PTSD

Black Americans' perceptions of Alzheimer's disease, a healthy brain, and strategies for brain health promotion
Eliacin J, Polsinelli A, Cameron KA, Saykin AJ and Wang S
Lack of awareness of Alzheimer's disease (AD) among Black Americans may undermine their ability to identify potential AD risk. We examined Black Americans' perceptions and knowledge of AD, and views of a healthy brain, which may contribute to the development of effective and culturally sensitive strategies to address racial disparities in AD.
Childhood Maltreatment and Amygdala-Mediated Anxiety and Posttraumatic Stress Following Adult Trauma
Harb F, Liuzzi MT, Huggins AA, Webb EK, Fitzgerald JM, Krukowski JL, deRoon-Cassini TA and Larson CL
Childhood abuse (physical, emotional, and sexual) is associated with aberrant connectivity of the amygdala, a key threat-processing region. Heightened amygdala activity also predicts adult anxiety and posttraumatic stress disorder (PTSD) symptoms, as do experiences of childhood abuse. The current study explored whether amygdala resting-state functional connectivity may explain the relationship between childhood abuse and anxiety and PTSD symptoms following trauma exposure in adults.
Impact of air pollution and climate change on mental health outcomes: an umbrella review of global evidence
Radua J, De Prisco M, Oliva V, Fico G, Vieta E and Fusar-Poli P
The impact of air pollution and climate change on mental health has recently raised strong concerns. However, a comprehensive overview analyzing the existing evidence while addressing relevant biases is lacking. This umbrella review systematically searched the PubMed/Medline, Scopus and PsycINFO databases (up to June 26, 2023) for any systematic review with meta-analysis investigating the association of air pollution or climate change with mental health outcomes. We used the R metaumbrella package to calculate and stratify the credibility of the evidence according to criteria (i.e., convincing, highly suggestive, suggestive, or weak) that address several biases, complemented by sensitivity analyses. We included 32 systematic reviews with meta-analysis that examined 284 individual studies and 237 associations of exposures to air pollution or climate change hazards and mental health outcomes. Most associations (n=195, 82.3%) involved air pollution, while the rest (n=42, 17.7%) regarded climate change hazards (mostly focusing on temperature: n=35, 14.8%). Mental health outcomes in most associations (n=185, 78.1%) involved mental disorders, followed by suicidal behavior (n=29, 12.4%), access to mental health care services (n=9, 3.7%), mental disorders-related symptomatology (n=8, 3.3%), and multiple categories together (n=6, 2.5%). Twelve associations (5.0%) achieved convincing (class I) or highly suggestive (class II) evidence. Regarding exposures to air pollution, there was convincing (class I) evidence for the association between long-term exposure to solvents and a higher incidence of dementia or cognitive impairment (odds ratio, OR=1.139), and highly suggestive (class II) evidence for the association between long-term exposure to some pollutants and higher risk for cognitive disorders (higher incidence of dementia with high vs. low levels of carbon monoxide, CO: OR=1.587; higher incidence of vascular dementia per 1 μg/m increase of nitrogen oxides, NO: hazard ratio, HR=1.004). There was also highly suggestive (class II) evidence for the association between exposure to airborne particulate matter with diameter ≤10 μm (PM) during the second trimester of pregnancy and the incidence of post-partum depression (OR=1.023 per 1 μg/m increase); and for the association between short-term exposure to sulfur dioxide (SO) and schizophrenia relapse (risk ratio, RR=1.005 and 1.004 per 1 μg/m increase, respectively 5 and 7 days after exposure). Regarding climate change hazards, there was highly suggestive (class II) evidence for the association between short-term exposure to increased temperature and suicide- or mental disorders-related mortality (RR=1.024), suicidal behavior (RR=1.012), and hospital access (i.e., hospitalization or emergency department visits) due to suicidal behavior or mental disorders (RR=1.011) or mental disorders only (RR=1.009) (RR values per 1°C increase). There was also highly suggestive (class II) evidence for the association between short-term exposure to increased apparent temperature (i.e., the temperature equivalent perceived by humans) and suicidal behavior (RR=1.01 per 1°C increase). Finally, there was highly suggestive (class II) evidence for the association between the temporal proximity of cyclone exposure and severity of symptoms of post-traumatic stress disorder (r=0.275). Although most of the above associations were small in magnitude, they extend to the entire world population, and are therefore likely to have a substantial impact. This umbrella review classifies and quantifies for the first time the global negative impacts that air pollution and climate change can exert on mental health, identifying evidence-based targets that can inform future research and population health actions.
Absolute and relative outcomes of psychotherapies for eight mental disorders: a systematic review and meta-analysis
Cuijpers P, Miguel C, Ciharova M, Harrer M, Basic D, Cristea IA, de Ponti N, Driessen E, Hamblen J, Larsen SE, Matbouriahi M, Papola D, Pauley D, Plessen CY, Pfund RA, Setkowski K, Schnurr PP, van Ballegooijen W, Wang Y, Riper H, van Straten A, Sijbrandij M, Furukawa TA and Karyotaki E
Psychotherapies are first-line treatments for most mental disorders, but their absolute outcomes (i.e., response and remission rates) are not well studied, despite the relevance of such information for health care users, providers and policy makers. We aimed to examine absolute and relative outcomes of psychotherapies across eight mental disorders: major depressive disorder (MDD), social anxiety disorder, panic disorder, generalized anxiety disorder (GAD), specific phobia, post-traumatic stress disorder (PTSD), obsessive-compulsive disorder (OCD), and borderline personality disorder (BPD). We used a series of living systematic reviews included in the Metapsy initiative (www.metapsy.org), with a common strategy for literature search, inclusion of studies and extraction of data, and a common format for the analyses. Literature search was conducted in major bibliographical databases (PubMed, PsycINFO, Embase, and the Cochrane Register of Controlled Trials) up to January 1, 2023. We included randomized controlled trials comparing psychotherapies for any of the eight mental disorders, established by a diagnostic interview, with a control group (waitlist, care-as-usual, or pill placebo). We conducted random-effects model pairwise meta-analyses. The main outcome was the absolute rate of response (at least 50% symptom reduction between baseline and post-test) in the treatment and control conditions. Secondary outcomes included the relative risk (RR) of response, and the number needed to treat (NNT). Random-effects meta-analyses of the included 441 trials (33,881 patients) indicated modest response rates for psychotherapies: 0.42 (95% CI: 0.39-0.45) for MDD; 0.38 (95% CI: 0.33-0.43) for PTSD; 0.38 (95% CI: 0.30-0.47) for OCD; 0.38 (95% CI: 0.33-0.43) for panic disorder; 0.36 (95% CI: 0.30-0.42) for GAD; 0.32 (95% CI: 0.29-0.37) for social anxiety disorder; 0.32 (95% CI: 0.23-0.42) for specific phobia; and 0.24 (95% CI: 0.15-0.36) for BPD. Most sensitivity analyses broadly supported these findings. The RRs were significant for all disorders, except BPD. Our conclusion is that most psychotherapies for the eight mental disorders are effective compared with control conditions, but absolute response rates are modest. More effective treatments and interventions for those not responding to a first-line treatment are needed.
Psychological outcomes in patients with rare cancers: a systematic review and meta-analysis
Low CE, Loke S, Pang GE, Sim B and Yang VS
Rare cancers are those that exhibit an incidence of less than six per 100,000 in a year. On average, the five-year relative survival for patients with rare cancers is worse than those with common cancers. The traumatic experience of cancer can be further intensified in patients with rare cancers due to the limited clinical evidence and the lack of empirical evidence for informed decision-making. With rare cancers cumulatively accounting for up to 25% of all cancers, coupled with the rising burden of rare cancers on societies globally, it is necessary to determine the psychological outcomes of patients with rare cancers.
Improving Exposure Therapy: Rationale and Design of an International Consortium
Smits JAJ, Abramowitz JS, Arch JJ, Papini S, Anderson RA, Dixon LJ, Graham BM, Hofmann SG, Hoyer J, Huppert JD, Jacquart J, Johnson D, McEvoy PM, McKay D, Newby J, Otto MW, Pittig A, Rief W, Rosenfield D, Timpano KR, Wannemüller A and
The Exposure Therapy Consortium (ETC) was established to advance the science and practice of exposure therapy. To encourage participation from researchers and clinicians, this article describes the organizational structure and activities of the ETC. Initial research working group experiences and a proof-of-principle study underscore the potential of team science and larger-scale collaborative research in this area. Clinical working groups have begun to identify opportunities to enhance access to helpful resources for implementing exposure therapy effectively. This article discusses directions for expanding the consortium's activities and its impact on a global scale.
A Combined Kundalini Yoga and Cognitive Behavioral Therapy Program for Posttraumatic Stress Disorder: A Pilot Study
Staples JK, Mintie D and Khalsa SBS
Cognitive behavioral therapy (CBT) is one of the standard conventional treatments for posttraumatic stress disorder (PTSD). However, recent studies have reported the benefits of yoga for reducing PTSD symptoms including a Kundalini Yoga (KY) intervention. The purpose of this study was to test the efficacy of a novel combined 8-week CBT and KY program for treating PTSD symptoms and improving sleep quality in a single group trial of 26 adults with PTSD. PTSD symptoms (PTSD checklist-5) and sleep quality (Pittsburgh Sleep Quality Index) were assessed at baseline, post intervention, and at 2-month follow-up. Both CBT and yoga homework compliance were also measured. Total PTSD symptom scores as well as the cluster symptoms (intrusion, avoidance, arousal/reactivity, and negative alterations in cognitions and mood) were significantly improved following the program, all < .01. The improvements in total PTSD scores, intrusion, avoidance, arousal/reactivity were maintained at follow-up, with all values still less ( < .01) than baseline. The negative alterations in cognitions and mood symptom cluster continued to improve further at follow-up compared to post-intervention values ( < .05). Total sleep score ( < .05) and the subscales of sleep disturbance ( < .01), daytime dysfunction ( < .05), and sleep quality ( < .01) were significantly improved after the program and these improvements were maintained at follow-up compared to baseline. Sleep medication use was decreased ( < .05) and sleep latency was improved ( < .01) at follow-up only compared to baseline. There was a significant positive correlation ( < .05) between the completion of the yoga home practice and post change in total sleep scores. These results show that a combined KY and CBT intervention resulted in decreased PTSD symptoms and improved sleep quality and suggest this program may constitute an additional treatment option for PTSD.
Exploring decision-making performance in young adults with mental health disorders: a comparative study using the Cambridge gambling task
Effah R, Ioannidis K, Grant JE and Chamberlain SR
Decision-making deficits, assessed cognitively, are often associated with mental health symptoms, however, this relationship is not fully understood. This paper explores the relationship between mental health disorders and decision-making, using the Cambridge Gambling Task (CGT). Our study investigated how decision-making varied across 20 different mental health conditions compared to controls in a sample of 572 young adults from the Minneapolis and Chicago metropolitan areas, using a computerized laboratory-based task. Almost all mental health conditions were associated with at least mild (i.e. at least small effect size) impairment in all three studied parameters of the CGT (risk adjustment, quality of decision-making and overall proportion of bet). Notably, binge eating disorder had the largest cognitive impairment and gambling disorder had moderate impairment. Post-traumatic stress disorder (PTSD) was associated with impaired decision-making while obsessive-compulsive disorder (OCD) and depression showed moderate impairment. Additionally, half of the disorders assessed had moderate to large impairment in risk adjustment.These findings suggest that mental health conditions may have a more complex cognitive profile than previously thought, and a better understanding of these impairments may aid in risk assessment and targeted clinical interventions. This study underscores the need for further research to determine the causal pathways between mental health conditions and cognition, as well as to better understand the day-to-day impact of such deficits.
Parents' knowledge and attitudes towards extracorporeal membrane oxygenation and their post-traumatic stress symptoms
Sun Y, Wang H, Wu Y, Luo L and Shi C
This cross-sectional study, conducted between January 2020 and July 2023, aimed to assess the knowledge, attitude, and post-traumatic stress symptoms (PTSS) among parents with children undergoing extracorporeal membrane oxygenation (ECMO) treatment. Out of 201 valid questionnaires collected, the median knowledge score was 3.00, the mean attitude score was 27.00 ± 3.20, and the mean PTSS score was 3.50 ± 1.54. Logistic regression identified associations between PTSS and parents with lower education levels, particularly junior high school and high school/technical secondary school education, as well as those occupied as housewives. Structural equation modeling highlighted direct effects, such as the impact of residence on education, education on employment status, and associations between knowledge, attitude, PTSS, employment status, monthly income, and parental demographics. The findings indicated inadequate knowledge and suboptimal attitudes among parents, especially those with lower education levels, emphasizing the need for educational resources. Furthermore, addressing parental PTSS through psychosocial support and screening was deemed essential, providing valuable insights for tailored interventions in this context.
[DARJELY, a multidisciplinary support system for young isolated migrants in Lyon]
Plasse A, Lansiaux A, Daras K, Zeroug-Vial H, Icard C and Rolland B
Young, isolated migrants (YIMs) represent some particularly vulnerable populations that have arrived unaccompanied on the national territory and are particularly exposed to mafia networks, delinquency, and prostitution. YIMs thus cumulate social (e.g., precarity, or isolation), psychiatric (e.g., post-traumatic stress disorder, mood, or anxiety disorders), and addiction (e.g., prescription drug dependence) disorders. This addition of vulnerabilities makes the social and medical support difficult to operationalize as it requires multidisciplinary and coordinated programs. In Lyon, the 2nd-largest urban agglomeration in France, the "Dispositif d'accompagnement en Réseau pour l'accès aux soins psychiatriques et addictologiques des jeunes migrants en errance à Lyon" (DARJELY), ("Network System for supporting psychiatric and addiction care to YIMs in Lyon") has been implemented since early 2023 and gathers the following components: (i) a coordinating pair of professionals (i.e., a street worker and an addiction nurse) who ensure a case management of individual situations and articulate the medical and social support with external partners, (ii) an addiction medicine team, (iii) a psychiatric team working at the same place as the addiction medicine team, and (iv) a socio-educational team that can meet YIMs "in situ" and refer them into care, in particular toward teams (ii) and (iii). Overall, DARJELY is thus an innovative system which offers multidisciplinary and coordinated missions toward YIMs including: (i) meeting YIMs on the ground and referring them to specialized care units through the coordination team; (ii) orchestrating the follow-up with other social or medical stakeholders on the local territory; (iii) collecting and synthetizing data for local decision-makers and partners; and (iv) producing research data for improving the understanding of these hard-to-reach populations. All these missions meet current needs of public health regarding these complex populations whose number has been constantly increasing over the recent years.
The central executive network moderates the relationship between posttraumatic stress symptom severity and gastrointestinal related issues
Howard KA, Ahmad SS, Chavez JV, Hoogerwoerd H and McIntosh RC
Although most adults experience at least one traumatic event in their lifetime, a smaller proportion will go on to be clinically diagnosed with post-traumatic stress disorder (PTSD). Persons diagnosed with PTSD have a greater likelihood of developing gastrointestinal (GI) disorders. However, the extent to which subclinical levels of post-traumatic stress (PTS) correspond with the incidence of GI issues in a normative sample is unclear. Resting state fMRI, medical history, psychological survey, and anthropometric data were acquired from the Enhanced Nathan Kline Institute-Rockland Sample (n = 378; age range 18-85.6 years). The primary aim of this study was to test the main effect of subclinical PTS symptom severity on the number of endorsed GI issues. The secondary aim was to test the moderating effect of high versus low resting state functional connectivity (rsFC) of the central executive network (CEN) on the relationship between PTS symptom severity and GI issues. Trauma Symptom Checklist-40 (TSC-40) scores were positively associated with the number of endorsed GI issues (b = -0.038, SE = .009, p < .001). The interaction between TSC-40 scores and rsFC within the CEN was significant on GI issues after controlling for sociodemographic and cardiometabolic variables (b = -0.031, SE = .016, p < .05), such that above average rsFC within the CEN buffered the effect of TSC-40 scores on GI issues. Our findings of higher rsFC within the CEN moderating the magnitude of coincidence in PTS and GI symptom severity may reflect the mitigating role of executive control processes in the putative stress signaling mechanisms that contribute to gut dysbiosis.
Factors associated with posttraumatic stress and anxiety among the parents of babies admitted to neonatal care: a systematic review
Malouf R, Harrison S, Pilkington V, Opondo C, Gale C, Stein A, Franck LS and Alderdice F
Posttraumatic stress (PTS) and anxiety are common mental health problems among parents of babies admitted to a neonatal unit (NNU). This review aimed to identify sociodemographic, pregnancy and birth, and psychological factors associated with PTS and anxiety in this population.
Do childhood experiences influence associations between posttraumatic stress disorder symptoms and positive autobiographical memories among military veteran students? An exploratory study
Miguel-Alvaro A, Messman BA, Weiss NH and Contractor AA
Evidence links posttraumatic stress disorder (PTSD) symptoms and features of positive autobiographical memories (accessibility, vividness, coherence, sharing, emotional intensity, distancing). There is a knowledge gap on how adverse childhood experiences (ACEs) and benevolent childhood experiences (BCEs) may influence these relationships.
Examining the Associations Between Substance Misuse and Suicide Bereavement
Feigelman W, Cerel J, Gutin N, McIntosh JL, Gorman BS, Bottomley JS and Edwards A
Focusing on the understudied question of substance misuse among suicide bereaved adults we investigated patterns of binge drinking and non-prescribed drug use among a recently bereaved sample ( = 1,132). Comparing our respondents to the non-bereaved, those in the 2022 National Survey of Drug Use and Health ( = 71,369), we did not find heightened problematical substance misuses among our respondents. With -tests and multiple regression analyses we examined whether binge drinkers and non-prescribed drug users had heightened levels of grief difficulties, PTSD, self-blaming and depression compared to others not bingeing or using non-prescribed drugs. Results showed binge drinkers had more of all these grieving problems when important confounding variables were also considered. Analysis of the demographic correlates of bingeing showed them dimly aware of their own additional grieving and substance misusing problems. Since 75% indicated being under the care of counseling professionals, this represents an important opportunity for psycho-educational helping.
Three distinct patterns of mental health response following accidents in mountain sports: a follow-up study of individuals treated at a tertiary trauma center
Salvotti HV, Tymoszuk P, Ströhle M, Paal P, Brugger H, Faulhaber M, Kugler N, Beck T, Sperner-Unterweger B and Hüfner K
The restorative effect of physical activity in alpine environments on mental and physical health is well recognized. However, a risk of accidents and post-accident mental health problems is inherent to every sport. We aimed to characterize mental health in individuals following mountain sport accidents requiring professional medical management. Adult victims of mountain sport accidents treated at the hospital of the Medical University of Innsbruck (Austria) between 2018 and 2020 completed a cross-sectional survey at least 6 months following the admission (median 44 months, n = 307). Symptoms of post-traumatic stress disorder (PTSD, PCL-5), anxiety, depression, and somatization (PHQ), resilience (RS-13), sense of coherence (SOC-9L), post-traumatic growth (PTGI), and quality of life (EUROHIS-QOL), as well as sociodemographic and clinical information, were obtained from an online survey and extracted from electronic health records. Mental health outcome patterns were investigated by semi-supervised medoid clustering and modeled by machine learning. Symptoms of PTSD were observed in 19% of participants. Three comparably sized subsets of participants were identified: a (1) neutral, (2) post-traumatic growth, and (3) post-traumatic stress cluster. The post-traumatic stress cluster was characterized by high prevalence of symptoms of mental disorders, low resilience, low sense of coherence, and low quality of life as well as by younger age, the highest frequency of pre-existing mental disorders, and persisting physical health consequences of the accident. Individuals in this cluster self-reported a need for psychological or psychiatric support following the accident and more cautious behavior during mountain sports since the accident. Reliability of machine learning-based prediction of the cluster assignment based on 40 variables available during acute medical treatment of accident victims was limited. A subset of individuals show symptoms of mental health disorders including symptoms of PTSD when assessed at least 6 months after mountain sport accident. Since early identification of these vulnerable patients remains challenging, psychoeducational measures for all patients and low-threshold access to mental health support are key for a successful interdisciplinary management of victims of mountain sport accidents.
High Prevalence of Psychological Comorbidities and Functional Neurological Symptoms in Women With Urinary Retention
Selai C, Lee CH, Simeoni S, Pakzad M, Joyce E, Petrochilos P, Rantell KR, Boico V and Panicker JN
Chronic idiopathic urinary retention (CIUR) in young women is poorly understood and a probable etiology is established only in around 40%, most commonly a primary disorder of external urethral sphincter relaxation, sometimes referred to as Fowler's syndrome. A high prevalence of psychological and functional comorbidities is reported, however these have been poorly characterized.
Which Factors Are Associated With Comorbid Psychiatric Conditions in Patients Affected by Substance Use Disorders? The Impact of COVID-19 Pandemic on Dual-Diagnosis Subjects
Tagliabue I, Caldiroli A, Capuzzi E, Borgonovo R, Scalia A, Ferrè A, Sibilla M, Turco M, Affaticati LM, Crespi G, Galimberti G, Dakanalis A, Colmegna F, Buoli M and Clerici M
To investigate demographic/cinical variables associated to dual diagnosis and the psychological reaction of dual-diagnosis patients to COVID-19 pandemic. Information was collected at the Addiction Service of Monza, Italy. The Impact of Event Scale-Revised (IES-R), a self-report questionnaire measuring the subjective response to a traumatic event, was administered. Univariate analyses and binary logistic regression were performed. IES-R scores were compared between groups defined by qualitative variables through one-way analyses of variance (ANOVA). 118 outpatients were included, 48.3% with dual diagnosis. Alcohol use disorder and being female were associated to dual diagnosis. IES-R scores were significantly higher in the dual-diagnosis group, especially for personality disorders (PDs). IES-R scores were higher in patients taking treatment for substance use disorder (SUD). Females and alcohol abusers were at-risk subjects for dual diagnosis. Patients with SUD and PDs may benefit from additional support, especially when traumatic life events occur. ClinicalTrials.gov Identifier: NCT04694482.
Subtypes of childhood maltreatment and posttraumatic stress disorder symptoms in an adult trauma sample: The mechanistic role of sleep
Harb F, González-Van Wart A, Brzezinski J, deRoon-Cassini TA and Larson CL
Childhood maltreatment is indisputably linked to adverse mental health outcomes, including an increased risk to develop posttraumatic stress disorder (PTSD) in adulthood. The role of childhood maltreatment in the context of recovery from a trauma later in adulthood is not well understood. A variable related to both childhood maltreatment and PTSD symptoms, and a potential link between the two, is sleep. The current study aimed to understand how sleep disturbances may play a mechanistic role in the effect of subtypes of childhood maltreatment on PTSD symptom severity in an adult trauma sample.
Ketamine-enhanced prolonged exposure therapy in veterans with PTSD: A randomized controlled trial protocol
Shiroma PR, Thuras P, Polusny M, Kehle-Forbes S, Disner S, Pardo J, Tolly B, Voller E, McManus E, King C, Lipinski A, Eng E, Hawkinson F and Wang G
The 2023 VA/DoD Clinical Practice Guideline for the Management of PTSD recommends individual, manualized trauma-focused such as Prolonged Exposure (PE) over pharmacologic interventions for the primary treatment of PTSD. Unfortunately, clinical trials of trauma-based therapies in the military and veteran population showed that 30% to 50% of patients did not demonstrate clinically meaningful symptom change. Ketamine, an FDA-approved anesthetic with potent non-competitive glutamatergic N-methyl-d-aspartate antagonistic properties, has demonstrated to enhance the recall of extinction learning and decrease fear renewal without interference of extinction training in preclinical studies.
Exploring the differential effects of psychological resilience and social support in mitigating post-traumatic psychiatric symptoms: real-world network analysis of front-line rescuers
Cheng P, Wang L, Zhou Y, Ma W and Li W
Although both psychological resilience and social support are widely believed to be effective in alleviating post-traumatic psychiatric symptoms in individuals with traumatic events, there has been a lack of comparative analysis of their intervention effects on different post-traumatic psychiatric symptoms. Furthermore, previous studies have mostly failed to control for potential confounding effects caused by different traumatic events.
Eye movement intervention facilitates concurrent perception and memory processing
Wang S, He Y, Hu J, Xia J, Fang K, Yu J and Wang Y
A widely used psychotherapeutic treatment for post-traumatic stress disorder (PTSD) involves performing bilateral eye movement (EM) during trauma memory retrieval. However, how this treatment-described as eye movement desensitization and reprocessing (EMDR)-alleviates trauma-related symptoms is unclear. While conventional theories suggest that bilateral EM interferes with concurrently retrieved trauma memories by taxing the limited working memory resources, here, we propose that bilateral EM actually facilitates information processing. In two EEG experiments, we replicated the bilateral EM procedure of EMDR, having participants engaging in continuous bilateral EM or receiving bilateral sensory stimulation (BS) as a control while retrieving short- or long-term memory. During EM or BS, we presented bystander images or memory cues to probe neural representations of perceptual and memory information. Multivariate pattern analysis of the EEG signals revealed that bilateral EM enhanced neural representations of simultaneously processed perceptual and memory information. This enhancement was accompanied by heightened visual responses and increased neural excitability in the occipital region. Furthermore, bilateral EM increased information transmission from the occipital to the frontoparietal region, indicating facilitated information transition from low-level perceptual representation to high-level memory representation. These findings argue for theories that emphasize information facilitation rather than disruption in the EMDR treatment.
Deep brain stimulation of the amygdala for treatment-resistant combat post-traumatic stress disorder: Long-term results
Koek RJ, Avecillas-Chasin J, Krahl SE, Chen JW, Sultzer DL, Kulick AD, Mandelkern MA, Malpetti M, Gordon HL, Landry HN, Einstein EH and Langevin JP
Deep brain stimulation (DBS) holds promise for neuropsychiatric conditions where imbalance in network activity contributes to symptoms. Treatment-resistant Combat post-traumatic stress disorder (TR-PTSD) is a highly morbid condition and 50% of PTSD sufferers fail to recover despite psychotherapy or pharmacotherapy. Reminder-triggered symptoms may arise from inadequate top-down ventromedial prefrontal cortex (vmPFC) control of amygdala reactivity. Here, we report long-term data on two TR-PTSD participants from an investigation utilizing high-frequency amygdala DBS. The two combat veterans were implanted bilaterally with quadripolar electrodes targeting the basolateral amygdala. Following a randomized staggered onset, patients received stimulation with adjustments based on PTSD symptom severity for four years while psychiatric and neuropsychiatric symptoms, neuropsychological performance, and electroencephalography were systematically monitored. Evaluation of vmPFC-Amygdala network engagement was assessed with FDG positron emission tomography (PET). CAPS-IV scores varied over time, but improved 55% from 119 at baseline to 53 at 4-year study endpoint in participant 1; and 44%, from 68 to 38 in participant 2. Thereafter, during 5 and 1.5 years of subsequent clinical care respectively, long-term bilateral amygdala DBS was associated with additional, clinically significant symptomatic and functional improvement. There were no serious stimulation-related adverse psychiatric, neuropsychiatric, neuropsychological, neurological, or neurosurgical effects. In one subject, symptomatic improvement was associated with an intensity-dependent reduction in amygdala theta frequency power. In our two participants, FDG-PET findings were inconclusive regarding the hypothesized mechanism of suppression of amygdala hyperactivity. Our findings encourage further research to confirm and extend our preliminary observations.
Mendelian randomization analyses reveal causal relationships between brain functional networks and risk of psychiatric disorders
Mu C, Dang X and Luo XJ
Dysfunction of brain resting-state functional networks has been widely reported in psychiatric disorders. However, the causal relationships between brain resting-state functional networks and psychiatric disorders remain largely unclear. Here we perform bidirectional two-sample Mendelian randomization (MR) analyses to investigate the causalities between 191 resting-state functional magnetic resonance imaging (rsfMRI) phenotypes (n = 34,691 individuals) and 12 psychiatric disorders (n = 14,307 to 698,672 individuals). Forward MR identified 8 rsfMRI phenotypes causally associated with the risk of psychiatric disorders. For example, the increase in the connectivity of motor, subcortical-cerebellum and limbic network was associated with lower risk of autism spectrum disorder. In adddition, increased connectivity in the default mode and central executive network was associated with lower risk of post-traumatic stress disorder and depression. Reverse MR analysis revealed significant associations between 4 psychiatric disorders and 6 rsfMRI phenotypes. For instance, the risk of attention-deficit/hyperactivity disorder increases the connectivity of the attention, salience, motor and subcortical-cerebellum network. The risk of schizophrenia mainly increases the connectivity of the default mode and central executive network and decreases the connectivity of the attention network. In summary, our findings reveal causal relationships between brain functional networks and psychiatric disorders, providing important interventional and therapeutic targets for psychiatric disorders at the brain functional network level.
Intensive longitudinal assessment following index trauma to predict development of PTSD using machine learning
Horwitz A, McCarthy K, House SL, Beaudoin FL, An X, Neylan TC, Clifford GD, Linnstaedt SD, Germine LT, Rauch SL, Haran JP, Storrow AB, Lewandowski C, Musey PI, Hendry PL, Sheikh S, Jones CW, Punches BE, Swor RA, Hudak LA, Pascual JL, Seamon MJ, Harris E, Pearson C, Peak DA, Domeier RM, Rathlev NK, Sergot P, Sanchez LD, Bruce SE, Joormann J, Harte SE, Koenen KC, McLean SA and Sen S
There are significant challenges to identifying which individuals require intervention following exposure to trauma, and a need for strategies to identify and provide individuals at risk for developing PTSD with timely interventions. The present study seeks to identify a minimal set of trauma-related symptoms, assessed during the weeks following traumatic exposure, that can accurately predict PTSD. Participants were 2185 adults (Mean age=36.4 years; 64% women; 50% Black) presenting for emergency care following traumatic exposure. Participants received a 'flash survey' with 6-8 varying symptoms (from a pool of 26 trauma symptoms) several times per week for eight weeks following the trauma exposure (each symptom assessed ∼6 times). Features (mean, sd, last, worst, peak-end scores) from the repeatedly assessed symptoms were included as candidate variables in a CART machine learning analysis to develop a pragmatic predictive algorithm. PTSD (PCL-5 ≥38) was present for 669 (31%) participants at the 8-week follow-up. A classification tree with three splits, based on mean scores of nervousness, rehashing, and fatigue, predicted PTSD with an Area Under the Curve of 0.836. Findings suggest feasibility for a 3-item assessment protocol, delivered once per week, following traumatic exposure to assess and potentially facilitate follow-up care for those at risk.
The application of machine learning techniques in posttraumatic stress disorder: a systematic review and meta-analysis
Wang J, Ouyang H, Jiao R, Cheng S, Zhang H, Shang Z, Jia Y, Yan W, Wu L and Liu W
Posttraumatic stress disorder (PTSD) recently becomes one of the most important mental health concerns. However, no previous study has comprehensively reviewed the application of big data and machine learning (ML) techniques in PTSD. We found 873 studies meet the inclusion criteria and a total of 31 of those in a sample of 210,001 were included in quantitative analysis. ML algorithms were able to discriminate PTSD with an overall accuracy of 0.89. Pooled estimates of classification accuracy from multi-dimensional data (0.96) are higher than single data types (0.86 to 0.90). ML techniques can effectively classify PTSD and models using multi-dimensional data perform better than those using single data types. While selecting optimal combinations of data types and ML algorithms to be clinically applied at the individual level still remains a big challenge, these findings provide insights into the classification, identification, diagnosis and treatment of PTSD.
The role of SKA2 on affective disorder, post-traumatic stress disorder and suicide behavior: systematic review and in silico analysis

Genes involved in the hypothalamic-pituitary-adrenal axis may be a robust biomarker of psychiatric disorders. Genetic polymorphisms of the SKA2 gene are associated with several behavioral disorders. In this study, we embarked on a systematic search of all possible reports of genetic association with SKA2 and affective disorder, post-traumatic stress disorder, and suicide behavior; the functional consequences of nsSNPs were explored through computational tools with an in silico analysis. Eight eligible articles were included. Our study identified that SKA2 did not show association with risk of Major Depression Disorder. Epigenetic variation at SKA2 mediates vulnerability to Post-Traumatic Stress Disorder. Studies provide strong preliminary evidence that alterations at the SKA2 gene covary with types of suicide behavior, including suicidal ideation, attempts, and completions. Results from in silico analysis predicted that I22S, I22G, I78T, A15L, D18R, R25L, N42I, Y21S, K14I, K14L, and L60R were the most structurally and functionally significant nsSNPs in SKA2. Amino acid conservation analysis revealed that the amino acids were highly conserved and some dissimilarities of mutant type amino acids from wild-type amino acids such as charge, size, and hydrophobicity were observed. In the future, SKA2 gene have the potential to be evaluated as prognostic biomarkers for diagnosis and research.
Health impacts of war: case studies of New Zealand veterans of the First World War
Wilson N, Summers JA, Clement C and Thomson G
Armed conflict remains a tragic feature of the modern world and so it is necessary to continue to study its health impacts. Even the study of historical conflicts is relevant given that certain health impacts are common to most wars e.g., post-traumatic stress disorder (PTSD).
Properties of the modified self-forgiveness dual-process scale in populations at risk for moral injury
Griffin BJ, Norman SB, Weber MC, Hinkson KD, Jendro AM, Pyne JM, Worthington EL and Maguen S
Despite theory suggesting that self-forgiveness facilitates recovery from moral injury, no measure of self-forgiveness has been validated with individuals exposed to potentially morally injurious events (PMIEs). Military veterans, healthcare workers, and first responders who reported PMIE exposure (n = 924) completed the Self-Forgiveness Dual-Process Scale, which assesses two dimensions of the self-forgiveness process. The first dimension, value affirmation, refers to appraising personal responsibility and being willing to make amends for one's involvement in a PMIE. The second dimension, esteem restoration, refers to accepting oneself as valuable and capable of growth despite one's failures and imperfections. Exploratory and Confirmatory Factor Analyses replicated the original scale's two-factor structure in 10 items modified to apply to the diverse contexts in which PMIEs occur. Next, we found that the factor structure, item loadings, and item intercepts were fully or partially invariant across professions, genders, races, ages, and religious affiliations in a series of Multi-Group Confirmatory Factor Analyses. Finally, diverging patterns of associations between value affirmation and esteem restoration with moral distress, posttraumatic stress, depression, insomnia, functional impairment, and posttraumatic growth provide evidence of convergent and discriminant validity between the subscales. The modified self-forgiveness dual process scale is the first measure of self-forgiveness to be validated with individuals exposed to a PMIE. Researchers and clinicians can use the scale to examine how self-forgiveness (or difficulties with forgiving oneself) relates to moral injury.
Prospective Bidirectional Relationship Between Sleep Duration and Posttraumatic Stress Disorder Symptoms After Suspected Acute Coronary Syndrome
Cornelius T, Edmondson D, Abdalla M, Scott A, Fernandez Sedano B, Hiti D, Sullivan AM, Schwartz JE, Kronish IM and Shechter A
Sleep disturbance is a "hallmark" symptom of posttraumatic stress disorder (PTSD). Poor sleep (including short sleep) after combat-related trauma can also predict subsequent PTSD. Less is known about the association between sleep duration and PTSD symptoms when PTSD is induced by acute coronary syndrome (ACS). We examined the bidirectional relationship between sleep duration and PTSD symptoms over the year after hospital evaluation for ACS.

Peer support during in vivo exposure homework increases likelihood of prolonged exposure therapy completion
Hernandez-Tejada MA, Bruce MJ, Muzzy W, Birks A, Macedo E Cordeiro G, Hart SM, Hamski S and Acierno R
Exposure-based treatments such as prolonged exposure therapy (PE) are effective for veterans with PTSD. However, dropout rates as high as 50% are common. The Department of Veterans Affairs employs peers to increase mental health treatment engagement, however peers are not routinely used to help patients complete PE homework assignments. The present study included 109 veterans who decided to drop out from exposure-based treatment after completing seven or fewer sessions and used a randomized controlled design to compare PE treatment completion rates in response to 2 forms of peer support: (1) standard weekly telephone-based peer support vs. (2) peer-assisted in vivo exposure, wherein peers accompanied veterans (virtually or in person) during a limited number of in vivo exposure assignments. There were no differences between instrumental vs general peer support conditions as randomized. However, post hoc analyses indicated that 87% of those who completed at least one peer-assisted in vivo exposure completed treatment, compared to 56% of those not completing any peer-assisted in vivo exposure. The dose effect of peer-assisted in vivo exposure increased to 93% with 2 or more peer-assisted exposures, and 97% with 3 or more peer-assisted exposures. The present study suggests that augmenting PE with instrumental peer support during in vivo exposure homework may reduce dropout if completed. Future research should test whether the impact of peer-assisted in vivo exposure is enhanced when offered at the beginning of treatment as opposed to waiting until the point of dropout.
What is needed for the roll-out of psychedelic treatments?

A Scoping Review of Suicide Prevention Interventions for Lesbian, Gay, Bisexual, Transgender, Queer, and Other Sexual and Gender Minority Individuals
Chang CJ, Livingston NA, Rashkovsky KT, Harper KL, Kuehn KS, Khalifian C, Harned MS, Tucker RP and Depp CA
This scoping review summarizes the literature on suicide-specific psychological interventions among lesbian, gay, bisexual, transgender, queer, and other sexual and gender minority (LGBTQ+) people to synthesize existing findings and support future intervention research and dissemination. Electronic databases PsycInfo and PubMed were searched for reports of psychological intervention studies with suicide-related outcome data among LGBTQ+ people. A total of 1269 articles were screened, and 19 studies met inclusion criteria ( = 3 examined suicide-specific interventions tailored to LGBTQ+ people,  = 4 examined nontailored suicide-specific interventions,  = 11 examined minority stress- or LGBTQ+ interventions that were not suicide-specific, and  = 1 examined other types of interventions). Synthesis of this literature was made challenging by varied study designs, and features limit confidence in the degree of internal and external validity of the interventions evaluated. The only established suicide-specific intervention examined was Dialectical Behavior Therapy, and minority stress- and LGBTQ-specific interventions rarely targeted suicidal thoughts and behaviors (STBs). Nevertheless, most interventions reviewed demonstrated support for feasibility and/or acceptability. Only five studies tested suicide-related outcome differences between an LGBTQ+ group and a cisgender/heterosexual group. These studies did not find significant differences in STBs, but certain subgroups such as bisexual individuals may exhibit specific treatment disparities. Given the dearth of research, more research examining interventions that may reduce STBs among LGBTQ+ people is critically needed to address this public health issue.
Using brief reflections to capture and evaluate end-user engagement: a case example using the COMPASS study
Ackland PE, Hagedorn HJ, Kenny ME, Salameh HA, Kehle-Forbes SM, Gustavson AM, Karimzadeh LE and Meis LA
Use of participatory research methods is increasing in research trials. Once partnerships are established with end-users, there is less guidance about processes research teams can use to successfully incorporate end-user feedback. The current study describes the use of a brief reflections process to systematically examine and evaluate the impact of end-user feedback on study conduct.

Salivary inflammatory biomarkers as a predictor of post-traumatic stress disorder and depressive symptom severity in trauma patients: A prospective study
Robles TF, Rünger D, Sumner JA, Elashoff D and Shetty V
Although post-traumatic stress disorder (PTSD) and depression screening are recommended for traumatic injury patients, routine screening is still uncommon. Salivary inflammatory biomarkers have biological plausibility and potential feasibility and acceptability for screening. This study tested prospective associations between several salivary inflammatory biomarkers (proinflammatory cytokines interleukin-1β, interleukin-6, tumor necrosis factor-α; and C-reactive protein), collected during hospitalization and PTSD and depressive symptoms at 5-month follow-up.

Using machine learning to increase access to and engagement with trauma-focused interventions for posttraumatic stress disorder
Lenton-Brym AP, Collins A, Lane J, Busso C, Ouyang J, Fitzpatrick S, Kuo JR and Monson CM
Post-traumatic stress disorder (PTSD) poses a global public health challenge. Evidence-based psychotherapies (EBPs) for PTSD reduce symptoms and improve functioning (Forbes et al., Guilford Press, 2020, 3). However, a number of barriers to access and engagement with these interventions prevail. As a result, the use of EBPs in community settings remains disappointingly low (Charney et al., Psychological Trauma: Theory, Research, Practice, and Policy, 11, 2019, 793; Richards et al., Community Mental Health Journal, 53, 2017, 215), and not all patients who receive an EBP for PTSD benefit optimally (Asmundson et al., Cognitive Behaviour Therapy, 48, 2019, 1). Advancements in artificial intelligence (AI) have introduced new possibilities for increasinfg access to and quality of mental health interventions.

The role of nitric oxide and hormone signaling in chronic stress, anxiety, depression and post traumatic stress disorder
Jankovic T, Bogicevic M and Knezevic NN
This paper provides a summary of the role of nitric oxide (NO) and hormones in the development of chronic stress, anxiety, depression, and post-traumatic stress disorder (PTSD). These mental health conditions are prevalent globally and involve complex molecular interactions. Although there is a significant amount of research and therapeutic options available, the underlying mechanisms of these disorders are still not fully understood. The primary pathophysiologic processes involved in chronic stress, anxiety, depression, and PTSD include dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, the intracellular influence of neuronal nitric oxide synthase (nNOS) on transcription factors, an inflammatory response with the formation of nitrergic oxidative species, and reduced serotonergic transmission in the dorsal raphe nucleus. Despite the extensive literature on this topic, there is a great need for further research to clarify the complexities inherent in these pathways, with the primary aim of improving psychiatric care.

Posttraumatic stress disorder is characterized by functional dysregulation of dermal fibroblasts
van de Vyver M, Benecke RM, van den Heuvel L, Kruger MJ, Powrie Y, Seedat S and Smith C
Incidence of mental health disorders are rising in modernity, with psychological stress linked to a propensity for developing various chronic diseases due to a relative inability of the body to counter the allostatic load on cellular level. Despite these high rates of comorbidities associated with posttraumatic stress disorder (PTSD), there is still a lack of understanding in terms of the peripheral effects of PTSD on tissue level. Therefore, the purpose of this study was to profile basal dermal fibroblast functional status in PTSD using a wide range of markers involved in the cell-to-cell communication facilitated by fibroblasts. Primary dermal fibroblasts derived from patients diagnosed with PTSD (n = 11) and matched trauma exposed controls (i.e. who did not develop PTSD, n = 10) were cultured using standard techniques. The patients and controls were matched based on age, sex, body-mass index (BMI) and lifestyle. The growth rate, population doubling time, surface marker expression (CD31, FNDC5) (flow cytometry), secretome (TIMP-2, MMP-9) (ELISAs), intracellular signalling capacity (Fluo-4 Ca flux) and gene expression (IL-6, IL-10, PTX-3, iNOS, Arg1) were compared between groups. The data illustrated significant PTSD-associated fibroblast conditioning resulting in a blunted signalling capacity. This observation highlights the importance of including tissue-specific investigations in future studies focused on elucidating the association between PTSD and subsequent risk for somatic disease.
Spatiotemporal organization of prefrontal norepinephrine influences neuronal activity
Glaeser-Khan S, Savalia NK, Cressy J, Feng J, Li Y, Kwan AC and Kaye AP
Norepinephrine (NE), a neuromodulator released by locus coeruleus (LC) neurons throughout cortex, influences arousal and learning through extra-synaptic vesicle exocytosis. While NE within cortical regions has been viewed as a homogenous field, recent studies have demonstrated heterogeneous axonal dynamics and advances in GPCR-based fluorescent sensors permit direct observation of the local dynamics of NE at cellular scale. To investigate how the spatiotemporal dynamics of NE release in the prefrontal cortex (PFC) affect neuronal firing, we employed in vivo two-photon imaging of layer 2/3 of PFC in order to observe fine-scale neuronal calcium and NE dynamics concurrently. In this proof of principle study, we found that local and global NE fields can decouple from one another, providing a substrate for local NE spatiotemporal activity patterns. Optic flow analysis revealed putative release and reuptake events which can occur at the same location, albeit at different times, indicating the potential to create a heterogeneous NE field. Utilizing generalized linear models, we demonstrated that cellular Ca fluctuations are influenced by both the local and global NE field. However, during periods of local/global NE field decoupling, the local field drives cell firing dynamics rather than the global field. These findings underscore the significance of localized, phasic NE fluctuations for structuring cell firing, which may provide local neuromodulatory control of cortical activity. NE is a neuromodulator which plays a critical role in learning and arousal, but understanding its spatial scale has been limited by technical barriers. Here, we utilized two-photon imaging of GPCR-based sensors, light sheet imaging, and computational modeling to gain insight into the fine scale organization of NE in PFC. We found that NE can influence neuronal activity at a local scale within cortex, which has not been shown before, and we developed new computational approaches to analyzing two-photon imaging of GPCR based fluorescent sensors. This insight will facilitate improved understanding of NE's role in motivated behaviors, as well as new approaches for understanding local neurotransmitter function.
Neurogenesis-dependent remodeling of hippocampal circuits reduces PTSD-like behaviors in adult mice
Fujikawa R, Ramsaran AI, Guskjolen A, de la Parra J, Zou Y, Mocle AJ, Josselyn SA and Frankland PW
Post-traumatic stress disorder (PTSD) is a hypermnesic condition that develops in a subset of individuals following exposure to severe trauma. PTSD symptoms are debilitating, and include increased anxiety, abnormal threat generalization, and impaired extinction. In developing treatment strategies for PTSD, preclinical studies in rodents have largely focused on interventions that target post-encoding memory processes such as reconsolidation and extinction. Instead, here we focus on forgetting, another post-encoding process that regulates memory expression. Using a double trauma murine model for PTSD, we asked whether promoting neurogenesis-mediated forgetting can weaken trauma memories and associated PTSD-relevant behavioral phenotypes. In the double trauma paradigm, consecutive aversive experiences lead to a constellation of behavioral phenotypes associated with PTSD including increases in anxiety-like behavior, abnormal threat generalization, and deficient extinction. We found that post-training interventions that elevate hippocampal neurogenesis weakened the original trauma memory and decreased these PTSD-relevant phenotypes. These effects were observed using multiple methods to manipulate hippocampal neurogenesis, including interventions restricted to neural progenitor cells that selectively promoted integration of adult-generated granule cells into hippocampal circuits. The same interventions also weakened cocaine place preference memories, suggesting that promoting hippocampal neurogenesis may represent a broadly useful approach in hypermnesic conditions such as PTSD and substance abuse disorders.
Beyond surviving: A scoping review of collaborative care models to inform the future of post-discharge trauma care
Ilkhani S, Comrie CE, Pinkes N, Zier CL, Gaudino SG, Slavin MD, Kazis LE, Ryan CM, Schneider JC, Livingston DH, Salim A, Anderson GA and Herrera-Escobar JP
Trauma centers demonstrate an impressive ability to save lives, as reflected by inpatient survival rates of over 95% in the United States. Nevertheless, we fail to allocate sufficient effort and resources to ensure that survivors and their families receive the necessary care and support after leaving the trauma center. The objective of this scoping review is to systematically map the research on collaborative care models (CCM) that have been put forward to improve trauma survivorship. Of 833 articles screened, we included 16 studies evaluating eight collaborative care programs, predominantly in the U.S. The majority of the programs offered care coordination and averaged 9-months in duration. Three-fourths of the programs incorporated a mental health provider within their primary team. Observed outcomes were diverse: some models showed increased engagement (e.g., Center for Trauma Survivorship, trauma quality-of-life follow-up clinic), while others presented mixed mental health outcomes and varied results on pain and healthcare utilization. The findings of this study indicate that collaborative interventions may be effective in mental health screening, PTSD and depression management, effective referrals, and improving patient satisfaction with care. A consensus on core elements and cost-effectiveness of CCMs is necessary to set the standard for comprehensive care in post-trauma recovery.
Efficacy of two brief trauma-focussed writing interventions in comparison to positive experiences writing: A randomized controlled trial
Dawson RL, Nixon RDV, Calear AL, Sivanathan D and O'Kearney R
There is emerging literature regarding the efficacy of trauma-focussed writing therapies (TF-WTs) for posttraumatic stress. Such therapies have the potential to reduce posttraumatic stress symptoms (PTSS) in a brief time frame and can be delivered remotely. There remains a need for further research assessing the efficacy of different types of TF-WTs, as well comparing them to alternative control conditions not previously assessed. The present study assessed two TF-WTs that had differing writing instructions in comparison to an intervention that involved writing about positive experiences.
Stress Exposure and PTSD in a Cross-Sectional Residential Substance Use Treatment Sample
Schacht RL, Meyer LE, Wenzel KR, Mette ME, Berg SK, Lewis CR, Carrano JL and Fishman M
Aim 1 of this cross-sectional, observational study with people in residential treatment for substance use disorders (SUDs) was to document stress exposure. Aim 2 was to assess potential sociodemographic and health differences based on probable posttraumatic stress disorder (PTSD) status. Aim 3 was to assess relative contributions of Diagnostic and Statistical Manual (DSM)-congruent versus DSM-incongruent stressors (Criterion A vs non-Criterion A) to mental and physical health. We hypothesized that both types of stressors would significantly contribute to impairment across indicators and that DSM-congruent stressor exposure would be more strongly associated with impairment than DSM-incongruent exposure.
Psychiatric comorbidity and severity in anorexia nervosa: a comparative study of the DSM-5, the ICD-11, and overvaluation of Weight/Shape severity ratings
Dang AB, Kiropoulos L, Castle D, Jenkins Z, Phillipou A, Rossell S and Krug I
This study assessed the rate of a.) the total and b.) specific psychiatric comorbidities among the three severity ratings for Anorexia Nervosa (AN): DSM-5, ICD-11 and overvaluation of weight and shape (OWS). The sample comprised 312 treatment-seeking patients with AN (mean age = 26.9). Weight and height were taken at intake to calculate BMI, the foundation for the DSM-5 and ICD-11 severity indices. The EDE-Q was used to assess OWS, and the Mini International Neuropsychiatric Interview was conducted to assess psychiatric comorbidities. For the DSM-5, the mild severity group showed a higher total number of psychiatric comorbidities, especially for panic, social anxiety, generalised anxiety, and post-traumatic stress disorders compared to the severe and extremely severe groups. ICD-11 and OWS severity groups did not significantly differ in total comorbidities, except for major depressive disorder and obsessive-compulsive disorders being more prevalent in the "significantly low BMI" ICD-11 group. The high OWS group displayed a notably higher rate of major depressive disorder than the low OWS group. The study underscores inconsistent patterns across the three severity systems, emphasising the need to recognise the current limitations of the assessed severity classification systems in AN assessment and guiding treatment.
Trauma exposure across the lifespan among individuals engaged in treatment with medication for opioid use disorder: differences by gender, PTSD status, and chronic pain
Rodríguez MN, Colgan DD, Leyde S, Pike K, Merrill JO and Price CJ

[MDMA-assisted therapy for PTSD]
Thorarinsdottir H, Gudmundsdottir B and Sigurdsson E
MDMA is a potential novel treatment for post-traumatic stress disorder (PTSD). Our goal is to review current knowledge on MDMA and its use in MDMA-assisted psychotherapy for PTSD. Literature searches were done on PubMed, Web of Science and Google Scholar and references reviewed in identified articles. MDMA-assisted therapy for PTSD usually consists of a few preparatory sessions before two or three sessions where one or two oral doses of MDMA are given along with supportive psychotherapy. The therapy is delivered in the presence of two therapists for about eight hours each time. In addition, the patient receives up to 9 integrative sessions in due course. This use of MDMA as a part of psychotherapy for PTSD is proposed to lessen the psychological distress that often arises in the processing of traumatic events to facilitate the treatment process and reduce the risk of drop-out. Recent studies indicate that MDMA-assisted psychotherapy reduces PTSD symptoms and is generally well tolerated. These studies are necessary if this MDMA-assisted treatment is to be approved by licensing authorities. There is an urgent need for new effective treatments for PTSD and for comparisons between this MDMA-assisted psychotherapy and currently approved psychotherapies with and without MDMA-use.
Paeoniflorin exerts anti-PTSD effects in adult rats by modulating hippocampus and amygdala histone acetylation modifications in response to early life stress
Xu H, Zhang T, Li L, Qu Y, Li L, Yan Y, Wu L and Yan C
Early life stress (ELS) can cause long-term changes by epigenetic factors, especially histone acetylation modification, playing a crucial role, affect normal cognition, mood, and behavior, and increase susceptibility to post-traumatic stress disorder (PTSD) in adulthood. It has been found that paeoniflorin (PF) can cross the blood-brain barrier to exert anti-PTSD effects on adult PTSD rats. However, whether PF can alleviate the harmful effects caused by ELS in adulthood has not yet been reported. Therefore, to explore the relationship between ELS and PTSD susceptibility in adulthood and its mechanism, in this study, SPS was used as a stressor of ELS, and the mathematical tool Z-normalization was employed as an evaluation criterion of behavioral resilience susceptibility. To investigate the regulatory mechanism of PF on histone acetylation in the hippocampus and amygdala of ELS rats in adulthood, using changes in HATs/HDACs as the entry point, meanwhile, the epigenetic marks (H3K9 and H4K12) in the key brain regions of ELS (hippocampus and amygdala) were evaluated, and the effects of PF on behavioral representation and PTSD susceptibility were observed. This study found that ELS lead to a series of PTSD-like behaviors in adulthood and caused imbalance of HATs/HDACs ratio in the hippocampus and amygdala, which confirms that ELS is an important risk factor for the development of PTSD in adulthood. In addition, paeoniflorin may improve ELS-induced PTSD-like behaviors and reduce the susceptibility of ELS rats to develop PTSD in adulthood by modulating the HATs/HDACs ratio in the hippocampus and amygdala.
Nationwide Assessment of Chronic Pain among Hospitalized Individuals with Co-occurring Post Traumatic Stress Disorder and Substance Use Disorder in the United States
Olayinka O, Alemu BT, Nkemjika S and Barry DT
Chronic pain (CP) is independently associated with substance use disorders (SUD) and posttraumatic stress disorder (PTSD). However, little is known about factors associated with CP among patients with co-occurring PTSD and SUD. Patterns of hospital resource usage should also be explored further. Using the 2019 National Inpatient Sample (NIS), we identified 216,125 hospital discharges with co-occurring diagnoses of PTSD and SUD in 2019 and examined their association with CP. Multivariable logistic regression models were used to identify factors associated with an increased likelihood of CP in this cohort. Among those with co-occurring PTSD and SUD ( = 216,125), 35,450 had associated CP, a prevalence of 164.02 cases per 1,000 discharges (95% CI [160.54, 167.52]). Individuals aged 55-64 with co-occurring PTSD and SUD were approximately 7.2 times more likely to experience CP, compared to those aged 16-24 (OR = 7.2; 95% CI [6.09, 8.60]). Being in the CP group was associated with 50% increased odds of insomnia and obesity (OR = 1.5; 95% CI [1.12, 2.03] and OR = 1.5; 95% CI [1.38, 1.55], respectively), 30% increased odds of anxiety (OR = 1.3; 95% CI [1.24, 1.38]), 20% increased odds of attention deficit disorder (ADD;OR = 1.2; 95% CI [1.12, 1.38]) and 10% increased odds of depression (OR = 1.1; 95% CI [1.01, 1.14]). Compared with females, being male was associated with slightly decreased odds of CP (OR = 0.9; 95% CI [0.84, 0.94]). Among hospitalized Americans with co-occurring PTSD and SUD, advanced age, being female, and the presence other mental health disorders were associated with an increased risk of CP. Providers treating co-occurring PTSD/SUD should evaluate for and consider evidence-based management of CP if present.
Acute Stress Effects on Statistical Learning and Episodic Memory
Sherman BE, Huang I, Wijaya EG, Turk-Browne NB and Goldfarb EV
Stress is widely considered to negatively impact hippocampal function, thus impairing episodic memory. However, the hippocampus is not merely the seat of episodic memory. Rather, it also (via distinct circuitry) supports statistical learning. On the basis of rodent work suggesting that stress may impair the hippocampal pathway involved in episodic memory while sparing or enhancing the pathway involved in statistical learning, we developed a behavioral experiment to investigate the effects of acute stress on both episodic memory and statistical learning in humans. Participants were randomly assigned to one of three conditions: stress (socially evaluated cold pressor) immediately before learning, stress ∼15 min before learning, or no stress. In the learning task, participants viewed a series of trial-unique scenes (allowing for episodic encoding of each image) in which certain scene categories reliably followed one another (allowing for statistical learning of associations between paired categories). Memory was assessed 24 hr later to isolate stress effects on encoding/learning rather than retrieval. We found modest support for our hypothesis that acute stress can amplify statistical learning: Only participants stressed ∼15 min in advance exhibited reliable evidence of learning across multiple measures. Furthermore, stress-induced cortisol levels predicted statistical learning retention 24 hr later. In contrast, episodic memory did not differ by stress condition, although we did find preliminary evidence that acute stress promoted memory for statistically predictable information and attenuated competition between statistical and episodic encoding. Together, these findings provide initial insights into how stress may differentially modulate learning processes within the hippocampus.
Exploring heterogeneity in PTSD symptoms and associated predictors and outcomes in Afghanistan veterans: A latent profile analysis
Rønning L, Anyan F, Hjemdal O, Bøe HJ, Espetvedt Nordstrand A, Herberman Mash HB and Naifeh JA
Research on posttraumatic stress symptoms (PTSS) typically focuses on diagnosis or symptom severity, however, this overlooks the variety of symptom patterns that exist. Latent profile analysis was used to explore PTSS profiles in a sample of Norwegian Afghanistan veterans ( = 4052, 91.7% males). Multinomial logistic regression analyses were conducted to examine predictors and outcomes associated with PTSS profile membership. Three profiles emerged: profile (85%); profile (13%); and profile (2%). Being female, lower number of deployments, barriers to disclose war-related experiences, and higher number of potentially morally injurious events (PMIEs) were associated with belonging to the profile compared to the (Male gender: OR = 0.37,  < .05; Number of deployments: OR = 0.68,  < .05; Barriers to disclose: OR = 1.39,  < .001; PMIEs: OR = 1.15.  < .05), or profile (Male gender: OR = 0.36,  < .05; Number of deployments: OR = 0.67, < .01; Barriers to disclose: OR = 1.80,  < .001; PMIEs: OR = 1.32.  < .001). Participants in the profile had the highest probability of mental health service use (0.37) and endorsing suicidal ideation (0.38), compared to the two other profiles ( < .01). Participants in the profile had a higher probability of seeking professional mental health care (0.17), endorsing suicidal ideation (0.16), and reporting more suicide attempts compared to the profile (0.02 vs. 0.00,  < .001). These findings highlight the importance of considering the heterogeneity of PTSS profiles and understanding the predictors and responses of individuals who exhibit elevated PTSS symptoms.
Factors Associated With Increased Substance Use Disorder Care in VA PTSD Specialty Outpatient Treatment
Tiet QQ, Davis L, Rosen C, Norman SB, Leyva YE and Duong H
Substance use disorders (SUDs) commonly co-occur with posttraumatic stress disorder (PTSD). Understanding PTSD clinics that serve higher percentages of patients with PTSD/SUD is crucial for improving SUD care in clinics with lower percentages of such patients. This study examined the differences between Veterans Affairs (VA) PTSD treatment sites with higher percentages ("High%") and lower percentages ("Low%") of patients with PTSD/SUD as well as exploring the roles of the PTSD/SUD specialists. The study collected quantitative and qualitative data from 18 clinic directors and 21 specialists from 33 VA PTSD specialty outpatient clinics from 2014 to 2016. The clinics were chosen from the top and bottom quartiles based on two criteria: (1) the percentage of patients with PTSD/SUD and (2) the percentage of patients with PTSD/SUD who completed at least three SUD visits within the first month of their SUD treatment. The interviews sought to identify distinguishing characteristics between the High% and Low% clinics in terms of treatment access and practices for patients with PTSD/SUD. More of the High% clinics reported providing evidence-based, patient-centered, and integrated/concurrent PTSD/SUD treatment and had staff members with more up-to-date knowledge and skills than the Low% clinics. We also found the roles of the PTSD/SUD specialists were demanding and confusing, leading to high turnover rates. The two groups of PTSD clinics differed in three key factors: Resources, knowledge and skills of staff members, and local policies. Future research should focus on addressing resource limitations, knowledge gaps, and local policy disparities in Low% clinics. By emulating the practices of High% clinics, VA PTSD clinics can improve SUD care for patients with PTSD/SUD.
Quantifying Posttraumatic Stress Disorder Symptoms During Traumatic Memories Using Interpretable Markers of Respiratory Variability

Posttraumatic stress disorder (PTSD) causes heightened fight-or-flight responses to traumatic memories (i.e., hyperarousal). Although hyperarousal is hypothesized to cause irregular breathing (i.e., respiratory variability), no quantitative markers of respiratory variability have been shown to correspond with PTSD symptoms in humans.
The mental health toll among healthcare workers during the COVID-19 Pandemic in Malawi
Maliwichi L, Kondowe F, Mmanga C, Mchenga M, Kainja J, Nyamali S and Ndasauka Y
The COVID-19 pandemic has affected the mental health of healthcare workers worldwide, with frontline personnel experiencing heightened rates of depression, anxiety, and posttraumatic stress. This mixed-methods study aimed to assess the mental health toll of COVID-19 on healthcare workers in Malawi. A cross-sectional survey utilising the Generalized Anxiety Disorder (GAD-7), Patient Health Questionnaire (PHQ-9), and Primary Care PTSD Screen for DSM-5 (PC-PTSD-5) was conducted among 109 frontline healthcare workers. Additionally, in-depth interviews were conducted with 16 healthcare workers to explore their experiences and challenges during the pandemic. The results indicated a high prevalence of COVID-19-related depression (31%; CI [23, 41]), anxiety (30%; CI [22, 40]), and PTSD (25%; CI [17, 34]) among participants. Regression analysis revealed significantly higher rates of depression, anxiety, and PTSD among healthcare workers in city referral hospitals compared to district hospitals. Qualitative findings highlighted the emotional distress, impact on work and personal life, and experiences of stigma and discrimination faced by healthcare workers. The stress process model provided a valuable framework for understanding the relationship among pandemic-related stressors, coping resources, and mental health outcomes. The findings underscore the urgent need for interventions and support systems to mitigate the mental health impact of COVID-19 on frontline healthcare workers in Malawi. Policymakers should prioritise the assessment and treatment of mental health problems among this critical workforce to maintain an effective pandemic response and build resilience for future crises.
Associations between trauma exposure and irritability within the family unit: a network approach
Cotter G, Morreale K, Valdegas A, Fish M, Beebe R, Grasso D, Stover C and Tseng WL
Pediatric irritability is a pervasive psychiatric symptom, yet its etiology remains elusive. While trauma exposure may contribute to the development of irritability, empirical research is limited. This study examined the prevalence of irritability among trauma-exposed children, identified factors that differentiate trauma-exposed children with and without irritability, and employed a network analysis to uncover associations between irritability and trauma exposure in the family unit.
Transgender people in clinical trials of drugs and biologics: An analysis of ClinicalTrials.gov from 2007 to 2023
Schonrock Z, Brackeen S, Delarose KE, Tran TQ and Cirrincione LR
Transgender people have unmet health needs related to chronic conditions such as dementia, osteoporosis and hypertension. Community-driven advocacy increased transgender representation in phase III trials for pharmacological prevention of HIV, but the extent to which drug trials for other conditions have included transgender people is unknown. We investigated the extent to which trials of drugs and biologics represented transgender people across therapeutic areas on ClinicalTrials.gov.
International Trauma Questionnaire and Posttraumatic Cognitions Inventory-9: validity evidence and measurement invariance of their Brazilian versions
Aprigio I, Dos Santos PPP and Gauer G
The International Trauma Questionnaire (ITQ) is used to measure posttraumatic stress disorder (PTSD) and complex posttraumatic stress disorder (CPTSD) symptoms, and the Posttraumatic Cognitions Inventory-9 (PTCI-9) is used to measure posttraumatic cognitions. Both tools have been translated for use in Brazil. However, the psychometric properties of the Brazilian versions were not investigated, and no study has verified the invariance of these tools for many traumatic event types.
Lower vascular conductance responses to handgrip exercise are improved following acute antioxidant supplementation in young individuals with post-traumatic stress disorder
Weggen JB, Darling AM, Autler AS, Hogwood AC, Decker KP, Richardson J, Tuzzolo G and Garten RS
Young individuals with post-traumatic stress disorder (PTSD) display peripheral vascular and autonomic nervous system dysfunction, two factors potentially stemming from a redox imbalance. It is currently unclear if these aforementioned factors, observed at rest, alter peripheral haemodynamic responses to exercise in this population. This study examined haemodynamic responses to handgrip exercise in young individuals with PTSD following acute antioxidant (AO) supplementation. Thirteen young individuals with PTSD (age 23 ± 3 years), and 13 age- and sex-matched controls (CTRL) participated in the study. Exercise-induced changes to arm blood flow (BF), mean arterial pressure (MAP) and vascular conductance (VC) were evaluated across two workloads of rhythmic handgrip exercise (3 and 6 kg). The PTSD group participated in two visits, consuming either a placebo (PL) or AO prior to their visits. The PTSD group demonstrated significantly lower VC (P = 0.04) across all exercise workloads (vs. CTRL), which was significantly improved following AO supplementation. In the PTSD group, AO supplementation improved VC in participants possessing the lowest VC responses to handgrip exercise, with AO supplementation significantly improving VC responses (3 and 6 kg: P < 0.01) by blunting elevated exercise-induced MAP responses (3 kg: P = 0.01; 6 kg: P < 0.01). Lower VC responses during handgrip exercise were improved following AO supplementation in young individuals with PTSD. AO supplementation was associated with a blunting of exercise-induced MAP responses in individuals with PTSD displaying elevated MAP responses. This study revealed that young individuals with PTSD exhibit abnormal, peripherally mediated exercise responses that may be linked to a redox imbalance.
Tobacco use, trauma exposure and PTSD: a systematic review
Shevorykin A, Hyland BM, Robles D, Ji M, Vantucci D, Bensch L, Thorner H, Marion M, Liskiewicz A, Carl E, Ostroff JS and Sheffer CE
Tobacco use remains one of the most significant preventable public health problems globally and is increasingly concentrated among vulnerable groups, including those with trauma exposure or diagnosed with PTSD. The goal of this systematic review was to update and extend previous reviews. Of the 7224 publications that met the initial criteria, 267 were included in the review. Summary topic areas include conceptual frameworks for the relation between trauma or PTSD and tobacco use; associations between trauma exposure or PTSD and tobacco use; number and type of trauma exposures and tobacco use; PTSD symptoms and tobacco use; Treatment-related studies; and the examination of causal relations. Evidence continues to indicate that individuals exposed to trauma or diagnosed with PTSD are more likely to use tobacco products, more nicotine dependent and less likely to abstain from tobacco even when provided evidence-based treatments than individuals without trauma. The most commonly cited causal association proposed was use of tobacco for self-regulation of negative affect associated with trauma. A small proportion of the studies addressed causality and mechanisms of action. Future work should incorporate methodological approaches and measures from which we can draw causal conclusions and mechanisms to support the development of viable therapeutic targets.
GABAergic interneurons in the hippocampal CA1 mediate contextual fear generalization in PTSD rats
Gong X, Fan Z, Xu H, Qu Y, Li B, Li L, Yan Y, Wu L and Yan C
Fear overgeneralization is widely accepted as a pathogenic marker of post-traumatic stress disorder (PTSD). Recently, GABAergic interneurons have been regarded as key players in the regulation of fear memory. The role of hippocampal GABAergic interneurons in contextual fear generalization of PTSD remains incompletely understood. In the present study, we established a rat model of PTSD with inescapable foot shocks (IFS) and observed the loss of GABAergic interneuron phenotype in the hippocampal cornu ammonis-1 (CA1) subfield. To determine whether the loss of GABAergic interneuron phenotype was associated with fear generalization in PTSD rats, we used adeno-associated virus (AAV) to reduce the expression of GAD67 in CA1 and observed its effect on fear generalization. The results showed that the reduction of GAD67 in CA1 enhanced contextual fear generalization in rats. We investigated whether the PERK pathway was involved in the GABAergic interneuron injury. Increased expression of p-PERK, CHOP, and Caspase12 in GABAergic interneurons of PTSD rats was observed. Then, we used salubrinal, an endoplasmic reticulum stress inhibitor, to modulate the PERK pathway. The salubrinal treatment significantly protected the GABAergic interneurons and relieved fear generalization in PTSD rats. In addition, the results showed that salubrinal down-regulated the expression of CHOP and Caspase12 in GABAergic interneurons of PTSD rats. In conclusion, this study provided evidence that the loss of GABAergic interneuron phenotype in CA1 may contribute to contextual fear generalization in PTSD. The PERK pathway is involved in the GABAergic interneuron injury of PTSD rats and modulating it can protect GABAergic interneurons and constrain contextual fear generalization.
An open pilot trial of a behavioural intervention to reduce violence by young adults with early psychosis receiving treatment in an early intervention services setting: A protocol
Rolin SA, Caffrey D, Flores MG, Pope LG, Mootz J, Bello I, Nossel I, Compton MT, Stanley B, Wainberg M, Dixon LB and Appelbaum PS
Despite the public health impact of violence among young adults with psychosis, behavioural interventions to reduce the risk of engaging in violence remain rare. For young adults with early psychosis, cognitive behavioural therapy (CBT)-based psychotherapy has efficacy in reducing impairment and improving functioning. However, no CBT-based intervention to reduce violence has been formally adapted for young adults with early psychosis. This protocol outlines the first clinical trial of a behavioural intervention to reduce violence for young adults with early psychosis. This study is set in an early intervention services (EIS) setting and seeks to adapt and pilot Psychological Intervention for Complex PTSD and Schizophrenia-Spectrum Disorder (PICASSO), a CBT-based intervention, through an iterative process utilizing mixed-methods assessments.
Zebrafish Model in Illuminating the Complexities of Post-Traumatic Stress Disorders: A Unique Research Tool
Al-Zoubi RM, Abu-Hijleh H, Zarour A, Zakaria ZZ, Yassin A, Al-Ansari AA, Al-Asmakh M and Bawadi H
Post-traumatic stress disorder (PTSD) is a debilitating psychological condition that may develop in certain individuals following exposure to life-threatening or traumatic events. Distressing symptoms, including flashbacks, are characterized by disrupted stress responses, fear, anxiety, avoidance tendencies, and disturbances in sleep patterns. The enduring effects of PTSD can profoundly impact personal and familial relationships, as well as social, medical, and financial stability. The prevalence of PTSD varies among different populations and is influenced by the nature of the traumatic event. Recently, zebrafish have emerged as a valuable model organism in studying various conditions and disorders. Zebrafish display robust behavioral patterns that can be effectively quantified using advanced video-tracking tools. Due to their relatively simple nervous system compared to humans, zebrafish are particularly well suited for behavioral investigations. These unique characteristics make zebrafish an appealing model for exploring the underlying molecular and genetic mechanisms that govern behavior, thus offering a powerful comparative platform for gaining deeper insights into PTSD. This review article aims to provide updates on the pathophysiology of PTSD and the genetic responses associated with psychological stress. Additionally, it highlights the significance of zebrafish behavior as a valuable tool for comprehending PTSD better. By leveraging zebrafish as a model organism, researchers can potentially uncover novel therapeutic interventions for the treatment of PTSD and contribute to a more comprehensive understanding of this complex condition.
Infralimbic activity during REM sleep facilitates fear extinction memory
Hong J, Choi K, Fuccillo MV, Chung S and Weber F
Rapid eye movement (REM) sleep is known to facilitate fear extinction and play a protective role against fearful memories. Consequently, disruption of REM sleep after a traumatic event may increase the risk for developing PTSD. However, the underlying mechanisms by which REM sleep promotes extinction of aversive memories remain largely unknown. The infralimbic cortex (IL) is a key brain structure for the consolidation of extinction memory. Using calcium imaging, we found in mice that most IL pyramidal neurons are intensively activated during REM sleep. Optogenetically suppressing the IL specifically during REM sleep within a 4-h window after auditory-cued fear conditioning impaired extinction memory consolidation. In contrast, REM-specific IL inhibition after extinction learning did not affect the extinction memory. Whole-cell patch-clamp recordings demonstrated that inactivating IL neurons during REM sleep depresses their excitability. Together, our findings suggest that REM sleep after fear conditioning facilitates fear extinction by enhancing IL excitability and highlight the importance of REM sleep in the aftermath of traumatic events for protecting against traumatic memories.
The Maternal Psychic Impact of Infection by SARS-CoV-2 during Pregnancy: Results from a Preliminary Prospective Study
Benzakour L, Gayet-Ageron A and Epiney M
Due to a higher risk of maternal complications during pregnancy, as well as pregnancy complications such as stillbirth, SARS-CoV-2 contamination during pregnancy is a putative stress factor that could increase the risk of perinatal maternal mental health issues. We included women older than 18 years, who delivered a living baby at the Geneva University Hospitals' maternity wards after 29 weeks of amenorrhea (w.a.) and excluded women who did not read or speak fluent French. We compared women who declared having had COVID-19, confirmed by a positive PCR test for SARS-CoV-2, during pregnancy with women who did not, both at delivery and at one month postpartum. We collected clinical data by auto-questionnaires between time of childbirth and the third day postpartum regarding the occurrence of perinatal depression, peritraumatic dissociation, and peritraumatic distress during childbirth, measured, respectively, by the EPDS (depression is score > 11), PDI (peritraumatic distress is score > 15), and PDEQ (scales). At one month postpartum, we compared the proportion of women with a diagnosis of postpartum depression (PPD) and birth-related posttraumatic stress disorder (CB-PTSD), using PCL-5 for CB-PTSD and using diagnosis criteria according DSM-5 for both PPD and CB-PTSD, in the context of a semi-structured interview, conducted by a clinician psychologist. Off the 257 women included, who delivered at the University Hospitals of Geneva between 25 January 2021 and 10 March 2022, 41 (16.1%) declared they had a positive PCR test for SARS-CoV-2 during their pregnancy. Regarding mental outcomes, except birth-related PTSD, all scores provided higher mean values in the group of women who declared having been infected by SARS-CoV-2, at delivery and at one month postpartum, without reaching any statistical significance: respectively, 7.8 (±5.2, 8:4-10.5) versus 6.5 (±4.7, 6:3-9), = 0.139 ***, for continuous EPDS scores; 10 (25.0) versus 45 (21.1), = 0.586 *, for dichotomous EPDS scores (≥11); 118 (55.7) versus 26 (63.4), = 0.359 *, for continuous PDI scores; 18.3 (±6.8, 16:14-21) versus 21.1 (±10.7, 17:15-22), 0.231 ***, for dichotomous PDI scores (≥15); 14.7 (±5.9, 13:10-16) versus 15.7 (±7.1, 14:10-18), = 0.636 ***, for continuous PDEQ scores; 64 (30.0) versus 17 (41.5), = 0.151 *, for dichotomous PDEQ scores (≥15); and 2 (8.0) versus 5 (3.6), = 0.289 *, for postpartum depression diagnosis, according DSM-5. We performed Chi-squared or Fisher's exact tests, depending on applicability for the comparison of categorical variables and Mann-Whitney nonparametric tests for continuous variables; < 0.05 was considered as statistically significant. Surprisingly, we did not find more birth-related PTSD as noted by the PCL-5 score at one month postpartum in women who declared a positive PCR test for SARS-CoV-2:15 (10.6) versus no case of birth related PTSD in women who were infected during pregnancy ( = 0.131 *). Our study showed that mental outcomes were differently distributed between women who declared having been infected by SARS-CoV-2 compared to women who were not infected. However, our study was underpowered to explore all the factors associated with psychiatric issues during pregnancy, postpartum, depending on the exposure to SARS-CoV-2 infection during pregnancy. Future longitudinal studies on bigger samples and more diverse populations over a longer period are needed to explore the long-term psychic impact on women who had COVID-19 during pregnancy.

Longitudinal changes in the PTSD symptom network following trauma-focused treatment in military populations: Identifying central symptoms and the role of military sexual trauma
Xu B, Kim S, Blais RK, Nadel M, Cai Q and Tanev KS
Posttraumatic stress disorder (PTSD) is a debilitating condition affecting military populations, with a higher prevalence compared to the general population. Despite the development of first-line trauma-focused treatments such as Cognitive Processing Therapy (CPT) and Prolonged Exposure Therapy (PE), a significant proportion of patients continue to experience persistent PTSD symptoms following treatment. This study utilized network analysis to explore the PTSD symptom network's dynamics pre- and post- trauma-focused treatment and investigated the role of military sexual trauma (MST) history in shaping the network. Network analysis is a novel approach that can guide treatment target areas. The sample was comprised of 1648 service members and veterans who participated in a two-week intensive PTSD treatment program, which included completion of evidenced-based individual therapy as well as skill-building focused group therapy. PTSD severity was assessed using the PTSD Checklist for DSM-5 at baseline and post-treatment. Network analyses revealed strong connections within symptom clusters, with negative emotions emerging as one of the most central symptoms. Interestingly, the symptom network's overall structure remained stable following treatment, whereas global strength significantly increased. MST history did not significantly impact the network's structure or its change relative to treatment. Future research should further examine whether targeting negative emotions optimizes PTSD treatment outcomes for military populations.
Sleep Delta power, age, and sex effects in treatment-resistant depression
Hejazi NS, Duncan WC, Kheirkhah M, Kowalczyk A, Riedner B, Oppenheimer M, Momenan R, Yuan Q, Kerich M, Goldman D and Zarate CA
Electroencephalographic (EEG) deficits in slow wave activity or Delta power (0.5-4 Hz) indicate disturbed sleep homeostasis and are hallmarks of depression. Sleep homeostasis is linked to restorative sleep and potential antidepressant response via non-rapid eye movement (NREM) slow wave sleep (SWS) during which neurons undergo essential repair and rejuvenation. Decreased Low Delta power (0.5-2 Hz) was previously reported in individuals with depression. This study investigated power levels in the Low Delta (0.5-<2 Hz), High Delta (2-4 Hz), and Total Delta (0.5-4 Hz) bands and their association with age, sex, and disrupted sleep in treatment-resistant depression (TRD). Mann-Whitney U tests were used to compare the nightly progressions of Total Delta, Low Delta, and High Delta in 100 individuals with TRD and 24 healthy volunteers (HVs). Polysomnographic parameters were also examined, including Total Sleep Time (TST), Sleep Efficiency (SE), and Wake after Sleep Onset (WASO). Individuals with TRD had lower Delta power during the first NREM episode (NREM1) than HVs. The deficiency was observed in the Low Delta band versus High Delta. Females with TRD had higher Delta power than males during the first NREM1 episode, with the most noticeable sex difference observed in Low Delta. In individuals with TRD, Low Delta power correlated with WASO and SE, and High Delta correlated with WASO. Low Delta power deficits in NREM1 were observed in older males with TRD, but not females. These results provide compelling evidence for a link between age, sex, Low Delta power, sleep homeostasis, and non-restorative sleep in TRD.
Predicting DSM-5 PTSD symptomatology 6 months to 2 years after burn: The role of early psychological risk factors
Su YJ
Major burn injuries may have long-term mental health consequences, such as posttraumatic stress disorder (PTSD). This study extended prior work to investigate DSM-5 PTSD symptoms at 6 months, 1 year, and 2 years post-burn as well as the contribution of two sets of early psychological risk factors to DSM-5 PTSD symptoms: Established PTSD risk factors (prior adjustment problems, past trauma, perception of life threat, peritraumatic emotions and dissociation) and theory-derived cognitive factors (negative appraisals of the trauma and its sequelae, memory disorganization, trauma-related rumination, and thought suppression).
Exploring the impact of music on response to ketamine/esketamine: A scoping review
Kheirkhah M, Nugent AC, Livinski AA, Neely L, Johnson SC, Henter ID, Varnosfaderani SD, Price RB, Hejazi N, Yavi M, Jamalabadi H, Javaheripour N, Walter M and Zarate CA
Music and ketamine are both known to affect therapeutic outcomes, but few studies have investigated their co-administration. This scoping review describes the existing literature on the joint use of music and ketamine-or esketamine (the S(+) enantiomer of ketamine)-in humans. The review considers that extant studies have explored the intersection of ketamine/esketamine and music in healthy volunteers and in patients of various age groups, at different dosages, through different treatment processes, and have varied the sequence of playing music relative to ketamine/esketamine administration. Studies investigating the use of music during ketamine anesthesia are also included in the review because anesthesia and sedation were the early drivers of ketamine use. Studies pertaining to recreational ketamine use were omitted. The review was limited to articles published in the English language but not restricted by publication year. To the best of our knowledge, this scoping review is the first comprehensive exploration of the interplay between music and ketamine/esketamine and offers valuable insights to researchers interested in designing future studies.
Joint developmental trajectories of depression and post-traumatic stress disorder symptoms among Chinese children during COVID-19
Zhao Y, Sun X, Yuan GF, Jin J and Miao J
In early 2020, Chinese children started to demonstrate severe depression and post-traumatic stress disorder symptoms (PTSS) caused by lockdown and self-isolation (measures taken at the beginning of the COVID-19 pandemic).
Risk of Suicide and Self-Harm Following Gender-Affirmation Surgery
Straub JJ, Paul KK, Bothwell LG, Deshazo SJ, Golovko G, Miller MS and Jehle DV
Introduction With the growing acceptance of transgender individuals, the number of gender affirmation surgeries has increased. Transgender individuals face elevated depression rates, leading to an increase in suicide ideation and attempts. This study evaluates the risk of suicide or self-harm associated with gender affirmation procedures. Methods This retrospective study utilized de-identified patient data from the TriNetX (TriNetX, LLC, Cambridge, MA) database, involving 56 United States healthcare organizations and over 90 million patients. The study involved four cohorts: cohort A, adults aged 18-60 who had gender-affirming surgery and an emergency visit (N = 1,501); cohort B, control group of adults with emergency visits but no gender-affirming surgery (N = 15,608,363); and cohort C, control group of adults with emergency visits, tubal ligation or vasectomy, but no gender-affirming surgery (N = 142,093). Propensity matching was applied to cohorts A and C. Data from February 4, 2003, to February 4, 2023, were analyzed to examine suicide attempts, death, self-harm, and post-traumatic stress disorder (PTSD) within five years of the index event. A secondary analysis involving a control group with pharyngitis, referred to as cohort D, was conducted to validate the results from cohort C. Results Individuals who underwent gender-affirming surgery had a 12.12-fold higher suicide attempt risk than those who did not (3.47% vs. 0.29%, RR 95% CI 9.20-15.96, p < 0.0001). Compared to the tubal ligation/vasectomy controls, the risk was 5.03-fold higher before propensity matching and remained significant at 4.71-fold after matching (3.50% vs. 0.74%, RR 95% CI 2.46-9.024, p < 0.0001) for the gender affirmation patients with similar results with the pharyngitis controls. Conclusion Gender-affirming surgery is significantly associated with elevated suicide attempt risks, underlining the necessity for comprehensive post-procedure psychiatric support.
Racial/Ethnic Differences in Adverse Childhood Experiences and Mental Health

Imagery rescripting and extinction: Effects on US expectancy, US revaluation, and the generalization of fear reduction
Woelk M, Hagenaars MA, Raes F, Vervliet B and Krans J
Exposure therapy consists of exposing patients to their fears and thereby diminishing their harm expectancies (i.e., extinction or expectancy learning). Although effective for many anxiety patients, its long-term success depends on the generalization of these harm expectancies to other stimuli. However, research shows that this generalization of extinction is limited. Besides decreasing harm expectancies, fear reduction may also be achieved by changing the meaning of an aversive memory representation (US revaluation). Imagery rescripting (ImRs) may be more successful in generalizing fear reduction because it allegedly works through US revaluation. The current experiment aimed to test working mechanisms for ImRs and extinction (revaluation and expectancy learning, respectively), and to examine generalization of fear reduction. In a fear conditioning paradigm, 113 healthy participants watched an aversive film clip that was used as the US. The manipulation consisted of imagining a script with a positive ending to the film clip (ImRs-only), extinction (extinction-only), or both (ImRs + extinction). Results showed enhanced US revaluation in ImRs + extinction. US expectancy decreased more strongly in the extinction conditions. Generalization of fear reduction was found in all conditions. Our results suggest different working mechanisms for ImRs and exposure. Future research should replicate this in (sub)clinical samples.

Psychometric evaluation of the PCL-5: assessing validity, diagnostic utility, and bifactor structures
Georgescu T, Nedelcea C, Gorbănescu A, Papasteri C, Cosmoiu AM, Vasile DL and Letzner RD
The changes DSM-5 brought to the diagnostic criteria for posttraumatic stress disorder (PTSD) resulted in revising the most widely used instrument in assessing PTSD, namely the Posttraumatic Checklist for DSM-5 (PCL-5). This study examined the psychometric properties of the Romanian version of the PCL-5, tested its diagnostic utility against the Structured Clinical Interview for DSM-5 (SCID-5), and investigated the latent structure of PTSD symptoms through correlated symptom models and bifactor modelling. A total sample of 727 participants was used to test the psychometric properties and underlying structure of the PCL-5 and 101 individuals underwent clinical interviews using SCID-5. Receiver operating characteristic curve (ROC) analyses were performed to test the diagnostic utility of the PCL-5 and identify optimal cut-off scores based on Youden's index. Confirmatory Factor Analyses (CFAs) and bifactor modelling were performed to investigate the latent structure of PTSD symptoms. Estimates revealed that the PCL-5 is a valuable tool with acceptable diagnostic accuracy compared to SCID-5 diagnoses, indicating a cut-off score of >47. The CFAs provide empirical support for Anhedonia, Hybrid, and bifactor models. The findings are limited by using retrospective, self-report data and the high percentage of female participants. The PCL-5 is a psychometrically sound instrument that can be useful in making provisional diagnoses within community samples and improving trauma-informed practices.
Implementation of positive psychology to surmount demoralization caused by a cataclysm in select works of Svetlana Alexievich
Syeda PSJ and Devi R
Cataclysm refers to a large-scale and violent event involving disaster, catastrophe, calamity, and tragedy. The recent surge of a pandemic (coronavirus disease 2019 (COVID-19)), humanitarian crisis in Sudan, civil unrest, and war, such as the attacks in Syria and Ukraine, reiterate the need to address the trauma attached to such catastrophes. This study focuses on adapting positive psychology, one of the newest branches of psychology to emerge, to help human beings prosper and lead healthy, happy lives. It also explores post-traumatic stress disorder (PTSD) and means to overcome traumatizing psychological dejection caused by such mishaps.
[The psychotrauma prevention algorithm, a paramedical pilot study]
René É, Bruneau L and Gokalsing E
The aim of the psychotrauma prevention algorithm is to limit the occurrence of psychotrauma in a subject who has experienced a serious life event, by carrying out an initial assessment to define the severity criterion and the monitoring modality best suited to his or her clinical condition. This approach is in line with the philosophy of outreach and the ethics of concern. Recontacting the patient during the course of treatment helps to maintain the therapeutic link and prevent any deterioration in his condition, thus limiting the risk of his traumatic state becoming chronic.
A conceptual framework for a neurophysiological basis of art therapy for PTSD
Malhotra B, Jones LC, Spooner H, Levy C, Kaimal G and Williamson JB
Post-traumatic stress disorder (PTSD) is a heterogeneous condition that affects many civilians and military service members. Lack of engagement, high dropout rate, and variable response to psychotherapy necessitates more compelling and accessible treatment options that are based on sound neuroscientific evidence-informed decision-making. Art therapy incorporates elements proven to be effective in psychotherapy, such as exposure, making it a potentially valuable treatment option. This conceptual paper aims to inform the neurophysiological rationale for the use of art therapy as a therapeutic approach for individuals with PTSD. A narrative synthesis was conducted using literature review of empirical research on the neurophysiological effects of art therapy, with supporting literature on neuroaesthetics and psychotherapies to identify art therapy factors most pertinent for PTSD. Findings were synthesized through a proposed framework based on the triple network model considering the network-based dysfunctions due to PTSD. Art therapy's active components, such as concretization and metaphor, active art engagement, emotion processing and regulation, perspective taking and reframing, and therapeutic alliance, may improve symptoms of PTSD and prompt adaptive brain functioning. Given the scarcity of rigorous studies on art therapy's effectiveness and mechanisms of alleviating PTSD symptoms, the suggested framework offers a neurophysiological rationale and a future research agenda to investigate the impact of art therapy as a therapeutic approach for individuals with PTSD.
Psychological Group Interventions for Reducing Distress Symptoms in Healthcare Workers: A Systematic Review
Sanz S, Valiente C, Espinosa R and Trucharte A
Healthcare workers exposed to emergencies and chronic stressors are at high risk of developing mental health problems. This review synthesized existing studies of group psychological therapy to reduce distress symptoms in healthcare workers (i.e., as complex and heterogeneous emotional states, characterized by the presence of symptoms associated with post-traumatic stress disorder, burnout, anxiety, depression and moral injury). Searches were conducted using PRISMA guidelines and databases such as PubMed, PsycINFO, Medline and Web of Science, along with manual searches of reference lists of relevant articles. The search returned a total of 1071 randomized trials, of which 23 met the inclusion criteria. Of the total studies, nine were mindfulness interventions, seven were cognitive behavioural programmes, one was a programme based on acceptance and commitment therapy, one was an EMDR protocol and two focused on systemic and art therapy. Most studies aimed to reduce burnout, anxiety and depression; only three focused on post-traumatic stress disorder, and no studies were found that addressed moral injury. The results suggested that group interventions could be an effective tool to improve the mental health of healthcare workers and reduce their symptoms of distress, although many of the studies have methodological deficiencies. Limitations and future directions are discussed.
Association Between the Time Spent on and Sources of the News of Russo-Ukrainian War and Psychological Distress Among Individuals in Poland and Ukraine: The Mediating Effect of Rumination
Li DJ, Chudzicka-Czupała A, Paliga M, Hapon N, Karamushka L, Żywiołek-Szeja M, McIntyre RS, Chiang SK, Chen YL, Yen CF and Man RHC
The Russo-Ukrainian War has resulted in massive social, economic, and psychological burdens worldwide. This study aimed to investigate the associations between time spent on the war-related news and psychological distress, including depression, anxiety, and post-traumatic stress disorder (PTSD) and the mediating effects of rumination on the associations in people residing in Poland and Ukraine.
Experiences using an online therapist-guided psychotherapy platform (OPTT) in correctional workers with depression, anxiety, and PTSD
Moghimi E, Gutierrez G, Stephenson C, Gizzarelli T, Jagayat J, Holmes C, Patel C, Omrani M, Simpson AIF and Alavi N
Correctional workers (CWs) are frequently exposed to potentially traumatic events in the workplace, leading to an increased prevalence of mental health concerns. Online psychotherapy can address many of the barriers CWs face when seeking adequate mental health care. Despite their benefits, CWs' experience using digital mental health interventions is relatively unknown. This information could be valuable in developing enhanced care delivery to improve recruitment, retention, satisfaction, and treatment outcomes.
Pathophysiology in cortico-amygdala circuits and excessive aversion processing: the role of oligodendrocytes and myelination
Poggi G, Klaus F and Pryce CR
Stress-related psychiatric illnesses, such as major depressive disorder, anxiety and post-traumatic stress disorder, present with alterations in emotional processing, including excessive processing of negative/aversive stimuli and events. The bidirectional human/primate brain circuit comprising anterior cingulate cortex and amygdala is of fundamental importance in processing emotional stimuli, and in rodents the medial prefrontal cortex-amygdala circuit is to some extent analogous in structure and function. Here, we assess the comparative evidence for: (i) Anterior cingulate/medial prefrontal cortex<->amygdala bidirectional neural circuits as major contributors to aversive stimulus processing; (ii) Structural and functional changes in anterior cingulate cortex<->amygdala circuit associated with excessive aversion processing in stress-related neuropsychiatric disorders, and in medial prefrontal cortex<->amygdala circuit in rodent models of chronic stress-induced increased aversion reactivity; and (iii) Altered status of oligodendrocytes and their oligodendrocyte lineage cells and myelination in anterior cingulate/medial prefrontal cortex<->amygdala circuits in stress-related neuropsychiatric disorders and stress models. The comparative evidence from humans and rodents is that their respective anterior cingulate/medial prefrontal cortex<->amygdala circuits are integral to adaptive aversion processing. However, at the sub-regional level, the anterior cingulate/medial prefrontal cortex structure-function analogy is incomplete, and differences as well as similarities need to be taken into account. Structure-function imaging studies demonstrate that these neural circuits are altered in both human stress-related neuropsychiatric disorders and rodent models of stress-induced increased aversion processing. In both cases, the changes include altered white matter integrity, albeit the current evidence indicates that this is decreased in humans and increased in rodent models. At the cellular-molecular level, in both humans and rodents, the current evidence is that stress disorders do present with changes in oligodendrocyte lineage, oligodendrocytes and/or myelin in these neural circuits, but these changes are often discordant between and even within species. Nonetheless, by integrating the current comparative evidence, this review provides a timely insight into this field and should function to inform future studies-human, monkey and rodent-to ascertain whether or not the oligodendrocyte lineage and myelination are causally involved in the pathophysiology of stress-related neuropsychiatric disorders.

Three Prospective Case Studies Examining Mifepristone's Efficacy in Patients with Treatment-Resistant PTSD
van Minnen A, Vos L, Bet PM, de Jongh A, Linsen F, van Marle HJF, Meijer OC, Otte WM, Russcher M and Vinkers CH
Despite the availability of various treatment approaches for patients with posttraumatic stress disorder (PTSD), some patients do not respond to these therapies, and novel treatment approaches are needed. This study investigated the efficacy of mifepristone, a glucocorticoid receptor antagonist, in treatment-resistant PTSD patients. Three patients with PTSD who were resistant to standard psychological and pharmacological treatments were prescribed mifepristone (600-1,200 mg/day) for 1 week. A baseline-controlled single-case design was used, involving a 2-week baseline phase (no intervention), a 1-week intervention phase (mifepristone), and a 2-week postintervention phase. The primary outcome measure, self-reported PTSD symptom severity (PCL-5), was assessed daily, with participants providing their own control condition. Two of the three patients experienced a significant reduction in PTSD symptom severity after the intervention phase and no longer met the diagnostic criteria for PTSD. These positive results were maintained during long-term follow-up. These findings support the potential effectiveness of mifepristone in the treatment of patients with treatment-resistant PTSD. However, our findings must be interpreted with caution, and further studies with larger sample sizes and more rigorous designs are necessary to confirm the promising results.
Violence Exposure and Disability in Colombian Female Survivors of Intimate Partner Violence: the Mediating Role of Depressive Symptoms
Sandoval LM, Castro ES, Fandiño-Losada A, Pacichana-Quinayaz SG, Lennon SE and Gutiérrez-Martínez MI
Violence is an important public health problem and one of the main causes of deaths worldwide. The mental health consequences of surviving intimate partner violence (IPV) include depression, anxiety and post-traumatic stress disorder. Previous studies have identified that there is a relationship between depression and level of disability in female survivors of IPV. Estimating the direct, indirect or total effect of an exposure on an outcome makes it possible to identify mediating effects between a group of variables. Detecting mediation effects is useful for identifying casual pathways that generate a final outcome and provides a rationale for designing interventions to target the mediator, which in turn positively affects the outcome. The objective was to identify the mediating role of depressive symptoms on the relationship between IPV and disability.
Fabrication of nanocrystal forms of ᴅ-cycloserine and their application for transdermal and enteric drug delivery systems
Tsai HA, Shih TM, Tsai T, Hu JW, Lai YA, Hsiao JF and Tsai GE
ᴅ-cycloserine (DCS), an FDA-approved medicine for the treatment of tuberculosis, is also a partial agonist at the glycine recognition site of -methyl-ᴅ-aspartate (NMDA) receptor and has shown significant treatment efficacy for central nervous system (CNS) disorders including depression, schizophrenia, Alzheimer's disease, and post-traumatic stress disorder. The physicochemical properties of DCS, however, limit the options of formulation and medicinal applications of DCS, and warrants further investigation for the development of CNS therapeutics. Nanocrystals play an important role in pharmaceutic design and development. The properties of nanocrystals are remarkably different from their bulk material counterpart, attributed to the large surface-area-to-volume ratio which can improve the bioavailability. In this study, for the first time, DCS, a highly water-soluble compound, has formed nanocrystals and this was confirmed by scanning electronic microscopy and X-ray powder diffraction. Furthermore, DCS nanocrystals were applied to several formulations to test their stability and then to the in vitro Franz diffusion test with reservoir patch formulation as well as in vivo pharmacokinetics study with enteric capsules. We tested these formulations regarding their nanocrystal physical properties, size effect, and dissolution rate, respectively. We found that DCS nanocrystals showed good performance in the Franz diffusion test and rodent pharmacokinetic studies due to the nanoparticle size and faster dissolution as compared with the commercial DCS powder. These DCS nanocrystal formulations could offer a new approach for the development of an advanced drug delivery system for the treatment of CNS disorders.
Are All Substance-Involved Sexual Assaults Alike? A Comparison of Victim Alcohol Use, Drug Use, and Combined Substance Use in Sexual Assaults
O'Callaghan E and Ullman SE
Sexual assaults involving victim substance use at the time of the assault are common, but little is known about how different types of substances used at the time of the assault impact post-assault outcomes. The current study sought to compare victim alcohol use, drug use, and combined substance use in sexual assaults among a community sample of 693 victims. It was hypothesized that victims in the combined substance use assault type would report overall worse post-assault outcomes, more contextual and interpersonal traumas, and higher assault severity. Our results partially confirmed these hypotheses, but victims in the drug-involved assault type group overall reported higher assault severity and worse post-assault outcomes. These findings are probably partially attributed to the demographic characteristics of victims in the drug-only group (e.g. Black victims) who are more likely to experience a higher severity of violence. Implications for future research and policy regarding drug decriminalization are discussed.

Optimizing Family Presence through Medical Education
Yu R
AbstractMany family members are wary of asking whether they can be present in the intensive care unit (ICU) while patients are receiving care. However, the opportunity to be present can be profoundly beneficial, especially to family members as they approach the grieving process. In the long run, this may decrease emotional complications such as post-traumatic stress disorder (PTSD) and complex grief. Family presence may also be profoundly important to patients, who may find comfort in the presence of their loved ones. Optimizing the needs of distressed families remains a controversial topic because it may distract physicians from providing needed medical care. Both parties may benefit maximally, however, through proactive training and early education during medical school, as this article will outline. Family members who may want to visit but are unable to be present in person may also benefit through virtual telehealth visits. Finally, we acknowledge specific cases that may pose ethically difficult dilemmas for ICU providers. Solutions that may be optimal in these situations will be suggested.

[Dreaming of a psychomotrician in a medical-psychological emergency room]
Akian M and Pionnier É
The psychomotrician is a healthcare professional trained in mind-body approaches. They take into account sensoriality, motor skills, cognition, psyche and emotions in relation to the individual's environment and the expression of disorders. It  is an integral part of the treatment of post-traumatic stress disorder. For some years now, psychomotricians have been part of volunteer teams in medical-psychological emergency units, where they offer an integrative approach. Using the body and mediation as their working tools, they rely on non-verbal communication and body language to bring the patient back to the present moment within a reassuring framework.
A Preliminary Analysis of Psychiatric Service Dog Placements and Sleep Patterns of Partners of Veterans With PTSD
Nieforth LO, Leighton SC, Schwichtenberg AJ, MacDermid Wadsworth S and O'Haire ME
Partners of veterans diagnosed with posttraumatic stress disorder (PTSD) are at risk of a variety of challenges, and it is unknown whether psychiatric service dogs are disruptive to their sleep or provide similar benefits that are seen in the limited literature on veterans. As part of a larger clinical trial examining the efficacy of psychiatric service dogs for veterans with PTSD and their families, this study focused on sleep patterns of veterans' partners ( = 88), incorporating both subjective (clinically validated self-report surveys) and objective sleep measures (actigraphy). Linear regression was used to analyze differences in relation to group (intervention versus control) at follow up, controlling for baseline score. Results revealed no significant differences between groups for both the subjective surveys ( = 0.15; = 0.75) and the objective actigraphy measures ( = 0.06-0.98). This suggests that psychiatric service dogs are not disruptive, nor do they provide any benefits to partner sleep. Partners had sleep patterns on par with national norms at baseline and remained at such levels at follow up. Ultimately, using both subjective and objective measures, we found no impact of psychiatric service dogs on the sleep of veterans' partners.
