Desigualdades en el acceso a los programas preventivos en salud sexual y reproductiva

La presente revisión tiene como objetivos analizar si dentro de los programas preventivos europeos de salud sexual y reproductiva existen barreras de acceso, identificar qué grupos son más vulnerables respecto a la prevención y conocer estrategias que permitan un mejor acceso a dichos programas. El método es una revisión de la bibliografía publicada en los últimos 10 años sobre iniciativas de prevención en salud sexual y reproductiva en Europa. Los resultados muestran la existencia de desigualdades en el acceso, y se identifican propuestas para contribuir a su disminución. La conclusión principal es que las mujeres con condiciones socioeconómicas desfavorables tendrán un mayor riesgo de exclusión si no se aplican medidas correctoras en el diseño de los programas.

Moths behaving like butterflies. Evolutionary loss of long range attractant pheromones in Castniid Moths: A Paysandisia archon model

Background: In the course of evolution butterflies and moths developed two different reproductive behaviors. Whereas butterflies rely on visual stimuli for mate location, moths use the"female calling plus male seduction" system, in which females release long-range sex pheromones to attract conspecific males. There are few exceptions from this pattern but in all cases known female moths possess sex pheromone glands which apparently have been lost in female butterflies. In the day-flying moth family Castniidae ("butterfly-moths"), which includes some important crop pests, no pheromones have been found so far. Methodology/Principal Findings: Using a multidisciplinary approach we described the steps involved in the courtship of P. archon, showing that visual cues are the only ones used for mate location; showed that the morphology and fine structure of the antennae of this moth are strikingly similar to those of butterflies, with male sensilla apparently not suited to detect female-released long range pheromones; showed that its females lack pheromone-producing glands, and identified three compounds as putative male sex pheromone (MSP) components of P. archon, released from the proximal halves of male forewings and hindwings. Conclusions/Significance: This study provides evidence for the first time in Lepidoptera that females of a moth do not produce any pheromone to attract males, and that mate location is achieved only visually by patrolling males, which may release a pheromone at short distance, putatively a mixture of Z,E-farnesal, E,E-farnesal, and (E,Z)-2,13-octadecadienol. The outlined behavior, long thought to be unique to butterflies, is likely to be widespread in Castniidae implying a novel, unparalleled butterfly-like reproductive behavior in moths. This will also have practical implications in applied entomology since it signifies that the monitoring/control of castniid pests should not be based on the use of female-produced pheromones, as it is usually done in many moths.

Phylogeography of competing sexual and parthenogenetic forms of a freshwater flatworm: patterns and explanations

Background: Models of the maintenance of sex predict that one reproductive strategy, sexual or parthenogenetic, should outcompete the other. Distribution patterns may reflect the outcome of this competition as well as the effect of chance and historical events. We review the distribution data of sexual and parthenogenetic biotypes of the planarian Schmidtea polychroa. Results: S. polychroa lives in allopatry or sympatry across Europe except for Central and North-Western Europe, where sexual individuals have never been reported. A phylogenetic relationship between 36 populations based on a 385 bp fragment of the mitochondrial cytochrome oxidase I gene revealed that haplotypes were often similar over large geographic distances. In North Italian lakes, however, diversity was extreme, with sequence differences of up to 5% within the same lake in both sexuals and parthenogens. Mixed populations showed "endemic" parthenogenetic lineages that presumably originated from coexisting sexuals, and distantly related ones that probably result from colonization by parthenogens independent from sexuals. Conclusions: Parthenogens originated repeatedly from sexuals, mainly in Italy, but the same may apply to other Mediterranean regions (Spain, Greece). The degree of divergence between populations suggests that S. polychroa survived the ice ages in separate ice-free areas in Central, Eastern and Southern Europe and re-colonised Europe after the retreat of the major glaciers. Combining these results with those based on nuclear markers, the data suggest that repeated hybridisation between sexuals and parthenogenetic lineages in mixed populations maintains high levels of genetic diversity in parthenogens. This can explain why parthenogens persist in populations that were originally sexual. Exclusive parthenogenesis in central and western populations suggests better colonisation capacity, possibly because of inbreeding costs as well

Valoració de la qualitat de vida dels familiars de pacients amb fibromiàlgia

Fonament i objectiu: La Fibromiàlgia (FM) és una malaltia reumàtica caracteritzada per dolor generalitzat, que afecta a un tant per cent elevat de la població general , majoritàriament dones i d’etiologia desconeguda, i que pensem que no afecta tan sols als qui la pateixen, sinó que també als seus familiars. En aquest estudi s’han avaluat diferents variables com l’impacte emocional, la vida social, aspectes econòmics i laborals i altres activitats en familiars de primer grau de pacients amb FM. L’objectiu principal és determinar quin és el grau d’afectació negativa en la seva qualitat de vida. Material i mètodes: Es va fer un estudi observacional clínic a un grup de 27 familiars de 1er grau que convivien a la mateixa casa que els respectius afectats per FM. Se’ls va passar un qüestionari ad- hoc de 16 preguntes tancades, basades en estudis previs , i també una entrevista oberta amb l’objectiu de reforçar les dades estadístiques. Les entrevistes es varen fer a la Unitat de Fibromiàlgia de l’Hospital Santa Maria de Lleida. Resultats: Es va entrevistar a 27 familiars, 85’2 % homes, la majoria de entre 51 – 70 anys (63%). El 85’2 % eren casats, amb estudis primaris el 59’3% i el 88% tenien coneixements sobre la malaltia del familiar afectat. El percentatge de familiars que van opinar que hi havia una minva del grau de felicitats amb la malaltia era del 74’1%. El 85% no havia pensat mai en trencar la relació familiar. El 70% referien canvis en la vida social i relacional arrel del diagnòstic de FM , un 88’9% havien tingut que augmentar l’ajut en tasques domèstiques i el 70’4% patien efectes econòmics negatius arrel de la malaltia. La relació sexual es va veure afectada en un 85% dels casos, en canvi no es varen veure alteracions del son ni de la percepció de salut. Conclusions: El fet de conviure amb una persona afectada de FM suposa pèrdua del grau de felicitat i canvis en la vida social, relacional i sexual amb empitjorament del nivell econòmic.

Pubic growth study: applicability in sexual and age diagnostic.

The growth of five variables of the ischiopubic area was analyzed from bone material from birth to old age. The main purpose was to evaluate its significance and capacity for age and sex determination during and after growth. The material used consisted of 327 specimens from four documented Western European collections. Growth curves were calculated by polynomial regression for two classical variables of the ischiopubic area (pubis length and ischiopubic index) and three new variables of the pubic acetabular area (horizontal and vertical diameter of the pubic acetabular area and the pubic acetabular index). None of the curves showed lineal growth, with the exception of the ischiopubic index and the masculine vertical diameter of the pubis acetabular area. Pubis length has the most complicated growth, expressed by a five-degree polynomial. All the variables are useful for adult sex determination, except the pubic acetabular index. The ischopubic index, vertical diameter of the pubic acetabular area and the pubic acetabular index seem to be good variables for sub-adult sex determination. For age estimation the best variables, in both archaeological and forensic remains, are the absolute measurements (pubic length, vertical and horizontal diameter of the pubis). However, pubis length is the best variable for age estimation because it can be applied until 25 years of age.

Phylogenetic relationships of the newly discovered sexual state of Talaromyces flavovirens, comb. nov.

Typical Talaromyces ascomata were observed on dry Quercus suber leaf litter amongst the characteristic synnemata of Penicillium aureocephalum, and they appear to represent the sexual state of the latter species. The species is a synonym of the older Lasioderma flavovirens, and we propose the new combination Talaromyces flavovirens. Lectotype and epitype specimens are designated for this name. The defining characters of the asexual state include yellow, short-stalked, mycetozoan-like synnemata with an unusual, almost closed terminal head of penicillate conidiophores intermixed with sinuous hyphae, and dark green conidia. Ascomata could not be induced in culture, but PCR amplifications of mating-type genes indicate the species is heterothallic. In nature, ascocarp initials appear to be antheridia coiled around clavate ascogonia, similar to those of T. flavus, and the thick-walled, spiny ascospores are also similar to those of T. flavus. ITS barcodes and β-tubulin sequences place T. flavovirens in a clade with T. apiculatus, T. flavus, T. funiculosus, T. galapagensis, T. pinophilus, T. macrosporus, and seven other species.

Avaluació del sistema de confusió sexual pel control de carpocapsa (Cydia pomonella L.) en plantacions de pomeres de Fructícola Empordà S.L. durant el període 2003-2011

La carpocapsa o corc de la poma (Cydia pomonella L.) és la plaga clau de lesplantacions comercials de pomera de la zona de Girona. Per controlar-la amb eficàcia,anualment són necessaris diferents tractaments insecticides que a més del cost econòmicque representen, afavoreixen fenòmens de resistències, aparició de plagues induïdes iproblemes de toxicitat, residus i contaminació ambiental.La combinació de diferents metodologies per combatre aquesta plaga, algunes menysagressives amb la fauna auxiliar i el medi ambient, s’ha convertit en una pràcticaimprescindible per aconseguir-ne un control efectiu i sostenible.

Necesidades educativas para promover la salud afectiva y sexual en jóvenes en riesgo social

La educación afectiva y sexual de los y las jóvenes en situación de riesgo social es un elemento esencial para su salud. La educación en esta área requiere unos planteamientos rigurosos que se basen en las necesidades educativas y diferenciales de este colectivo en relación a la salud afectiva y sexual. El presente artículo presenta los resultados de una investigación que analiza estas necesidades. Para ello, se diseñó una investigación acción participativa de carácter cualitativa, en la cual participaron 48 profesionales y 72 jóvenes. La recogida de información se realizó mediante grupos de discusión. Los resultados constatan que el factor cultural y la historia personal y familiar son variables que tienen un carácter concluyente en los comportamientos sexuales de este colectivo. Estas variables deben considerarse, tanto en la educación formal como en la no formal, con tal de promover la salud afectiva sexual, haciendo especial hincapié en los aspectos emocionales, afectivos y sociales.

Educación en Valores y Diferencia Sexual: Realidad y políticas educativas en el contexto español

Este artículo analiza para el contexto español las políticas promovidas en los últimos años por el gobierno conservador del partido popular y los cambios que conllevaron la entrada en vigor, en el 2002, de la Ley de Calidad de la Enseñanza. Los mismos no parecen garantizar la igualdad de oportunidades para las mujeres, pues nos encontramos ante una Ley cuya finalidad es buscar respuestas a los cambios tecnológicos y los criterios de mercado, llegando a afirmarse que las reformas educativas son necesarias para la “revisión, ajuste y mejora”, siendo la “calidad” el mecanismo para “el logro de cotas más elevadas de progreso social y económico”. A pesar de que la exposición de motivos de la Ley alude al bienestar individual y social –sin explicitar abiertamente el significado que les otorga-, los planteamientos neoliberales de las economías capitalistas se insertan en el discurso y se habla, como se ha indicado, de la necesidad de ajustes que en estas perspectivas no garantizan el avance en la lucha contra la exclusión y la discriminación, dificultando el encuentro de las diferencias, de lo femenino y de lo masculino. El nuevo gobierno socialista, surgido de las elecciones celebradas en el pasado mes de marzo de 2004, forzosamente debe plantear una transición educativa que necesita de medidas urgentes, atrevidas y transformadoras.

Danza movimiento terapia y abuso sexual

L'organització mundial de la salut, assenyala que la major part de les agressions sexuals tenen com a víctimes a dones i nenes, i són perpetrades per homes i nens. En alguns països, gairebé una de cada quatre dones ha estat víctima de violència sexual per part de la seva parella i fins a una tercera part de les adolescents han sofert una iniciació sexual forçada. Estudis especialitzats fan referència al percentatge de dones que han sofert alguna forma d'abús sexual abans dels 18 anys. En el mateix sentit, enquestes mundials assenyalen que entre el 10% i el 69% de les dones diuen haver estat agredides físicament per una parella masculina en algun moment de la seva vida. La violència sexual infantil provoca a les seves víctimes una sèrie de repercussions i seqüeles, psicològiques, emocionals, socials; compromet el desenvolupament integral de l'individu, i provoca l'aparició d'una sèrie de patologies a l'edat adulta. La present investigació fa una revisió teòrica de la violència sexual, de la violència de gènere, i de les aportacions del procés de recuperació a través de la dansa moviment teràpia d'aquesta població. També es mostra el recorregut del marc d'actuació dels organismes d'ordre públic de la ciutat de Barcelona per a l'atenció i detecció en casos d'abús sexual

Sexual foraging segregation in South American sea lions increases during the pre-breeding period in the La Plata River plume

Stable carbon and nitrogen isotopes in skin and bone of South American sea lions from Brazil and Uruguay were analysed to test the hypothesis that trophic overlap between the sexes is lower during the pre-breeding season than throughout the rest of the year. The isotopic values of skin and bone were used to infer the trophic relationships between the sexes during the pre-breeding period and year round, respectively. Prey species were also analysed to establish a baseline necessary for interpreting the stable isotope ratios of skin and bone. Standard ellipse areas, estimated using Bayesian inference in the SIBER routine of the SIAR package in R, suggested that males and females used a wide diversity of foraging strategies throughout the year and that no differences existed between the sexes. However, the diversity of foraging strategies was largely reduced during the pre-breeding period, with all the individuals of each sex adopting similar strategies, but with the two sexes differing considerably in stable isotope values and the ellipse areas of males and females not overlapping at all. Nevertheless, the results revealed a general increase in the consumption of pelagic prey by both sexes during the pre-breeding period. The progressive crowding of individuals in the areas surrounding the breeding rookeries during the pre-breeding period could lead to an increase in the local population density, which could explain the above reported changes.

Ralstonia solanacearum, a widespread bacterial plant pathogen in the post-genomic era

Ralstonia solanacearum is a soil-borne bacterium causing the widespread disease known as bacterial wilt. Ralstonia solanacearum is also the causal agent of Moko disease of banana and brown rot of potato. Since the last R. solanacearum pathogen profile was published 10 years ago, studies concerning this plant pathogen have taken a genomic and post-genomic direction. This was pioneered by the first sequenced and annotated genome for a major plant bacterial pathogen and followed by many more genomes in subsequent years. All molecular features studied now have a genomic flavour. In the future, this will help in connecting the classical field of pathology and diversity studies with the gene content of specific strains. In this review, we summarize the recent research on this bacterial pathogen, including strain classification, host range, pathogenicity determinants, regulation of virulence genes, type III effector repertoire, effector-triggered immunity, plant signalling in response to R. solanacearum, as well as a review of different new pathosystems.

Temperature-Specific Competition between Invasive Mosquitofish and an Endangered Cyprinodontid Fish

Condition-specific competition is widespread in nature. Species inhabiting heterogeneous environments tend to differ in competitive abilities depending on environmental stressors. Interactions between these factors can allow coexistence of competing species, which may be particularly important between invasive and native species. Here, we examine the effects of temperature on competitiveinteractions between invasive mosquitofish, Gambusia holbrooki, and an endemic Iberian toothcarp, Aphanius iberus. We compare the tendency to approach heterospecifics and food capture rates between these two species, and examine differences between sexes and species in aggressive interactions, at three different temperatures (19, 24 and 29uC) in three laboratory experiments. Mosquitofish exhibit much more aggression than toothcarp. We show that mosquitofish have the capacity to competitively displace toothcarp through interference competition and this outcome is more likely at higher temperatures. We also show a reversal in the competitive hierarchy through reduced food capture rate by mosquitofish at lower temperatures and suggest that these two types of competition may act synergistically to deprive toothcarp of food at higher temperatures. Males of both species carry out more overtly aggressive acts than females, which is probably related to the marked sexual dimorphism and associated mating systems of these two species. Mosquitofish may thus impact heavily on toothcarp, and competition from mosquitofish, especially in warmer summer months, may lead to changes in abundance of the native species and displacement to non-preferred habitats. Globally increasing temperatures mean that highly invasive, warm-water mosquitofish may be able to colonize environments from which they are currently excluded through reduced physiological tolerance to low temperatures. Research into the effects of temperature on interactions between native and invasive species is thus of fundamental importance

Sexual dimorphism of sonic apparatus and extreme intersexual variation of sounds in Ophidion rochei (Ophidiidae): first evidence of a tight relationship between morphology and sound characteristics in Ophidiidae

Many Ophidiidae are active in dark environments and display complex sonic apparatus morphologies. However, sound recordings are scarce and little is known about acoustic communication in this family. This paper focuses on Ophidion rochei which is known to display an important sexual dimorphism in swimbladder and anterior skeleton. The aims of this study were to compare the sound producing morphology, and the resulting sounds in juveniles, females and males of O. rochei.Results: Males, females, and juveniles possessed different morphotypes. Females and juveniles contrasted with males because they possessed dramatic differences in morphology of their sonic muscles, swimbladder, supraoccipital crest, and first vertebrae and associated ribs. Further, they lacked the ‘rocker bone’ typically found in males. Sounds from each morphotype were highly divergent. Males generally produced non harmonic, multiple-pulsed sounds that lasted for several seconds (3.5 ± 1.3 s) with a pulse period of ca. 100 ms. Juvenile and female sounds were recorded for the first time in ophidiids. Female sounds were harmonic, had shorter pulse period (±3.7 ms), and never exceeded a few dozen milliseconds (18 ± 11 ms). Moreover, unlike male sounds, female sounds did not have alternating long and short pulse periods. Juvenile sounds were weaker but appear to be similar to female sounds.Conclusions: Although it is not possible to distinguish externally male from female in O. rochei, they show a sonic apparatus and sounds that are dramatically different. This difference is likely due to their nocturnal habits that may have favored the evolution of internal secondary sexual characters that help to distinguish males from females and that could facilitate mate choice by females. Moreover, the comparison of different morphotypes in this study shows that these morphological differences result from a peramorphosis that takes place during the development of the gonads
