An anastomotic biliary stricture is a complication of living donor liver transplantation (LDLT) performed using duct-to-duct anastomosis. Despite advances in treating this complication, there is no one established treatment protocol. To investigate the safety, effectiveness, and mid-term outcome of magnetic compression anastomosis (MCA) for treating biliary obstruction after LDLT when the obstruction cannot be resolved by using percutaneous or peroral methods. Retrospective, observational study with standardized treatment and follow-up. Tertiary-care academic medical center. Twelve patients underwent MCA procedures to treat anastomosis site stricture after LDLT. MCA. Bile duct patency, technique performance, and complications were evaluated. We achieved magnet approximation at the anastomotic stricture in 10 of 12 patients (83.3%). The magnets failed to approximate in 2 patients. We achieved recanalization of the stricture site in 10 of 10 patients. We removed an internal catheter in 9 patients. The mean interval from magnet approximation to removal was 74.2 days (range 14-181 days). The mean time from recanalization to removal of the internal catheter was 183 days (range 51-266 days). Patients were examined regularly after rem...Continue Reading

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.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

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.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
