Community stroke knowledge: a new information strategy using a joint project of the public health service and the hairdressers' guild of the Wesel district
Objectives: The public health programme âHealthy Lower RhineâŠagainst Strokeâ is aimed at improving the populationâs knowledge about stroke and thus at reducing the prehospital phase in patients with suspected stroke. First evaluation results indicate that apart from providing information through the mass media, there is an urgent need to further develop the face-to-face communication approach. This has to be achieved by efficient but also effective means, given that financial and personnel resources are scarce. Study design: In cooperation with lögd Bielefeld, the Lower Health Authority of the Wesel District (health department) developed a postcard-sized quiz card containing exclusively correct answers on the issue of stroke, risk factors as well as symptom and action knowledge. For face-to-face communication, the hairdressers could be convinced to be included in the project. The hairdressers posed the corresponding questions and marked those answers of the clients that were identical with the quiz card answers with a cross. Answers not given by the clients were read out loud to them by the hairdressers, who were thus âstyling upâ the knowledge of their clients. To increase participation in the project, prizes were offered for the hairdressers with the most filled-in quiz cards as well as for three of the participating clients (drawing of prizes 1â3). More than 380 hairdressers in the Wesel district were sent a letter inviting them to participate as facilitators in this project, which is probably the first of its kind worldwide. Methods: The machine-readable quiz cards were collected and statistically evaluated including data regarding age and gender of the participants. Results were to be presented in the form of a descriptive statistic. Results: Thirty-three hairdressers from 12 cities and municipalities of the Wesel district participated in this joint action of the Wesel district Department of Health and the Wesel hairdressersâ guild, dealing with the monitoring and imparting of basic knowledge on the issue of stroke. Almost 2,000 clients were interviewed by the participating hairdressers, and knowledge gaps were closed by information read out to them. Discussion: This innovative approach of imparting knowledge can be regarded as the model of an effective and economical way of communicating health information to the broader public

Non-tariff measures affecting agro-food trade between the EU and Africa Summary of a workshop
This report contains the presentations and the summary of the IPTS workshop "Non Tariff Measures (NTMs) affecting agro-food trade between the EU and Africa" held in September 2010 in Seville. The workshop brought together experts from research, policy making and business in order to exchange knowledge and discuss about NTMs and the issues associated with them. The workshop first gave an overview of NTM classifications as well as the methods in the analysis of NTMs. With this background case studies were presented, focusing on NTMs from the perspective of African exporters of agro-food products.JRC.DDG.J.5-Agriculture and Life Sciences in the Econom
Gender comparison of clinical, histopathological, therapeutic and outcome factors in 185,967 colon cancer patients
Introduction: Colorectal carcinomas represent the third most common cause of cancer-related deaths in Germany. Although the incidence is significantly higher in men compared with women and gender is a well-established crucial factor for outcome in other diseases, detailed gender comparisons for colon cancer are lacking.
Methods: This retrospective population-based cohort study included all patients diagnosed with colon cancer in Germany between 2000 and 2016 who were included in the common dataset of colorectal cancer patients from the quality conference of the German Cancer Society. We compared clinical, histopathological, and therapeutic characteristics as well as overall and recurrence-free survival.
Results: A total of 185,967 patients were included in the study, of which 85,685 were female (46.1%) and 100,282 were male (53.9%). The proportion of women diagnosed with colon cancer decreased from 2000 to 2016 (f: 26.6 to 40.1%; m: 24.9 to 41.9%; p < 0.001), and the proportion of very old patients was especially high in women (f: 27.3%; m: 15.6%; p < 0.001). The localization in women was more right-sided (f: 45.0%, m: 36.7%; p < 0.001), and women had a higher tumor grading and a higher UICC stage (especially stage III nodal-positive) at diagnosis of primary colon cancer (UICC III: f: 22.7%, m: 21.0%; p < 0.001). We could detect a significantly better overall (hazard ratio: 0.853, lower 95%: 0.841, upper 95%: 0.864; p < 0.001) and recurrence-free survival (hazard ratio: 0.857, lower 95%: 0.845, upper 95%: 0.868; p < 0.001) in women compared with men, even though women received chemotherapy less frequently compared with men (f: 26.1%, m: 28.1%; p < 0.001).
Conclusion: We could detect several variables that differed significantly between men and women regarding clinical, histopathological, therapeutic, and outcome factors. We believe that it is crucial to consider gender as a key factor in the diagnosis and treatment of colon cancer. Sex-specific diagnostic tools could lead to an earlier diagnosis of colon cancer in women, and ways to increase the rate of chemotherapy in women should be evaluated. Furthermore, we recommend stratifying randomized trials by gender
Food security impact of global equities : executive summary
This study describes methodologies that have been developed to assess the food security impact of agricultural technologies supplied by stock exchange companies on the basis of publicly available revenue data. The methods have been developed for fertiliser, improved seeds, cooling and packaging. Given the lack of information on key variables at present it is only possible to apply the method for fertiliser to all companies that sell the technology in their portfolio. For the other three technologies additional information is necessary that is not publicly available
Cryo-EM structure of the fully assembled elongator complex
Transfer RNA (tRNA) molecules are essential to decode messenger RNA codons during protein synthesis. All known tRNAs are heavily modified at multiple positions through post-transcriptional addition of chemical groups. Modifications in the tRNA anticodons are directly influencing ribosome decoding and dynamics during translation elongation and are crucial for maintaining proteome integrity. In eukaryotes, wobble uridines are modified by Elongator, a large and highly conserved macromolecular complex. Elongator consists of two subcomplexes, namely Elp123 containing the enzymatically active Elp3 subunit and the associated Elp456 hetero-hexamer. The structure of the fully assembled complex and the function of the Elp456 subcomplex have remained elusive. Here, we show the cryo-electron microscopy structure of yeast Elongator at an overall resolution of 4.3 Ă
. We validate the obtained structure by complementary mutational analyses in vitro and in vivo. In addition, we determined various structures of the murine Elongator complex, including the fully assembled mouse Elongator complex at 5.9 Ă
resolution. Our results confirm the structural conservation of Elongator and its intermediates among eukaryotes. Furthermore, we complement our analyses with the biochemical characterization of the assembled human Elongator. Our results provide the molecular basis for the assembly of Elongator and its tRNA modification activity in eukaryotes
Intestinal B-cells license metabolic T-cell activation in NASH microbiota/antigen-independently and contribute to fibrosis by IgA-FcR signalling
BACKGROUND & AIMS
The progression of nonalcoholic steatohepatitis (NASH) to fibrosis and hepatocellular carcinoma (HCC) is aggravated by auto-aggressive T cells. The gut-liver axis contributes to NASH, but the mechanisms involved and the consequences for NASH-induced fibrosis and liver cancer remain unknown. We investigated the role of gastrointestinal B cells in the development of NASH, fibrosis and NASH-induced HCC.
METHODS
C57BL/6J wild-type (WT), B cell-deficient and different immunoglobulin-deficient or transgenic mice were fed distinct NASH diets (for example, choline-deficient high-fat diet, CD-HFD) or chow diet for 6 or 12 months, whereafter NASH, fibrosis, and NASH-induced HCC were assessed and analysed. Specific pathogen-free/germ-free WT and ÎŒMT mice (containing B cells only in the gastrointestinal tract) were fed a CD-HFD, and treated with an anti-CD20 antibody, whereafter NASH and fibrosis were assessed. Tissue biopsy samples from patients with NAFL, NASH and cirrhosis were analysed to correlate the secretion of immunoglobulins to clinicopathological features. Flow cytometry, immunohistochemistry and scRNA-Seq analysis were performed in liver and gastrointestinal tissue for immune cells in mice and humans.
RESULTS
Activated intestinal B cells were increased in mouse and human NASH samples and licensed metabolic T-cell activation to induce NASH independently of antigen-specificity and gut microbiota. Genetic or therapeutic depletion of systemic or gastrointestinal B cells prevented or reverted NASH and liver fibrosis. IgA secretion was necessary for fibrosis induction by activating CD11b+CCR2+F4/80+CD11c-FCGR1+ hepatic myeloid cells through an IgA-FcR signalling axis. Similarly, patients with NASH had increased numbers of activated intestinal B-cells and showed a positive correlation between IgA levels and activated FcRÎł+ hepatic myeloid cells as well extent of liver fibrosis.
CONCLUSIONS
Intestinal B cells and the IgA-FcR signalling axis represent potential therapeutic targets for treating NASH.
IMPACT AND IMPLICATIONS
Nonalcoholic steatohepatitis (NASH) is a chronic inflammatory condition on the rise and can lead to hepatocellular carcinoma (HCC), the 3rd most common cause of cancer-related death worldwide. Currently, there is no effective treatment for this progressive disease that correlates with a marked risk of HCC mortality and carries a substantial healthcare burden. To date, among all the solid tumours, especially in HCC, the incidence and mortality rates are almost the same, making it crucial to find curative treatments for chronic diseases, such as NASH, which highly predispose to tumorigenesis. We have previously shown that NASH is an auto-aggressive condition aggravated, amongst others, by T cells. Therefore, we hypothesized that B cells might have a role in disease induction and progression. Our present work highlights that B cells have a dual role in NASH pathogenesis, being implicated in the activation of auto-aggressive T cells and the development of fibrosis via activation of monocyte-derived macrophages by secreted immunoglobulins (e.g., IgA). Furthermore, we could show that the absence of B cells prevented HCC development. B-cell intrinsic signalling pathways, secreted immunoglobulins, and interactions of B cells with other immune cells are potential targets in combinatorial NASH therapies against inflammation and fibrosis
