Abstract

Microalbuminuria has been described as a risk factor for progressive cardiovascular and renal diseases. Little is known about its prognostic value in patients (pts) with established heart failure (HF). To assess the role of microalbuminuria as a prognostic marker in patients with chronic HF receiving standard medication. From January 2008 through September 2009, 92 pts with chronic HF, were prospectively included. Mean age was 63.7 ± 12.2 and 37 (40.7%) were male. Mean left ventricular ejection fraction (LVEF) was 52.5 ± 17.5%. Pts under dialysis were excluded. Urinary albumin concentration (UAC) was determined in first morning spot sample of urine. Time to first event (HF hospitalization, emergency department visit for HF or cardiovascular death) was defined as endpoint. Mean follow-up was 11 ± 6.1 months. At the time of inclusion in the study, 38 (41.3%) pts had microalbuminuria and no patient had overt albuminuria. Pts with microalbuminuria had lower left ventricular ejection fraction than the rest of the individuals (47.9 ± 18.5 vs 54.5 ± 17.7%, p=0.08). UAC was higher in patients with events (median 59.8 vs 18 mg/L, p=0.0005). Event-free survival was lower in pts with microalbuminuria as compared with normoalbuminuria (p<0...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.
