SARS-CoV-2 BA.5 vaccine breakthrough risk and severity compared with BA.2: a case-case and cohort study using Electronic Health Records in Portugal

Background In a context of multiple Omicron lineages circulation, it is relevant to clarify the effect of vaccination and previous infections on the risk of infection and severe post-infection outcomes. see more

Source : https://doi.org/10.1101/2022.07.25.22277996


Interpretation: This study shows that the SARS-CoV-2 Omicron BA.5 lineage is associated with higher odds of reinfection compared with Omicron BA.2, regardless of the vaccination status.

Breakthrough SARS-CoV-2 infections in immune mediated disease patients undergoing B cell depleting therapy: A retrospective cohort analysis - PubMed

doi: 10.1002/art.42287. Online ahead of print. 1 Department of Rheumatic and Immunologic Diseases, Cleveland Clinic. 2 Mellen Center for Multiple Sclerosis Treatment and Research, Cleveland Clinic. 3 Department of Dermatology, ..... see more

Source : https://pubmed.ncbi.nlm.nih.gov/35791921/


Conclusions: IMIDs patients on BCDT regardless of vaccine status appear vulnerable to infection with SARS-CoV-2 and are frequently associated with severe outcomes. Outpatient use of anti-SARS-CoV-2 monoclonal antibody therapy appeared to be associated with enhanced clinical outcomes.

Association of periodic fasting with lower severity of COVID-19 outcomes in the SARS-CoV-2 prevaccine era: an observational cohort from the INSPIRE registry

Objectives Intermittent fasting boosts some host defence mechanisms while modulating the inflammatory response. Lower-frequency fasting is associated with greater survival and lower risk from COVID-19-related comorbidities. This study evaluated associations ..... see more

Source : https://nutrition.bmj.com/content/early/2022/06/30/bmjnph-2022-000462


Conclusions: Routine periodic fasting was associated with a lower risk of hospitalisation or mortality in patients with COVID-19. Fasting may be a complementary therapy to vaccination that could provide immune support and hyperinflammation control during and beyond the pandemic.

Poxviruses package viral redox proteins in lateral bodies and modulate the host oxidative response

Author summary Vaccinia virus is the prototype member of the Poxviridae family, whose members include monkeypox and variola virus, the causative agent of smallpox. All poxvirus particles, including vaccinia, are ..... see more

Source : https://doi.org/10.1371/journal.ppat.1010614


Using targeted repression and/or deletion viruses we found that deletion of individual LB-redox proteins was insufficient for host redox modulation suggesting there may be functional redundancy. In addition to defining the spatial proteotype of VACV LBs, these findings implicate poxvirus redox proteins as potential modulators of host oxidative...

Transient Global Amnesia Related to the Third Coronavirus Disease-19 (COVID-19) Vaccination

We present a case report of transient global amnesia (TGA) after vaccinating the third dose of coronavirus disease-19 (COVID-19). A 65-year-old Japanese woman presented with TGA after her third vaccination, ..... see more

Source : https://www.cureus.com/articles/104384-transient-global-amnesia-related-to-the-third-coronavirus-disease-19-covid-19-vaccination



Conclusions: We experienced the case with TGA after the third COVID-19 vaccination. A 65-year-old Japanese woman showed TGA after her third vaccination, which spontaneously resolved. This article aims to facilitate the clinicians’ understanding that TGA could occur after vaccination in the COVID-19 global outbreak. We should be careful of...

Interpretation: Vaccination against COVID-19 in children aged 5–11 years in Italy showed a lower effectiveness in preventing SARS-CoV-2 infection and severe COVID-19 than in individuals aged 12 years and older. Effectiveness against infection appears to decrease after completion of the current primary vaccination cycle.

Admission Hyperglycemia as a Predictor of COVID-19 Pneumonia, Cytokine Release Syndrome Progression, and Clinical Outcomes in a Tertiary Care Hospital

Introduction Diabetes and coronavirus disease 2019 (COVID-19) are interrelated. The presence of hyperglycemia per se during COVID-19 infection regardless of diabetes status has been associated with poor prognosis and increased ..... see more

Conclusions: Admission hyperglycemia was associated with an increased risk of progression to critical condition in patients hospitalized with COVID-19 independent of the history of diabetes. Therefore, it should not be overlooked but instead should be detected and appropriately treated to improve outcomes. In addition, post-COVID-19 care should...

Acute and post-acute COVID-19 presentations in athletes: a systematic review and meta-analysis

Objective To describe acute/postacute COVID-19 presentations in athletes. Design Systematic review and meta-analysis. Data sources The search was conducted in four databases (MEDLINE, EMBASE, SCOPUS, SPORTDiscus) and restricted to studies ..... see more

Source : https://dx.doi.org/10.1136/bjsports-2022-105583


Conclusion: This broad characterisation of COVID-19 presentations in athletes indicates that ~94% exhibited mild or no acute symptoms. The available evidence did not confirm a causal relationship between COVID-19 and myocardial involvement. A small proportion of athletes experienced persistent symptoms while recovering from infection, which...

Homogeneous surrogate virus neutralization assay to rapidly assess neutralization activity of anti-SARS-CoV-2 antibodies - Nature Communications

The results obtained with our assay and other neutralization assays are comparable but with significantly shorter preparation and run time for Neu-SATiN. As the assay is modular, we further demonstrate that Neu-SATiN enables rapid assessment of the effectiveness of vaccines and level of protection against existing SARS-CoV-2 variants of concern...

Conclusions: These preliminary findings suggest that post-acute sequelae of SARS-CoV-2 vary in frequency and duration with relation to premorbid history and that these conditions affect functional domains and patients’ ability to return to work. Longitudinal research with larger cohorts is needed to characterize PASC and to optimize care,...

Conclusions and Relevance: This cohort study of SARS-CoV-2 exposure in utero found preliminary evidence that maternal SARS-CoV-2 may be associated with neurodevelopmental sequelae in some offspring. Prospective studies with longer follow-up duration will be required to exclude confounding and confirm these associations.
