AI Article Synopsis
Article Abstract
Background: Needleless connectors (NCs) were introduced to reduce health care work needlestick injuries (NSIs). If not decontaminated prior to use, NCs can be a portal for patient blood stream infections. The optimal disinfectant, and its application duration, for NC decontamination has not been empirically established.
Methods: Factorial design randomized controlled trial comparing 70% isopropyl alcohol (IPA) and 2% chlorhexidine gluconate (CHG) in 70% IPA for 5, 10, or 15 seconds, in adult medical patients with peripheral intravenous catheters.
Results: At baseline, 153 of 300 NCs (51%) grew microorganisms commonly found on the skin. Decontamination was successful in 150/153 (98%). There was no significant difference in decontamination between 70% IPA or 2% CHG in 70% IPA (P = .62), or decontamination for 5, 10, or 15 seconds (P = .21).
Conclusions: There was no difference in the effectiveness of 70% IPA and 2% CHG in 70% IPA for NC decontamination for peripheral intravenous catheters in the clinical environment. Successful decontamination was not different for applications of 5, 10, and 15 seconds; 15 seconds did not always remove all microorganisms. Factors such as cost, feasibility of compliance, and low risk of allergy support 5 seconds decontamination with 70% IPA as an acceptable approach.

Alcohol-based antisepsis without the use of chlorhexidine for arthroscopy in horses.

Alcohol-based antisepsis has shown experimentally to be as effective as 4% chlorhexidine gluconate (CHG) at reducing bacterial counts (colony forming units; CFU) on equine skin. Our objectives were to determine the immediate and post-surgical reduction in CFU/mL on equine skin prepared with CHG-based or 70% isopropyl alcohol (IPA)-based (without CHG) protocols in a clinical setting with arthroscopic surgery. Our hypotheses were that the logCFU/mL reduction would not significantly differ between protocols immediately after preparation or at the end of surgery.

Z-scheme CeO-TiO@CNT (CTC) heterojunction is fabricated using hydrothermal method and evaluated for removing mixed pollutants (MIX-P) from ciprofloxacin (CPF) and textile contaminations. CTC demonstrated ≈99% removal efficiency against MIX-P under solar irradiation of ≈10 lumens. High removal efficiency of CTC is attributed to reduced bandgap (E), 2.

Background: Anaphylaxis is a systemic allergic reaction that is potentially life-threatening. Occupational anaphylaxis is an anaphylaxis that occurs in an occupational context. In this position paper, we propose diagnostic criteria for occupational anaphylaxis and provide an overview of the current state of knowledge in terms of prevalence, triggers, prevention, and management.

Achieving uniform and high-performing catalyst-coated membranes (CCMs) is a critical challenge in the field of electrochemical energy conversion technologies. This challenge is particularly pronounced in the coating of catalyst inks, where optimizing ink formulations and mixing conditions is essential for producing homogeneous catalyst layers that enhance electrochemical performance. In this study, we investigate the influence of mixing parameters and solvent composition on the rheological behavior and performance of nickel hydroxide-based anode inks, specifically for application in anion exchange membrane (AEM) electrolysis.

Introduction: The purpose of this study was to assess and compare the effectiveness of seven different closed system transfer device (CSTD) product lines following the 2015 NIOSH Vapor Containment Performance Protocol, using a Gasmet™ DX5000 Terra multigas FTIR analyzer.
Methods: Seven different CSTD systems were assessed using a two-task evaluation on their capacity to contain the NIOSH-specified challenge agent, 70% isopropyl alcohol (IPA). Task 1 simulated reconstitution and compounding steps while Task 2 simulated compounding and administration steps.
