There are 4 clinical trials
Background: - Drugs of abuse have effects on mood, behavior, thinking, and decision making that may encourage people to continue using them and make it difficult for them to stop. Researchers who study these effects are interested in developing new tests to evaluate how drugs and drug use affect different areas of the brain. - Magnetic resonance imaging (MRI) scans allow researchers to study brain activity and changes to brain function. When specific psychological tests are performed during functional MRI (fMRI) scans, researchers can examine the effects of drug use on the brain. By developing and testing new procedures for fMRI studies, more information can be obtained on brain function and activity in drug-using and non-drug-using individuals, and this information can help develop new treatments and therapies for substance abuse. Objectives: - To evaluate the effects of newly developed psychological procedures to be performed during fMRI scans. Eligibility: - Healthy volunteers between 13 and 55 years of age who are willing to undergo MRI scanning. - Both drug-using and non-drug-using individuals will be selected for this study. Design: - Before the start of the study, participants will complete questionnaires about medical and psychological history, and provide information about past or current drug use. Researchers will introduce the tasks to be performed during the scanning session(s), and will allow participants to practice the test either on a separate computer or on the computer used during the MRI scan. - During the study, participants will be asked to do one or more tasks selected by the researchers. The tasks will be performed on a computer in an MRI machine, and may involve receiving rewards (such as money or sips of juice) for actions, memory and reaction-time tests, or other tests that involve responding to instructions on the screen. - Participants will receive compensation for their participation in the study, including hourly compensation for individual visits and lump-sum compensation for each MRI scan.
Description: yield measurable and interpretable fMRI results, and/or if they are able to be combined with the application of tDCSMeasure: To determine if the tasks reliably and appropriately measure specific cognitive constructs and behaviors thought to be associated with specific brain systems and, also if they yield measurable and interpretable fMRI results. Time: each visit
Cigarette smoking constitutes the greatest preventable cause of mortality and morbidity in the US. The most critical period for long term success of smoking cessation appears to be in the first 7 days after the quit date. A metaanalysis of 3 pharmacotherapy trials revealed that abstinence during the first 7 days was the strongest predictor of 6 month outcomes (n=1649; Odds ratio: 1.4, P <0.0001; Ashare et al. 2013). Prodigious relapse rates during this first week of smoking cessation are likely due to behavioral and neurobiological factors that contribute to high cue-associated craving and low executive control over smoking. The long term goal of the research is to develop evidence-based transcranial magnetic stimulation protocols to facilitate abstinence during this critical period.
Description: The effect of real vs. sham iTBS to the left DLPFC vs. real vs. sham cTBS to the left MPFC as a tool to modulate the brain response to cigarette cravings will be assessed by comparing the brain activity in the executive circuit and limbic circuit before and after TMS. Participants will receive an MRI brain scan before their first TMS treatment, and at the end of their 10th days of TMS. At each MRI scan, participants will be subjected to a cigarette craving "cue" task within the scanner where elevated brain activity (BOLD signal) will be measured using an fMRI sequence. During each scan, they will see pictures of cigarette cues, neutral cues, and blurred images. The task is meant to induce craving and see how the brain responds to these craving cues.Measure: Neuroimaging outcomes: changes in drug cue reactivity as specified by changes in BOLD signal Time: Through study completion, an average of 8 weeks
Description: Participants will be asked to choose between two conditions in which varying amounts and delays to behavioral outcomes (e.g., $50 now or $100 later) are presented. We will use magnitudes of $100 and $1000 which are the most thoroughly documented among the literature. Across consecutive choices, the delay to the larger outcome will be titrated until reaching the participant's indifference delay (i.e., the delay at which s/he equally values both options). This indifference delay indexes individual participants' rates of delay discounting. Monetary delay discounting has been documented to be predictive to treatment success for smokers.Measure: Changes in Delayed Discounting Cognitive Behavioral Task Time: Through study completion, an average of 8 weeks
Description: This 10-item questionnaire assesses cigarette craving. Participants will be asked to rate from 1 (strongly disagree) to 100 (strongly agree) their agreement with several statements (e.g., "I have a desire for a cigarette right now," and "Nothing would be better than smoking a cigarette right now."). Factor analyses support two factors: one that reflects a strong desire and intention to smoke and one that reflects relief from negative affect associated with an urgent desire to smoke.Measure: Questionnaire on Smoking Urges administered daily both pre/post TMS to measure craving Time: Through study completion, an average of 8 weeks
Description: The hypothetical purchase task (HPT), a validated measure for cigarette demand, will assess cigarette purchases at various price conditions. Participants will hypothetically purchase quantities of cigarettes to use over a 24-hour period across ascending prices (e.g., $0, 0.12, $0.25, $0.50, $1.00, and $2.00 per cigarette). The HPT has been shown to be predictive of treatment outcomes. It will measure how participants value cigarettes throughout the course of the study visits.Measure: Hypothetical Purchase Task to measure tobacco product value and sensitivity Time: Through study completion, an average of 8 weeks
Description: Changes in cigarette use as detected by quantitative cotinine urine screens collected at visits 1, 6, 10, and all follow-upsMeasure: Biochemical assessment of tobacco use via quantitative urine screens to detect cotenine level Time: Through study completion, an average of 8 weeks
Description: This self-reported tobacco product use interview asks participants to retrospectively estimate the number of tobacco products they've used each day for the past 30 days or since the previous assessment, whichever is fewer.Measure: Self- report assessment of tobacco use through Timeline Follow-Back (TLFB) Interview Time: Through study completion, an average of 8 weeks
Description: Breath CO provides an accurate measure of recent exposure to CO, including from smoking combustible tobacco products (95). The CO measurement will be used to determine recency of smoking.Measure: Biochemical assessment of recent tobacco use via breath Carbon Monoxide (CO) sample Time: Through study completion, an average of 8 weeks

This cohort study will obtain electronic health record (EHR) de-identified data from 21 health systems affiliated with the Cancer Center Cessation Initiative (C3I) network or health systems with large numbers of COVID-19 patients to explore whether smoking status, cancer history, and other risk factors among patients diagnosed with COVID-19 are associated with mortality and/or COVID-19 disease severity/complications. Each site will provide de-identified data from their health system EHR on a monthly basis that includes all patients identified as having COVID-19 at some point in the interval from February 1, 2020, through December 31, 2020.
