Receptor interacting protein kinase 1 (RIPK1) has important kinase-dependent and kinase-independent scaffolding functions that activate or prevent apoptosis or necroptosis in a cell context-dependent manner. The kinase activity of RIPK1 mediates hypothermia and lethality in a mouse model of TNF-induced shock, reflecting the hyperinflammatory state of systemic inflammatory response syndrome (SIRS), where the proinflammatory "cytokine storm" has long been viewed as detrimental. Here, we demonstrate that cytokine and chemokine levels did not predict survival and, importantly, that kinase-inactive Ripk1D138N/D138N hematopoietic cells afforded little protection from TNF- or TNF/zVAD-induced shock in reconstituted mice...

BACKGROUND: Graft preservation continues to be one of the main pillars of pancreas transplantation (PT). Surgical complications, possibly caused or facilitated by organ damage during preservation, continue to occur more frequently after PT than for any other abdominal organ. During the past few years, the Georges Lopez Institute preservation solution IGL-1 has been introduced with satisfactory results for the perfusion and cold storage of abdominal grafts such as kidney and liver. METHODS: Aspects related to 47 PTs with the use of IGL-1 as the only preservation solution performed from January 2012 to September 2017 at Hospital Santa Isabel, Blumenau, Brazil, were retrospectively analyzed...

BACKGROUND: Serum lactate is frequently tested in the emergency department (ED) setting to diagnose visceral ischemia and as a marker of end-organ perfusion. It is highly nonspecific, and levels can be affected by both kidney and liver function. In this retrospective chart review, we aim to demonstrate that serum lactate is overused in the ED setting and predicts resource utilization but not the need for surgical intervention. METHODS: ED records with a chief complaint of "abdominal pain" were queried for the preceding 12 mo...

Sepsis is known since the time (470 BC) of great Greek physician, Hippocrates. Advancement in modern medicine and establishment of separate branches of medical science dealing with sepsis research have improved its outcome. However, mortality associated with sepsis still remains higher (25-30%) that further increases to 40-50% in the presence of septic shock. For example, sepsis-associated deaths account more in comparison to deaths-associated with myocardial-infarction and certain cancers (i.e. breast and colorectal cancer)...

Hyperammonemia is a rare and important complication post-liver transplantation. We review a case of a 5-month-old boy with biliary atresia who received a split liver transplant following a variceal bleed. The transplant was complicated by recurrent portal vein thrombosis. Colonized with Serratia marcescens pretransplant, he developed disseminated infection associated with very high levels of ammonia that led to his death. It is important to be aware of serum ammonia levels in patients with portal vein thrombosis, particularly in the setting of gastrointestinal bleeding and sepsis...

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...

Graft-versus-host-disease after orthotopic liver transplant is a rare and life-threatening complication. The diagnosis is challenging and usually confirmed by chimerism and skin biopsies. The most common cause of death is sepsis (60%), and broad-spectrum antibiotics and antifungal prophylaxis are strongly recommended. We present a case of a 61-year-old man with hepatocellular carcinoma and a previous history of metabolic and alcoholic cirrhosis who underwent orthotopic liver transplant. The immunosuppression regimen consisted of corticosteroids, calcineurin inhibitor, and mammalian target of rapamycin complex 1 inhibitor...

Sepsis is a severe multisystem disease with high mortality rates and limited treatment options. However, advances during the last decade have opened opportunities to develop novel therapeutic strategies. The Notch signaling pathway plays a critical role in inflammation, and its inhibition offers an avenue to treat inflammatory diseases, such as sepsis. Asiatic acid (AA), a triterpenoid isolated from Centella asiatica, reportedly exerts anti-oxidant, anti-tumor, and anti-inflammatory effects, but its mechanisms remain unclear...

Background: The liver is a vital target for sepsis-related injury, leading to inflammatory pathogenesis, multiple organ dysfunction and high mortality rates. Monocyte-derived macrophage transformations are key events in hepatic inflammation. N1 -[(4-methoxy)methyl]-4-methyl-1,2-benzenediamine (FC-99) previously displayed therapeutic potential on experimental sepsis. However, the underlying mechanism of this protective effect is still not clear. Results: FC-99 treatment attenuated the liver dysfunction in septic mice that was accompanied with reduced numbers of pro-inflammatory Ly6Chi monocytes in the peripheral blood and CD11b+ F4/80lo monocyte-derived macrophages in the liver...

Microvascular dysfunction leads to multi-organ failure and mortality in sepsis. Our previous studies demonstrated that administration of exogenous endothelial progenitor cells (EPCs) confers protection in sepsis as evidenced by reduced vascular leakage, improved organ function, and increased survival. We hypothesize that EPCs protect the microvasculature through the exosomes-mediated transfer of microRNAs (miRNAs). Mice were rendered septic by cecal ligation and puncture (CLP), and EPC exosomes were administered intravenously at 4 hr after CLP...

Despite continuous progress in medicine, sepsis remains the main cause of deaths in the intensive care unit. Liver failure complicating sepsis/septic shock has a significant impact on mortality in this group of patients. The pathophysiology of sepsis-associated liver dysfunction is very complicated and still not well understood. According to the Surviving Sepsis Campaign (SSC) Guidelines, the diagnosis of liver dysfunction during sepsis is based on the increase in bilirubin concentration >2 mg/dL and the occurrence of coagulation disorders with INR > 1...

OBJECTIVE: Outcome reporting heterogeneity impedes identification of gold standard treatments for children born with gastroschisis. Use of core outcome sets (COSs) in research reduces outcome reporting heterogeneity and ensures that studies are relevant to patients. The aim of this study was to develop a gastroschisis COS. DESIGN AND SETTING: Systematic reviews and stakeholder nomination were used to identify candidate outcomes that were subsequently prioritised by key stakeholders in a three-phase online Delphi process and face-to-face consensus meeting using a 9-point Likert scale...
