Composición de ácidos grasos de los caprélidos (Crustacea: Amphipoda) del estrecho de Gibraltar

The total fatty acid composition of nine species of caprellidean amphipods collected from the Strait of Gibraltar was investigated. All caprellids were characterised by high levels of polyunsaturated fatty acids, mainly eicosapentaenoic acid, 20:5(n-3), and docosahexaenoic acid, 22:6(n-3); other major fatty acids were the saturate palmitic acid, 16:0, and the monounsaturate oleic acid, 18:1(n-9). In spite of this general uniformity, univariate and multivariate analysis showed that Caprella acanthifera and C. grandimana differed from the remaining species ( C. danilevskii , C. equilibra , C. liparotensis , C. penantis , C. santosrosai , Phtisica marina and Pseudoprotella phasma ). These two species ( C. acanthifera and C. grandi- mana ) showed higher concentrations of 18:1(n-7) and 20:4(n-6) and lower percentages of 22:6(n-3). These results, together with higher values of the biomarker ratio 20:5(n-3)/22:6(n-3) and a lower ratio 18:1(n-9)/18:1(n-7), suggested a greater contribution of diatoms and macroalgae in the diet of C. acanthifera and C. grandimana and a lesser contribution of flagellates than in the remaining species. The cluster classification of the caprellid specimens from the Strait of Gibraltar based on the fatty acid composition was in agreement with the Cluster output from data of feeding behaviour. Sex-related changes in the fatty acid composition were also explored in C. acanthifera , C. danilevskii and C. penantis ; the percentage of 18:0, 20:4(n-6), and 20:5(n-3) was significantly higher in males, whereas 16:1(n-7) was higher in females. The intraspecific diferences of fatty acids in different environmental conditions seem to indicate that the consumption of diatoms in contrast to flagellates increases with the degree of eutrophication.Se estudió la composición de ácidos grasos de nueve especies de anfípodos caprélidos recolectados en el Estrecho de Gibraltar. Todos los caprélidos se caracterizaron por presentar niveles elevados de ácidos grasos poliinsaturados, principal- mente eicosapentaenoico, 20:5(n-3), y docosahexaenoico, 22:6(n-3); otros ácidos grasos importantes fueron el saturado ácido palmítico, 16:0, y el monoinsaturado ácido oleico, 18:1(n-9). A pesar de este patrón general, los análisis univariantes y multivariantes mostraron que, atendiendo a la composición de ácidos grasos, Caprella acanthifera y C. grandimana se diferenciaron significativamente de las especies restantes ( C. danilevskii , C. equilibra , C. liparotensis , C. penantis , C. santosrosai , Phtisica marina y Pseudoprotella phasma ). Estas dos especies ( C. acanthifera y C. grandimana ) mostraron por- centajes más altos de 18:1(n-7) y 20:4(n-6) y más bajos de 22:6(n-3). Estos resultados, junto con valores más altos del bio- marcador 20:5(n-3)/22:6(n-3) y más bajos del 18:1(n-9)/18:1(n-7) sugieren una mayor contribución de diatomeas y macroalgas en la dieta de C. acanthifera y C. grandimana y una menor contribución de flagelados. El dendrograma de clasificación de los caprélidos del Estrecho de Gibraltar basado en la composición de ácidos grasos fue similar al obtenido a partir de los datos de comportamiento alimenticio de las especies. Los cambios en la composición de ácidos grasos con respecto al sexo fueron explorados en C. acanthifera , C. danilevskii y C. penantis ; el porcentaje de 18:00, 20:4(n-6), y 20:5(n-3) fue significativamente superior en machos, mientras que el de 16:1(n-7) fue superior en las hembras. Las diferencias intraespecíficas en la composición de ácidos grasos en diferentes condiciones ambientales parecen indicar que el consumo de diatomeas frente al de dinoflagelados se incrementa al aumentar el grado de eutrofización

Psychosocial Variables and Healthcare Resources in Patients with Fibromyalgia, Migraine and Comorbid Fibromyalgia and Migraine: A Cross-Sectional Study

Fibromyalgia and migraine frequently coexist. We aimed to compare the burden caused by fibromyalgia (FM), migraine (M) and comorbid fibromyalgia and migraine (FM + M) by assessing psychosocial variables and the use of healthcare resources. A survey was posted to the websites of different patients' associations. It included sociodemographic data, the Patient Health Questionnaire-9, the Insomnia Severity Index, the EuroQOL-5D-5L and a questionnaire evaluating the use of healthcare resources during the past six months. In total, 139 FM patients, 169 M patients and 148 FM + M patients participated in the survey. Mean depression and insomnia scores were clinically relevant in every group and significantly higher in FM + M (16.3 +/- 5.4 for depression, 18.5 +/- 5.6 for insomnia) than in FM (14.3 +/- 5.7 for depression, 16.8 +/- 5.5 for insomnia) or M (11.7 +/- 5.4 for depression, 13.1 +/- 5.9 for depression), where p < 0.001 in both cases. Suicidal ideation was frequent in every group, but significantly more frequent in FM + M (63% vs. 45% in FM and 35% in M; p < 0.001). EQ-5D-5L (0.656 +/- 0.1 in FM + M, 0.674 +/- 0.1 in FM, 0.827 +/- 0.1 in M, p < 0.001) and EQ-5D-5L VAS scores (38.2 +/- 21.9 in FM + M, 45.6 +/- 21.8 in FM, 63.5 +/- 23.7 in M, p < 0.00) were lower than the reported mean population values and the lowest in FM + M. FM and FM + M used more healthcare resources than M. It is concluded that the psychosocial burden was high in the three samples. FM and FM + M had a more relevant impact on patients' wellbeing and required more medical attention than M. The burden caused by FM + M was higher than in both individual diseases

Les pratiques alimentaires d’hommes ouest-africains vivant en Île-de-France

En France, les migrants originaires d’Afrique de l’Ouest adoptent, selon leur âge et leurs parcours, différents types d’organisation sociale. Du foyer à l’hôtel meublé en passant par le squat ou l’appartement, ils sont amenés à redéfinir les règles de leur vivre ensemble. L’alimentation et sa gestion collective traditionnelle offrent un prisme particulièrement efficace pour révéler les stratégies qui conduisent les migrants, seuls ou en groupe, à renouveler ou à rompre avec les modes de vie solidaires hérités de leur culture d’origine

Sports video: Fine-grained action detection and classification of table tennis strokes from videos for MediaEval 2021

This paper presents the baseline method proposed for the Sports Video task part of the MediaEval 2021 benchmark. This task proposes a stroke detection and a stroke classification subtasks. This baseline addresses both subtasks. The spatio-temporal CNN architecture and the training process of the model are tailored according to the addressed subtask. The method has the purpose of helping the participants to solve the task and is not meant to reach stateof-the-art performance. Still, for the detection task, the baseline is performing better than the other participants, which stresses the difficulty of such a task
