RATIONALE: ±3,4-Methylenedioxymethamphetamine (MDMA, "ecstasy") is a stimulant-psychedelic drug with unique social effects. It may dampen reactivity to negative social stimuli such as social threat and rejection. Perhaps because of these effects, MDMA has shown promise as a treatment for post-traumatic stress disorder (PTSD). However, the effect of single doses of MDMA on responses to an acute psychosocial stressor has not been tested. OBJECTIVES: In this study, we sought to test the effects of MDMA on responses to stress in healthy adults using a public speaking task...

BACKGROUND: In randomised studies, the capsaicin 8% patch has demonstrated effective pain relief in patients with peripheral neuropathic pain (PNP) arising from different aetiologies. METHODS: ASCEND was an open-label, non-interventional study of patients with non-diabetes-related PNP who received capsaicin 8% patch treatment, according to usual clinical practice, and were followed for ≤52 weeks. Co-primary endpoints were percentage change in the mean numeric pain rating scale (NPRS) 'average daily pain' score from baseline to the average of Weeks 2 and 8 following first treatment; and median time from first to second treatment...

OBJECTIVES: Small series have suggested that outcomes after abusive head trauma are less favorable than after other injury mechanisms. We sought to determine the impact of abusive head trauma on mortality and identify factors that differentiate children with abusive head trauma from those with traumatic brain injury from other mechanisms. DESIGN: First 200 subjects from the Approaches and Decisions in Acute Pediatric Traumatic Brain Injury Trial-a comparative effectiveness study using an observational, cohort study design...

Posttraumatic stress disorder (PTSD) is a mental disorder developing after exposure to traumatic events. Although psychotherapy reveals some therapeutic effectiveness, clinically sustainable cure is still uncertain. Some Chinese herbal formulae are reported to work well clinically against mental diseases in Asian countries, but the safety and their mode of action are still unclear. In this study, we investigated the mechanisms of Chinese remedy free and easy wanderer (FAEW) on PTSD. We used a reverse pharmacology approach combining clinical data to search for mechanisms of PTSD with subsequent in vitro verification and bioinformatics techniques as follows: (1) by analyzing microarray-based transcriptome-wide mRNA expression profiling of PTSD patients; (2) by investigating the effect of FAEW and the antidepressant control drug fluoxetine on the transcription factor NF-κB using reporter cell assays and western blotting; (3) by performing molecular docking and literature data mining based on phytochemical constituents of FAEW...

BACKGROUND: Post-traumatic stress disorder (PTSD) is a serious psychological condition, which can develop both from physically experiencing and also from witnessing traumatic events. There is evidence that physical exercise can have a positive impact on the symptoms of PTSD. Relevant to this, in our previous pre-clinical work, beneficial effects of treadmill exercise were reported on PTSD-like behaviors in a social defeat paradigm, a rat model of direct physical trauma. However, the role of exercise on vicariously acquired PTSD-like phenotype was not examined...

BACKGROUND: Posttraumatic growth is the positive change resulting from traumatic experiences and is typically assessed with retrospective measures like the Posttraumatic Growth Inventory (PTGI). The PTGI was designed to include reference to a specific traumatic event, making it difficult to implement, without change, in prospective survey studies. Thus, a modified Posttraumatic Growth Inventory-Short Form (PTGI-SF) was included in a large prospective study of current and former U.S. military personnel...

Virtual reality has shown promising results in the treatment of posttraumatic stress disorder (PTSD) for some traumatic experiences, but sexual assault has been understudied. One important question to address is the relevance and safety of a virtual environment (VE) allowing patients to be progressively exposed to a sexual assault scenario. The aim of this study was to validate such a VE. Thirty women (victims and nonvictims of sexual assault) were randomly assigned in a counter-balanced order to 2 immersions in a virtual bar: a control scenario where the encounter with the aggressor does not lead to sexual assault and an experimental scenario where the participant is assaulted...

Effective emotion regulation (ER) is expected to protect mental health in traumatic stress. We first analysed the protective (moderator) function of different ER strategies and the associations between ER and mental health. Second, we tested gender differences in the protective function of ER and the associations between ER strategies and mental health. Participants were 482 Palestinian children (girls 49.4%; 10-13 years, M = 11.29, SD = .68) whose ER was assessed by the Emotion Regulation Questionnaire and mental health by post-traumatic stress (Children's Impact Event Scale), depressive, and psychological distress (Strengths and Difficulties Questionnaire) symptoms, and by psychosocial well-being (Mental Health Continuum-Short Form)...

REVIEW
Robert Motley, Whitney Sewell, Yu-Chih Chen
Black emerging adults ages 18-29, particularly those residing in predominantly black urban communities, are at risk for community violence exposure (CVE). This potentially traumatic event may induce traumatic stress reactions for black emerging adults that contribute to their engagement in violence perpetration, substance use and/or sexual risk-taking behaviors as a way to cope with their experiences. To address these identified concerns and make recommendations for future research, this article identifies and synthesizes results from studies that have examined CVE and its association with violence perpetration, substance use, and sexual risk-taking behaviors among black emerging adults...

BACKGROUND: The objective of this pilot study was to explore the use of a closed-loop, allostatic, acoustic stimulation neurotechnology for individuals with self-reported symptoms of post-traumatic stress, as a potential means to impact symptomatology, temporal lobe high frequency asymmetry, heart rate variability (HRV), and baroreflex sensitivity (BRS). METHODS: From a cohort of individuals participating in a naturalistic study to evaluate use of allostatic neurotechnology for diverse clinical conditions, a subset was identified who reported high scores on the Posttraumatic Stress Disorder Checklist (PCL)...

Posttraumatic stress disorder (PTSD) is a clinical condition that occurs after a discrete traumatic event, such as an accident or assault. Research into PTSD has primarily been adult-focused; however, there is a growing body of evidence evaluating the theory and treatment of PTSD in young children. Consequently, cognitive behavior therapy (CBT) interventions for PTSD in youth have been developed that focus on 3 core components of the cognitive model-a disorganized memory of the trauma, maladaptive appraisals of the trauma and its effects (meanings), and dysfunctional coping mechanisms (management)...

Negative outcomes of mild traumatic brain injury (mTBI) can be exacerbated by repeated insult. Animal models of repeated closed-head mTBI provide the opportunity to define acute pathological mechanisms as the number of mTBI increases. Furthermore, little is known about the effects of mTBI impact site, and how this may affect brain function. We use a closed head, weight drop model of mTBI that allows head movement following impact, in adult female rats to determine the role of the number and location of mTBI on brain pathology and behaviour...

INTRODUCTION: Anxiety sensitivity has been proposed as a psychological vulnerability factor for post-traumatic stress disorder (PTSD). Studies have also supported the protective role of resilience for overcoming the negative effects of trauma exposure. Given the linkages between anxiety sensitivity, resilience, trauma exposure and post-traumatic stress, this study explored the potential moderating roles of anxiety sensitivity and resilience on the association between trauma history and PTSD symptoms in a sample of individuals with chronic pain...

OBJECTIVE: Adverse early-life events are predisposing factors for functional neurological disorder (FND) and post-traumatic stress disorder (PTSD). Cingulo-insular regions are implicated in the biology of both conditions and are sites of stress-mediated neuroplasticity. We hypothesised that functional neurological symptoms and the magnitude of childhood abuse would be associated with overlapping anterior cingulate cortex (ACC) and insular volumetric reductions, and that FND and PTSD symptoms would map onto distinct cingulo-insular areas...

OBJECTIVE: The current scientific measures of posttraumatic changes in the wake of major stressors have mostly been unidirectional. This study is an attempt to develop a scale that will capture the continuum of positive to negative psychological changes after trauma. METHOD: Forty-five statements were presented to a veteran sample (N = 4,053) with the request to report for each item their experiences of negative, positive, or no posttraumatic changes as a result of their deployment to Afghanistan...

Pathological changes to the tau protein, including conformational changes and aggregation, are major hallmarks of a group of neurodegenerative disorders known as tauopathies. Among the conformational changes are alterations involving the extreme amino terminus of the protein, known as the phosphatase-activating domain (PAD). Aberrant PAD exposure induces a signaling cascade that leads to disruption of axonal transport, a critical function for neuronal survival. Conformational display of PAD is an early marker of pathological tau in Alzheimer disease (AD), but its role in other tauopathies has yet to be firmly established...

OBJECTIVE: Chest pain is one of the most common reasons people seek emergency care-and one of the most critical. In the United States, chest pain is the second most common reason for emergency department (ED) visits. A patient's primary complaint of "chest pain" may reflect a broad range of underlying causes; therefore, it is important that emergency medical service (EMS) agencies gain a thorough understanding of these cases, beginning with the initial management of chest pain in the 9-1-1 center...

Literature on the neurobiological bases of Post-Traumatic Stress Disorder (PTSD) considers medial Prefrontal cortex (mPFC), a core region of the Default Mode Network (DMN), as a region involved in response regulation to stressors. Disrupted functioning of the DMN has been recognized at the basis of the pathophysiology of a number of mental disorders. Furthermore, in the evaluation of the protective factors to trauma consequence, an important role has been assigned to resilience. Our aim was to investigate the specific relation of resilience and PTSD symptoms severity with resting state brain connectivity in a traumatized population using magnetoencephalography (MEG), a non-invasive imaging technique with high temporal resolution and documented advantages in clinical applications...

OBJECTIVE: To investigate the therapeutic potential of intra-articular hyaluronan-derivative HYADD® 4-G and/or platelet-rich plasma (PRP) in a mouse model of non-invasive joint injury. METHODS: Non-invasive axial tibial loading was used to induce joint injury in 10-week-old C57BL/6J mice (n = 86). Mice underwent a single loading of either 6 Newton (N) or 9N axial tibial compression. HYADD® 4-G was injected intra-articularly at 8 mg/mL or 15 mg/mL either before or after loading with or without PRP...
