Exposure to war traumatic experiences, post-traumatic stress disorder and post-traumatic growth among nurses in Gaza.

What is known on the subject? This study builds on existing research on war-related factors that may affect health-care staff by particularly focusing on trauma exposure in both professional and everyday life, as well as on correlates of later positive psychological changes. What this paper adds to existing knowledge? It shows that one in five nursing staff working in Gaza experienced post-traumatic stress symptoms within the clinical range, 2 years after an incursion on Gaza and after being exposed to substantial trauma during this period. Participants appeared to develop a variety of post-traumatic growth responses following trauma exposure. Although nurses experienced traumatic events both as civilians and in their health-care capacity, personal exposure was strongly associated with PTSD symptoms. What are the implications for practice? Support to nursing and other health-care professionals in war situations should entail different levels, remain available well after an acute conflict, and take into consideration both personal and practice-related traumatic events. Mental health nursing practitioners can play a pivotal role in this. To establish the association between war traumatic experiences, post-traumatic stress disorder (PTSD) symptoms and post-traumatic growth among nurses in the Gaza Strip, 2 years after an incursion on Gaza, and during a period of ongoing trauma exposure. This study builds on existing evidence by considering exposure to personal and work-related traumatic events, and on factors associated with later positive psychological adaptation. The sample consisted of 274 randomly selected nurses in Gaza who completed the Gaza Traumatic Events Checklist, PTSD Checklist, and Posttraumatic Growth Inventory. Of the nurses, 19.7% reported full PTSD. There was a significant relationship between traumatic events and PTSD scores; as well as between community-related traumatic events and post-traumatic growth. Participants reported a range of traumatic events, but PTSD and post-traumatic growth scores were more strongly associated with community rather than work-related traumas. Nursing professionals experienced high levels of distress 2 years following an acute period of conflict, both as civilians and in their health-care capacity. There is need for different levels of support for health-care staff in war-affected areas. Mental health nursing professionals have a central role in training, counselling and support to other health-care colleagues.

Defining Subthreshold PTSD in the DSM-IV Literature: A Look Toward DSM-5.

Subthreshold posttraumatic stress disorder (PTSD), whether due to absence of symptom development or partial remission, is the subject of research and clinical work despite being absent from the DSM. A problem with the literature is that subthreshold definitions are inconsistent across studies and therefore aggregating results is difficult. This study compared the diagnostic hit rates and validity of commonly used definitions of Subthreshold PTSD in a single sample. Three definitions of Subthreshold PTSD were extracted from the literature and two were formed, including a model of DSM-5 PTSD-criterion sets, and a definition that requires six or more PTSD symptoms, but no particular criterion set. Participants (N = 654) with a criterion A stressor, but without full PTSD diagnosis, were included. Most individuals did not meet any definition of Subthreshold PTSD. Findings are discussed in light of previous research and need for increased understanding of the diagnostic implications of Subthreshold PTSD.

Examining PTSD treatment choice among individuals with subthreshold PTSD

Subthreshold posttraumatic stress disorder (PTSD) is associated with impairment and has a prevalence rate comparable to full PTSD. Yet, little is known regarding treatment preferences among individuals with subthreshold PTSD, even though they seek trauma-related treatment at a similar rate to those with full PTSD. This study explored subthreshold diagnostic PTSD diagnostic category and treatment preference in undergraduate (N = 439) and trauma-exposed community (N = 203) samples. Participants completed the Posttraumatic Stress Diagnostic Scale (PDS), viewed standardized treatment rationales, and made a hypothetical PTSD treatment choice: prolonged exposure (PE), sertraline, combination treatment, or no treatment. The PDS was used to categorize individuals into four PTSD categories: no trauma exposure, trauma exposure only, subthreshold PTSD, and full PTSD. Within the samples, 8.9% (n = 39) of undergraduates and 16.7% (n = 34) of community members met subthreshold PTSD criteria. The majority of individuals with subthreshold PTSD in each sample reported impairment, 59.0% of undergraduates and 76.5% of community members. Within subthreshold PTSD groups, the most commonly selected treatments were PE (61.5%) for undergraduates and combination treatment (47.1%) for community members. Findings underscore the necessity of further examining subthreshold PTSD, which may hold important clinical implications for treatment processes and outcomes.

Mitochondrial genetic variants identified to be associated with posttraumatic stress disorder.

Despite the fact that mitochondrial dysfunctions are increasingly recognized as key components in stress-related mental disorders, very little is known about the association between posttraumatic stress disorder (PTSD) and mitochondrial variants. To identify susceptibility mitochondrial genes for PTSD, we analyzed a total number of 978 mitochondrial single-nucleotide polymorphisms (mtSNPs) in a sample of 1238 individuals participating in the KORA (Cooperative Health Research in the Region of Augsburg) study. Participants were classified with ‘no PTSD', ‘partial PTSD' or ‘full PTSD' by applying the Posttraumatic Diagnostic Scale and the Impact of Event Scale. To assess PTSD–mtSNP association while taking heteroplasmy into account, we used the raw signal intensity values measured on the microarray and applied linear regression. Significant associations were obtained between full versus no PTSD and two mtSNPs; mt8414C→T (β=−0.954±0.06, Padjusted=0.037) located in adenosine triphosphate (ATP) synthase subunit 8 (MT-ATP8) and mt12501G→A (β=−1.782±0.40, Padjusted=0.015) located in the NADH dehydrogenase subunits 5 (MT-ND5). Heteroplasmy for the two variants towards a larger number of the respective minor alleles increases the risk of having PTSD. NADH dehydrogenase and ATP synthase are both linked to the regulation of reactive oxygen species. Our results highlight the important role of the mitochondrial genome among the factors that contribute to the risk of PTSD. Mitochondrial genetic variants may be more important than has previously been assumed, leading to further insights regarding effects of existing medications, or even to the development of innovative treatments. As this is the first mitochondrial genome-wide association study for PTSDs, further analyses are needed to follow up on the present findings.

Feasibility of a screening program for at-risk children following accidental injury.

Screening is recommended as a simple method for identifying those who should be monitored for risk following trauma. Effective methods for implementing large-scale screening programs are yet to be established. This study tested the feasibility and utility of a screening program with hospitalized youth exposed to injury in 3 Australian hospitals. Eligible families (N = 1,134) were contacted and 546 children (48.0%) screened for risk of posttraumatic stress disorder (PTSD) at 1-2 weeks postinjury. There were 95 (17.4%) children whose screen result was at risk. A rescreening phase was introduced during the study, with 68 children completing the rescreen at 4-6 weeks postinjury, and 26 (38.2% of those rescreened) still at risk. Of those initially screened, 29 (5.3%) completed diagnostic assessments, 21 (3.8%) were diagnosed with partial or full PTSD, and 17 (3.1%) commenced treatment. Screening was successful at identifying and reaching children with PTSD, but the response rate was lower than expected, which limited the utility of the program. The addition of a rescreening phase demonstrated that not all at-risk children required intervention. These findings replicate previous studies that have shown natural remission in PTSD symptoms and highlight the potential for rescreening as part of a watchful waiting approach.

PTSD symptom severity is associated with increased recruitment of top-down attentional control in a trauma-exposed sample.

BackgroundRecent neuroimaging work suggests that increased amygdala responses to emotional stimuli and dysfunction within regions mediating top down attentional control (dorsomedial frontal, lateral frontal and parietal cortices) may be associated with the emergence of anxiety disorders, including posttraumatic stress disorder (PTSD). This report examines amygdala responsiveness to emotional stimuli and the recruitment of top down attention systems as a function of task demands in a population of U.S. military service members who had recently returned from combat deployment in Afghanistan/Iraq. Given current interest in dimensional aspects of pathophysiology, it is worthwhile examining patients who, while not meeting full PTSD criteria, show clinically significant functional impairment.MethodsFifty-seven participants with sub-threshold levels of PTSD symptoms completed the affective Stroop task while undergoing fMRI. Participants with PTSD or depression at baseline were excluded.ResultsGreater PTSD symptom severity scores were associated with increased amygdala activation to emotional, particularly positive, stimuli relative to neutral stimuli. Furthermore, greater PTSD symptom severity was associated with increased superior/middle frontal cortex response during task conditions relative to passive viewing conditions. In addition, greater PTSD symptom severity scores were associated with: (i) increased activation in the dorsolateral prefrontal, lateral frontal, inferior parietal cortices and dorsomedial frontal cortex/dorsal anterior cingulate cortex (dmFC/dACC) in response to emotional relative to neutral stimuli; and (ii) increased functional connectivity during emotional trials, particularly positive trials, relative to neutral trials between the right amygdala and dmFC/dACC, left caudate/anterior insula cortex, right lentiform nucleus/caudate, bilateral inferior parietal cortex and left middle temporal cortex.ConclusionsWe suggest that these data may reflect two phenomena associated with increased PTSD symptomatology in combat-exposed, but PTSD negative, armed services members. First, these data indicate increased emotional responsiveness by: (i) the positive relationship between PTSD symptom severity and amygdala responsiveness to emotional relative to neutral stimuli; (ii) greater BOLD response as a function of PTSD symptom severity in regions implicated in emotion (striatum) and representation (occipital and temporal cortices) during emotional relative to neutral conditions; and (iii) increased connectivity between the amygdala and regions implicated in emotion (insula/caudate) and representation (middle temporal cortex) as a function of PTSD symptom severity during emotional relative to neutral trials. Second, these data indicate a greater need for the recruitment of regions implicated in top down attention as indicated by (i) greater BOLD response in superior/middle frontal gyrus as a function of PTSD symptom severity in task relative to view conditions; (ii) greater BOLD response in dmFC/dACC, lateral frontal and inferior parietal cortices as a function of PTSD symptom severity in emotional relative to neutral conditions and (iii) greater functional connectivity between the amygdala and inferior parietal cortex as a function of PTSD symptom severity during emotional relative to neutral conditions.

Prevalence of traumatic events and PTSD symptoms among secondary school students in Baghdad

BackgroundPeople in Iraq have been more or less continually exposed to war for more than three decades. Studies with Iraqi participants report high prevalence rates of posttraumatic stress disorder (PTSD) and related problems.MethodsThe aim of this study is to measure the prevalence of traumatic events and to screen the prevalence of PTSD symptoms among Iraqi secondary school students. Four self-report scales were administered to 403 secondary school students, aged 16–19 (61% male and 31% female). These scales were Baghdad Trauma History Screen, the Scale of Posttraumatic Stress Symptoms (SPTSS), Social Support Scale, and Scale of Religious Coping.ResultsThe results showed that 84% of participants experienced at least one traumatic event. Of these, 61% fully met the criteria for PTSD; 65% of the females and 58% of the males. PTSD symptoms were correlated with 20 positive religious coping but not with social support.ConclusionsIt’s clear that traumatic events were speared widely among the participants and the result showed that the vast majority of participants were exposed to different types of traumatic events. In addition, many of the participants have met full PTSD criteria and others had partial PTSD.

Psychophysiological response to virtual reality and subthreshold posttraumatic stress disorder symptoms in recently deployed military.

Subthreshold posttraumatic stress disorder (PTSD) has garnered recent attention because of the significant distress and functional impairment associated with the symptoms as well as the increased risk of progression to full PTSD. However, the clinical presentation of subthreshold PTSD can vary widely and therefore is not clearly defined, nor is there an evidence-based treatment approach. Thus, we aim to further the understanding of subthreshold PTSD symptoms by reporting the use of a virtual combat environment in eliciting distinctive psychophysiological responses associated with PTSD symptoms in a sample of subthreshold recently deployed US service members. Heart rate, skin conductance, electromyography (startle), respiratory rate, and blood pressure were monitored during three unique combat-related virtual reality scenarios as a novel procedure to assess subthreshold symptoms in a sample of 78 service members. The Clinician-Administered PTSD Scale was administered, and linear regression analyses were used to investigate the relationship between symptom clusters and physiological variables. Among the range of psychophysiological measures that were studied, regression analysis revealed heart rate as most strongly associated with Clinician-Administered PTSD Scale-based measures hyperarousal (R = 0.11, p = .035,) reexperiencing (R = 0.24, p = .001), and global PTSD symptoms (R = 0.17, p = .003). Our findings support the use of a virtual reality environment in eliciting physiological responses associated with subthreshold PTSD symptoms.

Genomic predictors of combat stress vulnerability and resilience in U.S. Marines: A genome-wide association study across multiple ancestries implicates PRTFDC1 as a potential PTSD gene

Research on the etiology of post-traumatic stress disorder (PTSD) has rapidly matured, moving from candidate gene studies to interrogation of the entire human genome in genome-wide association studies (GWAS). Here we present the results of a GWAS performed on samples from combat-exposed U.S. Marines and Sailors from the Marine Resiliency Study (MRS) scheduled for deployment to Iraq and/or Afghanistan. The MRS is a large, prospective study with longitudinal follow-up designed to identify risk and resiliency factors for combat-induced stress-related symptoms. Previously implicated PTSD risk loci from the literature and polygenic risk scores across psychiatric disorders were also evaluated in the MRS cohort. Participants (N=3494) were assessed using the Clinician-Administered PTSD Scale and diagnosed using the DSM-IV diagnostic criterion. Subjects with partial and/or full PTSD diagnosis were called cases, all other subjects were designated controls, and study-wide maximum CAPS scores were used for longitudinal assessments. Genomic DNA was genotyped on the Illumina HumanOmniExpressExome array. Individual genetic ancestry was determined by supervised cluster analysis for subjects of European, African, Hispanic/Native American, and other descent. To test for association of SNPs with PTSD, logistic regressions were performed within each ancestry group and results were combined in meta-analyses. Measures of childhood and adult trauma were included to test for gene-by-environment (GxE) interactions. Polygenic risk scores from the Psychiatric Genomic Consortium were used for major depressive disorder (MDD), bipolar disorder (BPD), and schizophrenia (SCZ). The array produced >800K directly genotyped and >21M imputed markers in 3494 unrelated, trauma-exposed males, of which 940 were diagnosed with partial or full PTSD. The GWAS meta-analysis identified the phosphoribosyl transferase domain containing 1 gene (PRTFDC1) as a genome-wide significant PTSD locus (rs6482463; OR=1.47, SE=0.06, p=2.04×10(-9)), with a similar effect across ancestry groups. Association of PRTFDC1 with PTSD in an independent military cohort showed some evidence for replication. Loci with suggestive evidence of association (n=25 genes, p<5×10(-6)) further implicated genes related to immune response and the ubiquitin system, but these findings remain to be replicated in larger GWASs. A replication analysis of 25 putative PTSD genes from the literature found nominally significant SNPs for the majority of these genes, but associations did not remain significant after correction for multiple comparison. A cross-disorder analysis of polygenic risk scores from GWASs of BPD, MDD, and SCZ found that PTSD diagnosis was associated with risk sores of BPD, but not with MDD or SCZ. This first multi-ethnic/racial GWAS of PTSD highlights the potential to increase power through meta-analyses across ancestry groups. We found evidence for PRTFDC1 as a potential novel PTSD gene, a finding that awaits further replication. Our findings indicate that the genetic architecture of PTSD may be determined by many SNPs with small effects, and overlap with other neuropsychiatric disorders, consistent with current findings from large GWAS of other psychiatric disorders.

Post-Traumatic Stress Symptoms in Pediatric Heart Transplant Recipients.

Traumatic experiences are not unusual in pediatric heart transplant (HT) recipients before and after transplantation. Post-traumatic stress symptoms (PTSS) present at the time of transplant evaluation and developing afterward occur with an unknown frequency. We sought to determine the burden of these symptoms in heart transplant patients. We reviewed 51 consecutive HTs between 2003-2007, including 40 primary transplants and 11 re-transplants. Symptoms were present in 17 of the 51 patients (34%) at the time of orthotopic heart transplantation evaluation. None met the criteria for full post traumatic stress disorder. Transplant complications were examined. Nineteen subjects of the total sample had rejection in the first year following transplant. Rejection rates in the first year was 41% for those with PTSS (7 of 17 patients) and 36% for those without (12 of 33 patients) (P=n.s). Of those patients presenting for a second heart transplant, 55% had PTSS at the time of transplant evaluation and/or the peritransplant period; whereas, (28%) undergoing a primary transplant had PTSS. In addition to symptoms resulting from the disease process leading to HT and other prior experiences, the HT itself seems to present a large psychiatric burden on patients. All patients need to be followed before and after HT for signs and symptoms related to PTSS. Future studies should be undertaken to determine if preventative detection and treatment of patients with these PTSS symptoms early can lead to better outcomes.

The 6-month prevalence of posttraumatic stress syndrome (PTSS) among older adults: validity and reliability of the PTSS scale.

To document the 6-month prevalence of posttraumatic stress syndrome (PTSS) in the older adult population and the validity of a PTSS Scale in an epidemiologic setting. Data came from the Enquête sur la santé des aînés et l'utilisation des services de santé (ESA Services Study) conducted during 2012-2013 using a probability sample of older adults seeking medical services in primary health clinics. Results showed that a first-order PTSS measurement model consisting of 3 indicators-the number of lifetime traumatic events, the frequency of reactions and symptoms of distress associated with the traumatic events, and the presence of consequences on the social functioning-was plausible. Reliability of the PTSS was 0.82. According to the PTSS, 11.1% of the older adult patients presented with PTSS, but only 21.7% of them reported an impact of their symptoms on their social functioning. The prevalence of older adults meeting the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria for full posttraumatic stress disorder (PTSD) reached 1.8%, and 1.8% of older adults reached criteria for partial PTSD. Our results also showed that women were more at risk to report PTSS than men and that older adults aged 75 years and older were less likely to report these symptoms than those aged between 65 and 74 years. PTSS is a common mental health problem among adults aged 65 and older and seeking health services in the general medical sector.

Diagnostic Utility of the Posttraumatic Stress Disorder (PTSD) Checklist for Identifying Full and Partial PTSD in Active-Duty Military.

The aim of this study was to determine optimally efficient cutoff scores on the Posttraumatic Stress Disorder Checklist (PCL) for identifying full posttraumatic stress disorder (PTSD) and partial PTSD (P-PTSD) in active-duty Marines and Sailors. Participants were 1,016 Marines and Sailors who were administered the PCL and Clinician-Administered PTSD Scale (CAPS) 3 months after returning from Operations Iraqi and Enduring Freedom. PCL cutoffs were tested against three CAPS-based classifications: full PTSD, stringent P-PTSD, and lenient P-PTSD. A PCL score of 39 was found to be optimally efficient for identifying full PTSD. Scores of 38 and 33 were found to be optimally efficient for identifying stringent and lenient P-PTSD, respectively. Findings suggest that the PCL cutoff that is optimally efficient for detecting PTSD in active-duty Marines and Sailors is substantially lower than the score of 50 commonly used by researchers. In addition, findings provide scores useful for identifying P-PTSD in returning service members.

Examining Mechanisms of Change in a Yoga Intervention for Women: The Influence of Mindfulness, Psychological Flexibility, and Emotion Regulation on PTSD Symptoms

This study explored possible mechanisms through which symptoms of posttraumatic stress disorder (PTSD) were reduced in a randomized controlled trial comparing the effect of a yoga intervention with an assessment control. We examined whether changes in psychological flexibility, mindfulness, and emotion regulation strategies (expressive suppression and reappraisal) were associated with posttreatment PTSD symptoms for 38 women with Diagnostic and Statistical Manual of Mental Disorders Fourth Edition full or subthreshold PTSD. Hierarchical linear regression models revealed that expressive suppression significantly decreased for the yoga group relative to the assessment control. Psychological flexibility increased significantly for the control but not yoga group. However, increases in psychological flexibility were associated with decreases in PTSD symptoms for the yoga but not control group. Preliminary findings suggest that yoga may reduce expressive suppression and may improve PTSD symptoms by increasing psychological flexibility. More research is needed to replicate and extend these findings.

Family violence exposure and associated risk factors for child PTSD in a Mexican sample

This study was undertaken in an effort to help illuminate the deleterious effects of traumatic stress on children and families in Mexico. Rates of exposure to traumatic events, family and community violence, and posttraumatic stress disorder (PTSD) were investigated in 87 school-age children and their mothers. Binary logistic regression analysis was performed to examine potential family and ecological risk factors for the presence of child PTSD. A total of 51 children (58.6%) reported an event that met the DSM-IV A criteria, and 36 children (41.4%; 20 boys and 16 girls) met criteria for full PTSD. Traumatic exposure in this sample was considerable, particularly intense, and chronic as a result of interpersonal violence in the home and community. Results support the need for preventive systemic interventions targeting the individual level, parent–child dyadic level, and the larger cultural and community context.

The psychiatric sequelae of burn injury

ObjectiveTo examine factors predicting psychiatric morbidity, taking into account the full range of psychiatric disorders before and after burn injury. MethodsA cohort of 107 patients consecutively admitted to a Swedish national burn center was examined for lifetime psychiatric morbidity, as well as 94 patients at 1 year postinjury. Sixty-seven individuals, some from that same cohort, were interviewed at 2 to 7years postinjury. The predictive effects of psychiatric history, personality and other risk factors for psychiatric morbidity following burn were evaluated with multiple regression analyses. ResultsThe prevalence of having a psychiatric disorder preburn was 57%. One year postinjury 19% had minor or major depression and 23% had subsyndromal or full posttraumatic stress disorder. At 2 to 7years, 31% fulfilled the criteria for a psychiatric disorder. The strongest contributing factors were a history of psychiatric morbidity and neuroticism. ConclusionsTwo-thirds of the patients had a lifetime psychiatric disorder, and one-third had a psychiatric diagnosis 2 to 7years postburn. Mental health problems can have a major impact on daily life and functional abilities. Thus, identification and treatment of a range of psychiatric disorders, taking into account preburn psychiatric disorders and personality, is important for optimal adjustment after burn.

Subthreshold Posttraumatic Stress Disorder in the World Health Organization World Mental Health Surveys

BackgroundAlthough only a few people exposed to a traumatic event (TE) develop posttraumatic stress disorder (PTSD), symptoms that do not meet full PTSD criteria are common and often clinically significant. Individuals with these symptoms sometimes have been characterized as having subthreshold PTSD, but no consensus exists on the optimal definition of this term. Data from a large cross-national epidemiologic survey are used in this study to provide a principled basis for such a definition. MethodsThe World Health Organization World Mental Health Surveys administered fully structured psychiatric diagnostic interviews to community samples in 13 countries containing assessments of PTSD associated with randomly selected TEs. Focusing on the 23,936 respondents reporting lifetime TE exposure, associations of approximated DSM-5 PTSD symptom profiles with six outcomes (distress-impairment, suicidality, comorbid fear-distress disorders, PTSD symptom duration) were examined to investigate implications of different subthreshold definitions. ResultsAlthough consistently highest outcomes for distress-impairment, suicidality, comorbidity, and PTSD symptom duration were observed among the 3.0% of respondents with DSM-5 PTSD rather than other symptom profiles, the additional 3.6% of respondents meeting two or three of DSM-5 criteria B–E also had significantly elevated scores for most outcomes. The proportion of cases with threshold versus subthreshold PTSD varied depending on TE type, with threshold PTSD more common following interpersonal violence and subthreshold PTSD more common following events happening to loved ones. ConclusionsSubthreshold DSM-5 PTSD is most usefully defined as meeting two or three of DSM-5 criteria B–E. Use of a consistent definition is critical to advance understanding of the prevalence, predictors, and clinical significance of subthreshold PTSD.

A Pilot Study of a Randomized Controlled Trial of Yoga as an Intervention for PTSD Symptoms in Women

Posttraumatic stress disorder (PTSD) is a debilitating condition that affects approximately 10% of women in the United States. Although effective psychotherapeutic treatments for PTSD exist, clients with PTSD report additional benefits of complementary and alternative approaches such as yoga. In particular, yoga may downregulate the stress response and positively impact PTSD and comorbid depression and anxiety symptoms. We conducted a pilot study of a randomized controlled trial comparing a 12-session Kripalu-based yoga intervention with an assessment control group. Participants included 38 women with current full or subthreshold PTSD symptoms. During the intervention, yoga participants showed decreases in reexperiencing and hyperarousal symptoms. The assessment control group, however, showed decreases in reexperiencing and anxiety symptoms as well, which may be a result of the positive effect of self-monitoring on PTSD and associated symptoms. Between-groups effect sizes were small to moderate (0.08-0.31). Although more research is needed, yoga may be an effective adjunctive treatment for PTSD. Participants responded positively to the intervention, suggesting that it was tolerable for this sample. Findings underscore the need for future research investigating mechanisms by which yoga may impact mental health symptoms, gender comparisons, and the long-term effects of yoga practice.

Functional Status after Blast-Plus-Impact Complex Concussive Traumatic Brain Injury in Evacuated United States Military Personnel

Fundamental questions remain unanswered about the longitudinal impact of blast-plus-impact complex traumatic brain injuries (TBI) from wars in Iraq and Afghanistan. This prospective, observational study investigated measures of clinical outcome in US military personnel evacuated to Landstuhl Regional Medical Center (LRMC) in Germany after such "blast-plus" concussive TBIs. Glasgow Outcome Scale-Extended assessments completed 6-12 months after injury indicated a moderate overall disability in 41/47 (87%) blast-plus TBI subjects and a substantial but smaller number (11/18, 61%, p=0.018) of demographically similar US military controls without TBI evacuated for other medical reasons. Cognitive function assessed with a neuropsychological test battery was not different between blast-plus TBI subjects and controls; performance of both groups was generally in the normal range. No subject was found to have focal neurological deficits. However, 29/47 (57%) of blast-plus subjects with TBI met all criteria for post-traumatic stress disorder (PTSD) versus 5/18 (28%) of controls (p=0.014). PTSD was highly associated with overall disability; 31/34 patients with PTSD versus 19/31 patients who did not meet full PTSD criteria had moderate to severe disability (p=0.0003). Symptoms of depression were also more severe in the TBI group (p=0.05), and highly correlated with PTSD severity (r=0.86, p<0.0001). Thus, in summary, high rates of PTSD and depression but not cognitive impairment or focal neurological deficits were observed 6-12 months after concussive blast-plus-impact complex TBI. Overall disability was substantially greater than typically reported in civilian non-blast concussive ("mild") patients with TBI, even with polytrauma. The relationship between these clinical outcomes and specific blast-related aspects of brain injuries versus other combat-related factors remains unknown.

Trastorno de estrés postraumático en escolares tras el terremoto de Lorca (España) en 2011

ObjectiveTo determine the prevalence of post-traumatic stress disorder (PTSD) in children after the 2011 earthquake in Lorca (Spain). MethodsBy using a cross-sequential design, children aged from 8 to 12 years (495 students at 1 month and 374 at 1 year) were assessed for full and partial PTSD using the Post-traumatic Children's Symptoms Stress Disorder Scale. ResultsThe percentage of children with PTSD was 55.4% (65.6% of girls and 46.9% of boys) at 1 month and 40.1% (44.5% girls and 35.9% children) at 1 year. One in two young girls (8-10 years) had PTSD 1 year after the earthquake. DiscussionA differential effect was observed due to gender and age, in which younger children, especially girls, were particularly at risk, even 1 year after the earthquake.

Comparing Response to Cognitive Processing Therapy in Military Veterans With Subthreshold and Threshold Posttraumatic Stress Disorder

Research suggests that subthreshold posttraumatic stress disorder (PTSD) symptomatology is associated with increased risk for psychological and functional impairment, including increased risk for suicidal ideation. However, it does not appear that any studies to date have investigated whether subthreshold PTSD can effectively be treated with evidence-based, trauma-focused treatment. Accordingly, we tested response to cognitive processing therapy (CPT) in 2 groups of military veterans receiving care at a VA outpatient specialty clinic, 1 with subthreshold PTSD at pretreatment (n = 51) and the other with full, diagnostic PTSD (n = 483). Multilevel analysis revealed that both groups experienced a significant decrease in PTSD symptoms over the course of therapy (the full and subthreshold PTSD groups experienced an average decrease of 1.79 and 1.52 points, respectively, on the PTSD Checklist with each increment of time, which was coded from 0 at pretreatment to 13 at posttreatment). After controlling for pretreatment symptom severity, a between-groups difference was not found. These results suggest that CPT is an effective form of treatment among military veterans, and that its effectiveness does not differ between subthreshold and threshold groups.
