Filter by:This is a multi-center, open-label, parallel-cohort-study to evaluate the puffing patterns of healthy adult consumers of tobacco products switching from a usual brand (UB) combustible cigarette (CC) and/or a UB Heated Tobacco Product (HTP) to one of four investigational products (IPs), across two heating modes, over a 28-day ambulatory period.
This is a two-site, open-label, randomized, 6-way cross-over study designed to evaluate elements of abuse liability (AL) including subjective effects and physiological measures (pharmacodynamics [PD]) and plasma nicotine uptake (pharmacokinetics [PK]) during and following ad libitum use of the study investigational products (IPs) by generally healthy smokers.
This intervention study evaluates the effectiveness of a digital game intervention supporting smoking refusal self-efficacy among early adolescents (10-13 y). The participants are randomly allocated to two groups: the experimental group that receives the digital game intervention, and the control group that receives no intervention.
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.
The present study aimed to assess the effect of smoking on non-surgical periodontal treatment on serum and salivary RANKL, OPG and IL34 levels in periodontitis stage III grade C (P-III-C) patients. 20 periodontally healthy, 20 P-III-C and 20 P-III-C with smoking (P-III-CS) participants were enrolled. At baseline, serum and saliva samples were collected and the whole mouth clinical periodontal parameters were recorded. Periodontitis patients received non-surgical periodontal treatment. Clinical parameters were re-measured and samples were re-collected at 1 and 3 months after treatment. Serum and salivary RANKL, OPG and IL34 levels were analyzed by ELISA. Data were analyzed using appropriate statistical tests.
This is an open-label, randomized, 8-way crossover study designed to evaluate plasma nicotine pharmacokinetic (PK) parameters following an ad libitum use of Electronic Nicotine Delivery System (ENDS) investigational products (IPs) in a confinement setting by generally healthy combustible cigarette (CC) smokers and dual users of CC and ENDS.
This is a randomized, open-label, 6-way crossover, multi-site study designed to evaluate elements of abuse liability (AL) including subjective effects and physiological measures (pharmacodynamics [PD]), and nicotine uptake (pharmacokinetics [PK]) during and following ad libitum use of the Electronic Nicotine Delivery Systems (ENDS) investigational products (IPs) in generally healthy combustible cigarette (CC) smokers and dual users of CC and ENDS.
The purpose of this Actual Use Study (AUS) is to investigate how U.S. adult tobacco consumers 21-60 years of age) who are regular smokers (≥5 cigarettes/day) on at least 20 days out of the past 30 days will use P10 and P13 nicotine pouches (Study Investigational Product [IP]) over a 6-week Actual Use Period (AUP) in their real-life/naturalistic environment and in the context of typical consumer marketing materials. Subjects will self-report their ad libitum use of the Study IP as well as use of combustible cigarette (CC) and any other tobacco- or nicotine-containing product (TNP) on a daily basis using an electronic diary (eDiary). The study design is planned to address topics that FDA's Center for Tobacco Products (CTP) has identified as useful in evaluating new tobacco products.
Cigarette smoking is associated with surgical complications, including wound healing and surgical site infection. However, the association between smoking status and postoperative wound complications is not completely understood. Our objective is to investigate the effect of smoking on postoperative wound complications for major surgeries.
This is a randomized, controlled, multi-center, open-label, 8-cohort parallel group study to assess changes in select biomarkers of exposure (BoE) and biomarkers of potential harm (BoPH) in generally healthy smokers switching to the study investigational products (IPs), compared to subjects who continue to smoke, undergo smoking abstinence, or have never smoked.
