Filter by:The overarching goal of this translational proposal is to determine if neuroactive flavor chemicals can enhance the addiction potential of electronic nicotine delivery systems (ENDS) by altering brain function and behavior.
This is a multi-arm, randomized controlled, pilot study which will recruit cancer patients who have been seen by a UCSF Cancer Center-affiliated clinical department to evaluate the efficacy of "CareConnect". This is the first study to assess the efficacy CareConnect, a combination of the Ask-Advise-Connect (AAC) with an Interactive Voice Response (IVR) delivering cancer-targeted educational messages to support referral to smoking cessation resources for patients with cancer.
This proposal tests the efficacy of a phone-based tobacco cessation intervention for people living with HIV (PLWH) in comparison to the standard of care (brief advice to quit) and nicotine replacement therapy (nicotine patches) in Uganda and Zambia. This study will provide insight into the efficacy, feasibility, applicability, and affordability of delivering tobacco cessation interventions through health care professionals at HIV treatment centers in two countries with different tobacco use patterns, policy environments, and health care resources. The previously tested SMS-platform to be used in this study is uniquely positioned to be scaled in low- and middle-income countries worldwide, in which case rigorous research showing even modest success in reducing the prevalence of tobacco consumption among PLWH could confer substantial health and economic benefits.
Cannabidiol is a compound found in cannabis plants that is well tolerated, has low abuse liability, and might be an effective medication to promote tobacco cessation. This clinical study will use a validated approach for screening tobacco cessation medications to determine if oral cannabidiol increases short-term tobacco abstinence, and evaluate mechanisms that might explain how cannabidiol alters smoking behavior. Results from this study will provide data on the therapeutic potential of cannabidiol for tobacco cessation.
The long-term goal of FRESH Delivers is to fill a critical gap in knowledge on the role of a home-based food delivery social intervention in the elimination of tobacco-caused cancer health disparities. The central hypothesis is that smokers who receive real-time video-based motivational counseling and home-based food deliveries will have greater cotinine-verified 7-day point prevalence abstinence than those who receive real-time video-based motivational counseling alone or home food delivery alone. The rationale for this approach is that studies show increased odds of smoking cessation with increasing food security.
The present study is a 3-arm randomized controlled pilot study. Participants who call the Maryland Tobacco Quitline and are eligible for study participation are randomized to receive quitline tobacco cessation treatment as usual (TAU), TAU plus remote carbon monoxide (CO) monitoring via smartphone app, or TAU plus remote carbon monoxide monitoring plus incentives vis smartphone app. We hypothesize that remote CO monitoring will be feasible and acceptable to deliver in the quitline setting, will increase treatment engagement, and will increase tobacco cessation and treatment satisfaction rates.
The proposed pilot study aims to develop and test a patient video educational tool, an interactive Mobile Doctor (iMD), that can be integrated in radiation oncology setting to effectively engage cancer patients receiving treatment at University of California, San Francisco (UCSF) to facilitate smoking cessation and maintaining smoking abstinence in the context of their radiation treatment. This study is the first to address tobacco use among can patients receiving radiation therapy that targets both tobacco cessation (current users) and maintaining abstinence (former users who have recently quit).
This randomized controlled trial will test whether adding biomarker measurement and informed outreach for tobacco smoke exposure as part of routine practice increases identification and improves treatment, effectiveness, and sustainability of a parental tobacco control intervention that will be integrated into pediatric practice.
Tobacco smoking is a major health problem, leading to considerable morbidity and mortality due to cancer, impaired pulmonary function, and cardiovascular diseases. Chronic nicotine consumption related to smoking may affect pulmonary function and can cause neuronal alterations leading to increased emotional distress and decreased cognitive functioning, especially when the smoker attempts to quit. These may explain the huge difficulty in quitting and the dependence on cigarettes as a means of maintaining emotional balance. The possibility that reduced sleep quality is a major negative outcome that contributes to nicotine addiction has been largely overlooked. Several studies have shown that smoking and smoking cessation disrupt sleep quality; however, the vast majority of these studies were based on subjective reports. Moreover, it is not clear to what degree disrupted sleep quality among smokers may be related to reduced pulmonary function, and to what degree reduced sleep quality contributes to the emotional cognitive distress of active and abstinent smokers and to their urge to smoke. The main hypothesis of this proposal is that smoking and early phases of smoking cessation will be associated with reduced sleep quality. This poor sleep quality will be associated with emotional and cognitive symptoms and difficulty in abstaining from tobacco smoking. Successful abstinence from smoking over time will lead to normalization of the quality of sleep. Experiments to investigate this hypothesis will be conducted on healthy young adults addressing the following specific aims: 1) To examine physiological and psychological factors predicting reduced quality of sleep among smokers, including: poor pulmonary function, the degree of nicotine dependence, altered regulation of stress systems (HPA axis and the sympathetic nervous system), and emotional distress (anxiety and depression); 2) To explore the impact of smoking cessation on sleep quality and related symptoms. Specifically, whether smoking cessation induces fragmented sleep and poor sleep quality, and whether the diminished sleep quality can predict the magnitude of emotional and cognitive symptoms; 3) To examine whether poor sleep (before and during abstinence) can predict the level of the urge to smoke and smoking relapse among abstinent smokers; 4) To explore whether sleep quality ultimately improves following prolonged abstinence from smoking. Addressing these aims, nonsmokers and smokers will be examined before and during smoking abstinence on the following measures: quality of sleep via actigraphy and polysomnography (PSG), pulmonary function test, biological markers of stress (cortisol and α-amylase) and smoking (i.e., cotinine, the main metabolite of nicotine), and emotional and cognitive functioning via psychometric tests. Results of this study will provide novel insight on the role of sleep in nicotine addiction. Experiments will show how reduced quality of sleep may result from chronic smoking and interfere with attempts to quit smoking. Also, the experiment will shed light on the interrelated physiological and psychological mechanisms that mediate the interplay between smoking addiction and sleep. The research will utilize a variety of powerful methods and an interdisciplinary collaboration of experts in the fields of sleep, addiction, and pulmonary medicine. It is anticipated that the results will contribute substantially to our knowledge of smoking addiction and may promote the development of effective therapeutic interventions to this major public health problem.
This study will evaluate a reward devaluation strategy in which smokers use the JUUL e-cigarette immediately before any combustible cigarettes (CCs) are smoked. This procedure is predicted to accomplish three goals: 1) the rewarding effects of CC will be disrupted because subjects will already have attained fairly high peak nicotine concentrations immediately before smoking the cigarette. This reduces the rewarding effect of smoking, in part from receptor desensitization that occurs following nicotine exposure, which reduces the response to a subsequent dose of nicotine, and in part from satiating the drive to smoke; 2) the use of the JUUL will become associated with the same cues that elicit smoking, thereby promoting the substitution of JUUL use for CC use; and 3) ad libitum nicotine intake from the JUUL and its rewarding effects will be maximized because, unlike CC, they will be experienced after a period of nicotine deprivation. Thus, despite a lower per-puff nicotine dose relative to CC, the pharmacologic impact and reinforcing effect will be maximized. The study will evaluate two flavors (Mint and Virginia Tobacco), randomly assigned, to determine if flavor assignment (similar to the subjects' usual brand of CC or different than the subjects usual brand CC) has an effect on the success of this reconditioning procedure.
