RESUMEN

BACKGROUND: Whether the route of early feeding affects outcomes of patients with severe critical illnesses is controversial. We hypothesised that outcomes were better with early first-line enteral nutrition than with early first-line parenteral nutrition. METHODS: In this randomised, controlled, multicentre, open-label, parallel-group study (NUTRIREA-2 trial) done at 44 French intensive-care units (ICUs), adults (18 years or older) receiving invasive mechanical ventilation and vasopressor support for shock were randomly assigned (1:1) to either parenteral nutrition or enteral nutrition, both targeting normocaloric goals (20-25 kcal/kg per day), within 24 h after intubation. Randomisation was stratified by centre using permutation blocks of variable sizes. Given that route of nutrition cannot be masked, blinding of the physicians and nurses was not feasible. Patients receiving parenteral nutrition could be switched to enteral nutrition after at least 72 h in the event of shock resolution (no vasopressor support for 24 consecutive hours and arterial lactate <2 mmol/L). The primary endpoint was mortality on day 28 after randomisation in the intention-to-treat-population. This study is registered with ClinicalTrials.gov, number NCT01802099. FINDINGS: After the second interim analysis, the independent Data Safety and Monitoring Board deemed that completing patient enrolment was unlikely to significantly change the results of the trial and recommended stopping patient recruitment. Between March 22, 2013, and June 30, 2015, 2410 patients were enrolled and randomly assigned; 1202 to the enteral group and 1208 to the parenteral group. By day 28, 443 (37%) of 1202 patients in the enteral group and 422 (35%) of 1208 patients in the parenteral group had died (absolute difference estimate 2·0%; [95% CI -1·9 to 5·8]; p=0·33). Cumulative incidence of patients with ICU-acquired infections did not differ between the enteral group (173 [14%]) and the parenteral group (194 [16%]; hazard ratio [HR] 0·89 [95% CI 0·72-1·09]; p=0·25). Compared with the parenteral group, the enteral group had higher cumulative incidences of patients with vomiting (406 [34%] vs 246 [20%]; HR 1·89 [1·62-2·20]; p<0·0001), diarrhoea (432 [36%] vs 393 [33%]; 1·20 [1·05-1·37]; p=0·009), bowel ischaemia (19 [2%] vs five [<1%]; 3·84 [1·43-10·3]; p=0·007), and acute colonic pseudo-obstruction (11 [1%] vs three [<1%]; 3·7 [1·03-13·2; p=0·04). INTERPRETATION: In critically ill adults with shock, early isocaloric enteral nutrition did not reduce mortality or the risk of secondary infections but was associated with a greater risk of digestive complications compared with early isocaloric parenteral nutrition.

RESUMEN

OBJECTIVES: To identify the factors associated with the interindividual pharmacokinetic (PK) variability of micafungin and to evaluate the probability of reaching the previously determined PK/pharmacodynamic efficacy thresholds (AUC/MIC >5000 for non-parapsilosis Candida sp. and ≥285 for Candida parapsilosis) with the recommended 100 mg daily dose in ICU patients with sepsis and mechanical ventilation. METHODS: One hundred patients were included and 436 concentrations were available for PK analysis performed with NONMEM software. PTA was determined by Monte Carlo simulations. RESULTS: Micafungin obeyed a two-compartment model with first-order elimination from the central compartment. Mean parameter estimates (percentage interindividual variability) were 1.34 L/h (34%) for clearance (CL), 11.80 L (38%) and 7.68 L (39%) for central (Vc) and peripheral (Vp) distribution volumes, respectively, and 4.67 L/h (37%) for distribution clearance. CL, Vc and Vp increased by 14% when the albumin level was ≤25 g/L and CL decreased by 25% when SOFA score was ≥10. Body weight was related to CL, Vc and Vp by allometric models. PTA was ≥90% in Candida albicans and Candida glabrata infections, except when the MIC was ≥0.015 mg/L, and ranged between 0% and 40% for C. parapsilosis infections with MIC ≥0.5 mg/L. CONCLUSIONS: A possible increase in the dose should be evaluated for infections due to C. parapsilosis and for infections due to C. albicans and C. glabrata with MICs ≥0.015 mg/L.

RESUMEN

BACKGROUND: The outcomes of patients admitted to the intensive care unit (ICU) for acute manifestation of small-vessel vasculitis are poorly reported. The aim of the present study was to determine the mortality rate and prognostic factors of patients admitted to the ICU for acute small-vessel vasculitis. METHODS: This retrospective, multicenter study was conducted from January 2001 to December 2014 in 20 ICUs in France. Patients were identified from computerized registers of each hospital using the International Classification of Diseases, Ninth Revision (ICD-9). Inclusion criteria were (1) known or highly suspected granulomatosis with polyangiitis, eosinophilic granulomatosis with polyangiitis, microscopic polyangiitis (respectively, ICD-9 codes M31.3, M30.1, and M31.7), or anti-glomerular basement membrane antibody disease (ICD-9 codes N08.5X-005 or M31.0+); (2) admission to the ICU for the management of an acute manifestation of vasculitis; and (3) administration of a cyclophosphamide pulse in the ICU or within 48 h before admission to the ICU. The primary endpoint was assessment of mortality rate 90 days after admission to the ICU. RESULTS: Eighty-two patients at 20 centers were included, 94% of whom had a recent (<6 months) diagnosis of small-vessel vasculitis. Forty-four patients (54%) had granulomatosis with polyangiitis. The main reasons for admission were respiratory failure (34%) and pulmonary-renal syndrome (33%). Mechanical ventilation was required in 51% of patients, catecholamines in 31%, and renal replacement therapy in 71%. Overall mortality at 90 days was 18% and the mortality in ICU was 16 %. The main causes of death in the ICU were disease flare in 69% and infection in 31%. In univariable analysis, relevant factors associated with death in nonsurvivors compared with survivors were Simplified Acute Physiology Score II (median [interquartile range] 51 [38-82] vs. 36 [27-42], p = 0.005), age (67 years [62-74] vs. 58 years [40-68], p < 0.003), Sequential Organ Failure Assessment score on the day of cyclophosphamide administration (11 [6-12] vs. 6 [3-7], p = 0.0004), and delayed administration of cyclophosphamide (5 days [3-14] vs. 2 days [1-5], p = 0.0053). CONCLUSIONS: Patients admitted to the ICU for management of acute small-vessel vasculitis benefit from early, aggressive intensive care treatment, associated with an 18% death rate at 90 days.

RESUMEN

Importance: Although frequently used in treating intensive care unit (ICU) patients with sepsis, empirical antifungal therapy, initiated for suspected fungal infection, has not been shown to improve outcome. Objective: To determine whether empirical micafungin reduces invasive fungal infection (IFI)-free survival at day 28. Design, Setting, and Participants: Multicenter double-blind placebo-controlled study of 260 nonneutropenic, nontransplanted, critically ill patients with ICU-acquired sepsis, multiple Candida colonization, multiple organ failure, exposed to broad-spectrum antibacterial agents, and enrolled between July 2012 and February 2015 in 19 French ICUs. Interventions: Empirical treatment with micafungin (100 mg, once daily, for 14 days) (n = 131) vs placebo (n = 129). Main Outcomes and Measures: The primary end point was survival without proven IFI 28 days after randomization. Key secondary end points included new proven fungal infections, survival at day 28 and day 90, organ failure, serum (1-3)-ß-D-glucan level evolution, and incidence of ventilator-associated bacterial pneumonia. Results: Among 260 patients (mean age 63 years; 91 [35%] women), 251 (128, micafungin group; 123, placebo group) were included in the modified intent-to-treat analysis. Median values were 8 for Sequential Organ Failure Assessment (SOFA) score, 3 for number of Candida-colonized sites, and 99 pg/mL for level of (1-3)-ß-D-glucan. On day 28, there were 82 (68%) patients in the micafungin group vs 79 (60.2%) in the placebo group who were alive and IFI free (hazard ratio [HR], 1.35 [95% CI, 0.87-2.08]). Results were similar among patients with a (1-3)-ß-D-glucan level of greater than 80 pg/mL (n = 175; HR, 1.41 [95% CI, 0.85-2.33]). Day-28 IFI-free survival in patients with a high SOFA score (>8) was not significantly different when compared between the micafungin vs placebo groups (HR, 1.69 [95% CI, 0.96-2.94]). Use of empirical micafungin decreased the rate of new invasive fungal infection in 4 of 128 patients (3%) in the micafungin group vs placebo (15/123 patients [12%]) (P = .008). Conclusions and Relevance: Among nonneutropenic critically ill patients with ICU-acquired sepsis, Candida species colonization at multiple sites, and multiple organ failure, empirical treatment with micafungin, compared with placebo, did not increase fungal infection-free survival at day 28.

RESUMEN

BACKGROUND: Characteristics and outcomes of adult patients with disseminated toxoplasmosis admitted to the intensive care unit (ICU) have rarely been described. METHODS: We performed a retrospective study on consecutive adult patients with disseminated toxoplasmosis who were admitted from January 2002 through December 2012 to the ICUs of 14 university-affiliated hospitals in France. Disseminated toxoplasmosis was defined as microbiological or histological evidence of disease affecting >1 organ in immunosuppressed patients. Isolated cases of cerebral toxoplasmosis were excluded. Clinical data on admission and risk factors for 60-day mortality were collected. RESULTS: Thirty-eight patients were identified during the study period. Twenty-two (58%) had received an allogeneic hematopoietic stem cell transplant (median, 61 [interquartile range {IQR}, 43-175] days before ICU admission), 4 (10%) were solid organ transplant recipients, and 10 (27%) were infected with human immunodeficiency virus (median CD4 cell count, 14 [IQR, 6-33] cells/µL). The main indications for ICU admission were acute respiratory failure (89%) and shock (53%). The 60-day mortality rate was 82%. Allogeneic hematopoietic stem cell transplant (hazard ratio [HR] = 2.28; 95% confidence interval [CI], 1.05-5.35; P = .04) and systolic cardiac dysfunction (HR = 3.54; 95% CI, 1.60-8.10; P < .01) within 48 hours of ICU admission were associated with mortality. CONCLUSIONS: Severe disseminated toxoplasmosis leading to ICU admission has a poor prognosis. Recipients of allogeneic hematopoietic stem cell transplant appear to have the highest risk of mortality. We identified systolic cardiac dysfunction as a major determinant of outcome. Strategies aimed at preventing this fatal opportunistic infection may improve outcomes.

RESUMEN

Background: Cardiac arrest is the most life-threatening complication of attempted suicide by hanging. However, data are scarce on its characteristics and outcome predictors. Methods: This retrospective observational multicentre study in 31 hospitals included consecutive adults admitted after cardiac arrest induced by suicidal hanging. Factors associated with in-hospital mortality were identified by multivariate logistic regression with multiple imputations for missing data and adjusted to the temporal trends over the study period. Results: Of 450 patients (350 men, median age, 43 [34-52] years), 305 (68%) had a psychiatric history, and 31 (6.9%) attempted hanging while hospitalized. The median time from unhanging to cardiopulmonary resuscitation was 0 [0-5] min, and the median time to return of spontaneous circulation (ROSC) was 20 [10-30] min. Seventy-nine (18%) patients survived to hospital discharge. Three variables were independently associated with higher in-hospital mortality: time from collapse or unhanging to ROSC>20 min (odds ratio [OR], 4.71; 95% confidence intervals [95%CIs], 2.02-10.96; p = 0.0004); glycaemia >1.4 g/L at admission (OR, 6.38; 95%CI, 2.60-15.66; p < 0.0001); and lactate >3.5 mmol/L at admission (OR, 6.08; 95%CI, 1.71-21.06; p = 0.005). A Glasgow Coma Scale (GCS) score of >5 at admission was associated with lower in-hospital mortality (OR, 0.009; 95%CI, 0.02-0.37; p = 0.0009). Conclusion: In patients with hanging-induced cardiac arrest, time from collapse or unhanging to return of spontaneous circulation, glycaemia, arterial lactate, and coma depth at admission were independently associated with survival to hospital discharge. Knowledge of these risk factors may help guide treatment decisions in these patients at high risk of hospital mortality.

RESUMEN

BACKGROUND: The optimal calorie and protein intakes at the acute phase of severe critical illness remain unknown. We hypothesised that early calorie and protein restriction improved outcomes in these patients, compared with standard calorie and protein targets. METHODS: The pragmatic, randomised, controlled, multicentre, open-label, parallel-group NUTRIREA-3 trial was performed in 61 French intensive care units (ICUs). Adults (≥18 years) receiving invasive mechanical ventilation and vasopressor support for shock were randomly assigned to early nutrition (started within 24 h after intubation) with either low or standard calorie and protein targets (6 kcal/kg per day and 0·2-0·4 g/kg per day protein vs 25 kcal/kg per day and 1·0-1·3 g/kg per day protein) during the first 7 ICU days. The two primary endpoints were time to readiness for ICU discharge and day 90 all-cause mortality. Key secondary outcomes included secondary infections, gastrointestinal events, and liver dysfunction. The trial is registered on ClinicalTrials.gov, NCT03573739, and is completed. FINDINGS: Of 3044 patients randomly assigned between July 5, 2018, and 8 Dec 8, 2020, eight withdrew consent to participation. By day 90, 628 (41·3%) of 1521 patients in the low group and 648 (42·8%) of 1515 patients in the standard group had died (absolute difference -1·5%, 95% CI -5·0 to 2·0; p=0·41). Median time to readiness for ICU discharge was 8·0 days (IQR 5·0-14·0) in the low group and 9·0 days (5·0-17·0) in the standard group (hazard ratio [HR] 1·12, 95% CI 1·02 to 1·22; p=0·015). Proportions of patients with secondary infections did not differ between the groups (HR 0·85, 0·71 to 1·01; p=0·06). The low group had lower proportions of patients with vomiting (HR 0·77, 0·67 to 0·89; p<0·001), diarrhoea (0·83, 0·73 to 0·94; p=0·004), bowel ischaemia (0·50, 0·26 to 0·95; p=0·030), and liver dysfunction (0·92, 0·86-0·99; p=0·032). INTERPRETATION: Compared with standard calorie and protein targets, early calorie and protein restriction did not decrease mortality but was associated with faster recovery and fewer complications.

RESUMEN

UNLABELLED: Study Type--Therapy (case series) Level of Evidence 4. What's known on the subject? and What does the study add? The pathophysiology of post-renal acute kidney injury (PR-AKI), i.e. caused by urinary tract obstruction, has been extensively studied in animal models but clinical studies on this subject are outdated, and/or have focused on the mechanisms of 'post-obstructive diuresis' (POD), a potentially life-threatening polyuria that can develop after the release of obstruction. In severe PR-AKI, the risk of occurrence of POD is high. POD occurrence predicts renal recovery without the persistence of severe chronic kidney failure. In the present study, the occurrence of POD and the persistence of chronic renal sequelae could be predicted early from clinical variables at admission before the release of obstruction. OBJECTIVE: • To identify predictors of post-obstructive diuresis (POD) occurrence or severe chronic renal failure (CRF) persistence after the release of urinary tract obstruction in the setting of post-renal acute kidney injury (PR-AKI). PATIENTS AND METHODS: • Bi-centre retrospective observational study of all patients with PR-AKI treated in two intensive care units (ICUs) from 1998 to 2010. • Clinical, biological and imaging characteristics on admission and after the release of obstruction were analysed with univariate and, if possible, multivariate analysis to search for predictors of (i) occurrence of POD (diuresis >4 L/day) after the release of obstruction; (ii) persistence of severe CRF (estimated glomerular filtration rate <30 mL/min/1.73 m(2), including end-stage CRF) at 3 months. RESULTS: • On admission, median (range) serum creatinine was 866 (247-3119) µmol/L. • POD occurred in 34 (63%) of the 54 analysable patients. On admission, higher serum creatinine (Odds ratio [OR] 1.002 per 1 µmol/L, 95% confidence interval [CI] 1.000-1.004, P = 0.004), higher serum bicarbonate (OR 1.36 per 1 mmol/L, 95% CI 1.13-1.65, P < 0.001), and urinary retention (OR 6.96, 95% CI 1.34-36.23, P = 0.01) independently predicted POD occurrence. • Severe CRF persisted in seven (21%) of the 34 analysable patients, including two (6%) cases of end-stage CRF. Predictors of severe CRF persistence after univariate analysis were: lower blood haemoglobin (P < 0.001) and lower serum bicarbonate (P = 0.03) on admission, longer time from admission to the release of obstruction (P = 0.01) and absence of POD (P = 0.04) after the release of obstruction. CONCLUSIONS: • In severe PR-AKI treated in ICU, POD occurrence was a frequent event that predicted renal recovery without severe CRF. • POD occurrence or severe CRF persistence could be predicted early from clinical and biological variables at admission before the release of obstruction.

RESUMEN

Background: Strong evidence suggests a correlation between pharmacodynamics (PD) index and antibiotic efficacy while dose adjustment should be considered in critically ill patients due to modified pharmacokinetic (PK) parameters and/or higher minimum inhibitory concentrations (MICs). This study aimed to assess pharmacodynamic (PD) target attainment considering both antibiotics serum concentrations and measured MICs in these patients. Method: A multicentric prospective open-label trial conducted in 11 French ICUs involved patients with Gram-negative bacilli (GNB) ventilator-associated pneumonia (VAP) confirmed by quantitative cultures. Results: We included 117 patients. Causative GNBs were P. aeruginosa (40%), Enterobacter spp. (23%), E. coli (20%), and Klebsiella spp. (16%). Hence, 117 (100%) patients received ß-lactams, 65 (58%) aminoglycosides, and two (1.5%) fluoroquinolones. For ß-lactams, 83% of the patients achieved a Cmin/MIC > 1 and 70% had a Cmin/MIC > 4. In the case of high creatinine clearance (CrCL > 100 mL/min/1.73 m2), 70.4% of the patients achieved a Cmin/MIC ratio > 1 versus 91% otherwise (p = 0.041), and 52% achieved a Cmin/MIC ratio > 4 versus 81% (p = 0.018). For aminoglycosides, 94% of the patients had a Cmax/MIC ratio > 8. Neither ß-lactams nor aminoglycosides PK/PD parameters were associated clinical outcomes, but our data suggest a correlation between ß-lactams Cmin/MIC and microbiological success. Conclusion: In our ICU patients treated for GNB VAP, using recommended antibiotic dosage led in most cases to PK/PD targets attainment for aminoglycosides and ß-lactams. High creatinine clearance should encourage clinicians to focus on PK/PD issues.

RESUMEN

PURPOSE: Acute mesenteric ischemia (AMI) is a rare, but life-threatening condition occurring among critically ill patients. Several factors have been associated with AMI, but the causal link is debated, most studies being retrospective. Among these factors, enteral nutrition (EN) could be associated with AMI, in particular among patients with shock. We aimed to study the factors independently associated with AMI in a post hoc analysis of the NUTRIREA-2 trial including 2410 critically ill ventilated patients with shock, randomly assigned to receive EN or parenteral nutrition (PN). METHODS: Post hoc analysis of the NUTRIREA-2 trial was conducted. Ventilated adults with shock were randomly assigned to receive EN or PN. AMI was assessed by computed tomography, endoscopy, or laparotomy. Factors associated with AMI were studied by univariate and multivariate analysis. RESULTS: 2410 patients from 44 French intensive care units (ICUs) were included in the study: 1202 patients in the enteral group and 1208 patients in the parenteral group. The median age was 67 [58-76] years, with 67% men, a SAPS II score of 59 [46-74], and a medical cause for ICU admission in 92.7%. AMI was diagnosed among 24 (1%) patients, mainly by computed tomography (79%) or endoscopy (38%). The mechanism of AMI was non-occlusive mesenteric ischemia (n = 12), occlusive (n = 4), and indeterminate (n = 8). The median duration between inclusion in the trial and AMI diagnosis was 4 [1-11] days. Patients with AMI were older, had a higher SAPS II score at ICU admission, had higher plasma lactate, creatinine, and ASAT concentrations and lower hemoglobin concentration, had more frequently EN, dobutamine, and CVVHDF at inclusion, developed more frequently bacteremia during ICU stay, and had higher 28-day and 90-day mortality rates compared with patients without AMI. By multivariate analysis, AMI was independently associated with EN, dobutamine use, SAPS II score ≥ 62 and hemoglobin concentration ≤ 10.9 g/dL. CONCLUSION: Among critically ill ventilated patients with shock, EN, dobutamine use, SAPS II score ≥ 62 and hemoglobin ≤ 10.9 g/dL were independently associated with AMI. Among critically ill ventilated patients requiring vasopressors, EN should be delayed or introduced cautiously in case of low cardiac output requiring dobutamine and/or in case of multiple organ failure with high SAPS II score.

RESUMEN

INTRODUCTION: Several factors, including diuretic use and sepsis, interfere with the fractional excretion of sodium, which is used to distinguish transient from persistent acute kidney injury (AKI). These factors do not affect the fractional excretion of urea (FeUrea). However, there are conflicting data on the diagnostic accuracy of FeUrea. METHODS: We conducted an observational, prospective, multicenter study at three ICUs in university hospitals. Unselected patients, except those with obstructive AKI, were admitted to the participating ICUs during a six-month period. Transient AKI was defined as AKI caused by renal hypoperfusion and reversal within three days. The results are reported as medians (interquartile ranges). RESULTS: A total of 203 patients were included. According to our definitions, 67 had no AKI, 54 had transient AKI and 82 had persistent AKI. FeUrea was 39% (28 to 40) in the no-AKI group, 41% (29 to 54) in the transient AKI group and 32% (22 to 51) in the persistent AKI group (P = 0.12). FeUrea was of little help in distinguishing transient AKI from persistent AKI, with the area under the receiver operating characteristic curve being 0.59 (95% confidence interval, 0.49 to 0.70; P = 0.06). Sensitivity was 63% and specificity was 54% with a cutoff of 35%. In the subgroup of patients receiving diuretics, the results were similar. CONCLUSIONS: FeUrea may be of little help in distinguishing transient AKI from persistent AKI in critically ill patients, including those receiving diuretic therapy. Additional studies are needed to evaluate alternative markers or strategies to differentiate transient from persistent AKI.

RESUMEN

INTRODUCTION: International guidelines include early nutritional support (≤48 hour after admission), 20-25 kcal/kg/day, and 1.2-2 g/kg/day protein at the acute phase of critical illness. Recent data challenge the appropriateness of providing standard amounts of calories and protein during acute critical illness. Restricting calorie and protein intakes seemed beneficial, suggesting a role for metabolic pathways such as autophagy, a potential key mechanism in safeguarding cellular integrity, notably in the muscle, during critical illness. However, the optimal calorie and protein supply at the acute phase of severe critical illness remains unknown. NUTRIREA-3 will be the first trial to compare standard calorie and protein feeding complying with guidelines to low-calorie low-protein feeding. We hypothesised that nutritional support with calorie and protein restriction during acute critical illness decreased day 90 mortality and/or dependency on intensive care unit (ICU) management in mechanically ventilated patients receiving vasoactive amine therapy for shock, compared with standard calorie and protein targets. METHODS AND ANALYSIS: NUTRIREA-3 is a randomised, controlled, multicentre, open-label trial comparing two parallel groups of patients receiving invasive mechanical ventilation and vasoactive amine therapy for shock and given early nutritional support according to one of two strategies: early calorie-protein restriction (6 kcal/kg/day-0.2-0.4 g/kg/day) or standard calorie-protein targets (25 kcal/kg/day, 1.0-1.3 g/kg/day) at the acute phase defined as the first 7 days in the ICU. We will include 3044 patients in 61 French ICUs. Two primary end-points will be evaluated: day 90 mortality and time to ICU discharge readiness. The trial will be considered positive if significant between-group differences are found for one or both alternative primary endpoints. Secondary outcomes include hospital-acquired infections and nutritional, clinical and functional outcomes. ETHICS AND DISSEMINATION: The NUTRIREA-3 study has been approved by the appropriate ethics committee. Patients are included after informed consent. Results will be submitted for publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT03573739.

RESUMEN

OBJECTIVES: To reassess the prognosis of patients with cirrhosis admitted to the intensive care unit. DESIGN: A retrospective study in a medical intensive care unit in a teaching hospital in France. PATIENTS: All patients with cirrhosis without previous liver transplantation admitted in the period from 2005 to 2008. INTERVENTIONS: None. MAIN RESULTS: One hundred thirty-eight patients were studied. Survival rates in the intensive care unit, in hospital, and at 6 months were 59% (95% confidence interval, 50%-67%), 46% (95% confidence interval, 38%-54%), and 38% (95% confidence interval, 30%-47%), respectively. In-hospital survival rates for patients requiring vasopressors, mechanical ventilation, or renal replacement therapy were 20%, 33%, and 31%, respectively. On day 1, independent risk factors for in-hospital mortality were age, albuminemia, international normalized ratio, and the Sequential Organ Failure Assessment score computed after discarding points for hematologic failure (modified Sequential Organ Failure Assessment score). Liver disease severity, assessed using a clinical classification, did not correlate with in-hospital mortality. In patients still alive after 3 days, the only prognostic factor was the modified Sequential Organ Failure Assessment score computed after 3 days. To predict in-hospital mortality, the modified Sequential Organ Failure Assessment score on day 1 had a greater area under the receiver operating characteristic curve (0.84) than the Simplified Acute Physiology Score II (0.78), the Child-Pugh score (0.76), the model for end-stage liver disease score (0.77), or the model for end-stage liver disease-natremia score (0.75). The in-hospital mortality rate with three or four nonhematologic organ failures on day 1 was not >70%, whereas it was 89% with three nonhematologic organ failures after 3 days spent in the intensive care unit. CONCLUSION: In-hospital survival rate of intensive care unit-admitted cirrhotic patients seemed acceptable, even in patients requiring life-sustaining treatments and/or with multiple organ failure on admission. The most important risk factor for in-hospital mortality was the severity of nonhematologic organ failure, as best assessed after 3 days. A trial of unrestricted intensive care for a few days could be proposed for select critically ill cirrhotic patients.

RESUMEN

BACKGROUND: Near-hanging experiences are life-threatening events about which few data are available. RESEARCH QUESTION: What are the outcomes and early predictors of hospital mortality in critically ill patients who have undergone a near-hanging experience? STUDY DESIGN AND METHODS: Adult patients who were resuscitated successfully after suicidal near-hanging injury admitted to 31 university or university-affiliated ICUs in France and Belgium between 1992 and 2014 were studied retrospectively. Patients were identified by searching the hospital databases for International Statistical Classification of Diseases and Related Health Problems, 9th and 10th revisions, codes and hospital charts for hanging. Logistic multivariate regression was performed to identify factors associated vital and functional outcomes at hospital discharge as the primary end points. Secondary outcomes were evaluation of temporal trends and identification of predictors of hospital mortality. RESULTS: Of the 886 patients (181 women and 705 men; median age, 43 years; interquartile range, 34-52 years), 266 (30.0%) had attempted suicide previously, 600 (67.7%) had a diagnosed mental illness, and 55 (6.2%) attempted hanging while hospitalized. Median time from hanging awareness to unhanging was 0 min (interquartile range [IQR], 0-0; range, 0-82 min). Median Glasgow Coma Scale score was 3 (IQR, 3-5) at ICU admission. Hanging induced cardiac arrest in 450 of 886 patients (50.8%). Overall, 497 of 886 patients (56.1%) were alive at hospital discharge, including 479 of 497 patients (96.4%) with a favorable neurocognitive outcome (defined as a Glasgow Outcome Scale score of 4 or 5). By multivariate analysis, factors associated with hospital mortality were hanging-induced cardiac arrest (OR, 19.50; 95% CI, 7.21-60.90; P < .00001) and findings at ICU admission of glycemia level > 1.4 g/L (OR, 4.34; 95% CI, 1.82-10.81; P = .0007) and of lactate level > 3.5 mmol/L (OR, 9.98; 95% CI, 4.17-25.36; P < .00001). INTERPRETATION: The findings from this large multicenter retrospective cohort emphasize the very high mortality after hanging injury chiefly because of hanging-induced cardiac arrest. However, patients who survive near-hanging experiences achieve excellent neurocognitive recovery. Studies of early neuroprotective strategies for patients who have undergone near-hanging experiences are warranted.

RESUMEN

PURPOSE: Bereavement research has helped to improve end-of-life practices in the ICU. However, few studies have explored bereaved relatives experience of research participation in this context. We aimed to explore the experience of bereaved relatives' participation in the ARREVE study which included three telephone follow-up calls to complete several quantitative tools. METHODS: Volunteer relatives who participated in the 12-month follow-up call completed a questionnaire about research participation that included ten open-ended questions so that respondents could use their own words and thoughts. These open-ended questions were analyzed using qualitative analysis that examines themes within the data. RESULTS: 175/311 relatives completed the questionnaire. Three themes were derived from the thematic analysis: (1) struggling: reactivation of emotional distress associated with the ICU experience and the loss is frequent, specifically during the 1st follow-up call. (2) Resilience: as time goes by, research participation becomes increasingly positive. The calls are a help both in giving meaning to the relatives' experience and in accepting the loss. (3) Recognition: research calls can compensate for the absence of support during bereavement. CONCLUSION: Although some emotional difficulties must be acknowledged, bereavement research is overall associated with benefits, by facilitating emotional adjustments, meaning-making and resilience. Lack of support and social isolation during bereavement are frequent experiences, revealing that support strategies for bereaved relatives should be developed after the loss of a loved one in the ICU.

RESUMEN

Endocytosed membrane components are recycled to the cell surface either directly from early/sorting endosomes or after going through the endocytic recycling compartment (ERC). Studying recycling mechanisms is difficult, in part due to the fact that specific tools to inhibit this process are scarce. In this study, we have characterized a novel widely expressed protein, named Rififylin (Rffl) for RING Finger and FYVE-like domain-containing protein, that, when overexpressed in HeLa cells, induced the condensation of transferrin receptor-, Rab5-, and Rab11-positive recycling tubulovesicular membranes in the perinuclear region. Internalized transferrin was able to access these condensed endosomes but its exit from this compartment was delayed. Using deletion mutants, we show that the carboxy-terminal RING finger of Rffl is dispensable for its action. In contrast, the amino-terminal domain of Rffl, which shows similarities with the phosphatidylinositol-3-phosphate-binding FYVE finger, is critical for the recruitment of Rffl to recycling endocytic membranes and for the inhibition of recycling, albeit in a manner that is independent of PtdIns(3)-kinase activity. Rffl overexpression represents a novel means to inhibit recycling that will help to understand the mechanisms involved in recycling from the ERC to the plasma membrane.

RESUMEN

PURPOSE: The relative merits of immediate extubation versus terminal weaning for mechanical ventilation withdrawal are controversial, particularly regarding the experience of patients and relatives. METHODS: This prospective observational multicentre study (ARREVE) was done in 43 French ICUs to compare terminal weaning and immediate extubation, as chosen by the ICU team. Terminal weaning was a gradual decrease in the amount of ventilatory assistance and immediate extubation was extubation without any previous decrease in ventilatory assistance. The primary outcome was posttraumatic stress symptoms (Impact of Event Scale Revised, IES-R) in relatives 3 months after the death. Secondary outcomes were complicated grief, anxiety, and depression symptoms in relatives; comfort of patients during the dying process; and job strain in staff. RESULTS: We enrolled 212 (85.5%) relatives of 248 patients with terminal weaning and 190 relatives (90.5%) of 210 patients with immediate extubation. Immediate extubation was associated with airway obstruction and a higher mean Behavioural Pain Scale score compared to terminal weaning. In relatives, IES-R scores after 3 months were not significantly different between groups (31.9 ± 18.1 versus 30.5 ± 16.2, respectively; adjusted difference, -1.9; 95% confidence interval, -5.9 to 2.1; p = 0.36); neither were there any differences in complicated grief, anxiety, or depression scores. Assistant nurses had lower job strain scores in the immediate extubation group. CONCLUSIONS: Compared to terminal weaning, immediate extubation was not associated with differences in psychological welfare of relatives when each method constituted standard practice in the ICU where it was applied. Patients had more airway obstruction and gasps with immediate extubation. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT01818895.

RESUMEN

PURPOSE: Over the last two decades, noninvasive ventilation (NIV) has been proposed in various causes of acute respiratory failure (ARF) but some indications are debated. Current trends in NIV use are unknown. METHODS: Comparison of three multicenter prospective audits including all patients receiving mechanical ventilation and conducted in 1997, 2002, and 2011 in francophone countries. RESULTS: Among the 4132 patients enrolled, 2094 (51%) required ventilatory support for ARF and 2038 (49 %) for non-respiratory conditions. Overall NIV use was markedly increased in 2010/11 compared to 1997 and 2002 (37% of mechanically ventilated patients vs. 16% and 28%, P < 0.05). In 2010/11, the use of first-line NIV for ARF had reached a plateau (24% vs. 16% and 23%, P < 0.05) whereas pre-ICU and post-extubation NIV had substantially increased (11% vs. 4% and 11% vs. 7%, respectively, P < 0.05). First-line NIV remained stable in acute-on-chronic RF, continued to increase in cardiogenic pulmonary edema, but decreased in de novo ARF (16% in 2010/11 vs. 23% in 2002, P < 0.05). The NIV success rate increased from 56% in 2002 to 70% in 2010/11 and remained the lowest in de novo ARF. NIV failure in de novo ARF was associated with increased mortality in 2002 but not in 2010/11. Mortality decreased over time, and overall, NIV use was associated with a lower mortality. CONCLUSION: Increases in NIV use and success rate, an overall decrease in mortality, and a decrease of the adverse impact NIV failure has in de novo ARF suggest better patient selection and greater proficiency of staff in administering NIV.
