Abstract

A 3-year-old boy with hereditary spherocytosis (HS) underwent anatomical correction for double-outlet right ventricle. In addition to acute injury to the red blood cells during cardiopulmonary bypass, chronic mechanical trauma related to the presence of internal conduit and transannular patch must be considered in this patient with HS. We therefore performed splencetomy prior to cardiac surgery to prevent perioperative serious hemolysis. Preoperative examination showed the anatomy was considered suitable for REV procedure. The position of the aorta was anterior, VSD was classified as subpulmonic and associated with subvalvular stenosis. Under cardiopulmonary bypass, infundibular septum was resected and intraventricular tunnel was constructed. The pulmonary artery was transected at the level of the valve commissures and translocated onto the right ventricle without transection of aorta. Right ventricular outflow tract was reconstructed with a patch bearing monocusp. No serious complication due to hemolysis occurred perioperatively. Postoperative angiocardiography revealed no stenosis in both left and right ventricular outflow tract. The patient was discharged on the 57th postoperative day and is doing well.

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.
