    With this study, we aim to test the predictive relationships between determinants of major choice (DMC) and academic expectations (AEs) and to analyze gender differences, using six items of the Determinants of Major Choice Scale and the Academic Perceptions Questionnaire to assess AEs. A convenience sample of Portuguese (n = 839) and Spanish (n = 1,001) first-year students (age-range = 17–23 years), mostly composed of women (56.9%, n = 1,047), was selected from two public universities. The invariance of the multivariate regression model with latent variables of the effect of DMC on AEs, with determinants linked to Personal Characteristics (PCs; e.g., capacities) and Mediating Agents (MAs; e.g., parents) as AE predictors, was tested across gender with LISREL. The invariance test of the multivariate regression model across gender fit the data well and revealed an equivalence of slopes between women and men, which allows a unique interpretation of the model’s predictive relationships for both genders. We also found statistically significant predictive relationships of PCs for six AE factors and MAs for five AE factors. The results showed theoretical relationships with the selfdetermination theory. At a practical level, they indicated the importance of PCs and MAs to design AE intervention programs in Higher Education (HE) institution

    BACKGROUND: Computerised databases of primary care clinical records are widely used for epidemiological research. In Catalonia, the Information System for the Development of Research in Primary Care (SIDIAP) aims to promote the development of research based on high-quality validated data from primary care electronic medical records. OBJECTIVE: The purpose of this study is to create and validate a scoring system (Registry Quality Score, RQS) that will enable all primary care practices (PCPs) to be selected as providers of researchusable data based on the completeness of their registers. METHODS: Diseases that were likely to be representative of common diagnoses seen in primary care were selected for RQS calculations. The observed/expected cases ratio was calculated for each disease. Once we had obtained an estimated value for this ratio for each of the selected conditions we added up the ratios calculated for each condition to obtain a final RQS. Rate comparisons between observed and published prevalences of diseases not included in the RQS calculations (atrial fibrillation, diabetes, obesity, schizophrenia, stroke, urinary incontinence and Crohn's disease) were used to set the RQS cutoff which will enable researchers to select PCPs with research-usable data. RESULTS: Apart from Crohn's disease, all prevalences were the same as those published from the RQS fourth quintile (60th percentile) onwards. This RQS cut-off provided a total population of 1 936 443 (39.6% of the total SIDIAP population). CONCLUSIONS: SIDIAP is highly representative of the population of Catalonia in terms of geographical, age and sex distributions. We report the usefulness of rate comparison as a valid method to establish research-usable data within primary care electronic medical records

    Objectives: The primary objectives of the study are: 1. To assess the effect of hydroxychloroquine (HCQ) in reducing SARS-CoV-2 viral shedding by PCR in infected pregnant women with mild symptoms. 2. To assess the efficacy of HCQ to prevent SARS-CoV-2 infection in pregnant women in contact with an infected or suspected case. 3. To evaluate the effect of HCQ in preventing the development of the COVID-19 disease in asymptomatic SARS-CoV-2-infected pregnant women. The secondary objectives are: 1. To determine the effect of HCQ on the clinical course and duration of the COVID-19 disease in SARS-CoV-2-infected pregnant women. 2. To determine the impact of HCQ on the risk of hospitalization and mortality of SARS-CoV-2-infected pregnant women. 3. To assess the safety and tolerability of HCQ in pregnant women. 4. To describe the clinical presentation of SARS-CoV-2 infection during pregnancy. 5. To describe the effects of maternal SARS-CoV-2 infection on pregnancy and perinatal outcomes by treatment group. 6. To determine the risk of vertical transmission (intra-utero and intra-partum) of SARS-CoV-2. Trial design: Randomized double-blind placebo-controlled two-arm multicentre clinical trial to evaluate the safety and efficacy of HCQ to prevent and/or minimize SARS-CoV-2 infection during pregnancy. Participants will be randomized to receive a 14-day oral treatment course of HCQ or placebo, ratio 1:1. Participants: Study population: pregnant women undergoing routine prenatal follow up or attending emergency units at the participating hospitals who report either symptoms/signs suggestive of COVID-19 disease or close contact with a suspected or confirmed COVID-19 case. Inclusion criteria Women will be invited to participate in the trial and sign an informed consent if they meet the following inclusion criteria. •Presenting with fever (≥37.5°C) and/or one mild symptom suggestive of COVID-19 disease (cough, dyspnoea, chills, odynophagia, diarrhoea, muscle pain, anosmia, dysgeusia, headache) OR being contact*of a SARS-CoV-2 confirmed or suspected case in the past 14 days •More than 12 weeks of gestation (dated by ultrasonography) •Agreement to deliver in the study hospitals Exclusion criteria •Known hypersensitivity to HCQ or other 4-amonoquinoline compounds •History of retinopathy of any aetiology •Concomitant use of digoxin, cyclosporine, cimetidine •Known liver disease •Clinical history of cardiac pathology including known long QT syndrome •Unable to cooperate with the requirements of the study •Participating in other intervention studies •Delivery onset (characterized by painful uterine contractions and variable changes of the cervix, including some degree of effacement and slower progression of dilatation up to 5 cm for first and subsequent labours) The study participants will be stratified by clinical presentation and SARS-CoV-2 PCR results. Assignment of participants to study groups will be as follows: •SARS-CoV-2-PCR confirmed, infected pregnant women: a. symptomatic (n=100) b. asymptomatic (n=100) •SARS-CoV-2 PCR negative pregnant women in contact*with a SARS-CoV-2-infected confirmed or suspected case (n=514).*The ECDC definition of close contact will be followed. The trial will be conducted in five hospitals in Spain: Hospital Clínic of Barcelona, Hospital Sant Joan de Déu and Hospital de la Santa Creu i Sant Pau, in Barcelona, and HM Puerta del Sur and Hospital Universitario de Torrejón, in Madrid. Intervention and comparator: Participants will be randomized to HCQ (400 mg/day for three days, followed by 200 mg/day for 11 days) or placebo (2 tablets for three days, followed by one tablet for 11 days). Main outcomes: The primary outcome is the number of PCR-confirmed infected pregnant women assessed from collected nasopharyngeal and oropharyngeal swabs at day 21 after treatment start (one week after treatment is completed). Randomisation: Allocation of participants to study arms will be done centrally by the trial's Sponsor (the Barcelona Institute for Global Health, ISGlobal) by block randomization. This method will ensure balanced allocation to both arms. The electronic CRF will automatically assign a study number to each participant, depending on her study group and recruitment site. Each number will be related to a treatment number, which assigns them to one of the study arms. Blinding (masking): Participants, caregivers, investigators and those assessing the outcomes will be blinded to group assignment. Study tablets (HCQ and placebo) will be identically packaged in small opaque bottles. Numbers to be randomised (sample size): This study requires 200 SARS-CoV-2 infected and 514 contact pregnant women, randomised 1:1 with 100 and 227 respectively in each study arm. Trial Status: Protocol version 1.0, from May 8th, 2020. Recruitment is ongoing (first patient recruited the 19th May 2020 and recruitment end anticipated by December 2020). Trial registration: EudraCT number: 2020-001587-29, registered 2 April 2020. Clinicaltrials.gov identifier: NCT04410562, retrospectively registered 1 June 2020.

    Serum micrornas as tool to predict early response to benralizumab in severe eosinophilic asthma

    Full text link
    Severe eosinophilic asthma poses a serious health and economic problem, so new therapy approaches have been developed to control it, including biological drugs such as benralizumab, which is a monoclonal antibody that binds to IL-5 receptor alpha subunit and depletes peripheral blood eosinophils rapidly. Biomarkers that predict the response to this drug are needed so that microRNAs (miRNAs) can be useful tools. This study was performed with fifteen severe eosinophilic asthmatic patients treated with benralizumab, and serum miRNAs were evaluated before and after treatment by semi-quantitative PCR (qPCR). Patients showed a clinical improvement after benralizumab administration. Additionally, deregulation of miR-1246, miR-5100 and miR-338-3p was observed in severe asthmatic patients after eight weeks of therapy, and a correlation was found between miR-1246 and eosinophil counts, including a number of exacerbations per year in these severe asthmatics. In silico pathway analysis revealed that these three miRNAs are regulators of the MAPK signaling pathway, regulating target genes implicated in asthma such as NFKB2, NFATC3, DUSP1, DUSP2, DUSP5 and DUSP16. In this study, we observed an altered expression of miR-1246, miR-5100 and miR-338-3p after eight weeks of benralizumab administration, which could be used as early response markers.This manuscript was funded by Fondo de Investigación Sanitaria–FIS and FEDER (Fondo Europeo de Desarrollo Regional) [PI15/00803, PI18/00044, and FI16/00036], CIBER de Enfermedades Respiratorias (CIBERES), Merck Health Foundation funds, and Ministerio de Ciencia, Innovación y Universidades (RTC-2017-6501-1

    Desde una concepción multidimensional de las expectativas, este artículo pretende analizar la validez y precisión psicométrica de una escala para su medida en los estudiantes universitarios de primer año. La muestra (N = 759) estaba compuesta por alumnado de primer año, de diversas titulaciones académicas de la Universidad de Vigo-Campus de Ourense y de la Universidad de Minho. El valor de la Mdn de edad fue de 19, siendo sólo el 5.3% mayor de 23 años. A los participantes se les aplicó un conjunto de 56 ítems agrupados en siete dimensiones diferentes de expectativas. Los resultados del análisis factorial confirmatorio, se obtuvieron con el LISREL. Se garantizó la validez factorial, tanto convergente como discriminante de los factores. Ésta junto con su fiabilidad sugieren que el Cuestionario de Percepciones Académicas quedaría finalmente con 42 ítems distribuidos en siete dimensiones de expectativas: Formación para el empleo/carrera, Desarrollo personal y social, Movilidad estudiantil, Implicación política/ciudadanía, Presión social, Calidad de formación e Interacción social. Se comprobó la equivalencia del modelo de medida del instrumento en los dos idiomas y en dos grupos resultantes de la bipartición aleatoria de la muestra. Los resultados de la validez estructural de este estudio avalan la utilización del cuestionario para la medida de las expectativas de los estudiantes que inician por primera vez sus estudios en la Enseñanza Superior.This paper aims to test the psychometric validity and reliability of a measure of first-year university students’ expectations, based on a multidimensional conception of expectations. The sample consisted of 759 first-year students, attending various academic degrees at the Universities of Vigo - Ourense and University of Minho. The value Mdn age was 19, with only 5.3% with ages above 23 years. Participants answered a set of 56 items based on seven different dimensions of expectations. Results of confirmatory factor analysis, were carried out with LISREL. Factorial validity, and factors’ convergent and discriminant validity were assured. These results, along with evidences reliability, suggest that the Academic Perceptions Questionnaire presents a final structure composed of seven expectation dimensions, including 42 items: Training for employment/career, Personal and social development, Student mobility, Political and citizenship involvement, Social pressure, Quality of education, and Social interaction. The equivalence of measurement model in the two languages and in two groups randomly derived from the full sample was also verified. The results of this structural validity study support the assessment of the expectations of first-year students in Higher Education with the questionnair

    This retrospective study investigated outcomes of 404 patients with relapsed/refractory (R/R) FMS-like tyrosine kinase 3 (FLT3)-internal tandem duplication (ITD) acute myeloid leukemia (AML) enrolled in the PETHEMA registry, pre-approval of tyrosine kinase inhibitors. Most patients (63%) had received first-line intensive therapy with 3 + 7. Subsequently, patients received salvage with intensive therapy (n = 261), non-intensive therapy (n = 63) or supportive care only (n = 80). Active salvage therapy (i.e., intensive or non-intensive therapy) resulted in a complete remission (CR) or CR without hematological recovery (CRi) rate of 42%. More patients achieved a CR/CRi with intensive (48%) compared with non-intensive (19%) salvage therapy (p < 0.001). In the overall population, median overall survival (OS) was 5.5 months; 1- and 5-year OS rates were 25% and 7%. OS was significantly (p < 0.001) prolonged with intensive or non-intensive salvage therapy compared with supportive therapy, and in those achieving CR/CRi versus no responders. Of 280 evaluable patients, 61 (22%) had an allogeneic stem-cell transplant after they had achieved CR/CRi. In conclusion, in this large cohort study, salvage treatment approaches for patients with FLT3-ITD mutated R/R AML were heterogeneous. Median OS was poor with both non-intensive and intensive salvage therapy, with best long-term outcomes obtained in patients who achieved CR/CRi and subsequently underwent allogeneic stem-cell transplant.This study was supported by Centro de Investigación Biomédica en Red Cáncer (CIBERONC), Valencia, Spain [CB16/12/00284]

    Impact of FLT3–ITD Mutation Status and Its Ratio in a Cohort of 2901 Patients Undergoing Upfront Intensive Chemotherapy: A PETHEMA Registry Study

    FLT3–ITD results in a poor prognosis in terms of overall survival (OS) and relapse-free survival (RFS) in acute myeloid leukemia (AML). However, the prognostic usefulness of the allelic ratio (AR) to select post-remission therapy remains controversial. Our study focuses on the prognostic impact of FLT3–ITD and its ratio in a series of 2901 adult patients treated intensively in the pre-FLT3 inhibitor era and reported in the PETHEMA registry. A total of 579 of these patients (20%) harbored FLT3–ITD mutations. In multivariate analyses, patients with an FLT3–ITD allele ratio (AR) of >0.5 showed a lower complete remission (CR rate) and OS (HR 1.47, p = 0.009), while AR > 0.8 was associated with poorer RFS (HR 2.1; p 0.5). Using the maximally selected log-rank statistics, we established an optimal cutoff of FLT3–ITD AR of 0.44 for OS, and 0.8 for RFS. We analyzed the OS and RFS according to FLT3–ITD status in all patients, and we found that the group of FLT3–ITD-positive patients with AR 0.44, allo-HSCT was superior to auto-HSCT in terms of OS and RFS. This study provides more evidence for a better characterization of patients with AML harboring FLT3–ITD mutations.This study was fundedby Instituto de Salud Carlos III (ISCIII) through the project PI19/01518 and PI19/00730 and co- funded by the European Union, the CRIS Against Cancer Foundation, grant 2018/001, and by the Instituto de Investigación Hospital 12 de Octubre (IMAS12).
