Post-traumatic stress disorder and self-reported outcomes after traumatic brain injury in victims of assault

Distinct trajectories of neuropsychiatric symptoms in the 12 months following traumatic brain injury (TBI): a TRACK-TBI study

BACKGROUND

Neuropsychiatric symptoms are common after traumatic brain injury (TBI) and often resolve within 3 months post-injury. However, the degree to which individual patients follow this course is unknown. We characterized trajectories of neuropsychiatric symptoms over 12 months post-TBI. We hypothesized that a substantial proportion of individuals would display trajectories distinct from the group-average course, with some exhibiting less favorable courses.

METHODS

Participants were level 1 trauma center patients with TBI (n = 1943), orthopedic trauma controls (n = 257), and non-injured friend controls (n = 300). Trajectories of six symptom dimensions (Depression, Anxiety, Fear, Sleep, Physical, and Pain) were identified using growth mixture modeling from 2 weeks to 12 months post-injury.

RESULTS

Depression, Anxiety, Fear, and Physical symptoms displayed three trajectories: Stable-Low (86.2-88.6%), Worsening (5.6-10.9%), and Improving (2.6-6.4%). Among symptomatic trajectories (Worsening, Improving), lower-severity TBI was associated with higher prevalence of elevated symptoms at 2 weeks that steadily resolved over 12 months compared to all other groups, whereas higher-severity TBI was associated with higher prevalence of symptoms that gradually worsened from 3-12 months. Sleep and Pain displayed more variable recovery courses, and the most common trajectory entailed an average level of problems that remained stable over time (Stable-Average; 46.7-82.6%). Symptomatic Sleep and Pain trajectories (Stable-Average, Improving) were more common in traumatically injured groups.

CONCLUSIONS

Findings illustrate the nature and rates of distinct neuropsychiatric symptom trajectories and their relationship to traumatic injuries. Providers may use these results as a referent for gauging typical v. atypical recovery in the first 12 months post-injury.

Posttraumatic Growth, Maladaptive Cognitive Schemas and Psychological Distress in Individuals Involved in Road Traffic Accidents-A Conservation of Resources Theory Perspective

Road traffic accidents can have profound psychological impacts on the individuals involved, encompassing both negative distress and positive growth. This study, guided by the conservation of resources (COR) theory, investigates the intricate relationship between posttraumatic growth (PTG), maladaptive cognitive schemas, and psychological distress in individuals involved in road traffic accidents. PTG reflects an individual's ability to derive positive changes from adversity, while maladaptive schemas represent negative cognitive patterns. Using a 122 sample of individuals involved in road traffic accidents, we examined direct and indirect effects within this complex network. Our findings reveal significant direct effects of PTG on psychological distress (β = 0.101, p = 0.02). Particularly noteworthy are the indirect effects mediated by cognitive schemas, emphasizing the role of impaired autonomy and perceived performance deficiencies (β = 0.102, p = 0.05). This suggests that individuals involved in road traffic accidents experiencing higher PTG levels may indirectly experience greater psychological distress through these maladaptive cognitive schemas. This study not only advances our understanding of the psychological consequences of road traffic accidents but also aligns with self-determination theory, emphasizing autonomy and competence as fundamental needs. Individuals involved in road traffic accidents may undergo profound shifts in perspective following the trauma, which our results support. Recognizing the nuanced relationship between PTG, maladaptive cognitive schemas, and psychological distress is crucial for tailoring interventions and support systems for individuals involved in traffic accidents. As PTG can coexist with distress, interventions should foster adaptive growth while addressing maladaptive schemas to promote resilience in the face of traumatic events.

Changing trends and characteristics of one punch deaths in Australia (2012-2018)

One-punch assaults also known as 'coward punches', are characterised by a single severe blow to the head causing the victim to lose consciousness, resulting in a secondary impact between the head and surrounding environment. Such impacts may result in brain injury leading to fatality or permanent neurological impairment. In a previous publication, there were 90 one punch deaths around Australia between 2000 and 2012, mostly involving young men drinking alcohol at a licensed venue at the weekend. This prompted a surge of public education and awareness campaigns around Australia, in addition to regulatory and legislative changes aimed at curbing social violence. This retrospective descriptive study aimed to examine one punch deaths since 2012 in Australia to determine if there has been a decrease in deaths, and whether the demographics and circumstances of these deaths have changed. A search of the National Coronial Information System was undertaken for all closed coronial cases between 1 January 2012 and 31 December 2018. Additional information was collected from medicolegal reports including toxicology, pathology and coronial findings. There were 80 one punch fatalities in Australia, almost exclusively involving males. The median age was 43.5 (range 18-71) years and there was a decreasing trend in the number of deaths annually. Most fatal assaults occurred in the state of New South Wales (28.8%) followed by Queensland (23.8%), and in metropolitan locations (64.6%) rather than regional areas (35.4%). Alcohol was the most commonly detected drug, found in 47 cases of the 71 cases where toxicology results were available (66%), with a median concentration of 0.14 and 0.19 g/100 mL in antemortem and postmortem samples, respectively (range 0.005-0.32 g/100 mL). Five deaths reported methylamphetamine, with THC detected in 21.1% of cases. Assaults more commonly occurred on a footpath or roadside (41.3%), followed by a home or dwelling (32.5%). 8.8% of assaults occurred inside hotels, bars or other licenced venues. Most transpired on a weekday, which differed from the pre-2012 period when these assaults occurred mainly on the weekend. While some trends are positive, there has been a shift in the victim demographic as well as the typical environment for fatal one punch assaults, highlighting the importance of public health surveillance in providing a current evidence base to inform policy and practice.

Effects of the Response to the COVID-19 Pandemic on Assault-Related Head Injury in Melbourne: A Retrospective Study

Assault is the leading preventable cause of death, traumatic brain injury (TBI), and associated mental health problems. The COVID-19 pandemic has had a profound impact on patterns of interpersonal violence across the world. In this retrospective cross-sectional study, we analysed medical records of 1232 assault victims (domestic violence: 111, random assault: 900, prison assault: 221) with head injuries who presented to the emergency department (ED) at St Vincent's Hospital in Melbourne, Australia, a city with one of the longest and most severe COVID-19 restrictions worldwide. We examined changes in prevalence in the assault group overall and in domestic violence, random assault, and prison assault victims, comparing data from 19.5 months before and after the first day of COVID-19 restrictions in Melbourne. Moreover, we investigated differences driven by demographic factors (Who: age group, sex, and nationality) and clinical variables (Where: assault location, and When: time of arrival to the ED and time from moment of injury until presentation at ED). Descriptive statistics and chi-square analyses were performed. We found the COVID-19 pandemic significantly affected the Where of assault-related TBI, with a shift in the location of assaults from the street to the home, and the increase at home being driven by random assaults on middle-aged adults. Overall, we observed that 86% of the random assault cases were males, whereas 74% of the domestic assault cases were females. Meanwhile, nearly half (44%) of the random assault victims reported alcohol consumption versus a fifth (20%) of domestic violence victims. These findings will have direct implications for developing screening tools and better preventive and ameliorative interventions to manage the sequelae of assault TBI, particularly in the context of future large-scale health crises or emergencies.

Post-concussion symptoms 1-year after traumatic brain injury: using the Rivermead Post-concussion Questionnaire to identify predictors of severity

BACKGROUND

Patients who suffer traumatic brain injury (TBI) often experience a constellation of physical, cognitive, and emotional/behavioral symptoms called "post-concussion symptoms" and subsequent long-term disability. This study aimed to investigate the incidence of persistent post-concussion symptoms and possible predictors of long-term disability focusing on demographic, injury, and psychological factors. It was hoped to identify groups at high risk.

METHODS

A prospective cohort of 1322 individuals admitted with TBI were assessed in a specialist neurorehabilitation clinic at 10 weeks and 1-year post injury between August 2011 and July 2015. The outcome (post-concussion symptoms) was measured using the Rivermead Post-concussion Questionnaire (RPQ) at 1-year post injury.

RESULTS

At 1 yr, 1131 individuals were identified (>90% follow-up). Over 20% exhibited moderate or severe symptom levels on RPQ. A linear regression model showed that previous psychiatric history, lower Glasgow Coma Scale (GCS), severe CT abnormalities, injury caused by assault, pre-injury unemployment, and inability to return to work at 6 weeks post-injury were associated with worse symptoms at 1 yr. The adjusted R² of the model was 25.1%.

CONCLUSION

These findings confirm the high incidence of post-concussion symptoms at 1 yr and identify certain associated features that increase risk. This may allow targeting of certain groups, e.g., return to work or victims of assault.

Caregiver Characteristics of Adults with Acute Traumatic Brain Injury in the United States and Latin America

Objectives: To compare characteristics of caregivers of adults with acute traumatic brain injury (TBI) in the U.S. and Latin America (Mexico and Colombia). Design: Secondary data analysis of two cohorts. Cohort 1: English-speaking caregivers of adults with TBI in the U.S. (n = 80). Cohort 2: Spanish-speaking caregivers of adults with TBI in Mexico or Colombia (n = 109). Results: Similarities between the U.S. and Latin American caregiver groups, respectively, were: predominantly women (81.3%, 81.7%, respectively); spouses/domestic partners (45%, 31.2%); and motor vehicle accident (41.5%, 48.6%) followed by fall etiologies (40%, 21.1%). Differences between U.S. and Latin American caregivers were: age (49.5 years, 41.5 years, p < 0.001); employment status ((Χ52 = 59.63, p < 0.001), full-time employment (63.7%, 25.7%), homemaker (2.5%, 31.2%), and retired (17.5%, 1.8%)); violence-related etiology (2.5%, 15.6%); and severity of depressive symptoms (M = 7.9, SD = 5.8; M = 5.8, SD = 5.7; p = 0.014). Conclusions: TBI caregivers in the U.S. were older and employed full-time or retired more often than those in Latin America. Violence-related etiology was nearly five times more common in Latin America, raising concerns for potential implications of post-traumatic stress and family adjustment after injury. Although both groups likely could use mental health support, this was particularly true of the U.S. cohort, maybe due to differential demographics, mechanisms of injury, or family and community support.

Examining the Association Between Childhood Trauma, Brain Injury, and Neurobehavioral Symptoms Among Survivors of Intimate Partner Violence: A Cross-Sectional Analysis

OBJECTIVE

Understanding factors contributing to neurobehavioral symptom burden among intimate partner violence (IPV) survivors has important implications for prevention, screening, and intervention in this vulnerable population. This study aimed to (1) identify the relationship between childhood trauma and neurobehavioral symptoms among a shelter- and community-based sample of IPV survivors, including investigating the mediating role of posttraumatic stress symptoms and alexithymia in this relationship; (2) assess the association between IPV-related brain injury (BI) severity and neurobehavioral symptoms; and (3) assesses whether physical, emotional, or cognitive domains of neurobehavioral symptom burden show differential associations with childhood trauma or IPV-related BI.

SETTING

Community sites serving women who had experienced IPV such as domestic violence shelters and transitional housing sites.

PARTICIPANTS

Women survivors of IPV with and without BI (n = 99), aged 18 to 54 years.

DESIGN

Retrospective, cross-sectional study design.

MEASURES

The following self-reported questionnaires were used: Rivermead Post Concussion Questionnaire (RPQ); Childhood Trauma Questionnaire (CTQ); a modified version of the Conflict Tactics Scale; Brain Injury Severity Assessment (BISA); Clinician-Administered PTSD Scale for DSM IV; and Toronto Alexithymia Scale. The final multivariate regression model assessed the association between childhood abuse, BI severity, and neurobehavioral symptoms (as measured by the RPQ) adjusting for age, educational attainment, and abuse in the past year. We created separate models with total neurobehavioral symptom score as an outcome, as well as somatic, emotional, and cognitive symptom scores. We used structural equation modeling to assess whether posttraumatic stress and alexithymia mediated the effect of childhood trauma and neurobehavioral symptoms.

RESULTS

Childhood trauma was associated with higher levels (P < .01) of overall neurobehavioral symptom burden in women independent of BI and specifically associated with RPQ Emotional and Somatic subscale symptoms (P ≤ .05). BI was positively associated with somatic symptoms in the full sample and cognitive neurobehavioral symptoms in the sample of women with IPV-related BI (P < .05) independent of childhood trauma. Posttraumatic stress symptoms, but not alexithymia, partially mediated the effect of childhood trauma effect on neurobehavioral symptoms.

CONCLUSION

Childhood trauma and BI should not be overlooked as part of efforts to meet the needs of IPV survivors who may experience a range of emotional, somatic, and cognitive symptoms.

The prevalence, characteristics, and psychiatric correlates of traumatic brain injury in incarcerated individuals: an examination in two independent samples

PRIMARY OBJECTIVE

Identify the prevalence, characteristics, and psychological correlates of traumatic brain injury (TBI) among incarcerated individuals.

RESEARCH DESIGN

Three aims: (1) Determine the prevalence and characteristics of TBI in 1469 adults incarcerated in Wisconsin state prisons (1064 men, 405 women); (2) Characterize the relationship between mild TBI and mental illness in a sub-sample of men and women; (3) Reproduce the findings from Aim 1 and Aim 2 in an independent sample of 1015 adults incarcerated in New Mexico state prisons (600 men, 415 women).

METHODS AND PROCEDURES

Standardized TBI assessment with structured clinical interviews and self-report questionnaires.

MAIN OUTCOMES AND RESULTS

Rates of TBI were approximately five times greater than the general population, with a substantially higher rate of TBI caused by assault. In the Wisconsin sample, mild TBI was associated with greater levels of post-traumatic stress disorder (PTSD) among women (but not among men). In the New Mexico sample, TBI of any severity was associated with greater levels of major depressive disorder (MDD) among women (but not among men).

CONCLUSIONS

This study thus provides novel data on TBI and its correlates among individuals incarcerated in state prisons, and highlights a specific treatment need within the prison population.

Patient reported outcomes 6 to 12 months after interpersonal violence: A multicenter cohort study

PURPOSE

Violence continues to be a significant public health burden, but little is known about the long-term outcomes of these patients. Our goal was to determine the impact of violence-related trauma on long-term functional and psychosocial outcomes.

METHODS

We identified trauma patients with moderate to severe injuries (Injury Severity Score, ≥9) treated at one of three level 1 trauma centers. These patients were asked to complete a survey over the phone between 6 and 12 months after injury evaluating both functional and psychosocial outcomes (12-item Short Form Survey, Trauma Quality of Life, posttraumatic stress disorder [PTSD] screen, chronic pain, return to work). Patients were classified as having suffered a violent injury if the mechanism of injury was a stab, gunshot, or assault. Self-inflicted wounds were excluded. Adjusted logistic regression models were built to determine the association between a violent mechanism of injury and long-term outcomes.

RESULTS

A total of 1,050 moderate to severely injured patients were successfully followed, of whom 176 (16.8%) were victims of violence. For the victims of violence, mean age was 34.4 years (SD, 12.5 years), 85% were male, and 57.5% were Black; 30.7% reported newly needing help with at least one activity of daily living after the violence-related event. Fifty-nine (49.2%) of 120 patients who were working before their injury had not yet returned to work; 47.1% screened positive for PTSD, and 52.3% reported chronic pain. On multivariate analysis, a violent mechanism was significantly associated with PTSD (odds ratio, 2.57; 95% confidence interval, 1.59-4.17; p < 0.001) but not associated with chronic pain, return to work, or functional outcomes.

CONCLUSION

The physical and mental health burden after violence-related trauma is not insignificant. Further work is needed to identify intervention strategies and social support systems that may be beneficial to reduce this burden.

LEVEL OF EVIDENCE

Prognostic and epidemiological, level III.

Associations between physical health conditions and posttraumatic stress disorder according to age

OBJECTIVES

Posttraumatic stress disorder (PTSD) is associated with various physical health conditions. However, it is unclear whether the relationship between PTSD and physical health conditions differs according to age. This study aims to examine the associations between PTSD and physical health conditions across four adult age categories.

METHODS

We analyzed data from the 2012 to 2013 National Epidemiologic Survey on Alcohol and Related Conditions (N = 36,309). The Alcohol Use Disorder and Associated Disabilities Interview Schedule-5 assessed past-year DSM-5 PTSD. Multiple regression analyses examined associations between PTSD (reference = no PTSD) with number and type of physical health conditions in each age category (18-34: "younger adults," 35-49: "middle-aged adults," 50-64: "young-old adults," 65+: "older adults").

RESULTS

The prevalence of nearly all physical health conditions increased according to age, whereas the prevalence of PTSD tended to decrease with age. After adjustment, PTSD was associated with a greater number of physical health conditions among all age categories (b range: 0.62-1.29). Regardless of age category, PTSD was associated with increased odds of cardiovascular and musculoskeletal conditions (AOR range: 1.54-2.34). PTSD was also associated with increased odds of gastrointestinal, hepatobiliary, endocrine/metabolic, respiratory, neurologic conditions, cancer, sleep disorders, and anemia among select age categories (AOR range: 1.70-3.31). For most physical health conditions, the largest effect sizes emerged for younger and middle-aged adults.

CONCLUSIONS

PTSD is associated with many physical health conditions across the age spectrum, particularly among younger and middle-aged adults. Results may inform targeted screening and intervention strategies to mitigate risk of physical health conditions among adults with PTSD.

Persistence of post-concussion symptoms in patients with mild traumatic brain injury and no psychiatric history in the emergency department

PURPOSE

To elucidate the predictive factors for persistent post-concussion symptoms at 1 and 3 months following minor traumatic brain injuries (mTBIs) in patients with no psychiatric history.

METHODS

This was an observational study in an academic trauma centre including adult patients with a history of mTBI and no psychiatric history. Exclusion criteria were missing the follow-up phone calls, radiologic abnormalities, simultaneous injuries and refusal to participate. Outcomes were post-concussion syndrome according to the international classification of diseases (ICD)-10 (ICD-PCS) and persistence of more than one mTBI related symptoms at 1 and 3 months post-injury.

RESULTS

From 364 enrolled patients, 16 (4.4%) developed ICD-PCS, whereas 28 (7.6%) and 8(2.1%) reported more than one symptom at one and three months, respectively. Multivariable analysis showed associations between ICD-PCS with more than one initial symptom in the emergency department (ED) and the non-motor vehicle collision (non-MVC) impact mechanism with area under curve of 0.77. The former variable was associated with the persistence of more than one post-concussion symptom at one and three months.

CONCLUSION

More than one symptom in the ED and the mechanism of injury not related to MVCs (sports, violence or fall injuries) may predict symptom persistence. Early treatment and follow-up strategies may be beneficial for vulnerable patients.

Comparison of Four Quality of Life Inventories for Patients with Traumatic Brain Injuries and Orthopedic Injuries

The value of assessing health-related quality of life (HRQoL) in traumatic brain injury (TBI) patients has been increasingly recognized in recent years. Yet, research examining generic and TBI-specific quality of life (QOL) methodologies within this population has been limited, rendering decisions to use one alternative over another difficult and based largely on conceptual grounds. The current study compared widely used generic QoL/HRQOL measures (Satisfaction With Life Scale, 36-item Short Form Survey) and newer population-specific HRQoL measures (Quality of Life after Brain Injury [QOLIBRI], Trauma-Quality of Life [TQoL]) among 77 TBI and 23 orthopedically injured trauma control patients. The QOLIBRI Cognition and Physical Problems subscales were the only HRQoL scores across the four instruments administered that differentiated between patient groups: participants with TBI reported being significantly less satisfied with their cognitive abilities and more bothered by physical problems. Analyses of the unique population-specific QOLIBRI content revealed that 12.2-31.5% of TBI patients endorsed dissatisfaction and 28.8-51.4% endorsed being bothered by items unique to the QOLIBRI. Endorsement rates for unique TQoL items ranged from 1.4-75.7%. Overall, the QOLIBRI and TQoL appear to capture important information pertinent to patients with TBI and trauma. Inclusion of these disease-specific HRQoL measures is recommended over the use of only generic measures among TBI populations.

Polydatin prevents the induction of secondary brain injury after traumatic brain injury by protecting neuronal mitochondria

Polydatin is thought to protect mitochondria in different cell types in various diseases. Mitochondrial dysfunction is a major contributing factor in secondary brain injury resulting from traumatic brain injury. To investigate the protective effect of polydatin after traumatic brain injury, a rat brain injury model of lateral fluid percussion was established to mimic traumatic brain injury insults. Rat models were intraperitoneally injected with polydatin (30 mg/kg) or the SIRT1 activator SRT1720 (20 mg/kg, as a positive control to polydatin). At 6 hours post-traumatic brain injury insults, western blot assay was used to detect the expression of SIRT1, endoplasmic reticulum stress related proteins and p38 phosphorylation in cerebral cortex on the injured side. Flow cytometry was used to analyze neuronal mitochondrial superoxide, mitochondrial membrane potential and mitochondrial permeability transition pore opened. Ultrastructural damage in neuronal mitochondria was measured by transmission electron microscopy. Our results showed that after treatment with polydatin, release of reactive oxygen species in neuronal mitochondria was markedly reduced; swelling of mitochondria was alleviated; mitochondrial membrane potential was maintained; mitochondrial permeability transition pore opened. Also endoplasmic reticulum stress related proteins were inhibited, including the activation of p-PERK, spliced XBP-1 and cleaved ATF6. SIRT1 expression and activity were increased; p38 phosphorylation and cleaved caspase-9/3 activation were inhibited. Neurological scores of treated rats were increased and the mortality was reduced compared with the rats only subjected to traumatic brain injury. These results indicated that polydatin protectrd rats from the consequences of traumatic brain injury and exerted a protective effect on neuronal mitochondria. The mechanisms may be linked to increased SIRT1 expression and activity, which inhibits the p38 phosphorylation-mediated mitochondrial apoptotic pathway. This study was approved by the Animal Care and Use Committee of the Southern Medical University, China (approval number: L2016113) on January 1, 2016.
