The effects of minocycline on neuroinflammation in rats with post-traumatic stress disorder / 神经解剖学杂志

Objective:To investigate the effect of minocycline on neuroinflammation of rats with post-traumatic stress disorder(PTSD).Methods:The rat model of PTSD was prepared by a single prolonged stress(SPS)method,and the rats were treated with minocycline(PTSD+Mino group)or normal saline(PTSD group)by gavage.The behavioral changes of rats were detected by light-dark box test.The expression of ionized calcium-binding adapter molecule 1(Iba-1)in hippocampus was detected by immunohistochemical staining.The contents of IL-1β and TNF-α in hippocampus were detected by ELISA,and the expression levels of IL-1β and TNF-α mRNA in hippocampus were detected by real-time RT-PCR(qRT-PCR).Results:After 3 days of SPS stimulation,the anxiety-like behavior of rats was obvious,the expression of Iba-1 in hippocampus was increased,and the contents of IL-1β and TNF-α in hippocampus were in-creased.Minocycline treatment significantly reduced anxiety-like behavior and decreased the expression of Iba-1 in the hippocampus of PTSD rats.Meanwhile,minocycline treatment also decreased the levels of IL-1β and TNF-α mRNA and protein in the hippocampus.Conclusion:Minocycline can improve the anxiety-like behavior of PTSD rats by inhibiting the activation of microglia.

Experience with Chikujountanto (Untanto) for Trauma- and Stressor- Related Disorders / 日本東洋医学雑誌

I report five cases in which chikujountanto and untanto were effective for trauma and stressor-related disorders. Post-traumatic stress disorder (PTSD) and acute stress disorder (ASD) are both psychiatric disorders that occur as a reaction to severe stress, and are distinguished by the duration of the disorder. Chikujountanto is indicated for those who have cough and insomnia after late yang stage pattern in case of cold, and for chronic diseases such as depression and sleep disorders, and is applied to various psychiatric disorders. In this paper, I cite the grounds for applying chikujountanto to PTSD from the classics, examine the similarities and differences with other Kampo medicines reported to be used for PTSD from the characteristics of the constituent crude drug centered on Huang lian. I also infer the relationship between the therapeutic mechanism of Kampo and neuroinflammation. Regardless of the severity of the trauma, rapid administration of this drug is expected to hasten the healing process.

Abnormal neuronal activation associated with fear memory extinction in the hippocampus of a PTSD mouse model / 神经解剖学杂志

Objective:To analyze the differences in neuronal activation during fear memory extinction in various sub-regions of the hippocampus in post-traumatic stress disorder(PTSD)mice.Methods:Two immediate early gene-pro-tein labeling strategies were employed to label neurons associated with fear extinction in PTSD mice.In the first group,Arc protein in hippocampal neurons was labeled and observed through immunofluorescence staining in wild-type mice.In the second group,Fos-CreERT2;Ai9 transgenic mice were injected with tamoxifen 23 hours prior to inducing fear memory extinction,and the relevant neurons were labeled with fluorescent proteins for observation.The number of labeled hippocampal neurons and the dendritic branch structure were analyzed to compare the activation levels of hipp-ocampal neurons and the plasticity of neuronal dendrites.Results:The two groups of Arc and Fos positive neurons were mainly distributed in the dorsal hippocampus,in which Arc protein chromogenic was enriched in CA3 and DG subre-gions,while CA1 and CA2 subregions were scattered,while Fos-positive neurons were enriched in the DG subregion of hippocampus and scattered in CA1,CA2 and CA3 subregions.Compared to the control group,there was no significant difference in the number of neurons expressing Arc protein in each subregion of the hippocampus in the PTSD group.The number of Fos-positive neurons in CA1,CA3 and DG subregions in the hippocampus of the PTSD group was signifi-cantly increased(P＜0.01).The dendritic branches of neurons in the hippocampal region were observed and analyzed in Fos-CreERT2;Ai9 mice from both groups,but no significant changes were found.Conclusion:Abnormal activation of neurons occurs in different subregions of the hippocampus during fear extinction in PTSD mice,although there are no significant plasticity changes in the dendritic branches of the activated neurons.

The effects of exercise on the expression of ferroptosis-related proteins in mice with post-traumatic stress disorder / 神经解剖学杂志

Objective:The study aimed to investigate the effects of exercise on the expression of ferroptosis-related proteins and the associated mechanisms in a post-traumatic stress disorder(PTSD)model induced by transient foot shock.Methods:Thirty-five male C57BL/6J mice(8 weeks old)were randomly divided into three groups:Control group,PTSD group,and Exe+PTSD group.PTSD model mice were established by foot-shock and PTSD behaviors were assessed using a fear conditioning box.Iron distribution areas were detected by Fe3+staining.Western Blot analysis were performed to determine the expression level of ferroptosis-related proteins in the mice.Results:Compared to the control group,the freezing time and Fe3+distribution areas in the cortex and hippocampus were significantly increased in the mice with PTSD(P＜0.05).The levels of ferroportin1(FPN1),glutathione peroxidase 4(GPX4),and brain-derived neurotrophic factor(BDNF)proteins were significantly decreased(P＜0.05),while the expression of high mobility group box 1(HMGB1)protein was significantly elevated(P＜0.05).Exercise significantly reduced freezing time and Fe3+accumulation in the cortex and hippocampus(P＜0.05),and it also up-regulated the expression of FPN1,GPX4,and BDNF proteins(P＜0.05),while down-regulating HMGB1 expression compared to the PTSD group(P＜0.05).Conclusion:This study demonstrates that PTSD induces the ferroptosis-related pathway in mice,and exercise can inhibit iron accumulation and reverse the expression of ferroptosis-related proteins induced by PTSD,there-by alleviating PTSD-like behavior in mice.

As raízes do trauma: uma revisão sobre a história do psicotraumatismo / The roots of trauma: a review of the history of psychotrauma

Resumo A percepção do papel do trauma psicológico na origem de problemas psiquiátricos aumentou e diminuiu ao longo da história da psiquiatria. Com a concepção do transtorno de estresse pós-traumático (TEPT), entretanto, as sociedades ocidentais presenciaram uma profunda expansão do discurso do traumatismo na interpretação de experiências humanas devastadoras, como catástrofes, genocídios, desastres e epidemias. A partir de revisão bibliográfica integrativa, este artigo analisa alguns dos determinantes históricos e epistemológicos que fundamentam o surgimento da memória traumática e o estabelecimento do trauma como campo semântico que orienta respostas clínicas e estratégias políticas no campo das ciências humanas e da saúde.

Abstract Perceptions of the importance of the role of psychological trauma in the origins of psychiatric problems have oscillated throughout the history of psychiatry. However, since the conception of post-traumatic stress disorder (PTSD), western societies have witnessed a marked expansion of the discourse of trauma in the interpretation of devastating human experiences like catastrophes, genocides, disasters, and epidemics. Through an integrative literature review, this article analyzes some of the historical and epistemological determinants behind the emergence of traumatic memory and the establishment of trauma as a semantic field that orients clinical responses and political strategies in the field of the humanities and the health sciences.

Neurobiological mechanisms in the regulation of conditioned fear memory by the retrieval-extinction paradigm / 中华行为医学与脑科学杂志

Fear memories are temporarily suppressed after repeated retrieval, a phenomenon known as memory extinction.How to reduce or even eliminate fear memory is the key to the treatment of fear related diseases such as post-traumatic stress disorder(PTSD). A single extinction training based on Pavlov's fear regulation task could only inhibit the expression of conditioned fear memory traces, but it could not eliminate the acquired conditioned fear memory. However, according to the reconsolidation theory based on memory, the retrieval-extinction paradigm has a more lasting effect on the erasure and rewriting of fear memory, and can effectively prevent the return of fear memory. Studies have shown that extraction-regression is closely related to a variety of neurotransmitter receptors such as glutamate receptor(GluR), dopamine receptor(DAR), L-type voltage-gated calcium channels(LVGCs) and cannabinoid. Moreover, its effect is closely related with factors such as retrieval-extinction memory stage. At present, most of the researches on extracted boundary conditions only stay at the level of behavior, with little understanding and exploration on the level of molecular mechanism. From the perspective of molecular neurobiology, with different stages of memory and different types of receptors and molecular mechanisms, this research reviewed the mechanisms of retrieval-extinction in recent years.It provided valuable signaling pathways, molecular targets and research directions for the treatment of fear-related diseases such as PTSD.

The effect of trauma type on the severity of Post-Traumatic Stress Disorder (PTSD) symptoms

Abstract Objective: The high prevalence of trauma exposure calls for detailed research on how trauma type affects the development of Post-Traumatic Stress Disorder (PTSD). Therefore, the aim of our study was to investigate the effects of the type of trauma on the severity of symptoms, anxiety, depression, and dissociative experiences in the PTSD patient population. Method: The sample of the study consists of 80 volunteer PTSD patients (20 sexual trauma, 20 work accidents, 20 traffic accidents and 20 combat related trauma). Once the severity of symptoms was determined in all subjects by the Clinician-Administered PTSD Scale (CAPS), Beck Depression Inventory, Beck Anxiety Inventory and Dissociative Experiences Scale (DES) were applied. Results: A statistically significant difference were found between trauma types with regard to age, time without treatment, and the total and subscale scores obtained in DES and CAPS. It was found that in the group that has PTSD diagnosis related to sexual trauma, the length of the time without treatment, DES and CAPS scores. Conclusion: The study we conducted showed that PTSD continued more severe and resistant after a sexual trauma. Moreover, specific type of trauma was significant in PTSD patients.

Effect of social isolation on the behavior of rat models of post-traumatic stress disorder established by single-prolonged stress / 中国比较医学杂志

Objective To establish a rat model of post-traumatic stress disorder(PTSD)through single-prolonged stress(SPS)and to observe the effect of social isolation on the behavior of the SPS model rats. Methods A total of 36 rats were randomly divided into the normal group, SPS model group and SPS combined with social isolation group. The rats in both SPS model group and SPS combined with social isolation group were modeled by single-prolonged stress,and the rats in the SPS combined with social isolation group were raised separately after modelling. The weight gaining,the total movement distance in open field test,the frequency of grid crossing,the single maximum movement distance,and the freezing frequency and time durations in the freezing behavior test were measured after 7 days of modeling. Results Compared with the normal group,the weight gaining and the single maximum movement distance of the rats in the SPS model group were significantly decreased(P < 0.01),as well as the total movement distance and the frequency of grid crossing(P < 0.05),while the freezing frequency and time in the freezing behavior test were significantly increased(P < 0.01). Compared with the normal group,the weight gaining and crossing times of the rats in the SPS combined with social isolation group was decreased(P <0.05),and the freezing frequency and time durations in the freezing behavior test were increased(P < 0.05). In addition, compared with the SPS model group,the total movement distance in the open field test,the frequency of grid crossing and the single maximum movement distance of the rats in the SPS combined with social isolation group were increased(P < 0.05). Conclusions The rat model of post-traumatic stress disorder is successfully established by single-prolonged stress, and 7 days of social isolation may alleviate the anxiety state of SPS model rats.

Prevalence And Perceived Severity Of Post-Traumatic Stress Disorder Among Flood Victims In Kuala Terengganu, Malaysia

Floods can lead to direct economic and property losses and result not only in physical injuries and deaths but also in psychological trauma. Post-traumatic stress disorder (PTSD) is a commonly used indicator to evaluate psychological injuries after disaster. This study aimed to determine the relationship between PTSD prevalence and related perceived severity of post flood impact by economical, non-economical and flood status severity domains besides relevant socio-demographic factors according to gender specific analysis. This cross-sectional study was conducted among community in Kampung Hulu Takir, Kuala Terengganu, Malaysia in 2015 two weeks after flood. It included a total of 98 males and 110 females aged 18 years and above. Data was collected by interview-guided questionnaire to determine the prevalence of PTSD. SPSS version 21.0 was used for analysis of the relationship between socio demographic factors, perceived economic, non-economic and flood severity with PTSD. Finally chi square test was used to assess the predictors of PTSD according to gender. The prevalence of PTSD was 9.2% in males and 10.9% in females, giving a total of 10.1%. Significantly higher prevalence of PTSD was found in severely perceived economic and flood impact categories (33.3% and 23.8% in males; 23.8 % and 37.5% in females) and giving in overall 44.0% and 31.3 % respectively. Effective PTSD management strategies targeting females post flood victims who severely perceived economically and nature flood impact should be implemented in order to prevent further consequences of PTSD.

Combined psychopharmacological and psychosocial approaches and the relevance of therapeutic jurisprudence and religion in the successful management of battered woman's syndrome: A case report

INTRODUCTION: Although Battered Woman Syndrome is not listed in the DSM 5 and the ICD 10 as an official diagnosis, it is undeniable that women suffering Intimate Partner Violence (IPV) experience the same cycle of violence, suffer from a common range of symptoms, and have a predictable prognosis. While psychosocial guidelines and support are available, like in our Women and Child Protection Units (WCPU), there is also a gap in the clinical guidelines in treating and managing these cases, which might present with a combination of posttraumatic and depressive symptomatology. In this report, we discuss the case of a 32 year old woman who was subjected to severe physical and emotional abuse by her longtime romantic partner. She consulted at our center seeking help for a psychiatric evaluation for the case she was going to pursue in court but it was apparent she was suffering from posttraumatic, somatic, and depressive symptoms. Supportive therapy was initially done and she was started on Escitalopram and low dose Quetiapine for sleep problems. As her case started gathering steam, issues about the court process, possible setback with her church and possible retaliation from her partner weighed heavily on her. Possible issues were discussed beforehand and successfully faced up to her partner in a church related tribunal and in the fiscal's office. Using an Eye Movement Desensitization and Reprocessing(EMDR) variant, Unfinished Trauma Episode Protocol (U-TEP), her posttraumatic symptoms were eventually addressed. As she started having faith in the legal system and her church, she had restored self-esteem, was active in her social circle and become an advocate in helping other women get proper treatment and to fight for their rights. Besides the clinician advocated treatment along with the services delivered via the WCPU network, the perception of getting justice from social institutions like the judiciary and the church helped in the recovery of this patient. Clinicians dealing with Battered Woman Syndrome should be aware of issues the patient might go through the stages of her fight and that the process of seeking for justice is also a process of mental healing.

Effects of Resilience, Post-traumatic Stress Disorder on the Quality of Life in Patients with Breast Cancer

PURPOSE: The purpose of this study was to identify relationships of resilience, Post-Traumatic Stress Disorder(PTSD), and quality of life of breast cancer patients. The findings from this study would provide baseline data needed for nursing intervention. METHODS: A sample of 129 breast cancer patients was recruited from three hospitals in J and C cities in Korea. The survey was conducted with participants by utilizing self-reported questionnaires. RESULTS: Quality of life showed statistically significant differences on religion (t=2.11, p=.033) and hobby (t=2.79, p=.006). Resilience and PTSD had a negative correlation (r=-.22, p=.010). Resilience and quality of life of the participants had a positive correlation (r=.58, p<.001), whereas PTSD and quality of life had a negative correlation (r=-.45, p<.001). Significant predictors of quality of life were resilience and PTSD. These variables explained 44.9% of the variance in quality of life. CONCLUSION: Findings indicate that as resilience of breast cancer patients rose higher and PTSD got lower, their quality of life increased. Based on these results, nursing interventions directed towards improving resilience and relieving PTSD is proposed.

Validation of the Korean Version of the Children's Revised Impact of Event Scale

OBJECTIVE: This study examined the psychometric properties of the Korean version of the Children's Revised Impact of Event Scale (CRIES) and its validity as a screening instrument for the post-traumatic stress disorder (PTSD). METHODS: The study population consisted of two samples. The clinical sample consisted of 60 child and adolescent patients from the Department of Neuropsychiatry, Ilsan Paik Hospital, Inje University College of Medicine. The normal sample consisted of 291 students from four schools (primary, middle, and high schools). We administered four self-report questionnaires (the CRIES, Child Reports of Post-traumatic Symptoms [CROPS], State-Trait Anxiety Inventory for Children [STAI-C], and Children's Depression Inventory [CDI]) to 351 children and adolescents after obtaining informed consent from all participants and their parents. RESULTS: The CRIES showed good reliability (Cronbach's alpha for the full scale and subscales ranged from 0.85 to 0.93). The total CRIES score was positively correlated with CROPS, STAI-C, and CDI. Confirmatory factor analysis indicated that a three-factor structure for the CRIES (intrusion, avoidance, and hyper-arousal) had a significantly better fit than a two-factor model (intrusion/hyper-arousal and avoidance). Receiver operating characteristic curve analysis indicated that a cutoff of 26 offered the optimum predictive point. That is, this cutoff maximized the balance between sensitivity (0.88) and specificity (0.85). Using this cutoff, the positive predictive value was 0.86, and the negative predictive value was 0.99. CONCLUSION: These findings imply that the CRIES is a highly accurate diagnostic test in clinical settings.

Estrés postraumático en escolares a 8 meses del 27F / Post-traumatic stress disorder in children eight months after february 27, 2010

Introduction: there are several epidemiological studies regarding the incidence of post-traumatic stress disorder (PTSD) in children exposed to natural disasters. Objective: to describe the prevalence of PTSD in a school-age population in a coastal town from the Maule Region, 8 months after the earthquake/tsunami in february 2010, and to compare differences among PTSD groups of symptom (re-experiencing, avoidance and activation) according to demographic variables such as age, grade, gender and family type. Methodology: the Child PTSD Symptom Scale (CPSS), validated in Chile in 2009, was used in 89 children between 3rd and 6th grade, corresponding to 94.7 percent of the children enrolled in the local school in such classes. Data are analyzed by gender, age, grade and type of family. 89 surveys were applied, 59.6 percent were male and 40.4 percent female aged 8-13. Results: 40.4 percent of children had symptoms consistent with PTSD, with higher incidence in women and younger children; the most significant association among women was age. Both groups (women and young children) presented the highest scores on all group of symptoms. There were no differences by type of family. Conclusions: the incidence of PTSD measured by CPSS scale in the study population was 40.4 percent, considered to be among the highest percentages reported in the international literature.
