[PMID: 36127194 DOI: 10.1016/j.amepre.2022.07.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2022] [Revised: 06/29/2022] [Accepted: 07/14/2022] [Indexed: 11/26/2022]
Abstract
INTRODUCTION Previous studies have identified combat exposure and combat traumatic experience as problematic drinking risk factors. Increasing evidence suggests that opioid use increases the risk of alcohol use disorder. This study investigated the association between opioid prescription use after injury and (1) alcohol use disorder and (2) severity of alcohol use disorder among deployed military servicemembers. METHODS Deidentified health records data of 9,029 deployed servicemembers from a retrospective cohort study were analyzed. Data were randomly selected from the Department of Defense Trauma Registry and included servicemembers with combat injuries during deployment in Iraq or Afghanistan (2002-2016). Pharmacy records and International Classification of Diseases, Ninth and Tenth Revision diagnosis codes were used. Three groups were identified (no opioid prescription use, nonpersistent opioid prescription use, and persistent opioid prescription use) and were compared on the basis of alcohol use disorder risk using Cox proportional hazard models. Data analyses were performed in 2021. RESULTS Of the 9,029 servicemembers with combat injury, 2,262 developed alcohol use disorder (1,322 developed severe alcohol use disorder). Compared with no opioid prescription use, increased alcohol use disorder risk was associated with persistent opioid prescription use, with a hazard ratio of 1.13 (95% CI=1.02, 1.26). After covariate adjustment, increased risk remained statistically significant (hazards ratio=1.24; 95% CI=1.10, 1.39). There was no significant difference in alcohol use disorder risk between no opioid prescription use and nonpersistent opioid prescription use. The risk of severe alcohol use disorder did not vary by opioid use among servicemembers with alcohol use disorder diagnosis. CONCLUSIONS The findings of the study suggest that the incidence of alcohol use disorder was higher among injured servicemembers with persistent opioid prescription use than among those without opioid use. If replicated in prospective studies, the findings highlight the need for clinicians to consider the current and history of alcohol use of patients in initiating treatment involving opioids.

Abstract
The prevalence of co-occurring posttraumatic stress disorder (PTSD) and substance use disorder (SUD) remains exceptionally high among returning veterans, with numerous studies linking PTSD, but not specific PTSD symptoms, to future SUD risk. Further explication of PTSD symptom effects on future SUD risk will likely promote intervention development and refinement while offsetting SUD risk. Accordingly, In this study we explored the prospective associations between PTSD symptom clusters, symptoms, and future SUD risk and use of specific drug classes. Returning veterans (N = 1,295; Mage = 42.3, SD = 9.89; 51% female; 66.8% White) completed structured diagnostic interviews to assess PTSD symptoms and self-report measures of substance use 14-36 months later (M = 24.59, SD = 2.97). Hyperarousal and reckless/self-destructive symptoms specifically predicted future high-risk drug use and binge drinking behavior, and avoidance of internal stimuli (i.e., of trauma memories, thoughts, and feelings) differentiated individuals classified as high-risk for alcohol use based on their AUDIT total score. Further, negative alterations in cognition and mood predicted future opioid (i.e., nightmares) and stimulant use (i.e., flashbacks), whereas concentration difficulties were inversely associated with future binge drinking. This longitudinal study identified prospective and enduring associations between specific PTSD symptom clusters, symptoms, and future high-risk substance use patterns among returning veterans. Accordingly, careful assessment of specific PTSD criteria and differential motivations for substance use is warranted, along with tailored interventions to offset risk for opioid, stimulant, and alcohol use among returning veterans.

Abstract
Bayesian networks are powerful statistical models to study the probabilistic relationships among sets of random variables with significant applications in disease modeling and prediction. Here, we propose a continuous time Bayesian network with conditional dependencies represented as regularized Poisson regressions to model the impact of exogenous variables on the conditional intensities of the network. We also propose an adaptive group regularization method with an intuitive early stopping feature based on Gaussian mixture model clustering for efficient learning of the structure and parameters of the proposed network. Using a dataset of patients with multiple chronic conditions extracted from electronic health records of the Department of Veterans Affairs, we compare the performance of the proposed network with some of the existing methods in the literature for both short-term (one-year ahead) and long-term (multi-year ahead) predictions. The proposed model provides a sparse intuitive representation of the complex functional relationships between multiple chronic conditions. It also provides the capability of analyzing multiple disease trajectories over time, given any combination of preexisting conditions.

Abstract
OBJECTIVE To investigate associations of lifetime traumatic brain injury (LT-TBI) prior to an index deployment, and/or deployment-acquired TBI (DA-TBI), with postdeployment binge and heavy drinking. SETTING Soldiers from 3 Brigade Combat Teams deployed to Afghanistan in 2012. PARTICIPANTS A total of 4645 soldiers who participated in the Army STARRS Pre/Post Deployment Study and completed 4 assessments: T0 (1-2 months predeployment), T1 (upon return to United States), T2 (3 months postdeployment), and T3 (9 months postdeployment). DESIGN Prospective, longitudinal study controlling for baseline binge drinking. MAIN MEASURES Self-reported past month binge drinking (5+ alcoholic beverages on the same day) and past month heavy drinking (binge drinking at least weekly) at T2 and T3. RESULTS In total, 34.3% screened positive for LT-TBI, and 19.2% screened positive for DA-TBI. At T2 only, LT-TBI, but not DA-TBI, was associated with increased odds of binge drinking (adjusted odds ratio [AOR] = 1.39, 95% confidence interval [CI]: 1.20-1.60, P < .001) and heavy drinking (AOR = 1.28, 95% CI: 1.09-1.49, P = .007). Among the subgroup with LT-TBI, also having DA-TBI was associated with increased risk of heavy drinking at T3 (AOR = 1.42, 95% CI: 1.03-1.95, P = .047). CONCLUSION Routine screening for LT-TBI may help target efforts to prevent alcohol misuse among military members.

Abstract
PURPOSE Drinking is common among young adult veterans. Previous research has established that veterans' drinking is more strongly associated with veteran versus civilian drinking norms. The present research extends these findings by examining the influence of self-identification both with other veterans and with civilians as moderators of the association between perceived norms and drinking. METHODS Veterans aged 18-34 (N = 1015; 88.7% male; M = 28.23, SD = 3.44) were recruited via Facebook to participate. Measures included same-gender veterans/same-gender civilians self-identification, same-gender veterans/same gender-civilians perceived drinking norms, and own drinking. RESULTS Pairwise comparisons revealed both male and female veterans identified more with other veterans than civilians and perceived drinking to be more prevalent among other veterans than civilians. However, males overestimated male veteran drinking norms to a greater degree than male civilian norms whereas the opposite was true for females. Negative binomial analysis examining a three-way interaction between veteran identification, civilian identification, and civilian norms revealed civilian drinking norms were positively associated with drinking, particularly for veterans who strongly identified with both veterans and civilians. Conversely, civilian drinking norms were also found to be negatively associated with drinking, particularly for those who did not identify strongly with civilians but identified strongly with veterans. IMPLICATIONS This study represented a preliminary step for understanding how identity plays a role in terms of veterans' drinking. Given that veterans drank at differing levels of identification, it may be important to consider identities that are most salient when designing interventions targeting individual veterans.

Abstract
Recently, there has been a growing interest in the use of cannabis after traumatic brain injury (TBI); however, little is known about the long-term effects of cannabis on milder injuries and post-concussive symptoms. Further, substance use often increases post-TBI and, thus, individuals who chronically use cannabis may unknowingly be exceeding safe or therapeutic doses. The current cross-sectional study explores the prevalence of cannabis use among university students with and without a history of concussion and examines the relationship between concussion and post-concussive symptoms as a function of cannabis use. Eighty-four undergraduates (n = 51 without a prior concussion; n = 33 with a prior concussion) completed a series of questionnaires, capturing their head injury history, current and past substance use, and post-concussive symptomatology. Results indicated that those with a history of concussion were more likely to use cannabis and had higher cannabis use severity scores compared to those without a previous concussion. Further, among cannabis users only, concussion severity demonstrated a significant positive association with post-concussive symptom (e.g., headaches, memory problems) severity (i.e., frequency, intensity, duration). Taken together, the long-term use of cannabis may be detrimental to individuals with a history of concussion, exacerbating, rather than mitigating, post-concussive symptoms.

Abstract
Posttraumatic stress disorder (PTSD) is associated with higher levels of alcohol use among returning veterans. Persistent PTSD symptoms can predict alcohol use over the span of hours, days, weeks, and months; however, knowledge of the strength of these associations beyond 1 year remains limited. In this study, we examined the 6-year course of co-occurring PTSD and alcohol use to explicate the directional and possible enduring effects of PTSD on alcohol use severity over time. Our study included 1,649 returning veterans (M age = 37.49; SD = 9.88) who completed 4 waves of data collection between 2010 and 2016. We used parallel process modeling to evaluate temporal associations between PTSD symptoms and alcohol use severity across 4 (T1-T4) waves of data collection. PTSD and alcohol use both decreased significantly between T1 and T4 and in tandem with one another. That is, decreases in one were associated with decreases in the other. Further, individuals with higher levels of PTSD symptom severity at T1 reported accelerated rates of change regarding PTSD symptoms and alcohol use over time. Conversely, baseline alcohol use severity did not predict the rate of change in PTSD symptom severity. Our findings provide evidence of a prospective association between PTSD symptoms and alcohol use and highlight the potential for reciprocal associations between them over the span of years. Importantly, our demonstration of the natural course of co-occurring PTSD symptoms and alcohol use suggests further trauma-focused and combined intervention strategies are needed to disrupt this enduring and reciprocal pattern among returning veterans.

Abstract
BACKGROUND Military personnel engage in alcohol-related behaviors for a variety of reasons, some of which may be socially-motivated. Although civilian-based research has established that peers' drinking behaviors are correlated with individuals' own drinking behaviors, military work has not yet examined the influence of social network characteristics on soldier drinking behaviors. This study describes characteristics of soldiers' social networks in association with soldier alcohol use problems. METHODS This study includes data on 353 U.S. Reserve and National Guard (R/NG) soldiers and their 2154 past-year social ties. Descriptive analyses examined social tie characteristics (e.g., military affiliation, substance misuse, and drinking influence). Negative binomial regression models examined relationships between social network characteristics and soldier alcohol use problems. RESULTS On average, 14% of a R/NG soldier's social network was comprised of military-affiliated ties. Further, an average of 14% of ties in a soldier's network were considered drinking buddies, and 8% of ties were heavy-drinkers. More drinking buddies and heavy-drinking ties in a soldier's social network and greater average number of past-month days drinking with ties were associated with increases in soldier alcohol problems. For deployed soldiers, larger military-affiliated social networks were protective against alcohol problems. CONCLUSIONS Drinking-related social network characteristics are associated with increased alcohol problems among soldiers, while military-affiliated ties are protective specifically for deployed soldiers. Interventions to reduce alcohol use problems may focus on enhancing social connections between R/NG soldiers and providing opportunities to connect deployed R/NG soldiers with one another during and after reintegration.

Abstract
Background: Post-traumatic stress disorder (PTSD) has been identified by past research as a risk factor for substance use. Further, past research has indicated that individuals with PTSD may demonstrate an increased sensitivity to strain. Despite this, no study has examined the relevance of these processes for understanding binge drinking behaviors from a developmental perspective. Purpose/Objectives: Understand the relevance of PTSD-linked strain sensitivity for predicting binge drinking in adolescence and adulthood. Methods: This study utilizes data from the Pathways to Desistance study, comprising the responses of 1354 juvenile offenders across seven years following an adjudication. A series of ordinal logistic regression models estimated these effects in adolescence and early adulthood. Results: Results indicate that adolescent PTSD interacted with witnessed violence to produce lower frequency binge drinking. This effect was non-significant in early adulthood. Conclusions/Importance: These findings indicate that adolescent PTSD-sufferers demonstrate diminished sensitivity to witnessed violence. This may have to do with adolescence social processes.

Abstract
BACKGROUND Research suggests bidirectional associations between symptoms of posttraumatic stress disorder (PTSD) and sleep disturbance, both of which have been associated with alcohol problems. However, few studies have examined the interplay of these conditions in predicting alcohol problems over time. This study tested 2 competing models: (i) sleep disturbance as a mediator of the association between intrusive thoughts about trauma and alcohol problems and (ii) intrusion symptoms as the mediator of the sleep/alcohol problem association. METHODS Veterans (N = 325, 93% male, 81% White) completed assessments at baseline, 6 months, and 12 months as part of a larger observational study. Zero-inflated-negative binomial models were used to examine indirect effects of baseline predictors on (i) yes/no likelihood and (ii) number of 12-month alcohol problems through 6-month mediators. Models controlled for past-year cannabis use and drinks consumed per week at baseline. RESULTS The only significant predictor of alcohol problem likelihood was baseline drinking quantity. Baseline PTSD intrusions had a direct effect on number of alcohol problems at 12 months, with no indirect (mediated) effect through 6-month sleep disturbance. In the competing model, baseline sleep disturbance had a marginally significant direct effect on 12-month alcohol problems, with a significant indirect effect through 6-month PTSD intrusions. CONCLUSIONS PTSD intrusions are associated with more alcohol problems and help explain the long-term association between sleep and alcohol problems among veterans. Because sleep disturbances are associated with more intrusive thoughts about trauma, we recommend that treatments targeting sleep in the context of PTSD and alcohol use include a cognitive component.

Abstract
BACKGROUND Pain and its consequences remain of concern, particularly in high-risk occupations such as the military. Alcohol is a legal and accessible means of self-medication, and risky alcohol use is associated with potentially serious consequences. This exploratory analysis aimed to better understand the association of selected pain diagnoses with risky alcohol use among soldiers returning from deployment. Methods: Analysis of data from active duty soldiers returning from Afghanistan or Iraq deployments in fiscal years 2008-2011 who completed Department of Defense health questionnaires after deployment (n = 267,100). Each questionnaire included self-reported alcohol consumption and items yielding AUDIT-C screening scores. Military Health System data were used to identify diagnoses of pain-related conditions. Results: About 70% of soldiers had none of the selected pain diagnoses either pre- or post-deployment. 10% had incident pain diagnoses (only post-deployment), 7% had persistent pain diagnoses (both pre- and post-deployment), and 13% had remitted pain diagnoses (only pre-deployment). On the AUDIT-C, 39% screened positive for at-risk drinking and 6% were likely to have severe alcohol problems. Half of the respondents reported any binge drinking; 20% at least monthly binge drinking. Logistic regression analyses found reduced odds of risky alcohol use post-deployment in association with incident and persistent pain diagnoses, compared to no pain diagnoses pre- or post-deployment. Conclusions: Pain diagnoses, binge drinking, and risky alcohol use were prevalent among this sample of Army soldiers. An inverse relationship was found between pain diagnosis (incident, persistent) and risky alcohol use post-deployment. Attention should continue to be paid to risky alcohol use in this population, yet these exploratory findings do not suggest that soldiers with the pain diagnoses used in this study are at greater risk. Combat exposure, traumatic brain injury, and psychological health were more important predictors, and should continue to warrant enhanced alcohol screening.

Abstract
Converging lines of evidence point to a significant role of neuroinflammation in a host of psychiatric conditions, including alcohol use disorder, TBI, and PTSD. A complex interaction of both peripheral and central signaling underlies processes involved in neuroinflammation. Calcineurin is a molecule that sits at the nexus of these processes and has been clearly linked to a number of psychiatric disorders including alcohol use disorder (AUD). Like its role in regulating peripheral immune cells, calcineurin (CN) plays an integral role in processes regulating neuroimmune function and neuroinflammatory processes. Targeting CN or elements of its signaling pathways at critical points may aid in the functional recovery from neuroinflammatory related disorders. In this review we will highlight the role of neuroinflammation and calcineurin signaling in AUD, TBI and stress-induced disorders and discuss recent findings demonstrating a therapeutic effect of immunosuppressant-induced calcineurin inhibition in a pre-clinical model of binge alcohol drinking.

Abstract
Although many researchers have demonstrated an increase in alcohol use following traumatic brain injury (TBI), there is also a body of research indicating that alcohol misuse predisposes one to injury and precedes TBI. Accordingly, various mechanisms have been proposed (e.g., self-medication, dampened levels of arousal, dopaminergic dysfunction, etc.) and variable results have emerged. This paper reviews the empirical evidence, for and against, TBI as a risk factor for alcohol misuse. In particular, this paper focuses on the brain-behavior relationships involved and examines the roles of physiological underarousal and dopaminergic dysfunction in the development of alcohol misuse after injury. Alcohol misuse impedes community reintegration among TBI survivors and creates additional rehabilitative challenges. Thus, in order to inform and improve treatment outcomes among this vulnerable population, a deeper understanding of the neural mechanisms implicated is needed.

Mining patterns of comorbidity evolution in patients with multiple chronic conditions using unsupervised multi-level temporal Bayesian network. PLoS One 2018; 13:e0199768.

Abstract
Over the past few decades, the rise of multiple chronic conditions has become a major concern for clinicians. However, it is still not known precisely how multiple chronic conditions emerge among patients. We propose an unsupervised multi-level temporal Bayesian network to provide a compact representation of the relationship among emergence of multiple chronic conditions and patient level risk factors over time. To improve the efficiency of the learning process, we use an extension of maximum weight spanning tree algorithm and greedy search algorithm to study the structure of the proposed network in three stages, starting with learning the inter-relationship of comorbidities within each year, followed by learning the intra-relationship of comorbidity emergence between consecutive years, and finally learning the hierarchical relationship of comorbidities and patient level risk factors. We also use a longest path algorithm to identify the most likely sequence of comorbidities emerging from and/or leading to specific chronic conditions. Using a de-identified dataset of more than 250,000 patients receiving care from the U.S. Department of Veterans Affairs for a period of five years, we compare the performance of the proposed unsupervised Bayesian network in comparison with those of Bayesian networks developed based on supervised and semi-supervised learning approaches, as well as multivariate probit regression, multinomial logistic regression, and latent regression Markov mixture clustering focusing on traumatic brain injury (TBI), post-traumatic stress disorder (PTSD), depression (Depr), substance abuse (SuAb), and back pain (BaPa). Our findings show that the unsupervised approach has noticeably accurate predictive performance that is comparable to the best performing semi-supervised and the second-best performing supervised approaches. These findings also revealed that the unsupervised approach has improved performance over multivariate probit regression, multinomial logistic regression, and latent regression Markov mixture clustering.

Traumatic Brain Injury and Post-Deployment Binge Drinking among Male and Female Army Active Duty Service Members Returning from Operation Enduring Freedom/Operation Iraqi Freedom.

Abstract
This study examines whether the relationship between traumatic brain injury (TBI) and post-deployment binge drinking is independent of screening positive for mental health problems among male and female service members. Data are from the Substance Use and Psychological Injury Combat Study of Army members returning from deployment to Afghanistan or Iraq in fiscal years 2008-2011. The sample consists of 240,694 male and 26,406 female active duty members who completed initial and follow-up questionnaires. The initial questionnaire, completed at the end of deployment, included screens for TBI and mental health problems (post-traumatic stress disorder, depression, harmful thoughts). The dependent variable, frequent binge drinking (six or more drinks on one occasion, at least monthly), was assessed on the follow-up questionnaire on average 3-9 months post-deployment. More than 21% of males and 7% of females reported frequent binge drinking. Male members were more likely to screen positive for TBI, compared with females (7.5% vs. 4.4%). Females with both TBI and mental health positive screens had more than double the risk of frequent binge drinking, compared with those without either problem (15.8% vs. 6.6%), and males with both problems had almost double the risk, compared with males with neither problem (33.6% vs. 19.7%). In multivariable logistic regression models, having a TBI and a comorbid positive mental health screen was associated with increased odds of frequent binge drinking among both males and females (adjusted odds ratio [AOR] = 1.59, CI: 1.50-1.69, and AOR = 2.11, CI: 1.57-2.83, respectively), compared with those with neither condition. More research is needed on the interaction of gender and binge drinking, especially when TBI and mental health problems co-exist.
