https://www.selleckchem.com/products/r428.html Hearing loss exhibited constant acceleration across the adult lifespan at a rate of 0.0052 dB/year (95% CI = 0.0049, 0.0055). This model predicted mean PTA within 2 dB of accuracy for most ages between 20 and 100 years. From age 80 years to approximately 100 years, the average PTA difference between the better and worse ear was 6.75 dB (95% CI = 5.8, 7.1). This asymmetry was relatively constant (i.e., nonsignificant linear regression coefficient of asymmetry over age = 0.07 [95% CI = -0.01, 0.2]). Hearing loss steadily and predictably accelerates across the adult lifespan to at least age 100 years, becoming near universal. These population-level statistics will guide treatment and policy recommendations for hearing health in the older old. 3 Laryngoscope, 131879-884, 2021. 3 Laryngoscope, 131879-884, 2021.Evidence suggests that where people live, learn, work, and play affects a range of health outcomes for children and adults. Differential access to social, economic, and environmental supports puts some community members at greater risk, leading to disparities in health and well-being. The 2014 release of the For the Sake of All report highlighted persistent health disparities for African Americans in St. Louis, Missouri, and their social and economic impacts on the St. Louis region. This study extends this work by developing partnerships with community organizations and neighborhood residents to address health disparities. Community-based participatory research (CBPR) methods were utilized to engage partners in a 10-month research process to address community concerns that impact health. Seven community residents, neighborhood researchers, engaged in workshops to learn about the research process and used techniques to gather information to implement action strategies. Neighborhood researchers selected 14 vacant lots to implement their action plan, which included visions for repurposing the land into a community park, p
