Outcomes of Ottawa, Canada's Managed Opioid Program (MOP) where supervised injectable hydromorphone was paired with assisted housing.

Background: The Ottawa Inner City Health's Managed Opioid Program is the first, to our knowledge, to pair injectable opioid agonist hydromorphone treatment with assisted housing for people experiencing homelessness with severe opioid use disorder (OUD) and injection drug use. We aimed to describe this program and evaluate retention, health, and social wellbeing outcomes.

Methods: We retrospectively assessed the first cohort of clients enrolled in the Managed Opioid Program between August 2017-2018.

Single cell RNA sequencing of human liver reveals distinct intrahepatic macrophage populations.

The liver is the largest solid organ in the body and is critical for metabolic and immune functions. However, little is known about the cells that make up the human liver and its immune microenvironment. Here we report a map of the cellular landscape of the human liver using single-cell RNA sequencing.
