Effect of Acute Alcohol Intoxication on Neural Processes During Decisions to Engage in HIV Risk Behaviors

Background: People who binge drink are more likely to have risky sexual encounters, and alcohol changes brain activity associated with reward decisions related to those behaviors. Researchers want to better understand how alcohol s effects on risky sexual behavior that might lead people to contract sexually transmitted diseases (STDs) like HIV, the virus that causes AIDS. Objective: To study how alcohol impacts decisions about engaging in risky sex. Eligibility: Healthy adults ages 21-65 without alcohol use disorder Design: Participants will have 2 study visits, 1 month apart. They will arrive and depart via taxi. They will consume alcohol at 1 visit, chosen at random. At visit 1, participants will answer questions about HIV knowledge, HIV risk behaviors, and sexual interests. They will view pictures of clothed people and pick those they might have sex with. They will think about the person s risk of having an STD and whether they would use a condom during sex. At both visits, participants will sit in a bar-like room and have 2 drinks that may contain alcohol. Then they will have magnetic resonance imaging (MRI) brain scans. For this, they will lie on a table that slides in and out of a metal tube. The scanner makes loud noises; they will get earplugs. They will complete tasks that include looking at pictures and making choices about money. At the beginning of both visits the participants will be screened with urine drug test and pregnancy test. Duiring each visit the participants breath alcohol will be measured, and they will discuss whether they feel intoxicated. Participants will get snacks and stay at the clinic for up to 6 hours after the MRIs. ...

Effectiveness of an Intervention in Patients With Excessive Alcohol Consumption

Main objective: to verify the effectiveness of a brief intervention, based on the motivational interview (MI), in patients with excessive alcohol consumption assisted in Primary Care (PC). Design: a multicenter, randomized, cluster-controlled clinical trial with two parallel arms. PC professionals will be randomized to one of the two study groups: 1) Experimental Group (EG): MI-based approach; 2) Control group (CG): usual care. At least 50 family doctors, residents and nurses will participate, recruiting PC patients (n = 394). GE intervention: Training program to acquire specific skills on approaching risky alcohol consumption. It will consist of a workshop, with two video recordings of consultations with simulated standardized patients, before and after it, with each participant receiving formative feedback at the end. -Intervention GC: medical advice that is usually performed in these patients. To measure the knowledge and attitude of professionals in dealing with patients with alcohol consumption, they will fill out a validated questionnaire. In addition, expert evaluators, after viewing the video recordings, will fill out a check-list to check the attitude of each professional, using the EVEM Scale. -Study population: patients ?14 years of age with risky consumption, detected by the professional in health centers in the province of Córdoba (Spain). Sample size: Assuming a loss rate of 5%, and the "cluster design effect", the number of subjects to be recruited is estimated at 394 (197 / group). Intervention control mechanism: each participant will be audio-recorded with a real patient in a randomly chosen visit, evaluating her skills with the EVEM scale. The follow-up period for each patient will be 12 months, with 5 visits (initial, per month, 3 months, 6 months and 12 months) and 4 interleaved telephone contacts. The main outcome variable will be the level of self-reported alcohol consumption and the AUDIT questionnaire score. -Statistical analysis by intention to treat. Descriptive analysis and initial comparability of the groups will be carried out, and the effect of the intervention (dependent variable: abstinence or consumption reduction and AUDIT score) will be evaluated through bivariate and multivariate analysis.

A Hybrid Effectiveness Implementation Study of Latino/a Alcohol and Drug Users

Alcohol use is a significant problem among Latinxs and immigration-related stress increases risk for substance use. A theoretically-based cultural adaptation of motivational interviewing (CAMI) that specifically integrated discussion of immigration-related stressors (e.g., stigma, social isolation) resulted in significant reductions in alcohol-related harms for those Latinx heavy drinkers with high discrimination compared to standard MI, and reduced anxiety and depressive symptoms one year later compared to MI. Rigorous tests that examine theoretically-informed adaptation of efficacious addiction interventions are not common, yet are needed to advance implementation science. This Hybrid Type 1 Effectiveness-Implementation study will investigate the feasibility of implementing CAMI in a real-world clinical setting. The key questions are: Would CAMI have positive effects among individuals who use both drugs and alcohol? How do providers view this intervention? The investigators will collaborate with a primary care center that serves a mainly Latinx client population to train their Community Wellness Advocates (CWAs) to deliver CAMI to patients who are heavy drinkers. The investigators will conduct a concurrent investigation on the process of implementing CAMI in primary care - a two-arm randomized clinical effectiveness trial will enroll Latinx heavy drinkers (18 years or older) in primary care who use alcohol (and may use other drugs) - and follow them for 12 months after the intervention. Specific Aims are: (1) To examine the impact of CAMI plus a booster session (vs. assessment only) on outcomes: % heavy drinking days, frequency of alcohol-related consequences, depressive/anxiety symptoms, and number of illicit drug use days, using a Hybrid Type 1 Effectiveness-Implementation design and (2) To gather indicators of implementation outcome from multiple stakeholders using a mixed-methods approach. The investigators will follow Curran's framework to evaluate the process of implementation and Proctor's framework to measure implementation outcomes. This study, a first to examine the acceptability of culturally-adapted addiction treatments in primary care settings, will answer essential questions on implementing evidence-based care for Latinxs that can improve health disparities related to substance use. Long term goals are to translate the lessons from this Hybrid study to the broader community to focus on population health for all primary care patients.
