Acute alcohol consumption is associated with increased interatrial electromechanical delay in healthy men
Acute alcohol consumption can cause atrial fibrillation in patients with, and without, heart disease. Increased atrial electromechanical delay (EMD) has been associated with atrial fibrillation. We evaluated the atrial conduction properties by tissue Doppler imaging (TDI) echocardiography in healthy men following acute alcohol intake.
Thirty healthy male volunteers were included in this study. Baseline ECG, heart rate, blood pressure, and TDI echocardiographic findings were compared to readings take one hour after drinking six 12-oz cans of beer (76.8 g of ethanol).
Although the blood pressure and heart rate remained similar before and one hour after alcohol intake, Pmax and Pd values were significantly prolonged (114.2 ± 10.4 vs 100.8 ±
± 10.6, p = 0.002; 50.6 ± 9.6 vs 34.5 ± 8.8, p < 0.0001). Interatrial EMD was significantly
increased after drinking alcohol compared to the baseline (19.8 ± 9.2 vs 14.0 ± 5.5 ms, p < 0.0002).
Acute moderate alcohol intake was associated with an increased interatrial EMD obtained by TDI echocardiography. This finding may help explain how these patients express increased susceptibility to atrial fibrillation.

Different guidelines for different countries? On the scientific basis of low-risk drinking guidelines and their implications
The scientific evidence for low-risk drinking guidelines was examined in a narrative review focusing on three points: definition of exposure, the best way to select outcomes and risk relations and how to determine thresholds.
With respect to exposure, at least two dimensions should be incorporated: average volume of alcohol consumption and patterns of irregular heavy drinking occasions.
Mortality should be selected as the most severe outcome, and a disaggregated approach should be adopted incorporating the regional demographic and cause of death structure.
Finally, our plea is for establishing a general threshold for acceptable risk on a societal level rather than ad hoc specific committees setting norms for specific risks. Acceptable thresholds will be different if the risk is to oneself or to others.

News Release - "Hazardous" drinking in minor injuries unit similar to that of emergency care
Hazardous drinking among patients attending a minor injuries unit: a pilot study
Excessive alcohol consumption increases the likelihood of accidental injury. This pilot study reports on the prevalence of hazardous drinkers presenting to a minor injuries unit. The proportion of hazardous drinkers is broadly similar to that found in emergency departments, suggesting that such units could also host alcohol intervention and brief advice activities.

SAMHSA’s Definition and Guiding Principles of Recovery – Answering the Call for Feedback
As part of SAMHSA’s efforts to provide stakeholders the opportunity to comment on the working definition of recovery and related guiding principles, several public feedback forums were run during the period August 12- 26, 2011. In addition to the forums, feedback was also submitted via the comments on the Recovery Defined – Give Us Your Feedback blog post.
The response to our request for feedback was tremendous and clearly demonstrated the field’s interest and concern on this important issue. The blog post received 259 comments. The two forums combined had over 1,000 participants, nearly 500 ideas, and over 1,200 comments on the ideas. Over 8,500 votes were also cast in support of the ideas on the forums.
SAMHSA appreciates the many thoughtful responses and suggestions received. All ideas were given careful consideration, and suggestions were incorporated into the final definition and principles (see below). Of particular note, we have added a preamble to the definition and principles emphasizing that there are many different pathways to recovery, and we have highlighted the importance of hope as the catalyst to the recovery process.
SAMHSA will disseminate the definition and principles as a resource to policy-makers, systems administrators, providers, practitioners, consumers, peers, family members, advocates, and others. The definition and principles are intended to help with the design, measurement, and reimbursement of services and supports to meet the individualized needs of those with mental disorders and substance use disorders. > > > > Read More
Acquisition, expression, and reinstatement of ethanol-induced conditioned place preference in mice: effects of exposure to stress and modulation by me
Nicotinic acetylcholine receptors mediate some of the rewarding and motivational effects of ethanol, including relapses. Relapses are common in drug addicts during abstinence when exposure to any stressor ensues.
However, the role of nicotinic acetylcholine receptors in the ethanol- and stress-induced reinstatement of ethanol-induced conditioned place preference has not yet been explored. Therefore, the present study investigated the influence of mecamylamine, a nicotinic acetylcholine receptors antagonist on acquisition, expression, and reinstatement of ethanol-induced conditioned place preference in adult male Swiss mice.
The results revealed that mecamylamine (0.1–10 µg/mouse, intracerebroventricularly) dose dependently prevented the development, expression, and reinstatement of ethanol-induced conditioned place preference.
Further, acute treatment with mecamylamine blocked the restraint stress and forced swim stress-induced reinstatement of ethanol-induced conditioned place preference.
All of these treatments had no influence on the locomotor activity. Therefore, it is concluded that mecamylamine blocks the acquisition, expression and reinstatement of conditioned reinforcing effects of ethanol without per se reinforcing or aversive influence.
This ability of mecamylamine might be a potential advantage in the treatment of alcoholism.

Interrelationship of substance use and psychological distress over the life course among a cohort of urban African Americans
Substance use and psychological problems are major public health issues because of their high prevalence, co-occurrence, clustering in socio-economically disadvantaged groups, and serious consequences. However, their interrelationship over time is not well understood.
This study identifies and compares the developmental epidemiology from age 6 to 42 of substance use and psychological distress in a population of African American men and women. Data come from the Woodlawn study, a longitudinal study of an urban community cohort followed since 1966. We use structural equation modeling to examine pathways between substance use (i.e., alcohol, marijuana, and cocaine) and psychological distress over time by gender.
We find significant continuity from adolescence to midlife for substance use and for psychological distress, as well as significant correlations within time periods between substance use and psychological distress, particularly among women. We also find greater adolescent substance use predicts psychological distress in young adulthood for men, but no cross-lag associations for women. Women's adolescent psychological distress and substance use are linked uniquely to that of their mothers. Findings show additional gender differences in the developmental etiology of substance use and psychological distress.
Findings demonstrate the continuity of substance use and psychological distress over time; the contemporaneous relationships between psychological distress and substance use within time periods, and minimal cross-lagged relationships. Findings also show that adolescent substance use may set boys on a pathway of long-term psychological distress, thus adding to evidence of negative consequences of frequent use.

Alcohol-Only Admissions Comprised 23% of Treatment Admissions in 2009; Nearly 40% of Admissions Were for Drugs Other Than Alcohol
The percentage of substance abuse treatment admissions for drug-only problems has risen since 1992 while the percentage for alcohol-only and the co-abuse of alcohol and drugs has declined, according to the most recent data from the Treatment Episode Data Set (TEDS).
The percentage of drug-only treatment admissions increased from 20% in 1992 to 38% in 2009 (the most current year for which data are available). Alcohol-only treatment admissions, which had surpassed drug-only admissions prior to 1999, decreased from 37% to 23% over the same period. The percentage of treatment admissions for the co-abuse of alcohol and other drugs also decreased, from a high of 44% in 1997 to 37% in 2009.
While these findings may reflect actual changes in substance abuse and dependence, they may also be the result of other factors, such as changes in insurance policies or access to treatment.

Critique 065: Are there differences in mortality between people consuming wine and those consuming other types of alcoholic beverages? — 20 December 2
Holahan CJ, Schutte KK, Brennan PL, North RJ, Holahah CK, Moos BS, Moos RH. Wine consumption and 20-year mortality among late-life moderate drinkers. J Stud Alcohol Drug 2012; 73: 80–88.
Background: There are consistent data showing that moderate consumers of alcohol have lower risk of cardiovascular disease and many other diseases of ageing, as well as lower risk of mortality, than do abstainers.1,2 Experimental data in animals and humans have defined a large number of mechanisms for such an effect.3 There is still some inconsistency as to differential effects according to the type of beverage consumed. In most epidemiologic studies, wine consumers have been shown to have higher levels of education and income, to consume a healthier diet, and have other characteristics that are associated with better health outcomes than consumers of other beverages.4,5 A recent meta-analysis by Constanzo et al6 showed that moderate consumers of both wine and beer had lower risk of cardiovascular disease than did people who generally consumed spirits.
Experimental data clearly show that polyphenols and other constituents in wine, in addition to the alcohol, have beneficial effects on cardiovascular risk in animals, including humans.3, 7-9 The question is whether epidemiologic studies comparing people who consume certain beverages (rather than comparing the beverages themselves) demonstrate such differences in terms of health effects.
A Forum reviewer points out that studies often show that “it is the type of alcoholic beverage which is consumed most frequently in a population which exerts the clearest protective effect. For example, in France it is moderate wine consumption and in Germany moderate beer consumption associated with the healthiest outcomes.10-11 Wine consumers in a customary non-wine drinking country like Denmark may be especially different from the general population. Hence, attempting to adjust for the potential confounding by other lifestyle factors is an ongoing challenge for epidemiologists who are seeking to determine if the consumption of one type of beverage containing alcohol has different effects on health from the consumption of other types of beverage.” > > > > Read More

Positive Alcohol Expectancies Mediate the Influence of the Behavioral Activation System on Alcohol Use: A Prospective Path Analysis
Gray's (1975, 1987) behavioral activation (BAS) and behavioral inhibition systems (BIS) are thought to underlie sensitivity to reinforcement and punishment, respectively.
Consistent with Gray's theory and the Acquired Preparedness model, BAS may facilitate the learning of positive alcohol expectancies (PAEs) over time, leading to increases in drinking. Yet, no prospective tests of this pathway have been reported.
The present study investigated whether BAS prospectively predicted PAEs and whether PAEs mediated the association between BAS and subsequent alcohol use. We hypothesized that BAS would influence drinking specifically via enhancement-related PAEs. We also explored the role of BIS in PAEs and drinking.
College students (N = 557) completed online BAS, PAE, and alcohol use measures in September of their first (T1), second (T2), and third (T3) years of college. We conducted autoregressive path analyses with three BAS subscales and BIS (T1) as predictors, four PAE types (T2) as mediators, and quantity and frequency of drinking (T3) as outcomes.
The BAS Fun-Seeking scale was prospectively associated with PAEs, and there was a significant indirect path from Fun-Seeking to alcohol use mediated specifically through activity enhancement PAEs. BIS was positively associated with some PAE types, but did not have indirect effects on drinking.
Findings are consistent with both the theory of the BAS and the Acquired Preparedness model, as individuals high on BAS Fun-Seeking may find the rewarding properties of alcohol more reinforcing, leading to stronger enhancement PAEs and increased drinking over time.
The prospective design helps establish the temporal association between BAS and alcohol-related learning, and points to the need for prevention efforts that target these at-risk students.

Failure to Consider Future Consequences Increases the Effects of Alcohol on Aggression
The failure to consider the future consequences of one's behavior is a major risk factor for aggression. Aggressive people tend to act first, and think later.
Some people focus on the “here and now” rather than on the future, a tendency measured by the Consideration of Future Consequences (CFC) scale (Strathman, Gleicher, Boninger, & Edwards, 1994).
Alcohol intoxication is a neuro-biological variable that produces similar effects. Participants in the present experiment completed the CFC scale and then consumed either an alcohol or a placebo beverage. Next, they competed against a same-sex ostensible partner on an interpersonally adversarial competitive task in which the winner could administer electric shocks to the loser (the aggression measure).
As expected, aggression was highest in intoxicated persons with low CFC scores.
Being unconcerned about the future consequences of one's actions, in conjunction with acute alcohol intoxication, combine in a pernicious manner to increase aggression.

Youth Exposure to Alcohol Product Advertising on Local Radio in 75 U.S. Markets, 2009
Alcohol is the number one drug problem among youth, causing 4,600 deaths among persons under 21 every year. At least 13 longitudinal studies have found a strong association between youth exposure to alcohol marketing and underage drinking. The alcohol industry observes a voluntary 30 percent limit on the size of the underage audience for its advertising. The National Research Council and Institute of Medicine, 24 state attorneys general and the Federal Trade Commission have all encouraged the industry to adopt a more restrictive standard.
Radio continues to be a vibrant medium among youth, despite the proliferation and innovation of digital media. For this report, the Center on Alcohol Marketing and Youth (CAMY) at the Johns Hopkins Bloomberg School of Public Health analyzed alcohol advertisements placed on radio in the 75 local markets in the United States in 2009 for which full-year data from a consistent survey methodology were available. These markets represent approximately 46.5 percent of the U.S. population age 12 and above.
Key findings from the report include:
- Approximately 9 percent of all alcohol product advertisements aired on programming with underage audiences in violation of the industry's 30 percent standard. These advertisements generated 18 percent of youth exposure to alcohol advertising.
- Three brands (Bud Light, Coors Light, and Miller Lite) placed close to half of the noncompliant ads.
- Close to one-third (32%) of advertising placements occurred when proportionately more youth were listening than adults age 21 and above.
- These overexposing ads generated more than half of youth exposure to radio advertising for alcohol in 2009.
- In the majority of markets measured by Arbitron's new Portable People Meter™ technology in 2009, girls ages 12 to 20 were more likely than boys in the same age group to be exposed to alcohol advertising for alcopops, distilled spirits, and wine.
The alcohol industry's current standard covers all people below the age of 21; however, more than two-thirds of underage exposure to alcohol advertising on the radio went to young people between the ages of 12 and 20. Protecting this age group, which is less than 15 percent of the population, from undue exposure to alcohol advertising is the reason why the National Research Council and Institute of Medicine and 24 state attorneys general have called for the industry to adopt a new standard limiting alcohol advertising to programming where they are less than 15 percent of the audience.
In summary, this report finds that alcohol advertisers frequently violate a relatively weak voluntary standard, resulting in substantial undue youth exposure and overexposure to alcohol advertising.
NLM Director's Comments Transcript Alcohol & Breast Cancer Risk: 12/07/2011
Greetings from the National Library of Medicine and MedlinePlus.gov
Regards to all our listeners!
I'm Rob Logan, Ph.D. senior staff National Library of Medicine for Donald Lindberg, M.D, the Director of the U.S. National Library of Medicine.
Low levels of alcohol consumption (or about three drinks a week) were associated with a significantly increased risk of breast cancer – in findings derived from a larger study of nurses recently published in the Journal of the American Medical Association.
The study of about 106,000 U.S. nurses found women who self-reported drinking the equivalent of three to six glasses of wine each week were 15 percent more likely to develop breast cancer than women who never or rarely drank alcohol. The differences between the groups were moderate but statistically significant.
Moreover, the study found the participants who reported they drank the equivalent of two glasses of wine a day over time were 51 percent more likely to develop breast cancer than women who never or rarely drank. Hence, the study suggests higher drinking levels significantly increases the risk of developing breast cancer.
The study also found an increased risk of breast cancer was more linked to cumulative drinking over time rather than what type of alcohol participants drank, or the age when a woman begins to consume wine, spirits, or beer. > > > > Read More
