Filter by:Maternal smoking during pregnancy although it is known to be associated with fetal growth restriction, it's effect on postpartum breastfeeding is not yet clear. The aim of the present study was to examine the impacts of smoking in pregnancy on breastfeeding as well as its impacts on placental immunoreactivity.
This will be a single-center, single-blind, four-cohort, 22-day ambulatory study during which up to 24 healthy adult subjects [6 smokers (SMK), 6 moist snuff consumers (MSC), 6 vapers (VAP), and 6 non-tobacco consumers (NTC)] will complete 3 measurements of lung permeability. Nasal epithelial cells, sputum, and blood samples will also be collected for current and future biomarker research.
The purpose of this Actual Use Study (AUS) is to investigate how United States (US) adult tobacco consumers 21 to 60 years of age, inclusive, who are regular smokers (≥5 cigarettes/day on at least 20 of the past 30 days) will use the Cartridge-based ENDS investigational products (Study IP) over a 6-week Actual Use Period (AUP) in their real-life/naturalistic environments. Subjects will be able to choose freely among the Study IP available in one of the three study arms to which they are randomly assigned. The three study arms are organized by Study IP flavor categories: tobacco, menthol, and non-tobacco-non-menthol (NTNM). Subjects will self-report their ad libitum use of the Study IP as well as use of Combustible Cigarettes (CC) and any other tobacco- and nicotine-containing product (TNP) on a daily basis using an electronic diary (eDiary).
The purpose of this study is to describe the nicotine pharmacokinetic (PK) profile during and after single use of THS (Induction heating technology, with either a regular or menthol stick) compared to singular CIG smoking in healthy adult subjects. In addition, pharmacodynamic effects (subjective effects) will be evaluated to provide further insights on product acceptance and likelihood to use the THS again. Safety will be assessed throughout the study.
The investigators will conduct a message-exposure experiment with nationally representative samples of smokers, dual-users (cigarettes and e-cigarettes), and young adult non-smokers (aged 18-29). Experimental messages will address the reduction of nicotine in cigarettes. Participants will also complete a follow-up survey after 2 weeks, measuring their recall of the messages and behaviors since message exposure.
Periodontal diseases are among the major causes of tooth loss. Smoking may play a role as a contributing factor in the development of periodontitis by reducing the immune response. The role of cytokines in the pathogenesis of periodontal disease is clearly indicated in the literature; it has been shown that microorganisms that cause periodontal disease cause cytokine increase in saliva, gingival tissue and gingival crevicular fluid. Among these cytokines, interleukin (IL) -17 is proinflammatory and IL-35 is antiinflammatory and has been associated with periodontal disease.
This study is planned to determine the effect of online motivational interviews based on the transtheoretic model on the prediction of smoking cessation success, self-efficacy levels and smoking cessation behavior of pregnant women.It is an experimental research.
Among 10 PCPs, 200 adult smokers with an active patient portal who had been seen by a PCP within 12 months were randomly selected and randomly assigned to one of four conditions to compare the quit attempts of patients sent electronic outreach with and without asynchronous care link and to compare the quit attempts of patients who recieved the portal message from PCP or the health system.
Tobacco use disorder is a chronic disease. This is particularly true for people living with mental illness, who are more likely to smoke and make more unsuccessful quit attempts than those without. The current study is designed to test a package of two chronic disease management strategies to treatment tobacco in community mental health centers: regular provider interventions during routine mental healthcare visits, and proactive outreach by community mental health center staff to offer connections to tobacco cessation treatment. 50 patients at a community mental health center will receive provider intervention at their regular visits as well as 3 outreach calls over 9 months from trained staff to offer to connect them with stop smoking treatment. The investigators will measure the effect of these interventions on tobacco use over the next year.
The overall goal of this pilot study is to evaluate the feasibility of the Lumme smartphone app for smoking cessation in people living with HIV (PLWH) and evaluate its effect on smoking cessation. Mobile health (mHealth) technology can be used for achieving health equity in vulnerable groups because it is a widely available and relatively inexpensive tool for health behavior change and can be adapted to meet the needs of its end-users. Therefore, a mHealth intervention such as the Lumme App proposed through this study is timely, relevant, scalable and likely to improve health outcomes in PLWH who smoke.
