South Africa Smoking Cessation and Engagement in HIV/TB Care Care

The purpose of this study is to integrate elements from existing interventions developed by our team into a single intervention (QUIT-AD), designed to improve smoking cessation and favorable HIV/TB treatment outcomes among individuals with HIV and/or TB in Cape Town, South Africa. If feasibility, acceptability, and preliminary efficacy are demonstrated, the intervention will be ready for large-scale effectiveness/implementation testing. This program will has the potential to dramatically improve public health by increasing the smoking quit rate and facilitating favorable HIV/TB treatment outcomes among patients with HIV and/or TB in resource limited South African settings.

Telegram Messenger Support for Smoking Cessation After Heart Attack

This randomized controlled trial will evaluate whether a 6-month behavioral intervention delivered via Telegram messenger increases smoking cessation rates in patients after myocardial infarction (MI). Adult smokers hospitalized with acute MI who regularly use Telegram will be randomly assigned to either: * INTERVENTION GROUP: Standard care plus a 6-month Telegram chatbot program providing personalized motivational messages, cognitive-behavioral techniques for craving management, and relapse prevention support. * CONTROL GROUP: Standard care (routine physician advice to quit smoking) plus basic surveys via Telegram without therapeutic content. The primary outcome is 30-day point prevalence abstinence at 6 months, verified by blinded telephone interview with participant and corroborating report from a close relative. Secondary outcomes include changes in cigarette consumption, nicotine dependence, motivation, and intervention engagement metrics. This study addresses the critical gap in smoking cessation support after hospital discharge and could provide evidence for a scalable digital health solution in cardiac secondary prevention.

PASCAL Feasibility Study

The goal of this randomized study is to assess if a conversational agent (or chatbot) that the investigators have developed to help with quitting smoking is acceptable to people trying to quit smoking and to also collect initial information regarding its effectiveness. In this study, some participants trying to quit smoking will be provided with this chatbot while other participants will not be

Engaging Pharmacists to Advance Tobacco Treatment Service Delivery

This research will test the effects of a novel program (ENHANCE-TTS) with tools, training, and clinic facilitation support that capitalizes on pharmacists' roles by expanding their scope of practice to deliver tobacco treatment. This effectiveness-implementation study will evaluate the effects of the ENHANCE-TTS program on implementation outcomes and patient-level smoking cessation outcomes in people living with HIV and concurrently identify key barriers and facilitators to implementing this program in practice.

Optimizing Medications and Lung Health in People With HIV Through Pharmacist-led Proactive E-Consults

People with HIV (PWH) continue to experience elevated risk of community-acquired pneumonia despite effective antiretroviral therapy. Pneumonia contributes to hospitalization, respiratory failure, cardiovascular complications, long-term decline in lung function, and mortality. Several modifiable factors increase this risk, including active smoking, inadequate receipt of respiratory vaccinations, and inappropriate or prolonged use of inhaled corticosteroids (ICS) or proton-pump inhibitors (PPIs). OPTIMIZE Lung-HIV is a multicenter, patient-level randomized controlled hybrid Type 1 effectiveness-implementation trial evaluating whether a proactive, pharmacist-led E-consult intervention can improve evidence-based pulmonary pharmacotherapy for PWH. Pharmacists will review electronic health records, generate tailored recommendations, and pre-enter orders related to smoking cessation pharmacotherapy, vaccinations, and deprescribing of ICS or PPIs. Providers may enact or modify recommendations as clinically appropriate. The trial will assess the proportion of recommendations enacted within 3 months (primary outcome) and at 12 months (maintenance) and will use mixed methods guided by CFIR and RE-AIM to evaluate adoption, feasibility, acceptability, and implementation barriers and facilitators.

Enhancing Long-Term Smoking Abstinence Among Cervical Cancer Survivors (Project ACCESS)

The goal of this research study is to compare the efficacy of a treatment approach that comprises both Motivation And Problem-Solving (MAPS)-based telephone counseling and a personally-tailored SMS-delivered text-based approach to quitline-delivered smoking cessation treatment to help participants with a history of cervical cancer or high-grade cervical dysplasia quit smoking.

Ending Tobacco Use Through Interactive Tailored Messaging for Cambodian People Living With HIV/AIDS

The goal of this research study is to test how well an automated text messaging smoking treatment program helps smokers with HIV quit smoking.

Creation of an Infrastructure to Support Delivery of mHealth Interventions for Cancer Patients

Despite the deleterious impact of smoking upon cancer treatment outcomes, smoking prevalence remains alarmingly high among cancer patients. Thus, reducing smoking by cancer patients is a public health priority, but treatments to date have demonstrated limited efficacy. Mobile health (mHealth) interventions have the potential to improve treatment efficacy while also greatly extending reach. The goal of this infrastructure proposal is to build a resource to facilitate the creation of mHealth tools that address the tobacco treatment needs of cancer patients. This resource, which will be available to researchers throughout Florida, would fill a critical gap in mHealth capacity.

Quitxt Mobile Text Messaging Cessation Research Study

The health benefits of smoking cessation by age 30 are much greater than cessation later in life, including gaining 10 years of life, compared with those who continue to smoke. The goal of the proposed study is to evaluate the effectiveness of the bilingual and culturally tailored Quitxt mobile cessation intervention. Quitxt provides interactive messages through texts or chat with visual and video content employing theory- and evidence-based techniques to prompt and sustain cessation. The study will recruit 1,200 Latino young adult smokers aged 18-29 who enroll and agree to make quit attempts, with half randomly assigned (like flipping a coin) to receive Quitxt and half to abbreviated text messages with smoking cessation-related content and referral to the Texas Department of State Health Services cessation program Yes Quit (which has diverse formats, but not explicitly tailored for young Latino adults in South Texas). Participants respond to baseline and follow-up assessments at one, three and six months after their enrollment, and those who report cessation will be asked to provide saliva samples to confirm they quit smoking. The sample size will be sufficient to detect expected higher cessation rates in those who are enrolled in Quitxt than those who are enrolled in Texas DSHS Yes Quit. The investigators will publish results in scientific journals, report them at scientific and community meetings, share them on social media, and publicize them widely. This study has the potential to advance public health by evaluating the effectiveness of a scalable, easily disseminated and adaptable intervention to help young adults, especially Latinos, quit smoking and reduce smoking-related cancer and chronic disease morbidity and mortality and their associated healthcare costs.

Quit-Smoking Study for Native Hawaiians

This study aims to help Native Hawaiian adults quit smoking by testing two common methods: nicotine gum and group-based counseling. Participants will be assigned to one of three groups: (1) nicotine gum only, (2) group counseling only, or (3) a combination of both. The study will take place at public housing sites on O'ahu. Researchers will check if these approaches-alone or in combination-can support people in successfully quitting smoking. The goal is to find out which method works best and is most acceptable in this community.

Reducing Tobacco Smoking: a Transcranial Direct Current Stimulation (TDCS) Telehealth Study

The study aims to evaluate the feasibility of using Dorsolateral Prefrontal Cortex (DLPFC) Transcranial Direct Current Stimulation (tDCS) as a tool to decreasing distress and cigarette smoking. 46 participants currently smoking cigarettes, and seeking to decrease cigarette use will be recruited.

Screening and Multiple Intervention on Lung Epidemics

This prospective randomized pilot trial will evaluate a multiple intervention program of prevention in lifelong smokers aiming at reduction of chronic inflammation status through treatment with low-dose acetylsalicylic acid (ASA), smoking cessation with cytisine, targeted modification of diet and physical activity, in addition to early diagnosis with annual ultra low-dose spiral computed tomography (LDCT).

Feasibility and Acceptability Trial to Reduce Tobacco and Cannabis Use During Pregnancy and Postpartum

Using both tobacco and cannabis during pregnancy is more common in minoritized groups and can make quitting smoking in pregnancy and remaining smoke free postpartum difficult. Investigators will test an intervention to address prenatal depressive symptoms to encourage people to quit tobacco and cannabis during pregnancy and stay quit postpartum.

Effect of Nicotine Gingival Fibroblast Intoxication on the Response of Periodontal Treatment

Impact of nicotine gingival intoxication on the clinical outcomes after periodontitis non surgical treatment

Healthy Family Project: Tobacco Use and Smoke Exposure in Asian American Communities

This study evaluates whether the Smokefree Family Living (SFL) intervention improves quit rates (smoking cessation) and exposure to tobacco contamination that stays in items such as, carpets, walls, and furniture, even after the smoke has cleared (third-hand smoke (THS)) among Chinese American smokers and their non-smoking household members. Smoking remains high among Chinese American males with limited ability to speak English. This causes the non-smoking household members to be exposed to THS, which contains many of the same harmful components as smoking and becomes more toxic as it ages. SFL is tailored for Chinese Americans and combines the contents of the Quit Smoking for a Healthy Family (QS) intervention with additional THS education and cleaning strategies. QS focuses on smoking cessation through educational sessions and support. THS education and cleaning strategies provide information on THS and how to clean the home for THS. SFL may help Chinese American smokers and their non-smoking household members learn about the importance of quitting and the dangers of THS, this may improve smoking cessation and reduce THS exposure

A Study Of Vagal Nerve Stimulation In Conjunction With NRT For Smoking Cessation

The purpose of this study is to provide preliminary evidence for the efficacy of 12 weeks of vagal nerve stimulation (VNS) and nicotine replacement therapy (NRT) for increasing smoking abstinence rates.

Forward to Quit: A Person-centered Mobile Technology Intervention for Smoking Cessation Among Transgender Adults

This study evaluates the feasibility, acceptability, and preliminary efficacy of "Forward to Quit" (F2Q), a person-centered mobile health (mHealth) smoking cessation intervention designed specifically for transgender adults. The intervention was developed in collaboration with transgender individuals and gender-affirming healthcare providers. The study includes usability testing and a remote single-arm pilot trial. Primary outcomes include feasibility and acceptability of both the intervention and remote biochemical verification of smoking cessation. Secondary outcomes include self-reported and biochemically verified smoking cessation, as well as changes in psychosocial factors such as social support and gender affirmation. The goal is to inform a future large-scale trial and address tobacco-related health disparities in transgender populations.

A Multiple Health Behavior Change (MHBC) Intervention for Weight Loss and Smoking Cessation for Pre-Bariatric Surgery Patients

The purpose of this research study is to evaluate a multiple health behavior change intervention for weight loss and smoking cessation using medication (Naltrexone + Bupropion) and behavior therapy in adults seeking bariatric surgery. The intervention will be compared to a standard of care control group.

Smoking Cessation and Menstrual Cycle Phase

Tobacco use is a risk factor for at least 20 types of cancer and remains the leading preventable cause of cancer in Canada. Smoking cessation is an important cancer prevention strategy for the close to 2 million Canadian women who currently smoke. However, findings from controlled trials and real-world clinical settings indicate that women have greater difficulty achieving abstinence following a quit attempt than men. There is some evidence that hormonal levels and fluctuations throughout the menstrual cycle (MC) may contribute to the greater difficulty women experience when trying to quit smoking. In this study, the start of a quit attempt using nicotine replacement therapy (NRT) will be targeted to specific phases of MC. It was hypothesized that starting a quit attempt during the first half of MC (follicular phase) will result in increased quit success compared to starting during the second half of MC (luteal phase) or the usual practice of not targeting quit start date to MC phase.

Development of a MHBC Intervention for Weight Loss and Smoking Cessation for Pre-Bariatric Surgery Patients

The purpose of this research study is to develop and pilot a multiple health behavior change intervention for weight loss and smoking cessation using medication (Naltrexone + Bupropion) and behavior therapy in adults seeking bariatric surgery.

Factors Sustaining Tobacco Abstinence in Cancer Patients Treated With Radio-chemotherapy or Radiotherapy

The TABAC STOP ORL POUMON study aims to evaluate the factors influencing long-term smoking cessation in patients with head and neck cancer (HNC) or lung cancer undergoing radiotherapy or chemoradiotherapy. This is a single-center observational study, following patients at 1, 6, and 12 months after treatment completion. The primary objective is to determine the proportion of abstinent patients at 6 months, while secondary objectives analyze factors influencing abstinence, smoking trajectories, and reasons for relapse. A total of 100 patients will be included to ensure robust statistical analysis.

CONNECTing to LungCare

This study evaluates a smoking cessation intervention (CONNECTing to LungCare) for improving shared decision-making conversations about smoking cessation and lung cancer screening between patients and providers. Shared decision making is a patient care model in which providers offer information regarding risks and benefits, patients express their values and preferences, and then healthcare decisions are jointly discussed between the patient and provider. Patient education, aided by decision support tools, can increase patients' knowledge, decrease their decisional conflict, promote decision making, and improve the patients' perception of risk. CONNECTing to LungCare is an interactive education intervention that addresses lung cancer screening and smoking cessation and provides participants with a tailored summary that may make them more likely to have shared decision-making discussions with their providers about smoking cessation and lung cancer screening.

ACT Lung Health Intervention: Phase Two

This study aims to test a counseling and educational program designed to improve lung health through smoking cessation for Chinese and Korean American smokers at high risk for lung cancer.

Rural Smoking Cessation

Understanding ways to help people who live in rural areas quit smoking is a public health priority. quitting smoking among rural people who smoke is a critical public health concern. People in rural areas smoke at higher rates than those in urban areas, experience high rates of smoking caused cancers and deaths. We are recruiting rural people from around the country to better understand how different quit smoking methods can improve a person's chances of successfully quitting smoking.
