Se aborda el tema de lo global y lo local: el modelo neoliberal, la problemática de la pobreza a nivel mundial y la redefinición de las políticas sociales en la Argentina, en función de la coyuntura socioeconómica imperante. Ahí, las conceptualizaciones estigmatizantes sobre la "pobreza" y los "pobres" que dichas políticas emplean, no se corresponden con lo que sienten y piensan las personas con respecto a su situación de "pobreza". En este sentido se intenta abrir el debate y la reflexión crítica y conjunta sobre la intromisión de Occidente en el espacio del "otro"; intromisión que deviene en reducción del espacio: espacio que es físico, social y simbólico.

Nutritional status is an indicator of disease prognosis and survival. This study aimed at assessing the effectiveness of a self-management mobile app in supporting patients with CF to achieve the dietary goals set by the CF nutrition guidelines. A clinical trial was conducted in pancreatic insufficient children with CF, followed in six European CF centres, where the self-management app developed within the MyCyFAPP project was used for six months. To assess secondary outcomes, three-day food records were compiled in the app at baseline and after 3 and 6 months of use. Eighty-four subjects (mean 7.8 years old) were enrolled. Compared to baseline, macronutrient distribution better approximated the guidelines, with protein and lipid increasing by 1.0 and 2.1% of the total energy intake, respectively, by the end of the study. Consequently, carbohy...

Our aim is to evaluate the efficacy of the detection of gluten immunogenic peptides (GIP) in feces, to monitor in real life, the adherence to GFD in pediatric patients with CD. A cross-sectional, prospective study was conducted. Fecal samples from CD children were analyzed by a rapid immunochromatographic (IC) test and by an ELISA method, both based on the antigliadin 33-mer monoclonal antibody. Group 1 comprises 43 children on a GFD. According to the food records (FR), 39/43 patients were compliant with the GFD and gluten consumption was recorded in 4. GIP were detected in 15/43 individuals by the ELISA method and also in 7 by IC strips. Group 2: comprise 18 children at CD diagnosis; GIP levels decreased over time (p < 0.001) in a non-linear way (p = 0.028) after starting a GFD and were below the detection limit on the third day in most individuals. GIP were detected, both by ELISA and by IC strips, in CD patients on a GFD, in which no consumption of gluten had been registered on the FR, confirming GIP detection to be superior to FR discovering involuntary transgressions. Despite a positive correlation between the amount of gluten intake and the concentration of GIP in feces, the interindividual variations observed suggest gastrointestinal factors influencing GIP recovery need to be further investigated.

We aimed to investigate fCP concentrations in a larger population of healthy children aged 4–16 years to analyze more in depth the behavior of fCP in this age range and to determine if cut-off levels could be conclusively recommended. A prospective study was conducted to investigate fCP concentrations of healthy children aged 4–16 years. In 212 healthy children, the median and 95th percentile for fCP were 18.8 mg/kg and 104.5 mg/kg, respectively. We found a statistically significant association between the 95th percentile of fCP concentrations and age (p

A retrospective study of pediatric patients who underwent a CD serological markers study: EMA and anti-tissue transglutaminase antibodies (anti-TG2). Clinical symptomatology, degree of histological lesion, human leukocyte antigen (HLA) haplotype compatible with CD (HLA DQ2 and/or DQ8), and final diagnosis were taken into account. We included 445 patients who were classified in two groups according to the final diagnosis. Group 1: 232 children with CD, 91.4% of whom exhibited small intestinal villous atrophy, 228 being EMA-positive and four EMA-negative. Group 2: 213 children with a non-CD diagnosis, 212 EMA negative and one EMA positive. Both antibodies, EMA and anti-TG2, reached similar sensitivities, 98% and 99% respectively, while EMA had a higher specificity (99%) than anti-TG2 (93%). By using both markers combi...

Whey samples were analyzed for AGA-IgA by an indirect homemade ELISA and for total IgA (g/L) by a commercial ELISA kit. AGA-IgA was detected in BM, both in mothers on a GFD and mothers on a ND. AGA-IgA levels in both groups of mothers, CD and non-CD, show the same trend towards decreasing slightly along the months of lactation (p = 0.91). A different trend is observed for total IgA levels, decreasing markedly in CD mothers from the first month of lactation onwards but remaining stable in non-CD mothers (p = 0.048). A s...

Moreover, reference values for fecal eosinophil-derived neurotoxin (fEDN) in children have not been established. The aim of this study was to investigate fCP and fEDN levels in young healthy children in order to establish reference values. Stool samples were obtained from healthy children aged 0 to 12 years. fCP and fEDN levels were analysed using the EliA Calprotectin 2 assay (Phadia AB) and a novel research assay (on the ImmunoCAP platform), respectively. In the 174 included children (87 boys), 95 Percentile values ranged from 1519 mg/kg at 0 months to 54.4 mg/kg at 144 months for fCP and from 9.9 mg/kg at 0 months to 0.2 mg/kg at 144 months for fEDN. There was a statistically significant association between age and fCP concentrations (p < 0.001) and age and fEDN concentrations (p < 0.001). We also found a statistically significan...

The new olive cultivar 'Sikitita' was obtained from a cross between the 'Picual' and 'Arbequina' ... more The new olive cultivar 'Sikitita' was obtained from a cross between the 'Picual' and 'Arbequina' varieties. 'Sikitita' was selected for its features, making it particularly suited to high-density olive hedgerow orchards. From the standpoint of chloroplast pigment metabolism, the fruits of the 'Picual' and 'Arbequina' varieties have significant differences. It is therefore extremely interesting to analyze the descendants of both cultivars. With regard to chlorophyll catabolism, 'Sikitita' has proven to be a cultivar with low pigmentation and low levels of chlorophyllase activity. This is contrary to the findings obtained to date, where varieties with low pigmentation are a consequence of high chlorophyllase activity ('Arbequina') and highly pigmented fruits are due to low chlorophyllase activity ('Picual'). 'Arbequina' was, until recently, the only cultivar described that had developed a carotenogenic process, despite its anthocyanic ripening. However, from its father ('Arbequina'), the 'Sikitita' cultivar has inherited the pool of enzymes necessary to esterify xanthophylls at the chromoplast level. This makes 'Sikitita' a very interesting cultivar, with potential chemotaxonomic differences (such as esterified xanthophylls in the olive oils), and demonstrates the interest in genetic improvement programs for olive cultivars with different organoleptic characteristics.

The method consists of a pigment extraction in liquid phase and subsequent analysis by HPLC-DAD. The profile of chlorophyll pigments of an olive oil is determined essentially by its content in pheophytins (a and b), but in no case any copper derivative. Different samples of colorant E 141i have been analyzed, the natural coloring additives used to adulterate vegetable oils. The 99.59 (0.52% of the chlorophyll pigments present in the different samples of E 141i colorant are not those of an olive oil (more than 75% are cuproderivatives). Thus, the simple detection of one of the compounds in an olive oil indicates adulteration. The major chlorophyll derivative in all the E 141i colorants samples is Cu-pyropheophytin a and its limit of detection (LOD) defined at a signal-to-noise ratio of about 3 was 6.58 ng/g.

First, a high chlorophylls/carotenoids ratio and a low chlorophyll a/b ratio imply that the photosynthetic apparatus has structural differences with respect to other olive varieties; second, in the carotenoid fraction, a low percentage of lutein, a high percentage of β-carotene, and a high content in neoxanthin are signs that in these three olive varieties the carotenoid biosynthetic pathway is displaced, favoring the β,β series over the R,β series. These differences in the chlorophyll and carotenoid profiles of the fruit are reflected in the corresponding virgin olive oils. It is proposed that the limits of the pigmentary parameters of authenticity of virgin olive oil previously established for the Spanish varieties be extended to obtain markers at a general level, independent of the geographical origin.
