Multicenter StudyEndothelial Cell-Specific Molecule-1 in Critically Ill Patients With Hematologic Malignancy.
To assess whether serum concentration of endothelial cell-specific molecule-1 (Endocan) at ICU admission is associated with the use of ICU resources and outcomes in critically ill hematology patients. ⋯ Median total endocan concentrations were 4.46 (2.7-7.8) ng/mL. Endocan concentrations were higher in patients who had received chemotherapy before ICU admission (4.7 [2.8-8.1] ng/mL vs. 3.7 [2.5-6.3] ng/mL [p = 0.002]). In patients with acute respiratory failure, endocan levels were increased in patients with drug-induced pulmonary toxicity compared with other etiologies (p = 0.038). Total endocan levels higher than 4.46 ng/mL were associated with a higher cumulative probability of renal replacement therapy requirement (p = 0.006), a higher requirement of mechanical ventilation (p = 0.01) and a higher requirement of vasopressors throughout ICU stay (p < 0.0001). By multivariate analysis, total endocan levels at admission were independently associated with ICU mortality (odds ratios, 1.39; 95% CI, 1.06-1.83; p = 0.018). The predictive value of endocan peptide fragments of 14 kDa in terms of mortality and life-sustaining therapies requirement was inferior to that of total endocan. Endocan levels were higher in critically ill hematology patients compared with healthy subjects (p < 0.0001) but lower than endocan values in critically ill septic patients without hematologic malignancy (p = 0.005) CONCLUSIONS:: Serum concentrations of endocan at admission are associated with the use of ICU resources and mortality in critically ill hematology patients. Studies to risk-stratify patients in the emergency department or in the hematology wards based on endocan concentrations to identify those likely to benefit from early ICU management are warranted.

Multicenter Study Comparative Study Observational StudyOptimal Cerebral Perfusion Pressure in Centers With Different Treatment Protocols.
The three centers in this study have different policies regarding cerebral perfusion pressure targets and use of vasopressors in traumatic brain injury patients. The aim was to determine if the different policies affected the estimation of cerebral perfusion pressure which optimizes the strength of cerebral autoregulation, termed "optimal cerebral perfusion pressure." ⋯ Differences in optimal cerebral perfusion pressure calculation were found between centers due to demographics (age) and treatment (cerebral perfusion pressure targets). These factors should be considered in the design of trials to determine the efficacy of autoregulation-guided treatment.

Randomized Controlled Trial Multicenter StudyPlatelet Drop and Fibrinolytic Shutdown in Patients With Sepsis.
Thrombocytopenia is the most common hemostatic disorder during sepsis and is associated with high mortality. We examined whether fibrinolytic changes precede incident thrombocytopenia and predict outcome in patients with severe sepsis. ⋯ Impaired fibrinolysis, mainly driven by plasminogen activator inhibitor-1 increase and thrombin activatable fibrinolysis inhibitor activation, is an early manifestation of sepsis and may precede the development of thrombocytopenia. Thrombin activatable fibrinolysis inhibitor level, in particular, proved to be an independent predictor of mortality, which may improve risk stratification of patients with severe sepsis.

Multicenter Study Observational StudyIsolated Traumatic Subarachnoid Hemorrhage: An Evaluation of Critical Care Unit Admission Practices and Outcomes From a North American Perspective.
Traumatic subarachnoid hemorrhage is a common radiographic finding associated with traumatic brain injury. The objective of this investigation is to evaluate the association between hospital-level ICU admission practices and clinically important outcomes for patients with isolated traumatic subarachnoid hemorrhage and mild clinical traumatic brain injury. ⋯ Critical care admission for mild traumatic brain injury patients with isolated traumatic subarachnoid hemorrhage is frequent and highly variable despite low probability of requiring neurosurgical intervention. Reevaluation of hospital-level practices may represent an opportunity for resource optimization when managing patients with mild clinical traumatic brain injury and associated isolated traumatic subarachnoid hemorrhage.

Multicenter Study Observational StudyThoracic Epidural Analgesia and Mortality in Acute Pancreatitis: A Multicenter Propensity Analysis.
Recent preclinical and clinical data suggest that thoracic epidural analgesia, a technique primarily aimed at decreasing pain, might exert anti-inflammatory effects, enhance splanchnic and pancreatic blood flow during acute pancreatitis; however, the influence of epidural analgesia on mortality remains under investigated in this setting. This study was therefore designed to assess the impact of epidural analgesia on mortality in ICU patients with acute pancreatitis. ⋯ Among critically ill patients with acute pancreatitis, mortality at 30 days was lower in patients who received epidural analgesia than in comparable patients who did not. These findings support ongoing research on the use of epidural analgesia as a therapeutic intervention in acute pancreatitis.
