Abstract

Patients hospitalized for heart failure have a very high in-hospital as well as one-year mortality. Natriuretic peptides play both a diagnostic and a prognostic role in this disease. Changes of natriuretic peptide levels in response to therapy are a well-known prognostic marker. Regarding in-hospital mortality, however, little is known about the prognostic value of extremely high levels of natriuretic peptides measured on admission. To decide whether extremely high levels of B-type natriuretic peptide have a prognostic value with regard to in-hospital mortality. NT-proBNP levels on admission and in-hospital mortality were extracted retrospectively from the data of patients treated with heart failure in the cardiology department of the Hospital of St. John of God in Budapest. We separately analyzed the data of patients hospitalized for heart failure in 2015 with extremely high initial NT-proBNP levels. The cut-off value in this regard was 10 000 ng/l. We also analyzed the comorbidities of these patients. The median NT-proBNP level of those patients who survived beyond the index hospital stay in the last 10 years was 4842 ng/l, whereas the median NT-proBNP level of those 182 patients who died during their hospital stay was 10 688...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
