Perioperative Antibiotic Prophylaxis in Pediatric Cardiac Surgery-Simple Is Better.

Pediatric cardiac surgery requires perioperative antibiotic prophylaxis (PAP) to reduce the risk of surgical site infections. However, the complexity of these procedures and the metabolic immaturity of children impede the establishment of PAP regimens that are both efficacious and in line with antimicrobial stewardship (AMS). In this study, we compared two PAP regimens: cefazolin with gentamicin (in a retrospective group) and cefazolin only (prospectively) in children undergoing elective cardiac surgery.

Prevalence of IgG antibodies against SARS-CoV-2 among healthcare workers in a tertiary pediatric hospital in Poland.

Data on the prevalence of the SARS-CoV-2 antibody in healthcare workers (HCWs) is scarce, especially in pediatric settings. The purpose of this study was to evaluate SARS-CoV-2 IgG-positivity among HCWs of a tertiary pediatric hospital. In addition, follow-up of the serological response in the subgroup of seropositive HCWs was analysed, to gain some insight on the persistence of IgG antibodies to SARS-CoV-2.

The and of Cystic Fibrosis (CF) Patient Use of Herbal Supplements Containing L. Extract: the Evidence from an In Vitro Study on CF Clinical Isolates.

The justification for the use of herbal supplements with L. extract (POE) in the case of staphylococcal lung colonization/infections characteristic for cystic fibrosis (CF), was examined in vitro. The impact of POE phenolic-rich fraction on the virulence attributes of CF-associated () clinical strains has been assessed, including pathogen adhesion, biofilm formation on native and protein-conditioned surfaces (mucin, elastin), mature biofilm eradication, staphylococcal protein A expression, α-toxin release, and adhesion to A549 cells.
