Développement psychomoteur des enfants nés prématurément avec retard de croissance

La grande prématurité, soit une naissance avant 32/40 semaines de gestation, concerne 1% des enfants en Suisse. L'avenir développemental de ces enfants prématurés est influencé pai" des facteurs présents avant la naissance, durant le séjour néonatal, puis par l'environnement. Certains enfants, à terme ou prématurés, naissent avec un poids trop petit pour l'âge gestationnel (Retard de Croissance Intra-utérin, RCIU). Chez les enfants nés à terme, les recherches montrent que cet élément est associé à des troubles du comportement, et notamment une hyperactivité. Chez l'enfant grand prématuré, les résultats sont plus mitigés, certaines études montrent plus de déficiences cognitives, d'autres plus d'hyperactivité, et finalement d'autres aucune séquelle. L'objectif de cette analyse rétrospective était donc d'évaluer l'impact, dans une cohorte d'enfants prématurés nés entre 2000 et 2005, du RCIU sur les scores cognitifs, le risque de déficience motrice, visuelle ou auditive, et le comportement. Durant cette période, 523 patients nés avant 32 semaines de gestation ont été hospitalisés dans notre centre tertiaire, dont 450 ont survécu et 343 (76%) ont été évalués à l'âge de 5 ans. L'évaluation à 5 ans comprenait une anamnèse, un examen neurologique détaillé, une évaluation cognitive au moyen d'un test standardisé, le K-ABC, et un questionnaire de dépistage des troubles du comportement (Strengths and Difficulties Questionnaire). Les analyses de régression ont montré l'absence d'association entre le petit poids de naissance et les score cognitifs, le risque de déficience neuro dé veloppementale (retard mental, paralysie cérébrale, cécité ou surdité), ou l'utilisation de thérapies. Par contre, comme chez les enfants nés à terme, cet élément était significativement associé au comportement hyperactif. Les facteurs néonataux associés au score cognitif dans l'analyse multi variée étaient l'âge gestationnel, le niveau socio-économique et les lésions cérébrales majeures. Le risque de déficience était influencé par l'âge gestationnel, les lésions cérébrales, la consommation de tabac durant la grossesse et l'asphyxie néonatale (pH< 7.0 et encéphalopathie). La présence de lésions cérébrales majeures était associée à l'utilisation de plusieurs thérapies, alors que 1 utilisation d'une seule thérapie était associée à l'âge gestationnel, à la présence d'une entérocolite nécrosante, ou d'une asphyxie néonatale. Conclusion : Dans notre cohorte, le petits poids de naissance chez les enfants grands prématurés n'était associé qu'au comportement hyperactif, et à aucune autre séquelle neurodeveloppementale. Pour mieux définir l'impact du RCIU chez les grands prématurés, des etudes complémentaires, permettant de distinguer les patients avec petit poids constitutionnel de ceux avec retard de croissance, sont nécessaires.

Prevalence of ragweed allergy in rural Geneva - a pilot study.

OBJECTIVE: The prevalence of ragweed allergy is increasing worldwide. Ragweed distribution and abundance is spreading in Europe in a wide area ranging from the Rhone valley in France to Hungary and Ukraine, where the rate of the prevalence can peak at as high as 12%. Low-grade ragweed colonisation was seen in Geneva and Ticino, less than two decades ago. There were fears that allergies to ragweed would increase Switzerland. The intent of this study was to assess the rate of prevalence of sensitisation and allergy to ragweed in the population living in the first rural Swiss setting where ragweed had been identified in 1996, and to evaluate indirectly the efficacy of elimination and containment strategies. MATERIAL AND METHODS: In 2009, 35 adults in a rural village in the Canton of Geneva were recruited. Data were collected by means of questionnaires and skin-prick tests were done on each participant. The study was approved by the local Ethics Committee. RESULTS: Based on questionnaires, 48.6% had rhinitis (95% confidence interval [CI] 32.9-64.4; n = 17/35) and 17.1% asthma (95% CI 8.1-32.6; n = 6/35). Atopy was diagnosed in 26.4% (95% CI 12.9-44.4) of the sample (n = 9/34). Ragweed sensitisation was found in 2.9% (95% CI 0.7-19.7; n = 1/34), mugwort sensitisation in 2.9% (95% CI 0.1-14.9; n = 1/35), alder sensitisation in 17.1% (95% CI 6.6-33.6; n = 6/35), ash sensitisation in 12.5% (95% CI 3.5-29.0; n = 4/32) and grass sensitisation in 22.9% (95% CI 10.4-40.1; n = 8/35). Ragweed (95% CI 0.1-14.9; n = 1/34) and mugwort allergies (95% CI 0.1-14.9; n = 1/35) were both found in 2.9% of the population. CONCLUSION: This study showed a surprisingly low incidence of ragweed sensitisation and allergy, of 2.9% and 2.9%, respectively, 20 years after the first ragweed detection in Geneva. The feared rise in ragweed allergy seems not to have happened in Switzerland, compared with other ragweed colonised countries. These results strongly support early field strategies against ragweed.

Transgression et initiation : tendances idéologiques et développement littéraire du récit de Genèse 2-3

Several questions about the story of Gen 2-3 remain unresolved in current scholarship. For instance, the implications and manifold consequences of the transgression act - the consumption of the forbidden fruit - are much debated. Interpreters generally agree that the story is connected to several "J" / "non-P" narratives of the primeval history. Besides the use of the tetragrammaton as the designation for God, a common characteristic of these stories is the strong opposition between Yhwh as a harsh deity on one hand and disobedient and transgressing humankind on the other. This paper reconsiders several open questions as well as the aforementioned consensus. The analysis of important motifs in Gen 2-3 leads to the conclusion that this story differs in theologically important ways from the postulated "J"-narrative in Genesis. This indicates that it was not composed as an integral part of that narrative. There are, in Gen 2-3, ideological features and linguistic elements typical of the "J" stratum, but they are all found in the sections that present Yhwh God's investigation and punishment of the couple (3,8-19.24). Since these verses are in tension with or even contradict their immediate context, it should be assigned to a redactional ("J") layer. According to this analysis, the transgression in Gen 2-3 should not be considered a sin. Rather, it is an important step in human evolution towards a self-conscious and autonomous being. The plot has a structure similar to some episodes in ancient Near Eastern myths. 'Initiation' functions as a central theme. Finally, the article discusses the literary milieu of the story. Because of several linguistic and thematic similarities with Gen 1, with P-texts in general, and with the book of Ezekiel, the relationship of Gen 2-3 to these literary entities needs to be reconsidered.

Anivellació d'una plataforma elevadora en l'entorn rural

L’objectiu d’aquest projecte és redissenyar la plataforma de la màquina elevadora DamconCMBB per tal que, el mateix operari pugui anivellar-la en funció del desnivell del terreny. Almateix temps i a conseqüència d’això, es busca que l’usuari millori en comoditat i enidoneïtat de l’entorn de treball. És a dir que, el fet de poder anivellar la plataforma puguievitar treballar en posicions forçades i prevenir d’aquesta manera riscos innecessaris ipossibles lesions dels operaris.En primer lloc, es vol conservar tota l’estructura que sigui possible i fabricar una novaplataforma que es pugui anivellar en sentit longitudinal i transversal.En segon lloc, l’acció d’anivellació l’haurà de practicar manualment l’operari a través d’undistribuïdor hidràulic. En tercer lloc, l’alçada que assolirà la plataforma de la màquina autoportant i autopropulsada serà de 2 metres respecte el terra. Per acabar, l’anivellació només la podrà efectuar l’operari tot utilitzant un comandamentmanual. Així és que, la modificació a practicar a la màquina no inclou un sistemad’autoanivellació, així com, també queda obert l’apartat de disseny industrial, ja que tampocés una de les prioritats d’aquest projecte

The situation of rural women in Spain: the case of small-scale artisan food producers

La discriminación de las mujeres rurales y la falta de una aplicación efectiva de la legislación sobre la igualdad de género es un fenómeno extendido alrededor del mundo. Las mujeres han sido tradicionalmente las responsables del cuidado y alimentación familiar, en consecuencia han desarrollado tareas productivas que facilitan la combinación de actividades productivas y reproductivas en la explotación agraria. La transformación alimentaria es una de esas actividades que permite a las mujeres tener un trabajo remunerado o complementar la renta agraria en un contexto dónde la mayoría de los trabajos agrícolas están vetados para ellas. Sin embargo, las mujeres suelen estar vinculadas a proyectos que priorizan la producción local y de calidad, y la expansión de la producción industrial de alimentos ha empeorado la situación de las mujeres artesanas alimentarias. En el presente estudio se pretende, mediante el uso de metodologías cualitativas, abordar un diagnóstico de la situación de las mujeres que llevan a cabo proyectos de transformación alimentaria a pequeña escala en España mostrando sus principales dificultades, necesidades y propuestas.

Una experiència d'atenció a la gent gran en una zona rural

El fenomen del progressiu envelliment de la població, a causa sobretot de l’allargament de l'esperança de vida i la baixa natalitat, fa que algunes de les principals preocupacions de les famílies, de les entitats cíviques i de les autoritats públiques estiguin relacionades amb les condicions de vida de la gent gran. Aquesta preocupació es justifica, a més, per la necessitat de reconèixer la molta i bona feina feta per una generació que ha viscut temps difícils i ha lluitat per salvaguardar la nostra cultura i per millorar les condicions econòmiques i socials del país. La investigació que presentem s'adreça a fer front als aspectes esmentats en una zona rural de l’AIt Empordà amb pocs recursos propers, on el model urbá d'atenció no encaixa i on no hi ha Instruments de coordinació. El projecte va néixer de la mateixa comunitat, a través del Consell Pastoral Interparroquial de les parròquies de Garriguella, Rabós d'Empordà i Vilamaniscle i deis ajuntaments dels esmentats municipis

Transformation of a Rural Landscape in the Eastern Pyrenees Between 1953 and 2000

In the mid-20th century, the southern parts of the Madres and Mont Coronat massif (Eastern Pyrenees, France) were characterized by a Mediterranean landscape shaped by human activity. Long-term use of these mountains for crops, livestock, and forestry led to an increase in grassland areas at the expense of forest. However, socioeconomic transformation (abandonment of agriculture and a decrease in the rural population) in recent decades has caused profound changes in this massif. Interpretation of aerial photographs (1953, 1969, 1988, and 2000) made it possible to detect and analyze the changes produced in the study area (6787 ha) during this period. In 1953 most of the massif landscape consisted of grasslands (38%) and open forests (18%), with some areas of dense forest (15%). By 2000, dense forest cover had doubled in size (31%), and grassland had decreased considerably (by 73% of the initial area). Since 1953, the study area has become more homogeneous, with a few local exceptions. The results of this study suggest that socioeconomic factors might be the main cause of landscape transformations in this period of approximately 50 years.

Distribution Patterns of Soil Properties in a Rural Mediterranean Area in Northeastern Spain

Soil properties on the Cap de Creus Peninsula, NE Spain depend primarily on scarce agricultural practices and early abandonment. In the study area, 90% of which is mainly covered by Cistus shrubs, 8 environments representing variations in land use/land cover and soil properties at different depths were identified. In each environment variously vegetated areas were selected and sampled. The soils, collected at different depths, were classified as Lithic Xerorthents according to the United States Department of Agriculture system of soil classification (USDA-NRCS 1975). Differences in soil properties were largely found according to the evolution of the plant canopy and the land use history. To identify underlying patterns in soil properties related to environmental evolution, factor analysis was performed and factor scores were used to determine how the factor patterns varied between soil variables, soil depths and selected environments. The three-factor model always accounted for 80% of the total variation in the data at the different soil depths. Organic matter was the more relevant soil property at 0–2 cm depth, whereas active minerals (silt and clay) were found to be the most relevant soil parameters controlling soil dynamics at the other depths investigated. Results showed that vineyards and olive tree soils are poorly developed and present worse conditions for mineral and organic compounds. Analysis of factor scores allowed independent assessment of soils, depth and plant cover and demonstrated that soils present the best physico-chemical characteristics under Erica arborea and meadows. In contrast, soils under Cistus monspeliensis were less nutrient rich and less well structured

Investigation of the occurrence of pesticide residues in rural wells and surface water following application to tobacco

In this work the exposure of wells and surface water to pesticides, commonly used for tobacco cropping, was assessed. Water consumption wells and surface water flows were sampled at different times. After a preconcentration step with solid phase extraction (SPE), the selected pesticides were determined by gas chromatography with electron capture detection (GC-ECD) or high performance liquid chromatography with diode array detection (HPLC-DAD). No pesticides were detected in the well water samples and surface water flow in the winter season. However, in the spring and summer higher concentrations of chlorpyrifos and imidacloprid were found in the water source samples. Atrazine, simazine and clomazone were also found. The occurrence of pesticides in collected water samples was related with the application to tobacco.
