Le temps des consommations comme oubli du présent
Authors: Le Garrec Sophie 
Published: October 2011

Résumé Les nouvelles mutations en cours depuis quelques décennies dans nos sociétés ne sont pas sans effets sur les rapports aux temporalités et plus particulièrement celles des jeunes. Incertitude et précarité face à l’avenir, positionnement liminal dans le présent, génèrent craintes et pressions pour cette partie de la population en phase de construction identitaire. En outre, les perceptions et regards stigmatisants drainés par les mondes des adultes à leur égard ne facilitent guère la quête d’une confiance assurée et la mobilisation de ressources pour « faire face ». Le présent, largement indexé sur un avenir à structurer et composer, est ressenti alors comme une pesanteur. Dans ces contextes, les effets des addictions sont ressentis comme des temps de parenthèses permettant d’occulter les pressions du quotidien et d’effacer momentanément, par l’oubli, les craintes. Au vu de ces résultats, les logiques de prévention des pratiques alcoolo-toxico-tabagiques – encore largement axées sur une vision médicalisée – questionnent dès lors l’efficience des actions et des médiations avec ce « public cible ».
In Vino Vieillissimo : au temps du « plus jamais », dernier plaisir ou ultime tabou ? À propos des vieux addictés
Authors: Griner-Abraham Véronique 
Published: October 2011

Résumé Parler d’addiction et de temporalité au grand âge semble presque indécent. Et pourtant, l’épidémiologie et la clinique sont éloquentes et rentrent en résonance avec le silence des prises en charge adaptées à cette classe d’âge. Pourquoi ce déni de la réalité, ce désinvestissement du dépistage et des soins ? L’addiction a un sens dans la psychopathologie du vieillissement. Les conduites de dépendance des sujets âgés semblent à relier aux problématiques de deuils et de pertes auxquelles on ne peut plus se soustraire. Face à l’inéluctable, la tentation des soignants est de battre le rappel de la sagesse des désirs pour n’évoquer que besoin et plaisir afin de mettre l’angoisse à distance. À l’époque où la révolution de la longévité se heurte à celle de la communication, dans des temporalités pour le moins différentes, la souffrance de ces vieux addictés semble majorée par l’absence de solutions sociétales adaptées et illustre malheureusement les inégalités croissantes des politiques de santé.
Unusual Cause of Childhood Anemia: Imerslund Grasbeck Syndrome
Authors: Laxminarayana Kishan Prasad Hosapatna , Yeshvanth Sunil Kumar , Shetty Jayaprakash K , Permi Harish S , Rao Chandrika 
Published: October 2011

ABSTRACTImerslund Grasbeck syndrome (IGS) is a rare autosomal recessive childhood disorder characterized by selective Vitamin (vit) B 12 malabsorption with asymptomatic proteinuria without any structural renal pathology. The patients stay healthy for decades with life-long parenteral vit B12. We report a case of young female who presented with pancytopenia and proteinuria, evaluated in local hospitals as chronic hemolytic anemia (autoimmune cause), finally diagnosed as IGS on complete evaluation. She was treated with injectable vit B12 (1000 μg cyanocobalalmin) and showed drastic recovery. IGS should be considered in patients with megaloblastic anemia not responding to oral vit B12 and associated proteinuria.

ABSTRACTChromophobe renal cell carcinoma is a relatively uncommon variant of renal cell carcinoma. Eosinophilic variant of chromophobe renal cell carcinoma (EVCRCC) is still less frequent and is composed predominantly of small to medium-sized cells with abundant granular eosinophilic cytoplasm. We report two cases of EVCRCC, with one having a rare association of right atrial myxoma. We present these cases, due to the rarity of EVCRCC and an unusual association of right atrial myxoma in one of them. Both patients recovered well after surgery, with no recurrence or metastasis after 2 years of follow-up.

Authors: Vyas Dhara H , Shah Parul D 
Published: October 2011

ABSTRACTVisceral leishmaniasis (VL), though widely prevalent in India, is not seen in the Rajasthan where the dry, hot and arid climatic conditions create a hostile environment for the growth of the parasite or its vector, the sandfly. We present a case of VL in a patient co-infected with HIV from this region. A 34-year-old known case of a HIV-positive patient presented to the skin department of our hospital with multiple, nontender, erythematous, papulonodular lesions all over the body for 6 months with history of weight loss and low-grade fever. Important examination findings were pallor, inguinal lymphadenopathy and hepatosplenomegaly. Laboratory findings included anemia, leucopenia, hypergammaglobulinemia and altered leucocytes to erythrocyte ratio. Buffy coat examination and bone marrow aspirates showed the presence of leishman bodies inside monocytes and macrophages respectively as well as extracellularly also. The patient was treated with amphotericin B intravenously and responded well to the treatment.

Background Increased speed and resolution of ultrasound have made it a first-line modality for the abdominal examination. During the last 5 years trans-abdominal ultrasonography has been used increasingly, for assessment of patients with small bowel (SB) diseases. Around 350 such examinations are performed annually in the diagnostic imaging department at Azhar University Hospital. Hence, the aim is to determine if the ultrafast three-dimensional ultrasound (U3D US) is potent for optimal examination of SB diseases. Patients and Methods Tap-water intake has been used to distend the SB. All patients have been examined in supine position. The U3D US data of 198 patients with SB diseases were assessed. The proximal and distal SB image quality along with the evaluation of bowel distention, motility and lesions were reported. Results Image quality was good in all examinations. Adequate demonstration of the proximal and distal SB was obtained in all of U3D US examinations. The inclusive diagnostic accuracy of U3D US was precise in 92.3%. Proximal SB was, however, less frequently involved, particularly in patients below the age of 30 years ( P = 0.050). Conclusion The diagnostic accuracy of U3D US enterography is valuable for detecting SB lesions. This modality is widely available, inexpensive and easy technique, can be used as an initial investigation in the evaluation of patients with SB disorders.

Published: October 2011

Purpose. The population of military veterans attending college is rapidly growing as veterans return from Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF). We sought to describe patterns of student veterans' health-related behaviors and how they might differ from their nonveteran peers. Design. We analyzed data from the 2008 Boynton College Student Health Survey (CSHS). Setting. CSHS participants completed an anonymous online survey. Subjects. The CSHS sampled students (n = 8651) attending public, private, 2-year, and 4-year postsecondary educational institutions in Minnesota. Measures. The CSHS included items on substance use (including alcohol and tobacco), safety, nutrition, and physical activity. Analysis. We described demographics of OEF/OIF veteran, non-OEF/OIF veteran, and nonveteran students and used Poisson regression to compute adjusted relative risks (ARBs) with 95% confidence intervals (CIs) to characterize associations between veteran status and health behaviors. Results. After controlling for demographics, veteran students reported more safety-, tobacco-, and alcohol-related risk behaviors compared to nonveteran students. For instance, compared to the nonveteran reference group, the ARR for past year smokeless tobacco use and physical fighting among for OEF/OIF veterans was 1.76 (95% CI = 1.31–2.35) and 1.48 (95% CI = 1.22–1.79) respectively. Veteran and nonveteran students display similar weight-related behaviors, though OEF/OIF veteran students were more likely to engage in strengthening exercises. Conclusions. There are specific health risk behaviors that are particularly relevant for veterans attending postsecondary institutions. As veterans enroll in postsecondary education, there is a unique window of opportunity for health promotion in this population.

Published: October 2011

Purpose. Investigate relations between demographic characteristics and submission method, Internet or paper, when physical activity behaviors are reported. Design. Observational. Setting. Metropolitan. Subjects. Adult women (N = 918) observed weekly for 2 years (total number of weekly reports, 44,963). Measures. Independent variables included age, race, education, income, employment status, and Internet skills. Dependent variables were method of submission (Internet or paper) and adherence. Analysis. Logistic regression to analyze weekly odds of submitting data online and meeting study adherence criteria. Model 1 investigated method of submission, model 2 analyzed meeting study's Internet adherence, and model 3 analyzed meeting total adherence regardless of submission method. Results. Whites, those with good Internet skills, and those reporting higher incomes were more likely to log online. Those who were white, older, and reported good Internet skills were more likely to be at least 75% adherent online. Older women were more likely to be adherent regardless of method. Employed women were less likely to log online or be adherent. Conclusion. Providing participants with multiple submission methods may reduce potential bias and provide more generalizable results relevant for future Internet-based research.
Recycling of aged ABS from real WEEE through ABS/PC blends in the ABS‐rich compositions
Authors: Barthes Marie‐Lise , Mantaux Olivier , Pedros Matthieu , Lacoste Eric , Dumon Michel 
Published: October 2011

AbstractRecycled aged acrylonitrile–butadiene–styrene (ABS) does not recover the impact strength of virgin ABS mainly due to polybutadiene degradation or the presence of flame retardants (FR). So, ABS/PC (polycarbonate) blends were elaborated to obtain a recycled material with resilience at least equivalent to neat ABS and within the range of composition of real waste electrical and electronic equipment (WEEE) deposits. ABS/PC blends were first made from virgin polymers to reach optimal processability and composition. Performing Charpy impact strength tests and morphological studies allowed us to evaluate influence of extrusion temperature and PC content on blends. Experimental results indicate that the impact strength of ABS/PC blends is higher when morphology is fibrillar‐like or co‐continuous. A virgin ABSFR/PC blend (70/30) with an impact strength greater than neat ABS has been obtained. But, with an equivalent composition, this result is not reached for recycled blends. So, to achieve efficient blends rich in recycled ABS, compatibilization is necessary. Recycled ABS/PC (70/30) blends compatibilized with 5% PP‐g‐MA prove to be more resilient than virgin ABS. However, a compatibilizing agent has a limited efficiency when it is used in the presence of a FR or subjected to a high residence time during injection. © 2011 Wiley Periodicals, Inc.

Preparation of new optically active heat‐resistant polyesters with improved solubility
Authors: Mehdipour‐Ataei Shahram , Ehsani Sara 
Published: October 2011

AbstractA novel diacid isophthalic acid bis‐(carboxyphenyl methyl) ester (IBE) containing optically active center and bulky pendent groups was successfully synthesized and used to prepare a series of aromatic polyesters. IBE was prepared via a reaction of R‐(–)‐mandelic acid with isophthaloyl chloride in the presence of potassium hydroxide. Direct polycondensation reactions of this monomer with various aromatic diols using para‐toluenesulfonyl chloride (p‐TsCl) via a Vilsmeier adduct resulted in the preparation of new optically active polyesters. Polyester showed reasonable molecular weight based on gel permeation chromatography (GPC) and inherent viscosity methods. Other physical and thermal properties of the polymers, including solubility, thermal behavior, thermal stability, and crystallinity in addition to optical activity, were studied. These heat‐resistant polymers showed optical activity and presence of bulky groups improved their solubility. According to the X‐ray diffraction patterns, the polyesters were almost amorphous. © 2011 Wiley Periodicals, Inc.

AbstractObjective:We assessed whether excessive daytime sleepiness (EDS) at baseline was associated with subsequent coronary heart disease (CHD) and stroke events.Methods:The Three City Study, a French population‐based multicenter prospective study, included 7,007 subjects aged ≥65 years with no personal history of CHD, stroke, or dementia, and self‐rated EDS as never, rare, regular, or frequent in response to a face‐to‐face questionnaire. Hazard ratios (HRs) for the first episode of stroke and CHD over 6 years were estimated using a Cox proportional hazards model with age as the time scale.Results:The mean age of the cohort was 73.7 years (standard deviation, 5.37), 63% were women, and 13.3% and 4.3% reported regular and frequent EDS, respectively. After a median follow‐up period of 5.1 years, 372 subjects experienced a first event, either stroke (122 subjects) or a CHD event (250 subjects). The increased risk of CHD and stroke was confined to the group with frequent EDS, and was 1.73× as much as in the group that reported never having EDS (HR, 1.73; 95% confidence interval [CI], 1.15–2.60), after adjustment for confounding and mediating factors. This association was seen in those without hypertension but not in those with hypertension at baseline (p for interaction = 0.01). Moreover, the association with frequent EDS was statistically significant for stroke (HR, 2.10; 95% CI, 1.13–3.89) but not for CHD (HR, 1.51; 95% CI, 0.87–2.61).Interpretation:The current study suggests that frequent EDS is independently associated with future vascular events and stroke in particular in healthy community‐dwelling elderly subjects.

Published: October 2011

AbstractFiber‐graded poly(propylene) was modified by polyester‐amide‐based dendritic nanostructures with the aim of improving its dyeability. Two different dendritic polymers were used and the dendritic nanostructures were formed in situ via reactive blending with maleic anhydride‐modified poly(propylene). Samples were chosen exploiting a 4‐component mixture design. Thermal, morphological, and rheological characterizations showed domains with different size and distribution were formed and primary properties of the dendritics determined the characteristics of the resulted domains. Morphological parameters were quantified by digital analysis of scanning electron microscope images. Thermal and rheological behavior also demonstrated good agreements with the inferred morphology of the formed dendritic domains. The modified samples were then dyed with dispersed dyestuffs. A variety of substantivities were obtained, and some of the modified samples showed a significant enhancement in dyeing properties. A predictive model was developed for K/S ratio, where K and S are absorption and scattering coefficients of the Kubelka‐Munk one constant theory, respectively. © 2011 Wiley Periodicals, Inc.

Process behavior of compatible polymer blends
Authors: Navarro R. , López J. , Parres F. , Ferrándiz S. 
Published: October 2011

AbstractIt is a common industrial practice to blend virgin polymer with the same polymer recycled from scrap plastic that, in general, has not undergone relevant degradation. In this article, the influence that incorporating recycled material has on injection processes, especially on the rheological behavior of the material was studied. With this aim in mind, a mixture of two materials with the same nature or composition and similar viscosity was used, which is the system that is most commonly seen in industry. The mixture studied is composed of virgin PP (polypropylene) typically found in injection processes, and recycled copolymer PP from scrap plastic. A complete characterization of the materials and applied existing models was carried out to predict the mechanical behavior of the mixtures. A model to predict the behavior of the mixtures during processing, based on the rheological characteristics of the materials used was developed. This predictive model has been experimentally validated using filling tests in injection molding machines, as well as by specific simulation software. © 2011 Wiley Periodicals, Inc.

Effect of hybridization and compatibilization on the mechanical properties of recycled polypropylene‐hemp composites
Authors: Ramezani Kakroodi Adel , Leduc Simon , Rodrigue Denis 
Published: October 2011

AbstractHemp fibers and particles, with different sizes and contents, were used to make hybrid composites based on recycled polypropylene (PP). In particular, the effect of maleated polypropylene (MAPP) addition on the morphology and mechanical properties is reported. The results show that better adhesion is obtained with MAPP addition. In general, fiber content and size had a substantial effect on the tensile, flexural, torsion, and impact properties of the resulting composites. Although, adding MAPP to the samples improved the impact strength of the composites, the values were always lower than neat PP. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
Contribution of matrix metalloproteinase 2 to joint destruction in group B Streptococcus–induced murine arthritis
Authors: Puliti Manuela , Momi Stefania , Falcinelli Emanuela , Gresele Paolo , Bistoni Francesco , Tissi Luciana 
Published: October 2011

AbstractObjectiveTo assess the role of matrix metalloproteinase 2 (MMP‐2) in the evolution of septic arthritis induced by group B streptococci (GBS) in mice.MethodsMice deficient in MMP‐2 (MMP‐2−/−) and wild‐type controls were injected intravenously with 1 × 107 colony‐forming units of type IV GBS (strain 1/82). Levels of MMP‐2, mortality rates, evolution of arthritis, bacterial clearance, joint histopathologic features, and production of cytokines and chemokines were examined in both experimental groups of mice on days 3, 6, and 9 after infection.ResultsMMP‐2 was produced during GBS infection. Disruption of the gene for MMP‐2 resulted in a decrease in the incidence and severity of arthritis, as demonstrated by both clinical and histologic findings, without affecting mortality rates. Amelioration of arthritis was accompanied by a dramatic reduction in the local production of interleukin‐1β (IL‐1β), IL‐6, macrophage inflammatory protein 1α (MIP‐1α), and MIP‐2 and a reduced bacterial burden.ConclusionMMP‐2, produced early during GBS infection in mice, is involved in the degradation of extracellular matrix components at the level of the joint. This degradation is the first step in a cascade of events (joint invasion by GBS, extravasation and accumulation of inflammatory cells, proinflammatory cytokine production), all of which contribute to the damage of articular tissue. Thus, MMP‐2 should be regarded as a potential therapeutic target in GBS‐induced arthritis.
Following the “community” thread from sociology to information behavior and informatics: Uncovering theoretical continuities and research opportunities
Authors: Veinot Tiffany C. , Williams Kate 
Published: October 2011

AbstractThe authors review five paradigms from the discipline of community sociology (functionalism, evolution, conflict, interactionism, and exchange) to assess their potential utility for understanding everyday life information behavior and technology use. Their analysis considers the ways in which each paradigm defines the concepts of community, information, and technology. It also explores the insights offered by each paradigm regarding relationships between community and both information and technology. Accordingly, the authors highlight the ways in which existing information behavior and informatics scholarship draws from similar conceptual roots. Key insights drawn from this research, as well as remaining gaps and research questions, are examined. Additionally, they consider the limitations of each approach. The authors conclude by arguing for the value of a vigorous research program regarding information behavior and technology use in communities, particularly that which takes the community as the central unit of analysis. They consider key questions that could drive such a research program, as well as potentially fruitful conceptual and methodological approaches for this endeavor.
Uses of explicit and implicit tags in social bookmarking
Authors: Arolas Enrique Estellés , Ladrón‐de‐Guevar Fernando González 
Published: October 2011

AbstractAlthough Web 2.0 contains many tools with different functionalities, they all share a common social nature. One tool in particular, social bookmarking systems (SBSs), allows users to store and share links to different types of resources, i.e., websites, videos, images. To identify and classify these resources so that they can be retrieved and shared, fragments of text are used. These fragments of text, usually words, are called tags. A tag that is found on the inside of a resource text is referred to as an obvious or explicit tag. There are also nonobvious or implicit tags, which don't appear in the resource text. The purpose of this article is to describe the present situation of the SBSs tool and then to also determine the principal features of and how to use explicit tags. It will be taken into special consideration which HTML tags with explicit tags are used more frequently.
