Comparison of the systemic and pulmonary inflammatory response to endotoxin of neutropenic and non-neutropenic rats

BACKGROUND: Neutrophil infiltration commonly occurs in acute lung injury and may be partly responsible for the inflammatory response. However, acute lung injury still occurs in the neutropenic host. The objectives of this study are to determine if inflammation and acute lung injury are worse in neutropenic versus the normal host after endotoxemia. METHODS: Rats were divided into four groups: 1) control, 2) neutropenic, 3) endotoxemic and 4) endotoxemic and neutropenic. Tumor necrosis factor (TNF)-α and macrophage inflammatory protein (MIP-2) were measured in the blood, lung lavage and for mRNA in the lung. Arterial blood gases were measured to determine the alveolar-arterial oxygen gradient which reflects on lung injury. RESULTS: In endotoxemia, the neutropenic rats had lower plasma TNF-α (116 ± 73 vs. 202 ± 31 pg/ml) and higher plasma MIP-2 (26.8 + 11.9 vs. 15.6 + 6.9 ng/ml) when compared to non-neutropenic rats. The endotoxemic, neutropenic rats had worse lung injury than the endotoxemic, non-neutropenic rats as shown by increase in the alveolar-arterial oxygen gradient (24 ± 5 vs. 12 ± 9 torr). However, lavage concentrations of TNF-α and MIP-2 were similar in both groups. CONCLUSION: Neutrophils may regulate TNF-α and MIP-2 production in endotoxemia. The elevation in plasma MIP-2 in the endotoxemic, neutropenic rat may be secondary to the lack of a neutrophil response to inhibit production or release of MIP-2. In endotoxemia, the severe lung injury observed in neutropenic rats does not depend on TNF-α or MIP-2 produced in the lung

Development and Sustainability of National Food Composition Databases for use in Dietary Monitoring and Public Health Nutrition in the Eastern Mediterranean Region

Background:Similar to Western Countries, the Eastern Mediterranean Region (EMR) also presents major public health issues associated with the increased consumption of sugar, fat (saturated fatty acids, trans fatty acids), salt. Therefore, one of the policies of the World Health Organization’s (WHO) EMRO is to reduce the intake of these, to address the risk of obesity and non-communicable diseases such as diabetes, cardiovascular disease and cancer. In order to do this, access to updated, standardized, harmonized food composition data (FCD) is essential. Aims: Objectives within this Medical Research Council GCRF project, working jointly with WHO–EMRO, are to assess the status of national FCD and to provide training and capacity development in the use of improved standardized methodologies to update FCD as well as dietary intake methods, use of suitable biomarkers of nutritional value and to determine health outcomes in the low- and middle-income countries (LMIC) of this region. By identifying specific regional needs for FCD compilation, detailed training workshops can be developed to enable the production of vital high-quality harmonised data in the EMR including: Iran, Iraq, Pakistan, Kuwait, Tunisia, Morocco, Sudan, Egypt, Jordan together with Mauritania. This capacity building will lead to the development and sustainability of up-to-date national and regional FCD for use in dietary monitoring assessment in food and nutrient intakes. Methods: Training needs were identified, and short-term scientific missions organized for researchers via training, knowledge exchange workshops and short-term exchange of researchers. Training at CAPNUTRA (Serbia) and INNTA (Tunisia) included the use of improved standardized methodologies for food composition and food intake for 7 EMR countries leading to development of national FCD, enabling upload onto the EuroFIR data platform. A 3-week training course on analytical methods was carried out at INSA (Portugal) for analysts from Egypt, Jordan and Sudan. Key findings: A total of 45 participants from 13 countries including 10 EMR and 3 invited West African countries attended 5 workshops and training exchanges. Training topics included: value documentation and quality assessment; food composition data tools (Food Composition And System Environment (FoodCASE), Diet assess and Plan (DAP), Nutritics; food classification and description of composite dishes, recipe calculation approaches; use of yield and retention factors; EuroFIR e-learning tools and case studies; laboratory food analysis (vitamins A, B1, B2, C, D2, D3 and E, fatty acids, amino acids, minerals, fibre); quality management system; food metrology principles; validation of chromatographic methods; and food label legislation. 6 countries have imported their FCD, as open access, into the EuroFIR FoodEXplorer platform. The WHO-EMRO jointly with MRC GCRF project funded and mobilized research institutions in over 10 countries, with more focus on identifying traditional dishes and micronutrients. Conclusions and project Implications: The use of improved standardized methodologies for food composition and dietary intake will produce robust measurements that will reinforce dietary monitoring and policy in LMIC. The capacity building from this project has led to searchable national food composition data from developing/emerging countries being made available in an open access form for the first time. WHO-EMRO, is funding further updates of FCD tables in Jordan, Lebanon, Oman, Sudan, Tunisia, Morocco, Pakistan, Iran Egypt, and UAE, with the focus on identifying TFA, SFA, salt and sugar in addition to micronutrients.Project supported by Global Challenges Research Funds (UK) and Medical Research Council (MR/R019576/1), is grateful to WHO EMRO.info:eu-repo/semantics/publishedVersio

Development and Sustainability of Eastern Mediterranean Region and South African National Food Composition Databases

Introduction: The World Health Organization’s (WHO)-Eastern Mediterranean Region Office (EMRO) aims to reduce the consumption of sugar, fat (saturated fatty acids, trans fatty acids) and salt; and decrease the risk of obesity and non-communicable diseases in the Eastern Mediterranean Region (EMR). To address this Quadram Institute Bioscience is working jointly with WHO-EMRO in providing training and capacity development to national experts, leading to standardized, harmonized, comprehensive, open access Food Composition Data (FCD) to underpin food and nutrition programs and policies in these low- and middle-income countries (LMIC). Materials and Methods: By identifying specific regional needs for FCD compilation, detailed training workshops were developed to enable the production of vital high-quality harmonised data in the EMR including: Iran, Iraq, Pakistan, Kuwait, Tunisia, Morocco, Sudan, Egypt, and Jordan. Training on standardized methodologies for food composition and dietary intake methods, biomarkers, analytical methods and FCD tools were provided by experts from UK, Serbia, Portugal and WHO-EMRO, via knowledge exchange workshops and short-term training exchange of researchers. Results: A total of 45 FCD expert compilers from 13 countries attended 2 workshops and 3 training exchanges. Knowledge transfer consisted of: value documentation; quality assessment; online food composition data tools; food classification and description of composite dishes; recipe calculation; yield and retention factors; and laboratory food analysis (vitamins A, B1, B2, C, D2, D3 and E, fatty acids, amino acids, minerals, fibre). FCD from 6 countries was standardized using the EuroFIR data template and Theasuri (standardised vocabularies). The final datasets from Iran, Iraq, Pakistan, Kuwait, Tunisia and Morocco were made available via FoodExplorer an innovative interface for FCD which allows users to search information from food composition data simultaneously across many countries. Discussion: The use of improved standardized methodologies for food composition and dietary intake will produce robust measurements that will reinforce dietary monitoring and policy in LMIC. The capacity building from this project has led to searchable national food composition data from LMIC being made available as open access form for the first time. WHO-EMRO, is funding further updates of FCD tables in Jordan, Lebanon, Oman, Sudan, Tunisia, Morocco, Pakistan, Iran, Egypt, and UAE, with the focus on identifying TFA, SFA, salt and sugar in addition to micronutrients.Project supported by Global Challenges Research Funds (UK) and Medical Research Council (MR/R019576/1), is grateful to WHO EMRO.info:eu-repo/semantics/publishedVersio

Vitamin D status in mothers with pre-eclampsia and their infants: a case-control study from Serbia, a country without a vitamin D fortification policy

Objective: The objective of the present study was to determine if vitamin D intake and status are associated with pre-eclampsia in a country without a vitamin D fortification policy. Design: A case-control study of pregnancies with (case) and without (control) pre-eclampsia was conducted from January to April when UVB is minimal. Maternal and cord blood obtained at delivery were measured for plasma 25-hydroxycholecalciferol (25-OH-D-3), 3-epimer of 25-OH-D-3 (3-epi-25-OH-D-3) and 24,25-dihydroxycholecalciferol (24,25-(OH)(2)D-3) by LC-MS/MS and maternal 1,25-dihydroxyvitamin D (1,25-(OH) 2D). Differences between groups were tested with ANOVA and Bonferroni post hoc tests (P lt 0.05). Setting: Clinical Center of Serbia. Subjects: Pregnant women with and without pre-eclampsia (n 60) and their infants. Results: Exogenous vitamin D intake (0.95-16.25 mu g/d (38-650 IU/d)) was not significantly different between groups. Women with pre-eclampsia delivered infants at an earlier gestational age and had significantly lower mean total plasma 25-hydroxyvitamin D (25-OH-D; case: 11.2 (SD 5.1); control: 16.1 (SD 5.7) ng/ml; P=0.0006), 25-OH-D-3 (case: 10.0 (SD 4.9); control: 14.2 (SD 5.8) ng/ml; P=0.002), 3-epi-25-OH-D-3 (case: 0.5 (SD 0.2); control: 0.7 (SD 0.2) ng/ml; P=0.0007) and 1,25-(OH)(2)D (case: 56.5 (SD 26.6); control: 81.0 (SD 25.7) pg/ml; P=0.018), while 24,25-(OH)(2)D-3 was not different between groups. Infants did not differ in total plasma 25-OH-D, 25-OH-D-3, 3-epi-25-OH-D-3 and 24,25-(OH)(2)D-3, but the mean proportion of 3-epi-25-OH-D-3 was higher in the infant case group (case: 7.9 (SD 1.1); control: 7.0 (SD 1.4) % of total 25-OH-D-3; P=0.005). Conclusions: A high prevalence of vitamin D deficiency, as defined by plasma 25-OH-D lt 12 ng/ml, was observed in 47 % of all mothers and 77 % of all infants. These data underscore the need for prenatal vitamin D supplementation and a food fortification policy in Serbia

Validity of an FFQ assessing the vitamin D intake of young Serbian women living in a region without food fortification: the method of triads model

Objective: The objective of the present study was to examine the external validity of an FFQ designed to estimate dietary vitamin D intake compared with a plasma biomarker and three repeated 24 h dietary recalls in women of reproductive age in Serbia, where there is no exposure to food fortified with vitamin D. The method of triads was applied. Design: In a cross-sectional study, 422 women completed the Women and Reproductive Health FFQ (WRH-FFQ) during the winter months. From a representative subgroup (n 44), three 24 h dietary recalls and anthropometric parameters were collected as well as a fasting blood sample for vitamin D biomarker analyses. Correlation coefficients were calculated between each of the dietary methods. Validity coefficients, as a correlation between the measured and estimated 'true' exposure, were calculated using the method of triads. Bland-Altman plots were also constructed. Setting: Three major universities in Serbia. Subjects: Healthy young women (n 422) aged 18-35 years. Results: The WRH-FFQ estimate of vitamin D intake for all participants was 4.0 (SD 3.3) mu g/d and 3.1 (SD 2.3) mu g/d for the subgroup. Bland-Altman plots for these intakes showed high agreement. Validity coefficients for the FFQ, 24 h recall and biomarker were. rho(QI) = 0.847 (95 % CI 0.564, 0.928), rho(RI) = 0.810 (95 % CI 0.537, 0.997) and rho(BI) = 0.499 (95 % CI 0.190, 0.840), while the correlation coefficients were 0.686, 0.422 and 0.404. Conclusions: The FFQ applied in the present study is a valid tool for assessing dietary vitamin D intake in women living in Serbia, a region without mandatory vitamin D food fortification

Assessment of vitamin D intake among Libyan women - adaptation and validation of specific food frequency questionnaire

Vitamin D deficiency (VDD) has pandemic proportions worldwide. Numerous studies report on high prevalence of VDD in sunny regions like Near East and North Africa (NENA). Previous studies indicated that Libyan population was at risk of VDD. To contribute to the body of evidence, measurement of vitamin D status on children, adults, in Misurata region was conducted, and confirmed with validated dietary intake study. Serum 25(OH)D was analysed using electrochemiluminescence protein binding assay. Existing Food Frequency Questionnaires (FFQ) were adapted to Libyan Women Food Frequency Questionnaire (LW-FFQ). Repeated 24h dietary recalls and LW-FFQ were employed in vitamin D intake evaluation. LW-FFQ was validated using 24h dietary recall and vitamin D status as referent methods. The questionnaires included anthropometry and lifestyle information. Vitamin D status assessment revealed inadequate levels (25(OH)D lt 50nmol/l) in almost 80% of participants. Women (25-64y) were identified as the most vulnerable group with vitamin D inadequacy present in 82% (61.6% had 25(OH)D lt 25nmol/l, and 20.2% had 25-50nmol/l 25(OH)D). Average Vitamin D intake within the study sample (n=316) was 3.9 +/- 7.9 mu g/d, with 92% participants below both Institute of Medicine (IOM) (10 mu g/d) and European Food Safety Authority (15 mu g/d) recommendations. Measured vitamin D status, in 13% of this group, correlated significantly (p=0.015) with intake estimates. Based on self-report, consumption of vitamin D supplements does not exist among study participants. Additional lifestyle factors influencing vitamin D status were analysed. Only 2% of study participants spend approximately 11 min on the sun daily, 60.4% were obese, 23.1% were overweight and 71.2% reported low physical activity. These findings confirm previous reports on high prevalence of VDD in women across NENA, and in Libya. The situation calls for multi-sectoral actions and public health initiatives to address dietary and lifestyle habits

Mouse alpha 1-protease inhibitor is not an acute phase reactant

Mouse plasma contains two major protease inhibitors, alpha 1-protease inhibitor (alpha 1-PI) and contrapsin, which have high affinity for bovine trypsin. Systemic injury, such as turpentine-induced inflammation, did not change the plasma concentration of alpha 1-PI, but increased that of contrapsin by 50%. The concentration of hepatic alpha 1-PI mRNA was determined by Northern blot hybridization and was not significantly affected by the acute phase reaction. J.M. Frazer, S.A. Nathoo, J. Katz, T.L. Genetta, and T.H. Finley [1985) Arch. Biochem. Biophys. 239, 112-119) have reported a threefold increase of mRNA for the elastase specific alpha 1-PI but this increase was not demonstrated by the present study. The mRNAs for known mouse acute phase plasma proteins were, however, stimulated severalfold by the same treatment. These results indicate that in the mouse, as opposed to human, alpha 1-PI is not an acute phase reactant
