This study investigated posttraumatic stress disorder (PTSD) prevalence among a sample of intimate partner violence (IPV) survivors (n  =  77) who filed for restraining orders in rural Louisiana during the COVID-19 pandemic. IPV survivors were individually interviewed to assess their self-reported levels of perceived stress, resilience, potential PTSD, COVID-19-related experiences, and sociodemographic characteristics. Data were analyzed to differentiate group membership between two groups; non-PTSD and probable PTSD. Results suggest the probable PTSD group had lower levels of resilience and higher levels of perceived stress compared to the non-PTSD group. Findings suggest the importance of providing services during disaster to reduce PTSD for IPV survivors.

BACKGROUND: Incorporating genomic data into risk prediction has become an increasingly popular approach for rapid identification of individuals most at risk for complex disorders such as PTSD. Our goal was to develop and validate Methylation Risk Scores (MRS) using machine learning to distinguish individuals who have PTSD from those who do not. METHODS: Elastic Net was used to develop three risk score models using a discovery dataset (n = 1226; 314 cases, 912 controls) comprised of 5 diverse cohorts with available blood-derived DNA methylation (DNAm) measured on the Illumina Epic BeadChip. The first risk score, exposure and methylation risk score (eMRS) used cumulative and childhood trauma exposure and DNAm variables; the second, methylation-only risk score (MoRS) was based solely on DNAm data; the third, methylation-only risk scores with adjusted exposure variables (MoRSAE) utilized DNAm data adjusted for the two exposure variables. The potential of these risk scores to predict future PTSD based on pre-deployment data was also assessed. External validation of risk scores was conducted in four independent cohorts. RESULTS: The eMRS model showed the highest accuracy (92%), precision (91%), recall (87%), and f1-score (89%) in classifying PTSD using 3730 features. While still highly accurate, the MoRS (accuracy = 89%) using 3728 features and MoRSAE (accuracy = 84%) using 4150 features showed a decline in classification power. eMRS significantly predicted PTSD in one of the four independent cohorts, the BEAR cohort (beta = 0.6839, p=0.006), but not in the remaining three cohorts. Pre-deployment risk scores from all models (eMRS, beta = 1.92; MoRS, beta = 1.99 and MoRSAE, beta = 1.77) displayed a significant (p

Media exposure to graphic images of violence has proliferated in contemporary society, particularly with the advent of social media. Extensive exposure to media coverage immediately after the 9/11 attacks and the Boston Marathon bombings (BMB) was associated with more early traumatic stress symptoms; in fact, several hours of BMB-related daily media exposure was a stronger correlate of distress than being directly exposed to the bombings themselves. Researchers have replicated these findings across different traumatic events, extending this work to document that exposure to graphic images is independently and significantly associated with stress symptoms and poorer functioning. The media exposure-distress association also appears to be cyclical over time, with increased exposure predicting greater distress and greater distress predicting more media exposure following subsequent tragedies. The war in Israel and Gaza, which began on October 7, 2023, provides a current, real-time context to further explore these issues as journalists often share graphic images of death and destruction, making media-based graphic images once again ubiquitous and potentially challenging public well-being. For individuals sharing an identity with the victims or otherwise feeling emotionally connected to the Middle East, it may be difficult to avoid viewing these images. Through a review of research on the association between exposure to graphic images and public health, we discuss differing views on the societal implications of viewing such images and advocate for media literacy campaigns to educate the public to identify mis/disinformation and understand the risks of viewing and sharing graphic images with others.

Posttraumatic stress disorder (PTSD) can develop after trauma exposure. Some studies report that women develop PTSD at twice the rate of men, despite greater trauma exposure in men. Lipids and their metabolites (lipidome) regulate a myriad of key biological processes and pathways such as membrane integrity, oxidative stress, and neuroinflammation in the brain by maintaining neuronal connectivity and homeostasis. In this study, we analyzed the lipidome of 40 adults with PTSD and 40 trauma-exposed non-PTSD individuals (n = 20/sex/condition; 19-39 years old). Plasma samples were analyzed for lipidomics using Quadrupole Time-of-Flight (QToF) mass spectrometry. Additionally, ~ 90 measures were collected, on sleep, and mental and physical health indices. Poorer sleep quality was associated with greater PTSD severity in both sexes. The lipidomics analysis identified a total of 348 quantifiable known lipid metabolites and 1951 lipid metabolites that are yet unknown; known metabolites were part of 13 lipid subclasses. After adjusting for BMI and sleep quality, in women with PTSD, only one lipid subclass, phosphatidylethanolamine (PE) was altered, whereas, in men with PTSD, 9 out of 13 subclasses were altered compared to non-PTSD women and men, respectively. Severe PTSD was associated with 22% and 5% of altered lipid metabolites in men and women, respectively. Of the changed metabolites, only 0.5% measures (2 PEs and cholesterol) were common between women and men with PTSD. Several sphingomyelins, PEs, ceramides, and triglycerides were increased in men with severe PTSD. The correlations between triglycerides and ceramide metabolites with cholesterol metabolites and systolic blood pressure were dependent upon sex and PTSD status. Alterations in triglycerides and ceramides are linked with cardiac health and metabolic function in humans. Thus, disturbed sleep and higher body mass may have contributed to changes in the lipidome found in PTSD.

BACKGROUND: 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. METHOD: Studies published up to December 2022 were retrieved by searching Medline, Embase, PsychoINFO, Cumulative Index to Nursing and Allied Health electronic databases. The modified Newcastle-Ottawa Scale for cohort and cross-sectional studies was used to assess the methodological quality of included studies. This review was pre-registered in PROSPERO (CRD42021270526). RESULTS: Forty-nine studies involving 8,447 parents were included; 18 studies examined factors for PTS, 24 for anxiety and 7 for both. Only one study of anxiety factors was deemed to be of good quality. Studies generally included a small sample size and were methodologically heterogeneous. Pooling of data was not feasible. Previous history of mental health problems (four studies) and parental perception of more severe infant illness (five studies) were associated with increased risk of PTS, and had the strongest evidence. Shorter gestational age (≤ 33 weeks) was associated with an increased risk of anxiety (three studies) and very low birth weight (

Background/objectivesTrait mindfulness (TM) may protect against post-trauma mental health ailments and related impairment. Few studies have evaluated this association in the context of collective traumas using representative samples or longitudinal designs.Design/methodWe explored relationships between TM and collective trauma-related outcomes in a prospective, representative, probability-based sample of 1846 U.S. Gulf Coast residents repeatedly exposed to catastrophic hurricanes, assessed twice during the COVID-19 outbreak (Wave 1: 5/14/20-5/27/20; Wave 2: 12/21/21-1/11/22). Generalized estimating equations examined longitudinal relationships between TM, COVID-19-related fear/worry, hurricane-related fear/worry, global distress, and functional impairment; ordinary least squares regression analyses examined the cross-sectional association between TM and COVID-19-related posttraumatic stress symptoms (PTSS) at Wave 1. Event-related stressor exposure was explored as a moderator.ResultsIn covariate-adjusted models including pre-event mental health ailments and demographics, TM was negatively associated with COVID-19-related fear/worry, hurricane-related fear/worry, global distress, and functional impairment over time; in cross-sectional analyses, TM was negatively associated with COVID-19-related PTSS. TM moderated the relationship between COVID-19 secondary stressor exposure (e.g., lost job/wages) and both global distress and functional impairment over time.ConclusionsResults suggest TM may buffer adverse psychosocial outcomes following collective trauma, with some evidence TM may protect against negative effects of secondary stressor exposure.

Post-traumatic stress disorder (PTSD) genetics are characterized by lower discoverability than most other psychiatric disorders. The contribution to biological understanding from previous genetic studies has thus been limited. We performed a multi-ancestry meta-analysis of genome-wide association studies across 1,222,882 individuals of European ancestry (137,136 cases) and 58,051 admixed individuals with African and Native American ancestry (13,624 cases). We identified 95 genome-wide significant loci (80 new). Convergent multi-omic approaches identified 43 potential causal genes, broadly classified as neurotransmitter and ion channel synaptic modulators (for example, GRIA1, GRM8 and CACNA1E), developmental, axon guidance and transcription factors (for example, FOXP2, EFNA5 and DCC), synaptic structure and function genes (for example, PCLO, NCAM1 and PDE4B) and endocrine or immune regulators (for example, ESR1, TRAF3 and TANK). Additional top genes influence stress, immune, fear and threat-related processes, previously hypothesized to underlie PTSD neurobiology. These findings strengthen our understanding of neurobiological systems relevant to PTSD pathophysiology, while also opening new areas for investigation.

COVID-19 pandemic-related traumatic stress (PRTS) symptoms are reported in various populations, but risk factors in older adults with chronic medical conditions, remain understudied. We therefore examined correlates and pre-pandemic predictors of PRTS in older adults with hypertension during COVID-19. Participants in California, aged 61-92 years (n = 95), participated in a pre-pandemic healthy aging trial and later completed a COVID-19 assessment (May to September 2020). Those experiencing ⩾1 PRTS symptom (n = 40), and those without PRTS symptoms (n = 55), were compared. The PRTS+ group had poorer mental and general health and greater impairment in instrumental activities of daily living. Pre-pandemic biomarkers of vascular inflammation did not predict increased odds of PRTS; however, greater pre-pandemic anxiety and female gender did predict PRTS during COVID-19. Our findings highlight PRTS as a threat to healthy aging in older adults with hypertension; targeted approaches are needed to mitigate this burden, particularly for females and those with pre-existing anxiety.

BACKGROUND: Myocardial infarction secondary to spontaneous coronary artery dissection (SCAD) can be traumatic and potentially trigger posttraumatic stress disorder (PTSD). In a large, multicenter, registry-based cohort, we documented prevalence of lifetime and past-month SCAD-induced PTSD, as well as related treatment seeking, and examined a range of health-relevant correlates of SCAD-induced PTSD. METHODS AND RESULTS: Patients with SCAD were enrolled in the iSCAD (International SCAD) Registry. At baseline, site investigators completed medical report forms, and patients reported demographics, medical/SCAD history, psychosocial factors (including SCAD-induced PTSD symptoms), health behaviors, and health status via online questionnaires. Of 1156 registry patients, 859 patients (93.9% women; mean age, 52.3 years) completed questionnaires querying SCAD-induced PTSD. Nearly 35% (n=298) of patients met diagnostic criteria for probable SCAD-induced PTSD in their lifetime, and 6.4% (n=55) met criteria for probable past-month PTSD. Of 811 patients ever reporting any SCAD-induced PTSD symptoms, 34.8% indicated seeking treatment for this distress. However, 46.0% of the 298 patients with lifetime probable SCAD-induced PTSD diagnoses reported never receiving trauma-related treatment. Younger age at first SCAD, fewer years since SCAD, being single, unemployed status, more lifetime trauma, and history of anxiety were associated with greater past-month PTSD symptom severity in multivariable regression models. Greater past-month SCAD-induced PTSD symptoms were associated with greater past-week sleep disturbance and worse past-month disease-specific health status when adjusting for various risk factors. CONCLUSIONS: Given the high prevalence of SCAD-induced PTSD symptoms, efforts to support screening for these symptoms and connecting patients experiencing distress with empirically supported treatments are critical next steps.

Observational studies suggest that posttraumatic stress disorder (PTSD) increases risk for various autoimmune diseases. Insights into shared biology and causal relationships between these diseases may inform intervention approaches to PTSD and co-morbid autoimmune conditions. We investigated the shared genetic contributions and causal relationships between PTSD, 18 autoimmune diseases, and 3 immune/inflammatory biomarkers. Univariate MiXeR was used to contrast the genetic architectures of phenotypes. Genetic correlations were estimated using linkage disequilibrium score regression. Bi-directional, two-sample Mendelian randomization (MR) was performed using independent, genome-wide significant single nucleotide polymorphisms; inverse variance weighted and weighted median MR estimates were evaluated. Sensitivity analyses for uncorrelated (MR PRESSO) and correlated horizontal pleiotropy (CAUSE) were also performed. PTSD was considerably more polygenic (10,863 influential variants) than autoimmune diseases (median 255 influential variants). However, PTSD evidenced significant genetic correlation with nine autoimmune diseases and three inflammatory biomarkers. PTSD had putative causal effects on autoimmune thyroid disease (p = 0.00009) and C-reactive protein (CRP) (p = 4.3 × 10-7). Inferences were not substantially altered by sensitivity analyses. Additionally, the PTSD-autoimmune thyroid disease association remained significant in multivariable MR analysis adjusted for genetically predicted inflammatory biomarkers as potential mechanistic pathway variables. No autoimmune disease had a significant causal effect on PTSD (all p values > 0.05). Although causal effect models were supported for associations of PTSD with CRP, shared pleiotropy was adequate to explain a putative causal effect of CRP on PTSD (p = 0.18). In summary, our results suggest a significant genetic overlap between PTSD, autoimmune diseases, and biomarkers of inflammation. PTSD has a putative causal effect on autoimmune thyroid disease, consistent with existing epidemiologic evidence. A previously reported causal effect of CRP on PTSD is potentially confounded by shared genetics. Together, results highlight the nuanced links between PTSD, autoimmune disorders, and associated inflammatory signatures, and suggest the importance of targeting related pathways to protect against disease and disability.

BACKGROUND: Posttraumatic stress disorder (PTSD) has been associated with ischemic heart disease in women veterans, but evidence for associations with other cardiovascular disorders remains limited in this population. This retrospective longitudinal cohort study evaluated the association of PTSD with incident stroke/transient ischemic attack (TIA) in women veterans. METHODS AND RESULTS: Veterans Health Administration electronic health records were used to identify women veterans aged ≥18 years engaged with Veterans Health Administration health care from January 1, 2000 to December 31, 2019. We identified women veterans with and without PTSD without a history of stroke or TIA at start of follow-up. Propensity score matching was used to match groups on age, race or ethnicity, traditional cardiovascular risk factors, female-specific risk factors, a range of mental and physical health conditions, and number of prior health care visits. PTSD, stroke, TIA, and risk factors used in propensity score matching were based on diagnostic codes. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% CIs for associations of PTSD with an incident stroke/TIA composite. Subanalyses considered stroke and TIA separately, plus age- and race- or ethnicity-stratified analyses were carried out. The analytic sample included 208 092 women veterans (104 046 with and 104 046 without PTSD). PTSD was associated with a greater rate of developing stroke/TIA (HR, 1.33 [95% CI, 1.25-1.42], P

BACKGROUND: The prosocial compound ± 3,4-methylenedioxymethamphetamine (MDMA) is an amphetamine derivative that has shown promise as an adjunct to psychotherapy in the treatment of post-traumatic stress disorder. MDMA increases positive responses to social images, and it has been suggested that the ability of MDMA to positively bias social perception may underlie its therapeutic efficacy as a psychotherapy adjunct. However, the effect of the compound on affective responses to positive or negative social feedback has not been tested. AIMS: In this study, we aimed to test the effects of MDMA compared to placebo and the prototypical stimulant, methamphetamine (MA), on responses to positive and negative social feedback. METHODS: This was a double-blind, placebo-controlled, crossover trial (NCT03790618), comparing the effects of two doses of MDMA (0.75 mg/kg, 1.5 mg/kg) to both placebo and MA (20 mg) on responses to a personalized social feedback task, similar to a dating app, in healthy adult volunteers ages 18-40 (N = 36, 18 women, 18 men). RESULTS/OUTCOMES: The high dose of MDMA increased positive affective responses to social feedback. CONCLUSIONS/INTERPRETATIONS: These findings suggest one process by which MDMA may facilitate social connection. Further work is needed to understand how MDMA affects responses to more generalized types of social feedback and to understand these effects in clinical populations.

Although the cerebellum contributes to higher-order cognitive and emotional functions relevant to posttraumatic stress disorder (PTSD), prior research on cerebellar volume in PTSD is scant, particularly when considering subregions that differentially map on to motor, cognitive, and affective functions. In a sample of 4215 adults (PTSD n = 1642; Control n = 2573) across 40 sites from the ENIGMA-PGC PTSD working group, we employed a new state-of-the-art deep-learning based approach for automatic cerebellar parcellation to obtain volumetric estimates for the total cerebellum and 28 subregions. Linear mixed effects models controlling for age, gender, intracranial volume, and site were used to compare cerebellum volumes in PTSD compared to healthy controls (88% trauma-exposed). PTSD was associated with significant grey and white matter reductions of the cerebellum. Compared to controls, people with PTSD demonstrated smaller total cerebellum volume, as well as reduced volume in subregions primarily within the posterior lobe (lobule VIIB, crus II), vermis (VI, VIII), flocculonodular lobe (lobule X), and corpus medullare (all p-FDR

High rates of cannabis use among people with posttraumatic stress disorder (PTSD) have raised questions about the efficacy of evidence-based PTSD treatments for individuals reporting cannabis use, particularly those with co-occurring alcohol or other substance use disorders (SUDs). Using a subset of four randomized clinical trials (RCTs) included in Project Harmony, an individual patient meta-analysis of 36 RCTs (total N = 4046) of treatments for co-occurring PTSD+SUD, we examined differences in trauma-focused (TF) and non-trauma-focused (non-TF) treatment outcomes for individuals who did and did not endorse baseline cannabis use (N = 410; 70% male; 33.2% endorsed cannabis use). Propensity score-weighted mixed effects modeling evaluated main and interactive effects of treatment assignment (TF versus non-TF) and baseline cannabis use (yes/no) on attendance rates and within-treatment changes in PTSD, alcohol, and non-cannabis drug use severity. Results revealed significant improvements across outcomes among participants in all conditions, with larger PTSD symptom reductions but lower attendance among individuals receiving TF versus non-TF treatment in both cannabis groups. Participants achieved similar reductions in alcohol and drug use across all conditions. TF outperformed non-TF treatments regardless of recent cannabis use, underscoring the importance of reducing barriers to accessing TF treatments for individuals reporting cannabis use.

BACKGROUND: There is currently a deficit of knowledge about how to define, quantify, and measure different aspects of daily routine disruptions amid large-scale disasters like COVID-19, and which psychiatric symptoms were more related to the disruptions. This study aims to conduct a systematic review and meta-analysis on the probable positive associations between daily routine disruptions and mental disorders amid the COVID-19 pandemic and factors that moderated the associations. METHODS: PsycINFO, Web of Science, PubMed, and MEDLINE were systematically searched up to April 2023 (PROSPERO: CRD42023356846). Independent variables included regularity, change in frequency, and change in capability of different daily routines (i.e., physical activity, diet, sleep, social activities, leisure activities, work and studies, home activities, smoking, alcohol, combined multiple routines, unspecified generic routines). Dependent variables included symptoms and/or diagnoses of mental disorders (i.e., depression, anxiety, post-traumatic stress disorder, and general psychological distress). RESULTS: Fifty-three eligible studies (51 independent samples, 910,503 respondents) were conducted in five continents. Daily routine disruptions were positively associated with depressive symptoms (r = 0.13, 95% CI = [0.06; 0.20], p

ObjectiveThis study was undertaken to assess reproducibility of the epilepsy outcome and phenotype in a lateral fluid percussion model of posttraumatic epilepsy (PTE) across three study sites.MethodsA total of 525 adult male Sprague Dawley rats were randomized to lateral fluid percussion-induced brain injury (FPI) or sham operation. Of these, 264 were assigned to magnetic resonance imaging (MRI cohort, 43 sham, 221 traumatic brain injury [TBI]) and 261 to electrophysiological follow-up (EEG cohort, 41 sham, 220 TBI). A major effort was made to harmonize the rats, materials, equipment, procedures, and monitoring systems. On the 7th post-TBI month, rats were video-EEG monitored for epilepsy diagnosis.ResultsA total of 245 rats were video-EEG phenotyped for epilepsy on the 7th postinjury month (121 in MRI cohort, 124 in EEG cohort). In the whole cohort (n = 245), the prevalence of PTE in rats with TBI was 22%, being 27% in the MRI and 18% in the EEG cohort (p > .05). Prevalence of PTE did not differ between the three study sites (p > .05). The average seizure frequency was .317 ± .725 seizures/day at University of Eastern Finland (UEF; Finland), .085 ± .067 at Monash University (Monash; Australia), and .299 ± .266 at University of California, Los Angeles (UCLA; USA; p  .05). Of the 219 seizures, 53% occurred as part of a seizure cluster (≥3 seizures/24 h; p >.05 between the study sites). Of the 209 seizures, 56% occurred during lights-on period and 44% during lights-off period (p > .05 between the study sites).SignificanceThe PTE phenotype induced by lateral FPI is reproducible in a multicenter design. Our study supports the feasibility of performing preclinical multicenter trials in PTE to increase statistical power and experimental rigor to produce clinically translatable data to combat epileptogenesis after TBI.

Recent literature suggests that service dogs may be a valuable complementary intervention option for posttraumatic stress disorder (PTSD) among military veterans due to the potential influence on stress response dysregulation. The aim of this short-term longitudinal study was to quantify the impact of service dogs in US military veterans with PTSD with particular attention to the cortisol awakening response. A sub aim of the study was to empirically evaluate the physiological effects of PTSD service dogs on veteran partners. We conducted a clinical trial (ID: NCT03245814) that assessed the cortisol awakening response for 245 participants at baseline and 3 months follow-up across an intervention group (service dog: veterans n = 88, partners n = 46) and control group (usual care: n = 73, partners n = 38). A total of N = 161 veterans and N = 84 partners collected whole saliva samples via a passive drool collection immediately upon waking, 30 min after waking, and 45 min after waking on three consecutive weekdays at baseline and again at follow-up. Mixed model repeated measures (MMRM) with a fixed effect of the intervention group (service dog or control) were utilized. Covariates considered for the model included time of awakening, sleep duration, sleep efficiency, prior day experiences (measured via ecological momentary assessment), traumatic brain injury, age, gender, race, ethnicity, socioeconomic status, smoking status, alcohol use, physical health, and body mass index. A total of 3951 salivary samples were collected (veterans: 2613, partners: 1338). MMRM results demonstrated that veterans with a service dog had a statistically significant higher cortisol awakening response, including the area under the curve with respect to both increase (AUCi, β = 1.46, p = 0.046) and absolute increase (AINC, β = 0.05, p = 0.035). Results were not statistically significant for partners. Findings suggest that veterans with service dogs have a higher, less blunted CAR in comparison to veterans receiving usual care alone. In veterans with a blunted morning cortisol response, service dog placement could help boost their morning cortisol response.

Circulating cell-free mitochondrial DNA (ccf-mtDNA) is a biomarker of cellular injury or cellular stress and is a potential novel biomarker of psychological stress and of various brain, somatic, and psychiatric disorders. No studies have yet analyzed ccf-mtDNA levels in post-traumatic stress disorder (PTSD), despite evidence of mitochondrial dysfunction in this condition. In the current study, we compared plasma ccf-mtDNA levels in combat trauma-exposed male veterans with PTSD (n = 111) with those who did not develop PTSD (n = 121) and also investigated the relationship between ccf mt-DNA levels and glucocorticoid sensitivity. In unadjusted analyses, ccf-mtDNA levels did not differ significantly between the PTSD and non-PTSD groups (t = 1.312, p = 0.191, Cohens d = 0.172). In a sensitivity analysis excluding participants with diabetes and those using antidepressant medication and controlling for age, the PTSD group had lower ccf-mtDNA levels than did the non-PTSD group (F(1, 179) = 5.971, p = 0.016, partial η2 = 0.033). Across the entire sample, ccf-mtDNA levels were negatively correlated with post-dexamethasone adrenocorticotropic hormone (ACTH) decline (r = -0.171, p = 0.020) and cortisol decline (r = -0.149, p = 0.034) (viz., greater ACTH and cortisol suppression was associated with lower ccf-mtDNA levels) both with and without controlling for age, antidepressant status and diabetes status. Ccf-mtDNA levels were also significantly positively associated with IC50-DEX (the concentration of dexamethasone at which 50% of lysozyme activity is inhibited), a measure of lymphocyte glucocorticoid sensitivity, after controlling for age, antidepressant status, and diabetes status (β = 0.142, p = 0.038), suggesting that increased lymphocyte glucocorticoid sensitivity is associated with lower ccf-mtDNA levels. Although no overall group differences were found in unadjusted analyses, excluding subjects with diabetes and those taking antidepressants, which may affect ccf-mtDNA levels, as well as controlling for age, revealed decreased ccf-mtDNA levels in PTSD. In both adjusted and unadjusted analyses, low ccf-mtDNA levels were associated with relatively increased glucocorticoid sensitivity, often reported in PTSD, suggesting a link between mitochondrial and glucocorticoid-related abnormalities in PTSD.

The psychological states of hunger and satiety play an important role in regulating human food intake. Several lines of evidence suggest that these states rely upon declarative learning and memory processes, which are based primarily in the medial temporal lobes (MTL). The MTL, and particularly the hippocampus, is unusual in that it is especially vulnerable to insult. Consequently, we examine here the impact on hunger and satiety of conditions that: (1) are central to ingestive behaviour and where there is evidence of MTL pathology (i.e., habitual consumption of a Western-style diet, obesity, and anorexia nervosa); and (2) where there is overwhelming evidence of MTL pathology, but where ingestive behaviour is not thought central (i.e., temporal lobe epilepsy and post-traumatic stress disorder). While for some of these conditions the evidence base is currently limited, the general conclusion is that MTL impairment is linked, sometimes strongly, to dysfunctional hunger and satiety. This focus on the MTL, and declarative learning and memory processes, has implications for the development of alternative treatment approaches for the regulation of appetite.

Background: The impact on the physical and mental health of those who survived torture and their close circles in the Syrian regimes detention facilities remains under-studied.Objective: This qualitative study explored Syrian refugees narrations of captivity and torture, and the consequences of such extreme traumatic events on their physical and psychosocial health.Method: Thirteen audio-recorded interviews were conducted in Arabic with Syrian refugees. Study participants were at least 19 years of age, resided in diverse urban areas of Jordan, had experienced captivity and torture in Syrian detention facilities, and voluntarily agreed to participate in the study. Participation was anonymous, only oral consent was required, and no incentives were provided to participants. Interviews were transcribed and translated into English by a team of researchers, followed by analysis of repetitive themes according to the narrative paradigm.Results: Analysis of interviews elicited three major themes: extreme traumatic experiences of torture, and its physical and psychosocial health consequences. The first major theme was divided into two sub-themes: torture experienced by the participants themselves, and torture experienced by participants close circles. The second major theme, pertaining to physical health, was divided into two sub-themes: acute and chronic health sequelae. The third major theme, related to psychosocial health, was divided into four sub-themes: mental health symptomatology, impacts on professional life, impacts on interpersonal relationships, and social consequences.Conclusions: Torture experiences of Syrian refugees had adverse consequences for the physical and psychosocial health, functioning, and the overall well-being of survivors and their close circles. Interventions may seek to improve both the acute and chronic health consequences, as well as the mental health symptoms and associated impacts on livelihood, professional, and relationship dynamics. They should span clinical, legal, and advocacy spheres, given that a holistic approach may contribute immensely to survivors healing process.

Post-traumatic stress disorder (PTSD) may be a risk factor for Parkinsons disease (PD). We examined the relation between PTSD and PD in a cohort of 158,122 Veterans who had any Veterans Health Administration (VHA) or Medicare health care utilization between 10/1/1999- 2/17/2021. Using a nested case-control design we matched 10 controls to each Veteran with PD by sex, race, and rank. In conditional logistic regression models adjusted for camp and smoking, a PTSD diagnosis was significantly associated with PD (OR = 1.35; p = 0.0002); odds were higher if PTSD was coded before PD (OR = 1.53, p

Despite ample experimental data indicating a role of inflammatory mediators in the behavioral and neurobiological manifestations elicited by exposure to physical and psychologic stressors, causative associations between systemic low-grade inflammation and central nervous system inflammatory processes in posttraumatic stress disorder (PTSD) patients remain largely conceptual. As in other stress-related disorders, pro-inflammatory activity may play an equivocal role in PTSD pathophysiology, one that renders indiscriminate employment of anti-inflammatory agents of questionable relevance. In fact, as several pieces of preclinical and clinical research convergingly suggest, timely and targeted potentiation rather than inhibition of inflammatory responses may actually be beneficial in patients who are characterized by suppressed microglia function in the face of systemic low-grade inflammation. The deleterious impact of chronic stress-associated inflammation on the systemic level may, thus, need to be held in context with the - often not readily apparent - adaptive payoffs of low-grade inflammation at the tissue level.

BackgroundTraumatic brain injury (TBI) and posttraumatic stress disorder (PTSD) are potential risk factors for the development of dementia including Alzheimer's disease (AD) in later life. The findings of studies investigating this question are inconsistent though.ObjectiveTo investigate if these inconsistencies are caused by the existence of subgroups with different vulnerability for AD pathology and if these subgroups are characterized by atypical tau load/atrophy pattern.MethodsThe MRI and PET data of 89 subjects with or without previous TBI and/or PTSD from the DoD ADNI database were used to calculate an age-corrected gray matter tau mismatch metric (ageN-T mismatch-score and matrix) for each subject. This metric provides a measure to what degree regional tau accumulation drives regional gray matter atrophy (matrix) and can be used to calculate a summary score (score) reflecting the severity of AD pathology in an individual.ResultsThe ageN-T mismatch summary score was positively correlated with whole brain beta-amyloid load and general cognitive function but not with PTSD or TBI severity. Hierarchical cluster analysis identified five different spatial patterns of tau-gray matter interactions. These clusters reflected the different stages of the typical AD tau progression pattern. None was exclusively associated with PTSD and/or TBI.ConclusionsThese findings suggest that a) although subsets of patients with PTSD and/or TBI develop AD-pathology, a history of TBI or PTSD alone or both is not associated with a significantly higher risk to develop AD pathology in later life. b) remote TBI or PTSD do not modify the typical AD pathology distribution pattern.

ObjectiveProject 1 of the Preclinical Multicenter Epilepsy Bioinformatics Study for Antiepileptogenic Therapy (EpiBioS4Rx) consortium aims to identify preclinical biomarkers for antiepileptogenic therapies following traumatic brain injury (TBI). The international participating centers in Finland, Australia, and the United States have made a concerted effort to ensure protocol harmonization. Here, we evaluate the success of harmonization process by assessing the timing, coverage, and performance between the study sites.MethodWe collected data on animal housing conditions, lateral fluid-percussion injury model production, postoperative care, mortality, post-TBI physiological monitoring, timing of blood sampling and quality, MR imaging timing and protocols, and duration of video-electroencephalography (EEG) follow-up using common data elements. Learning effect in harmonization was assessed by comparing procedural accuracy between the early and late stages of the project.ResultsThe animal housing conditions were comparable between the study sites but the postoperative care procedures varied. Impact pressure, duration of apnea, righting reflex, and acute mortality differed between the study sites (p  0.05). Plasma quality was poor in 4% of the samples in UEF, 1% in Monash and 14% in UCLA. More than 97% of the final cohort were MR imaged at all timepoints in all study sites. The timing of imaging did not differ on D2 and D9 (p > 0.05), but varied at D30, 5 months, and ex vivo timepoints (p  0.05). A decrease in acute mortality and increase in plasma quality across time reflected a learning effect in the TBI production and blood sampling protocols.SignificanceOur study is the first demonstration of the feasibility of protocol harmonization for performing powered preclinical multi-center trials for biomarker and therapy discovery of post-traumatic epilepsy.

INTRODUCTION: There is a resurgence of interest in the therapeutic potential of psychedelic substances such as 3,4-methylenedioxymethamphetamine (MDMA). Primary findings from our randomized, double-blind, placebo-controlled, multi-site Phase 3 clinical trial of participants with severe PTSD (NCT03537014) showed that MDMA-assisted therapy induced significant attenuation in the Clinician-Administered PTSD Scale for DSM-5 compared to Therapy with placebo. Deficits in emotional coping skills and altered self-capacities constitute major obstacles to successful completion of available treatments. The current analysis evaluated the differential effects of MDMA-assisted therapy and Therapy with placebo on 3 transdiagnostic outcome measures and explored the contribution of changes in self-experience to improvement in PTSD scores. METHODS: Participants were randomized to receive manualized therapy with either MDMA or placebo during 3 experimental sessions in combination with 3 preparation and 9 integration therapy visits. Symptoms were measured at baseline and 2 months after the last experimental session using the 20-item Toronto Alexithymia Scale (TAS-20), the 26-item Self Compassion Scale (SCS), and the 63-item Inventory of Altered Self-Capacities (IASC). RESULTS: 90 participants were randomized and dosed (MDMA-assisted therapy, n = 46; Therapy with placebo, n = 44); 84.4% (76/90) had histories of developmental trauma, and 87.8% (79/90) had suffered multiple traumas. MDMA-assisted therapy facilitated statistically significant greater improvement on the TAS-20, the SCS, and most IASC factors of interpersonal conflicts; idealization disillusionment; abandonment concerns; identity impairment; self-awareness; susceptibility to influence; affect dysregulation; affect instability; affect skill deficit; tension reduction activities; the only exception was identity diffusion. CONCLUSION: Compared with Therapy with placebo, MDMA-assisted therapy had significant positive effects on transdiagnostic mental processes of self-experience which are often associated with poor treatment outcome. This provides a possible window into understanding the psychological capacities facilitated by psychedelic agents that may result in significant improvements in PTSD symptomatology.

The Russian-Ukrainian war (RUW) is responsible for extensive individual suffering and a socio-economic impact on the world and is reshaping global affairs. Many studies have focused on direct exposure to conflict and several public health policies have been devised. Nonetheless, indirect exposure through media has received minimal attention and there is limited evidence that mental health symptoms and disorders may arise as a result. We explored the role of voluntary or involuntary media-based exposure to the RUW on individuals' mental health including stress symptoms, coping strategies, daily functioning, and worries across demographic variables. In our sample, subjects with involuntary and higher amount of exposure seem to have higher stress symptoms. Also, those who had previous ruminations on war issues could be at risk of developing more post-traumatic stress symptoms. Therefore, media appears to be a conduit that spreads negative consequences of community trauma beyond directly affected communities. [ABSTRACT FROM AUTHOR]

Background: India is home to 14 million survivors of human trafficking, with most being trafficked for sexual exploitation. Trafficking constitutes crimes that violate the rights of survivors, and despite its psychological consequences, there is little evidence-based guidance to meet the needs of these individuals. Aim: The current study aimed to examine the outcome of narrative exposure therapy (KIDNET) among adolescent survivors of sex trafficking in improving trauma-related symptoms, along with psychological distress, dissociation, depression, and anxiety. Methods: A pre-post study design was used with 20 adolescent female survivors of trafficking aged 13 to 17 years, with ten participants in the KIDNET group and ten participants in a waitlist control group. Trafficking Victim Identification Tool and Standard Progressive Matrices were administered as screening measures. The Clinician-Administered PTSD Scale for Children and Adolescents, Kessler's Psychological Distress Scale, Shutdown Dissociation Scale, Patient Health Questionnaire, and Beck Anxiety Inventory were administered as outcome measures. Fourteen sessions of KIDNET were conducted for the clinical group, while sessions were conducted for the control group post delivery of intervention for the clinical group. Results: Findings suggest an overall improvement in the severity of trauma-related symptoms in the KIDNET group, with significant improvement in psychological distress, depression, and anxiety. Conclusion: Results indicate that KIDNET may be a promising and acceptable treatment for adolescent survivors of sex trafficking, and this intervention module may be safely delivered in further randomised controlled trials to ensure that the holistic needs of this vulnerable group are appropriately addressed.

To determine factors that are associated with the presence and severity of radiologically confirmed knee osteoarthritis (OA) two years after anterior cruciate ligament reconstruction (ACLR). Forty-one athletes with two years of ACLR participated in the study and completed the International Knee Documentation Committee 2000 (IKDC2000)and knee injury and osteoarthritis outcome score (KOOS) questionnaires. Limb-to-limb knee ROM differences were measured. Athletes completed knee radiographs. Medial- and lateral-compartment-OA were graded using Kellgren-Lawrence (KL) grades (Non-OA group (KL:≤1), OA group (KL:≥2; moderate (KL:2); severe (KL:3,4)). Medial-compartment-OA was found in 31.7% of athletes (Moderate:17.1%, Severe:14.6%) and lateral-compartment-OA in 19.5% (Moderate:12.2%, severe:7.3%). Age (r = 0.306) and BMI (r = 0.382) (p ≤ 0.014) correlated with medial-compartment-OA; while age (r = 0.433), BMI (r = 0.388), meniscus injury (r = 0.378), and injury-to-surgery time (r:0.376) (p ≤ 0.022) correlated with severe medial-compartment-OA. KOOS-Sport/Recreation (r = −0.386), IKDC 2000 (r = −0.343), and knee flexion ROM (r = −0.343) (p = 0.014) correlated with lateral-compartment-OA, while KOOS-Sport/Recreation (r = −0.376, p = 0.017) correlated with severe lateral-compartment-OA. Older athletes and high BMI were associated with medial-compartment-OA, while older athletes, high BMI, longer injury-to-surgery duration, and having a meniscus injury were associated with severe medial-compartment-OA. Lower KOOS-Sport/Recreation and IKDC2000 scores, and knee flexion ROM were associated with lateral-compartment-OA, while low KOOS-Sport/Recreation score was associated with severe lateral-compartment-OA. • Old age and high BMI were associated with knee OA at the medial compartment. • Old age, high BMI, late surgery, and meniscus injury associated with severe knee OA at the medial compartment. • Low KOOS-sport and IKDC2000 scores and knee flexion ROM associated with knee OA at the lateral compartment. • Low KOOS-sport score was associated with severe knee OA at the lateral compartment.

Abstract Background Synostosis refers to the abnormal fusion of bones, which have varying aetiologies as well as sites which are commonly affected. Existing literature mostly describes the condition arising congenitally, and affecting the radio-ulnar joint. Case presentation A 57-year-old gentleman presented to our department with symptomatic malunion and synostosis of the fourth and fifth metatarsals, two years following non-operative treatment of a closed fifth metatarsal fracture. The patient subsequently underwent surgical excision of the synostosis, but had complications of recurrence at the two-year post-operative date. Repeat surgical excision was performed with eventual good functional outcome and no signs of recurrence. Conclusion Our paper aims to describe the first known case of post-traumatic synostosis affecting the metatarsals, as well as provide a review of the current literature.

Childhood trauma is a known risk factor for trauma and stress-related disorders in adulthood. However, limited research has investigated the impact of childhood trauma on brain structure linked to later posttraumatic dysfunction. We investigated the effect of childhood trauma on white matter microstructure after recent trauma and its relationship with future posttraumatic dysfunction among trauma-exposed adult participants (n = 202) recruited from emergency departments as part of the AURORA Study. Participants completed self-report scales assessing prior childhood maltreatment within 2-weeks in addition to assessments of PTSD, depression, anxiety, and dissociation symptoms within 6-months of their traumatic event. Fractional anisotropy (FA) obtained from diffusion tensor imaging (DTI) collected at 2-weeks and 6-months was used to index white matter microstructure. Childhood maltreatment load predicted 6-month PTSD symptoms (b = 1.75, SE = 0.78, 95% CI = [0.20, 3.29]) and inversely varied with FA in the bilateral internal capsule (IC) at 2-weeks (p = 0.0294, FDR corrected) and 6-months (p = 0.0238, FDR corrected). We observed a significant indirect effect of childhood maltreatment load on 6-month PTSD symptoms through 2-week IC microstructure (b = 0.37, Boot SE = 0.18, 95% CI = [0.05, 0.76]) that fully mediated the effect of childhood maltreatment load on PCL-5 scores (b = 1.37, SE = 0.79, 95% CI = [-0.18, 2.93]). IC microstructure did not mediate relationships between childhood maltreatment and depressive, anxiety, or dissociative symptomatology. Our findings suggest a unique role for IC microstructure as a stable neural pathway between childhood trauma and future PTSD symptoms following recent trauma. Notably, our work did not support roles of white matter tracts previously found to vary with PTSD symptoms and childhood trauma exposure, including the cingulum bundle, uncinate fasciculus, and corpus callosum. Given the IC contains sensory fibers linked to perception and motor control, childhood maltreatment might impact the neural circuits that relay and process threat-related inputs and responses to trauma.

Adolescents involved in juvenile legal system are at increased risk for self-cutting behavior, however, correlates associated with elevated risk remain underresearched, particularly among youth with first involvement with the court. This study utilized an epidemiological two-year longitudinal study involving 401 adolescents at first contact with the court (Mage = 14.47; SDage = 1.94 years; 43% female; 42% Latinx/Hispanic) and an involved caregiver. Study aims examined key prospective psychosocial correlates of self-cutting behavior. Baseline assessments captured individual and family level risk and protective factors; self-cutting behavior was assessed longitudinally every four months post-baseline for 24 months. Psychosocial correlates of self-cutting behavior included adolescent affect dysregulation, post-traumatic stress disorder symptoms, impulsive decision making, anxiety and depression symptoms. Significant protective factors included positive communication with caregiver and family, higher self-esteem, and having a caring and supportive family. These findings suggest that internalizing symptoms as well as difficulties with emotion regulation and impulsive decision making are correlated with heightened risk for self-cutting behavior among adolescents involved in the juvenile legal system. The findings also suggest that individual and family level protective factors, like positive communication and a supportive family, are associated with decreased risk for self-cutting behavior among adolescents at first contact with the court.

BACKGROUND: Recent advances in data-driven computational approaches have been helpful in devising tools to objectively diagnose psychiatric disorders. However, current machine learning studies limited to small homogeneous samples, different methodologies, and different imaging collection protocols, limit the ability to directly compare and generalize their results. Here we aimed to classify individuals with PTSD versus controls and assess the generalizability using a large heterogeneous brain datasets from the ENIGMA-PGC PTSD Working group. METHODS: We analyzed brain MRI data from 3,477 structural-MRI; 2,495 resting state-fMRI; and 1,952 diffusion-MRI. First, we identified the brain features that best distinguish individuals with PTSD from controls using traditional machine learning methods. Second, we assessed the utility of the denoising variational autoencoder (DVAE) and evaluated its classification performance. Third, we assessed the generalizability and reproducibility of both models using leave-one-site-out cross-validation procedure for each modality. RESULTS: We found lower performance in classifying PTSD vs. controls with data from over 20 sites (60 % test AUC for s-MRI, 59 % for rs-fMRI and 56 % for d-MRI), as compared to other studies run on single-site data. The performance increased when classifying PTSD from HC without trauma history in each modality (75 % AUC). The classification performance remained intact when applying the DVAE framework, which reduced the number of features. Finally, we found that the DVAE framework achieved better generalization to unseen datasets compared with the traditional machine learning frameworks, albeit performance was slightly above chance. CONCLUSION: These results have the potential to provide a baseline classification performance for PTSD when using large scale neuroimaging datasets. Our findings show that the control group used can heavily affect classification performance. The DVAE framework provided better generalizability for the multi-site data. This may be more significant in clinical practice since the neuroimaging-based diagnostic DVAE classification models are much less site-specific, rendering them more generalizable.

BACKGROUND: Regularizing bedtime and out-of-bed times is a core component of behavioral treatments for sleep disturbances common among patients with posttraumatic stress disorder (PTSD). Although improvements in subjective sleep complaints often accompany improvements in PTSD symptoms, the underlying mechanism for this relationship remains unclear. Given that night-to-night sleep variability is a predictor of physical and mental well-being, the present study sought to evaluate the effects of bedtime and out-of-bed time variability on daytime affect and explore the optimal window lengths of over which variability is calculated. METHODS: For about 30 days, male U.S. military veterans with PTSD (N = 64) in a residential treatment program provided ecological momentary assessment data on their affect and slept on beds equipped with mattress actigraphy. We computed bedtime and out-of-bed time variability indices with varying windows of days. We then constructed multilevel models to account for the nested structure of our data and evaluate the impact of bedtime and out-of-bed time variability on daytime affect. RESULTS: More regular bedtime across 6-9 days was associated with greater subsequent positive affect. No similar effects were observed between out-of-bed time variability and affect. CONCLUSIONS: Multiple facets of sleep have been shown to differently predict daily affect, and bedtime regularity might represent one of such indices associated with positive, but not negative, affect. A better understanding of such differential effects of facets of sleep on affect will help further elucidate the complex and intertwined relationship between sleep and psychopathology. TRIAL REGISTRATION: The trial retrospectively was registered on the Defense Technical Information Center website: Award # W81XWH-15-2-0005.

Patients exposed to trauma often experience high rates of adverse post-traumatic neuropsychiatric sequelae (APNS). The biological mechanisms promoting APNS are currently unknown, but the microbiota-gut-brain axis offers an avenue to understanding mechanisms as well as possibilities for intervention. Microbiome composition after trauma exposure has been poorly examined regarding neuropsychiatric outcomes. We aimed to determine whether the gut microbiomes of trauma-exposed emergency department patients who develop APNS have dysfunctional gut microbiome profiles and discover potential associated mechanisms. We performed metagenomic analysis on stool samples (n = 51) from a subset of adults enrolled in the Advancing Understanding of RecOvery afteR traumA (AURORA) study. Two-, eight- and twelve-week post-trauma outcomes for post-traumatic stress disorder (PTSD) (PTSD checklist for DSM-5), normalized depression scores (PROMIS Depression Short Form 8b) and somatic symptom counts were collected. Generalized linear models were created for each outcome using microbial abundances and relevant demographics. Mixed-effect random forest machine learning models were used to identify associations between APNS outcomes and microbial features and encoded metabolic pathways from stool metagenomics. Microbial species, including Flavonifractor plautii, Ruminococcus gnavus and, Bifidobacterium species, which are prevalent commensal gut microbes, were found to be important in predicting worse APNS outcomes from microbial abundance data. Notably, through APNS outcome modeling using microbial metabolic pathways, worse APNS outcomes were highly predicted by decreased L-arginine related pathway genes and increased citrulline and ornithine pathways. Common commensal microbial species are enriched in individuals who develop APNS. More notably, we identified a biological mechanism through which the gut microbiome reduces global arginine bioavailability, a metabolic change that has also been demonstrated in the plasma of patients with PTSD.

INTRODUCTION: Patients with mental health disorders are at risk for receiving inequitable cancer treatment, likely resulting from various structural, social, and health-related factors. This study aims to assess the relationship between mental health disorders and the use of definitive treatment in a population-based cohort of those with localized, clinically significant prostate cancer. METHODS: We conducted a cohort study analysis in SEER (Surveillance, Epidemiology, and End Results)-Medicare (2004-2015). History of a mental health disorder was defined as presence of specific ICD (International Classification of Diseases)-9 or ICD-10 diagnostic codes in the 2 years preceding cancer diagnosis. Descriptive statistics were performed using Wilcoxon rank-sum and χ2 testing. Multivariable logistic regression was used to evaluate the relationship between mental health disorders and definitive treatment utilization (defined as surgery or radiation). RESULTS: Of 101,042 individuals with prostate cancer, 7,945 (7.8%) had a diagnosis of a mental health disorder. They were more likely to be unpartnered, have a lower socioeconomic status, and less likely to receive definitive treatment (61.8% vs 68.2%, P < .001). Definitive treatment rates were >66%, 62.8%, 60.3%, 58.2%, 54.3%, and 48.1% for post-traumatic stress disorder, depressive disorder, bipolar disorder, anxiety disorder, substance abuse disorder, and schizophrenia, respectively. After adjusting for age, race and ethnicity, marital status and socioeconomic status, history of a mental health disorder was associated with decreased odds of receiving definitive treatment (OR 0.74, 95% CI 0.66-0.83). CONCLUSIONS: Individuals with mental health disorders and prostate cancer represent a vulnerable population; careful attention to clinical and social needs is required to support appropriate use of beneficial treatments.

UNLABELLED: [Correction Notice: An Erratum for this article was reported online in Psychological Trauma: Theory, Research, Practice, and Policy on Jun 30 2022 (see record 2022-76274-001). In the original article, the following acknowledgment of funding was missing from the title page author note: This material was based upon work supported by the United States Department of Veterans Affairs (VA), Veterans Health Administration, Patient Care Services, Health Outcomes Military Exposures Epidemiology Program as well as two VA Health Services Research and Development Service Grants Validation of Modified DRRI Scales in a National Sample of OEF/OIF Veterans (Project DHI 09-086, Dawne Vogt, Principal Investigator) and Work and Family Functioning in Women Veterans: Implications for VA Service Use (Project IIR 12-345, Dawne Vogt and Brian N. Smith, Principal Investigators). All versions of this article have been corrected.] Objective: It is important to assess warfare experiences beyond direct combat exposure, as these exposures can negatively impact military veterans health. Although two validated scales from the Deployment Risk and Resilience Inventory-2 [DRRI-2] together capture a broad range of stressful warfare experiences, the length of this combined measure (30 items) is prohibitively long for some settings. Therefore, the goal of this project was to develop and validate a short form Warfare Exposure measure (DRRI-2-WE-SF). METHOD: U.S. veterans deployed for the wars in Iraq and Afghanistan completed questionnaires across 2 studies (study 1, N = 1046; study 2, N = 7141) to develop and validate the DRRI-2 WE-SF. RESULTS: Study 1 involved developing the DRRI-2 WE-SF, a 9-item self-report instrument with strong internal consistency (α = .86) and large correlations with the full Warfare Exposure measure (r = .97). In study 2, the DRRI-2 WE-SF again demonstrated high levels of reliability and validity and evidenced high levels of classification accuracy (89.7% correct classification) and significant time savings (all ts > 39; all ps < .05) in comparison to the full measure. CONCLUSIONS: The DRRI-2 WE-SF is a psychometrically sound measure of direct exposures to warfare and its consequences. This measure of proximal warfare exposure retains the strong properties of the full measure while significantly reducing completion time. These properties make the DRRI-2 WE-SF a useful tool for efficiently evaluating proximal warfare exposure among individuals who have served in both combat and noncombat roles.

Objectives: This study assessed the prevalence and correlates of post-traumatic stress disorder (PTSD) among internally displaced people (IDP) in the Qoloji Camp, Somali Regional State, Eastern Ethiopia. Methods: A community-based cross-sectional study was conducted from October 20 to November 5, 2021. The study utilized systematic random sampling to identify 410 IDP participants from the Qoloji Camp. PTSD was measured using the PTSD Check-list for DSM-5 (PCL-5). Bivariate analysis was performed to determine the crude odds ratio, and multivariate analysis was used to calculate adjusted odds ratios for associations between PTSD and independent variables. Results: A total of 404 participants were interviewed (98.5% response rate). The estimated prevalence of PTSD symptoms was 41.1%. In the multivariate logistic regression analysis, several factors were significantly associated with PTSD: being female (AOR = 2.5, 95% CI = 1.39-4.44), lack of food and water (AOR = 2.2, 95% CI = 1.17, 4.23), destruction of personal property (AOR = 3.1, 95% CI = 1.62-6.09), and experiencing torture or beatings (AOR = 1.8, 95% CI = 1.01‐3.28). Conclusion: This study found a high prevalence of PTSD symptoms among IDPs, with factors such as female sex, property destruction, deprivation of essential goods and services, and experiences of torture or beatings significantly associated with those symptoms. To address these findings, prioritizing the well-being of IDPs with a specific focus on women, on-site screening, and the establishment of a referral system to facilitate access to specialized care are essential to enhance the overall mental health of such persons.

Background: Given the inherent nature of their job, law enforcement staff regularly confront major stressors. Objectives: The prevalence of post-traumatic stress disorder (PTSD) among law enforcement staff is about twice that of the general population. We conducted this study to assess PTSD risk factors among this population. Methods: This prospective case-control study was conducted on patients with PTSD working as law enforcement staff as the case group, and their comrades with no PTSD as the control group. We used a questionnaire, including possible factors contributing to the development of PTSD, to gather the data. Binomial logistic regression was used to calculate the odds ratio (OR) and 95% confidence intervals. Results: A total of 84 participants were included in the study. We found that some factors could be protective against PTSD, including marriage (OR: 0.270, 95% CI: 0.087 - 0.839, P-value: 0.024), having an academic degree (OR: 0.333, 95% CI: 0.114 - 0.978, Pvalue: 0.045), higher income (R2: 0.081; OR: 0.849, 95% CI: 0.721 - 1.000, P-value: 0.050), and receiving satisfactory family support (OR: 0.413, 95% CI: 0.171 - 0.999, P-value: 0.050). Furthermore, logistic regression showed that a positive psychological history (OR: 2.562, 95% CI: 1.025 - 6.406, P-value: 0.044), a positive familial psychological history (OR: 2.667, 95% CI: 1.099 - 6.406, P-value: 0.030), and encountering trauma (aside from the current trauma) after 18 years of age (OR: 2.643, 95% CI: 1.038 - 6.731, P-value: 0.041) are risk factors for PTSD. Conclusions: Our results showed that marriage, having an academic degree, higher income, and receiving satisfactory family support are protective factors. In addition, the risk factors for PTSD include a positive psychological history, a positive familial psychological history, and encountering trauma (aside from the current trauma) after 18 years of age. However, given our limitations, further studies should be conducted before drawing solid conclusions. [ABSTRACT FROM AUTHOR]

Objectives: This study aimed, following both single‐ and multi‐event trauma, to ascertain prevalence and course of the dissociative subtype of post‐traumatic stress disorder (PTSD‐DS) in youth; how well early PTSD‐DS predicts later PTSD; and whether dissociation accounts for unique variance in post‐traumatic stress symptoms (PTSS) and functional impairment over and above the effect of other post‐trauma cognitive processing factors and PTSS respectively. Design and Methods: This study is a secondary analysis of data from the Acute Stress Programme for Children and Teenagers study (n = 234) and the Coping in Care After Trauma study (n = 110) in which children had experienced single‐ and multi‐event trauma respectively. Results: PTSD‐DS diagnosis was common in children with PTSD regardless of trauma experienced (>39.0%). PTSD‐DS showed a similar trajectory of natural recovery to PTSD, and it was similarly predictive of later PTSD following single‐event trauma. Finally, dissociation was a significant factor in PTSS and functional impairment. Conclusions: These results should be viewed in the context of several limitations including narrow sample of participants which reduces the generalizability of results, concerns around children's ability to conceptualize challenging concepts such as dissociation and the use of self‐report measures to form diagnostic groups. The PTSD‐DS diagnosis may offer clinical utility to the extant PTSD diagnosis in children and adolescents, as dissociation has been shown to be a contributory factor in the maintenance of both PTSS and functional impairment. Further research is required to inform further editions of the DSM and other diagnostic systems. [ABSTRACT FROM AUTHOR]

Post-traumatic cerebral venous sinus thrombosis (ptCVST) often remains underdiagnosed due to the non-specific nature of clinical signs, commonly mimicking severe traumatic brain injury (TBI) manifestations. Early recognition of this rare and potentially life-threatening complication is crucial for the effective management of severe TBI patients in Intensive Care. The present study reports the case of a 66-year-old male who was transferred to the emergency department due to moderate TBI. Initial emergency brain computed tomography (CT) scans revealed certain traumatic lesions, not necessitating any urgent neurosurgical intervention. During his stay in an Intensive Care Unit (ICU), multiple transient episodes of intracranial pressure (ICP) values were managed conservatively, and through placement of an external ventricular drain. Following a series of CT scans, there was a continuous improvement of the initial traumatic hemorrhagic findings despite his worsening clinical condition. This paradox raised suspicion for ptCVST, and a brain CT venography (CTV) was carried out, which showed venous sinus thrombosis close to a concomitant skull fracture. Therapeutic anticoagulant treatment was administered. The patient was discharged with an excellent neurological status. To date, there are no clearly defined guidelines for medical and/or surgical management of patients presenting with ptCVST. Therapy is mainly based on intracranial hypertension control and the maintenance of normal cerebral perfusion pressure (CCP) in the ICU. The mismatch between clinical and imaging findings in patients with TBI and certain risk factors raises the suspicion of ptCVST. [ABSTRACT FROM AUTHOR]

Despite the increased heterogeneity of living conditions of refugees in recent years, there is a lack of robust epidemiological data about the relationship between refugees' mental health and their living contexts. The current study aims to compare frequencies of pre-migration traumatic events and post-migration difficulties between refugees living in camps and those living in cities; and to identify the prevalence of post-traumatic stress disorder (PTSD), depression, and factors associated with them. A field survey was conducted among 1,470 refugees living in camps and urban settings of Turkey. The survey instruments included a socio-demographic form, the Harvard Trauma Questionnaire, the Post-migration Living Difficulties Scale, and the PTSD and depression modules of the Mini-International Neuropsychiatric Interview. Both PTSD and depression were more common in urban settings than in camps. Both disorders were associated with living context and migration-related experiences. Pre-migration traumas were more frequent among refugees living in cities than in those living in camps, while post-migration difficulties were more common in the refugees living in camps. The living context is potentially a critical determinant of refugee mental health. Camp and urban refugees may have different experiences and needs. In particular, refugees living in some urban settings may be at higher risk for having psychological problems. [ABSTRACT FROM AUTHOR]

Post-traumatic stress disorder represents a multifaceted clinical entity with a profound impact on mental health. This study was conducted to evaluate the effects of cognitive analytic therapy on the manifestations of post-traumatic stress disorder. From May 21, 2023, to July 7, 2023, we conducted a randomized control trial in the outpatient clinic of a psychiatry Hospital. Participants were Iran-Iraq war veterans (N = 40) with a confirmed diagnosis of post-traumatic stress disorder. They were randomly allocated to cognitive analytic therapy and control groups. The primary outcome was re-experiencing, and the secondary outcomes included avoidance, hyperarousal, depression, anxiety, and numbness scores measured by appropriate questionnaires before and after the interventions. The cognitive analytic therapy group received a weekly program totaling 12 sessions of therapy adjunct to pharmacotherapy, each session lasting 90 min, and the control group received only pharmacotherapy. Within-group analysis showed that cognitive analytic therapy (N = 19) decreased all symptom scores (all p < 0.001), while the control group (N = 20) showed a decrease in hyper-arousal, depression, and anxiety (p < 0.001) scores. Between-group analysis implied that cognitive analytic therapy was more successful than usual pharmacotherapy in decreasing all outcome scores (all p < 0.001) A 12-session program of cognitive analytic therapy was effective in alleviating re-experiencing, avoidance, hyper-arousal, depression, anxiety, and numbness in post-traumatic stress disorder. It was safe and acceptable by participants reflected by a high retention rate. We recommend the incorporation of cognitive analytic therapy to the treatment of post-traumatic stress disorder. A 12-session of CAT is effective for treating PTSD. The interventions control re-experiencing, avoidance, and hyper-arousal in PTSD. Also, they decrease depression, anxiety, and numbness in patients with PTSD. Overall, CAT is safe and acceptable to participants. Participants' retention is high for CAT with a minimum dropout.

Aims: This study is designed to generalize and depict the research hotspots of endophthalmitis through bibliometric methods and software and analyze the evolutive tendency of the work on this severe disease over the past 30 years. Methods: This study employed a rigorous bibliometric approach. We identified all endophthalmitis-related literature by conducting a comprehensive search of the Science Citation Index Expanded database under the Web of Science Core Collection. The data was then analyzed and visualized using CiteSpace and VOSviewer, two widely recognized software tools in the field of bibliometrics. CiteSpace was used to analyze the country distributions, dual map overlay of journals, keyword bursts, and co-cited references. VOSviewer was employed to describe the authors and co-cited authors, the journals, the co-cited journals, and the keywords co-occurrence network. This robust methodology ensures the reliability and validity of the study's findings. Results: A total of 2960 publications, including 2695 articles and 265 reviews, were included in this bibliometric study. There has been no shortage of endophthalmitis-related publications since 1993, with an apparent upward trend during recent years. Possible correlations with the COVID-19 pandemic are also analyzed. These studies were finished by 11,048 authors from 75 countries worldwide, with the United States in the lead. In the keyword cooccurrence network, except for the endophthalmitis term, cataract surgery becomes the keyword with the highest frequency. Different categories of endophthalmitis, including postoperative, post-injection, post-traumatic, and endogenous endophthalmitis, and antibacterial and anti-inflammatory therapies of infectious endophthalmitis, are discussed by categories. From the perspective of the timeline, postoperative and post-injection endophthalmitis were the dominant forms before and after the year 2000, respectively. Cocitation analyses reveal that the Endophthalmitis Vitrectomy Study (EVS) conducted in 1995 provides pivotal guidance for later research. Diverse pathogenic bacteria (e.g., Coagulase-negative Staphylococci, Propionibacterium acnes, Viridians Streptococci, and Bacillus cereus) or fungi (e.g., Candida, Aspergillus, and Fusarium) contribute to varying treatment principles and clinical prognosis, which should be taken seriously. In addition, intravitreal and intracameral antibiotics are the mainstay for treating and preventing infectious endophthalmitis, respectively. Conclusion: Our bibliometric analysis provides an overview of dynamic evolution and structural relationships in the research field of endophthalmitis. The displayed hotspots and developmental directions have reference values for future investigation. [ABSTRACT FROM AUTHOR]

Background: This study aimed to investigate the effects of CPT on PTSD, depression, and anxiety symptoms in female victims of domestic violence. Method: A two-arm randomized clinical trial was conducted in Bandar-Abbas involving 62 female victims of domestic violence referred from private gynecology and obstetrics clinics. Initial screening for domestic violence was based on the World Health Organization violence questionnaire. Participants were randomly assigned to either a control group (n=32) or an intervention group (n=28) for a study duration of six months in 2022. Twelve group CPT sessions were conducted. The domestic violence questionnaire, Beck's Depression Inventory, Beck's A nxiety Inventory, and the Impact of Event Scale-Revised were completed in three time points: pre-test, post-test, and follow-up. Results: There was a statistically significant difference in the mean scores of depression, PTSD, and domestic violence (P less than .001) between the two groups; however, no significant difference was found in anxiety scores (P greater than .050). Conclusion: CPT is recommended for female victims of domestic violence to reduce symptoms of depression, PTSD, and domestic violence. [ABSTRACT FROM AUTHOR]

Background: Revision of radial head arthroplasty (RHA) may be indicated in cases of prosthesis loosening and malposition. Inherent difficulties in revision surgery include poor bone stock and disrupted soft tissue envelope. Although cases of RHA used for revision of failed RHA are rare, there is reasonable expectation for increasing frequency of these cases due to the increasing incidence of primary RHA. Furthermore, there is an increasing demand for postoperative recovery of function; thus, surgeons may consider revising a failed RHA to a new RHA. We report on series of failed RHA which were revised to a new radial head prosthesis. Methods: A retrospective review was performed at multiple institutions for a single radial head prosthesis used for revision of a failed radial head prosthesis. Clinical and radiographic outcomes were collected with a minimum of 1 year of follow-up. Results: Across 11 patients at a mean follow-up of 45.1 months, the mean Mayo Elbow Performance Score was 81.7; mean Disabilities of the Arm, Shoulder, and Hand scores were 24.4; and mean Visual Analog Scale for pain was 0.6. Radiographic analysis yielded no evidence of capitellar wear or stem loosening. Conclusion: A radial head prosthesis can produce satisfactory results when used for revision of a failed prosthesis. Inherent difficulties in revision surgery include the potential for reduced bone stock and a disrupted soft tissue envelope. Elements of prosthesis design which may contribute to effectively managing revision surgery include a long stem with in-growth surface and prosthetic head alignment to the axis of forearm rotation.

Our systematic review aimed to investigate the prevalence of post-traumatic stress symptoms (PTSS) and post-traumatic stress disorder (PTSD) among parents within 12 months of their child's burn injury. A literature search was conducted in PubMed, Embase, Web of Science, Psychinfo, and CINAHL on January 6, 2023, for quantitative studies reporting the prevalence of PTSD and/or PTSS in parents within 12 months following their child's burn injury. The risk of bias was assessed using the Mixed Methods Appraisal Tool version 2018. A narrative synthesis of prevalence was presented. We identified 15 articles that met our inclusion criteria. The prevalence of PTSS within 12 months following the burn injury ranged from 6% to 49%. Prevalence estimates of PTSD within the 12 months following a burn injury were limited, ranging from 4.4% to 22%. Our findings highlight the significant impact of burn injuries on parental mental health, with a considerable proportion of parents experiencing PTSS within 12 months following their child's burn injury. Prevalence estimates for PTSD were limited and warrant further investigation. Our review also underscores the need for standardization of PTSS/PTSD terminology. Timely and targeted psychological support is needed for parents in the aftermath of their child's burn injury. [ABSTRACT FROM AUTHOR]

Preclinical MRI studies have been utilized for the discovery of biomarkers that predict post-traumatic epilepsy (PTE). However, these single site studies often lack statistical power due to limited and homogeneous datasets. Therefore, multisite studies, such as the Epilepsy Bioinformatics Study for Antiepileptogenic Therapy (EpiBioS4Rx), are developed to create large, heterogeneous datasets that can lead to more statistically significant results. EpiBioS4Rx collects preclinical data internationally across sites, including the United States, Finland, and Australia. However, in doing so, there are robust normalization and harmonization processes that are required to obtain statistically significant and generalizable results. This work describes the tools and procedures used to harmonize multisite, multimodal preclinical imaging data acquired by EpiBioS4Rx. There were four main harmonization processes that were utilized, including file format harmonization, naming convention harmonization, image coordinate system harmonization, and diffusion tensor imaging (DTI) metrics harmonization. By using Python tools and bash scripts, the file formats, file names, and image coordinate systems are harmonized across all the sites. To harmonize DTI metrics, values are estimated for each voxel in an image to generate a histogram representing the whole image. Then, the Quantitative Imaging Toolkit (QIT) modules are utilized to scale the mode to a value of one and depict the subsequent harmonized histogram. The standardization of file formats, naming conventions, coordinate systems, and DTI metrics are qualitatively assessed. The histograms of the DTI metrics were generated for all the individual rodents per site. For inter-site analysis, an average of the individual scans was calculated to create a histogram that represents each site. In order to ensure the analysis can be run at the level of individual animals, the sham and TBI cohort were analyzed separately, which depicted the same harmonization factor. The results demonstrate that these processes qualitatively standardize the file formats, naming conventions, coordinate systems, and DTI metrics of the data. This assists in the ability to share data across the study, as well as disseminate tools that can help other researchers to strengthen the statistical power of their studies and analyze data more cohesively.

OBJECTIVE: Symptom counts as the basis for Post-Traumatic Stress Disorder (PTSD) diagnoses in the DSM presume each symptom is equally reflective of underlying disorder severity. However, the equal weight assumption fails to fit PTSD symptom data when tested. The present study developed an enhanced PTSD diagnosis based on (a) a conventional PTSD diagnosis from a clinical interview and (b) an empirical classification of full PTSD that reflected the relative clinical weights of each symptom. METHOD: Baseline structured interview data from Project Harmony (N = 2658) was used. An enhanced diagnosis for full PTSD was estimated using an empirical threshold from moderated nonlinear factor analysis (MNLFA) latent PTSD scale scores, in combination with a full conventional PTSD diagnosis based on interview data. RESULTS: One in 4 patients in the sample had a PTSD diagnosis that was inconsistent with their empirical PTSD grouping, such that the enhanced diagnostic standard reduced the diagnostic discrepancy rate by 20%. Veterans, and in particular female Veterans, were at greatest odds for discrepancy between their underlying PTSD severity and DSM diagnosis. CONCLUSION: Psychometric methodologies that differentially weight symptoms can complement DSM criteria and may serve as a platform for symptom prioritization for diagnoses in future editions of DSM.

Post-traumatic stress disorder (PTSD) is a debilitating condition that occurs following exposure to traumatic events. Current treatments, such as psychological debriefing and pharmacotherapy, often have limited efficacy and may result in unwanted side effects, making early intervention is a more desirable strategy. In this study, we investigated the efficacy of a single dose of pulsed (10 Hz) 810 nm laser-phototherapy (P-PT) as an early intervention for preventing PTSD-like comorbidities in rats induced by single inescapable electric foot shock following the single prolonged stress (SPS&S). As indicated by the results of the open filed test, elevated plus maze test, and contextual fear conditioning test, P-PT prevented the development of anxiety and freezing behaviors in rats exposed to the SPS&S. We also compared the effects of P-PT and continuous wave 810 nm laser-phototherapy (CW-PT) in preventing PTSD-like comorbidities in rats. The results revealed that P-PT was effective in preventing both freezing and anxiety behavior in stressed rats. In contrast, CW-PT only had a preventive effect on freezing behavior but not anxiety. Additionally, P-PT significantly reduced the c-fos expression in cingulate cortex area 1(Cg1) and infralimbic cortex (IL) of stressed rats, while CW-PT had no significant effects on c-fos expression. Taken together, our results demonstrate that P-PT is a highly effective strategy for preventing the occurrence of PTSD-like comorbidities in rats.
