Unlabelled: Though multiplex respiratory pathogen panels (RPP) have high sensitivity, multiple tests are occasionally performed simultaneously or in rapid succession in an attempt to increase the yield. The purpose of this study was to assess the impact of this practice.
Methods: "Multiple testing" was defined as >1 RPP performed within 12 hours on the same patient and specimen type. All cases of multiple testing for adults at two hospitals over a 5-year period were included. Chart review was performed to determine whether discordant results led to a clinical diagnosis or change in clinical management.
Results: Of 18,779 RPPs, 462 (2.5%) represented cases of multiple testing. Twenty-six of 462 cases (5.6%) produced discordant results. Five discordant results (1.1% of 462 multiple testing episodes) were associated with a clinical diagnosis, and 4 (0.9%) influenced clinical management.
Conclusion: Multiple RPP testing facilitates clinical management in <1% of cases. Medical centers may consider de-implementing this practice.

Introduction: The transition to electric vehicles (EVs) has highlighted the need for efficient diagnostic methods to assess the state of health (SoH) of lithium-ion batteries (LIBs) at the end of their life cycle. Electrochemical Impedance Spectroscopy (EIS) offers a non-invasive technique for determining battery degradation. However, automating this process in industrial settings remains a challenge.

Background & Objectives: Hypoferritinemia without anemia (HWA) is an under-recognized public health concern. Early identification and targeted treatment of HWA can prevent unnecessary medication use and potential drug abuse. This study aims to establish clearer guidelines for recognizing and managing HWA, improving patient's outcome.

Shenzhen Bao'an Chinese Medicine Hospital, Guangzhou University of Chinese Medicine, Shenzhen, China.
Objectives: Despite substantial evidence that visceral obesity is an epidemiological risk factor for hyperuricemia (HUA), studies on the connection between the Metabolic Score for Visceral Fat (METS-VF) and HUA remain insufficient. This research focused on METS-VF's potential role as a risk factor for HUA.
Methods: Notably, 8,659 participants from the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2018 were enrolled in this study.
