    El creciente poder de los/las bloggers, youtubers, y cualquier otro tipo de líder de opinión, prescriptor o influencer surgido/a en cualquier plataforma social ha emergido en los últimos años como una nueva y valiosa forma de comunicación para las empresas. De hecho, las opiniones que los usuarios vierten en redes sociales se han convertido en parte del proceso de decisión de compra ya que generan electronic word-of-mouth muy fiable, creíble y ayudan a otros usuarios a reducir la incertidumbre y el riesgo ante una compra de un producto desconocido. El presente trabajo profundiza en el fenómeno de la comunicación entre consumidores (C2C) para lo que se propone analizar el contenido generado en plataformas sociales de video (YouTube) por influencers con el objetivo de analizar si existen diferencias significativas en términos de engagement entre el contenido patrocinado y el no patrocinado por marcas.The growing power of bloggers, youtubers, and any other type of opinion leader or influencer emerged from any social platform is considered nowadays as a valuable form of communication for companies. In fact, users-generated content in social networks has become part of the purchase decision process as they generate very reliable and credible electronic word-of-mouth. In addition, this content helps other users to reduce uncertainty and risk associated with a purchase of an unknown product. This research delves into the phenomenon of communication between consumers (C2C). For this task we propose to analyse the content generated in video social platforms (YouTube) by influencers with the objective of examining if there are significant differences in terms of engagement between contents sponsored by brands and contents non-sponsored by brands

    The association between psychopathic traits and conduct problems has been extensively analyzed, with results showing a significant predictive effect of psychopathic traits on later conduct problems. However, some recent research has evidenced some reversed effects, with early-onset conduct problems also showing a significant effect on psychopathic traits. The present study aimed to examine the longitudinal effects (i.e., autoregressive, direct, and bidirectional) between the three psychopathy dimensions (i.e., interpersonal, affective, and behavioral), and conduct problems in two data collections spanning one year (T1-T2). The potential mediation effect from inconsistent parenting and parental warmth was also analyzed. Data were collected, trough parents’ reports, in a sample of 1.833 children (48.8% girls; Mage = 4.24; SD = 0.92), participating in the ELISA study (Longitudinal Study for a Healthy Childhood). A cross-lagged path analysis with mediation effects was performed in Mplus. Results showed autoregressive, direct and bidirectional effects between psychopathic traits and conduct problems. Hence, whilst T1 conduct problems predicted all psychopathy dimensions in T2, only callous-unemotional and impulsive/need of stimulation traits measured in T1 predicted conduct problems in T2. Finally, some marginal mediation effects from inconsistent parenting and parental warmth were also observed, particularly in the relationship between interpersonal and affective psychopathic traits, and later CP through parental warmth. Current findings provide relevant implications for developmental models of psychopathic traits, as well as for predictive models and preventive strategies on early-onset conduct problemsLa relación entre rasgos psicopáticos y problemas de conducta ha sido extensamente analizada, constándose un efecto predictivo de los rasgos psicopáticos sobre los problemas de conducta a lo largo del desarrollo. Sin embargo, investigaciones recientes mostraron que los problemas de conducta de inicio temprano también pueden jugar un papel fundamental en el desarrollo de los rasgos de tipo psicopático. El presente trabajo tiene como objetivo principal analizar los efectos longitudinales (i.e., autorregresivos, directos y recíprocos) entre las tres dimensiones de la personalidad psicopática (interpersonal, afectiva y conductual) y los problemas de conducta a largo de un 1 año de estudio (T1-T2), analizando el posible efecto mediador de las prácticas parentales inconsistentes y basadas en el afecto. Se emplearon datos de 1.833 niños/as (48.8% niñas; edad media = 4.24; DT = 0.92), proporcionados a través de informes de padres, participantes en el proyecto ELISA (Estudio Longitudinal para una Infancia Saludable). Se realizó un diseño longitudinal en panel con efectos de mediación en Mplus. Los resultados mostraron efectos autorregresivos, directos y recíprocos entre problemas de conducta y rasgos psicopáticos. Así, mientras los problemas de conducta en T1 permiten predecir cambios en las tres dimensiones de psicopatía en T2, únicamente los rasgos de dureza emocional e impulsividad/búsqueda de sensaciones en T1, predicen cambios en problemas de conducta en T2. Por último, se evidenció el posible papel mediador de las prácticas parentales, particularmente en la relación entre rasgos psicopáticos de tipo interpersonal y afectivo, y los problemas de conducta a través de las prácticas basadas en el afecto. Los resultados obtenidos permiten extraer importantes implicaciones sobre los modelos de desarrollo de la personalidad psicopática, así como para la predicción y prevención de los problemas de conducta de inicio tempranoThis study was funded by FEDER/Ministerio de Ciencia, Innovación y Universidades – Agencia Estatal de Investigación/Grant (PSI2015-65766-R); Axudas para a Consolidación e Estruturación de Unidades de Investigación Competitivas e outras Accións de Fomento nas Univeridades; GRC, 2018 (Consellería de Cultura, Educación e Ordenación Universitaria, Xunta de Galicia); and Programa de Axudas á Etapa Posdoutoral da Xunta de Galicia (2017)/Programa de Axudas para Completar a Etapa de Formación Posdoutoral (2021) (Consellería de Cultura, Educación e Ordenación Universitaria, Xunta de Galicia)S

    Children Coping, Contextual Risk and Their Interplay During the COVID-19 Pandemic: A Spanish Case

    Get PDF
    The COVID-19 pandemic has changed the lives of millions of people around the globe and some of the unprecedent emerged disruptions, are likely to have been particularly challenging for young children (e.g., school closures, social distancing measures, movement restrictions). Studying the impact of such extraordinary circumstances on their well-being is crucial to identify processes leading to risk and resilience. To better understand how Spanish children have adapted to the stressful disruptions resulting from the pandemic outbreak, we examined the effects of child coping and its interactions with contextual stressors (pandemic and family related) on child adjustment, incorporating in our analysis a developmental perspective. Data was collected in April 2020, through parent-reports, during the acute phase of the pandemic and, temporarily coinciding with the mandatory national quarantine period imposed by the Spanish Government. A sample of 1,123 Spanish children (50% girls) aged 3 to 12 (Mage = 7.26; SD = 2.39) participated in the study. Results showed differences in the use of specific strategies by children in different age groups (i.e., 3–6, 7–9 and 10–12-year-olds). Despite the uncontrollable nature of the pandemic-related stressors, child disengagement coping was distinctively associated to negative outcomes (i.e., higher levels of behavioral and emotional difficulties), whereas engagement coping predicted psychosocial adjustment across all age groups. Moreover, interactively with child coping, parent fear of the future and parent dispositional resilience appear as relevant contextual factors to predict both negative and positive outcomes, but their effects seem to be age dependent, suggesting a higher contextual vulnerability for younger children. These findings might have implications for identifying individual and contextual risk and informing potential preventive interventions aimed to reduce the impact of future pandemic outbreaks on children of different agesFEDER/Ministerio de Ciencia, Innovación y Universidades – Agencia Estatal de Investigación/Grant (PSI2015-65766-R) and Axudas para a Consolidación e Estruturación de Unidades de Investigación Competitivas e outras Accións de Fomento nas Univeridades; GRC, 2018 (Consellería de Cultura, Educación e Ordenación Universitaria, Xunta de Galicia) provided finantial support for this research.

    Lipidomics as a Tool in the Diagnosis and Clinical Therapy

    Get PDF
    The lipids are essential compounds of cells, with biochemical and structural properties. Lipids are classified according to their chain length or saturation levels and biogenesis. Lipidomics is a spectroscopic and spectrometric technique, like Mass Spectrometry and Nuclear Magnetic Resonance, as well as bioinformatics to quantify and characterize the lipid profile. Lipidomics enables the fundamental understanding of lipid biology, the identification of drug targets for therapy, and the discovery of lipid biomarkers of disease cohorts. Therefore, lipidomics allows knowing the diagnosis and clinical follow-up in medical therapy towards any disease. In this way, the lipid profile allows us to monitor the administration of a clinical treatment and assertively diagnose human diseases

    BackgroundIbrexafungerp (SCY-078) is the newest oral and intravenous antifungal drug with broad activity, currently undergoing clinical trials for invasive candidiasis. ObjectiveThe aim of this study was to assess the in vitro activity of ibrexafungerp and comparators against a collection of 434 European blood isolates of Candida. MethodsIbrexafungerp, caspofungin, fluconazole, and micafungin minimum inhibitory concentrations (MICs) were collected from 12 European laboratories for 434 blood isolates, including 163 Candida albicans, 108 Candida parapsilosis, 60 Candida glabrata, 40 Candida tropicalis, 29 Candida krusei, 20 Candida orthopsilosis, 6 Candida guilliermondii, 2 Candida famata, 2 Candida lusitaniae, and 1 isolate each of Candida bracarensis, Candida catenulata, Candida dubliniensis, and Candida kefyr. MICs were determined by the EUCAST broth microdilution method, and isolates were classified according to recommended clinical breakpoints and epidemiological cutoffs. Additionally, 22 Candida auris from different clinical specimens were evaluated. ResultsIbrexafungerp MICs ranged from 0.016 to >= 8 mg/L. The lowest ibrexafungerp MICs were observed for C. albicans (geometric MIC 0.062 mg/L, MIC range 0.016-0.5 mg/L) and the highest ibrexafungerp MICs were observed for C. tropicalis (geometric MIC 0.517 mg/L, MIC range 0.06->= 8 mg/L). Modal MICs/MIC(50)s (mg/L) against Candida spp. were 0.125/0.06 for C. albicans, 0.5/0.5 for C. parapsilosis, 0.25/0.25 for C. glabrata, 0.5/0.5 for C. tropicalis, 1/1 for C. krusei, 4/2 for C. orthopsilosis, and 0.5/0.5 for C. auris. Ibrexafungerp showed activity against fluconazole- and echinocandin-resistant isolates. If adopting wild-type upper limits, a non-wild-type phenotype for ibrexafungerp was only observed for 16/434 (3.7%) isolates: 11 (4.6%) C. parapsilosis, 4 (5%) C. glabrata, and 1 (2.5%) C. tropicalis. ConclusionIbrexafungerp showed a potent in vitro activity against Candida.This study received funding from SCYNEXIS.

    HTLV-1 infection is a neglected disease, despite infecting 10-15 million people worldwide and severe illnesses develop in 10% of carriers lifelong. Acknowledging a greater risk for developing HTLV-1 associated illnesses due to immunosuppression, screening is being widely considered in the transplantation setting. Herein, we report the experience with universal HTLV testing of donors and recipients of solid organ transplants in a survey conducted in Spain. All hospitals belonging to the Spanish HTLV network were invited to participate in the study. Briefly, HTLV antibody screening was performed retrospectively in all specimens collected from solid organ donors and recipients attended since the year 2008. A total of 5751 individuals were tested for HTLV antibodies at 8 sites. Donors represented 2312 (42.2%), of whom 17 (0.3%) were living kidney donors. The remaining 3439 (59.8%) were recipients. Spaniards represented nearly 80%. Overall, 9 individuals (0.16%) were initially reactive for HTLV antibodies. Six were donors and 3 were recipients. Using confirmatory tests, HTLV-1 could be confirmed in only two donors, one Spaniard and another from Colombia. Both kidneys of the Spaniard were inadvertently transplanted. Subacute myelopathy developed within 1 year in one recipient. The second recipient seroconverted for HTLV-1 but the kidney had to be removed soon due to rejection. Immunosuppression was stopped and 3 years later the patient remains in dialysis but otherwise asymptomatic. The rate of HTLV-1 is low but not negligible in donors/recipients of solid organ transplants in Spain. Universal HTLV screening should be recommended in all donor and recipients of solid organ transplantation in Spain. Evidence is overwhelming for very high virus transmission and increased risk along with the rapid development of subacute myelopathy

    Identifying associations between diabetes and acute respiratory distress syndrome in patients with acute hypoxemic respiratory failure: an analysis of the LUNG SAFE database

    Background: Diabetes mellitus is a common co-existing disease in the critically ill. Diabetes mellitus may reduce the risk of acute respiratory distress syndrome (ARDS), but data from previous studies are conflicting. The objective of this study was to evaluate associations between pre-existing diabetes mellitus and ARDS in critically ill patients with acute hypoxemic respiratory failure (AHRF). Methods: An ancillary analysis of a global, multi-centre prospective observational study (LUNG SAFE) was undertaken. LUNG SAFE evaluated all patients admitted to an intensive care unit (ICU) over a 4-week period, that required mechanical ventilation and met AHRF criteria. Patients who had their AHRF fully explained by cardiac failure were excluded. Important clinical characteristics were included in a stepwise selection approach (forward and backward selection combined with a significance level of 0.05) to identify a set of independent variables associated with having ARDS at any time, developing ARDS (defined as ARDS occurring after day 2 from meeting AHRF criteria) and with hospital mortality. Furthermore, propensity score analysis was undertaken to account for the differences in baseline characteristics between patients with and without diabetes mellitus, and the association between diabetes mellitus and outcomes of interest was assessed on matched samples. Results: Of the 4107 patients with AHRF included in this study, 3022 (73.6%) patients fulfilled ARDS criteria at admission or developed ARDS during their ICU stay. Diabetes mellitus was a pre-existing co-morbidity in 913 patients (22.2% of patients with AHRF). In multivariable analysis, there was no association between diabetes mellitus and having ARDS (OR 0.93 (0.78-1.11); p = 0.39), developing ARDS late (OR 0.79 (0.54-1.15); p = 0.22), or hospital mortality in patients with ARDS (1.15 (0.93-1.42); p = 0.19). In a matched sample of patients, there was no association between diabetes mellitus and outcomes of interest. Conclusions: In a large, global observational study of patients with AHRF, no association was found between diabetes mellitus and having ARDS, developing ARDS, or outcomes from ARDS.

    Background: To better understand the epidemiology and patterns of tracheostomy practice for patients with acute respiratory distress syndrome (ARDS), we investigated the current usage of tracheostomy in patients with ARDS recruited into the Large Observational Study to Understand the Global Impact of Severe Acute Respiratory Failure (LUNG-SAFE) study. Methods: This is a secondary analysis of LUNG-SAFE, an international, multicenter, prospective cohort study of patients receiving invasive or noninvasive ventilation in 50 countries spanning 5 continents. The study was carried out over 4 weeks consecutively in the winter of 2014, and 459 ICUs participated. We evaluated the clinical characteristics, management and outcomes of patients that received tracheostomy, in the cohort of patients that developed ARDS on day 1-2 of acute hypoxemic respiratory failure, and in a subsequent propensity-matched cohort. Results: Of the 2377 patients with ARDS that fulfilled the inclusion criteria, 309 (13.0%) underwent tracheostomy during their ICU stay. Patients from high-income European countries (n = 198/1263) more frequently underwent tracheostomy compared to patients from non-European high-income countries (n = 63/649) or patients from middle-income countries (n = 48/465). Only 86/309 (27.8%) underwent tracheostomy on or before day 7, while the median timing of tracheostomy was 14 (Q1-Q3, 7-21) days after onset of ARDS. In the subsample matched by propensity score, ICU and hospital stay were longer in patients with tracheostomy. While patients with tracheostomy had the highest survival probability, there was no difference in 60-day or 90-day mortality in either the patient subgroup that survived for at least 5 days in ICU, or in the propensity-matched subsample. Conclusions: Most patients that receive tracheostomy do so after the first week of critical illness. Tracheostomy may prolong patient survival but does not reduce 60-day or 90-day mortality.

    Hyperoxemia and excess oxygen use in early acute respiratory distress syndrome : Insights from the LUNG SAFE study

    Get PDF
    Publisher Copyright: © 2020 The Author(s). Copyright: Copyright 2020 Elsevier B.V., All rights reserved.Background: Concerns exist regarding the prevalence and impact of unnecessary oxygen use in patients with acute respiratory distress syndrome (ARDS). We examined this issue in patients with ARDS enrolled in the Large observational study to UNderstand the Global impact of Severe Acute respiratory FailurE (LUNG SAFE) study. Methods: In this secondary analysis of the LUNG SAFE study, we wished to determine the prevalence and the outcomes associated with hyperoxemia on day 1, sustained hyperoxemia, and excessive oxygen use in patients with early ARDS. Patients who fulfilled criteria of ARDS on day 1 and day 2 of acute hypoxemic respiratory failure were categorized based on the presence of hyperoxemia (PaO2 > 100 mmHg) on day 1, sustained (i.e., present on day 1 and day 2) hyperoxemia, or excessive oxygen use (FIO2 ≥ 0.60 during hyperoxemia). Results: Of 2005 patients that met the inclusion criteria, 131 (6.5%) were hypoxemic (PaO2 < 55 mmHg), 607 (30%) had hyperoxemia on day 1, and 250 (12%) had sustained hyperoxemia. Excess FIO2 use occurred in 400 (66%) out of 607 patients with hyperoxemia. Excess FIO2 use decreased from day 1 to day 2 of ARDS, with most hyperoxemic patients on day 2 receiving relatively low FIO2. Multivariate analyses found no independent relationship between day 1 hyperoxemia, sustained hyperoxemia, or excess FIO2 use and adverse clinical outcomes. Mortality was 42% in patients with excess FIO2 use, compared to 39% in a propensity-matched sample of normoxemic (PaO2 55-100 mmHg) patients (P = 0.47). Conclusions: Hyperoxemia and excess oxygen use are both prevalent in early ARDS but are most often non-sustained. No relationship was found between hyperoxemia or excessive oxygen use and patient outcome in this cohort.
