Antibiotic synergy against <em>Staphylococcus aureus</em>: a systematic review and meta-analysis
Antimicrobial combinations have been extensively evaluated in vitro to identify synergistic combinations for clinical use. Despite the available literature, no studies comprehensively summarize the findings for antimicrobial combinations against Staphylococcus aureus. We performed a systematic review to identify synergistic combinations that may be beneficial for clinical use against S. aureus. The PubMed, Cochrane, and Web of Science databases were queried from inception to February 2024 for...
Exposome-Scale Investigation of Cl-/Br-Containing Chemicals Using High-Resolution Mass Spectrometry, Multistage Machine Learning, and Cloud Computing
Over 70% of organic halogens, representing chlorine- and bromine-containing disinfection byproducts (Cl-/Br-DBPs), remain unidentified after 50 years of research. This work introduces a streamlined and cloud-based exposomics workflow that integrates high-resolution mass spectrometry (HRMS) analysis, multistage machine learning, and cloud computing for efficient analysis and characterization of Cl-/Br-DBPs. In particular, the multistage machine learning structure employs progressively different...
In vivo validation of a smart sensor-enabled dressing for remote wound monitoring
Every second, a person with diabetes develops a foot ulcer. At least half of these wounds become infected, which dramatically increases the risk of hospitalization, amputation, and death. Wound environment pH is a possible marker of infection, however, clinical application has yet to be achieved. Herein, we introduce a hydrogel sheet dressing made out of a transparent calcium alginate body, which is embedded by a pH-sensitive color changing dye named α-naphtholphthalein that equilibrates to...
Evidence of Coxiella burnetii and Bartonella species infections among patients with persistent febrile illness in four low- and middle-income countries
CONCLUSIONS: Direct and indirect evidence of C. burnetii or Bartonella sp. infections was observed in persistent fever cases. Further studies are necessary to elucidate the burden of these diseases in LMICs.
Cytomegalovirus-Induced Colitis Presenting as Acute Appendicitis in an Immunocompetent Patient With Ulcerative Colitis
We report a rare case of cytomegalovirus (CMV) colitis presenting radiologically as acute appendicitis in an immunocompetent 71-year-old man known for ulcerative colitis. Although initial imaging revealed acute appendicitis, a lack of clinical improvement with antibiotic therapy prompted further evaluation with colonoscopy, which led to the diagnosis of CMV colitis on a background of mild ulcerative colitis flare. Most individuals infected by CMV will exhibit lifelong latency; however, the virus...
Systems analysis unravels a common rural-urban gradient in immunological profile, function, and metabolic dependencies
Urbanization affects environmental exposures and lifestyle, shaping immune system variation and influencing disease susceptibility and vaccine responses. Here, we present systems analysis of immune profiles across the rural-urban gradient, comparing rural and urban Senegalese with urban Dutch individuals. By integrating single-cell phenotyping, metabolic profiling, and functional analysis, we reveal a trajectory of immune remodeling along the gradient. This includes enrichment of proinflammatory...
Identifying patients at high risk for antibiotic treatment following hospital admission: a predictive score to improve antimicrobial stewardship measures
CONCLUSION: The PILGRIM score effectively identifies newly hospitalized patients likely to receive antibiotics, demonstrating high specificity and PPV. Its application can improve future AMS programs and trial recruitment by facilitating targeted inclusion of patients, especially in the hematological and oncological setting. Further -external and prospective- validation is needed to broaden the model's applicability.
Comparison of ciprofloxacin and aminoglycoside susceptibility testing for ceftriaxone non-susceptible Enterobacterales by disk diffusion and VITEK 2 vs. broth microdilution using updated Clinical and Laboratory Standards Institute breakpoints
CONCLUSIONS: Our findings suggest that both disk diffusion and to a greater extent the AST-N391 card for the VITEK 2 system will overcall non-susceptibility according to current CLSI breakpoints for ciprofloxacin. By contrast, the existing AST-N391 VITEK 2 card can likely be used to correctly infer susceptibility to gentamicin and tobramycin.
