Spatiotemporally Detailed Quantification of Air Quality Benefits of Emissions Reductions-Part I: Benefit-per-Ton Estimates for Canada and the U.S.

The U.S. EPA's Community Multiscale Air Quality (CMAQ)-adjoint model is used to map monetized health benefits (defined here as benefits of reduced mortality from chronic PM exposure) in the form of benefits per ton (of emissions reduced) for the U.

Spatiotemporally Detailed Quantification of Air Quality Benefits of Emissions-Part II: Sensitivity to Study Parameters and Assumptions.

Adjoint modeling, using U.S. EPA's Community Multiscale Air Quality (CMAQ), has been performed to provide location-specific monetized health benefits from the controls of primary PM and PM precursors (NO , SO, and NH) across North America.

Estimating Model-Based Marginal Societal Health Benefits of Air Pollution Emission Reductions in the United States and Canada.

We developed spatially detailed source-impact estimates of population health burden measures of air pollution for the United States and Canada by quantifying sources-receptor relationships using the benefit-per-ton (BPT) metric. We calculated BPTs as the valuations of premature mortality counts due to fine particulate matter (PM; particulate matter ≤2.5 μm in aerodynamic diameter) exposure resulting from emissions of one ton of a given pollutant.

The influence of the American Association for Thoracic Surgery on clinical trial development by cardiothoracic surgeons.

Objective: Clinical trials play a critical role in the rapidly evolving field of cardiothoracic surgery and the American Association for Thoracic Surgery Clinical Trials Methods Course has provided a biannual symposium led by preeminent surgeons with vast experience in planning, conducting, and analyzing surgical clinical trials. This study hypothesizes that participation in the course is associated with future success in clinical trial leadership.

Methods: A list of course attendees (2014-2022) was queried in ClinicalTrials.
