Social determinants of health and mild cognitive impairment in a diverse community sample.

Background: The associations between community-wide social determinants of health and mild cognitive impairment (MCI) among individuals warrant investigation.

Methods: Among 2830 dementia-free individuals aged 65+ years in a community-based US study, we examined cross-sectional associations of MCI (Clinical Dementia Rating = 0.5) with the following potential social determinants of health: at the census tract or block group level obtained from public sources: neighborhood disadvantage (Area Deprivation Index, ADI), air pollution with fine particulate matter (PM), greenspace, Walkability Index, ambulatory healthcare availability per square mile, homicide rate; and at the individual participant level, birth/schooling in a southern US state.

Ethnoracial Identity and Cognitive Impairment: A Community Study.

Background: Identifying potentially modifiable risk factors associated with MCI in different ethnoracial groups could reduce MCI burden and health inequity in the population.

Methods: Among 2845 adults aged 65+ years, we investigated potential risk exposures including education, physical and mental health, lifestyle, and sensory function, and their cross-sectional associations with MCI. We compared proportions of exposures between Black and White participants and explored relationships among race, MCI, and exposures.

Complete genome sequence of bacteriophage MrAaronian isolated from an culture.

Arthrobacteriophage MrAaronian contains a 54,509 bp DNA genome with 87 predicted protein-coding genes. MrAaronian has siphovirus morphology and was collected from a flowerbed soil sample in Poughkeepsie, NY, and isolated on an B-2979 culture. MrAaronian has > 99% nucleotide identity with cluster AW arthrobacteriophages Michelle, Stayer, Sloopyjoe, and StarLord.

Predictors of Driving Cessation in Older Adults: A 12-year Population-based Study.

Background: Changes in physical health and cognition during aging can result in some older adults to stop driving. In this population-based longitudinal study, we describe potential predictors of driving cessation in older adults.

Methods: Age-stratified random population cohort of 1982 adults aged 65 years and older drawn from voter registration lists.

Effect of an Antiracism Intervention on Racial Disparities in Time to Lung Cancer Surgery.

Purpose: Timely lung cancer surgery is a metric of high-quality cancer care and improves survival for early-stage non-small-cell lung cancer. Historically, Black patients experience longer delays to surgery than White patients and have lower survival rates. Antiracism interventions have shown benefits in reducing racial disparities in lung cancer treatment.
