Filter by:This project aims to demonstrate the feasibility of a scalable behavioral intervention using smartphone-paired breathalyzers and text message aimed at reducing drinking and driving among individuals who report heavy drinking. All participants receive a smartphone breathalyzer to provide feedback on their estimated blood alcohol level. The intervention compares loss- and gain-framed messages that make the consequences of drinking and driving more salient to standard messages not to drink and drive.
This study is designed to test LabPatch-alcohol, a wearable, non-invasive biosensor Band-Aid like patch that is designed to detect real-time changes in interstitial alcohol concentrations in human subjects. The changes in interstitial alcohol concentrations will be compared to blood alcohol concentrations to determine the patch's validity against the gold standard.
Alcohol use disorder (AUD) impacts millions of Americans and is associated with significant behavioral, social, economic, medical, and neurobiological dysfunction, yet current behavioral treatments for AUD are only modestly effective. The proposed research will test the efficacy of a novel behavioral intervention, which combines brain stimulation with mindfulness-based relapse prevention, and is hypothesized to improve neural dysfunction and ultimately lead to large effect size reductions in heavy drinking among individuals with AUD. Given that mindfulness and brain stimulation are already available for "home use" there is great potential for the ultimate dissemination of the intervention on a large scale, which could have a significant impact on public health.
This will be a prospective survey study. The participants will all be volunteers of legal drinking age. Each participant will consume one alcoholic beverage (beer) at a time and then will be asked to verbally estimate their current blood alcohol concentration and if the subject feels they are able to drive. At that time, their BAC level will be measured objectively using a breath alcohol test (BAT) device. The participant will not be told their objective value. This will continue with a verbal estimate and actual BAT reading after every drink until the participant reaches a minimum BAC of 0.10. At this time, participants will continue to be monitored until their BAC falls to 0.08 and they are clinically sober. As their blood alcohol level decreases, the investigators will ask the participant to estimate their level every hour along with an actual reading until reaching 0.08. Statistical analyses will be used to determine how accurate self estimation is in regards to blood alcohol content.
This is a prospective cohort study. The investigators will enroll 50 healthy volunteers. In a safe environment and after signing informed consent, each participant will consume a standardized alcoholic beverage. Using a Breathalyzer, the subjects BAT will be measured. If the subject's BAT is less than 0.10 +/- 0.005, the subject will drink another alcoholic beverage. This process will continue until the subject's BAT is 0.10 +/- 0.005. The number of alcoholic beverages the subject consumes will be monitored by the observers. When the target BAT is reached, the subjects will manipulate the breathalyzer in various ways and measure their BAT again after each manipulation. In a set order, the subjects will manipulate the breathalyzer by using less than the subject's maximal exhalation effort, placing the breathalyzer at the side of the subject's mouth, hyperventilating (10 rapidly (less than 1 second) and successive breaths prior to using the device), repeating breathalyzer 5 minutes and 10 minutes after hyperventilation and then drinking cold water after the breathalyzer at 10 minutes and repeating the breathalyzer after drinking some cold water. Descriptive statistical analyses as well as Pearson's product moment correlation coefficient will be employed to determine if any statistically significant correlation exists for any of the manipulations.
This study is intended to evaluate the prevalence of chronically inebriated patients in the Emergeny Department (ED). Patients will be identified prospectively by screening all patients (24/7) presenting to the ED for one month. A running tally of all patients in the ED will be kept. Of these patients, any patient that is noted to have alcohol intoxication will be identified. The chart of that patient will be reviewed for details about the patient's alcohol use and for the patient's suitability for a sobering house, which is a place where intoxicated patients can go to await sobriety. The chart will also be reviewed for the number of previous visits for alcohol use to our hospital ever and in the last year.
Investigators aim to test the effectiveness of a text-message-based behaivoral intervention in reducing binge drinking among young adults.
1. The major aims are to assess: (1) the relationship of basal and alcohol-induced neurosteroid and GABA levels to the degree of acute alcohol intoxication in healthy male and female volunteers; and (2) the effect of acute pregnenolone administration on the degree of acute alcohol intoxication in these same volunteers. Specific hypotheses are: - Baseline serum levels of pregnenolone, pregnenolone sulfate (PS), dehydroepiandrosterone (DHEA) and DHEA sulfate (DHEA-S) will be inversely correlated with the magnitude of acute behavioral responses to alcohol (sedation, anxiolysis, amnesia, psychomotor impairment and intoxication). That is, higher baseline levels of these neurosteroids will be associated with lessened behavioral responses to alcohol. - Baseline serum levels of allopregnanolone, tetrahydrodeoxycorticosterone (THDOC), androstanediol, androsterone and GABA will be directly correlated with the magnitude of acute behavioral responses to alcohol. That is, higher baseline levels of these substances will be associated with heightened behavioral responses to alcohol. - Acute alcohol ingestion, compared to placebo ingestion, will increase serum levels of allopregnanolone and THDOC and plasma levels of GABA and will decrease plasma levels of PS. (Effects on levels of other neurosteroids are not specifically predicted based on animal data but will be examined in an exploratory manner.) - Acute alcohol-induced increases in serum levels of allopregnanolone and THDOC and in plasma levels of GABA will be directly correlated with the magnitude of acute behavioral responses to alcohol. Acute alcohol-induced decreases in serum levels of PS will be directly correlated with the magnitude of acute behavioral responses to alcohol. Correlations between alcohol-induced changes in other neurosteroids and changes in behavior are not specifically predicted but will be examined in an exploratory manner. - Pregnenolone, compared to placebo, pre-treatment will antagonize the acute effects of alcohol on the behavioral measures.
The aim of this study is to develop information about the acute and residual effects of a new product being targeted to young adults. Using a double placebo-controlled 2 X 2 factorial model study design, we will compare the acute and residual effects on driving impairment of caffeinated alcohol, non-caffeinated alcohol, caffeinated placebo, and non-caffeinated placebo. Under the alcohol conditions, participants will receive sufficient alcoholic beverage to attain a blood alcohol concentration (BAC) of .12 g%. Participants will be 144 undergraduate and graduate students, and recent college graduates.
