Prenatal ultrasound can often reliably distinguish fetal anatomic anomalies, particularly in the hands of an experienced ultrasonographer. Given the large number of existing syndromes and the significant overlap in prenatal findings, antenatal differentiation for syndrome diagnosis is difficult. We constructed a hierarchic tree of 1140 sonographic markers and submarkers, organized per organ system. Subsequently, a database of prenatally diagnosable syndromes was built. An internet-based search engine was then designed to search the syndrome database based on a single or multiple sonographic markers. Future developments will include a database with magnetic resonance imaging findings as well as further refinements in the search engine to allow prioritization based on incidence of syndromes and markers.

Aim To assess the geographical transferability of niche-based species distribution models fitted with two modelling techniques. Location Two distinct geographical study areas in Switzerland and Austria, in the subalpine and alpine belts. Methods Generalized linear and generalized additive models (GLM and GAM) with a binomial probability distribution and a logit link were fitted for 54 plant species, based on topoclimatic predictor variables. These models were then evaluated quantitatively and used for spatially explicit predictions within (internal evaluation and prediction) and between (external evaluation and prediction) the two regions. Comparisons of evaluations and spatial predictions between regions and models were conducted in order to test if species and methods meet the criteria of full transferability. By full transferability, we mean that: (1) the internal evaluation of models fitted in region A and B must be similar; (2) a model fitted in region A must at least retain a comparable external evaluation when projected into region B, and vice-versa; and (3) internal and external spatial predictions have to match within both regions. Results The measures of model fit are, on average, 24% higher for GAMs than for GLMs in both regions. However, the differences between internal and external evaluations (AUC coefficient) are also higher for GAMs than for GLMs (a difference of 30% for models fitted in Switzerland and 54% for models fitted in Austria). Transferability, as measured with the AUC evaluation, fails for 68% of the species in Switzerland and 55% in Austria for GLMs (respectively for 67% and 53% of the species for GAMs). For both GAMs and GLMs, the agreement between internal and external predictions is rather weak on average (Kulczynski's coefficient in the range 0.3-0.4), but varies widely among individual species. The dominant pattern is an asymmetrical transferability between the two study regions (a mean decrease of 20% for the AUC coefficient when the models are transferred from Switzerland and 13% when they are transferred from Austria). Main conclusions The large inter-specific variability observed among the 54 study species underlines the need to consider more than a few species to test properly the transferability of species distribution models. The pronounced asymmetry in transferability between the two study regions may be due to peculiarities of these regions, such as differences in the ranges of environmental predictors or the varied impact of land-use history, or to species-specific reasons like differential phenotypic plasticity, existence of ecotypes or varied dependence on biotic interactions that are not properly incorporated into niche-based models. The lower variation between internal and external evaluation of GLMs compared to GAMs further suggests that overfitting may reduce transferability. Overall, a limited geographical transferability calls for caution when projecting niche-based models for assessing the fate of species in future environments.

L’objectiu d’aquest article és presentar dues situacions diferents que es van produir a la Comunitat de Preveres de Sallent durant la segona meitat del segle XVIII i que permeten analitzar alguns aspectes del funcionament de les comunitats de preveres en general. En primer lloc, un conflicte intern produït per la pèrdua de rendes després de la reducció de 1750. En segon lloc, els problemes que es van generar entre la Comunitat i la població a causa d’unes pràctiques indignes d’alguns dels membres de la Comunitat. Finalment, els llevadors de comptes de March Sanmartí, que va ser col·lector entre 1775 i 1778, a partir dels quals analitzem les diferents procedències dels ingressos. L’elecció dels temes ha estat donada per la mateixa documentació. La parròquia de Sallent va perdre l’arxiu durant la Guerra Civil i, per tant, hem utilitzat el fons de l’Arxiu Episcopal de Vic i el fons de l’arxiu del mas Sanmartí, d’on era originari el col·lector.

Please cite this paper as: Maurer et al. (2012) Who knew? Awareness of being recommended for influenza vaccination among US adults. Influenza and Other Respiratory Viruses 6(4), 284-290. Background  Starting with the 2010-2011 influenza season, the Advisory Committee on Immunization Practices at the US Centers for Disease Control and Prevention recommends annual influenza vaccination to all people aged 6 months and older unless contraindicated. Objectives  To measure perceived influenza vaccination recommendation status among US adults (n = 2122) and its association with socio-demographic characteristics and recommendation status during the 2009-2010 pandemic influenza season. Methods  We analyze nationally representative data from longitudinal Internet surveys of US adults conducted in November-December 2009 and September-October 2010. Results  During the 2010-2011 vaccination season, 46·2 percent (95%-CI: 43·3-49·1%) of US adults correctly reported to be covered by a government recommendation for influenza vaccination. Awareness of being covered by a government influenza vaccination recommendation was statistically significantly higher among non-working adults and adults who had been recommended for seasonal vaccination or both seasonal and H1N1 vaccination during the 2009-2010 pandemic influenza vaccination season. Conclusion  Our results highlight that a majority of US adults do not know that they are recommended for annual influenza vaccination by the government. The fraction of adults who are unaware of their recommendation status is especially large among newly recommended healthy young adults. The universal vaccination recommendations will only be successful if they reach both patients and physicians and lead to changing vaccination practices. The universal nature of the new recommendation simplifies vaccination-related outreach and compliance with government vaccination guidelines considerably, as it does not require any identification of specific recommendation groups based on complex personal or health risk factors.

L’objectiu d’aquest projecte és estudiar la recepció de l’obra de Bach des de la seva vida fins l’actualitat. Es pretén, d’una banda, esbrinar quins són els motius que van produir que cada època històrica jutjés l’obra de Bach de diferent manera, quins van ser els mitjans de conservació de la seva obra així com quins canvis va patir la seva obra per tal d’encaixar amb cada època. D’altra banda pretén exemplificar aquesta diferència en la posició que cada època va atorgar a l’obra de Bach mitjançant obres de compositors posteriors (Mozart, Schumann, Brahms, Britten i Villa-Lobos) que, cadascuna de manera diferent, contenen alguna reminiscència de Bach. La metodologia utilitzada ha consistit en la seva major part en la recerca bibliogràfica però també en la comparació de versions d’obres musicals en partitures i gravacions. La conclusió principal que es pot extreure d’aquest treball és que cadascú és producte de la seva època amb el seu context particular i per tant, qualsevol interpretació que pugui fer d’una obra musical amb el seu estil compositiu ve fortament determinat per la ideologia del context que l’envolta. És normal, doncs, que el segle XVIII la decadència del pensament religiós comportés un rebuig per l’obra de Bach la qual és majoritàriament de caràcter religiós, mentre que el segle XIX amb l’emergència de la burgesia i els seus valors romàntics s’elevés la figura de Bach com l’heroi del poble alemany.
