Toxicological Response of Chironomus dilutus in Single Chemical and Binary Mixture Exposure Experiments with Six Perfluoralkyl Substances.

Environ Toxicol Chem 2021 Apr 9. Epub 2021 Apr 9.

Towson University, Towson, Maryland, USA.

Few studies have determined the toxicity of perfluoralkyl substances to aquatic invertebrates.

Lead aVR predicts early revascularization but not long-term events in patients referred for stress electrocardiography.

PLoS One 2021 8;16(4):e0249779. Epub 2021 Apr 8.

Division of Cardiovascular Medicine, Department of Medicine, The Cardiovascular Imaging Center, University of Virginia Health System, Charlottesville, VA, United States of America.

Background: Exercise stress electrocardiography (ExECG) is recommended as a first-line tool to assess ischemia, but standard ST-analysis has limited diagnostic accuracy. ST elevation in lead aVR has been associated with left main and LAD disease in the population undergoing coronary angiography but has not been studied in the general population undergoing stress testing for the initial evaluation of CAD without coronary angiography. We sought to determine the predictive value of lead aVR elevation for ischemia, early revascularization, and subsequent cardiac events in consecutive patients undergoing ExECG. Read More

Association of oral contraceptives and tubal ligation with risk of early natural menopause.

Hum Reprod 2021 Apr 2. Epub 2021 Apr 2.

Department of Biostatistics and Epidemiology, School of Public Health and Health Sciences, University of Massachusetts, Amherst, MA 01003, USA.

Study Question: What is the association of oral contraceptives (OCs) and tubal ligation (TL) with early natural menopause?

Summary Answer: We did not observe an association of OC use with risk of early natural menopause; however, TL was associated with a modestly higher risk.

What Is Known Already: OCs manipulate hormone levels, prevent ovulation, and may modify the rate of follicular atresia, while TL may disrupt the blood supply to the ovaries. These mechanisms may be associated with risk of early menopause, a condition associated with increased risk of cardiovascular disease and other adverse health outcomes. Read More
