Purpose: The capnodynamic method, End Expiratory Lung Volume CO (EELV-CO), utilizes exhaled carbon dioxide analysis to estimate End-Expiratory Lung Volume (EELV) and has been validated in both normal lungs and lung injury models. Its performance under systemic hypoxia and variations in CO elimination is not examined. This study aims to validate EELV-CO against inert gas wash in/wash out (EELV- SF6, sulfur hexafluoride) in a porcine model of stable hemodynamic conditions followed by hypoxic pulmonary vasoconstriction and inhaled nitric oxide (iNO).

The Department of Veterans Affairs (VA) is the largest integrated healthcare system in the US and uses a variety of approaches to manage utilization and cost of MS DMT. The objective of this paper is to compare national utilization trends in the VA to the US Medicare program, another large federal public healthcare program.

- Sepsis remains a leading cause of death worldwide, highlighting the need for better monitoring tools in critical care.
- Capnodynamically derived mixed venous oxygen saturation (Capno-SvO) offers a non-invasive alternative to traditional invasive monitoring methods, potentially improving patient care in septic cases.
- A study evaluated Capno-SvO against established methods in a porcine model, finding high agreement rates and suggesting Capno-SvO could be a reliable tool for tracking changes in critically ill patients.
Article Synopsis
- The SisAl process offers a sustainable way to produce silicon and alumina using side streams from the silicon and aluminum industries, addressing the growing global demand for these materials.
- Pilot-scale trials confirmed the process's stability and controllability, with silicon alloy compositions averaging 70-75% Si, while different reductants showed minimal impact on alloy composition.
- Adjusting the stoichiometry of input materials allows control over product composition, and acidic slag performed better for future scaling, yielding higher silicon and alumina content compared to neutral slags.
Aim: The aim was to investigate mortality among Swedish seafarers compared to the general population, and differences in mortality between occupational categories and differences over time.
Methods: Longitudinal register-based cohort study of 85,169 Swedish seafarers registered in the Swedish Transport Agency's Seafarers' Registry (SR) 1985-2013. The cohort was matched with the Swedish Cause of Death Register.
