Association of severe postpartum hemorrhage and development of psychological disorders: Results from the prospective and multicentre HELP MOM study.

OBJECTIVE: Post-partum hemorrhage (PPH) is the leading preventable cause of worldwide maternal morbidity and mortality. Risk factors for psychological disorders following PPH are currently unknown. HELP-MOM study aimed to determine the incidence and identify risk factors for psychological disorders following PPH. METHODS: HELP-MOM study was a prospective, observational, national, and multicentre study including patients who experienced severe PPH requiring sulprostone. The primary endpoint was the occurrence of psychological disorders (anxiety and/or post-traumatic disorder and/or depression) following PPH, assessed at 1, 3, and 6 months after delivery using HADS, IES-R, and EPDS scales. RESULTS: Between November 2014 and November 2016, 332 patients experienced a severe PPH and 236 (72%) answered self-questionnaires at 1, 3, and 6 months. A total of 161 (68%) patients declared a psychological disorder following severe PPH (146 (90.1%) were screened positive for anxiety, 96 (58.9%) were screened positive for post-traumatic stress disorder, and 94 (57.7%) were screened positive for post-partum depression). In multivariable analysis, the use of intra-uterine tamponnement balloon was associated with a lower risk to be screened positive for psychological disorder after severe PPH (OR = 0.33 [IC95% 0.15-0.69], p = 0.004, and after propensity score matching (OR=0.34 [IC95% 0.12-0.94], p = 0.04)). Low hemoglobin values during severe PPH management were associated with a higher risk of being screened positive for psychological disorders. Finally, we did not find differences in desire or pregnancy between patients without or with psychological disorders occurring in the year after severe PPH. DISCUSSION: Severe PPH was associated with significant psychosocial morbidity including anxiety, post-traumatic disorder, and depression. This should engage a psychological follow-up. Large cohorts are urgently needed to confirm our results. REGISTRATION: ClinicalTrials.gov under number NCT02118038.

Evaluation of transcranial Doppler use in patients with acute liver failure listed for emergency liver transplantation.

PURPOSE: Acute liver failure (ALF) is characterized by hepatic encephalopathy (HE) often due to intracranial hypertension (ICH). The risk/benefit-balance of intraparenchymal pressure catheter monitoring is controversial during ALF. AIMS: Perform an evaluation of transcranial Doppler (TCD) use in patients with ALF listed for emergency liver transplantation. MATERIAL AND METHODS: Single center retrospective cohort study including all patients registered on high emergency LT list between 2012 and 2018. All TCD measurements performed during ICU stay after listing and after LT (when performed) were recorded. TCD was considered abnormal when pulsatility index (PI) was >1.2. RESULTS: Among 106 patients with ALF, forty-seven (44%) had a TCD while on list. They had more severe liver and extrahepatic organ failure. When performed, TCD was abnormal in 51% of patients. These patients more frequently developed ICH events (45% vs. 13%, p = .02) and more frequently required increase in sedative drugs and vasopressors. While 22% of patients with normal TCD spontaneously survived, all of those with abnormal TCD died or were transplanted (p = .02). All transplanted patients who had abnormal exams normalized their TCD within 2 (1-2) days after LT. CONCLUSION: TCD may be a useful non-invasive tool for ICH detection and management, then guide sedation withdrawal.

Multidrug-resistant Enterobacterales infections in abdominal solid organ transplantation.

BACKGROUND: Transplant recipients are highly susceptible to multidrug-resistant (MDR) related infections. The lack of early appropriate antimicrobial treatment may contribute to the high mortality due to MDR-related infections in transplant recipients especially in case of metallo-ß-lactamases. OBJECTIVES: In this review, we present the current state of knowledge concerning multidrug-resistant Gram negative bacilli's risk management in the care of solid-organ transplant recipients and suggest control strategies. SOURCES: We searched for studies treating MDR g-negative bacilli related infections in the renal and hepatic transplant patient population. We included randomized and observational studies. CONTENT: Solid-organ transplant is the best therapeutic option for patients diagnosed with end-stage organ disease. While the incidence of opportunistic infections is decreasing due to better prevention, the burden of "classical" infections related to MDR bacteria especially related to Gram-negative bacteria is constantly increasing. Over the last two decades, various MDR pathogens have emerged as a relevant cause of infection in this specific population associated with significant mortality. Several factors related to the management of transplant donor candidates and recipients increase the risk of MDR infections in transplant recipients. The awareness of this high susceptibility of transplant recipients to MDR-related infections challenges the choice of empirical therapy, while its appropriateness can only be validated a posteriori. Indeed, the lack of early appropriate antimicrobial treatment may contribute to the high mortality due to MDR-related infections in transplant recipients especially in case of metallo-ß-lactamases. IMPLICATIONS: Multidrug-resistant Gram-negative bacteria are associated with high morbidity and mortality in solid organ transplant recipients. It seems important to identify patients at risk of colonization/MDR bacteria to evaluate strategies to limit the risk of secondary infections and to minimize the inappropriate use of broad-spectrum antibiotics.

Effect of oral antimicrobial prophylaxis on surgical site infection after elective colorectal surgery: multicentre, randomised, double blind, placebo controlled trial.

OBJECTIVE: To investigate whether oral antimicrobial prophylaxis as an adjunct to intravenous antibiotic prophylaxis reduces surgical site infections after elective colorectal surgery. DESIGN: Multicentre, randomised, double blind, placebo controlled trial. SETTING: 11 university and non-university hospitals in France between 25 May 2016 and 8 August 2019. PARTICIPANTS: 926 adults scheduled for elective colorectal surgery. INTERVENTION: Patients were randomised to receive either a single 1 g dose of ornidazole (n=463) or placebo (n=463) orally 12 hours before surgery, in addition to intravenous antimicrobial prophylaxis before surgical incision. MAIN OUTCOME MEASURES: The primary outcome was the proportion of patients with surgical site infection within 30 days after surgery. Secondary outcomes included individual types of surgical site infections and major postoperative complications (Clavien-Dindo classification grade 3 or higher) within 30 days after surgery. RESULTS: Of the 960 patients who were enrolled, 926 (96%) were included in the analysis. The mean age of participants was 63 years and 554 (60%) were men. Surgical site infection within 30 days after surgery occurred in 60 of 463 patients (13%) in the oral prophylaxis group and 100 of 463 (22%) in the placebo group (absolute difference -8.6%, 95% confidence interval -13.5% to -3.8%; relative risk 0.60, 95% confidence interval 0.45 to 0.80). The proportion of patients with deep infections was 4.8% in the oral prophylaxis group and 8.0% in the placebo group (absolute difference -3.2%, 95% confidence interval -6.4% to -0.1%). The proportion of patients with organ space infections was 5.0% in the oral prophylaxis group and 8.4% in the placebo group (absolute difference -3.4%, -6.7% to -0.2%). Major postoperative complications occurred in 9.1% patients in the oral prophylaxis group and 13.6% in the placebo group (absolute difference -4.5%, -8.6% to -0.5%). CONCLUSION: Among adults undergoing elective colorectal surgery, the addition of a single 1 g dose of ornidazole compared with placebo before surgery significantly reduced surgical site infections.

Long-term outcome following blunt cerebrovascular injuries: occurrence of ischemic complications, treatment, and outcome.

PURPOSE: Blunt cerebrovascular injuries (BCVI) are a rare but serious complication after trauma. Among patients with BCVI, neurological status is altered in 30% of cases and the prognosis seems to be associated with ischemic complications. The aim of this study was to assess the long-term outcome of BCVI-associated ischemic events. METHODS: This retrospective cohort study (2011-2017) included all patients admitted for severe trauma with identified BCVI in two level-1 trauma centers. Patients were considered to have a poor neurological outcome with a GOS-E between 2 and 5 and a good neurological outcome with GOS-E between 6 and 8. A multivariate logistic regression identified risk factors for poor neurological outcome at 1 year. RESULTS: Of the 6,294 patients admitted in both trauma centers between 2011 and 2017, 81 patients presenting BCVI were identified (incidence of 1.3%). The median age was 35 years (24-44) with a median Injury Severity Score of 28 (17-41). 29 patients (50%) had a good neurological prognosis, while 25 patients (43%) had a poor neurological prognosis at 1 year. Ischemic stroke occurred in 11 patients (13.6%) within a median time of 2 days (2-2.5). No ischemic stroke occurred in the first year after ICU discharge in both groups. In our study, good prognosis at 1 year was not associated with ischemic complications [3 (10) vs 3 (12) p = 1]. CONCLUSION: Ischemic complications after BCVI are rare, occur within the first week and do not seem to impact independently the 1-year neurological prognosis.

Prognostic Impact of Early Recovering Acute Kidney Injury Following Liver Transplantation: A Multicenter Retrospective Study.

BACKGROUND: Acute kidney injury (AKI) is a common complication after liver transplantation (LT), but the specific impact of rapidly resolving AKI is not elucidated. This study investigates the factors associated with early recovery from AKI and its association with post-LT outcomes. METHODS: Retrospective analysis of 441 liver transplant recipients with end-stage liver disease without pretransplant renal impairment. AKI was defined according to Kidney Disease Improving Global Outcomes criteria and early renal recovery by its disappearance within 7 d post-LT. RESULTS: One hundred forty-six patients (32%) developed a post-LT AKI, of whom 99 (69%) recovered early and 45 (31%) did not. Factors associated with early recovery were Kidney Disease Improving Global Outcomes stage 1 (odds ratio [OR],14.11; 95% confidence interval [CI], 5.59-40.22; P < 0.0001), minimum prothrombin time >50 % (OR, 4.50; 95% CI, 1.67-13.46; P = 0.003) and aspartate aminotransferase peak value <1000 U/L (OR, 4.07; 95% CI, 1.64-10.75; P = 0.002) within 48 h post-LT. Patients with early recovery had a renal prognosis similar to that of patients without AKI with no difference in estimated glomerular filtration rate between day 7 and 1 y. Their relative risk of developing chronic kidney disease was 0.88 (95% CI, 0.55-1.41; P = 0.6) with survival identical to patients without AKI and better than patients without early recovery (P < 0.0001). CONCLUSIONS: Most patients with post-LT AKI recover early and have a similar renal prognosis and survival to those without post-LT AKI. Factors associated with early renal recovery are related to the stage of AKI, the extent of liver injury, and the early graft function. Patients at risk of not recovering may benefit the most from perioperative protective strategies, particularly those aimed at minimizing the adverse effects of calcineurin inhibitors.

ISS is not an appropriate tool to estimate overtriage.

PURPOSE: The aim of this work is to study a cohort of patients of ISS < 15 admitted to a TC, and to determine the number of patients that ultimately benefited from the skills and resources specific of a level 1 trauma center. METHODS: Retrospective study from a prospective cohort of patients admitted to TC (Beaujon Hospital, APHP) for suspected severe trauma from January 2011 to December 2017. The main outcome criterion was the use of surgery or interventional radiology within the first 24 h after admission of patients with ISS < 15. The secondary outcomes were stratified into severe (mortality, resuscitation care, length of stay in intensive care units) and non-severe criteria (mild head injury, hospital discharge or transfer within 24 h). RESULTS: Of 3035 patients admitted during the study period, 1409 with an ISS < 15 were included, corresponding to a theoretical overtriage rate of 46.4%. Among these, 611 patients (43.4%) underwent emergency intervention within the first 24 h (586 surgical interventions, 19 direct transfers to the operating theater and 6 acts of interventional radiology), 238 (16.9%) of patients presented with severe and 531 (38%) with non-severe outcome criteria. CONCLUSION: This work demonstrates that in a cohort of patients classified as ISS < 15 admitted to a TC, a considerable amount of TC-specific resources are required, and patients present with severe outcome criteria despite being classified as overtriaged. These results suggest that triage of trauma patients should be based on resource use and clinical outcome rather than anatomic criteria.

Melatonin for prevention of postoperative delirium after lower limb fracture surgery in elderly patients (DELIRLESS): study protocol for a multicentre randomised controlled trial.

INTRODUCTION: Postoperative delirium (POD) is one of the most frequent complication after surgery in elderly patients, and is associated with increased morbidity and mortality, prolonged length of stay, cognitive and functional decline leading to loss of autonomy, and important additional healthcare costs. Perioperative inflammatory stress is a key element in POD genesis. Melatonin exhibits antioxidative and immune-modulatory proprieties that are promising concerning delirium prevention, but in perioperative context literature are scarce and conflicting. We hypothesise that perioperative melatonin can reduce the incidence of POD. METHODS AND ANALYSIS: The DELIRLESS trial is a prospective, national multicentric, phase III, superiority, comparative randomised (1:1) double-blind clinical trial. Among patients aged 70 or older, hospitalised and scheduled for surgery of a severe fracture of a lower limb, 718 will be randomly allocated to receive either melatonin 4 mg per os or placebo, every night from anaesthesiologist preoperative consultation and up to 5 days after surgery. The primary outcome is POD incidence measured by either the French validated translation of the Confusion Assessment Method (CAM) score for patients hospitalised in surgery, or CAM-ICU score for patients hospitalised in ICU (Intensive Care Unit). Daily delirium assessment will take place during 10 days after surgery, or until the end of hospital stay if it is shorter. POD cumulative incidence function will be compared at day 10 between the two randomised arms in a competing risks framework, using the Fine and Grey model with death as a competing risk of delirium. ETHICS AND DISSEMINATION: The DELIRLESS trial has been approved by an independent ethics committee the Comité de Protection des Personnes (CPP) Sud-Est (ref CPP2020-18-99 2019-003210-14) for all study centres. Participant recruitment begins in December 2020. Results will be published in international peer-reviewed medical journals. TRIAL REGISTRATION NUMBER: NCT04335968, first posted 7 April 2020. PROTOCOL VERSION IDENTIFIER: N°3-0, 3 May 2021.

Development of the Gastrointestinal Dysfunction Score (GIDS) for critically ill patients - A prospective multicenter observational study (iSOFA study).

BACKGROUND & AIMS: To develop a five grade score (0-4 points) for the assessment of gastrointestinal (GI) dysfunction in adult critically ill patients. METHODS: This prospective multicenter observational study enrolled consecutive adult patients admitted to 11 intensive care units in nine countries. At all sites, daily clinical data with emphasis on GI clinical symptoms were collected and intra-abdominal pressure measured. In five out of 11 sites, the biomarkers citrulline and intestinal fatty acid-binding protein (I-FABP) were measured additionally. Cox models with time-dependent scores were used to analyze associations with 28- and 90-day mortality. The models were estimated with stratification for study center. RESULTS: We included 540 patients (224 with biomarker measurements) with median age of 65 years (range 18-94), the Simplified Acute Physiology Score II score of 38 (interquartile range 26-53) points, and Sequential Organ Failure Assessment (SOFA) score of 6 (interquartile range 3-9) points at admission. Median ICU length of stay was 3 (interquartile range 1-6) days and 90-day mortality 18.9%. A new five grade Gastrointestinal Dysfunction Score (GIDS) was developed based on the rationale of the previously developed Acute GI Injury (AGI) grading. Citrulline and I-FABP did not prove their potential for scoring of GI dysfunction in critically ill. GIDS was independently associated with 28- and 90-day mortality when added to SOFA total score (HR 1.40; 95%CI 1.07-1.84 and HR 1.40; 95%CI 1.02-1.79, respectively) or to a model containing all SOFA subscores (HR 1.48; 95%CI 1.13-1.92 and HR 1.47; 95%CI 1.15-1.87, respectively), improving predictive power of SOFA score in all analyses. CONCLUSIONS: The newly developed GIDS is additive to SOFA score in prediction of 28- and 90-day mortality. The clinical usefulness of this score should be validated prospectively. TRIAL REGISTRATION: NCT02613000, retrospectively registered 24 November 2015.

The prognostic value of the neutrophil-to-lymphocyte ratio in critically ill cirrhotic patients.

BACKGROUND: Hospital death rates following ICU admission of cirrhotic patients remain high. Identifying patients at high risk of mortality after few days of aggressive management is imperative for providing adequate interventions. Herein, we aimed to evaluate the prognostic value of the neutrophil-to-lymphocyte ratio (NLR) combined with usual organ failure scores in the outcome prediction of cirrhotic patients hospitalized more than 3 days in ICU. METHODS: We conducted a retrospective bicentric study in two cohorts of cirrhotic patients hospitalized more than 3 days in French university hospital ICUs. At admission and day 3, we calculated several clinico-biological scores grading liver disease and organ failure severity and calculated the NLR. The primary outcome was 28-day mortality. RESULTS: The test cohort included 116 patients. At day 28, 43 (37.1%) patients had died. Variations of MELD score (ΔMELD), SOFA score (ΔSOFA), CLIF-SOFA score (ΔCLIF-SOFA) and NLR (ΔNRL) between admission and day 3 were significantly associated with 28-day mortality in univariate analysis. When included in bivariate analysis ΔNLR remained a significant predictor of 28-day mortality independently of these severity scores. Kaplan-Meier curves and statistics using reclassification methods showed a better 28-day mortality risk prediction using ΔNRL in association with ΔSOFA in comparison to ΔSOFA alone. These results were confirmed in an external validation cohort, including 101 critically ill cirrhotic patients. CONCLUSIONS: ΔNLR is an independent predictor of mortality in the critically ill cirrhotic patients' population who requires intensive care supportive treatment and should be used in association with ΔSOFA as a prognostic biomarker.

Risk Factors and Impact of Perioperative Prophylaxis on the Risk of Extended-spectrum ß-Lactamase-producing Enterobacteriaceae-related Infection Among Carriers Following Liver Transplantation.

BACKGROUND: Extended-spectrum ß-lactamase-producing Enterobacteriaceae (ESBL-E) carriage is frequent among liver transplant (LT) recipients, thereby fostering a large empirical carbapenem prescription. However, ESBL-E infections occur in only 10%-25% of critically ill patients with rectal colonization. Our aim was to identify risk factors for post-LT ESBL-E infection in colonized patients. The effect of perioperative antimicrobial prophylaxis (AP) was also analyzed in patients with prophylaxis lasting <48 hours and without proven intraoperative infection. METHODS: Retrospective study from a prospective database including patients with a positive ESBL-E rectal screening transplanted between 2010 and 2016. RESULTS: Among the 749 patients transplanted, 100 (13.3%) were colonized with an ESBL-E strain. Thirty-nine (39%) patients developed an infection related to the same ESBL-E (10 pulmonary, 11 surgical site, 13 urinary, 5 bloodstream) within 11 postoperative days in median. Klebsiella pneumoniae carriage, model for end-stage liver disease ≥25, preoperative spontaneous bacterial peritonitis prophylaxis, and antimicrobial exposure during the previous month were independent predictors of ESBL-E infection. We propose a colonization to infection risk score built on these variables. The prevalence of infection for colonization to infection score of 0, 1, 2, and ≥3 were 7.4%, 26.3%, 61.9%, and 91.3%, respectively. Of note, the incidence of post-LT ESBL-E infection was lower in case of perioperative AP targeting colonizing ESBL-E (P = 0.04). CONCLUSIONS: Thirty-nine percentage of ESBL-E carriers develop a related infection after LT. We identified predictors for ESBL-E infection in carriers that may help in rationalizing carbapenem prescription. Perioperative AP targeting colonizing ESBL-E may be associated with a reduced risk of post-LT ESBL-E infections.

When Is a Critically Ill Cirrhotic Patient Too Sick to Transplant? Development of Consensus Criteria by a Multidisciplinary Panel of 35 International Experts.

BACKGROUND: Critically ill cirrhotic patients are increasingly transplanted, but there is no consensus about futile liver transplantation (LT). Therefore, the decision to delay or deny LT is often extensively debated. These debates arise from different opinions of futility among transplant team members. This study aims to achieve a multinational and multidisciplinary consensus on the definition of futility in LT and to develop well-articulated criteria for not proceeding with LT due to futility. METHODS: Thirty-five international experts from anesthesiology/intensive care, hepatology, and transplant surgery were surveyed using the Delphi method. More than 70% of similar answers to a question were necessary to define agreement. RESULTS: The panel recommended patient and graft survival at 1 year after LT to define futility. Severe frailty and persistent fever or <72 hours of appropriate antimicrobial therapy in case of ongoing sepsis were considered reasons to delay LT. A simple assessment of the number of organs failing was considered the most appropriate way to decide whether LT should be delayed or denied, with respiratory, circulatory and metabolic failures having the most influence in this decision. The thresholds of severity of organ failures contraindicating LT for which a consensus was achieved were a Pao2/FiO2 ratio<150 mm Hg, a norepinephrine dose >1 µg/kg per minute and a serum lactate level >9 mmol/L. CONCLUSIONS: Our expert panel provides a consensus on the definition of futile LT and on specific criteria for postponing or denying LT. A framework that may facilitate the decision if a patient is too sick for transplant is presented.

Predictive factors of severe abdominal pain during and after transarterial chemoembolization for hepatocellular carcinoma.

OBJECTIVES: To prospectively assess the frequency of severe abdominal pain during and after transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) using the visual analog scale (VAS), and to identify predictive factors. METHODS: Ninety-eight TACE performed in 80 patients (mean 65 ± 12 years old, 60 men) were consecutively and prospectively included. Abdominal pain was considered severe if the VAS ≥ 30/100 after treatment administration, or if opioid analgesic (grades 2-3) intake was required during hospitalization. Patient and tumor characteristics as well as technical factors associated with severe pain were identified by binary logistic regression. RESULTS: The criterion for severe pain was met in 41/98 (42%) of procedures (peri-procedural pain 30/98 [31%] and opioid consumption during hospitalization 24/98 [25%]). Multivariate analysis identified age (odds ratio [OR] = 0.943 (95% confidence interval 0.895-0.994), p = 0.029), cirrhosis (OR = 0.284 (0.083-0.971), p = 0.045), and alcoholic liver disease (OR = 0.081 (0.010-0.659), p = 0.019) as negative predictive factors of severe abdominal pain. Severe abdominal pain occurred in or after 1/13 (8%), 8/34 (24%), 22/41 (54%), and 10/10 (100%) TACE sessions when none, one, two, and three of the protective factors were absent, respectively (p < 0.001). The area under the ROC curve of the combination of factors for the prediction of severe abdominal pain was 0.779 (CI 0.687-0.871). CONCLUSION: Severe abdominal pain was frequent during and after TACE revealing a clinically relevant and underestimated problem. A predictive model based on three readily available clinical variables suggests that young patients without alcoholic liver disease or cirrhosis could benefit from reinforced analgesia. KEY POINTS: • Severe abdominal pain occurs in 43% of TACE for HCC. • Younger age, absence of cirrhosis, and absence of alcoholic liver disease were identified as independent predictive factors of severe abdominal pain. • A simple combination of the three abovementioned features helped predict the occurrence of severe abdominal pain.

Normal Lactate and Unenhanced CT-Scan Result in Delayed Diagnosis of Acute Mesenteric Ischemia.

INTRODUCTION: To investigate the factors associated with a delayed diagnosis (DD) of acute mesenteric ischemia (AMI). METHODS: An observational cohort study from an intestinal failure center. The primary outcome was DD >24 hours. RESULTS: Between 2006 and 2015, 74 patients with AMI were included and 39 (53%) had a DD. Plasma lactate <2 mmol/L (odd ratio: 3.2; 95% confidence interval: 1.1-9.1; P = 0.03) and unenhanced computed tomography scan (odds ratio: 5.9; 95% confidence interval: 1.4-25.8; P = 0.01) were independently associated with DD. DISCUSSION: Suspicion of AMI should no longer be affected by normal plasma lactate levels and should prompt evaluation by a contrast-enhanced computed tomography-scan.

Early hyperoxemia is associated with lower adjusted mortality after severe trauma: results from a French registry.

BACKGROUND: Hyperoxemia has been associated with increased mortality in critically ill patients, but little is known about its effect in trauma patients. The objective of this study was to assess the association between early hyperoxemia and in-hospital mortality after severe trauma. We hypothesized that a PaO2 ≥ 150 mmHg on admission was associated with increased in-hospital mortality. METHODS: Using data issued from a multicenter prospective trauma registry in France, we included trauma patients managed by the emergency medical services between May 2016 and March 2019 and admitted to a level I trauma center. Early hyperoxemia was defined as an arterial oxygen tension (PaO2) above 150 mmHg measured on hospital admission. In-hospital mortality was compared between normoxemic (150 > PaO2 ≥ 60 mmHg) and hyperoxemic patients using a propensity-score model with predetermined variables (gender, age, prehospital heart rate and systolic blood pressure, temperature, hemoglobin and arterial lactate, use of mechanical ventilation, presence of traumatic brain injury (TBI), initial Glasgow Coma Scale score, Injury Severity Score (ISS), American Society of Anesthesiologists physical health class > I, and presence of hemorrhagic shock). RESULTS: A total of 5912 patients were analyzed. The median age was 39 [26-55] years and 78% were male. More than half (53%) of the patients had an ISS above 15, and 32% had traumatic brain injury. On univariate analysis, the in-hospital mortality was higher in hyperoxemic patients compared to normoxemic patients (12% versus 9%, p < 0.0001). However, after propensity score matching, we found a significantly lower in-hospital mortality in hyperoxemic patients compared to normoxemic patients (OR 0.59 [0.50-0.70], p < 0.0001). CONCLUSION: In this large observational study, early hyperoxemia in trauma patients was associated with reduced adjusted in-hospital mortality. This result contrasts the unadjusted in-hospital mortality as well as numerous other findings reported in acutely and critically ill patients. The study calls for a randomized clinical trial to further investigate this association.

Women in Anaesthesia and Intensive Care Medicine in France: Are we making any progress?

INTRODUCTION: Gender imbalance in medicine is a topic of increasing interest. Gender matters, as there is increasing evidence that a gender diverse medical workforce translates into improved patient outcomes. The gender distribution in France among the Anaesthetists-Intensive Care (AIC) physicians has never been considered. METHODS: Gender distribution is described during the last two decades in France among the whole population of AIC physicians according to their age, professional activity, leading and academic position. RESULTS: The proportion of female AIC physicians remained stable from 1999 to 2018, between 35 and 38%. Only 40% of residents choosing this specialty in 2018 were female. Female AIC physicians were under-represented in key medico-political and academic positions: in 2018, 0.7% of the 605 presidents of medical commissions from public hospitals and none of the medical university deans were female AIC physicians; 9% of AIC full Professors were female. In the French Society of Anaesthesia and Intensive Care (SFAR), 42% of the members of the Scientific Committee of our Society are women. CONCLUSIONS: A gender imbalance is apparent in French AIC Medicine and worsens as physicians progress through their academic or leadership pathways. The French Society of Anaesthesia and Intensive Care campaigns for proportional representation at all levels of leadership, which translates into more gender equality in the committees of the society, including the Scientific Committee. A major policy shift is urgently required to support women, to tend toward gender parity to increase the performance of the French AIC workforce.

Use of Artificial Intelligence as an Innovative Method for Liver Graft Macrosteatosis Assessment.

The worldwide implementation of a liver graft pool using marginal livers (ie, grafts with a high risk of technical complications and impaired function or with a risk of transmitting infection or malignancy to the recipient) has led to a growing interest in developing methods for accurate evaluation of graft quality. Liver steatosis is associated with a higher risk of primary nonfunction, early graft dysfunction, and poor graft survival rate. The present study aimed to analyze the value of artificial intelligence (AI) in the assessment of liver steatosis during procurement compared with liver biopsy evaluation. A total of 117 consecutive liver grafts from brain-dead donors were included and classified into 2 cohorts: ≥30 versus <30% hepatic steatosis. AI analysis required the presence of an intraoperative smartphone liver picture as well as a graft biopsy and donor data. First, a new algorithm arising from current visual recognition methods was developed, trained, and validated to obtain automatic liver graft segmentation from smartphone images. Second, a fully automated texture analysis and classification of the liver graft was performed by machine-learning algorithms. Automatic liver graft segmentation from smartphone images achieved an accuracy (Acc) of 98%, whereas the analysis of the liver graft features (cropped picture and donor data) showed an Acc of 89% in graft classification (≥30 versus <30%). This study demonstrates that AI has the potential to assess steatosis in a handy and noninvasive way to reliably identify potential nontransplantable liver grafts and to avoid improper graft utilization.

Liver transplantation for critically ill cirrhotic patients: Stratifying utility based on pretransplant factors.

The aim of this study was to produce a prognostic model to help predict posttransplant survival in patients transplanted with grade-3 acute-on-chronic liver failure (ACLF-3). Patients with ACLF-3 who underwent liver transplantation (LT) between 2007 and 2017 in 5 transplant centers were included (n = 152). Predictors of 1-year mortality were retrospectively screened and tested on a single center training cohort and subsequently tested on an independent multicenter cohort composed of the 4 other centers. Four independent pretransplant risk factors were associated with 1-year mortality after transplantation in the training cohort: age ≥53 years (P = .044), pre-LT arterial lactate level ≥4 mml/L (P = .013), mechanical ventilation with PaO2 /FiO2  ≤ 200 mm Hg (P = .026), and pre-LT leukocyte count ≤10 G/L (P = .004). A simplified version of the model was derived by assigning 1 point to each risk factor: the transplantation for Aclf-3 model (TAM) score. A cut-off at 2 points distinguished a high-risk group (score >2) from a low-risk group (score ≤2) with 1-year survival of 8.3% vs 83.9% respectively (P < .001). This model was subsequently validated in the independent multicenter cohort. The TAM score can help stratify posttransplant survival and identify an optimal transplantation window for patients with ACLF-3.
