Impact of the COVID-19 Pandemic on Patient Delay and Clinical Outcomes for Patients With Acute Myocardial Infarction.
It has been known that the fear of contagion during the coronavirus disease 2019 (COVID-19) creates time delays with subsequent impact on mortality in patients with acute myocardial infarction (AMI). However, difference of time delay and clinical outcome in patients with ST-segment elevation myocardial infarction (STEMI) or non-STEMI between the COVID-19 pandemic and pre-pandemic era has not been fully investigated yet in Korea. The aim of this study was to investigate the impact of COVID-19 pandemic on time delays and clinical outcome in patients with STEMI or non-STEMI compared to the same period years prior. ⋯ During the COVID-19 pandemic, there has been a considerable reduction in hospital admissions for AMI, time delay, and underuse of ACE-I/ARBs for the management of AMI, and this might be closely associated with the excess death in Korea.

Case Reports
Peritonsillar abscess caused by Prevotella bivia during home quarantine for coronavirus disease 2019: Case report.
Since late 2019, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) had rapidly spread worldwide, resulting in a pandemic. Patients with coronavirus disease 2019 (COVID-19) have difficulty in visiting clinics in person during pandemic because they might be encouraged to quarantine at home with supportive care. Peritonsillar abscess rarely coexists with COVID-19; however, patients with SARS-CoV-2 infection could get co-infections or become superinfected with other microorganisms which could cause peritonsillar abscess. We herein describe a case of peritonsillar abscess caused by Prevotella bivia that occurred as a co-infection with COVID-19 during home quarantine. ⋯ Patients with suspected peritonsillar abscess should be triaged and referred to ear, nose, throat specialists appropriately. Scoring systems, such as modified Liverpool peritonsillar abscess score or the guidelines criteria might be useful tools to triage patients. During the early phase of SARS-CoV-2 infection, administration of corticosteroids is not recommended. When adjunctive steroids are considered for peritonsillar abscess, prior to or simultaneous use of the antiviral agent remdesivir for COVID-19 might be recommended.

Randomized Controlled Trial
Evaluation of mRNA-1273 Covid-19 Vaccine in Children 6 to 11 Years of Age.
Vaccination of children to prevent coronavirus disease 2019 (Covid-19) is an urgent public health need. The safety, immunogenicity, and efficacy of the mRNA-1273 vaccine in children 6 to 11 years of age are unknown. ⋯ Two 50-μg doses of the mRNA-1273 vaccine were found to be safe and effective in inducing immune responses and preventing Covid-19 in children 6 to 11 years of age; these responses were noninferior to those in young adults. (Funded by the Biomedical Advanced Research and Development Authority and the National Institute of Allergy and Infectious Diseases; KidCOVE ClinicalTrials.gov number, NCT04796896.).

Coronavirus-2019 (COVID-19) emerged in December 2019, causing significant changes in people's social lives and other human activities. The outbreak halted educational activities throughout the world. The Nigerian experience was unique in that most people were skeptical about the pandemic's existence. ⋯ This implies that the correlation matrix for the C19PS is not an identity matrix. It was revealed that C19PS had good overall reliability (α = .896) and model fit (Root mean square error of approximation = .042, comparative fit index = .943) in a sample of Nigerian preschool practitioners. As a result, C19PS was recommended as a trustworthy tool for identifying persons who suffer from COVID-19 phobia.

Functional mutations of SARS-CoV-2: implications to viral transmission, pathogenicity and immune escape.
The pandemic of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has led to major public health challenges globally. The increasing viral lineages identified indicate that the SARS-CoV-2 genome is evolving at a rapid rate. Viral genomic mutations may cause antigenic drift or shift, which are important ways by which SARS-CoV-2 escapes the human immune system and changes its transmissibility and virulence. Herein, we summarize the functional mutations in SARS-CoV-2 genomes to characterize its adaptive evolution to inform the development of vaccination, treatment as well as control and intervention measures.
