Background: Post-September 11, 2001 combat veterans represent a growing cohort of patients with unique mental health needs, particularly around post-traumatic stress disorder (PTSD) and traumatic brain injury (TBI). The United States (US) remains engaged in conflicts around the globe, so this patient cohort will continue to grow in number. With around 40% of American combat veterans from Iraq and Afghanistan seeking mental health care outside of the Veterans Affairs, understanding the psychiatric needs of the post-September 11 combat veteran is an important goal for all psychiatrists.

Objective: The aim of this study was to review the safety and efficacy of aripiprazole as monotherapy and adjunct therapy for the treatment of post-traumatic stress disorder (PTSD).

Methods: A search of both MEDLINE (1956 to May 2017) and EMBASE (1957 to May 2017) was conducted using the terms "aripiprazole" and "post-traumatic stress disorder," "posttraumatic stress disorder," or "PTSD." Studies evaluating the primary endpoint of PTSD in patients taking aripiprazole as monotherapy or adjunct therapy were analyzed for relevance.

Objective: This study assessed whether adding telephone care management to usual outpatient mental health care improved treatment attendance, medication compliance, and clinical outcomes of veterans with posttraumatic stress disorder (PTSD).

Methods: In a multisite randomized controlled trial, 358 veterans were assigned to either usual outpatient mental health treatment (N=165) or usual care plus twice-a-month telephone care management (TCM) and support in the first three months of treatment (N=193). Treatment utilization and medication refills were determined from U.

Underwater blasts propagate further and injure more readily than equivalent air blasts. Development of effective personal protection and countermeasures, however, requires knowledge of the currently unknown human tolerance to underwater blast. Current guidelines for prevention of underwater blast injury are not based on any organized injury risk assessment, human data or experimental data.

Many individuals with post-traumatic stress disorder (PTSD) experience persistent symptoms despite pharmacological treatment with antidepressants. Several open-label monotherapy and adjunctive studies have suggested that aripiprazole (a second-generation antipsychotic) may have clinical utility in PTSD. However, there have been no randomized placebo-controlled trials of aripiprazole use for PTSD.

Classifying behavior patterns in mouse models of neurological, psychiatric and neurodevelopmental disorders is critical for understanding disease causality and treatment. However, complete characterization of behavior is time-intensive, prone to subjective scoring, and often requires specialized equipment. Although several reports describe automated home-cage monitoring and individual task scoring methods, we report the first open source, comprehensive toolbox for automating the scoring of several common behavior tasks used by the neuroscience community.

Military deployments to Afghanistan and Iraq have been associated with elevated prevalence of both posttraumatic stress disorder (PTSD) and traumatic brain injury (TBI) among combat veterans. The diagnosis and management of PTSD when a comorbid TBI may also exist presents a challenge to interdisciplinary care teams at Department of Veterans Affairs (VA) and civilian medical facilities, particularly when the patient reports a history of blast exposure. Treatment recommendations from VA and Department of Defense's (DOD) recently updated VA/DOD Clinical Practice Guideline for Management of Post-Traumatic Stress are considered from the perspective of simultaneously managing comorbid TBI.

Posttraumatic stress disorder (PTSD) is a prevalent psychiatric diagnosis among veterans and has high comorbidity with other medical and psychiatric conditions. This article reviews the pharmacotherapy recommendations from the 2010 revised Department of Veterans Affairs/Department of Defense Clinical Practice Guideline (CPG) for PTSD and provides practical PTSD treatment recommendations for clinicians. While evidence-based, trauma-focused psychotherapy is the preferred treatment for PTSD, pharmacotherapy is also an important treatment option.

Background: Military service members are often exposed to at least one explosive event, and many blast-exposed veterans present with symptoms of traumatic brain injury. However, there is little information on the intensity and duration of blast necessary to cause brain injury.

Methods: Varying intensity shock tube blasts were focused on the head of anesthetized ferrets, whose thorax and abdomen were protected.

Recent studies have shown an increase in the frequency of traumatic brain injuries related to blast exposure. However, the mechanisms that cause blast neurotrauma are unknown. Blast neurotrauma research using computational models has been one method to elucidate that response of the brain in blast, and to identify possible mechanical correlates of injury.

Background: Clinical studies increasingly report brain injury and not pulmonary injury following blast exposures, despite the increased frequency of exposure to explosive devices. The goal of this study was to determine the effect of personal body armour use on the potential for primary blast injury and to determine the risk of brain and pulmonary injury following a blast and its impact on the clinical care of patients with a history of blast exposure.

Methods: A shock tube was used to generate blast overpressures on soft ballistic protective vests (NIJ Level-2) and hard protective vests (NIJ Level-4) while overpressure was recorded behind the vest.

Background: The widespread use of explosives by modern insurgents and terrorists has increased the potential frequency of blast exposure in soldiers and civilians. This growing threat highlights the importance of understanding and evaluating blast injury risk and the increase of injury risk from exposure to repeated blast effects.

Methods: Data from more than 3,250 large animal experiments were collected from studies focusing on the effects of blast exposure.

Blast-related traumatic brain injury is the most prevalent injury for combat personnel seen in the current conflicts in Iraq and Afghanistan, yet as a research community,we still do not fully understand the detailed etiology and pathology of this injury. Finite element (FE) modeling is well suited for studying the mechanical response of the head and brain to blast loading. This paper details the development of a FE head and brain model for blast simulation by examining both the dilatational and deviatoric response of the brain as potential injury mechanisms.

Traumatic brain injury (TBI) from blast produces a number of conundrums. This review focuses on five fundamental questions including: (1) What are the physical correlates for blast TBI in humans? (2) Why is there limited evidence of traditional pulmonary injury from blast in current military field epidemiology? (3) What are the primary blast brain injury mechanisms in humans? (4) If TBI can present with clinical symptoms similar to those of Post-Traumatic Stress Disorder (PTSD), how do we clinically differentiate blast TBI from PTSD and other psychiatric conditions? (5) How do we scale experimental animal models to human response? The preponderance of the evidence from a combination of clinical practice and experimental models suggests that blast TBI from direct blast exposure occurs on the modern battlefield. Progress has been made in establishing injury risk functions in terms of blast overpressure time histories, and there is strong experimental evidence in animal models that mild brain injuries occur at blast intensities that are similar to the pulmonary injury threshold.

Many soldiers returning from the current conflicts in Iraq and Afghanistan have had at least one exposure to an explosive event and a significant number have symptoms consistent with traumatic brain injury. Although blast injury risk functions have been determined and validated for pulmonary injury, there is little information on the blast levels necessary to cause blast brain injury. Anesthetized male New Zealand White rabbits were exposed to varying levels of shock tube blast exposure focused on the head, while their thoraces were protected.

Purpose: Medication adherence in combat veterans with traumatic brain injury (TBI) was evaluated.

Methods: Patients with a diagnosis of TBI were identified by a computer search of veterans enrolled in the Operation Enduring Freedom/Operation Iraqi Freedom or TBI/polytrauma clinics at Durham Veterans Affairs Medical Center (VAMC) between September 15, 2007, and September 15, 2008. Patients were included if they were at least 18 years old, received medical care and medications at the VAMC for at least 12 continuous months, and were taking at least one maintenance medication.
