Filter by:The goal of this study is to perform a randomized clinical trial to assess the effects of vitamin C versus placebo on wound healing in mandibular fracture patients.
After developing professional quality materials (audio) for an affordable automated self-hypnosis intervention program for facilitating smoking cessation, stress and pain reduction, researchers aim to gain qualitative reviews of this program, and test its initial feasibility and effects on smoking cessation and reduction in pain and stress. In addition, this study seeks to determine whether higher hypnotizability, as measured by the Hypnotic Induction Profile (assessed at baseline), is a moderator of improved outcome in these conditions.
Randomized, double-blind, before-after controlled trial to assess changes in regional brain activation in response to cigarette-related cues from before to after treatment with bupropion (vs placebo).
The present study was designed as a, single-center, prospective cohort study focusing on the relationship between smoking status and the severity of periodontitis
This exploratory study is part of the global clinical assessment program of IQOS. It was designed to provide scientific evidence to further substantiate the reduced risk potential of using a heated tobacco product (the Tobacco Heating System [THS] marketed as IQOS) as compared to smoking cigarettes. The main goals of this exploratory study were to assess whether switching from cigarette smoking to using IQOS would influence 1) maximum oxygen uptake during incremental exercise (VO2max) and exercise capacity, 2) ability to perform exercise training and thereby influence 3) VO2max after 12 weeks of exercise training, 4) physiological parameters and biological health markers, and finally 5) physical activity levels in daily life.
This study is about investigating smoking and attempts to quit smoking in couples. Participation will help determine better treatment efforts for couples who want to quit smoking. All study procedures will be conducted remotely, allowing couples to interact with study personnel through zoom.
The DELPhi system is a software device that is used for the noninvasive evaluation of brain plasticity and connectivity. The DELPhi software uses EEG and TMS devices as accessories. Standard electro-physiological acquisition is performed using TMS to evoke regional neuronal potentials measured as EEG data. TMS-EEG data is analyzed with regards to conventional, well established characteristics of neuronal network plasticity and connectivity.
The purpose of this project is to understand how different e-cigarettes influence their likeability and use among current smokers who try using e-cigarettes. Participants will receive an e-cigarette to sample over a three week period. During this time period they will complete daily electronic diaries and weekly lab visits. The results from this information will help understand how different types of e-cigarettes are likely to influence cigarette and e-cigarette use.
The purpose of this study is to evaluate the reduction of the Abdominal Aortic Aneurysm (AAA) annual growth rate in patients who switch from smoking cigarettes to using IQOS as compared to patients who continue to smoke cigarettes. The study also aims to provide context to the scale of reduction in the growth rate, by comparing the AAA annual growth rates for continuing to smoke and switching to IQOS with the AAA annual growth rate in smokers who had stopped smoking. The study will further evaluate the effects of switching to IQOS on co-morbidities observed in AAA patients that are related to smoking as well as to assess the effects on relevant clinical risk endpoints linked to smoking related diseases.
This project aims to deliver an evidence-based smoking cessation intervention comprising the provision of brief cessation advice to smokers attending emergency departments and active referral to existing smoking cessation services. The objectives are as follows: 1. To promote this evidence-based project to emergency departments in various hospitals under the Hospital Authority 2. To construct a network with non-governmental organisations (NGOs) to provide smoking cessation services 3. To train healthcare professionals to use the AWARD model to deliver brief cessation advice to smokers 4. To deliver brief cessation advice via healthcare professionals and actively refer smokers to existing smoking cessation services.
