Outcomes, mortality risk factors, and functional status post-Norwood: A single-center study.

Background: The Norwood operation (NO) for infants with univentricular physiology has high interstage mortality. This study evaluated outcomes and risk factors for mortality following NO.

Methods: Retrospective single-center study of patients undergoing NO from 2010 to 2020.

Determining the association of hyperoxia while on extracorporeal life support with mortality in neonates following Norwood operation.

Background: Patients requiring extracorporeal life support (ECLS) support post-Norwood operation constitute an extremely high-risk group.

Materials And Methods: We retrospectively aimed to evaluate the relationship of hyperoxia with mortality and other clinical outcomes in patients who required ECLS following Norwood operation between January/2010 and December/2020 in a large volume center.

Results: During the study period 65 patients required ECLS post-Norwood.

Impact of solar geoengineering on temperature-attributable mortality.

Decisions about solar geoengineering (SG) entail risk-risk tradeoffs between the direct risks of SG and SG's ability to reduce climate risks. Quantitative comparisons between these risks are needed to inform public policy. We evaluate idealized SG's effectiveness in reducing deaths from warming using two climate models and an econometric analysis of temperature-attributable mortality.

What Characteristics Modify the Relation of Neighborhood Walkability and Walking Behavior in Older Adults?

Background And Objectives: Neighborhood walkability can influence walking behaviors in older adults. However, its associations of walkability with walking may differ by demographic, socioeconomic, health, social, and residential characteristics due to factors such as increased vulnerability to environmental factors or increased resilience.

Research Design And Methods: In a sample of older adults ( = 493, median age = 82 [range 78-89], 56% female, 31% Black), a walkability index was derived from audits of Google Street View images of participants' immediate neighborhoods.
