    Full Text Available Este trabalho consistiu em um estudo etnográfico, cujo objetivo foi compreender o significado cultural do cuidado humanizado, na perspectiva da equipe de enfermagem que atua na Unidade de Terapia Intensiva do Hospital das Clínicas da Universidade Federal de Goiás. Para a coleta de dados, foram realizadas observações participantes e entrevistas semi-estruturadas com enfermeiros, técnicos e auxiliares de enfermagem, em seu ambiente de trabalho. Com a análise dos dados, emergiram três categorias principais que deram sentido ao significado do cuidado humanizado na UTI: cuidado Humanizado - amar ao próximo como a si mesmo; cuidado humanizado - não está presente como deveria estar; estresse e sofrimento: é preciso cuidar de quem cuida. O tema cultural foi o cuidado humanizado - muito falado e pouco vivido. Esse tema mostra a realidade do cuidar em terapia intensiva, envolvendo uma equipe de enfermagem que tem um conceito de humanização sintetizado na expressão: amar ao próximo como a si mesmo, mas que, na prática, não revela esse pensamento tão profundo.

    Full Text Available

    Listeria monocytogenes é o agente infeccioso responsável pela doença de origem alimentar denominada listeriose. Apesar de baixa incidência, a listeriose representa importante risco à saúde pública, pelo grau de severidade das seqüelas e alto índice de mortalidade (20% a 30% que promove em populações de risco, como pacientes imunocomprometidos, idosos e gestantes. No Brasil e em outros países em desenvolvimento, além da falta de preocupação por parte das autoridades de saúde pública em relação à sua disseminação, não há estatísticas oficiais de casos de listeriose, pois sua notifi cação não é obrigatória. Considerando o aumento da incidência de L. monocytogenes no mundo todo, e a falta de informações atualizadas na língua portuguesa sobre o comportamento desta bactéria, sua prevalência, fatores de virulência e outros aspectos relevantes para a saúde pública, se elaborou esta revisão.

    Full Text Available Hemangiomas are the most common benign tumors of childhood. They show rapid growth, followed by a regression phase that culminates in the partial or total disappearance of the lesion. Therapeutic options should be evaluated for extensive cases. Systemic glucocorticoids are the therapy of choice; however, there are reports that propranolol offers better and faster results. We report two cases of large volume infantile hemangioma associated with functional limitation and aesthetic disfigurement, treated successfully with propranolol, a drug that comes as a therapeutic option providing satisfactory and maintained results, with few side effects.Hemangiomas são os tumores benignos mais frequentes da infância, apresentando como história natural crescimento rápido, seguido de uma fase de regressão que culmina com o desaparecimento parcial ou total da lesão.

    Mining frequent subgraphs from a collection of input graphs is an important topic in data mining research. However, if the input graphs contain sensitive information, releasing frequent subgraphs may pose considerable threats to individual's privacy. In this paper, we study the problem of frequent subgraph mining (FGM) under the rigorous differential privacy model. We introduce a novel differentially private FGM algorithm, which is referred to as DFG. In this algorithm, we first privately identify frequent subgraphs from input graphs, and then compute the noisy support of each identified frequent subgraph. In particular, to privately identify frequent subgraphs, we present a frequent subgraph identification approach which can improve the utility of frequent subgraph identifications through candidates pruning. Moreover, to compute the noisy support of each identified frequent subgraph, we devise a lattice-based noisy support derivation approach, where a series of methods has been proposed to improve the accuracy of the noisy supports. Through formal privacy analysis, we prove that our DFG algorithm satisfies ε-differential privacy. Extensive experimental results on real datasets show that the DFG algorithm can privately find frequent subgraphs with high data utility.

    Full Text Available Mining frequent patterns in large transactional databases is a highly researched area in the field of data mining. Existing frequent pattern discovering algorithms suffer from many problems regarding the high memory dependency when mining large amount of data, computational and I/O cost. Additionally, the recursive mining process to mine these structures is also too voracious in memory resources. In this paper, we describe a more efficient algorithm for mining complete frequent itemsets from transactional databases. The suggested algorithm is partially based on FP-tree hypothesis and extracts the frequent itemsets directly from the tree. Its memory requirement, which is independent from the number of processed transactions, is another benefit of the new method. We present performance comparisons for our algorithm against the Apriori algorithm and FP-growth.

RESULTADOS: Analisamos 146 pacientes, com média de idade de 44,5 anos e predomínio do sexo feminino. O principal sintoma foi dor abdominal. Tivemos ocorrência de segundo primário em 22% dos casos e na imuno-histoquímica, 92% foram positivos para CD117. A localização mais frequente foi estômago e predominou o grupo de alto risco. A cirurgia foi R0 (extenso em 70% e os principais sítios de metástases foram fígado e peritônio. A sobrevida global foi, respectivamente, em dois e cinco anos de 86% e 59%. Houve significante diferença entre a sobrevida global (p=0,29 do grupo de alto risco versus os demais. CONCLUSÃO: Os nossos pacientes apresentam-se principalmente sob forma de doença de alto risco com repercussão óbvia na sobrevida. O uso de Imatinib melhorou a sobrevida dos pacientes com doença metastática e recidivada. Devemos estudar seu uso no cenário de adjuvância e neoadjuvancia visando melhorar os índices do grupo de alto risco. A criação de centros referenciais é uma necessidade para o estudo de doenças pouco frequentes.

    Full Text Available Association rule learning is a popular and well researched technique for discovering interesting relations between variables in large databases in the area of data mining. The association rules are a part of intelligent systems. Association rules are usually required to satisfy a user-specified minimum support and a user-specified minimum confidence at the same time. Apriori and FP-Growth algorithms are very familiar algorithms for association rule mining. In this paper we are more concentrated on the Construction of efficient frequent pattern trees. Here, we present the novel frequent pattern trees and the performance issues. The proposed trees are fast and efficient trees helps to extract the frequent patterns. This paper provides the major advantages in the FP-Growth algorithm for association rule mining with using the newly proposed approach.

    2004-12-01

    The objective of this work was to determine the osmolality of beverages frequently consumed by children and adolescents due to the scarce information available in our country. The samples were grouped as follows: milks; refreshments; beverages based on fruits, vegetables, cereals, and tubers; sport drinks; energizing drinks; oral rehydrating solutions; reconstituted drinks and infusions. A vapor pressure digital osmometer was used, five samples of each beverage from different lots were analyzed. Four osmolality determinations were made on each sample and the average of such values was calculated. When the variation coefficient of the osmolality measurements of the five samples was higher than 10%, five additional samples were analyzed. As many samples as possible were used with breast milk in the time period of the study. Osmolality averages, standard deviation, and the osmolality confidence intervals (95% reliability) were calculated. The osmolality (mmol/kg) of breast milk and that of cow milk were between 273 and 389; refreshments, white, black and flavored colas, and malts ranged between 479-811; and soda and light drinks: 44-62; fresh fruit and commercial drinks (coconut, peach, apple, orange, pear, pineapple, grape, plum, tamarind): 257-1152 and light juices: 274; sports beverages: 367; energizing drinks: 740; drinks based on vegetables and cereals: 213-516; oral rehydrating solutions: 236-397; reconstituted drinks: 145; infusions: 25. Beverages with adequate osmolality levels for children were: milks, light refreshments, soda, fresh and light juices, oral rehydrating, soy, and reconstituted drinks and infusions. PMID:15602899

    Microbial induced corrosion (MIC) is not as rare as many materials scientist and corrosion practitioners do believe. It is not an exotic and scarce event, but can be found frequently in many fields of corrosion research, provided that it is looked for. The reason for the relatively few descriptions of MIC cases seems to be the fact, that the microbiological approach is not widely known and applied in the world of materials science. MIC is not so much a corrosion mechanism on its own, but it enhances the corrosion rates of the 'normal' mechanisms to such an extent, that in some cases 'incredible' fast corrosion progress can be observed. The reason is the microorganisms' function as bio-catalysts: Chemical reactions, which are very slow under normal chemical conditions can be highly accelerated by living organisms. Besides that, several microorganisms do produce very corrosive substances which in natural environments do not occur without the activity of microorganisms, e. g. sulfuric or nitric acid. We want to point out, that it can be very worthy to take microbial induced corrosion into account. MIC is not the general answer for all unsolved corrosion problems, but to think about it helps in many corrosion cases as the authors had to experience. The initial indication for the presence of MIC are markedly increased corrosion rates. In the following, some of our 'lessons' are presented as short case studies: Two of them deal with steel corrosion characterized by increased corrosion rates. The third example presents corrosion damage of aluminium structures, where from a technical point of view corrosion was not expected, least of all microbial induced corrosion. (authors)

  5. Maximal Frequent Itemset Generation Using Segmentation Apporach

    2011-09-01

    Full Text Available Finding frequent itemsets in a data source is a fundamental operation behind Association Rule Mining.Generally, many algorithms use either the bottom-up or top-down approaches for finding these frequentitemsets. When the length of frequent itemsets to be found is large, the traditional algorithms find all thefrequent itemsets from 1-length to n-length, which is a difficult process. This problem can be solved bymining only the Maximal Frequent Itemsets (MFS. Maximal Frequent Itemsets are frequent itemsets whichhave no proper frequent superset. Thus, the generation of only maximal frequent itemsets reduces thenumber of itemsets and also time needed for the generation of all frequent itemsets as each maximal itemsetof length m implies the presence of 2m-2 frequent itemsets. Furthermore, mining only maximal frequentitemset is sufficient in many data mining applications like minimal key discovery and theory extraction. Inthis paper, we suggest a novel method for finding the maximal frequent itemset from huge data sourcesusing the concept of segmentation of data source and prioritization of segments. Empirical evaluationshows that this method outperforms various other known methods.

    2010-01-01

    In general frequent itemsets are generated from large data sets by applying association rule mining algorithms like Apriori, Partition, Pincer-Search, Incremental, Border algorithm etc., which take too much computer time to compute all the frequent itemsets. By using Genetic Algorithm (GA) we can improve the scenario. The major advantage of using GA in the discovery of frequent itemsets is that they perform global search and its time complexity is less compared to other algorithms as the genetic algorithm is based on the greedy approach. The main aim of this paper is to find all the frequent itemsets from given data sets using genetic algorithm.

  11. Mining Frequent Itemsets in Correlated Uncertain Databases

    2015-01-01

    Recently, with the growing popularity of Internet of Things (IoT) and pervasive computing, a large amount of uncertain data, e.g., RFID data, sensor data, real-time video data, has been collected. As one of the most fundamental issues of uncertain data mining, uncertain frequent pattern mining has attracted much attention in database and data mining communities. Although there have been some solutions for uncertain frequent pattern mining, most of them assume that the data is independent, which is not true in most real-world scenarios. Therefore, current methods that are based on the independent assumption may generate inaccurate results for correlated uncertain data. In this paper, we focus on the problem of mining frequent itemsets over correlated uncertain data, where correlation can exist in any pair of uncertain data objects (transactions). We propose a novel probabilistic model, called Correlated Frequent Probability model (CFP model) to represent the probability distribution of support in a given correlated uncertain dataset. Based on the distribution of support derived from the CFP model, we observe that some probabilistic frequent itemsets are only frequent in several transactions with high positive correlation. In particular, the itemsets, which are global probabilistic frequent, have more significance in eliminating the influence of the existing noise and correlation in data. In order to reduce redundant frequent itemsets, we further propose a new type of patterns, called global probabilistic frequent itemsets, to identify itemsets that are always frequent in each group of transactions if the whole correlated uncertain database is divided into disjoint groups based on their correlation. To speed up the mining process, we also design a dynamic programming solution, as well as two pruning and bounding techniques. Extensive experiments on both real and synthetic datasets verify the effectiveness and efficiency of the proposed model and algorithms.

Os exames com aparelho de Doppler bidirecional e o eco-color-Doppler apresentaram, como diagnóstico presuntivo, malformação arteriovenosa, pelo turbilhonamento do fluxo e ausência de estenoses. A tumoração foi retirada por cirurgia aberta e encaminhada para exame histopatológico, com diagnóstico de glomangioma. Este relato descreve uma doença arterial pouco frequente, que causa extremo desconforto ao seu portador, mas que é solucionada pela exerese cirúrgica, sem sequelas.We report on a case of glomus tumor in the branch of the radial artery of the right thumb. The tumor had a 4-year clinical history. The patient reported the development of a 2.0-cm tumor in the interdigital region between the first and second fingers of the right hand on the short flexor muscle of thumb. The patient also complained of severe and progressive pain. Tests using bidirectional Doppler and echo-color-Doppler revealed a presumptive diagnosis of arteriovenous malformation based on the turbulence of the flow and absence of stenosis. The tumor was removed by open surgery and sent for histopathological examination, which showed a diagnosis of glomangioma. The present report describes a rare arterial disease causing extreme discomfort to the patient, which may be treated with surgical resection without sequelae.

  13. A Tabular Approach for Frequent itemset mining

    Directory of Open Access Journals (Sweden)

    G.Krishna Mohan

    2011-02-01

    Full Text Available Frequent patterns are patterns that appear in a data set frequently. For example, a set of items, such as milk and bread that appear frequently together in a transaction data set is a frequent itemset. Frequent pattern mining searches for recurring relationships in a given data set. With massive amounts of data continuously being collected and stored, many industries are becoming interested in mining such patterns from their databases. The discovery of interesting correlation relationships among huge amounts of business transaction records can help in many business decision-making processes, such as catalog design, cross-marketing, and customer shopping behavior analysis. If we think of the universe as the set of items available at the store, then each item has a Boolean variable representing the presence or absence of that item. Each basket can then be represented by a Boolean vector of values assigned to these variables. The Boolean vectors can be analyzed for buying patterns that reflect items that are frequently associated or purchased together. A set of items is referred to as an itemset. An itemset that contains k items is a k-itemset. The occurrence frequency of an itemset is the number of transactions that contain the itemset. This is also known, simply, as the frequency, support count, or count of the itemset. The set of frequent k-itemsets is commonly denoted by Lk.

    Data mining is a field which explores for exciting knowledge or information from existing substantial group of data. In particular, algorithms like Apriori aid a researcher to understand the potential knowledge, deep inside the database. However because of the huge time consumed by Apriori to find the frequent item sets and generate rules, several applications cannot use this algorithm. In this paper, the authors describe a novel method for frequent pattern mining, a variation of Apriori Algo...

  3. A COMBINTORIAL TREE BASED FREQUENT PATTERN MINING

    Full Text Available Frequent pattern mining is a process of extracting frequently occurring itemset patterns from very large data storages. These frequent patterns are used to generate association rules which define the relationship among items. The strength of the relationship can be measured using two different units namely support value and confidence level. Any relationship that satisfies minimum threshold of support value is known as frequent pattern. There are several methods and algorithms suggested to mine frequent patterns from large databases. Most of the methods can be assessed for its complexity based on the number of processing levels and number of candidate sets with subsets that are generated in each level. In this study, the combinatorial approach which generates minimal number of combinations using a tree structure and automatically filters infrequent itemsets and mine frequent patterns is suggested. It scans input database once and carries out minimized intersections to count the support value. The complexity is based on the number of transactions and the maximum length of transactions. The new approach purely depends on the size of input transaction database. The combinatorial approach does not depend on the unknown number of processing levels and there is nocandidate sets and subsets generation. The proposed method makes minimal number of combinations when compared to number of candidate sets and subsets in other methods. The method is compared with number of existing legendary methods for its performance.

  5. Performance Evaluation of Frequent Subgraph Discovery Techniques

    Directory of Open Access Journals (Sweden)

    Saif Ur Rehman

    2014-01-01

    Full Text Available Due to rapid development of the Internet technology and new scientific advances, the number of applications that model the data as graphs increases, because graphs have highly expressive power to model a complicated structure. Graph mining is a well-explored area of research which is gaining popularity in the data mining community. A graph is a general model to represent data and has been used in many domains such as cheminformatics, web information management system, computer network, and bioinformatics, to name a few. In graph mining the frequent subgraph discovery is a challenging task. Frequent subgraph mining is concerned with discovery of those subgraphs from graph dataset which have frequent or multiple instances within the given graph dataset. In the literature a large number of frequent subgraph mining algorithms have been proposed; these included FSG, AGM, gSpan, CloseGraph, SPIN, Gaston, and Mofa. The objective of this research work is to perform quantitative comparison of the above listed techniques. The performances of these techniques have been evaluated through a number of experiments based on three different state-of-the-art graph datasets. This novel work will provide base for anyone who is working to design a new frequent subgraph discovery technique.

  6. Parallel Frequent Pattern Discovery: Challenges and Methodology

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Parallel frequent pattern discovery algorithms exploit parallel and distributed computing resources to relieve the sequential bottlenecks of current frequent pattern mining (FPM) algorithms. Thus, parallel FPM algorithms achieve better scalability and performance, so they are attracting much attention in the data mining research community. This paper presents a comprehensive survey of the state-of-the-art parallel and distributed frequent pattern mining algorithms with more emphasis on pattern discovery from complex data (e.g., sequences and graphs) on various platforms. A review of typical parallel FPM algorithms uncovers the major challenges, methodologies, and research problems in the field of parallel frequent pattern discovery,such as work-load balancing, finding good data layouts, and data decomposition. This survey also indicates a dramatic shift of the research interest in the field from the simple parallel frequent itemset mining on traditional parallel and distributed platforms to parallel pattern mining of more complex data on emerging architectures, such as multi-core systems and the increasingly mature grid infrastructure.

    Full Text Available A ocronose exógena é uma dermatose, aparentemente pouco frequente, caracterizada por hiperpigmentação negro-azulada fuliginosa, localizada na região onde foi aplicado o agente causador. Pode ser causada por uso de medicamentos sistêmicos, os antimaláricos e de uso tópico, como fenol, resorcinol, benzeno, ácido pícrico e a hidroquinona - que é um composto fenólico, com propriedade despigmentante, muito utilizado em formulações dermatológicas para o tratamento de melasma e outras hiperpigmentações. A fisiopatogenia deste processo ainda não está esclarecida e as abordagens terapêuticas são insatisfatórias. Relatam-se quatro casos de pacientes do sexo feminino que, após uso de preparados contendo hidroquinona, desenvolveram hiperpigmentação acentuada na face, caracterizadas no exame dermatológico e histopatológico como ocronose. Enfatiza-se a possibilidade de casos de ocronose exógena estarem sendo diagnosticados erroneamente, como falha de tratamento de melasma, e também para os riscos do uso indiscriminado de formulações, contendo hidroquinona, muitas vezes, sem acompanhamento médico.Exogenous ochronosis is an infrequent dermatosis characterized as a dark blue hyperpigmentation localized where the causing agent was applied. It may be caused by the use of systemic medication such as antimalarials and by the use of topic substances such as phenol, resorcinol, benzene, or hydroquinone, which is a fenolic compound with depigmentation action, largely used in the treatment of melasma and other hyperpigmentation. The physiopathology of this process is not well clear up to this moment, and the therapeutic measures are not satisfactory either. Here we present four cases of female patients that developed hyperpigmentation on their faces after the use of hydroquinone containing compounds, characterized clinically and histological as ochronosi.

    Full Text Available Em vez de aproveitar o momento de expansão da projeção internacional do Brasil para se envolver em temas representativos para o conjunto dos atores do sistema internacional, parece que sua inserção caminha confusamente em direção contrária. Desde o início da presente década, o Brasil tem mantido evidente cordialidade com os governos de Cuba, da Venezuela, da Bolívia e mais recentemente com o governo do Irã. Ao se envolver em temas portadores de elevado grau de complicação das relações do país com os demais atores tomadores de decisão, a diplomacia brasileira parece sofrer de crise de identidade. Tomados isoladamente, esses casos passam uma percepção e geram críticas, o que é natural, uma vez que o novo projeto exterior brasileiro nunca foi esclarecido ou debatido de forma ampla, mas se analisados num conjunto pode-se observar o que há por trás de tal posicionamento brasileiro e que mensagem quer passar. Após todo o debate e a não formação da Área de Livre Comércio das Américas – ALCA, iniciativa lançada pelos EUA em 1994, o governo norte-americano, mesmo atuando em diversas frentes de combate ao terror, procurou fortalecer sua presença no subcontinente sul-americano. Os EUA começaram a costurar rede de acordos bilaterais de livre comércio com países da América Central e do Sul, viabilizou sua presença militar na região andino-amazônica por meio do Plano Colômbia, procurou cooperação para instalação de bases militares no Paraguai, o que os deixariam próximos à maior represa do mundo e à gigantesca hidrelétrica de Itaipu, reinstalaram a IV Frota, facilitando o monitoramento das reservas de hidrocarbonetos no litoral brasileiro e se apressaram em apoiar a convocação de eleições em Honduras após a destituição do presidente eleito.

  9. Text Classification Using Sentential Frequent Itemsets

    Shi-Zhu Liu; He-Ping Hu

    2007-01-01

    Text classification techniques mostly rely on single term analysis of the document data set, while more concepts,especially the specific ones, are usually conveyed by set of terms. To achieve more accurate text classifier, more informative feature including frequent co-occurring words in the same sentence and their weights are particularly important in such scenarios. In this paper, we propose a novel approach using sentential frequent itemset, a concept comes from association rule mining, for text classification, which views a sentence rather than a document as a transaction, and uses a variable precision rough set based method to evaluate each sentential frequent itemset's contribution to the classification. Experiments over the Reuters and newsgroup corpus are carried out, which validate the practicability of the proposed system.

    1999-01-01

    This paper investigates the effect of uncertainty on a single firm's pricing behaviour in a dynamic menu cost model that results in (S,s)-rules where the price is fixed inside a band. It will be demonstrated that even though the band of inaction widens in response to increased uncertainty, the...... price may be changed more frequent in the short run, and in the long run it definitely will. Hence, observing frequent price changes is not necessarily inconsistent with a firm operating under menu costs. This paper relies on an article by Dixit (1991), (Review of Economic studies, 58, 141-151), but it...

    Full Text Available O diagnóstico de megalencefalia deve ser feito em vida, especialmente pela possibilidade de confusão com hidrocefalia. Os dados anamnésticos e clínicos poderão, em alguns casos, sugerir esta hipótese diagnóstica; entretanto, são as punções ventriculares que, geralmente, orientam para o diagnóstico certo. As pneumografias confirmam o diagnóstico, podendo ser dispensadas nos casos típicos. Outros exames (radiografias do crânio, eletrencefalograma ou arteriografia cerebral têm pouco valor. São apresentados 7 casos em que o diagnóstico foi feito em vida. Em um paciente havia também macroglossia e, em dois irmãos, mancha vinhosa ao nível da glabela. A incidência familiar foi observada em dois pares de crianças, sendo que em um dêles os pais eram consangüíneos. A casuística apresentada - relativa a um período de 7 anos - maior do que as encontradas na literatura compulsada, mostra que a megalencefalia não é tão rara como geralmente é admitido.

    We consider differentially private frequent itemset mining. We begin by exploring the theoretical difficulty of simultaneously providing good utility and good privacy in this task. While our analysis proves that in general this is very difficult, it leaves a glimmer of hope in that our proof of difficulty relies on the existence of long transactions (that is, transactions containing many items). Accordingly, we investigate an approach that begins by truncating long transactions, trading off errors introduced by the truncation with those introduced by the noise added to guarantee privacy. Experimental results over standard benchmark databases show that truncating is indeed effective. Our algorithm solves the "classical" frequent itemset mining problem, in which the goal is to find all itemsets whose support exceeds a threshold. Related work has proposed differentially private algorithms for the top-k itemset mining problem ("find the k most frequent itemsets".) An experimental comparison with those algorithms show that our algorithm achieves better F-score unless k is small. PMID:24039383

  9. A New Algorithm for Mining Frequent Pattern

    2002-01-01

    Mining frequent pattern in transaction database, time-series databases, and many other kinds of databases have been studied popularly in data mining research. Most of the previous studies adopt Apriori-like candidate set generation-and-test approach. However, candidate set generation is very costly. Han J. proposed a novel algorithm FP-growth that could generate frequent pattern without candidate set. Based on the analysis of the algorithm FP-growth, this paper proposes a concept of equivalent FP-tree and proposes an improved algorithm, denoted as FP-growth*, which is much faster in speed, and easy to realize. FP-growth* adopts a modified structure of FP-tree and header table, and only generates a header table in each recursive operation and projects the tree to the original FP-tree. The two algorithms get the same frequent pattern set in the same transaction database, but the performance study on computer shows that the speed of the improved algorithm, FP-growth*, is at least two times as fast as that of FP-growth.

    Carlo Caso (1940 - 2007) Our friend and colleague Carlo Caso passed away on July 7th, after several months of courageous fight against cancer. Carlo spent most of his scientific career at CERN, taking an active part in the experimental programme of the laboratory. His long and fruitful involvement in particle physics started in the sixties, in the Genoa group led by G. Tomasini. He then made several experiments using the CERN liquid hydrogen bubble chambers -first the 2000HBC and later BEBC- to study various facets of the production and decay of meson and baryon resonances. He later made his own group and joined the NA27 Collaboration to exploit the EHS Spectrometer with a rapid cycling bubble chamber as vertex detector. Amongst their many achievements, they were the first to measure, with excellent precision, the lifetime of the charmed D mesons. At the start of the LEP era, Carlo and his group moved to the DELPHI experiment, participating in the construction and running of the HPC electromagnetic c...

  12. Frequent video game players resist perceptual interference.

    Directory of Open Access Journals (Sweden)

    Aaron V Berard

    Full Text Available Playing certain types of video games for a long time can improve a wide range of mental processes, from visual acuity to cognitive control. Frequent gamers have also displayed generalized improvements in perceptual learning. In the Texture Discrimination Task (TDT, a widely used perceptual learning paradigm, participants report the orientation of a target embedded in a field of lines and demonstrate robust over-night improvement. However, changing the orientation of the background lines midway through TDT training interferes with overnight improvements in overall performance on TDT. Interestingly, prior research has suggested that this effect will not occur if a one-hour break is allowed in between the changes. These results have suggested that after training is over, it may take some time for learning to become stabilized and resilient against interference. Here, we tested whether frequent gamers have faster stabilization of perceptual learning compared to non-gamers and examined the effect of daily video game playing on interference of training of TDT with one background orientation on perceptual learning of TDT with a different background orientation. As a result, we found that non-gamers showed overnight performance improvement only on one background orientation, replicating previous results with the interference in TDT. In contrast, frequent gamers demonstrated overnight improvements in performance with both background orientations, suggesting that they are better able to overcome interference in perceptual learning. This resistance to interference suggests that video game playing not only enhances the amplitude and speed of perceptual learning but also leads to faster and/or more robust stabilization of perceptual learning.

    Full Text Available OBJETIVO: A histerectomia é uma operação muito realizada, entretanto há poucos trabalhos na literatura nacional sobre suas indicações, técnica e complicações. O objetivo deste trabalho é avaliar estes procedimentos realizados na Disciplina de Ginecologia e Obstetrícia da Faculdade de Medicina do Triângulo Mineiro. MÉTODO: Estudo retrospectivo de 470 histerectomias abdominais e 84 vaginais foi conduzido analisando as indicações, tempo de cirurgia e internação, tipo de incisão e morbidez. RESULTADOS: As principais indicações foram o mioma uterino e o prolapso uterino para as histerectomias abdominais e vaginais, respectivamente. As complicações intra-operatórias aconteceram em 3,4% e as pós-operatórias em 2,4% do total de casos. Nenhuma diferença estatística foi encontrada no número de complicações em relação ao tipo de incisão (vertical ou transversal. O tempo de cirurgia e o de hospitalização foram estatisticamente maiores nas incisões verticais. A hemorragia foi a mais freqüente complicação intra-operatória e a infecção da incisão operatória foi a mais freqüente no pós-operatório. CONCLUSÕES: A histerectomia é um procedimento de baixo risco, no entanto, a realização de revisões sobre indicações e complicações, e a pesquisa de melhores técnicas cirúrgicas são necessárias para torná-la cada vez mais segura.OBJECTIVE: Hysterectomy is a frequently performed surgery, but national literature gives limited information regarding indications, technique and complications. The aim of this study is to evaluate our results with this operation performed by the Discipline of Gynecology and Obstetrics of the Faculty of Medicine of "Triângulo Mineiro". METHODS: A retrospective study of 470 abdominal and 84 vaginal hysterectomies was conducted in which the indications, operation time, abdominal approach, hospitalization time, and morbidity were analyzed. RESULTS: Uterine myoma and uterine prolapse

  15. Frequent MAGE mutations in human melanoma.

    Otavia L Caballero

    Full Text Available BACKGROUND: Cancer/testis (CT genes are expressed only in the germ line and certain tumors and are most frequently located on the X-chromosome (the CT-X genes. Amongst the best studied CT-X genes are those encoding several MAGE protein families. The function of MAGE proteins is not well understood, but several have been shown to potentially influence the tumorigenic phenotype. METHODOLOGY/PRINCIPAL FINDINGS: We undertook a mutational analysis of coding regions of four CT-X MAGE genes, MAGEA1, MAGEA4, MAGEC1, MAGEC2 and the ubiquitously expressed MAGEE1 in human melanoma samples. We first examined cell lines established from tumors and matching blood samples from 27 melanoma patients. We found that melanoma cell lines from 37% of patients contained at least one mutated MAGE gene. The frequency of mutations in the coding regions of individual MAGE genes varied from 3.7% for MAGEA1 and MAGEA4 to 14.8% for MAGEC2. We also examined 111 fresh melanoma samples collected from 86 patients. In this case, samples from 32% of the patients exhibited mutations in one or more MAGE genes with the frequency of mutations in individual MAGE genes ranging from 6% in MAGEA1 to 16% in MAGEC1. SIGNIFICANCE: These results demonstrate for the first time that the MAGE gene family is frequently mutated in melanoma.

  17. Screening mammography interpretation test: more frequent mistakes

    International Nuclear Information System (INIS)

    Purpose: To present the mammographic cases most commonly misinterpreted by the participants in the mammography self-test proposed by the Italian Society of Medical Radiology (SIRM) National Congress in Rimini, Italy, 2002, by analysing the findings responsible for errors, suggesting reasons for the errors, and assessing possible inadequacies in the format of the test. Materials and methods: The self-test was performed on the mammograms of 160 cases (32 positive and 128 negative for cancer as confirmed by histology). The mammograms had been taken in the four standard projections and placed on four multi-panel diaphanoscopes, each displaying a set of 40 cases comprising benign and malignant cases in equal proportions. The participants were given pre-printed forms on which to note down their diagnostic judgement. We evaluated a total of 134 fully-completed forms. Among these, we identified the 23 cases most frequently misread by over 15 participants in percentages varying between 40-90%. Of these cases, 10 were malignancies and 13 were negative mammograms. On review, we also assessed the diagnostic contribution of complementary investigations (not available the participants). The 134 fully-completed forms (all of the 40 cases) yielded a total of 5360 responses, 1180 of which (22.01%) were incorrect. Of these 823 out of the 4288 cases expected to be negative (19.2%) were false positive, and 357 out of the 1072 cases expected to be positive (33.3%) were false negative. As regards the 23 most frequently misread cases, these were 10/32 (31.25%) mammograms positive for malignancy and 13/128 (10.15%) negative mammograms or mammograms showing benign disease. The 10 malignancies included 7 infiltrating ductal carcinomas, 1 infiltrating cribriform carcinoma, 1 infiltrating tubular carcinoma, and 1 carcinoma in situ. The 13 cases of benign disease - as established by histology or long-term follow-up - mistaken for malignancies by the test participants were fibrocystic breast

  18. LGM: Mining Frequent Subgraphs from Linear Graphs

    2011-01-01

    A linear graph is a graph whose vertices are totally ordered. Biological and linguistic sequences with interactions among symbols are naturally represented as linear graphs. Examples include protein contact maps, RNA secondary structures and predicate-argument structures. Our algorithm, linear graph miner (LGM), leverages the vertex order for efficient enumeration of frequent subgraphs. Based on the reverse search principle, the pattern space is systematically traversed without expensive duplication checking. Disconnected subgraph patterns are particularly important in linear graphs due to their sequential nature. Unlike conventional graph mining algorithms detecting connected patterns only, LGM can detect disconnected patterns as well. The utility and efficiency of LGM are demonstrated in experiments on protein contact maps.

    Full Text Available It is possible to conduct an analysis of the incidence of viral diseases in calves if these diseases are divided into two basic groups. One group comprises diseases of respiratory organs which are manifested by symptoms of a respiratory syndrome, and the second group comprises diseases of digestive tract organs in the form of a gastrointestinal syndrome. It is considered that viruses have the dominant role in the complex etiology of the respiratory syndrome, primarily the IBR virus or the Bovine Herpes Virus-1 (BHV-1, followed by the parainfluenza 3 virus (RSV, the Bovine Viral Diahrrea Virus (BVDV, the bovine Respiratory Syncytial Virus (RSV, but also other viruses, such as adenoviruses, rhinoviruses, coronaviruses, can also influence the appearance of the respiratory syndrome. The respiratory syndrome is rarely caused by a single viral agent, but most frequently by mixed viruses, but also by bacterial infections. Mixed viral infections often have a lethal outcome. Investigations of the etiology of the gastrointestinal syndrome so far indicate that, in addition to bacteria, viruses can also be a significant etiological factor. Rotaviruses, coronaviruses, adenoviruses parvoviruses, herpesviruses (the IBR virus, pestiviruses (BVDV, can be the causes of a gastrointestinal syndrome. It is believed that viruses can be the cause in about 10% cases in the ethiopathogenesis of this syndrome. The paper describes the etiopathogenesis of calf diseases of viral etiology which are most often found in the local conditions of industrial breeding of calves.

    2013-01-01

    Full Text Available Dementia in children or young adults is most frequently caused by neuronal ceroidlipofuscinoses (NCL, a group of incurable lysosomal storage disorders linked by the accumulation of a characteristic intracellular storage material and progressive clinical deterioration, usually in combination with visual loss, epilepsy, and motor decline. The clinical characteristics can vary and the age at disease onset ranges from birth to over 30 years. Diagnosis of an NCL is difficult because of genetic heterogeneity with14 NCL forms (CLN1- CLN14 identified and a high phenotype variability. A new classification of the disorders is based on the affected gene and the age at disease onset and allows a precise and practicable delineation of every NCL disease. We present a clear diagnostic algorithm to identify each NCL form. A precise diagnosis is essential for genetic counseling of affected families and for optimizing palliative care. As patient management profits from recognizing characteristic complications, care supported by a specialized team of NCL clinicians is recommended. The development of curative therapies remains difficult as the underlying pathophysiological mechanism remains unclear for all NCL forms.

    Full Text Available VANET technology integrates wireless cellular and ad hoc for seamless connectivity between vehicles. Vehicle ad-hoc networks (VANETs are systems that allow vehicles to communicate with each other. Wireless-vice can send information to nearby vehicles, and messages can be sent from one vehicle to another, so that the informationcan be spread throughout the city. In the network, there is a link failure very common due to the high mobility of nodes in the network region available. So what makes frequent link failure that packets do not reach the respective destinations. The mechanism proposed here establishes a kind of route discovery packet parallel to the real time application to be delivered to the destination, while minimizing losses. The main objective is to establish parallel paths during link failures scenarios for real-time applications to provide data to their destination safely. Recovery road parallel fixed temporary parallel path between nodes when link failure. The node beforethe link failure packet buffers, after setting the new parallel paths before the packets stored in the buffer via the destination newly created path.

Our intention is to give a simple introduction to the physics of gases that would be helpful for newcomers to the field of hypoxia research. We will provide background knowledge about questions often asked, but without straightforward answers. What is O2 concentration, and what is O2 partial pressure? What is normoxia, and what is hypoxia? How much O2 is experienced by a cell residing in a culture dish in vitro vs in a tissue in vivo? By the way, the O2 concentration in a normoxic incubator is 18.6%, rather than 20.9% or 20%, as commonly stated in research publications. And this is strictly only valid for incubators at sea level.

A tomografia computadorizada de crânio foi normal. Esse caso mostra que o reconhecimento dessa entidade clínico-eletrencefalográfica é essencial, devido à semelhança com distúrbio psiquiátrico e da pronta resposta ao tratamento medicamentoso.There are few descriptions about middle-aged patients who have nonconvulsive status epilepticus, absence status. We reported the clinical case of a woman, 52-year-old, diabetic, referred to the emergency room in a confusional state. Initial electroencephalogram showed continuous typical, bilateral, symmetric and synchronous spike-and-wave discharges. Clinical and electroencephalogram normalization occurred immediatelly following intravenous injection of benzodiazepine. Computerized axial tomography was normal. The recognition of this entity is essential because of its similarity to psychiatric disturbance and its prompt response to proper treatment.

  12. Frequently asked questions: iodinated contrast agents.

    Bettmann, Michael A

    2004-10-01

    Although iodinated contrast agents are safe and widely used, adverse events occur and questions remain about their use, safety, and interactions. Some questions are easily answered and others still require extensive investigation. For one frequent question--is informed consent necessary before all contrast media injections--the simple answer is no. Another question concerns use of contrast media in patients with prior reactions or allergies. Contrast agents can be safely used in such patients, but special care must be taken to be aware of what the previous reaction was and to be ready to treat any reaction. The protective role of pre-treatment with steroids is well established for minor reactions, but they may not prevent major reactions. It is important to realize that even life-threatening, anaphylactoid reactions are not the result of a true allergy to contrast media. Many questions arise about contrast agent-induced nephropathy. Baseline serum creatinine values should be obtained in patients who are at risk, not all patients. The incidence and natural history of contrast agent-induced nephropathy remain unclear. It occurs only in patients with compromised renal function before contrast agent injection, but even patients with normal serum creatinine levels can have renal dysfunction. Calculated creatinine clearance is a better way to determine risk and to follow this complication. The outcome in almost all patients is benign, with progression to end-stage renal disease being rare. The major risk factors, in addition to renal dysfunction, are long-standing diabetes mellitus, dehydration, and use of other nephrotoxic medications. Recent work in preventing and ameliorating contrast agent-induced nephropathy with N-acetyl cysteine, substitution of an isosmolal nonionic contrast agent, and various hydration regimens has been promising. Another common concern is use of iodinated contrast agents in pregnant or breast-feeding women. In both cases, there is no evidence

    Full Text Available A gestação heterotópica, caracterizada pela presença de gestação tópica associada à ectópica, era até pouco tempo um evento raro, ocorrendo em 1:30.000 gestações. Com o advento das técnicas de reprodução assistida, essa incidência aumentou para 1:100-500 gestações. O seu diagnóstico precoce é difícil, sendo freqüentemente realizado quando já ocorreu a ruptura da tuba uterina. Apresentamos um caso de gestação heterotópica, diagnosticado frente ao quadro de abdome agudo hemorrágico, mas com boa evolução da gravidez tópica, resultando em nascimento de feto a termo. Aponta-se a importância de se lembrar esta complicação na avaliação de mulheres submetidas a fertilização in vitro, visando ao tratamento precoce.Heterotopic gestation, characterized by the presence of combined topic and ectopic gestation, until recently was considered to be a rare event occurring in 1:30,000 pregnancies. With the appearance of assisted reproduction techniques, this incidence increased to 1:100-500 gestations. Early diagnosis is difficult and frequently is made when the uterine tube has already ruptured. It's presented a case of heterotopic pregnancy diagnosed by means of a clinical presentation of hemorrhagic acute abdomen, with good progression of the topic gestation that resulted in birth. It's pointed out the importance of considering this pathology in the evaluation of women submitted to in vitro fertilization, with the objective of early treatment.

    Complex Adaptive Systems of Systems, or CASoS, are vastly complex ecological, sociological, economic and/or technical systems which we must understand to design a secure future for the nation and the world. Perturbations/disruptions in CASoS have the potential for far-reaching effects due to pervasive interdependencies and attendant vulnerabilities to cascades in associated systems. Phoenix was initiated to address this high-impact problem space as engineers. Our overarching goals are maximizing security, maximizing health, and minimizing risk. We design interventions, or problem solutions, that influence CASoS to achieve specific aspirations. Through application to real-world problems, Phoenix is evolving the principles and discipline of CASoS Engineering while growing a community of practice and the CASoS engineers to populate it. Both grounded in reality and working to extend our understanding and control of that reality, Phoenix is at the same time a solution within a CASoS and a CASoS itself.

    Complex Adaptive Systems of Systems, or CASoS, are vastly complex eco-socio-economic-technical systems which we must understand to design a secure future for the nation and the world. Perturbations/disruptions in CASoS have the potential for far-reaching effects due to highly-saturated interdependencies and allied vulnerabilities to cascades in associated systems. The Phoenix initiative approaches this high-impact problem space as engineers, devising interventions (problem solutions) that influence CASoS to achieve specific aspirations. CASoS embody the world's biggest problems and greatest opportunities: applications to real world problems are the driving force of our effort. We are developing engineering theory and practice together to create a discipline that is grounded in reality, extends our understanding of how CASoS behave, and allows us to better control those behaviors. Through application to real-world problems, Phoenix is evolving CASoS Engineering principles while growing a community of practice and the CASoS engineers to populate it.

    Complex Adaptive Systems of Systems, or CASoS, are vastly complex ecological, sociological, economic and/or technical systems which must be recognized and reckoned with to design a secure future for the nation and the world. Design within CASoS requires the fostering of a new discipline, CASoS Engineering, and the building of capability to support it. Towards this primary objective, we created the Phoenix Pilot as a crucible from which systemization of the new discipline could emerge. Using a wide range of applications, Phoenix has begun building both theoretical foundations and capability for: the integration of Applications to continuously build common understanding and capability; a Framework for defining problems, designing and testing solutions, and actualizing these solutions within the CASoS of interest; and an engineering Environment required for 'the doing' of CASoS Engineering. In a secondary objective, we applied CASoS Engineering principles to begin to build a foundation for design in context of Global CASoS

    Full Text Available JUSTIFICATIVA E OBJETIVOS: Os problemas com a via aérea pediátrica estão entre os maiores desafios que o anestesiologista pode encontrar em sua prática clínica. Dentre eles, destaca-se o laringoespasmo, que ocorre com freqüência duas a três vezes maior na população pediátrica. O objetivo deste trabalho foi relatar o tratamento de laringoespasmo realizado com digitopressão de ponto localizado atrás do lóbulo da orelha. A técnica é fácil, antiga, porém pouco divulgada. Pode ser utilizada de forma segura e rápida, dispensando o acesso venoso periférico que, em algumas situações, pode estar ausente. RELATO DOS CASOS: Dois casos de anestesia pediátrica em pacientes de 3 anos e de 6 meses de idade, nos quais ocorreu laringoespasmo. Ambos foram tratados apenas com a digitopressão da depressão retroauricular e evoluíram com pronta melhora do padrão respiratório e da saturação arterial de oxigênio. Como o laringoespasmo é complicação comum e potencialmente grave pela sua morbimortalidade, é necessário tratamento seguro, eficaz e rápido. CONCLUSÃO: O tratamento clássico do laringoespasmo é a administração de oxigênio a 100% com pressão positiva por unidade ventilatória (balão e máscara e, se não houver resposta, administração venosa de 0,25 a 1 mg.kg-1 de succinilcolina. A técnica apresentada para tratamento do laringoespasmo é fácil, segura e eficaz, e realizada com digitopressão bilateral da região localizada atrás do lóbulo das orelhas. O laringoespasmo cedeu em poucos segundos e os pacientes tiveram evolução favorável.JUSTIFICATIVA Y OBJETIVOS: Los problemas con la vía aérea pediátrica están entre los más grandes retos que el anestesiólogo puede encontrar en su práctica clínica.

    Full Text Available Comportamentos de brincadeira são fáceis de identificar, mas difíceis de definir. Sua ocorrência é mais freqüente em animais jovens, apresentando algumas características comuns: falta de função aparente, utilização de comportamentos específicos da espécie de forma exagerada em intensidade ou número de repetições. Estudamos a brincadeira em uma espécie pouco conhecida, o boto cinza, durante 18 meses, na Praia de Pipa, RN. Definimos seis categorias de brincadeira: com objeto, de forrageio, locomotora, surf, social e de impulsão. Os comportamentos descritos ocorreram quando havia filhotes nos grupos observados. Sugerimos que alguns tipos de brincadeira possibilitam o exercício da musculatura, enquanto que outras também permitem o desenvolvimento de relações sociais. A brincadeira com objetos e de forrageio treinam o animal para a pesca, habilidade complexa que deve dominar antes de se tornar independente. Nossos dados sugerem que, à semelhança dos mamíferos terrestres, nos mamíferos aquáticos a brincadeira tem função adaptativa, preparando o indivíduo para a vida adulta.Play behavior are easy to identify but difficult to define. It is more frequently displayed by young animals and present some distinguished characteristics: no apparent function and exaggerated repetition or intensity of species-specific behaviors. We studied play behavior in a scarcely studied species, the tucuxi, during 18 months at Pipa, RN, Brazil . We defined six categories: object, foraging, locomotor, social and impulsion play plus surf. The behaviors described occurred only when immatures were present in the observed groups. We suggest that some kinds of play exercise the muscles while others also allow for the development of social interactions. Object and foraging play are opportunities for training of fishing abilities which the animal must master before becoming independent. Our data suggest that, like terrestrial mammals, in marine mammals

    The recent studies of pattern mining have given more attention to discovering patterns that are interesting, significant, discriminative and so forth, than simply frequent. Does this imply that the frequent patterns are not useful anymore? In this paper we carry out a survey of frequent pattern mining and, using an empirical study, show how far the frequent pattern mining is useful in building predictive models.

    Full Text Available As queratodermias palmo-plantares familiares são doenças pouco comuns. As manifestações clínicas são variadas e exuberantes, atraindo a atenção dos dermatologistas. Apesar de sua maioria ser limitada à pele, algumas apresentam repercussões clínicas sistêmicas, sobretudo em derivados ectodérmicos. Devido à variabilidade clínica, bem como a mecanismos etiopatogênicos mal compreendidos, diversas classificações têm sido propostas. Nenhuma apresenta total aceitação universal, sendo comum a discordância entre os diversos autores no que diz respeito não só às classificações, mas também com relação à existência de alguns tipos de queratodermia reconhecidos ora como variantes, ora como nova entidade. Recentemente, a melhor compreensão da estrutura e dinâmica da epiderme, em especial o citoesqueleto celular, o sistema de adesão intercelular e a ultra-estrutura da membrana basal, tem permitido elucidar de forma concreta a origem de tais processos. O citoesqueleto, sobretudo as citoqueratinas, tem sido alvo freqüente de estudos e identificado como responsável por muitas das queratodermias palmo-plantares. O presente caso refere-se a paciente com queratodermia palmo-plantar difusa, não transgressiva, iniciada na infância, com diversos casos familiares. A avaliação clínico-histopatológica permitiu o diagnóstico de hiperqueratose epidermolítica de Vörner.

Managing these factors and improving communication (skills were regarded as solutions to reduce frequent sickness absence.The JD-R model provided a framework for determinants of and solutions to frequent sickness absence. Additional determinants were poor health, chronic illness, unhealthy lifestyles, and diminished feeling of responsibility to attend work in cases of low job resources. Frequent sickness absence should be regarded as a signal that something is wrong. Managers, supervisors, and occupational health care providers should advise and support frequent absentees to accommodate job demands, increase both job and personal resources, and improve health rather than express disapproval of frequent sickness absence and apply pressure regarding work attendance.

    Full Text Available Problem Statement: In today's life, the mining of frequent patterns is a basic problem in data mining applications. The algorithms which are used to generate these frequent patterns must perform efficiently. The objective was to propose an effective algorithm which generates frequent patterns in less time. Approach: We proposed an algorithm which was based on hashing technique and combines a vertical tidset representation of the database with effective pruning mechanisms. It removes all the non-maximal frequent item-sets to get exact set of MFI directly. It worked efficiently when the number of item-sets and tid-sets is more. Results: The performance of our algorithm had been compared with recently developed MAFIA algorithm and the results show how our algorithm gives better performance. Conclusions: Hence, the proposed algorithm performs effectively and generates frequent patterns faster.

    Full Text Available Homelessness, HIV, and substance use are interwoven problems. Furthermore, homeless individuals are frequent users of emergency services. The main purpose of this study was to identify risk factors for frequent emergency room (ER visits and to examine the effects of housing status and HIV serostatus on ER utilization. The second purpose was to identify risk factors for frequent ER visits in patients with a history of illicit drug use.A retrospective analysis was performed on 412 patients enrolled in a Boston-based health care for the homeless program (HCH. This study population was selected as a 2:1 HIV seronegative versus HIV seropositive match based on age, sex, and housing status. A subgroup analysis was performed on 287 patients with history of illicit drug use. Chart data were analyzed to compare demographics, health characteristics, and health service utilization. Results were stratified by housing status. Logistic models using generalized estimating equations were used to predict frequent ER visits.In homeless patients, hepatitis C was the only predictor of frequent ER visits (OR 4.49, p<0.01. HIV seropositivity was not predictive of frequent ER visits. In patients with history of illicit drug use, mental health (OR 2.53, 95% CI 1.07-5.95 and hepatitis C (OR 2.85, 95% CI 1.37-5.93 were predictors of frequent ER use. HIV seropositivity did not predict ER use (OR 0.45, 95% CI 0.21 - 0.97.In a HCH population, hepatitis C predicted frequent ER visits in homeless patients. HIV seropositivity did not predict frequent ER visits, likely because HIV seropositive HCH patients are engaged in care. In patients with history of illicit drug use, hepatitis C and mental health disorders predicted frequent ER visits. Supportive housing for patients with mental health disorders and hepatitis C may help prevent unnecessary ER visits in this population.

    Full Text Available Uma paciente com evidência de ruptura de aneurisma da artéria pericalosa esquerda e formação de hematoma envolvendo a fissura interhemisférica e região paramediana do hemisfério esquerdo apresentou inicialmente quadro de mutismo que evoluiu para afasia caracterizada por ausência de fala espontânea, relativa preservação da capacidade de repetição e evidente preservação da compreensão. O quadro corresponde à chamada "afasia motora trans-cortical". A paciente apresentou acentuada melhora, em curto espaço de tempo, após a drenagem do hematoma. A possibilidade de que lesão da região paramediana do hemisfério cerebral dominante possa provocar afasia é pouco conhecida e muitos casos são provavelmente mal diagnosticados, devido à transitoriedade dos principais sintomas e à confusão com demência não específica.

    2009-01-01

    A frequent trajectory patterns mining algorithm is proposed to learn the object activities and classify the trajectories in intelligent visual surveillance system. The distribution patterns of the trajectories were generated by an Apriori based frequent patterns mining algorithm and the trajectories were classified by the frequent trajectory patterns generated. In addition, a fuzzy c-mcans (FCM) based learning algorithm and a mean shift based clustering procedure were used to construct the representation of trajectories. The algorithm can be further used to describe activities and identify anomalies. The experiments on two real scenes show that the algorithm is effective.

    Complex Adaptive Systems of Systems, or CASoS, are vastly complex physical-socio-technical systems which we must understand to design a secure future for the nation. The Phoenix initiative implements CASoS Engineering principles combining the bottom up Complex Systems and Complex Adaptive Systems view with the top down Systems Engineering and System-of-Systems view. CASoS Engineering theory and practice must be conducted together to develop a discipline that is grounded in reality, extends our understanding of how CASoS behave and allows us to better control the outcomes. The pull of applications (real world problems) is critical to this effort, as is the articulation of a CASoS Engineering Framework that grounds an engineering approach in the theory of complex adaptive systems of systems. Successful application of the CASoS Engineering Framework requires modeling, simulation and analysis (MS and A) capabilities and the cultivation of a CASoS Engineering Community of Practice through knowledge sharing and facilitation. The CASoS Engineering Environment, itself a complex adaptive system of systems, constitutes the two platforms that provide these capabilities.

    2011-09-01

    Full Text Available In this paper a new mining algorithm is defined based on frequent item set. Apriori Algorithm scans the database every time when it finds the frequent item set so it is very time consuming and at each step it generates candidate item set. So for large databases it takes lots of space to store candidate item set. The defined algorithm scans the database at the start only once and then makes the undirected item set graph. From this graph by considering minimum support it finds the frequent item set and by considering the minimum confidence it generates the association rule. If database and minimum support is changed, the new algorithm finds the new frequent items by scanning undirected item set graph. That is why it’s executing efficiency is improved distinctly compared to traditional algorithm.

  8. Incremental Mining for Regular Frequent Patterns in Vertical Format

    Vijay Kumar G

    2013-04-01

    Full Text Available In the real world database updates continuously in several online applications like super market, network monitoring, web administration, stock market etc. Frequent pattern mining is afundamental and essential area in data mining research. Not only occurrence frequency of a pattern but also occurrence behaviour of a pattern may be treated as important criteria to measure the interestingness of a pattern. A frequent pattern is said to be regular frequent if the occurrence behaviour is less than or equal to the user given regularity threshold. In incremental transactional databases the occurrence frequency and the occurrence behaviour of a pattern changes whenever a small set of new transactions are added to the database. It is undesirable to mine regular frequent patterns from the scratch. Thus proposes a new algorithm called RFPID (Regular Frequent Pattern Mining in Incremental Databases to mine regular frequent patterns in incremental transactional databases using vertical data format which requires only one database scan. The experimental results show our algorithm is efficient in both memory utilization and execution.

    2006-01-01

    Becausemining complete set of frequent patterns from dense database could be impractical, an interesting alternative has been proposed recently. Instead of mining the complete set of frequent patterns, the new model only finds out the maximal frequent patterns, which can generate all frequent patterns. FP-growth algorithm is one of the most efficient frequent-pattern mining methods published so far. However,because FP-tree and conditional FP-trees must be two-way traversable, a great deal memory is needed in process of mining. This paper proposes an efficient algorithm Unid_FP-Max for mining maximal frequent patterns based on unidirectional FP-tree. Because of generation method of unidirectional FP-tree and conditional unidirectional FP-trees, the algorithm reduces the space consumption to the fullest extent. With the development of two techniques:single path pruning and header table pruning which can cut down many conditional unidirectional FP-trees generated recursively in mining process, Unid_ FP-Max further lowers the expense of time and space.

  12. Mining Frequent Generalized Itemsets and Generalized Association Rules Without Redundancy

    Institute of Scientific and Technical Information of China (English)

    Daniel Kunkle; Donghui Zhang; Gene Cooperman

    2008-01-01

    This paper presents some new algorithms to efficiently mine max frequent generalized itemsets (g-itemsets) and essential generalized association rules (g-rules). These are compact and general representations for all frequent patterns and all strong association rules in the generalized environment. Our results fill an important gap among algorithms for frequent patterns and association rules by combining two concepts. First, generalized itemsets employ a taxonomy of items, rather than a fiat list of items. This produces more natural frequent itemsets and associations such as (meat, milk) instead of (beef, milk), (chicken, milk), etc. Second, compact representations of frequent itemsets and strong rules, whose result size is exponentially smaller, can solve a standard dilemma in mining patterns: with small threshold values for support and confidence, the user is overwhelmed by the extraordinary number of identified patterns and associations; but with large threshold values, some interesting patterns and associations fail to be identified. Our algorithms can also expand those max frequent g-itemsets and essential g-rules into the much larger set of ordinary frequent g-itemsets and strong g-rules. While that expansion is not recommended in most practical cases, we do so in order to present a comparison with existing algorithms that only handle ordinary frequent g-itemsets. In this case, the new algorithm is shown to be thousands, and in some cases millions, of the time faster than previous algorithms. Further, the new algorithm succeeds in analyzing deeper taxonomies, with the depths of seven or more. Experimental results for previous algorithms limited themselves to taxonomies with depth at most three or four. In each of the two problems, a straightforward lattice-based approach is briefly discussed and then a classificationbased algorithm is developed. In particular, the two classification-based algorithms are MFGI_class for mining max frequent g-itemsets and EGR

    This article reports the frequency of the use of coping scales in academic journals published from 1998 to 2010. Two thousand empirical journal articles were selected from the EBSCO database. The COPE, Ways of Coping Questionnaire, Coping Strategies Questionnaire, Coping Inventory for Stressful Situations, Religious-COPE and Coping Response Inventory were frequently mentioned. In particular, the COPE (20.2%) and Ways of Coping Questionnaire (13.6%) were used the most frequently. In this literature reviewed, coping scales were most often used to assess coping with health issues (e.g. illness, pain and medical diagnoses) over other types of stressors, and patients were the most frequent participants. Further, alpha coefficients were estimated for the COPE subscales, and correlations between the COPE subscales and coping outcomes were calculated, including depressive symptoms, anxiety, negative affect, psychological distress, physical symptoms and well-being.

    Mining frequent patterns from datasets is one of the key success of data mining research. Currently, most of the studies focus on the data sets in which the elements are independent, such as the items in the marketing basket.. However, the objects in the real world often have close relationship with each other. How to extract frequent patterns from these relations is the objective of this paper. The authors use graphs to model the relations, and select a simple type for analysis. Combining the graph theory and algorithms to generate frequent patterns, a new algorithm called Topology, which can mine these graphs efficiently, has been proposed. The performance of the algorithm is evaluated by doing experiments with synthetic datasets and real data. The experimental results show that Topology can do the job well. At the end of this paper, the potential improvement is mentioned.

    There is a considerable body of work on sequence mining of Web Log Data. We are using One Pass frequent Episode discovery (or FED) algorithm, takes a different approach than the traditional apriori class of pattern detection algorithms. In this approach significant intervals for each Website are computed first (independently) and these interval used for detecting frequent patterns/Episode and then the Analysis is performed on Significant Intervals and frequent patterns That can be used to forecast the user's behavior using previous trends and this can be also used for advertising purpose. This type of applications predicts the Website interest. In this approach, time-series data are folded over a periodicity (day, week, etc.) Which are used to form the Interval? Significant intervals are discovered from these time points that satisfy the criteria of minimum confidence and maximum interval length specified by the user.

    Full Text Available In modern life, interactions between human beings are frequently occurring in meetings, where topics are discussed and new decisions are made. To understand and interpret how people interact in a meeting discussion study of semantic knowledge is important. It becomes possible to extract frequent patterns of human interaction based on the captured content of face-to-face meetings by using mining method. Human interactions are categorized as proposing an idea, giving comments, expressing a positive opinion, acknowledgement; indicate the intention of user towards a topic or role in a discussion.Tree is used for representing a human interaction flow in a discussion session. Tree-based interaction mining algorithms are studied to analyze the structures of the trees and to extract interaction flow patterns. It can successfully extract several interesting patterns which is useful for the interpretation of human behavior in meeting discussions, such as determining frequent interactions, typical interaction flows, and relationships between different types of interactions.

    Full Text Available Discovering frequent objects (item sets, sequential patterns is one of the most vital fields in data mining. It is well understood that it require running time and memory for defining candidates and this is the motivation for developing large number of algorithm. Frequent patterns mining is the paying attention research issue in association rules analysis. Apriori algorithm is a standard algorithm of association rules mining. Plenty of algorithms for mining association rules and their mutations are projected on the foundation of Apriori Algorithm. Most of the earlier studies adopted Apriori-like algorithms which are based on generate-and-test candidates theme and improving algorithm approach and formation but no one give attention to the structure of database. Several modifications on apriori algorithms are focused on algorithm Strategy but no one-algorithm emphasis on least transaction and more attribute representation of database. We presented a new research trend on frequent pattern mining in which generate Transaction pair to lighten current methods from the traditional blockage, providing scalability to massive data sets and improving response time. In order to mine patterns in database with more columns than rows, we proposed a complete framework for the frequent pattern mining. A simple approach is if we generate pair of transaction instead of item id where attributes are much larger then transaction so result is very fast. Newly, different works anticipated a new way to mine patterns in transposed databases where there is a database with thousands of attributes but merely tens of stuff. We suggest a novel dynamic algorithm for frequent pattern mining in which generate transaction pair and for generating frequent pattern we find out by longest common subsequence using dynamic function. Our solutions give result more rapidly. A quantitative investigation of these tradeoffs is conducted through a wide investigational study on artificial and

    The effective construction of many association rule bases requires the computation of both frequent closed and frequent generator itemsets (FCIs/FGs). However, only few miners address both concerns, typically by applying levelwise breadth-first traversal. As depth-first traversal is known to be superior, we examine here the depth-first FCI/FG-mining. The proposed algorithm, Touch, deals with both tasks separately, i.e., uses a well-known vertical method, Charm, to extract FCIs and a novel one...

    Recent literature is explored focusing on the relationship between symptoms of anorexia nervosa (AN) and other psychiatric disorders and lines of treatment. In AN, restrictive subtype, anxiety and obsessive-compulsive disorders are the most frequent co-morbidities. In AN, bulimic subtype, depression, emotional instability/borderline and dependency disorders are most frequent. Psychopharmacological treatment could be tried in cases with AN and co-morbid depression, but otherwise the evidence base is lacking and pharmacological treatment relies on case stories and experience.

    Full Text Available Online mining of data streams poses many new challenges more than mining static databases. In addition to the one-scan nature, the unbounded memory requirement, the high data arrival rate of data streams and the combinatorial explosion of itemsets exacerbate the mining task. The high complexity of the frequent itemsets mining problem hinders the application of the stream mining techniques. In this review, we present a comparative study among almost all, as we are acquainted, the algorithms for mining frequent itemsets from online data streams. All those techniques immolate with the accuracy of the results due to the relatively limited storage, leading, at all times, to approximated results.

  10. Frequent Subgraph Discovery in Large Attributed Streaming Graphs

    Energy Technology Data Exchange (ETDEWEB)

    Ray, Abhik; Holder, Larry; Choudhury, Sutanay

    2014-08-13

    The problem of finding frequent subgraphs in large dynamic graphs has so far only consid- ered a dynamic graph as being represented by a series of static snapshots taken at various points in time. This representation of a dynamic graph does not lend itself well to real time processing of real world graphs like social networks or internet traffic which consist of a stream of nodes and edges. In this paper we propose an algorithm that discovers the frequent subgraphs present in a graph represented by a stream of labeled nodes and edges. Our algorithm is efficient and consists of tunable parameters that can be tuned by the user to get interesting patterns from various kinds of graph data. In our model updates to the graph arrive in the form of batches which contain new nodes and edges. Our algorithm con- tinuously reports the frequent subgraphs that are estimated to be found in the entire graph as each batch arrives. We evaluate our system using 5 large dynamic graph datasets: the Hetrec 2011 challenge data, Twitter, DBLP and two synthetic. We evaluate our approach against two popular large graph miners, i.e., SUBDUE and GERM. Our experimental re- sults show that we can find the same frequent subgraphs as a non-incremental approach applied to snapshot graphs, and in less time.

    Full Text Available Research on mining frequent itemsets is one the emerging task in data mining.The purchasing of one product when another product is purchased represents an association rule. Association rules are useful for analyzing the customer behavior. It takes an important part in shopping basket data analysis, clustering. The FP-Growth algorithm is the basic algorithm for mining association rules. This paper presents an efficient algorithm for mining frequent itemsets using Two Dimensional Transactions Reduction(TDTR approach which reduces the original database(D transactions to the reduced data base transactions D1 based on the min_sup count. Then for each item it finds the number of transactions that the item present and hence find the largest frequent itemset using the two dimensional approach. Using the largest item set property ,it finds the subset of frequent item sets. Thus TDTR approach reduces the number of scans in the database and hence improve the efficiency & accuracy by finding the number of association rules and reduces time to find the rules.

  13. GRAMI: Generalized Frequent Subgraph Mining in Large Graphs

    KAUST Repository

    El Saeedy, Mohammed El Sayed

    2011-07-24

    Mining frequent subgraphs is an important operation on graphs. Most existing work assumes a database of many small graphs, but modern applications, such as social networks, citation graphs or protein-protein interaction in bioinformatics, are modeled as a single large graph. Interesting interactions in such applications may be transitive (e.g., friend of a friend). Existing methods, however, search for frequent isomorphic (i.e., exact match) subgraphs and cannot discover many useful patterns. In this paper we propose GRAMI, a framework that generalizes frequent subgraph mining in a large single graph. GRAMI discovers frequent patterns. A pattern is a graph where edges are generalized to distance-constrained paths. Depending on the definition of the distance function, many instantiations of the framework are possible. Both directed and undirected graphs, as well as multiple labels per vertex, are supported. We developed an efficient implementation of the framework that models the frequency resolution phase as a constraint satisfaction problem, in order to avoid the costly enumeration of all instances of each pattern in the graph. We also implemented CGRAMI, a version that supports structural and semantic constraints; and AGRAMI, an approximate version that supports very large graphs. Our experiments on real data demonstrate that our framework is up to 3 orders of magnitude faster and discovers more interesting patterns than existing approaches.

A pesar de estos avances, la mortalidad hospitalaria sigue siendo muy elevada. Nuestro objetivo fue analizar las características de los pacientes con endocarditis infecciosa activa y su relación con la mortalidad hospitalaria a lo largo de 16 años. Se realizó un registro prospectivo entre 1994 y 2010 de pacientes ingresados con endocarditis. Se analizaron características clínicas, evolución y tratamiento y se registraron los eventos intrahospitalarios. Ingresaron 152 pacientes, 64.5% varones, edad 45 ± 16 años, las causas más frecuentes de cardiopatía de base fueron: congénita 32 (21% y reumática 20 (13.2%. Los motivos de internación fueron síndrome febril 116 (76.3% e insuficiencia cardíaca 61 (40.1%. Se identificó el agente infeccioso en 106 (69.7% de los casos, el más frecuente fue Streptococcus viridans. El ecocardiograma mostró vegetaciones en 123 (80.9% de los pacientes y 88 (57.8% presentaron complicaciones durante su internación, siendo la más frecuente la insuficiencia cardíaca. Se indicó tratamiento quirúrgico en 96 (63.1% de los casos, fundamentalmente por insuficiencia cardíaca en 66. La mortalidad hospitalaria global fue 46 (30.2%. El desarrollo de complicaciones en la internación, la indicación de cirugía y la presencia de insuficiencia cardíaca refractaria al tratamiento fueron predictores independientes de mortalidad hospitalaria, mientras que la presencia de vegetaciones resultó un predictor independiente de mejor supervivencia. La identificación temprana de estos predictores descriptos podría ayudar a mejorar los resultados.

    Full Text Available Asthma is a major health problem affecting millions of children worldwide. The prevalence of asthmain children tends to increase annually in the world. Therefore, identification of the prognostic factorsfor episodic asthma is important to perform early prevention of asthma attacks in children. Thestudy was performed to identify the prognostic factors for frequent episodic asthma in children. Thiswas a retrospective cohort study involving asthmatic children who attended the Emergency Unit orOutpatient Clinic of the Department of Pediatrics, Dr. Sardjito General Hospital, Yogyakarta. Theinclusion criteria were asthmatic children aged over 7 years, suffering from asthma over 2 years andgetting agreement from their parents as expressed by signed an informed consent. The exclusioncriteria were children with other chronic obtructive pulmonary diseases beside asthma and childrenwith cardiovascular diseases. Subjects were grouped into two groups i.e. Case Group and ControlGroup. The Case Group was children with frequent episodic asthma while the Control Group waschildren with infrequent episodic asthma. Prognostic factors for episodic asthma were then gatheredby giving a questionnaire to their parents. Regression analysis was used to evaluate the relationshipbetween prognostic factors and episodic asthma. A total of 94 subjects comprising 37 (36.4%subjects with frequent episodic asthma and 57 (63.6% subjects with infrequent episodic asthmawere involved in the study. Furthermore, response to initial theraphy was significantly associatedwith frequent episodic asthma (RR= 8.64; 95%CI= 0.47-2.50; p=0.001. Whereas, nutritionalstatus, patients age when asthma diagnosed, exclusive breastfeeding, maternal education, exposureof secondhand smoke and welfare were not (p>0.05.

O objetivo desse estudo foi avaliar os casos notificados de dengue no município de Duque de Caxias (Rio de Janeiro, Brasil em seus quatro Distritos Sanitários, durante oito anos, compreendendo o período de 2007 a 2014. Essa região apresenta inúmeros problemas relacionados a processo de ocupação desordenada, densidade demográfica e altos índices de violência urbana e o município é organizado em quatro distritos. Os casos de dengue notificados à Secretaria Municipal de Saúde de Duque de Caxias e registrados na base municipal do SINAN (Sistema Nacional de Agravos de Notificação, referentes ao período de 2007 a 2014 foram utilizados neste estudo. Em 2008, 2011 e 2013, observou-se uma epidemia no município, que em 2008 tomou magnitude ainda maior e alcançou incidência de mais de mil casos a cada 100 mil habitantes. No período de 2009 e 2014, houve uma queda das incidências observadas, caracterizando-o como interepidêmico. Em relação aos casos de dengue em cada distrito, o primeiro e segundo distritos foram os que tiveram maior número de casos da doença, enquanto o quarto distrito foi o que teve menor número de casos em todos os anos estudados. Possivelmente, pelo fato do 1º distrito (Centro ter a maior parte das habitações e o 2º distrito (Campos Elíseos, abrigar as indústrias.

Métodos Estudo do tipo caso-controle em uma emergência geral de um hospital público, na cidade do Recife com 220 indivíduos, distribuídos em dois grupos de 110 pacientes cada, que estavam em tratamento, sendo o grupo casos os sobreviventes de tentativa de suicídio por envenenamento e os controles, sem história de intoxicação/envenenamento nem tentativa de suicídio, pareados por gênero e idade. Resultados O gênero feminino predominou na amostra (70,9%, com idade média de 29 anos; 73% declararam etnia branca ou morena; menos da metade vivia em convívio marital; a maioria tinha religião; ambos tinham poucos anos de estudo. Houve diferença significativa (p = 0,003 para dependência financeira entre os grupos, com chance 2,25 vezes maior para tentar suicídio entre os casos. Ter sofrido fatos traumáticos e abuso sexual na infância revelou diferença significativa. Conclusões Foram considerados indicadores de risco no grupo caso: estar em dependência financeira de terceiros, ter sofrido abuso sexual na infância, ideação suicida, histórico de transtorno mental na família, possuir algum transtorno mental e, principalmente, comorbidade(s psiquiátrica(s. No modelo de regressão, foi possível estimar uma chance de tentativa de suicídio por envenenamento de até 94,0% na presença conjunta de quatro fatores. A pesquisa representa uma das primeiras iniciativas para ampliação das discussões sobre os fatores de risco para tentativa de suicídio em âmbito nacional.

    Full Text Available In this paper we propose an algorithm to identify sets of the most frequently visited tourist sites. We do this by examining the trajectories followed by tourists and by considering their visits to these sites. We propose a second algorithm that recommends a specific order to visit these sites. To accomplish this task, we consider variables such as tourist preferences, departure and arrival locations, and time constraints. To validate our proposal, a prototype website application was developed, which experiments with real vehicle trajectories in Rio de Janeiro. Although more exhaustive experiments will be required to deal with different possible scenarios, preliminary results show the usefulness of our proposal for displaying sets of neighborhoods frequented by vehicles as they move about a city.

  7. Mining Multi-Level Frequent Itemsets under Constraints

    2010-01-01

    Mining association rules is a task of data mining, which extracts knowledge in the form of significant implication relation of useful items (objects) from a database. Mining multilevel association rules uses concept hierarchies, also called taxonomies and defined as relations of type 'is-a' between objects, to extract rules that items belong to different levels of abstraction. These rules are more useful, more refined and more interpretable by the user. Several algorithms have been proposed in the literature to discover the multilevel association rules. In this article, we are interested in the problem of discovering multi-level frequent itemsets under constraints, involving the user in the research process. We proposed a technique for modeling and interpretation of constraints in a context of use of concept hierarchies. Three approaches for discovering multi-level frequent itemsets under constraints were proposed and discussed: Basic approach, "Test and Generate" approach and Pruning based Approach.

    As breeding between relatives often results in inbreeding depression, inbreeding avoidance is widespread in the animal kingdom. However, inbreeding avoidance may entail fitness costs. For example, dispersal away from relatives may reduce survival. How these conflicting selection pressures are resolved is challenging to investigate, but theoretical models predict that inbreeding should occur frequently in some systems. Despite this, few studies have found evidence of regular incest in mammals, even in social species where relatives are spatio-temporally clustered and opportunities for inbreeding frequently arise. We used genetic parentage assignments together with relatedness data to quantify inbreeding rates in a wild population of banded mongooses, a cooperatively breeding carnivore. We show that females regularly conceive to close relatives, including fathers and brothers. We suggest that the costs of inbreeding avoidance may sometimes outweigh the benefits, even in cooperatively breeding species where strong within-group incest avoidance is considered to be the norm.

    Data Stream Mining algorithms performs under constraints called space used and time taken, which is due to the streaming property. The relaxation in these constraints is inversely proportional to the streaming speed of the data. Since the caching and mining the streaming-data is sensitive, here in this paper a scalable, memory efficient caching and frequent itemset mining model is devised. The proposed model is an incremental approach that builds single level multi node trees called bushes fr...

    The Apriori algorithm is a classical algorithm for the frequent itemset mining problem. A significant bottleneck in Apriori is the number of I/O operation involved, and the number of candidates it generates. We investigate the role of LSH techniques to overcome these problems, without adding much computational overhead. We propose randomized variations of Apriori that are based on asymmetric LSH defined over Hamming distance and Jaccard similarity.

    2015-11-01

    Recent reports suggested frequent occurrence of cancer associated somatic mutations within regulatory elements of the genome. Based on initial exome sequencing of 21 melanomas, we report frequent somatic mutations in skin cancers in a bidirectional promoter of diphthamide biosynthesis 3 (DPH3) and oxidoreductase NAD-binding domain containing 1 (OXNAD1) genes. The UV-signature mutations occurred at sites adjacent and within a binding motif for E-twenty six/ternary complex factors (Ets/TCF), at -8 and -9 bp from DPH3 transcription start site. Follow up screening of 586 different skin lesions showed that the DPH3 promoter mutations were present in melanocytic nevi (2/114; 2%), melanoma (30/304; 10%), basal cell carcinoma of skin (BCC; 57/137; 42%) and squamous cell carcinoma of skin (SCC; 12/31; 39%). Reporter assays carried out in one melanoma cell line for DPH3 and OXNAD1 orientations showed statistically significant increased promoter activity due to -8/-9CC > TT tandem mutations; although, no effect of the mutations on DPH3 and OXNAD1 transcription in tumors was observed. The results from this study show occurrence of frequent somatic non-coding mutations adjacent to a pre-existing binding site for Ets transcription factors within the directional promoter of DPH3 and OXNAD1 genes in three major skin cancers. The detected mutations displayed typical UV signature; however, the functionality of the mutations remains to be determined. PMID:26416425

  17. Handling Dynamic Weights in Weighted Frequent Pattern Mining

    Ahmed, Chowdhury Farhan; Tanbeer, Syed Khairuzzaman; Jeong, Byeong-Soo; Lee, Young-Koo

    Even though weighted frequent pattern (WFP) mining is more effective than traditional frequent pattern mining because it can consider different semantic significances (weights) of items, existing WFP algorithms assume that each item has a fixed weight. But in real world scenarios, the weight (price or significance) of an item can vary with time. Reflecting these changes in item weight is necessary in several mining applications, such as retail market data analysis and web click stream analysis. In this paper, we introduce the concept of a dynamic weight for each item, and propose an algorithm, DWFPM (dynamic weighted frequent pattern mining), that makes use of this concept. Our algorithm can address situations where the weight (price or significance) of an item varies dynamically. It exploits a pattern growth mining technique to avoid the level-wise candidate set generation-and-test methodology. Furthermore, it requires only one database scan, so it is eligible for use in stream data mining. An extensive performance analysis shows that our algorithm is efficient and scalable for WFP mining using dynamic weights.

    Full Text Available Arterial variations of the femoral triangle are rarely reported in the literature. In the present article, we have reported a case of high origin of the deep femoral artery, which was originating just lower to the inguinal ligament. It was also observed that the lateral circumflex femoral artery arose directly from the femoral artery instead from the deep femoral artery. We have discussed the anatomy, embryological basis, and clinical implications of these variations along with relevant literature review. The importance of knowledge about these variations in therapeutic and diagnostic interventions is discussed.Variações arteriais no triângulo femoral têm sido pouco relatadas na literatura. No presente artigo, relatou-se um caso de origem alta da artéria femoral profunda, que estava se originando pouco abaixo do ligamento inguinal.

    This case control study was aimed to identify the predictive risk factors for frequent relapse idiopathic nephrotic syndrome (INS) and conducted in Sir Salimullah Medical College & Mitford Hospital, Dhaka and at Renal and Dialysis Unit of Dhaka Shishu Hospital and Bangladesh Institute of Child Health (BICH), Dhaka, from January 2006 to December 2006. We examined retrospectively the clinical course of fifty cases of frequent relapse nephrotic syndrome (FRNS) as cases and fifty cases of infrequent relapse nephrotic syndrome (IRNS) as control who met the predefined enrollment criteria, followed for at least one year after initial onset of disease. After enrollment following parameters were studied as predictors of frequent relapse: i) Socio-demographic variables: age, sex, socio-economic condition, number of living room ii) Disease related variables i.e. age of onset, duration of illness, frequency of relapse within the 1st year, regimen of initial steroid therapy, total cumulative dose of steroid for remission, day of remission after starting steroid, association with atopy and infection, concomitant upper respiratory illness iii) Biochemical and pathological variables (at the time of initial attack) i.e. Serum albumin, serum cholesterol, blood urea, 24 hours urinary protein, serum creatinine, complete blood count, urine RBC, urine pus cell, urine culture. The test statistics used to analyses the data were descriptive statistics, Chi-square probability test, Student's t-test and Binary logistic regression analysis for Odds ratio. Both univariate and multivariate logistic regression analysis revealed that age of onset (P<0.001, OR=0.9, 95% CI=0.85-0.95), poor socioeconomic status (P<0.034, OR=0.5.8, 95% CI=1.14-29.5) and low serum albumin level at the time of initial presentation (P<0.022, OR=0.8, 95% CI=0.65-0.97) were independent predictors of frequent relapse nephrotic syndrome. In conclusion, we demonstrated that age at onset, poor socioeconomic condition and low

    Full Text Available No final de 2011, uma campanha publicitária de lingerie, protagonizada por Gisele Bündchen, tornou-se um acontecimento ao ser denunciada pelo governo por contribuir para a manutenção das desigualdades entre homens e mulheres. No enredo da propaganda, a modelo resolve seus problemas domésticos através da sensualidade. Este artigo analisa a estrutura do acontecimento gerado pela denúncia governamental com base em textos veiculados na mídia. O objetivo não é avaliar a campanha publicitária, mas identificar em diversos textos midiáticos a maneira como a sensualidade feminina foi observada na experiência pública. A análise mostra que a condenação da ação do governo se sobrepõe ao debate das questões que envolvem a legitimidade da participação das mulheres na vida pública. Apesar da constante exaltação cultural da sensualidade feminina no Brasil, o caso pouco mobilizou o tema.

    Chordoma is a rare primary bone neoplasm that is resistant to standard chemotherapies. Despite aggressive surgical management, local recurrence and metastasis is not uncommon. To identify the specific genetic aberrations that play key roles in chordoma pathogenesis, we utilized a genome-wide high-resolution SNP-array and next generation sequencing (NGS)-based molecular profiling platform to study 24 patient samples with typical histopathologic features of chordoma. Matching normal tissues were available for 16 samples. SNP-array analysis revealed nonrandom copy number losses across the genome, frequently involving 3, 9p, 1p, 14, 10, and 13. In contrast, copy number gain is uncommon in chordomas. Two minimum deleted regions were observed on 3p within a ∼8 Mb segment at 3p21.1-p21.31, which overlaps SETD2, BAP1 and PBRM1. The minimum deleted region on 9p was mapped to CDKN2A locus at 9p21.3, and homozygous deletion of CDKN2A was detected in 5/22 chordomas (∼23%). NGS-based molecular profiling demonstrated an extremely low level of mutation rate in chordomas, with an average of 0.5 mutations per sample for the 16 cases with matched normal. When the mutated genes were grouped based on molecular functions, many of the mutation events (∼40%) were found in chromatin regulatory genes. The combined copy number and mutation profiling revealed that SETD2 is the single gene affected most frequently in chordomas, either by deletion or by mutations. Our study demonstrated that chordoma belongs to the C-class (copy number changes) tumors whose oncogenic signature is non-random multiple copy number losses across the genome and genomic aberrations frequently alter chromatin regulatory genes. © 2016 Wiley Periodicals, Inc.

    Full Text Available O presente estudo investiga as principais causas do fechamento precoce das lojas de um shopping center de uma capital brasileira e tenta identificar a utilização das ferramentas mercadológicas pelos proprietários de pequenos negócios, a fim de lhes proporcionar melhor gestão dessa atividade. Para isso, foram analisados os vários fatores que levam as microempresas encerrarem suas atividades com pouco tempo de mercado. Utilizou-se um estudo de caso por meio de pesquisa descritiva, utilizando-se entrevistas, tanto com lojistas em funcionamento quanto com ex-lojistas do shopping, a fim de permitir uma comparação dos dois tipos de gestão. Os resultados indicam ausência de um plano de negócios antes da abertura da loja, falta de planejamento de marketing, insatisfação dos lojistas com a gestão do shopping, falta de mix apropriado de oferta do shopping, desconhecimento do público-alvo da loja, dentre outros fatores de fechamento precoce das lojas. Recomenda-se maior preparação dos gestores para lidar com situações difíceis e maior habilidade na gestão da loja. Finalmente, é imprescindível a elaboração de um plano de negócio antes da abertura da loja, para saber se é viável ou não sua instalação.

    Most of the existing text clustering algorithms overlook the fact that one document is a word sequence with semantic information.There is some important semantic information existed in the positions of words in the sequence.In this paper, a novel method named Frequent Itemset-based Clustering with Window (FICW) was proposed, which makes use of the semantic information for text clustering with a window constraint.The experimental results obtained from tests on three (hypertext) text sets show that FICW outperforms the method compared in both clustering accuracy and efficiency.

  17. Do short, frequent DNA sequence motifs mould the epigenome?

    Science.gov (United States)

    Quante, Timo; Bird, Adrian

    2016-04-01

    'Epigenome' refers to the panoply of chemical modifications borne by DNA and its associated proteins that locally affect genome function. Epigenomic patterns are thought to be determined by external constraints resulting from development, disease and the environment, but DNA sequence is also a potential influence. We propose that domains of relatively uniform DNA base composition may modulate the epigenome through cell type-specific proteins that recognize short, frequent sequence motifs. Differential recruitment of epigenomic modifiers may adjust gene expression in multigene blocks as an alternative to tuning the activity of each gene separately, thus simplifying gene expression programming.

    2014-01-01

    This paper presents a brief, semi-technical comparison of the essential features of the frequentist and Bayesian approaches to statistical inference, with several illustrative examples implemented in Python. The differences between frequentism and Bayesianism fundamentally stem from differing definitions of probability, a philosophical divide which leads to distinct approaches to the solution of statistical problems as well as contrasting ways of asking and answering questions about unknown parameters. After an example-driven discussion of these differences, we briefly compare several leading Python statistical packages which implement frequentist inference using classical methods and Bayesian inference using Markov Chain Monte Carlo.

    Full Text Available Data Stream Mining algorithms performs under constraints called space used and time taken, which is due to the streaming property. The relaxation in these constraints is inversely proportional to the streaming speed of the data. Since the caching and mining the streaming-data is sensitive, here in this paper a scalable, memory efficient caching and frequent itemset mining model is devised. The proposed model is an incremental approach that builds single level multi node trees called bushes from each window of the streaming data; henceforth we refer this proposed algorithm as a Tree (bush based Incremental Frequent Itemset Mining (TIFIM over data streams. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

  4. Graph Based New Approach for Frequent Pattern Mining

    Full Text Available Association rule mining is a function of data mining research domain and frequent pattern mining is anessential part of it. Most of the previous studies on mining frequent patterns based on an Apriori approach, which required more number of database scans and operations for counting pattern supports in the database. Since the size of each set of transaction may be massive that it makes difficult to perform traditional data mining tasks. This research intends to propose a graph structure that captures only those itemsets that needs to define a sufficiently immense dataset into a submatrix representing important weights and does not give any chance to outliers. We have devised a strategy that covers significant facts of data by drilling down the large data into a succinct form of an Adjacency Matrix at different stages of mining process. The graph structure is so designed that it can be easily maintained and the trade off in compressing the large data values is reduced. Experimental results show the effectiveness of our graphbased approach.

  5. WEB DOCUMENT SEGMENTATION USING FREQUENT TERM SETS FOR SUMMARIZATION

    2012-01-01

    Full Text Available Query sensitive summarization aims at extracting the query relevant contents from web documents. Web page segmentation focuses on reducing the run time overhead of the summarization systems by grouping the related contents of a web page into segments. At query time, query relevant segments of the web page are identified and important sentences from these segments are extracted to compose the summary. DOM tree structures of the web documents are utilized to perform the segmentation of the contents. Leaf nodes of DOM tress are merged to form segments according to the statistical and linguistic similarity measure. The proposed system has been evaluated by intrinsic approach making use of user satisfaction index. The performance of the system is compared with summarization without using preprocessed segments. Performance of this system is more promising than the other measures like cosine similarity, jaccard measure which make use of sparse term-frequent vectors, since the most frequent term sets are considered to measure the relevance. Relevant segments alone need to be processed at run time for summarization which reduces the time complexity of the summarization process.

    Ectotherms depend on the environmental temperature for thermoregulation and exploit thermal regimes that optimise physiological functioning. They may also frequent warmer conditions to up-regulate their immune response against parasite infection and/or impede parasite development. This adaptive response, known as 'behavioural fever', has been documented in various taxa including insects, reptiles and fish, but only in response to endoparasite infections. Here, a choice chamber experiment was used to investigate the thermal preferences of a tropical freshwater fish, the Trinidadian guppy (Poecilia reticulata), when infected with a common helminth ectoparasite Gyrodactylus turnbulli, in female-only and mixed-sex shoals. The temperature tolerance of G. turnbulli was also investigated by monitoring parasite population trajectories on guppies maintained at a continuous 18, 24 or 32 °C. Regardless of shoal composition, infected fish frequented the 32 °C choice chamber more often than when uninfected, significantly increasing their mean temperature preference. Parasites maintained continuously at 32 °C decreased to extinction within 3 days, whereas mean parasite abundance increased on hosts incubated at 18 and 24 °C. We show for the first time that gyrodactylid-infected fish have a preference for warmer waters and speculate that sick fish exploit the upper thermal tolerances of their parasites to self medicate.

Observou-se tendência inversa entre a ocorrência de institucionalização do idoso e o nível de atividade física, em que sujeitos pouco ativos e inativos apresentaram maiores probabilidades de institucionalização (OR = 1,71 e OR = 4,73, respectivamente. CONCLUSÕES: Dentre todas as características investigadas nos idosos, idade > 80 anos, viver sem companheiro e ser fisicamente inativo foram os indicadores mais fortemente associados à ocorrência de institucionalização. O incentivo ao cuidado informal, a partir de ações educativas e culturais focadas no papel da família para o idoso, pode impedir a institucionalização desses indivíduos.

    Full Text Available Abstract Background General Practitioners spend a disproportionate amount of time on frequent attenders. So far, trials on the effect of interventions on frequent attenders have shown negative results. However, these trials were conducted in short-term frequent attenders. It would be more reasonable to target intervention at persistent frequent attenders. Typical characteristics of persistent frequent attenders, as opposed to 1-year frequent attenders and non-frequent attenders, may generate hypotheses regarding modifiable factors on which new randomized trials may be designed. Methods We used the data of all 28,860 adult patients from 5 primary healthcare centers. Frequent attenders were patients whose attendance rate ranked in the (age and sex adjusted top 10 percent during 1 year (1-year frequent attenders or 3 years (persistent frequent attenders. All other patients on the register over the 3-year period were referred to as non-frequent attenders. The lists of medical problems coded by the GP using the International Classification of Primary Care (ICPC were used to assess morbidity. First, we determined which proportion of 1-year frequent attenders was still a frequent attender during the next two consecutive years and calculated the GPs' workload for these patients. Second, we compared morbidity and number of prescriptions for non-frequent attenders, 1-year frequent attenders and persistent frequent attenders. Results Of all 1-year frequent attenders, 15.4% became a persistent frequent attender equal to 1.6% of all patients. The 1-year frequent attenders (3,045; 10.6% were responsible for 39% of the face-to-face consultations; the 470 patients who would become persistent frequent attenders (1.6% were responsible for 8% of all consultations in 2003. Persistent frequent attenders presented more social problems, more psychiatric problems and medically unexplained physical symptoms, but also more chronic somatic diseases (especially diabetes

    Pattern detection is an inherent task in the analysis and interpretation of complex and continuously accumulating biological data. Numerous itemset mining algorithms have been developed in the last decade to efficiently detect specific pattern classes in data. Although many of these have proven their value for addressing bioinformatics problems, several factors still slow down promising algorithms from gaining popularity in the life science community. Many of these issues stem from the low user-friendliness of these tools and the complexity of their output, which is often large, static, and consequently hard to interpret. Here, we apply three software implementations on common bioinformatics problems and illustrate some of the advantages and disadvantages of each, as well as inherent pitfalls of biological data mining. Frequent itemset mining exists in many different flavors, and users should decide their software choice based on their research question, programming proficiency, and added value of extra features.

    2013-05-01

    conditions with which candidate assemblies may be assessed and filtered. It turns out that a core challenge of assembly detection is multiple testing, which causes a large number of false discoveries. Unfortunately, criteria that address individual candidate assemblies and try to assess them with statistical tests and/or subset conditions do not help much to tackle this problem. The core idea of our method is to shift the focus of statistical testing from specific assemblies (consisting of a specific set of neurons to spike patterns of a certain size (i.e. with a certain number of neurons. This significantly reduces the number of necessary tests, thus alleviating the multiple testing problem. We demonstrate that our method is able to reliably suppress false discoveries, while it is still very sensitive in discovering synchronous activity. Since we exploit high-speed computational techniques from frequent item set mining (FIM for the tests, our method is also computationally efficient.

    Aouiche, Kamel; Gruenwald, Le

    2008-01-01

    With the wide development of databases in general and data warehouses in particular, it is important to reduce the tasks that a database administrator must perform manually. The aim of auto-administrative systems is to administrate and adapt themselves automatically without loss (or even with a gain) in performance. The idea of using data mining techniques to extract useful knowledge for administration from the data themselves has existed for some years. However, little research has been achieved. This idea nevertheless remains a very promising approach, notably in the field of data warehousing, where queries are very heterogeneous and cannot be interpreted easily. The aim of this study is to search for a way of extracting useful knowledge from stored data themselves to automatically apply performance optimization techniques, and more particularly indexing techniques. We have designed a tool that extracts frequent itemsets from a given workload to compute an index configuration that helps optimizing data acce...

    Full Text Available Signature based NIDS are efficient at detecting attacks for what they are prepared for. This makes an intruderto focus on the new evasion technique to remain undetected. Emergence of new evasion technique may cause NIDS to fail. Unfortunately, most of these techniques are based on network protocols ambiguities, so NIDS designers must take them into account when updating their tools. This paper presents a framework for evading network intrusion detection system and detection over NIDS using frequent element pattern matching. The core of the framework is to model the NIDS using Adaboost algorithm that allows the understanding of how the NIDS classifies network data. We look for some way of evading the NIDS detection by changing some of the fields of the packets. We use publicly available dataset (KDD-99 for showing the proof of our concept. For real time evasion detection NIDS is build with Apriori algorithm to analyze NIDS robustness with high detection rate accuracy

  17. A SYSTEMATIC APPROACH AND ALGORITHM FOR FREQUENT DATA ITEMSETS

    Directory of Open Access Journals (Sweden)

    Vidushi Singhal

    2012-12-01

    Full Text Available The research in data mining is developing fast and efficient algorithm to derive knowledge from huge databases. There are several data mining algorithms available to solve diverse data mining problems. They are mainly classified as Associations, Classifications, Sequential Patterns and Clustering. Apriori is one of the most important algorithms used in Rule Association Mining. In this paper, we discuss the limitations of the Existing Apriori algorithm and then propose an enhancement for improving its efficiency. The drawbacks of the existing system may produce a larger number of candidate item sets and scan the database many times. The proposed algorithm is based on the reverse scan of a given database. If certain conditions are satisfied, the proposed algorithm can greatly reduce the scanning times required for the discovery of candidate itemsets. Therefore, much time and space has been saved while searching frequent itemsets.

  18. New techniques for mining frequent patterns in unordered trees.

    Zhang, Sen; Du, Zhihui; Wang, Jason T L

    2015-06-01

    We consider a new tree mining problem that aims to discover restrictedly embedded subtree patterns from a set of rooted labeled unordered trees. We study the properties of a canonical form of unordered trees, and develop new Apriori-based techniques to generate all candidate subtrees level by level through two efficient rightmost expansion operations: 1) pairwise joining and 2) leg attachment. Next, we show that restrictedly embedded subtree detection can be achieved by calculating the restricted edit distance between a candidate subtree and a data tree. These techniques are then integrated into an efficient algorithm, named frequent restrictedly embedded subtree miner (FRESTM), to solve the tree mining problem at hand. The correctness of the FRESTM algorithm is proved and the time and space complexities of the algorithm are discussed. Experimental results on synthetic and real-world data demonstrate the effectiveness of the proposed approach. PMID:25137740

  19. Frequently Asked Questions in Fire Probabilistic Safety Assessment

    International Nuclear Information System (INIS)

    The FAQs(Frequently Asked Questions) in the Fire Probabilistic Safety Assessment(FPSA) are the issues occurred during performing the engineering evaluation based on NFPA-805. In this report, the background and resolutions are reviewed and described for 17 FAQs related to FPSA among 57 FAQs. The current FAQs related to FPSA are the issues concerning to NUREG/CR-6850, and are almost resolved but for the some FAQ, the current resolutions would be changed depending on the results of the future or on-going research. Among FAQs related to FPSA, best estimate approaches are suggested concerning to the conservative method of NUREG/CR-6850. If these best estimate solutions are used in the FPSA of nuclear power plants, realistic evaluation results of fire risk would be obtained

O objetivo do caso é servir de oportunidade para os alunos vivenciarem uma decisão de investimentos por meio do lucro econômico. Uma análise superficial certamente levará a decisão equivocada. Levando-se todos os aspectos do caso em consideração, chegar-se-á a uma solução que pode surpreender alguns alunos, uma vez que a empresa melhor gerida não será a melhor oportunidade de investimento. Também se pode aproveitar o caso para discutir a superficialidade da adoção do EBITDA como métrica de gestão comparativamente a uma métrica de valor agregado (lucro econômico - a melhor solução também não é aquela que gera o maior aumento em EBITDA. O caso pode ser usado em disciplinas de finanças (finanças corporativas ou avaliação de empresas em cursos de graduação, pós-graduação ou especialização.

    Full Text Available Objectives: To compare the level of conjunctival changes using conjunctival impression cytology in wearers of frequent replacement hydrogel (FRHL and frequent replacement silicone hydrogel contact lens FRSHL. Materials and Methods: Forty-two contact lens users who were seen at the Cornea and Contact Lens Unit, Department of Ophthalmology, Dokuz Eylül University were evaluated in this study. The first group consisted of wearers of FRHL used for minimum one year and maximum five years. The second group consisted of wearers who used FRSHL for minimum one year and maximum 5 years. Twenty healthy individuals with no contact lens history were included in the control group. Conjunctival impression cytology was applied to all contact lens users and the control group in order to evaluate the conjunctival changes, and the results of impression cytology were graded by the Nelson’s method. Results: In the comparison of the groups according to impression cytology scoring, there was no difference between the users of FRHL and FRSHL. Similar amounts of squamous metaplasia and goblet cell loss were encountered in both groups. Nonetheless, impression cytology grading was significantly lower in the control group than in the other two groups. Conclusion: In conclusion, the use of FRHL and FRSHL for over a year causes some histological changes in the conjunctiva such as squamous metaplasia and goblet cell loss eventually leading to dry eye symptoms. However, no differences were determined between FRHL and FRSHL users with regard to severity of conjunctival changes. (Turk J Ophthalmol 2014; 44: 47-52

    The aim of this study was to investigate the risk factors of smartphone addiction in high school students.A total of 880 adolescents were recruited from a vocational high school in Taiwan in January 2014 to complete a set of questionnaires, including the 10-item Smartphone Addiction Inventory, Chen Internet Addiction Scale, and a survey of content and patterns of personal smartphone use. Of those recruited, 689 students (646 male) aged 14 to 21 and who owned a smartphone completed the questionnaire. Multiple linear regression models were used to determine the variables associated with smartphone addiction.Smartphone gaming and frequent smartphone use were associated with smartphone addiction. Furthermore, both the smartphone gaming-predominant and gaming with multiple-applications groups showed a similar association with smartphone addiction. Gender, duration of owning a smartphone, and substance use were not associated with smartphone addiction.Our findings suggest that smartphone use patterns should be part of specific measures to prevent and intervene in cases of excessive smartphone use.

    Full Text Available Data mining services require accurate input data for their results to be meaningful, but privacy concerns may influence users to provide spurious information. In order to preserve the privacy of the client in data mining process, a variety of techniques based on random perturbation of data records have been proposed recently. We focus on an improved distortion process that tries to enhance the accuracy by selectively modifying the list of items. The normal distortion procedure does not provide the flexibility of tuning the probability parameters for balancing privacy and accuracy parameters, and each item's presence/absence is modified with an equal probability. In improved distortion technique, frequent one item-sets, and nonfrequent one item-sets are modified with a different probabilities controlled by two probability parameters fp, nfp respectively. The owner of the data has a flexibility to tune these two probability parameters (fp and nfp based on his/her requirement for privacy and accuracy. The experiments conducted on real time datasets confirmed that there is a significant increase in the accuracy at a very marginal cost in privacy.

  5. Evidence and Implications of Frequent Fires in Ancient Shrub Tundra

    Understanding feedbacks between terrestrial and atmospheric systems is vital for predicting the consequences of global change, particularly in the rapidly changing Arctic. Fire is a key process in this context, but the consequences of altered fire regimes in tundra ecosystems are rarely considered, largely because tundra fires occur infrequently on the modern landscape. We present paleoecological data that indicate frequent tundra fires in northcentral Alaska between 14,000 and 10,000 years ago. Charcoal and pollen from lake sediments reveal that ancient birchdominated shrub tundra burned as often as modern boreal forests in the region, every 144 years on average (+/- 90 s.d.; n = 44). Although paleoclimate interpretations and data from modern tundra fires suggest that increased burning was aided by low effective moisture, vegetation cover clearly played a critical role in facilitating the paleo-fires by creating an abundance of fine fuels. These records suggest that greater fire activity will likely accompany temperature-related increases in shrub-dominated tundra predicted for the 21st century and beyond. Increased tundra burning will have broad impacts on physical and biological systems as well as land-atmosphere interactions in the Arctic, including the potential to release stored organic carbon to the atmosphere.

    The purpose of this work is to determine the most frequent short sequences in non-coding DNA. They may play a role in maintaining the structure and function of eukaryotic chromosomes. We present a simple method for the detection and analysis of such sequences in several genomes, including Arabidopsis thaliana, Caenorhabditis elegans, Drosophila melanogaster and Homo sapiens. We also study two chromosomes of man and mouse with a length similar to the whole genomes of the other species. We provide a list of the most common sequences of 9-14 bases in each genome. As expected, they are present in human Alu sequences. Our programs may also give a graph and a list of their position in the genome. Detection of clusters is also possible. In most cases, these sequences contain few alternating regions. Their intrinsic structure and their influence on nucleosome formation are not known. In particular, we have found new features of short sequences in C. elegans, which are distributed in heterogeneous clusters. They appear as punctuation marks in the chromosomes. Such clusters are not found in either A. thaliana or D. melanogaster. We discuss the possibility that they play a role in centromere function and homolog recognition in meiosis. PMID:19966278

    Oesophageal adenocarcinoma (EAC) incidence is rapidly increasing in Western countries. A better understanding of EAC underpins efforts to improve early detection and treatment outcomes. While large EAC exome sequencing efforts to date have found recurrent loss-of-function mutations, oncogenic driving events have been underrepresented. Here we use a combination of whole-genome sequencing (WGS) and single-nucleotide polymorphism-array profiling to show that genomic catastrophes are frequent in EAC, with almost a third (32%, n=40/123) undergoing chromothriptic events. WGS of 22 EAC cases show that catastrophes may lead to oncogene amplification through chromothripsis-derived double-minute chromosome formation (MYC and MDM2) or breakage-fusion-bridge (KRAS, MDM2 and RFC3). Telomere shortening is more prominent in EACs bearing localized complex rearrangements. Mutational signature analysis also confirms that extreme genomic instability in EAC can be driven by somatic BRCA2 mutations. These findings suggest that genomic catastrophes have a significant role in the malignant transformation of EAC. PMID:25351503

  8. Learning from failure in health care: frequent opportunities, pervasive barriers.

    Edmondson, A C

    2004-12-01

    The notion that hospitals and medical practices should learn from failures, both their own and others', has obvious appeal. Yet, healthcare organisations that systematically and effectively learn from the failures that occur in the care delivery process, especially from small mistakes and problems rather than from consequential adverse events, are rare. This article explores pervasive barriers embedded in healthcare's organisational systems that make shared or organisational learning from failure difficult and then recommends strategies for overcoming these barriers to learning from failure, emphasising the critical role of leadership. Firstly, leaders must create a compelling vision that motivates and communicates urgency for change; secondly, leaders must work to create an environment of psychological safety that fosters open reporting, active questioning, and frequent sharing of insights and concerns; and thirdly, case study research on one hospital's organisational learning initiative suggests that leaders can empower and support team learning throughout their organisations as a way of identifying, analysing, and removing hazards that threaten patient safety.

    Full Text Available CONTEXTO: Pouco se sabe sobre os mecanismos neurais precoces da leitura. Crianças com doenças do espectro do autismo, em raras ocasiões, apresentam avançadas habilidades de leitura. Apesar de suas sérias dificuldades na expressão e recepção da linguagem, essas crianças podem identificar palavras impressas tão jovens quanto aos 18 meses de idade sem nenhuma instrução explícita. RELATO DE CASO: Relatamos aqui um caso de uma criança de seis anos com história de autismo e que embora apresentasse dificuldades na comunicação, começou a ler aos três anos. Em seguida, discutimos algumas teorias sobre essa associação. CONCLUSÃO: Deficiências no desenvolvimento da linguagem e na comunicação são critérios definidores do autismo; já a hiperlexia, apesar de incomum, quando presente deve ser levada em conta para o diagnóstico. Seus mecanismos ainda são pouco compreendidos, mas diversos estudos feitos associados a outros que estão em andamento poderão elucidar melhor esse sintoma.BACKGROUND: Little is known about the early neural mechanisms of the reading ability. Children with autism spectrum, in rare occasions, present advanced reading abilities. In spite of their severe difficulties in language reception and expression, those children can identify words printed as young as for the 18 months of age without any explicit instruction. CASE REPORT: We report a case of a six year-old child with history of autism who, in spite of severe difficulties in communication, began to read at the age of three. We discuss some theories supporting this association. CONCLUSION: Deficiencies in the development of language and communication are definition criteria for autism. Hyperlexia is uncommon, but when present should be taken into account for the diagnosis. The underlying mechanisms are not completely understood and there is a limited number of studies that in addition to other studies in progress, will help to ellucidate the neurobiology

  12. Dosimetric properties of CaSO4: Dy thermoluminescent material

    International Nuclear Information System (INIS)

    The new ICRP regulations about radiological protection allows the different groups to study new high sensitivity thermoluminescent materials for dosimetric applications (personal and environmental). Different concentrations of Dy as dopant in the thermoluminescent material CaSO4 have been studied. The concentration usually encountered in bibliography for the CaSO4 is 0.1%. Our group have chosen the 1% Dy concentration due to its high sensitivity, the ratio for the CaSO4: Dy (1%) over the CaSO4: Dy (0.1%) is close to 3. The results obtained for the habitual set of tests (homogeneity, reproducibility, detection threshold, energy response and fading) reveals CaSO4: Dy (1%) as an excellent dosimetric material. We also present the good behavior of the CaSO4: Dy (0.1%) as a material for a retrospective dosimetry. (Author)

    With the exception of human immunodeficiency virus (HIV), which emerged in humans after cross-species transmissions of simian immunodeficiency viruses from nonhuman primates, immunodeficiency viruses of the family Lentiviridae represent species-specific viruses that rarely cross species barriers to infect new hosts. Among the Felidae, numerous immunodeficiency-like lentiviruses have been documented, but only a few cross-species transmissions have been recorded, and these have not been perpetuated in the recipient species. Lentivirus seroprevalence was determined for 79 bobcats (Lynx rufus) and 31 pumas (Puma concolor) from well-defined populations in Southern California. Partial genomic sequences were subsequently obtained from 18 and 12 seropositive bobcats and pumas, respectively. Genotypes were analyzed for phylogenic relatedness and genotypic composition among the study set and archived feline lentivirus sequences. This investigation of feline immunodeficiency virus infection in bobcats and pumas of Southern California provides evidence that cross-species infection has occurred frequently among these animals. The data suggest that transmission has occurred in multiple locations and are most consistent with the spread of the virus from bobcats to pumas. Although the ultimate causes remain unknown, these transmission events may occur as a result of puma predation on bobcats, a situation similar to that which fostered transmission of HIV to humans, and likely represent the emergence of a lentivirus with relaxed barriers to cross-species transmission. This unusual observation provides a valuable opportunity to evaluate the ecological, behavioral, and molecular conditions that favor repeated transmissions and persistence of lentivirus between species.

  15. [Adherence to chronic medication: also a frequent problem in Belgium!].

    Medication adherence in chronic conditions such as asthma, type 2 diabetes, heart failure, HIV and cancer appears to be a frequent problem. However, the literature on adherence in patients who use inhaled corticosteroids (ICS), oral hypoglycemic agents, drugs for heart failure, antiretrovirals or oral chemotherapy, contains little or no relevant data for Belgium. In the context of a Master thesis in Pharmaceutical care at KU Leuven, a quantitative study was performed to determine the prevalence of adherence to chronic medication in Belgium. This retrospective, cross-sectional study used a database containing refill data of a regional pharmacists' association (KLAV). Out of the 603 pharmacies affiliated with this association, all 50 pharmacies where HIV medication was delivered, were selected. Dispensing data from the selected pharmacies were collected from 01/07/2008 to 31/12/2009 for five pathologies, i.e.; asthma, type 2 diabetes, heart failure, HIV and cancer. Adherence (TT) was calculated with the Medication Refill Adherence (MRA) method. In order to determine whether there were associations between age, gender, drug class and adherence, Chi-square tests were used. Compared with the other patients, cancer patients were the most adherent in taking their drugs (median adherence rate = 88%). In addition, this was the only group in which the median adherence rate was above the set limit of 80%. The patients who were prescribed inhaled corticosteroids were the least adherent (median adherence rate = 38%). More than 50% of patients with asthma/COPD, heart failure and diabetes were classified as "under-users". Furthermore, the results showed a significant association within asthma patients between gender and adherence. In asthma, type 2 diabetes, heart failure and HIV patients there was a significant relationship between age and adherence and drug class and adherence. As the current study has some limitations, the results should be handled with caution. Nevertheless

  16. Frequent underwater volcanism in the central Aegean Sea

    2012-04-01

    The extinction of the Minoan culture in the mid second millennium BCE is a well known consequence of the Plinian eruption of Thera volcano (Santorini Island). Santorini is a member of the South Aegean arc forming a chain from the Gulf of Saronikos (Susaki, Egina, Poros, Methana) at West, to an area close to the Anatolian coast at East (Kos, Nisyros and minor islands), through the central part (Milos and Santorini island groups). Underwater volcanic activity was manifested historically only once. During 1649-1650 CE the Kolumbo underwater volcano evolved about 8 km northeast of Santorini. As a consequence of this eruption volcanic ash covered the entire Aegean area and a hazardous tsunami was triggered. Here we show by means of reflection seismic and magnetic data that underwater volcanism occurred more frequently in the central Aegean Sea than previously assumed. Seismic data show that Kolumbo constitutes of five vertically stacked cones of pyroclastic sediment plus at least four smaller cones on the flank of the volcano. The formation of Kolumbo started synchronous with Santorini Island. The entire volume of the Kolumbo pyroclastic cones is estimated to more than 15 cubic-kilometers. Several small-scale cones have been detected in the Anyhdros Basin some km north-east of Kolumbo, being previously interpreted as mud volcanoes by other authors. However, the similarity of seismic and magnetic signatures of these cones and Kolumbo strongly suggest that these cones were also created by underwater volcanism. Volcanic cones, Kolumbo and Santorini are situated along a NE-SW striking graben system that evolved during five extensional tectonic pulses in the Pliocene.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: O uso de ultrassom para guiar a punção em bloqueios de nervos periféricos tem-se tornado cada vez mais frequente. Com a menor probabilidade de promover lesões vasculares, o ultrassom torna-se uma ferramenta interessante na realização de bloqueios periféricos, especialmente nos pacientes em uso de anticoagulantes ou com distúrbios da coagulação. O objetivo foi relatar dois casos em que se realizaram os bloqueios isquiático e femoral guiados por ultrassom em pacientes anticoagulados. RELATO DOS CASOS: No primeiro caso, a cirurgia realizada consistiu na amputação de antepé esquerdo devido a necrose e sinais de infecção e, no segundo caso, em limpeza cirúrgica de joelho esquerdo. Os pacientes apr esentavam distúrbios de coagulação com atividade de protrombina e tempo de tromboplastina ativado acima dos valores da normalidade. Ambos os pacientes foram submetidos a bloqueio femoral e isquiático guiados por ultrassom, evoluindo sem alteração motora ou sensitiva nos territórios desses nervos e sem hematoma no local da punção. CONCLUSÕES: A anticoagulação impõe certas restrições à aplicação das técnicas anestésicas regionais clássicas. Com o avanço dos equipamentos e métodos de ultrassom, hoje é possível identificar com alta precisão estruturas vasculares e neurais. Isso possibilita que a punção guiada por ultrassom seja mais precisa, tanto para atingir a área de interesse como para minimizar os riscos de lesão vascular acidental. Até o presente, não se recomenda a realização de bloqueio periférico em pacientes anticoagulados ou portadores de coagulopatias. Entretanto, considerando que há poucos relatos sobre bloqueios regionais com ultrassom em situações de coagulopatias, a segurança de tal técnica nessas condições ainda não foi estabelecida.JUSTIFICATIVA Y OBJETIVOS: El uso del ultrasonido para guiar la punción en bloqueos de nervios periféricos se ha convertido

Atualmente, com o uso dos equipamentos de proteção individual, medidas de higiene pessoal e lavagem dos uniformes de trabalho, sua incidência diminuiu. Apesar de não ser uma doença rara, é pouco relatada na literatura, principalmente na nacional. Seu tratamento é lento e para a resolução das lesões, requer o afastamento do trabalhador de suas atividades laborativasElaioconiosis is a work-related acneiform dermatosis which affects the exposed skin of individuals working with oils or greases. Its incidence has decreased with the introduction of personal protective equipment, personal hygiene measures and the cleaning of work clothes. Although not a rare disease, elaioconiosis is seldom reported in the literature, particularly in Brazil. Sufferers need to take time off work to proceed with the prolonged treatment to resolve the lesions caused by this condition

    Full Text Available Introduction:The purpose of this study was to determine if differences could be detected in the presentation patterns and admission rates among frequent emergency department users (FEDU of an urban emergency department over a 10-year period.Methods: This was an IRB approved, retrospective review of all patients who presented to the ED 5 or more times for 3 distinct time periods: “year 0” 11/98-10/99, “year 5” 11/03–10/04, and “year 10” 11/08–10/9. FEDU were grouped into those with 5–9, 10–14, 15–19, and ≥ 20 visits per year. Variables analyzed included number of visits, disposition, and insurance status. We performed comparisons using Kolmogorov-Smirnov and chi-square tests. A P < 0.05 was considered significant.Results: We found a a 66% increase in FEDU patients over the decade studied, with a significant increase in both the number of FEDU in each visit frequency category over the 3 time periods (P < 0.0001, as well as the total number of visits by each group of FEDU (P < 0.0001. The proportion of FEDU visits for the 5–9 group resulting in admission increased from 25.9% to 29% from year 0 to year 10 (P < 0.001, but not for the other visit groups. In comparing admission rates between FEDU groups, the admission rate for the 5–9 group was significantly higher than the ≥ 20 group for the year 5 time period (P < 0.001 and the year 10 time period (P < 0.001 and showed a similar trend, but not significant, at year 0 (P = 0.052. The overall hospital admission rate for emergency patients over the same time span remained stable at 22-24%. The overall proportion of uninsured FEDU was stable over the decade studied, while the uninsured rate for the overall ED population for the same time periods increased.Conclusion: The results demonstrate the FEDU population is not a homogeneous group of patients. Increased attention to differences among FEDU groups is necessary in order to plan more effective interventions. [West J Emerg

    Full Text Available Abstract Background Worldwide, acute leukemia is the most common type of childhood cancer. It is particularly common in the Hispanic populations residing in the United States, Costa Rica, and Mexico City. The objective of this study was to determine the incidence of acute leukemia in children who were diagnosed and treated in public hospitals in Mexico City. Methods Included in this study were those children, under 15 years of age and residents of Mexico City, who were diagnosed in 2006 and 2007 with leukemia, as determined by using the International Classification of Childhood Cancer. The average annual incidence rates (AAIR, and the standardized average annual incidence rates (SAAIR per million children were calculated. We calculated crude, age- and sex-specific incidence rates and adjusted for age by the direct method with the world population as standard. We determined if there were a correlation between the incidence of acute leukemias in the various boroughs of Mexico City and either the number of agricultural hectares, the average number of persons per household, or the municipal human development index for Mexico (used as a reference of socio-economic level. Results Although a total of 610 new cases of leukemia were registered during 2006-2007, only 228 fit the criteria for inclusion in this study. The overall SAAIR was 57.6 per million children (95% CI, 46.9-68.3; acute lymphoblastic leukemia (ALL was the most frequent type of leukemia, constituting 85.1% of the cases (SAAIR: 49.5 per million, followed by acute myeloblastic leukemia at 12.3% (SAAIR: 6.9 per million, and chronic myeloid leukemia at 1.7% (SAAIR: 0.9 per million. The 1-4 years age group had the highest SAAIR for ALL (77.7 per million. For cases of ALL, 73.2% had precursor B-cell immunophenotype (SAAIR: 35.8 per million and 12.4% had T-cell immunophenotype (SAAIR 6.3 per million. The peak ages for ALL were 2-6 years and 8-10 years.

    Full Text Available Abstract Background Asperger syndrome (AS is a neurodevelopmental disorder belonging to autism spectrum disorders with prevalence rate of 0,35% in school-age children. It has been most extensively studied in childhood while there is scarcity of reports concerning adulthood of AS subjects despite the lifelong nature of this syndrome. In children with Asperger syndrome the initiation and continuity of sleep is disturbed because of the neuropsychiatric deficits inherent of AS. It is probable that sleep difficulties are present in adulthood as well. Our hypothesis was that adults with AS suffer from difficulty in initiating and maintaining sleep and nonrestorative sleep (insomnia. Methods 20 AS without medication were compared with 10 healthy controls devoid of neuropsychiatric anamnesis. Clinical examination, blood test battery and head MRI excluded confounding somatic illnesses. Structured psychiatric interview for axis-I and axis-II disorders were given to both groups as well as Beck Depression Inventory and Wechsler adult intelligence scale, revised version. Sleep quality was assessed with sleep questionnaire, sleep diary during 6 consecutive days and description of possible sleep problems by the participants own words was requested. Results compared with controls and with normative values of good sleep, AS adults had frequent insomnia. In sleep questionnaire 90% (18/20, in sleep diary 75% (15/20 and in free description 85% (17/20 displayed insomnia. There was a substantial psychiatric comorbidity with only 4 AS subject devoid of other axis-I or axis-II disorders besides AS. Also these persons displayed insomnia. It can be noted that the distribution of psychiatric diagnoses in AS subjects was virtually similar to that found among patient with chronic insomnia. Conclusions the neuropsychiatric deficits inherent of AS predispose both to insomnia and to anxiety and mood disorders. Therefore a careful assessment of sleep quality should be an

    Full Text Available É relatado um caso de retinoblastoma de aparecimento tardio, com características pouco freqüentes, com o objetivo de melhorar o controle da afecção. Em 1993, SJMMF, nove meses, masculino, leucodermo, apresentou tumor na retina esquerda. O paciente tinha história familiar de retinoblastoma. A enucleação foi realizada, comprovando-se retinoblastoma. Os exames para estadiamento sistêmico foram normais. O olho direito evoluiu normal por dez anos. Em exame de rotina, foram constatadas três lesões de retinoblastoma na retina nasal. Foi feita termoterapia transpupilar, com laser de diodo de 810 nm. Após 30 dias, as lesões regrediram. Após 60 dias houve recidiva na borda da lesão, onde foi realizada crioterapia transescleral, com regressão do tumor por seis meses. Durante o controle, observaram-se condensações próximas à lesão tumoral atrófica (sementes vítreas. Foi feito braquiterapia com Iodo125, havendo desaparecimento das mesmas após 30 dias. Novas sementes surgiram três meses pós-braquiterapia, depositadas na superfície retiniana, sendo tratadas com crioterapia transescleral e termoterapia transpupilar, havendo regressão. O paciente evoluiu com nova semente vítrea após seis meses, a qual, após depositar-se na superfície da retina, foi tratada com termoterapia transpupilar. Está em seguimento há 38 meses desde o aparecimento do tumor bilateral, mantendo acuidade visual de 20/20 e exames clínicos normais. Considera-se importante este caso pela pouca freqüência de aparecimento da doença nesta idade. Julga-se necessário o alerta para os casos de retinoblastoma já considerados curados.A case of retinoblastoma with uncommon features is reported, aiming at improving follow-up. In 1993, SJMMF, 9-month-old white boy, presented a squint in the left eye. A retinal tumor was detected. The patient had a family history of retinoblastoma.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: A neuralgia do nervo trigêmeo é uma condição intensamente dolorosa, caracterizada por surtos de dor lancinante e súbita, tipo choque, com duração de poucos segundos a dois minutos e geralmente unilateral. Sua incidência anual é de cerca de 4,3 em 100.000 na população geral, tendo manifestação bilateral em apenas 3% desses casos. O objetivo deste artigo foi descrever um caso raro de neuralgia do trigêmeo primário bilateral. RELATO DO CASO: Paciente de 61 anos, maranhense, casada, do lar, com antecedente de hipertensão arterial e há seis anos com queixa de dor intensa em V2-V3 à esquerda, com duração de 5 a 10 segundos, em região lateral do nariz e mandibular, com piora ao falar, mastigar e com diminuição da temperatura. Já havia utilizado clorpromazina (3 mg a cada oito horas e carbamazepina (200 mg a cada oito horas durante seis meses sem alívio da dor. Ao exame físico apresentava alodinia térmica e mecânica em regiões de V2-V3. Estava em uso de gabapentina (1.200 mg ao dia com alívio parcial da dor. Foi então aumentada a gabapentina para 1500 mg ao dia e introduzida amitriptilina 12,5 mg à noite. Evoluiu com dor leve e esporádica com diminuição da intensidade da dor ao longo de 10 meses de tratamento, sendo reduzida progressivamente a gabapentina para 600 mg ao dia e mantida a amitriptilina 12,5 mg ao dia. Após um ano, começou a apresentar dor de característica semelhante em região mandibular à direita, tendo melhorado com aumento de gabapentina para 900 mg ao dia. Não apresentava exames alterados de tomografia ou ressonância magnética de encéfalo. CONCLUSÕES: A carbamazepina é o fármaco de primeira escolha para tratamento de neuralgia trigeminal, porém a gabapentina tem sido cada vez mais utilizada como primeira medida farmacológica ou em casos refratários à terapia convencional.JUSTIFICATIVA Y OBJETIVOS: La neuralgia del nervio trigémino es una condici

    Full Text Available O carcinoma da próstata é uma doença freqüente em idosos e em casos avançados pode invadir o reto, simulando um carcinoma primário deste órgão. Nestas situações, a maioria dos pacientes apresenta sintomas retais exuberantes e sintomas urinários leves ou ausentes. É relatado um caso de um paciente com diagnóstico de tumor de próstata localmente agressivo, concomitante a um tumor viloso retal, que foi diagnosticado e tratado erroneamente como um tumor primário do reto. Tal lesão, curiosamente, apresentava comportamento biológico compatível com câncer retal, inclusive com disseminação linfática típica desta doença. A incidência relatada de invasão do reto por tumores de próstata avançados varia entre 1 e 11% em diferentes séries. O aspecto do tumor de próstata com envolvimento retal traz dificuldades em diferenciá-lo de um tumor primário. Exames radiológicos e ou endoscópicos podem não esclarecer o diagnóstico, enquanto o exame histopatológico em ambos os tumores costuma revelar adenocarcinoma pouco diferenciado. A diferenciação diagnóstica entre estes dois tumores é essencial, uma vez que o tratamento é absolutamente diferente para as duas doenças. A alta incidência do carcinoma prostático o torna importante para que todos os médicos estejam atentos à possibilidade deste tumor invadir o reto e simular um tumor primário deste órgão.Prostate carcinoma is a frequent disease in the elderly and in advanced cases it can cause rectal invasion mimicking a primary rectal carcinoma. Most of patients present with significant rectal symptoms and mild to absent urinary tract symptoms. We report a case of a patient with a very aggressive locally invasive prostate carcinoma with a concomitant rectal villous tumor which was misdiagnosed and inadequately treated as a rectal cancer. The reported incidence of rectal invasion in advanced prostate cancer has varied between 1 to 11 per cent in different series. The

    Full Text Available TEMA: identificar as alterações morfofuncionais decorrentes de quinze anos de obstrução nasal total em um caso de sinéquia de palato mole e paredes faríngeas pós blastomicose. PROCEDIMENTOS: o trabalho foi baseado no estudo de caso de um adulto do gênero feminino, de 26 anos de idade, que chegou a um centro especializado em deformidades craniofaciais, com a queixa de não conseguir respirar pelo nariz. Sua dificuldade respiratória é decorrente de uma aderência total do palato mole com as paredes faríngeas, como sequela da blastomicose que teve no palato aos 11 anos de idade. RESULTADOS: na entrevista, a paciente relatou queixa de cefaléia, halitose, pouco rendimento físico, sonolência diurna e sono agitado durante a noite. Referiu também anosmia, mastigação lenta e engasgos frequentes. Durante a avaliação, observou-se respiração exclusivamente oral do tipo superior, mastigação bilateral alternada e lenta, deglutição adaptada e ressonância hiponasal de grau grave. Observou-se ainda face longa, perfil convexo, mandíbula retruída e olheiras. Os lábios da paciente encontravam-se entreabertos e ressecados, sendo o superior fino e o inferior evertido e avolumado e o palato duro apresenta-se atrésico, estreito e profundo. CONCLUSÃO: as características da paciente em questão são compatíveis com a Síndrome do Respirador Oral e pode-se supor que sejam consequências morfofuncionais de uma obstrução nasal total.BACKGROUND: to identify the consequences that arising from fifteen years of total nasal obstruction in a case of post blastomicose palato and pharynx's lesion.

    Full Text Available Los leiomiomas perianales son tumoraciones derivadas de células mesenquimales distribuidas por todo el cuerpo. Histológicamente se han clasificado en tres subtipos: vascular, no vascular y epiteloide. El subtipo vascular puede ser sólido, cavernoso o venoso. Los leiomiomas son raros en adultos, con incidencia de 0,1 %, generalmente se presentan entre la cuarta a sexta década de la vida con predominio en mujeres en caso de ser benignos. La forma de presentación más frecuente es un nódulo palpable, próximo al ano e indoloro. El diagnóstico se realiza según criterios histológicos e inmunohistoquímicos, además son útiles la ecografía endoanal y RMN. La exéresis es la primera opción terapéutica. Se presenta caso de paciente femenino de 41 años de edad, quien consulta por presentar nódulo palpable perianal derecho, con dolor a la palpación, de ocho meses de evolución, con valores normales de marcadores tumorales, el ultrasonido revela a nivel perianal derecho imagen sólida, hipocrómica (con tejido lineal fibroso, mide 4.82x 6.7x 6.87cm, la RMN muestra lesión ocupante de espacio en la misma ubicación, Doppler Color sin vascularización.

    Full Text Available Num estudo retrospectivo de 1.071 necropsias de bovinos, foram encontrados 20 casos de babesiose cerebral confirmados pelo exame de esfregaços do córtex telencefálico. A maioria desses casos ocorreu no verão, em bovinos adultos de raças européias ou suas cruzas. Além dos sinais clínicos neurológicos, observou-se hemoglobinúria, anorexia, febre, taquicardia, taquipnéia e queda na produção de leite. O hemograma realizado em cinco bovinos afetados revelou acentuada anemia regenerativa; em média, 20% dos eritrócitos estavam parasitados por Babesia bovis. Na necropsia de todos os casos, a substância cinzenta dos córtices telencefálico e cerebelar e dos núcleos da base era consistente e caracteristicamente róseo-cereja. Essa coloração devia-se ao seqüestro de eritrócitos nos capilares encefálicos. Nesses eritrócitos, podiam-se observar, tanto em esfregaços do córtex como em preparações histológicas do encéfalo, microorganismos com morfologia compatível com B. bovis. Outros achados de necropsia incluíam hemoglobinúria, rins vermelho-escuros, hepatoesplenomegalia, fígado vermelho-alaranjado, icterícia, hemorragias epicárdicas e endocárdicas e edema e congestão dos linfonodos mesentéricos.

    Purpose: To present the mammographic cases most commonly misinterpreted by the participants in the mammography self-test proposed by the Italian Society of Medical Radiology (SIRM) National Congress in Rimini, Italy, 2002, by analysing the findings responsible for errors, suggesting reasons for the errors, and assessing possible inadequacies in the format of the test. Materials and methods: The self-test was performed on the mammograms of 160 cases (32 positive and 128 negative for cancer as confirmed by histology). The mammograms had been taken in the four standard projections and placed on four multi-panel diaphanoscopes, each displaying a set of 40 cases comprising benign and malignant cases in equal proportions. The participants were given pre-printed forms on which to note down their diagnostic judgement. We evaluated a total of 134 fully-completed forms. Among these, we identified the 23 cases most frequently misread by over 15 participants in percentages varying between 40-90%. Of these cases, 10 were malignancies and 13 were negative mammograms. On review, we also assessed the diagnostic contribution of complementary investigations (not available the participants). The 134 fully-completed forms (all of the 40 cases) yielded a total of 5360 responses, 1180 of which (22.01%) were incorrect. Of these 823 out of the 4288 cases expected to be negative (19.2%) were false positive, and 357 out of the 1072 cases expected to be positive (33.3%) were false negative. As regards the 23 most frequently misread cases, these were 10/32 (31.25%) mammograms positive for malignancy and 13/128 (10.15%) negative mammograms or mammograms showing benign disease. The 10 malignancies included 7 infiltrating ductal carcinomas, 1 infiltrating cribriform carcinoma, 1 infiltrating tubular carcinoma, and 1 carcinoma in situ. The 13 cases of benign disease - as established by histology or long-term follow-up - mistaken for malignancies by the test participants were fibrocystic breast

    Full Text Available A carência da vitamina B12 em muitas situações manifesta-se também por alterações neuropsiquiátricas, sendo a mais comum a degeneração combinada subaguda da medula espinhal. No sistema nervoso central a repercussão maior é na mielina, sendo a degeneração esponjosa e a desmielinização difusa das colunas lateral e posterior da medula as mais típicas alterações patológicas. O mesmo ocorre nos hemisférios cerebrais, sendo que anormalidades nas imagens por ressonância magnética são esperadas. No entanto muito pouco tem sido relatado e a carência da cobalamina não figura habitualmente na lista de diagnósticos diferenciais de lesões desmielinizantes. Relatamos caso de anemia perniciosa com manifestações neurológicas em que a ressonância magnética mostrou alterações compatíveis com desmielinização do feixe piramidal, consequentes, possivelmente, à carência da vitamina B12. Discutimos os achados neuropatológicos da hipovitaminose. Sugerimos que a degeneração combinada subaguda da medula deve fazer parte do diagnóstico diferencial radiológico das lesões desmielinizantes no sistema nervoso central.

    Full Text Available apesar de muitos avanços no campo da educação especial, ainda há muito poucos trabalhos relativos ao tema das Altas Habilidades/Superdotação (AH/SD, particularmente no interior do Brasil. Neste artigo são apresentados resultados de uma pesquisa objetivando investigar a conjectura de que há bastante desconhecimento sobre este assunto nas licenciaturas da Universidade Federal de Pelotas (UFPel. Como estudo de caso, foram levantados dados com cerca de um terço dos estudantes dos cursos de Licenciatura em Matemática. Utilizou-se como instrumento de pesquisa um questionário que permitia avaliações quantitativas e qualitativas dos conhecimentos e concepções dos alunos acerca das AH/SD. Os resultados indicaram que a maioria deles não estudou o assunto e este não é abordado curricularmente no curso. Com isso, eles desconhecem a legislação pertinente e nem mesmo sabem que os termos "superdotação" e "altas habilidades" têm o mesmo significado. Como fruto da desinformação, as respostas deles continham diferentes concepções mitológicas segundo a literatura de referência. Apenas para exemplificar, a maioria vê os alunos com AH/SD como um grupo homogêneo e não imagina um superdotado apresentando baixo rendimento escolar.

    Full Text Available Meningoencefalite criptocócica é infecção causada por um fungo denominado Cryptococcus neoformans. Duas formas são conhecidas: variação gattii e neoformans. A infecção antes da puberdade é rara. Cerca de metade dos pacientes apresentam algum estado imunossupressivo. O papiledema está presente em um terço dos pacientes por ocasião do diagnóstico. Relatamos um caso de meningoencefalite por criptococose em paciente de oito anos de idade, sem relato de doenças prévias, que evoluiu com amaurose bilateral. O diagnóstico foi confirmado por detecção do C. neoformans, var. gattii. O paciente foi tratado com anfotericina B e dexametasona. Na literatura existem poucos relatos de perda visual permanente após meningite por criptococose. A existência de um protocolo para tratamento de pacientes com papiledema é um fator determinante para evitar a perda visual.Cryptococcal meningitis is caused by the yeast Cryptococcus neoformans. Two varieties are recognized: var. gattii and var. neoformans. It is usually associated with immunosuppressive states, particularly HIV infection. Cryptococcal infection of the central nervous system is uncommon in immunocompetent children and difficult to diagnose. Ocular complications are common. Optic disc swelling was found in 33%. The following report describes a case of meningitis caused by C. neoformans var. gattii in an 8 year-old immunocompetent child who developed optic atrophy. The patient was treated with amphotericin B associated with corticosteroids. Possible therapeutic strategies aimed at reducing visual loss in cryptococcal meningitis have great importance to avoid this important morbidity.

    Full Text Available O artigo traz um levantamento dos principais modelos de gerenciamento do portfólio de projetos (PPM e uma análise crítica para a construção do quadro teórico. Neste estudo, foram realizados quatro estudos de caso em diferentes setores, com o objetivo de identificar as principais práticas de PPM adotadas, o estágio de implementação e a relação entre as práticas e os resultados obtidos. Os principais resultados indicam que o PPM ainda é pouco presente nas organizações, e que a falta dele é um dos fatores que dificultam a implementação adequada das ações estratégicas definidas pelos executivos. O desdobramento das ações estratégicas em projetos e a delegação da responsabilidade pela execução dos projetos aos níveis inferiores, de forma desestruturada, promovem conflitos desnecessários, com perda de energia da organização.This article consists of a review of the literature on the main PPM models, in addition to a critical analysis to build a theoretical framework. Four case studies are presented of companies from different sectors, which aim to identify the main PPM practices adopted, their implementation stage and the relations between those practices and the benefits obtained. The main research results show that PPM is still rarely present in organizations. The lack of PPM may be one of the factors hampering the correct implementation of strategic actions defined by the executive team. The deployment of strategic actions in projects and the structureless delegation of responsibility for implementation to mid- level managers creates unnecessary conflicts, with a consequential loss of an organization’s energy.

A pesar de estos avances, la mortalidad hospitalaria sigue siendo muy elevada. Nuestro objetivo fue analizar las características de los pacientes con endocarditis infecciosa activa y su relación con la mortalidad hospitalaria a lo largo de 16 años. Se realizó un registro prospectivo entre 1994 y 2010 de pacientes ingresados con endocarditis. Se analizaron características clínicas, evolución y tratamiento y se registraron los eventos intrahospitalarios. Ingresaron 152 pacientes, 64.5% varones, edad 45 ± 16 años, las causas más frecuentes de cardiopatía de base fueron: congénita 32 (21% y reumática 20 (13.2%. Los motivos de internación fueron síndrome febril 116 (76.3% e insuficiencia cardíaca 61 (40.1%.

O interesse desta publicação reside no fato de se tratar de uma raridade clínica com poucos casos descritos na literatura. Paciente do sexo feminino com 89 anos recorre ao serviço de urgência (SU após queda referindo dor intensa e incapacidade de mobilização de ambos os ombros. Ao exame objetivo apresentava sinais clínicos suspeitos de luxação glenoumeral anterior bilateral confirmados por radiografia. Ambas as luxações foram reduzidas no SU pela técnica de Milch modificada, com sucesso. Quando existe uma força simétrica e síncrona sobre os ombros e estes se apresentarem dolorosos e com limite funcional significativo, a suspeita de luxação glenoumeral bilateral, embora rara, é um diagnóstico diferencial a ter em conta.Bilateral anterior glenohumeral dislocation is a rare occurrence. We present a case of bilateral anterior glenohumeral dislocation caused by a fall. The interest in publishing this case is that this is a clinical rarity with few cases reported in the literature. An 89-year-old female patient was brought to the emergency department after a fall, complaining of intense pain in both shoulders and inability to move them. Objective examination showed clinical signs giving the suspicion of bilateral anterior glenohumeral dislocation, which was confirmed by x-ray imaging. Both dislocations were successfully reduced in the emergency department using the modified Milch technique. When a synchronous and symmetrical force has acted on both shoulders and these are painful with significant functional limitation, the suspicion of bilateral glenohumeral dislocation is a differential diagnosis to be considered, even though it is rare.

    Full Text Available Electroconvulsive therapy is known to be effective in the treatment of mood disorders, more specifically for depression and mania. Although a large body of evidence confirms the efficacy of electroconvulsive therapy in the treatment of mania, few prospective studies have been done to assess its effectiveness in treatment-resistant manic episodes. These case reports describe the initial results of a study that is being conducted to evaluate the efficacy of Electroconvulsive therapy among treatment-resistant bipolar patients. METHODS: Three manic patients (according to DSM-IV criteria who were considered treatment-resistant underwent a series of 12 bilateral Electroconvulsive therapy sessions. Before the treatment and then weekly, they were evaluated with the following rating scales: Young Mania Rating Scale, Hamilton Rating Scale for Depression, Brief Psychiatric Rating Scale, and Clinical Global Impressions-Bipolar Version. RESULTS: The 3 patients showed a satisfactory response to Electroconvulsive therapy, although some differences in the course of response were observed. CONCLUSION: These case reports suggest that Electroconvulsive therapy needs further evaluation for the treatment of resistant bipolar patients.A Eletroconvulsoterapia é uma alternativa reconhecidamente eficaz no tratamento dos transtornos do humor.

A biópsia dos gastrocnêmius direito e esquerdo revelou presença de um cisticerco além de hipertrofia das fibras musculares e infiltrado inflamatório. A revisão da literatura demonstra que apenas 12 casos de miopatia pseudo-hipertrófica causada por cisticercos foram relatados e que a incidência é duas vezes maior no sexo masculino do que no feminino. Em cerca de metade dos casos há história de epilepsia. Dor e fraqueza muscular discretas são frequentes. Em geral a pseudo-hipertrofia ocorre nas cinturas escapular e pélvica simultaneamente. Miotonia é achado raro e nódulos subcutâneos estão presentes na maioria dos pacientes. Nosso paciente difere dos outros relatados na literatura por apresentar pseudo-hipertrofia restrita às pernas, principalmente à esquerda, com eletromiografia revelando potenciais de unidades motoras gigantes. A patogênese desta condição é discutida e o diagnóstico diferencial deve ser feito com distrofia muscular pseudo-hipertrófica, triquinose, miotonia congênita, hipotireoidismo, amiloidose e a forma juvenil da glicogenose do tipo I (doença de Pompe.

    Full Text Available El diseño de casos cruzados es un diseño epidemiológico observacional propuesto por Maclure en 1991 para valorar si alguna exposición intermitente o inusual ha desencadenado un evento agudo a muy corto plazo. En este trabajo se presentan los fundamentos de los diseños de casos cruzados, con sus aplicaciones y limitaciones. El diseño de casos cruzados se basa en seleccionar sólo sujetos caso. Para calcular el riesgo relativo se compara la exposición durante el periodo de tiempo previo al evento (periodo caso con la exposición del mismo sujeto en uno o varios periodos control. Este método únicamente es adecuado cuando las exposiciones son cambiantes en el tiempo, con efectos a corto plazo, y el efecto es agudo. Para exposiciones en que no existe tendencia, el planteamiento unidireccional es el más frecuente, y consiste en seleccionar uno o varios periodos control previos al momento caso. Cuando la exposición tiene una tendencia temporal (por ejemplo las de contaminación atmosférica, el planteamiento unidireccional proporciona estimaciones sesgadas, por lo que se utilizan diseños de casos cruzados bidireccionales, que seleccionan periodos de tiempo control anteriores y posteriores al del evento. Es un método que cuenta con una creciente utilización en amplios campos: desencadenantes de accidentes de tráfico, laborales y domésticos, o de infarto agudo de miocardio, contaminación atmosférica y salud, farmacoepidemiología, etc. Para el análisis de datos, generalmente se pueden considerar los diseños de casos cruzados como estudios de casos y controles emparejados, por lo que se aplica regresión logística condicional. Finalmente, en este trabajo se analizan ejemplos prácticos de diferentes aplicaciones del diseño de casos cruzados.Case-crossover analysis is an observational epidemiological design that was proposed by Maclure in 1991 to assess whether a given intermittent or unusual exposure may have triggered an immediate

    Full Text Available O abscesso pulmonar é uma lesão necrótica geralmente devida a germes piogênicos. A fisioterapia respiratória (FR é indicada, porém há poucos relatos na literatura, não havendo consenso quanto ao uso e às técnicas de FR para esse caso. O objetivo deste estudo de dois casos foi verificar a segurança e efetividade da FR no tratamento do abcesso pulmonar. O caso 1 foi um paciente de 30 anos, internado; a terapia consistiu em posicioná-lo em Trendelenburg semi-lateral direito para ventral por 30 minutos, três vezes ao dia, com saída de grande quantidade de secreção. Após 5 dias, o radiograma de tórax demonstrou redução de 90% do nível hidroaéreo, verificando-se o esvaziamento completo do abscesso após 14 dias de internação. O caso 2 foi uma paciente de 28 anos igualmente com diagnóstico de abscesso pulmonar, também tratada com drenagem postural, nos mesmos posicionamento e freqüência que o caso 1, sendo drenada grande quantidade de secreção amarelada e fluida. Após 7 dias de tratamento evidenciou-se redução importante do nível líquido do abscesso pulmonar. Conclui-se que a drenagem postural isoladamente é uma técnica de fisioterapia efetiva e segura no tratamento do abcesso pulmonar.Lung abscess is a necrotic lesion mostly caused by pyogenic germs. Chest physical therapy (CPT is indicated, but there are few studies available and no consensus on CPT use and techniques for theses cases. The purpose of this study was to assess safety and effectiveness of postural drainage in treating lung abscess in two cases. Patient 1, male, 30 years old, was laid in Trendelenburg, in semi-lateral to ventral decubitus for 30 minutes, three times a day. After five days of therapy, X-ray showed a 90% decrease of sputum, and on the 14th day full drainage was achieved. Case 2 was a female patient, 28 years old, treated at the same position and frequency as case 1. After seven days of therapy, exams showed a great decrease of pus from

    Full Text Available La comparsa di neoplasie maligne è un evento frequente nei soggetti HIV positivi; si calcola infatti che circa il 25% di tali soggetti sviluppi una neoplasia maligna durante il corso dell’infezione. La maggioranza dei tumori insorgenti nei pazienti HIV positivi è rappresentata dal Sarcoma di Kaposi, dai Linfomi non Hodgkin e dai carcinomi della regione ano-genitale; un’aumentata incidenza appare presente anche per altre neoplasie maligne, quali il carcinoma basocellulare cutaneo, il Morbo di Hodking, il leiomiosarcoma del bambino. Inoltre, sporadicamente differenti tipi di tumori sono stati descritti in soggetti HIV positivi; il significato di queste associazioni tuttavia non è chiaro. In questo lavoro viene presentato un caso di teratoma del mediastino occorso in un paziente HIV positivo maschio di 37 anni. La causa dell’infezione da HIV è rimasta sconosciuta; al momento della diagnosi il valore assoluto di CD4 è risultato essere di 27/mmc. Il paziente è giunto a morte per la comparsa di un tamponamento cardiaco intrattabile riferibile alla progressione della patologia neoplastica. Anche per questo caso non è possibile definire con esattezza il significato della coesistenza tra infezione da HIV e neoplasia mediastinica; è comunque da sottolineare la assoluta rarità dell’associazione osservata.

En la metodología se combinan técnicas cualitativas, como la entrevista semiestructurada, y técnicas cuantitativas como un cuestionario “Ad hoc”. Se hizo un análisis documental y de contenido de los documentos expedidos por el Ministerio de Educación Nacional y la IE. Se aplicó la técnica del análisis de regresión simple para revisar el comportamiento de las variables independientes en este caso gratuidad y las variables dependientes como son cobertura, matrícula y deserción que permitiera realizar un contraste de los alcances y efectos de la gratuidad en la IE objeto de estudio. Por último, se realizó una triangulación con el fin de unir las diferentes técnicas para que nos arrojaran los resultados de esta investigación que en este caso indicaron que: i. La gratuidad se aplica conforme a los lineamientos del decreto 4807 de 2011; ii. Los lineamientos para la implementación y el seguimiento a la gratuidad no se comunican a los padres de familia; iii. Los docentes no tienen claridad sobre la destinación específica de los rubros de calidad; iv. La deserción no tiene una relación directa con la política de gratuidad y la gratuidad no tiene relación directa con la reducción de la tasa de deserción; v. La IE debe mejorar el sistema de comunicación con los padres; vi. La gratuidad está más relacionada con el acceso que con la calidad de los aprendizajes.

  18. Top Down Approach to find Maximal Frequent Item Sets using Subset Creation

    2012-10-01

    Full Text Available Association rule has been an area of active research in the field of knowledge discovery. Data mining researchers had improved upon the quality of association rule mining for business development by incorporating influential factors like value (utility, quantity of items sold (weight and more for the mining of association patterns. In this paper, we propose an efficient approach to find maximal frequent item set first. Most of the algorithms in literature used to find minimal frequent item first, then with the help of minimal frequent item sets derive the maximal frequent item sets. These methods consume more time to find maximal frequent item sets. To overcome this problem, we propose a navel approach to find maximal frequent item set directly using the concepts of subsets. The proposed method is found to be efficient in finding maximal frequent item sets.

    Full Text Available O trabalho apresenta um panorama atual da inovação no setor sucroalcooleiro pernambucano, cujo objetivo foi melhor entender as interações das empresas com as universidades e institutos públicos de pesquisa que têm promovido alguma inovação no setor. Adicionalmente, testou-se a hipótese, através do estudo de caso, de que o segmento supracitado preservou traços de sua história que legaram uma postura de setor pouco inovativo e dependente de proteção governamental. Parte de pesquisa mais ampla, o presente trabalho resulta de estudo de caso em que foram entrevistados agentes envolvidos com a interação U-E em usinas de açúcar, na instituição patronal e em instituições de pesquisa em Pernambuco. O estudo permitiu verificar que a inovação nesse setor ocorre de forma distinta em cada um dos três diferentes segmentos em que está subdividido: agricultura, indústria e transporte e mecanização. Na área agrícola, as empresas introduzem inovações que, no entanto, são desenvolvidas por instituições públicas de pesquisa existentes no estado, como a Ridesa e o Cetene, para quem as usinas e os pequenos produtores transferem esforços em P&D. Na área industrial e na de transporte e mecanização, as inovações são introduzidas por intermédio do sindicato patronal e de empresas de consultoria técnica que as importam de outras regiões ou países, enquanto o desenvolvimento de novos produtos não foi observado na indústria sucroalcooleira pernambucana. O foco das usinas locais é o mercado externo de açúcar por possuírem uma vantagem comparativa logística e contarem internamente com grande concorrência de produtores do Centro-Sul. Essa exportação do açúcar tem sido feita a granel, levando a crer que os produtores têm passado adiante parte importante da agregação de valor ao produto, deixando os procedimentos mais específicos, como criação de produtos finais diferenciados, para o importador e, por isso

Os autores relatam o caso de paciente de 73 anos, masculino, hipertenso, com antecedente de acidente vascular cerebral há 3 anos, com seqüela motora e sensitiva em membro superior direito, apresentando ao mapeamento dúplex e arteriografia oclusão total da carótida interna. Evoluiu após 2 anos com novos episódios de ataques isquêmicos transitórios de repetição. Submetido a novos exames de imagem para avaliação da circulação cerebral extra e intracraniana, evidenciou-se recanalização do vaso, com estenose severa. Foi realizada endarterectomia de carótida esquerda, sem intercorrências. Paciente evoluiu sem novos episódios após 1 mês de seguimento. Considerando a raridade do caso e a parca literatura sobre recanalização tardia de carótida, passível de reparo cirúrgico, optamos pela apresentação do caso enfocando a importância do acompanhamento de oclusões carotídeas.Late spontaneous recanalization of internal carotid artery is an unusual event that has received little attention. The authors report a case of a 73-year-old male patient, hypertensive, with previous history of cerebral vascular accident 3 years ago, with sensorimotor sequela in the right upper limb. Duplex scanning and arteriography showed total occlusion of the internal carotid artery. The patient progressed after 2 years with new episodes of recurrent transient ischemic attacks. When submitted to new imaging examinations to assess extra- and intracranial circulation, vessel recanalization was demonstrated, with severe stenosis. Left carotid endarterectomy was uneventfully performed. The patient progressed without new episodes after a 1-month follow-up. Considering the case rarity and the lack of literature on late carotid artery recanalization that can be surgically repaired, we decided to present this case focusing on the importance of following carotid

    Full Text Available Introducción: Existen diferentes formas clínicas de drepanocitosis, siendo la homocigosis la más grave. Es especialmente frecuente en la raza negra. Los actuales movimientos migratorios hacen que su manejo sea cada vez más frecuente en nuestro ámbito.  Presentamos dos casos de crisis vasooclusivas en niños afectos de drepanocitosis homocigota.
    Caso clínico 1: Paciente con drepanocitosis homocigota, que acude por cuadro febril, asociando dolor lumbar y en ambas rodillas, que no responde a analgesia oral. En la analítica, se objetivan anemia, leucocitosis con neutrofilia y elevación de los niveles de proteína C reactiva. Se instaura hidratación intravenosa abundante y tratamiento intravenoso con cefotaxima y morfina, con mejoría rápida.
    Caso clínico 2: Paciente con drepanocitosis homocigota, alérgico a cefalosporinas, consulta por fiebre y dolor óseo de 24 horas de evolución. Se realiza analítica, observándose anemia, leucocitosis y elevación de los reactantes de fase aguda. Se instaura cloruro mórfico y se cubre con clindamicina intravenosa. Ante la persistencia de la fiebre tras 48 horas, se solicitan pruebas de imagen, que resultan compatibles con síndrome torácico agudo. Se añade azitromicina oral, con buena evolución posterior.
    Conclusiones: La drepanocitosis es un problema emergente en nuestro medio, que obliga a conocer sus complicaciones, ya que su pronóstico depende de un diagnóstico y tratamiento precoz. Las complicaciones agudas más frecuentes son las crisis de dolor vaso-oclusivo óseo, que suelen requerir tratamiento analgésico agresivo. Otra complicación frecuente es el síndrome torácico agudo causante, en ocasiones, de hipoxemia refractaria. Introduction: There are different clinical forms of drepanocytosis, the most severe being homozygosis. It is especially frequent in the black race.

    Full Text Available Mining association rules in large database is one of most popular data mining techniques for business decision makers. Discovering frequent item set is the core process in association rule mining. Numerous algorithms are available in the literature to find frequent patterns. Apriori and FP-tree are the most common methods for finding frequent items. Apriori finds significant frequent items using candidate generation with more number of data base scans. FP-tree uses two database scans to find significant frequent items without using candidate generation. This proposed TR-FCTM (Transaction Reduction- Frequency Count Table Method discovers significant frequent items by generating full candidates once to form frequency count table with one database scan. Experimental results of TR-FCTM shows that this algorithm outperforms than Apriori and FP-tree.

    Full Text Available This retrospective cohort study provides a descriptive analysis of a population that frequently uses an urban emergency medical service (EMS and identifies factors that contribute to use among all frequent users. For purposes of this study we divided frequent users into the following groups: low- frequent users (4 EMS transports in 2012, medium-frequent users (5 to 6 EMS transports in 2012, high-frequent users (7 to 10 EMS transports in 2012 and super-frequent users (11 or more EMS transports in 2012. Overall, we identified 539 individuals as frequent users. For all groups of EMS frequent users (i.e. low, medium, high and super one or more hospital admissions, receiving a referral for follow-up care upon discharge, and having no insurance were found to be statistically significant with frequent EMS use (P<0.05. Within the diagnostic categories, 41.61% of super-frequent users had a diagnosis of “primarily substance abuse/misuse” and among low-frequent users a majority, 53.33%, were identified as having a “reoccurring (medical diagnosis.” Lastly, relative risk ratios for the highest group of users, super-frequent users, were 3.34 (95% CI [1.90-5.87] for obtaining at least one referral for follow-up care, 13.67 (95% CI [5.60-33.34] for having four or more hospital admissions and 5.95 (95% CI [1.80-19.63] for having a diagnoses of primarily substance abuse/misuse. Findings from this study demonstrate that among low- and medium-frequent users a majority of patients are using EMS for reoccurring medical conditions. This could potentially be avoided with better care management. In addition, this study adds to the current literature that illustrates a strong correlation between substance abuse/misuse and high/super-frequent EMS use. For the subgroup analysis among individuals 65 years of age and older, we did not find any of the independent variables included in our model to be statistically significant with frequent EMS use.

  8. Feasibility study of CaSO4:Eu, CaSO4:Eu,Ag and CaSO4:Eu,Ag(NP) as thermoluminescent dosimeters

    International Nuclear Information System (INIS)

    This work evaluates the dosimetric properties of crystals of CaSO4 doped with unusual elements, such as europium (Eu) and silver (Ag), including their nanoparticle forms, after the incorporation of glass or Teflon and compares them with well-known thermoluminescent dosimeters (TLD). X-ray diffraction analyses showed that samples of doped CaSO4 exhibit only a single phase corresponding to the crystal structure of anhydrite. Optical spectroscopy confirmed the presence of Eu3+ in the crystal matrix and a luminescent gain due the presence of silver nanoparticles. The composites showed thermoluminescent emission glow curves, with a single peak centered at approximately 200 °C for pellets with Teflon and at 230 °C for pellets with glass. The dosimeters based on calcium sulfate doped with europium and silver nanoparticles provided the most intense thermoluminescent (TL) emission of the composites studied. In comparison with commercial TLD, such as LiF:Mg,Ti and CaSO4:Dy, the CaSO4:Eu,Ag(NP)+glass produced in this work presented similar low detection limits and higher sensitivity. The new methods for the preparation of dosimeters and the incorporation of glass are shown to be viable because all of the samples presented a linear, reproducible and first order kinetic TL emission. - Highlights: • Thermoluminescent properties of CaSO4 doped with Eu, Ag and Ag nanoparticles were evaluated. • Crystals were grown using a production route based in the Yamashita method. • Glass or Teflon was incorporate to the crystals in order to obtain composites. • The TL responses of the composites are proportional to the dose absorbed. • The CaSO4:Eu,Ag(NP) + glass has potential to be used as a thermoluminescent dosimeter

    em pacientes com hiperplasia adrenal congênita virilizante. MÉTODOS: Trinta e quatro pacientes com idade média de 3,35 ± 2,5 anos com ambigüidade genital classificada de acordo com os estádios de Prader foram selecionados. O seguimento pós-operatório foi de 2 a 16 anos. O tamanho do clitóris variou de 1,9 a 5,0 cm; 28 pacientes tinham orifício único perineal e 6 tinham dois orifícios. A técnica cirúrgica incluiu clitorovaginoplastia em tempo único e foi realizada antes dos dois anos de idade em 18 pacientes. A clitoroplastia preservou a glande, a qual teve seu suprimento sanguíneo mantido em 97% dos casos pela mucosa do freio e no demais casos com a manutenção do feixe vasculo-nervoso dorsal. Duas técnicas foram utilizadas para a ampliação do seio urogenital: o retalho perineal em "Y-V" em 25 pacientes e a incisão longitudinal posterior em 8 pacientes. RESULTADOS: As complicações cirúrgicas ocorreram em 20,5% dos casos: sangramento, necrose da glande e estenose vaginal. Foram necessárias dilatações vaginais com moldes de acrílico no período pós puberal em 3 das pacientes com estenose, com bons resultados funcionais. CONCLUSÃO: As técnicas utilizadas seguidas pelas dilatações, permitiram bons resultados cosméticos e funcionais em 67% dos casos apresentando poucas complicações e evitando a necessidade de neovagina inclusive nos pacientes com inserção alta do intróito vaginal.

    Full Text Available La Anorexia Nervosa es un trastorno de alimentación que se define (etimológicamente como una "pérdida nerviosa del apetito". Se caracteriza por la actitud consciente, voluntaria y rotunda de los sujetos  de tener un exceso de peso que intentan modificar por vía de la inanición. A partir del estudio de casos, se propone la distinción entre una Anorexia Nervosa Estructural -aquella en la que predomina el conflicto intrapsíquico primario y arcaico, y que manifiesta una conducta aislada y retraída- y una Anorexia Nervosa Reactiva, aquella en la que predomina un conflicto intrafamiliar algo más posterior y, por lo tanto, una personalidad más abierta y compatible con el medio. Anorexia Nervosa is an Eating Disorder defined (etimoligacally as a "nervouse loss of apetite". It is characterized by a conscious, voluntary and categoric attitude of the sick patient to refrain from eating. He/she has a firm conviction of having excess weight which they try to modify by starvation. Through a case study, a distinction between two types of Anorexia Nervosa is proposed: a Structural Anorexia Nervosa -in which an intrapsyhic, primary, arcaic conflic prevails, leading to an isolated, withdrawal conduct- and a Reactive Anorexia Nervosa, in which a later intrafamilial conflict prevails leading, therefore, to a more open personality, compatible with the enviroment.

    Full Text Available Os autores relatam o caso de um homem de 38 anos de idade que apresentava uma hemiparesia direita nítida, sem afasia, datando de cerca de um mês. O déficit motor no dimídio direito se iniciara com violenta cefaléia, rebelde ao uso de analgésicos, mas que, pouco a pouco, cedeu completamente. O exame clínico não revelou qualquer causa capaz de explicar a hemiparesia. Liqüido cefaiorraquidiano e exame oftalmoscòpico inteiramente normais. As radiografias simples do crânio mostravam opacificação de consistência compacta no seio frontal e imagem aérea, volumosa, ocupando a maior parte do hemicrânio esquerdo. Os cortes planigráficos sagitais revelaram erosão da parede posterior e do assoalho do seio frontal, sem continuidade com a coleção de ar. Durante a operação foi verificada integridade da dura mater. Dias após a intervenção, a motricidade voluntária do hemicorpo direito já havia melhorado consideravelmente e, um mês após, o exame neurológico foi totalmente negativo. Tratava-se de osteoma ebùrneo. Após estudar os aspectos otorrinolaringológicos dos osteomas dos seios frontais, os autores consideram as suas eventuais complicações. Assim, se o tumor crescer para o lado, poderá invadir a órbita, causando exoftalmo, proptose e diplopia; expandindo-se para trás, poderá erosar a parede posterior do seio frontal, ocasionando pneumatocele extradural, como ocorreu no caso registrado neste trabalho; sucessivamente, poderá também perfurar a dura mater (pneumatocele subdural, invadir o tecido cerebral (pneumatocele intracerebral e mesmo se comunicar com o ventrículo lateral (pneumatocele ventricular. Essas coleções aéreas intracranianas (pneumocéfalos são eventualidades excepcionais em doença também rara. De fato, até 1941, haviam sido registrados 321 casos de osteomas, dos quais apenas 8 se complicaram de pneumocéfalo: 2 extradurais, 4 intracerebrais e 2 ventriculares. Por outro lado, essas complica

    Full Text Available JUSTIFICATIVA E OBJETIVOS: O edema pulmonar por pressão negativa após obstrução de via aérea é atualmente uma entidade bem descrita, porém pouco diagnosticada e com poucos casos relatados. O objetivo deste artigo foi relatar um caso de edema pulmonar por pressão negativa (EPPN após extubação traqueal com sucesso terapêutico, após uso de ventilação mecânica não-invasiva com pressão positiva. RELATO DO CASO: Paciente do sexo feminino, 22 anos, foi submetida à colecistectomia aberta. Os exames pré-operatórios encontravam-se sem alterações. Imediatamente após extubação a paciente apresentou dispnéia súbita e crepitações pulmonares. Foi iniciado tratamento para edema agudo de pulmão com oxigenoterapia sob máscara de Venturi, elevação do tórax e diurético. A paciente foi encaminhada a UTI devido a falha no tratamento. Ao chegar a UTI foi iniciada ventilação mecânica não-invasiva (VMNI com pressão de suporte (15 cmH2O e pressão expiratória final positiva (5 cmH2O com resolução dos sintomas. A paciente foi mantida em observação por mais 24 horas depois do evento com boas condições e recebeu alta para o quarto sem sintomas. CONCLUSÕES: O EPPN é uma entidade de difícil diagnóstico e deverá ser observada sempre que os pacientes evoluem com sinais e sintomas de insuficiência respiratória pós-extubação. Esta paciente se beneficiou de VMNI, mas caso haja falha terapêutica, a intubação traqueal e o suporte ventilatório mecânico invasivo deverão ser instituídos para melhor oxigenação dos pacientes.BACKGROUND AND OBJECTIVES: Negative pressure pulmonary edema after acute upper airway obstruction is a well-described event, thought infrequently diagnosed and reported.

    Dave Singh

    Full Text Available Patients with chronic obstructive pulmonary disease (COPD who are defined as frequent exacerbators suffer with 2 or more exacerbations every year. The molecular mechanisms responsible for this phenotype are poorly understood. We investigated gene expression profile patterns associated with frequent exacerbations in sputum and blood cells in a well-characterised cohort. Samples from subjects from the ECLIPSE COPD cohort were used; sputum and blood samples from 138 subjects were used for microarray gene expression analysis, while blood samples from 438 subjects were used for polymerase chain reaction (PCR testing. Using microarray, 150 genes were differentially expressed in blood (>±1.5 fold change, p≤0.01 between frequent compared to non-exacerbators. In sputum cells, only 6 genes were differentially expressed. The differentially regulated genes in blood included downregulation of those involved in lymphocyte signalling and upregulation of pro-apoptotic signalling genes. Multivariate analysis of the microarray data followed by confirmatory PCR analysis identified 3 genes that predicted frequent exacerbations; B3GNT, LAF4 and ARHGEF10. The sensitivity and specificity of these 3 genes to predict the frequent exacerbator phenotype was 88% and 33% respectively. There are alterations in systemic immune function associated with frequent exacerbations; down-regulation of lymphocyte function and a shift towards pro-apoptosis mechanisms are apparent in patients with frequent exacerbations.

  1. Study on the Development and Dosimetric Properties of New CaSO4:Dy TL Detectors Bonded by P-compounds for Gamma, Beta and Neutron Measurement

    International Nuclear Information System (INIS)

    A thermoluminescence dosimeter (TLD) has been generally accepted as the most accurate and reliable method of personal dosimetry because of its superior and long term stability comparing with other type dosimeter, such as Film Badge. Among many TL (thermoluminescence) materials investigated and suggested so far, the CaSO4:Dy TL material has been most widely used as a personal or environmental dosimeter because of its high sensitivity and low fading. A solid or crystalline form dosimeter is generally preferred for routine dosimetric applications since it has an advantage of handling convenience over the loose TL powder. For this reason, sintered TL pellets are usually used. However a difficulty is still in manufacturing the dosimeter in the form of sintered pellets in which the TL characteristics of original powder remain unchanged. It is not possible to make a solid dosimeter composed of 100 % pure CaSO4:Dy TL powder. One of the most frequent methods is mixing CaSO4:Dy TL powder with binding substances. A Teflon is a good binding material currently used because it does not change the TL characteristics of CaSO4:Dy TL powder. In the case of the Teflon pellet, due to the reduction of CaSO4:Dy powder content by 15 ∼ 20 wt% in TL pellets, the TL sensitivity of the Teflon pellet accordingly decreases, and moreover the re-usability of this Teflon pellet is not sufficient due to its color changing. To overcome this disadvantage, many researchers have prepared CaSO4:Dy TL pellets by mixing the powder with different binding substances. But even with these efforts, they could not significantly improve the TL intensity and other TL characteristics required for radiation dosimeter. In Korea, studies on the development of high sensitivity TL pellet using CaSO4:Dy TL material have been conducted in Korea Atomic Energy Research Institute (KAERI). This thesis presents the development of CaSO4:Dy TL pellet by bonding the TL powder with small amount of P-compounds designated as KCT

Assinala-se sua maior freqüência entre homens com mais de 50 anos, embora pacientes mais jovens possam ser acometidos, principalmente entre 15 e 29 anos. A distribuição segmentar dos tumores permite um diagnóstico diferencial, sendo a região torácica a sede mais freqüentes de sarcomas. O principal sintoma encontrado nos pacientes com reticulossarcoma foi a dor, do tipo radicular, que serve para diferenciar os tumores intra e extra-medulares, tendo sido de aparecimento precoce em 15 dos pacientes estudados, precedendo em muitos meses e até anos os demais sintomas. Classificou-se os tumores reticulohistiocitários epidurais do canal vertebral em três grupos, de acordo com seu aspecto tecidual e celular e, principalmente, com a presença e distribuição da reticulina. Relacionou-se o tempo de evolução desses tumores com seu aspecto histopatológico, chegando-se à conclusão que os tumores classificados no grupo III apresentam um período evolutivo maior que os demais, o que nos levou a pensar que crescem mais lentamente, apresentando, portanto, melhor prognóstico que os demais tipos, muito embora todos os tipos de reticulossarcomas possam apresentar um prognóstico mais favorável quando precocemente diagnosticados e tratados adequadamente.

    Full Text Available El turismo del vino tiene una concepción distinta en un destino masivo de sol y playa. En este caso el enoturismo convive con ese modelo turístico y es un producto complementario que favorece la diversificación en la oferta actual. El turismo del vino puede complementar la ya existente oferta turística, con lo que las regiones, turísticas y a la vez viníferas, podrían apoyarse en las experiencias y conocimiento del vino por parte del visitante y utilizarlas como hecho diferencial competitivo frente a otros destinos de sol y playa que no poseen esta particularidad. Con ello además se favorecerá el lanzamiento del producto turístico del vino, pues la demanda latente ya esta en las zonas turísticas que rodean el área vinícola. En este sentido, una vez que se descubren las motivaciones para acudir al destino Tenerife, se localiza un mercado sensible a la ruta del vino Tacoronte-Acentejo en el asentamiento turístico del Puerto de la Cruz (una de las principales zonas turísticas de Tenerife. Así, tras conocer los beneficios buscados por el visitante del Puerto de la Cruz, se ha contrastado la existencia de dos segmentos latentes que pueden ser atraídos hacia la oferta actual de la ruta del vino en Tacoronte-Acentejo, al verificar que persiguen, además del clima y el sol y playa (principales motivaciones para viajar al destino Tenerife, otros beneficios que son susceptibles de ser ofertados por la ruta del vino.

    2002-11-01

    Providing quality psychiatric emergency services is becoming more difficult as utilization rates soar, especially by individuals who are frequent visitors. To address this issue, a staff survey and analysis of admission patterns were conducted. Staff were more likely to believe that frequent visitors sought care because they had difficulty accessing alternative services, had basic needs unmet, were substance abusers, wanted inpatient admission, and were noncompliant with treatment plans. The 1999 temporal admission pattern documented that frequent visitors' admissions were higher during the first week of the month and inclement weather. Surprisingly, the infrequent visitors' admissions also were higher during the first week of the month. Together, these findings suggest that, in this urban location, frequent visitors are disadvantaged individuals lacking support and alternative treatment settings who use psychiatric emergency services to meet basic needs.

  13. A Frequent Closed Itemsets Lattice-based Approach for Mining Minimal Non-Redundant Association Rules

    CERN Document Server

    Vo, Bay

    2011-01-01

    There are many algorithms developed for improvement the time of mining frequent itemsets (FI) or frequent closed itemsets (FCI). However, the algorithms which deal with the time of generating association rules were not put in deep research. In reality, in case of a database containing many FI/FCI (from ten thousands up to millions), the time of generating association rules is much larger than that of mining FI/FCI. Therefore, this paper presents an application of frequent closed itemsets lattice (FCIL) for mining minimal non-redundant association rules (MNAR) to reduce a lot of time for generating rules. Firstly, we use CHARM-L for building FCIL. After that, based on FCIL, an algorithm for fast generating MNAR will be proposed. Experimental results show that the proposed algorithm is much faster than frequent itemsets lattice-based algorithm in the mining time.

    Exacerbations of chronic obstructive pulmonary disease (COPD) are important events that carry significant consequences for patients. Some patients experience frequent exacerbations, and are now recognized as a distinct clinical subgroup, the ‘frequent exacerbator’ phenotype. This is relatively stable over time, occurs across disease severity, and is associated with poorer health outcomes. These patients are therefore a priority for research and treatment.

    A single truncated chromosome fragment (TCF) in diploid cells undergoes frequent ectopic recombination during meiosis between markers located near the ends of the fragment. Tetrads produced by diploids with a single TCF show frequent loss of one of the two markers. This marker loss could result either from recombination of the TCF with one of the two copies of the chromosome from which it was derived or from ectopic recombination between the ends of the TCF. The former would result in shorten...

    2013-01-01

    Exacerbations of chronic obstructive pulmonary disease (COPD) are important events that carry significant consequences for patients. Some patients experience frequent exacerbations, and are now recognized as a distinct clinical subgroup, the 'frequent exacerbator' phenotype. This is relatively stable over time, occurs across disease severity, and is associated with poorer health outcomes. These patients are therefore a priority for research and treatment. The pathophysiology underlying the frequent exacerbator phenotype is complex, with increased airway and systemic inflammation, dynamic lung hyperinflation, changes in lower airway bacterial colonization and a possible increased susceptibility to viral infection. Frequent exacerbators are also at increased risk from comorbid extrapulmonary diseases including cardiovascular disease, gastroesophageal reflux, depression, osteoporosis and cognitive impairment. Overall these patients have poorer health status, accelerated forced expiratory volume over 1 s (FEV1) decline, worsened quality of life, and increased hospital admissions and mortality, contributing to increased exacerbation susceptibility and perpetuation of the frequent exacerbator phenotype. This review article sets out the definition and importance of the frequent exacerbator phenotype, with a detailed examination of its pathophysiology, impact and interaction with other comorbidities.

    2011-01-01

    Full Text Available Problem statement: Ffrequent patterns are patterns that appear in a data set frequently. Finding such frequent patterns plays an essential role in mining associations, correlations and many other interesting relationships among data. Approach: Most of the previous studies adopt an Apriorilike approach. For huge database it may need to generate a huge number of candidate sets. An interest solution is to design an approach that without generating candidate is able to mine frequent patterns. Results: An interesting method to frequent pattern mining without generating candidate pattern is called frequent-pattern growth, or simply FP-growth, which adopts a divide-and-conquer strategy as follows. However, for a large database, constructing a large tree in the memory is a time consuming task and increase the time of execution. In this study we introduce an algorithm to generate frequent patterns without generating a tree and therefore improve the time complexity and memory complexity as well. Our algorithm works based on prime factorization and is called Prime Factor Miner (PFM. Conclusion/Recommendations: This algorithm is able to achieve low memory order at O(1 which is significantly better than FP-growth.

    Full Text Available Document Clustering is one of the main themes in text mining. It refers to the process of grouping documents with similar contents or topics into clusters to improve both availability and reliability of text mining applications. Some of the recent algorithms address the problem of high dimensionality of the text by using frequent termsets for clustering. Although the drawbacks of the Apriori algorithm, it still the basic algorithm for mining frequent termsets. This paper presents an approach for Clustering Web Documents based on Hashing algorithm for mining Frequent Termsets (CWDHFT. It introduces an efficient Multi-Tire Hashing algorithm for mining Frequent Termsets (MTHFT instead of Apriori algorithm. The algorithm uses new methodology for generating frequent termsets by building the multi-tire hash table during the scanning process of documents only one time. To avoid hash collision, Multi Tire technique is utilized in this proposed hashing algorithm. Based on the generated frequent termset the documents are partitioned and the clustering occurs by grouping the partitions through the descriptive keywords. By using MTHFT algorithm, the scanning cost and computational cost is improved moreover the performance is considerably increased and increase up the clustering process. The CWDHFT approach improved accuracy, scalability and efficiency when compared with existing clustering algorithms like Bisecting K-means and FIHC.

    This study investigates the characteristics of frequent users of accident and emergency departments (AEDs) and recommends alternative medical services for such patients. Prominent demographic and clinical risk factors for individuals accessing seven AEDs located in the metropolitan area of Genoa, Italy are identified and analysed. A truncated count data model is implemented to establish the determinants of access, while a multinomial logistic regression is used to highlight potential differences among different user categories. According to previous studies, empirical findings suggest that despite the relevance of demographic drivers, vulnerability conditions (e.g. abuse of alcohol and drugs, chronic conditions, and psychological distress) are the main reasons behind frequent AED use; the analysis seems to confirm an association between AED frequent use and lower level of urgency. Since frequent and highly frequent users are found responsible for disproportionate resource absorption with respect to total amount of AED costs (they represent roughly 10% of the total number of patients, but contribute to more than 19% of the total annual AED cost), policies aiming to reduce frequent use of AEDs could bring significant savings in economic resources. Thus, efficient actions could be oriented toward extending primary care services outside AED and toward instituting local aid services specifically addressed to people under the influence of substances or in conditions of mental distress.

  17. Mining top-k frequent closed itemsets in data streams using sliding window

    International Nuclear Information System (INIS)

    Frequent itemset mining has become a popular research area in data mining community since the last few years. T here are two main technical hitches while finding frequent itemsets. First, to provide an appropriate minimum support value to start and user need to tune this minimum support value by running the algorithm again and again. Secondly, generated frequent itemsets are mostly numerous and as a result a number of association rules generated are also very large in numbers. Applications dealing with streaming environment need to process the data received at high rate, therefore, finding frequent itemsets in data streams becomes complex. In this paper, we present an algorithm to mine top-k frequent closed itemsets using sliding window approach from streaming data. We developed a single-pass algorithm to find frequent closed itemsets of length between user's defined minimum and maximum- length. To improve the performance of algorithm and to avoid rescanning of data, we have transformed data into bitmap based tree data structure. (author)

A presença de fatores de risco aterotrombóticos foi prevalente, em 48,22% dos pacientes com AVCI sendo que a hipertensão arterial sistêmica (HAS, nos casos de AVCH, foi a etiologia mais frequente. Em 32% dos casos não se pode determinar a sua causa. Embora a população jovem possua determinantes diferentes e geralmente deva ter uma investigação etiológica mais abrangente, no grupo estudado foram prevalentes os fatores de risco conhecidos e potencialmente controláveis, sugerindo que campanhas de prevenção e detecção precoce devam ser incentivados.We retrospectively analyzed the epidemiological features of 164 out-clinic patients with a first-onset stroke between 15 and 49 years old. Ischemic stroke occurred in 141 patients, hemorrhagic stroke in 16 patients, and venous thrombosis in 7 patients. Forty-eight percent of ischemic strokes were atherothrombotic, but no etiology was found in 32% of patients with ischemic stroke. Systemic arterial hypertension was the most frequent etiology in the hemorrhagic stroke group. The most frequent risk factors were systemic arterial hypertension, smoking, hypercholesterolemia, alcoholism and diabetes mellitus. Although stroke in young adults deserves some specific etiological investigation, we found that ordinary risk factors such as hypertension, tabacco use, hypercolesteremia and diabetes were prevalent in our population. It seems that prevention campaigns should be the target of our work.

MÉTODOS: em uma primeira etapa foram identificados os relatórios disponíveis contendo a descrição do estadiamento clínico inicial dos casos de câncer atendidos nos hospitais brasileiros. Considerando-se sua escassez e pouca representatividade, realizou-se uma segunda etapa na qual foi efetuada busca ativa de informações. Uma planilha foi enviada por via postal a todos (n=173 os Centros de Alta Complexidade em Oncologia (CACON cadastrados pelo Ministério da Saúde para atendimento ao SUS solicitando informações para o período compreendido entre 1995 e 2002. Para a análise estatística foi utilizado o programa "R". Os resultados são apresentados como percentuais e boxplots. RESULTADOS: na primeira etapa (1990-1994 foram identificadas informações de 18 hospitais, referentes a 7.458 pacientes com câncer de mama e 7.216 pacientes com câncer do colo do útero. A mediana de casos diagnosticados em estádio avançado (estádios III e IV foi de 52,6 e 56,8%, respectivamente. Na segunda etapa (1995-2002 foram obtidas informações de 89 hospitais e 7 serviços isolados de quimioterapia ou radioterapia, referentes a 43.442 casos de câncer de mama e 29.263 casos de câncer de colo do útero.

Presentamos 3 casos de anquilosis mandibular que en el examen preoperatorio presentaron dimorfismo mandibular, fusión de hueso maxilar y mandibular y anquilosis de la articulación témporomandibular. La ortopantografía y la Tomografía Axial Computerizada (TAC fueron muy útiles en la planificación de la cirugía. El tratamiento quirúrgico consistió en todos los casos en la resección del hueso anquilótico y la reconstrucción con injerto condrocostal en uno de los casos.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: Edema pulmonar por pressão negativa pós-obstrução de via aérea é atualmente uma entidade bem descrita, porém, provavelmente pouco diagnosticada e os casos pouco publicados. O objetivo deste relato é apresentar um caso de edema pulmonar por pressão negativa pós-obstrução de via aérea superior, cuja principal característica foi a assimetria do edema pulmonar, sendo muito mais acentuado no pulmão direito. RELATO DO CASO: Menino de 4 anos, 17 kg, estado físico ASA I, foi submetido a adenoamigdalectomia e cauterização de cornetos, sob anestesia geral com sevoflurano/óxido nitroso/O2. A cirurgia durou 1 hora e 30 minutos sem qualquer intercorrência. Com a superficialização da anestesia o paciente, ventilando espontaneamente, reagiu ao tubo traqueal, que foi retirado. Após isto, os esforços ventilatórios resultaram em retração da parede torácica, sem aparente movimento de ar, sendo impossível ventilá-lo com máscara facial, ocorrendo hipoxemia grave (SpO2 de 50%, necessitando ser reintubado. Neste momento foi verificado que o pulmão se encontrava mais duro e havia estertores bilateralmente, caracterizando edema pulmonar. Uma radiografia de tórax mostrou infiltrado pulmonar difuso bilateralmente, porém, com atelectasia do lobo superior direito, mostrando acentuada assimetria do edema pulmonar. O paciente teve que ser ventilado mecanicamente com PEEP durante 20 horas, quando foi extubado. Houve melhora progressiva do edema pulmonar, recebendo alta em 48 horas. CONCLUSÕES: O edema pulmonar por pressão negativa é uma entidade rara com alto grau de morbidade, pouco diagnosticada e exige do anestesiologista conhecimento atualizado e tratamento adequado. Costuma ser bilateral, raramente unilateral e excepcionalmente com expressiva assimetria como no nosso relato. A maioria dos casos é tratada com suporte ventilatório com PEEP ou CPAP, não necessitando de qualquer outra terapia. O prognóstico

    Full Text Available Sleep apnea has been recognized as a factor predisposing to atrial fibrillation recurrence and progression. The effect of other sleep-disturbing conditions on atrial fibrillation progression is not known. We sought to determine whether frequent periodic leg movement during sleep is a risk factor for progression of atrial fibrillation. In this retrospective study, patients with atrial fibrillation and a clinical suspicion of restless legs syndrome who were referred for polysomnography were divided into two groups based on severity of periodic leg movement during sleep: frequent (periodic movement index >35/h and infrequent (≤35/h. Progression of atrial fibrillation to persistent or permanent forms between the two groups was compared using Wilcoxon rank-sum test, chi-square tests and logistic regression analysis. Of 373 patients with atrial fibrillation (77% paroxysmal, 23% persistent, 108 (29% progressed to persistent or permanent atrial fibrillation during follow-up (median, 33 months; interquartile range, 16-50. Compared to patients with infrequent periodic leg movement during sleep (n=168, patients with frequent periodic leg movement during sleep (n=205 had a higher rate of atrial fibrillation progression (23% vs. 34%; p=0.01. Patients with frequent periodic leg movement during sleep were older and predominantly male; however, there were no significant differences at baseline in clinical factors that promote atrial fibrillation progression between both groups. On multivariate analysis, independent predictors of atrial fibrillation progression were persistent atrial fibrillation at baseline, female gender, hypertension and frequent periodic leg movement during sleep. In patients with frequent periodic leg movement during sleep, dopaminergic therapy for control of leg movements in patients with restless legs syndrome reduced risk of atrial fibrillation progression. Frequent leg movement during sleep in patients with restless legs syndrome is

A International Financial Reporting Interpretation 13 (IFRIC 13 trata da contabilização dos programas de fidelidade de clientes, amplamente utilizado pelo setor de transporte aéreo. As companhias aéreas têm influência considerável na economia, mas são poucos os estudos contábeis que focam os dados por elas gerados. Outrossim, o presente artigo tem por objetivo analisar o impacto da adoção da IFRIC 13 nas demonstrações contábeis das companhias aéreas presentes na Bolsa de Valores de São Paulo: Gol e TAM. Para isso foram utilizadas as informações anuais de 2009 e 2010. De tal modo, foi possível observar que, quanto à mensuração dos pontos de milhagem, ambas as empresas utilizavam anteriormente à norma o custo incremental, sendo que em 2010 houve a alteração para a contabilização com base na receita diferida, registrada ao valor justo, como sugerida pela IAS 18. Adicionalmente observou-se que em 2009 não houve antecipação da adoção da referida norma pelas empresas. Em 2010, com a obrigatoriedade de se contabilizar com base na IFRIC 13, as duas companhias apresentaram o consequente ajuste nos dados de 2009. Isso possibilitou concluir que as informações ajustadas destacaram a alteração da composição patrimonial, no resultado e em indicadores financeiros decorrente das novas regras.

  18. Differentially Private Frequent Sequence Mining via Sampling-based Candidate Pruning

    Science.gov (United States)

    Xu, Shengzhi; Cheng, Xiang; Li, Zhengyi; Xiong, Li

    2016-01-01

    In this paper, we study the problem of mining frequent sequences under the rigorous differential privacy model. We explore the possibility of designing a differentially private frequent sequence mining (FSM) algorithm which can achieve both high data utility and a high degree of privacy. We found, in differentially private FSM, the amount of required noise is proportionate to the number of candidate sequences. If we could effectively reduce the number of unpromising candidate sequences, the utility and privacy tradeoff can be significantly improved. To this end, by leveraging a sampling-based candidate pruning technique, we propose a novel differentially private FSM algorithm, which is referred to as PFS2. The core of our algorithm is to utilize sample databases to further prune the candidate sequences generated based on the downward closure property. In particular, we use the noisy local support of candidate sequences in the sample databases to estimate which sequences are potentially frequent. To improve the accuracy of such private estimations, a sequence shrinking method is proposed to enforce the length constraint on the sample databases. Moreover, to decrease the probability of misestimating frequent sequences as infrequent, a threshold relaxation method is proposed to relax the user-specified threshold for the sample databases. Through formal privacy analysis, we show that our PFS2 algorithm is ε-differentially private. Extensive experiments on real datasets illustrate that our PFS2 algorithm can privately find frequent sequences with high accuracy. PMID:26973430

    The present study informs understanding of customer segmentation strategies by extending Twedt's heavy-half propositions to include a segment of users that represent less than 2% of all households-consumers demonstrating extremely frequent behavior (EFB). Extremely frequent behavior (EFB) theory provides testable propositions relating to the observation that few (2%) consumers in many product and service categories constitute more than 25% of the frequency of product or service use. Using casino gambling as an example for testing EFB theory, an analysis of national survey data shows that extremely frequent casino gamblers do exist and that less than 2% of all casino gamblers are responsible for nearly 25% of all casino gambling usage. Approximately 14% of extremely frequent casino users have very low-household income, suggesting somewhat paradoxical consumption patterns (where do very low-income users find the money to gamble so frequently?). Understanding the differences light, heavy, and extreme users and non-users can help marketers and policymakers identify and exploit "blue ocean" opportunities (Kim and Mauborgne, Blue ocean strategy, Harvard Business School Press, Boston, 2005), for example, creating effective strategies to convert extreme users into non-users or non-users into new users.

    Full Text Available Fodor ha argumentado a favor de un par de tesis que pueden caracterizarse como constituyendo un dilema: Por un lado, si adoptamos una teoría funcional para los conceptos explicamos semánticamente los casos Frege pero caemos en el holismo semántico. Por otro lado, si adoptamos una teoría causal/informacional evitamos el holismo pero no explicamos los casos Frege semánticamente. Fodor (por ej, 1994, 1998 y 2008 intenta evitar la segunda parte del dilema argumentando que los casos de Frege pueden tener una explicación sintáctica y no semántica. En este trabajo intentaré ofrecer una salida alternativa al dilema fodoriano. Propondré una explicación semántica de los casos Frege que incorpora tanto elementos de una teoría causal como de una de rol funcional. Afirmaré que el contenido cognitivo o estrecho de un concepto (el tipo de contenido aparentemente exigido por los casos Frege es el conjunto de contenidos causales/informacionales de las representaciones que figuran en su rol funcional. Considero que individuar a las representaciones en los roles por medio de sus contenidos causales permite evitar el holismo (evitando el proceso de ramsificación típicamente empleado para individuar a los roles y que identificar el contenido cognitivo con contenidos causales/informacionales de las representaciones en los roles permite evitar el referencialismo de las propuestas causales (podemos distinguir sentido de referencia en términos causales.

    Full Text Available In this study, generating association rules with improved Apriori algorithm is proposed. Apriori is one of the most popular association rule mining algorithm that extracts frequent item sets from large databases. The traditional Apriori algorithm contains a major drawback. This algorithm wastes time in scanning the database to generate frequent item sets. The objective of any association rule mining algorithm is to generate association rules in a fast manner with great accuracy. In this study, a modification over the traditional Apriori algorithm is introduced. This improved Apriori algorithm searches frequent item sets from the large databases with less time. Experimental results shows that this improved Apriori algorithm reduces the scanning time as much as 67% and this algorithm is more efficient than the existing algorithm.

    Nightmares are relatively common sleep complaints that seem to be associated with affective distress. To date, few attempts have been made to link nightmares to the biological markers of the stress response, and the HPA response in particular. The present study examined the relationship between frequent nightmares and the cortisol awakening response (CAR) in a cross-sectional study of working women (N=188). Analysis revealed that those who reported frequent nightmares (N=13) showed a blunted CAR on a working day, compared to those who did not report nightmares. This result was independent of psychiatric symptoms, demographic variables, and lifestyle. Our preliminary findings suggest that decreased HPA reactivity might be a trait-like feature of women with frequent nightmares. PMID:25953663

    Square-wave jerks (SWJs) are small, involuntary saccades that disrupt steady fixation. We report the case of an astronaut (approximately 140 d on orbit) who showed frequent SWJs, especially postflight, but who showed no impairment of vision or decrement of postflight performance. These data support the view that SWJs do not impair vision because they are paired movements, consisting of a small saccade away from the fixation position followed, within 200 ms, by a corrective saccade that brings the eye back on target. Since many returning astronauts show a decrement of dynamic visual function during postflight locomotion, it seems possible that frequent SWJs improved this astronaut's visual function by providing postsaccadic enhancement of visual fixation, which aided postflight performance. Certainly, frequent SWJs did not impair performance in this astronaut, who had no other neurological disorder.

  5. Integrating Entropy and Closed Frequent Pattern Mining for Social Network Modelling and Analysis

    The recent increase in the explicitly available social networks has attracted the attention of the research community to investigate how it would be possible to benefit from such a powerful model in producing effective solutions for problems in other domains where the social network is implicit; we argue that social networks do exist around us but the key issue is how to realize and analyze them. This chapter presents a novel approach for constructing a social network model by an integrated framework that first preparing the data to be analyzed and then applies entropy and frequent closed patterns mining for network construction. For a given problem, we first prepare the data by identifying items and transactions, which arc the basic ingredients for frequent closed patterns mining. Items arc main objects in the problem and a transaction is a set of items that could exist together at one time (e.g., items purchased in one visit to the supermarket). Transactions could be analyzed to discover frequent closed patterns using any of the well-known techniques. Frequent closed patterns have the advantage that they successfully grab the inherent information content of the dataset and is applicable to a broader set of domains. Entropies of the frequent closed patterns arc used to keep the dimensionality of the feature vectors to a reasonable size; it is a kind of feature reduction process. Finally, we analyze the dynamic behavior of the constructed social network. Experiments were conducted on a synthetic dataset and on the Enron corpus email dataset. The results presented in the chapter show that social networks extracted from a feature set as frequent closed patterns successfully carry the community structure information. Moreover, for the Enron email dataset, we present an analysis to dynamically indicate the deviations from each user's individual and community profile. These indications of deviations can be very useful to identify unusual events.

    Full Text Available Abstract Background To describe the characteristics of emergency department (ED patients defined as frequent presenters (FP presenting to an Australian emergency department network and compare these with a cohort of non-frequent presenters (NFP. Method A retrospective chart review utilising an electronic emergency medicine patient medical record database was performed on patients presenting to Southern Health EDs from March 2009 to March 2010. Non-frequent presenters were defined as patients presenting less than 5 times and frequent presenters as presenting 8 or more times in the study period. Characteristics of both groups were described and compared. Results During the 12-month study period there were 540 FP patients with 4549 admissions and 73,089 NFP patients with 100,943 admissions. FP patients were slightly older with a significant increase in frequency of patients between the ages of 70 to 79 years and they were more likely to be divorced or separated than NFP patients. Frequent presenters to the emergency department were more likely to utilise the ambulance service to arrive at the hospital, or in the custody of police than NFP patients. FPs were more likely to be admitted to hospital, more likely to have an admission to a mental health bed than NFP patients and more likely to self-discharge from the emergency department while waiting for care. Conclusions There are major implications for the utilisation of limited ED resources by frequent presenters. By further understanding the characteristics of FP we may be able to address the specific health care needs of this population in more efficient and cost effective ways. Further research analysing the effectiveness of targeted multidisciplinary interventions aiming to reduce the frequency of ED attendances may be warranted.

    Full Text Available Sequential Pattern mining is the process of applying data mining techniques to asequential database for the purposes of discovering the correlation relationships that existamong an ordered list of events. The task of discovering frequent sequences ischallenging, because the algorithm needs to process a combinatorially explosive numberof possible sequences. Discovering hidden information from Web log data is called Webusage mining. One common usage in web applications is the mining of users’ accessbehaviour for the purpose of predicting and hence pre-fetching the web pages that theuser is likely to visit. The aim of discovering frequent Sequential patterns in Web log datais to obtain information about the access behaviour of the users.Finding Frequent Sequential Pattern (FSP is an important problem in web usagemining. In this paper, we explore a new frequent sequence pattern technique calledAWAPT (Adaptive Web Access Pattern Tree, for FSP mining. An AWAPT combinesSuffix tree and Prefix tree for efficient storage of all the sequences that contain a givenitem. It eliminates recursive reconstruction of intermediate WAP tree during the miningby assigning the binary codes to each node in the WAP Tree. Web access pattern tree(WAP-tree mining is a sequential pattern mining technique for web log accesssequences, which first stores the original web access sequence database(WASD on aprefix tree, similar to the frequent pattern tree (FP-tree for storing non-sequential data.WAP-tree algorithm then, mines the frequent sequences from the WAP-tree byrecursively re-constructing intermediate trees, starting with suffix sequences and endingwith prefix sequences. An attempt has been made to AWAPT approach for improvingefficiency. AWAPT totally eliminates the need to engage in numerous reconstructions ofintermediate WAP-trees during mining and considerably reduces execution time.

    This paper addresses an Integrated Framework for relational and hierarchical mining of Frequent Closed Pattern. Large data banks have created the necessity to formulate a system for effective retrieval of data patterns. The major issues that have to be dealt here are granularity of patterns, effectiveness of patterns and time taken for retrieval. Here we discuss Inter-related generalized self-organizing map (IGSOM) and relational attribute-oriented induction (RAOI), which are focused on pattern extraction along with CC-MINER, a hierarchical mining technique for exploring Frequent Closed Pattern from very dense data sets. We further provide implementation results for education data set and prostrate cancer data set.

    Background Comorbidities have a serious impact on the frequent severe acute exacerbations (AEs) in patients with COPD. Previous studies have used the Charlson comorbidity index to represent a conglomerate of comorbidities; however, the respective contribution of each coexisting disease to the frequent severe AEs remains unclear. Methods A retrospective, observational study was performed in 77 COPD patients who experienced severe AE between January 2012 and December 2014 and had at least 1-year follow-up period from the date of admission for severe AE. We explored the incidence of frequent severe AEs (≥2 severe AEs during 1-year period) in these patients and investigated COPD-related factors and comorbidities as potential risk factors of these exacerbations. Results Out of 77 patients, 61 patients (79.2%) had at least one comorbidity. During a 1-year follow-up period, 29 patients (37.7%) experienced frequent severe AEs, approximately two-thirds (n=19) of which occurred within the first 90 days after admission. Compared with patients not experiencing frequent severe AEs, these patients were more likely to have poor lung function and receive home oxygen therapy and long-term oral steroids. In multiple logistic regression analysis, coexisting asthma (adjusted odds ratio [OR] =4.02, 95% confidence interval [CI] =1.30–12.46, P=0.016), home oxygen therapy (adjusted OR =9.39, 95% CI =1.60–55.30, P=0.013), and C-reactive protein (adjusted OR =1.09, 95% CI =1.01–1.19, P=0.036) were associated with frequent severe AEs. In addition, poor lung function, as measured by forced expiratory volume in 1 second (adjusted OR =0.16, 95% CI =0.04–0.70, P=0.015), was inversely associated with early (ie, within 90 days of admission) frequent severe AEs. Conclusion Based on our study, among COPD-related comorbidities, coexisting asthma has a significant impact on the frequent severe AEs in COPD patients. PMID:27536097

    Full Text Available OBJECTIVE: To report the difficulties in managing a case of os odontoideum. METHODS: Female patient, 12 years old who developed a quadiparesis after minor cervical trauma in October 2005. In the emergency department a congenital cervical anomaly was identified. The patient was placed in a Stryker® frame and, few days later, in a halo bracing. After 3 months, an infection around the pins emerged and the halo vest had to be removed. A severe C1-2 instability persisted and a C1-C2 Gallie procedure was attempted. In the following weeks the bone disappeared and another procedure was attempted in June 2006 - C1 laminectomy and occiput-C3 fusion. In the following months the neurological status of the patient improved and a complete mass of occiput-C3 fusion was observed. RESULTS: We choose a posterior cervical arthrodesis of C1-C2 using the Gallie technique. Since the condition was not resolved we performed a second surgery, C1 laminectomy (determined by SAC of 8, 3 mm in MRI followed by posterior occiput-C3 fusion. In our case, until now, there is no evidence of axial decompensation, but a more prolonged follow-up is needed. CONCLUSIONS: The treatment of os odontoideum has many considerations but the essential that in the presence of instability and neurological deficit a solid fusion is achieved. In case of failure of posterior atlantoaxial wiring, the occiput-C2 or C3 fusion with rods seems to be an excellent option with a high rate of success, avoiding the need for additional support.OBJETIVO: Informe sobre las dificultades para tratar un caso de os odontoideum.

    2012-02-01

    Full Text Available JUSTIFICATIVA E OBJETIVOS: O hematoma subdural intracraniano é uma complicação rara após raquianestesia. O diagnóstico é muitas vezes difícil porque os sintomas iniciais são os mesmos da cefaleia pós-punção da dura-máter. O objetivo é relatar o caso de um hematoma subdural diag nosticado precocemente, após uma raquianestesia realizada com agulha de calibre fino e punção única. RELATO DO CASO: Paciente de 48 anos, ASA I, submetida a raquianestesia para cirurgia de correção de incontinência urinária. Foi realizada a raquianestesia com agulha 27G Quincke e punção única. A cirurgia foi sem intercorrências, e a paciente recebeu alta hospitalar. Após 48 horas da punção raquidiana, a paciente relatou cefaleia de início súbito, de forte intensidade, acometendo principalmente a região orbitária, mas também a região temporal, com melhora importante no decúbito dorsal e acompanhada de dois episódios de vômitos. Foi solicitada tomografia de crânio que revelou a presença de um hematoma subdural agudo frontotemporoparietal esquerdo. Foi indicado tratamento conservador com analgésicos, dexametasoma e hidantoína. Após 17 dias, apresentou quadro de cefaleia intensa, acompanhada de dormência e paresia do membro superior direito, e distúrbio da fala e comportamento. O hematoma foi drenado cirurgicamente. A paciente evoluiu bem sem sequelas. CONCLUSÕES: A cefaleia é a complicação mais frequente após raquianestesia e é considerada de evolução benigna. Faz com que diagnósticos potencialmente fatais, como o hematoma subdural, não sejam feitos em muitos casos, ou sejam tardios. Este caso descreve uma ocorrência rara, um hematoma subdural agudo após uma raquianestesia com agulha fina em uma paciente sem fatores de risco para sangramento

    Full Text Available Spatial Data Mining is based on correlation of spatial objects in space. Mining frequent pattern fromspatial databases systems has always remained a challenge for researchers. In the light of the first law ofgeography “everything is related to everything else but nearby things is more related than distant things”suggests that values taken from samples of spatial data near to each other tend to be more similar thanthose taken farther apart. This tendency is termed spatial autocorrelation or spatial dependence. It’snatural that most spatial data are not independent, they have high autocorrelation. In this paper, wepropose an enhancement of existing mining algorithm for efficiently mining frequent patterns for spatialobjects occurring in space such as a city is located near a river. The frequency of each spatial object inrelation to other object tends to determine multiple occurrence of the same object. We further enhancethe proposed approach by using a numerical method. This method uses a tree structure basedmethodology for mining frequent patterns considering the frequency of each object stored at each node ofthe tree. Experimental results suggest significant improvement in finding valid frequent patterns overexisting methods.

  2. The Role of Old-growth Forests in Frequent-fire Landscapes

    Directory of Open Access Journals (Sweden)

    2007-12-01

    Full Text Available Classic ecological concepts and forestry language regarding old growth are not well suited to frequent-fire landscapes. In frequent-fire, old-growth landscapes, there is a symbiotic relationship between the trees, the understory graminoids, and fire that results in a healthy ecosystem. Patches of old growth interspersed with younger growth and open, grassy areas provide a wide variety of habitats for animals, and have a higher level of biodiversity. Fire suppression is detrimental to these forests, and eventually destroys all old growth. The reintroduction of fire into degraded frequent-fire, old-growth forests, accompanied by appropriate thinning, can restore a balance to these ecosystems. Several areas require further research and study: 1 the ability of the understory to respond to restoration treatments, 2 the rate of ecosystem recovery following wildfires whose level of severity is beyond the historic or natural range of variation, 3 the effects of climate change, and 4 the role of the microbial community. In addition, it is important to recognize that much of our knowledge about these old-growth systems comes from a few frequent-fire forest types.

  4. GraMi: Generalized Frequent Pattern Mining in a Single Large Graph

    KAUST Repository

    Saeedy, Mohammed El

    2011-11-01

    Mining frequent subgraphs is an important operation on graphs. Most existing work assumes a database of many small graphs, but modern applications, such as social networks, citation graphs or protein-protein interaction in bioinformatics, are modeled as a single large graph. Interesting interactions in such applications may be transitive (e.g., friend of a friend). Existing methods, however, search for frequent isomorphic (i.e., exact match) subgraphs and cannot discover many useful patterns. In this paper the authors propose GRAMI, a framework that generalizes frequent subgraph mining in a large single graph. GRAMI discovers frequent patterns. A pattern is a graph where edges are generalized to distance-constrained paths. Depending on the definition of the distance function, many instantiations of the framework are possible. Both directed and undirected graphs, as well as multiple labels per vertex, are supported. The authors developed an efficient implementation of the framework that models the frequency resolution phase as a constraint satisfaction problem, in order to avoid the costly enumeration of all instances of each pattern in the graph. The authors also implemented CGRAMI, a version that supports structural and semantic constraints; and AGRAMI, an approximate version that supports very large graphs. The experiments on real data demonstrate that the authors framework is up to 3 orders of magnitude faster and discovers more interesting patterns than existing approaches.

    2014-01-01

    Mining frequent subgraphs is an important operation on graphs; it is defined as finding all subgraphs that appear frequently in a database according to a given frequency threshold. Most existing work assumes a database of many small graphs, but modern applications, such as social networks, citation graphs, or proteinprotein interactions in bioinformatics, are modeled as a single large graph. In this paper we present GRAMI, a novel framework for frequent subgraph mining in a single large graph. GRAMI undertakes a novel approach that only finds the minimal set of instances to satisfy the frequency threshold and avoids the costly enumeration of all instances required by previous approaches. We accompany our approach with a heuristic and optimizations that significantly improve performance. Additionally, we present an extension of GRAMI that mines frequent patterns. Compared to subgraphs, patterns offer a more powerful version of matching that captures transitive interactions between graph nodes (like friend of a friend) which are very common in modern applications. Finally, we present CGRAMI, a version supporting structural and semantic constraints, and AGRAMI, an approximate version producing results with no false positives. Our experiments on real data demonstrate that our framework is up to 2 orders of magnitude faster and discovers more interesting patterns than existing approaches. 2014 VLDB Endowment.

  6. Frequent users of emergency services: associated factors and reasons for seeking care

    Full Text Available Aim: to identify the profile of frequent users of emergency services, to verify the associated factors and to analyze the reasons for the frequent use of the services. METHOD: An explanatory sequential type mixed method was adopted. Quantitative data were collected from the electronic medical records, with a sample of 385 users attended four or more times in an emergency service, during the year 2011. Qualitative data were collected through semi-structured interviews with 18 users, intentionally selected from the results of the quantitative stage. Quantitative data were analyzed using descriptive and inferential statistics and qualitative data using thematic analysis. RESULTS: It was found that 42.9% were elderly, 84.9% had chronic diseases, 63.5% were classified as urgent, 42.1% stayed for more than 24 hours in the service and 46.5% were discharged. Scheduled follow-up appointment, risk classification, length of stay and outcome were factors associated with frequent use. The reasons for seeking the services were mainly related to the exacerbation of chronic diseases, to easier access and concentration of technology, to the bond, and to the scheduled appointments. CONCLUSIONS: The results contribute to comprehending the repeated use of emergency services and provide additional data to plan alternatives to reduce frequent use.

    2007-01-01

    Because data warehouse is frequently changing, incremental data leads to old knowledge which is mined formerly unavailable. In order to maintain the discovered knowledge and patterns dynamically, this study presents a novel algorithm updating for global frequent patterns-IPARUC. A rapid clustering method is introduced to divide database into n parts in IPARUC firstly, where the data are similar in the same part. Then, the nodes in the tree are adjusted dynamically in inserting process by "pruning and laying back" to keep the frequency descending order so that they can be shared to approaching optimization. Finally local frequent itemsets mined from each local dataset are merged into global frequent itemsets. The results of experimental study are very encouraging. It is obvious from experiment that IPARUC is more effective and efficient than other two contrastive methods. Furthermore, there is significant application potential to a prototype of Web log Analyzer in web usage mining that can help us to discover useful knowledge effectively, even help managers making decision.

    Dust storms in northern China strongly affect the living and health of people there and the dusts could travel a full circle of the globe in a short time. Historically, more frequent dust storms occurred during cool periods, particularly the Little Ice Age (LIA), generally attributed to the strengthened Siberian High. However, limited by chronological uncertainties in proxy records, this mechanism may not fully reveal the causes of dust storm frequency changes. Here we present a late Holocene dust record from the Qaidam Basin, where hydrological changes were previously reconstructed, and examine dust records from northern China, including the ones from historical documents. The records, being broadly consistent, indicate the onset of frequent dust storms at ~AD 1100. Further, peaked dust storm events occurred at episodes of high total solar irradiance or warm-dry conditions in source regions, superimposed on the high background of frequent dust storms within the cool LIA period. We thus suggest that besides strong wind activities, the centennial-scale dust storm events over the last 1000 years appear to be linked to the increased availability of dust source. With the anticipated global warming and deteriorating vegetation coverage, frequent occurrence of dust storms in northern China would be expected to persist.

  1. Association Rule Mining for Both Frequent and Infrequent Items Using Particle Swarm Optimization Algorithm

    Directory of Open Access Journals (Sweden)

    MIR MD. JAHANGIR KABIR

    2014-07-01

    Full Text Available In data mining research, generating frequent items from large databases is one of the important issues and the key factor for implementing association rule mining tasks. Mining infrequent items such as relationships among rare but expensive products is another demanding issue which have been shown in some recent studies. Therefore this study considers user assigned threshold values as a constraint which helps users mine those rules which are more interesting for them. In addition, in real world users may prefer to know relationships among frequent items along with infrequent ones. The particle swarm optimization algorithm is an important heuristic technique in recent years and this study uses this technique to mine association rules effectively. If this technique considers user defined threshold values, interesting association rules can be generated more efficiently. Therefore this study proposes a novel approach which includes using particle swarm optimization algorithm to mine association rules from databases. Our implementation of the search strategy includes bitmap representation of nodes in a lexicographic tree and from superset-subset relationship of the nodes it classifies frequent items along with infrequent itemsets. In addition, this approach avoids extra calculation overhead for generating frequent pattern trees and handling large memory which store the support values of candidate item sets. Our experimental results show that this approach efficiently mines association rules. It accesses a database to calculate a support value for fewer numbers of nodes to find frequent itemsets and from that it generates association rules, which dramatically reduces search time. The main aim of this proposed algorithm is to show how heuristic method works on real databases to find all the interesting association rules in an efficient way.

    Full Text Available Neurofibromatosis type 1 (NF1 can virtually affect any organ, presenting most frequently with "cafe au lait" spots and neurofibromas. Vasculopathy is a known complication of NF1, but cerebrovascular disease is rare. We report the case of a 51-year-old man admitted to the hospital with a history of stroke four months before admission. On physical examination, he presented various "cafe au lait" spots and cutaneous neurofibromas. Neurologic examination demonstrated right-sided facial paralysis, right-sided hemiplegia, and aphasia. Computed tomography scan of head showed hypodense areas in the basal ganglia and centrum semiovale. Radiographs of cranium and cervical spine showed basilar impression. Angiography revealed complete occlusion of both vertebral and left internal carotid arteries, and partial stenosis of the right internal carotid artery. A large network of collateral vessels was present (moyamoya syndrome. It is an uncommon case of occlusive cerebrovascular disease associated with NF1, since most cases described in the literature are in young people, and tend to spare the posterior cerebral circulation. Basilar impression associated with this case may be considered a pure coincidence, but rare cases of basilar impression and NF1 have been described.A neurofibromatose tipo 1 (NF1 pode acometer qualquer órgão mas as apresentações mais frequente são manchas café com leite e neurofibromas.

    Full Text Available Vinte e seis casos de cefaléia-em-salvas são estudados do ponto de vista clínico e terapêutico. Nos aspectos clínicos são ressaltados a dramaticidade deste tipo de cefaléia, o nítido predomínio no sexo masculino, a média de idade dos pacientes, a presença de manifestações associadas e os fatores desencadeantes das crises nos períodos suscetíveis. Do ponto de vista terapêutico três esquemas medicamentosos foram utilizados: maleato de metisergida, prednisona e associação de ambas as drogas. Em 88,3% dos casos um resultado significativo foi alcançado, traduzido por melhora ou abolição das crises.

    Este trabajo examina uno de los con- flictos legales más importantes relacionados con la censura y la regulación de internet. Originado en el año 2000, el caso Yahoo! representa un hecho paradigmático no sólo por el problema normativo entre dos países, Estados Unidos y Francia, sino porque saca a debate los aspectos más problemáticos de la protección de la libre expresión en los medios de comunicación. Visto desde el aspecto legal, el caso Yahoo! nos alerta ante la posibilidad de la aparic...

  13. The Properties of CaSO4: Mn Thermoluminescence Dosimeters

    International Nuclear Information System (INIS)

    The properties of the radio thermoluminescence of CaSO4:Mn, used for dosimetry of gamma and roentgen radiation, have been investigated. The light yield of the luminophore has been determined to 1.5 percent for 1 MeV gamma radiation. The dependence of the thermoluminescence light sum on the exposure, the exposure rate, and the exposure time can qualitatively be described by the first order process model, modified by a broad energy distribution of the electron trap depths. Some applications are discussed. The cheapness of the dosimeters, the convenient read-out, and the broad range of measurable exposures suggest that CaSO4:Mn can be a valuable complement to other dosimetry systems

    L’esposizione intrauterina all’alcol determina uno spettro di anomalie morfologiche e di deficit neuro-comportamentali, indicati con il termine “disturbo dello spettro fetale alcolico”. Si descrive il caso di un bambino di 13 mesi con esposizione intrauterina all’alcol, che presenta ritardo di crescita e microcefalia. Tutti gli esami diagnostici effettuati allo scopo di identificare una causa organica del ritardo di crescita hanno dato un risultato negativo. Pertanto, siamo orientati verso un...

    Full Text Available OBJETIVO: O objetivo deste estudo é o de identificar as diversas causas que nos obrigam a novo procedimento cirúrgico. Apesar de várias alterações técnicas como platinectomia total, platinectomia parcial, interposição óssea, fenestra na platina e o emprego de vários tipos de próteses, os problemas continuam a existir, talvez também pelo pouco treinamento feito pelos residentes nos Centros Universitários, onde o número de cirurgias estapedianas vem caindo ano a ano, o que leva à pouca experiência destes residentes em sua vida futura. FORMA DE ESTUDO: Avaliação Retrospectiva. MATERIAL E MÉTODO: Baseou-se em 74 casos de revisões de estapedectomia, realizadas em 68 pacientes, sendo 47 ouvidos submetidos à primeira revisão e 4 ouvidos submetidos à uma segunda revisão, todos operados anteriormente pelo autor, de uma população de 725 estapedectomias realizadas na clínica privada e 282 estapedectomias realizadas no Hospital Universitário Antônio Pedro (HUAP - Universidade Federal Fluminense/Niterói-RJ, de julho de 1980 a junho de 1999. Acrescentamos mais 21 casos operados de primeira revisão e de 2 casos operados de segunda revisão oriundos de outros serviços. RESULTADOS: Considerando todos os casos de revisões cirúrgicas realizadas, os ganhos auditivos obtidos foram os seguintes: em 78,3% dos pacientes os ganhos auditivos alcançados foram de até 20dB; em 10,8% dos pacientes de 20dB a 25dB; em 8,2% dos pacientes acima de 25dB, tendo ocorrido anacusia em 2,7% dos pacientes. A avaliação auditiva incluiu o limiar aéreo-ósseo de 250 a 8000Hz com a discriminação vocal e o SRT, sendo que nas freqüências de 500, 1000 e 2000Hz os limiares das vias aérea e óssea foram calculados através dos audiogramas realizados nos pré e pós-operatórios. Os resultados auditivos pós-operatórios dependem da afecção cirúrgica encontrada, principalmente pela presença ou ausência da bigorna e pela reobliteração óssea na

  18. Approximating Frequent Items in Asynchronous Data Stream over a Sliding Window

    DEFF Research Database (Denmark)

    In an asynchronous data stream, the data items may be out of order with respect to their original timestamps. This paper studies the space complexity required by a data structure to maintain such a data stream so that it can approximate the set of frequent items over a sliding time window...... with sufficient accuracy. Prior to our work, the best solution is given by Cormode et al. [1], who gave an O (1/ε log W log (εB/ log W) min {log W, 1/ε} log |U|)- space data structure that can approximate the frequent items within an ε error bound, where W and B are parameters of the sliding window, and U...

  19. Bit-Table Based Biclustering and Frequent Closed Itemset Mining in High-Dimensional Binary Data

    Full Text Available During the last decade various algorithms have been developed and proposed for discovering overlapping clusters in high-dimensional data. The two most prominent application fields in this research, proposed independently, are frequent itemset mining (developed for market basket data and biclustering (applied to gene expression data analysis. The common limitation of both methodologies is the limited applicability for very large binary data sets. In this paper we propose a novel and efficient method to find both frequent closed itemsets and biclusters in high-dimensional binary data. The method is based on simple but very powerful matrix and vector multiplication approaches that ensure that all patterns can be discovered in a fast manner. The proposed algorithm has been implemented in the commonly used MATLAB environment and freely available for researchers.
