College & Research Libraries, 77(1, 7-19. http://doi.org/10.5860/crl.77.1.7 Objective – To determine which metadata elements best facilitate discovery of digital collections. Design – Case study. Setting – A public research university serving over 32,000 graduate and undergraduate students in the Southwestern United States of America. Subjects – A sample of 22,559 keyword searches leading to the institution’s digital repository between August 1, 2013, and July 31, 2014. Methods – The author used Google Analytics to analyze 73,341 visits to the institution’s digital repository. He determined that 22,559 of these visits were due to keyword searches. Using Random Integer Generator, the author identified a random sample of 378 keyword searches. The author then matched the keywords with the Dublin Core and VRA Core metadata elements on the landing page in the digital repository to determine which metadata field had drawn the keyword searcher to that particular page. Many of these keywords matched to more than one metadata field, so the author also analyzed the metadata elements that generated unique keyword hits and those fields that were frequently matched together. Main Results – Title was the most matched metadata field with 279 matched keywords from searches. Description and Subject were also significant fields with 208 and 79 matches respectively. Slightly more than half of the results, 195 keywords, matched the institutional repository in one field only. Both Title and Description had significant match rates both independently and in conjunction with other elements, but Subject keywords were the sole match in only three of the sampled cases. Conclusion – The Dublin Core elements of Title, Description, and Subject were the most frequently matched fields in keyword

    NONE DECLARED. Keywords are the most important tools for Information retrieval. They are usually used for retrieval of articles based on contents of information reserved from printed and electronic resources. Retrieval of appropriate keywords from Medical Subject Headings (MeSH) can impact with exact, correctness and short time on information retrieval. Regarding the above mentioned matters, this study was done to compare the Latin keywords was in the articles published in the Journal of Mazandaran University of Medical Sciences. This is a descriptive study. The data were extracted from the key words of Englsih abstracts of articles published in the years 2009-2010 in the Journal of Mazandaran University of Medical Sciences by census method. Checklist of data collection is designed, based on research objectives and literature review which has face validity. Compliance rate in this study was to determine if the keywords cited in this article as a full subject of the main subject headings in a MeSH (Bold and the selected word) is a perfect adjustment. If keywords were cited in the article but the main heading is not discussed in the following main topics to be discussed with reference to See and See related it has considered has partial adjustment. Out of 148 articles published in 12 issues in proposed time of studying, 72 research papers were analyzed. The average numbers of authors in each article were 4 ± 1. Results showed that most of specialty papers 42 (58. 4%), belonging to the (Department of Clinical Sciences) School of Medicine, 11 (15.3%) Basic Science, 6(8.4%) Pharmacy, Nursing and Midwifery 5(6.9%), 4(5.5%) Health, paramedical Sciences 3(4.2%), and non medical article 1(1.3%) school of medicine. In general, results showed that 80 (30%) of key words have been used to complete the adjustment. Also, only 1(1.4%) had complete adjustment with all the MeSH key words and in 8 articles(11.4%) key words of had no adjustment with MeSH. The results showed that only

    Prehospital, small-volume resuscitation of combat casualties with a synthetic colloid (6% hydroxyethyl starch [HES] 670/0.75) has been recommended when blood or blood components are unavailable. We studied hemostatic effects of a newer synthetic colloid (6% HES, 130/0.4) compared with either a natural colloid (albumin) or to crystalloids in an uncontrolled hemorrhage model. Spontaneously breathing New Zealand white rabbits (3.4 ± 0.1 kg) were anesthetized, instrumented, and subjected to a splenic injury with uncontrolled bleeding. Fifteen minutes after injury, rabbits were in shock (mean arterial pressure [MAP] = 26 ± 1.3 mm Hg, and received colloids (6% HES, 130/0.4 or 5% albumin at 15 mL/kg), or crystalloids (normal saline at 30 mL/kg or 5% hypertonic saline at 7.5 mL/kg) for resuscitation in two intravenous bolus injections (15 minutes apart) to raise their MAP to 65 mm Hg, n = 9/group. Animals were monitored for 2.5 hours or until death, and blood losses were measured. Blood samples were analyzed for arterial blood gas, complete blood count, and coagulation measures. There were no differences among groups in baseline measures and initial hemorrhage volume (11.9 ± 0.6 mL/kg) at 15 minutes postinjury. Twenty minutes after fluid resuscitation (1 hour postinjury), MAP was higher, shock indices were lower, and blood pH was higher in colloids versus. crystalloids groups (p colloid produced the largest hemodilution (54% decrease in hematocrit, p < 0.05 vs. hypertonic saline). Activated partial thromboplastin time increased approximately 35% above baseline in all groups except in 6% HES 130/0.4 group in which it doubled. Clot strength was reduced (15%) only in the 6% HES 130/0.4 group. 6% HES 130/0.4 resuscitation produced the largest blood loss and 33% survival rate that was not different than the crystalloid groups. Albumin produced the best hemostatic and survival outcomes (78%). Small-volume resuscitation with crystalloids appeared inadequate to treat

    It has become highly desirable to provide users with flexible ways to query/search information over databases as simple as keyword search like Google search. This book surveys the recent developments on keyword search over databases, and focuses on finding structural information among objects in a database using a set of keywords. Such structural information to be returned can be either trees or subgraphs representing how the objects, that contain the required keywords, are interconnected in a relational database or in an XML database. The structural keyword search is completely different from

    2017-01-01

    In the present era, thesauri as tools in indexing play an effective role in integrating retrieval preventing fragmentation as well as a multiplicity of terminologies and also in providing information content of documents. This study aimed to investigate the keywords of articles indexed in IranMedex in terms of origin, structure and indexing situation and their Compliance with the Persian Medical Thesaurus and Medical Subject Headings (MeSH). This study is an applied research, and a survey has been conducted. Statistical population includes 32,850 Persian articles which are indexed in the IranMedex during the years 1385-1391. 379 cases were selected as sample of the study. Data collection was done using a checklist. In analyzing the findings, the SPSS Software were used. Although there was no significant difference in terms of indexing origin between the proportion of different types of the Persian and English keywords of articles indexed in the IranMedex, the compliance rates of the Persian and English keywords with the Persian medical thesaurus and MeSH were different in different years. In the meantime, the structure of keywords is leaning more towards phrase structure, and a single word structure and the majority of keywords are selected from the titles and abstracts. The authors' familiarity with the thesauri and controlled tools causes homogeneity in assigning keywords and also provides more precise, faster, and easier retrieval of the keywords. It's suggested that a mixture of natural and control languages to be used in this database in order to reach more comprehensive results.

  14. Hybrid keyword search auctions

    KAUST Repository

    Goel, Ashish

    2009-01-01

    Search auctions have become a dominant source of revenue generation on the Internet. Such auctions have typically used per-click bidding and pricing. We propose the use of hybrid auctions where an advertiser can make a per-impression as well as a per-click bid, and the auctioneer then chooses one of the two as the pricing mechanism. We assume that the advertiser and the auctioneer both have separate beliefs (called priors) on the click-probability of an advertisement. We first prove that the hybrid auction is truthful, assuming that the advertisers are risk-neutral. We then show that this auction is superior to the existing per-click auction in multiple ways: 1. We show that risk-seeking advertisers will choose only a per-impression bid whereas risk-averse advertisers will choose only a per-click bid, and argue that both kind of advertisers arise naturally. Hence, the ability to bid in a hybrid fashion is important to account for the risk characteristics of the advertisers. 2. For obscure keywords, the auctioneer is unlikely to have a very sharp prior on the click-probabilities. In such situations, we show that having the extra information from the advertisers in the form of a per-impression bid can result in significantly higher revenue. 3. An advertiser who believes that its click-probability is much higher than the auctioneer\\'s estimate can use per-impression bids to correct the auctioneer\\'s prior without incurring any extra cost. 4. The hybrid auction can allow the advertiser and auctioneer to implement complex dynamic programming strategies to deal with the uncertainty in the click-probability using the same basic auction. The per-click and per-impression bidding schemes can only be used to implement two extreme cases of these strategies. As Internet commerce matures, we need more sophisticated pricing models to exploit all the information held by each of the participants. We believe that hybrid auctions could be an important step in this direction. The

    To investigate the effect of Bromocriptine-QR on glycemic control in patients with type 2 diabetes whose glycemia is poorly controlled on one or two oral anti-diabetes agents. Five hundred fifteen Type 2 Diabetes Mellitus (T2DM) subjects (ages 18 to 80 and average body mass index [BMI] of 32.7) with baseline HbA1c ≥ 7.5 and on one or two oral anti-diabetes (OAD) medications (metformin, sulfonylurea, and/or thiazolidinediones) were randomized 2:1 to bromocriptine-QR (1.6 to 4.8 mg/day) or placebo for a 24 week treatment period. Study investigators were allowed to adjust, if necessary, subject anti-diabetes medications during the study to attempt to achieve glycemic control in case of glycemic deterioration. The impact of bromocriptine-QR treatment intervention on glycemic control was assessed in subjects on any one or two OADs (ALL treatment category) (N = 515), or on metformin with or without another OAD (Met/OAD treatment category) (N = 356), or on metformin plus a sulfonylurea (Met/SU treatment category) (N = 245) 1) by examining the between group difference in change from baseline a) concomitant OAD medication changes during the study, and b) HbA1c and 2) by determining the odds of reaching HbA1c of ≤ 7.0% on bromocriptine-QR versus placebo.

    1979-09-01

    You have heard about issues surrounding indexing and retrieval of nuclear records and automation and micrographics of these records. Now we are going to get each of you involved in indexing and assigning keywords. The first part of this hands-on workshop will be a very basic, elementary step-by-step introduction, concentrating on how to assign keywords. It is a workshop for beginners, People who have never done it before. It is planned to demonstrate what an analyst has to do to index and assign keywords to a document. Then I will take some pages of a report and demonstrate how I choose keywords for it. Then each of you will have a chance to do the same thing with similar pages from another report. Then we will discuss the variations ln the keywords you individually assigned. There are many systems that can be used. In this particular workshop we will cover only a system of building your own keyword listing as you index your documents. We will be discussing keywords or descriptors or subject words, but first I want to point out a few other critical points about indexing. When developing an indexing project the most important thing to do first lS decide what elements you want to retrieve by. Whether you go into a large computer retrieval system or a small three-by-five card system, you have to decide in advance what you want to retrieve. Then you can go on from there. If you only need to search by equipment number or by purchase order or by contract number, then you can use a very simple retrieval system. But if you want to be able to retrieve a record by any combination of elements, then you have to consistently input these into your system. For example, if you want to be able to ask for the drawings of the piping in the secondary cooling system, level 3, manufactured by a certain vendor, then you must have put the information into the index by a retrieval file point, in advance. I want to stress that the time spent in deciding what has to be retrievable is never

    1999-01-01

    Bibliographic databases were developed from the traditional library card catalogue in order to enable users to access library documents via various types of bibliographic information, such as title, author, series or conference date. In addition these catalogues sometimes contained some form of indexation by subject, such as the Universal (or Dewey) Decimal Classification used for books. With the introduction of the eprint archives, set up by the High Energy Physics (HEP) Community in the early 90s, huge collections of documents in several fields have been made available on the World Wide Web. These developments however have not yet been followed up from a keywording point of view. We will see in this paper how important it is to attribute keywords to all documents in the area of HEP Grey Literature. As libraries are facing a future with less and less manpower available and more and more documents, we will explore the possibility of being helped by automatic classification software. We will specifically menti...

  10. Keyword Ontology Development for Discovering Hydrologic Data

    Science.gov (United States)

    Piasecki, Michael; Hooper, Rick; Choi, Yoori

    2010-05-01

    Supply of adequate keywords in data searches is a key element to building search clients. This is particularly true for science or engineering areas that straddle many subjects such as the hydrology field. The main difficulties that arise when trying to search across many disparate data holdings is that there are no norms that describe data sets uniformly (this is a lack of common metadata profiles) in particular when it comes to identifying them with recognizable labels. This leads to problems associated with hyponymy (a word or phrase whose semantic range is included within that of another) and synonymy (several terms are used to describe the same thing or parameter). Particularly the latter is endemic in the hydrologic data world and poses a substantial obstacle when trying to build information systems that can search for data across multiple data sources. This paper discusses the effort that has been undertaken within the Consortium of Universities for the Advancement of Hydrologic Sciences Inc. (CUAHSI: http://www.cuahsi.org) Hydrologic Information Systems (HIS) development group to overcome these semantic heterogeneities by developing a keyword ontology that can be navigated to identify search keywords of ascending or descending generality to identify parameter sets or fairly specific parameters that the search engine should be searching for. The general is to tag or connect any variable name to a presented leaf concept in the ontology that best describes what a specific data set represents. While the search environment is not part of this paper, we will describe the underlying ontology, its extent, the way it is organized and why, and what sources and considerations were taken into account in developing the current version. An initial ontology of 4033 leaf concepts describing physical, chemical and biological properties has been developed. These leaf concepts cover the vast majority of the records contained in major data sources such as the US Geological

    Two experiments were used to assess the efficacy of the keyword mnemonic method in adults. In Experiment 1, immediate and delayed recall (at a one-day interval) were assessed by comparing the results obtained by a group of adults using the keyword mnemonic method in contrast to a group using the repetition method. The mean age of the sample under study was 59.35 years. Subjects were required to learn a list of 16 words translated from Latin into Spanish. Participants who used keyword mnemonics that had been devised by other experimental participants of the same characteristics, obtained significantly higher immediate and delayed recall scores than participants in the repetition method. In Experiment 2, other participants had to learn a list of 24 Latin words translated into Spanish by using the keyword mnemonic method reinforced with pictures. Immediate and delayed recall were significantly greater in the keyword mnemonic method group than in the repetition method group.

    As an information retrieval system, PubMed(®) aims at providing efficient access to documents cited in MEDLINE(®). For this purpose, it relies on matching representations of documents, as provided by authors and indexers to user queries. In this paper, we describe the growth of author keywords in biomedical journal articles and present a comparative study of author keywords and MeSH(®) indexing terms assigned by MEDLINE indexers to PubMed Central Open Access articles. A similarity metric is used to assess automatically the relatedness between pairs of author keywords and indexing terms. A set of 300 pairs is manually reviewed to evaluate the metric and characterize the relationships between author keywords and indexing terms. Results show that author keywords are increasingly available in biomedical articles and that over 60% of author keywords can be linked to a closely related indexing term. Finally, we discuss the potential impact of this work on indexing and terminology development.

    This paper introduces a novel and domain-independent method for automatically extracting keywords, as sequences of one or more words, from individual documents. We describe the method’s configuration parameters and algorithm, and present an evaluation on a benchmark corpus of technical abstracts. We also present a method for generating lists of stop words for specific corpora and domains, and evaluate its ability to improve keyword extraction on the benchmark corpus. Finally, we apply our method of automatic keyword extraction to a corpus of news articles and define metrics for characterizing the exclusivity, essentiality, and generality of extracted keywords within a corpus.

  14. XQSuggest: An Interactive XML Keyword Search System

    Science.gov (United States)

    Li, Jiang; Wang, Junhu

    Query suggestion is extensively used in web search engines to suggest relevant queries, which can help users better express their information needs. In this paper, we explore the application of query suggestion in xml keyword search and propose a novel interactive xml query system XQSuggest, which mainly targets non-professional users who roughly know the contents of the database. Our system extends conventional keyword search systems by instantly suggesting several understandable semantic strings after each keyword is typed in, so that the users can easily select their desired semantic string, which represents a specific meaning of the keyword, to replace the ambiguous keyword. We provide a novel algorithm to compute the final results. Experimental results are provided to verify the better effectiveness of our system.

    The Global Change Master Directory (GCMD) Keywords are a hierarchical set of controlled Earth Science vocabularies that help ensure Earth science data and services are described in a consistent and comprehensive manner and allow for the precise searching of collection-level metadata and subsequent retrieval of data and services. Initiated over twenty years ago, the GCMD Keywords are periodically analyzed for relevancy and will continue to be refined and expanded in response to user needs. This talk explores the current status of the GCMD keywords, the value and usage that the keywords bring to different tools/agencies as it relates to data discovery, and how the keywords relate to SWEET (Semantic Web for Earth and Environmental Terminology) Ontologies.

    1997-10-01

    We tackle the problem of multimedia indexing using keyword spotting on the spoken part of the data. Word spotting systems for indexing have to meet vary hard specifications: short response times to queries, speaker independent mode, open vocabulary in order to be able to track any keyword. To meet these constraints keyword models should be build according to their phonetic spelling and the process should be divided in two parts: preprocessing of the speech signal and query over a lattice of hypotheses. Different classification criteria have been studied for hypothesis generation: frame labeling, maximum likelihood and maximum a posteriori (MAP). The hypothesis probability is computed either through standard gaussian model or through a hybrid Hidden Markov Model-Neural Network. The training of the phonemic models is based either on Viterbi alignment or on recursive estimation and maximization of a posteriori probabilities. In the latter discriminant properties between phonemes are enforced. Tests have been conducted on TIMIT database as well as on TV news soundtracks. Interesting results have been obtained in time saving for the documentalist. The ultimate goal is to couple the soundtrack indexing with tools for video indexing in order to enhance the robustness of the system.

    Smooth muscle cell contraction in the airways is the principal therapeutic target in asthmatic subjects and its insufficient treatment is often a cause of uncontrolled disease. For this reason, research has focused on targeting smooth muscle activity with anticholinergic agents, including umeclidinium. Areas covered: This review highlights the potential application of umeclidinium, a long acting muscarinic antagonist, as a novel therapeutic approach for patients with severe uncontrolled asthma, despite maximal therapy. Expert opinion: Umeclidinium, similarly to tiotropium, which has been recently included in guidelines, may act by contrasting cholinergic activation in airways, preventing or at least reducing smooth muscle cells contraction and the consequent bronchoconstriction. This is similar to what occurs in chronic obstructive pulmonary disease, for which umeclidinium has been regularly approved. However, available data is not sufficient and further studies are needed before regulatory approval can be sought, since only phase II clinical trials have been conducted at present. Both quality of life and objectifiable clinical data and parameters must be assessed, including lung function improvements, reduction of exacerbations and reduction of as required medications.

    In postcolonial Melanesia, cultural discourses are increasingly organised around creole words, i.e. keywords of Bislama (Vanuatu) and Tok Pisin (Papua New Guinea). These words constitute (or represent) important emerging ethnolinguistic worldviews, which are partly borne out of the colonial era......, and partly out of postcolonial ethno-rhetoric. This chapter explores the word kastom ‘traditional culture’ in Bislama and pasin bilong tumbuna ‘the ways of the ancestors’ in Tok Pisin. Specific attention is paid to the shift from “negative “ to “positive” semantics, following from the re...

    Since the publication, 9 years ago, of the latest SEPAR (Spanish Society of Pulmonology and Thoracic Surgery) Guidelines on Difficult-to-Control Asthma (DCA), much progress has been made in the understanding of asthmatic disease. These new data need to be reviewed, analyzed and incorporated into the guidelines according to their level of evidence and recommendation. Recently, consensus documents and clinical practice guidelines (CPG) addressing this issue have been published. In these guidelines, specific mention will be made of what the previous DCA guidelines defined as "true difficult-to-control asthma". This is asthma that remains uncontrolled after diagnosis and a systematic evaluation to rule out factors unrelated to the disease itself that lead to poor control ("false difficult-to-control asthma"), and despite an appropriate treatment strategy (Spanish Guidelines for the Management of Asthma [GEMA] steps 5 and 6): severe uncontrolled asthma. In this respect, the guidelines propose a revised definition, an attempt to classify the various manifestations of this type of asthma, a proposal for a stepwise diagnostic procedure, and phenotype-targeted treatment. A specific section has also been included on DCA in childhood, aimed at assisting healthcare professionals to improve the care of these patients. Copyright © 2014 SEPAR. Published by Elsevier Espana.

    Methods and systems for rapid automatic keyword extraction for information retrieval and analysis. Embodiments can include parsing words in an individual document by delimiters, stop words, or both in order to identify candidate keywords. Word scores for each word within the candidate keywords are then calculated based on a function of co-occurrence degree, co-occurrence frequency, or both. Based on a function of the word scores for words within the candidate keyword, a keyword score is calculated for each of the candidate keywords. A portion of the candidate keywords are then extracted as keywords based, at least in part, on the candidate keywords having the highest keyword scores.

    Emotion words play a vital role in many sentiment analysis tasks. Previous research uses sentiment dictionary to detect the subjectivity or polarity of words. In this paper, we dive into Emotion-Inducing Keywords (EIK), which refers to the words in use that convey emotion. We first analyze an emotion corpus to explore the pragmatic aspects of EIK. Then we design an effective framework for automatically detecting EIK in sentences by utilizing linguistic features and context information. Our system outperforms traditional dictionary-based methods dramatically in increasing Precision, Recall and F1-score.

    Full Text Available In this paper, I claim that subjectivity is a way of being that is constituted through a set of practices in which the self is subject to the dangers of fictionalizing and plotting her life and self-image. I examine some ways of becoming subject through narratives and through theatrical performance before others. Through these practices, a real and active subjectivity is revealed, capable of self-knowledge and self-transformation.

    The incidence of hypertension (HTN) has increased rapidly in the Sudan in the last few years. The aim of this study was to determine the prevalence of uncontrolled HTN and the risk factors associated with it in Sudanese adults. This study was cross sectional. Data were collected using structured questionnaires filled in during interviews with subjects visiting referral clinics in Khartoum, the capital city of Sudan. Blood pressure (BP) was measured using a digital sphygmomanometer. A digital balance was used for determination of body weight and a traditional cloth tape measure was used for measuring height, for calculation of body mass index. This study included 200 subjects, 46% male and 54% female. In the whole study, 82% of subjects (p history of HTN and 52% were smokers. Uncontrolled BP was found to be significantly (p education (55%) and workers (41%). In these groups, when genders were considered separately, uncontrolled hypertension was significantly (p education (67 and 40%, respectively), and in workers (86 and 10%, respectively). Uncontrolled HTN was associated with overweight and obesity in 45 and 29% of the subjects, respectively. Most of the interviewed subjects were not aware of the consequences of HTN and its associated risk factors. Uncontrolled HTN was associated with risk factors of HTN and lifestyle, and was more prominent in the male gender. The ignorance of the interviewed subjects about HTN, its associated risk factors, changes in lifestyle and adherence to taking the medication may have been a major factor in the prevalence of uncontrolled HTN.

    The present study was a subgroup analysis of a Pan-Asian Phase 3 open-label randomized treat-to-target trial evaluating insulin degludec/insulin aspart (IDegAsp) and biphasic insulin aspart 30 (BIAsp 30) in Japanese subjects with type 2 diabetes inadequately controlled on insulin. Eligible subjects (n = 178) were randomized (2: 1) to twice-daily (b.i.d.) IDegAsp or BIAsp 30 with or without metformin for 26 weeks, titrated to a blood glucose target of between 3.9 and <5.0 mmol/L. Changes in HbA1c , the proportion of responders reaching the HbA1c target, and changes in fasting plasma glucose, nine-point self-monitored plasma glucose profiles, and body weight were assessed. At 26 weeks, the decrease in HbA1c was similar in both groups. Fasting plasma glucose was lower with IDegAsp than BIAsp 30 (estimated treatment difference -1.50 mmol/L; 95 % confidence interval [CI] -1.98, -1.01). Overall confirmed hypoglycemia rates were similar; the nocturnal confirmed hypoglycemia rate was lower with IDegAsp than BIAsp 30 (estimated rate ratio 0.44; 95 % CI 0.20, 0.99). No severe hypoglycemic episodes were reported. The results indicate that IDegAsp b.i.d. improves glycemic control and, compared with BIAsp 30, lowers the rate of nocturnal confirmed hypoglycemia. © 2016 The Authors.

    This study compared the efficacy and tolerability of taspoglutide versus pioglitazone in subjects with type 2 diabetes inadequately controlled with sulphonylurea ± metformin. In this double-blind, double-dummy, parallel-group trial, 760 subjects (49% male, age 56.4 years, diabetes duration 8.8 years, body mass index 32.7 kg/m(2) and haemoglobin A1c [HbA1c] 8.3%) were randomized (1 : 1 : 1) to subcutaneous injections of taspoglutide 10 or 20 mg once weekly or oral pioglitazone 45 mg daily. The primary endpoint was change in HbA1c after 24 weeks. Mean (±s.e.) HbA1c reductions with taspoglutide 10 (-1.18 ± 0.08%) and 20 mg (-1.36 ± 0.08%) were non-inferior to pioglitazone (-1.30 ± 0.08%) (p = 0.21 and 0.37, respectively); mean treatment differences were 0.12 (95% confidence interval: -0.03, -0.26) and -0.06 (-0.20, 0.08) for taspoglutide 10 and 20 mg versus pioglitazone. Mean (±s.e.) changes in body weight (kg) were -0.8 ± 0.3, -1.0 ± 0.3 and 3.6 ± 0.3 for taspoglutide 10 and 20 mg and pioglitazone, respectively; 8, 11 and 1% of patients achieved ≥5% weight loss. A higher incidence of adverse events (AEs) occurred with taspoglutide, predominantly gastrointestinal disturbances and injection-site reactions, resulting in higher rates of discontinuation versus pioglitazone. No treatment differences in serious AEs were observed. Taspoglutide offered good glycaemic control similar to pioglitazone, while achieving beneficial weight loss rather than weight gain, but was associated with more AEs. Due to the higher than expected discontinuation rates, mainly because of gastrointestinal intolerability, the taspoglutide clinical programme was stopped. © 2012 Blackwell Publishing Ltd.

    Discovering Earth science data can be complex if the catalog holding the data lacks structure. Controlled keyword vocabularies within metadata catalogues can improve data discovery. NASA's Global Change Master Directory's (GCMD) Keyword Management System (KMS) is a recently released a RESTful web service for managing and providing access to controlled keywords (science keywords, service keywords, platforms, instruments, providers, locations, projects, data resolution, etc.). The KMS introduces a completely new paradigm for the use and management of the keywords and allows access to these keywords as SKOS Concepts (RDF), OWL, standard XML, and CSV. A universally unique identifier (UUID) is automatically assigned to each keyword, which uniquely identifies each concept and its associated information. A component of the KMS is the keyword manager, an internal tool that allows GCMD science coordinators to manage concepts. This includes adding, modifying, and deleting broader, narrower, or related concepts and associated definitions. The controlled keyword vocabulary represents over 20 years of effort and collaboration with the Earth science community. The maintenance, stability, and ongoing vigilance in maintaining mutually exclusive and parallel keyword lists is important for a "normalized" search and discovery, and provides a unique advantage for the science community. Modifications and additions are made based on community suggestions and internal review. To help maintain keyword integrity, science keyword rules and procedures for modification of keywords were developed. This poster will highlight the use of the KMS as a beneficial service for the stewardship and access of the GCMD keywords. Users will learn how to access the KMS and utilize the keywords. Best practices for managing an extensive keyword hierarchy will also be discussed. Participants will learn the process for making keyword suggestions, which subsequently help in building a controlled keyword

    Binge eating disorder (BED) is associated with obesity and major depressive disorder (MDD). Naltrexone extended-release (ER)/bupropion ER (NB) is approved as an adjunct to diet and physical activity for chronic weight management. In a prospectively designed 24-week open-label, single-arm, single-site trial of 25 women with MDD and overweight/obesity, NB reduced weight and depressive symptoms. This post hoc analysis investigated the relationship between change in self-reported binge eating behavior (evaluated with the Binge Eating Scale [BES]) and changes in weight, control of eating, and depressive symptoms. At baseline, 91% of subjects had moderate or severe BES scores, suggesting BED. BES scores were significantly improved from week 4, and by week 24, 83% reported "little or no problem." Improvement in BES scores correlated with improvement in depressive symptoms and control of eating. NB may be effective in reducing binge eating symptoms associated with MDD and overweight/obesity. Evaluation of NB in BED appears warranted. Orexigen Therapeutics, Inc.

    1996-12-01

    Uncontrolled buying, defined by the presence of repetitive impulsive and excessive buying that leads to personal and familial distress, is a psychiatric disorder that has only recently been recognized. This review focuses on the prevalence, clinical features, and etiology of this disorder. All published articles on the topic were collected and reviewed. The literature concerning the typology of normal consumerism was also reviewed. The prevalence of the disorder in the general population is reported to be 1.1%. The main clinical features of uncontrolled buying are impulsivity and repetition of buying, the invasive need to buy, unsuccessful attempts to control spending, and the existence of tangible negative consequences of buying (marked distress, interference with social or occupational functioning, or financial problems). Uncontrolled buying may be related to obsessive-compulsive disorder, depression, addiction, or impulsivity. In most cases, uncontrolled buying can be understood as "compensatory buying" that temporarily alleviates depressive symptoms and can thus be associated with the results of antidepressant treatment in cases in which uncontrolled buying is symptomatically associated with depression.

    2002-03-01

    Most information retrieval systems rely on the user to provide a set of keywords that the retrieved documents should contain. However, when the objective is to search for documents that is similar to a given document, the system has to choose the keywords from that document first. Automatic selection of keywords is not a trivial task as one word may be a keyword in one context but a very common word in others, and require significant domain specific knowledge. In this paper we describe a method for choosing keywords from a document within a given corpus automatically using text data-mining technique. The key idea is to score the words within the document based on the clustering result of the entire corpus. We applied the scheme to a Software Trouble Report (STR) corpus and obtained highly relevant keywords and search result.

  1. An effective suggestion method for keyword search of databases

    KAUST Repository

    Huang, Hai

    2016-09-09

    This paper solves the problem of providing high-quality suggestions for user keyword queries over databases. With the assumption that the returned suggestions are independent, existing query suggestion methods over databases score candidate suggestions individually and return the top-k best of them. However, the top-k suggestions have high redundancy with respect to the topics. To provide informative suggestions, the returned k suggestions are expected to be diverse, i.e., maximizing the relevance to the user query and the diversity with respect to topics that the user might be interested in simultaneously. In this paper, an objective function considering both factors is defined for evaluating a suggestion set. We show that maximizing the objective function is a submodular function maximization problem subject to n matroid constraints, which is an NP-hard problem. An greedy approximate algorithm with an approximation ratio O((Formula presented.)) is also proposed. Experimental results show that our suggestion outperforms other methods on providing relevant and diverse suggestions. © 2016 Springer Science+Business Media New York

    Full Text Available Keyword search on encrypted data allows one to issue the search token and conduct search operations on encrypted data while still preserving keyword privacy. In the present paper, we consider the keyword search problem further and introduce a novel notion called attribute-based proxy re-encryption with keyword search (ABRKS, which introduces a promising feature: In addition to supporting keyword search on encrypted data, it enables data owners to delegate the keyword search capability to some other data users complying with the specific access control policy. To be specific, ABRKS allows (i the data owner to outsource his encrypted data to the cloud and then ask the cloud to conduct keyword search on outsourced encrypted data with the given search token, and (ii the data owner to delegate other data users keyword search capability in the fine-grained access control manner through allowing the cloud to re-encrypted stored encrypted data with a re-encrypted data (embedding with some form of access control policy. We formalize the syntax and security definitions for ABRKS, and propose two concrete constructions for ABRKS: key-policy ABRKS and ciphertext-policy ABRKS. In the nutshell, our constructions can be treated as the integration of technologies in the fields of attribute-based cryptography and proxy re-encryption cryptography.

    2016-05-01

    Full Text Available Most approaches to keywords discovery when analyzing microblogging messages (among them those from Twitter are based on statistical and lexical information about the words that compose the text. The lack of context in the short messages can be problematic due to the low co-occurrence of words. In this paper, we present a new approach for keywords discovering from Spanish tweets based on the addition of context information using Wikipedia as a knowledge base. We present four different ways to use Wikipedia and two ways to rank the new keywords. We have tested these strategies using more than 60000 Spanish tweets, measuring performance and analyzing particularities of each strategy.

    2007-07-01

    Full Text Available Asthma is a common chronic illness that imposes a heavy burden on all aspects of the patient's life, including personal and health care cost expenditures. To analyze the direct cost associated to uncontrolled asthma patients, a cross-sectional study was conducted to determine costs related to patients with uncontrolled and controlled asthma. Uncontrolled patient was defined by daytime symptoms more than twice a week or nocturnal symptoms during two consecutive nights or any limitations of activities, or need for relief rescue medication more than twice a week, and an ACQ score less than 2 points. A questionnaire about direct cost stratification in health services, including emergency room visits, hospitalization, ambulatory visits, and asthma medications prescribed, was applied. Ninety asthma patients were enrolled (45 uncontrolled/45 controlled. Uncontrolled asthmatics accounted for higher health care expenditures than controlled patients, US$125.45 and US$15.58, respectively [emergency room visits (US$39.15 vs US$2.70 and hospitalization (US$86.30 vs US$12.88], per patient over 6 months. The costs with medications in the last month for patients with mild, moderate and severe asthma were US$1.60, 9.60, and 25.00 in the uncontrolled patients, respectively, and US$6.50, 19.00 and 49.00 in the controlled patients. In view of the small proportion of uncontrolled subjects receiving regular maintenance medication (22.2% and their lack of resources, providing free medication for uncontrolled patients might be a cost-effective strategy for the public health system.

    The goal of asthma management is to achieve disease control; however, despite the availability of effective and safe medications, for many patients asthma remains uncontrolled. One reason for this is the fear of long-term side effects from the regular use of inhaled corticosteroids (ICSs). Adverse...... effects of poorly controlled asthma (for example, obesity, pneumonia, and risks to the fetus) can be perceived as side effects of ICSs. Poorly controlled asthma adversely affects children's cardiovascular fitness, while children with well-controlled asthma perform at the same level as their peers....... Children with uncontrolled asthma also have a higher frequency of obesity than children with controlled asthma. Stress can affect asthma control, and children with poorly controlled asthma are more likely to have learning disabilities compared with those with good control. In adults, focused attention...

    Acute compartment syndrome is increased tissue pressure exceeding perfusion pressure in a closed compartment resulting in nerve and muscle ischemia. Common precipitating causes are crush injuries, burns, substance abuse, osseous or vascular limb trauma. This is a case of 42year old female with history of hypothyroidism who presented to emergency room with acute onset of severe pain and swelling in right lower extremity. Physical examination was concerning for acute compartment syndrome of right leg which was confirmed by demonstration of elevated compartmental pressures. No precipitating causes were readily identified. Further laboratory testing revealed uncontrolled hypothyroidism. Management included emergent fasciotomy and initiating thyroid hormone replacement. This case represents a rare association between acute compartment syndrome and uncontrolled hypothyroidism. We also discuss the pathogenesis of compartment syndrome in hypothyroid patients and emphasize the importance of evaluating for less common causes, particularly in setting of non-traumatic compartment syndrome.

    The theory of dissipativity is well developed for controllable systems. A more appropriate definition of dissipativity in the context of uncontrollable systems is in terms of the existence of a storage function, namely a function such that, along every system trajectory, its rate of change at each time instant is at most the power supplied to the system at that time. However, even when the supplied power is expressible in terms of just the external variables, the dissipativity property for uncontrollable systems crucially hinges on whether or not the storage function depends on variables unobservable/hidden from the external variables: this paper investigates the key aspects of both cases, and also proposes another intuitive definition of dissipativity. These three definitions are compared: we show that drawbacks of one definition are addressed by another. Dealing first with observable storage functions, under the conditions that no two uncontrollable poles add to zero and that dissipativity is strict as frequency tends to infinity, we prove that the dissipativities of a system and its controllable part are equivalent. We use the behavioural approach for formalising key notions: a system behaviour is the set of all system trajectories. We prove that storage functions have to be unobservable for 'lossless' uncontrollable systems. It is known, however, that unobservable storage functions result in certain 'fallacious' examples of lossless systems. We propose an intuitive definition of dissipativity: a system/behaviour is called dissipative if it can be embedded in a controllable dissipative superbehaviour. We prove embeddability results and use them to resolve the fallacy in the example termed 'lossless' due to unobservable storage functions. We next show that, quite unreasonably, the embeddability definition admits behaviours that are both strictly dissipative and strictly antidissipative. Drawbacks of the embeddability definition in the context of RLC circuits are

    2013-12-01

    We propose a bayesian framework for keyword spotting in handwritten documents. This work is an extension to our previous work where we proposed dynamic background model, DBM for keyword spotting that takes into account the local character level scores and global word level scores to learn a logistic regression classifier to separate keywords from non-keywords. In this work, we add a bayesian layer on top of the DBM called the variational dynamic background model, VDBM. The logistic regression classifier uses the sigmoid function to separate keywords from non-keywords. The sigmoid function being neither convex nor concave, exact inference of VDBM becomes intractable. An expectation maximization step is proposed to do approximate inference. The advantage of VDBM over the DBM is multi-fold. Firstly, being bayesian, it prevents over-fitting of data. Secondly, it provides better modeling of data and an improved prediction of unseen data. VDBM is evaluated on the IAM dataset and the results prove that it outperforms our prior work and other state of the art line based word spotting system.

    2012-07-01

    Full Text Available Like in Output Data as HTML File, this lesson takes the frequency pairs collected in Counting Frequencies and outputs them in HTML. This time the focus is on keywords in context (KWIC which creates n-grams from the original document content – in this case a trial transcript from the Old Bailey Online. You can use your program to select a keyword and the computer will output all instances of that keyword, along with the words to the left and right of it, making it easy to see at a glance how the keyword is used. Once the KWICs have been created, they are then wrapped in HTML and sent to the browser where they can be viewed. This reinforces what was learned in Output Data as HTML File, opting for a slightly different output. At the end of this lesson, you will be able to extract all possible n-grams from the text. In the next lesson, you will be learn how to output all of the n-grams of a given keyword in a document downloaded from the Internet, and display them clearly in your browser window.

    Abstract. This paper deals with targeted testing of timed systems with uncontrollable behavior. The testing activity is viewed as a game between the tester and the system under test (SUT) towards a given test purpose. The SUT is modeled as Timed Game Automaton and the test purpose is specified...... in Timed CTL formula. We can employ a timed game solver UPPAAL-TIGA to check if the test purpose is ture w.r.t. the model, and if yes, to generate a winning strategy and use it for black-box conformance testing. Specifically, we show that in case the checking yields a negative result, we can still test...... the SUT against the test purpose as long as the SUT reacts to our moves in a cooperative style. We present an operational framework of cooperative winning strategy generation, test case derivation and execution. The test method is proved to be sound and complete. Preliminary experimental results indicate...

    2017-01-01

    We present the results of a comprehensive multi-pass analysis of visualization paper keywords supplied by authors for their papers published in the IEEE Visualization conference series (now called IEEE VIS) between 1990-2015. From this analysis we derived a set of visualization topics that we discuss in the context of the current taxonomy that is used to categorize papers and assign reviewers in the IEEE VIS reviewing process. We point out missing and overemphasized topics in the current taxonomy and start a discussion on the importance of establishing common visualization terminology. Our analysis of research topics in visualization can, thus, serve as a starting point to (a) help create a common vocabulary to improve communication among different visualization sub-groups, (b) facilitate the process of understanding differences and commonalities of the various research sub-fields in visualization, (c) provide an understanding of emerging new research trends, (d) facilitate the crucial step of finding the right reviewers for research submissions, and (e) it can eventually lead to a comprehensive taxonomy of visualization research. One additional tangible outcome of our work is an online query tool (http://keyvis.org/) that allows visualization researchers to easily browse the 3952 keywords used for IEEE VIS papers since 1990 to find related work or make informed keyword choices.

    2017-09-07

    In some patients with moderate-to-severe asthma, particularly those with noneosinophilic inflammation, the disease remains uncontrolled. This trial evaluated the efficacy and safety of tezepelumab (AMG 157/MEDI9929), a human monoclonal antibody specific for the epithelial-cell-derived cytokine thymic stromal lymphopoietin (TSLP), in patients whose asthma remained uncontrolled despite treatment with long-acting beta-agonists and medium-to-high doses of inhaled glucocorticoids. In this phase 2, randomized, double-blind, placebo-controlled trial, we compared subcutaneous tezepelumab at three dose levels with placebo over a 52-week treatment period. The primary end point was the annualized rate of asthma exacerbations (events per patient-year) at week 52. The use of tezepelumab at a dose of 70 mg every 4 weeks (low dose; 145 patients), 210 mg every 4 weeks (medium dose; 145 patients), or 280 mg every 2 weeks (high dose; 146 patients) resulted in annualized asthma exacerbation rates at week 52 of 0.26, 0.19, and 0.22, respectively, as compared with 0.67 in the placebo group (148 patients). Thus, exacerbation rates in the respective tezepelumab groups were lower by 61%, 71%, and 66% than the rate in the placebo group (Pliters with the low dose [P=0.01], 0.11 liters with the medium dose [P=0.02], and 0.15 liters with the high dose [P=0.002]). A total of 2 patients in the medium-dose group, 3 in the high-dose group, and 1 in the placebo group discontinued the trial regimen because of adverse events. Among patients treated with long-acting beta-agonists and medium-to-high doses of inhaled glucocorticoids, those who received tezepelumab had lower rates of clinically significant asthma exacerbations than those who received placebo, independent of baseline blood eosinophil counts.

  6. [Loss and uncontrolled use of radioactive sources].

    Science.gov (United States)

    Govaerts, P

    2005-01-01

    In the course of history, exposure to radioactive sources escaping regular control, has been the main cause of fatal accidents, with the exception of the reactor accident at Chernobyl. After the disintegration of the Soviet Union, numerous lost sources have been found, sometimes with serious physical damage. The attacks of September 11, 2001 have focussed the attention on the possibility of nuclear terrorism. Although the risks of fatal consequences are rather limited, the possible uncontrolled exposure to ionizing radiation has an important psycho-social impact on the population. After a brief survey of the types of radioactive sources for medical and industrial applications and a discussion of the risks and exposure routes, possible scenarios are illustrated by well documented case histories. The main conclusions of this analysis are: Radioactive materials are not unique as a potential threat by toxic materials. The most serious consequences for individuals occur as the result of external radiation, mostly with skin contact with medium-active sources which are relatively easily accessible. The collective impact is mostly psycho-social and is more important for a dispersed contamination of the environment. Many sources are detected via medical complaints. The knowledge of the specific symptoms is consequently very important. A dispersion of radioactive contamination has usually considerable economic consequences. Accidents occur particularly, but certainly not exclusively, in relatively unstable countries. Change of owner or final evacuation of the source constitute a critical phase in many scenarios.

    Full Text Available Abstract This paper highlights the importance of the interoperability of the encrypted DB in terms of the characteristics of DB and efficient schemes. Although most prior researches have developed efficient algorithms under the provable security, they do not focus on the interoperability of the encrypted DB. In order to address this lack of practical aspects, we conduct two practical approaches--efficiency and group search in cloud datacenter. The process of this paper is as follows: first, we create two schemes of efficiency and group search--practical keyword index search--I and II; second, we define and analyze group search secrecy and keyword index search privacy in our schemes; third, we experiment on efficient performances over our proposed encrypted DB. As the result, we summarize two major results: (1our proposed schemes can support a secure group search without re-encrypting all documents under the group-key update and (2our experiments represent that our scheme is approximately 935 times faster than Golle's scheme and about 16 times faster than Song's scheme for 10,000 documents. Based on our experiments and results, this paper has the following contributions: (1 in the current cloud computing environments, our schemes provide practical, realistic, and secure solutions over the encrypted DB and (2 this paper identifies the importance of interoperability with database management system for designing efficient schemes.

  8. On the Controllability Principles and the Construction of Uncontrollability

    DEFF Research Database (Denmark)

    Friis, Ivar; Gevoll, Linn; Hansen, Allan

    A key challenge when it comes to coping with the controllability principle is to understand why and how uncontrollability occurs. In this paper we draw on the Actor-Network Theory to provide more insight to why and how uncontrollability emerges in organizations. By means of an in-depth case study...... of a wide range of heterogeneous actors that connects in multiple ways and that in combination forms a complex network of relations which affect delivery time performance. Our study adds to research on the controllability principle. Whereas prior research has characterized uncontrollability as determined...... uncontrollability more specifically is about. Thus, our study adds to as well as elaborates on prior research. We illustrate how uncontrollability arise in the intersects of several heterogeneous elements such as the product information systems, quality management, incentive systems, outsourcing and customers.

    1993-01-01

    Although millions of dollars have helped to improve the operability and technology of ground data systems for mission operations, almost all mission documentation remains bound in printed volumes. This form of documentation is difficult and timeconsuming to use, may be out-of-date, and is usually not cross-referenced with other related volumes of mission documentation. A more effective, automated method of mission information access is needed. A new method of information management for mission operations using automated keyword referencing is proposed. We expound on the justification for and the objectives of this concept. The results of a prototype tool for mission information access that uses a hypertextlike user interface and existing mission documentation are shared. Finally, the future directions and benefits of our proposed work are described.

  10. UNCONTROLLED PHOTOMULTIPLIER CURRENT IN PHOTOEMISSION ANALYSIS

    2016-01-01

    Full Text Available The dependence of photon energy from energy of photoelectron is base of photoemission radiation analysis. In such photoemission measurements except current of photocathode is always exist a reverse current from the collector of electrons to the photocathode in two-electrode sensors. There are various ways of reverse and uncontrolled current eliminating or reducing their influence. The constructive method is based on creating an electron-optical system of photoelectronic device, which would be a photoelectron energy analyzer. The second method – technological. However, it requires the manufacture of the photocathode and the dynode system in different vacuum chamber with subsequent connection to a single device in vacuum environment without exposure to the atmosphere. The purpose of this article is to determinate the effect of photoemission from photocathode chamber and the first dynode of photomultiplier on energy distribution of the photoelectrons from photocathode. To solve this problem authors obtained calibration curves for measuring pyrometer module ПИФ 4/2 with ФЭУ-114 as a sensor at supply voltage 1350 V and different decelerating voltages. The effect of illumination on the value of modulation coefficient on temperature k(T and wavelength k(λ is shown. In temperature measurements, this effect is evident in fact that at temperatures below 1400 K linear dependence ln k – T-1 is broken. Still this linear dependence is a necessary consequence of the fact that the measured temperature is color temperature. However, this calibration curve can be used to measure low temperature if the target measurements condition and calibration conditions are identical. In wavelength calibration, curve k(λ at λ > 760 nm is two-valued, that doesn’t allow to identify monochromatic radiation by this method and bring in errors in temperature measurements. 

  11. Imagined Affordance: Reconstructing a Keyword for Communication Theory

    Directory of Open Access Journals (Sweden)

    Peter Nagy

    2015-09-01

    Full Text Available In this essay, we reconstruct a keyword for communication—affordance. Affordance, adopted from ecological psychology, is now widely used in technology studies, yet the term lacks a clear definition. This is especially problematic for scholars grappling with how to theorize the relationship between technology and sociality for complex socio-technical systems such as machine-learning algorithms, pervasive computing, the Internet of Things, and other such “smart” innovations. Within technology studies, emerging theories of materiality, affect, and mediation all necessitate a richer and more nuanced definition for affordance than the field currently uses. To solve this, we develop the concept of imagined affordance. Imagined affordances emerge between users’ perceptions, attitudes, and expectations; between the materiality and functionality of technologies; and between the intentions and perceptions of designers. We use imagined affordance to evoke the importance of imagination in affordances—expectations for technology that are not fully realized in conscious, rational knowledge. We also use imagined affordance to distinguish our process-oriented, socio-technical definition of affordance from the “imagined” consensus of the field around a flimsier use of the term. We also use it in order to better capture the importance of mediation, materiality, and affect. We suggest that imagined affordance helps to theorize the duality of materiality and communication technology: namely, that people shape their media environments, perceive them, and have agency within them because of imagined affordances.

  13. Formalizing An Approach to Curate the Global Change Master Directory (GCMD)'s Controlled Vocabularies (Keywords) Through a Keyword Governance Process and Community Involvement

    Science.gov (United States)

    Stevens, T.

    2016-12-01

    NASA's Global Change Master Directory (GCMD) curates a hierarchical set of controlled vocabularies (keywords) covering Earth sciences and associated information (data centers, projects, platforms, and instruments). The purpose of the keywords is to describe Earth science data and services in a consistent and comprehensive manner, allowing for precise metadata search and subsequent retrieval of data and services. The keywords are accessible in a standardized SKOS/RDF/OWL representation and are used as an authoritative taxonomy, as a source for developing ontologies, and to search and access Earth Science data within online metadata catalogs. The keyword curation approach involves: (1) receiving community suggestions; (2) triaging community suggestions; (3) evaluating keywords against a set of criteria coordinated by the NASA Earth Science Data and Information System (ESDIS) Standards Office; (4) implementing the keywords; and (5) publication/notification of keyword changes. This approach emphasizes community input, which helps ensure a high quality, normalized, and relevant keyword structure that will evolve with users' changing needs. The Keyword Community Forum, which promotes a responsive, open, and transparent process, is an area where users can discuss keyword topics and make suggestions for new keywords. Others could potentially use this formalized approach as a model for keyword curation.

We present a 34-year old hemodialysis patient with new onset of uncontrolled hypertension, erythropoietin-resistant anemia, thrombocytopenia, and Bell’s palsy. On admission, his blood pressure (BP was 210/110 mmHg and he had petechiae and purpura at upper and lower extremities. Renal ultrasonography (USG showed bilaterally enlarged kidneys without hydronephrosis, unlike his previous USG, which determined bilaterally atrophic kidneys. Acute lymphoblastic leukemia, hypertensive crisis due to bilateral leukemic cell infiltration of kidneys, tumor lysis syndrome, and leukemic involvement of the facial nerve were diagnosed. Despite intense antihypertensive management, his BP was not controlled. After prednisolone, daunorubicine, and vincristine therapy, the size of kidneys diminished and his BP dropped under normal range. In conclusion, pathological findings such as uncontrolled hypertension, flank pain, skin rashes, and abnormal blood count should be considered carefully, even in patients with end-stage renal disease receiving renal replacement therapy.Keywords: leukemic cell infiltration, uncontrolled hypertension, hemodialysis

Garlic supplements have shown promise in the treatment of uncontrolled hypertension, and the mechanism of action is biologically plausible. Our trial is the first to assess the effect of aged garlic extract on central blood pressure and arterial stiffness, regarded as important risk factors for cardiovascular morbidity. Subjects and methods: A total of 88 general practice patients and community members with uncontrolled hypertension completed a double-blind randomized placebo-controlled trial of 12 weeks investigating the effect of daily intake of aged garlic extract (1.2 g containing 1.2 mg S-allylcysteine or placebo on blood pressure, and secondary outcome measures of central-hemodynamics and other cardiovascular markers, including cholesterol, homocysteine, platelet function, and inflammatory markers. Results: Mean blood pressure was significantly reduced by 5.0±2.1 mmHg (P=0.016 systolic, and in responders by 11.5±1.9 mmHg systolic and 6.3±1.1 mmHg diastolic compared to placebo (P<0.001. Central hemodynamic-measures tended to improve in the garlic group more than in the placebo group, including central blood pressure, central pulse pressure, mean arterial pressure, augmentation pressure, pulse-wave velocity, and arterial stiffness. While changes in other cardiovascular markers did not reach significance due to small numbers in subgroups with elevated levels, trends in beneficial effects of garlic on the inflammatory markers TNFα, total cholesterol, low-density lipid cholesterol, and apolipoproteins were observed. Aged garlic extract was highly tolerable and acceptable, and did not increase the risk of bleeding in patients on blood

    To evaluate the current status of blood pressure (BP) control as measured at home and in the office, as well as to clarify and compare the prevalence and characteristics of isolated uncontrolled hypertension as measured at home (home hypertension) and in the office (office hypertension). A cross-sectional study. Primary care offices in Japan. A sample of 3400 patients with essential hypertension (mean age, 66 years; males, 45%) receiving antihypertensive treatment. Overall, the mean home systolic BP (SBP)/diastolic BP (DBP) was 140/82 mmHg, and the mean office SBP/DBP was 143/81 mmHg. Of the 3400 subjects, 19% had controlled hypertension (home SBP/DBP office SBP/DBP home hypertension (home SBP/DBP >/= 135/85 mmHg and office SBP/DBP office hypertension (home SBP/DBP office SBP/DBP home SBP/DBP >/= 135/85 mmHg and office SBP/DBP >/= 140/90 mmHg). Compared to controlled hypertension, factors associated with isolated uncontrolled home hypertension included obesity, relatively higher office SBP, habitual drinking, and the use of two or more prescribed antihypertensive drugs. Compared to uncontrolled hypertension, factors associated with isolated uncontrolled office hypertension included female gender, lower body mass index, and relatively lower office SBP. The use of all four, three of four, or all three predictive factors might be useful for the clinician to suspect isolated uncontrolled home or office hypertension.

    Keeping abreast of trends in the articles and rapidly grasping a body of article's key points and relationship from a holistic perspective is a new challenge in both literature research and text mining. As the important component, keywords can present the core idea of the academic article. Usually, articles on a single theme or area could share one or some same keywords, and we can analyze topological features and evolution of the articles co-keyword networks and keywords co-occurrence networks to realize the in-depth analysis of the articles. This paper seeks to integrate statistics, text mining, complex networks and visualization to analyze all of the academic articles on one given theme, complex network(s). All 5944 ;complex networks; articles that were published between 1990 and 2013 and are available on the Web of Science are extracted. Based on the two-mode affiliation network theory, a new frontier of complex networks, we constructed two different networks, one taking the articles as nodes, the co-keyword relationships as edges and the quantity of co-keywords as the weight to construct articles co-keyword network, and another taking the articles' keywords as nodes, the co-occurrence relationships as edges and the quantity of simultaneous co-occurrences as the weight to construct keyword co-occurrence network. An integrated method for analyzing the topological features and evolution of the articles co-keyword network and keywords co-occurrence networks is proposed, and we also defined a new function to measure the innovation coefficient of the articles in annual level. This paper provides a useful tool and process for successfully achieving in-depth analysis and rapid understanding of the trends and relationships of articles in a holistic perspective.

    Full Text Available Keyword search is one of the most friendly and intuitive information retrieval methods. Using the keyword search to get the connected subgraph has a lot of application in the graph-based cognitive computation, and it is a basic technology. This paper focuses on the top-k keyword searching over graphs. We implemented a keyword search algorithm which applies the backward search idea. The algorithm locates the keyword vertices firstly, and then applies backward search to find rooted trees that contain query keywords. The experiment shows that query time is affected by the iteration number of the algorithm.

    2016-01-01

    NASA's Global Change Master Directory (GCMD) develops and expands a hierarchical set of controlled vocabularies (keywords) covering the Earth sciences and associated information (data centers, projects, platforms, instruments, etc.). The purpose of the keywords is to describe Earth science data and services in a consistent and comprehensive manner, allowing for the precise searching of metadata and subsequent retrieval of data and services. The keywords are accessible in a standardized SKOSRDFOWL representation and are used as an authoritative taxonomy, as a source for developing ontologies, and to search and access Earth Science data within online metadata catalogues. The keyword development approach involves: (1) receiving community suggestions, (2) triaging community suggestions, (3) evaluating the keywords against a set of criteria coordinated by the NASA ESDIS Standards Office, and (4) publication/notification of the keyword changes. This approach emphasizes community input, which helps ensure a high quality, normalized, and relevant keyword structure that will evolve with users changing needs. The Keyword Community Forum, which promotes a responsive, open, and transparent processes, is an area where users can discuss keyword topics and make suggestions for new keywords. The formalized approach could potentially be used as a model for keyword development.

    The aim of this study was to evaluate the effect of ambient temperature on the physical and chemical characteristics of the longissimus dorsi muscle by comparing the quality of meat from pigs reared in a controlled and in an uncontrolled environment, the latter provided with a shallow pool. Twenty castrated male pigs of the Topigs line were randomly allotted to two treatments: a controlled environment, with constant temperature (22 °C) and relative humidity (70%); and an uncontrolled environment in a conventional shed for rearing pigs equipped with a shallow pool, where pigs were subject to climatic variations. Meat from pigs kept in the controlled environment showed a greater capacity to retain intracellular water, higher tenderness, and lower cholesterol levels than meat from pigs reared in the uncontrolled environment, but displayed higher lipid oxidation and a lower concentration of DHA. Treatments had no effect on color, pH, chemical composition, or fatty acid profile (except DHA concentration). Rearing pigs in sheds equipped with a shallow pool minimizes the effects of environmental heat on meat quality, allowing the production of high-quality meat in warm climate regions without expensive investments. Animals reared in an uncontrolled environment equipped with a shallow pool are able to produce meat with characteristics within the quality standards and with similar quality to that of meat from animals raised in controlled environment.

    This study aimed to explore positive and negative factors affecting the employability in patients with uncontrolled seizures. Semistructured interviews with 21 patients with uncontrolled seizures were analyzed using interpretative phenomenological analysis. Eleven (52.4%) of the participants interviewed were employed; 7 were holding full-time position with more than 4years of working experience. The mean age was 34.6years, 71.4% were female, 38% were married, 71.4% had at least 11years of education, 38% had a driving license, 19% received government monetary aid, 66.7% had seizure onset before reaching 17years of age, 66.7% experienced monthly seizures, and 76% were on polytherapy. A total of 6 main themes were found to be affecting the employability among people with uncontrolled seizures: (a) ability to work; (b) intention to work; (c) support and stigma at workplace; (d) family support, overdependence, and protection; (e) life event; and (f) government and welfare support. Subthemes under the main theme ability to work included education, cognitive and physical functions, ability to continue working after seizures, ability to travel to work, self-perceived ability to work, and ability to cope with stress. Many shared the same idea that employment is important, but their intention to work varied. The employed group tended to work for a future goal and self-satisfaction, and the unemployed group tended to have no or lack intention to work. Positive factors were noted in the following themes: ability to work; intention to work; support and stigma at workplace; and family support, overdependence, and protection. There were internal and external factors affecting the employability among people with uncontrolled seizures both positively and negatively. Positive internal factors such as ability and intention to work require further exploration. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Cerebral venous sinus thrombosis is a rare form of stroke caused by thrombosis in venous sinuses of the brain. In this study, we reported on a patient with venous sinus thrombosis and brucellosis who presented with uncontrolled seizure despite being treated with anti-epileptic drugs at high doses. The case was a 33-year-old woman with a history of controlled complex partial seizure who presented with headache, asthenia, and uncontrolled seizure for one month. She was febrile and a brain CT scan indicated hemorrhagic focus in the left posterior parietal and the temporal lobe. Magnetic resonance imaging and magnetic resonance venography also proved venous sinus thrombosis in the left transverse sinus. Besides [In addition], a laboratory assessment confirmed brucellosis. Following the treatment with anti-coagulant, anti-brucellosis, and anti-epileptic agents, the patient was discharged in good condition with medical orders. Clinical suspicion and accurate evaluation of a patient′s history is the most important clue in diagnosis and treatment of brucellosis and cerebral venous sinus thrombosis, especially in uncontrolled seizure in patients who had previously been under control.

    Evidence to inform clinical practice is reliant on research carried out using appropriate study design. The objectives of this work were to (i) identify the prevalence of articles reporting on human studies using uncontrolled intervention or observational research designs published in peer-reviewed dental journals and (ii) determine the nature of recommendations made by these articles. Six peer-reviewed dental journals were selected. Issues published in January to June 2013 were examined and the types of articles published categorized. Following pre-defined inclusion/exclusion criteria, human studies classified as using uncontrolled intervention or observational research designs were subject to detailed review by two independent investigators, to examine if they presented clinical, policy or research recommendations and if these recommendations were supported by the data presented. 52.9% (n = 156) of studies published during the time period met the inclusion criteria. Studies with uncontrolled intervention or observational research designs comprised a larger proportion of the primary research studies published in the journals with lower impact factors (73.3%; n = 107) compared to the high impact journals (38.9%; n = 49). Analysis showed that 60.9% (n = 95) of the included studies made recommendations for clinical practice/dental policy. In 28.2% (n = 44) of studies, the clinical/policy recommendations made were judged to not be fully supported by the data presented. Many studies published in the current dental literature, which are not considered to produce strong evidence, make recommendations for clinical practice or policy. There were some cases when the recommendations were not fully supported by the data presented. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Bronchial asthma is a prevalent chronic allergic disease of lungs at early ages. A priority  task in allergology  is to search  biological  markers  related  to uncontrolled atopic  bronchial asthma. Cytokines fulfill their distinct function in pathogenesis of atopic  bronchial asthma, participating at the initiation, development and persistence of allergic inflammation in airways, causing different  variations of clinical course of the disease (with  respect  to its acuteness, severity, frequency of exacerbations. The  present  work has studied  indices  of cellular  and  humoral links of immunity, as well as levels of some  pro and  anti-inflammatory cytokines in peripheral blood serum (IL-4, IL-10, IL-2 and TNFα, aiming to determine potential markers of uncontrolled atopic bronchial asthma in children. A group of Caucasian (European children was involved into the research: Cohort 1, moderate atopic  bronchial asthma with controlled course during the last 3 months (n = 59; Cohort 2, severe/moderate-severe atopic bronchial asthma with uncontrolled course of the disease within last 3 months (n = 51,  Cohort 3 – control, practically healthy  children without signs of atopy  (n = 33. All the  children included in the group with atopic  bronchial asthma underwent regular mono/combined basic therapy  at high/ intermediate therapeutic doses.  We performed a comparative analysis  of cell  population indices  reflecting certain cellular  immunity links,  and  determined significantly  lower  levels of CD3+   lymphocytes, as well as decrease in relative  and  absolute  contents of CD4+  and  CD8+  cells in the  cohort with  uncontrolled course of atopic  bronchial asthma, as compared with controlled-course cohort. When  evaluating concentrations  of cytokines in peripheral blood serum of the patients with controlled and uncontrolled atopic  bronchial asthma, we revealed  significantly  higher

    Bloodstain age is a parameter that can be used in crime scene investigations. Bloodstain age can be determined by measuring the 18S rRNA:β-actin mRNA ratio by Reverse Transcription-quantitative PCR (RT-qPCR). Since this ratio is a function of time, it can be used as an estimator of bloodstain age. However, it is important to validate the technique in a variety of scenarios before it can be applied. We investigated 18S rRNA:β-actin mRNA ratio in bloodstains from sixteen Chinese subjects in 28 days under uncontrolled room conditions. The ratio changed in a linear fashion. It was also found that the subjects' gender affected the relationship between time and the RNA ratio. Copyright © 2012 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

    Resistant hypertension is a clinical condition in which blood pressure (BP) control is not achieved under a pharmacological therapy including a diuretic and at least two additional antihypertensive drug classes. To discuss an unusual presentation of uncontrolled hypertension despite multiple anti-hypertensive medications. A 46-year-old woman presented with resistant hypertension (HT) and with a long history of polydipsia, polyuria, weight loss and psychiatric symptoms (sudden onset of personality disorder with free anxiety, negativism and asthenia) unsuccessfully treated with antidepressant drugs. Tests for secondary HT showed a marked increase of serum renin and aldosterone both in clinostatic (342 pg/ml and 907 pmol/l, respectively) and orthostatic posture (351 pg/ml and 2845 pmol/l, respectively), hypokalemia (2.9 mmol/l) and macroalbuminuria (431 mg/day). Diagnostic examinations also revealed a focal stenosis of approximately 70 % of the proximal right renal artery with post-stenotic dilation. After percutaneous balloon angioplasty and stent implantation, BP was normalized with 5 mg/day amlodipine and psychiatric symptoms suddenly disappeared. Psychopathological symptoms are rare at the onset of hyperaldosteronism, and their aetiology is not well defined. A proper diagnostic and therapeutic process is mandatory in order to get the recommended therapeutic targets in short-midterm improving long-term prognosis. We also suggest not considering depressed or treat with antidepressant agents a young hypertensive subject with uncontrolled hypertension despite multiple anti-hypertensive medications without having ruled out a secondary form of hypertension.

    Full Text Available Data stored in the cloud servers, keyword search, and access controls are two important capabilities which should be supported. Public-keyword encryption with keyword search (PEKS and attribute based encryption (ABE are corresponding solutions. Meanwhile, as we step into postquantum era, pairing related assumption is fragile. Lattice is an ideal choice for building secure encryption scheme against quantum attack. Based on this, we propose the first mathematical model for lattice-based authorized searchable encryption. Data owners can sort the ciphertext by specific keywords such as time; data users satisfying the access control hand the trapdoor generated with the keyword to the cloud sever; the cloud sever sends back the corresponding ciphertext. The security of our schemes is based on the worst-case hardness on lattices, called learning with errors (LWE assumption. In addition, our scheme achieves attribute-hiding, which could protect the sensitive information of data user.

  15. BeppoSAX equatorial uncontrolled re-entry

    Portelli, C.

    The X-ray astronomy satellite BeppoSAX (Satellite per Astronomia X, "Beppo" in honor of Giuseppe Occhialini), is a project of the Italian Space Agency (ASI) with participation of the Netherlands Agency for Aerospace Programs (NIVR). BeppoSAX was launched by an Atlas G Centaur directly into a circular 600 km- orbit at 3.9 degrees inclination on April 30th, 1996. The satellite is a three axis stabilized spacecraft with a total mass of about 1400 kg. The current (May 1, 2002) flight altitude is about 470 km and its uncontrolled re-entry is predicted late in 2002, or in 2003, with a 26 kg of hydrazine on board that could not be vented or used for controlled re-entry due to gyro's package total failure. Due to the relatively high mass of BeppoSAX, it has to be expected that parts of the satellite will survive the re-entry into the earth atmosphere. The Italian Space Agency has committed a study to HTG for the analysis of the destructive phase of the uncontrolled atmospheric re-entry by means of a dedicated European software tool (SCARAB). The expected outputs will be used in order to determine how much of the spacecraft and how many fragments parts of it will reach the ground on the equatorial earth zone. This paper will address the peculiarities of the spacecraft initial status, its risks at end of life and the SCARAB modelling as well as its 6D flight dynamics re-entry analysis results also in terms of the destruction history tree. Consideration will be made on the ground dispersion and casualt y area due to the very restricted equatorial zone impacted. References B. Fritsche, H. Klinkrad, A.

    2017-11-01

    Dietary nitrate has been shown to increase nitrate/nitrite levels in multiple populations, with potential blood pressure lowering effects. However, there are few reports among hypertensives. We aimed to assess the effect of daily nitrate in subjects with controlled hypertension vs. uncontrolled hypertension. On day 0, hypertensives wore an ambulatory BP monitor (ABPM) for 24 h and fasting blood was taken. Subjects then consumed concentrated beetroot juice (12.9 mmol nitrate) for 14 consecutive days. On day 14 subjects consumed their last nitrate dose after fasting blood was drawn and again had an ABPM for 24 h. According to baseline ABPM, 11 subjects had controlled BP while 8 had uncontrolled BP. There were similar, significant increases in serum nitrate/nitrite in both groups. We observed little change in BP variables among controlled hypertensives. However, there were reductions in BP variables in uncontrolled hypertensives where decreases in nighttime DBP (-6 ± 4.8 mmHg), arterial stiffness (-0.08 ± 0.03 ambulatory arterial stiffness index) and LDL (-0.36 ± 0.42 mmol/L) reached significance (p = 003, 0.05 and 0.046, respectively). Our results support the existing data suggesting an anti-hypertensive effect of nitrate-containing beetroot juice, but only among those with uncontrolled hypertension.

  19. Patent Keyword Extraction Algorithm Based on Distributed Representation for Patent Classification

    Directory of Open Access Journals (Sweden)

    2018-02-01

    Full Text Available Many text mining tasks such as text retrieval, text summarization, and text comparisons depend on the extraction of representative keywords from the main text. Most existing keyword extraction algorithms are based on discrete bag-of-words type of word representation of the text. In this paper, we propose a patent keyword extraction algorithm (PKEA based on the distributed Skip-gram model for patent classification. We also develop a set of quantitative performance measures for keyword extraction evaluation based on information gain and cross-validation, based on Support Vector Machine (SVM classification, which are valuable when human-annotated keywords are not available. We used a standard benchmark dataset and a homemade patent dataset to evaluate the performance of PKEA. Our patent dataset includes 2500 patents from five distinct technological fields related to autonomous cars (GPS systems, lidar systems, object recognition systems, radar systems, and vehicle control systems. We compared our method with Frequency, Term Frequency-Inverse Document Frequency (TF-IDF, TextRank and Rapid Automatic Keyword Extraction (RAKE. The experimental results show that our proposed algorithm provides a promising way to extract keywords from patent texts for patent classification.

    2011-06-01

    Full Text Available An image processing algorithm for detecting individual weeds was developed and evaluated. Weed detection processes included were normalized excessive green conversion, statistical threshold value estimation, adaptive image segmentation, median filter, morphological feature calculation and Artificial Neural Network (ANN. The developed algorithm was validated for its ability to identify and detect weeds and crop plants under uncontrolled outdoor illuminations. A machine vision implementing field robot captured field images under outdoor illuminations and the image processing algorithm automatically processed them without manual adjustment. The errors of the algorithm, when processing 666 field images, ranged from 2.1 to 2.9%. The ANN correctly detected 72.6% of crop plants from the identified plants, and considered the rest as weeds. However, the ANN identification rates for crop plants were improved up to 95.1% by addressing the error sources in the algorithm. The developed weed detection and image processing algorithm provides a novel method to identify plants against soil background under the uncontrolled outdoor illuminations, and to differentiate weeds from crop plants. Thus, the proposed new machine vision and processing algorithm may be useful for outdoor applications including plant specific direct applications (PSDA.

  1. Public Key Encryption with Keyword Search from Lattices in Multiuser Environments

    Full Text Available A public key encryption scheme with keyword search capabilities is proposed using lattices for applications in multiuser environments. The proposed scheme enables a cloud server to check if any given encrypted data contains certain keywords specified by multiple users, but the server would not have knowledge of the keywords specified by the users or the contents of the encrypted data, which provides data privacy as well as privacy for user queries in multiuser environments. It can be proven secure under the standard learning with errors assumption in the random oracle model.

    Searchable encryption is an important cryptographic primitive that enables privacy-preserving keyword search on encrypted electronic medical records (EMRs) in cloud storage. Efficiency of such searchable encryption in a medical cloud storage system is very crucial as it involves client platforms such as smartphones or tablets that only have constrained computing power and resources. In this paper, we propose an efficient secure-channel free public key encryption with keyword search (SCF-PEKS) scheme that is proven secure in the standard model. We show that our SCF-PEKS scheme is not only secure against chosen keyword and ciphertext attacks (IND-SCF-CKCA), but also secure against keyword guessing attacks (IND-KGA). Furthermore, our proposed scheme is more efficient than other recent SCF-PEKS schemes in the literature.

    The aim of this study was to evaluate uncontrolled removal of dentin during in vitro ultrasonic irrigant activation in prepared root canals using 2 different files. Fifty-four human single-rooted teeth with straight root canals were prepared to size 35/.06 taper. The specimens were randomly allocated to 3 groups (n = 18). Two milliliters of 2% sodium hypochlorite was delivered 3 times to each root canal by a syringe and an open-ended needle. After each delivery, the irrigant was ultrasonically activated for 10 seconds at 35% power either by a size 15 ultrasonic K-file (group A) or a size 20 Irrisafe file (Acteon Satelec, Merignac, France) (group B) placed at 2 mm short of the working length. The irrigant in the control specimens (group C) was not activated. Specimens were scanned by micro-computed tomographic imaging at 10-μm voxel size before preparation, after preparation, and after the final irrigation/activation sequence. Scans were coregistered and segmented, and the amount of dentin removed during the final step was quantified by morphologic operations. Results were analyzed by nonparametric statistical tests. The level of significance was set to P ultrasonic files removed significantly more dentin than irrigant delivery in the control group (P ≤ .005). K-files removed significantly more dentin than Irrisafe files in the apical third (P = .001). Ultrasonic irrigant activation may result in uncontrolled removal of dentin in straight root canals and at manufacturer-recommended power settings.

    Full Text Available Purpose: To evaluate the safety and efficacy of viscocanalostomy in the management of medically uncontrollable primary open-angle glaucoma (POAG in a developing country. Materials and Methods: This is a prospective, non-randomized case series of 14 consecutive eyes with medically uncontrollable POAG, all subjected to viscocanalostomy. The main outcome measure was success rate based on the intraocular pressure (IOP level achieved post-operatively. The procedure was considered a complete success if IOP was less than 21 mmHg without any anti-glaucoma medication. Qualified success was defined as IOP of less than 21 mmHg with anti-glaucoma medication. All patients had a regular follow-up of at least 12 months. Results: IOP was reduced from a mean baseline value of 27.9 ± 7.3 mmHg (range: 21-40 mmHg to a mean final value of 16.0 ± 2.7 mmHg (range: 13-22 mmHg, which was statistically highly significant (P < 0.005. The mean number of pre-operative anti-glaucoma medications was 3.0 ± 0.4 (range: 2-4, which was reduced significantly (P < 0.0001 to 0.3 ± 0.6 (range: 0-2 at the last follow-up visit. One year post-operatively, complete success was achieved in 71% and qualified success was observed in 21.4% of patients, summing up to an overall success rate of 92.4%. There were no major complications in any of the patients. Conclusion: Viscocanalostomy could be performed effectively and safely for control of POAG in developing countries.

    We assessed the association between adherence to antihypertensive drug treatment and patient's perception of uncontrolled blood pressure (BP) in diabetic hypertensive subjects. This was a cross-sectional study that evaluated adherence to antihypertensives (Morisky questionnaire), patients' perception of abnormal BP, office BP, and ambulatory BP monitoring in diabetic hypertensive subjects. We evaluated 323 patients, 65.2% women, aged 56.5 ± 7 years, glycosylated hemoglobin (HbA1c) 8.0% (range, 6.9%-9.6%), diabetes duration of 10 years (range, 5-17 years). Adherence to drug treatment was 51.4%. Patients who reported hypertension-related symptoms (60.4%) had a lower level of adherence (P hypertension-related symptoms (P anti-hypertensives, age, and duration of diabetes). Non-adherents had higher office diastolic BP (83.6 ± 11.9 vs. 79.8 ± 9.9; P = .003), but no difference between groups was observed considering systolic, diastolic, and mean BP evaluated by ambulatory BP monitoring. Low rates of adherence to antihypertensive drug treatment were observed in outpatient hypertensive diabetic subjects. Perception of uncontrolled BP levels was strongly and independently associated with non-adherence. Non-adherence determined repercussion on office BP that may have clinical implications in cardiovascular risk. Copyright © 2013 American Society of Hypertension. Published by Elsevier Inc.

    The need to sedate terminally ill patients for uncontrolled symptoms has been previously documented in a few reports. A retrospective consecutive chart review was undertaken at a hospice in Cape Town, South Africa, to develop an understanding of the local experience and assess the potential for improved patient management. Twenty-three of seventy-six (30%) patients received sedating therapies: twenty patients for delirium, two patients for delirium and dyspnea, and one patient for dyspnea alone. Fourteen patients were sedated with a continuous subcutaneous infusion of midazolam, seven patients with intermittent doses of benzodiazepines, and two patients with chlorpromazine and lorazepam. The mean midazolam dose was 29 mg per day (median 30 mg; range 15-60 mg per day). Patients were sedated on average 2.5 days before death (median 1 day; range 4 hours-12 days). The mean equivalent daily dose of parenteral morphine in the last week of life showed a significantly higher mean for the sedated group, as compared to the nonsedated group. There was minimal investigation of reversible causes for delirium, none of the patients underwent an opioid rotation, and the opioid dose was seldom decreased. None of the patients received parenteral hydration. The prevalence for the use of sedating treatment is consistent with the range of other literature reports. Nevertheless, the wide disparity in the reported prevalence of these problems, and the ethical concerns raised by the relative frequency of this sedative approach, cannot be ignored.

    Older adults with disability might have been increasing due to the rapid aging of society. Many studies showed that physical activity is an essential part for improving quality of life in later lives. Regular physical activity is an efficient means that has roles of primary prevention and secondary prevention. However, there were few studies regarding older adults with disability and physical activity participation. The purpose of this current study was to investigate restriction factors to regularly participate older adults with disability in physical activity by employing keyword network analysis. Two hundred twenty-nine older adults with disability who were over 65 including aging with disability and disability with aging in type of physical disability and brain lesions defined by disabled person welfare law partook in the open questionnaire assessing barriers to participate in physical activity. The results showed that the keyword the most often used was 'Traffic' which was total of 21 times (3.47%) and the same proportion as in the 'personal' and 'economical'. Exercise was considered the most central keyword for participating in physical activity and keywords such as facility, physical activity, disabled, program, transportation, gym, discomfort, opportunity, and leisure activity were associated with exercise. In conclusion, it is necessary to educate older persons with disability about a true meaning of physical activity and providing more physical activity opportunities and decreasing inconvenience should be systematically structured in Korea.

    Full Text Available The Semantic Web (Web 3.0 has been proposed as an efficient way to access the increasingly large amounts of data on the internet. The Linked Open Data Cloud project at present is the major effort to implement the concepts of the Seamtic Web, addressing the problems of inhomogeneity and large data volumes. RKBExplorer is one of many repositories implementing Open Data and contains considerable bibliographic information. This paper discusses bibliographic data, an important part of cloud data. Effective searching of bibiographic datasets can be a challenge as many of the papers residing in these databases do not have sufficient or comprehensive keyword information. In these cases however, a search engine based on RKBExplorer is only able to use information to retrieve papers based on author names and title of papers without keywords. In this paper we attempt to address this problem by using the data mining algorithm Association Rule Mining (ARM to develop keywords based on features retrieved from Resource Description Framework (RDF data within a bibliographic citation. We have demonstrate the applicability of this method for predicting missing keywords for bibliographic entries in several typical databases. −−−−− Paper presented at 1st International Symposium on Big Data and Cloud Computing Challenges (ISBCC-2014 March 27-28, 2014.

    Najafi, Elham; Darooneh, Amir H

    2015-01-01

    A text can be considered as a one dimensional array of words. The locations of each word type in this array form a fractal pattern with certain fractal dimension. We observe that important words responsible for conveying the meaning of a text have dimensions considerably different from one, while the fractal dimensions of unimportant words are close to one. We introduce an index quantifying the importance of the words in a given text using their fractal dimensions and then ranking them according to their importance. This index measures the difference between the fractal pattern of a word in the original text relative to a shuffled version. Because the shuffled text is meaningless (i.e., words have no importance), the difference between the original and shuffled text can be used to ascertain degree of fractality. The degree of fractality may be used for automatic keyword detection. Words with the degree of fractality higher than a threshold value are assumed to be the retrieved keywords of the text. We measure the efficiency of our method for keywords extraction, making a comparison between our proposed method and two other well-known methods of automatic keyword extraction.

Commonly, intolerant patients are advised by physicians to avoid the offending foods (dairy foods, cereals, beans, etc. This food-limiting option, however, has possible nutritional risks. We have therefore evaluated the impact of using pure, enteric-coated α- plus ß-galactosidase on gut symptoms in intolerant subjects instead of avoidance of the offending foods. Methods: Sixteen subjects intolerant to lactose and/or complex carbohydrates were enrolled and evaluated in terms of gut symptoms with 1 uncontrolled diet, 2 diet devoid of offending foods, and 3 uncontrolled diet along with pure, enteric-coated α- and ß-galactosidase (DDM Galactosidase®. Results: Even with the uncontrolled diet, intolerant subjects treated with DDM Galactosidase® exhibited reduced gut symptoms (bloating, flatulence, diarrhea, and constipation significantly better than the control treatment as well as having a diet devoid of offending foods. Conclusion: DDM Galactosidase® is a valid and safe optional treatment to counteract lactose and complex carbohydrate intolerance in subjects who prefer not to avoid, at least partially, offending foods.

    Uncontrolled hypertension remains an important issue in daily clinical practice worldwide. Although the majority of patients are treated in primary care, most of the data on blood pressure control originate from population-based studies or secondary healthcare. The aim of this study was to evaluate the frequency of uncontrolled hypertension and associated risk factors among hypertensive patients followed at primary care facilities in Kinshasa, the capital city of Democratic Republic of the Congo. A sample of 298 hypertensive patients seen at primary healthcare facilities, 90 men and 208 women, aged ≥ 18 years, were consecutively included in this cross-sectional study. The majority (66%) was receiving monotherapy, and diuretics (43%) were the most used drugs. According to 2007 European Society of Hypertension/European Society of Cardiology hypertension guidelines, uncontrolled hypertension was defined as blood pressure ≥ 140/90 or ≥ 130/80 mmHg (diabetes or chronic kidney disease). Logistic regression analysis was used to identify the determinants of uncontrolled hypertension. Uncontrolled hypertension was observed in 231 patients (77.5%), 72 men and 159 women. Uncontrolled systolic blood pressure (SBP) was more frequent than uncontrolled diastolic blood pressure (DBP) and increased significantly with advancing age (p = 0.002). The proportion of uncontrolled SBP and DBP was significantly higher in patients with renal failure (p = 0.01) and those with high (p = 0.03) to very high (p = 0.02) absolute cardiovascular risk. The metabolic syndrome (OR 2.40; 95% CI 1.01-5.74; p = 0.04) emerged as the main risk factor associated with uncontrolled hypertension. Uncontrolled hypertension was common in this case series and was associated with factors related to lifestyle and diet, which interact with blood pressure control.

    The literature of drug-drug interaction (DDI)-related uncontrolled causality, and preventability of DDI-induced UCG (HbA1c >7%) in outpatients glycemia (UCG) among outpatients with Type 2 diabetes mellitus is still limited. The aim of this study is to identify the prevalence, mechanism, severity, with Type 2 diabetes. A cross-sectional study was conducted in Penang General Hospital. A computerized system for DDI checking was used to assess the severity and mechanism of DDIs. Drug interaction probability scale was used to evaluate the likelihood of DDIs. Preventability of DDIs has been determined by the instrument of Hallas. The UCG prevalence related to DDIs was further assessed. SPSS 21.00 was used in this study. From 425 outpatients with HbA1c% test, their mean age was 58.7 ± 12.8 years. Only 225 (52.9%) cases had controlled glycemia while 200 (47.1%) cases with UCG. They had multiple comorbidities, with a mean number of 3.8 ± 2.2/patient and often prescribed with multiple medications, with a mean number of 6.33 ± 4.67/patient. It has been detected that 86 DDIs causing UCG in 46 patients (23%) with range of (1 - 4) DDIs per patient. Drugs with DDI-induced UCG were as follows: diuretics (79%), salbutamol (9.2%), cortisones (5.8%), and others (6%). The majority of these DDIs were categorized as possible (77.9%) and preventable (37%). Nearly one-quarter of UCG was induced by DDIs; most of these DDIs are possible, and more than one-third are preventable. It was concluded that thiazide diuretics have the highest prevalence of DDI-related UCG.

    Full Text Available BACKGROUND: Patients with Diabetes Melitus are proven to be prone to atherosclerosis and coronary heart disease, especially type 2 Diabetes Melitus (T2DM patient who have higher risk and mortality for cardiovascular risk factor. The Dyslipidemia condition is very common in T2DM as one of the risk factors. Diabetic dyslipidemia is marked by the increased triglyceride (TG, low HDL cholesterol (HDL-C, and increased small dense LDL and apolipoprotein B. Therefore the aim of this study is to assess the differential and correlation between Atherogenic Index of Plasma (AIP, ratio of small dense low density lipoprotein (sdLDL/lecithin cholesterol acyl transferase (LCAT and ratio of sdLDL/cholesteryl ester transfer protein (CETP of controlled and uncontrolled T2DM. METHODS: This study was observational with cross sectional design. In total of 72 patients with T2DM consist of 36 controlled and 36 uncontrolled, participated in this study. The serum TG, HDL-C, sdLDL, LCAT and CETP were examined in their relationship with to T2DM risk. RESULTS: The results of the study indicate that the AIP (p<0.001 increase controlled and uncontrolled T2DM and the ratio of sdLDL/CETP (p=0.004, odds ratio of AIP was 4 (95% CI: 1.501-10.658 and odds ratio of sdLDL/CETP ratio was 4 (95% CI: 1.501-10.658 in uncontrolled T2DM. CONCLUSIONS: This study showed that the AIP and ratio of small dense LDL/CETP had a significant correlation with the uncontrolled T2DM. The AIP and ratio of small dense LDL/CETP increase was found at the uncontrolled T2DM to be 4 times greater than the controlled T2DM. KEYWORDS: T2DM, atherosclerosis, atherogenic index of plasma, small dense LDL, LCAT, CETP, ratio of sdLDL/LCAT, ratio of sdLDL/CETP.

    2014-01-01

    Social media postings are rich in information that often remain hidden and inaccessible for automatic extraction due to inherent limitations of the site's APIs, which mostly limit access via specific keyword-based searches (and limit both the number of keywords and the number of postings that are returned). When mining social media for drug mentions, one of the first problems to solve is how to derive a list of variants of the drug name (common misspellings) that can capture a sufficient number of postings. We present here an approach that filters the potential variants based on the intuition that, faced with the task of writing an unfamiliar, complex word (the drug name), users will tend to revert to phonetic spelling, and we thus give preference to variants that reflect the phonemes of the correct spelling. The algorithm allowed us to capture 50.4 - 56.0 % of the user comments using only about 18% of the variants.

    Digital watermarking has been recognized as a useful technology for the copyright protection and authentication of digital information. However, rarely did the former methods focus on the key content of digital carrier. The idea based on the protection of key content is more targeted and can be considered in different digital information, including text, image and video. In this paper, we use text as research object and a text zero-watermarking method which uses keyword dense interval (KDI) as the key content is proposed. First, we construct zero-watermarking model by introducing the concept of KDI and giving the method of KDI extraction. Second, we design detection model which includes secondary generation of zero-watermark and the similarity computing method of keyword distribution. Besides, experiments are carried out, and the results show that the proposed method gives better performance than other available methods especially in the attacks of sentence transformation and synonyms substitution.

    Full Text Available Abstract Background To date, many of the methods for information extraction of biological information from scientific articles are restricted to the abstract of the article. However, full text articles in electronic version, which offer larger sources of data, are currently available. Several questions arise as to whether the effort of scanning full text articles is worthy, or whether the information that can be extracted from the different sections of an article can be relevant. Results In this work we addressed those questions showing that the keyword content of the different sections of a standard scientific article (abstract, introduction, methods, results, and discussion is very heterogeneous. Conclusions Although the abstract contains the best ratio of keywords per total of words, other sections of the article may be a better source of biologically relevant data.

    2013-01-01

    This study examined the 2 preventive medicine journals in North Korea by using coauthor and keyword network analysis on the basis of medical informatics and bibliometrics. Used were the Journal of Chosun Medicine (JCM) and the Journal of Preventive Medicine (JPM) (from the first volume of 1997 to the fourth volume of 2006) as data. Extracted were 1734 coauthors from 1104 articles and 1567 coauthors from 1172 articles, respectively. Huge single components were extracted in the coauthor analysis, which indicated a tendency toward structuralization. However, the 2 journals differed in that JPM showed a relative tendency toward specialization, whereas JCM showed one toward generalization. Seventeen and 33 keywords were extracted from each journal in the keyword analysis; JCM mainly concerned pathological research, whereas JPM mainly concerned virus and basic medicine studies that were based on infection and immunity. In contrast to South Korea, North Korea has developed Juche medicine, which came from self-reliance ideology and gratuitous medical service. According to the present study, their ideology was embodied by the discovery of bacteria, study on immune system, and emphasis on pathology, on the basis of experimental epidemiology. However, insufficient research has been conducted thus far on population health and its related determinants.

    Since current general interest in anesthesia is unknown, we analyzed internet keyword searches to gauge general interest in anesthesia in comparison with surgery and pain. The trend of keyword searches from 2004 to 2010 related to anesthesia and anaesthesia was investigated using Google Insights for Search. The trend of number of peer reviewed articles on anesthesia cited on PubMed and Medline from 2004 to 2010 was investigated. The average cost on advertising on anesthesia, surgery and pain was estimated using Google AdWords. Searching results in other common search engines were also analyzed. Correlation between year and relative number of searches was determined with psearch engines may provide different total number of searching results (available posts), the ratios of searching results between some common keywords related to perioperative care are comparable, indicating similar trend. The peer reviewed manuscripts on "anesthesia" and the proportion of papers on "anesthesia and outcome" are trending up. Estimates for spending of advertising dollars are less for anesthesia-related terms when compared to that for pain or surgery due to relative smaller number of searching traffic. General interest in anesthesia (anaesthesia) as measured by internet searches appears to be decreasing. Pain, preanesthesia evaluation, anesthesia and outcome and side effects of anesthesia are the critical areas that anesthesiologists should focus on to address the increasing concerns.

    Full Text Available The ever-increasing quantities of digital photo resources are annotated with enriching vocabularies to form semantic annotations. Photo-sharing social networks have boosted the need for efficient and intuitive querying to respond to user requirements in large-scale image collections. In order to help users formulate efficient and effective image retrieval, we present a novel integration of a probabilistic model based on keyword query architecture that models the probability distribution of image annotations: allowing users to obtain satisfactory results from image retrieval via the integration of multiple annotations. We focus on the annotation integration step in order to specify the meaning of each image annotation, thus leading to the most representative annotations of the intent of a keyword search. For this demonstration, we show how a probabilistic model has been integrated to semantic annotations to allow users to intuitively define explicit and precise keyword queries in order to retrieve satisfactory image results distributed in heterogeneous large data sources. Our experiments on SBU (collected by Stony Brook University database show that (i our integrated annotation contains higher quality representatives and semantic matches; and (ii the results indicating annotation integration can indeed improve image search result quality.

  1. Using Gazetteers to Extract Sets of Keywords from Free-Flowing Texts

    Full Text Available If you have a copy of a text in electronic format stored on your computer, it is relatively easy to keyword search for a single term. Often you can do this by using the built-in search features in your favourite text editor. However, scholars are increasingly needing to find instances of many terms within a text or texts. For example, a scholar may want to use a gazetteer to extract all mentions of English placenames within a collection of texts so that those places can later be plotted on a map. Alternatively, they may want to extract all male given names, all pronouns, stop words, or any other set of words. Using those same built-in search features to achieve this more complex goal is time consuming and clunky. This lesson will teach you how to use Python to extract a set of keywords very quickly and systematically from a set of texts. It is expected that once you have completed this lesson, you will be able to generalise the skills to extract custom sets of keywords from any set of locally saved files.

  2. An Interval Estimation Method of Patent Keyword Data for Sustainable Technology Forecasting

    Full Text Available Technology forecasting (TF is forecasting the future state of a technology. It is exciting to know the future of technologies, because technology changes the way we live and enhances the quality of our lives. In particular, TF is an important area in the management of technology (MOT for R&D strategy and new product development. Consequently, there are many studies on TF. Patent analysis is one method of TF because patents contain substantial information regarding developed technology. The conventional methods of patent analysis are based on quantitative approaches such as statistics and machine learning. The most traditional TF methods based on patent analysis have a common problem. It is the sparsity of patent keyword data structured from collected patent documents. After preprocessing with text mining techniques, most frequencies of technological keywords in patent data have values of zero. This problem creates a disadvantage for the performance of TF, and we have trouble analyzing patent keyword data. To solve this problem, we propose an interval estimation method (IEM. Using an adjusted Wald confidence interval called the Agresti–Coull confidence interval, we construct our IEM for efficient TF. In addition, we apply the proposed method to forecast the technology of an innovative company. To show how our work can be applied in the real domain, we conduct a case study using Apple technology.

    Many types of medical errors occur in and outside of hospitals, some of which have very serious consequences and increase cost. Identifying errors is a critical step for managing and preventing them. In this study, we assessed the explicit reporting of medical errors in the electronic record. We used five search terms "mistake," "error," "incorrect," "inadvertent," and "iatrogenic" to survey several sets of narrative reports including discharge summaries, sign-out notes, and outpatient notes from 1991 to 2000. We manually reviewed all the positive cases and identified them based on the reporting of physicians. We identified 222 explicitly reported medical errors. The positive predictive value varied with different keywords. In general, the positive predictive value for each keyword was low, ranging from 3.4 to 24.4%. Therapeutic-related errors were the most common reported errors and these reported therapeutic-related errors were mainly medication errors. Keyword searches combined with manual review indicated some medical errors that were reported in medical records. It had a low sensitivity and a moderate positive predictive value, which varied by search term. Physicians were most likely to record errors in the Hospital Course and History of Present Illness sections of discharge summaries. The reported errors in medical records covered a broad range and were related to several types of care providers as well as non-health care professionals.

    2016-01-01

    Full Text Available With the development of cloud computing, more and more data owners are motivated to outsource their data to the cloud server for great flexibility and less saving expenditure. Because the security of outsourced data must be guaranteed, some encryption methods should be used which obsoletes traditional data utilization based on plaintext, e.g. keyword search. To solve the search of encrypted data, some schemes were proposed to solve the search of encrypted data, e.g. top-k single or multiple keywords retrieval. However, the efficiency of these proposed schemes is not high enough to be impractical in the cloud computing. In this paper, we propose a new scheme based on homomorphic encryption to solve this challenging problem of privacy-preserving efficient multi-keyword ranked search over outsourced cloud data. In our scheme, the inner product is adopted to measure the relevance scores and the technique of relevance feedback is used to reflect the search preference of the data users. Security analysis shows that the proposed scheme can meet strict privacy requirements for such a secure cloud data utilization system. Performance evaluation demonstrates that the proposed scheme can achieve low overhead on both computation and communication.

    The significant influence of the number and position of fish sperm sample straws in uncontrolled cooling devices on post-thaw spermatozoa parameters, such as motility and fertilizing ability, is presented in this study. The two most popular uncontrolled cooling devices were used in this study: a Styrofoam box setup with a polystyrene floating raft on liquid nitrogen and the dry shipper setup with a straw holder. We tested the effect of different quantities of straws (6 or 60) placed on the polystyrene floating raft and the position of the straws in the holder (on the periphery or in the centre). Using these cooling methods, sperm of 10 male sterlets diluted with methanol containing cryoprotective medium was frozen. All temperature changes were recorded by a thermocouple inside the straw, and the thermogram intervals were analysed. Spermatozoa motility was evaluated by video microscopy with integrated computer-assisted sperm analysis software. Fertilization trials were conducted at a 10 5 spermatozoa/egg ratio. Post-thaw spermatozoa parameters, including the percent of motile spermatozoa, curvilinear velocity, velocity according to the smoothed path, linearity of track, beat-cross frequency and fertilization rate, were significantly decreased in the 60-straw floating raft setup in comparison to all of the other cooling methods. The freezing rate between -10 °C and -30 °C was significantly decreased by up to 18.6 ± 0.61 °C/min for the 60-straw floating raft setup in comparison to the other freezing conditions. Considering the above results, efforts to standardize cryopreservation protocols using uncontrolled cooling devices should take into account the amount of straws subjected to freezing.

    2013-04-01

    Full Text Available BACKGROUND: Advanced glycation end products (AGE and their receptor (RAGE system play an important role in the development of diabetic vascular complications. Recently, an endogenous secretory RAGE (esRAGE has been identified as a novel splice variant, which lacks the transmembrane domain and is secreted in human sera. Interestingly, it was reported that esRAGE binds AGE ligands and neutralizes AGE actions. Many studies have reported that diabetes mellitus correlates with vascular calcification event and increases progressively in uncontrolled diabetes. Matrix Gla Protein (MGP is known to act as an inhibitor in vascular calcification. The aim of this study was to observe progress of vascular calcification in uncontrolled diabetes patient by biochemical markers MGP as inhibitor in vascular calcification, via mechanism of AGEs. METHODS: This study was an observational study with cross sectional design on adult type 2 diabetic male patients who were defined by the 2011 Indonesian diabetes mellitus consensus criteria. RESULTS: The results of this study showed that there was a positive significant correlation between esRAGE and HbA1C (r=0.651, p=0.009, and negative correlation between MGP and HbA1C (r=-0.465, p=0.081 in controlled diabetes group. In uncontrolled diabetes group there was a positive significant correlation between MGP and HbA1C (r=0.350, p=0.023, despite the fact esRAGE showed no significant correlation with HbA1C. There was no significant difference in level of esRAGE and MGP in controlled and uncontrolled diabetes group, but MGP showed lower level in uncontrolled diabetes group, contrary to esRAGE that had higher concentration. CONCLUSIONS: In diabetes condition, complications of vascular calcification are caused by the mechanism of increased AGE formation represented by esRAGE. In diabetes control it is very important to keep the blood vessels from complications caused by vascular calcification. KEYWORDS: type 2 diabetes mellitus

    Full Text Available Continuous changes in technology, economic, social and psychological understandings and structures have influence on both Human Resources and their management. Organizations approach their human capital in a more sensitive way in order to win the loyalty and commitment of them, while increasing profit and maximizing the efficiency/effectiveness of its work power. Human Resources Management helps achieving these goals by recruiting, training, developing, motivating and rewarding employees. Therefore, the identification of current research interests is essential to lead them in defining organizational human resources strategies. The main purpose of this research is to identify top rated factors related to Human Resource Management by analyzing all the abstracts of the published papers in a Human Resource Management journal from the beginning of 2005 till the end of 2012. As a result of analyzing the keywords of all abstracts, the frequencies of the keyword categories are identified. Except the keywords related to Human Resources (17.6%, it is observed that the studies for the period consider the following: Employee rights and their career (18.3%, management (14.6%, contextual issues (10%, organizational strategies (9.5%, performance measurement and training (9.5%, behavioral issues and employee motivation (5.7, organizational culture (5.4%, technical issues (4.1%, etc. It should be noted that the researchers (a mainly stress on practice more than theory and (b consider the organization less than the individual. Interestingly, employee motivation is found to be less considered by the researchers. This study is believed to be useful for future studies and the industry by identifying the hot and top rated factors related to Human Resource Management.

    BACKGROUND: Asthma is a common chronic disease among young adults, and several studies have reported increased mortality rates in patients with asthma. However, no study has described sudden unexpected death in a nationwide setting in patients with uncontrolled asthma. We defined uncontrolled...... asthma as a previous hospital admittance because of asthma (of any severity) or when asthma was considered to have influenced the death according to the death certificate. The purpose of this study is to increase the medical focus on young persons with uncontrolled asthma and thereby hopefully aid...... in preventing sudden unexpected deaths. We therefore aimed to describe clinical characteristics, symptoms, causes of death, and contact with the healthcare system prior to sudden unexpected death in young persons with uncontrolled asthma. METHODS: Through the review of death certificates, we found 625 sudden...

    Lowering blood pressure reduces cardiovascular risk, yet hypertension is poorly controlled in diabetic patients. In a pilot study we demonstrated that a home blood pressure telemonitoring system, which provided self-care messages on the smartphone of hypertensive diabetic patients immediately after each reading, improved blood pressure control. Messages were based on care paths defined by running averages of transmitted readings. The present study tests the system's effectiveness in a randomized, controlled trial in diabetic patients with uncontrolled systolic hypertension. Of 244 subjects screened for eligibility, 110 (45%) were randomly allocated to the intervention (n = 55) or control (n = 55) group, and 105 (95.5%) completed the 1-year outcome visit. In the intention-to-treat analysis, mean daytime ambulatory systolic blood pressure, the primary end point, decreased significantly only in the intervention group by 9.1 ± 15.6 mmHg (SD; P blood pressure telemonitoring combined with automated self-care support reduced the blood pressure of diabetic patients with uncontrolled systolic hypertension and improved hypertension control. Home blood pressure monitoring alone had no effect on blood pressure. Promoting patient self-care may have negative psychological effects.

    Recent advances in high-throughput methods and the application of computational tools for automatic classification of proteins have made it possible to carry out large-scale proteomic analyses. Biological analysis and interpretation of sets of proteins is a time-consuming undertaking carried out manually by experts. We have developed PANDORA (Protein ANnotation Diagram ORiented Analysis), a web-based tool that provides an automatic representation of the biological knowledge associated with any set of proteins. PANDORA uses a unique approach of keyword-based graphical analysis that focuses on detecting subsets of proteins that share unique biological properties and the intersections of such sets. PANDORA currently supports SwissProt keywords, NCBI Taxonomy, InterPro entries and the hierarchical classification terms from ENZYME, SCOP and GO databases. The integrated study of several annotation sources simultaneously allows a representation of biological relations of structure, function, cellular location, taxonomy, domains and motifs. PANDORA is also integrated into the ProtoNet system, thus allowing testing thousands of automatically generated clusters. We illustrate how PANDORA enhances the biological understanding of large, non-uniform sets of proteins originating from experimental and computational sources, without the need for prior biological knowledge on individual proteins.

    1993-08-01

    In order to investigate the cognitive processes involved in learning Foreign Language (FL) vocabulary, this study evaluates different methods of instruction. It demonstrates that keyword techniques are effective for receptive learning but that repetition is a superior strategy for learning to produce the foreign word. Performance is optimal when learners combine both strategies. The nature of the keyword is crucial--whereas imageable noun keywords promote learning, verb keywords actually impede it. A theoretical analysis of the roles of phonological short-term memory, imagery, and lexical factors in FL vocabulary learning is presented.

    Full Text Available What language should be featured in assessment standards for international students? Have universities adjusted their assessment methods sufficiently to match the increased demand for studying abroad? How might art and design benefit from a more stable definition of standards? These are some questions this paper seeks to address by reporting the results of recent pedagogic research at the School of the Arts, Loughborough University, in the United Kingdom. Language use is at the heart of this issue, yet it is generally overlooked as an essential tool that links assessment, feedback and action planning for international students. The paper reveals existing and new data that builds on research since 2009, aimed at improving students’ assessment literacy. Recommendations are offered to stimulate local and global discussion about keyword use for defining undergraduate assessment standards in art and design.

    Full Text Available The issue of sustainability is a vital long-term goal for organizations and as such has formed the basis of much academic research over the last two decades. Organizational sustainability is defined as the ability for an organization to accomplish a range of economic, environmental, and human performance objectives. As one of the most studied topics in organizational science, employee engagement at work is seen as a critical component to achieving sustainable organizational success. In order to better understand the employee engagement discourse, this study examined the keywords that appear in the titles and abstract of the employee engagement research domain using the burst detection and social network analysis techniques. A total of 1406 employee engagement relevant articles that were published from 1990 to 2015 were included and investigated in the study. The results revealed the fading, emerging, and central themes within the employee engagement domain.

  4. A Privacy-Preserving Intelligent Medical Diagnosis System Based on Oblivious Keyword Search

    2017-01-01

    Full Text Available One of the concerns people have is how to get the diagnosis online without privacy being jeopardized. In this paper, we propose a privacy-preserving intelligent medical diagnosis system (IMDS, which can efficiently solve the problem. In IMDS, users submit their health examination parameters to the server in a protected form; this submitting process is based on Paillier cryptosystem and will not reveal any information about their data. And then the server retrieves the most likely disease (or multiple diseases from the database and returns it to the users. In the above search process, we use the oblivious keyword search (OKS as a basic framework, which makes the server maintain the computational ability but cannot learn any personal information over the data of users. Besides, this paper also provides a preprocessing method for data stored in the server, to make our protocol more efficient.

    Data outsourcing services have emerged with the increasing use of digital information. They can be used to store data from various devices via networks that are easy to access. Unlike existing removable storage systems, storage outsourcing is available to many users because it has no storage limit and does not require a local storage medium. However, the reliability of storage outsourcing has become an important topic because many users employ it to store large volumes of data. To protect against unethical administrators and attackers, a variety of cryptography systems are used, such as searchable encryption and proxy reencryption. However, existing searchable encryption technology is inconvenient for use in storage outsourcing environments where users upload their data to be shared with others as necessary. In addition, some existing schemes are vulnerable to collusion attacks and have computing cost inefficiencies. In this paper, we analyze existing proxy re-encryption with keyword search.

In this paper, we present a new similarity-based multi-keyword search scheme for encrypted data. This scheme provides high flexibility in the pre- and post-processing of encrypted data, including splitting stem/suffix and computing from the encrypted index-term matrix, demonstrated to support Latent Semantic Indexing(LSI. On the client side, the computation and communication costs are one to two orders of magnitude lower than those of previous methods, as demonstrated in the experimental results. we also provide a security analysis of the proposed scheme.

  7. A step beyond simple keyword searches: Services enabled by a full content digital journal archive

    Boccippio, D. J.

    2003-12-01

    The problems of managing and searching large archives of scientific journal articles can potentially be addressed through data mining and statistical techniques matured primarily for quantitative scientific data analysis. A journal paper could be represented by a multivariate descriptor, e.g., the occurrence counts of a number key technical terms or phrases (keywords), perhaps derived from a controlled vocabulary (e.g., the American Meteorological Society's Glossary of Meteorology) or bootstrapped from the journal archive itself. With this technique, conventional statistical classification tools can be leveraged to address challenges faced by both scientists and professional societies in knowledge management. For example, cluster analyses can be used to find bundles of "most-related" papers, and address the issue of journal bifurcation (when is a new journal necessary, and what topics should it encompass). Similarly, neural networks can be trained to predict the optimal journal (within a society's collection) in which a newly submitted paper should be published. Comparable techniques could enable very powerful end-user tools, all premised on the view of a paper as a data point in a multidimensional descriptor space, e.g.: "find papers most similar to the one I am reading", "build a personalized subscription service, based on the content of the papers I am interested in, rather than preselected keywords", "find suitable reviewers, based on the content of their own published works", etc. Such services may represent the next "quantum leap" beyond the rudimentary search interfaces currently provided to end-users, as well as a compelling value-added component needed to help bridge the print-to-digital-medium gap, and help stabilize professional societies' revenue stream during the print-to-digital transition.

    Despite the availability of numerous antiepileptic drugs (AEDs), some epilepsies remain resistant to treatment. We compared utilization and costs in patients with uncontrolled epilepsy to those with stable epilepsy. Claims data (2007-2009) were used to identify adults with epilepsy requiring additional AED therapy (having uncontrolled epilepsy) and those not requiring additional AED therapy (having stable epilepsy). The date in 2008 on which an additional AED was started was the index date for patients with uncontrolled epilepsy, and a randomly selected date was used for patients with stable epilepsy, whose AED use was unchanged in the preceding year. In the postindex year, all pharmacy and medical claims were used to estimate overall utilization and costs; claims with epilepsy in any diagnosis field were used to estimate epilepsy-related outcomes. Outcomes were adjusted using multivariate analyses. We identified 1536 patients with uncontrolled epilepsy and 8571 patients with stable epilepsy (mean age: 42.8years; female: 48%). Patients with uncontrolled epilepsy had higher comorbidity rates (pepilepsy had ≥1 hospitalization or emergency department visit (pepilepsy had a greater mean length of hospital stay and more physician office visits (pepilepsy-related) and emergency department visit (OR: 1.6, any diagnosis; 1.9, epilepsy-related) were greater for patients with uncontrolled epilepsy. Annual overall ($23,238 vs. $13,839) and epilepsy-related ($12,399 vs. $5511) costs were higher in patients with uncontrolled epilepsy and remained higher after adjustment (pepilepsy use more services and incur higher costs compared with those with stable epilepsy. Epilepsy-related costs accounted for <50% of the total costs, suggesting that comorbid conditions and/or underidentification of utilization may substantially contribute to costs. © 2013.

    To investigate whether vildagliptin add-on insulin therapy improves glycemic variations in patients with uncontrolled type 2 diabetes (T2D) compared to patients with placebo therapy. This was a 24-week, single-center, double-blind, placebo-controlled trial. Inadequately controlled T2D patients treated with insulin therapy were recruited between June 2012 and April 2013. The trial included a 2-week screening period and a 24-week randomized period. Subjects were randomly assigned to a vildagliptin add-on insulin therapy group (n = 17) or a matched placebo group (n = 16). Scheduled visits occurred at weeks 4, 8, 12, 16, 20, and 24. Continuous glucose monitoring (CGM) was performed before and at the endpoint of the study. A total of 33 subjects were admitted, with 1 patient withdrawing from the placebo group. After 24 weeks of therapy, HbA1c values were significantly reduced at the endpoint in the vildagliptin add-on group. CGM data showed that patients with vildagliptin add-on therapy had a significantly lower 24-h mean glucose concentration and mean amplitude of glycemic excursion (MAGE). At the endpoint of the study, patients in the vildagliptin add-on group had a significantly lower MAGE and standard deviation compared to the control patients during the nocturnal period (0000-0600). A severe hypoglycemic episode was not observed in either group. Vildagliptin add-on therapy to insulin has the ability to improve glycemic variations, especially during the nocturnal time period, in patients with uncontrolled T2D.

    Progressive burden of diabetes mellitus is a major concern in India. Data on the predictors of poor glycemic control among diabetics are scanty. A population-based cross-sectional study nested in an urban cohort was thus conducted in West Bengal, India to determine the burden and correlates of total and uncontrolled abnormalities in glucose metabolism (AGM) in a representative population. From 9046 adult cohort-members, 269 randomly selected consenting subjects (non-response = 7.24%) were interviewed, examined [blood pressure (BP), anthropometry], tested for fasting plasma glucose (FPG) and glycosylated hemoglobin (HbA1C). Those having pre-diagnosed diabetes or FPG ≥126 or HbA1c≥6.5 were defined as diabetic. Among non-diabetics, subjects with FPG (mg/dl) = 100-125 or HbA1C(%) = 5.7-6.4 were defined as pre-diabetic. Pre-diagnosed cases with current FPG ≥126 were defined as uncontrolled AGM. Descriptive and regression analyses were conducted using SAS-9.3.2. Among participants, 28.62% [95% Confidence Interval (95%CI) = 23.19-34.06)] were overweight [body mass index(BMI) = (25-29.99)kg/meter2], 7.81% (4.58-11.03) were obese(BMI≥30kg/meter2), 20.82% (15.93-25.70) were current smokers, 12.64% (8.64-16.64) were current alcohol-drinkers and 46.32% of responders (39.16-53.47) had family history of diabetes. 17.84% (13.24-22.45) had stage-I [140≤average systolic BP (AvSBP in mm of mercury)urban India should include interventions targeting appropriate diabetic control among relatively older persons, unemployed, business-owners, retired, ex-smokers, ex-drinkers and hypertensives.

    Full Text Available African Americans and Hispanics have disproportionate rates of uncontrolled essential hypertension (EH compared to Non-Hispanic Whites. Medication non-adherence (MNA is the leading modifiable behavior to improved blood pressure (BP control. The Smartphone Medication Adherence Stops Hypertension (SMASH program was developed using a patient-centered, theory-guided, iterative design process. Electronic medication trays provided reminder signals, and Short Message Service [SMS] messaging reminded subjects to monitor BP with Bluetooth-enabled monitors. Motivational and reinforcement text messages were sent to participants based upon levels of adherence. Thirty-eight African-American (18 and Hispanic (20 uncontrolled hypertensives completed clinic-based anthropometric and resting BP evaluations prior to randomization, and again at months 1, 3 and 6. Generalized linear mixed modeling (GLMM revealed statistically significant time-by-treatment interactions (p < 0.0001 indicating significant reductions in resting systolic blood pressure (SBP and diastolic blood pressure (DBP for the SMASH group vs. the standard care (SC control group across all time points. 70.6% of SMASH subjects vs. 15.8% of the SC group reached BP control (< 140/90 mmH at month 1 (p < 0.001. At month 6, 94.4% of the SMASH vs. 41.2% of the SC group exhibited controlled BP (p < 0.003. Our findings provide encouraging evidence that efficacious mHealth, chronic disease, medical regimen, self-management programs can be developed following principles of patient-centered, theory-guided design.

    The present study was designed to evaluate the associations between sleep duration and uncontrolled blood pressure in a hospital-based sample of middle-aged adults. Between March 2012 and December 2012, a cross-sectional survey was conducted among the hypertensive outpatients of Anzhen Hospital and a community hospital in Beijing, China. Eligible participants were adults aged 35-55 years with an established diagnosis of hypertension and had been on standard antihypertensive drug treatment for at least 6 months. An interviewer-led questionnaire was used to collect the participants' demographic, lifestyle and dietary information, as well as medical histories. Usual sleep durations were categorized as 8 h per night. Logistic regression models were used to assess gender-specific associations between sleep duration and uncontrolled hypertension, with adjustment for age, gender, family history, diabetes, smoking, alcohol consumption and physical activity. A total of 3038 participants were finally investigated. Among them, 1569 (51.6%) patients had their blood pressure uncontrolled. In men, no significant association was found between sleep duration categories and uncontrolled hypertension. In women, compared with those sleeping sleeping 7-8 hours (odds ratio [OR] 0.537, 95% confidence interval [CI], 0.370-0.780) and sleeping >8 h (OR 0.316, 95% CI, 0.202-0.494), respectively. Modest associations between short sleep duration and uncontrolled hypertension were seen in middle-aged women but not in men in the hypertensive population.

    The prevalence and associated factors of untreated, uncontrolled, and apparent-resistant hypertension (RH) in Germany are unknown. Based on European Society of Hypertension criteria, apparent RH was defined as blood pressure (BP) ≥140/90 mm Hg (≥140/85 mm Hg in diabetics) under treatment with three different classes of antihypertensive agents including a diuretic. Data from the German Health Examination Survey (2008-2011; n=7115, age 18-79 years) including standardized BP measurements and Anatomical Therapeutic Chemical-coded taken medications were analyzed. Among patients aware of their hypertensive status (n=2205), 37.9% were uncontrolled and, among those, 33.4% were untreated. Being aware and having untreated and uncontrolled BP was associated with male sex, young age, not having cardiovascular disease, not performing BP self-measurement, not being obese, and not smoking. Apparent RH occurred in 6.8% of treated aware hypertensive patients and was positively associated with having diabetes. The proportion of uncontrolled BP is still high. Not having "obvious risk factors" has become a risk itself for having untreated and uncontrolled hypertension. ©2016 Wiley Periodicals, Inc.

    We studied whether the origins of math anxiety can be related to a biologically supported framework of stress induction: (un)controllability perception, here indicated by self-reported independent efforts in mathematics. Math anxiety was tested in 182 children (8- to 11-year-olds). Latent factor modeling was used to test hypotheses on plausible causal processes and mediations within competing models in quasi-experimental contrasts. Uncontrollability perception in mathematics, or (in)dependence of efforts, best fit the data as an antecedent of math anxiety. In addition, the relationship of math anxiety with gender was fully mediated by adaptive perception of control (i.e. controllability). That is, young boys differ from girls in terms of their experience of control in mathematics learning. These differences influence math anxiety. Our findings are consistent with recent suggestions in clinical literature according to which uncontrollability makes women more susceptible to fear and anxiety disorders. © 2014 John Wiley & Sons Ltd.

  20. Uncontrolled manifold reference feedback control of multi-joint robot arms

    Full Text Available The brain must coordinate with redundant bodies to perform motion tasks. The aim of the present study is to propose a novel control model that predicts the characteristics of human joint coordination at a behavioral level. To evaluate the joint coordination, an uncontrolled manifold (UCM analysis that focuses on the trial-to-trial variance of joints has been proposed. The UCM is a nonlinear manifold associated with redundant kinematics. In this study, we directly applied the notion of the UCM to our proposed control model called the UCM reference feedback control. To simplify the problem, the present study considered how the redundant joints were controlled to regulate a given target hand position. We considered a conventional method that pre-determined a unique target joint trajectory by inverse kinematics or any other optimization method. In contrast, our proposed control method generates a UCM as a control target at each time step. The target UCM is a subspace of joint angles whose variability does not affect the hand position. The joint combination in the target UCM is then selected so as to minimize the cost function, which consisted of the joint torque and torque change. To examine whether the proposed method could reproduce human-like joint coordination, we conducted simulation and measurement experiments. In the simulation experiments, a three-link arm with a shoulder, elbow, and wrist regulates a one-dimensional target of a hand through proposed method. In the measurement experiments, subjects performed a one-dimensional target-tracking task. The kinematics, dynamics, and joint coordination were quantitatively compared with the simulation data of the proposed method. As a result, the UCM reference feedback control could quantitatively reproduce the difference of the mean value for the end hand position between the initial postures, the peaks of the bell-shape tangential hand velocity, the sum of the squared torque, the mean value for

  2. Gender, cancer experience and internet use: a comparative keyword analysis of interviews and online cancer support groups.

    A new method, comparative keyword analysis, is used to compare the language of men and women with cancer in 97 research interviews and two popular internet based support groups for people with cancer. The method is suited to the conjoint qualitative and quantitative analysis of differences between large bodies of text, an alternative to the 'code and retrieval' approach used in much thematic analysis of qualitative materials. Web forums are a rich source of data about illness experience and gender differences. Marked differences in the performance of gender are evident. These differences follow linguistic and other behavioural patterns (such as social network differences) established in other contexts. Men with prostate cancer indicate in research interviews that they are more likely to seek information on the internet; women with breast cancer that they are more likely to seek social and emotional support. Men's concerns cluster around treatment information, medical personnel and procedures. Their experience of disease is more localised on particular areas of the body, while women's experience is more holistic. Women's forum postings orientate much more towards the exchange of emotional support, including concern with the impact of illness on a wide range of other people. Women's use of superlatives as well as words referring to feelings indicate their enactment of greater emotional expressivity. Web forums are platforms for an intensification of men's knowledge gathering activities. Web forums, though actually quite publicly visible, appear to be subjectively experienced by both sexes as relatively private places for the exchange of intimate personal information. The 'privacy' of the breast cancer forum facilitated interactions found in other studies to be characteristic of women's friendship groups.

    The online speech-in-noise test 'Earcheck' is sensitive for noise-induced hearing loss (NIHL). This study investigates effects of uncontrollable parameters in domestic self-screening, such as presentation level and transducer type, on speech reception thresholds (SRTs) obtained with Earcheck. Subjects performed 26 Earchecks that differed regarding presentation level (65, 71, and 77 dBA), presentation mode (monotic or diotic), and masking noise (two different low-pass filtered noises) in the lab. To investigate effects of test environment, participants conducted eight additional Earchecks at home using different transducer types (headphones or loudspeakers). Thirty noise-exposed workers, either normal-hearing (n = 10), or with different degrees of NIHL (n = 20), participated. There was a minor effect of presentation levels exceeding 65 dBA in severely impaired listeners. Diotic presentation mode yielded lower SRTs compared to monotic presentation mode. Normal-hearing test results at home were poorer than in the laboratory, whereas hearing-impaired subjects performed better in domestic testing. Using loudspeakers deteriorated SRTs significantly in comparison to headphones, but only in hearing-impaired subjects. A monotic presentation mode using headphones is recommended for domestic screening. Since domestic testing affects SRT results, a follow up study using a large study population should assess Earcheck's validity when performed at home.

    Approximately 17% of Canadians with high blood pressure were unaware of their condition, and of Canadians aware of having the condition, approximately 1 in 5 have uncontrolled high blood pressure despite high rates of pharmacotherapy. The objectives of the current study are to estimate the prevalence of resistant hypertension and examine factors associated with (1) lack of awareness and (2) uncontrolled hypertension despite pharmacotherapy. Using the 2007-2009 Canadian Health Measures Survey (N = 3473, aged 20-79 years) and logistic regression, we quantified relationships between characteristics and (1) presence of hypertension, (2) lack of awareness (among those with hypertension), and (3) uncontrolled high blood pressure (among those treated for hypertension). Older age, lowest income, and less than high school education were associated with presence of hypertension. Men (odds ratio [OR], 1.6; 95% confidence interval [CI], 1.1-2.2) and adults high blood pressure (OR, 2.4; 95% CI, 1.1-5.2) despite treatment. Elevated systolic blood pressure was the issue in over 90% of women and 80% of men with uncontrolled hypertension. Depending on the definition employed, 4.4% (95% CI, 2.4-6.4) to 7.8% (95% CI, 6.0-9.6) of the population with hypertension had resistant hypertension. Messaging or interventions encouraging screening may be helpful for all younger Canadian adults and men; programs encouraging blood pressure control may help older women.

    Numerous studies with compelling evidence had shown a clear relationship between dyslipidaemia and cardiovascular (CV) events in patients with diabetes mellitus. This was an observational study based on secondary data from the online registry database Adult Diabetes Control and Management (ADCM) looking into the determinants of uncontrolled dyslipidaemia in type 2 diabetes mellitus patients. Independent predictors were identified using multivariate logistic regression. A total of 303 centres (289 health clinics, 14 hospitals) contributed a total of 70,889 patients (1972 or 2.8% patients were from hospital). About thirty eight percent were reported to have dyslipidaemia. There were 40.7% patients on lipid-lowering agents and of those above age 40 years old, only 38.1% of them were on a statin. Malay ethnicity and younger age groups (<50 years old) were two major determinants of uncontrolled LDL-C, TG and HDL-C. Female gender and uncontrolled blood pressure were determinants of uncontrolled LDL-C, and poor glycaemic control was related independently to high TG. This study has highlighted the suboptimal management of diabetic dyslipidaemia in Malaysia. Pharmacological treatment of dyslipidaemia could be more effective. Healthcare stakeholders in this country, especially in the primary care, have to recognize these shortfalls and take immediate remedial measures. Copyright © 2012 Elsevier Ireland Ltd.

    According to learned helplessness theory, uncontrollable stress is assumed to be a critical etiological factor in the pathogenesis of depression. In contrast, unpredictability of stressors is assumed to facilitate the development of sustained anxiety. Despite the frequent co-morbidity of depression and anxiety disorders, these two factors have rarely been studied simultaneously in humans. Therefore, we investigated whether there are interaction effects of uncontrollability and unpredictability on anxiety response in healthy participants. Seventy-nine healthy participants performed a visual dot probe task with emotional faces, while receiving mild electrical shocks in four different conditions (2 × 2 factorial design). In (un)controllable conditions, participants were (not) able to attenuate shock intensity. In (un)predictable conditions, participants were (not) able to anticipate shock occurrence. Before the experiment, participants' subclinical depression and anxiety scores were measured using the Beck Depression and Anxiety Inventories (BDI/BAI). During the experiment, continuous skin conductance and self-reported state anxiety were assessed and attentional biases towards angry faces were calculated. As expected, participants showed greater anxiety in uncontrollable compared to controllable and in unpredictable compared to predictable conditions. Additionally, anxiety decreased within the test sessions in participants with low BDI/BAI scores but not in participants with higher BDI/BAI scores. Most importantly, controllability and predictability interacted with each other and with BDI/BAI scores with regard to anxiety. Our results provide evidence that uncontrollability and unpredictability of stressors not only have separate but also interaction effects on several anxiety measures in susceptible individuals and may provide insights into the psychological mechanisms underlying a depressive/anxiety co-morbidity.

    Severe persistent asthma is often poorly controlled and its prevalence in pneumology and allergy hospital units in Spain is unknown. To determine the prevalence of uncontrolled severe persistent asthma in hospital units in Spain and to describe the clinical characteristics of this condition. An observational, cross-sectional study was conducted in 164 Spanish hospital pneumology and allergology units. A record was made of all patients with asthma and patients with uncontrolled severe asthma (diagnosed on the basis of clinical criteria) seen in these units over 6 months. Information on sociodemographic variables, clinical characteristics, pharmacological asthma treatment, skin prick testing, total serum immunoglobulin E (IgE) levels, pulmonary function (forced expiratory volume in the first second and forced vital capacity), asthma control (Asthma Control Questionnaire [ACQ]), and quality of life (Asthma Quality of Life Questionnaire) was collected. According to the clinicians' judgement, 1423 out of 36 649 asthma patients (3.9%, 95% confidence interval, 3.7%-4.1%]) had uncontrolled severe persistent asthma.These patients had a mean (SD) ACQ score of 3.8 (1.0); 55.8% had a positive skin prick test to common aeroallergens and 54.2% had high levels of total serum IgE.The agreement between the assessment of asthma control based on clinicians' criteria and according to the Global Initiative forAsthma (GINA) guidelines was moderate (63.2%, Kic = 0.337), with an underestimation of asthma severity by clinicians; 53.2% of the patients classified as having controlled moderate to severe asthma had uncontrolled severe persistent asthma according to GINA criteria. There is a low prevalence of uncontrolled severe persistent asthma in patients seen at hospital units in Spain according to clinical criteria, although it should be noted that level of asthma control is overestimated by clinicians.

    Research on eating behaviour has identified several potentially relevant eating-related traits captured by different questionnaires. Often, these questionnaires predict Body Mass Index (BMI), but the relationship between them has not been explicitly studied. We studied the unity and diversity of questionnaires capturing five common eating-related traits: Power of Food, Eating Impulsivity, emotional eating, Disinhibition, and binge eating in women from Estonia (n = 740) and Canada (n = 456). Using bifactor analysis, we showed that a) these questionnaires are largely explained by a single factor, and b) relative to this shared factor, only some questionnaires offered additional variance in predicting BMI. Hence, these questionnaires seemed to characterise a common factor, which we label Uncontrolled Eating. Item Response Theory techniques were then applied to demonstrate that c) within this common factor, the questionnaires could be placed on a continuum of Uncontrolled Eating. That is, Eating Impulsivity focused on the milder degree, Power of Food Scale, emotional eating scales, and Disinhibition on intermediate degrees, and the Binge Eating Scale on the most severe degrees of Uncontrolled Eating. In sum, evidence from two samples showed that questionnaires capturing five common BMI-related traits largely reflected the same underlying latent trait - Uncontrolled Eating. In Estonia, some questionnaires focused on different severities of this common construct, supporting a continuum model of Uncontrolled Eating. These findings provide a starting point for developing better questionnaires of the neurobehavioural correlates of obesity, and provide a unifying perspective from which to view the existing literature.

    2014-01-01

    In medical and psychological literature bulimia is commonly described as a mental illness. However, from a social constructionist perspective the meaning of bulimia will always be socially and historically situated and multiple. Thus, there is always the possibility for other understandings or constructions of bulimia to circulate in our culture, with each having distinct real-world implications for those engaging in bulimic behaviors; for instance, they might potentially influence likelihood of help-seeking and the success of treatment. This study used Q methodology to explore culturally-available constructions of bulimia nervosa. Seventy-seven adults with varying experience of eating disorders took part in this Q methodological study. Online, they were asked to rank-order 42 statements about bulimia, and then answer a series of questions about the task and their knowledge of bulimia. A by-person factor analysis was then conducted, with factors extracted using the centroid technique and a varimax rotation. Six factors satisfied selection criteria and were subsequently interpreted. Factor A, "bulimia as uncontrolled behavior", positions bulimia as a behavioral rather than psychological issue. Factor B, entitled "bulimia is a distressing mental illness", reflects an understanding of bulimic behaviors as a dysfunctional coping mechanism, which is often found in psychological literature. Other perspectives position bulimia as about "self-medicating with food" (Factor C), "the pathological pursuit of thinness" (Factor D), "being the best at being thin" (Factor E), or as "extreme behavior vs. mentally ill" (Factor F). These constructions have distinct implications for the subjective experience and behavior of those engaged in bulimic behaviors, with some constructions possibly being more useful in terms of help-seeking (Factor B), while others position these individuals in ways that may be distressing, for instance as shallow (Factor D) or to blame (Factor E).

    Studies have documented the impact that hurricanes have on mental health and injury rates before, during, and after the event. Since timely tracking of these disease patterns is crucial to disaster planning, response, and recovery, syndromic surveillance keyword filters were developed by the New York State Department of Health to study the short- and long-term impacts of Hurricane Sandy. Emergency department syndromic surveillance is recognized as a valuable tool for informing public health activities during and immediately following a disaster. Data typically consist of daily visit reports from hospital emergency departments (EDs) of basic patient data and free-text chief complaints. To develop keyword lists, comparisons were made with existing CDC categories and then integrated with lists from the New York City and New Jersey health departments in a collaborative effort. Two comprehensive lists were developed, each containing multiple subcategories and over 100 keywords for both mental health and injury. The data classifiers using these keywords were used to assess impacts of Sandy on mental health and injuries in New York State. The lists will be validated by comparing the ED chief complaint keyword with the final ICD diagnosis code. (Disaster Med Public Health Preparedness. 2017;11:173-178).

    The objective of this study was to review and visualize the medical informatics field over the previous 12 months according to the frequencies of keywords and topics in papers published in the top four journals in the field and in Healthcare Informatics Research (HIR), an official journal of the Korean Society of Medical Informatics. A six-person team conducted an extensive review of the literature on clinical and consumer informatics. The literature was searched using keywords employed in the American Medical Informatics Association year-in-review process and organized into 14 topics used in that process. Data were analyzed using word clouds, social network analysis, and association rules. The literature search yielded 370 references and 1,123 unique keywords. 'Electronic Health Record' (EHR) (78.6%) was the most frequently appearing keyword in the articles published in the five studied journals, followed by 'telemedicine' (2.1%). EHR (37.6%) was also the most frequently studied topic area, followed by clinical informatics (12.0%). However, 'telemedicine' (17.0%) was the most frequently appearing keyword in articles published in HIR, followed by 'telecommunications' (4.5%). Telemedicine (47.1%) was the most frequently studied topic area, followed by EHR (14.7%). The study findings reflect the Korean government's efforts to introduce telemedicine into the Korean healthcare system and reactions to this from the stakeholders associated with telemedicine.

    Non-alcoholic fatty liver (NASH) is widely distributed around the world and is more common in subjects with dyslipidemia, metabolic syndrome obese and DM2 (34-74%). However, the prevalence of cirrhosis by NASH in general population is unknown which is still subject of research. To determine if there are significant differences between metabolic parameters of non-alcoholic fatty liver in controlled versus uncontrolled diabetes type 2 of recent diagnosis. retrospective case-control study, performed in the Hospital Guillermo Almenara Irigoyen, Lima, Peru from November 2014 to February 2015.This study included 231 patients: 147 patients (NASH with DM2 of recent diagnosis and poor control) and 84 patients (NASH with DM2 ofrecent diagnosis and adequate control). Levene test for evaluating homogeneity of variances intra groups and parametric test for independent samples. After applying Levene test of homogeneity and student test, significant metabolic parameters were the triglycerides, HbA1C level, metformin dose and gender. It is important in diabetic patients to diagnose NASH early for a tighter control, not only of glucose but other metabolic parameters mainly triglycerides which strongly supports existing concept of "multiple hits" which considers NASH affects glucose homeostasis, and it could be the starting point of new research to improve interventions for decreasing progression from to cirrhosis in diabetic patients and also to delay progression of diabetes mellitus in patients with non alcoholic steatohepatitis.

    Full Text Available Using images of objects as queries is a new approach to search for information on the Web. Image-based information retrieval goes beyond only matching images, as information in other modalities also can be extracted from data collections using an image search. We have developed a new system that uses images to search for web-based information. This paper has a particular focus on exploring users' experience of general mobile image-based web searches to find what issues and phenomena it contains. This was achieved in a multipart study by creating and letting respondents test prototypes of mobile image-based search systems and collect data using interviews, observations, video observations, and questionnaires. We observed that searching for information based only on visual similarity and without any assistance is sometimes difficult, especially on mobile devices with limited interaction bandwidth. Most of our subjects preferred a search tool that guides the users through the search result based on contextual information, compared to presenting the search result as a plain ranked list.

    Full Text Available The transfer price scope is becoming a very important issue for all companies that comprise from different departments or have a network of branches. These companies are obliged to present the way of price determination for transactions that they have with their branches or other relevant members of their network. The establishment of the multinational companies that develop their activities in various countries is being increased. It has increased the need to supervise their transactions and approval of laws and administrative orders that do not leave space for misuses. The paper is focused in the response to the question if the Comparable Uncontrolled Price Method is the best method to be used in all cases. It is presented through a concrete example that shows how the price of a product determined through the Comparable Uncontrolled Price Method or market price has an impact to the profit of the mother company and other subsidiaries.

    2015-01-01

    Two experiments were conducted to explore the effects of experiencing uncontrollability on the efficiency of attentional control. The experience of uncontrollability was induced either by unsolvable tasks (Experiment 1) or by tasks in which non-contingent feedback was provided (Experiment 2). A version of the Attentional Network Test-Interactions with an additional measure of vigilance (ANTI-V) was used to evaluate the efficiency of the attentional networks (i.e., alerting, orienting, and executive). Results of both experiments revealed a decreased efficiency of executive attention in participants who experienced stable control deprivation but no negative effects in participants who were able to restore their sense of previously deprived control. Additionally, when participants were asked to perform unsolvable tasks and did not receive feedback (Experiment 1), detrimental effects on the orienting network and vigilance were observed. The motivational and cognitive mechanisms underlying the effects of various uncontrollability experiences on conflict resolution and attentional control are discussed. Copyright © 2014 Elsevier B.V.

    Many confirmed genetic loci for obesity are expressed in regions of the brain that regulate energy intake and reward-seeking behavior. Whether these loci contribute to the development of specific eating behaviors has not been investigated. The relationship between a genetic susceptibility to obesity and cognitive restraint, uncontrolled and emotional eating was examined. Eating behavior and body mass index (BMI) were determined by questionnaires for 1471 men and 2381 women from two US cohorts. Genotypes were extracted from genome-wide scans and a genetic-risk score (GRS) derived from 32 obesity-loci was calculated. The GRS was positively associated with emotional and uncontrolled eating (Peating and those of TNNI3K and ZC3H4 were positively associated with uncontrolled eating. The BMI-increasing variant of FTO was positively and those of LRP1B and TFAP2B were inversely associated with cognitive restraint. These associations for single SNPs were independent of BMI but were not significant after multiple-testing correction. An overall genetic susceptibility to obesity may also extend to eating behaviors. The link between specific loci and obesity may be mediated by eating behavior but larger studies are warranted to confirm these results. © 2013 The Obesity Society.

    Full Text Available The present study investigated the effects of three methods of vocabulary presentation, i.e., picture, song, and the keyword method on Iranian EFL learners' vocabulary recognition and production. The participants were 102 Iranian lower-intermediate EFL learners in Zaban Sara English language institute in Kermanshah. To make sure that they had no previous knowledge of the target words, a pretest was administered. Those words about which the participants had prior knowledge were excluded from instruction. After administering the pretest, the participants were divided into three groups. Each group was instructed through a specified method of vocabulary presentation including picture, song, and the keyword method for a whole semester. The participants' receptive vocabulary knowledge was tested through a multiple-choice test and their productive vocabulary knowledge through a fill-in-the blank test. The collected data were analyzed using two separate one-way ANOVA procedures. The results of both tests showed that the group instructed through picture had the best performance, followed closely by the group instructed through the keyword method. The group taught through the song method performed significantly worse than both the picture group and the keyword method group.

    Online personal health record (PHR) is more inclined to shift data storage and search operations to cloud server so as to enjoy the elastic resources and lessen computational burden in cloud storage. As multiple patients' data is always stored in the cloud server simultaneously, it is a challenge to guarantee the confidentiality of PHR data and allow data users to search encrypted data in an efficient and privacy-preserving way. To this end, we design a secure cryptographic primitive called as attribute-based multi-keyword search over encrypted personal health records in multi-owner setting to support both fine-grained access control and multi-keyword search via Ciphertext-Policy Attribute-Based Encryption. Formal security analysis proves our scheme is selectively secure against chosen-keyword attack. As a further contribution, we conduct empirical experiments over real-world dataset to show its feasibility and practicality in a broad range of actual scenarios without incurring additional computational burden.

    The purpose of this study was the evaluation of the effectiveness of supervised rehabilitation in comparison to uncontrolled exercise therapy after surgical reconstruction of rotator cuff interrupted tendons. Twenty two patients with comparable level of disability after the same type of surgery were randomly divided into two equal groups. The first group took part in a supervised therapy and the second one performed simple exercises without supervision. Clinical and neurophysiological examinations were performed prior to rehabilitation and after 20 and 40 days of treatment. The evaluation included the assessment of the pain level with visual analog scale, active range of motion with gonio-meter, activity of muscle's motor units at rest and during maximal effort with electromyography and transmission of motor fibers in brachial plexus with electroneurography (M-wave stimulation studies). In the group of supervised patients the active range of movement changed significantly from 26.4º to 101.5º on average for flexion with adduction while flexion with abduction improved from 21º to 95.5º. Pain sensation changed from 6.4 to 3.2. The mean resting electromyogram amplitude decreased to the greatest degree from 80.9 µV to 36.8 µV in trapezius muscle while maximal effort electromyogram amplitude increased in this muscle from 381.8 µV to 790.9 µV. The mean values of amplitudes in electroneurographical suprascapular nerve examinations increased from 536.4µV to 1691µV. No significant differences at P=0.05 were found in these parameters recorded in the patients performing uncontrolled exercises. The supervised exercise therapy is more effective than uncontrolled one after the rotator cuff surgical reconstruction.

    Human dental pulp stem cells (hDPSCs) hold great promise as a source of adult stem cells for utilization in regenerative medicine. Successful storage and post thaw recovery of DPSCs without loss of function is a key issue for future clinical application. Most of the cryopreservation methods use controlled rate freezing and vapor phase nitrogen to store stem cells. But these methods are both expensive and laborious. In this study, we isolated DPSCs from a patient undergoing impacted mandibular third molar extraction. We adopted eight different methods of cryopreservation at -80 °C for long term storage of the DPSC aliquots. Various parameters like proliferation, cell death, cell cycle, retention of stemness markers and differentiation potential were studied post cryopreservation period of 1 year. We observed successful recovery of stem cells in every method and a significant difference in proliferation potential and cell death between samples stored by different methods. However, post thaw, all cells retained their stemness markers. All DPSCs stored by different methods were able to differentiate into osteoblast like cells, adipocytes and neural cells. Based on these parameters we concluded that uncontrolled freezing at a temperature of -80 °C is as effective as controlled freezing using ethanol vessels and other cryopreservation methods. To the best of our knowledge, our study provides the first proof of concept that long term storage in uncontrolled freezing of cells at -80 °C in 10 % DMSO does not affect the revival capacity of hDPSCs. This implies that DPSCs may be used successfully for tissue engineering and cell based therapeutics even after long term, uncontrolled cryopreservation.

    Incarceration is associated with increased risk of hypertension and cardiovascular disease mortality. We used data from the Veterans Aging Cohort Study (VACS) to explore the impact of incarceration on blood pressure (BP) control. Among hypertensive VACS participants, we measured the association between self-reported recent incarceration or past (not recent) history of incarceration and BP control in the year following the survey. To analyze the association between incarceration and BP control, we used logistic regression models adjusted for sociodemographic characteristics, clinical factors (HIV status and body mass index), and behavioral factors (history of smoking, unhealthy alcohol use, illicit drug use). We explored potential mediators including post-traumatic stress disorder (PTSD), depression, primary care engagement, and adherence to antihypertensive medications. Among the 3515 eligible VACS participants, 2304 participants met the inclusion criteria. Of these, 163 (7 %) reported recent incarceration, and 904 (39 %) reported a past history of incarceration. Participants with recent or past history of incarceration were more likely to have uncontrolled BP than those without a history of incarceration (67 % vs. 56 % vs. 51 %, p incarceration (adjusted odds ratio [AOR] = 1.57 95 % confidence interval [CI]: 1.09-2.26), but not a past history of incarceration (AOR = 1.08 95 % CI: 0.90-1.30), was associated with uncontrolled BP compared with those who were never incarcerated. Among patients with a history of hypertension, recent incarceration is associated with having uncontrolled BP following release. Interventions are needed for recently released individuals to improve hypertension outcomes.

    The continuing shortfall of organs for transplantation has led to interest in Maastricht Category II (uncontrolled) Donation after Circulatory Death (DCD) organ donation. As preparation for a proposed pilot, this study aimed to explore the potential of uncontrolled DCD organ donation from patients presenting in cardiac arrest to the emergency department (ED) who are unsuccessfully resuscitated. We identified all patients who died in our ED following unsuccessful resuscitation after cardiac arrest who were aged between 16 years and 60 years, whose collapse was witnessed, in whom the paramedics arrived within 15 min, whose death in the ED was less than 2 h after their collapse, who were on the organ donation register and who arrived in the ED during the working week (Monday to Friday between 9:00 and 17:00). During a 14-month period from 1 August 2008 to 30 September 2009, 564 patients had a cardiac arrest in the Lothian region. Four patients may have been eligible to participate in an uncontrolled DCD organ donation programme. Identifying potential organ donors in the ED who are unsuccessfully resuscitated from cardiac arrest may contribute to reducing the shortfall of organs for transplantation, although numbers are likely to be small. If such a programme was to be introduced during weekday working hours, there may be around four donors a year. However, even one additional donor per year from hospitals across the UK with an ED and a transplantation service would add considerably to the overall organ donation rate.

    One of the advantages of Internet-based research is the ability to efficiently recruit large, diverse samples of international participants. Currently, there is a dearth of information on the behind-the-scenes process to setting up successful online recruitment tools. The objective of the study was to examine the comparative impact of Spanish- and English-language keywords for a Google AdWords campaign to recruit pregnant women to an Internet intervention and to describe the characteristics of those who enrolled in the trial. Spanish- and English-language Google AdWords campaigns were created to advertise and recruit pregnant women to a Web-based randomized controlled trial for the prevention of postpartum depression, the Mothers and Babies/Mamás y Bebés Internet Project. Search engine users who clicked on the ads in response to keyword queries (eg, pregnancy, depression and pregnancy) were directed to the fully automated study website. Data on the performance of keywords associated with each Google ad reflect Web user queries from February 2009 to June 2012. Demographic information, self-reported depression symptom scores, major depressive episode status, and Internet use data were collected from enrolled participants before randomization in the intervention study. The Google ads received high exposure (12,983,196 impressions) and interest (176,295 clicks) from a global sample of Web users; 6745 pregnant women consented to participate and 2575 completed enrollment in the intervention study. Keywords that were descriptive of pregnancy and distress or pregnancy and health resulted in higher consent and enrollment rates (i.e., high-performing ads). In both languages, broad keywords (eg, pregnancy) had the highest exposure, more consented participants, and greatest cost per consent (up to US $25.77 per consent). The online ads recruited a predominantly Spanish-speaking sample from Latin America of Mestizo racial identity. The English-speaking sample was also diverse

    On 11/07/2012 while investigating the cause of defects in neutron radiography film at HFEF, oil was discovered near the elevator shaft located at the 4M location within the Main Cell. Subsequent investigation identified oil (untracked moderator) in several locations ofthe HFEF Main Cell. Initial analysis determined that oil leaking from a 1M shielding window had leaked past a compensatory containment system resulting in a thin layer of oil found in several locations on the main cell floor. The result of this condition is uncontrolled moderator in moderator controlled zones, which is a violation of Criticality Hazard Control Statements (CHCS) for HFEF.

    Full Text Available Fungal infections affecting the paranasal sinuses are common. They can affect normal as well as immunocompromised individuals. Aspergillosis and mucormycoses are the most common fungal infections involving maxillary sinus. They can manifest in two forms – noninvasive or invasive infection. These infections when properly diagnosed can be treated at the earliest without causing much tissue damage. Here, a noninvasive form of aspergillosis in an uncontrolled diabetic, elderly female patient is presented. This article also explains the etiopathogenesis, clinical and radiological features, as well as the management of aspergillosis.

    Adopting features of the Chronic Care Model may reduce coronary heart disease risk and blood pressure in vulnerable populations. We evaluated a peer and practice team intervention on reduction in 4-year coronary heart disease risk and systolic blood pressure. A single blind, randomized, controlled trial in two adjacent urban university-affiliated primary care practices. Two hundred eighty African-American subjects aged 40 to 75 with uncontrolled hypertension. Three monthly calls from trained peer patients with well-controlled hypertension and, on alternate months, two practice staff visits to review a personalized 4-year heart disease risk calculator and slide shows about heart disease risks. All subjects received usual physician care and brochures about healthy cooking and heart disease. Change in 4-year coronary heart disease risk (primary) and change in systolic blood pressure, both assessed at 6 months. At baseline, the 136 intervention and 144 control subjects' mean 4-year coronary heart disease risk did not differ (intervention=5.8 % and control=6.4 %, P=0.39), and their mean systolic blood pressure was the same (140.5 mmHg, p=0.83). Endpoint data for coronary heart disease were obtained for 69 % of intervention and 82 % of control subjects. After multiple imputation for missing endpoint data, the reduction in risk among all 280 subjects favored the intervention, but was not statistically significant (difference -0.73 %, 95 % confidence interval: -1.54 % to 0.09 %, p=0.08). Among the 247 subjects with a systolic blood pressure endpoint (85 % of intervention and 91 % of control subjects), more intervention than control subjects achieved a >5 mmHg reduction (61 % versus 45 %, respectively, p=0.01). After multiple imputation, the absolute reduction in systolic blood pressure was also greater for the intervention group (difference -6.47 mmHg, 95 % confidence interval: -10.69 to -2.25, P=0.003). One patient died in each study arm. Peer patient and office

    Hypertension is a significant medical and public health issue which puts an enormous burden on health care resources and the community. It is a chronic medical condition in which the systemic arterial blood pressure (BP) is elevated. Serious complications including cardiovascular and cerebrovascular diseases would be preventable if the rise in BP with age could be prevented or diminished. The majority of hypertensive patients require long-term treatment. Oral antihypertensive drugs, lifestyle modification including exercise and dietary modification are milestones for hypertension therapy. However, the control rate of hypertension hasn't reached the expected requirements currently. "Three lows" status quo, just low awareness, low treatment, and low control, are still the major problems confronting modern medicine. Recently, uncontrolled factors of blood pressure are widely concerned, which include insomnia, constipation, mood disorders, exogenous, etc. What's more, the control strategies of hypertension should not only pay close attention to "patient's high blood pressure", but also to "hypertensive patient". Therefore, the treatment of uncontrolled factors of blood pressure plays an important role in hypertensive therapy, which could be further research priorities.

    To study the differences between controlled and uncontrolled hypertensive patients. This was a cross-sectional observational study of the hypertensive population on the lists of three general practitioners in the district of Coimbra in central Portugal in 2013, with a margin of error of 6% and 95% confidence interval in each sample, organized in ascending order of health care user numbers. Data were gathered electronically by the investigators after approval by the Regional Health Authority's ethics committee. A sample of 201 individuals was studied, of whom 104 (51.7%) were male and 86 (42.8%) were aged under 65 (p=0.127 for gender and age-group). Hypertension was controlled in 130 (64.7%). We found significant differences in target organ damage, more frequent in those with controlled hypertension (33.1% vs. 19.7%, p=0.031), in hypertension control, better in those taking at least one anti-hypertensive drug at night (56.9% vs. 29.6%, p<0.001), and in prescription of non-steroidal anti-inflammatory drugs, more frequent in those with uncontrolled hypertension (11.3% vs. 3.8%, p=0.043). Hypertension control is significantly associated with target organ damage, taking at least one anti-hypertensive drug at night and not taking non-steroidal anti-inflammatory drugs simultaneously.

  2. Intention-Aware Autonomous Driving Decision-Making in an Uncontrolled Intersection

    Full Text Available Autonomous vehicles need to perform social accepted behaviors in complex urban scenarios including human-driven vehicles with uncertain intentions. This leads to many difficult decision-making problems, such as deciding a lane change maneuver and generating policies to pass through intersections. In this paper, we propose an intention-aware decision-making algorithm to solve this challenging problem in an uncontrolled intersection scenario. In order to consider uncertain intentions, we first develop a continuous hidden Markov model to predict both the high-level motion intention (e.g., turn right, turn left, and go straight and the low level interaction intentions (e.g., yield status for related vehicles. Then a partially observable Markov decision process (POMDP is built to model the general decision-making framework. Due to the difficulty in solving POMDP, we use proper assumptions and approximations to simplify this problem. A human-like policy generation mechanism is used to generate the possible candidates. Human-driven vehicles’ future motion model is proposed to be applied in state transition process and the intention is updated during each prediction time step. The reward function, which considers the driving safety, traffic laws, time efficiency, and so forth, is designed to calculate the optimal policy. Finally, our method is evaluated in simulation with PreScan software and a driving simulator. The experiments show that our method could lead autonomous vehicle to pass through uncontrolled intersections safely and efficiently.

    Full Text Available Introduction. Epilepsy is one of the most common diseases of the central nervous system. The prevalence of epilepsy throughout the world is 0.5 to 1%, and the same rate is 7.8 per 1000 in Kerman. Almost 20 to 30% of epileptic patients do not respond properly to common medications. The present study investigated patients who did not respond to common and, even in some cases, adjuvant therapies, with two seizures or more per week, regardless of the type of the inflicted epilepsy. Methodology. The participants of the present double-blind study were randomly selected into three 10-member groups of uncontrolled epileptic patients (arginine, glutamic acid, and lysine. The patients used amino acid powder dissolved in water (three times the daily need every day for two weeks before breakfast. The number of seizures was recorded one week prior to commencing amino acid use, as well as the first and the second weeks subsequent to use. Results. A total of 32 patients were studied in three groups. The decline rates of seizures were 53%, 41%, and 13%, and the P value was 0.013, 0.027, and 0.720, respectively. Conclusion. Administration of the charged amino acids, arginine, and glutamic acid can decrease the seizures of patients suffering from uncontrolled epilepsy.

    Full Text Available Objective. The most commonly described technique of modified B-Lynch suture may not be suitable for all the patients presenting with flabby, atonic uterus. Study Design. A retrospective analysis of twelve patients with uncontrolled postpartum haemorrhage, who underwent this procedure from March 2007 to September 2012, was conducted. In this novel technique, sutures are passed in the lower uterine segment and are tightened alternately to control uterine bleeding. Results. Average duration of the procedure was 4 minutes (range 2–7 minutes. Average blood loss was 1625 mL (range 1300–1900 mL. Eleven patients (91.66% were seen to have a successful outcome with only this technique. No patient required hysterectomy and one patient (8.33% required additional bilateral internal iliac artery ligation. All the patients had a minimum follow-up of 2 yrs and none of them reported any infertility problems. Conclusion. This technique is simple, quick, and effective. There was no adverse effect on the fertility potential for the observed 2 years; however, a long-term follow-up is required to comment on its actual rate. This technique cannot replace the standard modified B-Lynch technique for uncontrolled postpartum haemorrhage but can be used for unresponsive, flabby, and atonic uterus.

  6. The medical antigravity suit for management of surgically uncontrollable bleeding associated with abdominal pregnancy.

    Three patients with abdominal pregnancy have been treated at Stanford University Hospital in recent years. Common to each was surgically uncontrolled hemorrhage for which circumferential pneumatic compression (supplied by a medical antigravity suit) was used to stop the bleeding. In each patient, the hemostatic effect of treatment was dramatic. In published accounts of the use of the garment in other severely hemorrhaging patients, the effects have been similarly dramatic and equally successful. These observations lead to a compelling consideration in regard to optimum management of patients with abdominal pregnancy. If our experience is confirmed by others, optimum management in abdominal pregnancy hereafter should regularly and routinely include removal of the placenta at the primary operation. This approach would anticipate use of the medical antigravity suit to provide hemostasis if surgically uncontrollable bleeding is encountered. Theoretically, the complications and long-term morbidity associated with retention of the placenta would be eliminated by this means while the previous disadvantage of placental removal, the potential for exsanguinating hemorrhage, would be circumvented.

    Organ donation after uncontrolled cardiac death raises complex ethical issues. We conducted a survey in a large hospital staff population, including caregivers and administrators, to determine their ethical viewpoints regarding organ donation after uncontrolled cardiac death. Multicenter observational survey using a questionnaire, including information on the practical modalities of the procedure. Respondents were asked to answer 15 detailed ethical questions corresponding to different ethical issues raised in the literature. Ethical concerns was defined when respondents expressed ethical concerns in their answers to at least three of nine specifically selected ethical questions. One thousand one hundred ninety-six questionnaires were received, and 1057 could be analysed. According to our definition, 573 respondents out of 1057 (54%) had ethical concerns with regard to donation after cardiac death and 484 (46 %) had no ethical concerns. Physicians (55%) and particularly junior intensivists (65%) tended to have more ethical issues than nurses (52%) and hospital managers (37%). Junior intensivists had more ethical issues than senior intensivists (59%), emergency room physicians (46%) and transplant specialists (43%). Only 46% of hospital-based caregivers and managers appear to accept easily the legitimacy of organ donation after cardiac death. A significant number of respondents especially intensivists, expressed concerns over the dilemma between the interests of the individual and those of society. These results underline the need to better inform both healthcare professionals and the general population to help to the development of such procedure. © 2013 The Acta Anaesthesiologica Scandinavica Foundation.

    Pulmonary mucormycosis is a rare opportunistic infection with high mortality that is caused by species of Mucorales. The most common species involved are Rhizopus, Mucor, Lichtheimia, and Rhizomucor. A 56 year-old woman presented with a clinical history of diabetes mellitus type 2 and chronic renal disease. She underwent a cadaveric kidney transplantation two years before her admission, for which immunomodulating therapy with thymoglobulin, tacrolimus, mofetil-microphenolate and prednisone was established. The patient suffered a pneumonic process with cough, expectoration, and dyspnoea. The computed tomography scan showed a cavitation in the right upper lobe. With all these findings an invasive broncopulmonary aspergillosis was suspected and the patient began an antifungal treatment with voriconazole without improvement. Rhizomucor pusillus was isolated from a clinical specimen obtained by fine needle aspiration, and its identification was confirmed by PCR. After this finding amphotericin B was administered, but the patient had an uncontrolled haemoptysis and died. Pulmonary mucormycosis is a rare infection, usually fatal in kidney transplant recipients with anti-rejection therapy. Mucorales species usually produce thrombotic phenomena, associated with necrosis and parenchymal destruction that caused a fatal uncontrolled haemoptysis in our patient. Early diagnosis is important in order to perform any surgical treatment and to administer amphotericin B. Copyright © 2017 Asociación Española de Micología. Publicado por Elsevier España, S.L.U.

    Full Text Available The dermal filler Princess VOLUME is a highly cross-linked, viscoelastic hyaluronic acid injectable gel implant used for aesthetic treatment. To evaluate the efficacy and safety of Princess VOLUME in the treatment of nasolabial folds, an open-label uncontrolled, multicenter study was conducted. Forty-eight subjects were recruited who had moderate to deep wrinkles, according to the Modified Fitzpatrick Wrinkle Scale (MFWS. Subjects received Princess VOLUME in both nasolabial folds at Day 0. Nasolabial fold severity was evaluated at 30, 90, 180, and 270 days after treatment, using the MFWS and the Global Aesthetic Improvement Scale (GAIS. Adverse events and treatment site reactions were recorded. Among the 48 subjects, 93.8% were female with a median age of 52 years. There were significant improvements (P<0.0001 in the MFWS scores at 30, 180, and 270 days after treatment compared with those at baseline, with a mean decrease of 1.484 (±0.408, 1.309 (±0.373, and 1.223 (±0.401, respectively; hence the primary endpoint was achieved and clinical efficacy demonstrated.

    Patients with uncontrolled type 1 diabetes mellitus may be candidates for pancreatic islet cell transplantation. This report synthesizes qualitative research on how patients with uncontrolled type 1 diabetes perceive their quality of life. The objective of this analysis was to examine the perceptions of patients with uncontrolled type 1 diabetes on how it affects their lived experience and quality of life. This report synthesizes 31 primary qualitative studies to examine quality of life from the perspectives of adult patients with type 1 diabetes mellitus and their families or partners. We performed a qualitative meta-synthesis to integrate findings across primary research studies. Long- and short-term negative consequences of uncontrolled type 1 diabetes affect all aspects of patients' lives: physical, emotional, practical, and social. The effect on each domain is far-reaching, and effects interact across domains. Uncontrolled blood sugar levels lead to substantial psychological distress, negative moods, cognitive difficulties, irritable or aggressive behaviour, and closely associated problems with relationships, self-image, and confidence. Emotional distress is pervasive and under-addressed by health care providers. Patients live in fear of complications from diabetes over the long term. In the shorter term, they are anxious about the personal, social, and professional consequences of hypoglycemic episodes (e.g., injury, humiliation), and may curtail normal activities such as driving or socializing because they are worried about having an episode. The quality of life for patients' family members is also negatively impacted by uncontrolled type 1 diabetes. Uncontrolled type 1 diabetes has significant negative impacts on the quality of life of both people with the disease and their families.

    Rationale: Abdominal adiposity may be an important risk factor for uncontrolled asthma in adults, controlling for general obesity. Whether the relationship, if present, is explained by other factors (e.g., asthma onset age, sex, and/or coexisting conditions) is unclear. Objectives: To examine whether clinically applicable anthropometric measures of abdominal adiposity—waist circumference and waist-to-height ratio (WHtR)—are related to poorer asthma control in adults with uncontrolled asthma controlling for body mass index (BMI), and whether the relationship (if present) is explained by gastroesophageal reflux disorder (GERD), sleep quality, or obstructive sleep apnea (OSA) or differs by age of asthma onset or sex. Methods: Patients aged 18 to 70 years with uncontrolled asthma (n = 90) participated in a 6-month randomized clinical trial. Measurements and Main Results: Baseline measures included sociodemographics, standardized anthropometrics, Asthma Control Test (ACT), GERD Symptom Assessment Scale, Pittsburgh Sleep Quality Index, and Berlin Questionnaire for Sleep Apnea. Participants (mean [SD] age, 52 [12] yr) were racially and ethnically diverse, 67% women, and 69% overweight or obese, and 71% reported their age of asthma onset was 12 years or older. Participants had uncontrolled asthma (mean [SD] ACT score, 14.9 [3.7]) and low GERD symptoms score (0.6 [0.4]); 67% reported poor sleep quality, and 42% had a high OSA risk. General linear regression results showed that worse ACT scores were significantly associated with every SD increase in waist circumference (β= −1.03; 95% confidence interval [CI], −1.96 to −0.16; P = 0.02) and waist-to-height ratio (β= −1.16; 95% CI, −2.00 to −0.33; P = 0.008), controlling for sociodemographics. Waist-to-height ratio remained correlated with ACT (β= −2.30; 95% CI, −4.16 to −0.45; P = 0.02) after further adjusting for BMI. The BMI-controlled relationship between WHtR and ACT did not differ by age of asthma

    The study tested the effects of positive mood enhancement on chocolate chip cookie consumption in the context of emotional and uncontrolled eating styles. The relationship between emotional eating style and chocolate chip cookie intake was assumed to be mediated by uncontrolled eating style. Further, it was hypothesized that the effectiveness of the positive mood enhancement may be more salient among those who have effective control of their eating. In this experimental study, respondents (N=106, 70% women, aged 16-45 years old) were assigned by means of cluster randomization to the control or positive mood enhancement condition (a comedy movie clip). Compared to the control condition, positive mood enhancement resulted in consuming on average 53.86 kcal less. Relationships between emotional eating style and cookie intake were mediated by uncontrolled eating. Moderated mediation analysis indicated that the effect of a mediator (uncontrolled eating) on cookie intake was moderated by the group assignment. Positive mood enhancement resulted in eating on average 3.3 cookies less among individuals with a more controlled eating style. By contrast, among those who presented uncontrolled eating, positive mood enhancement led to consuming an average of 1.7 cookies more. 2009 Elsevier Ltd. All rights reserved.

    Full Text Available OBJECTIVES: Nucleoside reverse transcriptase inhibitors (NRTIs used in HIV antiretroviral therapy can inhibit human telomerase reverse transcriptase. We therefore investigated whether in utero or childhood exposure to NRTIs affects leukocyte telomere length (LTL, a marker of cellular aging. METHODS: In this cross-sectional CARMA cohort study, we investigated factors associated with LTL in HIV-1-infected (HIV(+ children (n = 94, HIV-1-exposed uninfected (HEU children who were exposed to antiretroviral therapy (ART perinatally (n = 177, and HIV-unexposed uninfected (HIV(- control children (n = 104 aged 0-19 years. Univariate followed by multivariate linear regression models were used to examine relationships of explanatory variables with LTL for: a all subjects, b HIV(+/HEU children only, and c HIV(+ children only. RESULTS: After adjusting for age and gender, there was no difference in LTL between the 3 groups, when considering children of all ages together. In multivariate models, older age and male gender were associated with shorter LTL. For the HIV(+ group alone, having a detectable HIV viral load was also strongly associated with shorter LTL (p = 0.007. CONCLUSIONS: In this large study, group rates of LTL attrition were similar for HIV(+, HEU and HIV(- children. No associations between children's LTL and their perinatal ART exposure or HIV status were seen in linear regression models. However, the association between having a detectable HIV viral load and shorter LTL suggests that uncontrolled HIV viremia rather than duration of ART exposure may be associated with acceleration of blood telomere attrition.

    As we progress into the 21st century, the world faces challenges of truly global nature bearing implications on the whole world in one way or another. The global economic engine has shifted from the western world (Developed Economies) to the eastern world (Developing Economies) which has brought about tremendous change in the climate related variables in this part of the world. As uncontrolled carbon emissions grow in the developing economies, the phenomenon of global warming and climate shifts become more and more prevalent. While this economic activity provides income for millions of households, it is contributing generously to the rapid degradation of the environment. Developing economies as it has been seen do not employ or abide by stringent regulations regarding emissions which result in uncontrolled emissions. In this particular scenario, it is a tedious task to convince governments in the developing economies to implement regulations regarding emissions because businesses in these economies deem such regulations to be economically unviable. The other side of the problem is that these uncontrolled emission are causing evident climate shifts which has had adverse impacts on the agricultural societies where shifting climates are leading to reduced agricultural output and productivity. Consequently the lives of millions associated directly or indirectly with agriculture are affected and on a more global level, the agricultural produce is decreasing which increases the chances of famine in parts of the world. The situation could have devastating impacts on the global economy and environmental standards and therefore needs to be addressed on emergency basis. The first step towards betterment could be the introduction of the carbon trading economy in the developing economies which would incentivize emission reduction and become more attractive and in the process sustaining minimum possible damage to the environment. Though carbon trading is a formidable first step

    Pheochromocytoma is a rare tumor in adults, with an estimated annual incidence of 0.8 per 100,000 persons. Cardiomyopathy is an uncommon presentation of such a rare disease. Serious cardiovascular complications of these tumors are related to potent effects of secreted catecholamines. The mechanism of pheochromocytoma-related cardiomyopathy is not well understood but it is likely due to the effect of excess catecholamines and their oxidation products which have been found to have a direct toxic effect on the myocardium. We describe below a case of a 70-year old female with uncontrolled hypertension and new onset acute systolic heart failure, who on further evaluation was noted to have pheochromocytoma-related cardiomyopathy. Pheochromocytoma should be strongly considered in the differential diagnosis of non-ischemic cardiomyopathy for a patient with elevated blood pressures relative to severity of cardiac dysfunction.

    A number of plants of ancestral tradition exhibit properties deserving therapeutic applications. However, their use in conditions which do not guarantee sufficient safety may lead to incidences and sometimes serious accidents. In the US the weakness of the present provisions of the federal regulation do not allow a satisfactory and preliminary control. Moreover, these plants are mostly prescribed by non-medicals and outside the authority of pharmacists. This situation would be highly prejudicial if it would be implemented in Europe. France has a well conceived and satisfactory system, but which is unable to benefit from new accessions, namely exotic plants. To ignore them would lead to strengthening the already existing and parallel organizations. The authors suggest that the health authorities should create a complementary system open to new medicinal plants, avoiding uncontrolled sales. They suggest also that before any acceptance a realistic probationary period would be applied in order to evaluate the quality but overall the eventual toxicity of these plants.

    To investigate the effectiveness of workplace exercise for employee health by means of health-related physical activity components. A randomized uncontrolled study with 20 workers was carried out during three months to evaluate a workplace exercise program. The selected outcomes were flexibility, body mass, fat percentage, lean mass, blood pressure, and heart rate. For statistical analysis, the paired t test and the intent-to-treat analysis were used. There was a significant increase in weight, fat percentage, blood pressure, and heart rate. However the clinical significance was 10% in the size of the effect. The changes verified in the outcomes analyzed were not significant; the variables are within normality ranges proposed by academic organizations.

    Full Text Available Warfarin is an oral anticoagulant, which is commonly used in the treatment and prophylaxis of thromboembolic conditions. Bleeding is the primary adverse effect associated with warfarin. The majority of warfarin-related bleedings are spontaneous minor hemorrhages occurring in the subcutaneous or intramuscular tissues and can be treated by decreasing the dose of oral anticoagulants. However, although rare, it is possible to encounter spontaneous major bleedings with increased risk of mortality. Conservative approach is the preferred initial therapy for hemodynamically stable patients with major intra-abdominal hemorrhages that we define as the intermediate group patients. Nevertheless, surgery is required for hemodynamically unstable patients with acute abdominal pain in cases of ongoing active hemorrhage, generalized peritonitis, obstruction, acute abdomen, intestinal ischemia, and perforation. In this article, we present a rare case of acute abdomen and spontaneous intra-abdominal hemorrhage resulting from uncontrolled use of warfarin and a new classification requirement.

    In the study area, uncontrolled landfill leachate is a serious cause of groundwater contamination that occurs extensively and rapidly following the rainy season. For this reason, the use of traditional hydrogeological monitoring methods using drilled wells is expensive and limited. Electrical resistivity imaging (ERI) is suitable for monitoring groundwater contamination because this method helps quickly investigate a large site without the need for well drilling. The resistivity of the landfill leachate is lower than that of clean groundwater; based on this fact, we evaluated the diffusion of landfill leachate before and after the rainy season using 3-D ERI characterization. In addition, ERI results were compared with piezometric and hydrochemical data obtained from observation wells for the purpose of cross-validation. The groundwater monitoring results agreed with the 2-D and 3-D interpretation of ERI results. The electrical resistivity values of contaminated zones were lower than those of clean zones due to an abundance of ions or molecules in the groundwater. The resistivity boundary between contaminated and clean zones observed in the inverted 2-D and 3-D ERI sections was considered to be approximately 100 Ω-m. The low-resistivity anomaly of the contamination zones increased in extent after rainfall. The expansion was likely accelerated by groundwater movement and diffusion of the landfill leachate. Images of the change in electrical resistivity were helpful for characterization of the behavior. The two-directional behaviors of NE-SW and N-S trends were confirmed by the 3-D ratio images. It is therefore, considered that the ERI technique is excellent for imaging contaminated zones as well as monitoring the behaviors of landfill leachate in uncontrolled landfills.

    Full Text Available Uncontrolled hemorrhage, resulting from traumatic injuries, continues to be the leading cause of death in civilian and military environments. Hemorrhagic deaths usually occur within the first 6 hours of admission to hospital; therefore, early prehospital identification of patients who are at risk for developing shock may improve survival. The aims of the current study were: 1. To establish and characterize a unique model of uncontrolled internal hemorrhage induced by massive renal injury (MRI, of different degrees (20-35% unilateral nephrectomy in rats, 2. To identify early biomarkers those best predict the outcome of severe internal hemorrhage. For this purpose, male Sprague Dawley rats were anesthetized and cannulas were inserted into the trachea and carotid artery. After abdominal laparotomy, the lower pole of the kidney was excised. During 120 minutes, hematocrit, pO2, pCO2, base excess, potassium, lactate and glucose were measured from blood samples, and mean arterial pressure (MAP was measured through arterial tracing. After 120 minutes, blood loss was determined. Statistical prediction models of mortality and amount of blood loss were performed. In this model, the lowest blood loss and mortality rate were observed in the group with 20% nephrectomy. Escalation of the extent of nephrectomy to 25% and 30% significantly increased blood loss and mortality rate. Two phases of hemodynamic and biochemical response to MRI were noticed: the primary phase, occurring during the first 15 minutes after injury, and the secondary phase, beginning 30 minutes after the induction of bleeding. A Significant correlation between early blood loss and mean arterial pressure (MAP decrements and survival were noted. Our data also indicate that prediction of outcome was attainable in the very early stages of blood loss, over the first 15 minutes after the injury, and that blood loss and MAP were the strongest predictors of mortality.

    Uncontrolled hypothyroidism has been associated with an increased risk of adverse pregnancy outcomes. We aimed to assess the effectiveness of increasing levothyroxine (LT4) dose on reducing the risk of adverse outcomes for pregnant women with TSH level greater than the recommended 1st trimester limit. We reviewed the electronic medical records of pregnant women evaluated from January 2011 to December 2013, who had history of LT4-treated hypothyroidism and were found to have TSH > 2·5 mIU/l in 1st trimester. Women were divided into two groups: group A - LT4 dose was increased within two weeks from the TSH test, group B - LT4 dose remained stable. We compared the frequency of pregnancy loss (primary outcome) and other prespecified pregnancy-related adverse outcomes between groups. There were 85 women in group A (median TSH: 5·0, interquartile range 3·8-6·8 mIU/l) and 11 women in group B (median TSH: 4·5, interquartile range 3·2-4·9 mIU/l). The groups were not different in baseline clinical and socioeconomic characteristics. The mean interval between TSH test and LT4 dose increase was 4·5 (SD 4·6) days. Pregnancy loss was significantly lower in group A (2/85, 2·4%) vs group B (4/11, 36·4%) (P = 0·001). Other pregnancy-related adverse outcomes were similar between groups. Increasing LT4 dose for women with uncontrolled hypothyroidism in the 1st trimester of pregnancy was associated with a decreased risk of pregnancy loss. Given the limitations of our study, this association awaits further confirmation from larger studies. © 2016 John Wiley & Sons Ltd.

    Hemorrhage is the leading cause of potentially survivable trauma mortality, necessitating the development of improved therapeutic interventions. The objective of this study was to develop and characterize a reproducible clinically translatable nonhuman primate model of uncontrolled severe hemorrhage. Such a model is required to facilitate the development and meaningful evaluation of human-derived therapeutics. In Rhesus macaques, a laparoscopic left-lobe hepatectomy of 25% (n = 2), 50% (n = 4), or 60% (n = 6) was performed at T = 0 min, with no attempt at hemorrhage control until T = 120 min. A constant-rate infusion of normal saline was administered between T = 15 and 120 min to a total volume of 20 mL/kg. At T = 120 min, a laparotomy was performed to gain surgical hemostasis and quantify blood loss. Physiological parameters were recorded, and blood samples were collected at defined intervals until termination of the study at T = 480 min. Statistical analyses used Student t tests, with P < 0.05 considered statistically significant. Results are reported as mean ± SEM. The calculated percent blood loss for the 25% hepatectomy group was negligible (2.3% ± 0.2%), whereas the 50% and 60% hepatectomy groups exhibited 26.6% ± 7.1% and 24.9% ± 3.8% blood loss, respectively. At T = 5 min, blood pressure for the 25%, 50%, and 60% hepatectomy groups was reduced by 13.8%, 60.8%, and 63.2% from the respective baseline values (P < 0.05). In the 60% hepatectomy group, alterations in thromboelastometry parameters and systemic inflammatory markers were observed. The development of a translatable nonhuman primate model of uncontrolled hemorrhage is an ongoing process. This study demonstrates that 60% hepatectomy offers a significant reproducible injury applicable for the evaluation of human-derived therapeutics.

    Full Text Available Early language learning for children is increasingly common, and the majority of parents and the public do not see it as superfluous or overburdening children. Moreover, teaching a foreign language to very young children has been an increasingly dominant trend in most globalized societies. While there is abundant literature that supports teaching a foreign language at an early age through language immersion programs, little is known about the efficiency of strategies used to explicitly teach new vocabulary words in a foreign language to young learners. This empirical investigation aimed to assess and compare the efficiency of two mnemonics that have been traditionally used to explicitly teach new foreign language words: the Keyword Method (KWM and the Total Physical Response (TPR. Results indicate that the KWM is more effective than TPR in teaching new vocabulary words in a foreign language to early elementary school children.

    Full Text Available First-line therapy of hypertension includes diuretics, known to exert a multiplicative increase on the risk of gout. Detailed insight into the underlying prevalence of hyperuricemia and gout in persons with uncontrolled blood pressure (BP and common comorbidities is informative to practitioners initiating antihypertensive agents. We quantify the prevalence of hyperuricemia and gout in persons with uncontrolled BP and additional cardiovascular disease (CVD risk factors.We performed a cross-sectional study of non-institutionalized US adults, 18 years and older, using the National Health and Nutrition Examination Surveys in 1988-1994 and 1999-2010. Hyperuricemia was defined as serum uric acid >6.0 mg/dL in women; >7.0 mg/dL in men. Gout was ascertained by self-report of physician-diagnosed gout. Uncontrolled BP was based on measured systolic BP≥140 mmHg and diastolic BP≥90 mmHg. Additional CVD risk factors included obesity, reduced glomerular filtration rate, and dyslipidemia. The prevalence of hyperuricemia was 6-8% among healthy US adults, 10-15% among adults with uncontrolled BP, 22-25% with uncontrolled BP and one additional CVD risk factor, and 34-37% with uncontrolled BP and two additional CVD risk factors. Similarly, the prevalence of gout was successively greater, at 1-2%, 4-5%, 6-8%, and 8-12%, respectively, across these same health status categories. In 2007-2010, those with uncontrolled BP and 2 additional CVD risk factors compared to those without CVD risk factors had prevalence ratios of 4.5 (95% CI 3.5-5.6 and 4.5 (95% CI: 3.1-6.3 for hyperuricemia and gout respectively (P<0.01.Health care providers should be cognizant of the incrementally higher prevalence of hyperuricemia and gout among patients with uncontrolled BP and additional CVD risk factors. With one in three people affected by hyperuricemia among those with several CVD risk factors, physicians should consider their anti-hypertensive regimens carefully and potentially

    Full Text Available Francesco Di Pierro,1 Daniele Di Pasquale,2 Maurizio Di Cicco2 1Velleja Research, Milan, Italy; 2ORL Department, Ospedale Maggiore Policlinico Ca’ Grande IRCCS, Milan, Italy Abstract: Secretory otitis media (SOM remains a common disease among children. Although its cause is not yet perfectly established, the pathology, often a sequel of acute otitis media (AOM, is mainly characterized by persistent fluid in the middle ear cavity. Twenty-two children with a diagnosis of SOM were treated daily for 90 days with an oral formulation containing the oral probiotic Streptococcus salivarius K12 (Bactoblis®. After treatment, the children were evaluated for AOM episodes and subjected to tone audiometry, tympanometry, endonasal endoscopy, otoscopy, and tonsillar examination. Subject compliance and probiotic tolerability and side effects have also been evaluated. Our results indicate a good safety profile, a substantial reduction of AOM episodes, and a positive outcome from the treatment for all of the clinical outcomes tested. We conclude that strain K12 may have a role in reducing the occurrence and/or severity of SOM in children. From our perspective, this study constitutes a starting point toward the organization of a more extensive placebo-controlled study aimed at critically appraising our preliminary observations.

    Asai, Kikuo; Kondo, Kimio; Kobayashi, Hideaki; Saito, Fumihiko

    We developed a prototype system to support telecommunication by using keywords selected by the speaker in a videoconference. In the traditional presentation style, a speaker talks and uses audiovisual materials, and the audience at remote sites looks at these materials. Unfortunately, the audience often loses concentration and attention during the talk. To overcome this problem, we investigate a keyword presentation style, in which the speaker holds keyword cards that enable the audience to see additional information. Although keyword captions were originally intended for use in video materials for learning foreign languages, they can also be used to improve the quality of distance lectures in videoconferences. Our prototype system recognizes printed keywords in a video image at a server, and transfers the data to clients as multimedia functions such as language translation, three-dimensional (3D) model visualization, and audio reproduction. The additional information is collocated to the keyword cards in the display window, thus forming a spatial relationship between them. We conducted an experiment to investigate the properties of the keyword presentation style for an audience. The results suggest the potential of the keyword presentation style for improving the audience's concentration and attention in distance lectures by providing an environment that facilitates eye contact during videoconferencing.

    Self-adjustment of insulin dose is commonly practiced in Western patients with type 2 diabetes but is usually not performed in Asian patients. This multinational, 24-week, randomized study compared patient-led with physician-led titration of once-daily insulin glargine in Asian patients with uncontrolled type 2 diabetes who were on 2 oral glucose-lowering agents. Patient-led (n = 275) or physician-led (n = 277) subjects followed the same dose-titration algorithm guided by self-monitored fasting blood glucose (FBG; target, 110 mg/dL [6.1 mmol/L]). The primary endpoint was change in mean glycated hemoglobin (HbA1c) at week 24 in the patient-led versus physician-led titration groups. Patient-led titration resulted in a significantly higher drop in HbA1c value at 24 weeks when compared with physician-led titration (-1.40% vs. -1.25%; mean difference, -0.15; 95% confidence interval, -0.29 to 0.00; P = .043). Mean decrease in FBG was greatest in the patient-led group (-2.85 mmol/L vs. -2.48 mmol/L; P = .001). The improvements in HbA1c and FBG were consistent across countries, with similar improvements in treatment satisfaction in both groups. Mean daily insulin dose was higher in the patient-led group (28.9 units vs. 22.2 units; Ptitration achieved near-target blood glucose levels in Asian patients with uncontrolled type 2 diabetes who were on 2 oral glucose-lowering drugs, demonstrating that Asian patients can self-uptitrate insulin dose effectively when guided.

  11. Glucose-reducing effect of the ORMD-0801 oral insulin preparation in patients with uncontrolled type 1 diabetes: a pilot study.

    Roy Eldor

    Full Text Available The unpredictable behavior of uncontrolled type 1 diabetes often involves frequent swings in blood glucose levels that impact maintenance of a daily routine. An intensified insulin regimen is often unsuccessful, while other therapeutic options, such as amylin analog injections, use of continuous glucose sensors, and islet or pancreas transplantation are of limited clinical use. In efforts to provide patients with a more compliable treatment method, Oramed Pharmaceuticals tested the capacity of its oral insulin capsule (ORMD-0801, 8 mg insulin in addressing this resistant clinical state. Eight Type I diabetes patients with uncontrolled diabetes (HbA1c: 7.5-10% were monitored throughout the 15-day study period by means of a blind continuous glucose monitoring device. Baseline patient blood glucose behavior was monitored and recorded over a five-day pretreatment screening period. During the ensuing ten-day treatment phase, patients were asked to conduct themselves as usual and to self-administer an oral insulin capsule three times daily, just prior to meal intake. CGM data sufficient for pharmacodynamics analyses were obtained from 6 of the 8 subjects. Treatment with ORMD-0801 was associated with a significant 24.4% reduction in the frequencies of glucose readings >200 mg/dL (60.1 ± 7.9% pretreatment vs. 45.4 ± 4.9% during ORMD-0801 treatment; p = 0.023 and a significant mean 16.6% decrease in glucose area under the curve (AUC (66055 ± 5547 mg/dL/24 hours vs. 55060 ± 3068 mg/dL/24 hours, p = 0.023, with a greater decrease during the early evening hours. In conclusion, ORMD-0801 oral insulin capsules in conjunction with subcutaneous insulin injections, well tolerated and effectively reduced glycemia throughout the day.Clinicaltrials.gov NCT00867594.

    Full Text Available As the number of hypertext documents are increasing continuously day by day on world wide web. Therefore clustering methods will be required to bind documents into the clusters repositories according to the similarity lying between the documents. Various clustering methods exist such as Hierarchical Based K-means Fuzzy Logic Based Centroid Based etc. These keyword based clustering methods takes much more amount of time for creating containers and putting documents in their respective containers. These traditional methods use File Handling techniques of different programming languages for creating repositories and transferring web documents into these containers. In contrast openstack4j SDK is a new technique for creating containers and shifting web documents into these containers according to the similarity in much more less amount of time as compared to the traditional methods. Another benefit of this technique is that this SDK understands and reads all types of files such as jpg html pdf doc etc. This paper compares the time required for clustering of documents by using openstack4j and by traditional methods and suggests various search engines to adopt this technique for clustering so that they give result to the user querries in less amount of time.

    Preserving the privacy of electronic medical records (EMRs) is extremely important especially when medical systems adopt cloud services to store patients' electronic medical records. Considering both the privacy and the utilization of EMRs, some medical systems apply searchable encryption to encrypt EMRs and enable authorized users to search over these encrypted records. Since individuals would like to share their EMRs with multiple persons, how to design an efficient searchable encryption for sharable EMRs is still a very challenge work. In this paper, we propose a cost-efficient secure channel free searchable encryption (SCF-PEKS) scheme for sharable EMRs. Comparing with existing SCF-PEKS solutions, our scheme reduces the storage overhead and achieves better computation performance. Moreover, our scheme can guard against keyword guessing attack, which is neglected by most of the existing schemes. Finally, we implement both our scheme and a latest medical-based scheme to evaluate the performance. The evaluation results show that our scheme performs much better performance than the latest one for sharable EMRs.

    To evaluate the safety, effect on visual function, and fluorescein angiographic appearance of subfoveal choroidal neovascularization (CNV) through 2 years after photodynamic therapy with verteporfin (Visudyne; Novartis AG, Basel, Switzerland) in patients with ocular histoplasmosis syndrome (OHS). Open-label, 3-center, uncontrolled clinical study. Ocular histoplasmosis syndrome patients with subfoveal CNV (N = 26) with a greatest linear dimension no larger than 5400 microm with classic or occult CNV extending under the geometric center of the fovea, and best-corrected visual acuity letter score of approximately 20/40 to 20/200. The methods were similar to those described in the 1-year results with follow-up examinations every 3 months continuing through the second year. During the second year, additional therapy was recommended if fluorescein angiography showed leakage at a scheduled visit. Visual function measurements included the changes from baseline in visual acuity and contrast sensitivity scores. Lesion size and leakage from classic and occult CNV were assessed at month 12 and month 24. Safety assessments also were made. A 24-month examination was completed in 22 of the 26 enrolled participants (85%). At the 24-month examination, median improvement from baseline in visual acuity of the 22 patients evaluated was 6 letters; median contrast sensitivity improved by 3.5 letters. At the 24-month examination, 10 patients (45%) gained 7 or more letters of visual acuity from baseline, whereas 4 patients (18%) lost 8 or more letters, including 2 patients (9%) who lost at least 15 letters. There was absence of fluorescein angiographic leakage from classic CNV in 17 of the 20 evaluable lesions (85%), and leakage from occult CNV was absent in all eyes. No serious ocular adverse events were reported, and no serious systemic event was considered to be associated with treatment. Median visual acuity improved and fluorescein angiographic leakage decreased after verteporfin

    This multi-faceted study evaluated several aspects of uncontrolled air flows in commercial buildings in both Northern and Southern climates. Field data were collected from 25 small commercial buildings in New York State to understand baseline conditions for Northern buildings. Laboratory wall assembly testing was completed at Syracuse University to understand the impact of typical air leakage pathways on heat and moisture transport within wall assemblies for both Northern and Southern building applications. The experimental data from the laboratory tests were used to verify detailed heat and moisture (HAM) simulation models that could be used to evaluate a wider array of building applications and situations. Whole building testing at FSEC's Building Science Laboratory (BSL) systematically evaluated the energy and IAQ impacts of duct leakage with various attic and ceiling configurations. This systematic test carefully controlled all aspects of building performance to quantify the impact of duct leakage and unbalanced flow. The newest features of the EnergyPlus building simulation tool were used to model the combined impacts of duct leakage, ceiling leakage, unbalanced flows, and air conditioner performance. The experimental data provided the basis to validate the simulation model so it could be used to study the impact of duct leakage over a wide range of climates and applications. The overall objective of this project was to transfer work and knowledge that has been done on uncontrolled air flow in non-residential buildings in Florida to a national basis. This objective was implemented by means of four tasks: (1) Field testing and monitoring of uncontrolled air flow in a sample of New York buildings; (2) Detailed wall assembly laboratory measurements and modeling; (3) Whole building experiments and simulation of uncontrolled air flows; and (4) Develop and implement training on uncontrolled air flows for Practitioners in New York State.

    Full Text Available Landfill leachates are potential threats for environmental degradation. This study was conducted to determine the leachate quality, to identify the dominant pollutants and to evaluate the leachate pollution potential of an active and closed dumping ground of an uncontrolled municipal solid waste landfill site in Kolkata, India using leachate pollution index. The results of the physico-chemical and biological analyses of leachate indicated that landfill site was in its methanogenic phase. Among the analysed leachate pollutants, TDS, BOD5, COD, TKN, NH3-N, Cl¯, TCB, Pb, and Hg surpassed the leachate discharge standards for inland surface water as specified by the municipal solid waste (Management and Handling Rules, 2013 for both the dumping grounds. Moreover the concentrations of total Cr and Zn also exceeded the leachate disposal standards for the active dumping ground. The leachate pollution potentialities of both the active and closed dumping grounds were comparable as the overall LPI obtained 34.02 and 31.80 respectively. The overall LPI, LPI organic (LPIor, LPI inorganic (LPIin and LPI heavy metals (LPIhm of both the dumping grounds largely exceeded the LPI and sub-LPI values for treated leachate before disposal to the inland surface water. In terms of the individual pollution rating, total coliform bacteria, TKN, NH3-N and Hg were identified as the dominant pollutants and major contributing factors for the leachate pollution potential.

    Multi-infusion systems are used frequently at intensive care units to administer several liquid therapeutic agents to patients simultaneously. By passively combining the separate infusion lines in one central line, the number of punctures needed to access the patient's body, is reduced. So far, the mutual influence between the different infusion lines is unknown. Although the flow properties of single infusion systems have been investigated extensively, only a few research groups have investigated the flow properties of multi-infusion systems. We showed in a previous study that applying multi-infusion can lead to fluctuations in syringe pump infusions, resulting in uncontrolled and inaccurate drug administration. This study presents a performance analysis of multi-infusion systems as used in the Neonatology Intensive Care Unit. The dynamics between multiple infusion lines in multi-infusion systems were investigated by simulation experiments of clinical conditions. A newly developed real-time spectral-photometric method was used for the quantitative determination of concentration and outflow volume using a deconvolution method of absorption spectra of mixed fluids. The effects for common clinical interventions were studied in detail. Results showed mutual influence between the different infusion lines following these interventions. This mutual influence led to significant volume fluctuations up to 50%. These deviations could result in clinically dangerous situations. A complete analysis of the multiinfusion system characteristics is recommended in further research to estimate both the presence and severity of potential risks in clinical use.

  3. Studies of Limits on Uncontrolled Heavy Ion Beam Losses for Allowing Hands-On Maintenance

    Dose rates from accelerator components activated by 1 W/m beam losses are obtained semiempirically for a 1 GeV proton beam and by use of Monte Carlo transport codes for the proton beam and for 777 MeV/u 3He, 500 MeV/u 48Ca, 86Kr, 136Xe, and 400 MeV/u 238U ions. The dose rate obtained by the semi-empirical method, 0.99 mSv/h (99 mrem/h) at 30 cm, 4 h after 100 d irradiation by a 1-GeV proton beam, is consistent with studies at several accelerator facilities and with adopted hands-on maintenance dose rate limits. Monte Carlo simulations verify this result for protons and extend studies to heavy ion beam losses in drift-tube linac and superconducting linac accelerating structures. The studies indicate that the 1 W/m limit imposed on uncontrolled beam losses for high-energy proton beams might be relaxed for heavy ion beams. These studies further suggest that using the ratio of neutrons produced by a heavy ion beam to neutrons produced by a proton beam along with the dose rate from the proton beam (for thin-target scenarios) should allow an estimate of the dose rates expected from heavy ion beam losses.

    Full Text Available Background: Alopecia areata (AA is an autoimmune disease mediated by T lymphocytes. Many treatments have been used but their results remain disappointing. There is a need to propose new therapeutic alternatives. Methods: During a period of 3 years, 26 patients with recalcitrant or severe AA (>40% hair loss were enrolled in an open-label uncontrolled clinical trial. According to the response to sulfasalazine, patients were grouped into 3 categories: no hair regrowth (< 10% terminal hair, partial hair regrowth (10%-90% terminal hair, and complete hair regrowth (90%-100% terminal hair. Efficacy evaluation was performed with clinical examination. Results: Twenty-two patients completed the treatment. Overall, 68.2% (15 of 22 patients responded to therapy: 27.3% (6 of 22 patients achieved complete hair regrowth, and 40.9% had partial hair regrowth. Seven (31.8% patients had no hair regrowth. Of the 22 patients with complete and partial remission, 10 (45.5% suffered a partial or complete relapse. Side effects following treatment were seen in 7 (31.8% patients. Conclusion: Sulfasalazine could be considered as a therapeutic alternative in the treatment of AA, because of its safety profile, cosmetically acceptable efficacy, and good tolerability.

    Full Text Available Pseudo-Foster Kennedy Syndrome is described as unilateral optic disc swelling with contra lateral optic atrophy in the absence of an intracranial mass causing compression of the optic nerve. This occurs typically due to bilateral sequential optic neuritis or ischemic optic neuropathy. We describe a case of pseudo-Foster Kennedy Syndrome in a 37-year-old male with unilateral papilledema secondary to malignant hypertension and pre-existing ischemic optic neuropathy in other eye preventing transmission of raised intracranial pressure to the optic nerve. Hypertension and diabetes mellitus (DM play a significant role in pathogenesis of ischemic optic neuropathy. There is a greater correlation in patients with small disc and little to no cupping. The disorder commonly occurs in the 40-65 yrs age group. Our case is an example of Pseudo-Foster Kennedy syndrome where papilledema in one eye was associated with uncontrolled hypertension and disc pallor in fellow eye was secondary to ischemic optic neuropathy.

  6. Binary Large Object-Based Approach for QR Code Detection in Uncontrolled Environments

    2017-01-01

    Full Text Available Quick Response QR barcode detection in nonarbitrary environment is still a challenging task despite many existing applications for finding 2D symbols. The main disadvantage of recent applications for QR code detection is a low performance for rotated and distorted single or multiple symbols in images with variable illumination and presence of noise. In this paper, a particular solution for QR code detection in uncontrolled environments is presented. The proposal consists in recognizing geometrical features of QR code using a binary large object- (BLOB- based algorithm with subsequent iterative filtering QR symbol position detection patterns that do not require complex processing and training of classifiers frequently used for these purposes. The high precision and speed are achieved by adaptive threshold binarization of integral images. In contrast to well-known scanners, which fail to detect QR code with medium to strong blurring, significant nonuniform illumination, considerable symbol deformations, and noising, the proposed technique provides high recognition rate of 80%–100% with a speed compatible to real-time applications. In particular, speed varies from 200 ms to 800 ms per single or multiple QR code detected simultaneously in images with resolution from 640 × 480 to 4080 × 2720, respectively.

    Background Conjunctival pyogenic granulomas are commonly seen after ocular surgeries or at an ocular wound site. The aim of this study is to describe a novel histological classification for medically uncontrolled conjunctival pyogenic granulomas (MUCPG), and to explore whether the diversity in clinical features correlates to different histological subtypes of MUCPG. Methods This is an observational cross-section case series. We reviewed 46 consecutive patients with conjunctival pyogenic granulomas who did not respond to topical corticosteroids and underwent surgical excision from January 1, 2006 through December 31, 2015. Clinical features and histological findings were presented and analyzed. Results Ocular surgery, accidental injury, and chalazion were the main predisposing causes of MUCPG. The lesions tended to occur unilaterally on the bulbar conjunctiva. Forty patients (87%) presented an enrichment of inflammatory cells and proliferated capillaries in their pathological sections (inflammatory pattern). Six patients (13%) showed relatively few inflammatory cells and capillaries within fibrous stroma (fibrous pattern). Patients with the inflammatory pattern were older (p = 0.025) and tended to be located in bulbar conjunctiva (p = 0.002). The predisposing causes were also different between two histological subtypes (p = 0.007). Conclusions We found the correlation between clinical presentation and histological subtypes in patients with MUCPG, indicating this disease may need a new classification scheme. PMID:28008138

    The Basel Convention on the Control of Transboundary Movement of Hazardous Wastes and their Disposal was adopted on March 22, 1989 and enforced on May 5, 1992. Since then, the USA, one of the world's largest e-waste producers, has not ratified this Convention or the Basel Ban Amendment. Communities are still debating the legal loophole, which permits the export of whole products to other countries provided it is not for recycling. In January 2011, China's WEEE Directive was implemented, providing stricter control over e-waste imports to China, including Hong Kong, while emphasizing that e-waste recycling is the producers' responsibility. China is expected to supersede the USA as the principal e-waste producer, by 2020, according to the UNEP. Uncontrolled e-waste recycling activities generate and release heavy metals and POPs into the environment, which may be re-distributed, bioaccumulated and biomagnified, with potentially adverse human health effects. Greater efforts and scientific approaches are needed for future e-product designs of minimal toxic metal and compound use, reaping greater benefits than debating the definition and handling responsibilities of e-waste recycling.

    Directory of Open Access Journals (Sweden)

    Ana Cristina Pelosi

    2014-12-01

    Full Text Available The present paper reports on partial findings of a major research project entitled Interdisciplinary project on social cognitive representations in the conceptualization of violence in urban Brazilian centers. It aims at providing some insight into an embodied and social-culturally situated concept of representation – a social cognitive representation, as I understand it, by presenting both a theoretic-philosophical basis for this kind of concept as well as some preliminary findings of an analysis of focus groups talks about urban violence. The methodology is focused on discursive and cognitive aspects which emerge from and influence people’s verbal interactions. The qualitative analysis performed suggests, among others not discussed here, the emergence of two metaphors in participants’ talks: VIOLENCE IS A PRODUCT MANUFACTURED BY THE MEDIA and VIOLENCE IS A SPREADING CONTAGIOUS DISEASE. This appears to be due to the Media’s sensationalist trivialization of violence which results in violence being thought of as present anywhere and everywhere like an UNCONTROLLED FORCE. The trivialization of violence by the Media contributes to negative attitudes and feelings of lack of control, distrust, prejudice and hurt.

    This quasi-experimental study examined the effectiveness of a behavior modification program for diabetic control in Thai elders with uncontrolled Type 2 Diabetes. Purposive sampling was used to select 30 elders from one community as an intervention group, and 30 from a neighboring community as a control group. The intervention group participated in a program of 12 weeks' duration involving activities related to group counseling, group discussion, and an empowerment process that enhanced appropriate consumption of healthy diet, medication taking, and exercise. Data were collected by interviews using a questionnaire to assess knowledge of diabetes, perceived self-efficacy, and diabetes control behavior, including fasting blood glucose and glycosylated hemoglobin, were examined at the baseline and three months thereafter. At program completion, the intervention group had significantly higher scores of knowledge, self-efficacy, and health behaviors than those in the control group, but blood glucose and glycosylated hemoglobin were not significantly different. Although nurses can use aspects of this program to benefit elders with diabetes who require support and education, further research is required to provide improved health outcomes such as better glycemic control. © 2013 Wiley Publishing Asia Pty Ltd.

    Fibromyalgia can affect the control of asthma when both diseases are present in a single patient. To characterize asthma in patients with concomitant fibromyalgia to assess whether fibromyalgia is an independent factor of asthma severity that influences poor asthma control. We also evaluated how dyspnea is perceived by patients in order to demonstrate that alterations in the perception of airway obstruction may be responsible for poor asthma control. This was a cross-sectional case-control multicenter study, in which 56 patients in the asthma and fibromyalgia group were matched to 36 asthmatics by sex, approximate age, and asthma severity level. All patients were women. Study variables included the Asthma Control Test (ACT), the Mini Asthma Quality of Life Questionnaire (MiniAQLQ), the Nijmegen hyperventilation syndrome questionnaire, the Hospital Anxiety and Depression Scale, and perception of dyspnea after acute bronchoconstriction. Although patients in both study groups showed similar asthma severity and use of anti-asthmatic drugs, patients in the asthma and fibromyalgia group showed lower scores on the ACT and MiniAQLQ questionnaires, and higher scores of anxiety and depression as well as hyperventilation compared to asthma patients without fibromyalgia. All these differences were statistically significant. Fibromyalgia in patients with asthma influences poor control of the respiratory disease and is associated with altered perception of dyspnea, hyperventilation syndrome, high prevalence of depression and anxiety, and impaired quality of life. Fibromyalgia may be considered a risk factor for uncontrolled asthma in patients suffering from asthma and fibromyalgia concomitantly.

    2017-04-01

    Poor adherence with pharmacotherapy is well recognised as one of the main barriers to achieving satisfactory blood pressure control, although accurately measuring patient adherence has historically been very challenging. Urine analysis by high-performance liquid chromatography-tandem mass spectrometry has recently become routinely available as a method of screening for non-adherence. In addition to measuring rates of adherence in hypertensive patients, this study aimed to investigate the reasons for non-adherence given by patients and how patients react when they are informed of their results. This was a retrospective observational study looking at results from the routine use of this assay in a specialist hypertension clinic in Birmingham, UK, in patients with uncontrolled hypertension and those under consideration for renal denervation. Out of the 131 patients analysed, only 67 (51%) were taking all their medications as prescribed. Forty-three patients (33%) were taking some of their medications, whilst 21 patients (16%) were completely non-adherent. The most common reasons cited for non-adherence were adverse effects of medication and forgetfulness. Adherence rates for thiazide/thiazide-like diuretics and spironolactone were lower than for other classes of antihypertensive drug. Despite the objective nature and high sensitivity of the test, 36% of non-adherent patients disputed the results. A minority of patients did not attend follow-up. Further research investigating the implications of a 'non-adherence' result on the patient-clinician relationship is required.

    This paper reviews the concentrations of persistent organic pollutants such as flame retardants (PBDEs), dioxins/furans (PCDD/Fs), polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and heavy metals/metalloid concentrations of different environmental media at Guiyu, a traditional rice-growing village located in southeastern Guangdong Province (PR China), which has turned into an intensive electronic-waste (e-waste) recycling site. Incomplete combustion of e-waste in open air and dumping of processed materials are the major sources of various toxic chemicals. By comparing with existing data available in other areas and also guidelines adopted in different countries, it is obvious that the environment is highly contaminated by these toxic chemicals derived from the recycling processes. For example, the monthly concentration of the sum of 22 PBDE congeners contained in PM{sub 2.5} (16.8 ng m{sup -3}) of air samples at Guiyu was 100 times higher than published data. In order to safeguard the environment and human health, detailed investigations are urgently needed, especially on tracking the exposure pathways of different toxic chemicals which may affect the workers and local residents especially mothers, infants and children. - Uncontrolled e-waste recycling is ruining the environment.

    Full Text Available Ear detection is an important step in ear recognition approaches. Most existing ear detection techniques are based on manually designing features or shallow learning algorithms. However, researchers found that the pose variation, occlusion, and imaging conditions provide a great challenge to the traditional ear detection methods under uncontrolled conditions. This paper proposes an efficient technique involving Multiple Scale Faster Region-based Convolutional Neural Networks (Faster R-CNN to detect ears from 2D profile images in natural images automatically. Firstly, three regions of different scales are detected to infer the information about the ear location context within the image. Then an ear region filtering approach is proposed to extract the correct ear region and eliminate the false positives automatically. In an experiment with a test set of 200 web images (with variable photographic conditions, 98% of ears were accurately detected. Experiments were likewise conducted on the Collection J2 of University of Notre Dame Biometrics Database (UND-J2 and University of Beira Interior Ear dataset (UBEAR, which contain large occlusion, scale, and pose variations. Detection rates of 100% and 98.22%, respectively, demonstrate the effectiveness of the proposed approach.

    While a huge amount of information about biological literature can be obtained by searching the PubMed database, reading through all the titles and abstracts resulting from such a search for useful information is inefficient. Text mining makes it possible to increase this efficiency. Some websites use text mining to gather information from the PubMed database; however, they are database-oriented, using pre-defined search keywords while lacking a query interface for user-defined search inputs. We present the PubMed Abstract Reading Helper (PubstractHelper) website which combines text mining and reading assistance for an efficient PubMed search. PubstractHelper can accept a maximum of ten groups of keywords, within each group containing up to ten keywords. The principle behind the text-mining function of PubstractHelper is that keywords contained in the same sentence are likely to be related. PubstractHelper highlights sentences with co-occurring keywords in different colors. The user can download the PMID and the abstracts with color markings to be reviewed later. The PubstractHelper website can help users to identify relevant publications based on the presence of related keywords, which should be a handy tool for their research. http://bio.yungyun.com.tw/ATM/PubstractHelper.aspx and http://holab.med.ncku.edu.tw/ATM/PubstractHelper.aspx.

  19. [Considerations on the guilt feelings towards mother and maternal separation using the Japanese keywords "sumu-akirameru" and "sumanai"].

    In this paper, I use the Japanese keywords "Sumanai" and "Sumu-Akirameru" to discuss the guilt feelings towards mother and maternal separation. "Sumanai" is an everyday Japanese expression signifying both a regretful apology and an obsessive compulsive feeling. The Japanese frequently say "Sumanai" to express their guilt feeling towards a dependent object. Clinical observation has shown me that "Sumanai" implies not only pathological guilt but also a more healthy contrite feeling, two sides of "Sumanai" which correspond to the persecutory guilt and depressive guilt described by L. Grinberg. In therapy, patients passing through the depressive position experience a kind of protective harmonious space. This experience of space associated with object loss is similar to potential space (D.W. Winnicott) or philobatism (M. Balint), and can be expressed by the Japanese term "Sumu-Akirameru". "Sumu" means clean, pure and "to take root". "Akirameru" means both "to abandon" and "to see calmly". "Sumanai" is the negative of "Sumu" and its pathological guilt feeling implies a sense of impurity. I have discovered close resemblances between "Sumu-Akirameru" and philobatism (M. Balint): 1) both are observed in the therapeutic depressive position; 2) both have an affinity for friendly expanses while simultaneously tending to avoid the external object; 3) both have a visual attribute and insight; 4) both have the special qualities of "submerging in" and "taking root", allowing patients to awaken their sense of self in this protective harmonious space; 5) both imply that the time is ripe for psychological change; 6) both involve a kind of complexity constituted of a regressive element and adaptability contrary to reality. As described above, "Sumu-Akirameru" as a psychotherapeutic phenomenon has many universal characteristics. On the other hand, there are several differences between "Sumu-Akirameru" and philobatism, differences deeply rooted in Japanese culture: 1) "Sumu

    Full Text Available Atopic bronchial asthma (ABA is a multifactorial disease; its development is dependent on many environmental and genetic factors. Genetic risk factors can affect the clinical phenotype of ABA and the level of therapeutic control over the disease. Cytokine genes are crucially important in pathogenesis of ABA as they encode proteins participating in immune response and development of inflammation in bronchi. It was suggested that the therapeutic control of the disease is genetically mediated and depends on the presence of one or another allele in genes of mediators, participating in ABA pathogenesis. The knowledge about genetic markers will allow to predict clinical course of ABA in children. We carried out the analysis of association between genes of pro- and anti-inflammatory cytokines with the level of therapeutic control of ABA. In children with controlled and uncontrolled ABA (CABA and UABA, respectively; n = 110, and in general a population sample (n = 138, we analysed 11 polymorphisms: IL2 (rs2069762, IL4 (rs2070874 и rs2243250, IL5 (rs2069812, IL10 (rs1800872 and rs1800896, IL12B (rs3212227, TNFA (rs1800629 and rs1800630, TGFB1 (rs1800469, and IFNG (rs2069705, encoding cytokines actively participating at the development of allergic inflammation. According to results of present study, the prevalence of alleles and genotypes of the analysed loci in the East Siberia Caucasians is consistent with the data in other world Caucasian populations. We have found statistically significant differences between UABA and control groups for the prevalence of IL2 (rs2069762 polymorphism: GG genotype was more common in control group (14.1% compared to 5.9%, р = 0.03. It was shown that the IL2*T allele and ТТ genotype of the rs2069762 are associated with the increased risk of uncontrolled ABA. A comparison of the haplotypes of IL4 (rs2070874 and rs2243250 gene with correction for sex and age within an additive model revealed that the most common

    Hypertension was both a mutual cause and the main concern of chronic kidney disease (CKD). Blood pressure control is more problematic in the company of CKD. This study compares the effects of renal sympathetic denervation (RSD) on 24-h ambulatory blood pressure measurements (ABPM) and renal function in individuals with CKD and uncontrolled hypertension by unlike a number of ablated spots using the EnligHTN catheter and the standard irrigated cardiac ablation catheter (SICAC), Flexability. The 112 subjects were randomly divided into two groups according to the catheter that would be used in the procedure EnligHTN (n=56) or Flexability (n=56). Into each group, we created 5 subgroups according to the number of ablated spots: 4, 8, 12, 16 and 20. All of them were followed for exactly 6 months to assess all the parameters measured in this investigation. Comparing the Δ 24-h systolic ABPM according to the number of ablated spots 4 and 20 for EnligHTN vs. Flexability, respectively, the differences were: -3.6±0.9 vs. -6.3±1.4mmHg (P<0.0001), and -13.9±4.8 vs. -36.3±4.3mmHg (P<0.0001). The comparisons between Δ estimated glomerular filtration rate (eGFR) according to the number of ablated spots 4 and 20 for EnligHTN vs. Flexability, respectively, were: +2.7±4.0 vs. +6.0±8.4mL/min/1.73m2 (P=0.2287), and +11.9±6.0 vs. +21.4±8.7mL/min/1.73m2 (P=0.0222). The RSD reduced the mean 24-h ABPM in subjects with CKD and uncontrolled hypertension and improved the renal function in both groups. These effects were more marked and important in subgroups underwent a great number of ablated spots using the SICAC. Copyright © 2017 SEH-LELHA. Publicado por Elsevier España, S.L.U.

    Asthma disproportionately affects children living in impoverished communities; however, factors related to asthma morbidity among impoverished rural children have not been adequately described. To examine factors associated with asthma morbidity among rural children living in the Arkansas Delta region. We performed a cross-sectional investigation of 109 rural children with asthma enrolled in public schools in the Arkansas Delta region. A questionnaire format and home inspection were used to examine participant, caregiver, and home characteristics. The median age of the study participants was 9 years, 83% were African American, and 71% had an annual household income of $20,000 or less. Ninety-eight percent of participants were insured, and most fit the criteria for uncontrolled asthma, yet only 23% reported taking inhaled corticosteroids. Transportation problems were cited by 20%. In the past 4 weeks, more than 50% reported rescue medication use or exercise limitations of 2 or more days per week or nocturnal symptoms of more than 2 nights per month. Emergency department visits in the past 6 months were reported by 28%, and 43% reported an unscheduled physician's visits for asthma in the past 3 months. Sixty-four percent had 1 or more positive allergen skin test results, and allergic sensitization was associated with exposure to dust mite, dog, mouse, and cockroach allergens in the home. Asthma morbidity was high among this cohort of atopic asthmatic children in the Arkansas Delta. Overuse of rescue medications and underuse of inhaled corticosteroids were prevalent even though the population was highly insured and had frequent health care use. Future asthma health initiatives should focus on the unique challenges associated with translating national guidelines-based care to rural pediatric populations. clinicaltrials.gov Identifier: NCT00590304.

    Recent interest in the antidepressant and anti-stress effects of subanesthetic doses of ketamine, an NMDA receptor antagonist, has identified mechanisms whereby ketamine reverses the effect of stress, but little is known regarding the prophylactic effect ketamine might have on future stressors. Here we investigate the prophylactic effect of ketamine against neurochemical and behavioral changes that follow inescapable, uncontrollable tail shocks (ISs) in Sprague Dawley rats. IS induces increased anxiety, which is dependent on activation of serotonergic (5-HT) dorsal raphe nucleus (DRN) neurons that project to the basolateral amygdala (BLA). Ketamine (10 mg/kg, i.p.) administered 2 h, 1 week, or 2 weeks before IS prevented the increased extracellular levels of 5-HT in the BLA typically produced by IS. In addition, ketamine administered at these time points blocked the decreased juvenile social investigation produced by IS. Microinjection of ketamine into the prelimbic (PL) region of the medial prefrontal cortex duplicated the effects of systemic ketamine, and, conversely, systemic ketamine effects were prevented by pharmacological inhibition of the PL. Although IS does not activate DRN-projecting neurons from the PL, IS did so after ketamine, suggesting that the prophylactic effect of ketamine is a result of altered functioning of this projection. SIGNIFICANCE STATEMENT The reported data show that systemic ketamine, given up to 2 weeks before a stressor, blunts behavioral and neurochemical effects of the stressor. The study also advances understanding of the mechanisms involved and suggests that ketamine acts at the prelimbic cortex to sensitize neurons that project to and inhibit the DRN. PMID:26740657

    One way to control the traffic at busy intersections is to construct a roundabout or rotary intersection, which is a special type of at-grade intersection, where all converging vehicles are forced to move round a central island in clock-wise direction. The present study aims to design a rotary for an uncontrolled multi leg intersection located in Royapetah in Chennai, India. The intersection has five approach roads with two-way traffic in all the approach roads and there is no signal or traffic police to control the traffic at present and hence experiences traffic chaos during peak hours. In order to design the rotary, it is essential to have the information on traffic volumes coming from the approach roads. For this, a video data collection was carried out for a duration of eight hours from 7.30 am to 11.30 am and from 2.30 pm to 6.30 pm on a typical working day using a handycam from the terrace of an apartment building located near the intersection. During data extraction stage, each 5 min. traffic volume was extracted for all the five classes of vehicles considered and were converted to passenger car units (PCU). The analysis of traffic data showed that during peak hour from 4.45 pm to 5.45 pm, the proportion of weaving traffic, i.e., ratio of sum of crossing streams to the total traffic on the weaving section was found to be 0.81. According to Indian road congress (IRC) guidelines, this proportion can take any value between 0.4 and 1 and in the present study, the calculated value is found to be within the prescribed range. Using the calculated values of average entry width of the rotary and width & length of weaving section, the practical capacity of the rotary was found to be 3020 PCUs which is well above the observed traffic volume of 2665 PCUs.

    Intra-abdominal packing is a possible option for persistent bleeding following hysterectomy for postpartum hemorrhage. However, to date, only very limited data about maternal outcome after intra-abdominal packing for surgically uncontrolled hemorrhage following hysterectomy are available. The objective of the current study was to estimate maternal outcome after intra-abdominal packing following unsuccessful peripartum hysterectomy for postpartum hemorrhage. A questionnaire was mailed to all maternity units performing more than 850 deliveries per year. Inclusion criteria were: all cases of abdominal packing performed following unsuccessful peripartum hysterectomy for postpartum hemorrhage between 2003 and 2013. The primary outcome was success of intra-abdominal packing, defined as the arrest of hemorrhage with no need of additional procedure. The total number of deliveries during the study period that occurred in the 51 participating centers was 1,430,142. The centers reported a total of 718 (1 per 2000 deliveries) peripartum hysterectomies for PPH and 53 abdominal packings performed after unsuccessful peripartum hysterectomy (about 1 per 14 hysterectomies). A median of 5 [IQR 3-7] pads were used for packing. Abdominal packing was removed after a median of 39.5 hours [IQR 24-48]. The success rate of abdominal packing was 62% (33/53). Among the 20 (38%) women in whom bleeding did not stop following the use of abdominal packing, 6 required a second surgical intervention, 6 a pelvic artery embolization and the 8 other women had "only" further intensive resuscitation and pharmacological treatments. Finally, mortality rate was 24% (13/53). Our results suggest that abdominal packing, used for duration of 24 to 48 hours, seems to be an option as an ultimate procedure to control persistent life-threatening postpartum hemorrhage following peripartum hysterectomy.

    We have reconstructed the uncontrolled rotational motion of the Progress M-29M transport cargo spacecraft in the single-axis solar orientation mode (the so-called sunward spin) and in the mode of the gravitational orientation of a rotating satellite. The modes were implemented on April 3-7, 2016 as a part of preparation for experiments with the DAKON convection sensor onboard the Progress spacecraft. The reconstruction was performed by integral statistical techniques using the measurements of the spacecraft's angular velocity and electric current from its solar arrays. The measurement data obtained in a certain time interval have been jointly processed using the least-squares method by integrating the equations of the spacecraft's motion relative to the center of mass. As a result of processing, the initial conditions of motion and parameters of the mathematical model have been estimated. The motion in the sunward spin mode is the rotation of the spacecraft with an angular velocity of 2.2 deg/s about the normal to the plane of solar arrays; the normal is oriented toward the Sun or forms a small angle with this direction. The duration of the mode is several orbit passes. The reconstruction has been performed over time intervals of up to 1 h. As a result, the actual rotational motion of the spacecraft relative to the Earth-Sun direction was obtained. In the gravitational orientation mode, the spacecraft was rotated about its longitudinal axis with an angular velocity of 0.1-0.2 deg/s; the longitudinal axis executed small oscillated relative to the local vertical. The reconstruction of motion relative to the orbital coordinate system was performed in time intervals of up to 7 h using only the angularvelocity measurements. The measurements of the electric current from solar arrays were used for verification.

    Uncontrolled confounding by personal exposures like smoking can limit the inferential power of occupational cohort studies. We developed and demonstrate a refinement of an existing type of sensitivity analysis, indirect adjustment, for evaluating the potential magnitude of confounding by alcohol and tobacco. Results of a large retrospective cohort study of laryngeal cancer and exposure to metalworking fluids (MWF) are used to illustrate the methods. Data on smoking and drinking habits representative of the study cohort were obtained from a sample of US manufacturing workers from the 1977 National Health Interview Survey (NHIS). Two different mechanisms were assumed to affect the distribution of confounding factors between MWF exposure groups: socially determined and chance differences. Chance variation was investigated with Monte Carlo sampling from the NHIS survey distribution of smoking and drinking. An upper bound on systematic differences in smoking and drinking was set by assuming that differences between exposure groups within the same unionized blue collar workforce were very unlikely to be larger than differences between blue and white collar manufacturing workers in the NHIS data. Under plausibly large differences in smoking and drinking habits among MWF exposure groups occurring by either mechanism, the exposure-risk association was unlikely to have been over- or under-estimated by as much as 20%. When comparing exposure groups within the same working population, it is unlikely that either systematic or chance differences in smoking and drinking habits will cause as much as a 20% change in the relative risk in large studies. While this study focused on an occupational exposure and laryngeal cancer, there are many situations in which epidemiologists are concerned that unmeasured 'lifestyle factors' may differ among exposure groups, and it would appear that the likely confounding effect of such differences will often be modest.

    The key risk analysis technologies for the re-entry of space objects into Earth’s atmosphere are divided into four categories: cataloguing and databases of the re-entry of space objects, lifetime and re-entry trajectory predictions, break-up models after re-entry and multiple debris distribution predictions, and ground impact probability models. In this study, we focused on re- entry prediction, including orbital lifetime assessments, for space situational awareness systems. Re-entry predictions are very difficult and are affected by various sources of uncertainty. In particular, during uncontrolled re-entry, large spacecraft may break into several pieces of debris, and the surviving fragments can be a significant hazard for persons and properties on the ground. In recent years, specific methods and procedures have been developed to provide clear information for predicting and analyzing the re-entry of space objects and for ground-risk assessments. Representative tools include object reentry survival analysis tool (ORSAT) and debris assessment software (DAS) developed by National Aeronautics and Space Administration (NASA), spacecraft atmospheric re-entry and aerothermal break-up (SCARAB) and debris risk assessment and mitigation analysis (DRAMA) developed by European Space Agency (ESA), and semi-analytic tool for end of life analysis (STELA) developed by Centre National d’Etudes Spatiales (CNES). In this study, various surveys of existing re-entry space objects are reviewed, and an efficient re-entry prediction technique is suggested based on STELA, the life-cycle analysis tool for satellites, and DRAMA, a re-entry analysis tool. To verify the proposed method, the re-entry of the Tiangong-1 Space Lab, which is expected to re-enter Earth’s atmosphere shortly, was simulated. Eventually, these results will provide a basis for space situational awareness risk analyses of the re-entry of space objects.

  9. Behavior of two-wheelers at limited priority uncontrolled T-intersections

    Full Text Available Being convenient and affordable, motorized two-wheeler is the most widely used personal mode for short and medium distance trips in India, thereby resulting in a very high concentration of two-wheelers on Indian roads. Its compact size and aggressive nature of two-wheeler riders have significant impact on the overall traffic characteristics and safety. A large number of unsignalized intersections in India do not have stop or yield sign, and even if it exists, drivers in general do not follow the intended priorities. The combinations of these factors create complex conditions at unsignalized intersections. At some intersections, where the drivers clearly perceive major and minor roads, priority rules are followed to a certain extent. Such partially controlled intersections where limited priorities are observed are studied here. The focus of this paper is on analyzing and modeling gap acceptance behavior of two-wheelers at limited priority unsignalized T-intersections in India. The data collected at four intersections revealed that accepted gaps/lags follow lognormal distribution. Logit models are developed for major and minor road right turnings which show that the probability of accepting a gap is higher if the driver is young, the conflicting vehicle is a two-wheeler, or both. Critical gap values are estimated using Raff's method, lag method, Ashworth's method, logit method, and maximum likelihood method. These values vary from 2.38 to 3.06 s for major road right turning and 2.77 to 3.71 s for minor road right turning. The maximum likelihood method is found to give the most consistent values. The findings of this study are useful in developing performance and safety evaluation of uncontrolled intersections in India.

    One of the most common ways of capturing wide eld-of-view scenes is by recording panoramic videos. Using an array of cameras with limited overlapping in the corresponding images, one can generate good panorama images. Using the panorama, several immersive display options can be explored. There is a two fold synchronization problem associated to such a system. One is the temporal synchronization, but this challenge can easily be handled by using a common triggering solution to control the shutters of the cameras. The other synchronization challenge is the automatic exposure synchronization which does not have a straight forward solution, especially in a wide area scenario where the light conditions are uncontrolled like in the case of an open, outdoor football stadium. In this paper, we present the challenges and approaches for creating a completely automatic real-time panoramic capture system with a particular focus on the camera settings. One of the main challenges in building such a system is that there is not one common area of the pitch that is visible to all the cameras that can be used for metering the light in order to nd appropriate camera parameters. One approach we tested is to use the green color of the eld grass. Such an approach provided us with acceptable results only in limited light conditions.A second approach was devised where the overlapping areas between adjacent cameras are exploited, thus creating pairs of perfectly matched video streams. However, there still existed some disparity between di erent pairs. We nally developed an approach where the time between two temporal frames is exploited to communicate the exposures among the cameras where we achieve a perfectly synchronized array. An analysis of the system and some experimental results are presented in this paper. In summary, a pilot-camera approach running in auto-exposure mode and then distributing the used exposure values to the other cameras seems to give best visual results.

    Despite current treatments, more than half of patients with asthma are not controlled. The objective was to evaluate the correlation between control perceived by patients and physicians, compared with control evaluated according to criteria of the Spanish Guidelines for Asthma Management (GEMA), and to investigate the factors associated with that control. Multicenter, cross-sectional, observational study including 343 patients with severe persistent asthma according to GEMA criteria seen in the Department of Pulmonology and Allergology. The correlation between asthma control perceived by the patient, the physician and according to clinical judgment based on the GEMA criteria was calculated, and a multivariate analysis was used to determine variables related to the perception of asthma control. According to GEMA criteria, only 10.2% of patients were well controlled, 27.7% had partial control and 62.1% were poorly controlled. Both the physicians and the patients overestimated control: 75.8% and 59.3% of patients had controlled asthma according to the patient and the physician, respectively, and were not controlled according to GEMA (P<.0001). Patients with uncontrolled asthma according GEMA had higher body mass index (P=.006) and physical inactivity (P=.016). Factors associated with a perceived lack of control by both physicians and patients were: nocturnal awakenings (≥ 1 day/week), frequent use of rescue medication (≥ 5 days/week) and significant limitation in activities. Discrepant factors between physicians and patients were dyspnea and emergency room visits (patients only), FEV1 ≤ 80% and a poorer understanding of the disease by the patient (physicians only). Only 10% of patients with severe asthma evaluated in this study are controlled according to GEMA criteria. Patients and physicians overestimate control and the overestimation by patients is greater. Physical inactivity and obesity are associated with a lack of control according to GEMA. Copyright

    The Basel Convention on the Control of Transboundary Movement of Hazardous Wastes and their Disposal was adopted on March 22, 1989 and enforced on May 5, 1992. Since then, the USA, one of the world's largest e-waste producers, has not ratified this Convention or the Basel Ban Amendment. Communities are still debating the legal loophole, which permits the export of whole products to other countries provided it is not for recycling. In January 2011, China's WEEE Directive was implemented, providing stricter control over e-waste imports to China, including Hong Kong, while emphasizing that e-waste recycling is the producers' responsibility. China is expected to supersede the USA as the principal e-waste producer, by 2020, according to the UNEP. Uncontrolled e-waste recycling activities generate and release heavy metals and POPs into the environment, which may be re-distributed, bioaccumulated and biomagnified, with potentially adverse human health effects. Greater efforts and scientific approaches are needed for future e-product designs of minimal toxic metal and compound use, reaping greater benefits than debating the definition and handling responsibilities of e-waste recycling. - Highlights: ► We recommended to ban uses of deca-BDE in addition to penta- and octa-BDEs. ► We suggested to replace PVC in electronic products with non-chlorinated polymers. ► Spend less time on debating responsibilities and definition of e-waste and recycling. ► Proposed to work more on eliminating sources and potentials of toxic substances.

    In the United States, more than 115,000 patients are wait-listed for organ transplants despite that there are 12,000 patients each year who die or become too ill for transplantation. One reason for the organ shortage is that candidates for donation must die in the hospital, not the emergency department (ED), either from neurologic or circulatory-respiratory death under controlled circumstances. Evidence from Spain and France suggests that a substantial number of deaths from cardiac arrest may qualify for organ donation using uncontrolled donation after circulatory determination of death (uDCDD) protocols that rapidly initiate organ preservation in out-of-hospital and ED settings. Despite its potential, uDCDD has been criticized by panels of experts that included neurologists, intensivists, attorneys, and ethicists who suggest that organ preservation strategies that reestablish oxygenated circulation to the brain retroactively negate previous death determination based on circulatory-respiratory criteria and hence violate the dead donor rule. In this article, we assert that in uDCDD, all efforts at saving lives are exhausted before organ donation is considered, and death is determined according to "irreversible cessation of circulatory and respiratory functions" evidenced by "persistent cessation of functions during an appropriate period of observation and/or trial of therapy." Therefore, postmortem in vivo organ preservation with chest compressions, mechanical ventilation, and extracorporeal membrane oxygenation is legally and ethically appropriate. As frontline providers for patients presenting with unexpected cardiac arrest, emergency medicine practitioners need be included in the uDCDD debate to advocate for patients and honor the wishes of the deceased.

  14. Empirical Tests of the Predicted Footprint for Uncontrolled Satellite Reentry Hazards

    2011-01-01

    A number of statistical tools have been developed over the years for assessing the risk of reentering object to human populations. These tools make use of the characteristics (e.g., mass, material, shape, size) of debris that are predicted by aerothermal models to survive reentry. The statistical tools use this information to compute the probability that one or more of the surviving debris might hit a person on the ground and cause one or more casualties. The statistical portion of the analysis relies on a number of assumptions about how the debris footprint and the human population are distributed in latitude and longitude, and how to use that information to arrive at realistic risk numbers. Because this information is used in making policy and engineering decisions, it is important that these assumptions be tested using empirical data. This study uses the latest database of known uncontrolled reentry locations measured by the United States Department of Defense. The predicted ground footprint distributions of these objects are based on the theory that their orbits behave basically like simple Kepler orbits. However, there are a number of factors in the final stages of reentry - including the effects of gravitational harmonics, the effects of the Earth s equatorial bulge on the atmosphere, and the rotation of the Earth and atmosphere - that could cause them to diverge from simple Kepler orbit behavior and possibly change the probability of reentering over a given location. In this paper, the measured latitude and longitude distributions of these objects are directly compared with the predicted distributions, providing a fundamental empirical test of the model assumptions.

    Full Text Available Background: Factor VIIa (recombinant has an off-label use to control life-threatening bleeding that is refractory to other measures and was shown to decrease transfusion requirements. Objective: The primary objective of this study was to assess the safety and effectiveness of factor VIIa (recombinant on blood transfusion requirements and coagulation parameters when used in patients whose bleeding was uncorrected by other means. The pharmacoeconomic impact for any discrepancy from our protocol was evaluated. Secondary outcomes included 4-hour and 28-day mortality, as well as safety of this agent in terms of thromboembolic complications. Materials and Methods: We retrospectively evaluated patients who received recombinant-activated factor VII (rFVIIa for uncontrolled bleeding from June 2008 to April 2011. The medical records of 33 patients were evaluated. Coagulation parameters and blood products were determined 24 hours before and 24 hours after administration of rFVIIa, and the results compared. Patients were also screened for any thromboembolic complications. Results: Administration of rFVIIa reduced blood transfusion requirements and improved coagulation parameters significantly (P<0.05. No thromboembolic complications were reported. Most of the dosing was consistent with those recommended in our institutional protocol, with discrepancies resulting in an average cost of $56 058. Moreover, pH was reported in only 67% of patients. All patients treated with rFVIIa survived up to 4 hours after receiving this agent, while the 28-day mortality was 24% (8/33. Conclusion: The use of rFVIIa appears to be safe and effective in promoting hemostasis, as evident from reducing transfusion requirements and improving the coagulation variables.

  16. Counterfactual Reasoning for Regretted Situations Involving Controllable Versus Uncontrollable Events: The Modulating Role of Contingent Self-Esteem

    2015-01-01

    We report a study that examined the modulating impact of contingent self-esteem on regret intensity for regretted outcomes associated with controllable versus uncontrollable events. The Contingent Self-Esteem Scale (e.g., Kernis & Goldman, 2006) was used to assess the extent to which a person’s sense of self-worth is based on self and others’ expectations. We found that there was an influence of self-esteem contingency for controllable but not for uncontrollable regret types. For controllable regret types individuals with a high contingent (i.e., unstable) self-esteem reported greater regret intensity than those with a low contingent (i.e., stable) self-esteem. We interpret this finding as reflecting a functional and adaptive role of high contingent self-esteem in terms of mobilizing the application of counterfactual reasoning and planning mechanisms that can enable personal expectations to be achieved in the future.

    Studies conducted in Qatar have reported a high prevalence of diabetic nephropathy, retinopathy, and neuropathy. These complications are often associated with poor medication adherence and uncontrolled diabetes. The objectives of this study were to determine the rate of medication adherence among patients with uncontrolled diabetes, and to compare the characteristics and identified barriers between patients with good and those with poor medication adherence. A cross-sectional quantitative study was conducted among patients living in Qatar with uncontrolled diabetes attending primary healthcare clinics from October 2016 to January 2017. An interviewer-administered questionnaire comprising three sections was utilized in the study: patients' characteristics, Adherence to Refill and Medications Scale in Diabetes (ARMS-D), and barriers to medication adherence. ARMS-D is a validated tool that is used to identify adherence level among patients with diabetes. Descriptive and inferential statistics including regression analysis were used for data analysis. A total of 260 patients were included in the analysis. Overall, 73% (n=191) were nonadherent to their diabetes medications (ARMS-D score above 11). Nonadherent patients reported the majority of the pre-determined barriers to medication adherence with forgetfulness being the most commonly reported barrier. Multivariate linear regression analysis found age, ethnicity, education level, income level and HbA1c to be independent predictors of adherence. The findings of this study reaffirm the notion that non-adherence to medications among patients with uncontrolled diabetes within primary care setting is higher than the general diabetes population. This high prevalence is concerning and necessitates urgent interventions. Nonetheless, an in-depth understanding of barriers to medication adherence often requires qualitative research approach as these barriers are very complex and multifactorial in nature.

    Full Text Available Diabetic patients have higher risk of urinary tract infection (UTI. In the present study, we investigated the impact of glycemic control in diabetic patients on UTI prevalence, type of strains, and their antimicrobial drugs susceptibility. This study was conducted on urine samples from 722 adult diabetic patients from which 252 (35% samples were positive for uropathogens. Most UTI cases occurred in the uncontrolled glycemic group (197 patients versus 55 patients with controlled glycemia. Higher glycemic levels were measured in uncontrolled glycemia group (HbA1c = 8.3 ± 1.5 and 5.4 ± 0.4, resp., P<0.0001. Females showed much higher prevalence of UTI than males in both glycemic groups (88.5% and 11.5%, resp., P<0.0001. In the uncontrolled glycemia group 90.9% of the UTI cases happened at ages above 40 years and a clear correlation was obtained between patient age ranges and number of UTI cases (r=0.94; P=0.017, whereas in the group with controlled glycemia no trend was observed. Escherichia coli was the predominant uropathogen followed by Klebsiella pneumoniae and they were together involved in 76.2% of UTI cases. Those species were similarly present in both diabetic groups and displayed comparable antibiotic resistance pattern. These results highlight the importance of controlling glycemia in diabetic patients to reduce the UTI regardless of age and gender.

    To examine the outcomes of women in advanced shock from uncontrolled postpartum hemorrhage (PPH) who underwent placement of an Every Second Matters for Mothers and Babies Uterine Balloon Tamponade (ESM-UBT) device. In a prospective case series, data were collected for women who received an ESM-UBT device at healthcare facilities in Kenya, Senegal, Sierra Leone, and Tanzania between September 1, 2012, and September 30, 2016. Shock class was assigned on the basis of recorded blood pressures and mental status at the time of UBT placement. Data for 306 women with uncontrolled PPH from uterine atony across 117 facilities were analyzed. Normal vital signs or class I/II shock were reported for 166 (54.2%). In this group, one death occurred and was attributed to PPH (survival rate 99.4%). There were no cases of shock progression. One hundred and eleven (36.3%) were in class III shock and 29 (9.5%) in class IV shock; the respective survival rates were 97.3% (n=108) and 86.2% (n=25). The ESM-UBT device arrests hemorrhage, prevents shock progression, and is associated with high survival rates among women with uncontrolled PPH from uterine atony. © 2017 International Federation of Gynecology and Obstetrics.

  2. Out of control mortality matters: the effect of perceived uncontrollable mortality risk on a health-related decision

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available Prior evidence from the public health literature suggests that both control beliefs and perceived threats to life are important for health behaviour. Our previously presented theoretical model generated the more specific hypothesis that uncontrollable, but not controllable, personal mortality risk should alter the payoff from investment in health protection behaviours. We carried out three experiments to test whether altering the perceived controllability of mortality risk would affect a health-related decision. Experiment 1 demonstrated that a mortality prime could be used to alter a health-related decision: the choice between a healthier food reward (fruit and an unhealthy alternative (chocolate. Experiment 2 demonstrated that it is the controllability of the mortality risk being primed that generates the effect, rather than mortality risk per se. Experiment 3 showed that the effect could be seen in a surreptitious experiment that was not explicitly health related. Our results suggest that perceptions about the controllability of mortality risk may be an important factor in people’s health-related decisions. Thus, techniques for adjusting perceptions about mortality risk could be important tools for use in health interventions. More importantly, tackling those sources of mortality that people perceive to be uncontrollable could have a dual purpose: making neighbourhoods and workplaces safer would have the primary benefit of reducing uncontrollable mortality risk, which could lead to a secondary benefit from improved health behaviours.

    We evaluated how metabolic disorders affected antihypertension therapy. 2,912 rural Chinese patients with hypertension who provided blood samples, demographic and clinical data at baseline and after 1 year of antihypertension therapy were evaluated. At baseline, 1,515 patients (52.0%) were already receiving drug therapy and 11.4% of them had controlled blood pressure (BP). After 1 year, all 2,912 patients were receiving antihypertension therapy that was administered by community physicians, and 59.42% of them had controlled BP. Central obesity and abnormal triglyceride, high-density lipoprotein cholesterol, and glucose were associated with 15-70% higher risks of uncontrolled hypertension. Metabolic syndrome using the JIS criteria was associated with poor BP control (odds ratio: 1.71 and 1.54 for the baseline and follow-up datasets, respectively). The risk of uncontrolled hypertension increased with the number of metabolic disorders (p for trend antihypertension therapy, and all definitions of metabolic syndrome helped identify patients with elevated risks of uncontrolled hypertension.

    To assess the outcome of trabectome surgery in the treatment of glaucomatocyclitic crisis (Posner-Schlossman syndrome) in patients with uncontrolled intraocular pressure (IOP). Trabectome surgery was performed in seven patients with diagnosed glaucomatocyclitic crisis and uncontrolled IOP where cytomegalovirus DNA was verified by polymerase chain reaction in aqueous humour samples. All patients were treated with oral valganciclovir. After surgery the patients were followed-up for 12 months. Mean IOP before trabectome surgery was 40±10 mm Hg (range 33-58 mm Hg). The mean number of antiglaucoma medication prior to surgery was 3.1±0.4. By the end of the 12 months, IOP in all patients was reduced to normal level (13±1 mm Hg) and their antiglaucoma medication was decreased to 0.8±1.1. No recurring attack of glaucomatocyclitic crisis occurred. In addition to oral valganciclovir therapy, trabectome surgery seems to be a reliable and effective tool for the management of glaucomatocyclitic crisis with uncontrolled IOP.

    Acinetobacter baumannii, a substantial nosocomial pathogen, has developed resistance to almost all available antimicrobial drugs. Bacteriophage therapy is a possible alternative treatment for multidrug-resistant (MDR) bacterial infections. In this study, we have successfully isolated bacteriophage active against clinical strains of A. baumannii by enrichment from hospital sewage sludge using representatives of those strains. The bacteriophage isolated against A. baumannii formed plaques against beta-lactamases producing strains of A. baumannii. The utility of bacteriophage specific for A. baumannii to resolve wound infection in uncontrolled diabetic rats was evaluated. Five groups of uncontrolled diabetic rats were used. Group I was noninfected (Control), Group II was infected with MDR A. baumannii and challenged with bacteriophage, Group III was infected with MDR A. baumannii, Group IV was infected with MDR A. baumannii and challenged with antibiotic colistin, and Group V consisted of noninfected rats and sprayed with phage (Phage control). A significant decrease in infection, period of epithelization, and wound contraction was observed in the phage-challenged group when compared with antibiotic-treated uncontrolled diabetic rats and the control group. To conclude the study, new insights are provided into the biology of the broad host range of A. baumannii phage, demonstrating that A. baumannii phage has prospects for the treatment of infections caused by the MDR A. baumannii.

    Clinical and economic burden of patients with severe uncontrolled asthma (SUA) in a real-world managed-care setting required further documentation. The objective of this study was to determine the characteristics, clinical, and economic burden of SUA in a managed-care setting. This observational study identified patients with persistent asthma aged 12 years or more (N = 25,935) using the International Classification of Diseases, 9th Revision asthma codes and Healthcare Effectiveness Data and Information Set administrative criteria. An SUA subgroup was identified when all of the following 3 criteria were met in 2012: (1) 2 or more asthma exacerbations; (2) 6 or more medium- or high-dose dispensed canisters of inhaled corticosteroid (ICS) as monotherapy or with long-acting β2-agonist; and (3) 3 or more dispensed non-ICS controllers. Health care utilization and direct costs (all-cause and asthma-related) in 2013 were compared between SUA and non-SUA subgroups using multivariable regression. Compared with the non-SUA subgroup (N = 25,350, 97.7%), the SUA subgroup (N = 585, 2.3%) at baseline was significantly older and had more comorbidities, asthma specialist care, controller medication dispensed, and asthma exacerbations. During follow-up, patients with SUA exhibited significantly more asthma exacerbations and short-acting β2-agonist use, and higher all-cause and asthma-related costs than patients with non-SUA. The adjusted asthma-related average direct cost per patient at follow-up was significantly higher for SUA (mean ± SE) ($2325 ± $75) than non-SUA ($1261 ± $9) with an incremental cost of $1056 (95% CI, $907-$1205). Asthma drugs accounted for the major difference (incremental cost of $848/patient; 95% CI, $737-$959). Increases and disparities in health care utilization and direct cost by SUA status suggest that patients with SUA require more intensive therapy, greater attention to adherence and comorbidities, more specialist care, and, possibly

    To address the lung donor shortage, we obtained institutional review board and US Food and Drug Administration approval to transplant lungs recovered from uncontrolled donation after circulatory determination of death donors (uDCDDs). To compare outcomes of recipients of lungs recovered from uDCDDs vs. brain-dead donors. After consent and screening, lungs recovered from uDCDDs were assessed by 4 hours ex vivo lung perfusion (EVLP) and computed tomography (CT) scan. Over the course of 29 months, 502 potential uDCDDs younger than 66 years were identified in a single county, with death declaration by emergency medical services and four emergency departments in this and two other countries. We determined reasons that lungs from these uDCDDs were not able to be transplanted: uDCDDs could not have lungs recovered (224), next-of-kin could not be found or refused to discuss (67), next-of-kin refused (48), medical examiner case (39), logistics/missed (35), and miscellaneous (35). There were 247 medical contraindications: 141 pulmonary and 106 nonpulmonary. Lungs were recovered from 31 uDCDDs. Thirteen lungs did not have EVLP: 5 injured lungs (one pulmonary embolism [PE] with perforated infarct, two motor vehicle crash with severe injuries, one adhesion, and one lightning strike), two large PE, two prolonged ischemic time, two obvious chronic obstructive pulmonary disease, one technical, and one consent withdrawn. Eighteen lungs had EVLP: 10 with immediate edema (three PE, three unknown down time, three long ischemic time, and one ruptured aneurysm into L pleural space, making long cardiopulmonary resuscitation ineffective), and one myocarditis, possible lung involvement. In three lungs, CT showed edema after EVLP: one poor flush and poor EVLP performance, one edema after myocardial infarction (MI) with 10-year history of chronic heart failure, and one edema with MI, resuscitated, arrested again. One concurrent pneumonia was diagnosed by bronchoscopy, CT, and cultures; one

    The rate of type-2 diabetes mellitus (T2D) is dramatically increasing worldwide. Continuing diabetes mellitus (DM) care needs effective self-management education and support for both patients and family members. This study aimed to review and describe the impacts of diabetes mellitus self-management education (DSME) that involve family members on patient outcomes related to patient health behaviors and perceived self-efficacy on self-management such as medication adherence, blood glucose monitoring, diet and exercise changes, health outcomes including psychological well-being and self-efficacy, and physiological markers including body mass index, level of blood pressure, cholesterol level and glycemic control. Three databases, PubMed, CINAHL, and Scopus were reviewed for relevant articles. The search terms were “type 2 diabetes,” “self-management,” “diabetes self-management education (DSME),” “family support,” “social support,” and “uncontrolled glycaemia.” Joanna Briggs Institute (JBI) guidelines were used to determine which studies to include in the review. Details of the family support components of DSME intervention and the impacts of these interventions had on improving the health outcomes patients with uncontrolled glycaemia patients. A total of 22 intervention studies were identified. These studies involved different DSME strategies, different components of family support provided, and different health outcomes to be measured among T2D patients. Overall, family support had a positive impact on healthy diet, increased perceived support, higher self-efficacy, improved psychological well-being and better glycemic control. This systematic review found evidence that DSME with family support improved self-management behaviors and health outcomes among uncontrolled glycaemia T2D patients. The findings suggest DSME models that include family engagement can be a useful direction for improving diabetes care. PMID:28914815

    Diabetes mellitus is a chronic degenerative disease characterized by elevated hyperglycemia, triggering a series of processes and culminating in chronic, uncontrolled, cellular and vascular damage in different organs. To assess whether the elevated glycosylated hemoglobin, microalbuminuria, and the time evolution of more than 10 years of diabetes mellitus are associated with elevated resistance index of the interlobar renal arteries assessed with pulsed Doppler in patients with metabolic uncontrolled diabetes mellitus. Transversal-analytical, observational, prospective study that included diabetic patients attending UMAE abdominal ultrasound in 25 of IMSS, from October 15, 2014 to November 15, 2014, which was performed for pulsed Doppler index resistance of vascular interlobar renal arteries and was collected from electronic medical records: age, sex, glycated hemoglobin, and microalbuminuria. The association between metabolic uncontrolled diabetes mellitus was analyzed with the elevation of resistance index by χ(2) test or Fisher, being significant with a value of p < 0.05, and to assess the magnitude of the association that was measured with a response magnitude of 95%. 63 patients with type 2 diabetes were examined, with an average age of 52.3 ± 14.2 years, 41 were older than 50 years (65.0%), 26 with hypertension (41.2%), 32 with higher levels of glycated hemoglobin 7 (50.8%), 35 with normoalbuminuria (55.6%), 28 with microalbuminuria (44.4%), and 39 with a time evolution of diabetes of more than 10 years (61.9%). We observed a statistically significant difference between microalbuminuria and increased duration of diabetes mellitus with high resistance index. The alterations in renal microvasculature conditioned by the occurrence of microalbuminuria in diabetic nephropathy and the duration of diabetes are strongly associated with higher resistance index.

This study aimed to review and describe the impacts of diabetes mellitus self-management education (DSME that involve family members on patient outcomes related to patient health behaviors and perceived self-efficacy on self-management such as medication adherence, blood glucose monitoring, diet and exercise changes, health outcomes including psychological well-being and self-efficacy, and physiological markers including body mass index, level of blood pressure, cholesterol level and glycemic control. Three databases, PubMed, CINAHL, and Scopus were reviewed for relevant articles. The search terms were “type 2 diabetes,” “self-management,” “diabetes self-management education (DSME,” “family support,” “social support,” and “uncontrolled glycaemia.” Joanna Briggs Institute (JBI guidelines were used to determine which studies to include in the review. Details of the family support components of DSME intervention and the impacts of these interventions had on improving the health outcomes patients with uncontrolled glycaemia patients. A total of 22 intervention studies were identified. These studies involved different DSME strategies, different components of family support provided, and different health outcomes to be measured among T2D patients. Overall, family support had a positive impact on healthy diet, increased perceived support, higher self-efficacy, improved psychological well-being and better glycemic control. This systematic review found evidence that DSME with family support improved self-management behaviors and health outcomes among uncontrolled glycaemia T2D patients. The findings suggest DSME models that include family engagement can be a useful direction for improving diabetes care.

    Uncontrolled donation after cardiac death (DACD) has become an alternative to lung transplantation with encephalic-death donation. The main objective of this study is to describe the incidence of clinically relevant events in the period of thirty days after lung transplant with uncontrolled DACD and the influence of factors depending on the donor and donation process as well. Historical cohort study of 33 lung transplant receivers at Hospital Puerta de Hierro and Hospital Marqués de Valdecilla with 32 DACD from Hospital Clínico San Carlos from 2002 to 2008. We studied surgical and medical complications, primary graft dysfunction, acute rejection, pneumonia and mortality. We made an evaluation of the donor characteristics and donation procedure times (minutes). Median age of recipients was 50.5 years (interquartile range, 38.5-58). There were 28 males and 5 females. Cumulative incidence of events in the first month was: pneumonia 10 (31.3%); primary graft dysfunction 15 (46.9%); rejection 12 (37.5%); mortality 4 (12.1%); medical complications 25 (78.1%); and surgical complications 18 (56.3%). Median time of cardiac arrest was higher in those who presented pneumonia (15 vs. 7.5; p = 0.027). Median time of cold ischemia was higher in those who presented surgical complications and mortality (436 vs. 343.5; p = 0.04; 505 vs. 410; p = 0.033, respectively), and median of total ischemia times were longer in the recipients who died (828 vs. 695; p = 0.036). Uncontrolled DACD are a valid alternative for expanding the donor pool in order to mitigate the current shortage of lungs that are valid for transplantation. The incidence of complications is comparable with published data in the literature. Copyright © 2010 SEPAR. Published by Elsevier Espana. All rights reserved.

    Full Text Available We present a case of an 87-year-old female who was evaluated for an 8.5 cm left sided renal mass concerning for malignancy. The patient was transiently thrombocytopenic over the previous 4 months with platelet counts ranging from 50,000 to 125,000 plt/mcL and experienced diffuse hemorrhage during radical nephrectomy with failure to achieve mechanical hemostasis or fulguration. Following Surgicel (Ethicon; Somerville, New Jersey application, we applied Tisseel (Baxter; Deerfield, IL to the nephrectomy bed with complete hemostasis of bleeding foci. Tisseel saved this thrombocytopenic patient with uncontrolled bleeding and should have this clinical utility recognized.

    Full Text Available Memory plays an important role in most of Shakespeare’s plays. Shakespeare delves into the dark realms of human consciousness to reflect the disturbed minds and gnawing consciences of his characters with a profound psychological insight into the human psyche. Time, memory, madness and death seem to be the basic issues dealt with in his canon. My paper will address the uncontrollable mnemonic fragments within the human consciousness which reflect past traumas, fears and disturbances and will examine the cases of Ophelia and Lady Macbeth from a feminist reading of women.

    We report a case of Shigella flexneri serotype-2 causing bacteremia in an elderly gentleman with uncontrolled diabetes mellitus, who had no other apparent risk factors. Antibiotic susceptibility testing revealed that the organism was a multidrug resistant extended spectrum beta-lactamase producing straian, which was confirmed by molecular characterization. This rare case alerts both the clinician and microbiologist to a previously unaddressed risk factor of Shigella spp. causing bacteremia, as well as emerging resistant strains that are on the rise in immunocompromised patients.

However, there are no epidemiological data concerning this postural disorder. Defined by a posterior position of the centre of mass with respect to the base of support, backward disequilibrium is abnormal postural behavior, usually characterized by a posterior trunk tilt in standing and sitting positions, which predisposes subjects to backward falls. Many afflictions whether they are somatic (degenerative, ischemic and traumatic brain lesions, psychosomatic (psychomotor disadaptation syndrome, confinement to bed, nonuse situations or psychological (depression can cause backward disequilibrium. A vicious circle of falls, and loss of autonomy can arise and this is the main consequence of backward disequilibrium. Thus, in this paper, we review backward disequilibrium in elderly subjects with regard to the causes, consequences, assessment, and management.Keywords: backward disequilibrium, balance, elderly subject, falls, posture

    Full Text Available The low frequency error is a key factor which has affected uncontrolled geometry processing accuracy of the high-resolution optical image. To guarantee the geometric quality of imagery, this paper presents an on-orbit calibration method for the low frequency error based on geometric calibration field. Firstly, we introduce the overall flow of low frequency error on-orbit analysis and calibration, which includes optical axis angle variation detection of star sensor, relative calibration among star sensors, multi-star sensor information fusion, low frequency error model construction and verification. Secondly, we use optical axis angle change detection method to analyze the law of low frequency error variation. Thirdly, we respectively use the method of relative calibration and information fusion among star sensors to realize the datum unity and high precision attitude output. Finally, we realize the low frequency error model construction and optimal estimation of model parameters based on DEM/DOM of geometric calibration field. To evaluate the performance of the proposed calibration method, a certain type satellite’s real data is used. Test results demonstrate that the calibration model in this paper can well describe the law of the low frequency error variation. The uncontrolled geometric positioning accuracy of the high-resolution optical image in the WGS-84 Coordinate Systems is obviously improved after the step-wise calibration.

    The aim of this pilot study was to determine whether salivary alkaline phosphatase levels can be a non invasive marker for early inflammatory periodontal disease in children with uncontrolled type 1 diabetes mellitus. 10 healthy children (group 1), 10 children with recently diagnosed type 1 diabetes mellitus (group 2) and 10 children with type 1 diabetes mellitus for more than 4 years (group 3) were recruited for the study. All three groups were matched for age, gender and socioeconomic status. Periodontal health was assessed by plaque index, gingival index and probing pocket depth. Metabolic status was assessed by glycosylated hemoglobin levels, salivary alkaline phosphatase levels were determined by spectrophotometer. Data was analyzed by Kruskal Wallis ANOVA, Mann-Whitney U test and Spearman's rank correlation method. Salivary alkaline phosphatase levels correlated significantly with the periodontal parameters in the diabetic group. An increase in salivary alkaline phosphatase levels increased with increased values of gingival index and probing pocket depth. Group 3 showed greater correlation than group 2 and group 1. At p value pperiodontal disease parameters. Salivary alkaline phosphatase levels could be a useful tool in analyzing periodontal status of children with uncontrolled type I diabetes mellitus.

    Objective The goal of this pilot study was to determine the effects of short duration, intensive tango lessons on functional mobility in people with Parkinson disease. Design This study employed a within-subject, prospective, repeated measures design. Subjects/Patients Fourteen people with idiopathic Parkinson disease participated. Setting All balance and gait assessments were performed in a laboratory, but dance classes took place in a large, open classroom. Interventions Participants completed ten 1.5 hour long Argentine tango dance lessons within two weeks. Their balance, gait and mobility were assessed before and after the training sessions. Main Outcome Measures Measures included the Berg Balance Scale, the Unified Parkinson Disease Rating Scale, gait velocity, functional ambulation profile, step length, stance and single support percent of gait, Timed Up and Go, and the six minute walk. Results Participants significantly improved on the Berg Balance Scale (effect size (ES) = 0.83, p = 0.021), Unified Parkinson Disease Rating Scale Motor Subscale III (ES = −0.64, p = 0.029), and percent of time spent in stance during forward walking (ES = 0.97, p = 0.015). Non-significant improvements were noted on the Timed Up and Go (ES = −0.38, p = 0.220) and 6-minute walk (ES = 0.35, p = 0.170). Conclusions Frequent social dance lessons completed within a short time period appear to be appropriate and effective for these individuals with mild-moderately severe Parkinson disease.

    Physical activity has a positive impact on people's well-being, and it may also decrease the occurrence of chronic diseases. Activity recognition with wearable sensors can provide feedback to the user about his/her lifestyle regarding physical activity and sports, and thus, promote a more active lifestyle. So far, activity recognition has mostly been studied in supervised laboratory settings. The aim of this study was to examine how well the daily activities and sports performed by the subjects in unsupervised settings can be recognized compared to supervised settings. The activities were recognized by using a hybrid classifier combining a tree structure containing a priori knowledge and artificial neural networks, and also by using three reference classifiers. Activity data were collected for 68 h from 12 subjects, out of which the activity was supervised for 21 h and unsupervised for 47 h. Activities were recognized based on signal features from 3-D accelerometers on hip and wrist and GPS information. The activities included lying down, sitting and standing, walking, running, cycling with an exercise bike, rowing with a rowing machine, playing football, Nordic walking, and cycling with a regular bike. The total accuracy of the activity recognition using both supervised and unsupervised data was 89% that was only 1% unit lower than the accuracy of activity recognition using only supervised data. However, the accuracy decreased by 17% unit when only supervised data were used for training and only unsupervised data for validation, which emphasizes the need for out-of-laboratory data in the development of activity-recognition systems. The results support a vision of recognizing a wider spectrum, and more complex activities in real life settings.

    Pharmacological therapy for fibromyalgia syndrome (FMS) is actually unsatisfactory; analgetic and nonsteroidal anti-inflammatory drugs are not very effective. On the other hand, it is opportune to underline that antidepressant drugs produce positive response on pain in patients with FMS. Furthermore, many studies showed that using variable doses of melatonin (3-6 mg/d) in subjects affected from FMS had significantly been effective on pain, sleep, daytime fatigue, and depression. This study was aimed to evaluate the efficacy of agomelatine on depression, anxiety, cognition, and pain in a sample of drug-free FMS patients. Agomelatine was administered at the single daily dose of 25 mg/d to 15 fibromyalgia "drug-free" female subjects during 12 weeks. Outcome measures included the Hamilton Rating Scale for Depression, the Hamilton Rating Scale for Anxiety, the Zung Self-Rating Depression Scale, the Zung Self-Rating Anxiety Scale, the Visual Analog Scale of Pain, the Quality of Life Index, the Wisconsin Card Sorting Test, the Verbal Fluency Task-Controlled Oral Word Association Test, and the Stroop Color-Word Test. Treatment with agomelatine significantly improved depression, anxiety, and pain in patients with FMS. Regarding executive/cognitive symptoms, treatment with agomelatine did not have a significant impact on the explored neuropsychological domains, although there was a trend toward the improvement of performances. The findings showed that agomelatine was effective and well tolerated in patients with FMS. Further research is needed to fully evaluate the role of agomelatine as a potential pharmacological strategy for the treatment of FMS.

    A 29-year-old woman at 34 weeks' gestation with uncontrolled hyperthyroidism and thyrotoxic heart disease was admitted to urgency Cesarean section. After preoperative sedation and good communication, low-dose spinal anesthesia (7.5 mg 0.5 % bupivacaine) combined with epidural anesthesia (6 ml 2 % lidocaine) was performed through L3-4 inter-vertebral. Opioids were given intravenously to the mother for sedation after delivery of the baby. Satisfactory anesthesia and sedation was provided during surgery. The mother and the neonate were safe and no special complication was found after surgery. Our case demonstrated that low-dose spinal anesthesia combined with epidural anesthesia with intravenous opioids can provide satisfactory anesthesia and sedation, and reduce the risk of heart failure and thyroid storm.

    Full Text Available Hemophagocytic lymphohistiocytosis (HLH is a life-threatening, rapidly progressive hematologic disorder involving uncontrolled immune system activation. HLH has been associated with viral infections, including human immunodeficiency virus (HIV infections. We report a case of a critically ill 30-year-old female who was hospitalized with HIV-associated HLH, with a CD4 count of 4 cells/mL and HIV viral load of 1,842,730 copies/mL. After ruling out other potential infectious causes of HLH, antiretroviral therapy (ART was initiated with darunavir, ritonavir, tenofovir, and emtricitabine. Within one week of initiation of ART, the patient began to improve clinically and hematologically and was stable enough for discharge from the hospital three weeks after starting therapy. This case suggests that treatment with ART in patients with HIV-associated HLH should be considered even in critically ill patients with low CD4 counts.

    This study investigated the association between intermittent hypoxia and glycaemic control in patients with uncontrolled type 2 diabetes (T2D) not treated for sleep apnoea. This was a single-centre cross-sectional study of stable patients with T2D and HbA1c ≥7% (53 mmol/mol). Patients underwent overnight pulse oximetry and, if intermittent hypoxia-defined by a 4% oxyhaemoglobin desaturation index ≥15-was observed, respiratory polygraphy was performed. All participants completed the Pittsburgh Sleep Questionnaire and Hospital Anxiety and Depression Scale. The association between intermittent hypoxia and poorer glycaemic control (defined by an HbA1c level above the median of 8.5%) was estimated by multivariate logistic regression analysis. Out of 145 patients studied, 54 (37.2%) had intermittent hypoxia (with sleep apnoea confirmed in 53). Patients with intermittent hypoxia had 0.7% (7.7 mmol/mol) higher median HbA1c levels than patients without intermittent hypoxia (P=0.001). Intermittent hypoxia was associated with poorer glycaemic control after adjusting for obesity, age at onset and duration of diabetes, insulin requirement, sleep quality and depressive mood (OR: 2.31, 95% CI: 1.06-5.04, model adjusted for body mass index; OR: 2.46, 95% CI: 1.13-5.34, model adjusted for waist-to-height ratio). Intermittent hypoxia, a consequence of sleep apnoea, is frequent and has a strong independent association with poorer glycaemic control in patients with uncontrolled T2D.

    The aim of this study was to examine the effect of file type and activation time on the uncontrolled removal of dentin during in vitro ultrasonic irrigant activation in prepared curved root canals. Seventy-two curved mesial root canals of human mandibular molars were prepared to size 35/.04 taper. The specimens were randomly allocated to 4 groups (n = 18). Two milliliters of 2% sodium hypochlorite were delivered 3 times to each root canal, and the irrigant was ultrasonically activated every time for 10 seconds at 35% power either by a ultrasonic K-file (group A), an Irrisafe file (Acteon Satelec, Merignac, France) (group B), or a smooth wire (group C). The same specimens also received further activation continuously for another 30 seconds. No activation took place in group D. Specimens were scanned by micro-computed tomographic imaging before and after preparation and after the first and second activation period. Scans were coregistered and segmented, and the amount of dentin removed during activation was quantified by morphological operations. Results were analyzed by nonparametric statistical tests (α = 0.05). Defects with a maximum depth of 0.18 mm were identified. Both the type of file and activation time affected the removal of dentin (P ≤ .002 and P ≤ .031, respectively). K-files removed more dentin than Irrisafe files and smooth wires in the coronal and middle third. All files removed comparable amounts in the apical third. All 3 types of files may result in uncontrolled removal of dentin. A longer activation time may increase this effect. Copyright © 2016 American Association of Endodontists. Published by Elsevier Inc.

    Inhibition of the renin-angiotensin system is a widely accepted approach to treat immunoglobulin A (IgA) nephropathy, whereas the role of fish oils as a supplement is controversial. Tumor necrosis factor α (TNF-α) is considered to be involved in the pathophysiologic process of this disorder. Recent in vitro and clinical observations that wormwood can decrease TNF-α levels has led us to investigate the effect of wormwood as a supplement in patients with IgA nephropathy. Pilot uncontrolled trial. 10 patients with biopsy-proven IgA nephropathy, normal kidney function, and a history of at least 3 months of proteinuria with protein excretion > 500 mg/d and < 3,500 mg/d despite ongoing dual renin-angiotensin system blockade. The selected patients were given supplements of 1.8 g/d of thujone-free wormwood preparation for 6 months without discontinuing their renin-angiotensin system blockade. Proteinuria and blood pressure after intervention compared with baseline values. Monthly assessment of urine protein-creatinine ratio and blood pressure during the observation period. Urine protein-creatinine ratio decreased significantly from 2,340 ± 530 to 315 ± 200 mg/g at the end of the supplementation period (P < 0.001) and was stable during the supplement-free follow-up of another 6 months. Estimated glomerular filtration rate and endogenous creatinine clearance were unchanged during the entire study period. There was a moderate, but significant, decrease (P < 0.002) in mean arterial blood pressure. Open uncontrolled trial including a small number of patients. Thujone-free wormwood with its favorable safety profile can be an alternative supplement to manage proteinuria in patients with IgA nephropathy. Copyright © 2010 National Kidney Foundation, Inc.

    To compare the effectiveness of a nurse-led hypertension clinic with conventional community care in general practice in the management of uncontrolled hypertension in patients with type 2 diabetes. We studied 120 men and women outpatient attendees (61% non-Caucasian) with type 2 diabetes and a seated blood pressure (BP) >or=140/80 mmHg. All patients were being treated for hypertension, and 71% had increased urinary albumin excretion (UAE). Patients were allocated to either a nurse-led hypertension clinic or conventional primary care. The primary outcome measure was a change in systolic BP. Secondary outcome measures were total cholesterol, HDL cholesterol, total triglycerides, HbA(1c), UAE, serum creatinine, and changes in absolute stroke and coronary heart disease (CHD) risk scores. The mean (95% CI) difference in the decrement of systolic BP was 12.6 mmHg (5.9-19.3) (P = 0.000) in favor of the nurse-led group, whose patients were three times more likely to a reach target systolic BP <140 mmHg compared with conventional care (P = 0.003). A significant fall in 10-year CHD (P = 0.004) and stroke risk (P = 0.000) scores occurred only in the nurse-led group. There were no significant differences in the reduction of diastolic BP or any of the other secondary outcome measures at 6 months. Compared with conventional care, a nurse-led hypertension clinic is a more effective intervention for patients with type 2 diabetes and uncontrolled hypertension. A target systolic BP <140 mmHg is more readily achieved and may be associated with significant reductions in 10-year cardiovascular disease risk scores.

    Full Text Available Abstract Background Results of a national survey of asthmatic children that evaluated management goals established in 2004 by the National Asthma Education and Prevention Program (NAEPP indicated that asthma symptom control fell short on nearly every goal. Methods An Internet-based survey was administered to adult caregivers of children aged 6-12 years with moderate to severe asthma. Asthma was categorized as uncontrolled when the caregiver reported pre-specified criteria for daytime symptoms, nighttime awakening, activity limitation, or rescue medication based on the NAEPP guidelines. Children's health-related quality of life (HRQOL and caregivers' quality of life (QOL were assessed using the Child Health Questionnaire Parent Form 28 (CHQ-PF28 and caregiver's work productivity using a modified Work Productivity and Activity Impairment Questionnaire. Children with uncontrolled vs. controlled asthma were compared. Results 360 caregivers of children with uncontrolled asthma and 113 of children with controlled asthma completed the survey. Children with uncontrolled asthma had significantly lower CHQ-PF28 physical (mean 38.1 vs 49.8, uncontrolled vs controlled, respectively and psychosocial (48.2 vs 53.8 summary measure scores. They were more likely to miss school (5.5 vs 2.2 days, arrive late or leave early (26.7 vs 7.1%, miss school-related activities (40.6 vs 6.2%, use a rescue inhaler at school (64.2 vs 31.0%, and visit the health office or school nurse (22.5 vs 8.8%. Caregivers of children with uncontrolled asthma reported significantly greater work and activity impairment and lower QOL for emotional, time-related and family activities. Conclusions Poorly controlled asthma symptoms impair HRQOL of children, QOL of their caregivers, and productivity of both. Proper treatment and management to improve symptom control may reduce humanistic and economic burdens on asthmatic children and their caregivers.

    Full Text Available Abstract Background Biomedical researchers often want to explore pathogenesis and pathways regulated by abnormally expressed genes, such as those identified by microarray analyses. Literature mining is an important way to assist in this task. Many literature mining tools are now available. However, few of them allows the user to make manual adjustments to zero in on what he/she wants to know in particular. Results We present our software program, GenCLiP (Gene Cluster with Literature Profiles, which is based on the methods presented by Chaussabel and Sher (Genome Biol 2002, 3(10:RESEARCH0055 that search gene lists to identify functional clusters of genes based on up-to-date literature profiling. Four features were added to this previously described method: the ability to 1 manually curate keywords extracted from the literature, 2 search genes and gene co-occurrence networks related to custom keywords, 3 compare analyzed gene results with negative and positive controls generated by GenCLiP, and 4 calculate probabilities that the resulting genes and gene networks are randomly related. In this paper, we show with a set of differentially expressed genes between keloids and normal control, how implementation of functions in GenCLiP successfully identified keywords related to the pathogenesis of keloids and unknown gene pathways involved in the pathogenesis of keloids. Conclusion With regard to the identification of disease-susceptibility genes, GenCLiP allows one to quickly acquire a primary pathogenesis profile and identify pathways involving abnormally expressed genes not previously associated with the disease.

    The goal of this pilot study was to determine the effects of short duration, intensive tango lessons on functional mobility in people with Parkinson disease. This study employed a within-subject, prospective, repeated measures design. Fourteen people with idiopathic Parkinson disease participated. All balance and gait assessments were performed in a laboratory, but dance classes took place in a large, open classroom. Participants completed ten 1.5-h long Argentine tango dance lessons within 2 weeks. Their balance, gait and mobility were assessed before and after the training sessions. Measures included the Berg Balance Scale, the Unified Parkinson Disease Rating Scale, gait velocity, functional ambulation profile, step length, stance and single support percent of gait, Timed Up and Go, and the 6 min walk. Participants significantly improved on the Berg Balance Scale (effect size (ES)=0.83, p=0.021), Unified Parkinson Disease Rating Scale Motor Subscale III (ES=-0.64, p=0.029), and percent of time spent in stance during forward walking (ES=0.97, p=0.015). Non-significant improvements were noted on the Timed Up and Go (ES=-0.38, p=0.220) and 6 min walk (ES=0.35, p=0.170). Frequent social dance lessons completed within a short time period appear to be appropriate and effective for these individuals with mild-moderately severe Parkinson disease.

    This study aimed to evaluate the effectiveness of omalizumab among adolescents with moderate-severe allergic asthma inadequately controlled with inhaled corticosteroids. Data from patients 12 to 17 years of age were pooled from 5 placebo-controlled registration trials of omalizumab. Impact on asthma control was assessed by need for rescue bursts of oral corticosteroids, lung function, symptom scores, and unscheduled office visits. In adolescents (n = 146), addition of omalizumab decreased mean number of rescue bursts (0.3 vs 0.9) versus placebo; relative risk 0.47 (95% confidence interval [CI], 0.22-0.99; P = .047). At study conclusion, mean forced expiratory volume in 1 second increased 268 mL (13.8%) in omalizumab-treated subjects versus 98 mL (5.5%) for placebo (least squares mean treatment difference 146 mL [95% CI, 19.4-272.6; P = .024]). Omalizumab significantly improved asthma symptom scores and reduced unscheduled office visits. Omalizumab added to baseline therapy improves measures of asthma control in adolescents with persistent moderate-severe allergic asthma.

  1. Sensibility and Subjectivity: Levinas’ Traumatic Subject

    Full Text Available The importance of Levinas’ notions of sensibility and subjectivity are evident in the revision of phenomenological method by current phenomenologists such as Jean-Luc Marion and Michel Henry. The criticisms of key tenants of classical phenomenology, intentionality and reduction, are of a particular note. However, there are problems with Levinas’ characterization of subjectivity as essentially sensible. In “Totality and Infinity” and “Otherwise than Being”, Levinas criticizes and recasts a traditional notion of subjectivity, particularly the notion of the subject as the first and foremost rational subject. The subject in Levinas’ works is characterized more by its sensibility and affectedness than by its capacity to reason or affect its world. Levinas ties rationality to economy and suggests an alternative notion of reason that leads to his analysis of the ethical relation as the face-to-face encounter. The ‘origin’ of the social relation is located not in our capacity to know but rather in a sensibility that is diametrically opposed to the reason understood as economy. I argue that the opposition in Levinas’ thought between reason and sensibility is problematic and essentially leads to a self-conflicted subject. In fact, it would seem that violence characterizes the subject’s self-relation and, thus, is also inscribed at the base of the social relation. Rather than overcoming a problematic tendency to dualistic thought in philosophy Levinas merely reverses traditional hierarchies of reason/emotion, subject/object and self/other.

To observe the consequences in uncontrolled patients of switching one drug of the combination therapy to candesartan/HCTZ (16 mg/12.5 mg with and without a compliance intervention program. Methods Self-and ambulatory-monitoring of BP were done with upper arm oscillometric devices. Patients' dosing histories were compiled electronically (MEMS(c, AARDEX. Patients with office blood pressure (OBP >140/90 mmHg despite combination therapy were begun on MEMS monitoring and self BP measurement for 4 weeks of run-in. Of 62 such patients, 18 (29% patients were normotensive according to self BP measurement and ambulatory BP measurement at 4 weeks (Group A; in the remaining 44 still uncontrolled patients, candesartan/HCTZ was substituted for one of the combination therapy drugs, with half these patients receiving passive compliance monitoring (B and half a DRC intervention program (C. All groups were then followed for 8 weeks. Results DRC before week 4 was significantly higher in A than in the uncontrolled patients (B&C. DRC was stable during run-in A, but declined in B and C. DRC after week 4 was not different in the three groups and stayed constant over time. DRC during weekends was lower than during weekdays in all groups. In group A no significant change in blood pressure was observed with all three methods of BP measurements.

    Analytical and experimental studies conducted at Semenov Institute of Chemical Physics for investigating the use of pyrotechnic compositions, i.e., thermites, to reduce the risk of the fall of thermally stable parts of deorbiting end-of-life LEO satellites on the Earth are described. The main idea was the use of passive heating during uncontrolled re-entry to ignite thermite composition, fixed on the titanium surface, with the subsequent combustion energy release to be sufficient to perforate the titanium cover. It is supposed, that thus destructed satellite parts will lose their streamline shape, and will burn out being aerodynamically heated during further descending in atmosphere (patent FR2975080). On the base of thermodynamic calculations the most promising thermite compositions have been selected for the experimental phase. The unique test facilities have been developed for the testing of the efficiency of thermite charges to perforate the titanium TA6V cover of 0.8 mm thickness under temperature/pressure conditions duplicated the uncontrolled re-entry of titanium tank after its mission on LEO. Experiments with the programmed laser heating inside the vacuum chamber revealed the only efficient thermite composition among preliminary selected ones to be Al/Co3O4. Experimental searching of the optimal aluminum powder between spherical and flaked nano- and micron-sized ones revealed the possibility to adjust the necessary ignition delay time, according to the titanium cover temperature dependency on deorbiting time. For the titanium tank the maximum temperature is 1100 °C at altitude 68 km and pressure 60 Pa. Under these conditions Al/Co3O4 formulations with nano-Al spherical particles provide the ignition time to be 13.3 s, and ignition temperature as low as 592±5 °C, whereas compositions with the micron-sized spherical Al powder reveal these values to be much higher, i.e., 26.3 s and 869±5 °C, respectively.

    Full Text Available Objective – To compare the search performance (i.e., recall and precision of Google Scholar with that of 11 other bibliographic databases when using a keyword search to find references on later-life migration. Design – Comparative database evaluation. Setting – Not stated in the article. It appears from the author’s affiliation that this research took place in an academic institution of higher learning. Subjects – Twelve databases were compared: Google Scholar, Academic Search Elite, AgeLine, ArticleFirst, EconLit, Geobase, Medline, PAIS International, Popline, Social Sciences Abstracts, Social Sciences Citation Index, and SocIndex. Methods – The relevant literature on later-life migration was pre-identified as a set of 155 journal articles published from 1990 to 2000. The author selected these articles from database searches, citation tracking, journal scans, and consultations with social sciences colleagues. Each database was evaluated with regards to its performance in finding references to these 155 papers.Elderly and migration were the keywords used to conduct the searches in each of the 12 databases, since these were the words that were the most frequently used in the titles of the 155 relevant articles. The search was performed in the most basic search interface of each database that allowed limiting results by the needed publication dates (1990-2000. Search results were sorted by relevance when possible (for 9 out of the 12 databases, and by date when the relevance sorting option was not available. Recall and precision statistics were then calculated from the search results. Recall is the number of relevant results obtained in the database for a search topic, divided by all the potential results which can be obtained on that topic (in this case, 155 references. Precision is the number of relevant results obtained in the database for a search topic, divided by the total number of results that were obtained in the database on

    The adverse health effects and increasing prevalence of obesity in the United States make interventions for obesity a priority in health research. Diet-focused interventions generally do not result in lasting reductions in weight. Behavioral interventions that increase awareness of eating cues and satiety have been postulated to result in healthier eating habits. We hypothesized that participation in a program called mindfulness-based stress reduction (MBSR) would positively influence the eating behaviors and nutritional intake of participants through changes in emotional eating (EE), uncontrolled eating (UE), and type and quantity of food consumed. Forty-eight veterans at a large urban Veterans Administration medical center were assessed before MBSR, after MBSR, and 4 months later. For all participants (N = 48), MBSR participation was not associated with significant changes in EE or UE. In addition, there were no significant differences in the intake of energy, fat, sugar, fruit, or vegetables at either follow-up time point as compared with baseline. Enhanced mindfulness skills and reduced depressive symptoms were seen over time with medium to large effect sizes. Changes in mindfulness skills were significantly and negatively correlated with changes in EE and UE over time. Overall, there was no evidence that participation in MBSR was associated with beneficial changes in eating through reductions in disinhibited eating or significant changes in dietary intake. Randomized studies are needed to further define the relationship between mindfulness program participation and eating behaviors. Published by Elsevier Inc.

    Effective strategies are needed to address the health behaviors of older patients with diabetes. One approach is health coaching, the practice of health education and health promotion through a structured partnership designed to enhance well-being and facilitate the achievement of individuals' health-related goals. The aim of this study was to describe the development of a pilot health coaching curriculum, investigate its effects on geriatric patient outcomes, and examine qualitative feedback by older patients and medical students to the curriculum. This mixed-methods study involved 29 first-year medical students randomly paired with 29 older adults with uncontrolled Type 2 diabetes. Health-related quality of life (HRQoL), stage of change movement, diabetes knowledge, locus of control, Body Mass Index (BMI), and glycosylated hemoglobin (HbA1c) were assessed. Focus groups were used to evaluate patients' and medical students' experiences. Results showed significant increases in patients' HRQoL and stage of change for exercise improved significantly over time. There were no significant changes in stage of change for healthy diet and medication, diabetes knowledge, BMI, and HbA1c from baseline to end of study. Focus group data indicated positive responses by older patients and the medical students. A health coaching curriculum may improve patient outcomes and can provide medical students the skills needed to provide compassionate care for geriatric patients.

    Full Text Available The in-house coupled neutronic and thermal-hydraulic (N/T-H code of BATAN (National Nuclear Energy Agency of Indonesia, NODAL3, based on the few-group neutron diffusion equation in 3-dimensional geometry using the polynomial nodal method, has been verified with static and transient PWR benchmark cases. This paper reports the verification of NODAL3 code in the NEA-NSC PWR uncontrolled control rods withdrawal at zero power benchmark. The objective of this paper is to determine the accuracy of NODAL3 code in solving the continuously slow and fast reactivity insertions due to single and group of control rod bank withdrawn while the power and temperature increment are limited by the Doppler coefficient. The benchmark is chosen since many organizations participated using various methods and approximations, so the calculation results of NODAL3 can be compared to other codes’ results. The calculated parameters are performed for the steady-state, transient core averaged, and transient hot pellet results. The influence of radial and axial nodes number was investigated for all cases. The results of NODAL3 code are in very good agreement with the reference solutions if the radial and axial nodes number is 2 × 2 and 2 × 18 (total axial layers, respectively.

    Several lines of evidence implicate excess glucagon secretion in the elevated rates of hepatic glucose production (HGP), hyperglycemia, and ketosis characteristic of uncontrolled insulin-deficient diabetes (uDM), but whether hyperglucagonemia is required for hyperglycemia in this setting is unknown. To address this question, adult male Wistar rats received either streptozotocin (STZ) to induce uDM (STZ-DM) or vehicle and remained nondiabetic. Four days later, animals received daily subcutaneous injections of either the synthetic GLP-1 receptor agonist liraglutide in a dose-escalating regimen to reverse hyperglucagonemia or its vehicle for 10 days. As expected, plasma glucagon levels were elevated in STZ-DM rats, and although liraglutide treatment lowered glucagon levels to those of nondiabetic controls, it failed to attenuate diabetic hyperglycemia, elevated rates of glucose appearance (Ra), or increased hepatic gluconeogenic gene expression. In contrast, it markedly reduced levels of both plasma ketone bodies and hepatic expression of the rate-limiting enzyme involved in ketone body production. To independently confirm this finding, in a separate study, treatment of STZ-DM rats with a glucagon-neutralizing antibody was sufficient to potently lower plasma ketone bodies but failed to normalize elevated levels of either blood glucose or Ra. These data suggest that in rats with uDM, hyperglucagonemia is required for ketosis but not for increased HGP or hyperglycemia. PMID:25633417

    To evaluate efficacy and safety of a novel technique, simultaneous implantation of Ahmed and Baerveldt shunts, for improved control of intraocular pressure (IOP) in advanced glaucoma with visual field defects threatening central fixation. Retrospective case series; all patients receiving simultaneous Ahmed and Baerveldt implantation at a single institution between October 2004 and October 2009 were included. Records were reviewed preoperatively and at postoperative day 1, week 1, month 1, month 3, month 6, year 1, and yearly until year 5. Outcome measures included IOP, best-corrected visual acuity, visual field mean deviation, cup to disc ratio, number of glaucoma medications, and complications. Fifty-nine eyes were identified; mean (±SD) follow-up was 26±23 months. Primary open-angle glaucoma was most common (n=37, 63%). Forty-six eyes (78%) had prior incisional surgery. Mean preoperative IOP was 25.5±9.8 mm Hg. IOP was reduced 50% day 1 (PIOP is markedly reduced postoperative day 1 following double glaucoma tube implantation with effects persisting over postoperative year 1 and up to year 5. Complications were higher than that seen in reports of single shunt implantation, which may be explained by patient complexity in this cohort. This technique may prove a promising novel approach for management of uncontrolled IOP in advanced glaucoma.

    Acquired hemophilia A (AHA) is a serious and rare complication of pregnancy, caused by autoantibodies to coagulation factor VIII after delivery. We here report the case of a 36-year-old primigravida woman who developed AHA following chorioamnionitis-caused miscarriage in the second trimester. Thirteen days after abortion, sudden, massive vaginal bleeding occurred with marked prolongation of activated partial thromboplastin time (APTT) in the absence of other abnormal coagulation data. Sequential transfusion of fresh frozen plasma did not achieve normalization of APTT. Further examination confirmed reduction of coagulation factor VIII and the presence of its inhibitor, leading to the final diagnosis of AHA. The patient was effectively treated with bypassing agents (activated prothrombin complex concentrate and recombinant activated factor VII) and immunosuppressive therapy. Fifteen months after remission, the patient became pregnant and successfully achieved term delivery with no signs of recurrence. This case illustrates that AHA should be considered in the occurrence of plasma transfusion-uncontrolled severe bleeding after delivery. © 2017 Japan Society of Obstetrics and Gynecology.

    Teleoperated robot-assisted surgery (RAS) is used to perform a wide variety of minimally invasive procedures. However, current understanding of the effect of robotic manipulation on the motor coordination of surgeons is limited. Recent studies in human motor control suggest that we optimize hand movement stability and task performance while minimizing control effort and improving robustness to unpredicted disturbances. To achieve this, the variability of joint angles and muscle activations is structured to reduce task-relevant variability and increase task-irrelevant variability. In this study, we determine whether teleoperation of a da Vinci Si surgical system in a nonclinical task of simple planar movements changes this structure of variability in experienced surgeons and novices. To answer this question, we employ the UnControlled manifold analysis that partitions users' joint angle variability into task-irrelevant and task-relevant manifolds. We show that experienced surgeons coordinate their joint angles to stabilize hand movements more than novices, and that the effect of teleoperation depends on experience--experts increase teleoperated stabilization relative to freehand whereas novices decrease it. We suggest that examining users' exploitation of the task-irrelevant manifold for stabilization of hand movements may be applied to: (1) evaluation and optimization of teleoperator design and control parameters, and (2) skill assessment and optimization of training in RAS.

    Full Text Available The cowpea is a Fabaceae originated in Africa cultivated in the northern and northeastern of Brazil, where stands out as the main source of protein for the population. For the establishment of culture, seeds are treated to control and prevent pest attacks and diseases, can also attach nutrients to the seeds which will be available for plant development. The objective of the research was to evaluate the performance of cowpea seeds treated with chemical products and stored in controlled and uncontrolled temperature and humidity conditions. The following seeds treatments were applied: control (no treatment; micronutrient Comol 118, insecticide thiamethoxam, fipronil and pyraclostrobin+thiophanate-methyl and imidacloprid+thiodicarb were then stored in a cold environment and natural. The assessment of physiological seed quality was made initially and every 45 days through the germination and vigor. Among all products used, the imidacloprid + thiodicarb and fipronil + pyraclostrobin + thiophanate methyl provides stimulating effect on seed performance; seeds treated with thiamethoxam were less affected by storage than the untreated seeds; seeds treated with micronutrients exhibits similar behavior to untreated seeds and storage in a controlled environment better preserves the seed physiological quality.

    A high prevalence of uncontrolled hypertension among Blacks is a major cause of racial health disparities in the United States. We established a community/academic partnership to improve hypertension control in Blacks receiving medical care at a federally qualified health center in Milwaukee. The defining components of our program included: six group sessions (one/month), based on the American Heart Association's Simple Seven curriculum and designed to motivate and empower patients to manage their blood pressure; active involvement of a community health worker; and ongoing participation of a community advisory board. The study design included a matched control group not exposed to the intervention. Patients in both groups received their usual medical care. Overall, compared to baseline, systolic blood pressure decreased at both 6 and 12 months (P < 0.004); however, the reduction of blood pressure in the intervention and control groups did not differ significantly (P = .62). Based on written responses to a questionnaire and structured focus group interviews after completing the six-month program, participants reported that the intervention was effective. In retrospect, they suggested that more attention might have been given to spirituality and stress reduction. Larger and longer-term studies will be required to evaluate the added value of this type of intervention.

    To predict the stability of pharmaceutical preparations under uncontrolled temperature conditions accurately, a method to compute the average reaction rate constant taking into account the heat transfer from the atmosphere to the product was developed. The average reaction rate constants computed with taken into consideration heat transfer (κ(re) ) were then compared with those computed without taking heat transfer into consideration (κ(in) ). The apparent thermal diffusivity (κ(a) ) exerted some influence on the average reaction rate constant ratio (R, R = κ(re) /κ(in) ). In the regions where the κ(a) was large (above 1 h(-1) ) or very small, the value of R was close to 1. On the contrary, in the middle region (0.001-1 h(-1) ), the value of R was less than 1.The κ(a) of the central part of a large-size container and that of the central part of a paper case of 10 bottles of liquid medicine (100 mL) fell within this middle region. On the basis of the above-mentioned considerations, heat transfer may need to be taken into consideration to enable a more accurate prediction of the stability of actual pharmaceutical preparations under nonisothermal atmospheres.

    Bulimia nervosa (BN) has been associated with dysregulation of the central catecholaminergic system. An instructive way to investigate the relationship between catecholaminergic function and psychiatric disorder has involved behavioral responses to experimental catecholamine depletion (CD). The purpose of this study was to examine a possible catecholaminergic dysfunction in the pathogenesis of bulimia nervosa. CD was achieved by oral administration of alpha-methyl-para-tyrosine (AMPT) in 18 remitted female subjects with BN (rBN) and 31 healthy female control subjects. The study design consisted of a randomized, double blind, placebo-controlled crossover, single-site experimental trial. The main outcome measures were bulimic symptoms assessed by the Eating Disorder Examination-Questionnaire. Measures were assessed before and 26, 30, 54, 78, 102 hours after the first AMPT or placebo administration. In the experimental environment (controlled environment with a low level of food cues) rBN subjects had a greater increase in eating disorder symptoms during CD compared with healthy control subjects (condition × diagnosis interaction, p < .05). In the experimental environment, rBN subjects experienced fewer bulimic symptoms than in the natural environment (uncontrolled environment concerning food cues) 36 hours after the first AMPT intake (environment × diagnosis interaction, p < .05). Serum prolactin levels increased significantly, and to a comparable degree across groups, after AMPT administration. This study suggests that rBN is associated with vulnerability for developing eating disorder symptoms in response to reduced catecholamine neurotransmission after CD. The findings support the notion of catecholaminergic dysfunction as a possible trait abnormality in BN. © 2014 Society of Biological Psychiatry Published by Society of Biological Psychiatry All rights reserved.

    Multiple access technique is one of important techniques within medium access layer in TCP/IP protocol stack. Each network technology implements the selected access method. Priority can be implemented in those methods to differentiate services. Some internet networks are dedicated for specific purpose. Education browsing or tutorial video accesses are preferred in a library hotspot, while entertainment and sport contents could be subjects of limitation. Current solution may use IP address filter or access list. This paper proposes subjective properties of users or applications are used for priority determination in multiple access techniques. The NS-2 simulator is employed to evaluate the method. A video surveillance network using WiMAX is chosen as the object. Subjective priority is implemented on WiMAX scheduler based on traffic properties. Three different traffic sources from monitoring video: palace, park, and market are evaluated. The proposed subjective scheduler prioritizes palace monitoring video that results better quality, xx dB than the later monitoring spots.

    It is recommended that patients initiate triple antiemetic therapy with one of the 5-hydroxytryptamine receptor antagonists (5-HT(3) RAs), aprepitant (or its intravenous prodrug fosaprepitant) and dexamethasone prior to the start of highly emetogenic chemotherapy (HEC). However, the impact of 5-HT(3) RA selection within triple antiemetic regimens on the risk of uncontrolled chemotherapy-induced nausea and vomiting (CINV) with HEC has not been well studied. To assess the likelihood of an uncontrolled CINV event following antiemetic prophylaxis with the 5-HT(3) RA palonosetron + aprepitant/fosaprepitant + dexamethasone (palonosetron cohort) versus any of the other 5-HT(3) RAs + aprepitant/fosaprepitant + dexamethasone (other 5-HT(3) RA cohort) among single-day HEC cycles. Single-day HEC cycles (a gap of at least 5 days between two administrations) among patients with a cancer diagnosis and receiving antiemetic prophylaxis with the aforementioned regimens between 1/1/2006 and 6/30/2010 were identified from the IMS LifeLink claims database. Uncontrolled CINV events were identified through ICD-9-CM codes (nausea and vomiting), Current Procedural Terminology codes (hydration), rescue medications and/or use of antiemetic therapy from days 2-5 following HEC administration. Risks for an uncontrolled CINV event among all patients, and within breast cancer and multiple cancer subpopulations, were analyzed at cycle level using logistic multivariate regression models. A total of 8018 cycles for the palonosetron cohort and 1926 cycles for the other 5-HT(3) RA cohort (3574 and 978 patients, respectively) were analyzed. Single-day HEC cycles received by the palonosetron cohort had a significantly lower unadjusted risk of an uncontrolled CINV event (17.5 vs 20.7% for the other 5-HT(3) RA cohort; p = 0.0010), with a 17% lower adjusted risk for palonosetron-administered cycles (odds ratio: 0.83; 95% CI: 0.73-0.94; p = 0.0042).

    Radioactive lightning rods were manufactured in Brazil until 1989, when the licenses for using radioactive sources in these products were lifted by the national nuclear authority. Since then, these rods have been replaced by the Franklin type and collected as radioactive waste. However, only 20% of the estimated total number of installed rods has been delivered to the Brazilian Nuclear Commission. This situation causes concern, since there is the possibility of the rods to be disposed as domestic waste. In Brazil, 64% of the municipal solid waste is disposed at garbage dumps without sufficient control. In addition, (241)Am, the radionuclide most commonly employed, is classified as a high-toxicity element, when incorporated. In the present study, (241)Am migration experiments were performed by means of a lysimeter system, in order to evaluate the risk of contamination caused by radioactive lightning rods disposed as common solid waste. (241)Am sources removed from lightning rods were placed inside lysimeters filled with organic waste that was collected at the restaurant of the Instituto de Pesquisas Energéticas e Nucleares. The generated leachate was periodically analyzed, and characteristics such as pH, redox potential, solid content and the concentration of the radioactive material were determined. The equivalent dose for members of the public was calculated considering ingestion of contaminated drinking water as the major path of exposure. Estimated doses were about 20-times below the effective dose limit of 1 mSv year(-1) for members of the public as recommended by the International Commission on Radiological Protection. This suggests the radiation risk caused by lightning rods disposed at uncontrolled garbage dumps to be low. It should be noted, however, that the number of investigated lightning rods was quite small. The results of this study might therefore not be entirely representative and should be interpreted with care. They provide, however, a very first

    We sought to compare the risk of end stage renal disease (ESRD), ischemic heart event (IHE), congestive heart failure (CHF), cerebrovascular accident (CVA), and all-cause mortality among 470,386 individuals with resistant and nonresistant hypertension (non-RH). Resistant hypertension (60,327 individuals) was sub-categorized into 2 groups; 23,104 patients with cRH (controlled on 4 or more medicines) and 37,223 patients with uRH (uncontrolled on 3 or more medicines) in a 5 year retrospective cohort study. Cox proportional hazard modeling was used to estimate hazard ratios adjusting for age, gender, race, body mass index, chronic kidney disease (CKD), and co-morbidities. Resistant hypertension (cRH and uRH) compared to non-RH, had multivariable adjusted hazard ratios (95% confidence intervals) of 1.32 (1.27–1.37), 1.24 (1.20–1.28), 1.46 (1.40–1.52), 1.14 (1.10–1.19), and 1.06 (1.03–1.08) for ESRD, IHE, CHF, CVA, and mortality, respectively. Comparison of uRH to cRH had hazard ratios of 1.25 (1.18–1.33), 1.04 (0.99–1.10), 0.94 (0.89–1.01), 1.23 (1.14–1.31), and 1.01 (0.97–1.05) for ESRD, IHE, CHF, CVA, and mortality, respectively. Males and Hispanics had greater risk for ESRD within all 3 cohorts. Resistant hypertension had greater risk for ESRD, IHE, CHF, CVA, and mortality. The risk of ESRD and CVA and were 25% and 23% greater, respectively, in uRH compared to cRH supporting the linkage between blood pressure and both outcomes. PMID:25945406

    BACKGROUND AND PURPOSE IL-13 is a pleiotropic Th2 cytokine considered likely to play a pivotal role in asthma. Here we describe the preclinical in vitro and in vivo characterization of CAT-354, an IL-13-neutralizing IgG4 monoclonal antibody (mAb), currently in clinical development. EXPERIMENTAL APPROACH In vitro the potency, specificity and species selectivity of CAT-354 was assayed in TF-1 cells, human umbilical vein endothelial cells and HDLM-2 cells. The ability of CAT-354 to modulate disease-relevant mechanisms was tested in human cells measuring bronchial smooth muscle calcium flux induced by histamine, eotaxin generation by normal lung fibroblasts, CD23 upregulation in peripheral blood mononuclear cells and IgE production by B cells. In vivo CAT-354 was tested on human IL-13-induced air pouch inflammation in mice, ovalbumin-sensitization and challenge in IL-13 humanized mice and antigen challenge in cynomolgus monkeys. KEY RESULTS CAT-354 has a 165 pM affinity for human IL-13 and functionally neutralized human, human variant associated with asthma and atopy (R130Q) and cynomolgus monkey, but not mouse, IL-13. CAT-354 did not neutralize human IL-4. In vitro CAT-354 functionally inhibited IL-13-induced eotaxin production, an analogue of smooth muscle airways hyperresponsiveness, CD23 upregulation and IgE production. In vivo in humanized mouse and cynomolgus monkey antigen challenge models CAT-354 inhibited airways hyperresponsiveness and bronchoalveolar lavage eosinophilia. CONCLUSIONS AND IMPLICATIONS CAT-354 is a potent and selective IL-13-neutralizing IgG4 mAb. The preclinical data presented here support the trialling of this mAb in patients with moderate to severe uncontrolled asthma. PMID:21895629

    Assess the safety of adjunctive lacosamide for the treatment of uncontrolled primary generalized tonic-clonic seizures in patients (16-65 years) with primary generalized (genetic) epilepsy (PGE). An open-label pilot safety study (SP0961; NCT01118949), comprising 12 weeks' historical baseline, 4 weeks' prospective baseline, 3 weeks' titration (target: 400mg/day adjunctive lacosamide) and 6 weeks' maintenance. Patients who continued to the extension study (SP0962; NCT01118962) then received ≤59 weeks of flexible treatment (100-800mg/day lacosamide with flexible dosing of concomitant antiepileptic drugs). The primary outcomes for SP0961 were the mean change (±standard deviation) in absence seizure or myoclonic seizure days per 28days from prospective baseline to maintenance; for SP0962, the incidence of treatment-emergent adverse events (TEAEs) and withdrawals because of TEAEs. Of the 49 patients who enrolled, 40 (82%) completed the pilot study and 9 discontinued (5 because of adverse events). Of the 39 patients who continued to the extension study, 10 discontinued (2 owing to TEAEs) and 29 (74%) completed the study. During the pilot study, patients reported a reduction in mean (±standard deviation) absence and myoclonic seizure days per 28days (-0.37±4.80, -2.19±5.80). Reductions were also observed during the extension study (-2.38±5.54, -2.78±6.43). Five patients in SP0961 and 2 patients in SP0962 experienced TEAEs of new or increased frequency of absence seizures or myoclonic seizures. The most common TEAEs during SP0961 were dizziness (39%) and nausea (27%), and during SP0962 were dizziness (26%) and upper respiratory tract infection (26%). The safety profile of adjunctive lacosamide was similar to that previously published. Adjunctive lacosamide did not systematically worsen absence or myoclonic seizures, and appears to be well tolerated in patients with PGE. Copyright © 2016. Published by Elsevier B.V.

    Several lines of evidence implicate excess glucagon secretion in the elevated rates of hepatic glucose production (HGP), hyperglycemia, and ketosis characteristic of uncontrolled insulin-deficient diabetes (uDM), but whether hyperglucagonemia is required for hyperglycemia in this setting is unknown. To address this question, adult male Wistar rats received either streptozotocin (STZ) to induce uDM (STZ-DM) or vehicle and remained nondiabetic. Four days later, animals received daily subcutaneous injections of either the synthetic GLP-1 receptor agonist liraglutide in a dose-escalating regimen to reverse hyperglucagonemia or its vehicle for 10 days. As expected, plasma glucagon levels were elevated in STZ-DM rats, and although liraglutide treatment lowered glucagon levels to those of nondiabetic controls, it failed to attenuate diabetic hyperglycemia, elevated rates of glucose appearance (Ra), or increased hepatic gluconeogenic gene expression. In contrast, it markedly reduced levels of both plasma ketone bodies and hepatic expression of the rate-limiting enzyme involved in ketone body production. To independently confirm this finding, in a separate study, treatment of STZ-DM rats with a glucagon-neutralizing antibody was sufficient to potently lower plasma ketone bodies but failed to normalize elevated levels of either blood glucose or Ra. These data suggest that in rats with uDM, hyperglucagonemia is required for ketosis but not for increased HGP or hyperglycemia. © 2015 by the American Diabetes Association.

    Full Text Available Abstract Background Although trazodone is frequently used by fibromyalgia patients, its efficacy on this disease has not been adequately studied. If effective, pregabalin, whose beneficial effects on pain and sleep quality in fibromyalgia have been demonstrated, could complement the antidepressant and anxiolytic effects of trazodone. The aim of the present study was to assess the effectiveness of trazodone alone and in combination with pregabalin in the treatment of fibromyalgia. Methods This was an open-label uncontrolled study. Trazodone, flexibly dosed (50-300 mg/day, was administered to 66 fibromyalgia patients during 12 weeks; 41 patients who completed the treatment accepted to receive pregabalin, also flexibly dosed (75-450 mg/day, added to trazodone treatment for an additional 12-week period. Outcome measures included the Fibromyalgia Impact Questionnaire (FIQ, the Pittsburgh Sleep Quality Index (PSQI, the Beck Depression Inventory (BDI, the Hospital Anxiety and Depression Scale (HADS, the Brief Pain Inventory (BPI, the Short-Form Health Survey (SF-36, and the Patients' Global Improvement scale (PGI. Emergent adverse reactions were recorded. Data were analyzed with repeated measures one-way ANOVA and paired Student's t test. Results Treatment with trazodone significantly improved global fibromyalgia severity, sleep quality, and depression, as well as pain interference with daily activities although without showing a direct effect on bodily pain. After pregabalin combination additional and significant improvements were seen on fibromyalgia severity, depression and pain interference with daily activities, and a decrease in bodily pain was also apparent. During the second phase of the study, only two patients dropped out due to side effects. Conclusions Trazodone significantly improved fibromyalgia severity and associated symptomatology.

    Full Text Available Background: Omalizumab is the first and yet the only biopreparation for asthma which combines high efficiency and high cost. The clinical-economic expediency of using omalizumab in asthmatic children has not been previously studied in Russia.Objective: Our aim was to evaluate the clinical and economic expediency of using omalizumab as additive treatment (to basic or supporting therapy in children with severe uncontrolled atopic asthma under the Russian economic conditions.Methods: We conducted a mathematical simulation of asthma treatment in children with an increased frequency of hospitalization (9 times per year with an average monthly omalizumab requirement of 558 mg. The model is based on the Markov chain. The model includes direct and non-direct costs. The planning horizons were 2 and 5 years. We analyzed the efficiency and utility of the costs and their influence on the budget. The stability of received data is proven by sensitivity analyzis.Results: Over a 5-year planning horizon the cost of an additional year of quality life (due to using omalizumab was 1,259,185 roubles, while the “society’s solvency” is 1 341 308 roubles (cost utility analizis. It takes 39,820 rubles to prevent one hospitalization with omalizumab over a 5-year planning horizon (cost efficiency analizis, which is comparable to the cost of hospitalization (43,141 rubles. Total costs for treating 100 children with asthma, 7 of which would be treated with omalizumab, were equal to the amount of money which is enough to treat 105 children without omalizumab (analysis of budgetary influence.Conclusion: The analyses of cost efficiency and utility have shown that the strategy of using omalizumab together with standard treatment is economically expedient. Budgetary influence analysis has not detected a significant burden on the budget.

    Refusal to consent to organ donation is an important cause of the persisting gap between the number of potential organ donors and effectuated donors. In the Netherlands, organ donors include both uncontrolled donors: donors who die unexpectedly after cardiac death (DCD), after failed resuscitation and donors in whom death can be expected and donors after brain death, and controlled DCD donors: those who die after the withdrawal of treatment. Different donor type implies a different setting in which relatives are requested to consent to organ donation. It is unknown whether the setting influences the eventual decision for donation or not. Therefore, we compared the consent rate in potential donors who died unexpectedly (UD group) and in whom death was expected. A total of 523 potential organ donors between 2003 and 2011 in the 715-bed Maastricht University Medical Centre, the Netherlands were included. Both the patients' registration in the national donor register (DR) and the relatives' refusal rate in the two groups were retrospectively assessed using data from the donation application database. There were 109 unexpected and 414 expected potential donors The potential donors in the UD group were younger (mean age 52 versus 55 years, P = 0.032) and more often male (68 versus 52%, P = 0.003). There were no significant differences in registration in the DR between the groups. The relatives' consent rate in non-registered potential donors, or those who mandated the relatives for that decision, was higher in the UD group (53 versus 29%, P organ donation. The relatives of potential donors who died unexpectedly consented more often to donation than those in whom death was expected.

    Health knowledge and literacy are among the main determinants of health. Assessment of these issues via Web-based surveys is growing continuously. Research has suggested that approximately one-fifth of respondents submit cribbed answers, or cheat, on factual knowledge items, which may lead to measurement error. However, little is known about methods of discouraging cheating in Web-based surveys on health knowledge. This study aimed at exploring the usefulness of imposing a survey time limit to prevent help-seeking and cheating. On the basis of sample size estimation, 94 undergraduate students were randomly assigned in a 1:1 ratio to complete a Web-based survey on nutrition knowledge, with or without a time limit of 15 minutes (30 seconds per item); the topic of nutrition was chosen because of its particular relevance to public health. The questionnaire consisted of two parts. The first was the validated consumer-oriented nutrition knowledge scale (CoNKS) consisting of 20 true/false items; the second was an ad hoc questionnaire (AHQ) containing 10 questions that would be very difficult for people without health care qualifications to answer correctly. It therefore aimed at measuring cribbing and not nutrition knowledge. AHQ items were somewhat encyclopedic and amenable to Web searching, while CoNKS items had more complex wording, so that simple copying/pasting of a question in a search string would not produce an immediate correct answer. A total of 72 of the 94 subjects started the survey. Dropout rates were similar in both groups (11%, 4/35 and 14%, 5/37 in the untimed and timed groups, respectively). Most participants completed the survey from portable devices, such as mobile phones and tablets. To complete the survey, participants in the untimed group took a median 2.3 minutes longer than those in the timed group; the effect size was small (Cohen's r=.29). Subjects in the untimed group scored significantly higher on CoNKS (mean difference of 1.2 points, P=.008

    Pharmaceutical care programs may be an option to improve blood pressure (BP) control in patients with uncontrolled hypertension. The aim of this study was to evaluate the efficacy of pharmaceutical care programs in treating patients with resistant hypertension. In a double-blind randomized clinical trial, 71 patients with uncontrolled BP were enrolled in a pharmaceutical care program or in a control group and underwent a series of cognitive tests. The primary outcome was change in ambulatory BP (ABP) between the baseline evaluation and the final visit 6 months later. The secondary outcomes were the frequency of drug-related problems and adherence as determined by plasma levels of hydrochlorothiazide. The delta-values between the intervention and control groups for ABP in the different daily periods, with the corresponding 95% confidence limits, adjusted for age and baseline BP were: 3 (-1 to 5), 2 (-2 to 4), and 5 (-1 to 6) mm Hg for 24 h, daily and nightly systolic BP, respectively. The corresponding values for diastolic BP were 1 (-1 to 3), 0 (-2 to 2), and 3 (-1 to 4) mm Hg, respectively. Hydrochlorothiazide was detected in the plasma in 21 of 27 patients in the intervention group that attended to all appointments and 24 of 30 patients in the control group (P = .904). The pharmaceutical care program tested in this trial was feasible and showed a trend for better BP control in patients with uncontrolled hypertension.

    Abstract Although blockade of the renin-angiotensin system by increasing the dose of angiotensin II receptor blockers (ARBs) is recommended to achieve clinical benefits in terms of blood pressure (BP) control and cardiovascular and renal outcomes, the effect of this increased dose on ambulatory BP monitoring has not been evaluated completely in Japanese patients with uncontrolled hypertension undergoing medium-dose ARB therapy. The primary objective of this study was to examine the effect of the relatively high dose of the ARB candesartan (12 mg/day) on 24-h systolic BP and the attainment of target BP levels in uncontrolled hypertension treated with a medium dose of ARBs. A total of 146 hypertensive patients (age: 69.9 ± 9.3 years; females: 65.8%) completed the study. After switching to candesartan at 12 mg/day, all these BP measurements decreased significantly (pdiuretics than those without (p=0.0206). Multivariate analysis revealed a significant correlation between the combined ARB and diuretic therapy, and the change in 24-h systolic BP irrespective of preceding ARBs. In conclusion, the switching therapy to increased dose of candesartan caused significant reductions in office and ambulatory BP levels, and improved the attainment of target BP levels in patients with uncontrolled hypertension treated with a medium dose of ARBs. Combination with diuretics enhanced this effect.

    Symbolic sequences have been extensively investigated in the past few years within the framework of statistical physics. Paradigmatic examples of such sequences are written texts, and deoxyribonucleic acid (DNA) and protein sequences. In these examples, the spatial distribution of a given symbol (a word, a DNA motif, an amino acid) is a key property usually related to the symbol importance in the sequence: The more uneven and far from random the symbol distribution, the higher the relevance of the symbol to the sequence. Thus, many techniques of analysis measure in some way the deviation of the symbol spatial distribution with respect to the random expectation. The problem is then to know the spatial distribution corresponding to randomness, which is typically considered to be either the geometric or the exponential distribution. However, these distributions are only valid for very large symbolic sequences and for many occurrences of the analyzed symbol. Here, we obtain analytically the exact, randomly expected spatial distribution valid for any sequence length and any symbol frequency, and we study its main properties. The knowledge of the distribution allows us to define a measure able to properly quantify the deviation from randomness of the symbol distribution, especially for short sequences and low symbol frequency. We apply the measure to the problem of keyword detection in written texts and to study amino acid clustering in protein sequences. In texts, we show how the results improve with respect to previous methods when short texts are analyzed. In proteins, which are typically short, we show how the measure quantifies unambiguously the amino acid clustering and characterize its spatial distribution.

    Full Text Available The contribution of modern science to the progress of civilization is immeasurable. Even its tendency toward exclusive concentration on the objective world has had salutary effects of great value. Modern science has wiped away much that was merely superstitious or speculative. Its rejection of unfounded opinions and prejudices has helped the thinking mind question conventional beliefs, shed preferences and prejudices, and challenge established authority. But modern systems thinking inherited from natural science is the suppression of the subjective dimension of reality. Many complex systems are an attempt to define and represent all subjective experience in physical terms. The modern man has a bias towards objectivity. The powerful influence of sense impressions on his mind and thinking makes him ignore the subjective experience and consider only objective facts as a valid, legitimate and representation of reality. Observing objective factors that are physical is easier than observing subjective factors that are subtle. The mechanistic view of reality has led to the rejection of the role of the individual in social development as insignificant. The individuals determine the development of society. Their social power has its roots both in subjective factors and objective factors. Economy, politics, society, and culture are inseparable dimensions of a single integrated reality. Subject and object constitute an integrated whole. The mind sees them as separate and independent. Or it views one as completely subordinate to the other. Unbiased approach to the study of all human experiences may prove that subject and object are interdependent dimensions or elements of reality.

    Full Text Available Abstract Every product of design must evoke appropriate sensorial and symbolic resonances in the subjects to which it is offered, not simply by satisfying to their specific .rational. needs but mainly by appealing to their 'irrational' desires. Thus, a successful product is one that evokes a polymorphous, complex 'image' of itself in people's minds, onto which targeted subjects may project their respective desires. According to Lacan.s theories, therefore, any successful product is one that becomes a mediating sign between the conscious subject and his unconcious 'object' of desire, which means that products are consumed not merely for their 'objective' properties, as commodities, but as brands imbued with specific images and fantasies. Keywords: signification; desire; design Resumo Significação, comunicação e o sujeito do desejo - Todo produto de design precisa despertar ressonâncias sensoriais e simbólicas apropriadas nos sujeitos aos quais se oferece. Não simplesmente apelando para necessidades racionais específicas de seus consumidores em potencial, mas principalmente se dirigindo aos seus desejos. Por isso, qualquer produto de sucesso, de acordo com as teorias de Lacan, é aquele que se torna um signo mediador entre o sujeito consciente e seu inconsciente 'objeto' de desejo, o que significa que produtos não são simplesmente consumidos por suas propriedades 'objetivas', como mercadorias, mas como marcas, com imagens e fantasias específicas.

    Full Text Available Abstract Diabetes mellitus (DM may adversely affect periodontal tissues during orthodontic tooth movement (OTM. The aim of this review is to systematically analyze and review animal studies investigating the effect of DM on periodontal tissues during OTM. An electronic search was conducted via PubMed/Medline, Google Scholar, Embase, ISI Web of Knowledge, and Cochrane Central Register of Controlled Trials (CONTROL using the keywords “diabetes,” “orthodontics,” and “tooth movement” for studies published between January 2000 and August 2016. After elimination of duplicate items, the primary search resulted in 89 articles. After exclusion of irrelevant articles on the basis of abstract and title, full texts of 25 articles were read to exclude additional irrelevant studies. Seven animal studies were included in this review for qualitative analysis. When compared to healthy animals, more bone resorption and diminished bone remodeling were observed in diabetic animals in all studies. Furthermore, DM decreased the rate of OTM in one study, but in another study, DM accelerated OTM. DM may adversely affect bone remodeling and tooth movement during application of orthodontic forces. However, a number of potential sources of bias and deficiencies in methodology are present in studies investigating the association between OTM and DM. Hence, more long-term and well-designed studies are required before the exact mechanism and impact of DM on outcomes of orthodontic treatment is understood.

    Full Text Available Abstract Background Little is known about the association between cigarette smoking and asthma severity. We assessed smoking as a determinant of disease severity and control in a cohort of clinic-referred allergic subjects who developed new onset asthma. Methods Allergic rhinitis subjects with no asthma (n = 371 were followed-up for 10 years and routinely examined for asthma diagnosis. In those who developed asthma (n = 152, clinical severity and levels of asthma control were determined. Among these subjects, 74 (48.7% were current smokers, 17 (11.2% former smokers, and 61 (40.1% never smokers. Results When comparing current or past smokers to never smokers they had a higher risk of severe asthma in the univariate analysis, which became non-significant in the multivariate analysis. On the other hand, the categories of pack-years were significantly related to severe asthma in a dose response relationship in both the univariate and multivariate analysis: compared to 0 pack years, those who smoked 1-10 pack-years had an OR(95% CI of 1.47(0.46-4.68, those who smoked 11-20 pack-years had an OR of 2.85(1.09-7.46 and those who smoked more than 20 pack-years had an OR of 5.59(1.44-21.67 to develop more severe asthma. Smokers with asthma were also more likely to have uncontrolled disease. A significant dose-response relationship was observed for pack-years and uncontrolled asthma. Compared to 0 pack years, those who smoked 1-10 pack-years had an OR of 5.51(1.73-17.54 and those who smoked more than 10 pack-years had an OR of 13.38(4.57-39.19 to have uncontrolled asthma. Conclusions The current findings support the hypothesis that cigarette smoking is an important predictor of asthma severity and poor asthma control.

    Fruit and vegetable prescription programs have been shown to increase consumption of fresh produce, but whether they have an impact on medical outcomes is unknown. The purpose of this study was to examine the role of participation in a farmers' market and fruit and vegetable prescription program on changes in hemoglobin A1C (HbA1C), blood pressure (BP) and weight in patients with uncontrolled type 2 diabetes at a federally qualified health center (FQHC) in Detroit, MI. The 13-week Fresh Prescription program (June 2015-October 2015) was designed to improve access and consumption of produce among low-income patients with uncontrolled type 2 diabetes. The program allotted up to $40 ($10 per week for up to four weeks) for purchase of produce from a FQHC located farmers' market. Adult, non-pregnant patients with a history of type 2 diabetes that had an elevated HbA1C > 6.5 within three months before Fresh Prescription program were eligible to participate. HgA1c, BP and weight were collected within three months of program start and within three months of completion. There were 65 eligible participants with complete biometric data. A statistically significant (p = 0.001) decrease in HbA1C was found (9.54% to 8.83%). However, weight (208.3 lbs. to 209.0 lbs.) and BP (135.1/79.3 mm Hg to 135.8/77.6 mm Hg) did not change from pre- to post-study (p > 0.05). Access to a fruit and vegetable prescription program over a 13-week period led to decreased HbA1C concentrations in uncontrolled type 2 diabetic patients living in an urban area of predominately-lower socioeconomic status.

  13. Investigation of the adsorption mechanism of a peptide in reversed phase liquid chromatography, from pH controlled and uncontrolled solutions

    The single-component equilibrium adsorption of the tripeptide Leucyl-Leucyl-Leucine (LLL) on a high-efficiency Jupiter Proteo column (C{sub 12}) was investigated experimentally and modeled theoretically. The experimental equilibrium isotherms of LLL for adsorption on a C{sub 12} packing material from an aqueous solution of methanol (48%) and trifluoroacetic acid (0.1%) were measured by frontal analysis (FA). The FA measurements were done with two solutions, one in which the pH was controlled, the other in which it was not. Two solutions of LLL in the mobile phase were prepared (4.3 and 5.4 g/L) and their pH measured (2.94 and 2.88), respectively. The first solution was titrated with TFA to match the pH of the mobile phase (2.03), so its pH was controlled. The pH of the other solution was left uncontrolled. In both cases the isotherms could be modeled by a bi-Langmuir equation, a choice consistent with the bimodal affinity energy distribution (AED) obtained for LLL. The isotherm parameters derived from the inverse method (IM) of isotherm determination under controlled pH conditions (by fitting calculated profiles to experimental breakthrough profiles) are in a good agreement with those derived from the FA data. Under uncontrolled pH conditions, the application of IM suggests the coexistence of two different adsorption mechanisms. According to the isotherm parameters found by these three methods (FA, AED and IM), the C{sub 12}-bonded silica can adsorb around 500 and 70 g/L of LLL under controlled and uncontrolled pH conditions, respectively. The adsorption of LLL on the C{sub 12} material strongly depends on the pH of the mobile phase and on the quantity of TFA added, which plays the role of an ion-pairing agent.

  14. Science of the subjective.

    Jahn, R G; Dunne, B J

    2007-01-01

    Over the greater portion of its long scholarly history, the particular form of human observation, reasoning, and technical deployment we properly term "science" has relied at least as much on subjective experience and inspiration as it has on objective experiments and theories. Only over the past few centuries has subjectivity been progressively excluded from the practice of science, leaving an essentially secular analytical paradigm. Quite recently, however, a compounding constellation of newly inexplicable physical evidence, coupled with a growing scholarly interest in the nature and capability of human consciousness, are beginning to suggest that this sterilization of science may have been excessive and could ultimately limit its epistemological reach and cultural relevance. In particular, an array of demonstrable consciousness-related anomalous physical phenomena, a persistent pattern of biological and medical anomalies, systematic studies of mind/brain relationships and the mechanics of human creativity, and a burgeoning catalogue of human factors effects within contemporary information processing technologies, all display empirical correlations with subjective aspects that greatly complicate, and in many cases preclude, their comprehension on strictly objective grounds. However, any disciplined re-admission of subjective elements into rigorous scientific methodology will hinge on the precision with which they can be defined, measured, and represented, and on the resilience of established scientific techniques to their inclusion. For example, any neo-subjective science, while retaining the logical rigor, empirical/theoretical dialogue, and cultural purpose of its rigidly objective predecessor, would have the following requirements: acknowledgment of a proactive role for human consciousness; more explicit and profound use of interdisciplinary metaphors; more generous interpretations of measurability, replicability, and resonance; a reduction of ontological

    Organ donation after cessation of circulation and respiration, both controlled and uncontrolled, has been proposed by the Institute of Medicine as a way to increase opportunities for organ procurement. Despite claims to the contrary, both forms of controlled and uncontrolled donation after cardiac death raise significant ethical and legal issues. Identified causes for concern include absence of agreement on criteria for the declaration of death, nonexistence of universal guidelines for duration before stopping resuscitation efforts and techniques, and assumption of presumed intent to donate for the purpose of initiating temporary organ-preservation interventions when no expressed consent to donate is present. From a legal point of view, not having scientifically valid criteria of cessation of circulation and respiration for declaring death could lead to a conclusion that organ procurement itself is the proximate cause of death. Although the revised Uniform Anatomical Gift Act of 2006 provides broad immunity to those involved in organ-procurement activities, courts have yet to provide an opinion on whether persons can be held liable for injuries arising from the determination of death itself. Preserving organs in uncontrolled donation after cardiac death requires the administration of life-support systems such as extracorporeal membrane oxygenation. These life-support systems can lead to return of signs of life that, in turn, have to be deliberately suppressed by the administration of pharmacological agents. Finally, allowing temporary organ-preservation interventions without expressed consent is inherently a violation of the principle of respect for a person's autonomy. Proponents of organ donation from uncontrolled donation after cardiac death, on the other hand, claim that these nonconsensual interventions enhance respect for autonomy by allowing people, through surrogate decision making, to execute their right to donate organs.

RESULTS Two hundred sixty-one jurors (74.6%) believed that a $500 payment would impair subjects' ability to think carefully about the risks and benefits of research. Ninety-six of 120 (80%) expressed this concern about subjects with a low income ($50,000). In contrast, only 69 (19.7%) of jurors believed that a $500 payment would influence them. Jurors who believed that this payment would influence them reported lower incomes and less education. CONCLUSION Members of the general public share ethical concerns about the influence of payments for research, although they believe that these concerns are more applicable to others than to themselves.

    Given the extent, magnitude and functional significance of the neurocognitive deficits of schizophrenia, growing attention has been paid recently to patients' self-awareness of their own deficits. Thus far, the literature has shown either that patients fail to recognize their cognitive deficits or that the association between subjective and objective cognition is weak in schizophrenia. The reasons for this lack of consistency remain unexplained but may have to do, among others, with the influence of potential confounding clinical variables and the choice of the scale used to measure self-awareness of cognitive deficits. In the current study, we sought to examine the relationships between subjective and objective cognitive performance in schizophrenia, while controlling for the influence of sociodemographic and psychiatric variables. Eighty-two patients with a schizophrenia-spectrum disorder (DSM-IV criteria) were recruited. Patients' subjective cognitive complaints were evaluated with the Subjective Scale to Investigate Cognition in Schizophrenia (SSTICS), the most frequently used scale to measure self-awareness of cognitive deficits in schizophrenia. Neurocognition was evaluated with working memory, planning and visual learning tasks taken from Cambridge Neuropsychological Tests Automated Battery. The Stroop Color-Word test was also administered. Psychiatric symptoms were evaluated with the Positive and Negative Syndrome Scale and the Calgary Depression Scale for Schizophrenia. The relationships between subjective and objective cognition were evaluated with multivariate hierarchic linear regression analyses, taking into consideration potential confounders such as sociodemographic and psychiatric variables. Finally, a factor analysis of the SSTICS was performed. For the SSTICS total score, the regression analysis produced a model including two predictors, namely visual learning and Stoop interference performance, explaining a moderate portion of the variance

Another objective was to determine the impact of gender, age, type of residence and taking sleeping medication on the quality of sleep. Design: A cross-sectional study. Methods: Data were collected using the standardized Pittsburgh Sleep Quality Index (PSQI questionnaire. The sample comprised 146 seniors living in the Moravian-Silesian Region, Czech Republic. The survey was conducted from January 2014 to the end of October 2014 in a long-term chronic care department of a selected hospital, two retirement homes and among seniors living in their own homes. Results: Thirty-five (24% seniors had their global PSQI scores of 5 (i.e. the highest score indication good sleep quality or less. The remaining 111 (76% participants were shown to suffer from impaired sleep quality as their global PSQI scores were 6 or higher. There were statistically significant differences in component scores between seniors with the global PSQI scores of 5 or less and those with higher scores. The best quality of sleep was observed in females, seniors in the 65–74 age category and those sharing their own homes with their spouses or partners. Conclusion: Subjective sleep quality assessment varies significantly with respect to gender, age, type of residence and use of sleeping medication. Keywords: sleep quality, PSQI, subjective assessment, senior.

    This study was to identify the efficacy of -80°C cryopreservated peripheral blood hemato-poietic stem cell (PBHSC) transplantation for hematopoietic reanstitution in patients. The efficacy of 104 patients underwent autologous peripheral blood hematopoietic stem cell transplantation using uncontrolled-rate freezing and storage at -80°C was evaluated. This cryopreservation method could effectively cryopreserve peripheral blood stem cells. Out of 104 patients only 2 patients died, other patients got hematologic reconstition satisfactorily, the median engrafement times of neutrophils and platelet were 12 and 14 days respectively, the activity of cells after rehabilitation was 94%, the mean recovery rates of CD34(+) cells and mononuclear cells (MNC) were 86% and 80.3% respectively. There were no significant influences on engrafement time in sex, chemotherapy circles and radiotherapy. The engrafement of leukocytes associated with amount of CD34(+) cells. This simple uncontrolled-rate freezing PBHSC at -80°C is safe, effective and economic, and can meet clinical needs. As compared with the classical cryopreservation, there were no significant differences in hematopoietic reconstitution. Therefore, this method worth to popularize and apply in clinic.

    Fieldwork is one of the important methods in educational, social, and organisational research. In fieldwork, the researcher takes residence for a shorter or longer period amongst the subjects and settings to be studied. The aim of this is to study the culture of people: how people seem to make...... sense of their lives and which moral, professional, and ethical values seem to guide their behaviour and attitudes. In fieldwork, the researcher has to balance participation and observation in her attempts at representation. Consequently, the researcher’s academic and life-historical subjectivity...... are important filters for fieldwork. In general, fieldwork can be understood as processes where field reports and field analysis are determined by how the researcher interacts with and experiences the field, the events and informants in it, and how she subsequently develops an ethnography.

    Full Text Available Um dos procedimentos mais delicados envolvidos numa análise de corpus via palavras-chave com WordSmith Tools KeyWords é a seleção de um sub-conjunto de palavras para serem investigadas em detalhe. A seleção se faz necessária, via de regra, porque o tamanho do léxico chave de um corpus de estudo é em geral muito grande, em geral em torno de 1500 palavras ou até mais. Uma maneira de fazer esse recorte consiste na extração de palavras-chave exclusivas. O léxico chave exclusivo é composto das palavras-chave que ocorrem somente no corpus de estudo em questão em comparação com palavras-chave de outros corpora de estudo. Contudo, comparar a lista de palavras-chave com várias outras é um procedimento custoso e complicado, que não pode ser exigido da maioria dos usuários de WordSmith Tools KeyWords. Uma alternativa para este cenário seria a aplicação de um ponto de corte generalizado baseado em tendências de retorno de palavras-chave observadas através da aplicação do banco de palavras-chave existente. Tal ponto de corte indicaria a região da lista de palavras-chave na qual há maior probabilidade de ocorrência do léxico chave exclusivo. Os resultados obtidos aqui indicam um ponto de corte entre 31% a 53% das palavras da lista, a partir da primeira de uma lista ordenada por chavicidade.One of the most sensitive issues surrounding a keywords analysis with WordSmith Tools is the selection of a subset of words in a corpus that deserve being looked at in greater detail. This selection is normally needed because the size of the key word list can reach several hundred, up to 1,500 or more. One way to extract a selection consists of the pulling out 'exclusive key words'. This key lexis is made up of keywords that only in a single corpus only, in comparison with a bank of keyword lists.

    Objectives Poorly controlled hypertension (HTN) is extremely prevalent and, if left unchecked, subclinical hypertensive heart disease (SHHD) may ensue leading to conditions such as heart failure. To address this, we designed a multidisciplinary program to detect and treat SHHD in a high-risk, predominantly African American community. The primary objective of this study was to determine the cost-effectiveness of our program. Methods Study costs associated with identifying and treating patients with SHHD were calculated and a sensitivity analysis was performed comparing the effect of four parameters on cost estimates. These included prevalence of disease, effectiveness of treatment (regression of SHHD, reversal of left ventricular hypertrophy [LVH], or blood pressure [BP] control as separate measures), echocardiogram costs, and participant time/travel costs. The parent study for this analysis was a single-center, randomized controlled trial comparing cardiac effects of standard and intense (<120/80 mm Hg) BP goals at 1 year in patients with uncontrolled HTN and SHHD. A total of 149 patients (94% African American) were enrolled, 133 (89%) had SHHD, 123 (93%) of whom were randomized, with 88 (72%) completing the study. Patients were clinically evaluated and medically managed over the course of 1 year with repeated echocardiograms. Costs of these interventions were analyzed and, following standard practices, a cost per quality-adjusted life-year (QALY) less than $50,000 was defined as cost-effective. Results Total costs estimates for the program ranged from $117,044 to $119,319. Cost per QALY was dependent on SHHD prevalence and the measure of effectiveness but not input costs. Cost-effectiveness (cost per QALY less than $50,000) was achieved when SHHD prevalence exceeded 11.1% for regression of SHHD, 4.7% for reversal of LVH, and 2.9% for achievement of BP control. Conclusions In this cohort of predominantly African American patients with uncontrolled HTN, SHHD

    The effectiveness of wet grinding (wet dust reduction method) and ventilated grinding (local exhaust ventilation method, LEV) in reducing the levels of respirable crystalline silica dust (quartz) and respirable suspended particulate matter (RSP) were compared with that of uncontrolled (no dust reduction method) conventional grinding. A field laboratory was set up to simulate concrete surface grinding using hand-held angle grinders in an enclosed workplace. A total of 34 personal samples (16 pairs side-by-side and 2 singles) and 5 background air samples were collected during 18 concrete grinding sessions ranging from 15-93 min. General ventilation had no statistically significant effect on operator's exposure to dust. Overall, the arithmetic mean concentrations of respirable crystalline silica dust and RSP in personal air samples during: (i) five sessions of uncontrolled conventional grinding were respectively 61.7 and 611 mg/m(3) (ii) seven sessions of wet grinding were 0.896 and 11.9 mg/m(3) and (iii) six sessions of LEV grinding were 0.155 and 1.99 mg/m(3). Uncontrolled conventional grinding generated relatively high levels of respirable silica dust and proportionally high levels of RSP. Wet grinding was effective in reducing the geometric mean concentrations of respirable silica dust 98.2% and RSP 97.6%. LEV grinding was even more effective and reduced the geometric mean concentrations of respirable silica dust 99.7% and RSP 99.6%. Nevertheless, the average level of respirable silica dust (i) during wet grinding was 0.959 mg/m(3) (38 times the American Conference of Governmental Industrial Hygienists [ACGIH] threshold limit value [TLV] of 0.025 mg/m(3)) and (ii) during LEV grinding was 0.155 mg/m(3) (6 times the ACGIH TLV). Further studies are needed to examine the effectiveness of a greater variety of models, types, and sizes of grinders on different types of cement in different positions and also to test the simulated field lab experimentation in the field.

    Diabetes and prediabetes subjects have increased risk for mortality. We analyzed the mortality risk due to all causes, cardiovascular disease (CVD) and cancer in Korean subjects participating in a health-screening program according to baseline glycemic status and HbA1c levels. Among 241,499 participants of a health-screening program between 2005 and 2012, the risk of death from all causes, CVD, and cancer was calculated based on the baseline glycemic status (normoglycemia, prediabetes, and diabetes) and HbA1c levels. Uncontrolled diabetes was defined as HbA1c≥7.0%. Vital status and confirmation of the cause of death were based on the analysis of death certificate records from the National Death Index. During 923,343.1 person-years of follow-up, 877 participants died. The multivariable-adjusted hazard ratios (HR) of subjects with controlled and uncontrolled diabetes to normoglycemic subjects for all-cause mortality were 1.58 (95% CI 1.24-2.03) and 2.26 (95% CI 1.78-2.86), respectively. The HRs of subjects with controlled and uncontrolled diabetes to normoglycemic subjects for mortality due to cancer were 1.75 (95% CI 1.23-2.48) and 1.67 (95% CI 1.13-2.45). However, glycemic status was not significantly associated with the risk of mortality due to CVD. The subjects with HbA1c higher than 6.5% showed more than 2-fold increased risk for all-cause mortality and the subjects with HbA1c lower than 5.2% showed increased HR (1.45, 95% CI 1.06-1.97) compared with those with HbA1c of 5.5% in subjects not taking anti-diabetic medications. Mortality risk from all causes and cancer significantly increased in diabetes subjects regardless of the glucose control status. In subjects not taking anti-diabetic medications, both high and low HbA1c resulted in increased risk for all-cause mortality. Copyright © 2015 Elsevier Inc. All rights reserved.

    Creation of a central iliac arteriovenous anastomosis using a novel nitinol coupler device results in an immediate, significant reduction of blood pressure (BP). We present efficacy and safety findings at 12 months post-coupler insertion. This open-label, multicenter, prospective, randomized trial enrolled patients with a baseline office systolic BP ≥140 mm Hg and average daytime ambulatory BP ≥135/85 mm Hg. Subjects were randomly allocated to coupler implantation and continuing previous pharmacotherapy or to maintain previous treatment alone. At 12 months, 39 patients who had coupler therapy were included in the intention-to-treat analysis. Office-based systolic BP reduced by 25.1±23.3 mm Hg (baseline, 174±18 mm Hg; PURL: http://www.clinicaltrials.gov. Unique identifier: NCT01642498. © 2017 American Heart Association, Inc.

In the context of contemporary nihilism, the decoding of the mechanisms which consign praxis to the practico-inert requires a critique of the relations between the social sciences and philosophy, which in its turn implies a new theory of the relation between what Sartre calls the "notion" (the area of subjectivity and the "concept" (objectivity, From this perspective, the deconstruction of the established frontiers between the social sciences and philosophy, and between the conceptual and the narrative, is corelative to a redefinition of the relation between theory and practice.

    Carboxylic acid production from food waste by mixed culture fermentation is an important future waste management option. Obstacles for its implementation are the need of pH control, and a broad fermentation product spectrum leading to increased product separation costs. To overcome these obstacles, the selective production of lactic acid (LA) from model food waste by uncontrolled pH fermentation was tested using different reactor configurations. Batch experiments, semi-continuously fed reactors and a percolation system reached LA concentrations of 32, 16 and 15gCODLA/L, respectively, with selectivities of 93%, 84% and 75% on COD base, respectively. The semi-continuous reactor was dominated by Lactobacillales. Our techno-economic analysis suggests that LA production from food waste can be economically feasible, with LA recovery and low yields remaining as major obstacles. To solve both problems, we successfully applied in-situ product extraction using activated carbon. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The combination of traumatic injury, hemorrhage, and fluid resuscitation results in consumption and dilution of coagulation factors, adversely impacting hematology outcome in trauma patients. The hemostatic effects of escalating doses of recombinant factor VIIa added to hemoglobin-based oxygen carrier-201 were assessed as prehospital fluid resuscitation in swine with severe uncontrolled hemorrhage. Swine underwent liver injury causing severe uncontrolled hemorrhage and shock. During a 4-h prehospital phase, either hypotensive or tachycardic, or both, animals were resuscitated with hemoglobin-based oxygen carrier-201 without (0x) or with escalating doses of recombinant factor VIIa [90 microg/kg (1x), 180 microg/kg (2x), or 360 microg/kg (4x)]. The animals received one initial full dose of 10 ml/kg at 15 min and up to four doses of 5 ml/kg thereafter. From 4 to 72 h (hospital phase), animals received either transfusions or isotonic saline or both as needed. Hematology profile (complete blood count), thromboelastography, in-vitro bleeding (platelet function analyzer), and coagulation (prothrombin time) were measured and the results were compared using mixed statistical models. In all groups, dilutional coagulopathy was evidenced by reduced hematocrit, platelets, and thromboelastography-maximum amplitude, and increased platelet function analyzer closure time and thromboelastography-reaction time. During the prehospital phase, hemoglobin-based oxygen carrier-201 restored hemoglobin in all groups. Recombinant factor VIIa decreased prothrombin time in recombinant factor VIIa groups compared with the hemoglobin-based oxygen carrier-201 group (P 0.05). Compared with hemoglobin-based oxygen carrier, 1x recombinant factor VIIa tended to decrease blood loss, lactate and thromboelastography-reaction time at 24 h but the 4x group increased these parameters. Platelets and thromboelastography-maximum amplitude decreased (P hemoglobin-based oxygen carrier-201 did not change

    Vildagliptin is a dipeptidyl peptidase-4 inhibitor commonly used as a dual oral agent with metformin, thiazolidinediones, or sulfonylurea for the treatment of type 2 diabetes mellitus (T2DM). The efficacy of dual therapy with vildagliptin and metformin has been established in randomized controlled trials, but there is little evidence from observational studies. The aims of the present study were to evaluate the effectiveness of vildagliptin as an add-on therapy to metformin in reducing HbA1c and its affects on body weight and blood lipids in a real-life setting. Included in the present retrospective cohort were T2DM patients (n = 345) who were uncontrolled on metformin monotherapy and intensified treatment with vildagliptin. The efficacy of at least 90 days of dual therapy with vildagliptin and metformin in reducing HbA1c levels, as well as changes in blood lipids and body weight, were evaluated. After 180 days (range 90-365 days) from the index date with a mean daily dose of 92 mg vildagliptin, HbA1c was significantly (P < 0.001) reduced by an average of 0.9% (95% confidence interval -1.0%, -0.7%). The absolute reduction in HbA1c was positively associated with baseline HbA1c levels. In addition to HbA1c, a modest but significant (P < 0.05) decrement was also calculated in the patients' body weight and blood lipids. The present analysis of real-world data corroborates the results of previous randomized controlled trials indicating that add-on therapy with vildagliptin in uncontrolled patients on metformin monotherapy is associated with a significant improvement in the control of HbA1c. © 2017 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

    This study was designed to determine whether or not the addition of a single nighttime dose of doxazosin in extended-release form (GITS; gastrointestinal therapeutic system) would affect the autonomic modulation of the cardiovascular system in patients with uncontrolled hypertension treated with a multi-drug regimen. Resting 5-min noninvasive finger blood pressure and ECG signals, as well as 24-h Holter ECGs, were recorded in 30 patients with uncontrolled hypertension on multi-drug treatment before and after 16-week add-on therapy with doxazosin GITS. Cardiovascular autonomic modulation was evaluated by spectral analysis of heart rate variability (HRV) and a cross-correlation method for spontaneous baroreflex sensitivity (BRS) in 5-min resting recordings, and by the analysis of Poincaré plots and phase-rectified signal averaging of the duration of cardiac cycles in 24-h ECG recordings. This combined therapy significantly reduced systolic pressure (19.4+/-3.5 mmHg; pblood pressure (9.4+/-2.0 mmHg; p=0.0003), and pulse pressure (10.0+/-2.8 mmHg; p=0.0021). Concomitantly, there was a significant increase in resting spontaneous BRS (p=0.0191) and increases in 24-h short-term (p=0.0129) and total (p=0.0153) HRV, but with no significant change in heart rate or other measures of HRV. The improvements in HRV and BRS were observed mainly in patients already treated with thiazide diuretics. There was a significant association (r=0.49; p=0.0065) between the degree of change in diastolic blood pressure and short-term HRV caused by the combined treatment. The addition of 4 mg doxazosin GITS to multi-drug antihypertensive therapy is associated with an improvement in cardiovascular autonomic control.

    Feeding independence is important to improve the quality of life (QOL) of patients receiving palliative care. Studies on feeding independence among cancer patients under palliative care are unavailable. This study aimed to evaluate the effectiveness of occupational therapy in promoting feeding independence in end-stage cancer patients in palliative care. Thirty-six end-stage cancer inpatients with feeding difficulties attributable to improper positioning (58.3%), one-handedness (22.2%), and upper limb impairment (11.1%) were enrolled from two hospitals in Hong Kong. The feeding independence level (level 1> or =25% assistance; level 2feeding aid support (25%), and upper limb support (11%). Multilevel models were used for comparing feeding independence levels at baseline and weekly intervals. There was a significant improvement in feeding independence from baseline to week 1 (Pfeeding independence between weeks 1 and 2 (P=0.246) and between weeks 1 and 3 (P=0.165) among the subjects after controlling for age and sex, indicating that the improved feeding independence in week 1 was sustainable through weeks 2 and 3. The prospective study showed for the first time that the provision of appropriate feeding supports could markedly enhance feeding independence in end-stage cancer patients receiving palliative care, which might improve activities of daily living and QOL, and minimize excessive disability. Furthermore, it merits cooperation among occupational therapists, caregivers, and ward staff to promote feeding independence in this group of patients.

  9. International Energy: Subject Thesaurus

    1990-01-01

    The International Energy Subject Thesaurus contains the standard vocabulary to indexing terms (descriptors) developed and structured to build and maintain energy information databases. Involved in this cooperative task are (1) the technical staff of the USDOE Office of Scientific and Technical Information (OSTI) in cooperation with the member countries of the Energy Technology Data Exchange (ETDE) and (2) the International Nuclear Information System (INIS) staff representing the more than ninety countries and organizations recording and indexing information for the international nuclear information community. ETDE member countries are also members of the International Nuclear Information System (INIS). Nuclear information indexed and recorded for INIS by these ETDE member countries is also included in the ETDE Energy Data Base, and indexing terminology is therefore cooperatively standardized for use in both information systems. This structured vocabulary reflects the scope of international energy research, development, and technological programs and encompasses terminology derived not only from the basic sciences but also from the areas of energy resources, conservation, safety, environmental impact, and regulation.

  10. Naming the Ethological Subject.

    Benson, Etienne S

    2016-03-01

    Argument In recent decades, through the work of Jane Goodall and other ethologists, the practice of giving personal names to nonhuman animals who are the subjects of scientific research has become associated with claims about animal personhood and scientific objectivity. While critics argue that such naming practices predispose the researcher toward anthropomorphism, supporters suggest that it sensitizes the researcher to individual differences and social relations. Both critics and supporters agree that naming tends to be associated with the recognition of individual animal rights. The history of the naming of research animals since the late nineteenth century shows, however, that the practice has served a variety of purposes, most of which have raised few ethical or epistemological concerns. Names have been used to identify research animals who play dual roles as pets, workers, or patients, to enhance their market value, and to facilitate their identification in the field. The multifaceted history of naming suggests both that the use of personal names by Goodall and others is less of a radical break with previous practices than it might first appear to be and that the use of personal names to recognize the individuality, sentience, or rights of nonhuman animals faces inherent limits and contradictions.

  11. A Subjective Rational Choice

    Vinogradov, G. P.

    2017-01-01

    The problem of constructing a choice model of an agent with endogenous purposes of evolution is under debate. It is demonstrated that its solution requires the development of well-known methods of decision-making while taking into account the relation of action mode motivation to an agent’s ambition to implement subjectively understood interests and the environment state. The latter is submitted for consideration as a purposeful state situation model that exists only in the mind of an agent. It is the situation that is a basis for getting an insight into the agent’s ideas on the possible selected action mode results. The agent’s ambition to build his confidence in the feasibility of the action mode and the possibility of achieving the desired state requires him to use the procedures of forming an idea model based on the measured values of environment state. This leads to the gaming approach for the choice problem and its solution can be obtained on a set of trade-off alternatives.

    Full Text Available The specific aspects which determined the way some groups of students conducted their work in a university laboratory, made us understand the articulation of these groups´s dynamics, from elements that were beyond the reach of cognition. In more specific terms the conduction and the maintenance of the groups student´s dynamics were explicited based on a intergame between the non conscious strategies, shared anonymously, and the efforts of the individuals in working based on their most objective task. The results and issues we have reached so far, using a reference the work developed by W.R.Bion, with therapeutical groups, gave us the possibility for understanding the dynamics of the student´s experimental work through a new approach that approximates the fields of cognition and subjectivity. This approximation led us to a deeper reflection about the issues which may be involved in the teaching process, particularly in situations which the teacher deals with the class, organised in groups.

    Full Text Available Higher education can function as an important marker of seriousness in fields characterized by diffuse professional standards. Using the case of a fine arts institute, the article outlines the role of higher education in promoting the interconnection of a professional and individual subjectivity; being an artist is not merely something one does but something one is. By primarily examining interview material, it explores how an ideal position of individual self-reliance relates to the alumni of the institute. Some respondents were not “in sync” with this position and needed to seek out other resources in order to construct themselves as professional artists. However, they seldom rejected the kind of subjectivity promoted by their education, but rather renegotiated it as part of the uncertainty of their chosen field.Keywords: arts professionals, artistic education, self-reliance, discursive repertoire

  20. Subjective cognitive decline: The first clinical manifestation of Alzheimer's disease?

    Directory of Open Access Journals (Sweden)

    Adalberto Studart Neto

    Full Text Available ABSTRACT Background: Mild cognitive impairment is considered as the first clinical manifestation of Alzheimer's disease (AD, when the individual exhibits below performance on standardized neuropsychological tests. However, some subjects before having a lower performance on cognitive assessments already have a subjective memory complaint. Objective: A review about subjective cognitive decline, the association with AD biomarkers and risk of conversion to dementia. Methods: We performed a comprehensive non-systematic review on PubMed. The keywords used in the search were terms related to subjective cognitive decline. Results: Subjective cognitive decline is characterized by self-experience of deterioration in cognitive performance not detected objectively through formal neuropsychological testing. However, various terms and definitions have been used in the literature and the lack of a widely accepted concept hampers comparison of studies. Epidemiological data have shown that individuals with subjective cognitive decline are at increased risk of progression to AD dementia. In addition, there is evidence that this group has a higher prevalence of positive biomarkers for amyloidosis and neurodegeneration. However, Alzheimer's disease is not the only cause of subjective cognitive decline and various other conditions can be associated with subjective memory complaints, such as psychiatric disorders or normal aging. The features suggestive of a neurodegenerative disorder are: onset of decline within the last five years, age at onset above 60 years, associated concerns about decline and confirmation by an informant. Conclusion: These findings support the idea that subjective cognitive complaints may be an early clinical marker that precedes mild cognitive impairment due to Alzheimer's disease.

    Full Text Available Background Fulfilling the learners' "real needs" will improve medical education. There are subjects that are necessary for any clinical residents not considering their field of specialty. Among the subjects ten seems to be the most important: research methodology and data analysis, computer-based programs, medical recording, cardiopulmonary and cerebral resuscitation, clinical teaching programs, communication skills, clinical ethics, laboratory examinations, reporting special diseases and death certification, and prescription. Purpose This cross-sectional study assessed educational needs of clinical residents for ten educational subjects. Methods A questionnaire prepared by board faculty members consisted of 10 close-ended questions, and one open­ ended question was distributed among 1307 residents from 22 clinical disciplines, who registered for preboard or promotion exam in June 2000. Results Among the subjects three were the most needed: computer-based programs 149 (60%, data collecting system 606 (49%, and clinical ethics 643 (46%. The prescription standard was the least required 177(13%. Conclusion Complementary training courses on these subjects can be an answer to the clinical residents needs.

    Full Text Available Although a relatively new discipline, Knowledge Management (KM is an area with a wide range of theoretical concepts and practical implications. The applicability of KM in different environments, and the vast value and benefits of its application, have led to great developments within the discipline over the last few years. The interdisciplinary nature of KM has also provided the opportunity for contributions by people from different disciplines, which in turn has lead to the rapid advancement of KM boundaries. This paper aims to examine the subject structure of the KM discipline through keyword analysis of documents in the Web of Science, using a hierarchical clustering approach and an inclusion index. Within the Web of Science categories, according to the findings, the three categories of "Management", "Computer Science Information Systems" and "Information Science Library Science" claim the highest number of documents in this area. Of 5570 author keywords, , 96 keywords are identified as "highly used" keywords. Three hierarchical clusters (dendrograms are formed from co-occurrence analysis of highly used keywords in the three categories. A comparison of these denrograms indicates that six clusters, including a total of 16 keywords, are common in the three categories. Looking at clusters of the three categories revealed that two categories - Management and Information Science Library Science - have 14 common/shared clusters, and therefore the highest degree of similarities. However, the category of Computer Science Information Systems, with 28 unique clusters, differs most markedly from the other two categories. To investigate the rate of common keywords from one category to another, the inclusion index is calculated. Results of this exercise indicate that the category of Information Science Library Science has the highest number of common keywords.

    To evaluate the efficacy and safety of lacosamide administered as either first add-on or later add-on antiepileptic drug (AED) therapy for patients with uncontrolled partial-onset seizures (POS). In this open-label, multicentre trial, patients with POS initiated oral lacosamide (titrated to 400 mg/day) either as add-on to first AED monotherapy, or as later add-on to 1-3 concomitant AEDs after ≥ 2 previous AEDs. The primary efficacy variable was the proportion of patients achieving seizure freedom for the first 12 weeks of the 24-week Maintenance Phase. 456 patients received ≥ 1 dose of lacosamide (96 as first add-on, 360 as later add-on). In the first add-on cohort, 27/72 (37.5%) patients completed 12 weeks treatment and remained seizure-free; 18/68 (26.5%) remained seizure-free after 24 weeks. 64/91 (70.3%) patients achieved ≥ 50% reduction in seizure frequency during maintenance treatment. This was accompanied by a mean 7.1 ± 16.00 point improvement from Baseline in the Quality of Life Inventory in Epilepsy (QOLIE-31-P) total score for 24-week completers, with improvement reported in all subscales. Most common treatment-emergent adverse events (TEAEs) were dizziness (31.3%) and headache (13.5%). In the later add-on cohort, 39/261 (14.9%) and 29/249 (11.6%) patients remained seizure-free after completing 12 and 24 weeks' treatment, respectively. 178/353 (50.4%) patients achieved ≥ 50% reduction in seizure frequency during maintenance treatment. Mean change in QOLIE-31-P total score was 4.8 ± 14.74 points among 24-week completers. Common TEAEs were dizziness (33.6%), somnolence (15.0%) and headache (11.4%). Lacosamide initiated as first add-on treatment was efficacious and well tolerated in patients with uncontrolled POS. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Current psychological and behavioral therapies for chronic musculoskeletal pain only modestly reduce pain, disability, and distress. These limited effects may be due to the failure of current therapies: a) to help patients learn that their pain is influenced primarily by central nervous system psychological processes; and b) to enhance awareness and expression of emotions related to psychological trauma or conflict. We developed and conducted a preliminary, uncontrolled test of a novel psychological attribution and emotional awareness and expression therapy that involves an initial individual consultation followed by 4 group sessions. A series of 72 patients with chronic musculoskeletal pain had the intervention and were assessed at baseline, post-treatment, and 6-month follow-up. Participation and satisfaction were high and attrition was low. Intent-to-treat analyses found significant improvements in hypothesized change processes: psychological attributions for pain, emotional awareness, emotional approach coping, and alexithymia. Pain, interference, depression, and distress showed large effect size improvements at post-treatment, which were maintained or even enhanced at 6 months. Approximately two-thirds of the patients improved at least 30% in pain and other outcomes, and one-third of the patients improved 70%. Changes in attribution and emotional processes predicted outcomes. Higher baseline depressive symptoms predicted greater improvements, and outcomes were comparable for patients with widespread vs. localized pain. This novel intervention may lead to greater benefits than available psychological interventions for patients with chronic musculoskeletal pain, but needs controlled testing.

    This study aimed to explore the prevalence of, and factors associated with, uncontrolled diabetes mellitus (UDM) in a community setting in Pakistan. A single-center, cross-sectional study, conducted in a community-based specialized care center (SCC) for diabetes in District Central Karachi, in 2003, registered 452 type 2 DM participants, tested for HbA1c and interviewed face-to-face for other information. Logistic regression analysis was conducted to identify factors associated with UDM. Prevalence of UDM among diabetes patients was found to be 38.9% (95% CI: 34.4-43.4%). Multivariable logistic regression model analysis indicated that age diabetes information from a doctor or nurse only (vs. multiple sources) (OR: 1.8; 95% CI: 1.2-2.9), higher monthly treatment cost (OR: 1.3; 95% CI: 1.1-1.6; for every extra 500 PKR), and higher consumption of tea (OR: 1.5; 95% CI: 1.0-2.2; for every 2 extra cups) were independently associated with UDM. The prevalence of UDM was approximately 39% among persons with type 2 diabetes visiting a community based SCC for diabetes. Modifiable risk factors such as sources of diabetes information and black tea consumption can be considered as potential targets of interventions in Karachi. Copyright © 2014 Elsevier Ireland Ltd.

    Takayasu's arteritis (TA) is a chronic, idiopathic, inflammatory disease affecting the aorta and its branches. To date, only one case involving abdominal aortic thrombosis due to TA has been reported. After bilateral artificial subclavian-iliac bypass, a case of abdominal aortic thrombosis due to TA received a delayed diagnosis in a 44-year-old Chinese male who experienced recurrent episodes of heart failure and uncontrolled hypertension with claudication of two extremities. Abdominal color Doppler sonography and computed tomography aortography (CTA) showed occlusion of the abdominal aorta and bilateral renal artery stenosis. After vascular bypass and during 1 year follow-up, his cardiac function improved and blood pressure was well controlled, with reduced serum creatinine. Postoperative CTA still showed abdominal aortic thrombosis resulting in arterial occlusion extending from the left renal artery initial segment level to the bilateral common iliac artery and the bifurcation of the renal artery, except for the vascular bypass. Abdominal aortic thrombosis due to TA is very rare and potentially life threatening, probably becoming an atherosclerosis risk factor. Doppler sonography and CTA results are important for diagnosis. Artificial vascular bypass can be used for TA in debilitated patients with diffuse aortic disease.

  12. Studies on potential emission of hazardous gases due to uncontrolled open-air burning of waste vehicle tyres and their possible impacts on the environment

    Shakya, Pawan R.; Shrestha, Pratima; Tamrakar, Chirika S.; Bhattarai, Pradeep K.

    Uncontrolled open-air burning of waste vehicle tyres causing environmental pollution has become a popular practice in Nepal despite official ban considering the environment and public health hazards. In this study, an experimental model was set up in a laboratory scale in an attempt to understand the potential emission of hazardous gases such as CO, SO 2 and NO 2 due to such activities in Kathmandu Valley and their possible impacts on the environment. For this purpose, four types of tyre were collected representing two from passenger car and two from motorbike category. The emission level of CO in the tyre smoke was measured with a CO gas detector tube while SO 2 and NO 2 were determined by UV-visible spectrophotometer. Among the three types of the gases analyzed, SO 2 was emitted in significantly high levels by all the representative tyre samples. The emission levels of CO, SO 2 and NO 2 ranged from 21to 49, 102to 820 and 3to 9 μg g -1, respectively. Results revealed that the emission levels also varied with the tyre types and qualities. The potential emission of the hazardous gases per representative scrap tyre mass was also estimated. Results indicate that the gaseous pollutants due to the tyre fires could make a significant contribution for deterioration of the environmental condition of the Valley or elsewhere.

    The results of observational investigation by prescription of the fixed combination perindopril + amlodipin produced by to the uncontrollable hypertension patients by the previous therapy are described in the given article. In Kazan population 50 patients at the age of 32 to 92 with essential hypertension having blood pressure level of 140/90 mm/hg. Were included into the investigation. Before these patients took different groups of antihypertension preparation (including perindopril). The preparation was prescribed in different fixed dosage depending on duration of hypertension, quantity of taken hypertension groups of preparations and blood pressure level. Then during 1, 2, 3 months of treatment the physician had the possibility to determine the dosage necessary to prescribe. The prescription of perindopril in combination with amlodipin during 3 months led to certain lowering of systolic and diastolic arterial pressure for 38.2 and 11.6 mm/hg accordingly and 80% of patients had the required pressure level of (antihypertension therapy till the end of observation. As a result, the investigation confirmed the high efficiency, good perception, improvement of patient compliance for treatment by prescribing the fixed combination perindopril + amlodipin.

    Full Text Available Juvenile primary hypothyroidism causing cystic ovaries and pseudoprecocious puberty (Van-Wyk Grumbach syndrome (VWGS is well documented in literature. There are only a few reports of primary hypothyroidism presenting as ovarian cysts in adults. Here we present a case of huge bilateral ovarian cysts in adulthood as the presenting feature of VWGS due to chronic uncontrolled juvenile hypothyroidism. Large uniloculor right ovarian cyst (119 × 81 × 90 mm and a multicystic left ovary (55 × 45 × 49 mm were detected in a 24 year lady with secondary amenorrhea, galactorrhea, and palpable abdominal mass with history of neonatal jaundice, delayed milestones, short stature, and precocious menarche at age of 7.5 years age. She had elevated levels of cancer antigen (CA-125 which normalized post levothyroxine supplementation. Elevated CA-125 may lead to misdiagnosis of ovarian carcinoma and inadvertent treatment. Bilateral ovarian cysts in adults are a rare presentation of juvenile hypothyroidism. It is necessary to screen for primary hypothyroidism in patients presenting with bilateral ovarian cysts to prevent unnecessary evaluation and treatment.

    Full Text Available This case report illustrates the use of ExPRESS mini-shunt in a pediatric glaucoma patient. We describe the management of steroid-induced glaucoma with ExPRESS mini-shunt in a 9-year-old boy with allergic keratoconjunctivitis. The intraocular pressure of both of his eyes was uncontrolled with medical and laser treatment. Both eyes were treated with ExPRESS mini-shunt and mitomycin-C. Transient overfiltration with postoperative hypotony occurred in both eyes and resolved after 2 weeks. One year postoperatively, intraocular pressure was maintained below 21 mm Hg without medication in 1 eye. Bleb needling with mitomycin-C was done to maintain filtration. The fellow eye received cataract extraction but developed bleb failure a few months afterwards. The intraocular pressure was controlled medically. To conclude, ExPRESS mini-shunt is a new surgical option in selected patients. Bleb failure developed after cataract extraction. Postoperative inflammation should be minimized. Patient selection, such as those with stable ocular condition, is important to increase surgical success.

    The purpose of this study was to evaluate musculoskeletal injury rate and physical fitness before and 6 months after an endurance, strength, and motor control exercise program in preprofessional dancers. This uncontrolled trial was completed at a college offering a professional bachelor degree in dance. Forty preprofessional dancers underwent a test battery before and after a 6-month lasting exercise program in addition to their regular dance lessons. Physical fitness was evaluated by means of a submaximal exercise test with continuous physiological monitoring and by a field test for explosive strength. Anthropometric measurements were taken to analyze the influence of fitness training on body composition. Musculoskeletal injury incidence and quality of life were recorded during the 6-month lasting intervention. An intention-to-treat analysis ("last observation carried forward" method) was used with a Student t test for normally distributed variables. The Wilcoxon signed rank and Mann-Whitney U tests were used as nonparametric tests. Physical fitness improved after the 6 months of additional training program (Pdancing. The combination of regular dance lessons with an additional exercise program resulted in improved physical fitness in preprofessional dancers, without affecting the aesthetical appearance. A relatively high injury rate was observed during the intervention period. These results suggest that a randomized, controlled trial should be performed to examine the effectiveness of additional exercise in dancers on physical fitness and musculoskeletal injury rate.

    To evaluate the relationship between objectively measured memory functions and subjective complaints of memory disturbance and whether subjective complaints are affected by some personality traits or affective states. Cross-sectional two-group comparison. The city of Kuopio in Eastern Finland, considered representative of the urban elderly population of Finland. Originally 403 subjects aged 67-78 years from the random sample and then two matched study groups initially including eighteen subjects but only ten in the final analysis. Screening and follow-up examinations of subjects with and without subjective memory complaints: (1) Memory functions: Benton's visual retention test and the paired-associated learning subtest of Wechsler Memory Scale. (2) Memory complaints: Memory Complaint Questionnaire. (3) Personality traits and affective state: Two subscales from Minnesota Multiphasic Personality Inventory and Geriatric Depression Scale. Complaints of memory loss did not correlate with the actual memory performance in the tests. However, those subjects who most emphatically complained of memory disturbance had greater tendencies toward somatic complaining, higher feelings of anxiety about their physical health, and more negative feelings of their own competence and capabilities than those who did not complain of memory deterioration associated with aging. The study suggests that subjective feelings of memory impairment are more closely associated with personality traits than with actual memory performance in normal elderly people.

    Full Text Available BACKGROUND: We have recently shown a high prevalence of diabetes and obesity in rural Cameroon, despite an improved lifestyle. Diabetes in rural Africa remains underdiagnosed and its role in increasing risk of atherosclerosis in these populations is unknown. We investigated the prevalence of carotid atherosclerosis and cardiovascular risk factors in a population of subjects with recently-diagnosed diabetes from rural Cameroon. METHODOLOGY/PRINCIPAL FINDINGS: In a case-control study, carotid intima-media thickness (IMT was measured in 74 subjects with diabetes (diagnosed 0.9 mm was found in 4%, 45.9% and 20% of diabetic subjects at the common, bulb or internal carotid, respectively. Only 25% of patients had an HbA1c9%. The prevalence of diabetic subjects with abnormal levels of LDL-cholesterol, triglycerides, HDL-cholesterol or blood pressure was 45%, 16.6%, 15% and 65.7%, respectively. CONCLUSIONS: Carotid thickness is increased in subjects with diabetes from a rural area of Cameroon, despite the relatively recent diagnosis. These findings and the high rate of uncontrolled diabetes in this population support the increasing concern of diabetes and cardiovascular diseases in African countries and indicate the need for multifaceted health interventions in urban and rural settings.

  1. The Subject in Cognitive Psychotherapy

    2015-05-01

    Full Text Available This paper discusses the various subjects embedded in cognitive psychotherapy. The cognitive model developed by Beck, considered as a rationalist and modernist model, will exemplify these subjects. Cognitive therapy should be placed in the modernist historical context and related to a subject characterized as having rationality and the ability to observe and detect cognitions, emotions and behaviors. The paper develops this background introducing three main subject types. The first is the introspective and conscious subject, who is able to observe what is within oneself, has free access, and is conscious of one's cognitive world. The second is the cognitive miser that describes the subject who enters into therapy. The final subject identified, is the trained scientist who is able to develop a more objective knowledge, changing faulty schemas and cognitive distortions. This subject is the one most looked for in cognitive therapy. We could connect these subjects to some of the main elements of cognitive therapy such as the concept of ABC, assessment procedures, cognitive techniques or the relevance of schemas. Finally, the paper suggests some issues for study that could contribute to the theoretical and clinical evolution of cognitive psychotherapy.

The study sample consisted of 201 subjects admitted to nursing homes. For the purpose of the present study each subject was evaluated using the Mini-Mental State Examination, the Geriatric Depression Scale, and the Modified Overt Aggression Scale. The results show that aggressive behavior and depressive symptoms are associated with progressive cognitive decline in elderly subjects. Early assessment of these conditions can promote rational therapeutic strategies that may improve the quality of life and delay institutionalization for elderly patients.Keywords: neuropsychiatric symptoms, dementia, behavioral and psychological syndromes of dementia (BPSD, progressive cognitive decline

    Full Text Available Objectives: To evaluate the opticians’ perspective about selling and applying contact lenses (CL in the provincial centre of Mersin. Materials and Methods: Twenty opticians who work in the 4 main districts in the provincial centre of Mersin were included in the study. A questionnaire form which was prepared before was filled out by the participants. Results: Seventy-eight percent of the opticians were selling CL without prescription, whereas 25% also carried out its fitting. Seventyfive percent of the participants did not get any education about contact lenses, while 65% of them were feeling themselves disqualified about CLs. Furthermore, half of the participants did not have enough knowledge about the complications associated with CL usage and 75% of them wanted to receive information about CLs. Conclusion: As a result of the questionnaire, we found out that a significant part of the participants were both selling and fitting contact lenses without prescription. We believe that auditing the opticians is as important as educating the contact lens users. (Turk J Ophthalmol 2015; 45: 102-104

    2007-06-01

    Full Text Available Abstract Based on the distinction between living body and lived body, we describe the disease-subject as representing the impact of disease on the existential life-project of the subject. Traditionally, an individual's subjectivity experiences disorders of the body and describes ensuing pain, discomfort and unpleasantness. The idea of a disease-subject goes further, representing the lived body suffering existential disruption and the possible limitations that disease most probably will impose. In this limit situation, the disease-subject will have to elaborate a new life-story, a new character or way-of-being-in-the-world, it will become a different subject. Health care professionals need to realize that patients are not mere observers of their body, for they are immersed in a reassesment of values, relationships, priorities, perhaps even life-plans. Becoming acquainted with literature's capacity to create characters, modify narratives and depict life-stories in crisis, might sharpen physicians' hermeneutic acumen and make them more receptive to the quandaries of disease-subjects facing major medical and existential decisions in the wake of disruptive disease.

    BACKGROUND: Asthma is a known risk factor for acute ozone-associated respiratory disease. Ozone causes an immediate decrease in lung function and increased airway inflammation. The role of atopy and asthma in modulation of ozone-induced inflammation has not been determined. OBJECTIVE: We sought to determine whether atopic status modulates ozone response phenotypes in human subjects. METHODS: Fifty volunteers (25 healthy volunteers, 14 atopic nonasthmatic subjects, and 11 atopic asthmatic subjects not requiring maintenance therapy) underwent a 0.4-ppm ozone exposure protocol. Ozone response was determined based on changes in lung function and induced sputum composition, including airway inflammatory cell concentration, cell-surface markers, and cytokine and hyaluronic acid concentrations. RESULTS: All cohorts experienced similar decreases in lung function after ozone. Atopic and atopic asthmatic subjects had increased sputum neutrophil numbers and IL-8 levels after ozone exposure; values did not significantly change in healthy volunteers. After ozone exposure, atopic asthmatic subjects had significantly increased sputum IL-6 and IL-1beta levels and airway macrophage Toll-like receptor 4, Fc(epsilon)RI, and CD23 expression; values in healthy volunteers and atopic nonasthmatic subjects showed no significant change. Atopic asthmatic subjects had significantly decreased IL-10 levels at baseline compared with healthy volunteers; IL-10 levels did not significa

    Structural control systems are considered an effective alternative for reducing vibrations in civil structures and are classified according to their energy supply requirement: passive, semi-active, active and hybrid. Commonly used structural control systems in buildings are passive friction dampers, which add energy dissipation through damping mechanisms induced by sliding friction between their surfaces. Semi-Active Variable Friction Dampers (SAVFD) allow the optimum efficiency range of friction dampers to be enhanced by controlling the clamping force in real time. This paper describes the development and performance evaluation of a low-cost SAVFD for the reduction of vibrations of structures subject to earthquakes. The SAVFD and a benchmark structural control test structure were experimentally characterized and analytical models were developed and updated based on the dynamic characterization. Decentralized control algorithms were implemented and tested on a shaking table. Relative displacements and accelerations of the structure controlled with the SAVFD were 80% less than those of the uncontrolled structure

    To compare strength and endurance variables obtained in the quadriceps muscles of postpolio and control subjects over a 7-year interval with macro and single fiber electromyography (EMG) variables. A controlled inception cohort study. Neuromuscular research laboratory of a university hospital. A cohort of 23 postpolio and 14 control subjects. All postpolio subjects had a history, physical examination, and EMG consistent with previous poliomyelitis, and had greater than antigravity strength in the quadriceps muscle tested. Unstable postpolio subjects acknowledged new quadriceps weakness over the 7-year period of the study (n = 11), and stable postpolio subjects denied new weakness of the quadriceps over the same period (n = 12). All subjects had tests of neuromuscular function of the quadriceps muscles at the onset of this study and yearly over a 7-year period. EMG variables were determined on a separate day after the seventh year of neuromuscular measurements. Neuromuscular variables measured were isometric knee extension peak torque, isometric endurance (time to inability to maintain knee extensor contraction at 40% of maximal torque), tension time index (TTI) (product of isometric endurance time and 40% of maximal torque), and recovery of torque at 10 minutes after the endurance test. EMG variables were macro EMG and single fiber EMG (jitter, fiber density, and percent blocking). Unstable postpolio subjects did not lose strength more rapidly than stable postpolio subjects or control subjects. Unstable postpolio subjects were significantly weaker, had decreased TTI, larger macro EMG amplitude, greater jitter, blocking, and fiber density in comparison with stable postpolio subjects (all p postpolio group (p .05) with neuromuscular or EMG variables in control, stable, or unstable postpolio subjects.

  11. When does stress help or harm? The effects of stress controllability and subjective stress response on stroop performance.

    The ability to engage in goal-directed behavior despite exposure to stress is critical to resilience. Questions of how stress can impair or improve behavioral functioning are important in diverse settings, from athletic competitions to academic testing. Previous research suggests that controllability is a key factor in the impact of stress on behavior: learning how to control stressors buffers people from the negative effects of stress on subsequent cognitively demanding tasks. In addition, research suggests that the impact of stress on cognitive functioning depends on an individual's response to stressors: moderate responses to stress can lead to improved performance while extreme (high or low) responses can lead to impaired performance. The present studies tested the hypothesis that (1) learning to behaviorally control stressors leads to improved performance on a test of general executive functioning, the color-word Stroop, and that (2) this improvement emerges specifically for people who report moderate (subjective) responses to stress. Experiment 1: Stroop performance, measured before and after a stress manipulation, was compared across groups of undergraduate participants (n = 109). People who learned to control a noise stressor and received accurate performance feedback demonstrated reduced Stroop interference compared with people exposed to uncontrollable noise stress and feedback indicating an exaggerated rate of failure. In the group who learned behavioral control, those who reported moderate levels of stress showed the greatest reduction in Stroop interference. In contrast, in the group exposed to uncontrollable events, self-reported stress failed to predict performance. Experiment 2: In a second sample (n = 90), we specifically investigated the role of controllability by keeping the rate of failure feedback constant across groups. In the group who learned behavioral control, those who reported moderate levels of stress showed the greatest Stroop

This prospective, uncontrolled, open-label study was conducted in 12 medical centres in China, between January and December 2011. According to the diagnosis criteria of Chinese Guidelines on Urological Infections, patients (18-70 years) with acute uncomplicated cystitis, recurrent lower urinary tract infection or complicated lower urinary tract infection received three doses of 3 g fosfomycin tromethamine orally, at days 1, 3 and 5. Efficacy endpoints (clinical efficacy, microbiological efficacy and overall efficacy) were evaluated on day 15. Clinical symptoms, physical signs, urinalysis, liver and kidney function, patient records and evaluation of adverse events (AEs) and serious AEs up to day 15 were evaluated for analysis of safety. 361 patients were included in the full analysis set, 356 in the safety analysis set and 335 in the per-protocol set (PPS). In the PPS, the clinical efficacy rates at day 15 for acute uncomplicated cystitis, recurrent lower urinary tract infection and complicated lower urinary tract infection were 94.71% (179/189), 77.22% (61/79) and 62.69% (42/67), respectively. The microbiological efficacy rates (day 15) were 97.65% (83/85), 94.44% (34/36) and 83.87% (26/31), respectively. The overall efficacy rates (day 15) were 95.29% (81/85), 77.78% (28/36) and 64.52% (20/31), respectively. 20/356 (5.6%) patients reported drug-related AEs, the most common being diarrhoea. No serious drug-related AEs were reported. This fosfomycin tromethamine dosing regimen showed clinical and microbiological efficacy with some AEs and good tolerability in patients with acute uncomplicated cystitis, recurrent lower urinary tract infection and complicated lower urinary tract infection.

    Depression and obesity frequently co-occur, but providing adequate treatment to depressed obese women is challenging because existing treatments for each problem in isolation are suboptimal, and treatments to address one problem may exacerbate the other. This study used an uncontrolled, pretreatment-to-posttreatment design, with 3-month follow-up, to evaluate the feasibility and outcome of a novel, self-acceptance-based treatment for obese women with depression, "Accept Yourself!" Accept Yourself! is an 11-week manualized, group-based intervention that integrates Health At Every Size (an evidence-based paradigm to enhance physical health) and Acceptance and Commitment Therapy (an evidence-based psychotherapy often used to treat depression and eating-related concerns) to improve the physical and mental health of obese, depressed women without encouraging weight loss. Twenty-one obese women with Major Depressive Disorder received the intervention; 18 completed at least seven sessions, a minimal dose of the intervention. Depressive symptoms, depression diagnosis, physical health outcomes (including physical activity and blood pressure), and obesity-related quality of life were assessed at baseline, posttreatment, and 3-month follow-up. Weight was also monitored. Depression, blood pressure, and obesity-related quality of life significantly improved from pretreatment to posttreatment, and improvements were sustained over a 3-month follow-up. Participants did not gain significant weight during the intervention or at follow-up. These data, although preliminary and nonexperimental, suggest that Accept Yourself! could be a promising treatment for obese, depressed women, and support the value of larger randomized controlled trials.

    The effects of many single stressors have been reported, but how pigs perform when subjected to more than one or two stressors at a time, as is common in commercial swine production, has not. To study this, 256 Yorkshire x Hampshire or purebred Duroc pigs (34.7+/-.5 kg) were subjected to one of the eight treatment combinations (2 x 2 x 2 factorial) of ambient temperature (constant thermoneutral [24 degrees C] or high cycling temperature [28 to 34 degrees C]), stocking density (.56 or .25 m2/pig), and social group (static group or regrouped at the start of wk 1 and 3) during a 4-wk experiment. The temperature regimens were imposed in two adjacent mechanically ventilated rooms, and each temperature was imposed in each room across two trials. Four barrows and four gilts were assigned to each of the eight pens in the two rooms, and they always had free access to water and a corn-soybean meal-based diet. Treatments were imposed after a 7-d acclimation period at 24 degrees C and .56 m2/pig. Weight gain and feed intake were measured weekly. The main effects of each of the stressors for 4-wk ADG and ADFI were significant (P stressor interactions for ADG, ADFI, and gain:feed (G:F), there were no significant three-way interactions and only six two-way interactions, suggesting that the effects of the individual stressors were additive. Accordingly, the growth rate of pigs subjected to the single stressor of high cycling temperature, restricted space allowance, or regrouping was depressed 10, 16, and 11%, respectively, and ADG of pigs subjected to all three stressors simultaneously was depressed by 31%. Stressor additivity was further corroborated by examining the effect of stressor order, or the number of stressors imposed simultaneously. As the number of stressors increased from 0 to 3, ADG, ADFI, and G:F decreased linearly. These data suggest that multiple concurrent stressors affect growth performance of pigs in a predictable fashion (i.e., additively) and indicate that

  15. Is Piaget's epistemic subject dead?

    Science.gov (United States)

    Lawson, Anton E.

    Niaz (1990) presents arguments in favor of the retention of Piaget's epistemic subject as a theoretical construct to guide research and practice in science education and psychology. The intent of this article is to point out the weaknesses of those arguments and to suggest that the weight of evidence argues against the existence of the logical thinker postulated by Piaget. Therefore, contrary to Niaz's conclusion that the acceptance of Piaget's epistemic subject will facilitate the development of cognitive theories with greater explanatory power, the conclusion is reached that Piaget's epistemic subject is dead and that continued acceptance of this aspect of Piagetian theory would be counterproductive.

    Forty-three subjects worked in a private office with switchable electrochromic windows, manually-operated Venetian blinds, and dimmable fluorescent lights. The electrochromic window had a visible transmittance range of approximately 3-60%. Analysis of subject responses and physical data collected during the work sessions showed that the electrochromic windows reduced the incidence of glare compared to working under a fixed transmittance (60%) condition. Subjects used the Venetian blinds less often and preferred the variable transmittance condition, but used slightly more electric lighting with it than they did when window transmittance was fixed.

    The aim of this observational study was to describe the profile of subjects with type 2 diabetes mellitus from Gujarat, India. The study was performed with newly-diagnosed 622 type 2 diabetic subjects who attended the Department of Diabetology, All India Institute of Diabetes and Research and Yash Diabetes Specialties Centre (Swasthya), Ahmedabad, during August 2006-January 2009. The subjects completed an interviewer-administered questionnaire. The questionnaire included variables, such as sociodemographic factors, presenting symptoms, risk profile (hypertension, obesity, dyslipidaemia, and glycaemic status), family history of diabetes, physical activity, and behavioural profile. Blood pressure, body mass index (BMI), glycosylated haemoglobin levels, and fasting lipid profile were measured. Descriptive and bivariate analyses were carried out using the SPSS software (version 11.5). In total; 622 type 2 diabetes mellitus (T2DM) cases with mean age of 47.7 +/- 10.9 years were studied. Of the 622 subjects, 384 (62%) were male. The majority (68%) of the T2DM subjects were obese, and 67% had a positive family history of diabetes. Renal dysfunctions and vision impairment were, respectively, found in 10% (n=62) and 9% (n=57) of the 622 T2DM subjects. The mean HbAlc level was 9.02 +/- 1.67%, and good glycaemic control (HbAlc level or =25 kg/m2) was significantly associated with hypertension among the T2DM subjects (p family history of diabetes, dyslipidaemia, uncontrolled glycaemic status, sedentary lifestyles, and hypertension were prevalent among the T2DM subjects. The characterization of this risk profile will contribute to designing more effective and specific strategies for screening and controlling T2DM in Gujarat, India.

    To evaluate the prevalence of masked uncontrolled and treated white-coat hypertension defined according to the average of morning and evening home blood pressure values. The study population consisted of 3303 essential hypertensive outpatients receiving antihypertensive treatment in Japan. Information on the characteristics of the patients was collected by a physician's self-administrated questionnaire. The office blood pressure value was calculated as the average of the four readings in two visits. All patients were asked to measure their blood pressure once every morning and once every evening. In the study, we included patients with at least three measurements in the morning and in the evening, respectively. The average of all home blood pressure values was taken as the home blood pressure value. The mean value of home systolic/diastolic blood pressure was 136.8/79.3 mmHg, and the mean value of office systolic/diastolic blood pressure was 142.8/80.6 mmHg. Of the 3303 patients, 758 (23.0%) had controlled hypertension (home office home > or =135/85 mmHg and office home office > or =140/90 mmHg), and 1277 (38.7%) had uncontrolled hypertension (home > or =135/85 mmHg and office > or =140/90 mmHg). Treated white-coat hypertension and masked uncontrolled hypertension were often observed in clinical settings. Physicians need to understand the prevalence of such patients to prevent inadequate diagnosis and treatment in them.
