Abstract
Introduction The relation between traumatic brain injury (TBI), its acute and chronic symptoms, and the potential for remote neurodegenerative disease is a priority for military research. Structural and functional connectivity (FC) of the basal ganglia, involved in motor tasks such as walking, are altered in some samples of Service Members and Veterans with TBI, but any behavioral implications are unclear and could further depend on the context in which the TBI occurred. Methods In this study, FC from caudate and pallidum seeds was measured in Service Members and Veterans with a history of mild TBI that occurred during combat deployment, Service Members and Veterans whose mild TBI occurred outside of deployment, and Service Members and Veterans who had no lifetime history of TBI. Results FC patterns differed for the two contextual types of mild TBI. Service Members and Veterans with deployment-related mild TBI demonstrated increased FC between the right caudate and lateral occipital regions relative to both the non-deployment mild TBI and TBI-negative groups. When evaluating the association between FC from the caudate and gait, the non-deployment mild TBI group showed a significant positive relationship between walking time and FC with the frontal pole, implicated in navigational planning, whereas the deployment-related mild TBI group trended towards a greater negative association between walking time and FC within the occipital lobes, associated with visuo-spatial processing during navigation. Discussion These findings have implications for elucidating subtle motor disruption in Service Members and Veterans with deployment-related mild TBI. Possible implications for future walking performance are discussed.

Abstract
OBJECTIVE Working memory (WM) function requires attentional focus and resisting distracting stimuli (i.e., resistance to attentional capture [RAC]). People with histories of mild traumatic brain injury (mTBI) or posttraumatic stress (PTSD) often report difficulties with WM and attention. To better understand the relationship between these two executive functions, we collected neuropsychological and electrophysiological data from a sample of individuals with PTSD and/or mTBI. METHODS We characterized WM function in 128 US military veterans (61 controls, 22 PTSD, 24 mTBI, 21 PTSD and mTBI) using the WAIS-IV Digit Span (DS). To examine RAC we completed electroencephalography recordings during an Erikson Flanker task. Flanker task trials were coded as either Congruent (flanker stimuli same direction as target) or Incongruent (opposite direction). We characterized the P1 event-related potential which has shown sensitivity to RAC. RESULTS There was an interaction between Flanker Type and DS such that poorer WM performance was related to greater difficulties on Incongruent trials. Analyses of P1 amplitude revealed an interaction between DS scores and P1 amplitude with better DS performance related to larger P1 amplitudes in trials with Incongruent compared to Congruent flankers. There was also an interaction between PTSD and Flanker Type such that PTSD was associated with larger P1 amplitudes for Incongruent than Congruent flanker trials. CONCLUSIONS Our observations suggest greater RAC aids in WM function, and is also associated with early perception-related brain responses (i.e., P1) that modulate with demands to resist distracting stimuli. Our results also suggest PTSD is related to electrophysiological functions tied to RAC.

Abstract
Investigators in neuroscience have turned to Big Data to address replication and reliability issues by increasing sample sizes, statistical power, and representativeness of data. These efforts unveil new questions about integrating data arising from distinct sources and instruments. We focus on the most frequently assessed cognitive domain - memory testing - and demonstrate a process for reliable data harmonization across three common measures. We aggregated global raw data from 53 studies totaling N = 10,505 individuals. A mega-analysis was conducted using empirical bayes harmonization to remove site effects, followed by linear models adjusting for common covariates. A continuous item response theory (IRT) model estimated each individual's latent verbal learning ability while accounting for item difficulties. Harmonization significantly reduced inter-site variance while preserving covariate effects, and our conversion tool is freely available online. This demonstrates that large-scale data sharing and harmonization initiatives can address reproducibility and integration challenges across the behavioral sciences.

Abstract
Results of neuroimaging datasets aggregated from multiple sites may be biased by site-specific profiles in participants' demographic and clinical characteristics, as well as MRI acquisition protocols and scanning platforms. We compared the impact of four different harmonization methods on results obtained from analyses of cortical thickness data: (1) linear mixed-effects model (LME) that models site-specific random intercepts (LMEINT), (2) LME that models both site-specific random intercepts and age-related random slopes (LMEINT+SLP), (3) ComBat, and (4) ComBat with a generalized additive model (ComBat-GAM). Our test case for comparing harmonization methods was cortical thickness data aggregated from 29 sites, which included 1,340 cases with posttraumatic stress disorder (PTSD) (6.2-81.8 years old) and 2,057 trauma-exposed controls without PTSD (6.3-85.2 years old). We found that, compared to the other data harmonization methods, data processed with ComBat-GAM was more sensitive to the detection of significant case-control differences (Χ2(3) = 63.704, p < 0.001) as well as case-control differences in age-related cortical thinning (Χ2(3) = 12.082, p = 0.007). Both ComBat and ComBat-GAM outperformed LME methods in detecting sex differences (Χ2(3) = 9.114, p = 0.028) in regional cortical thickness. ComBat-GAM also led to stronger estimates of age-related declines in cortical thickness (corrected p-values < 0.001), stronger estimates of case-related cortical thickness reduction (corrected p-values < 0.001), weaker estimates of age-related declines in cortical thickness in cases than controls (corrected p-values < 0.001), stronger estimates of cortical thickness reduction in females than males (corrected p-values < 0.001), and stronger estimates of cortical thickness reduction in females relative to males in cases than controls (corrected p-values < 0.001). Our results support the use of ComBat-GAM to minimize confounds and increase statistical power when harmonizing data with non-linear effects, and the use of either ComBat or ComBat-GAM for harmonizing data with linear effects.

Abstract
OBJECTIVE To determine if history of mild traumatic brain injury (mTBI) is associated with advanced or accelerated brain aging among the United States (US) military Service Members and Veterans. METHODS Eight hundred and twenty-two participants (mean age = 40.4 years, 714 male/108 female) underwent MRI sessions at eight sites across the US. Two hundred and one participants completed a follow-up scan between five months and four years later. Predicted brain ages were calculated using T1-weighted MRIs and then compared with chronological ages to generate an Age Deviation Score for cross-sectional analyses and an Interval Deviation Score for longitudinal analyses. Participants also completed a neuropsychological battery, including measures of both cognitive functioning and psychological health. RESULT In cross-sectional analyses, males with a history of deployment-related mTBI showed advanced brain age compared to those without (t(884) = 2.1, p = .038), while this association was not significant in females. In follow-up analyses of the male participants, severity of posttraumatic stress disorder (PTSD), depression symptoms, and alcohol misuse were also associated with advanced brain age. CONCLUSION History of deployment-related mTBI, severity of PTSD and depression symptoms, and alcohol misuse are associated with advanced brain aging in male US military Service Members and Veterans.

Abstract
Psychological resilience as a longitudinal process is highly relevant for understanding the functioning outcomes of military populations. Here, we review the extant literature on resilience among military service members, focusing on National Guard Soldiers. Our specific project (Advancing Research on Mechanisms of Resilience, "ARMOR") aims to develop a comprehensive model of resilience using a multilevel perspective. We report results from our prospective pilot study (n = 103) conducted in preparation for our large-scale longitudinal cohort study of Basic Combat Training (BCT) and its impact on military recruits' wellbeing. Results support feasibility of the larger study, evidence for a new measure of BCT stressor exposure, and demonstrate preliminary associations with BCT-related stressors and longitudinal changes in adaptive functioning. Future directions for our larger study will utilize data from survey responses, structured clinical interviews, neurobehavioral tasks, and neurobiological measures (functional and structural MRI and electroencephalography [EEG]) to examine individual differences in self-regulation as a predictor of resilience-related processes. ARMOR is well positioned to elucidate mechanisms that could be targeted for promoting wellbeing, preventing psychopathology, and facilitating long-term recovery.

Abstract
Abstract
Introduction
Nightmares are a common problem affecting 2-8% of the general population with the prevalence of comorbid nightmares in those with post-traumatic stress disorder (PTSD) being significantly higher at 72%. The negative sequelae of nightmares are myriad including impaired quality of life, sleep deprivation, insomnia, daytime sleepiness, fatigue, and suicidal ideation. This study investigated a novel approach for the treatment of nightmare disorder in military veterans.
Methods
All participants in this study were veterans receiving care at the Minneapolis Veterans Affairs Health Care System (VAHCS), diagnosed with PTSD, and had self-reported nightmares. At the baseline assessment, eligible participants were given a digital smartwatch preloaded with an application designed to arouse but not awaken the user out of the nightmare. Paired t-test analysis was used to compare the participants’ baseline and follow-up responses.
Results
A significant decrease in participant Pittsburgh Sleep Quality Index (PSQI) scores (13.6 to 7.4, p < 0.001), PTSD Checklist for DSM-5 (PCL-5) scores (45.8 to 25.1, p < 0.0025) and Patient Health Questionnaire (PHQ-9) scores (12.2 to 6.1, p < 0.002) was observed over the sixty day trial. All 9 participants experienced a decrease in the Epworth Sleepiness Scale (ESS) upon completion of the trial, with an average decrease of -2.5 ± 1.4.
Conclusion
These results demonstrate that a novel digital therapeutic smartwatch application is effective in improving sleep quality, reducing the burden associated with PTSD symptoms, and lowering depressive symptoms in those with nightmare disorder within an open label study. These results have initiated further investigation into efficacy of digital therapeutic smartwatch applications in nightmare intervention and improved sleep quality.

Abstract
INTRODUCTION One hypothesis that unifies the diversity of symptoms associated with schizophrenia involves the disruption of connectivity between brain regions. As white matter provides rapid and efficient communication between brain regions, this study was initiated to assess the early disruption of white matter pathways in children and adolescent with schizophrenia. MATERIALS AND METHODS Diffusion tensor images were acquired on 14 children and adolescents with schizophrenia, one subject with schizoaffective disorder, and 15 age and gender matched controls. The DTI images were acquired in twelve directions on a 3 T Siemens Trio scanner. The images were transformed into fractional anisotropy and mean diffusivity maps and a group analysis was performed using SPM2. RESULTS Children and adolescent patients with schizophrenia demonstrated a significant decrease in FA and associated increase in AD in the left posterior hippocampus (p<0.001, Bonferroni corrected on the cluster-level). These diffusion differences were not statistically significant when IQ was used as a covariate in the analysis. DISCUSSION These findings suggest hippocampal white matter abnormalities that present early in the development of schizophrenia. The lack of significant differences when IQ is used as a covariate suggests that this hippocampal region is associated with cognitive changes associated with schizophrenia.

Abstract
We report a case of recurrent listeriosis for which molecular subtyping by automated ribotyping and pulsed-field gel electrophoresis confirmed either relapse of infection or reinfection due to a common source almost 9 months after initial infection due to a unique Listeria monocytogenes strain in a patient with colorectal cancer. This case report illustrates the potential use of molecular subtyping to further understand the pathogenesis and epidemiology of listeriosis and the potential for relapse of Listeria infections in humans.

Abstract
After coronary occlusion, myocardium originally supplied by the occluded vessel ultimately separates into infarct and surviving muscle. To clarify this process, evolution of collateral blood flow to infarct and to surviving myocardium was retrospectively analyzed after permanent left anterior descending occlusion in 24 closed chest dogs. Microspheres were injected before occlusion and 5 and 20 minutes and 4 hours after occlusion. Ten minutes after occlusion, dogs received either verapamil, 0.4 mg/kg, followed by 0.6 mg/kg per hour for 6 hours (n = 10) or equivalent saline solution (n = 14). These dogs were sacrificed 3 days later, the distribution of the occluded artery was defined by dye perfusion and infarcted myocardium was determined by triphenyltetrazolium staining of heart slices. Surviving muscle within the distribution of the occluded artery was divided into medial regions adjacent to the infarct (medial adjacent) and remote from the infarct (medial remote) and lateral regions adjacent to infarct (lateral adjacent) and remote from the infarct (lateral remote). In both control and verapamil groups, collateral flows in all regions increased significantly by 140 to 400% over 4 hours. However, the relative magnitude of collateral flow to different regions showed a consistent order: infarct less than medial adjacent less than medial remote less than lateral remote. There were no significant differences in regionally matched flows or size of infarction between control and verapamil-treated groups. Collateral perfusion begins to show distinctive patterns of change in infarct and surviving muscle very soon after coronary occlusion. Collateral flow within subdivisions of the occluded coronary artery bed increases as distance from the infarct increases, with lateral segments having higher flows than medial segments. This relation persists during the first 4 hours after occlusion. In this study, verapamil neither increased collateral flow to the occluded bed nor altered minimal flow requirements for myocardial survival.
