RESUMO

Victims of traumatic events that involve repeated interpersonal aggression and low or no chance of escape frequently report intense Self-Conscious Emotions (SCEs), such as Shame, Guilt, and Humiliation. Humiliation is the reaction to a forced loss of status and is hypothesized to have unique contributions to the development and maintenance of Posttraumatic Stress Disorder (PTSD) and Complex Posttraumatic Stress Disorder (CPTSD). However, previous studies did not include humiliation or did not simultaneously probe the relative contribution of each SCE to posttraumatic symptoms. This study aimed to investigate the dynamics between specific SCEs and trauma-related symptomatology in the general population who suffered a form of complex trauma. Four hundred forty-nine people (77.11% women) exposed to domestic violence and sexual abuse answered an online survey. We investigated whether each emotion would accurately predict probable PTSD and CPTSD levels above the proposed cutoff. We estimated a network model to understand the dynamics of their interactions and whether the traumatic event type would moderate relationships between SCEs and posttraumatic stress symptoms, comparing networks of two types of complex trauma. No SCE predicted PTSD, but humiliation was a predictor of CPTSD while controlling for Shame and Guilt. Humiliation was also the most central SCE domain in the networks of both traumatic events. Our results stress the relevance of Humiliation to understanding posttraumatic stress symptoms and the necessity to consider humiliation when studying the emotional processing in complex trauma.

RESUMO

Cumulative trauma is usually devastating and can lead to severe psychological consequences, including posttraumatic stress disorder (PTSD). Exposure to various types of traumas, particularly during childhood, can be even more deleterious than the sheer number of events experienced. This epidemiological study is the first to investigate the impact of discrete childhood traumatic exposure on the risk of developing lifetime PTSD in a representative sample of the general population of the two biggest Brazilian cities. Participants were aged between 15 and 75 years old, living in São Paulo and Rio de Janeiro, Brazil, who had experienced traumatic events (N = 3,231). The PTSD diagnosis was assessed using the DSM-IV criteria through the version 2.1 of Composite International Diagnostic Interview. To operationalize childhood cumulative trauma, we considered the sum of 15 different childhood trauma categories that occurred before PTSD onset. The final multivariate logistic regression model indicated a strong relationship between the number of discrete types of childhood traumas and the likelihood of the lifetime PTSD development. The lifetime PTSD risk increased 28 % with each different type of childhood trauma when adjusted by confounds. Our study strengthens the evidence associating childhood cumulative trauma to increased lifetime PTSD risk.

RESUMO

Internet-delivered cognitive-behavioral therapy (I-CBT) is effective in treating post-traumatic stress disorder (PTSD) symptoms, offering enhanced accessibility and cost-effectiveness. However, it's important to note that these technologies may not be suitable for all age groups. Therefore, we conducted a systematic review and meta-analysis to determine if the effectiveness of I-CBT in treating PTSD varies based on the patients' mean age. We conducted a systematic review of the literature, focusing on randomized controlled trials (RCTs) in the ISI Web of Science, PubMed/MEDLINE, and PsycINFO databases. Following this, we performed a meta-analysis and evaluated the risk of bias using the Cochrane risk of bias quality assessment tool. In this study, we examined patient-related factors (civil or military status, age, and gender), clinical characteristics (baseline PTSD severity and type of trauma), and treatment characteristics (type of intervention, synchronous or asynchronous delivery, and the number of sessions) as independent variables. The dependent variable was the reduction in mean PTSD symptoms. Five RCTs out of 1,552 screened studies were included in this review, all of which showed some level of concern regarding potential bias. Our meta-analysis indicates that I-CBT is equally effective regardless of patients' mean age. Since all RCTs included only provide the mean age of the patients, further randomized controlled trials should address the effectiveness of I-CBT among different age groups.

RESUMO

In 2018, Complex Post Traumatic Stress Disorder (CPTSD) was officially recognized as a distinct syndrome in the International Classification of Diseases, 11th Revision (ICD-11). This recognition aimed to differentiate between neurotic disorders secondary to stressful situations and somatoform disorders, and disorders specifically associated with stress. The inclusion of CPTSD in the ICD-11 marked the culmination of two decades of research focused on understanding its symptoms, treatments, and risk factors. However, despite the progress made, a comprehensive meta-analysis to elucidate the specific risk factors and impact on the development of CPTSD is still lacking. The objective of this article is to conduct such a meta-analysis. A total of 24 studies were selected for analysis, and the findings revealed several key risk factors associated with the development of CPTSD. The main risk factor identified is having experienced sexual abuse in childhood (k = 12; OR = 2.880). In addition, childhood physical abuse (k = 11; OR = 2.841), experiencing emotional neglect during childhood (k = 5; OR = 2.510), physical abuse throughout life (k = 8; OR = 2.149) and being a woman (k = 13; OR = 1.726) were also significant risk factors.

RESUMO

OBJECTIVES: The most recent DSM-5 (2013) and ICD-11 (2018) diagnostic criteria for posttraumatic stress disorder (PTSD) encompass 20 and six symptoms, respectively, organized in different structures. This study aimed to investigate the dimensions of the Posttraumatic Stress Disorder Checklist 5 (PCL-5) according to the DSM-5's broader definition of PTSD and the ICD-11's narrower approach, as well as to explore an alternative restricted model that retains the core symptoms explicitly related to traumatic experiences. METHODS: Data were gathered from Brazilian employees (n=1,101) who had directly experienced traumatic life events or had been exposed to them because of their work activities. Confirmatory factor analysis (CFA) and exploratory structural equation modeling (ESEM) were used to evaluate the configural and metric structures of the models. RESULTS: We estimated seven models of the latent structure of PTSD including the four-factor DSM-5 and three-factor ICD-11 PTSD models. Given the lack of evidence of their validity, an alternative 10-symptom model was tested. The final seven-item PTSD model considerably improved estimation of the PTSD construct. This solution showed reliable items with non-redundant content, acceptable fit indices, and satisfactory configural and metric properties. CONCLUSION: The more parsimonious one-dimensional model comprising the core PTSD symptoms has the potential to improve assessment of PTSD.

RESUMO

Post-traumatic stress (PTSD) disorder is a mental health condition that can occur after experiencing or witnessing a traumatic event. The 27-F earthquake that struck Chile in 2010 was one such event that had a significant impact on the mental health of the population. A study was conducted to investigate the prevalence of PTSD and its associated factors among survivors of this earthquake. The study was a longitudinal design, involving a sample of 913 patients aged 18 to 75 years who attended 10 Primary Care Centers in Concepción, Chile. The Composite International Diagnostic Interview (CIDI) was used to assess both depressive episodes (DE) and PTSD before and after the earthquake. The study also involved genotyping studies using saliva samples from the participants, specifically focusing on the Val66Met and 5-HTTLPR polymorphisms. Statistical analysis was performed to examine the association between different variables and the presence of PTSD. These variables included demographic factors, family history of psychiatric disorders, DE, childhood maltreatment experiences, and critical traumatic events related to the earthquake. The results showed that the incidence of post-earthquake PTSD was 11.06%. No significant differences were found between the groups of participants who developed post-earthquake PTSD regarding the Val66Met or 5-HTTLPR polymorphisms. However, a significant association was found between the concomitant diagnosis of DE and the development of post-earthquake PTSD. The presence of DE doubled the risk of developing post-earthquake PTSD. The number of traumatic events experienced also had a statistically significant association with an increased risk of developing post-earthquake PTSD. The study's limitations include the potential interference of different DE subtypes, the complexity of quantifying the degree of earthquake exposure experienced by each individual, and events entailing social disruption, such as looting, that can profoundly influence distress. In conclusion, the study found that PTSD following the 27-F earthquake in Chile was associated with a concomitant diagnosis of DE and the number of traumatic events experienced. The study did not find a significant association between PTSD and the Val66Met or 5-HTTLPR polymorphisms. The researchers recommend that mental health professionals should prioritize the detection and treatment of concomitant depressive episodes and exposure to critical traumatic events in survivors of disasters. They also suggest that further research is needed to better understand the relationship between genetic factors and post-disaster PTSD.

RESUMO

Sepsis is associated with several comorbidities in survivors, such as posttraumatic stress disorder (PTSD). This study investigated whether rats that survive sepsis develop the generalization of fear memory as a model of PTSD. Responses to interventions that target the endothelin-1 (ET-1)/cannabinoid system and glial activation in the initial stages of sepsis were evaluated. As a control, we evaluated hyperalgesia before fear conditioning. Sepsis was induced by cecal ligation and puncture (CLP) in Wistar rats. CLP-induced sepsis with one or three punctures resulted in fear generalization in the survivors 13 and 20 days after the CLP procedure, a process that was not associated with hyperalgesia. Septic animals were intracerebroventricularly treated with vehicle, the endothelin receptor A (ETA) antagonist BQ123, the cannabinoid CB1 and CB2 receptor antagonists AM251 and AM630, respectively, and the glial blocker minocycline 4 h after CLP. The blockade of either CB1 or ETA receptors increased the survival rate, but only the former reversed fear memory generalization. The endothelinergic system blockade is important for improving survival but not for fear memory. Treatment with the CB2 receptor antagonist or minocycline also reversed the generalization of fear memory but did not increase the survival rate that was associated with CLP. Minocycline treatment also reduced tumor necrosis factor-α levels in the hippocampus suggesting that neuroinflammation is important for the generalization of fear memory induced by CLP. The influence of CLP on the generalization of fear memory was not related to Arc protein expression, a regulator of synaptic plasticity, in the dorsal hippocampus.

RESUMO

Introdução: este artigo apresenta a constituição psíquica e linguística de um jovem autista, proveniente de uma família de imigrantes em situação de pós-guerra, em que entram em questão temas como o luto, a constituição psíquica transgeracional, e a presença de angústias no processo de desenvolvimento da criança em uma situação singular que é a presença do autismo. Objetivo: analisar os efeitos singulares da imigração e multiculturalismo em um caso de autismo e sua evolução terapêutica. Método: estudo de caso longitudinal, que utilizou diário clínico e filmagens de sessões com observações do desenvolvimento de Rafael, desde os dezoito meses até a idade adulta. Como abordagem terapêutica e análise dos resultados, foram utilizados aportes da constituição psíquica da teoria psicanalítica, e sobre o desenvolvimento linguístico em uma perspectiva enunciativa. Resultados: O multiculturalismo acarretava um desafio maior ao processo de aquisição da linguagem por parte da criança com autismo, enquanto o silêncio consequente da dor do luto, presente nos adultos, dificultava a troca verbal e atrasava sua constituição psíquica. O autismo, por sua vez, apresentou-se como transtornos qualitativos na comunicação, necessitando maior investimento por parte de seus cuidadores para que a aquisição da linguagem se desse, pois o paciente precisou ser fisgado para a nossa cultura. Conclusão: Diante de todo esse quadro, o caso clínico demonstra a importância do suporte terapêutico à família e do investimento contínuo na subjetivação, considerando e valorizando os diferentes códigos culturais que compõem o núcleo familiar.

Introduction: this article presents the psychic and linguistic constitution of an autistic young man, from a post-war immigrant family, in which themes such as mourning, the transgenerational psychic constitution, and the presence of anxieties in the process come into question of the child development in a unique situation that is the presence of autism. Objective: to analyze the unique effects of immigration and multiculturalism in a case of autism and its therapeutic evolution. Method: longitudinal case study, which used a clinical diary and footage of sessions with observations of the development of R. from eighteen months to adulthood. As a therapeutic approach and analysis of results, contributions from the psychic constitution of psychoanalytic theory, and on linguistic development in an enunciative perspective, were used. Results: Multiculturalism posed a greater challenge to the process of language acquisition by the child with autism, while the consequent silence of the pain of grief, present in adults, hindered verbal exchange and delayed their psychic constitution. Autism, in turn, presented itself as qualitative disorders in communication, requiring greater investment on the part of its caregivers for the acquisition of language to take place, as it needed to be hooked for our culture. Conclusion: Given this situation, this clinical case demonstrates the importance of therapeutic support to the family and the continuous investment in subjectivity, considering and valuing the different cultural codes that make up the family nucleus.

RESUMO

Delivering electroconvulsive therapy (ECT) during the reconsolidation of traumatic memories may enhance the treatment efficacy in posttraumatic stress disorder (PTSD). To test this, 14 patients with severe and refractory PTSD were randomly allocated to receive ECT sessions either after retrieving the traumatic (n=8) or a neutral (n=6) memory. We found that delivering ECT after retrieving the traumatic memory enhanced the improvement of PTSD symptoms and the reduction of subjective reactivity to the traumatic memory. Reduction in anxiety and mood symptoms and physiological reactivity to the traumatic memory were observed in the sample as a whole regardless of memory retrieval.
