Current Practice in Management of Acute Coronary Syndrome in Tertiary Iraqi Cardiac Centers

ackground There is continued debate as to whether a routine, early invasive strategy is superior to a conservative strategy for the management of acute coronary syndromes. Aim of the study: To verify current practice in the setting of management of acute coronary syndromes in tertiary cardiac centers in Iraq. Patients and methods Four hundred (400) patients were included in this study from 1 of January 2012 to 1 of January 2013from two tertiary Iraqi cardiac centers. Three hundred (300) patients from Ibn Albitar hospital and One hundred (100) patients from Iraqi center for heart disease refered to them as group (A) and group (B) respectively. Results & discussion Mean age for all patients was54.6±9.9 year. In group A there was 208 male patients (69.3%), 92 female patients (30.6%), in group B there was 65 male patients (65%), 25 female patients (25%). Low score (using thrombolysis in myocardial infarction score) found in 166(41.6%), intermediate score in 221 (55.3%), high in 13 (3.3%), no patients with high score was found in group B, mean TIMI score in group A was 1.61±0.5, in group B was 1.60±0.5 (P value NS). In group A UA found in 249 (83%), STEMI in 23 (7.7%), NSTEMI in 28 (9.3%). In group B UA in 79 (79%), STEMI in16 (16%), NSTEMI in 5 (5%) (Pvalue0.02). Smoking is prevalent more in group A (186 patients (62%) versus 43 patients (34%) in group B), while diabetes mellitus and family history of premature coronary artery were more prevalent in group B (Pvalue0.03). All patients in group A with low score were treated medically while in group B with low score treated invasively. Invasive approach was more in group B compared with group A in intermerdiate risk score. Normal coronaries were found in (3.3%) in group A versus (6.8%) in group B. Percutaneous coronary intervention was applied in (66.6%) in group A versus (50%)in group B, surgery used in (23.3%)in group A versus (28.3%)in group B, medical treatment in (10%) in group A versus (21.6%) in group B. There were no statistical difference between both groups regarding duration of admission to hospital and mortality. Conclusion Management of acute coronary syndromes was the same between tertiary cardiac centers and it is progressing significantly in our country.
Research on Library and Information Science in Spain: diagnosis 2020

Spanish research in Documentation (or Library and Information Science, LIS) rose to prominence in the 1980s, in parallel with the creation of university programmes in LIS, and activity in this field continued to increase significantly until the year 2000. During this period, research in Documentation was oriented towards dissemination rather than innovation, its international impact was low, and it suffered from limited financial and human resources and a lack of methodological quality. In the first 20 years of the 21st century, research in this field has experienced an extraordinary level of growth and diversification, with the result that many of the problems mentioned above have been resolved. This article presents a general overview of Documentation research in Spain over the last 20 years based on an analysis of five fundamental aspects: publications (articles and monographs), topics and methodologies, scientific journals, research projects, and doctoral theses. General descriptive data from public statistical sources are offered on each of these aspects, together with observations drawn from a bibliographic review. Our conclusion is that the evolution of Spanish research in Documentation over the last 20 years has been very positive, due to a quantitative increase in activity (publications, theses, research projects, etc.) and a qualitative improvement in the use of research methods and techniques, as well as a diversification of research topics. However, there is room for improvement in the area of internationalisation (collaboration with foreign authors) and the presentation of international projects. There is also a risk that retirement of researchers and the absence of generational renewal of staff, especially at universities, may slow down this growth.
ESTIMATION OF A CONVEX DENSITY AT THE ORIGIN: BACK TO HAMPEL’S BIRDS PROBLEM

Abstract: Motivated by Hampel’s birds migration problem, Groeneboom, Jongbloed, and Wellner (2001b) established the asymptotic distribution theory for the nonparametric Least Squares and Maximum Likelihood estimators of a convex and decreasing density at a fixed point t0 > 0. However, estimation of the distribution function of the birds resting time involves the value of the first derivative of the estimators at 0, at which they are not consistent. In this paper, we focus on the Least Squares estimator and show that it is possible, following the idea of Kulikov and Lopuhaä (2005) for monotone estimation, to construct consistent estimators as long as we ‘stay away’ from 0. Moreover, we derive their exact asymptotic distributions.
Complementor dedication in platform ecosystems: rule adequacy and the moderating role of flexible and benevolent practices

ABSTRACT Dedicated complementors are devoted, faithful, and willing to invest in their partnership with a platform owner. Since such complementors promise continuous value co-creation, complementor dedication is an essential objective of platform governance. However, as dedicated complementors also increase their vulnerability vis-à-vis the platform owner, platform governance needs to strike a balance between satisfying global ecosystem needs and the local partnership needs. To understand this challenge better, our study develops six hypotheses on how two fundamental governance mechanisms – i.e., rules and the way in which these rules are practised – independently and symbiotically drive complementor dedication. We test these hypotheses using survey data from 181 complementors. Our findings show that complementors become more dedicated to a platform owner, the more adequate they perceive the rules to be. Furthermore, our findings suggest two sensible strategies to actualise the potential of adequate rules. Platform owners should either refrain entirely from practising rules with situational flexibility and benevolence, thereby achieving moderate complementor dedication. Alternatively, they should practice rules with both flexibility and benevolence at the same time, thereby maximising complementor dedication. Our findings contribute to the literature on platform governance and broader governance literature.
The welfare and ethics of research involving wild animals: A primer

Wild animals are used in scientific research in a wide variety of contexts both in situ and ex situ. Guidelines for best practice, where they exist, are not always clearly linked to animal welfare and may instead have their origins in practicality. This is complicated by a lack of clarity about indicators of welfare for wild animals, and to what extent a researcher should intervene in cases of compromised welfare. This Primer highlights and discusses the broad topic of wild animal welfare and the ethics of using wild animals in scientific research, both in the wild and in controlled conditions. Throughout, we discuss issues associated with the capture, handling, housing and experimental approaches for species occupying varied habitats, in both vertebrates and invertebrates (principally insects, crustaceans and molluscs). We highlight where data on the impacts of wild animal research are lacking and provide suggestive guidance to help direct, prepare and mitigate potential welfare issues, including the consideration of end‐points and the ethical framework around euthanasia. We conclude with a series of recommendations for researchers to implement from the design stage of any study that uses animals, right through to publication, and discuss the role of journals in promoting better reporting of wild animal studies, ultimately to the benefit of wild animal welfare.

Ultrasonic Velocity and allied parameters of drug Colimax in aqueous 1-propanol at 298.15K

Ultrasonic velocity (U) and density (ρ) have been measured at 298.15K for drug colimax in binary mixture of 1-propanol(PrOH)+water(H2O). Various acoustical parameters such as acoustical impedance (Z), adiabatic compressibility (β), intermolecular free length (Lf), relative association (R.A.), molar volume (Vm) and molar sound velocity (Rm) have been calculated from ultrasonic velocity & density data. The results have been discussed from the view point of drugsolvent and intermolecular interactions.
Decision support for the selection of water release strategies at open-air irrigation reservoirs

Water earmarked for irrigation purposes in the agricultural sector is typically stored in openair reservoirs. The availability of irrigation water greatly impacts the profitability of this sector and this availability is largely determined by prudent decisions related to water release strategies at open-air reservoirs. The release strategy for an open-air irrigation reservoir is typically decided upon by a board of management at the start of the hydrological year. The selection of such a strategy is difficult, since the objectives which should be pursued are not generally agreed upon and unpredictable weather patterns cause reservoir inflows to vary substantially between hydrological years. A mathematical model is proposed in this paper which may form the basis of a decision support system for the selection of a beneficial water release strategy. Based on historical data, the proposed model generates a probability distribution of the reservoir volume at the end of a hydrological year for a given initial water release strategy and stochastically simulated reservoir inflows. The initial strategy is dictated by irrigation demands and reservoir sluice parameters. This strategy is then adjusted iteratively, with the aim of centring the hydrological year end volume distribution on some target value. Adjustments are made according to user-specified weight factors, which represent the demand satisfaction importance of the various decision periods. The repeatability of a given water release strategy is taken to depend on an estimate of the most likely reservoir volume at the end of the hydrological year as a result of this strategy. The probability of water shortage for a given transition volume may be determined using this model by equating the start and end volumes for simulated hydrological years. This information allows for the computation of acceptable tradeoff decisions between the fulfilment of the current hydrological year’s demand and the future repeatability of a release strategy.
Association Between Expression of Interleukin-32 Gene and Various Helicobacter pylori Virulence Factors in Human Infected Gastric Biopsy

Helicobacter pylori (H. pylori) is a spiral bacterium that infects the human gastric mucosa. Various clinical aspects of the infection may mirror distinctive forms of cytokine expression. It correlates with immune cell penetration to the gastric mucosa with numerous cytokines production and gastric inflammation. IL-1 and IL-8 directly contribute to H. pylori effected gastritis. IL-32 is a pro-inflammatory cytokine categorized by the training of Immune cell activation, which has a vital role in human immunity. H. pylori virulence and danger factors are critical in gastritis, such as the outer inflammatory protein (OipA) and the cytotoxin associated gene a (cagA). We aimed to study the IL-32 mRNA expression in H. pylori-positive and negative patients as well as its relation with bacterial cagA, oipA, and severity of gastritis. Endoscopic biopsies were taken from the antrum of 60 H. pylori-infected patients and 62 uninfected individuals. Mucosal IL-32 mRNA expression was assessed by real-time PCR. With PCR, the H. pylori virulence factors were evaluated. Showed that the mRNA expression of IL-32 levels was significantly lower in biopsies of H. pylori-uninfected patients compared to positive individuals (P=0.01). A straight communication between virulence factor up, cagA, and heightening in IL-32 mRNA expression (P<0.001) was observed. Furthermore. IL-32 mRNA expression levels were approximately equal in both chronic and active gastritis (P=0.1). IL-32 may have a critical role in different situations like inflammation and the severity of inflammatory changes in the gastric mucosa.
Attitude Towards Infant Feeding Among Health Workers in Calabar, Nigeria

Background: Effective practice of recommended infant feeding methods is key to child survival strategy in sub-Saharan Africa. Attitude towards infant feeding has been shown to be a significant determinant of practice. For health workers, attitude may determine the propensity to counsel mothers towards adoption and adherence to recommended infant feeding practices. This study aimed at assessing health workers’ attitude towards infant feeding. Methods: This was a cross-sectional descriptive study carried out in April 2019. Leslie Kish formula was used to recruit 225 health workers in Calabar to participate in the study. Ethical approval was obtained from the Cross River State Research and Health Ethics Committee. A validated self-administered IOWA infant feeding attitude scale was utilized in this study. Using the scale, attitude was categorized as positive for breastfeeding, neutral, and positive for formula feeding. Data was analysed using SPSS version 21.0, and p-value was set at 0.05. Result: Two hundred and twenty-five respondents completed the questionnaire. Female: male ratio was 1:0.24, the commonest age group (43.1%) was 31 to 40 years old, and 60% of respondents were nurses. Most respondents (52.9%) had neutral attitude, while 44.0% had positive attitude for breastfeeding, and 3.1% had positive attitude towards formula feeding. Age group, religion, profession, and ethnicity did not significantly influence attitude towards breastfeeding (p>0.05). Conclusion: Neutral attitude towards breastfeeding was common among health workers. This has implications for successful implementation of the recommended breastfeeding initiative towards improvement in child survival especially in resource-poor settings. Regular re-training of health workers is needed, especially through continuing educational effort by the various health professional bodies.
Multimodal learning analytics for game-based learning

A distinctive feature of game-based learning environments is their capacity to create learning experiences that are both effective and engaging. Recent advances in sensor-based technologies such as facial expression analysis and gaze tracking have introduced the opportunity to leverage multimodal data streams for learning analytics. Learning analytics informed by multimodal data captured during students? interactions with game-based learning environments hold significant promise for developing a deeper understanding of game-based learning, designing game-based learning environments to detect maladaptive behaviors and informing adaptive scaffolding to support individualized learning. This paper introduces a multimodal learning analytics approach that incorporates student gameplay, eye tracking and facial expression data to predict student posttest performance and interest after interacting with a game-based learning environment, Crystal Island. We investigated the degree to which separate and combined modalities (ie, gameplay, facial expressions of emotions and eye gaze) captured from students (n = 65) were predictive of student posttest performance and interest after interacting with Crystal Island. Results indicate that when predicting student posttest performance and interest, models utilizing multimodal data either perform equally well or outperform models utilizing unimodal data. We discuss the synergistic effects of combining modalities for predicting both student interest and posttest performance. The findings suggest that multimodal learning analytics can accurately predict students? posttest performance and interest during game-based learning and hold significant potential for guiding real-time adaptive scaffolding.
Can Private Equity Funds Act as Strategic Buyers? Evidence from Buy-and-Build Strategies

By holding assets longer and increasingly focusing on growth strategies private equity firms enter the territory of strategic buyers. In one such strategy, a private equity firm buys a company and then builds on that â€œplatformâ€ through add-on acquisitions. We ask whether such serial (buy-and-build) acquisition strategies deliver operating synergies, as expected from strategic buyers, or rather are a form of â€œwindow-dressing. â€ We collect a sample of buy-and-build strategies from seven major European markets and find that the profitability of these strategies improves more than that of the comparable strategies, constructed by us from stand-alone companies. We analyze a number of operating outcomes across various strategy sub-types and confirm that these operational improvements are consistent with the synergy interpretation.
ASAP: a dataset of aligned scores and performances for piano transcription

In this paper we present Aligned Scores and Performances (ASAP): a new dataset of 222 digital musical scores aligned with 1068 performances (more than 92 hours) of Western classical piano music. The scores are provided as paired MusicXML files and quantized MIDI files, and the performances as paired MIDI files and partially as audio recordings. Scores and performances are aligned with downbeat, beat, time signature, and key signature annotations. ASAP has been obtained thanks to a new annotation workflow that combines score analysis and alignment algorithms, with the goal of reducing the time for manual annotation. The dataset itself is, to our knowledge, the largest that includes an alignment of music scores to MIDI and audio performance data. As such, it is a useful resource for a wide variety of MIR applications, from those that target the complete audio-to-score Automatic Music Transcription task, to others that target more specific aspects (e.g., key signature estimation and beat or downbeat tracking from both MIDI and audio representations).
Tropical forest cover dynamics and carbon emissions – contribution of remote sensing and data mining techniques

: The absence of accurate and precise estimates of tropical deforestation and forest degradation, and the resultant changes in carbon stock densities contribute one of the largest sources of error in the global carbon budget. Various studies over the decades points out that the emissions from tropical forests ranges from 0.42–2.00 Pg C year –1 . The major reasons for such level of uncertainty arise from the unreliability of national and regional scale deforestation and forest degradation rates, unavailability of national long-term plot level in situ data for most of the developing countries and lack of computational power to extract patterns from large extent of spatial variability in carbon storage. The absence of unified definition for forests across countries, and disparity in sampling schemes also contribute to the uncertainty in the estimates of carbon stocks and emissions. These key scientific challenges must be accounted to enhance our understanding of the climate-carbon feedbacks and to mitigate climate change through new and existing policies such as Reducing Emissions from Deforestation and Degradation (REDD+). Here we review the estimates of carbon emissions from tropical forests, and the developments in the quantification of carbon stocks in tropical forests with an emphasis on how remote sensing technology and data mining techniques contributed in reducing the uncertainty in the global carbon emissions over the years.
Bayesian Model Averaging for Spatial Autoregressive Models Based on Convex Combinations of Different Types of Connectivity Matrices

Abstract There is a great deal of literature regarding use of nongeographically based connectivity matrices or combinations of geographic and non-geographic structures in spatial econometric models. We focus on convex combinations of weight matrices that result in a single weight matrix reflecting multiple types of connectivity, where coefficients from the convex combination can be used for inference regarding the relative importance of each type of connectivity in the global cross-sectional dependence scheme. We tackle the question of model uncertainty regarding selection of the best convex combination by Bayesian model averaging. We use Metropolis–Hastings guided Monte Carlo integration during MCMC estimation of the models to produce log-marginal likelihoods and associated posterior model probabilities. We focus on MCMC estimation, computation of posterior model probabilities, model averaged estimates of the parameters, scalar summary measures of the non-linear partial derivative impacts, and their associated empirical measures of dispersion.
Suppression of Fungal Pathogens and Growth Promotion of Carnation (Dianthus Caryophyllus CV. Sunrise) by Fluorescent Psevdomonas

An attempts were made to characterize rhizobacteria Pseudomonas species for direct and indirect PGP activities so as to select and develop more efficient indigenous POPR strains specific to soil type and to plant type. Twenty bacterial isolates were isolated from rhizosphere of carnation, out of which nine isolates were screened out for the production of multiple PGP activities and disease suppressing activities. Maximum isolates have shown the production of siderophore, ammonia, phosphate solubilization, proteolytic activities and significant production of plant growth regulators i.e., auxins, gibberellins and cytokinin. By RAPD profile strains were found different among themselves. Among them two strains i.e., MC, PS-II, were found to be best for the production of PGP activities and they were selected for field experiment. Significant increase in various growth parameters of plant were recorded.
Non-local Impacts on Eddy-Covariance Air–Lake CO2 Fluxes

Inland freshwater bodies form the largest natural source of carbon to the atmosphere. To study this contribution to the atmospheric carbon cycle, eddy-covariance flux measurements at lake sites have become increasingly popular. The eddy-covariance method is derived for solely local processes from the surface (lake). Non-local processes, such as entrainment or advection, would add erroneous contributions to the eddy-covariance flux estimations. Here, we use four years of eddy-covariance measurements of carbon dioxide from Lake Erken, a freshwater lake in mid-Sweden. When the lake is covered with ice, unexpected lake fluxes were still observed. A statistical approach using only surface-layer data reveals that nonlocal processes produce these erroneous fluxes. The occurrence and strength of non-local processes depend on a combination of wind speed and distance between the instrumented tower and upwind shore (fetch), which we here define as the time over water. The greater the wind speed and the shorter the fetch, the higher the contribution of non-local processes to the eddy-covariance fluxes. A correction approach for the measured scalar fluxes due to the non-local processes is proposed and also applied to open-water time periods. The gas transfer velocity determined from the corrected fluxes is close to commonly used wind-speed based parametrizations.
