THE ROLE OF SPINDLES FOR SLEEP: MANIPULATING OSCILLATORY ACTIVITY IN THE THALAMOCORTICAL NETWORK

Modern urban lifestyle encourages the prolongation of wakefulness, leaving less and less time for sleep. Although the exact functions of sleep remain one of the biggest mysteries in neuroscience, the society is well aware of the negative consequences of sleep loss on human physical and mental health and performance. Enhancing sleep's recuperative functions might allow shortening sleep duration while preserving the beneficial effects of sleep. During sleep, brain activity oscillates across a continuum of frequencies. Individual oscillations have been suggested to underlie distinct functions for sleep and cognition. Gaining control about individual oscillations might allow boosting their specific functions. Sleep spindles are 11 - 15 Hz oscillations characteristic for light non-rapid-eye-movement sleep (NREMS) and have been proposed to play a role in memory consolidation and sleep protection against environmental stimuli. The reticular thalamic nucleus (nRt) has been identified as the major pacemaker of spindles. Intrinsic oscillatory burst discharge in nRt neurons, arising from the interplay of low-threshold (T-type) Ca2+ channels (T channels) and small conductance type 2 (SK2) K+ channels (SK2 channels), underlies this pacemaking function. In the present work we investigated the impact of altered nRt bursting on spindle generation during sleep by studying mutant mice for SK2 channels and for CaV3.3 channels, a subtype of T channels. Using in vitro electrophysiology I showed that nRt bursting was abolished in CaV3.3 knock out (CaV3.3 KO) mice. In contrast, in SK2 channel over-expressing (SK2-OE) nRt cells, intrinsic repetitive bursting was prolonged. Compared to wildtype (WT) littermates, altered nRt burst discharge lead to weakened thalamic network oscillations in vitro in CaV3.3 KO mice, while oscillatory activity was prolonged in SK2-OE mice. Sleep electroencephalographic recordings in CaV3.3 KO and SK2-OE mice revealed that reduced or potentiated nRt bursting respectively weakened or prolonged sleep spindle activity at the NREMS - REMS transition. Furthermore, SK2-OE mice showed more consolidated NREMS and increased arousal thresholds, two correlates of good sleep quality. This thesis work suggests that CaV3.3 and SK2 channels may be targeted in order to modulate sleep spindle activity. Furthermore, it proposes a novel function for spindles in NREMS consolidation. Finally, it provides evidence that sleep quality may be improved by promoting spindle activity, thereby supporting the hypothesis that sleep quality can be enhanced by modulating oscillatory activity in the brain. Le style de vie moderne favorise la prolongation de l'éveil, laissant de moins en moins de temps pour le sommeil. Même si le rôle exact du sommeil reste un des plus grands mystères des neurosciences, la société est bien consciente des conséquences négatives que provoque un manque de sommeil, à la fois sur le plan de la santé physique et mentale ainsi qu'au niveau des performances cognitives. Augmenter les fonctions récupératrices du sommeil pourrait permettre de raccourcir la durée du sommeil tout en en conservant les effets bénéfiques. Durant le sommeil, on observe des oscillations à travers un continuum de fréquences. Il a été proposé que chaque oscillation pourrait être à l'origine de fonctions spécifiques pour le sommeil et la cognition. Pouvoir de contrôler les oscillations individuelles permettrait d'augmenter leurs fonctions respectives. Les fuseaux sont des oscillations de 11 à 15 Hz caractéristiques du sommeil à ondes lentes léger et il a été suggéré qu'elles jouent un rôle majeur pour la consolidation de la mémoire ainsi que dans la protection du sommeil contre les stimuli environnementaux. Le nucleus réticulaire du thalamus (nRt) a été identifié en tant que générateur de rythme des fuseaux. Les bouffées oscillatoires intrinsèques des neurones du nRt, provenant de l'interaction de canaux calciques à bas seuil de type T (canaux T) et de canaux potassiques à faible conductance de type 2 (canaux SK2), sont à l'origine de la fonction de générateur de rythme. Dans ce travail, j'ai étudié l'impact de la modulation de bouffées de nRT sur la génération des fuseaux pendant le sommeil en investiguant des souris génétiquement modifiées pour les canaux SK2 et les canaux CaV3.3, un sous-type de canaux T. En utilisant l'électrophysiologie in vitro j'ai démontré que les bouffées du nRT étaient abolies dans les souris knock-out du type CaV3.3 (CaV3.3 KO). D'autre part, dans les cellules nRT sur-exprimant les canaux SK2 (SK2-OE), les bouffées oscillatoires intrinsèques étaient prolongées. Par rapport aux souris wild type, les souris CaV3.3 KO ont montré un affaiblissement des oscillations thalamiques en réponse à un changement des bouffées de nRT, alors que l'activité oscillatoire était prolongée dans les souris SK2-OE. Des enregistrements EEG du sommeil dans des souris de type CaV3.3 KO et SK2-OE ont révélé qu'une réduction ou augmentation des bouffées nRT ont respectivement affaibli ou prolongé l'activité des fuseaux durant les transitions du sommeil à ondes lentes au sommeil paradoxal. De plus, les souris SK2-OE ont montré des signes de consolidation du sommeil à ondes lentes et un seuil augmenté pour le réveil, deux mesures qui corrèlent avec une bonne qualité du sommeil. Le travail de cette thèse propose que les canaux CaV3.3 et SK2 pourrait être ciblés pour moduler l'activité des fuseaux. De plus, je propose une fonction nouvelle pour les fuseaux dans la consolidation du sommeil à ondes lentes. Finalement je suggère que la qualité du sommeil peut être améliorée en promouvant l'activité des fuseaux, soutenant ainsi l'idée que la qualité du sommeil peut être améliorée en modulant l'activité oscillatoire dans le cerveau.

Autologous stem cell transplantation for enteropathy-associated T-cell lymphoma: a retrospective study by the EBMT.

Enteropathy-associated T-cell lymphoma (EATL) is a rare subtype of peripheral T-cell lymphomas with a poor prognosis. Autologous stem cell transplantation (ASCT) was retrospectively evaluated as a consolidation or salvage strategy for EATL. The analysis included 44 patients who received ASCT for EATL between 2000 and 2010. Thirty-one patients (70%) were in first complete or partial remission at the time of the ASCT. With a median follow-up of 46 months, relapse incidence, progression-free survival, and overall survival were 39%, 54%, and 59% at 4 years, respectively, with only one relapse occurring beyond 18 months posttransplant. There was a trend for better survival in patients transplanted in first complete or partial remission at 4 years (66% vs 36%; P = .062). ASCT is feasible in selected patients with EATL and can yield durable disease control in a significant proportion of the patients.

Appropriateness of colonoscopy in Europe (EPAGE II): presentation of methodology, general results, and analysis of complications.

BACKGROUND AND STUDY AIMS: Appropriate use of colonoscopy is a key component of quality management in gastrointestinal endoscopy. In an update of a 1998 publication, the 2008 European Panel on the Appropriateness of Gastrointestinal Endoscopy (EPAGE II) defined appropriateness criteria for various colonoscopy indications. This introductory paper therefore deals with methodology, general appropriateness, and a review of colonoscopy complications. METHODS:The RAND/UCLA Appropriateness Method was used to evaluate the appropriateness of various diagnostic colonoscopy indications, with 14 multidisciplinary experts using a scale from 1 (extremely inappropriate) to 9 (extremely appropriate). Evidence reported in a comprehensive updated literature review was used for these decisions. Consolidation of the ratings into three appropriateness categories (appropriate, uncertain, inappropriate) was based on the median and the heterogeneity of the votes. The experts then met to discuss areas of disagreement in the light of existing evidence, followed by a second rating round, with a subsequent third voting round on necessity criteria, using much more stringent criteria (i. e. colonoscopy is deemed mandatory). RESULTS: Overall, 463 indications were rated, with 55 %, 16 % and 29 % of them being judged appropriate, uncertain and inappropriate, respectively. Perforation and hemorrhage rates, as reported in 39 studies, were in general < 0.1 % and < 0.3 %, respectively CONCLUSIONS: The updated EPAGE II criteria constitute an aid to clinical decision-making but should in no way replace individual judgment. Detailed panel results are freely available on the internet (www.epage.ch) and will thus constitute a reference source of information for clinicians.

Closed and open grade I and II tibial shaft fractures treated by reamed intramedullary nailing

RESUME Objectif : Le but de cette étude est d'évaluer les résultats du traitement par enclouage centre-médullaire alésé des fractures diaphysaires du tibia aussi bien fermées que pour les fractures ouvertes de stade I et II selon Gustillo. Méthodes: Entre 1997 et 2000, 119 patients présentant une fracture diaphysaire du tibia ont été traités dans notre service par un enclouage centre-médullaire alésé. En postopératoire, 96 patients, soit 70 fractures fermées et 26 fractures ouvertes I et II selon Gustillo, ont été suivis cliniquement et radiologiquement pour une période de plus d'une année et demi. L'introduction du clou centro-médullaire a été faite selon la technique habituelle, soit transtendineuse ou paratendineusé rotulienne. Tous les clous ont été alésés jusqu'à 1,5 mm au-dessus du diamètre du clou. Les patients ayant une fracture isolée du tibia ont été immédiatement mobilisés en charge partielle pour une période de 6 semaines. Ceux qui avaient des lésions associées, notamment au niveau de la cheville épsilatérale, ont nécessité la mise en place d'un plâtre de Type Sarmiento. Résultats : Six patients (6,3%) ont développé un syndrome des loges après chirurgie. Quarante-huit cas (50%) ont nécessité une dynamisation du clou après une période moyenne de 12 semaines en raison d'un retard de consolidation. En général, 90,6% des fractures ont consolidé après 24 semaines postopératoires en moyenne, sans aucune différence significative entre les fractures fermées et les fractures ouvertes. Deux patients (2,1 %) présentant une fracture ouverte degré II ont développé une infection profonde ayant nécessité un traitement. Nous avons également observé 9,4% de cals vicieux minimes et sans conséquence clinique. Huit patients (8,3%) ont eu une brisure des vis de .verrouillage mais également sans conséquence clinique. Au dernier contrôle, 52% des patients, dont ('introduction du clou s'est faite en transtendineux ont des douleurs antérieures du genou contre 14% parmi ceux où l'introduction était paratendineuse. Conclusion : L'enclouage centre-médullaire reste le traitement de choix pour les fractures diaphysaires du tibia, qu'elles soient fermées ou ouvertes degré I ou II selon Gustillo.

Acvbp Versus Acvbp Plus Rituximab For Young Patients With Localized Low-Risk Diffuse Large B-Cell Lymphoma: A Study By The Groupe D'etude Des Lymphomes De L'adulte

Introduction: In a prior study, we demonstrated that ACVBP + consolidation was superior to 3 cycles of CHOP + radiotherapy in young patients (pts) with localized aggressive lymphoma (Reyes F et al. N Engl J Med 2005;352:1197). This randomized trial compared in these pts ACVBP vs. ACVBP + a short course of rituximab (R-ACVBP).Methods: untreated pts between 18 and 65y with stage I/II DLBCL and no adverse prognostic factors according to the aa-IPI were eligible. ACVBP consisted of 3 induction cycles given every 2 weeks: doxorubicin (75 mg/m2) day 1, cyclophosphamide (1.2g/m2) day 1, vindesine (2 mg/m2) day 1 and 5, bleomycin (10 mg) day 1 and 5, prednisone (60 mg/m2) day 1 to 5 followed by consolidation with metothrexate, ifosfamide, VP-16 and cytarabine. R-ACVBP consisted of the same regimen combined with 4 doses of rituximab (375 mg/m2) on day 1, 15, 29 and 43. Primary objective was EFS.Results: From 01/04 to 03/08, 223 pts were randomized, 113 in ACVBP and 110 in R-ACVBP arm. Characteristics were: median age 49y (18-65), stage I 63%, extranodal involvement 45%, bulky disease 4%. CR was 94% in ACVBP and 97% in ACVBP arm (ns). With a median follow-up of 43 months, the 3-y EFS was 82% (95% CI, 73% to 88%) in ACVBP and 93% (95% CI, 87% to 97%) in R-ACVBP group (P=0.0487). The 3-y PFS was 83% (95% CI, 74% to 89%) and 95% (95% CI, 89% to 98%) respectively (P=0.0205). OS did not significantly differ with a 3-y estimates of 97% (95% CI, 90% to 99%) for ACVBP and 98% (95% CI, 92% to 100%) for R-ACVBP (P=0.686). In multivariate analysis, a longer PFS was associated with R-ACVBP arm (P=0.0302) and lower b2-m level (P=0.0164). The same proportion of pts (27%) experienced at least 1 SAE in both groups. There were 4 deaths in each arm, with 1 treatment-related death in R-ACVBP (pneumocystis jiroveci pneumonia).Conclusion: the addition of only 4 doses of rituximab to ACVBP significantly improves EFS and PFS in younger pts with low-risk localized DLBCL.

Minorités linguistiques, où êtes-vous ? : pistes et mesures pour une meilleure représentation des minorités linguistiques au sein des organisations (para-)étatiques

L'objectif de la présente étude est d'identifier et d'analyser un certain nombre de mesures et de bouquets de mesures afin de cerner quelques pistes propres à améliorer la représentation des ressortissants des minorités linguistiques francophone ou germanophone au sein d'organisations étatiques ou paraétatiques suisses actives en contexte bilingue allemand-français. Pour ce faire, nous nous sommes appuyé sur la théorie de la bureaucratie représentative et ses promesses et avons recouru à une approche d'acteurs à deux niveaux, comprenant l'envoi d'un questionnaire et l'organisation d'entretiens d'approfondissement. Dix organisations ont ainsi été approchées : Confédération, cantons, communes, anciennes régies fédérales. Il a été possible d'identifier certains enjeux et de cerner un certain nombre de mesures performantes, souvent peu onéreuses en termes de finances et d'organisation ou relevant du bon sens, intervenant à différents moments du cycle de vie d'un emploi et susceptibles d'attirer ou de fidéliser des représentants de la minorité linguistique locale au sein d'une organisation. Il a également été possible de savoir pour quelles raisons certaines mesures sont régulièrement délaissées par les organisations approchées. D'autres ont pu être identifiées au fil d'entretiens, dont certaines sont en projet mais sont susceptibles de se heurter à des obstacles d'ordres divers. D'autres, enfin, sont appelées à se développer. Elles ne sauraient toutefois se passer de soutien politique et juridique, ni d'une certaine créativité, ni d'efforts constants. Ceux-ci déboucheront toutefois sur une organisation plus riche culturellement, s'avérant par ailleurs plus démocratique du fait qu'elle reflétera mieux les citoyens qu'elle administre. Cela, sans oublier une certaine philosophie de souplesse et de tolérance réciproque entre représentants de la minorité et de la majorité linguistique.

Networks of Coordination : Swiss Business Associations as an Intermediary between Business, Politics and Administration during the 20th Century

Until the 1990's, Switzerland could be classified as either a corporatist, cooperative or coordinated market economy where non-market mechanisms of coordination among economic and political actors were very important. In this respect, Business Interest Associations (BIAs) played a key role. The aim of this paper is to look at the historical evolution of the five main peak Swiss BIAs through network analysis for five assorted dates during the 20th century (1910, 1937, 1957, 1980 and 2000) while relying on a database that includes more than 12,000 people. First, we examine the logic of membership in these associations, which allows us to analyze their position and function within the network of the Swiss economic elite. Until the 1980's, BIAs took part in the emergence and consolidation of a closely meshed national network, which declined during the two last decades of the 20th century. Second, we investigate the logic of influence of these associations by looking at the links they maintained with the political and administrative worlds through their links to the political parties and Parliament, and to the administration via the extra-parliamentary commissions (corporatist bodies). In both cases, the recent dynamic of globalization called into question the traditional role of BIAs.

Little Dairy on the Prairie: from butter makin' to high-tech agriculture, 2005

In 2001, extensive archaeological excavations were conducted at the Oneida Cheese Factory in Jones County. The county is a microcosm of larger dairying trends found throughout northeast Iowa, the state’s premier dairy-producing region. Jones County moved from homemade cheese and butter production by farm women, to the industrialization of the dairy farm and opening of cheese factories and butter creameries. A number of innovations affected the industry around the turn-of-the-twentieth century, including reliable butterfat testing, the introduction of ensilage (silos) that created yearround milk production, and consolidation of the many local creameries into larger creamery organizations, such as the Diamond Creamery run by Henry D. Sherman of Jones County. Iowa’s dairy industry of today looks very different from its heritage: consolidation and competition have drastically reduced the number of cows, dairy farms, and processing plants. In recent years, northeast Iowa has become the center of a movement to revitalize Iowa’s dairy industry, particularly through the use of value-added strategies, such as niche markets and large regional co-operatives: the lessons from Iowa’s dairying legacy are resurfacing as a solution to modern agricultural challenges.

Greenstick fractures of the middle third of the forearm. A prospective multi-centre study.

BACKGROUND: Greenstick fractures suffered during growth have a high risk for refracture and posttraumatic deformity, particularly at the forearm diaphysis. The use of a preemptive completion of the fracture by manipulation of the concave cortex is controversial and data supporting this approach are few. AIM: Aim of this study was to determine the factors which predispose to refracture and deformities, and to define therapeutic strategies. METHODS: We prospectively gathered clinical and radiographic data over a period of one year on greenstick fractures of the middle third of the forearm in children as part of a multi-centre study. Endpoint was a follow-up visit at one year. Radiographic deformity, state of consolidation at resumption of physical activities and refracture rate were analysed statistically (ANOVA, Student's t-test and Pearson's chi-square test) with regard to patient age, gender, fracture type, therapy and time in plaster. RESULTS: We collected the data of 103 patients (63 boys, 40 girls), average age 6.6 years (1.3-14.5 years), the vast majority of whom had a combined greenstick fracture of the radius and ulna. 6.7% of the patients sustained a refracture within 49 days (29-76) after plaster removal. They were significantly older (p=0.017) with a significantly higher incidence of manual completion of the fracture with radiographic signs of partial consolidation (p=0.025). Residual deformities were significantly smaller after completion of the fracture compared to reduction without completion (p=0.019) or plaster fixation alone (p<0.005). CONCLUSIONS: Completion of a greenstick fracture does not prevent refracture. Nevertheless, it diminishes the extent of secondary deformities in cases where the primary angulation exceeds the remodelling capacity. Prevention of refracture should include a routine radiographic follow-up 4-6 weeks after injury with continuation of plaster fixation in cases of partial consolidation.

STRATEGIES TO SURPASS THE VULNERABILITY OF THE SMALL ISLAND STATES WITH FEW RESOURCES: THE CASE OF CAPE VERDE

The problem of small Island Developing States (SIDS) is quite recent, end of the 80s and 90s, still looking for a theoretical consolidation. SIDS, as small states in development, formed by one or several islands geographically dispersed, present reduced population, market, territory, natural resources, including drinkable water, and, in great number of the cases, low level of economic activity, factors that together, hinder the gathering of scale economies. To these diseconomies they come to join the more elevated costs in transports and communications which, allies to lower productivities, to a smaller quality and diversification of its productions, which difficult its integration in the world economy. In some SIDS these factors are not dissociating of the few investments in infrastructures, in the formation of human resources and in productive investments, just as it happens in most of the developing countries. In ecological terms, many of them with shortage of natural resources, but integrating important ecosystems in national and world terms, but with great fragility relatively to the pollution action, of excessive fishing, of uncontrolled development of tourism, factors that, conjugated and associated to the stove effect, condition the climate and the slope of the medium level of the sea water and therefore could put in cause the own survival of some of them. The drive to the awareness of the international community towards its problems summed up with the accomplishment by the United Nations in the Barbados’s Conference, 1994 where the right to the development was emphasized, through the going up the appropriate strategies and the Programme of Action for the Sustainable Development of the SIDS. The orientation of the regional and international cooperation in that sense, sharing technology (namely clean technology and control and administration environmental technology), information and creation of capacity-building, supplying means, including financial resources, creating non discriminatory and just trade rules, it would drive to the establishment of a world system economically more equal, in which the production, the consumption, the pollution levels, the demographic politics were guided towards the sustainability. It constituted an important step for the recognition for the international community on the specificities of those states and it allowed the definition of a group of norms and politics to implement at the national, regional and international level and it was important that they continued in the sense of the sustainable development. But this Conference had in its origin previous summits: the Summit of Rio de Janeiro about Environment and Development, accomplished in 1992, which left an important document - the Agenda 21, in the Conference of Stockholm at 1972 and even in the Conference of Ramsar, 1971 about “Wetlands.” CENTRO DE ESTUDOS AFRICANOS Occasional Papers © CEA - Centro de Estudos Africanos 4 Later, the Valletta Declaration, Malta, 1998, the Forum of Small States, 2002, get the international community's attention for the problems of SIDS again, in the sense that they act to increase its resilience. If the definition of “vulnerability” was the inability of the countries to resist economical, ecological and socially to the external shocks and “resilience” as the potential for them to absorb and minimize the impact of those shocks, presenting a structure that allows them to be little affected by them, a part of the available studies, dated of the 90s, indicate that the SIDS are more vulnerable than the other developing countries. The vulnerability of SIDS results from the fact the they present an assemblage of characteristics that turns them less capable of resisting or they advance strategies that allow a larger resilience to the external shocks, either anthropogenic (economical, financial, environmental) or even natural, connected with the vicissitudes of the nature. If these vulnerability factors were grouped with the expansion of the economic capitalist system at world level, the economic and financial globalisation, the incessant search of growing profits on the part of the multinational enterprises, the technological accelerated evolution drives to a situation of disfavour of the more poor. The creation of the resilience to the external shocks, to the process of globalisation, demands from SIDS and of many other developing countries the endogen definition of strategies and solid but flexible programs of integrated development. These must be assumed by the instituted power, but also by the other stakeholders, including companies and organizations of the civil society and for the population in general. But that demands strong investment in the formation of human resources, in infrastructures, in investigation centres; it demands the creation capacity not only to produce, but also to produce differently and do international marketing. It demands institutional capacity. Cape Verde is on its way to this stage.

Austerity and anarchy: Budget cuts and social unrest in Europe, 1919-2008

Does fiscal consolidation lead to social unrest? Using cross-country evidencefor the period 1919 to 2008, we examine the extent to which societies becomeunstable after budget cuts. The results show a clear correlation between fiscalretrenchment and instability. Expenditure cuts are particularly potent infueling protests; tax rises have only small and insignificant effects. We test ifthe relationship simply reflects economic downturns, using a recently-developedIMF dataset on exogenous expenditure shocks, and conclude that this is not thecase. While autocracies and democracies show broadly similar responses to budgetcuts, countries with more constraints on the executive are less likely to seeunrest after austerity measures. Growing media penetration does not strengthenthe effect of cut-backs on the level of unrest. We also find that austerity episodesthat result in unrest lead to quick reversals of fiscal policy.

On commercial media bias

Within the spokes model of Chen and Riordan (2007) that allowsfor non-localized competition among arbitrary numbers of media outlets, we quantify the effect of concentration of ownership on qualityand bias of media content. A main result shows that too few commercial outlets, or better, too few separate owners of commercial outlets can lead to substantial bias in equilibrium. Increasing the number of outlets (commercial and non-commercial) tends to bring down this bias; but the strongest effect occurs when the number of owners is increased. Allowing for free entry provides lower bounds on fixed costs above which substantial commercial bias occurs in equilibrium.

Annual Report, Fiscal Years 2004 - 2006

DAS was established on July 1, 2003, by consolidating the departments of General Services, Information Technology, Personnel, and the Accounting Bureau of the Department of Revenue and Finance. In introducing our new department, you outlined four goals of this consolidation: 1. Improve service to customers, 2. Save money, 3. Streamline, and 4. Enhance resource flexibility for state government managers. Launch of the new department signaled more than just the consolidation of state government infrastructure providers. It also marked the first large-scale rollout of entrepreneurial management, a business model characterized by a customer-focused approach to delivering services in a competitive marketplace. In entrepreneurial management organizations, business decisions are motivated by the desire to meet customer needs and by rewards or consequences for financial performance. We’re pleased to provide this Annual Report for your review and trust you will agree that entrepreneurial management in state government is a viable working concept and remains a valuable asset to Iowans.

Diversity and regional inequalities: Assessing the outcomes of the Spanish 'System of Health Care Services'

The consolidation of a universal health system coupled with a process of regionaldevolution characterise the institutional reforms of the National Health System(NHS) in Spain in the last two decades. However, scarce empirical evidence hasbeen reported on the effects of both changes in health inputs, outputs andoutcomes, both at the country and at the regional level. This paper examinesthe empirical evidence on regional diversity, efficiency and inequality ofthese changes in the Spanish NHS using cross-correlation, panel data andexpenditure decomposition analysis. Results suggest that besides significantheterogeneity, once we take into account region-specific needs there is evidenceof efficiency improvements whilst inequalities in inputs and outcomes, althoughmore visible , do not appear to have increased in the last decade. Therefore,the devolution process in the Spanish Health System offers an interesting casefor the experimentation of health reforms related to regional diversity butcompatible with the nature of a public NHS, with no sizeable regionalinequalitiest.
