To determine the characteristics and outcomes of patients pronepositioned during extracorporeal membrane oxygenation for severe acute respiratory distress syndrome and lung CT pattern associated with improved respiratory system static compliance after that intervention. DESIGN:Retrospective, single-center study over 8 years. SETTINGS:Twenty-six bed ICU in a tertiary center. MEASUREMENTS AND MAIN RESULTS:A propensity score-matched analysis compared patients with prone-positioning during extracorporeal membrane oxygenation and those without. An increase of the static compliance greater than or equal to 3 mL/cm H 2 O after 16 hours of prone-positioning defined pronepositioning responders. The primary outcome was the time to successful extracorporeal membrane oxygenation weaning within 90 days of postextracorporeal membrane oxygenation start, with death as a competing risk. Among 298 venovenous extracorporeal membrane oxygenation-treated adults with severe acute respiratory distress syndrome, 64 were prone-positioning extracorporeal membrane oxygenation. Although both propensity score-matched groups had similar extracorporeal membrane oxygenation durations, prone-positioning extracorporeal membrane oxygenation patients' 90-day probability of being weaned-off extracorporeal membrane oxygenation and alive was higher (0.75 vs 0.54, p = 0.03; subdistribution hazard ratio [95% CI], 1.54 [1.05-2.58]) and 90-day mortality was lower (20% vs 42%, p < 0.01) than that for no prone-positioning extracorporeal membrane oxygenation patients. Extracorporeal membrane oxygenation-related complications were comparable for the two groups. Patients without improved static compliance had higher percentages of nonaerated or poorly aerated ventral and medial-ventral lung regions (p = 0.047). CONCLUSIONS:Prone-positioning during venovenous extracorporeal membrane oxygenation was safe and effective and was associated with a higher probability of surviving and being weaned-off extracorporeal membrane oxygenation at 90 days. Patients with greater normally aerated lung tissue in the ventral and medial-ventral regions on quantitative lung CT-scan performed before prone-positioning are more likely to improve their static compliance after that procedure during extracorporeal membrane oxygenation.

The primary objective of the study was to assess the prevalence of burnout among paediatric residents during the coronavirus disease 2019 (COVID-19) outbreak in France. The secondary objective was to identify risk factors associated with burnout in this population. In a nationwide, cross-sectional survey, a questionnaire was e-mailed to all paediatric residents in France in the first week of May 2020. The prevalence of burnout was assessed with the validated French-language version of the Maslach Burnout Inventory -Human Services Survey. The questionnaire also contained items on the residents' sociodemographic characteristics and professional situation. Three hundred and forty paediatric residents completed the questionnaire. The median age was 27 (interquartile range 25-28) and 285 (83.8%, 95% confidence interval (CI) [79.5-87.6]) of the residents were women. The prevalence of burnout was 37.4%, ]. There was no association between burnout and exposure to the consequences of COVID-19, which may be related to the low incidence of severe COVID-19 among children. In contrast, the hours worked per week and the anxiety scores were significantly associated with burnout. Conclusion:The level of burnout among French paediatric residents is a matter of concern for residents, and cannot be ascribed to the COVID-19 outbreak. Preventive actions should be implemented, with a reduction in working hours and support programs to help manage work-related anxiety.

We explored the relevance of a Clustered regularly interspaced short palindromic repeats (CRISPR)-based genotyping tool for Streptococcus agalactiae typing and we compared this method to current molecular methods [multi locus sequence typing (MLST) and capsular typing]. To this effect, we developed two CRISPR marker schemes (using 94 or 25 markers, respectively). Among the 255 S. agalactiae isolates tested, 229 CRISPR profiles were obtained. The 94 and 25 markers made it possible to efficiently separate isolates with a high diversity index (0.9947 and 0.9267, respectively), highlighting a high discriminatory power, superior to that of both capsular typing and MLST (diversity index of 0.9017 for MLST). This method has the advantage of being correlated with MLST [through analysis of the terminal direct repeat (TDR) and ancestral spacers] and to possess a high discriminatory power (through analysis of the leader-end spacers recently acquired, which are the witnesses of genetic mobile elements encountered by the bacteria). Furthermore, this “one-shot” approach presents the benefit of much-reduced time and cost in comparison with MLST. On the basis of these data, we propose that this method could become a reference method for group B Streptococcus (GBS) typing.
