Abstract

To evaluate the safety and efficacy of bronchial artery embolization (BAE) in patients with primary lung cancer-related hemoptysis and to identify factors associated with hemoptysis-free survival. Data from 84 patients with primary lung cancer (non-small cell [n = 74] and small cell [n = 10]) who underwent BAE from 1997 to 2018 for the management of hemoptysis were retrospectively reviewed. Of these, 53 patients had stage IV lung cancer. The hemoptysis volume prior to initial BAE was trivial (blood-tinged sputum) in 21 patients, moderate (< 300 mL per 24 hours) in 34 patients, and massive (> 300 mL per 24 hours) in 29 patients. Technical success, defined as the ability to selectively embolize the abnormal vessel, was achieved in 83 patients (98.8%), and clinical success was achieved in 69 (82.1%) patients. Polyvinyl alcohol particles were used to embolize in 51 patients, gelfoam in 15 patients, and gelfoam plus microcoils in 17 patients. Hemoptysis recurred in 20 patients (23.8%) during follow-up. The median hemoptysis-free survival and overall survival periods were both 61 days. In the clinical-success and clinical-failure groups, the median overall survival period was 99 and 9 days, respectively (P < .001). In multivariable a...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.
