Parvipalpus onubensis, a new species (Crustacea: Amphipoda: Caprellidea) from the Atlantic coast of Southern Spain*
Parvipalpus onubensis n. sp. is described based on the specimens collected from sediments on the coast of Huelva (Southwest Spain). The new species is compared with the other species in the genus:Parvipalpus capillaceus (Chevreux, 1887), P. linea Mayer, 1890 and P. major Carausu, 1941. Parvipalpus onubensis differs from the remaining species of Parvipalpus by the simultaneous combination of the following characters: small size (body length up to 2.8 mm), rostrum present, body completely smooth, flagellum of antenna 1 with 5 articles in males and 3 in females, mandibular palp 2-articulate, incisor and lacinia mobilis 4-toothed and penes well developed
A novel ensemble method for electric vehicle power consumption forecasting: Application to the Spanish system
The use of electric vehicle across the world has become one of the most challenging issues for environmental policies. The galloping climate change and the expected running out of fossil fuels turns the use of such non-polluting cars into a priority for most developed countries. However, such a use has led to major concerns to power companies, since they must adapt their generation to a new scenario, in which electric vehicles will dramatically modify the curve of generation. In this paper, a novel approach based on ensemble learning is proposed. In particular, ARIMA, GARCH and PSF algorithms' performances are used to forecast the electric vehicle power consumption in Spain. It is worth noting that the studied time series of consumption is non-stationary and adds difficulties to the forecasting process. Thus, an ensemble is proposed by dynamically weighting all algorithms over time. The proposal presented has been implemented for a real case, in particular, at the Spanish Control Centre for the Electric Vehicle. The performance of the approach is assessed by means of WAPE, showing robust and promising results for this research field.Ministerio de Economía y Competitividad Proyectos ENE2016-77650-R, PCIN-2015-04 y TIN2017-88209-C2-R

2023 GEIS Guidelines for gastrointestinal stromal tumors
Avapritinib; Gastrointestinal stromal tumor; SurgeryAvapritinib; Tumor estromal gastrointestinal; CirurgiaAvapritinib; Tumor estromal gastrointestinal; CirugíaGastrointestinal stromal tumor (GIST) is the most common malignant neoplasm of mesenchymal origin. GIST spans a wide clinical spectrum that ranges from tumors with essentially no metastatic potential to malignant and life-threatening spread diseases. Gain-of-function mutations in KIT or PDGFRA receptor tyrosine kinases are the crucial drivers of most GISTs, responsible for tumor initiation and evolution throughout the entire course of the disease. The introduction of tyrosine kinase inhibitors targeting these receptors has substantially improved the outcomes in this formerly chemoresistant cancer. As of today, five agents hold regulatory approval for the treatment of GIST: imatinib, sunitinib, regorafenib, ripretinib, and avapritinib. This, in turn, represents a success for a rare neoplasm. During the past two decades, GIST has become a paradigmatic model in cancer for multidisciplinary work, given the disease-specific particularities regarding tumor biology and tumor evolution. Herein, we review currently available evidence for the management of GIST. This clinical practice guideline has been developed by a multidisciplinary expert panel (oncologist, pathologist, surgeon, molecular biologist, radiologist, and representative of patients’ advocacy groups) from the Spanish Group for Sarcoma Research, and it is conceived to provide, from a critical perspective, the standard approach for diagnosis, treatment, and follow-up.This work was supported in part by AECC (CLSEN20004SERR) and the Fero Foundation, both to CS
Differences in scapular upward rotation, pectoralis minor and levator scapulae muscle length between the symptomatic, the contralateral asymptomatic shoulder and control subjects: a cross-sectional study in a Spanish primary care setting
Objective To determine the potential differences in both
scapular positioning and scapular movement between the
symptomatic and asymptomatic contralateral shoulder, in
patients with unilateral subacromial pain syndrome (SAPS),
and when compared with participants free of shoulder
pain.
Setting Three different primary care centres.
Participants A sample of 73 patients with SAPS in their
dominant arm was recruited, with a final sample size of 54
participants.
Primary outcome measures The scapular upward
rotation (SUR), the pectoralis minor and the levator
scapulae muscles length tests were carried out.
Results When symptomatic shoulders and controls
were compared, an increased SUR at all positions (45°,
90° and 135°) was obtained in symptomatic shoulders
(2/3,98/8,96°, respectively). These differences in SUR
surpassed the minimal detectable change (MDC95)
(0,91/1,55/2,83° at 45/90/135° of shoulder elevation).
No differences were found in SUR between symptomatic
and contralateral shoulders. No differences were found in
either pectoralis minor or levator scapulae muscle length
in all groups.
Conclusions SUR was greater in patients with chronic
SAPS compared with controls at different angles of
shoulder elevation
Interoperabilidad en Sistemas Domóticos Mediante Pasarela Infrarrojos-ZigBee
La domótica consiste en la aplicación de técnicas provenientes de la automática industrial al hogar con objeto de ofrecer servicios que aporten, entre otras cosas, confort, seguridad y eficiencia energética a los usuarios. Hasta el momento la penetración de dichas técnicas en los hogares ha sido reducida. Una de las razones fundamentales de esta lenta transposición de técnicas de control al hogar es la dificultad de integración entre los diferentes sistemas presentes en el hogar. En este artículo se presenta un desarrollo encaminado a mejorar la integración de los sistemas domóticos con aquellos dispositivos que sean controlables mediante infrarrojos. En concreto se ha desarrollado una pasarela inalámbrica que permite a una red domótica el envío de tramas de infrarrojos. De esta manera se posibilita un despliegue rápido y económico de los nodos que sean necesarios para integrar dispositivos tales como los sistemas de aire acondicionado en una red domótica.Ministerio de Industria, Turismo y Comercio MITC-09-TSI-020100-2009-359Ministerio de Educación DPI2008-05818Junta de Andalucía TEP0272
Comparison of Different Bone Filling Materials and Resorbable Membranes by Means of Micro-Tomography. A Preliminary Study in Rabbits
The purpose of this work was to evaluate the behavior of different membranes and bone filling materials used to fill critical defects in rabbit calvaria. Four defects were prepared in the cranial calvaria of female rabbits. They were randomly divided into three subgroups according to the type of barrier membrane to be used. Four animals carried cross-linked bovine collagen membranes (Mem-Lok, Bio-Horizons, Birmingham, AL, USA)), four human fascia lata membranes (Tissue, Inbiomed SA, Córdoba, Argentina) and four human chorioamniotic membranes (Tissue. Inbiomed SA, Córdoba, Argentina). The defects were filled with the deproteinized bovine bone particulate BioOss®(GeistlichPharma AG, Wolhusen, Switzerland), with particulate human hydroxyapatite MinerOss®(Bio-Horizons, Birmingham, AL, USA), with particulate dental material (Tissue Bank Foundation, Inbiomed S.A., Córdoba, Argentina), and the last one was left without the addition of filler material. In the first group of four specimens, a resorbable cross-linked bovine collagen membrane was placed over the skull and defects, without additional fixing. In the second group, a human fascia lata membrane was placed, without additional fixing. In the third group,
a human chorioamniotic membrane was placed, without additional fixing. The animals were sacrificed at 4 and 8 weeks. The highest percentages of relative radiological density (average) were recorded considering the amnio-chorionic membranes (83.63%) followed by collagen (81.44%) and finally the fascia lata membranes (80.63%), but the differences were not statistically significant (p > 0.05). The sites grafted with a decellularized tooth (96.83%) and BioOss (88.42%), recorded the highest percentages of radiological density but did not differ significantly from each other (subset 2). The three membranes used did not show statistical differences between them, in any of the two time periods used. There were statistical differences between the filling materials evidencing the presence of a large quantity of calcified material in the defects treated with particulate tooth and deproteinized bovine bone and while smaller amounts of calcified material were registered in the case of defects treated with human hydroxyapatite and those that were not treated.publishedVersionFil: Fernández Bodereau, Enrique.

ESTRO IORT Task Force/ACROP recommendations for intraoperative radiation therapy in borderline-resected pancreatic cancer
Radiation therapy (RT) is a valuable component of multimodal treatment for localized pancreatic cancer.
Intraoperative radiation therapy (IORT) is a very precise RT modality to intensify the irradiation effect for
cancer involving upper abdominal structures and organs, generally delivered with electrons (IOERT).
Unresectable, borderline and resectable disease categories benefit from dose-escalated chemoradiation
strategies in the context of active systemic therapy and potential radical surgery. Prolonged preoperative
treatment may act as a filter for selecting patients with occult resistant metastatic disease. Encouraging
survival rates have been documented in patients treated with preoperative chemoradiation followed by
radical surgery and IOERT (>20 months median survival, >35% survival at 3 years). Intensive preoperative
treatment, including induction chemotherapy followed by chemoradiation and an IOERT boost, appears
to prolong long-term survival within the subset of patients who remain relapse-free for>2 years
(>30 months median survival; >40% survival at 3 years). Improvement of local control through higher
RT doses has an impact on the survival of patients with a lower tendency towards disease spread.
IOERT is a well-accepted approach in the clinical scenario (maturity and reproducibility of results), and
extremely accurate in terms of dose-deposition characteristics and normal tissue sparing. The technique
can be adapted to systemic therapy and surgical progress. International guidelines (National
Comprehensive Cancer Network or NCCN guidelines) currently recommend use of IOERT in cases of close
surgical margins and residual disease. We hereby report the ESTRO/ACROP recommendations for performing IOERT in borderline-resectable pancreatic cancer
Metodología cartográfica submarina orientada a la gestión y conservación del medio litoral: mapa de las comunidades bentónicas del frente litoral norte del estrecho de Gibraltar
La cartografía de las comunidades bentónicas es esencial, actualmente, para promover actuaciones eficientes de uso, gestión y conservación de las zonas litorales, especialmente en el ámbito de grandes espacios litorales protegidos. En cada uno de éstos, la cartografía resulta determinante para la elaboración de un mapa de zonificación de usos, condicionado, en gran medida, por los distintos valores ecológicos que puedan asignarse a las diferentes comunidades bentónicas establecidas y a sus distribuciones geográficas locales. La metodología utilizada en la elaboración del mapa de las comunidades bentónicas del estrecho de Gibraltar (en el intervalo batimétrico 0-30 m y de 40 km de extensión litoral aproximada), dada la complejidad que reviste este tipo de objetivos, supone una aproximación a la cartografía de la biota sésil sumergida, en tramos litorales amplios contenidos en áreas protegidas. Se han combinado, mediante superposición de información, datos físicos de batimetría y tipos de fondo, obtenidos mediante técnicas acústicas y convenientemente cartografiados, con datos biológicos de las comunidades bentónicas, obtenidos en campaña intensiva de buceo científico (con la toma de imágenes en sustrato duro, para su ulterior análisis) y mediante dragado (con registros de granulometría y fauna endobentónica en sustrato blando). La información ha sido georreferenciada adecuadamente para su introducción, como capas independientes, en un sistema de información geográfica (SIG).The cartography of benthic communities is, today, essential to promoting adequate strategies for the use, management and conservation of littoral areas, especially if they are large protected zones. In each zone, cartography is necessary to elaborate a management zoning map, depending on the ecological value of the different benthic communities established and on the local geographical distribution. The methodology used in the elaboration of a map including the benthic communities of the Straits of Gibraltar (0-30 m depth; 40 km of littoral extension), in spite of the complexity of these kinds of objectives, represents an approach to the cartography of the submarine sessile biota of large littoral zones of protected ar- eas. The present study combines physical data (bathymetry and type of substrate), collected using acoustic techniques, and biological data (benthic communities), collected during an intensive sampling programme using scuba (hard bottom: image analysis) and dredging (soft bottom: granulometry and benthic fauna). The information has been geoindexed to be inserted, as different layers, into a Geographic Information System (GIS)
