Statins and Left Ventricular Ejection Fraction Following Doxorubicin Treatment.

Background: Statins taken for cardiovascular indications by patients with breast cancer and lymphoma during doxorubicin treatment may attenuate left ventricular ejection fraction (LVEF) decline, but the effect of statins on LVEF among patients with no cardiovascular indications is unknown.

Methods: A double-blind, placebo-controlled, 24-month randomized trial of 40 mg of atorvastatin per day administered to patients with breast cancer and lymphoma receiving doxorubicin was conducted within the National Cancer Institute Community Oncology Research Program across 31 sites in the United States. At pretreatment and then 6 and 24 months after initiating doxorubicin, we assessed left ventricular (LV) volumes, strain, mass, and LVEF through cardiac magnetic resonance imaging, along with cognitive function and serum markers of inflammation.

Pediatric Cancer By Race, Ethnicity and Region in the United States.

Background: In a 2018 descriptive study, cancer incidence in children (age 0-19) in diagnosis years 2003 to 2014 was reported as being highest in New Hampshire and in the Northeast region.

Methods: Using the Cancer in North America (CiNA) analytic file, we tested the hypotheses that incidence rates in the Northeast were higher than those in other regions of the United States either overall or by race/ethnicity group, and that rates in New Hampshire were higher than the Northeast region as a whole.

Results: In 2003 to 2014, pediatric cancer incidence was significantly higher in the Northeast than other regions of the United States overall and among non-Hispanic Whites and Blacks, but not among Hispanics and other racial minorities.

Kidney Cancer Risk Associated with Historic Groundwater Trichloroethylene Contamination.

Trichloroethylene (TCE) is a well-documented kidney carcinogen based on a substantial body of evidence including mechanistic and animal studies, as well as reports from occupational settings. However, the cancer risks for those in residential exposures such as TCE contamination in groundwater are much less clear. The objective of this study was to perform a detailed spatio-temporal analysis of estimated residential TCE exposure in New Hampshire, US.

Simplified assay for VWF cleaving protease (ADAMTS13) activity and inhibitor in plasma.

The absence of VWF cleaving protease activity (VWFcp, ADAMTS13) has recently been identified as a central component in the pathogenesis of TTP. Several assays for the measurement of ADAMTS13 activity have been described, but most are cumbersome and employ techniques not easily adapted to routine laboratories. Thus, ADAMTS13 assays are available at only a few reference or research laboratories.
