Treatment of COVID-19-associated ARDS with umbilical cord-derived mesenchymal stromal cells in the STROMA-CoV-2 multicenter randomized double-blind trial: long-term safety, respiratory function, and quality of life.

BACKGROUND: The STROMA-CoV-2 study was a French phase 2b, multicenter, double-blind, randomized, placebo-controlled clinical trial that did not identify a significant efficacy of umbilical cord-derived mesenchymal stromal cells in patients with SARS-CoV-2-induced acute respiratory distress syndrome. Safety on day 28 was found to be good. The aim of our extended study was to assess the 6- and 12-month safety of UC-MSCs administration in the STROMA-CoV-2 cohort. METHODS: A detailed multi-domain assessment was conducted at 6 and 12 months following hospital discharge focusing on adverse events, lung computed tomography-scan, pulmonary and muscular functional status, and quality of life in the STROMA-CoV-2 cohort including SARS-CoV-2-related early (< 96 h) mild-to-severe acute respiratory distress syndrome. RESULTS: Between April 2020 and October 2020, 47 patients were enrolled, of whom 19 completed a 1-year follow-up. There were no significant differences in any endpoints or adverse effects between the UC-MSCs and placebo groups at the 6- and 12-month assessments. Ground-glass opacities persisted at 1 year in 5 patients (26.3%). Furthermore, diffusing capacity for carbon monoxide remained altered over 1 year, although no patient required oxygen or non-invasive ventilatory support. Quality of life revealed declines in mental, emotional and physical health throughout the follow-up period, and the six-minute walking distance remained slightly impaired at the 1-year patient assessment. CONCLUSIONS: This study suggests a favorable safety profile for the use of intravenous UC-MSCs in the context of the first French wave of SARS-CoV-2-related moderate-to-severe acute respiratory distress syndrome, with no adverse effects observed at 1 year.

Case 327.

HISTORY: A 58-year-old man who was an active smoker was admitted twice to the intensive care unit (ICU) of a tertiary referral thoracic center for severe hypercapnic acute respiratory failure and persistent bilateral chest radiograph opacities that were unchanged over the course of the two ICU admissions within a 3-month period (Fig 1). He had obesity (body mass index, 36 kg/m2), stage 3 vascular chronic renal insufficiency, and hebephrenic schizophrenia treated with haloperidol, carbamazepine, and cyamemazine. He reported chronic dyspnea on exertion, which worsened for 6 months. At the second ICU admission, he was afebrile, with a blood pressure of 160/72 mm Hg and pulse oximetry of 93% on 6 L/min oxygen therapy through a nonrebreathing mask. Physical examination showed signs of respiratory failure with wheezing and active abdominal expiration, bilateral pulmonary crackles without chest pain, hemoptysis, clubbing, or signs of cardiac failure. He had no peripheral lymphadenopathy and no enlarged spleen. Blood gases (on 6 L/min oxygen) showed respiratory acidosis (pH, 7.15 [normal range, 7.38-7.42]; Pao2 level, 67 mm Hg [normal range, 80-100 mm Hg]; Paco2 level, 102 mm Hg [normal range, 38-42 mm Hg]; Hco3- level, 29 mmol/L [normal range, 22-27 mmol/L]). Noninvasive ventilation was initiated. Imaging performed during the second ICU hospitalization included noncontrast chest CT (Fig 2), MRI of the chest without contrast enhancement (Fig 3), and fluorine 18 fluorodeoxyglucose PET/CT (Fig 4).

Prediction of esophagogastroduodenoscopy therapeutic usefulness for in-ICU suspected upper gastrointestinal bleeding: the SUGIBI score study.

BACKGROUND: Suspected upper gastrointestinal bleeding (SUGIB) is a common issue during ICU stay. In the absence of specific guidelines on the indication and timing of esophagogastroduodenoscopy (EGD), there is substantial variability in EGD indication depending on accessibility and clinical presentation. This study aimed to investigate factors associated with the need for per-EGD hemostatic therapy and to create a score predicting therapeutic benefit of emergency bedside EGD in ICU patients with SUGIB. METHODS: We conducted a retrospective study in our ICU to identify factors associated with the need for hemostatic procedure during EGD performed for SUGIB. From this observational cohort, we derived a score predicting the need for hemostasis during EGD, the SUGIBI score. This score was subsequently validated in a retrospective multicenter cohort. RESULTS: Two hundred fifty-five patients not primarily admitted for GI bleeding who underwent a bedside EGD for SUGIB during their ICU stay were analyzed. The preeminent EGD indication were anemia (79%), melena (19%), shock (14%), and hematemesis (13%). EGD was normal in 24.7% of cases, while primary lesions reported were ulcers (23.1%), esophagitis (18.8%), and gastritis (12.5%). Only 12.9% of patients underwent hemostatic endotherapy during EGD. A SUGIBI score < 4 had a negative predictive value of 95% (91-99) for hemostatic endotherapy [AUC of 0.81; 0.75-0.91 (p < 0.0001)]. The SUGIBI score for predicting the need for an EGD-guided hemostatic procedure was next validated in a multicenter cohort with an AUC of 0.75 (0.66-0.85) (p < 0.0001), a score < 4 having a negative predictive value of 95% (92-97). CONCLUSIONS: Our study shows that the therapeutic usefulness of bedside emergency EGD for SUGIB in critically ill patients is limited to a minority of patients. The SUGIBI score should help clinicians stratify the probability of a therapeutic EGD.

High Airway Occlusion Pressure Is Associated with Dyspnea and Increased Mortality in Critically Ill Mechanically Ventilated Patients.

RATIONALE: 100 ms airway occlusion pressure (P0.1) reflects central respiratory drive. We aimed to assess factors associated with P0.1 and whether an abnormally low or high P0.1 value is associated with higher mortality and longer duration of mechanical ventilation (MV). METHODS: Secondary analysis of a prospective cohort study conducted in 10 intensive care units in France to evaluate dyspnea in communicative MV patients. In patients intubated for more than 24 hours, P0.1 was measured with dyspnea as soon as patients could communicate and the following day. RESULTS: 260 patients were assessed after a median time of ventilation of 4 days. P0.1 was 1.9 (1 - 3.5) cmH2O on enrollment, 24% had a P0.1 >3.5 cmH2O, 37% had a P0.1 between 1.5 and 3.5 cmH2O, and 39% had a P0.1 <1.5 cmH2O. In multivariable linear regression, independent factors associated with P0.1 level were presence of dyspnea (p=0.037), respiratory rate (p<0.001), and PaO2 (p=0.008). 90-day mortality was 33% in patients with P0.1 >3.5 cmH2O vs. 19% in those with a P0.1 between 1.5 and 3.5 cmH2O and 17% in patients with P0.1 <1.5 cmH2O (p=0.046). After adjustment for the main risk factors, P0.1 was associated with 90-day mortality (per cmH2O of P0.1, Hazard ratio 1.19, 95% Confidence interval 1.04 - 1.37, p=0.011). P0.1 was also independently associated with a longer duration of MV (per cmH2O of P0.1, Hazard ratio 1.10, 95% Confidence interval 1.02-1.19, p=0.016). CONCLUSIONS: In patients receiving invasive mechanical ventilation, abnormally high P0.1 values may suggest dyspnea and is associated with higher mortality and prolonged duration of MV.

Corticosteroids induce an early but limited decrease in IL-6 dependent pro-inflammatory responses in critically ill COVID-19 patients.

BACKGROUND: Corticosteroids have become standard of care for COVID-19 but their effect on the systemic immune-inflammatory response has been little investigated. METHODS: Multicenter prospective cohort, including critically ill COVID-19 patients between March and November 2020. C-reactive protein (CRP), lymphocyte count and fibrinogen levels were collected upon hospital admission before initiation of steroid treatment and at ICU admission, three days and seven days later, along with interleukin (IL)-6, IL-10 and tumor necrosis factor-alpha (TNF-α) plasma levels. RESULTS: A hundred and fifty patients were included, 47 received corticosteroids, 103 did not. Median age was 62 [53-70], and 96 (65%) patients were mechanically ventilated. Propensity score matching rendered 45 well-balanced pairs of treated and non-treated patients, particularly on pre-treatment CRP levels. Using a mixed model, CRP (P=0.019), fibrinogen (P=0.003) and lymphocyte counts (P=0.006) remained lower in treated patients over ICU stay. Conversely, there was no significant difference over the ICU stay for Il-6 (P=0.146) and IL-10 (0.301), while TNF- α levels were higher in the treated group (P=0.013). Among corticosteroid-treated patients, CRP (P=0.012), fibrinogen (P=0.041) and lymphocyte count (P=0.004) over time were associated with outcome, whereas plasma cytokine levels were not. CONCLUSIONS: Steroid treatment was associated with an early and sustained decrease in the downstream IL-6-dependent inflammatory signature but an increase in TNF-α levels. In corticosteroid-treated patients, CRP and lymphocyte count were associated with outcome, conversely to plasma cytokine levels. Further research on using these biomarker's kinetics to individualize immunomodulatory treatments is warranted.

Diagnostic yield of viral multiplex PCR during acute exacerbation of COPD admitted to the intensive care unit: a pilot study.

Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is one of the leading causes of admission to the intensive care unit, often triggered by a respiratory tract infection of bacterial or viral aetiology. Managing antibiotic therapy in this context remains a challenge. Respiratory panel molecular tests allow identifying viral aetiologies of AECOPD. We hypothesized that the systematic use of a respiratory multiplex PCR (mPCR) would help antibiotics saving in severe AECOPD. Our objectives were to describe the spectrum of infectious aetiologies of severe AECOPD, using a diagnostic approach combining conventional diagnostic tests and mPCR, and to measure antibiotics exposure. The study was bicentric, prospective, observational, and included 105 critically ill patients with a severe AECOPD of presumed infectious aetiology, in whom a respiratory mPCR with a viral panel was performed in addition to conventional microbiological tests. Altogether, the microbiological documentation rate was 50%, including bacteria alone (19%), respiratory viruses alone (16%), and mixed viruses and bacterial species (16%). The duration of antibiotic therapy was shorter in patients without documented bacterial infection (5.6 vs. 9 days; P = 0.0006). This pilot study suggests that molecular tests may help for the proper use of anti-infective treatments in critically ill patients with severe AECOPD.

Low-flow ECCO2R conjoined with renal replacement therapy platform to manage pulmonary vascular dysfunction with refractory hypercapnia in ARDS.

Background: Hypercapnia worsens lung vascular dysfunction during acute respiratory distress syndrome (ARDS). We tested whether an extracorporeal carbon dioxide removal (ECCO2R) device based on a renal replacement therapy platform (Prismalung®) may reduce PaCO2 and alleviate lung vascular dysfunction in ARDS patients with refractory hypercapnia. Methods: We planned to prospectively include 20 patients with moderate-to-severe ARDS, pulmonary vascular dysfunction on echocardiography, and PaCO2 ≥ 48 mmHg despite instrumental dead space reduction and the increase in respiratory rate. Hemodynamics, echocardiography, respiratory mechanics, and arterial blood gases were recorded at 2 (H2), 6 (H6) and 24 (H24) hours as ECCO2R treatment was continued for at least 24 h. Results: Only eight patients were included, and the study was stopped due to worldwide shortage of ECCO2R membranes and the pandemic. Only one patient fulfilled the primary endpoint criterion (decrease in PaCO2 of more than 20 %) at H2, but this objective was achieved in half of patients (n = 4) at H6. The percentage of patients with a PaCO2 value < 48 mmHg increased with time, from 0/8 (0 %) at H0, to 3/8 (37.5 %) at H2 and 4/8 (50 %) at H6 (p = 0.04). There was no major change in hemodynamic and echocardiographic variables with ECCO2R, except for a significant decrease in heart rate. ECCO2R was prematurely discontinued before H24 in five (62.5 %) patients, due to membrane clotting in all cases. Conclusions: This pilot study testing showed a narrow efficacy and high rate of membrane thrombosis with the first version of the system. Improved versions should be tested in future trials.

In-hospital outcomes after acute myocardial infarction with obstructive coronary artery disease in critically ill patients hospitalized for non-cardiac disease.

BACKGROUND: Acute myocardial infarction (AMI) is one of the major cardiac complications in patients hospitalized in the intensive care unit (ICU) for non-cardiac disease. A better knowledge of ischemic and bleeding risks in these patients is needed to identify those most likely to benefit from specific cardiac management. We therefore assessed the incidence and predictors of a composite outcome of severe ischemic event (AMI recurrence, ischemic stroke), major bleeding, or all-cause death in this setting. METHODS: In this multicenter retrospective study, all consecutive adult patients admitted for non-cardiac disease to four French university hospital ICUs between January 2012 and December 2018 who had an AMI with obstructive coronary artery disease (OCAD) during the ICU stay were considered for inclusion. AMI with OCAD was defined as an elevated cardiac troponin value associated with at least one sign (clinical, electrocardiographic, or echocardiographic) suggestive of myocardial ischemia and presence of OCAD on coronary angiography. The primary endpoint was in-hospital occurrence of the composite outcome. RESULTS: Ninety-six patients [median age 69 years, 22 women (23%), 59 with sepsis (61%), 35 with ST elevation (37%), median sequential organ failure assessment (SOFA) of 8 on the day of AMI] were included. The median peak cardiac troponin value was 131 (IQR 44-303) times the upper reference limit. Dual antiplatelet, therapeutic anticoagulation, and early mechanical reperfusion therapies were administered in 61 (64%), 68 (71%), and 47 (49%) patients, respectively. The composite outcome occurred in 48 (50%) patients. Severe ischemic events occurred in 17 (18%) patients and major bleeding in 26 (27%) patients; 26 patients (27%) died in the hospital. AMI management was not significantly different in patients with and without the composite outcome. A history of arterial hypertension (HR 2.05, 95% CI 1.01-4.16) and high SOFA score at the time of AMI (HR 1.07, 95% CI 1.00-1.15) were independent risk factors for the composite outcome. CONCLUSIONS: Patients who have an AMI with OCAD during an ICU stay for non-cardiac disease are at risk of a composite outcome of severe ischemia, major bleeding, and death. A history of arterial hypertension and high SOFA scores were independent hazards for poor prognosis.

Clinical relevance and prognostic value of renal Doppler in acute decompensated precapillary pulmonary hypertension.

AIMS: We aim to evaluate the clinical relevance and the prognostic value of arterial and venous renal Doppler in acute decompensated precapillary pulmonary hypertension (PH). METHODS AND RESULTS: The renal resistance index (RRI) and the Doppler-derived renal venous stasis index (RVSI) were monitored at admission and on Day 3 in a prospective cohort of precapillary PH patients managed in intensive care unit for acute right heart failure (RHF). The primary composite endpoint included death, circulatory assistance, urgent transplantation, or rehospitalization for acute RHF within 90 days following inclusion. Ninety-one patients were enrolled (58% female, age 58 ± 16 years). The primary endpoint event occurred in 32 patients (33%). In univariate logistic regression analysis, variables associated with RRI higher than the median value were non-variable parameters (age and history of hypertension), congestion (right atrial pressure and renal pulse pressure), cardiac function [tricuspid annular plane systolic excursion (TAPSE) and left ventricular outflow tract- velocity time integral], systemic pressures and NT-proBNP. Variables associated with RVSI higher than the median value were congestion (high central venous pressure, right atrial pressure, and renal pulse pressure), right cardiac function (TAPSE), severe tricuspid regurgitation, and systemic pressures. Inotropic support was more frequently required in patients with high RRI (P = 0.01) or high RVSI (P = 0.003) at the time of admission. At Day 3, a RRI value <0.9 was associated with a better prognosis after adjusting to the estimated glomerular filtration rate. CONCLUSION: Renal Doppler provides additional information to assess the severity of patients admitted to the intensive care unit for acute decompensated precapillary PH.

Surgical and perioperative management of flail chest with titanium plates: a French cohort series from a thoracic referral center.

BACKGROUND: The development of titanium claw plates has made rib osteosynthesis easy to achieve and led to a renewed interest for this surgery. We report the management of patients referred to the intensive care unit (ICU) of a referral center for surgical rib fracture fixation (SRFF) after chest trauma. METHODS: We performed a retrospective observational cohort study describing the patients' characteristics and analyzing the determinants of postoperative complications. RESULTS: From November 2013 to December 2016, 42 patients were referred to our center for SRFF: 12 patients (29%) had acute respiratory failure, 6 of whom received invasive mechanical ventilation. The Thoracic Trauma Severity Score (TTSS) was 11.0 [9-12], with 7 [5-9] broken ribs and a flail chest in 92% of cases. A postoperative complication occurred in 18 patients (43%). Five patients developed ARDS (12%). Postoperative pneumonia occurred in 11 patients (26%). Two patients died in the ICU. In multivariable analysis, the Thoracic Trauma Severity Score (TTSS) (OR = 1.89; CI 95% 1.12-3.17; p = 0.016) and the Simplified Acute Physiology Score II without age (OR = 1.17; CI 95% 1.02-1.34; p = 0.024) were independently associated with the occurrence of a postoperative complication. CONCLUSION: The TTSS score appears to be accurate for determining thoracic trauma severity. Short and long-term benefit of Surgical Rib Fracture Fixation should be assessed, particularly in non-mechanically ventilated patients.

Respiratory multiplex PCR and procalcitonin to reduce antibiotic exposure in severe SARS-CoV-2 pneumonia: a multicentre randomized controlled trial.

OBJECTIVES: We aimed at assessing the efficacy and safety on antibiotic exposure of a strategy combining a respiratory multiplex PCR (mPCR) with enlarged panel and daily procalcitonin (PCT) measurements, as compared with a conventional strategy, in adult patients who were critically ill with laboratory-confirmed SARS-CoV-2 pneumonia. METHODS: This multicentre, parallel-group, open-label, randomized controlled trial enrolled patients admitted to 13 intensive care units (ICUs) in France. Patients were assigned (1:1) to the control strategy, in which antibiotic streamlining remained at the discretion of the physicians, or interventional strategy, consisting of using mPCR and daily PCT measurements within the first 7 days of randomization to streamline initial antibiotic therapy, with antibiotic continuation encouraged when PCT was >1 ng/mL and discouraged if < 1 ng/mL or decreased by 80% from baseline. All patients underwent conventional microbiological tests and cultures. The primary end point was antibiotic-free days at day 28. RESULTS: Between April 20th and November 23rd 2020, 194 patients were randomized, of whom 191 were retained in the intention-to-treat analysis. Respiratory bacterial co-infection was detected in 48.4% (45/93) and 21.4% (21/98) in the interventional and control group, respectively. The number of antibiotic-free days was 12.0 (0.0; 25.0) and 14.0 (0.0; 24.0) days, respectively (difference, -2.0, (95% CI, -10.6 to 6.6), p=0.89). Superinfection rates were high (51.6% and 48.5%, respectively). Mortality rates and ICU lengths of stay did not differ between groups. DISCUSSION: In severe SARS-CoV-2 pneumonia, the mPCR/PCT algorithm strategy did not affect 28-day antibiotics exposure nor the major clinical outcomes, as compared with routine practice.

Feasibility of a repositioning schedule on pressure ulcer prevention in a French Intensive Care Unit: A pre and post-intervention pilot study.

AIMS: As a prerequisite of a multicentre study, we conducted a pilot study to assess the feasibility of a daily repositioning schedule in critically ill patients. The schedule was adapted to the patient's clinical condition, and the estimated risk for developing a pressure ulcer using the Braden scale. DESIGN: A single-center pre and post-intervention pilot study in a French Intensive Care Unit of a university teaching hospital. This study followed TREND guidelines. METHODS: During the first period (March to May 2018), pressure ulcer prevention was performed according to usual care. During the second period (June to August 2018), the repositioning schedule was adapted to the estimated risk for developing a pressure ulcer according to the Braden scale. Eligible patients had no pressure ulcer at baseline, were intubated within 24 hours of admission and expected to receive mechanical ventilation for at least 24 hours. The primary outcome was the rate of pressure ulcer development at 28 days of hospitalization or at discharge or death, as compared with usual care. Secondary outcomes included the feasibility and safety of the schedule, as assessed by caregivers' adherence and workload, and the rate of adverse events. RESULTS: In the pre-intervention period 20 participants were included, and 14 patients were included in the post-intervention period. There was no decrease in the pressure ulcers incidence with the intervention (25% vs. 28.6%; P = 1). The number of daily repositioning performed increased from 3.3 [IQR 3.0; 3.9] during the pre-intervention period to 4.3 [IQR 3.8; 5.2] during the post-intervention period (P < 0.05), where it differed from the number scheduled by 0.6 [IQR 0.1; 1.4] per day, indicating satisfactory adherence of caregivers to the protocol. Adverse events rate did not differ between the two periods (55.9% vs. 57.1%; P = 0.90). CONCLUSION: A personalised daily repositioning schedule in critically ill patients is feasible and safe. The efficacy of such a strategy, together with its economic impact, need to be assessed in a multicentre randomized trial.

Spontaneous pneumomediastinum: a surrogate of P-SILI in critically ill COVID-19 patients.

Spontaneous pneumomediastinum (SP) has been described early during the COVID-19 pandemic in large series of patients with severe pneumonia, but most patients were receiving invasive mechanical ventilation (IMV) at the time of SP diagnosis. In this retrospective multicenter observational study, we aimed at describing the prevalence and outcomes of SP during severe COVID-19 with pneumonia before any IMV, to rule out mechanisms induced by IMV in the development of pneumomediastinum.Among 549 patients, 21 patients (4%) developed a SP while receiving non-invasive respiratory support, after a median of 6 days [4-12] from ICU admission. The proportion of patients requiring IMV was similar. However, the time to tracheal intubation was longer in patients with SP (6 days [5-13] vs. 2 days [1-4]; P = 0.00002), with a higher first-line use of non-invasive ventilation (n = 11; 52% vs. n = 150; 28%; P = 0.02). The 21 patients who developed a SP had persisting signs of severe lung disease and respiratory failure with lower ROX index between ICU admission and occurrence of SP (3.94 [3.15-5.55] at admission vs. 3.25 [2.73-4.02] the day preceding SP; P = 0.1), which may underline potential indirect signals of Patient-self inflicted lung injury (P-SILI).In this series of critically ill COVID-19 patients, the prevalence of SP without IMV was not uncommon, affecting 4% of patients. They received more often vasopressors and had a longer ICU length of stay, as compared with their counterparts. One pathophysiological mechanism may potentially be carried out by P-SILI related to a prolonged respiratory failure, as underlined by a delayed use of IMV and the evolution of the ROX index between ICU admission and the day preceding SP.

Diagnosis and prognosis of acute respiratory distress syndrome related to diffuse pneumonic-type adenocarcinoma: a single-center case series study.

Background: The absence of diagnosis of acute respiratory distress syndrome (ARDS) concerns 20% of cancer patients and is associated with poorer outcomes. Diffuse pneumonic-type adenocarcinoma (P-ADC) is part of these difficult-to-diagnose ARDS, but only limited data are available regarding critically ill patients with diffuse P-ADC. We sought to describe the diagnosis process and the prognosis of P-ADC related ARDS patients admitted to the intensive care unit (ICU). Methods: Single-center observational case series study. All consecutive patients admitted to the ICU over a two-decade period presenting with (I) histologically or cytologically proven adenocarcinoma of the lung and (II) ARDS according to Berlin definition were included. Clinical, biological, radiological and cytological features of P-ADC were collected to identify diagnostic clues. Multivariate logistic regression analyses were performed to assess factors associated with ICU and hospital mortality. Results: Among the 24 patients included [70 (61-75) years old, 17 (71%) males], the cancer diagnosis was performed during the ICU stay in 19 (79%), and 17 (71%) required mechanical ventilation. The time between the first symptoms and the diagnosis of P-ADC was 210 days (92-246 days). A non-resolving pneumonia after 2 (2 to 3) antibiotics lines observed in 23 (96%) patients with a 34 mg/L (19 to 75 mg/L) plasma C-reactive protein level at ICU admission. Progressive dyspnea, bronchorrhea, salty expectoration, fissural bulging and compressed bronchi and vessels were present in 100%, 83%, 69%, 57% and 43% of cases. Cytological examination of sputum or broncho-alveolar lavage provided a 75% diagnostic yield. The ICU and hospital mortality rates were 25% and 63%, respectively. The time (in days) between first symptoms and diagnosis [odds ratio (OR) 1.02, 95% confidence interval (95% CI): 1.00-1.03, P=0.046] and the Simplified Acute Physiology Score II (OR 1.16, 95% CI: 1.01-1.33, P=0.040) were independently associated with ICU mortality. Conclusions: Non-resolving pneumonia after several antibiotics lines without inflammatory syndrome, associated with progressive dyspnea, salty bronchorrhea, and lobar swelling (i.e., fissural bulging, compressed bronchi and vessels) were suggestive of P-ADC. Delayed diagnosis of diffuse P-ADC seemed an independent prognostic predictor and disease timely recognition may contribute to prognosis improvement.

Ten actions to achieve gender equity among intensivists: the French Society of Intensive Care (FICS) model.

In our recent survey, we aimed to collect information on perceived inequity as well as professional and personal fulfillment among women intensivists in France. For the 371 respondents out of the 732 persons who received the survey, the findings were unequivocal: for one-third of the respondents, being a woman was considered as an obstacle to careers or academic advancement, and for two thirds, pregnancy was viewed as a barrier to their career advancement. Gender discrimination had been experienced by 55% of the respondents. In 2019, to promote and achieve gender equity in the French Intensive Care Society (FICS), ten actions were initiated and are detailed in the present manuscript together with supporting data: (1) creation of a working group: the FEMMIR group; (2) promotion of mentorship; (3) implementation of concrete sponsorship; (4) transparency and public reporting of gender ratios in editorial boards; (5) workshops dedicated to unconscious gender bias; (6) workshops dedicated to improved women assertiveness; (7) role models; (8) creation of educational/information programs for young intensivists; (9) development of research on gender inequity and, as a perspective; and (10) development of a wide-ranging program. This review is aimed at providing a toolbox of organizational best practices designed to achieve gender equity. It is particularly important to share promising practical action engaged in our FEMMIR group with other concerned professionals around the world.

ICU strain and outcome in COVID-19 patients-A multicenter retrospective observational study.

PURPOSE: To compare the characteristics, management, and prognosis of patients admitted to intensive care units (ICU) for coronavirus disease (COVID)-19 during the first two waves of the outbreak and to evaluate the relationship between ICU strain (ICU demand due to COVID-19 admissions) and mortality. METHODS: In a multicentre retrospective study, 1166 COVID-19 patients admitted to five ICUs in France between 20 February and 31 December 2020 were included. Data were collected at each ICU from medical records. A Cox proportional-hazards model identified factors associated with 28-day mortality. RESULTS: 640 patients (55%) were admitted during the first wave (February to June 2020) and 526 (45%) during the second wave (July to December 2020). ICU strain was lower during the second wave (-0.81 [-1.04 --0.31] vs. 1.18 [-0.34-1.29] SD when compared to mean COVID-19 admission in each center during study period, P<0.001). Patients admitted during the second wave were older, had more profound hypoxemia and lower SOFA. High flow nasal cannula was more frequently used during the second wave (68% vs. 39%, P<0.001) and intubation was less frequent (46% vs. 69%, P<0.001). Neither 28-day mortality (30% vs. 26%, P = 0.12) nor hospital mortality (37% vs. 31%, P = 0.27) differed between first and second wave. Overweight and obesity were associated with lower 28-day mortality while older age, underlying chronic kidney disease, severity at ICU admission as assessed by SOFA score and ICU strain were associated with higher 28-day mortality. ICU strain was not associated with hospital mortality. CONCLUSION: The characteristics and the management of patients varied between the first and the second wave of the pandemic. Rather than the wave, ICU strain was independently associated with 28-day mortality, but not with hospital mortality.

Prognostic performance of GRACE and TIMI risk scores in critically ill patients with sepsis and a concomitant myocardial infarction.

BACKGROUND: Identifying which patients with acute myocardial infarction (AMI) during sepsis are at risk of poor outcome is a clinical challenge. AIM: To evaluate Global Registry of Acute Coronary Events (GRACE) and Thrombolysis In Myocardial Infarction (TIMI) risk scores to predict in-hospital mortality and severe ischaemic events in this setting. METHODS: In this single-centre retrospective study conducted from 2012 to 2016, all consecutive adults hospitalized in the intensive care unit for sepsis who had a concomitant AMI (within 72hours of admission) were enrolled. AMI was defined by an elevated cardiac troponin I value associated with at least one sign (clinical, electrocardiographic or echocardiographic) suggestive of myocardial ischaemia. The primary outcome was in-hospital mortality from any cause. Secondary outcomes were in-hospital occurrence of severe ischaemic events (cardiac arrest with resuscitation, ischaemic stroke and myocardial reinfarction) and major bleeding events. RESULTS: Among 856 patients hospitalized for sepsis, 120 (14.5%) had a concomitant AMI (37.5% women; median age 65 years; median Sequential Organ Failure Assessment [SOFA] score 8). Severe ischaemic events occurred in 15 patients (12.5%), and 39 (33%) died in hospital. Neither the GRACE score (median 192, interquartile range 154-223) nor the TIMI score (median 3, interquartile range 2-4) was associated with occurrence of severe ischaemic events. Only the GRACE score was associated with in-hospital mortality (odds ratio 1.01, 95% confidence interval 1.00-1.02 per 1 point increase). Multivariable analysis identified previous aspirin use and SOFA score as independent factors associated with in-hospital mortality. CONCLUSIONS: GRACE and TIMI scores did not predict in-hospital severe ischaemic events and mortality in patients with AMI during sepsis. Among individual components of both scores, previous aspirin use was associated with poor prognosis. However, because of lack of statistical power, we cannot formally rule out the usefulness of these scores in this setting.
