RESUMEN
OBJECTIVE: This study surveyed the use of community-based resource facilitation (RF) services by ethnic minority survivors of traumatic brain injury (TBI) living in the Midwestern United States. METHOD: Past records of RF use by survivors of TBI were reviewed. Demographics and patterns of RF use across 3 ethnic groups were documented. Reported barriers to community integration related to ethnic identity were identified using Chi-square test of independence. RESULTS: Ethnic minority survivors were less likely to use RF services than white survivors. Caucasian women and men utilized RF services at similar rates, whereas more African American men and Latina women used RF services. Caucasians received information about RF from a greater variety of sources than ethnic minority survivors. Ethnic identity was significantly associated with greater reported needs for TBI awareness. CONCLUSIONS: A pattern of differential RF use by survivors from ethnic minority groups was noted, suggesting potential socio-cultural influences on help-seeking behavior after TBI. These factors should be considered to develop more accessible and equitable strategies of RF service referral and support. Future investigations of cultural perspectives of TBI and injury-related services may improve understanding of the likelihood and necessity of community-based RF service use by diverse populations.

OBJECTIVE: Metacognition and quality of life (QoL) are both adversely affected by traumatic brain injury (TBI), but the relation between them is not fully understood. As such, the purpose of this study was to determine the degree to which metacognitive accuracy predicts QoL in individuals with TBI. METHODS: Eighteen participants with moderate-to-severe TBI completed a stimulus-response task requiring the discrimination of emotions depicted in pictures of faces and then provided a retrospective confidence judgment after each response. Metacognitive accuracy was calculated using participants' response accuracy and confidence judgment accuracy. Participants also completed the Quality of Life After Brain Injury (QOLIBRI) questionnaire to assess QoL in various areas of functioning. RESULTS: Performance of a linear regression analysis revealed that higher metacognitive accuracy significantly predicted lower overall QoL. Additionally, higher metacognitive accuracy significantly predicted lower QoL related to cognition and physical limitations. CONCLUSION: The study results provide evidence of an inverse relation between metacognitive performance and QoL following TBI. Metacognitive changes associated with TBI and their relation to QoL have several clinical implications for TBI rehabilitation.

This study explores the perspectives of intimate partner violence (IPV) survivors and staff of brain injury (BI) screening, and the neuropsychological evaluation (NPE) process. We gathered qualitative data from 17 participants - 10 IPV survivors, at risk for a BI, who had received BI screening and a NPE and a total of 7 staff in IPV-serving organizations. Interviews were recorded, transcribed verbatim and analysed for key themes using thematic analysis. Survivors were over 18 years of age; the majority were between 19 and 45 years old, unemployed, unmarried, and had children. Survivors were angry, scared, and embarrassed to learn that they might have an IPV-related BI. They were thankful to have an explanation for some of their cognitive symptoms, which disrupted their daily activities, social relationships, and overall quality of life. Staff were pleased to be able to provide valuable information to their clients that could have a positive impact on their wellbeing. Overall, screening for a BI and participation in the NPE were well tolerated by IPV survivors with a possible BI. Inclusion of the perspectives of IPV survivors and support staff is an essential first step to better understanding their needs so interventions can be developed to aid their recovery.
RESUMEN
OBJECTIVES: To examine neuropsychological functioning as a predictor of psychosocial adjustment difficulties at discharge from a postacute residential rehabilitation facility for traumatic brain injury (TBI) and depression as a potential mediator. METHODS: A retrospective record review was conducted of 172 adults who received rehabilitation services for TBI. Individuals completed a full battery of neuropsychological tests, depression assessment, and functional assessments at admission. Functional assessments were also obtained at discharge. RESULTS: A two-phase structural equation model analysis was performed. The first phase specified a good fitting model of a cognitive functioning (CF) latent construct with four indicators of cognitive domains measuring verbal fluency, cognitive flexibility, verbal learning, and working memory. Worse CF was associated with greater psychosocial adjustment impairment at discharge, but not related to depression. Psychosocial adjustment impairment at admission was positively associated with depression when controlling for CF, however depression did not predict psychosocial adjustment at discharge. Thus, depression was not found to be a significant mediator of psychosocial adjustment impairment at discharge. CONCLUSIONS: Results provide support for neuropsychological functioning at the start of postacute rehabilitation for TBI as an important predictor of psychosocial functioning difficulties that remain upon discharge and highlights the need to examine mechanisms beyond depression.

OBJECTIVE: A high prevalence of depression exists in specific sub-samples of survivors of brain injury (BI) sustained from intimate partner violence (IPV). However, the experience of depression by survivors of IPV-related BI from general civilian populations remains unclear. This study documents the symptom profile of depression reported by individuals who screened positive for sustaining an IPV-related BI. METHODS: 36 individuals who screened positive for possible IPV-related BI completed the Beck Depression Inventory-2nd Edition (BDI-II). Subscales characterizing the nature of the symptoms were created. Frequency and descriptive statistics were calculated for item responses on the BDI-II. Participants were also assigned to high or low symptom severity groups to examine between-group differences. RESULTS: Participants endorsed experiencing somatic symptoms more severely than self-evaluative and affective symptoms. Additionally, self-evaluative and cognitive symptoms correlated with total BDI-II scores for the high symptom severity group but not for the low symptom severity group. CONCLUSIONS: The findings highlight somatic symptoms of depression, in particular as a common experience among survivors of IPV-related BI. Further, self-evaluative and cognitive symptoms may be more sensitive in detecting depression after IPV-related BI. These results may aid in the development of guidelines to better diagnose and treat depression in IPV-related BI.

OBJECTIVE: Traumatic brain injury (TBI) may result in metacognitive impairments. Enhancing memory in healthy adults can improve metacognitive accuracy, but it is unclear whether such interventions apply to individuals with TBI. This study examined the effects of manipulating target memory experiences on metacognitive accuracy in TBI. PARTICIPANTS: Fourteen community-dwelling adults with TBI and 17 healthy controls. MAIN MEASURES: Memory was manipulated through performance feedback (monetary, nonmonetary, or none) presented during a word-pair learning task. Recognition of the word pairs was assessed, and metacognition was evaluated by retrospective confidence judgments. RESULTS: Both groups demonstrated greater recognition performance for items learned with nonmonetary feedback. Healthy individuals demonstrated improved metacognitive accuracy for items learned with nonmonetary feedback, but this effect was not seen in individuals with TBI. A notable (but statistically nonsignificant) effect was observed whereby adults with TBI overestimated performance for items learned with monetary feedback compared with other feedback conditions. CONCLUSION: Provision of feedback during learning enhances recognition performance. However, target memory experiences may be utilized differently after injury to facilitate confidence judgments. In addition, the type of feedback provided may have different effects on metacognitive accuracy. These results have implications for rehabilitative efforts in the area of memory and metacognition after injury.

BACKGROUND: Neuropsychiatric symptoms are common following traumatic brain injury (TBI), but their etiological onset remains unclear. Mental health research implicates neuroinflammation in the development of psychiatric disorders. The presence of neuroinflammatory responses after TBI thus prompts an investigation of their involvement in the emergence of neuropsychiatric disorders postinjury. OBJECTIVE: Review the literature surrounding the role of neuroinflammation and immune response post-TBI in the development of neuropsychiatric disorders. METHODS: A search of scientific databases was conducted for original, empirical studies in human subjects. Key words such as "neuroinflammation," "TBI," and "depression" were used to identify psychopathology as an outcome TBI and the relation to neuroinflammatory response. RESULTS: Study results provide evidence of neuroinflammation mediated post-TBI neuropsychiatric disorders including anxiety, trauma/stress, and depression. Inflammatory processes and stress response dysregulation can lead to secondary cell damage, which promote the development and maintenance of neuropsychiatric disorders postinjury. CONCLUSION: This review identifies both theoretical and empirical support for neuroinflammatory response as feasible mechanisms underlying neuropsychiatric disorders after TBI. Further understanding of these processes in this context has significant clinical implications for guiding the development of novel treatments to reduce psychiatric symptoms postinjury. Future directions to address current limitations in the literature are discussed.

OBJECTIVE: To document the process by which metacognitive judgments ("online" monitoring of one's own cognitive performance during task completion) are made after traumatic brain injury (TBI). PARTICIPANTS: Sixteen community-dwelling adults with moderate to severe TBI and 16 matched healthy controls. DESIGN: Prospective, cross-sectional design. MEASURES: Metacognitive retrospective confidence judgments and reaction times were collected as participants performed a metamemory task. RESULTS: Adults with TBI did not differ from healthy peers in metacognitive accuracy; however, they took significantly longer to make retrospective confidence judgments. Retrospective confidence judgment reaction times were not consistently correlated to measures of processing speed in either sample. CONCLUSIONS: Adults with TBI engage in different postdecisional processes to make metacognitive judgments compared with healthy controls. Findings suggest that reaction times may be an important dimension of metacognition to assess clinically after TBI.

Background and Objective: Changes in cerebral white matter organization have been documented in acute phases of recovery from traumatic brain injury (TBI). However, little is known about reorganization processes in more chronic stages of recovery. The current study identified changes in white matter organization in chronic cases of TBI, and determined the relationship between structural changes and cognitive functioning. Methods: 15 adults with moderate to severe TBI and eight healthy controls completed neuropsychological testing and diffusion tensor imaging (DTI) scanning. Participants returned 3 years from the initial session to complete identical neuropsychological tests and scans. Results: Adults with TBI were found to have significantly reduced fractional anisotropy (FA), a metric of white matter organization, compared to healthy participants at baseline and also at 3-year follow-up. Within the sample of adults with TBI, increases in FA were observed over time. Importantly, increases in FA in the TBI sample were also correlated with improvements in cognitive performance. Conclusions: This study provides evidence of a dynamic process of white matter change occurring beyond the initial phases of recovery after moderate to severe TBI. The observed relationship between structural reorganization and changes in cognitive performance has implications for rehabilitation potential in more chronic phases of recovery.

OBJECTIVE: To explore how individual differences affect rehabilitation outcomes by specifically investigating whether working memory capacity (WMC) can be used as a cognitive marker to identify who will and will not improve from memory rehabilitation. DESIGN: Post hoc analysis of a randomized controlled clinical trial designed to treat learning and memory impairment after traumatic brain injury (TBI): 2 × 2 between-subjects quasiexperimental design (2 [group: treatment vs control] × 2 [WMC: high vs low]). SETTING: Nonprofit medical rehabilitation research center. PARTICIPANTS: Participants (N=65) with moderate to severe TBI with pre- and posttreatment data. INTERVENTIONS: The treatment group completed 10 cognitive rehabilitation sessions in which subjects were taught a memory strategy focusing on learning to use context and imagery to remember information. The placebo control group engaged in active therapy sessions that did not involve learning the memory strategy. MAIN OUTCOME MEASURE: Long-term memory percent retention change scores for an unorganized list of words from the California Verbal Learning Test-II. RESULTS: Group and WMC interacted (P=.008, ηp(2)=.12). High WMC participants showed a benefit from treatment compared with low WMC participants. Individual differences in WMC accounted for 45% of the variance in whether participants with TBI in the treatment group benefited from applying the compensatory treatment strategy to learn unorganized information. CONCLUSIONS: Individuals with higher WMC showed a significantly greater rehabilitation benefit when applying the compensatory strategy to learn unorganized information. WMC is a useful cognitive marker for identifying participants with TBI who respond to memory rehabilitation with the modified Story Memory Technique.

OBJECTIVE: As measurements of subjective fatigue after traumatic brain injury (TBI) rely on self-assessment, deficits in self-awareness after TBI may distort subjective fatigue reports. This study investigates awareness of subjective fatigue after TBI using self- and informant reports. PARTICIPANTS: Fourteen adults with moderate to severe TBI and 7 healthy controls (HCs). MEASURES: Modified Fatigue Impact Scale (MFIS) and battery of cognitive and emotional tests. Informants completed an "other-report," rating their perception of participant's fatigue. Subjective fatigue awareness was defined as discrepancy between self- and other-MFIS scores. RESULTS: Adults with TBI showed greater discrepancies between self- and other-MFIS scores than did HCs. Negative relations were found between fatigue awareness and symptoms of depression, but there were no relationships between fatigue awareness and cognitive performance. CONCLUSIONS: Results indicate that adults with TBI have poorer awareness of subjective fatigue than HCs. Correlations between subjective fatigue awareness and depression support existing literature implicating strong emotional components in the experience of subjective fatigue postinjury. Findings suggest cautious interpretation of subjective fatigue, as responses may not reflect fatigue symptoms exclusively.

Despite a high prevalence of injection drug use (IDU) in Puerto Rico, little is known about how it affects neuropsychological functioning in this population. Investigations of intra-individual variability (IIV) have alluded to its utility as a potential indicator of neural decline. The purpose of this study was to characterize IIV among Hispanic residents of Puerto Rico who engage in IDU. Injectors and non-injectors completed the Neuropsí Atención y Memoria battery. Measures of IIV were calculated for the overall test battery (OTB), the three battery indices, and three domains of attention, memory, and executive functioning. The injector group showed significantly greater IIV than the non-injector group on all measures (OTB, indices, and individual domains). Additionally, injectors showed significantly higher IIV in the domain of executive functioning compared to other cognitive domains and battery indices. In contrast, non-injectors did not show any significant within-group differences on any IIV measures. The higher performance variability observed in the IDU group suggests a negative influence of IDU on cognition, with executive functioning being more susceptible to these effects. These findings support the need for continued investigations into the clinical application of IIV for diagnostic and prognostic purposes in the Hispanic IDU population.
RESUMEN
Survivors of intimate partner violence (IPV) are at heightened risk of sustaining a brain injury (BI). Problematically, a high overlap between BI and trauma symptoms leads to difficulties in identifying when an IPV-related BI has occurred. This paper investigated differences in symptom reports between survivors with (n = 95) and without (n = 42) probable IPV-related BI. Chi-squared analyses isolated a constellation of symptoms found to be specifically associated with BI status. These symptomatic markers may assist professionals in discerning BI from other comorbid conditions present in IPV, and thus help survivors access BI-specific treatments and resources.
RESUMEN
Antiretroviral therapy has been effective in suppressing HIV viral load and enabling people living with HIV to experience longer, more conventional lives. However, as people living with HIV are living longer, they are developing aging-related diseases prematurely and are more susceptible to comorbidities that have been linked to chronic inflammation. Coincident with HIV infection and aging, drug abuse has also been independently associated with gut dysbiosis, microbial translocation, and inflammation. Here, we hypothesized that injection drug use would exacerbate HIV-induced immune activation and inflammation, thereby intensifying immune dysfunction. We recruited 50 individuals not using injection drugs (36/50 HIV+) and 47 people who inject drugs (PWID, 12/47 HIV+). All but 3 of the HIV+ subjects were on antiretroviral therapy. Plasma immune profiles were characterized by immunoproteomics, and cellular immunophenotypes were assessed using mass cytometry. The immune profiles of HIV+/PWID-, HIV-/PWID+, and HIV+/PWID+ were each significantly different from controls; however, few differences between these groups were detected, and only 3 inflammatory mediators and 2 immune cell populations demonstrated a combinatorial effect of injection drug use and HIV infection. In conclusion, a comprehensive analysis of inflammatory mediators and cell immunophenotypes revealed remarkably similar patterns of immune dysfunction in HIV-infected individuals and in people who inject drugs with and without HIV-1 infection.

Previous studies of the BOLD response in the injured brain have revealed neural recruitment relative to controls during working memory tasks in several brain regions, most consistently the right prefrontal cortex and anterior cingulate cortices. We previously proposed that the recruitment observed in this literature represents auxiliary support resources, and that recruitment of PFC is not abnormal or injury specific and should reduce as novelty and challenge decrease. The current study directly tests this hypothesis in the context of practice of a working memory task. It was hypothesized that individuals with brain injury would demonstrate recruitment of previously indicated regions, behavioral improvement following task practice, and a reduction in the BOLD signal in recruited regions after practice. Individuals with traumatic brain injury and healthy controls performed the n-back during fMRI acquisition, practiced each task out of the scanner, and returned to the scanner for additional fMRI n-back acquisition. Statistical parametric maps demonstrated a number of regions of recruitment in the 1-back in individuals with brain injury and a number of corresponding regions of reduced activation in individuals with brain injury following practice in both the 1-back and 2-back. Regions of interest demonstrated reduced activation following practice, including the anterior cingulate and right prefrontal cortices. Individuals with brain injury demonstrated modest behavioral improvements following practice. These findings suggest that neural recruitment in brain injury does not represent reorganization but a natural extension of latent mechanisms that engage transiently and are contingent upon cerebral challenge.

The ability to appraise one's own ability has been found to have an important role in the recovery and quality of life of clinical populations. Examinee and task variables have been found to influence metacognition in healthy students; however the effect of these variables on the metacognitive accuracy of adults with neurological insult, such as traumatic brain injury (TBI), remains unknown. Twenty-two adults with moderate and severe TBI and a matched sample of healthy adults participated in this study examining the influence of item sequencing on metacognitive functioning. Retrospective confidence judgments were collected while participants completed a modified version of the Matrix Reasoning subtest. Significant influence of item sequence order was found, revealing better metacognitive abilities and performance when participants completed tasks where item difficulty progressed in order from easy to difficult. We interpret these findings to suggest that the sequencing of item difficulty offers "anchors" for gauging and adjusting to task demands.

Background: Respondent Driven Sampling (RDS) is an effective sampling strategy to recruit hard-to-reach populations but the impact of the COVID-19 pandemic on the use of this strategy in the collection of data involving human subjects, particularly among marginalized and vulnerable populations, is not known. Based on an ongoing study using RDS to recruit and study the interactions between HIV infection, injection drug use, and the microbiome in Puerto Rico, this paper explores the effectiveness of RDS during the pandemic and provided potential strategies that could improve recruitment and data collection. Results: RDS was employed to evaluate its effectiveness in recruiting a group of people who inject drugs (PWID) and controls (N = 127) into a study in the midst of the COVID-19 pandemic. The participants were distributed among three subsets: 15 were HIV+ and PWID, 58 were HIV- PWID, and 54 were HIV+ and not PWID. Findings: Results show that recruitment through peer networks using RDS was possible across all sub-groups. Yet, while those in the HIV+ PWID sub-group managed to recruit from other-sub groups of HIV- PWID and HIV+, this occurred at a lower frequency. Conclusion: Despite the barriers introduced by COVID-19, it is clear that even in this environment, RDS continues to play a powerful role in recruiting hard-to-reach populations. Yet, more attention should be paid at how future pandemics, natural disasters, and other big events might affect RDS recruitment of vulnerable and hard-to-reach populations.
RESUMEN
The ability to engage in self-reflective processes is a capacity that may be disrupted after neurological compromise; research to date has demonstrated that patients with traumatic brain injury (TBI) show reduced awareness of their deficits and functional ability compared to caretaker or clinician reports. Assessment of awareness of deficit, however, has been limited by the use of subjective measures (without comparison to actual performance) that are susceptible to report bias. This study used concurrent measurements from cognitive testing and confidence judgments about performance to investigate in-the-moment metacognitive experiences after moderate and severe traumatic brain injury. Deficits in metacognitive accuracy were found in adults with TBI for some but not all indices, suggesting that metacognition may not be a unitary construct. Findings also revealed that not all indices of executive functioning reliably predict metacognitive ability.

The study examined rates of possible brain injury among survivors of intimate partner violence. Of the 171 women screened, 91% indicated they had been hit in the head or strangled, and 31% reported it happened more than six times in their life. Only 35% of women who were hit in the head or strangled received medical treatment, and 64% reported losing consciousness or experienced a period of being dazed and confused. Organizations serving intimate partner violence survivors should routinely screen survivors for brain injury so they can obtain timely referrals for neurorehabilitation services to improve their quality of life.

Intimate partner violence includes psychological aggression, physical violence, sexual violence, and stalking from a current or former intimate partner. Past research suggests that exposure to intimate partner violence can impact cognitive and psychological functioning, as well as neurological outcomes. These seem to be compounded in those who suffer a brain injury as a result of trauma to the head, neck or body due to physical and/or sexual violence. However, our understanding of the neurobehavioral and neurobiological effects of head trauma in this population is limited due to factors including difficulty in accessing/recruiting participants, heterogeneity of samples, and premorbid and comorbid factors that impact outcomes. Thus, the goal of the Enhancing NeuroImaging Genetics through Meta-Analysis (ENIGMA) Consortium Intimate Partner Violence Working Group is to develop a global collaboration that includes researchers, clinicians, and other key community stakeholders. Participation in the working group can include collecting harmonized data, providing data for meta- and mega-analysis across sites, or stakeholder insight on key clinical research questions, promoting safety, participant recruitment and referral to support services. Further, to facilitate the mega-analysis of data across sites within the working group, we provide suggestions for behavioral surveys, cognitive tests, neuroimaging parameters, and genetics that could be used by investigators in the early stages of study design. We anticipate that the harmonization of measures across sites within the working group prior to data collection could increase the statistical power in characterizing how intimate partner violence-related head trauma impacts long-term physical, cognitive, and psychological health.
