Typologie des bilans céréaliers des pays du monde

[eng] The observation of to day's levels and of long run trends of self supply rates and overall per capita consumption of grains (cereals) in all countries contributes to the world food situation analysis. The changes put into evidence provide a many-sided image, far from the early 1970's catastrophism, but showing deep shortages and desequili- briums. The world is better off to day, food wise, but there is still much to do. [fre] L'examen du niveau actuel et de l'évolution sur longue période des taux d'auto-approvisionnement et de la consommation apparente par habitant en céréales de tous les pays contribue à préciser le constat relatif aux changements dans la situation alimentaire mondiale. Il en résulte une image nuancée, éloignée du catastrophisme du début des années 1970, mais révélant des insuffisances et des déséquilibres manifestes et problématiques. Le monde peut sans doute se nourrir ; il ne le fait pas encore.

Les prix agricoles et leur évolution différenciée dans chaque pays se justifient-ils économiquement ?

[fre] Le système des parités vertes suscite des positions diverses. La question essentielle est de savoir si l'évolution différenciée des prix dans chaque pays de la Communauté se justifie-t-elle économiquement. La réponse apportée est oui théoriquement, si les agriculteurs évoluent dans des économies différentes. Ceci étant dit, l'évolution différenciée des prix agricoles constatée entre un certain nombre de pays de la Communauté a engendré des avantages (ou désavantages) économiques entre Etats-membres du fait d'une mauvaise gestion du système des parités vertes. L'analyse a été réalisée en comparant les évolutions entre l'Allemagne, la Grande-Bretagne, l'Italie, et la France pour quelques produits. [eng] The green parity system, which was widely criticized in France, defended by a number of other countries and considered neutral by the Commission, caused such a variety of reactions that this alone was reason enough to look into the matter more deeply. Our main concern was to establish whether there is any real economic justification for the differential development of prices in agriculture which the introduction of green rates has brought about within the different Common Market countries. The answer would seem to be yes, in theory, as long as agriculture is developing in a different economy in each country. Having said this, however, the differential development of agricultural prices from one country to another within the Community has put certain member states at an economic advantage and others at a disadvantage because of poor management of the green parity system. The analysis was carried out by comparing trends in selected products in Germany, Great Britain, Italy, the Netherlands and France.

Prevalence of sleep-disordered breathing in a 316-patient French cohort of stable congestive heart failure.

International audienceBACKGROUND: Heart failure with systolic dysfunction occurs frequently. Studies in North America and Germany have shown a high prevalence of sleep-disordered breathing in patients with heart failure. AIMS: To assess the prevalence of sleep-disordered breathing and its associated risk factors in French patients with heart failure. METHODS: A total of 316patients with stable heart failure and a left ventricular ejection fraction less or equal to 45% underwent polygraphy prospectively to diagnose sleep apnoea syndrome, defined as an apnoea-hypopnoea index greater or equal to 10events/h. RESULTS: Mean age, left ventricular ejection fraction, and body mass index were 59+/-13years, 30+/-11% and 28+/-6kg/m(2), respectively. The prevalence of sleep breathing disorder was 81% (n=256); 30% of syndromes were classified as central and 70% as obstructive. The mean apnoea-hypopnoea index was high (30+/-3events/h) and a large proportion (41%) of syndromes had an apnoea-hypopnoea index greater or equal to 30events/h. A central sleep apnoea syndrome pattern was associated with more severe heart failure and a more elevated apnoea-hypopnoea index than an obstructive pattern. The prevalence of sleep-disordered breathing was lower in women than in men (64% versus 85%; chi(2)=0.0003) as was its severity (mean apnoea-hypopnoea index 15+/-13events/h versus 27+/-19events/h, p=0.0001). CONCLUSION: The prevalence of sleep-disordered breathing was high in a French heart failure population, with most syndromes having an obstructive pattern. Prevalence and severity were higher in men than in women
