A late-life neurogenetic signature of exposure to combat stress - A monozygotic discordant twin study

Animal models suggest that experiencing high-stress levels induces changes in amygdalar circuitry and gene expression. In humans, combat exposure has been shown to alter amygdalar responsivity and connectivity, but abnormalities have been indicated to normalize at least partially upon the termination of stress exposure. In contrast, other evidence suggests that combat exposure continues to exert influence on exposed individuals well beyond deployment and homecoming, as indicated by longitudinal psychosocial evidence from veterans, and observation of greater health decline in veterans late in life. Accordingly, the experience of combat stress early in life may affect amygdalar responsivity late in life, a possibility requiring careful consideration of the confounding effects of aging, genetic factors, and symptoms of post-traumatic stress disorder. Here, we investigated amygdalar responsivity in a unique sample of 16 male monozygotic (MZ) twin pairs in their sixties, where one but not the other sibling had been exposed to combat stress in early adulthood. Forty years after combat experience, a generally blunted amygdalar response was observed in combat-exposed veterans compared to their non-exposed twin siblings. Spatial associations between these phenotypical changes and patterns of gene expression in the brain were found for genes involved in the synaptic organization and chromatin structure. Protein-protein interactions among the set of identified genes pointed to histone modification mechanisms. We conclude that exposure to combat stress early in life continues to impact brain function beyond the termination of acute stress and appears to exert prolonged effects on amygdalar function later in life via neurogenetic mechanisms.

Symonds on fear and Post Traumatic Stress Disorder (PTSD)

Prominent English neurologist Sir Charles Symonds, during World War II service with the Royal Air Force, published a series of articles emphasizing the role of fear initiating psychological breakdown in combat airmen (termed Lack of Moral Fibre). Having served in a medical capacity in the previous war, Symonds re-presented the phylogenetic conceptualizations formed by his colleagues addressing 'shell shock'. In 2013, the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) re-classified Post Traumatic Stress Disorder (PTSD), removing the diagnosis from the category of Anxiety Disorders. This was the view introduced a century ago by the trench doctors of World War I and affirmed by Symonds' clinical experience and studies in World War II.

"Brothers in Arms": Secondary Traumatization and Sibling Relationship Quality Among Siblings of Combat Veterans

The aversive impact of exposure to combat and posttraumatic stress disorder (PTSD) on family members has been examined mainly among veterans' partners and offspring. No study has examined secondary traumatization in veterans' siblings and the role of relationship quality in these links. The present study aimed to assess secondary PTSD symptoms (PTSS) and general distress among siblings of combat veterans, and the role of sibling relationship quality in the association between veterans' exposure to combat and PTSS and sibling secondary PTSS. A sample of 106 adult dyads of Israeli combat veterans and their closest in age siblings responded to self-report questionnaires in a cross-sectional study design. The rates of sibling secondary PTSS and general distress were relatively low. However, veterans' exposure to combat and PTSS were positively related to siblings' secondary PTSS. Importantly, veterans' PTSS mediated the association between veterans' exposure to combat and siblings' secondary PTSS, only among sibling dyads with high levels of warmth and low levels of conflict in their relationship. Furthermore, the inclusion of siblings general distress contributed to heightened sibling secondary PTSS, but only the warmth dimension moderated the link between veterans' PTSS and siblings' secondary PTSS. Findings suggest that veterans' PTSS is implicated in their siblings' secondary PTSS. Veterans' PTSS might also serve as a possible mechanism for the links between exposure to combat and siblings' secondary PTSS. Moreover, relationship quality with a sibling veteran might take a toll in the form of siblings' secondary PTSS following veteran military service.

Distinguishing the Effects of Life Threat, Killing Enemy Combatants, and Unjust War Events in U.S. Service Members

Although previous studies have identified behavioral health risks associated with combat exposure, it is unclear which types of combat events are associated with these risks, particularly regarding contrasts among the risks associated with life-threatening experiences, killing combatants, and exposure to unjust war events, such as killing a noncombatant or being unable to help civilian women and children. In the present study, we examined surveys from 402 soldiers following deployment (i.e., baseline) and again 13 months later (i.e., Year 1). Regression analyses were conducted across a range of behavioral health (e.g., posttraumatic stress disorder, depression, suicide ideation, anxiety, somatic, insomnia, aggression) and benefit-finding measures, each controlling for two combat event categories while assessing the predictive utility of a third. The results suggested that life-threatening events were associated with poor behavioral health at baseline, relative risk (RR) = 10.00, but not at Year 1, RR = 2.67. At both baseline and Year 1, killing enemy combatants was not associated with behavioral health, RRs = 1.67-3.33, but was positively associated with benefit-finding, RRs = 26.67-40.00. Exposure to unjust war events was associated with a transdiagnostic pattern of behavioral health symptoms at baseline, RR = 40.00, and Year 1, RR = 23.33. Overall, the results suggest unjust war event exposure is particularly injurious, above and beyond exposure to other combat-related events. Future research can build on these findings to develop clearer descriptions of the combat events that might place service members at risk for moral injury and inform the development of assessment and treatment options.

Women in combat: The effects of combat exposure and gender on the incidence and persistence of posttraumatic stress disorder diagnosis

Recent expansions in the roles of women in combat have prompted increased interest in the psychological toll combat exposure may have on female service members as compared to males. This study examined the interactive effects of gender and combat exposure on transitions in posttraumatic stress disorder (PTSD) diagnostic status (presence or absence of PTSD diagnosis). We used administrative data of 20,000 U.S. Army soldiers whose combat exposure was assessed after return from deployment between January 1, 2008 and June 30, 2014; soldiers' PTSD diagnostic status was determined using International Classification of Diseases-9 diagnoses at four time points separated by 12 months. We used a mixed-effects logit transition model to examine the effects of combat and gender on incidence, persistence, and prevalence of PTSD diagnosis. Incidence and prevalence of PTSD diagnosis were higher among women, but persistence of PTSD diagnosis was higher in men. Higher rates of new PTSD diagnosis among women were not dependent on combat exposure, suggesting that other types of trauma may be responsible for increased rates among women. Gender differences in prevalence and persistence of PTSD diagnosis were greater among combat-exposed soldiers than among those not exposed to combat. Men maintained a PTSD diagnosis over longer periods of time than women suggesting greater PTSD persistence, and this pattern was particularly pronounced among soldiers exposed to combat. These results have implications for the recent policy changes and gender-based prevention strategies, and suggest that women in combat roles may be no more vulnerable to PTSD than are their male counterparts. Though the gender differences were small, they are indicative of healthcare utilization patterns that may be important for prevention and that warrant further exploration.

"Medicinable Literature": Bibliotherapy, Literary Caregiving, and the First World War

Histories of bibliotherapy often emphasize the importance of the First World War in stimulating the development of bibliotherapeutic theory and practice. The word itself was used in a 1916 article by the American author Samuel McChord Crothers, while histories of bibliotherapy in the United Kingdom often foreground H. F. Brett-Smith's so-called "fever chart" of therapeutic books for treating shell-shocked soldiers. Despite this, however, we argue that a full account of wartime bibliotherapy (particularly the importance of British hospital libraries in its development) has yet to be told. This article draws on the papers of British military hospital personnel to describe the range of "literary caregiving" supporting the treatment of sick and wounded soldiers during the conflict. It traces the social and professional networks underlying these schemes. Finally, it shows how British volunteer librarians helped develop a specifically medicalized language of caregiving through books, thereby contributing to the early development of bibliotherapy.

Impostorism, subjective age, and perceived health among aging veterans

RATIONALE

Aging veterans often suffer from increased vulnerability, manifested among other things in old subjective age and poor perceived health. Though research has documented the contribution of trauma related variables to these negative appraisals, their associations with impostorism (i.e., the subjective experience that one is less adequate than others perceive) remain unexamined.

OBJECTIVE

Filling this gap, this study explored the relations between impostorism and subjective age and perceived health among aging combat veterans.

METHOD

The study was conducted among 146 Israeli veterans of the 1973 Yom Kippur War. Participants were assessed for combat exposure, Posttraumatic Stress Disorder (PTSD) symptoms, and health-related behaviors during middle adulthood (1991; T1), and for subjective age, perceived health, impostorism, PTSD symptoms, and depressive symptoms during old age (2018; T2).

RESULTS

The veterans' impostorism was associated with relatively old subjective age and poor perceived health, above and beyond the effects of age, health-related behaviors, combat exposure, depressive symptoms, and PTSD symptoms.

CONCLUSIONS

The current results suggest that impostorism may contribute to veterans' stress and negatively affect their evaluations regarding age and health.

Behavioral health of US military veterinary personnel deployed to Afghanistan

OBJECTIVE To compare symptoms of compromised behavioral health (BH symptoms) and factors protecting against those symptoms (protective factors) in military veterinary and nonveterinary health-care personnel deployed to Afghanistan. DESIGN Cross-sectional survey. SAMPLE 237 deployed military health-care personnel (21 veterinary and 216 nonveterinary). PROCEDURES Surveys were administered to participants during combat deployment in Afghanistan in 2013 to collect information on BH symptoms and protective factors. Data were compared between veterinary and nonveterinary health-care personnel by use of regression models controlling for demographic characteristics and deployment experiences. Partial correlations were computed to assess relationships between protective factors and BH symptoms, controlling for personnel type. RESULTS Less than 15% of veterinary and nonveterinary health-care personnel were at risk for suicidal ideation, major depressive disorder, generalized anxiety disorder, and posttraumatic stress disorder. After adjusting for covariates, both personnel types had similar levels of depression, posttraumatic stress disorder, and anxiety symptoms; however, veterinary personnel reported more distressing secondary traumatic stress symptoms and a greater number of anger reactions. Self-care, team support, and perceived supportive leadership were inversely associated with BH symptoms regardless of personnel type. Veterinary personnel engaged in less self-care, provided less team care, and rated leadership behaviors less positively than nonveterinary health-care personnel. CONCLUSIONS AND CLINICAL RELEVANCE Compared with nonveterinary health-care personnel, deployed veterinary personnel were at greater risk of generalized anxiety disorder and reported more secondary traumatic stress and anger reactions, but were less likely to be engaged in and exposed to protective factors. Interventions designed to promote self-care and team support for veterinary personnel and their leaders may reduce the occupational risk of BH symptoms in deployment and perhaps other settings.

Deconditioning and Time-Therapy

In view of the recent revival of interest in deconditioning, the treatment of a series of 35 cases of anxiety by this method may be of interest. This series has not been recorded previously although the treatment was carried out 20 years ago.

Canadian Military Nurse Deaths in the First World War

This paper examines the lives of sixty-one Canadian Nursing Sisters who served during the First World War, and whose deaths were attributed, more or less equally, to three categories: general illness, Spanish Influenza, and killed in action. The response by Canadian Army Medical Corps (CAMC) physicians to the loss of these early female officers who were, in fact, Canada's first female war casualties, suggests a gendered construction of illness at work in the CAMC. While nurses tried to prove themselves good soldiers, military physicians were quick to attribute their illnesses and deaths to horrific war conditions deemed unsuitable for women. This gendered response is particularly evident in how CAMC physicians invoked a causal role for neurasthenia or shell shock for the nurses' poor health. The health profile of these women also suggests that some of these deaths might have occurred had these women stayed in Canada, and it encourages future comparative research into death rates among physicians and orderlies.

Teaching dental students to interact with survivors of traumatic events: development of a two-day module

Dentists are likely to treat patients who have experienced a wide range of traumatic life events, including child abuse and neglect, domestic violence, sexual assault, elder abuse, and exposure to combat. In order to effectively treat survivors of traumatic events, dentists must understand how these patients may present in oral health settings, the basic mandated reporting requirements related to abuse and neglect, and communication strategies to help engage trauma survivors in dental treatment. A traditional lecture-format educational module on trauma-informed care was developed and implemented for second-year dental students (N=92) at one U.S. dental school, after which a needs assessment was performed (all 92 students participated). This assessment then informed development of an enhanced module for the subsequent group of second-year dental students (N=102) at the same school. The revised (final) module was more interactive in nature, expanded to multiple sessions, and included more discussion of mandated reporting and appropriate dentist-patient communication in relation to traumatic events. All 102 students participated in assessments of the revised module. Comparison of pre and post tests and needs assessments between the initial and final modules indicated that the extended, more interactive final module was more effective in meeting the educational objectives. Results showed that the final module increased the students' knowledge in the health-related manifestations of traumatic events and slightly improved their confidence levels in treating survivors of trauma. Dentists who are prepared to deliver trauma-informed care may help individual patients feel more at ease and increase engagement in regular preventive care. Suggestions for future educational efforts in this area are discussed.

Prospective evaluation of mental health and deployment experience among women in the US military

Previous research has shown that military women often experience potentially severe health outcomes following deployment. Data from the Millennium Cohort Study, a 21-year longitudinal study examining the health effects of military service, were used to examine this issue. In longitudinal analyses (2001-2008) carried out among US military women (n = 17,481), the authors examined positive screens for depression, anxiety, panic, and posttraumatic stress disorder in relation to deployment in support of the operations in Iraq and Afghanistan, while adjusting for relevant baseline and time-varying covariates. Women who were deployed and reported combat-related exposures had greater odds than nondeployed women of reporting symptoms of a mental health condition (odds ratio = 1.91, 95% confidence interval: 1.65, 2.20), after adjustment for demographic, military, and behavioral covariates. In addition, higher stress, problem drinking, and a history of mental illness were significantly associated with increased risk of later mental health conditions. In contrast, women in the Reserves or National Guard and those with higher education were at decreased risk of mental health conditions (all P 's < 0.01). As the roles and responsibilities of women in the military expand and deployments continue, designing better prevention and recovery strategies specifically for women are critical for overall force health protection and readiness.

Examining the role of combat loss among Vietnam War Veterans

Military combat often presents service members with a dual burden of coping with traumas of various types while also grappling with the deaths of close personal friends. At present, much less is known about the effects of bereavement in the context of war compared to other combat-related stressors. Studying a sample of combat veterans from the National Vietnam Veterans Readjustment Study (NVVRS), we examined the contribution of combat loss in psychological functioning and posttraumatic stress disorder (PTSD). When controlling for gender, age, ethnicity, educational background, exposure to nonbereavement combat stressors, and recent bereavement experiences, combat loss was uniquely associated with past and current functional impairments among the veterans, βs = .07 and .06, respectively, but was not related to the severity of PTSD. These findings highlight that combat loss might act as a uniquely challenging stressor among many service members and more empirical research is needed on this topic.

Cost effectiveness of virtual reality graded exposure therapy with physiological monitoring for the treatment of combat related post traumatic stress disorder

Virtual Reality Graded Exposure Therapy (VRGET) is an effective treatment for combat-related PTSD. We summarize the outcomes of a VRGET pilot study with 12 participants who completed one to multiple combat tours in support of the War on Terrorism and who were subsequently diagnosed with combat-related PTSD. Details of the collaborative program amongst the Virtual Reality Medical Center (VRMC), Office of Naval Research, the Naval Medical Center San Diego (NMCSD) and the Navy Hospital Camp Pendleton are discussed as is the VRGET outcomes of significant reductions in PTSD symptoms severity. We also described the estimated cost-effectiveness of VRGET for the treatment of combat-related PTSD, as contrasted to Treatment as Usual (TAU) for combat-related PTSD.

Alcohol use and alcohol-related problems before and after military combat deployment

CONTEXT

High rates of alcohol misuse after deployment have been reported among personnel returning from past conflicts, yet investigations of alcohol misuse after return from the current wars in Iraq and Afghanistan are lacking.

OBJECTIVES

To determine whether deployment with combat exposures was associated with new-onset or continued alcohol consumption, binge drinking, and alcohol-related problems.

DESIGN, SETTING, AND PARTICIPANTS

Data were from Millennium Cohort Study participants who completed both a baseline (July 2001 to June 2003; n=77,047) and follow-up (June 2004 to February 2006; n=55,021) questionnaire (follow-up response rate = 71.4%). After we applied exclusion criteria, our analyses included 48,481 participants (active duty, n = 26,613; Reserve or National Guard, n = 21,868). Of these, 5510 deployed with combat exposures, 5661 deployed without combat exposures, and 37 310 did not deploy.

MAIN OUTCOME MEASURES

New-onset and continued heavy weekly drinking, binge drinking, and alcohol-related problems at follow-up.

RESULTS

Baseline prevalence of heavy weekly drinking, binge drinking, and alcohol-related problems among Reserve or National Guard personnel who deployed with combat exposures was 9.0%, 53.6%, and 15.2%, respectively; follow-up prevalence was 12.5%, 53.0%, and 11.9%, respectively; and new-onset rates were 8.8%, 25.6%, and 7.1%, respectively. Among active-duty personnel, new-onset rates were 6.0%, 26.6%, and 4.8%, respectively. Reserve and National Guard personnel who deployed and reported combat exposures were significantly more likely to experience new-onset heavy weekly drinking (odds ratio [OR], 1.63; 95% confidence interval [CI], 1.36-1.96), binge drinking (OR, 1.46; 95% CI, 1.24-1.71), and alcohol-related problems (OR, 1.63; 95% CI, 1.33-2.01) compared with nondeployed personnel. The youngest members of the cohort were at highest risk for all alcohol-related outcomes.

CONCLUSION

Reserve and National Guard personnel and younger service members who deploy with reported combat exposures are at increased risk of new-onset heavy weekly drinking, binge drinking, and alcohol-related problems.

Configural cue performance in identical twins discordant for posttraumatic stress disorder: theoretical implications for the role of hippocampal function

BACKGROUND

A significant subgroup of individuals with posttraumatic stress disorder (PTSD) exhibits chronic, unremitting symptomatology that has also been associated with smaller hippocampal volume. The hippocampus plays a significant role in configural processing of contextual cues that facilitates context-appropriate extinction of conditioned fear. We test the hypothesis that hippocampus-based configural processing deficits are a pre-existing vulnerability factor for unremitting forms of PTSD.

METHODS

Participants included male monozygotic twin pairs who were discordant for combat trauma. In 18 twin pairs the combat-exposed brother developed unremitting PTSD, whereas in 23 pairs the combat-exposed brother never developed PTSD. Participants were compared in the capacity to solve allocentric spatial processing tasks, and this performance was examined for its relationship to the severity of PTSD symptomatology and hippocampal volume.

RESULTS

Although not completely differentiated from overall IQ, PTSD combat veterans demonstrated significantly impaired performance in configural processing relative to non-PTSD combat veterans. Despite having neither combat-exposure nor PTSD, the unexposed co-twins of combat veterans with PTSD displayed the same decrements as their brothers. Deficits were significantly related to PTSD severity and hippocampal volume.

CONCLUSIONS

The current study provides the first evidence that the relevance of the hippocampus in PTSD might be related to pre-existing configural cue processing deficits that predispose individuals to develop unremitting forms of the disorder.

Psychological Morbidity During The 2002 Deployment To Afghanistan

Questionnaires were completed by military personnel on arrival (n=1,696) in Kabul, Afghanistan and then again on departure (n=1,134). Analysis of the 113 personnel who completed both the arrivals and departures questionnaire revealed a lower alcohol use score after deployment (AUDIT mean difference (post-deployment - pre-deployment) = -0.39, 95% confidence interval (CI) = - 1.25 - +0.47) and no significant change to mental health (GHQ mean difference = 0.55, 95% CI = -0.07 - +1.17). An increase in psychosomatic symptoms (GHQ A mean difference = 0.22, 95% CI = -0.03 - +0.47) is considered to result from the adverse conditions, but it is not supported by other mental ill health markers. In conclusion, there appeared to be no negative effect on mental health from deployment to Afghanistan.

Physical and mental health costs of traumatic war experiences among Civil War veterans

BACKGROUND

Hundreds of thousands of soldiers face exposure to combat during wars across the globe. The health effects of traumatic war experiences have not been adequately assessed across the lifetime of these veterans.

OBJECTIVE

To identify the role of traumatic war experiences in predicting postwar nervous and physical disease and mortality using archival data from military and medical records of veterans from the Civil War.

DESIGN

An archival examination of military and medical records of Civil War veterans was conducted. Degree of trauma experienced (prisoner-of-war experience, percentage of company killed, being wounded, and early age at enlistment), signs of lifetime physician-diagnosed disease, and age at death were recorded.

SETTING AND PARTICIPANTS

The US Pension Board surgeons conducted standardized medical examinations of Civil War veterans over their postwar lifetimes. Military records of 17,700 Civil War veterans were matched to postwar medical records.

MAIN OUTCOME MEASURES

Signs of physician-diagnosed disease, including cardiac, gastrointestinal, and nervous disease; number of unique ailments within each disease; and mortality.

RESULTS

Military trauma was related to signs of disease and mortality. A greater percentage of company killed was associated with signs of postwar cardiac and gastrointestinal disease (incidence risk ratio [IRR], 1.34; P < .02), comorbid nervous and physical disease (IRR, 1.51; P < .005), and more unique ailments within each disease (IRR, 1.14; P < .005). Younger soldiers (<18 years), compared with older enlistees (>30 years), showed a higher mortality risk (hazard ratio, 1.52), signs of comorbid nervous and physical disease (IRR, 1.93), and more unique ailments within each disease (IRR, 1.32) (P < .005 for all), controlling for time lived and other covariates.

CONCLUSIONS

Greater exposure to death of military comrades and younger exposure to war trauma were associated with increased signs of physician-diagnosed cardiac, gastrointestinal, and nervous disease and more unique disease ailments across the life of Civil War veterans. Physiological mechanisms by which trauma might result in disease are discussed.

Quetiapine as an adjunctive treatment for post-traumatic stress disorder: an 8-week open-label study

This study evaluated the effectiveness of quetiapine for subjects with post-traumatic stress disorder (PTSD) who were already on a stable dose of a selective serotonin reuptake inhibitor (SSRI) but had significant PTSD symptoms. Fifteen subjects were enrolled in an 8-week open-label trial for PTSD in which quetiapine was added to an SSRI. Subjects were on a stable dose of the SSRI for at least 6 weeks before study entry and had a Clincian-Administered PTSD Scale (CAPS) score of greater than or equal to 50 at study baseline. The mean age of subjects was 49 years (eight men and seven women). The average duration of PTSD was 29 years, one-third of subjects had combat-related PTSD, and two-thirds had noncombat PTSD. The mean dose prescribed in the study was 216 mg per day. The initial median CAPS score was 80, indicating severe PTSD. The addition of a modest dose of quetiapine provided significant relief from PTSD symptoms with a 42% overall improvement in PTSD symptoms based on the CAPS and significant improvement along each dimension of symptoms: re-experiencing (Z=-3.24, P=0.0012), hyperarousal (Z=-3.30, P=0.001) and avoidance (Z=-2.13, P=0.03). Subjects rated themselves as 45% improved on average on the Davidson Trauma Scale and reported a 44% decrease in their level of disability and impairment as reflected by the Sheehan Disability Scale. Subjects with PTSD who had significant PTSD symptoms when on an SSRI benefited from the addition of quetiapine. Patients improved significantly on all three clusters of PTSD symptoms: re-experiencing, hyperarousal and avoidance.

The bane of "inhumane" weapons and overkill: an overview of increasingly lethal arms and the inadequacy of regulatory controls

Weapons of both defense and offense have grown steadily in their effectiveness--especially since the industrial revolution. The mass destruction of humanity, by parts or in whole, became reality with the advent of toxic agents founded on chemistry and biology or nuclear weapons derived from physics. The military's new non-combat roles, combined with a quest for non-lethal weapons, may change the picture in regard to conventional defense establishments but are unlikely to deter bellicose tyrants or the new terrorists from using the unlimited potential of today's and tomorrow's arsenals. The author addresses the issues that are raised by this developing situation with the intent of seeking those ethics that will enable us to survive in a future and uncertain world.

Serum lipid concentrations in Croatian veterans with post-traumatic stress disorder,post-traumatic stress disorder comorbid with major depressive disorder,or major depressive disorder

The aim of this study was to assess eventual differences in serum cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides, LDL-C/HDL-C ratio between veterans with combat-related post-traumatic stress disorder (PTSD) only or comorbid with major depressive disorder (MDD), veterans with combat experiences with MDD, and healthy control group. PTSD and/ or MDD were diagnose according to structured clinical interview based on DSM-IV criteria. Additional criteria to diagnose PTSD were Clinician Administered PTSD Scale (CAPS), and to diagnose MDD Montgomery-Asberg Depression Rating Scale (MADRAS). Serum lipid concentrations were determined by using the enzyme-assay method. Veterans with combat-related PTSD as well as veterans with combat-related PTSD comorbid with MDD showed significantly higher concentrations of cholesterol (F=9.858, p<0.01), triglycerides (F=10.112, p<0.01), LDL-C (F=11.145, p<0.01), and LDL-C/HDL-C ratio (F=8.346, p<0.01) vs. veterans with MDD or healthy control group. Contrary healthy control group and veterans with MDD showed significantly higher concentrations of HDL-C (F=8.421, p<0.01), vs. veterans with PTSD or PTSD comorbid with MDD. In conclusion, there are no differences in serum lipid concentrations between veterans with combat-related PTSD and PTSD comorbid with MDD, but they have higher lipid concentrations than veterans with MDD or healthy control subjects.

[Historical evolution of the concept of posttraumatic stress disorder]

The authors elaborate on the historical evolution of the concept of Posttraumatic Stress Disorder (PTSD). The authors quote the French scholars, mainly Charcot and Janet, as the first to connect traumatic events and symptoms of hysteria. The contributions of Freud are described with enphasis on his effort into integrating the intra-psychic and environmental dimensions. Kardiner is referred as the author who coined the concept of 'war neurosis', which was deemed as an important one during the Second World War and Vietnam War. In conclusion, the authors highlight that the concept of PTSD used in the Diagnostic and Statistical Manual of Mental Disorders (DSM) by the American Psychiatric Association assess, at the same time, how treatening was the traumatic event and the list of symptoms presented by the patients.

Ambulatory monitoring and physical health report in Vietnam veterans with and without chronic posttraumatic stress disorder

This study investigated the associations among PTSD, ambulatory cardiovascular monitoring, and physical health self-reports in 117 male Vietnam combat veterans (61 with PTSD and 56 without PTSD). PTSD was associated with health symptoms and number of current health conditions beyond the influence of several covariates. PTSD was associated with greater systolic blood pressure variability, and an elevated percentage of heart rate and systolic blood pressure readings above baseline. Higher mean heart rate and an elevated percentage of heart rate above baseline were associated with physical health symptoms. None of the ambulatory monitoring variables mediated the association between PTSD and physical health outcomes. Findings suggest that the interrelationships among ambulatory autonomic responses, PTSD, and physical health deserve more research attention.

War syndromes and their evaluation: from the U.S. Civil War to the Persian Gulf War

PURPOSE

To better understand the health problems of veterans of the Persian Gulf War by analyzing previous war-related illnesses and identifying possible unifying factors.

DATA SOURCE

English-language articles and books on war-related illnesses published since 1863 that were located primarily through a manual search of bibliographies.

DATA EXTRACTION

Publications were assessed for information on the clinical characteristics of war-related illnesses and the research methods used to evaluate such illnesses.

DATA SYNTHESIS

Poorly understood war syndromes have been associated with armed conflicts at least since the U.S. Civil War. Although these syndromes have been characterized by similar symptoms (fatigue, shortness of breath, headache, sleep disturbance, forgetfulness, and impaired concentration), no single recurring illness that is unrelated to psychological stress is apparent. However, many types of illness were found among evaluated veterans, including well-defined medical and psychiatric conditions, acute combat stress reaction, post-traumatic stress disorder, and possibly the chronic fatigue syndrome. No single disease is apparent, but one unifying factor stands out: A unique population was intensely scrutinized after experiencing an exceptional, life-threatening set of exposures. As a result, research efforts to date have been unable to conclusively show causality, have been subject to reporting bias, and have lacked similar control populations. In addition to research limitations, war syndromes have involved fundamental, unanswered questions about the importance of chronic somatic symptoms and the factors that create a personal sense of ill health.

CONCLUSION

Until we can better understand what constitutes health and illness in all adult populations, we risk repeated occurrences of unexplained symptoms among veterans after each war.

Psychiatric casualties in the Pacific during World War II: servicemen hospitalised in a Brisbane mental hospital

World War II created many psychiatric casualties but precise incidences were not accurately established. Battle shock was under-reported as some commanding officers were reluctant to admit that their men experienced battle stress. The objective in triage of any casualties was to retain as many patients in the war zone as possible, if further useful service was feasible. This also applied to soldiers with stress-related symptoms, who were treated in base hospitals as near to an operational zone as possible. The main treating maxims were "immediacy, proximity and expectancy", which involved rapid early treatment in the war zone, hoping for an early return to duty (which often meant active duty). Only those with severe psychiatric illness were sent back to their home country. The medical officer had to be sure that the patient had not responded to treatment before sending him home. During the war, the terminology used for psychological responses to the stress of combat was derived from several classifications in textbooks. Psychiatric nomenclature, barely adequate for civilian psychiatry, was totally inadequate for military psychiatry during that period. The aim of classification was to facilitate data collection rather than to provide definitive diagnoses. Psychiatric therapies during World War II were, at least to some degree, diagnostically non-specific. Diagnosis varied according to the soldier's proximity to the war zone (i.e., less severe diagnoses were given to men closer to the frontline, who would be required in battle). In addition, as psychiatrists were rarely available, medical officers without relevant (or having only limited) specialty training usually diagnosed and treated soldiers with psychiatric problems. At the beginning of the war, traumatic psychiatric reactions were classified into psychoneurosis, anxiety state and anxiety reaction, psychoneurosis mixed, and conversion hysteria. By the end of the war, the United States Surgeon General released a revised nomenclature with two new diagnostic categories: transient personality reactions to acute and special stress; and neurotic-type reactions to routine military stress. It was not until the 1950s that formal criteria for the diagnosis of trauma appeared, in the first diagnostic and statistical manual (DSM-I) of the American Psychiatric Association.

[Secondary traumatization among wives of soldiers with combat stress reaction]

While the long-term effects of war-related psychic trauma on veterans have been studied extensively, the impact of the results of the trauma on wives has received only minimal attention. The implications of combat-induced stress reaction and post-traumatic stress disorder were examined in a sample of 212 wives of Israeli veterans of the 1982 Lebanon War. Both types of reaction in husbands were found to be associated with increased psychiatric and somatic symptoms in their wives.

'Low intensity' war and mental trauma in Nicaragua: a study in a rural community

'Low intensity' warfare, with its key psychological element, aimed to terrorize the rural population of Nicaragua during the 1980s. A survey of ex-refugees still living in the war zone revealed 62% of men and 91% of women as 'cases' of psychological disturbance on the General Health Questionnaire. Somatization was central to the subjective experience and communication of the distress caused by the Contra war. Sustained sleep disturbance, hyperalertness and other anxiety-based symptomatology and poor concentration were very common and were exacerbated by war-related cues. 25% of men and 50% of women merited a diagnosis of posttraumatic stress disorder. Some distress reflected unresolved grief states. The longer term mental and social costs of terrorization have been insufficiently documented in the Third World.

A knowledge assessment of combat stress reaction in Army Family Practice residents

Combat stress reaction occurs when a soldier's ability to function effectively is impaired by overwhelming stressors in a combat environment. During recent wars, Combat stress reaction has accounted for 30% to 40% of all casualties. Army Family Physicians can expect to be assigned to frontline medical units in time of war and, therefore, should be able to accurately diagnose and treat combat stress reaction. This paper reports an investigation of the knowledge Army Family Practice residents have of combat stress reaction.

Lessons learned and forgotten: the need for prevention and mental health interventions in disaster preparedness

Human beings have been subjected to the effects of both natural and man-made disasters for centuries. How humans have coped with catastrophes has been recorded through history. This review proceeds from an examination of the efforts in legislation and disaster research through a brief history of war-time experiences and treatment of combat stress reactions. As warfare changed, so did the ability of soldiers to cope. Likewise, treatment interventions to restore soldiers to effectiveness evolved with the changes in warfare. The treatment principles developed in war and the concepts recognized from the stress literature can be integrated to understand how the treatment interventions work. Examples of the delivery of mental health services are reviewed. The lesson learned during war were often forgotten after the war. It was not until the 1970s that the need for prevention and planning for mental health interventions during and after disasters was legislated. Research efforts are now focusing on planning, implementing interventions, and following survivors/victims for posttraumatic effects.
