Summary

The proposed study is looking to recruit smokers over the age of 18 to complete a four visit study. Participants will be randomized to receive either rapamycin (sirolimus) or a placebo at the second visit to assess potential effects on craving and relapse. Four study visits will be completed over the course of about three weeks.

Summary

The purpose of this study is to develop repetitive transcranial magnetic stimulation (rTMS) as a potential treatment for nicotine addiction. Repetitive TMS is a non-invasive technique that uses magnetic pulses to temporarily stimulate specific brain areas in awake people (without the need for surgery, anesthetic, or other invasive procedures). This study will test whether rTMS over the forehead can produce a reduction in brain activity associated with craving that may prompt you to want to smoke cigarettes.

Summary

The purpose of this study is to develop theta burst transcranial magnetic stimulation (tbTMS) as a potential treatment for nicotine addiction. Theta burst TMS is a non-invasive technique that uses magnetic pulses to temporarily stimulate specific brain areas in awake people (without the need for surgery, anesthetic, or other invasive procedures). This study will test whether tbTMS over the forehead can produce a reduction in things that may prompt you to want to smoke cigarettes. TMS has been approved by the Food and Drug Administration as an investigational tool as well as a therapy for depression. However, TMS is not approved by the Food and Drug Administration as a treatment for nicotine cravings and other addictions.

This study consists of one consent session and one TMS session (can be on same day). Subjects will be asked to complete a series of questionnaires and computer assessments on how you think about nicotine and one session of TMS will be completed.

Summary

Current cigarette smokers (N=40) will sample three e-liquids within a single lab session, with different PG/VG ratios, complete a battery of questionnaires to assess sensory characteristics, product appeal, and reinforcement value. Participants will then complete a lab-based preference task to assess reinforcement value in which they choose between the three e-liquids. Finally, participants will receive one of the three e-liquids to take home for a one-week sampling period. During that week, we will assess e-cigarette and cigarette use. Participants will return the lab at the end of the week to complete additional questionnaires and return any unused product.

Summary

Cigarette smoking is a significant public health concern especially in cancer patients. rTMS has been investigated for smoking cessation in healthy smokers. This study will test the therapeutic benefits of rTMS for smoking cessation in cancer patients with smoking. Firstly, we will evaluate total number of smoke-free days during a 7-day quit attempt. Secondly, we will evaluate cigarette consumption and cue craving for smoking during the quit attempt period.

Targeting Foundational Memory Processes in Nicotine Addiction: A Translational Clinical Neuroscience Study of a Retrieval-Extinction Save

Summary

We recently published results from a NIDA-funded study of a brief behavioral treatment that was designed to reduce the troublesome cravings that smokers encounter when they attempt to quit smoking. This intervention was based on a growing body of neuroscience studies showing that memories for prior learning can be retrieved by the presentation of cues involved in that learning. Once retrieved, the memories enter into a brief period of vulnerability, during which they can be modified, but after which they are reconsolidated (restabilized) back into long-term storage. The treatment potential of this phenomenon was initially demonstrated in a Science report in which inpatient heroin addicts were briefly exposed to cues associated with heroin use in order to prompt the heroin use memories into a vulnerable state. Once the memories were in this state, the heroin addicts received extinction training consisting of protracted exposure to heroin associated cues. It was argued that extinction would change the memories such that the cues would no longer be associated with heroin administration and reward. Remarkably, after just two sessions of retrieval-extinction training (RET), the investigators found that craving in response to heroin cues was substantially reduced for up to 6-months post-treatment. This effect was observed relative to a control group that received retrieval involving non-heroin cues, followed by extinction. These impressive initial findings led us to replicate and extend the study in cigarette smokers. In our study, one group of smokers received two sessions of RET with smoking cues whereas a control group received the same training except that retrieval consisted of brief exposure to neutral, smoking-unrelated cues. Craving and other reactions to familiar and novel smoking cues were assessed in test sessions performed 24-hrs, 2-weeks and 1-month after intervention; smoking behavior was also assessed over 1-month follow-up. Remarkably, at 1-month follow-up, craving to both familiar and novel smoking cues was significantly lower in the group receiving R-E training vs. control. Even more striking was the 25% reduction in the number of cigarettes smoked per day in the RET group vs. control. [Also of significance was suggestive evidence that, relative to control participants, more participants in the RET group achieved a 60% reduction in smoking (from pretreatment levels)]. The proposed project will replicate and extend these findings by 1) increasing the dose of intervention so as to bolster the observed treatment effects, 2) employing brain imaging methods to identify patterns of brain activity uniquely associated with the intervention and potentially predictive of treatment outcome, 3) adding a control group that will enhance understanding of the effects of RET, and 4) extending follow-up period to more completely document the long-term effects of RET. Positive findings from this study could lead to the development of a brief, effective behavioral intervention to reduce the burden levied against society by smoking. Importantly, this intervention could be easily adapted to treat other forms of addiction and co-occurring anxiety disorders, such as PTSD.

Tobacco treatment in the context of lung cancer screening: NRT and text messaging Save

Summary

Screening for lung cancer at earlier, more treatable stages has the potential to reduce mortality from the U.S.'s most deadly cancer. Annual lung cancer screening with low-dose computed tomography is now recommended for high risk individuals based on age and smoking history. This study will evaluate a smoking cessation intervention for lung cancer screening patients. We will evaluate quit rates after a standard intervention (brief counseling session at time of LCS) versus a medication and text messaging intervention.

Summary

Emphysema is a type of Chronic Obstructive Pulmonary Disease (COPD) and a major cause of death. Studies suggest that emphysema is more common in HIV positive people (HIV+) compared to HIV negative (HIV-) people. The purpose of this research study is to determine whether emphysema in HIV+ patients is clinically and biologically different compared to emphysema in those without HIV.

The study involves use of a new quit-smoking smartphone application. Participants will use the app for two weeks, which involves completing surveys several times a day (approx. 15 min each) and logging any smoking activity. Participants will need to make a nicotine replacement medicine (over-the-counter and study provided) aided quit-attempt. Participants will have the opportunity to make suggestions that may improve the development of the app.
