Association Between Responsibility for the Death of Others and Postdeployment Mental Health and Functioning in US Soldiers

Next-generation precision medicine for suicidality prevention

Suicidality remains a clear and present danger in society in general, and for mental health patients in particular. Lack of widespread use of objective and/or quantitative information has hampered treatment and prevention efforts. Suicidality is a spectrum of severity from vague thoughts that life is not worth living, to ideation, plans, attempts, and completion. Blood biomarkers that track suicidality risk provide a window into the biology of suicidality, as well as could help with assessment and treatment. Previous studies by us were positive. Here we describe new studies we conducted transdiagnostically in psychiatric patients, starting with the whole genome, to expand the identification, prioritization, validation and testing of blood gene expression biomarkers for suicidality, using a multiple independent cohorts design. We found new as well as previously known biomarkers that were predictive of high suicidality states, and of future psychiatric hospitalizations related to them, using cross-sectional and longitudinal approaches. The overall top increased in expression biomarker was SLC6A4, the serotonin transporter. The top decreased biomarker was TINF2, a gene whose mutations result in very short telomeres. The top biological pathways were related to apoptosis. The top upstream regulator was prednisolone. Taken together, our data supports the possibility that biologically, suicidality is an extreme stress-driven form of active aging/death. Consistent with that, the top subtypes of suicidality identified by us just based on clinical measures had high stress and high anxiety. Top therapeutic matches overall were lithium, clozapine and ketamine, with lithium stronger in females and clozapine stronger in males. Drug repurposing bioinformatic analyses identified the potential of renin-angiotensin system modulators and of cyclooxygenase inhibitors. Additionally, we show how patient reports for doctors would look based on blood biomarkers testing, personalized by gender. We also integrated with the blood biomarker testing social determinants and psychological measures (CFI-S, suicidal ideation), showing synergy. Lastly, we compared that to machine learning approaches, to optimize predictive ability and identify key features. We propose that our findings and comprehensive approach can have transformative clinical utility.

The adaptation of soldiers to post-service life - the mediating impact of political views on the relationship between violence and adaptation

Introduction

The current research explores the association between political views, combat experiences, and the adaptation of soldiers to post-service life. Violent experiences in military service were explored as contributors to both positive and negative dimensions of adaptation, while political views served as possible mediators.

Methods

Three hundred and twenty Israeli veterans participated in the study.

Results

Political views were correlated with adaptation, especially left-to-right voting and anti-militarism. The results support the mediating role of political beliefs (left-right voting and militarism) in the relationship between combat experience and adaptation to post-service life.

Discussion

We contend that political perceptions affect adaptation through sense-making of the combat experiences and the individual processing of these experiences, and the willingness to continue in reserve service, which allows social support and recognition. In addition, they are linked to a sense of bitterness following the reduction of public participation in military and reserve service.

Prospective Association of Unmet Mental Health Treatment Needs With Suicidal Behavior Among Combat-Deployed Soldiers

OBJECTIVE

Military personnel frequently report discontinuing or not pursuing psychiatric treatment despite perceiving a need for services. This study aimed to examine how unmet need for treatment or support among U.S. Army soldiers relates to future suicidal ideation (SI) or suicide attempt (SA).

METHODS

Mental health treatment need and help seeking in the past 12 months were evaluated for soldiers (N=4,645) who subsequently deployed to Afghanistan. Weighted logistic regression models were used to examine the prospective association of predeployment treatment needs with SI and SA during and after deployment, with adjustment for potential confounders.

RESULTS

Compared with soldiers without predeployment treatment needs, those who reported not seeking help despite needing it had increased risk for SI during deployment (adjusted OR [AOR]=1.73), past-30-day SI at 2-3 months postdeployment (AOR=2.08), past-30-day SI at 8-9 months postdeployment (AOR=2.01), and SA through 8-9 months postdeployment (AOR=3.65). Soldiers who sought help and stopped treatment without improvement had elevated SI risk at 2-3 months postdeployment (AOR=2.35). Those who sought help and stopped after improving did not have increased SI risk during or 2-3 months after deployment but had elevated risks for SI (AOR=1.71) and SA (AOR=3.43) by 8-9 months postdeployment. Risks for all suicidality outcomes were also elevated among soldiers who reported receiving ongoing treatment before deployment.

CONCLUSIONS

Unmet or ongoing needs for mental health treatment or support before deployment are associated with increased risk for suicidal behavior during and after deployment. Detecting and addressing treatment needs among soldiers before deployment may help prevent suicidality during deployment and reintegration periods.

The Impact of Just and Unjust War Events on Mental Health Need and Utilization within U.S. Service Members

Background: Soldiers are resilient to just war events, such as killing enemy combatants and life-threatening experiences, but these same soldiers appear to struggle with unjust war events, such as killing a noncombatant or being unable to help civilian women and children in need. This study is the first to examine how just and unjust war experiences are associated with clinical health service outcomes. Methods: Two samples of soldiers in different stages of readjustment from deployment were drawn from a longitudinal, survey-based study of a US Army brigade. Measures included items related to combat events, mental health utilization, perceived mental health need, PTSD, depression, and functional impairment. Results: After controlling for other kinds of combat events, just war events (i.e., life-threatening events and killing enemy combatants) predicted outcomes in soldiers who are less than three months post-deployment, but only predicted 2 of 26 outcomes in soldiers one year post deployment. In contrast, unjust war events were found to be robust predictors of short-term and long-term outcomes related to mental health need and utilization, even after controlling for exposure to other combat events. Conclusions: The results extend previous longitudinal research that suggests that exposure to unjust war events carry a heavier long-term mental health burden than other types of events. Additionally, Soldiers exposed to unjust war events had an unmet need for care one year post deployment that was not directly tied to PTSD or depression. The results question the emphasis on life-threat within mental health pathogenesis models.

What Do You Want Us to Know?: Learning From Life Stories to Improve Veterans' Healthcare Experiences

My Life My Story (MLMS) is a national Veterans Health Administration (VA) life story interview program that aims to provide more humanistic care for veterans by focusing on the patient as a person. Our project took place at the Pittsburgh VA Healthcare System and had 3 main goals: (1) describe themes that emerge in MLMS interviews from the prompting question, what do you want your healthcare provider to know about you?; (2) identify topics of importance to veterans and suggest ways for healthcare providers to explore them; and (3) foster a culture at the Pittsburgh VA that places not only the health but also the personal triumphs, hardships, and aspirations of veterans at the center. Veterans provided verbal consent to have their previously recorded stories used in this study. Stories were coded and then analyzed for patterns and themes. A total of 17 veterans participated in our study. Themes that emerged from the stories include (1) Early Hardships; (2) Economic Disadvantage; (3) Polaroid Snapshots; (4) Around the World; (5) Haunted by Combat; (6) Life-altering Moments; (7) Homecoming; (8) Romantic Beginnings & Obstacles; (9) Inequity across Gender & Race; and (10) Facing Mortality. This study's findings underscore the need to address the traumas associated with military service, as well as the challenges faced with re-integration into civilian life, when working with veterans. The MLMS interviews explored in this study can help clinicians identify topics of importance to veterans, strengthen their relationships with their patients, and improve the care that veterans receive.
