Introduction: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is one of the current public health care challenges. The main strategy adopted to prevent the spread of infection is the rapid identification of COVID-19-positive subjects. The aim of this study was to compare the performance of Lumipulse® antigen immunoassay with the real-time RT-PCR, the gold standard for the diagnosis of SARS-CoV-2 infection, in a strictly selected asymptomatic population.
Materials And Methods: A total of 392 consecutive oro-nasopharyngeal swabs were collected from patients with no symptoms related to COVID-19 at the Emergency Department of AORN Sant'Anna e San Sebastiano, Caserta, Italy to evaluate the analytical performance of Lumipulse® SARS-CoV-2 antigen compared to qualitative real-time RT-PCR in asymptomatic patients.
Results: Lumipulse® SARS-CoV-2 antigen assay shows an overall agreement rate of 97% with a sensitivity of 96% and a specificity of 98%, with a PPV and NPV of 97%. The sensitivity varies according to the cycle threshold (C )-value reaching 100% and 86% with 15 < C < 25 and C ≥ 25, respectively. The ROC analysis yielded an AUC value of 0.98, suggesting that the antigen test may accurately detect SARS-CoV-2.
Conclusion: Our data showed that Lumipulse® SARS-CoV-2 antigen assay might be an efficient tool in the identification and limitation of SARS-CoV-2 transmission in large asymptomatic populations.

The COVID-19 pandemic posed a threat to global society. Delta and Omicron are concerning variants due to the risk of increasing human-to-human transmissibility and immune evasion. This study aims to evaluate the binding ability of these variants toward the angiotensin-converting enzyme 2 receptor and antibodies using a computational approach.

The present study explores the conformational dynamics of the membrane protein of Middle East Respiratory Syndrome Coronavirus (MERS-CoV) within the Endoplasmic Reticulum-Golgi Intermediate Compartment (ERGIC) complex using an all-atomistic molecular dynamics simulation approach. Significant structural changes were observed in the N-terminal, C-terminal, transmembrane, and beta-sheet sandwich domains of the MERS-CoV membrane protein. This study also highlights the structural similarities between the MERS-CoV and the SARS-CoV-2 membrane proteins, particularly in how both exhibit a distinct kink in the transmembrane helix caused by aromatic residue-lipid interactions.

Background: The Omicron variant of SARS-CoV-2 emerged as a new variant of concern, characterized by high transmissibility and lower severity compared with previous variants, and became the majority variant in the sixth wave in Spain. This study aims to assess the impact of SARS-CoV-2 infection on liver transplant recipients (LTRs) during 2023 in the population of Cantabria.
Methods: The study included 295 LTRs undergoing follow-up at the Liver Transplant Unit of the Marqués de Valdecilla University Hospital.
