Diagnosis Of Alcohol Use Disorder Research Articles

Discussing alcohol use with the GP: a qualitative study.

BackgroundDespite most GPs recognising their role in the early diagnosis of alcohol use disorder (AUD), only 23% of GPs routinely screen for alcohol use. One reason GPs report for not screening is their relationship with patients; questions regarding alcohol use are considered a disturbance of a relationship built on mutual trust.AimTo analyse the feelings and experiences of patients with AUD concerning early screening for alcohol use by GPs.Design & settingA qualitative study of patients (n = 12) with AUD in remission or treatment, recruited from various medical settings.MethodSemi-structured interviews were conducted, audiorecorded, and transcribed verbatim. The authors conducted an inductive analysis based on grounded theory. The analysis was performed until theoretical data saturation was reached.ResultsThe participants experienced AUD as a chronic, destructive, and shameful disease. The participants expected their GPs to play a primary role in addressing AUD by kind listening, and providing information and support. If the GPs expressed a non-judgmental attitude, the participants could confide in them; this moment was identified as a key milestone in their trajectory, allowing relief and a move toward treatment. The participants thought that any consultation could be an opportunity to discuss alcohol use and noted that such discussions required a psychological and benevolent approach.ConclusionThe participants felt fear or denial from the GPs, even though they felt that discussing alcohol use is part of the GP’s job. The participants requested that GPs adopt non-judgmental attitudes and kindness when approaching the subject of alcohol use.

Eating disorders in a community-based sample of women with alcohol use disorder and nicotine dependence

BackgroundStudies consistently report a higher prevalence of substance use disorders (SUDs) among women with eating disorders than control women. However, limited research exists on the prevalence of eating disorder symptoms and diagnoses in women with SUDs, especially in community-based populations. We examined the prevalence of eating disorder symptoms and diagnosis by the presence or absence of lifetime alcohol use disorder (AUD) and/or nicotine dependence (ND) in a community-based sample of women. Methods3756 women (median age = 22 years) from the Missouri Adolescent Female Twin Study completed a modified semi-structured interview assessing lifetime DSM-IV psychiatric disorders and SUDs. Logistic regression models adjusted for demographic characteristics and other psychopathology, and robust standard errors accounted for the non-independence of twin data. ResultsIn general, women with comorbid AUD and ND had a higher prevalence of eating disorder symptoms and diagnoses than women with AUD or ND Only, who in turn had a higher prevalence than those without either SUD. After adjustment for covariates, women with AUD and ND had significantly greater risk of broad anorexia nervosa (RRR = 3.17; 99 % CI = 1.35, 7.44), purging disorder (2.59; 1.24, 5.43), and numerous eating disorder symptoms than women with neither disorder. Significant differences emerged between individuals with both AUD and ND versus women with AUD Only or ND Only for some eating disorder symptoms. ConclusionsWomen with lifetime AUD or ND diagnoses are at high risk for eating disorder symptoms and diagnoses, underscoring the importance of assessing eating disorder symptoms among women with these disorders.

Interaction between behavioral inhibition and neural alcohol cue-reactivity in ADHD and alcohol use disorder

RationaleCompared to the general population, adult Attention-Deficit / Hyperactivity Disorder (ADHD) is more prevalent in patients with Alcohol Use Disorder (AUD). Impaired behavioral inhibition is a common characteristic in both ADHD and AUD. Relapse risk is increased in patients with AUD and comorbid, untreated ADHD and in AUD patients with increased neural cue-reactivity.ObjectivesIn this study, we examined the interaction between neural correlates of behavioral inhibition and alcohol cue-reactivity with a hybrid imaging task.MethodsOut of 69 adult study participants, we included n = 49 in our final analyses: Individuals had a diagnosis of either AUD (n = 13), ADHD (n = 14) or both (n = 5), or were healthy controls (HC; n = 17). The functional magnetic resonance imaging paradigm aimed to examine the combined effects of both an interference-inhibition task (“Simon-task”) and an alcohol cue-reactivity task. Instead of segregating by diagnostic group, we pursued a dimensional approach in which we compared measures of AUD and ADHD severity, as well as the interaction of both, using multiple regression analyses.ResultsThe four groups did not differ on the behavioral level on either the inhibition task or the alcohol cue-reactivity task. However, brain activation in frontal control and reward-related regions during completion of the combined tasks were related to ADHD and AUD severity (symptom load). During presentation of both alcohol cues and the inhibition task, participants with higher AUD and ADHD symptom load exhibited greater BOLD (blood oxygen level dependent) responses in subcortical reward-related regions.ConclusionsOur findings support the hypothesis that ADHD additionally diminishes inhibition ability in individuals with AUD. This may increase relapse risk when confronted with alcohol cues. Further, it is crucial for patients with comorbid AUD and ADHD to take into account not only reduced cognitive control over behavioral inhibition but also simultaneously heightened alcohol cue-reactivity.

Emotional difficulties among individuals with alcohol use disorder: the mediating role of psychological mechanisms linked to mindfulness

ABSTRACT Background: Difficulties with emotion regulation (DER) and emotional distress (ED) are considered relevant clinical features of Alcohol Use Disorder (AUD) and other Substance Use Disorders (SUDs). Psychological mechanisms linked to mindfulness are involved in addressing DER and ED. This study aims at investigating the mediating role of mindfulness on relationship between DER and ED among individuals with AUD and concurrent SUDs. Methods: Eighty-seven individuals with a primary diagnosis of AUD, who completed a mindfulness-based treatment for this condition, were included. DER, ED, and mindfulness dimensions were self-report assessed. Results: The analyses showed significant and positive indirect effects of mindfulness dimensions (i.e., self-regulation of attention, non-reactive awareness). The direct effect of DER on ED was significant. Conclusion: The self-regulation of attention and non-reactive awareness linked to mindfulness are relevant and stable protective factors for emotional difficulties among individuals with AUD. Longitudinal studies are needed to empirically test the therapeutic role of these mindfulness dimensions in the treatment of SUDs and in relapse prevention.

Alcohol use disorders and the brain.

A diagnosis of alcohol use disorder is associated with a higher risk of dementia, but a dose-response relationship between alcohol intake consumption and cognitive impairment remains unclear. Alcohol is associated with a range of effects on the central nervous system at different doses and acts on a number of receptors. Acute disorders include Wernicke's encephalopathy (WE), traumatic brain injury, blackouts, seizures, stroke and hepatic encephalopathy. The most common manifestations of chronic alcohol consumption are Korsakoff's syndrome (KS) and alcohol-related dementia (ARD). There is limited evidence for benefit from memantine in the treatment of ARD, but stronger evidence for the use of high-dose parenteral thiamine in the progression of neuropsychiatric symptoms for WE. Accumulating evidence exists for pharmacological treatment in the prevention of hepatic encephalopathy. Rehabilitation of people with ARD may take several years, and requires an approach that addresses physical and psychosocial factors.

Combinatorial Optimization of Clustering Decisions: An Approach to Refine Psychiatric Diagnoses

Using complete enumeration (e.g., generating all possible subsets of item combinations) to evaluate clustering problems has the benefit of locating globally optimal solutions automatically without the concern of sampling variability. The proposed method is meant to combine clustering variables in such a way as to create groups that are maximally different on a theoretically sound derivation variable(s). After the population of all unique sets is permuted, optimization on some predefined, user-specific function can occur. We apply this technique to optimizing the diagnosis of Alcohol Use Disorder. This is a unique application, from a clustering point of view, in that the decision rule for clustering observations into the “diagnosis” group relies on both the set of items being considered and a predefined threshold on the number of items required to be endorsed for the “diagnosis” to occur. In optimizing diagnostic rules, criteria set sizes can be reduced without a loss of significant information when compared to current and proposed, alternative, diagnostic schemes.

Age-related differences in the associations among at-risk drinking, alcohol use disorder, and psychological distress across the adult lifespan: a nationwide representative study in South Korea.

To investigate age-related differences in the relationships among at-risk alcohol consumption, alcohol use disorder (AUD), and psychological distress with a special focus on older adults. We used a nationwide cross-sectional study of a representative sample of community-dwelling adults from the Korean Epidemiologic Catchment Area study for psychiatric disorders conducted by door-to-door interviews. The Korean version of the Composite International Diagnostic Interview was applied. Subjects were categorized into four age groups: young-to-middle-aged (20-54years), near-old (55-64years), early-old (65-74years), and late-old (≥ 75years). The associations among at-risk drinking, alcohol use disorder, and psychological distress were examined according to age groups. Among a total of 5102 individuals, half of them drank alcohol in the previous year, of whom 20.5% were at-risk drinkers (≥ 100g/week). Older people were less often diagnosed with AUD than young-to-middle-aged adults with a similar degree of at-risk drinking. They were less likely to meet the DSM-5 AUD criteria in terms of social and vocational role disruption or creation of a physically hazardous situation. However, at-risk drinking showed a stronger association with subjective psychological distress in older adults, particularly in the near-old group (adjusted odds ratio 1.82, 95% confidence interval 1.09-3.03; p = 0.023). These findings indicate the importance of screening for mental health problems in older adults, especially near-old adults, who drink more than 100g of alcohol per week even when they do not satisfy the criteria for a diagnosis of AUD.

Comorbid alcohol use disorder in psychiatric MDD patients: A five-year prospective study

BackgroundComorbid alcohol use disorder (AUD) is common among patients with major depressive disorder (MDD), and often complicates presentation and treatment. However, there is a scarcity of clinical studies investigating the characteristics and outcome of psychiatric MDD patients with AUD. MethodsIn the Vantaa Depression Study (VDS), a five-year prospective study of psychiatric out- and inpatients (N = 269) with MDD, we investigated the clinical features of MDD, comorbid Axis I and II disorders, psychosocial factors, and long-term outcome of patients with or without AUD. ResultsDepressed patients with comorbid AUD at baseline (n = 66/269, 24.5%) were more often male (OR=3.57, [95% CI 1.72 – 7.41], p = 0.001), had more suicidal ideation (OR=1.06 [1.02 – 1.11], p = 0.008), comorbid panic disorders (OR=3.44 [1.47 – 8.06], p = 0.004), symptoms of any personality disorder (OR=1.04 [1.00 – 1.08], p = 0.038), and more often smoked daily (OR=2.79 [1.32 – 5.88], p = 0.007) than those without. At five years, 13.9% (25/180) still had AUD. More specifically, alcohol abuse was associated with suicide attempts, and dependence with suicidal ideation, and Cluster B personality disorder. Patients with AUD spent more time depressed and had more suicide attempts during follow-up. LimitationsWe did not investigate other substance use disorders. The AUD diagnoses were based on DSM-IV criteria. ConclusionsPsychiatric MDD patients with comorbid alcohol use disorders have characteristics consistent with the epidemiology of AUDs in the general population. They are more often males and smoke, and have more comorbid mental disorders and suicidal behavior. Prospectively they spend more time depressed, thus having worse outcomes than patients without AUDs.

Dialectical behaviour therapy skills training for the treatment of addictive behaviours among individuals with alcohol use disorder: the effect of emotion regulation and experiential avoidance

ABSTRACT Backgrounds Dialectical behavior therapy skills training (DBT-ST) is an effective treatment for alcohol use disorder (AUD). AUD frequently co-occurs with other addictive behaviors. Objective s: These secondary analyses of prior studies on the effectiveness of a 3-month DBT-ST program for AUD investigated pre- post-treatment changes in the severity of concurrent addictive behaviors. The study hypothesized that emotion regulation and experiential avoidance should be the key therapeutic mechanisms involved in the treatment of addictive behaviors. Methods The research included 186 individuals (110 males; 76 females) with a primary diagnosis of AUD. Mediational models were performed considering shorter PROMIS questionnaire subscales (i.e., gambling, sex, shopping, food binging, and starvation) as dependent variables. The difficulties in emotion regulation scale and acceptance and action questionnaire-II total scores were independent and mediator variables, respectively. Results Clinical variables significantly improved during the treatment, independent of baseline levels. Changes in emotion regulation showed significant total effects on improvements in addictive behaviors. Significant indirect effects of changes in experiential avoidance were detected considering compulsive buying and dysfunctional eating behaviors. Conclusion The DBT-ST was a feasible treatment for several addictive behaviors frequently reported by individuals with AUD. The improvements in emotion regulation and experiential avoidance were relevant therapeutic mechanisms involved in the treatment of these conditions. Future controlled trials and follow-up studies are recommended to support the efficacy of DBT-ST as a stand-alone intervention for the treatment of different classes of addictive behaviors.

Chronic repeated predatory stress induces resistance to quinine adulteration of ethanol in male mice

BackgroundTrauma related psychiatric disorders, such as posttraumatic stress disorder (PTSD), and alcohol use disorder (AUD) are highly comorbid illnesses that separately present an opposing, sex-specific pattern, with increased prevalence of PTSD in females and increased prevalence of AUD diagnoses in males. Likewise, PTSD is a risk factor in the development of AUD, with conflicting data on the impact of sex in the comorbid development of both disorders. Because the likelihood of experiencing more than one traumatic event is high, we aim to utilize chronic repeated predatory stress (CRPS) to query the extent to which sex interacts with CRPS to influence alcohol consumption, or cessation of consumption. MethodsMale (n = 16) and female (n = 15) C57BL/6 J mice underwent CRPS or daily handling for two weeks during adolescence (P35-P49) and two weeks during adulthood (P65-P79). Following the conclusion of two rounds of repeated stress, behavior was assessed in the open field. Mice subsequently underwent a two-bottle choice intermittent ethanol access (IEA) assessment (P90-131) with the options of 20 % ethanol or water. After establishing drinking behavior, increasing concentrations of quinine were added to the ethanol to assess the drinking response to adulteration of the alcohol. ResultsCRPS increased fecal corticosterone concentrations and anxiety-like behaviors in the open field in both male and female mice as compared to control mice that had not been exposed to CRPS. Consistent with previous reports, we observed a sex difference in alcohol consumption such that females consumed more ethanol per gram of body mass than males. In addition, CRPS reduced alcohol aversion in male mice such that higher concentrations of quinine were necessary to reduce alcohol intake as compared to control mice. CRPS did not alter alcohol-related behaviors in female mice. ConclusionCollectively, we demonstrate that repeated CRPS can induce anxiety-like behavior in both sexes but selectively influences the response to ethanol adulteration in males.

Mindful self-regulation of attention is a key protective factor for emotional dysregulation and addictive behaviors among individuals with alcohol use disorder

Individuals with alcohol use disorder (AUD) and other substance use disorders (SUDs) frequently show co-occurrent behavioral addictions (BAs) (i.e., gambling and compulsive sex) and other inflexible behaviors (IBs) (i.e., compulsive buying and dysfunctional eating behaviors). The covariation of these conditions might be explained by a role of emotion dysregulation (ED) and executive dysfunctions. This study aims at investigating whether ED and self-regulation of attention (SRA) could be common processes that underpin BAs and other IBs among individuals with AUD. The study hypothesized that SRA should represent a key protective factor for the relationships between ED and BAs/IBs. The research included 319 treatment-seeking individuals with a primary diagnosis of AUD. Five independent multiple parallel mediational models were tested. Self-report instruments were administered in order to assess ED, BAs and other IBs, which represented independent and dependent variables respectively. SRA was self-report assessed and, it was considered the key mediator variable. The analyses highlighted significant total effects of ED on the severity of BAs and IBs. SRA fully mediated the relationships between ED and BAs/IBs, with exception of gambling. ED and SRA should be considered common dimensions that explain the covariation of BAs and IBs among individuals with AUD. SRA represents an adaptive form of emotion regulation that sustains the engagement in goal-oriented behaviors. Future neuroimaging and longitudinal studies are recommended in order to demonstrate the role of ED and SRA on development, maintenance and treatment of BAs and IBs among individuals with SUDs.

Evaluation of childhood traumatic experience as a risk factor for alcohol use disorder in adulthood

BackgroundWe aimed to investigate the effect of early-age (prenatal, infant, and childhood) trauma on adulthood alcohol use disorder.MethodsA total number of 1534 subjects who were born and live in the city of Tangshan were selected. The subjects were divided into three age groups. General demographic data, conditions of the mothers during pregnancy, and condition of the babies at birth, were collected. The diagnosis of alcohol use disorder was based on Structured Clinical Interviews for DSM-IV Axis Disorders (patient version) (SCID). The childhood trauma questionnaire short form (CTQ-SF) [1] and the Lifetime of Experience Questionnaire (LTE-Q) [2] were used to evaluate stress in childhood and adulthood, respectively.ResultsOnly male subjects were diagnosed with lifelong alcohol abuse and alcohol dependence. There was no statistically significant difference in the prevalence of lifetime alcohol use disorder (X2 = 4.480, P = 0.345), current alcohol abuse, and current alcohol dependence among the three groups (X2abuse = 2.177, X2depedence = 2.198, P > 0.05). However, higher prevalence of lifetime alcohol use disorders was found in group with higher scores of CTQ (X2 = 9.315, P = 0.009), emotional abuse (X2 = 8.025, P = 0.018), physical abuse (X2 = 20.4080, P < 0.001), but not in the group with higher scores of emotional neglect (X2 = 1.226, P = 0.542), sexual abuse (X2 = 2.779, P = 0.249), physical neglect (X2 = 3.978, P = 0.137), LTE-Q (X2 = 5.415, P = 0.067), and PSQI (X2 = 5.238, P = 0.073). Protective factor for alcohol abuse for men was identified to be heavy drinking (OR = 0.085, 95%CI: 0.011–0.661), and the risk factors for alcohol abuse were identified to be frequent drinking (OR = 2.736, 95%CI: 1.500, 4.988), and consumption of low liquor (OR = 2.563, 95%CI: 1.387, 4.734). Risk factors for alcohol dependence in males were identified to be consumption of low liquor (OR = 5.501, 95%CI: 2.004, 15.103), frequent drinking (OR = 2.680, 95%CI: 1.164, 6.170), and childhood physical abuse (OR = 2.310, 95% CI: 1.026, 5.201).ConclusionTraumatic experience during infant and prenatal periods does not have a strong statistical correlation with alcohol use disorders for male adults. However, subjects with high CTQ scores, experience of emotional abuse and physical abuse show a statistically higher prevalence of lifetime alcohol use disorders. Several risk factors including consumption of low liquor, frequent drinking, and childhood physical abuse contribute to alcohol dependence in male adults.

Alcohol use disorders in multidrug resistant tuberculosis (MDR-TB) patients and their non-tuberculosis family contacts in Nigeria.

Introductionthe main aim of this study was to determine the prevalence and associated factors of alcohol use disorder (AUD) in patients with Multi-Drug Treatment-Resistant Tuberculosis (MDR-TB) compared with their non-tuberculosis control, and its association with disease pattern and associated medical comorbidities.MethodsMDR-TB patients (128) and their respective caregivers were interviewed in a treatment unit in Nigeria. Diagnosis of AUD was made using the Structured Clinical Interview for DSM-IV Axis I Disorder, information was obtained on the severity of the TB and associated health problems.Resultsprevalence of AUD was (21.9%) and was significantly higher among cases than in controls (2.3%), p = 0.006. Severe TB, OR = 3.33 (1.56-6.83), hematological diseases, OR = 2.34 (1.06-4.33) and HIV/AIDS, OR = 3.01 (1.67-7.01) were the strongest predictors of AUD at 95% CI. Conclusion: AUD was highly prevalent in MDR-TB and was associated with certain medical comorbidities and increased severity of the illness.

Versorgung von Personen mit riskantem Alkoholkonsum und schwerer Alkoholkonsumstörung in Bremen: bedarfsgerecht und leitlinienkonform?

Early detection of risky alcohol use and severe alcohol use disorders (AUDs) is crucial to avoid adverse health consequences. The German "Guidelines on Screening, Diagnosis and Treatment of Alcohol Use Disorders" recommend to routinely screen patients for hazardous alcohol use and to subsequently conduct brief interventions, for example in primary healthcare. For severe AUDs, provision of withdrawal treatment is recommended in inpatient settings if complications are anticipated. To estimate the proportion of people with hazardous alcohol use or severe AUDs receiving healthcare as stipulated by the guidelines. The prevalence of hazardous use (female ≥12 g; male ≥24 g) and severe AUDs (female ≥60 g; male ≥90 g) was estimated using per capita consumption of pure alcohol. Treatment rates were estimated using survey data (for hazardous use) and inpatient admissions (for severe AUDs). All estimates refer to the adult population (15years or older) of the federal state of Bremen for 2016. Physicians screened 2.9% of all people with hazardous alcohol use and conducted brief interventions with 1.4%. Among people with severe AUDs, 7.1% received inpatient treatment. Among people with severe AUDs who required inpatient treatment, 14.1% received withdrawal treatment in inpatient settings. Treatment rates below average were registered among 21- to 39-year-olds. In Bremen, provision of guideline-conform healthcare for hazardous alcohol use and severe AUDs is insufficient, especially among 21- to 39-year-olds.

Documented brief intervention associated with reduced linkage to specialty addictions treatment in a national sample of VA patients with unhealthy alcohol use with and without alcohol use disorders.

Alcohol screening, brief intervention (BI) and referral to treatment is often considered stepped care, such that BI with referral links patients to treatment. A meta-analysis of randomized trials found no evidence that BI increases treatment for alcohol use disorder (AUD). This study aimed to determine whether BI is associated with receipt of treatment for AUD among patients receiving BI as part of routine care. Regression analysis. US Veterans Health Administration (VA), in which BI is supported by performance measurement and electronic clinical reminders. VA outpatients with positive Alcohol Use Disorders Identification Test Consumption screens (≥5) (n=830,825) documented nationally from 1 October 2009 to 30 May 2013. Regression models estimated the prevalence of receiving VA specialty addictions treatment within 0-365days for patients with documented BI (advice to reduce/abstain within 0-14days) compared to those without. Models clustered on patient and adjusted for demographics and mental health and substance use conditions were fit among all patients and stratified across documented past-year AUD diagnosis. Multiple secondary analyses assessed robustness of findings, including assessing repeated BI as a predictor. Among 830,825 VA outpatients with unhealthy alcohol use (1,172,606 positive screens), documented BI was associated with lower likelihood of receiving VA specialty addictions treatment [adjusted incidence rate ratio (aIRR)=0.84, 95% confidence interval (CI)=0.83-0.84]. Associations were similar for those with and without AUD (aIRR=0.83, 95% CI=0.82-0.84 and aIRR=0.86, 95% CI=0.83-0.88, respectively) and in most secondary analyses. However, among patients without AUD, documentation of more than one BI was associated with greater likelihood of treatment relative to no BI (aIRR=1.75, 95% CI=1.68-1.83). In a national sample of US Veterans Health Administration patients with unhealthy alcohol use, documented brief intervention for alcohol use was associated with lower likelihood of receiving specialty addictions treatment regardless of alcohol use disorder diagnosis.

Tailored interventions to support the implementation of the German national guideline on screening, diagnosis and treatment of alcohol-related disorders: a project protocol

Abstract. Background: The German Guideline on Screening, Diagnosis and Treatment of Alcohol Use Disorders aims to increase the uptake of evidence-based interventions for the early identification, diagnosis, prevention and treatment of alcohol-related disorders in relevant healthcare settings. To date, dissemination has not been accompanied by a guideline implementation strategy. The aim of this study is to develop tailored guideline implementation strategies and to field-test these in relevant medical and psycho-social settings in the city of Bremen, Germany. Methods: The study will conduct an impact and needs assessment of healthcare provision for alcohol use orders in Bremen, drawing on a range of secondary and primary data to: evaluate existing healthcare services; model the potential impact of improved care on public health outcomes; and identify potential barriers and facilitators to implementing evidence-based guidelines. Community advisory boards will be established for the selection of single-component or multi-faceted guideline implementation strategies. The tailoring approach considers guideline, provider and organizational factors shaping implementation. In field tests quality outcome indicators of the delivery of evidence-based interventions will be evaluated accompanied by a process evaluation to examine patient, provider and organizational factors. Outlook: This project will support the translation of guideline recommendations for the identification, prevention and treatment of AUD in routine practice and therefore contributes to the reduction of alcohol-related burden in Germany. The project is running since October 2017 and will provide its main outcomes by end of 2020. Project results will be published in scientific journals and presented at national and international conferences.

S.13.04 Interplay between inflammation and neuroplasticity in promoting antidepressant treatment

Alcohol consumption during adolescence might impede normal brain development, while more excessive drinking during this period poses a risk for developing alcohol use disorder. Here it was tested whether nucleus accumbens (NAcc) resting-state functional connectivity could be associated with lifetime drinking behavior in young adults, and whether it could predict their alcohol consumption during a one-year follow-up period. The current investigation was part of the bicentric Learning and Alcohol Dependence (LeAD) population-based prospective cohort study. One hundred and eighty-four 18-year-old male social drinking volunteers without a lifetime diagnosis of psychotic, bipolar, or alcohol use disorder were recruited from the general population. Seed-based resting-state functional connectivity was calculated for the bilateral NAcc in each participant. Across the group, the association between NAcc functional connectivity and lifetime alcohol consumption was assessed (p < .05, whole-brain FWE-corrected). Individual connectivity values were then extracted from regions that demonstrated a significant association to predict drinking behavior during a one-year follow-up period (n = 143), correcting for lifetime alcohol consumption. Weaker connectivity between the left NAcc and bilateral dorsolateral prefrontal cortex, inferior frontal gyrus, left caudate nucleus, left putamen, and left insula was associated with greater lifetime alcohol consumption, as well as with greater alcohol consumption during the one-year follow-up period. Our findings underscore the relevance of fronto-striatal connectivity to the field of alcohol research. Impaired prefrontal cognitive control might mediate excessive drinking behavior and may prove a promising biomarker for risk of future alcohol (ab)use.

The Association of Nicotine Replacement Therapy With Outcomes Among Smokers Hospitalized for a Major Surgical Procedure

There are concerns that starting nicotine replacement therapy (NRT) in the immediate perioperative period may negatively impact wound healing. We investigated the association of NRT with postoperative outcomes among smokers hospitalized for a surgical procedure. This was a retrospective study in 552 hospitals of active smokers hospitalized between January 1, 2015 and December 31, 2016 for a major surgical procedure (Medicare Severity Diagnosis-Related Group expected length of stay,≥ 2days). We analyzed the association of receipt of NRT within 2days of admission with a composite outcome of inpatient complications and with other outcomes. We developed a propensity score for receipt of NRT and examined differences in outcomes in a propensity-matched cohort. Of 147,506 active smokers, 25,651 (17.4%) were prescribed NRT within 2days of admission. Patients treated with NRT were younger; less likely to be black or Hispanic; more likely to have Medicaid; and more likely to have a diagnosis of alcohol or other substance use disorder, or COPD, compared with those who were not treated. In the propensity-matched analysis, there was no association between receipt of NRT and in-hospital complications (OR,0.99; 95%CI, 0.93-1.05), mortality (OR, 0.84; 95%CI, 0.68-1.04), all-cause 30-day readmissions (OR, 1.02; 95%CI, 0.97-1.07), or 30-day readmission for wound complications (OR, 0.96; 95%CI, 0.86-1.07). This is the first large observational study of surgical patients to demonstrate that perioperative NRT is not associated with adverse outcomes after surgery. These results strengthen the evidence that NRT should be prescribed routinely in the perioperative period.

Nucleus accumbens connectivity at rest is associated with alcohol consumption in young male adults

Alcohol consumption during adolescence might impede normal brain development, while more excessive drinking during this period poses a risk for developing alcohol use disorder. Here it was tested whether nucleus accumbens (NAcc) resting-state functional connectivity could be associated with lifetime drinking behavior in young adults, and whether it could predict their alcohol consumption during a one-year follow-up period.

Diagnosis and Management of Alcohol Use Disorder in Patients with Liver Disease: Lights and Shadows.

Alcohol use disorder is the most common cause of advanced liver disease in the Western world. Diagnosis of alcohol use disorder can be difficult because patients with liver disease tend to deny alcohol intake for the fear of being excluded from treatment and because available biomarkers of alcohol intake have poor specificity in these patients. Alcohol abstinence is the cornerstone of the therapy in these patients. However, pharmacological treatments for alcohol use disorders have not been formally tested in patients with advanced liver disease, except for baclofen. Psychosocial intervention became crucial in these patients considering the limited pharmacological choice. However, psychosocial approach and an appropriate team to manage these patients are not still well defined. In this review, we critically discuss the diagnosis and the management of alcohol use disorder in patients with liver disease.
