Filter by:Phase III randomized, 2 x 2 design, open label, multi-center study that will assess the removal of filter ventilation on smoking behavior and biomarkers in a tobacco and nicotine product marketplace simulation of a real world environment.
Smoking is a major environmental risk factor associated with common forms of human chronic periodontitis. The aim of the present study was to evaluate apoptotic tissue alterations and tissue destruction in smoker and non-smoker chronic periodontitis patients and healthy individuals. The investigators of the study suggest that smoking decrease tissue quality and increase inflammation level in gingival tissues in both healthy individuals and periodontitis patients. One possible mechanism for this is suggested to be increased apoptosis.
The goal of this study is to determine whether the novel smartphone application designed specifically for cancer patients to quit smoking (Quit2Heal) provides higher quit rates than the current standard smoking cessation app.
The purpose of this study is to test the effects of a medication called metformin (Glucophage®) on smoking behavior. This medication is FDA-approved for treatment of type-2 diabetes. It is being used for research purposes in this study. Participants will be randomized to one of 3 treatment groups: low dose of metformin, high dose of metformin, or placebo.
Prior and recent evidence suggests a role of medial prefrontal cortex (MPFC) in cigarette smoking. Episodic Future Thinking (EFT) has also been shown to be associated with increased delayed discounting and reduced cigarette self administration. In the present study, we will examine whether a single administration of theta-burst transcranial magnetic stimulation (tbTMS) can increase Episodic Future Thinking and delayed discounting while reducing craving for nicotine.
The 2-year research plan will test the Extended Put It Out Project (POP-6) in a pilot randomized trial (N=168) compared to TSP-6, as well as comparing POP-6 and TSP-6 to the POP-3 and TSP-3 interventions from a previously-conducted trial. Participants will be young adults who smoke, identify as sexual or gender minorities (SGM), and use Facebook. Primary outcome will be biochemically verified 7-day abstinence from smoking at 3 and 6 months. Secondary outcomes will be a quit attempt (y/n), stage of change, and thoughts about tobacco abstinence at 3 and 6 months.
Cigarette smoking is a patient-related factor that can affect healing of periodontal tissues and the success rate of root-coverage procedures. Neither the nature nor the mechanisms of action of cigarette smoking on root coverage are fully understood. Therefore, the hypothesis that cigarette smoking has negative impacts on the outcomes of root coverage after CAF surgery in systemically healthy individuals with an initial gingival thickness of at least 0.8 mm and who practice optimal oral hygiene was tested. It was also hypothesized that baseline analysis of disease-related biomarkers would shed light on the underlying mechanisms of a possible effect.
A randomized controlled trial for the efficacy of contingency management to encourage smoking cessation and weight loss.
Smoking is the major preventable risk factor in the initiation and progression of periodontal diseases. Periodontitis risk was found to be 3.9 times higher among smokers aged between 19-30 years and 2.8 times higher among smokers aged 31-40 years compared to non-smokers. Aggressive periodontitis (AgP), is characterized by a rapid attachment loss usually incompatible with the amount of plaque and dental calculus. It is often not possible to predict the prognosis of treatment with various treatment options in cases of aggressive periodontitis. It was hypothesized that non-smoker patients with generalized aggressive periodontitis (GAgP) will respond better to conventional mechanical non-surgical periodontal therapy compared to the smokers. Therefore, the aim of this study was to evaluate the effects of smoking on the outcomes of non-surgical periodontal treatment in terms of the clinical, biochemical and microbiological parameters.
Dietary choices are influenced by several factors, including physiological, social or genetic factors. Among these, flavor is the most important determinant modulating the preferences versus specific foods. Flavor perception is the result from the sensory integration of taste and odor properties of food. Aim of the present study was to assess flavor abilities in a large population using a validated perceptive test.
