Abstract

The HeartMate left ventricular assist system (LVAS) is being used with increasing frequency as a bridge to heart transplantation and for long-term support of chronic heart failure patients who are not transplant candidates. The surgical techniques and anatomic placement of the HeartMate are factors in minimizing complications that occur during long-term use. Device related bleeding, infection, and other intraabdominal complications are serious adverse events associated with the position of the LVAS. Clinical data from 48 HeartMate supported patients were analyzed retrospectively to determine differences in serious complication rates between intraperitoneal (IP) and extraperitoneal (EP) LVAS placement. The LVAS was placed IP in 37 patients (77%) and EP in 11 patients (23%). The occurrence of postoperative bleeding that required reoperation was 57% in the IP group and 64% in the EP group. Device related bleeding was 8% in the IP group and 29% in the EP. Neither difference in bleeding rate was statistically significant. The overall infection rate during the entire period of LVAS support was similar between groups (IP, 45.7%; EP, 46.2%; p = 0.25); however, device related infection occurred more often in the EP group (46%; IP, 14%; ...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.
