Impact of the COVID-19 pandemic on breast cancer mortality in the US: estimates from collaborative simulation modeling.
This study’s objective was to project the impact of COVID-19 on future breast cancer mortality between 2020 and 2030. Three established Cancer Intervention and Surveillance Modeling Network breast cancer models were used to model reductions in mammography screening use, delays in symptomatic cancer diagnosis, and reduced use of chemotherapy for women with early-stage disease for the first 6 months of the pandemic with return to prepandemic patterns after that time. The models project by 2030 950 cumulative excess breast cancers deaths related to reduced screening, 1314 deaths associated with delayed diagnosis of symptomatic cases, and 151 deaths associated with reduced chemotherapy use in women with hormone positive, early-stage cancer.

Neighborhood walkability and mortality in a prospective cohort of women.
The purpose of this study was to evaluate neighborhood walkability in relation to the risk of death for women. Participants were recruited in New York City from 1985 to 1991 and tracked for an average of 27 years. Researchers also conducted survival analyses using Cox proportional hazards models to assess association between neighborhood walkability and the risk of death from any cause. Results indicated that residence neighborhoods with higher walkability scores was associated with a lower mortality rate. No association was found between neighborhood walkability and risk of death from cardiometabolic diseases, but exploratory analyses suggested that outdoor walking and average BMI mediated the association between neighborhood walkability and mortality.

Black-white disparities in maternal in-hospital mortality according to teaching and black-serving hospital status.
This study’s objective was to determine whether black-white disparities in maternal in-hospital mortality during delivery vary across hospital types (black-serving vs non-black and teaching vs non-teaching) and whether overall maternal mortality differs across hospital types. The authors performed a population-based, retrospective cohort study of 5,679,044 deliveries among black (14.2%) and white patients (85.8%) in 3 states (California, Missouri, and Pennsylvania) from 1995 to 2009. Examination of black-white disparities found that after risk adjustment, black patients had significantly greater risk of death and that the disparity was similar within each of the hospital types. At teaching hospitals, mortality was similar in black-serving and nonblack-serving hospitals. Among non-teaching hospitals, mortality was significantly higher in black-serving vs nonblack-serving hospitals. Over half (53%) of black patients delivered in nonteaching black-serving hospitals compared with just 19% of white patients.
