Older Adults and Gentrification: The Positive Role of Social Policy.

Supportive public policies are suggested as ways to lessen gentrification's impact for older adults. While explicit policies designed to help older adults with gentrification are rare, literature on age-friendly cities is a close proxy. We utilized three North American cases undergoing gentrification: New York City, NY, and Denver, CO, in the United States and Hamilton, in Ontario, Canada, to present existing neighbourhood-based policies as social determinants of health in housing, resource access, healthcare, transportation, and communal places.

Heterologous SARS-CoV-2 booster vaccine for individuals with hematological malignancies after a primary SARS-CoV-2 mRNA vaccine series.

Heterologous COVID-19 vaccine boosters have not been evaluated for patients with hematological malignancies. A Novavax booster was administered for 56 individuals with hematological malignancies who had received a primary COVID-19 series and prior boosters with mRNA vaccines only. Blood specimens were obtained at baseline (pre-vaccine), 28 days, and 168 days after vaccination with the Novavax booster.

US Hospital Service Availability and New 340B Program Participation.
