Special Issue Information

Dear Colleagues,

The annual occurrence of healthcare-associated infections (HCAIs) caused by pathogens, particularly multidrug-resistant bacteria, has a significant impact on millions of patients worldwide. It poses a substantial public health risk and causes a considerable financial burden. Complementing routine hand hygiene practices, the implementation of cleaning and disinfection measures, along with the utilization of antimicrobial coatings, demonstrate promising potential in healthcare environments. Antimicrobial-coating-based approaches, which have garnered substantial commercial investment and academic research endeavors, are widely acknowledged for their potential in mitigating microbial populations on surfaces within clinical settings. This Special Issue will encompass research that harnesses innovative agents or materials and strategies for the development of antimicrobial coatings aimed at preventing infectious diseases. Papers pertaining to the development of novel agents or materials for antimicrobial coatings and the significant prevention of infectious diseases, such as antimicrobial nanomaterials, herbal-medicine-derived antimicrobial agents, antimicrobial peptides, antibiotic adjuvants, and antimicrobial hydrogel dressings, are highly encouraged.

Abstract
Wound infections caused by Staphylococcus aureus often result in localized suppurative lesions that severely impede the healing process, so it is urgent to develop a dress with efficient antimicrobial and pro-healing functions.

Wound infections caused by Staphylococcus aureus often result in localized suppurative lesions that severely impede the healing process, so it is urgent to develop a dress with efficient antimicrobial and pro-healing functions. In this study, the bifunctional injectable hydrogel lactoferrin (Lf)/NZ2114/lithium magnesium silicate hydrogel (LMSH) was first successfully prepared through the electrostatic interaction method. The physical, biological, and efficacy properties are systematically analyzed with good shear-thinning capacity and biocompatibility. More importantly, it inhibits infection and promotes wound healing in a mouse wound infection model after 14 d treatment, and the bactericidal rate and healing rate were over 99.92% and nearly 100%, respectively. Meanwhile, the massive reduction of inflammatory cells, restoration of tissue structure, and angiogenesis in mice showed the anti-inflammatory and pro-healing properties of the hydrogel. The healed wounds showed thickening with more hair follicles and glands, suggesting that the hydrogel Lf/NZ2114/LMSH (Three in One) could be a better dressing candidate for the treatment of S. aureus-induced wound infections.

Introduction: Peri-implantitis poses a significant challenge for implant dentistry due to its association with bacterial colonization on implant surfaces and the complexity of its management. This systematic review aims to assess evidence from in vivo studies regarding the antimicrobial efficacy of titanium (Ti) dental implant surfaces following physical/chemical modifications or the application of various metal element coatings in preventing bacterial growth associated with peri-implantitis. Materials and Methods: A literature review was conducted across four scientific databases (PubMed, Embase, Scopus, Web of Science), encompassing in vivo studies published between 2013 and 2024, and 18 reports were included in the systematic review. Results: The findings suggest that titanium dental implant surfaces, following physical/chemical modifications and metal element coatings, exhibit antimicrobial effects against bacteria associated with peri-implantitis in humans and various animal models. Conclusions: The reviewed studies indicated a reduction in bacterial colonization, diminished biofilm formation, and decreased signs of inflammation in the peri-implant tissues, which provides evidence that physical/chemical alterations on titanium dental implant surfaces or metal element coatings, like silver (Ag), zinc (Zn), magnesium (Mg), and copper (Cu), demonstrate antimicrobial properties in in vivo studies. However, caution is warranted when translating findings to clinical practice due to methodological disparities and high bias risks. Further larger-scale clinical trials are imperative to assess their long-term efficacy and validate their clinical applicability. Full article
