Abstract
PURPOSE To identify the experiences and needs of dependent children who have a parent with an acquired brain injury (ABI) using a systematic review and thematic synthesis. MATERIALS AND METHODS A systematic search of Medline, Embase, PsycINFO, CINAHL Plus, and Web of Science was conducted. The search included variants of: "children," "parents," "acquired brain injury," and "experiences" or "needs." Eligible articles reported on the experiences/needs of dependent children who have a parent with an ABI, from the child's perspective. Thematic analysis was used to identify themes. RESULTS A total of 4895 unique titles were assessed, and 9 studies met inclusion. Four themes were identified: (1) Sustained Emotional Toll (subthemes: (i) Initial Shock and Distress; (ii) Ongoing Loss and Grief; (iii) Present-Day Stress and Emotions), (2) Responsibilities Change and Children Help Out, (3) Using Coping Strategies (subtheme: Talking Can Help), and (4) Wanting Information about the Injury. CONCLUSION Themes highlighted significant disruption and challenges to children's wellbeing across development, with ongoing and considerable impacts many years after the parent's injury. The nature of the experiences shifted with time since the parent's injury. These children need ongoing support starting shortly after their parent's injury that is grounded in their particular experiences.IMPLICATIONS FOR REHABILITATIONWhen a parent has an acquired brain injury (ABI), dependent children and adolescents face emotional upheaval, significant stressors, increased responsibilities, and lack of information about their parent's injury that persist even many years after injury.The nature of these experiences and therefore their needs change based on the acute versus later stages of the parent's injury.Children often do not ask questions or tell others how they feel, which means that they need support that asks about, and listens and responds to their needs.Support for children needs to start soon after the parent's injury, be grounded in the lived experiences of this group, consider their parent's recovery stage, and be embedded as part of service provision rather than rely on children or families to make service contact.

Abstract
PURPOSE People with acquired neurological disability have the right to quality disability support, yet there is still limited user insights shaping disability services. This research aimed to develop a comprehensive understanding of quality support for adults with acquired neurological disability based on lived experiences. METHODS Using a constructivist grounded theory approach, this project engaged 12 adults with acquired neurological disability, 12 support workers, and 10 close others in individual interviews. Each perspective was analysed independently and subsequently merged to construct a holistic model of quality support grounded in lived experience. RESULTS The model of quality support encompasses interconnected themes spanning dyadic relationships, support worker competency, team dynamics, provider practices, and sector-wide considerations. Key elements include recognising the individual's expertise in their support needs, nurturing effective support relationships, fostering a capable support team, and upholding sector accountability. Authentic choice and personal agency emerged as paramount factors in achieving quality support. CONCLUSIONS The findings align with disability rights and individualised funding principles, emphasising the centrality of people with lived experience in shaping support services. The research underscores the need to prioritise authentic choice and individual empowerment, offering valuable insights for both practice and policy development in the disability support sector.

Abstract
Blood-based biomarkers were recently proposed as predictors of traumatic brain injury (TBI) outcomes. This would be a critical step forward since the majority of TBI events are mild and structural brain damage in this group may be missed by current brain imaging methods. We sought to determine the performance of early measurement of interleukin-10 (IL-10) to distinguish computed tomography (CT)-positive from negative patients with mild TBI. We designed a single-center prospective observational study, which enrolled consecutive patients classed with mild TBI according to Glasgow Coma Scale [GCS] scores and appearance of at least one clinical symptom. Serum IL-10 levels were measured <3 h post hospital admission. The performance of IL-10 levels in correctly classifying patients was evaluated. IL-10 levels were significantly higher in the group with positive CT scans (p < 0.001). With sensitivity set at 100%, the specificity of IL-10 was only 38.1%. However, the specificities of IL-10 for prediction of negative and positive cases increased to 59% and 49%, respectively, when both parameters were assessed within 90 min of admission. For mild TBI patients between 36 and 66 years, classification performance increased significantly at the 100% sensitivity level with a specificity of 93%. Our results suggest that IL-10 may be an easily accessible clinically useful diagnostic biomarker that can distinguish between mild TBI patients with and without structural brain damage with higher effectiveness when lower times of blood sampling are employed and patients are between 36 and 66 years of age.

Abstract
OBJECTIVE To examine a resource provision program for individuals living with moderate-to-severe traumatic brain injury (TBI), using a comparison of the resources provided across social differences of language, nativity, and neighborhood. SETTING The Rusk Rehabilitation TBI Model System (RRTBIMS) collects data longitudinally on individuals from their associated private and public hospitals, located in New York City. PARTICIPANTS A total of 143 individuals with TBI or their family members. DESIGN An observational study of relative frequency of resource provision across variables of language, nativity, and neighborhood, using related-samples nonparametric analyses via Cochran's Q test. MAIN MEASURES Variables examined were language, place of birth, residence classification as medically underserved area/population (MUA), and resource categories. RESULTS Results indicate that US-born persons with TBI and those living in medically underserved communities are provided more resources than those who are born outside the United States or reside in communities identified as adequately medically served. Language was not found to be a factor. CONCLUSION Lessons learned from this research support the development of this resource provision program, as well as guide future programs addressing the gaps in health information resources for groups negatively impacted by social determinants of health (SDoH). An approach with immigrant participants should take steps to elicit questions and requests, or offer resources explicitly. We recommend research looking at what interpreter strategies are most effective and research on SDoH in relation to the dynamic interaction of variables in the neighborhood setting.

Traumatic Brain Injury Induces Microglial and Caspase3 Activation in the Retina. Int J Mol Sci 2023; 24:ijms24054451.

Abstract
Traumatic brain injury (TBI) is among the main causes of sudden death after head trauma. These injuries can result in severe degeneration and neuronal cell death in the CNS, including the retina, which is a crucial part of the brain responsible for perceiving and transmitting visual information. The long-term effects of mild-repetitive TBI (rmTBI) are far less studied thus far, even though damage induced by repetitive injuries occurring in the brain is more common, especially amongst athletes. rmTBI can also have a detrimental effect on the retina and the pathophysiology of these injuries is likely to differ from severe TBI (sTBI) retinal injury. Here, we show how rmTBI and sTBI can differentially affect the retina. Our results indicate an increase in the number of activated microglial cells and Caspase3-positive cells in the retina in both traumatic models, suggesting a rise in the level of inflammation and cell death after TBI. The pattern of microglial activation appears distributed and widespread but differs amongst the various retinal layers. sTBI induced microglial activation in both the superficial and deep retinal layers. In contrast to sTBI, no significant change occurred following the repetitive mild injury in the superficial layer, only the deep layer (spanning from the inner nuclear layer to the outer plexiform layer) shows microglial activation. This difference suggests that alternate response mechanisms play a role in the case of the different TBI incidents. The Caspase3 activation pattern showed a uniform increase in both the superficial and deep layers of the retina. This suggests a different action in the course of the disease in sTBI and rmTBI models and points to the need for new diagnostic procedures. Our present results suggest that the retina might serve as such a model of head injuries since the retinal tissue reacts to both forms of TBI and is the most accessible part of the human brain.

Exercise for People with Acquired Brain Injury: An ICF Perspective. APPLIED SCIENCES-BASEL 2022. [DOI: 10.3390/app12083862] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 11/16/2022]
Abstract
Exercise is an important element in the process of recovery from an acquired brain injury (ABI). However, specific guidance for exercise prescription and interventions in this population are missed. The aim of this study was to establish the key parameters to design and implement exercise programs based on the International Classification of Functioning, Disability, and Health (ICF) domains. A panel of experts that consisted of 13 professionals from neuro-rehabilitation centers evaluated the key parameters of this original proposal. The Heinemann methodology was used for all qualitative analyses. Additionally, Cronbach’s alpha was applied to the statistical analyses. According to the results, Cronbach’s alpha (0.97) indicated excellent internal consistency, and the experts perceptions ratified the proposed criteria to develop exercise programs for people with ABI. The proposed key parameters for the development of exercise programs for people with ABI based in ICF domains (body functions, activity—participation and environmental factors) bring a new, solid, and innovative tool for methodological design of these programs in sub-acute and chronic rehabilitation settings.

Unmet Rehabilitation Needs after Traumatic Brain Injury across Europe: Results from the CENTER-TBI Study. J Clin Med 2021; 10:jcm10051035.

Abstract
This study aims to assess rehabilitation needs and provision of rehabilitation services for individuals with moderate-to-severe disability and investigate factors influencing the probability of receiving rehabilitation within six months after traumatic brain injury (TBI). Overall, the analyses included 1206 individuals enrolled in the CENTER-TBI study with severe-to-moderate disability. Impairments in five outcome domains (daily life activities, physical, cognition, speech/language, and psychological) and the use of respective rehabilitation services (occupational therapy, physiotherapy, cognitive and speech therapies, and psychological counselling) were recorded. Sociodemographic and injury-related factors were used to investigate the probability of receiving rehabilitation. Physiotherapy was the most frequently provided rehabilitation service, followed by speech and occupational therapy. Psychological counselling was the least frequently accessed service. The probability of receiving a rehabilitative intervention increased for individuals with greater brain injury severity (odds ratio (OR) 1.75, CI 95%: 1.27–2.42), physical (OR 1.92, CI 95%: 1.21–3.05) and cognitive problems (OR 4.00, CI 95%: 2.34–6.83) but decreased for individuals reporting psychological problems (OR 0.57, CI 95%: 1.21–3.05). The study results emphasize the need for more extensive prescription of rehabilitation services for individuals with disability. Moreover, targeted rehabilitation programs, which aim to improve outcomes, should specifically involve psychological services to meet the needs of individuals recovering from TBI.

Case management after acquired brain injury compared to care as usual: study protocol for a 2-year pragmatic randomized controlled superiority trial with two parallel groups. Trials 2020; 21:928.

Abstract
Background People with acquired brain injury may suffer from cognitive, emotional and behavioural changes in the long term. Continuity of care is often lacking, leading to a variety of unmet needs and hindering psychosocial functioning from the occurrence of brain injury up to years thereafter. Case management aims to prevent (escalation of) problems and to facilitate timely access to appropriate services. In other populations, case management has shown to improve psychosocial well-being. In this study, we aim to evaluate the feasibility of case management after acquired brain injury and its effectiveness and cost-effectiveness, compared to care as usual. Methods This is a pragmatic randomized controlled superiority trial with two parallel groups and repeated measures in adults with ABI and their family, taking place between November 2019 and December 2021 in three provinces in the Netherlands. Participants will be randomly allocated to either the case management group, receiving case management from hospital discharge up to 2 years thereafter, or the control group, receiving care as usual. Effectiveness will be evaluated every 6 months for 18–24 months by patient-reported psychosocial well-being (Hospital Anxiety and Depression Scale (HADS), Utrecht Scale for Evaluation of Rehabilitation-Participation (USER-P) restriction subscale and the Life Satisfaction Questionnaire (LiSat)), self-management (Patient Activation Measure (PAM)) and care needs (Longer-term Unmet Needs after Stroke (LUNS)). Family outcomes include self-efficacy (Carer Self-Efficacy Scale (CSES)), caregiver burden (Caregiver Strain Index (CSI)), psychosocial well-being (LiSat, HADS), family needs (Family Needs Questionnaire (FNQ)). Feasibility will be evaluated using qualitative methods, assessing fidelity, dose delivered, dose received, reach, recruitment and context. Cost-effectiveness will be determined by the EQ-5D-3L and service use. Discussion At the moment, there is no integrated health care service for people with acquired brain injury and their family members in the long term. If case management is shown to be feasible and (cost)-effective, it could bridge the gap between patients’ and families’ needs and the available services.

Abstract
OBJECTIVES To assess the relationship of acute complications, preexisting chronic diseases, and substance abuse with clinical and functional outcomes among adults 50 years and older with moderate-to-severe traumatic brain injury (TBI). DESIGN Prospective cohort study. PARTICIPANTS Adults 50 years and older with moderate-to-severe TBI (n = 2134). MEASURES Clusters of comorbid health conditions empirically derived from non-injury International Classification of Diseases, Ninth Revision codes, demographic/injury variables, and outcome (acute and rehabilitation length of stay [LOS], Functional Independence Measure efficiency, posttraumatic amnesia [PTA] duration, institutionalization, rehospitalization, and Glasgow Outcome Scale-Extended (GOS-E) at 1 year). RESULTS Individuals with greater acute hospital complication burden were more often middle-aged men, injured in motor vehicle accidents, and had longer LOS and PTA. These same individuals experienced higher rates of 1-year rehospitalization and greater odds of unfavorable GOS-E scores at 1 year. Those with greater chronic disease burden were more likely to be rehospitalized at 1 year. Individuals with more substance abuse burden were most often younger (eg, middle adulthood), black race, less educated, injured via motor vehicle accidents, and had an increased risk for institutionalization. CONCLUSION Preexisting health conditions and acute complications contribute to TBI outcomes. This work provides a foundation to explore effects of comorbidity prevention and management on TBI recovery in older adults.

Abstract
Previous studies examining life after traumatic brain injury (TBI) have taken a predominantly short-term and quantitative perspective, with generally narrow focus, and have not specifically investigated changes in experience over time post-injury to gain a uniquely long-term perspective. This study therefore aimed to qualitatively explore the broad long-term experience of living for 10 years or more with TBI. Thirty participants completed semi-structured interviews investigating the impact of TBI on various life domains, the rehabilitation experience and support received, and overall perspectives of the long-term journey after TBI. Results demonstrated that: (a) although some participants reported full recovery, several experienced persistent physical, cognitive and emotional problems that impacted their independence, employment and interpersonal relationships; (b) early rehabilitation was very helpful, but some participants experienced difficulties accessing ongoing services; (c) family and social support were important to recovery; (d) most participants drew upon inner strength to find positives in their experience. These findings have identified factors that facilitate and impede long-term recovery from TBI, which may inform better support and care for injured individuals over the years after injury to improve their quality of life.

How the enriched get richer? Experience-dependent modulation of microRNAs and the therapeutic effects of environmental enrichment. Pharmacol Biochem Behav 2020; 195:172940.

Abstract
Environmental enrichment and physical exercise have many well-established health benefits. Although these environmental manipulations are known to delay symptom onset and progression in a variety of neurological and psychiatric conditions, the mechanisms underlying these effects remain poorly understood. A notable candidate molecular mechanism is that of microRNA, a family of small noncoding RNAs that are important regulators of gene expression. Research investigating the many diverse roles of microRNAs has greatly expanded over the past decade, with several promising preclinical and clinical studies highlighting the role of dysregulated microRNA expression (in the brain, blood and other peripheral systems) in understanding the aetiology of disease. Altered microRNA levels have also been described following environmental interventions such as exercise and environmental enrichment in non-clinical populations and wild-type animals, as well as in some brain disorders and associated preclinical models. Recent studies exploring the effects of stimulating environments on microRNA levels in the brain have revealed an array of changes that are likely to have important downstream effects on gene expression, and thus may regulate a variety of cellular processes. Here we review literature that explores the differential expression of microRNAs in rodents following environmental enrichment and exercise, in both healthy control animals and preclinical models of relevance to neurological and psychiatric disorders.

Abstract
BACKGROUND Traumatic brain injury (TBI) is often associated with life-long medical, cognitive, emotional, and behavioral changes. Although long-lasting disabilities are expected, research on effective treatment options in the chronic phase of TBI is scarce. METHODS/DESIGN This study protocol describes a randomized controlled trial (RCT) aimed at evaluating the effectiveness of a goal-oriented and community-based intervention for increasing community integration, quality of life, and functional independence in the chronic phase of complicated mild to severe TBI. Participants will be recruited from Oslo University Hospital, Norway. Patients aged 18-72 years living at home with MRI/CT-verified intracranial abnormalities, a TBI diagnosis, a time since injury of ≥ 2 years, and who experience either current TBI-related problems or restrictions in community integration will be included. The 120 participants will be randomized 1:1 to either (a) an intervention group, which will receive an in-home intervention program over 4 months, or (b) a control group receiving standard care in the municipalities. The intervention will consist of six home visits and two telephone contacts with a rehabilitation professional. A SMART-goal approach will be adopted to target the individual's self-reported TBI difficulties in everyday life. Primary outcomes will be self-reported quality of life and participation. Secondary outcomes include symptom burden, emotional functioning, and clinician-assessed global outcome and need for rehabilitation services. Outcomes will be evaluated at baseline and 4-5 and 12 months after baseline. Caregiver burden and general health will be assessed in participating family members. Goal attainment and acceptability will be evaluated in the intervention group. A process evaluation will be carried out to evaluate protocol adherence, and a cost-effectiveness analysis will be applied if the intervention is found to be effective. DISCUSSION The current study provides an innovative approach to rehabilitation in the chronic phase of TBI evaluated using an RCT design that may inform treatment planning, health policies, and coordination of patient care. Further, the study may demonstrate new modes of establishing collaboration and knowledge transition between specialized rehabilitation facilities and local rehabilitation services that may improve patient outcomes.

Abstract
Objective: Although the long-term consequences of acquired brain injury are frequent and diverse, care and support over the longer term is an under-addressed issue. This study aims to identify the perceived needs of people with acquired brain injury and their partners.Methods: Interviews with four focus groups of people with brain injury (n = 17) and three partner groups (n = 19) were audio- and videotaped, transcribed verbatim and analyzed using inductive content analysis.Results: Needs were perceived on the intrapersonal, social, healthcare and societal levels, focusing on three themes: 1) Adaptation to changes, including awareness of consequences, acceptance, role changes and dealing with these; 2) Understanding from relatives/friends, professionals, institutions and society; 3) Timely, individualized care, involving information, transition to home, searching for support, peer support and support for partner/family.Discussion: The variety and complexity of needs show that people with brain injury and their partners need to find a new balance in order to live a fulfilling life despite the consequences of brain injury. The overarching need for continuity of care from the transition to home onwards provides important implications for supporting the process of learning how to live well with brain injury.

Abstract
Introduction: The Groningen Effort Test (GET) is a recently developed performance validity test (PVT) for the identification of noncredible performance in a neuropsychological assessment of attention abilities. Because the majority of already established PVTs are based on memory functions, the GET has the potential to make a valuable contribution to validity testing.Method: The current study examined the utility of the GET in the detection of feigned cognitive dysfunction after acquired brain injury (ABI) and its incremental validity over already established PVTs, namely the Test of Memory Malingering (TOMM), the Dot Counting Test (DCT), and the b Test. Three hundred and forty-eight participants took part in this study, including 58 patients with ABI (stroke or traumatic brain injury), 43 healthy individuals instructed to show normal behavior, and 247 healthy individuals instructed to feign cognitive dysfunction after ABI.Results: With excellent overall classification accuracy, the GET performed close to the level of the TOMM, and superior to the b Test and DCT. Data analyses further revealed that the GET provides additional diagnostic accuracy compared to the b Test and the DCT in the detection of feigned cognitive dysfunction, but has no incremental validity over the TOMM. For each of the four PVTs in this study, diagnostic sensitivity was independent of the simulation strategy used.Conclusions: It is concluded that the GET is an attention-based PVT with promising test characteristics and high diagnostic accuracy in the detection of noncredible cognitive performance using a simulation design. Given the results can be replicated in studies using known-groups methodology, it may be a useful tool for clinical practice to complement neuropsychological assessments of patients with ABI.

Abstract
Diffuse axonal injury (DAI) is a frequent injury after traumatic brain injury (TBI), which causes cognitive and behavioral symptoms. Behavioral changes after DAI affect the patients' quality of life, in addition to causing great damage to their family and society. This study aimed to analyze the behavioral changes of patients with DAI according to family members and to identify the associated factors. This study included patients with DAI, aged between 18 and 60 years, who presented to a referral hospital for traumatic injuries. A prospective cohort study was conducted with 2 evaluations of family members at 3, 6, and 12 months posttrauma. Behavioral changes were evaluated using a questionnaire designed to identify changes according to the perception of family members. The mixed-effects model was applied to identify significant behavioral changes, the effect of time on these changes, and the association between sociodemographic variables, DAI severity, and behavioral changes. Anxiety, dependency, depression, irritability, memory, and mood swings were significantly different (p ≤ .05) before and after trauma. An analysis of the evolution of these behaviors showed that the changes persisted with the same intensity up to 12 months posttrauma. There was an association between depression and income, age and irritability, and DAI severity and dependency. Unfavorable behavioral changes were frequent consequences of DAI, and no improvement in these changes was noted up to 12 months after the injury. Income, age, and DAI severity were related to behavioral changes.

Abstract
BACKGROUND Persons with moderate-to-severe traumatic brain injury (TBI) face issues with health, wellness, and safety that affect their ability to independently manage their care, even for individuals who are ≥75% independent in activities of daily living. These issues often lead to increased family involvement in managing the person's condition after discharge home. PURPOSE We explored health, wellness, and safety concerns after discharge home from inpatient rehabilitation from the perspectives of persons with TBI who are ≥75% independent in activities of daily living and their family caregivers. MATERIALS AND METHODS We interviewed 27 persons with TBI and family caregivers and used conventional content analysis to analyse the data. RESULTS Seven themes related to health, wellness, and safety encompassed participants' experience. Health themes included: (1) attempting to manage medications and (2) navigating mental health difficulties. Wellness themes included: (1) working to stay physically active, (2) dealing with sleep and sleeplessness, and (3) adjusting to changing social relationships. Safety themes were: (1) addressing mobility challenges and (2) compensating for complications with cognitive functioning. CONCLUSIONS Findings can guide the development of tools, supports, and resources to promote health, wellness, and safety of persons with TBI as they recover after discharge home.Implications for rehabilitationFindings on numerous concerns related to health, wellness, and safety suggest the need for implementation or development and testing of tools, supports, and resources to promote health, wellness, and safety of persons with traumatic brain injury as they recover after discharge home.Our findings can be used to educate healthcare providers and increase awareness of the nuanced challenges patients and families face after discharge home.Findings can also be used by providers to educate patients and families on realistic expectations for life after discharge.

Abstract
For most individuals with traumatic brain injury (TBI), the ability to work is crucial to financial and psychological well-being. TBI produces a wide range of cognitive, physical, emotional, and interpersonal impairments that may undermine the ability to work. Employment is therefore a primary goal of TBI rehabilitation and has been the focus of extensive research. Although this literature has identified predictors of employment outcomes, few studies have examined the mechanisms that underlie these associations. Mediation analysis can identify these mechanisms, provide a more nuanced view of how predictors jointly affect rehabilitation outcomes, and identify predictors that, if treatable conditions, could be useful targets for tertiary prevention. Such efforts are aimed at reducing long-term impairments, disability, or suffering resulting from the injury. The study sample comprised 83 U.S. military veterans with TBI who had participated in a larger rehabilitation study and were interviewed in their homes. Bivariate tests revealed significant associations of employment with pain, cognitive functioning, self-rated health, depressive symptoms and physical functioning; the latter variable was operationalized in two ways—using the Patient Competency Rating Scale and the SF–36V physical functioning subscales. Because these physical functioning measures were highly intercorrelated (r = 0.69, p < 0.0001), separate regression models were conducted. In the hierarchical binary logistic regression models, predictors were entered in order of modifiability, with comorbidities (pain) entered in block 1, physical health/functioning sequelae in block 2, and depressive symptoms in block 3. In the regression using the SF-36V measure of physical functioning, pain's effect was mediated by the physical functioning/health predictors, with only physical functioning emerging as significant, but this effect was itself mediated by depressive symptoms. In the regression using the PCRS physical-function measure, only depressive symptoms emerged as a mediator of other effects. Findings underscore the central role of depression in the employment status of veterans with TBI, suggesting that negative effects of other problems/limitations could be mitigated by more effective treatment of depression. Thus, for many with chronic TBI who live with vocational limitations, outcomes may improve with lower depression. Findings argue for the wider use of mediation approaches in TBI research as a means of identifying targets for tertiary prevention of poor outcomes.

Abstract
INTRODUCTION Traumatic brain injury (TBI) represents a major health and socioeconomic problem internationally. The expansive nature of injuries results in a heterogeneous population. The degree and type of long-term impacts following TBI and improvement following injury are highly variable. The use of electronic Patient Reported Outcomes Measures (ePROMs) could help identify residual impacts of TBI and support patient management and care. The Patient Reported Outcomes Research in Trauma study is a qualitative study exploring the long-term symptoms and impacts that are experienced by those with TBI and the potential utility of an ePROM platform to collect real-time information on patient symptoms and quality of life to inform treatment and identify support needs. METHODS AND ANALYSIS Semi-structured telephone and face-to-face interviews will be conducted with approximately 30-40 individuals recruited from five groups: (1) people with TBI; (2) carers and relatives of individuals with TBI; (3) TBI healthcare professionals; (4) researchers and (5) third sector staff members and volunteers working with those with TBI. Data will be analysed using directed thematic analysis employing an iterative coding frame that will be modified as analysis progresses. Intercoder triangulation will be employed to enhance credibility. ETHICS AND DISSEMINATION This study was approved by the West Midlands-Black Country Research Ethics Committee (Ref: 18/WM/0033). Findings will be disseminated via conference presentations, peer-reviewed journals, social media (@CPROR_UoB; http://www.birmingham.ac.uk/cpror) and the National Institute for Health Research Surgical Reconstruction and Microbiology Research Centre.

Abstract
TITLE Care coordination experiences of people with traumatic brain injury and their family members 4-years after injury: A qualitative analysis. AIM To explore experiences of care coordination in the first 4-years after severe traumatic brain injury (TBI). METHODS A qualitative study nested within a population-based longitudinal cohort study. Eighteen semi-structured telephone interviews were conducted 48-months post-injury with six adults living with severe TBI and the family members of 12 other adults living with severe TBI. Participants were identified through purposive sampling from the Victorian State Trauma Registry. A thematic analysis was undertaken. RESULTS No person with TBI or their family member reported a case manager or care coordinator were involved in assisting with all aspects of their care. Many people with severe TBI experienced ineffective care coordination resulting in difficulty accessing services, variable quality in the timing, efficiency and appropriateness of services, an absence of regular progress evaluations and collaboratively formulated long-term plans. Some family members attempted to fill gaps in care, often without success. In contrast, effective care coordination was reported by one family member who advocated for services, closely monitored their relative, and effectively facilitated communication between services providers. CONCLUSION Given the high cost, complexity and long-term nature of TBI recovery, more effective care coordination is required to consistently meet the needs of people with severe TBI.

Abstract
OBJECTIVE To provide a qualitative examination of the service and support needs of children who have had a mild traumatic brain injury (mTBI), and their parents, in order to improve clinical services. METHODS Semi-structured interviews were conducted with 9 children (8-12 years; M = 10.6 years, SD = 0.8) and their parents (n = 9) 29-55 days (M = 34 days; SD = 9.3) after presenting to an Australian Paediatric Emergency Department (PED) for mTBI. Children's post-concussive symptoms (PCS) were additionally measured using the Post-Concussive Symptom Inventory (PCSI). Audio recordings were transcribed, and a thematic analysis was conducted. RESULTS Post-injury needs were reflected in four main themes: Communication; Family Burden; Continuity of Care; and Social and Community Support. These themes reflected children's and parents' needs for information, emotional/social/community support, and follow-up care. Both the children's and parents' needs, and the extent to which they were met, appeared to be related to the severity and duration of the child's PCS. CONCLUSIONS Dedicated pediatric mTBI follow-up services that build on family's resources and meet their individual needs for information, emotional support, and referral may assist in optimizing post-injury outcomes.

[PMID: 29571711 DOI: 10.1016/j.taap.2018.03.020] [Citation(s) in RCA: 76] [Impact Index Per Article: 12.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2017] [Revised: 03/15/2018] [Accepted: 03/19/2018] [Indexed: 12/28/2022]
Abstract
Traumatic brain injury (TBI), which leads to high mortality and morbidity, is a prominent public health problem worldwide with no effective treatment. Curcumin has been shown to be beneficial for neuroprotection in vivo and in vitro, but the underlying mechanism remains unclear. This study determined whether the neuroprotective role of curcumin in mouse TBI is dependent on the NF-E2-related factor (Nrf2) pathway. The Feeney weight-drop contusion model was used to mimic TBI. Curcumin was administered intraperitoneally 15 min after TBI induction, and brains were collected at 24 h after TBI. The levels of Nrf2 and its downstream genes (Hmox-1, Nqo1, Gclm, and Gclc) were detected by Western blot and qRT-PCR at 24 h after TBI. In addition, edema, oxidative damage, cell apoptosis and inflammatory reactions were evaluated in wild type (WT) and Nrf2-knockout (Nrf2-KO) mice to explore the role of Nrf2 signaling after curcumin treatment. In wild type mice, curcumin treatment resulted in reduced ipsilateral cortex injury, neutrophil infiltration, and microglia activation, improving neuron survival against TBI-induced apoptosis and degeneration. These effects were accompanied by increased expression and nuclear translocation of Nrf2, and enhanced expression of antioxidant enzymes. However, Nrf2 deletion attenuated the neuroprotective effects of curcumin in Nrf2-KO mice after TBI. These findings demonstrated that curcumin effects on TBI are associated with the activation the Nrf2 pathway, providing novel insights into the neuroprotective role of Nrf2 and the potential therapeutic use of curcumin for TBI.

Abstract
BACKGROUND Patients with acquired brain injury (ABI) and their families have unique experiences and needs during the hospital stay; yet, limited literature exists on this topic. The purpose of this systematic review was to compile and synthesize literature on the experience of patients with ABI and their families during the hospital stay. METHODS A systematic review of qualitative studies was conducted by searching for studies from seven databases. Content analysis was used to analyse and synthesize studies' findings separately for the patient and family experience. RESULTS The initial search provided 2871 records. Ultimately, 11 studies relevant to the research question were included in this review. No studies were excluded based on critical quality appraisal. Findings on the patient experience showed patients had negative perceptions of the rehabilitation environment and a perceived need for information. Findings on the family experience included difficulty adjusting after the patient's injury, a desire to be involved in the patient's care, mixed feelings about staff support and a high perceived need for information. CONCLUSIONS Findings provide awareness for healthcare providers on the multifaceted experiences of patients with ABI and their families during the hospital stay, strategies to make care more patient- and family-centred and directions for future research.

Abstract
INTRODUCTION The Forced-choice Graphics Memory Test (FGMT) is a newly developed measure to assess feigned cognitive impairment. This study investigated the ability and reliability of FGMT for identification of malingering in patients with traumatic brain injury (TBI). METHODS The FGMT was administered to 40 healthy volunteers instructed to respond validly (Healthy Control, H-C), 40 healthy volunteers instructed to feign cognitive impairment (Healthy Malingering, H-M), 40 severe TBI patients who responded validly (TBI control, TBI-C), and 30 severe TBI patients who evidenced invalid performance (TBI malingering, TBI-M). RESULTS Both malingering groups (H-M and TBI-M) performed much more poorly than the nonmalingering groups (H-C and TBI-C). The FGMT overall total score, score on easy items, and score on hard items differed significantly across the four groups. The total score showed the highest classification accuracy in differentiating malingering from nonmalingering. A cutoff of less than 18 (total items) successfully identified 95% of TBI-C and 93.3% of TBI-M participants. The FGMT also demonstrated high test-retest reliability and internal consistency. FGMT scores were not affected by TBI patients' education, gender, age, or intelligence. CONCLUSION Our results suggest that the FGMT can be used as a fast and reliable tool for identification of feigned cognitive impairment in patients with TBI.

Abstract
OBJECTIVE To identify factors that people with a traumatic brain injury and their families perceived as helping to improve their quality of life. METHODS Three focus groups and five interviews were conducted with a total of 37 participants: 14 persons with traumatic brain injury and 23 caregivers. A content analysis was conducted. The constant comparative method was applied. RESULTS We detected five factors that improved the quality of life of persons with a traumatic brain and their families: 1) Informal support (family and friends); 2) formal support (counseling, employment, built and bureaucratic environment); 3) type of clinical characteristics; 4) social participation, and 5) social visibility. CONCLUSIONS The needs expressed by our participants primarily focused on social and emotional factors. For persons with severe traumatic brain injury attempting to achieve the best possible community integration, a new semiology is required, not limited to medical care, but also involving social and psychological care tailored to the needs of each individual and family and their environment.

Abstract
OBJECTIVES Injury is a major public health problem. While the impacts of injury on the injured person are well documented, there is relatively little knowledge about the impacts of injury on those individuals and groups in the community connected to the injured person. This study seeks to describe this breadth of research using a meta-review methodology. STUDY DESIGN Systematic meta-review. METHODS To gain a better understanding of the known impacts of injury on family, community and society, a systematic meta-review of injury outcomes research literature was conducted. Seventy-eight peer-reviewed published literature reviews were included in the meta-review. RESULTS Of these, 70 reported outcomes at the level of the injured person including mortality, body functions, activity and participation limitations. Nine reviews reported impacts at the level of the community including impacts on family members, work colleagues and carers. Six studies reported impacts at the societal level including economic, health system and injury compensation system impacts. CONCLUSIONS In summary, the meta-review identified a substantial body of knowledge at the individual level outcomes of injury, and a relative lack of information regarding the community and societal impacts of injury. An injury outcome framework is proposed on the basis of the findings of the meta-review to guide future research activity, particularly with regard to injury outcome domains where there is currently limited evidence. A comprehensive framework that takes account of all levels of impact is necessary for effective policies, systems and strategies to support recovery following injury.

Abstract
The changes of microRNA expression in rat hippocampus after traumatic brain injury (TBI) were explored. Adult SD rats received a single controlled cortical impact injury, and the ipsilateral hippocampus was harvested for the subsequent microarray assay at three time points after TBI: 1st day, 3rd day and 5th day, respectively. We characterized the microRNA expression profile in rat hippocampus using the microRNA microarray analysis, and further verified microarray results of miR-142-3p and miR-221 using quantitative real-time PCR. Totally 205 microRNAs were identified and up-/down-regulated more than 1.5 times. There were significant changes in 17 microRNAs at all three time points post-TBI. The quantitative real-time PCR results of miR-142-3p and miR-221 indicated good consistency with the results of the microarray method. MicroRNAs altered at different time points post-TBI. MiR-142-3p and miR-221 may be used as potentially biological markers for TBI assessment in forensic practice.

Abstract
Traumatic brain injury (TBI) is a common cause for cognitive and communication problems, but the molecular and cellular mechanisms are not well understood. Epigenetic modifications, such as microRNA (miRNA) dysregulation, may underlie altered gene expression in the brain, especially hippocampus that plays a major role in spatial learning and memory and is vulnerable to TBI. To advance our understanding of miRNA in pathophysiological processes of TBI, we carried out a time-course microarray analysis of microRNA expression profile in rat ipsilateral hippocampus and examined histological changes, apoptosis and synapse ultrastructure of hippocampus post moderate TBI. We found that 10 out of 156 reliably detected miRNAs were significantly and consistently altered from one hour to seven days after injury. Bioinformatic and gene ontology analyses revealed 107 putative target genes, as well as several biological processes that might be initiated by those dysregulated miRNAs. Among those differentially expressed microRNAs, miR-144, miR-153 and miR-340-5p were confirmed to be elevated at all five time points after TBI by quantitative RT-PCR. Western blots showed three of the predicated target proteins, calcium/calmodulin-dependent serine protein kinase (CASK), nuclear factor erythroid 2-related factor 2 (NRF2) and alpha-synuclein (SNCA), were concurrently down- regulated, suggesting that miR-144, miR-153 and miR-340-5p may play important roles collaboratively in the pathogenesis of TBI-induced cognitive and memory impairments. These microRNAs might serve as potential targets for progress assessment and intervention against TBI to mitigate secondary damage to the brain.

Abstract
OBJECTIVE To describe the self-perceived health care needs of patients with moderate-to-severe traumatic brain injury (TBI) and to assess the impact of the functional level at 1 year after injury on patients' unmet needs at the 5-year follow-up. DESIGN A prospective follow-up study. SETTING Clinical research. PARTICIPANTS A total of 93 patients participated in the 5-year follow-up. METHODS We registered demographic and injury-related data at the time of admission and the scores for the Disability Rating Scale, Glasgow Outcome Scale-Extended, and Short Form 36 subscales for physical functioning and mental health at 1 and 5 years. The patients' self-perceived health care needs and use of health care services at 5 years were the main outcome measurements. RESULTS At the 5-year follow-up, 70% of patients reported at least 1 perceived need. The self-perceived health care needs were met for 39% of the patients. The patients with unmet needs (n = 29 [31%]) reported frequent needs in emotional (65%), vocational (62%), and cognitive (58%) domains. These patients were significantly more likely to present a less severe disability on the Disability Rating Scale at the 1-year follow-up (odds ratio [OR] 0.11 [95% confidence interval {CI}, 0.02-0.7]; P = .02). Worse mental health at the 1-year follow-up and a younger age (16-29 years) largely predicted unmet needs at the 5-year follow-up (OR 3.28 [95% CI, 1.1-10.04], P = .04; and OR 4.93 [95% CI, 0.16-15.2], P = .005, respectively). CONCLUSION Gaps between self-perceived health care needs and health care services received at the 5-year follow-up were found. An important message to clinicians who provide health care services in the late TBI phase is that they should be aware of patients' long-term needs regarding cognitive and emotional difficulties. Of equal importance is an emphasis on long-term vocational rehabilitation services. To ensure the appropriateness of health care service delivery, health care services after TBI should be better targeted at less-severe TBI population as well.

Abstract
Patient outcomes are variable following severe traumatic brain injury (TBI); however, the biological underpinnings explaining this variability are unclear. Mitochondrial dysfunction after TBI is well documented, particularly in animal studies. The aim of this study was to investigate the role of mitochondrial polymorphisms on mitochondrial function and patient outcomes out to 1 year after a severe TBI in a human adult population. The Human MitoChip V2.0 was used to evaluate mitochondrial variants in an initial set of n=136 subjects. SNPs found to be significantly associated with patient outcomes [Glasgow Outcome Scale (GOS), Neurobehavioral Rating Scale (NRS), Disability Rating Scale (DRS), in-hospital mortality, and hospital length of stay] or neurochemical level (lactate:pyruvate ratio from cerebrospinal fluid) were further evaluated in an expanded sample of n=336 subjects. A10398G was associated with DRS at 6 and 12 months (p=0.02) and a significant time by SNP interaction for DRS was found (p=0.0013). The A10398 allele was associated with greater disability over time. There was a T195C by sex interaction for GOS (p=0.03) with the T195 allele associated with poorer outcomes in females. This is consistent with our findings that the T195 allele was associated with mitochondrial dysfunction (p=0.01), but only in females. This is the first study associating mitochondrial DNA variation with both mitochondrial function and neurobehavioral outcomes after TBI in humans. Our findings indicate that mitochondrial DNA variation may impact patient outcomes after a TBI potentially by influencing mitochondrial function, and that sex of the patient may be important in evaluating these associations in future studies.

Abstract
This study investigated the rehabilitation and services needs, rehabilitation goals and barriers of individuals with brain injury (n = 81, males = 59%, females = 41%, age range 18 to 87), and their family members (n = 19; females = 75%, age range 18 to 65), (ethnicity = white = 89%). Data were collected using a survey instrument and focus group interviews. A descriptive analysis of the quantitative data was conducted, while content analysis was used to analyse the qualitative data. Results suggest that individuals with brain injury and their families experience many unmet needs across the domains of employment, independent living, financial resources and housing. Family involvement was found to be important to community participation after brain injury.

Abstract
Traumatic brain injury (TBI) is a major cause of preventable death and morbidity in young adults. This complex condition is characterized by a significant blood-brain barrier leakage that stems from cerebral ischemia, inflammation, and redox imbalances in the traumatic penumbra of the injured brain. Recovery of function after TBI is partly through neuronal plasticity. In order to test whether combination therapy with melatonin and dexamethasone (DEX) might improve functional recovery, a controlled cortical impact (CCI) was performed in adult mice, acting as a model of TBI. Once trauma has occurred, combating these exacerbations is the keystone of an effective TBI therapy. The therapy with melatonin (10 mg/kg) and DEX (0.025 mg/kg) is able to reduce edema and brain infractions as evidenced by decreased 2,3,5-triphenyltetrazolium chloride staining across the brain sections. Melatonin- and DEX-mediated improvements in tissue histology shown by the reduction in lesion size and an improvement in apoptosis level further support the efficacy of combination therapy. The combination therapy also blocked the infiltration of astrocytes and reduced CCI-mediated oxidative stress. In addition, we have also clearly demonstrated that the combination therapy significantly ameliorated neurological scores. Taken together, our results clearly indicate that combination therapy with melatonin and DEX presents beneficial synergistic effects, and we consider it an avenue for further development of novel combination therapeutic agents in the treatment of TBI that are more effective than a single effector molecule.

Abstract
Traumatic brain injury (TBI) is a leading cause of injury-related death and disability worldwide. Effective treatment for TBI is limited and many TBI patients suffer from neuropsychiatric sequelae. The molecular and cellular mechanisms underlying the neuronal damage and impairment of mental abilities following TBI are largely unknown. Here we used the next generation sequencing platform to delineate miRNA transcriptome changes in the hippocampus at 24 hours and 7 days following TBI in the rat controlled cortical impact injury (CCI) model, and developed a bioinformatic analysis to identify cellular activities that are regulated by miRNAs differentially expressed in the CCI brains. The results of our study indicate that distinct sets of miRNAs are regulated at different post-traumatic times, and suggest that multiple miRNA species cooperatively regulate cellular pathways for the pathological changes and management of brain injury. The distinctive miRNAs expression profiles at different post-CCI times may be used as molecular signatures to assess TBI progression. In addition to known pathophysiological changes, our study identifies many other cellular pathways that are subjected to modification by differentially expressed miRNAs in TBI brains. These pathways can potentially be targeted for development of novel TBI treatment.

Abstract
PURPOSE This study examined the prediction of performance on measures of the Story Goodness Index (SGI; Lê, Coelho, Mozeiko, & Grafman, 2011) from executive function (EF) and memory measures following traumatic brain injury (TBI). It was hypothesized that EF and memory measures would significantly predict SGI outcomes. METHOD One hundred sixty-seven individuals with TBI participated in the study. Story retellings were analyzed using the SGI protocol. Three cognitive measures--Delis-Kaplan Executive Function System (D-KEFS; Delis, Kaplan, & Kramer, 2001) Sorting Test, Wechsler Memory Scale--Third Edition (WMS-III; Wechsler, 1997) Working Memory Primary Index (WMI), and WMS-III Immediate Memory Primary Index (IMI)--were entered into a multiple linear regression model for each discourse measure. Two sets of regression analyses were performed, the first with the Sorting Test as the first predictor and the second with it as the last. RESULTS The first set of regression analyses identified the Sorting Test and IMI as the only significant predictors of performance on measures of the SGI. The second set identified all measures as significant predictors when evaluating each step of the regression function. CONCLUSION The cognitive variables predicted performance on the SGI measures, although there were differences in the amount of explained variance. The results (a) suggest that storytelling ability draws on a number of underlying skills and (b) underscore the importance of using discrete cognitive tasks rather than broad cognitive indices to investigate the cognitive substrates of discourse.
