Past, present, and future of sustainable intensive care: narrative review and a large hospital system experience.

Healthcare systems are large contributors to global emissions, and intensive care units (ICUs) are a complex and resource-intensive component of these systems. Recent global movements in sustainability initiatives, led mostly by Europe and Oceania, have tried to mitigate ICUs' notable environmental impact with varying success. However, there exists a significant gap in the U.S. knowledge and published literature related to sustainability in the ICU. After a narrative review of the literature and related industry standards, we share our experience with a Green ICU initiative at a large hospital system in Texas. Our process has led to a 3-step pathway to inform similar initiatives for sustainable (green) critical care. This pathway involves (1) establishing a baseline by quantifying the status quo carbon footprint of the affected ICU as well as the cumulative footprint of all the ICUs in the healthcare system; (2) forming alliances and partnerships to target each major source of these pollutants and implement specific intervention programs that reduce the ICU-related greenhouse gas emissions and solid waste; and (3) finally to implement a systemwide Green ICU which requires the creation of multiple parallel pathways that marshal the resources at the grass-roots level to engage the ICU staff and institutionalize a mindset that recognizes and respects the impact of ICU functions on our environment. It is expected that such a systems-based multi-stakeholder approach would pave the way for improved sustainability in critical care.

Data on the arc magmatism developed in the Antarctic Peninsula and Patagonia during the Late Triassic-Jurassic: A compilation of new and previous geochronology, geochemistry and isotopic tracing results.

We present the results of U-Pb zircon dating conducted using laser ablation-inductively coupled plasma mass spectrometry (LA-ICP-MS), isotopic tracing analyses of Hf in zircon and Sr-Nd in whole-rock and whole-rock major oxides, and trace element abundances of 12 plutonic and volcanic rocks present on the Antarctic Peninsula. The dataset is presented in combination with the results of previous studies conducted in both Patagonia and the Antarctic Peninsula. These results were filtered for concordant 206Pb-238U zircon ages and topology of the 40Ar/39Ar age spectra. These results may be useful for researchers studying the geological evolution of southern Gondwana, West Antarctica or Patagonia. The interpretation of this dataset is found in the co-submitted paper by Bastias, et al. (2021a) titled 'A revised interpretation of the Chon Aike magmatic province: active margin origin and implications for the opening of the Weddell Sea'.
