From the beginning, the COVID-19 pandemic turned out to be a huge challenge and burden for medical services [1]. Currently, humanity is dealing with a new wave of the virus that has evolved and presents a new challenge, mainly due to its ability to avoid immune surveillance. Indeed, our main line of defense — vaccines — may be compromised. Omicron variants are characterized by an evolutionary force unprecedented so far. Among the several sublines that have already emerged, the BA.5 strain exhibit higher transmissibility and demonstrates a worrisome immune evasion. According to several laboratory investigations, vaccination-induced antibodies are less successful …

The single-stranded viral RNA (ssvRNA) known as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes COVID-19 can be effectively inactivated by a number of natural ribonucleic acid-based host cell defenses. One of the most important of these defenses includes the actions of a class of small non-coding RNAs (sncRNAs) known as microRNAs (miRNAs). Via base-pair complementarity miRNAs are capable of specifically targeting ssvRNA sequences such as SARS-CoV-2 promoting its inactivation and neutralization. RNA-sequencing and bioinformatics analysis indicate that multiple naturally-occurring human miRNAs have extensive complementarity to the SARS-CoV-2 ssvRNA genome. Since miRNA abundance, speciation, and complexity vary significantly …

The pathophysiology and treatment of COVID-19 have been at the forefront of medical research this past year. While great strides have been made in our knowledge of the disease, there is still much that is unknown. More than one-third of patients with COVID-19 present with symptoms involving the nervous system. The reason for this is unclear, although several theories have been postulated. In this case study, we present 3 patients with severe ulnar nerve dysfunction following treatment for COVID-19 in the intensive care unit. We discuss reasons why this may have occurred, the etiology of which is likely multifactorial. We …

Coronavirus disease 2019 (COVID-19) first emerged in Wuhan city in December 2019, and became a grave global concern due to its highly infectious nature. The Severe Acute Respiratory Coronavirus-2, with its predecessors (i.e., MERS-CoV and SARS-CoV) belong to the family of Coronaviridae. Reportedly, COVID-19 has infected 344,710,576 people around the globe and killed nearly 5,598,511 persons in the short span of two years. On November 24, 2021, B.1.1.529 strain, later named Omicron, was classified as a Variant of Concern (VOC). SARS-CoV-2 has continuously undergone a series of unprecedented mutations and evolved to exhibit varying characteristics. These mutations have largely occurred …
