Gender Disparity in Cardiovascular Mortality following Radiation Therapy for Hodgkin's Lymphoma: A Systematic Review

Yaser S KhalidAdam Levine


Background Radiation-induced coronary artery disease (R-CAD) has become an increasingly recognized phenomenon. Although the clinical relationship between radiation therapy and CAD risk is well known, there has been very little investigation of the gender relationship to radiation-induced CAD events and resulting cardiovascular (CV) mortality. We study the gender variation in the incidence of CV events/mortality related to R-CAD in Hodgkin’s Lymphoma (HL) patients. Methods The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used in this systematic review and network meta-analysis. PubMed, google scholar, and Cochrane databases were searched to identify prospective and retrospective observational studies comparing women and men following radiation treatment for Hodgkin's lymphoma. 10 studies were included (4 prospective, 6 retrospective). The primary outcome was incidence of cardiovascular events and mortality. The secondary outcome was all-cause mortality. Meta-regression for age was also performed. Results Of 13,975 patients including 41% females and 59% males, CV events/mortality was noted to be significantly higher in women compared to men (OR 3.74, 95% CI 2.44-5.72, p <0.001). All-cause ...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.

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.

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.
