Virus-laden aerosols play a substantial role in the spread of numerous infectious diseases, particularly in enclosed indoor settings. Ultraviolet-C (UVC) disinfection is known to be a highly efficient method for disinfecting pathogenic airborne viruses. Recent recommendations suggest using far-UVC radiation (222 nm) emitted by KrCl* (krypton-chloride) excimer lamps to disinfect high-risk public spaces due to lower exposure risks than low-pressure (LP) mercury lamps (254 nm).

Introduction: Traditional access cavity preparation involves removing the roof of the pulp chamber and smoothing the dentin bulges at the root canal orifice, thereby creating straight-line access. However, this may damage more healthy dental tissue and reduce the tooth's fracture resistance. This case series presents a novel minimally invasive endodontic protocol for one maxillary canine and four mandibular premolars, which required root canal therapy due to labial/buccal cervical decay that caused pulpitis or periapical periodontitis.

During use of sodium hypochlorite bleach, gas-phase hypochlorous acid (HOCl) and chlorine (Cl) are released, which can react with organic compounds present in indoor air. Reactivity between HOCl/Cl and limonene, a common constituent of indoor air, has been observed. The purpose of this study was to characterize the chemical species generated from gas-phase reactions between HOCl/Cl and limonene.

Objective: To provide evidence for further reducing the incidence of central line-associated bloodstream infection (CLABSI) according to investigation of the prevention and control of CLABSI in intensive care unit (ICU) in Shandong Province.
Methods: The questionnaire was developed by experts from Shandong Critical Care Medical Quality Control Center, combining domestic and foreign guidelines, consensus and research. A convenient sampling method was used to recruit survey subjects online from October 11 to 31, 2023 in the province to investigate the management status of central venous catheter (CVC) in ICU units of secondary and above hospitals.
