Posttraumatic stress disorder (PTSD) is characterized by the occurrence of a traumatic event that is beyond the normal range of human experience. The future of PTSD treatment may specifically target the molecular mechanisms of PTSD. In the US, approximately 20% of adults report taking herbal products to treat medical illnesses. L-theanine is the amino acid in green tea primarily responsible for relaxation effects. No studies have evaluated the potential therapeutic properties of herbal medications on gene expression in PTSD. We evaluated gene expression in PTSD-induced changes in the amygdala and hippocampus of Sprague-Dawley rats. The rats were assigned to PTSD-stressed and nonstressed groups that received either saline, midazolam, L-theanine, or L-theanine + midazolam. Amygdala and hippocampus tissue samples were analyzed for changes in gene expression. One-way ANOVA was used to detect significant difference between groups in the amygdala and hippocampus. Of 88 genes examined, 17 had a large effect size greater than 0.138. Of these, 3 genes in the hippocampus and 5 genes in the amygdala were considered significant (P<0.05) between the groups. RT-PCR analysis revealed significant changes between groups in several genes implicated in a variety of disorders ranging from PTSD, anxiety, mood disorders, and substance dependence.

The aim of this study was to analyse frequency of embitterment in war veterans with Posttraumatic stress disorder (PTSD) as well as the potential impact of embitterment on the development of chronic PTSD.Patients and methodsIt was analyzed 174 subjects (from Health Center Zivinice/mental health center) through a survey conducted in the period from March 2015 to June 2016, of which 87 war veterans with PTSD and control subjects 87 war veterans without PTSD. The primary outcome measure was the post-traumatic embitterment disorder self-rating scale (PTED Scale) who contains 19 items designed to assess features of embitterment reactions to negative life events. Secondary efficacy measures included the clinician-administered PTSD scale–V (CAPS), the PTSD checklist (PCL), the combat exposure scale (CES), the Hamilton depression rating scale (HAM-D), the Hamilton anxiety rating scale (HAM-A) and the World health organization quality of life scale (WHOQOL-Bref). All subjects were male. The average age of patients in the group war veterans with PTSD was 52.78 ± 5.99. In the control group, average age was 51.42 ± 5.98. Statistical data were analyzed in SPSS statistical program.ResultsComparing the results, t-tests revealed significant difference between group veterans with PTSD and control group (t = −21,21, P < 0.0001). War veterans group with PTSD (X = 51.41, SD = 8,91), control group (X = 14.39, SD = 13.61).ConclusionEmbitterment is frequent in war veterans with PTSD.Disclosure of interestThe authors have not supplied their declaration of competing interest.

This study investigated posttraumatic stress disorder (PTSD) symptoms on Korean journalists and the contributing variables. Predicting variables included the exposure to traumatic events, coping strategy, social support, optimism, negative beliefs, and the journalists’ occupational perspectives. A total of 367 Korean journalists participated in the survey. The findings revealed that, first, Korean journalists had suffered severely from PTSD symptoms according to the prevalence rate. Second, the extent of traumatic event exposure, the length of career, the use of dysfunctional coping strategy, a lack of social support, and negative beliefs were identified as significantly related variables. Finally, occupational perspectives showed meaningful associations with development of the symptoms. This study provided an empirical analysis of Korean journalists’ experiences of traumatic events and psychological stress for the first time.

Preoccupied Attachment

This study examined Posttraumatic Stress Disorder in relation to secure and insecure attachment styles based on data collected in a sample of 81 Belgian security workers. All had experienced one traumatic event in the previous year. The sample was divided into a securely attached and an insecurely attached group. The three PTSD symptom scales, Re-experiencing, Avoidance, and Hyperarousal, differentiated significantly between the two attachment groups; the dismissive attachment style was negatively related to PTSD. Individuals with a positive view of themselves and a negative view of others have less risk of developing PTSD than those with a fearful or preoccupied attachment style. A relationship between the dismissive attachment style with grandiose narcissism seems possible. Interest has been expressed in medical approaches; therefore, the importance of medical research on PTSD is emphasized.

The Impact

This paper describes three studies of the reliability and validity of a newly revised version of the Purdue Posttraumatic Stress Disorder scale (PPTSD-R). The PPTSD-R is a 17-item questionnaire that yields four scores: Reexperiencing, Avoidance, Arousal, and Total. It is highly internally consistent (α = .91), and the scores are relatively stable across time. The PPTSD-R is highly correlated with other measures of PTSD symptomatology and moderately correlated with measures of related psychopathology, providing preliminary support for the measure's convergent and discriminant validity. It reliably distinguishes between groups of people who were and were not traumatized, it is sensitive to the impact of different types of traumatic events, and (within a clinical sample) it discriminates between those who did and did not seek treatment for difficulty coping with the traumatic event being assessed. The PPTSD-R shows promise as a measure of PTSD symptoms in the college population.

Posttraumatic stress disorder (PTSD) differs from other categories that are underdoing diagnostic epidemics, in that its treatment is primarily based on psychotherapy. PTSD tends to be overdiagnosed when clinicians attribute, rightly or wrongly, symptoms to a traumatic event. Yet most people who undergo trauma do not develop PTSD, and people without trauma can have similar symptoms. This chapter shows how the construct of PTSD arose historically. A problematic DSM definition, in relation both to the nature of stressors and the links between stress and outcome, causes PTSD to be overdiagnosed. The result is that many patients are receiving the wrong kind of psychotherapy for their problems.

INTRODUCTION: Posttraumatic Stress Disorder (PTSD) is a psychiatric syndrome known since 1980 with multiple names in the military field. Its etiology is multicausal, whose predominant factor is the lack of adaptation and managing with events considered traumatic. Objective. To describe the clinical characteristics such as the type of psychological and pharmacological treatment received by the naval military with diagnosis of Posttraumatic Stress Disorder at the Psychiatric Unit of Cartagena’s Naval Hospital.METHODOLOGY: A descriptive, retrospective cross-sectional study with an associative approach (Crosstabulation). The sample was 242 navy subjects with PTSD diagnosis. The information was collected with a data collection form of medical records. The information analysis was developed through the program SPSS ® 21.0. Chi2 and value of p≤0.05 calculation was applied through the crossing of variables.RESULTS: The most prevalent type of traumatic event was the one represented by combat with the presence of depressive disorders and anxiety with a value of p≤0.05.CONCLUSIONS: The PTSD severity is related to the severity of the event, in addition if the trumatic event was repetitive.

The Impact

Background: Mental imagery of the future has clear clinical importance, although little is known about intrusive, prospective imagery of personally-relevant events. Currently, no measure is available to assess this. Aims: The Impact of Future Events Scale (IFES) was created to assess the impact of intrusive, prospective, personally-relevant imagery. It was examined in relation to predictions about dysphoria. Method: To form the IFES, the IES-R (a measure of the impact of a past traumatic event on posttraumatic stress disorder symptomatology such as intrusive re-experiencing) was adapted item-by-item to assess intrusive “pre-experiencing” and imagery of specific, future events. Participants (N = 75) completed the IFES and assessments of depression, anxiety and general imagery use. Results: As predicted, the IFES significantly and positively correlated with depression scores. Analyses using subgroups of non-dysphoric and mild-dysphoric participants confirmed that the mild-dysphoric group reported significantly higher IFES scores, indicating higher levels of pre-experiencing of the future and related hyperarousal and avoidance. Conclusions: IFES provides a measure of the impact of “pre-experiencing” in the form of intrusive prospective, personally-relevant imagery, with sensitivity to group differences on the basis of depression scores. Further research is required to extend these finding into clinical depression and other psychopathological conditions.
