CSD231005 Nicotine Pouch Biomarkers of Exposure

Start date: July 15, 2024
Phase: N/A
Study type: Interventional

This will be a multi center open label, randomized, controlled, switching parallel-group study designed to assess changes in select biomarkers of exposure (BoE) in generally healthy smokers following a 5 day in-clinic switch to use of nicotine Pouch investigational products (IPs) compared to continued usual brand (UB) cigarette smoking or smoking abstinence.

NCT ID: NCT06291558 Recruiting - Depression Clinical Trials

Exercise Training for Smoking Students

Start date: October 1, 2023
Phase: N/A
Study type: Interventional

Smoking can damage lung functions as a result of high carbon monoxide and low hemoglobin oxygen carrying capacity in the blood. Smoking between young people continues to increase, which can cause respiratory function problems and lung diseases at an early age. In the studies, it has been seen that smoking may reduce the oppression and exercise ability.

NCT ID: NCT06277271 Recruiting - Smoking Clinical Trials

E-cigarettes as a Harm Reduction Strategy

Start date: June 20, 2023
Phase: N/A
Study type: Interventional

E-cigarettes have emerged as an effective strategy for replacing cigarettes among smokers from the general population, but there is a dearth of studies investigating their utility in replacing cigarettes among smokers with opioid use disorder (OUD). This study aims to evaluate the feasibility and acceptability of implementing a cigarette harm reduction intervention involving e-cigarettes in office-based buprenorphine clinics.

NCT ID: NCT06264154 Not yet recruiting - Smoking Clinical Trials

The Role of Flavor in the Substitutability of E-cigarettes for Combustible Cigarettes Among Persistent Smokers

Start date: April 2024
Phase: N/A
Study type: Interventional

This between-subjects study aims to evaluate the effect of flavor on initial and sustained switching from combustible cigarettes to e-cigarettes among 210 cigarette smokers. After measuring baseline cigarette smoking rate, participants will be randomized to a six-week regimen of fruit-flavored, tobacco-flavored, or menthol-flavored e-cigarettes and be instructed to switch (versus smoking cigarettes) over a 6-week period. Flavor-associated subjective reward and the reinforcing value of flavored e-cigarettes relative to combustible cigarettes will be assessed as mechanisms.

NCT ID: NCT06228976 Recruiting - Smoking Cessation Clinical Trials

Mindfulness-based, Mobile Health (mHealth) Smoking Cessation Intervention in Vietnam

Start date: August 27, 2023
Phase: N/A
Study type: Interventional

The goals of this a three-arm randomized controlled trial (RCT) is to evaluate the efficacy of mindfulness-based, culturally appropriate, and mobile phone-based smoking cessation intervention among Vietnamese adult male smokers. The intervention will be delivered via text messages, involving 1,200 adult male smokers, with 400 participants in each of three intervention arms (Cessation Intervention - culturally-adapted smoking cessation messages that incorporate mindfulness; Education Intervention - messages that solely focus on health risks of smoking; Control - basic messages that solely focus on general healthy lifestyle). The investigator will assess cessation rates up to 6-month follow-up, as well as secondary outcomes of knowledge of smoking health risks; stages of change; quit attempts; self-efficacy; cigarettes per day; and nicotine dependence. The investigators hypothesize that participants in the Cessation Intervention group (who will receive culturally-adapted messages) will have higher rates of smoking abstinence, greater knowledge of the health risks of smoking, more transitions from pre-contemplation/contemplation stages to planning/action stages, higher likelihood of making a quit attempt, higher self-efficacy for abstaining from smoking, greater reductions in cigarette consumption, and lower nicotine dependence, compared to participants in the Education Intervention group and Control group.

NCT ID: NCT06191497 Active, not recruiting - Smoking Clinical Trials

The Effect of Smoking and Chlorhexidine on Periodontal Tissues After Non- Surgical Periodontal Therapy in Patients With Periodontitis

Start date: March 14, 2022
Phase: N/A
Study type: Interventional

The aim of this study is to evaluate whether the use of a chlorhexidine based oral antiseptic will improve clinical results of non-surgical periodontal therapy (NSPT) in smokers with periodontitis. A randomized controlled clinical trial will be carried out on 60 subjects with periodontitis- 30 smokers and 30 non-smokers. All subjects will be clinically examined. The following periodontal indices will be measured: Full mouth plaque score (FMPS), Full mouth bleeding score (FMBS), Pocket probing depth (PPD), Clinical attachment level (CAL), Gingival recession (GR) and Tooth mobility (TM). All subjects will have NSPT carried out. Half of the subjects in each group will use a 0.12% chlorhexidine based mouth rinse twice a day during 15 days. Clinical examination will be repeated 8 weeks after NSPT and compared.

NCT ID: NCT06105424 Completed - Smoking Clinical Trials

BRP1602: Evaluation of Technical and Logistical Feasibility to Measure Lung Permeability

Start date: September 24, 2016
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT06103578 Completed - Smoking Clinical Trials

Evaluation of SOST, TWEAK, RANKL, OPG Levels in Smokers and Non-Smokers With Periodontitis

Start date: December 1, 2021
Phase:
Study type: Observational [Patient Registry]

Periodontitis is a chronic inflammatory disease with multifactorial etiology. Although periodontal disease is initiated by pathogens within the biofilm layer, disease development and tissue destruction occur as a result of the interaction of periodontal pathogens and the host immune response. It has been determined in the literature that smoking has a significant negative effect on periodontal tissues and increases the risk of periodontitis by 2-5 times. It has been shown that there is a relationship between smoking and the incidence and progression of periodontitis. However, the mechanisms by which this occurs have not been explained. In this study, the effect of smoking on the levels of sclerostin (SOST), tumor necrosis factor-like weak inducer of apoptosis (TWEAK), receptor activator of nuclear factor-kB ligand (RANKL), and osteoprotegerin (OPG), which are effective in bone metabolism, in gingival crevicular fluid (GCF) and saliva will be evaluated. Participants in the study were in accordance with the 2017 World Workshop on Classification of Periodontal and Peri-implant Diseases and Conditions criteria as a result of clinical evaluations systemically healthy, non-smokers diagnosed with stage 2, 3 and/or 4 periodontitis (Group 1) (n=26); systemically healthy, diagnosed with stage 2, 3 and/or 4 periodontitis and smokers (Group 2) (n=26); systemically and periodontally healthy, non-smokers (Group 3-Control Group) (n=26). Clinical periodontal indixes will be obtained from participants meeting the inclusion criteria; GCF and saliva samples will be collected. The samples will be examined by ELISA test at Gazi University Faculty of Medicine, Department of Immunology.

NCT ID: NCT06095999 Recruiting - Smoking Clinical Trials

Perfect Fit: Evaluation of a Virtual Coach for Smoking Cessation and Physical Activity

Start date: September 19, 2023
Phase: N/A
Study type: Interventional

The leading cause of disease burden across the globe is cardiovascular disease (CVD). Important modifiable behavioral CVD risk factors include, amongst others, smoking and low physical activity (PA). Individuals with a low socioeconomic position (SEP) often have a less favorable profile of risk factors, resulting in a higher disease burden and premature death. There is a need for cost-effective multi-behavior interventions that target one or more risk factors. eHealth applications are increasingly being used to offer behavior change interventions. Potential benefits include accessibility, scalability, cost-effectiveness, and increased disease self-management. However, eHealth interventions are often static and thereby less effective, and also frequently developed without (sufficiently) engaging end-users. Involving end-users, including those from lower SEP groups, and other relevant stakeholders can help to optimize the adoption and adherence to the eHealth intervention and result in the maintenance of healthy behavior. The Perfect Fit intervention is the result of interdisciplinary collaboration, and the personalized eHealth intervention supports adult smokers to stop smoking and increase their PA using a virtual coach. We primarily aim to examine the feasibility, acceptability and preliminary effectiveness of the Perfect Fit intervention. A mixed-method single-arm pre-post intervention study will be used. The intervention, delivered through a virtual coach, has a personalized duration and intensity, but will last on average 16 weeks.
