Abstract

Objective: To determine if engagement in office-based opioid treatment decreases emergency department, urgent care visits, and hospitalizations for acute opioid-related events (OREs) among adolescents with opioid use disorder.

Study design: This retrospective cohort study identified all emergent and outpatient visits among adolescents, age 10-19 years, referred for office-based opioid treatment between January 1, 2006 and December 31, 2016. Patients were dichotomized into 2 cohorts: those who did and did not engage in office-based opioid treatment. The primary end point was the difference in the proportion of visits over the study period for acute OREs between cohorts and within the office-based opioid treatment cohort before and after referral. Secondary end points assessed change in the proportion of outpatient visits for treatment unrelated to opioid use disorder.

Results: Four hundred five emergent and outpatient visits were identified: 285 (70.4%) in the office-based opioid treatment cohort and 120 (29.6%) in the non-office-based opioid treatment cohort. After office-based opioid treatment engagement, 27.8% of visits in the office-based opioid treatment cohort were for acute OREs vs 80.8% in the non-office-based opioid treatment cohort (OR, 0.092; 95% CI, 0.052-0.160; P < .001). Outpatient visits in the office-based opioid treatment cohort were 10.9 times that of non-office-based opioid treatment (OR, 10.9; 95% CI, 6.23-19.16; P < .001). Within the office-based opioid treatment cohort, emergent visits decreased from 76.1% to 27.8% (OR, 0.121; 95% CI, 0.070-0.210; P < .001) and the odds of outpatient services was 8.3 times more after engagement (OR, 8.27; 95% CI, 4.78-14.4, P < .001). Conclusions: The absolute decrease in emergent visits for acute OREs was 53% in adolescents engaged in office-based opioid treatment, representing a relative decrease of 65.6% compared with adolescents not engaged. An analysis of visits before and after office-based opioid treatment demonstrated similar decreases, suggesting that office-based opioid treatment has a significant impact in decreasing acute OREs in the adolescent population.

Abstract

Tropane alkaloids (TAs) are a class of phytochemicals produced by plants of the nightshade family used for treating diverse neurological disorders. Here, we demonstrate de novo production of tropine, a key intermediate in the biosynthetic pathway of medicinal TAs such as scopolamine, from simple carbon and nitrogen sources in yeast (Saccharomyces cerevisiae). Our engineered strain incorporates 15 additional genes, including 11 derived from diverse plants and bacteria, and 7 disruptions to yeast regulatory or biosynthetic proteins to produce tropine at titers of 6 mg/L. We also demonstrate the utility of our engineered yeast platform for the discovery of TA derivatives by combining biosynthetic modules from distant plant lineages to achieve de novo production of cinnamoyltropine, a non-canonical TA. Our engineered strain constitutes a starting point for future optimization efforts towards realizing industrial fermentation of medicinal TAs and a platform for the synthesis of TA derivatives with enhanced bioactivities.

Abstract

Tropine and pseudotropine with opposite stereospecific configurations as platform compounds are central building blocks in both biosynthesis and chemical synthesis of pharmacologically important tropane and nortropane alkaloids. The supply of plant-derived tropine and pseudotropine still heavily depends on either plant extraction or chemical synthesis. Advances in synthetic biology prompt the microbial synthesis of various valuable chemicals. With the biosynthetic pathway elucidation of tropine and pseudotropine in several Solanaceae plants, the key genes were sequentially identified. Here, the enzymes responsible for converting N-methylpyrrolinium into tropine and pseudotropine from Anisodus acutangulus were characterized. Reconstruction of the six-step biosynthetic pathways into Saccharomyces cerevisiae provides cell chassis producing tropine and pseudotropine with 0.13 and 0.08 mg/L titers from simple feedstocks in a shake flask, respectively. The strains described not only offer alternative sources of these central intermediates and their derived alkaloids but also provide platforms for pathway enzyme discovery.
