The frequency of mechanical circulatory support (MCS) device application has increased in recent years. Besides implantation in the emergency setting, such as circulatory arrest, MCS is also increasingly used electively to ensure hemodynamic stability in high-risk patients, for example, during percutaneous coronary interventions (PCI), valve interventions or off-pump coronary bypass surgery. Lifebridge (Zoll Medical GmbH, Germany) is a compact percutaneous MCS device widely used in daily clinical routine. The present study aimed to investigate the indications, feasibility, and outcomes after use of Lifebridge in cardiac interventions, evaluating a large-scale multicenter database. A total of 60 tertiary cardiovascular centers were questioned regarding application and short-term outcomes after the use of the Lifebridge system (n = 160 patients). Out of these 60 centers, eight consented to participate in the study (n = 39 patients), where detailed data were collected using standardized questionnaires. Demographic and clinical characteristics of the patient population, procedural as well as follow-up data were recorded and analyzed. In 60 interrogated centers, Lifebridge was used in 74% of emergency cases and 26% in the setting of planned interventions. The subcohort interrogated in detail displayed the same distribution of application scenarios, while the main cardiovascular procedure was high-risk PCI (82%). All patients were successfully weaned from the device and 92% (n = 36) of the patients studied in detail survived after 30 days. As assessed 30 days after insertion of the device, bleeding requiring red blood cell (RBC) transfusion constituted the main complication, occurring in 49% of cases. In our analysis of clinical data, the use of Lifebridge in cardiac intervention was shown to be feasible. Further prospective studies are warranted to identify patients who benefit from hemodynamic MCS support despite the increased rate of RBC transfusion due to challenges in access sites during cardiovascular procedures., (© 2020 The Authors.

Purpose: The approach to limit therapy in very old intensive care unit patients (VIPs) significantly differs between regions. The focus of this multicenter analysis is to illuminate, whether the Clinical Frailty Scale (CFS) is a suitable tool for risk stratification in VIPs admitted to intensive care units (ICUs) in Germany. Furthermore, this investigation elucidates the impact of therapeutic limitation on the length of stay and mortality in this setting., Methods: German cohorts' data from two multinational studies (VIP-1, VIP-2) were combined. Univariate and multivariate logistic regression were used to evaluate associations with mortality., Results: 415 acute VIPs were included. Frail VIPs (CFS > 4) were older (85 [IQR 82-88] vs. 83 [IQR 81-86] years p < .001) and suffered from an increased 30-day-mortality (43.4% versus 23.9%, p < .0001). CFS was an independent predictor of 30-day-mortality in a multivariate logistic regression model (aOR 1.23 95%CI 1.04-1.46 p = .02). Patients with any limitation of life-sustaining therapy had a significantly increased 30-day mortality (86% versus 16%, p < .001) and length of stay (144 [IQR 72-293] versus 96 [IQR 47.25-231.5] hours, p = .026)., Conclusion: In German ICUs, any limitation of life-sustaining therapy in VIPs is associated with a significantly increased ICU length of stay and mortality. CFS reliably predicts the outcome., Competing Interests: Declaration of Competing Interest None., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Background: The concept of percutaneous extracorporeal life support (ECLS) is based on immediate cardiovascular stabilization allowing for sufficient end-organ perfusion, thus improving the outcome in patients with circulatory arrest. Lifebridge ® (Zoll Medical GmbH, Germany) is a portable ECLS device designed for rapid application due to its automated set-up., Methods: A total of 60 tertiary cardiovascular centers were interrogated with regard to application and short-term results after use of Lifebridge ECLS system. Detailed data were collected by standardized case report forms in all centers consented to participate in the study. Demographic and clinical baseline characteristics of the patient population, procedural and follow-up data were recorded and analyzed., Results: In total, 444 patients were analyzed regarding mortality. The detailed study cohort consisted of 112 patients. A total of 80% of the study subjects represented patients post cardiopulmonary resuscitation, 43% were in cardiogenic shock and 50% suffered from acute myocardial infarction. The survival rates were 36% immediately after device implementation and 16% after 30 days. Multivariable analysis revealed that only serum lactate concentration at admission could be proven as independent predictor of patients' outcome. Patients with lactate concentrations above 10 mmol/L exhibited > 95% mortality (p < 0.05 versus below 10 mmol/L)., Conclusion: The present study provides real-world clinical data of patients treated with a transportable automated ECLS system. In conclusion, Lifebridge is a safely applicable cardiorespiratory stabilization tool associated with acceptable complication rates. Nevertheless, mortality rates were high in these critically ill patients, especially in those showing high lactate concentrations at admission.

Purpose: Enteral and parenteral nutrition of adult critically ill patients varies in terms of the route of nutrient delivery, the amount and composition of macro- and micronutrients, and the choice of specific, immune-modulating substrates. Variations of clinical nutrition may affect clinical outcomes. The present guideline provides clinicians with updated consensus-based recommendations for clinical nutrition in adult critically ill patients who suffer from at least one acute organ dysfunction requiring specific drug therapy and/or a mechanical support device (e.g., mechanical ventilation) to maintain organ function., Methods: The former guidelines of the German Society for Nutritional Medicine (DGEM) were updated according to the current instructions of the Association of the Scientific Medical Societies in Germany (AWMF) valid for a S2k-guideline. According to the S2k-guideline classification, no systematic review of the available evidence was required to make recommendations, which, therefore, do not state evidence- or recommendation grades. Nevertheless, we considered and commented the evidence from randomized-controlled trials, meta-analyses and observational studies with adequate sample size and high methodological quality (until May 2018) as well as from currently valid guidelines of other societies. The liability of each recommendation was described linguistically. Each recommendation was finally validated and consented through a Delphi process., Results: In the introduction the guideline describes a) the pathophysiological consequences of critical illness possibly affecting metabolism and nutrition of critically ill patients, b) potential definitions for different disease phases during the course of illness, and c) methodological shortcomings of clinical trials on nutrition. Then, we make 69 consented recommendations for essential, practice-relevant elements of clinical nutrition in critically ill patients. Among others, recommendations include the assessment of nutrition status, the indication for clinical nutrition, the timing and route of nutrient delivery, and the amount and composition of substrates (macro- and micronutrients); furthermore, we discuss distinctive aspects of nutrition therapy in obese critically ill patients and those treated with extracorporeal support devices., Conclusion: The current guideline provides clinicians with up-to-date recommendations for enteral and parenteral nutrition of adult critically ill patients who suffer from at least one acute organ dysfunction requiring specific drug therapy and/or a mechanical support device (e.g., mechanical ventilation) to maintain organ function. The period of validity of the guideline is approximately fixed at five years (2018-2023)., (Copyright © 2019 European Society for Clinical Nutrition and Metabolism. Published by Elsevier Ltd.

Background: Second-generation cryoballoon (CB2)-based pulmonary vein isolation (PVI) has demonstrated encouraging results in the treatment of atrial fibrillation (AF). This study sought to assess data on the safety, efficacy and clinical success of CB2-based PVI in patients with heart failure (HF) and reduced ejection fraction (HFrEF).Methods and Results:CB2-based PVI was performed in 551 consecutive patients in 3 highly experienced EP centers. Patients with HF and LVEF ≤40% were included (HFrEF group, n=50/551, 9.1%). Data were compared with propensity score-matched patients without HF and preserved left ventricular EF (LVEF) (n=50, control group). The median LVEF was HFrEF: 37% (35, 40) and control: 55% (55, 55), P<0.0001. Major periprocedural complications were registered in 4/50 (8%, HFrEF group) and 3/50 (6%, control group), P=0.695. The 12-month freedom from AF recurrence was 73.1% (95% confidence interval (CI): 61-88, HFrEF group) and 72.6% (95% CI: 61-87, control group), P=0.25. NYHA class decreased from 2.4±0.8 (baseline) to 1.7±0.8 at 12-month follow-up (P<0.0001). LVEF improved from a median of 37% (35, 40) prior to ablation to a median of 55% (40, 55), P<0.0001., Conclusions: CB2-based PVI in patients with HFrEF appeared to be safe, was associated with comparable periprocedural complications and showed promising clinical success rates equal to those for patients with preserved LVEF. NYHA class and LVEF significantly improved at 12-month follow-up.

Purpose: Variations of clinical nutrition may affect outcome of critically ill patients. Here we present the short version of the updated consenus-based guideline (S2k classification) "Clinical nutrition in critical care medicine" of the German Society for Nutritional Medicine (DGEM) in cooperation with 7 other national societies. The target population of the guideline was defined as critically ill adult patients who suffer from at least one acute organ dysfunction requiring specific drug therapy and/or a mechanical support device (e.g. mechanical ventilation) to maintain organ function., Methods: The former guidelines of the German Society for Nutritional Medicine (DGEM) were updated according to the current instructions of the Association of the Scientific Medical Societies in Germany (AWMF) valid for a S2k-guideline. We considered and commented the evidence from randomized-controlled trials, meta-analyses and observational studies with adequate sample size and high methodological quality (until May 2018) as well as from currently valid guidelines of international societies. The liability of each recommendation was indicated using linguistic terms. Each recommendation was finally validated and consented by a Delphi process., Results: The short version presents a summary of all 69 consented recommendations for essential, practice-relevant elements of clinical nutrition in the target population. A specific focus is the adjustment of nutrition according to the phases of critical illness, and to the individual tolerance to exogenous substrates. Among others, recommendations include the assessment of nutritional status, the indication for clinical nutrition, the timing, route, magnitude and composition of nutrition (macro- and micronutrients) as well as distinctive aspects of nutrition therapy in obese critically ill patients and those with extracorporeal support devices., Conclusion: The current short version of the guideline provides a concise summary of the updated recommendations for enteral and parenteral nutrition of adult critically ill patients who suffer from at least one acute organ dysfunction requiring pharmacological and/or mechanical support. The validity of the guideline is approximately fixed at five years (2018 - 2023)., Competing Interests: Die Interessenkonflikte der Autoren sind in Tab. 2 aufgelistet., (Georg Thieme Verlag KG Stuttgart · New York.)

Background: In intensive care units (ICU) octogenarians become a routine patients group with aggravated therapeutic and diagnostic decision-making. Due to increased mortality and a reduced quality of life in this high-risk population, medical decision-making a fortiori requires an optimum of risk stratification. Recently, the VIP-1 trial prospectively observed that the clinical frailty scale (CFS) performed well in ICU patients in overall-survival and short-term outcome prediction. However, it is known that healthcare systems differ in the 21 countries contributing to the VIP-1 trial. Hence, our main focus was to investigate whether the CFS is usable for risk stratification in octogenarians admitted to diversified and high tech German ICUs., Methods: This multicentre prospective cohort study analyses very old patients admitted to 20 German ICUs as a sub-analysis of the VIP-1 trial. Three hundred and eight patients of 80 years of age or older admitted consecutively to participating ICUs. CFS, cause of admission, APACHE II, SAPS II and SOFA scores, use of ICU resources and ICU- and 30-day mortality were recorded. Multivariate logistic regression analysis was used to identify factors associated with 30-day mortality., Results: Patients had a median age of 84 [IQR 82-87] years and a mean CFS of 4.75 (± 1.6 standard-deviation) points. More than half of the patients (53.6%) were classified as frail (CFS ≥ 5). ICU-mortality was 17.3% and 30-day mortality was 31.2%. The cause of admission (planned vs. unplanned), (OR 5.74) and the CFS (OR 1.44 per point increase) were independent predictors of 30-day survival., Conclusions: The CFS is an easy determinable valuable tool for prediction of 30-day ICU survival in octogenarians, thus, it may facilitate decision-making for intensive care givers in Germany., Trial Registration: The VIP-1 study was retrospectively registered on ClinicalTrials.gov (ID: NCT03134807 ) on May 1, 2017.

Ambulatory blood pressure (BP) and central BP are better predictors for overall cardiovascular risk and mortality than brachial BP. Renal denervation (RDN) has been shown to reduce office brachial and central BP as well as brachial ambulatory BP, but data on central ambulatory BP are limited. Patients (N = 94) with treatment resistant hypertension (TRH) who underwent RDN were included. Ambulatory BP, including central pressures, hemodynamics, and arterial stiffness were measured at baseline and 3, 6, 12 months after RDN by an oscillometric device (MobiloGraph ™ ). At 3, 6, and 12-month follow-ups, brachial ambulatory BP was reduced (P for all < .001). Consistently, central ambulatory BP was reduced (P for all < .001). Ambulatory assessed averaged daytime pulse wave velocity improved after RDN (P < .05). Total vascular resistance decreased (P for all < .01). In patients with TRH, RDN improves brachial and central ambulatory BP, arterial stiffness, and total vascular resistance, indicating an improvement of cardiovascular outcome., (©2018 Wiley Periodicals, Inc.)

The German Society for the Study of Pain has formed an interdisciplinary committee to answer urgent ethical questions on the diagnosis and treatment of pain and to give an ethical orientation on the care of pain and palliative patients. The treatment of pain is a fundamental objective of medicine. Competent and adequate relief of pain in all stages of life is a basic characteristic of a humane medicine oriented to the quality and meaning of life for people. However, there are substantial deficits in all areas, especially in the knowledge of physicians and patients, in training and further education, diagnosis and therapy. Freedom from pain is a substantial element of quality of life. A central duty of all physicians is an adequate diagnosis and treatment of acute pain and thereby the prophylaxis of chronic pain. If pain persists over a longer period of time, it loses the warning function and becomes taken for granted. Alterations, disabilities and limitations of the physical, psychic and social levels are the consequences. For these patients an interdisciplinary approach is necessary by which various medical disciplines, psychologists and physiotherapists are involved and all collaborate on the diagnosis and therapy of pain. All patients have the right to sufficient and individually tailored treatment of pain. Special attention must be paid to vulnerable patient groups, such as newborns, children and adolescents, as well as aged and mentally retarded patients. For cancer patients pain relief of their tumor pain is totally in the forefront. Indications of "unbearable pain" must not lead to resignation or even be seen as an argument for legalization of "death on request". The nursing of terminally ill patients necessitates a special measure not only of clinical, but also ethical competence, communication and multiprofessional collaboration. The modern options for palliative care are real alternatives to demands for legalization of "death on request". Physician-assisted suicide does not belong to the scope of functions of palliative medicine. The basic constitutional law makes an appropriate treatment of pain obligatory. Neglect of pain treatment fulfils the elements of criminal bodily harm. As a consequence, there is a legal right to a comprehensive pain diagnosis and a pain treatment corresponding to the appropriate standard. The state is obliged to provide the legal, social and financial prerequisites for an adequate treatment of pain. Continuous efforts in research are necessary to fill the existing gaps in our knowledge. The transfer between basic research and clinical application of pain therapy must be urgently improved. Of central importance for the German Pain Society are therefore: Improvement of training and further education in pain therapy. Chronic pain must be accepted and coded as an autonomous sickness. Graded structures for care of pain patients must be realized. Interdisciplinary structures of care must be made available to patients with chronic pain. Palliative medical care is a basic right of all terminally ill patients. Politics and health care providers must establish prerequisites for adequate pain diagnosis, pain therapy and palliative medicine.

On the basis of the current anti-doping requirements for the World Cup, major processes and regulations are explained. Over and beyond the area of football, they are highly relevant for physicians responsible for the care and treatment of professional athletes. Apart from a knowledge of the respective current anti-doping list of banned substances, the administrative guidelines for the application to use notifiable substances must be complied with. In order to avoid errors resulting in serious consequences for athletes, the care-providing physician in professional sport must have immediate access to the necessary information on anti-doping regulations, and be familiar with the contact addresses of the respective anti-doping authorities.
