RESUMO

Alcohol addiction is a chronic relapsing disorder that presents a substantial public health problem, and is frequently co-morbid with posttraumatic stress disorder (PTSD). Craving for alcohol is a predictor of relapse to alcohol use, and is triggered by cues associated with alcohol and trauma. Identification of reliable and valid laboratory methods for craving induction is an important objective for alcoholism and PTSD research. The present study compares two methods for induction of craving via stress and alcohol cues in individuals with co-morbid alcohol dependence (AD) and PTSD: the combined Trier social stress test and cue reactivity paradigm (Trier/CR), and a guided imagery (Scripts) paradigm. Outcomes include self-reported measures of craving, stress and anxiety as well as endocrine measures. Subjects were 52 individuals diagnosed with co-morbid AD and PTSD seeking treatment at the National Institute on Alcohol Abuse and Alcoholism inpatient research facility. They participated in a 4-week inpatient study of the efficacy of a neurokinin 1 antagonist to treat co-morbid AD and PTSD, and which included the two challenge procedures. Both the Trier/CR and Scripts induced craving for alcohol, as well as elevated levels of subjective distress and anxiety. The Trier/CR yielded significant increases in adrenocorticotropic hormone and cortisol, while the Scripts did not. Both paradigms are effective laboratory means of inducing craving for alcohol. Further research is warranted to better understand the mechanisms behind craving induced by stress versus alcohol cues, as well as to understand the impact of co-morbid PTSD and AD on craving.

RESUMO

Background: The Department of Veterans Affairs (VA) seeks to transform its health care delivery from disease-centered, episodic care to a holistic and patient-centered model known as the Whole Health System (WHS) of care. Employee engagement and buy-in are crucial to this cultural transformation. The VA aspires to provide employees with opportunities to experience whole health in their personal and professional lives through a national Employee Whole Health (EWH) program. Although there are national recommendations, different local facilities may have unique strategies and challenges as they implement this program. Objective: This study aimed to conduct a program evaluation of EWH at three different VA facilities across the United States in order to identify facilitators and barriers to the implementation of EWH. Methods: The team used the RE-AIM framework to develop an interview guide to assess various domains of implementation. Quantitative data on whole health offerings at each site were gauged using a national employee education platform. Standardized employee-related metrics at each site were assessed using the annual, national VA employee survey. Results: EWH has had variable implementation at the three sites. Sites noted main facilitators as employee interest as well as available skills and expertise for delivering complementary and integrative care to employees. Limited staffing for EWH and a lack of dedicated employee time were cited as barriers. The infrastructure to perform local program evaluations to demonstrate effectiveness and impact were missing. Conclusion: Employee engagement in whole health activities has the potential to support the VA's mission to transform its health care delivery model. Currently, the use of EWH and its potential impact are difficult to discern based on available information. Local sites need guidance to conduct program evaluations and find creative solutions to enhance employee participation. A robust measurement system to demonstrate effectiveness is paramount to ensure the success of this initiative.

RESUMO

Background: Roughly half of patients with alcohol use disorder prefer non-abstinence based approaches to treatment. However, only individuals who can limit their alcohol use after low-risk consumption are most likely to benefit from these approaches. This pilot study developed a laboratory-based intravenous alcohol self-administration paradigm to determine the characteristics of individuals who could successfully resist consuming alcohol after an initial exposure. Methods: Seventeen non-treatment seeking heavy drinkers completed two versions of an intravenous alcohol self-administration paradigm designed to assess impaired control over alcohol use. In the paradigm, participants received a priming dose of alcohol and then entered a 120-min resist phase, in which they received monetary rewards if they resisted self-administering alcohol. We used Cox proportional hazards regression to determine the impact of craving and Impaired Control Scale scores on rate of lapse. Results: 64.7% of participants across both versions of the paradigm were unable to resist alcohol for the duration of the session. Craving at baseline (HR = 1.07, 95% CI 1.01-1.13, p = 0.02) and following priming (HR = 1.08, 95% CI 1.02-1.15, p = 0.01) were associated with rate of lapse. Individuals who lapsed endorsed greater attempts to control their drinking over the prior six months compared to individuals who resisted. Conclusions: This study provides preliminary evidence that craving may be predictive of risk of lapse in individuals who are trying to limit alcohol intake after consuming a small initial amount of alcohol. Future studies should test this paradigm in a larger and more diverse sample.

RESUMO

BACKGROUND: The Veterans Health Administration (VHA), 1 of 3 administrative branches in the US Department of Veterans Affairs (VA), is the largest integrated health care system in the United States. The VHA has 4 missions: providing health care to eligible veterans; supporting research to benefit veterans and the larger society; providing education for health care trainees; and supporting emergency response. OBSERVATIONS: In service of these goals, the VA has academic affiliations with training institutions throughout the country, offering unique and extensive training and research opportunities. These affiliations are a 2-way street where both the VA and the affiliate provide and gain from their partnership. For example, VA affiliations with University of California (UC) medical schools benefit veteran care and are a major contributor to the UC academic mission. This article explores the history of the VA, current veteran demographics and needs, academic affiliations, and the integrated care model of training in all VHA facilities. The VA and UC academic affiliation system is described further with regard to shared research and educational functions. CONCLUSIONS: We identify risks to academic affiliations if a shift occurs from VHA care to VA-managed community-based care following the implementation of recent legislation. We also provide suggestions for VA academic affiliates to help assess and guide the potential impact of increased VA-managed community care.

RESUMO

INTRODUCTION: Many African Americans live in communities with a disproportionately high density of tobacco advertisements compared to Whites. Some research indicates that point-of-sale advertising is associated with impulse purchases of cigarettes and smoking. Ecological Momentary Assessment (EMA) can be used to examine associations between tobacco advertisement exposure and smoking variables in the natural environment. METHODS: Non-treatment seeking African American smokers were given a mobile device for 2weeks (N=56). They were prompted four times per day and responded to questions about recent exposure to tobacco advertisements. Participants were also asked to indicate the number of cigarettes smoked, and if they made any purchase, or an impulse purchase, since the last assessment. Linear mixed models (LMMs) analyzed between- and within-subject associations between exposure and outcomes. RESULTS: Participants reported seeing at least one advertisement on 33% of assessments. Of those assessments, they reported seeing menthol advertisements on 87% of assessments. Between-subject analyses revealed that participants who on average saw more advertisements were generally more likely to report purchasing cigarettes and to purchase cigarettes on impulse. Within-subject analyses revealed that when an individual participant reported seeing more advertisements than usual they were more likely to have reported purchasing cigarettes, making an impulse purchase and smoking more cigarettes during the same period, but not the subsequent time period. CONCLUSIONS: Many African American smokers are frequently exposed to pro-tobacco marketing. Advertisement exposure is cross-sectionally associated with impulse purchases and smoking. Future research should assess prospective associations in more detail.

RESUMO

OBJECTIVE: Most smokers want to quit but most cessation attempts end in failure. Alcohol consumption is associated with smoking behavior and relapse. We examined the associations between severity of drinking and psychological processes during a cessation attempt in the laboratory and during a quit attempt. METHODS: Smokers (N=209) enrolled in a smoking cessation study were followed from 2 weeks pre-quit through 4 weeks post-quit. Participants scoring 0-7 and 8-15 on the Alcohol Use Disorders Identification Test (AUDIT) were classified as low-risk and high-risk drinkers, respectively. Participants attended one pre-quit laboratory session before which they were required to abstain from smoking and another pre-quit session before which they smoked normally. Craving was assessed in the laboratory with the Questionnaire for Smoking Urges (QSU). A subsample of the participants also completed a 1-week ecological momentary assessment (EMA) study starting on the quit day. During EMA, craving for cigarettes was assessed, and attentional bias was assessed using a smoking Stroop task (n=119). RESULTS: High (vs. low) risk participants reported greater abstinence-induced increases in craving in the laboratory, and also exhibited greater attentional bias on the smoking Stroop task during EMA. CONCLUSIONS: High-risk drinkers exhibited a stronger increase in desire to smoke in abstinence and greater attentional bias to smoking cues early in a quit attempt, both of which may motivate continued smoking behaviors. High-risk drinkers may require more intensive or different smoking cessation interventions.

RESUMO

African American cigarette smokers have lower rates of cessation than Whites and live in communities with a higher number of tobacco advertisements. Exposure to smoking cues may promote smoking and undermine cessation. It may be possible to reduce attention to smoking cues ("attentional bias"). In this study, we investigated the effect of attentional retraining (AR) on attentional bias and smoking in African American smokers. Nontreatment- seeking African American smokers (N = 64) were randomly assigned to an AR or control condition. Participants were given a mobile device for 2 weeks and prompted to complete up to 3 AR (or control) trainings per day. Participants completed assessments of attentional bias, craving, and smoking both in the lab and in the field. Participants in the AR and control conditions completed an average of 29.07 AR (SD = 12.48) and 30.61 control training tasks (SD = 13.07), respectively. AR reduced attentional bias assessed in the laboratory, F(1, 126) = 9.20, p = .003, and field, F(1, 374) = 6.18, p = .01. This effect generalized to new stimuli, but not to new tasks. AR did not significantly reduce craving or biological measures of smoking. Smoking assessed on the mobile device declined over days in the AR group, F(1, 26) = 10.95, p = .003, but not in the control group, F(1, 27) = 0.02, p = .89. Two weeks of AR administered on a mobile device reduced attentional bias in African American smokers and had mixed effects on smoking. (PsycINFO Database Record

RESUMO

BACKGROUND: Post-traumatic stress disorder (PTSD) is often comorbid with alcohol dependence (AD), but little is known about the characteristics of AD treatment-seeking inpatients with PTSD. We examined differences between treatment-seeking alcohol dependent inpatients with and without comorbid PTSD. We hypothesized that those with AD and PTSD would have higher levels of: (1) alcohol use and AD severity; (2) anxiety and mood disorders; (3) neuroticism. METHODS: Individuals (N=411, mean age=41.7±10.0years) with AD were monitored over 30days in a suburban inpatient alcohol treatment setting. Patients were evaluated to identify AD and comorbid PTSD, mood and anxiety disorders, alcohol use and dependence severity, personality, and aggression. RESULTS: Those with PTSD (19% of the sample) did not differ in the amount of alcohol consumed, but had greater: (1) severity of AD (p=0.001, d=0.44); (2) diagnosis of anxiety (p=0.000, OR=3.64) and mood (p=0.000, OR=4.83) disorders; and (3) levels of neuroticism (p<0.001, d=0.67) and aggression (p<0.001, d=0.81). CONCLUSIONS: AD patients with comorbid PTSD present a more severe phenotype across AD severity, frequency of anxiety and mood disorders, and levels of neuroticism and aggression. This group may benefit from concurrent treatment of both AD and PTSD. Future research can investigate neuroticism as a potential treatment target.
