Background: Novel coronavirus (SARS-CoV-2) became an epidemic disease and lead to a pneumonia outbreak first in December 2019 in Wuhan, China. The symptoms related to coronavirus disease-19 (COVID-19) were different ranging from mild to severe lung injury and multi-organ failure symptoms, eventually leading to death, especially in older patients with other co-morbidities. The receptor of this virus in the human cell is angiotensin-converting enzyme 2 (ACE2).
Methods: In this paper, we aimed to perform an in silico analysis of the frequently studied variants of the ACE2 gene and determine the effects of the variants in mRNA secondary structure and binding affinity of cellular factors. Fourteen single-nucleotide polymorphisms were selected based on previous studies and investigated.
Results: All of the variants were analyzed in the RNAsnp database and three revealed a significant p-value. The spliceAid2 database prediction showed that 7 out of 14 SNPs caused an alteration in a way that only the wild or mutated form was able to bind to proteins. The latter database also reported that three SNPs produces a dual form in which different specific proteins can bind to the sequence in a specific form (either wild or mutated form).
Conclusion: Altogether, these estimations revealed the potential of variants in manipulation of the final stable form of ACE2 that can lead to different COVID-19 susceptibility.

Background: Carbapenem-Resistant Gram-Negative Bacteria, including Carbapenem-Resistant Enterobacterales (CRE) and Carbapenem-Resistant Pseudomonas aeruginosa (CRPA), are common causes of infections in intensive care units (ICUs) in Italy.
Objective: This prospective observational study evaluated the epidemiology, management, microbiological characterization, and outcomes of hospital-acquired CRE or CRPA infections treated in selected ICUs in Italy.
Methods: The study included patients with hospital-acquired infections due to CRE and CRPA treated in 20 ICUs from June 2021 to February 2023.

Animal models that accurately reflect COVID-19 are vital for understanding mechanisms of disease and advancing development of improved vaccines and therapeutics. Pigs are increasingly recognized as valuable models for human disease due to their genetic, anatomical, physiological, and immunological similarities to humans, and they present a more ethically viable alternative to non-human primates. However, pigs are not susceptible to SARS-CoV-2 infection which limits their utility as a model.

The COVID-19 pandemic has emphasized the necessity for rapid and adaptable drug screening platforms against live pathogenic viruses that require high levels of biosafety containment. Conventional antiviral testing is time-consuming and labor-intensive. Here, we outline the design and validation of a semi-automated drug-screening platform for SARS-CoV-2 that utilizes multiple liquid handlers, a stable A549 cell line expressing ACE2 and TMPRSS2 receptors, and a recombinant SARS-CoV-2 strain harboring the nano-luciferase gene.

Objective: Recently, angiotensin-converting enzyme 2 (ACE2) gene has emerged as a potential candidate gene for susceptibility to SARS-CoV-2 infection. We investigated whether ACE2 G8790A (rs2285666) polymorphism could be a genetic marker for susceptibility to COVID-19 and disease severity in Egyptian children and adolescents.
Methods: This was a prospective case-control study included 580 cases diagnosed with COVID-19, and 580 matched control children and adolescents.
