In the aftermath of a traumatic event, many people suffer from psychological distress, but only a minority develops posttraumatic stress disorder (PTSD). Pre-trauma individual differences in fear conditioning, most notably reduced extinction learning, have been proposed as playing an important role in the etiology of PTSD. However, prospective data are lacking. In this study, we prospectively tested whether reduced extinction was a predictor for later posttraumatic stress. Dutch soldiers (N = 249) were administered a conditioning task before their four-month deployment to Afghanistan to asses individual differences in extinction learning. After returning home, posttraumatic stress was measured. Results showed that reduced extinction learning before deployment predicted subsequent PTSD symptom severity, over and beyond degree of pre-deployment stress symptoms, neuroticism, and exposure to stressors on deployment. The findings suggest that reduced extinction learning may play a role in the development of PTSD. Copyright © 2012 Elsevier Ltd. All rights reserved.

Traumatic defects are mostly accompanied by hard and soft tissue loss. This report describes the surgical and prosthetic treatment of a patient with post-traumatic mandibular defect. A split-thickness skin graft was performed prior to implant placement and prefabricated acrylic stent was placed to hold the graft in place. The esthetic and functional demands of the patient were fulfilled by implant-supported screw-retained fixed prosthesis using CAD-CAM technology. PMID:23508120
Fear Generalization and Anxiety: Behavioral and Neural Mechanisms.
Dunsmoor, Joseph E; Paz, Rony
2015-09-01
Fear can be an adaptive emotion that helps defend against potential danger. Classical conditioning models elegantly describe how animals learn which stimuli in the environment signal danger, but understanding how this learning is generalized to other stimuli that resemble aspects of a learned threat remains a challenge. Critically, the overgeneralization of fear to harmless stimuli or situations is a burden to daily life and characteristic of posttraumatic stress disorder and other anxiety disorders. Here, we review emerging evidence on behavioral and neural mechanisms of generalization of emotional learning with the goal of encouraging further research on generalization in anxiety disorders. We begin by placing research on fear generalization in a rich historical context of stimulus generalization dating back to Pavlov, which lays the foundation for theoretical and experimental approaches used today. We then transition to contemporary behavioral and neurobiological research on generalization of emotional learning in humans and nonhuman animals and discuss the factors that promote generalization on the one hand from discrimination on the other hand.

In this review article, genetic variation associated with brain responses related to acute and chronic stress reactivity and fear learning in humans is presented as an important mechanism underlying posttraumatic stress disorder. We report that genes related to the regulation of the hypothalamic-pituitary-adrenal axis, as well as genes that modulate serotonergic, dopaminergic, and neuropeptidergic functions or plasticity, play a role in this context. The strong overlap of the genetic targets involved in stress and fear learning suggests that a dimensional and mechanistic model of the development of posttraumatic stress disorder based on these constructs is promising. Genome-wide genetic analyses on fear and stress mechanisms are scarce. So far, reliable replication is still lacking for most of the molecular genetic findings, and the proportion of explained variance is rather small. Further analysis of neurogenetic stress and fear learning needs to integrate data from animal and human studies. Copyright © 2018 Society of Biological Psychiatry. Published by Elsevier Inc.

We assessed transgenerational effects of maternal traumatic exposure, posttraumatic stress symptoms and posttraumatic stress disorder on trauma-related symptoms in Cambodian offspring born after the genocidal Khmer Rouge Regime. We conducted a randomized cross-sectional study. N=378 mothers from 4 provinces of the country and one of each of their grown-up children were interviewed. Lifetime traumatic exposure was determined using a context-adapted event list. Present posttraumatic stress symptoms and a potential posttraumatic stress disorder were assessed using the civilian version of the Posttraumatic Stress Disorder Checklist. We found no indication of transgenerational effects that were directly related to maternal traumatic exposure, posttraumatic stress symptoms or posttraumatic stress disorder. Instead, a gender-specific moderating effect was found. Individual traumatic exposure had a stronger effect on posttraumatic stress symptoms in daughters, the higher the mother's lifetime traumatic exposure. There is evidence of an interaction between lifetime traumatic exposure of mothers and their offspring that can be interpreted as an increased vulnerability to symptoms of posttraumatic stress in daughters. The mechanisms of transgenerational trauma in the Cambodian context require further research, as learning from previous conflicts will be instructive when addressing the pressing humanitarian needs of today's world.

Associability-modulated loss learning is increased in posttraumatic stress disorder
Brown, Vanessa M; Zhu, Lusha; Wang, John M; Frueh, B Christopher
2018-01-01
Disproportionate reactions to unexpected stimuli in the environment are a cardinal symptom of posttraumatic stress disorder (PTSD). Here, we test whether these heightened responses are associated with disruptions in distinct components of reinforcement learning. Specifically, using functional neuroimaging, a loss-learning task, and a computational model-based approach, we assessed the mechanistic hypothesis that overreactions to stimuli in PTSD arise from anomalous gating of attention during learning (i.e., associability). Behavioral choices of combat-deployed veterans with and without PTSD were fit to a reinforcement learning model, generating trial-by-trial prediction errors (signaling unexpected outcomes) and associability values (signaling attention allocation to the unexpected outcomes). Neural substrates of associability value and behavioral parameter estimates of associability updating, but not prediction error, increased with PTSD during loss learning. Moreover, the interaction of PTSD severity with neural markers of associability value predicted behavioral choices. These results indicate that increased attention-based learning may underlie aspects of PTSD and suggest potential neuromechanistic treatment targets. PMID:29313489

Ventricular septal defects resulting from post-traumatic cardiac injury are very rare. Percutaneous closure has emerged as a method for treating this disorder. We wish to report our experience in three patients who underwent percutaneous closure of a post-traumatic ventricular septal defect with a patent ductus arteriosus occluder. We treated three patients with post-traumatic ventricular septal defects caused by stab wounds with knives. After the heart wound was repaired, patient examinations revealed ventricular septal defects with pulmonary/systemic flow ratios (Qp/Qs) of over 1.7. The post-traumatic ventricular septal defects were closed percutaneously with a patent ductus arteriosus occluder (Lifetech Scientific (Shenzhen) Co., LTD, Guangdong, China) utilizing standard techniques. Post-operative transthoracic echocardiography revealed no residual left-to-right shunt and indicated normal ventricular function. In addition, 320-slice computerized tomography showed that the occluder was well placed and exhibited normal morphology. Our experiences indicate that closure of a post-traumatic ventricular septal defect using a patent ductus arteriosus occluder is feasible, safe, and effective.

Learning processes have been implicated in the development and course of posttraumatic stress disorder (PTSD); however, little is currently known about punishment-based learning in PTSD. The current study investigated impairments in punishment-based learning in U.S. veterans. We expected that veterans with PTSD would demonstrate greater punishment-based learning compared to a non-PTSD control group. We compared a PTSD group with and without co-occurring depression (n = 27) to a control group (with and without trauma exposure) without PTSD or depression (n = 29). Participants completed a computerized probabilistic punishment-based learning task. Compared to the non-PTSD control group, veterans with PTSD showed significantly greater punishment-based learning. Specifically, there was a significant Block × Group interaction, F(1, 54) = 4.12, p = .047, η(2) = .07. Veterans with PTSD demonstrated greater change in response bias for responding toward a less frequently punished stimulus across blocks. The observed hypersensitivity to punishment in individuals with PTSD may contribute to avoidant responses that are not specific to trauma cues.

Pre-deployment identification of soldiers at risk for long-term posttraumatic stress psychopathology after home coming is important to guide decisions about deployment. Early post-deployment identification can direct early interventions to those in need and thereby prevents the development of chronic psychopathology. Both hold significant public health benefits given large numbers of deployed soldiers, but has so far not been achieved. Here, we aim to assess the potential for pre- and early post-deployment prediction of resilience or posttraumatic stress development in soldiers by application of machine learning (ML) methods. ML feature selection and prediction algorithms were applied to a prospective cohort of 561 Danish soldiers deployed to Afghanistan in 2009 to identify unique risk indicators and forecast long-term posttraumatic stress responses. Robust pre- and early postdeployment risk indicators were identified, and included individual PTSD symptoms as well as total level of PTSD symptoms, previous trauma and treatment, negative emotions, and thought suppression. The predictive performance of these risk indicators combined was assessed by cross-validation. Together, these indicators forecasted long term posttraumatic stress responses with high accuracy (pre-deployment: AUC = 0.84 (95% CI = 0.81-0.87), post-deployment: AUC = 0.88 (95% CI = 0.85-0.91)). This study utilized a previously collected data set and was therefore not designed to exhaust the potential of ML methods. Further, the study relied solely on self-reported measures. Pre-deployment and early post-deployment identification of risk for long-term posttraumatic psychopathology are feasible and could greatly reduce the public health costs of war.

Recovery of components of memory in post-traumatic amnesia.
Leach, Kathleen; Kinsella, Glynda; Jackson, Martin; Matyas, Tom
2006-11-01
Post-traumatic amnesia by definition indicates significant impairment of new learning ability, however very few studies have, examined the natural history and resolution of memory and new learning during PTA. Those studies which have, tended to examine orientation separately from the memory processes required to achieve orientation. Analysis of the order of recovery of the items of the Westmead PTA scale was used to examine recovery of memory and new learning capacity. The results of daily assessment of 34 patients with traumatic brain injury (TBI) on the Westmead PTA scale were analysed for order of recovery. The pattern of rank order of item recovery indicated that Date of Birth recovered consistently first. There was variability in the remaining items, however items reflecting long-term memory tended to recover second and items reflecting simple new learning followed. Recall of all three pictures reflecting complex new learning recovered last. The pattern of recovery of memory and new learning during PTA reflects a number of complex, inter-related variables including; the familiarity with the information, amount of rehearsal both before and since the accident and the number of cues available in the environment.

Combined post-traumatic aniridia and aphakia demand extensive and complex reconstructive surgery. We present our approach for simultaneous correction of this surgical situation with the use of the ArtificialIris (Dr. Schmidt Intraocularlinsen GmbH, Germany) with a foldable acrylic IOL Lentis L-313 (Oculentis, GmbH, Germany) sutured to its surface. The novelty (our first operation was on June 2010) of this surgical technique is based on the combined use of foldable (with closed haptics) IOL and Artificialiris to correct post-traumatic aniridia and aphakia. Four consecutive cases of combined post-traumatic lesions of iris and lens, corrected with complex device ArtificialIris and foldable IOL. In two cases, the compound implant was sutured to the sclera in sulcus during the penetrating keratoplasty; in another case, it was positioned through a corneal incision of about 5.0 mm with transscleral fixation, and in one patient with preserved capsular support and possibility of IOL in-the-bag implantation the ArtificialIris was placed in sulcus sutureless through a clear corneal tunnel. Maximal follow-up was 6 months. The complex device was placed firmly fixed within the sulcus, including in the eye implanted without sutures, and showed a stable and centered position without any tilt or torque. Management of post-traumatic aniridia combined with aphakia by haptic fixation of a foldable acrylic IOL on a foldable iris prosthesis appears to be a promising approach which gives the surgeon the possibility to correct a complex lesion with one procedure, which is less traumatic and faster. Existence of foldable materials, both iris and IOL, permits relatively small corneal incisions (4.0-5.0 mm). Moreover, the custom-tailored iris prosthesis gives a perfect aesthetic result.

A variety of occupational health hazards can cause employees to experience feelings of victimization and to develop work-related post-traumatic stress responses. The author presents assessment guidelines developed in work with people suffering from toxic exposures to help identify factors that can place employees at high risk for such stress responses. These guidelines can be adapted to evaluate employee reactions to any type of occupational injury. Clinicians also need to move beyond individual treatment approaches to address workplace and policy interventions.

To compare psychological recovery of patients receiving structured nurse-led follow-up and patients receiving usual care after intensive care discharge. Quasi-experimental study. Single centre, university hospital, mixed intensive care patient population. Symptoms of post-traumatic stress disorder, anxiety and depression measured three and four times over 12 months after intensive care discharge. Disturbing memories of the intensive care stay and psychological reactions (that one's life was in danger, threat to physical integrity, intense fear, helplessness, horror) three months after intensive care. A mixed effect model tested differences between the groups over time and regression model predicted post-traumatic stress at three months. The experimental group had significantly more symptoms of post-traumatic stress and anxiety than the control group over the 12 months. Patients from both groups had severe symptoms of post-traumatic stress. Patients with post-traumatic stress at three months had disturbing memories and psychological reactions. The structured nurse-led follow-up did not improve patients' measured outcomes of psychological recovery after intensive care. Patients with severe symptoms of post-traumatic stress are of concern. Emphasis needs to be placed on disturbing memories of the intensive care stay and psychological reactions when constructing intensive care nurse-led follow-up. Copyright © 2017 Elsevier Ltd.

To measure key neurocognitive performance effects following stellate ganglion block (SGB) administered to treat post-traumatic stress disorder (PTSD) symptoms. Eleven patients diagnosed, screened, and scheduled for SGB to treat their PTSD symptoms were administered a panel of eight cognitive measures before and 1 to 3 weeks after undergoing this procedure. PTSD symptoms were evaluated using the Posttraumatic Stress Disorder Checklist-Military. One to three weeks post-SGB, none of the patients showed any statistically significant decline in neurocognitive performance. Rather, there was a clear trend in improvement, with four out of eight measures reaching statistical significance following SGB. All patients improved in PTSD symptoms with a mean improvement on Posttraumatic Stress Disorder Checklist-Military of 29. In this case series of 11 patients, SGB effectively treated PTSD symptoms and did not impair reaction time, memory, or concentration. Therefore, SGB should be considered as a viable treatment option for personnel with PTSD symptoms who will be placed in demanding conditions such as combat.

Cognitive dysfunction is commonly observed among individuals with Alcohol Use Disorder (AUD) and trauma exposure and is, in turn, associated with worse clinical outcomes. Accordingly, disruptions in cognitive functioning may be conceptualized as a trans-disease phenomenon representing a potential high-yield target for intervention. Less is known though about how different cognitive functions co-vary with alcohol use, craving, and posttraumatic stress symptom severity among trauma exposed individuals with AUD. Sixty-eight male and female trauma exposed military Veterans with AUD, entering treatment trials to reduce alcohol use, completed measures assessing alcohol use and craving, posttraumatic stress symptom severity, and cognitive functioning. In multivariate models, after controlling for posttraumatic stress symptom severity, poorer learning and memory was associated with higher alcohol consumption and higher risk-taking/impulsivity was associated with stronger pre-occupations with alcohol and compulsions to drink. Alcohol consumption and craving, but not performance on cognitive tests, were positively associated with posttraumatic stress symptom severity. Findings suggest that interventions to strengthen cognitive functioning might be used as a preparatory step to augment treatments for AUD. Clinicians are encouraged to consider a standard assessment of cognitive functioning, in addition to posttraumatic stress symptom severity, in treatment planning and delivery for this vulnerable and high-risk population.

Early posttraumatic seizures may contribute to worsened outcomes after traumatic brain injury. Evidence to guide the evaluation and management of early posttraumatic seizures in children is limited. We undertook a survey of current practices of continuous electroencephalographic monitoring, seizure prophylaxis, and the management of early posttraumatic seizures to provide essential information for trial design and the development of posttraumatic seizure management pathways. Surveys were sent to site principal investigators at all 43 sites participating in the Approaches and Decisions in Acute Pediatric TBI trial at the time of the survey. Surveys consisted of 12 questions addressing strategies to 1) implement continuous electroencephalographic monitoring, 2) posttraumatic seizure prophylaxis, 3) treat acute posttraumatic seizures, 4) treat status epilepticus and refractory status epilepticus, and 5) monitor antiseizure drug levels. Institutions comprised a mixture of free-standing children's hospitals and university medical centers across the United States and Europe. Site principal investigators of the Approaches and Decisions in Acute Pediatric TBI trial. None. Continuous electroencephalographic monitoring was available in the PICU in the overwhelming majority of clinical sites (98%); however, the plans to operationalize such monitoring for children varied considerably. A similar majority of sites report that administration of prophylactic antiseizure medications is anticipated in children (93%); yet, a minority reports that a specified protocol for treatment of posttraumatic seizures is in place (43%). Reported medication choices varied substantially between sites, but the majority of sites reported pentobarbital for refractory status epilepticus (81%). The presence of treatment protocols for seizure prophylaxis, early posttraumatic seizures, posttraumatic status epilepticus, and refractory status epilepticus was associated with decreased reported medications (all p < 0.05). This study reports the current management practices for early posttraumatic seizures in select academic centers after pediatric severe traumatic brain injury. The substantial variation in continuous electroencephalographic monitoring implementation, choice of seizure prophylaxis medications, and management of early posttraumatic seizures across institutions was reported, signifying the areas of clinical uncertainty that will help provide focused design of clinical trials. Although sites with treatment protocols reported a decreased number of medications for the scenarios described, completion of the Approaches and Decisions in Acute Pediatric TBI trial will be able to determine if these protocols lead to decreased variability in medication administration in children at the clinical sites.

Background : New technologies may profoundly change our way of understanding psychiatric disorders including posttraumatic stress disorder (PTSD). Imaging and biomarkers, along with technological and medical informatics developments, might provide an answer regarding at-risk patient's identification. Recent advances in the concept of 'digital phenotype', which refers to the capture of characteristics of a psychiatric disorder by computerized measurement tools, is one paradigmatic example. Objective : The impact of the new technologies on health professionals practice in PTSD care remains to be determined. The recent evolutions could disrupt the clinical practices and practitioners in their beliefs, ethics and representations, going as far as questioning their professional culture. In the present paper, we conducted an extensive search to highlight the articles which reflect the potential of these new technologies. Method : We conducted an overview by querying PubMed database with the terms [PTSD] [Posttraumatic stress disorder] AND [Computer] OR [Computerized] OR [Mobile] OR [Automatic] OR [Automated] OR [Machine learning] OR [Sensor] OR [Heart rate variability] OR [HRV] OR [actigraphy] OR [actimetry] OR [digital] OR [motion] OR [temperature] OR [virtual reality]. Results : We summarized the synthesized literature in two categories: prediction and assessment (including diagnostic, screening and monitoring). Two independent reviewers screened, extracted data and quality appraised the sources. Results were synthesized narratively. Conclusions : This overview shows that many studies are underway allowing researchers to start building a PTSD digital phenotype using passive data obtained by biometric sensors. Active data obtained from Ecological Momentary Assessment (EMA) could allow clinicians to assess PTSD patients. The place of connected objects, Artificial Intelligence and remote monitoring of patients with psychiatric pathology remains to be defined. These tools must be explained and adapted to the different profiles of physicians and patients. The involvement of patients, caregivers and health professionals is essential to the design and evaluation of these new tools.

The Buffalo Cardio-metabolic Occupational Police Stress study, an occupational cohort study of police officers, was conducted to evaluate physiologic and stress measures in a high-risk occupation where occupational exposure to difficult criminal situations can lead to physiologic and psychological health consequences among those who enforce the law. The chronic exposure to human tragedy may place police officers at special risk for mental health disorders and the potential for misuse of alcohol or drugs. While exact etiologies of post-traumatic stress were not determined by this study, overall post-traumatic stress (PTS) prevalence rates among the police officers was 35%, with 10% of individuals demonstrating severe PTS symptomatology. Waking cortisol measures tended to be higher among officers with more PTS symptomatology, with some gender related differences noted. Given the increase in incarcerations for addictions related offenses over the past 20 years and the chronic exposure to human suffering and tragedy, early recognition of PTS symptoms is essential in making the diagnosis of post-traumatic stress in high-risk occupational cohorts. Providing early entry into treatment and subsequently attempting to eliminate or minimize long-term consequences of post-traumatic stress can have a significant impact on the prevention of long term sequelae of chronic stress, such as the use or misuse of drugs or alcohol.
Neural Systems for Cognitive and Emotional Processing in Posttraumatic Stress Disorder
Brown, Vanessa M.; Morey, Rajendra A.

Individuals with posttraumatic stress disorder (PTSD) show altered cognition when trauma-related material is present. PTSD may lead to enhanced processing of trauma-related material, or it may cause impaired processing of trauma-unrelated information. However, other forms of emotional information may also alter cognition in PTSD. In this review, we discuss the behavioral and neural effects of emotion processing on cognition in PTSD, with a focus on neuroimaging results. We propose a model of emotion-cognition interaction based on evidence of two network models of altered brain activation in PTSD. The first is a trauma-disrupted network made up of ventrolateral PFC, dorsal anterior cingulate cortex (ACC), hippocampus, insula, and dorsomedial PFC that are differentially modulated by trauma content relative to emotional trauma-unrelated information. The trauma-disrupted network forms a subnetwork of regions within a larger, widely recognized network organized into ventral and dorsal streams for processing emotional and cognitive information that converge in the medial PFC and cingulate cortex. Models of fear learning, while not a cognitive process in the conventional sense, provide important insights into the maintenance of the core symptom clusters of PTSD such as re-experiencing and hypervigilance. Fear processing takes place within the limbic corticostriatal loop composed of threat-alerting and threat-assessing components. Understanding the disruptions in these two networks, and their effect on individuals with PTSD, will lead to an improved knowledge of the etiopathogenesis of PTSD and potential targets for both psychotherapeutic and pharmacotherapeutic interventions.

Introduction Threat conditioning and extinction play an important role in anxiety disorders, obsessive compulsive disorder (OCD), and posttraumatic stress disorder (PTSD). Although these conditions commonly affect children, threat conditioning and extinction have been primarily studied in adults. However, differences in phenomenology and neural architecture prohibit the generalization of adult findings to youth. Areas covered A comprehensive literature search using PubMed and PsycInfo was conducted to identify studies that have used differential conditioning tasks to examine threat acquisition and extinction in youth. The information obtained from this review helps to clarify the influence of these processes on the etiology and treatment of youth with OCD, PTSD and other anxiety disorders. Thirty studies of threat conditioning and extinction were identified. Expert Commentary Youth with anxiety disorders, OCD, and PTSD have largely comparable threat acquisition relative to unaffected controls, with some distinctions noted for youth with PTSD or youth who have suffered maltreatment. However, impaired extinction was consistently observed across youth with these disorders and appears to be consistent with deficiencies in inhibitory learning. Incorporating strategies to improve inhibitory learning may improve extinction learning within extinction-based treatments like cognitive behavioral therapy (CBT). Strategies to improve inhibitory learning in CBT are discussed. PMID:27275519

The present study examined mechanisms underlying verbal memory impairments in patients with posttraumatic stress disorder (PTSD). Earlier studies have reported that the verbal learning and memory alterations in PTSD are related to impaired encoding, but the use of encoding and organizational strategies in patients with PTSD has not been fully explored. This study examined organizational strategies in 21 refugees/immigrants exposed to war and political violence who fulfilled DSM-IV criteria for chronic PTSD compared with a control sample of 21 refugees/immigrants with similar exposure, but without PTSD. The California Verbal Learning Test was administered to examine differences in organizational strategies and memory. The semantic clustering score was slightly reduced in both groups, but the serial cluster score was significantly impaired in the PTSD group and they also reported more items from the recency region of the list. In addition, intrusive errors were significantly increased in the PTSD group. The data support an assumption of changed memory strategies in patients with PTSD associated with a specific impairment in executive control. However, memory impairment and the use of ineffective learning strategies may not be related to PTSD symptomatology only, but also to self-reported symptoms of depression and general distress.

Female nurses and nursing personnel (N = 1,044) answered questions about lifetime violence victimization (e.g., childhood abuse, intimate partner violence, and workplace violence) at baseline and completed the Primary Care Posttraumatic Stress (PTS) Disorder screen and Center for Epidemiologic Studies Depression Scale 6 months later. Seven percent screened positive for comorbid posttraumatic stress-depression at 6-month monitoring. Workers who reported one, two, or three or more types of violence victimization at baseline had 2.41 (p < .10), 2.35 (p > .05), and 6.44 (p < .01) greater odds, respectively, of subsequently screening positive for comorbid PTS-depression compared to their counterparts who reported no violence victimization at baseline. These results suggest the need to provide female nurses and nursing personnel with information about (1) the risk cumulative violence victimization poses for poorer mental health and functioning, and (2) evidence-based trauma informed treatment options outside their place of employment for those affected by violence victimization who develop mental health symptoms.

Sensitization is a form of non-associative conditioning in which amplification of behavioral responses can occur following presentation of an aversive or noxious stimulus. Understanding the cellular and molecular underpinnings of sensitization has been an overarching theme spanning the field of learning and memory as well as that of pain research. In this review we examine how sensitization, both in the context of learning as well as pain processing, shares evolutionarily conserved behavioral, cellular/synaptic, and epigenetic mechanisms across phyla. First, we characterize the behavioral phenomenon of sensitization both in invertebrates and vertebrates. Particular emphasis is placed on long-term sensitization (LTS) of withdrawal reflexes in Aplysia following aversive stimulation or injury, although additional invertebrate models are also covered. In the context of vertebrates, sensitization of mammalian hyperarousal in a model of post-traumatic stress disorder (PTSD), as well as mammalian models of inflammatory and neuropathic pain is characterized. Second, we investigate the cellular and synaptic mechanisms underlying these behaviors. We focus our discussion on serotonin-mediated long-term facilitation (LTF) and axotomy-mediated long-term hyperexcitability (LTH) in reduced Aplysia systems, as well as mammalian spinal plasticity mechanisms of central sensitization. Third, we explore recent evidence implicating epigenetic mechanisms in learning- and pain-related sensitization. This review illustrates the fundamental and functional overlay of the learning and memory field with the pain field which argues for homologous persistent plasticity mechanisms in response to sensitizing stimuli or injury across phyla.

Stress-Induced Out-of-Context Activation of Memory
Ježek, Karel; Lee, Benjamin B.; Kelemen, Eduard; McCarthy, Katharine M.; McEwen, Bruce S.; Fenton, André A.
2010-01-01
Inappropriate recollections and responses in stressful conditions are hallmarks of post-traumatic stress disorder and other anxiety and mood disorders, but how stress contributes to the disorders is unclear. Here we show that stress itself reactivates memories even if the memory is unrelated to the stressful experience. Forced-swim stress one day after learning enhanced memory recall. One-day post-learning amnestic treatments were ineffective unless administered soon after the swim, indicating that a stressful experience itself can reactivate unrelated consolidated memories. The swim also triggered inter-hemispheric transfer of a lateralized memory, confirming stress reactivates stable memories. These novel effects of stress on memory required the hippocampus although the memories themselves did not, indicating hippocampus-dependent modulation of extrahippocampal memories. These findings that a stressful experience itself can activate memory suggest the novel hypothesis that traumatic stress reactivates pre-trauma memories, linking them to memory for the trauma and pathological facilitation of post-traumatic recall.

Alert Hypnotic Inductions: Use in Treating Combat Post-Traumatic Stress Disorder.
Eads, Bruce; Wark, David M
2015-10-01
Alert hypnosis can be a valuable part of the treatment protocol for the resolution of post-traumatic stress disorder (PTSD). Research indicates that combat veterans with PTSD are more hypnotically susceptible than the general population. For that reason, it is hypothesized that they should be better able to use hypnosis in treatment. As opposed to the traditional modality, eyes-open alert hypnosis allows the patient to take advantage of hypnotic phenomena while participating responsibly in work, social life, and recreation. Three case studies are reported on combat veterans with PTSD who learned to overcome their symptoms using alert hypnosis.
Stress-enhanced fear learning in rats is resistant to the effects of immediate massed extinction
Long, Virginia A.; Fanselow, Michael S.
2014-01-01
Enhanced fear learning occurs subsequent to traumatic or stressful events and is a persistent challenge to the treatment of post-traumatic stress disorder (PTSD). Facilitation of learning produced by prior stress can elicit an exaggerated fear response to a minimally aversive event or stimulus. Stress-enhanced fear learning (SEFL) is a rat model of PTSD; rats previously exposed to the SEFL 15 electrical shocks procedure exhibit several behavioral responses similar to those seen in patients with PTSD. However, past reports found that SEFL is not mitigated by extinction (a model of exposure therapy) when the spaced extinction began 24 h after stress. Recent studies found that extinction from 10 min to 1 h subsequent to fear conditioning “erased” learning, whereas later extinction, occurring from 24 to 72 h after conditioning did not. Other studies indicate that massed extinction is more effective than spaced procedures. Therefore, we examined the time-dependent nature of extinction on the stress-induced enhancement of fear learning using a massed trial’s procedure. Experimental rats received 15 foot shocks and were given either no extinction or massed extinction 10 min or 72 h later. Our present data indicate that SEFL, following traumatic stress, is resistant to immediate massed extinction. Experimental rats showed exaggerated new fear learning regardless of when extinction training occurred. Thus, post-traumatic reactivity such as SEFL does not seem responsive to extinction treatments.

Altered neural encoding of prediction errors in assault-related posttraumatic stress disorder.
Ross, Marisa C; Lenow, Jennifer K; Kilts, Clinton D; Cisler, Josh M

Posttraumatic stress disorder (PTSD) is widely associated with deficits in extinguishing learned fear responses, which relies on mechanisms of reinforcement learning (e.g., updating expectations based on prediction errors). However, the degree to which PTSD is associated with impairments in general reinforcement learning (i.e., outside of the context of fear stimuli) remains poorly understood. Here, we investigate brain and behavioral differences in general reinforcement learning between adult women with and without a current diagnosis of PTSD. 29 adult females (15 PTSD with exposure to assaultive violence, 14 controls) underwent a neutral reinforcement-learning task (i.e., two arm bandit task) during fMRI. We modeled participant behavior using different adaptations of the Rescorla-Wagner (RW) model and used Independent Component Analysis to identify timecourses for large-scale a priori brain networks. We found that an anticorrelated and risk sensitive RW model best fit participant behavior, with no differences in computational parameters between groups. Women in the PTSD group demonstrated significantly less neural encoding of prediction errors in both a ventral striatum/mPFC and anterior insula network compared to healthy controls. Weakened encoding of prediction errors in the ventral striatum/mPFC and anterior insula during a general reinforcement learning task, outside of the context of fear stimuli, suggests the possibility of a broader conceptualization of learning differences in PTSD than currently proposed in current neurocircuitry models of PTSD.

Substance abuse, memory, and post-traumatic stress disorder.
Tipps, Megan E; Raybuck, Jonathan D; Lattal, K Matthew
2014-07-01
A large body of literature demonstrates the effects of abused substances on memory. These effects differ depending on the drug, the pattern of delivery (acute or chronic), and the drug state at the time of learning or assessment. Substance use disorders involving these drugs are often comorbid with anxiety disorders, such as post-traumatic stress disorder (PTSD). When the cognitive effects of these drugs are considered in the context of the treatment of these disorders, it becomes clear that these drugs may play a deleterious role in the development, maintenance, and treatment of PTSD. In this review, we examine the literature evaluating the cognitive effects of three commonly abused drugs: nicotine, cocaine, and alcohol. These three drugs operate through both common and distinct neurobiological mechanisms and alter learning and memory in multiple ways. We consider how the cognitive and affective effects of these drugs interact with the acquisition, consolidation, and extinction of learned fear, and we discuss the potential impediments that substance abuse creates for the treatment of PTSD.

Individuals with posttraumatic stress disorder (PTSD) are haunted by persistent memories of the trauma, but ironically are impaired in memories of daily life. The current set of 4 experiments compared new learning and memory of emotionally neutral content in 2 groups of patients and aged- and education-matched controls: 20 patients diagnosed with chronic posttraumatic stress disorder (C-PTSD) and 20 patients diagnosed with acute stress disorder (ASD). In all experiments, participants studied a list of stimuli pairs (words or pictures) and were then tested for their memory of the items, or for the association between items in each pair. Results indicated that both types of patients showed associative memory impairment compared to a control group, although their item memory performance was relatively intact. Potential mechanisms underlying such associative memory deficits in posttraumatic patients are discussed. Copyright © 2011 International Society for Traumatic Stress Studies.
Virtual Reality-Enhanced Extinction of Phobias and Post-Traumatic Stress.
Maples-Keller, Jessica L; Yasinski, Carly; Manjin, Nicole; Rothbaum, Barbara Olasov
2017-07-01
Virtual reality (VR) refers to an advanced technological communication interface in which the user is actively participating in a computer-generated 3-dimensional virtual world that includes computer sensory input devices used to simulate real-world interactive experiences. VR has been used within psychiatric treatment for anxiety disorders, particularly specific phobias and post-traumatic stress disorder, given several advantages that VR provides for use within treatment for these disorders. Exposure therapy for anxiety disorder is grounded in fear-conditioning models, in which extinction learning involves the process through which conditioned fear responses decrease or are inhibited. The present review will provide an overview of extinction training and anxiety disorder treatment, advantages for using VR within extinction training, a review of the literature regarding the effectiveness of VR within exposure therapy for specific phobias and post-traumatic stress disorder, and limitations and future directions of the extant empirical literature.
[Patients assaulted in psychiatric institutions: Literature review and clinical implications].
Ladois-Do Pilar Rei, A; Chraïbi, S
2018-02-01
The psychiatric ward is a place where all forms of violence are treated. Occasionally, this violence involves acts of aggression between patients in emergency psychiatric units or hospital wards. Such events can lead to the development or worsening of posttraumatic stress disorder. To establish the context, we first examined the epidemiology data concerning posttraumatic stress disorder in psychiatric patients who were frequently exposed to assaults. Secondly, we examined the issue of sexual and physical assaults between patients receiving treatment in a psychiatric ward. In this context, we studied possible occurrence of posttraumatic stress disorder associated with exposure to assaults of this kind. In certain cases, potentially traumatic exposure to violence was unknown to the medical staff or not taken into consideration. This would induce a risk of later development of posttraumatic stress disorder that would not be treated during the stay in psychiatry. To date, few scientific studies have focused on the proportion of patients assaulted by other patients during treatment in a psychiatric ward and the subsequent development of peritraumatic reactions and/or posttraumatic stress disorder associated with these assaults. We know that an insufficient number of public and private health institutions report the existence of such facts to the competent authorities. Also, a minority of clinicians and caregivers are trained in screening and management of trauma victims. Yet, these issues are particularly relevant in the scope of public health and health promotion. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

In this article, the authors present a psychodynamically oriented psychotherapy approach for posttraumatic stress disorder (PTSD) related to childhood abuse. This neurobiologically informed, phase-oriented treatment approach, which has been developed in Germany during the past 20 years, takes into account the broad comorbidity and the large degree of ego-function impairment typically found in these patients. Based on a psychodynamic relationship orientation, this treatment integrates a variety of trauma-specific imaginative and resource-oriented techniques. The approach places major emphasis on the prevention of vicarious traumatization. The authors are presently planning to test the approach in a randomized controlled trial aimed at strengthening the evidence base for psychodynamic psychotherapy in PTSD.

There have been significant advancements in the pharmacologic management of posttraumatic stress disorder (PTSD) in the past two decades. Multisite randomized clinical trials (RCTs) have noted the efficacy of selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNR Is) for PTSD treatment. Unfortunately, there have been no new medications approved to treat PTSD in the past 10 years. Although there have been exciting new findings in our knowledge of the neurobiology of PTSD, clinical trials testing new medications have lagged. This review summarizes recent research that builds on the unique pathophysiology of PTSD and suggests ways to move the field forward.

The current wave of terrorism which is taking place in Israel is characterized by increased arbitrary attacks by individual terrorists, acting independently, with reduced ability to anticipate when and where the next attack will take place. This situation creates an atmosphere of fear and insecurity in the lives of many citizens. Accordingly, the current study aims to establish a connection between death anxiety and PTSD symptom severity, as well as to examine whether major personality characteristics may moderate this connection. Using an online survey, 429 adult participants were recruited, and filled out death anxiety and PTSD symptomatology scales, as well as a short version of the Big Five personality scale. Findings revealed that death anxiety was a significant predictor of posttraumatic symptom severity, as were personality characteristics. Moreover, two personality traits, emotional stability and conscientiousness, moderated the association between death anxiety and PTSD symptomatology. The importance of death anxiety as a factor which is associated with PTSD symptomatology is discussed. Copyright © 2016. Published by Elsevier Ireland Ltd.

Background Former studies suggest that prior exposure to adverse experiences such as violence or sexual abuse increases vulnerability to posttraumatic stress reactions in victims of subsequent trauma. However, little is known about how such a history affects responses to terror in the general adolescent population. Objective To explore the role of prior exposure to adverse experiences as risk factors for posttraumatic stress reactions to the Oslo Terror events. Method We used data from 10,220 high school students in a large cross-sectional survey of adolescents in Norway that took place seven months after the Oslo Terror events. Prior exposure assessed was: direct exposure to violence, witnessing of violence, and unwanted sexual acts. We explored how these prior adversities interact with well-established risk factors such as proximity to the events, perceived life threat during the terror events, and gender. Results All types of prior exposure as well as the other risk factors were associated with terror-related posttraumatic stress reactions. The effects of prior adversities were, although small, independent of adolescents’ proximity to the terror events. Among prior adversities, only the effect of direct exposure to violence was moderated by perceived life threat. Exposure to prior adversities increased the risk of posttraumatic stress reactions equally for both genders, but proximity to the terror events and perceived life threat increased the risk more in females. Conclusions Terror events can have a more destabilizing impact on victims of prior adversities, independent of their level of exposure. The findings may be relevant to mental health workers and others providing post-trauma health care. PMID:24872862

Animal models for posttraumatic stress disorder: An overview of what is used in research
Borghans, Bart; Homberg, Judith R
2015-01-01
Posttraumatic stress disorder (PTSD) is a common anxiety disorder characterised by its persistence of symptoms after a traumatic experience. Although some patients can be cured, many do not benefit enough from the psychological therapies or medication strategies used. Many researchers use animal models to learn more about the disorder and several models are available. The most-used physical stressor models are single-prolonged stress, restraint stress, foot shock, stress-enhanced fear learning, and underwater trauma. Common social stressors are housing instability, social instability, early-life stress, and social defeat. Psychological models are not as diverse and rely on controlled exposure to the test animal’s natural predator. While validation of these models has been resolved with replicated symptoms using analogous stressors, translating new findings to human patients remains essential for their impact on the field. Choosing a model to experiment with can be challenging; this overview of what is possible with individual models may aid in making a decision. PMID:26740930

To examine the relationships between self-reported posttraumatic stress disorder (PTSD) symptoms, perceived positive relations with others, self-regulation strategy use, and academic motivation among student service members/veterans (SSM/V) enrolled in postsecondary education. SSM/V (N = 214), defined as veterans, active duty, or National Guard/Reservists of the US military, enrolled at 5 different institutions in Fall 2012. Data were collected using an online questionnaire that included standardized measures of PTSD symptoms, perceived quality of personal relations, academic self-regulation strategy use, and academic motivation. PTSD symptoms were associated with lower self-efficacy for learning and maladaptive academic goal orientation. Additionally, PTSD symptoms were associated with lower effort regulation (ie, persistence) during academic work. Endorsement of more positive relations moderated the deleterious relationship between PTSD symptoms and maladaptive goal orientation. The results suggest that postsecondary personnel adopt a social-cognitive framework to develop social, mental health, and academic supports for SSM/V with PTSD.

Nonmedical prescription drug use, defined as using the drug without a prescription or in ways for which it is not prescribed, and traumatic event exposure are highly prevalent among college students. Despite evidence that posttraumatic stress symptoms could place college students at risk for nonmedical prescription drug problems, no studies have examined this relationship. This study was a preliminary examination of posttraumatic stress symptoms, lifetime nonmedical prescription drug use, hazardous use, and dependence symptoms among college students with trauma exposure. Participants were students attending a rural college in Virginia, recruited through psychology classes, flyers, LISTSERVs, and announcements at student events. All students who reported experiencing at least one traumatic event were included (N = 119); participants' mean age was 19.7 years (SD = 1.90), about half were women (n = 63, 53%), and most were Caucasian (n = 103, 87%). Nearly 60% of participants (n = 71) reported using nonmedical prescription drugs at least once during their lifetime and were more likely than those with no use to report hazardous alcohol use (p < .01) and depressive symptoms (p < .05). There were no other significant differences between those who did and did not report use of nonmedical prescription drugs. Regression analyses showed that posttraumatic stress symptom frequency was positively associated with hazardous nonmedical prescription drug use, after controlling for gender, depressive symptoms, and hazardous alcohol use (p < .001). Posttraumatic stress symptom frequency was higher for those with any nonmedical prescription drug dependence symptoms (p < .001), but was unrelated to whether the student had ever engaged in nonmedical prescription drug use. Findings suggest that consideration of the types of behaviors and problems a college student is experiencing related to nonmedical prescription drug use may be more relevant to posttraumatic stress symptom frequency than dichotomous measures of nonmedical prescription drug use alone. Further, the association between the frequency of posttraumatic stress symptoms and both hazardous nonmedical prescription drug use and dependence symptoms among college students with a trauma history deserves further investigation due to the resulting vulnerability to increasingly negative outcomes.
Retrospective analysis of the recovery of orientation and memory during posttraumatic amnesia.

Prospective monitoring of posttraumatic amnesia (PTA) is recommended following moderate to severe traumatic brain injury (TBI). However, few studies have examined the typical order in which items recover on PTA scales. Different methods have been used to define recovery, and the order reported is not consistent across the literature. The purpose of this study was to improve understanding of the progression of PTA by reporting the duration to recovery of items and categories on the Westmead Post-Traumatic Amnesia Scale (WPTAS) according to different criteria. A retrospective analysis was conducted of 66 patients with TBI who were administered the WPTAS during hospital admission. The duration to recovery of items and categories was determined according to 3 criteria: first correct, correct 3 times in a row, and consistently correct. On the basis of the sample mean, date of birth (DOB), year, age, place, month, day, name, and memory for the 3 pictures recovered in this order according to all 3 criteria. However, the significance of differences between items and the order of recovery of categories depended on the criterion adopted. Although DOB recovered first in 74% of cases and the 3 pictures last in 63% of cases, there was a high degree of individual variability in the precise sequence of recovery. The traditional view of PTA recovering in the order of person, place, time, and memory does not adequately describe the profile of recovery on the WPTAS. Considering the recovery of individual items is necessary to understand and account for individuals differences in the order of recovery. (c) 2015 APA, all rights reserved).

Significant rates of intimate partner violence (IPV) perpetration have been identified among men with military backgrounds. Research indicates posttraumatic stress symptoms place military men at increased risk for IPV perpetration, but may be negatively associated with IPV among nonmilitary samples. However, no previous studies have directly compared court-referred IPV offenders with and without military experience, which may have clinical implications if posttraumatic stress symptoms are differentially associated with IPV perpetration across these two samples. Twenty court-referred IPV offenders with military background were demographically matched with 40 court-referred IPV offenders without military background. As anticipated, self- and partner-report of physically assaultive acts and injurious acts during baseline assessment showed significantly greater physical assault and injury perpetrated by offenders with military background. However, 1-year follow-up data on convictions indicated a significantly lower rate of recidivism among offenders with military background than among nonmilitary offenders. As hypothesized, symptoms of posttraumatic stress at intake showed a significant positive correlation with IPV perpetration among offenders with military background; however, this relationship showed a negative correlation among offenders without military background. Clinical implications are discussed including treatment avenues, such as Veterans Courts and other incarceration diversion programs, which may be particularly appropriate for offenders with military backgrounds.

Aversive olfactory associative memory loses odor specificity over time

ABSTRACT Avoiding associatively learned predictors of danger is crucial for survival. Aversive memories can, however, become counter-adaptive when they are overly generalized to harmless cues and contexts. In a fruit fly odor–electric shock associative memory paradigm, we found that learned avoidance lost its specificity for the trained odor and became general to novel odors within a day of training. We discuss the possible neural circuit mechanisms of this effect and highlight the parallelism to over-generalization of learned fear behavior after an incubation period in rodents and humans, with due relevance for post-traumatic stress disorder.

The strength of aversive and appetitive associations and maladaptive behaviors.
Itzhak, Yossef; Perez-Lanza, Daniel; Liddie, Shervin
2014-08-01
Certain maladaptive behaviors are thought to be acquired through classical Pavlovian conditioning. Exaggerated fear response, which can develop through Pavlovian conditioning, is associated with acquired anxiety disorders such as post-traumatic stress disorders (PTSDs). Inflated reward-seeking behavior, which develops through Pavlovian conditioning, underlies some types of addictive behavior (e.g., addiction to drugs, food, and gambling). These maladaptive behaviors are dependent on associative learning and the development of long-term memory (LTM). In animal models, an aversive reinforcer (fear conditioning) encodes an aversive contextual and cued LTM. On the other hand, an appetitive reinforcer results in conditioned place preference (CPP) that encodes an appetitive contextual LTM. The literature on weak and strong associative learning pertaining to the development of aversive and appetitive LTM is relatively scarce; thus, this review is particularly focused on the strength of associative learning. The strength of associative learning is dependent on the valence of the reinforcer and the salience of the conditioned stimulus that ultimately sways the strength of the memory trace. Our studies suggest that labile (weak) aversive and appetitive LTM may share similar signaling pathways, whereas stable (strong) aversive and appetitive LTM is mediated through different pathways. In addition, we provide some evidence suggesting that extinction of aversive fear memory and appetitive drug memory is likely to be mediated through different signaling molecules. We put forward the importance of studies aimed to investigate the molecular mechanisms underlying the development of weak and strong memories (aversive and appetitive), which would ultimately help in the development of targeted pharmacotherapies for the management of maladaptive behaviors that arise from classical Pavlovian conditioning. © 2014 International Union of Biochemistry and Molecular Biology.

The prevalence of post-traumatic stress disorder (PTSD) is higher among HIV-infected (HIV+) women compared with HIV-uninfected (HIV-) women, and deficits in episodic memory are a common feature of both PTSD and HIV infection. We investigated the association between a probable PTSD diagnosis using the PTSD Checklist-Civilian (PCL-C) version and verbal learning and memory using the Hopkins Verbal Learning Test in 1004 HIV+ and 496 at-risk HIV- women. HIV infection was not associated with a probable PTSD diagnosis (17% HIV+, 16% HIV-; p = 0.49) but was associated with lower verbal learning (p < 0.01) and memory scores (p < 0.01). Irrespective of HIV status, a probable PTSD diagnosis was associated with poorer performance in verbal learning (p < 0.01) and memory (p < 0.01) and psychomotor speed (p < 0.001). The particular pattern of cognitive correlates of probable PTSD varied depending on exposure to sexual abuse and/or violence, with exposure to either being associated with a greater number of cognitive domains and a worse cognitive profile. A statistical interaction between HIV serostatus and PTSD was observed on the fine motor skills domain (p = 0.03). Among women with probable PTSD, HIV- women performed worse than HIV+ women on fine motor skills (p = 0.01), but among women without probable PTSD, there was no significant difference in performance between the groups (p = 0.59). These findings underscore the importance of considering mental health factors as correlates to cognitive deficits in women with HIV.
[Influence of stress on learning and memory].
Ukai, M
2000-08-01
This paper describes the influence of stress on learning and memory. The mice receiving inescapable electroshock fail to perform the active conditioned avoidance response of lever-pressing. This is called learned helplessness, which is ameliorated by treatment with antidepressants including one of the selective serotonin reuptake inhibitors (SSRIs). It is of particular interest that posttraumatic stress disease (PTSD) accompanied by memory impairment could be improved by treatment with SSRIs. The different kinds of stress including ischemia, footshock, psychological stress, and forced swimming influence learning and memory as indexed by spontaneous alternation performance as well as passive avoidance learning. In addition, a variety of stresses influence the activity of hormones and neurotransmitters like monoamines, neuropeptides, and excitatory amino acids resulting in changes in learning and memory. Finally, the accumulation of data is necessary to clarify the exact mechanism of stress on learning and memory.

Risk management and climate adaptation literature focuses mainly on reducing the impacts of, exposure to, and vulnerability to extreme events such as floods and droughts. Posttraumatic stress disorder is one of the most important impacts related to these events, but also a relatively under-researched topic outside original psychopathological contexts. We conduct a survey to investigate the mental stress caused by floods. We focus on hydrological, individual, and collective drivers of posttraumatic stress. We assess stress with flood-specific health scores and the GHQ-12 General Health Questionnaire. Our findings show that the combination of water depth and flood velocity measured via a Hazard Class Index is an important stressor; and that mental health resilience can be significantly improved by providing the population with adequate information. More specifically, the paper shows that psychological distress can be reduced by (i) coordinating awareness of flood risks and flood protection and prevention behavior; (ii) developing the ability to protect oneself from physical, material and intangible damage; (iii) designing simple insurance procedures and protocols for fast recovery; and (iv) learning from previous experiences.

This review highlights the neurobiological aspects of sex differences in posttraumatic stress disorder (PTSD), specifically focusing on the physiological responses to trauma and presents evidence supporting hormone and neurosteroid/peptide differences from both preclinical and clinical research. While others have suggested that trauma type or acute emotional reaction are responsible for women's disproportionate risk to PTSD, neither of these explanations fully accounts for the sex differences in PTSD. Sex differences in brain neurocircuitry, anatomy, and neurobiological processes, such as those involved in learning and memory, are discussed as they have been implicated in risk and resilience for the development of PTSD. Gonadal and stress hormones have been found to modulate sex differences in the neurocircuitry and neurochemistry underlying fear learning and extinction. Preclinical research has not consistently controlled for hormonal and reproductive status of rodents nor have clinical studies consistently examined these factors as potential moderators of risk for PTSD. Sex as a biological variable (SABV) should be considered, in addition to the endocrine and reproductive status of participants, in all stress physiology and PTSD research.

To prospectively evaluate the outcome of dental implants placed in the post-traumatic anterior maxilla after ridge augmentation with cancellous freeze-dried block bone allografts. Patients presenting with a history of anterior dentoalveolar trauma with bony deficiencies in the sagittal (≥3 mm) and vertical (<3 mm) planes according to computed tomography were included. The recipient sites were reconstructed with cancellous bone block allografts. After 6 months of healing, implants were placed. The primary outcomes of interest were 1) bone measurements taken before grafting, at the time of implant placement, and at stage 2 operations; 2) implant survival; and 3) complications. The sample was composed of 20 consecutive patients with a mean age of 25 ± 7 years. We used 28 cancellous allogeneic bone blocks, and 31 implants were inserted. Of the 31 implants, 12 were immediately restored. The mean follow-up was 42 ± 15 months. Graft and implant survival rates were 92.8% and 96.8%, respectively. Mean bone gain in the sagittal and vertical planes was 5 ± 0.5 mm horizontally and 2 ± 0.5 mm (P < .001). Successful restoration was achieved in all patients with fixed implant-supported prostheses. Soft tissue complications occurred in 7 patients (35%). Complications after cementation of the crowns were seen in 3 implants (9.6%). All implants remained clinically osseointegrated at the end of the follow-up examination. There was no crestal bone loss around the implants beyond the first implant thread. Cancellous block allograft can be used successfully for post-traumatic implant-supported restoration in the anterior maxilla. Copyright © 2011 American Association of Oral and Maxillofacial Surgeons.

Dissociative Identity Disorder (DID), a chronic childhood onset posttraumatic stress disorder, is currently recognized as a treatable condition. It is considered the paradigmatic dissociative condition and carries with it extreme posttraumatic symptomatology. Therapists skilled in the treatment of DID are typically fluent in the uses of hypnosis for stabilization, affect management, building a safe place and grounding to name of few. EMDR, which has come to the forefront of clinical awareness in the last ten years, seems aptly suited for the treatment of trauma, but can be destabilizing. This paper proposes a protocol, called Wreathing Protocol, for the imbricated use of EMDR and hypnosis in the treatment of not only DID (though this will be the primary focus of the paper), but also Dissociative Disorder Not Otherwise Specified (DDNOS) and chronic Posttraumatic Stress Disorder (PTSD). This protocol is useful to advanced clinicians skilled in both modalities independently. The sequential steps of the Wreathing Protocol will be described and illustrated by a clinical vignette on DID. The clinical implications of the use of the Wreathing Protocol will be discussed in DID as well as the chronic post traumatic spectrum.
Expert witness evaluation of posttraumatic stress disorder (PTSD) and return to work.
Precin, Pat
2011-01-01
This author was hired by a defendant's attorney as an expert witness in the evaluation of a plaintiff who filed a lawsuit for the loss of her job and concomitant income due to posttraumatic stress disorder (PTSD) symptoms acquired after sustaining a traumatic injury. This writer evaluated her symptoms, level of function, roles, and interests using a variety of assessments. This case study is a report of the evaluation. The results indicated that the plaintiff developed adequate coping mechanisms to manage her symptoms of PTSD in order to function in her diverse and chosen roles of worker, mother, care giver, wife, family member, volunteer, home maintainer, and religious participant even though she did not return to her prior place of employment. Because of these results, the case was settled out of court in the favor of the defendant.

Psychodynamic psychotherapists treating posttraumatic stress disorder (PTSD) sufferers can draw on an accumulated body of trauma studies from their own field to guide their work. However, these reports, often based on case studies or conceptual reviews, do not have the same empirical conclusiveness as more recent evidence-based research demonstrating the efficacy of cognitive-behavioral and body-oriented therapies. In this article, a psychodynamic psychotherapist reflects on his treatment of an Israeli man who developed PTSD after enduring 4 terrorist attacks. The author shows how assimilative integration offered him a theory- and research-based model that helped him comfortably combine separate treatment interventions. He also shows how this model helped him locate with some precision the specific contribution of psychodynamic psychotherapy. (PsycINFO Database Record (c) 2010 APA, all rights reserved).

The objective of this pilot study was to design, develop, and evaluate a predeployment stress inoculation training (PRESIT) preventive intervention to enable deploying personnel to cope better with combat-related stressors and mitigate the negative effects of trauma exposure. The PRESIT program consisted of three predeployment training modules: (1) educational materials on combat and operational stress control, (2) coping skills training involving focused and relaxation breathing exercises with biofeedback, and (3) exposure to a video multimedia stressor environment to practice knowledge and skills learned in the first two modules. Heart rate variability assessed the degree to which a subset of participants learned the coping skills. With a cluster randomized design, data from 351 Marines randomized into PRESIT and control groups were collected at predeployment and from 259 of these who responded to surveys on return from deployment. Findings showed that the PRESIT group reduced their physiological arousal through increased respiratory sinus arrhythmia during and after breathing training relative to controls. Logistic regression, corrected for clustering at the platoon level, examined group effects on post-traumatic stress disorder (PTSD) as measured by the Post-traumatic Stress Checklist after controlling for relevant covariates. Results showed that PRESIT protected against PTSD among Marines without baseline mental health problems. Although limited by a small number of participants who screened positive for PTSD, this study supports the benefits of PRESIT as a potential preventive strategy in the U.S. military personnel.

The odds-ratio of smoking is elevated in populations with neuropsychiatric diseases, in particular in the highly prevalent diagnoses of post-traumatic stress and anxiety disorders. Yet, the association between smoking and a key dimensional phenotype of these disorders-maladaptive deficits in fear learning and fear inhibition-is unclear. We therefore investigated acquisition and memory of fear and fear inhibition in healthy smoking and non-smoking participants (N=349, 22% smokers). We employed a well validated paradigm of context-dependent fear and safety learning (day 1) including a memory retrieval on day 2. During fear learning, a geometrical shape was associated with an aversive electrical stimulation (classical fear conditioning, in danger context) and fear responses were extinguished within another context (extinction learning, in safe context). On day 2, the conditioned stimuli were presented again in both contexts, without any aversive stimulation. Autonomic physiological measurements of skin conductance responses as well as subjective evaluations of fear and expectancy of the aversive stimulation were acquired. We found that impairment of fear inhibition (extinction) in the safe context during learning (day 1) was associated with the amount of pack-years in smokers. During retrieval of fear memories (day 2), smokers showed an impairment of contextual (safety context-related) fear inhibition as compared with non-smokers. These effects were found in physiological as well as subjective measures of fear. We provide initial evidence that smokers as compared with non-smokers show an impairment of fear inhibition. We propose that smokers have a deficit in integrating contextual signs of safety, which is a hallmark of post-traumatic stress and anxiety disorders.

Recent cross-sectional studies have shown that the inability to suppress fear under safe conditions is a key problem in people with posttraumatic stress disorder (PTSD). The current longitudinal study examined whether individual differences in fear inhibition predict the persistence of PTSD symptoms. Approximately 2 months after deployment to Afghanistan, 144 trauma-exposed Dutch soldiers were administered a conditional discrimination task (AX+/BX-). In this paradigm, A, B, and X are neutral stimuli. X combined with A is paired with a shock (AX+ trials); X combined with B is not (BX- trials). Fear inhibition was measured (AB trials). Startle electromyogram responses and shock expectancy ratings were recorded. PTSD symptoms were measured at 2 months and at 9 months after deployment. Results showed that greater startle responses during AB trials in individuals who discriminated between danger (AX+) and safety (BX-) during conditioning, predicted higher PTSD symptoms at 2 months and 9 months post-deployment. The predictive effect at 9 months remained significant after controlling for critical incidents during previous deployments and PTSD symptoms at 2 months. Responses to AX+ or BX- trials, or discrimination learning (AX+ minus BX-) did not predict PTSD symptoms. It is concluded that impaired fear inhibition learning seems to be involved in the persistence of PTSD symptoms. Copyright © 2013 Elsevier Ltd. All rights reserved.
Chronic Pain and Chronic Stress: Two Sides of the Same Coin?
Abdallah, Chadi G; Geha, Paul
2017-02-01
Pain and stress share significant conceptual and physiological overlaps. Both phenomena challenge the body's homeostasis and necessitate decision-making to help animals adapt to their environment. In addition, chronic stress and chronic pain share a common behavioral model of failure to extinguish negative memories. Yet, they also have discrepancies such that the final brain endophenotype of posttraumatic stress disorder, depression, and chronic pain appears to be different among the three conditions, and the role of the hypothalamic-pituitary-adrenal axis remains unclear in the physiology of pain. Persistence of either stress or pain is maladaptive and could lead to compromised well-being. In this brief review, we highlight the commonalities and differences between chronic stress and chronic pain, while focusing particularly on the central role of the limbic brain. We assess the current attempts in the field to conceptualize and understand chronic pain, within the context of knowledge gained from the stress literature. The limbic brain-including hippocampus, amygdala, and ventromedial pre-frontal cortex-plays a critical role in learning. These brain areas integrate incoming nociceptive or stress signals with internal state, and generate learning signals necessary for decision-making. Therefore, the physiological and structural remodeling of this learning circuitry is observed in conditions such as chronic pain, depression, and posttraumatic stress disorder, and is also linked to the risk of onset of these conditions.
Posttraumatic growth and recovery from addiction.
Haroosh, Eyal; Freedman, Sara
2017-01-01
Background : It is well documented that individuals coping with adverse events report both negative outcomes, such as posttraumatic stress symptoms, as well as positive changes, described as posttraumatic growth. Positive changes are also reported in people who have recovered from substance abuse. It seems plausible from the literature that both of these types of positive changes have elements in common. To date, no published studies have examined positive outcomes among people who have recovered from addiction. Objectives : In this study, posttraumatic growth in individuals who were formerly addicted to alcohol or substances, termed 'addiction-related growth,' was examined. Addiction-related growth refers to the growth that an individual undergoes as a result of the addiction itself, and the recovery from the addiction. A successful recovery from addiction is associated with positive changes, particularly regarding spirituality and meaning-making, and the construct of addiction-related growth may explain why. Method : This cross-sectional study examined growth among 104 individuals who had recovered from addiction who were recruited from addiction treatment programmes, between February and July 2012. Questionnaires assessed demographics and substance abuse use and treatment, posttraumatic growth (PTGI); social support (Perceived Social Support Questionnaire); and help-seeking ( Willingness to Seek Help Scale ). Data was analysed using an analysis of variance (ANOVA), Pearson correlations, and multiple regression. Results : Results indicated that addiction-related growth is a phenomenon that accurately captures the positive changes experienced as a result of an individual's struggle with addiction and recovery. This growth was found to be associated with participation in 12-steps programmes, and to be predicted by levels of perceived social support. Conclusions : The results show that recovery from addiction is associated with addiction-related growth. These positive changes, along with the importance of communal social support, resemble the changes that take place as a result of processes described in 12-steps programmes.

To describe relationships between cumulative trauma, partner conflict and post-traumatic stress in African-American postpartum women. Cumulative trauma exposure estimates for women in the USA range from 51-69%. During pregnancy, most trauma research has focused on physical injury to the mother. Post-traumatic stress disorder (PTSD) is associated with trauma and more prevalent in African-American women than women of other groups. Knowledge about both the rate and impact of cumulative trauma on pregnancy may contribute to our understanding of women seeking prenatal care, and disparities in infant morbidity and mortality. This retrospective, correlational, cross-sectional study took place on postpartum units of two Detroit hospitals. Participants were 150 African-American women aged between 18-45 who had given birth. Mothers completed the Cumulative Trauma Scale, Conflict Tactics Scale, Clinician Administered Post-traumatic Stress Scale, Edinburgh Postnatal Depression Scale and a Demographic Data form. Descriptive statistics, correlations and multiple regressions were used for data analysis. All participants reported at least one traumatic event in their lifetime. Cumulative trauma and partner conflict predicted PTSD, with the trauma of a life-threatening event for a loved one reported by 60% of the sample. Nearly, one-fourth of the women screened were at risk for PTSD. Increased cumulative trauma, increased partner conflict and lower level of education were related to higher rates of PTSD symptoms. Both cumulative trauma and partner conflict in the past year predict PTSD. Reasoning was used most often for partner conflict resolution. The results of this study offer additional knowledge regarding relationships between cumulative trauma, partner conflict and PTSD in African-American women. Healthcare providers need to be sensitive to patient life-threatening events, personal failures, abuse and other types of trauma. Current evidence supports the need to assess for post-traumatic stress symptoms during pregnancy. © 2016 John Wiley & Sons Ltd.
Challenges in treating post-traumatic stress disorder and attachment trauma.
Allen, Jon G
2003-06-01
Treating women suffering from trauma poses significant challenges. The diagnostic prototype of post-traumatic stress disorder (PTSD) is based on single-event trauma, such as sexual assault in adulthood. Several effective cognitive- behavioral treatments for such traumas have been developed, although many treated patients continue to experience residual symptoms. Even more problematic is the complex developmental psychopathology stemming from a lifetime history of multiple traumas, often beginning with maltreatment in early attachment relationships. A history of attachment trauma undermines the development of capacities to regulate emotional distress and thereby complicates the treatment of acute trauma in adulthood. Such complex trauma requires a multifaceted treatment approach that must balance processing of traumatic memories with strategies to contain the intense emotions this processing evokes. Moreover, conducting such treatment places therapists at risk for secondary trauma such that trauma therapists also must process this stressful experience and implement strategies to regulate their own distress.

Recent research has found that individuals with posttraumatic stress disorder (PTSD) exhibit an impaired memory of fear extinction compounded by deficient functional activation of key nodes of the fear network including the amygdala, hippocampus, ventromedial prefrontal cortex (vmPFC) and dorsal anterior cingulate cortex (dACC). Research has shown these regions are sexually dimorphic and activate differentially in healthy men and women during fear learning tasks. To explore biological markers of sex differences following exposure to psychological trauma, we used a fear learning and extinction paradigm together with functional magnetic resonance imaging (fMRI) and skin conductance response (SCR) to assess 31 individuals with PTSD (18 women; 13 men) and 25 matched trauma-exposed healthy control subjects (13 women; 12 men). Whereas no sex differences appeared within the trauma-exposed healthy control group, both psychophysiological and neural activation patterns within the PTSD group indicated deficient recall of extinction memory among men and not among women. Men with PTSD exhibited increased activation in the left rostral dACC during extinction recall compared with women with PTSD. These findings highlight the importance of tracking sex differences in fear extinction when characterizing the underlying neurobiological mechanisms of PTSD psychopathology. PMID:24560771

To identify sources of race/ethnic differences related to post-traumatic stress disorder (PTSD), we compared trauma exposure, risk for PTSD among those exposed to trauma, and treatment-seeking among Whites, Blacks, Hispanics and Asians in the US general population. Data from structured diagnostic interviews with 34 653 adult respondents to the 2004-2005 wave of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) were analysed. The lifetime prevalence of PTSD was highest among Blacks (8.7%), intermediate among Hispanics and Whites (7.0% and 7.4%) and lowest among Asians (4.0%). Differences in risk for trauma varied by type of event. Whites were more likely than the other groups to have any trauma, to learn of a trauma to someone close, and to learn of an unexpected death, but Blacks and Hispanics had higher risk of child maltreatment, chiefly witnessing domestic violence, and Asians, Black men, and Hispanic women had higher risk of war-related events than Whites. Among those exposed to trauma, PTSD risk was slightly higher among Blacks [adjusted odds ratio (aOR) 1.22] and lower among Asians (aOR 0.67) compared with Whites, after adjustment for characteristics of trauma exposure. All minority groups were less likely to seek treatment for PTSD than Whites (aOR range: 0.39-0.61), and fewer than half of minorities with PTSD sought treatment (range: 32.7-42.0%). When PTSD affects US race/ethnic minorities, it is usually untreated. Large disparities in treatment indicate a need for investment in accessible and culturally sensitive treatment options.

A 79-year-old woman suffered from acute posttraumatic stress disorder (PTSD) and a loco typico, non-displaced fracture of her right distal radius due to an incident involving the assault of two unleashed owned dogs, which suddenly ran into her and aggressively jumped on her chest and knocked her down to the ground. Recovery for her damage claim concerning pain and disability due to her right forearm fracture caused by the incident, was not the issue in the litigation concerned. However, the issue of delayed impact of her previous Holocaust experience placed a significant challenge on M.N., as a plaintiff, in establishing a causal link between the posttraumatic stress disorder concerned and the alleged harmful action of the defendants, the owners of the two dogs. The case reported here proved interesting and instructive not only in the sense of addressing main issues relevant to litigation for psychological damage related to reactivated PTSD and delayed PTSD, but also in the sense of pointing at the clinical relevance of dog assaults on humans which, even without dog bite injuries, may result in a severe traumatization and eventual civil lawsuit.

This study had two aims: 1. To examine whether soldiers who participated in Early Group Intervention (EGI) would show less distress and better functioning and physical health than soldiers who did not participate in EGI, and 2. To examine the contribution of the intervention to participants with repressive coping style. The sample comprised 166 male reserve soldiers who fought in the Second Lebanon War. The intervention was conducted three months after the traumatic event, was based on military protocol, and took place over the course of one day. Data were collected at two points in time (four months apart). The findings indicated that after EGI, the intervention group experienced less post-traumatic distress than did the control group. In addition, four months after the intervention, the functioning and physical health of the intervention group was significantly better than that of the control group. Notably, the intensity of post-traumatic distress before the intervention was lower among repressors and low-anxious soldiers than among soldiers in the other two groups (high-anxious and defensive). No significant differences were found after the intervention with regard to the various styles of coping with post-traumatic distress. Future clinical implications of the findings are discussed.

Germany is one of the most important host countries for minor refugees and asylum seekers in Europe. The number of children who leave their home country has significantly risen worldwide in recent years; a further rise is to be expected due to the increasing number of crisis zones. A literature review demonstrates the state of research on traumatization, post-traumatic stress disorders and psychotherapy in minor refugees and asylum seekers. Many minor refugees and asylum seekers have made mainly interpersonal traumatic experiences within their home country or during their flight and develop simple or complex post-traumatic stress disorders. Left untreated, there is a risk of chronification. The psychotherapeutic treatment of minor refugees and asylum seekers in Germany takes place primarily in specialized psychosocial treatment centers. For an involvement of therapists in private practices, a reduction of organizational barriers as well as evidence-based treatment methods for interpreter-aided psychotherapy of minor refugees and asylum seekers that also consider their developmental state, are still lacking. In research, as well as in practice, there is further need for an early and systematic identification and treatment of minor refugees and asylum seekers with post-traumatic stress disorders or high risk of disease in Germany.

The current study presents a pilot demonstration of a new therapeutic procedure to mitigate symptoms of post-traumatic stress disorder (PTSD). The pilot took place during the Second Lebanon War. Vulnerability and resilience statements, as well as post-traumatic symptoms, were measured among special army administrative staff (SAAS) who worked in a hospital setting during extreme and prolonged war stress. All 13 soldiers in the unit studied participated in seven group therapy intervention sessions. It was hypothesized that shifting the focus of therapeutic intervention from the scenes of the events to the personal and professional narratives of preparing for the event would change the content of the soldiers' narratives. It was believed that subtracting the number of positive statements from the number of negative statements would yield increasingly higher "resilience scores" during and after the war. It also was believed that such a change would be reflected in reduction of post-traumatic symptoms. As expected, the participants showed a decrease in vulnerability and an increase in resilience contents, as well as a decrease in traumatic symptoms during and after the war. These findings may reflect the effects of the ceasefire, the mutually supportive attitude of the participants, and the therapeutic interventions.
Nociceptin and the nociceptin receptor in learning and memory.
Andero, Raül
2015-10-01
There are many processes in which the neuropeptide nociceptin/orphanin FQ (N/OFQ or nociceptin) is involved in the brain. The role of nociceptin in learning and memory holds promise in modulating these processes in health and disease in the human brain. This review summarizes the body of research focused on N/OFQ and its specific receptor, the nociceptin receptor (NOP receptor), in learning and memory, and its potential mechanisms of action, in which acetylcholine, NMDA receptor, and noradrenaline may be critical. Finally, the association between NOP receptor and posttraumatic stress disorder (PTSD), a psychiatric disorder with altered fear learning, is examined as one of the potential outcomes resulting from pathological consequences of dysregulation of N/OFQ-NOP receptor in the brain.

Breast cancer, potentially a traumatic stressor, may be accompanied by negative outcomes, such as posttraumatic stress disorder or positive changes, such as posttraumatic growth. The authors reviewed 24 studies published from 1990 to 2010 that measured posttraumatic stress disorder and posttraumatic growth in women with breast cancer, in terms of frequency rates, factors associated with posttraumatic stress disorder and posttraumatic growth, and their interrelationships. A relatively small percentage of women experienced posttraumatic stress disorder, while the majority of them reported posttraumatic growth. Age, education, economic status, subjective appraisal of the threat of the disease, treatment, support from significant others, and positive coping strategies were among the most frequently reported factors associated with these phenomena. Moreover, posttraumatic stress disorder and posttraumatic growth were not related. Future research should shed more light on posttraumatic growth and posttraumatic stress disorder among women with breast cancer, the parameters that influence them, and their possible relationship.

These days, college students study not only at places designed for learning such as libraries in colleges, but also cafes in downtown while the number of facilities for learning run by colleges is increasing. Then I have researched facilities in college and those in downtown to find selective properties of college students’ learning space. First, I found by questionnaire survey that students chose “3rd place” such as cafes and fast food shops, second to their houses and libraries in college. Next, I found “psychological factor” were also affected their choice. Furthermore, they studied different subjects at different places. In experiments, I researched how effectively they studied each subject at every place. The results show that I find that places you like and places where learning efficiency is good are different. They learned the least effective at “3d place” regardless of what they learned. The result of how long they kept high-level intellectual activity at each place shows that they could work on the study with more motivation at their favorite place and 3rd place. On the other hand, at the 2nd place, they could study rather effectively, but could not keep concentration and motivation for a long time. In this way, college students have 2 patterns of choosing learning space.

Posttraumatic Growth and Dyadic Adjustment among War Veterans and their Wives
Lahav, Yael; Kanat-Maymon, Yaniv; Solomon, Zahava
2017-01-01
The controversy regarding the nature of posttraumatic growth includes two main competing claims: one which argues that posttraumatic growth reflects authentic positive changes and the other which argues that posttraumatic growth reflects illusory defenses. While the former might suggest that posttraumatic growth enhances intimacy and close relationships, the latter might imply that posttraumatic growth hinders interpersonal relations. The present study aimed to test these claims by investigating the association between posttraumatic growth and dyadic adjustment over time at both the individual and dyadic levels, and the potential role of posttraumatic stress symptoms. Former prisoners of war and comparable war veterans and their wives (n = 229) were assessed twice, 30–31 (T1) and 35–38 (T2) years after the 1973 Yom Kippur War in Israel, with regard to posttraumatic growth, posttraumatic stress symptoms and dyadic adjustment. Results indicated that posttraumatic growth was associated with both elevated posttraumatic stress symptoms and low dyadic adjustment among both husbands and wives. Posttraumatic stress symptoms at T1 and T2 mediated the association between posttraumatic growth and dyadic adjustment. Wives' posttraumatic growth at T1 predicted posttraumatic growth and dyadic adjustment of the husbands at T2. The higher the wives' posttraumatic growth, the higher the posttraumatic growth and the lower the dyadic adjustment of the husbands in the subsequent measure. The findings suggest that posttraumatic growth reflects defensive beliefs which undermine marital relationships and that posttraumatic growth might be transmitted between spouses and implicated in the deterioration of the marital relationship over time.

Sex differences in learned fear expression and extinction involve the medial prefrontal cortex (mPFC). We recently demonstrated that enhanced learned fear expression during auditory fear extinction and its recall is linked to persistent theta activation in the prelimbic (PL) but not infralimbic (IL) cortex of female rats. Emerging evidence indicates that gamma oscillations in mPFC are also implicated in the expression and extinction of learned fear. Therefore we re-examined our in vivo electrophysiology data and found that females showed persistent PL gamma activation during extinction and a failure of IL gamma activation during extinction recall. Altered prefrontal gamma oscillations thus accompany sex differences in learned fear expression and its extinction. These findings are relevant for understanding the neural basis of post-traumatic stress disorder, which is more prevalent in women and involves impaired extinction and mPFC dysfunction.

To date, studies of biological risk factors have revealed inconsistent relationships with subsequent post-traumatic stress disorder (PTSD). The inconsistent signal may reflect the use of data analytic tools that are ill equipped for modeling the complex interactions between biological and environmental factors that underlay post-traumatic psychopathology. Further, using symptom-based diagnostic status as the group outcome overlooks the inherent heterogeneity of PTSD, potentially contributing to failures to replicate. To examine the potential yield of novel analytic tools, we reanalyzed data from a large longitudinal study of individuals identified following trauma in the general emergency room (ER) that failed to find a linear association between cortisol response to traumatic events and subsequent PTSD. First, latent growth mixture modeling empirically identified trajectories of post-traumatic symptoms, which then were used as the study outcome. Next, support vector machines with feature selection identified sets of features with stable predictive accuracy and built robust classifiers of trajectory membership (area under the receiver operator characteristic curve (AUC)=0.82 (95% confidence interval (CI)=0.80–0.85)) that combined clinical, neuroendocrine, psychophysiological and demographic information. Finally, graph induction algorithms revealed a unique path from childhood trauma via lower cortisol during ER admission, to non-remitting PTSD. Traditional general linear modeling methods then confirmed the newly revealed association, thereby delineating a specific target population for early endocrine interventions. Advanced computational approaches offer innovative ways for uncovering clinically significant, non-shared biological signals in heterogeneous samples. PMID:28323285

This study aimed to assess the level of posttraumatic stress disorder and to examine the relationship between exposure to war stress and posttraumatic symptoms among health care providers following Israeli offensives against Gaza Strip in 2014. A cross-sectional design was used for this study. We targeted all nurses and doctors working in three governmental hospitals in the Gaza Strip and worked with victims of the last war, more specifically, those who were working in emergency departments, intensive care units, operating rooms, surgical departments, and burn units. A demographic sheet and Impact Event Scale-Revised were used in this study. The Impact Event Scale-Revised has three sub-scales; intrusion, avoidance, and hyper-arousal. The results showed that 291 (89.8%) of 324 participants had scores more than 35 (threshold cut-off point) on the Impact Event Scale-Revised. Scores ranged from zero to 80 with a mean of 52.13. Females had higher levels of stress (55.79) than males (51.63) and nurses (54.85) had more stress than physicians (47.38). The most frequent symptoms of trauma subscales was "avoidance" (mean=20.04), followed by "intrusion" (mean=17.83), and then "hyper-arousal" (mean=14.27). Levels of trauma symptoms were not affected by place of living, hospital of work, while level of education had impacted level of trauma. The findings showed that health care providers suffered from severe posttraumatic symptoms after exposure to prolonged war stress. This level of trauma among health care providers warrants intervention programs to reduce stress and trauma among Gaza health care providers after the war. Copyright © 2015 Elsevier Inc.

Within one month (March 2001), two separate incidents of school shootings occurred at two different high schools within the same school district in San Diego's East County. To examine community-wide expressions of post-traumatic distress resulting from the shootings that may or may not fulfill DSM-IV criteria for post-traumatic stress disorder (PTSD), but which might interfere with treatment and the prevention of youth violence. A qualitative study was undertaken using Rapid Assessment Procedures (RAP) in four East San Diego County communities over a six-month period following the two events. Semi-structured interviews were conducted with 85 community residents identified through a maximum variation sampling technique. Interview transcripts were analyzed by coding consensus, co-occurrence, and comparison, using text analysis software. Three community-wide patterns of response to the two events were identified: (1) 52.9% of respondents reported intrusive reminders of the trauma associated with intense media coverage and subsequent rumors, hoaxes, and threats of additional acts of school violence; (2) 44.7% reported efforts to avoid thoughts, feelings, conversations, or places (i.e., schools) associated with the events; negative assessment of media coverage; and belief that such events in general cannot be prevented; and (3) 30.6% reported anger, hyper-vigilance, and other forms of increased arousal. Twenty-three (27.1%) respondents reported symptoms of fear, anxiety, depression, drug use, and psychosomatic symptoms in themselves or others. School shootings can precipitate symptoms of post-traumatic stress disorder at the community level. Such symptoms hinder the treatment of individuals with PTSD and the implementation of effective prevention strategies and programs.

Treatment of posttraumatic stress symptoms and facilitation of posttraumatic growth are two encouraging areas of research, yet little is understood about the relationships between trait mindfulness, posttraumatic stress symptoms, and posttraumatic growth. Previous work suggests the linkages among these variables, but most studies have been conducted in adult samples. The aim of this study was to examine longitudinal cross-lagged relationships between mindfulness, posttraumatic stress symptoms, and posttraumatic growth among adolescent survivors of the 2016 Jiangsu tornado in China. Data was collected at two secondary schools located in Yancheng city, where the severe catastrophic damage occurred during the tornado. The sample included 247 adolescent survivors (59.5% girls) aged 12-14 years who were directly affected by the tornado. Participants self-reported their trait mindfulness, posttraumatic stress symptoms, and posttraumatic growth at two time points: 6-month (T1) and 9-month post-tornado (T2; attrition rate 17.4%). Cross-lagged structural equation modelling analyses were conducted. Results showed that posttraumatic stress symptoms at T1 significantly predicted reduced trait mindfulness at T2 but not posttraumatic growth; trait mindfulness at T1 did not significantly predict posttraumatic stress symptoms nor posttraumatic growth at T2; and posttraumatic growth at T1 did not predict trait mindfulness nor posttraumatic stress symptoms at T2. These findings suggested that posttraumatic stress symptoms may negatively influence the development of trait mindfulness in disaster-affected adolescents in China, and that posttraumatic growth may have unique implications for this young population which was not associated with posttraumatic stress symptoms or trait mindfulness.

Deficits in fear extinction learning are hypothesized to underlie the development of posttraumatic stress disorder (PTSD). Such deficits may, in part, be due to genetic and epigenetic variation in the stress related gene FKBP5. Conversely, altering FKBP5 epigenetic responses during memory consolidation may rescue extinction deficits making it a target for acute intervention to prevent the development of PTSD. Study 1 (Humans) examines if FKBP5 single nucleotide polymorphisms (SNPs) and PTSD symptom domains (re-experiencing, avoidance/numbing, hyperarousal) are associated with abnormal fear extinction phenotypes identified using latent growth mixture modeling (LGMM). Study 2 (Mice) tests if increasing doses of dexamethasone administered prior to extinction alters Fkbp5 mRNA production in the amygdala after extinction and recall and prevents the development of abnormal extinction phenotypes. In humans, abnormal extinction was associated with the TT homozygous genotype of FKBP5 SNPs RS9470080 and RS1360780, and hyperarousal symptoms. In mice, dexamethasone 300 μg/kg was associated with increased amygdala Fkbp5 mRNA following extinction and robust extinction learning while lower doses were not associated with amygdala Fkbp5 mRNA or differences in extinction learning. Further, mice that extinguished on dexamethasone 300 μg/kg maintained low levels of freezing behavior during recall training while mRNA levels were no longer elevated. Together, findings indicate that FKBP5 confers risk for fear extinction deficits. However, this risk may be ameliorated by increasing fkbp5 mRNA expression in the amygdala during memory consolidation making this mechanism a plausible point of acute intervention to prevent the development of PTSD.

Patients' narratives about traumatic experiences and symptoms are useful in clinical screening and diagnostic procedures. In this study, we presented an automated assessment system to screen patients for posttraumatic stress disorder via a natural language processing and text-mining approach. Four machine-learning algorithms-including decision tree, naive Bayes, support vector machine, and an alternative classification approach called the product score model-were used in combination with n-gram representation models to identify patterns between verbal features in self-narratives and psychiatric diagnoses. With our sample, the product score model with unigrams attained the highest prediction accuracy when compared with practitioners' diagnoses. The addition of multigrams contributed most to balancing the metrics of sensitivity and specificity. This article also demonstrates that text mining is a promising approach for analyzing patients' self-expression behavior, thus helping clinicians identify potential patients from an early stage.

Virtual-reality (VR) therapy has been distinguished from other psychotherapy interventions through the use of computer-assisted interventions that rely on the concepts of "immersion," "presence," and "synchrony." In this work, these concepts are defined, and their uses, within the VR treatment architecture, are discussed. VR therapy's emphasis on the incorporation of biofeedback and meditation, as a component of the VR treatment architecture, is also reviewed. A growing body of research has documented VR therapy as a successful treatment for combat-related Posttraumatic Stress Disorder (PTSD). The VR treatment architecture, utilized to treat 30 warriors diagnosed with combat-related PTSD, is summarized. Lastly, case summaries of two warriors successfully treated with VR therapy are included to assist with the goal of better understanding a VR treatment architecture paradigm. Continued validation of the VR treatment model is encouraged.
Implications of memory modulation for post-traumatic stress and fear disorders
Parsons, Ryan G; Ressler, Kerry J
2013-01-01
Post-traumatic stress disorder, panic disorder and phobia manifest in ways that are consistent with an uncontrollable state of fear. Their development involves heredity, previous sensitizing experiences, association of aversive events with previous neutral stimuli, and inability to inhibit or extinguish fear after it is chronic and disabling. We highlight recent progress in fear learning and memory, differential susceptibility to disorders of fear, and how these findings are being applied to the understanding, treatment and possible prevention of fear disorders. Promising advances are being translated from basic science to the clinic, including approaches to distinguish risk versus resilience before trauma exposure, methods to interfere with fear development during memory consolidation after a trauma, and techniques to inhibit fear reconsolidation and to enhance extinction of chronic fear. It is hoped that this new knowledge will translate to more successful, neuroscientifically informed and rationally designed approaches to disorders of fear regulation. PMID:23354388

Improved efficacy in the treatment of posttraumatic stress disorder (PTSD) and other anxiety disorders is urgently needed. Traditional anxiety treatments of hypnosis and psychodynamic therapy may be of some help, but uncontrolled studies lead to inconclusive results on the efficacy of these treatment techniques. There is a larger literature supporting the efficacy of cognitive-behavioral procedures with PTSD, including prolonged exposure therapy, eye movement desensitization and reprocessing, and anxiety management techniques. The cutting-edge technology of virtual reality-based exposure therapy for PTSD is particularly exciting. To further build on effective psychosocial treatments, current pharmacological augmentation approaches to emotional learning are being combined with psychotherapy. In particular, D-cycloserine, a partial NMDA agonist, has shown to be effective in facilitating the exposure/extinction therapy to improve the efficacy of treating anxiety disorders, and may guide the way for new pharmacological enhancements of behavioral therapy.

The aim of this study was to examine the relationships among extraversion, social support, posttraumatic stress disorder and posttraumatic growth among adolescent survivors of the Wenchuan earthquake. Six hundred thirty-eight participants were selected from the survivors of the 2008 Wenchuan earthquake. Participants completed four main questionnaires, including the Extraversion Subscale, the Social Support Scale, the Child PTSD Symptom Scale, and the Posttraumatic Growth Inventory. A bivariate correlation analysis revealed significant correlations among extraversion, social support, posttraumatic stress disorder and posttraumatic growth. Extraversion had significant indirect effects on posttraumatic stress disorder (β = -.037, p < .01) and posttraumatic growth (β = .077, p < .001) through social support. The results also indicated that extraversion had a significant direct effect on posttraumatic growth and a nonsignificant direct effect on posttraumatic stress disorder. Social support fully mediates the relationship between extraversion and posttraumatic stress disorder and partially mediates the relationship between extraversion and posttraumatic growth. Psychological interventions and care for survivors of the earthquake should include the various functions and sources of social support and how they serve to benefit individuals.

This study aimed to determine the efficacy of silicone gel (Cica-Care) on severe post-traumatic hypertophic scars among the Chinese population. A randomized clinical trial (RCT) was conducted on 45 Chinese patients with post-traumatic hypertrophic scars. Twenty-two subjects were placed in the experimental group with silicone gel sheeting (SGS) applied 24h per day for 6 months while all subjects were taught to massage the scar daily for 15 min serving as the control intervention. Scar assessments were conducted regularly to measure the changes in thickness, pigmentation, vascularity, pliability, itchiness and pain. Two-way repeated ANOVA showed a significant difference between MT group and SGS group on scar thickness. The post hoc comparison analysis showed that the difference was significant at the post-2-month (p=0.008) and post-6-month (p<0.001) intervention. The SGS group also showed changes in pigmentation which resembled normal skin but no statistical significance was found. Pain, itchiness and pliability were also improved after intervention. This study indicated that silicone gel sheeting (Cica-Care) was effective to reduce thickness, pain, itchiness and pliability of the severe hypertrophic scar among the Chinese population. The moisturization effect of the tough and hard scar might contribute to the reduction of the skin thickness after 6 month's intervention.

The effect of indirect (versus direct) exposure to a traumatic event on the quality of life of terrorist attack victims has received considerable attention in the literature. However, more research is required to examine whether the symptoms and underlying processes caused by both types of exposure are equivalent. Our main hypothesis is that well-being plays a different role depending on indirect vs. direct trauma exposure. In this cross-sectional study, eighty direct victims of 11-M terrorist attacks (people who were traveling in trains where bombs were placed) and two-hundred indirect victims (individuals highly exposed to the 11-M terrorist attacks through communications media) voluntarily participated without compensation. To test our hypothesis regarding the mediating role of indirect exposure, we conducted a biased corrected bootstrapping procedure. To test our hypothesis regarding the moderating role of direct exposure, data were subjected to a hierarchical regression analysis. As predicted, for indirect trauma exposure, well-being mediated the relationship between post-traumatic dysfunctional cognitions and trauma symptoms. However, for direct trauma exposure, well-being moderated the relationship between post-traumatic dysfunctional cognitions and trauma symptoms. The results of our study indicate that the different role of well-being found between indirect (causal factor) and direct exposure (protective factor) should be taken into consideration in interventions designed to improve victims' health.

Recent research has found that individuals with posttraumatic stress disorder (PTSD) exhibit an impaired memory of fear extinction compounded by deficient functional activation of key nodes of the fear network including the amygdala, hippocampus, ventromedial prefrontal cortex (vmPFC) and dorsal anterior cingulate cortex (dACC). Research has shown these regions are sexually dimorphic and activate differentially in healthy men and women during fear learning tasks. To explore biological markers of sex differences following exposure to psychological trauma, we used a fear learning and extinction paradigm together with functional magnetic resonance imaging (fMRI) and skin conductance response (SCR) to assess 31 individuals with PTSD (18 women; 13 men) and 25 matched trauma-exposed healthy control subjects (13 women; 12 men). Whereas no sex differences appeared within the trauma-exposed healthy control group, both psychophysiological and neural activation patterns within the PTSD group indicated deficient recall of extinction memory among men and not among women. Men with PTSD exhibited increased activation in the left rostral dACC during extinction recall compared with women with PTSD. These findings highlight the importance of tracking sex differences in fear extinction when characterizing the underlying neurobiological mechanisms of PTSD psychopathology.

A proposed explanation for memory impairments in posttraumatic stress disorder (PTSD) is stress-induced hippocampal damage due to elevated cortisol levels. We have previously reported smaller hippocampi in police officers with PTSD. In this study, we examined changes in and associations between cortisol, learning, memory, attention, and hippocampal volume in PTSD. In a case-matched control study, 12 police officers with PTSD and 12 traumatized police officers without lifetime PTSD were examined with magnetic resonance imaging (for hippocampal volume), salivary cortisol tests, and neurocognitive assessments. Significantly smaller hippocampi and higher early morning salivary cortisol levels were found in PTSD. Subjects with PTSD performed worse on a delayed visual memory recall task at trend level, and made more perseverations and intrusions on a verbal memory task. Negative correlations were found between PTSD symptom severity and immediate recall function, and between re-experiencing symptoms and left hippocampal volume. A positive correlation was found between salivary cortisol level in early morning and right hippocampal volume; however, hippocampal volume did not correlate with memory. Smaller hippocampi, higher cortisol levels, and memory impairments were associated with PTSD but were not directly correlated to one another. Memory impairments in PTSD do not seem to be a direct consequence of hippocampal size.

Globally, female sex workers (FSW) experience a high prevalence of mental health disorders, but in sub-Saharan Africa these are rarely identified. If left untreated, mental health disorders may place FSW and their partners at risk for HIV/sexually transmitted infections (STIs). We assessed the prevalence and correlates of probable depression, post-traumatic stress disorder (PTSD), and suicidal ideation (SI) in a cohort of 200 FSW in Lilongwe, Malawi. FSW completed the Patient Health Questionnaire-9 and the PTSD Check List-Civilian Version. The prevalence of depression was 8%, as was the prevalence of PTSD. Nearly half (49%) of FSW were experiencing mild depression. FSW were more likely to have probable depression if they completed primary school or initiated sex work before 18 years. They were more likely to have probable PTSD if they had ≥ 20 clients per week or initiated sex work before 18 years. Interventions are needed to diagnose mental health disorders among FSW at great risk for HIV/STIs.
The relationships between trait anxiety, place recognition memory, and learning strategy.

Rodents learn to navigate mazes using various strategies that are governed by specific regions of the brain. The type of strategy used when learning to navigate a spatial environment is moderated by a number of factors including emotional states. Heightened anxiety states, induced by exposure to stressors or administration of anxiogenic agents, have been found to bias male rats toward the use of a striatum-based stimulus-response strategy rather than a hippocampus-based place strategy. However, no study has yet examined the relationship between natural anxiety levels, or trait anxiety, and the type of learning strategy used by rats on a dual-solution task. In the current experiment, levels of inherent anxiety were measured in an open field and compared to performance on two separate cognitive tasks, a Y-maze task that assessed place recognition memory, and a visible platform water maze task that assessed learning strategy. Results indicated that place recognition memory on the Y-maze correlated with the use of place learning strategy on the water maze. Furthermore, lower levels of trait anxiety correlated positively with better place recognition memory and with the preferred use of place learning strategy. Therefore, competency in place memory and bias in place strategy are linked to the levels of inherent anxiety in male rats. Copyright © 2010 Elsevier B.V. All rights reserved.

There is growing evidence that fear-learning abnormalities are involved in the development of posttraumatic stress disorder (PTSD) and chronic pain. More than 50% of PTSD patients suffer from chronic pain. This study aimed to examine the role of fear-learning deficits in the link between pain perception and PTSD. We included 19 subjects with PTSD and 21 age- and sex-matched healthy control subjects in a fear-conditioning experiment. The conditioned stimulus (CS) consisted of visual signs flashed upon a screen in front of each subject. The unconditioned stimulus was either a low or high temperature impulse delivered through a thermal contact thermode on the subjects' hand. A designation of 'CS-' was assigned to CS always followed by nonpainful low-temperature stimuli; a designation of 'CS+' was given to CS that were randomly followed by either a low or a more painful high temperature. Skin conductance was used as a physiological marker of fear. In healthy control subjects, CS+ induced more fear than CS-, and a low-temperature stimulus induced less subjective pain after CS- than after CS+. PTSD subjects failed to demonstrate such adaptive conditioning. Fear ratings after CS presentation were significantly higher in the PTSD group than in the control group. There were significant interaction effects between group and the type of CS on fear and pain ratings. Fear-learning deficits are a potentially promising, specific psychopathological factor in altered pain perception associated with PTSD. Deficits in safety learning may increase fear and, consequently, pain sensations. These findings may contribute to elucidating the pathogenesis behind the highly prevalent comorbidity that exists between PTSD and pain disorders, and to developing new treatments. This study provides new insights into the pathogenesis of chronic pain in patients with PTSD. The findings may help to develop new treatment strategies for this highly prevalent comorbidity in PTSD.

Increasing plasticity in neurons of the prefrontal cortex (PFC) has been proposed as a possible therapeutic tool to enhance extinction, a process that is impaired in post-traumatic stress disorder, schizophrenia, and addiction. To test this hypothesis, we generated transgenic mice that overexpress neurogranin (a calmodulin-binding protein that facilitates long-term potentiation) in the PFC. Neurogranin overexpression in the PFC enhanced long-term potentiation and increased the rates of extinction learning of both fear conditioning and sucrose self-administration. Our results indicate that elevated neurogranin function within the PFC can enhance local plasticity and increase the rate of extinction learning across different behavioral tasks. Thus, neurogranin can provide a molecular link between enhanced plasticity and enhanced extinction. Copyright © 2015 the authors 0270-6474/15/357503-06$15.00/0.

Throughout the past several decades, studies have uncovered a wealth of information about the neural circuitry underlying fear learning and extinction that has helped to inform treatments for fear-related disorders such as post-traumatic stress and anxiety. Yet, up to 40 percent of people do not respond to such treatments. Adolescence, in particular, is a developmental stage during which anxiety disorders peak, yet little is known about the development of fear-related neural circuitry during this period. Moreover, pharmacological and behavioral therapies that have been developed are based on mature circuitry and function. Here, we review neural circuitry implicated in fear learning and data from adolescent mouse and human fear learning studies. In addition, we propose a developmental model of fear neural circuitry that may optimize current treatments and inform when, during development, specific treatments for anxiety may be most effective.

Multimodal approach to identifying malingered posttraumatic stress disorder: a review.
Ali, Shahid; Jabeen, Shagufta; Alam, Farzana
2015-01-01
The primary aim of this article is to aid clinicians in differentiating true posttraumatic stress disorder from malingered posttraumatic stress disorder. Posttraumatic stress disorder and malingering are defined, and prevalence rates are explored. Similarities and differences in diagnostic criteria between the fourth and fifth editions of the Diagnostic and Statistical Manual of Mental Disorders are described for posttraumatic stress disorder. Possible motivations for malingering posttraumatic stress disorder are discussed, and common characteristics of malingered posttraumatic stress disorder are described. A multimodal approach is described for evaluating posttraumatic stress disorder, including interview techniques, collection of collateral data, and psychometric and physiologic testing, that should allow clinicians to distinguish between those patients who are truly suffering from posttraumatic disorder and those who are malingering the illness.

Family presence at resuscitation attempts.
Jaques, Helen
UK resuscitation guidelines suggest that parents and carers should be allowed to be present during a resuscitation attempt in hospital but no guidance is available regarding family presence when resuscitation takes place out of hospital. A new research study has suggested that relatives who were offered the opportunity to witness resuscitation were less likely to develop symptoms of post-traumatic stress disorder than those who were not given the chance. This article summarises the results of this study and provides an expert commentary on its conclusions.

Sense of Coherence (SOC) and mindfulness are known protective factors against psychopathology, also in older age. We set out to investigate the influence of SOC and mindfulness on posttraumatic symptoms and cognitions in the context of lifetime trauma in elderly persons with a history of childhood war-experiences. Elderly Austrians (N = 97) filled in questionnaires on traumatic lifetime experiences and posttraumatic symptoms (ETI), posttraumatic cognitions (PTCI), SOC (SOC-13) and mindfulness (FFMQ). We expected the influence of SOC scores on posttraumatic symptoms and cognitions to be on one hand influenced by mindfulness. On the other hand, we expected that both aspects would uniquely explain fewer posttraumatic symptoms and cognitions. Participants reported various lifetime traumas (M = 2.42), including experiences during World War II (WWII) as children and adolescents. Mindfulness partially mediated the association of SOC scores with posttraumatic cognitions, but not with posttraumatic symptoms. However, in a two-stage mediation model, mindfulness significantly predicted posttraumatic symptoms via its effects on posttraumatic cognitions. Although SOC was the strongest predictor of posttraumatic symptoms, mindfulness influenced the severity of posttraumatic symptoms via its effects on posttraumatic cognitions. We discuss implications for mindfulness-based interventions on trauma-related cognitions in the elderly.
Correlates of posttraumatic growth in survivors of intimate partner violence.
Cobb, Amanda R; Tedeschi, Richard G; Calhoun, Lawrence G; Cann, Arnie
2006-12-01
The negative consequences of intimate partner violence are well documented. This study investigated the possibility that some survivors of intimate partner violence may also experience posttraumatic growth because of their struggle with this highly stressful circumstance. In addition, the relationships between posttraumatic growth and relationship status, type of abuse, depression, and availability of models of posttraumatic growth were examined. Most women reported posttraumatic growth. Overall abuse experienced and depression were unrelated to posttraumatic growth, but abuse was related to one domain of growth. Contact with a model of posttraumatic growth and having left an abusive relationship were both positively related to posttraumatic growth.

Individual differences after trauma vary considerably and can range from posttraumatic stress disorder (PTSD) to posttraumatic growth (PTG). Current theoretical models cannot fully explain this variability. Therefore, we integrated attachment theory with Ehlers and Clark's model of PTSD to understand whether attachment style is associated with negative appraisals of a traumatic event(s), posttraumatic stress symptoms (PTS), and PTG. Our aim was to test this integrated model PTSD in an analog sample who had experienced at least one traumatic event. We used structural equation modeling to test the association of adult attachment and posttraumatic cognitions (self and world/others) with PTS and PTG using a cross-sectional, correlational design. The sample comprised 393 university staff and students (RangeAge= 18-49, 85% females) who completed online measures. Attachment anxiety and negative posttraumatic self-cognitions were positively associated. Negative posttraumatic self-cognitions were positively associated with PTS. Attachment anxiety had an indirect effect (via negative posttraumatic self-cognitions) on PTS, whereas attachment avoidance predicted more negative posttraumatic world cognitions and lower perceived PTG. The study highlights the importance of considering how attachment styles influence posttraumatic emotion regulation and cognitive processing of the trauma to determine posttraumatic mental health.

Experiencing potentially traumatic events is associated with psychological distress. However, some survivors also experience positive personal and psychological changes in the aftermath of trauma. The present study investigated perceived posttraumatic growth in 197 ministerial employees who were present at work during the 2011 Oslo bombing attack. The relationships between trauma-exposure, peritraumatic reactions and posttraumatic growth were studied. Moreover, the adaptive significance of posttraumatic growth was addressed. The results showed that higher levels of trauma-exposure and immediate reactions were significantly related to perceived posttraumatic growth. No support for an adaptive significance of posttraumatic growth was found. On the contrary, posttraumatic growth was associated with higher symptom levels of posttraumatic stress. After adjusting for posttraumatic stress symptoms no association was found between perceived growth and work and social adjustment. However, perceived growth was associated with higher levels of life satisfaction. The present results are in line with previous findings indicating that perceived growth may be unrelated to psychological adjustment, and suggest that the concept and significance of posttraumatic growth should be interpreted with caution.

Informal caregivers-that is, close family and friends providing unpaid emotional or instrumental care-of patients admitted to ICUs are at risk for posttraumatic stress disorder. As a first step toward developing interventions to prevent posttraumatic stress disorder in ICU caregivers, we examined the predictive validity of psychosocial risk screening during admission for caregiver posttraumatic stress disorder at 3 and 6 months post hospitalization. An observational, prospective study. Ninety-nine caregivers were recruited as part of a longitudinal research program of patient-caregiver dyads in a neuroscience ICU. None. Caregiver posttraumatic stress disorder symptoms were assessed during admission (baseline), 3 months, and 6 months post hospitalization. We 1) characterized prevalence of clinically significant symptoms at each time point 2); calculated sensitivity and specificity of baseline posttraumatic stress disorder screening in predicting posttraumatic stress disorder at 3 and 6 months; and 3) used recursive partitioning to select potential baseline factors and examine the extent to which they helped predict clinically significant posttraumatic stress disorder symptoms at each time point. Rates of caregiver posttraumatic stress disorder remained relatively stable over time (16-22%). Screening for posttraumatic stress disorder at baseline predicted posttraumatic stress disorder at 3 and 6 months with moderate sensitivity (75-80%) and high specificity (92-95%). Screening for posttraumatic stress disorder at baseline was associated with caregiver anxiety, mindfulness (i.e., ability to be aware of one's thoughts and feelings in the moment), and bond with patient. Furthermore, baseline posttraumatic stress disorder screening was the single most relevant predictor of posttraumatic stress disorder at 3 and 6 months, such that other baseline factors did not significantly improve predictive ability. Screening neuroscience ICU caregivers for clinically significant posttraumatic stress disorder symptoms during admission is the single most important way to identify the majority of those likely to suffer from chronic posttraumatic stress disorder following discharge. Addressing early posttraumatic stress disorder symptoms and their psychosocial correlates during admission may help prevent chronic posttraumatic stress disorder in these at-risk caregivers.
Memory modification as an outcome variable in anxiety disorder treatment.
Tryon, Warren W; McKay, Dean
2009-05-01
Learning and memory are interdependent processes. Memories are learned, and cumulative learning requires memory. It is generally accepted that learning contributes to psychopathology and consequently to pertinent memory formation. Neuroscience and psychological research have established that memory is an active reconstructive process that is influenced by thoughts, feelings, and behaviors including post-event information. Recent research on the treatment of anxiety disorders using medications (i.e., d-cyclcloserine) to alter neurological systems associated with memory used in conjunction with behavior therapy suggests that memory is part of a central mechanism in the etiology and maintenance of these conditions. The main thesis of this article is that learning-based interventions create new memories that may modify existing ones. This raises the possibility of using such memory modifications to measure intervention outcome. A connectionist context for understanding this phenomenon and informing intervention is provided, with specific reference to post-traumatic stress disorder, obsessive-compulsive disorder, and generalized anxiety disorder. Recommendations for future research examining the role of memory change in treatment outcome are suggested.

There has been a great deal of recent interest in human models of contextual fear learning, particularly due to the use of such paradigms for investigating neural mechanisms related to the etiology of posttraumatic stress disorder. However, the construct of "context" in fear conditioning research is broad, and the operational definitions and methods used to investigate contextual fear learning in humans are wide ranging and lack specificity, making it difficult to interpret findings about neural activity. Here we will review neuroimaging studies of contextual fear acquisition in humans. We will discuss the methodology associated with four broad categories of how contextual fear learning is manipulated in imaging studies (colored backgrounds, static picture backgrounds, virtual reality, and configural stimuli) and highlight findings for the primary neural circuitry involved in each paradigm. Additionally, we will offer methodological recommendations for human studies of contextual fear acquisition, including using stimuli that distinguish configural learning from discrete cue associations and clarifying how context is experimentally operationalized.

Middle school students in Lushan county (N = 315) were assessed 6 months after the Yaan earthquake using a trauma severity questionnaire, a posttraumatic fear questionnaire, a social support questionnaire and a posttraumatic growth inventory to examine the effects of posttraumatic fear and social support in the relationship between trauma severity and posttraumatic growth (PTG). The results showed that posttraumatic fear mediated the relationship between trauma severity and PTG, and social support moderated the relationship between posttraumatic fear and PTG. These findings suggested that trauma severity could be positively associated with PTG in a direct way or in an indirect way through posttraumatic fear. Moreover, posttraumatic fear had a positive relation to PTG under the condition of high social support level, whereas the relation was non-significant when the level of social support was low. These results were discussed in terms of their implications for adolescents after trauma. © 2016 International Union of Psychological Science.
Preliminary evidence for a unique role of disgust-based conditioning in posttraumatic stress.
Badour, Christal L; Feldner, Matthew T; Blumenthal, Heidemarie; Knapp, Ashley
2013-04-01
Independent lines of evidence have linked posttraumatic stress symptomatology to both peritraumatic disgust (i.e., disgust experienced during a traumatic event) and posttraumatic disgust reactivity in response to traumatic event cues among individuals exposed to traumatic events. Much of this work suggests disgust, defined as a rejection/revulsion response aimed at distancing oneself from a potential source of contamination, may be important in understanding the nature of posttraumatic stress reactions even after accounting for the more frequently studied affective states of fear and anxiety. The current investigation provided a preliminary test of a model of disgust in posttraumatic stress among a sample of 54 community-recruited women with a history sexual victimization. Both peritraumatic disgust (r = .31) and posttraumatic disgust reactivity (r = .42) in response to an idiographic traumatic event script were significantly associated with posttraumatic stress symptom severity. After accounting for variability-associated peritraumatic fear and posttraumatic anxious reactivity, an indirect effect of peritraumatic disgust through posttraumatic disgust reactivity also was found, suggesting that one mechanism through which peritraumatic disgust relates to posttraumatic stress is through its relation with increased posttraumatic disgust reactivity. These findings highlight the importance of further elucidating the nature of disgust in relation to traumatic events and subsequent posttraumatic stress reactions.

Academics move a lot. In this autoethnographic essay, I explore aspects of mobility, rootedness, mindfulness, and learning though my own story of leaving a place I loved for a new place I was drawn to, a place where I have begun the long and uncertain process of building new relationships of attachment. We lead mobile lives, even as we learn to appreciate the benefits of staying put to both people and land. Between rootedness and mobility lives a rich tension, termed "place-based transience". What do the experience of place and transience imply for our work as academics, as mindful human beings in the process of learning and becoming? The essay probes this question and concludes with a series of haiku—as an example of a particular "practice of place" I've found helpful for connecting me to my new homeplace, even as I question whether I'll stick around.

Stress induces a shift from hippocampus-based "cognitive" toward dorsal striatum-based "habitual" learning and memory. This shift is thought to have important implications for stress-related psychopathologies, including post-traumatic stress disorder (PTSD). However, there is large individual variability in the stress-induced bias toward habit memory, and the factors underlying this variability are completely unknown. Here we hypothesized that a functional deletion variant of the gene encoding the α2b-adrenoceptor ( ADRA2B ), which has been linked to emotional memory processes and increased PTSD risk, modulates the stress-induced shift from cognitive toward habit memory. In two independent experimental studies, healthy humans were genotyped for the ADRA2B deletion variant. After a stress or control manipulation, participants completed a dual-solution learning task while electroencephalographic (Study I) or fMRI measurements (Study II) were taken. Carriers compared with noncarriers of the ADRA2B deletion variant exhibited a significantly reduced bias toward habit memory after stress. fMRI results indicated that, whereas noncarriers of the ADRA2B deletion variant showed increased functional connectivity between amygdala and putamen after stress, this increase in connectivity was absent in carriers of the deletion variant, who instead showed overall enhanced connectivity between amygdala and entorhinal cortex. Our results indicate that a common genetic variation of the noradrenergic system modulates the impact of stress on the balance between cognitive and habitual memory systems, most likely via altered amygdala orchestration of these systems. SIGNIFICANCE STATEMENT Stressful events have a powerful effect on human learning and memory. Specifically, accumulating evidence suggests that stress favors more rigid dorsal striatum-dependent habit memory, at the expense of flexible hippocampus-dependent cognitive memory. Although this shift may have important implications for understanding mental disorders, such as post-traumatic stress disorder, little is known about the source of individual differences in the sensitivity for the stress-induced bias toward habit memory. We report here that a common genetic variation of the noradrenergic system, a known risk factor for post-traumatic stress disorder, modulates the stress-induced shift from cognitive to habit memory, most likely through altered crosstalk between the hippocampus and dorsal striatum with the amygdala, a key structure in emotional memory.

Aim To examine how the experience of genocide in Srebrenica in the early childhood (ages 1-5) influences the psychological health in adolescence. Methods This study included 100 school-attending adolescents, age 15-16 (born in 1990-91) who were divided in two groups according to the place of residence from 1992-1995: the Srebrenica group – adolescents who lived in Srebrenica during the siege and the non-Srebrenica group who lived in the “free territory,” were not wounded, and experienced no losses. We used the socio-demographic questionnaire created for the purposes of our study and the War Trauma Questionnaire, Posttraumatic Stress Reactions Questionnaire, Self-report Depressive Scale (Zung), Freiburg Personality Inventory, and the Lifestyle Questionnaire. Results Srebrenica adolescents experienced significantly more traumatic experiences (14.26 ± 3.11 vs 4.86 ± 3.16, P < 0.001). Although there was no significant difference in the total score of posttraumatic stress reactions and intensity of depression between the two groups, significantly higher scores of posttraumatic stress reaction were noticed for several specific questions. The most prominent defense mechanisms in both groups were projection, intellectualization, and reactive formation. Srebrenica adolescents had higher sociability levels (34.7% vs 16.0%, χ2 = 7.231, P = 0.020). Conclusion Srebrenica adolescents reported significantly more severe PTSD symptoms and significantly greater sociability. Our findings could be used for planning treatment and improving communication and overcoming traumas in war-affected areas. PMID:23444247
Sex differences in fear discrimination do not manifest as differences in conditioned inhibition.

Distinguishing safety from danger is necessary for survival, but is aberrant in individuals with post-traumatic stress disorder (PTSD). While PTSD is more prevalent in women than men, research on sex differences in safety learning is limited. Here, female rats demonstrated greater fear discrimination than males in a CS+/CS- paradigm. To determine if this sex difference transferred to fear inhibition, rats were tested for conditioned inhibition in a summation test with the CS+ and CS- presented in compound; no sex difference emerged. The results suggest sex differences in the neural mechanisms of discrimination learning but not recall of a fear inhibitor. © 2018 Foilb et al.; Published by Cold Spring Harbor Laboratory Press.

To explore the roles of attachment and alexithymia in the severity of post-traumatic stress disorder symptoms and to specify the relationship between sub-dimensions of attachment, alexithymia and posttraumatic stress disorder symptoms in patients with first-time myocardial infarction in mainland China. Patients experiencing myocardial infarction have a risk of developing post-traumatic stress disorder symptoms. However, there have been few studies on the roles of attachment and alexithymia. A cross-sectional survey design. Ninety-seven patients participated in the assessment of post-traumatic stress disorder symptoms, attachment and alexithymia from June-December in 2012. To assess post-traumatic stress disorder symptoms and their correlates, we administered the Post-traumatic Stress Disorder Checklist-Civilian Version, the 20-item Toronto Alexithymia Scale and the Experiences in Close Relationships Scale 5-17 days after the remission of first myocardial infarction attack. Twenty-five (25·77%) patients met the criteria of posttraumatic stress disorder symptoms. Greater attachment anxiety and avoidance were associated with more severe posttraumatic stress disorder symptoms. Except for externally oriented thinking, all dimensions of alexithymia were significantly correlated with post-traumatic stress symptoms. In the regression model, attachment anxiety and difficulties identifying feelings were found to be predictive and the total regression equation explained 24·2% variance of posttraumatic stress disorder symptoms among myocardial infarction patients. First-time myocardial infarction patients were at risk of developing posttraumatic stress disorder symptoms. Attachment anxiety and difficulties identifying feelings were positively associated with posttraumatic stress disorder symptoms in the early stage of myocardial infarction rehabilitation. It is essential to evaluate the causal relationship between attachment, alexithymia and posttraumatic stress disorder symptoms in longitudinal studies. © 2015 John Wiley & Sons Ltd.
Effects of cortisol suppression on sleep-associated consolidation of neutral and emotional memory.
Wagner, Ullrich; Degirmenci, Metin; Drosopoulos, Spyridon; Perras, Boris; Born, Jan
2005-12-01
Previous research indicates that hippocampus-dependent declarative memory benefits from early nocturnal sleep, when slow-wave sleep (SWS) prevails and cortisol release is minimal, whereas amygdala-dependent emotional memory is enhanced through late sleep, when rapid eye movement (REM) sleep predominates. The role of the strong cortisol rise accompanying late sleep for emotional memory consolidation has not yet been investigated. Effects of the cortisol synthesis inhibitor metyrapone on sleep-associated consolidation of memory for neutral and emotional texts were investigated in a randomized, double-blind, placebo-controlled study in 14 healthy men. Learning took place immediately before treatment, which was followed by 8 hours of sleep. Retrieval was tested at 11 am the next morning. Metyrapone suppressed cortisol during sleep and blocked particularly the late-night rise in cortisol. It reduced SWS and concomitantly impaired the consolidation of neutral texts. Emotional texts were spared from this impairing influence, however. Metyrapone even amplified emotional enhancement in text recall indicating amygdala-dependent memory. Cortisol blockade during sleep impairs hippocampus-dependent declarative memory formation but enhances amygdala-dependent emotional memory formation. The natural cortisol rise during late sleep may thus protect from overshooting emotional memory formation, a mechanism possibly pertinent to the development of posttraumatic stress disorder.

Exposure to the trauma memory is the common denominator of most evidence-based interventions for posttraumatic stress disorder (PTSD). Although exposure-based therapies aim to change associative learning networks and negative cognitions related to the trauma memory, emotional interactions between patient and therapist have not been thoroughly considered in past evaluations of exposure-based therapy. This work focuses on recent discoveries of the mirror-neuron system and the theory of embodied simulation (ES). These conceptualizations may add a new perspective to our understanding of change processes in exposure-based treatments for PTSD patients. It is proposed that during exposure to trauma memories, emotional responses of the patient are transferred to the therapist through ES and then mirrored back to the patient in a modulated way. This process helps to alleviate the patient's sense of loneliness and enhances his or her ability to exert control over painful, trauma-related emotional responses. ES processes may enhance the integration of clinical insights originating in psychoanalytic theories—such as holding, containment, projective identification, and emotional attunement—with cognitive behavioral theories of learning processes in the alleviation of painful emotional responses aroused by trauma memories. These processes are demonstrated through a clinical vignette from an exposure-based therapy with a trauma survivor. Possible clinical implications for the importance of face-to-face relationships during exposure-based therapy are discussed. PMID:26593097

Study Objectives: One-third of deployed military personnel will be diagnosed with insomnia, placing them at high risk for comorbid depression, posttraumatic stress disorder (PTSD), and medical conditions. The disruption of trophic factors has been implicated in these comorbid conditions, which can impede postdeployment recovery. This study determined if improved sleep quality is associated with (1) reductions in depression and posttraumatic symptoms, as well as enrichments in health-related quality of life (HRQOL), and (2) changes in plasma concentrations of brain derived neurotrophic factor (BDNF) and insulin-like growth factor-1 (IGF-1). Methods: Forty-four military personnel diagnosed with insomnia underwent clinical evaluations and blood draws at pretreatment and at posttreatment following cognitive behavioral therapy for insomnia and automatic positive airway pressure treatment. Participants were classified as sleep improved (n = 28) or sleep declined (n = 16) based on their change in pretreatment to posttreatment Pittsburgh Sleep Quality Index (PSQI) score. Both groups were compared on outcomes of depression, PTSD, HRQOL, BDNF, and IGF-1. Results: Paired t-tests of the sleep improved group revealed significant declines in depression (p = 0.005) and posttraumatic arousal (p = 0.006) symptoms, and a significant increase in concentrations of IGF-1 (p = 0.009). The sleep declined group had no relevant change in psychiatric symptoms or trophic factors, and had further declines on five of eight dimensions of HRQOL. Between-group change score differences were significant at p < 0.05. Conclusions: These findings suggest that interventions, which successfully improve sleep quality, are an effective means to reduce the depression and posttraumatic arousal symptoms common to military personnel, as well as increase protective trophic factors implicated in these conditions.

Context Processing and the Neurobiology of Post-Traumatic Stress Disorder
Liberzon, Israel; Abelson, James L.
2016-01-01
Summary Progress in clinical and affective neuroscience is redefining psychiatric illness as symptomatic expression of cellular/molecular dysfunctions in specific brain circuits. Post-traumatic stress disorder (PTSD) has been an exemplar of this progress, with improved understanding of neurobiological systems subserving fear learning, salience detection, and emotion regulation explaining much of its phenomenology and neurobiology. However, many features remain unexplained and a parsimonious model that more fully accounts for symptoms and the core neurobiology remains elusive. Contextual processing is a key modulatory function of hippocampal-prefrontal-thalamic circuitry, allowing organisms to disambiguate cues and derive situation-specific meaning from the world. We propose that dysregulation within this context-processing circuit is at the core of PTSD pathophysiology, accounting for much of its phenomenology and most of its biological findings. Understanding core mechanisms like this, and their underlying neural circuits, will sharpen diagnostic precision and understanding of risk factors, enhancing our ability to develop preventive and “personalized” interventions.

Posttraumatic stress disorder (PTSD) is characterized by hyperarousal, flashbacks, avoidance, and memory dysfunctions. Although psychotherapy improves the clinical symptoms, its effect on memory has not been explored. In addition, there is no information about gene expression changes related to hippocampal functions. We assessed PTSD patients (n=20) using the Wechsler Memory Scale-Revised (WAIS-R) and a paired associates learning (PAL) test, as well as changes in blood FK506 binding protein (FKBP5) mRNA expression before and after cognitive behavioral therapy (CBT). Results revealed that before CBT PTSD patients were impaired on WAIS-R delayed recall, attention/concentration, and PAL compared with trauma-exposed control subjects (n=20). These memory dysfunctions showed a significant improvement after CBT. Better performance on the PAL test correlated with enhanced blood FKBP5 mRNA expression. These results suggest that elevated FKBP5 expression during CBT is related to improved associative memory linked to the hippocampal formation. Copyright © 2014 Elsevier Ireland Ltd.

Grief, traumatic stress, and posttraumatic growth in women who have experienced pregnancy loss.
Krosch, Daniel Jay; Shakespeare-Finch, Jane
2017-07-01
Pregnancy loss is common and can be devastating for those who experience it. However, a historical focus on negative outcomes, and grief in particular, has rendered an incomplete portrait of both the gravity of the loss, and the potential for growth in its wake. Consistent with contemporary models of growth following bereavement, this study explored the occurrence of posttraumatic growth following pregnancy loss and further assessed the role of core belief disruptions and common loss context factors across perinatal grief, posttraumatic stress symptoms, and posttraumatic growth. Women who had experienced a miscarriage or stillbirth (N = 328) were recruited through perinatal loss support groups and completed an online survey that assessed core belief disruption, perinatal grief, posttraumatic stress symptoms, posttraumatic growth, loss context factors, and demographics. Hypotheses were tested via hierarchical multiple regression. All hypotheses were supported. Specifically, (a) moderate levels of posttraumatic growth were reported; (b) core belief disruptions predicted perinatal grief, posttraumatic stress symptoms, and posttraumatic growth; and (c) perinatal grief predicted posttraumatic stress symptoms and growth. Findings suggest that pregnancy loss can be a traumatic event, that core belief disruptions play a significant role in posttrauma outcomes, and that other factors may contribute to grief, posttraumatic stress symptoms, and posttraumatic growth following pregnancy loss that warrant further research (e.g., rumination). Despite potential methodological and sampling limitations, the use of validated measures to assess posttraumatic growth in a large sample represents a robust attempt to quantify the occurrence of posttrauma change following pregnancy loss.

Women at pre partum and post partum are especially susceptible to war trauma because they struggle to protect their infants from danger. Trauma research suggests increased problems in maternal mental health and infant development. Yet many cognitive-emotional processes affect the trauma survivors' mental health, such as post-traumatic growth and post-traumatic cognition. The aim of this study was to examine whether a mother's high post-traumatic growth and optimal post-traumatic cognition could protect their own mental health and their infant's stress regulation from the effects of traumatic war experiences. This three-wave prospective study involved Palestinian women living in the Gaza Strip who were at the second trimester of pregnancy (T1), women with infants aged 4 months (T2), and women with children aged 12 months (T3) months. The participants reported their war experiences in a 30-item checklist of losses, destruction, and atrocities in the 2008-09, 2012, and 2014 military offensives. Post-traumatic growth was assessed by a 21-item scale and post-traumatic cognition by a 36-item scale. Maternal mental health was assessed by post-traumatic stress disorder (PTSD), depressive, anxiety, and dissociation symptoms at T1 and T3, and infants' stress regulation was assessed with the Infant Behaviour Questionnaire at T2 and T3. We included 511 women at T1, 481 women at T2, and 454 women at T3. High maternal post-traumatic growth and post-traumatic cognition had protective roles. Post-traumatic growth had a protective effect on maternal mental health since severe exposure to traumatic war experiences was not associated with maternal PTSD, depression, and dissociation if women showed high post-traumatic growth, as indicated by the significant interaction effect between post-traumatic growth and war trauma on each of the three symptoms. Post-traumatic cognition had a protective effect on infant development since severe exposure was not associated with dysfunctional infant emotion regulation when mothers reported optimal post-traumatic cognition, as indicated by the significant interaction effect between post-traumatic cognition and war trauma on each of negative affectivity and surgency or extraversion. The nature of cognitive emotional processing of war trauma could explain the distinct roles of post-traumatic growth and post-traumatic cognition. High post-traumatic growth involves increased social affiliation, spiritual awareness, and psychological strengths resulting from painful and traumatic experiences. In the national struggle for independence, post-traumatic growth is often associated with heroism and even hardiness, which might benefit a mother's mental health but not their infant's wellbeing. Optimal post-traumatic cognition indicates successful and harmonious trauma processing, which enables mothers to be more reflective and sensitive to their infant's needs. Interventions to promote healthy infant development in war settings should encourage and support mothers' effective cognitive-emotional processing of traumatic experiences.

Endogenous estrogens have bidirectional effects on learning and memory, enhancing or impairing cognition depending on many variables, including the task and the memory systems that are engaged. Moderate increases in estradiol enhance hippocampus-sensitive place learning, yet impair response learning that taps dorsal striatum function. This memory modulation likely occurs via activation of estrogen receptors, resulting in altered neural function. Supplements containing estrogenic compounds from plants are widely consumed despite limited information about their effects on brain function, including learning and memory. Phytoestrogens can enter the brain and signal through estrogen receptors to affect cognition. Enhancements in spatial memory and impairments in executive function have been found following treatment with soy phytoestrogens, but no tests of actions on striatum-sensitive tasks have been made to date. The present study compared the effects of acute exposure to the isoflavone genistein with the effects of estradiol on performance in place and response learning tasks. Long-Evans rats were ovariectomized, treated with 17β-estradiol benzoate, genistein-containing sucrose pellets, or vehicle (oil or plain sucrose pellets) for two days prior to behavioral training. Compared to vehicle controls, estradiol treatment enhanced place learning at a low (4.5 μg/kg) but not high dose (45 μg/kg), indicating an inverted pattern of spatial memory facilitation. Treatment with 4.4 mg of genistein over two days also significantly enhanced place learning over vehicle controls. For the response task, treatment with estradiol impaired learning at both the low and high doses; likewise, genistein treatment impaired response learning compared to rats receiving vehicle. Overall, genistein was found to mimic estradiol-induced shifts in place and response learning, facilitating hippocampus-sensitive learning and slowing striatum-sensitive learning. These results suggest signaling through estrogen receptor β and membrane-associated estrogen receptors in learning enhancements and impairments given the preferential binding of genistein to the ERβ subtype and affinity for GPER.

Near-Death Experiences and Posttraumatic Growth.
Khanna, Surbhi; Greyson, Bruce
2015-10-01
Posttraumatic growth denotes positive psychological change after a traumatic experience that is an improvement over the state before the trauma. Inasmuch as it involves existential reevaluation, posttraumatic growth overlaps with spiritual change, although it also encompasses other domains of positive outcome. This study investigated posttraumatic growth and presence and depth of near-death experience at the time of the close brush with death among 251 survivors of a close brush with death, using the Posttraumatic Growth Inventory and the Near-Death Experience (NDE) Scale. Near-death experiences were associated with greater posttraumatic growth than were close brushes with death in the absence of such an experience, and scores on the NDE Scale were significantly correlated with scores on the Posttraumatic Growth Inventory. To the extent that NDEs are interpreted as spiritual events, these findings support prior research suggesting that spiritual factors make a significant contribution to posttraumatic growth and are consistent with the model that posits challenges to the assumptive worldview as a major stimulus to posttraumatic growth.

The effects of biological sex and gonadal hormones on learning strategy in adult rats.
Hawley, Wayne R; Grissom, Elin M; Barratt, Harriet E; Conrad, Taylor S; Dohanich, Gary P
2012-02-28
When learning to navigate toward a goal in a spatial environment, rodents employ distinct learning strategies that are governed by specific regions of the brain. In the early stages of learning, adult male rats prefer a hippocampus-dependent place strategy over a striatum-dependent response strategy. Alternatively, female rats exhibit a preference for a place strategy only when circulating levels of estradiol are elevated. Notably, male rodents typically perform better than females on a variety of spatial learning tasks, which are mediated by the hippocampus. However, limited research has been done to determine if the previously reported male spatial advantage corresponds with a greater reliance on a place strategy, and, if the male preference for a place strategy is impacted by removal of testicular hormones. A dual-solution water T-maze task, which can be solved by adopting either a place or a response strategy, was employed to determine the effects of biological sex and hormonal status on learning strategy. In the first experiment, male rats made more correct arm choices than female rats during training and exhibited a bias for a place strategy on a probe trial. The results of the second experiment indicated that testicular hormones modulated arm choice accuracy during training, but not the preference for a place strategy. Together, these findings suggest that the previously reported male spatial advantage is associated with a greater reliance on a place strategy, and that only performance during the training phase of a dual-solution learning task is impacted by removal of testicular hormones.

Background Psychiatric outpatients with a refugee background have often been exposed to a variety of potentially traumatizing events, with numerous negative consequences for their mental health and quality of life. However, some patients also report positive personal changes, posttraumatic growth, related to these potentially traumatic events. This study describes posttraumatic growth, posttraumatic stress symptoms, depressive symptoms, post-migration stressors, and their association with quality of life in an outpatient psychiatric population with a refugee background in Norway. Methods Fifty five psychiatric outpatients with a refugee background participated in a cross-sectional study using clinical interviews to measure psychopathology (SCID-PTSD, MINI), and four self-report instruments measuring posttraumatic growth, posttraumatic stress symptoms, depressive symptoms, and quality of life (PTGI-SF, IES-R, HSCL-25-depression scale, and WHOQOL-Bref) as well as measures of social integration, social network and employment status. Results All patients reported some degree of posttraumatic growth, while only 31% reported greater amounts of growth. Eighty percent of the patients had posttraumatic stress symptoms above the cut-off point, and 93% reported clinical levels of depressive symptoms. Quality of life in the four domains of the WHOQOL-Bref levels were low, well below the threshold for the’life satisfaction’ standard proposed by Cummins. A hierarchic regression model including depressive symptoms, posttraumatic stress symptoms, posttraumatic growth, and unemployment explained 56% of the total variance found in the psychological health domain of the WHOQOL-Bref scale. Posttraumatic growth made the strongest contribution to the model, greater than posttraumatic stress symptoms or depressive symptoms. Post-migration stressors like unemployment, weak social network and poor social integration were moderately negatively correlated with posttraumatic growth and quality of life, and positively correlated with psychopathological symptoms. Sixty percent of the outpatients were unemployed. Conclusions Multi-traumatized refugees in outpatient clinics reported both symptoms of psychopathology and posttraumatic growth after exposure to multiple traumatic events. Symptoms of psychopathology were negatively related to the quality of life, and positively related to post-migration stressors such as unemployment, weak social network and poor social integration. Posttraumatic growth was positively associated with quality of life, and negatively associated with post-migration stressors. Hierarchical regression modeling showed that posttraumatic growth explained more of the variance in quality of life than did posttraumatic stress symptoms, depressive symptoms or unemployment. It may therefore be necessary to address both positive changes and psychopathological symptoms when assessing and treating multi-traumatized outpatients with a refugee background. PMID:22824521

Reactivated memories can be modified during reconsolidation, making this process a potential therapeutic target for posttraumatic stress disorder (PTSD), a mental illness characterized by the recurring avoidance of situations that evoke trauma-related fears. However, avoidance memory reconsolidation depends on a set of still loosely defined boundary conditions, limiting the translational value of basic research. In particular, the involvement of the hippocampus in fear-motivated avoidance memory reconsolidation remains controversial. Combining behavioral and electrophysiological analyses in male Wistar rats, we found that previous learning of relevant nonaversive information is essential to elicit the participation of the hippocampus in avoidance memory reconsolidation, which is associated with an increase in theta- and gamma-oscillation power and cross-frequency coupling in dorsal CA1 during reactivation of the avoidance response. Our results indicate that the hippocampus is involved in memory reconsolidation only when reactivation results in contradictory representations regarding the consequences of avoidance and suggest that robust nesting of hippocampal theta-gamma rhythms at the time of retrieval is a specific reconsolidation marker. SIGNIFICANCE STATEMENT Posttraumatic stress disorder (PTSD) is characterized by maladaptive avoidance responses to stimuli or behaviors that represent or bear resemblance to some aspect of a traumatic experience. Disruption of reconsolidation, the process by which reactivated memories become susceptible to modifications, is a promising approach for treating PTSD patients. However, much of what is known about fear-motivated avoidance memory reconsolidation derives from studies based on fear conditioning instead of avoidance-learning paradigms. Using a step-down inhibitory avoidance task in rats, we found that the hippocampus is involved in memory reconsolidation only when the animals acquired the avoidance response in an environment that they had previously learned as safe and showed that increased theta- and gamma-oscillation coupling during reactivation is an electrophysiological signature of this process.

Studies employing brain lesion or intracerebral drug infusions in rats have demonstrated a double dissociation between the roles of the hippocampus and dorsolateral striatum in place and response learning. The hippocampus mediates a rapid cognitive learning process underlying place learning, whereas the dorsolateral striatum mediates a relatively slower learning process in which stimulus-response habits underlying response learning are acquired in an incremental fashion. One potential implication of these findings is that hippocampus-dependent learning may benefit from a relative massing of training trials, whereas dorsal striatum-dependent learning may benefit from a relative distribution of training trials. In order to examine this hypothesis, the present study compared the effects of massed (30s inter-trial interval; ITI) or spaced (30min ITI) training on acquisition of a hippocampus-dependent place learning task, and a dorsolateral striatum-dependent response task in a plus-maze. In the place task rats swam from varying start points (N or S) to a hidden escape platform located in a consistent spatial location (W). In the response task rats swam from varying start points (N or S) to a hidden escape platform located in the maze arm consistent with a body-turn response (left). In the place task, rats trained with the massed trial schedule acquired the task quicker than rats trained with the spaced trial schedule. In the response task, rats trained with the spaced trial schedule acquired the task quicker than rats trained with the massed trial schedule. The double dissociation observed suggests that the reinforcement parameters most conducive to effective learning in hippocampus-dependent and dorsolateral striatum-dependent learning may have differential temporal characteristics.

Fear-based disorders, like social anxiety disorder (SAD) and posttraumatic stress disorder (PTSD), are characterized by an exaggerated fear response and avoidance to trigger cues, suggesting a transdiagnostic mechanism of psychopathology. Current theories suggest that abnormalities in conditioned fear is a primary contributor to the pathophysiology of these disorders. The primary goal of this study was to compare acquisition of conditioned stimulus (CS) and aversive unconditioned stimulus (US) contingencies during fear learning and extinction in individuals with SAD and PTSD. In a standard Pavlovian fear conditioning-extinction paradigm we measured subjective US expectancy ratings to different CSs in patients with SAD (n=16) compared to patients with PTSD (n=13) and healthy controls (n=15) RESULTS: Both patient groups (SAD, PTSD) acquired differential conditioning between a CS that predicted US (CS+) and a CS that never predicted the US (CS-), however, both groups reported an increased expectancy that the US would occur following the CS-. Additionally, the PTSD group overestimated that the US would occur in general. Neither patient group showed evidence of successful extinction of the CS+-US contingency nor differentiated their expectation of US occurrence between the CS+ and CS- during extinction learning. Group sample sizes were small and we did not include a trauma-exposed group without PTSD CONCLUSIONS: Both SAD and PTSD generalize expectations of an aversive outcome across CSs, even when a CS never signals an aversive outcome and PTSD may tend to over-expect threat. Fear learning and extinction abnormalities may be a core feature underlying shared symptoms across fear-based disorders. Copyright © 2016 Elsevier B.V. All rights reserved.

Posttraumatic stress disorder (PTSD) is associated with regional alterations in brain structure and function that are hypothesized to contribute to symptoms and cognitive deficits associated with the disorder. We present here the first systematic meta-analysis of neurocognitive outcomes associated with PTSD to examine a broad range of cognitive domains and describe the profile of cognitive deficits, as well as modifying clinical factors and study characteristics. This report is based on data from 60 studies totaling 4,108 participants, including 1,779with PTSD, 1,446 trauma-exposed comparison participants, and 895 healthy comparison participants without trauma exposure. Effect size estimates were calculated using a mixed-effects meta-analysis for nine cognitive domains: attention/working memory, executive functions, verbal learning, verbal memory, visual learning, visual memory, language, speed of information processing, and visuospatial abilities. Analyses revealed significant neurocognitive effects associated with PTSD, although these ranged widely in magnitude, with the largest effect sizes in verbal learning (d =−.62), speed of information processing (d =−.59), attention/working memory (d =−.50), and verbal memory (d =−.46). Effect size estimates were significantly larger in treatment-seeking than community samples and in studies that did not exclude participants with attention-deficit hyperactivity disorder, and effect sizes were affected by between-group IQ discrepancies and the gender composition of the PTSD groups. Our findings indicate that consideration of neuropsychological functioning in attention, verbal memory, and speed of information processing may have important implications for the effective clinical management of persons with PTSD. Results are further discussed in the context of cognitive models of PTSD and the limitations of this literature. PMID:25365762
Intrusive Images in Psychological Disorders
Brewin, Chris R.; Gregory, James D.; Lipton, Michelle; Burgess, Neil
2010-01-01
Involuntary images and visual memories are prominent in many types of psychopathology. Patients with posttraumatic stress disorder, other anxiety disorders, depression, eating disorders, and psychosis frequently report repeated visual intrusions corresponding to a small number of real or imaginary events, usually extremely vivid, detailed, and with highly distressing content. Both memory and imagery appear to rely on common networks involving medial prefrontal regions, posterior regions in the medial and lateral parietal cortices, the lateral temporal cortex, and the medial temporal lobe. Evidence from cognitive psychology and neuroscience implies distinct neural bases to abstract, flexible, contextualized representations (C-reps) and to inflexible, sensory-bound representations (S-reps). We revise our previous dual representation theory of posttraumatic stress disorder to place it within a neural systems model of healthy memory and imagery. The revised model is used to explain how the different types of distressing visual intrusions associated with clinical disorders arise, in terms of the need for correct interaction between the neural systems supporting S-reps and C-reps via visuospatial working memory. Finally, we discuss the treatment implications of the new model and relate it to existing forms of psychological therapy. PMID:20063969

Research studies have defined the important role of endogenous opioids in modulating stress-associated behavior. The release of β-endorphins in the amygdala in response to stress helps to cope with a stressor by inhibiting the over-activation of HPA axis. Administration of mu opioid agonists reduces the risk of developing post-traumatic stress disorder (PTSD) following a traumatic event by inhibiting fear-related memory consolidation. Similarly, the release of endogenous enkephalin and nociceptin in the basolateral amygdala and the nucleus accumbens tends to produce the anti-stress effects. An increase in dynorphin levels during prolonged exposure to stress may produce learned helplessness, dysphoria and depression. Stress also influences morphine-induced conditioned place preference (CPP) depending upon the intensity and duration of the stressor. Acute stress inhibits morphine CPP, while chronic stress potentiates CPP. The development of dysphoria due to increased dynorphin levels may contribute to chronic stress-induced potentiation of morphine CPP. The activation of ERK/cyclic AMP responsive element-binding (CREB) signaling in the mesocorticolimbic area, glucocorticoid receptors in the basolateral amygdala, and norepinephrine and galanin system in the nucleus accumbens may decrease the acute stress-induced inhibition of morphine CPP. The increase in dopamine levels in the nucleus accumbens and augmentation of GABAergic transmission in the median prefrontal cortex may contribute in potentiating morphine CPP. Stress exposure reinstates the extinct morphine CPP by activating the orexin receptors in the nucleus accumbens, decreasing the oxytocin levels in the lateral septum and amygdala, and altering the GABAergic transmission (activation of GABAA and inactivation of GABAB receptors). The present review describes these varied interactions between opioids and stress along with the possible mechanism. Copyright © 2015 Elsevier Ltd. All rights reserved.

Abstract Background Posttraumatic stress disorder is characterized by an overactive noradrenergic system conferring core posttraumatic stress disorder symptoms such as hyperarousal and reexperiencing. Monoamine oxidase A is one of the key enzymes mediating the turnover of noradrenaline. Here, DNA methylation of the monoamine oxidase A gene exonI/intronI region was investigated for the first time regarding its role in posttraumatic stress disorder risk and severity. Methods Monoamine oxidase A methylation was analyzed via direct sequencing of sodium bisulfite-treated DNA extracted from blood cells in a total sample of N=652 (441 male) patients with current posttraumatic stress disorder, patients with remitted posttraumatic stress disorder, and healthy probands (comparison group) recruited at 5 centers in Bosnia-Herzegovina, Croatia, and the Republic of Kosovo. Posttraumatic stress disorder severity was measured by means of the Clinician-Administered Posttraumatic Stress Disorder Scale and its respective subscores representing distinct symptom clusters. Results In the male, but not the female sample, patients with current posttraumatic stress disorder displayed hypermethylation of 3 CpGs (CpG3=43656362; CpG12=43656514; CpG13=43656553, GRCh38.p2 Assembly) as compared with remitted Posttraumatic Stress Disorder patients and healthy probands. Symptom severity (Clinician-Administered Posttraumatic Stress Disorder Scale scores) in male patients with current posttraumatic stress disorder significantly correlated with monoamine oxidase A methylation. This applied particularly to symptom clusters related to reexperiencing of trauma (cluster B) and hyperarousal (cluster D). Conclusions The present findings suggest monoamine oxidase A gene hypermethylation, potentially resulting in enhanced noradrenergic signalling, as a disease status and severity marker of current posttraumatic stress disorder in males. If replicated, monoamine oxidase A hypermethylation might serve as a surrogate marker of a hyperadrenergic subtype of posttraumatic stress disorder guiding personalized treatment decisions on the use of antiadrenergic agents.

If replicated, monoamine oxidase A hypermethylation might serve as a surrogate marker of a hyperadrenergic subtype of posttraumatic stress disorder guiding personalized treatment decisions on the use of antiadrenergic agents.

Changes in world assumptions are a fundamental concept within theories that explain posttraumatic stress disorder. The objective of the present study was to gain a greater understanding of how changes in world assumptions are related to quality of life and posttraumatic stress symptoms after a natural disaster. A longitudinal study of 574 Norwegian adults who survived the Southeast Asian tsunami in 2004 was undertaken. Multilevel analyses were used to identify which factors at six months post-tsunami predicted quality of life and posttraumatic stress symptoms two years post-tsunami. Good quality of life and posttraumatic stress symptoms were negatively related. However, major differences in the predictors of these outcomes were found. Females reported significantly higher quality of life and more posttraumatic stress than men. The association between level of exposure to the tsunami and quality of life seemed to be mediated by posttraumatic stress. Negative perceived changes in the assumption "the world is just" were related to adverse outcome in both quality of life and posttraumatic stress. Positive perceived changes in the assumptions "life is meaningful" and "feeling that I am a valuable human" were associated with higher levels of quality of life but not with posttraumatic stress. Quality of life and posttraumatic stress symptoms demonstrate differences in their etiology. World assumptions may be less specifically related to posttraumatic stress than has been postulated in some cognitive theories.

The purpose of this study was to evaluate posttraumatic growth among breast cancer patients and their significant others over a 1(1/2)-year time span after diagnosis and to examine cognitive and emotional processes in posttraumatic growth. One hundred sixty-two women with breast cancer and their partners completed surveys assessing posttraumatic growth, cognitive and emotional processing, and marital satisfaction at 3 time points spaced 9 months apart. Posttraumatic growth increased for both partners during this period. Patient posttraumatic growth was predicted by younger age, contemplating reasons for cancer, and more emotional expression at time 1. Partner posttraumatic growth was predicted by younger age, more intrusive thoughts, and greater use of positive reappraisal and emotional processing at time 1. Posttraumatic growth is reported by patients and by significant others. Cognitive and emotional processes predict growth. Patient growth is associated with the significant other's cognitive and emotional processing of breast cancer.

Understanding place, including both the environment and its people, is essential to understanding our climate, climate change, and its impacts. For us to develop a sense of our place, we need to engage in multiple ways of learning: observation, experimentation, and opportunities to apply new knowledge (Orr, 1992). This approach allows us to access different sources of knowledge and then create local solutions for local issues. It is especially powerful when we rely on experts and elders in our own community along with information from the global community.The Pacific islands Climate Education Partnership (PCEP) is a collaboration of partners—school systems, nongovernmental organizations, and government agencies—working to support learning and teaching about climate in the Pacific. Since 2009, PCEP partners have been working together to develop and implement classroom resources, curriculum standards, and teacher professional learning opportunities in which learners approach climate change and its impacts first through the lens of their own place. Such an approach to putting place central to teaching and learning about climate requires partnership and opportunities for learners to explore solutions for and with their communities. In this presentation, we will share the work unfolding in the Republic of the Marshall Islands (RMI) as one example of PCEP's approach to place-based climate education. Three weeklong K-12 teacher professional learning workshops took place during June-July 2015 in Majuro, RMI on learning gardens, climate science, and project-based learning. Each workshop was co-taught with local partners and supports educators in teaching climate-related curriculum standards through tasks that can foster sense of place through observation, experimentation, and application of new knowledge. Additionally, we will also share PCEP's next steps in place-based climate education, specifically around emerging conversations about the importance of highlighting stories of place to generate local solutions for local issues, as well as further global awareness about climate change impacts in the Pacific.

Symptoms of post-traumatic stress disorder are common in fibromyalgia patients. This study compared post-traumatic stress disorder symptoms in fibromyalgia patients and healthy controls and determined whether patient-control differences in post-traumatic stress disorder symptoms mediated differences in mental health. In all, 30 patients and 30 healthy controls completed questionnaires assessing symptoms of post-traumatic stress disorder and mental health. Fibromyalgia patients had greater symptoms of post-traumatic stress disorder and mental health than controls. Patient-control differences in mental health symptoms were fully or partially mediated by differences in post-traumatic stress disorder symptoms. Healthcare providers should understand the role of trauma as management of trauma symptoms may be one strategy for improving mental health.

Visual Place Learning in Drosophila melanogaster
Ofstad, Tyler A.; Zuker, Charles S.; Reiser, Michael B.
2011-01-01
The ability of insects to learn and navigate to specific locations in the environment has fascinated naturalists for decades. While the impressive navigation abilities of ants, bees, wasps, and other insects clearly demonstrate that insects are capable of visual place learning1–4, little is known about the underlying neural circuits that mediate these behaviors. Drosophila melanogaster is a powerful model organism for dissecting the neural circuitry underlying complex behaviors, from sensory perception to learning and memory. Flies can identify and remember visual features such as size, color, and contour orientation5, 6. However, the extent to which they use vision to recall specific locations remains unclear. Here we describe a visual place-learning platform and demonstrate that Drosophila are capable of forming and retaining visual place memories to guide selective navigation. By targeted genetic silencing of small subsets of cells in the Drosophila brain we show that neurons in the ellipsoid body, but not in the mushroom bodies, are necessary for visual place learning. Together, these studies reveal distinct neuroanatomical substrates for spatial versus non-spatial learning, and substantiate Drosophila as a powerful model for the study of spatial memories.

The purpose of the present study was to compare response inhibition and cognitive appraisal in clients with acute stress disorder, clients with posttraumatic stress disorder, and normal individuals. This was a comparative study. The sample consisted of 40 clients with acute stress disorder, 40 patients with posttraumatic stress disorder, and 40 normal individuals from Mazandaran province selected through convenience sampling method. Data were collected using Composite International Diagnostic Interview, Stroop Color-Word Test, Posttraumatic Cognitions Inventory, and the Impact of Event Scale. Results showed that individuals with acute stress disorder are less able to inhibit inappropriate responses and have more impaired cognitive appraisals compared to those with posttraumatic stress disorder. Moreover, results showed that response inhibition and cognitive appraisal explain 75% of the variance in posttraumatic stress disorder symptoms and 38% of the variance in posttraumatic stress disorder symptoms. The findings suggest that response inhibition and cognitive appraisal are two variables that influence the severity of posttraumatic stress disorder and acute stress disorder symptoms. Also, these results have important implications for pathology, prevention, and treatment of posttraumatic stress disorder and acute stress disorder.

A neural model proposes how entorhinal grid cells and hippocampal place cells may develop as spatial categories in a hierarchy of self-organizing maps (SOMs). The model responds to realistic rat navigational trajectories by learning both grid cells with hexagonal grid firing fields of multiple spatial scales, and place cells with one or more firing fields, that match neurophysiological data about their development in juvenile rats. Both grid and place cells can develop by detecting, learning and remembering the most frequent and energetic co-occurrences of their inputs. The model's parsimonious properties include: similar ring attractor mechanisms process linear and angular path integration inputs that drive map learning; the same SOM mechanisms can learn grid cell and place cell receptive fields; and the learning of the dorsoventral organization of multiple spatial scale modules through medial entorhinal cortex to hippocampus (HC) may use mechanisms homologous to those for temporal learning through lateral entorhinal cortex to HC ('neural relativity'). The model clarifies how top-down HC-to-entorhinal attentional mechanisms may stabilize map learning, simulates how hippocampal inactivation may disrupt grid cells, and explains data about theta, beta and gamma oscillations. The article also compares the three main types of grid cell models in the light of recent data.
Coping Self-Efficacy Mediates the Effects of Negative Cognitions on Posttraumatic Distress
Cieslak, Roman; Benight, Charles C.; Lehman, Victoria Caden
2008-01-01
Although cognitive distortions have predicted posttraumatic distress after various types of traumatic events, the mechanisms through which cognitive distortions influence posttraumatic distress remain unclear. We hypothesized that coping self-efficacy, the belief in one’s own ability to manage posttraumatic recovery demands, would operate as a mediator between negative cognitions (about self, about the world, and self-blame beliefs) and posttraumatic distress. In the cross-sectional Study 1, data collected among 66 adult female victims of child sexual abuse indicated that coping self-efficacy mediated the effects of negative cognitions about self and about the world on posttraumatic distress. The same pattern of results was found in a longitudinal Study 2, conducted among 70 survivors of motor vehicle accidents. Coping self-efficacy measured at 1 month after the trauma mediated the effects of 7-day negative cognitions about self and about the world on 3-month posttraumatic distress. In both studies self-blame was not related to posttraumatic distress and the effect of self-blame on posttraumatic distress was not mediated by coping self-efficacy. The results provide insight into a mechanism through which negative cognitions may affect posttraumatic distress and highlight the potential importance of interventions aimed at enhancing coping self-efficacy beliefs.

Vicarious exposure to trauma is ubiquitous in palliative medicine. Repeated exposure to trauma may contribute to compassion fatigue and posttraumatic stress disorder symptoms in medical and supportive care professionals such as physicians, nurses, and social workers. These symptoms may be intensified among medical and supportive care professionals who use avoidant or rigid coping strategies. This study aimed to provide an estimate of posttraumatic stress disorder symptoms in a sample of professionals who work in palliative care settings, and have already been enrolled in mindfulness-based communication training. Palliative care providers provided self-reported ratings of posttraumatic stress disorder symptoms, depression, and coping strategies using validated measures including the Acceptance and Action Questionnaire, Cognitive Fusion Questionnaire, and the Posttraumatic Stress Disorder Checklist-Civilian Version. A total of 21 professionals working with palliative care patients completed assessments prior to beginning mindfulness-based communication training. Posttraumatic stress disorder symptoms were prevalent in this sample of professionals; 42% indicated positive screens for significant posttraumatic stress disorder symptoms, and 33% indicated probable posttraumatic stress disorder diagnosis. Posttraumatic stress disorder symptoms may be common among professionals working in palliative medicine. Professionals prone to avoidant coping and those with more rigid negative thought processes may be at higher risk for posttraumatic stress disorder symptoms. © The Author(s) 2015.

Place and Response Learning in the Open-field Tower Maze.
Lipatova, Olga; Campolattaro, Matthew M; Toufexis, Donna J; Mabry, Erin A
2015-10-28
This protocol describes how the Open-field Tower Maze (OFTM) paradigm is used to study spatial learning in rodents. This maze is especially useful for examining how rats learn to use a place- or response-learning to successfully navigate in an open-field arena. Additionally, this protocol describes how the OFTM differs from other behavioral maze paradigms that are commonly used to study spatial learning in rodents. The OFTM described in this article was adapted from the one previously described by Cole, Clipperton, and Walt (2007). Specifically, the OFTM was created to test spatial learning in rodents without the experimenter having to consider how "stress" might play a role as a confounding variable. Experiments have shown that stress-alone can significantly affect cognitive function(1). The representative results section contains data from an experiment that used the OFTM to examine the effects of estradiol treatment on place- and response-learning in adult female Sprague Dawley rats(2). Future studies will be designed to examine the role of the hippocampus and striatum in place- and response-learning in the OFTM.
Learning about stress: neural, endocrine and behavioral adaptations.
McCarty, Richard
2016-09-01
In this review, nonassociative learning is advanced as an organizing principle to draw together findings from both sympathetic-adrenal medullary and hypothalamic-pituitary-adrenocortical (HPA) axis responses to chronic intermittent exposure to a variety of stressors. Studies of habituation, facilitation and sensitization of stress effector systems are reviewed and linked to an animal's prior experience with a given stressor, the intensity of the stressor and the appraisal by the animal of its ability to mobilize physiological systems to adapt to the stressor. Brain pathways that regulate physiological and behavioral responses to stress are discussed, especially in light of their regulation of nonassociative processes in chronic intermittent stress. These findings may have special relevance to various psychiatric diseases, including depression and post-traumatic stress disorder (PTSD).

Post-Traumatic Stress Disorder (PTSD) is a psychiatric chronic disease developing in individuals after the experience of an intense and life-threatening traumatic event. The post-traumatic symptomatology encompasses alterations in memory processes, mood, anxiety and arousal. There is now consensus in considering the disease as an aberrant adaptation to traumatic stress. Pharmacological research, aimed at the discovery of new potential effective treatments, has lately directed its attention towards the "so-called" cognitive enhancers. This class of substances, by modulating cognitive processes involved in the development and/or persistence of the post-traumatic symptomatology, could be of great help in improving the outcome of psychotherapies and patients' prognosis. In this perspective, drugs acting on the endocannabinoid system are receiving great attention due to their dual ability to modulate memory processes on one hand, and to reduce anxiety and depression on the other. The purpose of the present review is to offer a thorough overview of both animal and human studies investigating the effects of cannabinoids on memory processes. First, we will briefly describe the characteristics of the endocannabinoid system and the most commonly used animal models of learning and memory. Then, studies investigating cannabinoid modulatory influences on memory consolidation, retrieval and extinction will be separately presented, and the potential benefits associated with each approach will be discussed. In the final section, we will review literature data reporting beneficial effects of cannabinoid drugs in PTSD patients. Copyright © 2016 Elsevier Ltd. All rights reserved.

This study examined whether posttraumatic stress specifically resulting from intimate partner violence (IPV-related posttraumatic stress) mediated relationships between types of IPV and drug and alcohol problems among 212 women currently experiencing IPV. Six-month prevalence was high for drug use (48%) and alcohol use (59%). Structural equation modeling revealed that the frequency of physical, sexual, and psychological IPV were significantly and positively related to greater IPV-related posttraumatic stress, and IPV-related posttraumatic stress was significantly and positively related to drug problems. Further, IPV-related posttraumatic stress mediated the relationships between physical IPV and drug problems and psychological IPV and drug problems. Findings suggest that prevention and intervention efforts targeting posttraumatic stress among IPV-exposed women may reduce drug problems in this population.

Post-traumatic stress was assessed in early and late pregnancy, and 1, 4, 7, and 11 months postpartum by means of questionnaires among 1224 women. Thirty-seven women (3%) had post-traumatic stress (meeting criteria B, C, and D for PTSD) at least once within 1-11 months postpartum. In pregnancy, depression, severe fear of childbirth, 'pre'-traumatic stress, previous counseling related to pregnancy/childbirth, and self-reported previous psychological problems were associated with an increased risk of having post-traumatic stress within 1-11 months postpartum. Sum-scores of post-traumatic stress did not decrease over time among women who at least once had post-traumatic stress (criteria B, C, and D) within 1-11 months postpartum. Women with post-traumatic stress also showed a decrease in perceived social support over time postpartum.

Classical fear acquisition and extinction are important models for the etiology and treatment of anxiety disorders such as posttraumatic stress disorder (PTSD). Women are at a higher risk for PTSD than men. Levels of circulating 17-β estradiol (E2) in women have been linked to deficits in fear extinction and extinction recall. In PTSD, fear learning coincides with acute traumatic stress. However, little is known about the possible interaction between stress exposure and hormone status on fear acquisition and extinction learning. In a 2-day, 2×3 between-subjects design with healthy participants, we examined the effects of stress (psychosocial stressor vs. control, placed 45 min prior to conditioning) and natural E2-status on differential fear conditioning, covering fear acquisition, immediate extinction (Day 1), and 24h-delayed extinction recall (Day 2). To operationalize E2-status, we compared women in the early follicular phase (EF) of their menstrual cycle (low E2, low progesterone plasma levels), women in the midcycle phase (MC, high E2, low progesterone), and men. Conditioning was indicated by differential skin conductance responses. We found an interaction between stress exposure and natural E2-status in women only: In MC-women, extinction recall on Day 2 (24h after initial extinction training) was better when fear acquisition had been preceded by stress. In EF-women, the inverse was true. We show that extinction recall of conditioned fear acquired after stress depends on estrogen status in women. Therefore, extinction-based exposure therapy in free-cycling female anxiety patients should take cycle status into account. Copyright © 2014 Elsevier Ltd. All rights reserved.

More than half of all sexual assault victims report experiencing sexual victimization more than once. The aim of this paper was to determine the role post-traumatic cognition plays in the relationship between a history of sexual abuse and post-traumatic stress symptoms in sexual assault victims. The relationship between a history of sexual assault and the severity of post-traumatic stress symptoms was investigated retrospectively using data from a sexual assault crisis center in Korea. Data on psychological symptoms were collected in person at the initial assessment and by telephone 1 month later using the Post-traumatic Cognitions Inventory and the Post-traumatic Stress Disorder Symptoms Scale: Self-report Version. Of 105 women included in the analysis, 10 (9.5%) reported prior sexual abuse and were classified as sexually revictimized. Revictimized women had more post-traumatic negative cognition at initial assessment (t = −2.98; P = 0.004) and more post-traumatic symptoms at 1 month follow-up (t = −2.39; P = 0.019) than singly victimized women. At 1 month follow-up, the severity of post-traumatic stress symptoms had increased in revictimized women but had decreased slightly in singly victimized women. Negative post-traumatic cognition fully mediated the association between a history of sexual abuse and the severity of post-traumatic stress symptoms. Early detection of sexually revictimized women and tailored service and treatment intervention is needed to better serve this group of victims. Interventions targeted at preventing revictimization or post crime victimization may also help victims recover from the trauma and prevent future abuse. PMID:28875614

This study examines the relationship between adult attachment style and posttraumatic stress symptomatology in a volunteer sample of adults who reported the experience of childhood abuse. Sixty-six individuals completed measures of abuse history, attachment style, and posttraumatic stress symptomatology. Results indicated that 76% of participants endorsed one of the three insecure attachment styles (dismissing, fearful, or preoccupied). Analyses of variances revealed that those who displayed fearful and preoccupied attachment styles, which represent a negative view of the self, had the highest mean scores on posttraumatic symptoms. Correlational analyses revealed a significant positive relationship between negative view of self and posttraumatic stress symptomatology, but not between negative view of other and posttraumatic stress symptomatology. Regression analyses indicated that having a negative view of self was most highly associated with posttraumatic stress symptoms, followed by a history of physical abuse. The regression analysis further indicated that negative view of other was unrelated to posttraumatic stress symptoms.
The role of resilience and gratitude in posttraumatic stress and growth following a campus shooting.

This study investigated the role of resilience and gratitude in the relationship between trauma exposure, posttraumatic stress (PTS), and posttraumatic growth (PTG) following the campus shooting at Seattle Pacific University. The prevalence of community traumatic events such as school shootings has increased dramatically in the last decade. However, a significant number of individuals report positive changes such as enhanced appreciation for life, suggesting that some people are able to convert adverse experiences into personal growth. The purpose of this study was to understand characteristics about trauma and protective characteristics that contribute to PTG. Participants were 359 students, faculty, and staff (75% female; mean age = 27.26, SD = 12.61) enrolled or employed the day the shooting took place. Approximately four months following the event respondents completed self-report questionnaires about trauma exposure (i.e., physical and emotional proximity), PTS symptoms, PTG, resilience, and gratitude. Results supported our moderated-mediation hypothesis (B = 3.97, t = 4.11, 95th confidence interval [2.08, 5.88], p < .01), suggesting that both resilience and gratitude can be conceptualized as protective mechanisms, with resilience operating to prevent adverse outcomes while gratitude may promote positive outcomes following trauma. Given the prevalence of lifetime trauma, findings indicate that mental health professionals should consider a multifaceted approach to buffer the effects of trauma by preventatively cultivating resilience and enhancing gratitude in posttrauma interventions as a means to decrease PTS and increase PTG. Additional research is needed to understand how individuals develop positive traits as both protective and coping mechanisms. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

To evaluate posttraumatic stress disorder in children who have been admitted to the pediatric intensive care unit and their families. Studies were identified through PubMed, MEDLINE, and Ovid. All descriptive, observational, and controlled studies with a focus on posttraumatic stress disorder and the pediatric intensive care unit were included. Posttraumatic stress disorder rates in children following admission to the pediatric intensive care unit were between 5% and 28%, while rates of posttraumatic stress disorder symptoms were significantly higher, 35% to 62%. There have been inconsistencies noted across risk factors. Objective and subjective measurements of disease severity were intermittently positively associated with development of posttraumatic stress disorder. There was a positive relationship identified between the child's symptoms of posttraumatic stress disorder and their parents' symptoms.The biological mechanisms associated with the development of posttraumatic stress disorder in children admitted to the pediatric intensive care unit have yet to be explored. Studies in children following burn or other unintentional injury demonstrate potential relationships between adrenergic hormone levels and a diagnosis of posttraumatic stress disorder. Likewise genetic studies suggest the importance of the adrenergic system in this pathway.The rates of posttraumatic stress disorder in parents following their child's admission to the pediatric intensive care unit ranged between 10.5% and 21%, with symptom rates approaching 84%. It has been suggested that mothers are at increased risk for the development of posttraumatic stress disorder compared to fathers. Objective and subjective measures of disease severity yielded mixed findings with regard to the development of posttraumatic stress disorder. Protective parental factors may include education or the opportunity to discuss the parents' feelings during the admission. Following admission to the pediatric intensive care unit, both children and their parents have high rates of trauma exposure, both personally and secondary exposure via other children and their families, and subsequently are reporting significant rates of posttraumatic stress disorder. To effectively treat our patients, we must recognize the signs of posttraumatic stress disorder and strive to mitigate the negative effects.

Importance Combat places soldiers at risk for post-traumatic stress disorder (PTSD). The excessive rates of PTSD and other adjustment disorders in soldiers returning home make it imperative to identify risk and resilience factors that could be targeted by novel therapeutic treatments. Objective To investigate the interplay among attention to threat, combat exposure, and other risk factors for PTSD symptoms in soldiers deployed to combat. Design and Setting Longitudinal prospective study of Israeli Defense Force infantry soldiers carried out in 2008 through 2010. Repeated measurements during a 1-year period included baseline and predeployment data collected in training camps and deployment data collected in the combat theater. Participants Infantry soldiers (1085 men; mean age,18.8 years). Main Outcome Measures Postcombat PTSD symptoms. Results Soldiers developed threat vigilance during combat deployment, particularly when they were exposed to high-intensity combat, as indicated by faster response times to targets appearing at the location of threat relative to neutral stimuli (P < .001). Threat-related attention bias also interacted with combat exposure to predict risk for PTSD (P <.05). Bias toward threat at recruitment (P <.001) and bias away from threat just before deployment (P < .05) predicted postcombat PTSD symptoms. Moreover, these threat-related attention associations with PTSD were moderated by genetic and environmental factors, including serotonin transporter (5-HTTLPR) genotype. Conclusions and Relevance Combat exposure interacts with threat-related attention to place soldiers at risk for PTSD, and interactions with other risk factors account for considerable variance in PTSD vulnerability. Understanding these associations informs research on novel attention bias modification techniques and prevention of PTSD. PMID:23407816

Objective To assess the prevalence of post-traumatic stress disorder (PTSD) symptoms among governmental employees after the 2011 Oslo bombing attack targeted towards the Norwegian Ministries, and to explore the importance of proximity to the bomb explosion as a predictor of PTSD. Design A cross-sectional study. Setting Data were collected from a survey 10 months after the Oslo bombing on 22 July 2011. Participants A total of 3520 employees were invited to the study. Net samples comprised 1927 employees in 14 of the 17 Norwegian Ministries. Outcome measures The employees reported where they were at the time of the explosion. PTSD was assessed with the Norwegian version of the PTSD checklist (PCL). Results A total of 207 of the 1881 (11%) ministerial employees who completed the survey were present at work when the bomb exploded. Of these, a quarter (24%, 95% CI 18.4 to 30.0) had symptom levels equivalent to PTSD, while the prevalence was approximately 4% among those not present at work. In the latter group the prevalence was similar irrespective of whether their location was in Oslo, other places in Norway or abroad. Leadership responsibility was associated with lower risk for PTSD. Conclusions The risk of PTSD is mainly associated with being present at work at the time of a terror attack. For those not present at work, the risk of PTSD is low and independent of proximity to the terror scene. The findings may have implications for planning and priority of healthcare services after a work place terror attack. PMID:23872287

For those not present at work, the risk of PTSD is low and independent of proximity to the terror scene. The findings may have implications for planning and priority of healthcare services after a work place terror attack.

Relationship dissolution is a distressing experience which can result in the emergence of posttraumatic stress (i.e. post-dissolution PTSS) and other psychological symptoms among college students. Little is known, however, whether posttraumatic stress cognitions and interpersonal dependency may influence the severity of these distress outcomes. This study examined the interrelationship between posttraumatic stress symptoms (PTSS), posttraumatic stress cognitions, interpersonal dependency and psychological co-morbidities following relationship dissolution. One hundred and eighty college students (M = 69, F = 111) who had experienced relationship dissolution completed the Posttraumatic Stress Diagnostic Scale, Posttraumatic Stress Cognition Inventory, Interpersonal Dependency Inventory and General Health Questionnaire-28. Posttraumatic stress symptoms following relationship dissolution (post-dissolution PTSS) were associated with increased psychological co-morbidities. Negative view of oneself and self-blame mediated between PTSS and psychological co-morbidities. Assertion of autonomy moderated the mediational effects of negative cognitions on psychological co-morbidities. People can develop PTSSs and other psychological symptoms following the dissolution of a romantic relationship. Their concept of self and tendency to seek independence and control played a key role in determining the severity of distress symptoms.

We compared social support with other potential psychosocial predictors of posttraumatic stress after cancer. These included family identification, or a sense of belonging to and commonality with family members, and family constraints, or the extent to which family members are closed, judgmental, or unreceptive in conversations about cancer. We also tested the hypothesis that family constraints mediate the relationship between family identification and cancer-related posttraumatic stress. We used a cross-sectional design. Surveys were collected from 205 colorectal cancer survivors in Tayside, Scotland. Both family identification and family constraints were stronger independent predictors of posttraumatic stress than social support. In multivariate analyses, social support was not a significant independent predictor of posttraumatic stress. In addition, there was a significant indirect effect of family identification on posttraumatic stress through family constraints. Numerous studies demonstrate a link between social support and posttraumatic stress. However, experiences within the family may be more important in predicting posttraumatic stress after cancer. Furthermore, a sense of belonging to and commonality with the family may reduce the extent to which cancer survivors experience constraints on conversations about cancer; this may, in turn, reduce posttraumatic stress.

Self-efficacy may be an important factor in individuals' recovery from posttraumatic stress reactions after a natural disaster. However, few longitudinal studies have investigated whether self-efficacy predicts the course of posttraumatic recovery beyond lower initial levels of distress. The purpose of the present study was to investigate whether general self-efficacy is related to recovery from posttraumatic stress reactions from a longitudinal perspective. A total of 617 Norwegians exposed to the 2004 Southeast Asian tsunami completed self-report questionnaires measuring their level of disaster exposure and general self-efficacy at 6 months and posttraumatic stress reactions 6 months and 2 years post-disaster. Predictors of changes in posttraumatic stress reactions were analyzed with multivariate mixed effects models. Self-efficacy at 6 months post-disaster was unrelated to trauma exposure and inversely related to posttraumatic stress reactions at 6 months and 2 years post-disaster. However, self-efficacy was not related to recovery from posttraumatic stress reactions between 6 months and 2 years post-disaster. In conclusion, general self-efficacy is related to lower levels of posttraumatic stress reactions in the first months after a disaster but does not appear to be related to improved recovery rates over the longer term.

The aim of this prospective study was to establish the degree to which parents report post-traumatic growth after the intensive care treatment of their child. Prospective cross-sectional cohort study. Paediatric Intensive Care Unit (PICU). A total of 50 parents of children, admitted to PICU for >12 h. Parents provided stress ratings as their child was discharged from PICU and, 4 months later, completed postal questionnaires rating their anxiety, depression, post-traumatic stress and post-traumatic growth. As much as 44 parents (88%) indicated on the Posttraumatic Growth Inventory (PTGI) [1] that they had experienced a positive change to a great degree as a result of their experiences in PICU. Parents of children who were ventilated (P = 0.024) reported statistically higher post-traumatic growth as did parents of older children (P = 0.032). PTGI scores were positively correlated with post-traumatic stress scores at 4 months (P = 0.021), but on closer inspection this relationship was found to be curvilinear. Post-traumatic growth emerged as a salient concept for this population. It was more strongly associated with moderate levels of post-traumatic stress, than high or low levels.

Exposure to traumatic events often results in severe distress which may elicit self-medication behaviors. Yet, some individuals exposed to trauma do not develop post-traumatic stress symptoms and comorbid addictive impulses. In the wake of traumatic events, psychological processes like thought suppression and mindfulness may modulate post-traumatic stress and craving for substances. We examined the differential roles of mindfulness and suppression in comorbid post-traumatic stress and craving in a sample of 125 persons with extensive trauma histories and psychiatric symptoms in residential treatment for substance dependence. Results indicated that thought suppression, rather than extent of trauma history, significantly predicted post-traumatic stress symptom severity while dispositional mindfulness significantly predicted both post-traumatic stress symptoms and craving. In multiple regression models, mindfulness and thought suppression combined explained nearly half of the variance in post-traumatic stress symptoms and one-quarter of the variance in substance craving. Moreover, multivariate path analysis indicated that prior traumatic experience was associated with greater thought suppression, which in turn was correlated with increased post-traumatic stress symptoms and drug craving, whereas dispositional mindfulness was associated with decreased suppression, post-traumatic stress, and craving. The maladaptive strategy of thought suppression appears to be linked with adverse psychological consequences of traumatic life events. In contrast, dispositional mindfulness appears to be a protective factor that buffers individuals from experiencing more severe post-traumatic stress symptoms and craving. PMID:22385734

WHAT IS KNOWN ON THE SUBJECT?: Although it is well known that coping with mental disorder is a traumatic experience, studies of the relationships between posttraumatic growth and the variables that can affect it are rarely found in the literature. The studies that do exist usually focus on posttraumatic growth after posttraumatic stress disorder has developed as a result of traumatic life events such as earthquakes, wars, accidents or physical disease. In the literature, there exist few studies of patients diagnosed with psychosis. WHAT DOES THIS PAPER ADD TO EXISTING KNOWLEDGE?: This study shows that posttraumatic growth can be seen in patients after the diagnosis of mental disorders. Patients who use effective coping methods show more posttraumatic growth. In addition, patients who are satisfied with the nursing care received in the clinic show more posttraumatic growth. This indicates that care delivered by psychiatric nurses contributes to the posttraumatic growth of the patients. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Psychiatric nurses who recognize that suffering a mental disorder is a traumatic experience and that patients can grow from this experience can contribute to the posttraumatic growth of those in their care. When they see signs of posttraumatic growth, nurses can teach patients how to cope with that stress effectively and how to share their feelings, thoughts and experiences related to the situation. In addition, psychosocial interventions such as trauma-focused cognitive behavioural therapy and eye movement desensitization can be used to aid posttraumatic growth. Introduction Although it is recognized that suffering a mental illness is a traumatic experience, the fact that this can lead to posttraumatic growth and the variables that may affect the situation are rarely discussed in the literature. Aim This study was conducted to determine the effects of coping styles and nursing care perceptions on posttraumatic growth in mental disorders. Method The descriptive study was conducted at a psychiatric clinic with a personal information form and three-scale test. Results In the study, completed with 122 psychiatric inpatients, it was found that patients were using effective methods to cope with stress, were satisfied with nursing care and had high posttraumatic growth. Moreover, it was found that effective coping styles and satisfaction with nursing care positively affected the posttraumatic growth level of patients. Discussion The results support the proposition that using effective coping styles and seeking professional support after traumatic life events influence posttraumatic growth levels. Implications for practice Psychiatric nurses should be aware of the fact that developing a mental disorder is a traumatic life event after which posttraumatic growth can occur. They should encourage posttraumatic growth by teaching effective coping methods, providing psychiatric care and using psychosocial interventions such as trauma-focused cognitive behavioural therapy and eye movement desensitization. © 2018 John Wiley & Sons Ltd.
Epigenetic Mechanisms in Learned Fear: Implications for PTSD
Zovkic, Iva B; Sweatt, J David
2013-01-01
One of the most exciting discoveries in the learning and memory field in the past two decades is the observation that active regulation of gene expression is necessary for experience to trigger lasting functional and behavioral change, in a wide variety of species, including humans. Thus, as opposed to the traditional view of ‘nature' (genes) being separate from ‘nurture' (environment and experience), it is now clear that experience actively drives alterations in central nervous system (CNS) gene expression in an ongoing fashion, and that the resulting transcriptional changes are necessary for experience to trigger altered long-term behavior. In parallel over the past decade, epigenetic mechanisms, including regulation of chromatin structure and DNA methylation, have been shown to be potent regulators of gene transcription in the CNS. In this review, we describe data supporting the hypothesis that epigenetic molecular mechanisms, especially DNA methylation and demethylation, drive long-term behavioral change through active regulation of gene transcription in the CNS. Specifically, we propose that epigenetic molecular mechanisms underlie the formation and stabilization of context- and cue-triggered fear conditioning based in the hippocampus and amygdala, a conclusion reached in a wide variety of studies using laboratory animals. Given the relevance of cued and contextual fear conditioning to post-traumatic stress, by extension we propose that these mechanisms may contribute to post-traumatic stress disorder (PTSD) in humans. Moreover, we speculate that epigenetically based pharmacotherapy may provide a new avenue of drug treatment for PTSD-related cognitive and behavioral function. PMID:22692566
Second language acquisition after traumatic brain injury: a case study.
Połczyńska-Fiszer, M; Mazaux, J M
2008-01-01
Post-traumatic language and memory impairment, as well as a subsequent recovery in monolinguals have been widely documented in the literature, yet little is known about learning the second language after a severe head trauma followed by coma, as well as the relationship of this process with cognitive recovery, psychological status and quality of life. The present study investigates the relationship of learning the second language (English) in the process of rehabilitation, with quality of life in a Polish female university student who, as a result of a car accident, suffered a major closed-head injury and was comatose for a month. The subject was enrolled in an English learning program nine months after the trauma. The experiment lasted six months and comprised monthly meetings. The patient improved the major components of the second language, including vocabulary. Within the 6 months, the subject was gradually capable of learning additional and more complex lexical items. Learning the second language after traumatic brain injury may positively influence emotional well-being, self-esteem, and, perhaps, recovery of quality of life. A long-term beneficial effect of learning L2 was a consequential improvement of the patient's memory.
Goal-oriented robot navigation learning using a multi-scale space representation.

There has been extensive research in recent years on the multi-scale nature of hippocampal place cells and entorhinal grid cells encoding which led to many speculations on their role in spatial cognition. In this paper we focus on the multi-scale nature of place cells and how they contribute to faster learning during goal-oriented navigation when compared to a spatial cognition system composed of single scale place cells. The task consists of a circular arena with a fixed goal location, in which a robot is trained to find the shortest path to the goal after a number of learning trials. Synaptic connections are modified using a reinforcement learning paradigm adapted to the place cells multi-scale architecture. The model is evaluated in both simulation and physical robots. We find that larger scale and combined multi-scale representations favor goal-oriented navigation task learning. Copyright © 2015 Elsevier Ltd. All rights reserved.

Executive function in cancer patients with posttraumatic stress disorder.
Yang, Juan; Guo, Juncheng; Jiang, Xiangling
2017-03-01
Background Cancer patients with posttraumatic stress disorder can lead to their noncompliant behaviors. However, less is known about the neurocognitive functioning of posttraumatic stress disorder in general cancer types or patient populations. The current study attempted to examine the prevalence of posttraumatic stress disorder and their relationships with executive function in individuals with cancer. Methods A total of 285 cancer patients with posttraumatic stress disorder and 150 healthy individuals were recruited for the present study. The Clinician Administered PTSD Scale, Tower of Hanoi, Wisconsin Card Sorting Test, and Wechsler Adult Intelligence Scale-Revised Chinese revision were administered to all participants. Results Significant differences in the score of Tower of Hanoi, Wisconsin Card Sorting Test, and Wechsler Adult Intelligence Scale-Revised Chinese revision were observed between the posttraumatic stress disorder group and the healthy control group ( p < 0.001). Significant correlations were found between all posttraumatic stress disorder symptoms and executive function. Conclusions These findings suggest that individuals with cancer-related posttraumatic stress disorder exhibit more severe impairment in executive function than healthy controls do.

Post-traumatic stress disorder is a common psychological maladaptation among adolescents after undergoing an earthquake. Knowledge about the prevalence and maintenance of post-traumatic stress disorder symptoms and the changes of its predictors over time can help medical providers assist adolescent survivors with mitigating long-term impacts. This study examined the changes in posttraumatic stress disorder symptoms and its relationship with coping skill and locus of control among adolescent earthquake survivors in China. The study used an observational longitudinal design. A total of 1420 adolescents were evaluated twice after the earthquake by using the Post-traumatic stress disorder Checklist-Civilian Version, The Internality, Powerful others and Chance scale and the Coping Styles Scale. The results indicated that the mean scores of posttraumatic stress disorder symptoms were decreased significantly and the positive rates of posttraumatic stress disorder symptoms also declined remarkably at 17 months compared to the 3 months post-earthquake. Internality locus of control and problem solving coping skill were effective resilient factors for the development and maintenance of posttraumatic stress disorder symptoms, while chance locus of control was a powerful risk factor of posttraumatic stress disorder symptoms as well as being female, being injured and property loss. Continuous screening is recommended to identify adolescent earthquake survivors with posttraumatic stress disorder symptoms. More attention should be paid to adolescent survivors who are prone to adopt passive coping strategies responding to trauma events and who own external causal attribution.

Posttraumatic growth at end of life, a positive psychological consequence of dealing with a life crisis, may be catalyzed by the trauma of facing mortality. Studies on cancer patients' posttraumatic growth have overwhelmingly examined early-stage survivors. Of the few studies on advanced cancer patients, none anchored posttraumatic growth with the patient's death. Therefore, the purposes of this study were to describe longitudinal changes in and to identify determinants of posttraumatic growth over the dying process. A convenience sample of 313 cancer patients was recruited and followed until death. Posttraumatic growth was measured by the Posttraumatic Growth Inventory. Determinants were evaluated from sociodemographics, cancer characteristics, social context variables, and coping strategies using a multiple linear regression model. The dying process may be too threatening and stressful for cancer patients to experience profound posttraumatic growth as manifested by low Posttraumatic Growth Inventory scores (26.13 ± 21.59 to 40.33 ± 27.71 on a 0-105 scale) without significant changes as death approached. However, terminally ill cancer patients who were not defeated by the initial threat of death experienced posttraumatic growth. Patients were at risk for low-level posttraumatic growth if they were male, were non-middle aged, had low educational attainment, had a non-metastatic disease, recently recognized terminally ill status, had severe symptom distress, had high functional dependence and weak social support, and were unaware or had low acceptance of their prognosis. Interventions are needed to appropriately relieve symptom distress, facilitate functional independence, enhance social support, and improve prognostic awareness and acceptance to inspire positive changes for cancer patients at end of life.

Correlates of posttraumatic stress disorder in adults with congenital heart disease.
Eslami, Bahareh
2017-05-01
The aims of this study were to compare the level of posttraumatic stress disorder between adults with and without congenital heart disease, and to examine the correlates of posttraumatic stress disorder (e.g., sociodemographics). Cross-sectional. Two university-affiliated heart hospitals in Tehran, Iran. A sample of 347 adults with congenital heart disease aged 18-64 years (52% women), and 353 adults without congenital heart disease matched by sex and age (±2 years) was recruited. The PTSD Scale: Self-report version was used to assess the diagnosis and severity of posttraumatic stress disorder. Hierarchical multivariate logistic regression analyses were performed to explore correlates of likely posttraumatic stress disorder diagnosis among each group of participants. The posttraumatic stress disorder in the patients was comparable to those of the control group, except for increased arousal (P = .027) which was scored higher among the patients. Over 52% of adults with congenital heart disease met the criteria for a likely posttraumatic stress disorder diagnosis compared with 48% of adults without congenital heart disease. The regression analyses among patients revealed that elevated depressive symptoms (OR = 1.27) and a positive history of cardiac surgery (OR = 2.02) were significantly associated with posttraumatic stress disorder. The model could explain 29% of the variance in posttraumatic stress disorder. The high and comparable prevalence of posttraumatic stress disorder among patients and nonpatients highlight the significance of the context in which adults with congenital heart disease may face other/additional stressors than disease-related ones, an issue that clinicians need also take into account. Furthermore, the association of posttraumatic stress disorder with elevated depressive symptoms warrant a comprehensive psychological assessment and management of adults with congenital heart disease, in particular among those with a history of invasive procedures. © 2017 Wiley Periodicals, Inc.
Post-traumatic psychiatric disorders: PTSD is not the only diagnosis.
Auxéméry, Yann
2018-05-01
Traumatic events and their consequences are often hidden or minimised by patients for reasons linked to the post-traumatic stress disorder itself (inexpressibility, shame, depressive thoughts, fear of stigmatisation, etc.). Although post-traumatic stress disorder (PTSD) remains the most widely known disorder, chronic post-traumatic psychiatric disorders are many and varied. After a trauma, the practitioner has to check for the different clinical forms of post-traumatic psychological consequences: PTSD is not the only diagnosis. Based on our own clinical experience compared to the international literature, we think necessary to build a didactic classification describing chronic post-traumatic symptoms and syndromes. Post traumatic depressions and bereavement lead to high risk of suicidal crisis and self-harm behaviours. Re-experiencing are felt with anxiety, hyper arousal increases anxious reactivity, and avoidance strategies increase anticipatory anxiety, indicating post-traumatic anxiety disorders (agoraphobia, specific phobia, obsessive compulsive disorder, separation anxiety, social phobia). Characterising an often-severe clinical picture, the co-occurrence of post-traumatic and chronic psychotic symptoms is not unusual (post-traumatic schizophrenia, post-traumatic depression with mood-congruent psychotic features, non-schizophrenic post-traumatic psychotic disorder, and bipolar reaction to trauma). A physical injury occurring at the same time as a traumatic exposure increases the risk of developing post-traumatic stress disorder later which, in turn, afflicts the subjective perception of the physical health (development of somatoform and psychosomatic disorders, comorbidity with a post-concussion syndrome). The trauma may cause a rupture in the biography of a person, also in his/her internal physiological functioning as in his/her social activities (impacts of instinctive functions and behaviours, personality changes, and adjustment difficulties on professional and personal life). Although a nomenclature is necessary for semiological descriptions, a thorough analysis of the patient's general psychological functioning must also be conducted.

Background Traumatic experiences, such as natural disasters, produce multiple and serious impacts on people. Despite the traditional focus on negative consequences, in many cases there are also positive consequences, such as posttraumatic growth. Tedeschi and Calhoun proposed a model of posttraumatic growth that emphasizes the role of rumination after the basic beliefs breakdown due to the occurrence of a traumatic experience. Method A total of 238 volunteers affected by two major earthquakes and tsunami alerts in northern Chile on April 1 and 2, 2014, responded to an online survey measuring subjective severity, basic beliefs change, social share of emotion, rumination, posttraumatic stress, and posttraumatic growth. Results Path analyses reveal that posttraumatic stress goes through a negative change in basic beliefs, intrusive rumination, and deliberated rumination, meanwhile posttraumatic growth is only achieved directly from a positive change in basic beliefs and deliberated rumination. Discussion The model is consistent with the empirical model obtained in Chilean people affected by the earthquake and tsunami that occurred on 27 February, 2010, but it is slightly different and in a form that is more consistent with Tedeschi and Calhoun’s theoretical model. Both models remark on the role of deliberated rumination in posttraumatic growth and failure to progress from intrusive to deliberated rumination in posttraumatic stress, but the proposed one is more parsimonious and assumes subjective severity as an antecedent to basic belief changes. These conclusions must be considered in light of limitations that a cross-sectional design and the correlational nature of the statistical analysis carried out impose. Highlights of the article Role of subjective severity, change of basic beliefs, social sharing of emotion, and rumination on posttraumatic stress and growth were modeled from responses of people affected by the April 1–2, 2014, northern Chilean earthquakes.Posttraumatic stress goes through negative changes in basic beliefs, intrusive rumination, and deliberated rumination.Posttraumatic growth is achieved from positive changes in basic beliefs and deliberated rumination.Deliberated rumination and moving from intrusive to deliberated rumination appear as cornerstones in posttraumatic processing.

To conduct a systematic review and metaanalysis of the prevalence, risk factors, and prevention/treatment strategies for posttraumatic stress disorder symptoms in critical illness survivors. PubMed, Embase, CINAHL, PsycINFO, and Cochrane Library from inception through March 5, 2014. Eligible studies met the following criteria: 1) adult general/nonspecialty ICU, 2) validated posttraumatic stress disorder instrument greater than or equal to 1 month post-ICU, and 3) sample size greater than or equal to 10 patients. Duplicate independent review and data abstraction from all eligible titles/abstracts/full-text articles. The search identified 2,817 titles/abstracts, with 40 eligible articles on 36 unique cohorts (n = 4,260 patients). The Impact of Event Scale was the most common posttraumatic stress disorder instrument. Between 1 and 6 months post-ICU (six studies; n = 456), the pooled mean (95% CI) Impact of Event Scale score was 20 (17-24), and the pooled prevalences of clinically important posttraumatic stress disorder symptoms (95% CI) were 25% (18-34%) and 44% (36-52%) using Impact of Event Scale thresholds greater than or equal to 35 and greater than or equal to 20, respectively. Between 7 and 12 months post-ICU (five studies; n = 698), the pooled mean Impact of Event Scale score was 17 (9-24), and pooled prevalences of posttraumatic stress disorder symptoms were 17% (10-26%) and 34% (22-50%), respectively. ICU risk factors for posttraumatic stress disorder symptoms included benzodiazepine administration and post-ICU memories of frightening ICU experiences. Posttraumatic stress disorder symptoms were associated with worse quality of life. In European-based studies: 1) an ICU diary was associated with a significant reduction in posttraumatic stress disorder symptoms, 2) a self-help rehabilitation manual was associated with significant posttraumatic stress disorder symptom reduction at 2 months, but not 6 months; and 3) a nurse-led ICU follow-up clinic did not reduce posttraumatic stress disorder symptoms. Clinically important posttraumatic stress disorder symptoms occurred in one fifth of critical illness survivors at 1-year follow-up, with higher prevalence in those who had comorbid psychopathology, received benzodiazepines, and had early memories of frightening ICU experiences. In European studies, ICU diaries reduced posttraumatic stress disorder symptoms.

In South Africa, alcohol use poses a public health burden. Hazardous alcohol use often co-occurs with psychological distress (e.g., depression and post-traumatic stress). However, the majority of the research establishing the relationship between alcohol use and psychological distress has been cross-sectional, so the nature of co-occurring changes in psychological distress and alcohol use over time is not well characterized. The objective of this study is to examine the longitudinal relationship between psychological distress and alcohol use among South African women who attend alcohol serving venues. Four waves of data were collected over the course of a year from 560 women in a Cape Town township who attended drinking venues. At each assessment wave, participants reported depressive symptoms, post-traumatic stress symptoms, and alcohol use. Multilevel growth models were used to: 1) assess the patterns of alcohol use; 2) examine how depressive symptoms uniquely, post-traumatic stress symptoms uniquely, and depressive and post-traumatic stress symptoms together were associated with alcohol use; and 3) characterize the within person and between person associations of depressive symptoms and post-traumatic stress symptoms with alcohol use. Women reported high levels of alcohol use throughout the study period, which declined slightly over time. Post-traumatic stress symptoms were highly correlated with depressive symptoms. Modeled separately, both within person and between person depressive and post-traumatic stress symptoms were uniquely associated with alcohol use. When modeled together, significant between person effects indicated that women who typically have more post-traumatic stress symptoms, when controlling for depressive symptoms, are at risk for increased alcohol use; however, women with more depressive symptoms, controlling for post-traumatic stress symptoms, do not have differential risk for alcohol use. Significant within person effects indicated an interaction between depressive and post-traumatic stress symptoms; women reported more alcohol use than usual at times when they had higher post-traumatic stress symptoms, and this increase in alcohol use was further exacerbated for women who also had higher depressive symptoms than usual. These findings suggest that interventions targeting post-traumatic stress, especially when post-traumatic stress is comorbid with depression, may reduce alcohol use among South African women who drink.

A growing literature shows prominent sex effects for risk for post-traumatic stress disorder and associated medical comorbid burden. Previous research indicates that post-traumatic stress disorder is associated with reduced slow wave sleep, which may have implications for overall health, and abnormalities in rapid eye movement sleep, which have been implicated in specific post-traumatic stress disorder symptoms, but most research has been conducted in male subjects. We therefore sought to compare objective measures of sleep in male and female post-traumatic stress disorder subjects with age- and sex-matched control subjects. We used a cross-sectional, 2 × 2 design (post-traumatic stress disorder/control × female/male) involving83 medically healthy, non-medicated adults aged 19-39 years in the inpatient sleep laboratory. Visual electroencephalographic analysis demonstrated that post-traumatic stress disorder was associated with lower slow wave sleep duration (F(3,82) = 7.63, P = 0.007) and slow wave sleep percentage (F(3,82) = 6.11, P = 0.016). There was also a group × sex interaction effect for rapid eye movement sleep duration (F(3,82) = 4.08, P = 0.047) and rapid eye movement sleep percentage (F(3,82) = 4.30, P = 0.041), explained by greater rapid eye movement sleep in post-traumatic stress disorder females compared to control females, a difference not seen in male subjects. Quantitative electroencephalography analysis demonstrated that post-traumatic stress disorder was associated with lower energy in the delta spectrum (F(3,82) = 6.79, P = 0.011) in non-rapid eye movement sleep. Slow wave sleep and delta findings were more pronounced in males. Removal of post-traumatic stress disorder subjects with comorbid major depressive disorder, who had greater post-traumatic stress disorder severity, strengthened delta effects but reduced rapid eye movement effects to non-significance. These findings support previous evidence that post-traumatic stress disorder is associated with impairment in the homeostatic function of sleep, especially in men with the disorder. These findings suggest that group × sex interaction effects on rapid eye movement may occur with more severe post-traumatic stress disorder or with post-traumatic stress disorder comorbid with major depressive disorder. © 2013 European Sleep Research Society.

Translating findings from basic science, several compounds have been identified that may enhance therapeutic outcomes and/or expedite treatment gains when administered alongside exposure-based treatments. Four of these compounds (referred to as cognitive enhancers) have been evaluated in the context of randomized controlled trials for anxiety disorders (e.g., specific phobias, panic disorder, social anxiety disorder), obsessive compulsive disorder (OCD), and posttraumatic stress disorder (PTSD). These cognitive enhancers include D-cycloserine, yohimbine hydrochloride, glucocorticoids and cortisol, and brain derived neurotrophic factor. There is consistent evidence that cognitive enhancers can enhance therapeutic outcomes and/or expedite treatment gains across anxiety disorders, OCD, and PTSD. Emerging evidence has highlighted the importance of within-session fear habituation and between-session fear learning, which can either enhance fear extinction or reconsolidate of fear responses. Although findings from these trials are promising, there are several considerations that warrant further evaluation prior to wide-spread use of cognitive enhancers in exposure-based treatments. Consistent trial design and large sample sizes are important in future studies of cognitive enhancers. PMID:24972729

Zinc is a trace element important for synaptic plasticity, learning and memory. Zinc deficiency, both during pregnancy and after birth, impairs cognitive performance and, in addition to memory deficits, also results in alterations of attention, activity, neuropsychological behavior and motor development. The effects of zinc supplementation on cognition, particularly in the adult, are less clear. We demonstrate here in adult rats, that 4 week-long zinc supplementation given by drinking water, and approximately doubling normal daily intake, strongly impairs consolidation of hippocampal-dependent memory, tested through contextual fear conditioning and inhibitory avoidance. Furthermore, the same treatment started after memory consolidation of training for the same behavioral tests, substantially dampens the recall of the stressful event occurred 4 weeks before. A molecular correlate of the amnesic effect of zinc supplementation is represented by a dysregulated function of GSK-3ß in the hippocampus, a kinase that participates in memory processes. The possible relevance of these data for humans, in particular regarding post-traumatic stress disorders, is discussed in view of future investigation. Copyright © 2016 Elsevier B.V. and ECNP.

The prevailing neurocircuitry models of anxiety disorders have been amygdalocentric in form. The bases for such models have progressed from theoretical considerations, extrapolated from research in animals, to in vivo human imaging data. For example, one current model of posttraumatic stress disorder (PTSD) has been highly influenced by knowledge from rodent fear conditioning research. Given the phenomenological parallels between fear conditioning and the pathogenesis of PTSD, we have proposed that PTSD is characterized by exaggerated amygdala responses (subserving exaggerated acquisition of fear associations and expression of fear responses) and deficient frontal cortical function (mediating deficits in extinction and the capacity to suppress attention/response to trauma-related stimuli), as well as deficient hippocampal function (mediating deficits in appreciation of safe contexts and explicit learning/memory). Neuroimaging studies have yielded convergent findings in support of this model. However, to date, neuroimaging investigations of PTSD have not principally employed conditioning and extinction paradigms per se. The recent development of such imaging probes now sets the stage for directly testing hypotheses regarding the neural substrates of fear conditioning and extinction abnormalities in PTSD.
Concept Analysis of Posttraumatic Stress Disorder.
Sekhon, Bikram
2017-05-23
Mental health nursing is not the same as psychiatry, so it is important for nurses to have an understanding of the defining attributes, antecedents, consequences, model cases, and empirical referents of post-traumatic stress disorder (PTSD). Walker and Avant's (2005) method is used to guide this concept analysis of PTSD. Four attributes arise from this concept analysis, which are addressed through both the DSM-IV and DSM-5 (American Psychiatric Association, /): triggering event or events, re-experiencing, fear, and helplessness. Though a majority of the defining attributes are addressed through both versions of the DSM, a key fifth attribute arises through this concept analysis: a disruption of meaning. A better understanding of PTSD from a nursing perspective will help inform appropriate nursing interventions and prevention strategies, while expanding the knowledge synthesis and contribution of the nursing profession. A model case, borderline case, and contrary case of PTSD are provided. Discussion of the importance of a lack or loss of meaning in PTSD is included, along with exploration of transformative learning theory to inform clinical practice for nurses addressing a disruption of meaning. © 2017 NANDA International, Inc.

Feedback mechanisms in operant learning are critical for animals to increase reward or reduce punishment. However, not all conditions have a behavior that can readily resolve an event. Animals must then try out different behaviors to better their situation through outcome learning. This form of learning allows for novel solutions and with positive experience can lead to unexpected behavioral routines. Learned helplessness, as a type of outcome learning, manifests in part as increases in escape latency in the face of repeated unpredicted shocks. Little is known about the mechanisms of outcome learning. When fruit fly Drosophila melanogaster are exposed to unpredicted high temperatures in a place learning paradigm, flies both increase escape latencies and have a higher memory when given control of a place/temperature contingency. Here we describe discrete serotonin neuronal circuits that mediate aversive reinforcement, escape latencies, and memory levels after place learning in the presence and absence of unexpected aversive events. The results show that two features of learned helplessness depend on the same modulatory system as aversive reinforcement. Moreover, changes in aversive reinforcement and escape latency depend on local neural circuit modulation, while memory enhancement requires larger modulation of multiple behavioral control circuits.

We present a paradigm for assessing visuospatial working memory and skill learning in a rodent model, based on the place avoidance test. In our allothetic place avoidance alternation task (APAAT) the paradigm is comprised of minimal training sessions, tests various aspects of learning and memory and provides a rich set of parameters. A single working memory session consists of four conditions: habituation (no shock), two place avoidance training intervals (shock activated) and a retrieval test (shock inactivated). The location of the shock sector is alternated for each training day which initially requires extinction of previous representations and further working memory to achieve effective place avoidance across sessions. Visuospatial skill memory was evaluated by the shock/entrance ratio by tracking locomotor activity which is essential to execute a place avoidance strategy. For each day rats learned to avoid a new place with shock, as shown by a decreased number of entrances, and an increased time to the first entrance and maximum avoidance time. Skill learning improved according to the decreased number of shocks per entrance across conditions. These results indicate that complex cognitive functions are captured by this behavioral method. This APAAT paradigm expands and complements existing tools for studying hippocampal-prefrontal dependent functions to support development of treatment interventions. Copyright (c) 2010 Elsevier B.V.

[The psychopathology of immigrants and refugees].
Ekşi, Aysel
2002-01-01
The twentieth century witnessed major waves of emigration, exile and taking refuge abroad. In this paper, a review of the psychiatric literature published between 1990 and 2000 in English and Turkish is presented. Although refugees are considered to differ from economic migrants in a number of respects, they both experience culture and language change and may experience family disruption, social isolation, and hostility from the population of the host country. Accordingly, all refugees and immigrants go through stages of resettlement and need to integrate their past cultural experiences into their new life and culture. The process of integration depends on the subjects' age, mental integrity, and on the conditions he/she lives in. Research indicates that children acculturate more quickly and learn language faster than elders; but they may suffer from role reversal when they are expected to be linguistic and cultural translators for their parents. Young adults at the stage of identity formation can be cut off and feel alienated. Elderly persons have a higher risk of culture shock as they leave behind more memories and connections. These trigger different types of anxieties. The literature shows high levels of acculturative distress, and psychiatric disorders such as post-traumatic stress disorder, anxiety and depression, and refugees are considered to be at risk for suicidal behavior. The complex social and psychological needs of refugee and immigrant families place demands on special services for children, adolescents and adults.

To prevent deployment-related disorders, Chaos Driven Situations Management Retrieval System (CHARLY), a computer-aided training platform with a biofeedback interface has been developed. It simulates critical situations photorealistic for certain target and occupational groups. CHARLY was evaluated as a 1.5 days predeployment training method comparing it with the routine training. The evaluation was carried out for a matched random sample of N = 67 soldiers deployed in Afghanistan (International Security Assistance Force). Data collection took place before and after the prevention program and 4 to 6 weeks after deployment, which included mental state, post-traumatic stress disorder (PTSD) symptoms, knowledge of and attitude toward PTSD, and deployment-specific stressors. CHARLY has been significantly superior to the control group in terms of psychoeducation and attitude change. As to the mental state, both groups showed a significant increase in stress after deployment with significant lower increase in CHARLY. For PTSD-specific symptoms, CHARLY achieved a significant superiority. The fact that PTSD-specific scales showed significant differences at the end of deployment substantiates the validity of a specifically preventive effect of CHARLY. The study results tentatively indicate that highly standardized, computer-based primary prevention of mental disorders in soldiers on deployment might be superior to other more personal and less standardized forms of prevention.

Hippocampal place cells represent the cellular substrate of episodic memory. Place cell ensembles reorganize to support learning but must also maintain stable representations to facilitate memory recall. Despite extensive research, the learning-related role of place cell dynamics in health and disease remains elusive. Using chronic two-photon Ca2+ imaging in hippocampal area CA1 of wild-type and Df(16)A+/− mice, an animal model of 22q11.2 deletion syndrome, one of the most common genetic risk factors for cognitive dysfunction and schizophrenia, we found that goal-oriented learning in wild-type mice was supported by stable spatial maps and robust remapping of place fields toward the goal location. Df(16)A+/− mice showed a significant learning deficit accompanied by reduced spatial map stability and the absence of goal-directed place cell reorganization. These results expand our understanding of the hippocampal ensemble dynamics supporting cognitive flexibility and demonstrate their importance in a model of 22q11.2-associated cognitive dysfunction.

ABSTRACT Background: Posttraumatic stress symptoms are interconnected. Knowledge about which symptoms of posttraumatic stress are more strongly interconnected or central than others may have implications for the targeting of clinical interventions. Exploring whether symptoms of posttraumatic stress may be differentially related to covariates can contribute to our knowledge on how posttraumatic stress symptoms arise and are maintained. Objective: This study aimed to identify the most central symptoms of posttraumatic stress and their interconnections, and to explore how covariates such as exposure, sex, neuroticism, and social support are related to the network of symptoms of posttraumatic stress. Method: This study used survey data from ministerial employees collected approximately 10 months after the 2011 Oslo bombing that targeted the governmental quarters (n = 190). We conducted network analyses using Gaussian graphical models and the lasso regularization. Results: The network analysis revealed reliably strong connections between intrusive thoughts and nightmares, feeling easily startled and overly alert, and between feeling detached and emotionally numb. The most central symptom in the symptom network was feeling emotionally numb. The covariates were generally not found to have high centrality in the symptom network. An exception was that being female was connected to a high physiological reactivity to reminders of the trauma. Conclusions: Ten months after a workplace terror attack emotional numbness appears to be of high centrality in the symptom network of posttraumatic stress. Fear circuitry and dysphoric symptoms may constitute two functional entities in chronic posttraumatic stress. Clinical interventions targeting numbness may be beneficial in the treatment of posttraumatic stress, at least after workplace terrorism. PMID:29038689

This study examined the potential moderating effects of religiosity on the associations between exposure to acts of political violence and posttraumatic stress symptoms (PTS) among Jewish adolescents in Israel. In addition, it examined whether self-reported physical and interpersonal exposure to acts of political violence predicts PTS symptoms beyond the objective exposure effects (i.e., the proximity of participants' place of residence to high-, moderate-, or low-intensity political violence). A representative sample of 2,992 Jewish high school students (Grades 10 and 11) was taken. We used self-reporting to measure the level of religiosity and the Impact of Events Scale-Revised (IES-R) to measure PTS symptoms. Results show that self-reported exposure to acts of political violence adds a significant additional amount of variance to the prediction of PTS symptoms after objective exposure is already included in the regression equation. Religiosity was found as a risk factor for PTS symptoms such that the greater the religiosity of the adolescents, the higher their PTS symptoms. Therefore, prevention interventions should target the vulnerable group of religious Jewish adolescents.

Post-traumatic stress disorder (PTSD) occurs in 5-10% of the population and is twice as common in women as in men. Although trauma exposure is the precipitating event for PTSD to develop, biological and psychosocial risk factors are increasingly viewed as predictors of symptom onset, severity and chronicity. PTSD affects multiple biological systems, such as brain circuitry and neurochemistry, and cellular, immune, endocrine and metabolic function. Treatment approaches involve a combination of medications and psychotherapy, with psychotherapy overall showing greatest efficacy. Studies of PTSD pathophysiology initially focused on the psychophysiology and neurobiology of stress responses, and the acquisition and the extinction of fear memories. However, increasing emphasis is being placed on identifying factors that explain individual differences in responses to trauma and promotion of resilience, such as genetic and social factors, brain developmental processes, cumulative biological and psychological effects of early childhood and other stressful lifetime events. The field of PTSD is currently challenged by fluctuations in diagnostic criteria, which have implications for epidemiological, biological, genetic and treatment studies. However, the advent of new biological methodologies offers the possibility of large-scale approaches to heterogeneous and genetically complex brain disorders, and provides optimism that individualized approaches to diagnosis and treatment will be discovered.

Does stress damage the brain? Studies of adults with posttraumatic stress disorder have demonstrated smaller hippocampal volumes when compared with the volumes of adults with no posttraumatic stress disorder. Studies of children with posttraumatic stress disorder have not replicated the smaller hippocampal findings in adults, which suggests that smaller hippocampal volume may be caused by neurodevelopmental experiences with stress. Animal research has demonstrated that the glucocorticoids secreted during stress can be neurotoxic to the hippocampus, but this has not been empirically demonstrated in human samples. We hypothesized that cortisol volumes would predict hippocampal volume reduction in patients with posttraumatic symptoms. We report data from a pilot longitudinal study of children (n = 15) with history of maltreatment who underwent clinical evaluation for posttraumatic stress disorder, cortisol, and neuroimaging. Posttraumatic stress disorder symptoms and cortisol at baseline predicted hippocampal reduction over an ensuing 12- to 18-month interval. Results from this pilot study suggest that stress is associated with hippocampal reduction in children with posttraumatic stress disorder symptoms and provide preliminary human evidence that stress may indeed damage the hippocampus. Additional studies seem to be warranted.

In a randomised controlled study, a type of cognitive behavior therapy known as Rational Rehabilitation proved effective in the treatment of patients with chronic mental symptoms. Post-traumatic stress disorder is a serious illness that occurs frequently and can last for many years. Rational Rehabilitation may also be an effective treatment for post-traumatic stress disorder. To investigate, via a pilot study, on the effect of Rational Rehabilitation in patients with post-traumatic stress disorder, whether a randomised controlled study is called for. Nineteen patients with post-traumatic stress disorder, who were awaiting regular treatment, opted to join the study. The effect of Rational Rehabilitation was studied in relation to: symptoms of post-traumatic stress disorder, degree of happiness experienced, autonomy, social support and need for further treatment. results Rational Rehabilitation seems to have a positive effect on all outcome measures, except flashbacks. A controlled study of the effect of Rational Rehabilitation in patients with post-traumatic stress disorder seems justified.

Several theories suggest that posttraumatic intrusive symptoms are central to the relationship between childhood trauma (CT) and hallucinations and delusions in psychosis. Biased selective attention has been implicated as a cognitive process underlying posttraumatic intrusions. The current study sought to test theories of the relationship between childhood sexual abuse (CSA), hallucinations and delusions, posttraumatic intrusions, and selective attention in first-episode psychosis (FEP). Twenty-eight people with FEP and 21 nonclinical controls were assessed for CT and psychotic and posttraumatic stress symptoms and completed an emotional Stroop test using CSA-related and other words. Those with FEP and CSA had more severe hallucinations and delusions than those with FEP and without CSA. They also reported posttraumatic intrusions at clinical levels and showed selective attention to CSA-related words. The results are consistent with the posttraumatic intrusions account of hallucinations and delusions in those with CSA and psychosis.

This study tested the importance of coping self-efficacy (CSE) perceptions and change in perceptions of CSE for recovery from motor vehicle accident (MVA) trauma. Data were collected 7 days following the accident (Time 1; n = 163), 1 month after the accident (Time 2; n = 91), and 3 months after the accident (Time 3; n = 70). Early changes in CSE (i.e., from Time 1 to Time 2) predicted posttraumatic distress at 3 months after MVA trauma, even after controlling for Time 1 or Time 2 posttraumatic distress and other trauma-related variables (i.e., accident responsibility, litigation involvement, and peritraumatic dissociation). Early changes in CSE perceptions, however, neither moderated nor mediated the effects of early posttraumatic distress (Time 1) on 3-month posttraumatic distress. Time 2 CSE levels, however, did mediate the relationship between acute posttraumatic distress (Time 1) and 3-month posttraumatic distress (Time 3). These findings highlight the importance of early interventions aimed at strengthening self-efficacy after MVA trauma. Copyright 2008 APA, all rights reserved.

To investigate the level and determinants of posttraumatic growth in Iranian cancer patients. This descriptive-correlational design study was conducted within a university-affiliated oncology hospital in Iran. A convenience sample of 450 patients with a definitive diagnosis of cancer of any type completed a demographic questionnaire and a posttraumatic growth inventory. Some disease-related information was obtained from patients' medical records. The mean of posttraumatic growth reported by participants was 76.1. There was a statistically significant association between experience of posttraumatic growth and age (r = - 0.21, P=0.001), education at university level (F = 8.9, P=0.001) and history of treatment by radiotherapy (t = 2.1, P=0.03). The findings of this study suggest that Iranian cancer patients experience a moderate to high level of posttraumatic growth and confirm the hypothesis that the level of posttraumatic growth in non-Western cancer patients is more than that of Western cancer patients. Although, assessing the reasons for this difference needs more investigations.

Research has suggested that social support can shape posttraumatic cognitions and PTSD. However, research has yet to compare the influence of separate domains of support on posttraumatic cognitions. Multiple-group path analysis was used to examine a model in a sample of 170 victims of intimate partner violence and 208 motor vehicle accident victims in which support from friends, family, and a close other were each predicted to influence posttraumatic cognitions, which were in turn predicted to influence PTSD. Analyses revealed that support from family and friends were each negatively correlated with posttraumatic cognitions, which in turn were positively associated with PTSD. Social support from a close other was not associated with posttraumatic cognitions. No significant differences in the model were found between trauma groups. Findings identify which relationships are likely to influence posttraumatic cognitions and are discussed with regard to interpersonal processes in the development and maintenance of PTSD.

Place versus response learning in fish: a comparison between species.
McAroe, Claire L; Craig, Cathy M; Holland, Richard A
2016-01-01
Place learning is thought to be an adaptive and flexible facet of navigation. Due to the flexibility of this learning, it is thought to be more complex than the simpler strategies such as learning a particular route or navigating through the use of cues. Place learning is crucial in a familiar environment as it allows an individual to successfully navigate to the same endpoint, regardless of where in the environment the journey begins. Much of the research to date focusing on different strategies employed for navigation has used human subjects or other mammals such as rodents. In this series of experiments, the spatial memory of four different species of fish (goldfish, killifish, zebrafish and Siamese fighting fish) was analysed using a plus maze set-up. Results suggest that three of the species showed a significant preference for the adoption of a place strategy during this task, whereas zebrafish showed no significant preference. Furthermore, zebrafish took significantly longer to learn the task than the other species. Finally, results suggest that zebrafish took the least amount of time (seconds) to complete trials both during training and probe.

This article addresses some of the controversies about the role of benzodiazepines in the treatment of posttraumatic stress disorder. Benzodiazepines have been admonished in treatment guidelines for posttraumatic stress disorder, but this is based on very little solid evidence. Although benzodiazepines do not seem to be effective in the treatment of the core posttraumatic stress disorder symptoms, their careful use as adjunctive agents for the symptoms such as anxiety and sleep disturbance may be useful. Future research needs to identify predictors of improved treatment outcomes in posttraumatic stress disorder with use of benzodiazepines.

Sharp wave ripples during learning stabilize hippocampal spatial map
Roux, Lisa; Hu, Bo; Eichler, Ronny; Stark, Eran; Buzsáki, György
2017-01-01
Cognitive representation of the environment requires a stable hippocampal map but the mechanisms maintaining map representation are unknown. Because sharp wave-ripples (SPW-R) orchestrate both retrospective and prospective spatial information, we hypothesized that disrupting neuronal activity during SPW-Rs affects spatial representation. Mice learned daily a new set of three goal locations on a multi-well maze. We used closed-loop SPW-R detection at goal locations to trigger optogenetic silencing of a subset of CA1 pyramidal neurons. Control place cells (non-silenced or silenced outside SPW-Rs) largely maintained the location of their place fields after learning and showed increased spatial information content. In contrast, the place fields of SPW-R-silenced place cells remapped, and their spatial information remained unaltered. SPW-R silencing did not impact the firing rates or the proportions of place cells. These results suggest that interference with SPW-R-associated activity during learning prevents the stabilization and refinement of the hippocampal map. PMID:28394323

Adolescents exposed to multiple forms of psychological trauma ("poly-victimization," Finkelhor et al. Child Abuse Negl 2007;31:7-26) may be at high risk for psychiatric and behavioral problems. This study empirically identifies trauma profiles in a national sample of adolescents to ascertain correlates of poly-victimization. Latent Class analyses and logistic regression analyses were used with data from the National Survey of Adolescents to identify trauma profiles and each profile's risk of posttraumatic stress disorder, major depressive disorder, substance use disorders, and delinquency involvement and deviant peer group relationships. Poly-victimization classes were also compared to classes with trauma exposure of lesser complexity. Six mutually exclusive trauma profiles (latent classes) were identified. Four classes were characterized by high likelihood of poly-victimization, including abuse victims (8%), physical assault victims (9%), and community violence victims (15.5%). Poly-victimization class members, especially abuse and assault victims, were more likely than do youth traumatized by witnessing violence or exposure to disaster/accident trauma to have psychiatric diagnosis and (independent of psychiatric diagnoses or demographics) to be involved in delinquency with delinquent peers. Poly-victimization is prevalent among adolescents and places youth at high risk for psychiatric impairment and for delinquency. Moreover, poly-victimized youths' risk of delinquency cannot be fully accounted for by posttraumatic stress disorder, depression, or substance use problems, suggesting that adolescent healthcare providers should consider poly-victimization as a risk for behavioral and legal problems even when PTSD, depression, or addiction symptoms are not clinically significant.

Combat deployment and reintegration are challenging for service members and their families. Although family involvement in mental health care is increasing in the U.S. Department of Veterans Affairs (VA) system, little is known about family members' preferences for services. This study elicited the perspectives of returning Afghanistan and Iraq war veterans with posttraumatic stress disorder and their families regarding family involvement in veterans' mental health care. Semistructured qualitative interviews were conducted with 47 veterans receiving care for posttraumatic stress disorder at the Central Arkansas Veterans Healthcare System or Oklahoma City VA Medical Center and 36 veteran-designated family members. Interviews addressed perceived needs related to veterans' readjustment to civilian life, interest in family involvement in joint veteran/family programs, and desired family program content. Interview data were analyzed using content analysis and constant comparison. Both groups strongly supported inclusion of family members in programs to facilitate veterans' postdeployment readjustment and reintegration into civilian life. Both desired program content focused on information, practical skills, support, and gaining perspective on the other's experience. Although family and veteran perspectives were similar, family members placed greater emphasis on parenting-related issues and the kinds of support they and their children needed during and after deployment. To our knowledge, this is the first published report on preferences regarding VA postdeployment reintegration support that incorporates the perspectives of returning male and female veterans and those of their families.

Growing evidence suggests that the catecholamine (CA) neurotransmitters dopamine and noradrenaline support hippocampus-mediated learning and memory. However, little is known to date about which forms of hippocampus-mediated spatial learning are modulated by CA signaling in the hippocampus. Therefore, in the current study we examined the effects of 6-hydroxydopamine-induced CA depletion in the dorsal hippocampus on two prominent forms of hippocampus-based spatial learning, that is learning of object-location associations (paired-associates learning) as well as learning and choosing actions based on a representation of the context (place learning). Results show that rats with CA depletion of the dorsal hippocampus were able to learn object-location associations in an automated touch screen paired-associates learning (PAL) task. One possibility to explain this negative result is that object-location learning as tested in the touchscreen PAL task seems to require relatively little hippocampal processing. Results further show that in rats with CA depletion of the dorsal hippocampus the use of a response strategy was facilitated in a T-maze spatial learning task. We suspect that impaired hippocampus CA signaling may attenuate hippocampus-based place learning and favor dorsolateral striatum-based response learning. Copyright © 2017 Elsevier B.V.

In China, a growing number of adolescents have experienced traumatic events that have resulted in PTSD (post-traumatic stress disorder). Post-traumatic symptoms are common psychological problems in adolescents who have experienced traumatic events. However, existing studies tend to focus on the factors influencing PTSD, such as the response styles and social support, and studies on the relationships between parenting style, resilience and post-traumatic symptoms are still rare. To analyze the relationships between parenting style, resilience and post-traumatic symptoms among adolescents in China. A cross-sectional survey was conducted from June to December 2013 in the Liaoning Province, China. N = 5765 adolescents (aged 12 to 18 years old) were ultimately chosen to participate. The Chinese version of the Essen Trauma Inventory for Kids and Juveniles (ETI-KJ), a modified version of the Parental Authority Questionnaire, and the Chinese Resilience Scale were used to estimate the post-traumatic symptoms, parenting style, and resilience, respectively. Pearson's correlations, multiple linear regression analyses and structural equation modeling (SEM) were applied to analyze the data. Of the adolescents, 39.76% (N = 2292) had been exposed to traumatic events during their lives. The prevalence of probable PTSD at the time of the interview (one-month-prevalence) was 12.65%. Parenting style and resilience were significantly associated with post-traumatic symptoms. According to the SEM, parenting style had a significant direct effect on resilience (0.70, P<0.01) and post-traumatic symptoms (-0.15, P<0.05), and resilience had a significant direct effect on the post-traumatic symptoms (-0.43, P<0.01). Furthermore, parenting style had a significant indirect effect (-0.43×0.70 = -0.30. P<0.01) on the post-traumatic symptoms through resilience. The SEM significantly explained 49% of the variance in resilience and 30% of the variance in post-traumatic symptoms. Parenting style and resilience have significant effects on adolescents' post-traumatic symptoms. Schools and social-related departments could share knowledge on the impact of parenting style with parents enabling them to improve their own parenting style and their children's resilience and ability to respond effectively to traumatic events.

With a perceptive eye cast on geoscience pedagogy for students labeled as disabled, Martinez-Álvarez makes important contributions to the existing conversation on placed-based learning. It is in our local backyards, from the corner basketball court, to the mud bank of a city lake, to the adjacent field where rocky outcrops spill down to a forgotten farmer's field, that we find rich working material for connecting self and community, moving students' out-of-school experiences that feature their cultural and linguistic knowledge, from misconceptions to "alternative conceptions." Informed by her insights regarding the learning of students whose literacy does not match conventional classroom practice, geoscience learning in the place of third space can act as a model of meaning making across the entire curriculum. In the pages that follow, I transact, both aesthetically and efferently, with Martinez-Álvarez's text as she presents her research on special ways of learning in placed-based geoscience explorations with bilingual children experiencing disabilities.
Neural correlates of object-in-place learning in hippocampus and prefrontal cortex.
Kim, Jangjin; Delcasso, Sébastien; Lee, Inah

Hippocampus and prefrontal cortex (PFC) process spatiotemporally discrete events while maintaining goal-directed task demands. Although some studies have reported that neural activities in the two regions are coordinated, such observations have rarely been reported in an object-place paired-associate (OPPA) task in which animals must learn an object-in-place rule. In this study, we recorded single units and local field potentials simultaneously from the CA1 subfield of the hippocampus and PFC as rats learned that Object A, but not Object B, was rewarded in Place 1, but not in Place 2 (vice versa for Object B). Both hippocampus and PFC are required for normal performance in this task. PFC neurons fired in association with the regularity of the occurrence of a certain type of event independent of space, whereas neuronal firing in CA1 was spatially localized for representing a discrete place. Importantly, the differential firing patterns were observed in tandem with common learning-related changes in both regions. Specifically, once OPPA learning occurred and rats used an object-in-place strategy, (1) both CA1 and PFC neurons exhibited spatially more similar and temporally more synchronized firing patterns, (2) spiking activities in both regions were more phase locked to theta rhythms, and (3) CA1-medial PFC coherence in theta oscillation was maximal before entering a critical place for decision making. The results demonstrate differential as well as common neural dynamics between hippocampus and PFC in acquiring the OPPA task and strongly suggest that both regions form a unified functional network for processing an episodic event.

Memory complaints are particularly salient among veterans who experience combat-related mild traumatic brain injuries and/or trauma exposure, and represent a primary barrier to successful societal reintegration and everyday functioning. Anecdotally within clinical practice, verbal learning and memory performance frequently appears differentially reduced versus visual learning and memory scores. We sought to empirically investigate the robustness of a verbal versus visual learning and memory discrepancy and to explore potential mechanisms for a verbal/visual performance split. Participants consisted of 103 veterans with reported history of mild traumatic brain injuries returning home from U.S. military Operations Enduring Freedom and Iraqi Freedom referred for outpatient neuropsychological evaluation. Findings indicate that visual learning and memory abilities were largely intact while verbal learning and memory performance was significantly reduced in comparison, residing at approximately 1.1 SD below the mean for verbal learning and approximately 1.4 SD below the mean for verbal memory. This difference was not observed in verbal versus visual fluency performance, nor was it associated with estimated premorbid verbal abilities or traumatic brain injury history. In our sample, symptoms of depression, but not posttraumatic stress disorder, were significantly associated with reduced composite verbal learning and memory performance. Verbal learning and memory performance may benefit from targeted treatment of depressive symptomatology. Also, because visual learning and memory functions may remain intact, these might be emphasized when applying neurocognitive rehabilitation interventions to compensate for observed verbal learning and memory difficulties.
Post-traumatic stress disorder in U.S. soldiers with post-traumatic headache.

To determine the impact of post-traumatic stress disorder (PTSD) on headache characteristics and headache prognosis in U.S. soldiers with post-traumatic headache. PTSD and post-concussive headache are common conditions among U.S. Army personnel returning from deployment. The impact of comorbid PTSD on the characteristics and outcomes of post-traumatic headache has not been determined in U.S. Army soldiers. A retrospective cohort study was conducted among 270 consecutive U.S. Army soldiers diagnosed with post-traumatic headache at a single Army neurology clinic. All subjects were screened for PTSD at baseline using the PTSD symptom checklist. Headache frequency and characteristics were determined for post-traumatic headache subjects with and without PTSD at baseline. Headache measures were reassessed 3 months after the baseline visit, and were compared between groups with and without PTSD. Of 270 soldiers with post-traumatic headache, 105 (39%) met screening criteria for PTSD. There was no significant difference between subjects with PTSD and those without PTSD with regard to headache frequency (17.2 vs 15.7 headache days per month; P = .15) or chronic daily headache (58.1% vs 52.1%; P = .34). Comorbid PTSD was associated with higher headache-related disability as measured by the Migraine Disability Assessment Score. Three months after the baseline neurology clinic visit, the number of subjects with at least 50% reduction in headache frequency was similar among post-traumatic headache cases with and without PTSD (25.9% vs 26.8%). PTSD is prevalent among U.S. Army soldiers with post-traumatic headache. Comorbid PTSD is not associated with more frequent headaches or chronic daily headache in soldiers evaluated at a military neurology clinic for chronic post-traumatic headache. Comorbid PTSD does not adversely affect short-term headache outcomes, although prospective controlled trials are needed to better assess this relationship. © 2013 American Headache Society.

To examine the prevalence of post-traumatic stress disorder symptoms and to explore the predictive factors of post-traumatic stress disorder symptoms among bereaved adolescents four years after the Yushu earthquake. On 14 April 2010, the 7·1-magnitude Yushu earthquake occurred in the high-altitude, hypoxia-prone regions primarily inhabited by ethnic minorities. Many adolescents lost their parents during the earthquake. This study examined post-traumatic stress disorder and its predictors among bereaved Tibetan adolescents four years after the trauma in China. This was a cross-sectional descriptive study. This study used a cross-sectional design with 830 bereaved adolescents. Participant demographic data included gender, age and grade, and the earthquake exposure variables included the deceased relatives, whether they were buried, injured or amputated (non-life-threatening) and whether they witnessed a burial, injury or death. The post-traumatic stress disorder Checklist-Civilian version was used to assess the symptoms and prevalence of post-traumatic stress disorder, and the Coping Style Scale assessed coping styles. The results indicated that the prevalence of post-traumatic stress disorder was 19·3%. Individuals who were buried, injured or amputated (non-life-threatening), who witnessed a burial, injury or death, who suffered severe property loss during the earthquake and who had negative coping skills were the most likely individuals to have post-traumatic stress disorder symptoms. The presence of post-traumatic stress disorder was very prevalent among adolescents four years after the Yushu earthquake. Effective mental health services should be developed to facilitate postdisaster recovery for bereaved adolescents at high risk for post-traumatic stress disorder. The findings in this study improve our understanding of post-traumatic stress disorder and related risk factors in bereaved adolescents in non-Western communities, providing useful information for rebuilding and relief work. © 2016 John Wiley & Sons Ltd.
Nursing students' post-traumatic growth, emotional intelligence and psychological resilience.
Li, Y; Cao, F; Cao, D; Liu, J
2015-06-01
Nursing students in the present sample who have experienced childhood adversity have a certain level of post-traumatic growth. If introduced into nursing curricula, emotional intelligence interventions may increase emotional coping resources and enhance social skills for nurses, which may benefit their long-term occupational health. As researchers consider personal resilience a strategy for responding to workplace adversity in nurses, resilience building should be incorporated into nursing education. This is a preliminary study that may guide future investigations of the curvilinear relationship rather than linear relationship between post-traumatic growth and positive factors in the special sample of nursing students. Resilience, emotional intelligence and post-traumatic growth may benefit nursing students' careers and personal well-being in clinical work. Developing both their emotional intelligence and resilience may assist their individual post-traumatic growth and enhance their ability to cope with clinical stress. To investigate the relationships among post-traumatic growth, emotional intelligence and psychological resilience in vocational school nursing students who have experienced childhood adversities, a cross-sectional research design with anonymous questionnaires was conducted and self-report data were analysed. The Childhood Adversities Checklist (Chinese version), Posttraumatic Growth Inventory, Emotional Intelligence Scale and the 10-item Connor-Davidson Resilience Scale were used. Survey data were collected from 202 Chinese vocational school nursing students during 2011. Post-traumatic growth was associated with emotional intelligence and psychological resilience. Results indicated a curvilinear relationship between emotional intelligence and post-traumatic growth, and between psychological resilience and post-traumatic growth. Moderate-level emotional intelligence and psychological resilience were most associated with the greatest levels of growth. The results imply that moderate resilience and emotional intelligence can help nursing students cope with adversity in their future clinical work. This study first provided preliminary data suggesting the curvilinear relationship rather than linear relationship between post-traumatic growth and positive factors in the sample of nursing students. © 2014 John Wiley & Sons Ltd.

Research shows transgender individuals experience pronounced health disparities compared with their nontransgender peers. Yet, there remains insufficient research about health differences within transgender populations. This study seeks to fill this gap by exploring how current urban/rural status is associated with lifetime diagnosis of mood disorder, alcohol dependence disorder, illicit drug abuse disorder, tobacco use, posttraumatic stress disorder, human immunodeficiency virus, and suicidal ideation or attempt among veterans with transgender-related diagnoses. This study used a retrospective review of The Department of Veterans Affairs (VA) administrative data for transgender patients who received VA care from 1997 through 2014. Transgender patients were defined as individuals that had a lifetime diagnosis of any of 4 International Classification of Diseases-9 diagnosis codes associated with transgender status. Independent multivariable logistic regression models were used to explore associations of rural status with medical conditions. Veterans with transgender-related diagnoses residing in small/isolated rural towns had increased odds of tobacco use disorder (adjusted odds ratio=1.39; 95% confidence intervals, 1.09-1.78) and posttraumatic stress disorder (adjusted odds ratio=1.33; 95% confidence intervals, 1.03-1.71) compared with their urban transgender peers. Urban/rural status was not significantly associated with other medical conditions of interest. This study contributes the first empirical investigations of how place of residence is associated with medical diagnoses among veterans with transgender-related diagnoses. The importance of place as a determinant of health is increasingly clear, but for veterans with transgender-related diagnoses this line of research is currently limited. The addition of self-reported sex identity data within VA electronic health records is one way to advance this line of research.

Granule cells in the dentate gyrus regenerate constantly in adult hippocampus and then integrate into neural circuits in the hippocampus thereby providing the neural basis for learning and memory. Promoting the neurogenesis in the hippocampus facilitates learning and memory such as spatial learning, object identification, and extinction learning. The interaction between neuronal nitric oxide synthase (nNOS) and postsynaptic density protein-95 (PSD-95) is reported to negatively regulate neurogenesis in brain, so we hypothesized that disrupting this interaction might facilitate the neurogenesis in the dentate gyrus (DG) and thus enhance the extinction memory retrieval of fear learning. We found that uncoupling the nNOS-PSD-95 complex in remote contextual fear condition promoted both neuronal proliferation and survival in the DG, contributing to an enhanced retrieval of the extinction memory. Moreover, the nNOS-PSD-95 uncoupling-induced neurogenesis may be mediated by the extracellular signal-regulated kinase (ERK) as the phosphorylation level of ERK1/2 was increased after uncoupling. These findings suggest that the nNOS-PSD-95 complex may serve as a novel target for the treatment of post-traumatic stress disorder (PTSD). Copyright © 2017 Elsevier Inc. All rights reserved.
Cholinergic regulation of fear learning and extinction.
Wilson, Marlene A; Fadel, Jim R
2017-03-01
Cholinergic activation regulates cognitive function, particularly long-term memory consolidation. This Review presents an overview of the anatomical, neurochemical, and pharmacological evidence supporting the cholinergic regulation of Pavlovian contextual and cue-conditioned fear learning and extinction. Basal forebrain cholinergic neurons provide inputs to neocortical regions and subcortical limbic structures such as the hippocampus and amygdala. Pharmacological manipulations of muscarinic and nicotinic receptors support the role of cholinergic processes in the amygdala, hippocampus, and prefrontal cortex in modulating the learning and extinction of contexts or cues associated with threat. Additional evidence from lesion studies and analysis of in vivo acetylcholine release with microdialysis similarly support a critical role of cholinergic neurotransmission in corticoamygdalar or corticohippocampal circuits during acquisition of fear extinction. Although a few studies have suggested a complex role of cholinergic neurotransmission in the cellular plasticity essential for extinction learning, more work is required to elucidate the exact cholinergic mechanisms and physiological role of muscarinic and nicotinic receptors in these fear circuits. Such studies are important for elucidating the role of cholinergic neurotransmission in disorders such as posttraumatic stress disorder that involve deficits in extinction learning as well as for developing novel therapeutic approaches for such disorders. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Military veterans have higher rates of suicidality and completed suicides compared to the general population. Previous research has demonstrated suicidal behaviour is higher in US combat veterans who are younger, suffer from posttraumatic stress disorder, depression and anxiety and score lower on measures of health. However, research on predictors of suicide for Australian veterans is limited. The aim of this study was to identify significant demographic and psychological differences between veterans with posttraumatic stress disorder who had attempted suicide and those with posttraumatic stress disorder who had not, as well as determine predictors of suicide attempts within an Australian cohort. A retrospective analysis was conducted on 229 ex-service personnel diagnosed with posttraumatic stress disorder who had attended a Military Service Trauma Recovery Day Program as outpatients at Toowong Private Hospital from 2007 to 2014. Patients completed a battery of mental health self-report questionnaires assessing symptoms of posttraumatic stress disorder, alcohol use, anger, depression, anxiety and quality of life. Demographic information and self-reported history of suicide attempts were also recorded. Results indicated the average age was significantly lower, and the rates of posttraumatic stress disorder, anger, anxiety and depression symptoms were significantly higher in those veterans with history of a suicide attempt. Multivariate logistic regression analyses indicated posttraumatic stress disorder symptom severity, unemployment or total and permanent incapacity pension status significantly predicted suicide attempt history. Among a cohort of Australian veterans with posttraumatic stress disorder, psychopathology severity, unemployment and total and permanent incapacity status are significantly associated with suicidality. This study highlights the importance of early identification of posttraumatic stress disorder and psychopathology, therapeutic and social engagement, and prioritisation of tangible employment options or meaningful and goal-directed activities for veterans deemed unable to work.

Victims of motor vehicle accidents often develop post-traumatic stress disorder, which causes significant social function loss. For the difficulty in treating post-traumatic stress disorder, identification of subjects at high risk for post-traumatic stress disorder is essential for providing possible intervention. This paper aims to examine the cortical structural traits related to susceptibility to post-traumatic stress disorder. To address this issue, we performed structural magnetic resonance imaging study in motor vehicle accident victims within 48 hours from the accidents. A total of 70 victims, available for both clinical and magnetic resonance imaging data, enrolled in our study. Upon completion of 6-month follow-up, 29 of them developed post-traumatic stress disorder, while 41 of them didn't. At baseline, voxelwise comparisons of cortical thickness, cortical area and cortical volume were conducted between post-traumatic stress disorder group and trauma control group. As expected, several reduced cortical volume within frontal-temporal loop were observed in post-traumatic stress disorder. For cortical thickness, no between-group differences were observed. There were three clusters in left hemisphere and one cluster in right hemisphere showing decreased cortical area in post-traumatic stress disorder patients, compared with trauma controls. Peak voxels of the three clusters in left hemisphere were separately located in superior parietal cortex, insula and rostral anterior cingulate cortex. The finding of reduced surface area of left insula and left rostral anterior cingulate cortex suggests that shrinked surface area in motor vehicle accident victims could act as potential biomarker of subjects at high risk for post-traumatic stress disorder.

The aim of this study was to examine three hypotheses: (1) adolescents who had experienced the death of a parent would report higher grief reactions than those who had lost a grandparent; (2) adolescents who experienced the death of a parent would report higher posttraumatic growth than those who had lost a grandparent; and (3) posttraumatic growth and grief reactions are positively associated. To date, no study has investigated adolescents' posttraumatic growth by their relationship with the deceased. Cross-sectional web-based survey. Participants were adolescents who had experienced the death of a parent or grandparent in the last 5 years. Participants completed the Japanese version of the Posttraumatic Growth Inventory and grief reaction items. We conducted a web-based survey during January 2014. We used Pearson product-moment correlations to examine the association between each Posttraumatic Growth Inventory domain and each grief reaction item. Differences in the relationship with the deceased for each Posttraumatic Growth Inventory and grief reaction item were compared with an independent-sample t-test. Participants (n = 124) reported grief reactions including 'I began to get frustrated at the little things' (43·5%), 'It was difficult to go to school' (41·1%) and 'I was not able to sleep at night' (33·9%). The independent t-test indicated that parentally bereaved adolescents reported higher posttraumatic growth and grief reactions than those who had lost a grandparent. Pearson's bivariate analysis showed an association between grief reactions and posttraumatic growth. Parentally bereaved adolescents reported higher posttraumatic growth and grief reactions. Nurses should ensure bereaved adolescents receive appropriate support. © 2016 John Wiley & Sons Ltd.

The objective of this study was to find risk factors in pregnancy for post-traumatic stress and depression 1 month after childbirth. Furthermore, the relation between post-traumatic stress and depression was explored. A prospective longitudinal study. Pregnant women in Linköping and Kalmar, Sweden. A total of 1224 women were assessed in pregnancy, week 12-20 and 32, as well as 1 month postpartum. Post-traumatic stress and depression after delivery were assessed 1 month postpartum. Potential risk factors were assessed in early and late pregnancy. Variables measured during pregnancy were trait anxiety, depression, fear of childbirth, childbirth-related traumatic stress, stress coping capacity, social support, parity, educational level, age, gestation week, parity, educational level, civil status, previous psychological/psychiatric counselling, and previous experience of any traumatic events. Delivery mode was assessed from the medical records. Prevalence of post-traumatic stress (criteria A, B, C, D, E, and F according to DSM-IV) and depression (Beck's depression inventory). One month postpartum, 12 (1.3%) women had post-traumatic stress (met symptom criteria B, C, and D for post-traumatic stress disorder according to Diagnostic and statistical manual of mental disorders, 4th edition [DSM-IV]). The most important risk factors in pregnancy were depression in early pregnancy (OR=16.3), severe fear of childbirth (OR=6.2), and 'pre'-traumatic stress (in view of the forthcoming delivery) in late pregnancy (OR=12.5). The prevalence of depression was 5.6%. Post-traumatic stress and depression were positively related 1 month postpartum and were predicted by mainly the same factors. Risk factors for post-traumatic stress and depression after childbirth can be assessed in early pregnancy. Post-traumatic stress and depression also seem to share the same underlying vulnerability factors.

Military personnel exposed to combat are at risk for experiencing post-traumatic distress that can progress over time following deployment. We hypothesized that progression of post-traumatic distress may be related to enhanced susceptibility to post-deployment stressors. This study aimed at examining the concept of stress sensitization prospectively in a sample of Dutch military personnel deployed in support of the conflicts in Afghanistan. In a cohort of soldiers (N = 814), symptoms of post-traumatic stress disorder (PTSD) were assessed before deployment as well as 2, 7, 14, and 26 months (N = 433; 53 %) after their return. Data were analyzed using latent growth modeling. Using multiple group analysis, we examined whether high combat stress exposure during deployment moderated the relation between post-deployment stressors and linear change in post-traumatic distress after deployment. A higher baseline level of post-traumatic distress was associated with more early life stressors (standardized regression coefficient = 0.30, p < 0.001). In addition, a stronger increase in posttraumatic distress during deployment was associated with more deployment stressors (standardized coefficient = 0.21, p < 0.001). A steeper linear increase in posttraumatic distress post-deployment (from 2 to 26 months) was predicted by more post-deployment stressors (standardized coefficient = 0.29, p < 0.001) in high combat stress exposed soldiers, but not in a less combat stress exposed group. The group difference in the predictive effect of post-deployment stressors on progression of post-traumatic distress was significant (χ²(1) = 7.85, p = 0.005). Progression of post-traumatic distress following combat exposure may be related to sensitization to the effects of post-deployment stressors during the first year following return from deployment.

What differentiates those who are able to adapt well to adverse life events (i.e., persons who are resilient) from those who are not (e.g., persons who develop post-traumatic stress symptoms)? Previous work suggests that enhanced autobiographical integration of trauma memories is associated with more severe post-traumatic stress symptoms. Extending this line of work, the present study looked at whether the integration of trauma memories, repressive coping and cognitive reactivity are related to post-traumatic stress symptomatology following negative life events among otherwise healthy young adults (N = 213). Results show that while enhanced integration of trauma memories and high levels of dissociation are related to elevated levels of post-traumatic stress, people who generally engage in repressive coping report fewer post-traumatic stress symptoms.

This study examined reported post-traumatic stress disorder symptoms in adults with poorly controlled type 2 diabetes who had no history of psychiatric diagnosis or treatment ( n = 184, M HbA1c = 9.13%, standard deviation = 1.68). Participants reported moderate to severe intensity of post-traumatic stress disorder symptoms ( M = 19.17, SD = 17.58). Together, depressive and post-traumatic stress disorder symptoms accounted for 10-40 percent of the variance in type 2 diabetes outcomes; post-traumatic stress disorder symptoms were associated with elevated diabetes distress and more frequent exercise and self-blood glucose testing (unique R 2 ~ 3%). Post-traumatic stress disorder symptoms may be overlooked in type 2 diabetes among patients without formal psychiatric diagnoses, and warrant increased attention.
Posttraumatic stress, difficulties in emotion regulation, and coping-oriented marijuana use.

In an effort to better understand factors that may explain prior findings of a positive relation between posttraumatic stress symptom severity and coping-oriented marijuana use motivation, the present study tested whether the association between posttraumatic stress symptom severity and marijuana use coping motives is mediated by difficulties in emotion regulation. Participants were 79 (39 women; M(age) = 22.29 years, SD = 6.99) community-recruited adults who reported (1) lifetime exposure to at least one posttraumatic stress disorder Criterion A traumatic event and (2) marijuana use in the past 30 days. Results indicated that difficulties in emotion regulation, as indexed by the Difficulties in Emotion Regulation Scale (Gratz & Roemer, 2004), fully mediated the association between posttraumatic stress symptom severity and marijuana use coping motives. Implications for the treatment of co-occurring posttraumatic stress and marijuana use are discussed.

This study examined predictors and health-related effects of post-traumatic stress among 129 civilian internees of the Japanese during World War II. Post-traumatic stress disorder was noted in 36.7% within the 6 months after their release and in 15.0% within the most recent 6 months. Women were more likely than men to indicate post-traumatic stress disorder within the 6 months after their release. Higher incomes were associated with lower levels of post-traumatic stress within the most recent 6 months. After controlling for demographic and internment-related factors, higher levels of post-traumatic stress were associated with poorer physical health. This association was stronger among older internees than among their younger counterparts. Implications of the findings for clinical gerontology are discussed.

to develop a comprehensive model of personal, trauma event-related and workplace-related risk factors for posttraumatic stress subsequent to witnessing birth trauma among Australian midwives. a descriptive, cross-sectional design was used. members of the Australian College of Midwives were invited to complete an online survey. the survey included items about witnessing a traumatic birth event and previous experiences of life trauma. Trauma symptoms were assessed with the Posttraumatic Stress Disorder Symptom Scale Self-Report measure. Empathy was assessed with the Interpersonal Reactivity Index. Decision authority and psychological demand in the workplace were measured with the Job Content Questionnaire. Variables that showed a significant univariate association with probable posttraumatic stress disorder were entered into a multivariate logistic regression model. 601 completed survey responses were analysed. The multivariable model was statistically significant and explained 27.7% (Nagelkerke R square) of the variance in posttraumatic stress symptoms and correctly classified 84.1% of cases. Odds ratios indicated that intention to leave the profession, a peritraumatic reaction of horror, peritraumatic feelings of guilt, and a personal traumatic birth experience were strongly associated with probable Posttraumatic Stress Disorder. risk factors for posttraumatic stress following professional exposure to traumatic birth events among midwives are complex and multi-factorial. Posttraumatic stress may contribute to attrition in midwifery. Trauma-informed care and practice may reduce the incidence of traumatic births and subsequent posttraumatic stress reactions in women and midwives providing care. Copyright © 2016 Elsevier Ltd.

Self-efficacy is assumed to promote posttraumatic adaption, and several cross-sectional studies support this notion. However, there is a lack of prospective longitudinal studies to further illuminate the temporal relationship between self-efficacy and posttraumatic stress symptoms. Thus, an important unresolved research question is whether posttraumatic stress disorder (PTSD) symptoms affect the level of self-efficacy or vice versa or whether they mutually influence each other. The present prospective longitudinal study investigated the reciprocal relationship between general self-efficacy (GSE) and posttraumatic stress symptoms in 143 physical assault victims. We used an autoregressive cross-lagged model across four assessment waves: within 4 months after the assault (T1) and then 3 months (T2), 12 months (T3) and 8 years (T4) after the first assessment. Stress symptoms at T1 and T2 predicted subsequent self-efficacy, while self-efficacy at T1 and T2 was not related to subsequent stress symptoms. These relationships were reversed after T3; higher levels of self-efficacy at T3 predicted lower levels of posttraumatic stress symptoms at T4, while posttraumatic tress symptoms at T3 did not predict self-efficacy at T4. In conclusion, posttraumatic stress symptoms may have a deteriorating effect on self-efficacy in the early phase after physical assault, whereas self-efficacy may promote recovery from posttraumatic stress symptoms over the long term.

Posttraumatic stress disorder and intimate partner violence in a women's headache center.
Gerber, Megan R; Fried, Lise E; Pineles, Suzanne L; Shipherd, Jillian C; Bernstein, Carolyn A
2012-01-01
Posttraumatic stress disorder has been linked to women's ill health, including headaches. Intimate partner violence, which may result in posttraumatic stress disorder, is often reported by women with headaches. Prior studies of intimate partner violence and headache have estimated lifetime but not 12-month prevalence. The researchers in this study examined the relationship between headache and posttraumatic stress disorder in a novel population, and estimated 12-month and lifetime prevalence rates of intimate partner violence. Patients were recruited from a women's headache center (n = 92) during 2006-07 and completed the Migraine Disability Assessment measure of headache severity. Posttraumatic stress disorder was measured using a modified Breslau scale. Twelve-month and lifetime physical intimate partner violence were measured with the Partner Violence Screen and the STaT ("slapped, threatened and throw") measure. Multivariable regression determined factors independently associated with headache severity. Among all participants, 28.3% screened positive for posttraumatic stress disorder; 9.8% and 36.9% of women endorsed recent and lifetime intimate partner violence. Posttraumatic stress disorder was strongly associated with headache severity (β = 34.12, p = 0.01). Patients reporting lifetime intimate partner violence exhibited a trend of nine additional days of disability due to headache over 90 days. Posttraumatic stress disorder and intimate partner violence occur among a sizable proportion of women referred for headache. The authors' findings reaffirm that clinicians treating women with headaches must be aware of the possibility of posttraumatic stress disorder and intimate partner violence in such patients.
Trajectories of posttraumatic growth and depreciation after two major earthquakes.
Marshall, Emma M; Frazier, Patricia; Frankfurt, Sheila; Kuijer, Roeline G

This study examined trajectories of posttraumatic growth or depreciation (i.e., positive or negative life change) in personal strength and relationships after 2 major earthquakes in Canterbury, New Zealand using group-based trajectory modeling. Participants completed questionnaires regarding posttraumatic growth or depreciation in personal strength and relationship domains 1 month after the first earthquake in September 2010 (N = 185) and 3 months (n = 156) and 12 months (n = 144) after the more severe February 2011 earthquake. Three classes of growth or depreciation patterns were found for both domains. For personal strength, most of the participants were grouped into a "no growth or depreciation" class and smaller proportions were grouped into either a "posttraumatic depreciation" or "posttraumatic growth" class. The 3 classes for relationships all reported posttraumatic growth, differing only in degree. None of the slopes were significant for any of the classes, indicating that levels of growth or depreciation reported after the first earthquake remained stable when assessed at 2 time points after the second earthquake. Multinomial logistic regression analyses examining pre- and postearthquake predictors of trajectory class membership revealed that those in the "posttraumatic growth" personal strength class were significantly younger and had significantly higher pre-earthquake mental health than those in the "posttraumatic depreciation" class. Sex was the only predictor of the relationship classes: No men were assigned to the "high posttraumatic growth" class. Implications and future directions are discussed.

Post-Traumatic Stress Disorder, Depression and Anxiety among North Korean Refugees: A Meta-Analysis.
Taylor, Benjamin Eric; Chekaluk, Eugene; Bennett, Joanne
2017-09-01
Post-traumatic stress disorder is common among North Korean refugees who have fled their country for economic, financial and humanitarian reasons. Co-morbid depression and anxiety are also common among North Korean refugees, due to the difficulties they have faced within their country and during their escape journey. Depression and anxiety complicate treatment for post-traumatic stress disorder, and lead to poorer outcomes. Thus, the aim of the present study was to provide a meta-analysis of studies investigating post-traumatic stress disorder, depression, and anxiety among North Korean refugees. Selected articles were published in English, and included measures of post-traumatic stress, and/or depression and anxiety. 10 studies were included in the depression meta-analysis, and 6 in the anxiety meta-analysis. A random-effects model revealed strong, significant associations between post-traumatic stress and depression, r=0.63, 95% CI (0.51, 0.72), p<0.001, z=8.33, and anxiety, r=0.51, 95% CI (0.36, 0.63), p<0.001, z=6.07. The relationships between post-traumatic stress, depression and anxiety were higher among adults and those with more than five years outside of North Korea. Depression appears to be an important treatment focus for North Korean refugees with post-traumatic stress.

Despite high prevalence and concerning associated problems, little effort has been made to conceptualize the construct of posttraumatic guilt. This investigation examined the theoretical model of trauma-related guilt proposed by Kubany and Watson (2003). This model hypothesizes that emotional and physical distress related to trauma memories partially mediates the relationship between guilt cognitions and posttraumatic guilt. Using path analysis, this investigation (a) empirically evaluated relationships hypothesized in Kubany and Watson's model, and (b) extended this conceptualization by evaluating models whereby guilt cognitions, distress, and posttraumatic guilt were related to posttraumatic stress disorder (PTSD) symptoms depression symptom severity. Participants were male U.S. Iraq and Afghanistan veterans (N = 149). Results yielded a significant indirect effect from guilt cognitions to posttraumatic guilt via distress, providing support for Kubany and Watson's model (β = .14). Findings suggested distress may be the strongest correlate of PTSD symptoms (β = .47) and depression symptoms (β = .40), and that guilt cognitions may serve to intensify the relationship between distress and posttraumatic psychopathology. Research is needed to evaluate whether distress specific to guilt cognitions operates differentially on posttraumatic guilt when compared to distress more broadly related to trauma memories.

Seizures and the Role of Anticonvulsants After Traumatic Brain Injury.
Zimmermann, Lara L; Diaz-Arrastia, Ramon; Vespa, Paul M
2016-10-01
Posttraumatic seizures are a common complication of traumatic brain injury. Posttraumatic epilepsy accounts for 20% of symptomatic epilepsy in the general population and 5% of all epilepsy. Early posttraumatic seizures occur in more than 20% of patients in the intensive care unit and are associated with secondary brain injury and worse patient outcomes. Most posttraumatic seizures are nonconvulsive and therefore continuous electroencephalography monitoring should be the standard of care for patients with moderate or severe brain injury. The literature shows that posttraumatic seizures result in secondary brain injury caused by increased intracranial pressure, cerebral edema and metabolic crisis. Copyright © 2016 Elsevier Inc.

A System Computational Model of Implicit Emotional Learning
Puviani, Luca; Rama, Sidita
2016-01-01
Nowadays, the experimental study of emotional learning is commonly based on classical conditioning paradigms and models, which have been thoroughly investigated in the last century. Unluckily, models based on classical conditioning are unable to explain or predict important psychophysiological phenomena, such as the failure of the extinction of emotional responses in certain circumstances (for instance, those observed in evaluative conditioning, in post-traumatic stress disorders and in panic attacks). In this manuscript, starting from the experimental results available from the literature, a computational model of implicit emotional learning based both on prediction errors computation and on statistical inference is developed. The model quantitatively predicts (a) the occurrence of evaluative conditioning, (b) the dynamics and the resistance-to-extinction of the traumatic emotional responses, (c) the mathematical relation between classical conditioning and unconditioned stimulus revaluation. Moreover, we discuss how the derived computational model can lead to the development of new animal models for resistant-to-extinction emotional reactions and novel methodologies of emotions modulation.

Comorbid Post-Traumatic Stress Disorder and Opioid Dependence.
Patel, Rikinkumar S; Elmaadawi, Ahmed; Nasr, Suhayl; Haskin, John
2017-09-03
Post-traumatic stress disorder (PTSD) is predominant amongst individuals addicted to opioids and obscures the course of illness and the treatment outcome. We report the case of a patient with major depressive disorder and opioid dependence, who experienced post-traumatic stress disorder symptoms during a recent visit to the inpatient unit. The similarity of symptoms between post-traumatic stress disorder and opioid dependence is so high that, sometimes, it is a challenge to differentiate between these conditions. Since opioid withdrawal symptoms mimic hyper vigilance, this results in an exaggeration of the response of patients with post-traumatic stress disorder. This comorbidity is associated with worse health outcomes, as its pathophysiology involves a common neurobiological circuit. Opioid substitution therapy and psychotherapeutic medications in combination with evidence-based cognitive behavioral therapy devised for individuals with comorbid post-traumatic stress disorder and opioid dependence may improve treatment outcomes in this population. Therefore, we conclude that the screening for post-traumatic stress disorder in the opioid-abusing population is crucial. To understand the underlying mechanisms for this comorbidity and to improve the treatment response, further research should be encouraged.

BACKGROUND Trauma survivors with posttraumatic stress disorder (PTSD) report heightened physiological responses to a wide range of stimuli. It has been suggested that associative learning and stimulus generalization play a key role in the development of these symptoms. Some studies have found that trauma survivors with PTSD show greater physiological responses to individualized trauma reminders in the initial weeks after trauma than those without PTSD. This study investigated whether heart rate and skin conductance responses (HRR, SCR) to standardized trauma-related pictures at 1 month after the trauma predict chronic PTSD. METHOD Survivors of motor vehicle accidents or physical assaults (N=166) watched standardized trauma-related, generally threatening and neutral pictures at 1 month post- trauma while their HRR and SCR were recorded. PTSD symptoms were assessed with structured clinical interviews at 1 and 6 months; self-reports of fear responses and dissociation during trauma were obtained soon after the trauma. RESULTS At 1 month, trauma survivors with PTSD showed greater HRR to trauma-related pictures than those without PTSD, but not to general threat or neutral pictures. HRR to trauma-related pictures predicted PTSD severity at 1 and 6 months, and were related to fear and dissociation during trauma. SCR was not related to PTSD. CONCLUSION HRR to standardized trauma reminders at 1 month after the trauma differentiate between trauma survivors with and without PTSD, and predict chronic PTSD. Results are consistent with a role of associative learning in PTSD and suggest that early stimulus generalization may be an indicator of risk for chronic PTSD. PMID:20124426

Post-traumatic stress disorder (PTSD) is a common psychiatric disease following exposure to a severe traumatic event or physiological stress, yet the precise mechanisms underlying PTSD remains largely to be determined. Using an animal model of PTSD induced by a single prolonged stress (SPS), we assessed the role of hippocampal nicotinamide adenosine dinucleotide phosphate (NADPH) oxidase 2 (NOX2) and parvalbumin (PV) interneurons in the development of PTSD symptoms. In the present study, behavioral tests were performed by the open field (day 13 after SPS) and fear conditioning tests (days 13 and 14 after SPS). For the interventional study, rats were chronically treated with a NADPH oxidase inhibitor apocynin either by early or delayed administration. The levels of tumor necrosis factor-alpha, interleukin (IL)-1β, IL-6, IL-10, malondialdehyde, superoxide dismutase, NOX2, 4-hydroxynonenal, and PV in the hippocampus were measured at the indicated time points. In the present study, we showed that SPS rats displayed anxiety-like and enhanced fear learning behavior, which was accompanied by the increased expressions of malondialdehyde, IL-6, NOX2, 4-hydroxynonenal, and decreased PV expression. Notably, early but not delayed treatment with apocynin reversed all these abnormalities after SPS. In conclusion, our results provided evidence that NOX2 activation in the hippocampus, at least in part, contributes to oxidative stress and neuroinflammation, which further results in PV interneuron loss and consequent PTSD symptoms in a rat model of PTSD induced by SPS.

Posttraumatic stress symptoms (PTSS) are commonly associated with impairments in extinguishing fear to signals previously associated with danger, and also with inhibiting fear to safety signals. Previous studies indicate that PTSS are associated with low cortisol activity, and cortisol is shown to facilitate fear extinction. Few studies have examined the influence of cortisol reactivity on fear extinction in PTSS. We used a standardized fear conditioning and extinction paradigm to investigate the relationship between fear extinction and endogenous salivary cortisol activity in participants with high PTSS (n=18), trauma-exposed controls (n=33), and non-trauma-exposed controls (n=27). Skin conductance response (SCR) was used as an index of conditioned responding. Saliva samples were collected at baseline, and 20min post-fear acquisition for basal and reactive cortisol levels, respectively. PTSS participants demonstrated a slower rate of extinction learning during the early extinction phase. A moderation analysis revealed that cortisol reactivity was a significant moderator between fear inhibition to the safety signal (CS-) during early extinction and PTSS, but not to the threat signal (CS+). Specifically, this interaction was significant in two ways: (1) participants with elevated cortisol reactivity showed lower PTSS as fear inhibition improved; and (2) participants with low cortisol reactivity showed higher PTSS as fear inhibition improved. The findings of the present study show that the relationship between fear inhibition and cortisol reactivity is complex, and suggest that cortisol reactivity shapes safety signal learning in PTSS.

Predicting Posttraumatic Stress Disorder (PTSD) is a pre-requisite for targeted prevention. Current research has identified group-level risk-indicators, many of which (e.g., head trauma, receiving opiates) concern but a subset of survivors. Identifying interchangeable sets of risk indicators may increase the efficiency of early risk assessment. The study goal is to use supervised machine learning (ML) to uncover interchangeable, maximally predictive combinations of early risk indicators. Data variables (features) reflecting event characteristics, emergency department (ED) records and early symptoms were collected in 957 trauma survivors within ten days of ED admission, and used to predict PTSD symptom trajectories during the following fifteen months. A Target Information Equivalence Algorithm (TIE*) identified all minimal sets of features (Markov Boundaries; MBs) that maximized the prediction of a non-remitting PTSD symptom trajectory when integrated in a support vector machine (SVM). The predictive accuracy of each set of predictors was evaluated in a repeated 10-fold cross-validation and expressed as average area under the Receiver Operating Characteristics curve (AUC) for all validation trials. The average number of MBs per cross validation was 800. MBs' mean AUC was 0.75 (95% range: 0.67-0.80). The average number of features per MB was 18 (range: 12-32) with 13 features present in over 75% of the sets. Our findings support the hypothesized existence of multiple and interchangeable sets of risk indicators that equally and exhaustively predict non-remitting PTSD. ML's ability to increase prediction versatility is a promising step towards developing algorithmic, knowledge-based, personalized prediction of post-traumatic psychopathology.
Posttraumatic stress disorder and cognitive function: findings from the mind your heart study.

Prior studies have found that the patients with posttraumatic stress disorder (PTSD) have poorer performance on cognitive tests than patients without PTSD, but the underlying mechanisms remain unknown. We examined the association between PTSD and cognitive function in a large cohort and evaluated the role of potential biological and behavioral mediators. A cohort of 535 adult outpatients (≤ 65 years) without dementia, stroke, or other neurologic disorders was recruited from 2 Veterans Affairs medical centers between February 2008 and June 2010. PTSD was assessed with the Clinician Administered PTSD Scale (CAPS) using DSM-IV-TR criteria. Cognitive function tests included processing speed, Trails A and B, letter fluency, category fluency, and verbal learning and recognition. Linear regression was used to evaluate the association between PTSD and cognitive function test scores and to assess potential mediators of the association. For our analyses of PTSD and cognitive function, we combined 178 participants who met criteria for full PTSD and 18 who met criteria for partial PTSD and had a CAPS score > 40. After adjusting for demographics, these participants with PTSD scored significantly worse on processing speed (0.30 standard deviations [SDs], P ≤ .001), category fluency (0.23 SDs, P = .01), verbal learning (0.30 SDs, P = .001), and verbal recognition (0.18 SDs, P = .048) than those without PTSD. These associations were largely accounted for by health behaviors, vascular risk factors, and depression. In this cohort of veterans under age 65 years without known neurologic disease, patients with versus without PTSD had significantly poorer performance in several domains of cognitive function, particularly in tests involving processing speed, executive function, and learning. These cognitive deficits were largely explained by modifiable risk factors. Interventions targeted at these risk factors might minimize the impact of PTSD on cognitive decline and dementia risk as patients age. © Copyright 2013 Physicians Postgraduate Press, Inc.

Learned safety, a learning process in which a cue becomes associated with the absence of threat, is disrupted in individuals with post-traumatic stress disorder (PTSD). A bi-directional relationship exists between smoking and PTSD and one potential explanation is that nicotine-associated changes in cognition facilitate PTSD emotional dysregulation by disrupting safety associations. Therefore, we investigated whether nicotine would disrupt learned safety by enhancing fear associated with a safety cue. In the present study, C57BL/6 mice were administered acute or chronic nicotine and trained over three days in a differential backward trace conditioning paradigm consisting of five trials of a forward conditioned stimulus (CS)+ (Light) co-terminating with a footshock unconditioned stimulus followed by a backward CS- (Tone) presented 20 s after cessation of the unconditioned stimulus. Summation testing found that acute nicotine disrupted learned safety, but chronic nicotine had no effect. Another group of animals administered acute nicotine showed fear when presented with the backward CS (Light) alone, indicating the formation of a maladaptive fear association with the backward CS. Finally, we investigated the brain regions involved by administering nicotine directly into the dorsal hippocampus, ventral hippocampus, and prelimbic cortex. Infusion of nicotine into the dorsal hippocampus disrupted safety learning.

Hypnosis and the treatment of posttraumatic conditions: an evidence-based approach.
Lynn, Steven Jay; Cardeña, Etzel
2007-04-01
This article reviews the evidence for the use of hypnosis in the treatment of posttraumatic conditions including posttraumatic stress disorder and acute stress disorder. The review focuses on empirically supported principles and practices and suggests that hypnosis can be a useful adjunctive procedure in the treatment of posttraumatic conditions. Cognitive-behavioral and exposure-based interventions, which have the greatest empirical support, are highlighted, and an illustrative case study is presented.
Posttraumatic growth in post-surgical coronary artery bypass graft patients
Waight, Catherine A; Sheridan, Judith; Tesar, Peter
2015-01-01
Recent research in posttraumatic growth has been applied to people with life-threatening illnesses to optimise recovery. There is a lack of research exploring posttraumatic growth in coronary artery bypass graft patients. This article describes the recovery experience of 14 coronary artery bypass graft patients (13 males and 1 female) at their first outpatient review post-surgery. Grounded theory analysis was used to develop a model of distinct and shared pathways to growth depending on whether patients were symptomatic or asymptomatic pre-coronary artery bypass graft. Outcomes of posttraumatic growth in this sample included action-based healthy lifestyle growth and two forms of cognitive growth: appreciation of life and new possibilities. The model of posttraumatic growth developed in this study may be helpful in guiding future research into promoting posttraumatic growth and behaviour change in coronary artery bypass graft patients.

This study examines the relationship between meaning reconstruction with posttraumatic growth and depreciation in the aftermath of terrorist trauma and loss. A group of individuals (n=118) who were personally affected by the September 11, 2001 terrorist attacks were surveyed about their experiences and administered the Posttraumatic Growth Inventory and Impact of Event scales. Subjects were volunteer docents at the Tribute World Trade Center Visitor Center. Results revealed that ability to make sense of one's 9/11 experience was related to recovery but not to posttraumatic growth, whereas ability to find some benefit in the experience was related to growth. In addition, location in downtown Manhattan on September 11, 2001 was related to higher levels of posttraumatic depreciation. Findings suggest that two aspects of meaning reconstruction are differentially related to recovery and posttraumatic growth.

The aim of this study was to explore the different cognitive processes involved in the development of posttraumatic stress disorders (PTSDs) and posttraumatic growth (PTG). One year after the Yancheng tornado, 455 middle school students were assessed to study how posttraumatic cognitive change (PCC) influenced PTSD and PTG among traumatized Chinese adolescents through the role of rumination. The results indicated that intrusive rumination partly mediated the relationship between PCC and PTSD, and deliberate rumination partly mediated the relationship between PCC and PTSD and completely mediated the relationship between PCC and PTG. These results suggest that the cognitive processes of PTSD and PTG are different. Furthermore, the study also suggests that PTSD and PTG can coexist in individuals. This study may offer some suggestions for clinical practice after traumatic events. PMID:29686638

This study explored whether attachment moderated the relationship between grief and posttraumatic growth. A total of 240 Chinese adults who have lost a family member to cancer reported on their grief (Prolonged Grief Questionnaire-13; PG-13), posttraumatic growth (Posttraumatic Growth Inventory; PTGI) and attachment (Experiences in Close Relationships; ECR). The results suggested that bereaved individuals who scored high on attachment anxiety showed a substantial and positive relationship between grief and posttraumatic growth, while their less anxiously attached counterparts showed no such association. Attachment avoidance was not significantly related to the association between grief and posttraumatic growth. Findings indicated that individuals high in attachment anxiety have the potential to benefit and gain from the process of adapting to the loss. The implications of the results for relevant research and grief counseling were discussed. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Posttraumatic stress disorder and major depressive disorder are well-established risk factors for suicidal behavior. This study compared depressed suicide attempters with and without comorbid posttraumatic stress disorder with respect to additional diagnoses, global functioning, depressive symptoms, substance abuse, history of traumatic exposure, and suicidal behavior. Adult patients consecutively admitted to a general hospital after a suicide attempt were interviewed and assessed for DSM-IV diagnosis and clinical correlates. Sixty-four patients (71%) were diagnosed with depression; of them, 21 patients (32%) had posttraumatic stress disorder. There were no group differences in social adjustment, depressive symptoms, or suicidal intent. However, the group with comorbid depression and posttraumatic stress disorder had more additional Axis I diagnoses, a higher degree of childhood trauma exposure, and more often reported previous suicide attempts, non-suicidal self-harm, and vengeful suicidal motives. These findings underline the clinical importance of diagnosis and treatment of posttraumatic stress disorder in suicide attempters.

This study examined two theoretical models on the interaction between psychopathy, traumatic exposure, and lifetime posttraumatic stress in a sample of 81 male detainees. In Model 1, the interpersonal and affective features of psychopathy were assumed to protect against posttraumatic stress. In Model 2, the lifestyle and antisocial traits of psychopathy were assumed to lead to a lifestyle that increases the risk of traumatic exposure and subsequent posttraumatic stress. The authors found significant negative bivariate associations between Psychopathy Checklist-Revised (PCL-R) total, Interpersonal and Affective facet scores, and posttraumatic stress. Model 1 was confirmed, as they found the interaction between the Affective facet and traumatic exposure had a significant negative effect on posttraumatic stress. Model 2 was rejected. The authors' findings confirm that the interpersonal and affective features of psychopathy are associated with an emotional deficit and that the affective features of psychopathy are crucial for understanding the relationship between psychopathy and anxiety.

The objectives of this study were to examine differences in social participation among Veterans with spinal cord injuries/disorders with and without post-traumatic stress disorder, and determine if lower social participation was independently associated with having post-traumatic stress disorder. A cross-sectional mailed national survey was sent to a national sample of Veterans with spinal cord injuries/disorders who received prior-year Veterans Affairs healthcare. Surveys provided data on: demographics, health conditions, injury characteristics, and social participation. Analyses included bivariate comparisons, and multivariate logistic regression to determine if lower social participation was independently associated with post-traumatic stress disorder. Veterans with (vs. without) post-traumatic stress disorder (n = 896) reported lower social participation (40.2 vs. 43.9, p < 0.0001). Multivariate analyses showed that longer duration of injury (OR = 0.98, 95% CI: 0.97-1.00, p = 0.04) and white race (OR = 0.62, 95% CI: 0.38-1.01, p = 0.05) were associated with lower odds of post-traumatic stress disorder, while a greater number of health conditions (OR = 1.43, 95% CI: 1.25-1.64, p < 0.0001) was associated with greater odds. When controlling for covariates, lower social participation was independently associated with post-traumatic stress disorder (OR = 0.94, 95% CI: 0.90-0.98, p = 0.003). Results indicate post-traumatic stress disorder is associated with lower social participation in Veterans with spinal cord injuries/disorders, independent of other factors that may impact participation. Efforts to screen for and treat post-traumatic stress disorder among persons with spinal cord injuries/disorders, regardless of injury-specific factors, are needed to improve participation. Implications for Rehabilitation Individuals with spinal cord injuries/disorders often have post-traumatic stress disorder; in Veterans with spinal cord injuries/disorders this may be compounded by trauma incurred through military experiences. Social participation, an important aspect of rehabilitation and community integration following spinal cord injury or disorder, may be hindered by symptoms of post-traumatic stress disorder. Our data show that post-traumatic stress disorder is associated with lower social participation in Veterans with spinal cord injuries/disorders, independent of other factors that may impact participation. These results indicate that efforts to screen for and treat post-traumatic stress disorder among persons with spinal cord injuries/disorders, regardless of injury-specific factors, are needed to improve participation in this patient population.
Is mindfulness protective against PTSD? A neurocognitive study of 25 Tsunami disaster survivors.
Hagen, Christina; Lien, Lars; Hauff, Edvard; Heir, Trond

It has been suggested that mindfulness is a protective factor that buffers individuals from experiencing severe posttraumatic stress following exposure to a trauma. We aimed to examine the association between dispositional (trait) mindfulness and posttraumatic stress in individuals who had been exposed to the trauma of a natural disaster. A disaster group (n = 25) consisting of Norwegian tourists who survived the 2004 South East Asian tsunami at a location with high mortality rates was recruited. Dispositional mindfulness and posttraumatic stress were measured with the Five-Facet Mindfulness Questionnaire and the Impact of Event Scale-Revised Version, respectively. There was no significant association between mindfulness and posttraumatic stress. Moreover, there were no significant associations between posttraumatic stress and the mindfulness sub-facets of observing, acting with awareness, non-judging, and non-reacting. However, there was a significant positive correlation between the descriptive factor of mindfulness and IES-R total. There were no significant linear correlations between the five sub-facets of mindfulness and the three categories of posttraumatic symptoms, intrusion, avoidance and hyper-arousal. Our findings do not indicate a relationship between dispositional mindfulness and posttraumatic stress levels after exposure to a trauma, except for the descriptive sub-facet of mindfulness and here the correlation is positive and not negative as would be expected if mindfulness is a protective factor for posttraumatic stress. Future studies should investigate the relationship between mindfulness and posttraumatic stress while accounting for factors such as trauma history, type of trauma, and individual differences in traumatic stress reactions.

2015-03-01
In this contribution a key policy `tool' used in the Dutch Environmental Education and Learning for Sustainability Policy framework is introduced as a means to develop a sense of place and associated ecological mindfulness. The key elements of this tool, called the vital coalition, are described while an example of its use in practice, is analysed using a form of reflexive monitoring and evaluation. The example focuses on a multi-stakeholder learning process around the transformation of a somewhat sterile pre-school playground into an intergenerational green place suitable for play, discovery and engagement. Our analysis of the policy-framework and the case leads us to pointing out the importance of critical interventions at so-called tipping points within the transformation process and a discussion of the potential of hybrid learning in vital coalitions in strengthening ecological mindfulness. This paper does not focus on establishing an evidence base for the causality between this type of learning and a change in behavior or mindfulness among participants as a result contributing to a vital coalition but rather focusses on the conditions, processes and interventions that allow for such learning to take place in the first place.
Hippocampus-dependent place learning enables spatial flexibility in C57BL6/N mice

Spatial navigation is a fundamental capability necessary in everyday life to locate food, social partners, and shelter. It results from two very different strategies: (1) place learning which enables for flexible way finding and (2) response learning that leads to a more rigid “route following.” Despite the importance of knockout techniques that are only available in mice, little is known about mice' flexibility in spatial navigation tasks. Here we demonstrate for C57BL6/N mice in a water-cross maze (WCM) that only place learning enables spatial flexibility and relearning of a platform position, whereas response learning does not. This capability depends on an intact hippocampal formation, since hippocampus lesions by ibotenic acid (IA) disrupted relearning. In vivo manganese-enhanced magnetic resonance imaging revealed a volume loss of ≥60% of the hippocampus as a critical threshold for relearning impairments. In particular the changes in the left ventral hippocampus were indicative of relearning deficits. In summary, our findings establish the importance of hippocampus-dependent place learning for spatial flexibility and provide a first systematic analysis on spatial flexibility in mice. PMID:23293591

Migration to the UK has increased considerably, which is reflected in the diverse multicultural population which includes asylum seekers and economic migrants. Differences in ethnic and cultural values between the host and newcomer populations could impact on effective health care provision, especially in gender-biased conditions such as breast cancer. Breast cancer is rare in men and the diagnosis is often met with disbelief. This case report describes an unusual case of breast cancer in an Afghan man who is an asylum seeker of Asian ethnic origin. A focused ethnographic case study and in-depth interview was used to gain qualitative data and insight into the personal experiences of a male Afghan asylum seeker, age unknown (estimated to be in his 30s), with post-traumatic stress disorder who was electively admitted into hospital for the investigation of a suspicious lump in his left breast, which was subsequently found to be breast cancer. He was extremely reluctant to accept a breast cancer diagnosis and initially would not consent to any treatment, preferring to seek further opinion. During consultation with various members of the breast team he continually declined to accept the diagnosis and felt there was an error in the investigative protocol. Through the involvement of a Muslim nurse, fluent in Urdu and knowledgeable of the Afghan culture and religious background, we learned about his experiences and feelings; he opened up to her about his experiences in Afghanistan, detailing his experiences of trauma as a result of war, and disclosing that he had been diagnosed as having post-traumatic stress disorder by his physician. He saw breast cancer as a "woman's disease" which deeply affected his feelings of masculinity and left him feeling vulnerable. While sensitivity is undoubtedly required when diagnosing gender-biased conditions such as breast cancer in men, our experience showed this is exacerbated in ethnic minority groups where language barriers often exist and awareness of cultural differences is required. Awareness of the possibility of post-traumatic stress disorder in migrant populations from conflict-torn areas is also recommended during consultation.

Background In China, a growing number of adolescents have experienced traumatic events that have resulted in PTSD (post-traumatic stress disorder). Post-traumatic symptoms are common psychological problems in adolescents who have experienced traumatic events. However, existing studies tend to focus on the factors influencing PTSD, such as the response styles and social support, and studies on the relationships between parenting style, resilience and post-traumatic symptoms are still rare. Objectives To analyze the relationships between parenting style, resilience and post-traumatic symptoms among adolescents in China. Methods A cross-sectional survey was conducted from June to December 2013 in the Liaoning Province, China. N = 5765 adolescents (aged 12 to 18 years old) were ultimately chosen to participate. The Chinese version of the Essen Trauma Inventory for Kids and Juveniles (ETI-KJ), a modified version of the Parental Authority Questionnaire, and the Chinese Resilience Scale were used to estimate the post-traumatic symptoms, parenting style, and resilience, respectively. Pearson’s correlations, multiple linear regression analyses and structural equation modeling (SEM) were applied to analyze the data. Results Of the adolescents, 39.76% (N = 2292) had been exposed to traumatic events during their lives. The prevalence of probable PTSD at the time of the interview (one-month-prevalence) was 12.65%. Parenting style and resilience were significantly associated with post-traumatic symptoms. According to the SEM, parenting style had a significant direct effect on resilience (0.70, P<0.01) and post-traumatic symptoms (-0.15, P<0.05), and resilience had a significant direct effect on the post-traumatic symptoms (-0.43, P<0.01). Furthermore, parenting style had a significant indirect effect (-0.43×0.70 = -0.30. P<0.01) on the post-traumatic symptoms through resilience. The SEM significantly explained 49% of the variance in resilience and 30% of the variance in post-traumatic symptoms. Conclusions Parenting style and resilience have significant effects on adolescents’ post-traumatic symptoms. Schools and social-related departments could share knowledge on the impact of parenting style with parents enabling them to improve their own parenting style and their children’s resilience and ability to respond effectively to traumatic events.

Prolonged mechanical ventilation for acute medical conditions increases the risk of chronic critical illness (CCI). Close family members are confronted with the life-threatening condition of the CCI patients and are prone to develop posttraumatic stress disorder affecting their health-related quality of life (HRQL). Main aim of the present study was to investigate patient- and family-related risk factors for posttraumatic stress and decreased HRQL in family members of CCI patients. In a cross-sectional design nested within a prospective longitudinal cohort study, posttraumatic stress symptoms and quality of life were assessed in family members of CCI patients (n = 83, aged between 18 and 72 years) up to 6 months after transfer from ICU at acute care hospital to post-acute rehabilitation. Patients admitted a large rehabilitation hospital for ventilator weaning. The Posttraumatic Stress Scale-10 and the Euro-Quality of life-5D-3L were applied in both patients and their family members via telephone interview. A significant proportion of CCI patients and their family members (14.5 and 15.7 %, respectively) showed clinically relevant scores of posttraumatic stress. Both CCI patients and family members reported poorer HRQL than a normative sample. Factors independently associated with posttraumatic stress in family members were the time following ICU discharge (β = .256, 95 % confidence interval .053-.470) and the patients' diagnosis of PTSD (β = .264, 95 % confidence interval .045-.453). Perceived satisfaction with the relationship turned out to be a protective factor for posttraumatic stress in family members of CCI patients (β = -.231, 95 % confidence interval -.423 to -.015). Regarding HRQL in family members, patients' acute posttraumatic stress at ICU (β = -.290, 95 % confidence interval -.360 to -.088) and their own posttraumatic stress 3 to 6 months post-transfer (β = -.622, 95 % confidence interval -.640 to -.358) turned out to be significant predictors. Posttraumatic stress and HRQL should be routinely assessed in family members of CCI patients at regular intervals starting early at ICU. Preventive family-centered interventions are needed to improve posttraumatic stress and HRQL in both patients and their family members.
Post-traumatic stress disorder and opioid use disorder: A narrative review of conceptual models.
Danovitch, Itai
2016-01-01
Post-traumatic stress disorder is highly prevalent among individuals who suffer from opioid use disorder. Compared to individuals with opioid use disorder alone, those with post-traumatic stress disorder have a worse course of illness, occupational functioning, and physical health. The neurobiological pathways underlying each disorder overlap substantially, and there are multiple pathways through which these disorders may interact. This narrative review explores evidence underpinning 3 explanatory perspectives on comorbid post-traumatic stress disorder and opioid use disorder: The opioid susceptibility model (a.k.a.: the Self-Medication Hypothesis), the post-traumatic stress disorder susceptibility model, and the common factors model. Diagnostic implications, treatment implications, and directions for future research are discussed.

Prior research has revealed heightened risk-taking behavior among veterans with posttraumatic stress disorder (PTSD). This study examined whether the risktaking behavior is a direct outcome of the traumatic exposure or whether this relationship is mediated by posttraumatic stress symptoms. The sample was comprised of 180 traumatized Israeli reserve soldiers, who sought treatment in the wake of the Second Lebanon War. Combat exposure was indirectly associated with risk-taking behavior primarily through its relationship with posttraumatic stress symptoms. Results of the multivariate analyses depict the implication of posttraumatic stress symptoms in risk taking behavior, and the role of self-medication and of aggression in traumatized veterans.

A total of 187 flood victims from Wuhu, a Chinese city affected most severely by a flood during July 2016, were selected to complete self-report measures of traumatic exposure, feelings of safety, fear, posttraumatic negative cognition, and posttraumatic stress disorder. The results found that traumatic exposure could directly predict posttraumatic stress disorder. Besides, traumatic exposure had indirect prediction on posttraumatic stress disorder through three ways, including a one-step path of negative self-cognition, a two-step path from feelings of safety to fear, and a three-step path from feelings of safety to negative self-cognition via fear. Implications and future directions are correspondingly discussed.
Immediate response strategy and shift to place strategy in submerged T-maze.
Asem, Judith S A; Holland, Peter C
2013-12-01
A considerable amount of research has demonstrated that animals can use different strategies when learning about, and navigating within, their environment. Since the influential research of Packard and McGaugh (1996), it has been widely accepted that, early in learning, rats use a flexible dorsal hippocampal-dependent place strategy. As learning progresses, they switch to a less effortful and more automatic dorsolateral caudate-dependent response strategy. However, supporting literature is dominated by the use of appetitively motivated tasks, using food reward. Because motivation often plays a crucial role in guiding learning, memory, and behavior, we examined spatial learning strategies of rats in an escape-motivated submerged T-maze. In Experiment 1, we observed rapid learning and the opposite pattern as that reported in appetitively motivated tasks. Rats exhibited a response strategy early in learning before switching to a place strategy, which persisted over extensive training. In Experiment 2, we replicated Packard and McGaugh's (1996) observations, using the apparatus and procedures as in Experiment 1, but with food reward instead of water escape. Mechanisms for, and implications of, this motivational modulation of spatial learning strategy are considered.

This prospective study examined psychological and obstetrical predictors of enduring postpartum symptoms of depression and post-traumatic stress disorder. Contrary to prediction, prenatal fear of childbirth did not significantly predict symptoms of depression or post-traumatic stress disorder at one month postpartum, but anxiety sensitivity was an unexpected predictor that merits further investigation. Several obstetrical and neonatal variables significantly predicted symptoms of post-traumatic disorder, but not depression.
Family structure and posttraumatic stress reactions: a longitudinal study using multilevel analyses
2011-01-01
Background There is limited research on the relevance of family structures to the development and maintenance of posttraumatic stress following disasters. We longitudinally studied the effects of marital and parental statuses on posttraumatic stress reactions after the 2004 Southeast Asian tsunami and whether persons in the same households had more shared stress reactions than others. Method The study included a tourist population of 641 Norwegian adult citizens, many of them from families with children. We measured posttraumatic stress symptoms with the Impact of Event Scale-Revised at 6 months and 2 years post-disaster. Analyses included multilevel methods with mixed effects models. Results Results showed that neither marital nor parental status was significantly related to posttraumatic stress. At both assessments, adults living in the same household reported levels of posttraumatic stress that were more similar to one another than adults who were not living together. Between households, disaster experiences were closely related to the variance in posttraumatic stress symptom levels at both assessments. Within households, however, disaster experiences were less related to the variance in symptom level at 2 years than at 6 months. Conclusions These results indicate that adult household members may influence one another's posttraumatic stress reactions as well as their interpretations of the disaster experiences over time. Our findings suggest that multilevel methods may provide important information about family processes after disasters. PMID:22171549

Dissociation of spatial memory systems in Williams syndrome.

Williams syndrome (WS), a genetic deletion syndrome, is characterized by severe visuospatial deficits affecting performance on both tabletop spatial tasks and on tasks which assess orientation and navigation. Nevertheless, previous studies of WS spatial capacities have ignored the fact that two different spatial memory systems are believed to contribute parallel spatial representations supporting navigation. The place learning system depends on the hippocampal formation and creates flexible relational representations of the environment, also known as cognitive maps. The spatial response learning system depends on the striatum and creates fixed stimulus-response representations, also known as habits. Indeed, no study assessing WS spatial competence has used tasks which selectively target these two spatial memory systems. Here, we report that individuals with WS exhibit a dissociation in their spatial abilities subserved by these two memory systems. As compared to typically developing (TD) children in the same mental age range, place learning performance was impaired in individuals with WS. In contrast, their spatial response learning performance was facilitated. Our findings in individuals with WS and TD children suggest that place learning and response learning interact competitively to control the behavioral strategies normally used to support human spatial navigation. Our findings further suggest that the neural pathways supporting place learning may be affected by the genetic deletion that characterizes WS, whereas those supporting response learning may be relatively preserved. The dissociation observed between these two spatial memory systems provides a coherent theoretical framework to characterize the spatial abilities of individuals with WS, and may lead to the development of new learning strategies based on their facilitated response learning abilities. © 2017 Wiley Periodicals, Inc.

The majority of individuals with post-traumatic headache have symptoms that are indistinguishable from migraine. The overlap in symptoms amongst these individuals raises the question as to whether post-traumatic headache has a unique pathophysiology or if head trauma triggers migraine. The objective of this study was to compare brain structure in individuals with persistent post-traumatic headache (i.e. headache lasting at least 3 months following a traumatic brain injury) attributed to mild traumatic brain injury to that of individuals with migraine. Twenty-eight individuals with persistent post-traumatic headache attributed to mild traumatic brain injury and 28 individuals with migraine underwent brain magnetic resonance imaging on a 3 T scanner. Regional volumes, cortical thickness, surface area and curvature measurements were calculated from T1-weighted sequences and compared between subject groups using ANCOVA. MRI data from 28 healthy control subjects were used to interpret the differences in brain structure between migraine and persistent post-traumatic headache. Differences in regional volumes, cortical thickness, surface area and brain curvature were identified when comparing the group of individuals with persistent post-traumatic headache to the group with migraine. Structure was different between groups for regions within the right lateral orbitofrontal lobe, left caudal middle frontal lobe, left superior frontal lobe, left precuneus and right supramarginal gyrus (p < .05). Considering these regions only, there were differences between individuals with persistent post-traumatic headache and healthy controls within the right lateral orbitofrontal lobe, right supramarginal gyrus, and left superior frontal lobe and no differences when comparing the migraine cohort to healthy controls. In conclusion, persistent post-traumatic headache and migraine are associated with differences in brain structure, perhaps suggesting differences in their underlying pathophysiology. Additional studies are needed to further delineate similarities and differences in brain structure and function that are associated with post-traumatic headache and migraine and to determine their specificity for each of the headache types.

There is a growing understanding of the importance of the social factors of posttraumatic stress disorder. This study expands research on association between posttraumatic stress and social factors by introducing the measure of the acceptance of social changes and evaluating possible links between posttraumatic stress disorder symptoms and acceptance of social changes. A general population sample ( n = 778) aged from 18 to 89 years ( M = 40.2) from Lithuania participated in our study, of whom 68% reported exposure to traumatic events. Posttraumatic stress reactions were measured with the Impact of Event Scale - Revised (IES-R), and acceptance of social changes was measured with the Acceptance of Social Changes Instrument (SOCHI) developed by the authors of this study. About 8% of the participants had a potential posttraumatic stress disorder (PTSD) diagnosis. Acceptance of social changes was negatively associated with posttraumatic stress. PTSD was related to lower acceptance of social changes ( d = .61). Structural equation model (SEM) revealed the mediating role of PTSD for acceptance of social changes following trauma exposure. Findings of our study indicate that the acceptance of social changes might be an important psychosocial factor of PTSD.

This study was designed to assess whether the symptoms of posttraumatic stress mediate or moderate the relationship between political stressors and emotional and behavioral disorders in Palestinian children. It was hypothesized that (a) posttraumatic stress and worry mediate the effect of political stressors on behavioral and emotional disorders and (b) the relationship between political stressors and behavioral and emotional disorders should be attenuated for children with low levels of worry and posttraumatic stress and strengthened for children with high levels of worry and posttraumatic stress. The total sample was 1267 school age children of both sexes with a mean age of 11.97 years. Interviews were conducted with children at school. As hypothesized, the results indicated that posttraumatic stress and worry mediated and moderated the relationship between political stressors and emotional and behavioral disorders in children. Cognitive-behavioral therapy may be used to reduce the incidence of posttraumatic stress and decrease self-reported worry, somatic symptoms, general anxiety, and depression among children exposed to political trauma. Cognitive-behavioral treatment that exclusively targets excessive worry can lead to clinical change in the other interacting subsystems at the cognitive, physiological, affective and behavioral levels.
Post-traumatic stress disorder due to childbirth: the aftermath.
Beck, Cheryl Tatano
2004-01-01
Childbirth qualifies as an extreme traumatic stressor that can result in post-traumatic stress disorder. The reported prevalence of post-traumatic stress disorder after childbirth ranges from 1.5% to 6%. The aim of this phenomenologic study was to describe the essence of mothers' experiences of post-traumatic stress disorder after childbirth. The qualitative research design used for this study was descriptive phenomenology. The main recruitment approach was via the Internet through the help of Trauma and Birth Stress, a charitable trust in New Zealand. Purposive sampling was used and resulted in 38 mothers participating from the countries of New Zealand, the United States, Australia, and the United Kingdom. The participants were asked to describe their experiences with post-traumatic stress disorder after childbirth. Their stories were analyzed using Colaizzi's method of data analysis. Mothers with post-traumatic stress disorder attributable to childbirth struggle to survive each day while battling terrifying nightmares and flashbacks of the birth, anger, anxiety, depression, and painful isolation from the world of motherhood. This glimpse into the lives of mothers with post-traumatic stress disorder attributable to childbirth provides an impetus to increase research efforts in this neglected area.

Previous studies have proposed two mechanisms by which this dual diagnosis may occur: (1) when post-traumatic amnesia and retrograde amnesia are small or non-existent and (2) when non-declarative memory systems for the traumatic event are in operation. This case study demonstrates a third mechanism--"islands" of memory within post-traumatic amnesia. PMID:9010405

This study investigates the effects of six types of social support on distress and posttraumatic stress disorders in security guards who did and did not encounter a critical incident. Three types of social support were significantly related to distress and posttraumatic stress disorder: emotional support in problem situations, instrumental support, and social companionship. Emotional support in problem situations paradoxically appeared to have an aggravating effect on distress and posttraumatic stress, whereas instrumental support and social companionship had a mitigating outcome.

Since 2006, the Veterans Health Administration (VHA) has instituted policy changes and training programs to support system-wide implementation of two evidence-based psychotherapies (EBPs) for posttraumatic stress disorder (PTSD). To assess lessons learned from this unprecedented effort, we used PubMed and the PILOTS databases and networking with researchers to identify 32 reports on contextual influences on implementation or sustainment of EBPs for PTSD in VHA settings. Findings were initially organized using the exploration, planning, implementation, and sustainment framework (EPIS; Aarons et al. in Adm Policy Ment Health Health Serv Res 38:4-23, 2011). Results that could not be adequately captured within the EPIS framework, such as implementation outcomes and adopter beliefs about the innovation, were coded using constructs from the reach, effectiveness, adoption, implementation, maintenance (RE-AIM) framework (Glasgow et al. in Am J Public Health 89:1322-1327, 1999) and Consolidated Framework for Implementation Research (CFIR; Damschroder et al. in Implement Sci 4(1):50, 2009). We highlight key areas of progress in implementation, identify continuing challenges and research questions, and discuss implications for future efforts to promote EBPs in large health care systems.
Mental Health Services Required after Disasters: Learning from the Lasting Effects of Disasters
McFarlane, A. C.; Williams, Richard
2012-01-01
Disasters test civil administrations' and health services' capacity to act in a flexible but well-coordinated manner because each disaster is unique and poses unusual challenges. The health services required differ markedly according to the nature of the disaster and the geographical spread of those affected. Epidemiology has shown that services need to be equipped to deal with major depressive disorder and grief, not just posttraumatic stress disorder, and not only for victims of the disaster itself but also the emergency service workers. The challenge is for specialist advisers to respect and understand the existing health care and support networks of those affected while also recognizing their limitations. In the initial aftermath of these events, a great deal of effort goes into the development of early support systems but the longer term needs of these populations are often underestimated. These services need to be structured, taking into account the pre-existing psychiatric morbidity within the community. Disasters are an opportunity for improving services for patients with posttraumatic psychopathology in general but can later be utilized for improving services for victims of more common traumas in modern society, such as accidents and interpersonal violence.

Recent disasters in Sri Lanka: lessons learned.
Somasundaram, Daya
2013-09-01
Sri Lanka has faced several disasters in the recent past, both manmade and natural. The mental health and psychosocial consequences have been felt at the individual, family, and collective levels. Individuals developed normal distress, posttraumatic stress disorder, depression, or alcohol abuse. There were changes in family and social processes causing a tearing of the social fabric, lack of social cohesion, disconnection, mistrust, hopelessness, dependency, lack of motivation, powerlessness, and despondency. Because of the widespread nature of mental health needs, a community approach would reach the most number of people. Copyright © 2013 Elsevier Inc. All rights reserved.
Flood-conditioned place aversion as a novel non-pharmacological aversive learning procedure in mice.
Goltseker, Koral; Barak, Segev
2018-05-08
The place conditioning paradigm is an efficient, widely-used method to study mechanisms that underlie appetitive or aversive learning and memory processes. However, pharmacological agents used to induce conditioned place preference (CPP) or aversion (CPA) can per se interfere with learning and memory processing, hence confounding the results. Therefore, non-pharmacological place conditioning procedures are of high importance. Here, we introduce a novel procedure for induction of CPA in mice, by water flooding. We found that pairing a context with immersion in moderately cold shallow water resulted in aversion and avoidance of that context during a place preference test. Importantly, place aversion emerged only when mice experienced the onset of flood during conditioning training, but not when mice were placed in a compartment pre-filled with water. We also found that warm water was not sufficiently aversive to induce CPA. Moreover, CPA was observed after two or three context-flood pairings but not after one or four pairings, suggesting that moderate conditioning intensity produces optimal CPA expression. Thus, flood-induced CPA is a simple, cheap, and efficient procedure to form and measure place aversion memories in mice, using an ethologically-relevant threat.

Post-traumatic stress disorder is characterized by intrusive traumatic memories. Presently, a controversial debate is ongoing regarding whether reduced cortisol secretion in post-traumatic stress disorder promotes an automatic retrieval of trauma-associated memories. Hence, a pharmacological elevation of cortisol was proposed to decrease post-traumatic stress disorder symptoms, particularly intrusions. The present study investigated the impact of two different doses of hydrocortisone on automatic memory retrieval using a randomized, double-blind, placebo-controlled, crossover study in 30 inpatients with post-traumatic stress disorder. All participants were female and received various psychotropic medications. They were randomly assigned to one of two groups within a crossover design: they received either 1 week placebo followed by 1 week hydrocortisone 10/d, followed by 1 week placebo, followed by hydrocortisone 30 mg/d (15 participants) or 1 week hydrocortisone 30 mg/d, followed by 1 week placebo, followed by 1 week hydrocortisone 10 mg/d, followed by 1 week placebo (15 participants). The outcome measures were the frequency and the intensity of intrusions, the overall symptomatology of post-traumatic stress disorder and the general psychopathology. We did not find any differences in the frequency and the intensity of post-traumatic stress disorder-related intrusions between the 10 mg hydrocortisone, the 30 mg hydrocortisone and the placebo condition. All effect sizes for the hydrocortisone condition vs. placebo were very small. Additionally, the overall symptomatology of post-traumatic stress disorder and the general psychopathology did not differ between the hydrocortisone therapies and placebo. Our results do not show any effect of the hydrocortisone administration on intrusions in complex post-traumatic stress disorder. © The Author(s) 2015.

There is a paucity of research investigating the relationship of community-level characteristics such as collective efficacy and posttraumatic stress following disasters. We examine the association of collective efficacy with probable posttraumatic stress disorder and posttraumatic stress disorder symptom severity in Florida public health workers (n = 2249) exposed to the 2004 hurricane season using a multilevel approach. Anonymous questionnaires were distributed electronically to all Florida Department of Health personnel nine months after the 2004 hurricane season. The collected data were used to assess posttraumatic stress disorder and collective efficacy measured at both the individual and zip code levels. The majority of participants were female (80.42%), and ages ranged from 20 to 78 years (median = 49 years); 73.91% were European American, 13.25% were African American, and 8.65% were Hispanic. Using multi-level analysis, our data indicate that higher community-level and individual-level collective efficacy were associated with a lower likelihood of having posttraumatic stress disorder (OR = 0.93, CI = 0.88-0.98; and OR = 0.94, CI = 0.92-0.97, respectively), even after adjusting for individual sociodemographic variables, community socioeconomic characteristic variables, individual injury/damage, and community storm damage. Higher levels of community-level collective efficacy and individual-level collective efficacy were also associated with significantly lower posttraumatic stress disorder symptom severity (b = -0.22, p<0.01; and b = -0.17, p<0.01, respectively), after adjusting for the same covariates. Lower rates of posttraumatic stress disorder are associated with communities with higher collective efficacy. Programs enhancing community collective efficacy may be an important part of prevention practices and possibly lead to a reduction in the rate of posttraumatic stress disorder post-disaster.
Post-traumatic stress disorder in the perinatal period: A concept analysis.

To report an analysis of the concept of perinatal post-traumatic stress disorder. Prevalence of perinatal post-traumatic stress disorder is rising in the USA, with 9% of the U.S. perinatal population diagnosed with the disorder and an additional 18% being at risk for the condition. Left untreated, adverse maternal-child outcomes result in increased morbidity, mortality and healthcare costs. Concept analysis via Walker and Avant's approach. The databases Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medline, Academic Search Premier and PsychINFO were searched for articles, written in English, published between 2006-2015, containing the terms perinatal and post-traumatic stress disorder. Perinatal post-traumatic stress disorder owns unique attributes, antecedents and outcomes when compared to post-traumatic stress disorder in other contexts, and may be defined as a disorder arising after a traumatic experience, diagnosed any time from conception to 6 months postpartum, lasting longer than 1 month, leading to specific negative maternal symptoms and poor maternal-infant outcomes. Attributes include a diagnostic time frame (conception to 6 months postpartum), harmful prior or current trauma and specific diagnostic symptomatology defined in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition. Antecedents were identified as trauma (perinatal complications and abuse), postpartum depression and previous psychiatric history. Consequences comprised adverse maternal-infant outcomes. Further research on perinatal post-traumatic stress disorder antecedents, attributes and outcomes in ethnically diverse populations may provide clinicians a more comprehensive framework for identifying and treating perinatal post-traumatic stress disorder. Nurses are encouraged to increase their awareness of perinatal post-traumatic stress disorder for early assessment and intervention, and prevention of adverse maternal-infant outcomes. © 2017 John Wiley & Sons Ltd.

Posttraumatic stress disorder and childhood trauma frequently co-occur. Both are associated with abnormal neural responses to salient emotion stimuli. As childhood trauma is a risk factor for posttraumatic stress disorder, differentiating between their neurophysiological effects is necessary to elucidate the neural pathways by which childhood trauma exposure contributes to increased posttraumatic stress disorder risks. Face-specific N170 evoked response potentials for backward-masked (non-conscious) and conscious threat (fear, angry) and non-threat (happy) faces were measured in 77 adults (18-64 years old, 64% women, 78% right-handed) symptomatic for posttraumatic stress disorder. Differences in N170 peak amplitudes for fear-versus-happy and angry-versus-happy faces at bilateral temporo-occipital (T5, T6) sites were computed. The effect of cumulative exposure to childhood interpersonal trauma, other childhood trauma, adult trauma, depression and posttraumatic stress disorder symptom severity on the N170 response was assessed using hierarchical multiple regression analyses. T5 N170 peak amplitudes for non-conscious fear-versus-happy faces were inversely related to cumulative childhood interpersonal trauma after accounting for socio-demographic, clinical symptom and other trauma factors. Posttraumatic stress disorder Avoidance was positively associated with N170 peak amplitudes for non-conscious fear-versus-happy faces, primarily due to reduced N170 responsivity to happy faces. Childhood interpersonal trauma exposure is associated with reduced discrimination between fear and happy faces, while avoidance symptom severity is associated with dampened responsivity to automatically processed happy faces in posttraumatic stress disorder adults. Results are discussed in terms of the likely contributions of impaired threat discrimination and deficient reward processing during neural processing of salient emotion stimuli, to increased risks of posttraumatic stress disorder onset and chronicity in childhood interpersonal trauma-exposed adults.

Successful memory consolidation during sleep depends on healthy slow-wave and rapid eye movement sleep, and on successful transition across sleep stages. In post-traumatic stress disorder, sleep is disrupted and memory is impaired, but relations between these two variables in the psychiatric condition remain unexplored. We examined whether disrupted sleep, and consequent disrupted memory consolidation, is a mechanism underlying declarative memory deficits in post-traumatic stress disorder. We recruited three matched groups of participants: post-traumatic stress disorder (n = 16); trauma-exposed non-post-traumatic stress disorder (n = 15); and healthy control (n = 14). They completed memory tasks before and after 8 h of sleep. We measured sleep variables using sleep-adapted electroencephalography. Post-traumatic stress disorder-diagnosed participants experienced significantly less sleep efficiency and rapid eye movement sleep percentage, and experienced more awakenings and wake percentage in the second half of the night than did participants in the other two groups. After sleep, post-traumatic stress disorder-diagnosed participants retained significantly less information on a declarative memory task than controls. Rapid eye movement percentage, wake percentage and sleep efficiency correlated with retention of information over the night. Furthermore, lower rapid eye movement percentage predicted poorer retention in post-traumatic stress disorder-diagnosed individuals. Our results suggest that declarative memory consolidation is disrupted during sleep in post-traumatic stress disorder. These data are consistent with theories suggesting that sleep benefits memory consolidation via predictable neurobiological mechanisms, and that rapid eye movement disruption is more than a symptom of post-traumatic stress disorder. © 2014 European Sleep Research Society.

Given that post-traumatic headache is one of the most prevalent and long-lasting post-concussion sequelae, causes significant morbidity, and might be associated with slower neurocognitive recovery, we sought to evaluate the use of concussion screening scores in a concussion clinic population to assess for post-traumatic headache. This is a retrospective cross-sectional study of 254 concussion patients from the New York University (NYU) Concussion Registry. Data on the headache characteristics, concussion mechanism, concussion screening scores were collected and analyzed. 72% of the patients had post-traumatic headache. About half (56.3%) were women. The mean age was 35 (SD 16.2). 90 (35%) patients suffered from sport-related concussions (SRC). Daily post-traumatic headache patients had higher Sport Concussion Assessment Tool (SCAT)-3 symptom severity scores than the non-daily post-traumatic headache and the headache-free patients (50.2 [SD 28.2] vs. 33.1 [SD 27.5] vs. 21.6 SD23], p < 0.001). Patients with SRC had lower headache intensity (4.47 [SD 2.5] vs. 6.24 [SD 2.28], p < 0.001) and SCAT symptom severity scores (33.9 [SD 27.4] vs. 51.4 [SD 27.7], p < 0.001) than the other patients, but there were no differences in post-traumatic headache prevalence, frequency, and Standardized Assessment of Concussion (SAC) scores. The presence and frequency of post-traumatic headache are associated with the SCAT-3 symptom severity score, which is the most important predictor for post-concussion recovery. The SCAT-3 symptom severity score might be a useful tool to help characterize patients' post-traumatic headache.

Changes perceived as both positive (eg, posttraumatic growth [PTG]) and negative (eg, posttraumatic stress symptoms [PTSS]) have been associated with intensive Internet use among breast cancer survivors. In this multicenter study, we analyzed the role of PTG and PTSS on the amount of time spent looking for online cancer information, its content, and its psychological impact. Posttraumatic stress symptoms and PTG were assessed in 182 breast cancer survivors by using the Post-traumatic Stress Disorder Checklist and Post-traumatic Growth Inventory questionnaires. Subjects also completed a questionnaire about their behavior when looking for online illness-related information (ie, time spent, type of contents, and psychological impact). Posttraumatic stress symptoms positively correlated with the amount of time spent looking for cancer-related information, including both medical and psychosocial content. By contrast, PTG showed no relationships with the amount of time, but with a predominant search for cancer-related psychosocial information. The psychological impact of online information was associated with participants' levels of PTG and/or PTSS. Whereas PTG was related to a decrease of women's hope, PTSS was linked to the perception of being less conscious or inadequately informed about the illness, thereby increasing feelings of distress. Posttraumatic stress symptoms and PTG show relationships with the amount of time spent online, the type of information accessed online, and the psychological impact of Internet use. Health professionals should prescribe online information according to the psychological response to cancer. There is a need for professional-led online resources to provide patients with timely information as well as support sites to facilitate psychological adjustment.

Social support and self-efficacy are regarded as coping resources that may facilitate readjustment after traumatic events. The 2009 Cinchona earthquake in Costa Rica serves as an example for such an event to study resources to prevent subsequent severity of posttraumatic stress symptoms. At Time 1 (1-6 months after the earthquake in 2009), N=200 survivors were interviewed, assessing resource loss, received family support, and posttraumatic stress response. At Time 2 in 2012, severity of posttraumatic stress symptoms and general self-efficacy beliefs were assessed. Regression analyses estimated the severity of posttraumatic stress symptoms accounted for by all variables. Moderator and mediator models were examined to understand the interplay of received family support and self-efficacy with posttraumatic stress symptoms. Baseline posttraumatic stress symptoms and resource loss (T1) accounted for significant but small amounts of the variance in the severity of posttraumatic stress symptoms (T2). The main effects of self-efficacy (T2) and social support (T1) were negligible, but social support buffered resource loss, indicating that only less supported survivors were affected by resource loss. Self-efficacy at T2 moderated the support-stress relationship, indicating that low levels of self-efficacy could be compensated by higher levels of family support. Receiving family support at T1 enabled survivors to feel self-efficacious, underlining the enabling hypothesis. Receiving social support from relatives shortly after an earthquake was found to be an important coping resource, as it alleviated the association between resource loss and the severity of posttraumatic stress response, compensated for deficits of self-efficacy, and enabled self-efficacy, which was in turn associated with more adaptive adjustment 3 years after the earthquake.

Life-threatening experiences can result in the development of post-traumatic stress disorder. We have developed an animal model for post-traumatic stress disorder (PTSD) using a shuttle box in rats. In this paradigm, the rats were exposed to inescapable foot-shock stress (IS) in a shuttle box, and then an avoidance/escape task was performed in the same box 2 weeks after IS. A previous study using this paradigm revealed that environmental enrichment (EE) ameliorated avoidance/numbing-like behaviors, but not hyperarousal-like behaviors, and EE also elevated hippocampal brain-derived neurotrophic factor (BDNF) expression. However, the differential effects of EE components, i.e., running wheel (RW) or toy rotation, on PTSD-like behaviors has remained unclear. In this experiment, we demonstrated that RW, toy rotation, and EE (containing RW and toy rotation) ameliorated avoidance/numbing-like behaviors, induced learning of avoidance responses, and improved depressive-like behaviors in traumatized rats. The RW increased the hippocampal mRNA expression of neurotrophic factors, especially BDNF and glial-cell derived neurotrophic factor. Toy rotation influenced FK506 binding protein 5 mRNA expression, which is believed to be a regulator of the hypothalamic-pituitary-adrenal (HPA)-axis system, in the hippocampus and amygdala. This is the first report to elucidate the differential mechanistic effects of RW and toy rotation. The former appears to exert its effects via neurotrophic factors, while the latter exerts its effects via the HPA axis. Further studies will lead to a better understanding of the influence of environmental factors on PTSD. Copyright © 2018 Elsevier Inc. All rights reserved.

Learning strategy preference was assessed in 5XFAD mice, which carry 5 familial Alzheimer's disease (AD) mutations. Mice were sequentially trained in cued and place/spatial versions of the water maze task. After training, a strategy preference test was conducted in which mice were required to choose between the spatial location where the platform had previously been during the place/spatial training, and a visible platform in a new location. 5XFAD and non-transgenic control mice showed equivalent escape performance in both training tasks. However, in the strategy preference test, 5XFAD mice preferred a cued strategy relative to control mice. When the training sequence was presented in the reverse order (i.e., place/spatial training before cued training), 5XFAD mice showed impairments in place/spatial training, but no differences in cued training or in the strategy preference test comparing to control. Analysis of regional Aβ42 deposition in brains of 5XFAD mice showed that the hippocampus, which is involved in the place/spatial learning strategy, had the highest levels of Aβ42 and the dorsal striatum, which is involved in cued learning strategy, showed a small increase in Aβ42 levels. The effect of training protocol order on performance, and regional differences in Aβ42 deposition observed in 5XFAD mice, suggest differential functional recruitment of brain structures related to learning in healthy and AD individuals.

Determining the labor factors associated with post-traumatic stress in uniformed workers in Medellin. A cross-sectional study was made of 124 uniformed workers aged 20 to 48 years-old. A survey was made using an adults' post-traumatic stress instrument which had been validated in Medellin. Statistical analysis was carried out. Post-traumatic stress disorder risk prevalence was 52.2 %. Multivariate analysis showed that the highest risk situations were those related to previous mental health diagnosis (PR=7.67), working schedule (4.24), violent episodes (PR=3.59) and community relationships (PR=2.73). A person's current labor situation seemed to be a risk factor for developing post-traumatic stress in the target population.

The purpose of this study was to examine mental health treatment use among Vietnam Veterans with posttraumatic stress disorder and determine whether undergoing major surgery interrupted mental health treatment or increased the risk of psychiatric hospitalization. Using retrospective data from Veterans Health Administration's electronic medical record system, a total of 3320 Vietnam-era surgery patients with preoperative posttraumatic stress disorder were identified and matched 1:4 with non-surgical patients with posttraumatic stress disorder. The receipt of surgery was associated with a decline in overall mental health treatment and posttraumatic stress disorder-specific treatment 1 month following surgery but not during any subsequent month thereafter. Additionally, surgery was not associated with psychiatric admission. © The Author(s) 2014.

The authors review the literature relating hypnotizability and posttraumatic stress. Sixty-seven abstracts containing the key terms ASD, acute stress, trauma, traumatic, or PTSD in combination with either hypnotic susceptibility or hypnotizability were reviewed. Six articles were found containing data on hypnotizability and posttraumatic stress symptoms. Each of the studies showed some relation between hypnotizability and posttraumatic stress, but, in all of them, hypnotizability was measured after the potentially traumatizing event. High hypnotizability might be a risk factor for both acute and chronic posttraumatic symptoms. However, this cannot be determined until prospective studies measure hypnotizability in individuals before and after a potentially traumatizing event, perhaps by targeting populations that are at risk for experiencing trauma.
Improving Health with Science: Exploring Community-Driven Science Education in Kenya
NASA Astrophysics Data System (ADS)
Leak, Anne Emerson
This study examines the role of place-based science education in fostering student-driven health interventions. While literature shows the need to connect science with students' place and community, there is limited understanding of strategies for doing so. Making such connections is important for underrepresented students who tend to perceive learning science in school as disconnected to their experiences out of school (Aikenhead, Calabrese-Barton, & Chinn, 2006). To better understand how students can learn to connect place and community with science and engineering practices in a village in Kenya, I worked with community leaders, teachers, and students to develop and study an education program (a school-based health club) with the goal of improving knowledge of health and sanitation in a Kenyan village. While students selected the health topics and problems they hoped to address through participating in the club, the topics were taught with a focus on providing opportunities for students to learn the practices of science and health applications of these practices. Students learned chemistry, physics, environmental science, and engineering to help them address the health problems they had identified in their community. Surveys, student artifacts, ethnographic field notes, and interview data from six months of field research were used to examine the following questions: (1) In what ways were learning opportunities planned for using science and engineering practices to improve community health? (2) In what ways did students apply science and engineering practices and knowledge learned from the health club in their school, homes, and community? and (3) What factors seemed to influence whether students applied or intended to apply what they learned in the health club? Drawing on place-based science education theory and community-engagement models of health, process and structural coding (Saldana, 2013) were used to determine patterns in students' applications of their learning. Students applied learning across health topics they identified as interesting and relevant to their community: hand-washing, disease-prevention, first aid, balanced diet, and water. Students' application of their learning was influenced by internal, external, and relational factors with the community, science education factors, and cultural factors. Some factors, which may have been barriers for students to apply their learning, were turned into supports via bridging strategies used by the students and teacher. Bridging strategies allowed students to connect between their place and science in meaningful ways in the classroom. These strategies were critical in bringing students' place into the classroom and enabling students to apply their learning toward place. The model resulting from the identified factors informed existing models for sociocultural considerations in community-based health interventions. The community-engagement applied practices of science (CAPS) model serves to conceptualize findings in this study and informs an integrated method for using community-engagement education as a stimuli for students to become cultural brokers and improve community health. In addition to focusing on teaching practices of science and encouraging students to apply their learning, this research suggests that bridging strategies can be used to connect science with a students' place in meaningful ways that serve both students and their local communities.

Depending on the exposure to traumatic stressors and combat, 20% to 50% of ex-combatants present with trauma-related disorders, and more than half of the members of armed groups have a proclivity to violence. Therefore, psychotherapeutic assistance should address both, trauma-related suffering and the lowered threshold for aggressive behaviour. Supporting the demobilization process of ex-combatants in the eastern DR-Congo, we implemented a version of Narrative Exposure Therapy adapted for Forensic Offender Rehabilitation (FORNET). In two successive dissemination stages (DS), local counsellors conducted FORNET. In DS1, they were trained by clinical experts, and in DS2, the by then experienced counsellors trained and supervised a second group of local counsellors (DS2). The training consisted of a 3-week workshop covering theoretical concepts and practical therapeutic skills. In DS1 and DS2, a total of 98 demobilizing combatants received an intervention; treatment-as-usual served as the control condition. Posttraumatic stress disorder, appetitive aggression, depression severity and drug dependence were assessed prior to the intervention and 6 and 12 months later; additionally, we assessed reintegration success. Six months post-intervention, FORNET significantly reduced Posttraumatic stress disorder symptoms but had less effect on the trait of appetitive aggression; moreover, beneficial effects were found for depression severity and drug dependence as well as for reintegration indices. Treatment gains were retained at 12 months. Individuals without previous training in psychotherapy can learn to effectively apply the brief intervention FORNET and support the demobilization process in ongoing conflicts.

In this study, we explore directly exposed terrorism survivors' mental health and health status, healthcare utilization, alcohol and tobacco use, and posttraumatic growth 18½ years postdisaster. Telephone surveys compared terrorism survivors and nonexposed community control subjects, using Hopkins Symptom Checklist, Breslau's PTSD screen, Posttraumatic Growth Inventory, and Health Status Questionnaire 12. Statistical analyses included multivariable logistic regression and linear modeling. Survivors, more than 80% injured, reported more anxiety and depression symptoms than did control subjects, with survivors' anxiety and depression associated with heavy drinking (≥5 drinks) and worse mental health and social functioning. While survivors had continued posttraumatic stress disorder symptoms (32 [23.2%] met probable posttraumatic stress disorder threshold), they also reported posttraumatic growth. Survivors had more care from physical, speech, respiratory, and occupational therapists. In this unprecedented long-term assessment, survivors' psychiatric symptoms, alcohol use, and ancillary health service utilization suggest unmet mental health and health needs. Extended recovery efforts might benefit from maximizing positive growth and coping.

There is almost no data on the role of social support and in general on posttraumatic growth among people who have missing family member(s) as result of war and who experience ambiguous loss. This study explores relationship between reported posttraumatic growth and perceived social support and social activism in community-based organizations dealing directly with issues of missing persons. Family members who reported higher levels of social support from family, friends, and important others reported significant higher levels of posttraumatic growth. Family members that reported being active in community-based organizations reported significant higher averages in posttraumatic growth scores in total and its subscales. Regression analyses indicates that factors associated posttraumatic growth were as follows: being active in community organization dealing with missing person's issues and higher levels of social support from friends and family. Findings provide insight for clinicians working with this population and psycho social experts working in postconflict contexts.

This study investigated the role of perceived stress as a possible moderating factor between posttraumatic growth (PTG) and work satisfaction. A stratified random sampling strategy was used to survey 2080 adult survivors of the 2008 Sichuan earthquake. The Posttraumatic Growth Inventory, the Job Satisfaction Index Scale and the Perceived Stress Scale were used in the assessment of the posttraumatic growth, work satisfaction and perceived stress respectively, and hierarchical multiple regression analyses were used for the analysis. The findings highlight work satisfaction as an important factor in both the prediction of posttraumatic growth and for its moderating effect on perceived stress. Some demographic characteristics, such as gender, education level, and housing condition were found to also affect the survivors' posttraumatic growth. This conclusion indicates that managers should pay closer attention to their employees' psychological state after a disaster and medical practitioners should consider survivors' work status and perceived stress when dispensing mental health care.

The aim of this prospective study was to examine the etiology of post-traumatic stress symptoms following childbirth within a transactional framework of stress. Participants were women (N = 1,499) from the Akershus Birth Cohort. These women were followed from pregnancy to 8 weeks postpartum. We modeled predisposing factors (e.g., fear of childbirth) and precipitating factors (subjective and objective birth experiences) as predictors of post-traumatic stress symptoms. Post-traumatic stress symptoms were measured by means of the Impact of Event Scale, objective birth experiences by means of birth journals, and subjective birth experiences by means of three questions. A structural equation model showed that subjective birth experiences had the highest association with post-traumatic stress symptoms. Moreover, they mediated the effect of predisposing factors and objective birth experiences. The results suggest that women's subjective birth experiences are the most important factor in the development of post-traumatic stress symptoms following childbirth.

The roles of partner attachment and perceptions of partner support were explored in relation to symptoms of posttraumatic stress and postpartum depression in couples within the first three postnatal months. Participants (n=372) were recruited within the first seven days postpartum, and completed questionnaire measures of trait anxiety, symptoms of acute posttraumatic stress, and perceptions of partner support. Postal questionnaires were completed at six weeks and three months, assessing attachment, perception of partner support, symptoms of posttraumatic stress, and postpartum depression. Two hundred and twelve couples completed all time-points. Results indicated that symptoms were significantly related within couples. Men's acute trauma symptoms predicted their partner's subsequent symptoms of posttraumatic stress. Less secure attachment and dissatisfaction with partner support were associated with higher levels of postpartum depression and posttraumatic stress. Men's and women's responses following childbirth appear to be strongly interlinked; services should target both members of the dyad. Copyright © 2011 Elsevier Ltd. All rights reserved.
Posttraumatic re-experiencing in older people: working through or covering up?
Schreuder, J N
1996-01-01
Posttraumatic re-experiencing is a key symptom of earlier psychotraumatic experiences. It is important to establish whether we are dealing with nightmares or re-enactments. Posttraumatic nightmares are an expression of intrapsychic concerns and conflicts and, in and of themselves, need not impede exploratory psychotherapy. The nightmare entails both regression to the perceptual level of a small child and reactivation of early childhood anxieties. Before it is possible to work through the psychotraumatic experiences, it is necessary to contextualize the early childhood anxieties that are so closely related to the themes and anxieties of later life. If this is not possible, it will have to be decided to resort to therapy that rather covers up the experience and explores the current significance of the posttraumatic complaints. Posttraumatic re-enactments have an isolated position in the representational world and are accompanied by hyperarousal and intense vegetative symptoms, which is why they are considered an impediment to exploratory psychotherapy. Posttraumatic re-nactments require treatment of the symptoms before subsequent exploratory psychotherapy can be considered.

Job stress and cumulative exposure to traumatic events experienced by critical care nurses can lead to psychological distress and the development of burnout syndrome and posttraumatic stress disorder. Resilience can mitigate symptoms associated with these conditions. To identify factors that affect resilience and to determine if the factors have direct or indirect effects on resilience in development of posttraumatic stress disorder. Data from 744 respondents to a survey mailed to 3500 critical care nurses who were members of the American Association of Critical-Care Nurses were analyzed. Mplus was used to analyze a mediation model. Nurses who worked in any type of intensive care unit other than the medical unit and had high scores for resilience were 18% to 50% less likely to experience post-traumatic stress disorder than were nurses with low scores. Nurses with a graduate degree in nursing were 18% more likely to experience posttraumatic stress disorder than were nurses with a bachelor's degree. Because of their effects on resilience, working in a medical intensive care unit and having a graduate degree may influence the development of posttraumatic stress disorder. Future research is needed to better understand the impact of resilience on health care organizations, development of preventive therapies and treatment of posttraumatic stress disorder for critical care nurses, and the most appropriate mechanism to disseminate and implement strategies to address posttraumatic stress disorder. ©2017 American Association of Critical-Care Nurses.

Posttraumatic stress disorder is a chronic, debilitating condition that has become a growing concern among combat veterans. Previous research suggests that posttraumatic stress disorder disrupts normal autonomic responding and may increase the risk of cardiovascular disease and mortality. Measures of heart rate variability and QT interval variability have been used extensively to characterize sympathetic and parasympathetic influences on heart rate in a variety of psychiatric populations. The objective of this study was to better understand the effects of pharmacological treatment on autonomic reactivity in posttraumatic stress disorder. A 12-week, Phase IV, prospective, open-label trial of escitalopram in veterans with combat-related posttraumatic stress disorder and comorbid depression. An outpatient mental health clinic at a Veterans Affairs Medical Center. Eleven male veterans of Operations Enduring Freedom and Iraqi Freedom diagnosed with posttraumatic stress disorder and comorbid depression. Autonomic reactivity was measured by examining heart rate variability and QT interval variability. Treatment safety and efficacy were also evaluated pre- and post-treatment. We observed a reduction in posttraumatic stress disorder and depression symptoms from pre- to post-treatment, and escitalopram was generally well tolerated in our sample. In addition, we observed a decrease in high frequency heart rate variability and an increase in QT variability, indicating a reduction in cardiac vagal function and heightened sympathetic activation. These findings suggest that escitalopram treatment in patients with posttraumatic stress disorder and depression can trigger changes in autonomic reactivity that may adversely impact cardiovascular health.

This study examined somatic, psychological, and cognitive functioning of subjects with posttraumatic headache in comparison with multiple control groups. Posttraumatic headache is not as widely studied as other forms of headache (eg, tension-type, migraine). Previous research has suggested poor psychological functioning in patients with posttraumatic headache in comparison with other groups of patients with pain; however, this group has yet to be compared with a group of persons who have experienced trauma but are headache-free. Nineteen subjects with posttraumatic headache were studied, with full assessments available for 14 participants. Comparison groups, containing 16 participants each, included another headache group, a nonheadache group, and a trauma (motor vehicle accident) survivor nonheadache group. Participants completed several measures assessing somatic, psychological, and cognitive functioning. Findings revealed that the posttraumatic headache group exhibited significantly poorer functioning than the comparison groups on several measures including the Psychosomatic Symptom Checklist, Postconcussion Syndrome Checklist, axis II psychiatric diagnoses, Minnesota Multiphasic Personality Inventory, and the Daily Hassles Scale (frequency and total). Additionally, they scored higher on the following: number of axis I psychiatric diagnoses, the Daily Hassles Scale (intensity), Beck Depression Inventory, State-Trait Anxiety Inventory, and State-Trait Anger Expression Inventory. The posttraumatic headache group was similar to the other trauma group on the Posttraumatic Stress Disorder Symptom Checklist and the Life-Trauma Checklist. This study confirmed the distress seen in this understudied population of persons with headache and highlights areas of focus for proper assessment and treatment of those with headache and who have had an accident.
Junior doctors' guide to portfolio learning and building.
Kitchen, Mark
2012-10-01
A portfolio is a collection of evidence supporting an individual's achievement of competencies and learning outcomes. The material included in the portfolio must be reflected upon, as reflection provides the evidence that learning has taken place. Portfolio learning is important for two principal reasons: assessment of the trainee, and for lifelong learning and reflection. The ability of a portfolio to be used for both summative and formative assessment makes it a flexible and robust assessment method. A portfolio also demonstrates reflection and lifelong learning abilities. Reflective learning is key to postgraduate medical education: it is part of both the Foundation Programme curriculum and General Medical Council guidance on best practice. To ensure correct learning outcomes are identified and evidenced, the curriculum programme must be referred to and an educational supervisor should be consulted. Once identified, it is necessary to: identify how these outcomes can be met (learning needs); decide what needs to be done to meet these needs; reflect on what has been done; and evidence what has been done in the portfolio. Evidence could include written feedback, certificates of course completion, online learning modules, etc. A learning portfolio is a necessary tool for every postgraduate medical trainee. The portfolio serves to record and evidence all learning that has taken place, and thereon acts as a guide for future learning needs. The key process to portfolio building and learning is the provision of evidence by reflecting upon the learning that has taken place. © Blackwell Publishing Ltd 2012.

Although practitioners and researchers have considered children's television-based terrorism exposure, Internet-based exposure has not been sufficiently examined. We examined the scope and correlates of children's Internet-based exposure following the Boston Marathon bombing among Boston-area youth (N=460; 4-19 years), and the potential moderating role of age. Further exploratory analyses examined patterns of caregiver attempts to regulate child Internet exposure. Caregivers reported on child Internet-based and direct exposure to traumatic bombing-related events, and youth posttraumatic stress (PTS). Online youth consumed on average over two daily hours of Internet coverage, and roughly one-third consumed over three daily hours of coverage. Internet exposure was particularly high among children over 12. Greater Internet-based exposure was associated with PTS, and 12-15 year olds were particularly vulnerable. Further exploratory analyses found that although most caregivers reported believing media exposure can cause children further trauma, a considerable proportion of caregivers made no attempt to restrict or regulate their child's Internet-based exposure. These findings help practitioners clarify forms of indirect exposure that can place youth at risk following terrorism. Future work is needed to examine the important roles caregivers play as media regulators and as promoters of child coping and media literacy following terrorism.

Modern international military deployments in austere environments (i.e., Iraq and Afghanistan) place considerable physiological demands on soldiers. Significant physiological challenges exist: maintenance of physical fitness and body composition, rigors of external load carriage, environmental extremes (heat, cold, and altitude), medical illnesses, musculoskeletal injuries, traumatic brain injuries, post-traumatic stress disorder, and environmental exposure hazards (i.e., burn pits, vehicle exhaust, etc.). To date there is very little published research and no comprehensive reviews on the physiological effects of deployments. The purpose of this paper is to overview what is currently known from the literature related mainly to current military conflicts with regard to the challenges and consequences from deployments. Summary findings include: (1) aerobic capacity declines while muscle strength, power and muscular endurance appear to be maintained, (2) load carriage continues to tax the physical capacities of the Soldier, (3) musculoskeletal injuries comprise the highest proportion of all injury categories, (4) environmental insults occur from both terrestrial extremes and pollutant exposure, and (5) post-deployment concerns linger for traumatic brain injury and post-traumatic stress disorder. A full understanding of these responses will assist in identifying the most effective risk mitigation strategies to ensure deployment readiness and to assist in establishment of military employment standards.

Many children in the child welfare system (CWS) have histories of recurrent interpersonal trauma perpetrated by caregivers early in life often referred to as complex trauma. Children in the CWS also experience a diverse range of reactions across multiple areas of functioning that are associated with such exposure. Nevertheless, few CWSs routinely screen for trauma exposure and associated symptoms beyond an initial assessment of the precipitating event. This study examines trauma histories, including complex trauma exposure (physical abuse, sexual abuse, emotional abuse, neglect, domestic violence), posttraumatic stress, and behavioral and emotional problems of 2,251 youth (age 0 to 21; M = 9.5, SD = 4.3) in foster care who were referred to a National Child Traumatic Stress Network site for treatment. High prevalence rates of complex trauma exposure were observed: 70.4% of the sample reported at least two of the traumas that constitute complex trauma; 11.7% of the sample reported all 5 types. Compared to youth with other types of trauma, those with complex trauma histories had significantly higher rates of internalizing problems, posttraumatic stress, and clinical diagnoses, and differed on some demographic variables. Implications for child welfare practice and future research are discussed.

Sleep Deprivation Disrupts Recall of Conditioned Fear Extinction.
Straus, Laura D; Acheson, Dean T; Risbrough, Victoria B; Drummond, Sean P A
2017-03-01
Learned fear is crucial in the development and maintenance of posttraumatic stress disorder (PTSD) and other anxiety disorders, and extinction of learned fear is necessary for response to exposure-based treatments. In humans, research suggests disrupted sleep impairs consolidation of extinction, though no studies have examined this experimentally using total sleep deprivation. Seventy-one healthy controls underwent a paradigm to acquire conditioned fear to a visual cue. Twenty-four hours after fear conditioning, participants underwent extinction learning. Twenty-four hours after extinction learning, participants underwent extinction recall. Participants were randomized to three groups: 1) well-rested throughout testing ("normal sleep"; n = 21); 2) 36 hours total sleep deprivation before extinction learning ("pre-extinction deprivation"; n = 25); or 3) 36 hours total sleep deprivation after extinction learning and before extinction recall ("post-extinction deprivation"; n = 25). The groups were compared on blink EMG reactivity to the condition stimulus during extinction learning and recall. There were no differences among the three groups during extinction learning. During extinction recall, the pre-extinction deprivation group demonstrated significantly less extinction recall than the normal sleep group. There was no significant difference between the normal sleep and post-extinction deprivation group during extinction recall. Results indicated sleep deprivation prior to extinction training significantly disrupts extinction recall. These findings suggest that (1) sleep deprivation in the immediate aftermath of trauma could be a potential contributor to PTSD development and maintenance via interference with natural extinction processes and (2) management of sleep symptoms should be considered during extinction-based therapy.
Behavioral aspects of trauma in children and youth.

Trauma is prevalent in the lives of children. It derives from many sources, and, depending on its characteristics, can produce transient or enduring and devastating consequences. Early trauma, if left untreated, can set the stage for chronic deficits in the behavioral repertoires of affected children, and thus shape personality development. Additionally, when trauma is repetitive and chronic, the developing brain may be affected in ways that impede otherwise effective intervention. Yet diagnosing traumatic stress in children requires a departure from exclusively adult-like considerations and attention must be devoted to the ongoing developmental processes. Trauma-associated clinical features in children are sharply distinct from those that are associated with adult traumatization and must be taken into account from screening and diagnosis through treatment and outcome evaluation. We suggest that a learning foundation for symptom development will best assist the identification and selection of efficacious treatments. Pediatricians should make use of validated screening procedures that effectively identify affected children to facilitate timely referral and ongoing monitoring of treatment outcomes for their patients. A representative list of such instruments can be found in Table 1. With respect to hospital-based trauma work, we suggest the following recommendations: Professionals must be alert to the presence of acute stress symptoms in any child or parent after all injury incidents. These symptoms may occur in any injured child regardless of age, gender, injury severity, mechanism of injury, or length of time since injury. Certain mechanisms of injury, (ie, pedestrian versus motor vehicle collision), place the parent at higher risk for symptomatology. All family members, including parents and siblings, must be considered at risk for acute and long-term functional abnormalities. It is important to educate patients and family members that acute stress symptoms are common after an injury incident and are likely to resolve as the patient's injuries heal. Yet despite this, before discharge from the hospital, parents must be taught to evaluate their traumatized child's behavior, as well as their own, for any evidence of posttraumatic stress disorder. Health care providers must anticipate potential strain upon family relationships and financial resources. Parent's posttraumatic stress symptoms may result in deterioration of their own ability to support their injured child. And finally, reassessment of patient and family members should occur within the first days, at 1 to 2 weeks, 6 months, and 1 year following injury to ensure proper recovery and optimization of psychosocial function.

Osteoarthritis is a leading cause of disability whose prevalence and incidence continue to increase. History of joint injury represents an important risk factor for posttraumatic osteoarthritis and is a significant contributor to the rapidly growing percentage of the population with osteoarthritis. This review will present the epidemiology associated with posttraumatic osteoarthritis, with particular emphasis on the knee and ankle joints. It is important to understand the effect of posttraumatic osteoarthritis on the population so that sufficient resources can be devoted to countering the disease and promoting optimal long-term health for patients after joint injury.
Update on the management of post-traumatic stress disorder
Wallace, Duncan; Cooper, John
2015-01-01
Summary Post-traumatic stress disorder occurs in people exposed to life-threatening trauma. GPs may be seeing more patients with post-traumatic stress disorder as military personnel return from overseas deployments. The condition can present in various ways. To reduce the likelihood of missed or delayed diagnosis GPs can screen at-risk populations. A comprehensive assessment is recommended. Specialist referral may be required, particularly if there are other mental health problems. Trauma-focused psychological therapies should be offered as the first line of treatment for post-traumatic stress disorder. Usually 8–12 sessions are needed for a therapeutic effect. If drug treatment is needed, selective serotonin reuptake inhibitors are the first line. Other drugs used in post-traumatic stress disorder include antipsychotics, anticonvulsants and prazosin.

This study examined the unique effects of child sexual abuse simultaneously with post-traumatic stress disorder symptom clusters, problem drinking, and illicit drug use in relation to sexual revictimization in a community sample of female adult sexual assault victims. Participants (N=555) completed two surveys a year apart. Child sexual abuse predicted more post-traumatic stress disorder symptoms in adult sexual assault victims. Posttraumatic stress disorder numbing symptoms directly predicted revictimization, whereas other post-traumatic stress disorder symptoms (reexperiencing, avoidance, and arousal) were related to problem drinking, which in turn predicted revictimization. Thus, numbing symptoms and problem drinking may be independent risk factors for sexual revictimization in adult sexual assault victims, particularly for women with a history of childhood sexual abuse.

The present investigation examined the incremental predictive validity of mindfulness-based processes, indexed by the Kentucky Inventory of Mindfulness Skills, in relation to posttraumatic stress symptom severity among individuals without any axis I psychopathology. Participants included 239 adults who endorsed exposure to traumatic life events. Results indicated that the Accepting without Judgment subscale was significantly incrementally associated with posttraumatic stress symptoms; effects were above and beyond the variance accounted for by negative affectivity and number of trauma types experienced. The Acting with Awareness subscale was incrementally associated with only posttraumatic stress-relevant re-experiencing symptoms; and no other mindfulness factors were related to the dependent measures. Findings are discussed in relation to extant empirical and theoretical work relevant to mindfulness and posttraumatic stress. PMID:18834701

This preliminary study examined whether the practice of mind-body techniques decreases symptoms of posttraumatic stress in adolescents. Posttraumatic Stress Reaction Index questionnaires were collected from 139 high school students in Kosovo who participated in a 6-week program that included meditation, biofeedback, drawings, autogenic training, guided imagery, genograms, movement, and breathing techniques. Three separate programs were held approximately 2 months apart. There was no control group. Posttraumatic stress scores significantly decreased after participation in the programs. These scores remained decreased in the 2 groups that participated in the follow-up study when compared to pretest measures. These data indicate that mind-body skills groups were effective in reducing posttraumatic stress symptoms in war-traumatized high school students.

Following Hurricane Katrina, police officers in the New Orleans geographic area faced a number of challenges. This cross-sectional study examined the association between resilience, satisfaction with life, gratitude, posttraumatic growth, and symptoms of posttraumatic stress disorder in 84 male and 30 female police officers from Louisiana. Protective factors were measured using the Connor-Davidson Resilience scale, Satisfaction with Life Scale, the Gratitude Questionnaire, and the Posttraumatic Growth inventory. Symptoms of posttraumatic stress disorder were measured using the Posttraumatic Stress Disorder Checklist--Civilian (PCL-C). Potential associations were measured using linear regression and analysis of variance. Models were adjusted for age, sex, race, education, and alcohol. Mean PCL-C symptoms were 29.5 ± 14.5 for females and 27.8 ± 12.1 for males. Adjusted mean levels of PCL-C symptoms significantly decreased as quartiles of resilience (p < .001), satisfaction with life (p < .001), and gratitude (p < .001) increased. In contrast, PCL-C symptoms were not associated with posttraumatic growth in this sample. These results indicate that positive factors such as resilience, satisfaction with life, and gratitude may help mitigate symptoms of posttraumatic stress disorder. To further explore these relationships, longitudinal follow-up in a larger population would be of interest. © 2014 John Wiley & Sons, Ltd.

Posttraumatic stress is associated with increased body mass index (BMI) and rates of obesity. Black adults are at greater risk for obesity, trauma exposure, development of posttraumatic stress disorder, and comorbid sleep problems compared to White adults. Accordingly, Black adults with a history of trauma exposure may be at greater risk for elevated BMI associated with posttraumatic stress and insomnia. Multiple linear regression was used to examine race as a moderator of the relationship between posttraumatic symptoms and insomnia with BMI in a sample of Black and White trauma-exposed Veterans (N = 171), controlling for age and sex. There was a significant interaction of race with PTSD (p = 0.042) and insomnia symptoms (p = 0.045) on BMI. Simple slopes showed a significant positive association of posttraumatic stress and BMI among Black (p = 0.003), but not White Veterans (p = 0.590). Similarly, insomnia was significantly associated with greater BMI for Black (p = 0.023), but not White Veterans (p = 0.496). Posttraumatic stress and insomnia may play a particularly important role in the development of weight related health problems among Black Veterans. Early identification and treatment of these symptoms may reduce the risk of obesity among this vulnerable population.

Although intimate partner violence (IPV) has demonstrated strong associations with anxiety and posttraumatic stress, these constructs have rarely been examined simultaneously in IPV research. Gaps in knowledge remain as to their differential associations to substance use problems among IPV-victimized women. A sample of 143 community women self-reported on their current IPV victimization, mental health and substance use problems. Hierarchical entry multiple regressions were used to test for the direct and indirect effects of psychological, physical, and sexual IPV to alcohol and drug problems through anxiety and posttraumatic stress. Higher anxiety symptom severity and higher physical IPV severity were associated with greater alcohol and drug problems. Higher posttraumatic stress symptom severity was associated with greater alcohol and drug problems. Mediation analyses indicated (i) significant indirect pathways of IPV types to alcohol problems through posttraumatic stress symptom severity controlling for anxiety symptom severity and (ii) significant indirect pathways of IPV types to drug problems through anxiety symptom severity controlling for posttraumatic stress symptom severity. In examining the indirect pathways of psychological, physical, and sexual IPV to substance use problems this study highlights that anxiety and posttraumatic stress symptom severity have unique effects on alcohol and drug problems among IPV-victimized women.

Several psychological sequelae have been identified in civilian war survivors. However, little is known about the prevalence of obsessive-compulsive symptoms and their relationship to trauma in this population. Fifty-one adult civilian survivors of the Kosovo War (28 males) who had immigrated to Switzerland completed the Revised Obsessive-Compulsive Inventory Scale, the Posttraumatic Stress Diagnostic Scale and the Hopkins Symptom Checklist. Data were analysed using multiple regression analyses. Overall, 35 and 39% of the sample scored above the cut-offs for likely obsessive-compulsive disorder and posttraumatic stress disorder, respectively. Participants with high levels of posttraumatic stress symptoms were significantly more likely to have obsessive-compulsive symptoms, and vice versa. In multiple regression analysis, gender and severity of posttraumatic stress symptoms were predictors of obsessive-compulsive symptoms, whereas number of traumatic life event types and depressive symptoms were not. Given the small sample size, the results of this study need to be interpreted cautiously. Nevertheless, a surprisingly high number of participants in our study suffered from both obsessive-compulsive and posttraumatic stress symptoms, with obsessive-compulsive symptoms tending to be more pronounced in women. It remains, therefore, critical to specifically assess both obsessive-compulsive and posttraumatic stress symptoms in civilian war survivors, and to provide persons afflicted with appropriate mental health care.

Post-traumatic stress disorder is characterized by exaggerated threat response, and theoretical accounts to date have focused on impaired threat processing and dysregulated prefrontal-cortex-amygdala circuitry. Nevertheless, evidence is accruing for broad, threat-neutral sensory hyperactivity in post-traumatic stress disorder. As low-level, sensory processing impacts higher-order operations, such sensory anomalies can contribute to widespread dysfunctions, presenting an additional aetiological mechanism for post-traumatic stress disorder. To elucidate a sensory pathology of post-traumatic stress disorder, we examined intrinsic visual cortical activity (based on posterior alpha oscillations) and bottom-up sensory-driven causal connectivity (Granger causality in the alpha band) during a resting state (eyes open) and a passive, serial picture viewing state. Compared to patients with generalized anxiety disorder (n = 24) and healthy control subjects (n = 20), patients with post-traumatic stress disorder (n = 25) demonstrated intrinsic sensory hyperactivity (suppressed posterior alpha power, source-localized to the visual cortex-cuneus and precuneus) and bottom-up inhibition deficits (reduced posterior→frontal Granger causality). As sensory input increased from resting to passive picture viewing, patients with post-traumatic stress disorder failed to demonstrate alpha adaptation, highlighting a rigid, set mode of sensory hyperactivity. Interestingly, patients with post-traumatic stress disorder also showed heightened frontal processing (augmented frontal gamma power, source-localized to the superior frontal gyrus and dorsal cingulate cortex), accompanied by attenuated top-down inhibition (reduced frontal→posterior causality). Importantly, not only did suppressed alpha power and bottom-up causality correlate with heightened frontal gamma power, they also correlated with increased severity of sensory and executive dysfunctions (i.e. hypervigilance and impulse control deficits, respectively). Therefore, sensory aberrations help construct a vicious cycle in post-traumatic stress disorder that is in action even at rest, implicating dysregulated triangular sensory-prefrontal-cortex-amygdala circuitry: intrinsic sensory hyperactivity and disinhibition give rise to frontal overload and disrupt executive control, fuelling and perpetuating post-traumatic stress disorder symptoms. Absent in generalized anxiety disorder, these aberrations highlight a unique sensory pathology of post-traumatic stress disorder (ruling out effects merely reflecting anxious hyperarousal), motivating new interventions targeting sensory processing and the sensory brain in these patients. © The Author (2017).

The aim of this study was to identify the potential risk factors for the development of post-traumatic stress disorder in mothers and fathers following infant hospitalisation in the neonatal intensive care unit. The development of neonatal intensive care units has increased the survival rate of infants. However, one of the major parental problems is post-traumatic stress disorder. An observational study covered 125 parents (72 mothers and 53 fathers) of infants aged 3-12 months who were hospitalised in the neonatal intensive care unit during the neonatal period. Third-referral neonatal intensive care unit. Several standardised and self-reported research tools were used to estimate the level of post-traumatic stress symptoms (Impact Event Scale-Revised), perceived stress (Perceived Stress Scale) and coping strategies (COPE Inventory). The respondents also completed a Parent and Infant Characteristic Questionnaire. The mothers and fathers did not differ in their parental and infant characteristics. Post-traumatic stress disorder was present in 60% of the mothers and 47% of the fathers. Compared to the fathers, the mothers felt greater stress (p = .020) and presented a higher severity of post-traumatic stress disorder (p < .001). Previous miscarriages (p = .023) and the presence of chronic diseases (p = .032) were risk factors for post-traumatic stress disorder in the mothers. In the fathers, an Apgar test at 1 min after birth (p = .030) and a partner's post-traumatic stress disorder (p = .038) were related to post-traumatic stress disorder. The mothers compared to the fathers were more likely to use strategies such as: positive reinterpretation and growth, focusing on and venting of emotions, instrumental social support, religious coping and acceptance. In the fathers, the predictors included an Apgar score at 1 min after birth, a lack of congenital anomalies in the child and mental disengagement. Risk factors for post-traumatic stress disorder, as well as coping strategies, differ in women compare to men. Knowledge of risk factors for post-traumatic stress disorder, specific to men and women, may help identify the parents in whom probability of the occurrence of this disorder is increased. © 2017 John Wiley & Sons Ltd.
Clinical supervisors' perspectives on delivering work integrated learning: a survey study.
Mather, Carey A; McKay, Angela; Allen, Penny
2015-04-01
Previous research has indicated a disconnect between academic nursing programmes and workplace learning environments. Nurse supervisors and clinical practitioners have reported inadequate information and training on how to support students of nursing to learn in the clinical setting. This study aimed to investigate the level of confidence that clinical supervisors have in relation to specific components of supporting student learning in the work place. Survey of clinical nurse supervisors. Simulation-based clinical reasoning workshops. Sixty participants: fifty nine registered nurses, including nurse managers and clinical nurse educators, and one allied health professional. Survey using Likert scales and free-text questions. The findings indicated that clinicians were confident in sharing their knowledge and experience with students and making them feel welcome in the work place, they were less confident about what were the significant learnings in relation to students' academic programme. Registered nurses supervising students were experienced clinicians with many role responsibilities, which were perceived as barriers to the role of clinical supervisor. Participants reported that they would like tools to assist them with developing links to the academic programme. They considered that these tools would support student learning and remediation in the work place. This study found that the abilities of supervisors to support student learning is an identified gap impacting on work integrated learning. The results indicated the need for a professional development workshop, to enable clinical supervisors to move beyond promoting a supervision model, towards a theoretical framework for assisting and guiding students to learn. Addressing this deficit will improve growth and change in student learning in the work place. Copyright © 2015 Elsevier Ltd. All rights reserved.
Genetic disruptions of Drosophila Pavlovian learning leave extinction learning intact.
Qin, H; Dubnau, J
2010-03-01
Individuals who experience traumatic events may develop persistent posttraumatic stress disorder. Patients with this disorder are commonly treated with exposure therapy, which has had limited long-term success. In experimental neurobiology, fear extinction is a model for exposure therapy. In this behavioral paradigm, animals are repeatedly exposed in a safe environment to the fearful stimulus, which leads to greatly reduced fear. Studying animal models of extinction already has lead to better therapeutic strategies and development of new candidate drugs. Lack of a powerful genetic model of extinction, however, has limited progress in identifying underlying molecular and genetic factors. In this study, we established a robust behavioral paradigm to study the short-term effect (acquisition) of extinction in Drosophila melanogaster. We focused on the extinction of olfactory aversive 1-day memory with a task that has been the main workhorse for genetics of memory in flies. Using this paradigm, we show that extinction can inhibit each of two genetically distinct forms of consolidated memory. We then used a series of single-gene mutants with known impact on associative learning to examine the effects on extinction. We find that extinction is intact in each of these mutants, suggesting that extinction learning relies on different molecular mechanisms than does Pavlovian learning.

Present neuroimaging findings suggest two subtypes of trauma response, one characterized predominantly by hyperarousal and intrusions, and the other primarily by dissociative symptoms. The neural underpinnings of these two subtypes need to be better defined. Fourteen women with childhood abuse and the current diagnosis of dissociative amnesia or dissociative identity disorder but without posttraumatic stress disorder (PTSD) and 14 matched healthy comparison subjects underwent functional magnetic resonance imaging (fMRI) while finding their way in a virtual maze. The virtual maze presented a first-person view (egocentric), lacked any topographical landmarks and could be learned only by using egocentric navigation strategies. Participants with dissociative disorders (DD) were not impaired in learning the virtual maze when compared with controls, and showed a similar, although weaker, pattern of activity changes during egocentric learning when compared with controls. Stronger dissociative disorder severity of participants with DD was related to better virtual maze performance, and to stronger activity increase within the cingulate gyrus and the precuneus. Our results add to the present knowledge of preserved attentional and visuospatial mnemonic functioning in individuals with DD. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

How might we authentically and practically evaluate the effects of a geologic heritage place or program on public Earth science literacy? This pedagogical form of evaluation is distinct from the evaluation of a place for its geological importance, heritage value, economic or cultural impact, and so on. Best evaluation practices from the realms of formal education, informal education, and interpretation start with a coherent set of evaluable learning outcomes, ideally recapitulated in one or more 'big ideas' that capture the essential attributes of the place or program. Learning outcomes may be classified as cognitive, affective, or psychomotor. Cognitive learning outcomes in a geoheritage context are the Earth-science concepts a visitor or student would be expected to uncover through on-site or virtual exploration of the stratigraphy, structure, landforms, and processes in a place. The Earth Science Literacy Principles (ESLP), and similar literacy documents relating to atmosphere, oceans, and climate; offer a template for mapping localized concepts onto more global ones. Quantitative instruments to evaluate understanding of the ESLP are in development, and the ESLP also map directly onto measures used in formal educational assessment, notably the Next Generation Science Standards in the USA. Nongeological place meanings (a component of sense of place) may suggest other cognitive outcomes. Affective learning outcomes for visitors and students in geoheritage sites are less readily defined, but may include place attachment (also a component of sense of place), attitudes, and interest. Multiple quantitative and qualitative methods of evaluating these outcomes exist. Psychomotor learning outcomes are even muddier, but accessibility (defined by statutes) offers a potential starting point. In practice, evaluation may be conducted synchronously or asynchronously with visitors' or students' interaction with the geoheritage place or program. Evaluation programs are typically constrained by access and practicality. Synchronous methods include observation, semi-structured interviews, rapid prototyping and surveys. Asynchronous methods include interviews, surveys, and tracking. Evaluation tools may require content or instrument validation for the specific context in which they are used. Illustrative examples from evaluation of public engagement with geoheritage places (National Parks) in the Southwest USA will be offered.

Post-traumatic stress disorder (PTSD) is common among people with substance use disorders, and the comorbidity is associated with negative outcomes. We report on a randomized controlled trial comparing the effect of integrated cognitive-behavioral therapy (ICBT) plus standard care, individual addiction counseling plus standard care and standard care alone on substance use and PTSD symptoms. Three-group, multi-site randomized controlled trial. Seven addiction treatment programs in Vermont and New Hampshire, USA. Recruitment took place between December 2010 and January 2013. In this single-blind study, 221 participants were randomized to one of three conditions: ICBT plus standard care (SC) (n = 73), individual addiction counseling (IAC) plus SC (n = 75) or SC only (n = 73). One hundred and seventy-two patients were assessed at 6-month follow-up (58 ICBT; 61 IAC; 53 SC). Intervention and comparators: ICBT is a manual-guided therapy focused on PTSD and substance use symptom reduction with three main components: patient education, mindful relaxation and flexible thinking. IAC is a manual-guided therapy focused exclusively on substance use and recovery with modules organized in a stage-based approach: treatment initiation, early abstinence, maintaining abstinence and recovery. SC are intensive out-patient program services that include 9-12 hours of face-to-face contact per week over 2-4 days of group and individual therapies plus medication management. Primary outcomes were PTSD severity and substance use severity at 6 months. Secondary outcomes were therapy retention. PTSD symptoms reduced in all conditions with no difference between them. In analyses of covariance, ICBT produced more favorable outcomes on toxicology than IAC or SC [comparison with IAC, parameter estimate: 1.10; confidence interval (CI) = 0.17-2.04; comparison with SC, parameter estimate: 1.13; CI = 0.18-2.08] and had a greater reduction in reported drug use than SC (parameter estimate: -9.92; CI = -18.14 to -1.70). ICBT patients had better therapy continuation versus IAC (P<0.001). There were no unexpected or study-related adverse events. Integrated cognitive behavioral therapy may improve drug-related outcomes in post-traumatic stress disorder sufferers with substance use disorder more than drug-focused counseling, but probably not by reducing post-traumatic stress disorder symptoms to a greater extent. © 2015 Society for the Study of Addiction.
Students' perceptions of a community-based service-learning project related to aging in place.
Oakes, Claudia E; Sheehan, Nancy W
2014-01-01
This article describes a service-learning project that was designed to help undergraduate health professions students understand the complexities related to aging in place. The service-learning project also incorporated a research component to expose the students to the research process. Students' reflections regarding the benefits that they derived from the experience suggest that they value learning about older adults through one-on-one interactions more than they value the opportunity to participate in the research project. Implications for undergraduate health professional education are discussed.
Reflections on the prairie as a creative teaching-learning place.
Bunkers, Sandra Schmidt
2006-01-01
In this column, the author reflects on characteristics of the prairie land of South Dakota and how it contributes to a creative teaching-learning place. Attributes of the prairie that are linked with creative teaching-learning include prairie as a space of aloneness and solitude, prairie as a boundless seeing what may be, prairie as contradiction and paradox, and prairie as possibility. These attributes of the prairie are explored through the author's personal experience, theoretical literature on creativity and teaching-learning, and literature from Parse's theory of human becoming.
The role of sleep and sleep deprivation in consolidating fear memories.

Sleep, in particular REM sleep, has been shown to improve the consolidation of emotional memories. Here, we investigated the role of sleep and sleep deprivation on the consolidation of fear memories and underlying neuronal mechanisms. We employed a Pavlovian fear conditioning paradigm either followed by a night of polysomnographically monitored sleep, or wakefulness in forty healthy participants. Recall of learned fear was better after sleep, as indicated by stronger explicitly perceived anxiety and autonomous nervous responses. These effects were positively correlated with the preceding time spent in REM sleep and paralleled by activation of the basolateral amygdala. These findings suggest REM sleep-associated consolidation of fear memory in the human amygdala. In view of the critical participation of fear learning mechanisms in the etiology of anxiety and post-traumatic stress disorder, deprivation of REM sleep after exposure to distressing events is an interesting target for further investigation.

The multicontext approach addresses strategy use and self-monitoring skills within activities and contexts that are systematically varied to facilitate transfer of learning. This article illustrates the application of the multicontext approach by presenting a case study of an adult who is 5 years post-traumatic brain injury with executive dysfunction and limited awareness. A single case study design with repeated pre-post measures was used. Methods to monitor strategy generation and specific awareness within intervention are described. Findings suggest improved functional performance and generalization of use of an external strategy despite absence of changes in general self-awareness of deficits. This case describes the multicontext intervention process and provides clinical suggestions for working with individuals with serious deficits in awareness and executive dysfunction following traumatic brain injury.

The authors examined the effectiveness of virtual reality exposure augmented with D-cycloserine or alprazolam, compared with placebo, in reducing posttraumatic stress disorder (PTSD) due to military trauma. After an introductory session, five sessions of virtual reality exposure were augmented with D-cycloserine (50 mg) or alprazolam (0.25 mg) in a double-blind, placebo-controlled randomized clinical trial for 156 Iraq and Afghanistan war veterans with PTSD. PTSD symptoms significantly improved from pre- to posttreatment across all conditions and were maintained at 3, 6, and 12 months. There were no overall differences in symptoms between D-cycloserine and placebo at any time. Alprazolam and placebo differed significantly on the Clinician-Administered PTSD Scale score at posttreatment and PTSD diagnosis at 3 months posttreatment; the alprazolam group showed a higher rate of PTSD (82.8%) than the placebo group (47.8%). Between-session extinction learning was a treatment-specific enhancer of outcome for the D-cycloserine group only. At posttreatment, the D-cycloserine group had the lowest cortisol reactivity and smallest startle response during virtual reality scenes. A six-session virtual reality treatment was associated with reduction in PTSD diagnoses and symptoms in Iraq and Afghanistan veterans, although there was no control condition for the virtual reality exposure. There was no advantage of D-cycloserine for PTSD symptoms in primary analyses. In secondary analyses, alprazolam impaired recovery and D-cycloserine enhanced virtual reality outcome in patients who demonstrated within-session learning. D-cycloserine augmentation reduced cortisol and startle reactivity more than did alprazolam or placebo, findings that are consistent with those in the animal literature.

Individuals with mild traumatic brain injury (TBI) show diminished metabolic activity when studied with positron emission tomography (PET) with (18)F-fluorodeoxyglucose (FDG). Since blast injury may not be localized in the same specific anatomical areas in every patient or may be diffuse, significance probability mapping may be vulnerable to false-negative detection of abnormalities. To address this problem, we used an anatomically independent measure to assess PET scans: increased numbers of contiguous voxels that are 2 standard deviations below values found in an uninjured control group. We examined this in three age-matched groups of male patients: 16 veterans with a history of mild TBI, 17 veterans with both mild TBI and post-traumatic stress disorder (PTSD), and 15 veterans without either condition. After FDG administration, subjects performed a modified version of the California Verbal Learning Task. Clusters of low uptake voxels were identified by computing the mean and standard deviation for each voxel in the healthy combat veteran group and then determining the voxel-based z-score for the patient groups. Abnormal clusters were defined as those that contained contiguous voxels with a z-score <-2. Patients with mild TBI alone and patients with TBI+PTSD had larger clusters of low uptake voxels, and cluster size significantly differentiated the mild TBI groups from combat controls. Clusters were more irregular in shape in patients, and patients also had a larger number of low-activity voxels throughout the brain. In mild TBI and TBI+PTSD patients, but not healthy subjects, cluster volume was significantly correlated with verbal learning during FDG uptake.

Background: A clinical characteristic of posttraumatic stress disorder (PTSD) is persistently elevated fear responses to stimuli associated with the traumatic event. The objective herein is to determine whether extinction of fear responses is impaired in PTSD and whether such impairment is related to dysfunctional activation of brain regions known to be involved in fear extinction, viz., amygdala, hippocampus, ventromedial prefrontal cortex (vmPFC), and dorsal anterior cingulate cortex (dACC). Methods: Sixteen individuals diagnosed with PTSD and 15 trauma-exposed non-PTSD controls (TENCs) underwent a two-day fear conditioning and extinction protocol in a 3T fMRI scanner. Conditioning and extinction training were conducted on day 1. Extinction recall (or extinction memory) test was conducted on day 2 (extinguished conditioned stimuli presented in the absence of shock). Skin conductance response (SCR) was scored throughout the experiment as an index of the conditioned response. Results: SCR data revealed no significant differences between groups during acquisition and extinction of conditioned fear on day 1. On day 2, however, PTSD subjects showed impaired recall of extinction memory. Analysis of fMRI data showed greater amygdala activation in the PTSD group during day 1 extinction learning. During extinction recall, lesser activation in hippocampus and vmPFC, and greater activation in dACC, was observed in the PTSD group. The magnitude of extinction memory across all subjects was correlated with activation of hippocampus and vmPFC during extinction recall testing. Conclusions: These findings support the hypothesis that fear extinction is impaired in PTSD. They further suggest that dysfunctional activation in brain structures that mediate fear extinction learning, and especially its recall, underlie this impairment. PMID:19748076

Fear conditioning is an established model for investigating posttraumatic stress disorder (PTSD). However, symptom triggers may vaguely resemble the initial traumatic event, differing on a variety of sensory and affective dimensions. We extended the fear-conditioning model to assess generalization of conditioned fear on fear processing neurocircuitry in PTSD. Military veterans (n=67) consisting of PTSD (n=32) and trauma-exposed comparison (n=35) groups underwent functional magnetic resonance imaging during fear conditioning to a low fear-expressing face while a neutral face was explicitly unreinforced. Stimuli that varied along a neutral-to-fearful continuum were presented before conditioning to assess baseline responses, and after conditioning to assess experience-dependent changes in neural activity. Compared with trauma-exposed controls, PTSD patients exhibited greater post-study memory distortion of the fear-conditioned stimulus toward the stimulus expressing the highest fear intensity. PTSD patients exhibited biased neural activation toward high-intensity stimuli in fusiform gyrus (P<0.02), insula (P<0.001), primary visual cortex (P<0.05), locus coeruleus (P<0.04), thalamus (P<0.01), and at the trend level in inferior frontal gyrus (P=0.07). All regions except fusiform were moderated by childhood trauma. Amygdala–calcarine (P=0.01) and amygdala–thalamus (P=0.06) functional connectivity selectively increased in PTSD patients for high-intensity stimuli after conditioning. In contrast, amygdala–ventromedial prefrontal cortex (P=0.04) connectivity selectively increased in trauma-exposed controls compared with PTSD patients for low-intensity stimuli after conditioning, representing safety learning. In summary, fear generalization in PTSD is biased toward stimuli with higher emotional intensity than the original conditioned-fear stimulus. Functional brain differences provide a putative neurobiological model for fear generalization whereby PTSD symptoms are triggered by threat cues that merely resemble the index trauma. PMID:26670285

Entering college with posttraumatic stress disorder (PTSD) symptomatology has been linked to poor academic performance and increased risk for dropping out of college; however, little is known regarding the mechanisms by which PTSD symptoms have deleterious effects on college outcomes. Drawing from a self-regulated learning (SRL) perspective, which suggests that students' learning behaviors and outcomes can be influenced by contextual and developmental factors, we hypothesized that students who enter college with high PTSD symptomatology may experience difficulties in effort regulation, which in turn, may have deleterious effects on their academic performance and college persistence. These hypothesized relationships, as well as the potential gender differences in these relationships were examined using a longitudinal study design and a multigroup structural equation modeling approach. Of the 928 1st-year students who participated in the study, 484 (52.2%) students who reported lifetime exposure to traumatic events constituted the final sample of the study. The prevalence of PTSD among the trauma-exposed participants was 12.4%. After controlling for participation in on-campus activities and American College Testing (ACT) assessment scores, the relationship between PTSD symptomatology in the 1st semester of college and 2nd-year enrollment was mediated by effort regulation and 1st-year cumulative grade-point average (GPA). Specifically, participants who started college with higher levels of PTSD symptomatology also reported lower levels of effort regulation, which in turn, had a significant indirect effect on 2nd-year enrollment through 1st-year GPA. Results also indicated that the paths in the hypothesized model were not significantly different for men and women. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Exposure to traumatic events can increase the risk for major depressive disorder (MDD) as well as posttraumatic stress disorder (PTSD), and pharmacological treatments for these disorders often involve the modulation of serotonergic (5-HT) systems. Several behavioral paradigms in rodents produce changes in behavior that resemble symptoms of MDD and these behavioral changes are sensitive to antidepressant treatments. Here we review two animal models in which MDD-like behavioral changes are elicited by exposure to an acute traumatic event during adulthood, learned helplessness (LH) and conditioned defeat. In LH, exposure of rats to inescapable, but not escapable, tailshock produces a constellation of behavioral changes that include deficits in fight/flight responding and enhanced anxiety-like behavior. In conditioned defeat, exposure of Syrian hamsters to a social defeat by a more aggressive animal leads to a loss of territorial aggression and an increase in submissive and defensive behaviors in subsequent encounters with non-aggressive conspecifics. Investigations into the neural substrates that control LH and conditioned defeat revealed that increased 5-HT activity in the dorsal raphe nucleus (DRN) is critical for both models. Other key brain regions that regulate the acquisition and/or expression of behavior in these two paradigms include the basolateral amygdala (BLA), central nucleus of the amygdala (CeA) and bed nucleus of the stria terminalis (BNST). In this review, we compare and contrast the role of each of these neural structures in mediating LH and conditioned defeat, and discuss the relevance of these data in developing a better understanding of the mechanisms underlying trauma-related depression.

To evaluate the cooccurrence, and predictors of remission, of general anxiety, depression, and posttraumatic stress disorder symptoms during 2-year follow-up in survivors of acute lung injury treated in an ICU. Prospective cohort study, with follow-up at 3, 6, 12, and 24 months post-acute lung injury. Thirteen medical and surgical ICUs in four hospitals. Survivors among 520 patients with acute lung injury. The outcomes of interest were measured using the Hospital Anxiety and Depression Scale anxiety and depression subscales (scores ≥ 8 indicating substantial symptoms) and the Impact of Event Scale-Revised (scores ≥ 1.6 indicating substantial posttraumatic stress disorder symptoms). Of the 520 enrolled patients, 274 died before 3-month follow-up; 186 of 196 consenting survivors (95%) completed at least one Hospital Anxiety and Depression Scale and Impact of Event Scale-Revised assessment during 2-year follow-up, and most completed multiple assessments. Across follow-up time points, the prevalence of suprathreshold general anxiety, depression, and posttraumatic stress disorder symptoms ranged from 38% to 44%, 26% to 33%, and 22% to 24%, respectively; more than half of the patients had suprathreshold symptoms in at least one domain during 2-year follow-up. The majority of survivors (59%) with any suprathreshold symptoms were above threshold for two or more types of symptoms (i.e., general anxiety, depression, and/or posttraumatic stress disorder). In fact, the most common pattern involved simultaneous general anxiety, depression, and posttraumatic stress disorder symptoms. Most patients with general anxiety, depression, or posttraumatic stress disorder symptoms during 2-year follow-up had suprathreshold symptoms at 24-month (last) follow-up. Higher Short-Form-36 physical functioning domain scores at the prior visit were associated with a greater likelihood of remission from general anxiety and posttraumatic stress disorder symptoms during follow-up. The majority of acute lung injury survivors had clinically significant general anxiety, depression, or posttraumatic stress disorder symptoms, and these symptoms tended to co-occur across domains. Better physical functioning during recovery predicted subsequent remission of general anxiety and posttraumatic stress disorder symptoms.

Posttraumatic migraines are common after mild traumatic brain injury. The purpose of this study was to determine if a specific axonal injury pattern underlies posttraumatic migraines after mild traumatic brain injury utilizing Tract-Based Spatial Statistics analysis of diffusion tensor imaging. DTI was performed in 58 patients with mild traumatic brain injury with posttraumatic migraines. Controls consisted of 17 patients with mild traumatic brain injury without posttraumatic migraines. Fractional anisotropy and diffusivity maps were generated to measure white matter integrity and were evaluated by using Tract-Based Spatial Statistics regression analysis with a general linear model. DTI findings were correlated with symptom severity, neurocognitive test scores, and time to recovery with the Pearson correlation coefficient. Patients with mild traumatic brain injury with posttraumatic migraines were not significantly different from controls in terms of age, sex, type of injury, or neurocognitive test performance. Patients with posttraumatic migraines had higher initial symptom severity ( P = .01) than controls. Compared with controls, patients with mild traumatic brain injury with posttraumatic migraines had decreased fractional anisotropy in the corpus callosum ( P = .03) and fornix/septohippocampal circuit ( P = .045). Injury to the fornix/septohippocampal circuit correlated with decreased visual memory ( r = 0.325, P = .01). Injury to corpus callosum trended toward inverse correlation with recovery ( r = -0.260, P = .05). Injuries to the corpus callosum and fornix/septohippocampal circuit were seen in patients with mild traumatic brain injury with posttraumatic migraines, with injuries in the fornix/septohippocampal circuit correlating with decreased performance on neurocognitive testing. © 2017 by American Journal of Neuroradiology.
Acute and chronic efficacy of Bumetanide in an in vitro model of post-traumatic epileptogenesis
Dzhala, Volodymyr; Staley, Kevin
2014-01-01
Background Seizures triggered by acute injuries to the developing brain respond poorly to first-line medications that target the inhibitory chloride-permeable GABAA-receptor. Neuronal injury is associated with profound increases in cytoplasmic chloride ([Cl−]i) resulting in depolarizing GABA signaling, higher seizure propensity and limited efficacy of GABAergic anticonvulsants. The Na+-K+-2Cl− (NKCC1) co-transporter blocker bumetanide reduces [Cl−]i and causes more negative GABA equilibrium potential in injured neurons. We therefore tested both the acute and chronic efficacy of bumetanide on early post-traumatic ictal-like epileptiform discharges and epileptogenesis. Methods Acute hippocampal slices were used as a model of severe traumatic brain injury and post-traumatic epileptogenesis. Hippocampal slices were then incubated for three weeks. After a one week latent period slice cultures developed chronic spontaneous ictal-like discharges. The anticonvulsant and antiepileptogenic efficacy of bumetanide, phenobarbital and the combination of these drugs was studied. Results Bumetanide reduced the frequency and power of early post-traumatic ictal-like discharges in vitro and enhanced the anticonvulsant efficacy of phenobarbital. Continuous two-three week administration of bumetanide as well as phenobarbital in combination with bumetanide failed to prevent post-traumatic ictal-like discharges and epileptogenesis. Conclusions Our data demonstrate a persistent contribution of NKCC1 co-transport in post-traumatic ictal-like activity, presumably as a consequence of chronic alterations in neuronal chloride homeostasis and GABA-mediated inhibition. New strategies for more effective reduction in post-traumatic and seizure-induced [Cl−]i accumulation could provide the basis for effective treatments for post-traumatic epileptogenesis and the resultant seizures.

After traumatic events, social support and posttraumatic stress are interrelated, but little is known about the underlying dynamics behind this association. Levels of social support and posttraumatic stress may change and affect each other over time, but there are also stable time-invariant individual differences in both constructs. The present study aimed to determine the amount of variance explained by stable individual differences in levels of social support and posttraumatic stress across three years, and to determine whether and to what extent social support and posttraumatic stress may affect one another when these stable individual differences are controlled for. We used data from ministerial employees present in the Governmental district during the 2011 Oslo bombing attack (N=255). Data was collected ten months, two years, and three years after the terror attack. Using a random intercept cross lagged panel model (RI-CLPM), we tested the possible directional effects between social support and posttraumatic stress within persons when variance between persons was taken into account. The intraclass correlations of the three measures of posttraumatic stress and social support were.83 and.74, respectively. The remaining variation within persons could not be explained by change in either of these constructs. We have no information on the processes that might have occurred before 10 months after the incident. Our findings indicate that the long-term longitudinal linkage between social support and posttraumatic stress may be best explained by stable individual differences rather than causal processes operating within persons.

Post-traumatic stress disorder is pervasive in low- and middle-income countries. There is evidence to suggest that post-traumatic stress disorder is more common among people living with HIV than non-infected matched controls. We carried out a systematic review of interventions for adult post-traumatic stress disorder from resource poor settings with a focus on people living with HIV. We included all studies that investigated interventions for adult post-traumatic stress disorder from resource poor settings with a focus on interventions that were either randomised controlled trials or observational cohort studies carried out from 1980 to May 2015. Of the 25 articles that were identified for full review, two independent reviewers identified seven studies that met our study inclusion criteria. All randomised controlled trials (RCT) (n = 6) used cognitive behavioural therapy-based interventions and focused on people living with HIV in resource poor settings. There was only one study focusing on the use of lay counsellors to address post-traumatic stress disorder but core competencies were not described. There were no intervention studies from Africa, only an observational cohort study from Rwanda. Rigorously evaluated interventions for adult post-traumatic stress disorder in people living with HIV are rare. Most were undertaken in resource poor settings located in high-income countries. There is a need for research on the development and implementation of appropriate interventions for post-traumatic stress disorder in people living with HIV in low- and middle-income countries. © 2016 John Wiley & Sons Ltd.

This paper outlines the main infrastructure for implicating mobile learning in medicine and present a sample mobile learning application for medical learning within the framework of mobile learning systems. Mobile technology is developing nowadays. In this case it will be useful to develop different learning environments using these innovations in internet based distance education. M-learning makes the most of being on location, providing immediate access, being connected, and acknowledges learning that occurs beyond formal learning settings, in places such as the workplace, home, and outdoors. Central to m-learning is the principle that it is the learner who is mobile rather than the device used to deliver m learning. The integration of mobile technologies into training has made learning more accessible and portable. Mobile technologies make it possible for a learner to have access to a computer and subsequently learning material and activities; at any time and in any place. Mobile devices can include: mobile phone, personal digital assistants (PDAs), personal digital media players (eg iPods, MP3 players), portable digital media players, portable digital multimedia players. Mobile learning (m-learning) is particularly important in medical education, and the major users of mobile devices are in the field of medicine. The contexts and environment in which learning occurs necessitates m-learning. Medical students are placed in hospital/clinical settings very early in training and require access to course information and to record and reflect on their experiences while on the move. As a result of this paper, this paper strives to compare and contrast mobile learning with normal learning in medicine from various perspectives and give insights and advises into the essential characteristics of both for sustaining medical education.

Medial entorhinal grid cells and hippocampal place cells provide neural correlates of spatial representation in the brain. A place cell typically fires whenever an animal is present in one or more spatial regions, or places, of an environment. A grid cell typically fires in multiple spatial regions that form a regular hexagonal grid structure extending throughout the environment. Different grid and place cells prefer spatially offset regions, with their firing fields increasing in size along the dorsoventral axes of the medial entorhinal cortex and hippocampus. The spacing between neighboring fields for a grid cell also increases along the dorsoventral axis. This article presents a neural model whose spiking neurons operate in a hierarchy of self-organizing maps, each obeying the same laws. This spiking GridPlaceMap model simulates how grid cells and place cells may develop. It responds to realistic rat navigational trajectories by learning grid cells with hexagonal grid firing fields of multiple spatial scales and place cells with one or more firing fields that match neurophysiological data about these cells and their development in juvenile rats. The place cells represent much larger spaces than the grid cells, which enable them to support navigational behaviors. Both self-organizing maps amplify and learn to categorize the most frequent and energetic co-occurrences of their inputs. The current results build upon a previous rate-based model of grid and place cell learning, and thus illustrate a general method for converting rate-based adaptive neural models, without the loss of any of their analog properties, into models whose cells obey spiking dynamics. New properties of the spiking GridPlaceMap model include the appearance of theta band modulation. The spiking model also opens a path for implementation in brain-emulating nanochips comprised of networks of noisy spiking neurons with multiple-level adaptive weights for controlling autonomous adaptive robots capable of spatial navigation.

The dual-representation model of posttraumatic stress disorder (PTSD; Brewin, Gregory, Lipton, & Burgess, Psychological Review, 117, 210-232 2010) argues that intrusions occur when people fail to construct context-based representations during adverse experiences. The present study tested a specific prediction flowing from this model. In particular, we investigated whether the efficiency of temporal-lobe-based spatial configuration learning would account for individual differences in intrusive experiences and physiological reactivity in the laboratory. Participants (N = 82) completed the contextual cuing paradigm, which assesses spatial configuration learning that is believed to depend on associative encoding in the parahippocampus. They were then shown a trauma film. Afterward, startle responses were quantified during presentation of trauma reminder pictures versus unrelated neutral and emotional pictures. PTSD symptoms were recorded in the week following participation. Better configuration learning performance was associated with fewer perceptual intrusions, r = -.33, p < .01, but was unrelated to physiological responses to trauma reminder images (ps > .46) and had no direct effect on intrusion-related distress and overall PTSD symptoms, rs > -.12, ps > .29. However, configuration learning performance tended to be associated with reduced physiological responses to unrelated negative images, r = -.20, p = .07. Thus, while spatial configuration learning appears to be unrelated to affective responding to trauma reminders, our overall findings support the idea that the context-based memory system helps to reduce intrusions.

This study evaluated the factors associated with post-traumatic stress symptoms in Korean adolescents who lived in a disaster-affected community. A total of 1101 students attending secondary and high schools in Jindo, the location of the Sewol ferry disaster, were enrolled in a cross-sectional survey. The Child Report of Post-traumatic Symptoms (CROPS), the Center for Epidemiological Studies Depression Scale (CES-D), and the State Anxiety Inventory for Children (SAIC) were administered. Female gender, older children, poor academic achievement, and directly witnessing the rescue scene were associated with post-traumatic stress symptoms. The CES-D and SAIC scores of subjects with witness of the rescue were significantly higher than those of respondents without such experiences. The regression analysis revealed that directly witnessing the rescue scene was significantly associated with post-traumatic stress symptoms after adjusting for other variables. The results of this study suggest that witnessing the rescue scene following a disaster might be a risk factor for post-traumatic stress symptoms in adolescents in disaster-affected communities.

We evaluated whether traumatic events are associated with a distinctive pattern of socio-demographic and clinical features of obsessive-compulsive disorder (OCD). We compared socio-demographic and clinical features of 106 patients developing OCD after post-traumatic stress disorder (PTSD; termed post-traumatic OCD), 41 patients developing OCD before PTSD (pre-traumatic OCD), and 810 OCD patients without any history of PTSD (non-traumatic OCD) using multinomial logistic regression analysis. A later age at onset of OCD, self-mutilation disorder, history of suicide plans, panic disorder with agoraphobia, and compulsive buying disorder were independently related to post-traumatic OCD. In contrast, earlier age at OCD onset, alcohol-related disorders, contamination-washing symptoms, and self-mutilation disorder were all independently associated with pre-traumatic OCD. In addition, patients with post-traumatic OCD without a previous history of obsessive-compulsive symptoms (OCS) showed lower educational levels, greater rates of contamination-washing symptoms, and more severe miscellaneous symptoms as compared to post-traumatic OCD patients with a history of OCS.

Post-traumatic hepatic pseudoaneurysms are rare. We report a very unusual case of bile duct injury complicated with an asymptomatic post-traumatic hepatic pseudoaneurysm. A previously healthy 17-year-old man sustained multiple traumas after a motorcycle accident. Post-traumatic hepatic pseudoaneurysms were detected after blunt liver injury. The rapid growth of the pseudoaneurysms in the hepatic hilus compressed the common hepatic bile duct and caused extrahepatic bile leakage at the lateral lobe. At first, the hepatic arterial pseudoaneurysms were embolized and bile leakage at the left lobe was treated conservatively. Finally, however, segment 2 and 3 partial liver resection should have been performed to stop the bile leakage. Post-traumatic pseudoaneurysm should be ruled out, in addition to the presence of biliary tract injury, if the intraperitoneal bile leakage appears after liver injury.

To investigate the responses of middle and high school students exposed to the 1995 Oklahoma City bombing across a spectrum of loss. A questionnaire measuring exposure, personal consequences, initial response, and current posttraumatic stress and other symptoms was administered to 3,218 students 7 weeks after the explosion. More than one third of the sample knew someone killed in the explosion. Bereaved youths were more likely than nonbereaved peers to report immediate symptoms of arousal and fear, changes in their home and school environment, and posttraumatic stress symptoms. Retrospective measures of initial arousal and fear predicted posttraumatic stress symptoms at 7 weeks. The results support the literature addressing the role of initial response in posttraumatic stress symptom development. The study raises concern about the impact of television, and traumatized youths' reactivity to it, in the aftermath of disaster.
Confirmatory factor analysis of posttraumatic stress symptoms in sexually harassed women.

2005-12-01
Posttraumatic stress disorder (PTSD) factor analytic research to date has not provided a clear consensus on the structure of posttraumatic stress symptoms. Seven hypothesized factor structures were evaluated using confirmatory factor analysis of the Posttraumatic Stress Disorder Checklist, a paper-and-pencil measure of posttraumatic stress symptom severity, in a sample of 1,218 women who experienced a broad range of workplace sexual harassment. The model specifying correlated re-experiencing, effortful avoidance, emotional numbing, and hyperarousal factors provided the best fit to the data. Virtually no support was obtained for the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV; American Psychiatric Association, 1994) three-factor model of re-experiencing, avoidance, and hyperarousal factors. Different patterns of correlations with external variables were found for the avoidance and emotional numbing factors, providing further validation of the supported model.

Childhood sexual abuse can be extremely traumatic and lead to lifelong symptomatology. The present study examined the impact of several demographic, abuse, and psychosocial variables on posttraumatic stress disorder severity among a consecutive sample of treatment-seeking, adult child sexual abuse survivors (N = 480). The child sexual abuse sample was characterized by severe trauma exposure, insecure attachment, and significant traumatization, with an estimated 77% suffering from posttraumatic stress disorder, more than twice the level of the comparison group. Regression analyses revealed risk factors associated with the development of posttraumatic stress disorder in which the strongest predictors being additional traumas, negative affectivity, and somatization. The findings add to existing research confirming the stressful nature of child sexual abuse and the variables that contribute to the development and severity of posttraumatic stress disorder.

Purpose To examine the potential effects of eye movement desensitization and reprocessing (EMDR) in children with epilepsy-related posttraumatic stress and/or anxiety symptoms, using a case series design. Methods Five children (aged 8–18) with epilepsy identified for seizure-related posttraumatic stress and/or anxiety symptoms were treated with EMDR. To examine potential treatment effects, posttraumatic stress and anxiety symptoms were assessed (CRTI and SCARED) pre- and post-EMDR and at 3-month follow-up. Normative deviation scores were calculated to examine the severity of seizure-related posttraumatic stress and anxiety symptoms over time. The reliable change index was calculated for pre- to posttreatment change of seizure-related posttraumatic stress and/or anxiety symptoms. Results Before EMDR, overall or subscale scores indicated that all children had (sub)clinical seizure-related posttraumatic stress symptoms and/or anxiety symptoms. Directly after EMDR, most children showed significant and/or clinical individual improvement, and these beneficial effects were maintained or reached at follow-up. The mean number of sessions was 2 (range 1–3, 45 min per session). Conclusions In case of seizure-related posttraumatic stress and/or anxiety, this study indicates that EMDR is a potentially successful quick and safe psychological treatment for children with epilepsy. Highlights of the article The first study to examine the potential effects of EMDR to reduce clinical seizure-related posttraumatic stress symptoms and/or anxiety symptoms in children with epilepsy. After 1–3 EMDR (45 min) sessions, positive treatment effects were found on a range of seizure-related PTSD symptoms and/or anxiety symptoms. During treatment, no seizures, absences, or any other adverse events were observed; the seizure diaries showed that none of the children experienced more seizures (or an unusual pattern) after treatment. At the reevaluation of EMDR, all children and parents reported improvement in physical, emotional, cognitive, or social functioning. PMID:27387846

Maximizing Exposure Therapy: An Inhibitory Learning Approach
Craske, Michelle G.; Treanor, Michael; Conway, Chris; Zbozinek, Tomislav; Vervliet, Bram
2014-01-01
Exposure therapy is an effective approach for treating anxiety disorders, although a substantial number of individuals fail to benefit or experience a return of fear after treatment. Research suggests that anxious individuals show deficits in the mechanisms believed to underlie exposure therapy, such as inhibitory learning. Targeting these processes may help improve the efficacy of exposure-based procedures. Although evidence supports an inhibitory learning model of extinction, there has been little discussion of how to implement this model in clinical practice. The primary aim of this paper is to provide examples to clinicians for how to apply this model to optimize exposure therapy with anxious clients, in ways that distinguish it from a ‘fear habituation’ approach and ‘belief disconfirmation’ approach within standard cognitive-behavior therapy. Exposure optimization strategies include 1) expectancy violation, 2) deepened extinction, 3) occasional reinforced extinction, 4) removal of safety signals, 5) variability, 6) retrieval cues, 7) multiple contexts, and 8) affect labeling. Case studies illustrate methods of applying these techniques with a variety of anxiety disorders, including obsessive-compulsive disorder, posttraumatic stress disorder, social phobia, specific phobia, and panic disorder.

There has been a push towards the education of students with Learning Disabilities in inclusive educational settings with their non-disabled peers. Zigmond (2003) stated that it is not the placement of students with disabilities in general education setting alone that would guarantee their successes; instead, the strategies teachers use to ensure that these children are being engaged and learning will enable them become successful. Despite the fact that there are several bodies of research on effective teaching of students with learning disabilities, special education teachers continue to have difficulties concerning the appropriate strategies for promoting student engagement and improving learning for students with learning disabilities placed in inclusive educational settings (Zigmond, 2003). This qualitative study interviewed and collected data from fifteen high performing special education teachers who were employed in a Southern state elementary school district to uncover the strategies they have found useful in their attempts to promote student engagement and attempts to improve student achievement for students with learning disabilities placed in inclusive educational settings. The study uncovered strategies for promoting engagement and improving learning outcomes for students with learning disabilities placed in inclusive classrooms. The findings showed that in order to actually reach the students with learning disabilities, special education teachers must go the extra miles by building rapport with the school communities, possess good classroom management skills, and become student advocates.

Many Iraqi refugees suffer from posttraumatic stress. Efficient, culturally sensitive interventions are needed, and so we adapted narrative exposure therapy into a brief version (brief NET) and tested its effects in a sample of traumatized Iraqi refugees. Iraqi refugees in the United States reporting elevated posttraumatic stress (N = 63) were randomized to brief NET or waitlist control conditions in a 2:1 ratio; brief NET was 3 sessions, conducted individually, in Arabic. Positive indicators (posttraumatic growth and well-being) and symptoms (posttraumatic stress, depressive, and somatic) were assessed at baseline and 2- and 4-month follow-up. Treatment participation (95.1% completion) and study retention (98.4% provided follow-up data) were very high. Significant condition by time interactions showed that those receiving brief NET had greater posttraumatic growth (d = 0.83) and well-being (d = 0.54) through 4 months than controls. Brief NET reduced symptoms of posttraumatic stress (d = -0.48) and depression (d = -0.46) more, but only at 2 months; symptoms of controls also decreased from 2 to 4 months, eliminating condition differences at 4 months. Three sessions of brief NET increased growth and well-being and led to symptom reduction in highly traumatized Iraqi refugees. This preliminary study suggests that brief NET is both acceptable and potentially efficacious in traumatized Iraqi refugees. Copyright © 2014 International Society for Traumatic Stress Studies.

This study attempted to identify remembered reactions of Oklahoma City residents at the time of the April 1995 terrorist bombing that predicted later development of posttraumatic stress symptoms. Eighty-six adults who sought help for distress related to the bombing six months after it occurred completed a survey about demographic characteristics, level of exposure to the event, symptoms of grief, retrospective reports of reactions at the time of the trauma, current posttraumatic stress symptoms, and coping strategies. To identify immediate bombing reactions predictive of later distress, retrospective reports of reactions to the trauma were correlated with current posttraumatic stress symptoms. Multiple regression analysis was used to determine which reactions predicted the emergence of posttraumatic stress symptoms. Reactions of being nervous and being upset by how other people acted when the bombing occurred accounted for about one-third of the total variation in posttraumatic stress symptom scores and thus were major predictors of posttraumatic stress. These results differ from those of other studies in which peritraumatic dissociation, or dissociation at the time of the event, was more predictive than anxiety for developing later distress. The results suggest that persons who experience significant anxiety at the time of the traumatic event may continue to experience distress. Those who are overly concerned about others' actions may be showing diminished interpersonal trust, evidence of terrorism's ability to erode social harmony.

The psychological effects of community violence exposure among inner-city youth are severe, yet little is known about its prevalence and moderators among suburban middle-class youth. This study aimed to assess the prevalence of community violence exposure among suburban American youth, to examine associated posttraumatic stress and to evaluate factors related to severe vs. less severe posttraumatic stress, such as co-existing internalizing and externalizing problems, as well as the effects of teacher support, parental warmth and support, perceived neighborhood safety and conventional involvement in this context. Data were collected from 780 suburban, predominantly Caucasian middle-class high-school adolescents in the Northeastern US during the Social and Health Assessment (SAHA) study. A substantial number of suburban youth were exposed to community violence and 24% of those victimized by community violence developed severe posttraumatic stress. Depressive symptoms were strongly associated with higher levels and perceived teacher support with lower levels of posttraumatic stress. Similar to urban youth, youth living in suburban areas in North American settings may be affected by community violence. A substantial proportion of these youth reports severe posttraumatic stress and high levels of comorbid depressive symptoms. Teacher support may have a protective effect against severe posttraumatic stress and thus needs to be further assessed as a potential factor that can be used to mitigate the detrimental effects of violence exposure.

The high comorbidity rates of posttraumatic stress disorder and chronic pain have been widely reported, but the underlying mechanisms remain unclear. Emerging evidence suggested that an excess of inflammatory immune activities in the hippocampus involved in the progression of both posttraumatic stress disorder and chronic pain. Considering that microglia are substrates underlying the initiation and propagation of the neuroimmune response, we hypothesized that stress-induced activation of hippocampal microglia may contribute to the pathogenesis of posttraumatic stress disorder-pain comorbidity. We showed that rats exposed to single prolonged stress, an established posttraumatic stress disorder model, exhibited persistent mechanical allodynia and anxiety-like behavior, which were accompanied by increased activation of microglia and secretion of pro-inflammatory cytokines in the hippocampus. Correlation analyses showed that hippocampal activation of microglia was significantly correlated with mechanical allodynia and anxiety-like behavior. Our data also showed that both intraperitoneal and intra-hippocampal injection of minocycline suppressed single prolonged stress-induced microglia activation and inflammatory cytokines accumulation in the hippocampus, and attenuated both single prolonged stress-induced mechanical allodynia and anxiety-like behavior. Taken together, the present study suggests that stress-induced microglia activation in the hippocampus may serve as a critical mechanistic link in the comorbid relationship between posttraumatic stress disorder and chronic pain. The novel concept introduces the possibility of cotreating chronic pain and posttraumatic stress disorder. © The Author(s) 2016.

To examine the relationship between nurses' exposure to workplace bullying and Post-Traumatic Stress Disorder symptomology and the protective role of psychological capital (PsyCap). Workplace bullying has serious organisational and health effects in nursing. Few studies have examined the relation of workplace bullying to serious mental health outcomes, such as Post-Traumatic Stress Disorder. Even fewer have examined the effect of intrapersonal strengths on the health impact of workplace bullying. A survey of 1205 hospital nurses was conducted to test the hypothesized model. Nurses completed standardized measures of bullying, Post-Traumatic Stress Disorder and PsyCap. A moderated regression analysis revealed that more frequent exposure to workplace bullying was significantly related to Post-Traumatic Stress Disorder symptomology regardless of the PsyCap level. That is, PsyCap did not moderate the bullying/PTSD relationship in either group. Bullying exposure and PsyCap were significant independent predictors of Post-Traumatic Stress Disorder symptoms in both groups. Efficacy, a subdimension of PsyCap, moderated the bullying/Post-Traumatic Stress Disorder relationship only among experienced nurses. Workplace bullying appears to be predictive of Post-Traumatic Stress Disorder symptomology, a serious mental health outcome. Workplace bullying is a serious threat to nurses' health and calls for programmes that eliminate bullying and encourage greater levels of positive resources among nurses. © 2013 John Wiley & Sons Ltd.

Background Family history of psychiatric and substance use disorders has been associated with posttraumatic stress disorder (PTSD) in cross-sectional studies. Method Using a prospective design, we examined the relationships of family history of psychiatric and substance use disorders to posttraumatic stress symptoms in 278 healthy police recruits. During academy training, recruits were interviewed on family and personal psychopathology, prior cumulative civilian trauma exposure, and completed self-report questionnaires on nonspecific symptoms of distress and alcohol use. Twelve months after commencement of active duty, participants completed questionnaires on critical incident exposure over the previous year, peritraumatic distress to the worst critical incident during this time, and posttraumatic stress symptoms. Results A path model indicated: 1) family loading for mood and anxiety disorders had an indirect effect on posttraumatic stress symptoms at 12 months that was mediated through peritraumatic distress to the officer’s self-identified worst critical incident; 2) family loading for substance use disorders also predicted posttraumatic stress symptoms at 12 months and this relationship was mediated through peritraumatic distress. Conclusion These findings support a model in which family histories of psychopathology and substance abuse are pre-existing vulnerability factors for experiencing greater peritraumatic distress to critical incident exposure which, in turn, increases the risk for development of symptoms of posttraumatic stress disorder. Replication in other first responders, military and civilians will be important to determine generalizability of these findings. PMID:19683259

Individuals vary in how they respond to bereavement. Those who experience poor bereavement outcomes often report symptoms from more than one diagnostic category. This study sought to identify groups of individuals who share similar patterns of prolonged grief disorder and posttraumatic stress disorder symptoms to determine whether these profiles are differentially related to negative appraisals thought to contribute to prolonged grief disorder and posttraumatic stress disorder symptomatology. Participants were 185 bereaved adults. Latent class analysis was used to identify subgroups of individuals who showed similar patterns of co-occurrence of prolonged grief disorder and posttraumatic stress disorder symptoms. Multinomial regression was used to examine the extent to which appraisal domains and sociodemographic and loss factors predicted class membership. Latent class analysis revealed three classes of participants: a low symptom group, a high prolonged grief disorder symptom group, and a high prolonged grief disorder and posttraumatic stress disorder symptom group. Membership of the prolonged grief disorder group and prolonged grief disorder and posttraumatic stress disorder group was predicted by higher mean negative self-related appraisals. Demographic and loss-related factors did not predict group membership. These findings have implications for understanding co-occurrence of prolonged grief disorder and posttraumatic stress disorder symptoms following bereavement. Findings are consistent with theoretical models highlighting the importance of negative self-related beliefs in prolonged grief disorder.

Cognitive-behavioral models of posttraumatic stress disorder (PTSD) propose that the content of one's thoughts, including negative beliefs about the self, others, and world, play a fundamental role in our understanding and treatment of PTSD. Metacognitive theory suggests that metacognitive beliefs (i.e., beliefs about thinking), rather than content-specific beliefs, underlie PTSD. The present study provided the first known examination of the incremental contribution of metacognitive beliefs and trauma-related cognitions in relation to posttraumatic stress. Community adults recruited through an online crowdsourcing website who reported experiencing a criterion A traumatic event (N = 299) completed self-report measures of the study variables. Results from multiple linear regression analyses indicated that metacognitive beliefs of the uncontrollability and danger of thinking shared associations with each posttraumatic stress symptom cluster after accounting for the effects of content-specific beliefs and other covariates. The individual content-specific beliefs did not consistently share associations with posttraumatic stress symptoms in the regression analyses. The contribution of the individual content-specific beliefs to posttraumatic stress symptoms was consistently attenuated or rendered nonsignificant after accounting for metacognitive beliefs. These results are consistent with metacognitive theory in suggesting that metacognitive beliefs may be more important than trauma-related thought content in relation to posttraumatic stress.

Work-based non-formal learning plays a key role in faculty development yet these processes are yet to be described in detail in medical education. This study sets out to illuminate these processes so that potential benefits for new and inexperienced medical educators and their mentors can be realised. The non-formal learning processes of 12 novice teachers were investigated across hospital, general practice and medical school settings. The research sought to describe 'what' and 'how' non-formal learning takes place, and whether these processes differ across teaching sites. Both clinical and non-clinical teachers of medical undergraduates from one inner city medical school were recruited for the study. Through semi-structured interviews and a 'concept map', participants were asked to identify the people and tasks which they considered central to helping them become more expert as educators. Results identified non-formal learning across a number of key dimensions, including personal development, task and role performance, and optimising clinical teaching. This learning takes place as an outcome of experience, observation, reflection and student feedback. Non-formal learning is a significant aspect of the development of novice teachers and as such it needs to be placed more firmly upon the agenda of faculty development.

Science education through informal education

To develop the pedagogic efficiency of informal education in science teaching, promoting a close cooperation between institutions is suggested by Monteiro, Janerine, de Carvalho, and Martins. In their article, they point out effective examples of how teachers and educators work together to develop programs and activities at informal education places such as science museums. Their study explored and discussed the viability and relevancy of school visits to museums and possibilities to enhance the connection between students' visits in informal contexts and their learning in schools. Given that students learn science by crossing the boundaries of formal and informal learning contexts, it is critical to examine ways of integrated and collaborative approach to develop scientific literacy to help students think, act and communicate as members of problem solving communities. In this forum, we suggest the importance of students' lifeworld contexts in informal learning places as continuum of Monteiro, Janerine, de Carvalho, and Martins' discussion on enhancing the effectiveness of informal learning places in science education.

Patients affected by panic disorder with agoraphobia (PDA) often suffer from visuo-spatial disturbances. In the present study, we tested the place-learning abilities in a sample of 31 PDA patients compared to 31 healthy controls (CTR) using the computer-generated arena (C-G Arena), a desktop-based computer program developed at the University of Arizona (Jacobs et al 1997, for further detail about the program, see http://web.arizona.edu/~arg/data.html). Subjects were asked to search the computer-generated space, over several trials, for the location of a hidden target. Results showed that control subjects rapidly learned to locate the invisible target and consistently returned to it, while PDA patients were divided in two subgroups: some of them (PDA-A) were as good as controls in place learning, while some others (PDA-B) were unable to learn the correct strategies to find the target. Further analyses revealed that PDA-A patients were significantly younger and affected by panic disorder from less time than PDA-B, indicating that age and duration of illness can be critical factors that influence the place-learning abilities. The existence of two different subgroups of PDA patients who differ in their spatial orientation abilities could provide new insight into the mechanisms of panic and open new perspectives in the cognitive-behavioral treatment of this diffuse and disabling disorder.

The study investigated associations between workplace bullying and post-traumatic stress symptoms as compared to and controlled for associations between the latter and other psychosocial stress factors at work and in everyday life. The study employed a representative sample of Lithuanian family physicians, hence investigated a particularly resourceful occupational group in a geographical region earlier found to have a high risk context for exposure to bullying at work. With a response rate of 89.2%, a total of 323 family physicians filled in an anonymous questionnaire on workplace bullying, post-traumatic symptomatology (IES-R), other psychosocial stressors at work and in everyday life, personal health resources (sense of coherence), behavioral characteristics and demographic variables. The statistical software SPSS 14.0, Windows was used in the analysis. Associations were tested using a multivariate logistic regression analysis. A high prevalence of bullying was found among family physicians in Lithuania, with 13% of them experiencing severe workplace bullying and 17.3% experiencing more occasional incidents of bullying. The prevalence of post-traumatic stress symptoms was also high with 15.8% scoring above the standardized cut-off thresholds for post-traumatic stress disorder. The odds ratio (OR) of severe bullying for post-traumatic stress after adjustment for age and gender was 8.05 (95% confidence intervals (CI): 3.80-17.04). In the fully adjusted model it increased to 13.88 (95% CI: 4.68-41.13) indicating cumulative effects of all the investigated stressors. Workplace bullying is particularly prevalent among Lithuanian family physicians, as are the symptoms of post-traumatic distress. Strong associations between post-traumatic stress and exposure to severe bullying indicate that bullying is a significant source of mental health.

To evaluate the relative efficacies of trauma-focused cognitive behavior therapy and problem-solving therapy in treating post-traumatic stress disorder in children affected by civil conflict in Aceh, Indonesia. A controlled trial of children with post-traumatic stress disorder ( N = 64) randomized children to either five individual weekly sessions of trauma-focused cognitive behavior therapy or problem-solving therapy provided by lay-counselors who were provided with brief training. Children were assessed by blind independent assessors at pretreatment, posttreatment and 3-month follow-up on post-traumatic stress disorder, depression and anger, as well as caregiver ratings of the child's post-traumatic stress disorder levels. Intent-to-treat analyses indicated no significant linear time × treatment condition interaction effects for post-traumatic stress disorder at follow-up ( t(129.05) = -0.55, p = 0.58), indicating the two conditions did not differ. Across both conditions, there were significant reductions in post-traumatic stress disorder on self-reported ( t(131.26) = -9.26, p < 0.001) and caregiver-reported ( t(170.65) = 3.53, p = 0.001) measures and anger ( t(127.66) = -7.14, p < 0.001). Across both conditions, there was a large effect size for self-reported post-traumatic stress disorder (cognitive behavior therapy: 3.73, 95% confidence interval = [2.75, 3.97]; problem-solving: 2.68, 95% confidence interval = [2.07, 3.29]). These findings suggest that trauma-focused cognitive behavior therapy and problem-solving approaches are comparably successful in reducing post-traumatic stress disorder and anger in treating mental health in children in a post-conflict setting. This pattern may reflect the benefits of non-specific therapy effects or gains associated with trauma-focused or problem-solving approaches.

The present study investigated maternal emotion regulation as mediating the association between maternal posttraumatic stress symptoms and children's emotional dysregulation in a community sample of 431 Israeli mothers and children exposed to trauma. Little is known about the specific pathways through which maternal posttraumatic symptoms and deficits in emotion regulation contribute to emotional dysregulation. Inspired by the intergenerational process of relational posttraumatic stress disorder (PTSD), in which posttraumatic distress is transmitted from mothers to children, we suggest an analogous concept of relational emotion regulation, by which maternal emotion regulation problems may contribute to child emotion regulation deficits. Child emotion regulation problems were measured using the Child Behavior Checklist-Dysregulation Profile (CBCL-DP; T.M. Achenbach & I. Rescorla, 2000), which is comprised of three subscales of the CBCL: Attention, Aggression, and Anxiety/Depression. Maternal PTSD symptoms were assessed by the Posttraumatic Diagnostic Scale (E.B. Foa, L. Cashman, L. Jaycox, & K. Perry, 1997) and maternal emotion regulation by the Difficulties in Emotion Regulation Scale (K.L. Gratz & L. Roemer, 2004). Results showed that the child's emotion regulation problems were associated with both maternal posttraumatic symptoms and maternal emotion dysregulation. Further, maternal emotion regulation mediated the association between maternal posttraumatic symptoms and the child's regulation deficits. These findings highlight the central role of mothers' emotion regulation skills in the aftermath of trauma as it relates to children's emotion regulation skills. The degree of mothers' regulatory skills in the context of posttraumatic stress symptoms reflects a key process through which the intergenerational transmission of trauma may occur. Study results have critical implications for planning and developing clinical interventions geared toward the treatment of families in the aftermath of trauma and, in particular, the enhancement of mothers' emotion regulation skills after trauma. © 2015 Michigan Association for Infant Mental Health.

Objective To evaluate the effectiveness of cognitive therapy for post-traumatic stress disorder related to terrorism and other civil conflict in Northern Ireland. Design Randomised controlled trial. Setting Community treatment centre, Northern Ireland. Participants 58 consecutive patients with chronic post-traumatic stress disorder (median 5.2 years, range 3 months to 32 years) mostly resulting from multiple traumas linked to terrorism and other civil conflict. Interventions Immediate cognitive therapy compared with a waiting list control condition for 12 weeks followed by treatment. Treatment comprised a mean of 5.9 sessions during 12 weeks and 2.0 sessions thereafter. Main outcome measures Primary outcome measures were patients' scores for post-traumatic stress disorder (post-traumatic stress diagnostic scale) and depression (Beck depression inventory). The secondary outcome measure was scores for occupational and social functioning (work related disability, social disability, and family related disability) on the Sheehan disability scale. Results At 12 weeks after randomisation, immediate cognitive therapy was associated with significantly greater improvement than the waiting list control group in the symptoms of post-traumatic stress disorder (mean difference 9.6, 95% confidence interval 3.6 to 15.6), depression (mean difference 10.1, 4.8 to 15.3), and self reported occupational and social functioning (mean difference 1.3, 0.3 to 2.5). Effect sizes from before to after treatment were large: post-traumatic stress disorder 1.25, depression 1.05, and occupational and social functioning 1.17. No change was observed in the control group. Conclusion Cognitive therapy is an effective treatment for post-traumatic stress disorder related to terrorism and other civil conflict.

Large numbers of United States service members and veterans are enrolling in colleges and universities. Many are experiencing posttraumatic stress symptoms secondary to their military service, and these symptoms are associated with academic dysfunction. However, little is known about the mechanism(s) through which posttraumatic stress increases risk for academic difficulties. The goal of the current study was to evaluate perceived interpersonal relationship quality as a mediator of this association. The current study investigated the indirect effect of posttraumatic stress on academic dysfunction through three indices of perceived interpersonal relationship quality (i.e., family distress, family support, and social network support) in a clinical sample of 2,120 student service members and veterans. Participants were further divided into four groups based on relationship status and gender (i.e., partnered women, nonpartnered women, partnered men, and nonpartnered men), and moderation by group was examined. For all four groups, there were significant indirect effects of posttraumatic stress on academic dysfunction through greater family distress and lower social network support. Further, the overall indirect effect of posttraumatic stress on academic dysfunction was stronger for partnered women compared with the three other groups and was attributable to the stronger path from family distress to academic dysfunction for partnered women. Poor perceived relationship quality may be a modifiable risk factor for academic dysfunction among student service members and veterans experiencing military-related posttraumatic stress. Partnered women may be especially well-suited to interventions that enhance the interpersonal context of posttraumatic stress as a way to optimize academic outcomes.

Midwives frequently witness traumatic birth events. Little is known about responses to birth trauma and prevalence of posttraumatic stress among Australian midwives. To assess exposure to different types of birth trauma, peritraumatic reactions and prevalence of posttraumatic stress. Members of the Australian College of Midwives completed an online survey. A standardised measure assessed posttraumatic stress symptoms. More than two-thirds of midwives (67.2%) reported having witnessed a traumatic birth event that included interpersonal care-related trauma features. Midwives recalled strong emotions during or shortly after witnessing the traumatic birth event, such as feelings of horror (74.8%) and guilt (65.3%) about what happened to the woman. Midwives who witnessed birth trauma that included care-related features were significantly more likely to recall peritraumatic distress including feelings of horror (OR=3.89, 95% CI [2.71, 5.59]) and guilt (OR=1.90, 95% CI [1.36, 2.65]) than midwives who witnessed non-interpersonal birth trauma. 17% of midwives met criteria for probable posttraumatic stress disorder (95% CI [14.2, 20.0]). Witnessing abusive care was associated with more severe posttraumatic stress than other types of trauma. Witnessing care-related birth trauma was common. Midwives experience strong emotional reactions in response to witnessing birth trauma, in particular, care-related birth trauma. Almost one-fifth of midwives met criteria for probable posttraumatic stress disorder. Midwives carry a high psychological burden related to witnessing birth trauma. Posttraumatic stress should be acknowledged as an occupational stress for midwives. The incidence of traumatic birth events experienced by women and witnessed by midwives needs to be reduced.

Learning arises through the activity of large ensembles of cells, yet most of the data neuroscientists accumulate is at the level of individual neurons; we need models that can bridge this gap. We have taken spatial learning as our starting point, computationally modeling the activity of place cells using methods derived from algebraic topology, especially persistent homology. We previously showed that ensembles of hundreds of place cells could accurately encode topological information about different environments (“learn” the space) within certain values of place cell firing rate, place field size, and cell population; we called this parameter space the learning region. Here we advance the model both technically and conceptually. To make the model more physiological, we explored the effects of theta precession on spatial learning in our virtual ensembles. Theta precession, which is believed to influence learning and memory, did in fact enhance learning in our model, increasing both speed and the size of the learning region. Interestingly, theta precession also increased the number of spurious loops during simplicial complex formation. We next explored how downstream readout neurons might define co-firing by grouping together cells within different windows of time and thereby capturing different degrees of temporal overlap between spike trains. Our model's optimum coactivity window correlates well with experimental data, ranging from ∼150–200 msec. We further studied the relationship between learning time, window width, and theta precession. Our results validate our topological model for spatial learning and open new avenues for connecting data at the level of individual neurons to behavioral outcomes at the neuronal ensemble level. Finally, we analyzed the dynamics of simplicial complex formation and loop transience to propose that the simplicial complex provides a useful working description of the spatial learning process.
