Observational Study
Factors Associated with Post-Acute Sequelae of SARS-CoV-2 (PASC) After Diagnosis of Symptomatic COVID-19 in the Inpatient and Outpatient Setting in a Diverse Cohort.
The incidence of persistent clinical symptoms and risk factors in Post-Acute Sequelae of SARS-CoV-2 (PASC) in diverse US cohorts is unclear. While there are a disproportionate share of COVID-19 deaths in older patients, ethnic minorities, and socially disadvantaged populations in the USA, little information is available on the association of these factors and PASC. ⋯ Three in ten survivors with COVID-19 developed a subset of symptoms associated with PASC in our cohort. While ethnic minorities, older age, and social disadvantage are associated with worse acute COVID-19 infection and greater risk of death, our study found no association between these factors and PASC.

Caring for patients with COVID-19 has resulted in a considerable strain on hospital capacity. One strategy to mitigate crowding is the use of ED-based observation units to care for patients who may have otherwise required hospitalization. We sought to create a COVID-19 Observation Protocol for our ED Observation Unit (EDOU) for patients with mild to moderate COVID-19 to allow emergency physicians (EP) to gather more data for or against admission and intervene in a timely manner to prevent clinical deterioration. ⋯ An ED observation protocol can be successfully created and implemented for COVID-19 which allows the EP to determine which patients warrant hospitalization. Meeting protocol criteria results in an acceptable admission rate.

At global level, the pandemic coronavirus disease 2019 (COVID-19) is known to be caused by an etiologic agent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Numerous evidence and propositions have emerged on the molecular and cellular attributes that cause COVID-19. ⋯ In this direction, preclinical and clinical data on the comorbidities in the case of mitochondrial defective disease and COVID-19 are not available. The authors propose that patients harboring primary mitochondrial disease and secondary mitochondrial dysfunction will display a higher severity and death rate compared to healthy mitochondria harboring patients.

Observational Study
SARS-CoV-2 Antibody Prevalence in the Portuguese Municipality of Vila Nova de Gaia after the First Wave of the Pandemic.
Assessment of SARS-CoV-2 seroprevalence may detect the real spread of the virus because antibody data can provide a long-lasting measure of infection. Existing serological studies in Portugal have tested new serology methods, albeit with small sample sizes and a lack the focus on geographical regions with a high rate of infection cases. The aim of this study was to estimate the serological prevalence of SARS-CoV-2 in Vila Nova de Gaia, the most populous municipality in the north of Portugal and one of those most affected during the first pandemic wave. ⋯ This was the first study to estimate the serological prevalence of SARS-CoV-2 in one of the most populous municipalities in Portugal, representing the first step in the development of an epidemiological surveillance system in Portugal, which can help to improve the diagnosis of COVID-19.

A cross-section observational study on the seroprevalence of antibodies to COVID-19 in patients receiving opiate agonist treatment.
The HSE National Drug Treatment Centre is an inner city drug treatment centre in Dublin which provides opiate agonist treatment (OAT) to approximately 565 patients, many of whom have complex care needs. ⋯ These findings indicate (a) possible low level of exposure to COVID-19 among this patient cohort or (b) that those patients who have been exposed have not developed or maintained detectable antibody levels, nor developed symptoms of the disease. Public health measures could explain the low level of COVID-19 in this cohort. The findings are also consistent with the possibility of a protective effect of OAT medications on development of the disease.
