Interleukin-10: A Potential Pre-Cannulation Marker for Development of Acute Kidney Injury in Patients Receiving Veno-Arterial Extracorporeal Membrane Oxygenation.

Introduction: Acute kidney injury (AKI) in patients treated with veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is associated with high mortality. The objective of this study was to investigate whether cytokine levels before the initiation of ECMO treatment could predict AKI. We also aimed to investigate the impact of AKI on 30-day and 1-year mortality.

Carbon dioxide flooding to reduce postoperative neurological injury following surgery for acute type A aortic dissection: a prospective, randomised, blinded, controlled clinical trial, CARTA study protocol - objectives and design.

Introduction: Neurological complications after surgery for acute type A aortic dissection (ATAAD) increase patient morbidity and mortality. Carbon dioxide flooding is commonly used in open-heart surgery to reduce the risk of air embolism and neurological impairment, but it has not been evaluated in the setting of ATAAD surgery. This report describes the objectives and design of the CARTA trial, investigating whether carbon dioxide flooding reduces neurological injury following surgery for ATAAD.

Reduced renal elimination of larger molecules is a strong predictor for mortality.

Renal dysfunction is a major risk factor for premature death and has been studied extensively. A new renal syndrome, shrunken pore syndrome (SPS), confers higher mortality in all studied populations. SPS is a condition in which cystatin C-based estimation of glomerular filtration rate (eGFR) is ≥ 60% than creatinine-based estimation of glomerular filtration rate (eGFR).

Effect of Cyclosporine on Cytokine Production in Elective Coronary Artery Bypass Grafting: A Sub-Analysis of the CiPRICS (Cyclosporine to Protect Renal Function in Cardiac Surgery) Study.

Objectives: The augmented inflammatory response to cardiac surgery is a recognized cause of postoperative acute kidney injury. The present study aimed to investigate the effects of preoperative cyclosporine treatment on cytokine production and delineate factors associated with postoperative kidney impairment.

Design: A randomized, double-blind, placebo-controlled, single-center study.

Lung transplant after 6 months on ECMO support for SARS-CoV-2-induced ARDS complicated by severe antibody-mediated rejection.

There have been a few reports of successful lung transplantation (LTx) in patients with SARS-CoV-2-induced acute respiratory distress syndrome (ARDS); however, all reports were with rather short follow-up. Here we present a 62-year-old man without prior lung diseases. Following SARS-CoV-2-induced ARDS and 6 months of extracorporeal membrane oxygenation, he underwent LTx.

Monitoring lung injury with particle flow rate in LPS- and COVID-19-induced ARDS.

In severe acute respiratory distress syndrome (ARDS), extracorporeal membrane oxygenation (ECMO) is a life-prolonging treatment, especially among COVID-19 patients. Evaluation of lung injury progression is challenging with current techniques. Diagnostic imaging or invasive diagnostics are risky given the difficulties of intra-hospital transportation, contraindication of biopsies, and the potential for the spread of infections, such as in COVID-19 patients.

The mortality increase in cardiac surgery patients associated with shrunken pore syndrome correlates with the eGFR/eGFR-ratio.

Shrunken pore syndrome (SPS) is a condition in which estimated glomerular filtration rate (eGFR) based upon cystatin C is lower than eGFR based upon creatinine. It has been associated with increased mortality even in the presence of normal GFR in both a cardiac surgical population and a general population. No systematic studies of the variation in eGFR/eGFR-ratio used for SPS diagnosis have been published.

Cyclosporine before Coronary Artery Bypass Grafting Does Not Prevent Postoperative Decreases in Renal Function: A Randomized Clinical Trial.

Background: Acute kidney injury is a common complication after cardiac surgery, leading to increased morbidity and mortality. One suggested cause for acute kidney injury is extracorporeal circulation-induced ischemia-reperfusion injury. In animal studies, cyclosporine has been shown to reduce ischemia-reperfusion injury in the kidneys.

Ciclosporin to Protect Renal function In Cardiac Surgery (CiPRICS): a study protocol for a double-blind, randomised, placebo-controlled, proof-of-concept study.

Introduction: Acute kidney injury (AKI) after cardiac surgery is common and results in increased morbidity and mortality. One possible mechanism for AKI is ischaemia-reperfusion injury caused by the extracorporeal circulation (ECC), resulting in an opening of the mitochondrial permeability transition pore (mPTP) in the kidneys, which can lead to cell injury or cell death. Ciclosporin may block the opening of mPTP if administered before the ischaemia-reperfusion injury.

The predictive value of s-cystatin C for mortality after coronary artery bypass surgery.

Objectives: To evaluate serum creatinine (s-creatinine) and serum cystatin C (s-cystatin C) levels and estimated glomerular filtration rate (eGFR) at different time points as predictors for mortality in patients undergoing coronary artery bypass grafting (CABG).

Methods: A total of 1638 patients undergoing elective CABG were studied prospectively over a median follow-up of 3.5 years (range, 2.

Transfusion of sex-mismatched and non-leukocyte-depleted red blood cells in cardiac surgery increases mortality.

Objective: To examine the mortality risk of blood transfusions when donor information, postdonation treatment, and a wide selection of risk factors are taken into account.

Methods: A retrospective study was performed on 9907 patients who underwent coronary artery bypass grafting and/or aortic valve replacement. Several transfusion-related risk factors, including age of blood products, sex of donor, ABO group, Rh group, posttransfusion treatment, and sex matching, were included in the analysis.

Erythropoietin and protection of renal function in cardiac surgery (the EPRICS Trial).

Background: To date, there are no known methods for preventing acute kidney injury after cardiac surgery. Increasing evidence suggests that erythropoietin has renal antiapoptotic and tissue protective effects. However, recent human studies have shown conflicting results.

Incidence, dynamics, and prognostic value of acute kidney injury for death after cardiac surgery.

Objective: This study relates long-term mortality after cardiac surgery to different methods of measuring postoperative renal function, classified according to the Risk, Injury, Failure, Loss, and End-stage (RIFLE) criteria. The dynamics of acute kidney injury during hospital stay were studied by comparing renal function preoperatively, at its poorest measurement, and at discharge.

Methods: A total of 5746 patients undergoing coronary artery bypass grafting were studied in a Cox analysis, over a median follow-up time of 6.

Risks associated with the transfusion of various blood products in aortic valve replacement.

Background: Patients undergoing cardiac operations often require transfusions of red blood cells, plasma, and platelets. From a statistical point of view, there is a significant collinearity between the components, but they differ in indications for use and composition. This study explores the relationship between the transfusion of different blood components and long-term mortality in patients undergoing aortic valve replacement alone or combined with revascularization.

Increased long-term mortality with plasma transfusion after coronary artery bypass surgery.

Purpose: Patients undergoing cardiac surgery often require transfusions of red blood cells, plasma and platelets. These components differ widely in both indications for use and composition. However, from a statistical point of view there is a significant colinearity between the components.

S100B profiles and cognitive function at high altitude.

Exposure to high altitude can lead to acute mountain sickness (AMS) and high altitude cerebral edema (HACE). In this study we investigated the effect of high altitude on neurocognitive function and S100B release. Increased S100B release has been hypothesized to signify a loss of integrity in the blood-brain barrier (BBB).

Blood-brain barrier transport of morphine in patients with severe brain trauma.

Aims: In experimental studies, morphine pharmacokinetics is different in the brain compared with other tissues due to the properties of the blood-brain barrier, including action of efflux pumps. It was hypothesized in this clinical study that active efflux of morphine occurs also in human brain, and that brain injury would alter cerebral morphine pharmacokinetics.

Methods: Patients with traumatic brain injury, equipped with one to three microdialysis catheters in the brain and one in abdominal subcutaneous fat for metabolic monitoring, were studied.

Experimental pancreatitis causes acute perturbation of energy metabolism in the intestinal wall.

Introduction: The systemic inflammatory response syndrome (SIRS) may be initiated by a number of underlying conditions such as acute pancreatitis. The association between the local inflammatory reaction, the systemic response, and potential concomitant dysfunction of remote organs is not quite clear.

Aim: To evaluate whether severe acute pancreatitis in the rat affects energy metabolism in the pancreas and whether the focal inflammation also causes biochemical deterioration in remote organs such as the liver and intestine.
