Filter by:This study is focused on characterizing the toxic and carcinogenic potential of the Standardized Research E-cigarette (SREC) developed by the National Institute on Drug Abuse. In the environment of continuously changing e-cigarette market, SREC was developed as a model e-cigarette that will remain available for an extended period of time and can be used as a bridging element in various studies aimed at evaluating the value and limitations of e-cigarettes as tobacco risk reduction tools. Our overall goal is to generate initial reference data on chemical exposures and associated effects in smokers switching to SREC.
Smokers living with HIV represent a major health disparity population in the United States and the world more generally. Major contributing factors to the maintenance and relapse of smoking among smokers living with HIV include increased exposure to multiple stressors associated with HIV, which often exacerbates anxiety/depression. In a previous project, the feasibility, acceptability, and initial efficacy of a 9-session, cognitive-behavioral-based intervention to address smoking cessation by reducing anxiety and depression via specific emotional vulnerabilities (anxiety sensitivity, distress tolerance, and anhedonia) was tested against an enhanced standard of care in a pilot randomized controlled trial (NCT01393301). It was found that when compared to a brief enhanced treatment as usual control, patients in the intervention achieved higher short-term and long-term smoking abstinence rates. In this project, the investigators seek to test this same intervention in a fully powered, 3-arm efficacy/effectiveness trial. The goal of this study is to randomize 180 smokers across three sites to test the efficacy/effectiveness of the intervention at increasing point prevalence abstinence by reducing anxiety and depression at a 1-month follow-up (the end of treatment timepoint/ approximately 1-month post quit day) and a 6-month follow-up (approximately 6-months post quit day).
This study evaluates clinical and radiographic parameters among riks factor groups in patients with periimplantitis. This study will also treat and evaluate the patients response before and after surgical treatment.
The purpose of this study is to examine the effect of changes in cigarette package color on smoking behaviors, harm exposure, and risk perceptions when using low nicotine content (LNC) cigarettes.
The purpose of this research is to measure the extent of lung inflammation between different groups of participants using a radioactive tracer called [18F]NOS. A radioactive tracer is a type of imaging drug that is labeled with a radioactive tag and injected into the body.
Background: Electronic cigarettes (EC) mainly containing nicotine (88-95 % of users) are widely and growingly used worldwide. It is estimated that there were 1.7 million daily users in France in 2016. Although the number of publications about its use is increasing exponentially, there are no evidence based, unbiased, head-to-head comparison data about its efficacy as an aid to smoking cessation. As of today, only two head-to-head randomized studies have been published, both reported negative results at the main endpoint but they used first and second generation EC delivering nicotine with low or unknown bioavailability. Recent EC deliver nicotine with largely improved bioavailability. One of the randomized studies compared EC with and without nicotine to nicotine patch and reported similar smoking cessation rate at main outcome. However, there is no published, double blind study comparing EC use with a well-studied, licensed smoking cessation medication. Superiority of EC with nicotine compared to EC without nicotine and to a reference smoking cessation medication while collecting also straightforward information about safety, would allow proposing EC with nicotine to the large population of smokers who intend to quit and situate it among the approved smoking cessation treatments. The clinical study's hypothesis: EC containing nicotine can be considered as a nicotine replacement therapy having, probably, a better bioavailability of nicotine than the marketed pharmaceutical NRTs, first line medications of smoking cessation. It is therefore of interest to compare EC containing nicotine to EC without nicotine but also to a reference medication with demonstrated efficacy in smoking cessation. We hypothesize that EC with nicotine provides a higher smoking abstinence rate than EC without nicotine and may be as good as varenicline, our reference medication.
Grip&Health: randomised trial which will examine the effect of theory-based multicomponent behavioural intervention for reducing stress, smoking and improving financial health and perceived health of low-SES residents in Rotterdam. Between January 2018 and July 2018, a total of 300 participants will be recruited and randomised either to a stress management program (SM), stress management with a buddy program (SM-B) or a control condition. The investigators hypothesise that compared to participants in the control condition, participants in the intervention arms will demonstrate reduced stress, reduced smoking and improved financial health and perceived health.
The objective of this study is to test the effect of smoking cessation in pregnancy or in lactation on preventing rapid infant adiposity gain. Investigators propose a randomized, controlled experiment among smoking pregnant women from 1st prenatal care visit through 6 months of postpartum period. Two-phase randomization will be applied to separate the effects of smoking cessation in two different critical periods (i.e., pregnancy and lactation) on infant adiposity gain. Investigators will first randomly assign 40 smoking pregnant women into either the multicomponent intervention (N=30) or the education-only control group (N=10). The multicomponent intervention group will receive education and counseling, monitoring and feedback, contingent financial incentives, and family support, while the control group will receive education only. At the end of pregnancy, investigators will further randomize successful quitters (estimated N=20) from the multi-component intervention group into either the continuous multi-component intervention group in lactation (N=10) or the education-only control group (N=10). All women and their newborns will be followed from enrollment to 6 months postpartum. The key outcomes include maternal smoking abstinence confirmed by urine-cotinine and infant gain in weight-for-length z-score. Specific Aim 1 is to examine the effects of maternal smoking cessation intervention in pregnancy on infant gain in weight-for-length z-score from birth to 6 months. Specific Aim 2 is to examine the effect of maternal smoking abstinence intervention in lactation and infant post-weaning gain in weight-for-length z-score among the women who have successfully quit smoking in pregnancy.
The purpose of the study conducted at VA Medical Center in Miami is to determine if smoking electronic cigarettes (known as e-cigarettes) that contain nicotine have less negative effects than regular cigarettes on the person's respiratory health. We will assess this by measuring pulmonary function tests, several body molecules and functionality of the airway cells. We will also evaluate how smokers can maintain exclusive electronic cigarettes use. In this study, some people will continue to smoke regular tobacco cigarettes while others will switch to a nicotine-containing electronic cigarette.
