Filter by:Lung cancer is the leading cause of mortality in the world, and also in Taiwan.Despite the researches and availability in new therapies, it causes the highest mortality and is one of the most preventable cancers as well. Smoking is the most common cause of lung cancer worldwide. Compared to lung cancer in smokers, lung cancer in never-smokers is associated with East Asian ethnicity, female sex, and adenocarcinoma histology. This unique risk group is likely to have distinct molecular drivers, especially EGFR, ALK, and ROS1 mutations.In National Taiwan Cancer Registry data, more than half (53%) of all newly diagnosed lung cancer patients and 93% of female patients are lifelong never-smokers. This scenario is common in East Asia. It is essential to develop a different strategy for screening lung cancer patients with other high-risk profiles. Several risk factors have been identified in never-smoking lung cancer and one of the most important factor is a lung cancer family history (LCFH) in a first-degree relative. Other high-risk occupational or environmental factors include air-pollution exposed occupations (such as traffic policeman and street cleaners) for at least 10 years, cooking index ≥ 110, defined as 2/7 * days cooking by pan frying, stir frying, or deep frying in one week * years cooking, cooking without using ventilation, passive smoke exposure, and history of pulmonary tuberculosis or chronic obstructive pulmonary disorders. As described above, three high risk groups are interested in this study, the previous heavy smokers (group 1); those who has family history (group 2) and those who have high risk occupation or environment factors (group 3). From the published researches, we assume the detection rate to be 1.1% for group 1 based on NLST results16, 2.6% for group 2 (395 out of 12,011 subjects in TALENT), and we assume the detection Group 3 to be 1% after consulting board-certified senior specialists in this field. This is a prospective, multi-center, single arm study in Taiwan of subjects who are eligible to receive LDCT screening based on recommendation of Health Promotion Administration of Taiwan. The primary objective of TRIO part A is the LDCT screening acceptance rate of high lung cancer risk subjects. The primary objective of TRIO part B is the exact lung cancer detection rates in these three groups. Other secondary objectives are also included.
The investigators will conduct a message-exposure experiment with nationally representative samples of smokers, dual-users (cigarettes and e-cigarettes), and young adult non-smokers (aged 18-29). Experimental messages will address the reduction of nicotine in cigarettes. Participants will also complete a follow-up survey after 2 weeks, measuring their recall of the messages and behaviors since message exposure.
The purpose of this study is to examine whether microaggressions relate to multimodal facets of smoking behavior, subjective withdrawal, and urge/craving. Additionally, the second aim is to examine whether smoking deprivation moderates the relation between microaggressions and multiple facets of smoking behavior, subjective withdrawal, and urge/craving.
The purpose of this study is to examine racial differences in smoking behaviors and stress responses between African American and white male smokers.
Smoking Prevention Program is a pilot exploratory study with a standardized curriculum based on the Tobacco Prevention Toolkit from Stanford University and translated into Polish by the members of Students Scientific Association of Oncology at Wroclaw Medical University. The program will assess the effectiveness of a school-based smoking prevention curricula keeping children as never smokers and test the feasibility of engaging medical students and teachers in implementing and evaluating a validated program on smoking prevention within the Polish School System. The research protocols, methods and data collection instruments of a standardized classroom based valid tobacco prevention program from Stanford University will be used for the study. The smoking prevention program is centred on drug resistance, personal self-management and increasing social skills. The program increases knowledge and uses coaching and practice to provide students with the skills to resist social pressures around cigarette use. The secondary outcome of this study is to determine the change in attitudes by Polish Medical Student regarding Cancer Prevention Research. During Smoking Prevention Program workshops, the 5-Session Curriculum for primary schools will be translated, applied and evaluated for polish students. This community-based pilot will engage medical students, the local school district and the local health authority. The Educational program meets the requirements set by Centers for Disease Control and Prevention (CDC) in Guidelines for School Health Programs to Prevent Tobacco Use and Addiction. Following parental consent, the program will be implemented with all 7th and 8th grade students (children age 12-15 years) from the Elementary School in Tyniec Mały. This project is supported by the Head of Lower Silesian Oncology Center, the Head of Department of Oncology of Wroclaw Medical University, the Health and Social Affairs Department of City of Wroclaw and under the patronage of the Lower Silesia Governor's Office, the Polish Society of Oncology, the Polish Society of Public Health, the Lower Silesian Department of Polish Society of Cardiology and the European Association for Cancer Education (EACE). Smoking Prevention Program is funded by the READS Grant Program from the American Association for Cancer Education (AACE).
Diagnostic performance of low-dose chest CT scan combined with lung-RADS classification (version 1.1) for lung cancer screening among former and current smokers.
Smoking negatively affects the prognosis of periodontal disease by impairing tissue healing. While micronucleus is the most popular parameter for demonstrating DNA damage, inflammatory cell and vascular densities are the most evaluated parameters for determining histopathologic changes in the periodontium. This cross-sectional study aimed to evaluate the effects of heavy cigarette smoking and generalized periodontitis on local genotoxic damage to exfoliated oral epithelial cells as well as histopathologic damage to the periodontium. The investigators hypothesized that the genotoxic and histopathologic damage would be increased in smokers with generalized periodontitis.
This is an observational study of participants in two general population health surveys (FinSote 2018 and 2020) who are followed up for their COVID-19 vaccinations or end of follow-up. The primary objective is to examine the association between tobacco use and COVID-19 vaccine uptake and between-dose spacing.
The purpose of the study is to evaluate how limiting the nicotine content in regular cigarettes affects choices for regular cigarette and e-cigarette products. Eligible participants will be of legal age to purchase tobacco products and regularly use both e-cigarettes and regular cigarettes.
This study is examining different messages to motivate older smokers to quit smoking. Participants will be current smokers, between the ages of 50-80 years old, who do not have a history of cognitive impairment or dementia. Participants can expect to take part in a one-time 30 minute online survey.
