Abstract
Alcoholic beverages are common components of diets worldwide and understanding their effects on humans' health is crucial. Because hypertension is the leading risk factor for cardiovascular diseases and all-cause mortality, the relationship of alcohol consumption with blood pressure (BP) has been the subject of extensive investigation. For the purpose of this review, we searched the terms "alcohol", "ethanol", and "arterial hypertension" on Pubmed MeSH and selected the most relevant studies. Short-term studies showed a biphasic BP response after ingestion of high doses of alcohol, and sustained alcohol consumption above 30 g/day, significantly, and dose-dependently, increased the risk for hypertension. These untoward effects of alcoholic beverages on BP can be mediated by a multiplicity of neurohormonal mechanisms. In addition to the effects on BP, excess alcohol intake might contribute to cardiac and renal hypertensive organ damage, although some studies suggest possible benefits of moderate alcohol consumption on additional cardiovascular risk factors, such as diabetes and lipoprotein(a). Some intervention studies and cumulative analyses support the evidence of a benefit of the reduction/withdrawal of alcohol consumption on BP and cardiovascular outcomes. This is why guidelines of scientific societies recommend avoidance or limitation of alcohol intake below one unit/day for women and two units/day for men. This narrative article overviews all these topics, providing an update of the current knowledge on the relationship between alcohol and BP.

Abstract
Alcohol misuse is common in many societies worldwide and is associated with extensive morbidity and mortality, often leading to alcohol use disorders (AUD) and alcohol-related end-organ damage. The underlying mechanisms contributing to the development of AUD are largely unknown; however, growing evidence suggests that alcohol consumption is strongly associated with alterations in DNA methylation. Identification of alcohol-associated methylomic variation might provide novel insights into pathophysiology and novel treatment targets for AUD. Here we performed the largest single-cohort epigenome-wide association study (EWAS) of alcohol consumption to date (N = 8161) and cross-validated findings in AUD populations with relevant endophenotypes, as well as alcohol-related animal models. Results showed 2504 CpGs significantly associated with alcohol consumption (Bonferroni p value < 6.8 × 10-8) with the five leading probes located in SLC7A11 (p = 7.75 × 10-108), JDP2 (p = 1.44 × 10-56), GAS5 (p = 2.71 × 10-47), TRA2B (p = 3.54 × 10-42), and SLC43A1 (p = 1.18 × 10-40). Genes annotated to associated CpG sites are implicated in liver and brain function, the cellular response to alcohol and alcohol-associated diseases, including hypertension and Alzheimer's disease. Two-sample Mendelian randomization confirmed the causal relationship of consumption on AUD risk (inverse variance weighted (IVW) p = 5.37 × 10-09). A methylation-based predictor of alcohol consumption was able to discriminate AUD cases in two independent cohorts (p = 6.32 × 10-38 and p = 5.41 × 10-14). The top EWAS probe cg06690548, located in the cystine/glutamate transporter SLC7A11, was replicated in an independent cohort of AUD and control participants (N = 615) and showed strong hypomethylation in AUD (p < 10-17). Decreased CpG methylation at this probe was consistently associated with clinical measures including increased heavy drinking days (p < 10-4), increased liver function enzymes (GGT (p = 1.03 × 10-21), ALT (p = 1.29 × 10-6), and AST (p = 1.97 × 10-8)) in individuals with AUD. Postmortem brain analyses documented increased SLC7A11 expression in the frontal cortex of individuals with AUD and animal models showed marked increased expression in liver, suggesting a mechanism by which alcohol leads to hypomethylation-induced overexpression of SLC7A11. Taken together, our EWAS discovery sample and subsequent validation of the top probe in AUD suggest a strong role of abnormal glutamate signaling mediated by methylomic variation in SLC7A11. Our data are intriguing given the prominent role of glutamate signaling in brain and liver and might provide an important target for therapeutic intervention.

Abstract
Head and neck cancer (HNC) concerns more than 890,000 patients worldwide annually and is associated with the advanced stage at presentation and heavy outcomes. Alcohol drinking, together with tobacco smoking, and human papillomavirus infection are the main recognized risk factors. The tumorigenesis of HNC represents an intricate sequential process that implicates a gradual acquisition of genetic and epigenetics alterations targeting crucial pathways regulating cell growth, motility, and stromal interactions. Tumor microenvironment and growth factors also play a major role in HNC. Alcohol toxicity is caused both directly by ethanol and indirectly by its metabolic products, with the involvement of the oral microbiota and oxidative stress; alcohol might enhance the exposure of epithelial cells to carcinogens, causing epigenetic modifications, DNA damage, and inaccurate DNA repair with the formation of DNA adducts. Long-term markers of alcohol consumption, especially those detected in the hair, may provide crucial information on the real alcohol drinking of HNC patients. Strategies for prevention could include food supplements as polyphenols, and alkylating drugs as therapy that play a key role in HNC management. Indeed, polyphenols throughout their antioxidant and anti-inflammatory actions may counteract or limit the toxic effect of alcohol whereas alkylating agents inhibiting cancer cells' growth could reduce the carcinogenic damage induced by alcohol. Despite the established association between alcohol and HNC, a concerning pattern of alcohol consumption in survivors of HNC has been shown. It is of primary importance to increase the awareness of cancer risks associated with alcohol consumption, both in oncologic patients and the general population, to provide advice for reducing HNC prevalence and complications.

Abstract
BACKGROUND Hypertension is the leading cause of cardiovascular disease morbidity and mortality worldwide. Its struggle involves knowing its prevalence. Insufficient data on hypertension in adults in Lubumbashi, Democratic Republic of Congo (DRC), prompted the conduct of this study. The objectives were to determine the prevalence of hypertension and to identify the associated factors in adults in Lubumbashi. Methodology. A cross-sectional study was carried out among 6,708 adults from October 15th to November 24th, 2018, in Lubumbashi. Anthropometric data, lifestyle, and medical history were collected. Hypertension was defined when the mean of the last two blood pressure (BP) measurements was greater than or equal for systolic (SBP) at 140 mmHg and for diastolic (DBP) at 90 mmHg or a history of taking antihypertensive medication whatever the value of the BP. Logistic regression was used to identify the relative effects of hypertension risk factors and all statistical tests were declared significant at a p value <0.05. RESULTS The female participants numbered 4479 (66.8%). The mean age of all participants was 47.9 ± 16.5 years. The mean SBP and DBP were 128.4 ± 25.9 mmHg and 79.1 ± 15.3 mmHg, respectively. The overall prevalence of hypertension was 33.6%. This prevalence was statistically higher in women than in men (34.5% vs. 31.7%; p=0.024). After logistic regression, the risk of hypertension increased with age >50 years (aOR = 5.85 [5.19-6.60]), overweight (aOR = 1.25 [1.11-1.41]), obesity (aOR = 1.25 [1.11-1.41]), central obesity (aOR = 1.37 [1.16-1.61]), diabetes mellitus (aOR = 2.19 [1.63-2.95]), alcohol consumption (aOR = 1.21 [1.05-1.39]), nonconsumption of vegetables (aOR = 1.35 [1.02-1.80]), and history of stroke (aOR = 2.57 [1.88-3.51]). Hypertension was inversely associated with being underweight (aOR = 0.68 [0.53-0.87]). CONCLUSION The prevalence of hypertension in the city of Lubumbashi is high as in other cities of the DRC and Africa. This situation requires the implementation of prevention, detection, and treatment programs for hypertension.

BNP worsens 12 days after alcohol cessation while other cardiovascular risk biomarkers improve: An observational study. Alcohol 2021; 90:39-43.

Abstract
Subjects with alcohol use disorder (AUD) display a high prevalence of cardiovascular risk factors (CRFs), and a high incidence of cardiovascular diseases associated with an earlier mortality. Abstinence has long-term cardiovascular and global health benefits. However, few studies have examined the short-term effect of alcohol cessation on cardiac function and key CRFs. The aim of the study was to assess brain natriuretic peptide (BNP) and other CRFs on admission for alcohol cessation and 12 days later, in inpatients with AUD. A retrospective chart review of inpatients hospitalized for alcohol cessation was conducted. Patients who did not relapse at day 12 were included. We compared, at entry and at day 12, BNP and other CRFs: hemodynamic and electromyographic variables, lipid, homocysteine level, and liver enzymes at entry and at day 12. Wilcoxon, Student tests, and repeated-measures ANOVA were conducted. Fifty-five patients were included (38 males, mean age 50.5 years, alcohol per day 60 g-750 g, 44 current tobacco smokers). BNP was significantly increased (11.8 pg/mL [±16.2] to 35.5 pg/mL [±47.6], p < 0.001). Repeated-measure ANOVA showed a significant between-subject effect (p = 0.024), but no significant interaction between BNP variation and having a BNP at entry >10 pg/mL (p = 0.092). In contrast, a significant improvement on 8 of 13 other CRFs and liver enzymes measures was observed (p ≤ 0.05). A rapid improvement of several CRFs was confirmed. However, the increase of BNP at day 12 supports its investigation as a possible relevant biomarker of cardiac function in alcohol withdrawal.

Abstract
Introduction: Despite the improved treatment protocol of hypertension, the magnitude of the disease and its related burden remains raised. Hypertension makes up the leading cause of stroke, kidney disease, arterial disease, eye disease, and cardiovascular disease (CVD) growth. Areas covered: This review provides the overview of the role of dietary salt and alcohol use reduction in the management of hypertension, a brief history of alcohol, the vascular endothelium functions, the effects of alcohol use on blood pressure (BP), the mechanisms of alcohol, brief history of salt, the effects of dietary salt intake on BP, and the mechanisms of salt. Expert opinion: Studies found that high dietary salt intake and heavy alcohol consumption have a major and huge impact on BP while both of them have been identified to increase BP. Also, they raise the risk of hypertension-related morbidity and mortality in advance. On the other way, the dietary salt and alcohol use reduction in the management of hypertension are significant in the control of BP and its related morbidity and mortality. Further, studies suggested that the dietary salt and alcohol use reductions are the cornerstone in the management of hypertension due to their significance as part of comprehensive lifestyle modifications.

Abstract
Patient awareness of medical conditions may influence treatment seeking and monitoring of these conditions. Accurate awareness of hypertension reported to clinicians evaluating patients for whom clinical history is limited, such as in emergency care, can aid in diagnosis by revealing whether measured hypertension is typical or atypical. Measurement of blood pressure in a laboratory study was assessed at rest, immediately before phlebotomy, and within 10 minutes after. The resting measure was used to determine the accuracy of self-reported hypertension in 283 adults. Parametric analyses were conducted to identify potential variables influencing accuracy of self-reported hypertension. Sensitivity, specificity, and the kappa coefficient of agreement were calculated to determine the influence of alcohol dependence (AD), sex, age, and cigarette smoking on hypertension awareness. Self-report was mildly sensitive, correctly identifying individuals with hypertension in approximately 37% of the cases, but was highly specific (95%) in identifying individuals without hypertension. Similar sensitivities were found in analyses separated by sex. Sensitivity was greater in those over age 55 (53%) in comparison with those <54, as well as in those who were not smoking. Comparison of those with and without a history of AD revealed that both groups show similar accuracy in reporting hypertension. Absence of hypertension can be accurately determined with self-report data in those without hypertension. A significant proportion of those with measured hypertension report an absence of hypertension.

Abstract
Aim: A drinking pattern is not only a major drinking variable, but is also one indicator of a country’s drinking culture. In the present study, we examine drinking patterns within and across the neighbouring countries of Denmark and Germany. The aim of the research is to determine to what extent drinking patterns differ or are shared at the sub-national level in the two countries. Method: Data came from the German 2012 Epidemiological Survey of Substance Use (n = 9084) 18–64 years (response rate 54%), and the Centre for Alcohol and Drug Research’s 2011 Danish national survey (n = 5133) 15–79 years (response rate 64%), which was reduced to a common age range, producing a final n = 4016. The drinking pattern variable included abstention, moderate drinking, heavy drinking, risky single occasion drinking (RSOD), and was investigated with bivariate statistics and gender-specific hierarchical cluster analysis. Results: For men three clusters emerged: one highlighting abstention and RSOD, moderate/heavy drinking, RSOD and RSOD + heavy drinking. For women, two clusters appeared: one highlighting abstention and moderate/heavy drinking and the other highlighting RSOD and RSDO + heavy drinking. The clusters revealed different geographical patterning: for men, a west vs. east divide; for women, a north–south gradient. Conclusions: The analysis could identify for each gender clusters representing both separate and shared drinking patterns as well as distinctive geographical placements. This new knowledge can contribute to a new understanding of the dynamics of drinking cultures and could indicate new approaches to prevention efforts and policy initiatives.

Abstract
INTRODUCTION To examine the impact of cessation of an internet session on skin conductance responses and anxiety of higher and lower problem internet users, in order to explore possible physiological withdrawal effects. METHOD Participants were measured in terms of their skin conductance before (15min), during (15min), and after (15min) an internet session, and completed self-report measures of state anxiety and problematic internet use. RESULTS Higher, but not lower, problem users showed increased skin conductance after internet use was stopped, relative to before their internet session. Higher problem users' GSR scores increased, as the time from internet cessation became longer. Higher problem users also showed increased levels of anxiety, following their internet session, which correlated with their skin conductance scores. CONCLUSIONS These results suggest that, following termination of an internet session, withdrawal-like effects are seen, both psychologically and physiologically.

PLoS One 2017; 12:e0178480. [PMID: 28542470 PMCID: PMC5444838 DOI: 10.1371/journal.pone.0178480] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2017] [Accepted: 05/12/2017] [Indexed: 11/18/2022] Open
Abstract
Problematic internet use (PIU) has been suggested as in need of further research with a view to being included as a disorder in future Diagnostic and Statistical Manual (DSM) of the American Psychiatric Association, but lack of knowledge about the impact of internet cessation on physiological function remains a major gap in knowledge and a barrier to PIU classification. One hundred and forty-four participants were assessed for physiological (blood pressure and heart rate) and psychological (mood and state anxiety) function before and after an internet session. Individuals also completed a psychometric examination relating to their usage of the internet, as well as their levels of depression and trait anxiety. Individuals who identified themselves as having PIU displayed increases in heart rate and systolic blood pressure, as well as reduced mood and increased state of anxiety, following cessation of internet session. There were no such changes in individuals with no self-reported PIU. These changes were independent of levels of depression and trait anxiety. These changes after cessation of internet use are similar to those seen in individuals who have ceased using sedative or opiate drugs, and suggest PIU deserves further investigation and serious consideration as a disorder.

Ethanol withdrawal increases oxidative stress and reduces nitric oxide bioavailability in the vasculature of rats. Alcohol 2015; 49:47-56.

Abstract
We analyzed the effects of ethanol withdrawal on the vascular and systemic renin-angiotensin system (RAS) and vascular oxidative stress. Male Wistar rats were treated with ethanol 3-9% (v/v) for a period of 21 days. Ethanol withdrawal was induced by abrupt discontinuation of the treatment. Experiments were performed 48 h after ethanol discontinuation. Rats from the ethanol withdrawal group showed decreased exploration of the open arms of the elevated-plus maze (EPM) and increased plasma corticosterone levels. Ethanol withdrawal significantly increased systolic blood pressure and plasma angiotensin II (ANG II) levels without an effect on plasma renin activity (PRA), angiotensin converting enzyme (ACE) activity, or plasma angiotensin I (ANG I) levels. No differences in vascular ANG I, ANG II levels, and ACE activity/expression and AT1 and AT2 receptor expression were detected among the experimental groups. Plasma osmolality, as well as plasma sodium, potassium, and glucose levels were not affected by ethanol withdrawal. Ethanol withdrawal induced systemic and vascular oxidative stress, as evidenced by increased plasma thiobarbituric acid-reacting substances (TBARS) levels and the vascular generation of superoxide anion. Ethanol withdrawal significantly decreased plasma and vascular nitrate/nitrite levels. Major new findings of the present study are that ethanol withdrawal induces vascular oxidative stress and reduces nitric oxide (NO) levels in the vasculature. Additionally, our study provides novel evidence that ethanol withdrawal does not affect the vascular ANG II generating system while stimulating systemic RAS. These responses could predispose individuals to the development of cardiovascular diseases.

Abstract
Alcohol is a major contributor to the global burden of disease, disability, and death in high, middle, and low-income countries. Harmful use of alcohol is one of the main factors contributing to premature deaths and avoidable disease burden worldwide and has a major impact on public health. The aim of this present cross-sectional study was to investigate the effect of alcohol consumption on coagulation parameters and liver enzymes of subjects in Port Harcourt, Nigeria. Two hundred adults consisting of 120 alcohol dependent subjects and 80 age, gender-matched nondrinkers aged 25-65 years (mean age 45.25 ± 11.50 years) were enrolled in this study. Of the 120 chronic alcohol drinkers, 37 were dependent on local dry gin, while 83 were dependent on other alcoholic beverages. The mean values of the liver enzymes, aspartate aminotransferase and gamma glutamyl transferase, were significantly higher (P = 0.002 and P = 0.02 respectively) among the chronic alcohol consumers compared with their nondrinker counterparts. Although the value of alanine aminotransferase was higher in the chronic drinkers, it did not reveal any significant difference (P = 0.11). The coagulation parameters, prothrombin time and activated partial thromboplastin time were investigated among chronic drinkers and nondrinkers. The mean value of prothrombin time and activated partial thromboplastin time was significantly higher in the chronic alcohol drinkers compared to the nondrinkers (P = 0.04 and P = 0.02 respectively). We observed a positive and significant correlation between values of liver enzymes, serum gamma glutamyl transferase and aspartate aminotransferase, and values of prothrombin time among alcohol consumers (r = 0.72 and r = 0.68 respectively). The implementation of policies to target harm reduction strategies among alcoholics is urgently needed, alongside the building of a strong base of public awareness and community support required for the continuity and sustainability of alcohol policies. There is also the need for the Nigerian government to enforce tighter regulations and restrictions on the production and distribution of alcoholic beverages to reduce harmful use, and protect young people and other vulnerable groups.

Abstract
BACKGROUND AND OBJECTIVES Alcohol and nicotine dependence are serious public health problems worldwide. They are associated with substantial morbidity and mortality, as well as adverse social effects and increased healthcare costs. Although efficacious treatments are available for these disorders, additional therapeutic options are required to ensure greater treatment utilization. In this paper, we describe the empirical basis on which varenicline, a nicotinic partial agonist approved for smoking cessation, may also have utility in the treatment of alcohol addiction. METHODS We sought to identify papers examining nicotine dependence, alcohol dependence, smoking, alcohol, and varenicline for possible inclusion in the present review. We identified over 600 papers through Pubmed/Medline, PsychINFO, and Google Scholar. We found 12 papers taking into consideration the following criteria: original language English, varenicline effect on alcohol consumption. RESULTS Animal studies have shown that varenicline reduces alcohol consumption. Two recent studies showed that varenicline also reduces alcohol consumption in humans. Both nicotine and alcohol interact with α4β2 and α3β4 nicotinic acetylcholine (ACh) receptors located in the ventral tegmental area of the brain, inducing dopamine (DA) release at the nucleus accumbens. Varenicline binds to nicotinic ACh receptors, where it has partial agonist effects, producing a moderate and constant level of DA release both in the mesolimbic pathway and in the prefrontal cortex. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE Through these effects, varenicline may reduce alcohol craving, seeking, and consumption, in addition to promoting smoking cessation. Additional studies are needed to confirm the efficacy of varenicline in the treatment of alcohol dependence.

Abstract
BACKGROUND Stress, alcohol cues, and dysregulated stress responses increase alcohol craving and relapse susceptibility, but few pharmacologic agents are known to decrease stress- and cue-induced alcohol craving and associated stress dysregulation in humans. Here we report findings from a preliminary efficacy study of the alpha-1 receptor antagonist, prazosin, in modulating these relapse-relevant factors in alcohol-dependent individuals. METHODS Seventeen early abstinent, treatment-seeking alcohol-dependent individuals (12 men and 5 women) were randomly assigned to receive either placebo or 16 mg daily prazosin in a double-blind, placebo-controlled manner over 4 weeks. During week 4, all patients participated in a 3-day laboratory experiment involving 5-minute guided imagery exposure to stress, alcohol cue, and neutral-relaxing/control conditions, 1 exposure per day, on consecutive days in a random, counterbalanced order. Alcohol craving, anxiety, negative emotion, cardiovascular measures, and plasma hypothalamic-pituitary-adrenal (HPA; cortisol, adenocorticotropic hormone) were assessed repeatedly in each session. RESULTS The prazosin group (n = 9) versus the placebo group (n = 8) showed significantly lower alcohol craving, anxiety, and negative emotion following stress exposure. The placebo group also showed significantly increased stress- and cue-induced alcohol craving, anxiety, negative emotion, and blood pressure (BP), as well as a blunted HPA response relative to the neutral condition, while the prazosin group showed no such increases in craving, anxiety, negative emotion, and BP, and no blunted HPA response to stress and alcohol cue exposure. CONCLUSIONS Prazosin appears efficacious in decreasing stress- and cue-induced alcohol craving and may normalize the stress dysregulation associated with early recovery from alcoholism. Further research to assess the efficacy of prazosin in reducing alcohol craving and stress-related relapse risk is warranted.

Abstract
BACKGROUND Bearing in mind the mechanisms involved in nonalcoholic fatty liver disease, this study aims to verify whether metabolic syndrome or its various individual components are independent predictive factors for steatosis > or =10% in alcoholic patients. METHODS This study included 281 consecutive alcoholic patients with abnormal liver tests and either normal liver histology or steatosis <10% (n = 119) or steatosis > or =10% (n = 162). Logistic regression analysis was used to study the relationship between metabolic syndrome components and various risk factors and the presence of steatosis > or =10%. We assessed apolipoprotein A1 (ApoA-1) levels, a major protein component of plasma high-density lipoprotein (HDL), rather than HDL-cholesterol levels. RESULTS Plasma ApoA-1 levels (p < 0.01), body mass index (BMI) (p < 0.01), and waist circumference (p < 0.05) were significantly higher in patients with steatosis > or =10% than in patients with normal liver histology or steatosis <10%. A higher percentage of patients with steatosis > or =10% had high blood pressure (p = 0.003) than patients with normal liver histology or steatosis <10%. In the logistic regression, ApoA-1 [odds ratio (OR) = 1.57 (1.10-2.22)], BMI [OR = 1.10 (1.01-1.23)], and high blood pressure [OR = 1.84 (1.10-3.06)] were positively and independently correlated with the presence of steatosis > or =10%. In the multivariate regression high blood pressure was independently and positively correlated with steatosis score (r = 0.55 +/- 0.26; p < 0.05). On the other hand, when the presence of high blood pressure was the dependent variable, the presence of steatosis > or =10% positively and independently correlated with it [OR = 1.82 (1.05-3.15)]. CONCLUSION In alcoholic patients without fibrosis, ApoA-1, BMI, and high blood pressure on the next morning after the admission were predictive of steatosis > or =10%. High blood pressure was the only metabolic syndrome component associated with the presence of alcoholic steatosis >/=10% and was not correlated with other metabolic syndrome components. These findings suggest that steatosis mechanisms are different in alcoholic and nonalcoholic fatty liver.

Abstract
BACKGROUND Research has shown that exposure to stress/negative affect and to alcohol cues can each increase alcohol craving and relapse susceptibility in alcohol-dependent individuals. However, whether the emotional and physiological states associated with stress-induced and alcohol cue-induced craving are comparable has not been well studied. Therefore, this study examined the craving, emotional, and physiological responses to stress and to alcohol cues in treatment-engaged, 4-week abstinent, alcohol-dependent individuals using analogous stress and alcohol cue imagery methods. METHOD Twenty treatment-seeking, alcohol-dependent participants (18 males/2 females) were exposed to a brief 5-minute guided imagery procedure that involved imagining a recent personal stressful situation, a personal alcohol cue-related situation, and a neutral-relaxing situation, 1 imagery per session presented in random order. Alcohol craving, anxiety and emotion rating scales, cardiovascular measures, and salivary cortisol were compared across the 3 conditions. RESULTS Exposure to stress and to alcohol cues each produced significant increases in alcohol craving, anxiety, and negative emotions and decreases in positive emotions. Stress-induced alcohol craving was significantly correlated with increases in sadness, anger, and anxiety ratings, but alcohol cue-induced craving was associated with decreases in positive affect (joy and neutral relaxed state) and increases in anxiety and fear ratings. Furthermore, stress increased systolic and diastolic blood pressure responses, but significant increases in salivary cortisol were only observed in the alcohol cue condition. CONCLUSIONS Although both stress and alcohol cues produce increases in anxiety associated with alcohol craving, each produced a dissociable psychobiological state involving subjective emotional, cardiovascular, and cortisol responses. These data could have significant implications for understanding the specific psychobiology associated with stress or alcohol cue exposure and their potential effects on alcohol relapse susceptibility.
