Joint data analysis in nutritional epidemiology: Identification of observational studies and minimal requirements
Background: Joint data analysis from multiple nutrition studies may improve the ability to answer complex questions regarding the role of nutritional status and diet in health and disease.Objective: The objective was to identify nutritional observational studies from partners participating in the European Nutritional Phenotype Assessment and Data Sharing Initiative (ENPADASI) Consortium, as well asminimal requirements for joint data analysis.Methods: A predefined template containing information on study design, exposure measurements (dietary intake, alcohol and tobacco consumption, physical activity, sedentary behavior, anthropometric measures, and sociodemographic and health status), main health-related outcomes, and laboratory measurements (traditional and omics biomarkers) was developed and circulated to those European research groups participating in the ENPADASI under the strategic research area of "diet-related chronic diseases." Information about raw data disposition and metadata sharing was requested. A set of minimal requirements was abstracted from the gathered information.Results: Studies (12 cohort, 12 cross-sectional, and 2 case-control) were identified. Two studies recruited children only and the rest recruited adults. All studies included dietary intake data. Twenty studies collected blood samples. Data on traditional biomarkers were available for 20 studies, of which 17 measured lipoproteins, glucose, and insulin and 13 measured inflammatory biomarkers. Metabolomics, proteomics, and genomics or transcriptomics data were available in 5, 3, and 12 studies, respectively. Although the study authors were willing to share metadata, most refused, were hesitant, or had legal or ethical issues related to sharing raw data. Forty-one descriptors of minimal requirements for the study data were identified to facilitate data integration.Conclusions: Combining study data sets will enable sufficiently powered, refined investigations to increase the knowledge and understanding of the relation between food, nutrition, and human health. Furthermore, t he minimal requirements for study data may encourage more efficient secondary usage of existing data and provide sufficient information for researchers to draft future multicenter research proposals in nutrition
A Six-Gene Signature Predicts Survival of Patients with Localized Pancreatic Ductal Adenocarcinoma
Jen Jen Yeh and colleagues developed and validated a six-gene signature in patients with pancreatic ductal adenocarcinoma that may be used to better stage the disease in these patients and assist in treatment decisions

dictyExpress: a web-based platform for sequence data management and analytics in Dictyostelium and beyond
Abstract Background Dictyostelium discoideum, a soil-dwelling social amoeba, is a model for the study of numerous biological processes. Research in the field has benefited mightily from the adoption of next-generation sequencing for genomics and transcriptomics. Dictyostelium biologists now face the widespread challenges of analyzing and exploring high dimensional data sets to generate hypotheses and discovering novel insights. Results We present dictyExpress (2.0), a web application designed for exploratory analysis of gene expression data, as well as data from related experiments such as Chromatin Immunoprecipitation sequencing (ChIP-Seq). The application features visualization modules that include time course expression profiles, clustering, gene ontology enrichment analysis, differential expression analysis and comparison of experiments. All visualizations are interactive and interconnected, such that the selection of genes in one module propagates instantly to visualizations in other modules. dictyExpress currently stores the data from over 800 Dictyostelium experiments and is embedded within a general-purpose software framework for management of next-generation sequencing data. dictyExpress allows users to explore their data in a broader context by reciprocal linking with dictyBase—a repository of Dictyostelium genomic data. In addition, we introduce a companion application called GenBoard, an intuitive graphic user interface for data management and bioinformatics analysis. Conclusions dictyExpress and GenBoard enable broad adoption of next generation sequencing based inquiries by the Dictyostelium research community. Labs without the means to undertake deep sequencing projects can mine the data available to the public. The entire information flow, from raw sequence data to hypothesis testing, can be accomplished in an efficient workspace. The software framework is generalizable and represents a useful approach for any research community. To encourage more wide usage, the backend is open-source, available for extension and further development by bioinformaticians and data scientists
Practical Autonomous Cyberhealth for resilient Micro, Small and Medium-sized Enterprises
The EU-funded PALANTIR project proposes a cybersecurity framework combining privacy assurance, data protection, incident detection and recovery aspects under the same platform. The project main focus is on cyber-resilience of SMEs and compliance with the relevant data privacy and protection regulations. The outcomes of the project will be validated in diverse application areas (eHealth, eCommerce, 5G-MEC) and will provide enterprises with security tools that will boost their resilience at a reasonable cost to protect their assets in the ever evolving cyber threat range
Country-specific correlations across Europe between modelled atmospheric cadmium and lead deposition and concentrations in mosses
Previous analyses at the European scale have shown that cadmium and lead concentrations in mosses are
primarily determined by the total deposition of these metals. Further analyses in the current study show
that Spearman rank correlations between the concentration in mosses and the deposition modelled by
the European Monitoring and Evaluation Programme (EMEP) are country and metal-specific. Significant
positive correlations were found for about two thirds or more of the participating countries in 1990,
1995, 2000 and 2005 (except for Cd in 1990). Correlations were often not significant and sometimes
negative in countries where mosses were only sampled in a relatively small number of EMEP grids.
Correlations frequently improved when only data for EMEP grids with at least three moss sampling sites
per grid were included. It was concluded that spatial patterns and temporal trends agree reasonably well
between lead and cadmium concentrations in mosses and modelled atmospheric deposition
