RESUMEN

In vitro and vivo studies indicate that oxidative stress contributes to bone loss. Fluorescent oxidation products (FlOPs) are novel biomarkers of oxidative stress; they reflect global oxidative damage of lipids, proteins, carbohydrates, and DNA. However, whether FlOPs are associated with bone mineral density (BMD) is still unclear. In the present study, we examined the association between FlOPs and BMD among male veterans. This cross-sectional study was conducted among participants recruited from the Department of Medical Examination, The Second Hospital of Jilin University in Jilin, China. We identified male veterans who were at least 50 y old between June and October of 2019. Plasma FlOPs were measured with a fluorescent microplate reader (excitation/emission wavelength: 320/420 nm). BMD were measured by dual-energy X-ray absorptiometry (DXA). The association between FlOPs and BMD was tested by multivariable linear regression models. A total of 164 male veterans were enrolled in the study, the average age was 56.6 y. After adjusting for covariates, veterans who had FlOP levels in the highest tertile had a statistically significant lower femoral neck (ß = -0.044; p = 0.007) and total hip BMD (ß = -0.045; p = 0.020) as compared to those with FlOP levels in the lowest tertile. Similar results were found when FlOPs were treated as a continuous variable (per 1-SD increase, ß = -0.014 and p = 0.033 for femoral neck BMD; ß = -0.016 and p = 0.047 for total hip BMD). Higher FlOP levels were associated with lower BMD among male veterans.

RESUMEN

In the 1970s, following the Vietnam Conflict, the U.S. military transitioned to an All-Volunteer Force (AVF). In the 1980's military benefits increased and a zero-tolerance policy for illicit drugs was instituted. Changes in characteristics of veterans deserve study. National survey data from 2012 to 2013 compare vetderan-non-veteran differences in three age cohorts: the Vietnam cohort; the AVF (Post-Vietnam) cohort; and volunteers under the no tolerance policy (Post-Post-Vietnam). Comparisons addressed socio-demographic, behavioral, and substance use and psychiatric diagnoses. Multivariate interaction analyses between veteran status and age cohorts were used to identify significant veteran-non-veteran differences between the first and second, and second and third cohorts. Significant interactions showed that veteran-non-veteran comparisons for the Post-Vietnam cohort as compared to Vietnam cohort reveal later veterans to be relatively more likely to be black, disabled, with lower incomes, less health insurance, more homelessness, incarceration, and suicide attempts with greater substance use diagnosis. In contrast interactions show veteran-non-veteran comparisons for the Post-Post-Vietnam cohort as compared to Post-Vietnam cohort were less likely to be black, more likely to be married, retired, with incomes over $40,000, more education and private health insurance. They were less likely to have been homeless, incarcerated or to have made suicide attempts. The veteran cohort serving in the first years of the AVF showed significant socio-economic and behavioral disadvantage (e.g homelessness) compared to their predecessors while their successors, under no tolerance drug policy, showed reversal of these trends. Military recruitment and disciplinary policies significantly affect veteran economic and health status.

RESUMEN

Posttraumatic stress disorder (PTSD) is a trauma-induced disorder characterized with impaired cognitive function. BDNF modulates cognition and is involved in neuroprotection and neurocognitive processing. The BDNF Val66Met polymorphism was found to influence cognitive functions. In PTSD, carriers of the BDNF GG genotype had better spatial processing of navigation performance, and lower hyperarousal and startle reaction than A allele carriers. The hypothesis was that veterans with PTSD, carriers of the BDNF Val66Met A allele, will show reduced cognitive skills. The study included 315 male Caucasian combat veterans, with (N = 199) or without (N = 116) current and chronic PTSD. Cognition was assessed using the Rey-Osterrieth Complex Figure (ROCF) test that determines visual-spatial perception and short and long-term visual memory function. The results revealed that cognitive decline measured with ROCF test was associated with PTSD. Presence of the BDNF Val66Met GG genotype in veterans with PTSD, but not in veterans without PTSD, showed protective association with visual short-term memory and visual object manipulation after few seconds (executive function), assessed with the ROCF immediate recall test, compared to the A carriers with PTSD. In conclusion, this was the first study to confirm the association between BDNF Val66Met and memory and attention performed with ROCF in male veterans with PTSD. The results corroborated that the BDNF Val66Met A allele, compared to GG genotype, is associated with poorer short-term visual memory and attention linked with executive functions, in veterans with PTSD.

RESUMEN

Objective: To examine the relationships between resiliency, sociodemographic factors, and allostatic load among male Veterans. Design/Study Participants: Cross-sectional study with minority (African American or Hispanic) and non-minority (White) male Veterans undergoing prostate biopsy. Setting: Veterans Affairs Medical Center located in Charleston, SC. Main Outcome Measures: Self-reported resilience measured using the two item sub-scale from the Connor-Davidson Resiliency Scale and allostatic load determined from biomarkers measured in blood. Results: In this small sample, bounce-back resilience and allostatic load level had a significant negative correlation, while adaptation resilience and allostatic load were slightly correlated, but the association was not statistically significant. Sixty-six percent of participants reported that they were able to adapt and 40% reported they were able to bounce back. Higher income and lower PSA level were significantly correlated with greater adaptation resilience. Minority men were significantly more likely than non-minority men to report that they are able to bounce back. Married men were also significantly more likely than unmarried men to report that they were able to bounce back. Conclusion: It may be important to target resiliency training programs to Veterans based on their social determinants and to examine the effects of these programs on allostatic load.

RESUMEN

INTRODUCTION: Among health problems in the Veteran population, the most common is posttraumatic stress disorder (PTSD) and its effect on the quality of life. Prolonged Exposure therapy, based on emotional processing theory, is a first-line treatment for reducing PTSD symptom severity when delivered in an individual format, and its efficacy is well established. The primary objective of this study is to establish the efficacy of prolonged exposure delivered in a small 3-person group modality. Quality of life should improve with decreases in PTSD symptoms such as sleep disturbance, irritability, and hypervigilance. Stigma is associated with hesitation in seeking treatment and treatment dropout. A secondary objective is to measure the effect of group treatment on reducing the stigma surrounding PTSD. METHODS/DESIGN: This study is a randomized controlled trial testing the efficacy of Group Prolonged Exposure (PE) for reducing PTSD symptom severity and improving quality of life in male Afghanistan and Iraq Veterans. All participants are randomly assigned to receive Group PE or Group Present-Centered Therapy (PCT) for 10-weekly, 90-min sessions. Group PE focuses on processing trauma memories, while the goal of Group PCT is improved psychosocial functioning through management of current stressors. The primary outcome is improvement in CAPS-5 PTSD symptom severity scores and quality of life measures (WHO-QOL and SF-36) from pre-treatment to post-treatment, 3-months post-treatment, and 6-months post-treatment. A secondary outcome is reductions in perceived self-stigma of mental illness based on the Stigma Scale at baseline and follow-up points. This study is designed to expand access to this first-line treatment for PTSD by delivering PE in a small group modality while conforming to the individual PE protocol, with group treatment reducing perceived stigma of mental illness.

RESUMEN

Impaired body satisfaction is commonly reported among cancer patients. This study prospectively evaluated body image disturbance among male military veterans with head and neck or colorectal cancer. Patients ( N = 109) completed measures at three points post-diagnosis. Results showed about one-third of participants reporting body-related concerns. Endorsement did not change significantly during the study period. Predictors of worse body satisfaction included younger age, lower education, less social support, and weight loss. Results indicate a substantial minority of men with cancer endorsing body image disturbance, and highlight psychosocial circumstances and weight change as key considerations.

RESUMEN

Core features of posttraumatic stress disorder (PTSD) are cognitive disturbances. Enzyme catechol-O-methyltransferase (COMT) degrades dopamine primarily in prefrontal cortex. Its functional polymorphism, COMT Val158/108Met, affects COMT activity and dopamine availability and is associated with disturbances in cognition. The hypothesis was that PTSD subjects will have worse working memory than healthy controls and that the carriers of the COMT Met allele will show better cognitive performance compared to Val/Val carriers in PTSD and controls subjects. The aim of this study was to assess the differences in cognitive functioning between PTSD and control subjects and to evaluate the association between COMT Val158/108Met polymorphism and cognitive function determined using the Rey-Osterrieth complex figure (ROCF) copy, immediate and delayed test. The study included 323 male Caucasian participants of Croatian origin: 205 male combat veterans with PTSD and 118 control subjects. A significant association between the COMT Val158/108Met and the ROCF immediate and delayed scores in veterans with PTSD was found. We confirmed, on ethnically homogenous groups of veterans with matched combat experience, that controls had higher ROCF immediate and delayed test scores than veterans with PTSD. In PTSD subjects, the Met carriers of the COMT Val158/108Met performed better (i.e. had higher ROCF scores) than Val/Val homozygotes on both ROCF immediate recall and delayed recall test. Our results provide the first evidence that the presence of one or two Met alleles of the COMT Val158/108Met might act as a protective variant in working memory tasks in combat exposed veterans with PTSD.

RESUMEN

BACKGROUND: The children of male veterans with combat-related posttraumatic stress disorder (PTSD) are at particularly high risk of emotional and behavioral problems. However, no studies have examined non-suicidal self-injury (NSSI) in this population of youth. AIMS: To determine the prevalence and psychosocial correlates of lifetime NSSI in a sample of psychiatric outpatient adolescent offspring of Croatian PTSD male veterans. METHOD: Consecutive outpatient adolescent offspring of Croatian male PTSD veterans, aged 12 to 18 years, were assessed on the Deliberate Self Harm Inventory, the Youth Self-Report, the Family Assessment Device, the Parental Bonding Instrument and the Demographics Questionnaire. RESULTS: Of the whole sample, 52.7% of adolescents reported NSSI at least once during their lifetime. Lifetime NSSI was significantly associated with internalizing symptoms (adjusted odds ratio (OR) = 2.14; 95% confidence interval (CI): 1.04-4.42, p = .040), poor family functioning (adjusted OR = 6.54; 95% CI: 2.02-21.22, p = .002), lower maternal and paternal care (adjusted OR = 0.47; 95% CI: 0.40-0.56, p = .000 and adjusted OR = 0.82; 95% CI: 0.73-0.91, p = .000, respectively) and higher paternal control (adjusted OR = 1.84; 95% CI: 1.59-2.14, p = .000) in multivariate analysis. No association was found between lifetime NSSI and any of the socio-demographic variables. CONCLUSION: NSSI is a significant clinical problem in outpatient adolescent offspring of PTSD male veterans, which may be influenced by clinical and family factors. Interventions aimed at reducing internalizing symptoms and improving family functioning and parental behaviors are needed in the treatment of adolescent offspring of male PTSD veterans engaging in NSSI.

RESUMEN

Veterans comprise 10% of the population, and suicide among Veterans has garnered national media and policy attention. Existing research suggests that intimate partner violence (IPV) is a risk factor for suicidal behaviors among some high-risk populations. This report offers a new perspective: the intersection between Veterans' suicidal thoughts and IPV, both victimization and perpetration. The data were obtained from a northeast telephone survey of Veterans (n = 296) using Veterans Health Administration services and yielded a 27% participation rate. Findings suggest male Veterans who are IPV involved have increased odds of suicidal thoughts and behaviors.

RESUMEN

OBJECTIVE: The purpose of this study was to use group reminiscence therapy (GRT) as a nursing intervention to evaluate the post-test, 3-month and 6-month effects on depressive symptoms for institutionalised male veterans after a 4-week intervention. METHODS: A quasi-experimental design and purposive sampling was conducted at a veteran's nursing home in Northern Taiwan. A total of 21 male veterans were studied to measure the effect of GRT. Eleven participants were in the experimental group and 10 in the control group. The experimental group activity was held twice weekly for 4 weeks. The Taiwan Geriatric Depression Scale was used to assess depressive symptoms and geriatric depression among male veterans. The generalised estimating equation was used for data analysis. RESULTS: The male veterans in this study had a mean age of 82 years (SD = 5.8); 47.62% were between 70 and 79 years old, 61.90% were illiterate and 90.48% were without a partner. After 4 weeks of GRT, the experimental group significantly improved their depressive symptoms and geriatric depression in the post-test, 3-month and 6-month follow-up data compared with the control group. These activities can reduce their depressive symptoms following the intervention. CONCLUSION: A 4-week, eight-session GRT can effectively reduce depressive symptoms among institutionalised male veterans for a 6-month period.
