In early 2023\, patients at SFGH began reporting use of “tranq ” and “iso\,” thought to refer to fentanyl mixed with xylazine and t he synthetic opioid isotonitazene\, respectively. In response\, OTOP launc hed urine toxicology monitoring in March 2023 to provide timely data to pa tients\, clinicians\, and public health leaders. The OCTUPUS study further surveyed a subset of OTOP intake patients about recent substance use and linked their reports with expanded toxicology testing. This talk will revi ew findings from OTOP monitoring and examine OCTUPUS data to clarify the m eaning and clinical significance of reported “iso” use.\n\nJohn Halifa x is an Epidemiology PhD student at UC Berkeley’s School of Public Healt h. He broadly explores the role of neighborhood and place as determinants of health from an ecosocial perspective using flexible\, minimally assumpt ive causal inference methods. His current research includes extending caus al inference methods to account for neighborhood-specific confounding effe cts in multilevel\, high-dimensional data settings\, examining the effect of acute community violence on perinatal outcomes\, and utilizing machine learning to forecast fatal overdoses at the neighborhood level. Prior to p ursuing a PhD\, John worked at the intersection of analytical chemistry\, community health\, and the overdose crisis at San Francisco AIDS Foundatio n and UC San Francisco. John holds an MS in Epidemiology from UC Berkeley and a BS in Chemistry magna cum laude from Haverford College. Outside of w ork\, you will find John riding his bicycle\, cooking heirloom beans\, or watching his favorite soccer team lose again.\n\n------------------------- --------\n\nThe UCSF Drug Use Research Group (DURG) is a city-wide seminar attended by faculty\, postdoctoral fellows\, graduate students\, and othe r Bay Area investigators centering on persons who use drugs. \n\nThe DURG was founded in 2005 after a friendly debate between an epidemiologist and anthropologist on the merits of quantitative versus qualitative research m ethods. These monthly meetings provide a community platform for new and es tablished investigators to present their works-in-progress\, consult on ne w or related research and policy questions\, and prepare for grant applica tions\, conferences\, and publications in a supportive environment. The se minar has been successful in cultivating new research collaborations\, men torship\, and sustaining interdisciplinary and interprofessional dialogue between those engaged in basic sciences\, epidemiology\, clinical research \, and qualitative methods.\n\nOur meetings are not recorded or live-strea med.
