Role and benefits of infectious diseases specialists in the COVID-19 pandemic: Multilevel analysis of care provision in German hospitals using data from the Lean European Open Survey on SARS-CoV-2 infected patients (LEOSS) cohort.

Purpose: This study investigates the care provision and the role of infectious disease (ID) specialists during the coronavirus disease-2019 (COVID-19) pandemic.

Methods: A survey was conducted at German study sites participating in the Lean European Open Survey on SARS-CoV-2 infected patients (LEOSS). Hospitals certified by the German Society of Infectious diseases (DGI) were identified as ID centers.

Efficacy and Safety of ELOM-080 as Add-On Therapy in COVID-19 Patients with Acute Respiratory Insufficiency: Exploratory Data from the Prospective Placebo-Controlled COVARI Trial.

Introduction: Enhancement of mucociliary clearance (MCC) might be a potential target in treating COVID-19. The phytomedicine ELOM-080 is an MCC enhancer that is used to treat inflammatory respiratory diseases.

Patients/methods: This randomised, double-blind exploratory study (EudraCT number 2020-003779-17) evaluated 14 days' add-on therapy with ELOM-080 versus placebo in patients with COVID-19 hospitalised with acute respiratory insufficiency.

Angiography after Out-of-Hospital Cardiac Arrest without ST-Segment Elevation.

Background: Myocardial infarction is a frequent cause of out-of-hospital cardiac arrest. However, the benefits of early coronary angiography and revascularization in resuscitated patients without electrocardiographic evidence of ST-segment elevation are unclear.

Methods: In this multicenter trial, we randomly assigned 554 patients with successfully resuscitated out-of-hospital cardiac arrest of possible coronary origin to undergo either immediate coronary angiography (immediate-angiography group) or initial intensive care assessment with delayed or selective angiography (delayed-angiography group).

Therapy limitation in octogenarians in German intensive care units is associated with a longer length of stay and increased 30 days mortality: A prospective multicenter study.

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.

Clinical Nutrition in Critical Care Medicine - Guideline of the German Society for Nutritional Medicine (DGEM).

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.

Noninvasive ventilation: education and training. A narrative analysis and an international consensus document.

Noninvasive ventilation (NIV) is an increasingly used method of respiratory support. The use of NIV is expanding over the time and if properly applied, it can save patients' lives and improve long-term prognosis. However, both knowledge and skills of its proper use as life support are paramount.

Immediate unselected coronary angiography versus delayed triage in survivors of out-of-hospital cardiac arrest without ST-segment elevation: Design and rationale of the TOMAHAWK trial.

Patients experiencing out-of-hospital cardiac arrest (OHCA) without ST-segment elevation are a heterogenic group with a variety of underlying causes. Up to one-third of patients display a significant coronary lesion compatible with myocardial infarction as OHCA trigger. There are no randomized data on patient selection and timing of invasive coronary angiography after admission.

[DGEM Guideline "Clinical Nutrition in Critical Care Medicine" - short version].

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.

Clinical Frailty Scale (CFS) reliably stratifies octogenarians in German ICUs: a multicentre prospective cohort study.

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.

Oxygen dependence of endothelium-dependent vasodilation: importance in chronic obstructive pulmonary disease.

Introduction: Epidemiological studies have shown increased morbidity and mortality in patients with coronary artery disease (CAD) and chronic obstructive pulmonary disease (COPD). We aimed to characterize the oxygen dependence of endothelial function in patients with CAD and coexisting COPD.

Material And Methods: In CAD patients with and without COPD ( = 33), we non-invasively measured flow-mediated dilation (FMD) and intima-media thickness (IMT) of the brachial artery (BA), forearm blood flow (FBF), and perfusion of the cutaneous microcirculation with laser Doppler perfusion imaging (LDPI).

Impact of Continuous Positive Airway Pressure on Left Ventricular Systolic Loading and Coronary Flow Reserve in Healthy Young Men.

Background: Increased augmentation index (AIx) is accompanied by an elevated cardiovascular risk. A reduction of AIx is known for long-term continuous positive airway pressure (CPAP) therapy. We hypothesised that acute preload and left ventricular workload effects AIx and subendocardial viability ratio (SEVR) as a marker of coronary flow reserve.

Pulmonary Cytomegalovirus Replication in Renal Transplant Patients with Late Onset Pneumonitis.

Background: In renal transplant patients, pneumonitis may be caused by cytomegalovirus (CMV pneumonitis). This condition is usually accompanied by CMV viremia. However, CMV may also reactivate locally in the lungs of renal transplant patients with pneumonitis due to other pathogens.

"Lung packing" in breath hold-diving: An impressive case of pulmo-cardiac interaction.

There is a complex interaction between the heart and the lungs. We report on a healthy female who performs breath hold diving at a high, international level. In order to optimize pressure equalization during diving and to increase oxygen available, apneists employed a special breathing maneuver, so called "lung packing".

Severe aortic valve stenosis in the elderly: high prevalence of sleep-related breathing disorders.

Background: Aortic valve stenosis is common in the elderly, with a prevalence of nearly 3% in patients aged 75 years or older. Despite the fact that sleep-related breathing disorders (SRBD) are thought to be associated with cardiac disease, little is known about their prevalence in this patient cohort. The purpose of this study was to evaluate the prevalence of SRBD in older patients with aortic valve stenosis admitted for transcatheter aortic valve implantation.

Sleep-Disordered Breathing and Coronary Artery Disease.

Coronary artery disease (CAD) is one of the most frequent diseases in industrial nations. Despite significant advances in diagnosis and therapy, CAD and its long-term consequences are important contributors to morbidity and mortality. Therefore, in addition to management of traditional CAD risk factors, there are continued efforts to evaluate other factors and comorbidities that might contribute to the development and progression of CAD.

Stenting as a rescue treatment of a pulmonary artery false aneurysm caused by swan-ganz catheterization.

Pulmonary vascular injury is a rare but life-threatening complication of Swan-Ganz catheterization. We report an 82-year old patient who underwent right heart catheterization by a balloon-tipped catheter because of suspected pulmonary hypertension. After deflation of the catheter in the wedge position, hemoptoe appeared associated with acute respiratory insufficiency requiring respiratory support by intubation and mechanical ventilation.

Postoperative care and follow-up after coronary stenting.

Background: The diagnosis and treatment of coronary heart disease have improved in recent years. Most patients can return to their everyday routine a few days after a successful percutaneous coronary intervention (PCI). How should patients be followed up after the successful implantation of a coronary stent?

Method: Selective review of the pertinent literature, including current practice guidelines and recommendations.

Impaired mobilization of CD133(+) bone marrow-derived circulating progenitor cells with an increased number of diseased coronary arteries in ischemic heart disease patients with diabetes.

Background: The influence of the number of diseased coronary arteries on the mobilization of CD133/45(+) bone marrow-derived circulating progenitor cells (BM-CPCs) in peripheral blood (PB) in patients with ischemic heart disease (IHD) was analyzed.

Methods And Results: Mobilization of CD133/45(+) BM-CPCs by flow cytometry was measured in 120 patients with coronary 1 vessel (IHD1, n=40), coronary 2 vessel (IHD2, n=40), and coronary 3 vessel disease (IHD3, n=40), and in a control group (n=40). The mobilization of CD133/45(+) BM-CPCs was significantly reduced in patients with IHD compared to the control group (P<0.

Improved mobilization of the CD34(+) and CD133(+) bone marrow-derived circulating progenitor cells by freshly isolated intracoronary bone marrow cell transplantation in patients with ischemic heart disease.

Cell therapy is a promising novel option for treatment of cardiovascular disease. Because the role of bone marrow-derived circulating progenitor cells (BM-CPCs) after cell therapy is less clear, we analyzed in this randomized, controlled study the influence of intracoronary autologous freshly isolated bone marrow cell transplantation (BMC-Tx) by using a point-of-care system on cardiac function and on the mobilization of BM-CPCs in patients with ischemic heart disease (IHD). Fifty-six patients with IHD were randomized to either receive freshly isolated BMC-Tx or a control group that did not receive cell therapy.
