Impact of Multi-Component Interventions on High-Risk COPD Smokers

Study Participants: In our study, we focus on smokers who self-report a "current smoking" status or smoking cessation less than 6 months. This trial is a sub-trial of "Impact of Multi-Component Interventions on a High-Risk COPD population" (Protocol ID: CAMS\&PUMC-IEC-2024-040). All smokers in this trial are either from the high-risk COPD population (defined by COPD-SQ score≥16) . Intervention: For study participants in the intervention arm, we will ask them to finish an online COPD-SQ questionnaire with notification of his or her COPD high risk. For those whose score of COPD-SQ ≥ 16, we will provide a face-to-face survey, simple physical examination, pulmonary function tests, and provide a multi-component intervention at baseline. For smokers in the intervention arm, we provide a digital health intervention program, NicQuit, to whom could familiarly use intelligent mobile phones, and health education for all smokers. We also provide community-based spirometry pulmonary function test (PFT) and education to smokers. If smokers whose post-bronchodilator FEV1/FVC\<0.7, they will be spirometry-defined COPD patients and will be encouraged to seek treatment and medication to the superior hospitals. Additionally, we provide (1) another digital health intervention programs to smokers with mental health issues; (2) CBT-based health education for study participants with abnormal BMI; (3) active recruitment into National Essential Public Health Program in China for those with abnormal blood pressure and blood glucose. Intensive follow-ups will be conducted at month 3 (telephone interview), month 6 (face-to-face with full steps of physical examination), and month 12. Comparison: Those who are assigned in the control arm, we will ask them to finish the same COPD-SQ online questionnaire with notification of his or her COPD high risk status and a face-to-face survey. No physical examinations, community-based pulmonary function tests will be given. Outcomes: The primary outcomes are self-reported average number of cigarettes consumed per day, smoking dependence index, and CO measurement.

Trauma-Informed Care for Smoking Cessation for Pregnancy

Trauma-informed approaches have been shown to support recovery from other substance use disorders and involve four key elements: (1) Realizing the prevalence of trauma and pathways to recovery, (2) Recognizing symptoms of trauma, (3) Responding by embedding knowledge of trauma into practices and policies and (4) Resisting re-traumatization (the 4Rs). In close partnership with Breathe California and a public safety-net clinic in San Francisco that serves primarily racial and ethnic minoritized (REM) pregnant women, the 4Rs along with the Ask, Advise, Assess, Assist and Arrange (the 5As) evidence-based intervention for tobacco cessation that is delivered by health care professionals and is a US Public Health Services clinical practice guideline for treating tobacco will be used to create and implement a smoking cessation intervention for pregnant women with experiences of trauma.

Leveraging Community Pharmacists to Optimize Smoking Cessation Services for Rural Smokers in Appalachia

The goal of this clinical trial is to evaluate the effectiveness and implementation of a pharmacist-delivered MTM (medication therapy management) approach, called QuitAid, to quitting cigarette smoking in rural Appalachia. The main questions it aims to answer are: * Is QuitAid, alone or combined with other quitting tobacco treatments, effective? * What makes QuitAid easy or hard to carry out? Is it cost effective? Is it easy to maintain? Treatment: All participants will be given at least 4 weeks of the nicotine patch. Some participants will be randomized (like the flip of a coin) to receive additional treatments (listed below). These groups will be compared to each other to see which combination works best to help them quit smoking. * Smokefree TXT - a texting program that helps people quit smoking * Tobacco quitline - 4 phone sessions to help people quit smoking * 8 weeks of NRT (nicotine replacement therapy in the form of nicotine patches or nicotine patches and lozenge) medication instead of 4 weeks * QuitAid - An MTM program given by the patient's pharmacist. This is a quitting smoking coaching program * Nicotine patch AND nicotine lozenge instead of just nicotine patches

Construal Level as a Novel Pathway for Affect Regulation and Cancer Control

The objective of the proposed research is to conduct a longitudinal experiment on the neurocognitive pathways and individual differences in high-level construal for affect regulation and smoking cessation. The population is adult smokers aged 25-55 who have tried and failed to quit and who are experiencing poverty. The primary endpoints are (a) the similarity in neural representation of high-level construal to one of two candidate pathways, (b) the presence of meaningful individual differences in the neural representation of high-level construal, and (c) as a secondary endpoint, the effect size of the high-level construal condition on smoking as measured by cigarettes per day. Each of these endpoints corresponds to a specific null hypothesis. The null hypothesis for the first endpoint is that high-level construal is not significantly different in its neural representation from down-regulation of craving, which would suggest that high-level construal does not operate through distinct mechanisms from traditional treatments. The null hypothesis for the second endpoint is that the between-subjects variability in the neural representation of construal level does not significantly relate to relevant individual differences measures (e.g., traits, task behavior), which would suggest that individual differences are not meaningfully related to outcomes. Finally, the null hypothesis for the secondary endpoint is that the magnitude of the effect of high-level construal on smoking as measured by reductions in average cigarettes per day is not significantly greater than in the other conditions, which would suggest that the efficacy of the high-level construal condition is not significantly greater than a standard text-messaging intervention. The primary endpoints will be assessed at baseline and change from pre-to-post training (8 weeks).

rTMS-concurrent Behavioral Priming for Reducing Smoking Cravings

The objective of this pilot clinical trial is to test the effects of different types of thinking strategies at the time of repetitive Transcranial Magnetic Stimulation (rTMS), applied to the left Dorsolateral Prefrontal Cortex (DLPFC), on smoking craving and brain activity. Participants will be individuals with moderate to high smoking dependence (smoking at least 8 cigarettes a day) who have no intention of quitting in the next 3 months and are eligible to have rTMS and functional magnetic resonance imaging (fMRI). The main objectives of the trial are: 1. To compare the craving-reducing effects of "upregulation" and "downregulation" of craving while looking at pictures related to cigarette smoking during rTMS versus no regulation of craving while looking at neutral pictures unrelated to smoking. 'Upregulation" is thinking about the immediate positive experience of smoking. "Downregulation" is thinking about the long-term negative consequences of smoking. 2. To examine changes in brain activity that accompany craving reductions produced by rTMS paired with upregulation and downregulation of craving while looking at pictures related to cigarette smoking versus no regulation of craving while looking at neutral pictures unrelated to smoking. Following screening for eligibility, participants will be trained on how to do upregulation and downregulation of craving. The participants will then participate in 3 testing sessions. In each session, the participants will receive rTMS at 20Hz in 50 trains (2000 pulses total), followed immediately by fMRI. Sessions will take place 1-2 weeks apart and will differ in the type of thinking strategy participants will use while looking at pictures during the rTMS: * upregulation of craving while viewing smoking-related images * downregulation of craving while viewing smoking-related images * no regulation of craving while viewing neutral smoking-unrelated images The order of sessions will be randomized across participants.

Detour: a Smartphone Game to Help Youth Quit Smoking

The researchers are testing a mobile game (named Detour) to support smoking cessation in adolescents and young adults (16-25 years). The game will be tested in a randomized-controlled trial (RCT) where Detour is tested against a digital self-help brochure ("Jouw eigen plan om te stoppen met roken" \[in English: Your personal plan to quit smoking\]) as the active control group. The researchers will recruit 604 participants (aged 16-25) and randomly assign them to receive the game or brochure intervention. The duration between pre-test and post-test for both groups is 5 weeks during which participants can access (parts of) their respective intervention. All participants quit smoking at the end of week 1 of the intervention period. Data is collected on smoking behaviour, intervention usage, and emotional well-being.

Early Life Intervention in Pediatrics Supported by E-health - SMOKE

Unrestricted parental smoking habits are lifestyle risk behaviors associated with chronic, systemic inflammation, which promotes the pathogenesis of non-communicable diseases (NCDs). Exposure to secondhand tobacco smoke in early life contributes to the development of specific NCDs in children, i.e. asthma. Early preventive measures to improve lifestyle behavior in parents are therefore of utmost importance. The aim of ELIPSE-II is to assess whether an eHealth application intervention for parents is feasible and efficacious in lowering levels of urinary cotinine as a measure of second-hand smoke exposure in their children .

The Next Step in Smoking Prevention: the Reduction of Tobacco Retail Outlets, a Comprehensive Policy Evaluation

Few countries have legislation to reduce the number and types of tobacco retail outlets. The Netherlands plans to ban tobacco sales in supermarkets in 2024. The overall aim of this proposed research is to evaluate the implementation of new legislation to reduce the number and types of tobacco outlets in the Netherlands, up until and including the ban on sales of tobacco in supermarkets. In a comprehensive policy evaluation, the investigators plan to examine (1) the impact of the policy on the number and types of tobacco outlets, (2) the impact on attitudes and behaviors of smoking adults and non-smoking youth, and (3) the influence of the tobacco industry on the policy process and the retail environment. In addition, the investigators plan to focus on differential effects in disadvantaged neighborhoods, where both smoking rates and tobacco outlet density are typically highest. The investigators bring together a unique combination of economic, psychological, and journalistic research methods. The investigators examine the impact of the new legislation on the amount and type of tobacco outlets and on the number of smokers by using routinely collected monitoring data. The investigators examine the impact of the legislation on smoking susceptibility of non-smoking youth and on impulse tobacco purchases by smoking adults with yearly quantitative surveys (two surveys before the policy implementation and two after) and with qualitative interviews and discussion sessions. The investigators examine whether these impacts differ for disadvantaged versus non-disadvantaged neighborhoods. The investigators examine what strategies the tobacco industry uses to influence the new legislation, policy processes, and the tobacco retail environment by performing a journalistic investigation, using for example documents obtained by Freedom of Information Act requests, (possibly) leaked documents from insider meetings, and interviews with insiders. Our research will provide a comprehensive evaluation of the effects of the implementation of the proposed legislative measures. Based on our results, the investigators will formulate recommendations for the Dutch Cancer Society, the Dutch government, and for other countries who consider reducing the number of tobacco outlets; highlight potential areas for further development and improvement within the legislative framework and provide recommendations on how to counter the lobby from the tobacco industry.
