    In recent years, the cosplay practice has become a ubiquitous activity, representing a pivotal way to get in touch with the so-called geek culture and its media content (such as videogames, comics, manga). Cosplaying appeared related to narcissistic fragility which in turn is strictly linked to social appearance anxiety and self-objectification experiences. However, despite the body image centrality in cosplay practice, no studies evaluated cosplayers’ narcissistic vulnerability in association with these body imagerelated issues. A total of 926 young adults (73.2% female; 47.3% cosplayer; mean age=25.3 years) participated in the study. Results confirmed the direct and indirect effect of narcissistic vulnerability on social appearance anxiety (via body surveillance and body shame) among both cosplayers and noncosplayers. Overall, narcissistically vulnerable individuals, regardless of their involvement in cosplay practice, seem to experience higher body surveillance and body shame, which in turn might promote social appearance anxiety

    Background. This study’s primary aim was to evaluate the impact of thrombotic complications on the development of secondary infections. The secondary aim was to compare the etiology of secondary infections in patients with and without thrombotic complications. Methods. This was a cohort study (NCT04318366) of coronavirus disease 2019 (COVID-19) patients hospitalized at IRCCS San Raffaele Hospital between February 25 and June 30, 2020. Incidence rates (IRs) were calculated by univariable Poisson regression as the number of cases per 1000 person-days of follow-up (PDFU) with 95% confidence intervals. The cumulative incidence functions of secondary infections according to thrombotic complications were compared with Gray’s method accounting for competing risk of death. A multivariable Fine-Gray model was applied to assess factors associated with risk of secondary infections. Results. Overall, 109/904 patients had 176 secondary infections (IR, 10.0; 95% CI, 8.8–11.5; per 1000-PDFU). The IRs of secondary infections among patients with or without thrombotic complications were 15.0 (95% CI, 10.7–21.0) and 9.3 (95% CI, 7.9–11.0) per 1000-PDFU, respectively (P = .017). At multivariable analysis, thrombotic complications were associated with the development of secondary infections (subdistribution hazard ratio, 1.788; 95% CI, 1.018–3.140; P = .043). The etiology of secondary infections was similar in patients with and without thrombotic complications. Conclusions. In patients with COVID-19, thrombotic complications were associated with a high risk of secondary infections

    Background & Aims: Acute decompensation (AD) of cirrhosis may present without acute-on-chronic liver failure (ACLF) (ADNo ACLF), or with ACLF (AD-ACLF), defined by organ failure(s). Herein, we aimed to analyze and characterize the precipitants leading to both of these AD phenotypes. Methods: The multicenter, prospective, observational PREDICT study (NCT03056612) included 1,273 non-electively hospitalized patients with AD (No ACLF = 1,071; ACLF = 202). Medical history, clinical data and laboratory data were collected at enrolment and during 90-day follow-up, with particular attention given to the following characteristics of precipitants: induction of organ dysfunction or failure, systemic inflammation, chronology, intensity, and relationship to outcome. Results: Among various clinical events, 4 distinct events were precipitants consistently related to AD: proven bacterial infections, severe alcoholic hepatitis, gastrointestinal bleeding with shock and toxic encephalopathy. Among patients with precipitants in the AD-No ACLF cohort and the AD-ACLF cohort (38% and 71%, respectively), almost all (96% and 97%, respectively) showed proven bacterial infection and severe alcoholic hepatitis, either alone or in combination with other events. Survival was similar in patients with proven bacterial infections or severe alcoholic hepatitis in both AD phenotypes. The number of precipitants was associated with significantly increased 90day mortality and was paralleled by increasing levels of surrogates for systemic inflammation. Importantly, adequate first-line antibiotic treatment of proven bacterial infections was associated with a lower ACLF development rate and lower 90-day mortality. Conclusions: This study identified precipitants that are significantly associated with a distinct clinical course and prognosis in patients with AD. Specific preventive and therapeutic strategies targeting these events may improve outcomes in patients with decompensated cirrhosis. Lay summary: Acute decompensation (AD) of cirrhosis is characterized by a rapid deterioration in patient health. Herein, we aimed to analyze the precipitating events that cause AD in patients with cirrhosis. Proven bacterial infections and severe alcoholic hepatitis, either alone or in combination, accounted for almost all (96-97%) cases of AD and acute-on-chronic liver failure. Whilst the type of precipitant was not associated with mortality, the number of precipitant(s) was. This study identified precipitants that are significantly associated with a distinct clinical course and prognosis of patients with AD. Specific preventive and therapeutic strategies targeting these events may improve patient outcomes. (c) 2020 European Association for the Study of the Liver. Published by Elsevier B.V.

    Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

    Get PDF
    A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

    Informe final del escaneo de horizonte sobre futuras especies exóticas invasoras en España

    Get PDF
    73 p.La introducción de especies exóticas invasoras (EEI) es una de las principales causas de la pérdida de biodiversidad a nivel global, que provoca grandes costes socioeconómicos. Sin embargo, el número de nuevas introducciones continúa creciendo año tras año. Por lo tanto, urge identificar posibles futuras EEI con el objetivo de diseñar e implementar medidas que prevengan y mitiguen los efectos negativos de su introducción. Así, el objetivo de este estudio es prospectar qué especies exóticas no establecidas en España podrían llegar fácilmente en los próximos 10 años, establecerse y causar importantes impactos ecológicos. Para ello, se ha realizado un escaneo de horizonte, siguiendo la metodología establecida en trabajos previos, siendo el primero para el conjunto de las especies exóticas invasoras en España. Se añadieron en el análisis especies que no son autóctonas de España, incluyendo los archipiélagos de Canarias y Baleares, y que no están establecidas en España. Un total de 39 científicos, expertos en distintos grupos taxonómicos y ecosistemas, ha evaluado 933 especies. Con el objetivo de analizar el acuerdo entre las evaluaciones individuales de los expertos y su consistencia, se llevaron a cabo dos análisis de fiabilidad complementarios, cuyos resultados se discuten en este informe. Como resultado del escaneo, se obtuvo una lista priorizada de 105 especies (46 con riesgo muy alto y 59 con riesgo alto). La mayoría de estas especies (84,8%), sin embargo, no están incluidas actualmente en el Catálogo Español de Especies Exóticas Invasoras. Por lo tanto, se recomienda la realización de un análisis de riesgo más detallado de estas especies y, si se confirma el riesgo alto, la solicitud de su incorporación en dicho catálogo o en el Listado de especies alóctonas susceptibles de competir con las especies silvestres autóctonas, alterar su pureza genética o los equilibrios ecológicos. Del mismo modo, se propone la realización de escaneos de horizonte específicos para los archipiélagos de Canarias y Baleares, ya que muchas de las especies autóctonas de la Península no lo son de las islas y podrían tener un gran impacto si allí se introdujeran. Este informe también analiza la afinidad taxonómica (i.e. filo) y funcional (i.e. productor primario, depredador, omnívoro, herbívoro o filtrador) de las especies de la lista priorizada, su origen geográfico y las principales vías de introducción. Por último, discute los mecanismos de impacto de dichas especies.Ministerio de Ciencia e Innovació
