Tobacco clinical trials at University of California Health

The goal of this clinical trial is to determine whether Emotional Brain Training (EBT), a behavioral modification method, can help manage stress and health problems related to addiction. EBT teaches skills to deactivate harmful circuits (automatic reactions) and activate healing circuits to quickly shift mood from negative to positive. Participants in the EBT group will receive focused, intensive instruction on using these skills to rewire unwanted brain circuits, with the aim of achieving lasting improvements in emotional health and quality of life. The study will assess whether EBT is an effective tool when added to standard of care (SOC), which includes medications for addiction treatment (MAT). Researchers will compare changes in stress, anxiety, and cravings after 8 weeks of EBT plus SOC versus SOC alone. Participants: - will either continue receiving standard treatments (SOC) at the Addiction Recovery Clinic (ARC) at SAC Health in San Bernardino - or receive both EBT and SOC at ARC - in the SOC group will continue monthly visits at ARC and weekly counseling - in the EBT plus SOC group will continue monthly visits and weekly counseling at ARC, along with weekly EBT group sessions by telephone - will complete online assessments at weeks 0, 4, and 8 Upon completion of the study, all participants will resume SOC

Exposure to secondhand tobacco smoke (SHS) is associated with diverse health effects in nonsmokers. 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.
