A 57-year-old man presented with high fever and diarrhea. A blood culture revealed the presence of a Group C nontyphoidal Salmonella (NTS) isolate. On Salmonella serotyping, the isolate was identified as Salmonella enterica serovar Virchow. Its sequence type was determined to be ST16 by sequence analysis of 7 different housekeeping genes. The bla group 1 and bla genes were amplified using multiplex PCR assay for detecting extended-spectrum β-lactamases (ESBL) genes. Sequences of both amplicons were respectively identical to CTX-M-15- and TEM-1-encoding genes. Since NTS is a cause of foodborne illness outbreaks in communities and an important cause of community-acquired bloodstream infection, clinicians should consider ESBL- or AmpC-producing NTS species in the differential diagnosis.

Introduction: Since the dawn of the new millennium, Candida species have been increasingly implicated as a cause of both healthcare-associated as well as opportunistic yeast infections, due to the widespread use of indwelling medical devices, total parenteral nutrition, systemic corticosteroids, cytotoxic chemotherapy, and broad-spectrum antibiotics. Candida tropicalis is a pathogenic Candida species associated with considerable morbidity, mortality, and drug resistance issues on a global scale.

Introduction: Invasive candidiasis is an important cause of nosocomial infection and recent studies have shown an increase in the number of cases during the coronavirus disease 2019 (COVID-19) pandemic. The present study aimed to evaluate the epidemiology and incidence of invasive candidiasis before and during the COVID-19 pandemic at a reference tertiary hospital in Brazil.
Methodology: A retrospective observational study was performed with 148 patients infected with Candida spp.

Objective: Early diagnosis of intensive care unit-acquired weakness (ICUAW) is crucial for improving the outcomes of critically ill patients. Hence, this study was designed to identify predisposing factors for ICUAW and establish a predictive model for the early diagnosis of ICUAW.
Methods: This prospective observational multicenter study included septic patients from the comprehensive ICUs of West China Hospital of Sichuan University and 10 other hospitals between September and November 2023.

This study aimed to investigate the role of myosteatosis, sarcopenia, and perioperative serum biomarkers as independent predictors of major complications within 180 days following radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC). We retrospectively analyzed of 127 MIBC patients who underwent RC between 2013 and 2023 at a single institution. Preoperative body composition was assessed using CT scans at the L3 vertebral level to measure psoas muscle density (PMD), skeletal muscle density (SMD), axial muscle density (AMD), and muscle indices.
