Surveillance hospitalière de l'utilisation des cathéters veineux centraux

Il existe peu d'information sur l'utilisation des catheters veineux centraux (CVC). Nous avons realise une etude de cohorte observationnelle pour quantifier les indications des CVC durant leur utilisation et investiguer la concordance des indications retenue par les soignants. Les catheters etaient suivit par des visites dans les services, les soignants questionnes avec un controle dans le dossier. Un total de 378 CVC ont ete inseres sur 292 patients correspondant a 2704 catheter-jour. 70% ont ete insere aux Soins Intensifs (SI). La duree moyenne d'utilisation etait de 5 (2-9) jours, 4 (2-7) aux SI et 8 (3-15) dans les etages. Le nombre moyen d'indications par jour par CVC etais de 1.7 (1.9 aux SI et 1.5 en dehors ; P 7j) suivit par une nutrition parenterale (22.3%). 130 catheters-jour (4.8%) etaient inutiles avec une plus grande proportion en dehors des SI (6.6%). Dans 94% des cas, les reponses des soignants etaient concordantes quant a l'indication des CVC bien que 35 controles en dehors des SI ont revele que ni le medecin ni l'infirmier ne connaissaient l'indication de la CVC. Les CVC aux SI ont une duree d'utilisation plus courte mais un plus grand nombre d'indication par rapport au CVC dans les etages. Les mesures de preventions visant l'utilisation des CVC ont plus de chances d'etre efficaces en dehors des SI.
Mycoplasmal Conjunctivitis in a European Starling

Bilateral conjunctivitis and episcleritis were identified in an adult European starling (Sturnus vulgaris). A novel mycoplasma species, Mycoplasma sturni, was isolated in pure culture from the conjunctiva of both eyes. The clinical presentation was similar to that of conjunctivitis in house finches (Carpodacus mexicanus) caused by Mycoplasma gallisepticum. However, the histologic lesions were distinct, by the presence of ulceration and epithelial hyperplasia and lacking a lymphoplasmacytic infiltration. Mycoplasma sturni ferments glucose, does not hemadsorb or hemagglutinate chicken erythrocytes, and grows rapidly at 37 C in comparison to other Mycoplasma spp. The role of M. sturni in conjunctivitis in other passerine species is presently unknown.
Effect of spatial distribution of dissipated power on modeling of SMR BAW resonators at high power levels

The modeling of bulk acoustic wave resonators at elevated power levels has been improved by taking the spatial distribution of the dominating loss mechanisms into account. The spatial distribution of the dissipated power enables more accurate modeling of the temperature increase caused by the applied power. Thus, it is also possible to more accurately model the frequency shifts of the resonators' impedance curves resulting from the temperature increase caused by the applied power. Simulation and measurement results for the temperatures and impedances of the resonators with different layerstacks at high power loads are presented. The simulation and measurement results are in good agreement, confirming the presented modeling approach. Furthermore, the de-embedding procedure used to obtain vectorial scattering parameters of the resonators during high power loads, the according measurement setup, and the procedure for measuring absolute temperatures by infrared thermography are discussed.
Knowledge transfer in a probabilistic Language Of Thought

In many domains, people are able to transfer abstract knowledge about objects, events, or contexts that are superficially dissimilar, enabling striking new insights and inferences. We provide evidence that this ability is naturally explained as the addition of new primitive elements to a compositional mental representation, such as that in the probabilistic Language Of Thought (LOT). We conducted a transfer-learning experiment in which participants learned about two sequences, one after the other. We show that participants’ ability to learn the second sequence is affected the first sequence they saw. We test two probabilistic models to evaluate alternative theories of how algorithmic knowledge is transferred from the first to second sequence: one model rationally updates the prior probability of the primitive operations in the LOT based on what was used in the first sequence; the other stores previously likely hypotheses as new primitives. Both models perform better than baselines in explaining behavior, with the human subjects appearing to transfer entire hypotheses when they can, and otherwise updating the prior on primitives.
Clinical experience with topical calcitriol (1,25‐dihydroxy‐vitamin D3) in psoriasis

The use of vitamin D analogues for the treatment of chronic plaque psoriasis is well documented. Of importance now is their comparability and compatibility with other established treatments for psoriasis. This paper reviews five studies with calcitriol 3 μg g−1 ointment (Silkis ointment®, Galderma Laboratories). Calcitriol applied twice daily was found to be as effective as short‐contact dithranol in terms of global improvement and PASI scores. However, patients favoured calcitriol over dithranol when both quality of life and treatment acceptability were assessed. Two studies provide evidence of the benefit of combining calcitriol with other antipsoriatic therapies. Combination with ultraviolet (UV) B phototherapy proved as effective as UVB alone over an 8‐week period; however, the combination had a radiation dose‐sparing effect, thus reducing the risk of adverse events. Likewise, calcitriol combined with betamethasone valerate (each applied separately, once daily) was as efficacious as twice‐daily betamethasone, thereby achieving a corticosteroid‐sparing effect. Finally, two studies confirm that calcitriol 3 μg g−1 ointment can be used safely in patients with psoriasis of the head and confirm the high level of clinical efficacy achieved with this compound.
A Novel Algorithm for Solving the Coverage Hole and the Complete Coverage Range in Wireless Sensor Networks

Third, an algorithm is programmed to calculate the area of coverage hole and the total coverage range. At last, the numerical example shows that given a kind of node deployment, a group of area values and ratios corresponding to the different numbers of failed nodes and simulation times can be successfully obtained.
The mini-incision donor nephrectomy is best suited for Indian patients undergoing live donor nephrectomy: Against the motion

Donor nephrectomy is performed in a healthy human who otherwise does not require any surgery. Between 1954 and 1994, the open donor nephrectomy (ODN) through fl ank incision was considered as a standard procedure for kidney donation. Flank pain, incisional hernia, neuralgia, and muscle weakness were observed in large number of donors undergoing ODN. Ratner performed the fi rst laparoscopic donor nephrectomy (LDN) in 1995;[1] since then several other institutions have started performing LDN with the incentive to the donor having less pain, early ambulation, early resumption of regular activity, and rapid recovery. [26] All these studies with high levels of evidence-based results, either randomized, controlled trials or prospective, nonrandomized trials fi nd that compared to ODN, LDN provides equal graft function, rejection rate, urological complications, and patient and graft survival. These studies, however, suggest slightly increased operative time, marginally increased warm ischemia time, and increased major complications requiring reoperation (especially in the early learning phase) in the laparoscopic cases compared to the open approach. A critical analysis of delayed graft function after LDN found that female donor kidneys into male recipients and highly HLA-mismatched donors were signifi cant factors in delayed graft function, but that no variable related to the laparoscopic procedure itself (prolonged carbon dioxide pneumoperitoneum, warm ischemia time, renal artery length, use of right kidney) affected the functional outcome of the allograrft. [7] Recognizing the disincentives of the ODN and understanding the advantages of the small retrieval incisions performed during LDN, few surgeons have stared performing “miniincision” ODN. The intention of this article is to review the status of “mini-incision” ODN in comparison to LDN.
Mental load and the measurement of heart rate variability.

A number of studies concerning heart rate variability and mental load arereviewed It is concluded that in paced choice reaction tasks the number of reversal pointsin the cardiotachogram is the most sensitive measure of the load of the task.This measure was strongly correlated with respiration Spectral analysis of heart rate variability revealed the existence of a frequency component at about 0·10 Hz, a respiration frequency and sometimes a task frequency. In a number of tasks the respiration frequency increased, and the amplitude of energy in the lower frequencies decreased (i.e. there was a decrease in heart rate variability).
Performance analysis of MIMO systems with antenna selection over quasi-static fading channels

We examine the performance of multiple-input/multiple-output (MIMO) systems with antenna selection. We show that regardless of the underlying space-time code, the diversity gain is maintained whereas the coding gain deteriorates by a value upper bounded by 10 log/sub 10/ (M/L) dB when L out of M antennas are selected at the receiver.
Local Random Sparse Coding for Human Action Recognition in Wireless Sensor Networks

Recognizing human action in wireless sensor networks (WSN) has raised a great interest owing to the requirements of real-world applications. Recently, the bag-of-features model (BOF) has proved effective in human action recognition. In this paper, we propose a novel method named local random sparse coding (LRSC) for human action recognition in WSN based on the BOF model. The contribution is twofold. First, we utilize random projection (RP) technique for each feature vector to alleviate the curse of dimensionality. Second, we consider the locality of codebook and correspondingly propose to reconstruct the features using similar codewords. Our method is verified on the KTH and UCF Sports databases, and the experimental results demonstrate that our method achieves better results than that of previous methods on human action recognition in WSN.

Extraction Blood Vessels from Retinal Fundus Image Based on Fuzzy C-Median Clustering Algorithm

An automated method detection and extraction of blood vessels in retinal images would be described. The proposed algorithm is composed of three steps: matched filtering, fuzzy c-median (FCMED) clustering and label filtering. First, the matched filter technique is to enhance visualization of the blood vessels in retinal image. Secondly, the FCMED clustering is to keep the spatial structure of vascular tree segments. Finally, label filter technique is used to remove misclassified pixels. The algorithm has been tested on twenty sets in ocular fundus images, and experimental results are compared with clinically generated vessel segmentation and are evaluated in terms of sensitivity and specificity. This method performs well in analyzing anatomical structures in retinal image.
babA2- and cagA-Positive Helicobacter pylori Strains Are Associated with Duodenal Ulcer and Gastric Carcinoma in Brazil

ABSTRACT The babA2 and cagA genes were investigated in 208 Brazilian Helicobacter pylori strains. A strong association between babA2 and duodenal ulcer or gastric carcinoma was observed, even after adjusting for confounding factors, such as age, gender, and cagA status. cagA-positive strains were also independently associated with H. pylori-related diseases.
Ageing first passage time density in continuous time random walks and quenched energy landscapes

We study the first passage dynamics of an ageing stochastic process in the continuous time random walk (CTRW) framework. In such CTRW processes the test particle performs a random walk, in which successive steps are separated by random waiting times distributed in terms of the waiting time probability density function &psgr; ( t ) ≃ t − 1 − &agr; ? > ( 0 ≤ &agr; ≤ 2 ? > ). An ageing stochastic process is defined by the explicit dependence of its dynamic quantities on the ageing time ta, the time elapsed between its preparation and the start of the observation. Subdiffusive ageing CTRWs with 0 < &agr; < 1 ? > describe systems such as charge carriers in amorphous semiconducters, tracer dispersion in geological and biological systems, or the dynamics of blinking quantum dots. We derive the exact forms of the first passage time density for an ageing subdiffusive CTRW in the semi-infinite, confined, and biased case, finding different scaling regimes for weakly, intermediately, and strongly aged systems: these regimes, with different scaling laws, are also found when the scaling exponent is in the range 1 < &agr; < 2 ? > , for sufficiently long ta. We compare our results with the ageing motion of a test particle in a quenched energy landscape. We test our theoretical results in the quenched landscape against simulations: only when the bias is strong enough, the correlations from returning to previously visited sites become insignificant and the results approach the ageing CTRW results. With small bias or without bias, the ageing effects disappear and a change in the exponent compared to the case of a completely annealed landscape can be found, reflecting the build-up of correlations in the quenched landscape.
Genetic diversity of Saccharina latissima (Phaeophyceae) along a salinity gradient in the North Sea–Baltic Sea transition zone

The North Sea–Baltic Sea transition zone constitutes a boundary area for the kelp species Saccharina latissima due to a strong salinity gradient operating in the area. Furthermore, the existence of S. latissima there, along Danish waters, is fairly patchy as hard bottom is scarce. In this study, patterns of genetic diversity of S. latissima populations were evaluated along the salinity gradient area of Danish waters (here designated brackish) and were compared to reference sites (here designated marine) outside the gradient area, using microsatellite markers. The results showed that the S. latissima populations were structured into two clusters corresponding to brackish versus marine sites, and that gene flow was reduced both between clusters and between populations within clusters. In addition, results provided empirical evidence that marginal populations of S. latissima in the salinity gradient area exhibited a distinct genetic structure when compared to marine ones. Brackish populations were less diverse, more related, and showed increased differentiation over distance compared to marine populations. The isolation of the brackish S. latissima populations within the salinity gradient area of Danish waters in conjunction with their general low genetic diversity makes these populations vulnerable to ongoing environmental and climate change, predicted to result in declining salinity in the Baltic Sea area that may alter the future distribution and performance of S. latissima in the area.
Energy benchmarks: a detailed analysis

In light of an increase in energy cost and energy consciousness industry standard organizations such as Transaction Processing Performance Council (TPC), Standard Performance Evaluation Corporation (SPEC) and Storage Performance Council (SPC) as well as the U.S. Environmental Protection Agency have developed tests to measure energy consumption of computer systems. Although all of these consortia aim at standardizing power consumption measurement using benchmarks, ultimately aiming to reduce overall power consumption, and to aid in making purchase decisions, their methodologies differ slightly. For instance, some organizations developed specialized benchmarks while others added energy metrics to existing benchmarks. In this paper we give a comprehensive overview of the currently available energy benchmarks followed by an in depth analysis of their commonalities and differences.
Endoscopic Management of Early Supraglottic Cancer

An initial endoscopic surgical approach to early supraglottic cancer provides the surgeon with the ability to accurately stage these lesions, avoiding possible undertreatment while allowing for a valuable treatment option for those supraglottic cancers with histologically incontrovertibly superficial disease. Early invasion of the preepiglottic and paraglottic spaces can be determined accurately without altering or delaying any treatment option (open surgical excision, radiotherapy, or chemotherapy). The tendency of supraglottic cancers to transgress the natural foramina of the epiglottis is well established, and the concern about this depth of invasion is reflected by the 1977 revised staging criteria, which required assessment of the preepiglottic space (PES). Along with the microscope and the carbon dioxide laser, the adjustable supraglottiscope facilitates the determination of PES invasion and facilitates en bloc excision of superficial supraglottic cancers. The resulting morbidity typically is no different from that with routine direct endoscopy and biopsy.
Functional and Histological Changes in Rat Lung after Boron Neutron Capture Therapy

Abstract Kiger, J. L. , Kiger, W. S. , III, Riley, K. J., Binns, P. J., Patel, H. , Hopewell, J. W. , Harling, O. K. , Busse, P. M. and Coderre, J. A. Functional and Histological Changes in Rat Lung after Boron Neutron Capture Therapy. Radiat. Res. 170, 60–69 (2008). The motivation for this work was an unexpected occurrence of lung side effects in two human subjects undergoing cranial boron neutron capture therapy (BNCT). The objectives were to determine experimentally the biological weighting factors in rat lung for the high-LET dose components for a retrospective assessment of the dose to human lung during cranial BNCT. Lung damage after whole-thorax irradiation was assessed by serial measurement of breathing rate and evaluation of terminal lung histology. A positive response was defined as a breathing rate 20% above the control group mean and categorized as occurring either early (<110 days) or late (>110 days). The ED50 values derived from probit analyses of the early breathing rate dose–response data for X rays and neutrons were 11.4 ± 0.4 and 9.2 ± 0.6 Gy, respectively, and were similar for the other end points. The ED50 values for irradiation with neutrons plus p-boronophenylalanine were 8.7 ± 1.0 and 6.7 ± 0.4 for the early and late breathing rate responses, respectively, and 7.0 ± 0.5 Gy for the histological response. The RBEs for thermal neutrons ranged between 2.9 ± 0.7 and 3.1 ± 1.2 for all end points. The weighting factors for the boron component of the dose differed significantly between the early (1.4 ± 0.3) and late (2.3 ± 0.3) breathing rate end points. A reassessment of doses in patients during cranial BNCT confirmed that the maximum weighted doses were well below the threshold for the onset of pneumonitis in healthy human lung.
A qualitative analysis of a complementary differential LC injection-locked frequency divider based on direct injection

LC injection-locked frequency dividers (ILFDs) are attractive in frequency synthesizers because of their low power consumption compared to conventional digital dividers. The drawback of LC ILFDs is the narrow widths of their locked regions. One of the techniques to increase the locking range in these dividers is to use direct injection. In this paper, we present a simplified model of direct injection in an LC ILFD. Simulation results obtained from canonical ordinary differential equations match SPICE simulations qualitatively.
Aggressive behaviour at first contact with services: findings from the AESOP First Episode Psychosis Study

Background. Aggressive behaviour is increased among those with schizophrenia but less is known about those with affective psychoses. Similarly, little is known about aggressive behaviour occurring at the onset of illness. Method. The main reasons for presentation to services were examined among those recruited to a UK-based first episode psychosis study. The proportion of individuals presenting with aggressive behaviour was determined and these individuals were compared to those who were not aggressive on a range of variables including sociodemographic, clinical, criminal history, service contact, and symptom characteristics. Among the aggressive group, those who were physically violent were distinguished from those who were not violent but who were still perceived to present a risk of violence to others. Results. Almost 40% (n=194) of the sample were aggressive at first contact with services; approximately half of these were physically violent (n=103). Younger age, African-Caribbean ethnicity and a history of previous violent offending were independently associated with aggression. Aggressive behaviour was associated with a diagnosis of mania and individual manic symptoms were also associated with aggression both for the whole sample and for those with schizophrenia. Factors differentiating violent from non-violent aggressive patients included male gender, lower social class and past violent offending. Conclusions. Aggressive behaviour is not an uncommon feature in those presenting with first episode psychosis. Sociodemographic and past offending factors are associated with aggression and further differentiate those presenting with more serious violence. A diagnosis of mania and the presence of manic symptoms are associated with aggression.
Challenges posed by web-based retrieval of scientific papers: Okapi participation in TIPS

This paper reviews some of the past Okapi research and discusses the role of Okapi in the current TIPS project. The main purpose is to report new challenges faced by probabilistic text retrieval in the web environment and to indicate some of the solutions that are currently under investigation. In this context, extraction of indexing units from formatted document sources, user interface design, implementation of field searching and query expansion within the framework of probabilistic searching are discussed. The problem of maintaining session continuity in the web environment and a possible solution to this problem are outlined. Other challenges posed by the open nature of the web environment are also indicated. These include the difficulty of delimiting the boundaries of a search session and the potential of the web for collaborative information retrieval. A system for collaboratively filtering documents based on their contents is described in this connection. Issues surrounding the integration of Okapi with other pieces of software being developed for the TIPS project are also briefly discussed.
