Acquisitions thérapeutiques en médecine ambulatoire en 2013 [2013 literature findings in internal general medicine].

The prescribing of antibiotics for uncomplicated skin abscesses and diverticulitis has no benefit. Some antibiotics are more at risk of causing a Clostridium difficile infection. The tests used to exclude a history of a penicillin allergy are safe. A threshold of D-dimer adjusted for the age significantly improves the specificity of the test without affecting the sensitivity. The prescription of paraclinics tests is not an effective "treatment" for the patient's anxiety. In the sleep apnea syndrome, treatment with CPAP (Continuous positive airway pressure) appears to have more benefits compared to the mandibular advancement prosthesis. The work of primary care physicians can be supported by the work of advanced practice nurses. The limitation placed on the working hours of doctors in hospitals seems to affect their ability to spend time with their patients.

Ultrastructural changes of the internal limiting membrane removed during indocyanine green assisted peeling versus conventional surgery for an idiopathic epimacular membrane

Purpose:To evaluate the histological features of cellular retinal fragments on the internal limiting membrane (ILM) removed during epiretinal membrane peeling surgery with and without the aid of ICG diluted in 5% glucose Methods:ILM specimens removed from 88 eyes undergoing vitrectomy and membrane peeling surgery for idiopathic epiretinal membrane between 1995 and 2003 were reviewed retrospectively. Surgery was performed in all cases by the same surgeon using the same technique. ICG was diluted with 5% glucose. Histological analysis focused on the presence and characteristics of retinal structures on the retinal surface of the ILM. Statistical analysis compared the results between group I (conventional surgery without ICG) and group II (ICG-assisted peeling) Results:Seventy-one eyes underwent EMM surgery without the aid of ICG (group I) and seventeen underwent EMM ICG-assisted surgery assisted using ICG (group II). The amount of Muller cell debris on the retinal surface of the ILM was more significant in the group I (no ICG) than in the group II (ICG) (40.8 versus 11.8; p = 0.024). Large fragments of Muller cells were more frequently observed in the group I (no ICG) than in the group II (ICG) (63.4% versus 23.5%; p= 0.003).The presence of larger retinal elements such as neural axons and vessels were observed attached to retinal face of the ILM in 5 (7%) cases of the no-ICG group. No such retinal elements were detected in any of the histological ILM specimens of the ICG-assisted group Conclusions:The use of ICG diluted with 5% glucose in the aid of ILM removal during epiretinal membrane surgery was associated with less retinal debris attached to retinal face of the ILM compared to surgery in which ICG was not used. Our findings contradict previous reports in the literature, in which use of ICG diluted with balanced salt solution (BSS) was associated with more retinal fragments attached to the retinal face of the ILM. According to our results, we hypothesize that diluting ICG with 5% glucose may decrease the adhesion of the ILM to the underlying retinal layers such that less retinal debris is removed with peeling of the ILM.

Asphalt Stabilization (Asphadur)/Reduction of Reflection Cracks (Monsanto Bidim Synthetic Fabric), HR-511, 1979

ASPHALT STABILIZATION (ASPHADUR): Asphadur (now called 3M Additive 5990) was incorporated into asphaltic concrete on a lane delineation, AC resurfacing, project in Council Bluffs. The experimental feature was included in the eastbound lanes of Interstate 480, beginning at the bridge over the Missouri River and ending at the bridge over North 41st Street. The project was constructed in October 1979. The objective of the project was to investigate the manufacturer's claims of improved strength, stability and durability of an asphalt mix. REDUCTION OF REFLECTION CRACKS (MONSANTO BIDIM SYNTHETIC FABRIC): A lane delineation project was constructed in the eastbound lanes of Interstate 480 in Council Bluffs. A synthetic fabric, Monsanto Bidim C-28, was placed between the portland cement concrete and two inches of Type A asphaltic concrete resurfacing containing Asphadur. The experimental feature began at the bridge over the Missouri River and ended at the bridge over North 41st Street. The project was constructed in October 1979. The objective of this experimental project was to determine the effectiveness of the fabric in reducing reflective cracking in an asphaltic concrete overlay.

Phosphorus acquisition and internal utilization efficiency in tropical maize genotypes

The objective of this work was to determine the relative importance of phosphorus acquisition efficiency (PAE - plant P uptake per soil available P), and phosphorus internal utilization efficiency (PUTIL - grain yield per P uptake) in the P use efficiency (PUE - grain yield per soil available P), on 28 tropical maize genotypes evaluated at three low P and two high P environments. PAE was almost two times more important than PUTIL to explain the variability observed in PUE, at low P environments, and three times more important at high P environments. These results indicate that maize breeding programs, to increase PUE in these environments, should use selection index with higher weights for PAE than for PUTIL. The correlation between these two traits showed no significance at low or at high P environments, which indicates that selection in one of these traits would not affect the other. The main component of PUTIL was P quotient of utilization (grain yield per grain P) and not the P harvest index (grain P per P uptake). Selection to reduce grain P concentration should increase the quotient of utilization and consequently increase PUTIL.

Fetal testosterone (2D:4D) as predictor of cognitive reflection

The Cognitive Reflection Test (CRT) is a test introduced by S. Frederick (2005) Cognitive reflection and decision making, J Econ Perspect 19(4): 25-42. The task is designed to measure the tendency to override an intuitive response that is incorrect and to engage in further reflection that leads to the correct response. The consistent sex differences in CRT performance may suggest a role for gonadal hormones, particularly testosterone. A now widely studied putative marker for fetal testosterone is the second-to-fourth digit ratio (2D:4D). This paper tests to what extent 2D:4D, as a proxy for prenatal exposure to testosterone, can predict CRT scores in a sample of 623 students. After controlling for sex, we observe that a lower 2D:4D (reflecting a higher exposure to testosterone) is significantly associated with a higher number of correct answers. The result holds for both hands? 2D:4Ds. In addition, the effect appears to be sharper for females than for males. We also control for patience and math proficiency, which are significantly related to performance in the CRT. But the effect of 2D:4D on performance in CRT is not reduced with these controls, implying that these variables are not mediating the relationship between digit ratio and CRT.

European Integration Without EU Membership : Models, Experiences, Perspectives

At the beginning of the 1990s, the concept of "European integration" could still be said to be fairly unambiguous. Nowadays, it has become plural and complex almost to the point of unintelligibility. This is due, of course, to the internal differentiation of EU membership, with several Member States pulling out of key integrative projects such as establishing an area without frontiers, the "Schengen" area, and a common currency. But this is also due to the differentiated extension of key integrative projects to European non-EU countries - Schengen is again a case in point. Such processes of "integration without membership", the focus of the present publication, are acquiring an ever-growing topicality both in the political arena and in academia. International relations between the EU and its neighbouring countries are crucial for both, and their development through new agreements features prominently on the continent's political agenda. Over and above this aspect, the dissemination of EU values and standards beyond the Union's borders raises a whole host of theoretical and methodological questions, unsettling in some cases traditional conceptions of the autonomy and separation of national legal orders. This publication brings together the papers presented at the Integration without EU Membership workshop held in May 2008 at the EUI (Max Weber Programme and Department of Law). It aims to compare different models and experiences of integration between the EU, on the one hand, and those European countries that do not currently have an accession perspective on the other hand. In delimiting the geographical scope of the inquiry, so as to scale it down to manageable proportions, the guiding principles have been to include both the "Eastern" and "Western" neighbours of the EU, and to examine both structured frameworks of cooperation, such as the European Neighbourhood Policy and the European Economic Area, and bilateral relations developing on a more ad hoc basis. These principles are reflected in the arrangement of the papers, which consider in turn the positions of Ukraine, Russia, Norway, and Switzerland in European integration - current standing, perspectives for evolution, consequences in terms of the EU-ization of their respective legal orders1. These subjects are examined from several perspectives. We had the privilege of receiving contributions from leading practitioners and scholars from the countries concerned, from EU highranking officials, from prominent specialists in EU external relations law, and from young and talented researchers. We wish to thank them all here for their invaluable insights. We are moreover deeply indebted to Marise Cremona (EUI, Law Department, EUI) for her inspiring advice and encouragement, as well as to Ramon Marimon, Karin Tilmans, Lotte Holm, Alyson Price and Susan Garvin (Max Weber Programme, EUI) for their unflinching support throughout this project. A word is perhaps needed on the propriety and usefulness of the research concept embodied in this publication. Does it make sense to compare the integration models and experiences of countries as different as Norway, Russia, Switzerland, and Ukraine? Needless to say, this list of four evokes a staggering diversity of political, social, cultural, and economic conditions, and at least as great a diversity of approaches to European integration. Still, we would argue that such diversity only makes comparisons more meaningful. Indeed, while the particularities and idiosyncratic elements of each "model" of integration are fully displayed in the present volume, common themes and preoccupations run through the pages of every contribution: the difficulty in conceptualizing the finalité and essence of integration, which is evident in the EU today but which is greatly amplified for non-EU countries; the asymmetries and tradeoffs between integration and autonomy that are inherent in any attempt to participate in European integration from outside; the alteration of deeply seated legal concepts, and concepts about the law, that are already observable in the most integrated of the non-EU countries concerned. These issues are not transient or coincidental: they are inextricably bound up with the integration of non-EU countries in the EU project. By publishing this collection, we make no claim to have dealt with them in an exhaustive, still less in a definitive manner. Our ambition is more modest: to highlight the relevance of these themes, to place them more firmly on the scientific agenda, and to provide a stimulating basis for future research and reflection.

Médecine interne et gériatrie en soins aigus: mariage de raison [General internal medicine and geriatrics in the acute care setting: opportunities for collaboration]

The health care system faces a difficult challenge as a result of the demographic evolution. The acute hospital is especially challenged by the steady increase of the elderly population. The collaboration between internal medicine and geriatrics in this setting could prove useful to facilitate the adaptation of the acute care setting and greatly enhance education of the health care professionals. Internists and geriatricians can benefit from each other skills and competencies to develop together new models of acute care that would better match the elderly population needs.

Acquisitions thérapeutiques en médecine ambulatoire en 2012 [2012 literature findings in ambulatory internal medicine].

In 2012 several articles reported interesting findings for the ambulatory practice in internal general medicine. A negative rapid test for influenza does not rule out that diagnosis. A test assessing the walking speed in the elderly can help determining who would benefit from antihypertensive therapy. Antibiotic treatment has no benefit for acute uncomplicated rhinosinusitis and diverticulitis. Probiotics can reduce the risk of post-antibiotic diarrhea. Daily coffee intake could reduce mortality. Oral supplementation of calcium can be harmful to the cardiovascular system. Subclinical hyperthyroidism should be treated to prevent cardiovascular complications. Aspirin can prevent recurrences in case of a primary thromboembolic event. Local injection of corticosteroids under ultrasonographic guidance for plantar fasciitis can be a safe treatment. Ibuprofen can prevent acute mountain sickness.

Rhythmic growth explained by coincidence between internal and external cues.

Most organisms use circadian oscillators to coordinate physiological and developmental processes such as growth with predictable daily environmental changes like sunrise and sunset. The importance of such coordination is highlighted by studies showing that circadian dysfunction causes reduced fitness in bacteria and plants, as well as sleep and psychological disorders in humans. Plant cell growth requires energy and water-factors that oscillate owing to diurnal environmental changes. Indeed, two important factors controlling stem growth are the internal circadian oscillator and external light levels. However, most circadian studies have been performed in constant conditions, precluding mechanistic study of interactions between the clock and diurnal variation in the environment. Studies of stem elongation in diurnal conditions have revealed complex growth patterns, but no mechanism has been described. Here we show that the growth phase of Arabidopsis seedlings in diurnal light conditions is shifted 8-12 h relative to plants in continuous light, and we describe a mechanism underlying this environmental response. We find that the clock regulates transcript levels of two basic helix-loop-helix genes, phytochrome-interacting factor 4 (PIF4) and PIF5, whereas light regulates their protein abundance. These genes function as positive growth regulators; the coincidence of high transcript levels (by the clock) and protein accumulation (in the dark) allows them to promote plant growth at the end of the night. Thus, these two genes integrate clock and light signalling, and their coordinated regulation explains the observed diurnal growth rhythms. This interaction may serve as a paradigm for understanding how endogenous and environmental signals cooperate to control other processes.

P-wave velocities of samples from the Penninic of the western Alps along NFP20-west seismic-reflection profiles

Using the transit pulse method, we have determined compressional wave velocities of rocks from various geological units belonging to the Penninic zone along the NFP20-West profiles of the Swiss western Alps. The velocities have been measured at confining pressures up to 400 MPa, along three orthogonal axes defined by the macrostructure of the rocks. The samples analysed show a degree of metamorphism ranging from greenschist to eclogite facies. This collection includes schists, dolomites, gneisses and ophiolitic rocks. The mean velocities range from 5.9 km/s for a quartzitic calcschist to 7.9 km/s for an eclogitic metagabbro. The velocity anisotropy is as high as 20 %. The range of acoustic impedance is wide, from 15 to 27 10(6) kg/m2s. From these measurements, normal incident reflection coefficients for likely rock assemblages within and between geological units were estimated in order to interpret zone of the strong reflections recorded along the seismic profiles. Reflection coefficients as high as 0.17 could be determined.
