Operator-dependent and operator-independent contrast media minimization strategies to prevent acute kidney injury after percutaneous coronary intervention.

Contrast associated acute kidney injury (CA-AKI) is a major complication of contrast media (CM) exposure following percutaneous coronary intervention (PCI), associated with high rates of morbidity and mortality in both early and late phases. During the past years, several CA-AKI prevention strategies based on CM sparing have been proposed, which differ significantly in terms of methodological features and efficacy. In this review, we propose a new classification of these techniques based on their dependency on operators' management.

Search for the Exclusive W Boson Hadronic Decays W^{±}→π^{±}γ, W^{±}→K^{±}γ and W^{±}→ρ^{±}γ with the ATLAS Detector.

A search for the exclusive hadronic decays W^{±}→π^{±}γ, W^{±}→K^{±}γ, and W^{±}→ρ^{±}γ is performed using up to 140  fb^{-1} of proton-proton collisions recorded with the ATLAS detector at a center-of-mass energy of sqrt[s]=13  TeV. If observed, these rare processes would provide a unique test bench for the quantum chromodynamics factorization formalism used to calculate cross sections at colliders. Additionally, at future colliders, these decays could offer a new way to measure the W boson mass through fully reconstructed decay products.
