Incidencia de los estilos educativos parentales en la repitencia escolar en adolescentes

School repetition is a risk factor for the adolescent population, due to the negative connotation implied by not promoting the student to the next grade, affecting his or her mental health and interpersonal relationships. Thus, it is important to know the role of the family as the main socializing context of adolescents in school performance, understanding the incidence of parental educational styles in school repetition according to the experiences of adolescents between 12 and 17 years of age who participate in a Christian church in Villavicencio. The present study is qualitative of phenomenological type, with a sample of 10 adolescents who have presented school repetition in one or more grades in the last two years, with whom a focus group was carried out to generate an interaction on their educational and family experiences. As a result, a greater incidence of permissive and negligent parental educational styles in school repetition was obtained; corresponding to the theoretically established characteristics of parents and children under these two types of parental educational styles, so that the strategies and behavioral preferences of parents in parenting, affect the academic results of adolescents.  La repitencia escolar constituye un factor de riesgo para la población adolescente, debido a la connotación negativa que implica la no promoción del estudiante al siguiente grado escolar, afectando su salud mental y sus relaciones interpersonales.

Nonstoichiometry driven ferromagnetism in double perovskite La2Ni1-xMn1+ xO6 insulating thin films

This is an open access article published under an ACS AuthorChoice License. See Standard ACS AuthorChoice/Editors' Choice Usage AgreementIn this work we report on the epitaxial growth of LaNiMnO double perovskite thin films on top of (001) oriented SrTiO substrates by RF magnetron sputtering. The influence of oxygen pressure (P O) and growth temperature on the microstructure, stoichiometry of the films, and magnetic and transport properties is thoroughly investigated. It is found that high oxygen pressure promotes the growth of stoichiometric films, with a Ni/Mn ratio almost equal to 1. However, these films exhibit poor ferromagnetic properties with respect to the expected optimum values corresponding to ferromagnetic ordering mediated by superexchange interaction between Mn and Ni according to the Goodenough-Kanamori rules. Most interestingly, films grown at low P O exhibit Ni/Mn ratios below 1, but ferromagnetic properties close to the optimal ones. The valence balance between Ni and Mn ions in nonstoichiometric sample has been elucidated by X-ray absorption spectroscopy. The results indicate that Ni deficiency plays a crucial role in the puzzling insulating ferromagnetic behavior observed in nonstoichiometric samples

Developing speaking competences in technical English for Spanish civil engineering students

[EN] Traditionally, Spanish schools of civil engineering provide their students a class on “Technical English” in order to develop their language skills. However, this class does not cover all the skills that the student would need in the labor market and mainly focuses in the reading and writing skills, and in a lower degree in the speaking and listening ones. This paper proposes a series of innovative and informal training activities (cine-forum on technical civil engineering topics and role playing on real professional situations) that allow Spanish civil engineering students to develop English skills that can rarely be worked in the classroom (i.e. speaking, negotiating and conversing), encouraging debate, participation, and fostering their self-confidence to speak about technical-English topics in public. Although the students’ level of English is much lower than expected, they all agree on the importance of technical English for their future career. The results also show the students’ lack in skills that are difficult to train in regular classes (speaking and talking). Consequently, this situation would require to provide complementary activities like the ones suggested in this project in order to develop these skills and increase the students’ demand for engineering classes taught in English.Romero De Ávila Serrano, V.; Diaz García, S.; Asensio Sánchez, L.; Lozano Galant, JA.; Moyano Enríquez De Salamanca, A.; Porras Soriano, R.; Poveda Bautista, E....

Application of 3D images for the interpretation of bryophytes in the teaching of Botany

Los dos «Proyectos de Innovación Educativa» concedidos, el primero por el Vicerrectorado de Calidad Institucional e Innovación Educativa de la Universidad de La Laguna (ULL) en la convocatoria 2014-2015 y el segundo por el actual Vicerrectorado de Docencia en la convocatoria 2015-2016, a tres profesoras del Área de Botánica, implicadas en la docencia de esta materia en 3 asignaturas («Botánica 1», «Botánica» y «Botánica y Fisiología Vegetal») de 3 titulaciones de la ULL (Grado en Biología, Grado en Ciencias Ambientales y Grado en Farmacia respectivamente), nos han permitido contratar los servicios de una diseñadora gráfica para la elaboración de las imágenes 3D de la parte del «Manual de prácticas de Botánica on-line» correspondiente a los «Briófitos». En el primer proyecto (octubre 2014-noviembre 2015) abordamos los «Briófitos foliosos» y en el segundo (octubre 2015-noviembre 2016) los «Briófitos talosos». Dado que el alumnado, en el entorno virtual, ya dispone de la primera parte del manual dedicada a los «Briófitos foliosos», en este trabajo además de dar a conocer este nuevo recurso didáctico, presentamos la valoración inicial de su uso y acogida por parte del alumnado en las prácticas de laboratorio de la asignatura «Botánica» del Grado de Ciencias Ambientales. Dicha evaluación se realizó mediante un cuestionario anónimo, usando sistemas de respuesta personal (clickers). Los resultados obtenidos nos permiten afirmar que las ilustraciones 3D para las cuales se pidió la financiación han despertado el interés del alumnado, les han servido para comprender mejor la terminología y conceptos del manual, y éste a su vez está estructurado de acuerdo con las prácticas y les ha sido útil en su proceso de aprendizajeThe two «Educational Innovation Projects» awarded by the Vicechancellor for Institutional Quality and Educational Innovation of the University of La Laguna (ULL) in the 2014-2015 call, and by the current Vice-chancellor for Teaching in the 2015-2016 call to three professors of the Botany area involved in the teaching of this discipline in 3 subjects («Botany 1», «Botany» and «Botany and Plant Physiology») of 3 ULL degrees (Degree in Biology, Environmental Sciences and Pharmacy, respectively), have allowed us to hire the services of a graphic designer for the elaboration of the 3D images of the part of the «Manual of practices of Botany on-line» corresponding to the «Bryophytes». In the first project (October 2014-November 2015) we addressed the «foliate bryophytes» while the «Thallose bryophytes» were addressed in the second (October 2015-November 2016). Since the students already had the first part of the manual dedicated to the «Foliose bryophytes» in their virtual classroom, in this work, apart from presenting this new didactic resource, we present the initial assessment of its use and acceptance by part of the students in the laboratory practices of the subject «Botany» of the Degree of Environmental Sciences. This evaluation was developed using an anonymous questionnaire carried out with personal response systems (clickers). The obtained results allow us to affirm that the 3D illustrations for which funding was requested, have aroused students’ interest, have helped them to better understand the terminology and concepts of the manual which is structured in accordance with the practices and has been useful to them in their learning process

Three double-dose reinforced hepatitis B revaccination scheme for patients with cirrhosis unresponsive to the standard regimen: an open-label randomised clinical trial

© Author(s) (or their employer(s)) 2024. No commercial re-use. See rights and permissions. Published by BMJ.[Objective] We aimed to compare the response rates between two different hepatitis B virus vaccination schedules for cirrhotic subjects who were non-responders to the first three 40 µg doses (month 0-1-2), and identify factors associated with the final response.[Design] A total of 120 cirrhotic patients (72.5% decompensated) were randomised at a 1:1 ratio to receive a single 40 µg booster vaccination at month 6 (classical arm) versus an additional round of three new 40 µg doses administered at monthly intervals (experimental arm). The main outcome was the rate of postvaccinal anti-hepatitis B surface antibodies levels ≥10 mIU/mL.[Results] Efficacy by ITT analysis was higher in the experimental arm (46.7%) than in the classical one (25%); OR 2.63, p=0.013. The experimental arm increased response rates compared with the classical one from 31% to 68% (OR 4.72; p=0.007), from 24.4% to 50% (OR 3.09; p=0.012) and from 24.4% to 53.8% (OR 3.62; p=0.007), in Child A, Model for End-Stage Liver Disease (MELD) <15 and MELD-Na<15 patients, respectively. Patients with more advanced liver disease did not benefit from the reinforced scheme. Both regimens showed similar safety profiles. Multivariable analysis showed that the experimental treatment was independently response associated when adjusted across three logistic regression models indicating equivalent cirrhosis severity.[Conclusion] For cirrhotic patients, the revaccination of non-responders to the first three dose cycle, with three additional 40 µg doses, achieved significantly better response rates to those obtained with an isolated 40 µg booster dose.[Trial registration number] NCT01884415.This study project was awarded competitive public funding for Independent Research from the Spanish Government Ministry of Health and Social Politics in 2011 via the Carlos III Health Institute (EC11-452).

SARS-CoV-2 viral load in nasopharyngeal swabs is not an independent predictor of unfavorable outcome

The aim was to assess the ability of nasopharyngeal SARS-CoV-2 viral load at first patient’s hospital evaluation to predict unfavorable outcomes. We conducted a prospective cohort study including 321 adult patients with confirmed COVID-19 through RT-PCR in nasopharyngeal swabs. Quantitative Synthetic SARS-CoV-2 RNA cycle threshold values were used to calculate the viral load in log10 copies/mL. Disease severity at the end of follow up was categorized into mild, moderate, and severe. Primary endpoint was a composite of intensive care unit (ICU) admission and/or death (n = 85, 26.4%). Univariable and multivariable logistic regression analyses were performed. Nasopharyngeal SARS-CoV-2 viral load over the second quartile (≥ 7.35 log10 copies/mL, p = 0.003) and second tertile (≥ 8.27 log10 copies/mL, p = 0.01) were associated to unfavorable outcome in the unadjusted logistic regression analysis. However, in the final multivariable analysis, viral load was not independently associated with an unfavorable outcome. Five predictors were independently associated with increased odds of ICU admission and/or death: age ≥ 70 years, SpO2, neutrophils > 7.5 × 103/µL, lactate dehydrogenase ≥ 300 U/L, and C-reactive protein ≥ 100 mg/L. In summary, nasopharyngeal SARS-CoV-2 viral load on admission is generally high in patients with COVID-19, regardless of illness severity, but it cannot be used as an independent predictor of unfavorable clinical outcome

Autoantibodies against type I IFNs in patients with critical influenza pneumonia

In an international cohort of 279 patients with hypoxemic influenza pneumonia, we identified 13 patients (4.6%) with autoantibodies neutralizing IFN-alpha and/or -omega, which were previously reported to underlie 15% cases of life-threatening COVID-19 pneumonia and one third of severe adverse reactions to live-attenuated yellow fever vaccine. Autoantibodies neutralizing type I interferons (IFNs) can underlie critical COVID-19 pneumonia and yellow fever vaccine disease. We report here on 13 patients harboring autoantibodies neutralizing IFN-alpha 2 alone (five patients) or with IFN-omega (eight patients) from a cohort of 279 patients (4.7%) aged 6-73 yr with critical influenza pneumonia. Nine and four patients had antibodies neutralizing high and low concentrations, respectively, of IFN-alpha 2, and six and two patients had antibodies neutralizing high and low concentrations, respectively, of IFN-omega. The patients' autoantibodies increased influenza A virus replication in both A549 cells and reconstituted human airway epithelia. The prevalence of these antibodies was significantly higher than that in the general population for patients 70 yr of age (3.1 vs. 4.4%, P = 0.68). The risk of critical influenza was highest in patients with antibodies neutralizing high concentrations of both IFN-alpha 2 and IFN-omega (OR = 11.7, P = 1.3 x 10(-5)), especially those <70 yr old (OR = 139.9, P = 3.1 x 10(-10)). We also identified 10 patients in additional influenza patient cohorts. Autoantibodies neutralizing type I IFNs account for similar to 5% of cases of life-threatening influenza pneumonia in patients <70 yr old

Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)

Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio
