Filter by:Radical cystectomy provides the best cancer-specific survival for muscle-invasive urothelial cancer. However the postoperative morbidity remains at 11-68 %. Smoking and alcohol consumption above two drinks per day is associated with an increased risk of postoperative morbidity. Six-eight weeks of smoking and alcohol abstinence prior to elective surgery is recommended to reduce this risk, but for cancer patients the preoperative period is often very short. This randomised clinical trial (STOP-OP) will reach a conclusion on the effect of a new Gold Standard Programme for both smoking and alcohol cessation Intervention using the Gold Standard Programme (GSP) on the frequency and severity of postoperative complications after bladder cancer surgery.
This study will assess environmental emissions of selected compounds in a test chamber after cigarette smoking or e-cigarette vaping.
We aim to use an integrated network systems approach to analyze certain existing small airway epithelium (SAE) omic data sets at the genetic, epigenetic (methylation), gene expression, microRNA and metabolomic levels, to develop an initial model of network connectivities and key network pressure points relevant to SAE biology in health and disease.
Previous research shows a significant proportion of smokers work in full-time employment. Given that the majority of smokers do not aware of the smoking cessation services available in Hong Kong, implementing smoking cessation policy in the workplaces may assist a considerable number of smokers to stop or reduce smoking. This study aims to: 1. examine the employers' knowledge, attitudes and practices in promoting smoking cessation in workplace. 2. test the effectiveness of a brief and an intensive smoking cessation interventions to help workers stop smoking In Phase I of this study, a large scale cross-sectional survey will be conducted to 3000 corporate companies in Hong Kong. The questionnaire will examine the employers' knowledge, attitudes and practices in promoting smoking cessation in the workplaces. In Phase II, a longitudinal study will be conducted to evaluate the effectiveness of a smoking cessation intervention offered by the Department of Psychology, the University of Hong Kong. Smokers from the participating companies will be interviewed before the intervention at baseline, immediately after the intervention, and at 1-, 4-, 12-, 26- and 52-week post-intervention follow-ups. The follow-up assessments will consist of a biochemical validation for the self-reported quitters who report quitting in the past 7 days via exhaled carbon monoxide and saliva cotinine concentration tests. Participants' smoking behaviour, knowledge on smoking and satisfaction of the smoking cessation services will also be evaluated. It is hypothesized that the smoking cessation intervention helps workers stop smoking. Employers' knowledge and attitudes are positively associated with the practices in promoting smoking cessation in workplace. Process evaluation: Qualitative interviews, including in-depth interviews and/or focus group will be conducted after 6-month follow-up.
Our overall research goal is to determine how these novel psychosocial factors impact cessation. This pilot study will answer how dual use of other tobacco products, direct to consumer marketing, and the new phenomenon of butting-out and relighting influences cessation, and how understanding impulsivity and task persistence could lead to new and improved behavioral interventions for tobacco dependence. Answers to these pilot questions will lead to the publication of several manuscripts and provide important feasibility data to design large, well-powered clinical trials, population-level epidemiological studies, and contribute to furthering the field of tobacco treatment.
The purpose of this study is to examine the effect of as-needed oral Nicotine Replacement Therapy (NRT) - 2 mg nicotine gum - for smoking cessation in non-daily, or intermittent, smokers, and to study the process of relapse in ITS, using Ecological Momentary Assessment (EMA).
Cigarette smoking is the major risk factor for developing chronic obstructive pulmonary disease (COPD). Patients with COPD have difficulty clearing mucus and debris from their airways. Even smokers who have not developed COPD may have difficulty clearing the airways. This is partly because smoking impairs the function of cilia, tiny hairs lining the airways that sweep out mucus to keep the airways clean. The investigators have found that smoking reduces the length of cilia, which may contribute to the worsened cilia function in smoking and COPD. This is true even in smokers who show no signs of lung disease. The investigators believe that smoking affects levels of genes in lung cells, resulting in shorter cilia.
Cancer of the oral cavity is one of the fastest growing cancers among men in Taiwan. Previous research has established a strong link between betel quid chewing, a common practice among Taiwanese men, and oral cancer. However, despite the strong association, no attempt has been made to develop behavioral measures to facilitate betel quid cessation. This application extends upon existing collaboration between MD Anderson and China Medical University Hospital (CMUH) and seeks to characterize betel quid chewers and their withdrawal symptoms, in order to address an urgent cancer epidemiology issue in Taiwan.
The objective of this research is to determine whether smartphone games show promise for helping smokers increase their chances of quitting. The central hypothesis is that smokers who have access to smartphone games during their quit smoking attempt will smoke fewer cigarettes and report less craving than will smokers without such access.
The Canadian Respiratory Research Network (CRRN) has recently been established to study the origins and evolution of airways disease in the population. The CRRN is funded by the Institute of Cardio-respiratory Health (ICRH), an institute of the CIHR. The Physiology platform will support the other CRRN platforms (biology, imaging, population health, knowledge transfer) by providing a comprehensive characterization of the nature and extent of physiological impairment of respiratory function in smokers at risk for airways disease and in those with early or mild airway obstruction. The planned studies of the physiology group (core sites located at Queen's University, University of British Columbia and McGill University) will initially focus on smoking-related lung injury in those at risk for COPD and in those meeting spirometric criteria for mild airway obstruction, with or without respiratory symptoms. The primary aim of this initial study is to identify and validate sensitive test(s) of peripheral airway dysfunction that may qualify as physiological biomarkers for use in future CRRN studies.
