The James Webb Space Telescope Mission

Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least $4m$. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the $6.5m$ James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

Undertreatment of opioid use disorder in patients hospitalized with injection drug use associated infections

OBJECTIVE: To evaluate the association between medication for opioid use disorder (MOUD) initiation and addiction consultation and outcomes for patients hospitalized with infectious complications of injecting opioids. DESIGN: Retrospective cohort study. SETTING: Four academic medical centers in the United States. PARTICIPANTS: 322 patients hospitalized with infectious complications of injecting opioids in 2018. EXPOSURES: Inpatient receipt of MOUD, initiation of MOUD, and addiction consultation. MEASUREMENTS: The main outcomes of interest were: 1) premature discharge; 2) MOUD on discharge; 3) linkage to outpatient MOUD; 4) one-year readmission; 5) death. RESULTS: 322 patients were predominately male (59%), white (66%), and median age 38, with 36% unstably housed, and 30% uninsured. 145 (45%) patients received MOUD during hospitalization, including only 65 (28%) patients not on baseline MOUD. Discharge was premature for 64 (20%) patients. In the year following discharge, 27 (9%) patients were linked to MOUD, and 159 (50%) patients had at least one readmission. Being on MOUD during hospitalization was significantly associated with higher odds of planned discharge (OR 3.87, P \u3c 0.0001), MOUD on discharge (OR 129.7, P \u3c 0.0001), and linkage to outpatient MOUD (OR 1.25, p \u3c 0.0001), however was not associated with readmission. LIMITATIONS: Retrospective study. Post-discharge data are likely underestimated. CONCLUSIONS: There was dramatic undertreatment with MOUD from inpatient admission to outpatient linkage, and high rates of premature discharge and readmission. Engagement in addiction care during hospitalization is a critical first step in improving the care continuum for individuals with opioid use disorder, however additional interventions may be needed to impact long-term outcomes like readmission
