Importance of Ultraviolet-C (UV-C) Emitter Configuration for the Attenuation of Staphylococcus aureus and Candida auris Pathogens.

Background: The relative importance of different ultraviolet-C (UV-C) emitter configurations on the attenuation of vegetative bacterial and fungal pathogens has not been assessed. We hypothesized that emitter configuration would impact the efficacy of UV-C attenuation of and ( pathogens.

Methods: American Type Culture Collection (ATCC) (ATCC 6538) and (ATCC MYA-5001 carriers (ReadyNowTM Test Carriers, Stratix Labs Corporation, Saint Paul, MN) were mounted on an aluminum stand along with three calibrated radiometers (International Light Technologies model ILT1270, Peabody, MA).

Importance of Ultraviolet-C (UV-C) Emitter Configuration for Clostridioides difficile Attenuation.

Background: The impact of ultraviolet-C (UV-C) emitter configuration on pathogen attenuation has not been assessed. We hypothesized that emitter configuration would impact UV-C efficacy for () attenuation.

Methods:  carriers (ReadyNow Test Carriers, Stratix Labs Corporation, Saint Paul, MN) inoculated with > 10 American Type Culture Collection (ATCC) 43593 (according to American Society for Testing and Materials (ASTM) 3135 standards) were obtained, and the following experiments were conducted from April to August of 2023.

Anesthesia machine checkout and room setup: a randomized, single-blind, comparison of two teaching modalities.

Background: Novel methods for teaching are needed to enhance the efficiency of academic anesthesia departments as well as provide approaches to learning that are aligned with current trends and advances in technology.

Methods: A video was produced that taught the key elements of anesthesia machine checkout and room set up. Novice learners were randomly assigned to receive either the new video format or traditional lecture-based format for this topic during their regularly scheduled lecture series.

Hurdles to helium gas laparoscopy and a readily available alternative.

Background And Purpose: Although multiple series of helium insufflation-assisted laparoscopic surgery are reported, we encountered difficulty at many levels when arranging a laparoscopic nephrectomy with helium insufflation. We present our experience with attempting to use helium gas as an insufflant and our successful use of argon gas as an adjunct to CO(2) insufflation with a case report as illustration.

Materials And Methods: The patient is a 66-year-old man with a progressively enlarging 3.
