Abstract

Traditionally, the operation of hernia is considered as a clean operation due to expected, low incidence of infection, on the spot of surgical work (SSI). The incidence of SSI in hernia surgery is more frequent then it is assumed. The important risk factors for SSI are the following: type of hernia (inguinal, incisional), operative approach (open - laparoscopic), usage of the prosthetic material and drainage. Comparing to inguinal hernia repair, incisional hernia repair, is more frequently followed by the infection. The laparoscopic operations are followed with the lower incidence of SSI then in the case of open operations. The usage of the mesh does not increase the incidence of SSI, although the consequences of the mesh infection may be severe. A type I of the prosthesis is more resistant to the infection then prosthesis II and III. The mesh infection (type I) never involves its body but it is present around sutures and bended edges. The mesh infection Type II involves entire prosthesis while in the case of Type III it is present in its peripheral part. In the case of SSI, a prosthesis Type I is possible to be saved, while prosthesis Type II must be removed completely; and the same is for the Type III (the partial removal is rarely suggested). The defect that remained after excision of non-resorptive prosthesis is a long-term and very complicated surgical problem. In regard to the position of the mesh, SSI is more common if the mesh is placed subcutaneously then in the case of sub-aponeurotic premuscular, pre-aponeurotic retromuscular or pre-peritoneal mesh placemen. If the infection is present the nontension techniques using non-resorptive prosthetic implants are not recommended. The presence of drainage and its duration increases the incidence of SSI. It is more common for incisional hernioplasty then for inguinal hernia repair. If there is an indication for drainage it should be as short as possible. The cause of SSI for elective operations are bacteria's that arrives from the skin, while in the case of opening of various organs dominant bacteria's originate from them. The superficial infection does not lead to the recurrence, while it is very possible in the case for deep infection. There are no prospective studies that justify the usage of antibiotic prophylaxes in hernia surgery. The antibiotic prophylaxis is indicated for the clean operations when placing the implants and when severe complication is expected. The appearance of SSI increases the price of treatment and may lead to the recurrence.

Total Synthesis and Structural Revision of Rhabdobranin Reveals a Cryptic Gram-Negative Antibiotic.

Gram-negative bacteria present a major clinical challenge but also remain an underexplored source of antibacterial natural products. Resistance-guided genome mining of the entomopathogenic symbiont Xenorhabdus identified the rdb biosynthetic gene cluster, which encodes a putative prodrug antibiotic, pre-rhabdobranin. However, the inability to isolate the proposed active metabolite, rhabdobranin, has prevented direct functional evaluation. Here we report a convergent total synthesis of the proposed structure of pre-rhabdobranin B, which revealed a stereochemical misassignment at the N-terminal arginine residue. Synthesis of both rhabdobranin epimers showed that, although they are nearly indistinguishable by standard analytical methods, inversion at this single stereocenter has a pronounced effect on antibacterial activity. Biological evaluation of the revised rhabdobranin structure revealed potent antibacterial activity against Gram-negative pathogens, including WHO critical-priority carbapenem-resistant Klebsiella pneumoniae. Cellular and biochemical profiling implicated inhibition of protein biosynthesis as its principal antibacterial mechanism. We further show that the GNAT-family acetyltransferase RdbK N-acetylates rhabdobranin, attenuating its activity and establishing a secondary self-resistance mechanism. These findings validate resistance-gene-guided discovery in Gram-negative symbionts as a strategy for uncovering cryptic antibiotics and identify rhabdobranin as a promising scaffold for Gram-negative antibiotic development.

Environmental antibiotic contamination and AMR: Integrating pathways, impacts, and artificial intelligence-driven mitigation.

The widespread contamination of the environment with antibiotic residues is a significant factor contributing to the global crisis of antimicrobial resistance (AMR). Antibiotics from various sources, such as effluents from municipal and hospital wastewater treatment plants, agricultural runoffs, discharges from pharmaceutical manufacturing and improper disposal of expired or unused medicines, create selective pressures in the spread of antibiotic resistance genes. These environmental reservoirs act as hotspots for horizontal gene transfer, facilitating the emergence of multidrug-resistant pathogens. Conventional detection methods including culture-based assays, chromatographic quantification, and molecular diagnostics, provide essential insights but are limited by low throughput, reduced sensitivity to new Antibiotic Resistance Genes, and challenges in real-time monitoring across complex environments. Recent advances, such as whole-genome sequencing, metagenomics, and biosensor-based detection, help to address these gaps by enabling more comprehensive surveillance of the resistome. Artificial intelligence further enhances these approaches by improving data interpretation and pattern recognition, thus complementing traditional and molecular methods rather than replacing them. This review examines the pathways of environmental antibiotic contamination, ecological and health impacts of AMR, and limitations of conventional detection methods. It aims to clarify how these pathways contribute to the AMR crisis, assess the effectiveness of existing surveillance techniques, and identify gaps in current research.

Discovery of Glycosylated β-Amino Acid-Containing Macrolactams from Nonomuraea sp. 0L2P via Genome Mining.

β-Amino acid-containing macrolactams (β-AACMs) are a class of bioactive natural products characterized by nitrogen-containing starter units within polyketide-derived macrocycles. Here, we report four previously undescribed macrolactams, gruelactams A-D (1-4), from Nonomuraea sp. 0L2P, discovered through an integrated approach combining genome mining, 15N-labeling, and antibacterial screening. Their planar structures were elucidated by comprehensive spectroscopic analyses, including 1D and 2D NMR and HRESI-MS, and their configurations were partially assigned based on ROESY data and bioinformatic analysis. Genome sequencing and antiSMASH analysis identified a putative type I polyketide synthase (PKS) biosynthetic gene cluster, enabling the proposal of a biosynthetic pathway. Bioactivity assays showed that gruelactam D (4) exhibits antibacterial activity against Bacillus cereus and Staphylococcus aureus, with MIC values of 8 and 16 μg/mL, respectively. These findings expand the chemical diversity of β-AACMs and demonstrate the utility of genome-guided approaches for discovering bioactive natural products from rare actinomycetes.
