Differential methylation of linoleic acid pathway genes is associated with PTSD symptoms - a longitudinal study with Burundian soldiers returning from a war zone. Transl Psychiatry 2024; 14:32.

Abstract
Soldiers may be exposed to traumatic stress during combat deployment and thus are at risk for developing posttraumatic stress disorder (PTSD). Genetic and epigenetic evidence suggests that PTSD is linked to forming stress-related memories. In the current study, we investigated post-deployment associations of PTSD symptoms with differential DNA methylation in a sample of Burundian soldiers returning from the African Union Mission in Somalia's war zone. We used a matched longitudinal study design to explore epigenetic changes associated with PTSD symptoms in N = 191 participants. PTSD symptoms and saliva samples were collected at 1-3 (t1) and 9-14 months (t2) after the return of the soldiers to their home base. Individuals with either worsening or improving PTSD symptoms were matched for age, stressful, traumatic and self-perpetrated events prior to the post-assessment, traumatic and violent experiences between the post- and the follow-up assessment, and violence experienced during childhood. A mixed model analysis was conducted to identify top nominally significantly differentially methylated genes, which were then used to perform a gene enrichment analysis. The linoleic acid metabolism pathway was significantly associated with post-deployment PTSD symptoms, after accounting for multiple comparisons. Linoleic acid has been linked to memory and immune related processes in previous research. Our findings suggest that differential methylation of linoleic acid pathway genes is associated with PTSD and thus may merit closer inspection as a possible mediator of resilience.

Abstract
OBJECTIVES In March 2020, France faced a health crisis due to the COVID-19 outbreak that, like previous infectious disease crises, involved high psychological and emotional stress, a series of factors that influenced the ongoing mental health crisis. METHODS We recruited 384 respondents to complete an online questionnaire during the second month of isolation: 176 psychotherapy recipients (68 were currently attending psychiatric care) and 208 healthy controls. We measured demographic characteristics, impulsivity, aggression, hopelessness, suicidal risk, and the global level of anxiety and depression in order to estimate potential discrepancies in clinical measures across these populations. RESULTS Our results indicate that the group currently undergoing psychiatric care was prone to loneliness and social isolation. Regarding clinical and nonclinical population, there were differences in suicidal risk, depression, anxiety, and hopelessness but mainly in aggression. Regression analysis also demonstrated that aggression surprisingly influenced anxiety levels. Patients undergoing therapy compared with patients who were not displayed differences only in suicidal risk, anxiety, and hopelessness, with those undergoing therapy having higher scores. The outpatient group undergoing therapy had a significantly lower level of impulsivity. Moreover, the regression to predict anxiety and depression levels from correlated factors highlighted the potentially heightened role of aggression in predicting anxiety in the clinical group. CONCLUSION New research into stress reactions should assess other clinical signals, such as aggression, and examine preventive mental health interventions in times of crisis.

Abstract
Youth in conflict-affected regions are exposed to a multitude of traumatic events. These individuals often witness violence; experience it firsthand; and, in some cases, become perpetrators. The interplay of events shapes systematic trauma histories that may have unique implications for youths' mental health. In a cross-sectional study conducted in eastern Democratic Republic of Congo (DRC), we interviewed 295 war-affected youth (63.4% boys, Mage = 16.70 years), including former child soldiers (n = 171), regarding their traumatic experiences and mental health. Using latent class analysis, we identified four common trauma history classes categorized by (a) low exposure, (b) medium exposure, (c) high exposure, and (d) high exposure/perpetration. Across the sample, gradual increases in trauma load corresponded with increased vulnerability to posttraumatic stress disorder (PTSD) symptoms, ηp 2 = .36, and internalizing problems, ηp 2 = .12; however, only youth from the high exposure/perpetration class differed significantly from other youth in their levels of externalizing problems, ηp 2 = .13, and offending behaviors, ηp 2 = .17. A longer time in armed groups was related to a higher risk of both experiencing and perpetrating violence. The results indicate that it is not child soldier status, per se, but the perpetration of violence that reinforces a cycle of violence in conflict-affected societies by contributing to increased externalizing problems and offending behaviors. In conflict regions, integrated approaches are needed to address both trauma and externalizing problems of war-affected youth.

Abstract
War and crises cause tremendous suffering and hardship and contribute to wider problems in our globalized world (e.g., mass migration, modern slavery, poverty). Yet theoretically anchored, evidence-based tools to mitigate the negative effects and restore resilience in affected communities have remained scarce, despite costly international programs. This article presents a longitudinal trial building on evidence from psychological trauma treatment and peacebuilding. Using trauma-focused individual treatment combined with a community-based intervention, we show that ignominious social norms and attitudes can be addressed effectively with the community-based intervention and thus indirectly reduce ongoing violence. War and crises affect mental health, social attitudes, and cultural norms, which can exacerbate the state of long-term insecurity. With decades of armed conflict, the Democratic Republic of Congo is one example, and violence has become normalized in civilian settings. In this study, we tested the effectiveness of the NETfacts health system, an integrated model of evidence-based individual trauma treatment (Narrative Exposure Therapy [NET]) and a trauma-informed community-based intervention (NETfacts). Alongside changes in mental health outcomes (posttraumatic stress disorder, depression, social disapproval, and shame) we also investigated change in attitudes, including rape myth acceptance, stigmatization of survivors of sexual violence, and skepticism about the reintegration of former combatants. To test whether the additional community intervention is superior to individual NET alone, we implemented a randomized controlled design with six villages and interviewed a sample of 1,066 community members. Our results demonstrate that the NETfacts health system in comparison with NET alone more effectively reduced rape myth acceptance and with it ongoing victimization and perpetration. Community members of the NETfacts group also presented with less stigmatizing attitudes against survivors of sexual violence. Skepticism about the reintegration of former combatants declined in both groups. NETfacts appears to have increased motivation to engage in individual treatment. Synergizing the healing effects of individual and collective trauma exposure, the NETfacts health system appears to be an effective and scalable approach to correct degrading or ignominious norms and restore functioning and mental health in postconflict communities.

Abstract
Objectives Intimate Partner Violence (IPV) is a globally recognized societal problem that requires intensive research to raise public awareness. Aim Accordingly, the purpose of the study is to analyze IPV at the physical, psychological, and social aspects of abuse. Method The methodology of the study correlates IPV to the personal experiences of notable Indian writer, Meena Kandasamy, according to the autobiographical account of her abusive married life in the award-winning novel When I Hit You, which depicts the horrible treatment of women by their perpetrators within a closed sphere. To substantiate, the selected autobiographical work is compared with Lenore Edna Walker’s prominent Cycle of Violence theory, which best describes why women become victims and also the abuser’s tactics in controlling the women in a violent relationship. Results The study’s findings suggest that IPV, a serious global problem, requires government intervention and severe legal enforcement to protect women’s lives from the clutches of the abuser.

Abstract
Reintegration of ex-combatants involves multiple challenges. In addition to the trauma-related psychological sequelae, social obstacles in the community can aggravate psychopathological aggressive tendencies and lead to the continuation of violence in civilian life. However, the association between others' negative attitudes and ex-combatants' ongoing perpetration of violence remains largely unexplored. Between September 2018 and May 2019, we assessed a representative community sample of adults in Eastern DR Congo (N = 1,058) and measured trauma exposure, perpetration, mental health problems (PTSD, depression, and appetitive aggression), perceived stigma (shame, perceived lack of social acknowledgement), experienced stigma, and skepticism toward reintegration with ex-combatants. Male ex-combatants (12%, n = 129) had more past trauma and violence perpetration than other community members and a greater number of recent conflicts (including both victimization and perpetration) within the community and with strangers/organized violence. They reported more experienced stigma, more severe PTSD symptoms but were less skeptical about reintegration. Ex-combatants' ongoing violence was predicted by an interplay of the community's skepticism toward reintegration and ex-combatants' perceived and recently experienced stigma (often attributed to the armed group history) and mental health problems, in addition to lifetime traumatization. These findings promote the need for combined interventions that address individual mental health problems including aggression and collective discriminatory attitudes and behaviors.

Effective Adoption of Tablets for Psychodiagnostic Assessments in Rural Burundi: Evidence for the Usability and Validity of Mobile Technology in the Example of Differentiating Symptom Profiles in AMISOM Soldiers 1 Year After Deployment. Front Public Health 2021; 9:490604.

Abstract
Research on the use of mobile technology in health sciences has identified several advantages of so-called mHealth (mobile health) applications. Tablet-supported clinical assessments are becoming more and more prominent in clinical applications, even in low-income countries. The present study used tablet computers for assessments of clinical symptom profiles in a sample of Burundian AMISOM soldiers (i.e., African Union Mission to Somalia; a mission approved by the UN). The study aimed to demonstrate the feasibility of mHealth-supported assessments in field research in Burundi. The study was conducted in a resource-poor setting, in which tablet computers are predestined to gather data in an efficient and reliable manner. The overall goal was to prove the validity of the obtained data as well as the feasibility of the chosen study setting. Four hundred sixty-three soldiers of the AMISOM forces were investigated after return from a 1-year military mission in Somalia. Symptoms of posttraumatic stress disorder (PTSD) and depression were assessed. The used data-driven approach based on a latent profile analysis revealed the following four distinct groups, which are based on the soldiers' PTSD and depression symptom profiles: Class 1: moderate PTSD, Class 2: moderate depression, Class 3: low overall symptoms, and Class 4: high overall symptoms. Overall, the four identified classes of soldiers differed significantly in their PTSD and depression scores. The study clearly demonstrates that tablet-supported assessments can provide a useful application of mobile technology in large-scale studies, especially in resource-poor settings. Based on the data collected for the study at hand, it was possible to differentiate different sub-groups of soldiers with distinct symptom profiles, proving the statistical validity of the gathered data. Finally, advantages and challenges for the application of mobile technology in a resource-poor setting are outlined and discussed.

Abstract
BACKGROUND The impacts of social stressors on violence during the coronavirus disease 2019 (COVID-19) pandemic are unknown. We hypothesized that firearm purchases and violence would increase surrounding the pandemic. This study determined the impact of COVID-19 and shelter-in-place (SIP) orders on firearm purchases and incidents in the United States (US) and New York State (NYS). METHODS Scatterplots reflected trends in firearm purchases, incidents, and deaths over a 16-month period (January 2019 to April 2020). Bivariate comparisons of SIP and non-SIP jurisdictions before and after SIP (February 2020 vs. April 2020) and April 2020 vs. April 2019 were performed with the Mann-Whitney U test. RESULTS The incidence of COVID-19 in the US increased between February and April 2020 from 24 to 1 067 660 and in NYS from 0 to 304 372. When comparing February to March to April in the US, firearm purchases increased 33.6% then decreased 22.0%, whereas firearm incidents increased 12.2% then again increased by 3.6% and firearm deaths increased 23.8% then decreased in April by 3.8%. In NYS, comparing February to March to April 2020, firearm purchases increased 87.6% then decreased 54.8%, firearm incidents increased 110.1% then decreased 30.8%, and firearm deaths increased 57.1% then again increased by 6.1%. In both SIP and non-SIP jurisdictions, April 2020 firearm purchases, incidents, deaths, and injuries were similar to April 2019 and February 2020 (all P = NS). DISCUSSION Coronavirus disease 2019-related stressors may have triggered an increase in firearm purchases nationally and within NYS in March 2020. Firearm incidents also increased in NYS. SIP orders had no effect on firearm purchases and firearm violence.
