RP 59500 prophylaxis of experimental endocarditis due to erythromycin-susceptible and -resistant isogenic pairs of viridans group streptococci.

RP 59500 is a new injectable streptogramin composed of two synergistic components (quinupristin and dalfopristin) which are active against a number of erythromycin-susceptible and -resistant gram-positive bacteria. The following experiments investigate the ability of RP 59500 to prevent experimental endocarditis due to either of two erythromycin-susceptible streptococcal isolates or their constitutively erythromycin-resistant Tn916 delta E transconjugants. RP 59500 had low MICs (0.125 to 0.5 mg/liter) for all four test organisms and was substantially bactericidal in vitro. Rats with catheter-induced aortic vegetations were given single-dose antibiotic prophylaxis 30 to 60 min before bacterial inoculation through a computerized pump system which permitted the simulation of drug kinetics for humans produced by either 7 mg of RP 59500 per kg of body weight or 1 g of vancomycin. Single-dose RP 59500 prophylaxis successfully prevented endocarditis due to both the erythromycin-susceptible parent strains and their erythromycin-resistant derivatives in rats challenged with the minimal inoculum infecting 90% of controls. In addition, RP 59500 also prevented infection in animals challenged with fivefold-larger inocula of the erythromycin-susceptible parent strains. Vancomycin successfully prevented endocarditis due to any of the four test organisms. These results underline the in vivo efficacy of RP 59500 against both erythromycin-susceptible and -resistant streptococci. Such good results against the resistant strains would not be expected with erythromycin or clindamycin, which are the standard macrolidelincosamide-streptogramin antibiotics used for endocarditis prophylaxis in humans. An oral form of RP 59500 which might advantageously replace some of the older prophylactic regimens is currently being developed.

A study of personality in children aged 8-12 years: Comparing self- and partents' ratings

This study was designed to investigate personality development with children aged 8 to 12. For this purpose, Children's self-perceptions were compared to parent's ratings. 506 children and their parents completed a selection of 38 questions from the Hierarchical Personality Inventory for Children (HiPIC). Results showed an age-related increase in the structural congruence of children's ratings compared to parents' ratings and a highly significant increase in the reliabilities of both parents' and children's assessments. The mean correlation between the children's self-descriptions and parents' ratings were higher for Conscientiousness and Imagination than for Extraversion, Benevolence and Emotional Stability and significantly increased with the children's age. Mean-levels decreased with age for Imagination in parents' ratings and for Benevolence, Conscientiousness, and Imagination, in children's ratings. This study showed that personality development from 8 to 12 years goes along with an increase in the agreement between the children's self-perceptions and the parents' perceptions of the children's personality.

Photodynamic Diagnosis in Non-Muscle-Invasive Bladder Cancer

Objective This paper reviews the development and clinical validation of photodynamic diagnosis (PDD) of bladder cancer. Methods The authors reviewed the literature on the development of PDD, in particular the evidence for the clinical efficacy of hexaminolevulinate PDD in the diagnosis of bladder cancer. Results After initial work on ultraviolet cystoscopy following oral tetracycline, the focus of PDD research shifted to the use of synthetic porphyrins. First, the prodrug delta-aminolevulinic acid (ALA) was shown to cause a transient but significant accumulation of protoporphyrin IX (PpIX) in malignant or premalignant bladder tissue. Excitation by blue light leads to PpIX fluorescence (red), which distinguishes tumour from normal tissue (blue). Hexaminolevulinate (HAL, Hexvix), an ester of ALA, was then developed and has greater bioavailability and stability than the parent compound. It has been approved for clinical use in the diagnosis of bladder cancer. Clinical studies have shown that HAL PDD detects tumours, including carcinoma in situ (CIS), that are missed by conventional white-light cystoscopy. Conclusions HAL PDD is a valuable aid to the detection of bladder tumours, including CIS.

Nestling detectability affects parental feeding preferences in a cavity-nesting bird

In many avian species, nestlings have evolved striking plumage, behaviours and mouth colours to obtain a greater share of parental investment. Studies revealing parental feeding preferences for nestlings with red gapes have proposed that red mouth colour in songbirds can act as a signal of nestling need or condition. Alternative hypotheses suggest that bright nestling mouths in cavity-nesting birds evolved to increase nestling detectability by the parents. We tested whether nestling mouth colour affects parental feeding preferences in great tits, Pants major L. In broods of six young, we experimentally painted mouth gapes and flanges either red or yellow and tested the effect of mouth colour on nestlings' mass gain under two lighting conditions. In nests with high luminosity, there was no significant effect of mouth colour on mass gain. In nests with low luminosity, nestlings with red gapes and flanges gained less mass than nestlings with red gapes and yellow flanges or both yellow gapes and flanges. Our results suggest that, in nests with low luminosity, red mouths decreased nestling detectability to the feeding parents and support the hypothesis that poor luminosity in nesting cavities can select for pale mouths. Overall, our results do not support the hypothesis that red mouth colour signals nestling need or condition to parent great tits.

Características de la familia de origen y de la familia formada por las médicas y los médicos de familia de Andalucía.

BACKGROUND The origin and formed family characteristics are related to physician's professional career. The purpose of this study was to know and compare by sex the characteristics of the origin family and formed family of women and men family physician in Andalusia. METHODS Cross sectional and multicenter study. SETTING Urban primary health care centres from Andalusian province capitals. PARTICIPANTS Physician of primary health care centres. INCLUSION CRITERIA at least one year using computerized medical history with the same quota patients. Multistage random sample, 88 primary health care centres and 500 physicians, 50% of both sexes (alpha=5%, power=90%, precision=15%). Postal auto administrated questionnaire. VARIABLES sex, age, tutor of resident in family medicine, last father's activity, last mother's activity, number of brothers or sisters, family situation, last couple's activity (if any), to have or not children. RESULTS 73.6 % responses. In no responses there weren't differences of sex neither tutor of resident in family medicine. Mean age: women physicians 49.5 +/- 4.3 and men physician 51.3 +/- 4.9 (p= or < 0.005). Postgraduate formation in family medicine: 42.2% of women and 33.3% of men (p=0.016). Live alone: 6.1% of women physician and 2.7% men physician (p=0.005). Live alone with children 9.9% of women and 2.2% of men (p=0.005). 16.5% of women and 10.2% of men don t have children (p=0.077). 21.1% of men physician s couples work only at home vs. 0.1% of women physician s couples (p= or < 0.005). 46% of women physician s couples is also physician vs. 22% of men physician s couples (p= or < 0.005). No significant differences registered in parent s activities neither in the number of brother or sisters. CONCLUSION There are no significant differences in physician s origin family. However important differences in the characteristics of formed family are observed in both sexes.

Profiling of 19-norandrosterone sulfate and glucuronide in human urine: implications in athlete's drug testing.

19-Norandrosterone (19-NA) as its glucuronide derivative is the target metabolite in anti-doping testing to reveal an abuse of nandrolone or nandrolone prohormone. To provide further evidence of a doping with these steroids, the sulfoconjugate form of 19-norandrosterone in human urine might be monitored as well. In the present study, the profiling of sulfate and glucuronide derivatives of 19-norandrosterone together with 19-noretiocholanolone (19-NE) were assessed in the spot urines of 8 male subjects, collected after administration of 19-nor-4-androstenedione (100mg). An LC/MS/MS assay was employed for the direct quantification of sulfoconjugates, whereas a standard GC/MS method was applied for the assessment of glucuroconjugates in urine specimens. Although the 19-NA glucuronide derivative was always the most prominent at the excretion peak, inter-individual variability of the excretion patterns was observed for both conjugate forms of 19-NA and 19-NE. The ratio between the glucuro- and sulfoconjugate derivatives of 19-NA and 19-NE could not discriminate the endogenous versus the exogenous origin of the parent compound. However, after ingestion of 100mg 19-nor-4-androstenedione, it was observed in the urine specimens that the sulfate conjugates of 19-NA was detectable over a longer period of time with respect to the other metabolites. These findings indicate that more interest shall be given to this type of conjugation to deter a potential doping with norsteroids.

A combination of ascorbic acid and α-tocopherol to test the effectiveness and safety in the fragile X syndrome: study protocol for a phase II, randomized, placebo-controlled trial.

BACKGROUND Fragile X syndrome (FXS) is an inherited neurodevelopmental condition characterised by behavioural, learning disabilities, physical and neurological symptoms. In addition, an important degree of comorbidity with autism is also present. Considered a rare disorder affecting both genders, it first becomes apparent during childhood with displays of language delay and behavioural symptoms.Main aim: To show whether the combination of 10 mg/kg/day of ascorbic acid (vitamin C) and 10 mg/kg/day of α-tocopherol (vitamin E) reduces FXS symptoms among male patients ages 6 to 18 years compared to placebo treatment, as measured on the standardized rating scales at baseline, and after 12 and 24 weeks of treatment.Secondary aims: To assess the safety of the treatment. To describe behavioural and cognitive changes revealed by the Developmental Behaviour Checklist Short Form (DBC-P24) and the Wechsler Intelligence Scale for Children-Revised. To describe metabolic changes revealed by blood analysis. To measure treatment impact at home and in an academic environment. METHODS/DESIGN A phase II randomized, double-blind pilot clinical trial. SCOPE male children and adolescents diagnosed with FXS, in accordance with a standardized molecular biology test, who met all the inclusion criteria and none of the exclusion criteria. INSTRUMENTATION clinical data, blood analysis, Wechsler Intelligence Scale for Children-Revised, Conners parent and teacher rating scale scores and the DBC-P24 results will be obtained at the baseline (t0). Follow up examinations will take place at 12 weeks (t1) and 24 weeks (t2) of treatment. DISCUSSION A limited number of clinical trials have been carried out on children with FXS, but more are necessary as current treatment possibilities are insufficient and often provoke side effects. In the present study, we sought to overcome possible methodological problems by conducting a phase II pilot study in order to calculate the relevant statistical parameters and determine the safety of the proposed treatment. The results will provide evidence to improve hyperactivity control and reduce behavioural and learning problems using ascorbic acid (vitamin C) and α-tocopherol (vitamin E). The study protocol was approved by the Regional Government Committee for Clinical Trials in Andalusia and the Spanish agency for drugs and health products. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT01329770 (29 March 2011).

Prise en charge d'adolescents souffrant d'anorexie mentale: le rôle des parents, une approche basée sur l'évidence [Adolescents with an eating disorder: an evidence-based approach on the role of parents].

L'adolescence est une période de grands changements et de ce fait potentiellement de grande vulnérabilité. Ainsi, les bouleversements physiques et psychiques induits par les processus pubertaires sont un terrain propice à l'émergence d'un trouble des conduites alimentaires (TCA). La thérapie familiale selon Maudsley, ou family based treatment (FBT), a émergé en parallèle aux avancées neurobiologiques, qui confirment une origine multifactorielle des troubles du comportement alimentaire. Cette thérapie replace les parents au centre de la prise en charge des adolescents souffrant d'un TCA avec comme grand atout, une approche basée sur l'évidence scientifique. Adolescence is a time of great change and therefore, potentially of great vulnerability. Thus, physical and psychological changes induced by pubertal processes are fertile ground for the emergence of an eating disorder (ED). Family therapy according to Maudsley or "family based treatment" (FBT) has emerged in parallel with neurobiological advances confirming a multifactorial origin of eating disorders. This therapy places parents at the centre of care for adolescents with EDs. Its great asset is the evidence-based approach underpinning the therapy.

Sharing competences in strategic alliances: a case study of the Cosan and Shell biofuel venture

In a competitive world, the way a firm establishes its organizational arrangements may determine the enhancement of its core competences and the possibility of reaching new markets. Firms that find their skills to be applicable in just one type of market encounter constraints in expanding their markets, and through alliances may find a competitive form of value capture. Hybrid forms of organization appear primarily as an alternative to capturing value and managing joint assets when the market and hierarchy modes do not present any yields for the firm's competitiveness. As a result, this form may present other challenging issues, such as the allocation of rights and principal-agent problems. The biofuel market has presented a strong pattern of changes over the last 10 years. New intra-firm arrangements have appeared as a path to participate or survive among global competition. Given the need for capital to achieve better results, there has been a consistent movement of mergers and acquisitions in the Biofuel sector, especially since the 2008 financial crisis. In 2011 there were five major groups in Brazil with a grinding capacity of more than 15 million tons per year: Raízen (joint venture formed by Cosan and Shell), Louis Dreyfus, Tereos Petrobras, ETH, and Bunge. Major oil companies have implemented the strategy of diversification as a hedge against the rising cost of oil. Using the alliance of Cosan and Shell in the Brazilian biofuel market as a case study, this paper analyses the governance mode and challenging issues raised by strategic alliances when firms aim to reach new markets through the sharing of core competences with local firms. The article is based on documentary research and interviews with Cosan's Investor Relations staff, and examines the main questions involving hybrid forms through the lens of the Transaction Cost Economics (TCE), Agency Theory, Resource Based View (RBV), and dynamic capabilities theoretical approaches. One focal point is knowledge "appropriability" and the specific assets originated by the joint venture. Once the alliance is formed, it is expected that competences will be shared and new capabilities will expand the limits of the firm. In the case studied, Cosan and Shell shared a number of strategic assets related to their competences. Raízen was formed with economizing incentives, as well to continue marshalling internal resources to enhance the company's presence in the world energy sector. Therefore, some challenges might be related to the control and monitoring agents' behavior, considering the two-part organism formed by distinctive organizational culture, tacit knowledge, and long-term incentives. The case study analyzed illustrates the hybrid arrangement as a middle form for organizing the transaction: neither in the market nor in the hierarchy mode, but rather a more flexible commitment agreement with a strategic central authority. The corporate governance devices are also a challenge, since the alignment between the parent companies in the joint ventures is far more complex. These characteristics have led to an organism with bilateral dependence, offering favorable conditions for developing dynamic capabilities. However, these conditions might rely on the partners' long-term interest in the joint venture.

"Quitter le milieu" Une étude sociologique des processus de désaffiliation religieuse du milieu évangélique suisse

La thématique des désaffiliations religieuses du milieu évangélique est le parent pauvre des études faites jusqu'à ce jour sur ce courant religieux. En effet, l'accent est généralement mis sur son développement en termes d'affiliation faisant alors l'impasse sur les pertes qu'il connaît pourtant. De plus, la question des désaffiliations religieuses est un angle d'approche sociologique particulièrement fécond pour étudier les groupes religieux en permettant, entre autres, de cerner plus en profondeur leur identité, les mécanismes qui favorisent leur pérennisation, mais aussi leur rapport à la société environnante. Dans ce travail, qui s'inscrit en sociologie des religions et qui puise autant dans la littérature sur les désaffiliations religieuses que dans celle des désengagements militants, l'analyse s'est focalisée sur les processus de désengagement au niveau microsociologique : quels sont les motifs qui président les désaffiliations, comment se déroulent ces dernières, quels effets ont-elles sur l'individu en termes identitaires et comment sont-elles perçues par ceux qui restent ? Ces principales questions ont permis de (re] questionner des éléments constitutifs de l'engagement évangélique : les processus de socialisation ; la structuration des liens intragroupe développés par le milieu et son rapport à l'extérieur ; son système normatif; son système de représentation du monde et la démarche religieuse qu'il valorise, qui sont autant d'aspects qui jouent un rôle dans les processus de désaffiliation. Plus précisément, ces éléments agissent en tant que mécanismes de rétention tant sociaux que psychologiques compliquant ainsi le désengagement. Cette thèse s'est construite sur dix-sept entretiens semi directifs menés auprès de personnes ayant grandi pour la plupart dans une famille évangélique et qui ont décidé, un jour, de ne plus fréquenter ce milieu religieux. Pour élargir la perspective analytique et pour permettre de comprendre et d'expliquer les processus de désaffiliation en lien avec le groupe quitté, un ensemble de septante-huit entretiens semi directifs et de mille cent questionnaires standardisés de membres d'Eglises évangéliques a été mobilisé. Partant des logiques du désengagement, cette thèse affine les connaissances actuelles sur l'évangélisme dans le contexte de la modernité, grâce à l'éclairage inédit qu'elle lui donne. Elle développe également le champ des connaissances sur les désaffiliations religieuses en lui fournissant un nouvel exemple de cas tout en lui offrant une autre façon de théoriser les sorties de groupes religieux qui valorisent un engagement de type militant. - Religious disaffiliations from the evangelical milieu have not yet been investigated. Indeed, former studies have usually focused on the development of the milieu by looking at conversions. However, it appears that the study of the disaffiliation processes may not only give results on the reasons and experiences of those disaffiliating, but also shed light on the attributes and the development of the evangelical milieu itself. The main goal of this thesis was to fill this gap in the literature. From a microsociological approach, this thesis sought to answer the following central question : Why, how and with what effects do individuals leave the evangelical milieu and how is this phenomenon perceived, interpreted and managed by the individuals who leave the evangelical community and by the members of the evangelical milieu? These questions enabled me to investigate the functioning of the evangelical milieu : its processes of socialization ; internal and external relationships ; normative system ; belief system or its religious engagement. This set of aspects can influence and complicate the processes of disaffiliation. The analysis of religious disaffiliation was based on seventeen qualitative interviews with former members of evangelical chrurches who decided, one day, not to attend an evangelical church anymore and who question more or less strongly the « system of evangelical thought ». Seventy-eight qualitative interviews with members of evangelical free churches and a representative survey with members of evangelical free churches (N = 1100] completed the analysis and inserted the individual disengagement in the « milieu's logics ». This thesis complements and enriches the literature on evangelism as well as on religious disaffiliation in general.

Effectiveness of a pediatric palliative home care team as experienced by parents and health care professionals.

OBJECTIVES: Little data are available on palliative home care for children. The objective of this study was to evaluate the effectiveness of a specialized pediatric palliative home care team (PPHCT) as experienced by parents and health care professionals (HCPs). METHODS: Parents and HCPs involved in the care of terminally ill children who died and whom the PPHCT was in charge of were surveyed with questionnaires focusing on satisfaction with the PPHCT, satisfaction with the course of the dying phase, and the development of anxiety, depression, and prolonged grief disorder. RESULTS: Forty-three parent dyads participated (return rate, 88%). Satisfaction with the PPHCT scored a median of 10 (numeric rating scale, 0-10). The child's death was predominantly experienced as very peaceful (median, 9); 71% died at home. According to parents, involvement of the PPHCT led to highly significant (p<0.001) improvements in the children's symptoms and quality of life, as well as in aspects of communication and administrative barrier reduction. Anxiety was detected in 25% of parents, depression in 19%, and prolonged grief disorder in 13%. HCPs (return rate, 83%) evaluated all investigated care domains (particularly cooperation/communication/family support) as being significantly improved (p<0.001). Thirty-five percent of HCPs felt uncertain concerning pediatric palliative care; 79% would welcome specific training opportunities. CONCLUSIONS: Involvement of a PPHCT is experienced as a substantial improvement of care by parents and HCPs. Coordination of palliative care during the last phase of life appears to be an important quality factor for the home care of dying children and their families.

Comprehensive analysis of Arabidopsis expression level polymorphisms with simple inheritance.

In Arabidopsis thaliana, gene expression level polymorphisms (ELPs) between natural accessions that exhibit simple, single locus inheritance are promising quantitative trait locus (QTL) candidates to explain phenotypic variability. It is assumed that such ELPs overwhelmingly represent regulatory element polymorphisms. However, comprehensive genome-wide analyses linking expression level, regulatory sequence and gene structure variation are missing, preventing definite verification of this assumption. Here, we analyzed ELPs observed between the Eil-0 and Lc-0 accessions. Compared with non-variable controls, 5' regulatory sequence variation in the corresponding genes is indeed increased. However, approximately 42% of all the ELP genes also carry major transcription unit deletions in one parent as revealed by genome tiling arrays, representing a &gt;4-fold enrichment over controls. Within the subset of ELPs with simple inheritance, this proportion is even higher and deletions are generally more severe. Similar results were obtained from analyses of the Bay-0 and Sha accessions, using alternative technical approaches. Collectively, our results suggest that drastic structural changes are a major cause for ELPs with simple inheritance, corroborating experimentally observed indel preponderance in cloned Arabidopsis QTL.
