Callahan, M., Binder, L., O’Neil, M., Zaccari, B., Roost, M., Golshan, S., … & Storzbach, D. (2017). Sensory sensitivity
ABSTRACT: To examine factors associated with noise and light sensitivity among returning Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) Veterans with a self-reported history of mild traumatic brain injury (mTBI) due to blast exposure, we compared the self-report of noise and light sensitivity of 42 OEF/OIF Veterans diagnosed with mTBI resulting from combat blast-exposure to that of 36 blast-exposed OEF/OIF Veterans without a history of mTBI. Results suggest a statistically significant difference between Veterans with and without a history of mTBI in the experience of noise and light sensitivity, with sensory symptoms reported most frequently in the mTBI group.
Cao, J., Gaamouch, F., Meabon, J., Meeker, K., Zhu, L., Zhong, M., … & Cai, D. (2017). ApoE4-associated
ABSTRACT: The apolipoprotein E4 (ApoE4) genotype combines with traumatic brain injury (TBI) to increase the risk of developing Alzheimer's Disease (AD). However, the underlying mechanism(s) is not well-understood. We found that after exposure to repetitive blast-induced TBI, phosphoinositol biphosphate (PIP2) levels in hippocampal regions of young ApoE3 mice were elevated and associated with reduction in expression of a PIP2 degrading enzyme, synaptojanin 1 (synj1). In contrast, hippocampal PIP2 levels in ApoE4 mice did not increase after blast TBI.
Cline, M., Yumul, J., Hysa, L., Murra, D., Garwin, G., Cook, D. G., … & Cross, D. (2017). Novel application of a Radial
ABSTRACT: The use of forced-swim, rat-validated cognition tests in mouse models of traumatic brain injury (TBI) raises methodological concerns; such models are vulnerable to a number of confounding factors including impaired motor function and stress-induced non-compliance (failure to swim). This study evaluated the ability of a Radial Water Tread (RWT) maze, designed specifically for mice, that requires no swimming to distinguish mice with controlled cortical impact (CCI) induced TBI and Sham controls.
Danziger, S., Miller, L., Singh, K., Whitney, G., Peskind, E. R., Li, G., … & Smith, J. (2017). An indicator cell assay
ABSTRACT: We have established proof of principle for the Indicator Cell Assay Platform™ (iCAP™), a broadly applicable tool for blood-based diagnostics that uses specifically-selected, standardized cells as biosensors, relying on their innate ability to integrate and respond to diverse signals present in patients’ blood. To develop an assay, indicator cells are exposed in vitro to serum from case or control subjects and their global differential response patterns are used to train reliable, disease classifiers based on a small number of features. In a feasibility study, the iCAP detected pre-symptomatic disease in a murine model of amyotrophic lateral sclerosis (ALS) with 94% accuracy (p-Value = 3.81E-6) and correctly identified samples from a murine Huntington’s disease model as non-carriers of ALS.
Demidenko, M. I., Dobscha, S. K., Morasco, B. J., Meath, T. H. A., Ilgen, M. A., & Lovejoy, T. I. (2017). Suicidal ideation
ABSTRACT: Little is known about patient outcomes following discontinuation of opioid therapy, which may include suicidal ideation and suicidal self-directed violence. Five hundred-nine Veterans Health Administration (VHA) patients whose clinicians discontinued them from LTOT were selected from a national cohort of Veterans Health Administration (VHA) patients who discontinued opioids in 2012. The purpose of this study was to examine correlates of suicidal ideation and non-fatal suicidal self-directed violence in a sample of patients discontinued from long-term opioid therapy.

Durazzo, T., Meyerhoff, D. J., Yoder, K. K., & Murray, D. (2017). Cigarette smoking is associated with amplified age-related
ABSTRACT: Magnetic resonance imaging studies of cigarette smoking-related effects on human brain structure have primarily employed voxel-based morphometry, and the most consistently reported finding was smaller volumes or lower density in anterior frontal regions and the insula. Much less is known about the effects of smoking on subcortical regions. We compared smokers and non-smokers on regional subcortical volumes, and predicted that smokers demonstrate greater age-related volume loss across subcortical regions than non-smokers.

ABSTRACT: Expert guidelines recommend reducing or discontinuing long-term opioid therapy (LTOT) when risks outweigh benefits, but evidence on the effect of dose reduction on patient outcomes has not been systematically reviewed. The purpose of this study is to synthesize studies of the effectiveness of strategies to reduce or discontinue LTOT and patient outcomes after dose reduction among adults prescribed LTOT for chronic pain.

Hoggatt, K., Lehavot, K., Krenek, M., Schweizer, C., & Simpson, T. L. (2017). Prevalence of substance misuse among US
ABSTRACT: Epidemiologic data on substance misuse prevalence among US Veterans are crucial to plan for Veterans' future healthcare needs. We estimated US Veterans' age-specific, overall, and age-adjusted prevalence of substance misuse, assessed whether prevalence differed between Veterans and civilians, and examined temporal trends in prevalence.
Kruse, L., Schindler, A., Williams, R., Weber, S., & Clark, J. (2017). Maladaptive decision making in adults with a
ABSTRACT: According to recent WHO reports, alcohol remains the number one substance used and abused by adolescents, despite public health efforts to curb its use. Adolescence is a critical period of biological maturation where brain development, particularly the mesocorticolimbic dopamine system, undergoes substantial remodeling. These circuits are implicated in complex decision making, incentive learning and reinforcement during substance use and abuse. An appealing theoretical approach has been to suggest that alcohol alters the normal development of these processes to promote deficits in reinforcement learning and decision making, which together make individuals vulnerable to developing substance use disorders in adulthood. Previously we have used a preclinical model of voluntary alcohol intake in rats to show that use in adolescence promotes risky decision making in adulthood that is mirrored by selective perturbations in dopamine network dynamics.
Lehavot, K., Blosnich, J., Glass, J., & Williams, E. (2017). Alcohol use and receipt of alcohol screening and brief
ABSTRACT: Despite evidence of alcohol disparities between sexual minority and heterosexual individuals in the general population, research has not examined whether there are disparities in receipt of alcohol screening and brief intervention - together considered one of the highest prevention priorities for US adults. This study examined differences in alcohol use and receipt of alcohol screening and brief intervention across sexual minority status.
Lehavot, K., Katon, J., Simpson, T. L., & Shipherd, J. (2017). Transgender veterans’ satisfaction with care and unmet
ABSTRACT: Transgender individuals are overrepresented among Veterans. However, little is known regarding their satisfaction with Veterans Administration (VA) care and unmet health needs. This study examined transgender Veterans' satisfaction with VA medical and mental health care, prevalence of delaying care, and correlates of these outcomes.
Lehavot, K., Litz, B., Millard, S., Hamilton, A., Sadler, A., & Simpson, T. L. (2017). Study adaptation, design, and
ABSTRACT: Women Veterans are a rapidly growing population with high risk of exposure to potentially traumatizing events and PTSD diagnoses. Despite the dissemination of evidence-based treatments for PTSD in the VA, most women Veteran VA users underutilize these treatments. Web-based PTSD treatment has the potential to reach and engage women Veterans with PTSD who do not receive treatment in VA settings. Our objective is to modify and evaluate Delivery of Self Training and Education for Stressful Situations (DESTRESSS), a web-based cognitive-behavioral intervention for PTSD, to target PTSD symptoms among women Veterans.

Lovejoy, T. I., Morasco, B. J., Demidenko, M. I., Meath, T. H. A., Frank, J. W., & Dobscha, S. K. (2017). Reasons for
ABSTRACT: Several factors may accelerate opioid discontinuation rates, including lack of information about the long-term effectiveness of opioids for chronic pain, heightened awareness about opioid-related adverse events, closer monitoring of patients for opioid-related aberrant behaviors, and greater restrictions around opioid prescribing. Rates of discontinuation may be most pronounced in patients deemed to be at "high risk." The purpose of this study was to compare reasons for discontinuation of long-term opioid therapy between patients with and without Substance Use Disorder diagnoses. This retrospective cohort study assembled a cohort of Veterans Health Administration patients prescribed opioid therapy for at least 12 consecutive months...

ABSTRACT: To examine the potential moderating effects of mental health symptoms on the efficacy of compensatory cognitive training (CCT) for Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn veterans with a history of mild traumatic brain injury (mTBI). DESIGN: Secondary analysis of a randomized controlled trial of CCT. Posttraumatic stress disorder, depression, and substance dependence symptom severity were examined as potential moderators of CCT efficacy for subjective cognitive complaints, use of cognitive strategies, and objective neurocognitive performance.
Pottiez, G., Yang, L., Stewart, T., Song, N., Aro, P., Galasko, D., … & Zhang, J. (2017). Mass-spectrometry-based method
ABSTRACT: Alzheimer's disease (AD), the most common form of dementia, afflicts about 50 million people worldwide. Currently, AD diagnosis is primarily based on psychological evaluation and can only be confirmed post-mortem. Reliable and objective biomarkers for prognosis and diagnosis have been sought for years. Together, tau and amyloid β 1-42 (Aβ42) in cerebrospinal fluid (CSF) have been shown to provide good diagnostic sensitivity and specificity. Additionally, phosphorylated forms of tau, such as tau pS181, have also shown promising results. However, the measurement of such markers currently relies on antibody-based immunoassays that have shown variability, leading to discrepant results across laboratories.

ABSTRACT: Stress-induced anxiety is a risk factor for relapse to alcohol drinking. The aim of this study was to test the hypothesis that the central nervous system (CNS)-active α1-adrenergic receptor antagonist, prazosin, would block the stress-induced increase in anxiety that occurs during alcohol deprivations.
