Abstract

SummaryOn the 24th November 2021 the sequence of a new SARS CoV-2 viral isolate spreading rapidly in Southern Africa was announced, containing far more mutations in Spike (S) than previously reported variants. Neutralization titres of Omicron by sera from vaccinees and convalescent subjects infected with early pandemic as well as Alpha, Beta, Gamma, Delta are substantially reduced or fail to neutralize. Titres against Omicron are boosted by third vaccine doses and are high in cases both vaccinated and infected by Delta. Mutations in Omicron knock out or substantially reduce neutralization by most of a large panel of potent monoclonal antibodies and antibodies under commercial development. Omicron S has structural changes from earlier viruses, combining mutations conferring tight binding to ACE2 to unleash evolution driven by immune escape, leading to a large number of mutations in the ACE2 binding site which rebalance receptor affinity to that of early pandemic viruses.

Abstract

Introduction: Awake prone positioning (APP) might benefit patients with COVID-19 by improving oxygenation, but it is unknown whether this improvement can be sustained with serial proning episodes.Methods: We conducted a retrospective review of adults with COVID-19 admitted to one intensive care unit, in those who underwent APP and controls. Patients in both groups had type 1 respiratory failure requiring oxygen (but not initially intubated), confirmed SARS-CoV-2 PCR by nasopharyngeal swab and findings of multifocal ground-glass opacities on imaging. For the APP group, serial SpO2/FiO2 measurements were recorded after each proning episode.Results: Of 77 patients admitted, 50 (65%) were excluded because they had already been intubated. Another 7 (9%) had undergone APP prior to admission. Of the remaining 20, 10 underwent APP and 10 were controls. Patients in both groups had similar demographics, subsequent intubation and survival. Of those who underwent APP, SpO2/FiO2 was most likely to increase after the first episode (before median: 152, IQR 135-185; after: median 192, IQR 156-234, p=0.04). Half of participants (5) in the APP group were unable to tolerate more than two APP episodes.Conclusions: Most patients with COVID-19 admitted to the intensive care are not suitable for APP. Of those who are, many cannot tolerate more than two episodes. Improvements in SpO2/FiO2 secondary to APP are transient and most likely in the first episode. Our findings may explain why other studies have failed to show improvements in mortality from APP despite improvements in oxygenation. [ABSTRACT FROM AUTHOR]

22. Accelerating the evolution of SARS-CoV-2 - a risk of combining dexamethasone and tocilizumab for severe COVID-19.

Abstract

Emerging data from open-label randomized trials without placebo controls suggest potential mortality benefits for combining corticosteroids with the IL-6 receptor antagonist tocilizumab in severe COVID-19. Conversely, dual immunomodulation may weaken anti-viral responses and delay viral clearance, allowing SARS-CoV-2 to expand its population and accrue genetic diversity within individual hosts. Generating a pool of hosts with genetically diverse viral populations while introducing new selective pressures in the form of vaccination-induced immunity, could accelerate the process of antigenic drift in SARS-CoV-2. However, clinical trials to date have largely disregarded viral outcomes, and data on viral kinetics in response to immunomodulation is scarce. Co-administration of antiviral agents with immunomodulation could serve as a potential strategy to aid viral clearance and reduce the risk of genetic diversification. [ABSTRACT FROM AUTHOR]

Abstract

Aims: Most patients who receive implantable cardioverter defibrillators (ICDs) for primary prevention do not receive therapy during the lifespan of the ICD, whilst up to 50% of sudden cardiac death (SCD) occur in individuals who are considered low risk by conventional criteria. Machine learning offers a novel approach to risk stratification for ICD assignment., Methods and Results: Systematic search was performed in MEDLINE, Embase, Emcare, CINAHL, Cochrane Library, OpenGrey, MedrXiv, arXiv, Scopus, and Web of Science. Studies modelling SCD risk prediction within days to years using machine learning were eligible for inclusion. Transparency and quality of reporting (TRIPOD) and risk of bias (PROBAST) were assessed. A total of 4356 studies were screened with 11 meeting the inclusion criteria with heterogeneous populations, methods, and outcome measures preventing meta-analysis. The study size ranged from 122 to 124 097 participants. Input data sources included demographic, clinical, electrocardiogram, electrophysiological, imaging, and genetic data ranging from 4 to 72 variables per model. The most common outcome metric reported was the area under the receiver operator characteristic (n = 7) ranging between 0.71 and 0.96. In six studies comparing machine learning models and regression, machine learning improved performance in five. No studies adhered to a reporting standard. Five of the papers were at high risk of bias., Conclusion: Machine learning for SCD prediction has been under-applied and incorrectly implemented but is ripe for future investigation. It may have some incremental utility in predicting SCD over traditional models. The development of reporting standards for machine learning is required to improve the quality of evidence reporting in the field., Competing Interests: Conflict of interest: None declared., (© The Author(s) 2022.
