    arachidonic acid - biomarkers - cardiovascular diseases - diet - epidemiology - linoleic acid - primary prevention

    Background: Global dietary recommendations for and cardiovascular effects of linoleic acid, the major dietary omega-6 fatty acid, and its major metabolite, arachidonic acid, remain controversial. To address this uncertainty and inform international recommendations, we evaluated how in vivo circulating and tissue levels of linoleic acid (LA) and arachidonic acid (AA) relate to incident cardiovascular disease (CVD) across multiple international studies. Methods: We performed harmonized, de novo, individual-level analyses in a global consortium of 30 prospective observational studies from 13 countries. Multivariable-adjusted associations of circulating and adipose tissue LA and AA biomarkers with incident total CVD and subtypes (coronary heart disease, ischemic stroke, cardiovascular mortality) were investigated according to a prespecified analytic plan. Levels of LA and AA, measured as the percentage of total fatty acids, were evaluated linearly according to their interquintile range (ie, the range between the midpoint of the first and fifth quintiles), and categorically by quintiles. Study-specific results were pooled using inverse-variance-weighted meta-analysis. Heterogeneity was explored by age, sex, race, diabetes mellitus, statin use, aspirin use, omega-3 levels, and fatty acid desaturase 1 genotype (when available). Results: In 30 prospective studies with medians of follow-up ranging 2.5 to 31.9 years, 15 198 incident cardiovascular events occurred among 68 659 participants. Higher levels of LA were significantly associated with lower risks of total CVD, cardiovascular mortality, and ischemic stroke, with hazard ratios per interquintile range of 0.93 (95% CI, 0.88-0.99), 0.78 (0.70-0.85), and 0.88 (0.79-0.98), respectively, and nonsignificantly with lower coronary heart disease risk (0.94; 0.88-1.00). Relationships were similar for LA evaluated across quintiles. AA levels were not associated with higher risk of cardiovascular outcomes; in a comparison of extreme quintiles, higher levels were associated with lower risk of total CVD (0.92; 0.86-0.99). No consistent heterogeneity by population subgroups was identified in the observed relationships. Conclusions: In pooled global analyses, higher in vivo circulating and tissue levels of LA and possibly AA were associated with lower risk of major cardiovascular events. These results support a favorable role for LA in CVD prevention.

    Background: The metabolic effects of omega-6 polyunsaturated fatty acids (PUFAs) remain contentious, and little evidence is available regarding their potential role in primary prevention of type 2 diabetes. We aimed to assess the associations of linoleic acid and arachidonic acid biomarkers with incident type 2 diabetes. Methods: We did a pooled analysis of new, harmonised, individual-level analyses for the biomarkers linoleic acid and its metabolite arachidonic acid and incident type 2 diabetes. We analysed data from 20 prospective cohort studies from ten countries (Iceland, the Netherlands, the USA, Taiwan, the UK, Germany, Finland, Australia, Sweden, and France), with biomarkers sampled between 1970 and 2010. Participants included in the analyses were aged 18 years or older and had data available for linoleic acid and arachidonic acid biomarkers at baseline. We excluded participants with type 2 diabetes at baseline. The main outcome was the association between omega-6 PUFA biomarkers and incident type 2 diabetes. We assessed the relative risk of type 2 diabetes prospectively for each cohort and lipid compartment separately using a prespecified analytic plan for exposures, covariates, effect modifiers, and analysis, and the findings were then pooled using inverse-variance weighted meta-analysis. Findings: Participants were 39 740 adults, aged (range of cohort means) 49-76 years with a BMI (range of cohort means) of 23·3-28·4 kg/m2, who did not have type 2 diabetes at baseline. During a follow-up of 366 073 person-years, we identified 4347 cases of incident type 2 diabetes. In multivariable-adjusted pooled analyses, higher proportions of linoleic acid biomarkers as percentages of total fatty acid were associated with a lower risk of type 2 diabetes overall (risk ratio [RR] per interquintile range 0·65, 95% CI 0·60-0·72, p<0·0001; I 2=53·9%, pheterogeneity=0·002). The associations between linoleic acid biomarkers and type 2 diabetes were generally similar in different lipid compartments, including phospholipids, plasma, cholesterol esters, and adipose tissue. Levels of arachidonic acid biomarker were not significantly associated with type 2 diabetes risk overall (RR per interquintile range 0·96, 95% CI 0·88-1·05; p=0·38; I 2=63·0%, pheterogeneity<0·0001). The associations between linoleic acid and arachidonic acid biomarkers and the risk of type 2 diabetes were not significantly modified by any prespecified potential sources of heterogeneity (ie, age, BMI, sex, race, aspirin use, omega-3 PUFA levels, or variants of the FADS gene; all pheterogeneity≥0·13). Interpretation: Findings suggest that linoleic acid has long-term benefits for the prevention of type 2 diabetes and that arachidonic acid is not harmful. Funding: Funders are shown in the

    De Nederlandse visserij in de toekomst: "Kennis delen en innoveren"
    Bolman, B.C. - \ 2016
    Wageningen Marine Research
    Tijdens een forumdiscussie vanuit de jaarlijkse Visserij in Cijfers, georganiseerd door het LEI, kwamen verschillende thema’s aan de orde, waaronder kennis delen en innoveren. Om te innoveren is het transparant zijn en delen van kennis van groot belang. Juist ook om andere partijen er bij te betrekken, partijen die je hard nodig hebt om tot innovaties te komen. Ervaringen uit de visserij tonen dit aan. Frans Veenstra vertelt zijn ervaringen vanuit het Masterplan Visserij, aangevuld door Christien Absil (toen nog van Stichting de Noordzee) en Bas Bolman.
    The Yankees of Europe? A New View on Technology and Productivity in German Manufacturing in the Early Twentieth Century
    Timmer, Marcel P. ; Veenstra, Joost ; Woltjer, P.J. - \ 2016
    Journal of Economic History 76 (2016)3. - ISSN 0022-0507 - p. 874 - 908.
    Labor productivity in German manufacturing lagged behind the United States in the early twentieth century. Traditionally, this is attributed to dichotomous technology paths across the Atlantic. However, various industry case studies suggest rapid diffusion of U.S. technologies in Germany. We develop a novel framework to reconcile these findings. Labor-productivity gaps are decomposed into differences in technology and differences in the efficiency with which technology is used. We find that by 1936 in the majority of industries inefficient assimilation of modern technologies - and not the use of different technology - accounted for most of the U.S./German labor-productivity gap.
    Integrating ICT applications for farm business collaboration processes using FIspace

    Agri-Food Supply Chain Networks are required to increase production and to be transparent while reducing environmental impact. This challenges farm enterprises to innovate their production processes. These processes need to be supported by advanced ICT components that are developed by multiple vendors and owned by different enterprises. These ICT components should use future internet technologies to enable integration. To make these future internet technologies easily available, the European Commission started a Future Internet Public-Private Partnership Programme (FI-PPP). As part of this FI-PPP the FIspace project started with the development of a cloud-based platform to support business to business collaboration, enabling the formation of domain specific Software Ecosystems. These FIspace Software Ecosystems should drive the development of integrated and extensible collaboration services together with an initial set of domain applications that can support business processes and enables collaboration in networks. The FIspace Platform will enable integration of legacy systems, extending their functionality. This paper presents two use case scenarios for the smart application of pesticides to protect crops and keep them safe for diseases. These scenarios provide architectural descriptions how FIspace Platform configurations can support these processes. Based on these specific use case scenarios, generic use case scenarios and architectural descriptions are derived. These results can be used to develop FIspace Platform configurations supporting collaboration processes in other domains.

    onderwaterakoestiek - uitrusting - schepen - aquatische ecosystemen - monitoring - visserijbeheer - underwater acoustics - equipment - ships - aquatic ecosystems - monitoring - fishery management
    Het gebruik van onderwater acoustics wordt steeds belangrijker in de komende jaren. Steeds vaker wordt het hele ecosysteem in overweging genomen in het proces van het vaststellen van duurzame exploitatieniveaus voor vissoorten. Zo´n ´ecosysteem-benadering´ in het visserijbeheer zal sterk afhankelijk zijn van surveys die het hele ecosysteem onderzoeken, van plankton onder aan de voedselketen tot vis en andere marine predatoren aan de top daarvan. Akoestische methoden kunnen hierin voorzien, want daarmee kunnen in korte tijd grote zeegebieden intensief worden onderzocht. Gebruik van verschillende frequenties helpt om organismen in het echogram te identificeren en moderne kwantitatieve multi-beam echosounders kunnen een groot watervolume scannen. Momenteel loopt Nederland achter bij andere landen voor wat betreft het gebruik van hydro-akoetische apparatuur en technieken. De onderzoeksschepen van Noorwegen, Ierland, Frankrijk en Schotland zijn al uitgerust met 4-6 verschillende akoestische frequenties, waardoor gemakkelijk en betrouwbaard vis kan worden geïdentificeerd. Daarnaast zijn multi-beam echosounders, die per seconde tot 500 akoestische signalen uitzenden in gebruik op o.a. de Noorse ´G.O. Sars´. Dergelijke apparatuur is onmisbaar als het hele ecosysteem moet worden onderzocht. In 2012 zal een mogelijke refit plaatsvinden van de Tridens. Ter onderbouwing van 'nut en noodzaak' om bij deze refit ook dit schip met een dropkeel uit te rusten (een dropkeel is een stalen druppelvormige constructie die tot enkele meters onder het schip kan worden uitgeschoven en die plaats biedt aan meerdere transducers en een multibeam echosounder tegelijkertijd), heeft IMARES naar aanleiding van een helpdeskvraag van de afdeling AKV van het Ministerie van EL&I van 17-20 mei 2011 een technische factfinding missie naar Noorwegen georganiseerd. In dit rapport wordt hiervan verslag gedaan.
