    Grapheme-color synesthetes experience graphemes as having a consistent color (e.g., “N is turquoise”). Synesthetes’ specific associations (which letter is which color) are often influenced by linguistic properties such as phonetic similarity, color terms (“Y is yellow”), and semantic associations (“D is for dog and dogs are brown”). However, most studies of synesthesia use only English-speaking synesthetes. Here, we measure the effect of color terms, semantic associations, and non-linguistic shape-color associations on synesthetic associations in Dutch, English, Greek, Japanese, Korean, Russian, and Spanish. The effect size of linguistic influences (color terms, semantic associations) differed significantly between languages. In contrast, the effect size of nonlinguistic influences (shape-color associations), which we predicted to be universal, indeed did not differ between languages. We conclude that language matters (outcomes are influenced by the synesthete’s language) and that synesthesia offers an exceptional opportunity to study influences on letter representations in different languages.Depto. de Psicobiología y Metodología en Ciencias del ComportamientoFac. de PsicologíaTRUEpu

    Neutralizing antibodies against the preactive form of respiratory syncytial virus fusion protein offer unique possibilities for clinical intervention

    Human respiratory syncytial virus (hRSV) is the most important viral agent of pediatric respiratory infections worldwide. The only specific treatment available today is a humanized monoclonal antibody (Palivizumab) directed against the F glycoprotein, administered prophylactically to children at very high risk of severe hRSV infections. Palivizumab, as most anti-F antibodies so far described, recognizes an epitope that is shared by the two conformations in which hRSV_F can fold, the metastable prefusion form and the highly stable postfusion conformation. We now describe a unique class of antibodies specific for the prefusion form of this protein that account for most of the neutralizing activity of either a rabbit serum raised against a vaccinia virus recombinant expressing hRSV_F or a human Ig preparation (Respigam), which was used for prophylaxis before Palivizumab. These antibodies therefore offer unique possibilities for immune intervention against hRSV, and their production should be assessed in trials of hRSV vaccines

    BACKGROUND: Colonization of large part of Europe by the Asian tiger mosquito Aedes albopictus is causing autochthonous transmission of chikungunya and dengue exotic arboviruses. While pyrethroids are recommended only to reduce/limit transmission, they are widely implemented to reduce biting nuisance and to control agricultural pests, increasing the risk of insurgence of resistance mechanisms. Worryingly, pyrethroid resistance (with mortality < 70%) was recently reported in Ae. albopictus populations from Italy and Spain and associated with the V1016G point mutation in the voltage-sensitive sodium channel gene conferring knockdown resistance (kdr). Genotyping pyrethroid resistance-associated kdr mutations in field mosquito samples represents a powerful approach to detect early signs of resistance without the need for carrying out phenotypic bioassays which require availability of live mosquitoes, dedicated facilities and appropriate expertise. METHODS: Here we report results on the PCR-genotyping of the V1016G mutation in 2530 Ae. albopictus specimens from 69 sampling sites in 19 European countries. RESULTS: The mutation was identified in 12 sites from nine countries (with allele frequencies ranging from 1 to 8%), mostly distributed in two geographical clusters. The western cluster includes Mediterranean coastal sites from Italy, France and Malta as well as single sites from both Spain and Switzerland. The eastern cluster includes sites on both sides of the Black Sea in Bulgaria, Turkey and Georgia as well as one site from Romania. These results are consistent with genomic data showing high connectivity and close genetic relationship among West European populations and a major barrier to gene flow between West European and Balkan populations. CONCLUSIONS: The results of this first effort to map kdr mutations in Ae. albopictus on a continental scale show a widespread presence of the V1016G allele in Europe, although at lower frequencies than those previously reported from Italy. This represents a wake-up call for mosquito surveillance programs in Europe to include PCR-genotyping of pyrethroid resistance alleles, as well as phenotypic resistance assessments, in their routine activities

    Outcomes of nonagenarians after transcatheter aortic valve implantation

    Introduction and objectives: Nonagenarians are a fast-growing age group among cardiovascular patients, especially with aortic stenosis, but data about their prognosis after transcatheter aortic valve implantation (TAVI) is scarce. The objective of our study is to analyze the baseline characteristics of nonagenarians treated with TAVI and determine whether age = 90 years is associated with a worse prognosis compared to non-nonagenarian patients. Methods: We included all patients =75 years enrolled in the multicenter prospective Spanish TAVI registry between 2009 and 2018. Patients < 75 years were excluded. Results: A total of 8073 elderly patients (= 75 years) from 46 Spanish centers were enrolled in the Spanish TAVI registry; 7686 were between = 75 and < 90 years old (95.2%), and 387 were nonagenarian patients (4.79%). A gradual increase of nonagenarians was observed. The transfemoral access was used in 91.6% of the cases, predominantly among the nonagenarian patients (91.4% vs 95.1%, P = .01). Nonagenarians were more likely to die during their hospital stay (4.3% vs 7.0% among nonagenarians, P = .01). However, no difference was seen in the all-cause mortality rates reported at the 1-year follow-up (8.8% vs 11.3%, P =.07). In the multivariate analysis, age = 90 years was not independently associated with a higher adjusted all-cause mortality rate (HR, 1.37, 95%CI, 0.91–1.97, P = .14). The baseline creatinine levels, and the in-hospital bleeding complications were all associated with a worse long-term prognosis in nonagenarians treated with TAVI. Conclusions: Nonagenarians are a very high-risk and growing population with severe AS in whom TAVI may be a safe and effective strategy. Careful patient selection by the TAVI heart team is mandatory to achieve maximum efficiency in this population where the baseline kidney function and bleeding complications may determine the long-term prognosis after TAVI. © 2021 Sociedad Española de Cardiología.
