Abstract 4134272: Association of depression symptoms with cardiovascular health stratified by military status: Insights from 2013-2020 National Health and Nutrition Examination Survey

Introduction: Emerging evidence supports the mind-heart-body connection, yet less attention has been given to examining the relationship in specific populations. Veterans have a higher risk for mental and cardiovascular problems and have unique social determinants of health (SDoH), such as healthcare access, than civilians. This study aims to examine how depression and SDoH are associated with cardiovascular health (CVH) and if associations differ by military status. Hypotheses: 1) Depression symptoms and SDoH will be associated with CVH. 2) The associations will differ between people who served in the US military and those who did not. Methods: A cross-sectional analysis was conducted using data from the 2013 to 2020 National Health and Nutrition Examination Survey. Individuals were aged ≥ 20 years without cardiovascular disease and current pregnancy. Patient Health Questionnaire-9 was used to assess depression symptoms and dichotomized into no symptoms (<5) and mild-to-severe symptoms (≥5). The Life's Essential 8 quantified CVH, with scores from 0-100. SDoH included age, gender, race/ethnicity, marital status, education, employment, financial status, health insurance, and healthcare access. Sample weights were applied in multiple linear regression analyses. Results: Among 6498 participants, 92% were civilians (mean age: 45 years; 51% female), and 8% were veterans (mean age: 56 years; 10% female). In both groups, 23% had depression symptoms. The mean CVH was 72 in civilians and 69 in veterans. In adjusted models, individuals with depression symptoms had 4 points lower CVH scores than those without (95% CI: -5.11, -2.84). This trend was similar in civilians but insignificant in veterans. Lower CVH was significantly associated with age, being non-Hispanic Black and other races people, lower education, and lower financial status. The associations were preserved after being stratified by military status. Conclusions: Depression symptoms and SDoH were associated with lower CVH. However, there was no significant evidence that military status moderated the associations of depression and SDoH with CVH. Examining the intersection between depressive symptoms and SDoH may be useful when assessing CVH.

Differences in Brain Volume in Military Service Members and Veterans After Blast-Related Mild TBI: A LIMBIC-CENC Study.

Blast-related mild traumatic brain injuries (TBIs), the "signature injury" of post-9/11 conflicts, are associated with clinically relevant, long-term cognitive, psychological, and behavioral dysfunction and disability; however, the underlying neural mechanisms remain unclear. To investigate associations between a history of remote blast-related mild TBI and regional brain volume in a sample of US veterans and active duty service members. Prospective cohort study of US veterans and active duty service members from the Long-Term Impact of Military-Relevant Brain Injury Consortium-Chronic Effects of Neurotrauma Consortium (LIMBIC-CENC), which enrolled more than 1500 participants at 5 sites used in this analysis between 2014 and 2023. Participants were recruited from Veterans Affairs medical centers across the US; 774 veterans and active duty service members of the US military met eligibility criteria for this secondary analysis. Assessment dates were from January 6, 2015, to March 31, 2023; processing and analysis dates were from August 1, 2023, to January 15, 2024. All participants had combat exposure, and 82% had 1 or more lifetime mild TBIs with variable injury mechanisms. Regional brain volume was calculated using tensor-based morphometry on 3-dimensional, T1-weighted magnetic resonance imaging scans; history of TBI, including history of blast-related mild TBI, was assessed by structured clinical interview. Cognitive performance and psychiatric symptoms were assessed with a battery of validated instruments. We hypothesized that regional volume would be smaller in the blast-related mild TBI group and that this would be associated with cognitive performance. A total of 774 veterans (670 [87%] male; mean [SD] age, 40.1 [9.8] years; 260 [34%] with blast-related TBI) were included in the sample. Individuals with a history of blast-related mild TBI had smaller brain volumes than individuals without a history of blast-related mild TBI (which includes uninjured individuals and those with non-blast-related mild TBI) in several clusters, with the largest centered bilaterally in the superior corona radiata and subcortical gray and white matter (cluster peak Cohen d range, -0.23 to -0.38; mean [SD] Cohen d, 0.28 [0.03]). Additionally, causal mediation analysis revealed that these volume differences significantly mediated the association between blast-related mild TBI and performance on measures of working memory and processing speed. In this cohort study of 774 veterans and active duty service members, robust volume differences associated with blast-related TBI were identified. Furthermore, these volume differences significantly mediated the association between blast-related mild TBI and cognitive function, indicating that this pattern of brain differences may have implications for daily functioning.

Addressing US Military Transgender Care Inequalities: Clinical Nurse Specialist Bridging Healthcare Gaps.

There are more than 130 000 US veterans and more than 12 500 active-duty service members who identify as transgender. Lack of training in transgender and gender-affirming care among healthcare providers in the military is still reported. The article aims to explore and advocate for the unique role of advanced practice registered nurses, especially clinical nurse specialists, in providing culturally sensitive and evidence-based care to the transgender population within the US military. The clinical nurse specialists' pivotal role in policy advocacy and translation of evidence to improve the quality of care and patient outcomes for transgender service members is highlighted. The article also explores the historical journey of transgender care in the US military, addressing discriminatory policies and the implications of the ever-evolving regulations in military transgender healthcare. The article aims to create awareness of clinical nurse specialist utilization in US military healthcare services to improve the care of transgender individuals in the military. The uncertain future for transgender service members highlights the ongoing commitment needed to navigate complex military healthcare policies and foster inclusive, evidence-based practices. Therefore, the clinical nurse specialist plays a pivotal role in shaping the future of transgender healthcare within the US military.

Veterans Day: Pausing to Honor the Leadership of Military Nurses.

Spinal Injuries and Spine Care in the US Military Health System (2001-Present).

Literature Review. The goal of this study was to provide a comprehensive outline of spinal injuries that may transpire over the course of military service from traumatic to repetitive stress injuries and chronic sequalae. We considered studies that assessed spinal injuries in the combat and non-combat settings as reported in the literature over the last 15-20 years. Military service places servicemembers under substantial physical demands, while also exposing them to dangerous, unpredictable environments. As a result, servicemembers are at an increased risk of spinal injuries from combat-related trauma and other causes. They may have different care needs and recovery profiles when compared to civilians with spinal disorders. We performed a review of the available literature on spinal injuries and spinal care in the Military Health System from 2001-present. The studies discussed in this review were primarily focused on the conflicts in both Iraq and Afghanistan from over ten years ago and do not fully capture the present-day advancements in military technology that may have an impact on the potential for spinal injuries. The long-term effects of sustained military service and the relative influence of high demand versus sedentary military occupations on the development of spinal disorders remains poorly understood. Given the changing nature of military service, both with respect to the demographic in uniform and the ever-evolving nature of modern combat, we believe that only a long-term prospective observational study dedicated to the surveillance of spinal problems could effectively answer these questions. Further research into the present-day characterization of spinal injuries is warranted given the advancements in both military technology and spine care that have occurred over the last ten years.

Posttraumatic Stress Disorder, Obesity, and Accelerated Epigenetic Aging Among US Military Veterans

This cross-sectional study uses data from 1135 male, European-American US military veterans to assess whether risk and protective factors influenced associations between posttraumatic stress disorder and epigenetic age.

Short-Term Outcomes of a Healthy Relationship Intervention for the Prevention of Sexual Harassment and Sexual Assault in the US Military: Pilot Pretest-Postest Study.

Sexual harassment (SH) and sexual assault (SA) are serious public health problems among US service members. Few SH and SA prevention interventions have been developed exclusively for the military. Code of Respect (X-CoRe) is an innovative web-based, multilevel, SA and SH intervention designed exclusively for the active-duty Air Force. The program's goal is to increase Airmen's knowledge and skills to build and maintain respectful relationships, ultimately reducing SH and SA and enhancing Airmen's overall well-being and mission readiness. This pilot study aimed to assess the short-term psychosocial impact (eg, knowledge, attitudes, and self-efficacy) of the web-based component of X-CoRe on a sample of junior enlisted and midlevel Airmen. Airmen from a military installation located in the Northeastern United States were recruited to complete the 10 web-based modules in X-CoRe (9/15, 60% male; 7/15, 54% aged 30-35 years). Participants were given pretests and posttests to measure short-term psychosocial outcomes associated with SH and SA. Descriptive statistics and paired 2-tailed t tests were conducted to assess differences from preintervention to postintervention time points. After completing X-CoRe, participants had a significantly greater understanding of active consent (P=.04), confidence in their healthy relationship skills (P=.045), and confidence to intervene as bystanders (P=.01). Although not statistically significant (P>.05), mean scores in attitudes about SH, couple violence, and cyberbullying; perceptions of sexual misconduct as part of military life; and relationship skills self-efficacy with a romantic partner and friend also improved. The findings from this study demonstrate X-CoRe's effectiveness in improving critical determinants of SH and SA, making it a promising intervention for SH and SA prevention. More rigorous research is needed to determine X-CoRe's impact on SH and SA victimization and the long-term impact on associated psychosocial determinants.

The human cost of war: An experimental study of Taiwanese attitudes towards war casualties

This paper investigates public attitudes toward types of war casualties. Through a survey experiment, we examine Taiwanese responses to hypothetical scenarios involving casualties among Taiwan's own military, the US military as allies, the Chinese military as enemy combatants, and mainland Chinese civilians. Our paper reveals three findings: first, there is a stronger aversion among Taiwanese citizens to their own military casualties compared with those of their allies. Second, Taiwanese attitudes toward their own military casualties are more adverse than those incurred by enemy military. Lastly, Taiwanese support for military action diminishes more significantly with Chinese civilian casualties than with Taiwanese military losses.

Strengthening the Psychological Health and Readiness of Military Critical Care Nurses for Disaster and Future Combat Environments.

Critical care nursing is a highly dynamic and demanding field, and critical care nurses play a vital role in the US military health care system. Although many critical care nurses are resilient to myriad occupational exposures, for some nurses the job leads to adverse psychological effects, including compassion fatigue and burnout. This article describes the evidence used to develop a psychoeducation program designed to mitigate burnout among health care professionals, particularly critical care nurses. Implementation considerations (including those in the context of disaster response) and future battlefield are discussed. Ultimately, supporting the psychological health of the US military's critical care nurse force is vital to ensure their well-being, the readiness of our armed forces, and the security of our nation.

Molecular Characterization of Noroviruses Causing Acute Gastroenteritis Outbreaks among US Military Recruits, 2013-2023.

Norovirus is the leading cause of acute gastroenteritis (AGE) worldwide. Norovirus outbreaks at military facilities can cause loss of training and working days and increased healthcare utilization, affecting force readiness. During 2013-2023, we enrolled 2,304 US military recruits from 4 basic training facilities to investigate AGE outbreaks among this population. Among enrollees, we detected norovirus in 433 (18.8%) AGE cases, and norovirus caused 49 AGE outbreaks during our longitudinal study. On average, each norovirus case-patient missed 1.2 training days due to illness, and 6.2% required infusion care. Whole-genome sequencing of selected samples from each outbreak produced full-length genomes (6,989-7,787 bp) for 39 samples. Norovirus GII.4 Sydney was the most (12/39, 30.8%) identified genotype over the study period. Phylogenetic and comparative genomic analyses revealed that several outbreak strains were responsible for causing >1 outbreak, even across different training sites. Our findings can inform infection control practices at military installations and overall norovirus vaccine development.

Molecular Surveillance of Multidrug-Resistant Bacteria among Refugees from Afghanistan in 2 US Military Hospitals during Operation Allies Refuge, 2021.

In 2021, two US military hospitals, Landstuhl Regional Medical Center in Landstuhl, Germany, and Walter Reed National Military Medical Center (WRNMMC) in Bethesda, Maryland, USA, observed a high prevalence of multidrug-resistant bacteria among refugees evacuated from Afghanistan during Operation Allies Refuge. Multidrug-resistant isolates collected from 80 patients carried an array of antimicrobial resistance genes, including carbapenemases (blaNDM-1, blaNDM-5, and blaOXA-23) and 16S methyltransferases (rmtC and rmtF). Considering the rising transmission of antimicrobial resistance and unprecedented population displacement globally, these data are a reminder of the need for robust infection control measures and surveillance.

Low-Titer O-Positive Whole Blood: Lessons From the Battlefield for Civilian Rural Hospitals.

Low-titer O-positive whole blood was used extensively by the military during operations in Iraq and Afghanistan. Studies have consistently shown that this therapy is feasible, safe, and effective in the management of hemorrhagic shock in trauma patients, and it is now the standard of care across the US military Joint Trauma System. The military's success in using low-titer O-positive whole blood has renewed the practice in the civilian setting, with recent research confirming its safety and efficacy. In a few short years, use of this treatment for hemorrhagic shock has expanded to more than 80 US level I and level II trauma centers. However, its use is still relatively rare in the rural hospital setting. This article describes the benefits for patients, staff members, and the overall trauma system of using low-titer O-positive whole blood in rural hospitals.

Azithromycin Resistance Patterns in Escherichia coli and Shigella before and after COVID-19, Kenya.

Escherichia coli and Shigella spp. are leading bacterial causes of acute diarrhea in sub-Saharan Africa and pose risks to global communities, travelers, and the US military. Increasing antimicrobial resistance (AMR) in those and other enteric pathogens creates treatment challenges for clinicians. Inappropriate use of antimicrobial drugs, such as azithromycin for viral respiratory infections, increased during the COVID-19 pandemic. We evaluated AMR trends of 116 E. coli and 109 Shigella spp. isolates obtained from 1,672 pre-COVID-19 (2017-2019) and 1,118 post-COVID-19 (2022-2023) human fecal samples from Kenya. Azithromycin resistance increased significantly from before to after COVID-19, from 6.3% to 40.4% (p = 0.001). Phenotypic AMR profiles from a subset of isolates were compared with genotypic AMR information derived from whole genome sequencing. The most common AMR gene detected was the macrolide mph(A) gene. This study highlights the need for continued AMR surveillance.

Core Mental Health Clinician Capacity and Use Rates in the US Military

Active duty service members have higher mental health stress and cannot choose where to live. It is imperative to understand how geographic access may be associated with their ability to obtain mental health treatment and how the COVID-19 pandemic was associated with these patterns. To identify changes in the prevalence and intensity of mental health care use when service members experienced changes in core mental health clinician (defined to include psychiatrists, psychiatric nurse practitioners, clinical psychologists and social workers, and marriage and family therapists) capacity in their communities and whether patterns changed from before to after the onset of the COVID-19 pandemic. This retrospective cohort study of the active duty population between January 1, 2016, and December 31, 2022, was conducted using individual fixed-effects models to estimate changes in the probability of mental health care visits and visit volume when a person moved across communities with adequate core mental health clinician capacity (≥1 clinician/6000 beneficiaries), shortage areas (<1 clinician/6000 beneficiaries), and areas with 0 clinicians within a 30-minute drive time. All US active duty service members stationed in the continental US, Hawaii, and Alaska were included. Data were analyzed from January through July 2024. The first set of outcomes captured the probability of making at least 1 mental health care visit in a given quarter; the second set of outcomes captured the intensity of visits (ie, the number of visits log transformed). This study included 33 039 840 quarterly observations representing 2 461 911 unique active duty service members from the Army, Navy, Marines, and Air Force (1 959 110 observations among Asian or Pacific Islander [5.9%], 5 309 276 observations among Black [16.1%], 5 287 168 observations among Hispanic [16.0%], and 18 739 827 observations among White [56.7%] individuals; 27 473 563 observations among males [83.2%]; mean [SD] age, 28.20 [7.78] years). When an active duty service member moved from a community with adequate capacity at military treatment facilities to one with 0 clinicians within a 30-minute drive, the probability of a mental health visit to any clinician decreased by 1.13 percentage points (95% CI, -1.21 to -1.05 percentage points; equivalent to a 11.6% relative decrease) and the intensity of total visits was reduced by 7.7% (95% CI, -9.0% to -6.5%). The gap increased from before to after the onset of the COVID-19 pandemic, from 8.5% (equivalent to -0.82 percentage points [95% CI, -0.92 to -0.73 percentage points]) to 16.2% (equivalent to -1.58 percentage points [95% CI, -1.70 to -1.46 percentage points]) in the probability of visiting any clinician type for mental health. In this study, active duty personnel assigned to locations without core military mental health clinicians within a 30-minute drive time were less likely to obtain mental health care and had fewer mental health care visits than those in communities with adequate military mental health capacity even if there was adequate coverage from the civilian sector. The care disparity increased after the onset of the COVID-19 pandemic.

A novel intervention for acute stress reaction: exploring the feasibility of ReSTART among Norwegian soldiers

ABSTRACT Background: Soldiers in combat may experience acute stress reactions (ASRs) in response to trauma. This can disrupt function, increasing both immediate physical danger and the risk for post-trauma mental health sequelae. There are few reported strategies for managing ASRs; however, recent studies suggest a novel peer-based intervention as a promising approach. Objectives: This study assesses the feasibility of ReSTART training, a peer-based course designed to prepare soldiers to manage ASRs. ReSTART builds on programmes established by US and Israeli militaries. The current study evaluates the ReSTART programme in a Norwegian setting, across distinct groups of soldiers, professionals and conscripts. Methods: Participants included professional soldiers deploying to Mali and conscripts with 6 months of service, who completed the ReSTART training course and surveys administered pre- and post-training. These surveys assessed attitudes and programme acceptability. Analyses included 74 soldiers who provided complete survey responses. Results: ReSTART training received high ratings in terms of usefulness, relevance, and importance in managing ASRs. From pre- to post-training, respondents had significant increases in positive attitudes towards ASR management and confidence in handling ASRs personally, and at the unit level; decreases in stigma-related attitudes associated with ASRs; and increased perception of leadership emphasizing ASR management. Conclusions: ReSTART training shows potential as an effective tool when preparing soldiers to manage ASRs in high-risk environments, enhancing military units’ capacity to support each other and effectively respond to stress-induced functional disruptions. This study adds evidence supporting the utility of peer-based ASR management in operational settings and highlights the need for broader implementation and systematic evaluation.

Toiling for oil: Daqing, real utopias and the production of livelihood in communist China

This dialogical interrogation of Hou Li’s important history of Daqing examines the contradictions of structure and agency in the building of communist China’s first oil city. Three provocations are raised. Two relate to ecology: the first on the ecological dimension of extractivism, which requires careful consideration in light of the current status of CO2 emissions per capita, with China accounting for about half the emissions of fossil fuel exporters like Australia; the second on how extractivism and decarbonization can be considered in light of recent claims that the US military was the world’s largest consumer of hydrocarbons in 2019. The third relates to the ambiguity of the term “capital” in economic discourse, which invariably finds its way into cognate scholarly disciplines, such as historical inquiry and urban planning.

Immediate Breast Reconstruction After Mastectomy for Cancer Among US Military Health System Beneficiaries.

In the Military Health System (MHS), women with breast cancer may undergo surgical treatment in military hospitals (direct care) or in the civilian setting via the insurance benefit (private sector care). We conducted this study to determine immediate breast reconstruction rates among women undergoing mastectomy for cancer in the MHS by setting of care. Using the linked Department of Defense's Central Cancer Registry and MHS Data Repository, the Department of Defense's medical claims database, we identified adult women who underwent mastectomy for breast cancer from 1998 to 2014. Patients were then subgrouped by setting of care (direct vs private sector care). The primary outcome was the rate and type of immediate breast reconstruction. Regression models were constructed to determine factors associated with receipt of immediate breast reconstruction. The final sample included 3251 women who underwent mastectomy for cancer in the direct (67.0%) or private sector care (32.6%) settings. The overall rate of immediate breast reconstruction was 29.9% with an upward trend noted throughout the study (P < 0.001). Overall, implant-based reconstruction (81.4%) was more common than tissue-based reconstruction (18.6%). Compared with direct care, the immediate breast reconstruction rate was significantly higher in the private sector care setting (49.3% vs 20.5%, P < 0.001) despite accounting for differences in clinical characteristics (adjusted odds ratio = 4.51, 95% confidence interval [3.72-5.46]). Immediate breast reconstruction in the direct care setting lags that in the civilian community during the study time period. Further research is needed to ascertain current immediate reconstruction rates and understand factors contributing to any differences in rates between care settings.
