Low birthweight rate differences associated with distinct perinatal staffing mixes at federally funded health centers.

Health centers (sometimes referred to as "federally qualified health centers") can play an important role in addressing perinatal inequities. However, there is limited information on how different staffing models in health centers contribute to perinatal outcomes, including the availability of certified nurse midwives (CNMs). Using 2011-2021 Uniform Data System files, we examined 4 staffing models in 1385 health centers: those with no CNMs or obstetricians-gynecologists (OBs) ("non-CNM/OB"), CNM-only, OB-only, and both CNMs and OBs ("CNM/OB").

Losses and emissions in polypropylene recycling from household packaging waste.

In this study we replicated a typical high-quality post-consumer polypropylene (PP) recycling process to investigate its losses and emissions and study potential improvements. To our knowledge this is the first time that quantitative measurements on all process steps have been performed instead of an accumulated yield and emissions in water. In the process an overall PP yield of 85 wt% based on pure PP input is achieved.

Providers' Experiences Discussing Care for Patients with Kidney Failure Who Forgo KRT: A National Qualitative Study.

Background: Many nephrology providers express difficulty in discussing care options for patients who forgo KRT, which hampers their ability to help patients make decisions about their current and future treatment of kidney disease.

Methods: We conducted a qualitative study using interviews with a national sample of nephrology providers (i.e.

The shifting lipidomic landscape of blood monocytes and neutrophils during pneumonia.

The lipidome of immune cells during infection has remained unexplored, although evidence of the importance of lipids in the context of immunity is mounting. In this study, we performed untargeted lipidomic analysis of blood monocytes and neutrophils from patients hospitalized for pneumonia and age- and sex-matched noninfectious control volunteers. We annotated 521 and 706 lipids in monocytes and neutrophils, respectively, which were normalized to an extensive set of internal standards per lipid class.

Plastic recycling stripped naked - from circular product to circular industry with recycling cascade.

This perspective combines various expertise to develop and analyse the concept of technology cascade for recycling waste plastics with the goal of displacing as much fossil crude oil as possible. It thereby presents archetype recycling technologies with their strengths and weaknesses. It then combines them in various cascades to process a representative plastic mix, and determines how much (fossil) naphtha could be displaced and at which energy consumption.
