Addressing non-communicable diseases in the Seychelles: towards a comprehensive plan of action.

This article reviews the different steps taken during the past 20 years for the prevention and control of non-communicable diseases (NCDs) in the Seychelles. National surveys revealed high levels of several cardiovascular risk factors and prompted an organized response, starting with the creation of an NCD unit in the Ministry of Health. Information campaigns and nationwide activities raised awareness and rallied increasingly broad and high-level support. Significant policy was developed including comprehensive tobacco legislation and a School Nutrition Policy that bans soft drinks in schools. NCD guidelines were developed and specialized 'NCD nurses' were trained to complement doctors in district health centers. Decreasing smoking prevalence is evidence of success, but the raising so-called diabesity epidemic calls for an integrated multi-sector policy to mould an environment conducive to healthy behaviors. Essential components of these efforts include: effective surveillance mechanisms supplemented by focused research; generating broad interest and consensus; mobilizing leadership and commitment at all levels; involving local and international expertise; building on existing efforts; and seeking integrated, multi-disciplinary and multi-sector approaches.

Advances in the pharmacological treatment of gastro-oesophageal cancer.

Despite a sharp decline in the incidence of gastric cancer during the second half of the 20th century, this malignancy remains the second leading cause of cancer mortality in the world. The incidence and mortality rate of gastric cancer increase with age; at present, the median ages at diagnosis are 67 years for men and 72 years for women in the US. This article reviews and discusses current medical treatment options for both the general population and elderly gastric cancer patients. Management of localized gastric cancer has changed significantly over recent years. Adjuvant chemoradiation is not generally recommended outside the US. After decades of trials of adjuvant chemotherapy with inconclusive results, a significant survival benefit for perioperative combination chemotherapy - as compared with surgery alone - in patients with resectable or locally advanced gastro-oesophageal cancer was recently demonstrated in the UK MAGIC trial. A further large, randomized trial from Japan demonstrated a significant survival benefit for adjuvant chemotherapy with S-1 after D2 resection for gastric cancer. However, both trials are applicable only to the population in which the trials were conducted. Specific data on elderly patients are missing. For patients with metastatic disease, oral fluoropyrimidines, such as capecitabine, have been developed. In Asian patients, treatment with the oral fluoropyrimidine S-1 is safe and effective. Docetaxel, oxaliplatin and irinotecan have demonstrated activity against gastric cancer in appropriately designed, randomized, phase III trials and have increased the available treatment options significantly. In addition, according to preliminary data, trastuzumab in combination with chemotherapy has significantly improved activity when compared to chemotherapy alone in patients with human epidermal receptor (HER)-2-positive gastric and gastro-oesophageal cancers. Thus, therapeutic decisions in patients with advanced gastric cancer may be adapted to the molecular subtype and co-morbidities of the individual patient. Data from retrospective analyses suggest that oxaliplatin seems to be better tolerated than cisplatin in elderly patients.

Cinema and the Work of Doré

According to Ray Harryhausen, a special effects expert in the film industry, "Gustave Doré would have made a great director of photography . . . He saw things from the point of view of the camera." Doré's work has had a permanent impact on the imaginative realm of film since its very early days. In return, the silver screen has etched Doré into the 20th century imagination. Almost every film about the Bible since The Life and Passion of Jesus Christ produced by Pathé in 1902 refers to his illustrations, and every film adaptation of Dante or Don Quixote has used him as a model, from Georg Wilhelm Pabst and Orson Welles to Terry Gilliam. All films dealing with life in London in the Victorian era by directors ranging from David Lean, to Roman Polanski and Tim Burton draw on the visions in London: a pilgrimage for their sets. A large number of dream fantastical or phantasmagorical scenes take their inspiration from Doré's graphic world, beginning with Georges Méliès' A Trip to the Moon in 1902. In the realm of cartoons and animation, Walt Disney owes a huge debt to Doré. Doré primal forests, from Atala in particular, were also used in the various versions of King Kong from 1933 to the 2005 film by Peter Jackson, who had already drawn on Doré for The Lord of the Rings. Jean Cocteau was also indebted to the illustrations for Perrault's Fairy Tales for his Beauty and the Beast (1945), as was George Lucas for the character Chewbacca in Star Wars (1977) and even the Harry Potter film series. Through his influence on film history, Doré shaped the mass culture imagination.

The hemodynamics of septic shock: a historical perspective.

In the late 19th century, it was already known that severe infections could be associated with cardiovascular collapse, a fact essentially attributed to cardiac failure. A major experimental work in the rabbit, published by Romberg and Pässler in 1899, shifted attention to disturbed peripheral vascular tone as the mechanism of hypotension in these conditions. In the first half of the 20th century, great progresses were made in the pathophysiologic understanding of hemorrhagic and traumatic shocks, while researchers devoted relatively little attention to septic shock. Progress in the hemodynamic understanding of septic shock resumed with the advent of critical care units. The hyperdynamic state was recognized in the late fifties and early sixties. The present short review ends with landmark studies by Max Harry Weil, demonstrating the importance of venous pooling, and John H. Siegel, which introduced the concept of deficient peripheral utilization of oxygen, inspiring later work on the microvascular disturbances of septic shock.

Politique fédérale des agglomérations dans les domaines des transports et de l'urbanisation

La croissance de la population, de l'économie et des transports individuels motorisés, particulièrement depuis la seconde moitié du 20ème siècle, ont notamment comme corollaire le développement urbanistique hors des frontières de la ville-centre et la formation des agglomérations. Ces zones urbaines sont stratégiques puisqu'elles accueillent une part toujours plus importante de la population et représentent le moteur de l'économie nationale. Toutefois, le développement des agglomérations et de la mobilité individuelle motorisée ne va pas sans poser de nombreux problèmes, dont la résolution nécessite de les aborder à l'échelle de l'agglomération, en coordonnant les transports et l'urbanisation. Notre système politique fédéral se définit notamment par une répartition des compétences dans une multitude de domaines entre les trois niveaux institutionnels de la Confédération, des cantons et des communes. Cette réalité est particulièrement vraie en matière d'aménagement du territoire. Il est à noter que les plus petites unités institutionnelles (les communes) conservent encore aujourd'hui des prérogatives importantes dans ce domaine. Au début des années 2000, la Confédération a développé une politique publique en faveur de ces zones stratégiques. Au moyen du fonds d'infrastructure, la politique fédérale des agglomérations dans les domaines des transports et de l'urbanisation est une politique publique incitative. Le dépôt, par les agglomérations, d'un projet respectant un cahier des charges précis et proposant des mesures de coordination entre les transports et l'urbanisation, permet d'obtenir un cofinancement fédéral du transport d'agglomération. Parmi les projets d'agglomération de première génération présentés à la Confédération, certains ont obtenu le cofinancement, d'autres pas. Le dimensionnement trop généreux des surfaces à bâtir fut notamment un facteur d'échec du projet d'agglomération de Fribourg, alors que la capacité à développer l'urbanisation à l'intérieur de l'agglomération fut un facteur de succès du projet Lausanne-Morges. L'analyse des projets d'agglomération Riviera et Monthey-Aigle, qui sont des projets de deuxième génération, confrontée à des entretiens avec des urbanistes et des responsables politiques, permet d'identifier leurs faiblesses et leurs atouts. Le projet d'agglomération Riviera présente une complémentarité des territoires et un grand potentiel de développement, mais aussi un manque de cohésion des partenaires du projet. Quant au projet Monthey-Aigle, il existe une réelle volonté politique de trouver des solutions aux conflits, mais les possibilités de développer les transports publics sont faibles. Dans le cadre de l'examen fédéral de ces deux projets d'agglomération, les éléments précités pourraient être des facteurs d'échec ou de succès. La politique publique fédérale invite les agglomérations à penser le développement de leurs transports et de leur urbanisation à un niveau global. La prise de hauteur et la coordination politique que cela suppose sont à même d'améliorer le lieu de vie des trois-quarts de la population suisse et de préserver le moteur de l'économie nationale. The growth of population, economy and personal motorised transportation, most particularly since the second half of the 20th century, has, as a consequence, induced an expansion of urban areas outside the borders of cities and encouraged the formation of urban agglomerations. These urban zones are of strategic importance as they attract an increasingly large population and represent a real driver of the national economy. However, the development of these agglomerations and the motorised mobility of their inhabitants cause numerous problems which require solutions to be adopted at the level of the agglomeration involving the interconnection of transport and urbanisation. Our federal political system is characterised by a distribution of responsibilities in many domains among the three institutional levels, namely the Confederation, the cantons and the communes. This is particularly the case of territorial developments. It should be noted that the smallest institutional units, the communes, still hold today important responsibilities in this area. At the beginning of the years 2000, the Confederation has developed a public policy in favour of these strategic zones. Through the establishment of an infrastructure fund, the federal policy in favour of urban agglomerations in the areas of transport and urbanisation aims at providing incentives to agglomerations. The submission by the agglomeration of a project containing a clear description of tasks and measures to integrate transport and urbanisation can result in a cofinancing participation by the Confederation in this project. Among the projects of first generation which had been submitted to the Confederation, some have received the cofinancing, others have not. The too generous dimension of the building areas in the project submitted by the agglomeration of Fribourg was a factor of its failure, while the capacity to develop urbanisation within the agglomeration was a factor of success for the Lausanne-Morges project. The analysis of the projects of the agglomerations Riviera and Monthey-Aigle which are projects of the second generation, as well as the interviews of urbanists and concerned officials have allowed us to identify their strengths and weaknesses. The Riviera project provides a complementary approach and a high potential of territorial developments, but at the same time denotes a lack of cohesion among partners of the project. With respect to the project Monthey-Aigle, there is a real political willingness to resolve conflicts, but the potential for the development of public transports is small. In the consideration by the Confederation of these two projects, the factors mentioned above may bring success or failure. The federal public policy incites the agglomerations to conceive the development of their transportation and urbanisation plans at a global level. The elevation of interests and the political coordination that this requires can improve the place of living of ¾ of the Swiss population and preserve the engine of growth of the national economy.

European climate variations over the past half-millennium reconstructed from groundwater

Temperature reconstructions for recent centuries are the basis of estimations of the natural variability in the climate system before and during the onset of anthropogenic perturbation. Here we present, for the first time, an independent and physically based reconstruction of mean annual temperature over the past half millennium obtained from groundwater in France. The reconstructed noble gas temperature (NGT) record suggests cooler than present climate conditions throughout the 16th-19th centuries. Periods of warming occur in the 17th-18th and 20th century, while cooling is reconstructed in the 19th century. A noticeable coincidence with other temperature records is demonstrated. Deuterium excess varies in parallel with the NGT, and indicates variation in the seasonality of the aquifer recharge; whereas high excess air in groundwater indicates periods with high oscillations of the water table.

Flore alpine et réchauffement climatique: observation de trois sommets valaisans à travers le XXe siècle

Alpine flora and climate change: monitoring of three summits in Valais (Switzerland) during the 20th century Climate change might trigger an upward shift of the flora in the Swiss Alps, especially since these experienced higher change in average than observed on a global scale. Previous investigations in the canton des Grisons (Switzerland) and Austria have revealed an increase of floristic diversity on alpine summits since the beginning of the 20th century. Three summits in Valais were revisited in this study: the Gornergrat (first inventory in 1919), the Torrenthorn (about in 1885) and the Beaufort (about in 1920). Every summit was newly inventoried in 2003 in the framework of the PERMANENT.PLOT.CH project. All showed a strong increase in species richness. On the Gornergrat (3135 m), 16 species were not found anymore, but 35 new ones were observed. The number of species on this exceptionally rich summit rose from 102 to 121. In comparison, the floristic richness increased from 24 to 63 species on the Torrenthorn (2924 m) and from 16 to 48 species on the Beaufort (3048 m). As in previous studies, this increase seems likely to be associated with climate change: the new species prefer, in average, higher temperature conditions than those previously prevailing on the summits. On the Gornergrat and Beaufort, our observations reveal a development of alpine meadows, whereas species typical of rocks and raw soils are predominantly colonising the Torrenthorn. This difference might be related to the important damage caused by wanderers on the vegetation of the Torrenthorn.
