Filter by:This study will investigate the effect of four tax proposals (i.e. Tobacco Parity, Nicotine-Content, Harm-Reduction, and Modified Risk Tobacco Product-related taxes) on tobacco product purchasing patterns.
The proposed study will evaluate sex differences in whole-brain glutamate (Glu), with a focus on the dorsal anterior cingulate cortex (dACC), anterior insula, and thalamus, as well as how it is influenced by sex (males vs. females), smoking state (overnight abstinent vs. sated), and circulating ovarian hormones (estrogen and progesterone) in women. Glu will be measured in almost the entire brain, with special focus on the dorsal anterior cingulate cortex (dACC), anterior insula, and thalamus, all of which have been implicated in behavioral states linked to tobacco withdrawal, using an echo-planar spectroscopic imaging (EPSI) variant of magnetic resonance spectroscopy (MRS). Serum ovarian hormones (estrogen and progesterone) will be measured for female participants to determine relationships between brain Glu and this hormone. Whole-brain Glu will be measured in 60 smokers (30 men, 30 women) twice, after overnight (~12 h) abstinence and after participants smoke the first cigarette of the day.
Smoking is the main cause of preventable disease and death in the US and impacts respiratory illnesses including COPD and asthma. However, little is known about the effects on smoking and lung health of substituting cigarettes with ENDS in adults with asthma. This project aims to test whether providing ENDS to adults with asthma will lead to substitution of smoking for ENDS, reduced dependence, and improved lung function so such knowledge can inform interventions to reduce the public health burden of tobacco.
The parent project (1R21CA253600-01, R21 phase: 9/1/2020-8/31/2022, R33 phase: 9/1/2022-8/31/2025) aims to adapt and evaluate the efficacy of our theoretically and empirically based mobile health (mHealth) technology to help general patients in Lao People's Democratic Republic (Lao PDR) quit smoking cigarettes. This mHealth automated treatment (AT) approach includes a fully automated, interactive, personalized, smartphone-based intervention for behavioral treatment, delivered through our Insight platform. The purpose of this projects to expand our mHealth-based intervention to address the pressing need for smoking cessation among cancer survivors and their caregivers in Lao PDR. In this project, the investigators will further adapt the AT intervention to ensure that its content is comprehensible and relevant to the target populations (i.e., cancer survivors and caregivers). Then, the investigators will conduct a pilot randomized controlled trial (RCT, N=80) to evaluate the preliminary efficacy of the intervention. Cancer survivors (n=40) and caregivers (n=40) of both sexes who smoke will be identified via medical records at the Setthathirath Hospital (SH) and Lao National Cancer Center (LNCC) and recruited. Similar to the parent project's design, participants will be randomized to 1 of 2 treatment groups: standard care (SC) or AT (20 cancer survivors and 20 caregivers in each group). SC consists of brief advice to quit smoking delivered by research staff, self-help written materials, and a 2-week supply of nicotine patches. AT consists of all SC components plus our fully-automated interactive smartphone-based treatment program, personalized and tailored to cancer survivors or caregivers. The primary RCT outcome is biochemically confirmed self-reported 7-day point prevalence abstinence at 3 months post-study enrollment. The specific aims are as follows: Aim 1: Evaluate the feasibility of AT in cancer survivors and caregivers. Hypothesis (H1): ≥75% of AT content will be viewed/opened as indicated by digital date/time stamp in Insight. Aim 2: Evaluate the preliminary efficacy of AT in each cancer survivor/caregiver subgroup. Hypothesis (H2): At the 12-week follow-up, 7-day point prevalence abstinence will be higher in the AT (vs. SC) group.
In Lao People's Democratic Republic (Lao PDR), 51% of adult men and 7% of adult women smoke tobacco. The development and evaluation of sustainable tobacco cessation interventions suitable for widespread adoption in nations such as Lao PDR are pressing public health needs. To address this need, the investigators propose a project that adapts a theoretically and empirically based mobile health (mHealth) technology to help people quit smoking cigarettes in Lao PDR. This mHealth approach includes a fully automated, interactive, personalized, smartphone-delivered intervention for behavioral treatment, delivered through our Insightâ„¢ platform. This proposed project for Lao PDR includes 2 main phases. In the R21 Phase, the investigators will use formative research methods to adapt our intervention content to the sociocultural context, language, and communication styles of Laotians. In the subsequent R33 Phase, the investigators will conduct a randomized controlled trial (RCT) to evaluate the efficacy of our mHealth intervention and technology. Adult smokers of both sexes will be recruited through 2 large hospitals: Setthathirath Hospital in Vientiane and Champasak Hospital in Champasak Province. Participants (n=500) will be randomized to 1 of 2 treatment groups: Standard Care (SC; n=250) or Automated Treatment (AT; n=250). SC consists of brief advice to quit smoking delivered by research staff, self-help written materials, and a 2-week supply of NRT (transdermal patches). AT consists of all SC components plus a fully automated smartphone-based treatment program that involves interactive and personalized proactive messages, images, or videos. The primary health outcome of the trial is biochemically confirmed self-reported 7-day point prevalence abstinence 12 months post study enrollment. The project also aims to advance mHealth research capacity in Lao PDR and sustain the US-Lao PDR research network. The project has the potential to transform healthcare services for tobacco cessation treatment throughout the country and, ultimately, to reduce tobacco-induced morbidity and mortality significantly.
This study is a randomized community-based trial adapted to the needs of adults aged 21 years or older that is designed by an existing research partnership called Communities Engaged and Advocating for Smoke-free Environments (CEASE). The overarching goal of the proposed study is to apply a community-based approach to reduce tobacco use among low-income communities in Baltimore City. The study setting represents three underserved communities in Baltimore City: the Oldtown/Middle East, the Waverlies, Poppleton/The Terraces/Hollins Market, and Washington Village/Pigtown. Poppleton/The Terraces/Hollins Market and Washington Village/Pigtown will be considered as one community. The three communities have been randomly allocated to one of the three arms of the study: 1) Virtual intervention, 2) Enhanced in-person intervention, and 3) The control community. The Waverlies was assigned to virtual, the Middle East was assigned to be the in-person group, and Poppleton/The Terraces/Hollins Market and Washington Village/Pigtown became the self-help/control group. The goal of the trial is to assess the effectiveness of virtual versus in-person versions of a smoking cessation program in terms of their success rates (quitting and staying quit). The study's primary hypothesis is that the smoking cessation rate will be equal to or higher in the virtual peer-motivation arm than the in-person and self-help/ control arms. The secondary hypothesis is that the retention rate will differ among the three interventions (virtual peer-motivation, enhanced in-person peer-motivation, and self-help/control community). Virtual and enhanced in-person versions of the CEASE Today Peer-Motivation Intervention were developed and pilot-tested during the first and second years based on local data and input from partnering communities. The enhanced in-person intervention will utilize the existing CEASE Today Tobacco Cessation Manual with improvements. The virtual intervention will use a newly developed CEASE website with smoking cessation modules and lessons that mirror the CEASE Today Tobacco Cessation Manual. Trained peer-motivators will deliver the intervention and be actively involved in recruiting the participants, motivation enhancement, group facilitation, and counseling.
This study will investigate the relative appeal (abuse liability) of novel tobacco products, how the appeal is modulated by relative price, user type, and how novel products may substitute for one another.
Periodontitis patients, 40 cigarette smokers and 40 non-smokers (defined by cotinine measures in serum), were recruited to this double arm prospective cohort study. Data were collected 3 months following non-surgical and surgical periodontal treatment, and following 12 months with supportive periodontal therapy. Data collected were clinical attachment level, probing depth, bleeding on probing,oral bacteria, serum, blood (PAXgeneBlood), and gingival crevicular fluid.
The present study will investigate the effects of choice bundling, in which a single choice produces a series of repeating consequences, on valuation of delayed monetary gains and losses in an online panel of cigarette smokers.
The purpose of this study is to examine the effect of nicotine messaging and nicotine content of study cigarettes on nicotine beliefs and subsequent use of tobacco and nicotine products.
