This study was an internal program effectiveness evaluation of the effects of a four-session weekly individualized cognitive therapy program (called the "Mind Freedom Plan" (MFP)) on substance use outcomes and substance abuse treatment retention in Veterans admitted to an intensive outpatient treatment program for substance abuse at the Richmond Veterans Administration Medical Center (RICVAMC). Substance use and treatment retention metrics of MFP-assigned Veterans were compared with those of Veterans assigned to typical case-management-oriented weekly individual sessions.
High relapse rates among substance dependent individuals are likely due to a combination of factors that involve limbic circuits in the brain involved in craving, including vulnerability to salient cues. Emerging data suggests that non-invasive, targeted brain stimulation may be able to modulate activity in these circuits and decrease craving. The primary goal of this pilot study is to determine the extent to which a single session of continuous theta burst stimulation to the medial prefrontal cortex can attenuate limbic circuitry involved in craving among cocaine users and alcohol users. This will be tested through a double-blind,sham-controlled brain stimulation and brain imaging study in a cohort of polysubstance abusers and alcohol users.
The overall objective of this study is to extend previous work in the development of methods to automatically detect the timing of cocaine use from cardiac interbeat interval and physical activity data derived from wearable, unobtrusive mobile sensor technologies. The specific objectives of this protocol are to characterize under which conditions high quality continuous interbeat interval data and physical activity data can be obtained from a specially developed smartwatch device in the natural field setting among a population of cocaine users. In addition to identifying common failure scenarios and understanding wearability/usage patterns when collecting interbeat interval from smartwatches, this study will extend previous work in the detection of cocaine use via interbeat interval and physical activity data that were previously obtained from wearable chestband sensors. Information from this study will contribute toward the adaptation of the investigators' existing computational model for detecting cocaine use via the chest sensors, so it can be applied to the interbeat and physical activity data obtained from less obtrusive smartwatches.
Qualitative project, comprising open-ended semi-structured interviews with healthcare workers, who provide antenatal care to substance-using women.
The purpose of this research study is to determine whether a medication called pioglitazone (trade name Actos) can reduce behavioral problems associated with cocaine use, improve brain structural changes associated with cocaine use and reduce cocaine craving and drug use in cocaine dependent patients.
The pharmacokinetics of 10 to 12 individuals receiving 60 mg of sustained release dexamphetamine will be studied. These individuals have received this medication before in a previous trial where the pharmacodynamics were investigated. This trial will last 5 consecutive days during which blood samples will be drawn for pharmacokinetics analyses. Dried blood spots will also be collected for the clinical validation of the bioanalytical method wherein these are used.
This study aims at testing for the impact of glutamatergic changes on drug craving in cocaine addiction, and to evaluate the effects of n-acetylcysteine (n-AC) on both glutamate homeostasis and craving using a randomized, double-blind, placebo controlled cross-over design.
Repeated drug consumption may progress to problematic use by triggering neuroplastic adaptations that attenuate sensitivity to natural rewards while increasing reactivity to craving and drug cues. Converging evidence suggests that glutamate modulation may work to correct these adaptations and rapidly restore motivation for delayed non-drug rewards relative to immediate drug use. Using an established laboratory model aimed at evaluating behavioral shifts in the salience of cocaine now vs. money later, the investigators will test the effect of CI-581a on cocaine self-administration as compared to the active control.
The main purpose of this study is to determine if it is safe to use the study drug, clavulanic acid, in combination with cocaine. In this study, subjects will receive intravenous (i.v.) cocaine and the study drug, clavulanic acid. The safety of clavulanic acid is being studied so future studies can be done to find out if this drug is helpful in treating cocaine dependence. Currently, there is no available medication treatment for cocaine dependence.
The primary objective of this study is to determine if there are significant interactions between oral lorcaserin treatment concurrent with 20 and 40 mg intravenous (i.v.) cocaine infusions by measuring adverse events (AEs) and cardiovascular responses including heart rate (HR), blood pressure (BP), and electrocardiogram (ECG) (including QTc).
