Epidemiology and Resistance Profiles of Bacteria Isolated from Blood Samples in Septic Patients at Emergency Department Admission: A 6-year Single Center Retrospective Analysis from Northern Italy.

Objectives: This study aimed to investigate the microbiological and clinical heterogeneity of community-onset bloodstream infections (BSIs) and identify features to support targeted empirical antibiotic therapy in the Emergency Department (ED).

Methods: Clinical and microbiological data from 992 BSI cases (1,135 isolates) diagnosed within 24 hours of ED admission at IRCCS Humanitas Research Hospital, Milan, Italy (January 2015-June 2022), were analyzed. Drug resistance was interpreted using EUCAST-2023.

Distinct chromosomal mutation associated with cefiderocol resistance in : a combined bioinformatics and mass spectrometry approach to unveil and validate the -acquired chemoresistance.

is a significant public health concern due to the emergence of antibiotic-resistant strains. Cefiderocol (FDC), a novel siderophore cephalosporin, has shown promise as a last-line treatment for multidrug-resistant Gram-negative bacteria. However, the emergence of -acquired FDC-resistant strains highlights the need for advanced tools to identify resistance-associated genomic mutations and address the challenges of FDC susceptibility testing.

The long Pentraxin PTX3 serves as an early predictive biomarker of co-infections in COVID-19.

Background: COVID-19 clinical course is highly variable and secondary infections contribute to COVID-19 complexity. Early detection of secondary infections is clinically relevant for patient outcome. Procalcitonin (PCT) and C-reactive protein (CRP) are the most used biomarkers of infections.

Quantitative Chest CT Analysis to Measure Short-Term Sequelae of COVID-19 Pneumonia: A Monocentric Prospective Study.

(1) Background: Quantitative CT analysis (QCT) has demonstrated promising results in the prognosis prediction of patients affected by COVID-19. We implemented QCT not only at diagnosis but also at short-term follow-up, pairing it with a clinical examination in search of a correlation between residual respiratory symptoms and abnormal QCT results. (2) Methods: In this prospective monocentric trial performed during the "first wave" of the Italian pandemic, i.
