Observational Study
Rapid antigen test to identify COVID-19 infected patients with and without symptoms admitted to the Emergency Department.
Early detection of SARS-CoV-2 patients is essential to contain the pandemic and keep the hospital secure. The rapid antigen test seems to be a quick and easy diagnostic test to identify patients infected with SARS-CoV-2. To assess the possible role of the antigen test in the Emergency Department (ED) assessment of potential SARS-CoV-2 infection in both symptomatic and asymptomatic patients. ⋯ The antigen test performed in the ED, though not ideal, can improve the overall identification of infected patients. While it appears to perform well in symptomatic patients, in asymptomatic patients, although it improves their management, it seems not to be definitive.

Adaptive immune responses play critical roles in viral clearance and protection against re-infection, and SARS-CoV-2 is no exception. What is exceptional is the rapid characterization of the immune response to the virus performed by researchers during the first 20 months of the pandemic. This has given us a more detailed understanding of SARS-CoV-2 compared to many viruses that have been with us for a long time. ⋯ The pandemic has engaged scientists and the public alike, and terms such as seroprevalence, neutralizing antibodies, antibody escape and vaccine certificates have become familiar to a broad community. Here, we review key findings concerning B cell and antibody (Ab) responses to SARS-CoV-2, focusing on non-severe cases and anti-spike (S) Ab responses in particular, the latter being central to protective immunity induced by infection or vaccination. The emergence of viral variants that have acquired mutations in S acutely highlights the need for continued characterization of both emerging variants and Ab responses against these during the evolving pathogen-immune system arms race.

Review[Decision support for patient admission in case of suspicion of COVID-19].
During a pandemic situation, patients with suspected coronavirus disease (COVID-19) are also treated by emergency medical services (EMS). In order to establish an adequate procedure, a decision aid for the allocation of patients in case of suspicion of COVID-19 has been prepared for the ambulance staff as well as for the emergency physician in the Bavarian EMS. ⋯ The flowchart allows patients to be categorized in three stages, based on (vital) parameters and criteria such as risk factors and specific framework conditions. The aim is to provide emergency physicians and ambulance staff with guidance for the assessment of patients and the resulting transport decision with a suitable target clinic if necessary.

This work aimed to better understand the impact of pandemics of respiratory viruses on children with hemoglobinopathies through a comprehensive review of the literature. MEDLINE, SCIELO, LILACS, and PUBMED were used as data sources to find articles without time period restrictions. Previous observations suggest that patients with hemoglobinopathies are a group especially susceptible to the complications of viral respiratory infections, with greater morbidity and mortality related to them. ⋯ In the H1N1 pandemic, patients with hemoglobinopathies behaved as a group more susceptible to complications, with increased morbidity and mortality. However, for COVID-19, the existing data to date on these patients do not show the same clinical impact. Thus, although these children deserve attention in case of infection due to their potential risks, they seem to have a favorable evolution.

Exposure to air pollutants and illness by severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) infection can cause serious pulmonary impairment. ⋯ An association between exposure to air pollutants and hospital admission due to Sars-Cov-2 was observed with excess hospitalization and costs for the Brazilian public health system.
