by Tracey Peake, North Carolina State University Fabrication and characterization of SHIELD. a, Schematic showing the concept of the SHIELD method. Dry SHIELD particles (gray spheres) are inhaled and they become swollen (blue spheres) once they are in contact with the mucus layer (pink layer). Finally, it forms a layer of hydrogel (blue layer) and adheres...
By Thor Christensen, American Heart Association News (Irina Shatilova/iStock via Getty Images) People hospitalized with COVID-19 may have an increased risk for heart damage, but not so much the type of inflammation previous research suggested, according to a new study. Early in the pandemic, several studies suggested many COVID-19 survivors experienced heart damage even if...

AMERICAN ACADEMY OF FAMILY PHYSICIANS Although primary care clinics were disrupted by the COVID-19 pandemic, a study by Minnesota researchers showed that care management processes for chronic disease care in the primary care setting generally increased from 2019 to 2021. The team used data from 269 primary care clinics in 2017, 2019 and 2021, as...
MEDICAL UNIVERSITY OF VIENNA Using prenatal magnetic resonance imaging, a group of MedUni Vienna researchers examined the placentas and foetuses of women who tested positive for SARS-CoV-2 during pregnancy. Their research results demonstrate that the different strains of the virus that emerged during the pandemic led to varying degrees of damage: especially involving pre-Omicron variants,...

That is one of the key findings from our recent multicountry study on long COVID-19—or long COVID—recently published in...
by Jim Wappes, University of Minnesota RNA in situ (RNAscope) detection of SARS-CoV-2 in extrapulmonary tissues. a–h, SARS-CoV-2 virus is localized to the Golgi and endoplasmic reticulum, perinuclear in appearance, in the following organs and cell types (×500 magnifications, scale bars, 2 μm, all panels): thyroid of P19, demonstrating the presence of virus in follicular cells...
by Karolinska Institutet Schematic illustration of mechanisms underlying SARS-CoV-2-induced adipose atrophy and weight loss. SARS-CoV-2 infection triggers dyspnea and pathological changes in the infected lung tissues, including pulmonary edema, inflammation, and obstruction of pulmonary alveoli. These pathological alterations induce local hypoxia in the lung tissue and systemic hypoxia in other tissues. Hypoxia serves as a...
By Neha Mathur Nov 24 2022 Reviewed by Danielle Ellis, B.Sc. In a recent study published in PLOS Medicine, researchers determined the vaccine effectiveness (VE) of the primary coronavirus disease 2019 (COVID-19) vaccination series. They determined VE against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reinfection, COVID-19-related hospitalization, and mortality. In this way, the researchers assessed...
