[EN] Different families of Runge-Kutta-Nyström (RKN) symplectic splitting methods of order 8 are presented for second-order systems of ordinary differential equations and are tested on numerical examples. They show a better efficiency than state-of-the-art symmetric compositions of 2nd-order symmetric schemes and RKN splitting methods of orders 4 and 6 for medium to high accuracy. For some particular examples, they are even more efficient than extrapolation methods for high accuracies and integrations over relatively short time intervals., This work has been supported by Ministerio de Ciencia e Innovacion (Spain) through project PID2019-104927GB- C21, MCIN/AEI/10.13039/501100011033.

La valeur en sante, consistant a produire de meilleurs resultats tout en maitrisant les couts, necessite d’etablir des mesures normees des resultats, prenant en compte ce qui importe aux patients. Le but etait de construire ce type de questionnaire pour le parcours de soins des patients atteint d’un cancer du pancreas. Methodologie Un groupe de travail multidisciplinaire (GTM), associant des patients a fait une revue systematique des resultats utilises dans les essais cliniques a partir de clinicaltrials.gov., et a selectionne les plus pertinents. Un comite international multidisciplinaire associant des patients a valide par methode Delphi le questionnaire. Resultats 570 etudes cliniques ont ete selectionnees et 3370 parametres ont ete repertories (cliniques = CROM, et de qualite de vie = PROM). De janvier 2018 a juin 2018, parmi ces parametres, le GTM a propose une liste de 102 parametres (92 CROM et 10 PROM) au comite international. Un ensemble de 78 variables a ete retenu apres les 4 etapes du vote Delphi pour constituer le questionnaire final incluant des PROM par l’utilisation de « Fact-Hep ». Conclusions Pour la premiere fois, un questionnaire standardise concernant le cancer du pancreas, axes sur le patient, a ete mis etabli, permettant desormais son deploiement.

The aim of commercial pig breeding programs is to maximize the number of pigs produced per sow per year. Given that sows exhibit an estrus during lactation is a potential means of increasing productivity of a pig breeding herd without reducing in lactation length, conventionally, weaning of piglets at a relatively young age is often related to post-weaning piglet performance which compromises piglet welfare. Therefore, intermittent suckling (IS) is a management technique in which lactating sows are separated from their piglets for a fixed period of the days and allowing sows to continue nursing piglets while exhibiting estrus and being breed during lactation, thereby promoting both piglet well-being and sow reproductive performance [1]. For this study, primiparous sows (PP) were exposed to 28day (D28) lactation with intermittent suckling (IS) during the final week prior to weaning. The sows detected to be in estrus during lactation were either bred at this first estrus (FE) during lactation (IS21FE), or were “skipped” and bred at their second estrus which occurred after final weaning at D28 (IS21SE). Despite the benefits of IS, the effects of the maternal physiology related to breeding during lactation on embryonic transcriptome are largely unknown. Recent advances in the ability to assess embryonic gene expression in both sexes have made these analyses possible. Here, we describe the experimental procedures of two color microarray analyses and annotation of differentially expressed (DE) genes in detail corresponding to data deposited at NCBI in the Gene Expression Omnibus under accession number GSE53576 and GSE73020 for day 9 embryos (D9E) and day 30 embryos (D30E) respectively. Although only a few DE genes were discovered between IS21FE and IS21SE in both sexes from D9E or D30E, the raw data are still valuable for future use to understand the gene expression profiling from two different developmental stages.

Resumen: Introducción: A pesar del creciente interés por las funciones de la vitamina D, siguen documentándose casos deficitarios en regiones soleadas donde se presuponen niveles adecuados. El objetivo del estudio es determinar los niveles de 25-hidroxivitamina D en menores de 2 años ingresados en un hospital terciario de Valencia por enfermedades agudas leves y su relación con factores que puedan estar asociados con su deficiencia. Métodos: Estudio prospectivo y descriptivo de un año de duración en niños, entre uno y 24 meses, ingresados por enfermedades agudas leves. Se han estudiado los niveles de 25-hidroxivitamina D, junto con una anamnesis y exploración clínica estructuradas. Se dividió la muestra en 2 grupos, dependiendo de los niveles de vitamina D (punto de corte 30 ng/ml). Resultados: Se estudiaron 169 niños, edad media de 9 meses, predominio etnia caucásica (75,7%) y menores de un año (79,3%). El 24,3% de los niños presentaba valores 30 ng/ml fueron: administración de profilaxis, ser hijo de madre caucásica y que no usara hiyab. No existieron diferencias en el tipo de lactancia recibida (p = 0,65). Solamente al 47% de los menores de un año amamantados se administró profilaxis. Conclusiones: En Valencia, a pesar de la radiación solar suficiente, un cuarto de los niños 30 ng/mL were associated with vitamin D prophylaxis during the first year, in children of a Caucasian mother, and those who did not wear a hijab. No statistical differences were found in diet characteristics (P = .65). Prophylaxis was given to 47% of the breastfed children younger than one year. Conclusions: In Valencia, Spain, 25-hydroxivitamin D levels lower than 30 ng/mL were found in a quarter of the children younger than two years. Our results emphasize the importance of vitamin D prophylaxis during the first year of life, even in sunny Mediterranean regions.

Introduction: Despite the increasing interest in vitamin D functions, new cases of deficiency have been reported in sunny regions where optimal levels are expected. The aim of this study was to analyze 25-hydroxivitamin D levels in children younger than 2 years admitted for acute mild diseases in a tertiary hospital in Valencia and its relationship with factors that can be associated with its deficiency. Methods: This one year prospective and observational study was conducted on 169 children admitted for acute mild diseases. 25-Hydroxivitamin D levels were analyzed. A standardized physical examination and structured interviews to the parents were performed. Children were classified into two groups, according to 25-hydroxivitamin D levels (cut-off 30 ng/mL). Results: A total of 169 children were included, with a median age of 9 months, being more prevalent Caucasians (75.7%) and younger than one year old (79.3%). Almost one quarter (24.3%) of the children had 25-hydroxivitamin D levels 30 ng/mL were associated with vitamin D prophylaxis during the first year, in children of a Caucasian mother, and those who did not wear a hijab. No statistical differences were found in diet characteristics (P = .65). Prophylaxis was given to 47% of the breastfed children younger than one year. Conclusions: In Valencia, Spain, 25-hydroxivitamin D levels lower than 30 ng/mL were found in a quarter of the children younger than two years. Our results emphasize the importance of vitamin D prophylaxis during the first year of life, even in sunny Mediterranean regions.

[ES] La Universitat Politècnica de Valencia (UPV) facilita la creación de equipos de innovación y calidad educativa (EICE). Uno de dichos equipos es GRIM4E (GRoup of Innnovative Methodologies and Assessment For Engineering education) que comenzó a realizar innovaciones metodológicas al adaptar las asignaturas de matemáticas a los grados surgidos dentro del proceso de Bolonia. Algunas de dichas innovaciones ya habían sido iniciadas con anterioridad como una evaluación continua de todas las actividades de aprendizaje desarrolladas durante el curso, con más de 30 actos de evaluación en la actualidad en las asignaturas anuales y 10 en las semestrales. Otras fueron pioneras como el empleo sistemático de la clase inversa en las prácticas informáticas de las asignaturas involucradas. Una innovación reciente destacada en nuestro ámbito ha sido el fomento de una actitud activa y colaborativa de los alumnos en la preparación de los actos de evaluación más relevantes. En este trabajo presentamos estas líneas desarrolladas por GRIM4E e incluimos resultados de encuestas anónimas realizadas para recabar la percepción de los alumnos sobre la metodología mixta empleada.

Summary Objective Reducing the time required for diagnosis is one of the major challenges to improving and accelerating the management of patients. The aim of this work is to describe an organizational innovation in the management of patients with hepatobiliary or pancreatic diseases, and to report the initial results. Materials and methods A multidisciplinary and multi-professional working group designed and instituted a patient-centered organizational system that optimizes the investigation of liver and pancreatic diseases, in order to achieve diagnosis in one day. From January 2017 to June 2017, all patients referred for consultation for hepatobiliary or pancreatic pathology were included in this new management pathway. Data were collected prospectively in a standardized form. Results Fifty-six patients with hepatobiliary or pancreatic disease were evaluated in the program during dedicated slots over a total of 20 days. Of these, four patients underwent evaluation in the program twice. The average number of patient slots in the program was three per day (range: 1–5). An additional computed tomography (CT) and/or magnetic resonance imaging (MRI) was required in 23 (41.7%) of the visits. These imaging studies were performed the same day, including nine patients who required both types of imaging (16.7% of cases). “One-day diagnosis” established an accurate diagnosis by the end of the day in 49 patient encounters (81.7%). Overall assessment of this organization was considered excellent by 46 (83%) of patients. Conclusion An organizational innovation has made it possible to effectively diagnose hepatobiliary or pancreatic pathology within one day in the majority of cases, with good patient satisfaction. It is now necessary to evaluate the medico-economic aspect of this organization, and more generally to develop a methodology for multidimensional evaluation of organizational innovations.

Research into prenatal programming in the pig has shown that the sex of the developing embryo or fetus can influence the developmental outcome. Therefore, the ability to determine an embryo's sex is necessary in many experiments particularly regarding early development. The present protocol demonstrates an inexpensive, rapid and non-toxic preparation of pig genomic DNA for use with PCR. Day 30 embryos must be humanely collected according to the guidelines established by Institutional Animal Policy and Welfare Committees for the present protocol. The preparation of the whole embryo for this PCR based sexing technique simply involves grinding the frozen embryo to a fine powder using a pre-chilled mortar and pestle. PCR-quality DNA is released from a small amount of embryo powder by applying a hot incubation in an alkaline lysis reagent. Next, the DNA solution is mixed with neutralization buffer and used directly for PCR. Two primer pairs are generated to detect specific sex determining region of the Y- chromosome (SRY) and ZFX region of the X- chromosome with high accuracy and specificity. The same protocol can be applied to other elongated embryos (Day 10 to Day 14) earlier than Day 30. Also, this protocol can be carried with 96-welled plates when screening a large number of embryos, making it feasible for automation and high-throughput sex typing.

Mathematics background of Engineering students changes drastically between freshmen and sophomore students. This brings out the way in which lab sessions are incorporated must be taken into account as well in the continuous assessment of the subject being a key issue how to incorporate the assessment of lab sessions. At the Higher Technical School of Design Engineering of the Universitat Politecnica of Valencia (UPV) we started using CAS almost 20 years ago and have evolved from the initial lab sessions and their corresponding evaluation. Our learning tells us that the final approach depends on the content of the subject and how relevant are the methods used as well as the capabilities of the CAS used. In addition, the standard use of assignments to reinforce the learning process of each student has also shown to be a keystone to increase the Engineering students competences before each assessment test. Results will be presented concerning a second year Mathematics course in Aerospace Engineering where 100% students attendance was achieved at the end of the third semester, all of them taking all exams, and where we experienced a success rate above 91% which is far of being standard at Spanish Engineering studies.

We consider splitting methods for the numerical integration of non-autonomous sep- arable differential equations. Splitting methods have been extensively used as geometric numerical integrators during the last years showing excellent performances (both qualitatively and quantita- tively) when applied on many problems. They are designed for autonomous separable systems and a substantial number of methods tailored for different structures of the equations have recently ap- peared. When these methods are used on non-autonomous problems, usually their performance diminishes considerably, and even they can lose the order of accuracy. Previous attempts to preserve such performance on non-autonomous problems required to modify, in a non-trivial way, the existing methods. In this paper, we present a simple alternative which, in many relevant cases, allows to retain the high performance of the splitting methods using the same schemes as for the autonomous problems. This technique is applied on different problems and its performance is illustrated on several numerical examples.
