Results of heart retransplantation: subanalysis of the Spanish Heart Transplant Registry

2021

Heart retransplantation (ReHT) is controversial in the current era. The aim of this study was to describe and analyze the results of ReHT in Spain. Methods We performed a retrospective cohort analysis from the Spanish Heart Transplant Registry from 1984 to 2018. Data were collected on donors, recipients, surgical procedure characteristics, immunosuppression, and survival. The main outcome was posttransplant all-cause mortality or need for ReHT. We studied differences in survival according to indication for ReHT, the time interval between transplants and era of ReHT. Results A total of 7592 heart transplants (HT) and 173 (2.3%) ReHT were studied (median age, 52.0 and 55.0 years, respectively…

Input vs. intake in formative assessment and explicit grammar teaching Do the students understand what we are talking about?

2020

The relevance of explicit grammar instruction in foreign language classrooms has been discussed widely in the past, but there is no consensus regarding what is the best approach or how much time should be spent on explicit grammar teaching. This paper presents the results of three studies which focus on students’ knowledge of explicit grammar, their understanding of metalinguistic terminology, and their ability to correct agreement errors in their texts as a response to formative assessment. In the first study, the effect of different types of formative feedback on the improvement in agreement marking accuracy was tested. As there were no statistically significant differences found, two fol…

Dominance of wine Saccharomyces cerevisiae strains over S. kudriavzevii in industrial fermentation competitions is related to an acceleration of nutr…

2019

Grape must is a sugar‐rich habitat for a complex microbiota which is replaced by Saccharomyces cerevisiae strains during the first fermentation stages. Interest on yeast competitive interactions has recently been propelled due to the use of alternative yeasts in the wine industry to respond to new market demands. The main issue resides in the persistence of these yeasts due to the specific competitive activity of S. cerevisiae. To gather deeper knowledge of the molecular mechanisms involved, we performed a comparative transcriptomic analysis during fermentation carried out by a wine S. cerevisiae strain and a strain representative of the cryophilic S. kudriavzevii, which exhibits high genet…

Interplay among Gcn5, Sch9 and mitochondria during chronological aging of wine yeast is dependent on growth conditions.

2015

Saccharomyces cerevisiae chronological life span (CLS) is determined by a wide variety of environmental and genetic factors. Nutrient limitation without malnutrition, i.e. dietary restriction, expands CLS through the control of nutrient signaling pathways, of which TOR/Sch9 has proven to be the most relevant, particularly under nitrogen deprivation. The use of prototrophic wine yeast allows a better understanding of the role of nitrogen in longevity in natural and more demanding environments, such as grape juice fermentation. We previously showed that acetyltransferase Gcn5, a member of the SAGA complex, has opposite effects on CLS under laboratory and winemaking conditions, and is detrimen…

Limits on neutral Higgs boson production in the forward region in $pp$ collisions at $\sqrt{s} = 7$ TeV

2013

Limits on the cross-section times branching fraction for neutral Higgs bosons, produced in p p collisions at root s = 7 TeV, and decaying to two tau leptons with pseudorapidities between 2.0 and 4.5, are presented. The result is based on a dataset, corresponding to an integrated luminosity of 1.0 fb(-1), collected with the LHCb detector. Candidates are identified by reconstructing final states with two muons, a muon and an electron, a muon and a hadron, or an electron and a hadron. A model independent upper limit at the 95% confidence level is set on a neutral Higgs boson cross-section times branching fraction. It varies from 8.6 pb for a Higgs boson mass of 90 GeV to 0.7 pb for a Higgs bos…

Doubling Recruitment of Pediatric Low-grade Glioma within Two Decades does not change Outcome – Report from the German LGG Studies

2021

Successive multicenter studies for pediatric low-grade glioma (LGG) in Germany were accompanied by a doubling of annual recruitment over 2 decades. We investigated whether this increase conveyed a change of epidemiologic characteristics or survival.Participating centers reported 4634 patients with the radiologic/histologic diagnosis of LGG (1996-2018), rising from 109 to 278/year. Relating these numbers to all pediatric CNS tumors registered at the German Childhood Cancer Registry, the LGG fraction and annual crude incidence rates increased (32% to 51%; 0.94 to 2.12/100,000 children/adolescents15 years). The consecutive LGG studies recruited 899 (HIT-LGG 1996), 1592 (SIOP-LGG 2004), and 183…

La communication : en long, en large mais surtout en travers

2016

International audience; Dans le cycle de conférences autour de « la communication, un enjeu citoyen », ma démarche est sans doute particulière puisqu'elle vise tout particulièrement l'enseignement de la communication. Et pourtant, il nous semble que cet enseignement participe pleinement à la notion de citoyen responsable. Une communication sur la communication. Voilà ce que le titre évoque. Mais si le titre de ce texte fait place à la communication, il se veut équivoque. En effet, l'expression « en travers » prête à commentaire. Aussi, précisons que celle-ci désigne la transversalité de la discipline et de son enseignement. Communication ! Le mot à lui tout seul laisse rêveur, tant il est u…

Are local food chains more sustainable than global food chains? Considerations for assessment

2016

© 2016 by the authors; licensee MDPI, Basel, Switzerland. This paper summarizes the main findings of the GLAMUR project which starts with an apparently simple question: is "local" more sustainable than "global"? Sustainability assessment is framed within a post-normal science perspective, advocating the integration of public deliberation and scientific research. The assessment spans 39 local, intermediate and global supply chain case studies across different commodities and countries. Assessment criteria cover environmental, economic, social, health and ethical sustainability dimensions. A closer view of the food system demonstrates a highly dynamic local-global continuum where actors, whil…
