Services sans frontières : mondialisation, normalisation et régulation de l'économie des services

Les services pèsent plus de 80 % du PIB des pays de l'OCDE mais à peine plus de 20 % dans leurs échanges internationaux, écart qui s'explique, pour partie, par la difficulté à préconiser des normes internationales de type ISO aux activités du secteur tertiaire. À l'aide d'un riche ensemble d'études de cas, un éclairage sur les entraves à la mondialisation des services, qu'elles soient d'ordre social, économique ou culturel. Unique dans sa thématique, l'ouvrage s'éloigne des analyses conventionnelles sur la mondialisation des marchés et les rapports de puissance interétatiques. En plaçant la problématique des services au coeur du nouveau régime de croissance capitaliste, il met en perspective les polémiques sur la sous-traitance et les délocalisations et ouvre la voie à de nouvelles hypothèses sur les liens entre tertiarisation, internationalisation et normalisation.

Human chorionic gonadotropin in pregnancy and maternal risk of breast cancer.

Full-term pregnancies are associated with long-term reductions in maternal risk of breast cancer, but the biological determinants of the protection are unknown. Experimental observations suggest that human chorionic gonadotropin (hCG), a major hormone of pregnancy, could play a role in this association. A case-control study (242 cases and 450 controls) nested within the Northern Sweden Maternity Cohort included women who had donated a blood sample during the first trimester of a first full-term pregnancy. Total hCG was determined on Immulite 2000 analyzer. Odds ratios (OR) and 95% confidence intervals (CI) were estimated through conditional logistic regression. Maternal breast cancer risk decreased with increasing hCG (upper tertile OR, 0.67; CI, 0.46-0.99), especially for pregnancies before age 25 (upper tertile OR, 0.41; CI, 0.21-0.80). The association diverged according to age at diagnosis: risk was reduced after age 40 (upper tertile OR, 0.60; CI, 0.39-0.91) and seemed to increase before age 40 (upper tertile OR, 1.78; CI, 0.72-4.38). Risk was reduced among those diagnosed 10 years or longer after blood draw (upper tertile OR, 0.60; CI, 0.40-0.90), but not so among those diagnosed within 10 years (upper tertile OR, 4.33; CI, 0.86-21.7). These observations suggest that the association between pregnancy hCG and subsequent maternal risk of breast cancer is modified by age at diagnosis. Although the hormone seems to be a determinant of the reduced risk around or after age 50, it might not confer protection against, or it could even increase the risk of, cancers diagnosed in the years immediately following pregnancy.

Genetic Variants of Serum Uric Acid and Gout: An Analysis of > 170,000 Individuals

Background/Purpose: Gout is a common and excruciatingly painful inflammatory arthritis caused by hyperuricemia. In addition to various lifestyle risk factors, a substantial genetic predisposition to gout has long been recognized. The Global Urate Genetics Consortium (GUGC) has aimed to comprehensively investigate the genetics of serum uric acid and gout using data from _ 140,000 individuals of European-ancestry, 8,340 individuals of Indian ancestry, 5,820 African-Americans, and 15,286 Japanese. Methods: We performed discovery GWAS meta-analyses of serum urate levels (n_110,347 individuals) followed by replication analyses (n_32,813 different individuals). Our gout analysis involved 3,151 cases and 68,350 controls, including 1,036 incident gout cases that met the American College of Rheumatology Criteria. We also examined the association of gout with fractional excretion of uric acid (n_6,799). A weighted genetic urate score was constructed based on the number of risk alleles across urate-associated loci, and their association with the risk of gout was evaluated. Furthermore, we examined implicated transcript expression in cis (expression quantitative trait loci databases) for potential insights into the gene underlying the association signal. Finally, in order to further identify urate-associated genomic regions, we performed functional network analyses that incorporated prior knowledge on molecular interactions in which the gene products of implicated genes operate. Results: We identified and replicated 28 genome-wide significant loci in association with serum urate (P 5_10_8), including all previously-reported loci as well as 18 novel genetic loci. Unlike the majority of previouslyidentified loci, none of the novel loci appeared to be obvious candidates for urate transport. Rather, they were mapped to genes that encode for purine production, transcription, or growth factors with broad downstream responses. Besides SLC2A9 and ABCG2, no additional regions contained SNPs that differed significantly (P _ 5_10_8) between sexes. Urateincreasing alleles were associated with an increased risk of gout for all loci. The urate genetic risk score (ranging from 10 to 45) was significantly associated with an increased odds of prevalent gout (OR per unit increase, 1.11; 95% CI, 1.09-1.14) and incident gout (OR, 1.10; 95% CI, 1.08-1.13). Associations for many of the loci were of similar magnitude in individuals of non-European ancestry. Detailed characterization of the loci revealed associations with transcript expression and the fractional excretion of urate. Network analyses implicated the inhibins-activins signaling pathways and glucose metabolism in systemic urate control. Conclusion: The novel genetic candidates identified in this urate/gout consortium study, the largest to date, highlight the importance of metabolic control of urate production and urate excretion. The modulation by signaling processes that influence metabolic pathways such as glycolysis and the pentose phosphate pathway appear to be central mechanisms underpinned by the novel GWAS candidates. These findings may have implications for further research into urate-lowering drugs to treat and prevent gout.

The decline in breast cancer mortality in Europe: an update (to 2009).

We updated trends in breast cancer mortality in Europe up to the late 2000's. In the EU, age-adjusted (world standard population) breast cancer mortality rates declined by 6.9% between 2002 and 2006, from 17.9 to 16.7/100,000. The largest falls were in northern European countries, but more recent declines were also observed in central and eastern Europe. In 2007, all major European countries had overall breast cancer rates between 15 and 19/100,000. In relative terms, the declines in mortality were larger at younger age (-11.6% at age 20-49 years between 2002 and 2007 in the EU), and became smaller with advancing age (-6.6% at age 50-69, -5.0% at age 70-79 years). The present report confirms and further quantifies the persisting steady fall in breast cancer mortality in Europe over the last 25-30 years, which is mainly due to advancements in the therapy.

Transnational authority in the knowledge-based economy: Who sets the standards of ICT training and certification?

This article examines the extent and limits of nonstate forms of authority in international relations. It analyzes how the information and communication technology (ICT) infrastructure for the tradability of services in a global knowledge-based economy relies on informal regulatory practices for the adjustment of ICT-related skills. By focusing on the challenge that highly volatile and short-lived cycles of demands for this type of knowledge pose for ensuring the right qualification of the labor force, the article explores how companies and associations provide training and certification programs as part of a growing market for educational services setting their own standards. The existing literature on non-conventional forms of authority in the global political economy has emphasized that the consent of actors, subject to informal rules and some form of state support, remains crucial for the effectiveness of those new forms of power. However, analyses based on a limited sample of actors tend toward a narrow understanding of the issues concerned and fail to fully explore the differentiated space in which non state authority is emerging. This article develops a three-dimensional analytical framework that brings together the scope of the issues involved, the range of nonstate actors concerned, and the spatial scope of their authority. The empirical findings highlight the limits of these new forms of nonstate authority and shed light on the role of the state and international governmental organizations in this new context.

En voyage pour Monseigneur. Ambassadeurs, officiers et messagers à la cour de Savoie (XIVè-XVè siècles)

Du commandement de mon très redouté seigneur pour aller en ambassade. C'est en ces termes que les émissaires du duc de Savoie Amédée VIII (1391-1440) s'adressaient à leur prince lorsqu'ils étaient envoyés en mission : la charge d'ambassadeur résident n'existant pas encore, chaque négociation impliquait en effet un voyage.Des simples messagers jusqu'aux ambassadeurs, cet ouvrage propose pour la première fois une histoire de ces hommes qui servaient leur maître en parcourant l'Europe, dans un rayon d'action s'étendant du Portugal à l'Ecosse et de la Hongrie à l'Egypte. Il offre une vision globale de leurs missions, en évoquant tant la préparation du voyage que les moyens de transport employés, les itinéraires suivis, les périls affrontés, les problèmes de logement et d'argent, voire même les curiosités « touristiques ».Négligés par les historiens - qui se sont focalisés sur la figure d'Amédée VIII et ses capacités de fi n diplomate, notamment à l'occasion de sa médiation auprès des divers protagonistes de la guerre de Cent Ans - ces officiers voyageurs constituent un rouage fondamental de la politique internationale savoyarde.Basé principalement sur l'exceptionnelle série de comptes déposée aux Archives d'Etat de Turin, ce livre démontre également comment Amédée VIII a organisé les voyages de ses officiers au niveau législatif, administratif, financier et pratique, afin d'en faire un instrument de pouvoir et de gouvernement aussi maîtrisé que performant.Dépassant le cadre savoyard, cette étude replace le principat d'Amédée VIII et celui de son fils Louis (1440-1465) dans un contexte européen, en comparant leurs pratiques avec celles en vigueur dans les cours française, bourguignonne, anglaise et milanaise.

Family history of cancer and the risk of laryngeal cancer: a case-control study from Italy and Switzerland.

Only limited data is available on the relationship between family history of laryngeal and other neoplasms and laryngeal cancer risk. We investigated the issue using data from a multicentre case-control study conducted in Italy and Switzerland between 1992 and 2009 including 852 cases with histologically confirmed laryngeal cancer and 1970 controls admitted to hospital for acute, non neoplastic conditions. Unconditional logistic regression models adjusted for age, sex, study center, education, tobacco smoking, alcohol drinking and number of siblings were used to estimate the odds ratios (ORs) of laryngeal cancer. The multivariate OR was 2.8 (95% confidence interval [CI], 1.5-5.3) in subjects reporting a first-degree relative with laryngeal cancer, as compared to subjects with no family history. The OR was higher when the relative was diagnosed before 60 years of age (OR = 3.5, 95% CI 1.4-8.8). As compared to subjects without family history, non-smokers, and moderate drinkers, the OR was 37.1 (95% CI 9.9-139.4) for current smokers, heavy drinkers, with family history of laryngeal cancer. Family history of colorectal (OR = 1.5, 95% CI 1.0-2.3) and kidney (OR = 3.8, 95% CI 1.2-12.1) cancer were also associated to an increased risk of laryngeal cancer, while no significant increase in risk was found for family history of cancer at all sites, excluding the larynx (OR = 1.1).

Metabolic syndrome is associated with colorectal cancer in men.

AIM OF THE STUDY: We assessed the relation between metabolic syndrome (MetS) and its components and colorectal cancer. METHODS: We analysed data from a multicentre case-control study conducted in Italy and Switzerland, including 1378 cases of colon cancer, 878 cases of rectal cancer and 4661 controls. All cases were incident and histologically confirmed. Controls were subjects admitted to the same hospitals as cases with acute non-malignant conditions. MetS was defined according to the International Diabetes Federation criteria. Odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) were estimated by multiple logistic regression models, including terms for major identified confounding factors for colorectal cancer. RESULTS: With reference to each component of the MetS, the ORs of colorectal cancer in men were 1.27 (95% CI, 0.95-1.69) for diabetes, 1.24 (95% CI, 1.03-1.48) for hypertension, 1.14 (95% CI, 0.93-1.40) for hypercholesterolaemia and 1.26 (95% CI, 1.08-1.48) for overweight at age 30. The corresponding ORs in women were 1.20 (95% CI, 0.82-1.75), 0.87 (95% CI, 0.71-1.06), 0.83 (95% CI, 0.66-1.03) and 1.06 (95% CI, 0.86-1.30). Colorectal cancer risk was increased in men (OR=1.86; 95% CI, 1.21-2.86), but not in women (OR=1.13; 95% CI, 0.66-1.93), with MetS. The ORs were 2.09 (95% CI, 1.38-3.18) in men and 1.15 (95% CI, 0.68-1.94) in women with > or =3 components of the MetS, as compared to no component. Results were similar for colon and rectal cancers. CONCLUSION: This study supports a direct association between MetS and both colon and rectal cancers in men, but not in women.

Citrus fruit and cancer risk in a network of case-control studies.

BACKGROUND: Citrus fruit has shown a favorable effect against various cancers. To better understand their role in cancer risk, we analyzed data from a series of case-control studies conducted in Italy and Switzerland. PATIENTS AND METHODS: The studies included 955 patients with oral and pharyngeal cancer, 395 with esophageal, 999 with stomach, 3,634 with large bowel, 527 with laryngeal, 2,900 with breast, 454 with endometrial, 1,031 with ovarian, 1,294 with prostate, and 767 with renal cell cancer. All cancers were incident and histologically confirmed. Controls were admitted to the same network of hospitals for acute, nonneoplastic conditions. Odds ratios (OR) were estimated by multiple logistic regression models, including terms for major identified confounding factors for each cancer site, and energy intake. RESULTS: The ORs for the highest versus lowest category of citrus fruit consumption were 0.47 (95% confidence interval, CI, 0.36-0.61) for oral and pharyngeal, 0.42 (95% CI, 0.25-0.70) for esophageal, 0.69 (95% CI, 0.52-0.92) for stomach, 0.82 (95% CI, 0.72-0.93) for colorectal, and 0.55 (95% CI, 0.37-0.83) for laryngeal cancer. No consistent association was found with breast, endometrial, ovarian, prostate, and renal cell cancer. CONCLUSIONS: Our findings indicate that citrus fruit has a protective role against cancers of the digestive and upper respiratory tract.

Objectifs: Evaluer la faisabilité, les résultats préliminaires à court et long terme du vissage percutané de vissage trans -isthmique sous anesthésie locale et contrôle scannerdes lyses isthmiques de bas grades.Matériels et méthodes: Etude prospective monocentrique réalisée sur 10 patients ayant une lyse isthmique grade 1 et 2 résistant au traitement médical conventionnel. Une évaluationclinique était réalisée à un mois, 3 mois, 6 mois et un an post-opératoire par un évaluateur indépendant. L'indication est posée en concertation avec le service dechirurgie orthopédique.Résultats: Les lyses isthmiques étaient situées en L5-S1 avec 6 grades 1 et 4 grades 2. L'échelle analogique de la douleur (VAS) variait de 6 a 9 avec une moyenne de 7,8.L'indication opératoire chirurgicale était posée pour tous les patients par arthrodèse postérieure lombo -sacree. Pour chaque patient 2 vis étaient positionnées soitun total de 20 vis. Un suivi clinique était réalisé de 28 a 36 mois. L'EVA et ODI diminuaient de 7,8 +/- 1,7 à 1,9 +/- 1,2 et de 62,3 +/- 17,2 à 15,1 +/- 6,0respectivement. L'ensemble des résultats était stable dans le temps en particulier à long terme.Conclusion: La fixation précise de la lyse isthmique améliore la symptomatologie et probablement évite un glissement vertébral plus important , un suivi à plus long terme surune serie de patients plus importante devrait confirmer cette hypothèse.

In vivo study of an injectable poly(acrylonitrile)-based hydrogel paste as a bulking agent for the treatment of urinary incontinence.

Urinary incontinence can be treated by endoscopic injection of bulking agents, however, no optimal therapeutic effect has been achieved upon this treatment yet. In the present study, the development of a injectable poly(acrylonitrile) hydrogel paste is described, and its efficacy and histological behavior, once injected into the submucosal space of the minipig bladder, are evaluated. A device was developed to mix poly(acrylonitrile) hydrogel powder with glycerin, used as carrier, prior to injection into the submucosal space of the bladder. Several paste deposits, depending on the size of the bladder, were injected per animal. The implants were harvested at days 7, 14, 21, 28, 84 and 168 and analyzed morphologically and by histology. The persistence of the implants was demonstrated. However, at later time points the implants were split up and surrounded by granulomatous tissue, which was gradually replaced by histiocytes and adipocytes. Transitory focal urothelial metaplasia was observed only at day 7 and moderate foreign body reaction was detected predominantly between the second and fifth week. This study demonstrated the feasibility to develop an injectable paste of poly(acrylonitrile) hydrogel thought to provide the expected bulking effect, necessary for the treatment of urinary incontinence.
