Filter by:Background: Significant sex differences exist in regard to alcohol use disorder (AUD) and alcoholic liver disease (ALD). To date, no studies have examined the brain-gut-microbiome (BGM) axis (which is the relationship between the gut, brain, and the bacteria within the gut) and sex-differences in AUD and ALD. Aims: 1) Demonstrate baseline sex differences in the microbiome and metatranscriptome of AUD and ALD and correlate those differences to severity, 2) determine if these baseline sex differences predicts abstinence or ALD related outcomes, and 3) show how altering the microbiome can decrease the severity of AUD and ALD in a sexdependent manner. Hypothesis: Our project is aimed to explore the hypothesis that sex-related differences of the BGM axis in AUD and ALD explains the variation in patient severity and outcome by sex, and that alterations of the BGM axis can decrease the severity of AUD and ALD in a sex-dependent manner. Methods: A pilot randomized placebo (VSL#3 vs placebo) control trial will be performed in patients with AUD and ALD for 6 months. Questionnaire data, clinical labs, serum, and feces for shotgun metagenomics will be collected at baseline, 3-months, and 6-months. Anticipated Results: Patients with severe AUD/ALD will have more microbes and microbial genes associated with inflammation. These differences will predict outcomes at 6-months and that changes of this baseline microbiome with VSL#3 will lead to more positive outcomes than placebo, with men having greater benefit from VSL#3 than women. Implications and Future Studies: The discovery of the mechanisms underlying sex-related differences in AUD/ALD is needed for the development of personalized recommendations for prevention and treatment in men and women
The purpose of this study is to develop transcranial magnetic stimulation (TMS), specifically TMS at a frequency known as theta burst stimulation (TBS), to see how it affects the brain and changes the brain's response to alcohol-related pictures. TMS and TBS are stimulation techniques that use magnetic pulses to temporarily excite specific brain areas in awake people (without the need for surgery, anesthetic, or other invasive procedures). TBS, which is a form of TMS, will be applied over the medial prefrontal cortex, (MPFC), which has been shown to be involved with drinking patterns and alcohol consumption. This study will test whether TBS can be used as an alternative tool to reduce the desire to use alcohol and reducing the brain's response to alcohol-related pictures.
The hyper- or hypo-attribution of risks is deeply related to the core pathological mechanisms of mental disorders and at the same time engaging in risky behaviors influences their course and outcomes. The investigators study risk perception, risk behaviors and underlying brain mechanisms in a longitudinal design in three groups of psychiatric patients who participate in a psychological intervention that is aimed to reduce risk behavior and increase risk perception. Patients with schizophrenia (SZ), alcohol use disorder (AUD) and both disorders (SZ + AUD) are recruited during psychiatric in-patient treatment and participate in a combined face-to-face and mobile intervention that starts before release and ends four weeks after discharge. The standardized 4-session face-to-face group intervention that is based on motivational interviewing (Miller & Rollnick, 2013) and relapse prevention (Marlatt & Donovan, 2005) and addresses the reduction of disorder-specific risk behaviors, i.e. alcohol use for AUD and SZ+AUD and medication non-adherence for SZ. After discharge, a 4-week ecological momentary intervention (EMI) supports participants to maintain abstinence from risk behaviors and to strengthen coping in high-risk situations relying on mental contrasting and implementation intentions (Oettingen & Gollwitzer, 2011). Participants will be assessed in fMRI and behavioral measurements and by self-report pre and post interventional phase, furthermore they participate in an ecological momentary assessment during the post-discharge phase which assesses risk behaviors, high-risk situations and risk perception in real life contexts.
Alcohol use disorder (AUD) is a multifaceted, chronic relapsing disorder suffered by millions of men and women in the United States. AUD is associated with disrupted sleep continuity and architecture, which impact health-related quality of life, and contribute to relapse. However, many alcohol-sleep interactions and their underlying mechanisms remain unclear, especially those involving AUD and chronic sleep problems. Rapid eye movement (REM) sleep is altered long into abstinence, with excess duration and intensity of REM sleep, which is a predictor of relapse. Emotion deficits, including affective flattening and mesocorticolimbic hypo-responsiveness to emotional stimuli, are also consistent findings in AUD and predictors of relapse. Here, our investigators bring these two components together, building on an emerging literature showing that REM sleep is important for neural emotion regulation, calibrating emotions to promote next-day adaptive emotional functioning. Our investigators propose that the REM sleep-emotion pathway is dysfunctional in AUD, contributing to the deficits in emotion regulation in AUD shown by us and others, which could then lead to increased craving and relapse. Our investigators study male and female AUD patients compared to age- and gender-matched healthy controls, using 2 within-subject sleep conditions: uninterrupted sleep; selective REM sleep reduction, followed by functional neuroimaging with emotion reactivity and regulation tasks the following morning. Our investigators aim to determine specific effects of experimental REM sleep reduction on next-day neural emotional reactivity in AUD compared to healthy controls and compared to a night of uninterrupted sleep
The Trial Assessing Light-Intensity Exercise on the Health of Older Breast Cancer Survivors pilot randomized controlled trial aims to evaluate the efficacy of a home-based, light-intensity physical activity intervention among 56 obese, older adult breast cancer survivors, in comparison to a usual care control condition.
This study aims to investigate the implementation and real-world effects of an intervention for harmful use of alcohol and psychoactive medicinal drugs among hospital inpatients. Due to the negative impact of alcohol consumption on health outcomes, a call for action has been made by the Norwegian Ministry of Health, with focus on screening patients for alcohol consumption and evidence-based tailored interventions for those with medium or high consumption. In addition, non-prescribed use of psychoactive medicinal drugs, or concomitant use with alcohol, can also have negative health effects, therefore improved monitoring of the use of these are warranted. Interventions will be introduced as routine procedures at Norwegian hospitals in the upcoming year, and 2500 patients receiving acute medical care will be included in the control group before the intervention is implemented, and 2500 patients in the case group after the implementation is effectuated. This study will evaluate the implementation process using baseline data on self-reported alcohol- and psychoactive medicine use, motivation to reduce consumption and mental distress. In addition, left-over blood samples used for diagnostic purposes will be collected and analyzed for alcohol, psychoactive medicinal and illicit drugs. After 12 months baseline data will be coupled to patient journal data and relevant registry data in order to evaluate the effects of the intervention.
This study is designed to examine the efficacy of a brief intervention plus a cognitive-behavioral intervention compared to brief intervention alone to address unhealthy alcohol use and comorbid mental health symptoms to improve HIV outcomes among people living with HIV in Alabama.
The purpose of this research study is to understand people's alcohol use in public places and their risks for harm. The overall goal of this study is to test the effects of subsidized ridesharing as an intervention to reduce self-reported alcohol-impaired driving, along with alcohol consumption and changes to mobility.
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).
This study is using functional magnetic resonance imaging (fMRI) to examine brain activity associated with making decisions about drinking alcohol in everyday situations, some of which may involve important activities happening the next day. The secondary aims are to determine whether severity of alcohol-related problems is related to brain activity and alcohol choices and to examine how different areas of the brain interact in connected networks.
