Determination of positive end-expiratory pressure in COVID-19-related acute respiratory distress syndrome: A systematic review.

Background: The impact of high positive end-expiratory pressure (PEEP) ventilation and the optimization of PEEP titration in COVID-19-induced acute respiratory distress syndrome (ARDS) continues to be a subject of debate. In this systematic review, we investigated the effects of varying PEEP settings on patients with severe ARDS primarily resulting from COVID-19 (C-ARDS).

Objectives: Does higher or lower PEEP improve the outcomes in COVID-19 ARDS? Does individually titrated PEEP lead to better outcomes compared with PEEP set by standardised (low and high ARDS network PEEP tables) approaches? Does the individually set PEEP (best PEEP) differ from PEEP set according to the standardised approaches (low and high ARDS network PEEP tables)?

Design: Systematic review of observational studies without metaanalysis.

The SARS-CoV-2 Delta-Omicron Recombinant Lineage (XD) Exhibits Immune-Escape Properties Similar to the Omicron (BA.1) Variant.

Recently, a recombinant SARS-CoV-2 lineage, XD, emerged that harbors a spike gene that is largely derived from the Omicron variant BA.1 in the genetic background of the Delta variant. This finding raised concerns that the recombinant virus might exhibit altered biological properties as compared to the parental viruses and might pose an elevated threat to human health.

Renaissance of glucocorticoids in critical care in the era of COVID-19: ten urging questions.

The 40-year-old experience with glucocorticosteroids (GCs) in the context of severe infections is complex and troublesome. Recently, however, a clear indication for GCs in severe COVID-19 has been established. This may constitute a harbinger of a wider use of GCs in critical illnesses.

COVID-19 Intensive Care-Evaluation of Public Information Sources and Current Standards of Care in German Intensive Care Units: A Cross Sectional Online Survey on Intensive Care Staff in Germany.

: In February 2021, the first formal evidence and consensus-based (S3) guidelines for the inpatient treatment of patients with COVID-19 were published in Germany and have been updated twice during 2021. The aim of the present study is to re-evaluate the dissemination pathways and strategies for ICU staff (first evaluation in December 2020 when previous versions of consensus-based guidelines (S2k) were published) and question selected aspects of guideline adherence of standard care for patients with COVID-19 in the ICU. We conducted an anonymous online survey among German intensive care staff from 11 October 2021 to 11 November 2021.

Early spontaneous breathing for acute respiratory distress syndrome in individuals with COVID-19.

Background: Acute respiratory distress syndrome (ARDS) represents the most severe course of COVID-19 (caused by the SARS-CoV-2 virus), usually resulting in a prolonged stay in an intensive care unit (ICU) and high mortality rates. Despite the fact that most affected individuals need invasive mechanical ventilation (IMV), evidence on specific ventilation strategies for ARDS caused by COVID-19 is scarce. Spontaneous breathing during IMV is part of a therapeutic concept comprising light levels of sedation and the avoidance of neuromuscular blocking agents (NMBA).

A Comparison and Evaluation of International Guidelines on the Treatment of Severe SARS-CoV-2 Infection.

Background: When the SARS-CoV-2 pandemic began, no uniform treatment and care strategies for critically ill COVID-19 patients were yet available. National and international treatment recommendations were formulated under time pressure, initially on the basis of indirect evidence from the treatment of similar diseases. In this article, we give an overview of the content, currency, and methodological quality of the existing national and international guidelines, with special attention to the care of critically ill patients.

Case Report: Interferon- γ Rescues Monocytic Human Leukocyte Antigen Receptor (mHLA-DR) Function in a COVID-19 Patient With ARDS and Superinfection With Multiple MDR 4MRGN Bacterial Strains.

Background: CD14+ monocytes present antigens to adaptive immune cells monocytic human leukocyte antigen receptor (mHLA-DR), which is described as an immunological synapse. Reduced levels of mHLA-DR can display an acquired immune defect, which is often found in sepsis and predisposes for secondary infections and fatal outcomes. Monocytic HLA-DR expression is reliably induced by interferon- γ (IFNγ) therapy.

[COVID-19 pandemic: preferences and barriers for dissemination of evidence syntheses : Survey of intensive care personnel in Germany].

Background: In the context of COVID-19, the German CEOsys project (COVID-19 Evidenz Ökosystem, www.covid-evidenz.de ) identifies, evaluates and summarizes the results of scientific studies to obtain evidence on this disease.

A Nationwide Cross-Sectional Online Survey on the Treatment of COVID-19-ARDS: High Variance in Standard of Care in German ICUs.

Introduction: Coronavirus disease (COVID-19) has recently dominated scientific literature. Incomplete understanding and a lack of data concerning the pathophysiology, epidemiology, and optimal treatment of the disease has resulted in conflicting recommendations. Adherence to existing guidelines and actual treatment strategies have thus far not been studied systematically.

Targeted Minimal Staff-to-Patient Ratios Are Unachievable - A Nationwide Survey in German ICUs During the COVID-19 Pandemic.

Introduction Adequate staffing in the intensive care units (ICUs) is the most important factor to provide optimal care and ensure favorable outcomes in critically ill patients. Recently, the need for ICU beds has reached unprecedented levels and the management and treatment of critically ill patients has been in focus. The aim of the study was to assess the targeted and actual nurse-to-patient (NPR) and physician-to-patient ratios (PPR) regarding patients with and without COVID-19.

Infection control, prophylactic antibiotics, and testing for SARS-CoV-2 and PPE on German intensive care units: results from a national mixed methods survey.

Recommendations on hygiene measures, personal protective equipment (PPE), isolation, and antibiotic prophylaxis were developed during the coronavirus 2019 disease (COVID-19) pandemic and have been revised several times to date. Some of the underlying literature indicates a large evidence gap. We suspect that this leads to a large variance of measures on German intensive care units (ICU).

Prevalence and risk factors of potentially malignant disorders of the mucosa in the general population: Mucosa lesions a general health problem?

Aim: Oral cancer mostly develops from oral mucosa regions with morphological alterations transforming malignant. These visible precancerous mucosa lesions are named potentially malignant disorders (PMD). We aimed to analyze the prevalence of PMD and its risk factors for PMD in a population-based sample in Northern Germany.
