13Are you suffering from a large arterial occlusion?Please raise your arm!显示文摘Background and purpose Triage tools to identify candidates for thrombectomy are of utmost importance in acute stroke.No prognostic tool has yet gained any widespread use.We compared the predictive value of various models based on National Institutes of Health Stroke Scale(NIHSS)subitems,ranging from simple to more complex models,for predicting large artery occlusion(LAO)in anterior circulation stroke.Methods Patients registered in the SITS international Stroke Register with available NIHSS and radiological arterial occlusion data were analysed.We compared 2042 patients harbouring an LAO with 2881 patients having no/distal occlusions.Using binary logistic regression,we developed models ranging from simple 1 NIHSS-subitem to full NIHSS-subitems models.Sensitivities and specificities of the models for predicting LAO were examined.results The model with highest predictive value included all NIHSS subitems for predicting LAO(area under the curve(AUC)0.77),yielding a sensitivity and specificity of 69%and 76%,respectively.The second most predictive model(AUC 0.76)included 4-NIHSS-subitems(level of consciousness commands,gaze,facial and arm motor function)yielding a sensitivity and specificity of 67%and 75%,respectively.The simplest model included only deficits in arm motor-function(AUC 0.72)for predicting LAO,yielding a sensitivity and specificity of 67%and 72%,respectively.Conclusions Although increasingly more complex models yield a higher discriminative performance for predicting LAO,differences between models are not large.Assessing grade of arm dysfunction along with an established stroke-diagnosis model may serve as a surrogate measure of arterial occlusion-status,thereby assisting in triage decisions.Charith Cooray Michael V Mazya Matteo Bottai Jan F Scheitz Azmil H Abdul-Rahim Tiago Prazeres Moreira Robert Mikulik Antonin Krajina Miroslava Nevsimalova Danilo Toni Nils Wahlgren Niaz Ahmed 2018Stroke & Vascular Neurology2018,3,4:0
14Current and historical factors drive variation of reproductive traits in unisexual mosses in Europe:A case study显示文摘Unisexual bryophytes provide excellent models to study the mechanisms that regulate the frequency of sexual versus asexual reproduction in plants,and their ecological and evolutionary implications.Here,we determined sex expression,phenotypic sex ratio,and individual shoot traits in 242 populations of the cosmopolitan moss Pseudoscleropodium purum spanning its whole distributional range.We tested whether niche differentiation,sex-specific differences in shoot size,and biogeographical history explained the spatial variation of reproductive traits.We observed high levels of sex expression and predominantly female-biased populations,although both traits showed high intraspecific variation among populations.Sex expression and sex ratio were partly explained by current macroscale environmental variation,with male shoots being less frequent at the higher end of the environmental gradients defined by the current distribution of the species.Female bias in population sex ratio was significantly lower in areas recolonized after the last glacial maximum(recent populations)than in glacial refugia(long-term persistent populations).We demonstrated that reproductive trait variation in perennial unisexual mosses is partially driven by macroscale and historical environmental variation.Based on our results,we hypothesize that sexual dimorphism in environmental tolerance and vegetative growth contribute to sex ratio bias over time,constraining the chances of sexual reproduction,especially in long-term persistent populations.Further studies combining genetic analyses and population monitoring should improve our understanding of the implications of the intraspecific variation in the frequency of sexual versus asexual reproduction in bryophyte population fitness and eco-evolutionary dynamics.María Teresa Boquete Zulema Varela JoséAngel Fernández Juan Antonio Calleja Cristina Branquinho Antonina Chilà Nils Cronberg Ricardo Cruz de Carvalho Cristiana Aleixo Belén Estébanez-Pérez Verónica Fernández-González Andrés Baselga Carola Gómez-Rodríguez Juana María González-Mancebo Sebastien Leblond Javier Martínez-Abaigar Nagore G.Medina Encarnación Núñez-Olivera Jairo Patiño Rubén Retuerto Antón Vázquez-Arias Alain Vanderpoorten Harald G.Zechmeister Jesús Ramón Aboal 2023Journal of Systematics and Evolution2023,61,1:0
