Perceptions of extended-release naltrexone, methadone, and buprenorphine treatments following release from jail.

Background: Few studies have documented patient attitudes and experiences with extended-release naltrexone (XR-NTX) opioid relapse prevention in criminal justice settings. This study assessed barriers and facilitators of jail-to-community reentry among adults with opioid use disorder (OUD) treated with XR-NTX, buprenorphine, methadone, and no medications.

Methods: This qualitative study conducted individual interviews with a purposeful and convenience sample of adults with OUD who were recently released from NYC jails.

Fluorescent silica particles for monitoring oxygen levels in three-dimensional heterogeneous cellular structures.

Bacterial biofilms are a major obstacle challenging the development of more effective therapies to treat implant infections. Oxygen availability to bacterial cells has been implicated in biofilm formation and planktonic cell detachment; however, there are insufficient tools available to measure oxygen concentrations within complex three-dimensional structures with ∼ 1 µm resolution. Such measurements may complement measures of biofilm structure and cell activity to provide a more comprehensive understanding of biofilm biology.
