A study by the University of Kansas found that Kansas City's zero-fare bus policy attracted 17% of respondents who started using bus service, particularly among younger people and white residents. The policy also increased overall bus use, with new users without vehicle access making more trips per week than those with access.
A cohort study found that GLP-1 receptor agonist use was associated with a reduced risk of developing nonexudative AMD, but not progression to exudative AMD in individuals with nonexudative AMD. This study may inform future randomized trials evaluating the ocular effects of GLP-1RAs in nondiabetic populations.
Black and Asian patients were underrepresented in clinical trials, leading to worse survival outcomes compared to white counterparts, despite similar progression-free survival rates. Equitable enrollment is crucial for access to cutting-edge treatments and long-term equity in cancer care.
A direct-to-patient digital health intervention increased lung cancer screening rates compared to enhanced usual care. The study's findings suggest that such interventions could improve lung cancer screening across diverse populations and healthcare settings.
