RESUMO
BACKGROUND: In burn patients, skin barrier disruption and immune dysfunctions increase susceptibility to invasive fungal diseases (IFDs) like invasive candidiasis (IC) and invasive mold infections (IMI). We provide an in-depth analysis of IFD-related factors and outcomes in a 10-year cohort of severe burn patients. METHOD: Retrospective cohort study including adult patients admitted to the Burn Intensive Care Unit (BICU) between April 2014 and May 2023 with Total Burn Surface Area (TBSA) ≥15%. Patients were classified as proven IFD according to EORTC/MSGERC criteria applicable for IC. Putative IMIs were defined with: ≥2 positive cultures from a skin biopsy/bronchoalveolar lavage OR ≥2 positive blood specific-qPCRs OR a combination of both. RESULTS: Among 1381 patients admitted, 276 consecutive patients with TBSA ≥15% were included. Eighty-seven (31.5%; IC n=30; IMI n=43; both n=14) patients fulfilled the criteria for probable/putative IFD. At Day 30 after the burn injury, the estimated cumulative incidence pr/pu IFD was 26.4% (95%CI 21.4-31.8%). Factors independently associated with IFDs were TBSA, severity scores and indoor burn injury (i.e., from confined space fire). Overall mortality was 15.3% and 36.8% in the no IFD, pr/pu IFD groups respectively (p<0.0001). IFD was independently associated with a risk of death (HR: 1.94 for pr/pu IFD; 95%CI, 1.12-3.36; p=0.019). DISCUSSION: This study describes 21st-century characteristics of IFDs in sever burn patients confirming known risk factors with thresholds and identifying the indoor injury as an independent factor associated to IFDs. This suggests a link to contamination caused by fire damage, which is highly susceptible to aerosolizing spores.
RESUMO
INTRODUCTION: Delayed graft function (DGF) is a frequent complication following kidney transplant. This study aimed to assess the association between early post-operative lactate variation and DGF. METHODS: This was a single center, retrospective cohort study between February 2021 and December 2022 in Saint-Louis Hospital (APHP, France). Venous lactate levels were measured immediately (H0) and 4 h (H4) after kidney transplant. The primary outcome was the occurrence of DGF (need for renal replacement therapy between transplantation and day 7). Secondary outcome was the occurrence of complications (i.e., death, vascular thrombosis, hemorrhagic shock, urological complications (hematoma, urinoma), local or systemic infection) between transplant and day 7. RESULTS: Two hundred 12 patients were included, and 38 (17.9%) developed DGF. Venous lactate variation between H0 and H4 was higher in patients who developed DGF (-30 (IQR -83, -6)% vs. -15 (IQR -62, -11)%, p = .037), but the variation of level was more often positive (corresponding to an increased lactate production over time between H0 and H4) in patients who developed DGF ((28(85%) vs. 94(62%), p = .011). In multivariate logistic regression, positive venous lactate level variation between H0 and H4 was strongly associated with a reduced risk of developing DGF (OR .30 [.09-.79], p = .024). We did not find any association between post-operative hyperlactatemia and occurrence of complications between transplant and day 7. DISCUSSION: DGF is a frequent complication following kidney transplantation. Its early prediction could help physicians optimize treatment and protect the kidney. Early venous lactate variation after kidney transplant could help to predict the occurrence of DGF.

We present our findings on interpatient transmission, epidemic control measures, and the outcomes of a series of ten critically ill burn patients who were either colonized or infected with carbapenem-resistant Acinetobacter baumannii (CRAB). None of the five infected patients achieved clinical cure, and all experienced relapses. Microbiological failure was observed in 40% of the infected patients. The isolated CRAB strains were found to carry blaOXA-23 and armA resistance genes. Despite the lack of clinical cure, all five infected patients survived and were discharged from the Burn Intensive Care Unit.

PURPOSE: The present study aimed at assessing the prevalences of post-traumatic stress disorder (PTSD) (main objective), anxiety, depression, and burnout syndrome (BOS) and their associated factors in intensive care unit (ICU) staff workers in the second year of the COVID-19 pandemic. MATERIALS AND METHODS: An international cross-sectional multicenter ICU-based online survey was carried out among the ICU staff workers in 20 ICUs across 3 continents. ICUs staff workers (both caregivers and non-caregivers) were invited to complete PCL-5, HADS, and MBI questionnaires for assessing PTSD, anxiety, depression, and the different components of BOS, respectively. A personal questionnaire was used to isolate independent associated factors with these disorders. RESULTS: PCL-5, HADS, and MBI questionnaires were completed by 585, 570, and 539 responders, respectively (525 completed all questionnaires). PTSD was diagnosed in 98/585 responders (16.8%). Changing familial environment, being a non-caregiver staff worker, having not being involved in a COVID-19 patient admission, having not been provided with COVID-19-related information were associated with PTSD. Anxiety was reported in 130/570 responders (22.8%). Working in a public hospital, being a woman, being financially impacted, being a non-clinical healthcare staff member, having no theoretical or practical training on individual preventive measures, and fear of managing COVID-19 patients were associated with anxiety. Depression was reported in 50/570 responders (8.8%). Comorbidity at risk of severe COVID-19, working in a public hospital, looking after a child, being a non-caregiver staff member, having no information, and a request for moving from the unit were associated with depression. Having received no information and no adequate training for COVID-19 patient management were associated with all 3 dimensions of BOS. CONCLUSION: The present study confirmed that ICU staff workers, whether they treated COVID-19 patients or not, have a substantial prevalence of psychological disorders.
RESUMO
BACKGROUND: Drug challenge is the gold standard for identifying causative agents of drug allergies. Although clinical guidelines have recently been published, they do not recommend neuromuscular blocking agent (NMBA) drug challenges. NMBA challenges are rendered difficult by the lack of homogeneity of routine allergy work-ups and the necessity of a specialised setting. Several scenarios support NMBA challenges, such as an ambiguous allergy work-up, a high suspicion of a false-positive skin test or identification of a well tolerated alternative NMBA strategy. Furthermore, routine allergy work-ups may not recognise non-IgE mechanisms, such as IgG or MRGPRX2, whereas drug challenges may reveal them. Finally, if the culprit NMBA is not identified, subsequent anaesthesia regimens will be challenging to implement, resulting in increased risk. OBJECTIVES: This literature review discusses the indications, strategies, doses, monitoring methods, limitations, and unresolved issues related to drug challenges for NMBAs. DESIGN: The literature review included randomised controlled trials, observational studies, reviews, case reports, series, and comments on humans. DATA SOURCES: Studies were retrieved from databases (PubMed) and electronic libraries (OVID, EMBASE, Scopus, etc.). ELIGIBILITY CRITERIA: All studies that referred to the NMBA challenge were included without publication date limitations. RESULTS: NMBA challenge may be considered in NMBA anaphylaxis patients with inconclusive or ambivalent IgE diagnostic work-up under controlled conditions (presence of anaesthetists and allergists with continuous monitoring in a secured environment). To illustrate its utility, a case report of a double NMBA challenge in a patient with NMBA cross-reactivity is presented, along with biological explorations to detect subclinical cellular activation, a novel aspect of this procedure. CONCLUSION: Drug challenges could be implemented during the NMBA allergy work-up under strict safety conditions at specialised centres with close collaboration between anaesthetists and allergists. This could decrease uncertainty and contribute to defining a safer strategy for subsequent anaesthetic drug regimens.
RESUMO
Phenomenon: The urgency of having fair and trustworthy competency-based assessment in medical training is growing. Simulation is increasingly recognized as a potent method for building and assessing applied competencies. The growing use of simulation and its application in summative assessment calls for comprehensive and rigorously designed programs. Defining the current baseline of what is available and feasible is a crucial first step. This paper uses anesthesia and intensive care (AIC) in France as a case study in how to document this baseline. Approach: An IRB-approved, online anonymous closed survey was submitted to AIC residency program directors and AIC simulation program directors in France from January to February 2021. The researcher-developed survey consisted of 65 questions across five sections: centers' characteristics, curricular characteristics, courses' characteristics, instructors' characteristics, and simulation perceptions and perspectives. Findings: The participation rate was 31/31 (100%) with 29 centers affiliated with a university hospital. All centers had AIC simulation activities. Resident training was structured in 94% of centers. Simulation uses were training (100%), research and development (61%), procedural or organizational testing (42%), and summative assessment (13%). Interprofessional full-scale simulation training existed in 90% of centers. Procedural training on simulators prior to clinical patients' care was performed "always" in 16%, "most often" in 45%, "sometimes" in 29% and "rarely" or "not" in 10% of centers. Simulated patients were used in 61% of centers. Main themes were identified for procedural skills, full-scale and simulated patient simulation training. Simulation activity was perceived as increasing in 68% of centers. Centers expressed a desire to participate in developing and using a national common AIC simulation program. Insights: Based on our findings in AIC, we demonstrated a baseline description of nationwide simulation activities. We now have a clearer perspective on a decentralized approach in which individual institutions or regional consortia conduct simulation for a discipline in a relatively homogeneous way, suggesting the feasibility for national guidelines. This approach provides useful clues for AIC and other disciplines to develop a comprehensive and meaningful program matching existing expectations and closing the identified gaps.

Diagnosis of coronavirus disease 2019 (COVID-19)-associated pulmonary aspergillosis (CAPA) remains unclear especially in nonimmunocompromised patients. The aim of this study was to evaluate seven mycological criteria and their combination in a large homogenous cohort of patients. All successive patients (n = 176) hospitalized for COVID-19 requiring mechanical ventilation and who clinically worsened despite appropriate standard of care were included over a 1-year period. Direct examination, culture, Aspergillus quantitative PCR (Af-qPCR), and galactomannan testing were performed on all respiratory samples (n = 350). Serum galactomannan, ß-d-glucan, and plasma Af-qPCR were also assessed. The criteria were analyzed alone or in combination in relation to mortality rate. Mortality was significantly different in patients with 0, ≤2, and ≥3 positive criteria (log rank test, P = 0.04) with death rate of 43.1, 58.1, and 76.4%, respectively. Direct examination, plasma qPCR, and serum galactomannan were associated with a 100% mortality rate. Bronchoalveolar lavage (BAL) galactomannan and positive respiratory sample culture were often found as isolated markers (28.1 and 34.1%) and poorly repeatable when a second sample was obtained. Aspergillus DNA was detected in 13.1% of samples (46 of 350) with significantly lower quantitative cycle (Cq) when associated with at least one other criterion (30.2 versus 35.8) (P < 0.001). A combination of markers and/or blood biomarkers and/or direct respiratory sample examination seems more likely to identify patients with CAPA. Af-qPCR may help identifying false-positive results of BAL galactomannan testing and culture on respiratory samples while quantifying fungal burden accurately.

PURPOSE OF REVIEW: The purpose of this review is to discuss the optimal use of neuromuscular blocking agents (NMBA) during ambulatory surgery, and to provide an update on the routine use of neuromuscular monitoring and the prevention of residual paralysis. RECENT FINDINGS: The number of major surgical procedures performed in ambulatory patients is likely to increase in the coming years, following the development of laparoscopic and thoracoscopic procedures. To successfully complete these procedures, the proper use of NMBA is mandatory. The use of NMBA not only improves intubating conditions but also ventilation. Recent studies demonstrate that NMBA are much more the solution rather than the cause of airway problems. There is growing evidence that the paralysis of the diaphragm and the abdominal wall muscles, which are resistant to NMBA is of importance during laparoscopic surgery. Further studies are still required to determine when deep neuromuscular block [posttetanic count (PTC) < 5] is required perioperatively. There is now a consensus to use perioperatively neuromuscular monitoring and particularly objective neuromuscular monitoring in combination with reversal agents to avoid residual paralysis and its related morbidity (e.g. respiratory complications in the PACU). SUMMARY: Recent data suggest that it is now possible to obtain a tight control of neuromuscular block to maintain optimal relaxation tailored to the surgical requirements and to obtain a rapid and reliable recovery at the end of the procedure.

BACKGROUND: Our aim was to assess the occurrence of secondary insults (SIs) or adverse events (AEs) during intrahospital transport (IHT) of severe traumatic brain injury (TBI) patients for head computed tomography (CT) scanning. METHODS: A prospective study based on severe TBI patients admitted from June 2011 through June 2013 in a level I trauma center. Patients received an IHT to perform a control CT scan in the first 3 days following trauma. The occurrence of SIs and AEs was assessed during the IHT for a control CT scan. The frequency of SIs was compared to the periods "before," "during," and "after" IHT. SI was defined by an intracranial pressure (ICP) >30 mmHg, a cerebral perfusion pressure (CPP) <50 mmHg, systolic blood pressure (SBP) <90 mmHg, or saturation pulse O2 (SpO2) <90 % for more than five consecutive minutes. An AE was defined as failures of hardware or ventilator asynchrony requiring therapeutic intervention during transport. In addition, we assessed the therapeutic benefit of a CT scan control. RESULTS: The final analysis included 31 patients and 31 IHTs. The median duration of IHT was 29 min [25;37]. SIs occurred in 16 patients (52 %) during transport, whereas it was observed in 4 patients (13 %) before (p = 0.002) and 4 patients (13 %) after IHT (p = 0.001). Twenty-four AEs occurred during transport of 19 patients (61 %). One patient benefited from hematoma evacuation after implementation of control CT. CONCLUSION: IHT carries significant SIs and AEs in severe TBI patients. To improve a risk/benefit ratio favorable for patients, a program focusing on IHT complications regarding therapeutic impact of control CT scan is needed.

BACKGROUND: Microglial cells are tissue-resident macrophages of the central nervous system. They are extremely dynamic, sensitive to their microenvironment and present a characteristic complex and heterogeneous morphology and distribution within the brain tissue. Many experimental clues highlight a strong link between their morphology and their function in response to aggression. However, due to their complex "dendritic-like" aspect that constitutes the major pool of murine microglial cells and their dense network, precise and powerful morphological studies are not easy to realize and complicate correlation with molecular or clinical parameters. METHODS: Using the knock-in mouse model CX3CR1(GFP/+), we developed a 3D automated confocal tissue imaging system coupled with morphological modelling of many thousands of microglial cells revealing precise and quantitative assessment of major cell features: cell density, cell body area, cytoplasm area and number of primary, secondary and tertiary processes. We determined two morphological criteria that are the complexity index (CI) and the covered environment area (CEA) allowing an innovative approach lying in (i) an accurate and objective study of morphological changes in healthy or pathological condition, (ii) an in situ mapping of the microglial distribution in different neuroanatomical regions and (iii) a study of the clustering of numerous cells, allowing us to discriminate different sub-populations. RESULTS: Our results on more than 20,000 cells by condition confirm at baseline a regional heterogeneity of the microglial distribution and phenotype that persists after induction of neuroinflammation by systemic injection of lipopolysaccharide (LPS). Using clustering analysis, we highlight that, at resting state, microglial cells are distributed in four microglial sub-populations defined by their CI and CEA with a regional pattern and a specific behaviour after challenge. CONCLUSIONS: Our results counteract the classical view of a homogenous regional resting state of the microglial cells within the brain. Microglial cells are distributed in different defined sub-populations that present specific behaviour after pathological challenge, allowing postulating for a cellular and functional specialization. Moreover, this new experimental approach will provide a support not only to neuropathological diagnosis but also to study microglial function in various disease models while reducing the number of animals needed to approach the international ethical statements.

Terminal Schwann cells (TSCs) are key components of the mammalian neuromuscular junction (NMJ). How the TSCs sense the synaptic activity in physiological conditions remains unclear. We have taken advantage of the distinct localization of acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) at the NMJ to bring out the function of different ACh receptors (AChRs). AChE is clustered by the collagen Q in the synaptic cleft and prevents the repetitive activation of muscle nicotinic AChRs. We found that BChE is anchored at the TSC by a proline-rich membrane anchor, the small transmembrane protein anchor of brain AChE. When BChE was specifically inhibited, ACh release was significant depressed through the activation of α7 nAChRs localized on the TSC and activated by the spillover of ACh. When both AChE and BChE were inhibited, the spillover increased and induced a dramatic reduction of ACh release that compromised the muscle twitch triggered by the nerve stimulation. α7 nAChRs at the TSC may act as a sensor for spillover of ACh adjusted by BChE and may represent an extrasynaptic sensor for homeostasis at the NMJ. In myasthenic rats, selective inhibition of AChE is more effective in rescuing muscle function than the simultaneous inhibition of AChE and BChE because the concomitant inhibition of BChE counteracts the positive action of AChE inhibition. These results show that inhibition of BChE should be avoided during the treatment of myasthenia and the pharmacological reversal of residual curarization after anesthesia.

BACKGROUND: Our aim was to describe the pattern of ventriculostomy-related infection (VRI) development using a dynamic approach. STUDY DESIGN: Retrospective longitudinal study. METHODS: We analyzed the files of 449 neurosurgical patients who underwent placement of external ventricular drain (EVD). During the study period, CSF sampling was performed on a daily base setting. VRI was defined as a positive CSF culture resulting in antibiotic treatment. For VRI patients, we arbitrary defined day 0 (D0) as the day antibiotic treatment was started. In these patients, we compared dynamic changes in clinical and biological parameters at four pre-determined time points: (D-4, D-3, D-2, D-1) with those of D0. For all CSF-positive cultures, we compared CSF biochemical markers' evolution pattern between VRI patients and the others, considered as a control cohort. RESULTS: Thirty-two suffered from VRI. Peripheral white blood cell count did not differ between D-4-D0. Median body temperature, CSF cell count, median Glasgow Coma Scale, CSF protein, and glucose concentrations were significantly different between D-4, D-3, D-2, and D0. At D0, 100 % of CSF samples yielded organisms in culture. The physician caring for the patient decided to treat VRI based upon positive CSF culture in only 28 % (9/32) of cases. In the control cohort, CSF markers' profile trends to normalize, while it worsens in the VRI patients. CONCLUSIONS: We showed that clinical symptoms and biological abnormalities of VRI evolved over time. Our data suggest that VRI decision to treat relies upon a bundle of evidence, including dynamic changes in CSF laboratory exams combined with microbiological analysis.

BACKGROUND: In emergency situations requiring rapid airway control, shortening preoxygenate time is desirable. OBJECTIVES: The objective of this study is to compare the time to achieve an expired O2 fraction FeO2 of 90% (FeO2 90%) during preoxygenation with spontaneous breathing and positive pressure ventilation with and without positive end-expiratory pressure (PEEP). DESIGN: A randomised controlled trial. SETTING: Primary care in a university hospital in France from October 2006 to January 2008. PATIENTS: Adults patients scheduled for elective surgery. Exclusion criteria were rapid sequence induction, anticipated difficult airway management and refusal to provide consent. INTERVENTION: Patients were randomly allocated to preoxygenation with spontaneous breathing or positive pressure ventilation (positive inspiratory pressure: 12 cmH2O) without PEEP and with PEEP (positive inspiratory pressure: 12 cmH2O, PEEP: 6 cmH2O). MAIN OUTCOME MEASURES: Time to achieve an expired O2 fraction of 90% measured from positioning the face mask, and the time it took after endotracheal intubation for the SpO2 to fall to 93% (SpO2 93%) while the patient was apnoeic. Patient discomfort was recorded (visual analogue scale). Data are median (quartile 25th to 75). RESULTS: The time to achieve an FeO2 90% was shorter with positive pressure ventilation, with PEEP [140 (100 to 200) s] and without PEEP [153 (120 to 218) s], than with spontaneous breathing [190 (130 to 264) s; P = 0.002]. At 3 in, 47, 60 and 74% of patients achieved an FeO2 of 90% or more in the spontaneous breathing, positive pressure ventilation without and with PEEP groups, respectively (P = 0.01). Cox proportional-hazards regression showed that positive pressure ventilation with PEEP [hazard ratio 2.18; 95% confidence interval (95% CI) 1.42 to 3.36); P < 0.001] and without PEEP (hazard ratio 1.62; 95% CI 1.05 to 2.50; P = 0.03) were associated with a shorter time to an FeO2 90%. The time until SpO2 93% was not significantly different between spontaneous breathing [305 (263 to 383) s], positive pressure ventilation without PEEP [370 (300 to 450) s] and with PEEP [345 (245 to 435) s; P = 0.08]. The discomfort reported was 0 (0 to 18) mm and was comparable between groups (P = 0.22). CONCLUSION: Compared with spontaneous breathing, positive pressure ventilation with and without PEEP shortened preoxygenation time. TRIAL REGISTRATION: Clinicaltrials.gov identifier: NCT02313766.

PURPOSE: Caustic ingestion is a potential life-threatening condition associated with high morbidity and mortality. Data on patients admitted to Intensive Care Unit (ICU) for severe caustic ingestion are lacking. We aimed to describing epidemiological features and outcomes of patients admitted to ICU for caustic ingestion in France. METHODS: In a retrospective, observational, and multicenter study, data from the national French Programme de Médicalisation des Systèmes d'Informations (PMSI) database were analysed from 2013 to 2019. In-hospital mortality rate (primary outcome) and in-ICU complications (secondary outcomes) were reported and analysed. RESULTS: 569 patients (289 males (50.8%), with median age of 49 years [interquartile (26-62)] were admitted in 65 French ICU for severe caustic ingestion. Five hundred and thirteen patients (90%) were admitted for intentional caustic ingestion. The median length of stay in ICU was 14.0 [4.0-31.0] days. In-hospital mortality occurred in 56 patients (9.8%). In multivariate analysis, age and simplified acute physiology score II were associated with in-hospital mortality age of 40-59 years [OR = 15.3 (2.0-115.3)], age of 60-79 years [OR = 23.6 (3.1-182.5)], and age > 80 years [OR = 37.0 (4.2-328.6)] and SAPS 2 score [OR = 1.0018 (1.003-1.033), p < 0.001]. During ICU stay, 423 complications (74%) were reported in 505 patients (89%). Infectious (244 (42.9%)), respiratory (207 (36.4%)), surgical 62 (10.9%), haemorrhagic (64 (11.2%)) and thrombo-embolic and (35 (6.2%)) complications were the most frequently reported during ICU stay. CONCLUSION: ICU admission for severe caustic ingestion is associated with 9.8% mortality and 74% complications. Age > 40 years and SAPS 2 score were independently associated with mortality.

Introduction: Dipeptidyl peptidase-3 (DPP3) is a protease involved in the degradation of several cardiovascular mediators. Adrenomedullin (bio-ADM) is a peptide essential for regulation of endothelial barrier function. In different shock-pathologies, both biomarkers are associated with disease severity, organ dysfunction and mortality. Associations with outcome in critically ill COVID-19 patients are unknown. The objectives of the present study were to investigate associations of bio-ADM and "circulating DPP3" (cDPP3) with short-term outcome in critically ill COVID-19 patients (n=80). Methods: A multicentre prospective cohort study was performed. The primary end-point was 28-day mortality. Secondary end-points included different severities of acute kidney injury (AKI). Results: cDPP3 levels were mainly associated with 28-day mortality; Area under the receiver operating characteristics (AUROCs) of 0.69 (0.56-0.82, p=0.023), 0.77 (0.64-0.90, p<0.001) and 0.81 (0.65-0.96, p<0.001) at admission, day 3 and day 7, respectively. In contrast, bio-ADM levels were mainly associated with AKI, with AUROCs of 0.64 (0.51-0.77, p=0.048), 0.75 (0.64-0.86, p<0.001) and 0.83 (0.74-0.93, p<0.001) for day 1, 3 and 7, respectively. Interestingly, patients with high levels of both cDPP3 and bio-ADM at day 7 had an additionally increased risk of 28-day mortality (hazard ratio 11.8; 95% CI 2.5-55.3, p<0.001). Conclusions: cDPP3 and bio-ADM responses were associated with short-term mortality and AKI in critically ill COVID-19 patients, respectively. These findings suggest that treatment with specific antibodies modulating cDPP3 or bio-ADM-related pathways may improve outcome of COVID-19.
