¿Forma en sostenibilidad el sistema universitario español? Visión del alumnado de cuatro universidades

For more than a decade, various national and international initiatives have emerged so that universities can assume a leadership role in order to promote education for sustainable development and to respond to the global challenges of today’s society. It is necessary to analyze the effectiveness of these initiatives, and to ask ourselves whether or not universities are training their students to face these challenges with responsibility.This is one of the objectives of the EDINSOST project. Within the framework of EDINSOST, we have carried out qualitative research, developing focus groups with students in their final years at different universities and different academic profiles. This has allowed us to integrate the perspective of university students into our analysis. In this paper, we present the most relevant contributions in relation to the students’ vision of sustainability, their formative experience in the university and their opinion on how it could be improved. Results show that the sustainability training provided by university is insufficient: students do not feel prepared to integrate sustainability into their professional activity. However, they consider it essential that universities should include sustainability in their academic curricula, and they emphasize the importance of using active methodologies that connect students with reality and encourage reflection.The research shows that there is a lot of work to be done in order to integrate sustainability into university education. Students’ proposals are aligned with those of experts in education for sustainability. To carry them out requires both teacher training and commitment, as well as institutional involvement.Desde hace más de una década, existen diversas iniciativas internacionales y nacionales para que las universidades asuman un rol de liderazgo para promover una educación para el desarrollo sostenible y dar respuestas a los retos globales de la sociedad actual. Es preciso analizar la efectividad de esas iniciativas y preguntarnos si las universidades están formando a sus estudiantes para afrontar con responsabilidad dichos retos.Éste es uno de los objetivos del proyecto EDINSOST, dentro de cuyo marco hemos llevado a cabo una investigación de tipo cualitativa, desarrollando grupos de discusión con estudiantes de últimos cursos de distintas universidades y perfiles académicos. Esto nos ha permitido integrar en nuestros análisis la perspectiva del alumnado universitario.En este artículo se presentan las aportaciones más relevantes en relación a la visión de los estudiantes sobre la sostenibilidad, su experiencia formativa en la universidad y su opinión sobre cómo podría mejorarse. Los resultados muestran que la formación en sostenibilidad que aporta la universidad es insuficiente, y que los estudiantes no se sienten preparados para integrar la sostenibilidad en su actividad profesional. Sin embargo, consideran fundamental que la universidad incluya la sostenibilidad en sus currículos académicos, y enfatizan la importancia de emplear metodologías activas que conecten al alumnado con la realidad y fomenten la reflexión.La investigación muestra que queda mucho trabajo por hacer para integrar la sostenibilidad en la formación universitaria. Las propuestas del alumnado están alineadas con las de los expertos en educación para la sostenibilidad, y para llevarlas a cabo se requiere tanto la formación y compromiso del profesorado como la implicación institucional

High-Dimensional Analysis of Single-Cell Flow Cytometry Data Predicts Relapse in Childhood Acute Lymphoblastic Leukaemia

B-cell Acute Lymphoblastic Leukaemia is one of the most common cancers in childhood, with 20% of patients eventually relapsing. Flow cytometry is routinely used for diagnosis and follow-up, but it currently does not provide prognostic value at diagnosis. The volume and the high-dimensional character of this data makes it ideal for its exploitation by means of Artificial Intelligence methods. We collected flow cytometry data from 56 patients from two hospitals. We analysed differences in intensity of marker expression in order to predict relapse at the moment of diagnosis. We finally correlated this data with biomolecular information, constructing a classifier based on CD38 expression. Artificial intelligence methods may help in unveiling information that is hidden in high-dimensional oncological data. Flow cytometry studies of haematological malignancies provide quantitative data with the potential to be used for the construction of response biomarkers. Many computational methods from the bioinformatics toolbox can be applied to these data, but they have not been exploited in their full potential in leukaemias, specifically for the case of childhood B-cell Acute Lymphoblastic Leukaemia. In this paper, we analysed flow cytometry data that were obtained at diagnosis from 56 paediatric B-cell Acute Lymphoblastic Leukaemia patients from two local institutions. Our aim was to assess the prognostic potential of immunophenotypical marker expression intensity. We constructed classifiers that are based on the Fisher's Ratio to quantify differences between patients with relapsing and non-relapsing disease. We also correlated this with genetic information. The main result that arises from the data was the association between subexpression of marker CD38 and the probability of relapse

Perfil clínico y analítico de pacientes con trombocitemia esencial y JAK2 mutado. experiencia en nuestro centro

Abstract [PB-094] Introducción: La trombocitemia esencial (TE) es una neoplasia mieloproliferativa crónica caracterizada por un aumento persistente de la cifra de plaquetas a expensas de una hiperplasia megacariocítica. Estos pacientes pueden presentar distintas mutaciones (JAK2, CALR, MPL) que se han relacionado con un curso clínico distinto de la enfermedad. El 50- 60 % de los pacientes con TE presentan la mutación V617F del gen JAK2 y se ha observado que presentan algunas características clínicas y hematimétricas similares a los pacientes con Policitemia Vera, en los que esta mutación está presente en un 95%. Pacientes y Métodos: Estudio descriptivo, retrospectivo y prospectivo unicéntrico, en el que se han analizado características clínicas y datos de laboratorio de los pacientes diagnosticados de Trombocitemia Esencial JAK2 mutado en nuestro hospital, así como las diferencias en la presentación de la enfermedad de aquellos pacientes JAK2 no mutado (incluyendo pacientes con la mutación CALR o MPL y los pacientes triple negativos). Resultados: Se han analizado 95 pacientes. De estos 35 (36, 84%) eran hombres y 60 (63, 16%) mujeres diagnosticados entre 2000 y 2017. Se analizaron las siguientes variables. Conclusiones: Es importante la caracterización molecular de estos pacientes puesto que se relaciona con la presentación clínica de la enfermedad. Como se ha descrito en la literatura, en nuestra experiencia la mutación más frecuentemente encontrada es JAK2 (V617F). En nuestra serie de casos se ha observado que la mediana de edad en estos pacientes es mayor que en el resto de grupos (excepto en el grupo con MPL, probablemente por el escaso número de pacientes). Además, se observa analíticamente un mayor nivel de hemoglobina, hematocrito y leucocitos, y una cifra menor de ferritina y de plaquetas. También encontramos la eritropoyetina descendida en 20 % de estos pacientes, sin observarse ningún caso en el resto de grupos. Desde el punto de vista clínico se observa con mayor frecuencia la aparición de fenómenos trombóticos, así como presentación de prurito

Diferencias clínicas y hematimétricas en pacientes con trombocitemia esencial y mutación para el gen de la calreticulina

Abstract [PB-090] Introducción: La identificación de la mutación somática en el gen CALR ha supuesto un avance diagnóstico en las neoplasias mieloproliferativas crónicas. Una cuarta parte de los pacientes (ptes) con trombocitemia esencial (TE) presenta dicha mutación, diferenciando dos variantes: la CALR tipo 1 (deleciones) y tipo 2 (inserciones). La TE mutada por CALR podría tratarse no solo de una entidad distinta a nivel molecular, sino también a nivel clínico-analítico. Métodos: Estudio descriptivo y prospectivo unicéntrico. Se incluyen 95 pacientes con TE diagnosticados en el Hospital Miguel Servet. Se analizan variables demográficas, características clínicas y hematimétricas en función de la biología molecular del paciente, establecimiento las diferencias observadas entre los pacientes con mutación JAK-2 y CALR (tipo 1 y tipo 2). Resultados: 35 eran hombres y 60 mujeres. Del total de pacientes, 55 presentaban la mutación JAK-2 (57, 89%), 22 la mutación CALR (23, 15%) (tipo 1: 12 ptes (46, 15%) y tipo 2: 10 ptes (38, 46%)), 5 la mutación MPL (5, 2%) y 9 eran triples negativos (9, 4%). Los ptes con TE mutada con CALR eran más jóvenes que los JAK-2, mediana de edad 65 años (29-84) y 72 años (40-96) respectivamente. Al diagnóstico, las cifras de hemoglobina y leucocitos en ptes JAK-2 eran superiores (mediana 14, 6 g/dL y 9, 30. 10³/µL) frente a CALR tipo 1 (mediana 14, 1 g/dL y 7, 78.10³/µL) y tipo 2 (14, 4 g/dL y 7, 80.10³/µL) y presentaban un recuento menor de plaquetas (mediana 744.10³/µL) frente a CALR tipo 1 (mediana 836. 10³/µL) y tipo 2 (mediana 916.10³/µL). Todos los pacientes CALR presentaban niveles normales de eritropoyetina mientras que un 18% JAK-2 presentaban niveles descendidos. 17 ptes (12, 72%) JAK-2, 3 ptes (25%) CALR tipo 1 y 1 pte (10%) CALR tipo 2 presentaban esplenomegalia. Presentaron episodio trombótico previo al diagnóstico: 5 ptes JAK- 2 (9%), de éstos 5 ptes eran hipertensos y 2 dislipémicos, 1 pte CALR tipo 1 (8, 3%), era hipertenso, dislipémico y fumador y ninguno CALR tipo 2, 1 pte era hipertenso. Tras el diagnóstico 1 pte JAK2 presentó nuevo episodio trombótico posteriormente. Al diagnóstico, 41 pacientes JAK-2 se les realizó biopsia ósea (74, 5%) con reticulina grado 1: 11 ptes (26, 82%), grado 2: 3 ptes (7, 3%) y grado 3: 0 ptes; a 11 ptes CALR tipo 1 (91, 6%) con reticulina grado 1: 3 ptes (27, 27%) y grado 2-3: 0 ptes; a 7 pacientes CALR tipo 2 (70%) con reticulina tipo 1: 3 ptes (44, 85%) y grado 2-3: 0 ptes. Conclusiones: La TE con mutación CALR parece comportarse de manera diferente en térmicos de características biológicas, hematológicas y clínicas frente a la mutación JAK2. Afecta a individuos relativamente jóvenes y se caracteriza por un recuento de plaquetas mayor pero con un riesgo trombótico inferior, especialmente los pacientes CALR tipo 2. Aunque en nuestra serie no encontramos grandes diferencias entre los subtipos de CALR, probablemente por el escaso número de ptes, creemos que ampliando la muestra existan diferencias entre ambos subgrupos que podrían implicar diferentes algoritmos terapéuticos

First evidence of multiple beta-delayed neutron emission for isotopes with A > 100

The beta-delayed neutron emission probability, P-n, of very neutron-rich nuclei allows us to achieve a better understanding of the nuclear structure above the neutron separation energy, S-n. The emission of neutrons can become the dominant decay process in neutron-rich astrophysical phenomena such as the rapid neutron capture process (r-process). There are around 600 accessible isotopes for which beta-delayed one-neutron emission (beta 1n) is energetically allowed, but the branching ratio has only been determined for about one third of them. beta 1n decays have been experimentally measured up to the mass A similar to 1 5 0, plus a single measurement of Tl-210. Concerning two-neutron emitters (beta 2n), similar to 3 0 0 isotopes are accessible and only 24 have been measured so far up to the mass A = 100. In this contribution, we report recent experiments which allowed the measurement of beta 1n emitters for masses beyond A > 200 and N > 1 2 6 and identified the heaviest beta 2n emitter measured so far, Sb-136.Peer reviewe

Measurement of the heaviest beta-delayed 2-neutron emitter : Sb-136

The beta-delayed neutron emission probability, P-n, of very exotic nuclei is crucial for the understanding of nuclear structure properties of many isotopes and astrophysical processes such as the rapid neutron capture process (r-process). In addition beta-delayed neutrons are important in a nuclear power reactor operated in a prompt sub-critical, delayed critical condition, as they contribute to the decay heat inducing fission reactions after a shut down. The study of neutron-rich isotopes and the measurement of beta-delayed one-neutron emitters (beta 1n) is possible thanks to the Rare Isotope Beam (RIB) facilities, where radioactive beams allow the production of exotic nuclei of interest, which can be studied and analyzed using specific detection systems. This contribution reports two recent measurements of beta-delayed neutron emitters which allowed the determination of half-lives and the neutron branching ratio of isotopes in the mass region above A = 200 and N > 126, and a second experiment which confirmed Sb-136 as the heaviest double neutron emitter (beta 2n) measured so far.The beta-delayed neutron emission probability, P-n, of very exotic nuclei is crucial for the understanding of nuclear structure properties of many isotopes and astrophysical processes such as the rapid neutron capture process (r-process).

The evolution of the ventilatory ratio is a prognostic factor in mechanically ventilated COVID-19 ARDS patients

Background: Mortality due to COVID-19 is high, especially in patients requiring mechanical ventilation. The purpose of the study is to investigate associations between mortality and variables measured during the first three days of mechanical ventilation in patients with COVID-19 intubated at ICU admission. Methods: Multicenter, observational, cohort study includes consecutive patients with COVID-19 admitted to 44 Spanish ICUs between February 25 and July 31, 2020, who required intubation at ICU admission and mechanical ventilation for more than three days. We collected demographic and clinical data prior to admission; information about clinical evolution at days 1 and 3 of mechanical ventilation; and outcomes. Results: Of the 2,095 patients with COVID-19 admitted to the ICU, 1,118 (53.3%) were intubated at day 1 and remained under mechanical ventilation at day three. From days 1 to 3, PaO2/FiO2 increased from 115.6 [80.0-171.2] to 180.0 [135.4-227.9] mmHg and the ventilatory ratio from 1.73 [1.33-2.25] to 1.96 [1.61-2.40]. In-hospital mortality was 38.7%. A higher increase between ICU admission and day 3 in the ventilatory ratio (OR 1.04 [CI 1.01-1.07], p = 0.030) and creatinine levels (OR 1.05 [CI 1.01-1.09], p = 0.005) and a lower increase in platelet counts (OR 0.96 [CI 0.93-1.00], p = 0.037) were independently associated with a higher risk of death. No association between mortality and the PaO2/FiO2 variation was observed (OR 0.99 [CI 0.95 to 1.02], p = 0.47). Conclusions: Higher ventilatory ratio and its increase at day 3 is associated with mortality in patients with COVID-19 receiving mechanical ventilation at ICU admission. No association was found in the PaO2/FiO2 variation

Clustering COVID-19 ARDS patients through the first days of ICU admission. An analysis of the CIBERESUCICOVID Cohort

Background Acute respiratory distress syndrome (ARDS) can be classified into sub-phenotypes according to different inflammatory/clinical status. Prognostic enrichment was achieved by grouping patients into hypoinflammatory or hyperinflammatory sub-phenotypes, even though the time of analysis may change the classification according to treatment response or disease evolution. We aimed to evaluate when patients can be clustered in more than 1 group, and how they may change the clustering of patients using data of baseline or day 3, and the prognosis of patients according to their evolution by changing or not the cluster.Methods Multicenter, observational prospective, and retrospective study of patients admitted due to ARDS related to COVID-19 infection in Spain. Patients were grouped according to a clustering mixed-type data algorithm (k-prototypes) using continuous and categorical readily available variables at baseline and day 3.Results Of 6205 patients, 3743 (60%) were included in the study. According to silhouette analysis, patients were grouped in two clusters. At baseline, 1402 (37%) patients were included in cluster 1 and 2341(63%) in cluster 2. On day 3, 1557(42%) patients were included in cluster 1 and 2086 (57%) in cluster 2. The patients included in cluster 2 were older and more frequently hypertensive and had a higher prevalence of shock, organ dysfunction, inflammatory biomarkers, and worst respiratory indexes at both time points. The 90-day mortality was higher in cluster 2 at both clustering processes (43.8% [n = 1025] versus 27.3% [n = 383] at baseline, and 49% [n = 1023] versus 20.6% [n = 321] on day 3). Four hundred and fifty-eight (33%) patients clustered in the first group were clustered in the second group on day 3. In contrast, 638 (27%) patients clustered in the second group were clustered in the first group on day 3.Conclusions During the first days, patients can be clustered into two groups and the process of clustering patients may change as they continue to evolve. This means that despite a vast majority of patients remaining in the same cluster, a minority reaching 33% of patients analyzed may be re-categorized into different clusters based on their progress. Such changes can significantly impact their prognosis
