      Engineered bacteriophages (phages) are emerging as a promising next generation of antibacterial phage therapeutics, facilitated by advances in synthetic biology, genome engineering, and computational design. Engineered phage therapeutics offer standardised genome designs, expanded functionality, and improved manufacturability, which could potentially help to overcome regulatory barriers. However, genetically engineered phages raise additional biosafety and environmental concerns, making the development of effective biocontainment strategies important for clinical use. Here, we review current approaches for phage genome engineering, alongside the evolving regulatory frameworks for engineered phages. We evaluate emerging biocontainment strategies for therapeutic phages and propose a framework for assessing trade-offs between biocontainment stringency, evolutionary robustness against escape mutants, therapeutic efficacy, and translational feasibility.

       Background: Pseudomonas aeruginosa is a ubiquitous opportunistic bacterial pathogen associated with nosocomial infections and is a leading cause of infection in persons with cystic fibrosis (pwCF). The front-line treatment for multidrug-resistant P. aeruginosa infections is ceftolozane-tazobactam (C/T). While previous research has characterized clinical P. aeruginosa isolates that evolved resistance to C/T, the collateral effect of evolved resistance on susceptibility to bacteriophages has not been explored.
    Methods: We collected paired P. aeruginosa clinical isolates from 10 pwCF and 18 non-pwCF who developed treatment-emergent C/T resistance. We compared genetic relatedness, acute and chronic virulence phenotypes, and antibiotic and phage susceptibilities between each pair of susceptible baseline and treatment-emergent C/T-resistant isolates.
    Results: Treatment-emergent C/T-resistant isolates were genetically closely related to baseline isolates in all patients. Virulence phenotypes did not differ between pre-and post-C/T exposure isolates, but isolates from pwCF demonstrated differences in protease production, twitching motility, and amino acid auxotrophy compared to isolates from non-pwCF. Treatment-emergent C/T resistance was associated with increased resistance to ceftazidime and ceftazidime/avibactam, but no other trends in antibiotic or phage susceptibility were detected.
    Conclusions: Treatment-emergent resistance to C/T does not cause predictable alterations in phage susceptibility across genotypically and phenotypically diverse multidrug-resistant P. aeruginosa clinical isolates.

      Post-microbial therapeutics is proposed here as an integrative, function-centered framework rather than a new therapeutic class. It asks whether a defined microbial perturbation can produce a reproducible change in a microbial function, biochemical output, and clinically relevant host phenotype. Bacteriophages provide a perturbation model because their host dependence permits strain-selective intervention, but the framework also distinguishes between whole phages and engineered phages, lysins, depolymerases, delivery systems, and combination products. A central requirement is that a microbial module must be defined by experimentally testable functional contribution rather than by statistical co-occurrence alone. Computationally inferred modules are therefore treated as hypotheses until supported by perturbation, reconstruction, removal/add-back, flux, or rescue experiments. Evidence reviewed across infection, gastrointestinal, biofilm, and cardiometabolic contexts shows a recurring pattern: phage exposure can alter bacterial abundance, resistance phenotypes, community interactions, and metabolism, but the strength of evidence diminishes as claims shift from bacterial killing to ecosystem restoration and host benefit. Engineering and delivery technologies can improve targeting or exposure, yet they introduce additional constraints in genetic stability, resistance, formulation, pharmacology, and regulation. The framework is consequently best viewed as a testable translational architecture that connects intervention to function and outcome while separating established evidence from emerging hypotheses.

      The rapid emergence of antimicrobial resistance poses a serious challenge to both human and veterinary medicine highlighting the urgent need to develop alternative antimicrobial strategies. Phage therapy has regained attention as a promising approach. However, its application in veterinary practice remains relatively limited. Most existing literature reviews focus on natural phage therapy or the development of individual technologies, and there is a lack of comprehensive analysis regarding the clinical translation of next-generation phage technologies-which have advanced rapidly in recent years-into veterinary medicine. This literature review provides a systematic review of the research progress on phages as an alternative to antimicrobial drugs in the veterinary field, with a particular emphasis on application characteristics, treatment strategies, and challenges across different animal species and infection scenarios. It systematically integrates the next-generation technologies that have driven the recent advancement of phage therapy, elucidating their potential applications in veterinary infection prevention and control from three aspects: (i) enhancing antimicrobial efficacy, (ii) expanding the types of antimicrobial formulations, and (iii) optimizing in vivo delivery performance. This provides a new perspective for the systematic integration and clinical translation of next-generation phage technologies in the veterinary field. Building on this foundation, the review article further proposes an artificial intelligence-based precision phage therapy strategy. By integrating pathogen identification, intelligent phage matching, rational phage design, and dynamic optimization of the treatment process, this approach offers new insights into achieving the precise, standardized, and large-scale application of phage therapy in veterinary medicine.

      Bacteria have evolved diverse anti-phage defence systems to counter the constant threat of viral infection. Like all immune systems, these defences must accurately detect infection while avoiding inappropriate activation that could harm the uninfected host. Recent years have witnessed a rapid expansion in the discovery of bacterial immune mechanisms, yet fundamental questions remain about how these systems recognize phage invasion. What molecules or events are reliable indicators of infection? How do the sensory mechanisms underlying immunity ensure rapid and robust activation? And what evolutionary trade-offs do phages face when mutating to evade detection? In this Review, we examine the experimental approaches used to identify phage-based triggers and organize known triggers into three classes: phage nucleic acids, phage proteins and perturbations to host processes. For each class, we summarize current evidence and highlight emerging principles that connect diverse defence mechanisms. By focusing on sensing rather than downstream responses, we aim to provide a cohesive framework for understanding how bacteria discriminate self from non-self, a challenge universal to immune systems across all domains of life.

      Bacteria and phages are engaged in a persistent evolutionary struggle. To survive constant phage predation, bacteria have evolved a highly diverse and multi-layered immune arsenal that determines the success of therapeutic phage infection. Bacterial defenses include receptor blockade, DNA restriction systems, CRISPR-Cas adaptive immunity, and secondary messenger signaling systems that induce effector-mediated cell death. Recent mechanistic advances have elucidated systems such as Thoeris (gcADPR-activated SIR2 effectors depleting NAD⁺), CBASS (cyclic nucleotide-activated effectors disrupting cell integrity), and toxin-antitoxin systems (e.g., ShosTA disrupting purine metabolism). These defenses directly impact phage therapy outcomes. However, phages have evolved sophisticated countermeasures, including RNA-based anti-CRISPRs and enolase hijacking, while engineered phages carrying synthetic anti-defense proteins are being developed to overcome bacterial immunity. The present review integrates defense system classification, phage counter-defense evolution, and their associations with phage therapy outcomes within a unified framework for phage selection and engineering. This review provides a scientific basis for defense-informed phage selection, rational phage engineering, and the design of future clinical trials against multidrug-resistant infections.

       BACKGROUND: Diabetic foot osteomyelitis (DFO) is a serious complication of diabetic foot ulcers and is associated with increased risk of amputation, morbidity, and mortality. Bone biopsy remains the most definitive diagnostic modality, yet controversy persists over its diagnostic utility This study reviews the diagnostic concordance of histopathology and microbiology in bone biopsy specimens from patients with DFO and examines the clinical implications of the findings.
    METHODS: A systematic review was conducted using PubMed, Medline, CINHAL, Cochrane Library, and Google Scholar. Studies included adult patients with DFO in whom bone biopsy specimens underwent both histopathological and microbiological analysis. Five core studies met the eligibility criteria. Data on study design, setting, population, diagnostic methods, concordance rates, and outcomes were extracted and synthesized utilising a quantitative narrative synthesis.
    RESULTS: Across the five studies (n = 308 patients), histopathology and microbiology showed modest concordance, with mean rates of concordant positive results of 43.4% and common discordant findings. Histopathology demonstrated higher specificity, while microbiology had higher sensitivity, ranging from 70% to 83.9% but greater susceptibility to contamination. Positive histopathology was more strongly associated with the need for revision surgery or extended antibiotic therapy.
    DISCUSSION: Histopathology appears to offer superior diagnostic specificity, whereas microbiology provides valuable information for antimicrobial management. Frequent discordance underscores the importance of interpreting results in a clinical context. Further robust, prospective studies are needed to clarify the optimal diagnostic approach and standardise definitions.

       Background: Increasing use and abuse of antibiotics has led to a rise in multidrug resistant organisms (MDRO) isolates among infected diabetic foot ulcers (DFUs) and is seen in more than half of all diabetic foot infection cases. This study aimed to identify risk factors for MDRO infection since there are no Filipino studies currently available to establish an association.
    Methodology: A cross-sectional, analytical study was conducted to evaluate risk factors for MDRO in DFUs. Adult patients admitted in a tertiary hospital from January 2019 - December 2023 for DFU were included in the study. Based on retrospective chart review, patients with DFU described to be infected with accompanying superficial or deep wound cultures were studied. Patients were classified under the MDRO-positive group if their cultures reported any of the following organisms: methicillin-resistant Staphylococcus aureus (MRSA), extended-spectrum beta-lactamases (ESBL), amp C and carbapenamases-producing Enterobacteriaceae, Metallo-beta-lactamases (MBL)-producing Pseudomonas, Acinetobacter species, or any isolate with at least one drug resistance in three different antibiotic classes. Those who did not fall into this definition, including cultures without growth, were classified under the MDRO-negative group. Clinical risk factors and pertinent laboratory findings were obtained from their data.
    Results: One hundred fifty-one (151) patients were included in the study and 52 (34.43%) patient had MDRO isolates. The most common isolates seen were Klebsiella pneumoniae for gram-negative organisms and Staphylococcus aureus for gram-positive organisms. For gram-negative isolates, erythromycin had the most resistance at 17.53% followed by oxacillin and clindamycin both at 13.4%. For gram-positive isolates, highest resistance were seen with ampicillin at 18.99% followed by cefuroxime at 13.57% and amoxicillin-clavulanate at 11.63%.Higher ulcer grade (Crude OR = 1.11 [95% CI 1.00 - 1.23], p-value 0.04; Crude OR = 1.29, [95% CI 1.04 - 1.60], p-value 0.02), as well as previous admission for diabetic foot ulcer (Crude OR = 2.28, [95% CI 1.10 to 4.73], p-value 0.04) were associated with multidrug resistance. Logistic regression showed that only a previous admission had significant association for MDRO positivity (Adjusted OR = 3.00 [95% CI: 1.04 - 8.62], p-value 0.04).
    Conclusion: There is a high burden of multidrug resistant organism infection in diabetic foot ulcers with significant association in higher ulcer grades. A previous admission for diabetic foot ulcer significantly increases the odds for MDRO infection in succeeding diabetic foot infections.

      Temperate bacteriophages are increasingly recognized as important drivers of microbial evolution. However, their role in mediating competition among members of the same species during infection remains poorly defined. Pseudomonas aeruginosa (Pa), an opportunistic pathogen associated with acute and chronic infections, frequently exhibits clonal dominance within infected individuals, suggesting the existence of effective mechanisms for excluding conspecific competitors. Here, we investigate the contribution of temperate bacteriophages to intraspecies competition among clinical Pa isolates. Screening of filtered cell-free supernatants from a diverse panel of clinical strains revealed that cell-independent antagonism is widespread, with most strains inhibiting the growth of at least one other Pa isolate. Susceptibility was strongly associated with twitching motility, a type IV pili-dependent phenotype, which also serves as the primary receptor for most Pa bacteriophages. Plaque assays confirmed the presence of infectious phage particles with strain-specific host ranges. Exposure of susceptible strains to infective phages resulted in the emergence of phage-induced small colony variants (pSCVs) that retained and propagated the acquired phages and associated inhibitory capacity. Whole-genome sequencing revealed extensive prophage diversity and mosaicism across clinical isolates, supporting a model in which poly-lysogeny expands competitive potential. Using isogenic pSCV systems and murine wound infection models, we demonstrate that acquisition of specific temperate phages confers a competitive advantage both in vitro and in vivo. These findings establish temperate bacteriophages as dynamic ecological weapons that shape intraspecies competition providing a mechanistic basis for clonal dominance during Pa infection and highlighting the broader role of prophages in structuring microbial populations.

       Introduction: The growing threat of multidrug-resistant (MDR) Pseudomonas aeruginosa (P. aeruginosa) has created an urgent need for novel therapeutic strategies to combat refractory lung infections. The limited efficacy of traditional antibiotics against this pathogen highlights the necessity of developing alternative treatments. Our study aims to develop a broad-spectrum bacteriophage cocktail suitable for nebulization and to evaluate its antibacterial efficacy and safety in respiratory infections caused by MDR P. aeruginosa.
    Methods: We constructed a seven-phage cocktail by selecting phages with complementary host ranges, strong lytic activity, and different receptor targets. The antimicrobial and anti-biofilm activity of the cocktail was assessed in vitro against clinical MDR P. aeruginosa isolates. The therapeutic efficacy and safety were further investigated in a murine pneumonia model following nebulized administration.
    Results: The phage cocktail demonstrated lytic activity against nearly 90% of 152 clinical P. aeruginosa isolates, indicating broad coverage. Compared to single phages or antibiotics, the cocktail showed superior activity in both inhibiting and disrupting biofilms. In the murine pneumonia model, nebulized phage therapy improved survival, reduced bacterial burdens in lung and liver, and alleviated infection-related histopathological damage. Safety assessment revealed no obvious hematological, biochemical or histopathological abnormalities in both acute and long-term administration.
    Conclusion: High-dose nebulized administration of this phage cocktail reduced bacterial burden and showed favorable tolerability in a murine model of MDR P. aeruginosa pneumonia. These findings provide preclinical evidence supporting further evaluation of inhaled phage cocktails as a potential therapeutic strategy for refractory respiratory infections.

      Diabetic foot ulcers (DFU) are a dangerous side effect of diabetes mellitus that significantly impairs a patient's health and standard of living. For efficient treatment and to avoid serious outcomes like infections and amputations, DFUs must be detected promptly and precisely. This paper introduces a novel Deep Learning Strategy-based framework for Diabetic Foot Ulcer Detection (DLS-DFUD). The DLS-DFUD framework involves four key steps: preprocessing, segmentation, extraction of features, and classification. The detection process starts with acquiring the input image, which is then preprocessed using Wavelet Transform-based Wiener Filtering (WT-WF) to minimize noise and improve image quality. The cleaned image is subsequently segmented with a Middle Convolutional layer Assisted U-Net (MCA-U-Net) model, precisely distinguishing DFU regions from healthy tissue. From this segmentation, various features are extracted, including Median Binary Patterns (MBP), Modified Pixel Computation in Multi-Texton (MPC-MT), shape features, and statistical features to capture crucial ulcer characteristics.

       BACKGROUND: Diabetic foot ulcers (DFUs) are characterized by impaired healing and infection, but microbial signatures linked to glycemic status and their therapeutic relevance remain unclear.
    PURPOSE: To identify DFU taxa associated with glycemic status and test whether microbiome-guided prioritization can inform evaluation of Tanshinone IIA (Tan IIA).
    STUDY DESIGN: Clinical metagenomic discovery followed by in vitro functional and multi-omics analyses, biophysical studies, and in vivo evaluation.
    METHODS: Wound samples from 54 DFU patients underwent HbA1c-stratified shotgun metagenomics. A prioritized patient-derived Corynebacterium striatum isolate was assessed for Tan IIA antibacterial and antibiofilm activity, multi-omics responses, and candidate-protein binding. Topical Tan IIA was tested in non-inoculated and C. striatum-inoculated diabetic wounds.
    RESULTS: C. striatum was enriched in higher-HbA1c wounds and positively associated with continuous HbA1c (β = 0.422, 95% CI 0.095-0.748; P = 0.011; q = 0.064). Tan IIA inhibited the isolate (MIC = 64 μ g/ml), reduced biofilm biomass, and induced stress, redox, cell-envelope, and metabolic responses. SPR supported binding to MurD and TrxB. On day 14, wound closure was significantly greater in inoculated wounds (93.40% vs. 78.80%; adjusted P = 0.0187). In inoculated wounds, Tan IIA reduced EUB338-positive bacterial signal and viable counts versus vehicle (8.587 vs. 8.847 log10 CFU/g; adjusted P =  0.0480).
    CONCLUSION: HbA1c-stratified metagenomics prioritized C. striatum as a glycemic-status-associated candidate. These findings support microbiome-guided preclinical evaluation of plant-derived Tan IIA as a topical candidate for infected DFUs.

      Diabetic foot ulcers (DFUs) affect approximately 18.6 million people worldwide each year. Abnormal plantar pressure during the perioperative period impairs wound healing and promotes ulcer recurrence. Although offloading interventions are fundamental to DFU management, available evidence remains fragmented, and clinical implementation lacks standardization, particularly in perioperative settings. This systematic review and evidence synthesis aimed to systematically retrieve, appraise, and synthesize the best available evidence on perioperative offloading management for DFU patients and to provide evidence-based recommendations for clinical nursing practice. A systematic search following the "6S" evidence pyramid model was conducted across PubMed, Web of Science, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang, and Chinese Biomedical Literature Database (CBM) databases, as well as professional society websites, from January 2015 to March 2025. Eligible publication types included clinical guidelines, expert consensus statements, clinical decisions, evidence summaries, and systematic reviews. Quality appraisal used the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument for guidelines and Joanna Briggs Institute (JBI) critical appraisal tools for systematic reviews and expert consensus. Evidence was graded using the JBI Evidence Grading System (2014 version). Fifteen publications were included: 8 guidelines, 2 expert consensus statements, and 5 systematic reviews. Thirty-one evidence items were summarized across seven domains: perioperative risk screening and assessment, multidisciplinary team composition, surgical strategy selection, offloading principles, preoperative offloading, postoperative offloading, and health education with monitoring. Evidence levels ranged from 1 to 5, with the majority at Level 5. This systematic review synthesizes comprehensive evidence on perioperative offloading management in patients with DFU. Healthcare providers should contextualize evidence selection based on clinical settings and individual patient characteristics to optimize wound outcomes and quality of life.

      Chronic wounds remain a major healthcare challenge because persistent inflammation, biofilm formation, oxidative stress, protease imbalance, hypoxia, and impaired angiogenesis prevent progression through normal healing. Conventional wound dressings provide passive protection but cannot continuously monitor the dynamic wound microenvironment or deliver adaptive therapy. Unlike previous reviews that independently summarize wound biosensors, responsive biomaterials, or drug-delivery systems, this review critically integrates the complete closed-loop paradigm of intelligent wound management, from single- and multi-stimuli-responsive sensing to AI-assisted autonomous therapeutic intervention. Chemical and physical sensing modalities are comparatively evaluated based on analytical performance, selectivity, clinical readiness, and translational limitations, while multi-responsive logic-gated platforms are assessed against conventional single-stimulus systems. The review further synthesizes available human clinical evidence, compares fabrication strategies and manufacturing scalability, and discusses regulatory pathways governing combination products, Software as a Medical Device, and AI-enabled wound care. Particular emphasis is placed on AI model development, data quality, validation, bias mitigation, and cybersecurity requirements for safe clinical deployment. Finally, major barriers including material scalability, long-term biocompatibility, sensor robustness, standardized clinical validation, and regulatory governance are critically analyzed to establish a translational framework for developing clinically reliable, intelligent smart bandages capable of precision management of chronic wounds.

      Diabetic foot disease is a complication of diabetes mellitus, impacting morbidity, quality of life, and healthcare costs. Its clinical assessment is fragmented across multiple classification systems (SINBAD, IDSA), hindering multidisciplinary communication. The Diabetic Foot Status (DFS) is a new clinical classification based on the latest guidelines from the International Working Group on Diabetic Foot (IWGDF). It facilitates the classification of diabetic foot into three states: «Green,» «Amber,» and «Red,» also incorporating the degree of infection and the predominant origin of the lesion: neuropathic, ischemic, or mixed. The DFS is an innovative, evidence-based classification that facilitates multidisciplinary communication, in clinical practice.

       Purpose: To explore the information quality requirements of artificial intelligence generated patient education materials for diabetic foot ulcers from the perspectives of patients and nurses.
    Patients and Methods: This single-center qualitative study was conducted at the Fifth Affiliated Hospital of Guangxi Medical University, China, from November 2025 to June 2026. Maximum-variation purposive sampling recruited 15 hospitalized patients with diabetic foot ulcers and 10 nurses. Saturation was assessed separately for each group and defined as no new codes, categories, or relevant insights. It was reached after 13 patient and 8 nurse interviews, with two additional interviews per group for confirmation. Face-to-face semi-structured interviews used standardized artificial intelligence generated diabetic foot ulcer education material as a discussion stimulus. Data were analyzed using directed content analysis guided by Wang and Strong's information quality framework.
    Results: Five themes and 17 subthemes were identified. Four themes mapped to Wang and Strong's framework: intrinsic information quality (accuracy, believability, objectivity, and reputation); contextual information quality (relevancy, completeness, timeliness, appropriate amount of data, and value-added); representational information quality (ease of understanding, interpretability, consistent representation, and concise representation); and accessibility information quality (accessibility and access security). An additional specific theme comprised clinical safety and actionability. Both groups valued reliable, relevant, understandable, and accessible information, but their priorities differed: nurses emphasized clinical accuracy, professional review, and the risks of unsafe recommendations, whereas patients prioritized relevance to current wound-care needs, ease of understanding and access, and clear guidance for self-care.
    Conclusion: Patients and nurses showed different but complementary priorities. Clinical safety and actionability extend conventional information quality considerations. Artificial intelligence may support educational content generation. However, a professional review is necessary for clinically sensitive information, and patient input is essential to ensure usability. Future studies should refine and validate these requirements across settings and user groups.

       OBJECTIVES: Emerging evidence suggests a link between psoriasis (PSO), psoriatic arthritis (PSA), and periodontitis (PE), similar to other systemic conditions. This study aimed to evaluate the levels of Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia, Prevotella intermedia, and Aggregatibacter actinomycetemcomitans (qPCR), as well as salivary biomarkers RANKL, OPG, Survivin, and IL-17 (ELISA) in individuals with PSO and PSA, compared to non-psoriatic controls with and without PE.
    SUBJECTS AND METHODS: From a case-control study (n = 655), 192 non-smokers and non-diabetics were randomly selected and divided into six gender-matched groups (n = 32 each): control, PSO, and PSA, with and without PE.
    RESULTS: Higher counts of P. gingivalis, T. forsythia, and T. denticola were found in individuals with PE, particularly in PSA + PE and PSO + PE groups, along with significant intergroup differences in IL-17 and survivin, with higher levels in PSA than PSO and controls. In PSA + PE individuals, OPG, IL-17, and survivin were significantly increased. Positive correlations were observed between RANKL, IL-17, survivin, and clinical periodontal parameters, with negative correlations for OPG (p < 0.001).
    CONCLUSIONS: Psoriatic individuals with PE show higher levels of classical red-complex periodontopathogens and heightened inflammatory biomarker levels, especially in PSA. These findings highlight the need for integrated care between dermatologists and periodontists.

      Predicting the outcomes of bacteria-phage interactions is a central challenge in microbial ecology, particularly across heterogeneous host environments. Evolutionary relatedness among bacteria can explain variation in phage susceptibility in vitro, but it remains unclear whether this predictive relationship persists in complex host environments and to what extent relatedness also explains variation in other bacterial traits, such as virulence. Here, we used an in vivo infection model to quantify how bacterial phylogeny and host environmental context mediate bacterial virulence and bacteria-phage interactions. We infected 4,608 Galleria mellonella larvae with 64 phylogenetically diverse Staphylococcaceae isolates, both with and without co-inoculation of the bacteriophage ISP, and recorded mortality and melanisation over 24 hours. We found that bacterial virulence varied among Staphylococcaceae strains and that a large proportion of this variation could be explained by the evolutionary relationships between bacteria, indicating that phylogeny may be useful in predicting bacterial virulence. The addition of phage significantly improved the survival of G. mellonella larvae, with an average 15.2% increase in endpoint survival and 10.1% reduction in endpoint melanisation across Staphylococcaceae strains. Unlike previous in vitro studies, the evolutionary relationships between bacterial isolates could not explain variation in in vivo phage efficacy across Staphylococcaceae. Concurrently, we found no evidence of a correlation between in vivo and in vitro measures of phage efficacy across bacterial isolates, highlighting the importance of the host environment in shaping bacteria-phage dynamics.

      Respiratory tract infections (RTIs) remain a leading cause of global morbidity and mortality, and their clinical management is increasingly undermined by the biofilm mode of growth of major respiratory pathogens. Biofilm formation confers profound tolerance to conventional antibiotics through the extracellular polymeric substance (EPS) matrix, metabolic adaptations, and rapid acquisition of resistance, underscoring the need for new therapeutic strategies. Patents offer a valuable and timely insight into emerging technologies with translational potential. In this review, we analyse patents published between 2000 and 2025 that could be explored for the management of microbial biofilms related to respiratory infectious diseases. Using the WIPO Patentscope database, we identified 135 relevant patents and examined trends in patent activity, innovation classes, and proposed therapeutic modalities. These patents encompass a broad landscape of biological, chemical, and device-based strategies-including enzymes, peptides, nanoparticles, phages, probiotics, repurposed drugs, and engineered delivery systems-many of which demonstrate efficacy against biofilms formed by Streptococcus pneumoniae, Staphylococcus aureus, Pseudomonas aeruginosa, and other key respiratory pathogens. This 25-year patent analysis highlights a maturing innovation pipeline and reveals promising therapeutic directions for overcoming biofilm-associated recalcitrance in RTIs, offering a foundation for future drug development and clinical translation.

      Poor oral health is commonly linked to cardiovascular disease through the established association between periodontitis and systemic inflammation. This relationship is usually explained by bacterial dissemination from periodontal pockets, lipid dysregulation, and oxidative stress, all of which may contribute to endothelial dysfunction and atherothrombotic changes. However, this conventional framework leaves an important question unresolved: if the main infectious and inflammatory niches are removed after complete tooth loss (edentulism), how does edentulism remain associated with increased cardiovascular risk? Epidemiological studies consistently show that edentulous individuals continue to have elevated cardiovascular morbidity and mortality, yet mechanistic explanations for this association remain underdeveloped. Therefore, this paper proposes a plausible biological model to explain persistent cardiovascular risk in edentulism. The model argues that, after tooth loss, the oral environment is not biologically inert but rather reorganised into a distinct ecological and immunological niche shaped by dentures, altered salivary flow, nutrient changes, microtrauma, and residual soft-tissue biofilms. The tongue, oral mucosa, saliva, and denture surfaces may support persistent colonisation by Porphyromonas gingivalis and other organisms within distinct soft-tissue and prosthesis-associated biofilms. The model further proposes that local ecological stress, altered nutrient availability, and cytokine changes may favour regulatory T-cell-associated immune tolerance and impair antimicrobial clearance. Microbial products and outer membrane vesicles may provide additional routes of host signalling, although persister-specific OMV production and its vascular relevance in edentulism remain unconfirmed. Persistent cardiovascular risk after tooth loss is likely multifactorial, and the proposed microbial-immune mechanism represents a complementary framework for future longitudinal, microbiological, immunological, and interventional research.

      Oral health is increasingly recognized as a critical component of systemic and neurological resilience during aging. In particular, the oral microbiome may represent a modifiable interface linking periodontal inflammation, neuroimmune activation, and the risk of neurodegenerative disorders.Emerging evidence increasingly supports a link between oral microbiome dysbiosis and the pathogenesis of neurodegenerative disorders. Chronic inflammatory conditions, such as periodontitis, are associated with systemic inflammation, which may contribute to neuroinflammation. Key oral pathogens can translocate into the systemic circulation, compromise the integrity of the blood-brain barrier, and activate microglia. Mechanisms linking oral microbiome dysbiosis to neurodegeneration include systemic inflammation mediated by pro-inflammatory cytokines, direct bacterial invasion of the central nervous system, and modulation of the oral-gut-brain axis through alterations in the gut microbiota and neuroimmune interactions. Personalized neuronutritional strategies, including dietary intake and supplementation with polyphenols, may improve oral health and reduce systemic inflammation. The interdisciplinary integration of neurology, dentistry, and neuronutrition offers new opportunities for the prevention and management of neurodegenerative disorders. Promising approaches include the development of early diagnostic biomarkers of oral dysbiosis and targeted interventions aimed at restoring microbial homeostasis. Further research is needed to clarify causal relationships and optimize strategies for modulating the oral microbiome to preserve cognitive function.

      Phage therapy has emerged as a promising alternative for combating multidrug-resistant hypervirulent Klebsiella pneumoniae (MDR-hvKP) infections. Recent advances suggest that tailoring phage cocktails based on genomic surveillance of circulating strains might yield more effective regimens (Koncz et al., 2024). Here, we combined publicly available epidemiological records with regional strain analysis to examine the distribution of the ST23-K1 lineage and to place the selected target in genomic and clinical context. Among the 227 isolates in our Henan collection, ST23-K1 accounted for 11.01% of isolates. We isolated a novel lytic phage, vB_KpnS_P10HW, from urban sewage using a clinically representative high-risk ST23-K1 MDR-hvKP strain, KH1127-5, as the host. vB_KpnS_P10HW exhibited lytic activity against K1-type K. pneumoniae isolates across four sequence types. The phage displayed rapid adsorption (80% within 10 min), a short latent period (5 min), and remarkable stability across temperature (4-60 °C) and pH (4-10) ranges. Whole-genome sequencing revealed a 49,682 bp linear dsDNA genome devoid of lysogeny, virulence, or antibiotic resistance genes. Phylogenomic analysis placed vB_KpnS_P10HW within the family Drexlerviridae, genus Webervirus. Functionally, vB_KpnS_P10HW rapidly reduced viable bacterial cells within 30 min at high multiplicities of infection and effectively disrupted preformed biofilms in a dose-dependent manner. In vivo, phage administration increased the survival rates in both Galleria mellonella and mouse infection models. These results support vB_KpnS_P10HW as a genetically safe and promising therapeutic candidate against clinically relevant ST23-K1-associated MDR-hvKP and suggest that integrating genomic epidemiological context with phage characterization may help prioritize regional targets for precision phage therapy against K. pneumoniae.

      Automated segmentation of diabetic foot ulcers (DFUs) supports clinical diagnosis, treatment planning, and longitudinal wound monitoring, but remains difficult owing to the heterogeneous appearance, irregular morphology, and cluttered backgrounds of ulcers in clinical photographs. Convolutional networks such as U-Net localise well but model long-range context poorly, whereas Vision Transformers capture global dependencies. We employ a hybrid ViT-bottleneck U-Net that combines a convolutional encoder-decoder with a Transformer bottleneck and attention-gated skip connections, and we emphasise that the contribution is a rigorously validated and explainable application rather than a new architecture. The model was trained on the public Foot Ulcer Segmentation Challenge (FUSeg) dataset with a hybrid Dice and cross-entropy loss, and all results are reported over five seeds as mean ± 95% confidence interval at a single fixed threshold. On the internal validation set it achieved a Dice of 0.8035 ± 0.0053 and an IoU of 0.7149 ± 0.0073 (HD95 = 19.74 px, ASSD = 6.12 px). A component-wise ablation showed that only the hybrid loss produced a statistically significant change in Dice (- 0.038, p < 0.001); the Transformer bottleneck, attention gates, and augmentation each had small, non-significant in-domain effects. External validation without retraining retained about 92% of internal Dice on the Advancing the Zenith of Healthcare (AZH) Wound Care Center cohort (Dice 0.7460, n = 278), while a small Medetec subset (n = 8) served only as a qualitative check, indicating partial rather than robust generalisation under domain shift. A quantitative explainability analysis found Grad-CAM more wound-localised (energy-in-mask 0.871 versus 0.102) but attention rollout significantly more faithful (p = 0.038, n = 200), showing the two are complementary. Predicted and expert wound areas agreed strongly (Pearson r = 0.944), and the model is lightweight (8.79 M parameters).

       Purpose: The treatment of diabetic foot ulcers (DFUs) remains challenging, and the benefits and safety of platelet-rich plasma (PRP) therapy are still debated. This study analyzed existing meta-analyses on PRP therapy for DFUs to identify the most reliable evidence source.
    Methods: This cross-sectional appraisal was conducted according to PRISMA 2020 guidance. PubMed, Embase, and the Cochrane Library were searched from inception to May 20, 2026, for meta-analyses comparing PRP therapy with standard or conventional care for DFUs. Only meta-analyses based exclusively on randomized controlled trials (RCTs) were included. Methodological quality was assessed using AMSTAR, evidence level was classified according to the Oxford Levels of Evidence, and discordant findings were examined using the Jadad decision algorithm.
    Results: Eleven meta-analyses were included in this study, all of which were categorized as Level II evidence. The AMSTAR scores ranged from 6 to 10 (median 8). The meta-analysis identified by the Jadad algorithm as the most robust source showed that autologous PRP improved complete ulcer healing rates (OR: 2.11; 95% CI: 1.55-2.86) and shortened complete healing time (MD: -19.04 days; 95% CI: -20.46 to -17.61) compared with standard care. Furthermore, the incidence of adverse events in PRP groups was not significantly different from that in standard care groups, and the results were robust in sensitivity analyses.
    Conclusion: PRP is an effective adjunctive therapy for DFUs, with no statistically significant increase in reported adverse events. However, further large-scale, high-quality trials are needed to standardize PRP preparation and administration, and to establish optimal treatment protocols.

      Ocular infections, ranging from conjunctivitis and keratitis to postoperative and device-associated endophthalmitis, remain a significant cause of preventable visual morbidity worldwide. In India and other low- and middle-income countries, the irrational use of topical and systemic antimicrobials, often without microbiological confirmation, has contributed to the emergence of multidrug-resistant ocular pathogens. Fluoroquinolone-resistant Pseudomonas aeruginosa , methicillin-resistant Staphylococcus aureus , and resistant Fusarium and Candida species are now major challenges in ophthalmic practice. The widespread availability of over-the-counter ophthalmic drops, empirical perioperative prophylaxis, and the use of steroid-antibiotic combinations exacerbate this problem. Antimicrobial stewardship (AMS) in ophthalmology, though relatively underdeveloped, is now a global priority. The Society of Antimicrobial Stewardship PractIce (SASPI) in India advocates an integrated AMS model linking diagnostic, preventive, therapeutic, and administrative strategies. For ophthalmologists, this translates into culture-guided therapy for recalcitrant or postsurgical infections, restricting the use of broad-spectrum or prolonged topical antimicrobials, enforcing asepsis during surgeries, and adopting antimicrobial auditing systems. The RED EYE AMSP model presented in this perspective provides a ten-point, ophthalmology-specific adaptation of the SASPI framework focusing on rational prescribing, evidence-based diagnostics, environmental safety, and interprofessional partnership. By embracing stewardship, ophthalmologists can preserve antimicrobial efficacy, minimize iatrogenic resistance, and contribute to the broader One Health goal of antimicrobial resistance containment.

      Bacteriophages offer promising alternatives to antibiotics for treating drug-resistant infections and engineering microbiomes, but applications are limited by challenges related to selection of phages infecting specific bacterial strains. Here we present a phylogeny-agnostic machine-learning framework predicting strain-level phage-host interactions across diverse bacterial genera from genome sequences alone. Systematically optimizing the workflow over 13.2 million training runs across six datasets (115,037 interactions, 949 bacterial strains, 518 phages), we achieved performance matching species-specific methods (AUROC 0.67-0.94) while eliminating phylogenetic constraints. Experimental validation of 1,240 predicted E. coli phage-host interactions confirmed generalizability (AUROC 0.84), while genome-wide RB-TnSeq screens verified that 68.6% of experimentally identified infection mediators were captured computationally. Model-guided cocktail design achieved up to 97.5% bacterial coverage with five phages, and up to a 3.1-fold improvement in single-phage selection over promiscuity-based selection. This platform enables rational phage-therapy design and precision microbiome engineering with applications across clinical, agricultural and industrial contexts.

       Background: Immunosuppressed patients with extensive skin barrier disruption face extraordinary risks for polymicrobial infections. The rapid, sequential emergence of multidrug-resistant (MDR) bacteremia and candidemia in such hosts constitutes a particularly lethal complication with limited therapeutic options.
    Case Presentation: We report a 74-year-old woman with refractory pemphigus vulgaris (PV), type 2 diabetes mellitus, and chronic obstructive pulmonary disease who developed a cascade of MDR infections over a 14-day hospitalization. Following initial methicillin-resistant Staphylococcus aureus (MRSA) skin colonization, she developed Serratia marcescens bacteremia, subsequently complicated by wound superinfection with carbapenem-resistant Acinetobacter baumannii (CRAB) and multiple Candida species, including the rare yeast Kodamaea ohmeri. Despite sequential antimicrobial escalation-from piperacillin-tazobactam/linezolid to meropenem/amikacin, and finally caspofungin-her condition deteriorated with diabetic ketoacidosis, culminating in the family's decision to pursue discharge with comfort care based on the patient's previously expressed wishes; she died three days later. K. ohmeri demonstrated reduced fluconazole susceptibility (MIC = 8 µg/mL), highlighting the diagnostic and therapeutic challenges posed by emerging fungal pathogens.
    Conclusion: This case starkly illustrates the catastrophic potential of rapid, sequential MDR infections in profoundly immunocompromised hosts with skin barrier defects. It underscores the critical importance of early microbiological surveillance, the clinical urgency of dynamic antimicrobial stewardship, and the imperative for multidisciplinary management to navigate the irreconcilable conflict between necessary immunosuppression and life-threatening infection.

      Biofilms are highly organized microbial communities that adhere to living or nonliving surfaces and are enclosed in a self-produced extracellular matrix. Their tolerance against antimicrobial agents and host defenses makes them a major challenge across clinical, industrial, and environmental fields. This review offers an in-depth analysis of biofilm formation, structure, and dispersal mechanisms, highlighting the genetic and molecular regulators that underlie their development. This review also provides extensive details of advanced and investigative strategies for biofilm eradication, including antibody-based approaches, photodynamic therapy, nanotechnology-driven solutions, surface modification of biomaterials, biological and phage-based approaches, the integration of smart and responsive systems, and host immune modulation methods. By integrating recent advances in imaging, experimental modeling, therapeutic innovations, artificial intelligence, and machine learning models, this work highlights not only the complexity of biofilm biology but also the research and development prospects for effective intervention tools. Finally, this review discusses major translational challenges associated with moving antibiofilm strategies from laboratory research to clinical and device-related applications. This review also proposes practical guidelines to overcome these challenges. Overall, the review highlights the requirements for interdisciplinary collaboration across microbiology, materials science, clinical medicine, and regulatory frameworks. Unlike traditional descriptive reviews, this review adopts a decision-oriented framework, providing clear research guidance for researchers.

       INTRODUCTION: Osteomyelitis presents with heterogeneous clinical, etiological, and microbiological characteristics depending on anatomical location. While foot osteomyelitis is commonly associated with diabetic foot infections and contiguous spread, non-foot osteomyelitis often arises from post-traumatic, hematogenous, or postoperative causes. However, direct comparative analyses between these two entities remain limited.
    MATERIALS AND METHODS: A retrospective analysis was conducted on 202 adult patients who underwent surgical treatment for osteomyelitis between 2011 and 2026. Patients were divided into foot (n = 89) and non-foot (n = 113) osteomyelitis groups. Clinical, etiological, microbiological, and treatment-related variables were compared. Only intraoperatively obtained deep tissue and/or bone cultures were included.
    RESULTS: Patients with foot osteomyelitis were older and had a significantly higher prevalence of diabetes mellitus (49.4% vs. 5.3%, p < 0.001), which was identified as an independent predictor of foot osteomyelitis (OR 14.15, 95% CI 4.32-46.42; p < 0.001). Infections in foot osteomyelitis predominantly developed via contiguous spread (73.0%), whereas non-foot osteomyelitis showed more heterogeneous etiologies, including post-traumatic and hematogenous causes (p < 0.001). Microbiologically, Staphylococcus aureus was the most common pathogen in non-foot osteomyelitis, while foot osteomyelitis demonstrated a more diverse distribution with higher rates of polymicrobial infections. Amputation was significantly more frequent in the foot group (50.6% vs. 15.9%, p < 0.001), whereas antibiotic-loaded cement use was more common in non-foot osteomyelitis (p < 0.001).
    CONCLUSIONS: Foot and non-foot osteomyelitis differ significantly in clinical, etiological, and microbiological characteristics. These findings suggest that foot and non-foot osteomyelitis differ in their clinical, etiological, and microbiological characteristics and may require different diagnostic and therapeutic approaches.

      The diagnosis and treatment of severe burns and complex wounds require the coordinated management of local tissue injury, systemic pathophysiological changes, and sequential clinical interventions. Existing diagnostic and treatment pathways can support bedside evidence-based decision-making and allow clinicians to adjust treatment as a patient's condition evolves. However, limitations remain in the consistency of prehospital and primary-care assessments, the longitudinal integration of multimodal information, and the use of risk prediction results to support clinical decisions. Based on the clinical requirements of severe burn and complex wound care and the available evidences form artificial intelligence studies, this expert commentary examines the capability boundaries of current care pathways, the potential clinical benefits for different users, and the conditions required to extend risk prediction to constrained causal inference. We propose a full-course dynamic diagnostic and treatment framework comprising wound assessment, systemic monitoring, and clinical intervention. Standardized image analysis is used to assess wound area, depth, necrosis, infection, and healing trajectories. Time-series models integrate vital signs, laboratory measurements, inflammatory and infectious markers, metabolic and coagulation status, and organ function to continuously monitor the patient's systemic condition. At the same time, clinical interventions, including fluid resuscitation, anti-infective treatment, debridement and wound coverage, nutritional support, and rehabilitation, are aligned along a unified timeline to preserve the temporal relationships among changes in patient status, intervention timing, and clinical outcomes. Risk prediction is used to estimate potential clinical outcomes that may occur under the existing diagnostic and treatment pathways, whereas counterfactual simulation must be based on explicit causal assumptions, applicability conditions, uncertainty estimates, and boundaries of responsibility, and its results cannot be used directly as treatment prescriptions. The clinical value of artificial intelligence should be established through prospective studies that directly compare the effects of clinicians' independent judgments with those of their artificial intelligence-assisted judgments. In addition to discrimination, evaluation should include assessment time, inter-clinician agreement, calibration, warning lead time, alert and workflow burden, changes in clinical decisions, patient safety, and clinical outcomes. Addressing the capability boundaries of current care pathways, intelligent wound assessment, systemic risk monitoring, causal inference, and translational implementation and governance, this article discusses the pathways and boundaries of artificial intelligence integration into full-course diagnosis and treatment for patients with severe burns and wounds requiring repair.

       Background: Antimicrobial resistance (AMR) is a growing global public health threat, particularly in low- and middle-income countries (LMICs), where delayed antimicrobial susceptibility testing (AST) and limited diagnostic capacity complicate timely treatment and antimicrobial stewardship (AMS). Although large-scale surveillance programmes routinely collect antimicrobial susceptibility data, these datasets remain underutilised for predictive analytics.
    Methods: We developed a surveillance-driven machine learning (ML) framework using isolate-level data from African sites participating in the Pfizer Antimicrobial Testing Leadership and Surveillance (ATLAS) programme between 2019 and 2023. Seven antibiotic-specific Extreme Gradient Boosting (XGBoost) models were developed to predict antimicrobial susceptibility using routinely collected microbiological, demographic, clinical, and geographical metadata. Model development included structured data preprocessing, RandomOverSampler-based class balancing restricted to the training data, hyperparameter optimisation using stratified cross-validation, and evaluation on a held-out test dataset. A rule-based MIC interpretation system and interactive dashboard were developed to demonstrate implementation of the analytical workflow.
    Results: The antibiotic-specific models demonstrated moderate predictive performance, with test accuracies ranging from 57% to 76%. Ceftazidime-Avibactam achieved the highest test accuracy (76%), followed by Gentamicin (65%) and Imipenem (64%), while Amikacin showed the lowest performance (57%). Feature-importance analysis identified bacterial species as consistently among the most influential predictors. In contrast, bacterial family, country of isolate collection, specimen source, clinical specialty, and demographic characteristics contributed to varying degrees across antibiotics. Performance was generally stronger for the more frequently represented susceptible class than for intermediate and resistant isolates.
    Conclusion: Routinely collected AMR surveillance data can support antibiotic-specific ML predictions without requiring genomic sequencing or detailed patient-level clinical information. This study provides a proof-of-concept framework for surveillance-driven predictive analytics that could complement conventional AMR surveillance and AMS. External validation, calibration, prospective clinical evaluation, and implementation studies are required before routine deployment.

       Background: Antimicrobial resistance (AMR) is a leading global health threat requiring coordinated surveillance across human, animal, environmental, and genomic systems. Machine learning is increasingly applied to AMR data, yet its contribution to actionable surveillance intelligence, rather than prediction alone, remains poorly defined.
    Objective: To map how machine-learning approaches generate AMR surveillance intelligence, to characterise their validation and implementation maturity, and to propose a framework distinguishing technical prediction from actionable surveillance intelligence.
    Methods: We conducted a scoping review following JBI methodology and PRISMA-ScR reporting. PubMed/MEDLINE, Scopus, and Web of Science were searched from January 2015 to May 2026 for studies applying machine learning or related methods to AMR surveillance intelligence. Two reviewers independently screened and charted records. Of 1,985 records, 66 met eligibility and formed the working evidence base; 41 studies (40 core empirical and one supporting preprint) were appraised against TRIPOD+AI- and PROBAST-aligned reporting, validation, and implementation-readiness domains.
    Results: Machine learning was applied across five clusters: clinical and electronic-health-record risk prediction and decision support; genomic and whole-genome-sequencing prediction; MALDI-TOF-based rapid resistance prediction; wastewater and metagenomic surveillance; and environmental, animal, food-chain, and One Health early warning. Prediction and risk stratification predominated, but validation maturity was limited: most studies were retrospective or internally validated, with few using external, cross-country, temporal, prospective, or drift-focused evaluation. On appraisal, discrimination was reported in 31 of 41 studies (76%) and explainability in 26 (63%); by contrast, external or temporal validation was present in only 15 (37%), calibration in 5 (12%), prospective evaluation in 1 (2%), and operational deployment with measured clinical or public-health impact in a single study (2%).
    Conclusion: Machine learning can support AMR surveillance intelligence across clinical, genomic, diagnostic, environmental, and One Health settings, but the evidence demonstrates technical feasibility far more convincingly than operational readiness. Realising this transition will require external and prospective validation, calibration and drift monitoring, transparent and equitable reporting, workflow integration, and explicit linkage of model outputs to clinical and public-health action. We propose a One Health AMR Surveillance Intelligence Framework to organise this shift from data generation toward actionable, adaptive surveillance intelligence.
