Case report: Trauma-induced invasive syndrome presenting with liver abscess, lung abscess, endophthalmitis, and purulent meningitis.
Front Med (Lausanne)
January 2025
Department of Neurology, Guangxi University of Science and Technology First Affiliated Hospital, Liuzhou, China.
Purpose: This study aims to explore the underlying causes, diagnostic strategies, and treatment approaches of trauma-induced invasive syndrome (KPIS) through a rare case report. By highlighting the role of trauma as a potential trigger for KPIS, particularly in high-risk populations such as individuals with diabetes, this study seeks to provide valuable insights for improving clinical outcomes and promoting public health awareness.
Background: invasive syndrome is a multi-organ infectious disease commonly associated with complications such as liver abscess, lung abscess, endophthalmitis, and purulent meningitis, with high mortality and disability rates.
Constructing an Injectable Multifunctional Antibacterial Hydrogel Adhesive to Seal Complex Interfaces Post-Dental Implantation to Improve Soft Tissue Integration.

Soft tissue integration (STI) around dental implants determines their long-term success, and the key is to immediately construct a temporary soft tissue-like barrier to prevent bacterial invasion after implantation and then, promote STI. In response to this need, an injectable multi-crosslinked hydrogel (MCH) with abilities of self-healing, anti-swelling, degradability, and dry/wet adhesion to soft tissue/titanium is developed using gallic acid-graft-chitosan, oxidized sodium alginate, gelatin, and Cu with water and borax solution as solvents, whose properties can be controlled by adjusting its composition and ratio. MCH can not only immediately build a sealing barrier to block the bacterial invasion in the oral simulation environment but also deliver outstanding antibacterial efficacy through the synergism of trapping bacteria and releasing bactericidal agents such as chitosan, gallic acid, aldehyde, and Cu.

Host-microbiome-dietary interactions play crucial roles in regulating human health, yet their direct functional assessment remains challenging. We adopted metagenome-informed metaproteomics (MIM), in mice and humans, to non-invasively explore species-level microbiome-host interactions during commensal and pathogen colonization, nutritional modification, and antibiotic-induced perturbation. Simultaneously, fecal MIM accurately characterized the nutritional exposure landscape in multiple clinical and dietary contexts.

Unlabelled: Streptolysin O (SLO) is a virulence determinant of group A (), the agent of streptococcal sore throat and severe invasive infections. SLO is a member of a family of bacterial pore-forming toxins known as cholesterol-dependent cytolysins, which require cell membrane cholesterol for pore formation. While cholesterol is essential for cytolytic activity, accumulating data suggest that cell surface glycans may also participate in the binding of SLO and other cholesterol-dependent cytolysins to host cells.
