The Influence of Water and Salt Intake on Copeptin Levels During Moderate Alcohol Consumption
Alcohol DrinkingThe main interest of this study is to investigate the influence of moderate alcohol consumption (beer) on salt-water homeostasis. Therefore, 10 healthy volunteers will participate in 4 Intervention: Beer alone Beer and water Beer and salt (stock/bouillon) Water alone During the study day, copeptin, sodium, osmolality and urinary sodium/osmolality will be measured at 6 timepoints.

Alcohol Screening and Pre-Operative Intervention Research Study
Alcohol DrinkingThis study aims to learn more about how to improve patients' health before and after a scheduled surgery by examining acceptability and initial efficacy of pre-operative alcohol use reduction interventions.

Virtual Reality- Working Memory Retraining
Alcohol Use DisorderMild Traumatic Brain InjuryThis study will establish the acceptability and feasibility of enrolling and retaining heavy drinking Veterans with mild traumatic brain injury (mTBI) in an 8-week, randomized cross-over design trial of active VR working memory retraining (WMR). This study will also seek to establish the efficacy of active VR-WMR to increase performance in executive function.

Probiotics, Immune Function, and the Brain in Alcohol Consumers
Alcohol; UseProblemThis pilot project is a brief, open-label clinical trial of probiotics as an intervention in heavy drinkers. Heavy drinkers who do not yet show significant signs of liver disease may stand to benefit from probiotics, but no clinical trials to date have addressed this population. This study will recruit heavy drinkers to complete an open-label within-subjects trial. The study will investigate effects of probiotics on specific biomarkers in healthy heavy drinkers who currently are not seeking to change their alcohol use (i.e., are non-treatment-seeking).

Smartphone Technology: Young Adult Drinking
Alcohol UseAlcohol Drinking1 moreExploring technology based tools to reduce drinking is important. The purpose of this research study is to compare different BAC monitoring apps for their effects on alcohol drinking and ratings of usability among young adults.This study will be conducted in six phases: a web-based and in-person screening assessment; brief counseling session on the day before the alcohol drinking session; brief appointment on the day of the alcohol drinking session; alcohol drinking session; two-week field period; and a follow-up appointment. Participation in this study will last approximately two months.

Web-Based Training for EAP Alcohol Screening, Brief Intervention, and Refer
Alcohol ConsumptionAlcohol AbuseThe goal of the proposed research is to complete the development of a web-based program to train Employee Assistance Program (EAP) and EAP-affiliated managed behavioral health organization (MBHO) practitioners to conduct screening, brief intervention, and referral to treatment (SBIRT) for problem alcohol use among working adults.

ARCH II Study (Alcohol Research Center on HIV Study II)
Alcohol ConsumptionHIV1 moreThis study is being done to learn about the interaction of alcohol consumption and HIV on brain function. The proposed study will have two broad objectives. The first is to incorporate functional neuroimaging (FMRI) approaches, along with additional Magnetic Resonance Spectroscopy (MRS) methods that will enable a delineation in both functional and cerebral metabolic disturbances affecting specific functional brain systems that are associated with the interaction of ethanol (ETOH) consumption on Human Immunodeficiency Virus (HIV)-associated brain dysfunction. Recent data indicate that HIV infected patients with heavy ETOH consumption have FMRI abnormalities and exhibit alterations on other neuroimaging measures compared to moderate drinkers and people who do not drink at all. The second objective is to examine the extent to which reductions in ETOH consumption among heavy drinkers with HIV infection result from a motivational intervention. The findings from this study will provide important information on how heavy ETOH and HIV interact to affect the brain functional responsiveness, and the extent of improvement that might be gained by reducing heavy ETOH use.

Effect of Heavy Alcohol Consumption on Farnesoid X Receptor (FXR) Signaling
Alcohol ConsumptionThe main purpose of this study is to see whether heavy drinking will interfere with a specific pathway, called FXR signaling in the liver. The abnormality of this pathway may lead to liver injury in some patients who drink heavily.

Influence of n-Acetylcysteine Maintenance on Alcohol Effects
Alcohol Use DisorderThis study will evaluate the behavioral effects of alcohol during placebo and n-acetylcysteine maintenance using sophisticated human laboratory methods.

The Impact of Alcohol Consumption on Tuberculosis Treatment Outcomes
TuberculosisAlcohol Consumption1 moreAfter HIV/AIDS, tuberculosis (TB) remains the second leading cause of death due to an infectious disease globally. Retrospective studies from many countries, including the United States and South Africa, have consistently reported that in addition to having a higher burden of TB disease, patients with problem alcohol use have worse TB treatment outcomes. This prospective study will attempt to clarify both behavioral and biologic causal mechanisms underlying the deleterious effects of problem alcohol use on TB treatment response.
