Importance: Infective endocarditis (IE) caused by Staphylococcus aureus is associated with high mortality, approximately 20% to 30%, mostly in the first month, with no improvement in recent decades. Current opinion is that antistaphylococcal penicillin and cefazolin are equally effective in treating methicillin-susceptible S aureus (MSSA) IE, and both are recommended as possible first-line treatments. Most MSSA strains carry the β-lactamase blaZ gene, and some blaZ-positive strains exhibit an inoculum effect, meaning increased minimum inhibitory concentrations at high inoculum.

Article Synopsis
  • The study investigates how bacteria adapt to patients over long hospital stays, focusing on antimicrobial resistance and metabolic changes in the gut during intensive care unit (ICU) admissions.
  • Weekly rectal swabs from ICU patients were analyzed to track the evolution of enteric bacterial populations, revealing that only a small number of patients harbored distinct strains.
  • Key findings included a persistent strain that exhibited significant changes in drug resistance, highlighting the impact of genetic mutations on bacterial behavior and patient treatment challenges.

Background: The prognosis for patients with relapse of localized rhabdomyosarcoma (RMS) remains poor, with limited evidence for optimal second-line therapy. This study describes the management and outcomes of relapsed RMS patients in France.

Methods: We retrospectively reviewed all nonmetastatic RMS patients enrolled in France in the RMS 2005 study who relapsed between 2006 and 2019 after achieving complete local control, defined as complete remission or stable residue ≥ 6 months after treatment completion.

Objective: To assess the incidence of posthepatectomy liver failure (PHLF) and the role of the future liver remnant (FLR) in children undergoing major hepatectomy.

Summary Background Data: Incidence and risk factors of PHLF in children are unclear, with no validated definition for this age group. Consequently, the role of the FLR in pediatric hepatectomy and evidence-based preoperative guidelines remain undefined.

Background/objectives: In paediatric liver transplantation, donor-recipient compatibility depends on graft size. We explored whether the graft weight can be predicted using the donor's biometric parameters.

Methods: We used seven easily available biometric variables in 142 anonymised paediatric and adult donors, with data collected between 2016 and 2022.
