Filter by:This is an observational study to identify the prevalence of advanced liver fibrosis among patients with excessive alcohol intake using a non-invasive method (FibroScan®) and to characterize the main environmental, genetic and epigenetic factors that could influence the development of advanced fibrosis. The investigators will include patients 21 years of age or older with excessive alcohol intake, with abnormal AST, ALT, GGT and/or bilirubin, and without any evidence of decompensated liver disease (jaundice, ascites, encephalopathy). Liver fibrosis will be estimated by FibroScan®. A designed questionnaire for studying environmental and psychosocial factors will be filled by the included patients, and blood samples will be obtained to study genetic and epigenetic factors. The patients with advance fibrosis will be referred to the specialist for surveillance and treatment according to current clinical guidelines.
This study uses techniques from an area of research known as neuroeconomics, which integrates concepts and methods from psychology, neuroscience, and economics to better understand how people make decisions and how these decisions are supported by the brain. One neuroeconomic concept that is especially relevant in the area of addictions is substance demand, or how consumption of a commodity (e.g., alcohol, tobacco, or drugs) is influenced by price and other factors. Previous studies have shown that alcohol demand is related to severity of alcohol misuse, drinking quantity/frequency, and treatment outcomes. In addition, we know that alcohol demand can also fluctuate in response to environmental cues such as alcohol-related stimuli or external contingencies such as important responsibilities the following day. These increase and decreases in consumption and value are clinically significant because they help us understand how people with alcohol use disorders are able to successfully or unsuccessfully modulate their drinking behaviors. This study is examining how the brain responds in these situations and whether these responses differ as a function of severity of alcohol misuse. This study will use functional magnetic resonance imaging (fMRI) to understand brain activity patterns associated with changes in the value of alcohol in the presence of alcohol-related beverage cues relative to neutral-related beverage cue. Participants will be non-treatment-seeking adult heavy drinkers who are recruited from the community to participate in an fMRI scan. During the scan, participants will make decisions about how many alcohol beverages they would consume (hypothetically) at various prices while their brain activity during those decisions is measured. The first experimental manipulation involves an in-scanner alcohol cue exposure task in which the drinking decisions will be made after viewing high-quality images of alcoholic (beer/wine/liquor) beverages or neutral (water/juice/soft drinks) beverages.
The objective of this study is to make a suicide screening in the entire population of Milpa Alta (approximately 150,000 inhabitants), taking into account other outcomes such as depression, anxiety, alcohol and drugs. For this, an app for Smartphone (MeMind) or a web platform (www.MeMind.net) will be used in which the participants will take a self-administered questionnaire, composed of several psychometric instruments . It is expected that 70% of the population between 15 and 70 years old can do so directly with their own Smartphone, although web access posts will be enabled in educational and municipal units to avoid discrimination based on age or access to technology. Our main hypothesis argues that the early identification of people at risk in almost the entire community can be done with an App for Smartphone, serving to depict a map of mental health and related needs of the population, serving for the planning of healthcare services of the local environment, and ultimately for the best assistance of groups and individuals with greater needs through their identification and early reference to medical assistance.
Few medications are currently Food & Drug Administration (FDA)-approved for the treatment of Alcohol Use Disorder (AUD), and those that are have, on average, modest effects on drinking. "Precision medicine" research has explored whether patient-level variables, such as genetic variation, may identify subgroups of individuals with larger medication effects, but few findings have been replicated. A promising novel medication for AUD is brexpiprazole (BREX), a serotonin/dopamine activity modulator (SDAM). The investigators conducted a prior study in which the effects of another SDAM, aripiprazole, were influenced by genetic variation in the gene encoding the dopamine transporter (DAT1). This study will evaluate the effects of two doses of BREX, relative to placebo, among non-treatment-seeking individuals with AUD, and will test whether DAT1 genotype influences these effects. Primary outcomes are drinking under natural conditions and in a laboratory paradigm. Functional magnetic resonance imaging (fMRI) will be used to explore whether BREX effects on brain activation associated with cognitive control or elicited by alcohol cues accounts for its effects on drinking. The investigators hypothesize that BREX, relative to placebo, will reduce drinking under natural conditions and in the lab, and will do so to a greater extent among individuals who carry the DAT1 9-repeat allele, relative to those homozygous for the 10-repeat allele. If these hypotheses are supported, BREX may represent a novel pharmacogenetic treatment for AUD.
Phosphatidylethanol (PEth) is a direct biomarker of alcohol that can detect moderate to heavy drinking with high sensitivity and specificity over 3-week periods. Reinforcing negative PEth results alongside attendance may increase the proportion of participants who respond to CM during and post treatment. In the proposed study, the investigators will collect PEth samples every 3 weeks for 12 weeks in 150 participants initiating outpatient treatment for alcohol use disorders. Using a two-group randomized design, participants will be assigned to standard care with PEth monitoring alone or with CM for attending treatment and submitting PEth negative samples. Compared to standard care and monitoring, the investigators expect that the CM intervention will result in greater attendance, more PEth negative samples, and higher proportions of self-reported non-drinking days, along with lower proportions of heavy drinking days, over the short term and the long term, measured throughout a 12-month follow-up. The investigators anticipate that the reinforcement intervention may decrease other drug use and sexual risk behaviors that spread HIV, reduce psychiatric symptoms, and improve quality of life as well.
Alcohol use disorders (AUDs) affect up to 60% of individuals with bipolar disorder during their lifetime-a rate 3 to 5 times higher than what occurs in the general population. The mechanisms that contribute to elevated rates of comorbidity are not known. Early identification in individuals with bipolar disorder who are at risk for AUDs could inform novel intervention strategies and improve life-long outcomes. The primary objective of this protocol is to use alcohol administration procedures and functional MRI techniques to investigate subjective response to alcohol, compared to placebo, and relationship with functional responses of, and connectivity among, brain regions in ventral prefrontal emotional networks in young adults with bipolar disorder and healthy comparison young adults. Baseline clinical and structural MRI assessments will be completed in 30 bipolar and 30 healthy young adults (21-26 years of age, 50% women). Then, following standard beverage administration procedures, participants will complete within-person, counter-balanced, fMRI scans and complete measures of subjective response to alcohol while under the influence of alcohol or placebo. Specifically, individual differences in the experience of stimulating, sedative, and anxiolytic effects of alcohol (measured with self-report surveys) and individual differences in neural responses to alcohol within ventral prefrontal emotional networks will be investigated and differences in bipolar disorder compared to healthy participants assessed. Functional MRI scans during a continuous performance task with emotional and neutral distractors (CPT-END) and at rest will be collected while under the influence of alcohol and placebo and compared. Experience of stimulating, sedative, and anxiolytic effects of alcohol from self-report survey data and neural responses to emotional stimuli while under the influence of alcohol compared to placebo will be the primary data outcomes assessed. Additionally, associations between subjective and neural response to alcohol and drinking patterns will be explored (secondary outcomes). The primary endpoint of the study will be after completion of both alcohol and placebo beverage conditions.
This project will develop and pilot test a new smartphone-based system for AUD patients, their partners, and clinicians called PartnerCHESS. PartnerCHESS will integrate key features of ABCT and A-CHESS. PartnerCHESS will also include a Clinician Report to automatically alert clinicians of patients at risk of relapse and offer other information on how recovery is proceeding. The project has three specific aims: 1. Integrate A-CHESS with key features of ABCT to create PartnerCHESS to serve patients, partners, and clinicians. 2. Conduct a pilot test (a small randomized clinical trial) of PartnerCHESS to estimate effect size and refine the protocol, procedures, recruitment strategy, measurements, and operations for use in a large RCT. 3a. Decide whether to pursue an R01 application, and if so, 3b. plan for the R01.
The approach and avoidance task (AAT) has evolved as a promising treatment add-on in the realm of psychology. Certain psychiatric diseases, such as behavioural addictions, social anxiety disorder, and arachnophobia, are characterized by a dysfunctional tendency to either approach or avoid disease-specific objects. This tendency can be measured by means of the approach and avoidance task. In this so-called diagnostic AAT participants are instructed to react upon the format or the frame colour of a picture. For instance, pictures have to be pushed away if they are presented in landscape format and pulled towards oneself if they are presented in portrait format (or vice versa). Hence, the format (or the frame colour) becomes the task-relevant dimension, whereas the content of the picture becomes the task-irrelevant dimension. However, what generally becomes obvious in the psychiatric diseases mentioned above is that the task-irrelevant dimension (picture content) exerts an influence on reaction times. For instance, alcoholic patients are generally faster to respond if alcoholic pictures are presented in a format requiring them to pull towards themselves and slower to respond if alcoholic pictures are shown in the format requiring them to push away a joystick. This behavioural tendency has been termed an approach bias for alcohol. In order to counteract these dysfunctional approach or avoidance tendencies, an AAT-training has been developed. In this training participants/patients learn to either avoid or approach disease-specific objects. Alcohol-dependent patients, for instance, learn to avoid alcohol-related pictures by pushing or swiping the image away. It has been shown that these trainings can enhance treatment outcome (e.g. lower relapse rates) among alcohol-addicted patients (Wiers, Eberl, Rinck, Becker, & Lindenmeyer, 2011). The aim of the current study is to test whether the avoidance gesture is as important as suggested by the AAT's name or whether inhibiting the urge to approach alcoholic content might be enough to bring about the effect.
The present study focuses on examining the feasibility, acceptability, and preliminary effects of an adapted alcohol intervention for high-risk college students attending community colleges. Investigators adapted BASICS (an efficacious in-person intervention developed for high-risk drinkers attending 4-year colleges and universities) to a web-conferencing format that allows the facilitator and participant to see and discuss live web-based personalized feedback. SMS text messages with protective behavioral strategies were also provided. The objective of the R34 was to establish feasibility and acceptability as well as to determine preliminary or likely effect sizes.
The objectives of this VA Merit application are to identify a neural target unique to Veterans with co-occurring alcohol use disorder and mild traumatic brain injury (AUD+mTBI) and to test the efficacy of this target as a stimulation site for repetitive transcranial magnetic stimulation (rTMS) treatment to maximize functional recovery. rTMS will soon be a treatment option at 30 VAs nationwide and preliminary studies show promise for AUD and mTBI treatment. A better understanding of how AUD+mTBI impacts the brain needs to occur in order to advance rTMS to optimize function. This research is aligned with the VA RR&D's mission to generate knowledge and innovations to advance the rehabilitative health and care of Veterans, to effectively integrate clinical and applied rehabilitation research, and translate research results into practice. This research is also aligned with the goal of the Psychological Health & Social Reintegration portfolio to develop interventions improving psychological health status of Veterans enabling them to function more fully in society.
