Establishing the Stages and Processes of Change for Weight Loss by Consensus of Experts

The present study aimed to establish, by a consensus of experts, the stages and processes of change for weight management in overweight and obese people. The first step involved developing two questionnaires aimed at assessing stages and processes of change for weight loss in overweight and obese people. The processes-ofchange questionnaire consisted of 12 subscales, and contained 107 items. A three-round Delphi study was carried out through a website, where participants were asked to give their opinion about the representativeness and clarity of the scale items. The stages-of-change questionnaire consisted of five items and was presented in the final round of the study. A team of 66 experts in the obesity field from 29 countries participated in the study. They were selected either because they belonged to the organizing committee of international associations related to obesity, or because of their research career. The required changes in the questionnaire were made according to the opinions of the participants. Some of these were the result of the group statistical response, whereas others were due to the suggestions made by the participants. A final version of the questionnaire consisting of 63 items was eventually obtained. The present study produced two questionnaires to assess stages and processes of change for weight management. The strength of the study lies in the consensus reached by the panel of experts in order to establish the required content of the questionnaires. The two measures provide useful tools for practitioners who wish to tailor weight-management interventions according to transtheoretical model constructs.

A signaling mechanism coupling netrin-1/deleted in colorectal cancer chemoattraction to SNARE-mediated exocytosis in axonal growth cones

Directed cell migration and axonal guidance are essential steps in neural development. Both processes are controlled by specific guidance cues that activate the signaling cascades that ultimately control cytoskeletal dynamics. Another essential step in migration and axonal guidance is the regulation of plasmalemma turnover and exocytosis in leading edges and growth cones. However, the cross talk mechanisms linking guidance receptors and membrane exocytosis are not understood. Netrin-1 is a chemoattractive cue required for the formation of commissural pathways. Here, we show that the Netrin-1 receptor deleted in colorectal cancer (DCC) forms a protein complex with the t-SNARE (target SNARE) protein Syntaxin-1 (Sytx1). This interaction is Netrin-1 dependent both in vitro and in vivo, and requires specific Sytx1 and DCC domains. Blockade of Sytx1 function by using botulinum toxins abolished Netrin-1-dependent chemoattraction of axons in mouse neuronal cultures. Similar loss-of-function experiments in the chicken spinal cord in vivo using dominant-negative Sytx1 constructs or RNAi led to defects in commissural axon pathfinding reminiscent to those described in Netrin-1 and DCC loss-of-function models. We also show that Netrin-1 elicits exocytosis at growth cones in a Sytx1-dependent manner. Moreover, we demonstrate that the Sytx1/DCC complex associates with the v-SNARE (vesicle SNARE) tetanus neurotoxin-insensitive vesicle-associated membrane protein (TI-VAMP) and that knockdown of TI-VAMP in the commissural pathway in the spinal cord results in aberrant axonal guidance phenotypes. Our data provide evidence of a new signaling mechanism that couples chemotropic Netrin-1/DCC axonal guidance and Sytx1/TI-VAMP SNARE proteins regulating membrane turnover and exocytosis.

Twist1 Is a TNF-Inducible Inhibitor of Clock Mediated Activation of Period Genes.

BACKGROUND: Activation of the immune system affects the circadian clock. Tumor necrosis factor (TNF) and Interleukin (IL)-1β inhibit the expression of clock genes including Period (Per) genes and the PAR-bZip clock-controlled gene D-site albumin promoter-binding protein (Dbp). These effects are due to cytokine-induced interference of E-box mediated transcription of clock genes. In the present study we have assessed the two E-box binding transcriptional regulators Twist1 and Twist2 for their role in cytokine induced inhibition of clock genes. METHODS: The expression of the clock genes Per1, Per2, Per3 and of Dbp was assessed in NIH-3T3 mouse fibroblasts and the mouse hippocampal neuronal cell line HT22. Cells were treated for 4h with TNF and IL-1β. The functional role of Twist1 and Twist2 was assessed by siRNAs against the Twist genes and by overexpression of TWIST proteins. In luciferase (luc) assays NIH-3T3 cells were transfected with reporter gene constructs, which contain a 3xPer1 E-box or a Dbp E-box. Quantitative chromatin immunoprecipitation (ChIP) was performed using antibodies to TWIST1 and CLOCK, and the E-box consensus sequences of Dbp (CATGTG) and Per1 E-box (CACGTG). RESULTS: We report here that siRNA against Twist1 protects NIH-3T3 cells and HT22 cells from down-regulation of Period and Dbp by TNF and IL-1β. Overexpression of Twist1, but not of Twist2, mimics the effect of the cytokines. TNF down-regulates the activation of Per1-3xE-box-luc, the effect being prevented by siRNA against Twist1. Overexpression of Twist1, but not of Twist2, inhibits Per1-3xE-box-luc or Dbp-E-Box-luc activity. ChIP experiments show TWIST1 induction by TNF to compete with CLOCK binding to the E-box of Period genes and Dbp. CONCLUSION: Twist1 plays a pivotal role in the TNF mediated suppression of E-box dependent transactivation of Period genes and Dbp. Thereby Twist1 may provide a link between the immune system and the circadian timing system.

Regulation of bistable ICEclc transfer in pseudomonas knackmussii B13

L'élément génétique intégratif et conjugatif auto-transférable de 103 kb qui se trouve dans le génome de Pseudomonas knackmussii B13 (ICEc/c) confère la capacité de dégrader le 3-chlorobenzoate et le 2-aminophénol. L'élément ICE c/c peut être transféré par conjugaison de la souche B13 à diverses bêta- et gamma- protéobactéries. Seule une sous-population de 3 à 5% des cellules transfère l'élément, les cellules dites "compétentes pour le transfert". L'acquisition de la compétence pour le transfert est vraisemblablement la conséquence d'une régulation bistable, conduisant une partie des cellules au transfert de l'élément ICE c/c tandis que, dans les autres, l'élément reste quiescent et ne se transfère pas. À ce jour, les mécanismes et les acteurs moléculaires qui régulent l'activation bistable de l'élément sont restés inconnus. Mon travail de doctorat visait à identifier les éléments bistables du régulon de la compétence pour le transfert et d'analyser les fondements moléculaires de la bistabilité de l'élément ICE c/c chez P. knackmussii. Le premier chapitre introduit le thème du transfert génétique horizontal avec un accent particulier sur les éléments intégratifs et conjugatifs (ICE) et ICEcIc. L'état actuel des connaissances sur l'organisation génétique, la régulation, l'intégration et le transfert de différents modèles de ICEs est exposé en détail. En outre, je m'étends sur les phénomènes d'hétérogénéité et de bistabilité phénotyplques, qu'on peut distinguer dans une population isogénique dans des conditions de culture homogènes, et qui sont susceptibles de jouer un rôle dans le transfert de l'élément ICE c/c, dans la mesure où il ne s'active et n'est transférable que dans une très petite sous-population de cellules. Dans le chapitre 2, je présente une analyse globale des régions promotrices minimales des gènes appartenant au régulon de la compétence pour le transfert de l'élément ICE c/c. Nous avons étudié les caractéristiques d'expression des promoteurs et, s'ils s'avéraient bistables, leur activation dans le temps par comparaison avec le mutant lntB13. Pour ce faire, nous avons utilisé des fusions de promoteurs avec des gènes rapporteurs et testé l'expression bistable chez P. knackmussii par microscopie à épifluorescence. Pour six promoteurs présentant une expression bistable, nous avons employé de la microscopie temporelle pour déterminer la chronologie de leur expression par rapport à Pint et PinR. Parmi eux, nous avons identifié deux gènes exprimés précocement et trois gènes exprimés tardivement dans le processus d'acquisition de la compétence de transfert. Dans le chapitre 3, j'expose une analyse d'expression génétique pour l'un des groupes de gènes dont la transcription est la plus élevée dans la région conservée de ICE c/c, les gènes orf81655-orf68241 contenus dans une région de 14 kb. Nous montrons d'abord que cet opéron fait partie du même régulon bistable que intB13 et inrR et analysons les caractéristiques génétiques qui conduisent à une transcription élevée. Nous étudions les fonctions biologiques de ce groupe de gènes par des délétlons ciblées et montrons que certaines d'entre elles empêchent le transfert de l'élément. Nous approfondissons la caractérlsatlon de I'orf8l655 en construisant une fusion transcrlptionnelle avec le gène codant pour la protéine fluorescente verte (egfp) (en utilisant le système minl-Tn5). L'expression de Vorf81655 dans des cellules individuelles est comparée au signal mesuré par hybridation in situ en fluorescence (FISH) sur le ARN messager du gène. En utilisant FISH, des délétlons du promoteur et de l'analyse directe de transcription, nous avons localisé la région promotrice du groupe de gènes. En outre, nous avons utilisé des mutations dirigées pour comprendre la bistabilité de cette région promotrice, caractérisée par une transcription très élevée et une traduction lente de l'ARN messager.  Dans le chapitre 4, nous nous efforçons de comprendre comment la bistabilité est générée au sein du régulon te de l'élément ICE c/c. Pour ce faire, nous avons tenté de reconstituer une expression bistable, dans un hôte qui ne présente pas de bistabilité naturellement, à partir d'éléments génétiques individuels. L'hôte choisi est Pseudomonas putida dans lequel nous avons introduit une copie unique de Pint, PinR ou PaipA fusionnés à la egfp, construits qui permettent d'observer l'apparition de bistabilité. Nous avons ensuite construit différents assemblages de composants génétiques de l'élément ICE c/c, en nous concentrant sur la région parA-inrR. En effet, nous avons pu démontrer qu'une expression bistable apparaît dans P. putida grâce à ces éléments en l'absence de l'élément ICE c/c complet. À noter que la plupart des construits génétiques activent PaipA ou P|,,R, mais qu'un seul recrée la bistabilité de Pint, ce qui suggère que la région parA-inrR permet à la fois d'engendrer la bistabilité et d'opérer la transition entre les promoteurs précoces et les promoteurs tardifs du régulon de la bistabilité. Dans le chapitre 5, nous concluons sur une discussion de la pertinence de nos résultats et sur de futures perspectives de recherche. -- The 103-kb self-transmissible integrative and conjugative element (ICE) of Pseudomonas knackmussii B13 (ICEc/c) confers the capacity to degrade 3- chlorobenzoate and 2-aminophenol. ICEc/c can be conjugated from strain B13 to a variety of Beta- and Gammaproteobacteria. Interestingly, ICE c/c transfer is observed in a subpopulatlon of cells (3-5%) only, the so-called 'transfer competent' cells. The formation of transfer competence (tc) is thought to be the consequence of a 'bistable' decision, which forces those cells to follow the developmental path which leads to ICEc/c transfer, whereas in others ICE c/c remains silent and does not transfer. So far, the mechanisms and molecular partners generating this bistable transfer activation in cells of P. knackmussii B13 remain mostly unidentified. This thesis aimed at understanding the extent of the tc bistability regulon and to dissect the molecular basis of bistabillty formation of ICEc/c in P. knackmussii. The first chapter is a general Introduction on horizontal gene transfer (HGT) with particular emphasis on ICEs and ICE c/c. The emphasis is made on the current knowledge about the HGT gene organization, regulation and specific integration and transfer aspects of the different ICEs models. Furthermore, I focus on the phenomena of phenotypic heterogeneity and bistability (the property of two distinguishable phenotypes existing within an isogenic population under homogeneous conditions), which may play a particular role in ICEc/c behaviour, since ICE activation and transfer only occurs in a very small subpopulation of cells. In Chapter Two, I focus on a global analysis of the different core promoters that might belong to the ICEc/c tc pathway regulon. We studied both expression patterns of ICEc/c promoters and, once being identified as "bistable", their temporal activation compared to that of intB13. In order to do this, we used promoter reporter fusions and tested blstability expression in P. knackmussii using epifluorescence microscopy. For the 6 promoters that showed bistable expression, we used time-lapse microscopy to study the timing of promoter expression in comparison to that of P,,,t or PlnR. We could establish two "early" and 3 "late" phase promoters in the process of transfer competence. In Chapter Three, I focused my attention on analysis of gene expression of one of the most highly transcribed gene clusters in the conserved core region of ICEc/c, a 14-kb gene cluster formed by the genes orf81655-orf68241. First we showed that this operon is part of the same bistability 'regulon' as intB13 and inrR, and analysed the genetic features that lead to high transcription. We studied the potential biological function of this cluster for ICE c/c by making specific gene deletions, showing that some interrupt ICEc/c transfer. We further analysed the orfdl655 promoter by constructing transcriptional egfp fusion reporter strains using the miniTn5 delivery system. Expression of the orf81655 promoter in single cells was compared to signals measured by Fluorescence In Situ Hybridization (FISH) on orfSl655 mRNA. We localized the promoter region of the gene cluster using FISH, promoter deletions, and by direct transcript analysis. We further used site-directed mutagenesis to understand the bistability character of the promoter region and the extremely high transcription but low translation from this mRNA. In Chapter Four, we set out to understand how bistability is generated in the tc pathway of ICEc/c. For this we tried rebuilding bistable expression from ICEc/c individual gene components in a host, which normally does not display bistability. As host we used P. putida without ICEc/c but with a single copy Pint-, PlnR- or PalpA- egfp fusion that enabled us to verify bistability formation. Subsequently, we built different assemblages of ICEc/c gene components, focusing on the parA-inrR region. Indeed, we found that bistable expression can be build from those components in P. putida without ICEc/c. Interestingly, most genetic constructs activated PaipA or PlnR, but only one resulted in bistable activation of PinT. This suggests that the parA-inrR region acts as a bistability "generator", but also as a bistability "relay" from early to late promoters in the tc pathway hierarchy. In the final fifth chapter, we conclude with a discussion of the relevance of the present thesis and the resulting perspectives for future studies.

El enfoque metodológico usado ha sido cualitativo-fenomenológico En lo que se refiere a los criterios de evaluación, dos han sido los utilizados en este estudio: la utilidad percibida por el profesorado y la transferibilidad del conocimiento elaborado en el curso.

p21 as a Transcriptional Co-Repressor of S-Phase and Mitotic Control Genes

It has been previously described that p21 functions not only as a CDK inhibitor but also as a transcriptional co-repressor in some systems. To investigate the roles of p21 in transcriptional control, we studied the gene expression changes in two human cell systems. Using a human leukemia cell line (K562) with inducible p21 expression and human primary keratinocytes with adenoviral-mediated p21 expression, we carried out microarray-based gene expression profiling. We found that p21 rapidly and strongly repressed the mRNA levels of a number of genes involved in cell cycle and mitosis. One of the most strongly down-regulated genes was CCNE2 (cyclin E2 gene). Mutational analysis in K562 cells showed that the N-terminal region of p21 is required for repression of gene expression of CCNE2 and other genes. Chromatin immunoprecipitation assays indicated that p21 was bound to human CCNE2 and other p21-repressed genes gene in the vicinity of the transcription start site. Moreover, p21 repressed human CCNE2 promoter-luciferase constructs in K562 cells. Bioinformatic analysis revealed that the CDE motif is present in most of the promoters of the p21-regulated genes. Altogether, the results suggest that p21 exerts a repressive effect on a relevant number of genes controlling S phase and mitosis. Thus, p21 activity as inhibitor of cell cycle progression would be mediated not only by the inhibition of CDKs but also by the transcriptional down-regulation of key genes.

Macroporous Scaffolds for Bone Engineering. Studies on Cell Culture and Ectopic Bone Formation

Bone engineering is a rapidly developing area of reconstructive medicine where bone inducing factors and/or cells are combined with a scaffold material to regenerate the structure and function of the original tissue. The aim of this study was to compare the suitability of different macroporous scaffold types for bone engineering applications. The two scaffold categories studied were a) the mechanically strong and stable titanium fiber meshes and b) the elastic and biodegradable porous polymers. Furthermore, bioactive modifications were applied to these basic scaffold types, and their effect on the osteogenic responses was evaluated in cell culture and ectopic bone formation studies. The osteogenic phenotype of cultured cell-scaffold constructs was heightened with a sol-gel derived titania coating, but not with a mixed titania-silica coating. The latter coating also resulted in delayed ectopic bone formation in bone marrow stromal cell seeded scaffolds. However, the better bone contact in early implantation times and more even bone tissue distribution at later times indicated enhanced osteoconductivity of both the coated scaffold types. Overall, the most promising bone engineering results were obtained with titania coated fiber meshes. Elastic and biodegradable poly(ε-caprolactone/D,L-lactide) based scaffolds were also developed in this study. The degradation rates of the scaffolds in vitro were governed by the hydrophilicity of the polymer matrix, and the porous architecture was controlled by the amount and type of porogen used. A continuous phase macroporosity was obtained using a novel CaCl2 • 6H2O porogen. Dynamic culture conditions increased cell invasion, but decreased cell numbers and osteogenicity, within the scaffolds. Osteogenic differentiation in static cultures and ectopic bone formation in cell seeded scaffolds were enhanced in composites, with 30 wt-% of bioactive glass filler.

A chromosomal insertion toolbox for promoter probing, mutant complementation and pathogenicity studies in Ralstonia solanacearum

We describe here the construction of a delivery system for stable and directed insertion of gene constructs in a permissive chromosomal site of the bacterial wilt pathogen Ralstonia solanacearum. The system consists of a collection of suicide vectors the Ralstonia chromosome (pRC) series that carry an integration element flanked by transcription terminators and two sequences of homology to the chromosome of strain GMI1000, where the integration element is inserted through a double recombination event. Unique restriction enzyme sites and a GATEWAY cassette enable cloning of any promoter::gene combination in the integration element. Variants endowed with different selectable antibiotic resistance genes and promoter::gene combinations are described. We show that the system can be readily used in GMI1000 and adapted to other R. solanacearum strains using an accessory plasmid. We prove that the pRC system can be employed to complement a deletion mutation with a single copy of the native gene, and to measure transcription of selected promoters in monocopy both in vitro and in planta. Finally, the system has been used to purify and study secretion type III effectors. These novel genetic tools will be particularly useful for the construction of recombinant bacteria that maintain inserted genes or reporter fusions in competitive situations (i.e., during plant infection).

Feedback i oportunitats de millora: una avaluació orientada a l"aprenentatge actiu

This paper analyzes an innovative experience of formative assessment aimed at improving the teaching of Statistics, which could be easily extrapolated to other studies. We detail the implementation of the double correction, consisting of correcting students' work twice. With the first correction, carried out by classmates according to a rubric developed by the academic, possible errors or deficiencies are discovered, and students are provided with a feedback that allows them to correct and improve their work before being graded by the teacher; whereas in the second correction of the work, once upgraded, the professor evaluates and grades the work. As a result, there is a significant improvement in the quality of students" works, and an active learning from their own mistakes. Both contents and competencies are reinforced by the experience.

A measurement framework for quality health care for adolescents in hospital.

PURPOSE: Despite growing interest in measurement of health care quality and patient experience, the current evidence base largely derives from adult health settings, at least in part because of the absence of appropriately developed measurement tools for adolescents. To rectify this, we set out to develop a conceptual framework and a set of indicators to measure the quality of health care delivered to adolescents in hospital. METHODS: A conceptual framework was developed from the following four elements: (1) a review of the evidence around what young people perceive as "adolescent-friendly" health care; (2) an exploration with adolescent patients of the principles of patient-centered care; (3) a scoping review to identify core clinical practices around working with adolescents; and (4) a scoping review of existing conceptual frameworks. Using criteria for indicator development, we then developed a set of indicators that mapped to this framework. RESULTS: Embedded within the notion of patient- and family-centered care, the conceptual framework for adolescent-friendly health care (quality health care for adolescents) was based on the constructs of experience of care (positive engagement with health care) and evidence-informed care. A set of 14 indicators was developed, half of which related to adolescents' and parents' experience of care and half of which related to aspects of evidence-informed care. CONCLUSIONS: The conceptual framework and indicators of quality health care for adolescents set the stage to develop measures to populate these indicators, the next step in the agenda of improving the quality of health care delivered to adolescents in hospital settings.

Assessment in CLIL

The aim of this talk is to explore assessment in higher education and support for learners during their academic education. It investigates the assessment methods that provide success for universities and learners. Universities which implement CLIL should assess learners who would like to attend a programme in English without taking account of their English language qualifications. This assessment should be done in writing, listening and comprehension, speaking and reading and comprehension. In the literature, formative and summative assessments are considered. Formative assessment is ongoing, 'more complex as its intention is to be directly diagnostics with a view to immediately impacting on learner's next steps' (Coyle et al, 2010). Summative assessment occurs at the end of the term or course. McKay, 2006 divides assessment into three phases: design, operationalization and administration phase. If these three phases can't be embedded in the classroom as they are, they can be introduced as a set of questions; why?, how? and what?

Simulated Patient as Co-facilitators: Benefits and Challenges of the Interprofessional Team OSCE (Submission #9350).

Hypothesis: The quality of care for chronic patients depends on the collaborative skills of the healthcare providers.1,2 The literature lacks reports of the use of simulation to teach collaborative skills in non-acute care settings. We posit that simulation offers benefits for supporting the development of collaborative practice in non-acute settings. We explored the benefits and challenges of using an Interprofessional Team - Objective Structured Clinical Examination (IT-OSCE) as a formative assessment tool. IT-OSCE is an intervention which involves an interprofessional team of trainees interacting with a simulated patient (SP) enabling them to practice collaborative skills in non-acute care settings.5 A simulated patient are people trained to portray patients in a simulated scenario for educational purposes.6,7 Since interprofessional education (IPE) ultimately aims to provide collaborative patient-centered care.8,9 We sought to promote patient-centeredness in the learning process. Methods: The IT-OSCE was conducted with four trios of students from different professions. The debriefing was co-facilitated by the SP with a faculty. The participants were final-year students in nursing, physiotherapy and medicine. Our research question focused on the introduction of co-facilitated (SP and faculty) debriefing after an IT-OSCE: 1) What are the benefits and challenges of involving the SP during the debriefing? and 2) To evaluate the IT-OSCE, an exploratory case study was used to provide fine grained data 10, 11. Three focus groups were conducted - two with students (n=6; n=5), one with SPs (n=3) and one with faculty (n=4). Audiotapes were transcribed for thematic analysis performed by three researchers, who found a consensus on the final set of themes. Results: The thematic analysis showed little differentiation between SPs, student and faculty perspectives. The analysis of transcripts revealed more particularly, that the SP's co-facilitation during the debriefing of an IT-OSCE proved to be feasible. It was appreciated by all the participants and appeared to value and to promote patient-centeredness in the learning process. The main challenge consisted in SPs feedback, more particularly in how they could report accurate observations to a students' group rather than individual students. Conclusion: In conclusion, SP methodology using an IT-OSCE seems to be a useful and promising way to train collaborative skills, aligning IPE, simulation-based team training in a non-acute care setting and patient-centeredness. We acknowledge the limitations of the study, especially the small sample and consider the exploration of SP-based IPE in non-acute care settings as strength. Future studies could consider the preparation of SPs and faculty as co-facilitators. References: 1. Borrill CS, Carletta J, Carter AJ, et al.

International journal of engineering education

This work presents an analysis of the assessment tools used by professors at the Universitat Politécnica de Catalunya to assess the generic competencies introduced in the Bachelor’s Degrees in Engineering. In order to conduct this study, a survey was designed and administered anonymously to a sample of the professors most receptive to educational innovation at their own university. All total, 80 professors responded to this survey, of whom 26% turned out to be members of the university’s own evaluation innovation group (https://www.upc.edu/rima/grups/grapa), GRAPA. This percentage represents 47% of the total GRAPA membership, meaning that nearly half of the professors most concerned about evaluation at the university chose to participate. The analysis of the variables carried out using the statistical program SPSS v19 shows that for practically 49% of those surveyed, rubrics are the tools most commonly used to assess generic competencies integrated in more specific ones. Of those surveyed, 60% use them either frequently or always. The most frequently evaluated generic competencies were teamwork (28%), problem solving (26%), effective oral and written communication (24%) and autonomous learning (13%), all of which constitute commonly recognized competencies in the engineering profession. A two-dimensional crosstabs analysis with SPSS v19 shows a significant correlation (Asymp. Sig. 0.001) between the type of tool used and the competencies assessed. However, no significant correlation was found between the type of assessment tool used and the type of subject, type of evaluation (formative or summative), frequency of feedback given to the students or the degree of student satisfaction, and thus none of these variables can be considered to have an influence on the kind of assessment tool used. In addition, the results also indicate that there are no significant differences between the instructors belonging to GRAPA and the rest of those surveyed
