PURPOSE: To evaluate the association between the rectus femoris cross-sectional area (RFCSA) and the muscular strength obtained at the bedside in patients forwarded to the intensive care unit (ICU) for severe sepsis and septic shock. METHODS: A prospective cohort study. RFCSA was assessed by ultrasound on the following day of the ICU admission and monitored during hospitalization. The patients performed clinical tests of muscle strength (Medical Research Council (MRC) scale and handgrip dynamometry), when they could understand the verbal commands of the examiners...

Heat stroke, the most serious type of heat illness, refers to the presence of hyperthermia (core temperature >40°C), accompanied by central nervous system dysfunction. The hippocampus is a particularly vulnerable region in the early stage of heat stroke. Increasing evidence suggests that dysregulation of brain iron metabolism is involved in many neurodegenerative diseases. However, whether heat stroke causes dysfunction of iron metabolism, as well as iron-regulatory proteins, in the hippocampus remains unknown...

OBJECTIVE: Programmed death-1 (PD-1)/programmed death ligand-1 (PD-L1) exists in both membrane-bound and soluble forms. In this study, we evaluated the predictive value of soluble PD-1 (sPD-1) for severity and 28-day mortality in patients with severe sepsis and septic shock during the first week in an intensive care unit (ICU). METHODS: In this prospective cohort study, patients were classified into the severe sepsis group or the septic shock group according to the severity of their condition on ICU admission...

Traumatic brain injury-induced acute lung injury (TBI-ALI) is a serious complication of traumatic brain injury (TBI). Our previous clinical study found that high levels of blood glutamate after TBI were closely related to the occurrence and severity of TBI-ALI, while it remains unknown whether a high concentration of blood glutamate directly causes or aggravates TBI-ALI. We found that inhibition of the adenosine A2A receptor (A2AR) after brain injury alleviated the TBI-ALI; however, it is unknown whether lowering blood glutamate levels in combination with inhibiting the A2AR would lead to better effects...

BACKGROUND: Brain death (BD) induces hemodynamic instability with microcirculatory hypoperfusion, leading to increased organ inflammation and dysfunction. This study investigated the effects of 7.5% hypertonic saline solution (HSS) on mesenteric microcirculatory dysfunction and inflammation in a rat model of BD. METHODS: Male Wistar rats were anesthetized and mechanically ventilated. BD was induced by rapidly inflating an intracranial balloon catheter. The rats were randomly divided into: (1)SH, sham-operated rats subjected to trepanation; (2)NS, rats treated with NaCl 0...

INTRODUCTION: Hemorrhagic shock is a major cause of death after trauma. An additional blunt chest trauma independently contributes to mortality upon the development of an acute lung injury (ALI) by aggravating pathophysiological consequences of hemorrhagic shock. The maintenance of hydrogen sulfide availability is known to play an important role during hemorrhage and ALI. We therefore tested the impact of a genetic 3-mercaptopyruvate sulfurtransferase mutation (Δ3-MST) in a resuscitated murine model of traumatic-hemorrhagic shock...

Mortality is higher in septic patients with a history of alcohol use disorder than in septic patients without a history of chronic alcohol usage. We have previously described a model of chronic alcohol ingestion followed by sepsis from cecal ligation and puncture in which alcohol-fed septic mice have higher mortality than water-fed septic mice, associated with altered gut integrity and increased production of TNF and IFNγ by splenic CD4 T cells without alterations in CD8 T cell function. The purpose of this study was to determine whether this represents a common host response to the combination of alcohol and sepsis by creating a new model in which mice with chronic alcohol ingestion were subjected to a different model of sepsis...

BACKGROUND: Thrombelastography (TEG) fibrinolysis shutdown after trauma is associated with increased mortality due to hypercoagulability-associated organ failure. However, a lack of mechanistic data has precluded the development of novel interventions to treat shutdown. OBJECTIVES: To define the pathophysiology of TEG shutdown in severely injured, bleeding patients through secondary analysis of the PROPPR trial. METHODS: Fibrinolysis was characterized in PROPPR subjects using admission TEG lysis at 30 minutes (LY30) or plasmin-antiplasmin (PAP) levels...

Fibrocytes are unique cells with innate and adaptive immune functions, but these mechanisms have not been fully explored. The aim of this study was to explain the mechanism by which adoptive transfer of exogenous fibrocytes improved bacterial clearance and increased sepsis survival. Initial flow cytometry-based, in vitro assays demonstrated phagocytosis by fibrocytes and intracellular bacterial killing was confirmed by direct plating of cell lysates after exposure to live bacteria. Intravenous adoptive transfer of fibrocytes at the time of cecal ligation and puncture (CLP) or two hours after CLP in mice increased survivability...

OBJECTIVE: Infant cardiopulmonary bypass (CPB) increases intestinal permeability leading to endotoxemia. Alkaline phosphatase (AP) reduces endotoxin toxicity in vitro but its effects on endotoxemia in human disease are poorly understood. We assessed the association between serum AP activity and endotoxemia in infants undergoing CPB and determined the effect of ex vivo addition of AP on endotoxemia. METHODS: Prospective cohort study of 62 infants ≤120 days of age undergoing CPB...

BACKGROUND: Current management principles of haemorrhagic shock after trauma emphasize earlier transfusion therapy to prevent dilution of clotting factors and correct coagulopathy. London's air ambulance (LAA) was the first UK civilian pre-hospital service to routinely offer pre-hospital red blood cell (RBC) transfusion (phRTx). We investigated the effect of phRTx on mortality. METHODS: Retrospective trauma database study comparing mortality before-implementation with after-implementation of phRTx in exsanguinating trauma patients...

BACKGROUND: The IL33/ST2 pathway has been implicated in the pathogenesis of different inflammatory diseases. Our aim was to analyze whether plasma levels of biomarkers involved in the IL33/ST2 axis might help to predict mortality in burn patients. METHODS: Single-center prospective observational cohort pilot study performed at the Burns Unit of the Plastic and Reconstructive Surgery Department of the Vall d'Hebron University Hospital (Barcelona). All patients aged ≥18 years old with second or third-degree burns requiring admission to the Burns Unit were considered for inclusion...

BACKGROUND: Ischemic preconditioning (IPC) and remote ischemic preconditioning (RIPC) protect myocardial tissue against subsequent ischemia and reperfusion injury (IRI) and have a high potential to improve patient outcome. The mediators and mechanisms of protection through IPC and RIPC remain largely unknown, but micro-RNAs (miRNAs) are promising candidates. METHODS: Systematic review of Medline and Embase databases for biomedical scientific literature. RESULTS: 26 relevant publications (21 full-text original articles and 5 conference abstracts) were identified, 8 describing cell culture experiments, 14 animal experiments and 4 randomised clinical trials in humans...

Perfluorocarbon emulsions (PFC) are a class of lipid coated micelle slurries wherein the active center of the micelle is a completely halogen/fluorine substituted hydrocarbon capable of dissolving very large quantities of non-polar gases. Due to their unique enhanced solubility for oxygen (O2) and nitrogen (N2) PFCs have been utilized in research as enhanced gas transport media for situations wherein the microcirculation is dysfunctional. In the early 1990's a PFC emulsion was approved for human use during coronary artery angioplasty and one is presently in use in Russia as well as other countries...

INTRODUCTION: Severe trauma is accompanied by endothelial glycocalyx disruption, which drives coagulopathy, increasing transfusion requirements and death. This syndrome has been termed traumatic endotheliopathy (EOT). Some have suggested EOT results from endothelial cellular damage and apoptosis. Endothelial microvesicles (EMVs) represent cellular damage. We hypothesized that EOT is associated with endothelial damage and apoptosis resulting in an increase in circulating EMVs. METHODS: Prospective, observational study enrolling severely injured patients...

Major burns elicit an acute inflammatory response including various inflammatory cytokines. Cytokines play mutual interacting roles in inflammatory diseases. There is little evidence of the clinical significance of the cytokine network in patients with major burns. This study aimed to investigate the clinical significance of the cytokine network in patients with major burn. This prospective observational study comprising 38 patients with major burns (total body surface area (%TBSA) ≥ 20%) and 12 healthy controls was conducted from April 2014 to December 2016...

Sepsis is a dynamic disease, displaying an inflammatory profile that varies over time and for each organ. Controlling the inflammatory response based in targeting a single molecule has been proved useless. We hypothesized that treatment with bone marrow derived mononuclear cells (BMDMC) may be more efficient to modulate the systemic inflammatory response to infection. Adult male Balb/c mice were subjected to cecal ligation and puncture (CLP) or endotoxemia model of experimental sepsis. BMDMC were separated under Ficoll gradient and injected intravenously 1 hour after the procedures...

Acute brain dysfunction is a complication of sepsis and its pathophysiology remains poorly understood. We studied the brain metabolism in a resuscitated animal model of sepsis. Twelve anesthetized, mechanically ventilated and invasively monitored pigs were allocated to a sham procedure (N = 5) or sepsis (N = 7). Sepsis was induced through fecal inoculation in the peritoneum. Fluid resuscitation was maintained during the entire study period. Animals were observed until spontaneous death or for a maximum of 24 hours...
