The aim of this project is to evaluate the effectiveness of a program called Contingency Management (CM) in helping Veterans quit smoking during lung cancer screening or cancer care at VA clinics. CM is a behavioral treatment that uses rewards to encourage smoking cessation when verified through biological testing. In the first year, the researchers will develop a mobile CM protocol based on feedback from Veterans and healthcare staff through focus groups. In the second year, they will conduct a pilot study to test the feasibility of the mobile CM program along with counseling and medication for 20 Veterans over a five-week period. The success of the pilot study will determine whether to proceed with a larger randomized controlled trial (RCT) in years three to six, comparing the efficacy of mobile CM with standard treatment. The project will take place at SFVA.</p></div><p itemprop="location" itemscope itemtype="https://schema.org/Place" class="text-right text-muted small"><meta itemprop="name" content="San Francisco VA Medical Center, San Francisco, CA"> <i class="fa fa-map-marker fa-fw" aria-hidden="true"></i> <span itemprop="address" itemscope itemtype="https://schema.org/PostalAddress"> <strong> <span itemprop="addressLocality">San Francisco</span>, <span itemprop="addressRegion">California</span><meta itemprop="postalCode" content="94121-1563"><meta itemprop="addressCountry" content="United States"> </strong> </span></p></div></div></li><li class="trials-list--trial card border trials-list--trial-joinable trials-list--trial-open-to-age-18-and-over trials-list--trial-open-to-sex-female trials-list--trial-open-to-sex-male "><div class="card-body"><h2 class="h4 card-title"> <a href="https://clinicaltrials.ucsf.edu/trial/NCT05829824" class="stretched-link">Tobacco Cessation Care for Cancer Patients by Automated Interactive Outreach</a> </h2><div class="trials-list--trial-details"><p class="h6 "> <i class="fa fa-user d-none d-md-inline" aria-hidden="true"></i> open to eligible people ages 18 years and up </p><div class="trials-list--trial-summary"><p>This is a multi-arm, randomized controlled, pilot study which will recruit cancer patients who have been seen by a UCSF Cancer Center-affiliated clinical department to evaluate the efficacy of "CareConnect".

Smoking is the leading risk factor for postoperative complications and is associated with longer hospital stays, reoperations, and 30-day mortality. Smoking rates among patients undergoing major elective surgery are high, 22.3-43.0%. It is imperative to identify efficacious, strategically timed smoking cessation interventions for surgery patients. CM incentivizes smoking cessation through positive reinforcement (rewards) when bioverified abstinence is achieved. To ensure feasibility, CM must be tailored to the clinical context. CM for smoking cessation has never been delivered before and after major surgery, nor has mobile CM bioverification been trialed perioperatively. The investigators will develop and test a tailored mobile smoking cessation CM protocol for Veterans undergoing major elective surgery.</p></div><p itemprop="location" itemscope itemtype="https://schema.org/Place" class="text-right text-muted small"><meta itemprop="name" content="San Francisco VA Health Care System"> <i class="fa fa-map-marker fa-fw" aria-hidden="true"></i> <span itemprop="address" itemscope itemtype="https://schema.org/PostalAddress"> <strong> <span itemprop="addressLocality">San Francisco</span>, <span itemprop="addressRegion">California</span><meta itemprop="postalCode" content="94121"><meta itemprop="addressCountry" content="United States"> </strong> </span></p></div></div></li><li class="trials-list--trial card border trials-list--trial-not-joinable trials-list--trial-open-to-age-18-and-over trials-list--trial-open-to-sex-female trials-list--trial-open-to-sex-male "><div class="card-body"><h2 class="h4 card-title"> <a href="https://clinicaltrials.ucsf.edu/trial/NCT05021185" class="stretched-link">Interactive Mobile Doctor (iMD) to Promote Tobacco Cessation Among Cancer Patients</a> </h2><div class="trials-list--trial-details"><p class="h6 text-danger"> <i class="fa fa-ban" aria-hidden="true"></i> <span class="sr-only">Sorry, </span> in progress, not accepting new patients </p><div class="trials-list--trial-summary"><p>The proposed pilot study aims to develop and test a patient video educational tool, an interactive Mobile Doctor (iMD), that can be integrated in radiation oncology setting to effectively engage cancer patients receiving treatment at University of California, San Francisco (UCSF) to facilitate smoking cessation and maintaining smoking abstinence in the context of their radiation treatment.

Flight attendants (FA) who worked on commercial aircraft before the ban on tobacco smoking (exposed FAs) had high, long-term levels of occupational exposure to SHS and are a unique population for the study of long-term health effects of chronic exposure to SHS. In previous studies, we have shown that many never-smoking SHS-exposed FAs to have curvilinear flow-volume loops, decreased airflow at mid- and low-lung volumes, and static air trapping (elevated residual volume to total lung capacity ratio [RV/TLC]), abnormalities that are not diagnostic of overt Chronic Obstructive Pulmonary Disease (COPD), but do implicate the presence of an obstructive ventilatory defect, and are consistent with what has been recently described as preserved ratio impaired spirometry (PRISm). The main objective of the study is to determine the effect of a bronchodilator to counter the physiologic abnormalities that are observed in the population of never-smoking SHS-exposed FAs as both proof of concept of the presence of an obstructive lung disease and as a possible therapeutic option to counteract the adverse respiratory effects of chronic exposure to SHS.</p></div><p itemprop="location" itemscope itemtype="https://schema.org/Place" class="text-right text-muted small"><meta itemprop="name" content="UCSF"> <i class="fa fa-map-marker fa-fw" aria-hidden="true"></i> <span itemprop="address" itemscope itemtype="https://schema.org/PostalAddress"> <strong> <span itemprop="addressLocality">San Francisco</span>, <span itemprop="addressRegion">California</span><meta itemprop="postalCode" content="94143"><meta itemprop="addressCountry" content="United States"> </strong> and other locations </span></p></div></div></li><li class="trials-list--trial card border trials-list--trial-not-joinable trials-list--trial-open-to-age-18-and-over trials-list--trial-open-to-sex-female trials-list--trial-open-to-sex-male trials-list--trial-open-to-healthy "><div class="card-body"><h2 class="h4 card-title"> <a href="https://clinicaltrials.ucsf.edu/trial/NCT05999383" class="stretched-link">Clinical Pharmacology of Marijuana-Tobacco Co-administration</a> </h2><div class="trials-list--trial-details"><p class="h6 text-danger"> <i class="fa fa-ban" aria-hidden="true"></i> <span class="sr-only">Sorry, </span> not yet accepting patients </p><div class="trials-list--trial-summary"><p>This is a crossover, randomized, double-blinded clinical pharmacology study enrolling dual cannabis-tobacco smokers to better understand the combined effects of co-administering cannabis and tobacco.
