RESUMO

BACKGROUND: Pelvic bone and/or soft tissue sarcoma removal surgeries are associated with a high rate of surgical site infection (SSI). The recommended antibiotic prophylaxis (ABP) duration is 24-48 h. We aimed to assess the impact of extended ABP (5 days) on the SSI rate and describe the microbiology of SSI in bone and/or soft tissue pelvic sarcomas. METHODS: We retrospectively included all consecutive patients who underwent pelvic bone and/or soft tissue sarcoma removal surgery between January 2010 and June 2020. RESULTS: We analyzed 146 patients with pelvic bone (45, 31%) or soft tissue (101, 69%). Sixty patients (41%) developed SSI. SSI occurred in 13/28 (46.4%) in the extended ABP group versus 47/118 (39.8%) in the standard group (p = 0.53). In multivariable analysis, risk factors for SSI were surgery duration (OR: 1.94 [1.41-2.92] per h), stay in postoperative ICU for more than 2 days (12.0 [2.8-61.3]), and shred or autologous skin flap (39.3 [5.8-409.5]). Extended ABP was not associated with SSI. SSI were mainly polymicrobial with Enterobacterales (57.4%) and Enterococcus (45%). CONCLUSIONS AND DISCUSSION: Pelvic bone and/or soft tissue sarcoma removal surgery is highly prone to postoperative infection. Extending the ABP to 5 days does not reduce the level of SSI.

RESUMO

OBJECTIVES: This study aimed at characterizing the pharmacokinetics (PK) of oral levofloxacin in adult patients in order to optimize dosing scheme and explore the PK/pharmacodynamics (PD) of levofloxacin in bone and joint infections (BJIs). METHODS: From November 2015 to December 2019, all patients hospitalized in Cochin Hospital, treated with levofloxacin and who had at least one dosage for therapeutic drug monitoring were included. PK was described using non-linear mixed-effect modelling. In a subgroup of patients with BJIs, the association between PK, MIC for the isolated pathogen and clinical outcome was investigated. Monte Carlo simulations investigated dosing regimens to achieve the PK/PD target (AUC/MIC ratio >100). RESULTS: One hundred and two patients were included (199 measurements), including 32 treated for BJI. A one-compartment model with first-order absorption and elimination best described the data. Effects of estimated creatinine clearance (eCLCR) and age were significant on levofloxacin clearance. In BJI patients, no significant association was found between levofloxacin PK/microbiological parameters and either clinical outcome or adverse events. Based on our model, we proposed optimized oral levofloxacin dosing regimens according to renal function, to reach the PK/PD target AUC/MIC ratio >100 for three frequent causative pathogens (Staphylococcus aureus, Enterobacterales and Pseudomonas aeruginosa). CONCLUSIONS: Our results reinforce the need of determining the MIC and using therapeutic drug monitoring in complex infections caused by P. aeruginosa.

RESUMO

BACKGROUND: Aminoglycosides have a concentration-dependent therapeutic effect when peak serum concentration (Cmax) reaches eight to tenfold the minimal inhibitory concentration (MIC). With an amikacin MIC of 8 mg/L, the Cmax should be 64-80 mg/L. This objective is based on clinical breakpoints and not on measured MIC. This study aimed to assess the proportion of patients achieving the pharmacokinetic/pharmacodynamic (PK/PD) target Cmax/MIC ≥ 8 using the measured MIC in critically ill patients treated for documented Gram-negative bacilli (GNB) infections. METHODS: Retrospective analysis from February 2016 to December 2017 of a prospective database conducted in 2 intensive care units (ICU). All patients with documented severe GNB infections treated with amikacin (single daily dose of 25 mg/kg of total body weight (TBW)) with both MIC and Cmax measurements at first day of treatment (D1) were included. Results are expressed in n (%) or median [min-max]. RESULTS: 93 patients with 98 GNB-documented infections were included. The median Cmax was 55.2 mg/L [12.2-165.7] and the median MIC was 2 mg/L [0.19-16]. Cmax/MIC ratio ≥ 8 was achieved in 87 patients (88.8%) while a Cmax ≥ 64 mg/L was achieved in only 38 patients (38.7%). Overall probability of PK/PD target attainment was 93%. No correlation was found between Cmax/MIC ratio and clinical outcome at D8 and D28. CONCLUSION: According to PK/PD parameters observed in our study, single daily dose of amikacin 25 mg/kg of TBW appears to be sufficient in most critically ill patients treated for severe GNB infections.

RESUMO

BACKGROUND: Noise, which is omnipresent in operating rooms and ICUs, may have a negative impact not only patients but also on the concentration of and communication between clinical staff. OBJECTIVE: The present study attempted to evaluate the impact of noise on the performance of anaesthesiology residents' clinical reasoning. Changes in clinical reasoning were measured by script concordance tests (SCTs). DESIGN: This was a randomised and crossover study. SETTING: Single centre at Rouen University Hospital in April 2014. POPULATION: All year 1 to 4 residents enrolled in the anaesthesiology training programme were included. INTERVENTION: Performance was assessed using a 56-item SCT. Two resident groups were formed, and each was exposed to both quiet and noisy atmospheres during SCT assessment. Group A did the first part of the assessment (28 SCT) in a quiet atmosphere and the second part (28 SCT) in a noisy atmosphere. Group B did the same in reverse order. MAIN OUTCOME MEASURES: The primary outcome of this study was residents' performance as measured by SCT, with and without noise (mean of 100 points 95% confidence interval). RESULTS: Forty-two residents were included. Residents' performance, measured by SCT, was weaker in a noisy environment than in a quiet environment [59.0 (56.0 to 62.0) vs 62.8 (60.8 to 64.9), P = 0.04]. This difference lessened as medical training advanced, as this difference in performance in noisy vs quiet environments was not observed in year 3 and 4 residents [62.9 (59.2 to 66.5) vs 64.0 (61.9 to 66.1), P = 0.60], whereas it was higher for year 1 and 2 residents [54.8 (50.6 to 59.1) vs 61.5 (57.9 to 65.1), P = 0.02]. CONCLUSION: Our study suggests that noise affects clinical reasoning of anaesthesiology residents especially junior residents when measured by SCT. This observation supports the hypothesis that noise should be prevented in operating rooms especially when junior residents are providing care.

RESUMO

In a French randomized trial, children at school-age demonstrated no evidence of harm from fetal exposure to MgSO4 before very preterm birth. Motor dysfunction/death, qualitative behavioral disorders, cognitive difficulties, school grade repetition, and education services were decreased in the children exposed to MgSO4, although the differences were not significant.
