Filter by:In this biological study, we will evaluate the levels of breast milk IgA, neonatal fecal IgA, and the composition of breast milk and fecal microbiota throughout the first 12 months of life in neonates born to mothers treated or not treated with prenatal antibiotics for at least 7 days after the 32nd weeks of gestation
Anesthesia and surgical guidelines recommend the administration of a surgical antibiotic prophylaxis for patients undergoing "clean" surgery. The prescribed antibiotic should target the bacteria most commonly found in surgical site infections (SSIs) and the duration of administration should not exceed 24 hours to minimize the ecological risk of bacterial resistance emergence. Guidelines provide a framework for the administration of surgical antibiotic prophylaxis but their effectiveness is regularly re-evaluated by measuring the rates of SSIs and the microorganisms responsible for infectious complications after surgery. The majority of interventions required the use of first or second generation cephalosporins as surgical antibiotic prophylaxis. For patients with allergy to beta-lactams, clindamycin and vancomycin are proposed as alternatives. In the patients with methicillin-resistant S. aureus (MRSA) colonization or if those at risk of developing MRSA-associated SSI (hospital ecology, previous antibiotic treatment), only vancomycin is recommended. Vancomycin pharmacokinetics and pharmacodynamics is complex and its tissue absorption varies according to the level of tissue inflammation. This is a difficult molecule to handle, exclusively administered via intravenous route. Linezolid is a synthetic antibiotic from the oxazolidinone class. By binding to the rRNA on the 30S and 50S ribosomal subunits, it inhibits the bacterial synthesis. It is therefore a bacteriostatic antibiotic approved for the treatment of both methicillin susceptible S. aureus (MSSA) and MRSA infections. It also covers a broad spectrum of Gram positive bacteria. Its pharmacokinetics allows rapid intravenous infusion, with rapid penetration into bone and soft tissue of the surgical site during hip surgery. A large Cochrane meta-analysis reported that linezolid was superior to vancomycin in skin infections, including MRSA infections, albeit with low quality evidence. We therefore hypothesized that linezolid can be used instead of vancomycin for beta-lactam allergic patients and patients at risk of MRSA-associated SSI in general surgery.
The current practice of pre-VCUG antibiotic prophylaxis is highly variable. A recent unpublished survey of Society of Fetal Urologists (SFU) completed by this study team found that 87% of respondents reported having patients who develop fUTI following VCUG, with 30% of respondents prophylaxing for fUTI in patients undergoing VCUG. The current lack of best practice guidelines regarding antibiotic prophylaxis prior to VCUG due to low quality of current literature, and a growing concern around risks of unnecessary antibiotic exposure suggests the need for an RCT. The results of this pilot trial will inform the ability to conduct a definitive RCT on this important subject. The results of the definitive trial would have important clinical and economic implications.
