Comparative assessment of erythrocyte sphingolipid levels as potential cardiovascular health markers in women from Libya and Serbia: a small-scale study.

Aim: Cardiovascular diseases (CVDs) represent the major cause of morbidity and mortality worldwide including Libya, where they account for 43% of all deaths. Sphingolipids are involved in the pathology of numerous diseases including cardiovascular diseases and are proposed as potential biomarkers of cardiovascular health that could be more effective compared to traditional clinical biomarkers. The aim of this study was to determine the sphingolipid content in the erythrocyte membrane of Libyan migrant and Serbian resident women. In addition, to examine if sphingolipid levels could be used as a novel indicator of cardiovascular risk, we evaluated possible correlations with some well-established biomarkers of cardiovascular health.Materials and Methods: A total of 13 Libyan and 15 Serbian healthy women participated in the study. The high-performance version thin-layer chromatography (HPTLC) using the image analysis tool JustTLC was applied for quantification of erythrocytes' sphingolipids.Results: Lower mean values of erythrocytes' sphingolipids and cholesterol concentrations were found in the group of Libyan emigrants compared to Serbian resident women. Besides, in this group of apparently healthy women (n = 28), the sphingolipid content of erythrocytes was inversely related to the Omega-3 index (r =-0.492, p = 0.008) and directly linked to vitamin D status (r = 0.433, p = 0.021) and membrane cholesterol levels (r = 0.474, p = 0.011).Conclusion: The erythrocytes' sphingolipid levels should be measured/assessed as an additional biomarker of CV health, by applying a simple and routine method. Still, further investigation in a larger population-specific context is warranted.

Underutilized plants increase biodiversity, improve food and nutrition security, reduce malnutrition, and enhance human health and well-being. Let's put them back on the plate!

The global food system depends on a limited number of plant species. Plants with unsatisfactory nutritional value are overproduced, whereas the wide variety of nutrient-rich plant species used in earlier times remains neglected. Basing our diet on a few crops has wide-ranging negative consequences on nutrition and food security. Although still under-researched, underutilized plants are slowly starting to receive increased recognition. These plants have superior nutritional content and immense potential to contribute to food and nutrition security and increased sustainability. This narrative review provides evidence to encourage the promotion, domestication, and commercialization of underutilized plants. The anti-inflammatory, antidiabetic, and anticancer effects of some of underutilized plants are presented in this review. The outstanding ability of forgotten plants to increase food and nutrition security, boost dietary diversity, reduce malnutrition, and enhance human health and well-being is demonstrated. The main barriers and obstacles to reintroducing underutilized foods are reviewed and recommendations for overcoming nutrition and dietary-related challenges for re-establishing underutilized plants into the global food system are presented. The expansion of underutilized plants for human use is of paramount importance. The exceptional nutritional properties, bioactive potential, and proven health benefits of underutilized plants indicate that increased promotion, domestication, and commercialization of these plants should be strongly supported. Besides health benefits, marginalized plants have the potential to enhance human well-being and improve people's lives in many ways, retain biodiversity, and develop local economies. Therefore, underutilized plants should be used in the broader context of well-balanced and healthy diets.

Implementation of Harmonized Food Consumption Data Collection in the Balkan Region According to the EFSA EU Menu Methodology Standards.

Initiatives in the Capacity Development in Nutrition Research in the Balkan region in the last decade have been toward the creation of contemporary, harmonized Research Infrastructure (RI) compliant with European standards. This study describes the process of creation and implementation of the European Food Safety Authority (EFSA) EU Menu methodology in the Balkan region during the EFSA support projects for food consumption data collection in four countries (Serbia, Montenegro, Bosnia and Herzegovina, and North Macedonia). This process entailed the application and improvement of an innovative tool, the DIET ASSESS and PLAN (DAP), a platform for standardized food consumption data collection and dietary intake assessment. DAP comprises computerized food consumption, anthropometric measurements, and physical activity questionnaires, validated food picture book, and FoodEx2 exposure hierarchy with sets of facet descriptors of the interest. It hosts the Balkan food platform with a Serbian food composition database (FCDB) and Regional FCDB, compliant with European Food Information Resource (EuroFIR™) standards. The implementation of the DAP platform in national dietary surveys conducted with the support of the EFSA EU Menu project in Balkan countries enabled harmonized food consumption data compilation and reporting. Application of the methodology entailed the development of study protocol and extensive education and training of study personnel. The entire data collection process was managed by internal and external survey coordinators. A pilot study was conducted to test the entire data collection and control process and was afterward used to make necessary improvements and adjustments to meet EU Menu requirements. Data collected are internationally comparable with food consumption data in other European countries within the framework of the EU Menu program. The existence of such data in the Balkan region will catalyze research activities in emerging topics, such as identification of dietary patterns, the establishment of national nutrient reference values and food-based dietary guidelines (not only in Serbia, but in the whole Balkan region), dietary exposure assessments, the endorsement and evaluation of new food legislations, the environmental and other effects of diet on the food system. The developed and implemented methodology underpins evidence-based policy-making processes lacking in the field of public health nutrition in the region.

Improving nutrition surveillance and public health research in Central and Eastern Europe/Balkan Countries using the Balkan Food Platform and dietary tools.

The objective of this paper is to share experience and provide updated information on Capacity Development in the Central and Eastern Europe/Balkan Countries (CEE/BC) region relevant to public health nutrition, particularly in creation of food composition databases (FCDBs), applying dietary intake assessment and monitoring tools, and harmonizing methodology for nutrition surveillance. Balkan Food Platform was established by a Memorandum of Understanding among EuroFIR AISBL, Institute for Medical Research, Belgrade, Capacity Development Network in Nutrition in CEE - CAPNUTRA and institutions from nine countries in the region. Inventory on FCDB status identified lack of harmonized and standardized research tools. To strengthen harmonization in CEE/BC in line with European research trends, the Network members collaborated in development of a Regional FCDB, using web-based food composition data base management software following EuroFIR standards. Comprehensive nutrition assessment and planning tool - DIET ASSESS & PLAN could enable synchronization of nutrition surveillance across countries.

Professional training in nutrition in Central and Eastern Europe: current status and opportunities for capacity development.

OBJECTIVE: To examine the availability of academic programmes in nutrition and identify nutrition training needs in Central and Eastern Europe (CEE). DESIGN: A questionnaire with close-ended and open-ended questions was distributed to the members of the United Nations University Standing Committee on Nutrition, Regional Network for Capacity Development in Nutrition in CEE (NCDN CEE). SETTING: Participants' responses to the questionnaire including the comments of their colleagues from home institutions were obtained in group discussions during NCDN CEE meetings in 2010-2013. SUBJECTS: Sixteen CEE countries' experts and their colleagues from home institutions involved in NCDN CEE activities 2007-2013. RESULTS: The responses were obtained from fourteen out of sixteen participating countries; five countries have established Bachelor, Master and PhD studies in nutrition (Croatia, Czech Republic, Poland, Slovak Republic and Slovenia), whereas in Latvia and Republic of Macedonia only Bachelor and Master studies are set up. Seven countries have no Bachelor, Master or PhD studies: Bosnia and Herzegovina, Bulgaria, Estonia, Lithuania, Montenegro, Romania and Serbia. Introduction to data analysis and Nutritional epidemiology are the most needed nutrition trainings that would increase working competence of nutritionists and nutrition-related professionals in CEE. CONCLUSIONS: Availability of academic programmes in nutrition in CEE countries is limited. Opportunities for improving the competence of existing and future nutrition-related professionals should be addressed at national and regional level; distance learning courses and creation of a regional centre for nutrition training were seen as opportunities for sustainable capacity development in nutrition in CEE.

Distribution of plasma fatty acids is associated with response to chemotherapy in non-Hodgkin's lymphoma patients.

Our recent data have linked plasma phospholipid fatty acid (FA) profile in patients with non-Hodgkin's lymphoma (NHL) with the clinical stage and aggressiveness of the disease. Thus, we proposed that plasma FA status in these patients may influence the effect of chemotherapy. The aim of this work was to assess FA status in NHL patients undergoing chemotherapy in relation to their response to therapy. We analyzed plasma FA profile in 47 newly diagnosed NHL patients before chemotherapy, after 3 cycles and after the end of the planned chemotherapy. Patients were treated according to the hospital protocol: 28 patients with cyclophosphamide, doxorubicin, vincristine and prednisone, 7 with other anthracycline-containing regimens, 4 patients with cyclophosphamide, vincristine and prednisone and 8 with fludarabine-based regimens. Rituximab was added in 22 patients. Ten patients who did not receive all planned chemotherapy due to death or toxicity (non-completers) had significantly lower (p < 0.05) baseline proportion of palmitoleic, linoleic, eicosapentaenoic and docosahexaenoic acid, as well as n-3 and n-6 FA, than the patients who completed chemotherapy (completers). Furthermore, the completers were divided according to the response to chemotherapy to complete remission (CR), stable disease and progressive disease (PD). Proportion of palmitic acid after the end of chemotherapy was the highest in the PD group, while stearic acid showed the opposite trend. Palmitoleic acid and all n-3 FA (18:3, 20:5, 22:5 and 22:6) were the highest in the patients in remission and the lowest in PD (p < 0.001). Linoleic acid decreased and arachidonic acid increased from the CR to the PD group (p < 0.001). These results suggest that aberrations in plasma FA may influence response to chemotherapy in patients with NHL.

Effects of n-3 Fatty Acids Supplementation on Plasma Phospholipids Fatty Acid Composition in Patients with Obstructive Jaundice- a Pilot Study.

Nutritional and immunological status of patients with obstructive jaundice is usually severely altered, with high mortality rates. The n-3 polyunsaturate fatty acids (PUFA), particularly eicosapentaenoic acid (EPA, 20:5 n-3), posess potent immunomodulatory activities. Thus, our aim was to compare the plasma phospholipid fatty acid (FA) composition of these patients with healthy subjects, as well as before and after 7 days preoperative supplementation with high doses of EPA (0.9 g per day) and docosahexaenoic acid (DHA, 22:6 n-3, 0.6 g per day). We found impaired FA status in obstructive jaundice patients, especially EPA, DHA and PUFA, but significantly increased content of total n-3 FA, 22:5 n-3 FA and particularly EPA, which increased more than 3 fold, after 7 days supplementation. In addition, the n6/n3 ratio significantly decreased from 14.24 to 10.24, demonstrating severely improved plasma phospholipid profile in these patients after the intervention.
