Energy-nitrogen balances and protein turnover in small and appropriate for gestational age low birthweight infants.

The aim of the present study was to compare, under the same nursing conditions, the energy-nitrogen balance and the protein turnover in small for gestational age (SGA) and appropriate for gestational age (AGA) low birthweight infants. We compared 8 SGA's (mean +/- s.d.: gestational age 35 +/- 2 weeks, birthweight 1520 +/- 330 g) to 11 AGA premature infants (32 +/- 2 weeks, birthweight 1560 +/- 240 g). When their rate of weight gain was above 15 g/kg/d (17.6 +/- 3.0 and 18.2 +/- 2.6 g/kg/d, mean postnatal age 18 +/- 10 and 20 +/- 9 d respectively) they were studied with respect to their metabolizable energy intake, their energy expenditure, their energy and protein gain and their protein turnover. Energy balance was assessed by the difference between metabolizable energy and energy expenditure as measured by indirect calorimetry. Protein gain was calculated from the amount of retained nitrogen. Protein turnover was estimated by a stable isotope enrichment technique using repeated nasogastric administration of 15N-glycine for 72 h. Although there was no difference in their metabolizable energy intakes (110 +/- 12 versus 108 +/- 11 kcal/kg/d), SGA's had a higher rate of resting energy expenditure (64 +/- 8 versus 57 +/- 8 kcal/kg/d, P less than 0.05). Protein gain and composition of weight gain was very similar in both groups (2.0 +/- 0.4 versus 2.1 +/- 0.4 g protein/kg/d; 3.5 +/- 1.1 versus 3.3 +/- 1.4 g fat/kg/d in SGA's and AGA's respectively). However, the rate of protein synthesis was significantly lower in SGA's (7.7 +/- 1.6 g/kg/d) as compared to AGA's (9.7 +/- 2.8 g/kg/d; P less than 0.05). It is concluded that SGA's have a more efficient protein gain/protein synthesis ratio since for the same weight and protein gains, SGA's show a 20 per cent slower protein turnover. They might therefore tolerate slightly higher protein intakes. Postconceptional age seems to be an important factor in the regulation of protein turnover.

The appropriate use of neurostimulation of the spinal cord and peripheral nervous system for the treatment of chronic pain and ischemic diseases: the neuromodulation appropriateness consensus committee.

INTRODUCTION: The Neuromodulation Appropriateness Consensus Committee (NACC) of the International Neuromodulation Society (INS) evaluated evidence regarding the safety and efficacy of neurostimulation to treat chronic pain, chronic critical limb ischemia, and refractory angina and recommended appropriate clinical applications. METHODS: The NACC used literature reviews, expert opinion, clinical experience, and individual research. Authors consulted the Practice Parameters for the Use of Spinal Cord Stimulation in the Treatment of Neuropathic Pain (2006), systematic reviews (1984 to 2013), and prospective and randomized controlled trials (2005 to 2013) identified through PubMed, EMBASE, and Google Scholar. RESULTS: Neurostimulation is relatively safe because of its minimally invasive and reversible characteristics. Comparison with medical management is difficult, as patients considered for neurostimulation have failed conservative management. Unlike alternative therapies, neurostimulation is not associated with medication-related side effects and has enduring effect. Device-related complications are not uncommon; however, the incidence is becoming less frequent as technology progresses and surgical skills improve. Randomized controlled studies support the efficacy of spinal cord stimulation in treating failed back surgery syndrome and complex regional pain syndrome. Similar studies of neurostimulation for peripheral neuropathic pain, postamputation pain, postherpetic neuralgia, and other causes of nerve injury are needed. International guidelines recommend spinal cord stimulation to treat refractory angina; other indications, such as congestive heart failure, are being investigated. CONCLUSIONS: Appropriate neurostimulation is safe and effective in some chronic pain conditions. Technological refinements and clinical evidence will continue to expand its use. The NACC seeks to facilitate the efficacy and safety of neurostimulation.

Appropriate therapy for fistulizing and fibrostenotic Crohn's disease: results of a multidisciplinary expert panel - EPACT II

Introduction: Many therapeutic decisions in the management of fistulizing and fibrostenotic Crohn's disease (CD) have to be taken without the benefit of strong scientific evidence. For this reason, explicit appropriateness criteria for CD fistula and stenosis treatment were developed by a multidisciplinary European expert panel in 2004 with the aim of making them easily available on the Internet and thus allowing individual case scenario evaluation; these criteria were updated in 2007. Methods: Twelve international experts convened in Geneva, Switzerland in December 2007. Explicit clinical scenarios, corresponding to real daily practice, were rated on a 9-point scale based on evidence from the published literature and panelists' own expertise. Median ratings were stratified into three categories: appropriate (7-9), uncertain (4-6) and inappropriate (1-3). Results: Overall, panelists rated 60 indications pertaining to fistulas. Antibiotics, azathioprine/6-mercaptopurine and conservative surgery are the mainstay of therapy for simple and complex fistulas. In the event of previous failure of azathioprine/6-mercaptopurine therapy, methotrexate and infliximab were considered appropriate for complex fistulas. The panel also rated 72 indications related to the management of fibrostenotic CD. The experts considered balloon dilation, if the stricture was endoscopically accessible, stricturoplasty and bowel resection to be appropriate for small bowel fibrostenotic Crohn's disease, and balloon dilation and bowel resection appropriate for fibrostenotic colonic disease. In the presence of an ileocolonic or ileorectal anastomotic stricture of <7 cm, endoscopic balloon dilation, and bowel resection were considered appropriate. Conclusion: Antibiotics, azathioprine/6-mercaptopurine, and conservative surgery are the mainstay of therapy for fistulizing Crohn's disease. Infliximab is a therapeutic option in patients without prior response to immunosuppressant therapy. In fibrostenotic Crohn's disease, endoscopic balloon dilation, if feasible, or surgical therapy should be considered. These expert recommendations are available online (www.epact.ch). Prospective evaluation is now needed to test the validity of these appropriateness criteria in clinical practice. (C) 2009 European Crohn's and Colitis Organisation. Published by Elsevier B.V.

La sécurité publique en Asie Mineure sous le Principat (Ier-IIIème s. ap. J.-C.) : institutions municipales et institutions impériales dans l'Orient romain

Présentation du plan La présente recherche se divise en cinq chapitres, plus l'introduction et la conclusion. Chaque chapitre s'ouvre par quelques mots de présentation dévoilant son contenu et expliquant son objectif, ainsi que la méthode adoptée. C'est pourquoi je ne ferai ici que d'exposer en termes généraux la façon dont s'articule le travail dans son ensemble. Les chapitres I et II sont consacrés à l'étude du contexte historique, juridique et social dans lequel s'exerce le maintien de l'ordre dans les provinces romaines d'Asie Mineure à l'époque impériale. Ils permettront de saisir quelles sont les spécificités structurelles des provinces anatoliennes dans le domaine de la sécurité publique, ainsi que d'affiner notre définition du maintien de l'ordre. Le chapitre I donnera un aperçu historique de la pénétration romaine en Anatolie depuis la période républicaine en insistant sur les changements que cela a entraînés pour cette région dans le domaine de la sécurité publique. Quant au chapitre II, il dévoilera les principaux facteurs sociaux venant ordinairement menacer l'ordre public dans les provinces anatoliennes. Ces deux premiers chapitres serviront de préambule à l'analyse proprement dite des institutions chargées de veiller à la sécurité publique en Anatolie sous le Principat, qui sera proposée dans les chapitres suivants. Les chapitres III et IV, qui sont les plus volumineux, forment le coeur de l'étude. J'y examine en parallèle les institutions municipales et les structures impériales et militaires actives dans le maintien de l'ordre présentes en Asie Mineure. Ces deux chapitres sont les plus techniques dans ce sens que chaque institution répertoriée y est décrite et examinée en détail, principalement sur la base de sources épigraphiques et juridiques. Le but est de déterminer l'origine, la diffusion, les compétences et l'utilité de chacune des structures retenues. Le chapitre V, pour sa part, est réservé à l'étude des conditions nécessaires à l'intervention directe de l'armée romaine dans les provinces anatoliennes. J'y observe aussi plusieurs cas limites où l'action des cités et celle de l'armée romaine s'entremêlent. Ce sera l'occasion de s'interroger sur l'existence d'une éventuelle répartition des tâches entre les cités et les autorités impériales en matière d'ordre public dans les provinces. Les chapitres II à V se terminent, en outre, par un bilan où les principales idées qui y ont été développées sont reprises sous la forme d'une conclusion intermédiaire. Dans la conclusion générale, j'analyse l'interaction des diverses institutions que j'aurai étudiées, dans l'intention de porter un jugement global sur la manière dont la sécurité publique est gérée dans les provinces d'Asie Mineure durant les trois premiers siècles de notre ère. Je chercherai également à savoir si la situation que j'aurai reconnue pour le cas des provinces anatoliennes est la règle pour le reste de l'empire ou si, au contraire, il s'agit d'une exception. J'en tirerai des observations générales sur le mode d'organisation et de gestion de l'empire sous le Principat, comme je me suis proposé de le faire. On trouvera à la fin du volume trois appendices historiques rassemblant de courtes digressions qui viennent s'adjoindre au corps central de l'étude; des appendices épigraphiques énumérant sous forme de listes un grand nombre des inscriptions utiles à l'élaboration de cette recherche; une bibliographie générale avec mention des abréviations employées; des illustrations et cartes; enfin, des index. Je terminerai par quelques avertissements d'ordre pratique nécessaires à la bonne consultation de ce livre. Pour ce qui est des renvois internes (lorsque je renvoie à un chapitre ou à une section de chapitre en général, et non à des pages précises), les numéros des chapitres sont exprimés en chiffres romains, tandis que les numéros des sous-chapitres sont exprimés en chiffres arabes: «Voir chap. V. 2.» signifie donc «voir section 2 du chapitre V». En ce qui concerne les inscriptions contenues dans les appendices épigraphiques, elles sont citées sous la forme d'une lettre suivie d'un numéro, par exemple «B 24»: la lettre renvoie aux listes des appendices épigraphiques (liste B dans cet exemple), le chiffre arabe au numéro de l'inscription dans la liste en question (inscription n° 24 de la liste B en l'occurrence). Quant aux notes de bas de page, la numérotation reprend au début de chaque chapitre. Sauf mention contraire, les dates s'entendent après Jésus-Christ et les traductions sont les miennes. Les abréviations utilisées pour les références aux sources primaires (sources littéraires, juridiques, épigraphiques, papyrologiques, numismatiques) et à la littérature secondaire sont développées dans la bibliographie. Enfin, je voudrais préciser que mon travail ne se veut pas une étude de géographie historique. Je ne me suis donc pas servi, en général, de cartes archéologiques, mais j'ai recouru le plus souvent, pour la localisation des villes et des régions que je mentionne, aux cartes du nouvel atlas Barrington, qui sont très commodes et tout à fait satisfaisantes pour une étude historique d'ensemble comme la mienne.

Predicting species distributions for conservation decisions.

Species distribution models (SDMs) are increasingly proposed to support conservation decision making. However, evidence of SDMs supporting solutions for on-ground conservation problems is still scarce in the scientific literature. Here, we show that successful examples exist but are still largely hidden in the grey literature, and thus less accessible for analysis and learning. Furthermore, the decision framework within which SDMs are used is rarely made explicit. Using case studies from biological invasions, identification of critical habitats, reserve selection and translocation of endangered species, we propose that SDMs may be tailored to suit a range of decision-making contexts when used within a structured and transparent decision-making process. To construct appropriate SDMs to more effectively guide conservation actions, modellers need to better understand the decision process, and decision makers need to provide feedback to modellers regarding the actual use of SDMs to support conservation decisions. This could be facilitated by individuals or institutions playing the role of 'translators' between modellers and decision makers. We encourage species distribution modellers to get involved in real decision-making processes that will benefit from their technical input; this strategy has the potential to better bridge theory and practice, and contribute to improve both scientific knowledge and conservation outcomes.

Conclusion : les usages possibles et contestables des normes et des institutions dans l'internationalisation des services

The conclusion of this volume on technical standards in the regulation of services reviews the authors' contributions to understanding the relation between tertiarisation, internationalisation and standardisation from three distinct perspectives : theoretical, institutional, and sectorial. It argues that conventional views on conditions for standardisation and internationalisation of service activities are overly restrictive, making them dependent on sectorial and institutional specificity. In emphasizing the possible and contestable uses of service standards, the volume opens a critical debate on service offshoring, underlining the social and historical constructions of its transnational logic.

Appropriate management of special situations in Crohn's disease (upper gastro-intestinal; extra-intestinal manifestations; drug safety during pregnancy and breastfeeding): results of a multidisciplinary international expert panel-EPACT II

Introduction: High-grade evidence is lacking for most therapeutic decisions in Crohn's disease. Appropriateness criteria were developed for upper gastro-intestinal, extra-intestinal manifestations and drug safety during conception, pregnancy and breastfeeding in patients with Crohn's disease, to assist the physician in clinical decision making. Methods: The European Panel on the Appropriateness of Crohn's Disease Therapy (EPACT II), a multidisciplinary international European expert panel, rated clinical scenarios based on evidence from the published literature and panelists' own clinical expertise. Median ratings (on a 9-point scale) were stratified into three categories: appropriate (7-9), uncertain (4-6 with or without disagreement) and inappropriate (1-3). Experts were also asked to rank appropriate medications by priority. Results: Proton pump inhibitors, steroids, azathioprine/6-mercaptopurine and infliximab are appropriate for upper gastro-duodenal Crohn's disease; for stenosis, endoscopic balloon dilation is the first-tine therapy, although surgery is also appropriate. Ursodeoxycholic acid is the only appropriate treatment for primary sclerosing cholangitis. Infliximab is appropriate for Pyoderma gangrenosum, ankylosing spondylitis and uveitis, steroids for Pyoderma gangrenosum and ankylosing spondylitis, adalimumab for Pyoderma gangrenosum and ankylosing spondylitis, cyclosporine-A/tacrolimus for Pyoderma gangrenosum. Mesalamine, sulfasalazine, prednisone, azathioprine/6-mercaptopurine, ciprofloxacin, and probiotics, may be administered safety during pregnancy or for patients wishing to conceive, with the exception that mate patients considering conception should avoid sulfasalazine. Metronidazol is considered safe in the 2nd and 3rd trimesters whereas infliximab is rated safe in the 1st trimester but uncertain in the 2nd and 3rd trimesters. Methotrexate is always contraindicated at conception, during pregnancy or during breastfeeding, due to its known teratogenicity. Mesalamine, prednisone, probiotics and infliximab are considered safe during breastfeeding. Conclusion: EPACT II recommendations are freely available online (www.epact.ch). The validity of these criteria should now be tested by prospective evaluation. (C) 2009 European Crohn's and Colitis Organisation. Published by Elsevier B.V. All rights reserved.

Réforme de la péréquation financière et de la répartition des tâches : incidences du transfert du domaine des institutions pour personnes handicapées aux cantons : [analyse comparative entre les cantons de Neuchâtel, Vaud, du Valais, de Bâle-Ville et de Bâle-Campagne]

La réforme de la péréquation financière et de la répartition des tâches entre la Confédération et les cantons (RPT) entrera en vigueur le 1er janvier 2008. Elle prévoit notamment le transfert de la responsabilité des institutions pour personnes handicapées de la Confédération aux cantons. Ce mémoire se concentre sur ce domaine particulier en décrivant de quelle manière les cantons se préparent pour assumer leurs nouvelles responsabilités et comment ils envisagent de redéfinir leurs relations avec les institutions spécialisées et les personnes handicapées. Par une analyse comparative menée dans les cantons de Neuchâtel, Vaud, Valais, Bâle-Ville et Bâle-Campagne des différences intercantonales importantes sont mise en évidence et permettent d'aborder la problématique générale de la mise en oeuvre d'une politique sociale dans un Etat fédéral.
