Diphtheria Toxin-Producing Corynebacterium ramonii in Inner-City Population, Vancouver, British Columbia, Canada, 2019-2023.

We conducted patient chart reviews and whole-genome sequencing of wound specimens containing presumptive Corynebacterium ulcerans from Vancouver, British Columbia, Canada, during July 2019-July 2023. Sequencing confirmed 8/14 isolates were C. ramonii and identified 2 distinct clusters.

Vascular access: Femoral, radial and large-bore alternative access.

Vascular access for coronary, peripheral, and structural interventions has changed significantly over the past two decades. The evolving demand for both large-bore access for valvular interventions and mechanical support devices, and for safer access for coronary interventions, in patients with comorbidities have driven progress in these areas. This review will provide an overview of the techniques of arterial access in the femoral, forearm (radial and ulnar), and alternative (transcarotid, transaxillary, and transcaval) locations based on the latest evidence and experience.

Induced Chirality in QDs Using Thermoresponsive Elastin-like Polypeptides.

Circular dichroism (CD) spectroscopy has emerged as a potent tool for probing chiral small-molecule ligand exchange on natively achiral quantum dots (QDs). In this study, we report a novel approach to identifying QD-biomolecule interactions by inducing chirality in CdS QDs using thermoresponsive elastin-like polypeptides (ELPs) engineered with C-terminal cysteine residues. Our method is based on a versatile two-step ligand exchange process starting from monodisperse oleate-capped QDs in nonpolar media and proceeding through an easily accessed achiral glycine-capped QD intermediate.

Readability of Patient-reported Outcome Measures Used in Plastic Surgery.

Background: Patient-reported outcomes are essential to understanding success in plastic surgery procedures, many that aim to improve quality of life. Patient-reported outcome measures (PROMs) should be written at or below the sixth-grade reading level recommended by the American Medical Association. This study aimed to evaluate the readability of plastic surgery PROMs.

Expanding PFAS Identification with Transformation Product Libraries: Nontargeted Analysis Reveals Biotransformation Products in Mice.

Per- and polyfluoroalkyl substances (PFAS) are widely used persistent synthetic chemicals that have been linked to adverse health effects. While the behavior of PFAS has been evaluated in the environment, our understanding of reaction products in mammalian systems is limited. This study identified biological PFAS transformation products and generated mass spectral libraries to facilitate an automated search and identification.
