Full Text Available Background: Bank employees, with their resources and infrastructure, are ideal for increasing awareness and initiating preventive activities for the control of coronary heart disease (CHD. However, there are no reliable estimates of CHD risk factor burden, or of its awareness and treatment status among bank employees. The study intends to evaluate the prevalence of risk factors of CHD among bank employees of Belgaum city. Objectives: To estimate the prevalence of risk factors of CHD and to assess the knowledge regarding risk factors of CHD among bank employees. Methodology: It was a cross-sectional study for a period of one month. The study population consisted of bank employees working in various banks in Belgaum city. Results: The prevalence of risk factors of CHD was as follows: hypertension 31%, diabetes 21%, high serum total cholesterol 29%, high triglycerides 39%, high LDL cholesterol 19.3%, low HDL cholesterol 17.7%, smoking 26%, sedentary habits 44%, positive family history 12%, overweight / obesity (BMI >25 kg/m2 33% and 26% of the study subjects had truncal obesity. Among these, 55% of the study subjects had at least two of these risk factors. Conclusion: The present study shows a disturbing burden of coronary risk factors in the study population. There is an urgent need to undertake population based measures to reverse the trend.

BACKGROUND: Elevated lipoprotein(a) levels are associated with myocardial infarction (MI) in some but not all studies. Limitations of previous studies include lack of risk estimates for extreme lipoprotein(a) levels, measurements in long-term frozen samples, no correction for regression dilution...... bias, and lack of absolute risk estimates in the general population. We tested the hypothesis that extreme lipoprotein(a) levels predict MI in the general population, measuring levels shortly after sampling, correcting for regression dilution bias, and calculating hazard ratios and absolute risk...... estimates. METHODS AND RESULTS: We examined 9330 men and women from the general population in the Copenhagen City Heart Study. During 10 years of follow-up, 498 participants developed MI.

Anthropometric parameters, blood pressure, lipids levels, glycemia, insulinemia, and body mass index were measured. Statistical analyses were performed by SPSS16.0. Results. The percentage of participants who had MetS defined according to NCEP ATP III, IDF 2005, and JIS 2009 definitions was respectively, 29.5%, 38.4%, and 39.6%. With regard to gender, the prevalence of MetS is higher in men than in women according to IDF 2005 definition (38.5% men versus 38.3% women, P=0.961 and according to JIS 2009 definition (41.8% men versus 38.6% women, P=0.307, whereas, according to NCEP ATP III definition, the prevalence of MetS is higher in women than in men (30% versus 28.6%, P=0.627. The prevalence of MetS increased with increasing age according to the three definitions (P<0.001 and peaked in the oldest age group (≥70 years according to IDF 2005 and JIS 2009. Furthermore, a significant difference in the prevalence of MetS components according to gender was observed. Indeed, the abdominal obesity is the most frequent MetS compound in women group, but hypertension and low HDL-C are the most frequent in men. In addition, according to the three definitions, the most frequent MetS profile in our study is “higher waist circumference, hypertension, and low HDL-C.” Conclusion. The high prevalence of MetS is a serious public health problem in Hammam-Sousse Sahloul community. Higher waist circumference, hypertension, and low HDL-C were the most

Full Text Available AIM: Physical activity (PA confers some protection against development of heart failure (HF but little is known of the role of intensity and duration of exercise. METHODS AND RESULTS: In a prospective cohort study of men and women free of previous MI, stroke or HF with one or more examinations in 1976-2003, we studied the association between updated self-assessed leisure-time PA, speed and duration of walking and subsequent hospitalization or death from HF. Light and moderate/high level of leisure-time PA and brisk walking were associated with reduced risk of HF in both genders whereas no consistent association with duration of walking was seen. In 18,209 subjects age 20-80 with 1580 cases of HF, using the lowest activity level as reference, the confounder-adjusted hazard ratios (HR for light and moderate/high leisure-time physical activity were 0.75 (0.66-0.86 and 0.80 (0.69-0.93, respectively. In 9,937 subjects with information on walking available and 542 cases of HF, moderate and high walking speed were associated with adjusted HRs of 0.53 (0.43-0.66 and 0.30 (0.21-0.44, respectively, and daily walking of ½-1 hrs, 1-2 and >2 hrs with HR of 0.80 (0.61-1.06, 0.82 (0.62-1.06, and 0.96 (0.73-1.27, respectively. Results were similar for both genders and remained robust after exclusion of HF related to coronary heart disease and after a series of sensitivity analyses. CONCLUSIONS: Speed rather than duration of walking was associated with reduced risk of HF. Walking is the most wide-spread PA and public health measures to curb the increase in HF may benefit from this information.

Lessons of nature can be an interesting adventure for students if we allow them to actively participate in such activities. Students must engage in educational activities but thanks to them they also better absorb more knowledge and abilities. These types of activities also require proper preparation of the teacher, who should first get to know the area and next prepare a plan for the trip and also define objectives, tasks and issues that confront students. By providing such training for teachers, you can show various methods and forms of work, which allow to use the resources of the local environment. The area of the Vistula River is such an amazing place in Warsaw (capital of Poland). The phenomenon of this place is its wildness in the heart of the city. Fortunately, urbanization has not destroyed its wildness. Teachers are encouraged to use these unique resources in working with students. During the training they receive information and tools that help them to carry out such activities. Outdoor activities give possibility for cross subjects integration that is essential in modern teaching because in this place the content of different subjects complement each other. During these classes students gain not only the theoretical knowledge but also a comprehensive knowledge and intelligently learn the world around us and experience the processes occurring in the natural environment and cultural heritage. Interesting outdoor activities affect the growth of motivation of young people and affect their interest in natural subjects. During outdoor activities they observe the processes and phenomena in the natural place of their occurrence. Such activities can be treated both as providing the general overview for certain topics as well as its deepening. Students during an outdoor activity acquire abilities and improve practical skills. Also important is the ability to pursue educational goals. Observing the environment, students learn the culture of communing with nature

Following the recommendations of the Commission on Social Determinants of Health (2008), the World Health Organization (WHO) developed the Urban Health Equity Assessment and Response Tool (HEART) to support local stakeholders in identifying and planning action on health inequities. The objective of this report is to analyze the experiences of cities in implementing Urban HEART in order to inform how the future development of the tool could support local stakeholders better in addressing health inequities. The study method is documentary analysis from independent evaluations and city implementation reports submitted to WHO. Independent evaluations were conducted in 2011-12 on Urban HEART piloting in 15 cities from seven countries in Asia and Africa: Indonesia, Iran, Kenya, Mongolia, Philippines, Sri Lanka, and Vietnam. Local or national health departments led Urban HEART piloting in 12 of the 15 cities. Other stakeholders commonly engaged included the city council, budget and planning departments, education sector, urban planning department, and the Mayor's office. Ten of the 12 core indicators recommended in Urban HEART were collected by at least 10 of the 15 cities. Improving access to safe water and sanitation was a priority equity-oriented intervention in 12 of the 15 cities, while unemployment was addressed in seven cities. Cities who piloted Urban HEART displayed confidence in its potential by sustaining or scaling up its use within their countries. Engagement of a wider group of stakeholders was more likely to lead to actions for improving health equity. Indicators that were collected were more likely to be acted upon. Quality of data for neighbourhoods within cities was one of the major issues. As local governments and stakeholders around the world gain greater control of decisions regarding their health, Urban HEART could prove to be a valuable tool in helping them pursue the goal of health equity.

One of the objectives of this large scale cross-sectional study of school children of the Addis Ababa city was to assess the status of rheumatic heart disease (RHD) prophylaxis among rheumatic heart disease patients identified during the survey. Awareness about the presence of the illness in those affected and reasons for poor coverage, when detected, were also assessed. Sixty of the 9388 school children surveyed were found to have rheumatic heart disease. On interviewing parents of the children with rheumatic heart disease, ten acknowledged being informed of their children's cardiac illness. Of these parents, 15% (or 9/60) had some idea that their children had heart disease related to some form of infection. However, only two of the nine (22%) children whose parents had some idea about their disease were on regular monthly benzathine penicillin prophylaxis in the previous 12 months preceding the interview. Three (33%) of the nine children had six or fewer injections in the 12 months preceding the interview. The remaining 4 parents (44%) reported that their children took treatment that included injections only at the time of initial diagnosis several years earlier and had not had any follow up since then. Their reasons for not seeking medical care for their children included lack of information on prophylaxis, inability to pay for the treatment and distance of the health facilities. The lack of awareness and the extremely low rate of regular prophylaxis, therefore, highlight the need for an urgent control programme that takes active case detection, treatment access and health education into consideration.

Full Text Available Nobuyuki Shiba, Hiroaki ShimokawaDepartment of Cardiovascular Medicine, Department of Evidence-Based Cardiovascular Medicine, Tohoku University Graduate School of Medicine, Sendai City, JapanAbstract: The prognosis of patients with chronic heart failure (CHF still remains poor, despite the recent advances in medical and surgical treatment. Furthermore, CHF is a major public health problem in most industrialized countries where the elderly population is rapidly increasing. Although the prevalence and mortality of CHF used to be relatively low in Japan, the disorder has been markedly increasing due to the rapid aging of the society and the Westernization of lifestyle that facilitates the development of coronary artery disease. The Chronic Heart Failure Analysis and Registry in the Tohoku District (CHART-1 study was one of the largest cohorts in Japan. The study has clarified the characteristics and prognosis of Japanese patients with CHF, demonstrating that their prognosis was similarly poor compared with those in Western countries. However, we still need evidence for the prevention and treatment of CHF based on the large cohort studies or randomized treatment trials in the Japanese population. Since the strategy for CHF management is now changing from treatment to prevention, a larger-size prospective cohort, called the CHART-2 study, has been initiated to evaluate the risk factors of CHF in Japan. This review summarizes the current status of CHF studies in Japan and discusses their future perspectives.Keywords: heart failure, aging, Japanese

Full Text Available Many studies have focused on climate change policies and action at the national level, but few have studied policies and action at the city level, especially cities in emerging economies. To address this gap, the present study analyzes the management strategies globally leading cities have developed to address climate change and related issues and compares them with the city strategies of one rapidly urbanizing emerging economy, Turkey. In the analysis, the strategic plans of five leading global cities are compared with those of sixteen Turkish cities. While the leading global cities have specific managerial approaches to mitigate climate change, none of the Turkish cities exhibits any comprehensive approach. Furthermore, while leading global cities modify urban services to reduce greenhouse gas (GHG emissions, few Turkish cities adjust any services to address this challenge. Some Turkish cities propose an increased use of renewable energy sources and modification in their transportation system, but the focus in these plans is the current daily needs of their inhabitants. The findings of this study suggest several climate change strategies both for Turkish cities and cities in other developing countries.

The purpose of this document is to present a comparative study of five algorithms of heart sound localization, one of which, is a method based on radial basis function networks applied in a novel approach. The advantages and disadvantages of each method are evaluated according to a data base of 50 subjects in which there are 25 healthy subjects selected from the University Hospital of Strasbourg (HUS) and from theMARS500 project (Moscow) and 25 subjects with cardiac pathologies selected from the HUS. This study is made under the control of an experienced cardiologist. The performance of each method is evaluated by calculating the area under a receiver operating curve (AUC) and the robustness is shown against different levels of additive white Gaussian noise.
Purpose:The referred pain of the somatic structure,a response of the visceralgia,is often seen in clinic.But ist underlying mechanisms are poorly understood.It is interested that cardiac referred pain ofter appears along the running course of the Heart Meridian(HM),while acupuncture of the acupoints of HM can effectively relieve cardiac pain.In the present study,the neural basis of the relationship among the HM,cardiac referred pain and the heart is investigated by using tri-labeling technique.Methods:Wistar rats are used in the present study.Three fluorescent dyes,fast blue(FB),propidium lodide(PI) and bibenzimide(Bb)are respectively injected into the pericardial sac,the left and right medial-middle band (HM) or lateral sides[rung Meridian(LM),used for control] of the rat forearms.Results:Examination of the sections of the dorsal ganglions shows that more doubly labeled neurons are found in the ipsilateral dorsal root ganglions of C8-T3 nerve segments from HM and the heart,while fewer double-labeled neurons found from LM and the heart.The facts provide direct evidence for existence of dichotomizing fibers of the ganglion neurons.There exists a relative specific connection between the HM and the heart.It also provides a morphological explanation for cardiogenic referred pain and for the specific interrelation between the heart Meridian and the heart of traditional Chinese medicine.

In contemporary town planning protection of urban landscape is a significant issue. It regards especially those cities, where urban structures are the result of ages of evolution and layering of historical development process. Specific panoramas and other strategic views with historic city dominants can be an important part of the cultural heritage and genius loci. Other hand, protection of such expositions introduces limitations for future based city development. Digital Earth observation techniques creates new possibilities for more accurate urban studies, monitoring of urbanization processes and measuring of city landscape parameters. The paper examines possibilities of application of Lidar data and digital 3D-city models for: a) evaluation of strategic city views, b) mapping landscape absorption limits, and c) determination protection zones, where the urbanization and buildings height should be limited. In reference to this goal, the paper introduces a method of computational analysis of the city landscape called Visual Protection Surface (VPS). The method allows to emulate a virtual surface above the city including protection of a selected strategic views. The surface defines maximum height of buildings in such a way, that no new facility can be seen in any of selected views. The research includes also analyses of the quality of simulations according the form and precision of the input data: airborne Lidar / DSM model and more advanced 3D-city models (incl. semantic of the geometry, like in CityGML format). The outcome can be a support for professional planning of tall building development. Application of VPS method have been prepared by a computer program developed by the authors (C++). Simulations were carried out on an example of the city of Dresden.

Receptors form a class of intrinsic membrane proteins (or glycoproteins) defined by the high affinity and specificity with which they bind ligands. Many receptors are associated directly or indirectly with membrane ion channels that open or close after a conformational change of the receptor induced by the binding of the neurotransmitter. Changes in number and/or affinity of cardiac neurotransmitter receptors have been associated with myocardial ischemia and infarction, congestive heart failure, and cardiomyopathy as well as diabetes or thyroid-induced heart muscle disease. These alterations of cardiac receptors have been demonstrated in vitro on membrane homogenates from samples collected mainly during surgery or postmortem. The disadvantage of these in vitro binding techniques is that receptors lose their natural environment and their relationships with the other components of the tissue

In the twenty-first century, the population in China will be increasingly urbanized – focusing the sustainability challenge on cities and raising new challenges to address the urban resilience capacity. During the past two decades, China’s urban policies are state institution-directed, growth-oriented, and land-based, imposing unprecedented challenges on sustainability. Strengthening the capacity of cities to manage resilience appears to be a key factor for cities to effectively pursue sustainable development. The aim of this paper is to explore strategic planning approaches for creating resilient cities in China through a study on Hangzhou City in an integrated framework. Firstly, the paper gives a systematic insight into the structure of Hangzhou City. Secondly, the development trajectory of the urban system is analyzed to understand how the past has shaped the present and to get a broader perspective on its evolution. Thirdly, scenario planning is conducted to explore the adaptive capacity of Hangzhou City under different future conditions. At last, having analyzed the past, present, and future of the urban system, the paper discusses the strategies for resilient planning, which helps to identify factors and trends that might enhance or inhabit the adaptability.

The Metropolitan Area of Mexico City (MAMC) is an outstanding case of a fast urban development with lagging, and thus insufficient, massive transportation facilities. This has given rise to a distorted transportation system that accounts for most of the air pollution problem of the city and constitutes a drag on economic development. In this paper, we first describe the MAMC geographical conditions, its growth in physical and economic terms, its transportation system, the ensuring air pollution problems together with some of the mitigation actions undertaken. Afterwards the results of a survey of the displacements of individuals within the city and the time spent on these are presented, to then draw some considerations on the negative economic impact it represents.

3D city model is a digital representation of the Earth's surface and it's related objects such as building, tree, vegetation, and some manmade feature belonging to urban area. The demand of 3D city modeling is increasing rapidly for various engineering and non-engineering applications. Generally four main image based approaches were used for virtual 3D city models generation. In first approach, researchers were used Sketch based modeling, second method is Procedural grammar based modeling, third approach is Close range photogrammetry based modeling and fourth approach is mainly based on Computer Vision techniques. SketchUp, CityEngine, Photomodeler and Agisoft Photoscan are the main softwares to represent these approaches respectively. These softwares have different approaches & methods suitable for image based 3D city modeling. Literature study shows that till date, there is no complete such type of comparative study available to create complete 3D city model by using images. This paper gives a comparative assessment of these four image based 3D modeling approaches. This comparative study is mainly based on data acquisition methods, data processing techniques and output 3D model products. For this research work, study area is the campus of civil engineering department, Indian Institute of Technology, Roorkee (India). This 3D campus acts as a prototype for city. This study also explains various governing parameters, factors and work experiences. This research work also gives a brief introduction, strengths and weakness of these four image based techniques. Some personal comment is also given as what can do or what can't do from these softwares. At the last, this study shows; it concluded that, each and every software has some advantages and limitations. Choice of software depends on user requirements of 3D project. For normal visualization project, SketchUp software is a good option. For 3D documentation record, Photomodeler gives good result. For Large city

Full Text Available Landscape ecological risk assessment can effectively identify key elements for landscape sustainability, which directly improves human wellbeing. However, previous research has tended to apply risk probability, measured by overlaying landscape metrics to evaluate risk, generally lacking a quantitative assessment of loss and uncertainty of risk. This study, taking Liaoyuan City as a case area, explores landscape ecological risk assessment associated with mining cities, based on probability of risk and potential ecological loss. The assessment results show landscape ecological risk is lower in highly urbanized areas than those rural areas, suggesting that not only cities but also natural and semi-natural areas contribute to overall landscape-scale ecological risk. Our comparison of potential ecological risk in 58 watersheds in the region shows that ecological loss are moderate or high in the 10 high-risk watersheds. The 35 moderate-risk watersheds contain a large proportion of farmland, and the 13 low-risk watersheds are mainly distributed in flat terrain areas. Our uncertainty analyses result in a close range between simulated and calculated values, suggesting that our model is generally applicable. Our analysis has good potential in the fields of resource development, landscape planning and ecological restoration, and provides a quantitative method for achieving landscape sustainability in a mining city.
A permanent total artificial heart, the Jarvik-7, was implanted into a 61-year-old male with a severe cardiomyopathy. Gated radionuclide studies were performed in the patient both prior to surgery and following implantation. Preoperative gated radionuclide cardiac studies revealed marked left ventricular enlargement, severe hypokinesis and a left ventricular ejection fraction of 10%. The right ventricle was moderately enlarged with a 27% ejection fraction. Following implantation of the Jarvik-7 artificial heart, gated cardiac studies were performed with a computer gated by a signal from the heart controller. The left ventricular ejection fraction was 69% and the right ventricular ejection fraction was 62%. This compared to a theoretical ejection fraction of 74% for each ventricle based on chamber anatomy. There was excellent ventricular emptying. Phase analysis showed uniform diaphragm motion. The use of gated cardiac studies in humans may prove helpful in evaluating mechanical problems with the artificial heart, such as manlfunction of the diaphragm, before they become clinically apparent.

Full Text Available Purpose: To investigate postoperative pain control and analgesic use after heart surgery. Methods: 120 patients undergone heart surgery, randomly entered the study. Each patient was asked to score his pain intensity on visual analog scale (VAS at four different occasions. Results: 120 patients aged 59 year-old; including 81 male were enrolled in the study. 69.2% had coronary artery disease and 16.7% had heart-valve problem. Main types of surgeries were coronary artery bypass surgery (70.5% and valve repairement (23%. Duration of ICU stay was 4.78±2.7 days and duration of intubations was 17.38 ± 36.46 hours. Pre-surgery pain relief was administrated to 42% of the subjects and morphine and promethazine was the main pre-surgery analgesia medication. Post surgery analgesic included morphine (injection, petidine (injection and NSAIDS (oral or rectal. According to VAS, mean pain level, 1 and 4 hours after extubation, and before and one hour after transferring to wards was 5.05±2.5, 4.09±2.0, 3.52±1.8, 2.36±1.89, respectively. Although the level of pain reported was mostly moderate, 80% were reported satisfaction with their post-surgery pain management. Conclusion: A closer pain management control is needed for patients after heart surgery. Introduction of newer pain management techniques, medications and dosages could reduce the pain and suffering.

The central area of a city is an important functional unit in many urban studies. It is a region where business concentrates and municipal facilities densely distribute. Traditionally, statistics of economic and social phenomena can be used to delimitate their boundaries. However, traditional methods based on economic and social investigation are labor-intensive and sometimes inaccurate. Alternatively, road networks acting as a kind of infrastructure reflect the association of locations. Thus the concentration of road networks indicates the congestion of social-economic activities and municipal facilities to some extent. Based on density analysis of road networks, the area where roads densely distribute is recognized as the central area of a city. Taking Guangzhou City as an example, the road network was studied on a set of spatial scopes, and the central area was delimitated and analyzed. Results showed that the road-density-based delimitation had to be adjusted according to the road system, and the delimitated area was consistent to the real central area to some extent. Since road data is much accessible, road-based method is useful and practical when short of socialeconomic data.

Cardiac volume mensuration by the roentgenological method was carried out in healthy 220 Korean adolescent, 116 males and 104 females. Predicted heart volume (PHV) and relative heart volume (RHV) were obtained from the following formulae: PHV = K X Broad diameter X Long diameter X Greatest horizontal depth RHV = PHV (total volume in ml)/body surface area (meter squared) The constant, K, represents the product of an ellipsoid area factor and a correction factor for magnification of the cardiac image. Therefore, K value used in this study is 0.42 for 200 cm and 150 cm of the focal-film distance in posterior-anterior and lateral views, respectively. The broad diameter was measured from the junction of the right atrium and the diaphragm to the junction of the pulmonary artery and left atrial appendage. The long diameter was taken from the junction of the superior vena cava and right atrium to the cardiac apex. The greatest horizontal depth of the heart was measured on lateral view. Body surface area was obtained by use of the Du Bolis nomogram. The results were as follows: 1. Predicted roentgenological heart volumes at 16 years to 20 years of age was 449 ± 11.1 ml in makes and 418 ± 7.7 ml in females. It increased with advantage age and height, but was not significantly influenced by changes in body weight in both sexes. 2. Relative heart volume at 16 years to 20 years was 275 ± 5.6 ml/m2 in males, 327 ± 4.1 ml/m2 in females. It increased with advantage age and height, but was not significantly influenced by changes in body weight in both sexes. 3. Roentgenological mensuration was a simple and reliable method in determining the cardiac volume.
Full Text Available INTRODUCTION: A band overlying the in tramural segment of coronary artery - a place where the artery goes through myocardium instead of epicardium is called myocardial bridging (MB. A wide variation of 0.5% - 90.4% occurs in the incidence of MB by the cadaveric and angiographic study. More over the occurrence of atherosclerosis in coronary artery segments under myocardial bridges still remains controversial. And so, the incidence of myocardial brid g es and their association to atherosclerosis formation in cadaveric hearts was done morphologically and histological in this study. METHODS: 30 cadaveric hearts from department of Anatomy were examined. After cleaning the fat from epicardium, course of all three coronary arteries were delineated and observed for presence of MB. In the hearts that exhibited MB, the location, length of MB, its distance from the coronary ostium was measured. Sections were made proximal to MB, under MB and distal to MB in the vessels. The perimeter of the vessels were measured. The section was processed for histological study of intimal – media thickness ratio. RESULT: 24 hearts showed MB in the left anterior interventricular artery. One showed MB in right coronary artery. Multiple MB in single artery was seen rarely. The length of the MB segment was around 4 cm on an average. Mostly the MB is seen in the mid to distal part of the artery. The intima was found to be thinned out in the section of the vessel underneath the MB. CONCLUSION: This study concludes that Left coronary artery is the commonest to have myocardial bridges. But the occurrence of this MB in the distal part of the vessel in contrast to previous studies is an important finding to be noted. The presence of intimal thinning underlying the myocardial bridges questions the previous studies that claimed MB‟s protection of vessels from atherosclerosis
In the interval from February of 1972 through December of 1977, studies were conducted relating to the anatomical feasibility of implanting a total artificial heart system. These studies included both the calf as an experimental animal as well as the ultimate human recipient of the artificial heart system. Studies with the calf included definition of the thoracic anatomy relative to the size, shape, and vascular connections for implanting the blood pump. To test the animal's tolerance to an implanted engine system, mockups of the thermal converter were implanted chronically in various locations within the calf. No problems developed in retroperitoneal or intraperitoneal implants ranging from 8 to 15 months. A study to determine accelerations experienced by an abdominally implanted thermal converter was performed in calves. Under the most severe conditions, accelerations of a maximum of 34 Gs were experienced. The largest effort was devoted to defining the human anatomy relative to implanting an artificial heart in the thorax. From a number of data sources, including cadavers as well as living patients, a quantitative, statistical analysis of the size and shape of the male thorax was obtained. Finally, an in vivo study of a functional intrathoracic compliance bag in a calf demonstrated the feasibility of this method

Abstract The pedigree and genotype data from the Framingham Heart Study were examined for errors. Errors in 21 of 329 pedigrees were detected with the program PREST, and of these the errors in 16 pedigrees were resolved. Genotyping errors were then detected with SIMWALK2. Five Mendelian errors were found following the pedigree corrections. Double-recombinant errors were more common, with 142 being detected at mistyping probabilities of 0.25 or greater.
Full Text Available Smart cities link the city services, citizens, resource and infrastructures together and form the heart of the modern society. As a “smart” ecosystem, smart cities focus on sustainable growth, efficiency, productivity and environmentally friendly development. By comparing with the European Union, North America and other countries, smart cities in China are still in the preliminary stage. This study offers a comparative analysis of ten smart cities in China on the basis of an extensive database covering two time periods: 2005–2007 and 2008–2010. The unsupervised computational neural network self-organizing map (SOM analysis is adopted to map out the various cities based on their performance. The demonstration effect and mutual influences between these ten smart cities are also discussed by using social network analysis. Based on the smart city performance and cluster network, current problems for smart city development in China were pointed out. Future research directions for smart city research are discussed at the end this paper.

The City of Yellowknife maintains a fleet of vehicles and equipment used for public service. Yellowknife's Community Energy Plan (CEP) has a goal to reduce Yellowknife's fleet fuel consumption and greenhouse gas (GHG) emissions by 20 per cent within 10 years. This report examined current fuel consumption for the City of Yellowknife's fleet based on available data and examined options to reduce fleet fuel consumption. It also quantified the reduction in fuel consumption, GHG emissions, as well as the financial impacts of various options. An overview of the City of Yellowknife's fleet of vehicles and equipment was first provided, as well as calculated annual values for fuel consumption, GHG emissions, and energy consumption for the City of Yellowknife's fleet. Two fleet management case studies were presented. Fuel-efficient vehicles on the market that could provide an opportunity to replace some of the City of Yellowknife's fleet of light vehicles, and bylaw vehicles with fuel-efficient vehicles were discussed. These vehicles include hybrid vehicles, smart cars, compressed natural gas vehicles, and compressed-air vehicles. Equipment maintenance for tires, preventive, synthetic oils, and driver training programs were discussed. Anti-idling campaigns and technologies were also examined. The report concluded with a discussion of renewable fuels such as biodiesel and ethanol blended gasoline. Fleet fuel consumption, GHG and financial impacts were provided for each chapter heading. It was concluded that if all of the measures identified in the report were implemented, an overall decrease in GHG emissions of approximately 15 per cent would be achieved. 15 refs., 8 tabs., 8 figs

Objective: To comparatively study the different effects of open heart surgery on brain tissues of patients with congenital and rheumatic heart disease. Methods: Forty patients with congenital heart disease (CHD, CHD group, n=20) or rheumatic heart disease (RHD, RHD group, n=20) underwent on-pump (cardiopulmonary bypass, CPB) heart-beating open heart surgery. Blood samples before CPB, and 20 minutes, 1 hour, 24 hours and 7 days after CPB were collected, and the levels of neuron-specific enolase (NSE) and protein S-100b in the plasma were determined with enzyme-linked immunoadsorbent assay (ELISA), respectively. All the patients were examined with electroencephalogram (EEG) before and 1 week after operation. The changes of NSE, S-100b and EEG compared to verify the difference of postoperative cerebral injury between CHD cases and RHD cases. Results: The plasma level of S-100b increased significantly 20 minutes after CPB and was still higher than the preoperative level at 24 hours after operation in both groups (P<0.01). The plasma level of NSE increased more significantly in the CHD group than in the RHD group 20 minutes after CPB and it returned to the normal level 24 hours after CPB in the CHD group but remained at a high level in the RHD group (P<0.01). The levels of NSE and S-100b returned to the normal levels on the 7th day after CPB. Abnormal EEG was found in 75% of the patients in the CHD group and 60% in the RHD group. Conclusions: On-pump heart-beating open heart surgery can cause certain cerebral injury in the patients with CHD or RHD. The injury was more severe and recovered more quickly in the CHD group than in the RHD group.

Heart valve dysfunction is a relatively common condition in the population, whereas significant heart valve disease is more unusual. The cause of different types of heart valve disease depends on which valve is concerned. Rheumatic heart valve disease, has for a long time been considered to constitute a post-inflammatory condition. During the 1990s it was also shown that the so-called non-rheumatic or degenerative tricuspid aortic stenosis, comprised signs of inflammation. In this study, 118 ...

Full Text Available Recently, places have become like businesses. Forces such as globalization and the new 21st century technology lead to the mobility of the resources. In this newly created situation places found themselves in a position of competing with each other. In order to face this competition places incorporate new concepts such as “marketing” into their development strategies. Concepts such as ‘place competition’, ‘distinguish and competitive advantages of the place’, ‘the brand of the place’ and ‘co-branding’ are key aspects discussed in this paper regarding the case of Cluj-Napoca. In this study we focus on elaborating this key aspects of place marketing from the citizens’ perception. We asked the citizens about their perception concerning: the most representative city brands, the importance of these brands in promoting the city’s image, the differences between their city and others and their perception towards the existence of place competition.
Full Text Available To determine the prevalence of domestic physical violence against women and its associated factors in Sanandaj city, Iran, during the year 2000, this study was conducted. Random sampling of 1000 married women resident in Sanandaj city was conducted and underwent a standard interview as well as completed a 23-part questionnaire. 15 % and 38 % of the women had been assaulted by their husbands during the past year or in their marriage, respectively between 1 and 11 or more occasions. Economic problems were the most frequent cause of domestic quarrel, while there was a significant association between the husband’s educational level and the violence against their wives (P=0.001.The physical violence against housewives was significantly more frequent than the employed ones .The husbands job was also significantly associated with their violence The existence of child or daughter in the family had a preventive role in domestic physical violence against women. Logit Regression Model for prediction of physical violence against women (Y during the marriage was: "Y=0.014- 0.029 woman’s age +0.199 numbers of children -0.238 man’s education +0.589 woman’s job ". This study confirms for Sanandaj city of Iran, the high frequency of physical violence against women by their husbands. Cultural education and supportive measures are essential to control that. Screening protocol for the detection of domestic violence in family planning Health Care System is recommended.

Development of a permanent placement lunar base is the next fundamental step in an international program to explore and settle other planets within our solar system. While technical, operational, managerial and long-term issues must be considered, the establishment of a lunar facility can serve the preliminary needs of manned civilization in space. Numerous issues become apparent in the consideration of the activation of a lunar base. Specific and realistic determinations must be made about various types of interests in addition to the general conjectures given above. These activities include: - Spacecraft landings and vehicle systems - Crew selection, supplies and habitability - Power production and distribution - Risk management - Science and lunar activities - Base planning and configurations - Integrated operations and maintenance - Management. The development and activation of a lunar colony will require careful consideration to the future of space activities and operations in near Earth space. A lunar city, which we call Armstrong city, is defined by its own unique natural environment, available technology, realistic objectives, and common sense. Armstrong City, a preliminary first lunar base, will most probably be serving as an extended "division" of Earth's space exploration offices. The reasons are very simple and practical. -First, the costs of maintaining a permanent space facility will be lower in the long run than the costs of a series of short duration, rotating manned bases, -Second, studies in long-term space habitation can effectively be carried out in relative safety, -Third, the initial tasks which need to be done will define and establish methodologies and issues for development of future extraterrestrial base concepts, and -Fourth, the complexities of the initial facilities necessary to sustain the citizens can be tempered through developing local resources and reproducible research. In order to bring about development of Armstrong City, four

Abstract Background Heart failure is an important cause of cardiovascular morbidity and mortality. Studies to date have not established the prevalence heart failure amongst the minority ethnic community in the UK. T'he aim of the E-ECHOES (Ethnic - Echocardiographic Heart of England Screening Study)is to establish, for the first time, the community prevalence and severity of left ventricular systolic dysfunction (LVSD) and heart failure amongst the South Asian and Black African-Caribbean ethn...
BACKGROUND: Nurses working with patients with advanced heart failure need knowledge that will help us to help patients cope with their situations of chronic illness. However, our knowledge bank is deficient due to the scarcity of inquiry that takes the affected person\\'s point of view as its central focus. AIM: The aim of this study was to describe patients\\' experiences of living with advanced heart failure. METHODS: The study sample (N=9) consisted of male (N=6) and female (N=3) patients with advanced (NYHA classes III-IV) heart failure. The design was qualitative and open unstructured interviews were audio-taped and transcribed verbatim during 2006. RESULTS: Four main themes emerged: Living in the Shadow of Fear; Running on Empty; Living a Restricted life; and Battling the System. The experience of living with advanced heart failure was described as a fearful and tired sort of living characterised by escalating impotence and dependence. CONCLUSIONS: The findings suggest that there may be an illogical but enduring ethos of \\'cure\\' pervading health care worker\\'s attitudes to advanced heart failure care. This mindset might be working to hinder the application of additional or alternative therapies, which might better palliate the physical and psychosocial distress of patients.

Full Text Available This article describes potential lines of research using aerial photographs, focusing particularly on the study of urban areas. The specific case considered is that of Mexico City. After presenting an overview of aerial photography in Mexico, we review the potential of this type of record as a primary source for research. The visual corpus analyzed is composed of about 30 aerial photographs taken between 1932 and 1978. They portray the urban space that is our object of investigation: a downtown intersection in Mexico City, known as el crucero de El Caballito (“the little horse intersection” because an equestrian statue of Carlos IV stood there for nearly 150 years. We examine the collection of photographs taken at this site in order to demonstrate the methodological implications of working with aerial photographs of cities. The backdrop to this proposal is work on documentation, cataloguing and dissemination undertaken at the Laboratorio Audiovisual de Investigación Social (Audiovisual Laboratory for Social Research at the Instituto Mora.
A method has been developed to match corresponding heart regions from functional echocardiographic (Echo) and metabolic fluorine-18-fluoro-2-deoxy-D-glucose ([18F]FDG) positron emission tomography (PET) studies in individual patients. Echo and PET images are spatially correlated by determining homologous anatomical landmarks (the two papillary muscles and the inferior junction of the right ventricle), identifiable in images obtained by both acquisition modalities. Echo-PET image registration is first performed in the plane identified by the three landmarks, using a rigid rotate-translate scale model. The registration parameters are then used to transform the whole PET volume. This allows a consistent Echo-PET regional analysis, according to a segmental subdivision of the heart. The technique was tested on patients. The overlay of Echo and PET registered images proved the reliability of realignment of the three markers and a good spatial correlation of myocardial walls. This approach to image registration could be applied to other acquisition modalities (such as magnetic resonance imaging and single-photon emission tomography), provided that the three anatomical landmarks are visualized.

Full Text Available Objective. To examine the frequency and patterns of association of cardiovascular risk factors with atherosclerosis in five different arterial territories at post-mortem in Mexico City. Methods. We obtained five arterial territories arteries (circle of Willis, coronary, carotid, renal, and aorta of 185 men and women 0 to 90 years of age who underwent autopsy at the Medical Forensic Service of Mexico City. We determined the prevalence and extent of atherosclerotic lesions by histopathology according to the classification of the American Heart Association as early (types I–III and advanced (types IV–VI, and according to the degree of stenosis and correlated with cardiovascular risk factors. Results. Atherosclerotic lesions were identified in at least one arterial territory in 181 subjects (97.8%, with involvement of two ore more territories in 178 subjects (92.2%. Advanced lesions were observed in 36% and 67% of subjects under 15 and between 16 and 35 years, respectively. Any degree of atherosclerosis was associated with the presence of diabetes mellitus, hypertension, overweight, obesity, and smoking, and to a greater extent with the presence of two or more risk factors (P<0.001. However, emerging and advanced athersoclerosis was observed in 53% and 20% people with no risk factors. Conclusions. The study shows a high prevalence of atherosclerosis in all age groups and both sexes. There is considerable development of atherosclerotic disease in subjects without known risk factors.

Full Text Available Background: The coronary sinus is a dilated venous channel opening into the right atrium of the heart. The coronary venous system has gained importance in recent years for electrophysiological procedures like arrhythmia ablation, biventricular pacing and implantation of cardiac pacemakers. The present study aims to study the formation and tributaries of coronary sinus and also the morphology of thebesian valve. Materials and Methods: 30 formalin fixed cadaveric hearts available in the department of Anatomy, Dhanalakshmi Srinivasan Medical College and Hospital, Perambalur, Tamil nadu, was used for the study. The formation and tributaries of coronary sinus were noted. The length of coronary sinus in millimeters was measured from the union of great cardiac vein and left marginal vein upto the opening of the coronary sinus in the right atrium with vernier calipers. The width of the coronary ostium in the right atrium was measured in millimeters with vernier calipers. Results: In 93.33% specimens the coronary sinus was formed by the union of great cardiac vein and left marginal vein. In 3.33% specimens it was formed by the union of great cardiac vein and posterior vein of left ventricle, and in 3.33% specimens it was formed by the union of great cardiac vein and oblique vein of left atrium. The left marginal vein was absent in 2 specimens and small cardiac vein was absent in 1 specimen. The mean length of coronary sinus was 54.98 + 12.2mm. The mean width of coronary sinus ostium was 9.35 + 3.24mm. The Thebesian valve was present in 93.33% specimens and it was semilunar in shape. Conclusion: The knowledge of coronary sinus anatomy will be helpful during electrophysiological procedures.

Progress is reported in heart investigations using the first transit principle and the steady-state procedure for radionuclide scanning. Progress in the first transit principle relies on automated selection of areas of interest. A procedure has been developed which automatically performs the evaluation of the areas corresponding to the right heart, the lungs, and the left heart. A different procedure has been built up for dynamic lung studies with Xe-133 (Radiospirometry), which principally can be applied to any other organ investigation. R-wave time averaged procedures of the heart in steady state can be performed in direct or indirect manner. A direct procedure is described that leads eventually to a cinematographic presentation of the heart kinetics on the computer display. The analysis yields an exact outline of heart ventricles and auricles as prerequisite for determination of ejection fractions and clinically relevant data of the heart function

The paper points to the need to increase their collective consciousness and responsiveness to this issue through intense awareness campaigns and rallies to promote measures as pooling of vehicles, cycling, hybrid cars and efficient rapid public transport systems through institution of measures at individual, community and government levels to ameliorate hindrances to the adoption of environment friendly practices as reported in the observations.
Approximately 16,000 study subjects in the Adult Health Study sample who had received examination at least once during the 20 years (1958 - 78) in Hiroshima or Nagasaki and were found to have neither stroke nor coronary heart disease (CHD) at the initial examination were studied for the incidence of stroke and CHD and the relationship of these to atomic bomb radiation exposure. Their secular trends were also studied. Findings suggestive of a relationship between stroke and radiation exposure among Hiroshima females were first discovered for the years 1969 - 73, that is, 24 - 28 years after A-bomb exposure. In general, this association is supported by the present analysis. Stroke incidence continued to decrease during the present report's period of observation. Analysis by type showed that cerebral infarction and cerebral hemorrhage both decreased, but the decrease of the latter is especially remarkable. The trend to decrease is observed in both sexes and in both cities. A relationship between CHD and radiation exposure was, as noted for stroke, first observed only in Hiroshima females for the years 1969 - 73, but from this analysis it appears that the trend began earlier and the association is getting stronger with the passage of time. Analysis by type showed myocardial infarction (MI), but not angina pectoris, to be related to radiation exposure. The incidence rate for CHD, especially for MI, was almost constant during the observation period, it being 1.2/1,000 person-years on the average. Comparing by sex, the incidence rate was constant in males. In females, the pattern varied with time. There appear to be no between-city differences in secular trends - essentially constant. (author)

Full Text Available Background/ objective: Transient global amnesia (TGA is a temporary amnestic syndrome characterized by lack of other focal neurological deficits. Cerebrovascular disease, migraine and seizures have been suggested as underlying mechanisms. TGA may be a risk factor for cerebrovascular or other neurological events. We studied the relation of TGA, vascular risk factors, brain magnetic resonance imaging (MRI indices of subclinical ischemia and neurological events in a community-based sample. Design/setting: A total of 12 TGA cases were ascertained using standard criteria by experienced neurologists, and matched to 41 stroke- and seizure-free controls. Vascular risk factors, brain MRI findings, and subsequent cerebrovascular or seizure events were compared in cases and controls. Participants: Framingham Heart Study (FHS original and offspring cohort participants were included. Results: No significant differences between the groups were observed in the prevalence of vascular risk factors, or brain MRI measures. Few incident stroke/transient ischemic attacks (TIA (1 event among the cases and 4 in controls or subsequent seizures occurred in either group. Head CT during the acute event (n=11 and brain MRI (n=7 were negative for acute abnormalities. Electroencephalograms (EEG (n=5 were negative for epileptiform activity. Extracranial vascular studies were negative for significant stenosis in all cases. Conclusions: In our community-based study TGA was not related to traditional vascular risk factors, or cerebrovascular disease. However, our study is limited by small sample size and power, and larger studies are required to exclude an association.
Full Text Available Abstract Background The burden of cardiovascular disease (CVD in Britain is concentrated in inner-city areas such as Sandwell, which is home to a diverse multi-ethnic population. Current guidance for CVD risk screening is not established, nor are there specific details for ethnic minorities. Given the disparity in equitable healthcare for these groups, we developed a 'tailored' and systematic approach to CVD risk screening within communities of the Sandwell locality. The key anticipated outcomes were the numbers of participants from various ethnic backgrounds attending the health screening events and the prevalence of known and undiagnosed CVD risk within ethnic groups. Methods Data was collected during 10 health screening events (September 2005 and July 2006, which included an assessment of raised blood pressure, overweight, hyperlipidaemia, impaired fasting glucose, smoking habit and the 10 year CVD risk score. Specific features of our approach included (i community involvement, (ii a clinician who could deliver immediate attention to adverse findings, and (iii the use of an interpreter. Results A total of 824 people from the Sandwell were included in this study (47% men, mean age 47.7 years from community groups such as the Gujarati Indian, Punjabi Indian, European Caucasian, Yemeni, Pakistani and Bangladeshi. A total of 470 (57% individuals were referred to their General Practitioner with a report of an increased CVD score – undetected high blood pressure in 120 (15%, undetected abnormal blood glucose in 70 (8%, undetected raised total cholesterol in 149 (18%, and CVD risk management review in 131 (16%. Conclusion Using this systematic and targeted approach, there was a clear demand for this service from people of various ethnic backgrounds, of whom, one in two needed review from primary or secondary healthcare. Further work is required to assess the accuracy and clinical benefits of this community health screening approach.

@@ Introduction With rapid development and advancement of economy and society, lots of city groups or city belts with ex-tra-large cities as their centers have been formed in China. The regions these city groups lie in usually havewell-developed economy, dense population, and are regional politics and culture centers. Some groups lie in theregions with high level of earthquake activity, such as the Surrounding Capital City Group with the centers of Bei-jing and Tianjin. Once a large earthquake occurs, its influence will spread to very extensive region and its disasterwill be tremendous too. So earthquake resistance and disaster mitigation of city group will be very significant issue.The cities in a group have close distance with each other; they can carry out unified preparation for disaster as onewhole and reduce the heavy load of single city before an earthquake, and have an advantage of prompt mutual-aidafter an earthquake because of close distance. It is especially significant to mitigate the lose of lives. One importantprecondition is that all the cities in one group cannot be exposed to the same level of destroy during one earth-quake. So the division of city group in the region with dense cities distribution shall be very significant to theemergent mutual-aid in early time after a large earthquake. For this goal, the characteristics and correlativity ofearthquake′s impact on cities in one group need to clearly be considered. The cities with similar features and strongcorrelativity of historical earthquake influence have large chance to suffer same level destroy during the futurestrong earthquake and are disadvantage to provide mutual-aid and shall not be divided into one group.
Full Text Available Global city research links the expansion of advanced producer services in major cities to the internationalisation of real estate markets as well as to the spread of (mainly high-rise office complexes. This research, however, has based its findings mainly on cases of the Global North. This paper examines, based on Grant and Nijman’s (2002 suggestion that the “internal spatial organisation of gateway cities in the less-developed world” reflects “the city’s role in the global political economy”, which patterns occur in two metropoles of the Global South. In addition to this, the analysis focuses especially on the driving forces behind the changes in corporate geographies. The analysis is placed in Mexico City and Johannesburg and based on real estate market data (offices as well as background documents on urban development. The outcome shows that in these cities, local transformation processes of the real estate market and office space location are indeed considerably shaped by global market dynamics. However, the findings also indicate that there is no clear scale dependence of the territorial form. In order to comprehensively understand the changes in the corporate geographies therefore, it is necessary to direct more attention to local and national dynamics. The restructuring of the built environment in both cities can only be grasped fully by considering the particular role of local and national governments. This additional entry point to an understanding of shifting corporate geographies helps to put recent dynamics of global capitalism and politics of urban neoliberalism in perspective.

Full Text Available One of the main urban issues is healthy life of residents. Today cities have created mental disaster due to some problems such as crowded, pollutions, high density population and etc. on the other hand , cities especially small cities have natural and appropriate conditions in order to improving urban life quality . So should be planned for using from them. This research is applied. Research method is "descriptive – analytical". Data collected is field. At first, was determined by using kukran method. The sample size is 384 people. In order to using from (GHQ-28 questionnaire (Human, 2005: 131. In this research was evaluated urban quality of Boroujerd city. In order to analyzing of data was used some technique such as: SPSS, Pierson correlation, T test, T Kendall, regression and keroskal. Also, was used questioner for determining sample size. The results shows, there is oriented relation between location and health of residents. Indeed, there is appropriate condition of life quality in welfare location. On the other hand, the most disorder between residents was stress that decreased urban life quality

Prospective studies on the role of psychosocial factors in heart failure development are virtually nonexistent. The authors aimed to address the effect of psychosocial factors on the risk of heart failure hospitalization in men and women free of cardiovascular disease. In 1991-1993, the 8...... population reported some degree of vital exhaustion. The vital exhaustion score was associated with a higher risk of heart failure in a dose-response manner (P <0.002), with high vital exhaustion being associated with a 2-fold higher risk of heart failure in both men (hazard ratio = 1.93, 95% confidence...... population, even a modestly higher risk of heart failure associated with vital exhaustion may be of importance in the planning of future preventive strategies for heart failure....

Background Variability of blood pressure (BP) across outpatient visits is frequently dismissed as random fluctuation around a patient’s underlying BP. Objective: Examine the association between visit-to-visit variability (VVV) of systolic and diastolic BP (SBP and DBP) on cardiovascular disease and mortality outcomes. Design Prospective cohort study Setting Post-hoc analysis of the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT). Participants 25,814 ALLHAT participants. Measurements VVV of SBP was defined as the standard deviation (SD) across BP measurements obtained at 7 visits conducted from 6 to 28 months following ALLHAT enrollment. Participants free of cardiovascular disease events during the first 28 months of follow-up were followed from the month 28 study visit through the end of active ALLHAT follow-up. Outcomes included fatal coronary heart disease or non-fatal myocardial infarction, all-cause mortality, stroke and heart failure. Results There were 1194 cases of fatal CHD or non-fatal MI, 1948 deaths, 606 cases of stroke and 921 cases of heart failure during follow-up. After multivariable adjustment including mean SBP, the hazard ratio comparing participants in the highest versus lowest quintile of SD of SBP (≥14.4 mmHg versus <6.5 mmHg) was 1.30 (1.06–1.59) for fatal coronary heart disease or non-fatal myocardial infarction, 1.58 (1.32–1.90) for all-cause mortality, 1.46 (1.06–2.01) for stroke, and 1.25 (0.97–1.61) for heart failure. Higher VVV of DBP was also associated with cardiovascular disease events and mortality. Limitations Long-term outcomes were not available. Conclusions Higher VVV of SBP is associated with increased cardiovascular disease and mortality risk. Future studies should examine whether reducing VVV of BP lowers this risk.

To study the fear of driving phenomenon the authors contacted 48 subjects who, in response to a newspaper article, had expressed an intense fear of driving in the city of Houston and compared them with an age- and sex-matched control group. The information elicited from the subjects suggested the existence of a driving phobia. No significant differences emerged between the phobic subjects and the controls on relevant driving history and background. Although the phobic subjects reported significantly higher levels of anxiety while driving in normal and difficult situations, most of them reported anxiety of phobic intensity only about difficult driving situations, such as driving on freeways and in congested traffic.

Objectives Evaluate the quality of care provided patients with acute myocardial infarction and compare with similar national and regional data. Design Case series. Setting The Strong Heart Study has extensive population-based data related to cardiovascular events among American Indians living in three rural regions of the United States. Participants Acute myocardial infarction cases (72) occurring between 1/1/2001 and 12/31/2006 were identified from a cohort of 4549 participants. Outcome measures The proportion of cases that were provided standard quality of care therapy, as defined by the Healthcare Financing Administration and other national organizations. Results The provision of quality services, such as administration of aspirin on admission and at discharge, reperfusion therapy within 24 hours, prescription of beta blocker medication at discharge, and smoking cessation counseling were found to be 94%, 91%, 92%, 86% and 71%, respectively. The unadjusted, 30 day mortality rate was 17%. Conclusion Despite considerable challenges posed by geographic isolation and small facilities, process measures of the quality of acute myocardial infarction care for participants in this American Indian cohort were comparable to that reported for Medicare beneficiaries nationally and within the resident states of this cohort.

Intramuscular fat may mediate associations between obesity and physical disability. We examined the associations between muscle attenuation, a proxy for intramuscular fat, and physical function. Paraspinous muscle computed tomography attenuation was obtained on a Framingham Heart Study subgroup (n = 1152, 56 % women, mean age 66 years). Regressions modeled cross-sectional associations between muscle attenuation and mobility disability, grip strength, and walking speed with standard covariates; models additionally adjusted for body mass index (BMI) and visceral adipose tissue (VAT). Separate models investigated associations between VAT and subcutaneous adipose tissue (SAT) and physical function. Per 1 standard deviation decrement in muscle attenuation (i.e., more muscle fat), we observed 1.29 (95 % CI = 1.11, 1.50; p = 0.0009) increased odds of walking speed ≤1 m/s in women and men. This persisted after separate BMI and VAT adjustments (p SAT, similar associations were not observed. Intramuscular fat is associated with increased odds of walking speed ≤1 m/s in both sexes and lower grip strength in men. There were no similar associations for VAT and SAT, highlighting the specificity of intramuscular fat in association with physical function. PMID:26899132

This paper gives an overview of the set up, methodology and the obtained results of the CityDelta (phase 1 and 2) project. In the context of the Clean Air For Europe programme of the European Commission, the CityDelta project was designed to evaluate the impact of emission-reduction strategies on air quality at the European continental scale and in European cities. Ozone and particulate matter (PM) are the main components that have been studied. To achieve this goal, a model intercomparison study was organized with the participation of more than 20 modelling groups with a large number of modelling configurations. Two following main topics can be identified in the project. First, in order to evaluate their strengths and weaknesses, the participating models were evaluated against observations in a control year (1999). An accompanying paper will discuss in detail this evaluation aspect for four European cities. The second topic is the actual evaluation of the impact of emission reductions on levels of ozone and PM, with particular attention to the differences between large-scale and fine-scale models. An accompanying paper will discuss this point in detail. In this overview paper the main input to the intercomparison is described as well as the use of the ensemble approach. Finally, attention is given to the policy relevant issue on how to implement the urban air quality signal into large-scale air quality models through the use of functional relationships. (authors)

According to the investigation of varying parts ofcity and its comparison with country average, it is found that most of socialeconomic and environmental indices are low in comparison with the average valueof the country. Keeping the livestock, low per capita of green area, problems of potable water, weakness of thegarbage collection system, incompetence in wastewater disposal, constructions,air pollution, urban traffic and etc. are the problems of this city making unstable environmental, social and economic conditions of Dahreshar city. Basedon the lack of clarification of all aspects of a sustainable city andimpossibility of presenting the definite solutions to achieve the sustainablecity, there are some solutions to achieve the urban sustainable development ofDahreshar city such as: Increasing urban use density, reduction of reliance oncars in transportation (especially personal cars, modification of citymanagement system, protection and renovation of natural systems around city,reduction of resources consumption to decline the pollutions. It seems that thebasic cause of unsustainability of Dahreshar is dedicated to weakness of citymanagement, and urban management review if presented for its solution (e.g. definiteauthority, plans, goals and executive methods and etc.

Full Text Available To examine the association between depression and clinical outcomes in heart failure (HF in a community cohort.HF patients in Minnesota, United States completed depression screening using the 9-item Patient Health Questionnaire (PHQ-9 between 1st Oct 2007 and 1st Dec 2011; patients with PHQ-9≥5 were labelled "depressed". We calculated the risk of death and first hospitalization within 2 years using Cox regression. Results were adjusted for 10 commonly used prognostic factors (age, sex, systolic blood pressure, estimated glomerular filtration rate, serum sodium, ejection fraction, blood urea nitrogen, brain natriuretic peptide, presence of diabetes and ischaemic aetiology. Area under the curve (AUC, integrated discrimination improvement (IDI and net reclassification improvement (NRI compared depression as a predictor against the aforementioned factors.425 patients (mean age 74, 57.6% males were included in the study; 179 (42.1% had PHQ-9≥5. The adjusted hazard ratio of death was 2.02 (95% CI 1.34-3.04 and of hospitalization was 1.42 (95% CI 1.13-1.80 for those with compared to those without depression. Adding depression to the models did not appreciably change the AUC but led to statistically significant improvements in both the IDI (p = 0.001 and p = 0.005 for death and hospitalization, respectively and NRI (for death and hospitalization, 35% (p = 0.002 and 27% (p = 0.007 were reclassified correctly, respectively.Depression is frequent among community patients with HF and associated with increased risk of hospitalizations and death. Risk prediction for death and hospitalizations in HF patients can be improved by considering depression.

To date, to the best of the authors' knowledge, in almost all of the studies performed around the hemodynamics of bileaflet mechanical heart valves, a heart rate of 70-72 beats/min has been considered. In fact, the heart rate of ~72 beats/min does not represent the entire normal physiological conditions under which the aortic or prosthetic valves function. The heart rates of 120 or 50 beats/min may lead to hemodynamic complications, such as plaque formation and/or thromboembolism in patients. In this study, the hemodynamic performance of the bileaflet mechanical heart valves in a wide range of normal and physiological heart rates, that is, 60-150 beats/min, was studied in the opening phase. The model considered in this study was a St. Jude Medical bileaflet mechanical heart valve with the inner diameter of 27 mm in the aortic position. The hemodynamics of the native valve and the St. Jude Medical valve were studied in a variety of heart rates in the opening phase and the results were carefully compared. The results indicate that peak values of the velocity profile downstream of the valve increase as heart rate increases, as well as the location of the maximum velocity changes with heart rate in the St. Jude Medical valve model. Also, the maximum values of shear stress and wall shear stresses downstream of the valve are proportional to heart rate in both models. Interestingly, the maximum shear stress and wall shear stress values in both models are in the same range when heart rate is St. Jude Medical valve model when heart rate is >90 beats/min (up to ~40% growth compared to that of the native valve). The findings of this study may be of importance in the hemodynamic performance of bileaflet mechanical heart valves. They may also play an important role in design improvement of conventional prosthetic heart valves and the design of the next generation of prosthetic valves, such as percutaneous valves.

This paper discusses the representation of Zhuhai as a special economic zone and famous tourist city in literature. Since Zhuhai was set up, most native writers in Zhuhai have showed narration of struggling experience in “an alien land” for Zhuhai representation. But such literary works benefit little for effectively establishing Zhuhai’s positive city image and confirming its subject identity and spirit. Native writers in Zhuhai should consciously create positive and healthy social climate, ...

Urban Groundwater Mapping (UGM) is a generic term for a collection of procedures and techniques used to create targeted cartographic representation of the groundwater related aspects in urban areas. The urban environment alters the physical and chemical characteristics of the underneath aquifers. The scale of the pressure is controlled by the urban development in time and space. To have a clear image on the spatial and temporal distribution of different groundwater- urban structures interaction we need a set of thematic maps is needed. In the present study it is described the methodological approach used to obtain a reliable cartographic product for Bucharest City area. The first step in the current study was to identify the groundwater related problems and aspects (changes in the groundwater table, infiltration and seepage from and to the city sewer network, contamination spread to all three aquifers systems located in quaternary sedimentary formations, dewatering impact for large underground structures, management and political drawbacks). The second step was data collection and validation. In urban areas there is a big spectrum of data providers related to groundwater. Due to the fact that data is produced and distributed by different types of organizations (national agencies, private companies, municipal water regulator, etc) the validation and cross check process is mandatory. The data is stored and managed by a geospatial database. The design of the database follows an object-orientated paradigm and is easily extensible. The third step consists of a set of procedures based on a multi criteria assessment that creates the specific setup for the thematic maps. The assessment is based on the following criteria: (1) scale effect , (2) time , (3) vertical distribution and (4) type of the groundwater related problem. The final step is the cartographic representation. In this final step the urban groundwater maps are created. All the methodological steps are doubled

Particle number size distributions in a mobility diameter range of 6-1000 nm and size-resolved number concentrations were determined with a time resolution of 10 min for a near-city background, city centre, street canyon and road tunnel environments in Budapest. Median N6-100 concentrations for the sites listed were 3.1 × 103, 9.3 × 103, 19.4 × 103 and 123 × 103 cm-3, respectively. Contributions of the ultrafine (UF) particles (urban sites, and for workdays and weekends. Nucleation strength factor (NSF) was introduced for the first time to quantify the relative importance of new particle formation with respect to all sources of UF particles. During the daytime in summer, nucleation in the near-city background was a major production process of UF particles with a daily mean relative contribution of 42%. In the city centre and street canyon, the daily mean relative contributions of nucleation to the UF particles were 30% and 23%, respectively. Median particle diameters for the background, city centre, street canyon and road tunnel environments were 61, 42, 35 and 42 nm, respectively, so they were jointly influenced with the anthropogenic impact and aerosol ageing. Monthly mean frequency of new particle formation and growth events in the background seems somewhat larger, while it appears smaller for the street canyon in comparison to the city centre.

Full Text Available The study of forecasting identifies the urgent need for special attention in evolving effective energy policies to alleviate an energy famine in the near future. Since power demand is increasing day by day in entire world and it is also one of the fundamental infrastructure input for the development, its prospects and availability sets significant constraints on the socio-economic growth of every person as well as every country. A care full long-term power plan is imperative for the development of power sector. This need assumes more importance in the state of Uttar Pradesh where the demand for electrical energy is growing at a rapid pace. This study analyses the requirement of electricity with respect to the future population for the major forms of energy in the Lucknow city in Uttar Pradesh state of India. A model consisting of significant key energy indicators have been used for the estimation. Model wherever required refined in the second stage to remove the effect of auto-correlation. The accuracy of the model has been checked using standard statistical techniques and validated against the past data by testing for ‘expost’ forecast accuracy.
The work performed since 1993 on the study of the elemental profile of Buenos Aires atmosphere is presented. Both aerosol direct sampling and biomonitors have been used and the samples have been analyzed mainly by Instrumental Neutron Activation Analysis (INAA). Due to problems with XRF, Anodic Stripping Voltammetry has been chosen for lead determination and Ion Chromatography for soluble anions. For aerosol direct sampling, analytical and sampling methods are described, as well as the sampling campaigns. Experiments have been performed for studying differences between day/night elemental concentrations along the week and a possible seasonal dependence. Some results of mass concentrations and others from INAA are presented. Sampling with the 'Gent sampler' began during August 1994 at an urban residential area of the city. The results of mass concentrations for the first 28 pairs of samples are shown together with some INAA results, as this is the only technique used for the analysis. Lichens and tree bark were the chosen biomonitors. Sampling and analytical methods by INAA are exposed, presenting some of the results that have been obtained. The participation in the aerosol analysis for the Ushuaia Global Atmospheric Watch Station is also commented. (author)

Full Text Available The ratio of forced expiratory volume in one second to forced vital capacity (FEV(1/FVC is a measure used to diagnose airflow obstruction and is highly heritable. We performed a genome-wide association study in 7,691 Framingham Heart Study participants to identify single-nucleotide polymorphisms (SNPs associated with the FEV(1/FVC ratio, analyzed as a percent of the predicted value. Identified SNPs were examined in an independent set of 835 Family Heart Study participants enriched for airflow obstruction. Four SNPs in tight linkage disequilibrium on chromosome 4q31 were associated with the percent predicted FEV(1/FVC ratio with p-values of genome-wide significance in the Framingham sample (best p-value = 3.6e-09. One of the four chromosome 4q31 SNPs (rs13147758; p-value 2.3e-08 in Framingham was genotyped in the Family Heart Study and produced evidence of association with the same phenotype, percent predicted FEV(1/FVC (p-value = 2.0e-04. The effect estimates for association in the Framingham and Family Heart studies were in the same direction, with the minor allele (G associated with higher FEV(1/FVC ratio levels. Results from the Family Heart Study demonstrated that the association extended to FEV(1 and dichotomous airflow obstruction phenotypes, particularly among smokers. The SNP rs13147758 was associated with the percent predicted FEV(1/FVC ratio in independent samples from the Framingham and Family Heart Studies producing a combined p-value of 8.3e-11, and this region of chromosome 4 around 145.68 megabases was associated with COPD in three additional populations reported in the accompanying manuscript. The associated SNPs do not lie within a gene transcript but are near the hedgehog-interacting protein (HHIP gene and several expressed sequence tags cloned from fetal lung. Though it is unclear what gene or regulatory effect explains the association, the region warrants further investigation.

Full Text Available High-tech development—which lies at the very heart of the processes of economic growth—has been recognised by many developed and developing countries as a strategic instrument to enhance and sustain their competitiveness in the global economic network. Although the concept of high-tech development differs between countries, many share the underlying assumption that the core of high-tech development is to create a sound environment where innovation thrives. This ideology implies a definite spatial dimension. As a result, various spatial strategies have been formulated and implemented to support high-tech development. This has had intentional and unintentional effects on the economy, society and space.Numerous studies have been devoted to exploring, analysing and theorising this global phenomenon. However, there has been less attention given to the role spatial planning may play in the process of high-tech development and to the factors that shape the spatial planning approaches to high-tech development in a particular place. The major objectives of this research are to advance the knowledge of the role of spatial planning in the process of high-tech development, and to establish an analytical framework that helps reveal the major institutional factors that shape spatial planning mechanisms for dealing with the spatial issues of high-tech development in different places. This contributes to the field of high-tech spatial policies transfer and lesson-drawing.In order to explore the major factors that shape the practices of spatial planning in hightech development, a comparative approach is applied in this research. The Eindhoven city-region in the Netherlands and the Hsinchu city-region in Taiwan are selected as case study areas. Both city-regions can be recognised as success stories of high-tech development not only on a national scale but also on a global scale, despite the fact that they apply different approaches. In the Eindhoven city

Full Text Available Background: Heart failure as a chronic disease poses many challenges for a patient in his or her everyday life. Support in various aspects of life positively affects coping strategies and influences the well-being and health outcomes of heart failure patients. Inadequate support may lead to a worsening of symptoms, increased hospital readmissions, psychological disorders, and a reduced quality of life. Objective: This study explored obstacles to coping related to support for heart failure patients as viewed by the patients themselves and their family members and caregivers. Design: This qualitative study was conducted using content analysis. The 20 Iranian participants included 11 patients with heart failure, three cardiologists, three nurses, and three family members of heart failure patients selected through purposive sampling. Data were collected through semi-structured interviews and analyzed using the Lundman and Graneheim qualitative content analysis method. Results: During data analysis, ‘defective support network’ developed as the main theme along with four other categories of ‘inadequate family performance’, ‘inadequate support by the healthcare team’, ‘distorted societal social support’, and ‘inadequate welfare support’. Conclusion: The findings of the current study can assist health authorities and planners in identifying the needs of patients with heart failure so as to focus and plan on facilitating their coping as much as possible by obviating the existing obstacles.

Full Text Available The Smart City model is now considered one of the opportunities to rethink cities and, in general, the development of urban communities. One of the most relevant themes in the application of the Smart City paradigm is the city/energy relationship and Italian cities are fielding several actions to effectively cope with the energy issues. Nevertheless, actions and projects are often uncritically promoted as ‘smart’, but actually lack innovative contents and methods. Therefore, the aim of this research, of which we present the first findings, is the drafting of a survey, tested through field analysis, of the experimentations of Italian metropolitan areas on the Smart City topic. The in-depth analysis of two case studies, Genoa and Naples, allowed us to compare the actual state of the two cities. We have that they have undertaken a common path in the implementation of strategies to try to transform themselves into Smart Cities, focusing especially on the energy aspects.
Full Text Available Abstract Background Both the act of competing, which can create a kind of mental stress, and participation in motor sports, which induces physical stress from intense g-forces, are known to increase heart rate dramatically. However, little is known about the specific effect of competition on heart rate during motor sports, particularly during four-wheel car driving. The goal of this preliminary study, therefore, was to investigate whether competition increases heart rate under such situations. Findings The participants drove an entry-level formula kart during two competitive races and during solo driving against the clock while heart rate and g-forces were measured. Analyses showed that heart rate values during the races (168.8 beats/min were significantly higher than those during solo driving (140.9 beats/min and rest (75.1 beats/min. Conclusions The results of this preliminary study indicate that competition heightens heart rate during four-wheel car driving. Kart drivers should be concerned about maintaining good health and developing physical strength.
Full Text Available Abstract Background Diagnosing chronic heart failure is difficult, especially in mild cases or early in the course of the disease, and guidelines are not easily implemented in everyday practice. The aim of this study was to investigate general practitioners' diagnostic reasoning about patients with suspected chronic heart failure in comparison with recommendations in European guidelines. Methods Think-aloud technique was used. Fifteen general practitioners reasoned about six case vignettes, representing authentic patients with suspected chronic heart failure. Information about each case was added successively in five steps. The general practitioners said their thoughts aloud while reasoning about the probability of the patient having chronic heart failure, and tried to decide about the diagnosis. Arguments for and against chronic heart failure were analysed and compared to recommendations in guidelines. Results Information about ejection fraction was the most frequent diagnostic argument, followed by information about cardiac enlargement or pulmonary congestion on chest X-ray. However, in a third of the judgement situations, no information about echocardiography was utilized in the general practitioners' diagnostic reasoning. Only three of the 15 doctors used information about a normal electrocardiography as an argument against chronic heart failure. Information about other cardio-vascular diseases was frequently used as a diagnostic argument. Conclusions The clinical information was not utilized to the extent recommended in guidelines. Some implications of our study are that 1 general practitioners need more information about how to utilize echocardiography when diagnosing chronic heart failure, 2 guidelines ought to give more importance to information about other cardio-vascular diseases in the diagnostic reasoning, and 3 guidelines ought to treat the topic of diastolic heart failure in a clearer way.

In this work the three most important non-invasive methods - X-ray pictures, electrocardiography and echo cardiography - were compared as to their ability to evaluate the physiological heart enlargement as a result of physical training. Important also was the study of the value of ultrasonic cardiographs. The subjects used were 162 athletes, 36 patients with cardiovascular diseases, and 22 non-athletic control persons. Radiologically the changes in the total size of the heart were determined. For the question of the adapting reaction of the heart because of athletic training the weight-related heart volume is more meaningful than the absolute value. Electrocardiographically it is not possible to come up with any statistically significant statements about the physiological heart enlargement using the Sokoloff-Lyon indexes. Echo cardiographically the regulative heart enlargements can be differentiated into myocardial hypertrophy or ventricular dilation. As a result of this a line can be drawn between physiological and pathological changes. Female athletes show qualitatively, but not quantitatively, the same adapting reaction. The synopsis of the three procedures shows that echo cardiography and radiology show better results than does electrocardiography. Together the methods complement each other in their diagnostic power. (orig./TRV)
Background Acute allograft rejection is a major cause of early mortality in the first year after heart transplantation in adults. Although endomyocardial biopsy (EMB) is not a perfect "gold standard" for a correct diagnosis of acute allograft rejection, it is considered the best available test and thus, is the current standard practice. Unfortunately, EMB is an invasive and costly procedure that is not without risk. Recent evidence suggests that acute allograft rejection causes delays in ventricular repolarization and thereby increases the cellular action potential duration resulting in a longer QT interval on the electrocardiogram (ECG). No prospective study to date has investigated whether such increases in the QT interval could provide early detection of acute allograft rejection. Therefore, in the Novel Evaluation With Home Electrocardiogram And Remote Transmission (NEW HEART) study, we plan to investigate the potential benefit of daily home QT interval monitoring to predict acute allograft rejection. Methods/design The NEW HEART study is a prospective, double-blind, multi-center descriptive research study. A sample of 325 adult heart transplant recipients will be recruited within six weeks of transplant from three sites in the United States. Subjects will receive the HeartView™ ECG recorder and its companion Internet Transmitter, which will transmit the subject's ECG to a Core Laboratory. Subjects will be instructed to record and transmit an ECG recording daily for 6 months. An increase in the QTC interval from the previous day of at least 25 ms that persists for 3 consecutive days will be considered abnormal. The number and grade of acute allograft rejection episodes, as well as all-cause mortality, will be collected for one year following transplant surgery. Discussion This study will provide "real world" prospective data to determine the sensitivity and specificity of QTC as an early non invasive marker of cellular rejection in transplant recipients

Full Text Available Background: We sought to determine the frequency of the risk factors for congestive cardiac failure (CCF in a tertiary care hospital in Peshawar, Pakistan. Methods: This retrospective, observational study was conducted in the department of cardiology, Postgraduate Medical Institute, Lady Reading Hospital Peshawar, from March 2005 to September 2007. Relevant information regarding the risk factors of CCF was recorded on questionnaires, devised in accordance with the objectives of the study. Results: This study recruited 1019 patients with an established diagnosis of CCF on the basis of clinical findings and pertinent investigations. The study population comprised 583 (57.12% men and 436 (42.78% women. The patients’ age ranged from 6 years to 82 years with a mean age of 48.5 years and a mode of age of 45 years. The distribution of the causative factors of CCF was as follows: ischemic heart disease in 38.56%; hypertension in 26.30%; dilated cardiomyopathies in 10.10%; obstructive and restrictive cardiomyopathies in 5.39%; valvular heart diseases in 9.32%; congenital heart diseases like ventricular septal defects and atrial septal defects in 4.41% and 0.58%, respectively; constrictive pericarditis in 1.07%; pericardial effusion in 0.68%; chronic obstructive pulmonary disease and pulmonary hypertension in 1.47%; thyrotoxicosis in 0.68%; complete heart block in 0.29%; and Paget’s disease in 0.09% of the cases.Conclusion: Ischemic heart disease, hypertension, cardiomyopathy, valvular heart disease, and congenital heart disease were the major contributors to CCF in our patients.

The purpose of the Klamath Falls project is to demonstrate the effectiveness of a combined thermal distribution system and power generation facility. The city of Klamath Falls operates a geothermal district heating system which would appear to be an attractive opportunity to install a power generation system. Since the two wells have operated reliably and consistently over many years, no new sources or resource exploration would be necessary. It appears that it will cost more to construct, operate, maintain and amortize a proposed geothermal facility than the long?term value of the power it would produce. The success of a future project will be determined by whether utility power production costs will remain low and whether costs of construction, operations, or financing may be reduced. There are areas that it would be possible to reduce construction cost. More detailed design could enable the city to obtain more precise quotes for components and construction, resulting in reduction in contingency projections. The current level of the contingency for uncertainty of costs is between $200,000 and $300,000. Another key issue with this project appears to be operation cost. While it is expected that only minimal routine monitoring and operating expenses will occur, the cost of water supply and waste water disposal represents nearly one quarter of the value of the power. If the cost of water alone could be reduced, the project could become viable. In addition, the projected cost of insurance may be lower than estimated under a city?wide policy. No provisions have been made for utilization of federal tax incentives. If a transaction with a third-party owner/taxpayer were to be negotiated, perhaps the net cost of ownership could be reduced. It is recommended that these options be investigated to determine if the costs and benefits could be brought together. The project has good potential, but like many alternative energy projects today, they only work economically if the
Full Text Available Municipal Solid Waste management constitutes a serious problem in many third world cities. Most cities do not collect the totality of wastes generated and of the wastes collected, only a fraction received proper disposal. The insufficient collection and inappropriate disposal of solid wastes represent a source of water, land and air pollution and poses risks to human health and the environment. Over the next several decades globalization, rapid urbanization and economic growth in the developing world tend to further deteriorate this situation. Items that we no longer need or don’t have any further use are falling in the category of waste and we tend to throw them away. In early days people were not facing such big problems of disposals because of availability of space and natural materials but now a day’s congestion in cities and use of non-biodegradable materials in our day life create many problems. It is directly deals with our hygiene and psychology. So, proper management of solid waste has become unavoidable. Two decades of economic growth since 1990 has changed the composition of India wastes. The quantity of MSW generated in India is increasing rapidly due to increasing population and change in lifestyles. Land is scarce and public health and environment resources are precious. The current SWM crisis in India should be approached holistically; while planning for long term solutions, focus on the solving the present problems should maintained. Solid waste Management, its impacts on public health and environment and prospects for the future should further researched. The findings should be disseminated into the public knowledge domain more effectively. The present paper deals with various topics related with solid waste such as it quantity, performance of solid waste management in Kadapa Municipal Corporation, future generation trends in KMC, deficiencies in the present Municipal Solid Waste management system and also keys to reduce it

Full Text Available Abstract Background Heart failure is an important cause of cardiovascular morbidity and mortality. Studies to date have not established the prevalence heart failure amongst the minority ethnic community in the UK. T'he aim of the E-ECHOES (Ethnic - Echocardiographic Heart of England Screening Studyis to establish, for the first time, the community prevalence and severity of left ventricular systolic dysfunction (LVSD and heart failure amongst the South Asian and Black African-Caribbean ethnic groups in the UK. Methods/Design This is a community based cross-sectional population survey of a sample of South Asian (i.e. those originating from India, Pakistan, Bangladesh and Black African-Caribbean male and female subjects aged 45 years and over. Data collection undertaken using a standardised protocol comprising a questionnaire incorporating targeted clinical history taking, physical examination, and investigations with resting electrocardiography and echocardiography; and blood sampling with consent. This is the largest study on heart failure amongst these ethnic groups. Full data collection started in September 2006 and will be completed by August 2009. Discussion The E-ECHOES study will enable the planning and delivery of clinically and cost-effective treatment of this common and debilitating condition within these communities. In addition it will increase knowledge of the aetiology and management of heart failure within minority ethnic communities.

Heart failure is more prevalent among African Americans than in the general population. Metabolomic studies among African Americans may efficiently identify novel biomarkers of heart failure. We used untargeted methods to measure 204 stable serum metabolites and evaluated their associations with incident heart failure hospitalization (n = 276) after a median follow-up of 20 years (1987-2008) by using Cox regression in data from 1,744 African Americans aged 45-64 years without heart failure at baseline from the Jackson, Mississippi, field center of the Atherosclerosis Risk in Communities (ARIC) Study. After adjustment for established risk factors, we found that 16 metabolites (6 named with known structural identities and 10 unnamed with unknown structural identities, the latter denoted by using the format X-12345) were associated with incident heart failure (P < 0.0004 based on a modified Bonferroni procedure). Of the 6 named metabolites, 4 are involved in amino acid metabolism, 1 (prolylhydroxyproline) is a dipeptide, and 1 (erythritol) is a sugar alcohol. After additional adjustment for kidney function, 2 metabolites remained associated with incident heart failure (for metabolite X-11308, hazard ratio = 0.75, 95% confidence interval: 0.65, 0.86; for metabolite X-11787, hazard ratio = 1.23, 95% confidence interval: 1.10, 1.37). Further structural analysis revealed X-11308 to be a dihydroxy docosatrienoic acid and X-11787 to be an isoform of either hydroxyleucine or hydroxyisoleucine. Our metabolomic analysis revealed novel biomarkers associated with incident heart failure independent of traditional risk factors. PMID:23788672
Full Text Available Modern tourism expands through cultural experience, which is reflected in economic, ecological and socio-cultural effects on destinations. Event tourism is a growing market segment and represents a challenge for all destination stakeholders. As the largest town in the Croatian part of Istria, the City of Pula represents a valid basis for the development of event tourism due to its coastal geography and rich cultural and historical heritage from antique, medieval and new age periods. The festival and event organisers in Pula use historical and cultural themes in order to develop annual attractions by which they draw in tourists and brand the destination. In this paper, the hypothesis is set on the lack of benefits from event organisation in the destination (the City of Pula in the ecological, economic and socio-cultural senses. In resolving of research problems with authorised representatives of local boards Arena, Monte Zaro and Stinjan, standardised, semi-structured and problem-centred interviews were conducted for the purposes of contribution to research relative to sustainability and responsibility of events in tourism.
Full Text Available Many steel-based cities in China were established between the 1950s and 1960s. After more than half a century of development and boom, these cities are starting to decline and industrial transformation is urgently needed. This paper focuses on evaluating the transformation capability of resource-based cities building an evaluation model. Using Text Mining and the Document Explorer technique as a way of extracting text features, the 200 most frequently used words are derived from 100 publications related to steel- and other resource-based cities. The Expert Evaluation Method (EEM and Analytic Hierarchy Process (AHP techniques are then applied to select 53 indicators, determine their weights and establish an index system for evaluating the transformation capability of the pillar industry of China's steel-based cities. Using real data and expert reviews, the improved Fuzzy Relation Matrix (FRM method is applied to two case studies in China, namely Panzhihua and Daye, and the evaluation model is developed using Fuzzy Comprehensive Evaluation (FCE. The cities' abilities to carry out industrial transformation are evaluated with concerns expressed for the case of Daye. The findings have policy implications for the potential and required industrial transformation in the two selected cities and other resource-based towns.
Full Text Available Cities are increasingly seen as the places where innovations that can trigger a sociotechnical transition toward urban mobility are emerging and maturing. Processes such as peak car, rail renaissance and cycling boom manifest themselves particularly in cities, and success stories of cities experimenting with specific types of low-energy mobility abound in the academic literature. Nonetheless, innovation is known to be a precarious process requiring favorable circumstances. Using document analysis and in-depth interviews, this study examines the nature of low-energy innovation in the everyday mobility of people in two UK cities with favorable conditions for a transition away from fossil fuels—Brighton and Oxford. It shows that clear differences exist between the two cities in the sorts of innovation that emerge and diffuse as a result of path dependencies, local politics, and financial support from supra-local governments and agencies. While low-energy mobility currently has substantial momentum in both cities, the majority of low-carbon innovations in urban mobility are incremental rather than radical in nature, and their future is often imbued with uncertainty. The autonomy of small- and medium-sized cities as agents in bringing about transformational change toward low-energy urban mobility should not be overestimated.

Myocardial ischemia is the most common and primary cause of myocardium damage. Numerous conventional techniques and methods have been developed for ischemia and reperfusion studies. However, because of damage to the heart sample, most of these techniques can not be used to continuously monitor the full dynamic course of the myocardial metabolic pathway. The nuclear magnetic resonnance (NMR) surface coil technique, which overcomes the limitations of conventional instrumentation, can be used to quantitatively study every stage of the perfused heart (especially after perfusion stoppage) continuously, dynamically, and without damage under normal or designed physiological conditions at the molecular level. In this paper, 31p-NMR was used to study the effects of ischemia and hypoxia on isolated perfused hearts. The results show that complete hypoxia caused more severe functional damage to the myocardial cells than complete ischemia.

The purpose of this study was to explore the experiences, needs, and coping strategies of patients living with heart failure in Singapore. A descriptive qualitative design was used. A purposive sample of 15 informants was recruited from two cardiology wards of a tertiary public hospital in Singapore. Individual face-to-face interviews were conducted with a semistructured interview guideline that was developed based on a review of the literature and a pilot study. Content analysis was adopted to analyze the data, and four main categories were identified: perceived causes, manifestations, and prognosis; enduring emotions; managing the condition; and needs from health care professionals. The informants were overwhelmed with the experience of living with heart failure due to the disruptive and uncertain nature of the condition. This study offers health care professionals practical and useful suggestions when providing holistic care for patients with heart failure. PMID:25724928

Congenital heart diseases are one of the major cardiovascular diseases in developing countries. Most prevalence studies were based on clinical examination of children with echocardiographic confirmation of suspected cases and underestimate its prevalence. The objective of this study was to investigate the prevalence of congenital heart disease in "daara" (Koranic schools) in the city of Dakar and its suburbs on the basis of clinical examination and Doppler echocardiography in school children. This cross-sectional survey was carried out from 9(th) August to 24(th) December 2011, and included a population of 2019 school children aged 5 to 18 years in 16 selected "daaras" under the Academic Inspectorate of Dakar and its suburbs. Anamnestic, clinical and echocardiographic data were recorded in a validated questionnaire. A p heart diseases were detected being a prevalence of 8.9 per 1 000 (95 % CI: 1.8 to 7.9). This included 6 cases of inter-atrial septal aneurysm, 5 cases of peri-membranous ventricular septal defects, 4 cases of patent ductusarteriosus and 3 cases of tetralogy of Fallot. Factors correlated with the presence of congenital heart disease were ageless than 8 (p rheumatic valvular disease, a prevalence of 4.9 per 1 000 (95% CI: 2.4 to 9.1). Our study shows a high prevalence of congenital heart diseases, which is almost identical to the WHO estimates and that ultrasound screening is more sensitive than clinical screening. Reducing the prevalence of these diseases requires implementation of appropriate policies, focusing on awareness and early detection. PMID:25516291

The study of urban areas and their development focuses on cities, their physical and demographic expansion and the tensions and impacts that go along with urban growth. Especially in developing countries and emerging national economies like India, consistent and up to date information or other planning relevant data all too often is not available. With its Smart Cities Mission, the Indian government places great importance on the future developments of Indian urban areas and pays tribute to the large-scale rural to urban migration. The potentials of urban remote sensing and its contribution to urban planning are discussed and related to the Indian Smart Cities Mission. A case study is presented showing urban remote sensing based information products for the city of Ahmedabad. Resulting urban growth scenarios are presented, hotspots identified and future action alternatives proposed.

Full Text Available Most of morphological studies of cities in Java tended to place the elements of traditional urban space such as Alun-alun, Mosque, Palace and Market as the main elements of city. Other elements such as the colonial urban space Resident Office, Fort, Church, Park and so on are often considered separately or placed as a complementary part. Through a morphological study by exploring ten cities in Java, I found both elements of traditional and colonial urban space were set in a unique and various pattern. There are some findings indicating that the elements of colonial urban space significantly influence the city structure as well as those of the traditional ones. Therefore, understanding the urban space form in Java should include and put elements of both of traditional and colonial urban space as an integral part.

The behaviour of the typical diurnal variation of the atmospheric boundary layer (ABL) over cities is a complex function of very numerous environmental parameters. Two types of geographical situations have been retained: (i) inland city only surrounded by uniform fields, (ii) coastal city, thus influenced by the sea/land breeze effect. We have used the three-dimensional Thermal Vorticity-mode Mesoscale (TVM) model developed jointly by the UCL (Belgium) and JRC (Italy). In this study it has been used in 2-D mode allowing to perform many sensitivity runs. This implies that a kind of infinitely wide city has been effectively stimulated, but this does not affect the conclusions for the ABL height. The sensibility study has been performed for two turbulence closure schemes, for various assumptions for the ABL height definition in the model, and for a selected parameter, the soil water content.

Particle Image Velocimetry (PIV) is an important technique in studying blood flow in heart valves. Previous PIV studies of flow around prosthetic heart valves had different research concentrations, and thus never provided the physical flow field pictures in a complete heart cycle, which compromised their pertinence for a better understanding of the valvular mechanism. In this study, a digital PIV (DPIV) investigation was carried out with improved accuracy, to analyse the pulsatile flow field ...
Full Text Available Abstract Introduction Studies in Europe and America showed that tachycardia, less often bradycardia, frequently accompanied partial seizures in Caucasian patients. We determine frequency, magnitude and type of ictal heart rate changes during partial seizures in non-Caucasian patients in Singapore. Methods Partial seizures recorded during routine EEGs performed in a tertiary hospital between 1995 and 1999 were retrospectively reviewed. All routine EEGs had simultaneous ECG recording. Heart rate before and during seizures was determined and correlated with epileptogenic focus. Differences in heart rate before and during seizures were grouped into 4 types: (1 >10% decrease; (2 -10 to +20% change; (3 20–50% increase; (3 >50% increase. Results Of the total of 37 partial seizures, 18 were left hemisphere (LH, 13 were right hemisphere (RH and 6 were bilateral (BL in onset. 51% of all seizures showed no significant change in heart rate (type 2, 22% had moderate sinus tachycardia (type 3, 11% showed severe sinus tachycardia (type 4, while 16% had sinus bradycardia (type 1. Asystole was recorded in one seizure. Apart from having more tachycardia in bilateral onset seizures, there was no correlation between side of ictal discharge and heart rate response. Compared to Caucasian patients, sinus tachycardia was considerably less frequent. Frequency of bradycardia was similar to those recorded in the literature. Conclusions Significant heart rate changes during partial seizures were seen in half of Singaporean patients. Although sinus tachycardia was the most common heart rate change, the frequency was considerably lower compared to Caucasian patients. This might be due to methodological and ethnic differences. Rates of bradycardia are similar to those recorded in the literature.

Coastal cities are particularly vulnerable to flood under the combined effect of multivariable variables, such as heavy rainfall, high sea level and large waves. For better assessment and management of flood risk the combined effect and joint probability should be considered. This paper aims to study the joint impact of rainfall and tidal level on flood risk by estimating the combined risk degree of flood and the joint flood probability. The area of case study is a typical coastal city...
Full Text Available Introduction & Background: By using newer imaging techniques (MRI and MSCT, it is possible to perform functional studies of the heart including, wall mo-tion, chamber volume evaluation, and myocardial mass and wall thickness. While MRI had recently been introduced as the gold standard method for the morphological and functional studies of the heart, recent advances in the number of detectors, rotation time, and reconstruction protocols made Multislice CT (MSCT another new application for functional studies of the heart too. Ordinary raw data for coro-nary CT angiography is sufficient for these functional studies. Apart from the point that which technique is to be used to get a standard and reproducible meas-urement, a proper imaging strategy is necessary. To use MSCT, various softwares are available for these studies. By the use of these two modalities, valvular evaluations are also possible as addressed in many recent publications. In this article the strategy for functional study of the heart is presented and some case studies are also discussed.
Full Text Available Through the presentation of two case studies this paper aims to engage the theoretical debate on the persistence of public space in the contemporary city, and focuses the attention on the way people practice these spaces and on the policies which are regulating their uses. Starting from the description of different ways in which some urban spaces in Rome (Italy are used by two different communities of people, one mainly composed by immigrants and the other by young city users, and the diverse ways in which their different practices are seen and tolerated, the aim of this paper is to reflect on public spaces. Observing how city users practice public spaces, and analysing the way in which these practices are considered, are particularly exciting perspectives that can offer an interesting vision of the spatial and social reality of the city and of hegemonic relations which govern it.

Full Text Available Abstract Background Human heart failure is a complex disease that manifests from multiple genetic and environmental factors. Although ischemic and non-ischemic heart disease present clinically with many similar decreases in ventricular function, emerging work suggests that they are distinct diseases with different responses to therapy. The ability to distinguish between ischemic and non-ischemic heart failure may be essential to guide appropriate therapy and determine prognosis for successful treatment. In this paper we consider discriminating the etiologies of heart failure using gene expression libraries from two separate institutions. Results We apply five new statistical methods, including partial least squares, penalized partial least squares, LASSO, nearest shrunken centroids and random forest, to two real datasets and compare their performance for multiclass classification. It is found that the five statistical methods perform similarly on each of the two datasets: it is difficult to correctly distinguish the etiologies of heart failure in one dataset whereas it is easy for the other one. In a simulation study, it is confirmed that the five methods tend to have close performance, though the random forest seems to have a slight edge. Conclusions For some gene expression data, several recently developed discriminant methods may perform similarly. More importantly, one must remain cautious when assessing the discriminating performance using gene expression profiles based on a small dataset; our analysis suggests the importance of utilizing multiple or larger datasets.

Aims The influences of nonstationarity and nonlinearity on heart rate time series can be mathematically qualified or quantified by multiscale entropy (MSE). The aim of this study is to investigate the prognostic value of parameters derived from MSE in the patients with systolic heart failure. Methods and Results Patients with systolic heart failure were enrolled in this study. One month after clinical condition being stable, 24-hour Holter electrocardiogram was recording. MSE as well as other standard parameters of heart rate variability (HRV) and detrended fluctuation analysis (DFA) were assessed. A total of 40 heart failure patients with a mea age of 56±16 years were enrolled and followed-up for 684±441 days. There were 25 patients receiving β-blockers treatment. During follow-up period, 6 patients died or received urgent heart transplantation. The short-term exponent of DFA and the slope of MSE between scale 1 to 5 were significantly different between patients with or without β-blockers (p = 0.014 and p = 0.028). Only the area under the MSE curve for scale 6 to 20 (Area6–20) showed the strongest predictive power between survival (n = 34) and mortality (n = 6) groups among all the parameters. The value of Area6–2021.2 served as a significant predictor of mortality or heart transplant (p = 0.0014). Conclusion The area under the MSE curve for scale 6 to 20 is not relevant to β-blockers and could further warrant independent risk stratification for the prognosis of CHF patients. PMID:21533258

Background Standing from a bed or chair may cause a significant lowering of blood pressure (ΔBP), which may have severe consequences such as, for example, falls in older subjects. The goal of this study was to develop a mathematical model to predict the ΔBP due to standing in healthy subjects, based on their Heart Rate Variability, recorded in the 5 minutes before standing. Methods Heart Rate Variability was extracted from an electrocardiogram, recorded from 10 healthy subjects during the 5 m...
Full Text Available Probability of abnormal development is high in certain periods when the increased sensitiveness of embryo and fetus takes place. Influence of damaging factors as maternal infection and, consequently, fetal infection is a reason of abnormal development. Morphological characteristics of heart and placenta were studied during the first trimester of prenatal period of ontogenesis. 17 embryos, fetuses and placenta of 4-12 weeks were used. Abortions were made according to medical statements or maternal willing. The abnormal development of primary leaflets of atrioventricular valves, retardation of fetus growth, abnormal position of organs including ectopic heart, and abnormal limbs development were observed.
