Right-to-left-shunts in patients scheduled for neurosurgical intervention in semi-sitting position - a literature review based on two case scenarios.

BACKGROUND: Neurosurgery performed in the semi-sitting position provides advantages for certain procedures. However, this approach is associated with potential complications, particularly venous air embolism. Due to typically negative venous pressure at the wound site, air can be drawn into the veins. This risk is especially high in patients presenting with an intra- or extracardiac right-to-left-shunt. Transoesophageal echocardiography can be used to detect a patent foramen ovale or other possible pulmonary-systemic shunt before placing the patient in the sitting position. CASE PRESENTATION: In this report, we present two young patients undergoing scheduled microsurgical vestibular schwannoma removal in a semi-sitting position who were diagnosed with congenital heart defects during routine perioperative assessment to detect possible intracardiac right-to-left shunts, using pre- and intraoperative transesophageal echocardiography (TEE) and additionally conducting an agitated saline bubble study under Valsalva manoeuvre. Patient A was diagnosed with a persistent left superior vena cava and Patient B with an unroofed coronary sinus (UCS). These findings confronted the anesthesiological and surgical teams with difficult individual decisions regarding further perioperative management. CONCLUSIONS: Perioperative transesophageal echocardiography is a diagnostic tool to both detect intraoperative position-related air embolisms and to rule out intracardiac right-to-left shunts, e.g. a patent foramen ovale, in order to decide for or against a (semi-)sitting position. Depending on the surgical circumstances a semi-sitting positioning of patients presenting with an intracardiac right-to-left-shunt, e.g. a PFO, can be feasible in individual cases if there is an implemented therapeutic algorithm to immediately terminate significant venous air entry. However, since certain other intra- or extracardiac right-to-left-shunts, such as here presented PLSVC or UCS, are rare, there is no definitive way of estimating the amount of entered air through detected shunts or anomalous vessels. Therefore, it is recommended to avoid a (semi-)sitting position in favour of a lateral or prone position for a patient undergoing intracranial surgery, once the perioperative TEE shows air bubbles in the left atrium or ventricle whose origins cannot be defined solely through TEE for certain in order to ensure patient safety by minimizing the risk of intraoperative paradoxical air embolisms.

When to operate after SARS-CoV-2 infection? A review on the recent consensus recommendation of the DGC/BDC and the DGAI/BDA.

Since the eruption of the worldwide SARS-CoV-2 pandemic in late 2019/early 2020, multiple elective surgical interventions were postponed. Through pandemic measures, elective operation capacities were reduced in favour of intensive care treatment for critically ill SARS-CoV-2 patients. Although intermittent low-incidence infection rates allowed an increase in elective surgery, surgeons have to include long-term pulmonary and extrapulmonary complications of SARS-CoV-2 infections (especially "Long Covid") in their perioperative management considerations and risk assessment procedures. This review summarizes recent consensus statements and recommendations regarding the timepoint for surgical intervention after SARS-CoV-2 infection released by respective German societies and professional representatives including DGC/BDC (Germany Society of Surgery/Professional Association of German Surgeons e.V.) and DGAI/BDA (Germany Society of Anesthesiology and Intensive Care Medicine/Professional Association of German Anesthesiologists e.V.) within the scope of the recent literature. The current literature reveals that patients with pre- and perioperative SARS-CoV-2 infection have a dramatically deteriorated postoperative outcome. Thereby, perioperative mortality is mainly caused by pulmonary and thromboembolic complications. Notably, perioperative mortality decreases to normal values over time depending on the duration of SARS-CoV-2 infection.

Bedside hyperspectral imaging indicates a microcirculatory sepsis pattern - an observational study.

INTRODUCTION: Microcirculatory alterations are key mechanisms in sepsis pathophysiology leading to tissue hypoxia, edema formation, and organ dysfunction. Hyperspectral imaging (HSI) is an emerging imaging technology that uses tissue-light interactions to evaluate biochemical tissue characteristics including tissue oxygenation, hemoglobin content and water content. Currently, clinical data for HSI technologies in critical ill patients are still limited. METHODS AND ANALYSIS: TIVITA® Tissue System was used to measure Tissue oxygenation (StO2), Tissue Hemoglobin Index (THI), Near Infrared Perfusion Index (NPI) and Tissue Water Index (TWI) in 25 healthy volunteers and 25 septic patients. HSI measurement sites were the palm, the fingertip, and a suprapatellar knee area. Septic patients were evaluated on admission to the ICU (E), 6 h afterwards (E+6) and three times a day (t3-t9) within a total observation period of 72 h. Primary outcome was the correlation of HSI results with daily SOFA-scores. RESULTS: Serial HSI at the three measurement sites in healthy volunteers showed a low mean variance expressing high retest reliability. HSI at E demonstrated significantly lower StO2 and NPI as well as higher TWI at the palm and fingertip in septic patients compared to healthy volunteers. StO2 and TWI showed corresponding results at the suprapatellar knee area. In septic patients, palm and fingertip THI identified survivors (E-t4) and revealed predictivity for 28-day mortality (E). Fingertip StO2 and THI correlated to SOFA-score on day 2. TWI was consistently increased in relation to the TWI range of healthy controls during the observation time. Palm TWI correlated positively with SOFA scores on day 3. DISCUSSION: HSI results in septic patients point to a distinctive microcirculatory pattern indicative of reduced skin oxygenation and perfusion quality combined with increased blood pooling and tissue water content. THI might possess risk-stratification properties and TWI could allow tissue edema evaluation in critically ill patients. CONCLUSION: HSI technologies could open new perspectives in microcirculatory monitoring by visualizing oxygenation and perfusion quality combined with tissue water content in critically ill patients - a prerequisite for future tissue perfusion guided therapy concepts in intensive care medicine.

[Perioperative fluid management in major abdominal surgery]. / Perioperatives Flüssigkeitsmanagement bei großen viszeralchirurgischen Eingriffen.

Intravascular fluid administration belongs to the cornerstones of perioperative treatment with a substantial impact on surgical outcome especially with respect to major abdominal surgery. By avoidance of hypovolemia and hypervolemia, adequate perioperative fluid management significantly contributes to the reduction of insufficient tissue perfusion as a determinant of postoperative morbidity and mortality. The effective use of intravascular fluids requires detailed knowledge of the substances as well as measures to guide fluid therapy. Fluid management already starts preoperatively and should be continued in the postoperative setting (recovery room, peripheral ward) considering a patient-adjusted and surgery-adjusted hemodynamic monitoring. Communication between all team members participating in perioperative care is essential to optimize fluid management.

[Microvascular changes in COVID-19]. / Mikrovaskuläre Veränderungen bei COVID-19.

BACKGROUND: Clinically, coronavirus disease 2019 (COVID-19) is associated with a wide range of symptoms, which can range from mild complaints of an upper respiratory infection to life-threatening hypoxic respiratory insufficiency and multiorgan failure. OBJECTIVE: The initially identified pulmonary damage patterns, such as diffuse alveolar damage in acute lung failure, are accompanied by new findings that draw a more complex scenario. These include microvascular involvement and a wide range of associated pathologies of multiple organ systems. A back-scaling of microstructural vascular changes is possible via targeted correlation of pathological autopsy results with radiological imaging. MATERIAL AND METHODS: Radiological and pathological correlation as well as microradiological imaging to investigate microvascular involvement in fatal COVID-19. RESULTS: The cases of two COVID-19 patients are presented. Patient 1 showed a relative hypoperfusion in lung regions that did not have typical COVID-19 infiltrates; the targeted post-mortem correlation also showed subtle signs of microvascular damage even in these lung sections. Patient 2 showed both radiologically and pathologically advanced typical COVID-19 destruction of lung structures and the case illustrates the damage patterns of the blood-air barrier. The perfusion deficit of the intestinal wall shown in computed tomography of patient 2 could not ultimately clearly be microscopically attributed to intestinal microvascular damage. CONCLUSION: In addition to microvascular thrombosis, our results indicate a functional pulmonary vasodysregulation as part of the pathophysiology during the vascular phase of COVID-19. The clinical relevance of autopsies and the integration of radiological imaging findings into histopathological injury patterns must be emphasized for a better understanding of COVID-19.

Coherent Excitation of Heterosymmetric Spin Waves with Ultrashort Wavelengths.

In the emerging field of magnonics, spin waves are foreseen as signal carriers for future spintronic information processing and communication devices, owing to both the very low power losses and a high device miniaturization potential predicted for short-wavelength spin waves. Yet, the efficient excitation and controlled propagation of nanoscale spin waves remains a severe challenge. Here, we report the observation of high-amplitude, ultrashort dipole-exchange spin waves (down to 80 nm wavelength at 10 GHz frequency) in a ferromagnetic single layer system, coherently excited by the driven dynamics of a spin vortex core. We used time-resolved x-ray microscopy to directly image such propagating spin waves and their excitation over a wide range of frequencies. By further analysis, we found that these waves exhibit a heterosymmetric mode profile, involving regions with anti-Larmor precession sense and purely linear magnetic oscillation. In particular, this mode profile consists of dynamic vortices with laterally alternating helicity, leading to a partial magnetic flux closure over the film thickness, which is explained by a strong and unexpected mode hybridization. This spin-wave phenomenon observed is a general effect inherent to the dynamics of sufficiently thick ferromagnetic single layer films, independent of the specific excitation method employed.

Intra-abdominal sepsis: new definitions and current clinical standards.

PURPOSE: The abdomen is the second most common source of sepsis and is associated with unacceptably high morbidity and mortality. Recently, the essential definitions of sepsis and septic shock were updated (Third International Consensus Definitions for Sepsis and Septic Shock, Sepsis-3) and modified. The purpose of this review is to provide an overview of the changes introduced by Sepsis-3 and the current state of the art regarding the treatment of abdominal sepsis. RESULTS: While Sepsis-1/2 focused on detecting systemic inflammation as a response to infection, Sepsis-3 defines sepsis as a life-threatening organ dysfunction caused by a dysregulated host response to infection. The Surviving Sepsis Campaign (SSC) guideline, which was updated in 2016, recommends rapid diagnosis and initiating standardized therapy. New diagnostic tools, the establishment of antibiotic stewardship programs, and a host of new-generation antibiotics are new landmark changes in the sepsis literature of the last few years. Although the "old" surgical source control consisting of debridement, removal of infected devices, drainage of purulent cavities, and decompression of the abdominal cavity is the gold standard of surgical care, the timing of gastrointestinal reconstruction and closure of the abdominal cavity ("damage control surgery") are discussed intensively in the literature. The SSC guidelines provide evidence-based sepsis therapy. Nevertheless, treating critically ill intensive care patients requires individualized, continuous daily re-evaluation and flexible therapeutic strategies, which can be best discussed in the interdisciplinary rounds of experienced surgeons and intensive care medicals.

[Perioperative cardiovasular morbidity and mortality in noncardiac surgical interventions : Measures for optimal anesthesiological care]. / Perioperative kardiovaskuläre Morbidität und Letalität bei nichtherzchirurgischen Eingriffen : Maßnahmen der optimalen anästhesiologischen Betreuung.

Because of new surgical techniques, advanced monitoring modalities and improvements in perioperative care, perioperative mortality and morbidity have been significantly reduced in the last decades; however, patients still suffer from high perioperative mortality and morbidity, especially those with pre-existing cardiovascular diseases. Not only perioperative myocardial infarction but also myocardial injury after non-cardiac surgery, which presents without clinical symptoms, is associated with an adverse outcome. Patients at risk require particular interdisciplinary attention throughout the perioperative phase. The premedication visit is of particular importance. In addition to a thorough patient medical history and physical assessment, the perioperative handling of the patient's pre-existing medication and possible necessity for further preoperative tests should be verified. If necessary and where possible, optimization of the patient's state of health can be planned together with other disciplines. It is the anesthesiologist's responsibility to optimally guide and support patients with pre-existing cardiovascular diseases through the entire surgical procedure. This review summarizes perioperative interventions that have an influence on patient mortality and morbidity and evaluates the underlying evidence. This covers the perioperative handling of cardioprotective medication, choice of the anesthetic regimen, blood pressure management and transfusion regimens. Furthermore, this review highlights recent findings, e.g. perioperative reloading with statins and short-term preoperative initiation of beta blockers. The pros and cons of thoracic epidural anesthesia in patients with an elevated cardiovascular risk are discussed. Not only intraoperative hypotension should be of concern to anesthesiologists but also postoperative hypotension can have a deleterious impact on the outcome. This is relevant in the time period when a significant proportion of patients have already left the monitoring ward. The recently published recommendations by the World Health Organization concerning perioperative hyperoxia might not be beneficial for patients with an elevated cardiovascular risk. Finally, the treatment options for perioperative cardiovascular events are explained and an algorithm for handling of patients with perioperative myocardial injury without clinical ischemic symptoms is suggested (myocardial injury after non-cardiac surgery).

[Anesthesiological aspects of liver transplantation]. / Anästhesiologische Aspekte bei der Lebertransplantation.

Liver transplantation (LTPL) is the only curative option for patients with end stage liver disease (ESLD) or with hepatocellular carcinoma (HCC). Eurotransplant in Leiden, the Netherlands, is responsible for organ allocation. The model of end stage liver disease (MELD) score, which describes the severity of the liver disease, is decisive for organ allocation. The heterogeneous patient collective and hepatic-related comorbidities and their dynamics represent challenges. The anesthesiologist is responsible for evaluating the overall prognosis, whereby cardiac, pulmonary, renal and neurological comorbidities must be taken into consideration. During LTPL surgery is divided into several stages. Besides volume management, heat preservation and coagulation management, major challenges for the anesthesiologist are hemodynamic stabilization and regulation of the acid-base balance.

[Conventional intubation and laryngeal tube in cervical spine instability : Changes in the width of the dural sac in unfixed human body donors]. / Konventionelle Intubation und Larynxtubus bei Halswirbelsäuleninstabilität : Änderungen der Duralsackweite am unfixierten humanen Körperspender.

BACKGROUND: Airway management in patients with an unstable cervical spine requires a cautious approach if secondary damage is to be prevented but the question regarding the optimum method remains unresolved. The primary aim of the study was to investigate whether there were differences between intubation by conventional Macintosh laryngoscopy and placement of a laryngeal tube (LTS-D) with respect to dural sac compression on an unfixed human cadaver model with unstable injuries of the upper cervical spine. Secondary parameters that could be relevant in patients with unstable spinal injuries were also investigated. MATERIAL AND METHODS: Orotracheal intubation by conventional direct laryngoscopy using a Macintosh blade and placement of a laryngeal tube (LTS-D) were performed in six fresh human cadavers. The dural sac was filled with contrast dye to allow continuous myelography by lateral fluoroscopy. Changes in the width of the dural sac at the cervical segments (C) C0/C1 and the C1/C2 levels as well as secondary parameters (angulation, distraction, intervention time) were assessed in the intact spine as well as in the presence of combined atlanto-occipital dislocation and atlanto-axial instability. The intubation methods were considered independent and examined using the Mann-Whitney U­test. RESULTS: At the C0/C1 level in the intact spine, conventional laryngoscopy caused less reduction of the width of the dural sac than placement of the LTS-D (0.33 mm vs. 0.46 mm, p = 0.035); however, in the presence of combined atlanto-occipital dislocation and atlanto-axial instability, placement of the LTS-D caused less reduction in the width of the dural sac than conventional intubation (1.18 mm vs. 0.68 mm, p = 0.005). At the C1/C2 level no differences were found with respect to changes in the width of the dural sac, neither in the intact spine nor in combined atlanto-occipital dislocation and atlanto-axial instability. Conventional intubation caused more angulation than placement of the LTS-D at both levels measured. Both methods did not cause distraction. The intervention times for placement of the laryngeal tube were shorter. CONCLUSION: In an unfixed human cadaver model with combined atlanto-occipital dislocation and atlanto-axial instability, placement of the LTS-D caused less reduction in the width of the dural sac than conventional intubation at the level of the craniocervical junction. The LTS-D also caused less angulation and could be placed faster. It could therefore also be advantageous over conventional intubation in living patients with an unstable cervical spine.

[New antibiotics for severe infections due to multidrug-resistant pathogens : Definitive treatment and escalation]. / Neue Antibiotika bei schweren Infektionen durch multiresistente Erreger : Definitive Therapie und Eskalation.

Multidrug-resistant pathogens often lead to treatment failure of antimicrobial regimens. After a period of imbalance between the occurrence/spread of resistance mechanisms and the development of new substances, some new substances have meanwhile been approved and many more are currently undergoing clinical testing. They are particularly effective against specific resistance mechanisms/pathogens and should be preserved for definitive treatment of an isolated pathogen. In the absence of alternatives reserve antibiotics, such as aztreonam and colistin have experienced a renaissance. They are again used in special infection scenarios and clinically tested in combination with new substances. Despite the introduction and development of new substances the building of resistance will at some time also render these (at least partially) ineffective. Therefore, their implementation must be carried out according to the antibiotic or infectious diseases stewardship.

[Infections due to multidrug-resistant pathogens : Pathogens, resistance mechanisms and established treatment options]. / Infektionen durch multiresistente Erreger : Erreger, Resistenzmechanismen und etablierte Therapieoptionen.

The increase in resistant pathogens has long been a global problem. Complicated life-threatening infections due to multidrug-resistant pathogens (MRD) meanwhile occur regularly in intensive care medicine. An important and also potentially modifiable factor of the rapid spread of resistance is the irrational use of broad spectrum antibiotics in human medicine. In addition to many other resistance mechanisms, beta-lactamases play an important role in Gram-negative pathogens. They are not uncommonly the leading reason of difficult to treat infections and the failure of known routinely used broad spectrum antibiotics, such as cephalosporins, (acylamino)penicillins and carbapenems. Strategies for containment of MRDs primaríly target the rational use of antibiotics. In this respect interdisciplinary treatment teams, e.g. antibiotic stewardship (ABS) and infectious diseases stewardship (IDS) play a major role.

Bacterial sepsis : Diagnostics and calculated antibiotic therapy.

The mortality of patients with sepsis and septic shock is still unacceptably high. An effective calculated antibiotic treatment within 1 h of recognition of sepsis is an important target of sepsis treatment. Delays lead to an increase in mortality; therefore, structured treatment concepts form a rational foundation, taking relevant diagnostic and treatment steps into consideration. In addition to the assumed infection and individual risks of each patient, local resistance patterns and specific problem pathogens must be taken into account during the selection of anti-infective treatment. Many pathophysiologic alterations influence the pharmacokinetics (PK) of antibiotics during sepsis. The principle of standard dosing should be abandoned and replaced by an individual treatment approach with stronger weighting of the pharmacokinetics/pharmacodynamics (PK/PD) index of the substance groups. Although this is not yet the clinical standard, prolonged (or continuous) infusion of ß­lactam antibiotics and therapeutic drug monitoring (TDM) can help to achieve defined PK targets. Prolonged infusion is sufficient without TDM, but for continuous infusion, TDM is generally necessary. A further argument for individual PK/PD-oriented antibiotic approaches is the increasing number of infections due to multidrug-resistant (MDR) pathogens in the intensive care unit. For effective treatment, antibiotic stewardship teams (ABS teams) are becoming more established. Interdisciplinary cooperation of the ABS team with infectious disease (ID) specialists, microbiologists, and clinical pharmacists leads not only to rational administration of antibiotics, but also has a positive influence on treatment outcome. The gold standards for pathogen identification are still culture-based detection and microbiologic resistance testing for the various antibiotic groups. Despite the rapid investigation time, novel polymerase chain reaction(PCR)-based procedures for pathogen identification and resistance determination are currently only an adjunct to routine sepsis diagnostics, due to the limited number of studies, high costs, and limited availability. In complicated septic courses with multiple anti-infective therapies or recurrent sepsis, PCR-based procedures can be used in addition to treatment monitoring and diagnostics. Novel antibiotics represent potent alternatives in the treatment of MDR infections. Due to the often defined spectrum of pathogens and the practically (still) absent resistance, they are suitable for targeted treatment of severe MDR infections (therapy escalation).

Stellar

The ^{36}Ar(n,γ)^{37}Ar (t_{1/2}=35 d) and ^{38}Ar(n,γ)^{39}Ar (269 yr) reactions were studied for the first time with a quasi-Maxwellian (kT∼47 keV) neutron flux for Maxwellian average cross section (MACS) measurements at stellar energies. Gas samples were irradiated at the high-intensity Soreq applied research accelerator facility-liquid-lithium target neutron source and the ^{37}Ar/^{36}Ar and ^{39}Ar/^{38}Ar ratios in the activated samples were determined by accelerator mass spectrometry at the ATLAS facility (Argonne National Laboratory). The ^{37}Ar activity was also measured by low-level counting at the University of Bern. Experimental MACS of ^{36}Ar and ^{38}Ar, corrected to the standard 30 keV thermal energy, are 1.9(3) and 1.3(2) mb, respectively, differing from the theoretical and evaluated values published to date by up to an order of magnitude. The neutron-capture cross sections of ^{36,38}Ar are relevant to the stellar nucleosynthesis of light neutron-rich nuclides; the two experimental values are shown to affect the calculated mass fraction of nuclides in the region A=36-48 during the weak s process. The new production cross sections have implications also for the use of ^{37}Ar and ^{39}Ar as environmental tracers in the atmosphere and hydrosphere.

Implementation of the Sepsis-3 definition in German university intensive care units : A survey.

BACKGROUND: The old definition of sepsis was replaced by Sepsis-3 in February 2016. The new screening diagnostic tools sequential organ failure assessment (SOFA) score and quick SOFA (qSOFA) score were incorporated into the definition. The resulting scientific controversy led to several retrospective and prospective evaluations. In contrast no evaluation of the state of play of national implementation of Sepsis-3 has been conducted so far. OBJECTIVE: The aim of this study was to capture the current situation in German academic intensive care units 1 year after the implementation of Sepsis-3. METHODS: An internet-based questionnaire consisting of 22 items was developed. The identification of eligible departments was performed by an online search of the homepages of all university hospitals located in Germany. Departments regardless of the discipline with an explicit indication of involvement in intensive care were extracted. The link to the internet-based questionnaire was sent to all identified departments on 22 February 2017 and was accessible for 19 days. RESULTS: Out of 259 departments 76 answered the online survey. The response rate was 29.3% from 13 specializations. Anesthesiology, internal medicine and general surgery were the three main participants in this study. The majority of intensive care units (54.75%) treated more than 100 patients with sepsis or septic shock annually and more than 30% treated more than 250 patients. While 76.7% of respondents had a standard operating procedure, 55% of those were based on the Sepsis-3 definition. When asked to rate the usefulness of the Sepsis-3 definition, answers were heterogeneous with a slight tendency towards a higher usefulness and the majority (72.9%) were in favor of Sepsis-3 being included in the national S2K guidelines. CONCLUSION: The results demonstrate the heterogeneity of Sepsis-3 implementation in German intensive care units. Sepsis-3 is finding its way but there is a need for standardized implementation.

[Adequate anti-infective treatment : Importance of individual dosing and application]. / Adäquate Antiinfektivatherapie : Bedeutung der individuellen Dosierung und Applikation.

Sepsis-induced changes in pharmacokinetic parameters are a well-known problem in intensive care medicine. Dosing of antibiotics in this setting is therefore challenging. Alterations to the substance-specific kinetics of anti-infective substances have an effect on the distribution and excretion processes in the body. Increased clearance and an increased distribution volume (Vd) and particularly compromized organ function with reduced antibiotic elimination are often encountered in patients with sepsis. Renal replacement treatment, which is frequently used in intensive care medicine, represents a substantial intervention in this system. Current international guidelines recommend individualized dosing strategies and adaptation of doses according to measured serum levels and pharmacokinetic/pharmacodynamic (PK/PD) parameters as concepts to optimize anti-infective therapy in the critically ill. Likewise, the recommendation to adjust the administration form of beta-lactam antibiotics to prolonged or continuous infusion can be found increasingly more often in the literature. This article reviews the background of the individual dosing in intensive care patients and their applicability to the clinical routine.

The impact of real life treatment strategies for Candida peritonitis-A retrospective analysis.

Candida species are commonly detected isolates from abdominal foci. The question remains as to who would benefit from early empiric treatment in cases of Candida peritonitis. This study collected real-life data on critically ill patients with Candida peritonitis to estimate the relevance of the chosen treatment strategy on the outcome of these patients. One hundred and thirty-seven surgical intensive care unit (ICU) patients with intra-abdominal invasive Candidiasis were included in the study. Fifty-six patients did not get any antifungal agent. Twenty-nine patients were empirically treated, and 52 patients were specifically treated. In the group without, with empiric and with specific antifungal treatment, the 30-day mortality rate was 33.9, 48.3 and 44.2 respectively. Candida albicans was the most frequently found species. Seven patients in the specific treatment group and one patient in the empiric treatment group emerged with candidaemia. Age, leucocyte count, APACHE II Score and acute liver failure were independent predictors of 30-day mortality in patients with Candida peritonitis. Not all patients with Candida peritonitis received antifungal treatment in real clinical practice. Patients with higher morbidity more often got antifungals. Early empirical therapy has not been associated with a better 30-day mortality.

[Establishment of the new cross-sectional field of pain medicine : An application example at the medical faculty of Heidelberg]. / Etablierung des neuen Querschnittsbereichs Schmerzmedizin : Ein Anwendungsbeispiel der Medizinischen Fakultät Heidelberg.

Studies from recent years paint a picture of qualitatively deficient treatment in pain medicine. In order to improve the situation knowledge on targeted diagnostics and effective therapy should be imparted at an early stage during undergraduate studies. For this reason the cross-sectional field Q14 - pain medicine was newly created in the revision of the medical physician licencing regulations. The Q14 was then established in a longitudinal, multidisciplinary form at the medical faculty in Heidelberg, whereby the complete Kern cycle was run through. The present project report describes and discusses the establishment. The results of the first multiple choice examination and an online-based evaluation by the students are presented. The latter show that the students recognized the relevance of the teaching program for their future professional career; however, the presentation of the interdisciplinary aspect must still be improved. The students were critical of the longitudinal structure and this does indeed involve a great deal of organization for the faculty and students. On the other hand this corresponds to the basic conception of a cross-sectional field and gives a good depiction of the multidisciplinary character. The first evaluation results set the precedent for further fine adjustments of the cross-sectional field. A continuous further development is generally needed with respect to the Kern cycle.

[New Sepsis-3 definition : Do we have to treat sepsis before we can diagnose it from now on?] / Neue SEPSIS-3-Definition : Müssen wir Sepsis in Zukunft behandeln, bevor wir sie diagnostizieren dürfen?

The Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) have been available since the beginning of 2016. SEPSIS-3 completely replaces the old SIRS criteria in the definition of sepsis and defines sepsis from now on as "life-threatening organ dysfunction caused by a dysregulated host response to infection". However, it seems questionable whether in clinical practice the new definition is really superior to the old one. The most important question is the following: Is it helpful to have a definition that first recognizes a patient once organ dysfunction has occurred and the patient already needs intensive care?

[Interprofessional symptom management at the end of life]. / Interprofessionelle Symptomkontrolle am Lebensende.

At the end of life patients often show distressful symptoms which significantly reduce their quality of life. The goal of all healthcare professionals should be to recognize the beginning of this end of life period in order to provide good symptom management. For this purpose, existing symptoms have to be recorded, suitable therapeutic goals have to be defined for the current situation and potential therapeutic strategies have to be individually formulated. Besides the identification of underlying causes with the possibility of causal treatment, a symptom-based therapy is often necessary. Therapeutic approaches of different professions should be equally considered and should additionally be used for the benefit of the patient.
