Homeless veterans' experiences with substance use, recovery, and treatment through photo elicitation.

Background: Homeless veterans often have addictions and comorbidities that complicate utilization of longitudinal health care services, such as primary care. An understanding of experiences of veterans enrolled in a Homeless Patient Aligned Care Team (H-PACT) may improve addiction treatment engagement in these settings. The authors aimed to describe H-PACT veterans' experiences with substance use (SU), substance use recovery (SUR), and substance use treatment (SUT).

Cardiac CD47 drives left ventricular heart failure through Ca2+-CaMKII-regulated induction of HDAC3.

Background: Left ventricular heart failure (LVHF) remains progressive and fatal and is a formidable health problem because ever-larger numbers of people are diagnosed with this disease. Therapeutics, while relieving symptoms and extending life in some cases, cannot resolve this process and transplant remains the option of last resort for many. Our team has described a widely expressed cell surface receptor (CD47) that is activated by its high-affinity secreted ligand, thrombospondin 1 (TSP1), in acute injury and chronic disease; however, a role for activated CD47 in LVHF has not previously been proposed.
