Reconsidering the definition of trauma

Molecular mechanisms and therapeutic possibilities of short-chain fatty acids in posttraumatic stress disorder patients: a mini-review

This mini-review explores the role of short-chain fatty acids (SCFAs) in posttraumatic stress disorder (PTSD). Highlighting the microbiota-gut-brain axis, this study investigated the bidirectional communication between the gut microbiome and mental health. SCFAs, byproducts of gut microbial fermentation, have been examined for their potential impact on PTSD, with a focus on molecular mechanisms and therapeutic interventions. This review discusses changes in SCFA levels and bacterial profiles in individuals with PTSD, emphasizing the need for further research. Promising outcomes from clinical trials using probiotics and fermented formulations suggest potential avenues for PTSD management. Future directions involve establishing comprehensive human cohorts, integrating multiomics data, and employing advanced computational methods, with the goal of deepening our understanding of the role of SCFAs in PTSD and exploring microbiota-targeted interventions.

Challenges of living with veterans with post-traumatic stress disorder from the perspective of spouses: a qualitative content analysis study

BACKGROUND AND OBJECTIVE

The needs and characteristics of veterans with post-traumatic stress disorder (PTSD) create significant challenges in family life, particularly for spouses. Identifying the nature of these challenges from the perspective of spouses leads to a more comprehensive and profound understanding of their existing problems and can be used for targeted interventions. Therefore, this research was conducted to explore the challenges of living with veterans suffering from PTSD from the perspective of their spouses.

METHODS

This qualitative study used conventional content analysis to explore Challenges of spouses of veterans with post-traumatic stress disorder. Fifteen spouses of veterans with PTSD from the Veterans Affairs Center in Iran between June 2022 and January 2023, were purposively selected to participate in the study. Semi-structured in-depth interviews were conducted to collect data. The interviews were audio-recorded and transcribed verbatim. The data were analyzed using the method proposed by Graneheim and Lundman content analysis method with the support of MAXQDA 2020 software.

RESULTS

The mean age of the participants was 56.74 ± 6.43 years. Through data analysis, seven main categories and sixteen subcategories were identified. These categories included burnout (sleep disturbances, feelings of exhaustion), apathy towards self-care and caring for the veteran (neglecting self-care, lack of interest in continuing care), depression (feelings of hopelessness and being at the end of the line, decreased self-confidence ( Crushed and ignored (being mistreated, having multiple roles), relationship disturbances (Dissatisfaction with marital relationship,isolation and limited social interactions, disconnection from God), financial burden (heavy costs of care, lack of insurance support), and declining social status (negative attitude of the society, suffering from discrimination and inequality).

CONCLUSION

The consequences of PTSD-related injuries in veterans directly and indirectly affect the overall living conditions of their spouses. These spouses experience emotional detachment and constant rejection, leading to a decrease in their resilience against existing stressors and exposing them to disruptive and challenging issues in individual, family, and social dimensions of life that affect their physical and mental well-being. Therefore, these spouses require empowerment and access to social support in dimensions of educational, caregiving, therapeutic, and supportive. It is recommended that health policymakers pay special attention to designing up-to-date interventions to enhance the health of these spouses in physical, mental, spiritual, and social dimensions.

Moving From Traumatic Events to Traumatic Experiences in the Study of Traumatic Psychopathology

Trauma is defined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) as an event that includes "actual or threatened death, serious injury, or sexual violence" (p. 271). The list of traumatic events included in the DSM-5 represents a long history of psychiatry and psychology's attempts to define trauma and differentiate these events from less severe stressors. In this commentary, we suggest that this strict distinction between traumatic events and stressful events is not useful for public health. The current DSM-5 list of traumatic events may work well for identifying people with the most severe experiences and highest conditional probability of distress who need clinical care. However, the public health field has different priorities. If we think about posttraumatic psychological distress on a population scale, it is not only helping those with the most severe experiences that is needed; rather, public health requires paying attention to all people experiencing distressing stress and trauma reactions. We propose that context is crucial to the development of a population-relevant definition of trauma and provide examples of situations in which stressors have resulted in posttraumatic psychological distress and in which traumatic event reactions have been mitigated by the context in which they occur. We discuss trauma context from an epidemiologic perspective and conclude with recommendations for the field. This article is part of a Special Collection on Mental Health.

"The trauma machine expands faster than our services": Health risks for unhoused people in an early-stage gentrifying area

While homelessness continues to be a prevalent problem throughout the United States, many urban neighborhoods are also concurrently experiencing an influx of affluent neighbors through gentrification, exposing the stark inequalities in housing access nationwide. Gentrification-induced changes in neighborhood dynamics have also been shown to affect the health of low-income and non-white groups, with high risks of trauma from displacement and exposure to violent crime and criminalization. This study addresses risk factors for health among the most vulnerable, unhoused individuals, and provides a detailed case study on the potential exposures to emotional and physical traumas for unhoused people in early-stage gentrifying areas. By conducting 17 semi-structured interviews with people who work with the unhoused community - health providers, nonprofit employees, neighborhood representatives, and developers - in Kensington, Philadelphia, we analyze how early-stage gentrification impacts the risks for negative health consequences among unhoused groups. Results show that gentrification impacts the health of unhoused people in four main areas that, all together, create what we identify as a "trauma machine" - that is compounding traumas for unhoused residents by 1) reducing and compromising spaces of safety from violent crime, 2) decreasing public services, 3) threatening the quality of healthcare, and 4) increasing the likelihood of displacement and associated trauma.

Advancing health equity by understanding race disparities and other factors associated with PTSD symptom improvement following evidence-based psychotherapy

Several studies found that Black veterans demonstrate less posttraumatic stress disorder (PTSD) symptom improvement than White veterans following PTSD evidence-based psychotherapies (EBPs). We aimed to understand this disparity among veterans receiving EBPs by modeling race with demographic, clinical, and service utilization factors. Using electronic health records, we employed a cohort study of Iraq and Afghanistan War Veterans who initiated PTSD EBP treatment and completed > 2 PTSD symptom measures (N = 21,751). Using hierarchical Bayesian logistic regressions, we modeled the probability of PTSD symptom improvement. Black race was associated with less PTSD improvement (mean posterior odds ratio [MPOR] = 0.92; 95 % plausibility interval [PI] = 0.84, 1.0), as was group therapy (MPOR = 0.67; 95 % PI = 0.62, 0.73). Factors associated with greatest improvement included prolonged exposure (MPOR = 1.35; 95 % PI = 1.25, 1.45) and treatment density (MPOR = 1.40; 95 % PI = 1.36, 1.45). On average, Black veterans evidenced PTSD EBP improvement disparities. Clinical and utilization did not fully account for these disparities, although disproportionate representation of Black veterans in group CPT may explain some of these differences. Understanding experiences such as race-based trauma and chronic racism and discrimination is critical to provide Black veterans with the most effective PTSD care.

Depression and PTSD among Houston Residents who Experienced Hurricane Harvey and COVID-19: Implications for Urban Areas Affected by Multiple Disasters

Little is known about the combined impact of the COVID-19 pandemic and other major disasters on mental health. Hurricane Harvey hit the Gulf Coast in 2017, resulting in substantial costs, significant levels of displacement, and approximately 100 deaths, and was followed in 2020 by the COVID-19 pandemic. We randomly sampled 1167 Houstonians from 88 designated super-neighborhoods and surveyed them about their demographics, event-specific traumas and stressors, and symptoms of current depression and post-traumatic stress disorder (PTSD). We estimated the prevalence of depression (5.8%) and PTSD (12.6%) more than three years after Hurricane Harvey, and assessed the relative influence of event-specific stressors and traumas on current mental health. Overall, we observed evidence for two key findings that are salient for residents of urban environments in the context of multiple disasters. First, stressors were primary influences on depression, whereas both stressors and traumas influenced PTSD. Second, the influences of stressors and traumas on depression and PTSD symptoms faded with time.

Narrative Review of the Complex Interaction between Pain and Trauma in Children: A Focus on Biological Memory, Preclinical Data, and Epigenetic Processes

The incidence and collective impact of early adverse experiences, trauma, and pain continue to increase. This underscores the urgent need for translational efforts between clinical and preclinical research to better understand the underlying mechanisms and develop effective therapeutic approaches. As our understanding of these issues improves from studies in children and adolescents, we can create more precise preclinical models and ultimately translate our findings back to clinical practice. A multidisciplinary approach is essential for addressing the complex and wide-ranging effects of these experiences on individuals and society. This narrative review aims to (1) define pain and trauma experiences in childhood and adolescents, (2) discuss the relationship between pain and trauma, (3) consider the role of biological memory, (4) decipher the relationship between pain and trauma using preclinical data, and (5) examine the role of the environment by introducing the importance of epigenetic processes. The ultimate scope is to better understand the wide-ranging effects of trauma, abuse, and chronic pain on children and adolescents, how they occur, and how to prevent or mitigate their effects and develop effective treatment strategies that address both the underlying causes and the associated physiological and psychological effects.
