DNA methylation is an epigenetic mark with important regulatory roles in cellular identity and can be quantified at base resolution using bisulfite sequencing. Most studies are limited to the average DNA methylation levels of individual CpGs and thus neglect heterogeneity within the profiled cell populations. To assess this within-sample heterogeneity (WSH) several window-based scores that quantify variability in DNA methylation in sequencing reads have been proposed. We performed the first systematic comparison of four published WSH scores based on simulated and publicly available datasets. Moreover, we propose two new scores and provide guidelines for selecting appropriate scores to address cell-type heterogeneity, cellular contamination and allele-specific methylation. Most of the measures were sensitive in detecting DNA methylation heterogeneity in these scenarios, while we detected differences in susceptibility to technical bias. Azacitidine Using recently published DNA methylation profiles of Ewing sarcoma samples, we show that DNA methylation heterogeneity provides information complementary to the DNA methylation level. WSH scores are powerful tools for estimating variance in DNA methylation patterns and have the potential for detecting novel disease-associated genomic loci not captured by established statistics. We provide an R-package implementing the WSH scores for integration into analysis workflows. © The Author(s) 2020.

Studies have shown that ABO incompatibility does not have an effect on outcome of HSCT; however, the serologic consequences of these ABO-incompatible transplants can make it difficult to decide when to begin support with donor ABO/Rh-type blood products. METHODS This study explored the use of RBC distribution width (RDW), mean corpuscular volume, and hemoglobin as regularly tested laboratory parameters that could be used as surrogate markers for RBC engraftment in 65 patients who received ABO/Rh-incompatible HSCT. RESULTS The appearance of engrafted donor RBCs correlated with a peak in RDW (P = .002). In addition, our findings suggest that serologic changes in ABO/Rh appear to correspond with a peak in RDW (P = .002). CONCLUSIONS High values of RDW likely result from a substantial proportion of large, young erythrocytes from recent engraftment with smaller, older pretransplant erythrocytes from the recipient. Our findings suggest that peak RDW may be an indicator of erythrocyte engraftment, following an ABO/Rh-incompatible HSCT. © American Society for Clinical Pathology, 2020. All rights reserved.

The objective is to prevent the occurrence of adverse events arising from clinical care activities to focus resources on reducing the impact of the disease by promoting safer health systems and higher quality standards for patient safety in Europe. The Declaration intends to promote a European patient safety culture, starting with safety practices and exchanging effective practices to reduce adverse events arising from health activities. Tuscany, the fifth largest region of Italy, is strongly committed to make this happen. Its Regional Centre for Clinical Risk Management and Patient Safety and WHO Collaborating Centre (GRC Centre-Centro Gestione Rischio Clinico e Sicurezza del Paziente) aims at developing and promoting practices for safety, awareness raising and the analysis of adverse events for the constant improvement of care delivery. © The Author(s) 2020.

The objective of this project was to establish a grounded theory as a tool for practitioners and researchers to understand the experiences of members of grandfamiles. RESEARCH DESIGN AND METHODS In-depth, unstructured interviews with custodial grandparents and grandchildren from 15 grandfamilies were conducted. Classic grounded theory was the methodology used to ask the question, "What are the challenges within grandfamilies and how do they respond to these challenges?" RESULTS The theory emerging from the data, Compounding Complexity, provides an explanatory framework of three interrelated categories of factors that affect complexity in grandfamilies situational, relationship, and emotional complexity. Conflict and change were found to be consistent across the categories of Compounding Complexity. DISCUSSIONS AND IMPLICATIONS Next steps include adding data from interviews with biological parents to Compounding Complexity and applying the theory. Understanding relationship, situational, and emotional complexity in the context of conflict and change enables practitioners to advance their work with grandfamiies. © The Author(s) 2020.

Recent advances in sequencing technologies and bioinformatics tools have led directly to an ever-expanding field of types and biological functions of circRNAs. In parallel with technological developments, practical applications of circRNAs have arisen including their utilization as biomarkers of human disease. Currently, circRNA-associated bioinformatics tools can support projects including circRNA annotation, circRNA identification and network analysis of competing endogenous RNA (ceRNA). In this review, we collected about 100 circRNA-associated bioinformatics tools and summarized their current attributes and capabilities. We also performed network analysis and text mining on circRNA tool publications in order to reveal trends in their ongoing development. © The Author(s) 2020. Published by Oxford University Press.
