(1) Highlight that breast cancer risk increases with age (and does not decline in the absence of risk factors) and communicate the correct frequency for having mammograms; (2) expand primary care physicians' roles in promoting mammography screening for women 65+; and (3) provide Medicare coverage information to older women, particularly those not taking advantage of this benefit.
IDH1/2 mutations are early drivers present in diverse human cancer types arising in various tissue sites. IDH1/2 mutation is known to induce a global hypermethylator phenotype. However, the effects on DNA methylation across IDH mutant cancers and functionally different genome regions, remain unknown. We analyzed DNA methylation data from IDH1/2 mutant acute myeloid leukemia, oligodendroglioma, astrocytoma, solid papillary breast carcinoma with reverse polarity, sinonasal undifferentiated carcinoma and cholangiocarcinoma, which clustered by their embryonal origin. Hypermethylated common probes affect predominantly gene bodies while promoters in IDH1/2 mutant cancers remain unmethylated. Enhancers showed global hypermethylation, however commonly hypomethylated enhancers were associated with tissue differentiation and cell fate determination. We demonstrate that some chromosomes, chromosomal arms and chromosomal regions are more affected by IDH1/2 mutations while others remain resistant to IDH1/2 mutation induced methylation changes. Therefore IDH1/2 mutations have different methylation effect on different parts of the genome, which may be regulated by different mechanisms.
The aim of this study was to examine the influence of emotion on visual information processing and decision making in the context of informed consent. Researchers are ethically obligated to ensure informed consent in clinical trials; however, many volunteers have unrealistic expectations about the value of an experimental therapy. Moreover, suboptimal participation rates for clinical trials may be partially attributable to perceptions that ethical obligations to volunteers are not met. This study examines whether discrete negative emotions (fear, anger, and sadness) differentially influence information processing, visual attention, and decisions in the context of clinical trial informed consent. Community participants completed a standard emotion induction (or control) and then read an actual consent form from a clinical trial while eye movements were tracked. Fear and anger produced the most prominently different patterns of systematic processing and visual attention, such that fear induced longer fixations to information presented, whereas anger induced shorter fixations. Moreover, among women only, fear increased decisions to participate, compared with anger and neutral emotion. Examinations of associations between eye-tracking variables and self-reported outcomes indicated that for angry participants only, less systematic processing was associated with greater decisions to participate. Negative emotions of any kind decreased accurate perceptions of trial benefit. These patterns suggest a complex interplay among emotion, processing style, and decision making. Future research is necessary to further probe these effects among potential clinical trial volunteers. Published 2016. This article is a U.S Government work and is in the public domain in the USA.
Currently, there are no Hebrew (L2) reading assessments that have been tested to obtain evidence for reliability and validity on which to base decisions about Hebrew instruction. The authors developed a Hebrew benchmark assessment tool for first grade students modeled after Dynamic Indicators of Basic Early Literacy Skills, a standardized test of accuracy and fluency used to identify at-risk students and to monitor student progress. Results of pilot data collection (N = 53) provide evidence for strong alternate form reliability for this measure, as well as evidence for content, face and criterion-related validity. Future directions for research and development are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
