Subthreshold post-traumatic stress disorder (PTSD) is more prevalent than PTSD, yet its role as a potential risk factor for PTSD is unknown. To address this gap, we analysed data from a 7-year, prospective national cohort of USA veterans. Of veterans with subthreshold PTSD at wave 1, 34.3% developed PTSD compared with 7.6% of trauma-exposed veterans without subthreshold PTSD (relative risk ratio 6.4). Among veterans with subthreshold PTSD, specific PTSD symptoms, greater age, cognitive difficulties, lower dispositional optimism and new-onset traumas predicted incident PTSD. Results suggest that preventive interventions targeting subthreshold PTSD and associated factors may help mitigate risk for PTSD in USA veterans.

BackgroundSmaller hippocampal volume has often been observed in patients with post-traumatic stress disorder (PTSD). However, there is no consensus whether this is a result of stress/trauma exposure, or constitutes a vulnerability factor for the development of PTSD. Second, it is unclear whether hippocampal volume normalizes with successful treatment of PTSD, or whether a smaller hippocampus is a risk factor for the persistence of PTSD.MethodMagnetic resonance imaging (MRI) scans and clinical interviews were collected from 47 war veterans with PTSD, 25 healthy war veterans (combat controls) and 25 healthy non-military controls. All veterans were scanned a second time with a 6- to 8-month interval, during which PTSD patients received trauma-focused therapy. Based on post-treatment PTSD symptoms, patients were divided into a PTSD group who was in remission (n = 22) and a group in whom PTSD symptoms persisted (n = 22). MRI data were analysed with Freesurfer.ResultsSmaller left hippocampal volume was observed in PTSD patients compared with both control groups. Hippocampal volume of the combat controls did not differ from healthy controls. Second, pre- and post-treatment analyses of the PTSD patients and combat controls revealed reduced (left) hippocampal volume only in the persistent patients at both time points. Importantly, hippocampal volume did not change with treatment.ConclusionsOur findings suggest that a smaller (left) hippocampus is not the result of stress/trauma exposure. Furthermore, hippocampal volume does not increase with successful treatment. Instead, we demonstrate for the first time that a smaller (left) hippocampus constitutes a risk factor for the persistence of PTSD.

Abstract Background Less than half of all individuals with post-traumatic stress disorder (PTSD) remit spontaneously and a large proportion of those seeking treatment do not respond sufficiently. This suggests that there may be subgroups of individuals who are in need of augmentative or alternative treatments. One of the most frequent pathophysiological findings in PTSD is alterations in the hypothalamic–pituitary–adrenal (HPA) axis, including enhanced negative feedback sensitivity and attenuated peripheral cortisol. Given the role of the HPA axis in cognition, this pattern may contribute to PTSD symptoms and interfere with key processes of standard first-line treatments, such as trauma-focused cognitive behavioural therapy (TF-CBT). Methods This review provides a comprehensive summary of the current state of research regarding the role of HPA axis functioning in PTSD symptoms and treatment. Results Overall, there is preliminary evidence that hypocortisolaemia contributes to symptom manifestation in PTSD; that it predicts non-responses to TF-CBT; and that it is subject to change in parallel with positive treatment trajectories. Moreover, there is evidence that genetic and epigenetic alterations within the genes NR3C1 and FKBP5 are associated with this hypocortisolaemic pattern and that some of these alterations change as symptoms improve over the course of treatment. Conclusions Future research priorities include investigations into the role of the HPA axis in day-to-day symptom variation, the time scale in which biological changes in response to treatment occur, and the effects of sex. Furthermore, before conceiving augmentative or alternative treatments that target the described mechanisms, multilevel studies are warranted.

BackgroundPharmacological treatment is widely used for post-traumatic stress disorder (PTSD) despite questions over its efficacy.AimsTo determine the efficacy of all types of pharmacotherapy, as monotherapy, in reducing symptoms of PTSD, and to assess acceptability.MethodA systematic review and meta-analysis of randomised controlled trials was undertaken; 51 studies were included.ResultsSelective serotonin reuptake inhibitors were found to be statistically superior to placebo in reduction of PTSD symptoms but the effect size was small (standardised mean difference −0.23, 95% CI −0.33 to −0.12). For individual pharmacological agents compared with placebo in two or more trials, we found small statistically significant evidence of efficacy for fluoxetine, paroxetine and venlafaxine.ConclusionsSome drugs have a small positive impact on PTSD symptoms and are acceptable. Fluoxetine, paroxetine and venlafaxine may be considered as potential treatments for the disorder. For most drugs there is inadequate evidence regarding efficacy for PTSD, pointing to the need for more research in this area.

"Post-Traumatic Stress Disorder (PTSD) develops after exposure to or witnessing traumatic events. PTSD is very common among the Spinal Cord Injury (SCI) patients. PTSD can be successfully treated with the Cognitive Behavioral Therapy (CBT). However, CBT is mostly used in the western countries, so its efficacy in the eastern culture is still not fully known. Keeping this in view, the current study has determined the efficacy of CBT in the treatment of PTSD among the SCI patients in Pakistan. Using a Randomized Controlled Pilot Study design, data were collected through the Clinician-Administered PTSD Scale for DSM-5 from thirty patients admitted to the Paraplegic Center. Trauma-focused CBT(TF-CBT) protocol was applied through fourteen sessions. Data were analyzed by descriptive and multivariate statistics. Findings show that the level of PTSD symptoms gradually decreased from high at baseline (CAPS-5 Mean Scores μ= 3.6) to low during follow-up stage (CAPS-5 Mean Scores μ= 0.89). Results obtained from the present study on the efficacy of CBT are in concurrence with the research findings in other countries. This study supports the efficiency CBT intervention among Pakistani patients who had developed PTSD symptoms after suffering from SCI. Therefore, CBT can be widely used in the management of PTSD in Pakistan."

Abstract Background Intensive care unit (ICU) staff have faced unprecedented challenges during the coronavirus disease 2019 (COVID-19) pandemic, which could significantly affect their mental health and well-being. The present study aimed to investigate perceived stress and post-traumatic stress disorder (PTSD) symptoms reported by ICU staff working directly with COVID-19 patients. Methods The Perceived Stress Scale was used to assess perceived stress, the PTSD Diagnostic Scale for the Diagnostic and Statistical Manual of Mental Disorders (5th edition) was used to determine PTSD symptoms, and a sociodemographic questionnaire was used to record different sociodemographic variables. Results Altogether, 124 participants (57.2% of whom were men) were included in the analysis. The majority of participants perceived working in the ICU with COVID-19 patients as moderately to severely stressful. Moreover, 71.4% of doctors and 74.4% of nurses experienced moderate-to-severe perceived stress. The staff with previous ICU experience were less likely to have a probable diagnosis of PTSD than those without previous ICU experience. Conclusions Assessing perceived stress levels and PTSD among ICU staff may enhance our understanding of COVID-19-induced mental health challenges. Specific strategies to enhance ICU staff’s mental well-being during the COVID-19 pandemic should be employed and monitored regularly. Interventions aimed at alleviating sources of anxiety in a high-stress environment may reduce the likelihood of developing PTSD.

BackgroundIdentifying risk factors for the development of post-traumatic stress disorder (PTSD) is important for understanding and ultimately preventing the disorder. This study assessed pain shortly after traumatic injury (i.e. peritraumatic pain) as a risk factor for PTSD.MethodParticipants (n=115) were patients admitted to a Level 1 Surgical Trauma Center. Admission to this service reflected a severe physical injury requiring specialized, emergent trauma care. Participants completed a pain questionnaire within 48 h of traumatic injury and a PTSD diagnostic module 4 and 8 months later.ResultsPeritraumatic pain was associated with an increased risk of PTSD, even after controlling for a number of other significant risk factors other than acute stress disorder symptoms. An increase of 0.5 s.d. from the mean in a 0–10 pain rating scale 24–48 h after injury was associated with an increased odds of PTSD at 4 months by more than fivefold, and at 8 months by almost sevenfold. A single item regarding amount of pain at the time of hospital admission correctly classified 65% of participants.ConclusionsIf these findings are replicated in other samples, high levels of peritraumatic pain could be used to identify individuals at elevated risk for PTSD following traumatic injury.

Abstract Post-traumatic stress disorder (PTSD) increases risk of medical comorbidities in aging. The Gerofit Program is an exercise program for older Veterans that shows efficacy for physical health. We sought to determine its impact on PTSD. Veterans in Gerofit completed a self-report questionnaire at 3 and 6 months assessing effect of Gerofit on: PTSD symptoms generally, disturbing dreams, avoidance, negative feelings, and irritability. Two hundred twenty-nine Veterans completed the questionnaire. Of these, 56 (24.5%) reported PTSD. None reported worsened PTSD following Gerofit participation. At 3 months, >50% of Veterans reported symptom improvement and this was maintained over 6 months for all items (p>0.05 paired t-test). There was an increase between 3 and 6 months in the percentage who reported “improved a lot” for overall symptoms (16.7% to 22.2%), negative feelings (5.6% to 11.1%) and irritability (0% to 11.1%). Gerofit may offer an effective intervention to improve PTSD symptoms in older Veterans.

Background Previous research has revealed mixed findings with regard to the effects of disclosure on trauma recovery. More recently, studies on psychological trauma have found associations among religion, meaning, and health. This study investigated prior disclosure as a moderator for the association between religious emotional expression and adaptive trauma processing, as measured by post-traumatic stress disorder (PTSD) symptoms. Methods Using Pennebaker’s written emotional expression paradigm, 105 participants were assigned to either a conventional trauma-writing condition or religious trauma-writing condition. PTSD symptoms were assessed at baseline and again at one-month post writing. Results A two-way interaction was found between prior disclosure and writing condition on PTSD symptoms at follow-up. For the religious trauma-writing condition only, there was a significant difference between low versus high disclosure participants in PTSD symptoms at follow-up, such that low prior disclosure participants registered fewer PTSD symptoms than high prior disclosure participants, while prior disclosure did not have such effect in the conventional trauma-writing condition. Limitations: This two-way interaction may be further qualified by other important psychosocial variables, such as differences in personality, coping style, social support, or use of prayer as a form of disclosure, which were not assessed in this study. Conclusion Religious emotional expression may encourage adaptive trauma processing, especially for individuals with low prior disclosure. These findings encourage further investigation of the conditions under which disclosure and religion may be a beneficial factor in trauma adaptation and treatment.
