Abstract
BACKGROUND The evaluation of impaired self-awareness (ISA) after brain injury is not widespread in Japan, and there is a lack of Japanese assessments of self-awareness. OBJECTIVES To translate the original version of the Awareness Questionnaire (AQ), an instrument for assessing ISA, into Japanese using a validated method and examine its reliability and validity in inpatients with stroke. METHODS This cross-sectional, prospective study enrolled 130 participants. The double-translation process was used to develop the Japanese version of the AQ. RESULTS Data were collected from 120 patients. High intra-rater reliability was observed for the patient (Cronbach's α = 0.824) and clinician samples (Cronbach's α = 0.933). High intra- and inter-rater reliability were found for all AQ items [interclass coefficient (ICC) (1, 1) = 0.828, ICC (2, 1) = 0.852, ICC (3, 1) = 0.848]; however, the sub-item analysis revealed only moderate reliability. Validity assessment revealed a low but significant positive correlation (r = 0.209; p < 0.05) between the Japanese version of the AQ and the Japanese version of the Self-Regulation Skills Interview and a low but significant negative correlation (r = 0.197; p < 0.05) between the Japanese version of the AQ and the Mini-Mental State Examination. CONCLUSIONS The Japanese version of the AQ was developed and applied to stroke patients, but the concept of post-stroke ISA may differ from ISA after traumatic brain injury, highlighting the need for a stroke-specific version of the AQ.

Abstract
PURPOSE This study aimed to examine how moderate-to-vigorous physical activity (MVPA) during concussion recovery influences self-reported anxiety symptoms at follow-up assessment. We hypothesized that more MVPA after concussion would be associated with lower anxiety rating at follow-up. METHODS We performed a prospective study of participants aged 13-18 yr initially assessed within 14 d of diagnosed concussion. Participants rated concussion symptoms using the Post-Concussion Symptom Inventory and were provided a wrist-worn actigraphy device to track activity for 1 wk after assessment. At follow-up assessment, participants rated anxiety symptoms using the four-question Patient-Reported Outcomes Measurement Information System (PROMIS) anxiety subscale. Each question ranged from 1 (never) to 5 (almost always), with an overall score range of 4-20. For univariable analysis, we calculated correlation coefficients between MVPA and PROMIS anxiety subscale scores. We then created a multiple linear regression model with follow-up PROMIS anxiety subscale score as the outcome and MVPA, sex, initial symptom severity, and preconcussion anxiety as predictors. RESULTS We enrolled and initially tested 55 participants, and 48 were included in the final analysis (age, 14.6±2.7 yr; 56% female; initial assessment, 7.3± 3.1 d; follow-up assessment, 42.0±29.7 d). We observed an inverse and low correlation between MVPA and follow-up PROMIS anxiety subscale T-scores ( r = -0.30, P = 0.04). Multivariable regression results indicated that MVPA ( β = -5.30; 95% confidence interval (CI), -10.58 to -0.01), initial Post-Concussion Symptom Inventory score ( β = 0.11; 95% CI, 0.03 to 0.19), and preconcussion anxiety ( β = 5.56; 95% CI, 0.12 to 11.0), but not sex ( β = -2.60; 95% CI, -7.14, to 1.94), were associated with follow-up PROMIS anxiety subscale T-scores. CONCLUSIONS After adjusting for covariates, more MVPA early after concussion predicted lower PROMIS anxiety subscale scores at follow-up. Although initial concussion symptom severity and preconcussion anxiety were also associated with follow-up PROMIS anxiety subscale score, MVPA represents a modifiable factor that may contribute to lower anxiety symptoms.

Abstract
PURPOSE Concussion management is shifting away from a rest-is-best approach, as data now suggest that exercise-is-medicine for this mild brain injury. Despite this, we have limited data on habitual physical activity following concussion. Therefore, our objective was to quantify accelerometer-measured physical activity and sedentary time in children with concussion (within the first month of injury) and healthy controls. We hypothesized that children with concussion would be less active than their healthy peers. METHODS We performed a secondary analysis of prospectively collected accelerometer data. Our sample included children with concussion (n = 60, 31 females) and historical controls (n = 60) matched for age, sex, and season of accelerometer wear. RESULTS Children with concussion were significantly more sedentary than controls (mean difference [MD], 38.3 min/d, P = .006), and spent less time performing light physical activity (MD, -19.5 min/d, P = .008), moderate physical activity (MD, -9.8 min/d, P < .001), and vigorous physical activity (MD, -12.0 min/d, P < .001); these differences were observed from 8:00 AM to 9:00 PM. Sex-specific analyses identified that girls with concussion were less active and more sedentary than both boys with concussion (P = .010) and healthy girls (P < .010). CONCLUSION There is an activity deficit observed within the first month of pediatric concussion. Physical activity guidelines should address this while considering sex effects.

Abstract
OBJECTIVE To detect the expression levels of LINC02446 and S100B in serum of patients with traumatic brain injury (TBI) and explore their values as diagnostic and prognostic indicators for TBI. METHOD Abnormal expressed RNAs in brain injury were screened from the dataset GSE1131475. Serums were collected from moderate to severe TBI patients at 1-3 and 4-12 h post injury. Quantitative polymerase chain reaction was used to detect the expression levels of LINC02446 and S100B in serum. The Glasgow Outcome Scale was used for prognostic evaluation. The diagnostic and prognostic efficacy of LINC02446 and S100B in TBI was evaluated using the receiver operating characteristic (ROC) curve. RESULT The serum expression levels of LINC02446 and S100B in the TBI group were significantly increased. The expression levels of LINC02446 and S100B in the severe TBI group were significantly higher than those in the mild TBI group. ROC curve analysis showed that the combination of LINC02446 and S100B can distinguish TBI patients from healthy controls, as well as mild TBI from moderate to severe TBI. At the 6-month follow-up, the expression levels of LINC02446 and S100B in TBI patients with poor prognosis were significantly higher than those in patients with good prognosis, and ROC results showed their differentiation value. Moreover, the expression level of LINC02446 at 0-3 h can serve as an independent prognostic factor for poor prognosis. CONCLUSION Serum LINC02446 and S100B hold clinical application value in the diagnosis and prognosis of TBI and are expected to become new potential biomarkers.

Abstract
Oxidative stress (OS) and inflammation play a key role in the development of hypoxic-ischemic (H-I) induced brain damage. Following H-I, rapid neuronal death occurs during the acute phase of inflammation, and activation of the oxidant-antioxidant system contributes to the brain damage by activated microglia. So far, in an animal model of perinatal H-I, it was showed that neuroprostanes are present in all brain damaged areas, including the cerebral cortex, hippocampus and striatum. Based on the interplay between inflammation and OS, it was demonstrated in the same model that inflammation reduced brain sirtuin-1 expression and affected the expression of specific miRNAs. Moreover, through proteomic approach, an increased expression of genes and proteins in cerebral cortex synaptosomes has been revealed after induction of neonatal H-I. Administration of melatonin in the experimental treatment of brain damage and neurodegenerative diseases has produced promising therapeutic results. Melatonin protects against OS, contributes to reduce the generation of pro-inflammatory factors and promotes tissue regeneration and repair. Starting from the above cited aspects, this educational review aims to discuss the inflammatory and OS main pathways in H-I brain injury, focusing on the role of melatonin as neuroprotectant and providing current and emerging evidence.

Abstract
Some patients with heatstroke also experience intracerebral hemorrhage (ICH). However, clinical case reports of heatstroke-induced ICH are rare. The risk factors for cerebral hemorrhage after heatstroke remain unknown. The present study evaluated the clinical characteristics and risk factors of patients with heatstroke-related ICH. In this retrospective observational study, we collected data on all ICHs after heatstroke occurred between 2012 and 2022. The characteristics of patients with heatstroke-induced ICH were described. The risk factors for cerebral hemorrhage after heatstroke were examined using logistic regression analysis. In total, 177 patients were included in this study, and 11 patients with ICH secondary to heatstroke were identified. Variables with P values of <.05 in univariate models, comparing the cerebral hemorrhage and control groups, included heatstroke cause, temperature, heart rate, respiratory rate, vasopressor use, mechanical ventilation use, Acute Physiology and Chronic Health Evaluation II, total bilirubin, creatinine, platelet count, prothrombin time, procalcitonin, creatine kinase, disseminated intravascular coagulation (DIC) occurrence, and DIC score. Multivariate logistic regression showed that heatstroke patients with higher DIC scores (odds ratio, 18.402, 95% confidence interval, 1.384-244.763, P = .027) and higher creatine kinase levels (odds ratio, 1.021, 95% confidence interval, 1.002-1.041, P = .033) were at a higher risk of developing ICH. The death rate was higher in the cerebral hemorrhage group than in the control group (P = .042). Heatstroke-related cerebral hemorrhage may be associated with elevated creatinine levels and DIC severity (International Society on Thrombosis and Hemostasis score) after heatstroke, and heatstroke with cerebral hemorrhage may accelerate death.

Abstract
BACKGROUND Self-awareness impairment is common following acquired brain injury and can impact rehabilitation outcomes. Knowledge of factors associated with impaired self-awareness may assist with rehabilitation planning. OBJECTIVES To identify factors associated with self-awareness and determine predictors of self-awareness impairment for adults with traumatic brain injury (TBI) and stroke. DESIGN AND METHODS A retrospective cohort study of rehabilitation inpatients was conducted by medical record audit. Self-awareness was measured using the Self-awareness of Deficits Interview (SADI). Relationships between SADI scores and demographic and clinical variables were identified with non-parametric statistics. Predictors of SADI scores were identified using ordinal regression analyses for TBI and stroke groups. RESULTS Participants were 149 adults (18-70 years) with TBI (n = 110) and stroke (n = 39). For TBI, longer post-traumatic amnesia (PTA), lower functional cognition/communication, and behaviors of concern (BoC) were significantly associated with higher SADI scores (i.e. impaired self-awareness). For stroke, lower functional cognition/communication and motor scores were associated with higher SADI scores. Impaired self-awareness was predicted by PTA duration, acute length of stay and presence of BoC for the TBI group, and by functional cognition/communication for the stroke group. CONCLUSION Different factors were associated with impaired self-awareness for individuals with TBI and stroke during inpatient rehabilitation.

Abstract
INTRODUCTION The aim of the present study was to evaluate the characteristics of brain injury and to assess the relationship between them and treatment outcomes in patients with traumatic benign paroxysmal positional vertigo (t-BPPV). MATERIALS AND METHODS Sixty-three consecutive patients who were diagnosed with BPPV within 2 weeks after head trauma were included. RESULTS Cerebral concussion, intracranial hemorrhages (ICH), skull fracture without ICH, and hemorrhagic contusion were observed in 68%, 24%, 5%, and 3% of t-BPPV patients, respectively. BPPV with single canal involvement was observed in 52 (83%) patients and that with multiple canal involvement was observed in 11 (17%) patients. The number of treatment sessions was not significantly different according to the cause of head trauma (p = 0.252), type of brain injury (p = 0.308) or location of head trauma (p = 0.287). The number of recurrences was not significantly different according to the cause of head trauma (p = 0.308), type of brain injury (p = 0.536) or location of head trauma (p = 0.138). CONCLUSION The present study demonstrated that there were no significant differences in treatment sessions until resolution and the mean number of recurrences according to the type of brain injury.

Abstract
Pediatric traumatic brain injury (pTBI) is a major risk factor associated with adulthood incarceration. Most research into the link between pTBI and adulthood incarceration has focused on incarcerated males, who comprise the vast majority of incarcerated adults, particularly in industrialized nations. In this review, we sought to identify sex-related differences in the incidence and pathophysiology of pTBI and subsequent risk of adulthood incarceration. A scoping review was undertaken using PubMed, Scopus, Ovid, and the Cochrane Library. Articles analyzing sex-related differences in pTBI and adult incarceration rates, studies conducted on an incarcerated population, and cohort studies, cross-sectional studies, clinical trials, systematic reviews, or meta-analyses were included in this review. Of the 85 unique results, 25 articles met our inclusion criteria. Male children are 1.5 times more likely to suffer a TBI than females; however, the prevalence of incarcerated adults with a history of pTBI is ∼35-45% for both sexes. Neurophysiologically, female sex hormones are implicated in neuroprotective roles, mitigating central nervous system (CNS) damage post-TBI, although this role may be more complex, given that injury severity and sequelae have been correlated with male sex whereas increased mortality has been correlated with female sex. Further investigation into the relationship between estrogen and subsequent clinical measurements of CNS function is needed to develop interventions that may alleviate the pathophysiological consequences of pTBI.

Abstract
Cerebral autoregulation is an intrinsic myogenic response of cerebral vasculature that allows for preservation of stable cerebral blood flow levels in response to changing systemic blood pressure. It is effective across a broad range of blood pressure levels through precapillary vasoconstriction and dilation. Autoregulation is difficult to directly measure and methods to indirectly ascertain cerebral autoregulation status inherently require certain assumptions. Patients with impaired cerebral autoregulation may be at risk of brain ischemia. One of the central mechanisms of ischemia in patients with metabolically compromised states is likely the triggering of spreading depolarization (SD) events and ultimately, terminal (or anoxic) depolarization. Cerebral autoregulation and SD are therefore linked when considering the risk of ischemia. In this scoping review, we will discuss the range of methods to measure cerebral autoregulation, their theoretical strengths and weaknesses, and the available clinical evidence to support their utility. We will then discuss the emerging link between impaired cerebral autoregulation and the occurrence of SD events. Such an approach offers the opportunity to better understand an individual patient's physiology and provide targeted treatments.

Abstract
Intimate partner violence (IPV) is a significant, global public health concern. Women, individuals with historically underrepresented identities, and disabilities are at high risk for IPV and tend to experience severe injuries. There has been growing concern about the risk of exposure to IPV-related head trauma, resulting in IPV-related brain injury (IPV-BI), and its health consequences. Past work suggests that a significant proportion of women exposed to IPV experience IPV-BI, likely representing a distinct phenotype compared with BI of other etiologies. An IPV-BI often co-occurs with psychological trauma and mental health complaints, leading to unique issues related to identifying, prognosticating, and managing IPV-BI outcomes. The goal of this review is to identify important gaps in research and clinical practice in IPV-BI and suggest potential solutions to address them. We summarize IPV research in five key priority areas: (1) unique considerations for IPV-BI study design; (2) understanding non-fatal strangulation as a form of BI; (3) identifying objective biomarkers of IPV-BI; (4) consideration of the chronicity, cumulative and late effects of IPV-BI; and (5) BI as a risk factor for IPV engagement. Our review concludes with a call to action to help investigators develop ecologically valid research studies addressing the identified clinical-research knowledge gaps and strategies to improve care in individuals exposed to IPV-BI. By reducing the current gaps and answering these calls to action, we will approach IPV-BI in a trauma-informed manner, ultimately improving outcomes and quality of life for those impacted by IPV-BI.

Abstract
This study is crucial for improving unilateral spatial neglect (USN) treatments, focusing on comparing the effectiveness of computer-assisted cognitive rehabilitation (CACR) against conventional rehabilitation (CR) methods. It aimed to address a significant research gap and improve patient outcomes by evaluating the impact of CACR versus CR on visuospatial perception, visual field and attention, and visual memory in patients with USN. This study was a randomized controlled trial. Forty-five consecutive patients with USN from a university rehabilitation center were divided into two groups: 22 patients received CACR with Rehacom software, focusing on saccadic eye movement, visual field, and visual-motor coordination, while 23 underwent CR that combined hemispheric activation approach, mental imagery training, and vibration therapy. Assessments included the Motor-Free Visual Perception Test (MVPT), Line Bisection Test (LBT), Visual Span Test (VST), and Visual Recognition Test (VRT). The study employed ANCOVA and effect size calculations to evaluate the effectiveness of CACR compared to CR in treating patients with USN. Results indicated that CACR significantly outperformed CR in improving visuospatial perception, visual field, attention, and memory, showcasing its effectiveness in treating USN. These findings demonstrate the superiority of CACR over CR, particularly in enhancing visual memory and attention, as evidenced by the large effect size in VRT and moderate effects in LBT and VST. This suggests CACR's potential as a more effective approach for rehabilitation in patients with USN due to brain injuries.

Abstract
Nearly 3 million people in the UK have a neurological condition; stroke, traumatic brain injury, Parkinson's disease, multiple sclerosis, brain tumour, motor neurone disease, among others - all affecting the person for the rest of their life. The NHS provides treatment at the onset of a condition but after that, there is a huge need for ongoing support. Research shows that those who are supported and know more about their condition are less likely to have to call on further in-hospital and GP care. There is enormous scope for improving the quality of life for those with neurological conditions. The right support-therapeutic and social-makes all the difference. The book, which this article is based on, shows how those with neurological conditions benefit from integrated ongoing support provided in the local community and self-help, and how lives can be improved. It explains good practice and encouraging methods in the support and treatment of those with life changing conditions.

Abstract
ABSTRACT The Center for Disease Control and Prevention estimates that 75% of reported cases of traumatic brain injury (TBI) are mild, where chronic pain and depression are 2 of the most common symptoms. In this study, we used a murine model of repeated mild TBI to characterize the associated pain hypersensitivity and affective-like behavior and to what extent microglial reactivity contributes to these behavioral phenotypes. Male and female C57BL/6J mice underwent sham or repeated mild traumatic brain injury (rmTBI) and were tested for up to 9 weeks postinjury, where an anti-inflammatory/neuroprotective drug (minocycline) was introduced at 5 weeks postinjury in the drinking water. Repeated mild traumatic brain injury mice developed cold nociceptive hypersensitivity and negative affective states, as well as increased locomotor activity and risk-taking behavior. Minocycline reversed negative affect and pain hypersensitivities in male but not female mice. Repeated mild traumatic brain injury also produced an increase in microglial and brain-derived neurotropic factor mRNA transcripts in limbic structures known to be involved in nociception and affect, but many of these changes were sex dependent. Finally, we show that the antiepileptic drug, gabapentin, produced negative reinforcement in male rmTBI mice that was prevented by minocycline treatment, whereas rmTBI female mice showed a place aversion to gabapentin. Collectively, pain hypersensitivity, increased tonic-aversive pain components, and negative affective states were evident in both male and female rmTBI mice, but suppression of microglial reactivity was only sufficient to reverse behavioral changes in male mice. Neuroinflammation in limbic structures seems to be a contributing factor in behavioral changes resulting from rmTBI.

Abstract
OBJECTIVES Acute symptomatic seizures (ASyS) and epileptiform abnormalities (EAs) on electroencephalography (EEG) are commonly encountered following acute brain injury. Their immediate and long-term management remains poorly investigated. We conducted an international survey to understand their current management. METHODS The cross-sectional web-based survey of 21 fixed-response questions was based on a common clinical encounter: convulsive or suspected ASyS following an acute brain injury. Respondents selected the option that best matched their real-world practice. Respondents completing the survey were compared with those who accessed but did not complete it. RESULTS A total of 783 individuals (44 countries) accessed the survey; 502 completed it. Almost everyone used anti-seizure medications (ASMs) for secondary prophylaxis after convulsive or electrographic ASyS (95.4% and 97.2%, respectively). ASM dose escalation after convulsive ASyS depends on continuous EEG (cEEG) findings: most often increased after electrographic seizures (78% of respondents), followed by lateralized periodic discharges (LPDs; 41%) and sporadic epileptiform discharges (sEDs; 17.5%). If cEEG is unrevealing, one in five respondents discontinue ASMs after a week. In the absence of convulsive and electrographic ASyS, a large proportion of respondents start ASMs due to LPD (66.7%) and sED (44%) on cEEG. At hospital discharge, most respondents (85%) continue ASM without dose change. The recommended duration of outpatient ASM use is as follows: 1-3 months (36%), 3-6 months (30%), 6-12 months (13%), >12 months (11%). Nearly one-third of respondents utilized ancillary testing before outpatient ASM taper, most commonly (79%) a <2 h EEG. Approximately half of respondents had driving restrictions recommended for 6 months after discharge. SIGNIFICANCE ASM use for secondary prophylaxis after convulsive and electrographic ASyS is a universal practice and is continued upon discharge. Outpatient care, particularly the ASM duration, varies significantly. Wide practice heterogeneity in managing acute EAs reflects uncertainty about their significance and management. These results highlight the need for a structured outpatient follow-up and optimized care pathway for patients with ASyS.

Abstract
We tested whether the brain and kidney respond differently to cardiopulmonary bypass (CPB) and to changes in perfusion conditions during CPB. Therefore, in ovine CPB, we assessed regional cerebral oxygen saturation (rSO2 ) by near-infrared spectroscopy and renal cortical and medullary tissue oxygen tension (PO2 ), and, in some protocols, brain tissue PO2 , by phosphorescence lifetime oximetry. During CPB, rSO2 correlated with mixed venous SO2 (r = 0.78) and brain tissue PO2 (r = 0.49) when arterial PO2 was varied. During the first 30 min of CPB, brain tissue PO2 , rSO2 and renal cortical tissue PO2 did not fall, but renal medullary tissue PO2 did. Nevertheless, compared with stable anaesthesia, during stable CPB, rSO2 (66.8 decreasing to 61.3%) and both renal cortical (90.8 decreasing to 43.5 mm Hg) and medullary (44.3 decreasing to 19.2 mm Hg) tissue PO2 were lower. Both rSO2 and renal PO2 increased when pump flow was increased from 60 to 100 mL kg-1 min-1 at a target arterial pressure of 70 mm Hg. They also both increased when pump flow and arterial pressure were increased simultaneously. Neither was significantly altered by partially pulsatile flow. The vasopressor, metaraminol, dose-dependently decreased rSO2 , but increased renal cortical and medullary PO2 . Increasing blood haemoglobin concentration increased rSO2 , but not renal PO2 . We conclude that both the brain and kidney are susceptible to hypoxia during CPB, which can be alleviated by increasing pump flow, even without increasing arterial pressure. However, increasing blood haemoglobin concentration increases brain, but not kidney oxygenation, whereas vasopressor support with metaraminol increases kidney, but not brain oxygenation.

Abstract
Stroke is frequently accompanied by long-term sleep disruption. We therefore aimed to assess the efficacy of digital cognitive behavioural therapy for insomnia to improve sleep after stroke. A parallel group randomised controlled trial was conducted remotely in participant's homes/online. Randomisation was online with minimisation of between-group differences in age and baseline Sleep Condition Indicator-8 score. In total, 86 community-dwelling stroke survivors consented, of whom 84 completed baseline assessments (39 female, mean 5.5 years post-stroke, mean 59 years old), and were randomised to digital cognitive behavioural therapy or control (sleep hygiene information). Follow-up was at post-intervention (mean 75 days after baseline) and 8 weeks later. The primary outcome was self-reported insomnia symptoms, as per the Sleep Condition Indicator-8 (range 0-32, lower numbers indicate more severe insomnia, reliable change 7 points) at post-intervention. There were significant improvements in Sleep Condition Indicator-8 for digital cognitive behavioural therapy compared with control (intention-to-treat, digital cognitive behavioural therapy n = 48, control n = 36, 5 imputed datasets, effect of group p ≤ 0.02,η p 2 = 0.07-0.12 [medium size effect], pooled mean difference = -3.35). Additionally, secondary outcomes showed shorter self-reported sleep-onset latencies and better mood for the digital cognitive behavioural therapy group, but no significant differences for self-efficacy, quality of life or actigraphy-derived sleep parameters. Cost-effectiveness analysis found that digital cognitive behavioural therapy dominates over control (non-significant cost savings and higher quality-adjusted life years). No related serious adverse events were reported to the researchers. Overall, digital cognitive behavioural therapy for insomnia effectively improves sleep after stroke. Future research is needed to assess earlier stages post-stroke, with a longer follow-up period to determine whether it should be included as part of routine post-stroke care.

Abstract
Severe head trauma, with or without polytrauma, subarachnoid haemorrhage due to aneurysm rupture, is an unexpected tragedy for patients and their families. These accidents are likely to result in extremely serious neurological damage, with many of the patients under our care facing a life-threatening prognosis. To protect the brain, one solution is to put the patient into a deep sleep during the so-called "acute" phase, making it impossible to assess the repercussions of the initial injuries at the time: this is what we call "waiting resuscitation".

Abstract
Return to previously valued occupations is a common goal of individuals following acquired brain injury (ABI). However, the focus of rehabilitation is often on self-care and productivity occupations. Return to leisure should be a priority of rehabilitation to support a person's physical, cognitive, social, and emotional well-being. Consequently, the aim of this article was to review the research evidence on engagement in leisure occupations among community-dwelling adults living with ABI. A six-step scoping review was conducted searching five databases. Articles were included if they focused on leisure engagement post-stroke or traumatic brain injury. Seventeen studies were included. Leisure engagement decreased post-ABI with engagement primarily in solitary, sedentary, cognitively inactive, home-based leisure. Leisure engagement was impacted by personal and contextual factors. The findings identify a need to focus on and address changes to leisure following ABI, with exploration of why these changes have occurred beyond personal factors.

Abstract
PURPOSE Providing culturally safe speech-language pathology services to Aboriginal and Torres Strait Islander peoples with acquired communication disorders (ACDs) may be challenging for non-Indigenous speech-language pathologists (SLPs). Indigenous Health Liaison Officers (IHLOs) may share common histories and culture with patients, and provide valuable insights about cultural safety. The study aim was to explore IHLOs' experiences of working with Aboriginal and Torres Strait Islander adults post-stroke or traumatic brain injury (TBI), and with the SLPs who provide services to these peoples. METHOD Using an interpretive description collaborative research design informed by culturally responsive principles, IHLOs (n = 7) participated in interviews facilitated by Aboriginal researchers and the principal investigator. Data were analysed using qualitative content analysis, informed by perspectives of Aboriginal researchers. RESULT Two themes, Connection and Spirit and Emotion, and six interdependent categories described how Aboriginal and Torres Strait Islander peoples have, and need, strong connections to family, country, health professionals, and ACD practices. Without these connections, patients' wellbeing may be deeply affected. CONCLUSION SLPs must collaborate with IHLOs and patients' family members and draw on their cultural knowledge, expertise, and guidance when working with Aboriginal and Torres Strait Islander peoples and ensure connections are created. These connections contribute to culturally safe and responsive speech-language pathology practice.

Abstract
Background: Women in the U.S. military are now authorized to serve in direct combat occupations. This may increase their risk of combat injuries, such as concussion, in future conflicts. Knowledge of sex differences in health profiles after concussion is paramount for military medical planning efforts. The purpose of this study was to assess sex-related differences in health profiles among U.S. military personnel following deployment-related concussion. Materials and Methods: We conducted a retrospective study of service members who sustained a concussion during combat deployment between 2004 and 2013. Postinjury diagnoses were abstracted from outpatient encounters in electronic health records for 24 months after concussion. We used hierarchical clustering to identify clusters, termed "health profiles," and logistic regression to determine whether sex predicted membership in the health profiles. Results: The study sample included 346 women and 4536 men with deployment-related concussion. Five postinjury health profiles were identified and classified as no morbidity, back pain, tinnitus/memory loss, posttraumatic stress disorder/postconcussion syndrome, and multimorbidity. Women relative to men had higher odds of membership in the back pain (odds ratio [OR] = 1.32; 95% confidence interval [CI] = 1.05-1.67) and multimorbidity profiles (OR = 1.44; 95% CI = 1.03-2.00) and lower odds than men in the tinnitus/memory loss profile (OR = 0.62; 95% CI = 0.42-0.91). Conclusions: Postinjury health profiles among U.S. service members differ by sex following deployment-related concussion, particularly with a higher burden of multimorbidity among women than men, which may require interdisciplinary care. Women also had higher odds of membership in the back pain profile and lower odds in the tinnitus/memory loss profile than men. To prepare for future military operations where women may have greater exposure to combat, continued research elucidating health-related sex differences after deployment-related concussion is imperative.

Abstract
Introduction Neonatal and early-life hypoglycaemia, is a frequent finding but is often non-specific and asymptomatic, making detection and diagnosis challenging. Hypoglycaemia-induced cerebral injury can be identified by magnetic resonance imaging (MRI) changes in cerebral white matter, occipital lobes, and posterior parietotemporal regions. It is unknown if children may have hypoglycaemic brain injury secondary to unrecognised hypoglycaemia in early life. We have examined retrospective radiological findings of likely brain injury by neuroimaging to investigate the existence of previous missed hypoglycaemic events. Methods Retrospective MRI data in children in a single tertiary centre, over a ten-year period was reviewed to identify potential cases of unrecognised early-life hypoglycaemia. A detailed search from an electronic radiology repository involved the term "hypoglycaemia'' from text-based reports. The initial report was used for those who required serial scanning. Images specific to relevant reports were further reviewed by a designated paediatric neuroradiologist to confirm likely hypoglycaemia induced brain injury. Medical records of those children were subsequently reviewed to assess if the hypoglycaemia had been diagnosed prior to imaging. Results A total of 107 MR imaging reports were identified for review, and 52 (48.5%) showed typical features strongly suggestive of hypoglycaemic brain injury. Medical note review confirmed no documented clinical information of hypoglycaemia prior to imaging in 22 (42%) patients, raising the likelihood of missed hypoglycaemic events resulting in brain injury. Conclusions We have identified the existence of unrecognised childhood hypoglycaemia through neuroimaging review. This study highlights the need for heightened awareness of early life hypoglycaemia to prevent adverse neurological outcomes later in childhood.

Abstract
Introduction Acute liver failure (ALF) is defined as acute loss of liver function leading to hepatic encephalopathy associated with a high risk of patient death. Brain injury markers in serum and tissue can help detect and monitor ALF-associated brain injury. This study compares different brain injury parameters in plasma and tissue along with the progression of ALF. Method ALF was induced by performing an 85% liver resection. Following the resection, animals were recovered and monitored for up to 48 h or until reaching the predefined endpoint of receiving standard medical therapy (SMT). Blood and serum samples were taken at Tbaseline, T24, and upon reaching the endpoint (Tend). Control animals were euthanized by exsanguination following plasma sampling. Postmortem brain tissue samples were collected from the frontal cortex (FCTx) and cerebellum (Cb) of all animals. Glial fibrillary acidic protein (GFAP) and tau protein and mRNA levels were quantified using ELISA and qRT-PCR in all plasma and brain samples. Plasma neurofilament light (NFL) was also measured using ELISA. Results All ALF animals (n = 4) were euthanized upon showing signs of brain herniation. Evaluation of brain injury biomarkers revealed that GFAP was elevated in ALF animals at T24h and Tend, while Tau and NFL concentrations were unchanged. Moreover, plasma glial fibrillary acidic protein (GFAP) levels were negatively correlated with total protein and positively correlated with both aspartate transaminase (AST) and alkaline phosphatase (AP). Additionally, lower GFAP and tau RNA expressions were observed in the FCTx of the ALF group but not in the CB tissue. Conclusion The current large animal study has identified a strong correlation between GFAP concentration in the blood and markers of ALF. Additionally, the protein and gene expression analyses in the FCTx revealed that this area appears to be susceptible, while the CB is protected from the detrimental impacts of ALF-associated brain swelling. These results warrant further studies to investigate the mechanisms behind this process.

Abstract
OBJECTIVE To examine preinjury life events as moderators of postconcussive symptoms (PCS) and quality of life (QoL) in children with pediatric mild traumatic brain injury (mTBI) versus orthopedic injury (OI). METHODS Participants were 633 children with mTBI and 334 with OI, ages 8-16.99, recruited from 5 pediatric emergency departments and followed for 6 months postinjury as part of a prospective cohort study. Preinjury life events were measured retrospectively using the Child and Adolescent Survey of Experiences, PCS using the Health and Behavior Inventory (HBI) and Post-Concussion Symptom Interview (PCS-I), and QoL using the Pediatric Quality of Life Inventory (PedsQL). Analyses involved longitudinal regression using restricted cubic splines, with group, positive and negative life events, and time as primary predictors. Covariates included age, sex, race, socioeconomic status, preinjury history (i.e., headache, migraine, previous concussion), and parent-rated retrospective PCS-I, HBI, and PedsQL scores. RESULTS PCS and QoL were worse after mTBI than OI, but group differences declined with time (all p < .001). Group differences in PCS were larger at higher levels of positive life events, which predicted lower PCS (p= .03 to p < .001) and higher QoL (p = .048) after OI but not after mTBI. Negative life events predicted worse PCS and QoL in both groups (p = .002 to p < .001). CONCLUSIONS Preinjury positive life events moderate outcomes after pediatric injury, with a protective effect seen in OI but not in mTBI. Negative life events are consistently associated with worse outcomes regardless of injury type.

Abstract
While originally identified as an antiviral pathway, recent work has implicated that cyclic GMP-AMP-synthase-Stimulator of Interferon Genes (cGAS-STING) signaling is playing a critical role in the neuroinflammatory response to traumatic brain injury (TBI). STING activation results in a robust inflammatory response characterized by the production of inflammatory cytokines called interferons, as well as hundreds of interferon stimulated genes (ISGs). Global knock-out (KO) mice inhibiting this pathway display neuroprotection with evidence that this pathway is active days after injury; yet, the early neuroinflammatory events stimulated by STING signaling remain understudied. Furthermore, the source of STING signaling during brain injury is unknown. Using a murine controlled cortical impact (CCI) model of TBI, we investigated the peripheral immune and microglial response to injury utilizing male chimeric and conditional STING KO animals, respectively. We demonstrate that peripheral and microglial STING signaling contribute to negative outcomes in cortical lesion volume, cell death, and functional outcomes postinjury. A reduction in overall peripheral immune cell and neutrophil infiltration at the injury site is STING dependent in these models at 24 h. Transcriptomic analysis at 2 h, when STING is active, reveals that microglia drive an early, distinct transcriptional program to elicit proinflammatory genes including interleukin 1-β (IL-1β), which is lost in conditional knock-out mice. The upregulation of alternative innate immune pathways also occurs after injury in these animals, which supports a complex relationship between brain-resident and peripheral immune cells to coordinate the proinflammatory response and immune cell influx to damaged tissue after injury.

Abstract
BACKGROUND Falls represent a large percentage of hospitalized patients with trauma as they may result in head injuries. Brain injury from ground-level falls (GLFs) in patients is common and has substantial mortality. As fall prevention initiatives have been inconclusive, we changed our strategy to injury prevention. We identified a head protection device (HPD) with impact-resistant technology, which meets head impact criteria sustained in a GLF. HPDs such as helmets are ubiquitous in preventing head injuries in sports and industrial activities; yet, they have not been studied for daily activities. OBJECTIVE We investigated the usability of a novel HPD on patients with head injury in acute care and home contexts to predict future compliance. METHODS A total of 26 individuals who sustained head injuries, wore an HPD in the hospital, while ambulatory and were evaluated at baseline and 2 months post discharge. Clinical and demographic data were collected; a usability survey captured HPD domains. This user experience design revealed patient perceptions, satisfaction, and compliance. Nonparametric tests were used for intragroup comparisons (Wilcoxon signed rank test). Differences between categorical variables including sex, race, and age (age group 1: 55-77 years; age group 2: 78+ years) and compliance were tested using the chi-square test. RESULTS Of the 26 patients enrolled, 12 (46%) were female, 18 (69%) were on anticoagulants, and 25 (96%) were admitted with a head injury due to a GLF. The median age was 77 (IQR 55-92) years. After 2 months, 22 (85%) wore the device with 0 falls and no GLF hospital readmissions. Usability assessment with 26 patients revealed positive scores for the HPD post discharge regarding satisfaction (mean 4.8, SD 0.89), usability (mean 4.23, SD 0.86), effectiveness (mean 4.69, SD 0.54), and relevance (mean 4.12, SD 1.10). Nonparametric tests showed positive results with no significant differences between 2 observations. One issue emerged in the domain of aesthetics; post discharge, 8 (30%) patients had a concern about device weight. Analysis showed differences in patient compliance regarding age (χ12=4.27; P=.04) but not sex (χ12=1.58; P=.23) or race (χ12=0.75; P=.60). Age group 1 was more likely to wear the device for normal daily activities. Patients most often wore the device ambulating, and protection was identified as the primary benefit. CONCLUSIONS The HPD intervention is likely to have reasonably high compliance in a population at risk for GLFs as it was considered usable, protective, and relevant. The feasibility and wearability of the device in patients who are at risk for GLFs will inform future directions, which includes a multicenter study to evaluate device compliance and effectiveness. Our work will guide other institutions in pursuing technologies and interventions that are effective in mitigating injury in the event of a fall in this high-risk population.

Abstract
Balance and functional impairment could occur due to the weakness of the gastrocsoleus muscles in acute stroke patients. This study was planned to determine the muscle architecture and its relationship to balance and functional strength functional ability in patients with acute stroke. A cross-sectional analysis of 22 stroke patients (68.59 ± 8.16) was performed in this study. Gastrocnemius muscle thickness and cross-sectional area were significantly greater on the non-paretic than on the paretic sides (p = 0.004, p = 0.005, respectively). Partial correlation analysis showed that soleus muscle thickness and cross-sectional area was significantly correlated with Berg Balance Scale, Single Leg Stance Test, Five Times Sit to Stand Test and Tandem test results in the paretic side (r = 0.49-0.77, p < 0.05). The gastrocnemius muscle thickness of the non-paretic side had a significant relationship with balance (r = 0.45-0.65, p < 0.05). The muscle thickness and cross-sectional area of the soleus muscle on the paretic sides was significantly related with the functional strength and balance after stroke. It may be beneficial to develop clinical assessment and intervention programs focusing on distal plantar flexor muscle groups in order to improve the functional status and balance.

Abstract
RESEARCH OBJECTIVES 1) Characterize the delivery of programs that support acceptance and resiliency for people with brain injury in the healthcare sector; 2) Understand the barriers and facilitators in implementation of programs to support self-acceptance and resiliency for people with brain injury. DESIGN Participatory focus groups were used to explore experiences of conducting brain injury programs and knowledge of the barriers and facilitators to their implementation. Focus group data were analyzed with manifest content analysis to minimally deviate from broad and structural information provided by participants. SETTING Four focus group sessions were conducted online through a video calling platform. PARTICIPANTS 22 individuals from community associations conducting programs for people with brain injury. Participants were recruited from a public brain injury organization database. RESULTS Systemic challenges such as access to and allocation of funding require navigation support. Resource consistency and availability, including stable program leaders and a welcoming atmosphere, are important for program implementation and sustainability. Shared experiences promote connection with the community and personal development. CONCLUSIONS This study informs individual- and community-level approaches to promote meaningful life after brain injury. Findings highlight existing resources and support future programming for people with brain injury.

Abstract
Introduction Intimate partner violence (IPV) is a global health crisis with 30% of women over the age of 15 experiencing at least one event in their lifetime. Brain injury (BI) due to head impacts and/or strangulation is a common but understudied part of this experience. Previous research has shown BI from other injury mechanisms can disrupt neurovascular coupling (NVC). To gain further insight into whether similar changes occur in this population, we assessed NVC responses in women with a history of IPV-BI. Methods NVC responses were measured for the middle and posterior cerebral arteries (MCA, PCA) using transcranial Doppler ultrasound while participants performed a complex visual search task. The lifetime history of previous exposure to IPV-BI was captured using the Brain Injury Severity Assessment (BISA) along with measures of post-traumatic stress disorder (PTSD), anxiety, depression, substance use, and demographic information. Initial analyses of NVC metrics were completed comparing participants who scored low vs. high on the BISA or did or did not experience non-fatal strangulation followed by a stepwise multiple regression to examine the impact of PTSD, anxiety, and depression on the relationship between the NVC metrics and IPV-BI. Results Baseline and peak cerebral blood velocity were higher and the percentage increase was lower in the PCA in the low compared to the high BISA group whereas no differences between the groups were apparent in the MCA. In addition, those participants who had been strangled had a lower initial slope and area under the curve in the PCA than those who had not experienced strangulation. Finally, the stepwise multiple regression demonstrated the percentage increase in the PCA was significantly related to the BISA score and both depression and anxiety significantly contributed to different components of the NVC response. Conclusions This preliminary study demonstrated that a lifetime history of IPV-BI leads to subtle but significant disruptions to NVC responses which are modulated by comorbid depression and anxiety. Future studies should examine cerebrovascular function at the acute and subacute stages after IPV episodes to shed additional light on this experience and its outcomes.

Abstract
Epidemiological studies of medical comorbidities and possible gender differences associated with traumatic brain injury (TBI) are limited, especially among military veterans. The purpose of this study was to examine relationships between TBI history and a wide range of medical conditions in a large, national sample of veterans, and to explore interactions with gender. Participants of this cross-sectional epidemiological study included 491,604 veterans (9.9% TBI cases; 8.3% women) who enrolled in the VA Million Veteran Program (MVP). Outcomes of interest were medical comorbidities (i.e., neurological, mental health, circulatory, and other medical conditions) assessed using the MVP Baseline Survey, a self-report questionnaire. Logistic regression models adjusting for age and gender showed that veterans with TBI history consistently had significantly higher rates of medical comorbidities than controls, with the greatest differences observed across mental health (odds ratios [ORs] = 2.10-3.61) and neurological (ORs = 1.57-6.08) conditions. Similar patterns were found when evaluating men and women separately. Additionally, significant TBI-by-gender interactions were observed, particularly for mental health and neurological comorbidities, such that men with a history of TBI had greater odds of having several of these conditions than women with a history of TBI. These findings highlight the array of medical comorbidities experienced by veterans with a history of TBI, and illustrate that clinical outcomes differ for men and women with TBI history. Although these results are clinically informative, more research is needed to better understand the role of gender on health conditions in the context of TBI and how gender interacts with other social and cultural factors to influence clinical trajectories following TBI. Ultimately, understanding the biological, psychological, and social mechanisms underlying these comorbidities may help with tailoring TBI treatment by gender and improve quality of life for veterans with TBI history.

Abstract
Sulforaphane (SFN) has attracted much attention due to its ability on antioxidant, anti-inflammatory, and anti-apoptotic properties, while its functional targets and underlying mechanism of action on brain injury caused by acute carbon monoxide poisoning (ACOP) have not been fully elucidated. Herein, we used a systematic network pharmacology approach to explore the mechanism of SFN in the treatment of brain damage after ACOP. In this study, the results of network pharmacology demonstrated that there were a total of 81 effective target genes of SFN and 36 drug-disease targets, which were strongly in connection with autophagy-animal signaling pathway, drug metabolism, and transcription disorders in cancer. Upon the further biological function and KEGG signaling pathway enrichment analysis, a large number of them were involved in neuronal death, reactive oxygen metabolic processes and immune functions. Moreover, based on the results of bioinformatics prediction associated with multiple potential targets and pathways, the AMP-activated protein kinase (AMPK) signaling pathway was selected to elucidate the molecular mechanism of SFN in the treatment of brain injury caused by ACOP. The following molecular docking analysis also confirmed that SFN can bind to AMPKα well through chemical bonds. In addition, an animal model of ACOP was established by exposure to carbon monoxide in a hyperbaric oxygen chamber to verify the predicted results of network pharmacology. We found that the mitochondrial ultrastructure of neurons in rats with ACOP was seriously damaged, and apoptotic cells increased significantly. The histopathological changes were obviously alleviated, apoptosis of cortical neurons was inhibited, and the number of Nissl bodies was increased in the SFN group as compared with the ACOP group (p < .05). Besides, the administration of SFN could increase the expressions of phosphorylated P-AMPK and MFN2 proteins and decrease the levels of DRP1, Caspase3, and Casapase9 proteins in the brain tissue of ACOP rats. These findings suggest that network pharmacology is a useful tool for traditional Chinese medicine (TCM) research, SFN can effectively inhibit apoptosis, protect cortical neurons from the toxicity of carbon monoxide through activating the AMPK pathway and may become a potential therapeutic strategy for brain injury after ACOP.

Abstract
BACKGROUND Impaired discourse production is commonly reported for individuals with traumatic brain injury (TBI). Discourse deficits can negatively impact community integration, return to employment and quality of life. COVID-19 restrictions have reduced in-person assessment services for people with communication impairments. Advances in telehealth may help speech and language therapists (SLTs) to assess monologic discourse more systematically and improve access to services for patients who may find it difficult to attend in-person. AIMS To examine the feasibility of telehealth administration of narrative and procedural discourse tasks with individuals with TBI and matched controls. METHODS & PROCEDURES A total of 20 individuals with TBI and 20 healthy controls, aged 18-55 years, were directly recruited from the UK and indirectly recruited from the US. For participants with TBI, time post-injury was at least 3 months with no diagnosis of aphasia. Control participants were matched for sex and as closely as possible for age. Feasibility of measures was based upon the time to administer both narrative tasks, the report of any technological problems, and participant feed. Discourse samples were transcribed verbatim and analysed using story grammar analysis (for narrative discourse) and identification of propositions (for procedural discourse). Interrater reliability was calculated using percentage agreement for 50% of the data. Non-parametric analyses were used to analyse the performance of the two groups. OUTCOMES & RESULTS Narrative and procedural discourse samples were collected via telehealth in approximately 10 min with no reported technical difficulties or complaints from any participants. For narrative discourse performance, there were significant differences for the TBI and control groups for measures of complete episodes (p < 0.001) and missing episodes (p = 0.005). No significant group differences were noted for any of the procedural discourse measures. CONCLUSIONS & IMPLICATIONS Results support the feasibility of collecting discourse samples via telehealth. Although the participants' discourse performance distinguished the TBI and control groups on the narrative task, no differences between the groups were noted for the procedural task. The narrative discourse task may have been more difficult than the procedural task, or video cue support reduced the cognitive load of the procedural task. This finding suggests the use of more complex procedural tasks without video cue support may be needed. WHAT THIS PAPER ADDS What is already known on this subject Although little research has explored the feasibility of administering discourse assessments for individuals with TBI via telehealth, some studies have found that discourse interventions can be feasibly administered via telehealth. It is also well established that individuals with TBI struggle with the supra-structural and macro-linguistic elements of discourse production. Both procedural and narrative discourse tasks have been found to differentiate individuals with TBI from healthy controls. What this paper adds to existing knowledge Few studies have investigated the feasibility of, and procedures for, administering discourse tasks via telehealth. Additionally, the inclusion of multiple types of discourse tasks to parse cognitive-communication abilities is lacking in the current literature. Findings from this study support that narrative and procedural discourse can be feasibly sampled via telehealth and that international collaboration for research on this topic can facilitate such studies. Individuals with TBI performed more poorly on three measures of narrative discourse. No differences between groups were identified for the procedural task. What are the potential or actual clinical implications of this work? Telehealth assessment for discourse provides flexibility for both the individual with TBI and the speech-language therapist and does not compromise the quality of data collected. The administration of discourse tasks and collection of data was not time-consuming and was well accepted by the study participants. Additionally, international research collaboration not only expands potential participation in research but increases the opportunity to recruit and study more diverse groups.

Abstract
Individuals with a brain injury often require a caregiver to live safely in a community-based setting. This role typically defaults to a woman family member. Under the auspices of a constructivist interpretive tradition that honors a desire-based approach, this study blended narrative inquiry and grounded theory to explore the lived experiences of women caring for loved ones with brain injury. Twenty women completed the semi-structured interview, electing to participate either via videoconferencing or telephone. Employing a constant comparative method, three consecutive rounds of interviews, coding, and analysis occurred. Findings revealed an overarching theme surrounding the intractable challenges and enduring triumphs of caregiving. This discovery further sub-divided into four themes. Two themes focused on traversing a fragmented system of care and managing the burden of caregiving. The remaining two entailed finding supports in family and friends and leveraging professional skillset(s) to optimize caregiving. The recommendations garnered from the women's experiences included enhanced caregiver education with follow-up post-medical care, expanding services into the community to support caregivers and their family members appropriately, and building compassionate networks of women living the caregiving experience. Consistent with a desire-based paradigm, leveraging relationships to triumph over the challenges provided this group of women a voice to promote effective care for self, loved ones, and others.

Abstract
BACKGROUND Intermittent hypoxia (IH) is emerging as a cost-effective nonpharmacological method for vital organ protection. We aimed to assess the effects of a short-term moderate intermittent hypoxia preconditioning protocol (four cycles of 13% hypoxia lasting for 10 min with 5-min normoxia intervals) on acute hypoxic injury induced by sustained hypoxic exposure (oxygen concentration of 11.8% for 6 h). METHODS One hundred healthy volunteers were recruited and randomized to the IH group and the control group to receive IH or sham-IH preconditioning for 5 days, respectively, and then were sent to a hypoxic chamber for simulated acute high-altitude exposure (4500 m). RESULTS The overall incidence of acute mountain sickness was 27% (27/100), with 14% (7/50) in the IH group and 40% (20/50) in the control group (p = 0.003). After 6-h simulated high-altitude exposure, the mean Lake Louise Score was lower in the IH group as compared to controls (1.30 ± 1.27 vs. 2.04 ± 1.89, p = 0.024). Mean peripheral oxygen saturations (SpO2 ) and intracranial pressure (ICP) measures after acute hypoxic exposure exhibited significant differences, with the IH group showing significantly greater SpO2 values (85.47 ± 5.14 vs. 83.10 ± 5.15%, p = 0.026) and lower ICP levels than the control group (115.59 ± 32.15 vs. 130.36 ± 33.83 mmH2 O, p = 0.028). IH preconditioning also showed greater effects on serum protein gene product 9.5 (3.89 vs. 29.16 pg/mL; p = 0.048) and C-reactive protein (-0.28 vs. 0.41 mg/L; p = 0.023). CONCLUSION The short-term moderate IH improved the tolerance to hypoxia and exerted protection against acute hypoxic injury induced by exposure to sustained normobaric hypoxia, which provided a novel method and randomized controlled trial evidence to develop treatments for hypoxia-related disease.

Abstract
BACKGROUND Adults with traumatic brain injuries (TBI) frequently experience cognitive, emotional, physical and communication deficits that require long-term rehabilitation and community support. Although access to rehabilitation services is linked to positive outcomes, there can be barriers to accessing community rehabilitation related to system navigation, referral processes, funding, resource allocation and communications required to ensure access. AIMS This study aimed to identify barriers to accessing insurer funding for rehabilitation and healthcare services, for adults with TBI injured in motor vehicle collisions (MVCs). METHODS We used a co-design approach to collaborate with persons with lived experience to design a survey of adults who sustained a TBI in an MVC. The survey examined access to insurer funding for rehabilitation services and was disseminated through brain injury networks in Ontario, Canada. RESULTS Respondents (n = 148) identified multiple barriers to accessing rehabilitation services through insurer funding, including delays of more than 2 years (49%), mandatory duplicative assessments (64%) and invasion of privacy (55%). Speech-language therapy and neuropsychological services were denied most frequently. Negative experiences included insurers' poor understanding of TBI symptoms, denials of services despite medical evidence demonstrating need and unsupportive insurer interactions. Although 70% of respondents reported cognitive-communication difficulties, accommodations were rarely provided. Respondents identified supports that would improve insurer and healthcare communications and rehabilitation access. CONCLUSION & IMPLICATIONS The insurance claims process had many barriers for adults with TBI, limiting their access to rehabilitation services. Barriers were exacerbated by communication deficits. These findings indicate a role for Speech-language therapists in education, advocacy and communication supports during the insurance process specifically as well as rehabilitation access processes in general. WHAT THIS PAPER ADDS What is already known on this subject There is extensive documentation of the long-term rehabilitation needs of individuals with traumatic brain injury (TBI) and their challenges in accessing rehabilitation services over the long term. It is also well known that many individuals with TBI have cognitive and communication deficits that affect their interactions in the community, including with healthcare providers, and that SLTs can train communication partners to provide communication supports to individuals with TBI in these communication contexts. What this study adds This study adds important information about barriers to accessing rehabilitation, including barriers to accessing SLT services in the community. We asked individuals with TBI about challenges to accessing auto insurance funding for private community services, and their responses illustrate the broader challenges individuals with TBI face in communicating their deficits, conveying service needs, educating and convincing service administrators and self-advocating. The results also highlight the critical role that communication plays in healthcare access interactions, from completing forms to reviewing reports and funding decisions, to managing telephone calls, writing emails and explaining to assessors. What are the clinical implications of this work? This study shows the lived experience of individuals with TBI in overcoming barriers to accessing community rehabilitation. The results show that best practices in intervention should include evaluating rehabilitation access, which is a critical step in patient-centred care. Evaluation of rehabilitation access includes evaluating referral and navigation, resource allocation and healthcare communications, and ensuring accountability at each step, regardless of model of service delivery or funding source. Finally, these findings show the critical role of speech-language therapists in educating, advocating and supporting communications with funding sources, administrators and other healthcare providers.

Abstract
PURPOSE Strategy training is a rehabilitation intervention that aims to enhance problem-solving skills with respect to daily activity-related challenges and has achieved favorable results in Western countries. This study explored the perspectives of individuals with acquired brain injury (ABI) in Taiwan who received strategy training. MATERIALS AND METHODS Semi-structured interviews with community-dwelling adults with ABI were conducted, and reflective memos made by research team members were recorded. Interviews and memos were analyzed through thematic analysis. RESULTS This study included 55 participants. The analysis of the participants' interview responses and memos yielded nine themes under three categories: 1) expectations regarding strategy training, 2) perceived benefits of strategy training, and 3) barriers affecting the process and outcomes of strategy training. CONCLUSIONS All the participants endorsed strategy training through different gains. Most participants' expectations before the intervention were uncertain. Including family members into the strategy training is of key importance for a successfulness of their goals. The participants' experiences about strategy training were affected by various barriers (i.e., health and medical problems, the physical environment, and natural events). Clinicians and researchers should consider these expectations, benefits, and barriers when studying and implementing strategy training in non-Western contexts.IMPLICATIONS FOR REHABILITATIONStrategy training provides clients the opportunity to actively engage in their own goal setting and decision making.Strategy training increases the client's confidence in their ability to participate in the community, communicate, and perform daily living and physical activities.Therapists should consider the health conditions and physical environment of clients when helping them set goals and before facilitating their engagement in the community.Taiwanese family members play a crucial role in supporting acquired brain injury survivors in strategy training.

Abstract
BACKGROUND People with an acquired brain injury (ABI) find it challenging to use social media due to changes in their cognition and communication skills. Using social media can provide opportunities for positive connection, but there is a lack of interventions specifically designed to support safe and successful social media use after ABI. AIMS To investigate the outcomes of completing a social media skills intervention and identify barriers and facilitators for future implementation. METHODS & PROCEDURES The study used a mixed-methods, pre-post-intervention design. A total of 17 adults with an ABI were recruited. Participants completed an intervention that included a short self-guided course about social media skills (social-ABI-lity course), and then participated in a private, moderated Facebook group over a 12-week period (social-ABI-lity Facebook group). Data were collected over this period through observation of group activity and weekly surveys. They were also collected on social media use and quality of life at pre-intervention, post-intervention and after 3 months. Participants provided feedback on the experience of participating in the programme via a post-intervention interview. OUTCOMES & RESULTS At post-intervention, there were significant improvements in confidence in using Facebook (p = 0.002) and enjoyment of using Facebook to connect with others (p = 0.013). There was no significant change in reported quality of life, although participants described the multiple benefits of connection they perceived from involvement in the group. Observational data and feedback interviews were informative about the feasibility and acceptability of the intervention. CONCLUSIONS & IMPLICATIONS This pilot study provided preliminary evidence that an intervention comprising a short, self-guided training course and a private, moderated Facebook group improved outcomes for people with ABI. Key recommendations for future implementation include embedding active peer moderators within groups and taking an individualized approach to delivery of the intervention. WHAT THIS PAPER ADDS What is already known on the subject Research has documented the challenges that people with ABI experience in using social media, and the difficulty for rehabilitation clinicians in providing appropriate support in this field. What this paper adds to existing knowledge This pilot study reports the outcomes of people with ABI completing a short, self-guided social media skills course and participating in a private, moderated Facebook group. After the intervention, participants reported significantly increased confidence and enjoyment in using Facebook, described the benefits of connection found in the groups, and suggested potential improvements for future implementation. What are the potential or actual clinical implications of this work? With the growing use of social media for connection and participation, there is a professional obligation to address social media communication skills in cognitive-communication rehabilitation for people with ABI. The findings of this study will inform interventions and future research to assist people with ABI to build their social media skills for communication, social support and a sense of connection.

Abstract
BACKGROUND Rehabilitation for cognitive-communication impairments following brain injury can be complex given the heterogenous nature of impairments post injury. Project-based intervention has the potential to improve communication skills and create a meaningful real-life context where individuals collaborate to develop a concrete product, which benefits others. While evidence for this intervention is emerging, the COVID-19 pandemic prompted increased use of telehealth interventions to serve people with brain injury. This paper aims to describe a framework for the delivery of project-based intervention via telehealth within community rehabilitation settings; and present several case studies of telehealth groups completed in the United Kingdom and the United States during the COVID-19 pandemic. METHODS A working group was formed to map the components of project-based intervention onto the rehabilitation treatment specification system (RTSS). This system is a conceptual framework that helps to explain the link between treatment theory and ingredients, allowing a clinician to clearly understand how and why a treatment works. First, a literature search was completed to identify eligible studies on project-based intervention after brain injury. Second, those studies were thematically mapped onto the RTSS to identify important intervention components. Third, the presence of these components was assessed for community brain injury groups delivered via telehealth in the United Kingdom and United States. These groups were further described using a taxonomy of social activities that help to describe the degree of meaningful social engagement. RESULTS The literature was described with a thematic RTSS summary. Treatment aims focus on skills training and self-efficacy, advocacy and self-empowerment, emotional well-being and quality of life, and collaboration and community belonging. Treatment ingredients involve a range of cognitive and behavioural supports to deliver meaningful activities and contexts to complete a project. Mechanisms of action involve learning by doing and cognitive and affective information processing. All four telehealth groups conducted in the United Kingdom and United States involved at least three treatment aims, >7 targets, and >8 treatment ingredients. All groups reported positive experiences from activities that involve working collaboratively to help others and contribute to society. CONCLUSIONS Project-based intervention delivered via telehealth has the potential for supporting people with acquired brain injury to improve their communication skills and engage in meaningful, collaborative activity. Application of the RTSS helps clinicians to understand the aims and therapeutic ingredients (or clinician activities) through which a person with brain injury may achieve specific treatment targets during the rehabilitation process. WHAT THIS PAPER ADDS What is already known on the subject Project-based interventions have the potential to improve cognitive, self-regulatory, behavioural and social communication skills, renegotiate identity and reaffirm sense of self, providing a positive impact on quality of life for persons with acquired brain injuries. Projects serve as a context for meaningful engagement for individuals in the chronic phase of traumatic brain injury recovery, without fulfilling work, family or social responsibilities. However, most published research has involved in-person projects and few projects have been delivered via telehealth. What this paper adds to existing knowledge While past published works have shared core principles of intervention, a variety of projects, durations, dosages and methods have been employed. The current paper provides a framework to support more consistent implementation. By mapping previous project-based interventions to the RTSS, clinicians will have a better understanding of the aims, targets, ingredients and theoretical underpinnings of project-based interventions. In the wake of the COVID-19 pandemic, the shift to telehealth moved interventions to a virtual context. The four case projects in this paper demonstrate that it is possible to conduct project-based interventions via telehealth and provides a clear description to guide clinicians in their delivery. What are the potential or actual clinical implications of this work? This work begins to build the foundation for more rigorous, empirical examination of project-based interventions. By mapping project-based interventions to the RTSS, core aims, targets and ingredients are established that can be objectively examined. This investigation also provides a road map for clinicians who wish to implement this complex intervention.

Abstract
BACKGROUND Peroxiredoxin 2 (Prx2), an intracellular protein that regulates redox reactions, released from red blood cells is involved in inflammatory brain injury after intracerebral hemorrhage (ICH). Toll-like receptor 4 (TLR4) may be crucial in this process. This study investigated the role of the Prx2-TLR4 inflammatory axis in brain injury following experimental ICH in mice. METHODS First, C57BL/6 mice received an intracaudate injection of autologous arterial blood or saline and their brains were harvested on day 1 to measure Prx2 levels. Second, mice received an intracaudate injection of either recombinant mouse Prx2 or saline. Third, the mice were co-injected with autologous arterial blood and conoidin A, a Prx2 inhibitor, or vehicle. Fourth, the mice received a Prx2 injection and were treated with TAK-242, a TLR4 antagonist, or saline (intraperitoneally). Behavioral tests, magnetic resonance imaging, western blot, immunohistochemistry/immunofluorescence staining, and RNA sequencing (RNA-seq) were performed. RESULTS Brain Prx2 levels were elevated after autologous arterial blood injection. Intracaudate injection of Prx2 caused brain swelling, microglial activation, neutrophil infiltration, neuronal death, and neurological deficits. Co-injection of conoidin A attenuated autologous arterial blood-induced brain injury. TLR4 was expressed on the surface of microglia/macrophages and neutrophils and participated in Prx2-induced inflammation. TAK-242 treatment attenuated Prx2-induced inflammation and neurological deficits. CONCLUSIONS Prx2 can cause brain injury following ICH through the TLR4 pathway, revealing the Prx2-TLR4 inflammatory axis as a potential therapeutic target.

Abstract
Caseinolytic peptidase B homolog (CLPB) is a mitochondrial protein which is highly expressed in brain. Its deficiency may be associated with severe neonatal encephalopathy. This report describes a case of fatal neonatal encephalopathy associated with biallelic stop-gain mutation in CLPB (NM_001258392.3:c.1159C>T/p.Arg387*). Neurologic disorder encompasses pre- and post-natal features including polyhydramnios, intrauterine growth restriction, respiratory insufficiency, lethargy, excessive startle reflex, generalized hypertonia, and epileptic seizures. Brain macroscopic examination demonstrates frontal severe periventricular cystic leukoencephalopathy, along with mild ex-vacuo tri-ventricular dilatation. The most striking immunohistopathologic features are striato-thalamic neurodegeneration and deep white matter loss associated with strong reactive astrogliosis. This report supports that CLPB deficiency should be considered among the neurometabolic disorders associated with severe prenatal-onset neurologic impairment that may result from cystic leukoencephalopathy.

Abstract
The aim of this article is to review the application progress of proteomics technology in brain injury research in recent years, point out the current problems that need to be overcome, and explore the application prospects of proteomics analysis in brain injury. This study also aims to retrieve all literature on brain injury and proteomics and summarize it. Through searching and screening, the widespread application of proteomics technology in the treatment of traumatic brain injury (TBI) and the use of a large number of TBI biomarkers were discovered. The pathways mediated by some biomarkers and the physiological and pathological mechanisms of occurrence were elucidated. The current classification of brain injury is mainly based on subjective evaluation of clinical symptoms, combined with objective imaging. However, its practical value is often limited when applied to prognosis evaluation in brain injury. Proteomics technology can make up for this deficiency and provide a reference for the prevention and treatment of brain injury.

Abstract
OBJECTIVE To describe the characteristics and outcomes of older (65+) Medicare beneficiaries with traumatic brain injury (TBI) treated in inpatient rehabilitation facilities between 2013 and 2018. DESIGN Descriptive study using IRF Patient Assessment Instrument (IRF-PAI) data reporting trends of the sociodemographic and clinical characteristics and outcomes of inpatient rehabilitation facilities Medicare patients with TBI. SETTING Inpatient rehabilitation facilities in the United States PARTICIPANTS: 99,804 older Medicare fee-for-service and Medicare Advantage patients with TBI. INTERVENTIONS Not applicable MAIN OUTCOME MEASURES: Length of stay, self-care and mobility functional outcomes, discharge destination. RESULTS The number of older Medicare beneficiaries with TBI treated in inpatient rehabilitation facilities increased from 14,657 in 2013 to 18,791 in 2018, an increase of 28.2%. In addition to this overall increase in patients, we also found the percentage of males increased slightly (52.9% to 54.8%), there was a higher percentage of patients with tier 3 comorbidities, there was a decrease in the variability of length of stay, there was slightly more self-care and mobility improvement and a slightly higher percentage of patients discharged to the community (67.8% in 2013 and 71.6% in 2018). Newer standardized data showed that prior to the injury, more than one-third used a walker and more than three-quarters had a history of recent falls. CONCLUSIONS Between 2013 and 2018, the number of Medicare beneficiaries with TBI treated in IRFs increased by approximately 28 percent. The characteristics of IRF older patients with TBI changed between 2013 and 2018 toward a slightly higher proportion of males, more comorbidities, and a higher percentage being discharged home after inpatient rehabilitation.

Abstract
OBJECTIVE The goal of this study is to examine the effectiveness of case management services for a population of justice-involved individuals with TBI history. METHODS Two thousand three hundred and eighty-nine records from statewide behavioral health and brain injury program databases were used in two studies. RESULTS Participants with a reported TBI history were more likely to have experienced trauma and to have a behavioral health diagnosis relative to incarcerated persons without TBI. Six months after release, 56.8% of participants with a history of TBI were still receiving community treatment, 27.8% were not in treatment, and 3.4% had completed treatment. There was a high attrition rate; 70% of people referred for case management failed to maintain contact. CONCLUSIONS For those that did receive services, these data suggest that it prevented an escalation of psychosocial needs. There were no differences in community participation as measured by the Mayo Portland Adaptability Index's Participation Index (M2PI) scores (t24 = .497, p = 0.624) at intake and after 6 months of case management. This study confirms that case management confers a benefit to persons with TBI who are released from the criminal justice system. Further, recidivism rates for this vulnerable group were no different from the larger population of returning citizens.

Abstract
Clinical conversations surrounding the continuation or limitation of life-sustaining treatments (LLST) are both challenging and tragically necessary for patients with Disorders of Consciousness (DoC) following severe brain injury. Divergent cultural, philosophical, and religious perspectives contribute to vast heterogeneity in clinical approaches to LLST - as reflected in regional differences and inter-clinician variability. Here we provide an ethical analysis of factors that inform LLST decisions among patients with DoC. We begin by introducing the clinical and ethical challenge and clarifying the distinction between withdrawing and withholding life-sustaining therapy. We then describe relevant factors that influence LLST decision-making including diagnostic and prognostic uncertainty, perception of pain, defining a "good" outcome, and the role of clinicians. In concluding sections, we explore global variation in LLST practices as they pertain to patients with DoC and examine the impact of religious perspectives on approaches to LLST. Understanding and respecting the cultural and religious perspectives of patients and surrogates is essential for protecting patient autonomy and advancing goal-concordant care during critical moments of medical decision making.

Abstract
Healthcare professionals use various technologies to evaluate and support patients who have suffered severe brain injuries. They integrate monitoring and sensory assessments into their clinical practice, and these assessments can have an impact on treatment decisions and prognostication. Responses from patients during different interactions are interpreted as "signs of consciousness" when considered contextually relevant. This study is based on anthropological fieldwork conducted in specialized Danish intensive care units, where we explore how signs of consciousness are made to count through practices of enactment. We ethnographically trace how the clinical concept of potential influences the interpretation of signs of consciousness as a complex biosocial practice based on the biomedical assumption that consciousness is a vital indicator of what makes a life. The article provides insights into the potential for recovery as an emergent biosocial practice and contributes to a broader discussion within medical anthropology of the moral landscapes of clinical and experimental borderlands.

Abstract
OBJECTIVE To summarize the best evidence-based strategies for the management of cognitive dysfunction in patients with brain injury and to provide a reference for clinical nursing practice. DESIGN Review. METHODS The review was presented using PRISMA guidelines. A systematic search of evidence on the management of cognitive dysfunction in patients with brain injury was conducted in computerized decision systems, guideline websites, professional association websites and comprehensive databases from the date of creation to 21 June 2023. The types of evidence included were clinical decision making, guidelines, evidence summaries, best practices, recommended practices, expert consensus, systematic reviews and meta-analyses. Two researchers trained in evidence-based methodological systems independently evaluated the quality of the literature and extracted, integrated and graded the evidence for inclusion. RESULTS A total of 20 articles were selected, including nine guidelines, three expert consensus articles, one clinical practice article and seven systematic reviews, and the overall quality of the literature was high. Thirty pieces of evidence were summarized in seven areas: assessment, multidisciplinary team, rehabilitation program, cognitive intervention, exercise intervention, music intervention and medication management. CONCLUSIONS This study summarizes the latest evidence on the management of cognitive dysfunction in the care of adults with brain injury and provides a reference for clinical nursing practice. The best evidence should be selected for localized and individualized application in clinical work, and the best evidence should be continuously updated to standardize nursing practice. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE Patients with cognitive impairment after brain injury often suffer from memory loss, attention deficit and disorientation and are unable to have a normal life and experience much enjoyment, which seriously affects their physical and mental health and creates a great burden of care for their families and society. Best evidence-based strategies for the nursing management of cognitive impairment in brain injury are essential for standardizing clinical nursing practice and providing timely, professional, systematic and comprehensive nursing interventions for patients. REPORTING METHOD This review is reported following the PRISMA 2020 statement guidelines, as applicable, to enhance transparency in reporting the evidence synthesis. TRIAL AND PROTOCOL REGISTRATION This study has been registered with the Fudan University Centre for Evidence-based Nursing, a JBI Centre of Excellence under registration number ES20232566, http://ebn.nursing.fudan.edu.cn/myRegisterList. PATIENT OR PUBLIC CONTRIBUTION No patient or public contribution.

Abstract
The objective was to develop an interdisciplinary weaning protocol (IWP) for patients with tracheostomy tubes due to acquired brain injury, and to effect evaluate implementation of the IWP on decannulation rates and weaning duration. An expert panel completed a literature review in 2018 to identify essential criteria in the weaning process. Based on consensus and availability in clinical practice, criteria for guiding the weaning process were included in the protocol. Using the IWP, dysphagia is graded as either severe, moderate, or mild. The weaning process is guided through a protocol which specified the daily duration of cuff deflation until decannulation, along with recommendations for treatment and rehabilitation interventions. Data from 337 patient records (161 before and 176 after implementation) were included for effect evaluation. Decannulation rate during hospitalization was unchanged at 91% vs. 90% before and after implementation (decannulation rate at 60 days was 68% vs. 74%). After implementation, the weaning duration had decreased compared to before implementation, hazard ratio 1.309 (95%CI: 1.013; 1.693), without any increased risk of tube-reinsertion or pneumonia. Furthermore, a tendency toward decreased length of stay was seen with median 102 days (IQR: 73-138) and median 90 days (IQR: 58-119) (p = 0.061) before and after implementation, respectively. Scientific debate on weaning protocols for tracheostomy tubes are encouraged.
