- Abstract
Purpose: Management of acetaminophen overdose focuses on the risk hepatic failure. However, acute renal failure, although less frequent, can lead to serious metabolic complications and require hemodialysis. We report three cases of acute renal failure related to acetaminophen overdose.Clinical Features: Three patients, aged 17-46 yr ingested acetaminophen 19 to 32 g, and were admitted to the intensive care unit because of acute liver failure without hepatic coma. While liver function improved, each patient developed acute renal failure starting on the fourth day. Four sessions of hemodialysis were required in one patient because of anuria. Hepatic function improved from the fourth to the ninth day in each case, whereas renal function recovered later, 10-20 days after ingestion. Investigations were negative for other causes of renal failure, and acute tubular necrosis due to acetaminophen was suspected.Conclusion: The pathophysiology of this type of acute tubular necrosis remains unclear and thus, there is no specific treatment. Nevertheless, in all cases of acetaminophen overdose, we suggest following serum creatinine levels during the first week, regardless of the degree hepatic failure or quantity of acetaminophen ingested.

- Abstract
Sepsis-acquired immunosuppression may play a major role in patients' prognosis through increased risk of secondary infections. Triggering receptor expressed on myeloid cells 1 (TREM-1) is an innate immune receptor involved in cellular activation. Its soluble form (sTREM-1) has been described as a robust marker of mortality in sepsis. The objective of this study was to evaluate its association with the occurrence of nosocomial infections alone or in combination with human leucocyte antigen-DR on monocytes (mHLA-DR)., Design: Observational study., Setting: University Hospital in France., Patients: One hundred sixteen adult septic shock patients as a post hoc study from the IMMUNOSEPSIS cohort (NCT04067674)., Interventions: None., Measurements and Main Results: Plasma sTREM-1 and monocyte HLA-DR were measured at day 1 or 2 (D1/D2), D3/D4, and D6/D8 after admission. Associations with nosocomial infection were evaluated through multivariable analyses. At D6/D8, both markers were combined, and association with increased risk of nosocomial infection was evaluated in the subgroup of patients with most deregulated markers in a multivariable analysis with death as a competing risk. Significantly decreased mHLA-DR at D6/D8 and increased sTREM-1 concentrations were measured at all time points in nonsurvivors compared with survivors. Decreased mHLA-DR at D6/D8 was significantly associated with increased risk of secondary infections after adjustment for clinical parameters with a subdistribution hazard ratio of 3.61 (95% CI, 1.39-9.34; p = 0.008). At D6/D8, patients with persistently high sTREM-1 and decreased mHLA-DR presented with a significantly increased risk of infection (60%) compared with other patients (15.7%). This association remained significant in the multivariable model (subdistribution hazard ratio [95% CI], 4.65 [1.98-10.9]; p < 0.001)., Conclusions: In addition to its prognostic interest on mortality, sTREM-1, when combined with mHLA-DR, may help to better identify immunosuppressed patients at risk of nosocomial infections., Competing Interests: Drs. Derive and Jolly are employed by Inotrem. The remaining authors have disclosed that they do not have any potential conflicts of interest., (Copyright © 2023 The Authors.

- Abstract
Background: Haemodynamically unstable patients often require arterial and venous catheter insertion urgently. We hypothesised that ultrasound-guided arterial and venous catheterisation would reduce mechanical complications., Methods: We performed a prospective RCT, where patients requiring both urgent arterial and venous femoral catheterisation were randomised to either ultrasound-guided or landmark-guided catheterisation. Complications and characteristics of catheter insertion (procedure duration, number of punctures, and procedure success) were recorded at the time of insertion (immediate complications). Late complications were investigated by ultrasound examination performed between the third and seventh days after randomisation. Primary outcome was the proportion of patients with at least one mechanical complication (immediate or late), by intention-to-treat analysis. Secondary outcomes included success rate, procedure time, and number of punctures., Results: We analysed 136 subjects (102 [75%] male; age range: 27-62 yr) by intention to treat. The proportion of subjects with one or more complications was lower in 22/67 (33%) subjects undergoing ultrasound-guided catheterisation compared with landmark-guided catheterisation (40/69 [58%]; odds ratio: 0.35 [95% confidence interval: 0.18-0.71]; P=0.003). Ultrasound-guided catheterisation reduced both immediate (27%, compared with 51% in the landmark approach group; P=0.004) and late (10%, compared with 23% in the landmark approach group; P=0.047) complications. Ultrasound guidance also reduced the proportion of patients who developed deep vein thrombosis (4%, compared with 22% following landmark approach; P=0.012), and achieved a higher procedural success rate (96% vs 78%; P=0.004)., Conclusions: An ultrasound-guided approach reduced mechanical complications after urgent femoral arterial and venous catheterisation, while increasing procedural success., Clinical Trial Registration: NCT02820909., (Copyright © 2021 British Journal of Anaesthesia.

- Abstract
Introduction: Enterococcus species are associated with an increased morbidity in intraabdominal infections (IAI). However, their impact on mortality remains uncertain. Moreover, the influence on outcome of the appropriate or inappropriate status of initial antimicrobial therapy (IAT) is subjected to debate, except in septic shock. The aim of our study was to evaluate whether an IAT that did not cover Enterococcus spp. was associated with 30-day mortality in ICU patients presenting with IAI growing with Enterococcus spp., Material and Methods: Retrospective analysis of French database OutcomeRea from 1997 to 2016. We included all patients with IAI with a peritoneal sample growing with Enterococcus. Primary endpoint was 30-day mortality., Results: Of the 1017 patients with IAI, 76 (8%) patients were included. Thirty-day mortality in patients with inadequate IAT against Enterococcus was higher (7/18 (39%) vs 10/58 (17%), p = 0.05); however, the incidence of postoperative complications was similar. Presence of Enterococcus spp. other than E. faecalis alone was associated with a significantly higher mortality, even greater when IAT was inadequate. Main risk factors for having an Enterococcus other than E. faecalis alone were as follows: SAPS score on day 0, ICU-acquired IAI, and antimicrobial therapy within 3 months prior to IAI especially with third-generation cephalosporins. Univariate analysis found a higher hazard ratio of death with an Enterococcus other than E. faecalis alone that had an inadequate IAT (HR = 4.4 [1.3-15.3], p = 0.019) versus an adequate IAT (HR = 3.1 [1.0-10.0], p = 0.053). However, after adjusting for confounders (i.e., SAPS II and septic shock at IAI diagnosis, ICU-acquired peritonitis, and adequacy of IAT for other germs), the impact of the adequacy of IAT was no longer significant in multivariate analysis. Septic shock at diagnosis and ICU-acquired IAI were prognostic factors., Conclusion: An IAT which does not cover Enterococcus is associated with an increased 30-day mortality in ICU patients presenting with an IAI growing with Enterococcus, especially when it is not an E. faecalis alone. It seems reasonable to use an IAT active against Enterococcus in severe postoperative ICU-acquired IAI, especially when a third-generation cephalosporin has been used within 3 months.

- Abstract
Background: Biliary leak following severe blunt liver injuries is a complex problem becoming more frequent with improvements in non-operative management. Standard treatment requires main bile duct drainage usually performed by endoscopic sphincterotomy and stent placement. We report our experience with cholecystostomy as a first minimally invasive diagnostic and therapeutic approach., Methods: We performed a retrospective analysis of consecutive patients with post-traumatic biliary leak between 2006 and 2015. In the first period (2006-2010), biliary fistula was managed using perihepatic drainage and endoscopic, percutaneous or surgical main bile duct drainage. After 2010, cholecystostomy as an initial minimally invasive approach was performed., Results: Of 341 patients with blunt liver injury, 18 had a post-traumatic biliary leak. Ten patients received standard treatment and eight patients underwent cholecystostomy. The cholecystostomy (62.5%) and the standard treatment (80%) groups presented similar success rates as the first biliary drainage procedure (p = 0.41). Cholecystostomy presented no severe complications and resulted, when successful, in a bile flow rate inversion between the perihepatic drains and the gallbladder drain within a median [IQR] 4 days [1-7]. The median time for bile leak resolution was 26 days in the cholecystostomy group and 39 days in the standard treatment group (p = 0.09). No significant difference was found considering median duration of hospital stay (54 and 74 days, respectively, p = 0.37) or resuscitation stay (17.5 and 19.5 days, p = 0.59)., Conclusion: Cholecystostomy in non-operative management of biliary fistula after blunt liver injury could be an effective, simple and safe first-line procedure in the diagnostic and therapeutic approach of post-traumatic biliary tract injuries.

- Abstract
Importance: It has not been established whether noninvasive ventilation (NIV) reduces the need for invasive mechanical ventilation in patients who develop hypoxemic acute respiratory failure after abdominal surgery., Objective: To evaluate whether noninvasive ventilation improves outcomes among patients developing hypoxemic acute respiratory failure after abdominal surgery., Design, Setting, and Participants: Multicenter, randomized, parallel-group clinical trial conducted between May 2013 and September 2014 in 20 French intensive care units among 293 patients who had undergone abdominal surgery and developed hypoxemic respiratory failure (partial oxygen pressure <60 mm Hg or oxygen saturation [SpO2] ≤90% when breathing room air or <80 mm Hg when breathing 15 L/min of oxygen, plus either [1] a respiratory rate above 30/min or [2] clinical signs suggestive of intense respiratory muscle work and/or labored breathing) if it occurred within 7 days after surgical procedure., Interventions: Patients were randomly assigned to receive standard oxygen therapy (up to 15 L/min to maintain SpO2 of 94% or higher) (n = 145) or NIV delivered via facial mask (inspiratory pressure support level, 5-15 cm H2O; positive end-expiratory pressure, 5-10 cm H2O; fraction of inspired oxygen titrated to maintain SpO2 ≥94%) (n = 148)., Main Outcomes and Measures: The primary outcome was tracheal reintubation for any cause within 7 days of randomization. Secondary outcomes were gas exchange, invasive ventilation-free days at day 30, health care-associated infections, and 90-day mortality., Results: Among the 293 patients (mean age, 63.4 [SD, 13.8] years; n=224 men) included in the intention-to-treat analysis, reintubation occurred in 49 of 148 (33.1%) in the NIV group and in 66 of 145 (45.5%) in the standard oxygen therapy group within+ 7 days after randomization (absolute difference, -12.4%; 95% CI, -23.5% to -1.3%; P = .03). Noninvasive ventilation was associated with significantly more invasive ventilation-free days compared with standard oxygen therapy (25.4 vs 23.2 days; absolute difference, -2.2 days; 95% CI, -0.1 to 4.6 days; P = .04), while fewer patients developed health care-associated infections (43/137 [31.4%] vs 63/128 [49.2%]; absolute difference, -17.8%; 95% CI, -30.2% to -5.4%; P = .003). At 90 days, 22 of 148 patients (14.9%) in the NIV group and 31 of 144 (21.5%) in the standard oxygen therapy group had died (absolute difference, -6.5%; 95% CI, -16.0% to 3.0%; P = .15). There were no significant differences in gas exchange., Conclusions and Relevance: Among patients with hypoxemic respiratory failure following abdominal surgery, use of NIV compared with standard oxygen therapy reduced the risk of tracheal reintubation within 7 days. These findings support use of NIV in this setting., Trial Registration: clinicaltrials.gov Identifier: NCT01971892.

- Abstract
Background: In the intensive care unit (ICU), the outcomes of patients with acute mesenteric ischemia (AMI) are poorly documented. This study aimed to determine the risk factors for death in ICU patients with AMI., Methods: A retrospective, observational, non-interventional, multicenter study was conducted in 43 ICUs of 38 public institutions in France. From January 2008 to December 2013, all adult patients with a diagnosis of AMI during their hospitalization in ICU were included in a database. The diagnosis was confirmed by at least one of three procedures (computed tomography scan, gastrointestinal endoscopy, or upon surgery). To determine factors associated with ICU death, we established a logistic regression model. Recursive partitioning analysis was applied to construct a decision tree regarding risk factors and their interactions most critical to determining outcomes., Results: The death rate of the 780 included patients was 58 %. Being older, having a higher sequential organ failure assessment (SOFA) severity score at diagnosis, and a plasma lactate concentration over 2.7 mmol/l at diagnosis were independent risk factors of ICU mortality. In contrast, having a prior history of peripheral vascular disease or an initial surgical treatment were independent protective factors against ICU mortality. Using age and SOFA severity score, we established an ICU mortality score at diagnosis based on the cutoffs provided by recursive partitioning analysis. Probability of survival was statistically different (p < 0.001) between patients with a score from 0 to 2 and those with a score of 3 and 4., Conclusion: Acute mesenteric ischemia in ICU patients was associated with a 58 % ICU death rate. Age and SOFA severity score at diagnosis were risk factors for mortality. Plasma lactate concentration over 2.7 mmol/l was also an independent risk factor, but values in the normal range did not exclude the diagnosis of AMI.

- Abstract
Introduction: The use of vegetable beverages improperly called « vegetable milk » is promoted by food faddism to replace dairy products, even in infant diet whereas it is totally inadequate., Case Reports: Case 1: a 9 month-old infant fed by a rice beverage for 2 months presented hypoalbuminemia (7 g/L) with kwashiorkor syndrome complicated by severe sepsis. Case 2: a 14 month-old infant fed by a rice beverage for 2 months had iron and vitamin B12 deficiency with deep anemia (Hb 35 g/L) and tissue hypoxia (hyperlactacidemia). Case 3: a 13 month-old infant fed by an almond beverage during 3 weeks presented metabolic alkalosis with hypochloremia due to sodium and chloride deficiency and revealed by hypoventilation. Case 4: a 2,5 month-old infant with epileptic encephalopathy was fed by several vegetable beverages (almond, nut, chestnut and soy) for a month and a half and presented deep hyponatremia (96 mmol/L) with coma and respiratory acidosis caused by aspiration pneumonia. He died secondarily., Discussion: Deficiencies promote infections and severe metabolic disorders. Clinical polymorphism lead to diagnosis wandering that can be noxious. The reasons of these diet changes can be nutritional ignorance, perceived milk intolerance or food faddism, sometimes on the advice of an alternative medicine physician. Parental restricted diet or infant immunization recommendations negligence should warn about associated nutritional errors in young infants., Conclusion: These avoidable pathologies frequently caused by well-intending but misinformed parents must be reported to Nutrivigilance. This behaviour can be life threatening and must lead, in the most severe cases, to prosecution., (Copyright © 2012 Elsevier Masson SAS. All rights reserved.)

- Abstract
Background: To assess preload dependence, the variation of the plethysmographic waveform of pulse oximetry (ΔPOP) has been proposed as a surrogate of the pulse pressure variation (ΔPP). The aim of the study was to assess the ability of the pulse oximeter-derived plethysmographic analysis to accurately trend ΔPP in patients undergoing major abdominal surgery by using standard monitors., Methods: A continuous recording of arterial and plethysmographic waveform was performed in 43 patients undergoing abdominal surgery. ΔPP and ΔPOP were calculated on validated respiratory cycles., Results: For analysis, 92,467 respiratory cycles were kept (73.5% of cycles recorded in 40 patients). The mean of intrapatient coefficients of correlation was low (r = 0.22). The Bland and Altman analysis showed a systematic bias of 5.21; the ΔPOP being greater than the ΔPP, this bias increased with the mean value of the two indices and the limits of agreement were wide (upper 21.7% and lower -11.3%). Considering a ΔPP threshold at 12% to classify respiratory cycles as responders and nonresponders, the corresponding best cutoff value of ΔPOP was 13.6 ± 4.3%. Using these threshold values, the observed classification agreement was moderate (κ = 0.50 ± 0.09)., Conclusions: The wide limits of agreement between ΔPP and ΔPOP and the weak correlation between both values cast doubt regarding the ability of ΔPOP to substitute ΔPP to follow trend in preload dependence and classify respiratory cycles as responders or nonresponders using standard monitor during anesthesia for major abdominal surgery.

- Abstract
Purpose: Management of acetaminophen overdose focuses on the risk hepatic failure. However, acute renal failure, although less frequent, can lead to serious metabolic complications and require hemodialysis. We report three cases of acute renal failure related to acetaminophen overdose., Clinical Features: Three patients, aged 17-46 yr ingested acetaminophen 19 to 32 g, and were admitted to the intensive care unit because of acute liver failure without hepatic coma. While liver function improved, each patient developed acute renal failure starting on the fourth day. Four sessions of hemodialysis were required in one patient because of anuria. Hepatic function improved from the fourth to the ninth day in each case, whereas renal function recovered later, 10-20 days after ingestion. Investigations were negative for other causes of renal failure, and acute tubular necrosis due to acetaminophen was suspected., Conclusion: The pathophysiology of this type of acute tubular necrosis remains unclear and thus, there is no specific treatment. Nevertheless, in all cases of acetaminophen overdose, we suggest following serum creatinine levels during the first week, regardless of the degree hepatic failure or quantity of acetaminophen ingested.

- Abstract
1. Experiments were conducted in chronically prepared dogs to determine if gradual obstruction of the proximal femoral arteries would also cause collateralization in the coronary circulation. 2. Peripheral coronary pressure was measured before and after peripheral collateralization as an index of coronary collateral function. Coronary collateral blood flow was measured with radioactive microspheres after peripheral collateralization. 3. Peripheral coronary pressure was not significantly altered by peripheral collateralization. Coronary collateral blood flow measured after peripheral collateralization was similar to that reported in non-collateralized hearts. 4. Results indicated that the mechanism(s) responsible for peripheral collateralization do not act systemically, at least not on the coronary circulation.
