Glycyrrhizin Treatment Facilitates Extinction of Conditioned Fear Responses After a Single Prolonged Stress Exposure in Rats.

Impaired fear memory extinction is widely considered a key mechanism of post-traumatic stress disorder (PTSD). Recent studies have suggested that neuroinflammation after a single prolonged stress (SPS) exposure may play a critical role in the impaired fear memory extinction. Studies have shown that high mobility group box chromosomal protein 1 (HMGB-1) is critically involved in neuroinflammation. However, the role of HMGB-1 underlying the development of impairment of fear memory extinction is still not know...


Mental disorders specifically associated with stress in the upcoming ICD-11: An overview.

The release of upcoming ICD-11 results in important changes to the classification of stress-related mental disorders. With the aim to improve clinical utility there is a new organizational structure for the different disorders as they are now categorized by the response to specific types of stressors. These range from reactions based on the experience of psychosocial strains (adjustment disorder), to grief reactions with a need for treatment (prolonged grief disorder) and reactions after exposure to traumat...

Role of dopamine D3 receptor in alleviating behavioural deficits in animal models of post-traumatic stress disorder.

Post-traumatic stress disorder (PTSD) is a complicated psychiatric disorder, which occurs after exposure to a traumatic event. The main clinical manifestation of PTSD includes fear and stress dysregulation. In both animals and humans, dysregulation of dopamine function appears to be related to conditioned fear responses. Previous studies show that the dopamine D3 receptor (D3R) is involved in schizophrenia, autism, and substance use disorders and is related to emotional disorders. However, few studies have ...


Anticipatory stress associated with functional magnetic resonance imaging: Implications for psychosocial stress research.

Stress tasks performed during functional magnetic resonance imaging (fMRI) elicit a relatively small cortisol response compared to stress tasks completed in a traditional behavioral laboratory, which may be due to apprehension of fMRI that elicits an anticipatory stress response. The present study investigated whether anticipatory stress is greater prior to research completed in an MRI environment than in a traditional behavioral laboratory. Anticipatory stress (indexed by cortisol) was greater prior to tes...

Using real-time fMRI brain-computer interfacing to treat eating disorders.

Real-time functional magnetic resonance imaging based brain-computer interfacing (fMRI neurofeedback) has shown encouraging outcomes in the treatment of psychiatric and behavioural disorders. However, its use in the treatment of eating disorders is very limited. Here, we give a brief overview of how to design and implement fMRI neurofeedback intervention for the treatment of eating disorders, considering the basic and essential components. We also attempt to develop potential adaptations of fMRI neurofeedba...

Running for extinction? Aerobic exercise as an augmentation of exposure therapy in panic disorder with agoraphobia.

Exposure-based Cognitive Behavioral Therapy (eb-CBT) represents the most evidence-based psychotherapeutic approach in anxiety disorders. However, its efficacy may be limited by a delay in onset of action and a substantial number of patients does not respond sufficiently to treatment. In this context, aerobic exercise was found to be effective in reducing clinical anxiety as well as to improve (elements of) disorder-specific CBT in some mental disorders. We therefore investigated the effect of aerobic exerci...

Prolonged grief reactions after old age spousal loss and centrality of the loss in post loss identity.

The loss of a spouse is a major life event. Previous research found that centrality of the loss to one's identity using Centrality of Event Scale (CES) is related to complicated bereavement reactions, such as depression, posttraumatic stress symptoms (PTS), and prolonged grief symptoms (PGS). This study aims to examine loss-centrality in elderly bereaved people up to 4 years post loss, to determine the relation of loss-centrality to complicated bereavement reactions, such as PGS, depression, and PTS, and to...

Salvage therapy post pomalidomide-based regimen in relapsed/refractory myeloma.

The combination of pomalidomide and low-dose dexamethasone (Pom-Dex) has proved effective and safe in patients with end-stage relapsed/refractory multiple myeloma (RRMM), otherwise characterized by a very poor outcome. MM remains an incurable disease with unavoidable relapses, and the outcome after pomalidomide is still dismal. However, some patients demonstrate prolonged survival even beyond pomalidomide therapy.We sought to analyze the treatment of RRMM patients following Pom-Dex therapy and the response ...

Post-traumatic stress disorder and risk of osteoporosis: A nationwide longitudinal study.

Several studies suggested a relationship between stress and related mental illnesses, such as depression and osteoporosis. However, it was unclear whether patients with post-traumatic stress disorder (PTSD) were at risk of developing osteoporosis in later life. In this study, 6,041 patients with PTSD and 24,164 age- or sex-matched controls were enrolled between 2002 and 2009 in our study and followed up to the end of 2011. Cases of osteoporosis were identified during the follow-up. Patients with PTSD had an...

A Monte Carlo Simulation Approach for Beta-Lactam Dosing in Critically Ill Patients Receiving Prolonged Intermittent Renal Replacement Therapy.

Cefepime, ceftazidime, and piperacillin/tazobactam are commonly used beta-lactam antibiotics in the critical care setting. For critically ill patients receiving prolonged intermittent renal replacement therapy (PIRRT), limited pharmacokinetic data are available to inform clinicians on the dosing of these agents. Monte Carlo simulations (MCS) can be used to guide drug dosing when pharmacokinetic trials are not feasible. For each antibiotic, MCS using previously published pharmacokinetic data derived from cri...

The association between estradiol levels, hormonal contraceptive use, and responsiveness to one-session-treatment for spider phobia in women.

Preclinical studies have demonstrated that conditioned fear extinction is impaired in females with low endogenous levels of the sex hormone estradiol, due to menstrual fluctuations or hormonal contraceptive use. As fear extinction is a laboratory model of exposure therapy for anxiety and trauma disorders, here we assessed the hypothesis that treatment outcomes may be diminished when exposure therapy occurs during periods of low estradiol. 90 women with spider phobia (60 cycling and 30 using hormonal contrac...

Prenatal exposure to disaster-related traumatic stress and developmental trajectories of temperament in early childhood: Superstorm Sandy pregnancy study.

Little is known about the impact of prenatal maternal stress (PNMS) on the developmental trajectory of temperament and few studies have been able to incorporate a natural disaster as a quasi-experimental stressor. The current study investigated PNMS related to Superstorm Sandy ('Sandy'), a hurricane that struck the New York metropolitan area in October 2012, in terms of objective exposure during pregnancy, subjective stress reaction as assessed by maternal symptoms of post-traumatic stress, and their impact...

Acute Assessment of Traumatic Brain Injury and Post-Traumatic Stress After Exposure to a Deployment-Related Explosive Blast.

Traumatic brain injury (TBI) and post-traumatic stress disorder (PTSD) are two of the signature injuries in military service members who have been exposed to explosive blasts during deployments to Iraq and Afghanistan. Acute stress disorder (ASD), which occurs within 2-30 d after trauma exposure, is a more immediate psychological reaction predictive of the later development of PTSD. Most previous studies have evaluated service members after their return from deployment, which is often months or years after ...

Patterns and predictors of posttraumatic stress disorder in refugees: A latent class analysis.

Although elevated rates of posttraumatic stress disorder (PTSD) have been well-documented in refugees, no study has investigated the heterogeneity of DSM-5 PTSD symptomatology in such populations. This study aimed to determine whether there are unique patterns of DSM-5 defined PTSD symptomatology in refugees, and investigate whether factors characteristic of the refugee experience, including trauma exposure and post-migration stress, predict symptom profiles.

Differential effects of childhood neglect and abuse during sensitive exposure periods on male and female hippocampus.

The hippocampus is a highly stress susceptible structure and hippocampal abnormalities have been reported in a host of psychiatric disorders including major depression and post-traumatic stress disorder (PTSD). The hippocampus appears to be particularly susceptible to early life stress with a graded reduction in volume based on number of types (multiplicity) or severity of maltreatment. We assessed whether the most important predictors of adult hippocampal volume were multiplicity, severity or duration of e...

The mediation effect of PTSD, perceived job stress and resilience on the relationship between trauma exposure and the development of depression and alcohol use problems in Korean firefighters: A cross-sectional study.

Firefighters constitute a high-risk group for depression and alcohol use disorders (AUDs) due to frequent exposure to trauma. Perceived job stress and resilience are powerful factors affecting the occurrence of depression and AUDs; however, research on this subject is scarce.

Two weeks of variable stress increases gamma-H2AX levels in the mouse bed nucleus of the stria terminalis.

Recent reports demonstrate that DNA damage is induced, and rapidly repaired, in circuits activated by experience. Moreover, stress hormones are known to slow DNA repair, suggesting that prolonged stress may result in persistent DNA damage. Prolonged stress is known to negatively impact physical and mental health; however, DNA damage as a factor in stress pathology has only begun to be explored. Histone H2A-X phosphorylated at serine 139 (γH2AX) is a marker of DNA double strand breaks (DSB), a type of damag...

Suppressed acoustic startle response in traumatic brain injury masks post-traumatic stress disorder hyper-responsivity.

An exaggerated acoustic startle reflex (ASR) is a clinical indicator of anxiety disorders, such as post-traumatic stress disorder (PTSD). Given the prevalence of PTSD following traumatic brain injury (TBI), we studied the effects of TBI on ASR. Adult Sprague Dawley rats exposed to moderate controlled cortical impact injury model of TBI displayed suppression of ASR intensity and sensitivity. As patients with PTSD have been shown to display hyperactive startle responses, the present discrepant observation of ...

Trauma, attentional dysregulation, and the development of posttraumatic stress: An investigation of risk pathways.

Fundamental questions regarding the nature and function of attentional bias (AB) to threat in the etiology of posttraumatic stress disorder (PTSD) remain unanswered. We tested the temporal interplay between trauma exposure, dysregulated attentional processing of threatening information pre- and post-trauma, and the development of posttraumatic intrusions.

Meta-Analysis of the Association Between Autobiographical Memory Specificity and Exposure to Trauma.

Cognitive models of emotional disorders suggest that reduced autobiographical memory specificity that results from exposure to traumatic events may play an important role in the aetiology and maintenance of these disorders. However, there has yet to be a comprehensive meta-analysis of the association between trauma exposure and memory specificity, and the role of posttraumatic stress symptoms on this association. We searched PsycINFO and MEDLINE databases and extracted data from studies regarding the mean n...

Targeting Kruppel-like Factor 9 in Excitatory Neurons Protects against Chronic Stress-Induced Impairments in Dendritic Spines and Fear Responses.

Stress exposure is associated with the pathogenesis of psychiatric disorders, including post-traumatic stress disorder (PTSD) and major depressive disorder (MDD). Here, we show in rodents that chronic stress exposure rapidly and transiently elevates hippocampal expression of Kruppel-like factor 9 (Klf9). Inducible genetic silencing of Klf9 expression in excitatory forebrain neurons in adulthood prior to, but not after, onset of stressor prevented chronic restraint stress (CRS)-induced potentiation of contex...

Nicotine exposure leads to deficits in differential cued fear conditioning in mice and humans: a potential role of the anterior cingulate cortex.

Stress and anxiety disorders such as posttraumatic stress disorder (PTSD) are characterized by disrupted safety learning. Tobacco smoking has been strongly implicated in stress and anxiety disorder symptomatology, both as a contributing factor and as a vulnerability factor. Rodent studies from our lab have recently shown that acute and chronic nicotine exposure disrupts safety learning. However, it is unknown if these effects of nicotine translate to humans. The present studies addressed this gap by adminis...

Neuroprotective Effects of AEOL10150 in a Rat Organophosphate Model.

Prolonged seizure activity or status epilepticus (SE) is one of the most critical manifestations of organophosphate (OP) exposure. Previous studies in our laboratory have demonstrated that oxidative stress is a critical mediator of SE-induced neuronal injury. The goal of this study was to determine if diisopropylflurorphoshate (DFP) exposure in rats resulted in oxidative stress and whether scavenging reactive oxygen species (ROS) attenuated DFP-induced neurotoxicity. DFP treatment increased indices of oxida...

Gastrografin may reduce time to oral diet in prolonged post-operative ileus: a pooled analysis of two randomized trials.

Gastrografin has been suggested as a rescue therapy for prolonged post-operative ileus (PPOI) but trial data has been inconclusive. This study aimed to determine the benefit of gastrografin use in patients with PPOI by pooling the results of two recent randomized controlled trials assessing the efficacy of gastrografin compared to placebo given at time of PPOI diagnosis.

Chronic Stress Exposure Reduces Parvalbumin Expression in the Rat Hippocampus through an Imbalance of Redox Mechanisms: Restorative Effect of the Antipsychotic Lurasidone.

Psychiatric disorders are associated with altered function of inhibitory neurotransmission within the limbic system, which may be due to the vulnerability of selective neuronal subtypes to challenging environmental conditions, such as stress. In this context, parvalbumin (PVB) positive GABAergic interneurons, which are critically involved in processing complex cognitive tasks, are particularly vulnerable to stress exposure, an effect that may be the consequence of dysregulated redox mechanisms.
