RPCI scientists assess safety and efficacy of immunotherapy approach to treat advanced melanoma

A new clinical research study at Roswell Park Cancer Institute (RPCI) will assess the safety and efficacy of a novel immunotherapy approach to treating advanced melanoma. Developed at RPCI by Roswell Park researchers, the investigational vaccine shows promise for treating tumors in patients with stage III/stage IV melanoma, and perhaps as a future therapy for other solid-tumor cancers as well.

Pleasant environment can promote mobility among older community-dwelling individuals

A pleasant environment with parks, green areas and walking routes can promote mobility among older community-dwelling individuals. "Older people who have outdoor recreational facilities, such as walking routes located near their homes, are more physically active and thus more likely to maintain good walking ability," says PhD student Johanna Eronen from the Gerontology Research Center at the University of Jyväskylä, Finland.

Viewpoints: The entitlement crisis is not over; VA needs to deal more effectively with mental health issues; Iowa gives governor new abortion duty

Americans are used to hearing that health care will bust the budget. The Congressional Budget Office projected last year that Medicare, Medicaid and other government health programs would eat up 9.6 percent to 10.4 percent of the nation's gross domestic product by 2037, crowding out many other vital programs. But a new report from the Organization for Economic Cooperation and Development suggests that the United States is not the only country that will struggle to contain public spending on medical care (Eduardo Porter, 6/27).
