Acceptability of pandemic A(H1N1) influenza vaccination by Essential Community Workers in 2010 Alicante (Spain), perceived seriousness and sources of information

Objective. Describe acceptability of pandemic A(H1N1) influenza vaccination by Essential Community Workers (ECWs) from Alicante province (Spain) in January 2010. Evaluate the correlation with attitudes, beliefs, professional advice and information broadcasted by media. Method. In this cross-sectional study, face-to-face interviews were conducted with 742 ECWs to assess their attitudes towards vaccination against the pandemic influenza strain. A multivariable regression model was made to adjust the Odds Ratios (ORs). Results. Some ECWs reported having been vaccinated with seasonal vaccine, 21.5% (95%IC 18.6–24.9); only 15.4% (95%IC 12.8–18.4) with the pandemic one. ECWs vaccinated regularly against seasonal flu (OR 5.1; 95%IC 2.9–9.1), those who considered pandemic influenza as a severe or more serious disease than seasonal flu (OR 3.8; 95%IC 2.1–6.7) and those who never had doubts about vaccine safety (OR 3.7; 95%IC2.1–6.7) had a better acceptance of pandemic vaccine. Finally, 78.7% (95%IC 75.1–81.4) had doubts about pandemic vaccine's effectiveness. Conclusion. The vast amount of information provided by the media did not seem to be decisive to prevent doubts or to improve the acceptability of the vaccine in ECWs. Professional advice should be the focus of interest in future influenza vaccination campaigns. These results should be taken into account by health authorities.

Perfil sociodemográfico del feminicidio en España y su relación con las denuncias por violencia de pareja

Objetivo: Analizar las características asociadas al riesgo de feminicidio en España entre mujeres expuestas a la violencia de pareja o análogo y su posible asociación con las denuncias a los agresores. Métodos: Se realizó un estudio de casos y controles para el periodo 2010-2011. Los casos, 135 mujeres mayores de edad, asesinadas por su pareja o análogo durante dicho periodo, se identificaron a través de la página web de la Federación de Asociaciones de Mujeres Separadas y Divorciadas, y de los informes del Consejo General del Poder Judicial. Los controles, 185 mujeres expuestas a la violencia de pareja el último año, proceden de la Macroencuesta de Violencia de Género 2011. La asociación entre la denuncia y el riesgo de feminicidio se estimó mediante modelos de regresión logística multivariada. Resultados: No se encontró asociación entre denunciar al agresor y el riesgo de ser asesinada (odds ratio [OR]: 1,38; intervalo de confianza del 95% [IC95%]: 0,68-2,79). Las mujeres inmigrantes expuestas a la violencia de pareja registraron una mayor probabilidad de ser asesinadas (ref.: mujeres españolas; OR: 5,38; IC95%: 2,41-11,99). Esta asociación también se observó en las mujeres que vivían en zonas rurales (ref: zonas urbanas; OR: 2,94; IC95%: 1,36-6,38). Conclusiones: La denuncia judicial al agresor no parece modificar el riesgo de asesinato entre las mujeres expuestas a la violencia de pareja. Las medidas de protección a las mujeres deberían extremarse en las mujeres inmigrantes y las que viven en el medio rural.

Corrélats neuronaux du circuit des récompenses chez les jeunes à risque parental de troubles de l'humeur

Cette thèse a pour objectif l’investigation du circuit des récompenses, sur les plans comportementaux et neuronaux, chez des adolescents à risque parental élevé de dépression majeure et de trouble bipolaire, en comparaison à des jeunes à risque parental peu élevé. Plus précisément, le but est d’identifier des marqueurs comportementaux et neuronaux du risque de développer une dépression majeure ou un trouble bipolaire, afin d’être en mesure de détecter et de prévenir ces troubles le plus tôt possible pour éviter, ou du moins retarder, leur émergence. Pour ce faire, nous avons réalisé deux études, présentées ici dans deux articles empiriques. Dans le premier article, le fonctionnement comportemental et neuronal du circuit des récompenses a été investigué au moyen d’une tâche d’anticipation et d’obtention de gains et de pertes monétaires, chez des adolescents à risque parental de dépression majeure (i.e., jeunes asymptomatiques dont un des parents souffre de dépression majeure), des adolescents à risque parental de trouble bipolaire (i.e., jeunes asymptomatiques dont un des parents souffre de trouble bipolaire) et des adolescents contrôles (i.e., jeunes asymptomatiques dont les deux parents sont en bonne santé mentale). Au niveau comportemental, les résultats ont révélé une meilleure performance chez les jeunes à risque de dépression majeure lorsqu’ils devaient éviter d’obtenir des pertes monétaires de magnitude variée (0,20$, 1$ ou 5$), ainsi qu’une meilleure performance chez les jeunes à risque de trouble bipolaire sur les essais impliquant d’éviter des pertes monétaires de magnitude nulle (0$). Au niveau neuronal, les jeunes à risque de dépression majeure démontraient une diminution de l’activation du cortex préfrontal dorsolatéral lors de l’anticipation de potentielles pertes monétaires de magnitude variée, tandis que les jeunes à risque de trouble bipolaire démontraient une diminution de l’activation du cortex préfrontal dorsolatéral lors de l’anticipation de potentielles pertes monétaires de magnitude nulle. De plus, les jeunes à risque de dépression majeure tendaient à démontrer une augmentation de l’activité du cortex orbitofrontal durant l’évitement réussi de pertes monétaires, tandis que les jeunes à risque de trouble bipolaire tendaient à démontrer une augmentation de l’activité du cortex orbitofrontal lors de l’obtention de pertes monétaires. Dans le deuxième article, l’intégrité structurelle des régions fronto-limbiques a été investiguée, au moyen de mesures du volume, de l’épaisseur corticale et de la superficie corticale. Les résultats ont mis en évidence, chez les jeunes à risque de trouble bipolaire, un volume plus élevé du cortex préfrontal dorsolatéral, par rapport aux jeunes à risque de dépression majeure et contrôles. De plus, les jeunes à risque de trouble bipolaire présentaient un volume plus élevé du cortex cingulaire postérieur, en comparaison aux jeunes à risque de dépression majeure. Enfin, une diminution de l’épaisseur corticale du cortex orbitofrontal et du gyrus frontal moyen a été observée chez les adolescents à risque de trouble bipolaire, en comparaison au groupe contrôle. L’ensemble de ces résultats démontre ainsi l’existence de particularités comportementales et d’altérations neuronales sur les plans fonctionnel et structurel, chez des jeunes à risque élevé de troubles de l’humeur, et ce, avant même l’émergence des premiers symptômes thymiques. Plus particulièrement, ces caractéristiques pourraient constituer des marqueurs du risque de développer un trouble de l’humeur. Par conséquent, ces marqueurs pourraient aider à mieux identifier les jeunes qui sont le plus à risque de développer un trouble de l’humeur, et ainsi permettre la mise en place précoce de stratégies préventives adaptées, afin d’éviter des trajectoires développementales psychopathologiques.

Predictors of Nasal Obstruction: Quantification and Assessment Using Multiple Grading Scales

Objective. To evaluate the association between nasal obstruction and (1) demographic factors, (2) medical history, (3) physical tests, and (4) nasal exam findings. Study Design. CASE SERIES: Methods. Chart review at a tertiary medical center. Results. Two hundred-forty consecutive patients (52.1 ± 17.5 years old, with a Nasal Obstruction Symptom Evaluation (NOSE) score of 32.0 ± 24.1) were included. Demographic factors and inferior turbinate sizes were not associated with NOSE score or Nasal Obstruction Visual Analog Scale (NO-VAS). A significant association was found between higher NOSE score on univariate analysis and positive history of nasal trauma (p = 0.0136), allergic rhinitis (p < 0.0001), use of nasal steroids (p = 0.0108), higher grade of external nasal deformity (p = 0.0149), higher internal nasal septal deviation grade (p = 0.0024), and narrow internal nasal valve angle (p < 0.0001). Multivariate analysis identified the following as independent predictors of high NOSE score: NO-VAS: ≥50 (Odds Ratio (OR) = 17.6 (95% CI 5.83-61.6), p < 0.0001), external nasal deformity: grades 2-4 (OR = 4.63 (95% CI 1.14-19.9), p = 0.0339), and allergic rhinitis: yes (OR = 5.5 (95% CI 1.77-18.7), p = 0.0041). Conclusion. Allergic rhinitis, NO-VAS score ≥ 50, and external nasal deformity (grades 2-4) were statistically significant independent predictors of high NOSE scores on multivariate analysis. Inferior turbinate size was not associated with NOSE scores or NO-VAS.

Multiple regulatory variants located in cell type-specific enhancers within the PKP2 locus form major risk and protective haplotypes for canine atopic dermatitis in German shepherd dogs.

BACKGROUND Canine atopic dermatitis (CAD) is a chronic inflammatory skin disease triggered by allergic reactions involving IgE antibodies directed towards environmental allergens. We previously identified a ~1.5 Mb locus on canine chromosome 27 associated with CAD in German shepherd dogs (GSDs). Fine-mapping indicated association closest to the PKP2 gene encoding plakophilin 2. RESULTS Additional genotyping and association analyses in GSDs combined with control dogs from five breeds with low-risk for CAD revealed the top SNP 27:19,086,778 (p = 1.4 × 10(-7)) and a rare ~48 kb risk haplotype overlapping the PKP2 gene and shared only with other high-risk CAD breeds. We selected altogether nine SNPs (four top-associated in GSDs and five within the ~48 kb risk haplotype) that spanned ~280 kb forming one risk haplotype carried by 35 % of the GSD cases and 10 % of the GSD controls (OR = 5.1, p = 5.9 × 10(-5)), and another haplotype present in 85 % of the GSD cases and 98 % of the GSD controls and conferring a protective effect against CAD in GSDs (OR = 0.14, p = 0.0032). Eight of these SNPs were analyzed for transcriptional regulation using reporter assays where all tested regions exerted regulatory effects on transcription in epithelial and/or immune cell lines, and seven SNPs showed allelic differences. The DNA fragment with the top-associated SNP 27:19,086,778 displayed the highest activity in keratinocytes with 11-fold induction of transcription by the risk allele versus 8-fold by the control allele (pdifference = 0.003), and also mapped close (~3 kb) to an ENCODE skin-specific enhancer region. CONCLUSIONS Our experiments indicate that multiple CAD-associated genetic variants located in cell type-specific enhancers are involved in gene regulation in different cells and tissues. No single causative variant alone, but rather multiple variants combined in a risk haplotype likely contribute to an altered expression of the PKP2 gene, and possibly nearby genes, in immune and epithelial cells, and predispose GSDs to CAD.

Spatially explicit estimates of stock size, structure and biomass of North Atlantic albacore tuna (Thunnus alalunga) in the North Atlantic for the period 1987-2011, compiled from statistics about ICCAT fishery region L6

The development of the ecosystem approach and models for the management of ocean marine resources requires easy access to standard validated datasets of historical catch data for the main exploited species. They are used to measure the impact of biomass removal by fisheries and to evaluate the models skills, while the use of standard dataset facilitates models inter-comparison. North Atlantic albacore tuna is exploited all year round by longline and in summer and autumn by surface fisheries and fishery statistics compiled by the International Commission for the Conservation of Atlantic Tunas (ICCAT). Catch and effort with geographical coordinates at monthly spatial resolution of 1° or 5° squares were extracted for this species with a careful definition of fisheries and data screening. In total, thirteen fisheries were defined for the period 1956-2010, with fishing gears longline, troll, mid-water trawl and bait fishing. However, the spatialized catch effort data available in ICCAT database represent a fraction of the entire total catch. Length frequencies of catch were also extracted according to the definition of fisheries above for the period 1956-2010 with a quarterly temporal resolution and spatial resolutions varying from 1°x 1° to 10°x 20°. The resolution used to measure the fish also varies with size-bins of 1, 2 or 5 cm (Fork Length). The screening of data allowed detecting inconsistencies with a relatively large number of samples larger than 150 cm while all studies on the growth of albacore suggest that fish rarely grow up over 130 cm. Therefore, a threshold value of 130 cm has been arbitrarily fixed and all length frequency data above this value removed from the original data set.

Shell preservation of Limacina inflata in surface sediments of the Central and South Atlantic

Over 300 surface sediment samples from the Central and South Atlantic Ocean and the Caribbean Sea were investigated for the preservation state of the aragonitic test of Limacina inflata. Results are displayed in spatial distribution maps and are plotted against cross-sections of vertical water mass configurations, illustrating the relationship between preservation state, saturation state of the overlying waters, and overall water mass distribution. The microscopic investigation of L. inflata (adults) yielded the Limacina dissolution index (LDX), and revealed three regional dissolution patterns. In the western Atlantic Ocean, sedimentary preservation states correspond to saturation states in the overlying waters. Poor preservation is found within intermediate water masses of southern origin (i.e. Antarctic intermediate water (AAIW), upper circumpolar water (UCDW)), which are distinctly aragonite-corrosive, whereas good preservation is observed within the surface waters above and within the upper North Atlantic deep water (UNADW) beneath the AAIW. In the eastern Atlantic Ocean, in particular along the African continental margin, the LDX fails in most cases (i.e. less than 10 tests of L. inflata per sample were found). This is most probably due to extensive "metabolic" aragonite dissolution at the sediment-water interface combined with a reduced abundance of L. inflata in the surface waters. In the Caribbean Sea, a more complex preservation pattern is observed because of the interaction between different water masses, which invade the Caribbean basins through several channels, and varying input of bank-derived fine aragonite and magnesian calcite material. The solubility of aragonite increases with increasing pressure, but aragonite dissolution in the sediments does not simply increase with water depth. Worse preservation is found in intermediate water depths following an S-shaped curve. As a result, two aragonite lysoclines are observed, one above the other. In four depth transects, we show that the western Atlantic and Caribbean LDX records resemble surficial calcium carbonate data and delta13C and carbonate ion concentration profiles in the water column. Moreover, preservation of L. inflata within AAIW and UCDW improves significantly to the north, whereas carbonate corrosiveness diminishes due to increased mixing of AAIW and UNADW. The close relationship between LDX values and aragonite contents in the sediments shows much promise for the quantification of the aragonite loss under the influence of different water masses. LDX failure and uncertainties may be attributed to (1) aragonite dissolution due to bottom water corrosiveness, (2) aragonite dissolution due to additional CO2 release into the bottom water by the degradation of organic matter based on an enhanced supply of organic matter into the sediment, (3) variations in the distribution of L. inflata and hence a lack of supply into the sediment, (4) dilution of the sediments and hence a lack of tests of L. inflata, or (5) redeposition of sediment particles.
