    To describe the Teen Online Problem Solving-Teen Only (TOPS-TO) intervention relative to the original Teen Online Problem Solving-Family (TOPS-F) intervention, to describe a randomized controlled trial to assess intervention efficacy, and to report feasibility and acceptability of the TOPS-TO intervention. Research method and design: This is a multisite randomized controlled trial, including 152 teens (49 TOPS-F, 51 TOPS-TO, 52 IRC) between the ages of 11-18 who were hospitalized for a moderate to severe traumatic brain injury in the previous 18 months. Assessments were completed at baseline, 6-months post baseline, and 12-months post baseline. Data discussed include adherence and satisfaction data collected at the 6-month assessment (treatment completion) for TOPS-F and TOPS-TO. Adherence measures (sessions completed, dropout rates, duration of treatment engagement, and rates of program completion) were similar across treatment groups. Overall, teen and parent reported satisfaction was high and similar across groups. Teens spent a similar amount of time on the TOPS website across groups, and parents in the TOPS-F spent more time on the TOPS website than those in the TOPS-TO group (p = .002). Parents in the TOPS-F group rated the TOPS website as more helpful than those in the TOPS-TO group (p = .05). TOPS-TO intervention is a feasible and acceptable intervention approach. Parents may perceive greater benefit from the family based intervention. Further examination is required to understand the comparative efficacy in improving child and family outcomes, and who is likely to benefit from each approach.

    To examine the efficacy of teen online problem solving (TOPS) in improving executive function (EF) deficits following traumatic brain injury (TBI) in adolescence. Families of adolescents (aged 11-18 years) with moderate to severe TBI were recruited from the trauma registry of 2 tertiary-care children's hospitals and then randomly assigned to receive TOPS (n = 20), a cognitive-behavioral, skill-building intervention, or access to online resources regarding TBI (Internet resource comparison; n = 21). Parent and teen reports of EF were assessed at baseline and a posttreatment follow-up (mean = 7.88 months later). Improvements in self-reported EF skills were moderated by TBI severity, with teens with severe TBI in the TOPS treatment reporting significantly greater improvements than did those with severe TBI in the Internet resource comparison. The treatment groups did not differ on parent ratings of EF at the follow up. Findings suggest that TOPS may be effective in improving EF skills among teens with severe TBI.

    To report the results of a randomized clinical trial of teen online problem-solving (TOPS) meant to improve behavioral outcomes of adolescents with traumatic brain injury (TBI). A randomized clinical trial was conducted to compare the efficacy of TOPS with access to Internet resources in teenagers with TBI in improving parent and self-reported behavior problems and parent-teen conflicts. Participants included 41 adolescents aged 11 to 18 years (range: 11.47-17.90 years) who had sustained a moderate-to-severe TBI between 3 and 19 months earlier. Teens in the TOPS group received 10 to 14 online sessions that provided training in problem-solving, communication skills, and self-regulation. Outcomes were assessed before treatment and at a follow-up assessment an average of 8 months later. Groups were compared on follow-up scores after we controlled for pretreatment levels. Injury severity and socioeconomic status were examined as potential moderators of treatment efficacy. Forty-one participants provided consent and completed baseline assessments, and follow-up assessments were completed for 35 participants (16 TOPS, 19 Internet resource comparison). The TOPS group reported significantly less parent-teen conflict at follow-up than did the Internet-resource-comparison group. Improvements in teen behavior after TOPS were moderated by injury severity; there were greater improvements in the teens' internalizing symptoms after TOPS among adolescents with severe TBI. Family socioeconomic status also moderated the efficacy of TOPS in improving behavior problems reported by both parents and teens, although the nature of the moderation effects varied. Our findings suggest that TOPS contributes to improvements in parent-teen conflict generally and parent and self-reported teen behavior problems for certain subsets of participants.

    Objective Investigate effectiveness of an online Counselor-Assisted Problem-Solving (CAPS) intervention on family functioning after traumatic brain injury (TBI). Methods Participants were randomized to CAPS (n = 65) or internet resource comparison (IRC; n = 67). CAPS is a counselor-assisted web-based program. IRC was given access to online resources. Outcomes were examined 6 months, 12 months, and 18 months after baseline. Injury severity, age, and SES were examined as moderators. Results A main effect of time was noted for teen-reported conflict and parent-reported problem solving. CAPS had decreased parent-reported conflict and a reduction in parental effective communication. Effects were specific to subsets of the sample. Conclusions CAPS, a family-based problem-solving intervention designed to address problem behaviors, had modest effects on some aspects of family functioning, when compared to IRC. Effects were generally limited to subsets of the families and were not evident across all follow-up assessments. PMID:26461100

    To broadly examine the literature to identify vision interventions following mild traumatic brain injury. Objectives are to identify: (1) evidence-informed interventions for individuals with visual dysfunction after mild traumatic brain injury; (2) professions providing these interventions; (3) gaps in the literature and areas for further research. A scoping review was conducted of four electronic databases of peer-reviewed literature from the databases earliest records to June 2017. Articles were included if the study population was mild traumatic brain injury/concussion and a vision rehabilitation intervention was tested. Two independent reviewers screened articles for inclusion, extracted data, and identified themes. The initial search identified 3111 records. Following exclusions, 22 articles were included in the final review. Nine studies evaluated optical devices, such as corrective spectacles, contact lenses, prisms, or binasal occlusion. Two studies assessed vision therapy. Ten studies examined vision therapy using optical devices. One study investigated hyperbaric oxygen therapy. Optometrists performed these interventions in most of the studies. Future research should address quality appraisal of this literature, interventions that include older adult and pediatric populations, and interdisciplinary interventions. There are promising interventions for vision deficits following mild traumatic brain injury. However, there are multiple gaps in the literature that should be addressed by future research. Implications for Rehabilitation Mild traumatic brain injury may result in visual deficits that can contribute to poor concentration, headaches, fatigue, problems reading, difficulties engaging in meaningful daily activities, and overall reduced quality of life. Promising interventions for vision rehabilitation following mild traumatic brain injury include the use of optical devices (e.g., prism glasses), vision or oculomotor therapy (e.g., targeted exercises to

    Motor vehicle crashes (MVCs) are a leading cause of morbidity and mortality in teens. Alabama has been in the Top 5 states for MVC fatality rate among teens in the United States for several years. Twelve years of teen MVC deaths and injuries were evaluated. Our hypothesis is that the teen driving motor vehicle-related deaths and injuries have decreased related to legislative and community awareness activities. A retrospective analysis of Alabama teen MVC deaths and injury for the years 2000 to 2011 was conducted. MVC data were obtained from a Fatality Analysis Reporting System data set managed by the Center for Advanced Public Safety at the University of Alabama. A Lowess regression-scattergram analysis was used to identify period specific changes in deaths and injury over time. Statistical analysis was conducted using True Epistat 5.0 software. When the Lowess regression was applied, there was an obvious change in the trend line in 2007. To test that observation, we then compared medians in the pre-2007 and post-2007 periods, which validated our observation. Moreover, it provided a near-even number of observations for comparison. The Spearman rank correlation was used to test for correlation of deaths and injury over time. The Mann-Whitney U-test was used to evaluate median differences in deaths and injury comparing pre-2007 and post-2007 data. Alabama teen MVC deaths and injury demonstrated a significant negative correlation over the 12-year period (Rs for deaths and injury, -0.87 [p teen driver deaths and injury have decreased during the 12-year study period, most notably after 2006. Factors that may have contributed to this trend may include stricter laws for teen drivers (enacted in 2002 and updated in 2010), less teen driving because of a nationwide economic downturn, delayed licensing in teens, steady improvements in overall seat belt use, and heightened public awareness of risky behaviors in teen driving.

    High levels of youth employment, workplace hazards, and characteristics unique to adolescents contribute to a relatively high incidence of injuries among teens in the restaurant industry. This article discusses the ProSafety model of injury prevention among teen restaurant workers. Through integration with an existing career and technical education program, the ProSafety project seeks to prevent occupational injuries among the teen worker population through classroom safety education and internship skills reinforcement. ProSafety is the product of an innovative collaboration with occupational health nurses, business professionals, educators, and government. Its approach is derived from Social Cognitive Theory, is consistent with key values and strategies of occupational health nurses, and provides lessons for practitioners seeking to reduce occupational injuries in food service or among other populations of adolescent workers.

    To examine the results of a randomized clinical trial (RCT) of Teen Online Problem Solving (TOPS), an online problem solving therapy model, in increasing problem-solving skills and decreasing depressive symptoms and global distress for caregivers of adolescents with traumatic brain injury (TBI). Families of adolescents aged 11-18 who sustained a moderate to severe TBI between 3 and 19 months earlier were recruited from hospital trauma registries. Participants were assigned to receive a web-based, problem-solving intervention (TOPS, n = 20), or access to online resources pertaining to TBI (Internet Resource Comparison; IRC; n = 21). Parent report of problem solving skills, depressive symptoms, global distress, utilization, and satisfaction were assessed pre- and posttreatment. Groups were compared on follow-up scores after controlling for pretreatment levels. Family income was examined as a potential moderator of treatment efficacy. Improvement in problem solving was examined as a mediator of reductions in depression and distress. Forty-one participants provided consent and completed baseline assessments, with follow-up assessments completed on 35 participants (16 TOPS and 19 IRC). Parents in both groups reported a high level of satisfaction with both interventions. Improvements in problem solving skills and depression were moderated by family income, with caregivers of lower income in TOPS reporting greater improvements. Increases in problem solving partially mediated reductions in global distress. Findings suggest that TOPS may be effective in improving problem solving skills and reducing depressive symptoms for certain subsets of caregivers in families of adolescents with TBI.

    Crashes are the leading cause of death for teens, and parent-based interventions are a promising approach. We assess the effectiveness of Steering Teens Safe, a parent-focused program to increase safe teen driving. Steering Teens Safe aimed to improve parental communication with teens about safe driving using motivational interviewing techniques in conjunction with 19 safe driving lessons. A randomized controlled trial involved 145 parent-teen dyads (70 intervention and 75 control). Intervention parents received a 45-minute session to learn the program with four follow-up phone sessions, a DVD, and a workbook. Control parents received a standard brochure about safe driving. Scores were developed to measure teen-reported quantity and quality of parental communication about safe driving. The main outcome measure was a previously validated Risky Driving Score reported by teens. Because the Score was highly skewed, a generalized linear model based on a gamma distribution was used for analysis. Intervention teens ranked their parent's success in talking about driving safety higher than control teens (p = 0.035) and reported that their parents talked about more topics (non-significant difference). The Risky Driving Score was 21% lower in intervention compared to control teens (85% CI = 0.60, 1.00). Interaction between communication quantity and the intervention was examined. Intervention teens who reported more successful communication had a 42% lower Risky Driving Score (95% CI = 0.37, 0.94) than control parents with less successful communication. This program had a positive although not strong effect, and it may hold the most promise in partnership with other programs, such as Driver's Education or Graduated Driver's License policies.

    To identify factors reported with negative and positive outcomes for caregivers of the traumatic brain injury and spinal cord injury cohorts, to investigate what interventions have been studied to support carers and to report what effectiveness has been found. Scoping systematic review. Electronic databases and websites were searched from 1990 to December 2015. Studies were agreed for inclusion using pre-defined criteria. Relevant information from included studies was extracted and quality assessment was completed. Data were synthesised using qualitative methods. A total of 62 studies reported caregiver outcomes for the traumatic brain injury cohort; 51 reported negative outcomes and 11 reported positive outcomes. For the spinal cord injury cohort, 18 studies reported caregiver outcomes; 15 reported negative outcomes and three reported positive outcomes. Burden of care was over-represented in the literature for both cohorts, with few studies looking at factors associated with positive outcomes. Good family functioning, coping skills and social support were reported to mediate caregiver burden and promote positive outcomes. A total of 21 studies further described interventions to support traumatic brain injury caregivers and four described interventions to support spinal cord injury caregivers, with emerging evidence for the effectiveness of problem-solving training. Further research is required to explore the effects of injury severity of the care recipient, as well as caregiver age, on the outcome of the interventions. Most studies reported negative outcomes, suggesting that barriers to caregiving have been established, but not facilitators. The interventions described to support carers are limited and require further testing to confirm their effectiveness.

    As part of a statewide campaign, we surveyed physician attitudes and practice regarding teen driving safety before and after a brief intervention designed to facilitate in office counseling. A 31-item self-administered survey was mailed to Connecticut physicians, and this was followed by a mailing of teen driving safety materials to physician practices in the state. A postintervention survey was mailed 8 months after the presurvey. A total of 102 physicians completed both the pre and postsurveys. Thirty-nine percent (39%) reported having had a teen in their practice die in a motor vehicle crash in the presurvey, compared with 49% in the postsurvey. Physician counseling increased significantly for a number of issues: driving while impaired from 86% to 94%; restrictions on teen driving from 53% to 64%; teen driving laws from 53% to 63%; safe vehicle from 32% to 42%; parents model safe driving from 29% to 44%; and teen-parent written contract from 15% to 37%. At baseline, the majority of physicians who provide care to teenagers in Connecticut report discussing and counseling teens on first wave teen driver safety issues (seat belts, alcohol use), but most do not discuss graduate driver licensing laws or related issues. After a brief intervention, there was a significant increase in physician counseling of teens on teen driving laws and on the use of teen-parent contracts. Additional interventions targeting physician practices can improve physician counseling to teens and their parents on issues of teen driving safety.

    Full Text Available Facilitating functional recovery following brain injury is a key goal of neurorehabilitation. Direct, objective measures of changes in the brain are critical to understanding how and when meaningful changes occur, however, assessing neuroplasticity using brain based results remains a significant challenge. Little is known about the underlying changes in functional brain networks that correlate with cognitive outcomes in traumatic brain injury (TBI. The purpose of this pilot study was to assess the feasibility of an intensive three month cognitive intervention program in individuals with chronic TBI and to evaluate the effects of this intervention on brain-behavioral relationships. We used tools from graph theory to evaluate changes in global and local brain network features prior to and following cognitive intervention. Network metrics were calculated from resting state electroencephalographic (EEG recordings from 10 adult participants with mild to severe brain injury and 11 age and gender matched healthy controls. Local graph metrics showed hyper-connectivity in the right inferior frontal gyrus and hypo-connectivity in the left inferior frontal gyrus in the TBI group at baseline in comparison with the control group. Following the intervention, there was a statistically significant increase in the composite cognitive score in the TBI participants and a statistically significant decrease in functional connectivity in the right inferior frontal gyrus. In addition, there was evidence of changes in the brain-behavior relationships following intervention. The results from this pilot study provide preliminary evidence for functional network reorganization that parallels cognitive improvements after cognitive rehabilitation in individuals with chronic TBI.

    Injury is a leading cause of death for infants and children. Teen mothering has been shown to put children at increased risk of injury. The mothers of teen parents often play a predominant role in the lives and caregiving of the children born to their children. This article presents the findings of three focus groups conducted with 21 mothers of teen parents. Grounded theory methodology was used to explore family dynamics and how they relate to injury prevention beliefs and practices regarding infants and children. Our findings revealed the difficulty mothers of teen parents and the teens themselves have in adjusting to the knowledge of the pregnancy. Unique barriers to injury prevention were also uncovered. Our findings provide evidence for the need of a multigenerational approach to programs aimed at improving the safety and well-being of children in this context. Copyright © 2014 Elsevier Ltd.

    From the advent of airbags to electronic stability control, technological advances introduced into automobile design have significantly reduced injury and death from motor vehicle crashes. These advances are especially pertinent among teen drivers, a population whose leading cause of death is motor vehicle crashes. Recently developed advanced driver assistance systems (ADAS) have the potential to compensate for skill deficits and reduce overall crash risk. Yet, ADAS is only effective if drivers are willing to use it. Limited research has been conducted on the suitability of ADAS for teen drivers. The goal of this study is to identify teen drivers' perceived need for ADAS, receptiveness to in-vehicle technology, and intervention preferences. The long-term goal is to understand public perceptions and barriers to ADAS use and to help determine how these systems must evolve to meet the needs of the riskiest driving populations. Three focus groups (N = 24) were conducted with licensed teen drivers aged 16-19 years and 2 focus groups with parents of teen drivers (N = 12). Discussion topics included views on how ADAS might influence driving skills and behaviors; trust in technology; and data privacy. Discussions were transcribed; the team used conventional content analysis and open coding methods to identify 12 coding domains and code transcripts with NVivo 10. Interrater reliability testing showed moderate to high kappa scores. Overall, participants recognized potential benefits of ADAS, including improved safety and crash reduction. Teens suggested that ADAS is still developing and therefore has potential to malfunction. Many teens reported a greater trust in their own driving ability over vehicle technology. They expressed that novice drivers should learn to drive on non-ADAS-equipped cars and that ADAS should be considered a supplemental aid. Many teens felt that overreliance on ADAS may increase distracted driving or risky behaviors among teens. Parents also

    To investigate the feasibility and effectiveness of conducting two positive psychology interventions to improve mood and self-concept with survivors of traumatic brain injury (TBI), within a neuro-rehabilitation hospital. Ten patients with brain injury were randomly allocated to an intervention and control group. The efficacy of the first intervention, 'three positive things in life' was measured via Seligman's Authentic Happiness Index (AHI), at base-line, directly following the intervention and at the end of the 12-week group programme. The second intervention, the 'Value in Action (VIA) signature strengths intervention' was measured by the Head Injury Semantic Differential Scale (HISDS) at baseline and at the end of the group. Compared to baseline and control group scores, the AHI index showed an increase in the intervention group's happiness following the intervention and at the end of the 12-week programme, albeit the latter increase was non-significant. The HISDS showed non-significant improvement in self-concept and reduction in polarization of the self in the present, future and past in the second intervention. Anecdotal evidence revealed a clear improved mood following the interventions. This study shows promising results for the effectiveness of Positive Psychology interventions and methods to improve feasibility when applying this treatment within a hospital setting.

    Parents play a fundamental role in teaching their children safe driving skills to reduce risk of motor vehicle crashes, the leading cause of death for teens. Steering Teens Safe is a new parent-based intervention that equips parents with communication skills to talk about, demonstrate, and practice safe driving behaviors and skills with their teens. This implementation evaluation focuses on a sample of 83 parents who delivered Steering Teens Safe to their teens. One-, 2- and 3-month follow-up assessments were conducted with intervention parents to evaluate the self-reported quantity and quality of talking about, demonstrating, and practicing safe driving goals with teens; perceived success and benefit of the program; and barriers to implementation. Over 3 months of follow-up, parents discussed driving goals with their teens for a median of 101.5 minutes. The most frequently addressed topics were general safety principles, including distracted driving, driving in bad weather, wearing a seat belt, and being a safe passenger. Parents spent a median of 30 minutes practicing safe driving skills such as changing lanes. Sixty-seven percent of parents talked to their children about rural road safety, but just 36% demonstrated and half practiced these skills with their teens. Barriers to implementation include time and opportunity barriers and resistant attitudes of their teens. However, barriers neither affected frequency of engagement nor parents' perceived benefit and comfort in delivering the program. Parents with time/opportunity barriers also had higher practice and demonstration times than parents without these barriers. Findings indicate high acceptability among parent implementers and promise for real-world delivery. Future studies are needed to assess intervention impact.

    Electrical Bioimpedance (EBI) is a well spread technology used in clinical practice across the world. Advancements in Textile material technology with conductive textile fabrics and textile-electronics integration have allowed exploring potential applications for Wearable Measurement Sensors and Systems exploiting. The sensing principle of electrical bioimpedance is based on the intrinsic passive dielectric properties of biological tissue. Using a pair of electrodes, tissue is electrically stimulated and the electrical response can be sensed with another pair of surface electrodes. EBI spectroscopy application for cerebral monitoring of neurological conditions such as stroke and perinatal asphyxia in newborns have been justified using animal studies and computational simulations. Such studies have shown proof of principle that neurological pathologies indeed modify the dielectric composition of the brain that is detectable via EBI. Similar to stroke, Traumatic Brain Injury (TBI) also affects the dielectric properties of brain tissue that can be detected via EBI measurements. Considering the portable and noninvasive characteristics of EBI it is potentially useful for prehospital triage of TBI patients where. In the battlefield blast induced Traumatic Brain Injuries are very common. Brain damage must be assessed promptly to have a chance to prevent severe damage or eventually death. The relatively low-complexity of the sensing hardware required for EBI sensing and the already proven compatibility with textile electrodes suggest the EBI technology is indeed a candidate for developing a handheld device equipped with a sensorized textile cap to produce an examination in minutes for enabling medically-guided prompt intervention.

Unlike studies dealing with adult patients, in which mechanisms of brain injury are divided into cerebral vascular accident (CVA) and traumatic brain injury (TBI), studies on pediatric patients deal almost exclusively with traumatic brain injury, specifically caused by accidents. Here we report on the vision problems of 4 pediatric patients, ages 3 to 18 years, who were examined in the ophthalmology/optometry clinic at a children's hospital. All patients had an internally caused brain injury and after the initial insult manifested problems in at least one of the following areas: acuity, binocularity, motility (tracking or saccades), accommodation, visual fields, and visual perceptual skills. Pediatric patients can suffer from a variety of oculo-visual problems after the onset of head injury. These patients may or may not be symptomatic and can benefit from optometric intervention.

    Rehabilitation professionals have become increasingly aware that family members play a critical role in the recovery process of individuals after brain injury. In addition, researchers have begun to identify a relationship between family member caregivers' well-being and survivors' outcomes. The idea of a continuum of care or following survivors from inpatient care to community reintegration has become an important model of treatment across many hospital and community-based settings. In concert with the continuum of care, present research literature indicates that family intervention may be a key component to successful rehabilitation after brain injury. Yet, clinicians interacting with family members and survivors often feel confounded about how exactly to intervene with the broader family system beyond the individual survivor. Drawing on the systemic nature of the field of marriage and family therapy (MFT), this article provides information to assist clinicians in effectively intervening with families using theory-based interventions in community settings. First, a rationale for the utilization of systems-based, as opposed to individual-based, therapies will be uncovered. Second, historically relevant publications focusing on family psychotherapy and intervention after brain injury are reviewed and their implications discussed. Recommendations for the utilization of systemic theory-based principles and strategies, specifically cognitive behavioral therapy (CBT), narrative therapy (NT), and solution-focused therapy (SFT) will be examined. Descriptions of common challenges families and couples face will be presented along with case examples to illustrate how these theoretical frameworks might be applied to these special concerns postinjury. Finally, the article concludes with an overview of the ideas presented in this manuscript to assist practitioners and systems of care in community-based settings to more effectively intervene with the family system as a whole

    Background A small body of previous research has demonstrated that pediatric traumatic brain injury increases risk for internalizing problems, but findings have varied regarding their predictors and correlates. Methods We examined the level and correlates of internalizing symptoms in 130 teens who had sustained a complicated mild to severe TBI within the past 1 to 6 months. Internalizing problems were measured via both maternal and paternal report Child Behavior Checklist. We also measured family functioning, parent psychiatric symptoms, and post-injury teen neurocognitive function. Results Mean parental ratings of internalizing problems were within the normal range. Depending on informant, 22–26% of the sample demonstrated clinically elevated internalizing problems. In multiple and binary logistic regression models, only parent psychiatric symptoms consistently provided unique prediction of teen internalizing symptoms. For maternal but not paternal report, female gender was associated with greater internalizing problems. Conclusion Parent and teen emotional problems are associated following adolescent TBI. Possible reasons for this relationship, including the effects of TBI on the family unit, are discussed. PMID:22935574

    To gather knowledge about effective return-to-work (RTW) interventions for patients with acquired brain injury (ABI). A database search was performed in PubMed, EMBASE, PsycINFO, CINAHL and the Cochrane Library using keywords and Medical Subject Headings. Studies were included if they met inclusion criteria: adult patients with non-progressive ABI, working pre-injury and an intervention principally designed to improve RTW as an outcome. The methodological quality of included studies was determined and evidence was assessed qualitatively. Twelve studies were included, of which five were randomized controlled trials and seven were cohort studies. Nine studies had sufficient methodological quality. There is strong evidence that work-directed interventions in combination with education/coaching are effective regarding RTW and there are indicative findings for the effectiveness of work-directed interventions in combination with skills training and education/coaching. Reported components of the most effective interventions were tailored approach, early intervention, involvement of patient and employer, work or workplace accommodations, work practice and training of social and work-related skills, including coping and emotional support. Effective RTW interventions for patients with ABI are a combination of work-directed interventions, coaching/education and/or skills training. These interventions have the potential to facilitate sustained RTW for patients with ABI.

    Previous research has demonstrated the value of arts-based programs for adolescents with childhood brain disorder to facilitate social skills and participation. The current study extends this work by examining the feasibility and effectiveness of an arts-based intervention for youth with acquired brain injuries (ABI). A case study approach was used with four adolescent participants and one case control. A battery of quantitative measures were administered four and one week pre-intervention, one week post-intervention, as well six to eight month post-intervention. Improvements in pragmatic communication skills and social and participation goals were observed across intervention participants. Similar improvements were not seen with the case control participant. Results support the use of an arts-based intervention for youth with ABI to facilitate social skills and participation. Findings also highlight the need for more sensitive measures of these skills for these youth. Suggested guidelines for program implementation are provided.

    Objective : Awareness of errors is an important prerequisite in rehabilitation. Few studies have investigated rehabilitation of error awareness following acquired brain injury. Pilot research has shown that receiving feedback about errors during a computerised task of sustained attention improves performance in patients who have sustained a traumatic brain injury. In this study, a computer-based intervention training programme aimed at improving error awareness was developed. \\r\

    This systematic review sought evidence concerning the effectiveness of peer mentoring for people with traumatic brain injury. Fourteen electronic databases were searched, including PsycINFO, MEDLINE, CINAHL, EMBASE and the Cochrane Library, from inception to September 21 2016. Ten grey literature databases, PROSPERO, two trials registers, reference lists and author citations were also searched. Studies which employed a model of one-to-one peer mentoring between traumatic brain injury survivors were included. Two reviewers independently screened all titles and abstracts before screening full texts of shortlisted studies. A third reviewer resolved disagreements. Two reviewers independently extracted data and assessed studies for quality and risk of bias. The search returned 753 records, including one identified through hand searching. 495 records remained after removal of duplicates and 459 were excluded after screening. Full texts were assessed for the remaining 36 studies and six met the inclusion criteria. All were conducted in the United States between 1996 and 2012 and employed a variety of designs including two randomised controlled trials. A total of 288 people with traumatic brain injury participated in the studies. No significant improvements in social activity level or social network size were found, but significant improvements were shown in areas including behavioural control, mood, coping and quality of life. There is limited evidence for the effectiveness of peer mentoring after traumatic brain injury. The available evidence comes from small-scale studies, of variable quality, without detailed information on the content of sessions or the 'active ingredient' of the interventions.

    2009-07-01

    To point out from the literature the issues in mild traumatic brain injury outcome. METHODOLOGY-RESULTS: The literature review allows to point out several different factors involved in the difficulty to study mild traumatic brain injury: mild traumatic brain injury definition, postconcussional syndrome definition, diagnosis threshold, severity and functional symptoms outcome, neuropsychological tests, unspecific syndrome feature, individual factors, confounding factors and treatment interventions. The mild traumatic brain injury outcome study is complicated by the definitions issues and especially their practical use and by the multiplicity and the intricate interrelationships among involved factors. The individual outcome and social cost weight is widely emphasized for an event still considered as medically trivial. The well-ordered preventive interventions necessity and the targeted treatment programs need for the persisting postconcussive symptoms complete our critical review.

    MRI is invaluable in assessing the neonatal brain following suspected perinatal injury. Good quality imaging requires adaptations to both the hardware and the sequences used for adults or older children. The perinatal and postnatal details often predict the pattern of lesions sustained and should be available to aid interpretation of the imaging findings. Perinatal lesions, the pattern of which can predict neurodevelopmental outcome, are at their most obvious on conventional imaging between 1 and 2 weeks from birth. Very early imaging during the first week may be useful to make management decisions in ventilated neonates but brain abnormalities may still be subtle using conventional sequences. Diffusion-weighted imaging (DWI) is very useful for the early identification of ischaemic tissue in the neonatal brain but may underestimate the final extent of injury, particularly basal ganglia and thalamic lesions. MR imaging is an excellent predictor of outcome following perinatal brain injury and can therefore be used as a biomarker in interventional trials designed to reduce injury and improve neurodevelopmental outcome.

    Adolescent mothers in Washington, DC have a high rate of subsequent teen pregnancies, often within 24 months. Children of teen mothers are at risk for adverse psychosocial outcomes. When adolescents are strongly attached to parents, schools, and positive peers, they may be less likely to repeat a pregnancy. This study tested the efficacy of a counseling intervention delivered by cell phone and focused on postponing subsequent teen pregnancies by strengthening healthy relationships, reproductive practices, and positive youth assets. The objective of this study was to compare time to a repeat pregnancy between the intervention and usual care groups, and, secondarily, to determine whether treatment intensity influenced time to subsequent conception. Primiparous pregnant teens ages 15-19, were recruited in Washington, DC. Of 849 teens screened, 29.3% (n = 249) met inclusion criteria, consented to participate, and completed baseline measures. They were then randomized to the intervention (N = 124) or to usual care (N = 125). Intervention group teens received cell phones for 18 months of counseling sessions, and quarterly group sessions. Follow-up measures assessed subsequent pregnancy through 24 months post-delivery. A survival analysis compared time to subsequent conception in the two treatment groups. Additional models examined the effect of treatment intensity. By 24 months, 31% of the intervention and 36% of usual care group teens had a subsequent pregnancy. Group differences were not statistically significant in intent-to-treat analysis. Because there was variability in the degree of exposure of teens to the curriculum, a survival analysis accounting for treatment intensity was performed and a significant interaction with age was detected. Participants who were aged 15-17 years at delivery showed a significant reduction in subsequent pregnancy with increased levels of intervention exposure (P teen pregnancy.

    2017-01-01

    Acquired brain injury (ABI) severely affects both the injured patient and her/his family. This fact alone calls for a therapeutic approach addressing not only the individual victim of ABI but also her/his family. Additionally, the optimal outcome of posttraumatic cognitive rehabilitation may be best obtained by supplementing the institution-based cognitive training with home-based training. Moving cognitive training and other therapeutic interventions into the home environment does, however, constitute an additional challenge to the family structure and psychological wellbeing of all family members. We presently argue in favour of an increased utilization of family-based intervention programs for the families of brain injured patients - in general and especially in case of utilization of home-based rehabilitative training.

    2013-01-01

    To evaluate the efficacy of parenting interventions on child and parent behavioral and emotional outcomes for parents of children with traumatic brain injury (TBI). Systematic searches of 5 databases. Included studies were assessed for quality, and relevant data were extracted and collated. Eight articles met inclusion criteria, reporting 6 trials of interventions involving parent training for parents of children with TBI. Only 1 pre-post study trialed a version of a traditional parenting intervention. The remaining studies involved a multicomponent family problem-solving intervention. Each trial found a statistically significant intervention effect for at least 1 outcome measure. Interventions that train parents may be a useful approach to alleviate behavioral and emotional disturbances after pediatric TBI. Some evidence suggests that these interventions may help to improve parenting skill and adjustment. However, all identified studies included interventions with multiple treatment components, so the effects attributable to parent training alone remain undetermined. Further quality trials are needed to assess the unique effectiveness of parenting interventions in this population.

    There is general consensus that adults under age 65 with acquired brain injury residing in nursing homes is inappropriate, however there is a limited evidence base on the issue. Previous research has relied heavily on third-party informants and qualitative studies have been of questionable methodological quality, with no known study adopting a phenomenological approach. This study explored the lived experiences of young adults with brain injury residing in aged care facilities. Interpretative phenomenological analysis was employed to collect and analyze data from six semi-structured interviews with participants regarding their experiences of living in nursing homes. Two themes were identified, including "Corporeal prison of acquired brain injury: broken selves" and "Existential prison of the nursing home: stagnated lives". Results illustrated that young adults with acquired brain injury can experience aged care as an existential prison in which their lives feel at a standstill. This experience was characterized by feelings of not belonging in a terminal environment, confinement, disempowerment, emptiness and hope for greater autonomy through rehabilitation. It is hoped that this study will provide relevant professionals, services and policy-makers with insight into the challenges and needs of young adults with brain injury facing these circumstances. Implications for rehabilitation This study supports the contention that more home-like and age-appropriate residential rehabilitation services for young adults with acquired brain injury are needed. As development of alternative accommodation is a lengthy process, the study findings suggest that the interim implementation of rehabilitative care in nursing homes should be considered. Taken together with existing research, it is proposed that nursing home staff may require training to deliver evidence-based rehabilitative interventions to those with brain injury. The present findings add support to the call for systemic

    Several international jurisdictions allow family exemptions to graduated driver licensing passenger restrictions. The objective of this research was to examine differences in injury risk to US child passengers in crashes involving sibling versus non-sibling teen drivers, and to compare outcomes with crashes involving adult drivers. Insurance claim and telephone survey data were collected on 16 233 child passengers (representing 289 329 children) in 17 US jurisdictions. There was a trend toward higher restraint non-use by child passengers in the non-sibling group than in the sibling group (9.6% vs 4.7%; p = 0.08). Children in the sibling group had a 40% lower risk of injury than those in the non-sibling group (adjusted OR 0.60, 95% CI 0.40 to 0.90); however, injury risk was higher in the sibling group than in children traveling with adults (adjusted OR 1.57, 95% CI 1.09 to 2.26). Child passengers riding with sibling teen drivers may be safer than those riding with non-sibling teens, but not as safe as those riding with adult drivers.

    Acquired brain injury (ABI) can result in impairments in motor function, language, cognition, and sensory processing, and in emotional disturbances, which can severely reduce a survivor's quality of life. Music interventions have been used in rehabilitation to stimulate brain functions involved in movement, cognition, speech, emotions, and sensory perceptions. An update of the systematic review published in 2010 was needed to gauge the efficacy of music interventions in rehabilitation for people with ABI. To assess the effects of music interventions for functional outcomes in people with ABI. We expanded the criteria of our existing review to: 1) examine the efficacy of music interventions in addressing recovery in people with ABI including gait, upper extremity function, communication, mood and emotions, cognitive functioning, social skills, pain, behavioural outcomes, activities of daily living, and adverse events; 2) compare the efficacy of music interventions and standard care with a) standard care alone, b) standard care and placebo treatments, or c) standard care and other therapies; 3) compare the efficacy of different types of music interventions (music therapy delivered by trained music therapists versus music interventions delivered by other professionals). We searched the Cochrane Stroke Group Trials Register (January 2016), the Cochrane Central Register of Controlled Trials (CENTRAL) (2015, Issue 6), MEDLINE (1946 to June 2015), Embase (1980 to June 2015), CINAHL (1982 to June 2015), PsycINFO (1806 to June 2015), LILACS (1982 to January 2016), and AMED (1985 to June 2015). We handsearched music therapy journals and conference proceedings, searched dissertation and specialist music databases, trials and research registers, reference lists, and contacted relevant experts and music therapy associations to identify unpublished research. We imposed no language restriction. We performed the original search in 2009. We included all randomised controlled trials

    Support programs for partners of patients with acquired brain injury are necessary since these partners experience several unfavorable consequences of caregiving, such as a high burden, emotional distress, and poor quality of life. Evidence-based support strategies that can be included in these support programs are psychoeducation, skill building, problem solving, and improving feelings of mastery. A promising approach would seem to be to combine web-based support with face-to-face consultations, creating a blended care intervention. This paper outlines the protocol of a randomized controlled trial to evaluate the CARE4Carer blended care intervention for partners of patients with acquired brain injury. A multicenter two-arm randomized controlled trial will be conducted. A total of 120 partners of patients with acquired brain injury will be recruited from five rehabilitation centers in the Netherlands. The blended care intervention consists of a nine-session web-based support program and two face-to-face consultations with a social worker. Themes that will be addressed are: giving partners insight into their own situation, including possible pitfalls and strengths, learning how to cope with the situation, getting a grip on thoughts and feelings, finding a better balance in the care for the patient with acquired brain injury, thinking about other possible care options, taking care of oneself, and communication. The intervention lasts 20 weeks and the control group will receive usual care. The outcome measures will be assessed at baseline and at 24- and 40-week follow-up. The primary outcome is caregiver mastery. Secondary outcome measures are strain, burden, family functioning, emotional functioning, coping, quality of life, participation, and social network. The effect of the intervention on the primary and secondary outcome measures will be determined. Additional a process evaluation will be conducted. The findings of this study will be used to improve the care for

    2008-01-01

    BACKGROUND:Brain injury patients often exhibit learning and memory functional deficits.Long-term potentiation(LTP)is a representative index for studying learning and memory cellular models; the LTP index correlates to neural plasticity. OBJECTIVE:This study was designed to investigate correlations of learning and memory functions to LTP in brain injury patients,and to summarize the research advancements in mechanisms underlying brain functional improvements after rehabilitation intervention. RETRIEVAL STRATEGY:Using the terms "brain injuries,rehabilitation,learning and memory,long-term potentiation",manuscripts that were published from 2000-2007 were retrieved from the PubMed database.At the same time,manuscripts published from 2000-2007 were also retrieved from the Database of Chinese Scientific and Technical Periodicals with the same terms in the Chinese language.A total of 64 manuscripts were obtained and primarily screened.Inclusion criteria:studies on learning and memory,as well as LTP in brain injury patients,and studies focused on the effects of rehabilitation intervention on the two indices; studies that were recently published or in high-impact journals.Exclusion criteria:repetitive studies.LITERATURE EVALUATION:The included manuscripts primarily focused on correlations between learning and memory and LTP,the effects of brain injury on learning and memory,as well as LTP,and the effects of rehabilitation intervention on learning and memory after brain injury.The included 39 manuscripts were clinical,basic experimental,or review studies. DATA SYNTHESIS:Learning and memory closely correlates to LTP.The neurobiological basis of learning and memory is central nervous system plasticity,which involves neural networks,neural circuits,and synaptic connections,in particular,synaptic plasticity.LTP is considered to be an ideal model for studying synaptic plasticity,and it is also a classic model for studying neural plasticity of learning and memory.Brain injury

  8. Molecular Mechanisms of Neonatal Brain Injury

    Directory of Open Access Journals (Sweden)

    Claire Thornton

    2012-01-01

    Full Text Available Fetal/neonatal brain injury is an important cause of neurological disability. Hypoxia-ischemia and excitotoxicity are considered important insults, and, in spite of their acute nature, brain injury develops over a protracted time period during the primary, secondary, and tertiary phases. The concept that most of the injury develops with a delay after the insult makes it possible to provide effective neuroprotective treatment after the insult. Indeed, hypothermia applied within 6 hours after birth in neonatal encephalopathy reduces neurological disability in clinical trials. In order to develop the next generation of treatment, we need to know more about the pathophysiological mechanism during the secondary and tertiary phases of injury. We review some of the critical molecular events related to mitochondrial dysfunction and apoptosis during the secondary phase and report some recent evidence that intervention may be feasible also days-weeks after the insult.

    A relationship between reduced brain tissue oxygenation and poor outcome following severe traumatic brain injury has been reported in observational studies. We designed a Phase II trial to assess whether a neurocritical care management protocol could improve brain tissue oxygenation levels in patients with severe traumatic brain injury and the feasibility of a Phase III efficacy study. Randomized prospective clinical trial. Ten ICUs in the United States. One hundred nineteen severe traumatic brain injury patients. Patients were randomized to treatment protocol based on intracranial pressure plus brain tissue oxygenation monitoring versus intracranial pressure monitoring alone. Brain tissue oxygenation data were recorded in the intracranial pressure -only group in blinded fashion. Tiered interventions in each arm were specified and impact on intracranial pressure and brain tissue oxygenation measured. Monitors were removed if values were normal for 48 hours consecutively, or after 5 days. Outcome was measured at 6 months using the Glasgow Outcome Scale-Extended. A management protocol based on brain tissue oxygenation and intracranial pressure monitoring reduced the proportion of time with brain tissue hypoxia after severe traumatic brain injury (0.45 in intracranial pressure-only group and 0.16 in intracranial pressure plus brain tissue oxygenation group; p injury after severe traumatic brain injury based on brain tissue oxygenation and intracranial pressure values was consistent with reduced mortality and increased proportions of patients with good recovery compared with intracranial pressure-only management; however, the study was not powered for clinical efficacy. Management of severe traumatic brain injury informed by multimodal intracranial pressure and brain tissue oxygenation monitoring reduced brain tissue hypoxia with a trend toward lower mortality and more favorable outcomes than intracranial pressure-only treatment.

    The objective of this study was to examine the intervention costs of a residential community reintegration programme for patients with acquired brain injury and to compare the societal costs before and after treatment. A cost-analysis was performed identifying costs of healthcare, informal care, and productivity losses. The costs in the year before the Brain Integration Programme (BIP) were compared with the costs in the year after the BIP using the following cost categories: care consumption, caregiver support, productivity losses. Dutch guidelines were used for cost valuation. Thirty-three cases participated (72% response). Mean age was 29.8 years, 59% traumatic brain injury. The BIP costs were €68,400. The informal care and productivity losses reduced significantly after BIP (p costs per patient were €48,449. After BIP these costs were €39,773; a significant reduction (p costs after the BIP advocates the allocation of resources and, from an economic perspective, favours reimbursement of the BIP costs by healthcare insurance companies. However, this cost-analysis is limited as it does not relate costs to clinical effectiveness. :

    Facilitating functional recovery following brain injury is a key goal of neurorehabilitation. Direct, objective measures of changes in the brain are critical to understanding how and when meaningful changes occur, however, assessing neuroplasticity using brain based results remains a significant challenge. Little is known about the underlying changes in functional brain networks that correlate with cognitive outcomes in traumatic brain injury (TBI). The purpose of this pilot study was to asse...

    Following traumatic brain injury (TBI), children experience a variety of physical, motor, speech, and cognitive deficits that can have a long-term detrimental impact. The emergence and popularity of new technologies has led to research into the development of various apps, gaming systems, websites, and robotics that might be applied to rehabilitation. The objective of this narrative review was to describe the current literature regarding technologically-assisted interventions for the rehabilitation of motor, neurocognitive, behavioral, and family impairments following pediatric TBI. We conducted a series of searches for peer-reviewed manuscripts published between 2000 and 2017 that included a technology-assisted component in the domains of motor, language/communication, cognition, behavior, social competence/functioning, family, and academic/school-based functioning. Findings suggested several benefits of utilizing technology in TBI rehabilitation including facilitating engagement/adherence, increasing access to therapies, and improving generalizability across settings. There is fairly robust evidence regarding the efficacy of online family problem-solving therapy in improving behavior problems, executive functioning, and family functioning. There was less compelling, but still promising, evidence regarding the efficacy other technology for motor deficits, apps for social skills, and computerized programs for cognitive skills. Overall, many studies were limited in the rigor of their methodology due to small heterogeneous samples and lack of control groups. Technology-assisted interventions have the potential to enhance pediatric rehabilitation after TBI. Future research is needed to further support their efficacy with larger controlled trials and to identify characteristics of children who are most likely to benefit.

    The aim of this study was to explore and describe how client-centred occupational therapy interventions may support and improve the ability to use everyday technology (ET) in work tasks in people with acquired brain injury (ABI). A qualitative, descriptive multiple-case study was designed, and occupation-based interventions were provided to three working-age participants with ABI. Multiple sources were used to collect data throughout the three intervention processes, including assessments, field notes, and interviews. The Canadian Occupational Performance Measure and the Management of Everyday Technology Assessment were administered before the interventions, after the interventions and at a follow-up session 2-3 months subsequent to the interventions. The three intervention processes initially consisted of similar actions, but subsequently the actions took on a different focus and intensity for each case. All of the goals in each of the three case processes were achieved, and both perceived and observed abilities to use ET in work tasks improved. Client-centred occupational therapy interventions might have the potential to improve the ability to use ET in work tasks in people with ABI.

    Full Text Available ABSTRACT Language impairments in patients with acquired brain injury can have a negative impact on social life as well as on other cognitive domains. Discourse impairments are among the most commonly reported communication deficits among patients with acquired brain damage. Despite advances in the development of diagnostic tools for detecting such impairments, few studies have investigated interventions to rehabilitate patients presenting with these conditions. Objective: The aim of this study was to present a systematic review of the methods used in the rehabilitation of discourse following acquired brain injury. Methods: The PubMed database was searched for articles using the following keywords: "rehabilitation", "neurological injury", "communication" and "discursive abilities". Results: A total of 162 abstracts were found, but only seven of these met criteria for inclusion in the review. Four studies involved samples of individuals with aphasia whereas three studies recruited samples of individuals with traumatic brain injury. Conclusion: All but one article found that patient performance improved following participation in a discourse rehabilitation program.

    Full Text Available Inflammation is the key host-defense response to infection and injury, yet also a major contributor to a diverse range of diseases, both peripheral and central in origin. Brain injury as a result of stroke or trauma is a leading cause of death and disability worldwide, yet there are no effective treatments, resulting in enormous social and economic costs. Increasing evidence, both preclinical and clinical, highlights inflammation as an important factor in stroke, both in determining outcome and as a contributor to risk. A number of inflammatory mediators have been proposed as key targets for intervention to reduce the burden of stroke, several reaching clinical trial, but as yet yielding no success. Many factors could explain these failures, including the lack of robust preclinical evidence and poorly designed clinical trials, in addition to the complex nature of the clinical condition. Lack of consideration in preclinical studies of associated co-morbidities prevalent in the clinical stroke population is now seen as an important omission in previous work. These co-morbidities (atherosclerosis, hypertension, diabetes, infection have a strong inflammatory component, supporting the need for greater understanding of how inflammation contributes to acute brain injury. Interleukin (IL-1 is the prototypical pro-inflammatory cytokine, first identified many years ago as the endogenous pyrogen. Research over the last 20 years or so reveals that IL-1 is an important mediator of neuronal injury and blocking the actions of IL-1 is beneficial in a number of experimental models of brain damage. Mechanisms underlying the actions of IL-1 in brain injury remain unclear, though increasing evidence indicates the cerebrovasculature as a key target. Recent literature supporting this and other aspects of how IL-1 and systemic inflammation in general contribute to acute brain injury are discussed in this review.

    Stroke and other adult-acquired brain injury may impair perception leading to distress and increased dependence on others. Perceptual rehabilitation includes functional training, sensory stimulation, strategy training and task repetition. To examine the evidence for improvement in activities of daily living (ADL) six months post randomisation for active intervention versus placebo or no treatment. We searched the trials registers of the Cochrane Stroke Group and the Cochrane Infectious Diseases Group (May 2009) but not the Injuries Group, the Cochrane Central Register of Controlled Trials (The Cochrane Library 2009, Issue 3), MEDLINE (1950 to August 2009), EMBASE (1980 to August 2009), CINAHL (1982 to August 2009), PsycINFO (1974 to August 2009), REHABDATA and PsycBITE (May to June 2009). We also searched trials and research registers, handsearched journals, searched reference lists and contacted authors. Randomised controlled trials of adult stroke or acquired brain injury. Our definition of perception excluded visual field deficits, neglect/inattention and apraxia. One review author assessed titles, abstracts and keywords for eligibility. At least two review authors independently extracted data. We requested unclear or missing information from corresponding authors. We included six single-site trials in rehabilitation settings, involving 338 participants. Four trials included people with only stroke. All studies provided sensory stimulation, sometimes with another intervention. Sensory stimulation typically involved practising tasks that required visuo-perceptual processing with occupational therapist assistance. Repetition was never used and only one study included functional training. No trials provided data on longer term improvement in ADL scores. Only three trials provided any data suitable for analysis. Two of these trials compared active to placebo intervention. There was no evidence of a difference in ADL scores at the scheduled end of intervention: mean

    To outline differences in neurosurgical intervention (NI) rates between intracranial hemorrhage (ICH) types in mild traumatic brain injuries and help identify which ICH types are most likely to benefit from creation of predictive models for NI. A multicenter retrospective study of adult patients spanning 3 years at 4 U.S. trauma centers was performed. Patients were included if they presented with mild traumatic brain injury (Glasgow Coma Scale score 13-15) with head CT scan positive for ICH. Patients were excluded for skull fractures, "unspecified hemorrhage," or coagulopathy. Primary outcome was NI. Stepwise multivariable logistic regression models were built to analyze the independent association between ICH variables and outcome measures. The study comprised 1876 patients. NI rate was 6.7%. There was a significant difference in rate of NI by ICH type. Subdural hematomas had the highest rate of NI (15.5%) and accounted for 78% of all NIs. Isolated subarachnoid hemorrhages had the lowest, nonzero, NI rate (0.19%). Logistic regression models identified ICH type as the most influential independent variable when examining NI. A model predicting NI for isolated subarachnoid hemorrhages would require 26,928 patients, but a model predicting NI for isolated subdural hematomas would require only 328 patients. This study highlighted disparate NI rates among ICH types in patients with mild traumatic brain injury and identified mild, isolated subdural hematomas as most appropriate for construction of predictive NI models. Increased health care efficiency will be driven by accurate understanding of risk, which can come only from accurate predictive models. Copyright © 2017 Elsevier Inc. All rights reserved.

    Dysarthria is an acquired speech disorder following neurological injury that reduces intelligibility of speech due to weak, imprecise, slow and/or unco-ordinated muscle control. The impact of dysarthria goes beyond communication and affects psychosocial functioning. This is an update of a review previously published in 2005. The scope has been broadened to include additional interventions, and the title amended accordingly. To assess the effects of interventions to improve dysarthric speech following stroke and other non-progressive adult-acquired brain injury such as trauma, infection, tumour and surgery. We searched the Cochrane Stroke Group Trials Register (May 2016), CENTRAL (Cochrane Library 2016, Issue 4), MEDLINE, Embase, and CINAHL on 6 May 2016. We also searched Linguistics and Language Behavioral Abstracts (LLBA) (1976 to November 2016) and PsycINFO (1800 to September 2016). To identify further published, unpublished and ongoing trials, we searched major trials registers: WHO ICTRP, the ISRCTN registry, and ClinicalTrials.gov. We also handsearched the reference lists of relevant articles and contacted academic institutions and other researchers regarding other published, unpublished or ongoing trials. We did not impose any language restrictions. We selected randomised controlled trials (RCTs) comparing dysarthria interventions with 1) no intervention, 2) another intervention for dysarthria (this intervention may differ in methodology, timing of delivery, duration, frequency or theory), or 3) an attention control. Three review authors selected trials for inclusion, extracted data, and assessed risk of bias. We attempted to contact study authors for clarification and missing data as required. We calculated standardised mean difference (SMD) and 95% confidence interval (CI), using a random-effects model, and performed sensitivity analyses to assess the influence of methodological quality. We planned to conduct subgroup analyses for underlying clinical

    To determine whether successful participants along different postacute brain injury rehabilitation pathways differ on demographic, injury-related, disability, and outcome variables. Secondary analysis of pre- and posttreatment, and 1-year follow-up data obtained in a previous study of specialized vocational services (SVS) for persons with brain injury. Outpatient brain injury rehabilitation clinic. One hundred fourteen persons with acquired brain injury. Participants in 3 distinct rehabilitation pathways were studied: SVS only; SVS and a 3-h/wk community reintegration outpatient group; and SVS and 6-h/d comprehensive day treatment (CDT). Mayo-Portland Adaptability Inventory (MPAI); Vocational Independence Scale; and "success," as defined by community-based employment (CBE) at 1-year follow-up. The percentage (77%-85%) of participants in CBE at 1-year follow-up did not differ among the 3 pathways. CDT participants had more limited educational backgrounds, were less recently injured, and showed greater disability and more impaired self-awareness than those receiving limited intervention (ie, SVS or community reintegration outpatient group). MPAI scores for limited-intervention participants who were unsuccessful were similar in level to successful participants in CDT. Logistic regression models were developed to predict the probability of success with limited intervention and CDT. Different rehabilitation pathways result in CBE for a large percentage of persons with brain injury if the intensity of service is appropriately matched to the severity of the disability, the time since injury, and other participant characteristics.

    Structural connectivity analysis based on graph theory and diffusion tensor imaging tractography is a novel method that quantifies the topological characteristics in the brain network. This study aimed to examine structural connectivity changes following the Attention Intervention and Management (AIM) program designed to improve attention and executive function (EF) in children with traumatic brain injury (TBI). Seventeen children with complicated mild to severe TBI (13.66 ± 2.68 years; >12 months postinjury) completed magnetic resonance imaging (MRI) and neurobehavioral measures at time 1, 10 of whom completed AIM and assessment at time 2. Eleven matched healthy comparison (HC) children (13.37 ± 2.08 years) completed MRI and neurobehavioral assessment at both time points, but did not complete AIM. Network characteristics were analyzed to quantify the structural connectivity before and after the intervention. Mixed model analyses showed that small-worldness was significantly higher in the TBI group than the HC group at time 1, and both small-worldness and normalized clustering coefficient decreased significantly at time 2 in the TBI group whereas the HC group remained relatively unchanged. Reductions in mean local efficiency were significantly correlated with improvements in verbal inhibition and both parent- and child-reported EF. Increased normalized characteristic path length was significantly correlated with improved sustained attention. The results provide preliminary evidence suggesting that graph theoretical analysis may be a sensitive tool in pediatric TBI for detecting ( a) abnormalities of structural connectivity in brain network and ( b) structural neuroplasticity associated with neurobehavioral improvement following a short-term intervention for attention and EF.

    Abstract Traumatic brain injury leads to significant loss of brain volume, which continues into the chronic stage. This can be sensitively measured using volumetric analysis of MRI. Here we: (i) investigated longitudinal patterns of brain atrophy; (ii) tested whether atrophy is greatest in sulcal cortical regions; and (iii) showed how atrophy could be used to power intervention trials aimed at slowing neurodegeneration. In 61 patients with moderate-severe traumatic brain injury (mean age = 41.55 years ± 12.77) and 32 healthy controls (mean age = 34.22 years ± 10.29), cross-sectional and longitudinal (1-year follow-up) brain structure was assessed using voxel-based morphometry on T1-weighted scans. Longitudinal brain volume changes were characterized using a novel neuroimaging analysis pipeline that generates a Jacobian determinant metric, reflecting spatial warping between baseline and follow-up scans. Jacobian determinant values were summarized regionally and compared with clinical and neuropsychological measures. Patients with traumatic brain injury showed lower grey and white matter volume in multiple brain regions compared to controls at baseline. Atrophy over 1 year was pronounced following traumatic brain injury. Patients with traumatic brain injury lost a mean (± standard deviation) of 1.55% ± 2.19 of grey matter volume per year, 1.49% ± 2.20 of white matter volume or 1.51% ± 1.60 of whole brain volume. Healthy controls lost 0.55% ± 1.13 of grey matter volume and gained 0.26% ± 1.11 of white matter volume; equating to a 0.22% ± 0.83 reduction in whole brain volume. Atrophy was greatest in white matter, where the majority (84%) of regions were affected. This effect was independent of and substantially greater than that of ageing. Increased atrophy was also seen in cortical sulci compared to gyri. There was no relationship between atrophy and time since injury or age at baseline. Atrophy rates were related to memory performance at the end of the

    Latina teen pregnancy rates continue to be a health disparity in the United States. This study evaluated a parenting intervention using interactive theater to facilitate Latino parent-adolescent communication about sexuality and pregnancy prevention. The intervention, conducted in Spanish and with teen actors, consisted of scenes involving the audience. Fifty-nine parents participated in this 3-month prospective study. Spanish measures of comfort with communication, general communication, and parent-child sexual communication were employed comparing paired t tests for each scale. Acceptability of the intervention was assessed and demonstrated. Eighty-six percent of parents used information from the performance to talk to their child. Improvements in general communication (p < .02), sexual communication (p < .001), and comfort (p < .001) occurred. Interactive theater is an innovative approach to facilitate Latino parent communication about sexuality and pregnancy prevention.

  6. New Antioxidant Drugs for Neonatal Brain Injury

    Full Text Available The brain injury concept covers a lot of heterogeneity in terms of aetiology involving multiple factors, genetic, hemodynamic, metabolic, nutritional, endocrinological, toxic, and infectious mechanisms, acting in antenatal or postnatal period. Increased vulnerability of the immature brain to oxidative stress is documented because of the limited capacity of antioxidant enzymes and the high free radicals (FRs generation in rapidly growing tissue. FRs impair transmembrane enzyme Na+/K+-ATPase activity resulting in persistent membrane depolarization and excessive release of FR and excitatory aminoacid glutamate. Besides being neurotoxic, glutamate is also toxic to oligodendroglia, via FR effects. Neuronal cells die of oxidative stress. Excess of free iron and deficient iron/binding metabolising capacity are additional features favouring oxidative stress in newborn. Each step in the oxidative injury cascade has become a potential target for neuroprotective intervention. The administration of antioxidants for suspected or proven brain injury is still not accepted for clinical use due to uncertain beneficial effects when treatments are started after resuscitation of an asphyxiated newborn. The challenge for the future is the early identification of high-risk babies to target a safe and not toxic antioxidant therapy in combination with standard therapies to prevent brain injury and long-term neurodevelopmental impairment.

    Biological sex is an important determinant of stroke risk and outcome. Women are protected from cerebrovascular disease relative to men, an observation commonly attributed to the protective effect of female sex hormones, estrogen and progesterone. However, sex differences in brain injury persist well beyond the menopause and can be found in the pediatric population, suggesting that the effects of reproductive steroids may not completely explain sexual dimorphism in stroke. We review recent advances in our understanding of sex steroids (estradiol, progesterone and testosterone) in the context of ischemic cell death and neuroprotection. Understanding the molecular and cell-based mechanisms underlying sex differences in ischemic brain injury will lead to a better understanding of basic mechanisms of brain cell death and is an important step toward designing more effective therapeutic interventions in stroke.

    Inexperienced, less-skilled driving characterises many newly licensed drivers and contributes to high crash rates. A randomised trial of TeenDrivingPlan (TDP), a new learner driver phase internet-based intervention, demonstrated effectiveness in improving safety relevant, on-road driving behaviour, primarily through greater driving practice diversity. To inform future learner driver interventions, this analysis examined TDP use and its association with practice diversity. Posthoc analysis of data from teen/parent dyads (n=107), enrolled early in learner phase and assigned to treatment arm in randomised trial. Inserted software beacons captured TDP use data. Electronic surveys completed by parents and teens assessed diversity of practice driving and TDP usability ratings at 24 weeks (end of study period). Most families (84%) used TDP early in the learner period; however, the number of TDP sessions in the first week was three times higher among dyads who achieved greater practice diversity than those with less. By week five many families still engaged with TDP, but differences in TDP use could not be detected between families with high versus low practice diversity. Usability was not a major issue for this sample based on largely positive user ratings. An engaging internet-based intervention, such as TDP, can support families in achieving high practice diversity. Future learner driver interventions should provide important information early in the learner period when engagement is greatest, encourage continued learning as part of logging practice drives, and incorporate monitoring software for further personalisation to meet family needs.

    Examine a psychoeducational and skill-building intervention's effectiveness for individuals after traumatic brain injury (TBI), using a two-arm, parallel, randomized, controlled trial with wait-listed control. The Resilience and Adjustment Intervention (RAI) targets adjustment challenges and emphasizes education, skill-building and psychological support. Overall, 160 outpatients were randomly assigned to a treatment or wait-list control (WLC) group. The manualized treatment was delivered in seven 1-h sessions. The Connor-Davidson Resilience Scale (CD-RISC) was the primary outcome measure. Secondary measures included the Mayo Portland Adaptability Inventory-4 (MPAI-4), Brief Symptom Inventory-18 (BSI-18) and 13-Item Stress Test. After adjusting for injury severity, education and time postinjury, the RAI group (N = 75) demonstrated a significantly greater increase in resilience (effect size = 1.03) compared to the WLC group (N = 73). Participants in the RAI group demonstrated more favourable scores on the MPAI-4 Adjustment and Ability Indices, BSI-18 and the 13-item Stress Test. However, only the CD-RISC and BSI-18 demonstrated a clinically significant difference. In addition, RAI participants demonstrated maintenance of gains from pre-treatment to 3-month follow-up; however, only the BSI-18 maintained a clinically significant difference. Investigation provided evidence that a resilience-focused intervention can improve psychological health and adjustment after TBI. Additional research is needed to ascertain the longer term benefits of intervention and the efficacy of alternative delivery methods (e.g., via telephone, Internet).

    The purpose of this study was to determine nurses' perceptions about caring for patients with traumatic brain injury. Annually, it is estimated that over 10 million people sustain a traumatic brain injury around the world. Patients with traumatic brain injury and their families are often concerned with expectations about recovery and seek information from nurses. Nurses' perceptions of care might influence information provided to patients and families, particularly if inaccurate knowledge and perceptions are held. Thus, nurses must be knowledgeable about care of these patients. A cross-sectional survey, the Perceptions of Brain Injury Survey (PBIS), was completed electronically by 513 nurses between October and December 2014. Data were analysed with structural equation modelling, factor analysis, and pairwise comparisons. Using latent class analysis, authors were able to divide nurses into three homogeneous sub-groups based on perceived knowledge: low, moderate and high. Findings showed that nurses who care for patients with traumatic brain injury the most have the highest perceived confidence but the lowest perceived knowledge. Nurses also had significant variations in training. As there is limited literature on nurses' perceptions of caring for patients with traumatic brain injury, these findings have implications for training and educating nurses, including direction for development of nursing educational interventions. As the incidence of traumatic brain injury is growing, it is imperative that nurses be knowledgeable about care of patients with these injuries. The traumatic brain injury PBIS can be used to determine inaccurate perceptions about caring for patients with traumatic brain injury before educating and training nurses. © 2016 John Wiley & Sons Ltd.

    The Relational Neurobehavioral Approach (RNA) is a set of non-aversive intervention methods to manage individuals with brain injury-related aggression. New data on interventions used in the RNA and on how the RNA interventions can be used with patients with acquired brain injury (ABI) who have differing levels of functional impairment are provided in this paper. The study was conducted over a 6-week period in a secure 65-bed program for individuals with ABI that is housed in two units of a skilled nursing facility (SNF). Implementation of the RNA was compared between two units that housed patients with differing levels of functional impairment (n = 65 adults). Since this was a hierarchical clustered dataset, Generalized Estimating Equations regression was used in the analyses. RNA interventions used to manage the 495 aggressive incidents included the following: Aggression ignored, Closer observation, Talking to patient, Reassurance, Physical distraction, Isolation without seclusion, Immediate medication by mouth, Holding patient. Different interventions were implemented differentially by staff based on level of functional impairment and without use of seclusion or mechanical restraint. The RNA can be used to non-aversively manage aggression in patients with brain injury and with differing levels of functional impairment. Programs adopting the RNA can potentially manage brain injury-related aggression without seclusion or mechanical restraint. Implications for Rehabilitation The Relational Neurobehavioral Approach (RNA) is a set of non-aversive intervention methods to manage individuals with brain injury-related aggression. RNA methods can be used to manage aggression in patients with brain injury who have differing levels of functional impairment. Successful implementation of the RNA may allow for the management of brain injury-related aggression without seclusion or mechanical restraint.

    Impairments in attention and memory are common sequelae following paediatric acquired brain injury (ABI). While it has been established that such impairments are long-term and, therefore, affect quality-of-life, there is a scarcity of evidence-based interventions to treat these difficulties. The current study aimed to pilot the efficacy of the Amsterdam Memory and Attention Training for Children (Amat-c: English version) using both neuropsychological and ecologically sensitive measures. It was expected that children with attention and memory difficulties post-ABI would show improved performance post-intervention on cognitive and ecological measures, with maintenance at 6 months post-intervention. Ten children with an ABI, between the ages of 8-13 years at the time of recruitment were identified through audits of presentations to a metropolitan paediatric hospital. Each child underwent screening, the 18 week intervention programme, pre-intervention, immediate and 6 month post-intervention assessments. Findings supported the hypothesis that children would show post-intervention (immediate and 6 month) improvement in areas of attention and memory, with generalization to everyday life. Preliminary results provide support for the efficacy of the Amat-c post-childhood ABI. A larger study is needed to confirm these findings, as a reduction in attention and memory difficulties will enhance everyday functioning.

    To evaluate (1) the trajectory of resilience during the first year after a moderate-severe traumatic brain injury (TBI); (2) factors associated with resilience at 3, 6, and 12 months postinjury; and (3) changing relationships over time between resilience and other factors. Longitudinal analysis of an observational cohort. Five inpatient rehabilitation centers. Patients with TBI (N=195) enrolled in the resilience module of the TBI Model Systems study with data collected at 3-, 6-, and 12-month follow-up. Not applicable. Connor-Davidson Resilience Scale. Initially, resilience levels appeared to be stable during the first year postinjury. Individual growth curve models were used to examine resilience over time in relation to demographic, psychosocial, and injury characteristics. After adjusting for these characteristics, resilience actually declined over time. Higher levels of resilience were related to nonminority status, absence of preinjury substance abuse, lower anxiety and disability level, and greater life satisfaction. Resilience is a construct that is relevant to understanding brain injury outcomes and has potential value in planning clinical interventions.

Design Prospective, multicenter, longitudinal cohort study. Setting Acute TBI rehabilitation programs. Participants Patients (N=1946) receiving 138,555 therapy sessions. Interventions Not applicable. Main Outcome Measures Effort in rehabilitation sessions rated on the Rehabilitation Intensity of Therapy Scale, FIM, Comprehensive Severity Index brain injury severity score, posttraumatic amnesia (PTA), and Agitated Behavior Scale (ABS). Results The Rehabilitation Intensity of Therapy Scale effort ratings in individual therapy sessions closely conformed to a normative distribution for all 3 disciplines. Mean Rehabilitation Intensity of Therapy Scale ratings for patients' therapy sessions were higher in the discharge week than in the admission week (Prehabilitation, differences in effort ratings (Pcognitive scores and over time. In linear mixed-effects modeling, age and Comprehensive Severity Index brain injury severity score at admission, days from injury to rehabilitation admission, days from admission, and daily ratings of PTA and ABS score were predictors of level of effort (Prehabilitation setting using the Rehabilitation Intensity of Therapy Scale. Patients who sustain TBI show varying levels of effort in rehabilitation therapy sessions, with effort tending to increase over the stay. PTA and agitated behavior are primary risk factors that substantially reduce patient effort in therapies. PMID:26212400

    Full Text Available It is well established that the endothelium responds to mechanical forces induced by changes in shear stress and mechanotransduction. However, our understanding of vascular remodeling following traumatic brain injury (TBI remains incomplete. Recently published studies have revealed that lung and umbilical endothelial cells produce extracellular microvesicles (eMVs, such as microparticles, in response to changes in mechanical forces (blood flow and mechanical injury. Yet, to date, no studies have shown whether brain endothelial cells produce eMVs following TBI. The brain endothelium is highly specialized and forms the blood-brain barrier (BBB, which regulates diffusion and transport of solutes into the brain. This specialization is largely due to the presence of tight junction proteins (TJPs between neighboring endothelial cells. Following TBI, a breakdown in tight junction complexes at the BBB leads to increased permeability, which greatly contributes to the secondary phase of injury. We have therefore tested the hypothesis that brain endothelium responds to mechanical injury, by producing eMVs that contain brain endothelial proteins, specifically TJPs. In our study, primary human adult brain microvascular endothelial cells (BMVEC were subjected to rapid mechanical injury to simulate the abrupt endothelial disruption that can occur in the primary injury phase of TBI. eMVs were isolated from the media following injury at 2, 6, 24 and 48 hrs. Western blot analysis of eMVs demonstrated a time-dependent increase in TJP occludin, PECAM-1 and ICAM-1 following mechanical injury. In addition, activation of ARF6, a small GTPase linked to extracellular vesicle production, was increased after injury. To confirm these results in vivo, mice were subjected to sham surgery or TBI and blood plasma was collected 24 hrs post-injury. Isolation and analysis of eMVs from blood plasma using cryo-EM and flow cytometry revealed elevated levels of vesicles containing

    Teen drivers are at high risk for car crashes, especially during their first years of licensure. Providing novice teen drivers and their parents with a means of identifying their risky driving maneuvers may help them learn from their mistakes, thereby reducing their crash propensity. During the initial phase of learning, adult or parental supervision often provides such guidance. However, once teens obtain their license, adult supervision is no longer mandated, and teens are left to themselves to continue the learning process. This study is the first of its type to enhance this continued learning process using an event-triggered video device. By pairing this new technology with parental feedback in the form of a weekly video review and graphical report card, we extend parents' ability to teach their teens even after they begin driving independently. Twenty-six 16- to 17-year-old drivers were recruited from a small U.S. Midwestern rural high school. We equipped their vehicles with an event-triggered video device, designed to capture 20-sec clips of the forward and cabin views whenever the vehicle exceeded lateral or forward threshold accelerations. Preliminary findings suggest that combining this emerging technology with parental weekly review of safety-relevant incidents resulted in a significant decrease in events for the more at-risk teen drivers. Implications for how such an intervention could be implemented within GDL are also discussed.

    Since progressive hemorrhagic injury (PHI) was introduced in neurosurgical literatures, several studies have been performed, the results of which have influenced doctors but do not define guidelines for the best treatment of PHI. PHI may be confirmed by a serial computerized tomography (CT) scan, and it has been shown to be associated with a fivefold increase in the risk of clinical worsening and is a significant cause of morbidity and mortality as well. So, early detection of PHI is practically important in a clinical situation. To analyze the early CT signs of progressive hemorrhagic injury following acute traumatic brain injury (TBI) and explore their clinical significances, PHI was confirmed by comparing the first and repeated CT scans. Data were analyzed and compared including times from injury to the first CT and signs of the early CT scan. Logistic regression analysis was used to show the risk factors related to PHI. A cohort of 630 TBI patients was evaluated, and there were 189 (30%) patients who suffered from PHI. For patients with their first CT scan obtained as early as 2 h post-injury, there were 116 (77.25%) cases who suffered from PHI. The differences between PHIs and non-PHIs were significant in the initial CT scans showing fracture, subarachnoid hemorrhage (SAH), brain contusion, epidural hematoma (EDH), subdural hematoma (SDH), and multiple hematoma as well as the times from injury to the first CT scan (P < 0.01). Logistic regression analysis showed that early CT scans (EDH, SDH, SAH, fracture, and brain contusion) were predictors of PHI (P < 0.01). For patients with the first CT scan obtained as early as 2 h post-injury, a follow-up CT scan should be performed promptly. If the initial CT scan shows SAH, brain contusion, and primary hematoma with brain swelling, an earlier and dynamic CT scan should be performed for detection of PHI as early as possible and the medical intervention would be enforced in time.

    There are no clinically relevant treatments available that improve function in the growing population of very preterm infants (less than 32 weeks' gestation) with neonatal brain injury. Diffuse white matter injury (DWMI) is a common finding in these children and results in chronic neurodevelopmental impairments. As shown recently, failure in oligodendrocyte progenitor cell maturation contributes to DWMI. We demonstrated previously that the epidermal growth factor receptor (EGFR) has an important role in oligodendrocyte development. Here we examine whether enhanced EGFR signalling stimulates the endogenous response of EGFR-expressing progenitor cells during a critical period after brain injury, and promotes cellular and behavioural recovery in the developing brain. Using an established mouse model of very preterm brain injury, we demonstrate that selective overexpression of human EGFR in oligodendrocyte lineage cells or the administration of intranasal heparin-binding EGF immediately after injury decreases oligodendroglia death, enhances generation of new oligodendrocytes from progenitor cells and promotes functional recovery. Furthermore, these interventions diminish ultrastructural abnormalities and alleviate behavioural deficits on white-matter-specific paradigms. Inhibition of EGFR signalling with a molecularly targeted agent used for cancer therapy demonstrates that EGFR activation is an important contributor to oligodendrocyte regeneration and functional recovery after DWMI. Thus, our study provides direct evidence that targeting EGFR in oligodendrocyte progenitor cells at a specific time after injury is clinically feasible and potentially applicable to the treatment of premature children with white matter injury.

    2014-03-01

    The purpose of this study was to determine the effectiveness of contact versus education interventions for adolescents in reducing stigmatizing attitudes toward people with acquired brain injury (ABI), and whether visibility of ABI affects the intervention outcome. 408 students (age range = 14-17 years) from 13 schools in the Mid-West of Ireland were randomly allocated to one of the three interventions: Education only, Contact (Visible Disability), or Contact ("Invisible" Disability). Stigmatizing attitudes were measured before and after intervention. Results suggest that a Contact intervention was more effective in reducing stigmatizing attitudes in terms of social restrictiveness, benevolence, and community mental health beliefs than education alone. Visibility of ABI impacted the effectiveness of the contact intervention on Community Mental Health beliefs only. Contact with a person with ABI is thus more effective in promoting positive attitudes than ABI education alone, while the presence of visible impairment was not found to increase this intervention effect.

    Traumatic brain injury (TBI) is a major cause of death and disability in all age groups. Among TBI, penetrating traumatic brain injuries (PTBI) have the worst prognosis and represent the leading cause of TBI-related morbidity and death. However, there are no specific drugs/interventions due to unclear pathophysiology. To gain insights we looked at cerebral metabolism in a PTBI rat model: penetrating ballistic-like brain injury (PBBI). Early after injury, regional cerebral oxygen tension and consumption significantly decreased in the ipsilateral cortex in the PBBI group compared with the control group. At the same time point, glucose uptake was significantly reduced globally in the PBBI group compared with the control group. Examination of Fluorojade B-stained brain sections at 24 hours after PBBI revealed an incomplete overlap of metabolic impairment and neurodegeneration. As expected, the injury core had the most severe metabolic impairment and highest neurodegeneration. However, in the peri-lesional area, despite similar metabolic impairment, there was lesser neurodegeneration. Given our findings, the data suggest the presence of two distinct zones of primary injury, of which only one recovers. We anticipate the peri-lesional area encompassing the PBBI ischemic penumbra, could be salvaged by acute therapies. PMID:25669903

    2007-01-01

    Objective: To evaluate plasma arginine vasopressin (AVP) level in patients with traumatic brain injury and investigate the role of AVP in the process of brain edema. Methods: A total of 30 patients with traumatic brain injury were involved in our study. They were divided into two groups by Glasgow Coma Scale: severe traumatic brain injury group (STBI, GCS≤ 8) and moderate traumatic brain injury group (MTBI, GCS>8).Samples of venous blood were collected in the morning at rest from 15 healthy volunteers (control group)and within 24 h after traumatic brain injury from these patients for AVP determinations by radioimmunoassay. The severity and duration of the brain edema were estimated by head CT scan.Results: plasma AVP levels (ng/L) were (mean±SD): control, 3.06±1.49; MTBI, 38.12±7.25; and STBI, 66.61±17.10.The plasma level of AVP was significantly increased within 24 h after traumatic brain injury and followed by the reduction of GCS, suggesting the deterioration of cerebral injury (P<0.01). And the AVP level was correlated with the severity (STBI r=0.919, P<0.01; MTBI r=0.724, P<0.01) and the duration of brain edema (STBI r=0.790, P<0.01; MTBI r=0.712, P<0.01). Conclusions: The plasma AVP level is closely associated with the severity of traumatic brain injury. AVP may play an important role in pathogenesis of brain edema after traumatic brain injury.

  13. The Evidence for Brain Injury in Whiplash Injuries

    Directory of Open Access Journals (Sweden)

    Michael P. Alexander

    2003-01-01

    Full Text Available The evidence that brain damage can occur in injuries that produce whiplash is reviewed. The clinical phenomena for the two injuries are the same. Pure whiplash injury implies no, or minimal head contact, but many patients also have head contact against a head rest or the steering wheel or windshield. The relative severity of the neck injury and the head injury distinguishes whiplash from mild closed head injury. If there is brain injury is some patients with whiplash, it, by definition, falls at the mildest end of the concussion spectrum. The relationship between these two injuries is examined.

    Each year about 4,000 teens ages 16-19 die on U.S. roads. Injury prevention counseling is recommended as a valuable and cost-effective part of routine health supervision. This study describes pediatrician knowledge and practice regarding teen driving safety. A 31-item self-administered survey was mailed to pediatricians. 160 of 392 pediatricians (41%) completed the survey. During a health supervision visit 93% of pediatricians reported discussing seat belt use, 89% impaired driving, 54% teen licensing laws, and 16% parent teen contract. Half reported having a teen in their practice killed in a crash. A majority surveyed report discussing and counseling teens on first wave teen driver safety issues (seat belts, alcohol use), but most do not discuss graduated driver licensing laws or related issues. Broadly adopted, this inexpensive counseling approach, could lead to reductions in teen motorvehicle crash injuries.

    A functional analysis of behaviour was conducted to determine the controlling variables related to the perseverative verbal behaviour (PBV) of a 60-year-old female with a long-standing traumatic brain injury receiving educational assistance. Functional analyses (FA) of antecedent and consequent conditions related to PCB were conducted to determine controlling influence of: (a) content of verbal interaction and, (b) social reinforcement. After isolating the controlling variables, the functioned-based intervention was implemented in 60 minute tutoring sessions. A reversal condition was used to demonstrate experimental control of the behavior during tutoring sessions. PVB which occurred in the context of tutoring for an undergraduate course significantly interfered with the delivery of instruction. Multiple replications of the functional relation between social reinforcement and PVB duration was demonstrated using an A-B-A-B reversal design during functional analysis and tutoring conditions. PVB markedly declined, but did not extinguish over the course of weekly tutoring (extinction) sessions, most likely due to 'bootleg reinforcement' occurring in other situations. Results indicate that perseverative verbal behaviour following closed head injury may be strongly influenced by the social contingencies operating in various contexts and is amenable to applied behaviour analysis interventions.

    To perform a pilot study to evaluate whether a novel metacognitive, goal-based intervention improved and maintained the social communication skills of adults with traumatic brain injury (TBI). Eight community-dwelling participants with TBI completed three study phases: (1) baseline, (2) eight-week intervention targeting social communication impairments and (3) follow-up. Participants completed the Profile of Pragmatic Impairment in Communication (PPIC), LaTrobe Communication Questionnaire (LCQ) and Goal Attainment Scaling (GAS) at the commencement of baseline phase, pre- and post-intervention and completion of the follow-up phase. During the intervention programme phase, participants attended two 1-hour therapy sessions (one individual; one group) per week focusing on remediating impaired social communication skills using metacognitive strategy intervention and goal-based therapy. Variable changes in PPIC feature-summary scores were observed post-intervention. A non-significant improvement in LCQ scores was also observed. There was a significant increase in GAS goal T-scores following the intervention, with six of the eight participants achieving or exceeding their expected level of performance on all goals. A goal-driven, metacognitive approach to intervention may assist individuals with TBI to achieve their personal social communication goals, with benefits reported by participants and observable during conversations. Further research is required.

    Sport-related traumatic brain injuries are a significant public health burden, with hundreds of thousands sustained annually in North America. While sports offer numerous physical and social health benefits, traumatic brain injuries such as concussion can seriously impact a player's life, athletic career, and sport enjoyment. The culture in many sports encourages winning at all costs, placing athletes at risk for traumatic brain injuries. As social media has become a central part of everyday life, the content of users' messages often reflects the prevailing culture related to a particular event or health issue. We hypothesized that Twitter data might be useful for understanding public perceptions and misperceptions of sport-related traumatic brain injuries. We performed a content and sentiment analysis of 7483 Twitter ® tweets related to traumatic brain injuries in sports collected during June and July 2013. We identified five major themes. Users tweeted about personal traumatic brain injuries experiences, reported traumatic brain injuries in professional athletes, shared research about sport-related concussions, and discussed policy and safety in injury prevention, such as helmet use. We identified mixed perceptions of and sentiment toward traumatic brain injuries in sports: both an understanding that brain injuries are serious and disregard for activities that might reduce the public burden of traumatic brain injuries were prevalent in our Twitter analysis. While the scientific and medical community considers a concussion a form of traumatic brain injuries, our study demonstrates a misunderstanding of this fact among the public. In our current digital age, social media can provide useful insight into the culture around a health issue, facilitating implementation of prevention and treatment strategies.

    Teens' crash risk is highest in the first years of independent driving. Circumstances surrounding fatal crashes have been widely documented, but less is known about factors related to nonfatal teen driver crashes. This study describes single vehicle nonfatal crashes involving the youngest teen drivers (15-17 years), compares these crashes to single vehicle nonfatal crashes among adult drivers (35-44 years) and examines factors related to nonfatal injury producing crashes for teen drivers. Police crash data linked to hospital inpatient and emergency department data for 2005-2008 from the South Carolina Crash Outcomes Data Evaluation System (CODES) were analyzed. Nonfatal, single vehicle crashes involving passenger vehicles occurring on public roadways for teen (15-17 years) drivers were compared with those for adult (35-44 years) drivers on temporal patterns and crash risk factors per licensed driver and per vehicle miles traveled. Vehicle miles traveled by age group was estimated using data from the 2009 National Household Travel Survey. Multivariable log-linear regression analysis was conducted for teen driver crashes to determine which characteristics were related to crashes resulting in a minor/moderate injury or serious injury to at least one vehicle occupant. Compared with adult drivers, teen drivers in South Carolina had 2.5 times the single vehicle nonfatal crash rate per licensed driver and 11 times the rate per vehicle mile traveled. Teen drivers were nearly twice as likely to be speeding at the time of the crash compared with adult drivers. Teen driver crashes per licensed driver were highest during the afternoon hours of 3:00-5:59 pm and crashes per mile driven were highest during the nighttime hours of 9:00-11:59 pm. In 66% of the teen driver crashes, the driver was the only occupant. Crashes were twice as likely to result in serious injury when teen passengers were present than when the teen driver was alone. When teen drivers crashed while

    Traumatic cerebral vascular injury (TCVI) is a very frequent, if not universal, feature after traumatic brain injury (TBI). It is likely responsible, at least in part, for functional deficits and TBI-related chronic disability. Because there are multiple pharmacologic and non-pharmacologic therapies that promote vascular health, TCVI is an attractive target for therapeutic intervention after TBI. The cerebral microvasculature is a component of the neurovascular unit (NVU) coupling neuronal metabolism with local cerebral blood flow. The NVU participates in the pathogenesis of TBI, either directly from physical trauma or as part of the cascade of secondary injury that occurs after TBI. Pathologically, there is extensive cerebral microvascular injury in humans and experimental animal, identified with either conventional light microscopy or ultrastructural examination. It is seen in acute and chronic TBI, and even described in chronic traumatic encephalopathy (CTE). Non-invasive, physiologic measures of cerebral microvascular function show dysfunction after TBI in humans and experimental animal models of TBI. These include imaging sequences (MRI-ASL), Transcranial Doppler (TCD), and Near InfraRed Spectroscopy (NIRS). Understanding the pathophysiology of TCVI, a relatively under-studied component of TBI, has promise for the development of novel therapies for TBI. Published by Elsevier Inc.

    This study evaluated a computer-based prompting intervention for improving expository essay writing after acquired brain injury (ABI). Four undergraduate participants aged 18-21 with mild-moderate ABI and impaired fluid cognition at least 6 months post-injury reported difficulty with the writing process after injury. The study employed a non-concurrent multiple probe across participants, in a single-case design. Outcome measures included essay quality scores and number of revisions to writing counted then coded by type using a revision taxonomy. An inter-scorer agreement procedure was completed for quality scores for 50% of essays, with data indicating that agreement exceeded a goal of 85%. Visual analysis of results showed increased essay quality for all participants in intervention phase compared with baseline, maintained 1 week after. Statistical analyses showed statistically significant results for two of the four participants. The authors discuss external cuing for self-monitoring and tapping of existing writing knowledge as possible explanations for improvement. The study provides preliminary evidence that computer-based prompting has potential to improve writing quality for undergraduates with ABI.

    Objective: To study the clinical value of SPECT brain perfusion imaging after mild traumatic brain injury and to evaluate the mechanism of brain blood flow changes in the brain traumatic symptoms. Methods: SPECT 99 Tc m -ethylene cysteinate dimer (ECD) brain perfusion imaging was performed on 39 patients with normal consciousness and normal computed tomography. The study was performed on 23 patients within 3 months after the accidental injury and on 16 patients at more than 3 months post-injury. The cerebellum was used as the reference site (100% maximum value). Any decrease in cerebral perfusion in cortex or basal ganglia to below 70%, or even to below 50% in the medial temporal lobe, compared to the cerebellar reference was considered abnormal. Results: The results of 23 patients (59%) were abnormal. Among them, 20 patients showed 74 focal lesions with an average of 3.7 per patient (15 studies performed within 3 months and 8 studies performed more than 3 months after injury). The remaining 3 showed diffuse hypoperfusion (two at the early stage and one at more than 3 months after the injury). The 13 abnormal studies performed at the early stage showed 58 lesions (average, 4.5 per patient), whereas there was a reduction to an average of 2.3 per patient in the 7 patients (total 16 lesions) at more than 3 months post-injury. In the 20 patients with focal lesions, mainly the following regions were involved: frontal lobes 43.2% (32/74), basal ganglia 24.3% (18/74) and temporal lobes 17.6% (13/74). Conclusions: 1) SPECT brain perfusion imaging is more sensitive than computed tomography in detecting brain lesions of mild traumatic brain injury. 2) SPECT brain perfusion imaging is more sensitive at early stage than at late stage after injury. 3) The most common complaints were headache, dizziness, memory deficit. The patients without loss of consciousness may present brain hypoperfusion, too. 4) The changes may explain a neurological component of the patient symptoms in

    To explore feasibility and potential efficacy of on-line interventions for sleep quality following a traumatic brain injury (TBI). A two parallel-group, randomized controlled pilot study. Community-based. In all, 24 participants (mean age: 35.9 ± 11.8 years) who reported experiencing sleep difficulties between 3 and 36 months after a mild or moderate TBI. Participants were randomized to receive either a cognitive behaviour therapy or an education intervention on-line. Both interventions were self-completed for 20-30 minutes per week over a six-week period. The Pittsburgh Sleep Quality Index assessed self-reported sleep quality with actigraphy used as an objective measure of sleep quality. The CNS Vital Signs on-line neuropsychological test assessed cognitive functioning and the Rivermead Post-concussion Symptoms and Quality of Life after Brain Injury questionnaires were completed pre and post intervention. Both programmes demonstrated feasibility for use post TBI, with 83.3% of participants completing the interventions. The cognitive behaviour therapy group experienced significant reductions ( F = 5.47, p = 0.04) in sleep disturbance (mean individual change = -4.00) in comparison to controls post intervention (mean individual change = -1.50) with a moderate effect size of 1.17. There were no significant group differences on objective sleep quality, cognitive functioning, post-concussion symptoms or quality of life. On-line programmes designed to improve sleep are feasible for use for adults following mild-to-moderate TBI. Based on the effect size identified in this pilot study, 128 people (64 per group) would be needed to determine clinical effectiveness.

    Full Text Available Parental knowledge gained from monitoring activities protects against adolescent risk involvement. Parental monitoring approaches are varied and may be modified with successful interventions but not all parents or adolescents respond to monitoring programs the same way. 339 parent-adolescent dyads randomized to receive a parental monitoring intervention and 169 parent-adolescent dyads in the control group were followed for one year over four measurement periods. Parent attitudes about the usefulness of monitoring, the importance of trust and respecting their teens’ privacy, and the appropriateness of adolescent risk-taking behavior and experimentation were examined as predictors of longitudinal change in parental monitoring and open communication. Similar effects were found in both the intervention and control group models regarding open communication. Parental attitudes impacted longitudinal patterns of teen-reported parent monitoring, and these patterns differed across experimental groups. In the intervention group, parents’ beliefs about the importance of trust and privacy were associated with a steeper decline in monitoring across time. Finally, parents’ attitudes about the normative nature of teen experimentation were associated with a quadratic parental monitoring time trend in the intervention but not the control group. These findings suggest that parental attitudes may impact how families respond to an adolescent risk intervention.

    Full Text Available Injury to the fragile immature brain is implicated in the manifestation of long-term neurological disorders, including childhood disability such as cerebral palsy, learning disability and behavioral disorders. Advancements in perinatal practice and improved care mean the majority of infants suffering from perinatal brain injury will survive, with many subtle clinical symptoms going undiagnosed until later in life. Hypoxic-ischemia is the dominant cause of perinatal brain injury, and constitutes a significant socioeconomic burden to both developed and developing countries. Therapeutic hypothermia is the sole validated clinical intervention to perinatal asphyxia; however it is not always neuroprotective and its utility is limited to developed countries. There is an urgent need to better understand the molecular pathways underlying hypoxic-ischemic injury to identify new therapeutic targets in such a small but critical therapeutic window. Mitochondria are highly implicated following ischemic injury due to their roles as the powerhouse and main energy generators of the cell, as well as cell death processes. While the link between impaired mitochondrial bioenergetics and secondary energy failure following loss of high-energy phosphates is well established after hypoxia-ischemia (HI, there is emerging evidence that the roles of mitochondria in disease extend far beyond this. Indeed, mitochondrial turnover, including processes such as mitochondrial biogenesis, fusion, fission and mitophagy, affect recovery of neurons after injury and mitochondria are involved in the regulation of the innate immune response to inflammation. This review article will explore these mitochondrial pathways, and finally will summarize past and current efforts in targeting these pathways after hypoxic-ischemic injury, as a means of identifying new avenues for clinical intervention.

    Despite recent declines, teen unintended pregnancy and sexually transmitted infections in the United States remain at levels higher than comparable nations. Initiatives to prevent teen pregnancy have focused primarily on female adolescents; how to effectively engage young men to reduce their risk of fathering a teen pregnancy has not been well studied. We proposed to adapt an innovative computer-assisted motivational interviewing (CAMI) intervention, originally designed and tested with young women, for use with young men, aged 15-24 years, to reduce their risk of fathering a teen pregnancy. This manuscript describes the design of a CAMI intervention for young men aimed at preventing teen pregnancy and improving fitness. This randomized controlled trial will recruit 945 sexually active young men between the ages of 15 and 24 years from three health centers in New York City. Participants will be assigned by permuted block randomization to two study arms: one aimed at reducing involvement in unintended teen pregnancy (CAMI-teen pregnancy prevention) and the other at improving overall fitness (CAMI-Fitness). Except for topic, both intervention arms will provide four sessions of Motivational Interviewing coaching and use a mobile app to track behavior and set goals. We will assess young men's sexual and reproductive health behaviors and fitness at baseline, 12, 24, 36, and 64 weeks using a mobile device app created for the study. Pending ongoing study. Results from the study are expected to enhance our understanding of the efficacy of CAMI to enhance young men's reproductive health and fitness behaviors.

    To evaluate the effectiveness of simulation as a strategy to influence teens' perceptions of pregnancy and parenting. This pilot study was a preexperimental, one group pre/posttest design. The school-based wellness center of a high school was the setting for the weekly sessions and the pre/posttest administration. Sample members participated in 6 weekly Baby Think it Over (BTIO) classes and an infant simulator experience. The final sample included 79 teens age 14 to 18 years who attended one of eight BTIO sessions. We used the Thoughts on Teen Parenting Survey (TTPS) to assess the perceptions of teens with regard to the costs and rewards associated with teen parenting. The TTPS yields a composite score of the teen attitudes toward the teen parenting experience and eight subscale scores that assess different areas of teen life. No significant differences were found in the mean pre/posttest scores or in correlations of the demographic data and mean scores. Two significant differences in pre/posttest subscale scores were in the areas of friends and personal characteristics. The results of this study suggest that the effectiveness of using infant simulators to influence the perceptions of teens about the reality of teen parenting is minimal. © 2011 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

    Sleep problems affect 30% to 80% of patients with mild traumatic brain injury. We assessed the prevalence of sleep disorders after mild traumatic brain injury and its correlation with other symptoms. Individuals with mild traumatic brain injury were assessed at the New York University Concussion Center during 2013-2014 with the Sports Concussion Assessment Tool, third edition, data following mild traumatic brain injury. The relationship between sleep problems (drowsiness, difficulty falling asleep, fatigue or low energy), psychiatric symptoms (sadness, nervousness or anxiousness), headache, and dizziness were analyzed by Spearman correlation and logistic regression using moderate to severe versus none to mild categorization. Ninety-three patients were retrospectively considered. The most common injury causes were falls (34.4%) and motor vehicle accidents (21.5%). There was a positive correlation between dizziness, headache, psychiatric problems (sadness, anxiety, irritability), and sleep problems (fatigue, drowsiness, and difficulty falling asleep) (P sleep symptoms (P Sleep symptoms became more severe with increased time interval from mild traumatic brain injury to Sport Concussion Assessment Tool 3 administration (odds ratio = 1.005, 1.006, and 1.008, P sleep disorders following mild traumatic brain injury and should be counseled and initiated with early interventions.

    Full Text Available Cognitive deficits following traumatic brain injury (TBI commonly include difficulties with memory, attention, and executive dysfunction. These deficits are amenable to cognitive rehabilitation, but optimally selecting rehabilitation programs for individual patients remains a challenge. Recent methods for quantifying regional brain morphometry allow for automated quantification of tissue volumes in numerous distinct brain structures. We hypothesized that such quantitative structural information could help identify individuals more or less likely to benefit from memory rehabilitation. Fifty individuals with TBI of all severities who reported having memory difficulties first underwent structural MRI scanning. They then participated in a 12 session memory rehabilitation program emphasizing internal memory strategies (I-MEMS. Primary outcome measures (HVLT, RBMT were collected at the time of the MRI scan, immediately following therapy, and again at one month post-therapy. Regional brain volumes were used to predict outcome, adjusting for standard predictors (e.g., injury severity, age, education, pretest scores. We identified several brain regions that provided significant predictions of rehabilitation outcome, including the volume of the hippocampus, the lateral prefrontal cortex, the thalamus, and several subregions of the cingulate cortex. The prediction range of regional brain volumes were in some cases nearly equal in magnitude to prediction ranges provided by pretest scores on the outcome variable. We conclude that specific cerebral networks including these regions may contribute to learning during I-MEMS rehabilitation, and suggest that morphometric measures may provide substantial predictive value for rehabilitation outcome in other cognitive interventions as well.

    For typically developing infants, the last trimester of fetal development extending into the first post-natal months is a period of rapid brain development. Infants who are born premature face significant risk of brain injury (e.g., intraventricular or germinal matrix hemorrhage and periventricular leukomalacia) from complications in the perinatal period and also potential long-term neurodevelopmental disabilities because these early injuries can interrupt normal brain maturation. Neuroimaging has played an important role in the diagnosis and management of the preterm infant. Both cranial US and conventional MRI techniques are useful in diagnostic and prognostic evaluation of preterm brain development and injury. Cranial US is highly sensitive for intraventricular hemorrhage (IVH) and provides prognostic information regarding cerebral palsy. Data are limited regarding the utility of MRI as a routine screening instrument for brain injury for all preterm infants. However, MRI might provide diagnostic or prognostic information regarding PVL and other types of preterm brain injury in the setting of specific clinical indications and risk factors. Further development of advanced MR techniques like volumetric MR imaging, diffusion tensor imaging, metabolic imaging (MR spectroscopy) and functional connectivity are necessary to provide additional insight into the molecular, cellular and systems processes that underlie brain development and outcome in the preterm infant. The adult concept of the ''connectome'' is also relevant in understanding brain networks that underlie the preterm brain. Knowledge of the preterm connectome will provide a framework for understanding preterm brain function and dysfunction, and potentially even a roadmap for brain plasticity. By combining conventional imaging techniques with more advanced techniques, neuroimaging findings will likely be used not only as diagnostic and prognostic tools, but also as biomarkers for long

    Helmets are used for sports, military, and transportation to protect against impact forces and associated injuries. The common belief among end users is that the helmet protects the whole head, including the brain. However, current consensus among biomechanists and sports neurologists indicates that helmets do not provide significant protection against concussion and brain injuries. In this paper the authors present existing scientific evidence on the mechanisms underlying traumatic head and brain injuries, along with a biomechanical evaluation of 21 current and retired football helmets. The National Operating Committee on Standards for Athletic Equipment (NOCSAE) standard test apparatus was modified and validated for impact testing of protective headwear to include the measurement of both linear and angular kinematics. From a drop height of 2.0 m onto a flat steel anvil, each football helmet was impacted 5 times in the occipital area. Skull fracture risk was determined for each of the current varsity football helmets by calculating the percentage reduction in linear acceleration relative to a 140-g skull fracture threshold. Risk of subdural hematoma was determined by calculating the percentage reduction in angular acceleration relative to the bridging vein failure threshold, computed as a function of impact duration. Ranking the helmets according to their performance under these criteria, the authors determined that the Schutt Vengeance performed the best overall. The study findings demonstrated that not all football helmets provide equal or adequate protection against either focal head injuries or traumatic brain injuries. In fact, some of the most popular helmets on the field ranked among the worst. While protection is improving, none of the current or retired varsity football helmets can provide absolute protection against brain injuries, including concussions and subdural hematomas. To maximize protection against head and brain injuries for football players of

    Adolescent traumatic brain injury (TBI) contributes to deficits in executive functioning and behavior, but few evidence-based treatments exist. We conducted a randomized clinical trial comparing Teen Online Problem Solving with Family (TOPS-Family) with Teen Online Problem Solving with Teen Only (TOPS-TO) or the access to Internet Resources Comparison (IRC) group. Children, aged 11 to 18 years, who sustained a complicated mild-to-severe TBI in the previous 18 months were randomly assigned to the TOPS-Family (49), TOPS-TO (51), or IRC group (52). Parent and self-report measures of externalizing behaviors and executive functioning were completed before treatment and 6 months later. Treatment effects were examined using linear regression models, adjusting for baseline symptom levels. Age, maternal education, and family stresses were examined as moderators. The TOPS-Family group had lower levels of parent-reported executive dysfunction at follow-up than the TOPS-TO group, and differences between the TOPS-Family and IRC groups approached significance. Maternal education moderated improvements in parent-reported externalizing behaviors, with less educated parents in the TOPS-Family group reporting fewer symptoms. On the self-report Behavior Rating Inventory of Executive Functions, treatment efficacy varied with the level of parental stresses. The TOPS-Family group reported greater improvements at low stress levels, whereas the TOPS-TO group reported greater improvement at high-stress levels. The TOPS-TO group did not have significantly lower symptoms than the IRC group on any comparison. Findings support the efficacy of online family problem solving to address executive dysfunction and improve externalizing behaviors among youth with TBI from less advantaged households. Treatment with the teen alone may be indicated in high-stress families.

    Evidence from systematic reviews demonstrates that multi-disciplinary rehabilitation is effective in the stroke population, in which older adults predominate. However, the evidence base for the effectiveness of rehabilitation following acquired brain injury (ABI) in younger adults has not been established, perhaps because this scenario presents different methodological challenges in research. To assess the effects of multi-disciplinary rehabilitation following ABI in adults 16 to 65 years of age. We ran the most recent search on 14 September 2015. We searched the Cochrane Injuries Group Specialised Register, The Cochrane Library, Ovid MEDLINE(R), Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) Daily and Ovid OLDMEDLINE(R), Embase Classic+Embase (OvidSP), Web of Science (ISI WOS) databases, clinical trials registers, and we screened reference lists. Randomised controlled trials (RCTs) comparing multi-disciplinary rehabilitation versus routinely available local services or lower levels of intervention; or trials comparing an intervention in different settings, of different intensities or of different timing of onset. Controlled clinical trials were included, provided they met pre-defined methodological criteria. Three review authors independently selected trials and rated their methodological quality. A fourth review author would have arbitrated if consensus could not be reached by discussion, but in fact, this did not occur. As in previous versions of this review, we used the method described by Van Tulder 1997 to rate the quality of trials and to perform a 'best evidence' synthesis by attributing levels of evidence on the basis of methodological quality. Risk of bias assessments were performed in parallel using standard Cochrane methodology. However, the Van Tulder system provided a more discriminative evaluation of rehabilitation trials, so we have continued to use it for our primary synthesis of evidence. We subdivided trials in terms of

    To investigate the variables associated with positive psychological outcome following a group intervention for 33 individuals with traumatic brain injury. Evaluation study which used multiple regression analysis to examine the variables associated with change in psychological adjustment following a 10-session cognitive behaviour therapy-based group. The predictor variables were age at injury, time since injury, injury severity, self-awareness, pre-morbid intellectual function, memory function, executive function and level of depression and anxiety prior to intervention. The predictor variables contributed a significant proportion of the variance in percentage change in depression. The major finding was that better outcomes following intervention were associated with greater self-awareness of injury-related deficits. The present study identified a number of variables that were associated with improvement in depression following psychological intervention and may assist future treatment resources to be directed most effectively.

    To define the nature and frequency of brain injury and brain growth impairment in very preterm (VPT) infants by using MRI at term-equivalent age and to relate these findings to perinatal risk factors and 2-year neurodevelopmental outcomes. MRI scans at term-equivalent age from 3 VPT cohorts (n = 325) were reviewed. The severity of brain injury, including periventricular leukomalacia and intraventricular and cerebellar hemorrhage, was graded. Brain growth was assessed by using measures of biparietal width (BPW) and interhemispheric distance. Neurodevelopmental outcome at age 2 years was assessed across all cohorts (n = 297) by using the Bayley Scales of Infant Development, Second Edition (BSID-II) or Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III), and evaluation for cerebral palsy. Of 325 infants, 107 (33%) had some grade of brain injury and 33 (10%) had severe injury. Severe brain injury was more common in infants with lower Apgar scores, necrotizing enterocolitis, inotropic support, and patent ductus arteriosus. Severe brain injury was associated with delayed cognitive and motor development and cerebral palsy. Decreased BPW was related to lower gestational age, inotropic support, patent ductus arteriosus, necrotizing enterocolitis, prolonged parenteral nutrition, and oxygen at 36 weeks and was associated with delayed cognitive development. In contrast, increased interhemispheric distance was related to male gender, dexamethasone use, and severe brain injury. It was also associated with reduced cognitive development, independent of BPW. At term-equivalent age, VPT infants showed both brain injury and impaired brain growth on MRI. Severe brain injury and impaired brain growth patterns were independently associated with perinatal risk factors and delayed cognitive development.

    Data was analyzed relating to a consecutive series of 16 patients of penetrating brain injuries received at forward defense lines. Characteristics studied were the cause of injury, level of consciousness and various neurological deficits presented on initial examination, CT scan findings, the surgical procedures performed and the final outcome after one year of follow-up. One out of 16 patients, died due to severe associated injuries to abdominal viscera and major vessels. Meningitis occurred in one patient during the immediate postoperative period. All patients with motor weakness speech deficits and incontinence showed significant improvement. Hearing loss of one ear persisted in one patient. Two patients developed delayed onset seizures. It is concluded that, patients with penetrating brain injuries should be evacuated to the tertiary care neurosurgical centres as soon as possible. In operation only obviously necrotic brain and easily accessible metal and bone pieces should be removed. There is no need to explore the normal brain as it would only result in increased neurological deficits. The patients with such injuries should receive broad-spectrum antibiotics to prevent the infective complications. (author)

    2017-08-01

    For a long time, radiation-induced skin injuries were only encountered in patients undergoing radiation therapy. In diagnostic radiology, radiation exposures of patients causing skin injuries were extremely rare. The introduction of fast multislice CT scanners and fluoroscopically guided interventions (FGI) changed the situation. Both methods carry the risk of excessive high doses to the skin of patients resulting in skin injuries. In the early nineties, several reports of epilation and skin injuries following CT brain perfusion studies were published. During the same time, several papers reported skin injuries following FGI, especially after percutaneous coronary interventions and neuroembolisations. Thus, CT and FGI are of major concern regarding radiation safety since both methods can apply doses to patients exceeding 5 Gy (National Council on Radiation Protection and Measurements threshold for substantial radiation dose level). This paper reviews the problem of skin injuries observed after FGI. Also, some practical advices are given how to effectively avoid skin injuries. In addition, guidelines are discussed how to deal with patients who were exposed to a potentially dangerous radiation skin dose during medically justified interventional procedures.

  7. Hypopituitarism after acute brain injury.

    Acute brain injury has many causes, but the most common is trauma. There are 1.5-2.0 million traumatic brain injuries (TBI) in the United States yearly, with an associated cost exceeding 10 billion dollars. TBI is the most common cause of death and disability in young adults less than 35 years of age. The consequences of TBI can be severe, including disability in motor function, speech, cognition, and psychosocial and emotional skills. Recently, clinical studies have documented the occurrence of pituitary dysfunction after TBI and another cause of acute brain injury, subarachnoid hemorrhage (SAH). These studies have consistently demonstrated a 30-40% occurrence of pituitary dysfunction involving at least one anterior pituitary hormone following a moderate to severe TBI or SAH. Growth hormone (GH) deficiency is the most common pituitary hormone disorder, occurring in approximately 20% of patients when multiple tests of GH deficiency are used. Within 7-21 days of acute brain injury, adrenal insufficiency is the primary concern. Pituitary function can fluctuate over the first year after TBI, but it is well established by 1 year. Studies are ongoing to assess the effects of hormone replacement on motor function and cognition in TBI patients. Any subject with a moderate to severe acute brain injury should be screened for pituitary dysfunction.

    OBJECTIVE Severe traumatic brain injury remains a leading cause of morbidity and mortality in the pediatric population. Providers focus on reducing secondary brain injury by avoiding hypoxemia, avoiding hypotension, providing normoventilation, treating intracranial hypertension, and reducing cerebral metabolic demand. Hyperthermia is frequently present in patients with severe traumatic brain injury, contributes to cerebral metabolic demand, and is associated with prolonged hospital admission as well as impaired neurological outcome. The objective of this quality improvement initiative was to reduce the duration of hyperthermia for pediatric patients with severe traumatic brain injury during the initial 72 hours of admission to the pediatric intensive care unit. METHODS A retrospective chart review was performed to evaluate the incidence and duration of hyperthermia within a preintervention cohort. The retrospective phase was followed by three 6-month intervention periods (intervention Phase 1, the maintenance phase, and intervention Phase 2). Intervention Phase 1 entailed placement of a cooling blanket on the bed prior to patient arrival and turning it on once the patient's temperature rose above normothermia. The maintenance phase focused on sustaining the results of Phase 1. Intervention Phase 2 focused on total prevention of hyperthermia by initiating cooling blanket use immediately upon patient arrival to the intensive care unit. RESULTS The median hyperthermia duration in the preintervention cohort (n = 47) was 135 minutes. This was reduced in the Phase 1 cohort (n = 9) to 45 minutes, increased in the maintenance phase cohort (n = 6) to 88.5 minutes, and decreased again in the Phase 2 cohort (n = 9) to a median value of 0 minutes. Eight percent of patients in the intervention cohorts required additional sedation to tolerate the cooling blanket. Eight percent of patients in the intervention cohorts became briefly hypothermic while on the cooling blanket. No

    2014-10-01

    To provide clinicians with a review of recent research and clinically applicable tools regarding teen pregnancy. Teen pregnancy rates have declined but still remain a significant problem in the USA. Teen pregnancy prevention was identified by Centers for Disease Control and Prevention as one of its top six priorities, which is increasing research and intervention data. Long-acting contraceptive methods are acceptable to teens and have been shown to reduce teen birth rates. Pregnant teens need special attention to counseling on pregnancy options and reducing risk during pregnancy with regular prenatal care. Postpartum teens should be encouraged and supported to breastfeed, monitored for depression, and have access to reliable contraception to avoid repeat undesired pregnancy. This review highlights important issues for all providers caring for female adolescents and those who may encounter teen pregnancy. Foremost prevention of teen pregnancy by comprehensive sexual education and access to contraception is the priority. Educating patients and healthcare providers about safety and efficacy of long-acting reversible contraception is a good step to reducing undesired teen pregnancies. Rates of postpartum depression are greater in adolescents than in adults, and adolescent mothers need to be screened and monitored for depression. Strategies to avoid another undesired pregnancy shortly after delivery should be implemented.

    Rotational motion of the head as a mechanism for brain injury was proposed back in the 1940s. Since then a multitude of research studies by various institutions were conducted to confirm/reject this hypothesis. Most of the studies were conducted on animals and concluded that rotational kinematics experienced by the animal's head may cause axonal deformations large enough to induce their functional deficit. Other studies utilized physical and mathematical models of human and animal heads to derive brain injury criteria based on deformation/pressure histories computed from their models. This study differs from the previous research in the following ways: first, it uses two different detailed mathematical models of human head (SIMon and GHBMC), each validated against various human brain response datasets; then establishes physical (strain and stress based) injury criteria for various types of brain injury based on scaled animal injury data; and finally, uses Anthropomorphic Test Devices (ATDs) (Hybrid III 50th Male, Hybrid III 5th Female, THOR 50th Male, ES-2re, SID-IIs, WorldSID 50th Male, and WorldSID 5th Female) test data (NCAP, pendulum, and frontal offset tests) to establish a kinematically based brain injury criterion (BrIC) for all ATDs. Similar procedures were applied to college football data where thousands of head impacts were recorded using a six degrees of freedom (6 DOF) instrumented helmet system. Since animal injury data used in derivation of BrIC were predominantly for diffuse axonal injury (DAI) type, which is currently an AIS 4+ injury, cumulative strain damage measure (CSDM) and maximum principal strain (MPS) were used to derive risk curves for AIS 4+ anatomic brain injuries. The AIS 1+, 2+, 3+, and 5+ risk curves for CSDM and MPS were then computed using the ratios between corresponding risk curves for head injury criterion (HIC) at a 50% risk. The risk curves for BrIC were then obtained from CSDM and MPS risk curves using the linear relationship

    Rapid urbanization and motorization without corresponding increases in helmet usage have made traumatic brain injury due to road traffic accidents a major public health crisis in Cambodia. This analysis was conducted to quantify the impact of helmets on severity of injury, neurosurgical indication, and functional outcomes at discharge for motorcycle operators who required hospitalization for a traumatic brain injury following a road traffic accident in Cambodia. The medical records of 491 motorcycle operators who presented to a major tertiary care center in Cambodia with traumatic brain injury were retrospectively analyzed using multivariate logistic regression. The most common injuries at presentation were contusions (47.0%), epidural hematomas (30.1%), subdural hematomas (27.9%), subarachnoid hemorrhages (12.4%), skull fractures (21.4%), and facial fractures (18.5%). Moderate-to-severe loss of consciousness was present in 36.3% of patients. Not wearing a helmet was associated with an odds ratio of 2.20 (95% confidence interval [CI], 1.15-4.22) for presenting with moderate to severe loss of consciousness compared to helmeted patients. Craniotomy or craniectomy was indicated for evacuation of hematoma in 20.0% of cases, and nonhelmeted patients had 3.21-fold higher odds of requiring neurosurgical intervention (95% CI, 1.25-8.27). Furthermore, lack of helmet usage was associated with 2.72-fold higher odds of discharge with functional deficits (95% CI, 1.14-6.49). In total, 30.1% of patients were discharged with severe functional deficits. Helmets demonstrate a protective effect and may be an effective public health intervention to significantly reduce the burden of traumatic brain injury in Cambodia and other developing countries with increasing rates of motorization across the world.

    2018-06-01

    Full Text Available Introduction: In Africa, traumatic brain injuries frequently result from road traffic injuries and assaults. Despite limited resources and the high costs of life-saving neurosurgical interventions, secondary brain injury prevention has the potential for improving outcomes. However, nurses and other medical personnel infrequently monitor vital signs, blood sugar, and pulse oximetry and only sporadically re-assess neurological status. Methods: In one-on-one, semi-structured interviews, 27 nurses from Mulago Hospital’s emergency centre, a tertiary care trauma hospital in Kampala, Uganda, provided feedback regarding a traumatic brain injury-focused education session and use of a nursing chart for detecting secondary brain injury. The interviews explored the nurses’ confidence and perceived barriers to long-term chart implementation and traumatic brain injury care, as well as their ideas for improving this intervention. Interviews were audio recorded, transcribed, and coded using ATLAS.ti: Qualitative Data Analysis and Research Software (Cleverbridge, Inc., Chicago, USA and Microsoft Word and Excel (Microsoft Office, Redmond, USA for thematic content analysis. Results: Key findings identified in the interviews included the nurses’ attitudes toward the chart and their feelings of increased confidence in assessing and caring for these patients. The main barriers to continuous implementation included inadequate staffing and resources. Conclusion: Nurses were receptive to the education session and nursing chart, and felt that it increased their confidence and improved their ability to care for traumatic brain injured patients. However, lack of supplies, overwhelming numbers of patients, and inadequate staffing interfered with consistent monitoring of patients. The nurses offered various suggestions for improving traumatic brain injury care that should be further investigated. More research is needed to assess the applicability of a standardised

    The object of this study was to determine the mortality and neurological outcome of patients with mild traumatic brain injury (mTBI) who require neurosurgical intervention (NSI), identify clinical predictors of a poor outcome, and investigate the effect of failed nonoperative management and delayed NSI on outcome. A cross-sectional study of 10 years was performed, capturing all adults with mTBI and NSI. Primary outcome variables were mortality and Glasgow Outcome Scale (GOS) score. Patients were divided into an immediate intervention group, which received an NSI after the initial cranial CT scan, and a delayed intervention group, which had failed nonoperative management and received an NSI after 2 or more cranial CT scans. The mortality rate in mTBI patients requiring NSI was 13%, and the mean GOS score was 3.6 ± 1.2. An age > 60 years was independently predictive of a worse outcome, and epidural hematoma was independently predictive of a good outcome. Logistic regression analysis using independent variables was calculated to create a model for predicting poor neurological outcomes in patients with mTBI undergoing NSI and had 74.1% accuracy. Patients in the delayed intervention group had worse mortality (25% vs 9%) and worse mean GOS scores (2.9 ± 1.3 vs 3.7 ± 1.2) than those in the immediate intervention group. Data in this study demonstrate that patients with mTBI requiring NSI have higher mortality rates and worse neurological outcomes and should therefore be classified separately from mTBI patients not requiring NSI. Additionally, mTBI patients requiring NSI after the failure of nonoperative management have worse outcomes than those receiving immediate intervention and should be considered separately.

    To examine racial differences in employment status and occupational status 1 year after a traumatic brain injury (TBI). Retrospective study. Longitudinal dataset of the Traumatic Brain Injury Model Systems national database. Subjects with primarily moderate to severe TBI (3468 whites vs 1791 minorities) hospitalized between 1989 and 2005. Not applicable. Employment status (competitively employed or unemployed) and occupational status (professional/managerial, skilled, or manual labor) at 1 year postinjury. Race and/or ethnicity has a significant effect on employment status at 1 year postinjury (chi(1)(2)=58.23, Pstatus, sex, Disability Rating Scale at discharge, marital status, cause of injury, age, and education. The adjusted odds of being unemployed versus competitively employed are 2.17 times (95% confidence interval, 1.78-2.65) greater for minorities than for whites. Race and ethnicity does not have a significant effect on occupational status at 1 year postinjury. With this empirical evidence supporting racial differences in employment outcomes between minorities and whites at 1 year postinjury, priority should be given to tailoring interventions to maximize minority survivors' work-related productivity.

    Objective: To characterize the expression of aquaporin-4 (AQP4), one of the aquaporins (AQPs), in human brain specimens from patients with traumatic brain injury or brain tumors. Methods: Nineteen human brain specimens were obtained from the patients with traumatic brain injury, brain tumors, benign meningioma or early stage hemorrhagic stroke. MRI or CT imaging was used to assess brain edema. Hematoxylin and eosin staining were used to evaluate cell damage. Immunohistochemistry was used to detect the AQP4 expression. Results: AQP4 expression was increased from 15h to at least 8 d after injury. AQP4immunoreactivity was strong around astrocytomas, ganglioglioma and metastatic adenocarcinoma. However, AQP4 immunoreactivity was only found in the centers of astrocytomas and ganglioglioma, but not in metastatic adenocarcinoma derived from lung.Conclusion: AQP4 expression increases in human brains after traumatic brain injury, within brain-derived tumors, and around brain tumors.

    2017-01-01

    The psychological characteristics of acute traumatic brain injury (TBI) have received limited research focus, despite empirical evidence of their relevance for subsequent psychological adjustment and early therapeutic intervention. This study addressed a wide range of psychological features in 47 individuals who were hospitalized as a result of acute mild TBI (mTBI). Participants were screened from amongst consecutive TBI admissions for moderate to severe brain injury, and for pre-injury neurological, psychiatric, or substance abuse histories. Clinical and content scale scores on the MMPI-2 were explored in relation to patient gender, age, level of education, and extent of cognitive complaints. The results revealed diverse psychosocial problem areas across the sample, the most common of which were somatic and cognitive complaints, compromised insight, and a naively optimistic self-perception. The mediating roles of injury severity and demographic variables are discussed. Clinical implications and specific recommendations are presented.

    To determine the understanding of educational professionals around the topic of childhood brain injury and explore the factor structure of the Common Misconceptions about Traumatic Brain Injury Questionnaire (CM-TBI). Cross-sectional postal survey. The CM-TBI was posted to all educational establishments in one region of the UK. One representative from each school was asked to complete and return the questionnaire (n = 388). Differences were demonstrated between those participants who knew someone with a brain injury and those who did not, with a similar pattern being shown for those educators who had taught a child with brain injury. Participants who had taught a child with brain injury demonstrated greater knowledge in areas such as seatbelts/prevention, brain damage, brain injury sequelae, amnesia, recovery and rehabilitation. Principal components analysis suggested the existence of four factors and the discarding of half the original items of the questionnaire. In the first European study to explore this issue, it is highlighted that teachers are ill-prepared to cope with children who have sustained a brain injury. Given the importance of a supportive school environment in return to life following hospitalization, the lack of understanding demonstrated by teachers in this research may significantly impact on a successful return to school.

  4. Role of Melatonin in Traumatic Brain Injury and Spinal Cord Injury

    2014-01-01

    Full Text Available Brain and spinal cord are implicated in incidences of two of the most severe injuries of central nervous system (CNS. Traumatic brain injury (TBI is a devastating neurological deficit involving primary and secondary injury cascades. The primary and secondary mechanisms include complex consequences of activation of proinflammatory cytokines, cerebral edema, upregulation of NF-κβ, disruption of blood-brain barrier (BBB, and oxidative stress. Spinal cord injury (SCI includes primary and secondary injury cascades. Primary injury leads to secondary injury in which generation of free radicals and oxidative or nitrative damage play an important pathophysiological role. The indoleamine melatonin is a hormone secreted or synthesized by pineal gland in the brain which helps to regulate sleep and wake cycle. Melatonin has been shown to be a versatile hormone having antioxidative, antiapoptotic, neuroprotective, and anti-inflammatory properties. It has a special characteristic of crossing BBB. Melatonin has neuroprotective role in the injured part of the CNS after TBI and SCI. A number of studies have successfully shown its therapeutic value as a neuroprotective agent in the treatment of neurodegenerative diseases. Here in this review we have compiled the literature supporting consequences of CNS injuries, TBI and SCI, and the protective role of melatonin in it.

    2014-08-01

    This article reviews the available literature about the use of novel methods of rehabilitation using virtual reality interventions for people living with posttraumatic brain injuries. The MEDLINE, EMBASE, SCOPUS, and Cochrane Library databases were searched using the terms "virtual reality" OR "video games" AND "traumatic brain injury." Included studies investigated therapeutic use of virtual reality in adults with a brain trauma resulting from acquired closed head injury, reported outcomes that included measures of motor or cognitive functionality, and were published in a peer-reviewed journal written in English. Eighteen articles fulfilled inclusion criteria. Eight were case studies, five studies had a quasi-experimental design with a pre-post comparison, and five were pilot randomized control trials or comparative studies. The virtual reality systems used were commercial or custom designed for the study and ranged from expensive, fully immersive systems to cheap online games or videogames. In before-after comparisons, improvements in balance were seen in four case studies and two small randomized control trials. Between-group comparisons in these randomized control trials showed no difference between virtual reality and traditional therapy. Post-training improvements were also seen for upper extremity functions (five small studies) and for various cognitive function measures (four case studies and one pilot randomized control trial). Attitudes of participants toward virtual reality interventions was more positive than for traditional therapy (three studies). The evidence that the use of virtual reality in rehabilitation of traumatic brain injury improves motor and cognitive functionality is currently very limited. However, this approach has the potential to provide alternative, possibly more affordable and available rehabilitation therapy for traumatic brain injury in settings where access to therapy is limited by geographical or financial constraints.

    The Impact program is an adolescent, injury prevention program with both school- and hospital-based components aimed at decreasing high-risk behaviors and preventing injury. The objective of this study was to obtain student input on the school-based component of Impact, as part of the program evaluation and redesign process, to ensure that the program content and format were optimal and relevant, addressing injury-related issues important for youth in our region. Secondary schools were selected in various geographic regions with students varying in language, religion, and socioeconomic status. A mixed-methods questionnaire was developed and pretested on program content, format, relevance, quality, and effectiveness. Attitude and opinion questions on issues facing teens today were ranked on a 7-point Likert scale. Open-ended, qualitative questions were included in the focus groups, with responses themed. There were 167 respondents in the nine geographically, socioeconomically, and culturally diverse focus groups with a mean age of 16 years, 52% were male, and 69% were in Grade 11. Ninety-three percent of respondents rated the content of Impact as comprehensive (median, 6 of 7, with 7 being very comprehensive), and 29% rated the format a 5 of 7. Impact was rated relevant (89%), addressing issues for teens (median, 6 of 7). Issues suggested to highlight included texting and driving, drugs, partying, self-harm, and abusive relationships. Texting while driving was perceived as a significantly more common (81%) injury issue for adolescents compared with other driving risk factors (p programs must be continually evaluated to ensure they are relevant, addressing issues important for youth, and presented in a format that resonates with the audience. Student focus groups identified motor vehicle collisions and texting as important issues as well as a desire for teens to hear personal stories with a visual element. This provided the information needed to develop the next

    Psychological distress is common in teen mothers. High rates of distress are attributed to teen mothers' childhood adversities and the challenges of parenting in the context of chronic stress, cumulative disadvantage, and limited social support. We describe the prevalence of psychological distress in teen mothers; what is known about its origins and impact on mothers and children; factors that promote teen mothers' mental health and resilience; and the many barriers that make it difficult to obtain traditional mental healthcare. We also briefly review the few studies that test interventions to improve teen mothers' mental health. Because barriers to traditional mental health treatment are ubiquitous and difficult to remedy, the second article in this two-part series calls for nurses in healthcare settings, schools, and home visiting programs to screen pregnant and parenting teens for adverse childhood experiences and psychological distress, and to integrate strength-based and trauma-based principles into their practice. Creating a supportive setting where past traumas and psychological distress are addressed with skill and sensitivity builds upon teen mothers' strengths and their aspirations to be the best parents they can be. These approaches facilitate the long-term health and development of mother and child.

    To examine perspectives of multiple stakeholders to inform the design of an app-based coaching intervention to promote social participation in teenagers with traumatic brain injury (TBI). Teenagers and college students with and without TBI and parents of teenagers with TBI were recruited from two children's hospitals and two universities in the USA (n = 39). Data were collected via interviews, focus groups, and surveys and examined using descriptive statistics and content analyses. Teenagers with TBI reported more social participation barriers and fewer strategies for addressing these barriers than teenagers without TBI. There was consensus across groups about the value of college student coaches and use of smartphones and apps. Participants expressed mixed views on the use of chat rooms and degree of parent involvement. Results provided insights about the possible benefits of the intervention, and informed its initial design (e.g., desired coach qualities, and type of coach training and supervision).

    Full Text Available BackgroundPeriventricular leukomalacia (PVL is the most common form of preterm brain injury affecting the cerebral white matter. This type of injury involves a multiphase process and is induced by many factors, including hypoxia–ischemia (HI and infection. Previous studies have suggested that lymphocytes play a significant role in the pathogenesis of brain injury, and the aim of this study was to determine the contribution of lymphocyte subsets to preterm brain injury.MethodsImmunohistochemistry on brain sections from neonatal mice was performed to evaluate the extent of brain injury in wild-type and T cell and B cell-deficient neonatal mice (Rag1−/− mice using a mouse model of HI-induced preterm brain injury. Flow cytometry was performed to determine the presence of different types of immune cells in mouse brains following HI. In addition, immunostaining for CD3 T cells and CD20 B cells was performed on postmortem preterm human infant brains with PVL.ResultsMature lymphocyte-deficient Rag1−/− mice showed protection from white matter loss compared to wild type mice as indicated by myelin basic protein immunostaining of mouse brains. CD3+ T cells and CD20+ B cells were observed in the postmortem preterm infant brains with PVL. Flow cytometry analysis of mouse brains after HI-induced injury showed increased frequency of CD3+ T, αβT and B cells at 7 days after HI in the ipsilateral (injured hemisphere compared to the contralateral (control, uninjured hemisphere.ConclusionLymphocytes were found in the injured brain after injury in both mice and humans, and lack of mature lymphocytes protected neonatal mice from HI-induced brain white matter injury. This finding provides insight into the pathology of perinatal brain injury and suggests new avenues for the development of therapeutic strategies.

    Recent controversy regarding the issue of children working in family-owned businesses has come to the forefront, pitting safety and health versus parent's right to teach their children the family trade. While studies have characterized injury among working teens, no studies have assessed work and injury among teens employed in family-owned businesses. This study is the first to examine teenagers working in family-owned businesses and to compare the experiences of teens working in family-businesses to the experiences of other working teens. A questionnaire was distributed to 8,085 teens in high schools throughout the five public health regions of Wisconsin. A total of 6, 810 teens responded (84%). Overall 2,858 high school teens aged 14-17 reported working (42%); of which 963 (34%) worked in a family-business. Teens working in family-businesses were more likely to report that their injury was severe, affecting their activities for more than three days, compared with other working teens (33% vs. 21%, P = 0.05). The percentage of teens working in family-businesses that reported broken bones or crushed body parts was 17% compared to only 5% of other-working teens. Additionally, teens employed in family-businesses were more likely to file for workers' compensation (28% vs. 12%, P = 0.005). Teens working in family-owned businesses may be at a greater risk for more severe injury based on the jobs and tasks they are doing. Teens working in family-owned businesses were more likely to report engaging in dangerous tasks, including some that are illegal under the Hazardous Occupation Orders. More research is needed to assess the dynamics that exist for teens working in family-owned businesses.

    Approximately 100,000 primary and metastatic brain tumor patients/year in the US survive long enough (>6 months) to experience radiation-induced brain injury. Prior to 1970, the human brain was thought to be highly radioresistant; the acute CNS syndrome occurs after single doses >30 Gy; white matter necrosis occurs at fractionated doses >60 Gy. Although white matter necrosis is uncommon with modern techniques, functional deficits, including progressive impairments in memory, attention, and executive function have become important, because they have profound effects on quality of life. Preclinical studies have provided valuable insights into the pathogenesis of radiation-induced cognitive impairment. Given its central role in memory and neurogenesis, the majority of these studies have focused on the hippocampus. Irradiating pediatric and young adult rodent brains leads to several hippocampal changes including neuroinflammation and a marked reduction in neurogenesis. These data have been interpreted to suggest that shielding the hippocampus will prevent clinical radiation-induced cognitive impairment. However, this interpretation may be overly simplistic. Studies using older rodents, that more closely match the adult human brain tumor population, indicate that, unlike pediatric and young adult rats, older rats fail to show a radiation-induced decrease in neurogenesis or a loss of mature neurons. Nevertheless, older rats still exhibit cognitive impairment. This occurs in the absence of demyelination and/or white matter necrosis similar to what is observed clinically, suggesting that more subtle molecular, cellular and/or microanatomic modifications are involved in this radiation-induced brain injury. Given that radiation-induced cognitive impairment likely reflects damage to both hippocampal- and non-hippocampal-dependent domains, there is a critical need to investigate the microanatomic and functional effects of radiation in various brain regions as well as their

    2016-09-01

    Traumatic brain injury (TBI) has come to the forefront of both the scientific and popular culture. Specifically, sports-related concussions or mild TBI (mTBI) has become the center of scientific scrutiny with a large amount of research focusing on the long-term sequela of this type of injury. As the populace continues to age, the impact of TBI on the aging brain will become clearer. Currently, reports have come to light that link TBI to neurodegenerative disorders such as Alzheimer's and Parkinson's diseases, as well as certain psychiatric diseases. Whether these associations are causations, however, is yet to be determined. Other long-term sequelae, such as chronic traumatic encephalopathy (CTE), appear to be associated with repetitive injuries. Going forward, as we gain better understanding of the pathophysiological process involved in TBI and subclinical head traumas, and individual traits that influence susceptibility to neurocognitive diseases, a clearer, more comprehensive understanding of the connection between brain injury and resultant disease processes in the aging brain will become evident.

    Traumatic brain injuries have major socio-economic importance due to their frequency, high mortality and serious consequences. According to their nature the consequences of these injuries may be classified as neurological, psychiatric and esthetic. Various lesions of brain structures cause neurological consequences such as disturbance of motor functions, sensibility, coordination or involuntary movements, speech disturbances and other deviations, as well as epilepsy. Psychiatric consequences include cognitive deficit, emotional disturbances and behavior disturbances. CRIMINAL-LEGAL ASPECT OF TRAUMATIC BRAIN INJURIES AND LITIGATION: Criminal-legal aspect of traumatic brain injuries expertise understands the qualification of these injuries as mild, serious and qualified serious body injuries as well as the expertise about the mechanisms of their occurrence. Litigation expertise includes the estimation of pain, fear, diminished, i.e. lost vital activity and disability, esthetic marring, and psychological suffer based on the diminished general vital activity and esthetic marring. Evaluation of consequences of traumatic brain injuries should be performed only when it can be positively confirmed that they are permanent, i.e. at least one year after the injury. Expertise of these injuries is interdisciplinary. Among clinical doctors the most competent medical expert is the one who is in charge for diagnostics and injury treatment, with the recommendation to avoid, if possible, the doctor who conducted treatment. For the estimation of general vital activity, the neurological consequences, pain and esthetic marring expertise, the most competent doctors are neurosurgeon and neurologist. Psychological psychiatric consequences and fear expertise have to be performed by the psychiatrist. Specialists of forensic medicine contribute with knowledge of criminal low and legal expertise.

    Full Text Available Objective. To investigate the incidence and type of misconceptions about traumatic brain injuries (TBIs harboured by university students.  Method. A convenience sample of 705 university students were recruited and data were collected using an electronic survey. The link to the survey was sent via e-mail to all registered students at Stellenbosch University. The participants had to complete the Common Misconceptions about Traumatic Brain Injury (CM-TBI questionnaire.  Results. The findings of this study suggest that the students subscribe to misconceptions from each of the 7 categories of misconceptions about TBIs. The mean percentages of misconceptions about TBIs were calculated and the amnesia (mean 49.7% and unconsciousness (mean 46.1% categories were identified as the categories about which the respondents had the most misconceptions, while the mean percentages of misconceptions were lower for the categories of recovery (mean 27.6%, rehabilitation (mean 26.56%, prevention (mean 20.8%, brain injury sequelae (mean 18.7% and brain damage (mean 8.4%.  Conclusion. Generally, these findings appear to be in keeping with previous literature, which suggests that misconceptions about TBIs are common among the general population. This study’s identification of these misconceptions could help create awareness, provide a focus for information provision, and contribute to the development of educational intervention programmes tailored for the South African context.

    To examine the association between coping style and emotional adjustment following traumatic brain injury. Thirty three individuals who had sustained a traumatic brain injury (mean duration of posttraumatic amnesia = 32 days) between 1(1/2) months and almost 7 years previously. Coping Scale for Adults, Hospital Anxiety and Depression Scale, Rosenberg Self-Esteem Scale, State-Trait Anger Expression Inventory, and the Sickness Impact Profile. Approximately 50% of the sample reported clinically significant levels of anxiety and depression. Coping characterized by avoidance, worry, wishful thinking, self-blame, and using drugs and alcohol was associated with higher levels of anxiety, depression, and psychosocial dysfunction and lower levels of self-esteem. Coping characterized by actively working on the problem and using humor and enjoyable activities to manage stress was associated with higher self-esteem. Lower premorbid intelligence (measured via the National Adult Reading Test) and greater self-awareness (measured via the Self-Awareness of Deficits Interview) were associated with an increased rate of maladaptive coping. The strong association between the style of coping used to manage stress and emotional adjustment suggests the possibility that emotional adjustment might be improved by the facilitation of more adaptive coping styles. It is also possible that improving emotional adjustment may increase adaptive coping. The development and evaluation of interventions aimed at facilitating adaptive coping and decreasing emotional distress represent important and potentially fruitful contributions to enhancing long-term outcome following brain injury.

    2016-10-01

    On seeing promising results in a small number of patients, some researchers are conducting trials to determine whether deep brain stimulation (DBS) is an effective treatment for anorexia nervosa (AN). This article asks whether we should open enrollment in trials of DBS for AN to adolescents. Despite concerns about informed consent, parental consent, and unforeseeable psychological sequelae, the article concludes that the risks to anorexic adolescents associated with participation in trials of DBS are reasonable considering the substantial risks of not enrolling teens with AN in research on DBS. The seriousness of AN, its high incidence in teens, and serious shortfalls in the AN treatment literature point to the need for improved, evidence-based treatments for teens with AN. This unmet need generates an obligation on the part of researchers and physicians to promote and conduct research on AN in adolescents.

    Traumatic brain injury (TBI) from blast produces a number of conundrums. This review focuses on five fundamental questions including: (1) What are the physical correlates for blast TBI in humans? (2) Why is there limited evidence of traditional pulmonary injury from blast in current military field epidemiology? (3) What are the primary blast brain injury mechanisms in humans? (4) If TBI can present with clinical symptoms similar to those of Post-Traumatic Stress Disorder (PTSD), how do we clinically differentiate blast TBI from PTSD and other psychiatric conditions? (5) How do we scale experimental animal models to human response? The preponderance of the evidence from a combination of clinical practice and experimental models suggests that blast TBI from direct blast exposure occurs on the modern battlefield. Progress has been made in establishing injury risk functions in terms of blast overpressure time histories, and there is strong experimental evidence in animal models that mild brain injuries occur at blast intensities that are similar to the pulmonary injury threshold. Enhanced thoracic protection from ballistic protective body armor likely plays a role in the occurrence of blast TBI by preventing lung injuries at blast intensities that could cause TBI. Principal areas of uncertainty include the need for a more comprehensive injury assessment for mild blast injuries in humans, an improved understanding of blast TBI pathophysiology of blast TBI in animal models and humans, the relationship between clinical manifestations of PTSD and mild TBI from blunt or blast trauma including possible synergistic effects, and scaling between animals models and human exposure to blasts in wartime and terrorist attacks. Experimental methodologies, including location of the animal model relative to the shock or blast source, should be carefully designed to provide a realistic blast experiment with conditions comparable to blasts on humans. If traditional blast scaling is

    The aim of the study was to examine the utility of five measures of non-cognitive neurobehavioural (NCNB) changes that often occur following acquired brain injury, in predicting outcome (measured in terms of participation and social adaptation) at 1-year follow-up. The study employed a longitudinal, correlational design. Multiple regression was employed to investigate the value of five new NCNB measures of social perception, emotional regulation, motivation, impulsivity and disinhibition in the prediction of outcome as measured by the Mayo-Portland Adaptability Inventory (MPAI). Two NCNB measures (motivation and emotional regulation) were found to significantly predict outcome at 1-year follow-up, accounting for 53% of the variance in MPAI total scores. These measures provide a method of quantifying the extent of NCNB changes following brain injury. The predictive value of the measures indicates that they may represent a useful tool which could aid clinicians in identifying early-on those whose symptoms are likely to persist and who may require ongoing intervention. This could facilitate the planning of rehabilitation programmes.

The relative contribution of each of these pathways is not known. We hypothesised that in vivo magnetic resonance imaging (MRI can detect WM brain injury resulting from mechanical ventilation 24 h after preterm delivery. Further we hypothesised that the combination of inflammatory and haemodynamic pathways, induced by umbilical cord occlusion (UCO increases brain injury at 24 h.Fetuses at 124±2 days gestation were exposed, instrumented and either ventilated for 15 min using a high tidal-volume (VT injurious strategy with the umbilical cord intact (INJ; inflammatory pathway only, or occluded (INJ+UCO; inflammatory and haemodynamic pathway. The ventilation groups were compared to lambs that underwent surgery but were not ventilated (Sham, and lambs that did not undergo surgery (unoperated control; Cont.

    Full Text Available Brains reveal amplified plasticity as they recover from an injury. We aimed to define time dependent plasticity changes in patients recovering from mild traumatic brain injury (mTBI. 25 subjects with mild head injury were longitudinally evaluated within 36 hours, 3 and 6 months using resting state functional connectivity (RSFC. Region of interest (ROI based connectivity differences over time within the patient group and in comparison with a healthy control group were analyzed at p<0.005. We found 33 distinct ROI pairs that revealed significant changes in their connectivity strength with time. Within three months, the majority of the ROI pairs had decreased connectivity in mTBI population, which increased and became comparable to healthy controls at 6 months. Initial imaging within 36 hours of injury revealed hyper connectivity predominantly involving the salience network and default mode network, which reduced at 3 months when lingual, inferior frontal and fronto-parietal networks revealed hyper connectivity. At six months all the evaluated networks revealed hyper connectivity and became comparable to the healthy controls. Our findings in a fairly homogenous group of patients with mTBI evaluated during the 6 month window of recovery defines time varying brain connectivity changes as the brain recovers from an injury. A majority of these changes were seen in the frontal and parietal lobes between 3-6 months after injury. Hyper connectivity of several networks supported normal recovery in the first six months and it remains to be seen in future studies whether this can predict an early and efficient recovery of brain function.

    Objective To describe the theoretical basis, use, and satisfaction with Teen CHAT, an online educational intervention designed to improve physician-adolescent communication about healthy weight. Methods Routine health maintenance encounters between pediatricians and family practitioners and their overweight adolescent patients were audio recorded, and content was coded to summarize adherence with motivational interviewing techniques. An online educational intervention was developed using constructs from social cognitive theory and using personalized audio recordings. Physicians were randomized to the online intervention or not, and completed post-intervention surveys. Results Forty-six physicians were recruited, and 22 physicians were randomized to view the intervention website. The educational intervention took an average of 54 minutes to complete, and most physicians thought it was useful, that they would use newly acquired skills with their patients, and would recommend it to others. Fewer physicians thought it helped them address confidentiality issues with their adolescent patients. Conclusion The Teen CHAT online intervention shows potential for enhancing physician motivational interviewing skills in an acceptable and time-efficient manner. Practice Implications If found to be effective in enhancing motivational interviewing skills and changing adolescent weight-related behaviors, wide dissemination will be feasible and indicated.

    Serious and often lasting vision impairments affect 30% to 35% of people following stroke. Vision may be considered the most important sense in humans, and even smaller permanent injuries can drastically reduce quality of life. Restoration of visual field impairments occur only to a small extent during the first month after brain damage, and therefore the time window for spontaneous improvements is limited. One month after brain injury causing visual impairment, patients usually will experience chronically impaired vision and the need for compensatory vision rehabilitation is substantial. The purpose of this study is to investigate whether rehabilitation with Neuro Vision Technology will result in a significant and lasting improvement in functional capacity in persons with chronic visual impairments after brain injury. Improving eyesight is expected to increase both physical and mental functioning, thus improving the quality of life. This is a prospective open label trial in which participants with chronic visual field impairments are examined before and after the intervention. Participants typically suffer from stroke or traumatic brain injury and will be recruited from hospitals and The Institute for the Blind and Partially Sighted. Treatment is based on Neuro Vision Technology, which is a supervised training course, where participants are trained in compensatory techniques using specially designed equipment. Through the Neuro Vision Technology procedure, the vision problems of each individual are carefully investigated, and personal data is used to organize individual training sessions. Cognitive face-to-face assessments and self-assessed questionnaires about both life and vision quality are also applied before and after the training. Funding was provided in June 2017. Results are expected to be available in 2020. Sample size is calculated to 23 participants. Due to age, difficulty in transport, and the time-consuming intervention, up to 25% dropouts are

Methods: Between November 2011 and April 2014, PDTs were performed on 32 severe brain injury patients in ICU by a team of physicians and intensivists. The success rate, effi cacy, safety, and complications including stomal infection and bleeding, paratracheal insertion, pneumothorax, pneumomediastinum, tracheal laceration, as well as clinically significant tracheal stenosis were carefully monitored and recorded respectively. Results: The operations took 4-15 minutes (mean 9.1 minutes±4.2 minutes. Totally 4 cases suffered from complications in the operations: 3 cases of stomal bleeding, and 1 case of intratracheal bloody secretion, but none required intervention. Paratracheal insertion, pneumothorax, pneumomediastinum, tracheal laceration, or clinically signifi cant tracheal stenosis were not found in PDT patients. There was no procedure-related death occurring during or after PDT. Conclusion: Our study demonstrats that PDT is a safe, highly effective, and minimally invasive procedure. The appropriate sedation and airway management perioperatively help to reduce complication rates. PDT should be performed or supervised by a team of physicians with extensive experience in this procedure, and also an intensivist with experience in diffi cult airway management.

    We determine the relative risk and severity of traumatic brain injury among occupants of lateral impacts compared with occupants of nonlateral impacts. This was a secondary analysis of the National Highway Traffic Safety Administration's National Automotive Sampling System, Crashworthiness Data Systems for 2000. Analysis was restricted to occupants of vehicles in which at least 1 person experienced an injury with Abbreviated Injury Scale score greater than 2. Traumatic brain injury was defined as an injury to the head or skull with an Abbreviated Injury Scale score greater than 2. Outcomes were analyzed using the chi2 test and multivariate logistic regression, with adjustment of variance to account for weighted probability sampling. Of the 1,115 occupants available for analysis, impact direction was lateral for 230 (18.42%) occupants and nonlateral for 885 (81.58%) occupants. One hundred eighty-seven (16.07%) occupants experienced a traumatic brain injury, 14.63% after lateral and 16.39% after nonlateral impact. The unadjusted relative risk of traumatic brain injury after lateral impact was 0.89 (95% confidence interval [CI] 0.51 to 1.56). After adjusting for several important crash-related variables, the relative risk of traumatic brain injury was 2.60 (95% CI 1.1 to 6.0). Traumatic brain injuries were more severe after lateral impact according to Abbreviated Injury Scale and Glasgow Coma Scale scores. The proportion of fatal or critical crash-related traumatic brain injuries attributable to lateral impact was 23.5%. Lateral impact is an important independent risk factor for the development of traumatic brain injury after a serious motor vehicle crash. Traumatic brain injuries incurred after lateral impact are more severe than those resulting from nonlateral impact. Vehicle modifications that increase head protection could reduce crash-related severe traumatic brain injuries by up to 61% and prevent up to 2,230 fatal or critical traumatic brain injuries each year

    To evaluate the effectiveness of the Nintendo Wii compared to traditional balance therapy in improving balance, motivation, and functional ability in children undergoing acute rehabilitation after brain injury. A non-concurrent, randomized multiple baseline single-subject research design was used with three participants. Data were analyzed by visual inspection of trend lines. Daily Wii balance training was equally motivating to traditional balance therapy for two participants and more motivating for one participant. While improvements in dynamic balance were observed, the results for static balance remain inconclusive. All participants demonstrated improvements in functional ability. Wii balance therapy is a safe, feasible, and motivating intervention for children undergoing acute rehabilitation after an acquired brain injury. Further research to examine the effectiveness of Wii balance therapy in this population is warranted.

    2012-12-01

    Brain injury is a major cause of long-term disability. Executive and social cognition sequelae are associated with poor outcome. This review examines recent evidence on the efficacy of rehabilitation in these areas. Accumulating evidence shows that interventions that work with patients on developing insight and strategies to offset executive impairments can produce significant benefits. Training of specific capacities, such as working memory, holds some promise, but more needs to be known about effect generalization. Evidence on social cognition rehabilitation following brain injury is sparse. Although there are some encouraging early results, more information on the clinical significance of change for everyday function is required. Rehabilitation in these areas is inherently difficult but vital if outcomes are to improve. Significant gains have been reported, and further work applying appropriate methods is urgently required.

  16. The Change in Nutritional Status in Traumatic Brain Injury Patients: A Retrospective Descriptive Study

    Science.gov (United States)

    Masha'al, Dina A.

    There is a high prevalence in malnutrition among traumatic brain injury (TBI) due to the hypermetabolism and hypercatabolism which develop post injury. Traumatic brain injury patients are different, even among themselves, in their energy requirements and response to nutritional therapy. This implies that there are other factors that affect the energy intake of these patients and enhance the incidence of malnutrition. This dissertation study examines the nutritional status of TBI patients upon admission to the intensive care unit (ICU) and during their hospital stay to describe baseline status, detect changes in nutritional status over 7 days, and identify the factors affecting the adequacy of energy intake and the change in nutritional status as a consequence. Anthropometric measurements, biomedical measurements, measures of severity of illness, daily health status, level of brain injury severity, and other data were collected from the medical records of 50 patients, who were ≥ 18 years old, mechanically ventilated in the first 24 hours of ICU admission, and had a Glasgow Coma Scale score between 3-12. These data were used to examine the previous relationships. Although there was no statistically significant change found in body mass index and weight, there was a significant change detected in other nutritional markers, including hemoglobin, albumin, and total lymphocyte levels over the 7 days of ICU and hospital stay. No significant relationship was found between the adequacy of energy intake and total prescribed energy, severity of illness, level of brain injury severity, daily health status, patient age, intracranial pressure, or time of feeding initiation. Findings may be used to develop and test interventions to improve nutritional status during the acute phase of TBI. This will lay a foundation for health care providers, including nurses, to establish standards for practice and nutrition protocols to assure optimal nutrition assessment and intervention in a

    Attention-deficit/hyperactivity disorder (ADHD) presents in childhood with inattention, hyperactivity, and impulsivity and is associated with functional impairments. These children tend to display a variety of disruptive behaviors, which may worsen in adolescence. Teens with ADHD may show high levels of defiance, posing significant challenges for parents. Early efforts to understand parenting in the context of teen ADHD reveal high levels of parental stress and reactivity in response to the teen's ADHD symptoms. Subsequent research recognized that some of these parents have ADHD or other psychopathology that may contribute to maladaptive parenting. However, some parents adjust and demonstrate optimism and resilience in the face of their teens' ADHD. Recent research has identified parental factors (eg, emotional intelligence) and interventions (eg, mindfulness training) that may improve parenting/teen relationships and the developmental outcomes of teens. This article explores parenting teens with ADHD with a focus on these novel interventions. © The Author(s) 2014.

    Axonal degeneration is a critical, early event in many acute and chronic neurological disorders. It has been consistently observed after traumatic brain injury, but whether axon degeneration is a driver of traumatic brain injury remains unclear. Molecular pathways underlying the pathology of traumatic brain injury have not been defined, and there is no efficacious treatment for traumatic brain injury. Here we show that mice lacking the mouse Toll receptor adaptor Sarm1 (sterile α/Armadillo/Toll-Interleukin receptor homology domain protein) gene, a key mediator of Wallerian degeneration, demonstrate multiple improved traumatic brain injury-associated phenotypes after injury in a closed-head mild traumatic brain injury model. Sarm1(-/-) mice developed fewer β-amyloid precursor protein aggregates in axons of the corpus callosum after traumatic brain injury as compared to Sarm1(+/+) mice. Furthermore, mice lacking Sarm1 had reduced plasma concentrations of the phophorylated axonal neurofilament subunit H, indicating that axonal integrity is maintained after traumatic brain injury. Strikingly, whereas wild-type mice exibited a number of behavioural deficits after traumatic brain injury, we observed a strong, early preservation of neurological function in Sarm1(-/-) animals. Finally, using in vivo proton magnetic resonance spectroscopy we found tissue signatures consistent with substantially preserved neuronal energy metabolism in Sarm1(-/-) mice compared to controls immediately following traumatic brain injury. Our results indicate that the SARM1-mediated prodegenerative pathway promotes pathogenesis in traumatic brain injury and suggest that anti-SARM1 therapeutics are a viable approach for preserving neurological function after traumatic brain injury. © The Author (2016).

    2015-01-01

    Inattention to the roadway, including cell phone use while driving (cell phone calls, sending and reading texts, mobile app use, and Internet use), is a critical problem for teen drivers and increases risk for crashes. Effective behavioral interventions for teens are needed in order to decrease teen driver inattention related to cell phone use while driving. However, teens' perceptions of mobile device use while driving is a necessary component for theoretically driven behavior change interventions. The purpose of this study was to describe teen drivers' perceptions of cell phone use while driving in order to inform future interventions to reduce risky driving. We conducted 7 focus groups with a total of 30 teen drivers, ages 16-18, licensed for ≤ 1 year in Pennsylvania. The focus group interview guide and analysis were based on the Theory of Planned Behavior, identifying the attitudes, perceived behavioral control, and norms about inattention to the roadway. Directed descriptive content analysis was used to analyze the focus group interviews. All focus groups were coded by 2 research team members and discrepancies were reconciled. Themes were developed based on the data. Teens had a mean age of 17.39 (SD = 0.52), mean length of licensure of 173.7 days (SD = 109.2; range 4-364), were 50% male and predominately white (90%) and non-Hispanic (97%). From the focus group data, 3 major themes emerged: (1) Recognizing the danger but still engaging; (2) Considering context; and (3) Formulating safer behaviors that might reduce risk. Despite recognizing that handheld cell phone use, texting, and social media app use are dangerous and distracting while driving, teens and their peers often engaged in these behaviors. Teens described how the context of the situation contributed to whether a teen would place or answer a call, write or respond to a text, or use a social media app. Teens identified ways in which they controlled their behaviors, although some still drew

    Individuals with brain injury often present with cognitive, physical and emotional impairments which impact their ability to resume independence in activities of daily living. Of those activities, the resumption of driving privileges is cited as one of the greatest concerns by survivors of brain injury. The integration of driving fundamentals within the hierarchical model proposed by Keskinen represents the complexity of skills and behaviors necessary for driving. This paper provides a brief review of specific considerations concerning the driver with TBI and highlights current vehicle technology which has been developed by the automotive industry and by manufacturers of adaptive driving equipment that may facilitate the driving task. Adaptive equipment technology allows for compensation of a variety of operational deficits, whereas technological advances within the automotive industry provide drivers with improved safety and information systems. However, research has not yet supported the use of such intelligent transportation systems or advanced driving systems for drivers with brain injury. Although technologies are intended to improve the safety of drivers within the general population, the potential of negative consequences for drivers with brain injury must be considered. Ultimately, a comprehensive driving evaluation and training by a driving rehabilitation specialist is recommended for individuals with brain injury. An understanding of the potential impact of TBI on driving-related skills and knowledge of current adaptive equipment and technology is imperative to determine whether return-to-driving is a realistic and achievable goal for the individual with TBI.

    Brain injuries are becoming increasingly common in athletes and represent an important diagnostic challenge. Early detection and management of brain injuries in sports are of utmost importance in preventing chronic neurological and psychiatric decline. These types of injuries incurred during sports are referred to as mild traumatic brain injuries, which represent a heterogeneous spectrum of disease. The most dramatic manifestation of chronic mild traumatic brain injuries is termed chronic traumatic encephalopathy, which is associated with profound neuropsychiatric deficits. Because chronic traumatic encephalopathy can only be diagnosed by postmortem examination, new diagnostic methodologies are needed for early detection and amelioration of disease burden. This review examines the pathology driving changes in athletes participating in high-impact sports and how this understanding can lead to innovations in neuroimaging and biomarker discovery.

    Teen pregnancy has been subject of public concern for many years. In the United States, despite nearly 2 decades of declining teen pregnancy and birth rates, the problem persists, with significant disparities present across racial groups and in state-specific rates. This review examines recent trends, pregnancy prevention initiatives and family planning policies that address the special needs of vulnerable youth. Unintended teen pregnancies impose potentially serious social and health burdens on teen parents and their children, as well as costs to society. Trends in teen pregnancy and birth rates show continued decline, but state and racial disparities have widened. Demographic factors and policy changes have contributed to these disparities. Research supports comprehensive pregnancy prevention initiatives that are multifaceted and promote consistent and correct use of effective methods of contraception for youth at risk of becoming pregnant. There is strong consensus that effective teen pregnancy prevention strategies should be multifaceted, focusing on delay of sexual activity especially in younger teens while promoting consistent and correct use of effective methods of contraception for those youth who are or plan to be sexually active. There is a need for further research to identify effective interventions for vulnerable populations.

    2015-01-01

    Background Despite advances in both prevention and treatment, traumatic brain injury (TBI) remains one of the most burdensome diseases; 2% of the US population currently lives with disabilities resulting from TBI. Recent advances in the understanding of inflammation and its impact on the pathophysiology of trauma have increased the interest in inflammation as a possible mediator in TBI outcome. Objectives The goal of this systematic review is to address the question: “What is the evidence in humans that inflammation is linked to secondary brain injury?” As the experimental evidence has been well described elsewhere, this review will focus on the clinical evidence for inflammation as a mechanism of secondary brain injury. Data Sources Medline database (1996-Week 1 June 2014), Pubmed and Google Scholar databases were queried for relevant studies. Study Eligibility Criteria Studies were eligible if participants were adults and/or children who sustained moderate or severe TBI in the acute phase of injury, published in English. Studies published in the last decade (since 2004) were preferentially included. Trials could be observational or interventional in nature. Appraisal and Synthesis Methods To address the quality of the studies retrieved, we applied the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) criteria to assess the limitations of the included studies. Results Trauma initiates local central nervous system as well as systemic immune activation. Numerous observational studies describe elevation of pro-inflammatory cytokines that are associated with important clinical variables including neurologic outcome and mortality. A small number of clinical trials have included immunomodulating strategies, but no intervention to date has proven effective in improving outcomes after TBI. Limitations Inclusion of studies not initially retrieved by the search terms may have biased our results. Additionally, some reports may have been

    Iron plays an important role in brain injury after intracerebral hemorrhage (ICH). Our previous study found minocycline reduces iron overload after ICH. The present study examined the effects of minocycline on the subacute brain injury induced by iron. Rats had an intracaudate injection of 50 μl of saline, iron, or iron + minocycline. All the animals were euthanized at day 3. Rat brains were used for immunohistochemistry (n = 5-6 per each group) and Western blotting assay (n = 4). Brain swelling, blood-brain barrier (BBB) disruption, and iron-handling proteins were measured. We found that intracerebral injection of iron resulted in brain swelling, BBB disruption, and brain iron-handling protein upregulation (p minocycline with iron significantly reduced iron-induced brain swelling (n = 5, p Minocycline significantly decreased albumin protein levels in the ipsilateral basal ganglia (p minocycline co-injected animals. In conclusion, the present study suggests that minocycline attenuates brain swelling and BBB disruption via an iron-chelation mechanism.

    Diabetes mellitus is a risk for brain injury. Brain injury is associated with acute and chronic hyperglycaemia, insulin resistance, hyperinsulinemia, diabetic ketoacidosis (DKA) and hypoglycaemic events in diabetic patients. Hyperglycemia is a cause of cognitive deterioration, low intelligent quotient, neurodegeneration, brain aging, brain atrophy and dementia. Areas covered: The current review highlights the experimental, clinical, neuroimaging and neuropathological evidence of brain injury induced by diabetes and its associated metabolic derangements. It also highlights the mechanisms of diabetes-induced brain injury. It seems that the pathogenesis of hyperglycemia-induced brain injury is complex and includes combination of vascular disease, oxidative stress, neuroinflammation, mitochondrial dysfunction, apoptosis, reduction of neurotrophic factors, acetylcholinesterase (AChE) activation, neurotransmitters' changes, impairment of brain repair processes, impairment of brain glymphatic system, accumulation of amyloid β and tau phosphorylation and neurodegeneration. The potentials for prevention and treatment are also discussed. Expert commentary: We summarize the risks and the possible mechanisms of DM-induced brain injury and recommend strategies for neuroprotection and neurorestoration. Recently, a number of drugs and substances [in addition to insulin and its mimics] have shown promising potentials against diabetes-induced brain injury. These include: antioxidants, neuroinflammation inhibitors, anti-apoptotics, neurotrophic factors, AChE inhibitors, mitochondrial function modifiers and cell based therapies.

    Epilepsy after pediatric traumatic brain injury (TBI) is associated with poor quality of life. This study aimed to characterize post-traumatic epilepsy in a mouse model of pediatric brain injury, and to evaluate the role of interleukin-1 (IL-1) signaling as a target for pharmacological intervention. Male mice received a controlled cortical impact or sham surgery at postnatal day 21, approximating a toddler-aged child. Mice were treated acutely with an IL-1 receptor antagonist (IL-1Ra; 100 mg/kg, s.c.) or vehicle. Spontaneous and evoked seizures were evaluated from video-EEG recordings. Behavioral assays tested for functional outcomes, postmortem analyses assessed neuropathology, and brain atrophy was detected by ex vivo magnetic resonance imaging. At 2 weeks and 3 months post-injury, TBI mice showed an elevated seizure response to the convulsant pentylenetetrazol compared with sham mice, associated with abnormal hippocampal mossy fiber sprouting. A robust increase in IL-1β and IL-1 receptor were detected after TBI. IL-1Ra treatment reduced seizure susceptibility 2 weeks after TBI compared with vehicle, and a reduction in hippocampal astrogliosis. In a chronic study, IL-1Ra-TBI mice showed improved spatial memory at 4 months post-injury. At 5 months, most TBI mice exhibited spontaneous seizures during a 7 d video-EEG recording period. At 6 months, IL-1Ra-TBI mice had fewer evoked seizures compared with vehicle controls, coinciding with greater preservation of cortical tissue. Findings demonstrate this model's utility to delineate mechanisms underlying epileptogenesis after pediatric brain injury, and provide evidence of IL-1 signaling as a mediator of post-traumatic astrogliosis and seizure susceptibility. SIGNIFICANCE STATEMENT Epilepsy is a common cause of morbidity after traumatic brain injury in early childhood. However, a limited understanding of how epilepsy develops, particularly in the immature brain, likely contributes to the lack of efficacious treatments

    Following traumatic brain injury (TBI) SUR1-regulated NCCa-ATP (SUR1/TRPM4) channels are transcriptionally up-regulated in ischemic astrocytes, neurons, and capillaries. ATP depletion results in depolarization and opening of the channel leading to cytotoxic edema. Glibenclamide is an inhibitor of SUR-1 and, thus, might prevent cytotoxic edema and secondary brain damage following TBI. Anesthetized adult Sprague-Dawley rats underwent parietal craniotomy and were subjected to controlled cortical impact injury (CCI). Glibenclamide was administered as a bolus injection 15min after CCI injury and continuously via osmotic pumps throughout 7days. In an acute trial (180min) mean arterial blood pressure, heart rate, intracranial pressure, encephalographic activity, and cerebral metabolism were monitored. Brain water content was assessed gravimetrically 24h after CCI injury and contusion volumes were measured by MRI scanning technique at 8h, 24h, 72h, and 7d post injury. Throughout the entire time of observation neurological function was quantified using the "beam-walking" test. Glibenclamide-treated animals showed a significant reduction in the development of brain tissue water content(80.47%±0.37% (glibenclamide) vs. 80.83%±0.44% (control); pbeam-walking test throughout 7days. In accordance to these results and the available literature, glibenclamide seems to have promising potency in the treatment of TBI. Copyright © 2014 IBRO. Published by Elsevier Ltd.

    The objective of the study was to develop statistical formulas to predict levels of community participation on discharge from post-hospital brain injury rehabilitation using retrospective data analysis. Data were collected from seven geographically distinct programmes in a home- and community-based brain injury rehabilitation provider network. Participants were 642 individuals with post-traumatic brain injury. Interventions consisted of home- and community-based brain injury rehabilitation. The main outcome measure was the Mayo-Portland Adaptability Inventory (MPAI-4) Participation Index. Linear discriminant models using admission MPAI-4 Participation Index score and log chronicity correctly predicted excellent (no to minimal participation limitations), very good (very mild participation limitations), good (mild participation limitations), and limited (significant participation limitations) outcome levels at discharge. Predicting broad outcome categories for post-hospital rehabilitation programmes based on admission assessment data appears feasible and valid. Equations to provide patients and families with probability statements on admission about expected levels of outcome are provided. It is unknown to what degree these prediction equations can be reliably applied and valid in other settings.

    To evaluate comprehensive day treatment (CDT) for survivors of brain injury by time since injury and to identify outcome predictors. Before and after. Rehabilitation center. Ninety-six program graduates; 17 dropouts with acquired brain injury. Comprehensive Day Treatment Program: daily group sessions to build cognitive and behavioral skills through a transdisciplinary approach, supportive feedback, and a variety of therapeutic modalities. Obtained outcome measures before and after the program, and at 1-year follow-up. Independent living status, vocational independence scale at program end and 1-year follow-up; and Rasch-analyzed Mayo-Portland Adaptability Inventory (MPAI-22) and goal attainment scaling (GAS) at program end. age, education, severity of initial injury, time since injury, and preadmission MPAI-22. Significant goal achievement on GAS and improvement on MPAI-22; increased societal participation at 1-year follow-up for those treated postacutely and many years after injury: 72% of graduates living independently; 39% working independently, 10% in transitional placements, and 18% in supported or volunteer work. Long-term outcomes were modestly related linearly to preadmission MPAI-22 and nonlinearly to time since injury. CDT improves societal participation even among persons with a long history of limited participation after brain injury. This de facto extended baseline analysis indicates the effectiveness of CDT and paves the way for randomized control trials of active treatment components. Relationships of predictors to outcomes are not sufficiently strong for patient selection. More effective interventions for vocational reintegration are needed for those most severely disabled after brain injury.

    2016-01-01

    This systematic review presents research on the effectiveness of occupation- and activity-based interventions to improve everyday activities and areas of occupation and social participation for people with traumatic brain injury (TBI). Nineteen studies identified through a comprehensive database search were reviewed and synthesized into five themes: (1) multidisciplinary and interdisciplinary treatment approaches, (2) community-based rehabilitation programs, (3) treatment approaches using client-centered goals and relevant contexts, (4) social skills training and peer mentoring interventions, and (5) community mobility interventions. Evidence supports the use of multidisciplinary and interdisciplinary approaches across a variety of settings, with no single treatment approach or setting clearly superior to another. The specific contributions of occupational therapy practitioners and the nature of occupational therapy interventions have not been well studied, making it difficult to determine the extent to which occupation- and activity-based interventions provided by occupational therapy practitioners improve occupational performance and social participation after TBI.

    Youth living in group home settings are at significantly greater risk for sexual risk behaviors; however, there are no sexual health programs designed specifically for these youth. The study's purpose was to assess the effectiveness of a teen pregnancy-prevention program for youth living in group home foster care settings and other out-of-home placements. The study design was a cluster randomized controlled trial involving youth (N = 1,037) recruited from 44 residential group homes located in California, Maryland, and Oklahoma. Within each state, youth (mean age = 16.2 years; 82% male; 37% Hispanic, 20% African-American, 20% white, and 17% multiracial) in half the group homes were randomly assigned to the intervention group (n = 40 clusters) and the other half were randomly assigned to a control group that offered "usual care" (n = 40 clusters). The intervention (i.e., Power Through Choices [PTC]) was a 10-session, age-appropriate, and medically accurate sexual health education program. Compared to the control group, youth in the PTC intervention showed significantly greater improvements (p attitude areas, all three self-efficacy areas, and two of three behavioral intention areas. This is the first published randomized controlled trial of a teen pregnancy-prevention program designed for youth living in foster care settings and other out-of-home placements. The numerous significant improvements in short-term outcomes are encouraging and provide preliminary evidence that the PTC program is an effective pregnancy-prevention program.

    2016-01-01

    To date, reviews of rehabilitation efficacy after traumatic brain injury (TBI) have overlooked the impact on sense of self, focusing instead on functional impairment and psychological distress. The present review sought to address this gap by critically appraising the methodology and efficacy of intervention studies that assess changes in self-concept. A systematic search of PsycINFO, Medline, CINAHL and PubMed was conducted from inception to September 2013 to identify studies reporting pre- and post-intervention changes on validated measures of self-esteem or self-concept in adults with TBI. Methodological quality of randomised controlled trials (RCTs) was examined using the Physiotherapy Evidence Database (PEDro) scale. A total of 17 studies (10 RCTs, 4 non-RCT group studies, 3 case studies) was identified, which examined the impact of psychotherapy, family-based support, cognitive rehabilitation or activity-based interventions on self-concept. The findings on the efficacy of these interventions were mixed, with only 10 studies showing some evidence of improvement in self-concept based on within-group or pre-post comparisons. Such findings highlight the need for greater focus on the impact of rehabilitation on self-understanding with improved assessment and intervention methodology. We draw upon theories of identity reconstruction and highlight implications for the design and evaluation of identity-oriented interventions that can supplement existing rehabilitation programmes for people with TBI.

    Teen dating violence is a serious public health problem. A cluster-randomized trial was conducted to assess the efficacy of Teen Choices , a 3-session online program that delivers assessments and individualized guidance matched to dating history, dating violence experiences, and stage of readiness for using healthy relationship skills. For high risk victims of dating violence, the program addresses readiness to keep oneself safe in relationships. Twenty high schools were randomly assigned to the Teen Choices condition ( n =2,000) or a Comparison condition ( n =1,901). Emotional and physical dating violence victimization and perpetration were assessed at 6 and 12 months in the subset of participants (total n =2,605) who reported a past-year history of dating violence at baseline, and/or who dated during the study. The Teen Choices program was associated with significantly reduced odds of all four types of dating violence (adjusted ORs ranging from .45 to .63 at 12 months follow-up). For three of the four violence outcomes, participants with a past-year history of that type of violence benefited significantly more from the intervention than students without a past-year history. The Teen Choices program provides an effective and practicable strategy for intervention for teen dating violence prevention.

    Several clinical and experimental studies have shown that lung injury occurs shortly after brain damage. The responsible mechanisms involve neurogenic pulmonary edema, inflammation, the harmful action of neurotransmitters, or autonomic system dysfunction. Mechanical ventilation, an essential component of life support in brain-damaged patients (BD), may be an additional traumatic factor to the already injured or susceptible to injury lungs of these patients thus worsening lung injury, in case ...

  20. Biomarkers of brain injury in the premature infant

    2013-01-01

    Full Text Available The term encephalopathy of prematurity encompasses not only the acute brain injury (such as intraventricular hemorrhage but also complex disturbance on the infant’s subsequent brain development. In premature infants, the most frequent recognized source of brain injury is intraventricular hemorrhage (IVH and periventricular leukomalacia (PVL. Furthermore 20-25% infants with birth weigh less than 1,500 g will have IVH and that proportion increases to 45% if the birth weight is less than 500-750 g. In addition, nearly 60% of very low birth weight newborns will have hypoxic-ischemic injury. Therefore permanent lifetime neurodevelopmental disabilities are frequent in premature infants. Innovative approach to prevent or decrease brain injury in preterm infants requires discovery of biomarkers able to discriminate infants at risk for injury, monitor the progression of the injury and assess efficacy of neuroprotective clinical trials. In this article, we will review biomarkers studied in premature infants with IVH, Post-hemorrhagic ventricular dilation (PHVD and PVL including: S100b, Activin A, erythropoietin, chemokine CCL 18, GFAP and NFL will also be examined. Some of the most promising biomarkers for IVH are S100β and Activin. The concentrations of TGF-β1, MMP-9 and PAI-1 in cerebrospinal fluid could be used to discriminate patients that will require shunt after post-hemorrhagic ventricular dilation. Neonatal brain injury is frequent in premature infants admitted to the neonatal intensive care and we hope to contribute to the awareness and interest in clinical validation of established as well as novel neonatal brain injury biomarkers.

    Treatment for delayed brain injury after pituitary irradiation is discussed. Six cases with delayed brain injury were treated with a combination of dexamethasone or betamethasone, with heparin, glycerol, dextran 40 and some vasodilators. Two cases with temporal lobe syndrome were treated in the early stages of brain injury for a period of over 12 months were almost completely cured, another two cases with chiasma syndrome were treated in the relatively late stages, showed a partial improvement. One case which was irradiated 120 GY during 13 years did not improve. The final case treated with steroids for a short period also resulted in failure and the patient underwent an operation for the removal of the necrotic mass three years after the radiotherapy. Steroid therapy started in the early stages of brain injury after irradiation for over the 12 months is thought to be effective. Heparin therapy was also effective in one out of three cases, but in one of the cases subarachnoid hemorrhage from a traumatic aneurysm occurred during the therapy. In an acute phase, showing edematous change of the injured brain, the administration of glycerol is also thought to be useful. But the effectiveness of the other medicines containing some vasodilators was obscure or doubtful. We propose the following : (1) A meticulous observation is essential for the patients who received high doses of irradiation to diagnose brain injury in the early reversible stage. (2) Steroids should be given immediately in this reversible stage of brain injury before the irreversible ''necrosis'' occurs. (3) Steroids should be maintained for a long period over 12 months. (4) Heparin therapy is also thought to be effective, but careful precautions to avoid hemorrhagic complications before the therapy should be scheduled. This recommended plan may also be used for the treatment of brain injuries after cranial irradiation for other intracranial tumors. (author)

    At present there are no standardized recommendations concerning physiotherapy of individuals with traumatic brain injury (TBI) resulting in a high variability of methods and intensity. The aim of this literature review is to develop recommendations concerning physiotherapy in the post-acute phase after TBI on the basis of scientific evidence. literature review: data bases: PubMed, PEDro, OT-Seeker, Cochrane and Cinahl. brain injury (in PEDro, OT-Seeker, Cochrane), brain injury AND physical therapy (in PubMed and Cinahl). Fourteen studies met the inclusion criteria and were grouped into sub-groups: sensory stimulation, therapy intensity, casting/splinting, exercise or aerobic training and functional skill training. While for sensory stimulation evidence could not be proven, a strong evidence exists that more intensive rehabilitation programmes lead to earlier functional abilities. The recommendation due to casting for the improvement of passive range of motion is a grade B, while only a C recommendation is appropriate concerning tonus reduction. Strong evidence exists that intensive task-orientated rehabilitation programmes lead to earlier and better functional abilities. Although some recommendations for the effectiveness of physical therapy interventions could be expressed, there are many questions concerning the treatment of humans with TBI which have not been investigated so far. Especially on the level of activity and participation only a few studies exist.

    The purpose of this study is to evaluate the radiological findings and effectiveness of radiological interventions in patients with iatrogenic vascular injuries. We analyzed 50 patients with iatrogenic vascular injuries treated with radiological intervention. The causes of injuries were surgery (n=20), cardiovascular intervention (n=15), non-cardiovascular radiological intervention (n=14), and endoscopic intervention (n=1). The injury had resulted in hemorrhage in 35 cases. The iliac and/or femoral, hepatic, and renal vessels were commonly injured. Angiography, ultrasonography with Doppler examination, CT, and CT angiography were performed to diagnose vascular injuries and guide the radiological intervention. The mean follow-up period was 23 months and in 16 cases was more than one year. the major radiological findings were extravasation, pseudoaneurysm, arteriovenous shunt, or vascular obstruction. To control these lesions, radiological interventions such as embolization (n=36), local urokinase administration, stent insertion, foreign body removal, ultrasonography-guided compression, or stent-graft insertion were performed. The clinical problems were immediately controlled by the single trials of radiological interventions and did not recur in 40 cases (80%). Radiological examinations and interventions are useful in cases with iatrogenic vascular injuries. (author). 14 refs., 4 figs

    2014-03-01

    Full Text Available This study investigated injury patterns and the use of computed tomography (CT among Chinese children with mild traumatic brain injury (MTBI. We enrolled children with MTBI who were treated within 24 hours of head trauma in the emergency department of Wuhan Medical Care Center for Women and Children in Wuhan, China. Characteristics of MTBIs were analyzed by age and gender. Results of cranial CT scan and clinically-important brain injury (ciTBI for children were obtained. The definition of ciTBI was: death from TBI, intubation for more than 24 h for TBI, neurosurgery, or hospital admission of 2 nights or more. Of 455 eligible patients with MTBI, ciTBI occurred in two, and no one underwent neurosurgical intervention. CT scans were performed for 441 TBI patients (96.9%, and abnormal findings were reported for 147 patients (33.3%, 95% CI 29.0–37.8. Falls were the leading cause of MTBI (61.5%, followed by blows (18.9% and traffic collisions (14.1% for children in the 0–2 group and 10–14 group. For children aged between 3 and 9, the top three causes of TBI were falls, traffic collisions and blows. Leisure activity was the most reported activity when injuries occurred for all age groups. Sleeping/resting and walking ranked in the second and third place for children between 0 and 2 years of age, and walking and riding for the other two groups. The places where the majority injuries occurred were the home for the 0–2 and 3–9 years of age groups, and school for the 10–14 years of age group. There was no statistical difference between boys and girls with regard to the activity that caused the MTBI. This study highlights the important roles that parents and school administrators in the development of preventive measures to reduce the risk of traumatic brain injury in children. Also, identifying children who had a head trauma at very low risk of clinically important TBI for whom CT might be unnecessary is a priority area of research in China.

    This qualitative research focused on the relationships between family members of patients with acquired brain injury (ABI). The aim was to explore the dynamics between caregivers of the family member with a brain injury during rehabilitation hospitalization, and the relationships between them and the rest of the extended family. Twenty semistructured interviews were conducted with family members. In each family, the spouse of the patient and another family member involved in caregiving were interviewed. The importance of the relationships between family members during rehabilitation hospitalization justifies the examination undertaken in this research. Findings point at the change that took place in the relationships between family members because of the need to cope with a relative's injury. It is possible that direct intervention in the dynamics of the relationship, especially between the family of origin and the nuclear family of the injured person, can benefit extended families in coping with the crisis.

  10. MicroRNAs as diagnostic markers and therapeutic targets for traumatic brain injury

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Traumatic brain injury (TBI is characterized by primary damage to the brain from the external mechanical force and by subsequent secondary injury due to various molecular and pathophysiological responses that eventually lead to neuronal cell death. Secondary brain injury events may occur minutes, hours, or even days after the trauma, and provide valuable therapeutic targets to prevent further neuronal degeneration. At the present time, there is no effective treatment for TBI due, in part, to the widespread impact of numerous complex secondary biochemical and pathophysiological events occurring at different time points following the initial injury. MicroRNAs control a range of physiological and pathological functions such as development, differentiation, apoptosis and metabolism, and may serve as potential targets for progress assessment and intervention against TBI to mitigate secondary damage to the brain. This has implications regarding improving the diagnostic accuracy of brain impairment and long-term outcomes as well as potential novel treatments. Recent human studies have identified specific microRNAs in serum/plasma (miR-425-p, -21, -93, -191 and -499 and cerebro-spinal fluid (CSF (miR-328, -362-3p, -451, -486a as possible indicators of the diagnosis, severity, and prognosis of TBI. Experimental animal studies have examined specific microRNAs as biomarkers and therapeutic targets for moderate and mild TBI (e.g., miR-21, miR-23b. MicroRNA profiling was altered by voluntary exercise. Differences in basal microRNA expression in the brain of adult and aged animals and alterations in response to TBI (e.g., miR-21 have also been reported. Further large-scale studies with TBI patients are needed to provide more information on the changes in microRNA profiles in different age groups (children, adults, and elderly.

    To increase teen seat belt use among drivers at a rural high school by implementing the Drive Alive Pilot Program (DAPP), a theory-driven intervention built on highway safety best practices. The first component of the program was 20 observational teen seat belt surveys conducted by volunteer students in a high school parking lot over a 38-month period before and after the month-long intervention. The survey results were published in the newspaper. The second component was the use of incentives, such as gift cards, to promote teen seat belt use. The third component involved disincentives, such as increased police patrol and school policies. The fourth component was a programmatic intervention that focused on education and media coverage of the DAPP program. Eleven pre-intervention surveys and nine post-intervention surveys were conducted before and after the intervention. The pre- and post-intervention seat belt usage showed significant differences (p<0.0001). The average pre-intervention seat belt usage rate was 51.2%, while the average post-intervention rate was 74.5%. This represents a percentage point increase of 23.3 in seat belt use after the DAPP intervention. Based on seat belt observational surveys, the DAPP was effective in increasing seat belt use among rural high school teenagers. Utilizing a theory-based program that builds on existing best practices can increase the observed seat belt usage among rural high school students.

    Objective Inattention to the roadway, including cell phone use while driving (cell phone calls, sending and reading texts, mobile app use and internet use), is a critical problem for teen drivers and increases risk for crashes. Effective behavioral interventions for teens are needed in order to decrease teen driver inattention related to cell phone use while driving. However, teens’ perceptions of mobile device use while driving is a necessary component for theoretically driven behavior change interventions. The purpose of this study was to describe teen drivers’ perceptions of cell phone use while driving in order to inform future interventions to reduce risky driving. Methods We conducted seven focus groups with a total of 30 teen drivers, ages 16–18, licensed for ≤1 year in Pennsylvania. The focus group interview guide and analysis were based on the Theory of Planned Behavior, identifying the attitudes, perceived behavioral control, and norms about inattention to the roadway. Directed descriptive content analysis was used to analyze the focus group interviews. All focus groups were coded by two research team members and discrepancies were reconciled. Themes were developed based on the data. Results Teens had a mean age of 17.39 (sd 0.52), mean length of licensure of 173.7 days (sd 109.2; range 4–364), were 50% male and predominately white (90%) and non-Hispanic (97%). From the focus group data, three major themes emerged; (1) Recognizing the danger but still engaging; (2) Considering context; and (3) Formulating safer behaviors that might reduce risk. In spite of recognizing hand-held cell phone use, texting and social media app use are dangerous and distracting while driving, teens and their peers often engage in these behaviors. Teens described how the context of the situation contributed to whether a teen would place or answer a call, write or respond to a text, or use a social media app. Teens identified ways in which they controlled their

    There is no satisfactory therapeutic intervention for neonatal hypoxic-ischemic (HI) encephalopathy. Progesterone is known to be effective in treating traumatic brain injury in adult animals but its effects in neonatal brains have not been reported. Brain injuries were induced by a unilateral common carotid artery ligation plus hypoxia exposure. Progesterone was administered immediately after hypoxia and daily for 5 days at 8 mg/kg, followed by a tapered dose for two days. At six weeks post-injury, lesion size and inflammatory factors were evaluated. Progesterone-treated, HI-injured male animals, but not females, showed significant long-term tissue protection compared to vehicle, suggesting an important sex difference in neuroprotection. Progesterone-treated, HI-injured male rats had fewer activated microglia in the cortex and hippocampus compared to controls. The rats were tested for neurological reflexes, motor asymmetry, and cognitive performance at multiple time points. The injured animals exhibited few detectable motor deficits, suggesting a high level of age- and injury-related neuroplasticity. There were substantial sex differences on several behavioral tests, indicating that immature males and females should be analyzed separately. Progesterone-treated animals showed modest beneficial effects in both sexes compared to vehicle-treated injured animals. Sham animals given progesterone did not behave differently from vehicle-treated sham animals on any measures. Copyright © 2015 Elsevier B.V. All rights reserved.

    Traumatic brain injury (TBI) is associated with poor neurological outcome, including necrosis and brain edema. In this study, we investigated whether agmatine treatment reduces edema and apoptotic cell death after TBI. TBI was produced by cold injury to the cerebral primary motor cortex of rats. Agmatine was administered 30 min after injury and once daily until the end of the experiment. Animals were sacrificed for analysis at 1, 2, or 7 days after the injury. Various neurological analyses were performed to investigate disruption of the blood-brain barrier (BBB) and neurological dysfunction after TBI. To examine the extent of brain edema after TBI, the expression of aquaporins (AQPs), phosphorylation of mitogen-activated protein kinases (MAPKs), and nuclear translocation of nuclear factor-κB (NF-κB) were investigated. Our findings demonstrated that agmatine treatment significantly reduces brain edema after TBI by suppressing the expression of AQP1, 4, and 9. In addition, agmatine treatment significantly reduced apoptotic cell death by suppressing the phosphorylation of MAPKs and by increasing the nuclear translocation of NF-κB after TBI. These results suggest that agmatine treatment may have therapeutic potential for brain edema and neural cell death in various central nervous system diseases.

    Background The initial nonoperative management (NOM) of blunt splenic injuries in hemodynamically stable patients is common. In soldiers who experience blunt splenic injuries with concomitant severe brain injury while on deployment, however, NOM may put the injured soldier at risk for secondary brain injury from prolonged hypotension. Methods We conducted a decision analysis using a Markov process to evaluate 2 strategies for managing hemodynamically stable patients with blunt splenic injuries and severe brain injury — immediate splenectomy and NOM — in the setting of a field hospital with surgical capability but no angiography capabilities. We considered the base case of a 40-year-old man with a life expectancy of 78 years who experienced blunt trauma resulting in a severe traumatic brain injury and an isolated splenic injury with an estimated failure rate of NOM of 19.6%. The primary outcome measured was life expectancy. We assumed that failure of NOM would occur in the setting of a prolonged casualty evacuation, where surgical capability was not present. Results Immediate splenectomy was the slightly more effective strategy, resulting in a very modest increase in overall survival compared with NOM. Immediate splenectomy yielded a survival benefit of only 0.4 years over NOM. Conclusion In terms of overall survival, we would not recommend splenectomy unless the estimated failure rate of NOM exceeded 20%, which corresponds to an American Association for the Surgery of Trauma grade III splenic injury. For military patients for whom angiography may not be available at the field hospital and who require prolonged evacuation, immediate splenectomy should be considered for grade III–V injuries in the presence of severe brain injury.

    The aim of this study was to discuss secondary traumatic brain injury, the mitochondria and the use of antioxidants as a treatment. One of the leading causes of death globally is traumatic brain injury, affecting individuals in all demographics. Traumatic brain injury is produced by an external blunt force or penetration resulting in alterations in brain function or pathology. Often, with a traumatic brain injury, secondary injury causes additional damage to the brain tissue that can have further impact on recovery and the quality of life. Secondary injury occurs when metabolic and physiologic processes alter after initial injury and includes increased release of toxic free radicals that cause damage to adjacent tissues and can eventually lead to neuronal necrosis. Although antioxidants in the tissues can reduce free radical damage, the magnitude of increased free radicals overwhelms the body's reduced defence mechanisms. Supplementing the body's natural supply of antioxidants, such as coenzyme Q10, can attenuate oxidative damage caused by reactive oxygen species. Discussion paper. Research literature published from 2011-2016 in PubMed, CINAHL and Cochrane. Prompt and accurate assessment of patients with traumatic brain injury by nurses is important to ensure optimal recovery and reduced lasting disability. Thus, it is imperative that nurses be knowledgeable about the secondary injury that occurs after a traumatic brain injury and aware of possible antioxidant treatments. The use of antioxidants has potential to reduce the magnitude of secondary injury in patients who experience a traumatic brain injury. © 2017 John Wiley & Sons Ltd.

    OBJECTIVE Arachnoid cysts (ACs) are congenital lesions bordered by an arachnoid membrane. Researchers have postulated that individuals with an AC demonstrate a higher rate of structural brain injury after trauma. Given the potential neurological consequences of a structural brain injury requiring neurosurgical intervention, the authors sought to perform a systematic review of sport-related structural-brain injury associated with ACs with a corresponding quantitative analysis. METHODS Titles and abstracts were searched systematically across the following databases: PubMed, Embase, CINAHL, and PsycINFO. The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Peer-reviewed case reports, case series, or observational studies that reported a structural brain injury due to a sport or recreational activity (hereafter referred to as sport-related) with an associated AC were included. Patients were excluded if they did not have an AC, suffered a concussion without structural brain injury, or sustained the injury during a non-sport-related activity (e.g., fall, motor vehicle collision). Descriptive statistical analysis and time to presentation data were summarized. Univariate logistic regression models to assess predictors of neurological deficit, open craniotomy, and cystoperitoneal shunt were completed. RESULTS After an initial search of 994 original articles, 52 studies were found that reported 65 cases of sport-related structural brain injury associated with an AC. The median age at presentation was 16 years (range 4-75 years). Headache was the most common presenting symptom (98%), followed by nausea and vomiting in 49%. Thirteen patients (21%) presented with a neurological deficit, most commonly hemiparesis. Open craniotomy was the most common form of treatment (49%). Bur holes and cyst fenestration were performed in 29 (45%) and 31 (48%) patients, respectively. Seven patients (11%) received

  3. Relationship between changes of N-methyl-D-aspartate receptor activity and brain edema after brain injury in rats

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    Objective: To investigate the relationship between the changes of N-methyl-D-aspartate (NMDA) receptor activity and brain edema after injury in rats.   Methods: The brain injury models were made by using a free-falling body. The treatment model was induced by means of injecting AP5 into lateral ventricle before brain injury; water contents in brain cortex were measured with dry-wet method; and NMDA receptor activity was detected with a radio ligand binding assay.   Results: The water contents began to increase at 30 minutes and reached the peak at 6 hours after brain injury. The maximal binding (Bmax) of NMDA receptor increased significantly at 15 minutes and reached the peak at 30 minutes, then decreased gradually and had the lowest value 6 hours after brain injury. Followed the treatment with AP5, NMDA receptor activity in the injured brain showed a normal value; and the water contents were lower than that of AP5-free injury group 24 hours after brain injury.   Conclusions: It suggests that excessive activation of NMDA receptor may be one of the most important factors to induce the secondary cerebral impairments, and AP5 may protect the brain from edema after brain injury.

    Visual and visual-perceptual impairments occur frequently with traumatic brain injury (TBI) and influence occupational performance. This systematic review examined the effectiveness of interventions within the scope of occupational therapy to improve occupational performance for adults with visual and visual-perceptual impairments as a result of TBI. Medline, PsycINFO, CINAHL, OTseeker, and the Cochrane Database of Systematic Reviews were searched, and 66 full text articles were reviewed. Sixteen articles were included in the review. Strong evidence supports the use of scanning, limited evidence supports the use of adaptive strategies, and mixed evidence supports the use of cognitive interventions to improve occupational performance for adults with TBI. Evidence related to vision therapy varies on the basis of the specific intervention implemented. Although the strength of the research varied, implications are discussed for practice, education, and research. Copyright © 2016 by the American Occupational Therapy Association, Inc.

    To describe and compare pre- and post-injury leisure activities of individuals receiving brain injury rehabilitation and explore levels of leisure participation and satisfaction. Cross-sectional descriptive study incorporating a survey of current and past leisure activities. Questionnaires were completed by 40 individuals with an acquired brain injury receiving inpatient or outpatient rehabilitation. Shortened Version of the Nottingham Leisure Questionnaire and Changes in Leisure Questionnaire (developed for this study). Leisure participation declined following injury, particularly in social leisure activities. Pre-injury activities with high rates of discontinued or decreased participation were driving, going to pubs and parties, do-it-yourself activities and attending sports events. Inpatient participants generally attributed decreased participation to the hospital environment, whereas outpatient participants reported this predominantly as a result of disability. Post-injury levels of perceived leisure satisfaction were significantly lower for the inpatient group compared to pre-injury, but not for the outpatient group. Uptake of some new leisure activities was reported post-injury, however not at the rate to which participation declined. Leisure participation decreases during brain injury rehabilitation compared to pre-injury levels. Re-engagement in relevant, age-appropriate leisure activities needs to be addressed during rehabilitation to improve participation in this domain.

    To assess the role of brain networks in emotion regulation and post-traumatic complaints in the sub-acute phase after non-complicated mild traumatic brain injury (mTBI). Fifty-four patients with mTBI (34 with and 20 without complaints) and 20 healthy controls (group-matched for age, sex, education, and handedness) were included. Resting-state fMRI was performed at four weeks post-injury. Static and dynamic functional connectivity were studied within and between the default mode, executive (frontoparietal and bilateral frontal network), and salience network. The hospital anxiety and depression scale (HADS) was used to measure anxiety (HADS-A) and depression (HADS-D). Regarding within-network functional connectivity, none of the selected brain networks were different between groups. Regarding between-network interactions, patients with complaints exhibited lower functional connectivity between the bilateral frontal and salience network compared to patients without complaints. In the total patient group, higher HADS-D scores were related to lower functional connectivity between the bilateral frontal network and both the right frontoparietal and salience network, and to higher connectivity between the right frontoparietal and salience network. Furthermore, whereas higher HADS-D scores were associated with lower connectivity within the parietal midline areas of the bilateral frontal network, higher HADS-A scores were related to lower connectivity within medial prefrontal areas of the bilateral frontal network. Functional interactions of the executive and salience networks were related to emotion regulation and complaints after mTBI, with a key role for the bilateral frontal network. These findings may have implications for future studies on the effect of psychological interventions. © 2016 Wiley Periodicals, Inc.

    Despite the availability of evidence-based guidelines for the management of mild traumatic brain injury in the emergency department (ED), variations in practice exist. Interventions designed to implement recommended behaviours can reduce this variation. Using theory to inform intervention development is advocated; however, there is no consensus on how to select or apply theory. Integrative theoretical frameworks, based on syntheses of theories and theoretical constructs relevant to implementation, have the potential to assist in the intervention development process. This paper describes the process of applying two theoretical frameworks to investigate the factors influencing recommended behaviours and the choice of behaviour change techniques and modes of delivery for an implementation intervention. A stepped approach was followed: (i) identification of locally applicable and actionable evidence-based recommendations as targets for change, (ii) selection and use of two theoretical frameworks for identifying barriers to and enablers of change (Theoretical Domains Framework and Model of Diffusion of Innovations in Service Organisations) and (iii) identification and operationalisation of intervention components (behaviour change techniques and modes of delivery) to address the barriers and enhance the enablers, informed by theory, evidence and feasibility/acceptability considerations. We illustrate this process in relation to one recommendation, prospective assessment of post-traumatic amnesia (PTA) by ED staff using a validated tool. Four recommendations for managing mild traumatic brain injury were targeted with the intervention. The intervention targeting the PTA recommendation consisted of 14 behaviour change techniques and addressed 6 theoretical domains and 5 organisational domains. The mode of delivery was informed by six Cochrane reviews. It was delivered via five intervention components : (i) local stakeholder meetings, (ii) identification of local opinion

    Construction workers are frequently exposed to various types of injury-inducing hazards. There are a number of injury prevention interventions, yet their effectiveness is uncertain. To assess the effects of interventions for preventing injuries in construction workers. We searched the Cochrane Injuries Group's specialised register, CENTRAL (issue 3), MEDLINE, Embase and PsycINFO up to April 2017. The searches were not restricted by language or publication status. We also handsearched the reference lists of relevant papers and reviews. Randomised controlled trials, controlled before-after (CBA) studies and interrupted time-series (ITS) of all types of interventions for preventing fatal and non-fatal injuries among workers at construction sites. Two review authors independently selected studies, extracted data and assessed their risk of bias. For ITS studies, we re-analysed the studies and used an initial effect, measured as the change in injury rate in the year after the intervention, as well as a sustained effect, measured as the change in time trend before and after the intervention. Seventeen studies (14 ITS and 3 CBA studies) met the inclusion criteria in this updated version of the review. The ITS studies evaluated the effects of: introducing or changing regulations that laid down safety and health requirements for the construction sites (nine studies), a safety campaign (two studies), a drug-free workplace programme (one study), a training programme (one study), and safety inspections (one study) on fatal and non-fatal occupational injuries. One CBA study evaluated the introduction of occupational health services such as risk assessment and health surveillance, one evaluated a training programme and one evaluated the effect of a subsidy for upgrading to safer scaffoldings. The overall risk of bias of most of the included studies was high, as it was uncertain for the ITS studies whether the intervention was independent from other changes and thus could be

    Full Text Available Objective: To increase teen seat belt use among drivers at a rural high school by implementing the Drive Alive Pilot Program (DAPP, a theory-driven intervention built on highway safety best practices.Methods: The first component of the program was 20 observational teen seat belt surveys conducted by volunteer students in a high school parking lot over a 38-month period before and after the month-long intervention. The survey results were published in the newspaper. The second component was the use of incentives, such as gift cards, to promote teen seat belt use. The third component involved disincentives, such as increased police patrol and school policies. The fourth component was a programmatic intervention that focused on education and media coverage of the DAPP program.Results: Eleven pre-intervention surveys and nine post-intervention surveys were conducted before and after the intervention. The pre- and post-intervention seat belt usage showed significant differences (p<0.0001. The average pre-intervention seat belt usage rate was 51.2%, while the average post-intervention rate was 74.5%. This represents a percentage point increase of 23.3 in seat belt use after the DAPP intervention.Conclusion: Based on seat belt observational surveys, the DAPP was effective in increasing seat belt use among rural high school teenagers. Utilizing a theory-based program that builds on existing best practices can increase the observed seat belt usage among rural high school students. [West J Emerg Med. 2010; 11(3: 280-283.

  13. Mild Traumatic Brain Injury: Lessons Learned from Clinical, Sports, and Combat Concussions

    2012-01-01

    Full Text Available Over the past forty years, a tremendous amount of information has been gained on the mechanisms and consequences of mild traumatic brain injuries. Using sports as a laboratory to study this phenomenon, a natural recovery curve emerged, along with standards for managing concussions and returning athletes back to play. Although advances have been made in this area, investigation into recovery and return to play continues. With the increase in combat-related traumatic brain injuries in the military setting, lessons learned from sports concussion research are being applied by the Department of Defense to the assessment of blast concussions and return to duty decision making. Concussion management and treatment for military personnel can be complicated by additional combat related stressors not present in the civilian environment. Cognitive behavioral therapy is one of the interventions that has been successful in treating symptoms of postconcussion syndrome. While we are beginning to have an understanding of the impact of multiple concussions and subconcussive blows in the sports world, much is still unknown about the impact of multiple blast injuries.

    To characterize the effects of caregiver mental health and coping strategies on interactions with an injured adolescent acutely after traumatic brain injury (TBI). Multi-site, cross-sectional study. Outpatient setting of 3 tertiary pediatric hospitals and 2 tertiary general medical centers. Adolescents (N = 125) aged 12-17 years, 1-6 months after being hospitalized with complicated mild to severe TBI. Data were collected as part of a multi-site clinical trial of family problem-solving therapy after TBI. Multiple regression analyses were used to examine the relationship of caregiver and environmental characteristics to the dimensions of effective communication, warmth, and negativity during caregiver-adolescent problem-solving discussions. Adolescent and caregiver interactions, as measured by the Iowa Family Interaction Rating Scales. Caregivers who utilized problem-focused coping strategies were rated as having higher levels of effective communication (P teen interactions. Problem-focused coping strategies are associated with higher levels of effective communication and lower levels of caregiver negativity during the initial months after adolescent TBI, suggesting that effective caregiver coping may facilitate better caregiver-adolescent interactions after TBI.

    This case study describes a task-specific training program for gait walking and functional recovery in a young man with severe chronic traumatic brain injury. The individual was a 26-year-old man 4 years post-traumatic brain injury with severe motor impairments who had not walked outside of therapy since his injury. He had received extensive gait training prior to initiation of services. His goal was to recover the ability to walk. The primary focus of the interventions was the restoration of walking. A variety of interventions were used, including locomotor treadmill training, electrical stimulation, orthoses, and specialized assistive devices. A total of 79 treatments were delivered over a period of 62 weeks. At the conclusion of therapy, the client was able to walk independently with a gait trainer for approximately 1km (over 3000 ft) and walked in the community with the assistance of his mother using a rocker bottom crutch for distances of 100m (330 ft). Specific interventions were intentionally selected in the development of the treatment plan. The program emphasized structured practice of the salient task, that is, walking, with adequate intensity and frequency. Given the chronicity of this individual's injury, the magnitude of his functional improvements was unexpected.Video Abstract available for additional insights from the Authors (see Video, Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A175).

    Full Text Available The purpose of this study was to compare the effect of PbtO2-guided therapy with traditional intracranial pressure- (ICP- guided treatment on the management of cerebral variables, therapeutic interventions, survival rates, and neurological outcomes of moderate and severe traumatic brain injury (TBI patients. From 2009 to 2010, TBI patients with a Glasgow coma scale 20 mmHg, and 27 patients were treated with ICP-guided therapy (ICP 60 mmHg in the neurosurgical intensive care unit (NICU; demographic characteristics were similar across groups. The survival rate in the PbtO2-guided group was also significantly increased at 3 and 6 months after injury. Moreover, there was a significant correlation between the PbtO2 signal and Glasgow outcome scale-extended in patients from 1 to 6 months after injury. This finding demonstrates that therapy directed by PbtO2 monitoring is valuable for the treatment of patients with moderate and severe TBI and that increasing PaO2 to 150 mmHg may be efficacious for preventing cerebral hypoxic events after brain trauma.

    Objectives We reviewed the literature on interventions that aimed to improve hospital-to-school reintegration for children and youth with acquired brain injury (ABI). ABI is the leading cause of disability among children and youth. A successful hospital-to-school reintegration process is essential to the rehabilitative process. However, little is known about the effective components of of such interventions. Methods and findings Our research team conducted a systematic review, completing comprehensive searches of seven databases and selected reference lists for relevant articles published in a peer-reviewed journal between 1989 and June 2014. We selected articles for inclusion that report on studies involving: a clinical population with ABI; sample had an average age of 20 years or younger; an intentional structured intervention affecting hospital-to-school transitions or related components; an experimental design; and a statistically evaluated health outcome. Two independent reviewers applied our inclusion criteria, extracted data, and rated study quality. A meta-analysis was not feasible due to the heterogeneity of the studies reported. Of the 6933 articles identified in our initial search, 17 articles (reporting on 350 preadolescents and adolescents, aged 4–19, (average age 11.5 years, SD: 2.21) met our inclusion criteria. They reported on interventions varying in number of sessions (one to 119) and session length (20 minutes to 4 hours). The majority of interventions involved multiple one-to-one sessions conducted by a trained clinician or educator, homework activities, and parental involvement. The interventions were delivered through different settings and media, including hospitals, schools, and online. Although outcomes varied (with effect sizes ranging from small to large), 14 of the articles reported at least one significant improvement in cognitive, social, psychological, or behavioral functioning or knowledge of ABI. Conclusions Cognitive, behavioral

    Objective: To investigate the value of low-field MIR in diagnosis of acute CO poisoning brain injury. Methods: The brain MIR and clinical data of 110 patients with acute CO poisoning brain injury confirmed by clinical examination were retrospectively analyzed. Results: Long T1 and T2 signal intensity was showed on MRI in cerebral hemispheres and globus pallidus symmetrically. There were three basic types of MIR manifestations, white matter of brain type, globus pallidus type and brain mixed type. Conclusions: MRI could be used for confirming the degree and range of acute CO poisoning brain injury. It has important clinical value in the diagnosis, staging and prognosis of patients with acute CO poisoning brain injury. (authors)

    Although environmental enrichment has been shown to improve functional and histologic outcomes in pre-clinical moderate-to-severe traumatic brain injury (TBI), there are a paucity of pre-clinical data regarding enrichment strategies in the setting of repetitive mild traumatic brain injury (rmTBI). Given the vast numbers of athletes and those in the military who sustain rmTBI, the mounting evidence of the long-term and progressive sequelae of rmTBI, and the lack of targeted therapies to mitigate these sequelae, successful enrichment interventions in rmTBI could have large public health significance. Here, we evaluated enrichment strategies in an established pre-clinical rmTBI model. Seventy-one male C57BL/6 mice were randomized to two different housing conditions, environmental enrichment (EE) or normal condition (NC), then subjected to rmTBI injury (seven injuries in 9 days) or sham injury (anesthesia only). Functional outcomes in all four groups (NC-TBI, EE-TBI, NC-sham, and EE-sham) were assessed by motor, exploratory/anxiety, and mnemonic behavioral tests. At the synaptic level, N-methyl d-aspartate receptor (NMDAR) subunit expression of phosphorylated glutamate receptor 1 (GluR1), phosphorylated Ca 2+ /calmodulin-dependent protein kinase II (CaMKII), and calpain were evaluated by western blot. Compared to injured NC-TBI mice, EE-TBI mice had improved memory and decreased anxiety and exploratory activity post-injury. Treatment with enrichment also corresponded to normal NMDAR subunit expression, decreased GluR1 phosphorylation, decreased phosphorylated CaMKII, and normal calpain expression post-rmTBI. These data suggest that enrichment strategies may improve functional outcomes and mitigate synaptic changes post-rmTBI. Given that enrichment strategies are feasible in the clinical setting, particularly for athletes and soldiers for whom the risk of repetitive injury is greatest, these data suggest that clinical trials may be warranted.

    The absence of a father figure has been linked to very poor developmental outcomes for the child. During incarceration, there are limited opportunities for visitation between fathers and their children. The Baby Elmo Program provides incarcerated teen fathers with parenting training and visitation with their children with the stated goal of enhancing father-child interactional quality. Forty-one incarcerated teen fathers and their infants ranging from 1 to 15 months of age participated in the present study. During individual sessions, a trained facilitator prepared fathers for visits with their children by introducing key concepts such as following the child's lead, using developmentally appropriate media to illustrate those concepts. After each training session, the incarcerated teen father interacted with his infant and the visit was video recorded. Analysis of the visit sessions focused on father's time use on different activities, the quality of father-infant interactions, and father's integration of target skills introduced in the intervention. The time-use analysis revealed that time use changed as a function of infant age. Growth linear modeling indicated that there were significant positive increases in the amount of parent support and infant engagement as a function of the number of sessions. Follow-up analyses indicated that changes between specific sessions mapped onto the target skills discussed during specific training sessions. This study's preliminary findings suggest that an intervention integrating visitation and appropriate media may be effective for incarcerated teen fathers. Due to the lack of a randomized control group, the present findings are exploratory and are discussed with a focus on further program development.

    Full Text Available Noninvasive rehabilitation strategies for children with unilateral cerebral palsy are routinely used to improve hand motor function, activity, and participation. Nevertheless, the studies exploring their effects on brain structure and function are very scarce. Recently, structural neuroplasticity was demonstrated in adult poststroke patients, in response to neurorehabilitation. Our purpose is to review current evidence on the effects of noninvasive intervention strategies on brain structure or function, in children with unilateral cerebral palsy. The main literature databases were searched up to October 2013. We included studies where the effects of upper limb training were evaluated at neurofunctional and/or neurostructural levels. Only seven studies met our selection criteria; selected studies were case series, six using the intervention of the constraint-induced movement therapy (CIMT and one used virtual reality therapy (VR. CIMT and VR seem to produce measurable neuroplastic changes in sensorimotor cortex associated with enhancement of motor skills in the affected limb. However, the level of evidence is limited, due to methodological weaknesses and small sample sizes of available studies. Well-designed and larger experimental studies, in particular RCTs, are needed to strengthen the generalizability of the findings and to better understand the mechanism of intervention-related brain plasticity in children with brain injury.

  8. Traumatic Brain Injuries during Development: Implications for Alcohol Abuse

    Directory of Open Access Journals (Sweden)

    Zachary M. Weil

    2017-07-01

    Full Text Available Traumatic brain injuries are strongly related to alcohol intoxication as by some estimates half or more of all brain injuries involve at least one intoxicated individual. Additionally, there is mounting evidence that traumatic brain injuries can themselves serve as independent risk factors for the development of alcohol use disorders, particularly when injury occurs during juvenile or adolescent development. Here, we will review the epidemiological and experimental evidence for this phenomenon and discuss potential psychosocial mediators including attenuation of negative affect and impaired decision making as well as neurochemical mediators including disruption in the glutamatergic, GABAergic, and dopaminergic signaling pathways and increases in inflammation.

  9. The Importance of Early Brain Injury after Subarachnoid Hemorrhage

    Aneurysmal subarachnoid hemorrhage (aSAH) is a medical emergency that accounts for 5% of all stroke cases. Individuals affected are typically in the prime of their lives (mean age 50 years). Approximately 12% of patients die before receiving medical attention, 33% within 48 hours and 50% within 30 days of aSAH. Of the survivors 50% suffer from permanent disability with an estimated lifetime cost more than double that of an ischemic stroke. Traditionally, spasm that develops in large cerebral arteries 3-7 days after aneurysm rupture is considered the most important determinant of brain injury and outcome after aSAH. However, recent studies show that prevention of delayed vasospasm does not improve outcome in aSAH patients. This finding has finally brought in focus the influence of early brain injury on outcome of aSAH. A substantial amount of evidence indicates that brain injury begins at the aneurysm rupture, evolves with time and plays an important role in patients’ outcome. In this manuscript we review early brain injury after aSAH. Due to the early nature, most of the information on this injury comes from animals and few only from autopsy of patients who died within days after aSAH. Consequently, we began with a review of animal models of early brain injury, next we review the mechanisms of brain injury according to the sequence of their temporal appearance and finally we discuss the failure of clinical translation of therapies successful in animal models of aSAH.

    Posttraumatic seizures are a common complication of traumatic brain injury. Posttraumatic epilepsy accounts for 20% of symptomatic epilepsy in the general population and 5% of all epilepsy. Early posttraumatic seizures occur in more than 20% of patients in the intensive care unit and are associated with secondary brain injury and worse patient outcomes. Most posttraumatic seizures are nonconvulsive and therefore continuous electroencephalography monitoring should be the standard of care for patients with moderate or severe brain injury. The literature shows that posttraumatic seizures result in secondary brain injury caused by increased intracranial pressure, cerebral edema and metabolic crisis. Copyright © 2016 Elsevier Inc.

    Full Text Available Traumatic brain injury (TBI and substance use disorders (SUDs frequently co-occur. Individuals with histories of alcohol or other drug use are at greater risk for sustaining TBI, and individuals with TBI frequently misuse substances before and after injury. Further, a growing body of literature supports the relationship between comorbid histories of mild TBI (mTBI and SUDs and negative outcomes. Alcohol and other drug use are strongly associated with risk taking. Disinhibition, impaired executive function, and/or impulsivity as a result of mTBI also contribute to an individual’s proclivity towards risk-taking. Risk-taking behavior may therefore, be a direct result of SUD and/or history of mTBI, and risky behaviors may predispose individuals for subsequent injury or continued use of substances. Based on these findings, evaluation of risk-taking behavior associated with the co-occurrence of SUD and mTBI should be a standard clinical practice. Interventions aimed at reducing risky behavior among members of this population may assist in decreasing negative outcomes. A novel intervention (Substance Use and Traumatic Brain Injury Risk Reduction and Prevention (STRRP for reducing and preventing risky behaviors among individuals with co-occurring mTBI and SUD is presented. Areas for further research are discussed.

    Traumatic brain injury (TBI) has complex effects on the gastrointestinal tract that are associated with TBI-related morbidity and mortality. We examined changes in mucosal barrier properties and enteric glial cell response in the gut after experimental TBI in mice, as well as effects of the enteric pathogen Citrobacter rodentium (Cr) on both gut and brain after injury. Moderate-level TBI was induced in C57BL/6mice by controlled cortical impact (CCI). Mucosal barrier function was assessed by transepithelial resistance, fluorescent-labelled dextran flux, and quantification of tight junction proteins. Enteric glial cell number and activation were measured by Sox10 expression and GFAP reactivity, respectively. Separate groups of mice were challenged with Cr infection during the chronic phase of TBI, and host immune response, barrier integrity, enteric glial cell reactivity, and progression of brain injury and inflammation were assessed. Chronic CCI induced changes in colon morphology, including increased mucosal depth and smooth muscle thickening. At day 28 post-CCI, increased paracellular permeability and decreased claudin-1 mRNA and protein expression were observed in the absence of inflammation in the colon. Colonic glial cell GFAP and Sox10 expression were significantly increased 28days after brain injury. Clearance of Cr and upregulation of Th1/Th17 cytokines in the colon were unaffected by CCI; however, colonic paracellular flux and enteric glial cell GFAP expression were significantly increased. Importantly, Cr infection in chronically-injured mice worsened the brain lesion injury and increased astrocyte- and microglial-mediated inflammation. These experimental studies demonstrate chronic and bidirectional brain-gut interactions after TBI, which may negatively impact late outcomes after brain injury. Copyright © 2017 Elsevier Inc.

    Few people with chronic moderate-to-severe brain injury are following recommended physical activity guidelines. Investigate effects of planned, systematic physical activity while cultivating social and emotional well-being of people with chronic moderate-to-severe brain injury. Moderate-to-intensive physical activity would be associated with improvements in impairment and activity limitation measures (endurance, mobility, gait speed) immediately post-intervention and six weeks later (study week 12). The intervention was a single group pre-/post-intervention study with 14 people with chronic moderate-to-severe brain injury who live in brain injury group homes and exercised 60-90 min, 3 days per week for 6 weeks at a maximum heart rate of 50-80%. Pre-post measures (administered weeks 0, 6 and 12) were the 6 Minute Walk Test, High-level Mobility Assessment Tool and 10 Meter Walk Test. The qualitative component used a brief survey and semi-structured interview guide with participants, family members, and staff. Following program completion, post-intervention group changes were noted on all outcome measures and greater than minimal detectable change for people with brain injury. Three transitioned from low to high ambulatory status and maintained this change at 12 weeks. During interviews, participants agreed the program was stimulating. More than eighty percent liked working out in a group and felt better being active. Program impact included physical, cognitive and social/emotional aspects. Social aspects (group format, trainers) were highly motivating and supported by residents, family, and staff. Investments in transportation and recruiting and training interns to assist participants are critical to program sustainability and expansion. Copyright © 2017 Elsevier Inc. All rights reserved.

    Several studies have shown misconceptions about brain injury in different populations. The aim of this study was to assess the knowledge and perceptions about brain injury of family members of neurosurgical patients in our hospital. The participants (n=81) were relatives of patients admitted to the neurosurgery department between February and August 2016. They voluntarily completed a 19-item true-false format survey about brain injury based on a translation of other questionnaires used in previous studies from other countries (USA, Canada, UK, Ireland and New Zealand). Also, some sociodemographic data were collected (age, sex, education level and the patient's pathology). Data analysis was developed through graphical modelling with a regularisation parameter plotted on a network representing the association of the items of the questionnaire from the response pattern of participants. Data analysis showed two conceptual areas with a high rate of wrong answers: behaviour and management of patients, and expectations about acquired brain injury recovery. The results obtained in this study would enable us to objectify misconceptions about acquired brain injury in patients' relatives attended in the neurosurgery department. This lack of knowledge could be a great obstacle in patients' recovery process. Therefore, we suggest placing the emphasis on the provision of information on brain injury to patients' families, especially with regard to its symptoms and course of development.

    2000-01-01

    Background: The purpose of this manuscript is to present the findings in the largest series of SPECT brain perfusion imaging reported to date for mild or moderate traumatic brain injury. PATIENTS AND METHODS: This is a retrospective evaluation of 228 SPECT brain perfusion-imaging studies of patients who suffered mild or moderate traumatic brain injury with or without loss of consciousness (LOC). All patients had no past medical history of previous brain trauma, neurological, or psychiatric diseases, HIV, alcohol or drug abuse. The patient population included 135 males and 93 females. The ages ranged from 11-88 years (mean 40.8). The most common complaints were characteristic of the postconcussion syndrome: headaches 139/228 (61%); dizziness 61/228 (27%); and memory problems 63/228 (28%). LOC status was reported to be positive in 121/228 (53%), negative in 41/228 (18%), and unknown for 63/228 (28%). RESULTS: Normal studies accounted for 52/228 (23%). For abnormal studies (176/228 or 77%) the findings were as follows: basal ganglia hypoperfusion 338 lesions (55.2%); frontal lobe hypoperfusion 146 (23.8%); temporal lobes hypoperfusion 80 (13%); parietal lobes hypoperfusion 20 (3.7%); insular and or occipital lobes hypoperfusion 28 (4.6%). Patients' symptoms correlated with the SPECT brain perfusion findings. The SPECT BPI studies in 122/228 (54%) were done early within 3 months of the date of the accident, and for the remainder, 106/228 (46%) over 3 months and less than 3 years from the date of the injury. In early imaging, 382 lesions were detected; in 92 patients (average 4.2 lesions per study) imaging after 3 months detected 230 lesions: in 84 patients (average 2.7 lesions per study). CONCLUSIONS: Basal ganglia hypoperfusion is the most common abnormality following mild or moderate traumatic brain injury (p = 0.006), and is more common in patients complaining of memory problem (p = 0.0005) and dizziness (p = 0.003).

    Full Text Available Objective: The objective of this study was to determine the speed of bony union and the serum levels of biomarkers in the setting of bone fractures combined with brain injury. Materials and Methods: In this study, Sprague–Dawley rats were randomized into four groups: sham, brain injury, bone fracture, and bone fracture plus brain injury groups. The serum levels of biochemical markers, namely, nerve growth factor (NGF, Wnt-3a, Dickkopf-related protein-1, receptor-activator of NF-κB ligand, and adrenocorticotropic hormone (ACTH, were measured on the days 1, 3, 7, and 14 following injury. Bony union was evaluated using radiographs every week for 6 weeks. Results: Compared with the brain injury group and bone fracture group, the radiographs of the bone fracture plus brain injury group revealed enhanced callus formations in week 2. From week 3, the callus formation did not differ significantly among the groups. The serum levels of the biomarkers varied at different time points. The serum levels of NGF on days 1 and 3, Wnt-3a on days 3 and 14, and ACTH on days 1, 3, and 7 were significantly higher in the bone fracture plus brain injury group than in the bone fracture group. Conclusions: Brain injury increases callus formation in simultaneous bone fracture. Considering the time point, early NGF, Wnt-3a, and ACTH elevation might be associated with early callus formation enhancement. The results indicate that these brain injury-induced biomarkers might play crucial role in accelerating bone healing.

    The large contribution of inexperience to the high crash rate of newly licensed teens suggests that they enter licensure with insufficient skills. In a prior analysis, we found moderate support for a direct effect of a web-based intervention, the TeenDrivingPlan (TDP), on teens' driving performance. The purpose of the present study was to identify the mechanisms by which TDP may be effective and to extend our understanding of how teens learn to drive. A randomized controlled trial conducted with teen permit holders and parent supervisors (N = 151 dyads) was used to determine if the effect of TDP on driver performance operated through five hypothesized mediators: (1) parent-perceived social support; (2) teen-perceived social support; (3) parent engagement; (4) practice quantity; and (5) practice diversity. Certified driving evaluators, blinded to teens' treatment allocation, assessed teens' driving performance 24 weeks after enrollment. Mediator variables were assessed on self-report surveys administered periodically over the study period. Exposure to TDP increased teen-perceived social support, parent engagement, and practice diversity. Both greater practice quantity and diversity were associated with better driving performance, but only practice diversity mediated the relationship between TDP and driver performance. Practice diversity is feasible to change and increases teens' likelihood of completing a rigorous on-road driving assessment just before licensure. Future research should continue to identify mechanisms that diversify practice driving, explore complementary ways to help families optimize the time they spend on practice driving, and evaluate the long-term effectiveness of TDP.

    We examined medical, educational and social risks to children of teen mothers and children of nonadolescent mothers with a history of teen birth (prior teen mothers) and considered these risks at both the individual and societal level. A population-based, retrospective cohort study tracked outcomes through young adulthood for children born in Manitoba, Canada (n = 32 179). chi(2) and logistic regression analyses examined risk of childhood death or hospitalization, failure to graduate high school, intervention by child protective services, becoming a teen mother, and welfare receipt as a young adult. For children of both teen and prior teen mothers, adjusted likelihoods of death during infancy, school-aged years, and adolescence were more than 2-fold higher than for other children. Risks for hospitalization, high hospital use, academic failure, and poor social outcomes were also substantially higher. At a societal level, only 16.5% of cohort children were born to teen and prior teen mothers. However, these children accounted for 27% of first-year hospitalizations, 34% of deaths (birth to 17 years), 30% of failures to graduate high school, 51% in foster care, 44% on welfare as young adults, and 56% of next-generation young teen mothers. Children of prior teen mothers had increased risks for poor health and for educational and social outcomes nearly equal to those seen in children of teen mothers. Combined, these relatively few children experienced a large share of the negative outcomes occurring among young people. Our results suggest the need to expand the definition of risk associated with adolescent motherhood and target their children for enhanced medical and social services.

    To assess the role of 1H MRS in the detection of changes in cerebral metabolite levels in pyramidal tracts after mild traumatic brain injury (MTBI) and to compare metabolite alterations to the clinical status (Glasgow Coma Scale). Study group consisted of 25 patients after mild traumatic brain injury, with a score of 11 to 15 in GCS. The MR studies were performed with a 1.5 T scanner. The results of spectra approximation (presented as metabolite ratios: NAA/Cr, NAA/Cho, Cho/Cr, lac/Cr, lip/Cr, Glx/Cr) were subjected to statistical analysis. MR spectra were recorded from a normal-appearing brain region: internal capsules and cerebral peduncles. Spectra from traumatic patients were compared with a control group including 34 healthy volunteers recorded with the same techniques. The statistical analysis revealed significant differences between the data obtained from various brain regions of the same patients after an MTBI and between the study and the control group. Proton MR spectroscopy detects changes in cerebral metabolite levels in apparently normal regions. In pyramidal tracts (internal capsules, cerebral peduncles), we noticed a significant reduction of NAA /Cho, lip/Cr, lac/Cr and Glx/Cr. In patients with mild brain injury, we can detect some metabolite abnormalities in normal-appearing brain structures. Proton MRS is a very useful tool for evaluation of major changes in metabolite levels in pyramidal tracts after mild traumatic brain injury

    Full Text Available Only a few studies have considered changes in brain structures other than sensory and motor cortex after spinal cord injury, although cognitive impairments have been reported in these patients. Spinal cord injury results in chronic brain neuroinflammation with consequent neurodegeneration and cognitive decline in rodents. Regarding the hippocampus, neurogenesis is reduced and reactive gliosis increased. These long-term abnormalities could explain behavioral impairments exhibited in humans patients suffering from spinal cord trauma.

    The Brain Injury Cognitive Screen (BICS) was developed as an in-service cognitive assessment battery for acquired brain injury patients entering community rehabilitation. The BICS focuses on domains that are particularly compromised following TBI, and provides a broader and more detailed assessment of executive function, attention and information processing than comparable screening assessments. The BICS also includes brief assessments of perception, naming, and construction, which were predicted to be more sensitive to impairments following non-traumatic brain injury. The studies reported here examine preliminary evidence for its validity in post-acute rehabilitation. In Study 1, TBI patients completed the BICS and were compared with matched controls. Patients with focal lesions and matched controls were compared in Study 2. Study 3 examined demographic effects in a sample of normative data. TBI and focal lesion patients obtained significantly lower composite memory, executive function and attention and information processing BICS scores than healthy controls. Injury severity effects were also obtained. Logistic regression analyses indicated that each group of BICS memory, executive function and attention measures reliably differentiated TBI and focal lesion participants from controls. Design Recall, Prospective Memory, Verbal Fluency, and Visual Search test scores showed significant independent regression effects. Other subtest measures showed evidence of sensitivity to brain injury. The study provides preliminary evidence of the BICS' sensitivity to cognitive impairment caused by acquired brain injury, and its potential clinical utility as a cognitive screen. Further validation based on a revised version of the BICS and more normative data are required.

    While childhood agricultural injury has long been recognized as an important public health issue, most research has focused on family farms and there have not been many interventions targeting hired youth. This study evaluated the impact of a high school English as a Second Language (ESL) curriculum, designed to provide teen agricultural workers with the knowledge and tools to protect their health and safety in the fields. Using a quasi-experimental design, the research consisted of two intervention groups and a comparison group, and included over 2,000 students from communities that lead California in agricultural production. The research findings revealed that the curriculum had significant impact in terms of increases in knowledge and attitudes, and nearly half of those interviewed after a summer of working in the fields reported implementing new behaviors to protect their health and safety. The curriculum also had extended effects in the broader community, as the majority of students reported sharing the new information with others. The study found that a school-based ESL curriculum is an effective intervention to reach and educate teen farm workers and that ESL classes can serve as a much-needed access point for young farm workers.

    Full Text Available BACKGROUND: Patients with traumatic brain injury (TBI usually have mood and anxiety symptoms secondary to their brain injury. Exercise may be a cost-effective intervention for the regulation of the affective responses of this population. However, there are no studies evaluating the effects of exercise or the optimal intensity of exercise for this clinical group. METHODS: Twelve male patients with moderate or severe TBI [mean age of 31.83 and SD of 9.53] and 12 age- and gender-matched healthy volunteers [mean age of 30.58 and SD of 9.53] participated in two sessions of exercise of high and moderate intensity. Anxiety and mood was evaluated, and subjective assessment of experience pre- and post-exercise was assessed. A mixed between and within-subjects GLM analysis was conducted to compare groups [TBI, control] over condition [baseline, session 1, session 2] allowing for group by condition interaction to be determined. Planned comparisons were also conducted to test study hypotheses.RESULTS: Although no group by condition interaction was observed, planned comparisons indicated that baseline differences between patients and controls in anxiety (Cohens’ d=1.80, tension (d=1.31, depression (d=1.18, anger (d=1.08, confusion (d=1.70, psychological distress (d=1.28 and physical symptoms (d=1.42 disappear after one session of exercise, independently of the intensity of exercise. CONCLUSIONS: A single-section of exercise, regardless of exercise intensity, had a positive effect on the affective responses of patients with TBI both by increasing positive valence feelings and decreasing negative ones. Exercise can be an easily accessible intervention that may alleviate depressive symptoms related to brain injury.

    Recently, the occurrence of a higher brain dysfunction after brain injury has been socially noticed and epidemiological investigations have thus been performed. However, most of these previous investigations tended to be based on populations in a chronic stage after brain trauma. We hypothesized that some patients with a higher brain dysfunction were socially in extreme distress after being discharged from our hospital due to a lack of any follow-up treatment. We investigated this problem to identify possible problems in diagnosing and follow-up for a higher brain dysfunction after blunt traumatic brain injury at a tertiary emergency center. A questionnaire survey was performed for 204 blunt trauma patients who had been admitted during the period from January 2000 thorough December 2003. Clinical examinations were performed for patients suspected of having a higher brain dysfunction based on this questionnaire survey. Three patients had been already diagnosed to have a higher brain dysfunction while other 3 patients were newly diagnosed in this investigation. The newly diagnosed patients discharged from departments other than the neurosurgery department. Computed tomography (CT) was performed in 82% patients (65 patients) to diagnose major brain injury or bone fracture. No magnetic resonance image was performed to detect any minor brain injury in alert patients. Overlooking the occurrence of a higher brain dysfunction may result from an insufficient recognition of higher brain dysfunction and an insufficient sensitivity of the present diagnostic methods available for minor brain injury. An increased awareness regarding the potential of a higher brain dysfunction existing in such patients is therefore needed by the entire medical staff and the general public. (author)

    To investigate the relation between brain ischemia and persistent vegetative state after severe traumatic brain injury. The 66 patients with severe brain injury were divided into two groups: The persistent coma group (coma duration ≥10 d) included 51 patients who had an admission Glasgow Coma Scale (GCS) of 5-8 and were unconscious for more than 10 d. There were 15 patients in the control group, their admission GCS was 5-8, and were unconscious for less than 10 d. The brain areas, including frontal, parietal, temporal, occipital lobes and thalamus, were measured by Single Photon Emission Computed Tomography (SPECT). In the first SPECT scan, multiple areas of cerebral ischemia were documented in all patients in both groups, whereas bilateral thalamic ischemia were presented in all patients in the persistent coma group and were absented in the control group. In the second SPECT scan taken during the period of analepsia, with an indication that unilateral thalamic ischemia were persisted in 28 of 41 patients in persistent coma group(28/41,68.29%). Persistent coma after severe brain injury is associated with bilateral thalamic ischemia.

    Although the negative impact of symptom severity on subjective well-being outcomes has been established among individuals with brain injury, the mediating and protective role that positive human traits might have on this relationship has not been adequately explored. The purpose of this study was to examine the impact of social self-efficacy and disability acceptance on the relationship between symptom severity and life satisfaction among individuals with brain injury. Hierarchical regression analysis and correlation techniques were used to test a hypothesized dual-mediation model of life satisfaction in a sample of 105 adults with acquired brain injury. Results indicated that social self-efficacy and disability acceptance fully mediated the relationship between symptom severity and life satisfaction, lending support for a dual-mediation model with disability acceptance being the strongest contributor. These findings suggest there may be considerable value for rehabilitation providers to develop strengths-based service strategies and/or specialized intervention programs that focus on capitalizing these positive human traits to promote life satisfaction and well-being for clients with brain injury. Implications for clinical practice and future research direction are also discussed.

    Turmeric has been in use since ancient times as a condiment and due to its medicinal properties. Curcumin, the yellow coloring principle in turmeric, is a polyphenolic and a major active constituent. Besides anti-inflammatory, thrombolytic and anti-carcinogenic activities, curcumin also possesses strong antioxidant property. The neuroprotective effects of curcumin were evaluated in a weight drop model of cortical contusion trauma in rat. Male Wistar rats (350-400 g, n=9) were anesthetized with sodium pentobarbital (60 mg/kg i.p.) and subjected to head injury. Five days before injury, animals randomly received an i.p. bolus of either curcumin (50 and 100 mg/kg/day, n=9) or vehicle (n=9). Two weeks after the injury and drug treatment, animals were sacrificed and a series of brain sections, stained with hematoxylin and eosin (H&E) were evaluated for quantitative brain lesion volume. Two weeks after the injury, oxidative stress parameter (malondialdehyde) was also measured in the brain. Curcumin (100 mg/kg) significantly reduced the size of brain injury-induced lesions (Pcurcumin (100 mg/kg). Curcumin treatment significantly improved the neurological status evaluated during 2 weeks after brain injury. The study demonstrates the protective efficacy of curcumin in rat traumatic brain injury model. © 2013 Elsevier Inc. All rights reserved.

    Traumatic spinal cord injury is clinically treated by high doses of methylprednisolone. However, the effect of methylprednisolone on the brain in spinal cord injury patients has been little investigated. This experimental study examined Bcl-2 and Bax protein expression and Nissl staining to evaluate an apoptosis-related intracellular signaling event and final neuron death, respectively. Spinal cord injury produced a significant apoptotic change and cell death not only in the spinal cord but also in the supraventricular cortex and hippocampal cornu ammonis 1 region in the rat brains. The treatment of methylprednisolone increased the Bcl-2/Bax ratio and prevented neuron death for 1-7 days after spinal cord injury. These findings suggest that rats with spinal cord injury show ascending brain injury that could be restricted through methylprednisolone management.

    Several clinical and experimental studies have shown that lung injury occurs shortly after brain damage. The responsible mechanisms involve neurogenic pulmonary edema, inflammation, the harmful action of neurotransmitters, or autonomic system dysfunction. Mechanical ventilation, an essential component of life support in brain-damaged patients (BD), may be an additional traumatic factor to the already injured or susceptible to injury lungs of these patients thus worsening lung injury, in case that non lung protective ventilator settings are applied. Measurement of respiratory mechanics in BD patients, as well as assessment of their evolution during mechanical ventilation, may lead to preclinical lung injury detection early enough, allowing thus the selection of the appropriate ventilator settings to avoid ventilator-induced lung injury. The aim of this review is to explore the mechanical properties of the respiratory system in BD patients along with the underlying mechanisms, and to translate the evidence of animal and clinical studies into therapeutic implications regarding the mechanical ventilation of these critically ill patients.

    Severe traumatic brain injury (sTBI) is a major contributor to long-term disability and a leading cause of death worldwide. Medical management of the sTBI patient, beginning with prehospital triage, is aimed at preventing secondary brain injury. This review discusses prehospital and emergency department management of sTBI, as well as aspects of TBI management in the intensive care unit where advances have been made in the past decade. Areas of emphasis include intracranial pressure management, neuromonitoring, management of paroxysmal sympathetic hyperactivity, neuroprotective strategies, prognostication, and communication with families about goals of care. Where appropriate, differences between the third and fourth editions of the Brain Trauma Foundation guidelines for the management of severe traumatic brain injury are highlighted.

    The risk of sport-related concussion (SRC) has emerged as a major public health concern. In rare instances, sport-related head injuries can be even more severe, such as subdural hemorrhage, epidural hemorrhage, or malignant cerebral edema. Unlike SRCs, sport-related structural brain injury (SRSBI) is rare, may require neurosurgical intervention, and can lead to permanent neurologic deficit or death. Data characterizing SRSBI are limited, and many have recognized the need to better understand these catastrophic brain injuries. The goal of the current series is to describe, in detail, the presentation, management, and outcomes of examples of these rare injuries. During the fall of 2015, three high school football players presented with acute subdural hemorrhages following in-game collisions and were treated at our institution within a span of 2 months. For the 2 athletes who required surgical intervention, a previous SRC was sustained within 4 weeks before the catastrophic event. One year after injury, 2 players have returned to school, though with persistent deficits. One patient remains nonverbal and wheelchair bound. None of the athletes has returned to sports. Acute subdural hemorrhage resultant from an in-game football collision is rare. The temporal proximity of the reported SRSBIs to recent SRCs emphasizes the importance of return-to-play protocols and raises questions regarding the possibility of second impact syndrome. Although epidemiologic conclusions cannot be drawn from this small sample, these cases provide a unique opportunity to demonstrate the presentation, management, and long-term outcomes of SRSBI in American high school football.

    2016-02-01

    The goal of this supplemental issue is to address major knowledge, research, and clinical practice gaps regarding the limited focus on brain injury in girls and women as well as limited analysis of the effect of sex and gender in research on acquired brain injury. Integrating sex and gender in research is recognized as leading to better science and, ultimately, to better clinical practice. A sex and gender analytical approach to rehabilitation research is crucial to understanding traumatic brain injury and improving quality of life outcomes for survivors. Put another way, the lack of focus on sex and gender reduces the rigor of research design, the generalizability of study findings, and the effectiveness of clinical implementation and knowledge dissemination practices. The articles in this supplement examine sex and gender using a variety of methodological approaches and research contexts. Recommendations for future research on acquired brain injury that consciously incorporates sex and gender are made throughout this issue.

    2014-04-01

    Full Text Available Cathepsin B is one of the major lysosomal cysteine proteases involved in neuronal protein catabolism. This cathepsin is released after traumatic injury and increases neuronal death; however, release of cystatin C, a cathepsin inhibitor, appears to be a self-protective brain response. Here we describe the effect of cystatin C intracerebroventricular administration in rats prior to inducing a traumatic brain injury. We observed that cystatin C injection caused a dual response in post-traumatic brain injury recovery: higher doses (350 fmoles increased bleeding and mortality, whereas lower doses (3.5 to 35 fmoles decreased bleeding, neuronal damage and mortality. We also analyzed the expression of cathepsin B and cystatin C in the brains of control rats and of rats after a traumatic brain injury. Cathepsin B was detected in the brain stem, cerebellum, hippocampus and cerebral cortex of control rats. Cystatin C was localized to the choroid plexus, brain stem and cerebellum of control rats. Twenty-four hours after traumatic brain injury, we observed changes in both the expression and localization of both proteins in the cerebral cortex, hippocampus and brain stem. An early increase and intralysosomal expression of cystatin C after brain injury was associated with reduced neuronal damage.

  9. MW151 Inhibited IL-1β Levels after Traumatic Brain Injury with No Effect on Microglia Physiological Responses.

    Directory of Open Access Journals (Sweden)

    Adam D Bachstetter

    Full Text Available A prevailing neuroinflammation hypothesis is that increased production of proinflammatory cytokines contributes to progressive neuropathology, secondary to the primary damage caused by a traumatic brain injury (TBI. In support of the hypothesis, post-injury interventions that inhibit the proinflammatory cytokine surge can attenuate the progressive pathology. However, other post-injury neuroinflammatory responses are key to endogenous recovery responses. Therefore, it is critical that pharmacological attenuation of detrimental or dysregulated neuroinflammatory processes avoid pan-suppression of inflammation. MW151 is a CNS-penetrant, small molecule experimental therapeutic that restores injury- or disease-induced overproduction of proinflammatory cytokines towards homeostasis without immunosuppression. Post-injury administration of MW151 in a closed head injury model of mild TBI suppressed acute cytokine up-regulation and downstream cognitive impairment. Here, we report results from a diffuse brain injury model in mice using midline fluid percussion. Low dose (0.5-5.0 mg/kg administration of MW151 suppresses interleukin-1 beta (IL-1β levels in the cortex while sparing reactive microglia and astrocyte responses. To probe molecular mechanisms, we used live cell imaging of the BV-2 microglia cell line to demonstrate that MW151 does not affect proliferation, migration, or phagocytosis of the cells. Our results provide insight into the roles of glial responses to brain injury and indicate the feasibility of using appropriate dosing for selective therapeutic modulation of injurious IL-1β increases while sparing other glial responses to injury.

    Traumatic brain injury is the leading cause of mortality and disability in children in the developed countries. Despite the plasticity of an infant's brain, injury at this early stage can lead to important sequelae that will affect functioning later in life. The understanding of the functional profile after a traumatic brain injury is important for planning interventions and treatment resources once the preventive phase has failed. This was a retrospective study of the patients admitted in a neurorehabilitation unit with the aim of describing their functioning after an intensive rehabilitation programme. A total of 65 records of children with a mean age of 10.38 years that had been admitted to a rehabilitation programme were reviewed. Of the traumatic brain injuries, 89.2% were severe and 78.4% were secondary to traffic accidents. The mean length of stay was 79.35 days. At discharge, 72% were able to walk, but 76.9% showed some cognitive impairment. Despite good physical recovery, only 29.2% of the children were able to return to school. Permanence of deficits made 21.5% of the children unable to return to any type of education. The population under study was characterised by a good clinical outcome as well as good physical improvement. Nevertheless, cognitive problems were notable and were the main factor responsible for the changes in school attendance and return to normal life. Copyright © 2014 Sociedad Española de Neurocirugía.

    Full Text Available Restorative cell-based therapies for experimental brain injury, such as stroke and traumatic brain injury, substantially improve functional outcome. We discuss and review state of the art magnetic resonance imaging methodologies and their applications related to cell-based treatment after brain injury. We focus on the potential of magnetic resonance imaging technique and its associated challenges to obtain useful new information related to cell migration, distribution, and quantitation, as well as vascular and neuronal remodeling in response to cell-based therapy after brain injury. The noninvasive nature of imaging might more readily help with translation of cell-based therapy from the laboratory to the clinic.

    Full Text Available Objective: to evaluate the states of microcirculation, cerebral perfusion intracranial pressures in patients with isolated severe brain injury (SBI and to determine their possible relationships. Subjects and methods. 148 studies were performed in 16 victims with SBI. According to the outcome of brain traumatic disease, the patients were divided into two groups: 1 those who had a good outcome (n=8 and 2 those who had a fatal outcome (n=8. Microcirculation was examined by skin laser Doppler flowmetry using a LAKK-01 capillary blood flow laser analyzer (LAZMA Research-and-Production Association, Russian Federation. All the victims underwent surgical interventions to remove epi-, subdural, and intracerebral hematomas. A Codman subdural/intraparenchymatous intracranial pressure (ICD sensor (Johnson & Johnson, United Kingdom was intraoperatively inserted in the victims. Cerebral perfusion pressure (CPP was calculated using the generally accepted formula: CPP = MBP (mean blood pressure — ICD. ICD, CPP, and microcirculation were studied on postoperative days 1, 3, 5, and 7. Their values were recorded simultaneously. Ninety and 58 studies were conducted in the group of patients with good and fatal outcomes, respectively. Results. No correlation between the changes in MBP, ICD, and microcirculatory parameters suggested that the value of ICD was determined by the nature of brain damage and it was the leading and determining indicator in the diagnosis and treatment of secondary cerebral lesions. The amplitude of low-frequency fluctuations directly correlated with ICD, which indicated that they might be used to evaluate cerebral perfusion and impaired cerebral circulation indirectly in victims with severe brain injury. Conclusion. The laser Doppler flowmetric technique makes it possible not only to qualitatively, but also quantitatively determine changes in the tissue blood flow system in severe brain injury. With this technique, both the local and central

    Impairment in executive functioning can occur after mild stroke, mild Traumatic Brain Injury, and neurodegenerative disease, and this can have deleterious effects on employment outcomes, occupational functioning, and general quality of life. What is not as well identified is the symbiotic relationship between executive functioning and other important psychosocial constructs inherent in successful employees ("Employee Performance Enablers"), and how various aspects of the employment environment can enable or inhibit the success of the employee with executive functioning deficits in meeting their essential job functions ("Workplace Ecology"). From an extensive review of the literature and the author's practice experience, a clinical model was developed to elucidate these two critical variables, as well as to provide guidance for organizing, planning, and implementing interventions that will address both employee enablers and workplace ecology to affect positive return to work outcomes for individuals with mild brain injury.

    Full Text Available Obesity is an increasing public health problem affecting young people. The causes of obesity are multi-factorial among Chinese youth including lack of physical activity and poor eating habits. The use of an internet curriculum and cell phone reminders and texting may be an innovative means of increasing follow up and compliance with obese teens. The objectives of this study were to determine the feasibility of using an adapted internet curriculum and existing nutritional program along with cell phone follow up for obese Chinese teens.This was a randomized controlled study involving obese teens receiving care at a paediatric obesity clinic of a tertiary care hospital in Hong Kong. Forty-eight subjects aged 12 to 18 years were randomized into three groups. The control group received usual care visits with a physician in the obesity clinic every three months. The first intervention (IT group received usual care visits every three months plus a 12-week internet-based curriculum with cell phone calls/texts reminders. The second intervention group received usual care visits every three months plus four nutritional counselling sessions.The use of the internet-based curriculum was shown to be feasible as evidenced by the high recruitment rate, internet log-in rate, compliance with completing the curriculum and responses to phone reminders. No significant differences in weight were found between IT, sLMP and control groups.An internet-based curriculum with cell phone reminders as a supplement to usual care of obesity is feasible. Further study is required to determine whether an internet plus text intervention can be both an effective and a cost-effective adjunct to changing weight in obese youth.Chinese Clinical Trial Registry ChiCTR-TRC-12002624.

    Full Text Available Microarray analysis was used to investigate the changes of gene expression of ischemic stroke and acupuncture intervention in middle cerebral artery occlusion (MCAo rat brain. Results showed that acupuncture intervention had a remarkable improvement in neural deficit score, cerebral blood flow, and cerebral infarction volume of MCAo rats. Microarray analysis showed that a total of 627 different expression genes were regulated in ischemic stroke. 417 genes were upregulated and 210 genes were downregulated. A total of 361 different expression genes were regulated after acupuncture intervention. Three genes were upregulated and 358 genes were downregulated. The expression of novel genes after acupuncture intervention, including Tph1 and Olr883, was further analyzed by Real-Time Quantitative Polymerase Chain Reaction (RT-PCR. Upregulation of Tph1 and downregulation of Olr883 indicated that the therapeutic effect of acupuncture for ischemic stroke may be closely related to the suppression of poststroke depression and regulation of olfactory transduction. In conclusion, the present study may enrich our understanding of the multiple pathological process of ischemic brain injury and indicate possible mechanisms of acupuncture on ischemic stroke.

  20. Evaluation of Gene Therapy as an Intervention Strategy to Treat Brain Injury from Stroke

    Directory of Open Access Journals (Sweden)

    Amanda J Craig

    2016-05-01

    Full Text Available Stroke is a leading cause of death and disability, with a lack of treatments available to prevent cell death, regenerate damaged cells and pathways, or promote neurogenesis. The extended period of hours to weeks over which tissue damage continues to occur makes this disorder a candidate for gene therapy. This review highlights the development of gene therapy in the area of stroke, with the evolution of viral administration, in experimental stroke models, from pre-injury to clinically relevant timeframes of hours to days post-stroke. The putative therapeutic proteins being examined include anti-apoptotic, pro-survival, anti-inflammatory, and guidance proteins, targeting multiple pathways within the complex pathology, with promising results. The balance of findings from animal models suggests that gene therapy provides a viable translational platform for treatment of ischaemic brain injury arising from stroke.

    Purpose To determine the prevalence of and risk factors for needlesticks in interventional radiology physicians, as well as the attitudes, behaviors, and conditions that promote or interfere with reporting of these injuries. Materials and Methods A total of 3889 interventional radiologists from academic and private practice in the United States were surveyed by emailing all interventional radiologist members of the Society of Interventional Radiology, including attending-level physicians and trainees (April-August 2016). The institutional review board waived the need for consent. Questions inquired about the nature, frequency, and type of needlestick and sharps injuries and whether and to whom these incidents were reported. Stepwise regression was used to determine variables predicting whether injuries were reported. Results In total, 908 (23%) interventional radiologists completed at least a portion of the survey. Eight hundred fourteen (91%) of 895 respondents reported a prior needlestick injury, 583 (35%) of 895 reported at least one injury while treating an HIV-positive patient, and 626 (71%) of 884 reported prior training regarding needlestick injury. There was, on average, one needlestick for every 5 years of practice. Most needlestick or sharps injuries were self inflicted (711 [87%] of 817) and involved a hollow-bore device (464 [56%] of 824). Only 566 (66%) of 850 injuries were reported. The most common reasons for not reporting included perceived lack of utility of reporting (79 [28%] of 282), perceived low risk for injury (56 [20%] of 282), noncontaminated needle (53 [19%] of 282), too-lengthy reporting process (37 [13%] of 282), and associated stigma (23 [8%] of 282). Only 156 (25%) of 624 respondents informed their significant other. Stepwise regression assessing variables affecting the likelihood of reporting showed that male sex (P = .009), low-risk patient (P < .0001), self injury (P = .010), trainee status (P < .0001), and the total number of prior

    Objectives Rehabilitation clinical practice guidelines (CPGs) contain recommendation statements aimed at optimising care for adults with stroke and other brain injury. The aim of this study was to determine the quality, scope and consistency of CPG recommendations for rehabilitation covering the acquired brain injury populations. Design Systematic review. Interventions Included CPGs contained recommendations for inpatient rehabilitation or community rehabilitation for adults with an acquired brain injury diagnosis (stroke, traumatic or other non-progressive acquired brain impairments). Electronic databases (n=2), guideline organisations (n=4) and websites of professional societies (n=17) were searched up to November 2017. Two independent reviewers used the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument, and textual syntheses were used to appraise and compare recommendations. Results From 427 papers screened, 20 guidelines met the inclusion criteria. Only three guidelines were rated high (>75%) across all domains of AGREE-II; highest rated domains were ‘scope and purpose’ (85.1, SD 18.3) and ‘clarity’ (76.2%, SD 20.5). Recommendations for assessment and for motor therapies were most commonly reported, however, varied in the level of detail across guidelines. Conclusion Rehabilitation CPGs were consistent in scope, suggesting little difference in rehabilitation approaches between vascular and traumatic brain injury. There was, however, variability in included studies and methodological quality. PROSPERO registration number CRD42016026936. PMID:29490958

    A secondary data analysis of the National Commission on Children: 1990 Survey of Parents and Children was conducted with a subsample of 457 parent-teen pairs who responded to the "worry about AIDS" question. The teen's worry about contracting AIDS was associated with race, parent's education, the amount of discipline from the parent for engaging in sex, the teen's desire to talk to the parent about the problem of sex, the teen's rating of the neighborhood as a safe place to grow up, whether the parent listened to the teen's telephone interview, and the parent's response to whether his or her teen had a history of sexually transmitted disease. Of the parent-teen pairs in the subsample, 46% (N = 210) agreed in their responses about worry. Agreement was more frequent among the parent-teen pairs when compared to randomly constructed surrogate pairs. Dyadic analysis supported a family system view of perceived susceptibility.

    To explore brain pathology after mild traumatic brain injury by repeated magnetic resonance examination. A prospective follow-up study. Nineteen patients with mild traumatic brain injury presenting with Glasgow Coma Scale (GCS) 14-15. The patients were examined on day 2 or 3 and 3-7 months after the injury. The magnetic resonance protocol comprised conventional T1- and T2-weighted sequences including fluid attenuated inversion recovery (FLAIR), two susceptibility-weighted sequences to reveal haemorrhages, and diffusion-weighted sequences. Computer-aided volume comparison was performed. Clinical outcome was assessed by the Rivermead Post-Concussion Symptoms Questionnaire (RPQ), Hospital Anxiety and Depression Scale (HADS) and Glasgow Outcome Scale Extended (GOSE). At follow-up, 7 patients (37%) reported ≥  3 symptoms in RPQ, 5 reported some anxiety and 1 reported mild depression. Fifteen patients reported upper level of good recovery and 4 patients lower level of good recovery (GOSE 8 and 7, respectively). Magnetic resonance pathology was found in 1 patient at the first examination, but 4 patients (21%) showed volume loss at the second examination, at which 3 of them reported GOSE scores of 8. Loss of brain volume, demonstrated by computer-aided magnetic resonance imaging volumetry, may be a feasible marker of brain pathology after mild traumatic brain injury.

    Full Text Available Due to its special anatomical structures and immune pathophysiological mechanisms, brain damage repair is greatly different from damage repair of other systems. Secondary brain injury and inflammation are closely related. As a "double-edged sword", inflammation scavenges hazardous substances on the early stage of injury, but has side effects on normal brain tissue. The use of immunosuppressive therapy or hypothermia can inhibit immune injury, but the presence of reduced immunity may result in infection and tumorigenesis in the long term. Only reducing the autoimmune attack against brain tissue without affecting other immune capacity of the body will be optimized solution, and this paper will make a review on the research of immune tolerance in the treatment of brain injury with optimized program. doi: 10.3969/j.issn.1672-6731.2014.08.017

    2011-09-01

    Full Text Available Plasticity is the mechanism underlying brain’s potential capability to compensate injury. Recently several studies have shown that functional connections among brain areas are severely altered by brain injury and plasticity leading to a reorganization of the networks. This new approach studies the impact of brain injury by means of alteration of functional interactions. The concept of functional connectivity refers to the statistical interdependencies between physiological time series simultaneously recorded in various brain areas and it could be an essential tool for brain function studies, being its deviation from healthy reference an indicator for damage. In this article, we review studies investigating functional connectivity changes after brain injury and subsequent recovery, providing an accessible introduction to common mathematical methods to infer functional connectivity, exploring their capabilities, future perspectives and clinical uses in brain injury studies.

    This pilot study explored the experiences of brain injury survivors after a change in financial management (FM) independence. Using a qualitative descriptive design, 6 participants with acquired brain injury were recruited from a community brain injury organization and participated in semistructured interviews. Data were analyzed using thematic analysis. Three themes emerged from the interviews: (1) trajectory of FM change, involving family members as key change agents; (2) current FM situation, involving FM strategies such as automatic deposits and restricted budgets; and (3) the struggle for control, in which survivors desired control while also accepting supports for FM. This study identifies some of the challenges brain injury survivors face in managing their finances and the adjustment associated with a loss of FM independence. Occupational therapists should be aware of clients' experiences when supporting them through a change in independence. Copyright © 2016 by the American Occupational Therapy Association, Inc.

    Prescott, Sarah; Fleming, Jennifer; Doig, Emmah

    2017-06-11

    The aim of this study was to explore clinicians' experiences of implementing goal setting with community dwelling clients with acquired brain injury, to develop a goal setting practice framework. Grounded theory methodology was employed. Clinicians, representing six disciplines across seven services, were recruited and interviewed until theoretical saturation was achieved. A total of 22 clinicians were interviewed. A theoretical framework was developed to explain how clinicians support clients to actively engage in goal setting in routine practice. The framework incorporates three phases: a needs identification phase, a goal operationalisation phase, and an intervention phase. Contextual factors, including personal and environmental influences, also affect how clinicians and clients engage in this process. Clinicians use additional strategies to support clients with impaired self-awareness. These include structured communication and metacognitive strategies to operationalise goals. For clients with emotional distress, clinicians provide additional time and intervention directed at new identity development. The goal setting practice framework may guide clinician's understanding of how to engage in client-centred goal setting in brain injury rehabilitation. There is a predilection towards a client-centred goal setting approach in the community setting, however, contextual factors can inhibit implementation of this approach. Implications for Rehabilitation The theoretical framework describes processes used to develop achievable client-centred goals with people with brain injury. Building rapport is a core strategy to engage clients with brain injury in goal setting. Clients with self-awareness impairment benefit from additional metacognitive strategies to participate in goal setting. Clients with emotional distress may need additional time for new identity development.

    To characterize the MR findings of hypoxic-ischemic brain injury and to assess the value of the MR imaging. SE T1-, T2-weighted, and IR brain MR images of 44 infants and children with the past history of perinatal hypoxic insults were reviewed. Abnormal brain MR findings of 8 patients with birth history of prematurity and 36 patients with birth history of full-term/posterm including 7 with severe anoxic insult history, were compared in regard to the location and the character of the lesions. MRI demonstrated the followings; (1)abnormal signal intensity lesions of subcortical and/or deep cerebral white matter, cortex, and deep gray matter, (2)atrophy of the cerebral white matter, cortex and corpus callosum, with/without ventriculomegaly, and (3)delay in myelination. Periventricular and deep white matter lesions were demonstrated in the prematurity, the deep white matter lesions and/ or subcortical white matter lesions in the term/post-term, and deep gray matter lesions in the 7 patients with severe anoxic insults history. MR imaging was useful in the diagnosis of the hypoxic-ischemic brain injury, and the white and gray matter lesions were correlated with the time of the injury and the severity of hypoxic insult

    Full Text Available In the age of digital technology, as teens seem to be constantly connected online, via social media, and through mobile applications, it is no surprise that they increasingly turn to digital media to answer their health questions. This study is the first of its kind to survey a large, nationally-representative sample of teens to investigate how they use the newest digital technologies, including mobile apps, social networking sites, electronic gaming and wearable devices, to explore health topics. The survey covered the types of health topics teens most frequently search for, which technologies they are most likely to use and how they use them, and whether they report having changed their behaviors due to digital health information. In addition, this survey explores how the digital divide continues to impact adolescents. Results of this study indicate that teens are concerned about many health issues, ranging from fitness, sexual activity, drugs, hygiene as well as mental health and stress. As teens virtually always have a digital device at their fingertips, it is clear that public health interventions and informational campaigns must be tailored to reflect the ways that teens currently navigate digital health information and the health challenges that concern them most.

    Full Text Available Secondary injuries especially extremity fractures may be seen concurrently with traumatic brain injury (TBI. Peripheral nerve damages may accompany to these fractures and may be missed out, especially in acute stage. In this case report; damage of radial, ulnar and median nerves which was developed secondarily to distal humerus fracture that could not be detected in acute stage, in a patient who had motor vehicle accident (MVA. 29-year-old male patient was admitted with weakness in the right upper extremity. 9 months ago, he had traumatic brain injury because of MVA, and fracture of distal humerus was detected in follow-ups. Upon the suspect of the peripheral nerve injury, the diagnosis was confirmed with ENMG. The patient responded well to the rehabilitation program treatment. In a TBI patient, it must be kept in mind that there might be a secondary trauma and therefore peripheral nerve lesions may accompany to TBI.

    2014-01-01

    To determine if Goal Management Training (GMT) is effective for the rehabilitation of executive functions following brain injury when administered alone or in combination with other interventions. Systematic review, with quality appraisal specific to executive functions research and calculation of effect sizes. Twelve studies were included. Four studies were "Proof-of-principle" studies, testing the potential effectiveness of GMT and eight were rehabilitation studies. Effectiveness was greater when GMT was combined with other interventions. The most effective interventions appeared to be those combing GMT with: Problem Solving Therapy; personal goal setting; external cueing or prompting apply GMT to the current task; personal homework to increase patients' commitment and training intensity; ecological and daily life training activities rather than paper-and-pencil, office-type tasks. Level of support for GMT was higher for studies measuring outcome in terms of increases in participation in everyday activities rather than on measures of executive impairment. Comprehensive rehabilitation programs incorporating GMT, but integrating other approaches, are effective in executive function rehabilitation following brain injury in adults. There is insufficient evidence to support use of GMT as a stand-alone intervention.

    The purpose of this study was to investigate the neurological correlates of both subjective fatigue as well as objective fatigability in individuals with traumatic brain injury (TBI). The study has a cross-sectional design. Participants (N = 53) with TBI (77% male, mean age at injury 38 years, mean time since injury 1.8 years) underwent a structural magnetic resonance imaging (MRI) scan and completed the Fatigue Severity Scale (FSS), while a subsample (N = 36) was also tested with a vigilance task. While subjective fatigue (FSS) was not related to measures of brain lesions, multilevel analyses showed that a change in the participants' decision time was significantly predicted by grey matter (GM) lesions in the right frontal lobe. The time-dependent development of the participants' error rate was predicted by total brain white matter (WM) lesion volumes, as well as right temporal GM and WM lesion volumes. These findings could be explained by decreased functional connectivity of attentional networks, which results in accelerated exhaustion during cognitive task performance. The disparate nature of objectively measurable fatigability on the one hand and the subjective experience of fatigue on the other needs further investigation.

    This paper presents an overview of the key evaluation components for a set of community-wide teen pregnancy prevention initiatives. We first describe the performance measures selected to assess progress toward meeting short-term objectives on the reach and quality of implementation of evidence-based teen pregnancy prevention interventions and adolescent reproductive health services. Next, we describe an evaluation that will compare teen birth rates in intervention communities relative to synthetic control communities. Synthetic controls are developed via a data-driven technique that constructs control communities by combining information from a pool of communities that are similar to the intervention community. Finally, we share lessons learned thus far in the evaluation of the project, with a focus on those lessons that may be valuable for local communities evaluating efforts to reduce teen pregnancy.

    2017-11-01

    The aim of this study was to compare pathological findings after traumatic brain injury between autopsy and ante-mortem computed tomography (CT). A second aim was to identify changes in these findings between the primary posttraumatic CT and the last follow-up CT before death. Through the collaboration between clinical radiology and forensic medicine, 45 patients with traumatic brain injury were investigated. These patients had undergone ante-mortem CT as well as autopsy. During autopsy, the brain was cut in fronto-parallel slices directly after removal without additional fixation or subsequent histology. Typical findings of traumatic brain injury were compared between autopsy and radiology. Additionally, these findings were compared between the primary CT and the last follow-up CT before death. The comparison between autopsy and radiology revealed a high specificity (≥80%) in most of the findings. Sensitivity and positive predictive value were high (≥80%) in almost half of the findings. Sixteen patients had undergone craniotomy with subsequent follow-up CT. Thirteen conservatively treated patients had undergone a follow-up CT. Comparison between the primary CT and the last ante-mortem CT revealed marked changes in the presence and absence of findings, especially in patients with severe traumatic brain injury requiring decompression craniotomy. The main pathological findings of traumatic brain injury were comparable between clinical ante-mortem CT examinations and autopsy. Comparison between the primary CT after trauma and the last ante-mortem CT revealed marked changes in the findings, especially in patients with severe traumatic brain injury. Hence, clinically routine ante-mortem CT should be included in the process of autopsy interpretation. Copyright © 2017 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

    2000-01-01

    The aim of this work was to compare the results of the early brain scintigraphy in traumatic brain injury to the long term neuropsychological behavior. Twenty four patients had an ECD-Tc99m SPECT, within one month after the trauma; scintigraphic abnormalities were evaluated according to a semi-quantitative analysis. The neuropsychological clinical investigation was interpreted by a synthetic approach to evaluate abnormalities related to residual motor deficit, frontal behavior, memory and language disorders. Fourteen patients (58%) had sequela symptoms. SPECT revealed 80 abnormalities and CT scan only 31. Statistical analysis of uptake values showed significantly lower uptake in left basal ganglia and brain stem in patients with sequela memory disorders. We conclude that the brain perfusion scintigraphy is able to detect more lesions than CT and that it could really help to predict the neuropsychological behavior after severe head injury. Traumatology could become in the future a widely accepted indication of perfusion SPECT. (authors)

  9. Time dysperception perspective for acquired brain injury

    Directory of Open Access Journals (Sweden)

    Federica ePiras

    2014-01-01

    Full Text Available Distortions of time perception are presented by a number of neuropsychiatric disorders. Here we survey timing abilities in clinical populations with acquired brain injuries in key cerebral areas recently implicated in human studies of timing. We purposely analyzed the complex relationship between cognitive and contextual factors involved in time estimation, as to characterize the correlation between timed and other cognitive behaviors in each group. We assume that interval timing is a solid construct to study cognitive dysfunctions following brain injury, as timing performance is a sensitive metric of information processing, while temporal cognition has the potential of influencing a wide range of cognitive processes. Moreover, temporal performance is a sensitive assay of damage to the underlying neural substrate after a brain insult. Further research in neurological and psychiatric patients will definitively answer the question of whether time distortions are manifestations of cognitive and behavioral symptoms of brain damage and definitively clarify their mechanisms.

    Examine differences in maternal and paternal coping and distress following traumatic brain injury (TBI) and orthopedic injuries (OI). Concurrent cohort/prospective design with five assessments between 1 and an average of 7 years after injury of children aged 3-6 years hospitalized for TBI ( n  = 87) or OI ( n  = 119). Mixed models analyses were used to examine hypotheses. Overall, fathers reported greater depression and general distress than mothers 18 months after injury, but not at long-term follow-up. Active and acceptance coping were unrelated to parental sex, injury factors, or time since injury. A group × rater × time interaction was noted for Denial coping. Following severe TBI, fathers reported greater denial at 18 months, whereas mothers reported greater denial at the long-term follow-up. Denial coping did not differ between mothers and fathers following OI and moderate TBI. Parental response to early TBI is complex and may warrant clinical intervention even years after injury. © The Author 2016.

    2017-01-01

    We report a new application of optical coherence tomography (OCT) to investigate the cranial meninges in an animal model of brain injury in vivo.The injury is induced in a mouse due to skull thinning,in which the repeated and excessive drilling exerts mechanical stress on the mouse brain through the skull,resulting in acute and mild brain injury.Transcranial OCT imaging reveals an interesting virtual space between the cranial meningeal layers post skull thinning,which is gradually closed within hours.The finding suggests a promise of OCT as an effective tool to monitor the mechanical trauma in the small animal model of brain injury.

    2018-06-01

    Social anxiety (SA) following traumatic brain injury (TBI) has the potential to affect an individual's general psychological well-being and social functioning, however little research has explored factors associated with its development. The present study used hierarchical multiple regression to investigate the demographic, clinical and psychological factors associated with SA following TBI. A sample of 85 people who experienced TBI were recruited through social media websites and brain injury services across the North-West of England. The overall combined biopsychosocial model was significant, explaining 52-54.3% of the variance in SA (across five imputations of missing data). The addition of psychological variables (self-esteem, locus of control, self-efficacy) made a significant contribution to the overall model, accounting for an additional 12.2-13% of variance in SA above that explained by demographic and clinical variables. Perceived stigma was the only significant independent predictor of SA (B = .274, p = .005). The findings suggest that psychological variables are important in the development of SA following TBI and must be considered alongside clinical factors. Furthermore, the significant role of stigma highlights the need for intervention at both an individualised and societal level.

  14. Prevalence of traumatic brain injury in juvenile offenders: a meta-analysis.

    Farrer, Thomas J; Frost, R Brock; Hedges, Dawson W

    2013-01-01

    Studies of traumatic brain injury (TBI) among adult populations demonstrate that such injuries can lead to aggressive behaviors. Related findings suggest that incarcerated individuals have high rates of brain injuries. Such studies suggest that traumatic brain injury may be related to the etiology and recidivism of criminal behavior. Relatively few studies have examined the prevalence of TBI using a delinquent juvenile sample. In order to assess the relationship between TBI and juvenile offender status, the current study used meta-analytic techniques to examine the odds of having a TBI among juvenile offenders. Across 9 studies, we found that approximately 30% of juvenile offenders have sustained a previous brain injury. Across 5 studies that used a control group, a calculated summary odds ratio of 3.37 suggests that juvenile offenders are significantly more likely to have a TBI compared to controls. Results suggest that the rate of TBIs within the juvenile offender population is significant and that there may be a relationship between TBIs and juvenile criminal behavior.

    Full Text Available A review of the top-cited articles in a scientific discipline can identify areas of research that are well established and those in need of further development, and may, as a result, inform and direct future research efforts. Our objective was to identify and characterize the top-cited articles in traumatic brain injury (TBI. We used publically available software to identify the 50 TBI articles with the most lifetime citations, and the 50 TBI articles with the highest annual citation rates. A total of 73 articles were included in this review, with 27 of the 50 papers with the highest annual citation rates common to the cohort of 50 articles with the most lifetime citations. All papers were categorized by their primary topic or focus, namely: predictor of outcome, pathology/natural history, treatment, guidelines and consensus statements, epidemiology, assessment measures, or experimental model of TBI. The mean year of publication of the articles with the most lifetime citations and highest annual citation rates was, respectively, 1990 ± 14.9 years and 2003 ± 6.7 years. The 50 articles with the most lifetime citations typically studied predictors of outcome (34.0%, 17/50 and were specific to severe TBI (38.0%, 19/50. In contrast, the most common subject of papers with the highest annual citation rates was treatment of brain injury (22.0%, 11/50, and these papers most frequently investigated mild TBI (36.0%, 18/50. These findings suggest an intensified focus on mild TBI, which is perhaps a response to the dedicated attention these injuries are currently receiving in the context of sports and war, and because of their increasing incidence in developing nations. Our findings also indicate increased focus on treatment of TBI, possibly due to the limited efficacy of current interventions for TBI. This review provides a cross-sectional summary of some of the most influential articles in TBI, and a bibliometric examination of the current status of TBI

    To evaluate the effectiveness of an automated interactive prompting technology in supporting the morning routine of persons with acquired brain injury. The morning routine included maintaining personal hygiene and dressing. An inpatient neurorehabilitation hospital. Persons with acquired brain injury who required prompting when following their morning routine (n = 24), but were not limited by physical disability or dysphasia, took part in the study. Participants (67% with traumatic brain injury) had impairment on indices of memory and executive function. A randomized control trial evaluated the effect of an automated interactive micro-prompting device on the number of prompts by trained staff required for successful completion of the morning routine. Study-specific checklists assessed sequence performance, errors, and verbal prompts required over baseline, rehabilitation as usual, intervention, and return to baseline conditions. The intervention significantly reduced the support required to complete the task compared with usual rehabilitation. Micro-prompting technology is an effective assistive technology for cognition, which reduces support needs in people with significant cognitive impairments.

    Arts-based programmes have been shown to be useful for individuals with disturbances in cognitive and behavioural functioning. The current case studies examined the feasibility and effectiveness of a theatre skills training programme to facilitate social skills and participation for adolescents with childhood brain disorder. A case study approach was used with two adolescent participants. Focus groups were conducted immediately post-intervention, while a battery of quantitative measures were administered pre- and post-treatment, as well as 8 months post-treatment. Perceived and documented improvements in social skills and participation were observed from pre- to post-intervention and at follow-up. Results support the use of an arts-based intervention for youth with brain injuries to facilitate social skills and participation. Findings also highlight the need for more sensitive measures of these skills for youth with childhood brain disorder, who may have impaired awareness of their abilities and/or impairments in memory and language comprehension.

    In the present study Tsallis and Renyi entropy methods were used to study the electric activity of brain following hypoxic-ischemic (HI) injury. We investigated the performances of these parameterized information measures in describing the electroencephalogram (EEG) signal of controlled experimental animal HI injury. The results show that (a): compared with Shannon and Renyi entropy, the parameterized Tsallis entropy acts like a spatial filter and the information rate can either tune to long range rhythms or to short abrupt changes, such as bursts or spikes during the beginning of recovery, by the entropic index q; (b): Renyi entropy is a compact and predictive indicator for monitoring the physiological changes during the recovery of brain injury. There is a reduction in the Renyi entropy after brain injury followed by a gradual recovery upon resuscitation

    BACKGROUND: Aquaporin-4 (AQP-4) is closely related to the formation of brain edema. Neuronal apoptosis plays an important part in the conversion of swelled neuron following traumatic brain injury. At present, the studies on the protective effect of ketamine on brain have involved in its effect on aquaporin-4 expression and neuronal apoptosis in the brain tissues following brain injury in rats.OBJECTIVE: To observe the effect of ketamine on AQP-4 expression and neuronal apoptosis in the brain tissue following rat brain injury, and analyze the time-dependence of ketamine in the treatment of brain injury.DESIGN: Randomized grouping design, controlled animal trial.SETTING: Department of Anesthesiology, the Medical School Hospital of Qingdao University.MATERIALS: Totally 150 rats of clean grade, aged 3 months, were involved and randomized into control group and ketamine-treated group, with 75 rats in each. Each group was divided into 5 subgroups separately at 6,12, 24, 48 and 72 hours after injury, with 15 rats at each time point. Main instruments and reagents:homemade beat machine, ketamine hydrochloride (Hengrui Pharmaceutical Factory, Jiangsu), rabbit anti-rat AQP-4 polyclonal antibody, SABC immunohistochemical reagent kit and TUNEL reagent kit (Boster Co.,Ltd.,Wuhan).METHODS: This trial was carried out in the Institute of Cerebrovascular Disease, Medical College of Qingdao University during March 2005 to February 2006. A weight-dropping rat model of brain injury was created with Feeney method. The rats in the ketamine-treated group were intraperitoneally administered with 50 g/L ketamine (120 mg/kg) one hour after injury, but ketamine was replaced by normal saline in the control group. In each subgroup, the water content of cerebral hemisphere was measured in 5 rats chosen randomly. The left 10 rats in each subgroup were transcardiacally perfused with ketamine, then the brain tissue was made into paraffin sections and stained by haematoxylin and eosin. Neuronal

    To examine pre-licensure agreement on driving expectations and predictors of teen driving expectations among parent-teen dyads. Cross-sectional survey of 163 parent-teen dyads. Descriptive statistics, weighted Kappa coefficients, and linear regression were used to examine expectations about post-licensure teen driving. Teens reported high pre-licensure unsupervised driving (N = 79, 48.5%) and regular access to a car (N = 130, 81.8%). Parents and teens had low agreement on teen driving expectations (eg, after dark, κw = 0.23). Each time teens currently drove to/from school, their expectation of driving in risky conditions post-licensure increased (β = 0.21, p = .02). Pre-licensure improvement of parent-teen agreement on driving expectations are needed to have the greatest impact on preventing teens from driving in high risk conditions.

    Blast injury has become the major life- and function-threatening injuries in recent warfares. There is increased research interest in the mental disorders caused by blast-induced traumatic brain injury (bTBI), which has been proved as one of the "signature wounds" in modern battlefield. We reviewed the recent progresses in bTBI-related researches and concluded that the new era of blast injury research has shifted from the traditional physical impairments to cognitive dysfunctional/mental disorders that are proved to be more related to the outcome of combat casualty care.

    Forty cases diagnosed as diffuse brain injury (DBI) were studied by magnetic resonance imaging (MRI) performed within 3 days after injury. These cases were divided into two groups, which were the concussion group and diffuse axonal injury (DAI) group established by Gennarelli. There were no findings on computerized tomography (CT) in the concussion group except for two cases which had a brain edema or subarachnoid hemorrhage. But on MRI, high intensity areas on T2 weighted imaging were demonstrated in the cerebral white matter in this group. Many lesions in this group were thought to be edemas of the cerebral white matter, because of the fact that on serial MRI, they were isointense. In mild types of DAI, the lesions on MRI were located only in the cerebral white matter, whereas, in the severe types of DAI, lesions were located in the basal ganglia, the corpus callosum, the dorsal part of the brain stem as well as in the cerebral white matter. As for CT findings, parenchymal lesions were not visualized especially in mild DAI. Our results suggested that the lesions in cerebral concussion were edemas in cerebral white matter. In mild DAI they were non-hemorrhagic contusion; and in severe DAI they were hemorrhagic contusions in the cerebral white matter, the basal ganglia, the corpus callosum or the dorsal part of the brain stem.

    2018-04-01

    To synthesise the literature on the experiences of giving or receiving care for traumatic brain injury for people with traumatic brain injury, their family members and nurses in hospital and rehabilitation settings. Traumatic brain injury represents a major source of physical, social and economic burden. In the hospital setting, people with traumatic brain injury feel excluded from decision-making processes and perceive impatient care. Families describe inadequate information and support for psychological distress. Nurses find the care of people with traumatic brain injury challenging particularly when experiencing heavy workloads. To date, a contemporary synthesis of the literature on people with traumatic brain injury, family and nurse experiences of traumatic brain injury care has not been conducted. Integrative literature review. A systematic search strategy guided by the PRISMA statement was conducted in CINAHL, PubMed, Proquest, EMBASE and Google Scholar. Whittemore and Knafl's (Journal of Advanced Nursing, 52, 2005, 546) integrative review framework guided data reduction, data display, data comparison and conclusion verification. Across the three participant categories (people with traumatic brain injury/family members/nurses) and sixteen subcategories, six cross-cutting themes emerged: seeking personhood, navigating challenging behaviour, valuing skills and competence, struggling with changed family responsibilities, maintaining productive partnerships and reflecting on workplace culture. Traumatic brain injury creates changes in physical, cognitive and emotional function that challenge known ways of being in the world for people. This alters relationship dynamics within families and requires a specific skill set among nurses. Recommendations include the following: (i) formal inclusion of people with traumatic brain injury and families in care planning, (ii) routine risk screening for falls and challenging behaviour to ensure that controls are based on

    BackgroundDecreased heart rate variability (HRV) is a measure of autonomic dysfunction and brain injury in newborns with hypoxic ischemic encephalopathy (HIE). This study aimed to characterize the relationship between HRV and brain injury pattern using magnetic resonance imaging (MRI) in newborns with HIE undergoing therapeutic hypothermia.MethodsHRV metrics were quantified in the time domain (α S , α L , and root mean square at short (RMS S ) and long (RMS L ) timescales) and frequency domain (relative low-(LF) and high-frequency (HF) power) over 24-27 h of life. The brain injury pattern shown by MRI was classified as no injury, pure cortical/white matter injury, mixed watershed/mild basal ganglia injury, predominant basal ganglia or global injury, and death. HRV metrics were compared across brain injury pattern groups using a random-effects mixed model.ResultsData from 74 infants were analyzed. Brain injury pattern was significantly associated with the degree of HRV suppression. Specifically, negative associations were observed between the pattern of brain injury and RMS S (estimate -0.224, SE 0.082, P=0.006), RMS L (estimate -0.189, SE 0.082, P=0.021), and LF power (estimate -0.044, SE 0.016, P=0.006).ConclusionDegree of HRV depression is related to the pattern of brain injury. HRV monitoring may provide insights into the pattern of brain injury at the bedside.

    Safety training is strongly endorsed as one way to prevent teens from performing dangerous tasks at work. The objective of this mixed methods study was to characterize the safety training that teenagers receive on the job. From 2010 through 2012, focus groups and a cross-sectional survey were conducted with working teens. The top methods of safety training reported were safety videos (42 percent) and safety lectures (25 percent). The top lessons reported by teens were "how to do my job" and "ways to spot hazards." Males, who were more likely to do dangerous tasks, received less safety training than females. Although most teens are getting safety training, it is inadequate. Lessons addressing safety behaviors are missing, training methods used are minimal, and the time spent is insignificant. More research is needed to understand what training methods and lessons should be used, and the appropriate safety training length for effectively preventing injury in working teens. In addition, more research evaluating the impact of high-quality safety training compared to poor safety training is needed to determine the best training programs for teens. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Objective: To study the clinical characteristics, MRI findings, diagnosis, treatment and prognostic factors of patients with radiation induced brain stem injury in nasopharyngeal carcinoma. Methods: From January 1991 to January 2001, 24 patients with radiation injury of brain stem were treated, 14 males and 10 females. The latency ranged from 6 to 38 months, with a median of 18 months. The lesions were located in the pons in 10 patients, mesencephalon + pons in 4, pons + medulla oblongata in 5, medulla oblongata in 2 and mesencephalon + pons + medulla oblongata in 3. MRI findings showed that the injury was chiefly presented as hypointensity foci on T 1 WI and hyperintensity foci on T 2 WI. Results: Eighteen patients were treated with dexamethasone in the early phase, with symptoms relieved in 12 patients but unimproved in 6 patients. Eight 44% patients died within the 8-38 months, leaving 16 patients surviving for 0.5 to 6.0 years. Conclusions: Radiation injury of brain stem has a short latency with severe symptoms, signifying poor prognosis. It is suggested that adequate reduction of irradiation volume and dose at the brain stem should be able to lower the incidence of brain stem injury

    Recent evidence exists that enoxaparin can reduce brain injury because of its anticoagulant activity. To investigate the potential therapeutic effect of enoxaparin on cold-induced traumatic brain injury, at 20 minutes after modeling, male BALB/c mouse models of cold-induced traumatic brain injury were intraperitoneally administered 3 and 10 mg/kg enoxaparin or isotonic saline solution. Twenty-four hours later, enoxaparin at 10 mg/kg greatly reduced infarct volume, decreased cell apoptosis in the cortex and obviously increased serum level of total antioxidant status. By contrast, administration of enoxaparin at 3 mg/kg did not lead to these changes. These findings suggest that enoxaparin exhibits neuroprotective effect on cold-induced traumatic brain injury in a dose-dependent manner.

  13. Neuropsychiatric Disturbances and Hypopituitarism After Traumatic Brain Injury in an Elderly Man

    Full Text Available Neuropsychiatric or cognitive disturbances are common complications after traumatic brain injury. They are commonly regarded as irreversible sequelae of organic brain injuries. We report a case of hypopituitarism in a 77-year-old man who presented with long-term neuropsychiatric disturbances, including cognitive impairment, disturbed sleep patterns, personality change, loss of affect, and visual and auditory hallucinations after a traumatic subdural hemorrhage. The treatment response to hormone replacement therapy was nearly complete. Hypopituitarism is rarely considered in patients who sustain traumatic brain injury and the neuropsychiatric manifestations of posttraumatic hypopituitarism have rarely been reported. This case highlights the importance of hypopituitarism as a potential reversible cause of neuropsychiatric disturbances after traumatic brain injury.

    We aimed to determine the association between scalp hematoma characteristics and traumatic brain injuries in young children with blunt head trauma who have no other symptoms or signs suggestive of traumatic brain injuries (defined as "isolated scalp hematomas"). This was a secondary analysis of children younger than 24 months with minor blunt head trauma from a prospective cohort study in 25 Pediatric Emergency Care Applied Research Network emergency departments. Treating clinicians completed a structured data form. For children with isolated scalp hematomas, we determined the prevalence of and association between scalp hematoma characteristics and (1) clinically important traumatic brain injury (death, neurosurgery for traumatic brain injury, intubation >24 hours for traumatic brain injury, or positive computed tomography (CT) scan in association with hospitalization ≥2 nights for traumatic brain injury); and (2) traumatic brain injury on CT. Of 10,659 patients younger than 24 months were enrolled, 2,998 of 10,463 (28.7%) with complete data had isolated scalp hematomas. Clinically important traumatic brain injuries occurred in 12 patients (0.4%; 95% confidence interval [CI] 0.2% to 0.7%); none underwent neurosurgery (95% CI 0% to 0.1%). Of 570 patients (19.0%) for whom CTs were obtained, 50 (8.8%; 95% CI 6.6% to 11.4%) had traumatic brain injuries on CT. Younger age, non-frontal scalp hematoma location, increased scalp hematoma size, and severe injury mechanism were independently associated with traumatic brain injury on CT. In patients younger than 24 months with isolated scalp hematomas, a minority received CTs. Despite the occasional presence of traumatic brain injuries on CT, the prevalence of clinically important traumatic brain injuries was very low, with no patient requiring neurosurgery. Clinicians should use patient age, scalp hematoma location and size, and injury mechanism to help determine which otherwise asymptomatic children should undergo

    To determine whether caregivers' medical and psychiatric histories, coping style, and social support predict global distress and perceived burden. Correlational, cohort study. A total of 114 caregivers of persons with moderate to severe traumatic brain injury, assessed 1 year postinjury. Ratings of caregivers' medical and psychiatric history; Disability Rating Scale; Ways of Coping Questionnaire; Multidimensional Scale of Perceived Social Support; Brief Symptom Inventory; and Modified Caregiver Appraisal Scale. Caregivers' medical and psychiatric histories predicted global distress, after accounting for education, sex, income, and relationship, as well as disability of the person with injury. Increased use of escape-avoidance as a coping strategy was related to increased distress. Perceived burden was predicted by disability in the person with injury, use of escape-avoidance, and perceived social support. Caregivers' preinjury functioning is more predictive of global distress, whereas the functioning of the person with injury is more predictive of injury-related burden. Caregivers' medical and psychiatric histories are important considerations when targeting interventions; global stress management strategies may be as important as assisting with injury-related issues.

    In our study, FLAIR images and multishot echo planar imaging T2-weighted images (EPI T2-WI) were used in addition to conventional T1-weighted images, T2-weighted images and T2-weighted sagittal images. In this series we focused our attention on small parenchymatous lesions of a mild or moderate form of diffuse brain injury. These injuries are shown as high intensity areas on T2-weighted images (T2-high intensity lesions) but are not visualized in CT images. This series consisted of 29 patients who were diagnosed with diffuse brain injury and whose CT scans showed a Diffuse Injury I or II. Nineteen patients were studied in an acute or subacute stage. In all but 3 patients, small T2-high intensity lesions were found in the brain parenchyma. In the follow-up study brain edema was suggested because the lesions tended to be absent within 3 months in T2-weighted images and FLAIR. In 10 patients examined during a chronic stage. Small hemorrhages in patients with Diffuse Injury II were shown with variable intensities on the conventional T1- and T2-weighted images, but were visualized with low intensity in an EPI T2-WI. In diffuse brain injuries, small T2-high intensity lesions have been considered to be brain edema or ischemic insults. Our data however, suggested that microhemorrhages associated with brain edema were resent in most of the supratentorial lesions, and in more than a half of the lesions in the corpus callosum and the brain stem. These findings appear similar to contusions, which are defined as traumatic bruises of the neural parenchyma. The use of MRI has increased our understanding of in vivo pathological changes in mild or moderate forms of diffuse brain injury. (K.H.)

    Children who are born preterm are at risk for encephalopathy of prematurity, a leading cause of cerebral palsy, cognitive delay and behavioral disorders. Current interventions are limited and none have been shown to reverse cognitive and behavioral impairments, a primary determinant of poor quality of life for these children. Moreover, the mechanisms of perinatal brain injury that result in functional deficits and imaging abnormalities in the mature brain are poorly defined, limiting the potential to target interventions to those who may benefit most. To determine whether impairments are reversible after a prenatal insult, we investigated a spectrum of functional deficits and diffusion tensor imaging (DTI) abnormalities in young adult animals. We hypothesized that prenatal transient systemic hypoxia-ischemia (TSHI) would induce multiple functional deficits concomitant with reduced microstructural white and gray matter integrity, and tested whether these abnormalities could be ameliorated using postnatal erythropoietin (EPO), an emerging neurorestorative intervention. On embryonic day 18 uterine arteries were transiently occluded for 60min via laparotomy. Shams underwent anesthesia and laparotomy for 60min. Pups were born and TSHI pups were randomized to receive EPO or vehicle via intraperitoneal injection on postnatal days 1 to 5. Gait, social interaction, olfaction and open field testing was performed from postnatal day 25-35 before brains underwent ex vivo DTI to measure fractional anisotropy, axial diffusivity and radial diffusivity. Prenatal TSHI injury causes hyperactivity, impaired gait and poor social interaction in young adult rats that mimic the spectrum of deficits observed in children born preterm. Collectively, these data show for the first time in a model of encephalopathy of prematurity that postnatal EPO treatment mitigates impairments in social interaction, in addition to gait deficits. EPO also normalizes TSHI-induced microstructural abnormalities

    Full Text Available Traumatic brain injury is one of the major causes for invalidization in children. The research purpose is an integrated study of consequences of severe and moderate closed traumatic brain injury in children and evaluation of their dynamics during therapy by means of a no tropic medication — cerebrolysin (Ebewe Pharma, Austria. The total of 283 children aged from 4 to 14 years were examined in the longaterm period of severe and moderate closed traumatic brain injury, from 6 months to 4 years after injury. Their neurological status was characterized by nona specific focal symptoms along with evident motor coordination disturbances, elements of dynamic and staticoloa comotory ataxia, reduction in execution speed of serial movements. Statistically significant differences with ageamatched controls were confirmed for measures of acousticaverbal memory and sustained attention. Posttraumatic epilepsy developed in 16 (5,7% patients with the onset of secondarily generalized seizures in 4–12 months following the injury. Effectiveness of the no tropic medication was evaluated in 60 patients aged from 7 to 12 years, who were distributed into 2 equal groups. The research has confirmed a positive effect of no tropic medication in the treatment of traumatic brain injury consequences manifested in the regression of headaches, fatigue, motor coordination disturbances along with improvements of memory, attention, intellectual performance rates, as well as EEG characteristics.Key words: traumatic brain injury, consequences, children, therapy, nootropic medications.

    To explore the relationship between location and pattern of brain injury identified on MRI and prolonged low response state in children post-traumatic brain injury (TBI). This observational study compared 15 children who spontaneously recovered within 30 days post-TBI to 17 who remained in a prolonged low response state. 92.9% of children with brain stem injury were in the low response group. The predicted probability was 0.81 for brain stem injury alone, increasing to 0.95 with a regional pattern of injury to the brain stem, basal ganglia, and thalamus. Low response state in children post-TBI is strongly correlated with two distinctive regions of injury: the brain stem alone, and an injury pattern to the brain stem, basal ganglia, and thalamus. This study demonstrates the need for large-scale clinical studies using MRI as a tool for outcome assessment in children and adolescents following severe TBI.

    Initiatives designed to prevent teen pregnancy are often based on adult perceptions of the negative aspects of a teen birth. Qualitative research has revealed that teens may perceive positive rewards associated with teen parenting. These perceptions have not yet been examined through survey research. The theory of reasoned action proposes that individuals assess the costs and rewards prior to engaging in a behavior and provides a framework for the development of a survey instrument designed to measure adolescent thoughts about the costs and rewards of the teen parenting experience. This manuscript describes the development and testing of a quantitative survey instrument designed to measure adolescents' perceptions. Pretesting, piloting, exploratory factor analysis, and a variety of reliability and validity measures were used to determine the value of the measure. The thoughts on teen parenting survey (TTPS) demonstrates an alpha level of .90. The TTPS yields a cumulative score of teen perceptions about the impact of a teen birth during the adolescent years that may be used to assess youth beliefs, correlated with demographic data, used to identify teens at risk for pregnancy/parenting, or provide a pretest/posttest to assess the effectiveness of interventions designed to foster realistic attitudes toward teen parenting.

    Traumatic brain injury is a leading cause of cognitive and behavioral deficits in children in the US each year. None of the current diagnostic tools, such as quantitative cognitive and balance tests, have been validated to identify mild traumatic brain injury in infants, adults and animals. In this preliminary study, we report a novel, quantitative tool that has the potential to quickly and reliably diagnose traumatic brain injury and which can track the state of the brain during recovery across multiple ages and species. Using 32 scalp electrodes, we recorded involuntary auditory event-related potentials from 22 awake four-week-old piglets one day before and one, four, and seven days after two different injury types (diffuse and focal) or sham. From these recordings, we generated event-related potential functional networks and assessed whether the patterns of the observed changes in these networks could distinguish brain-injured piglets from non-injured. Piglet brains exhibited significant changes after injury, as evaluated by five network metrics. The injury prediction algorithm developed from our analysis of the changes in the event-related potentials functional networks ultimately produced a tool with 82% predictive accuracy. This novel approach is the first application of auditory event-related potential functional networks to the prediction of traumatic brain injury. The resulting tool is a robust, objective and predictive method that offers promise for detecting mild traumatic brain injury, in particular because collecting event-related potentials data is noninvasive and inexpensive.

    Prospectively track teen childbirths in maltreated and nonmaltreated females and test the hypothesis that child maltreatment is an independent predictor of subsequent teen childbirth over and above demographic characteristics and other risk factors. Nulliparous adolescent females (N = 435) aged 14 to 17 years were assessed annually through age 19 years. Maltreated females were referred by Child Protective Services agencies for having experienced substantiated sexual abuse, physical abuse, or neglect within the preceding 12 months. Comparison females were matched on race, family income, age and family constellation. Teen childbirth was assessed via self-report during annual interviews. Births were confirmed using hospital delivery records. Seventy participants gave birth during the study, 54 in the maltreated group and 16 in the comparison group. Maltreated females were twice as likely to experience teen childbirth after controlling for demographic confounds and known risk factors (odds ratio = 2.17, P = 0.01). Birth rates were highest for sexually abused and neglected females. Sexual abuse and neglect were both independent predictors of teen childbirth after controlling for demographic confounds, other risk factors and alternative forms of maltreatment occurring earlier in development. Results provide evidence that sexual abuse and neglect are unique predictors of subsequent teen childbirth. Partnerships between protective service providers and teen childbirth prevention strategists hold the best promise for further reducing the US teen birth rate. Additional research illuminating the pathways to teen childbirth for differing forms of maltreatment is needed so that tailored interventions can be realized.

    Traumatic brain injury is a leading cause of death and disability. Optimizing the recovery from coma is a priority in seeking to improve patients' functional outcomes. Standards of care have not been established: pharmacological interventions, right median nerve and sensory stimulation, dorsal column stimulation (DCS), deep brain stimulation, transcranial magnetic stimulation, hyperbaric oxygen therapy and cell transplantation have all been utilized with contrasting results. The aim of this review is to clarify the indications for the various techniques and to guide the clinical practice towards an earlier coma arousal. A systematic bibliographic search was undertaken using the principal search engines (Pubmed, Embase, Ovid and Cochrane databases) to locate the most pertinent studies. Traumatic injury is a highly individualized process, and subsequent impairments are dependent on multiple factors: this heterogeneity influences and determines therapeutic responses to the various interventions.

    The most common head injury in sports is concussion and experiencing multiple concussions in a short period of time sometimes can cause severe brain damage. In this paper, we investigate severe brain damage due to repeated head injury in sports and discuss the pathophysiology of repeated sports injury. The majority of these severe cases are usually male adolescents or young adults that suffer a second head injury before they have recovered from the first head injury. All cases that could be confirmed by brain CT scan after the second injury revealed brain swelling associated with a thin subdural hematoma. We suggested that the existence of subdural hematoma is one of the major causes of brain swelling after repeated head injury in sports. Since repeated concussions occurring within a short period may have a risk for severe brain damage, the diagnosis for initial cerebral concussion should be done appropriately. To prevent catastrophic brain damage, the player who suffered from concussion should not engage in any sports before recovery. The american Academy of Neurology and Colorado Medical Society set a guideline to return to play after cerebral concussion. An international conference on concussion in sports was held at Prague in 2004. The summary and agreement of this meeting was published and the Sports Concussion Assessment Tool (SCAT) was introduced to treat sports-related concussion. In addition, a number of computerized cognitive assessment tests and test batteries have been developed to allow athletes to return to play. It is important that coaches, as well as players and trainers, understand the medical issues involved in concussion. (author)

    The brain is the major dose-limiting organ in patients undergoing radiotherapy for assorted conditions. Radiation-induced brain injury is common and mainly occurs in patients receiving radiotherapy for malignant head and neck tumors, arteriovenous malformations, or lung cancer-derived brain metastases. Nevertheless, the underlying mechanisms of radiation-induced brain injury are largely unknown. Although many treatment strategies are employed for affected individuals, the effects remain suboptimal. Accordingly, animal models are extremely important for elucidating pathogenic radiation-associated mechanisms and for developing more efficacious therapies. So far, models employing various animal species with different radiation dosages and fractions have been introduced to investigate the prevention, mechanisms, early detection, and management of radiation-induced brain injury. However, these models all have limitations, and none are widely accepted. This review summarizes the animal models currently set forth for studies of radiation-induced brain injury, especially rat and mouse, as well as radiation dosages, dose fractionation, and secondary pathophysiological responses.

  10. Issues of cultural diversity in acquired brain injury (ABI) rehabilitation.

    2014-01-01

    With the general population in the United States becoming increasingly diverse, it is important for rehabilitation professionals to develop the capacity to provide culturally sensitive treatment. This is especially relevant when working with minority populations who have a higher risk for brain injury and poorer rehabilitation outcomes. This article presents a number of clinical vignettes to illustrate how cultural factors can influence behavior in patients recovering from brain injury, as well as rehabilitation staff. The main objectives are to raise awareness among clinicians and stimulate research ideas by highlighting some real world examples of situations where a specialized, patient-centered approach needs to consider factors of cultural diversity. Because one's own world view impacts the way we see the world and interpret behavior, it is important to understand one's own ethnocentrism when dealing with a diverse population of patients with brain injury where behavioral sequelae are often expected. Being able to see behavior after brain injury with an open mind and taking into account cultural and contextual factors is an important step in developing culturally competent rehabilitation practices.

    The Affordable Care Act provides funding for home-visiting programs to reduce health care disparities, despite limited evidence that existing programs can overcome implementation and evaluation challenges with at-risk populations. The authors report 36-month outcomes of the paraprofessional-delivered Family Spirit home-visiting intervention for American Indian teen mothers and children. Expectant American Indian teens (N=322, mean age=18.1 years) from four southwestern reservation communities were randomly assigned to the Family Spirit intervention plus optimized standard care or optimized standard care alone. Maternal and child outcomes were evaluated at 28 and 36 weeks gestation and 2, 6, 12, 18, 24, 30, and 36 months postpartum. At baseline the mothers had high rates of substance use (>84%), depressive symptoms (>32%), dropping out of school (>57%), and residential instability (51%). Study retention was ≥83%. From pregnancy to 36 months postpartum, mothers in the intervention group had significantly greater parenting knowledge (effect size=0.42) and parental locus of control (effect size=0.17), fewer depressive symptoms (effect size=0.16) and externalizing problems (effect size=0.14), and lower past month use of marijuana (odds ratio=0.65) and illegal drugs (odds ratio=0.67). Children in the intervention group had fewer externalizing (effect size=0.23), internalizing (effect size=0.23), and dysregulation (effect size=0.27) problems. The paraprofessional home-visiting intervention promoted effective parenting, reduced maternal risks, and improved child developmental outcomes in the U.S. population subgroup with the fewest resources and highest behavioral health disparities. The methods and results can inform federal efforts to disseminate and sustain evidence-based home-visiting interventions in at-risk populations.

    Individuals with Acquired Brain Injury (ABI) could benefit from further cognitive rehabilitation, after they have returned home. However, a lack of specialist services to provide such rehabilitation often prevents this. This leads to reduced reintegration of patients, increased social disadvantages and ultimately, higher economic costs. 10 months post-stroke, a 69 year-old woman was discharged from an inpatient rehabilitation program and returned home with severe cognitive impairments. We describe a pilot project which provided an individualised, low cost rehabilitation program, supervised and trained by a neuropsychologist. Progress was monitored every 3 months in order to decide on continuation of the program, based on the achieved results and predicted costs. Post intervention, despite severe initial impairment, cognitive and most notably daily functioning had improved. Although the financial investment was moderately high for the family, the intervention was still considered cost-effective when compared with the required costs of care in a local non-specialist care home. Moreover, the pilot experience was used to build a "local expert team" available for other individuals requiring rehabilitation. These results encourage the development of similar local "low cost" teams in the community, to provide scientifically-grounded cognitive rehabilitation for ABI patients returning home.

    Cognitive rehabilitation is established as a core intervention within rehabilitation programs following a traumatic brain injury (TBI). Digitally enabled assistive technologies offer opportunities for clinicians to increase remote access to rehabilitation supporting transition into home. Brain Computer Interface (BCI) systems can harness the residual abilities of individuals with limited function to gain control over computers through their brain waves. This paper presents an online cognitive rehabilitation application developed with therapists, to work remotely with people who have TBI, who will use BCI at home to engage in the therapy. A qualitative research study was completed with people who are community dwellers post brain injury (end users), and a cohort of therapists involved in cognitive rehabilitation. A user-centered approach over three phases in the development, design and feasibility testing of this cognitive rehabilitation application included two tasks (Find-a-Category and a Memory Card task). The therapist could remotely prescribe activity with different levels of difficulty. The service user had a home interface which would present the therapy activities. This novel work was achieved by an international consortium of academics, business partners and service users.

    Introduction Day-of-injury (DOI) brain lesion volumes in traumatic brain injury (TBI) patients are rarely used to predict long-term outcomes in the acute setting. The purpose of this study was to investigate the relationship between acute brain injury lesion volume and rehabilitation outcomes in patients with TBI at a Level One Trauma Center. Methods Patients with TBI who were admitted to our rehabilitation unit after the acute care trauma service from February 2009-July 2011 were eligible for the study. Demographic data and outcome variables including cognitive and motor FIM scores, length of stay (LOS) in the rehabilitation unit, and ability to return to home were obtained. DOI quantitative injury lesion volumes and degree of midline shift were obtained from day-of-injury (DOI) brain computed tomography (CT) scans. A multiple step-wise regression model including 13 independent variables was created. This model was used to predict post-rehabilitation outcomes, including FIM scores and ability to return to home. PInjury Severity Score 24.7±9.9, and head Abbreviated Injury Scale score 3.73±0.97. Acute hospital length of stay (LOS) was 12.3±8.9 days and rehabilitation LOS was 15.9±9.3 days. Day-of-injury TBI lesion volumes were inversely associated with cognitive FIM scores at rehabilitation admission (p=0.004) and discharge (p=0.004) and inversely associated with ability to be discharged to home after rehabilitation (p=0.006). Conclusion In a cohort of patients with moderate to severe TBI requiring a rehabilitation unit stay after the acute care hospital stay, DOI brain injury lesion volumes are associated with worse cognitive FIM scores at the time of rehabilitation admission and discharge. Smaller injury volumes were associated with eventual discharge to home. Volumetric neuroimaging in the acute injury phase may improve surgeons’ ultimate outcome predictions in TBI patients.

    Penetrating traumatic brain injury (PTBI) is a significant cause of death and disability in the United States. Inflammasomes are one of the key regulators of the interleukin (IL)-1β mediated inflammatory responses after traumatic brain injury. However, the contribution of inflammasome signaling after PTBI has not been determined. In this study, adult male Sprague-Dawley rats were subjected to sham procedures or penetrating ballistic-like brain injury (PBBI) and sacrificed at various time-points. Tissues were assessed by immunoblot analysis for expression of IL-1β, IL-18, and components of the inflammasome: apoptosis-associated speck-like protein containing a caspase-activation and recruitment domain (ASC), caspase-1, X-linked inhibitor of apoptosis protein (XIAP), nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3), and gasdermin-D (GSDMD). Specific cell types expressing inflammasome proteins also were evaluated immunohistochemically and assessed quantitatively. After PBBI, expression of IL-1β, IL-18, caspase-1, ASC, XIAP, and NLRP3 peaked around 48 h. Brain protein lysates from PTBI animals showed pyroptosome formation evidenced by ASC laddering, and also contained increased expression of GSDMD at 48 h after injury. ASC-positive immunoreactive neurons within the perilesional cortex were observed at 24 h. At 48 h, ASC expression was concentrated in morphologically activated cortical microglia. This expression of ASC in activated microglia persisted until 12 weeks following PBBI. This is the first report of inflammasome activation after PBBI. Our results demonstrate cell-specific patterns of inflammasome activation and pyroptosis predominantly in microglia, suggesting a sustained pro-inflammatory state following PBBI, thus offering a therapeutic target for this type of brain injury.

    Low level of thyroid hormone is a strong independent risk factor for white matter (WM) injury, a major cause of cerebral palsy, in preterm infants. Thyroxin upregulates brain-derived neurotrophic factor during development. We hypothesized that thyroxin protected against preoligodendrocyte apoptosis and WM injury in the immature brain via upregulation of brain-derived neurotrophic factor. Postpartum (P) day-7 male rat pups were exposed to hypoxic ischemia (HI) and intraperitoneally injected with thyroxin (T4; 0.2 mg/kg or 1 mg/kg) or normal saline immediately after HI at P9 and P11. WM damage was analyzed for myelin formation, axonal injury, astrogliosis, and preoligodendrocyte apoptosis. Neurotrophic factor expression was assessed by real-time polymerase chain reaction and immunohistochemistry. Neuromotor functions were measured using open-field locomotion (P11 and P21), inclined plane climbing (P11), and beam walking (P21). Intracerebroventricular injection of TrkB-Fc or systemic administration of 7,8-dihydroxyflavone was performed. On P11, the HI group had significantly lower blood T4 levels than the controls. The HI group showed ventriculomegaly and marked reduction of myelin basic protein immunoreactivities in the WM. T4 (1 mg/kg) treatment after HI markedly attenuated axonal injury, astrocytosis, and microgliosis, and increased preoligodendrocyte survival. In addition, T4 treatment significantly increased myelination and selectively upregulated brain-derived neurotrophic factor expression in the WM, and improved neuromotor deficits after HI. The protective effect of T4 on WM myelination and neuromotor performance after HI was significantly attenuated by TrkB-Fc. Systemic 7,8-dihydroxyflavone treatment ameliorated hypomyelination after HI injury. T4 protects against WM injury at both pathological and functional levels via upregulation of brain-derived neurotrophic factor-TrkB signaling in the immature brain.

    Full Text Available Penetrating cranial injury by mechanisms other than are exceedingly rare, and so strategies and guidelines for the management of PBI are largely informed by data from higher-velocity penetrating injuries. Here we present a case of penetrating brain injury by the low velocity mechanism of a harpoon from an underwater fishing speargun in an attempted suicide by a 56-year-old Caucasian male. The case raised a number of interesting points in management of lower-velocity penetrating brain injury (LVPBI, including benefit in delaying foreign body removal to allow for tamponade; the importance of history taking in establishing the social/legal significance of the events surrounding the injury; the use of cerebral angiogram in all cases of PBI; advantages of using DECT to reduce artifact when available; and antibiotic prophylaxis in the context of idiosyncratic histories of usage of penetrating objects before coming in contact with the intracranial environment. We present here the management of the case in full along with an extended discussion and review of existing literature regarding key points in management of LVPBI vs. higher velocity forms of intracranial injury.

    Previous studies have shown that the cerebral complications associated with skin burn victims are correlated with brain damage. The aim of this study was to determine whether systemic thermal injury induces inflammatory responses in the brain. Sprague Dawley rats (n=28) were studied in thermal injury and control groups. Animals from the thermal injury (n=14) and control (n=14) group were anesthetized and submerged to the neck vertically in 85 degrees C water for 6 s producing a third degree burn affecting 60-70% of the animal body surface area. The controls were submerged in 37 degrees C water for 6 s. Early expression of tumor necrosis factor-alpha (TNF-alpha), interleukin 1-beta (IL-1beta), and intracellular cell adhesion molecules (ICAM-1) protein levels in serum were determined at 3 (n=7) and 7 h (n=7) by enzyme-linked immunoabsorbent assay (ELISA). mRNA of TNF-alpha, IL-1beta, and ICAM-1 in the brain was measured at the same time points with a real-time reverse transcriptase-polymerase chain reaction (RT-PCR). An equal animal number was used for controls. Systemic inflammatory responses were demonstrated by dramatic up-regulations (5-50 fold) of TNF-alpha, IL-1beta, and ICAM-1 protein level in serum at 7 h after the thermal injury. However, as early as 3 h after peripheral thermal injury, a significant increase (3-15 fold) in mRNA expression of TNF-alpha, IL-1beta and ICAM-1 was observed in brain homogenates, with increased levels remaining at 7 h after injury. This study demonstrated an early inflammatory response in the brain after severe peripheral thermal injury. The cerebral inflammatory reaction was associated with expression of systemic cytokines and an adhesion molecule.

    To characterize and compare subgroups of survivors with assault-related versus self-inflicted traumatic brain injuries (TBIs) via firearms at the time of inpatient rehabilitation and at 1-, 2-, and 5-year follow-up. Secondary analysis of data from the Traumatic Brain Injury Model Systems National Database (TBIMS NDB), a multicenter, longitudinal cohort study. Retrospective analyses of a subset of individuals enrolled in the TBIMS NDB. Individuals 16 years and older (N=399; 310 via assault, 89 via self-inflicted injury) with a primary diagnosis of TBI caused by firearm injury enrolled in the TBIMS NDB. Not applicable. Disability Rating Scale, Glasgow Outcome Scale-Extended, sociodemographic variables (sex, age, race, marital status), injury-related/acute care information (posttraumatic amnesia, loss of consciousness, time from injury to acute hospital discharge), and mental health variables (substance use history, psychiatric hospitalizations, suicide history, incarcerations). Individuals who survived TBI secondary to a firearm injury differed by injury mechanism (assault vs self-inflicted) on critical demographic, injury-related/acute care, and mental health variables at inpatient rehabilitation and across long-term recovery. Groups differed in terms of geographic area, age, ethnicity, education, marital status, admission Glasgow Coma Scale score, and alcohol abuse, suicide attempts, and psychiatric hospitalizations at various time points. These findings have implications for prevention (eg, mental health programming and access to firearms in targeted areas) and for rehabilitation planning (eg, by incorporating training with coping strategies and implementation of addictions-related services) for firearm-related TBI, based on subtype of injury.

    Full Text Available Objective: to study the development of acute respiratory distress syndrome (ARDS in victims with isolated severe brain injury (SBI. Subject and methods. 171 studies were performed in 16 victims with SBI. Their general condition was rated as very critical. The patients were divided into three groups: 1 non-ARDS; 2 Stage 1 ARDS; and 3 Stage 2 ARDS. The indicators of Stages 1 and 2 were assessed in accordance with the classification proposed by V. V. Moroz and A. M. Golubev. Intracranial pressure (ICP, extravascular lung water index, pulmonary vascular permeability, central hemodynamics, oxygenation index, lung anastomosis, the X-ray pattern of the lung and brain (computed tomography, and its function were monitored. Results. The hemispheric cortical level of injury of the brain with function compensation of its stem was predominantly determined in the controls; subcompensation and decompensation were ascertained in the ARDS groups. According to the proposed classification, these patients developed Stages 1 and 2 ARDS. When ARDS developed, there were rises in the level of extravascular lung fluid and pulmonary vascular permeability, a reduction in the oxygenation index (it was 6—12 hours later as compared with them, increases in a lung shunt and ICP; X-ray study revealed bilateral infiltrates in the absence of heart failure in Stage 2 ARDS. The correlation was positive between ICP and extravascular lung water index, and lung vascular permeability index (r>0.4;p<0.05. Conclusion. The studies have indicated that the classification proposed by V. V. Moroz and A. M. Golubev enables an early diagnosis of ARDS. One of its causes is severe brainstem injury that results in increased extravascular fluid in the lung due to its enhanced vascular permeability. The ICP value is a determinant in the diagnosis of secondary brain injuries. Key words: acute respiratory distress syndrome, extravascu-lar lung fluid, pulmonary vascular permeability, brain injury

    To examine the impact of a cognitive behaviour therapy (CBT) based intervention programme, termed the Coping Skills Group (CSG), on coping strategy use and emotional adjustment. Thirty-one individuals with TBI participated and a wait-list control design was used. The CSG ran twice a week, for 5 weeks and focused on developing adaptive coping skills for the management of emotional and adjustment issues. Following the CSG, the majority of participants subjectively reported that they had a better understanding of emotional issues and an improved ability to implement strategies to manage these issues. Adaptive coping, as measured on the Coping Scale for Adults, increased significantly immediately following intervention. However, no significant changes in anxiety, depression, self-esteem and psychosocial function were observed on the measures used. The results suggest that it may be possible to modify coping strategy use following brain injury, through CBT.

    Cases of primary brain-stem injury following closed head injury, verified by a CT scan, have been increasingly reported. However, most of them have other intracranial lesions in addition to the brain stem, resulting in a poor outcome. The CT scan of 200 cases with severe head injury-Araki's classification of types 3 and 4 - were analysed. Four cases out of them had localized brain-stem lesion without any other significant intracranial injury on a CT scan at the acute stage and had a better outcome than had previously been reported. In this analysis, these 4 cases were studied, and the CT findings, prognosis, and pathogenesis of the localized brain-stem injury were discussed. Follow-up CT of three cases, and taken one month or more later, showed diffuse cortical atrophy. This may indicate the presence of diffuse cerebral injury which could not be seen on CT scans at the acute stage. This atrophic change may also be related with the mechanism of posttraumatic conscious impairment and posttraumatic neurological deficits, such as mental symptoms and impairment of the higher cortical function. Shearing injury is a probable pathogenesis for this diffuse cortical injury. On the other hand, one case did not have any cortical atrophy on a follow-up CT scan. Therefore, this is a case with a localized primary brain-stem injury. Coup injury against the brain stem by a tentorial margin in a case with a small tentorial opening is a possible mechanism producing the localized brain-stem injury. (J.P.N.)

    Adverse childhood experiences are significant risk factors for physical and mental illnesses in adulthood. Traumatic brain injury/concussion is a challenging condition where pre-injury factors may affect recovery. The association between childhood adversity and traumatic brain injury/concussion has not been previously reviewed. The research question addressed is: What is known from the existing literature about the association between adverse childhood experiences and traumatic brain injury/concussion in adults? All original studies of any type published in English since 2007 on adverse childhood experiences and traumatic brain injury/concussion outcomes were included. The literature search was conducted in multiple electronic databases. Arksey and O'Malley and Levac et al.'s scoping review frameworks were used. Two reviewers independently completed screening and data abstraction. The review yielded six observational studies. Included studies were limited to incarcerated or homeless samples, and individuals at high-risk of or with mental illnesses. Across studies, methods for childhood adversity and traumatic brain injury/concussion assessment were heterogeneous. A positive association between adverse childhood experiences and traumatic brain injury occurrence was identified. The review highlights the importance of screening and treatment of adverse childhood experiences. Future research should extend to the general population and implications on injury recovery. Implications for rehabilitation Exposure to adverse childhood experiences is associated with increased risk of traumatic brain injury. Specific types of adverse childhood experiences associated with risk of traumatic brain injury include childhood physical abuse, psychological abuse, household member incarceration, and household member drug abuse. Clinicians and researchers should inquire about adverse childhood experiences in all people with traumatic brain injury as pre-injury health conditions can

    Primary and secondary brain injury may occur with severe traumatic brain injury. Secondary traumatic brain injury results in a more severe effect compared to primary traumatic brain injury. Therefore, prevention of secondary traumatic brain injury is necessary to obtain maximum therapeutic results and accurate determination of prognosis and better quality of life. This study aimed to determine accurate and noninvasive prognostic factors in patients with severe traumatic brain injury. It was a cohort study on 16 subjects. Intracranial pressure was monitored within the first 24 hours after traumatic brain injury. Examination of Brain-Derived Neurotrophic Factor (BDNF) and S100B protein were conducted four times. The severity of outcome was evaluated using Glasgow Outcome Scale (GOS) three months after traumatic brain injury. Intracranial pressure measurement performed 24 hours after traumatic brain injury, low S100B protein (6.16pg/ml) 48 hours after injury indicate good prognosis and were shown to be significant predictors (p<0.05) for determining the quality of GOS. The conclusion is patient with a moderate increase in intracranial pressure Intracranial pressure S100B protein, being inexpensive and non-invasive, can substitute BDNF and intracranial pressure measurements as a tool for determining prognosis 120 hours following traumatic brain injury.

  12. Default mode network as a potential biomarker of chemotherapy-related brain injury

    Chronic medical conditions and/or their treatments may interact with aging to alter or even accelerate brain senescence. Adult onset cancer, for example, is a disease associated with advanced aging and emerging evidence suggests a profile of subtle but diffuse brain injury following cancer chemotherapy. Breast cancer is currently the primary model for studying these “chemobrain” effects. Given the widespread changes to brain structure and function as well as the common impairment of integrated cognitive skills observed following breast cancer chemotherapy, it is likely that large-scale brain networks are involved. Default mode network (DMN) is a strong candidate considering its preferential vulnerability to aging and sensitivity to toxicity and disease states. Additionally, chemotherapy is associated with several physiologic effects including increased inflammation and oxidative stress that are believed to elevate toxicity in the DMN. Biomarkers of DMN connectivity could aid in the development of treatments for chemotherapy-related cognitive decline. For example, certain nutritional interventions could potentially reduce the metabolic changes (e.g. amyloid beta toxicity) associated with DMN disruption. PMID:24913897

    Full Text Available Children with traumatic brain injury are reported to have deficits in performance monitoring, but the mechanisms underlying these deficits are not well understood. Four performance monitoring hypotheses were explored by comparing how 28 children with traumatic brain injury and 28 typically developing controls (matched by age and sex performed on the stop-signal task. Control children slowed significantly more following incorrect than correct stop-signal trials, fitting the error monitoring hypothesis. In contrast, the traumatic brain injury group showed no performance monitoring difference with trial types, but significant group differences did not emerge, suggesting that children with traumatic brain injury may not perform the same way as controls.

    This narrative review will draw attention to the current limitations within the literature related to women following traumatic brain injury in order to stimulate discussion and inform future directions for research. There is a wide-ranging body of research about traumatic brain injury with the higher incidence of brain injury among males reflected in this body of work. As a result, the specific gendered issues facing women with traumatic brain injury are not as well understood. A search of electronic databases was conducted using the terms "traumatic brain injury", "brain injury", "women", "participation", "concussion" and "outcomes". The 36 papers revealed the following five themes (1) Relationships and life satisfaction; (2) Perception of self and body image; (3) Meaningful occupation; (4) Sexuality and sexual health; and (5) Physical function. Without research, which focuses specifically on the experience of women and girls with traumatic brain injury there is a risk that clinical care, policy development and advocacy services will not effectively accommodate them. Implications for rehabilitation Exploring the gendered issues women may experience following traumatic brain injury will enhance clinicians understanding of the unique challenges they face. Such information has the potential to guide future directions for research, policy, and practice. Screening women for hormonal imbalances such as hypopituitarism following traumatic brain injury is recommended as this may assist clinicians in addressing the far reaching implications in regard to disability, quality of life and mood. The growing literature regarding the cumulative effect of repeat concussions following domestic violence and women's increased risk of sport-related concussion may assist clinicians in advocating for appropriate rehabilitation and community support services.

  15. Traumatic brain injury and disturbed sleep and wakefulness.

    Baumann, Christian R

    2012-09-01

    Traumatic brain injury is a frequent condition worldwide, and sleep-wake disturbances often complicate the course after the injuring event. Current evidence suggests that the most common sleep-wake disturbances following traumatic brain injury include excessive daytime sleepiness and posttraumatic hypersomnia, that is, increased sleep need per 24 h. The neuromolecular basis of posttraumatic sleep pressure enhancement is not entirely clear. First neuropathological and clinical studies suggest that impaired hypocretin (orexin) signalling might contribute to sleepiness, but direct or indirect traumatic injury also to other sleep-wake modulating systems in the brainstem and the mesencephalon is likely. Posttraumatic insomnia may be less common than posttraumatic sleepiness, but studies on its frequency revealed conflicting results. Furthermore, insomnia is often associated with psychiatric comorbidities, and some patients with posttraumatic disruption of their circadian rhythm may be misdiagnosed as insomnia patients. The pathophysiology of posttraumatic circadian sleep disorders remains elusive; however, there is some evidence that reduced evening melatonin production due to traumatic brain damage may cause disruption of circadian regulation of sleep and wakefulness.

    Explosive aggressive behaviour is a significant clinical and medico-legal problem in patients suffering from head injury. However, experts in neuropsychiatry have proposed a specific category for this disorder: the o rganic aggressive syndrome: . The basic reason for proposing this diagnosis is that it describes the specificity of the violent conduct secondary to 'brain damage' with greater precision. Early diagnosis and treatment of the injury is critical. The impact of hnetium-99m-hexamethylpropuleneamine oxime (HMPAO) was examined for measuring brain damage in correlation to neuropsychological performance in patients with traumatic brain injury (TBI). We thus report the case of a twelve-year-old child with a history of CET, who presents with serious episodes of heteroaggressiveness and suggest the usefulness of single photon emission computerized tomography (SPECT) to establish the validity of this psychiatric diagnosis. The appearance of modern functional neuro-image techniques (SPECT) may help to increase the validity of clinical diagnoses in the field of psychiatry in general and of forensic psychiatry in particularly, as the related findings may be used as demarcation criteria to establish syndromic diagnoses (Au)

    Although hypothermic-targeted temperature management (HTTM) holds great potential for the treatment of traumatic brain injury (TBI), translation of the efficacy of hypothermia from animal models to TBI patientshas no entire consistency. This study aimed to find an ideal time window model in experimental rats which was more in accordance with clinical practice through the delayed HTTM intervention. Sprague-Dawley rats were subjected to unilateral cortical contusion injury and received therapeutic hypothermia at 15mins, 2 h, 4 h respectively after TBI. The neurological function was evaluated with the modified neurological severity score and Morris water maze test. The brain edema and morphological changes were measured with the water content and H&E staining. Brain sections were immunostained with antibodies against DCX (a neuroblast marker) and GFAP (an astrocyte marker). The apoptosis levels in the ipsilateral hippocampi and cortex were examined with antibodies against the apoptotic proteins Bcl-2, Bax, and cleaved caspase-3 by the immunofluorescence and western blotting. The results indicated that each hypothermia therapy group could improve neurobehavioral and cognitive function, alleviate brain edema and reduce inflammation. Furthermore, we observed that therapeutic hypothermia increased DCX expression, decreased GFAP expression, upregulated Bcl-2 expression and downregulated Bax and cleaved Caspase-3 expression. The above results suggested that HTTM at 2h or even at 4h post-injury revealed beneficial brain protection similarly, despite the best effect at 15min post-injury. These findings may provide relatively ideal time window models, further making the following experimental results more credible and persuasive. Copyright © 2017 Elsevier B.V. All rights reserved.

    In various animal and human studies, early administration of 17β-estradiol, a strong antioxidant, anti-inflammatory, and anti-apoptotic agent, significantly decreases the severity of injury in the brain associated with cell death. Estrone, the predominant estrogen in postmenopausal women, has been shown to be a promising neuroprotective agent. The overall goal of this project was to determine if estrone mitigates secondary injury following traumatic brain injury (TBI) in rats. Male rats were given either placebo (corn oil) or estrone (0.5 mg/kg) at 30 min after severe TBI. Using a controlled cortical impact device in rats that underwent a craniotomy, the right parietal cortex was injured using the impactor tip. Non-injured control and sham animals were also included. At 72 h following injury, the animals were perfused intracardially with 0.9% saline followed by 10% phosphate-buffered formalin. The whole brain was removed, sliced, and stained for TUNEL-positive cells. Estrone decreased cortical lesion volume (pcerebral cortical levels of TUNEL-positive staining (pprotective pathways such as the ERK1/2 and BDNF pathways, decreases ischemic secondary injury, and decreases apoptotic-mediated cell death. These results suggest that estrone may afford protection to those suffering from TBI.

    This study analyses factors associated with work-related traumatic brain injury (TBI), specifically in the construction industry in Ontario, Canada. This cross-sectional study utilized data extracted from the Ontario Workplace Safety and Insurance Board (WSIB) records indicating concussion/intracranial injury that resulted in days off work in 2004-2005. Analyses of 218 TBI cases revealed that falls were the most common cause of injury, followed by being struck by or against an object. Mechanisms of injury and the temporal profile of injury also varied by age. For instance, a significantly higher proportion of injuries occurred in the mornings for young workers compared to older workers. The results of this study provide important information for prevention of TBI which suggest important age-specific strategies for workers in the construction industry.

    Traumatic brain injury (TBI) is a significant biomedical problem among military personnel and civilians. There exists an urgent need to develop and refine biological measures of acute brain injury and chronic recovery after brain injury. Such measures "biomarkers" can assist clinicians in helping to define and refine the recovery process and developing treatment paradigms for the acutely injured to reduce secondary injury processes. Recent biomarker studies in the acute phase of TBI have highlighted the importance and feasibilities of identifying clinically useful biomarkers. However, much less is known about the subacute and chronic phases of TBI. We propose here that for a complex biological problem such as TBI, multiple biomarker types might be needed to harness the wide range of pathological and systemic perturbations following injuries, including acute neuronal death, neuroinflammation, neurodegeneration and neuroregeneration to systemic responses. In terms of biomarker types, they range from brain-specific proteins, microRNA, genetic polymorphism, inflammatory cytokines and autoimmune markers and neuro-endocrine hormones. Furthermore, systems biology-driven biomarkers integration can help present a holistic approach to understanding scenarios and complexity pathways involved in brain injury.

    The brain is dependent on glucose to meet its energy demands. We sought to evaluate the potential importance of impaired glucose transport by assessing the relationship between brain/serum glucose ratios, cerebral metabolic distress, and mortality after severe brain injury. We studied 46 consecutive comatose patients with subarachnoid or intracerebral hemorrhage, traumatic brain injury, or cardiac arrest who underwent cerebral microdialysis and intracranial pressure monitoring. Continuous insulin infusion was used to maintain target serum glucose levels of 80-120 mg/dL (4.4-6.7 mmol/L). General linear models of logistic function utilizing generalized estimating equations were used to relate predictors of cerebral metabolic distress (defined as a lactate/pyruvate ratio [LPR] ≥ 40) and mortality. A total of 5,187 neuromonitoring hours over 300 days were analyzed. Mean serum glucose was 133 mg/dL (7.4 mmol/L). The median brain/serum glucose ratio, calculated hourly, was substantially lower (0.12) than the expected normal ratio of 0.40 (brain 2.0 and serum 5.0 mmol/L). In addition to low cerebral perfusion pressure (P = 0.05) and baseline Glasgow Coma Scale score (P brain/serum glucose ratios below the median of 0.12 were independently associated with an increased risk of metabolic distress (adjusted OR = 1.4 [1.2-1.7], P brain/serum glucose ratios were also independently associated with in-hospital mortality (adjusted OR = 6.7 [1.2-38.9], P brain/serum glucose ratios, consistent with impaired glucose transport across the blood brain barrier, are associated with cerebral metabolic distress and increased mortality after severe brain injury.

    Full Text Available Mismatch negativity is generated automatically, and is an early monitoring indicator of neuronal integrity impairment and functional abnormality in patients with brain injury, leading to decline of cognitive function. Antipsychotic medication cannot affect mismatch negativity. The present study aimed to explore the relationships of mismatch negativity with neurocognition, daily life and social functional outcomes in patients after brain injury. Twelve patients with traumatic brain injury and 12 healthy controls were recruited in this study. We examined neurocognition with the Wechsler Adult Intelligence Scale-Revised China, and daily and social functional outcomes with the Activity of Daily Living Scale and Social Disability Screening Schedule, respectively. Mismatch negativity was analyzed from electroencephalogram recording. The results showed that mismatch negativity amplitudes decreased in patients with traumatic brain injury compared with healthy controls. Mismatch negativity amplitude was negatively correlated with measurements of neurocognition and positively correlated with functional outcomes in patients after traumatic brain injury. Further, the most significant positive correlations were found between mismatch negativity in the fronto-central region and measures of functional outcomes. The most significant positive correlations were also found between mismatch negativity at the FCz electrode and daily living function. Mismatch negativity amplitudes were extremely positively associated with Social Disability Screening Schedule scores at the Fz electrode in brain injury patients. These experimental findings suggest that mismatch negativity might efficiently reflect functional outcomes in patients after traumatic brain injury.

    Previous research has documented the feasibility of screening in emergency departments for adolescent suicide risk. This randomized trial examined the effectiveness of Teen Options for Change (TOC), an intervention for adolescents seeking general medical emergency services who screen positive for suicide risk. Participants were 49 youths, ages 14 to 19, seeking services for nonpsychiatric emergencies. They screened positive for suicide risk because of recent suicidal ideation, suicide attempt, or depression plus substance abuse. Youths were randomly assigned to the TOC intervention or to enhanced treatment as usual. Depression, hopelessness, and suicidal ideation were assessed at baseline and two months later. Adolescents assigned to TOC showed greater reductions in depression than adolescents assigned to the comparison group (Cohen's d=1.07, a large effect size). Hopelessness, suicidal ideation, and substance abuse outcomes trended positively (nonsignificantly), with small to moderate effect sizes. TOC may be a promising, brief intervention for adolescents seeking emergency services and at risk of suicide.

    Traumatic brain injury (TBI)-induced impairments in cerebral energy metabolism impede tissue repair and contribute to delayed functional recovery. Moreover, the transient alteration in brain glucose utilization corresponds to a period of increased vulnerability to the negative effects of a subsequent TBI. In order to better understand the factors contributing to TBI-induced central metabolic dysfunction, we examined the effect of single and repeated TBIs on brain insulin signalling. Here we show that TBI induced acute brain insulin resistance, which resolved within 7 days following a single injury but persisted until 28 days following repeated injuries. Obesity, which causes brain insulin resistance and neuroinflammation, exacerbated the consequences of TBI. Obese mice that underwent a TBI exhibited a prolonged reduction of Akt (also known as protein kinase B) signalling, exacerbated neuroinflammation (microglial activation), learning and memory deficits, and anxiety-like behaviours. Taken together, the transient changes in brain insulin sensitivity following TBI suggest a reduced capacity of the injured brain to respond to the neuroprotective and anti-inflammatory actions of insulin and Akt signalling, and thus may be a contributing factor for the damaging neuroinflammation and long-lasting deficits that occur following TBI. © 2016 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.

    The purpose of this study was to perform an umbrella review of meta-analyses of intervention studies designed to improve outcomes of pregnant or parenting teenagers. An extensive search retrieved nine reports which provided 21 meta-analyses analyses. Data were extracted by two reviewers. Methodological quality was assessed using the AMSTAR Instrument. Most effect sizes were small but high quality studies showed significant outcomes for reduced low birth weight (RR = 0.60), repeat pregnancies/births (OR = 0.47-0.62), maternal education (OR = 1.21-1.83), and maternal employment (OR = 1.26). Several parenting outcomes (parent-child teaching interaction post-intervention [SMD = -0.91] and at follow-up [SMD = -1.07], and parent-child relationship post-intervention [SMD = -0.71] and at follow-up [SMD = -0.90]) were significant, but sample sizes were very small. Many reports did not include moderator analyses. Behavioral interventions offer limited resources and occur too late to mitigate the educational and social disparities that precede teen pregnancy. Future intervention research and policies that redress the social determinants of early childbearing are recommended. Copyright © 2017 The Foundation for Professionals in Services for Adolescents.

    Brain edema is a major contributor to poor outcome and reduced quality of life after surgical brain injury (SBI). Although SBI pathophysiology is well-known, the correlation between cerebral edema and neurological deficits has not been thoroughly examined in the rat model of SBI. Thus, the purpose of this study was to determine the correlation between brain edema and deficits in standard sensorimotor neurobehavior tests for rats subjected to SBI. Sixty male Sprague-Dawley rats were subjected to either sham surgery or surgical brain injury via partial frontal lobectomy. All animals were tested for neurological deficits 24 post-SBI and fourteen were also tested 72 h after surgery using seven common behavior tests: modified Garcia neuroscore (Neuroscore), beam walking, corner turn test, forelimb placement test, adhesive removal test, beam balance test, and foot fault test. After assessing the functional outcome, animals were euthanized for brain water content measurement. Surgical brain injury resulted in significantly elevated frontal lobe brain water content 24 and 72 h after surgery compared to that of sham animals. In all behavior tests, significance was observed between sham and SBI animals. However, a correlation between brain water content and functional outcome was observed for all tests except Neuroscore. The selection of behavior tests is critical to determine the effectiveness of therapeutics. Based on this study's results, we recommend using beam walking, the corner turn test, the beam balance test, and the foot fault test since correlations with brain water content were observed at both 24 and 72 h post-SBI.

    Individuals living with acquired brain injury, typically caused by stroke or trauma, are far less likely to achieve recommended levels of physical activity for optimal health and well-being. With a growing number of people living with chronic disease and disability globally, self-management programs are seen as integral to the management of these conditions and the prevention of secondary health conditions. However, to date, there has been no systematic review of the literature examining the efficacy of self-management programs specifically on physical activity in individuals with acquired brain injury, whether delivered face-to-face or remotely. Therefore, the purpose of this review is to evaluate the efficacy of self-management programs in increasing physical activity levels in adults living in the community following acquired brain injury. The efficacy of remote versus face-to-face delivery was also examined. A systematic review of the literature was conducted. Electronic databases were searched. Two independent reviewers screened all studies for eligibility, assessed risk of bias, and extracted relevant data. Five studies met the inclusion criteria for this review. Studies were widely heterogeneous with respect to program content and delivery characteristics and outcomes, although all programs utilized behavioral change principles. Four of the five studies examined interventions in which physical activity was a component of a multifaceted intervention, where the depth to which physical activity specific content was covered, and the extent to which skills were taught and practiced, could not be clearly established. Three studies showed favorable physical activity outcomes following self-management interventions for stroke; however, risk of bias was high, and overall efficacy remains unclear. Although not used in isolation from face-to-face delivery, remote delivery via telephone was the predominant form of delivery in two studies with support for its inclusion

  14. Radiation-induced brain injury: A review

    Full Text Available Approximately 100,000 primary and metastatic brain tumor patients/year in the US survive long enough (> 6 months to experience radiation-induced brain injury. Prior to 1970, the human brain was thought to be highly radioresistant; the acute CNS syndrome occurs after single doses > 30 Gy; white matter necrosis occurs at fractionated doses > 60 Gy. Although white matter necrosis is uncommon with modern techniques, functional deficits, including progressive impairments in memory, attention, and executive function have become important, because they have profound effects on quality of life. Preclinical studies have provided valuable insights into the pathogenesis of radiation-induced cognitive impairment. Given its central role in memory and neurogenesis, the majority of these studies have focused on the hippocampus. Irradiating pediatric and young adult rodent brains leads to several hippocampal changes including neuroinflammation and a marked reduction in neurogenesis. These data have been interpreted to suggest that shielding the hippocampus will prevent clinical radiation-induced cognitive impairment. However, this interpretation may be overly simplistic. Studies using older rodents, that more closely match the adult human brain tumor population, indicate that, unlike pediatric and young adult rats, older rats fail to show a radiation-induced decrease in neurogenesis or a loss of mature neurons. Nevertheless, older rats still exhibit cognitive impairment. This occurs in the absence of demyelination and/or white matter necrosis similar to what is observed clinically, suggesting that more subtle molecular, cellular and/or microanatomic modifications are involved in this radiation-induced brain injury. Given that radiation-induced cognitive impairment likely reflects damage to both hippocampal- and non-hippocampal-dependent domains, there is a critical need to investigate the microanatomic and functional effects of radiation in various brain

    Full Text Available Abstract Background Current standard therapy for seizure prophylaxis in Neuro-surgical patients involves the use of Phenytoin (PHY. However, a new drug Levetiracetam (LEV is emerging as an alternate treatment choice. We aimed to conduct a meta-analysis to compare these two drugs in patients with brain injury. Methods An electronic search was performed in using Pubmed, Embase, and CENTRAL. We included studies that compared the use of LEV vs. PHY for seizure prophylaxis for brain injured patients (Traumatic brain injury, intracranial hemorrhage, intracranial neoplasms, and craniotomy. Data of all eligible studies was extracted on to a standardized abstraction sheet. Data about baseline population characteristics, type of intervention, study design and outcome was extracted. Our primary outcome was seizures. Results The literature search identified 2489 unduplicated papers. Of these 2456 papers were excluded by reading the abstracts and titles. Another 25 papers were excluded after reading their complete text. We selected 8 papers which comprised of 2 RCTs and 6 observational studies. The pooled estimate’s Odds Ratio 1.12 (95% CI = 0.34, 3.64 demonstrated no superiority of either drug at preventing the occurrence of early seizures. In a subset analysis of studies in which follow up for seizures lasted either 3 or 7 days, the effect estimate remained insignificant with an odds ratio of 0.96 (95% CI = 0.34, 2.76. Similarly, 2 trials reporting seizure incidence at 6 months also had insignificant pooled results while comparing drug efficacy. The pooled odds ratio was 0.96 (95% CI = 0.24, 3.79. Conclusions Levetiracetam and Phenytoin demonstrate equal efficacy in seizure prevention after brain injury. However, very few randomized controlled trials (RCTs on the subject were found. Further evidence through a high quality RCT is highly recommended.

    There has been substantial research on low birthweight (LBW) as a predictor of adverse educational and cognitive outcomes. LBW infants perform worse on cognitive battery tests compared to children born at normal birthweight; however, children exposed to similar risks do not all share the same experiences. The complex, interrelated factors responsible for poor cognitive and achievement performance vary for different populations, but researchers hypothesize that the home environment may influence the infants' long-term health outcomes. Examine the home environment as a moderator in the causal pathway from neonatal brain injury to school performance in a secondary analysis of a prospectively studied, geographically defined cohort from the Neonatal Brain Hemorrhage Study. The secondary analysis sample included 543 infants with birthweights of 501 to 2,000 g who were born consecutively in three community hospitals in New Jersey between 1984 and 1986. School performance at age 9 was measured by the Woodcock-Johnson Tests of Achievement. The home environment variables were tested and analyzed using multistep hierarchical regression modeling. A moderating effect between the variable neighborhood observations and brain injury was demonstrated for the outcome math score. The moderating relationship was found in the category of children without brain injury (β = 1.76, p = .005). There were statistically significant and potentially clinical meaningful models when looking at the home environmental variables as they relate to reading and math scores. The findings suggest that at least one variable within a LBW child's socio-environmental milieu can moderate the effects of perinatal brain injury on school performance outcomes.

    This study examines the role of condom use knowledge and attitudes, and parent-teen communication about sex and relationship quality on reports of condom use self-efficacy among rural, African American youth. Participants were 465 North Carolinian youth (10–14 years). Results indicated that greater condom use self-efficacy was predicted by greater knowledge of condom use (β = .206; p parent-teen communication about sex (β = .13; p parent-teen communication about sex and dating (β = .14; p parents and youth on measures related to parent-teen communication about sex. Findings call for interventions targeting improvement of condom use knowledge among early adolescents, as well as parent-teen communication about sex. In addition, given the low parent-teen agreement regarding sexual communication, parent-teen sexual communication is an important point of intervention. PMID:28461714

    Day-of-injury (DOI) brain lesion volumes in traumatic brain injury (TBI) patients are rarely used to predict long-term outcomes in the acute setting. The purpose of this study was to investigate the relationship between acute brain injury lesion volume and rehabilitation outcomes in patients with TBI at a level one trauma center. Patients with TBI who were admitted to our rehabilitation unit after the acute care trauma service from February 2009-July 2011 were eligible for the study. Demographic data and outcome variables including cognitive and motor Functional Independence Measure (FIM) scores, length of stay (LOS) in the rehabilitation unit, and ability to return to home were obtained. The DOI quantitative injury lesion volumes and degree of midline shift were obtained from DOI brain computed tomography scans. A multiple stepwise regression model including 13 independent variables was created. This model was used to predict postrehabilitation outcomes, including FIM scores and ability to return to home. A p value less than 0.05 was considered significant. Ninety-six patients were enrolled in the study. Mean age was 43 ± 21 years, admission Glasgow Coma Score was 8.4 ± 4.8, Injury Severity Score was 24.7 ± 9.9, and head Abbreviated Injury Scale score was 3.73 ± 0.97. Acute hospital LOS was 12.3 ± 8.9 days, and rehabilitation LOS was 15.9 ± 9.3 days. Day-of-injury TBI lesion volumes were inversely associated with cognitive FIM scores at rehabilitation admission (p = 0.004) and discharge (p = 0.004) and inversely associated with ability to be discharged to home after rehabilitation (p = 0.006). In a cohort of patients with moderate to severe TBI requiring a rehabilitation unit stay after the acute care hospital stay, DOI brain injury lesion volumes are associated with worse cognitive FIM scores at the time of rehabilitation admission and discharge. Smaller-injury volumes were associated with eventual discharge to home. Volumetric neuroimaging in the acute

    The neural underpinning of art creation can be gleaned following brain injury in professional artists. Any alteration to their artistic productivity, creativity, skills, talent, and genre can help understand the neural underpinning of art expression. Here, two world-renown and influential artists who sustained brain injury in World War I are the focus, namely the French artist Georges Braque and the Austrian artist Oskar Kokoschka. Braque is particularly associated with Cubism, and Kokoschka with Expressionism. Before enlisting, they were already well-known and highly regarded. Both were wounded in the battlefield where they lost consciousness and treated in European hospitals. Braque's injury was in the left hemisphere while Kokoschka's was in the right hemisphere. After the injury, Braque did not paint again for nearly a whole year while Kokoschka commenced his artistic works when still undergoing hospital treatment. Their post-injury art retained the same genre as their pre-injury period, and their artistic skills, talent, creativity, and productivity remained unchanged. The quality of their post-injury artworks remained highly regarded and influential. These neurological cases suggest widely distributed and diffuse neural control by the brain in the creation of art.

    "The International Conference on Behavioral Health and Traumatic Brain Injury" held at St. Joseph's Regional Medical Center in Paterson, NJ., from October 12 to 15, 2008, included a presentation on the novel assessment and treatment approach to mild traumatic brain injury (mTBI) by Philip A. DeFina, PhD, of the International Brain Research Foundation (IBRF). Because of the urgent need to treat a large number of our troops who are diagnosed with mTBI and post-traumatic stress disorder (PTSD), the conference was held to create a report for Congress titled "Recommendations to Improve the Care of Wounded Warriors NOW. March 12, 2009." This article summarizes and adds greater detail to Dr. DeFina's presentation on the current standard and novel ways to approach assessment and treatment of mTBI and PTSD. Pilot data derived from collaborative studies through the IBRF have led to the development of clinical and research protocols utilizing currently accepted, valid, and reliable neuroimaging technologies combined in novel ways to develop "neuromarkers." These neuromarkers are being evaluated in the context of an "Integrity-Deficit Matrix" model to demonstrate their ability to improve diagnostic accuracy, guide treatment programs, and possibly predict outcomes for patients suffering from traumatic brain injury.

    Fingolimod is a sphingosine-1-phosphate receptor modulator used for multiple sclerosis treatment and acts on cellular processes such as apoptosis, endothelial permeability, and inflammation. We hypothesized that fingolimod has a positive effect on alleviating preterm fetal brain injury. Sixteen pregnant rats were divided into four groups of four rats each. On gestational day 17, i.p. endotoxin was injected to induce fetal brain injury, followed by i.p. fingolimod (4 mg/kg maternal weight). Hysterotomy for preterm delivery was performed 6 h after fingolimod. The study groups included (i) vehicle controls (i.p. normal saline only); (ii) positive controls (endotoxin plus saline); (iii) saline plus fingolimod; and (iv) endotoxin plus fingolimod treatment. Brain tissues of the pups were dissected for evaluation of interleukin (IL)-6, caspase-3, and S100β on immunohistochemistry. Maternal fingolimod treatment attenuated endotoxin-related fetal brain injury and led to lower immunoreactions for IL-6, caspase-3, and S100β compared with endotoxin controls (P < 0.0001 for all comparisons). Antenatal maternal fingolimod therapy had fetal neuroprotective effects by alleviating preterm birth-related fetal brain injury with inhibitory effects on inflammation and apoptosis. © 2017 Japan Society of Obstetrics and Gynecology.

    Objective: To study the changes of interleukin-1 β (IL-1β), tumor necrosis factor α (TNFα) and interleukin-6 (IL-6) levels in brain and plasma after brain injury and to assess the relationship between the cytokine levels and injury severity in rats. Methods: A total of 51 male Wistar rats, weighing 280-340 g, were anesthetized with chloral hydrate (400 mg/kg body weight) through intraperitoneal injection and fixed on a stereotaxic instrument. Severe brain injury was created in 16 rats (severe injury group) and moderate brain injury in 18 rats (moderate injury group) by a fluid percussion model, and cytokine levels of IL-1β, TNFα and IL-6 were measured with biological assay. And sham operation was made on the other 17 rats (control group). Results: In the control group, the levels of IL-1β, TNFα and IL-6 were hardly detected in the cortex of the rats, but in the ipsilateral cortex of the rats in both injury groups, they increased obviously at 8 hours after injury. The increasing degree of these cytokines had no significant difference between the two injury groups. The levels of IL-6 in the plasma of all the rats increased slightly, whereas the levels of IL-1β and TNFα were undetectable. Conclusions: The increase of IL-1β, TNFα and IL-6 levels is closely related to brain injury. The increased cytokine levels in the central nervous system are not parallel to those in the peripheral blood. It suggests that inflammatory cytokines play important roles in the secondary neural damage after brain injury.

    Previous research suggests that traumatic brain injury (TBI) results in impairment of iconic memory abilities.We would like to acknowledge the contribution of Jeffrey D. Vantrease, who wrote the software program for the Iconic Memory procedure and measurement. This raises serious implications for brain injury rehabilitation. Most cognitive rehabilitation programs do not include iconic memory training. Instead it is common for cognitive rehabilitation programs to focus on attention and concentration skills, memory skills, and visual scanning skills.This study compared the iconic memory skills of brain-injury survivors and control subjects who all reached criterion levels of visual scanning skills. This involved previous training for the brain-injury survivors using popular visual scanning programs that allowed them to visually scan with response time and accuracy within normal limits. Control subjects required only minimal training to reach normal limits criteria. This comparison allows for the dissociation of visual scanning skills and iconic memory skills.The results are discussed in terms of their implications for cognitive rehabilitation and the relationship between visual scanning training and iconic memory skills.

    Full Text Available The shortage of available organ donors is a significant problem and various efforts have been made to avoid the loss of organ donors. Among these, extracorporeal membrane oxygenation (ECMO has been introduced to help support and manage potential donors. Many traumatic brain injury patients have healthy organs that might be eligible for donation for transplantation. However, the condition of a donor with a fatal brain injury may rapidly deteriorate prior to brain death determination; this frequently results in the loss of eligible donors. Here, we report the use of venoarterial ECMO to support a potential donor with a fatal brain injury before brain death determination, and thereby preserve donor organs. The patient successfully donated his liver and kidneys after brain death determination.

    Full Text Available Background: Acute respiratory distress syndrome (ARDS is one of the most important complications associated with traumatic brain injury (TBI. ARDS is caused by inflammation of the lungs and hypoxic damage with lung physiology abnormalities associated with acute respiratory distress syndrome. Aim of this study is to determine the epidemiology of ARDS and the prevalence of risk factors. Methods: This prospective study performed on patients with acute traumatic head injury hospitalization in the intensive care unit of the Shohaday-e Haftom-e-Tir Hospital (September 2012 to September 2013 done. About 12 months, the data were evaluated. Information including age, sex, education, employment, drug and alcohol addiction, were collected and analyzed. The inclusion criteria were head traumatic patients and exclusion was the patients with chest trauma. Questionnaire was designed with doctors supervision of neurosurgery. Then the collected data were analysis. Results: In this study, the incidence of ARDS was 23.8% and prevalence of metabolic acidosis was 31.4%. Most injury with metabolic acidosis was Subarachnoid hemorrhage (SAH 48 (60% and Subdural hemorrhage (SDH was Next Level with 39 (48% Correlation between Glasgow Coma Scale (GCS and Respiratory Distress Syndrome (ARDS were significantly decreased (P< 0.0001. The level of consciousness in patients with skull fractures significantly lower than those without fractures (P= 0.009 [(2.3±4.6 vs (4.02±7.07]. Prevalence of metabolic acidosis during hospitalization was 80 patients (31.4%. Conclusion: Acute respiratory distress syndrome is a common complication of traumatic brain injury. Management and treatment is essential to reduce the mortality. In this study it was found the age of patients with ARDS was higher than patients without complications. ARDS risk factor for high blood pressure was higher in men. Most victims were pedestrians. The most common injury associated with ARDS was SDH. Our analysis

    Objectives: To examine the published evidence on interventions to prevent softball related injuries among adults, and to encourage more epidemiologic research as a foundation for future softball injury prevention efforts. Methods: The authors reviewed literature identified from six electronic databases for studies on softball related injuries. The search was limited to studies written in the English language, published between 1970 and 2002, and involving adult populations. Research was excluded that evaluated baseball ("hard ball") related injuries or was aimed at injury treatment. Identified studies were categorized by study design. Intervention/prevention papers were evaluated further and described in detail. Results: The search strategy identified 39 studies specifically related to softball. Most studies were case reports/case series (n = 13) or descriptive studies (n = 11); only four were analytic or intervention/prevention studies. Studies collected data in a variety of ways, often without denominator data to permit calculation of injury rates. Studies also did not differentiate between slow or fast pitch softball activities and most did not mention the type of softball that was used. Conclusions: Surprisingly few studies exist on interventions to reduce injuries during softball, one of the most popular recreational sports in the US. Of the existing literature, much attention has been on sliding related injuries, which comprise only a segment of softball injuries. Basic epidemiologic studies describing the nature, severity, and risk factors for softball injuries in a variety of populations are needed, followed by additional intervention evaluation studies aimed at modifiable risk factors.

    Bipolar electrocautery is an effective and commonly used haemostatic technique but it may also cause iatrogenic brain trauma due to thermal injury and secondary inflammatory reactions. Progesterone has anti-inflammatory and neuroprotective actions in traumatic brain injury. However, its potential use in preventing iatrogenic brain trauma has not been explored. We conducted a pilot animal study to investigate the effect of systemic progesterone on brain cellular responses to electrocautery-induced injury. Adult male Sprague-Dawley rats received standardized bipolar electrocautery (40 W for 2 seconds) over the right cerebral cortex. The treatment group received progesterone intraperitoneally 2 hours prior to surgery; the control group received the drug vehicle only. Immunohistochemical studies showed that progesterone could significantly reduce astrocytic hypertrophy on postoperative day 1, 3 and 7, as well as macrophage infiltration on day 3. The number of astrocytes, however, was unaffected. Our findings suggest that progesterone should be further explored as a neuroprotective agent against electrocautery-induced or other forms of iatrogenic trauma during routine neurosurgical procedures. Future studies may focus on different dosing regimens, neuronal survival, functional outcome, and to compare progesterone with other agents such as dexamethasone. Copyright © 2013 Elsevier Ltd.

    To discuss the epidemiology, diagnosis and surgical treatment of cranial nerve injury following traumatic brain injury (TBI) for the sake of raising the clinical treatment of this special category of TBI. A retrospective analysis was made of 312 patients with cranial nerve injury among 3417 TBI patients, who were admitted for treatment in this hospital. A total of 312 patients (9.1%) involving either a single nerve or multiple nerves among the 12 pairs of cranial nerves were observed. The extent of nerve injury varied and involved the olfactory nerve (66 cases), optic nerve (78 cases), oculomotor nerve (56 cases), trochlear nerve (8 cases), trigeminal nerve (4 cases), abducent nerve (12 cases), facial nerve (48 cases), acoustic nerve (10 cases), glossopharyngeal nerve (8 cases), vagus nerve (6 cases), accessory nerve (10 cases) and hypoglossal nerve (6 cases). Imaging examination revealed skull fracture in 217 cases, complicated brain contusion in 232 cases, epidural haematoma in 194 cases, subarachnoid haemorrhage in 32 cases, nasal cerebrospinal fluid (CSF) leakage in 76 cases and ear CSF leakage in 8 cases. Of the 312 patients, 46 patients died; the mortality rate associated with low cranial nerve injury was as high as 73.3%. Among the 266 surviving patients, 199 patients received conservative therapy and 67 patients received surgical therapy; the curative rates among these two groups were 61.3% (122 patients) and 86.6% (58 patients), respectively. TBI-complicated cranial nerve injury is subject to a high incidence rate, a high mortality rate and a high disability rate. Our findings suggest that the chance of recovery may be increased in cases where injuries are amenable to surgical decompression. It is necessary to study all 12 pairs of cranial nerves systematically. Clinically, it is necessary to standardise surgical indications, operation timing, surgical approaches and methods for the treatment of TBI-complicated cranial nerve injury. 2010 Elsevier Ltd. All

  10. The Role of Medical Imaging in the Re-Characterization of Mild Traumatic Brain Injury Using Youth Sports as a Laboratory

    2016-01-01

    Full Text Available The short- and long-term impact of mild traumatic brain injury is an increasingly vital concern for both military and civilian personnel. Such injuries produce significant social and financial burdens, and necessitate improved diagnostic and treatment methods. Recent integration of neuroimaging and biomechanical studies in youth collision-sport athletes has revealed that significant alterations in brain structure and function occur even in the absence of traditional clinical markers of concussion. While task performance is maintained, athletes exposed to repetitive head accelerations exhibit structural changes to the underlying white matter, altered glial cell metabolism, aberrant vascular response and marked changes in functional network behavior. Moreover, these changes accumulate with accrued years of exposure, suggesting a cumulative trauma mechanism that may culminate in categorization as concussion and long-term neurological deficits. The goal of this review is to elucidate the role of medical imaging in re-characterizing traumatic brain injury, as a whole, to better identify at-risk individuals and improve the development of preventative and interventional approaches.

    2017-10-01

    The objectives of this study were to document the evolution of fatigue in the first year after traumatic brain injury (TBI), and to explore correlates of fatigue. Participants were 210 adults who were hospitalised following a TBI. They completed questionnaires 4, 8, and 12 months post-injury, including the Multidimensional Fatigue Inventory (MFI). Participants with severe TBI presented greater mental and physical fatigue, and reduced activity compared to participants with moderate TBI. For all MFI subscales except reduced motivation, the general pattern was a reduction of fatigue levels over time after mild TBI, an increase of fatigue after severe TBI, and stable fatigue after moderate TBI. Fatigue was significantly associated with depression, insomnia, cognitive difficulties, and pain at 4 months; the same variables and work status at 8 months; and depression, insomnia, cognitive difficulties, and work status at 12 months. These findings suggest that injury severity could have an impact on the course of fatigue in the first year post-TBI. Depression, insomnia, and cognitive difficulties remain strong correlates of fatigue, while for pain and work status the association with fatigue evolves over time. This could influence the development of intervention strategies for fatigue, implemented at specific times for each severity subgroup.

    Full Text Available Traumatic brain injury (TBI is a significant public health concern, and can be especially disruptive in children, derailing on-going neuronal maturation in periods critical for cognitive development. There is considerable heterogeneity in post-injury outcomes, only partially explained by injury severity. Understanding the time course of recovery, and what factors may delay or promote recovery, will aid clinicians in decision-making and provide avenues for future mechanism-based therapeutics. We examined regional changes in brain volume in a pediatric/adolescent moderate-severe TBI (msTBI cohort, assessed at two time points. Children were first assessed 2–5 months post-injury, and again 12 months later. We used tensor-based morphometry (TBM to localize longitudinal volume expansion and reduction. We studied 21 msTBI patients (5 F, 8–18 years old and 26 well-matched healthy control children, also assessed twice over the same interval. In a prior paper, we identified a subgroup of msTBI patients, based on interhemispheric transfer time (IHTT, with significant structural disruption of the white matter (WM at 2–5 months post injury. We investigated how this subgroup (TBI-slow, N = 11 differed in longitudinal regional volume changes from msTBI patients (TBI-normal, N = 10 with normal WM structure and function. The TBI-slow group had longitudinal decreases in brain volume in several WM clusters, including the corpus callosum and hypothalamus, while the TBI-normal group showed increased volume in WM areas. Our results show prolonged atrophy of the WM over the first 18 months post-injury in the TBI-slow group. The TBI-normal group shows a different pattern that could indicate a return to a healthy trajectory.

    After traumatic injury, the brain undergoes a prolonged period of degenerative change that is paradoxically accompanied by cognitive recovery. The spatiotemporal pattern of atrophy and the specific relationships of atrophy to cognitive changes are ill understood. The present study used tensor-based morphometry and neuropsychological testing to examine brain volume loss in 17 traumatic brain injury (TBI) patients and 13 controls over a 4-year period. Patients were scanned at 2 months, 1 year, and 4 years post-injury. High-dimensional warping procedures were used to create change maps of each subject's brain for each of the two intervals. TBI patients experienced volume loss in both cortical areas and white matter regions during the first interval. We also observed continuing volume loss in extensive regions of white matter during the second interval. Neuropsychological correlations indicated that cognitive tasks were associated with subsequent volume loss in task-relevant regions. The extensive volume loss in brain white matter observed well beyond the first year post-injury suggests that the injured brain remains malleable for an extended period, and the neuropsychological relationships suggest that this volume loss may be associated with subtle cognitive improvements.

    Traumatic injury to the brain is one of the leading causes of injury-related death or disability. Brain response to injury is orchestrated by cytokines, such as interleukin (IL)-6, but the full repertoire of responses involved is not well known. We here report the results obtained with microarrays...... in wild-type and IL-6 knockout mice subjected to a cryolesion of the somatosensorial cortex and killed at 0, 1, 4, 8 and 16 days post-lesion. Overall gene expression was analyzed by using Affymetrix genechips/oligonucleotide arrays with approximately 12,400 probe sets corresponding to approximately 10...... in the initial tissue injury and later regeneration of the parenchyma. IL-6 deficiency showed a dramatic effect in the expression of many genes, especially in the 1 day post-lesion timing, which presumably underlies the poor capacity of IL-6 knockout mice to cope with brain damage. The results highlight...

  2. MICROGLIA ACTIVATION AS A BIOMARKER FOR TRAUMATIC BRAIN INJURY

    Directory of Open Access Journals (Sweden)

    2013-03-01

    Full Text Available Traumatic brain injury (TBI has become the signature wound of wars in Afghanistan and Iraq. Injury may result from a mechanical force, a rapid acceleration-deceleration movement, or a blast wave. A cascade of secondary cell death events ensues after the initial injury. In particular, multiple inflammatory responses accompany TBI. A series of inflammatory cytokines and chemokines spreads to normal brain areas juxtaposed to the core impacted tissue. Among the repertoire of immune cells involved, microglia is a key player in propagating inflammation to tissues neighboring the core site of injury. Neuroprotective drug trials in TBI have failed, likely due to their sole focus on abrogating neuronal cell death and ignoring the microglia response despite these inflammatory cells’ detrimental effects on the brain. Another relevant point to consider is the veracity of results of animal experiments due to deficiencies in experimental design, such as incomplete or inadequate method description, data misinterpretation and reporting may introduce bias and give false-positive results. Thus, scientific publications should follow strict guidelines that include randomization, blinding, sample-size estimation and accurate handling of all data (Landis et al., 2012. A prolonged state of inflammation after brain injury may linger for years and predispose patients to develop other neurological disorders, such as Alzheimer’s disease. TBI patients display progressive and long-lasting impairments in their physical, cognitive, behavioral, and social performance. Here, we discuss inflammatory mechanisms that accompany TBI in an effort to increase our understanding of the dynamic pathological condition as the disease evolves over time and begin to translate these findings for defining new and existing inflammation-based biomarkers and treatments for TBI.

    BACKGROUND: Learning and memory damage is one of the most permanent and the severest symptoms of traumatic brain injury; it can seriously influence the normal life and work of patients. Some research has demonstrated that cognitive disorder is closely related to nicotine cholinergic receptors, N-methyl-D aspartate receptors, neural cell adhesion molecule, and brain-derived neurotrophic factor. OBJECTIVE: To summarize the cognitive disorder and changes in nicotine cholinergic receptors, N-methyl-D aspartate receptors, neural cell adhesion molecule, and brain-derived neurotrophic factor following brain injury. RETRIEVAL STRATEGY: A computer-based online search was conducted in PUBMED for English language publications containing the key words "brain injured, cognitive handicap, acetylcholine, N-methyl-D aspartate receptors, neural cell adhesion molecule, brain-derived neurotrophic factor" from January 2000 to December 2007. There were 44 papers in total. Inclusion criteria: ① articles about changes in nicotine cholinergic receptors, N-methyl-D aspartate receptors, neural cell adhesion molecule, and brain-derived neurotrophic factor following brain injury; ② articles in the same researching circle published in authoritative journals or recently published. Exclusion criteria: duplicated articles.LITERATURE EVALUATION: References were mainly derived from research on changes in these four factors following brain injury. The 20 included papers were clinical or basic experimental studies. DATA SYNTHESIS: After craniocerebral injury, changes in these four factors in brain were similar to those during recovery from cognitive disorder, to a certain degree. Some data have indicated that activation of nicotine cholinergic receptors, N-methyl-D aspartate receptors, neural cell adhesion molecule, and brain-derived neurotrophic factor could greatly improve cognitive disorder following brain injury. However, there are still a lot of questions remaining; for example, how do these

    Despite the increasing rate of survival from hypoxic-ischemic brain injury (HIBI), there is a paucity of evidence on the long-term functional outcomes after inpatient rehabilitation among these nontrauma patients compared to patients with traumatic brain injury (TBI). To compare functional and psychosocial outcomes of patients with HIBI to those of case-matched patients with TBI 4-11 years after brain insult. Retrospective, matched case-controlled study. Data at the time of rehabilitation admission and discharge were collected as part of a larger acquired brain injury (ABI) database at Toronto Rehabilitation Institute (TRI) between 1999 and 2009. This study consisted of 11 patients with HIBI and 11 patients with TBI that attended the neuro-rehabilitation day program at TRI during a similar time frame and were matched on age, admission Functional Independence Measure (FIM) scores, and acute care length of stay (ALOS). At 4-11 years following brain insult, patients were reassessed using the FIM, Disability Rating Scale (DRS), Personal Health Questionnaire Depression Scale (PHQ-9), and the Mayo-Portland Adaptability Inventory 4 (MPAI-4). At follow-up, patients with HIBI had significantly lower FIM motor and cognitive scores than patients with TBI (75.3 ± 20.6 versus 88.1 ± 4.78, P MPAI-4 at follow-up (P < .05). The study results suggest that patients with HIBI achieve less long-term functional improvements compared to patients with TBI. Further research is warranted to compare the components of inpatient rehabilitation while adjusting for demographics and clinical characteristics between these 2 groups of patients. III.

    Traumatic brain injury is the leading cause of disability in young adults aged 15 to 45 years. Mobility limitations are prevalent, and range in severity from interfering with basic day-to-day tasks to restricting participation in higher level social, leisure, employment and sporting activities. Despite the prevalence and severity of physical impairments, such as poor balance and spasticity, the main contributor to mobility limitations following traumatic brain injury is low muscle power generation. Strengthening exercises that are performed quickly are termed 'ballistic' as they are aimed at improving the rate of force production and, hence, muscle power. This is compared with conventional strength training, which is performed slowly and aims to improve maximum force production, yet has limited impact on mobility. In people recovering from traumatic brain injury: (1) is a 12-week ballistic strength-training program targeting the three muscle groups critical for walking more effective than usual care at improving mobility, strength and balance; and (2) does improved mobility translate to better health-related quality of life? A prospective, multi-centre, randomised, single-blind trial with concealed allocation will be conducted. Participants will be patients with a neurologically based movement disorder affecting mobility as a result of traumatic brain injury. Patients will be recruited during the acute phase of rehabilitation (n=166), from brain injury units in large metropolitan hospitals in Melbourne and Sydney, Australia. For 12 weeks, participants in the experimental group will have three 60-minute sessions of usual physiotherapy intervention replaced by three 60-minute sessions of strength training (ballistic strength, gait). The three key muscle groups responsible for forward propulsion will be targeted: ankle plantarflexors, hip flexors and the hip extensors. Initial loads will be low, to facilitate high contraction velocities. Progression to higher loads

    In previous studies, collagen based matrices have been implanted into the site of lesion in different models of brain injury. We hypothesized that semisynthetic collagen matrix can have neuroprotective function in the setting of traumatic brain injury. Rats were subjected to sham injury or controlled cortical impact. They either received extracellular matrix graft (DuraGen) over the injury site or did not receive any graft and underwent beam balance/beam walking test at post injury days 1-5 and Morris water maze at post injury days 14-18. Animals were sacrificed at day 18 for tissue analysis. Collagen matrix implantation in injured rats did not affect motor function (beam balance test: p = 0.627, beam walking test: p = 0.921). However, injured group with collagen matrix had significantly better spatial memory acquisition (p < 0.05). There was a significant reduction in lesion volume, as well as neuronal loss in CA1 (p < 0.001) and CA3 (p < 0.05) regions of the hippocampus in injured group with collagen matrix (p < 0.05). Collagen matrix reduces contusional lesion volume, neuronal loss, and cognitive deficit after traumatic brain injury. Further studies are needed to demonstrate the mechanisms of neuroprotection by collagen matrix.

    In this study, the case of a patient who developed artistic ability following a traumatic brain injury is reported. The subject was a 49-year-old male who suffered brain injury at the age of 44 due to an accidental fall. At age 48, he began drawing with great enthusiasm and quickly developed a personal style with his own biomorphic iconography. At first, his drawing was restricted to realistic reproductions of photographs of buildings, but his style of drawing changed and became more personal and expressionistic over the following 6 months.

    The purpose of this case report was to describe the use of hippotherapy with a boy who sustained a brain injury. A 13-year-old boy, 6 months after traumatic brain injury received 12 physical therapy sessions, which included hippotherapy. Improvements were noted in balance, strength, gross motor skills, gait speed, functional mobility, and reported participation. Hippotherapy used with a 13-year-old boy after traumatic brain injury may have had a positive effect in the body structure, activity, and participation domains.

    Purpose: The purpose of the present study was to evaluate the prophylactic effect of hyperbaric oxygen (HBO) therapy for radiation-induced brain injury in patients with brain metastasis treated with stereotactic radiosurgery (SRS). Methods and Materials: The data of 78 patients presenting with 101 brain metastases treated with SRS between October 1994 and September 2003 were retrospectively analyzed. A total of 32 patients with 47 brain metastases were treated with prophylactic HBO (HBO group), which included all 21 patients who underwent subsequent or prior radiotherapy and 11 patients with common predictors of longer survival, such as inactive extracranial tumors and younger age. The other 46 patients with 54 brain metastases did not undergo HBO (non-HBO group). Radiation-induced brain injuries were divided into two categories, white matter injury (WMI) and radiation necrosis (RN), on the basis of imaging findings. Results: Radiation-induced brain injury occurred in 5 lesions (11%) in the HBO group (2 WMIs and 3 RNs) and in 11 (20%) in the non-HBO group (9 WMIs and 2 RNs). The WMI was less frequent for the HBO group than for the non-HBO group (p = 0.05), although multivariate analysis by logistic regression showed that WMI was not significantly correlated with HBO (p = 0.07). The 1-year actuarial probability of WMI was significantly better for the HBO group (2%) than for the non-HBO group (36%) (p < 0.05). Conclusions: The present study showed a potential value of prophylactic HBO for Radiation-induced WMIs, which justifies further evaluation to confirm its definite benefit

    Full Text Available Traumatic brain injury (TBI, defined as an alteration in brain functions caused by an external force, is responsible for high morbidity and mortality around the world. It is important to identify and treat TBI victims as early as possible. Tracking and monitoring TBI with neuroimaging technologies, including functional magnetic resonance imaging (fMRI, diffusion tensor imaging (DTI, positron emission tomography (PET, and high definition fiber tracking (HDFT show increasing sensitivity and specificity. Classical electrophysiological monitoring, together with newly established brain-on-chip, cerebral microdialysis techniques, both benefit TBI. First generation molecular biomarkers, based on genomic and proteomic changes following TBI, have proven effective and economical. It is conceivable that TBI-specific biomarkers will be developed with the combination of systems biology and bioinformation strategies. Advances in treatment of TBI include stem cell-based and nanotechnology-based therapy, physical and pharmaceutical interventions and also new use in TBI for approved drugs which all present favorable promise in preventing and reversing TBI.

    2017-05-19

    Traumatic brain injury (TBI) continues to be the leading cause of death and acquired disability in young children and adolescents, due to blunt or penetrating trauma, the latter being less common but more lethal. Penetrating brain injury (PBI) has not been studied extensively, mainly reported as case reports or case series, due to the assumption that both types of brain injury have common pathophysiology and consequently common management. However, recommendations and guidelines for the management of PBI differ from those of blunt TBI in regards to neuroimaging, intracranial pressure (ICP) monitoring, and surgical management including those pertaining to vascular injury. PBI was one of the exclusion criteria in the second edition of guidelines for the acute medical management of severe TBI in infants, children, and adolescents that was published in 2012 (it is referred to as "pediatric guidelines" in this review). Many reviews of TBI do not differentiate between the mechanisms of injury. We present an overview of PBI, its presenting features, epidemiology, and causes as well as an analysis of case series and the conclusions that may be drawn from those and other studies. More clinical trials specific to penetrating head injuries in children, focusing mainly on pathophysiology and management, are needed. The term PBI is specific to penetrating injury only, whereas TBI, a more inclusive term, describes mainly, but not only, blunt injury.

    Objective: Adverse cognitive, emotional and behavioural sequelae of Traumatic Brain Injury (TBI) are commonly noted by family members. These sequelae can adversely impact on marital and family relationships. The aim of this study is to examine marital and relationship satisfaction following a TBI amongst patients and partners. Design: A questionnaire based postal survey was used to investigate relationship and marital satisfaction. Participants: Thirty four participants (14 male; 20 female), ranging in age from 25-68 years ( = 44 years, SD 11 years), took part in this study. Sixteen had sustained a TBI and eighteen were partners of patients with TBI. Participants with TBI who were inpatients at the National Rehabilitation Hospital (NRH) and their partners were invited to participate in the study. Outcome Measures: The Marital Satisfaction Questionnaire (MSI-R) was used to examine marital and relationship satisfaction. Results: Both patients and partners reported relationship difficulties following brain injury (z = -3.078, p < .05 patients; z = 2.699, p < .05 partners). Conclusion: This study highlights the significant impact of TBI on relationships for both the TBI survivor and their partners. Implications for interventions in neuropsychological rehabilitation are discussed.

    Aging may be an important factor affecting brain injury by intracerebral hemorrhage (ICH). In the present study, we investigated the responses of glial cells and monocytes to intracerebral hemorrhage in normal and aged rats. ICH was induced by microinjecting autologous whole blood (15 microL) into the striatum of young (4 month old) and aged (24 month old) Sprague-Dawley rats. Age-dependent relations of brain tissue damage with glial and macrophageal responses were evaluated. Three days after ICH, activated microglia/macrophages with OX42-positive processes and swollen cytoplasm were more abundantly distributed around and inside the hemorrhagic lesions. These were more dramatic in aged versus the young rats. Western blot and immunohistochemistry analyses showed that the expression of interleukin-1beta protein after ICH was greater in aged rats, whereas the expression of GFAP and ciliary neurotrophic factor protein after ICH was significantly lower in aged rats. These results suggest that ICH causes more severe brain injury in aged rats most likely due to overactivation of microglia/macrophages and concomitant repression of reactive astrocytes.

    Traumatic brain injury is a leading cause of death and disability in the United States. In survivors, traumatic brain injury remains a leading contributor to long-term disability and results in many patients being admitted to skilled nursing facilities for postacute care. Despite this very large population of traumatic brain injury patients, very little is known about the long-term outcomes of traumatic brain injury survivors, including rates of discharge to home or risk of death in long-term nursing facilities. We hypothesized that patient demographics and functional status influence outcomes of patients with traumatic brain injury admitted to skilled nursing facilities. We conducted a retrospective cohort study of Medicare fee-for-service beneficiaries aged 65 and older discharged alive and directly from hospital to a skilled nursing facility between 2011 and 2014 using the prospectively maintained Federal Minimum Data Set combined with Medicare claims data and the Centers for Medicare and Medicaid Services Vital Status files. Records were reviewed for demographic and clinical characteristics at admission to the skilled nursing facility, including age, sex, cognitive function, ability to communicate, and motor function. Activities of daily living were reassessed at discharge to calculate functional improvement. We used robust Poisson regression with skilled nursing facility fixed effects to calculate relative risks and 99% confidence intervals for mortality and functional improvement associated with the demographic and clinical characteristics present at admission. Linear regression was used to calculate adjusted mean duration of stay. Overall, 87,292 Medicare fee-for-service beneficiaries with traumatic brain injury were admitted to skilled nursing facilities. The mean age was 84 years, with 74% of patients older than age 80. Generally, older age, male sex, and poor cognitive or functional status at admission to a skilled nursing facility were associated with

    Mild traumatic brain injury (mTBI) represents a major health problem in civilian populations as well as among the military service members due to (1) lack of effective treatments, and (2) our incomplete understanding about the progression of secondary cell injury cascades resulting in neuronal cell death due to deficient cellular energy metabolism and damaged mitochondria. The aim of this study was to identify and delineate the mitochondrial targeted genes responsible for altered brain energy metabolism in the injured brain. Rats were either grouped into naïve controls or received lateral fluid percussion brain injury (2-2.5 atm) and followed up for 7 days. Rats were either grouped into naïve controls or received lateral fluid percussion brain injury (2-2.5 atm) and followed for 7 days. The severity of brain injury was evaluated by the neurological severity scale-revised (NSS-R) at 3 and 5 days post TBI and immunohistochemical analyses at 7 days post TBI. The expression profiles of mitochondrial-targeted genes across the hippocampus from TBI and naïe rats were also examined by oligo-DNA microarrays. NSS-R scores of TBI rats (5.4 ± 0.5) in comparison to naïe rats (3.9 ± 0.5) and H and E staining of brain sections suggested a mild brain injury. Bioinformatics and systems biology analyses showed 31 dysregulated genes, 10 affected canonical molecular pathways including a number of genes involved in mitochondrial enzymes for oxidative phosphorylation, mitogen-activated protein Kinase (MAP), peroxisome proliferator-activated protein (PPAP), apoptosis signaling, and genes responsible for long-term potentiation of Alzheimer's and Parkinson's diseases. Our results suggest that dysregulated mitochondrial-focused genes in injured brains may have a clinical utility for the development of future therapeutic strategies aimed at the treatment of TBI.

    Traumatic brain injury (TBI) is a major cause of death and disability worldwide. Unfavorable TBI outcomes result from primary mechanical injuries to the brain and ensuing secondary non-mechanical injuries that are not limited to the brain. Our genome-wide association study of Drosophila melanogaster revealed that the probability of death following TBI is associated with single nucleotide polymorphisms in genes involved in tissue barrier function and glucose homeostasis. We found that TBI causes intestinal and blood–brain barrier dysfunction and that intestinal barrier dysfunction is highly correlated with the probability of death. Furthermore, we found that ingestion of glucose after a primary injury increases the probability of death through a secondary injury mechanism that exacerbates intestinal barrier dysfunction. Our results indicate that natural variation in the probability of death following TBI is due in part to genetic differences that affect intestinal barrier dysfunction.

    Repeated head injuries are a major public health concern both for athletes, and members of the police and armed forces. There is ample experimental and clinical evidence that there is a period of enhanced vulnerability to subsequent injury following head trauma. Injuries that occur close together in time produce greater cognitive, histological, and behavioral impairments than do injuries separated by a longer period. Traumatic brain injuries alter cerebral glucose metabolism and the resolution of altered glucose metabolism may signal the end of the period of greater vulnerability. Here, we injured mice either once or twice separated by three or 20days. Repeated injuries that were separated by three days were associated with greater axonal degeneration, enhanced inflammatory responses, and poorer performance in a spatial learning and memory task. A single injury induced a transient but marked increase in local cerebral glucose utilization in the injured hippocampus and sensorimotor cortex, whereas a second injury, three days after the first, failed to induce an increase in glucose utilization at the same time point. In contrast, when the second injury occurred substantially later (20days after the first injury), an increase in glucose utilization occurred that paralleled the increase observed following a single injury. The increased glucose utilization observed after a single injury appears to be an adaptive component of recovery, while mice with 2 injuries separated by three days were not able to mount this response, thus this second injury may have produced a significant energetic crisis such that energetic demands outstripped the ability of the damaged cells to utilize energy. These data strongly reinforce the idea that too rapid return to activity after a traumatic brain injury can induce permanent damage and disability, and that monitoring cerebral energy utilization may be a tool to determine when it is safe to return to the activity that caused the initial

    Objective: To analyze the dynamic change of serum protein S100b in patients with traumatic brain injury and its clinical value in assessing brain damage. Methods: According to Glasgow coma scale (GCS), 102 cases of traumatic brain injury were divided into mild brain injury group (GCS≥13, n=31, Group A), moderate brain injury group (8brain injury group (GCS≤8, n=34, Group C). Serial S100b concentrations were analyzed by enzyme-linked immunosorbent assay (ELISA) in blood samples taken on admission, 12 h, 24 h, 48 h, 72 h and 7 days after traumatic brain injury. Results: The severe brain injury group showed significantly higher concentration of serum S100b, with earlier increase and longer duration, than the mild and moderate brain injury groups. The patients with higher S100b exhibited lower GCS scores and poor clinical prognosis. The increase in S100b could emerge before clinical image evidence indicated so. Conclusions: Serum S100b can be used as a sensitive index for assessment and prediction of traumatic brain injury severity and prognosis.

    Child injuries represent an important public health problem. The aim of this paper is to review the current scientific knowledge on interventions designed to prevent child injuries. The current state of knowledge in this area was assessed by means of a specific method involving a review of literature reviews and a classification of health promotion interventions identified in these reviews (rapid reviews). We found a large number of effective or promising programmes devoted to the prevention of the most common child injuries: drowning, burns, falls, poisoning, electrocution, sports and leisure injuries. Some interventions are based on environmental measures, while others are educational or use law and regulatory processes. Some are primary prevention measures, others are secondary prevention measures, while others are multidimensional and can effectively reduce several types of injuries. For example, home safety education and provision of safety equipment, or home-based parenting interventions, can have an impact on injury rates. These findings present a number of limitations due to the marked diversity of the quality of the documents reviewed. It should also be stressed that interventions that are not listed in this article are not necessarily ineffective: they may simply lack a rigorous evaluation enabling them to be identified in our review.

    To evaluate the safety, feasibility and effectiveness of a dual-task home-based rehabilitation programme on balance impairments among adult patients with acquired brain injury. Single-blind, randomized controlled pilot study. Single rehabilitation centre. Sixteen participants between 12 and 18 months post-acquired brain injury with balance impairments and a score task home-based programme six days a week for seven weeks. The primary outcome measure was the Balance Evaluation System Test; secondary measures were the Activities-specific Balance Confidence Scale and Goal Attainment Scaling. At the end of the pilot study, the intervention group showed significantly greater improvement in Balance Evaluation System Test scores (17.87, SD 6.05) vs. the control group (5.5, SD 3.53; P = 0.008, r = 0.63). There was no significant difference in improvement in Activities-specific Balance Confidence Scale scores between the intervention group (25.25, SD 25.51) and the control group (7.00, SD 14.73; P = 0.11, r = 0.63). There was no significant improvement in Goal Attainment Scaling scores in the intervention (19.37, SD 9.03) vs. the control group (16.28, SD 6.58; P = 0.093, r = 0.63). This pilot study shows the safety, feasibility and short-term benefit of a dual-task home-based rehabilitation programme to improve balance control in patients with acquired brain injury. A sample size of 26 participants is required for a definitive study.

    Different theoretical frameworks support the use of interactive websites to promote sexual health. Although several Web-based interventions have been developed to address sexual risk taking among young people, no evaluated interventions have attempted to foster behavior change through moderated interaction among a virtual network of adolescents (who remain anonymous to one another) and health professionals. The objective was to conduct a summative process evaluation of TeensTalkHealth, an interactive sexual health website designed to promote condom use and other healthy decision making in the context of romantic and sexual relationships. Evaluation data were obtained from 147 adolescents who participated in a feasibility and acceptability study. Video vignettes, teen-friendly articles, and other content served as conversation catalysts between adolescents and health educators on message boards. Adolescents' perceptions that the website encouraged condom use across a variety of relationship situations were very high. Almost 60% (54/92, 59%) of intervention participants completed two-thirds or more of requested tasks across the 4-month intervention. Adolescents reported high levels of comfort, perceived privacy, ease of website access and use, and perceived credibility of health educators. Potential strategies to enhance engagement and completion of intervention tasks during future implementations of TeensTalkHealth are discussed, including tailoring of content, periodic website chats with health educators and anonymous peers, and greater incorporation of features from popular social networking websites. TeensTalkHealth is a feasible, acceptable, and promising approach to complement and enhance existing services for youth.

    Radiation brain injury, including functional disturbances or morphological changes (brain atrophy, periventricular lucencies or ventricular dilatation), were studied by CT in patients with primary intracranial neoplasms who were followed-up for at least 5 months after receiving radiotherapy. Each of 33 patients with medulloblastoma, pinealregion tumor or malignant lymphoma received a total dose of 40-61 Gy by conventional fractionation using a whole brain irradiation field boosted by a localized field. Of these patients, 19 (58%) developed radiation brain injury. It was concluded that the volume-dose was one of the most important factors influencing the development of radiation brain injury. Age at the time of radiotherapy and time of follow-up after the treatment were also considered to be important factors. (author)

    The hidden nature of brain injury means that it is often difficult for people to understand the sometimes challenging behaviors that individuals exhibit. The misattribution of these behaviors may lead to a lack of consideration and public censure if the individual is seen as simply misbehaving. The aim of this study was to explore the impact of visual cues indicating the presence or absence of brain injury on prejudice, desire for social interaction, and causal attributions of nursing and computing science students. An independent-groups design was employed in this research, which recruited 190 first-year nursing students and 194 first-year computing science students from a major university in Belfast, UK. A short passage describing an adolescent's behavior after a brain injury, together with one of three images portraying a young adolescent with a scar, a head dressing, or neither of these, was given to participants. They were then asked to answer questions relating to prejudice, social interaction, locus of control, and causal attributions. The attributional statements suggested that the character's behavior could be the result of brain injury or adolescence. Analysis of variance demonstrated a statistically significant difference between the student groups, where nursing students (M = 45.17, SD = 4.69) desired more social interaction with the fictional adolescent than their computer science peers (M = 38.64, SD = 7.69). Further, analysis of variance showed a main effect of image on the attributional statement that described adolescence as a suitable explanation for the character's lack of self-confidence. Attributions of brain injury were influenced by the presence of a visible but potentially specious indicator of injury. This suggests that survivors of brain injury who do not display any outward indicator may receive less care and face expectations to behave in a manner consistent with the norms of society. If their injury does not allow them to meet with

    The past 50 years have been a period of exciting progress in neuropsychological research on traumatic brain injury (TBI). Neuropsychologists and neuropsychological testing have played a critical role in these advances. This study looks back at three major scientific advances in research on TBI that have been critical in pushing the field forward over the past several decades: The advent of modern neuroimaging; the recognition of the importance of non-injury factors in determining recovery from TBI; and the growth of cognitive rehabilitation. Thanks to these advances, we now have a better understanding of the pathophysiology of TBI and how recovery from the injury is also shaped by pre-injury, comorbid, and contextual factors, and we also have increasing evidence that active interventions, including cognitive rehabilitation, can help to promote better outcomes. The study also peers ahead to discern two important directions that seem destined to influence research on TBI over the next 50 years: the development of large, multi-site observational studies and randomized controlled trials, bolstered by international research consortia and the adoption of common data elements; and attempts to translate research into health care and health policy by the application of rigorous methods drawn from implementation science. Future research shaped by these trends should provide critical evidence regarding the outcomes of TBI and its treatment, and should help to disseminate and implement the knowledge gained from research to the betterment of the quality of life of persons with TBI.

    There is a dearth of systematic studies of expressive writing disorder (EWD) in persons with Traumatic Brain Injury (TBI). It is unclear if TBI survivors' written expression differs significantly from that experienced by persons with learning disabilities. It is also unclear which cognitive or neuropsychological variables predict problems with expressive writing (EW) or the EWD. This study investigated the EW skill, and the EWD in adults with mild traumatic brain injuries (TBI) relative to those with learning disabilities (LD). It also determined which of several cognitive variables predicted EW and EWD. Principle Component Analysis (PCA) of writing samples from 28 LD participants and 28 TBI survivors revealed four components of expressive writing skills: Reading Ease, Sentence Fluency, Grammar and Spelling, and Paragraph Fluency. There were no significant differences between the LD and TBI groups on any of the expressive writing components. Several neuropsychological variables predicted skills of written expression. The best predictors included measures of spatial perception, verbal IQ, working memory, and visual memory. TBI survivors and persons with LD do not differ markedly in terms of expressive writing skill. Measures of spatial perception, visual memory, verbal intelligence, and working memory predict writing skill in both groups. Several therapeutic interventions are suggested that are specifically designed to improve deficits in expressive writing skills in individuals with TBI and LD.

    Football players are more to violent impacts and injuries more than any athlete in any other sport. Concussion or mild traumatic brain injuries were one of the lesser known sports injuries until the last decade. With the advent of modern technologies in medical and engineering disciplines, people are now more aware of concussion detection and prevention. These concussions are often overlooked by football players themselves. The cumulative effect of these mild traumatic brain injuries can cause long-term residual brain dysfunctions. The principle of concussion is based the movement of the brain in the neurocranium and viscerocranium. The brain is encapsulated by the cerebrospinal fluid which acts as a protective layer for the brain. This fluid can protect the brain against minor movements, however, any rapid movements of the brain may mitigate the protective capability of the cerebrospinal fluid. In this paper, we propose a wireless health monitoring helmet that addresses the concerns of the current monitoring methods - it is non-invasive for a football player as helmet is not an additional gear, it is efficient in performance as it is equipped with EEG nanosensors and 3D accelerometer, it does not restrict the movement of the user as it wirelessly communicates to the remote monitoring station, requirement of individual monitoring stations are not required for each player as the ZigBee protocol can couple multiple transmitters with one receiver. A helmet was developed and validated according to the above mentioned parameters.

    Determine the extent that participation in Resource Mothers Program (RMP) home visiting improves maternal health at 3 months postpartum. A randomized controlled trial using RMPs in two urban and one rural location in a mid-Atlantic state. Community health workers from these RMPs enrolled teens into the study and the research team assigned participants to either the intervention group or telephone support control group using computerized randomization assignments. Data collection from baseline and 3 months postpartum using the Edinburgh Postnatal Depression Scale (EPDS) and the Prenatal Psychosocial Profile (PPP) is reported. The sample included 150 pregnant teens with a mean age of 17 years. Mean self-esteem scores between groups were not significantly different at baseline, but the RMP group self-esteem scores improved significantly at the 3 months postpartum interview (36.40 ± 5.63 for RMP vs. 34.10 ± 4.29 telephone control group, p = 0.049). Neither group was at risk for depression at baseline or 3 months postpartum. Because 60% of the total sample identified as Hispanic, post hoc analysis revealed significantly different baseline stress mean scores between Hispanic and non-Hispanic teens (p = 0.038); however, these differences were no longer significant by 3 months postpartum (p = 0.073). The EPDS scores by ethnicity were not different at baseline (p = 0.875) but were significantly different at 3 months (p = 0.007). The RMP home-visiting intervention can lead to improved self-esteem scores in teens, particularly in Hispanic teens. Improved self-esteem has been shown to lead to better parenting.

    Full Text Available There is a gap in knowledge about the mechanisms of sports-related brain injuries. The objective of this study was to determine the mechanisms of brain injuries among children and youth participating in team sports.We conducted a retrospective case series of brain injuries suffered by children participating in team sports. The Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP database was searched for brain injury cases among 5-19 year-olds playing ice hockey, soccer, American football (football, basketball, baseball, or rugby between 1990 and 2009. Mechanisms of injury were classified as "struck by player," "struck by object," "struck by sport implement," "struck surface," and "other." A descriptive analysis was performed.There were 12,799 brain injuries related to six team sports (16.2% of all brain injuries registered in CHIRPP. Males represented 81% of injuries and the mean age was 13.2 years. Ice hockey accounted for the greatest number of brain injuries (44.3%, followed by soccer (19.0% and football (12.9%. In ice hockey, rugby, and basketball, striking another player was the most common injury mechanism. Football, basketball, and soccer also demonstrated high proportions of injuries due to contact with an object (e.g., post among younger players. In baseball, a common mechanism in the 5-9 year-old group was being hit with a bat as a result of standing too close to the batter (26.1% males, 28.3% females.Many sports-related brain injury mechanisms are preventable. The results suggest that further efforts aimed at universal rule changes, safer playing environments, and the education of coaches, players, and parents should be targeted in maximizing prevention of sport-related brain injury using a multifaceted approach.

  2. Sociosexual and communication deficits after traumatic injury to the developing murine brain.

    Directory of Open Access Journals (Sweden)

    Bridgette D Semple

    Full Text Available Despite the life-long implications of social and communication dysfunction after pediatric traumatic brain injury, there is a poor understanding of these deficits in terms of their developmental trajectory and underlying mechanisms. In a well-characterized murine model of pediatric brain injury, we recently demonstrated that pronounced deficits in social interactions emerge across maturation to adulthood after injury at postnatal day (p 21, approximating a toddler-aged child. Extending these findings, we here hypothesized that these social deficits are dependent upon brain maturation at the time of injury, and coincide with abnormal sociosexual behaviors and communication. Age-dependent vulnerability of the developing brain to social deficits was addressed by comparing behavioral and neuroanatomical outcomes in mice injured at either a pediatric age (p21 or during adolescence (p35. Sociosexual behaviors including social investigation and mounting were evaluated in a resident-intruder paradigm at adulthood. These outcomes were complemented by assays of urine scent marking and ultrasonic vocalizations as indices of social communication. We provide evidence of sociosexual deficits after brain injury at p21, which manifest as reduced mounting behavior and scent marking towards an unfamiliar female at adulthood. In contrast, with the exception of the loss of social recognition in a three-chamber social approach task, mice that received TBI at adolescence were remarkably resilient to social deficits at adulthood. Increased emission of ultrasonic vocalizations (USVs as well as preferential emission of high frequency USVs after injury was dependent upon both the stimulus and prior social experience. Contrary to the hypothesis that changes in white matter volume may underlie social dysfunction, injury at both p21 and p35 resulted in a similar degree of atrophy of the corpus callosum by adulthood. However, loss of hippocampal tissue was greater after p21

    2011-09-01

    Full Text Available Abstract Background Perinatal brain injury is the leading cause of subsequent neurological disability in both term and preterm baby. Glutamate excitotoxicity is one of the major factors involved in perinatal hypoxic-ischemic encephalopathy (HIE. Glutamate transporter GLT1, expressed mainly in mature astrocytes, is the major glutamate transporter in the brain. HIE induced excessive glutamate release which is not reuptaked by immature astrocytes may induce neuronal damage. Compounds, such as ceftriaxone, that enhance the expression of GLT1 may exert neuroprotective effect in HIE. Methods We used a neonatal rat model of HIE by unilateral ligation of carotid artery and subsequent exposure to 8% oxygen for 2 hrs on postnatal day 7 (P7 rats. Neonatal rats were administered three dosages of an antibiotic, ceftriaxone, 48 hrs prior to experimental HIE. Neurobehavioral tests of treated rats were assessed. Brain sections from P14 rats were examined with Nissl and immunohistochemical stain, and TUNEL assay. GLT1 protein expression was evaluated by Western blot and immunohistochemistry. Results Pre-treatment with 200 mg/kg ceftriaxone significantly reduced the brain injury scores and apoptotic cells in the hippocampus, restored myelination in the external capsule of P14 rats, and improved the hypoxia-ischemia induced learning and memory deficit of P23-24 rats. GLT1 expression was observed in the cortical neurons of ceftriaxone treated rats. Conclusion These results suggest that pre-treatment of infants at risk for HIE with ceftriaxone may reduce subsequent brain injury.

    In the United States, one third of all deaths in teens are a result of motor vehicle crashes, accounting for 6,000 deaths annually. Injury Free Coalition for Kids-Worcester in collaboration with Worcester Juvenile Court has developed an interactive program for first-time teenaged driving offenders, Reality Intensive Driver Education (Teen RIDE). This full-day program at the trauma center provides a realistic exposure to the consequences of risky driving behaviors. This article examined the driving offense recidivism rates for Teen RIDE participants versus a comparison group (CG). The intervention group (IG) consists of teenagers between 13 years and 17 years who have been arrested for the first time for a serious driving offense and are sentenced by a Worcester Juvenile Court Judge or Magistrate to the Teen RIDE program. They are required to attend the program as a condition of probation, so attendance is mandatory. Each participant in the IG completed the program and was tracked for driving reoffenses for 6 months after completion of the course. The CG consists of also first-time driving offenders. The CG was matched with the IG with respect to age (13-17 years), sex, and offense type. Springfield, Massachusetts, serves as the site for recruitment of the CG, since it is demographically similar to Worcester but 60 mi away. Students in the CG had no exposure to this program. Each CG member was also tracked for 6 months after arrest. The recidivism rate for Teen RIDE participants 6 months after the course is 6% with 0% reoffending more than once. The CG has a recidivism rate of 56% 6 months after the arrest and 14% have more than one reoffense. The CG is 13.062 (4.296-39.713) times more likely to reoffend, and this is significant (p Teen RIDE program provides an impactful exposure of the consequences of risky driving behaviors to teenaged participants. In addition, Teen RIDE participants are significantly less likely to reoffend after completion of the course

    1996-01-01

    The chronological changes of blood-brain barrier disruption, and diffusion and absorption of edema fluid were investigated in rats with cold-induced brain injury (vasogenic edema) using magnetic resonance imaging. Contrast medium was administered intravenously at 3 and 24 hours after lesioning as a tracer of edema fluid. Serial T 1 -weighted multiple-slice images were obtained for 180 minutes after contrast administration. Disruption of the blood-brain barrier was more prominent at 24 hours after lesioning than at 3 hours. Contrast medium leaked from the periphery of the injury and gradually diffused to the center of the lesion. Contrast medium diffused into the corpus callosum and the ventricular system (cerebrospinal fluid). Disruption of the blood-brain barrier induced by cold injury was most prominent at the periphery of the vasogenic edema. Edema fluid subsequently extended into the center of the lesion and was also absorbed by the ventricular system. Magnetic resonance imaging is a useful method to assess the efficacy of therapy for vasogenic edema. (author)

  9. Isoflurane provides neuroprotection in neonatal hypoxic ischemic brain injury by suppressing apoptosis

    Directory of Open Access Journals (Sweden)

    Full Text Available Abstract Background and objectives: Isoflurane is halogenated volatile ether used for inhalational anesthesia. It is widely used in clinics as an inhalational anesthetic. Neonatal hypoxic ischemia injury ensues in the immature brain that results in delayed cell death via excitotoxicity and oxidative stress. Isoflurane has shown neuroprotective properties that make a beneficial basis of using isoflurane in both cell culture and animal models, including various models of brain injury. We aimed to determine the neuroprotective effect of isoflurane on hypoxic brain injury and elucidated the underlying mechanism. Methods: A hippocampal slice, in artificial cerebrospinal fluid with glucose and oxygen deprivation, was used as an in vitro model for brain hypoxia. The orthodromic population spike and hypoxic injury potential were recorded in the CA1 and CA3 regions. Amino acid neurotransmitters concentration in perfusion solution of hippocampal slices was measured. Results: Isoflurane treatment caused delayed elimination of population spike and improved the recovery of population spike; decreased frequency of hypoxic injury potential, postponed the onset of hypoxic injury potential and increased the duration of hypoxic injury potential. Isoflurane treatment also decreased the hypoxia-induced release of amino acid neurotransmitters such as aspartate, glutamate and glycine induced by hypoxia, but the levels of γ-aminobutyric acid were elevated. Morphological studies showed that isoflurane treatment attenuated edema of pyramid neurons in the CA1 region. It also reduced apoptosis as evident by lowered expression of caspase-3 and PARP genes. Conclusions: Isoflurane showed a neuro-protective effect on hippocampal neuron injury induced by hypoxia through suppression of apoptosis.

    To describe a comprehensive, multidisciplinary approach to teen mothers and their children that significantly reduces repeat pregnancies. Retrospective review of repeat teen pregnancy data. Young Parent Program (YPP) at a university-based health center. 1386 teen mothers between the ages of 11 and 19 who participated in the YPP for at least three years. Comprehensive Care: for both teen mother and her baby, including prenatal and postnatal care, preventive care, reproductive services, mental health, and acute care visits. Family counseling and similar services were also provided to siblings of the teen. CONTINUITY OF CARE: Patients are seen by the same staff and attending physicians on each visit. The treatment team includes physicians, nurses, social worker, nutritionist, and psychologist, all of whom are available to provide care at each visit. Flexible hours: Including evening clinic to allow teens to attend school or work during the day. Financial incentive: Patients with no insurance are given free contraceptives and a "no charge" clinic visit. Extensive contraceptive counseling is provided prior to start of contraceptive use and at every clinic visit. Routine telephone and/or mail reminders of appointments Rate of repeat teen pregnancy. Only 11(.79%) had repeat pregnancies. Older youth appeared more likely to repeat a pregnancy. Comprehensive intervention for teen mothers can be very successful in reducing repeat teen pregnancy in those teens who participate consistently in the program over a period of years.

    To investigate whether goal management training (GMT) expanded to include external cuing and an emotional regulation module is associated with improved emotional regulation, psychological functioning, and quality of life (QOL) after chronic acquired brain injury (ABI). Randomized controlled trial with blinded outcome assessment at baseline, posttraining, and 6-month follow-up. Outpatient. Persons with ABI and executive dysfunction (N=70; 64% traumatic brain injury; 52% men; mean age ± SD, 43±13y; mean time since injury ± SD, 8.1±9.4y). Eight sessions of GMT in groups, including a new module addressing emotional regulation, and external cuing. A psychoeducative control condition (Brain Health Workshop) was matched on amount of training, therapist contact, and homework. Emotional regulation was assessed with the Brain Injury Rehabilitation Trust Regulation of Emotions Questionnaire, the Emotional Control subscale and the Emotion Regulation factor (Behavior Rating Inventory of Executive Function-Adult Version), and the Positive and Negative Affect subscales from the Dysexecutive Questionnaire. Secondary outcome measures included psychological distress (Hopkins Symptom Checklist-25) and QOL (Quality of Life After Brain Injury Scale). Findings indicated beneficial effects of GMT on emotional regulation skills in everyday life and in QOL 6 months posttreatment. No intervention effects on measures of psychological distress were registered. GMT is a promising intervention for improving emotional regulation after ABI, even in the chronic phase. More research using objective measures of emotional regulation is needed to investigate the efficacy of this type of training. Copyright © 2016 American Congress of Rehabilitation Medicine.

    Given that the literature suggests there are various (and often contradictory) interpretations of holistic practice in brain injury rehabilitation and multiple complexities in its implementation (including complex setting, discipline, and client-base factors), this study aimed to examine the experiences of practitioners in their conceptualization and delivery of holistic practice in their respective settings. Nineteen health practitioners purposively sampled from an extensive Brain Injury Network in Queensland, Australia participated in individual interviews. A systematic text analysis process using Leximancer qualitative analysis program was undertaken, followed by manual thematic analysis to develop overarching themes. The findings from this study have identified several items for future inter-professional development that will not only benefit the practitioners working in brain injury rehabilitation settings, but the patients and their families as well.

    Traumatic brain injury (TBI) can cause widespread and prolonged brain degeneration. TBI can affect cognitive function and brain integrity for many years after injury, often with lasting effects in children, whose brains are still immature. Although TBI varies in how it affects different individuals, image analysis methods such as tensor-based morphometry (TBM) can reveal common areas of brain atrophy on magnetic resonance imaging (MRI), secondary effects of the initial injury, which will differ between subjects. Here we studied 36 pediatric moderate to severe TBI (msTBI) participants in the post-acute phase (1-6 months post-injury) and 18 msTBI participants who returned for their chronic assessment, along with well-matched controls at both time-points. Participants completed a battery of cognitive tests that we used to create a global cognitive performance score. Using TBM, we created three-dimensional (3D) maps of individual and group differences in regional brain volumes. At both the post-acute and chronic time-points, the greatest group differences were expansion of the lateral ventricles and reduction of the lingual gyrus in the TBI group. We found a number of smaller clusters of volume reduction in the cingulate gyrus, thalamus, and fusiform gyrus, and throughout the frontal, temporal, and parietal cortices. Additionally, we found extensive associations between our cognitive performance measure and regional brain volume. Our results indicate a pattern of atrophy still detectable 1-year post-injury, which may partially underlie the cognitive deficits frequently found in TBI.

    In this work, we examine the physics underlying wave propagation in the head to evaluate various ultrasonic transducers for use in a brian injury detection device. The results of measurements of the attenuation coefficient and phase velocity for ultrasonic propagation in samples of brain tissue and skull bone from sheep are presented. The material properties are then used to investigate the propagation of ultrasonic pressure fields in the head. The ultrasound fields for three different transducers are calculated for propagation in a simulated brain/skull model. The model is constructed using speed-of-sound and mass density values of the two tissue types. The impact of the attenuation on the ultrasound fields is then examined. Finally, the relevant points drawn from these discussions are summarized. We hope to minimize the confounding effects of the skull by using sub-MHz ultrasound while maintaining the necessary temporal and spatial resolution to successfully detect injury in the brain.

    Despite successful performance on some audiovisual emotion tasks, hypoactivity has been observed in frontal and temporal integration cortices in individuals with autism spectrum disorders (ASD). Little is understood about the neurofunctional network underlying this ability in individuals with ASD. Research suggests that there may be processing biases in individuals with ASD, based on their ability to obtain meaningful information from the face and/or the voice. This functional magnetic resonance imaging study examined brain activity in teens with ASD (n = 18) and typically developing controls (n = 16) during audiovisual and unimodal emotion processing. Teens with ASD had a significantly lower accuracy when matching an emotional face to an emotion label. However, no differences in accuracy were observed between groups when matching an emotional voice or face-voice pair to an emotion label. In both groups brain activity during audiovisual emotion matching differed significantly from activity during unimodal emotion matching. Between-group analyses of audiovisual processing revealed significantly greater activation in teens with ASD in a parietofrontal network believed to be implicated in attention, goal-directed behaviors, and semantic processing. In contrast, controls showed greater activity in frontal and temporal association cortices during this task. These results suggest that in the absence of engaging integrative emotional networks during audiovisual emotion matching, teens with ASD may have recruited the parietofrontal network as an alternate compensatory system.

    Trauma and the mechanical strain of high-energy activity predispose athletes to pelvic injuries. Magnetic resonance imaging remains the primary modality for diagnosing these conditions, but ultrasonography-guided interventions are important in the management of core muscle, hip, and other pelvic conditions. This article reviews ultrasonography-guided interventions for injuries at the core, including the pelvis and hips. It reviews common injuries, procedure optimization, medication preparation, clinical evidence behind injections, tenotomy, and platelet-rich plasma. These interventions are especially important in athletes, because ultrasonography-guided procedures are often undertaken early in the treatment process, paralleling conservative rehabilitation to facilitate a faster return to play.
