RESUMO
OBJECTIVE: The risk of suicide in contemporary serving and ex-serving Australian Defence Force personnel is an area of significant concern, driving government-directed inquiries, community campaigns and most recently, the establishment of a permanent National Commissioner for Defence and Veteran Suicide Prevention. This concern is mirrored in international militaries and despite investment in prevention programmes, suicide is a leading cause of death in military populations. This review seeks to summarise recent findings from Australian research regarding the magnitude and factors associated with suicide and suicidality in contemporary serving and ex-serving Australian Defence Force populations and discusses research findings, implications and future opportunities. METHODS: Initial review of the prevalence of suicide and suicidality in the general community and military populations is presented, followed by review of recent research findings pertaining to suicides and suicidal thoughts, plans and attempts in contemporary serving and ex-serving Australian Defence Force personnel. Key findings are presented from the 2010 Australian Defence Force Mental Health and Wellbeing Prevalence Study and the 2015 Transition and Wellbeing Research Programme. RESULTS: Differences between serving and ex-serving Australian Defence Force cohorts were observed, with rates of completed suicide in ex-serving Australian Defence Force males more than double that of serving Australian Defence Force males, and increased risk for suicidality observed among those who had recently transitioned out of full-time Australian Defence Force service. Risk for increased suicidality and completed suicide is particularly evident for younger males of lower ranks, and those who have been medically discharged. CONCLUSIONS: The findings provide insight into career phases and groups that should be followed-up and targeted for prevention and early intervention programmes, including prior to and several years following transition out of full-time military service. Further research to better understand the factors that influence those who develop suicidal ideation, and those who progress to plans and attempts, will inform a more sophisticated approach to suicide prevention programmes.

Post-traumatic stress disorder (PTSD) is one of the common mental disorders in military and veteran populations. Considerable research and clinical opinion has been focused on understanding the relationship between PTSD and military service and the implications for prevention, treatment, and management. This paper examines factors associated with the development of PTSD in this population, considers issues relating to engagement in treatment, and discusses the empirical support for best practice evidence-based treatment. The paper goes on to explore the challenges in those areas, with particular reference to treatment engagement and barriers to care, as well as treatment non-response. The final section addresses innovative solutions to these challenges through improvements in agreed terminology and definitions, strategies to increase engagement, early identification approaches, understanding predictors of treatment outcome, and innovations in treatment. Treatment innovations include enhancing existing treatments, emerging non-trauma-focused interventions, novel pharmacotherapy, personalized medicine approaches, advancing functional outcomes, family intervention and support, and attention to physical health.

OBJECTIVE: This commentary highlights challenges and opportunities in suicide prevention across the military and veteran populations of the Five Eyes nations. METHODS: Trends in suicides and suicidality in military and veteran populations are outlined, as well as identified risk and protective factors, and approaches to suicide prevention. RESULTS: Suicide risk is higher in veterans compared to current serving and community samples. Despite extensive research, the causation, prediction, and prevention of suicide, is still not well understood. We propose areas for further attention in prevention strategies. CONCLUSION: Suicide and suicidality are issues of concern in military and veteran populations. Suicide prevention requires commitment to continuous improvement through research, analysis, and incorporation of evolving best practice.

First responders experience mental health conditions at a higher rate than the general population. To improve treatment and enhance quality of care, it is important to understand the needs of those who provide mental health treatment to this population. The purpose of this study was to explore the needs of mental health providers with experience working with first responders to better understand how first responders differ from community patients, and what training and supports providers need to enhance treatment. Semistructured qualitative interviews were conducted via videocalls with 12 mental health providers who provide mental health care to Australian first responders. The interviews were transcribed verbatim and interpretative phenomenological analysis was performed. The findings highlighted the importance of identity and culture among first responders, and the need for cultural awareness and understanding among mental health providers working with this population. Various training opportunities which could enhance treatment capacities were identified, including training in accurate assessment and differential diagnosis, evidence-based trauma-focused treatments, transdiagnostic treatments, and working with specific first responder treatment characteristics (e.g., emotional detachment, rigid cognitive styles, and preferences toward structure and order). Ways in which mental health providers can be supported included facilitating professional networks between providers and connection with first responder organizations. The insights gathered from this study provide a foundation from which to consider training and support development for mental health providers working with first responders. Service level implications and directions are outlined to assist future decision making on this topic. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

OBJECTIVE: This study investigated associations between gambling problems and suicidality in Australian veterans. METHODS: Data drawn from n = 3,511 Australian Defence Force veterans who had recently transitioned to civilian life. Gambling problems were assessed using the Problem Gambling Severity Index (PGSI) and suicidal ideation and behaviour were assessed using items adapted from the National Survey of Mental Health and Wellbeing. RESULTS: At-risk gambling and problem gambling were associated with increased odds of suicidal ideation [at-risk gambling: odds ratio (OR), 1.93; 95% confidence interval (CI), 1.47â2.53; problem gambling: OR, 2.75; 95% CI 1.86â4.06] and suicide planning or attempts (at-risk gambling: OR, 2.07; 95% CI, 1.39â3.06; problem gambling: OR 4.22, 95% CI, 2.61â6.81). The association with total scores on the PGSI and any suicidality was substantially reduced and became non-significant when controlling for the effects of depressive symptoms, but not financial hardship or social support. CONCLUSIONS: Gambling problems and harms are important risk factors for suicide in veterans, and should be recognised in veteran-specific suicide prevention policies and programs, along with co-occurring mental health problems. IMPLICATIONS FOR PUBLIC HEALTH: A comprehensive public health approach to reducing gambling harm should feature in suicide prevention efforts in veteran and military populations.

BACKGROUND: Problem anger is increasingly identified as an important issue, and may be associated with suicidality and violence. This study investigates the relationship between problem anger, suicidality, and violence amongst veterans and military personnel. METHODS: Cross-sectional survey data from n = 12,806 military personnel and veterans were subject to analyses. These considered the weighted prevalence of problem anger, while further analyses of veterans (n = 4326) considered risk factors and co-occurrence with other psychiatric conditions. Path analyses examined inter-relationships involving anger, violence and suicidality. RESULTS: There were 30.7% of veterans and 16.4% of military personnel that reported past month problem anger, while 14.9% of veterans and 7.4% of military personnel reported physical violence. There were higher levels of suicidality among veterans (30.3%), than military personnel (14.3%). Logistic regression models indicated that PTSD was the strongest risk factor for problem anger (PCL-5, OR = 21.68), while there were small but substantial increases in anger rates associated with depression (OR = 15.62) and alcohol dependence (OR = 6.55). Path models indicated that problem anger had an influence on suicide attempts, occurring primarily through suicidal ideation, and an influence on violence. Influences of problem anger on suicidal ideation and violence remained significant when controlling for co-occurring mental health problems. CONCLUSIONS: Problem anger, violence, and suicidality are common and inter-related issues among military personnel and veterans. Problem anger is a unique correlate of suicidality, supporting the need for anger to be included as part of violence and suicide risk assessment, and clinician training.

BACKGROUND AND AIMS: Veterans who have recently left the military (i.e., transitioned) may be vulnerable to the development of psychiatric disorders, but little is known about gambling problems in this population. This study investigated the prevalence and risk factors of gambling problems, help-seeking amongst veterans with gambling problems, and relationships with trauma and posttraumatic psychopathology. METHODS: Cross-sectional self-report survey data from 3,511 Australian Defence Force members who left the military within the past five years. Surveys included measures of gambling problems (PGSI); depressive symptoms (PHQ-9); posttraumatic stress disorder (PCL-5); help-seeking behaviours; military and non-military-related trauma. RESULTS: Prevalence rates for problem gambling (PGSI ≥ 5) were 4.6%, while an additional 8.8% were classified in terms of at-risk gambling (PGSI = 1-4). Time since leaving the military was not associated with gambling problems. Only 2.1% of veterans with problem gambling reported help-seeking for their gambling. While trauma exposure, depression, and Posttraumatic Stress Disorder (PTSD) were all related to gambling problems at the bivariate level, only arousal and dysphoric-related affect were uniquely associated with gambling problems when adjusting for covariates. DISCUSSION: Gambling problems may be under-recognised relative to other psychiatric issues. Posttraumatic mental health problems, rather than trauma exposure per se, may explain the relationship between trauma and gambling problems. CONCLUSIONS: Some veterans are in a period of vulnerability during transition out of military service, and harms associated with gambling problems may be exacerbated during this period.

Military service is associated with increased risk of mental health problems. Previous reviews have pointed to under-utilization of mental health services in military populations. Building on the most recent systematic review, our narrative, critical review takes a complementary approach and considers research across the Five-Eyes nations from the past six years to update and broaden the discussion on pathways to mental healthcare in military populations. We find that at a broad population level, there is improvement in several indicators of mental health care access, with greater gains in initial engagement, time to first treatment contact, and subjective satisfaction with care, and smaller gains in objective indicators of adequacy of care. Among individual-level barriers to care-seeking, there is progress in improving recognition of need for care and reducing stigma concerns. Among organizational-level barriers, there are advances in availability of services and cultural acceptance of care-seeking. Other barriers, such as concerns around confidentiality, career impact, and deployability persist, however, and may account for some remaining unmet need. To address these barriers, new initiatives that are more evidence-based, theoretically-driven, and culturally-sensitive, are therefore needed, and must be rigorously evaluated to ensure they bring about additional improvements in pathways to care.

The transition period from military-to-civilian life can be one of the most significant and stressful periods in the military life cycle. We explore the psychosocial factors associated with psychological distress and functional impairment among those who recently transitioned from the Australian Defence Force (ADF) and those currently serving in 2015. Using data from the Transition and Wellbeing Research Programme, multinomial logistic regression models were used to analyze the associations between a combined measure of psychological distress and functional impairment (K10/SDS) with various psychosocial, lifestyle, and physical health factors. There were 10,210 in the final analytic cohort (Transitioned=3,254; Regular 2015 ADF=6,956). Overall, the odds of belonging to the highly distressed/impaired group were greatest among those with insomnia (Odds Ratio 18.53), low resilience (OR 7.67), physical health symptoms (OR 7.16), and alcohol risk (OR 4.67). Other factors included pain (OR 3.36), financial issues (OR 2.38), and social strain (OR 1.98). The associations with insomnia and physical health symptoms were stronger among the Transitioned compared to the Regular 2015 ADF. Results of this research highlights the importance of taking a multi-dimensional perspective of symptoms in military populations, particularly in those recently transitioned from permanent service, as predictors of future risk of disorder.
RESUMO
Military and veteran populations may exhibit heightened vulnerability to gambling problems; however, there is scant relevant evidence outside the US, and few studies of transition periods, including return from operational deployment. The aim of this study was thus to highlight the extent, risk-factors, and implications of gambling problems among current members of the Australian Defence Force (ADF) following deployment to the Middle East Area of Operations (MEAO). It involved analyses of data from n = 1324 ADF personnel who deployed between 2010 and 2012, and completed surveys within four months of returning to Australia. The Problem Gambling Severity Index (PGSI) identified Problem Gambling (PG: PGSI ≥5) and At-Risk Gambling (ARG: PGSI 1-4), alongside measures of Depression (PHQ-9), Posttraumatic Stress Disorder (PCL-C), alcohol use problems (AUDIT), distress (K10), and post-deployment stressors. Analyses indicated that 7.7% of personnel reported at least some gambling problems post-deployment, including 2.0% that were distinguished by PG, and 5.7% indicating ARG. These figures were comparable to conditions including probable depression and alcohol dependence, while levels of any gambling problems were high relative to harmful drinking. Higher levels were observed among personnel who were aged 18-24, reported 0-4 years of military service, served in the Army, and comprised Non-Commissioned Officers/Other Ranks. There were strong associations with gambling problems and various indicators of mental health and wellbeing, and self-reported post-deployment difficulties. The findings indicate that gambling problems are salient concerns for some Australian military personnel post-deployment, and highlight the need for increased recognition and responses to these problems.

Two similar mycobacteria, Mycobacteria tuberculosis H37Ra and Mycobacteria smegmatis are rapidly detected and identified within samples containing a complex background of respiratory effluents using single-particle aerosol mass spectrometry (SPAMS). M. tuberculosis H37Ra (TBa), an avirulent strain, is used as a surrogate for virulent tuberculosis; M. smegmatis (MSm) is utilized as a near-neighbor confounder for TBa. Bovine lung surfactant and human exhaled breath condensate are used as first-order surrogates for infected human lung expirations from patients with pulmonary tuberculosis. This simulated background sputum is mixed with TBa or MSm and nebulized to produce conglomerate aerosol particles, single particles that contain a bacterium embedded within a background respiratory matrix. Mass spectra of single conglomerate particles exhibit ions associated with both respiratory effluents and mycobacteria. Spectral features distinguishing TBa from MSm in pure and conglomerate particles are shown. SPAMS pattern matching alarm algorithms are able to distinguish TBa-containing particles from background matrix and MSm for >50% of the test particles, which is sufficient to enable a high probability of detection and a low false alarm rate if an adequate number of such particles are present. These results indicate the potential usefulness of SPAMS for rapid, reagentless tuberculosis screening.

Multiple myeloma (MM) is an incurable malignancy of the plasma cells localized to the bone marrow. A rare population of MM cancer stem cells (MM-CSCs) has been shown to be responsible for maintaining the pull of residual disease and to contribute to myeloma relapse. The stem cells are found in a bone marrow niche in contact with the stromal cells that are responsible for maintaining the proliferative quiescence of the MM-CSC and regulate its self-renewal and differentiation decisions. Here we show that both MM and bone marrow stromal cells express N-cadherin, a cell-cell adhesion molecule shown to maintain a pool of leukemic stem cells. Inhibition of N-cadherin using a neutralizing antibody led to an increase in the MM cell proliferation. A decrease in MM cell adhesion to the bone marrow stroma was observed in the first 24 hours of co-culture followed by a 2.3-30-fold expansion of the adherent cells. Moreover, inhibition of N-cadherin led to a 4.8-9.6-fold expansion of the MM-CSC population. Surprisingly, addition of the N-cadherin antagonist peptide resulted in massive death of the non-adherent MM cells, while the viability of the adherent cells and MM-CSCs remained unaffected. Interestingly, the proliferative effects of N-cadherin inhibition were not mediated by the nuclear translocation of ß-catenin. Taken together, our findings demonstrate the crucial role of N-cadherin in regulating MM cell proliferation and viability and open an interesting avenue of investigation to understand how structural modifications of N-cadherin can affect MM cell behavior. Our findings suggest that targeting N-cadherin may be a useful therapeutic strategy to treat MM in conjunction with an agent that has anti-MM-CSC activity.
