A importância da geometria dos implantes para o planejamento em reabilitação oral: revisão de literatura

The design of implant structure is still a questioning to the professionals, while their variations can to influence of stress distribution favorably to bone. Therefore, the aim of study was to review addressing the topic of osseointegrated implants design establishing answers for the patient oral rehabilitation, according variations existing on the market. It was conducted a detailed search strategy by the PubMed/ Medline and Bireme, it was used as descriptors: “dental implants cylinder”; “dental implants thread”; “dental implants geometry”, until May 2014. From 798 articles, after review were selected 18 articles and 1 specific area book. The results were divided to compare design of implant and threads for further discussion and conclusions. Thus, conclude that the threads implants are best used because of its advantages with respect to the stress distribution and stability primary. The variations of the differents types of threads, have influence for stress distribution.

Detecção de microrganismos de infecções bucais: perspectivas e cuidados a serem seguidos

The diagnosis of head and neck infections constitutes relevant step in their treatment. However, in spite of the fact that most of diseases in head and neck region are infectious in nature, several reasons collaborated for dentists do not ask laboratory tests in order to help clinical diagnosis. By mean of this review literature, based on research articles about the newest and most reliable methods of diagnosis for clinical laboratories, the authors discuss the advantages and disadvantages of each selected method and the relevant aspects in transportation of the specimens to the laboratory. Saliva, biofilm, pus, and blood are the most frequent specimens for microbial diagnosis, being that the most used methods are culture and those based on detection of deoxyribonucleic acid by polymerase chain reaction method. Whereas, the culture depends on cellular viability, and has reduced sensitivity, as well as needs favorable conditions in the sample collection and transportation, PCR shows high sensitivity and specificity, but it does not allow the determination of antibiogram, what reduces its usefulness. In addition, few laboratories possess conditions to perform cultivation of obligate anaerobes or have experience in the molecular detection of these microorganisms.

Mortalidade Materna: uma abordagem atualizada

Purpose: to review literature, highlighting current aspects of maternal mortality.  Method: research initiated through electronic data base PubMed [http:// www.ncbi.nlm.nih.gov/pubmed], limited to the last 10 years. The selected cases which related to pre-defined aspects of interest to the study, such as vulnerable population, risk factors, causes, difficulties in obtaining data, preventive measures e new approaches to the problem, among them, ‘near misses’ and severe maternal morbidity.  Results: maternal death is directly related to the quality of life of the population, with relevant disparities among the different social economic areas. Although maternal mortality is the proper indicator to the female population health, its numbers are presented in unrealistic manners due to the difficulties in identifying the cases through death certificates. Preventive measures associated to early and adequate diagnose and treatment are benefic factors in decreasing those maternal deaths. Apart from these, identification and classification of ‘near misses’ and maternal morbidity are featured in the contemporary approach to the issue.  Final considerations: In spite of advanced technology and recognition of preventive measures, a large number of women die daily due to complications in the pregnancy and puerperal cycle. To decrease such tragedy political, social and economical commitment to Health is necessary, in order to promote the needed reforms in the assistance of such cycle.

Treatment of adolescents with early-onset schizophrenia spectrum disorders: in search of a rational, evidence-informed approach

Purpose of review: We aimed to review literature on the efficacy and tolerability of psychosocial and psychopharmacological interventions in youth with early-onset schizophrenia spectrum disorders (EOS). A rationale for pragmatic psychopharmacology in EOS, including dosing, switching and adverse effect monitoring and management, is provided. Recent findings: Three randomized controlled trials (RCTs) over the last 8 years demonstrated benefits of psychosocial interventions (i.e. psychoeducation, cognitive remediation, cognitive behavioural therapy) for EOS without clear advantages of one psychosocial treatment over another. Six large, placebo-controlled, short-term RCTs over the last 4 years demonstrated that aripiprazole, olanzapine, paliperidone, quetiapine and risperidone, but not ziprasidone, were superior to placebo. Except for clozapine's superiority in treatment-refractory EOS, efficacy appeared similar across studied first-generation and second-generation antipsychotics, but tolerability varied greatly across individual agents. Summary: Antipsychotics are efficacious in the treatment of EOS. Given the lack of efficacy differences between antipsychotics (except for clozapine for treatment-refractory EOS), we propose that tolerability considerations need to guide choice of antipsychotics. Further and longer-term efficacy and effectiveness studies are urgently needed that should also explore pharmacologic and nonpharmacologic augmentation strategies.

Hybridization and Introgression Between Native and Alien Species

Human activities, such intentional and unintentional transplantations, and habitat alterations including the establishment of migration corridors, generate increasing opportunities for formerly allopatric taxa to meet and to hybridize. There is indeed increasing evidence that these introduced plant and animal taxa (including crop plants and domesticated animal taxa) frequently hybridize with native relatives and with other introduced taxa, leading to a growing concern that these hybridizations may compromise the genetic integrity of native taxa to the point of causing extinctions (Abbott 1992; Rhymer and Simberloff 1996; Levin et al. 1996; Ellstrand and Schierenbeck 2000; Vilà et al. 2000). A decade ago, Rhymer and Simberloff (1996) stated in their review on this topic that the known cases are probably just the tip of the iceberg.Using the search term ‘hybridization and introgression’, the Web of Science database yields a total of 1,178 research articles, of which 935 (or 80 %) have been published after 1995 (Fig. 16.1). Indeed, the evidence for natural and man-induced hybridization and introgression appears to have increased exponentially these last few years.

Developmental tasks as a framework to study personality development in adulthood and old age

Research consistently shows that personality development is a lifelong phenomenon, with mean-level and rank-order changes occurring in all life phases. What happens during specific life phases that can explain these developmental patterns? In the present paper, we review literature linking personality development in different phases of adulthood to developmental tasks associated with these phases. Building on previous work, we describe several categories of developmental tasks that are present in all phases of adulthood. However, the specific tasks within these categories change across adulthood from establishing new social roles in early adulthood to maintaining them in middle adulthood and preventing losses in old age. This trajectory is reflected in mean-level changes in personality, which indicates development towards greater maturity (increases in social dominance, conscientiousness, and emotional stability) in early and middle adulthood, but less so at the end of life. Importantly, developmental tasks are not only associated with mean-level changes, but the way in which people deal with these tasks is also related to rank-order changes in personality. We provide an outlook for future research on how the influence of historical time on the normativeness of developmental tasks might be reflected in personality development.

Integrating attentional control theory and the strength model of self-control

In the present article, we argue that it may be fruitful to incorporate the ideas of the strength model of self-control into the core assumptions of the well-established attentional control theory (ACT). In ACT, it is assumed that anxiety automatically leads to attention disruption and increased distractibility, which may impair subsequent cognitive or perceptual-motor performance, but only if individuals do not have the ability to counteract this attention disruption. However, ACT does not clarify which process determines whether one can volitionally regulate attention despite experiencing high levels of anxiety. In terms of the strength model of self-control, attention regulation can be viewed as a self-control act depending on the momentary availability of self-control strength. We review literature that has revealed that self-control strength moderates the anxiety-performance relationship, discuss how to integrate these two theoretical models, and offer practical recommendations of how to counteract negative anxiety effects.

Arquitectura experimental en España 1965-1985

Entre los años 1965 y 1985, arquitectos españoles irrumpieron con una serie de aportaciones singulares que abrieron nuevas líneas de exploración más allá de los límites que marcaba la tradición. Se trata de un conjunto de prácticas arquitectónicas que podríamos calificar de “experimentales”3. El carácter aislado y disperso de estas manifestaciones4, ha contribuido a su desconocimiento y falta de difusión tanto dentro como fuera de nuestras fronteras. Hasta la fecha no se ha realizado una revisión del tema en su conjunto. Con este estudio se pretende analizar la producción arquitectónica experimental de este periodo en su globalidad, generar una estructura que permita incluir las distintas vías experimentales, de idear y proyectar arquitectura, que podemos encontrar dentro de nuestro territorio, inscribiéndolas en un contexto más amplio. Se han identificado cuatro nichos de experimentación en torno a los cuales se estructura la producción experimental española en el arco temporal definido: “sistemas de organización espacial”, “interacción con el medio ambiente”, “lógica constructiva e imaginación material” y “el campo expandido del lenguaje y el proceso proyectual”. La comprensión de estas manifestaciones, con una mirada global, es la que mejor puede contribuir a la construcción de un corpus propio, que sea reconocible por sus diferencias y especificidades. Se trata igualmente de un estudio comparado, que busca facilitar la inscripción de las prácticas experimentales españolas en el marco de la cultura internacional, no como una excepción encerrada en su particularismo, ni como una derivación inmediata de tendencias externas, sino como una realidad donde apoyar una historia que entrelaza lo local y lo internacional. En definitiva, con esta investigación se pretende recuperar un fragmento reciente de la arquitectura en España, en un periodo clave, en el que comienza a abrirse al intercambio de teorías y prácticas, con el resto de Europa y América. Incluyendo voces paralelas al discurso central, que habían sido desplazadas durante el proceso de construcción del mismo, se quiere participar en la transmisión de un legado completo de nuestra cultura y práctica arquitectónica. ABSTRACT Between the years 1965 and 1985, Spanish architects burst in with unique contributions that could be described as "experimental"1. The isolated and dispersed nature of these occurrences2 has contributed to the oversight and lack of dissemination of the Spanish experimental architecture both within and beyond our borders. To date, there has been no review of the topic in its entirety. This study tries to examine the experimental architectural production of this period as a whole, generating a structure that allows for the inclusion of different experimental ways of envisioning and projecting architecture within our territory, registering them in a wider context. Four niches of experimentation have been identified around which the Spanish experimental production in the time span defined: "spatial organisation systems," "interaction with the environment", "constructive logic and equipment imagination" and” expanded field of language and the design process. " Understanding these manifestations, with a global perspective, can best contribute to the construction of our own corpus, which is recognisable by their differences and specificities. At the same time, it is a comparative study that seeks to facilitate the registration of the Spanish experimental practices within the framework of international culture, not as an exception enclosed in its particularity, not as an immediate derivation of external trends, but as a reality to support a story that weaves together the local and the international. In short, it deals with recovering a recent fragment of architecture, in a key period in which Spain begins to open to the exchange of cultural and architectural theories and practices with the rest of Europe and America. Including parallel voices to the central discourse, which until recently had been displaced during the construction processes of that same discourse, this research wants to participate in the transmission of a complete legacy of the history of our culture and architectural practice.

Developmental anomalies of the eye: the genetic link

As in other areas of the body, developmental anomalies of the eye arise as a result of the disturbance of events during embryology and in a proportion of cases these anomalies are genetically inherited. Developmental anomalies that occur early in embryonic life may be so severe that the embryo may not survive but others result in the birth of healthy babies but with developmental eye defects of varying severity. The most dramatic developmental defects of the eye include anophthalmos (complete absence of an eye), microphthalmos (a general failure of the eye to develop resulting in a small, undeveloped eye), coloboma (caused by failure of the optic vesicle to invaginate), and aniridia (complete or partial loss of the iris). The present article does not provide an exhaustive review of the topic but considers the major types of developmental anomaly to affect the eye and will discuss how recent progress in genetics has increased our understanding of these disorders. The major genes linked to the developmental anomalies are discussed as well as how defects in these genes might lead to specific problems.

Importance and Benefits of OPEN SCIENCE for Ubiquitous Sharing, Dissemination and Impact

While openness is well applied to software development and exploitation (open sources), and successfully applied to new business models (open innovation), fundamental and applied research seems to lag behind. Even after decades of advocacy, in 2011 only 50% of the public-funded research was freely available and accessible (Archambault et al., 2013). The current research workflows, stemming from a pre-internet age, result in loss of opportunity not only for the researchers themselves (cf. extensive literature on topic at Open Access citation project, http://opcit.eprints.org/), but also slows down innovation and application of research results (Houghton & Swan, 2011). Recent studies continue to suggest that lack of awareness among researchers, rather than lack of e-infrastructure and methodology, is a key reason for this loss of opportunity (Graziotin 2014). The session will focus on why Open Science is ideally suited to achieving tenure-relevant researcher impact in a “Publish or Perish” reality. Open Science encapsulates tools and approaches for each step along the research cycle: from Open Notebook Science to Open Data, Open Access, all setting up researchers for capitalising on social media in order to promote and discuss, and establish unexpected collaborations. Incorporating these new approaches into a updated personal research workflow is of strategic beneficial for young researchers, and will prepare them for expected long term funder trends towards greater openness and demand for greater return on investment (ROI) for public funds.
