Acute pulmonary embolism with and without hemodynamic instability (2003-2022): A Swiss nationwide epidemiological study.

Background: Data on the epidemiological burden of acute pulmonary embolism (PE) in Switzerland is unavailable. Knowledge gaps remain on trends in PE-related comorbidities, PE severity, and length of in-hospital stay (LOS) at a nationwide level.

Methods: We used nationwide, patient-level data including all patients aged 15 years or older hospitalized for PE in Switzerland from 2003 to 2022, amounting to N=180,600.

Intraoperative haemodynamic monitoring and management of adults having non-cardiac surgery: Guidelines of the German Society of Anaesthesiology and Intensive Care Medicine in collaboration with the German Association of the Scientific Medical Societies.

Haemodynamic monitoring and management are cornerstones of perioperative care. The goal of haemodynamic management is to maintain organ function by ensuring adequate perfusion pressure, blood flow, and oxygen delivery. We here present guidelines on "Intraoperative haemodynamic monitoring and management of adults having non-cardiac surgery" that were prepared by 18 experts on behalf of the German Society of Anaesthesiology and Intensive Care Medicine (Deutsche Gesellschaft für Anästhesiologie und lntensivmedizin; DGAI).

Extravascular lung water levels are associated with mortality: a systematic review and meta-analysis.

Background: The prognostic value of extravascular lung water (EVLW) measured by transpulmonary thermodilution (TPTD) in critically ill patients is debated. We performed a systematic review and meta-analysis of studies assessing the effects of TPTD-estimated EVLW on mortality in critically ill patients.

Methods: Cohort studies published in English from Embase, MEDLINE, and the Cochrane Database of Systematic Reviews from 1960 to 1 June 2021 were systematically searched.

Systemic acidemia impairs cardiac function in critically Ill patients.

Background: Acidemia, is associated with reduced cardiac function in animals, but no studies showing an effect of acidemia on cardiac function in humans are reported. In the present study, we examined the effect of acidemia on cardiac function assessed with transpulmonary thermodilution technique with integrated pulse contour analysis (Pulse Contour Cardiac Output, PiCCO™) in a large cohort of critically ill patients.

Methods: This was a prospective multicenter observational cross-sectional study of 297 patients from 6 intensive care units in London, England selected from all patients admitted consecutively between May 2018 and March 2019.

Investigation of superspreading COVID-19 outbreak events in meat and poultry processing plants in Germany: A cross-sectional study.

Since May 2020, several COVID-19 outbreaks have occurred in the German meat industry despite various protective measures, and temperature and ventilation conditions were considered as possible high-risk factors. This cross-sectional study examined meat and poultry plants to assess possible risk factors. Companies completed a self-administered questionnaire on the work environment and protective measures taken to prevent SARS-CoV-2 infection.

B-Lines for the assessment of extravascular lung water: Just focused or semi-quantitative?

Background: B-lines as typical artefacts of lung ultrasound are considered as surrogate measurement for extravascular lung water. However, B-lines develop in the sub-pleural space and do not allow assessment of the whole lung. Here, we present data from the first observational multi-centre study focusing on the correlation between a B-lines score and extravascular lung water in critically ill patients suffering from a variety of diseases.

IL-17A/F in Leishmania major-resistant C57BL/6 mice.

Proinflammatory IL-17 plays an important role in various diseases and defence against extracellular microorganisms. Healing of leishmaniasis is promoted by Th1/Tc1 cells, whereas Th2/Treg are associated with worsened disease outcome. In addition, high expression of IL-17A in Leishmania-susceptible BALB/c and artificial overexpression of IL-17A in T cells in resistant C57BL/6 mice worsened disease outcome.

Pulmonary embolism.

Pulmonary embolism (PE) is caused by emboli, which have originated from venous thrombi, travelling to and occluding the arteries of the lung. PE is the most dangerous form of venous thromboembolism, and undiagnosed or untreated PE can be fatal. Acute PE is associated with right ventricular dysfunction, which can lead to arrhythmia, haemodynamic collapse and shock.

Chronic thromboembolic pulmonary hypertension from the perspective of patients with pulmonary embolism.

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare but feared long-term complication of acute pulmonary embolism (PE), although CTEPH may occur in patients with no history of symptomatic venous thromboembolism. It represents the most severe presentation of the so-called 'post-PE syndrome', a phenomenon of permanent functional limitations after PE caused by deconditioning after PE or ventilatory or circulatory impairment as a result of unresolved pulmonary artery thrombi. Because the post-PE syndrome may occur in up to 50% of PE survivors, and CTEPH tends to have an insidious and non-specific clinical presentation, CTEPH is often not diagnosed or diagnosed after a very long delay.

Pharmacokinetics of dabigatran etexilate and rivaroxaban in patients with short bowel syndrome requiring parenteral nutrition: The PDER PAN study.

Background And Aims: Patients on parenteral nutrition for short bowel syndrome (SBS) have a high risk of thrombotic complications and are often treated with parenteral anticoagulation. Direct oral anticoagulants are absorbed proximally in the digestive tract and may represent alternative regimens in selected SBS patients. In our pilot study, we provided pharmacokinetics parameters of dabigatran etexilate and rivaroxaban in this setting and compared peak (Cmax), trough (Ctrough) concentrations, and areas-under-the-concentration-time-curve (AUC) to reference values retrieved from phase I-III studies.

Insufficient generation of Th17 cells in IL-23p19-deficient BALB/c mice protects against progressive cutaneous leishmaniasis.

Healing of leishmaniasis-a parasitic skin disease-is associated with high levels of secreted interferon (IFN)γ and IL-12 in resistant C57BL/6 mice and humans. Susceptible BALB/c mice predominantly react with a Th17/Th2/Treg-related immune response and finally succumb to infection. Previously, we showed that BALB/c IL-17A mice are protected against Leishmania (L.

Septic cardiomyopathy: evidence for a reduced force-generating capacity of human atrial myocardium in acute infective endocarditis.

Background: This study analyzes the myocardial force-generating capacity in infective endocarditis (IE) using an experimental model of isolated human atrial myocardium. , it is difficult to decide whether or not alterations in myocardial contractile behavior are due to secondary effects associated with infection such as an altered heart rate, alterations of preload and afterload resulting from valvular defects, and altered humoral processes. Our model using isolated human myocardium, in contrast, guarantees exactly defined experimental conditions with respect to preload, afterload, and contraction frequency, thus not only preventing confounding by determinants of contractility but also excluding effects of other factors associated with sepsis, hemodynamics, humoral influences, temperature, and medical treatment.

Portal vein leiomyosarcoma: a case report and review of the literature.

Background: Leiomyosarcoma of vascular smooth muscle is a very rare entity. A fair number of cases of vascular leiomyosarcomas have been reported, and the vast majority of these tumors arose from the inferior vena cava.

Case Presentation: We report the case of a 71-year-old female patient who presented with recurrent upper abdominal pain.

Self-adjuvanted mRNA vaccination in advanced prostate cancer patients: a first-in-man phase I/IIa study.

Background: CV9103 is a prostate-cancer vaccine containing self-adjuvanted mRNA (RNActive®) encoding the antigens PSA, PSCA, PSMA, and STEAP1. This phase I/IIa study evaluated safety and immunogenicity of CV9103 in patients with advanced castration-resistant prostate-cancer.

Methods: 44 Patients received up to 5 intra-dermal vaccinations.

Differentiation of Monocyte Derived Dendritic Cells in End Stage Renal Disease is Skewed Towards Accelerated Maturation.

Background: Dendritic cells (DC) play an important role in the induction of immune responses. Patients with end stage renal disease (ESRD) suffer from chronic inflammation, leading to a secondary, uremic immunodeficiency associated with alterations in monocyte subpopulations with increased proinflammatory capacities.

Objectives: The aim of this study was to examine, under isolated conditions, whether alterations in monocyte subpopulations may affect in vitro maturation of dendritic cells (DC) in patients with ESRD, thus allowing us to draw conclusions for the situation in vivo.

Transpulmonary cardiac output measurement in a rat model of cardiac arrest and CPR: impact of vascular access.

Objective: The present study investigated the impact of the vascular access site for cardiac output (CO) measurement by thermodilution on survival and neurohistopathological injury in a rat model of cardiac arrest (CA) and cardiopulmonary resuscitation (CPR). Secondary the influence of the vascular access site on cardiac output measurements was examined.

Methods: Rats underwent asphyxial CA and CPR.

Investigation of the regeneration potential of the recurrent laryngeal nerve (RLN) after compression injury, using neuromonitoring.

Introduction: The aim of this study was to investigate the regeneration potential of RLN after the compression of the nerve, without disrupting its continuity, using neuromonitoring.

Methods: In the first operation, the RLN and nervus vagus of adult Goettingen minipigs were dissected free, and the neuromonitoring parameters (amplitude, threshold and lag time of signal) were measured. Injury of the RLN was induced using a "bulldog" clamp.

Coincidence of nonpuerperal mastitis and noninflammatory breast cancer.

Background: Nonpuerperal mastitis may mimic breast cancer but the incidence of noninflammatory cancer among such patients is unknown.

Aim: To estimate the risk of breast cancer in patients with nonpuerperal mastitis within 12 months of treatment.

Study Design: Two hundred seventy-seven patients with nonpuerperal breast inflammation were prospectively screened for breast cancer within 1 year after mastitis was diagnosed.

Hepatic manifestation of hemolytic uremic syndrome in an allogeneic bone marrow transplant recipient.

A 33-year-old woman presented 42 days after allogeneic bone marrow transplantation for acute monocytic leukemia (AML, FAB M5) with persistent thrombocytopenia, acute renal failure and Coombs negative hemolytic anemia. In the absence of the disseminated intravascular coagulation the diagnosis of hemolytic uremic syndrome due to immunosuppression with cyclosporin A was supposed. Because cessation of cyclosporin A and therapeutic infusions of fresh frozen plasma had failed, plasmaseparation therapy was started on day 79 after bone marrow transplantation.
