The SIOPE strategic plan: A European cancer plan for children and adolescents

[EN] Within the European Network for Cancer research in Children and Adolescents (ENCCA), SIOPE and the European paediatric haematology-oncology community have established a long-term sustainable Strategic Plan to increase the cure rate and the quality of survivorship for children and young people with cancer over the next ten years. The ultimate goal is to increase the diseaseand late-effect- free survival after 10 years from the diagnosis, and beyond. As a result of several initiatives to involve all stakeholders and ensure that all their points of view would be taken into account in the document, this long-term sustainable Strategic Plan has achieved a broad consensus, and will serve as the "European Cancer Plan for Children and Adolescents".This publication has received funding from the European Union's Seventh Framework Programme for research, technological development and demonstration under the project ENCCA (European Network for Cancer research in Children and Adolescents), grant agreement nr.

Autotaxin-LPA Signaling Contributes to Obesity-Induced Insulin Resistance in Muscle and Impairs Mitochondrial Metabolism

Autotaxin (ATX) is an adipokine that generates the bioactive lipid, lysophosphatidic acid (LPA). ATX-LPA signaling has been implicated in diet-induced obesity and systemic insulin resistance. However, it remains unclear whether the ATX-LPA pathway influences insulin function and energy metabolism in target tissues, particularly skeletal muscle, the major site of insulin-stimulated glucose disposal. The objective of this study was to test whether the ATX-LPA pathway impacts tissue insulin signaling and mitochondrial metabolism in skeletal muscle during obesity. Male mice with heterozygous ATX deficiency (ATX+/−) were protected from obesity, systemic insulin resistance, and cardiomyocyte dysfunction following high-fat high-sucrose (HFHS) feeding. HFHS-fed ATX+/− mice also had improved insulin-stimulated AKT phosphorylation in white adipose tissue, liver, heart, and skeletal muscle. Preserved insulin-stimulated glucose transport in muscle from HFHS-fed ATX+/− mice was associated with improved mitochondrial pyruvate oxidation in the absence of changes in fat oxidation and ectopic lipid accumulation. Similarly, incubation with LPA decreased insulin-stimulated AKT phosphorylation and mitochondrial energy metabolism in C2C12 myotubes at baseline and following palmitate-induced insulin resistance. Taken together, our results suggest that the ATX-LPA pathway contributes to obesity-induced insulin resistance in metabolically relevant tissues. Our data also suggest that LPA directly impairs skeletal muscle insulin signaling and mitochondrial function

The Minimal Domain of Adipose Triglyceride Lipase (ATGL) Ranges until Leucine 254 and Can Be Activated and Inhibited by CGI-58 and G0S2, Respectively

Adipose triglyceride lipase (ATGL) is the rate-limiting enzyme of lipolysis. ATGL specifically hydrolyzes triacylglycerols (TGs), thereby generating diacylglycerols and free fatty acids. ATGL's enzymatic activity is co-activated by the protein comparative gene identification-58 (CGI-58) and inhibited by the protein G0/G1 switch gene 2 (G0S2). The enzyme is predicted to act through a catalytic dyad (Ser47, Asp166) located within the conserved patatin domain (Ile10-Leu178). Yet, neither an experimentally determined 3D structure nor a model of ATGL is currently available, which would help to understand how CGI-58 and G0S2 modulate ATGL's activity. In this study we determined the minimal active domain of ATGL. This minimal fragment of ATGL could still be activated and inhibited by CGI-58 and G0S2, respectively. Furthermore, we show that this minimal domain is sufficient for protein-protein interaction of ATGL with its regulatory proteins. Based on these data, we generated a 3D homology model for the minimal domain. It strengthens our experimental finding that amino acids between Leu178 and Leu254 are essential for the formation of a stable protein domain related to the patatin fold. Our data provide insights into the structure-function relationship of ATGL and indicate higher structural similarities in the N-terminal halves of mammalian patatin-like phospholipase domain containing proteins, (PNPLA1, -2,- 3 and -5) than originally anticipated

The 'Survivorship Passport' for childhood cancer survivors

Background: Currently, there are between 300,000 and 500,000 childhood cancer survivors (CCSs) in Europe. A significant proportion is at high risk, and at least 60% of them develop adverse health-related outcomes that can appear several years after treatment completion. Many survivors are unaware of their personal risk, and there seems to be a general lack of information among healthcare providers about pathophysiology and natural history of treatment-related complications. This can generate incorrect or delayed diagnosis and treatments. Method: The Survivorship Passport (SurPass) consists of electronic documents, which summarise the clinical history of the childhood or adolescent cancer survivor. It was developed by paediatric oncologists of the PanCare and SIOPE networks and IT experts of Cineca, together with parents, patients, and survivors' organisations within the European Union–funded European Network for Cancer research in Children and Adolescents. It consists of a template of a web-based, simply written document, translatable in all European languages, to be given to each CCS. The SurPass provides a summary of each survivor's clinical history, with detailed information about the original cancer and of treatments received, together with personalised follow-up and screening recommendations based on guidelines published by the International Guidelines Harmonization Group and PanCareSurFup. Results: The SurPass data schema contains a maximum of 168 variables and uses internationally approved nomenclature, except for radiotherapy fields, where a new classification was defined by radiotherapy experts. The survivor-specific screening recommendations are mainly based on treatment received and are automatically suggested, thanks to built-in algorithms. These may be adapted and further individualised by the treating physician in case of special disease and survivor circumstances. The SurPass was tested at the Istituto Giannina Gaslini, Italy, and received positive feedback. It is now being integrated at the institutional, regional and national level. Conclusions: The SurPass is potentially an essential tool for improved and more harmonised follow-up of CCS. It also has the potential to be a useful tool for empowering CCSs to be responsible for their own well-being and preventing adverse events whenever possible. With sufficient commitment on the European level, this solution should increase the capacity to respond more effectively to the needs of European CCS

The European Cancer Patient’s Bill of Rights, update and implementation 2016

In this implementation phase of the European Cancer Patient’s Bill of Rights (BoR), we confirm the following three patient-centred principles that underpin this initiative: 1: The right of every European citizen to receive the most accurate information and to be proactively involved in his/her care. 2: The right of every European citizen to optimal and timely access to a diagnosis and to appropriate specialised care, underpinned by research and innovation. 3: The right of every European citizen to receive care in health systems that ensure the best possible cancer prevention, the earliest possible diagnosis of their cancer, improved outcomes, patient rehabilitation, best quality of life and affordable health care. The key aspects of working towards implementing the BoR are: - Agree our high-level goal. The vision of 70% long-term survival for patients with cancer in 2035, promoting cancer prevention and cancer control and the associated progress in ensuring good patient experience and quality of life. - Establish the major mechanisms to underpin its delivery. (1) The systematic and rigorous sharing of best practice between and across European cancer healthcare systems and (2) the active promotion of Research and Innovation focused on improving outcomes; (3) Improving access to new and established cancer care by sharing best practice in the development, approval, procurement and reimbursement of cancer diagnostic tests and treatments. - Work with other organisations to bring into being a Europe based centre that will (1) systematically identify, evaluate and validate and disseminate best practice in cancer management for the different countries and regions and (2) promote Research and Innovation and its translation to maximise its impact to improve outcomes

Association between Helicobacter pylori Colonization and Inflammatory Bowel Disease: A Systematic Review and Meta-Analysis

Background: Various observational studies have examined a potential relationship between Helicobacter pylori colonization and inflammatory bowel diseases (IBDs); however, results are inconclusive. This systematic review evaluates articles reporting an association between human H. pylori colonization and IBD. Methods: A systematic search of studies was conducted to evaluate a possible relationship between H. pylori colonization and IBD. Seven databases and different types of gray literature were searched. After screening for relevant articles, selection and data extraction were done. After that, the data were analyzed, and pooled odds ratios (ORs) were calculated, using meta-analysis. Heterogeneity, sensitivity, and subgroups analyses were conducted. Funnel plots followed by Begg and Egger tests were done to assess the publication bias. Results: Among 58 studies, including 13,549 patients with IBD and 506,554 controls, the prevalence of H. pylori colonization was 22.74 and 36.30, respectively. A significant negative association was observed between H. pylori colonization and IBD (pooled OR: 0.45, 95 confidence interval 0.39-0.53, P�0.001). The random-effect model showed significant statistical heterogeneity in the included studies (I2=79). No publication bias was observed. Among subgroups, ORs were notably different when the data were stratified by the age difference between patient and control group, and by study regions and/or continent. Finally, the meta-regression analysis showed significant results, in terms of the age difference and region variables. Conclusions: In this meta-analysis, all statistical data support the theory that H. pylori has a protective role in IBD. However, more primary studies using proper methodology are needed to confirm this association. Copyright © 2020 Wolters Kluwer Health, Inc. All rights reserved

Microbial induced acid corrosion from a field perspective - Advances in process understanding and construction material development

Microbial induced acid corrosion is accounted for ~40 % of the degradation of subsurface wastewater infrastructure globally. While fundamental process understanding has increased significantly within the last decades, to date no sustainable building material exists, which meets the long-term requirements in such aggressive and corrosive environments. This work describes a novel model based on field studies, conducted in various Austrian sewer networks, intertwining biological, mineralogical and hydro-chemical factors. Additionally, an extensive field testing campaign over the duration of 18 months, conducted on different geopolymer concretes (GPC), particularly designed for the latter environments will be presented. Innovative GPCs were tested regarding their microstructural behavior, microbial accessibility and hydro-chemical alterations over time and compared to commercially produced cement based products, including OPC and CAC concretes. Additionally, the system specific environmental parameters, such as relevant gas concentrations (H2S, CO2, CH4), relative humidity and temperature were constantly monitored
