Portraying innovation in the public service of Brazil: Frameworks, systematization and characterization

ABSTRACT Innovation is essential for improving organizational performance in both the private and public sectors. This article describes and analyzes the 323 innovation experiences of the Brazilian federal public service that received prizes during the 16 annual competitions (from 1995 to 2012) of the Award for Innovation in Federal Public Management held by the Brazilian National School of Public Administration (ENAP). It is a qualitative and quantitative study in which were employed as categories for analysis the four types of innovation defined in the Copenhagen Manual: product, process, organizational and communication. The survey results allow us to affirm that there is innovation in the public sector, in spite of the skepticism of some researchers and the incipient state of theoretical research on the subject. It was possible to observe that organizational innovation was the one with the highest number of award- -winning experience, followed respectively by process, communication and product innovation, with citizen services and improvement of work processes being the main highlights. The results showed that, although the high incidence of innovation occurs at the national level, a significant number of innovations also occur at the local level, probably because many organizations of the federal government have their actions spread only at this level of government. Concerning the innovative area, health and education predominate, with almost 33% of initiatives, which can be explained by capillarity of these areas and the fact that both maintain a strong interaction with the user. The contributions of this work include the use of theoretical model of innovation analysis in the public sector in Brazil still upcoming, and the systematization of knowledge in empirical basis for this innovation. In this sense, it also contributes to the development of the theory with the presentation of evidence that the characteristics, determinants and consequences of innovation in the public sector differ not only from innovation in the industry, but also from innovation in services in the private sector.

Markers of atherosclerosis and of inflammation for prediction of coronary heart disease in older adults

BACKGROUND: Several markers of atherosclerosis and of inflammation have been shown to predict coronary heart disease (CHD) individually. However, the utility of markers of atherosclerosis and of inflammation on prediction of CHD over traditional risk factors has not been well established, especially in the elderly. METHODS: We studied 2202 men and women, aged 70-79, without baseline cardiovascular disease over 6-year follow-up to assess the risk of incident CHD associated with baseline noninvasive measures of atherosclerosis (ankle-arm index [AAI], aortic pulse wave velocity [aPWV]) and inflammatory markers (interleukin-6 [IL-6], C-reactive protein [CRP], tumor necrosis factor-a [TNF-a]). CHD events were studied as either nonfatal myocardial infarction or coronary death ("hard" events), and "hard" events plus hospitalization for angina, or the need for coronary-revascularization procedures (total CHD events). RESULTS: During the 6-year follow-up, 283 participants had CHD events (including 136 "hard" events). IL-6, TNF-a and AAI independently predicted CHD events above Framingham Risk Score (FRS) with hazard ratios [HR] for the highest as compared with the lowest quartile for IL-6 of 1.95 (95%CI: 1.38-2.75, p for trend<0.001), TNF-a of 1.45 (95%CI: 1.04-2.02, p for trend 0.03), of 1.66 (95%CI: 1.19-2.31) for AAI £0.9, as compared to AAI 1.01-1.30. CRP and aPWV were not independently associated with CHD events. Results were similar for "hard" CHD events. Addition of IL-6 and AAI to traditional cardiovascular risk factors yielded the greatest improvement in the prediction of CHD; C-index for "hard"/total CHD events increased from 0.62/0.62 for traditional risk factors to 0.64/0.64 for IL-6 addition, 0.65/0.63 for AAI, and 0.66/0.64 for IL-6 combined with AAI. Being in the highest quartile of IL-6 combined with an AAI £ 0.90 or >1.40 yielded an HR of 2.51 (1.50-4.19) and 4.55 (1.65-12.50) above FRS, respectively. With use of CHD risk categories, risk prediction at 5 years was more accurate in models that included IL-6, AAI or both, with 8.0, 8.3 and 12.1% correctly reclassified respectively. CONCLUSIONS: Among older adults, markers of atherosclerosis and of inflammation, particularly IL-6 and AAI, are independently associated with CHD. However, these markers only modestly improve cardiovascular risk prediction beyond traditional risk factors.

Activity assessment of eosinophilic esophagitis.

The activity of eosinophilic esophagitis (EoE) can be assessed with patient-reported outcomes and biologic measures. Patient-reported outcomes include symptoms and quality of life, whereas biologic measures refer to endoscopic, histologic, and biochemical activity (e.g. blood biomarkers). So far, a validated tool to assess EoE activity in the above-mentioned dimensions is lacking. Given the lack of a standardized way to assess EoE activity in the various dimensions, the results of different clinical trials may be difficult to compare. For symptom assessment in adult patients, the symptom 'dysphagia' should be evaluated according to different standardized food consistencies. Furthermore, symptom assessment should take into account the following items: avoidance of specific food categories, food modification, and time to eat a regular meal. A distinct symptom recall period (e.g. 2 weeks) has to be defined for symptom assessment. Performing an 'esophageal stress test' with ingestion of a standardized meal to measure symptom severity bears the potential risk of acute food bolus impaction and should therefore be avoided. The description of endoscopic findings in EoE has meanwhile been standardized. Histologic evaluation of EoE activity should report either the size of the high-power field used or count the eosinophils per mm(2). There is a current lack of blood biomarkers demonstrating a good correlation with histologic activity in esophageal biopsies. The development and validation of an adult and pediatric EoE activity index is urgently needed not only for clinical trials and observational studies, but also for daily practice.

Appropriate therapy for fistulizing and fibrostenotic Crohn's disease: results of a multidisciplinary international expert panel (EPACT II)

Introduction Many therapeutic decisions in the management of fistulizing and fibrostenotic Crohn's disease (CD) have to be taken without the benefit of strong scientific evidence. For this reason, explicit appropriateness criteria for CD fistula and stenosis treatment were developed by a multidisciplinary European expert panel in 2004 with the aim of making them easily available on the Internet and thus allowing individual case scenario evaluation; these criteria were updated in 2007. Methods Twelve international experts convened in Geneva, Switzerland in December 2007. Explicit clinical scenarios, corresponding to real daily practice, were rated on a 9-point scale based on evidence from the published literature and panelists' own expertise. Median ratings were stratified into three categories: appropriate (7-9), uncertain (4-6) and inappropriate (1-3). Results Overall, panelists rated 60 indications pertaining to fistulas. Antibiotics, azathioprine/6-mercaptopurine and conservative surgery are the mainstay of therapy for simple and complex fistulas. In the event of previous failure of azathioprine/6-mercaptopurine therapy, methotrexate and infliximab were considered appropriate for complex fistulas. The panel also rated 72 indications related to the management of fibrostenotic CD. The experts considered balloon dilation, if the stricture was endoscopically accessible, stricturoplasty and bowel resection to be appropriate for small bowel fibrostenotic Crohn's disease, and balloon dilation and bowel resection appropriate for fibrostenotic colonic disease. In the presence of an ileocolonic or ileorectal anastomotic stricture of <7 cm, endoscopic balloon dilation, and bowel resection were considered appropriate. Conclusion Antibiotics, azathioprine/6-mercaptopurine, and conservative surgery are the mainstay of therapy for fistulizing Crohn's disease. Infliximab is a therapeutic option in patients without prior response to immunosuppressant therapy. In fibrostenotic Crohn's disease, endoscopic balloon dilation, if feasible, or surgical therapy should be considered. These expert recommendations are available online (www.epact.ch). Prospective evaluation is now needed to test the validity of these appropriateness criteria in clinical practice.

A model for physical activity, bahaviour and energy expenditure assessment in real-life condition

RésuméL'origine de l'obésité, qui atteint des proportions épidémiques, est complexe. Elle est liée au mode de vie et au comportement des individus par rapport à l'activité physique, expression des choix individuels et de l'interaction avec l'environnement. Les mesures du comportement au niveau de l'activité physique des individus face à leur environnement, la répartition des types d'activité physique, la durée, la fréquence, l'intensité, et la dépense énergétique sont d'une grande importance. Aujourd'hui, il y a un manque de méthodes permettant une évaluation précise et objective de l'activité physique et du comportement des individus. Afin de compléter les recherches relatives à l'activité physique, à l'obésité et à certaines maladies, le premier objectif du travail de thèse était de développer un modèle pour l'identification objective des types d'activité physique dans des conditions de vie réelles et l'estimation de la dépense énergétique basée sur une combinaison de 2 accéléromètres et 1 GPS. Le modèle prend en compte qu'une activité donnée peut être accomplie de différentes façons dans la vie réelle. Les activités quotidiennes ont pu être classées en 8 catégories, de sédentaires à actives, avec une précision de 1 min. La dépense énergétique a pu peut être prédite avec précision par le modèle. Après validation du modèle, le comportement des individus de l'activité physique a été évalué dans une seconde étude. Nous avons émis l'hypothèse que, dans un environnement caractérisé par les pentes, les personnes obèses sont tentées d'éviter les pentes raides et de diminuer la vitesse de marche au cours d'une activité physique spontanée, ainsi que pendant les exercices prescrits et structurés. Nous avons donc caractérisé, par moyen du modèle développé, le comportement des individus obèses dans un environnement vallonné urbain. La façon dont on aborde un environnement valloné dans les déplacements quotidiens devrait également être considérée lors de la prescription de marche supplémentaire afin d'augmenter l'activité physique.SummaryOrigin of obesity, that reached epidemic proportion, is complex and may be linked to different lifestyle and physical activity behaviour. Measurement of physical activity behaviour of individuals towards their environment, the distribution of physical activity in terms of physical activity type, volume, duration, frequency, intensity, and energy expenditure is of great importance. Nowadays, there is a lack of methods for accurate and objective assessment of physical activity and of individuals' physical activity behaviour. In order to complement the research relating physical activity to obesity and related diseases, the first aim of the thesis work was to develop a model for objective identification of physical activity types in real-life condition and energy expenditure based on a combination of 2 accelerometers and 1 GPS device. The model takes into account that a given activity can be achieved in many different ways in real life condition. Daily activities could be classified in 8 categories, as sedentary to active physical activity, within 1 min accuracy, and physical activity patterns determined. The energy expenditure could be predicted accurately with an accuracy below 10%. Furthermore, individuals' physical activity behaviour is expression of individual choices and their interaction with the neighbourhood environment. In a second study, we hypothesized that, in an environment characterized by inclines, obese individuals are tempted to avoid steep positive slopes and to decrease walking speed during spontaneous outdoor physical activity, as well as during prescribed structured bouts of exercise. Finally, we characterized, by mean of the developed model, the physical activity behaviour of obese individuals in a hilly urban environment. Quantifying how one tackles hilly environment or avoids slope in their everyday displacements should be also considered while prescribing extra walking in free-living conditions in order to increase physical activity.

Revised definitions of invasive fungal disease from the European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC/MSG) Consensus Group.

BACKGROUND: Invasive fungal diseases are important causes of morbidity and mortality. Clarity and uniformity in defining these infections are important factors in improving the quality of clinical studies. A standard set of definitions strengthens the consistency and reproducibility of such studies. METHODS: After the introduction of the original European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC/MSG) Consensus Group definitions, advances in diagnostic technology and the recognition of areas in need of improvement led to a revision of this document. The revision process started with a meeting of participants in 2003, to decide on the process and to draft the proposal. This was followed by several rounds of consultation until a final draft was approved in 2005. This was made available for 6 months to allow public comment, and then the manuscript was prepared and approved. RESULTS: The revised definitions retain the original classifications of "proven," "probable," and "possible" invasive fungal disease, but the definition of "probable" has been expanded, whereas the scope of the category "possible" has been diminished. The category of proven invasive fungal disease can apply to any patient, regardless of whether the patient is immunocompromised, whereas the probable and possible categories are proposed for immunocompromised patients only. CONCLUSIONS: These revised definitions of invasive fungal disease are intended to advance clinical and epidemiological research and may serve as a useful model for defining other infections in high-risk patients.

From controlling to letting go : what are the psychosocial needs of parents of adolescents with a chronic illness?

While one of the main objectives of adolescence is to achieve autonomy, for the specific population of adolescents with a chronic illness (CI), the struggle for autonomy is accentuated by the limits implied by their illness. However, little is known concerning the way their parents manage and cope with their children's autonomy acquisition. Our aim was to identify the needs and preoccupations of parents of adolescents with CI in coping with their children's autonomy acquisition and to determine whether mothers and fathers coped differently. Using a qualitative approach, 30 parents of adolescents with CI participated in five focus groups. Recruitment took place in five specialized pediatric clinics from our university hospital. Thematic analysis was conducted. Transcript analyses suggested four major categories of preoccupations, those regarding autonomy acquisition, giving or taking on autonomy, shared management of treatment and child's future. Some aspects implied differences between mothers' and fathers' viewpoints and ways of experiencing this period of life. Letting go can be hard for the father, mother, adolescent or all three. Helping one or the other can in turn improve family functioning as a whole. Reported findings may help health professionals better assist parents in managing their child's acquisition of autonomy.

Changes in patterns of practice for prostate cancer radiotherapy in Italy 1995-2003. A survey of the Prostate Cancer Study Group of the Italian Radiation Oncology Society.

Aims and background. In 2002, a survey including 1759 patients treated from 1980 to 1998 established a "benchmark" Italian data source for prostate cancer radiotherapy. This report updates the previous one. Methods. Data on clinical management and outcomes of 3001 patients treated in 15 centers from 1999 through 2003 were analyzed and compared with those of the previous survey. Results. Significant differences in clinical management (-10% had abdominal ma-gnetic resonance imaging; +26% received ≥70 Gy, +48% conformal radiotherapy, -20% pelvic radiotherapy) and in G3-4 toxicity rates (-3.8%) were recorded. Actuarial 5-year overall, disease-specific, clinical relapse-free, and biochemical relapse-free survival rates were 88%, 96%, 96% and 88%, respectively. At multivariate analysis, D'Amico risk categories significantly impacted on all the outcomes; higher radiotherapy doses were significantly related with better overall survival rates, and a similar trend was evident for disease-specific and biochemical relapse-free survival; cumulative probability of 5-year late G1-4 toxicity was 24.8% and was significantly related to higher radiotherapy doses (P <0.001). Conclusions. The changing patterns of practice described seem related to an improvement in efficacy and safety of radiotherapy for prostate cancer. However, the impact of the new radiotherapy techniques should be prospectively evaluated.

Predictors of awakening from postanoxic status epilepticus after therapeutic hypothermia.

BACKGROUND: Postanoxic status epilepticus (PSE) is considered a predictor of fatal outcome and therefore not intensively treated; however, some patients have had favorable outcomes. The aim of this study was to identify favorable predictors for awakening beyond vegetative state in PSE. METHODS: We studied six subjects treated with hypothermia improving beyond vegetative state after cerebral anoxia, despite PSE. They were among a cohort of patients treated for anoxic encephalopathy with therapeutic hypothermia in our institution between October 1999 and May 2006 (retrospectively, 3/107 patients) and June 2006 and May 2008 (prospectively, 3/74 patients). PSE was defined by clinical and EEG criteria. Outcome was assessed according to the Glasgow-Pittsburgh Cerebral Performance Categories (CPC). RESULTS: All improving patients had preserved brainstem reflexes, cortical somatosensory evoked potentials, and reactive EEG background during PSE. Half of them had myoclonic PSE, while three had nonconvulsive PSE. In the prospective arm, 3/28 patients with PSE showed this clinical-electrophysiologic profile; all awoke. Treatments consisted of benzodiazepines, various antiepileptic drugs, and propofol. One subject died of pneumonia in a minimally conscious state, one patient returned to baseline (CPC1), three had moderate impairment (CPC2), and one remained dependent (CPC3). Patients with nonconvulsive PSE showed a better prognosis than subjects with myoclonic PSE (p = 0.042). CONCLUSION: Patients with postanoxic status epilepticus and preserved brainstem reactions, somatosensory evoked potentials, and EEG reactivity may have a favorable outcome if their condition is treated as status epilepticus.

First-line therapies in inflammatory bowel disease.

Background and Aims: Medical therapy of inflammatory bowel disease (IBD) is becoming more complex, given the increasing choice of drugs to treat Crohn's disease (CD) and ulcerative colitis (UC). We aimed to summarize the current guidelines for first-line treatments in IBD. Methods: An extensive literature search with focus on the guidelines of the European Crohn's and Colitis Organisation for the diagnosis and treatment of CD and UC was performed. First-line treatments were defined as the following drug categories: 5-aminosalicylates, budesonide, systemic steroids, azathioprine, 6-mercaptopurine, methotrexate, infliximab, adalimumab and certolizumab pegol. The following drug categories were not included: cyclosporine and tacrolimus (not yet approved by Swissmedic for IBD treatment). Results: Treatment recommendations for the following clinically frequent situations are presented according to disease severity: ileocecal CD, colonic CD, proximal small bowel CD and perianal CD. For UC the following situations are presented: ulcerative proctitis, left-sided colitis and pancolitis. Conclusions: We provide a summary on the use of first-line therapies for clinically frequent situations in patients with CD and UC.

Object and Scene Classification: what does a Supervised Approach Provide us?

Given a set of images of scenes containing different object categories (e.g. grass, roads) our objective is to discover these objects in each image, and to use this object occurrences to perform a scene classification (e.g. beach scene, mountain scene). We achieve this by using a supervised learning algorithm able to learn with few images to facilitate the user task. We use a probabilistic model to recognise the objects and further we classify the scene based on their object occurrences. Experimental results are shown and evaluated to prove the validity of our proposal. Object recognition performance is compared to the approaches of He et al. (2004) and Marti et al. (2001) using their own datasets. Furthermore an unsupervised method is implemented in order to evaluate the advantages and disadvantages of our supervised classification approach versus an unsupervised one

'Se dire similaire et différent': la (re)présentation de soi et la négociation discursive des références identitaires des ressortissants ex-yougoslaves musulmans au Luxembourg

Cette thèse, qui se base sur des entretiens qualitatifs, porte sur la négociation des références identitaires de musulmans immigrés et réfugiés en provenance de Γ ex-Yougoslavie au Luxembourg et s'intéresse à la pertinence changeante de la religion dans la conception de soi. Selon une approche constructiviste et interactionniste, l'identité est conçue comme un projet constamment négocié, reconstruit dans des processus d'interaction sociale et en fonction des contextes sociaux. Nos données suggèrent l'émergence de constructions identitaires complexes et attestent de la pluridimensionalité et de l'intersectionnalité des références identitaires utilisées dans la conception de soi et témoignent de la non-réduction des individus à des catégories fixes. Différentes catégories sont rendues significatives et de multiples frontières sont établies afin de se différencier de figures d'altérité changeantes, sélectivement choisies pour construire une certaine image de soi. Les discours identitaires témoignent de l'aspiration à une identité positive, dans une situation caractérisée par la perte du statut social et des stigmatisations multiples, en tant que ex-Yougoslaves, demandeurs d'asile et musulmans. Nos interlocuteurs établissent un répertoire identitaire composé de marqueurs transposés, inventés et revalorisés, leur permettant de reconstruire une identité positive pour soi et leurs audiences. Ce travail décrit les manières dont les individus établissent leur répertoire identitaire à l'aide de marqueurs transposés, inventés et revalorisés, leur permettant de reconstruire une identité positive pour soi et leurs audiences et montre comment les processus de différenciation de 'l'autre' dans le pays d'origine et d'accueil sont reliés. - The question addressed in this project with a qualitative design, is how muslim migrants and refugees from the former Socialist Federal Republic of Yugoslavia in Luxemburg negotiate salient identity references in a new social political environment and discusses the changing significance of religion and the way it is integrated in the identity patchwork. According to a constructivist and interactionist approach, conceiving identity as a constantly negotiated project, reconstructed in interaction and with regard to social context, identities are relevant only in relation to particular other groups and in certain situations of interaction. Our data suggest the emergence of complex identity patterns using multiple references for self- description and attest of the intersectionnality of identity references and show that individuals can't be reduced to fixed categories. Different categories are made salient and multiple symbolic boundaries are established in order to differentiate from different "others", selected in order to construct a certain self-concept. The discourses of our participants attest of an aspiration towards a positive identity in a situation characterized by the loss of social status and multiple stigmata. This thesis describes the ways how individuals establish their identity repertoire with invented, transposed and negotiated identity references, that allow them to construct a favourable identity for themselves and their public and shows how différenciation processes in home and host country are related.

A comprehensive analysis of gene expression profiles in distal parts of the mouse renal tubule.

The distal parts of the renal tubule play a critical role in maintaining homeostasis of extracellular fluids. In this review, we present an in-depth analysis of microarray-based gene expression profiles available for microdissected mouse distal nephron segments, i.e., the distal convoluted tubule (DCT) and the connecting tubule (CNT), and for the cortical portion of the collecting duct (CCD; Zuber et al., Proc Natl Acad Sci USA 106:16523-16528, 2009). Classification of expressed transcripts in 14 major functional gene categories demonstrated that all principal proteins involved in maintaining the salt and water balance are represented by highly abundant transcripts. However, a significant number of transcripts belonging, for instance, to categories of G-protein-coupled receptors or serine/threonine kinases exhibit high expression levels but remain unassigned to a specific renal function. We also established a list of genes differentially expressed between the DCT/CNT and the CCD. This list is enriched by genes related to segment-specific transport functions and by transcription factors directing the development of the distal nephron or collecting ducts. Collectively, this in silico analysis provides comprehensive information about relative abundance and tissue specificity of the DCT/CNT and the CCD expressed transcripts and identifies new candidate genes for renal homeostasis.

Categorization of bibsonomy tags to apply privacy-preserving mechanisms.

In this technical report, we approach one of the practical aspects when it comes to represent users' interests from their tagging activity, namely the categorization of tags into high-level categories of interest. The reason is that the representation of user profiles on the basis of the myriad of tags available on the Web is certainly unfeasible from various practical perspectives; mainly concerningthe unavailability of data to reliably, accurately measure interests across such fine-grained categorization, and, should the data be available, its overwhelming computational intractability. Motivated by this, our study presents the results of a categorization process whereby a collection of tags posted at BibSonomy #http://www.bibsonomy.org# are classified into 5 categories of interest. The methodology used to conduct such categorization is in line with other works in the field.
