Comparative outcomes of surgical versus percutaneous arteriovenous fistulas: a prospective study
No full textBackground. For patients undergoing haemodialysis (HD), the choice of vascular access is pivotal in determining
morbidity and mortality outcomes. Traditionally, native arteriovenous fistulas (AVFs) have been created through surgical
procedures. However, percutaneous endovascular devices for AVF formation have been introduced into clinical practice,
showing promising early results. This study aims to compare the outcomes of endovascular AVFs (endoAVFs) created
using the WavelinQ EndoAVF System (BD, Franklin Lakes, NJ, USA) and surgically created radiocephalic (RC) AVFs in
real-world settings.
Methods. This prospective, single-centre, two-arm study included patients who underwent the creation of either an
endoAVF using the WavelinQ EndoAVF System or an RC AVF at a university hospital between December 2021 and August
2023.
Results. A total of 20 patients who underwent an endoAVF and 40 who underwent a surgical AVF (SAVF) were included.
Technical success was 100% in both groups. A total of 75% of the endoAVFs and 60% of the SAVFs met the criteria for
physiological suitability. Among the AVFs that reached physiological suitability, the cannulation rate was 66% for the
endoAVFs and 70.86% for the SAVFs. At the 6-month follow-up, the primary and cumulative patency rates were 65% and
75% in the endoAVF group and 57.5% and 60% in the SAVF group, respectively. At 12 months, these rates were 50% and
70% in the endoAVF group and 50% and 60% in the SAVF group, respectively. No serious adverse events were observed.
The reintervention rate was 0.25/patient/year in the endoAVF group and 0.1 in the SAVF group.
Conclusion. The results of our study showed endoAVFs may be a safe and effective alternative to RC AVFs, showing high
rates of technical success and patency with a low rate of reinterventions and complications
Frequency Selection in Continuous Wave Indirect Time-of-Flight Cameras
No full textContinuous wave indirect time-of-flight cameras obtain depth images by emitting a modulated continuous light wave and measuring the delay of the received signal. The wave is modulated sequentially using multiple frequencies. In this article, a new algorithm for the identification of the optimum set of frequencies is presented. The optimization problem is modeled with multiple objective criteria: minimizing the number of unwrapping errors and maximizing the distance estimation precision under given constraints such as the maximum modulated frequency or the minimum unambiguous range of working distances. The dependence of the proposed optimization on each constraint and the performance of the method are analyzed using Monte Carlo simulations
Hacia un diagnóstico territorial basado en el conocimiento local y en la percepción de la población para la ordenación de municipios: el caso de la Asociación de Municipios del Norte de Morazán (AMNM) en El Salvador, Centro América.
No full textModelo metodológico de diagnóstico de un sistema territorial basado en el conocimiento local y en la percepción de la población para la generación de información terrritorial que pueda generar insumos al diagnóstico técnico. La metodología de diagnóstico territorial propuesta en la investigación prioriza el conocimiento de la población y su percepción sobre el sistema territorial en el que nace y desarrolla todo su ciclo de vida generacionalmente, realizando una lectura del medio físico a partir de ese conocimiento, así como una priorización de las necesidades más sentidas, a partir de su propia visión sobre el modelo de desarrollo de su región, en función de encontrar alternativas que posibiliten una mejora en la calidad de vida de sus habitantes, a través del cuidado y la protección de los recursos naturales, la mejora en la calidad de servicios públicos que reciben de las instituciones y los espacios de participación ciudadana.Design of a methodological model for territorial diagnosis for territorial planning based on local knowledge and the population's perception of their region, as a complement to the technical diagnosis, applied in the territorial system of the Association of Municipalities of Northern Morazán in El Salvador, Central America.Programa de Doctorat en Desenvolupament Local i Cooperació Internaciona
Emotional reasoning as a transdiagnostic process in patients with public speaking anxiety. Evaluation and design of a psychological intervention.
No full textDoctorat internacionalThe transdiagnostic perspective suggests that psychological disorders may share underlying processes. Harvey’s model identifies Emotional Reasoning (ER) as one such mechanism, whereby emotions are used to judge reality, leading individuals to equate anxiety with danger. This study examined ER in Public Speaking Anxiety (PSA), a prevalent condition. A systematic review revealed evidence of ER biases in anxiety disorders, though not in depression. Subsequently, the Emotional Reasoning Public Speaking Anxiety Scale (ERPSAS) was developed and validated with a Spanish sample, demonstrating strong reliability. Findings showed that individuals with PSA judged anxious scenarios as more dangerous than objectively threatening ones, confirming the presence of ER bias. Additionally, a self-administered online intervention, HablaRÉ, was created to reduce ER bias. A feasibility study indicated high usability, satisfaction, and adherence (94%), alongside preliminary improvements in ER and PSA symptoms. These findings support the role of ER in PSA and provide novel tools for assessment and intervention.Programa de Doctorat en Psicologi
A declarative approach for interactive process discovery in the clinical domain
No full textObjective: Process Mining (PM) is an established discipline with increasing adoption in the clinical domain. In this context, PM seeks to infer clinical processes from healthcare data collected in the Electronic Health Record. However, the particularities of clinical practice cause that, in most cases, the processes obtained result in an intricate network that hardly corresponds to clinical algorithms and, thus, are difficult to understand for clinical and IT personnel. To address these problems, our aim is to incorporate specialized clinical knowledge into the PM discovery algorithm. Methods: We propose a declarative approach to interactive process discovery in the clinical domain. Concretely, we present a set of declarative techniques that allows clinicians to incorporate their knowledge in the process, based on the Declare formalism. Results: The results of this work encompass both the declarative interactive approach and its implementation in the I-PALIA PM discovery algorithm, as well as an application to a use case for the treatment of prostate cancer. This application demonstrates that the implemented techniques are useful in managing typical problems that arise when applying PM methods to the clinical domain. Conclusion: This work proposes a novel approach with techniques for interactive process discovery in the clinical domain. This approach not only allows the clinical expert to interactively incorporate specialized knowledge into the PM algorithm, but also serves to obtain process models that are more comprehensible and better resemble treatment procedures.Funding for open access charge: CRUE-Universitat Jaume
Coeducar en Círculos Restaurativos: promover masculinidades proigualitarias y pactos de buenos tratos
No full textTreball final de Màster Universitari en Igualtat i Gènere en l'Àmbit Públic i Privat (Pla de 2013). Codi: SRM042. Curs acadèmic 2024-2025El presente Trabajo de Final de Máster (TFM) plantea una intervención educativa para fomentar masculinidades igualitarias y buenos tratos entre iguales, dirigida a centros de educación secundaria. Su objetivo principal es sensibilizar desde la pedagogía feminista y del cuidado, a través del Enfoque Restaurativo Global (ERG). Combina metodologías participativas y favorece elaprendizaje vivencial desde la práctica dialógica. Busca fomentar el pensamiento crítico sobre la construcción cultural del género y sus consecuencias sociales, visibilizar referentes de masculinidades pro igualitarias y favorecer relaciones personales sanas y buenos tratos entre jóvenes adolescentes.
Los datos de estudios oficiales elaborados por el Centro de Investigaciones Sociológicas (CIS) y el Barómetro de la Juventud evidencian que poner en marcha el proyecto "Coeducar en Círculos Restaurativos: promover masculinidades pro igualitarias y pactos de buenos tratos" responde a la necesidad de trabajar con adolescentes temas relacionados con la igualdad y la convivencia positiva.
El marco teórico que aborda este trabajo incluye, de manera sucinta, desde la teoría sexo-género abordada por Simone de Beauvoir o Gayle Rubin; las teorías sobre masculinidades de Raewyn Connell o Luis Bonino y las aportaciones al respecto de Joan Sanfélix; y el tratamiento de las masculinidades desde la coeducación de Miguel Ángel Arconada. También se destacan aportaciones de otras autoras como Rita Segato, Marina Subirats, Carmen Ruiz Repullo. Mónica Albertí, Belinda Hopkins y Jean Smith que cierran las aportaciones teóricas que justifican este proyecto.
El Proyecto Coeducar en Círculos Restaurativos supone una estrategia educativa:
- Con impacto global ya que implica a tres pilares fundamentales de la comunidad educativa: alumnado, profesorado y familias.
- Accesible y adaptada a la necesidad del centro.
- De relevancia, ya que cubre una necesidad social respondiendo a un contexto en el que la igualdad está siendo cuestionada e impugnada por sectores concretos de la población.
- Integral que aglutina acciones de sensibilización, formación con el objetivo de favorecer escuelas coeducadoras donde se trabaje los vínculos entre chicas y chicos desde el respeto y los buenos tratos
Newton-Okounkov bodies and Picard numbers on surfaces
No full textWe study the shapes of all Newton–Okounkov bodies ∆v(D) of a given big divisor D on
a surface S with respect to all rank 2 valuations v of K(S).
We obtain upper bounds for, and in many cases we determine exactly, the possible numbers of
vertices of the bodies ∆v(D). The upper bounds are expressed in terms of Picard numbers and they
are birationally invariant, as they do not depend on the model S˜ where the valuation v becomes a
flag valuation.
We also conjecture that the set of all Newton–Okounkov bodies of a single ample divisor D
determines the Picard number of S, and prove that this is the case for Picard number 1, by an
explicit characterization of surfaces of Picard number 1 in terms of Newton–Okounkov bodies
Estimar el que és nostre, estimar la nostra identitat. Reivindiquem el valencià
No full textMàster Universitari en Professor/a d'Educació Secundària Obligatòria i Batxillerat, Formació Professional i Ensenyaments d'Idiomes. Codi: SAP439. Curs acadèmic: 2024/2025Afortunadament, la gran majoria dels centres educatius s'estan movent cap a una perspectiva més crítica, igualitària i inclusiva. El professorat està fent una gran tasca per garantir que els xiquets i les xiquetes reben la millor educació possible, basada en valors com el respecte. Tanmateix, sembla que encara falta molt de camí per recórrer pel que fa a la nostra llengua, ja que, actualment, la tendència a parlar en valencià, especialment entre la joventut, és bastant negativa, la qual cosa deixa en evidència el seu futur.
La substitució lingüística avança i molts adolescents, sovint, abandonen l’ús del valencià fora de l’àmbit acadèmic per pressions socials, falta de referents i un context que afavoreix el castellà. En aquest projecte, que tindrà una durada de tres cursos i que sempre partirà dels fets i experiències de la realitat en els centres educatius, es reivindicarà el valencià com a llengua plena, útil i estimada, i es proposaran una sèrie d’accions per recuperar-ne l’ús viu als màxims llocs possibles.
D’aquesta manera, s’intentaran posar en pràctica propostes que planten cara a aquest autoodi. Les seues pàgines respiren crítica, possibilitat i desig amb la mirada posada en un futur, en què parlar valencià siga un acte natural i digne.Fortunately, schools are moving towards a more critical, egalitarian and inclusive perspective. Teachers are doing a great job to ensure that children receive the best possible education, based on values such as respect. However, it seems that there is still a long way to go in terms of our language, since, currently, the tendency to speak in Valencian, especially among young people, is quite negative, which leaves its future evident.
Linguistic substitution is progressing, and often, many adolescents abandon the use of Valencian outside the academic field due to social pressures, lack of references and a context that favors Spanish. In this project, which will last three years and will always start from the facts and experiences of reality in educational centers, Valencian will be claimed as a full, useful and beloved language, and a series of actions will be proposed to recover its live use in the maximum possible places. In this way, attempts will be made to implement proposals that address this self-hatred. His pages breathe criticism, possibility and desire with his eyes set on a future, in which speaking Valencian is a natural and dignified act

Multifactorial stress combination as a driving force in the decline of uni- and multicellular organisms
No full textCompendi d'articles, Doctorat internacionalThis doctoral thesis investigates how plants respond to multifactorial environmental stress conditions (MFSC) caused by climate change, focusing on both the crop Solanum lycopersicum (tomato) and the alga Chlamydomonas reinhardtii. Physiological, transcriptomic, metabolomic, and proteomic analyses revealed that stress complexity leads to declining photosynthetic performance, increased oxidative damage, and metabolic reprogramming in tomato. Jasmonic acid was shown to be crucial for mitigating oxidative stress. In C. reinhardtii, MFSC impaired growth and chlorophyll content, with the ROS-deficient mutant rbo1 showing reduced extracellular H₂O₂ and increased cell aggregation. Transcriptomic profiling identified conserved stress-responsive genes across species, suggesting a shared molecular signature. Proteomic and metabolomic data indicated adaptations prioritizing redox balance and osmoprotection. Overall, this work highlights conserved stress response pathways in unicellular and multicellular systems, offering targets for enhancing crop resilience.Programa de Doctorat en Cièncie
