Continued Homelessness and Depressive Symptoms in Older Adults.

Importance: Depression is common in adults experiencing homelessness. It is unclear whether continued homelessness is associated with more depressive symptoms.

Objective: To examine the association between residential status and depressive symptoms in adults aged 50 years or older experiencing homelessness at study entry.

Assessing Health Span in Caenorhabditis elegans: Lessons From Short-Lived Mutants.

Genetic changes resulting in increased life span are often positively associated with enhanced stress resistance and somatic maintenance. A recent study found that certain long-lived Caenorhabditis elegans mutants spent a decreased proportion of total life in a healthy state compared with controls, raising concerns about how the relationship between health and longevity is assessed. We evaluated seven markers of health and two health-span models for their suitability in assessing age-associated health in invertebrates using C elegans strains not expected to outperform wild-type animals.

Nurses in Supportive Housing are Associated With Decreased Health Care Utilization and Improved HIV Biomarkers in Formerly Homeless Adults.

A San Francisco study conducted in 2008 showed that the permanent supportive housing program, Direct Access to Housing, dramatically decreased the risk of death in people living with HIV. In our study, we compared the health care utilization patterns and HIV-related biological markers of formerly homeless adults with HIV before and during two types of permanent supportive housing: (a) housing with on-site nursing care for residents, and (b) housing without on-site nursing care. Using nearest-neighbor matching with propensity scoring, the difference in outcomes was calculated.
