One out of four very preterm infants will present with circulatory maladaptation during the first two days of life, with an increased risk of early complications and long term sequelae. Appreciation of those transitional difficulties cannot be limited to blood pressure. Assesment of blood pressure itself must be done in relation with gestational age and birth weight adapted norms. The effects of therapies for low systemic blood flow on blood pressure, organs and cerebral circulations are better understood, but none of them has assessed for mortality or neurodevelopmental outcomes.

All over the world, depression represents a major public health issue. According to WHO, it is the fifth disease in the world (in years of illness), the second for people aged 15 to 44 and by 2020, it could become the second in the whole world population after cardiovascular diseases. Although increasingly safer and more efficient antidepressants are available, physicians are frequently confronted with the problem of resistant depression. Indeed, an estimated 30 to 45% of patients treated for major depressive disorder have either a partial response or no response at all to the antidepressive treatment. Residual symptoms are very common. Besides usual strategies such as lithium or thyroid hormones adding, some new approaches are now being used to improve the treatment of resistant depression. These are in particular pharmacological strategies such as switching or augmentation, psychotherapy and cerebral stimulation technology. This article reviews the latest clinical and therapeutic aspects of resistant depression. [less ▲]

Background and aims: To assess the prevalence and impact of osteoarthritis (OA) and osteoporosis (OP) on health-related quality of life (HRQOL) among active subjects employed in the public workforce in Belgium. Methods: A cohort of 3440 subjects employed by the Liege City Council was prospectively followed for 6 months. The employees were asked to fill in a monthly log in a health record book, of data regarding their healthcare consumption due to OA and OP. HRQOL was assessed using the Medical Outcomes Study Short Form-36 (SF-36). Results: 1811 subjects (52.6%) filled in at least one questionnaire. The mean duration of follow-up was 3.46 months. The self-reported prevalence of OA and OP at entry to the study were respectively 34.1% and 5.3%. 3.6% of subjects reported suffering from both OA and OP. Subjects with OA and both OA and OP had significantly lower scores on all SF-36 dimensions compared with normal subjects, reflecting a worse HRQOL. The OP group had significantly lower mean scores for physical functioning and pain compared with controls. Subjects with both OA and OP had significantly lower values for physical functioning, physical role and pain when compared with the OA and OP groups. Conclusions: The results of this survey of a large sample of active subjects show that self-reported osteoarthritis and osteoporosis are common in the workplace. Both diseases have a major impact on health-related quality of life compared with that of people without self-reported musculoskeletal diseases. [less ▲]

In developing countries chronic kidney disease (CKD) is a growing problem. In most of sub-Saharan Africa, the vast majority of patients with CKD die because of lack of treatment. Renal replacement therapy is expensive, which makes it unaffordable to the residents of low-income regions. A solution to this problem may lie in preventive interventions. This editorial will focus on the reasons and some ways to reach such objectives. [less ▲]

High multiplicity scheduling problems arise naturally in contemporary production settings where manufacturers combine economies of scale with high product variety. Despite their frequent occurrence in practice, the complexity of high multiplicity problems - as opposed to classical, single multiplicity problems - is in many cases not well understood. In this paper, we discuss various concepts and results that enable a better understanding of the nature and complexity of high multiplicity scheduling problems. The paper extends the framework presented in Brauner et al. [Journal of Combinatorial Optimization (2005) Vol. 9, pp. 313-323] for single machine, non-preemptive high multiplicity scheduling problems, to more general classes of problems. [less ▲]

Evaluation of the aid of an emergency mobile unit to transfer monitorized patients to a University hospital, in the political context of regional care network offering highly qualified but restricted tertiary area centres, and an open prospective study conducted over the 5 first months in 2006. The call regulation was assessed by the emergency physician of the transfer team and all missions were concluded with an evaluating report. An amount of 197 requests were taken into account from which 80 % were addressed between 8 am and 8 pm. The mean average time interval for missions was 59 minutes (base to base) and the distance covered was 20.7 km as a mean. In essence, indications for medical secondary transfer regarded patients in need for acute coronary care (42.6%), specific intensive care (26.4%) and neurosurgical interventions (19.3%). We noted that endotracheal intubation occurred in only one case. Mortality during such a transfer activity was absent. Medical transfer unit allows the development of specific high qualified network resources owing to the secondary addressee of patients. However, the weak incidence of complication questions the practice of systematic medical accompanying during such transfers. [less ▲]

In this letter, the Schottky-barrier height (SBH) lowering in Pt silicide/n-Si junctions and its implications to Schottky-barrier source/drain p-field-effect transistors (p-SBFETs) are studied experimentally and numerically. We demonstrate that the increase of the n-Si substrate doping is responsible for a larger hole SBH lowering through an image-force mechanism, which leads to a substantial gain of the drive current in the long-channel bulk p-SBFETs. Numerical simulations. show that the channel doping concentration is also critical for short-channel p/n-silicon-on-insulator SBFET performance. [less ▲]

Le réchauffement climatique dû aux émissions massives de gaz à effet de serre devient une préoccupation centrale en matière d’environnement. Nos choix en matière d’alimentation peuvent avoir une influence sur les émissions de CO2. Nous faisons nos courses, le plus souvent au supermarché. Nous achetons des produits frais, meilleurs et plus sains. Nous perdons la notion de saison et oublions les productions locales car il est devenu normal de trouver des poires et des pommes des quatre coins du monde en été. Pour Noël, fraises d’Israël, cerises d'Argentine ou myrtilles du Chili nous sont proposées. Et toute l’année, agneau de Nouvelle-Zélande, boeuf d’Argentine, haricots du Kenya ou asperges du Pérou sont disponibles en magasin, le plus souvent venus par avion, un mode de transport très polluant, avec des émissions de CO2 60 plus importantes que le transport par voie maritime. Tous ces transports de produits alimentaires frais ont un coût environnemental important lié notamment aux émissions de gaz à effet de serre. Ainsi, un seul de nos repas peut générer plus d’émissions CO2 qu’une voiture sur 100 km. L’objectif de l’action ne consiste pas à vouloir interdire les importations de ces produits frais, mais de permettre au consommateur de faire son choix en connaissance de cause. La proposition est que les distributeurs appliquent des logos (un avion rouge et un bateau bleu) indiquant systématiquement et clairement le mode de transport utilisé pour l’acheminement intercontinental de ces marchandises, accompagné de la mention claire et lisible du lieu de production.

This paper employs dissipativity theory for the global analysis of limit cycles in particular dynamical systems of possibly high dimension. Oscillators are regarded as open systems that satisfy a particular dissipation inequality. It is shown that this characterization has implications for the global stability analysis of limit cycle oscillations: i) in isolated oscillators, ii) in interconnections of oscillators, and iii) for the global synchrony analysis in interconnections of identical oscillators.

Diffusion is an important transport process in low permeability media, which play an important role in contamination and remediation of natural environments. The calculation of equivalent diffusion parameters has however not been extensively explored. In this paper, expressions of the equivalent diffusion coefficient and the equivalent diffusion accessible porosity normal to the layering in a layered porous medium are derived based on analytical solutions of the diffusion equation. The expressions show that the equivalent diffusion coefficient changes with time. It is equal to the power average with p = -0.5 for small times and converges to the harmonic average for large times. The equivalent diffusion accessible porosity is the harmonic average of the porosities of the individual layers for all times. The expressions are verified numerically for several test cases.

Ce travail analyse la relation entre le jugement esthétique qui catégorise quelque chose comme Kitsch et l’authenticité et/ou la reproductibilité des objets, c’est-à-dire leur histoire de production. J’ai analysé les procédures de « Kitschification » et les conditions à travers lesquelles se forment et se justifient certains jugements de goût à une certaine période et dans une certaine culture. En partant de la distinction du philosophe Nelson Goodman entre « arts autographiques » et « arts allographiques » j’ai pris en considération le cas du Parthénon de Nashville, monument qui se présente comme la reconstruction du Parthénon d’Athènes, et qui apparaît comme une œuvre plus parfaite et donc plus « originale » de l’original lui-même. Cette analyse démontre que le jugement de goût ne peut pas renvoyer à la simple configuration textuelle d’un objet et donc à ses caractéristiques morphologiques, et que le jugement de goût dépend par contre de l’insertion spatio-temporelle (intertextuelle et interculturelle) de l’objet pris en considération. Dans cet article j’ai également analysé les notions d’aura (Benjamin), de patine, outre celles d’autographie et d’allographie par rapport aux arts architectural et pictural. [less ▲]

The main goal of Goldberg's new book 'Constructions at work' is the establishment of a psychologically and cross-linguistically realistic model of our knowledge of language within the framework of construction grammar (CxG; see Goldberg 1995, Croft 2001). The main claim is that our language system consists of a series of generalizations, which are CONSTRUCTED on the basis of input similarities and general cognitive mechanisms. [less ▲]
