Relative effectiveness of the second booster COVID-19 vaccines against laboratory confirmed SARS-CoV-2 infection in healthcare workers: VEBIS HCW VE cohort study (1 October 2022-2 May 2023).

Introduction: Repeated COVID-19 booster vaccination was recommended in healthcare workers (HCWs) to maintain protection. We measured the relative vaccine effectiveness (rVE) of the second booster dose of COVID-19 vaccine compared to the first booster, against laboratory-confirmed SARS-CoV-2 infection in HCWs.

Methods: In a prospective cohort study among HCWs from 12 European hospitals, we collected nasopharyngeal or saliva samples at enrolment and during weekly/fortnightly follow-up between October 2022 and May 2023.

Incidence of SARS-CoV-2 Infection Among European Healthcare Workers and Effectiveness of the First Booster COVID-19 Vaccine, VEBIS HCW Observational Cohort Study, May 2021-May 2023.

European countries have included healthcare workers (HCWs) among priority groups for COVID-19 vaccination. We established a multi-country hospital network to measure the SARS-CoV-2 incidence and effectiveness of COVID-19 vaccines among HCWs against laboratory-confirmed SARS-CoV-2 infection. HCWs from 19 hospitals in 10 countries participated in a dynamic prospective cohort study, providing samples for SARS-CoV-2 testing at enrolment and during weekly/fortnightly follow-up.

Comparison of Fentanyl, Ketamine, and Lidocaine Combined with Propofol Anesthesia in Patients with Crohn Disease Undergoing Colonoscopy.

BACKGROUND Colonoscopy is the predominant invasive procedure for Crohn disease (CD) patients. Opioids and propofol carry risks of respiratory and cardiovascular complications. This study aimed to evaluate whether substituting fentanyl with ketamine or lidocaine could diminish propofol usage and minimize adverse events.

Personalized mechanical ventilation guided by ultrasound in patients with acute respiratory distress syndrome (PEGASUS): study protocol for an international randomized clinical trial.

Background: Acute respiratory distress syndrome (ARDS) is a frequent cause of hypoxemic respiratory failure with a mortality rate of approximately 30%. Identifying ARDS subphenotypes based on "focal" or "non-focal" lung morphology has the potential to better target mechanical ventilation strategies of individual patients. However, classifying morphology through chest radiography or computed tomography is either inaccurate or impractical.

Mechanical ventilation during extracorporeal membrane oxygenation support - New trends and continuing challenges.

Background: The impact of mechanical ventilation on the survival of patients supported with veno-venous extracorporeal membrane oxygenation (V-V ECMO) due to severe acute respiratory distress syndrome (ARDS) remains still a focus of research.

Methods: Recent guidelines, randomized trials, and registry data underscore the importance of lung-protective ventilation during respiratory and cardiac support on ECMO.

Results: This approach includes decreasing mechanical power delivery by reducing tidal volume and driving pressure as much as possible, using low or very low respiratory rate, and a personalized approach to positive-end expiratory pressure (PEEP) setting.

Effects of adding the second drainage cannula in severely hypoxemic patients supported with VV ECMO due to COVID-19-associated ARDS.

Background: Extracorporeal membrane oxygenation (ECMO) is a recognized method of support in patients with severe and refractory acute respiratory distress syndrome (ARDS) caused by SARS-CoV-2 infection. While veno-venous (VV) ECMO is the most common type, some patients with severe hypoxemia may require modifications to the ECMO circuit. In this study, we aimed to investigate the effects of adding a second drainage cannula to the circuit in patients with refractory hypoxemia, on their gas exchange, mechanical ventilation, ECMO settings, and clinical outcomes.

Efficacy and adverse events profile of videolaryngoscopy in critically ill patients: subanalysis of the INTUBE study.

Background: Tracheal intubation is a high-risk procedure in the critically ill, with increased intubation failure rates and a high risk of other adverse events. Videolaryngoscopy might improve intubation outcomes in this population, but evidence remains conflicting, and its impact on adverse event rates is debated.

Methods: This is a subanalysis of a large international prospective cohort of critically ill patients (INTUBE Study) performed from 1 October 2018 to 31 July 2019 and involving 197 sites from 29 countries across five continents.

Severe course of COVID-19 in pregnant woman and newborn's alloimmune thrombocytopenia - case study and review of the literature.

So far, little is known about the impact of the coronavirus disease 2019 (COVID-19) on pregnancy and data is often inconsistent. Even less information has been published on the management of severe courses of COVID-19 in pregnant women. By writing this article, we aim to share our experience in the treatment of pregnant woman critically ill with COVID-19 and newborn's condition, FNAIT (Fetal and neonatal alloimmune thrombocytopenia), as well as literature review of this disease.

SepsEast Registry indicates high mortality associated with COVID-19 caused acute respiratory failure in Central-Eastern European intensive care units.

The coronavirus disease (COVID-19) pandemic caused unprecedented research activity all around the world but publications from Central-Eastern European countries remain scarce. Therefore, our aim was to characterise the features of the pandemic in the intensive care units (ICUs) among members of the SepsEast (Central-Eastern European Sepsis Forum) initiative. We conducted a retrospective, international, multicentre study between March 2020 and February 2021.

Peri-intubation Cardiovascular Collapse in Patients Who Are Critically Ill: Insights from the INTUBE Study.

Cardiovascular instability/collapse is a common peri-intubation event in patients who are critically ill. To identify potentially modifiable variables associated with peri-intubation cardiovascular instability/collapse (i.e.

Near-infrared photobiomodulation of blood reversibly inhibits platelet reactivity and reduces hemolysis.

Photobiomodulation (PBM) in the red/near-infrared (R/NIR) spectral range has become widely recognized due to its anti-inflammatory and cytoprotective potential. We aimed to assess the effects of blood PBM on platelets function and hemolysis in an in vitro setting. Porcine blood samples were separated into four aliquots for this study, one of which served as a control, while the other three were subjected to three different NIR PBM dosages.

Flow-controlled ventilation - a new and promising method of ventilation presented with a review of the literature.

Substantial efforts have been undertaken to identify and minimise factors responsible for the development of ventilator-induced lung injury. A novel approach to this problem addresses energy dissipated in lung tissue during the breathing cycle as one of the key problems. Flow-controlled ventilation is a new modality of mechanical ventilation based on a constant flow during both inspiration and expiration.

Transition from Simple V-V to V-A and Hybrid ECMO Configurations in COVID-19 ARDS.

In SARS-CoV-2 patients with severe acute respiratory distress syndrome (ARDS), Veno-Venous Extracorporeal Membrane Oxygenation (V-V ECMO) was shown to provide valuable treatment with reasonable survival in large multi-centre investigations. However, in some patients, conversion to modified ECMO support forms may be needed. In this single-centre retrospective registry, all consecutive patients receiving V-V ECMO between 1 March 2020 to 1 May 2021 were included and analysed.

First lung transplantation as a treatment of a patient supported with extracorporeal membrane oxygenation (ECMO) after COVID-19 in Poland.

A 44-year-old male with no history of underlying diseases was referred to academic hospital due to ARDS with confirmed SARSCoV-2 infection after 7 days of mechanical ventilation. Veno-venous (VV) extracorporeal membrane oxygenation (ECMO) was initiated as no improvement was noted in prone position. Mechanical ventilation was continued with TV of 3-4 mL/kg.

Intubation Practices and Adverse Peri-intubation Events in Critically Ill Patients From 29 Countries.

Importance: Tracheal intubation is one of the most commonly performed and high-risk interventions in critically ill patients. Limited information is available on adverse peri-intubation events.

Objective: To evaluate the incidence and nature of adverse peri-intubation events and to assess current practice of intubation in critically ill patients.

Unfractionated Heparin Versus Subcutaneous Nadroparin in Adults Supported With Venovenous Extracorporeal Membrane Oxygenation: a Retrospective, Multicenter Study.

Extracorporeal membrane oxygenation (ECMO) requires constant management of coagulation. Whereas unfractionated heparin remains the anticoagulant of choice, experienced centers report high bleeding rates. Biocompatibility of the extracorporeal circuit enables management of anticoagulation with subcutaneous low-molecular-weight heparins only.

Methods And Results: We studied 154 patients with coronary artery disease (CAD) and 154 subjects free of CAD matched for age, obesity, and current smoking.

Psychiatrists and occupational burnout syndrome - a phenomenon, a problem, a threat?

The aim of this work is to present the results of research on occupational burnout in a group of psychiatrists. The electronic databases and empirical publications from 2000-2017 were searched. In order to identify reports that met the selection criteria, the papers was critically assessed.

Continuous renal replacement therapy during extracorporeal membrane oxygenation in patients treated in medical intensive care unit: technical considerations.

Extracorporeal membrane oxygenation (ECMO) is used as a salvage therapy in refractory acute respiratory distress syndrome (ARDS). Although technological progress in the ECMO systems improved the survival rate, prognosis is still significantly worsened by acute kidney injury (AKI), particularly if renal replacement therapy (RRT) is required. There are no exact guidelines recommending which techniques of ECMO and continuous RRT (CRRT) should be used for management of AKI coexisting with respiratory or circulatory failure, and how to combine them.
