Diagnostic Usefulness of Serum Hyaluronic Acid in Patients with SARS-CoV-2 Infection.

The aim of our study is to comprehensively assess the diagnostic usefulness of serum hyaluronic acid (HA) determination in COVID-19 patients. The study group included 87 patients with COVID-19 disease and 45 healthy subjects. The HA concentration was measured using the immunochemical method.

Availability to predators and a size structure of the Antarctic krill Euphausia superba in the 48.1 CCAMLR subarea.

The Antarctic krill Euphausia superba is a key species in Antarctic waters, mainly because it is a major component of the diet of dominant predators, including penguins. It is also a marine living resource that is commercially harvested. Since 2000, krill fishing has become more concentrated.

Acute-phase proteins as indicators of disease severity and mortality in COVID-19 patients.

The aim of the study was to conduct of relationship of acute-phase proteins (APPs) with the severity of COVID-19 defined by National Institutes of Health and according to the criteria of MEWS scale, with the presence of a cytokine storm, oxygen therapy and patient survival. We enrolled 96 patients with COVID-19 and 30 healthy people. The samples were taken on the day of admission and after 9 days on average.

The Kinetics of Inflammation-Related Proteins and Cytokines in Children Undergoing CAR-T Cell Therapy-Are They Biomarkers of Therapy-Related Toxicities?

CD19-targeted CAR-T cell therapy has revolutionized the treatment of relapsed/refractory (r/r) pre-B acute lymphoblastic leukemia (ALL). However, it can be associated with acute toxicities related to immune activation, particularly cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS). Cytokines released from activated immune cells play a key role in their pathophysiology.
