21st Century Cures Initiative
Led by Rep. Fred Upton, Chairman of the House Energy and Commerce Committee, the goal of this initiative is to enhance and accelerate the discovery, development, and delivery of new treatments and cures. On July 10, 2015, the House passed the bill, which designated $8.75 billion for NIH and $550 million for the U.S. Food and Drug Administration (FDA) over five years. A Senate version of the bill is yet to be released.
Joint Review of Training Grants
To functionally integrate Institutional National Research Service Award Research Training at NIAAA and the National Institute on Drug Abuse (NIDA), a single special emphasis panel will be set up each year to review germane applications received by the two ICs in response to the parent notice of funding opportunities (NOFOs) (PAR-14-015 (T32) and PA-14-016 (T35)). The panels will be jointly managed by staff from NIAAA and NIDA to ensure that appropriate expertise is involved to review the breadth of research training proposed in the applications. The first set of applications to be reviewed in this manner will be those submitted for the May 25, 2016, (non-AIDS) and September 7, 2016, (AIDS) receipt dates.
A major focus of CRAN from September-January has been the start-up of the longitudinal Adolescent Brain Cognitive Development Study (ABCD). The ABCD Study is the largest long-term study of cognitive and brain development in children across the United States to date. The project will recruit 10,000 healthy children ages 9 to 10, before they initiate alcohol or other drug use, and follow them through the period of highest risk for substance use and other mental health disorders (ten years). Scientists will track exposure to substances (including nicotine, alcohol, and marijuana), academic achievement, cognitive skills, mental health, and brain structure and function using state of the art research methods. Awards were made to the coordinating Center (University of California, San Diego, (UCSD)), Data Analysis and Informatics Center (UCSD), and 11 sites across the United States. In addition, NIH staff collaborators, Drs. Antonio Noronha and John Matochik (NIAAA), and Dr. Kevin Conway (NIDA) were named, and a project manager, Dr. Gaya Dowling, was hired. An operations group consisting of Drs. Susan Weiss and Gaya Dowling from NIDA, Dr. Peggy Murray from NIAAA, Drs. Terry Jernigan, Sandra Brown, and Susan Tapert from the UCSD Coordinating Center, and Drs. Hugh Garavan and Anders Dale from the UCSD Data Analytics and Informatics Center, as well as a Steering Committee made up of study leaders and NIH collaborators, has been formed to lead and coordinate the collaboration.
The first meeting of ABCD investigators and NIH staff collaborators took place in Chicago, Illinois, on October 22–23, 2015, in conjunction with the Society for Neuroscience (SfN) annual meeting. Given the large, multisite structure of the project, a number of standing committees, advisory groups (such as a Community Advisory Council), and working groups made up of study site staff, outside experts, and NIH subject area experts have been formed and begun meeting to work on issues related to study start-up and implementation. These issues include such areas as bioethics and medical oversight, study design and biostatistics, substance use assessment, neurocognition assessment, brain image acquisition and analysis, mobile technologies for assessment, informatics, culture and environment, and resource sharing and publication. The External Advisory Board, chaired by Dr. Michael Charness, has been named and had their first teleconference with ABCD leadership in December 2015 and first face to face meeting January 14–15, 2016. Protocols are being developed and pilot-tested, and are expected to be ready for initial recruitment efforts at schools in the summer of 2016, with full-blown recruitment at all sites by fall 2016.
Other CRAN activities include the development of a strategic plan which describes the nature of collaborative research and topic areas of joint priority for NIAAA, NIDA, and the National Cancer Institute (NCI). As the plan is developed, attention is being paid to how it fits into the updated strategic plans of NIAAA, NIDA, and NCI.
Notice of Funding Opportunities (NOFOs)
Workgroups are being formed with membership from NIAAA, NIDA, and NCI to develop NOFOs in areas such as health services research; bi-directional basic to clinical to epidemiological translational studies of polysubstance use and abuse; and target assessment, engagement and data replicability to improve substance use disorders treatment outcomes.

Dr. Kenneth R. Warren retired in October 2015 after 41 years of federal service, 39 of them at NIAAA. Following his graduate and postdoctoral training in biochemistry, Dr. Warren joined the Walter Reed Army Institute for Research where he focused on metabolic control mechanisms, including birth defects involving metabolic problems. In 1976, Dr. Warren joined NIAAA, where he turned his attention to seminal reports about a newly-described condition known as fetal alcohol syndrome (FAS). Recognizing its public health ramifications, Dr. Warren pioneered NIAAA’s support for FAS research. Dr. Warren’s early passion for FAS studies yielded groundbreaking results. In 1977, he authored the first U.S. Government health advisory on alcohol and pregnancy, and in 1981 he was the chief architect of the Surgeon General’s Advisory on Alcohol Use in Pregnancy—the advisory that brought about the now-familiar warning labels on alcoholic beverage containers. In recognition of his critical role, Dr. Warren received the Public Health Service’s Superior Service Award in 1982. He also helped to develop the updated advisory issued in 2005.
During his NIAAA career, Dr. Warren held many leadership roles, first as Branch Chief and then Deputy Director of the former Division of Extramural Research. Later he was Director of the Office of Scientific Affairs as well as Executive Secretary of the Institute’s National Advisory Council. Most recently, he was NIAAA Deputy Director for 7 years. He also served as NIAAA Acting Director for more than 5 years. During that time, Dr. Warren was instrumental in guiding NIAAA during the launch of a major NIH initiative: the Collaborative Research on Addiction at NIH, or CRAN. Dr. Warren received the NIH Director’s Award in 2014 for “outstanding and sustained service to the National Institutes of Health and commitment to alcohol and addictions research.” Dr. Warren has also received numerous honors from the wider alcohol research community including the 1996 Seixas Award from the Research Society on Alcoholism (RSA) and the 2002 Henry Rosett Award from RSA’s Fetal Alcohol Syndrome Study Group. In 2007, the National Organization on Fetal Alcohol Syndrome (NOFAS) inducted Dr. Warren into its Tom and Linda Daschle FASD Hall of Fame, and in 2008 he received the NOFAS Excellence Award. In 2014, Dr. Warren was honored with the RSA Lifetime Achievement Award.

NOFOs issued by NIAAA between September 17, 2015 and January 28, 2016:
Integrative Neuroscience Initiative on Alcoholism (INIA) Consortia (RFA-AA-16-004 Collaborative U01, RFA-AA-16-005 Research Resource U24, RFA-AA-16-006 Administrative Core U24) The purpose of this NOFO is to solicit cooperative agreement applications that are integrated, multidisciplinary, and collaborative, investigating the neuronal mechanisms of excessive alcohol intake with a focus on immune signaling and stress. More specifically, one focus of the initiative will be to examine brain immune signaling mechanisms promoting and controlling excessive alcohol consumption. A second focus will be to examine enduring consequences of stress challenges on adaptations in brain circuitry leading to excessive drinking and to altered stress responsiveness. An additional emphasis to be promoted within this initiative is the identification of drugable genomic targets to lay the foundations for new treatments for alcohol dependence. As in prior years, projects supported under this initiative are expected to integrate approaches at the molecular, cellular, synaptic, physiological, and behavioral level of analysis. Integration will be promoted by supporting two consortia, each comprising an administrative core (RFA-AA-16-006 U24), multiple component projects (RFA-AA-16-004 U01), and relevant scientific resource (RFA-AA-16-005 U24) cores as needed.
Multi-Site Randomized Controlled Clinical Trial Research Center on Alcohol's Health Effects (U10) (PAR-16-363) This NOFO invites Cooperative Agreement (U10) applications for implementation of investigator-initiated randomized controlled clinical trials on alcohol’s effects on neurological diseases, most especially stroke, and the health issues that are associated with aging. Applicants for the U10 Clinical Trial Implementation Cooperative Agreement must be able to begin the trial without further planning activities when the U10 is awarded. Therefore, investigators who have already completed planning activities through an NIAAA-funded U34 clinical trial planning grant are expected to apply. The randomized controlled clinical trials are expected to be hypothesis-driven, milestone-defined, related to the research missions of both NIAAA and NINDS, and considered high priority by the participating Institutes.
Limited Competition for the Continuation of CoFASP (Collaboration on Fetal Alcohol Spectrum Disorders Prevalence) Diagnostic Classifications (Collaborative U01) (RFA-AA-16-007). This limited-competition NOFO invites a cooperative agreement (U01) application from projects funded within the Collaboration on Fetal Alcohol Spectrum Disorders [FASD] Prevalence (CoFASP). The purpose of this limited competition is to allow additional follow-up for the development and use of a standardized diagnostic system to evaluate and report clinical characteristics of FASD among affected children and establish prevalence rates.

The meeting is funded by an R13 conference grant from NIAAA (Dr. John Matochik, DNB, is the Program Officer).
Significance: This paper identifies a novel gene, Ras suppressor 1 (Rsu1), which underlies vulnerability to AUD. The authors use a well-established Drosophila model to determine that Rsu1 is important for alcohol-related behaviors such as alcohol sensitivity and alcohol preference. The most important aspect of this study is the finding that polymorphisms in Rsu1 identified in human adolescents is associated with alterations in brain activation during reward anticipation. In addition, an independent sample of subjects with AUD showed a genetic association with a potential rare variant in Rsu1. This study is a key example of how to advance the identification of genes underlying AUD by using a translational approach.
Alcohol abuse is highly prevalent, but little is understood about the molecular causes. Here, we report that Ras suppressor 1 (Rsu1) affects ethanol consumption in flies and humans. Drosophila lacking Rsu1 show reduced sensitivity to ethanol-induced sedation. We show that Rsu1 is required in the adult nervous system for normal sensitivity and that it acts downstream of the integrin cell adhesion molecule and upstream of the Ras-related C3 botulinum toxin substrate 1 (Rac1) GTPase to regulate the actin cytoskeleton. In an ethanol preference assay, global loss of Rsu1 causes high naïve preference. In contrast, flies lacking Rsu1 only in the mushroom bodies of the brain show normal naïve preference but then fail to acquire ethanol preference like normal flies. Rsu1 is, thus, required in distinct neurons to modulate naïve and acquired ethanol preference. In humans, we find that polymorphisms in RSU1 are associated with brain activation in the ventral striatum during reward anticipation in adolescents and alcohol consumption in both adolescents and adults. Together, these data suggest a conserved role for integrin/Rsu1/Rac1/actin signaling in modulating reward-related phenotypes, including ethanol consumption, across phyla. (Ojelade SA et al.

Significance: Increasing evidence supports the role of appetite-regulating pathways in addictions. This study provides evidence of a ghrelin-leptin cross-talk in individuals with AUD and suggests that the relationship between ghrelin and leptin may play a role in alcohol craving. These results hold important clinical value because cue-induced craving may be associated with relapse and may predict alcohol-related outcomes. In addition, while studies have tended to focus on the role of individual appetite-regulating peptides in alcohol consumption, this study paves the way for future translational research on the role of interactions between these peptides in alcohol consumption.
Increasing evidence supports the role of appetite-regulating pathways, including ghrelin and leptin, in alcoholism. This study tested the hypothesis that intravenous (IV) exogenous ghrelin administration acutely decreases endogenous serum leptin levels, and that changes in leptin levels negatively correlate with alcohol craving. This was a double-blind, placebo-controlled human laboratory study. Non-treatment-seeking, alcohol-dependent, heavy-drinkers (n = 45) were randomized to receive IV ghrelin or placebo, followed by a cue reactivity procedure, during which participants were exposed to neutral (juice) and alcohol trial cues. There was a main effect for IV ghrelin administration, compared to placebo, in reducing serum leptin levels [p <.05]. Post hoc analysis showed significant differences in serum leptin levels at the alcohol trial [p <.05] that persisted at the end of the experiment [p <.05]. By contrast, there were no significant differences in serum leptin levels at the juice trial [p = n.s.]. The change of serum leptin level at the alcohol trial correlated with the increase in alcohol urge [p <.05], while urge to drink juice was not correlated with the leptin change at the juice trial [p = n.s.]. These findings provide preliminary evidence of ghrelin – leptin cross-talk in alcoholic individuals and suggest that their relationship may play a role in alcohol craving. (Haass-Koffler CL et al. Transl Psychiatry 2015;5: e646)
Significance: It has long been acknowledged that the acute physiological withdrawal symptoms contribute indirectly, if at all, to the motivation to drink alcohol; preventing or diminishing acute withdrawal is not sufficient to prevent relapse. Instead the post-withdrawal period—characterized by anxiety and negative affect, sleep disturbances, anhedonia, and dysphoria—is associated with heightened vulnerability to relapse and elevated drinking. This study reveals the selective involvement of the kappa-opioid receptor in the motivational post-withdrawal syndrome and not the acute physiological syndrome and lends support to its potential value as a medication target.
Chronic intermittent alcohol vapor exposure leads to increased dynorphin (DYN) A-like peptide expression and heightened kappa-opioid receptor (KOR) signaling in the central nucleus of the amygdala (CeA) and these neuroadaptive responses differentiate alcohol-dependent from non-dependent phenotypes. Important for therapeutic development efforts is understanding the nature of the stimulus that drives dependence-like phenotypes such as escalated alcohol self-administration. Accordingly, the present study examined the impact of intra-CeA KOR antagonism on escalated operant alcohol self-administration and physiological withdrawal symptoms during acute withdrawal and protracted abstinence in rats previously exposed to chronic intermittent alcohol vapor. Following operant training, rats were implanted with intra-CeA guide cannula and exposed to long-term intermittent alcohol vapor exposure that resulted in escalated alcohol self-administration and elevated physiological withdrawal signs during acute withdrawal. Animals received intra-CeA infusions of the KOR antagonist nor-binaltorphimine (nor-BNI; 0, 2, 4, or 6 μg) prior to operant alcohol self-administration sessions and physiological withdrawal assessment during acute withdrawal and protracted abstinence. The results indicated that site-specific KOR antagonism in the CeA ameliorated escalated alcohol self-administration during both acute withdrawal and protracted abstinence test sessions, whereas KOR antagonism had no effect on physiological withdrawal scores at either time point. These results dissociate escalated alcohol self-administration from physiological withdrawal symptoms in relation to KOR signaling in the CeA and help clarify the nature of the stimulus that drives escalated alcohol self-administration during acute withdrawal and protracted abstinence.

Significance: Persons with AUD have a far greater incidence of pneumonia than the general population. This study investigates alcohol’s modification of alveolar epithelial cells and the resulting change in the inflammatory state of the airways as a mechanism by which alcohol consumption disturbs pulmonary lines of defense. Using samples obtained from well-characterized human subjects, the authors report that toll-like receptor (TLR) 2 is up-regulated and TLR4 decreased in AUD subjects, compared to nonsmoking/non-AUD subjects, and correlated with their scores on the Alcohol Use Disorders Identification Test. Interleukin (IL)-6 and IL-8 were also increased in bronchial washings from AUD subjects. The combination increases susceptibility to Streptococcus pneumoniae infection.
BACKGROUND: The lung has a highly regulated system of innate immunity to protect itself from inhaled microbes and toxins. The first line of defense is mucociliary clearance, but if invaders overcome this, inflammatory pathways are activated. Toll-like receptors (TLRs) are expressed on the airway epithelium. Their signaling initiates the inflammatory cascade and leads to production of inflammatory cytokines such as interleukin (IL)-6 and IL-8. We hypothesized that airway epithelial insults, including heavy alcohol intake or smoking, would alter the expression of TLRs on the airway epithelium. METHODS: Bronchoscopy with bronchoalveolar lavage and brushings of the airway epithelium was performed in otherwise healthy subjects who had normal chest radiographs and spirometry. A history of alcohol use disorders (AUDs) was ascertained using the Alcohol Use Disorders Identification Test (AUDIT), and a history of cigarette smoking was also obtained. Age, gender, and nutritional status in all groups were similar. We used real-time polymerase chain reaction (PCR) to quantitate TLR1 to 9 and enzyme-linked immune assay to measure tumor necrosis factor-α, IL-6, and IL-8. RESULTS: Airway brushings were obtained from 26 nonsmoking/non-AUD subjects, 28 smoking/non-AUD subjects, 36 smoking/AUD subjects, and 17 nonsmoking/AUD subjects. We found that TLR2 is up-regulated in AUD subjects, compared to nonsmoking/non-AUD subjects, and correlated with their AUDIT scores. We also measured a decrease in TLR4 expression in AUD subjects that correlated with AUDIT score. IL-6 and IL-8 were also increased in bronchial washings from AUD subjects. CONCLUSIONS: We have previously demonstrated in normal human bronchial epithelial cells that in vitro alcohol exposure up-regulates TLR2 through a NO/cGMP/PKG-dependent pathway, resulting in up-regulation of inflammatory cytokine production after Gram-positive bacterial product stimulation. Our current translational study confirms that TLR2 is also up-regulated in humans with AUDs. (Bailey KL et al. Alcohol Clin Exp Res 2015 Sep;39:1691-7)
Significance: Obesity and alcohol consumption often coexist and work synergistically to promote steatohepatitis; however, the underlying mechanisms remain obscure. This study demonstrates that feeding mice a high-fat diet combined with acute ethanol consumption synergistically induces acute liver inflammation and injury through the elevation of hepatic or serum free fatty acids and subsequent up-regulation of hepatic CXCL1 expression and promotion of hepatic neutrophil infiltration.
Obesity and alcohol consumption often coexist and work synergistically to promote steatohepatitis; however, the underlying mechanisms remain obscure. Here, we demonstrate that feeding mice a high-fat diet (HFD) for as little as 3 days markedly exacerbated acute ethanol binge–induced liver neutrophil infiltration and injury. Feeding mice with an HFD for 3 months plus a single binge of ethanol induced much more severe steatohepatitis. Moreover, 3-day or 3-month HFD-plus-ethanol binge (3d-HFD+ethanol or 3m-HFD+ethanol) treatment markedly up-regulated the hepatic expression of several chemokines, including chemokine (C-X-C motif) ligand 1 (Cxcl1), which showed the highest fold (approximately 20-fold and 35-fold, respectively) induction. Serum CXCL1 protein levels were also markedly elevated after the HFD+ethanol treatment. Blockade of CXCL1 with a CXCL1 neutralizing antibody or genetic deletion of the Cxcl1 gene reduced the HFD+ethanol-induced hepatic neutrophil infiltration and injury, whereas overexpression of Cxcl1 exacerbated steatohepatitis in HFD-fed mice. Furthermore, expression of Cxcl1 messenger RNA was up-regulated in hepatocytes, hepatic stellate cells, and endothelial cells isolated from HFD+ethanol-fed mice compared to mice that were only given the HFD, with the highest fold induction observed in hepatocytes. In vitro stimulation of hepatocytes with palmitic acid up-regulated the expression of Cxcl1 messenger RNA, and this up-regulation was attenuated after treatment with an inhibitor of extracellular signal–regulated kinase 1/2, c-Jun N-terminal kinase, or nuclear factor κB. In addition, hepatic or serum levels of free fatty acids were higher in HFD+ethanol-fed mice than in the control groups. Conclusion: An HFD combined with acute ethanol consumption synergistically induces acute liver inflammation and injury through the elevation of hepatic or serum free fatty acids and subsequent up-regulation of hepatic CXCL1 expression and promotion of hepatic neutrophil infiltration.

Significance: Alcohol use may accelerate HIV disease progression, but the plausible biological mechanisms have not been clearly elucidated. Unhealthy alcohol use was independently associated with a marker of monocyte activation (i.e., higher sCD14) that predicts mortality in treated HIV-infected individuals. Longitudinal research should examine whether unhealthy alcohol use predicts changes in sCD14 prior to and following antiretroviral therapy initiation.
BACKGROUND: Alcohol use may accelerate HIV disease progression, but the plausible biological mechanisms have not been clearly elucidated. METHODS: HIV-positive persons who were not on antiretroviral therapy (ART) completed the baseline assessment for a longitudinal study examining the association of alcohol use with HIV disease markers. Oversampling drinkers, baseline samples were tested for markers of monocyte activation (soluble CD14 [sCD14]), inflammation (interleukin-6 [IL-6]-6), and coagulation (d-dimer). We defined "unhealthy alcohol use" as testing positive using the Alcohol Use Disorders Identification Test-Consumption (≥3 for women and ≥4 for men) in the past 3 months or testing positive using a biomarker of heavy drinking, phosphatidylethanol (≥50 ng/ml). Multiple linear regression was used to examine the associations of unhealthy alcohol use with sCD14, log10 IL-6, and d-dimer. RESULTS: Compared to those who were abstinent from alcohol, unhealthy drinkers had significantly higher sCD14 levels (mean = 1,676 vs. 1,387 ng/ml; mean difference [95% confidence interval (CI)] = 289 [83, 495], p < 0.01). In analyses adjusted for demographic factors, current cigarette smoking, and HIV disease markers, unhealthy drinkers continued to display significantly higher sCD14 levels compared to those who were abstinent from alcohol (adjusted mean = 1,670 vs. 1,406 ng/ml; adjusted mean difference [95% CI] = 264 [47, 480], p = 0.02). Unhealthy alcohol use was not significantly associated with IL-6 or d-dimer levels. CONCLUSIONS: Unhealthy alcohol use was independently associated with a marker of monocyte activation (i.e., higher sCD14) that predicts mortality in treated HIV infection. Longitudinal research should examine whether unhealthy alcohol use predicts changes in sCD14 prior to and following ART initiation. (Carrico AW et al. Alcohol Clin Exp Res 2015 Dec;39(12):2422-6)
Significance: Physical pain and negative affect have been described as risk factors for alcohol use following alcohol treatment. This study, a secondary analysis of two clinical trials for AUD examined the associations between pain, negative affect, and AUD treatment outcomes. Pain scores were associated with drinking outcomes in both datasets. Pain scores were also positively associated with negative affect, and negative affect mediated the association between pain and drinking outcomes. Social behavior network therapy attenuated the association between pain and drinking.
OBJECTIVE: Physical pain and negative affect have been described as risk factors for alcohol use following alcohol treatment. The current study was a secondary analysis of 2 clinical trials for alcohol use disorder (AUD) to examine the associations between pain, negative affect and AUD treatment outcomes. METHOD: Participants included 1,383 individuals from the COMBINE Study (COMBINE Pharmacotherapies and Behavioral Interventions for Alcohol Dependence; COMBINE Study Research Group, 2003; 31% female, 23% ethnic minorities, average age = 44.4 [SD = 10.2]), a multisite combination pharmacotherapy and behavioral intervention study for AUD in the United States, and 742 individuals from the United Kingdom Alcohol Treatment Trial (UKATT Research Team, 2001; 25.9% female, 4.4% ethnic minorities, average age = 41.6 [SD = 10.1]) a multisite behavioral intervention study for AUD in the United Kingdom. The Form-90 was used to collect alcohol use data, the Short Form Health Survey and Quality of Life measures were used to assess pain, and negative affect was assessed using the Brief Symptom Inventory (COMBINE) and the General Health Questionnaire (UKATT). RESULTS: Pain scores were significantly associated with drinking outcomes in both datasets. Greater pain scores were associated with greater negative affect and increases in pain were associated with increases in negative affect. Negative affect significantly mediated the association between pain and drinking outcomes and this effect was moderated by social behavior network therapy (SBNT) in the UKATT study, with SBNT attenuating the association between pain and drinking.

Significance: This paper provides a perspective on how translational research on stress-related mental disorders is being powered by an ever-developing appreciation of the shared neural circuits and genetic architecture that moderate the response to stress across species. It also addresses research approaches that have the potential to deliver a new generation of risk biomarkers and therapeutic strategies for stress-related disorders.
In our ongoing efforts to advance understanding of human diseases, translational research across rodents and humans on stress-related mental disorders stands out as a field that is producing discoveries that illuminate mechanisms of risk and pathophysiology at a brisk rate. Here we offer a Perspective on how a productive translational research dialog between preclinical models and clinical studies of these disorders is being powered by an ever-developing appreciation of the shared neural circuits and genetic architecture that moderate the response to stress across species. Working from these deep foundations, we discuss the approaches, both traditional and innovative, that have the potential to deliver a new generation of risk biomarkers and therapeutic strategies for stress-related disorders.

Significance: Alcohol is a leading cause of liver failure worldwide. However, treatments for alcoholic liver disease are limited, and the management of patients with AUD who require liver transplant may be challenging. This paper critically reviews and discusses the clinical, public health, and bioethical issues related to the treatment of AUD in patients before and after liver transplant. The review also highlights the critical need to address smoking in this population. (Lee MR, Leggio L. American Journal of Psychiatry 2015 Dec 1;172(12):1182-9) [no abstract]
Can a criminal justice alcohol abstention programme with swift, certain, and moderate sanctions (24/7 Sobriety) reduce population mortality? A retrospective observational study
Significance: A rigorous evaluation of the 24/7 sobriety program for alcohol-involved offenders in South Dakota found the program was linked to a surprisingly large (4.2%) reduction in all-cause mortality. These findings, drawn from a strong statistical design, suggest but do not show that the program has spillover effects on members of the population who are not enrolled in the program.
Background: In the UK and USA, various jurisdictions have launched new approaches for managing alcohol-involved offenders that might have public health implications. These programmes require participants to abstain from alcohol and submit to frequent alcohol testing with swift, certain, and modest sanctions for violations, with the aim to reduce crime and keep alcohol-involved offenders in the community. In this study we examine whether the 24/7 Sobriety programme in South Dakota, USA—the largest such programme to date—is associated with reductions in mortality. Methods: With a differences-in-differences design, we used variation in the timing of 24/7 Sobriety implementation across South Dakota counties between 2005 and 2011 to estimate the association between programme introduction and county-level mortality. We used monthly, county-level, aggregate counts for mortality from January, 2000, to June, 2011. We assessed total deaths, and deaths due to external injuries, circulatory disorders, digestive disorders, and cancer (as a potential placebo). Findings: Between January, 2005, and June, 2011, 16 932 people (about 3% of the adult population) participated in the 24/7 Sobriety programme. The analysis was based on a sample size of 9 108 county-month observations (ie, 66 counties × 12 months × 11·5 years). Implementation of 24/7 Sobriety was associated with a 4·2% (95% CI 1·5–6·9) reduction in all-cause adult mortality, with the largest associations among women (8·0%, 95% CI 3·9–11·8) and individuals older than 40 years (4·3%, 95% CI 1·4–7·0). Associations were most evident among circulatory disorders. Interpretation: 24/7 Sobriety might have public health benefits, which could extend beyond individuals directly enrolled in the programme. However, further research, including randomised controlled trials and analyses of individual-level data, is needed to corroborate the finding, reassess the size of these associations, and gain insight into causal mechanisms. Should a negative association be replicated, it might represent a substantial advance in our understanding of how criminal justice interventions could help shape public health.

Significance: This review addressed sex differences in preclinical animal models of addiction. Female rats, in general, acquire the self-administration of drugs and alcohol more rapidly, escalate their drug-taking with extended access more rapidly, and show more motivational withdrawal, and greater reinstatement (when tested in animal models of craving). The one exception is that female rats show less motivational withdrawal to alcohol. These sex differences appear to be both organizational (i.e., estradiol-treated neonatal animals show the male phenotype), and activational (i.e., female phenotype depends on the effects of gonadal hormones.) Differences within the estrous cycle are relatively minor and most prevalent during the acquisition of drug taking and less influential once compulsive drug taking is established. A better understanding of how males and females differ will help scientists design experiments to characterize better the presence or absence of sex differences in new phenomena that they are investigating.
The purpose of this review is to discuss ways to think about and study sex differences in preclinical animal models. We use the framework of addiction, in which animal models have excellent face and construct validity, to illustrate the importance of considering sex differences. There are four types of sex differences: qualitative, quantitative, population, and mechanistic. A better understanding of the ways males and females can differ will help scientists design experiments to characterize better the presence or absence of sex differences in new phenomena that they are investigating. We have outlined major quantitative, population, and mechanistic sex differences in the addiction domain using a heuristic framework of the three established stages of the addiction cycle: binge/intoxication, withdrawal/negative affect, and preoccupation/anticipation. Female rats, in general, acquire the self-administration of drugs and alcohol more rapidly, escalate their drug taking with extended access more rapidly, show more motivational withdrawal, and (where tested in animal models of "craving") show greater reinstatement. The one exception is that female rats show less motivational withdrawal to alcohol. The bases for these quantitative sex differences appear to be both organizational, in that estradiol-treated neonatal animals show the male phenotype, and activational, in that the female phenotype depends on the effects of gonadal hormones. In animals, differences within the estrous cycle can be observed but are relatively minor. Such hormonal effects seem to be most prevalent during the acquisition of drug taking and less influential once compulsive drug taking is established and are linked largely to progesterone and estradiol. This review emphasizes not only significant differences in the phenotypes of females and males in the domain of addiction but emphasizes the paucity of data to date in our understanding of those differences.

Significance: This study used National Survey on Drug Use and Health (NSDUH) data to explore changes in alcohol use and associated outcomes among females and males aged 12 and up between 2002 and 2012. Although men still drink more than women, differences in the drinking patterns have narrowed for current drinking, number of drinking days per month, past year Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) alcohol abuse, and past-year driving under the influence of alcohol. Notably, the average number of drinking days and the percentage of people who drank in the previous 30 days increased for females and decreased for males. Among 18–25 year olds not in college, binge drinking increased among women, but decreased among men. The evidence of increasing alcohol use by females is particularly concerning given that women are at greater risk of a variety of alcohol-related health effects, including liver inflammation, cardiovascular disease, neurotoxicity and cancer.
Background: This study confirms other recent reports about changing patterns of alcohol use by men and women in the United States. The evidence of increasing alcohol use by females is particularly concerning given that women are at greater risk of a variety of alcohol-related health effects, including liver inflammation, cardiovascular disease, neurotoxicity and cancer. Females in the United States consume less alcohol and cause and experience fewer alcohol-related harms than males. However, recent research suggests such gaps might be narrowing. The purpose of this study was to explore changes in alcohol use and associated outcomes among females and males in the United States between 2002 and 2012. METHODS: Data from the National Survey on Drug Use and Health were used to assess the prevalence and trends for females and males aged 12+ in lifetime abstinence, age of onset, current drinking, binge drinking, drinking and driving, reaching DSM-IV criteria for an alcohol use disorder, combining alcohol with other drugs such as marijuana, and other variables. Of particular interest was whether differences between females and males narrowed during the decade under study. RESULTS: Differences in the drinking patterns of females and males aged 12+ narrowed between 2002 and 2012 for current drinking, number of drinking
days per month, past year DSM-IV alcohol abuse, and past-year driving under the influence of alcohol. In addition, convergence was noted in 1 or more age subgroups for the prevalence of binge drinking and DSM-IV alcohol dependence and mean age at drinking onset. Divergence in drinking habits did not occur for any measure in any age subgroups with the exception of a greater increase in the prevalence of combining alcohol with marijuana among young adult male drinkers than female drinkers aged 18 to 25. CONCLUSIONS: Between 2002 and 2012, differences in alcohol consumption and related outcomes narrowed for females and males. Reasons for converging patterns of alcohol use are unclear and do not appear to be easily explainable by recent trends in employment status, pregnancy status, or marital status. More research is needed to identify the psychosocial and environmental contributors to these changes and to assess implications for prevention and treatment efforts.

Significance: This study assessed the effectiveness of a web-based, combined sexual assault risk and alcohol use reduction program for college women using a randomized controlled trial. For women with a history of sexual assault, participating in the combined web-based intervention (compared to participating in face-to-face risk reduction programs) reduced sexual assault risk and heavy episodic drinking. Notably, the combined intervention was only effective in reducing sexual re-assault rates and not first sexual assault experiences. These data suggest that web-based personalized feedback programs targeting sexual assault may be a cost-effective option for reducing sexual assault and heavy episodic drinking on college campuses.
Sexual assault risk reduction programs do not target alcohol use despite the widespread knowledge that alcohol use is a risk factor for being victimized. The current study assessed the effectiveness of a web-based combined sexual assault risk and alcohol use reduction program using a randomized control trial. A total of 207 college women between the ages of 18 and 20 who engaged in heavy episodic drinking were randomized to one of five conditions: full assessment only control condition, sexual assault risk reduction condition, alcohol use reduction condition, combined sexual assault risk and alcohol use reduction condition, and a minimal assessment only condition. Participants completed a 3-month follow-up survey on alcohol-related sexual assault outcomes, sexual assault outcomes, and alcohol use outcomes. Significant interactions revealed that women with higher severity of sexual assault at baseline experienced less incapacitated attempted or completed rapes, less severity of sexual assaults, and engaged in less heavy episodic drinking compared to the control condition at the 3-month follow-up. Web-based risk reduction programs targeting both sexual assault and alcohol use may be the most effective way to target the highest risk sample of college students for sexual assault: those with a sexual assault history and those who engage in heavy episodic drinking.

New NIAAA Video Page
In December 2015, NIAAA launched a new landing page to host select videos. Current clips include interviews and presentations by Drs. George F. Koob and Vivian Faden, as well as other NIAAA researchers. The videos on the site will spotlight topics such as underage drinking, FASD, treatment options, alcohol biosensors, and college drinking, as well as include LabTV videos and public service announcements. The new video page can be found at: http://www.niaaa.nih.gov/publications/video-bank.
Digitizing the NIAAA Library
The NIAAA library includes physical copies of books, journals, government documents, legislation, as well as individual articles and book chapters. Until recently, this collection was entirely stored at an NIAAA contractor's warehouse. To make the library's resources more accessible, NIAAA has been working with the Substance Abuse Librarians and Information Specialists (SALIS) organization to digitize and upload selected items to the SALIS Collection of the Internet Archives. More than 500 items, including the NIAAA monographs, are now available at: http://www.archive.org/details/salis?and=NIAAA.
