Diez recomendaciones para mejorar la enseñanza de la Geriatría en el pregrado

IntroductionPopulation ageing and scientific progress have made specific training in Geriatrics essential for any medical students. There are different international recommendations on the teaching of Geriatric Medicine at undergraduate level, but they are still far from being offered systematically. The aim of this work was to develop a National list of recommendations in order to improve training in Geriatric Medicine at the undergraduate level.Material and methodsA list of 10 recommendations was produced by reflecting on the Geriatric training situation in Spain in 2016/2017 and international recommendations. Consensus was reached among the members of the Spanish Society of Geriatrics and Gerontology (SEGG) working group on «Geriatric training at undergraduate level» through 2 meetings and online discussions.ResultsA list of 10 of recommendations on Geriatric training in Spanish Medical Schools is proposed, including areas such as, the status of the discipline in the curriculum, length, contents, practical training, lecturers, teaching methods, and innovation.ConclusionsThese recommendations are intended to improve Geriatrics training. They can be used by different Medical Schools either to adapt their programs or to start training in Geriatric Medicine.     

Does the Spanish version of the SWLS measure the same in Spain and Peru?

AimSatisfaction with life is a measure of protection in older adults. There lies the importance of providing quality instruments. The aim of the study was to evaluate the invariance of the life satisfaction scale (SWLS) in two samples of older adults in Spain and Peru.MethodThe participants were 857 older adults in Spain (mean age = 68.23 years, SD = 5.93) and 336 older adults in Peru (average age = 72.42, SD = 7.07). All multi-group confirmatory factor analyzes were estimated in Mplus 8.0.ResultsThe results indicate the presence of a strict invariance of the one-dimensional structure of the SWLS in samples of older adults in Spain and Peru, which allows for meaningful comparisons of latent means and covariances. Comparison of latent means showed small differences in the construct between the cultural groups.ConclusionsThe SWLS is a valid instrument for intercultural comparisons between Spanish and Peruvian population. The measurement invariance assessment contributes to a better understanding of life satisfaction in populations from different cultural contexts.     

Expresión sexual y regulación de la sexualidad en residencias de personas mayores

Objectives

The study had three objectives: (a) To determine how staff perceives the frequency of different sexual expressions in long-term care facilities for older people; (2) to quantify policies aimed at guaranteeing residents’ sexual rights in such institutions, and (3) to determine factors influencing the presence of these kind of policies.

Lateglacial and Holocene vegetation history in the mountain range of central Pyrenees

We present the pollen analysis of a new sedimentary sequence taken at La Pouretère ( 1720 m), in the mountain vegetation zone of the Marcadau valley (central Pyrenees). The Lateglacial and Holocene chronology is supported by six 14C-dating results. The complementary analysis of some vegetal macroremains, stomata, pollen-clusters and the use of pollen influx allows us to elucidate the dynamic of mountain species such as Pinus and specially Abies but also to infer the unusual part played by Betula at the beginning of the Postglacial period.     

Adaptations of the hoatzin (Opisthocomus hoazin) to leaf-eating. Morphological characteristics and functional features of its bill and hyoid apparatus

The hoatzin remains one of the most enigmatic birds. A morphofunctional analysis of its bill and hyoid apparatus throws new light on its feeding adaptation as well as on its systematic relationships. Bony and muscular skull, rhamphotheca, palate, and hyoid apparatus were described in details. Though keeping into the general organisation pattern found among Neognathae (except Galliformes), bill and hyoid apparatus of the hoatzin displays a series of species-specific features, some unique among birds. This species appears particularly well adapted to tear of leaves and process them inside the bill before ingestion. Because of very important anatomical and thence functional differences in bill and hyoid structure, any close relationship between the hoatzin and Galliformes cannot be envisioned. Such a hypothesis would implicate a counter-selective evolutionary reversion.     

Nouvelles données sur le genre Imerites Rouchadzé, 1933 (Ammonitida,Ancyloceratina) ; réponses et précisions apportées au travail de Bert,Delanoy et Canut, 2009

This work is mainly an answer to the work of Bert, Delanoy and Canut, on the genus Imerites Rouchadzé, and we add also some points to the knowledge of this genus. An answer is given for the implication of one of the authors (J.V.) of this present work, about the origin of the genus Imerites Rouchadzé, and some significant bibliographic references, not named in the 2009 work, are specified and placed in their context. The characteristics of the ornamental stage “Pseudoshasticrioceras” mainly defined by an oval and compressed section of the whorls and by regular ventrolateral clavi, well marked, which frame the venter in a typical way (Bert et al., p. 181), don’t allow to affirm the presence of this stage during the ontogeny of all species of the genus Imerites Rouchadzé, contrary to what Bert, Delanoy and Canut (p. 30, 31) wrote. The type-species of the genus Imerites Rouchadzé is made clear by the application of the rules of the I.C.Z.N. code. The article 23, with the paragraph 23.1 of the I.C.Z.N. code, imply the senior synonymy of Imerites cristatus (Orbigny) on Imerites giraudi (Kilian), even if the Kilian's species is still the type species of the genus Imerites Rouchadzé. The taxinomical validity of the species Imerites cristatus (Orbigny) is confirmed. Its morphological variability is clarified by the distinction of four referential morphotypes, Cristatus, Giraudi, Favrei and Raricostatum. Consequently, the assumption of a shape-dimensional dimorphism into the populations of the genus Imerites Rouchadzé is rejected, awaiting irrefutable proof. A new species, Imerites stephaniae sp. nov., is described. It was collected in the Gerhardtia sartousiana Zone, in the uppermost part of the Gerhardtia provincialis Subzone, and it is a probable ancestor of the cogeneric species of the Imerites giraudi Zone.     

Genetic polymorphism of glutamine synthetase and delta-9 desaturase in families of Pacific oyster Crassostrea gigas and susceptibility to summer mortality

Large-scale mortality events have been observed in Pacific oyster Crassostrea gigas on the west coast of France since the early 1980s, particularly during summer. In order to understand the causes of this mortality, two generations of oysters from single-pair matings were studied in three sites on the French Atlantic coast (Baie-des-Veys, Auray and Ronce-les-Bains). The present paper examines the role of two candidate genes in the susceptibility of oysters to summer mortality, and the selective pressure exerted by such mortality on their polymorphism. Glutamine synthetase (amino-acid metabolism) and delta-9 desaturase (lipid metabolism) genes were studied in the successive generations, using polymerase chain reaction single-strand conformation polymorphism (PCR-SSCP). Observed and expected genotypic frequencies were compared. Three different alleles were detected for the glutamine synthetase gene and two for delta-9 desaturase. Allele C of glutamine synthetase seemed to be counter-selected in some second generation families. Allele B of delta-9 desaturase gene was potentially counter-selected at Auray in the families showing higher mortality, and strong selection against BB homozygotes was observed. These observations led us to conclude that any selective effect of summer mortality on allele C of glutamine synthetase gene or allele B of delta-9 desaturase gene could be mediated either directly or via linkage to other loci involved in physiological pathways affecting susceptibility.     

Les Megacricetodon du gisement karstique miocène moyen de Blanquatère 1 (Pyrénées-Orientales, Sud de la France) : nouvelles espèces, implications biochronologique et phylogénique

Three Megacricetodon species are recognized in the Middle Miocene locality of Blanquatère 1 (Languedoc-Roussillon province, France). Two are new, the small-sized M. tautavelensis nov. sp. the medium to large-sized M. aunayi nov. sp., the third one being the already known M. “collongensis-gersii”, a medium-sized species found in other Miocene localities of the area. Size and morphology differentiate these species. Such a high number of contemporaneous species of the genus Megacricetodon is found for the first time in a Miocene locality in the region and indicate that the evolution of this genus in western Europe is likely more complicated. It may testify both of a biogeographical differentiation and of migration events. According to our calibration charts, the deposit is dated ca. 16 Ma ago. The position of Vieux-Collonges (MN 5) and Sansan (MN 6) on the biochronological scale is also discussed, as well as the estimated age of the biozonal boundaries MN 3/MN 4, MN 4/MN 5 and MN 5/MN 6.
