Análisis de los recursos existentes en los centros públicos de infantil y primaria de Castellón para la integración de alumnos con deficiencia motórica
Novenes Jornades de Foment de la Investigació de la FCHS (Any 2003-2004)La inclusión escolar pasa por la integración total de todo el alumnado, es necesaria no sólo la supresión
de barreras arquitectónicas sino la coordinación de toda la comunidad educativa, una formación óptima
del profesorado y especialistas, y la correcta adaptación de los materiales. Presentamos un estudio
realizado en 13 centros públicos de infantil y primaria de Castellón para conocer si poseen los recursos
necesarios para la integración de alumnado con deficiencia motórica. Para ello utilizaremos como
modelo a seguir un Centro Escolar de Integración Preferente de alumnado con deficiencia motórica.
Los resultados generales nos indican la carencia de recursos necesarios para la integración de estas
personas y la presencia de barreras arquitectónicas en la mayoría de los centros
Effects of surface stability on the morphological transformation of metals and metal oxides as investigated by first-principles calculations
Morphology is a key property of materials. Owing to their precise structure and morphology, crystals and nanocrystals provide excellent model systems for joint experimental and theoretical investigations into surface-related properties. Faceted polyhedral crystals and nanocrystals expose well-defined crystallographic planes depending on the synthesis method, which allow for thoughtful investigations into structure-reactivity relationships under practical conditions. This feature article introduces recent work, based on the combined use of experimental findings and first-principles calculations, to provide deeper knowledge of the electronic, structural, and energetic properties controlling the morphology and the transformation mechanisms of different metals and metal oxides: Ag, anatase TiO2, BaZrO3, and α-Ag2WO4. According to the Wulff theorem, the equilibrium shapes of these systems are obtained from the values of their respective surface energies. These investigations are useful to gain further understanding of how to achieve morphological control of complex three-dimensional crystals by tuning the ratio of the surface energy values of the different facets. This strategy allows the prediction of possible morphologies for a crystal and/or nanocrystal by controlling the relative values of surface energies.The authors are grateful to FAPESP (2013/07296-2, 2012/ 14468-1, 2013/26671-9 and 2014/04350-9), CAPES (process A104/2013 and 99999.002998/2014-09), CNPq INCTMN 573636/2008-7, PrometeoII/2014/022 and ACOMP/2014/270 projects (Generalitat Valenciana), Ministerio de Economia y Competitividad (Spain), CTQ2012- 36253-C03-02 and the Spanish Brazilian program (PHB2009-0065-PC) for financially supporting this research.

A 3D platform for the morphology modulation of materials: first principles calculations on the thermodynamic stability and surface structure of metal oxides: Co3O4, α-Fe2O3, and In2O3
Essentially, the exposed crystal planes of a given material, which primarily determine their morphology, tremendously affect its behavior. First principle calculations, based on the Wulff construction model and broken bonding density index, have been performed to calculate the equilibrium and their transformations for different metal oxides: Co3O4, α-Fe2O3, and In2O3. Present results point out that starting by surface thermodynamics is a helpful approach to predict and assess the morphology transformations of these materials. These complete set of morphologies may serve as a guide for researchers, when analyzing the images from electron microscopies, to gain further understanding of how to control crystal shape synthetically by tuning the surface chemistry and by controlling the relative values of surface energies
Diverse Populations of Staphylococcus pseudintermedius Colonize the Skin of Healthy Dogs
Staphylococcus pseudintermedius is a commensal bacterium of the canine skin but is also a key opportunistic pathogen that is responsible for most cases of pyoderma in dogs. The current paradigm indicates that infection arises when predisposing factors alter the healthy skin barrier. Despite their importance, the characteristics of the S. pseudintermedius populations colonizing the skin of healthy dogs are yet largely unknown. Here, we retrieved 67 complete circular genomes and 19 associated plasmids from S. pseudintermedius isolated from the skin of 9 healthy dogs via long-reads Nanopore sequencing. Within the S. pseudintermedius populations isolated from healthy skin, multilocus sequence typing (MLST) detected 10 different STs, distributed mainly by the host. 39% of the 18 representative genomes isolated herein were methicillin-resistant S. pseudintermedius (MRSP), and they showed, on average, a higher number of antibiotic resistance genes and prophages than did the methicillin-sensitive (MSSP). In summary, our results revealed that the S. pseudintermedius populations inhabiting the skin of healthy dogs are relatively diverse and heterogeneous in terms of MLST and methicillin resistance. In this study, all of the 67 commensal S. pseudintermedius populations that were isolated from healthy dogs contained antibiotic resistance genes, indicating the extent and severity of the problem of antimicrobial resistance in staphylococci with zoonotic potential.info:eu-repo/semantics/publishedVersio

Long-term antibiotic therapy in patients with surgery-indicated not undergoing surgery infective endocarditis
Edocarditis infecciosa; Tractament antibiòtic supressiu; CirurgiaEndocarditis infecciosa; Tratamiento antibiótico supresor: CirugíaInfective endocarditis; Suppressive antibiotic treatment; SurgeryBackground:
To date, there is little information regarding management of patients with infective endocarditis (IE) that did not undergo an indicated surgery. Therefore, we aimed to evaluate prognosis of these patients treated with a long-term antibiotic treatment strategy, including oral long term suppressive antibiotic treatment in five referral centres with a multidisciplinary endocarditis team.
Methods:
This retrospective, multicenter study retrieved individual patient-level data from five referral centres in Spain. Among a total of 1797, 32 consecutive patients with IE were examined (median age 72 years; 78% males) who had not undergone an indicated surgery, but received long-term antibiotic treatment (LTAT) and were followed by a multidisciplinary endocarditis team, between 2011 and 2019. Primary outcomes were infection relapse and mortality during follow-up.
Results:
Among 32 patients, 21 had IE associated with prostheses. Of the latter, 8 had an ascending aorta prosthetic graft. In 24 patients, a switch to long-term oral suppressive antibiotic treatment (LOSAT) was considered. The median duration of LOSAT was 277 days. Four patients experienced a relapse during follow-up. One patient died within 60 days, and 12 patients died between 60 days and 3 years. However, only 4 deaths were related to IE.
Conclusions:
The present study results suggest that a LTAT strategy, including LOSAT, might be considered for patients with IE that cannot undergo an indicated surgery. After hospitalization, they should be followed by a multidisciplinary endocarditis team.Antoni Bayes-Genis was supported by grants from the Ministerio de Educación y Ciencia (SAF2014–59892), Fundació La MARATÓ de TV3 (201502, 201516), CIBER Cardiovascular (CB16/11/00403), and AdvanceCat 2014.

Concordance between Antimicrobial Resistance Phenotype and Genotype of Staphylococcus pseudintermedius from Healthy Dogs
Staphylococcus pseudintermedius, a common commensal canine bacterium, is the main cause
of skin infections in dogs and is a potential zoonotic pathogen. The emergence of methicillin-resistant
S. pseudintermedius (MRSP) has compromised the treatment of infections caused by these bacteria.
In this study, we compared the phenotypic results obtained by minimum inhibitory concentration
(MICs) for 67 S. pseudintermedius isolates from the skin of nine healthy dogs versus the genotypic data
obtained with Nanopore sequencing. A total of 17 antibiotic resistance genes (ARGs) were detected
among the isolates. A good correlation between phenotype and genotype was observed for some
antimicrobial classes, such as ciprofloxacin (fluoroquinolone), macrolides, or tetracycline. However,
for oxacillin (beta-lactam) or aminoglycosides the correlation was low. Two antibiotic resistance
genes were located on plasmids integrated in the chromosome, and a third one was in a circular
plasmid. To our knowledge, this is the first study assessing the correlation between phenotype and
genotype regarding antimicrobial resistance of S. pseudintermedius from healthy dogs using Nanopore
sequencing technology.info:eu-repo/semantics/publishedVersio
Novel microgel culture system as semi-solid three-dimensional in vitro model for the study of multiple myeloma proliferation and drug resistance
[EN] Multiple myeloma (MM) is a hematological malignancy in which the patient's drug resistance is one of the main clinical problems. As 2D cultures do not recapitulate the cellular microenvironment, which has a key role in drug resistance, there is an urgent need for better biomimetic models. Here, a novel 3D platform is used to model MM. The semi-solid culture consists of a dynamic suspension of microspheres and MM cells, termed as microgel. Microspheres are synthesized with acrylic polymers of different sizes, compositions, and functionalities (fibronectin or hyaluronic acid). Optimal conditions for the platform in terms of agitation speed and microsphere size have been determined. With these parameters the system allows good proliferation of the MM cell lines RPMI8226, U226, and MM1.S. Interestingly, when used for drug resistance studies, culture of the three MM cell lines in microgels showed close agreement in revealing the role of acrylic acid in resistance to anti-MM drugs such as dexamethasone and bortezomib. This work presents a unique platform for the in vitro modeling of non-solid tumors since it allows keeping non-adherent cells in suspension conditions but in a 3D context that can be easily tuned with different functionalizations.This work was funded by the Spanish State Research Agency (AEI) through the PID2019-106099RB-C41/AEI/10.13039/501100011033 Project.

Biomimetic microspheres for 3D mesenchymal stem cell culture and characterization
[EN] Stem cells reside in niches, specialized microenvironments that sustain and regulate their fate. Extracellular matrix (ECM), paracrine factors or other cells are key niche regulating elements. As the conventional 2D cell culture lacks these elements, it can alter the properties of naive stem cells. In this work we designed a novel biomimetic microenvironment for cell culture, consisting of magnetic microspheres, prepared with acrylates and acrylic acid copolymers and functionalized with fibronectin or hyaluronic acid as ECM coatings. To characterize cell proliferation and adhesion, porcine mesenchymal stem cells (MSCs) were grown with the different microspheres. The results showed that the 3D environments presented similar proliferation to the 2D culture and that fibronectin allows cell adhesion, while hyaluronic acid hinders it. In the 3D environments, cells reorganize the microspheres to grow in aggregates, highlighting the advantages of microspheres as 3D environments and allowing the cells to adapt the environment to their requirements.PROMETEO/2016/063 project is acknowledged.
