Abstract

Antithrombotic (AT) therapy has been known to increase post-endoscopic resection (ER) bleeding risk; however, there are few studies quantifying the effect of AT agents. This study aimed to analyze the incidence of delayed bleeding (DB) based on AT agents administered and to identify the proper timing of drug cessation. Between January 2011 and March 2017, 7752 patients with 8242 lesions underwent ER for single gastric neoplasm. After a 2:1 propensity score matching using age, sex, specimen size, tumor location, diagnosis, chronic kidney disease, and liver cirrhosis, 798 and 399 lesions were classified as belonging to the matched control (MC) group and AT group, respectively. The clinical outcomes were compared between the 2 groups. The DB rate of the MC and AT groups was 6.3% and 10.0%, respectively. There was no significant difference in the early DB rate between the 2 groups; however, the late DB rate of the AT group was higher than the MC group. The continuation group of the AT group had a higher incidence of DB than their matched control subjects (15.9% vs 5.1%; odds ratio, 3.55; 95% confidence interval, 1.24-10.14; P = .018). In patients taking anticoagulants, heparin bridging therapy (HBT) increased the incidence of DB co...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.
