The study was aimed at the characterization of humoral immunity in acute SARS-CoV-2 infection. ⋯ Severe course of COVID-19 is associated with significant changes of phenotypes of circulating B-lymphocytes and elevated circulating plasmablasts correlate with decreased SARS-CoV-2-specific IgG antibodies (Tab. 2, Fig. 3, Ref. 14).

This study is aimed to determine the relationship between 25-OH vitamin D levels, inflammatory parameters of neutrophil‑to‑lymphocyte ratio (NLR), platelet‑to‑lymphocyte ratio (PLR), c‑reactive protein (CRP) levels and the disease severity of COVID-19 infection. ⋯ There is no relationship between the severity of COVID-19 infection and 25-OH vitamin D deficiency. Inflammatory parameters are associated with the disease severity, while NLR is an independent predictor of severe COVID-19. There was no correlation between 25-OH vitamin D and inflammatory markers (Tab. 4, Fig. 1, Ref. 38).

Cardiac valvular calcification (CVC) is the main cause of cardiovascular disease and all-cause death in patients with chronic kidney disease (CKD). However, the relationship between Neutrophil lymphocyte ratio (NLR) and CVC in patients with CKD is not clear. In this study, we aimed to investigate the prevalence of CVC in newly diagnosed patients with non-dialysis CKD stage 3-5 and evaluate the correlation between NLR and CVC. ⋯ CVC is not uncommon in newly diagnosed patients with non-dialysis CKD stage 3-5, and NLR is an independent risk factor for CVC (Tab. 4, Fig. 1, Ref. 34).

To determine the current situation and trends in bronchology in the Czech Republic (CR), a questionnaire survey has been conducted by the Czech Pneumological and Phthisiological Society (CPFS). ⋯ Based on the BRS survey in 2020 it can be concluded that Czech bronchology is developing in the right direction and is well equipped with both, staff and technical devices. We are adopting new methods without delays and we expand the use of those working well (EBUS) (Tab. 4, Ref. 13).

Multicenter Study Observational Study
Impact of prehospital IV furosemide or nitrate application on hospital outcome in acute heart failure patients.
This study aims to evaluate the association between prehospital intravenous therapy and clinical outcomes in the patients with acute heart failure. ⋯ Prehospital treatment with IV furosemide or nitrates in AHF patients seemed to have no major impact on hospital mortality or length of hospitalization after adjustment for several cofounders (Tab. 2, Ref. 16).
