(1) Background: Acute kidney injury (AKI) is a common complication following thoracic aortic surgery (TAS), with moderate hypothermic circulatory arrest (MHCA). However, prediction of AKI with classical tools remains uncertain. Therefore, it was the aim of the present study to evaluate the role of new biomarkers in patients after MHCA.

Use of extracorporeal circulation (ECLS/ECMO) for cardiac and circulatory failure -A clinical practice Guideline Level 3.

Aims Worldwide applications of extracorporeal circulation for mechanical support in cardiac and circulatory failure, which are referred to as extracorporeal life support (ECLS) or veno-arterial extracorporeal membrane oxygenation (va-ECMO), have dramatically increased over the past decade. In spite of the expanding use and the immense medical as well as socio-economic impact of this therapeutic approach, there has been a lack of interdisciplinary recommendations considering the best available evidence for ECLS treatment. Methods and Results In a multiprofessional, interdisciplinary scientific effort of all scientific societies involved in the treatment of patients with acute cardiac and circulatory failure, the first evidence- and expert consensus-based guideline (level S3) on ECLS/ECMO therapy was developed in a structured approach under regulations of the AWMF (Association of the Scientific Medical Societies in Germany) and under use of GRADE (Grading of Recommendations Assessment, Development and Evaluation) criteria.

[Use of extracorporeal circulation (ECLS/ECMO) for cardiac and circulatory failure : Short version of the S3 guideline].

In Germany, a remarkable increase regarding the usage of extracorporeal membrane oxygenation (ECMO) and extracorporeal life support (ECLS) systems has been observed in recent years with approximately 3000 ECLS/ECMO implantations annually since 2015. Despite the widespread use of ECLS/ECMO, evidence-based recommendations or guidelines are still lacking regarding indications, contraindications, limitations and management of ECMO/ECLS patients. Therefore in 2015, the German Society of Thoracic and Cardiovascular Surgery (GSTCVS) registered the multidisciplinary S3 guideline "Use of extracorporeal circulation (ECLS/ECMO) for cardiac and circulatory failure" to develop evidence-based recommendations for ECMO/ECLS systems according to the requirements of the Association of the Scientific Medical Societies in Germany (AWMF).

[Extracorporeal cardiopulmonary resuscitation (eCPR)].

Extracorporeal cardiopulmonary resuscitation (eCPR) is the implementation of extracorporeal membrane oxygenation (ECMO) in selected patients with cardiac arrest and may be considered when conventional CPR efforts fail, as written in the latest international guidelines. eCPR is a complex intervention that requires a highly trained team, specialized equipment, and multidisciplinary support within a healthcare system and it has the risk of several life-threatening complications. However, there are no randomized, controlled studies on eCPR, and valid predictors of benefit and outcome are lacking.

[Training module extracorporeal life support (ECLS): consensus statement of the DIVI, DGTHG, DGfK, DGAI, DGIIN, DGF, GRC and DGK].

Mechanical circulatory support using extracorporeal life support systems (ECLS) has significantly increased in recent years. These critically ill patients pose special challenges to the multiprofessional treatment team and require comprehensive, interdisciplinary and interprofessional concepts. For this reason, to ensure the best possible patient care a standardized ECLS training module has been created at national specialist society level, taking emergency and intensive care management into account.

The German-Austrian S3 Guideline "Cardiogenic Shock Due to Myocardial Infarction: Diagnosis, Monitoring, and Treatment".

Despite advances in the treatment of acute myocardial infarction with subsequent mortality reduction, which are mainly caused by the early timing of revascularization, cardiogenic shock still remains the leading cause of death with mortality rates still approaching 40 to 50%. Cardiogenic shock is characterized by a multiorgan dysfunction syndrome, often complicated by a systemic inflammatory response syndrome that affects the outcome more than the reduction of the cardiac contractile function. However, both European and American guidelines on myocardial infarction focus on interventional or surgical aspects only.

[Short version of the 2nd edition of the German-Austrian S3 guidelines "Cardiogenic shock complicating myocardial infarction-Diagnosis, monitoring and treatment"].

Background: The present guidelines ( http://leitlinien.net ) focus exclusively on cardiogenic shock due to myocardial infarction (infarction-related cardiogenic shock, ICS). The cardiological/cardiac surgical and the intensive care medicine strategies dealt with in these guidelines are essential to the successful treatment and survival of patients with ICS; however, both European and American guidelines on myocardial infarction and heart failure and also position papers on cardiogenic shock focused mainly on cardiological aspects.

[Recommendations for emergency management of patients with permanent mechanical circulatory support : Consensus statement of DGTHG, DIVI, DGIIN, DGAI, DGINA, DGfK and DGK].

The prevalence of patients living with long-term mechanical circulatory support (MCS) is rapidly increasing due to improved technology, improved survival, reduced adverse event profiles, greater reliability and mechanical durability, and limited numbers of organs available for donation. Patients with long-term MCS are very likely to require emergency medical support due to MCS-associated complications (e.g.

[Acute right heart failure on the intensive care unit : Pathophysiology, monitoring and management].

Right ventricular heart failure is a frequent and serious but often undetected and complex clinical challenge on the intensive care unit. The commonest causes include acute decompensation of pulmonary hypertension, pulmonary embolism, sepsis, acute respiratory distress, and cardiothoracic surgery. The gold standard of bedside diagnosis is a combination of clinical symptoms, biochemical markers (NT-proBNP) and echocardiography.

Prediction of acute kidney injury after left ventricular assist device implantation: Evaluation of clinical risk scores.

Acute kidney injury (AKI) is frequent in patients scheduled for implantation of a left ventricular assist device (LVAD) and associated with increased mortality. Although several risk models for the prediction of postoperative renal replacement therapy (RRT) have been developed for cardiothoracic patients, none of these scoring systems have been validated in LVAD patients. A retrospective, single center analysis of all patients undergoing LVAD implantation between September 2013 and July 2016 was performed.

Hardware Realization of the Pattern Recognition with an Artificial Neuromorphic Device Exhibiting a Short-Term Memory.

Materials exhibiting memory or those capable of implementing certain learning schemes are the basic building blocks used in hardware realizations of the neuromorphic computing. One of the common goals within this paradigm assumes the integration of hardware and software solutions, leading to a substantial efficiency enhancement in complex classification tasks. At the same time, the use of unconventional approaches towards signal processing based on information carriers other than electrical carriers seems to be an interesting trend in the design of modern electronics.

Multiplex polymerase chain reaction to diagnose bloodstream infections in patients after cardiothoracic surgery.

Background: Sepsis and other infectious complications are major causes of mortality and morbidity in patients after cardiac surgery. Whereas conventional blood culture (BC) suffers from low sensitivity as well as a reporting delay of approximately 48-72 h, real-time multiplex polymerase chain reaction (PCR) based technologies like "SeptiFast" (SF) might offer a fast and reliable alternative for detection of bloodstream infections (BSI). The aim of this study was to compare the performance of SF with BC testing in patients suspected of having BSI after cardiac surgery.
