    Abstract Only the most perfect mussels end up on our dinner plates. Wageningen researchers aim to process the ones that are too large or broken, while maintaining their health enhancing components such as vitamins, small proteins and omega-3 fatty acids. These can be used in high quality foods and feeds.Together with mussel farmers and producers of supplements, food and aquafeeds we want to explore the full potential of mussels, other bivalves and low trophic life.

    Abstract Introduction: Aortoenteric fistulas (AEF) are infrequent malignant complications of abdominal aortic aneurysms (AAA). We present a unique case of a patient with recurring AAA fistulisations.
    Presentation of case: During oncologic treatment, a 63-year-old male was incidentally diagnosed with infrarenal AAA and assigned follow-up but was hospitalised with anaemia and elevated inflammation markers 14 months later. A CT-angiography scan detected an AAA enlargement, but no extravasation (negative FOBT). Another CTA-scan displayed a pseudoaneurysm and ruptured AAA 10 days later. During a total laparotomy, an enlarged pulsating inflammatory conglomerate without active leakage was detected, with a 2 cm duodenal defect (PAEF). The AAA was resected and replaced by a linear silver-coated Dacron graft. 3,5 years after PAEF, the patient was hospitalised with abdominal pain and haematemesis. He underwent gastroscopies, coloscopies, CT- and CTA-scans - all without significant findings. Only after the capsule-endoscopy detected a jejunal ulcer, the PET-scan visualized active regions in the jejunum and the aortic graft. A total laparotomy was performed; previous stapler-lined jejuno-jejunal anastomosis had adhered to the silver-coated Dacron graft (SAEF). The Dacron graft was removed and replaced with a linear xenograft from bovine pericardium.
    Discussion: No evidence-based recommendations prefer endovascular aneurysm repair (EVAR) over open repair, leaving the strategy dependent on local preferences. Whether EVAR or initial xenograft usage would have shown surpassing results, is speculative, as no graft material/type has proved long-term pre-eminence.
    Conclusions: This case displays AEF's complex treatment and challenging diagnosis. Multimodal diagnostic and strategic approaches should be considered for best patient outcome.

  4. Article: Metabolomics of Arterial Stiffness.

    Abstract Arterial stiffness (AS) is one of the earliest detectable signs of structural and functional alterations of the vessel wall and an independent predictor of cardiovascular events and death. The emerging field of metabolomics can be utilized to detect a wide spectrum of intermediates and products of metabolism in body fluids that can be involved in the pathogenesis of AS. Research over the past decade has reinforced this idea by linking AS to circulating acylcarnitines, glycerophospholipids, sphingolipids, and amino acids, among other metabolite species. Some of these metabolites influence AS through traditional cardiovascular risk factors (e.g., high blood pressure, high blood cholesterol, diabetes, smoking), while others seem to act independently through both known and unknown pathophysiological mechanisms. We propose the term 'arteriometabolomics' to indicate the research that applies metabolomics methods to study AS. The 'arteriometabolomics' approach has the potential to allow more personalized cardiovascular risk stratification, disease monitoring, and treatment selection. One of its major goals is to uncover the causal metabolic pathways of AS. Such pathways could represent valuable treatment targets in vascular ageing.

  5. Article ; Online: Proteolytic enzyme-treated seaweed co-product (Ulva laetevirens) inclusion in corn-soybean and European broiler diets to improve digestibility, health, and performance.

    Abstract The impact of addition of an Ulva laetevirens (previously Ulva rigida) co-product treated with a broad-spectrum endo-protease when added to a standard corn-soy (S) based diet and a diet based on European protein sources (EU) on performance, in vivo digestibility and multiple gastrointestinal characteristics was investigated in broilers. In total, 624 Ross 308 one-day-old male broilers were fed one of 6 experimental diets (8 replicates) consisting of a basal diet (S or EU), or a basal diet including the U. laetevirens co-product (U) treated without (U-) or with (U+) a proteolytic enzyme. Starter diets contained 0 (wk 1) and 2.5 (wk 2), and the grower diets (wk 3 and 4) 5% seaweed co-product. In the last 2 wk, birds fed the S vs. EU grower diets showed a higher BW, BWG, and FI, as well as a lower FCR (-0.05 g/g) in wk 3 (P < 0.05). Heavier gizzards (+13%; P < 0.001) and heavier gizzard contents (+92%; P < 0.001) were observed in birds fed the EU vs. S diets, as well as longer villi (+8%; P = 0.010). U diets had a higher water holding capacity than the basal diets (+19%). In wk 4, U inclusion resulted in increased FCR (+0.06 g/g; P < 0.001), water intake (+7%; P < 0.001), and duodenal cross section (+5%; P = 0.033). Enzyme treatment did not affect digestibility of any nutrients, except for ash which was increased in birds fed U+ vs. U- diets (+60%; P < 0.001). U in S diets led to higher, and U in EU diets led to lower apparent pre-cecal digestibility of all nutrients (P < 0.001 for all nutrients). Although for both diet types performance was decreased, dietary U. laetevirens inclusion had different effects when added to a standard corn-soy diet and a diet based on European protein sources. No obvious health effects were observed, leading to the conclusion of the absence of performance of health promoting bioactive components in the U. laetevirens co-product, or of diminishing of these effects due to the proteolytic enzyme treatment.

    Abstract Boedijn, A.T., Kals, J. en Appelman, W. Peer Reviewers: Van Os, E., Raaphorst, M. en Kuipers, N., november 2022,

    In deze whitepaper wordt ingegaan op de ontwikkeling van cross-overs: verbindingen tussen ketens waarin uitgaande reststromen van het ene systeem verwaard worden tot grondstoffen voor een ander systeem. Specifiek wordt hier gekeken naar de potentie van een cross-over tussen de glastuinbouw en aquacultuur sectoren. Het onderzoeken van cross-overs tussen teeltsystemen en/of industriële processen is een van de verkenningsroutes in de transitie naar kringlooplandbouw; een essentiële bouwsteen voor een circulaire economie.

    Abstract Dover sole (Solea solea) which are farmed in an aquaculture system such as sea ranching show a slower growth rate and the system has a lower productivity than expected from sole living in a more natural marine environment. The addition of a source of heme and optionally a source of vitamin B12 to the diet of the fish results in an increase in daily growth rate and therefore an increase in productivity of a fish farming or ranching system. The addition or heme and vitamin B12 to the diet has the effect of reducing an anaemic growth suppressing effect of normal commercial fish food diets on sole. Medicaments for fish for preventing or treating anaemia and to increase haematocrit and haemoglobin include heme and optionally also vitamin B12.
