    Exceptional human longevity is associated with a specific plasma phenotype of ether lipids

    A lipid profile resistant to oxidative damage is an inherent trait associated with animal lifespan. However, there is a lack of lipidomic studies on human longevity. Here we use mass spectrometry based technologies to detect and quantify 137 ether lipids to define a phenotype of healthy humans with exceptional lifespan. Ether lipids were chosen because of their antioxidant properties and ability to modulate oxidative stress. Our results demonstrate that a specific ether lipid signature can be obtained to define the centenarian state. This profile comprises higher level of alkyl forms derived from phosphatidylcholine with shorter number of carbon atoms and double bonds; and decreased content in alkenyl forms from phosphatidylethanolamine with longer chain length and higher double bonds. This compositional pattern suggests that ether lipids from centenarians are more resistant to lipid peroxidation, and that ether lipid signature expresses an optimized feature associated with exceptional human longevity. These results are in keeping with the free radical theory of aging.We acknowledge funding from the Spanish Ministry of Education and Science (ref.

    Quality of goats milk cheese as affected by coating with edible chitosan-essential oil films

    Full text link
    [EN] The effectiveness of applying chitosan coatings containing rosemary and oregano essential oils to cheeses was analysed. Cheeses were coated by immersing the samples two or three times successively in the different formulations. The ripening indexes, water loss, fungal growth and sensory properties of the coated and noncoated cheeses throughout ripening were evaluated. The coatings both prevented weight loss and improved the microbial safety. The lipolytic and proteolytic activities were reduced in coated cheese, which is in line with the antimicrobial effect of active coatings. Sensory evaluation revealed that the cheeses double-coated with chitosan oregano oil were the best evaluated in terms of aroma and flavour.The authors wish to acknowledge the financing of the project by the Program of Support for Research and Development (PAID-05-12) of the Universitat Politecnica de Valencia.Cano Embuena, AI.; Cháfer Nácher, MT.; Chiralt, A.; Molina Pons, MP.; Borràs Llopis, M.; Beltrán Martínez, MC.; González Martínez, MC.

    Strategies to reengage patients lost to follow up in HIV care in high income countries, a scoping review

    Get PDF
    Background: Despite remarkable achievements in antiretroviral therapy (ART), losses to follow-up (LTFU) might prevent the long-term success of HIV treatment and might delay the achievement of the 90-90-90 objectives. This scoping review is aimed at the description and analysis of the strategies used in high-income countries to reengage LTFU in HIV care, their implementation and impact. Methods: A scoping review was done following Arksey & O'Malley's methodological framework and recommendations from Joanna Briggs Institute. Peer reviewed articles were searched for in Pubmed, Scopus and Web of Science; and grey literature was searched for in Google and other sources of information. Documents were charted according to the information presented on LTFU, the reengagement procedures used in HIV units in high-income countries, published during the last 15 years. In addition, bibliographies of chosen articles were reviewed for additional articles. Results: Twenty-eight documents were finally included, over 80% of them published in the United States later than 2015. Database searches, phone calls and/or mail contacts were the most common strategies used to locate and track LTFU, while motivational interviews and strengths-based techniques were used most often during reengagement visits. Outcomes like tracing activities efficacy, rates of reengagement and viral load reduction were reported as outcome measures. Conclusions: This review shows a recent and growing trend in developing and implementing patient reengagement strategies in HIV care. However, most of these strategies have been implemented in the United States and little information is available for other high-income countries. The procedures used to trace and contact LTFU are similar across reviewed studies, but their impact and sustainability are widely different depending on the country studied
