Efectos de un programa de ejercicios respiratorios sobre la función pulmonar y la tolerancia al ejercicio físico en un grupo de pacientes con Lupus Eritematoso Sistémico

El Lupus eritematoso sistémico (LES) es una enfermedad autoinmune compleja que puede aparecer a cualquier edad, aunque afecta fundamentalmente a mujeres jóvenes en edad fértil. Su cuadro clínico es heterogéneo, pudiendo afectar a casi cualquier órgano. Este estudio piloto tiene como finalidad investigar los efectos de la realización de un programa adaptado de ejercicios respiratorios sobre, principalmente, la función pulmonar y la tolerancia al ejercicio, en un grupo de pacientes con LES. Para cuantificar dichos efectos, usaremos el dispositivo Spirodoc+oxi para realizar espirometrías, pulsioximetrías nocturnas y test de los seis minutos marcha, así como un cuestionario de calidad de vida relacionada con la salud y un cuestionario de somnolencia diurna. Dichas pruebas se realizarán antes y después de la intervención, cuya duración será de 12 semanas. Una vez finalizada la intervención, se procederá al análisis y comparación de los parámetros obtenidos durante las mediciones pre y post-intervención, para así concluir si existen o no efectos y en qué consisten en caso de que los hubiera. El objeto del estudio está motivado por la falta de contenidos enfocados al tratamiento fisioterapéutico del paciente con LES y la necesidad de encontrar vías no farmacológicas para controlar los síntomas derivados de una enfermedad sistémica y de carácter crónico.Systemic Lupus Erythematosus (SLE) is a complex autoimmune disease that can occur at any age but mainly affects young women on childbearing age. Its clinical profile is heterogeneous and almost every organ can be damaged. This pilot study aims to investigate the effects of the implementation of an adapted program of respiratory exercises on, mainly, the pulmonary function and the exercise tolerance, in a group of patients with SLE. In order to quantify these effects, we use the Spirodoc+oxy device to perform a spirometry, a nocturnal pulseoximetry, and a six minute-walk test. Moreover, patients will be given a health-related quality of life questionnaire and a daytime sleepiness test.These tests will be performed before and after the intervention, which will last for 12 weeks. Once the intervention concludes, we will proceed to make the analysis and comparison of the parameters obtained during the pre and the post-intervention measurement in order to conclude whether there are effects or not and which are they if there is any. The aim of the study is motivated by the lack of contents focused on physiotherapy treatment on patients with SLE and the need of finding non-pharmacological ways to control the symptoms caused by a systemic and chronic character disease

Use of portable devices and confocal Raman spectrometers at different wavelength to obtain the spectral information of the main organic components in tomatoes (Solanum Lycopersicum) fruits

Tomato (Solanum lycopersicum) fruit samples, in two ripening stages, ripe (red) and unripe (green), collected from a cultivar in the North of Spain (Barrika, Basque Country), were analyzed directly, without any sample pretreatment, with two different Raman instruments (portable spectrometer coupled to a micro-videocamera and a confocal Raman microscope), using two different laser excitation wavelengths (514 and 785 nm, only for the confocal microscope). The combined use of these laser excitation wavelengths allows obtaining, in a short period of time, the maximum spectral information about the main organic compounds present in this fruit. The major identified components of unripe tomatoes were cutin and cuticular waxes. On the other hand, the main components on ripe tomatoes were carotenes, polyphenoles and polysaccharides. Among the carotenes, it was possible to distinguish the presence of lycopene from b-carotene with the help of both excitation wavelengths, but specially using the 514 nm one, which revealed specific overtones and combination tones of this type of carotene.This work has been financially supported by Research Project S-PE11-UN128 of the Basque Country government.

A note on local bases and convergence in fuzzy metric spaces

In the context of fuzzy metrics in the sense of George and Veeramani, we study when certain families of open balls centered at a point are local bases at this point. This question is related to p-convergence and s-convergence. © 2013 Elsevier B.V.

Diagenetic processes in a partially dolomitized carbonate reservoir: Casablanca oil field, Mediterranean Sea, offshore Spain

Mesozoic and Neogene carbonates located in the Valencia Trough (offshore Spain, western Mediterranean Sea) are oil reservoirs. This paper investigates the diagenetic evolution of the Upper Jurassic limestones, currently dolomitized, that constitute the main reservoir of the Casablanca oil field. Core samples from Casablanca-1A well have been studied to determine the diagenetic products and their relation with porosity evolution, and to reconstruct the fluid flow history prior to and during oil emplacement. On the basis of petrological observations and geochemical analyses (major, minor and trace element composition and oxygen, carbon and strontium isotope composition), a major dolomitization event is recognized postdating subaerial exposure, erosion and karstification. The dolomitization event originated two replacive dolomites (RD1 and RD2) and two dolomite cements (saddle dolomite cement, SDC, and milky-white dolomite cement, MDC) which are partially cogenetic. RD1, RD2 and SDC precipitated at increasing temperatures (over 60ºC and below 110ºC), probably from meteoric water mixed with marine water. The last dolomite type (milky-white dolomite cement) precipitated with increasing burial conditions and by arrival of hydrothermal fluids during the Miocene. The post-dolomitization sequence comprises precipitation of calcite cement and partial calcitization of all previous dolomites. The oxygen, carbon and strontium isotope compositions suggest that this calcite cementation occurred from meteoric waters mixed with Burdigalian - Langhian marine waters trapped in the sediments and expelled by compaction in the moderate to deep burial realm. Normal faults were the conduits for upward migration of these fluids as well as for later oil expulsion from the Burdigalian - Langhian source rocks. Late corrosion associated with organic acid-enriched fluids took place prior or simultaneously to oil migration during the Pliocene, enhancing porosity and increasing reservoir quality

On-site forest fire smoke detection by low-power autonomous vision sensor

Early detection plays a crucial role to prevent forest fires from spreading. Wireless vision sensor networks deployed throughout high-risk areas can perform fine-grained surveillance and thereby very early detection and precise location of forest fires. One of the fundamental requirements that need to be met at the network nodes is reliable low-power on-site image processing. It greatly simplifies the communication infrastructure of the network as only alarm signals instead of complete images are transmitted, anticipating thus a very competitive cost. As a first approximation to fulfill such a requirement, this paper reports the results achieved from field tests carried out in collaboration with the Andalusian Fire-Fighting Service (INFOCA). Two controlled burns of forest debris were realized (www.youtube.com/user/vmoteProject). Smoke was successfully detected on-site by the EyeRISTM v1.2, a general-purpose autonomous vision system, built by AnaFocus Ltd., in which a vision algorithm was programmed. No false alarm was triggered despite the significant motion other than smoke present in the scene. Finally, as a further step, we describe the preliminary laboratory results obtained from a prototype vision chip which implements, at very low energy cost, some image processing primitives oriented to environmental monitoring.Ministerio de Ciencia e Innovación 2006-TIC-2352, TEC2009-1181

CMOS Architectures and circuits for high-speed decision-making from image flows

We present architectures, CMOS circuits and CMOS chips to process image flows at very high speed. This is achieved by exploiting bio-inspiration and performing processing tasks in parallel manner and concurrently with image acquisition. A vision system is presented which makes decisions within sub-msec range. This is very well suited for defense and security applications requiring segmentation and tracking of rapidly moving objects

std-Convergence in fuzzy metric spaces

In this note we answer two recent questions posed by Morillas and Sapena [10] related to standard convergence in fuzzy metric spaces in the sense of George and Veeramani. The obtained results lead us to establish what conditions must satisfy a concept about sequential convergence to be considered compatible with a concept of Cauchyness.Juan Jose Minana acknowledges the support of Conselleria de Educacion, Formacion y Empleo (Programa Vali+d para investigadores en formacion) of Generalitat Valenciana, Spain, ACIF/2012/040, and the support of Universitat Politecnica de Valencia under Grant PAID-06-12 SP20120471.Gregori Gregori, V.; Miñana, JJ.

Deliberate donation of umbilical cord blood in the University Hospital Virgen de la Arrixaca (2010-2011). Current situation and influences of the obstetrical-foetal variables

Objetivos: A principios de 2010 el Hospital Universitario Virgen de la Arrixaca puso en marcha, en el servicio de partos, el protocolo de donación voluntaria de sangre de cordón umbilical (SCU). Desde la reflexión y la autoevaluación, planteamos un análisis de nuestra situación actual a través del estudio de la influencia de las variables obstétrico-fetales en la calidad de las muestras. Métodos: Con este fin hemos planteado un trabajo de tipo observacional, descriptivo, retrospectivo y de corte transversal desde mayo de 2010 a noviembre de 2011, con el objetivo de aumentar la calidad de las unidades de SCU y optar por una gestión eficiente que haga sostenible el proyecto. Resultados: Se obtuvieron 123 donaciones potenciales de sangre de cordón y del análisis multivariable de las mismas obtuvimos una correlación positiva significativa entre el número de leucocitos, las semanas de gestación y el parto vaginal. El peso inicial de la unidad se incrementó significativamente a mayor peso del recién nacido y paridad de la donante. Conclusiones: Como conclusiones del estudio nos planteamos esbozar posibles factores predictivos que permitan seleccionar las muestras de mayor calidad y sean complemento de los actuales estándares elaborados por el Banco Público de Málaga. En este sentido nuestros resultados sugieren que en los partos con más semanas de gestación, paridad de la gestante y peso del recién nacido, así como en los partos vaginales, encontramos mayores posibilidades de obtener muestras de alta calidad.Aims: At the beginning of 2010, the University Hospital la Arrixaca, set up the protocol, in the birth delivery service, of umbilical cord blood (U.C.B.) donation. From the reflexion and the self-evaluation, we set out an analysis of our current situation through the study of the influences of the obstetricalfoetal variables in the samples quality. Method: On this purpose, we set out an observational descriptive, retrospective and cross-section study from May 2010 to November 2011, so as to increase the quality of the UCB units and to opt for efficient management that would make the project sustainable. Results: We obtained 123 potential donations of umbilical cord blood and out of the multivariable analysis we obtained a positive and significant correlation between the number of leukocytes, the weeks of pregnancy and the vaginal birth. The initial weight of the unit significantly increased to a heavier weight of the new born and the amount of times a donor has given birth. Conclusions: As conclusions from this study we suggest to outline possible predictive factors that would allow us to select the best quality samples and would be a complement to the current standards produced by the Public Bank of Malaga. In this sense our results suggest that in the deliveries with more weeks of pregnancy, in the amount of times a woman has given birth and in the weight of the new born as well as in the vaginal deliveries we can find more possibilities of obtaining high quality samples
