Nutritional management and weight changes during hospitalization of Brazilian infants with diarrhoea: Primary reliance on oral feeding or continuous nasogastric drip with locally made, modulated minced chicken formula

The nutritional management of infants admitted with diarrhoea to the University Hospital of Botucatu includes a change from bolus feeding of a modulated minced-chicken formula to a continuous nasogastric drip (NGD) feeding, whenever the required calorie intake is not achieved or the diarrhoea does not subside. To evaluate this approach, the clinical course and weight changes of 63 children, aged 1-20 months, were reviewed; most (81 per cent) were below the third percentile for weight at admission and 76 per cent had a total duration of diarrhoea ≥10 days. Associated infections, mainly systemic, were present at or after admission in 70 per cent of them. Twenty-five survivors needed nutritional support (NS), predominantly NGD, for a median duration of 30 per cent of their admission time, and were compared to 31 survivors managed without NS. Those who necessitated NS lost weight for a significantly longer median time (12x4 days, p<0.005), but their total weight loss was similar (5x4 per cent) as well as diarrhoea's duration (8x7 days). There was a tendency for a longer hospitalization (21x16 days 0.05onger span to begin weight gain after diarrhoea's end for the group with NS (p<0.05), but subsequent growth quotient and daily weight gain during admission were similar for both groups. Both groups of survivors received similar amounts of energy, although the initial increase was delayed for those who needed the NGD. Seven infants (11 per cent) died, most of overwhelming infection, and presented a high total weight loss, albeit receiving NS for 71 per cent of their admission's time. It was concluded that feeding diarrhoeic infants with a NGD when necessary, possibly prevented a greater nutritional insult for the survivors. The NGD can be safely employed and should be valued, provided weight losses are carefully monitored in order to detect infants at highest risk.

Discovery and Pharmacological Characterization of a Novel Small Molecule Antagonist of Integrin α4β1: Focus on Antiallergic Activity

Allergy is a common hypersensitivity disorder that affects 15% to 20% of the population and its prevalence is increasing worldwide. Its severity correlates with the degree of eosinophil infiltration into the conjunctiva, which is mediated by chemokines that stimulate the production of adhesion molecules like intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) on the endothelial cell surface. The α4β1 and α4β7 integrins are expressed in eosinophils and contribute to their activation and infiltration in AC through the binding to VCAM-1 or fibronectin, expressed on vascular endothelial cells. Blockade of α4 integrins might be a therapeutical achievement in allergic eye diseases. DS 70, that show an IC50 in the nanomolar range against α4β1 integrin in Jurkat cells and in the eosinophilic cell line EOL-1. This compound was able to prevent cell adhesion to VCAM-1 and FN in vitro. In a scintillation proximity assay DS70 displaced 125I-FN binding to human α4β1 integrin and, in flow cytometry analysis, it antagonized the binding of a primary antibody to α4β1 integrin expressed on the Jurkat cells surface as well. Furthermore, we analysed also its effects on integrin α4β1 signalling. In an vivo model of allergic conjunctivitis, topical DS70 reduced the clinical aspects of EPR (early phase reaction) and LPR (late phase reaction), by reducing clinical score, eosinophil accumulation, mRNA levels of cytochines and chemochines pro-inflammatory and the conjunctival expression of α4 integrin. In conclusion, DS70 seems a novel antiallergic ocular agent that has significant effects on both early and late phases of ocular allergy.

Genetic diversity among horse populations with a special focus on the Franches-Montagnes breed

Genetic characterization helps to assure breed integrity and to assign individuals to defined populations. The objective of this study was to characterize genetic diversity in six horse breeds and to analyse the population structure of the Franches-Montagnes breed, especially with regard to the degree of introgression with Warmblood. A total of 402 alleles from 50 microsatellite loci were used. The average number of alleles per locus was significantly lower in Thoroughbreds and Arabians. Average heterozygosities between breeds ranged from 0.61 to 0.72. The overall average of the coefficient of gene differentiation because of breed differences was 0.100, with a range of 0.036-0.263. No significant correlation was found between this parameter and the number of alleles per locus. An increase in the number of homozygous loci with increasing inbreeding could not be shown for the Franches-Montagnes horses. The proportion of shared alleles, combined with the neighbour-joining method, defined clusters for Icelandic Horse, Comtois, Arabians and Franches-Montagnes. A more disparate clustering could be seen for European Warmbloods and Thoroughbreds, presumably from frequent grading-up of Warmbloods with Thoroughbreds. Grading-up effects were also observed when Bayesian and Monte Carlo resampling approaches were used for individual assignment to a given population. Individual breed assignments to defined reference populations will be very difficult when introgression has occurred. The Bayesian approach within the Franches-Montagnes breed differentiated individuals with varied proportions of Warmblood.

The chemokine CCL20 and its receptor CCR6 in human malignancy with focus on colorectal cancer

Chemokines are a superfamily of small chemotactic cytokines, which interact with their G-protein-coupled receptors. These interactions regulate multiple physiological functions, particularly tissue architecture and compartment-specific migration of white blood cells. It has been found that the chemokine/chemokine receptor system has been utilized by cancer cells for migration and metastasis. The chemokine receptor CCR6 is expressed in colorectal cancer and several other cancer types, and stimulation by its physiological chemokine ligand CCL20 has been reported to promote cancer cell proliferation and migration in vitro. Moreover, CCR6/CCL20 interactions apparently play a role in organ selective liver metastasis of colorectal cancer. Here, we review the literature on expression patterns of CCL20 and CCR6 and their physiological interactions as well as the currently presumed role of CCR6 and CCL20 in the formation of colorectal cancer liver metastasis, providing a potential basis for novel treatment strategies.

Effects of nasal calcitonin on bone mineral density following parathyroidectomy in patients with primary hyperparathyroidism

Apatani phonology and lexicon, with a special focus on tone

Despite being one of the most extensively researched of Eastern Himalayan languages, the basic morphological and phonological-prosodic properties of Apatani (Tibeto-Burman > Tani > Western) have not yet been adequately described. This article attempts such a description, focusing especially on interactions between segmental-syllabic phonology and tone in Apatani. We highlight three features in particular – vowel length, nasality and a glottal stop – which contribute to contrastively-weighted syllables in Apatani, which are consistently under-represented in previous descriptions of Apatani, and in absence of which tone in Apatani cannot be effectively analysed. We conclude that Apatani has two “underlying”, lexically-specified tone categories H and L, whose interaction with word structure and syllable weight produce a maximum of three “surface” pitch contours – level, falling and rising – on disyllabic phonological words. Two appendices provide a set of diagnostic procedures for the discovery and description of Apatani tone categories, as well as an Apatani lexicon of approximately one thousand entries.

The effect of desmopressin on platelet function: a selective enhancement of procoagulant COAT platelets in patients with primary platelet function defects.

1-deamino-8-d-arginine vasopressin (desmopressin [DDAVP]) is clinically efficacious in patients with mild platelet function disorders but it is not known which mechanisms mediate this effect. Our aim was to evaluate the impact of in vivo DDAVP administration in these patients. We assessed von Willebrand factor (VWF), factor VIII, platelet activation and aggregation, platelet-dependent thrombin generation, and platelet intracellular Na(+)/Ca(2+) fluxes, before and 2 and 4 hours after DDAVP (0.3 µg/kg). We found (1) no significant changes for P-selectin expression, PAC-1 binding, δ-granule content and secretion, and platelet-aggregation; (2) significant decreases of secretion of α-granules and GPIIb-IIIa activation induced by adenosine 5'-diphosphate, convulxin, and thrombin; (3) significant increases of procoagulant platelets induced by convulxin/thrombin and platelet-dependent thrombin generation; and (4) significant increases of intracellular Na(+)/Ca(2+) concentrations. We show that in vivo DDAVP selectively and markedly enhances the ability to form procoagulant platelets and increases platelet-dependent thrombin generation by enhancing Na(+)/Ca(2+) mobilization. This report indicates that the beneficial hemostatic effect of DDAVP is not limited to an increase in large VWF multimers. An enhancement of platelet procoagulant activity appears to be an additional and (at least in platelet disorders) -possibly clinically relevant mechanism of DDAVP's action.

Evaluation of the March of Dimes Family Support Program with Focus on Parent to Parent Support

The March of Dimes NICU Family Support Program provides families with support specialists, educational materials, and community resources to aide in the emotional and physical adaptation to a new life with a premature infant. Parent-to-parent support has been shown to more effective than group support because the new NICU parent is able to connect on a more personal level with an experienced NICU parent. The purpose of the research was to develop and implement an evaluation instrument to assess the effectiveness of the March of Dimes NICU Family Support Program (MODFSP) in the NICU at the UConn Health Center, specifically parent-to-parent support. Steps involved in the process included determining areas of focus for the instrument, developing items based on MODFSP materials and literature review, piloting the materials on parents with infants in the NICU (with IRB approval), and utilizing descriptive statistics through SPSS Version 14 to assess the results from the instrument content. Qualitative items were also included in the evaluation, and descriptive qualitative methods, as appropriate, were used to analyze those items. The findings have supported the literature in that all parents that participated in parent to parent support agreed the program was beneficial in assisting them with their transition to life with a premature infant. In addition to evaluating the new NICU parent’s opinions of the program, researchers evaluated the staff and volunteer parents that were involved in the program. The results also revealed that the new NICU parent’s fear, anxiety, and stress decreased after the parent-to-parent interactions. The preliminary results were encouraging that the MODFSP has implemented an effective parent-to-parent support program to support parents through their time of crisis.

The water footprint of a river basin with a special focus on groundwater: The case of Guadalquivir basin (Spain).

In addition to revealing the hidden link between products or consumption patterns of populations and their needs in terms of water resources, the water footprint (WF) indicator generates new debates and solutions on water management at basin scale. This paper analyses the green and blue WF of the Guadalquivir basin and its integration with environmental water consumption, with a special emphasis on the WF from groundwater and its consequences on current and future depletion of surface water. In a normal year, green WF (agriculture and pastures) amounts to 190 mm on a total green water consumption of 410 mm, while the blue WF (50 mm) represents half of the total blue water flows. This constitutes a first overview and alternative interpretations of the WF as human water appropriation are introduced. The blue WF is almost entirely associated to agriculture (40 mm). The presentation of its evolution over the period 1997?2008 reveals the rising WF from groundwater (13 mm in 2008), 86% being current consumption of surface flows. This evolution is particularly ascribed to the recent development of irrigated olive groves from groundwater. To prevent a higher pressure on the environment, this new use, like all others (thermo-solar plants, tourism, etc.), could have been obtained from the reallocation of water from crops with low water productivity. It means that water is not lacking in the Guadalquivir basin if the governance setting integrates more flexibility and equity in the allocation of water to address climatic variability and the emergence of new demands.
