ABSTRACT

Background-Objective: With recent evidence suggesting that growth is no longer considered a major issue in children with food allergies (FA) on elimination diet, priority has shifted to diet quality to establish healthy eating patterns and prevent non-communicable diseases. The Diet Quality Index - International (DQI-I) could be useful for assessing the overall diet quality of FA-children. This study aimed to evaluate the impact of elimination diet on DQI-I in children with FA and the accuracy of DQI-I in reflecting nutrient intake. Materials-methods: In a prospective, cross-sectional, cohort study of FA-children (2-14 years), nutritional intake was evaluated using a 7-day food frequency questionnaire, 24-h dietary recall, and the DQI-I. Results: Of the 76 children recruited, 44.7% had multiple allergies. Mean overall DQI-I score was 52 points, with only 28% of participants having good overall DQI-I (≥60 points). DQI-I moderation and balance were the most affected domains. Participants with multiple allergies had higher DQI-I moderation and balance and lower vitamin D and Ca intake. Compared to toddlers, schoolchildren had higher DQI-I variety and lower moderation and received higher vitamin B2, vitamin B12, Ca, P, and Zn. The number of allergies, age, and milk avoidance were independently associated with adjusted DQI-I moderation and balance, energy, and certain micronutrient intake. Higher percentages of participants with good DQI-I received adequate amounts of Mn and vitamins A, B6, C, and folate than those with poor DQI-I. Conclusions: In children with FA on elimination diet, the DQI-I accurately captured the deflection of diet quality related to the development of chronic, non-communicable diseases through its moderation and balance components. This is DQI-I's main purpose as a healthy diet indicator and as such it would be a useful tool responding to the needs of the contemporary shifting of priorities in FA-children's diet from quantity to quality. Nevertheless, it does not accurately reflect the intake of certain micronutrients potentially compromised by elimination diets. Therefore, regular nutritional assessment utilizing both the DQI-I and tools assessing individual nutrient intakes along with professional nutrition counseling should be integral parts of the individualized management of children with FA to ensure adequate nutrient intake and establish healthy dietary patterns.

ABSTRACT

BACKGROUND: ω-3 polyunsaturated fatty acids (n-3 PUFAs) are reported to have beneficial effect on bone mineral density. This study aimed to evaluate early changes of bone turnover biomarkers in very low-birth-weight (VLBW) neonates and the effect of 2 parenteral lipid emulsions (PLEs) with different PUFA composition. METHODS: This is a randomized double-blind study with parallel design. VLBW neonates (n = 66) receiving parenteral nutrition (PN)>70% of daily energy requirements for >14 days were assigned into 2 groups that were prescribed soybean oil-based (n = 35) and n-3-enriched PLE (n = 31), respectively. Osteoprotegerin (OPG), soluble receptor activator of nuclear factor-kB ligand (sRANKL), osteocalcin (OC), interleukin-6 (enzyme-linked immunoblot assay kits), Ca, and P plasma levels were assessed before PLE implementation (T1) and on day 20 of life (T2). RESULTS: In the total population, sRANKL and OC significantly increased, whereas OPG and the OPG/sRANKL ratio decreased from T1 to T2. Within each group, T1-to-T2 changes of OC were significant in both groups, whereas those of OPG/sRANKL were significant only in the soybean-based group. Multiple regressions showed an independent effect of group allocation on OPG change. Significant associations were observed between PN duration and sRANKL change (negatively), n-6/n-3 and OC changes (positively), and OPG and sRANKL changes (positively). CONCLUSIONS: A high bone-turnover rate in VLBW neonates with predominance of bone resorption is confirmed. The lower rate of OPG/sRANKL reduction in the n-3-enriched PLE group indicates that n-3 PUFA-enriched PLEs may help to attenuate early bone loss in VLBW neonates.

ABSTRACT

Dietary patterns may have a role in the prevention of functional gastrointestinal disorders (FGIDs). The current study aimed at examining the association between FGIDs and adherence to the Mediterranean diet (MD) among elementary school children (ESC), as well as high school students (HSS). In a prospective cohort study, data from 1116 subjects (387 ESC and 448 HSS) aged 6-18 years were collected. FGID identification was based on the Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III (QPGS-RIII). Adherence to the MD was assessed using the KIDMED Index. Full data were available on 835/1116 questionnaires. Based on Rome III criteria, 184/835 participants (22%) were identified with FGID (122 (66%) with functional constipation (FC)). The prevalence of FGIDs (p = 0.001) was significantly higher in HSS (13-18 years). The KIDMED score in the cohort was 5.7 ± 2.5. Subjects with FGIDs demonstrated a lower KIDMED score compared to the non-FGID group, both in the cohort, as well as in the ESC and HSS subgroups (FGID vs. non-FGID: p = 0.001, p = 0.007, and p = 0.032, respectively). Multivariate analysis highlighted the KIDMED score as a significant predictor of FGIDs and FC after controlling for the age subgroups. We conclude that good adherence to the MD is associated to lower prevalence of FGIDs, while adolescents display a significantly higher prevalence of FGIDs compared to children.

ABSTRACT

BACKGROUND & AIMS: Little is known about the prevalence of functional gastrointestinal disorders (FGIDs) in children from the Mediterranean area of Europe. We aimed to assess the prevalence of FGIDs in children and adolescents in this region. METHODS: We collected data on 13,750 children (4-18 years old) enrolled in the Mediterranean-European Area Project, a school-based health study performed in Croatia, Greece, Israel, Italy, Jordan, Lebanon, Macedonia, Serbia, and Spain. Data were collected from March to June and in September of 2016. We analyzed data from 6602 students 4 to 10 years old (group A; mean age, 7.7 ± 1.9 y), and 7148 subjects 11 to 18 years old (group B; mean age, 13.8 ± 2.1 y). Children with FGIDs were identified based on answers to questionnaires on pediatric gastrointestinal symptoms, selected based on Rome III criteria. RESULTS: In group A, the prevalence of FGIDs was 20.7%. The most frequent disorders were functional constipation (11.7%), irritable bowel syndrome (IBS, 4%), aerophagia (3.5%), and abdominal migraine (3.1%). The prevalence of abdominal migraine was significantly higher in girls than in boys (P = .007). In group B, the overall prevalence of FGIDs was 26.6%. The most frequent disorders were functional constipation (13.1%), abdominal migraine (7.8%), aerophagia (6.3%), and IBS (5.6%). In group B, FGIDs had a higher prevalence among girls than boys (P < .001). In both groups, we found significant differences in the prevalence of specific disorders among specific countries. CONCLUSIONS: In an analysis of data on children 4 to 18 years old from the Mediterranean-European Area Project, we found FGIDs to be more frequent in girls. Functional constipation, aerophagia, abdominal migraine, and IBS are the most common disorders. However, the prevalence of FGIDs varies significantly among countries.

ABSTRACT

BACKGROUND: Insulin Growth Factor Binding Protein 4 (IGFBP-4), Stanniocalcin-2 (STC-2) and Pregnancy-Associated Plasma Protein-A (PAPP-A) have a well-documented involvement in several physiological functions in humans but predictors of their circulating levels remain largely unknown. We aimed to identify anthropometric and biochemical parameters associated with circulating levels of IGFBP-4/STC-2/PAPP-A axis (ISPa) cross-sectionally and to study their day-night variation and their regulation in response to mixed meal and exercise. METHODS: One hundred twenty two healthy individuals were evaluated cross-sectionally. Subgroups were subjected to standardized mixed meal ingestion in increasing quantities of 125mL or 250mL, or aerobic exercise for 30min, or day-night rhythm study. Main outcome measurements were circulating IGFBP-4 (total and intact), STC-2 and PAPP-A levels. RESULTS: In multivariate models, the main predictors of serum total IGFBP-4 were PAPP-A and female gender. Intact IGFBP-4 was positively associated with serum creatinine. Height was inversely and female gender and % of total body fat were positively correlated with STC-2. PAPP-A decreased after ingesting both the 125mL (p=0.03) and 250mL quantities (p=0.001), while total IGFBP-4 was reduced after the 250mL quantity (p=0.001). Exercise increased STC-2 and PAPP-A levels (p<0.001 for both). Intact, and to a lesser extent total, IGFBP-4 displayed a cortisol-like day/night variation. CONCLUSIONS: We report for the first time anthropometric and physiological modulators of ISPa serum levels in healthy humans.

ABSTRACT

PURPOSE: Follistatin may affect lean and fat mass and be implicated in metabolic diseases. We aimed to elucidate physiological predictors of circulating follistatin variation in healthy young humans. PROCEDURES: This was an observational, cross-sectional study with two additional prospective observational arms (circadian, seasonal sub-studies) and one prospective interventional arm (mixed meal sub-study). Healthy, young individuals of both sexes (n=122) were subjected to anthropometric and body composition measurements and their eating and exercise behavior profiles were assessed by validated questionnaires. Sub-groups were subjected to standardized meal ingestion (n=36), day-night rhythm (n=20) and seasonal variation (n=20) studies. Main outcome of the study were circulating follistatin levels. RESULTS: At baseline follistatin levels were correlated with creatinine (r=0.24; p=0.01), creatine phosphokinase (rs=0.22; p=0.02), and with lean body mass (rs=0.19; p=0.04) and were higher in males than females (p=0.004) after adjustment for leptin, which was its major predictor. Follistatin levels showed a circadian (p<0.001), but not a seasonal, variation, and were also affected by the phase of menstrual cycle in females (p=0.034). Follistatin levels were not affected by dietary or exercise habits but levels increased after a standardized meal ingestion (250kcal) (p=0.002). CONCLUSIONS: In healthy young individuals circulating follistatin levels are correlated with muscle mass. Follistatin levels are associated with circulating leptin levels and display a day-night rhythm and a menstrual cycle, but not a seasonal, variation.

ABSTRACT

OBJECTIVES: To evaluate Greek pharmacists' willingness to use a new Web-based software program to detect drug-food interactions, to assess the experience of those pharmacists opting to use the program, and to estimate the public benefit associated with use of the program. PRACTICE INNOVATION AND RESULTS: The Nutrition-Drug Interaction program was developed to enable Greek pharmacists to access an online database of medication-related information, including detailed drug and pharmaceutical company listings, nutritional guidelines for patients, potential drug-food and drug-drug interactions, and reaction alerts. More than 50% of the community pharmacists agreeing to use the program found it "quite useful" or "very useful," with more than 62% saying they were "very satisfied" or "quite satisfied" with the quality of information provided through the program. CONCLUSION: A significant proportion of Greek pharmacists, especially those 50 years of age or younger, found a new Web-based drug-food interaction software program to be both informative and useful. Participating pharmacists reported that use of the new program enhanced their role as health consultants and helped improve the quality of the patient services they provide.

ABSTRACT

CONTEXT: The myokine irisin may increase energy expenditure and affect metabolism. OBJECTIVE: The objective of the study was to elucidate predictors of irisin and study whether circulating irisin may have day-night rhythm in humans. DESIGN: This was an observational, cross-sectional study with an additional 24-hour prospective observational arm (day-night rhythm substudy) and two prospective interventional arms (mixed meal substudy and exercise substudy). SETTING: The study was conducted at the Hellenic Military School of Medicine (Thessaloniki, Greece). PATIENTS AND INTERVENTIONS: One hundred twenty-two healthy, young individuals were subjected to anthropometric and body composition measurements, and their eating and exercise behavior profiles were assessed with validated questionnaires. Subgroups were subjected to day-night rhythm, standardized meal ingestion, and 30-minute aerobic exercise studies. MAIN OUTCOME MEASURES: Circulating irisin levels were measured. RESULTS: Ιrisin levels were lower in males than females (P = .02) after adjustment for lean body mass, which was its major determinant. Irisin levels followed a day-night rhythm (P < .001) with peak at 9:00 pm. Irisin levels were increased at the end of exercise (84.1 ± 10.0 vs 105.8 ± 14.3 ng/mL; P < .001). Irisin levels were not affected by intake of a standardized meal and were not associated with caloric intake or diet quality. CONCLUSIONS: In healthy, young individuals, circulating irisin displays a day-night rhythm, is correlated with lean body mass, and increases acutely after exercise.

ABSTRACT

AIM: Evaluation of the prevalence of coeliac disease (CD) in Greek paediatric population. METHODS: The project consists of two parts: (i) a pilot study of preschool children aged 2-6 years to test the feasibility and diagnostic accuracy of community-based screening and (ii) a CD prevalence study, by random clustered sampling and proportionate stratification of various geographical areas in Greece. Trained nonmedical staff performed a rapid immunochromatographic test to detect IgA antibodies to tTG-IgA and IgA deficiency. Toddlers with positive results were referred to a paediatric gastroenterologist for further assessment with serum anti-tTG IgA and EMA-IgA. Children with positive serum anti-tTG and anti-EMA underwent upper gastrointestinal tract endoscopy and small bowel biopsy and were subsequently in gluten-free diet. RESULTS: In this project participated 1136 toddlers, who were tested at school. The prevalence of positive rapid anti-tTG screening was 1:154, of IgA deficiency 1:120 and of biopsy-proven CD 1:154. The prevalence of CD from this pilot study served as expected prevalence value for sample size calculation for the main prevalence study. CONCLUSION: This protocol using rapid immunochromatographic test for the detection of both IgA deficiency and CD is easy to be performed by nonmedical staff in a community setting, enabling the accurate identification of new CD cases among asymptomatic population.
