Soil quality assessment through a multi-approach analysis in soils of abandoned terraced land in NE Spain

The abandonment of agricultural land in mountainous areas has been an outstanding problem along the last century and has captured the attention of scientists, technicians and administrations, for the dramatic consequences sometimes occurred due to soil instability, steep slopes, rainfall regimes and wildfires. Hidromorfological and pedological alterations causing exceptional floods and accelerated erosion processes has therefore been studied, identifying the cause in the loss of landscape heterogeneity. Through the disappearance of agricultural works and drainage maintenance, slope stability has resulted severely affected. The mechanization of agriculture has caused the displacement of vines, olives and corks trees cultivation in terraced areas along the Mediterranean catchment towards more economically suitable areas. On the one hand, land use and management changes have implicated sociological changes as well, transforming areas inhabited by agricultural communities into deserted areas where the colonization of disorganized spontaneous vegetation has buried a valuable rural patrimony. On the other hand, lacking of planning and management of the abandoned areas has produced badlands and infertile soils due to wildfire and high erosion rates strongly degrading the whole ecosystems. In other cases, after land abandonment a process of soil regeneration has been recorded. Investigations have been conducted in a part of NE Spain where extended areas of terraced soils previously cultivated have been abandoned in the last century. The selected environments were semi-abandoned vineyards, semi-abandoned olive groves, abandoned stands of cork trees, abandoned stands of pine trees, scrubland of Cistaceaea, scrubland of Ericaceaea, and pasture. The research work was focused on the study of most relevant physical, chemical and biological soil properties, as well as runoff and erosion under soils with different plant cover to establish the abandonment effect on soil quality, due to the peculiarity and vulnerability of these soils with a much reduced depth. The period of observation was carried out from autumn 2009 to autumn 2010. The sediment concentration of soil erosion under vines was recorded as 34.52 g/l while under pasture it was 4.66 g/l. In addition, the soil under vines showed the least amount of organic matter, which was 12 times lower than all other soil environments. The carbon dioxide (CO2) and total glomalin (TG) ratio to soil organic carbon (SOC) in this soil was 0.11 and 0.31 respectively. However, the soil under pasture contained a higher amount of organic matter and showed that the CO2 and TG ratio to SOC was 0.02 and 0.11 respectively indicating that the soil under pasture better preserves the soil carbon pool. A similar trend was found in the intermediate soils in the sequence of land use change and abandonment. Soil structural stability increased in the two soil fractions investigated (0.25-2.00 mm, 2.0-5.6 mm) especially in those soils that did not undergo periodical perturbations like wildfires. Soil quality indexes were obtained by using relevant physical and chemical soil parameters. Factor analysis carried out to study the relationship between all soil parameters allowed to related variables and environments and identify those areas that better contribute to soil quality towards others that may need more attention to avoid further degradation processes

Presencia de la icnoespecie Dactyloidites Ottoi en el complejo de abanico costero de Sant Llorenç del Munt (Eoceno, Cuenca del Ebro, NE de España).

The presence of Dactyloidites ottoi is first recorded in the Eocene Sant Llorenç del Munt fan-delta complex. This constitutes the first citation for the Paleogene. The ichnospecies occurs in the lower part of a prograding fan-delta front sequence, associated to other traces produced by sediment-feeders. This association is substituted in the upper part of the sequence by abundant vertical Ophiomorpha indicating an increase of energetic conditions. The paleoenvironmental setting interpreted for Dactyloidites is consistent with that of previous described occurrences.

An active zone characterized by slow normal faults, the northwestern margin of the València trough (NE Iberia): a review

The northwestern margin of the Valencia trough is an area of low strain characterized by slow normal faults and low to moderate seismicity. Since the mid 1990s this area has been the subject of a number of studies on active tectonic which have proposed different approaches to the location of active faults and to the calculation of the parameters that describe their seismic cycle. Fifty-six active faults have been found and a classification has been made in accordance with their characteristics: a) faults with clear evidence of large paleo-, historic or instrumental earthquakes (2/56); b) faults with evidence of accumulated activity during the Plio-Quaternary and with associated instrumental seismicity (7/56); c) faults with evidence of accumulated activity during the Plio-Quaternary and without associated instrumental seismicity (17/56); d) faults with associated instrumental seismicity and without evidence of accumulated activity during the Plio-Quaternary (30/56), and e) faults without evidence of activity or inactive faults. The parameters that describe the seismic cycle of these faults have been evaluated by different methods that use the geological data obtained for each fault except when paleoseismological studies were available. This classification can be applied to other areas with low slip faults because of the simplicity of the approaches adopted. This study reviews the different approaches proposed and describes the active faults located, highlighting the need a) to better understand active faults in slow strain zones through paleoseismological studies, and b) to include them in seismic hazard studies.

Intoxication aiguë au baclofène. Particularités et principes thérapeutiques

En raison de sa prescription croissante pour des indications d'aide à la réduction des consommations ou au maintien de l'abstinence à l'alcool, le risque d'intoxication volontaire ou accidentelle au baclofène s'accroît et favorise l'admission aux urgences ou en réanimation de comas profonds. La difficulté diagnostique repose sur une relative méconnaissance de cette substance et sur le fait que le baclofène ne fait pas partie des substances mises en évidence par les examens toxicologiques de dépistage habituels. La modification de la pharmaco- cinétique du baclofène en cas de surdosage expose le patient à un coma prolongé, nécessitant dès lors un soutien ventilatoire de longue durée. De manière paradoxale, le baclofène expose également à un risque potentiel de convulsions. En cas de prise en charge adéquate, le pronostic est excellent dans la majorité des cas. En partant d'un cas clinique illustratif et d'une revue de littérature, nous proposons une synthèse des principes de prise en charge d'une intoxication aiguë au baclofène. Baclofen is widely used for the treatment of neurological spastic syndromes and has been recently proposed for the treatment of alcohol dependence. The risk of accidental or self- intoxication with baclofen may therefore increase in the future. Baclofen overdose affects the autonomic nervous system and produces an inhibitory effect on the central nervous system. The classic clinical presentation involves prolonged impaired consciousness or coma and neurovegetative symptoms. Paradoxically, baclofen overdose may also promote the occurrence of seizures. The emergency management is mainly supportive and, in the majority of cases, the prognosis appears excellent. Herein we report a case of baclofen self-intoxication and review the literature regarding the toxicity of baclofen, the clinical presentation of an acute baclofen poisoning and the related principles of management.

Abstract: Literature review on organizational culture theories: what they are and how they have been discussed in international and Finnish scientific journals

Les maladies rénales chroniques ne sont pas toutes silencieuses [Chronic kidney diseases do not always pass unnoticed].

Kidney diseases are frequent, but most of the time, they develop unnoticed. This paucity of symptoms may lead to delayed diagnosis with important consequences on their outcome. Nevertheless, specific systemic signs such as skin lesions, joint pain or electrolytes disturbances may sometimes alert the clinician and direct the diagnosis to an underlying nephropathy. A high awareness of clinicians is warranted to recognize these red flags and diagnose these diseases early, as illustrated by two clinical cases discussed in this article.

La prévention du tabagisme et les facteurs organisationnels en médecine générale: une étude pilote en Suisse romande

Context: Several studies have been carried out to describe how general practitioners (GPs) follow smoking cessation counseling's recommendations and to identify GP-related factors that influence their practice. But limited information exists about practice organization's elements influencing smoking counseling and more generally about prevention activities in primary care (PC) in Switzerland. Objectives: Explore the feasibility of this study. Investigate determinants of PC practices associated with smoking cessation counseling in Switzerland. Explore the GP's attitude towards prevention and the organizational characteristics of PC practices. Design: Pilot Web-based survey in a representative sample of Swiss French speaking GPs. Results : 44 GP's responded; 66% were men; mean age = 57.5 years; 59% were in group practices; 1 GP was currently smoking and 32% were ex-smokers; 57% of GPs found very important to perform health prevention activities. 57% of GPs were trained (>5 hours throughout the career) to provide smoking cessation counseling. 84% of GP's always inquire about smoking status during first consultations, compared to 69% during emergency consultations for respiratory symptoms and only 9% during non-respiratory emergency consultation. Factors positively associated with smoking status inquiring were: young age (<57.5) of GP's for first consultations, rural location and solo practice for emergency consultations. Smoking cessation counseling is systematically provided by 48% of GPs during emergency consultations for respiratory symptoms and by 20% of GPs during follow-up consultations. Factor positively associated with smoking cessation counseling was solo practice. Discussion: In Switzerland, there are missed opportunities to provide smoking cessation counseling, especially in emergency situations, possibly in people who have rarely contacts with the health care system. Despite a small sample, this study showed the potential associations between organizational and GP-related factors and smoking cessation counseling. These findings will be further explored in a national study among 200 GPs' practices.

« En fonction de la prise de Méthadone® maternelle peut-on prévoir l'outcome et l'adaptation néonatale, ainsi que la survenue d'un sevrage néonatal, sa durée et le développement à court terme de l'enfant ? »

Objectif : Abstract Le but de cette étude consiste à étudier un éventuel lien entre le dosage du traitement de substitution par la Méthadone® pendant la grossesse et les issues obstétricales (rupture prématurée des membranes, menace d'accouchement prématuré), ainsi que néonatales (telles que le retard de croissance intrautérin, l'adaptation néonatale, le sevrage néonatal aux opiacés et l'hypoglycémie néonatale). Nous évaluerons également le développement psychomoteur de l'enfant à court terme (jusqu'à 18 mois de vie) via l'échelle de Griffiths. Méthode : Il s'agit d'une étude rétrospective sur 50 femmes enceintes sous Méthadone® suivies au CHUV et ayant accouché entre les années 2000 et 2010, ainsi que sur leurs enfants suivis par l'Unité du Développement du CHUV et évalués moyennant l'échelle du développement psychomoteur appelée Griffiths (il s'agit de 26 enfants entre 6-9 mois et 20 entre 18-19 mois). Pour ce faire, nous avons parcouru les différentes archives du CHUV (informatiques et papiers) dans un premier temps. Ces données ont été ensuite saisies dans un tableau Excel avant d'être analysées via STATA. Résumé des résultats : En fonction du dosage de la Méthadone®, 27% (dose plus faible) à 47 % (dose plus élevée) des femmes de notre collectif accouchent prématurément (p = 0.139). 48 % de leurs nouveau-nés présentent un retard de croissance intra-utérin (RCIU). Ce risque est d'autant plus élevé que la Méthadone est faiblement dosée (p = 0.073). Inversement au RCIU, le risque d'hypoglycémie néonatale croît avec la dose maternelle de Méthadone® (p = 0.148). La survenue du syndrome de sevrage néonatal aux opiacés ainsi que sa durée sont significativement plus importantes lorsque le dosage maternel de Méthadone est élevé (p = 0.022 ; p = 0.0118) ou lors de la prise concomitante de benzodiazépines (p = 0.004 ; p = 0.0129). La prise d'autres substances illicites a elle aussi tendance à prolonger le sevrage (p = 0.065). Entre 6-9 mois de vie, il y a plus de microcéphalie (périmètre crânien inférieur au P10) lorsque les enfants reçoivent une dose plus faible in utéro (p = 0.005). Le développement psychomoteur est quant à lui plus favorable lorsque le traitement de substitution est fortement dosé (p = 0.039) et que l'enfant vit chez sa mère biologique (p = 0.050) ou bénéficie d'un contact maternel régulier (p = 0.008). L'effet du dosage de la Méthadone® (p = 0.683) et du lieu de vie (p = 0.211) sur le développement psychomoteur ont néanmoins tendance à s'estomper entre 18-19 mois de vie. Conclusions : Bien qu'un traitement de substitution par la Méthadone hautement dosé augmente la survenue et la durée du syndrome de sevrage néonatal aux opiacés, il y a maintenant des indices pour un meilleur outcome de l'enfant lorsque la substitution est importante (moins de RCIU, de microcéphalie et un développement psychomoteur plus favorable). A propos de l'issue néonatale, tous les enfants nés de mères toxicodépendantes semblent être à risque d'hypoglycémie néonatale. Implications pratiques : Il serait désormais préférable d'augmenter les doses de substitution des futures mères toxicomanes d'autant plus lorsque celles-ci le réclament et tous leurs enfants devraient bénéficier d'une alimentation précoce et de contrôles glycémiques, même s'ils sont eutrophiques.

Feeding ecology and movements of the Barolo shearwater Puffinus baroli baroli in the Azores, NE Atlantic

Trophic ecology and movements are critical issues for understanding the role of marine predators in food webs and for facing the challenges of their conservation. Seabird foraging ecology has been increasingly studied, but small elusive species, such as those forming the"little shearwater" complex, remain poorly known. We present the first study on the movements and feeding ecology of the Barolo shearwater Puffinus baroli baroli in a colony from the Azores archipelago (NE Atlantic), combining global location-sensing units, stable isotope analyses of feathers (δ13C and δ15N), stomach flushings and data from maximum depth gauges. During the chick-rearing period, parents visited their nests most nights, foraged mainly south of the colony and fed at lower trophic levels than during the non-breeding period. Squid was the most diverse prey (6 families and at least 10 different taxa), but species composition varied considerably between years. Two squid families, Onychoteuthidae and Argonautidae, and the fish family Phycidae accounted for 82.3% of ingested prey by number. On average, maximum dive depths per foraging trip reached 14.8 m (range: 7.9 to 23.1 m). After the breeding period, birds dispersed offshore in all directions and up to 2500 km from the breeding colony, and fed at higher trophic levels. Overall, our results indicate that the Barolo shearwater is a non-migratory shearwater feeding at the lowest trophic level among Macaronesian seabirds, showing both diurnal and nocturnal activity and feeding deeper in the water column, principally on small schooling squid and fish. These traits contrast with those of 3 other Azorean Procellariiformes (Cory"s shearwater Calonectris diomedea, the Madeiran storm-petrel Oceanodroma castro and Monteiro"s storm-petrel O. monteiroi), indicating ecological segregation within the Azorean seabird community.
