In environments in which manual decontamination and steam sterilization remains the primary method of sterilization, biofilm formation can increase the risk of disease transmission. To determine the risk of bacterial survival and contamination on surgical instruments, inoculated blood was dried on one instrument and steam sterilized (wrapped or unwrapped) in a set of 4 (including 3 clean). Two of 3 pathogens were recovered at a rate of 15% for unwrapped sets and 33% for wrapped sets.

Polymeric materials are widely used in medical engineering, and with the dynamic development of additive manufacturing (AM) technology, increasing attention is being paid to research on the mechanical strength of composite polymer structures. At the same time, the impact of sterilization on, for example, surgical templates and the influence of the sterilization process on the geometry of these parts have not been sufficiently studied. In this work, the effect of steam sterilization on samples made of polymer materials for medical applications was presented.

Objective: This study aimed to investigate whether noise exposure in hospital sterile supply centers exacerbated the psychological burden on staff, potentially mediated by concerns about physiological health.
Methods: Between July 5 and August 4, 2023, 308 staffs from central sterile supply departments in 30 hospitals in Hainan were chosen by convenient sampling method. They completed self-administered questionnaires to assess noise exposure status and used the Self-Reporting Inventory-90 to quantify the psychological state of staff across three dimensions: somatization, anxiety, and sleep and diet.

The presence of Bacillus cereus in spices and herbs has posed a detrimental effect on food safety. The absence of thorough testing, comprehensive reporting, and vigilant surveillance of the illness has resulted in a significant underestimation of the true prevalence of foodborne illness caused by B. cereus.

Polysaccharide-based hydrogels have attracted significant attention in fields such as drug delivery, tissue engineering, and wound healing, primarily due to their excellent water-retention capacity, biocompatibility, and biodegradability. This study reports the preparation of a hydrogel through the copolymerization of acrylamide (AM) and carboxymethyl cellulose (CMC) using a simple free-radical polymerization method. β-cyclodextrin (β-CD), capable of encapsulating hydrophobic drugs, was chemically modified with double bonds (Ac-β-CD) and incorporated as a pendant unit in the polymerization reaction, forming a ternary copolymer hydrogel with CMC, AM, and Ac-β-CD.
