Influence of the coronavirus 2 (SARS-Cov-2) pandemic on acute appendicitis.
Acute appendicitis (AA) is the most common abdominal surgical emergency. No specific studies have been found that evaluate the impact of the coronavirus 2 (SARS-Cov-2) pandemic on AA and its surgical management. An analysis was made on the influence of this new pathology on the clinical course of AA. ⋯ The SARS-Cov-2 pandemic influenced the time of diagnosis of appendicitis, as well as its course, and mean hospital stay. Peritonitis was more frequently seen. As a result of the significant circumstances, delaying diagnosis and treatment of AA during SARS-Cov-2 pandemic, inappropriate management of this common surgical disorder has been noticed.

Case ReportsA case presentation for positive SARS-CoV-2 RNA recurrence in a patient with a history of type 2 diabetes that had recovered from severe COVID-19.
Coronavirus disease 2019 (COVID-19) is considered to be spread primarily by people who have tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Here, we discuss a patient with severe COVID-19 and a history of type 2 diabetes who had a recurrence of positive SARS-CoV-2 ribonucleic acid (RNA) after recovering. The patient was initially discharged after two consecutive negative SARS-CoV-2 RNA tests and partially absorbed bilateral lesions on chest computed tomography (CT). ⋯ The results tested positive on the 12th, 14th, 19th, 23rd and 26th of March and negative on the 28th of March, and 6th and 12th of April. After his second discharge, he has tested negative for 5 weeks. This case highlights the importance of active surveillance of SARS-CoV-2 RNA during the follow-up period so that an infectivity assessment can be made.

To date, the recently discovered SARS-CoV-2 virus has afflicted >6.9 million people worldwide and disrupted the global economy. Development of effective vaccines or treatments for SARS-CoV-2 infection will be aided by a molecular-level understanding of SARS-CoV-2 proteins and their interactions with host cell proteins. ⋯ Our bioinformatic analyses, in combination with pre-existing experimental evidence, suggest that the SARS-CoV-2 N protein is capable of forming or regulating biomolecular condensates in vivo by interaction with RNA and key host cell proteins. We discuss multiple models, whereby the N protein of SARS-CoV-2 may harness this activity to regulate viral life cycle and host cell response to viral infection.

The SARS-CoV-2 virus causing COVID-19 binds human angiotensin-converting enzyme 2 (ACE2) receptors in human tissues. ACE2 expression may be associated with COVID-19 infection and mortality rates. Routinely prescribed drugs that up- or down-regulate ACE2 expression are, therefore, of critical research interest as agents that might promote or reduce risk of COVID-19 infection in a susceptible population. ⋯ This systematic review will identify drug therapies that may increase or decrease ACE2 expression. This might identify medications increasing risk of COVID-19 transmission, or as targets for intervention in mitigating transmission.
