P1780 Left ventricular golbal longitudinal strain in acute myocardial infarction and incidence of in hospital heart failure

The occurrence of in-hospital heart failure in the acute phase of myocardial infarction carries an ominous prognosis and is often preceded by abrupt loss of functioning myocardium. However ,In hospital heart failure may occur in patients with apparently only minor myocardial injury and preserved or only moderately reduced left ventricular ejection fraction and still carries a significantly increased risk of adverse outcome. In patients with clinical symptoms of heart failure despite preserved left ventricular ejection fraction(heart failure with preserved ejection fraction), abnormalities in longitudinal myocardial mechanics have been reported suggesting that the discrepancy between near normal left ventricular ejection fraction and clinical symptoms may be partially explained by theses indices. Evaluation of the role of global longitudinal strain in prediction of the occurrence of in hospital heart failure in patients presenting with acute myocardial infarction particularly in patients with normal ,or moderately impaired ejection fraction. forty patients with first attack of acute myocardial infarction were ranked according to killip class during their hospital admission and course. The patients were divided into two groups: Group 1: patients having in-hospital heart failure (killip class > 1). Group2: Patients not having in–hospital heart failure (killip class = 1). Echocardiogaraphic examination was done for them including global longitudinal strain within 72 hours after successful reperfusion . Comparison of different echocardiographic parameters between the two groups was done. Patients with mildly impaired ejection fraction (Ejection fraction > 40%) were studied for echocardiographic parameters correlated significantly with the occurrence of in-hospital heart failure . Patients with in-hospital heart failure had significantly impaired global longitudinal strain(-8.63%+1.57% vs -12.41%+1.31%, p = 0.000), lower left ventricular ejection fraction (34.17%+8.17% vs 42.92 %+7.98%,p < 0.001) and higher wall motion score index (1.57 + 0.32 vs 1.31 +0.24 ,p < 0.006). In patients with left ventricular ejection fraction >40% experienced in-hospital heart failure also exhibited significantly impaired global longitudinal strain p= 0.035 . Global longitudinal strain can offer accurate, feasible, and non invasive predictor of hemodynamic deterioration in patients with myocardial infarction. Global longitudinal strain was superior to left ventricular ejection fraction , wall motion score index in evaluation of myocardial dysfunction specially in those with preserved left ventricular ejection fraction(EF > 40%). Global longitudinal strain was also superior to left ventricular ejection fraction , wall motion score index in detection of patients with Killip class II ( those without overt heart failure ,and who can be easily missed).
Fine-scale variables associated with the presence of native forbs in natural temperate grassland

24 Broad-scale threats to floristic diversity in native temperate grasslands are well-documented and 25 include elevated soil nutrients, changes in disturbance regimes and exotic species. However, fine-scale 26 variables associated with the presence of native forbs, such as gap size and biomass cover, have 27 received relatively little attention. We conducted a case-control study to determine the relative 28 influence of physical structural dimensions and other fine-scale variables associated with the presence 29 of native forbs in a modified temperate grassland previously used for domestic grazing. We matched 30 145 case plots centred on 27 different species of native forb with 290 control plots not centred on a 31 native forb. For each percentage increase in ground litter cover, dead biomass cover, grass cover or 32 exotic forb cover, or the area of bare
New venture evolution of migrants under institutional voids: Lessons from Shonga Farms in Nigeria

This article inductively builds theory on how transaction costs may be alleviated and institutional voids bridged in developing economies, based on the case study of successful migrant entrepreneurial involvement in Nigerian agriculture: Shonga Farms. We argue that the iterative process of building conditions of trust through long-term commitment, involvement of regional government, appropriate modes of financial contracts and the gradual transitioning of controlling interests to private actors are factors of success. We draw additional lessons by contrasting our case study with other similar migrant schemes that have failed.
Desempenho Econômico-Financeiro de Operadoras de Planos de Saúde Suplementar

The federal regulation of the Brazilian sector of Supplementary Health has been stimulating competitiveness between companies specialised in this area, who seek a maximization of results, in addition to meeting the requirements of said regulation. In this context, the knowledge of the economic-financial performance becomes very important, since it assists and serves as assessment of organizational decisions. So this article has as its research question: how is the economic-financial performance of health private plan operators going and what have been the differences between them over the years, considering the following indicators: Return on Total Assets, Operational Return on Total Assets, Return on Equity, Current Liquidity, Short-Term Debt and Loss? The overall objective is to identify the economic-financial performance of health private plan companies, as well as comparing its results inn the years 2008 to 2012. For this, a quantitative descriptive and documentary research was carried out, building a database with the accounting information from the companies to measure the performance through seven economic-financial indexes, and for data analysis and interpretation, univariate statistics and the Median Test were done. The comparison of the median values of the indexes over the years showed, as a result, statistically significant differences in the companies’ economic-financial performances, when measured by the Return on Total Assets, Short-term Debt and Loss ratios. The results suggest further researches that relate performance to the structuring of the sector. , including the companies’ management ways.
Maternal and fetal outcome of placenta previa in a tertiary care institute: a prospective two year study

Introduction: Placenta previa (PP) is an important cause of maternal and fetal morbidity and mortality worldwide but there is not much data from the developing countries about maternal and fetal outcome1. Aim: To determine the incidence and maternal and fetal outcomes among women with placenta previa (PP). Material and Methods: This is a prospective observational study carried out at Sri Ramachandra Medical College, Sri Ramachandra University Porur, Chennai, in the Department of Obstetrics and Gynaecology between July 1st 2012 to July 31st 2014. Results: Total number of patients delivered during this period were 8694 and out of which 174 patients were diagnosed with placenta previa, so the incidence is 2%. Of women with placenta previa, 3.44%(n=6) had placenta accreta. Incidence of placenta previa was the highest in the maternal age group 20-29 years i.e. 72.9%, Perinatal morbidity was studied as the percentage of babies requiring resuscitation and NICU admission which was 37.35%(n=65). Caesarean hysterectomy was performed in 1.14% (n=2) cases, there were 1.72 %(n=3) perinatal deaths. Keywords: Placenta previa, Placenta accreta, Postpartum hemorrhage
Single‐Cell RNA Sequencing of Calvarial and Long‐Bone Endocortical Cells

Single‐cell RNA sequencing (scRNA‐Seq) is emerging as a powerful technology to examine transcriptomes of individual cells. We determined whether scRNA‐Seq could be used to detect the effect of environmental and pharmacologic perturbations on osteoblasts. We began with a commonly used in vitro system in which freshly isolated neonatal mouse calvarial cells are expanded and induced to produce a mineralized matrix. We used scRNA‐Seq to compare the relative cell type abundances and the transcriptomes of freshly isolated cells to those that had been cultured for 12 days in vitro. We observed that the percentage of macrophage‐like cells increased from 6% in freshly isolated calvarial cells to 34% in cultured cells. We also found that Bglap transcripts were abundant in freshly isolated osteoblasts but nearly undetectable in the cultured calvarial cells. Thus, scRNA‐Seq revealed significant differences between heterogeneity of cells in vivo and in vitro. We next performed scRNA‐Seq on freshly recovered long bone endocortical cells from mice that received either vehicle or sclerostin‐neutralizing antibody for 1 week. We were unable to detect significant changes in bone anabolism–associated transcripts in immature and mature osteoblasts recovered from mice treated with sclerostin‐neutralizing antibody; this might be a consequence of being underpowered to detect modest changes in gene expression, because only 7% of the sequenced endocortical cells were osteoblasts and a limited portion of their transcriptomes were sampled. We conclude that scRNA‐Seq can detect changes in cell abundance, identity, and gene expression in skeletally derived cells. In order to detect modest changes in osteoblast gene expression at the single‐cell level in the appendicular skeleton, larger numbers of osteoblasts from endocortical bone are required. © 2020 American Society for Bone and Mineral Research.
Characteristics, Engagement and Academic Performance of First-Year Nursing Students in Selected Ontario Universities

With an aging population nationally, nursing programs have struggled to meet the demand for nurses in our healthcare system. Student attrition remains high at 28% within the first two years of the Baccalaureate nursing programs. In order to meet healthcare system demand, nursing programs need to ensure that students persist, graduate, and are academically successful on the national examination. As a first step in student success, one needs to identify effective educational practices in first-year nursing programs that are associated with student engagement within the Canadian context. Extensive research in the U.S. has examined educational practices and student engagement. However, few national or international studies examined nursing student characteristics and engagement and student success. This study examined the extent to which first-year nursing students are engaged in effective educational practices and any relationships between student demographic, external, academic, social, and institutional variables, and student engagement. A descriptive correlational design was used to conduct a secondary analysis of pre-existing 2008 National Survey of Student Engagement (NSSE) data from nursing students in 13 Ontario Universities. Descriptive statistics were computed to examine student characteristics and the distribution of NSSE benchmark
Influence of Municipalities on LAG's Effectiveness in Attracting Project Subsidies in Croatia

Local Action Groups LAGs are tri-sectoral bodies in which the economic and civil sectors in partnership with the public sector use EU policy funds for rural development. In such a decentralized approach to communityled local development, there is a risk of excessive municipal interference and principles of bottom-up development can be compromised. The basic assumption by which the leading public sector is trying to justify itself as having a better administrative capacity that can help LAGs to attract and absorb subsidies is statistically tested in this paper. Example of Croatia has shown that “municipalization” of local partnerships have no justifications, as increasing the share of public partners in the membership structure reduces LAG effectiveness in attracting project subsidies, and in the same time municipalities that prove stronger absorptive capacity through larger share of EU funds in their budget, show no positive influence transferred to LAGs in which they are members.
Epidemiology of burns in teaching hospital of Northern India

Background: There is no information on the pattern of outcomes among burn patients in relation to clinical aspects in India. Hence, the present study was undertaken in a burn unit to determine selected epidemiological variables, assess the clinical aspects (etiology, extent and anatomical location) and finally to analyze the outcomes in cases of burn injury. Materials and Methods: This prospective study was undertaken to analyze the patients admitted to the Burn Unit of Government Medical college Srinagar. The study was carried over a period 2 years from January 2013 to December 2014. Various variables including age and sex distribution, nature of burn injuries, Anatomical location, percentage of total body surface area burnt, depth of burns, Survival of expired patients and mortality were recorded and analyzed. Results: Highest incidence of burns was in the age group between 21 and 40 years; 61% patients were females and 39% were males; majority of our patients had burns in the range of 20 to 40% TBSA (total body surface area); mortality rate in our study was 36.82%; most common site of the burn injury was upper limb(30.19%);among patients who died those with TBSA burn of >60%, 41 to 60% and 31 to 40% succumbed within three, six and nine days respectively. Age ranged from 6 months to 93 years. Mean age of the patients was 31 years. Eighty percent patients belonged to rural areas and 20% belonged to Urban locality. Conclusion: People with low educational qualification should be taught about the proper and safe usage of modern appliances based on electricity, LPG or kerosene. People with psychiatric problems or low intelligence quotient (I.Q) should be helped by their care takers in avoiding the burn injuries and also devices with alarms should be used in their households. Fuel or electric devices should be checked by a trained person regularly (e.g once in month) to avoid usage of faulty devices.
SURVEI DAN EDUKASI PENGGUNAAN PESTISIDA DI RUMAH TANGGA DAN DAMPAKNYA TERHADAP KESEHATAN PADA MASYARAKAT DI NAGARI PANASAHAN KOTA PAINAN

Various pesticides are widely used in households to control animals and pests. Pesticides consist of chemicals known to be harmful to health, so their use must be regulated in a certain way to avoid acute and chronic toxicity to humans. The purpose of this activity is to conduct a survey regarding the knowledge and behavior of a community in Nagari Panasahan, Painan, regarding the use of pesticides and their impact on health and to conduct education on how to properly use pesticides. Assessment of participant knowledge and behavior regarding pesticide use was carried out using a questionnaire with 28 questions. A total of 35 participants took part in the educational program. The questionnaire response analysis showed that most of the participants were housewives, had a primary-secondary education, had limited income, used more than one type of pesticide to control nuisance animals, and had limited knowledge about the chronic toxicity pesticides and about how to protect health. Environmental health experts provide educational materials on pesticides, their effects on health and prevention efforts, followed by interactive discussions. Further evaluation is needed to determine whether the program is successful in modifying pesticide use in this community.
Assessing heavy metal pollution and potential ecological risk of 
tea plantation soils

Accumulation of heavy metals in agricultural soils tends to increase crop uptake of heavy metals, and can adversely impact human health through food chains. This study assessed the heavy metal pollution status and the potential ecological risk of tea plantation soils in southern Shaanxi Province, China. A total of 330 topsoil samples were collected to analyze the concentrations of seven heavy metals (Pb, Zn, Cu, Cr, Hg, As and Cd) and the pH level. The Hakanson potential ecological risk index was used based on the background levels of soil heavy metals in Shaanxi. Results showed that the averaged concentrations of soil Pb, Zn, Cu, Cr, Hg, As, and Cd were 10.0, 87.6, 16.4, 12.4, 0.2, 6.9 and 0.1 mg/kg, respectively. Cd and Hg concentrations exceeded level II of China’s Soil Environment Quality Standard (GB 15618–2009) in 9.3% and 7.0% of the total samples, respectively. The coefficient of variation ranged from 29.2% to 52.2% for different elements, and was 49.3% for Cd and 48.6% for Hg. The averaged comprehensive potential ecological risk index was 95.4, and the overall potential ecological risk was low, with 82.4% of the total samples at a low level of potential ecological risk. Cd and Hg contributed most to the potential ecological risk (35.5% and 46.5%, respectively), and the risks associated with other elements were relatively minor. This study suggested that soil Cd and Hg pollution should be controlled to ensure the safe production of tea in the study area.

The development of innovative patient-specific surgical guides

Additive Manufacturing (AM) is widely gaining popularity as an alternative manufacturing technique for complex and customized parts. AM materials are used for various medical applications in both metal and polymer options. Adenosine Triphosphate (ATP) bioluminescence technology is a rapid, user-friendly method of quantifying surface cleanliness and was used in this study to gather quantitative data on levels of contamination on AM materials at three different stage processes: post build, post cleaning and post sterilization. The surface cleanliness of eleven AM materials, three metals and eight polymers, was tested. ATP bioluminescence provided the sensitivity to evaluate different material surface characteristics, and specifically the impact of surface finishing techniques on overall cleanliness.
Superior Mesenteric Artery Syndrome: A Worldwide Descriptive Study with Literature Review

Background: Superior mesenteric artery syndrome is best described as compression of the third part of duodenum by the superior mesenteric artery, resulting in obstruction. This rare condition has been studied for decades yet remains obscure. This study aimed to analyze different clinical presentations, diagnostic modalities, treatment approaches and outcomes of this condition. Methods: Thirty-five superior mesenteric artery syndrome cases were collected retrospectively from a Facebook group called “Superior Mesenteric Artery Syndrome Awareness & Support”. A questionnaire was designed using Google Forms to obtain the demographics, presenting symptoms, risk factors and co-morbidities, investigations, means of treatment and the outcomes. Data was entered into Microsoft Office Excel for statistical analysis. Results: The median age at diagnosis was 22 years. The median body mass index was 20.8 kg/m 2 . The median time interval from symptom onset to initial diagnosis was 22 months. The major presenting symptoms were abdominal pain (82.9%), nausea (77.1%), and vomiting (65.7%). Abdominal computed tomography scan with contrast (82.9%) was commonly used for confirmation of diagnosis. Thirteen cases (37.1%) were congenital. Thirty patients (85.7%) had received treatment. The overall management success was only 13.3%. Surgical management (34.3%) was the most commonly used regimen. Conclusion: Diagnosis of superior mesenteric artery syndrome is established after a thorough assessment of the clinical presentations and confirmed with suitable imaging modalities. The choice of treatment should be dependent on the causes and severity as different patients respond differently to therapy. Recurrence is possible in all patients, and a long-term follow up is thus required.
Is boredom proneness related to social media overload and fatigue? A stress-strain-outcome approach

PurposeSocial media overload and fatigue have become common phenomena that are negatively affecting people's well-being and productivity. It is, therefore, important to understand the causes of social media overload and fatigue. One of the reasons why many people engage with social media is to avoid boredom. Thus, the purpose of this paper is to investigate how boredom proneness relates to social media overload and fatigue.Design/methodology/approachBuilding on the stress–strain–outcome framework, this paper tests a model hypothesizing the relationships between a social media user's boredom proneness, information and communication overload, and social media fatigue. The study tests the model by collecting data from 286 social media users.FindingsThe results suggest a strong association between boredom proneness and both information and communication overload, which, in turn, are strongly associated with social media fatigue. In addition, social media usage was found to amplify the effects of information overload on social media fatigue, but, unexpectedly, attenuates the effects of communication overload.Originality/valuePrior research has largely overlooked the connection between boredom and problematic social media use. The present study addresses this important gap by developing and testing a research model relating boredom proneness to social media overload and fatigue.
Audit committee characteristics and tax aggressiveness

Purpose This study aims to analyze the relationship between a company’s use of aggressive tax planning and several audit committee members’ characteristics, namely, independence, expertise, diligence and gender diversity. Design/methodology/approach This paper is an empirical research using archival data from 289 Canadian listed companies for the 2011-2015 period. Findings The authors find that measures of expertise and diligence are significantly related to tax aggressiveness. Financial expertise and tenure on the audit committee play an important role in constraining tax aggressiveness, as does having a larger audit committee. Research limitations/implications One limitation – and an area for future research – is that the effects of the audit committee members’ relationships with managers of the firms were not investigated. Practical implications Knowledge of audit committee characteristics may send a signal to shareholders, investors and tax agencies regarding the company’s potential risk with respect to aggressive tax planning. The analysis provides useful insights for board governance committees when determining the profile of persons to nominate for board positions and committees. In discussing tax-risk management, the study may heighten audit committee members’ awareness of their role in this respect. Originality/value This study’s results indicate that even in a setting where incentives for firms to be tax-aggressive is low compared to high-tax rate countries, there is variability in firms’ tax aggressiveness. This situation allows us to find audit committee characteristics that are effective in decreasing tax aggressiveness.
