        Abstract：Aerogels are 3D porous materials with broad applications in various fields due to their structural characteristics and physicochemical properties. In recent years, aerogels are getting more and more attention as the unprecedented global pressure of the energy and environmental problems grows. As porous materials with high surface area and specific functional groups, aerogels are ideal to be used to preferentially adsorb certain toxic molecules or ions in the air and water. Such selectivity is achieved by material design, such as pore size control in the aerogel synthesis and/or by surface functionalization during and after synthesis. Certain aerogel compositions have been patented in recent years but their applications in the areas of adsorption remain very limited. After a brief introduction of the aerogel development history and general properties, this perspective highlights the recent progress in the development and mechanistic studies of adsorptive aerogels, and potential application of carbon- and silica-based aerogels as adsorbents in environmental remediation and healthcare areas, such as volatile organic compound (VOC) adsorption and hospital settings as air purification and sterilization. We also discussed gaps and recommended future studies as well as challenges in the fields. It is also apparent that more information is needed for a better understanding of the structural implications of the aerogels in specific pollutant adsorption and applications.

        Abstract：ObjectiveTo measure the content changes of different brands of peracetic acid (PAA) disinfectants under different conditions of use, and to provide data for stability test of peracetic acid.MethodsThe contents of nine brands of PAA disinfectants after single-use opening, daily opening for one hour, daily sampling and dilution, and daily on-site endoscopic decontamination were measured. Moreover, the PAA contents in three brands of disinfectants were determined after the use cycle was extended to 28 days.ResultsThe PAA disinfectants were tested after single-use opening, daily opening for one hour, or daily sampling and dilution. The PAA concentrations in two to three of the nine brands of disinfectants were reduced to less than 1.00 g/L. After daily endoscopic decontamination, the reduction rate of PAA was higher than that of other usage patterns. In this experiment, one PAA disinfectant had good stability, with a content of >1.50 g/L until Day 28.ConclusionThe endoscopic decontaminator is suitable for evaluating the stability of PAA after continuous use. Moreover, the stability of different PAA disinfectants varies greatly, and some disinfectants may not be able to maintain a qualified effective concentration of PAA for continuous use.

        Abstract：Operational and service safety is the priority of nosocomial infection control as the concerns for health and the environment continue to increase. The central sterile supply department (CSSD), as the platform department for cleaning, disinfecting, and sterilizing reusable instruments in the hospital, has the characteristics of complex operation procedures and a large number of personnel involved. Therefore, the occurrence of nosocomial infection controls is effectively minimized only if they are strictly enforced in all procedures. This study analyzes the infection control of CSSD in hospitals and aims to provide some suggestions on the important aspects.

        Abstract：ObjectiveThe present study explores the clinical value of prevention and control of nosocomial infections for improving infection control in multidrug-resistant organisms (MDROs) in ICU.MethodsA total of 200 patients in the intensive care unit (ICU) of Yueyang People's Hospital between January 2023 and March 2024 were randomly selected as study samples. Patients were divided into two groups according to the implementation time of prevention and control of nosocomial infection, i.e., before prevention and control of nosocomial infection (control group) (n=100 cases) and after prevention and control of nosocomial infection (treatment group) (n=100 cases). Comparisons were made between before and after prevention and control of nosocomial infection for MDRO infection incidence, quality score for prevention and control of nosocomial infection, and sanitization pass rate.ResultsA parallel comparison between groups of MDRO infection incidence shows 1.00% in the treatment group and 8.00% in the control group (P<0.05). Comparing air, object surfaces, and nurses' hands in parallel in groups and between groups, the sanitization pass rates were higher in the control group than those of the treatment group (P<0.05). In a parallel between-group comparison, the quality scores of hand hygiene, occupational exposure, disinfection and isolation, medical waste disposal, and sterile technique for prevention and control of nosocomial infection are higher in the control group than the treatment group (P<0.05).ConclusionPrevention and control of nosocomial infections effectively improve the effect of MDRO infection control in the ICU.

        Abstract：ObjectiveTo design a portable luminal light-guiding device and explore its effects in cleaning quality assessment of luminal instruments.MethodsThe luminal instruments collected from Xiangtan Central Hospital from October to December 2023 were tested as experimental subjects. The luminal instruments tested in October were 168 sets, which were tested by white gauze test and set up as Group A, those tested in November were 182 sets tested by white stripe test and set up as Group B, and those tested in December were 175 sets tested by homemade portable luminal light-guiding device and set up as Group C. The effects of three approaches in cleaning quality assessment of luminal instruments were compared.ResultsThe detection rate of unqualified cleaning of luminal instruments in Group A, Group B, and Group C were 0, and the detection rate of unqualified cleaning of the inner lumen was 9.5%, 21.4%, and 34.3%, respectively. The differences in the detection rate of unqualified cleaning of the inner lumen in the three groups were statistically significant (P<0.05). The detection rate of unqualified cleaning of the inner lumen was higher in Group B than in Group A, and the difference was statistically significant (P<0.05). The detection rate of unqualified cleaning of the inner lumen was higher in Group C than in Group A and Group B, and the differences were statistically significant (all P<0.05).ConclusionThe homemade portable luminal light-guiding device is more effective than the white gauze test and the white stripe test in detecting the cleaning quality of the inner wall of luminal instruments, with wide applicability and simplified operation. It is worthwhile to popularize the application in the central sterile supply department.
