Screening, Evaluation and Assessment (SEA) Protocol at the NIDA IRP

Background: People who will participate in research studies need to undergo proper screening, evaluation, and assessment (SEA). SEA helps keep those who participate in studies safe. It also helps ensure accurate study results. The National Institute on Drug Abuse (NIDA) Intramural Research Program (IRP) wants to screen people with alcohol and/or substance use disorders (ASUD) as well as people without ASUD for ongoing studies at NIDA in Baltimore, MD Objective: To screen people with or without ASUD for ongoing studies at NIDA. The ultimate goals are to learn why some people (1) use drugs; (2) stop using drugs; (3) use drugs but do not get addicted; and (4) never use drugs snd to develop ASUD treatments. Eligibility: People aged 18 years and older. They may (1) currently use nicotine, alcohol, opioids, cocaine, or other drugs; (2) no longer use them; or (3) have never used them. Design: Participants will have 1 screening visit that could last up to 8 hours. The visit may be split over more than 1 day. The duration of the screening may vary for each individual based on which studies they are interested in and screened for. The tests they undergo may vary and may include the following: * Physical exam. * Blood, saliva, and urine tests. * Breath samples that test for alcohol and carbon monoxide. * Test of heart function. * Smell test that measures sense of smell. * Tests of memory, attention, and thinking. * Mental health evaluation. * Mock magnetic resonance imaging (MRI) scan. * Questionnaires about alcohol and other drug use, mental health, medical history, and life in general.

Environment and Alcohol: A Pilot Study

Background: Alcohol use disorder (AUD) is a chronic disease that causes more than 140,000 US deaths each year. AUD treatment often includes therapy and medication. Some people with AUD may also benefit from behavioral and lifestyle changes. Objective: To evaluate the effects of different activities and environments on drinking behaviors and mental health in people with AUD. Eligibility: People aged 21 years and older with AUD. Design: Participants will have up to 10 study visits in Baltimore. Participants will have a baseline visit. They will have a physical exam with blood and urine tests. They will have a breath test for alcohol and a test that measures body composition. They will answer questions about their alcohol and substance use; mental and physical health; mood and anxiety; and sleep quality. Participants will download an app called MetricWire. The app will send 3 sets of questions to be answered at different times throughout the day. The study visits will include 2 stages: 1. Active stage. On these visits, participants will use a virtual reality system called the Meta Quest Pro (MQP) as they choose. Then they may choose among video games, puzzles, books, crafts, and other activities.. These sessions will last for 3 hours. 2. Passive stage. On these visits, participants will watch videos selected by the research team. These sessions will last for 3 hours. On the last visit of each stage, participants will sit in a room that looks like a bar. They will answer questions about their cravings, their urge to drink, and how many drinks they would buy. Participants will be served 1 drink containing alcohol. They will be asked about their cravings and subjective effects of alcohol after drinking it.

Addictions Neuroclinical Assessment (ANA)

Background: Alcohol use disorder (AUD) is a major public health problem. In the U.S., 16 to 18 million adults have an AUD. Researchers want to test an assessment tool called the ANA. It uses self-report and behavioral measures to assess 3 neuroscience domains of addiction. They hope to better understand, manage, prevent, and treat AUD. Objective: To learn how people s brains function related to their drinking. Eligibility: People ages 18 years and older who have enrolled in NIAAA natural history study 14-AA-0181. Design: Participants will complete surveys and tasks on a computer. The surveys and tasks assess a range of aspects of thinking and making decisions. The surveys and tasks also assess behaviors and feelings about alcohol and other rewards, and negative emotions. Participants will spend 90 minutes on the computer. Then they will take a break. In total, they will spend 4 blocks of time on the computer. Each block will last 90 minutes. They will take a break in between each block of time. They can take more breaks if needed. Outpatient participants and healthy volunteers will complete this study in 1 visit. It will last about 6 hours. A second visit may be scheduled if needed. Outpatient participants will take a breath alcohol test. If their test is positive, their visit may be rescheduled or they may be withdrawn from the study. Inpatient participants will complete this study over several days. Data collected from participants in this study may be combined and analyzed with their data from NIAAA study 14-AA-0181 and/or NIAAA imaging study 14-AA-0080.

Impact of Federal and State Medications for Opioid Use Disorder (MOUD) Policy Changes During the Pandemic

"Gold-standard" medications for opioid use disorder (MOUD) treatment combines FDA-approved medications, primarily methadone and buprenorphine, with behavioral therapies to provide "whole-patient" treatment. Prior to the pandemic, methadone and buprenorphine were subject to greater federal regulations than medications for other substance use disorders, including medication for alcohol use disorder (MAUD), which created barriers to MOUD initiation and retention. These barriers were exacerbated by physical distancing and diminished clinic capacities during the COVID-19 pandemic. To prevent healthcare disruption and expand access to MOUD treatment during the public health emergency, federal and state authorities implemented several MOUD policy changes during the pandemic to reduce barriers to MOUD initiation and retention, which subsequently became permanent. This study is an evaluation of the impacts of these policies on treatment use, retention, and patient outcomes pre- and post-MOUD policy implementation.

Spironolactone in Alcohol Use Disorder (SAUD)

Background: Alcohol use disorder (AUD) affects about 29.5 million people in the United States. Only 3 medicines have been approved by Food and Drug Administration to treat AUD. Researchers want to find better treatments for AUD. Animal studies found that a medicine called spironolactone, may decrease the amount of alcohol the animals drank. Spironolactone is approved to treat high blood pressure, or heart failure in people. It is not approved to treat AUD. Objective: To test a medicine (spironolactone) in people who sometimes drink excessive alcohol in order to understand how the body breaks down spironolactone and if there are any side effects in people who drink alcohol while taking this medicine. Eligibility: People aged 21 and older with AUD. Design: Participants will have 4 separate 7-day stays at a clinic in Baltimore over 2 months. Spironolactone is a capsule you swallow. Participants will take a capsule twice a day for 5 days during each clinic stay. During 1 of their 4 stays, they will take a placebo instead of the medicine. The placebo capsule looks just like the spironolactone capsule but contains no medicine. Participants will not know when they are taking the medicine or the placebo. Participants will not drink alcohol until day 6 of each clinic stay. Then they will be asked to drink alcohol in a bar-like area in the clinic. Their breath and blood alcohol levels and their well-being will be measured. Participants will undergo other tests in the clinic: A DEXA (dual energy X-ray absorptiometry) scan uses X-rays to measure bone density and muscle mass. Participants will lie on an open-top, padded table, then a small arm will scan the full length of their body. The radiation participants will get in this study is about the same as from one regular x-ray. Blood tests. Participants may feel some discomfort at the site of needle entry. Electrocardiogram. This test records the heart activity. Sensors are attached to the skin with stickers and removed after a few minutes. Urine tests. All urine will be collected over a 3-day period during each stay. We will measure the amount of urine, and different hormones and salts in the urine. Questionnaires and tasks. Participants will answer questions about their alcohol use. They will perform tasks to test mood, craving, mental and physical coordination, and how much they feel an effect from alcohol after drinking.

Semaglutide Therapy for Alcohol Reduction (STAR)

Background: Alcohol use disorder (AUD) is a problematic pattern of alcohol use accompanied by clinically significant medical consequences. Medications can help most people reduce their drinking, but the number is limited, and additional treatment options are needed. Objective: To test if a medication named Semaglutide may reduce alcohol drinking in people with AUD. Who can participate? All Adults aged 18 or older with AUD might be eligible to participate in the study. What will happen during the study? Participants will visit the National Institute on Drug Abuse (NIDA) in Baltimore once a week for about 20 weeks (5 months). Each visit will last between 2 and 6 hours depending on the tasks scheduled for that visit. Participants will be assigned by chance (like flipping a coin) to receive either Semaglutide or placebo. A placebo looks just like a real drug but contains no medicine. The study medication is given as a shot under the skin each week. Participants will undergo different tests throughout the study: They will give blood, urine, and saliva samples. They will engage in self-paced behavioral therapy on a computer. They will answer questions about their mood, diet, alcohol drinking and craving, tobacco use, etc. They will taste several sweet liquids and tell their preferences. They will sit in a bar-like room and be exposed to cues that might make them feel the urge to eat food or drink alcohol. They will wear a virtual reality headset that creates a cafeteria setting. They will walk the virtual cafeteria and choose food and drinks from a buffet. They will have a functional magnetic resonance imaging (fMRI) scan to take pictures of their brain. During the scans, participants will be shown pictures of alcohol-containing drinks, food, and other items.They will perform tasks on a computer screen. Participants will have a follow-up visit about 7 weeks after their last shot.

Social Cognition in Severe Alcohol Use Disorder

With 41,000 deaths per year, alcohol consumption is the second leading cause of preventable mortality in France. Nearly 3.4% of adults engage in excessive and chronic alcohol use, meeting criteria for Severe Alcohol Use Disorder (SAUD). SAUD is associated with cerebral and cognitive alterations, including deficits in social cognition. These deficits manifest as difficulties in perceiving and interpreting social cues during interactions and encompass, in particular, the recognition of emotional facial expressions and the accurate attribution of others' beliefs, emotions, and intentions (i.e., theory of mind). Such alterations contribute to interpersonal difficulties and psychological distress and are recognized as risk factors for the development and maintenance of SAUD. To date, social cognition has primarily been explored through behavioral tests, providing a description of deficits without examining their neuro-structural correlates. Moreover, no neuroscientific study has investigated the impact of sex and concomitant tobacco use on social cognition and associated brain structures in SAUD, although these factors are known to influence both social cognitive abilities and cerebral organization in this disorder. Finally, the everyday consequences of these alterations on social functioning and the trajectory of alcohol consumption remain poorly explored. In this context, the present project aims, first, to explore the neuro-structural correlates of social cognition deficits in SAUD using psychometric assessments (i.e., emotion recognition, theory of mind) combined with magnetic resonance imaging (MRI). The impact of sex and tobacco use will be accounted for by including these variables as covariates in statistical analyses. Second, the project seeks to assess the daily-life impact of social cognition deficits on the social functioning of individuals with SAUD (i.e., quantity and quality of social interactions) and on the evolution of alcohol use behaviors six months after hospitalization (i.e., risk of relapse). The study will include two participant groups: individuals with SAUD and age-, sex-, and education-matched control participants. The expected results will refine our understanding of social cognition alterations in SAUD, thereby contributing to the improvement of current neuroscientific models. These advances will pave the way for the identification of potential targets for prevention programs and therapeutic interventions.

Improving Alcohol Use Disorder Treatment for Gender Minority Populations

Gender minority (GM; transgender and gender non-conforming) individuals experience disproportionately high rates of hazardous drinking and alcohol use disorder (AUD) and are an NIH-designated disparity population (NOT-MD-19-001). Despite marked disparities and unique alcohol risk factors, there are no evidence-based alcohol interventions for this population. This study will conduct mixed-methods formative research with an established multi-site longitudinal GM cohort to develop and assess the feasibility of the first culturally-adapted psychosocial treatment intervention for GMs with AUD. The study will evaluate an adapted version of interpersonal psychotherapy (IPT), with adaptations intended to enhance the responsiveness of IPT to the unique life experiences of GM individuals that may influence alcohol consumption.

Acute Effects of Alcohol on PET Imaging of Phosphodiesterase-4B (PDE4B)

Background: Phosphodiesterase-4B (PDE4B) is a protein in the brain that may play a role in several mental health disorders. Researchers want to know if drinking alcohol increases the binding of a radioactive tracer to PDE4B in the brain because of increased activity and/or amount of the protein. This knowledge may help create new ways to treat people with alcohol use disorder (AUD). Objective: To learn if alcohol increases PDE4B activity in the brain. Eligibility: Healthy people aged 21 to 70 years who drink socially but do not have AUD. They must be enrolled in protocol 14-AA-0181"NIAAA Natural History Protocol". Design: Participants will have up to 4 clinic visits with up to 3 imaging scans of the brain; these will include 1 or 2 positron emission tomography (PET) scans and 1 magnetic resonance imaging (MRI) scan. The first PET scan will be a baseline. Participants will receive a radioactive tracer through a tube inserted into a vein. A second tube will be inserted so that blood can be drawn during the scan. Participants will lie on a bed that slides into a doughnut-shaped machine. This visit will take about 6 hours. For the next PET scan, participants will receive alcohol (ethanol) through a tube in a vein until they have a blood alcohol concentration that is equal to the legal driving limit. This is the same as 4 or 5 drinks for most people. After the scan, participants must remain at the clinic for a few hours until their blood alcohol drops. This visit will take 14 to 16 hours. The MRI scan of the brain will take up to 2 hours in a separate clinic visit.

Neural and Hormonal Influences on Sex Differences in Risk for AUD

The sex gap in alcohol consumption is closing rapidly, due to alarming increases among women. From 2002-2013, Alcohol Use Disorder (AUD) increased 84% for women, compared to 35% for men. As such, there is an urgent need to determine the factors underlying sex differences in risk for AUD. Current addiction models propose three domains that drive problematic alcohol use and serve as candidate sex-specific risk factors: executive function, negative emotionality, and incentive salience. Data suggest that poor inhibitory control, a key component of executive function, is a stronger risk factor for women than for men. Moreover, there is have preliminary evidence that female drinkers show less engagement of neural inhibitory circuitry, and that this sex difference is influenced by estradiol. However, the degree to which hormonally-moderated sex differences in executive function extend to the negative emotionality and incentive salience domains, and how these sex differences influence current and future drinking is unknown. The goal of this study is to identify the mechanisms underlying sex-specific risk for AUD, and ultimately to help develop sex-specific prevention and treatment efforts. The overall objective of this trial is to determine the neural and hormonal factors contributing to sex-specific risk for AUD in three addiction domains: inhibitory control (executive function), negative emotionality, and alcohol cue reactivity (incentive salience).

Sex Differences in the Response to Abstinence From Alcohol.

In laboratory animals, repeated cycles of abstinence from and return to alcohol drinking can lead to changes in alcohol intake. In a study of the effect of abstinence on drinking in humans, the investigators found evidence that abstinence affects drinking differently in women compared to men. In the present study, the investigators propose to study how men and women respond to abstinence, and whether this information can be used to improve intervention and prevention strategies.
