In this study, we examine the possible association between treatment with vancomycin and colonization with extended-spectrum beta-lactamase (ESBL)-producing Klebsiella in our neonatal intensive care unit (NICU). Variables compared between newborns which developed rectal colonization and those who did not include: gestational age, birth weight, gender, and total length of hospital stay until positive stool culture or discharge, treatment with vancomycin, and positive blood culture for coagulase-negative Staphylococcus. We found that lower birth weight, younger gestational age, and treatment with vancomycin were statistically significant risk factors for gastrointestinal colonization with ESBL-producing Klebsiella. When applying a multivariate model, treatment with vancomycin, both for a full 10-day course and for a short 3-day empirical treatment, remained statistically significant. Treatment with vancomycin is a risk factor for gastrointestinal colonization with ESBL-producing Klebsiella in premature babies.

Multiple Gas-Containing Renal Stones: A Case Report.

BACKGROUND Emphysematous urinary tract infections are rare and serious conditions that are often multifactorial in etiology and may be associated with the presence of renal stones. Diagnosis can be made by finding gas within the renal collecting system or parenchyma. However, the radiographic finding of gas within a renal stone is rare and little has been published to describe the significance of this finding, its promoting factors, and management.

The increasing threat of antimicrobial-resistant bacteria, particularly Staphylococcus aureus, which rapidly develops multidrug resistance and commonly colonizes wound surfaces, demands innovative strategies. Phage-encoded endolysins offer a dual-purpose approach as topical therapies for infectious skin wounds and synergistic agents to reduce high-dose antibiotic dependence. This study explores recombinant CHAPk (rCHAPk), efficiently synthesized within 3 h, displaying broad-spectrum antibacterial activity against 11 Gram-positive strains, including resistant variants, with rapid bactericidal kinetics.

Background: Among people with cystic fibrosis (PwCF), methicillin-resistant (MRSA)-associated acute pulmonary exacerbations (APEs) have been increasing in prevalence and can cause rapid declines in lung function and increased mortality. Fortunately, since 2019, incidence has started to decline.
Objective: The purpose of this study was to evaluate if doxycycline has comparable efficacy to vancomycin for the treatment of APEs in PwCF.
