Long-term trends in the incidence of hospital-acquired carbapenem-resistant and antimicrobial utilization in a network of community hospitals in the Southeastern United States from 2013 to 2023.

Background: Carbapenem-resistant (CRE) are an urgent threat to healthcare, but the epidemiology of these antimicrobial-resistant organisms may be evolving in some settings since the COVID-19 pandemic. An updated analysis of hospital-acquired CRE (HA-CRE) incidence in community hospitals is needed.

Methods: We retrospectively analyzed data on HA-CRE cases and antimicrobial utilization (AU) from two community hospital networks, the Duke Infection Control Outreach Network (DICON) and the Duke Antimicrobial Stewardship Outreach Network (DASON) from January 2013 to June 2023.

Space-based observations of tropospheric ethane map emissions from fossil fuel extraction.

Ethane is the most abundant non-methane hydrocarbon in the troposphere, where it impacts ozone and reactive nitrogen and is a key tracer used for partitioning emitted methane between anthropogenic and natural sources. However, quantification has been challenged by sparse observations. Here, we present a satellite-based measurement of tropospheric ethane and demonstrate its utility for fossil-fuel source quantification.

Rapid and sensitive determination of residual prion infectivity from prion-decontaminated surfaces.

Prion diseases are untreatable fatal transmissible neurodegenerative diseases that affect a wide range of mammals, including humans, and are caused by PrP, the infectious self-templating conformation of the host-encoded protein, PrP. Prion diseases can be transmitted via surfaces (e.g.

In Vitro and In Silico Anthelmintic Activity of Extracts of and on .

The aim of this study was to assess the anthelmintic activity of and , on a nematode model, to promote their use in the Cameroonian pharmacopoeia for the treatment of helminthiases. One nematode was used, . First, the effect of the extracts on the eggs and larval stages (L1, L2, and L3) of was evaluated, 100 L of extract and 100 L of parasite suspension (containing 50 eggs) were mixed in a 96-well microplate.

Interannual changes in atmospheric oxidation over forests determined from space.

The hydroxyl radical (OH) is the central oxidant in Earth's troposphere, but its temporal variability is poorly understood. We combine 2012-2020 satellite-based isoprene and formaldehyde measurements to identify coherent OH changes over temperate and tropical forests with attribution to emission trends, biotic stressors, and climate. We identify a multiyear OH decrease over the Southeast United States and show that with increasingly hot/dry summers the regional chemistry could become even less oxidizing depending on competing temperature/drought impacts on isoprene.
