Mortality from cardiovascular and cerebrovascular diseases in Europe and other areas of the world: an update.

OBJECTIVE: To update trends in mortality from coronary heart diseases (CHD) and cerebrovascular diseases (CVD) over the period 1981-2004 in Europe, the USA, Latin America, Japan and other selected areas of the world. METHODS: Age-standardized mortality rates were derived from the World Health Organization database. Joinpoint analysis was used to identify significant changes in trends. RESULTS: In the European Union (27 countries), CHD mortality in men declined from 139/100,000 in 1985-1989 to 93/100,000 in 2000-2004 (-33%). In women, the fall was from 61/100,000 to 44/100,000 (-27%). In this area, a decline by over 30% was also registered in CVD mortality for both sexes. In the Russian Federation and other countries of the former Soviet Union, CHD rates in 2000-2004 were exceedingly high, around 380/100,000 men and 170/100,000 women in Russia, 430 for men and 240 for women in Ukraine, 420 and 200 in Belarus. For CVD, a similar situation was registered, with mortality rates of 226/100,000 for men and 159/100,000 for women in 2004 in the Russian Federation, and more than 24% increase since the late 1980s for men and 15% for women. CHD and CVD mortality continued to decline in most Latin American countries, Australia and other areas considered, including Asia (even if with marked differences). CONCLUSION: Although mortality from CHD and CVD continues to decline in several areas of the world including most countries of Europe and of the America providing data and Australia, unfavourable trends were still observed in the Russian Federation and other countries of the former Soviet Union, whose recent rates remain exceedingly high.

La revolución energética cubana en la UCLV: ¿un paso en el camino hacia la sostenibilidad?. Parte II: Análisis de los impactos sociales

La Revolución Energética Cubana (REC) surge de las necesidades de resolver la situación social y económica de Cuba, sumergida en una crisis energética con constantes apagones que limitaban por completo el desarrollo del país. La REC (2006) es un conjunto de medidas basadas en los principios de la autosuficiencia energética, el ahorro y uso racional de la energía, y el incremento de la eficiencia en todos los aspectos. En el presente trabajo se realiza el análisis de la sostenibilidad socio-ambiental de la REC en la Universidad Central Marta Abreu de las Villas (UCLV), ubicada en Santa Clara (Cuba). La valoración se ha efectuado mediante el análisis de los impactos ambientales y sociales en dos estudios paralelos que se complementan aplicando la técnica de conmensurabilidad débil. El conjunto de los programas de la REC han propiciado mejoras en el suministro eléctrico y en el ahorro energético, disminuyendo en un 30% las emisiones de CO2, a pesar del incremento en la actividad docente y en la flota de equipos, en la universidad. Las medidas adoptadas han incidido en la calidad de la docencia, las condiciones de vida, la concienciación y la participación de la población, dando lugar a un impacto social positivo. De esta manera, el balance global de la REC se califica de positivo ya que ha permitido el desarrollo de la UCLV sin incrementar los impactos ambientales, por lo que se puede considerar un paso en el camino hacia la sostenibilidad socio-ambiental.

Marges i biodiversitat a Vandellòs i l'Hospitalet de l'Infant

Els marges de pedra seca són un dels ambients socioecològics més singulars del país i, al mateix temps, un dels hàbitats menys estudiats. La nostra recerca ha analitzat la biodiversitat de les margenades de Vandellòs i l’Hospitalet de l’Infant; mitjançant mostrejos de flora i de la fauna hem constatat l’elevada complexitat de la xarxa tròfica que s’estableix en aquest nínxol ecològic. En la vessant socioambiental, hem realitzat entrevistes a diferents entesos en la cultura de la pedra seca, les quals han permès determinar la importància dels marges per entendre una part de la història ambiental del país. Amb la recerca s’ha observat un clar retrocés del patrimoni de pedra seca a causa de la recessió del sector agrícola. L’aprofitament turístic de la cultura de la pedra seca i la implicació de les Administracions Públiques en la difusió d’aquest patrimoni, són claus per garantir-ne la pervivència en el futur.

Emotional intelligence: On definitions, neuroscience, and marshmallows

In his timely article, Cherniss offers his vision for the future of "Emotional Intelligence" (EI). However, his goal of clarifying the concept by distinguishing definitions from models and his support for "Emotional and Social Competence" (ESC) models will, in our opinion, not make the field advance. To be upfront, we agree that emotions are important for effective decision-making, leadership, performance and the like; however, at this time, EI and ESC have not yet demonstrated incremental validity over and above IQ and personality tests in meta-analyses (Harms & Credé, 2009; Van Rooy & Viswesvaran, 2004). If there is a future for EI, we see it in the ability model of Mayer, Salovey and associates (e.g, Mayer, Caruso, & Salovey, 2000), which detractors and supporters agree holds the most promise (Antonakis, Ashkanasy, & Dasborough, 2009; Zeidner, Roberts, & Matthews, 2008). With their use of quasi-objective scoring measures, the ability model grounds EI in existing frameworks of intelligence, thus differentiating itself from ESC models and their self-rated trait inventories. In fact, we do not see the value of ESC models: They overlap too much with current personality models to offer anything new for science and practice (Zeidner, et al., 2008). In this commentary we raise three concerns we have with Cherniss's suggestions for ESC models: (1) there are important conceptual problems in both the definition of ESC and the distinction of ESC from EI; (2) Cherniss's interpretation of neuroscience findings as supporting the constructs of EI and ESC is outdated, and (3) his interpretation of the famous marshmallow experiment as indicating the existence of ESCs is flawed. Building on the promise of ability models, we conclude by providing suggestions to improve research in EI.

The worldwide expansion of the Argentine ant

Aim The aim of this study was to determine the number of successful establishments of the invasive Argentine ant outside native range and to see whether introduced supercolonies have resulted from single or multiple introductions. We also compared the genetic diversity of native versus introduced supercolonies to assess the size of the propagules (i.e. the number of founding individuals) at the origin of the introduced supercolonies. Location Global. Methods We used mitochondrial DNA (mtDNA) markers and microsatellite loci to study 39 supercolonies of the Argentine ant Linepithema humile covering both the native (n = 25) and introduced range (n = 14). Results Data from three mitochondrial genes and 13 nuclear microsatellites suggest that the introduced supercolonies studied originated from at least seven founding events out of the native area in Argentina (primary introductions). The distribution of mtDNA haplotypes also suggests that supercolonies in the introduced range each derive from a single source supercolony and that one of these source supercolonies has been particularly successful, being the basis of many introduced populations spread across the world. Comparison of the genetic diversity of supercolonies based on the five most diverse loci also revealed that native and introduced supercolonies have greatly overlapping ranges of diversity, although the genetic diversity is on average less in introduced than in native supercolonies. Main conclusions Both primary introductions (from the native range) and secondary introductions (from sites with established invasive supercolonies) were important in the global expansion of the Argentine ant. In combination with the similar social organization of colonies in the native and introduced range, this indicates that invasiveness did not evolve recently as a unique and historically contingent event (e.g. reduction of genetic diversity) in this species. Rather, native L. humile supercolonies have characteristics that make them pre-adapted to invade new - and in particular disturbed - habitats when given the opportunity. These results have important implications with regard to possible strategies to be used to control invasive ants.

Capillaria hepatica: a cause of septal fibrosis of the liver

Fine, long, fibrous septa were observed as a late change developing in the acinar zone III of the liver of rats experimentally infected with the helminth Capillaria hepatica. Hepatic septal fibrosis begun 30 days after inoculation of embryonated eggs into the stomach of rats and became clearly evident from the 40th day onwards. Experimental observation was undertaken for 170 days. Septal fibrosis increased progressively with time and was most marked when the parasitic nodules formed around larvae, disintegrating worms and eggs were involving. Septal fibrosis of the liver has not been previously recognized as a manifestation of hepatic capillariasis. The presence of sequestered parasite antigens, probably being slowly released within the liver, appears to be a major factor in the pathogenesis of hepatic septal fibrosis observed in rats with C. hepatica infection.

Conflictes no, gràcies!: programa d’educació emocional en el Centre Penitenciari de Ponent

En la recerca s’expliquen els resultats de la implementació d’un programa adreçat bàsicament al treball de la consciència emocional de l’intern penitenciari i la regulació d’aquesta consciència. El motiu és que en el plantejament teòric es parteix de les constatacions de molts autors que els programes que millor funcionen en la rehabilitació i tractament del delinqüent ingressat a presó són aquells que tenen en compte no només l’ambient del delinqüent, la seva família, la seva educació escolar i formativa a nivell laboral sinó també l’estudi del seus sentiments i de manera clau la seva cognició, el seu raonament, la seva comprensió i també els seus valors.És per això que els programes eficaços semblen ser aquells que inclouen tècniques adreçades a millorar les habilitats de raonament, la empatia, l’avaluació de les conseqüències de la seva conducta envers els altres i sobre ells mateixos, la reflexió abans de l’acció, les seves habilitats per a la resolució de problemes i també en moltes ocasions les pròpies habilitats socials poc desenvolupades. Els resultats obtinguts analitzen les dades referents a l’impacte de la intervenció envers els interns i de manera específica envers la seva conducta.

Suivi de l'adhésion thérapeutique des patients hypertendus ou dyslipi- démiques par les cercles de qualité médecins-pharmaciens [Monitoring drug adherence for hypertensive and dyslipidemic patients in networks of community-based pharmacists and physicians].

Patient adherence is often poor for hypertension and dyslipidaemia. A monitoring of drug adherence might improve these risk factors control, but little is known in ambulatory care. We conducted a randomised controlled study in networks of community-based pharmacists and physicians in the canton of Fribourg to examine whether monitoring drug adherence with an electronic monitor (MEMS) would improve risk factor control among treated, but uncontrolled hypertensive and dyslipidemic patients. The results indicate that MEMS achieve a better blood pressure control and lipid profile, although its implementation requires considerable resources. The study also shows the value of collaboration between physicians and pharmacists in the field of patient adherence to improve ambulatory care of patients with cardiovascular risk factors.

Functional mapping of the human visual cortex with intravoxel incoherent motion MRI.

Functional imaging with intravoxel incoherent motion (IVIM) magnetic resonance imaging (MRI) is demonstrated. Images were acquired at 3 Tesla using a standard Stejskal-Tanner diffusion-weighted echo-planar imaging sequence with multiple b-values. Cerebro-spinal fluid signal, which is highly incoherent, was suppressed with an inversion recovery preparation pulse. IVIM microvascular perfusion parameters were calculated according to a two-compartment (vascular and non-vascular) diffusion model. The results obtained in 8 healthy human volunteers during visual stimulation are presented. The IVIM blood flow related parameter fD* increased 170% during stimulation in the visual cortex, and 70% in the underlying white matter.

IRF6 Screening of Syndromic and a priori Non-Syndromic Cleft Lip and Palate Patients: Identification of a New Type of Minor VWS Sign.

Van der Woude syndrome (VWS), caused by dominant IRF6 mutation, is the most common cleft syndrome. In 15% of the patients, lip pits are absent and the phenotype mimics isolated clefts. Therefore, we hypothesized that some of the families classified as having non-syndromic inherited cleft lip and palate could have an IRF6 mutation. We screened in total 170 patients with cleft lip with or without cleft palate (CL/P): 75 were syndromic and 95 were a priori part of multiplex non-syndromic families. A mutation was identified in 62.7 and 3.3% of the patients, respectively. In one of the 95 a priori non-syndromic families with an autosomal dominant inheritance (family B), new insights into the family history revealed the presence, at birth, of lower lip pits in two members and the diagnosis was revised as VWS. A novel lower lip sign was observed in one individual in this family. Interestingly, a similar lower lip sign was also observed in one individual from a 2nd family (family A). This consists of 2 nodules below the lower lip on the external side. In a 3rd multiplex family (family C), a de novo mutation was identified in an a priori non-syndromic CL/P patient. Re-examination after mutation screening revealed the presence of a tiny pit-looking lesion on the inner side of the lower lip leading to a revised diagnosis of VWS. On the basis of this data, we conclude that IRF6 should be screened when any doubt rises about the normality of the lower lip and also if a non-syndromic cleft lip patient (with or without cleft palate) has a family history suggestive of autosomal dominant inheritance.

La presa de consciència de les actituds a l'educació física en la formació inicial de mestres de primària

Aquest treball és el resultat d’un procés de reflexió al voltant de les actituds dins la Formació Inicial de mestres de primària d’Educació física. Es tracta, d’una primera aproximació d’anàlisi i interpretació sobre la presa de consciència d’actituds que fan els estudiants en la pràctica de l’Educació física. Les preguntes que em plantejo en aquesta recerca són el resultat de les dues parts que configura aquest treball. La primera pregunta, es centra en el marc teòric de l’estudi, donant resposta a les relacions que s’estableixen entre l’educació física i l’educació en valors en el currículum de primària d’Educació física i en la Formació Inicial de mestres. La segona pregunta, pretén donar resposta a la proposta pràctica i així, esbrinar el paper del joc motor en el treball educatiu de les actituds en la Formació Inicial de mestres de primària. Els aspectes teòrics que estudio analitzen la relació que s’estableix entre l’Educació física i les actituds dins el marc educatiu de la Formació Inicial de mestres de primària. I serà, a partir de la proposta pràctica quan el joc motor esdevindrà element d’aproximació en la presa de consciència d’actituds En el context de la Facultat d’Educació de la Universitat de Vic, i en l’assignatura d’Educació física i la seva Didàctica de 2n curs, els estudiants de mestres de primària d’Educació física són protagonistes del seu propi procés d’aprenentatge. Tenen la possibilitat d’experimentar el paper de mestres, a partir de la posada en pràctica d’un joc motor. A partir d’aquesta pràctica, he volgut conèixer quins són els components de la pràctica que possibiliten la presa de consciència de les actituds presents a les sessions de classe per promoure l’educació en valors. Els instruments utilitzats, en la realització d’aquest treball, són un qüestionari elaborat a partir d’una selecció i justificació de continguts actitudinals, i l’observació d’una fitxa sessió després de la pràctica. El treball de recerca se situa en un paradigma interpretatiu i pràctic. Es planteja comprendre la importància que té, en les sessions de classe d’educació física, el desenvolupament de processos d’acció i de reflexió en la formació inicial dels mestres de primària i així examinar i perfeccionar futures intervencions pràctiques, tant del professorat com dels estudiants de mestre.

How multiple repetitions influence the processing of self-, famous and unknown names and faces: an ERP study.

Because we live in an extremely complex social environment, people require the ability to memorize hundreds or thousands of social stimuli. The aim of this study was to investigate the effect of multiple repetitions on the processing of names and faces varying in terms of pre-experimental familiarity. We measured both behavioral and electrophysiological responses to self-, famous and unknown names and faces in three phases of the experiment (in every phase, each type of stimuli was repeated a pre-determined number of times). We found that the negative brain potential in posterior scalp sites observed approximately 170 ms after the stimulus onset (N170) was insensitive to pre-experimental familiarity but showed slight enhancement with each repetition. The negative wave in the inferior-temporal regions observed at approximately 250 ms (N250) was affected by both pre-experimental (famous>unknown) and intra-experimental familiarity (the more repetitions, the larger N250). In addition, N170 and N250 for names were larger in the left inferior-temporal region, whereas right-hemispheric or bilateral patterns of activity for faces were observed. The subsequent presentations of famous and unknown names and faces were also associated with higher amplitudes of the positive waveform in the central-parietal sites analyzed in the 320-900 ms time-window (P300). In contrast, P300 remained unchanged after the subsequent presentations of self-name and self-face. Moreover, the P300 for unknown faces grew more quickly than for unknown names. The latter suggests that the process of learning faces is more effective than learning names, possibly because faces carry more semantic information.

THE USE OF SIMULATIONS IN EVOLUTIONARY POPULATION GENETICS: APPLICATIONS ON HUMANS, OWLS AND VIRTUAL ORGANISMS

Summary (in English) Computer simulations provide a practical way to address scientific questions that would be otherwise intractable. In evolutionary biology, and in population genetics in particular, the investigation of evolutionary processes frequently involves the implementation of complex models, making simulations a particularly valuable tool in the area. In this thesis work, I explored three questions involving the geographical range expansion of populations, taking advantage of spatially explicit simulations coupled with approximate Bayesian computation. First, the neutral evolutionary history of the human spread around the world was investigated, leading to a surprisingly simple model: A straightforward diffusion process of migrations from east Africa throughout a world map with homogeneous landmasses replicated to very large extent the complex patterns observed in real human populations, suggesting a more continuous (as opposed to structured) view of the distribution of modern human genetic diversity, which may play a better role as a base model for further studies. Second, the postglacial evolution of the European barn owl, with the formation of a remarkable coat-color cline, was inspected with two rounds of simulations: (i) determine the demographic background history and (ii) test the probability of a phenotypic cline, like the one observed in the natural populations, to appear without natural selection. We verified that the modern barn owl population originated from a single Iberian refugium and that they formed their color cline, not due to neutral evolution, but with the necessary participation of selection. The third and last part of this thesis refers to a simulation-only study inspired by the barn owl case above. In this chapter, we showed that selection is, indeed, effective during range expansions and that it leaves a distinguished signature, which can then be used to detect and measure natural selection in range-expanding populations. Résumé (en français) Les simulations fournissent un moyen pratique pour répondre à des questions scientifiques qui seraient inabordable autrement. En génétique des populations, l'étude des processus évolutifs implique souvent la mise en oeuvre de modèles complexes, et les simulations sont un outil particulièrement précieux dans ce domaine. Dans cette thèse, j'ai exploré trois questions en utilisant des simulations spatialement explicites dans un cadre de calculs Bayésiens approximés (approximate Bayesian computation : ABC). Tout d'abord, l'histoire de la colonisation humaine mondiale et de l'évolution de parties neutres du génome a été étudiée grâce à un modèle étonnement simple. Un processus de diffusion des migrants de l'Afrique orientale à travers un monde avec des masses terrestres homogènes a reproduit, dans une très large mesure, les signatures génétiques complexes observées dans les populations humaines réelles. Un tel modèle continu (opposé à un modèle structuré en populations) pourrait être très utile comme modèle de base dans l'étude de génétique humaine à l'avenir. Deuxièmement, l'évolution postglaciaire d'un gradient de couleur chez l'Effraie des clocher (Tyto alba) Européenne, a été examiné avec deux séries de simulations pour : (i) déterminer l'histoire démographique de base et (ii) tester la probabilité qu'un gradient phénotypique, tel qu'observé dans les populations naturelles puisse apparaître sans sélection naturelle. Nous avons montré que la population actuelle des chouettes est sortie d'un unique refuge ibérique et que le gradient de couleur ne peux pas s'être formé de manière neutre (sans l'action de la sélection naturelle). La troisième partie de cette thèse se réfère à une étude par simulations inspirée par l'étude de l'Effraie. Dans ce dernier chapitre, nous avons montré que la sélection est, en effet, aussi efficace dans les cas d'expansion d'aire de distribution et qu'elle laisse une signature unique, qui peut être utilisée pour la détecter et estimer sa force.
