Effective Deimplementation of Low-Value Preoperative Testing: Choosing Wisely, From Policy to Practice.
JAMA Surg
January 2025
Department of Surgery and Perioperative Care, Dell Medical School, University of Texas at Austin.
Importance: Routine preoperative blood tests and electrocardiograms before low-risk surgery do not prevent adverse events or change management but waste resources and can cause patient harm. Given this, multispecialty organizations recommend against routine testing before low-risk surgery.
Objective: To determine whether a multicomponent deimplementation strategy (the intervention) would reduce low-value preoperative testing before low-risk general surgery operations.
Interlaboratory comparison of particle filtration efficiency testing equipment.
J Occup Environ Hyg
January 2025
Metrology Research Centre, National Research Council Canada, Ottawa, Ontario, Canada.
Particle filtration efficiency (PFE) is a critical property of face masks, with the most common test methods using sodium chloride as a challenge aerosol. In the absence of bottom-up uncertainty budgets for PFE, interlaboratory comparisons provide an alternative route to robustly quantify the precision and bias of the method. This work presents the results of several interlaboratory comparisons of particle filtration efficiency performed across a network of laboratories.

Department of Postgraduate Program in Animal Science, University of Franca (UNIFRAN), Av. Dr. Armando Salles Oliveira, 201, Parque Universitário, Franca, SP, CEP 14.404-600, Brazil.
Failures in endodontic treatments are common due to microbial resistance in the pulp canal. The study evaluated the in vitro activity of polyhexamethylene guanidine hydrochloride (PHMGH) against endodontic strains, as well as in vivo toxicity. Using minimum inhibitory concentration and minimum bactericidal concentration techniques, PHMGH was effective against all microorganisms, even at low concentrations.

January 2025
Department of Surgery, MacKay Memorial Hospital, 92, Chung-Shan North Road, Section 2, Taipei, 104217, Taiwan.
Noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) can be differentiated from invasive encapsulated follicular variant of papillary thyroid carcinoma (eFV-PTC) by the presence of a tumor capsule or blood vessel invasion in histological examination. The objective of this study was to investigate whether it is possible to distinguish between NIFTP and invasive eFV-PTC before surgery. Patients diagnosed with NIFTP and invasive eFV-PTC from 2017 to 2023 were analyzed for biochemical, ultrasonographic, and cytological features.
