europe (1012 cases, 95% CI 911-1113) and least in Africa (801 cases, 95% CI 732-871) and the Eastern Mediterranean (897 cases, 95% CI 771-1023). The LMICs experience nearly 3 times more cases of TBI proportionally than HICs.CONCLUSIONSSixty-nine million (95% CI 64-74 million) individuals are estimated to suffer TBI from all causes each year, with the Southeast Asian and Western Pacific regions experiencing the greatest overall burden of disease. Head injury following road traffic collision is more common in LMICs, and the proportion of TBIs secondary to road traffic collision is likewise greatest in these countries. Meanwhile, the estimated incidence of TBI is highest in regions with higher-quality data, specifically in North America and Europe.

Abstract
BACKGROUND Mild traumatic brain injury (mTBI) has been associated with ongoing problems in children and young people. However, there remains to be considerable debate regarding whether outcomes are a result of brain impairment, or simply reflect preinjury characteristics of the child or family. To reliably assess outcomes, an appropriate control group is required. AIMS This study aimed to identify the preinjury characteristics of children with mTBI, and to examine whether an "other injury to the head" group is an appropriate comparison to control for preinjury characteristics of children with mTBI. METHOD Parents of 290 children admitted to the emergency department with either a diagnosis of mTBI (n = 186, M = 6.44 years) or a superficial injury to the head (SIH) (n = 104, M = 5.40 years) were assessed. Parents completed three questionnaires examining behavioral problems (Clinical Assessment of Behavior), parental stress (Parenting Stress Index), and background variables (e.g., medical issues, socioeconomic factors). RESULTS A series of chi-square analyses and multivariate analysis of variance tests revealed no differences for behavior, parental stress, and other preexisting problems between children with mTBI and those with SIH. CONCLUSIONS Children who experience a mTBI event present similarly to individuals with a SIH, and SIH is an appropriate comparison group to examine the outcomes of childhood mTBI, as it may help minimize any confounding effects of preexisting issues associated with mTBI.

Abstract
Impaired cognitive function has been associated with criminal behavior. In Canada it is unknown the extent to which this disorder affects federal inmates or its impact on key correctional outcomes. In this study, 488 incoming male offenders were assessed on the Cognistat, a neuropsychological screening tool. Twenty-five percent of offenders were found to have some level of cognitive deficit. Lower levels of educational achievement, unstable employment history, learning disability, serious alcohol problems, and symptoms of Attention Deficit Hyperactivity Disorder (ADHD) were significantly associated with the presence of cognitive deficits in this sample. Although there was a significant trend for offenders with cognitive deficits to have more admissions to segregation, level of cognitive deficit was not consistently related to rates of institutional charges or rates of completion of required correctional programs. On release, cognitive deficits were not related to returns to custody or returns to custody with an offence. These results indicate that while offenders with cognitive deficits may require assistance with educational upgrading and employment to improve their reintegration potential, they do not pose a particular management problem in the community after release relative to offenders without cognitive deficits.

Abstract
The biochemical and cellular events that lead to secondary neural damage after traumatic brain injury (TBI) contribute to long-term disabilities, including memory deficits. There is a need to search for single and/or combined treatments aimed at reducing these TBI-related disfunctions. The effects of citicoline and of voluntary physical exercise in a running wheel (3 weeks), alone or in combination, on TBI-related short-term (3 h) and long-term (24 h) object recognition memory (ORM) deficits and on neurogenesis and neuroprotection were examined using a rodent model of TBI (controlled cortical impact injury). Citicoline improved memory deficits at the two times tested, while physical exercise only in the long-term test. Physical exercise had a clear neuroprotective effect as indicated by reduced interhemispheric differences in hippocampal formation and lateral ventricle volumes and in density of mature neurons in the hilus of the dentate gyrus and the perirhinal cortex. Physical exercise also increased cell proliferation and neurogenesis in the granular cell layer of the dentate gyrus. Some degree of neuroprotection of citicoline was suggested by reduced interhemispheric differences in the volume of the hippocampal formation. Contrary to what was expected, the effects of citicoline and physical exercise did not sum up. Further, a negative interference between both treatments was found in several behavioral and histological variables. The promising profiles of both treatments as therapeutic tools in TBI when applied singly underscore the need to perform further works looking for other combined treatment regimens that increase the benefit of each treatment alone.

Abstract
OBJECTIVES Health consequences of shaken baby syndrome, or pediatric abusive head trauma (AHT), can be severe and long-lasting. We aimed to estimate the multiyear medical cost attributable to AHT. METHODS Using Truven Health MarketScan data, 2003-2011, we identified children 0 to 4 years old with commercial or Medicaid insurance and AHT diagnoses. We used exact case-control matching based on demographic and insurance characteristics such as age and health plan type to compare medical care between patients with and without AHT diagnoses. Using regression models, we assessed service use (ie, average annual number of inpatient visits per patient) and inpatient, outpatient (including emergency department), drug, and total medical costs attributable to an AHT diagnosis during the 4-year period after AHT diagnosis. RESULTS We assessed 1209 patients with AHT and 5895 matched controls. Approximately 48% of patients with AHT received inpatient care within 2 days of initial diagnosis, and 25% were treated in emergency departments. AHT diagnosis was associated with significantly greater medical service use and higher inpatient, outpatient, drug, and total costs for multiple years after the diagnosis. The estimated total medical cost attributable to AHT in the 4 years after diagnosis was $47,952 (95% confidence interval [CI], $40,219-$55,685) per patient with AHT (2012 US dollars) and differed for commercially insured ($38,231 [95% CI, $29,898-$46,564]) and Medicaid ($56,691 [95% CI, $4290-$69,092]) patients. CONCLUSIONS Children continue to have substantial excess medical costs for years after AHT. These estimates exclude related nonmedical costs such as special education and disability that also are attributable to AHT.

Abstract
OBJECTIVES To systematically review the literature on dating subdural hematomas (SDHs) on CT and MRI scans. METHODS We performed a systematic review in MEDLINE, EMBASE and Cochrane to search for articles that described the appearance of SDHs on CT or MRI in relation to time between trauma and scanning. Two researchers independently screened the articles, assessed methodological quality and performed data extraction. Medians with interquartile ranges were calculated. Differences were tested with a Mann-Whitney U or Kruskal-Wallis H test. RESULTS We included 22 studies describing 973 SDHs on CT and 4 studies describing 83 SDHs on MRI. Data from 17 studies (413 SDHs) could be pooled. There were significant differences between time intervals for the different densities on CT (p<0.001). Time interval differed significantly between children and adults for iso- and hypodensity (p=0.000) and hyperdensity (p=0.046). Time interval did not differ significantly between abused and non-abused children. On MRI, time intervals for different signal intensities on T1 and T2 did not differ significantly (p=0.108 and p=0.194, respectively). CONCLUSIONS Most time intervals of the different appearances of SDHs on CT and MRI are broad and overlapping. Therefore CT or MRI findings cannot be used to accurately date SDHs.

Abstract
Traumatic brain injury (TBI) causes significant mortality, long term disability and psychological symptoms. Gene therapy is a promising approach for treatment of different pathological conditions. Here we tested chitosan and polyethyleneimine (PEI)-coated magnetic micelles (CP-mag micelles or CPMMs), a potential MRI contrast agent, to deliver a reporter DNA to the brain after mild TBI (mTBI). CPMM-tomato plasmid (ptd) conjugate expressing a red-fluorescent protein (RFP) was administered intranasally immediately after mTBI or sham surgery in male SD rats. Evans blue extravasation following mTBI suggested CPMM-ptd entry into the brain via the compromised blood-brain barrier. Magnetofection increased the concentration of CPMMs in the brain. RFP expression was observed in the brain (cortex and hippocampus), lung and liver 48 h after mTBI. CPMM did not evoke any inflammatory response by themselves and were excreted from the body. These results indicate the possibility of using intranasally administered CPMM as a theranostic vehicle for mTBI. From the clinical editor: In this study, chitosan and PEI-coated magnetic micelles (CPMM) were demonstrated as potentially useful vehicles in traumatic brain injury in a rodent model. Magnetofection increased the concentration of CPMMs in the brain and, after intranasal delivery, CPMM did not evoke any inflammatory response and were excreted from the body.

Abstract
PRIMARY OBJECTIVES To assess long-term effects of early traumatic brain injury (TBI) on mental health, cognition, behaviour and adjustment and to identify prognostic factors. METHODS AND PROCEDURES A 1-year nationwide cohort of all 0-19 year old Icelandic children and adolescents diagnosed with TBI in 1992-1993 (n = 550) received a questionnaire with clinical outcome scales and questions on TBI and socio-economic status (SES) by mail ∼16 years post-injury. A control group (n = 1232), newly selected from the National Registry, received the same questionnaire. Non-respondents answered a shorter version by telephone. Overall participation was 67%. MAIN OUTCOMES AND RESULTS Medically confirmed and self-reported TBI was reflected in worse outcome. Force of impact, number and severity of TBIs predicted poorer results. Parental SES and demographic factors had limited effects. Not reporting early, medically confirmed TBI did not exclude cognitive sequelae. In self-reported disability, absence of evaluation for compensation was not linked to outcome. CONCLUSIONS Clinical outcome was consistent with late complaints attributed to early TBI. TBI-related variables had greater prognostic value than other factors. Self-reporting of TBI sustained very early in life needs supplementary information from parents and medical records. More consistency in compensation evaluations following paediatric TBI is indicated.

Abstract
OBJECTIVE Abusive head trauma (AHT) is a leading cause of severe injury in maltreated children in the United States. There is little research from nationally representative datasets available to characterize young children who had AHT compared to non-abusive head trauma (NAHT). METHODS Using the recent CDC AHT case definition, we performed a retrospective analysis of 2000, 2003, 2006 and 2009 hospitalization data using the Kids' Inpatient Database (KID) from the Healthcare Cost and Utilization Project. Logistic regression was used to compare AHT to NAHT patients <2 years of age. Socio-demographic data and indicators of socioeconomic status (i.e., insurance status and household income), presence of chronic conditions, injury severity (i.e., length of hospital stay and vital status), hospital specialization (i.e., hospital type), hospital region, and season of admission were used as independent variables. RESULTS A weighted sample of 7,603 AHT and 25,339 NAHT patients was identified. National rates for AHT were 39.8 per 100,000 population for children <1 year and 6.8 per 100,000 population for children 1 year old. Compared to NAHT, children with AHT were more often <1 year of age (adjusted odds ratio [aOR]=2.66; 95% confidence interval [CI]: 2.35-3.01), male (aOR=1.10; 95% CI: 1.01-1.20), enrolled in Medicaid (aOR=2.78; 95% CI: 2.49-3.11), hospitalized longer (aOR=8.26; 95% CI: 7.24-9.43), died during hospitalization (aOR=5.12; 95% CI: 4.01-6.53), and seen at children's hospitals (aOR=1.97; 95% CI: 1.63-2.38) and hospitals outside the Northeast [aOR=2.65 (95% CI: 2.10-3.33) for the Midwest, 1.90 (95% CI: 1.52-2.38) for the South and 1.93 (95% CI: 1.45-2.57) for the West, respectively]. CONCLUSIONS The results confirm that injuries from AHT are more severe and more often lethal than other head injuries. Socioeconomically disadvantaged families with children <1 year are an important focus for primary prevention. The associations of AHT, compared to NAHT with hospital type and hospital region warrant further investigation. Referral or reporting patterns, or true differences in the incidence may contribute to the identified associations.

Abstract
Traumatic injury to the brain (TBI) results in a complex set of responses involving various symptoms and long-term consequences. TBI of any form can cause cognitive, behavioral and immunologic changes in later life, which underscores the problem of underdiagnosis of mild TBI that can cause long-term neurological deficits. TBI disrupts the blood–brain barrier (BBB) leading to infiltration of immune cells into the brain and subsequent inflammation and neurodegeneration. TBI-induced peripheral immune responses can also result in multiorgan damage. Despite worldwide research efforts, the methods of diagnosis, monitoring and treatment for TBI are still relatively ineffective. In this review, we delve into the mechanism of how TBI-induced central and peripheral immune responses affect the disease outcome and discuss recent developments in the continuing effort to combat the consequences of TBI and new ways to enhance repair of the damaged brain.

Abstract
Traumatic brain injury (TBI) is an important health issue with high prevalence. The most common type of TBI is mild TBI (MTBI). MTBI is known as a condition with self-limited symptoms; however, it could cause some structural abnormalities of brain and become complicated. Visible structural brain damage could have an important effect on recovery after MTBI, but the outcome is not fully understood. This study investigated the clinical course of MTBI patients with the existence of contusion in computed tomography (CT) imaging. Fifty patients with MTBI and simultaneous brain contusion in CT scan were enrolled according to specific exclusion criteria in 14 month. Patients were followed up for two weeks after their first arrival for neurosurgical interventions, decreased level of consciousness, and other neurological complications. Presence of neurological symptoms increased duration of hospital stay and number of CT scans. Forty-two percent of MTBI patients with contusion did not have any objective neurological signs. Fifty percent returned to the hospital with neurologic symptoms and signs. Leading causes were headache followed by seizure and dizziness. Rehospitalization was increased in the patients with altered level of consciousness. The size of brain contusion increased in two patients without further need for neurosurgical intervention. Contusion alone did not worsen the prognosis of patients in short-term follow-up and did not cause neurosurgical interventions.
