Clinical profile, management, and outcome in patients with out of hospital cardiac arrest: insights from a 20-year registry

Background There is limited information regarding the clinical characteristics and outcome of out of hospital cardiac arrest (OHCA) in Middle Eastern patients. The aim of this study was to evaluate clinical characteristics, treatment, and outcomes in patients admitted following OHCA at a single center in the Middle East over a 20-year period. Methods The data used for this hospital-based study were collected for patients hospitalized with OHCA in Doha, Qatar, between 1991 and 2010. Baseline clinical characteristics, in-hospital treatment, and outcomes were studied in comparison with the rest of the admissions. Results A total of 41,453 consecutive patients were admitted during the study period, of whom 987 (2.4%) had a diagnosis of OHCA. Their average age was 57±15 years, and 72.7% were males, 56.5% were Arabs, and 30.9% were South Asians. When compared with the rest of the admissions taken as a reference, patients with OHCA were more likely to have diabetes mellitus (42.8% versus 39.1%, respectively, P=0.02), prior myocardial infarction (21.8% versus 19.2%, P=0.04), and chronic renal failure (7.4% versus 3.9%, P=0.001), but were less likely to have dyslipidemia (16.9% versus 25.4%, P=0.001). Further, 52.6% of patients had preceding symptoms, the most common of which was chest pain (27.2%) followed by dyspnea (24.8%). An initially shockable rhythm (ventricular fibrillation or ventricular tachycardia) was present in 25.1% of OHCA patients, with ST segment elevation myocardial infarction documented in 30.0%. Severely reduced left ventricular systolic function (ejection fraction ≤35%) was present in 53.2% of OHCA patients; 42.9% had cardiogenic shock requiring use of inotropes at presentation. An intra-aortic balloon pump was inserted in 3.6% of cases. Antiarrhythmic medications were used in 27.4% and thrombolytic therapy in 13.9%, and 10.8% underwent a percutaneous coronary procedure (coronary angiography ± percutaneous coronary intervention). The in-hospital mortality rate was 59.8%. Conclusion OHCA was associated with higher incidences of diabetes, prior myocardial infarction, and chronic kidney disease as compared with the remaining admissions. Approximately half of the patients had no preceding symptoms. In-hospital mortality was high (59.8%), but similar to the internationally published data.
Truthtelling in Matching Markets

We analyze a search and matching model with non-transferable utility and asymmetric information. Randomly paired agents go through an evaluation phase, at the end of which they discover each other's types and choose to match or not. Before deciding to enter this phase, agents can communicate through cheap talk. We provide conditions for this communication to be informative, and we examine how it affects agents' welfare. We show that communication is Pareto-improving only when the matching is assortative in the absence of communication and left unchanged by information transmission.
Alterations of the plasma lipoproteins and apoproteins following cholesterol feeding in the rat.

The feeding of cholesterol to rats resulted in marked alterations in the type and distribution of the plasma lipoproteins and their apoproteins. The hyperlipoproteinemia was characterized by an increase in the d < 1.006 lipoproteins (B-VLDL and VLDL), an increase in the intermediate and low density lipoproteins (LDL), and the appearance of HDL(c). Associated with these lipoproteins was a prominence of the arginine-rich apoprotein. The high density lipoproteins (HDL) were decreased. A two-dimensional immunoelectrophoretic procedure was adapted to quantitate the changes in distribution of the arginine-rich apoprotein in the plasma and various ultracentrifugal fractions obtained from control and cholesterol-fed rats. In rats fed the cholesterol diet, the total plasma arginine-rich apoprotein increased from a control value of approximately 29 mg/dl to 47 mg/dl. The method of ultracentrifugation, however, was found to markedly alter the quantitative results. When the 60 Ti rotor was used at maximum speed to isolate the ultracentrifugal fractions, less than 50% of the total plasma arginine-rich apoprotein was associated with the lipoproteins in the d < 1.006 or the d 1.006-1.02, 1.02-1.063, or 1.063-1.21 ultracentrifugal fractions. By contrast, after limited ultracentrifugation with the 40 rotor, much less arginine-rich apoprotein was lost, with approximately 20% of the arginine-rich apoprotein in control rats and 10% in cholesterol-fed rats found in the d > 1.21 fraction. Significant alterations in the arginine-rich apoprotein quantitation notwithstanding, the observations of increased arginine-rich apoprotein in the B-VLDL, intermediate fraction, and HDL(c) following cholesterol feeding remained valid. However, precise quantitation awaits refinements in lipoprotein isolation techniques.
The Effects of Visual and Auditory Dual-task on Multiple Object Tracking Performance: Interference or Promotion?

Multiple Object Tracking(MOT) developed by Pylyshyn and Storm(1988) has been widely used in the study of capacity-limited and object-based attention. Many researchers interested in finding out whether or not the tracking processes in MOT occupy attentional resource and what type of resource is used. The typical paradigm used in this line of research is dual-task paradigm. Participants were asked to perform a visual or auditory task and the MOT task simultaneously. MOT performance was interfered by both the visual and the auditory task. However, the interference of visual task and auditory task with MOT occurred at different levels. The previous studies demonstrated that the MOT task and visual task occupy visual attention resources. Although the MOT task and auditory task don't occupy visual attention resources, they share more central attention resources(such as executive function). Multiple Identity Tracking(MIT) is a variant of MOT, in which each object carries a unique identity. The previous studies also included both visual or auditory task and MIT task, but those studies have not examined how the visual/auditory task affects the MIT task when the two tasks shared the same properties. The current study included 3 experiments and aimed to investigate the influence of a visual or auditory task on either MOT or MIT task. The first two experiments manipulated participants' eye movement to compare the different effects of visual task and auditory task on MOT performance. The result of experiment 1A showed that the auditory task interfered more with MOT than did the visual task when eyes were fixated at the center of the screen. However, the auditory task yielded less interference with MOT when there was no eye movement control in experiment 1B. The results indicated that the tracking processes in MOT not only occupy visual attention resources, but also occupy central attention resources(such as executive function). The experiment 2 applied visual and auditory digit judgment task and MIT task. When the object identity(marked by a digit) was identical to the number in the digit judgment, the MIT performance was facilitated by both the visual and auditory task. It is possible that the process of digit activated the target identities(the same digits) that was stored in visual working memory during tracking.
Genetic Alterations in Presumptive Precursor Lesions of Breast Carcinomas

The hypothetical multistep model of breast carcinogenesis suggests a transition from normal epithelium to invasive carcinoma via intraductal hyperplasia (without and with atypia) and in situcarcinoma. These presumptive precursor lesions are currently defined by their histological features, and their prognosis is imprecisely estimated from indirect epidemiological evidence. Cytogenetic and molecular‐genetic analysis of these lesions give evidence for an accumulation of various genetic alterations during breast tumorigenesis. Using immuno‐histochemistry overexpression of the c‐erbB‐2 oncogene was found in ductal carcinoma in situ(DCIS), but not in atypical intraductal hyperplasia (AIDH) and intraductal hyperplasia (IDH). An expression of mutant p53 tumor suppressor gene as well as expression of cyclin D1 was identified in DCIS. In IDH lesions loss of heterozygosity (LOH) at various loci could be identified, and comparative genomic hybridization (CGH) and fluorescence in situhybridization (FISH) studies delivered evidence for DNA amplification on chromosomal region 20q13 in the early stage of IDH. However, little is currently known about genetic alterations in those premalignant lesions, and the chronology of genetic alterations and histopathological changes during carcinogenesis is mainly undiscovered.

Healthy Children, Healthy Minds: Creating a Brighter Future.

Children struggle with life today. Being children in the 21 century is both taxing and exciting and yet trying to cope with all of the technology and media that surrounds them. How do we as adults provide good models? Mindfulness, exercise, focus and attention, healthy living strategies need to play a role in shaping healthy children. Educators need to become well versed in strategies that both teach short and long term behaviors that will sustain healthy living and healthy minds. Children are the future and what kind of adult do we want running our countries and the world. The article provides many strategies for educators and parents to guide children in making choices that are both empowering and allow them the flexibility to be children.
Data in generative grammar: The stick and the carrot

Abstract This paper is intended to lay out for broader discussion some arguments for the importance of data in work in generative syntax. These are accepted by many linguists, but a significant number of others still seem reluctant to accept them. The basic claim is that it is no longer tenable for syntactic theories to be constructed on the evidence of a single person's judgements, and that real progress can only be made when syntacticians begin to think more carefully about the empirical basis of their work and apply the minimum standards we propose. We advance two groups of reasons for syntacticians to do this, negative and positive. The negative ‘stick’ group concerns the inadequacy of current practice. We argue that linguists are producing unsatisfactory work with these methods. Data quality is a limiting factor: a theory can only ever be as good as its data base. The positive ‘carrot’ group concerns the descriptive and theoretical advantages which become available with more empirically adequate data. We hope to tempt linguists to adopt new methods by showing them the insights which better data makes available.
The essence of language-integrated query

Language-integrated query is receiving renewed attention, in part because of its support through Microsoft’s LINQ framework. We present a theory of language-integrated query based on quotation and normalisation of quoted terms. Our technique supports abstraction over values and predicates, composition of queries, dynamic generation of queries, and queries with nested intermediate data. Higher-order features prove useful even for constructing first-order queries. We prove that normalisation always succeeds in translating any query of flat relation type to SQL. We present experimental results confirming our technique works, even in situations where Microsoft’s LINQ framework either fails to produce an SQL query or, in one case, produces an avalanche of SQL queries.
Terminology for interprofessional collaboration: Definition and current practice

Objectives: Interprofessional collaboration leads to an improvement in health care. This call for increased interprofessional collaboration has led to national and international recommendations for interprofessional learning and education. The GMA has taken up this challenge and has implemented a working group on “interprofessional education in the health professions” to address this topic. The terminology used to describe collaboration among the health professions seems to vary and does not reflect any clear consensus. The aim of this paper is to identify the different terms used to describe collaboration between health professions and to analyse their use in German journals. Methods: The terms frequently used to describe collaboration between health professionals were identified and defined. German medical journals were then pragmatically analyzed regarding the use of the terms interprof* and interdiszip*. Results: The German terms for interprofessional and interdisciplinary were not used consistently in the journals reviewed. Conclusion: There seems to be no agreement on the use of terms to describe the collaboration between health professions. Consistent terminology should be used as a basis for promoting collaboration and improving understanding among the parties involved.
Transfer time-aware workflow scheduling for multi-cloud environment

In the recent years, multi-cloud environment has attracted significant attention of the research community. Workflow scheduling in a multi-cloud environment is a challenging problem which is known to be NP-complete in nature. In this paper we propose an efficient workflow scheduling algorithm for multi-cloud environment which is based on transfer time consciousness. The proposed algorithm has two phases similar to Heterogeneous Earliest Finish time (HEFT) algorithm which was developed for multiprocessor system. The first phase calculates the B-Level priority of the tasks and second phase undergoes the virtual machines (VMs) selection based on the calculated B-level priority of the tasks. We simulate the proposed algorithm for standard scientific workflows and compare the simulated results with two existing workflow scheduling algorithms as per the proposed model. The results noticeably indicate that the proposed algorithm outperforms both the algorithms in terms of makespan and average cloud utilization.
Output dynamics in an endogenous growth model

The aim of this paper is to analyze whether endogenous growth RBC models are consistent with two stylized facts about U.S. output dynamics. First, GNP growth is positively correlated in the short run and it has a weak negative autocorrelation over longer horizons. Second, GNP appears to have an important trend-reverting component that has a hump-shaped MA representation. In particular, this article considers a stochastic version of Lucas\\\' (1988) model in the absence of externalities in discrete time with two modifications: agents derive utility not only from consumption but also from leisure and labor adjustment costs are included. Results reveal that combining the endogenous character of the engine of growth with labor adjustment costs may help solve the Cogley-Nason (1995) puzzle since it provides a stronger propagation mechanism which, in turn, improves the model\\\'s ability to generate realistic output dynamics.
Not All Links Are Created Equal: An Adaptive Embedding Approach for Social Personalized Ranking

With a large amount of complex network data available, most existing recommendation models consider exploiting rich user social relations for better interest targeting. In these approaches, the underlying assumption is that similar users in social networks would prefer similar items. However, in practical scenarios, social link may not be formed by common interest. For example, one general collected social network might be used for various specific recommendation scenarios. The problem of noisy social relations without interest relevance will arise to hurt the performance. Moreover, the sparsity problem of social network makes it much more challenging, due to the two-fold problem needed to be solved simultaneously, for effectively incorporating social information to benefit recommendation. To address this challenge, we propose an adaptive embedding approach to solve the both jointly for better recommendation in real world setting. Experiments conducted on real world datasets show that our approach outperforms current methods.
AutoFix: a hybrid tool for automatic logic rectification

We address the problem of rectifying an erroneous combinational circuit. Based on the symbolic binary decision diagram techniques, we consider the rectification process as a sequence of partial corrections. Each partial correction reduces the size of the input vector set that produces error responses. Compared with the existing approaches, this approach is more general, and thus, suitable for circuits with multiple errors and for the engineering change problem. Also, we derive the necessary and sufficient condition of general single-gate correction to improve the quality of rectification. To handle larger circuits, we develop a hybrid approach that makes use of the information of structural correspondence between specification and implementation. Experiments are performed on a suite of industrial examples as well as the entire set of ISCAS'85 benchmark circuits to demonstrate its effectiveness.
Software configuration—an NP-complete problem

Configuration Control File (CCF) production is very complex, thousands of code packages, data blocks and parameter values must be linked under many constraints including:*Common data and code less than 8192 bytes*Maximum of 5 registers per task*All systems data must have common capabilitiesNP-complete problems are commonly known as knapsack or bin packing problems. They have no known algorithm which solves them in a time period bounded by a polynominal function of the number of inputs. Rules-of-thumb, or heuristics are the only practical approach to their solution. CCF segmentation to meet constraints discussed above is an example of Expert System technology applied to a classic NP-complete problem.Heuristics developed with traditional data processing techniques initially performed satisfactorily. However, as program development proceeded, Central Processor Unit (CPU) time for (CCF) production became a concern, both from a commitment of CPU resources and lost productivity. Traditional techniques failed to improve the heuristics and the project began to slip. Projected time to produce the CCF for a fully developed program was totally unacceptable, and jeopardized the project.Clearly another approach was required. Because existing hueristics were based on a concept of rules, research indicated an expert system using rules and a knowledge based approach had the highest probability of success.The paper emphasizes the development process of a knowledge based system from the perspective of the responsible project manager. The methodology is also applicable to common business problems.
A simple miniaturized dual band notched UWB antenna

A compact dual band notched ultra wideband antenna is presented. The antenna is designed to notch two prominent wireless standards namely WLAN (5.15-5.85 GHz) and WiMax (3.3-3.85 GHz). The notched frequency bands are introduced by embedding two 90o clockwise rotated S-shaped stubs in the radiating patch. Insertion of two I-Shaped notches along both sides of the microstrip feed line in the ground plane enhanced the bandwidth up to 120%. The proposed antenna is compact having size 20×18 mm2 and covers the UWB frequency band from 2.8-10.6 GHz. The VSWR, gain and radiation pattern of the proposed antenna are simulated using computer simulation technology software. The antenna is also fabricated and results shows good acceptance with the simulated results.
Financing social ventures by crowdfunding

Studies on the profile of the social entrepreneurs that use crowdfunding (CF) for financing social projects are relatively rare, specifically in the context of Social Stock Exchange platforms. This research aims to understand the role played by social entrepreneurs’ personality traits on the choice between the traditional donation model and social CF to finance social projects. The particular case of the Portuguese Social Stock Exchange (PSSE) is presented and a quantitative and exploratory approach is used. The data were collected through a questionnaire that was emailed to non-governmental organizations in Portugal and founders of the projects listed on PSSE. Logistic regression is employed to predict the probability that a social entrepreneur would use PSSE rather than traditional financing. The predictor variables are based on the Big Five personality traits. Our investigation reveals that the conscientiousness personality trait is the only factor that might explain the use of the PSSE platform.
The Business Next Door : Click-Through Rate Modeling for Local Search

Computational advertising has received a tremendous amount of attention from the business and academic community recently. Great advances have been made in modeling click-through rates in well studied settings, such as, sponsored search and context match. However, local search has received relatively little attention. Geographic nature of local search and associated local browsing leads to interesting research challenges and opportunities. We consider a novel application of relational regression to local search. The approach allows us to explicitly control and represent geographic and category-based neighborhood constraints on the samples that result in superior click-through rate estimates. Our model allows us to estimate an interpretable inherent ‘quality’ of a business listing, which reveals interesting latent information about listings that is useful for further analysis.
Knowledge-based strategies and information system technologies: preliminary findings

Knowledge-Based (KB) strategies are being recognised as a vital factor of business strategy. Still, there is limited empirical research in this young academic field. This research intends to add to the limited empirical research in the area of Knowledge Management (KM) and Information Systems (IS) technologies. This research uses a recently proposed framework to analyse the relationship between six KB strategic dimensions, organisational culture, and IS technologies. The results indicated that two KB strategies had a positive association with a number of IS technologies, but not all types of IS technologies. Further, only one IS technology showed statistically significant association with one of the outcomes tested.
Reliable Estimation of Generalized Linear Mixed Models using Adaptive Quadrature

Generalized linear mixed models or multilevel regression models have become increasingly popular. Several methods have been proposed for estimating such models. However, to date there is no single method that can be assumed to work well in all circumstances in terms of both parameter recovery and computational efficiency. Stata's xt commands for two-level generalized linear mixed models (e.g., xtlogit) employ Gauss–Hermite quadrature to evaluate and maximize the marginal log likelihood. The method generally works very well, and often better than common contenders such as MQL and PQL, but there are cases where quadrature performs poorly. Adaptive quadrature has been suggested to overcome these problems in the two-level case. We have recently implemented a multilevel versionofthismethodin gllamm, a program that fits a large class of multilevel latent variable models including multilevel generalized linear mixed models. As far as we know, this is the first time that adaptive quadrature has been proposed for multilevel models. We show that adaptive quadrature works well in problems where ordinary quadrature fails. Furthermore, even when ordinary quadrature works, adaptive quadrature is often computationally more efficient since it requires fewer quadrature points to achieve the same precision.
