  1. Nuclear cardiology

    International Nuclear Information System (INIS)

    Today, nuclear medicine techniques are routinely used in cardiological practice. They include procedures for the atraumatic investigation of different physiological processes in the various structures included in the central circulation: pericardium, myocardium, myocardial adrenergic innervation, cardiac chambers and valves, coronary microcirculation, and great vessels. Beside these in-Vivo procedures, they also comprise of in-Vitro methods for the detection and measurement in blood of various biological molecules of significance in the management of cardiac diseases. A common feature in this collection of in-Vivo and in-Vitro techniques is their ability to provide helpful clinical information for the diagnosis, prognosis and management of cardiac diseases. Their simplicity and safety for the patient allow their repeated use in the follow up of the progress of disease and in the assessment of the efficacy of the therapeutic measures

  2. Nuclear cardiology

    International Nuclear Information System (INIS)

    This thesis deals with two topics in nuclear cardiology. In the first, left ventricular wall motion assessment using Fourier transform of local left ventricular time-activity curves in gated blood pool studies is evaluated. In the second, the interpretation of myocardial perfusion scintigrams is assessed which are obtained with thallium-201 or with another radiopharmaceutical with different physical, but identical biological properties. In all these investigations data acquisition and analysis by computer played an essential role. In chapter 1 the desirable properties of a nuclear medicine computer system are given and the computer system used for this work is described. Wall motion analysis of the left ventricle using Fourier transform of local time-activity curves in the left ventricular region in gated blood pool studies is described in chapter 2. In chapter 3 detection of non-perfused lesions in myocardial perfusion scintigraphy with thallium-201 is described. Detection of partly perfused lesions and the influence of scatter and photon energy on myocardial perfusion scintigraphy is described in chapter 4. (Auth.)

  4. Pediatric nuclear cardiology

    International Nuclear Information System (INIS)

    Nuclear cardiology methods have had less impact upon pediatric cardiology than upon adult cardiology. Most pediatric heart disease results from congenital malformations of the heart and great vessels, which is usually discovered in infancy, and is most often treated definitively in infancy or early childhood. Unfortunately, nuclear medicine techniques are limited in their spatial resolution - structures that overlie each other are separated with difficulty. As a result, nuclear cardiology is usually of limited value in the anatomic characterization of the congenital heart abnormalities. Nevertheless, it has been useful in the detection and quantification of the pathophysiologic consequences of many congenital cardiac malformations. The authors review application of nuclear medicine in pediatric cardiology, and attempt to assess each in terms of its clinical utility

  6. Nuclear cardiology in Iran

    International Nuclear Information System (INIS)

    Nuclear cardiology is one of the most active branches of nuclear medicine and plays important role in diagnosis in treatment of CAD patients. Few nuclear cardiology surveys were published in the literature, mostly from developed countries. A nuclear cardiology survey in Iran and analysis of the findings in comparison with other countries may lead to better decision making and improve practice in our country. A questionnaire was sent by mail or e-mail to all nuclear medicine centers in Iran asking for details of nuclear cardiology practice. Also ownership of the centers, number of gamma cameras and number of cardiac studies in each week were recorded. Some centers were studied using telephone interview. From 79 nuclear medicine centers in Iran, 55 centers (69.6%) filled the questionnaire including 28 centers in Tehran and 27 centers in other cities. There was 69 Gamma cameras in these centers, 62.3% with SPECT capability. It is estimated that we may have 100 gamma cameras in Iran. This study showed that about 68287 cardiac studies were done in Iran each year with Myocardial perfusion scan accounting for about 99 2% of the studies. Considering population of the country nuclear cardiology activity will be about 1.05 study/1000/year. Regarding radiotracers used, about 13.5% of studies were done with T I-201, with some centers using only Tc-99m-M I B I

  8. Myocardial perfusion scintigraphy: the evidence. A consensus conference organised by the British Cardiac Society, the British Nuclear Cardiology Society and the British Nuclear Medicine Society, endorsed by the Royal College of Physicians of London and the Royal College of Radiologists

    International Nuclear Information System (INIS)

    This review summarises the evidence for the role of myocardial perfusion scintigraphy (MPS) in patients with known or suspected coronary artery disease. It is the product of a consensus conference organised by the British Cardiac Society, the British Nuclear Cardiology Society and the British Nuclear Medicine Society and is endorsed by the Royal College of Physicians of London and the Royal College of Radiologists. It was used to inform the UK National Institute of Clinical Excellence in their appraisal of MPS in patients with chest pain and myocardial infarction. MPS is a well-established, non-invasive imaging technique with a large body of evidence to support its effectiveness in the diagnosis and management of angina and myocardial infarction. It is more accurate than the exercise ECG in detecting myocardial ischaemia and it is the single most powerful technique for predicting future coronary events. The high diagnostic accuracy of MPS allows reliable risk stratification and guides the selection of patients for further interventions, such as revascularisation. This in turn allows more appropriate utilisation of resources, with the potential for both improved clinical outcomes and greater cost-effectiveness. Evidence from modelling and observational studies supports the enhanced cost-effectiveness associated with MPS use. In patients presenting with stable or acute chest pain, strategies of investigation involving MPS are more cost-effective than those not using the technique. MPS also has particular advantages over alternative techniques in the management of a number of patient subgroups, including women, the elderly and those with diabetes, and its use will have a favourable impact on cost-effectiveness in these groups. MPS is already an integral part of many clinical guidelines for the investigation and management of angina and myocardial infarction. However, the technique is underutilised in the UK, as judged by the inappropriately long waiting times and by

    Nuclear cardiology is one of the major fields of nuclear medicine practice. Myocardial perfusion studies using single-photon emission computed tomography (SPECT) have played a crucial role in the management of coronary artery diseases. Positron emission tomography (PET) has also been considered an important tool for the assessment of myocardial viability and perfusion. However, the recent development of computed tomography (CT)/magnetic resonance imaging (MRI) technologies and growing concerns about the radiation exposure of patients remain serious challenges for nuclear cardiology. In response to these challenges, remarkable achievements and improvements are currently in progress in the field of myocardial perfusion imaging regarding the applicable software and hardware. Additionally, myocardial perfusion positron emission tomography (PET) is receiving increasing attention owing to its unique capability of absolute myocardial blood flow estimation. An F-18-labeled perfusion agent for PET is under clinical trial with promising interim results. The applications of F-18 fluorodeoxyglucose (FDG) and F-18 sodium fluoride (NaF) to cardiovascular diseases have revealed details on the basic pathophysiology of ischemic heart diseases. PET/MRI seems to be particularly promising for nuclear cardiology in the future. Restrictive diseases, such as cardiac sarcoidosis and amyloidosis, are effectively evaluated using a variety of nuclear imaging tools. Considering these advances, the current challenges of nuclear cardiology will become opportunities if more collaborative efforts are devoted to this exciting field of nuclear medicine. PMID:27540423

  13. Diagnostic standards in nuclear cardiology

    International Nuclear Information System (INIS)

    Establishing the accurate diagnosis and the adequate treatment of choice in ischemic heart disease (IHD) has become an emergency issue, with increasing the number of IHD patients in Japan. It is therefore important to determine myocardial viability and its related pathophysiology such as stunning and hibernation, which is a prerequisite for widely performed coronary revascularization. From these points of view, cardiovascular nuclear medicine, involving thallium-201 myocardial perfusion scintigraphy and cardiac radionuclide angiography, has become a well-established method for diagnosing IHD. However, no diagnostic standards are available in the routine practice. The Japanese Circulation Society has started a committee for preparing 'diagnostic standards in nuclear cardiology' in April 1989. Out of 8,947 facilities nationwide, 1,126 (12.5%) possess gamma cameras. Of these facilities, 799(70.9%) perform nuclear cardiologic examination. A questinnaire was sent to the 799 facilities, and 410 (51.3%) responded. Based on the 1989's questionnaire results, 'diagnostic standards in nuclear cardiology' was discussed through one year in 1990, and was completed in 1991. This is a report dealing with the present 'diagnostic standards in nuclear cardiology', focusing on thallium-201 myocardial perfusion imaging, cardiac radionuclide angiography, Tc-99m acute infarct imaging, and new radionuclides and PET. Items are included as follows: (1) equipment and techniques, (2) diagnostic standards, (3) stress test, (4) candidates for the examination, and (5) diagnostic cautions. (N.K.) 71 refs

  15. Nuclear cardiology for developing countries

    International Nuclear Information System (INIS)

    The role of nuclear medicine in developing countries must be oriented to the local needs for clinical practice, the health care of large populations and the demands for research with sometimes extremely limited resources. To help define the locally differing needs, it is stressed that nuclear medicine provides the unique opportunity to observe the body at the molecular level of organization and thus makes the body biochemically transparent. Depending on the particular diagnostic demands, complex imaging with gamma scintigraphy or emission tomography may be the only method to choose in some instances, but for others it may be an unnecessary luxury. Nuclear cardiology, with the purpose of non-invasively assessing cardiac function, myocardial perfusion and myocardial metabolism, is a particular challenge in both respects for developing countries. Given such requirements, single-probe devices with multipurpose application are less expensive than gamma cameras and promise advanced diagnostic uses. In one examination, left ventricular function, global cardio-pulmonary circulation and the general circulatory adaptation to exercise can be investigated by non-gated simultaneous blood pool measurements over four lung regions, the heart and the liver. In addition, such devices have the advantages of compactness, robustness and electronic stability. Despite enormous difficulties regarding funding, infrastructure, equipment and maintenance, developing countries should be encouraged to participate in the evolution of nuclear medicine by responding and adapting to defined needs and perhaps by maintaining at least one national centre of excellence with capacities for research and training. Funds are best secured by providing an indispensable service in co-operation with the various clinical disciplines. (author)

  16. Nuclear cardiology in the UK: activity and practice 1997

    International Nuclear Information System (INIS)

    A questionnaire was sent to 251 nuclear medicine centres asking for details of nuclear medicine activity, and nuclear cardiology activity and practice in 1997. One hundred and seventy-one (68%) centres replied. Nuclear medicine activity was estimated at 11.8 studies/1,000 population/year, and 9.5% of these studies were within cardiology (1.12 studies/1,000/year). Myocardial perfusion imaging (MPI) studies accounted for 77% and radionuclide ventriculography (RNV) for 22% of all nuclear cardiology. On a national basis this represents activity levels of 0.86 and 0.25 studies/1,000/year for MPI and RNV, respectively. Of the 171 responding centres, 102 (60%) performed MPI studies and 81 (79%) of these reported that activity was increasing. However, MPI activity was unevenly distributed between hospitals. Two centres accounted for 13% of total MPI; others had far lower activity rates, and 51/102 (50%) centres performed less than 200 MPI studies/year. Comparison with previous surveys showed that nuclear medicine activity had almost doubled since 1990 (it was 6.0 studies/1,000 population in 1990, 9.3 studies/1,000 in 1994 and 11.8 studies/1,000 in 1997). Over the same period, nuclear cardiology activity had also risen, the greatest increase being seen for the last 3 years (it was 0.7 studies/1,000 population in 1990, 0.82 studies/1,000 in 1994 and 1.12 studies/1,000 in 1997). Despite these encouraging figures, MPI activity for 1997 remained well below that recommended by the British Cardiac Society in 1994 (2.6 studies/1,000/year) as adequate to serve the needs of patients with cardiac disease in the UK; it was also below the European average activity for the same year (2.2 studies/1,000/year). The anticipated increased workload for nuclear cardiology is encouraging despite the wide and varied practice of nuclear cardiology around the UK. The nuclear medicine community now needs to address the issues that will prevent it keeping up with demand, such as restricted camera

  18. Evaluating the benefits of nuclear cardiology

    International Nuclear Information System (INIS)

    This paper reviews the role of nuclear cardiology in the context of health care evaluation and resource utilisation. Nuclear cardiology procedures are used to detect disease, to define the extent of disease, to predict the outcome of therapy and to monitor the response to treatment. The evaluation of effectiveness will depend on the role for which the tests are being used. The evaluation of diagnostic tests most commonly follows the five level Fineberg classification. I) Technical capacity; II) diagnostic accuracy; III) diagnostic impact; IV) therapeutic impact; V) patient outcome. Tests may succeed or fail at each of these hierarchical levels. In addition to the clinical impact which is evaluated, the appropriate use of health care resources has to be considered , i.e. the cost effectiveness of the investigation. For this the costs of diagnosis and treatment in the resources used, together with the direct cost on the patient and patient carers needs to be considered. In addition to these direct costs to the community and to the patient and the carers the secondary downstream costs and opportunity costs have to be taken into account. The common methods for assessing the costs and benefits include cost minimization, cost effectiveness, cost utility, and cost benefit studies. The advantage and appropriate use of these methods are reviewed. There are seven clinical methods for evaluating diagnostics tests in nuclear cardiology which are: I) Case reports; II) consensus studies; III) databases; IV) management impact studies; V)modeling techniques; VI) management impact studies; VII) randomized control trial. Each of these has a role with advantages and disadvantages which are reviewed. It is no long sufficient to investigate the usefulness of a diagnostic test used in nuclear cardiology in isolation but it as to be within the context of the health care system and the resource used

    The prevalence of heart failure in the adult population is increasing. It varies between 1% and 2%, although it mainly affects elderly people (6-10% of people over the age of 65 years will develop heart failure). The syndrome of heart failure arises as a consequence of an abnormality in cardiac structure, function, rhythm, or conduction. Coronary artery disease is the leading cause of heart failure and it accounts for this disorder in 60-70% of all patients affected. Nuclear techniques provide unique information on left ventricular function and perfusion by gated-single photon emission tomography (SPECT). Myocardial viability can be assessed by both SPECT and PET imaging. Finally, autonomic dysfunction has been shown to increase the risk of death in patients with heart disease and this may be applicable to all patients with cardiac disease regardless of aetiology. MIBG scanning has a very promising prognostic value in patients with heart failure. (orig.)

  2. Filter's importance in nuclear cardiology imaging

    International Nuclear Information System (INIS)

    Full text: Nuclear Medicine is a medical speciality which employs tomography procedures for the diagnosis, treatment and prevention of diseases. One of the most commonly used apparatus is the Single Photon Emission Computed Tomography (SPECT). To perform exams, a very small amount of a radiopharmaceutical must be given to the patient. Then, a gamma camera is placed in convenient positions to perform the photon counting, which is used to reconstruct a full 3 dimensional distribution of the radionuclide inside the body or organ. This reconstruction provides a 3-dimensional image in spatial coordinates, of the body or organ under study, allowing the physician to give the diagnostic. Image reconstruction is usually worked in the frequency domain, due to a great simplification introduced by the Fourier decomposition of image spectra. After the reconstruction, an inverse Fourier transform must be applied to trace back the image into spatial coordinates. To optimize this reconstruction procedure, digital filters are used to remove undesirable components of frequency, which can 'shadow' relevant physical signatures of diseases. Unfortunately, the efficiency of the applied filter is strongly dependent on its own mathematical parameters. In this work we demonstrate how filters interfere on image quality in cardiology examinations with SPECT, concerning perfusion and myocardial viability and the importance of the medical physicist in the choice of the right filters avoiding some serious problems that could occur in the inadequate processing of an image damaging the medical diagnosis.

  3. Comparison of nuclear cardiology in the United States and Europe

    International Nuclear Information System (INIS)

    Nuclear Cardiology is a widely available and a widely accepted tool for diagnosis and management of coronary artery disease both in the US and in Europe. Although the most common indications for nuclear studies are similar in the US and Europe, different social and economical environments may affect the practice of Nuclear Cardiology. The aim of this paper is to identify key issues and to provide some information on the similarities and differences which characterize the practice of Nuclear Cardiology in the US and Europe. This paper takes into account the training requirements, the relationships between different professional societies, the accessibility, the choice of imaging protocols, tracers and stressors, the impact of managed care and the role of cardiologists, nuclear physicians and technologists in nuclear labs. The economical differences which may affect the field of high technology, imply a wide range of variability concerning the availability of nuclear cardiology studies in different countries (1:1/10). Moreover the legislation which regulates the practice of nuclear medicine may differ from country. Thus in our opinion there are several important factors both in the US and Europe limiting the development of nuclear cardiology independently of its intrinsic clinical value

  4. Methods and clinical applications in nuclear cardiology: a position statement

    International Nuclear Information System (INIS)

    Nuclear cardiological procedures have paved the way for non-invasive diagnostics of various partial functions of the heart. Many of these functions cannot be visualised for diagnosis by any other method (e.g. innervation). These techniques supplement morphological diagnosis with regard to treatment planning and monitoring. Furthermore, they possess considerable prognostic relevance, an increasingly important issue in clinical medicine today, not least in view of the cost-benefit ratio. Our current understanding shows that effective, targeted nuclear cardiology diagnosis - in particular for high-risk patients - can contribute toward cost savings while improving the quality of diagnostic and therapeutic measures. In the future, nuclear cardiology will have to withstand mounting competition from other imaging techniques (magnetic resonance imaging, electron beam tomography, multislice computed tomography). The continuing development of these methods increasingly enables measurement of functional aspects of the heart. Nuclear radiology methods will probably develop in the direction of molecular imaging.

  5. Leukaemia near british nuclear installations

    International Nuclear Information System (INIS)

    An excess of childhood leukaemia has been seen near some British nuclear installations, especially near the Sellafield reprocessing plant. The same result was found in a more general study including a large number of nuclear sites. Similar studies made in USA, Canada and France have been negative. Moreover, epidemiological studies made in England have discovered other childhood leukaemia clusters in areas far from nuclear facilities, and especially near potential sites of nuclear installations. Several explanations are suggested but no definite conclusion is yet possible. Doses from radioactive releases seem to be too low to account for the additional deaths from leukaemia by environmental contamination. A virus activation, which might be associated with population influx into rural isolated areas, has been considered. The hypothesis of genetic mutation induced by ionising radiation in the fathers of children with leukaemia has been made because a higher risk of leukaemia was observed for children of fathers employed at Sellafield. No firm conclusion is possible considering the small number of observed cases and the lack of excess leukaemias in the offspring of Hiroshima and Nagasaki survivors. The possibility of internal contamination, chemicals or even radon is discussed as other causes. Studies in progress might allow to find an answer to the problem of leukaemia in the vicinity of British nuclear installations

  6. Nuclear Cardiology. Guidance and Recommendations for Implementation in Developing Countries

    International Nuclear Information System (INIS)

    Nuclear cardiology represents one of the most widely used non-invasive techniques for the assessment of coronary artery disease and other cardiovascular conditions. It has been proven as a cost effective tool for the management of cardiac patients and usually has a decisive role in diagnosis, prognosis and risk stratification, as well as in evaluation of therapy. Clinical scenarios in which nuclear cardiology can be helpful are continuously expanding, with the identification of special subgroups of patients as potential beneficiaries of these methods and the emergence of technological developments in instrumentation and software that tend to enhance the cost-benefit ratio and the reliability of results. Many developing countries have introduced nuclear cardiology, with increasing use of this technique in view of the epidemic of cardiovascular disease that is taking place in most low to middle income countries. Longer life expectancies, changes in lifestyle, diabetes, overweight and obesity are thought to be some of the factors underlying the rapidly growing incidence of this life threatening condition. Today, cardiovascular diseases are the most common cause of death in adults in most, if not all, countries of the world, although specific diseases show different relative weights according to local socioeconomic conditions. Thus, proper utilization of available resources such as nuclear cardiology and other imaging methods is essential to effectively combat these diseases. The practice of nuclear cardiology, however, is not homogeneous worldwide, owing to differences in technological capabilities, availability of consumables, education and training of human resources, and access to evidence based medicine, among other factors. Evidence based medicine is the judicious use of current best evidence in making decisions about the care of individual patients. The practice of evidence based medicine means integrating individual clinical expertise with the best available

  7. Radioisotopes and radiopharmaceuticals in nuclear cardiology

    International Nuclear Information System (INIS)

    Nuclear medicine studies of the heart represent one of the fastest growing areas of research and clinical interest. Some years ago, nuclear medicine cardiac studies were limited to the evaluations of myocardial infraction. Developments in radiopharmaceuticals chemistry and instrumentation have made possible advances in cardiovascular nuclear medicine. Techniques and Radiopharmaceuticals no exist for the imaging of viable myocardium and the determination of myocardial tissue metabolism, as well as radionuclide angiography to obtain quantitative information of cardiac output, mean transit times, cardiac volumes, and ejection fractions. This paper will firstly describe that anatomy and physiology of the heart as to relate to the radiopharmaceuticals which will be discussed, and will secondly explore various radiopharmaceuticals which have been used for various purposes in cardiac imaging, than will explore radioisotopes which have been proposed for myocardial treatment

  8. Nuclear cardiology in Senegal: a luxury or a need?

    International Nuclear Information System (INIS)

    Aim: to sensitize at the same time experts and public authorities on the interest of the establishment of nuclear cardiology in Senegal. Material and method: the radioimmunoassay of micro-albuminuria, early marker of cardiovascular morbid-mortality was carried out in the nuclear medicine department of Dakar on a population of 100 diabetic patients (74 of type 1 and 26 of type 2) presenting one or more traditional cardiovascular risk factors. Out of these patients, 39% had abnormal rest ECG, asymptomatic in half of the cases. Results: prevalence of micro-albuminuria is high (24%). There is no significant difference in distribution between type I and type 2. Micro-albuminuria > 30 mg/24 h exists in 16,3% of patients with lipid abnormalities (ratio: total cholesterol/HDL cholesterol > 5), 30% of obese, 75% of hypertensive patients and 43,6% of patients with abnormal rest ECG, who would benefit from myocardial perfusion imaging (MPI): about 17% of patients involved in this study. No or weak correlation is found between micro-albuminuria and traditional risk factors. Conclusion: From these results and available epidemiological data in 2005, the estimate of the requirements in nuclear cardiology for the Senegalese diabetic population, indicates that 3740 patients should have benefited that year from it. Considering that this figure underestimates the real needs, taking into account the needs brought back to a population of 10 million inhabitants and the expect expansion of the diabetic disease, it appears justified to include the nuclear cardiology in the national programmes of prevention of the public health in Senegal.

  9. Current status of nuclear cardiology in the Republic of Korea

    International Nuclear Information System (INIS)

    Since its introduction 20 years ago, nuclear cardiology in the Republic of Korea has grown impressively and is now widely used as a noninvasive procedure in the diagnosis and functional evaluation of various types of heart diseases. All of the classes of procedures, that is, first-pass radionuclide cardioangiography, gated blood pool scan, myocardial perfusion imaging, and myocardial infarct imaging, are being employed frequently and have been the subject of numerous studies. First-pass radionuclide ventriculography is being used in the detection and quantification of intracardiac shunts, the evaluation of chamber size, function, or cardiopulmonary dynamics in various disease states. With gated blood pool scans, several parameters of cardiac function are being measured in a variety of conditions including coronary heart disease. Quantifications of regurgitations are also being done. Both thallium-201 and technetium-99m pyrophosphate are being used in the diagnosis of coronary artery disease. Besides clinical imaging, active research in the field of nuclear cardiology has also been taking place in the Republic of Korea. Examples include investigations on new imaging agents such as 111In-antimyosin monoclonal antibody and hexakis technetium(I) cations, or instrumental developments such as the nuclear stethoscope. Despite such noteworthy accomplishments, however, there have also been some obstacles to further developments in the Republic of Korea, such as the unavailability of a cyclotron. Nevertheless, considering the rate of expansion these procedures are showing and the effort we are putting into further development, the future for nuclear cardiology in the Republic of Korea appears quite promising and may become an example for other developing countries.

    Nuclear myocardial perfusion imaging is very effective in the evaluation of patients with suspicious acute coronary syndrome (ACS), for adequate diagnosis and treatment. There have been many clinical evidences to support the efficacy and cost-effectiveness. In addition, many authoritative guidelines support the utility of myocardial perfusion imaging in ACS with an appropriate diagnostic protocol. However, with the development of other cardiac imaging modalities, the choice of modality for the diagnosis of suspicious ACS now depends on the availability of each modality in each institute. Newly developed imaging technologies, especially including molecular imaging, are expected to have great potential not only for diagnosis but also for primary, secondary, and tertiary prevention of ACS.

  12. Nuclear cardiology in the era of cardiac CT and MRI

    International Nuclear Information System (INIS)

    Full text: Current indications for classical nuclear cardiology are summarized (diagnosis, prognosis, myocardial viability, ventricular function). First, the use of nuclear cardiology is discussed within the clinical context (typical vs. atypical history of ischemia, findings on resting ECG etc.). An overview of different perfusion tracers is given both for SPECT (thallium, MIBI, microspheres) and PET (NH4, H2O, Rb). The advantages of gated imaging are mentioned, thus combining information regarding perfusion, ventricular function, regional wall motion and thickening. Then specificity and sensitivity data for detection of significant coronary artery disease are reviewed in both diabetic and non-diabetic patients: sensitivity values of 86% are reached for coronary artery stenosis of >50% in both populations. Sensitivity increases to around 90% for coronary artery stenosis of >70%. The issue of risk stratification and prognosis in both populations is raised: Negative predictive values as high as 0.97 for death and 0.94 for death or myocardial infarction are reached when patients have normal myocardial perfusion scans (follow-up 23+/-17 months). The current strengths and weaknesses of CT and MR imaging for detection of coronary artery disease are mentioned, including dobutamine stress MRI and perfusion imaging. With dobutamine stress MRI, sensitivity values between 83% and 91% are observed. When comparing dobutamine stress MRI with dobutamine echocardiography, image quality has a huge impact on sensitivity and specificity values with echo, but only minimal impact on MRI sensitivity/specificity values. In a second part of the talk, the advantages of positron emission tomography (PET) and its use in clinical cardiology (mainly detection of viability) are discussed. First, advantages of positron tomography are listed: short half life of the tracer, physiological labelling, absolute quantification, tomographic imaging. Different cardiac tracers are mentioned, such as

  13. Clinical and economic outcomes assessment in nuclear cardiology

    International Nuclear Information System (INIS)

    The future of nuclear medicine procedures, as understood within our current economic climate, depends upon its ability to provide relevant clinical information at similar or lower comparative costs. With an ever-increasing emphasis on cost containment, outcome assessment forms the basis of preserving the quality of patient care. Today, outcomes assessment encompasses a wide array of subjects including clinical, economic, and humanistic (i.e., quality of life) outcomes. For nuclear cardiology, evidence-based medicine would require a threshold level of evidence in order to justify the added cost of any test in a patient's work-up. This evidence would include large multicenter, observational series as well as randomized trial data in sufficiently large and diverse patient populations. The new movement in evidence-based medicine is also being applied to the introduction of new technologies, in particular when comparative modalities exist. In the past 5 years, it has seen a dramatic shift in the quality of outcomes data published in nuclear cardiology. This includes the use of statistically rigorous risk-adjusted techniques as well as large populations (i.e., >500 patients) representing multiple diverse medical care settings. This has been the direct result of the development of multiple outcomes databases that have now amassed thousands of patients worth of data. One of the benefits of examining outcomes in large patient datasets is the ability to assess individual endpoints (e.g., cardiac death) as compared with smaller datasets that often assess combined endpoints (e.g., death, myocardial infarction, or unstable angina). New technologies for the diagnosis of coronary artery disease have contributed to the rising costs of care. In the United States and in Europe, costs of care have risen dramatically, consuming an ever-increasing amount of available resources. The overuse of diagnostic angiography often leads to unnecessary revascularization that does not lead to

    would not otherwise have been achieved if the early disease remained undetected. This publication presents a comprehensive overview of CVDs as a public health problem in developing countries, the relative role of nuclear cardiology methods within a scenario of unprecedented technology advances, and the evidence behind appropriateness recommendations. The potential expanding role of non-invasive functional imaging through the transition from diagnosis of obstructive CAD to defining the global burden of CVDs is also discussed, as well as the need for thorough training, education, and quality in nuclear cardiology practice. This report will be of interest for all medical practitioners involved in the management of CAD, including internists, cardiologists, and nuclear medicine physicians, as well as hospital administrators and health care stakeholders.

  15. Radiation doses to the staff of a nuclear cardiology department

    International Nuclear Information System (INIS)

    The last years, new radiopharmaceuticals are used in a Nuclear Medicine (NM) Department. Nowadays, Single Photon Emission Computed Tomography (SPECT) is a method of routine imaging, a fact that has required increased levels of radioactivity in certain patient examinations. The staff that is more likely to receive the greatest radiation dose in a NM Department is the technologist who deals with performance of patient examination and injection of radioactive material and the nurse who is caring for the patients visiting the Department some of which being totally helpless. The fact that each NM Dept possesses equipment with certain specifications, deals with various kind of patients, has specific design and radiation protection measures which can differ from other NM Depts and uses various examination protocols, makes essential the need to investigate the radiation doses received by each member of the staff, so as to continuously monitor doses and take protective measures if required, control less experienced staff and ensure that radiation dose levels are kept as low as possible at all times. The purpose of the current study was to evaluate radiation dose to the nuclear cardiology department staff by thermoluminescent dosemeters (TLDs) placed on the the skin at thyroid and abdominal region as well as evaluating protection measures taken currently in the Dept

    Many advances have been made in the field of nuclear cardiology in the past decade for enhancing the diagnostic and prognostic value of stress myocardial variability using SPECT technology. Gated SPECT for determining regional and global function have provided incremental diagnostic and prognostic information in the evaluation of patients with suspected or known coronary artery disease. Left ventricular ejection fraction and regional myocardial wall thickening can now be simultaneously evaluated with regional perfusion particularly with the use of the {sup 99m}Tc-labeled perfusion agents such as sestamibi and tetrofosmin. Many studies have shown that the extent and severity of stress-induced perfusion defects have incremental prognostic value over exercise electrocardiographic stress test variables alone. Patients with normal perfusions scans have <1% combined cardiac death and myocardial infarction rates per year and thus have an excellent prognosis. Diabetics are particularly benefited from stress perfusion imaging for detection of coronary artery disease and risk assessment. Diabetics have a worse prognostic than non diabetics for the same amount of hypoperfusion on stress SPECT studies. Quantitative rest perfusion imaging with {sup 201}Tl or with one of the {sup 99m}Tc-labeled imaging agents, or PET imaging with {sup 18}F-deoxyglucose can accurately distinguish viable from irreversibility injured myocardium providing useful information for identifying which patients with ischemic cardiomyopathy benefit most from coronary revascularization with a subsequent improvement in left ventricular function and enhanced survival. Finally, serial stress perfusion imaging can be employed to monitor the efficacy of medical therapy that improves endothelial function and myocardial blood flow reserve.

  18. Present and future of nuclear cardiology. Where we come from and where we are going

    International Nuclear Information System (INIS)

    The present of nuclear cardiology techniques with gated-SPECT, positron emission tomography, cardiac magnetic resonance, cardiac mIBG scintigraphy and anatomical and functional images of three-dimensional SPECT-CT fusion may be the future for some centers, a future more or less distant for others. The prediction of the ways that will be followed by the different radioisotope scans in the field of cardiology is to some extent uncertain and depends on the development of other noninvasive techniques and on the possibility of reducing the dose of irradiation, decreasing the undesirable effects of ischemia-inducing drugs, but also on the evolution of macroeconomics in different countries, and of course on the level of experience and excellence in nuclear cardiology laboratories and the confidence generated on clinical cardiologists.

  19. Nuclear cardiology practice and associated radiation doses in Europe: results of the IAEA Nuclear Cardiology Protocols Study (INCAPS) for the 27 European countries

    International Nuclear Information System (INIS)

    Nuclear cardiology is widely used to diagnose coronary artery disease and to guide patient management, but data on current practices, radiation dose-related best practices, and radiation doses are scarce. To address these issues, the IAEA conducted a worldwide study of nuclear cardiology practice. We present the European subanalysis. In March 2013, the IAEA invited laboratories across the world to document all SPECT and PET studies performed in one week. The data included age, gender, weight, radiopharmaceuticals, injected activities, camera type, positioning, hardware and software. Radiation effective dose was calculated for each patient. A quality score was defined for each laboratory as the number followed of eight predefined best practices with a bearing on radiation exposure (range of quality score 0 - 8). The participating European countries were assigned to regions (North, East, South, and West). Comparisons were performed between the four European regions and between Europe and the rest-of-the-world (RoW). Data on 2,381 European patients undergoing nuclear cardiology procedures in 102 laboratories in 27 countries were collected. A cardiac SPECT study was performed in 97.9 % of the patients, and a PET study in 2.1 %. The average effective dose of SPECT was 8.0 ± 3.4 mSv (RoW 11.4 ± 4.3 mSv; P < 0.001) and of PET was 2.6 ± 1.5 mSv (RoW 3.8 ± 2.5 mSv; P < 0.001). The mean effective doses of SPECT and PET differed between European regions (P < 0.001 and P = 0.002, respectively). The mean quality score was 6.2 ± 1.2, which was higher than the RoW score (5.0 ± 1.1; P < 0.001). Adherence to best practices did not differ significantly among the European regions (range 6 to 6.4; P = 0.73). Of the best practices, stress-only imaging and weight-adjusted dosing were the least commonly used. In Europe, the mean effective dose from nuclear cardiology is lower and the average quality score is higher than in the RoW. There is regional variation in effective dose in

    Acquisition of both stressed and rest myocardial perfusion simultaneously is possible when dual-isotope technique is used. And using this technique authors also can obtain data of myocardial perfusion and metabolism imaging with different clinical significance under the same physiological condition. The clinical application of dual-isotope in nuclear cardiology and its scatter correction was reviewed

  2. Activity and practice of nuclear cardiology in the Czech Republic, 2001

    International Nuclear Information System (INIS)

    Radionuclide myocardial perfusion imaging (MPI) has been on the rise in Europe and the USA. Details on nuclear cardiology in the Czech Republic are not available as yet, as it is impossible to obtain comprehensive data from official registers owing to different methods of reporting and data evaluation. A questionnaire concerning nuclear cardiology activity and practice in 2001 was sent to all nuclear medicine departments in the Czech Republic. All 48 departments completed the questionnaire. In 2001, 50 planar and 54 tomographic (SPET) scintillation cameras were used. The average age of the SPET cameras was 5 years (13% of SPET cameras were >8 years old). Out of the 48 centres, 39 (81%) provided a nuclear cardiology service; the total number of cardiological studies was 15,740 in 2001 (1.5 studies/1,000 population/year). The most frequently employed method was MPI (81.7%), the frequency of which had increased by 10% compared with 2000; 26 of the 39 (67%) departments reported that MPI activity was increasing. Nevertheless, the Czech Republic nuclear cardiology activity remained below the European average (2.2/1,000 population in 1994) and, particularly, below activity in the USA (15/1,000 in 1997). The activity was rather unevenly spread. Whereas two centres with >1,000 studies/year accounted for 20% of the total MPI studies, 16 of 39 (41%) departments exhibited low activity (99mTc-MIBI (60% of total MPI), followed by 201Tl (21%) and 99mTc-tetrofosmin (19%). ECG-gated SPET was employed by 20/39 (51%) centres, of which 11 (28%) performed it as a standard examination; 39% of the total MPI studies included this technique. Thirteen percent (5/39) of the departments used attenuation correction, and 69% (27/39) of the departments used a prone projection. Equilibrium radionuclide ventriculography, with 2,317 examinations (14.7%), ranked second among all nuclear cardiology methods, followed by first-pass angiocardiography (406 studies, 2.6%) and 18F-FDG (163 studies, 1

  3. Clinical use of nuclear cardiology in the assessment of heart failure

    International Nuclear Information System (INIS)

    Nuclear cardiology is the most commonly performed non-invasive cardiac imaging test in patients with heart failure, and it plays an important role in their assessment and management. Quantitative gated single positron emission computed tomography is used to assess quantitatively cardiac volume, left ventricular ejection fraction, stroke volume, and cardiac diastolic function. Resting and stress myocardial perfusion imaging can not only identify nonischemic heart failure and ischemic heart failure, but also demonstrate myocardial viability. Diastolic heart failure also termed as heart failure with a preserved left ventricular ejection fraction is readily identified by nuclear cardiology techniques and can accurately be estimated by peak filling rate and time to peak filling rate. With newer techniques such as three-dimensional, quantitative gated single positron emission computed tomography can assess movement of the left ventricle, and wall thickening evaluation aids its assessment. Myocardial perfusion imaging is also commonly used to identify candidates for implantable cardiac defibrillator and cardiac resynchronization therapies. Neurotransmitter imaging using 123I-metaiodobenzylguanidine offers prognostic information in patients with heart failure. Metabolism and function in the heart are closely related, and energy substrate metabolism is a potential target of medical therapies to improve cardiac function in patients with heart failure. Cardiac metabolic imaging using 123I-15-(p-iodophenyl) 3-R, S-methylpentadecacoic acid is a commonly used tracer in clinical studies to diagnose metabolic heart failure. Nuclear cardiology tests, including neurotransmitter imaging and metabolic imaging, are now easily preformed with new tracers to improve heart failure diagnosis. Nuclear cardiology techniques contribute significantly to identifying patients with heart failure and to guiding their management decisions. (authors)

  4. Nuclear cardiological investigations in patients classified as physically disabled following myocardial infarction

    International Nuclear Information System (INIS)

    110 patients classified as physically disabled as a consequence of myocardial infarction were reinvestigated by means of nuclear cardiological methods. Resting 201Tl perfusion scintigraphy showed a normal distribution of radioactivity, while radionuclide ventriculography revealed a normal left ventricular ejection fraction and a normokinetic left ventricle in 20 patients. The investigation of a further 19 patients demonstrated only minimal pathological changes. The results in 34 patients revealed severe myocardial damage, and in a further 19 cases the development of left ventricular aneurysm. The results clearly show the value of 201Tl scintigraphy and radionuclide ventriculography in assessments of the degree of physical disability after myocardial infarction. (author) 15 refs.; 3 tabs

  5. British Energy - nuclear power in the private sector

    International Nuclear Information System (INIS)

    The first four months of the operation of British Energy as a privatised nuclear utility are briefly reviewed. Operational and financial performance have been good as exemplified by the figures for power output and financial return. Freedom from government control means that the options open to the company are much wider but the need to meet the expectations of shareholders is a major consideration. Added to this, the competitive nature of the electricity industry means that the cost reduction is important, though this cannot be at the expense of safety. Shareholder expectations make the funding of new nuclear power stations unrealistic at present. Increasingly, however, markets are opening up in the maintenance of existing plant and the decommissioning of older plant. The British Energy Group also has considerable expertise in the design, operation and management of power stations and of acting in a competitive energy market that could be exported. British Energy's International Division is in place to develop this potential. (UK)

    The use of myocardial perfusion imaging has seen a tremendous growth during the last decade and has become the most commonly used non-invasive imaging tool for risk stratification in patients with suspected and known coronary artery disease. Adherence to radiation safety best practices varied significantly between laboratories but the possibility to use the new cameras in nuclear cardiology can reduce dramatically the radiation dose without losing accuracy. Moreover, the physical characteristics of ultrafast technology could be able to open new doors for the evaluation of old parameters, changing the impact of nuclear cardiology in the diagnostic strategies.

  7. Diagnostic radiology and nuclear cardiology: their use in assessment of equine cardiovascular disease

    International Nuclear Information System (INIS)

    Survey thoracic radiography, although limited by physical considerations in the adult horse, can supply clinically useful information about changes in cardiac size and function. The radiographic features of cardiomegaly, altered pulmonary circulation, pulmonary edema, and pleural effusion as manifested in the horse are discussed. Nuclear cardiology can be performed in the standing horse. The initial transit of a radioactive tracer through the central circulation provides information about cardiac chamber size, efficiency of ventricular contraction, valvular competence, and presence of intracardiac or extracardiac shunts. Computer analysis of similar studies allows quantitation of several useful cardiac parameters including ventricular ejection fraction and shunt size (QP/QS). Gated blood pool nuclear studies are better suited to evaluate cardiac response to stress but are difficult to perform in the conscious horse with standard imaging equipment

  9. Protest movements against nuclear energy and the British state

    International Nuclear Information System (INIS)

    Two main aspects which explain the comparative weakness of the British anti-nuclear movement are identified. First, debate over nuclear energy has been conducted within a public enquiry framework and second there has been a lack of stimuli for opposition to emerge and develop. The main part of this paper analyses the political conflict over nuclear energy from 1974 to 1989 divided into four phases. Phase one (1974-1978) saw the emergence of nuclear power as a political issue and the early encounters between pro and anti-nuclear forces at the Windscale Inquiry in 1977. Phase two (1978-1981) saw the rise of a more radical anti-nuclear lobby as a national movement. Phase three (1982-1987) was characterized by the Sizewell-B inquiry. Phase four saw a major crisis in the British nuclear industry not from anti-nuclear protest but from the Governments privatisation policy. The paper concludes with a discussion of the value of the policy style concept for an explanation of the role of the state in the nuclear conflict. (UK)

  10. Use of nuclear cardiology examinations to predict slow recovery from takotsubo cardiomyopathy

    International Nuclear Information System (INIS)

    Takotsubo cardiomyopathy is generally believed to have a good prognosis. However, there are considerable differences among individuals in the severity of abnormal left ventricular wall motion and in the time required for normalization. We investigated the usefulness of nuclear cardiology examinations for the differentiation of severe cases of takotsubo cardiomyopathy, which are associated with long-term wall motion abnormality. The participants were 18 patients diagnosed with takotsubo cardiomyopathy. Assessment was performed using rest TL-201 or technetium-99m sestamibi myocardial perfusion single positron emission computed tomography (SPECT) (MPS); myocardial fatty acid metabolism was evaluated by using I-123 beta-methyl-iodophenyl-pentadecanoic acid (BMIPP). A polar map was constructed from SPECT short-axis views, and was divided concentrically into 3 regions: the apical, intermediate, and base areas. The ratio of the apex to the intermedia, using mean uptake percentages, was defined as the apical uptake ratio (AUR). Participants in whom local wall motion normalized in ≤28 days or >28 days, as determined by echocardiography, were grouped into the normal recovery group (13 patients) or the slow recovery group (5 patients), respectively. AUR in MPS was 0.96±0.04 in the normal recovery group and 0.80±0.05 in the slow recovery group (p=0.008). Similarly, AUR in BMIPP significantly differed: 0.81±0.03 in the normal recovery group and 0.67±0.03 in the slow recovery group (p=0.014). The use of nuclear cardiology examinations to evaluate local uptake ratio in the apex is useful for identifying severe takotsubo cardiomyopathy, in which abnormal local wall motion may persist.

  11. Application of a visualization method of image data base in nuclear cardiology

    International Nuclear Information System (INIS)

    Medical imaging is undoubtedly one of the medical branches which benefited at most by the offsprings of computer science development. We present here a visualization software of image data base, making use of the last innovations in the field of multimedia application. The objective of such a software is to provide a reference tool for a given medical specialty offering at the same time, a high quality iconography, a rigorous content of the comments and the matching of graphical interfaces. Applied to nuclear cardiology and implanted on CD ROM, it contains a given number of clinical cases (around 150) which sweep quasi-exhaustively the subject. Each case centered around scintigraphic examination (myocardial tomographs, ventriculographs, SPECT, etc) makes available 'static' pictures (series of cross sections, planispheric images, ECG), animated cartoons (synchronized series, 3D visualization, etc) and also the clinical history of the patient and the records of complementary examinations (coronary-graphic, for instance). Being independent of the image data base which it visualizes, our software is easily applicable to other nuclear medicine specialties (neurology, renal exploration) and also to other modalities. It is multilingual already (French and English) and soon will be supplemented by a code dedicated to knowledge assessment intended to be an efficient tool in education and continuous formation. A Macintosh version will be soon obtainable and a demonstration diskette is free available on request

  12. British Nuclear Fuels PLC: report and accounts 1989-90

    International Nuclear Information System (INIS)

    Members of the Energy Select Committee put questions to representatives of British Nuclear Fuels PLC (BNFL) about the annual report and accounts 1989-90. Questions concerned the late publication of the accounts, BNFLs role in the downfall of the nuclear privatisation, government assistance to the nuclear industry, the price BNFL charges for fuel reprocessing and the process of laser isotope separation of uranium. The committee also asked about the rate of return in BNFL's assets as a percentage, Sellafield's potential as a site for a deep repository for radioactive wastes and the 6000 boreholes that MREX will drill at Sellafield. The commercial case for reprocessing is made. Feasibility studies for possible new reactions at Sellafield and Chapel Cross have been carried out. On the whole the Energy Committee were satisfied with the replies from BNFL. (UK)

  13. Reconstruction of British Nuclear Fuel's Drigg marine outfall

    International Nuclear Information System (INIS)

    In 1985 the House of Commons Environment Committee expressed reservations over some of the waste-management procedures followed by British Nuclear Fuels Ltd at their Drigg low-level radioactive waste disposal facility near Sellafield in Cumbria. These reservations prompted the company to implement a Pound 20 million programme of improvements aimed at maximizing site usage, reducing trench leachate arisings and redirecting to the Irish Sea. This paper provides information and test results associated with design considerations and initial dilution testing, respectively, of a computer-controlled long sea outfall system designed to discharge leachate to the Irish Sea. Information is also provided on difficulties experienced during construction of the outfall. (Author)

  14. Privatization and culture change: British Nuclear Fuels case study

    International Nuclear Information System (INIS)

    This paper describes and explains the process of organizational change experienced by British Nuclear Fuels (BNFL) during the late 1980s. BNFL went through a major transformation in management values and practices to survive in the new business environment characterized by government deregulation and fiercer global market competition. The paper describes both the historical and the prevailing management behaviour as well as the strategy utilized by BNFL's top management in their change process. The key factor in the process of change seems to lie in top management commitment and a fully integrated set of actions involving different sub-systems of the organization. (author)

  15. British nuclear power: protest and legitimation 1945 - 1980

    International Nuclear Information System (INIS)

    This thesis traces the development of British civil nuclear power policy between 1945 and 1982. Throughout particular attention is paid to the methods of legitimation which have been used to justify this policy in the public arena. By tracing this legitimation process, and public responses to it, the modern anti nuclear movement and crisis of public acceptability are placed within an historical context. It is argued that public concern and disquiet have always required the active legitimation of nuclear policy from the inception of the technology. The initial base of this legitimation was largely symbolic and associated nuclear power with the future of civilisation and a second of Elizabethan splendour for Britain. Symbolic legitimacy was underpinned by the twin pillars of expert hegemony and political authority. As these became increasingly prominent due to internal disputes within the industry secrecy was applied as a means of preserving legitimacy. Having tried conventional avenues of opposition the anti nuclear movement then embarked upon a campaign of direct action. The links between this campaign and the pervasive sense of public unease which had always existed are explored. It is argued here that the anti nuclear movement produces and sustains a cogent critique of nuclear power. Campaigning around this critique wins the movement increasing legitimacy as its arguments are increasingly accepted. (author)

  17. The usefulness of the nuclear cardiology in the cellular implant in patients with severe myocardial damage

    International Nuclear Information System (INIS)

    The recent therapeutic advances as the cellular implant as well as those different protocols of image acquisition in the field of the Nuclear Cardiology its have allowed that the patient with severe myocardial damage and without some possibility of revascularization is benefited with these advances. Doubtless the Tl-201 par excellence has an important paper for standardize the more appropriate therapeutic behavior for the heart attack patient; reason by this investigation protocol was developed. The objective of the study was to identify the heart attack regions without viable tissue with SPECT in patient with important myocardial damage without some possibility of traditional revascularization; for the 'Stem cell' cellular implantation therapy. The methodology it was carried out by a study of myocardial perfusion in 10 patients with important myocardial damage previous cellular implants, with PICANUC/ SPECT methodology and using a software (Emory Tool Box) for the image processing validated by the University of Emory Atlanta GA; and using as tracer the Tl - 201 to identify the heart attack regions without presence of viable tissue with an analysis model of 17 segments standardized for the left ventricle; qualifying this way the myocardial perfusion in: 0 (normal), 1 (light), 2 (moderate), 3 (severe), 4 (absent) and x (bad technique). The conclusions were that the SPECT study with PICANUC methodology with Tl-201 is safe and effective for the precise localization for the cellular implantation via direct intra myocardial. (Author)

  18. Contributions of nuclear cardiology to prognosis and risk stratification in coronary artery disease

    International Nuclear Information System (INIS)

    Myocardial perfusion imaging in patients with suspected or known coronary artery disease and stable symptoms enables not only accurate diagnosis of disease but also entails prognostic value. Myocardial perfusion SPECT contributes to assessment of future cardiac events independently of other clinical parameters. A normal stress myocardial perfusion scan is associated with a favorable prognosis in all pre-test risk subsets similar to that of the general population independent of history, symptoms, and exercise electrocardiography test variables. Cardiac risk and benefit from invasive therapeutic strategies increase in relation to the severity of the abnormality of perfusion and function assessed by gated myocardial perfusion SPECT. Thus, stress myocardial perfusion imaging may serve as a gatekeeper for referral to coronary angiography enabling effective risk stratification in patients with suspected or documented coronary artery disease. In severe coronary artery disease accompanied by left ventricular dysfunction preoperative prediction of reversibility of functional impairment and improvement in survival after revascularization can be achieved by viability testing using nuclear cardiology. Absence of viability is associated with no significant difference in functional and survival outcomes, irrespective of treatment strategy. Therefore, unnecessary revascularization can be avoided in cases with absent evidence of viability. (orig.)

  19. British Nuclear Fuels plc: report and accounts 1987-88

    International Nuclear Information System (INIS)

    The Energy Committee has considered the report and accounts of BNFL (British Nuclear Fuels PLC) for the year 1987-88. The report looks at BNFL as a government owned PLC - its activities and financial performance. Various questions are raised about the underlying financial position justifying the optimism portrayed in the report and accounts. The impact of cost-plus contracts on UK customers is examined. The economics of THORP (Thermal Oxide Reprocessing Plant) are also examined especially as the escalation in the cost of constructing THORP means that a substantial loss will be made in the reprocessing of waste for which contracts were signed in the late 1960s or early 1970s. The main conclusions of the report are summarized. One of these is that the UK must be cautious about becoming a repository of foreign nuclear waste. Other specific recommendations are made - some about the decommissioning of BNFL plant. (UK)

  20. British Nuclear Fuels PLC: report and accounts 1988-89

    International Nuclear Information System (INIS)

    This item covers a meeting held between members of the United Kingdom government's energy committee and representatives of British Nuclear Fuels (BNFL) to discuss their Annual Report and Accounts for the year 1988-89. The committee explored the reasons for escalating predictions of the costs of nuclear power and why decommissioning costs are so difficult to estimate accurately so as to include them in cost per kilowatt hour of generated electricity. The relationship between BNFL and the Ministry of Defence (MoD) was explored, as was the MoD's relationship with the United States Department of Defense. BNFL's financial position should improve when the thermal oxide reprocessing plant at Sellafield becomes operational, and the Chapelcross and Calder Hall reactors may contribute income from electricity generation.

    The efforts for a broad application of the appropriate use criteria to reduce inappropriate nuclear stress testing have frequently been unsuccessful and the reported rates of inappropriateness have varied widely between studies. We sought to analyze the criteria of clinical appropriateness of a cohort of consecutive patients referred to our nuclear cardiology laboratory to perform stress myocardial perfusion imaging (MPI) and to assess the relationships between test appropriateness and the evaluation of ischaemia. A cohort of 251 consecutive patients, admitted to our Institute from January to March 2015, who underwent stress/rest MPI on a dedicated cardiac camera equipped with cadmium-zinc-telluride detectors, was selected. The level of clinical appropriateness of each MPI test was categorized in each patient according to the AUC criteria. According to the accepted criteria, the majority of the MPI stress-tests could be classified as clinically appropriate (218 of 251, 87 % of the tests), while only 16 (6 %) and 17 (7 %) resulted of uncertain appropriateness or clearly inappropriate, respectively. Of the 251 appropriate tests, 22 (10 %), 65 (30 %), and 131 (60 %) showed the presence of a mild (SDS < 4), moderate (4 ≥ SDS < 7), and severe (SDS ≥ 7) ischemic burden, respectively, while none of the inappropriate test showed moderate-to-severe ischaemia (P < 0.001 for comparisons). The rate of inappropriate MPI tests is considerably low in a high-volume laboratory. Appropriate and inappropriate studies identify patients at high and low probability of significant ischemia, respectively, providing insights on the effects of the level of appropriateness on stress-test results.

    International Nuclear Information System (INIS)

    Full text: Introduction: Traditional Nuclear Medicine training includes seminars, guided practices and self learning modules (continuing education and internet-based). We have developed recently a combination of training, quality control and active clinical research, with postgraduate nuclear medicine residents and pre-graduate technology students. Goal: a) to assess the reproducibility of diverse techniques, among staff specialists and residents; and b) software application quality control. This, also in order to accomplish international parameters, mainly in nuclear cardiology training. Methodology and Results: Four main cardiovascular subjects were selected: A) Reproducibility in Lung V/Q Scans Interpretation: 401 studies from 382 patients with a possible pulmonary embolism were analyzed retrospectively; a blind lecture was performed by 6 independent observers with different experience level. Interpretation was based on individual experience and revised PIOPED criteria. Original reports included 27.2% high probability and 67.3% low probability. Interobserver agreement range was: 73-86% and correlation with original report: 74-82%. Excellent interobserver concordance and kappa was found, higher in experienced observers. B) Perfusion SPECT in Coronary Artery Disease (CAD): 60 cases with recent myocardial infarction with successful thrombolysis were blindly interpreted by 2 independent specialists and also by 5 in-training observers from different universities. Excellent interobserver agreement was obtained by specialists for normal/abnormal perfusion and wall motion (98.3% and 93.3%, respectively). Agreement between perfusion and wall motion was adequate, as well as assigned artery analysis. There was good correlation interpreting myocardial perfusion SPECT at both centers, with better adjustment in more experienced observers. Currently, we are developing another study comparing interobserver reproducibility for exercise electrocardiogram and perfusion images

    1979-01-01

    Education of medical students in cardiology requires access to patients having a variety of different forms of heart disease. But bringing together student, instructor and patient is a difficult and expensive process that does not benefit the patient. An alternate approach is substitution of a lifelike mannequin capable of simulating many conditions of heart disease. The mannequin pictured below, together with a related information display, is an advanced medical training system whose development benefited from NASA visual display technology and consultative input from NASA's Kennedy Space Center. The mannequin system represents more than 10 years of development effort by Dr. Michael S. Gordon, professor of cardiology at the University of Miami (Florida) School of Medicine.

  6. Nuclear power, climate change and energy security: Exploring British public attitudes

    International Nuclear Information System (INIS)

    Public attitudes towards nuclear power in the UK have historically been deeply divided, but as concern about climate change and energy security has exerted an increasing influence on British energy policy, nuclear power has been reframed as a low-carbon technology. Previous research has suggested that a significant proportion of people may 'reluctantly accept' nuclear power as a means of addressing the greater threat of climate change. Drawing on the results of a national British survey (n=1822), the current study found that attitudes towards nuclear remain divided, with only a minority expressing unconditional acceptance. In general, people who expressed greater concern about climate change and energy security and possessed higher environmental values were less likely to favour nuclear power. However, when nuclear power was given an explicit 'reluctant acceptance' framing - allowing people to express their dislike for nuclear power alongside their conditional support - concerns about climate change and energy security became positive predictors of support for nuclear power. These findings suggest that concern about climate change and energy security will only increase acceptance of nuclear power under limited circumstances-specifically once other (preferred) options have been exhausted. - Highlights: → We report data from 2005 to 2010 of British attitudes towards nuclear power and climate change. → Changes in attitudes over the time period were relatively modest. → British population remained relatively divided on nuclear power in 2010. → Concern about climate change was negatively related to evaluations of nuclear power. → Different framings of the issue alter the balance of support for nuclear power.

  9. Preparation for Fuel Storage Pond Clean Up British Nuclear Group Sellafield Site

    International Nuclear Information System (INIS)

    The Legacy Ponds at Sellafield represent one of the biggest challenges in the civil nuclear clean up portfolio in the UK. In June 2002 British Nuclear Group contracted with the ACKtiv Nuclear Joint Venture to progress the risk mitigation, asset restoration and the early enabling works associated with preparation for clean up. The ACKtiv Nuclear JV was formed from three major engineering and construction companies in the UK - Aker Kvaerner, Carillion and Atkins. This paper describes some of the technical, and safety challenges the project successfully overcame in reducing some of the risks that the Legacy Pond represented and the preparation for clean up.

    2001-12-01

    This year 2001 has been very rich in innovations and in works-in-progress in the field of cardiac imaging. In nuclear cardiology, this year has been mainly impressed by a large number of studies concerning 'gated SPECT' which allows the simultaneous analysis of the perfusion and of the contraction of the left ventricle. The clinical contribution of this technique is quite significant in any of the fields of use of the conventional tomo-scintigraphy such as the screening of the coronary disease, the evaluation of its prognosis or the evaluation of the viability. Innovation has also concerned the field of the radio-tracers, with studies concerning some very promising tracers of the apoptosis or of the cellular hypoxia. At last, various works have been carried out on the gamma-cameras, particularly to make them suitable for imaging of tracers used in positron emission tomography (PET). This should allow to spread to any of the nuclear medicine centers the use of FDG imaging which is the golden standard for myocardial viability assessment. About MRI, a lot of studies have been performed about sequences using gadolinium as a vascular contrast agent, to identify and to localize the infarction sequelae, even when limited to sub-endocardium. Probably the most dramatic technical innovations concerned the development of methods enhancing the recorded signal (SENSE) and the design of real-time imaging sequences, without apnea and without ECG gating. But, as every year, important advances have also been registered in angio-MR of the coronary vessels, as in the myocardial perfusion analysis using sequences without the requirement of contrast agent injection.

  13. The leakage of radioactive liquor into the ground, British Nuclear Fuels Ltd., Windscale, 15 March 1979

    International Nuclear Information System (INIS)

    On 15 March 1979 radioactive liquor of recent origin was confirmed to be present in the ground adjacent to the Buffer Storage Plant Building B212 at the Windscale and Calder Works in Cumbria of British Nuclear Fuels Ltd. BNFL's initial investigations to identify the source of this leakage were closely followed by an investigation carried out by HM Nuclear Installations Inspectorate into how control of the radioactive liquor came to be lost and whether there had been any breaches of licence conditions or of the requirements of the Health and Safety at Work etc Act 1974. This report presents the findings of these investigations and concludes by outlining the actions taken and the requirements placed on British Nuclear Fuels Ltd. (author)

    近十年来,负荷单光子发射计算机断层成像心肌灌注显像(SPECT MPI)已成为可疑或已知冠心病(CAD)患者诊断和处理最常用的负荷显像技术,并已得到众多相关临床指南的充分肯定,推荐将SPECT MPI作为冠状动脉造影(CAG)的“守门人”,减少不必要的造影.然而,我国的核心脏病学起步较晚,导致部分临床医师对核心脏病学的认识不足.在选择冠状动脉造影、CT冠状动脉造影(CTCA)等技术诊断和处理CAD时,常常存在“误区”,以致出现过度应用的趋势.本文将重点介绍核心脏病学目前的作用,简要介绍最近核心脏病学在心脏混合显像及分子显像方面的进展,以促进核心脏病学在我国的合理应用.%For the past decade, the diagnosis and treatment of coronary artery disease (CAD) has shifted from the traditional model by evaluating coronary artery stenosis with morphological imaging methods to a novel model by focusing on the detection of ischemia for risk stratification. The myocardial perfusion imaging (MPI) using stress single photon emission computed tomography (SPECT) has become the most commonly used stress imaging technique for the diagnosis and treatment of patients with suspected or known CAD. It has got strong supports, including those of the American College of Cardiology, American Heart Association, American Society of Nuclear Cardiology (ACC/AHA/ASNC) and other numerous clinical guidelines. They all stressed that the SPECT MPI is recommended to be used as the "gate keeper" to coronary angiography in order to prevent unnecessary intervention test and save the cost. However, in China the introduction and application of nuclear cardiology was late and highly unbalanced. This leads to the lack of understanding of nuclear cardiology in some clinicians, and there often is misunderstanding on correct selection of coronary angiography, cardiac CT, CT coronary angiography and others for diagnosis and treatment of CAD

  15. The British Nuclear Industry Forum's public affairs campaign

    International Nuclear Information System (INIS)

    Full text: In March 1999, BNIF launched a public affairs Campaign with the objective of influencing the views of opinion formers - particularly in the political field - about the case for nuclear energy as a long-term, sustainable component of the UK's energy mix. The Campaign was launched to BNIF's 70 member companies under the slogan, Profiting through Partnership - By Changing the Climate of Opinion. That slogan was chosen to emphasise a key feature of the Campaign approach, which is the importance of an industry speaking collectively with one voice, but with each individual company actively playing its part by spreading the industry's messages to their own local and regional audiences - Members of Parliament, local politicians, local media - to build a groundswell of support for the eventual renewal of nuclear energy in the UK. Our aim was to place the prospect of a new nuclear power station firmly on the political agenda during the lifetime of the next Parliament - that is, in the period 2002-2007. The Campaign was launched at a time when a few encouraging signs were emerging of a growing recognition in Government, Parliament, and in academic and scientific circles that nuclear energy has an important role to play in meeting the energy and environmental challenges of the 21st century. The challenge, in particular, of climate change and the UK Government's commitment to reduce greenhouse gas emissions undertaken at Kyoto and in its election manifesto, gave the industry a strong, positive issue on which to campaign. However, we fully recognised that to make a convincing case for nuclear energy we would also have to address the issues of concern and doubt in the minds of the public and politicians - economic competitiveness, waste management, transport and decommissioning. During the year, BNIF produced a range of Campaign materials, made submissions to several Government and other inquiries and consultations, organised events, meetings and discussions, all with

  16. Defense policy and public opinion: The British campaign for nuclear disarmament, 1945-1985

    Energy Technology Data Exchange (ETDEWEB)

    Dackiw, O.A.

    1988-01-01

    This study is concerned with the rise and fall of anti-nuclear activism in Great Britain. Although anti-nuclear activists do not represent the majority of British public views on defense, their very vocal and highly visible activity can have major disruptive effects of US foreign policy and the North Atlantic Treaty Organization. Moreover, insights into the anti-nuclear movement in Britain offer a standing point for a comparative assessment of analogous campaigns throughout Europe. In exploring this topic, the dissertation examines three key questions. First, what are the direct causes of cyclical anti-nuclear activism in Britain Second, are particular types of deployment instrinsically more provocative, and therefore, more politically exploitable than others Third, what are the particular socio-psychological factors associated with nuclear systems which Labour Party activists are able to manipulate In answering these questions, this study concentrates on one central hypothesis: that cycles of British nuclear activism are catalyzed by the deployment of foreign systems which evoke (a) special feelings of subordination in a hegemonic Anglo-US relationship, and (b) deep-seated symbolic fears of the apocalypse.

  17. Mr and Mrs Merlin - v. - British Nuclear Fuels PLC

    International Nuclear Information System (INIS)

    The Merlin case is of interest for several reasons. The judge had to deal with the question whether the mere existence of radioactive particles in a dwelling house would lead to compensatable economic loss even if, incontestably, there had not been any damage to health or property. The legal basis for a possible claim was the Nuclear Installations Act 1965, the UK Statute implementing the Paris Convention. A judge thus had to clarify for the first time what is to be understood under 'damage to or loss of any property' within the meaning of the Paris Convention (section 3). Remarkable is also the ratio of the amount of the claim to the costs the defense had. Claimed were some pound 30,000 economic loss; the defense costs amounted to pound 3 millions. Defendant accepted this because of the effect of judicial precedent, despite there being no chance of costs being reimbursed by dismissed plaintiff. (orig./HSCH)

    1991-01-01

    An excess of childhood leukaemia has been seen near some British nuclear installations, especially near the Sellafield reprocessing plant. The same result was found in a more general study including a large number of nuclear sites. Similar studies made in USA, Canada and France have been negative. Moreover, epidemiological studies made in England have discovered other childhood leukaemia clusters in areas far from nuclear facilities, and especially near potential sites of nuclear installations. Several explanations are suggested but no definite conclusion is yet possible. Doses from radioactive releases seem to be too low to account for the additional deaths from leukaemia by environmental contamination. A virus activation, which might be associated with population influx into rural isolated areas, has been considered. The hypothesis of genetic mutation induced by ionising radiation in the fathers of children with leukaemia has been made because a higher risk of leukaemia was observed for children of fathers employed at Sellafield. No firm conclusion is possible considering the small number of observed cases and the lack of excess leukaemias in the offspring of Hiroshima and Nagasaki survivors. The possibility of internal contamination, chemicals or even radon is discussed as other causes. Studies in progress might allow to find an answer to the problem of leukaemia in the vicinity of British nuclear installations.

  19. Approach of British Nuclear Fuels to managing ageing

    International Nuclear Information System (INIS)

    The approach taken by BNFL to managing ageing is developed at the design stage and builds upon experience gained through designing, building, operating and decommissioning nuclear facilities since 1947. Much of the current philosophy was developed during the design and construction of the Thermal Oxide Reprocessing Plant (THORP). The process of managing ageing encompasses all the phases of the facility's life; that is, design, operation and decommissioning. Underlying all these phases is the input from the results of research and development and plant inspection activities. Plant ageing is managed by a policy of understanding the degradation mechanisms as far as possible and, from that knowledge, targeting for particular attention plants considered as vulnerable or for which we are uncertain of our understanding of the degradation processes; for example, THORP receipt and storage LWR storage racks have been fabricated from 304L stainless steel. In their storage environment, deionized water, the worst case measured corrosion rate for such steels is 0.03 mm/a. Given that the minimum material thickness used is 20 mm, corrosion over the design life is negligible and therefore there are no prescribed monitoring or maintenance requirements. Plant inspection policy was first developed for THORP, where targeted programmes of inspection are established. Inspection may be limited to visual inspection or may involve quantitative non-destructive testing such as ultrasonics, and in certain areas, such as dissolvers, on-line thickness monitors have been installed to facilitate the process. The programmes are updated as the actual plant operating conditions are better known and understood; therefore, for example, an SSC found to be operating at higher temperatures than originally planned or carrying a higher burden of corrodents may become targeted for inspection, whereas SSCs perceived to be benign may have inspection frequencies reduced. Similar policies are being developed for

  20. Preparation for commissioning of nuclear plant with reference to British Nuclear Fuels Plc fuel handling plant project

    International Nuclear Information System (INIS)

    The new Fuel Handing Plant at British Nuclear Fuels Sellafield is part of a Pound 550M complex which provides facilities for the receipt, storage and mechanical preparation of both magnox and A.G.R. fuel. The plant is very large and complex with considerable use of computer based process control systems, providing for physical and nuclear safety. The preparation of such plant for ''active'' commissioning necessitates a great many physical checks and technical evaluations in support of its safety case. This paper describes arrangements for plant commissioning checks, against the regulatory framework and explains the physical preparations necessary for their timely accomplishment. (author)

  1. Department of Energy: monitoring and control of British Nuclear Fuels plc

    International Nuclear Information System (INIS)

    British Nuclear Fuels plc (BNFL) was set up in 1971 to take over the nuclear fuel production and reprocessing activities of the United Kingdom Atomic Energy Authority with the Department of Energy (as majority shareholder) being responsible for the monitoring and control of BNFL's activities. BNFL's activities include the production of nuclear fuel, uranium enrichment, and the transportation and reprocessing of spent fuel. Its major capital investment includes the construction of the Thermal Oxide Reprocessing Plant (THORP) due for completion in 1992. This study examined the effectiveness of the Department's arrangements for monitoring and control and for safeguarding the Government's investment in the company, the arrangements for examining BNFL's capital investment programme and the extent to which the Department's main aims have been achieved. The examination was restricted to the financial performance. The National Audit Office found evidence to suggest that BNFL's financial performance has not kept pace with the general performance level of British Industry. Future success and performance will depend on the success of the THORP plant. (U.K.)

  2. De-regulated electric power markets and operating nuclear power plants: the case of British energy

    International Nuclear Information System (INIS)

    One issue addressed in almost all electric power restructuring/de-regulation plans in both the United States (US) and the United Kingdom (UK) was the recovery of operating nuclear power plant's spent fuel disposal costs and the expenditures to decommission the units when they are retired. Prior to restructuring, in theory at least, in both countries, electricity consumers were paying for the back end costs from operating nuclear power plants. Moreover, in virtually all cases in the US, states included special provisions to insure that consumers would continue to do so after power markets were de-regulated. When power markets in the UK were initially restructured/de-regulated and nuclear power privatized, the shareholders of British Energy (BE) were initially responsible for these costs. However, after electricity prices fell and BE collapsed, the British government shifted many of the costs to future taxpayers, as much as a century forward. If this was not done, the book value of BE's equity would have been about -3.5 billion pounds. That is, BE's liabilities would have been about -3.5 billion pounds greater than their assets. It is difficult to see how BE could remain viable under such circumstances

    The report examines in detail the British atomic tests conducted in Australia between 1952 and 1963. The background to the Australian involvement, nuclear weapons, radiation, radiological protection and radiation protection standards are discussed. For each trial the report looks at the choice of the testing site, the criteria for safe firing, fallout monitoring and the safety of aborigines and servicemen. The second volume covers the minor trials carried out at Emu and Maralinga and considers the security aspects of the tests. The state of the test sites and future management of the Range is discussed

  4. Second report on British nuclear weapons safety: a response to the Oxburgh report

    International Nuclear Information System (INIS)

    The Ministry of Defence's (MoD) report on nuclear weapons safety by Professor Sir Ronald Oxburgh fails to examine fundamental issues raised by the US Drell report concerning Trident, Chevaline and WE177. There has been a failure to make proper diagnosis, and where diagnosis has been made to offer appropriate treatment. Oxburgh states that he cannot give a definitive view on whether the Trident warhead meets the crucial ''one-point safety'' standard; that nuclear weapons are inherently hazardous; that they can produce accidental detonations and the release of plutonium; that contractorisation of Aldermaston may erode safety standards; that management must be improved; and that there is no complete record of nuclear accidents. This British American Security Information Council (BASIC) report asserts that the publicly available evidence indicates that all three British nuclear weapons could produce accidental nuclear detonations or the dispersal of plutonium as a result of fire or shock or both. Such accidents could occur, for example, during a road accident with a petrochemical truck, a submarine fire, a submarine loading accident or in an aircraft crash. Oxburgh states that WE177 and Chevaline are one-point safe, although it appears that the MoD have only used tests which Drell regarded as inferior and misleading. He also states that ''a major concern'' is the inability to be able to analyze the safety of the whole Trident system but no solution is offered. The Oxburgh report does not address the problem of fire when discussing the hazards associated with missiles and nuclear weapons. This was the central point of Drell's concerns about Trident. Oxburgh does not examine the problems and alternatives associated with the lack of safety features in the Trident warhead and its proximity to explosive fuel in the missile, nor did he examine the procedures for accident response even though these are of concern to many local authorities.

The European Association of Nuclear Medicine (EANM), the European Society of Cardiac Radiology (ESCR) and the European Council of Nuclear Cardiology (ECNC) in this paper want to present a position statement of the institutions on the current roles of SPECT/CT and PET/CT hybrid cardiac imaging in patients...

  6. Present and future of clinical cardiovascular PET imaging in Europe - a position statement by the European Council of Nuclear Cardiology (ECNC)

    International Nuclear Information System (INIS)

    This position statement was prepared by the European Council of Nuclear Cardiology and summarises the current and future potential of PET as a clinical cardiovascular diagnostic imaging tool. The first section describes how methodological developments have positively influenced the transition of PET from a research tool towards a clinical diagnostic test. In the second section, evidence in support of its superior diagnostic accuracy, its value to guide decision making and to predict outcome and its cost effectiveness is summarised. The third section finally outlines new PET-based approaches and concepts, which will likely influence clinical cardiovascular medicine in the future. The notion that integration of cardiac PET into healthcare systems and disease management algorithms will advance quality of care is increasingly supported by the literature highlighted in this statement.

  7. Renewal of a nuclear power station using the nuclear power station. Proposal to the energy policy by British Energy, Co

    International Nuclear Information System (INIS)

    British Energy, Co. (BE) carried out a proposal containing the titled content on review of energy policy promoted by the English Government. At present, in England, as about one fourth of total power generation is supplied by nuclear power generation, because of no construction plan of a new nuclear power station, no unit will be operated on 2025 except the Sizewell Nuclear Power Station. Now, BE proposed that from a viewpoint of energy security in England and the Earth environment, shares of power generation on 2025 should be 15 % in coal heat, 40 % in gas heat, 20 % in reusable energy, and 25 % in nuclear power generations. Therefore, it is said that about ten units of 1.0 to 1.2 million kW output of nuclear power station must be constructed and begun to operate from 2010 to 2025. However, as at present power market price in England, new construction of a nuclear power station will not be payable, together with proposing a carbon-free obligation system where a part of power is obtained from a source without emission of CO2, BE claims to have a negotiation to exempt disposal responsibility on used fuels and radioactive wastes of neck in BE's yield to enforce equity finance ability of BE. Here was introduced on outlines of the proposal. (G.K.)

  8. The report of the Royal Commission into British nuclear tests in Australia

    International Nuclear Information System (INIS)

    The conclusions and recommendations of the Royal commission into British nuclear tests conducted in Australia between 1952 and 1963 are presented. The recommendations include that action should be commenced immediately to effect a clean-up of Maralinga and Emu so that they are fit for unrestricted habitation by the traditional Aboriginal owners as soon as practicable; all costs of any future clean-ups at Maralinga, Emu and the Monte Bello Islands should be borne by the United Kingdom Government; a Maralinga Commission should be established to determine the clean-up criteria, oversee the clean-up and co-ordinate all future Range management; the Australian government should make compensation to those persons and descendants of those persons who have a traditional interest in sites at the former Maralinga Prohibited Area for loss of use and enjoyment of their lands since the beginning, and as a result of the atomic tests program

  9. Aspects of environmental monitoring by British Nuclear Fuels plc following the Chernobyl reactor accident

    International Nuclear Information System (INIS)

    The radioactive cloud from the Chernobyl reactor accident arrived in West Cumbria on 2 May 1986. The environmental monitoring facilities of the British Nuclear Fuels plc, Sellafield reprocessing plant were used to monitor radioactivity in air, deposition on grass and on soil and concentrations in milk. The distribution of deposition between sampled grass and soil was affected by heavy rainfall during the passage of the radioactive cloud. Measurements of radioactivity in milk at a lowland farm on the coastal plain resulted in a critical group effective dose of 0.64 mSv up to the end of July, but additional doses are expected to result from the use of silage during the winter. Comparisons are made between these doses from milk consumption and those predicted from the data available shortly after the deposition of the radioactivity on the pasture. (author)

  10. The seismic assessment of British energy nuclear power stations and some pragmatic solutions to seismic modifications

    International Nuclear Information System (INIS)

    British Energy owns and operates 8 Nuclear Power Stations in the United Kingdom. These include seven Advanced Gas-cooled Reactor (AGR) sites and one Pressurised Water Reactor (PWR) site at Sizewell B. As part of the site licence conditions the structures, plant and systems have to be maintained throughout their operational life in such a manner as to maintain their fitness for purpose and to carry out the role allocated to them by the reference safety case. A review, referred to as the Periodic Safety Review of the plant, is carried out every 10 years. The original design intent, changes to codes of practices and the effects of any ageing and/or deterioration are considered and any remedial action necessary is identified. The effects of external hazards are considered as part of that review. Many of the older stations were not designed for, and had never been assessed for the effects of earthquakes. As a consequence, major review work against site-specific seismic hazards has been carried out. In general, the seismic assessment of the plant, systems and structures relies on 'seismic walk-down' techniques, seismic qualification databases, similarity arguments, mathematical models and code of practice comparisons. These techniques are applied to the 'success paths' set out for the two lines of protection required under British Energy 'Nuclear Safety principles'. Where any of the above arguments result in plant modifications, these are implemented on site. The assessment process is described in this paper and some pragmatic solutions to the retrofitting of restraints to, amongst others, electrical cabinets, pipework, masonry walls, and tanks are discussed. Some novel techniques such as the use of structural adhesives are described in detail. (author)

  11. Research by British Nuclear Industry Forum into public support for nuclear power

    International Nuclear Information System (INIS)

    Results of surveys on attitudes to nuclear energy in the United Kingdom are surveyed. When told that nuclear power is used to generate approximately 20% of the country's electricity, 61% of adults agreed that nuclear power was necessary to some extent. The majority of adults (58%) is in favour of nuclear energy making a contribution to a balanced energy policy. There is little unprompted concern about the nuclear industry. The report on the attitudes of experts made the following points: the majority adopt a pragmatic approach; for the pragmatic majority, nuclear has a part to play; the share held by individual fuels at any time is determined by market forces; experts are fairly reassured by the safety record of the nuclear industry; there is concern about waste management, but a view that the problems are under control

  12. Report of the expert committee on the review of data on atmospheric fallout arising from British nuclear tests in Australia

    International Nuclear Information System (INIS)

    The terms of reference of the committee were to review the published scientific literature and other relevant scientific data on the short and long-term effects of fallout arising from British nuclear tests in Australia; to comment on the adequacy of the data available and the collection methodology; to assess the fallout levels arising from each of the tests, the immediate and subsequent hazards from the fallout to the Australian population and individual Australians, including Australian personnel involved and aborigines in South Australia, and the adequacy of the criteria for safe firing of each of the tests. A comparison is made of radiation protection standards adopted during the nuclear test period with current standards. The recommendations include the setting up of a public inquiry to determine how the conduct and consequences of the British nuclear tests affected the health and well-being of Australians

  14. Childhood leukaemia near British nuclear installations: Methodological issues and recent results

    International Nuclear Information System (INIS)

    In 2008, the German Childhood Cancer Registry published the results of the Kinderkrebs in der Umgebung von Kernkraftwerken (KiKK) study of childhood cancer and leukaemia around German nuclear power stations. The positive findings appeared to conflict with the results of a recent British analysis carried out by the Committee on Medical Aspects of Radiation in the Environment (COMARE), published in 2005. The present paper first describes the COMARE study, which was based on data from the National Registry of Children's Tumours (NRCT); in particular, the methodology used in this study is described. Although the results of the COMARE study were negative for childhood leukaemia, this apparent discrepancy could be accounted for by a number of differences in approach, especially those relating to the distances from the power stations and the ages of the children studied. The present study was designed to match the KiKK study as far as possible. The incidence observed (18 cases within 5 km against 14.58 expected, p = 0.21) was not significantly raised. The risk estimate for proximity in the regression fitted was actually negative, though the confidence intervals involved are so wide that the difference from that reported in the KiKK study is only marginally statistically significant (p = 0.063).

  15. Experience with furnace molyware in UO2 sintering plants at British Nuclear Fuels, Springfields

    International Nuclear Information System (INIS)

    British Nuclear Fuels Ltd. produces uranium dioxide pellets for use in advanced gas-cooled reactors (AGR) and pressurised water reactors (PWR) by sintering green pellet compacts at 1750oC in a reducing atmosphere. This work is carried out at the company's Springfields site near Preston in Lancashire. Two routes may be used for pellet production, each of which employs a different type of molyware configuration because of the constraints imposed by furnace design and operation. In the original plant, pellets are sintered on corrugated Mo trays, which are placed in Mo boats. These in turn sit on Mo skids to be pushed through the furnaces. In the second plant, pellets stand upright on flat Mo trays which are stacked on a Mo baseplate to be 'walked' through the furnaces on an incrementing beam. This report will look at modes of failure in both plants, and how changes in the design and/or use of different alloys has been effective in improving the service life of the components. It will be structured such that plants are studied individually, and the changes made noted in chronological order so that the path of the development programme is clear. (author)

    2004-01-01

    @@ Cardiovascular disease takes place in a border-free world. The challenge at the American College of Cardiology (ACC) and anywhere else in the world is to hold patient care above the artificial barriers raised by geopolitical issues. Fundamentally, the goal of ACC members or of any cardiology societies in the world is to provide excellent patient care. Cardiovascular disease is essentially the same throughout the world. Where there are minor variations among individuals, as clinicians we find priceless opportunity to learn. Expanding- rather contracting -our experience base helps us as individuals to realize our best potential as practitioners.

    2010-08-15

    Over the past few years, advances in nuclear medicine aimed at decreasing both the duration and dosimetry of exams, without decreasing image quality. In this setting, Spectrum Dynamics (D-Spect) is a new generation gamma camera dedicated to cardiac scintigraphy. Its technology includes solid-state detectors based on pixelated semiconductors, region-centric (cardiac area) scanning, high-sensitivity collimators and resolution recovery. An additional particularity is the patient position during scanning. Phantom studies showed an improvement of sensitivity compared to conventional cameras, at the price of a loss in geometric resolution, which is compensated by resolution recovery. Semiconductors detectors provide a better energy resolution than conventional detectors suited to double isotope acquisitions, and a high count rate allowing dynamic acquisitions. Only few clinical studies are available so far, they suggest performances similar to that of conventional cameras obtained with acquisitions duration reduced to few minutes. The next step is to establish a trade-off between acquisition duration and dosimetry reduction. (authors)

  18. Nuclear stethoscope and myocard check-like computed method for loading experiments in the State Hospital for Cardiology, Balatonfuered, Hungary

    International Nuclear Information System (INIS)

    The radio-cyclographic technique (RCG) by ECG-triggered coherent averaging has been elaborated firstly for the presentation of cyclical fluctuation of the radioactive indicator in the heart during the equilibrium period, later it was extended to other cardiac products, e.g. mechano-cardiography (M-CG), too. The stroke volume (SV) equivalence of the RCG's amplitude was verified first in Balatonfuered, by dye dilution comparative experiments (corr. coeff. 0.96 in the 40-75 ml/m2 SV-index range). The pressure/volume paralellogram as expression of the momentary cardiac activity has been attempted from the right part of the heart by means of micro-catheterization and RCG, similarly was the RCG-volume and apex-CG 'pressure' loop processed; nowadays the derivation of the left ventricular systolic pressure pattern is attempted on the basis of RCG-volumetry. The ICA-70 multichannel analyser (KFKI) served for the A/D conversion analog curves, directly or from impulse-code modulated magnetic stores, in millisec time resolution. Apart from the averaging, the system can also be used for beat to beat analysis. The other devices are also Hungarian-made: a four-channel radiocirculograph of Videoton, a desk calculator of the EMG type 666/B with 8 K memory, different nuclear instruments of the Gamma Works and a MEDICOR universal ergometer type KE-21. The mathematical operations are: time interval histogram, smoothing of different cyclograms by Fourier processing giving also the accuracy of the fitting by corr. coeff. The program evaluates the time and velocity parameters, like PEP, LVET and their quotient in basal state and during bicycle ergometric load carried out in supine position, under influence of (cardiac) drugs. The program also serves for the volumetric control of the atrial diaanostic pacing and for arrhythmic analysis. RCG-measured SV-monitoring with simultaneous serum myoglobin level determination provides useful prognostic index (by their inverse relations) in the

    2009-09-01

    Full Text Available This article reports upon the emergence of a novel cognitive, computer-based technology which may lead to significantly improved methods of cardiological diagnosis and a rapid and inexpensive method of cardiological screening.The technology ‘Virtual Scanning’ illustrates how, in blood, the reaction of proteins and their reactive substrates releases light; that the colour and intensity of this bioluminescence is unique to each reaction and it’s rate; and that the development of pathologies influence cognition and visual perception. This illustrates that the function of the autonomic nervous system is linked to that of the physiological systems and that the rate of biochemical reactions, and the progression of disease, can be measured by a cognitive test procedure and used as an indication of the disease(s affecting heart function.The article discusses the limitations of the conventional biomarker technique, and the potential value of non-invasive cognitive techniques, such as Virtual Scanning, to the medical practitioner. Finally, it discusses how the ability of Virtual Scanning to diagnose disease from its presymptomatic origins may lead to improved diagnostic accuracy and significantly reduced costs.

  1. ICRP PUBLICATION 120: Radiological Protection in Cardiology

    International Nuclear Information System (INIS)

    Cardiac nuclear medicine, cardiac computed tomography (CT), interventional cardiology procedures, and electrophysiology procedures are increasing in number and account for an important share of patient radiation exposure in medicine. Complex percutaneous coronary interventions and cardiac electrophysiology procedures are associated with high radiation doses. These procedures can result in patient skin doses that are high enough to cause radiation injury and an increased risk of cancer. Treatment of congenital heart disease in children is of particular concern. Additionally, staff in cardiac catheterisation laboratories may receive high doses of radiation if radiological protection tools are not used properly. The Commission provided recommendations for radiological protection during fluoroscopically guided interventions in Publication 85, for radiological protection in CT in Publications 87 and 102, and for training in radiological protection in Publication 113 (ICRP, 2000b,c, 2007a, 2009). This report is focused specifically on cardiology, and brings together information relevant to cardiology from the Commission’s published documents. There is emphasis on those imaging procedures and interventions specific to cardiology. The material and recommendations in the current document have been updated to reflect the most recent recommendations of the Commission. This report provides guidance to assist the cardiologist with justification procedures and optimisation of protection in cardiac CT studies, cardiac nuclear medicine studies, and fluoroscopically guided cardiac interventions. It includes discussions of the biological effects of radiation, principles of radiological protection, protection of staff during fluoroscopically guided interventions, radiological protection training, and establishment of a quality assurance programme for cardiac imaging and intervention. As tissue injury, principally skin injury, is a risk for fluoroscopically guided interventions

    The recent therapeutic advances as the cellular implant as well as those different protocols of image acquisition in the field of the Nuclear Cardiology its have allowed that the patient with severe myocardial damage and without some possibility of revascularization is benefited with these advances. Doubtless the Tl-201 par excellence has an important paper for standardize the more appropriate therapeutic behavior for the heart attack patient; reason by this investigation protocol was developed. The objective of the study was to identify the heart attack regions without viable tissue with SPECT in patient with important myocardial damage without some possibility of traditional revascularization; for the 'Stem cell' cellular implantation therapy. The methodology it was carried out by a study of myocardial perfusion in 10 patients with important myocardial damage previous cellular implants, with PICANUC/ SPECT methodology and using a software (Emory Tool Box) for the image processing validated by the University of Emory Atlanta GA; and using as tracer the Tl - 201 to identify the heart attack regions without presence of viable tissue with an analysis model of 17 segments standardized for the left ventricle; qualifying this way the myocardial perfusion in: 0 (normal), 1 (light), 2 (moderate), 3 (severe), 4 (absent) and x (bad technique). The conclusions were that the SPECT study with PICANUC methodology with Tl-201 is safe and effective for the precise localization for the cellular implantation via direct intra myocardial. (Author)

  3. Occupational dose measurement in interventional cardiology, dosimetry comparison study

    International Nuclear Information System (INIS)

    The number of cardiology interventional procedures has significantly increased recently. This is due to the reliability of the diagnostic equipment to diagnose many heart disease. In the procedures the x-ray used results in increasing radiation doses to the staff. The cardiologists and other staff members in interventional cardiology are usually working close to the area under examination and receive the dose primarily from scattered radiation from the patient. Therefore workers in interventional cardiology are expected to receive high doses. This study overviews the status of occupational exposure at the three cardiology centers at three different hospitals in Khartoum compared with that received by workers at other medical practices (radiotherapy, nuclear medicine and diagnostic radiology) in the Institute of Nuclear and Technology (INMO) at El Gezira. The TLD Harshaw 6600 reader was used in the assessment of effective dose for Hp (10). Two TLDs were used by each worker at the three cardiology centres, one worn under a protective apron and the other worn outside and above the apron as specified by the ICRP. Each worker at the other sections was facilitated with one dosimeter to be worn on the chest. The annual doses received by 14 cardiologists, 13 nurses and 9 technologists at the three cardiology centres were in the range: (0.84-4.77), (0.15-2.08), (0.32-1.10) mSv respectively. In the INMO the annual doses received by 7 doctors, 5 nurses and 14 technologists were in the range: (0.12-0.51), (0.11-0.65), (0.03-1.39) mSv respectively. The results showed that the annual doses received by the workers do not exceed 20 mSv. The study also indicated that doses received by workers in interventional cardiology, in particular the cardiologists are high compared to that received at the other medical sections.(Author)

  4. [Over diagnostic imaging in cardiology].

    Carpeggiani, Clara

    2014-03-01

    Medical imaging is one of the major cause of rising health care costs. Diagnostic imaging has increased more rapidly than any other component of medical care. About 5 billion imaging tests are performed worldwide each year. According to recent estimates, at least one-third of all examinations are partially or totally inappropriate. Two out of 3 imaging tests employ ionizing radiations with radiology or nuclear medicine. The medical use of radiation is the largest man-made source of radiation exposure. Medical X-rays and γ-rays are a proven human carcinogen. The attributable long-term extra-risk of cancer due to diagnostic testing is around 10% in industrialized countries. Cardiologists prescribe and/or directly perform >50% of all imaging examinations, accounting for about two-thirds of the total effective dose given to patients. The dose of common cardiological examinations may be significant: 500 chest X-rays= a stress scintigraphy with sestamibi, 750 chest X-rays= a Multislice Computed Tomography, 1,000 chest X-rays= a coronary angiography and stenting. Unfortunately, few doctors are aware of the level of radiation their patients are exposed to during radiological tests and more intensive use of ionizing testing was not associated with greater awareness. Also as a consequence of unawareness, the rate of inappropriate examinations is unacceptably high in cardiology, even for procedures with high radiation load. Higher exposure doses correspond to higher long-term risks; there are no safe doses, and all doses add up in determining the cumulative risks over a lifetime. Doctors should make every effort so that «each patient should get the right imaging exam, at the right time, with the right radiation dose», as suggested by US Food and Drug Administration in the 2010 initiative to reduce unnecessary radiation exposure from medical imaging. This is best obtained through a systematic implementation of the "3 A's strategy" proposed by the International Atomic Energy

    International Nuclear Information System (INIS)

    In Great Britain, nuclear safety juridic basis is made of two law: HSWA (1974) for hygiene and security in working environment, and NIA (1965) specific to nuclear sites. The HSWA law created an HSC (Hygiene and Security Commission) in charge of workers and public security. HSC executive organ is HSE, whose nuclear office is NSD. Nevertheless, the general philosophy remains the one of HSWA, which results in the liability of operators in nuclear matters, as well as for any other industrial matter. (D.L.). 1 fig., 1 map

  8. The Sandys White Paper of 1957 and the move to the British new look. An analysis of nuclear weapons, conventional forces and strategic planning 1955-57

    International Nuclear Information System (INIS)

    This study seeks to analyse the significance of the 1957 Defence White Paper in the context of British strategic planning during the mid-1950s. Claims that the White Paper represented a culmination of trends already prevalent in British defence planning are assessed while continuities and discontinuities in strategic policies are identified. This is done by highlighting the main features of the document and then tracing their development in the 1955-57 period. A major theme throughout is the relationship between the growing declaratory emphasis on nuclear deterrence and the determination of the shape and size of conventional forces and capabilities. It is contended that the defence decision making process that was in place prior to January 1957 was incapable of generating a British New Look - that is a consistent set of declaratory and action policies which reflected a cutback in conventional forces accompanied by a greater reliance on the threat of nuclear retaliation. Prior to Duncan Sandys becoming Minister of Defence, the inability of that ministry to readily impose itself on the service departments meant that the latter's attachment to preparations for global war and the national service programme could not be overruled. It is also unclear whether during the 1955-56 period the basis for a truly independent deterrent was being established. An analysis of the negotiations surrounding the 1957 White Paper indicates that Sandys was able to overrule traditional service preferences. The result was a policy which rejected the imposition of a conventional strategy on a nuclear one in favour of a British New Look. Consequently, conventional forces were reduced, greater relative importance was placed on the nuclear deterrent, but once more the requirements of a unilateral independent deterrent did not receive priority.

  13. Public health impact of fallout from British nuclear weapons tests in Australia, 1952-1957

    International Nuclear Information System (INIS)

    During the period 1952-1957, Britain conducted 12 full-scale nuclear weapons tests in Australia in five series, viz. Hurricane(1952), Totem(1953), Mosaic(1956), Buffalo(1956) and Antler(1957). Radioactive fallout from the tests reached many parts of Australia. This report reviews the pathways by which the radionuclides in the fallout could have irradiated the population. The methodology is presented for estimating the radiation doses and values are derived from the available data. The possible effect that the radiation exposure had on public health is assessed. Estimation of the radiation doses is approached in two parts: (a) the contributions from the Mosaic, Buffalo and Antler series which were monitored, and (b) the contributions from the Hurricane and Totem series for which there are few fallout data. In part (a), the activities of the radionuclides making up the measured fallout are established by calculation. Standard models are then used to derive the radiation doses for the population centres - from external radiation, from ingestion of radionuclides in food and from inhalation of radionuclides in air. A simple treatment is adopted to estimate radiation doses from drinking contaminated water. For Part (b), the data assembled in (a) provide the basis for developing statistical models for predicting radiation doses from weapon yields and trajectories of the radioactive clouds. The models are then applied to give the radiation doses to population centres following the tests in Hurricane and Totem, using their yields and trajectories. 71 refs., 20 tabs., 8 figs

Different working groups of researches have done efforts to find a new alternative for patients with severe or critical coronary artery disease without possibilities of medical treatment or revascularization procedures. Vascular endothelial growth factor (VEGF) is a hemodimeric glycoprotein of 34-42 kDa with angiogenic activity. pVEGF is a DNA molecule named plasmid that contains the encoded protein of the human VEGF. In recent years, some authors have reported improvement in peripheral vascular disease and coronary artery disease in animal models and in humans treated with different angiogenic factors, mainly VEGF and fibroblastic growth factor. The working group of the Biotechnology and Genetic Engineering Center in Havana has developed a pVEGF with angiogenic activity in vitro provided for this research. Fourteen Yorkshire (25-35 Kg) healthy pigs have been selected for this research. We have performed three studies with 99m Tc Sestamibi Gated SPECT at rest in different moments with the pigs under sedation. First in basal situation. The second one after 21 days of the aneroid constrictor placement in the left coronary tree of the 14 pigs operated by minimum access in order to induce myocardial ischemia, and the third one forty days after intramyocardial minimum access four sites injection of pVEGF(0.5 mg per ml) six animals or saline solution (placebo group) the other six, in a blind randomized fashion. The studies were performed with a DS7 single head gamma camera (SMV, France) coupled to a Power-Vision processor and the Emory-Tool-Box software for cardiac perfusion and function imaging interpretation. Gated SPECT was performed according recommendations and guidelines of the SNM and ASNC.The animals were injected with 25-30 mc of 99m

  16. The mortality and cancer morbidity experience of employees at the Chapelcross plant of British Nuclear Fuels plc, 1955-95

    International Nuclear Information System (INIS)

    The results presented here are from the follow-up of the cohort of workers ever employed at the Chapelcross site of British Nuclear Fuels plc (BNFL) between 1955 and 1995. The study cohort consists of 2628 workers, 2249 of whom were male, who were first employed at the plant before 1 January 1996, and who have 63 967 person-years of follow-up. The mean follow-up period is 24.3 years. The 2209 members of the cohort (84%) classified as radiation workers accumulated 185.1 person-sieverts of external radiation; their median cumulative dose was 39.1 mSv, and 95% of their cumulative doses were less than 339.3 mSv. The Chapelcross workers show the usual 'healthy worker' effect. To the end of 1995, there were 528 deaths among the total cohort (20%), including 449 (20%) amongst the radiation workers. When the dose was unlagged, a statistically significant association was noted between cancer registrations of the buccal cavity and pharynx and dose, based on five cases. When the dose was lagged by 10 years, a statistically significant excess relative risk was noted between all cancer morbidity and dose, 1.80 Sv-1 (0.03 to 4.45), based on 162 cases. This result is driven by the non-significant, but high excess relative risk estimates from the 12 prostatic cancer registrations. A statistically significant association is noted between the eight deaths amongst radiation workers who had prostatic cancer as the underlying cause of mortality and cumulative external radiation dose when the dose was lagged by 0, 2 and 10 years. The association is unlikely to be causal. The finding has little biological plausibility as the strength of the association weakened as the dose lagging increased; it was strongest when the dose was unlagged and disappeared when the dose was lagged by 20 years. None of the workers who was registered for or died from prostatic cancer had ever been monitored for exposure to tritium or to 51Cr, 59Fe, 60Co or 65Zn. There is no evidence to date amongst the

    Background Cardiovascular diseases are the deadliest diseases worldwide, with 17.3 million deaths in 2008 alone. Among them, heart-related deaths are of the utmost relevance; a fact easily proven by the 7.25 million deaths caused by ischemic heart disease alone in that year. The latest advances in smartphones and mHealth have been used in the creation of thousands of medical apps related to cardiology, which can help to reduce these mortality rates. Objective The aim of this paper is to study...

  18. Patient doses in interventional cardiology

    International Nuclear Information System (INIS)

    Cardiovascular diseases are the first cause of death in Spain. The most usual procedures in interventional cardiology are coronariography and PTCA. The first is a diagnostic technique, and the second one is interventional. Our goal has been to study procedures made during the first six months in the Interventional Cardiology Unit of the Juan Ramon Jimenez Hospital (Huelva-Spain), taking into account radiation protection issues. We have studied 178 patients; 145 of them underwent coronariography, and 33 of the patients had PTCA too. Every case was analyzed taking into account technical and dosimetric parameters. We show parameters values gathered: Diagnostic techniques (valvular and non-valvular patients), and interventional techniques (coronariography and PTCA in different or in the same intervention). Higher doses were obtained with valvular patients, although the number of frames was similar. Attending to therapeutic procedures, the highest values were gotten with the 'double' interventions. Interventional procedures exceed in 60% doses gotten in diagnostic studies: this is because of the number of series and number of frames per series. Similar values obtained by other authors have been gotten. (author)

    INTERVENTIONAL: cardiology progress makes each year a greater number of procedures and increasing complexity with a very good success rate. The problem is that this progress brings greater dose of radiation not only for the patient but to occupationally exposed workers as well. Simple methods for reducing or minimizing occupational radiation dose include: minimizing fluoroscopy time and the number of acquired images; using available patient dose reduction technologies; using good imaging-chain geometry; collimating; avoiding high-scatter areas; using protective shielding; using imaging equipment whose performance is controlled through a quality assurance programme; and wearing personal dosimeters so that you know your dose. Effective use of these methods requires both appropriate education and training in radiation protection for all interventional cardiology personnel, and the availability and use of appropriate protective tools and equipment. Regular review and investigation of personnel monitoring results, accompanied as appropriate by changes in how procedures are performed and equipment used, will ensure continual improvement in the practice of radiation protection in the interventional suite.

    Klingler, J W; Andrews, L T; Leighton, R F

    1992-07-01

    A computer-based educational system for the study of cardiovascular imaging is described. This system, based on HyperCard * and a standard Macintosh II, integrates hypertext retrieval, computer graphics, sound, and medical images into a single interactive environment stored on a standard hard disk. This 'hypermedia' approach allows arbitrary complexity coupled with direct, immediate, easy traversal of the images and related text, which provides the opportunity for students to move at their own pace, choose their own direction through the material and repeat as often as desired. Storage on magnetic medium allows for easy updating with new studies and material in order to keep pace with advances in medical imaging technology. The system could be mastered onto CD-ROM for ease of distribution if so desired. The system includes a tutorial on the basics of digital image representation and example studies from cineangiography, nuclear medicine, echocardiography and magnetic resonance imaging of the heart. Quantitative techniques for evaluation of left ventricular function are explained using computer graphics overlays on the original medical images. Color encoded functional images are also included as an aid to visualization of ventricular performance data. The system has proven useful as a primer for digital imaging in cardiology prior to specific case study in a traditional mentor relationship. PMID:1458869

  10. Nuclear cardiologic study of Takotsubo cardiomyopathy

    International Nuclear Information System (INIS)

    Transient left ventricular apical ballooning syndrome, also known as Takotsubo cardiomyopathy (T.T.C.) was described for the first time in Japan in the earliest nineties. It represents 1 to 2 % of acute cardiac events and mimics closely acute myocardial infarction. The aim of this study was to investigate 99 mTc- tetrofosmine or 201Thallium myocardial Single Photon Emission Computed Tomography (SPECT), 123I-meta-iodo-benzyl-guanidine (123I-mibg) myocardial SPECT and myocardial Positron Emission Tomography using 18F-fluorodeoxyglucose (18F-FDG) in patients with T.T.C., assessing respectively left ventricular perfusion, innervation and metabolism. We studied four patients (three females) with T.T.C.. We performed two weeks after acute phase (subacute phase) myocardial perfusion SPECT and 123I-mibg myocardial SPECT for each patient. Two of them underwent myocardial PET with FDG. Then, we assessed left ventricular innervation and metabolism three months (chronic phase I) and more than six months (chronic phase II) after the acute phase. We compared the discrepancies between radionuclides uptake in the left ventricular apical region during a follow-up period of more than six months. In subacute phase, perfusion SPECT was normal for each patient. Conversely, 123I-mibg SPECT and FDG-PET showed concordant apical uptake defect. This perfusion-metabolism pattern called 'inverse flow-metabolism mismatch' is the metabolic state of stunned myocardium. After three months, we found improvement of apical tracer uptake in both FDG-PET and 123I-mibg SPECT. These findings suggest that T.T.C. is characterized by myocardial apical stunning which is related to a disturbance of cardiac sympathetic innervation. 123I-mibg SPECT might be useful to diagnose earlier this pathology and to rule out acute myocardial infarction.

  11. Nuclear cardiology in acute coronary syndromes

    International Nuclear Information System (INIS)

    Acute coronary syndromes are a frequent manifestation of a coronary artery disease, usually being associated with chest pain and presenting as a medical emergency. Since a considerable number of patients with chest pain, however, have a non cardiac etiology of trier pain, properly triaging these patients represents a diagnostic challenge for physicians in the emergency department. As the available diagnostic procedures have limited accuracy, many different diagnostic strategies have been evaluated. Among these, radionuclide myocardial perfusion imaging (MPI) at rest or in combination with stress procedures has been investigated in many trails. MPI has been proven to be useful, especially in a patient population with a low to intermediate probability of an ischemic event. Perfusion scintigraphy has a high sensitivity in the detection of myocardial infarction and reveals an excellent negative predictive value, allowing a safe discharge strategy of patients with a negative scan result. Moreover, it enables risk stratification and provides incremental and independent prognostic information regarding short to long term future cardiac adverse events. Several cost effectiveness studies have shown that perfusion imaging leads to lower overall direct costs, mainly by a reduction of unnecessary hospital admissions and diagnostic angiograms, without worsening of the clinical outcome of these patients. As a possible study endpoint, myocardial perfusion imaging in the acute setting enables the quantification of salvaged myocardium and therefore the evaluation of treatment efficacy. Besides perfusion agents, several infarcts avid radiopharmaceuticals have been developed, which in part show promising results. However, larger randomized trials evaluating these tracers in clinical settings are needed to warrant routine clinical application

  13. Assessing and Reducing Exposures to Cardiology Staff

    International Nuclear Information System (INIS)

    Interventional radiology and interventional cardiology practices represent the highest radiological workload in hospitals and have the potential for high exposures to staff operating near patients. The IAEA has promoted the Information System on Occupational Exposure in Medicine, Industry and Research (ISEMIR) project where the working group on interventional cardiology assessed levels of exposure and methods applied for individual monitoring, and designed an international database of occupational exposures. Worldwide surveys of interventional cardiologists from 32 countries and 81 regulatory bodies from 55 countries provided information on dosimetry practice: only 57% of regulatory bodies define the number and/or position of dosimeters for staff monitoring and less than 40% could provide doses. The survey results proved poor compliance with staff monitoring recommendations in a large fraction of hospitals and the need for staff monitoring harmonization and monitoring technology advancements. Given the new occupational dose limit for the lens of the eye, the existence of high eye doses in interventional cardiology practice and the general lack of knowledge of actual eye doses in interventional cardiology (and other similar interventional practices), ISEMIR recommends improving training in occupational radiation protection and monitoring methods for assessing eye lens doses, and urging hospital management to utilize the international database under development for benchmarking occupational doses in interventional cardiology and, hence, improve optimization of protection.

  14. Safe sedation in modern cardiological practice.

    Furniss, Stephen S; Sneyd, J Robert

    2015-10-01

    Safe sedation is fundamental to many modern cardiological procedures, and following the publication of the report on safe sedation by the Academy of Medical Royal Colleges, this report discusses sedation specifically in cardiological practice. The major areas within cardiology that use sedation are cardioversion, catheter ablation particularly of atrial fibrillation, transoesophageal echocardiography, implantable device (cardiovascular implantable electronic device) procedures and other procedures such as transcatheter aortic valve replacement. There is increasing demand for cardiological sedation but there is wide geographical variation in its use and there are also growing data to support non-anaesthetists giving sedation. The use of benzodiazepines, particularly for short procedures, is common, but even here good record-keeping and audit together with an understanding of the continuum of sedation and having appropriately trained staff and the necessary facilities are vital. Nurse administration of propofol may be appropriate for some procedures in cardiology that require at least moderate sedation. Appropriate training is essential and the use of capnography and target controlled infusion pumps for propofol administration is recommended. PMID:26085525

    Over the last decades, cardiac magnetic resonance(CMR) has transformed from a research tool to a widely used diagnostic method in clinical cardiology. This method can now make useful, unique contributions to the work-up of patients with ischemic and non-ischemic heart disease. Advantages of CMR, compared to other imaging methods, include very high resolution imaging with a spatial resolution up to 0.5 mm × 0.5 mm in plane, a large array of different imaging sequences to provide in vivo tissue characterization, and radiationfree imaging. The present manuscript highlights the relevance of CMR in the current clinical practice and new perspectives in cardiology.

  3. British Energy Operating Experience Programme

    International Nuclear Information System (INIS)

    British Energy is the major nuclear generator in the U.K. It has a market share varying between 22% and 25% of the total U.K. generation. The fleet of power stations operated by British Energy consists of one 1250 MWe Pressurised Water Reactor, six Advanced Gas Cooled reactor sites, each with two reactor units of 660 MWe, and one coal fired site with four units of 500 Mwe. In early 1999 British Energy set a strategic goal, for all its reactor units, to achieve 'World Class Performance through Cost leadership' by the end of year 2004. This would be measured against the applicable Upper Quartile performance indicators of the World Association of Nuclear Operators (WANO). Against this strategic goal six fundamental objectives were identified, one of which was to define, deploy and measure the effectiveness of a world class Operating Experience programme. British Energy has clearly re-defined its Operating Experience programme and, recognised the value of learning from Operating Experience. Commitment to the programme, and communicating the value of an effective OE programme is being clearly demonstrated by all managers throughout the organisation. Making the information easily accessible at the workplace has been achieved via the British Energy intranet, the harder step is to ensure OE is consulted before commencing an assigned task or plant evolution. Early signs of this are encouraging, but a continuous sustained effort will be required for probably the next two years. The full deployment of the OE programme is scheduled to be complete by 2004.

  4. The power of British Energy

    International Nuclear Information System (INIS)

    When the power industry in Britain was privatized, British Energy plc (BE), whose head office is in Edingburgh, Scotland, was founded in July 1996. It is the only power utility in the world exclusively operating nuclear power stations. Operative business has remained the responsibility of the two regional supply companies, Nuclear Electric (NE) and Scottish Nuclear (SN) which, in addition to the modern PWR nuclear generating unit of Sizewell B, have included in the new holding company their advanced gas-cooled and gas-moderated reactor (AGR) units. The older gas-graphite reactor (GGR) plants were combined in the new Magnox Electric plc, Berkeley; at some later date, this company is to be merged with another nuclear power plant operator, British Nuclear Fuels plc (BNFL). Sizewell B, which was commissioned in 1995, is the last nuclear generating unit to be started up in the United Kingdom, for the time being. In times of low raw material prices and the need for a quick return on invested capital, BE is reluctant to run the risk associated with tying up capital for a long time. Instead, the company has backfitted its plants so that the production of electricity from nuclear power in Britain in 1996 of 92,476 GWh was increased by almost 10% over the 1995 level of 84,174 GWh. In addition to modernization and rationalization at home, BE together with Sizewell B vendor Westinghouse is engaged worldwide in the development and commercialization of future advanced reactors. This ensures that the know-how accumulated will be preserved and will be available for new nuclear power plants to be built in Britain in the next century. (orig.)

    "Onco-cardiology" is a term that indicates cardiotoxicity during treatment of malignant diseases. Many studies have demonstrated that chemotherapy agents induce cardiotoxicity in certain ratios. In clinical settings, active malignant diseases or a history thereof are often encountered in patients with cardiovascular disease (CVD); it is not uncommon for a patient to struggle with a prior treatment. We have previously demonstrated a close association between malignant diseases and coronary calcifications in coronary artery disease. The concurrence of arteriosclerotic diseases, including CVD, with malignant diseases should be carefully considered in clinical settings, particularly with regard to scheduled surgical procedures. Moreover, it is essential that all medical professionals associated with cancer care understand these associations. Our advocacy will provide new insight into onco-cardiology. PMID:27107544

    2016-05-01

    Smartphone-based technologies along with broadband connectivity are changing the way modern cardiology is practiced. The ever broadening connectivity and increasing capabilities of smartphone-based technologies can better monitor, diagnose, and prevent cardiovascular diseases. Researchers can leverage the ubiquitous use of smartphone-based technologies and their constant stream of biometric data to establish large community-based clinical research studies. Patient engagement is enhanced with constant and on-demand access to physicians, daily self-monitoring, and expanding social networks. On the other hand, the exponential growth of smartphone-based technologies invariably disrupts the traditional healthcare model and leaves a vacuum in the infrastructure, medico-legal apparatus, and reimbursement systems that need to be addressed. In this review, we present a comprehensive discussion of the various applications utilizing smartphone-based technologies in cardiology. PMID:26686266

    The objective of the study was to compare the frequency of mental disorders in cardiology outpatients to the number of patients with psychological problems identified by cardiologists. In a cardiology outpatient service, 103 consecutive patients were asked to participate in the study. Of these 86...... were included and screened for mental disorder with the Primary Care Evaluation of Mental Disorders (PRIME-MD), Structured Clinical Interview for DSM-IV (SCID) psychosis screening, the Clock Drawing Test, and the WHO-5 Well-being Index. The cardiologists were asked to rate the severity of somatic and...... mental problems in each patient on visual analogue scales (VAS-som and VAS-men). The current treatments, including psychiatric and psychological treatments, were noted, and the survival was followed for 3 years. Of the 86 patients included, 34 (40%) had a diagnosis of mental disorder. Eleven (12.8%) had...

  8. Patient cumulative radiation exposure in interventional cardiology

    International Nuclear Information System (INIS)

    Interventional cardiology procedures can involve potentially high doses of radiation to the patients. Stochastic effects of ionising radiation - radiation-induced cancers in the long term - may occur. We analysed clinical characteristics and dosimetric data in a population of patients undergoing interventional cardiology. In all, 1 591 patients who had undergone coronarography and/or angioplasty in the course of a year at the Saint-Gatien Clinic in Tours (France) were included. Information on patients' individual clinical characteristics and Dose-Area Product values were collected. Organ doses to the lung, oesophagus, bone marrow and breast were mathematically evaluated. The median age of patients was 70 years. Their median cumulative dose-area product value was 48.4 Gy.cm2 for the whole year and the median effective dose was 9.7 mSv. The median organ doses were 41 mGy for the lung, 31 mGy for the oesophagus, 10 mGy for the bone marrow and 4 mGy for the breast. Levels of doses close to the heart appear to be rather high in the case of repeated interventional cardiology procedures. Clinical characteristics should be taken into account when planning epidemiological studies on potential radiation-induced cancers. (authors)

  9. The annal of british RPV steel plates for first nuclear power station in Japan (1). Unforseen accidents araised before nuclear power plant open

    International Nuclear Information System (INIS)

    This article described the author's experiences of reactor vessel steel plates for the first nuclear power station, Tokai-mura reactor. The station is an advanced Calder Hall type. The electrical output is 166 MWe. The reactor vessel was spherical with internal diameter of 189 cm and wall thickness of 83 mm. Material was a fine-grain, aluminum-killed steel. Each part of pressure vessel, bottom cap, belt 1, 2, 3, 4 and top cap, were prefabricated with welding of plates, then lifted into the reactor building and assembled with welding. Steel plates were imported from UK, press formed to spherical segments in Japan and transferred to the site. Ultrasonic testing, magnetic particle testing of groove face (crack detection), sizing of groove and sulfur print tests were performed as an on-site acceptance testing. Inclusions and lamination openings were observed at groove faces due to gas flame cutting. White spot was observed at rupture face of tensile test specimen. At the liquid penetration testing after back gauging of extra seam, a crack-like indication with length of less than 3 mm was observed. Reexamination of groove face by magnetic particles testing showed indications of inclusion cloud or alumina cloud. These would be cracks caused by hydrogen embrittlement. (T. Tanaka)

  10. Acceptance testing and QA in interventional cardiology

    International Nuclear Information System (INIS)

    Interventional radiology has seen rapid growth in the field of cardiology over the past decade. This growth has been facilitated by advances in imaging technology and the development of increasingly sophisticated dedicated radiological equipment. Interventional cardiology (IC) procedures are complex and may involve prolonged irradiations, which may subject patients and operators to higher levels of risk than those, which normally prevail. Currently interventional cardiology contributes over 10% to annual collective dose in the UK in spite of contributing to a total annual frequency of 0.68%. The EU Medical Exposures Directive, 97/43/Euratom, identifies interventional radiology as an area of special concern. Acceptance testing and routine quality assurance (QA) programmes are particularly important in the field of interventional cardiology given the above. The requirements for acceptance testing and QA are underpinned in the EU Medical Exposures Directive and consequent national legislation. A QA survey of 16 interventional cardiology systems in Ireland was carried out by the Department of Medical Physics and Bioengineering, St. James's Hospital, Dublin. This is the continuation of a recently published survey and represents over half of the interventional cardiology systems in Ireland including new technology digital flat panel systems and dedicated mobile equipment in trailors. Acceptance testing and QA protocols were developed and reviewed in accordance with current international and national guidelines, standards and literature. Testing included assessing the performance of the X ray tube and generator, the automatic exposure control (AEC) device in fluoroscopy and digital acquisition modes and a subjective assessment of image quality using the Leeds test objects. Radiation shielding calculations and measurements were performed to determine the structural shielding required by new installations and electrical, mechanical and general radiation safety was also

    Research advancements in cardiology instrumentation and techniques are summarized. Emphasis is placed upon the following techniques: (1) development of electrodes which show good skin compatibility and wearer comfort; (2) contourography - a real time display system for showing the results of EKGs; (3) detection of arteriosclerosis by digital computer processing of X-ray photos; (4) automated, noninvasive systems for blood pressure measurement; (5) ultrasonoscope - a noninvasive device for use in diagnosis of aortic, mitral, and tricuspid valve disease; and (6) rechargable cardiac pacemakers. The formation of a biomedical applications team which is an interdisciplinary team to bridge the gap between the developers and users of technology is described.

  12. Radiological protection in interventional cardiology in Chile

    International Nuclear Information System (INIS)

    In September 2000, an expert mission was assigned to Chile, under the regional project named 'International BBS in Medical Practices Radiation Protection and Quality Assurance In Interventional Radiology' (ARCAL XLIX). The objective of the mission was to evaluate the level of radiation protection (RP) and safety in interventional cardiology ( IC ) installations. A team of local cardiologists, medical physicists and technologists was created for this purpose and during one week, several cardiology laboratories were evaluated and some basic quality controls (QC) were carried out. A basic pilot training course in radiation protection was imparted at the Hospital of the University of Chile in Santiago de Chile and some of the key objectives for a future national quality assurance programme were presented during the national congress of IC. In addition, a national survey on radiation protection aspects was circulated and its results evaluated. These activities enabled the local team to become familiar with the methodology of assessment of the level of protection and the organization of a programme, which was illustrated with the examples of similar European programmes. As result of these actions, several proposals were made to both the local authorities and the IAEA. The most important were: a) to initiate a basic QC programme, b) to organize a training in RP for cardiologists in order to formalize their accreditation, c) to improve personal occupational dosimetry, d) to initiate a programme of patient dosimetry, e) to optimize the technical and clinical protocols, f) to create a national registry of incidents with skin injuries.

    The paper presents the development results of teleconsultative cardiology systems and their application in rehabilitation and sport medicine. The first teleconsultative cardiology (TELECARD) system was developed for outpatient departments in the city of Kaunas, using Internet links. It was based on the CompCardioSignal terminal. One branch of the TELECARD system with a mobile CompCardioSignal terminal was used for functional state evaluation of Lithuanian sportsmen during the 2000 Sydney Olympic Games. The examined results have shown that every sportsman responded differently to acclimatization and the TELECARD system provided support to physicians and coaches for making optimal decisions regarding the sportsmen's adaptation and other situations. The final telemetry system was used for rower monitoring. It was based on the new CompCardioSignal terminal with three EASI ECG leads and synchronously recorded motion signals for evaluation of human reaction to physical load. The developed telemonitoring systems were a useful tool for evaluation of human reaction to physical load in rehabilitation and sports activities. PMID:15718601

  14. The use of MR in cardiological diagnostics

    International Nuclear Information System (INIS)

    Image diagnostics is playing an important role in cardiology, and magnetic resonance tomography (MR) is one of many methods used in examinations of the heart. Based on studies of the literature and his own experience the author surveys the potential of MR in today's and tomorrow's diagnostics of heart diseases. Among the image diagnostic methods MR is the one that can give the most extensive information about the heart's anatomy and function. In a non-invasive way and without the use of ionizing radiation, MR can represent the anatomy in selectable planes, visualize and quantify the heart's pumping function and functioning of the cardiac valves, and give detailed information about the regional contractility, blood flow and viability of myocard. MR is capable of giving important and to some extent unique contributions to heart diseases, both congenital and contracted heart disease. Because of failing availability and competence MR is still little used in cardiological diagnostics, but the method undoubtedly has the potential to play a very important role in the future

  15. Clinical value of thallium 201 in a cardiology service

    International Nuclear Information System (INIS)

    At present the most widely used element in isotopic cardiology is undoubtedly 201Tl. In the few years since its appearance many publication testify to its growing use in the external detection of coronary thrombosis, the discovery of ischemia exertion, the non-traumatic observation of patients after an aortocoronary bridging operation, the diagnosis of coronary deficiency associated with another heart disease (aorta narrowing, mitral prolapsus, obstructive cardiomyopathy) and in combination with two other radioisotopic methods. The present work is intended as a modest contribution, still very recent, to the critical study of this new technique in all its present aspects. Part one presents the various characteristics responsible for the advantages and limits of 201Tl, then describes the techniques and apparatus used. The production, dosimetry, toxicity and biological behaviour of 201Tl are also discussed. A hundred and twenty-five examinations were performed in the Nuclear Medicine Service of the Limoges UHC between May 1977 and October 1978. The results are analysed in part two. This is followed by a discussion which attempts, in the light of our experience, to situate the place occupied by 201Tl in the range of complementary examinations useful in declared or assumed coronary cases. We then propose an examination procedure and precise indications we believe to be justified, accounting for economic problems before considering the future prospects of myocardium scintigraphy

    International Nuclear Information System (INIS)

    This is a study of the British scientific mission to Los Alamos, New Mexico, from 1943 to 1947, and the impact it had on the early history of the atomic age. In the years following the Manhattan Project and the production of the world's first atomic explosion in 1945, the British contribution to the Project was played down or completely ignored leaving the impression that all the atomic scientists had been American. However, the two dozen or so British scientists contributed crucially to the development of the atomic bomb. First, the initial research and reports of British scientists convinced American scientists that an atomic weapons could be constructed before the likely end of hostilities. Secondly their contribution insured the bomb was available in the shortest possible time. Also, because these scientists became involved in post-war politics and in post-war development of nuclear power, they also helped forge the nuclear boundaries of the mid-twentieth century. (UK)

  19. Preliminary reference levels in interventional cardiology

    International Nuclear Information System (INIS)

    This article describes the European DIMOND approach to defining reference levels (RLs) for radiation doses delivered to patients during two types of invasive cardiology procedures, namely coronary angiography (CA) and percutaneous transluminal coronary angioplasty (PTCA). Representative centres of six European countries recorded patients' doses in terms of dose-area product (DAP), fluoroscopy time and number of radiographic exposures, using X-ray equipment that has been subject to constancy testing. In addition, a DAP trigger level for cardiac procedures which should alert the operator to possible skin injury, was set to 300 Gy x cm2. The estimation of maximum skin dose was recommended in the event that a DAP trigger level was likely to be exceeded. The proposed RLs for CA and PTCA were for DAP 45 Gy x cm2 and 75 Gy x cm2, for fluoroscopy time 7.5 min and 17 min and for number of frames 1250 and 1300, respectively. The proposed RLs should be considered as a first approach to help in the optimisation of these procedures. More studies are required to establish certain ''tolerances'' from the proposed levels taking into account the complexity of the procedure and the patient's size. (orig.)

  20. Radiography in cardiology [cardiac disorders, cardiac insufficiency

    International Nuclear Information System (INIS)

    The diagnostic procedure in cardiology nearly always requires an X-ray examination of the thorax. This examination is very informative when it is correctly performed and interpreted. The radiographs need to be read precisely and comprehensively: this includes the evaluation of the silhouette of the heart (size, form and position) as well as the examination of extra-cardiac thoracic structures allowing among other things to search for signs of cardiac insufficiency. The conclusion of the X-ray examination can be drawn after having brought together information concerning the case history, the clinical examination and the study of the radiographs. The radiologist finds himself in one of three situations: (1) the information provided by the X-ray pictures is characteristic of a disease and permits a diagnosis, (2) the X-ray pictures indicate a group of hypotheses; further complementary tests could be useful and (3) the X-ray pictures provide ambiguous even contradictory information; it is necessary to complete the radiological examination by other techniques such as an ultrasonographic study of the heart

    In this paper, we present a new generation of health services that has emerged due to the development of advanced information and communication technology (ICT) solutions, like the Enhanced Personal, Intelligent, and Mobile system for Early Detection and Interpretation of Cardiac Syndromes (EPI-MEDICS). It is a personal self-care system that allows any citizen to self-record high-quality ECGs on demand with a smart portable device, which is endowed with powerful ICT capabilities: self-adaptive embedded intelligence, mobile health record management support on SmartMedia card, embedded Web server, and wireless communication. The EPI-MEDICS solution design also provides ambient, intelligent, and pervasive computing services offering any citizen a ubiquitous, reliable, and efficient management of his/her own cardiac status. A multicentric evaluation performed in Europe with a series of device prototypes and the performance assessment of the original methods of signal synthesis that were designed to guarantee a high interoperability level of the recorded data within the clinical practice, as well as of the decision-support methodologies that were developed for an early detection of life-threatening myocardial ischemia and arrhythmia, at home or anywhere, demonstrate the pertinence of going toward a personal health society in cardiology, which still yields the highest mortality rate in industrialized countries.

  2. Recent advances of MIBG imaging in cardiology

    International Nuclear Information System (INIS)

    The sympathetic nervous system plays an important role in the regulation of cardiovascular function both in healthy subjects and in patients with heart disease. Cardiac neurotransmission imaging allows in vivo noninvasive assessment of presynaptic storage, release and reuptake of neurotransmitters. Iodine-123 labeled metaiodobenzylguanidine (MIBG) is an analogue of the sympatholytic agent guanethidine and behaves in a manner that is similar to norepinephrine, a neurotransmitter of the sympathetic nervous system in the heart. Qualitative and quantitative assessment of MIBG uptake and washout kinetics has evaluated alterations of the cardiac sympathetic function in various heart diseases, such as cardiomyopathies, coronary artery disease, diabetic heart and arrhythmias. As reduced MIBG uptake has been related to the clinical indices of severity and prognosis, it can be used to evaluate the therapeutic effects on the cardiac sympathetic dysfunction. For example, angiotensin converting enzyme inhibitors and β-blockers which have been shown to improve functional capacity and prognosis in patients with heart failure, have been demonstrated to increase MIBG uptake and reduce its washout rate in these patients, indicating favorable effects on the sympathetic nervous system. Thus, MIBG imaging has become a promising noninvasive tool and a widely available modality for the assessment of prognosis and effects of medical therapy in various forms of cardiac pathology. The usefulness and recent advances of MIBG imaging in cardiology will be noted in this article. (author)

    The transition from residency to subspecialty fellowship in a procedurally driven field such as pediatric cardiology is challenging for trainees. We describe and assess the educational value of a pediatric cardiology "boot camp" educational tool designed to help prepare trainees for cardiology fellowship. A two-day intensive training program was provided for pediatric cardiology fellows in July 2015 at a large fellowship training program. Hands-on experiences and simulations were provided in: anatomy, auscultation, echocardiography, catheterization, cardiovascular intensive care (CVICU), electrophysiology (EP), heart failure, and cardiac surgery. Knowledge-based exams as well as surveys were completed by each participant pre-training and post-training. Pre- and post-exam results were compared via paired t tests, and survey results were compared via Wilcoxon rank sum. A total of eight participants were included. After boot camp, there was a significant improvement between pre- and post-exam scores (PRE 54 ± 9 % vs. POST 85 ± 8 %; p ≤ 0.001). On pre-training survey, the most common concerns about starting fellowship included: CVICU emergencies, technical aspects of the catheterization/EP labs, using temporary and permanent pacemakers/implantable cardiac defibrillators (ICDs), and ECG interpretation. Comparing pre- and post-surveys, there was a statistically significant improvement in the participants comfort level in 33 of 36 (92 %) areas of assessment. All participants (8/8, 100 %) strongly agreed that the boot camp was a valuable learning experience and helped to alleviate anxieties about the start of fellowship. A pediatric cardiology boot camp experience at the start of cardiology fellowship can provide a strong foundation and serve as an educational springboard for pediatric cardiology fellows.

    The ICRP has recently recommended reducing the occupational exposure dose limit for the lens of the eye to 20 mSv y(-1), averaged over a period of 5 y, with no year exceeding 50 mSv, instead of the current 150 mSv y(-1). This reduction will have important implications for interventional cardiology and radiology (IC/IR) personnel. In this work, lens dose received by a staff working in IC is studied in order to determine whether eye lens dose monitoring or/and additional radiological protection measures are required. Eye lens dose exposure was monitored in 10 physicians and 6 nurses. The major IC procedures performed were coronary angiography and percutaneous transluminal coronary angioplasty. The personnel were provided with two thermoluminescent dosemeters (TLDs): one calibrated in terms of Hp(3) located close to the left ear of the operator and a whole-body dosemeter calibrated in terms of Hp(10) and Hp(0.07) positioned on the lead apron. The estimated annual eye lens dose for physicians ranged between 8 and 60 mSv, for a workload of 200 procedures y(-1). Lower doses were collected for nurses, with estimated annual Hp(3) between 2 and 4 mSv y(-1). It was observed that for nurses the Hp(0.07) measurement on the lead apron is a good estimate of eye lens dose. This is not the case for physicians, where the influence of both the position and use of protective devices such as the ceiling shield is very important and produces large differences among doses both at the eyes and on the thorax. For physicians, a good correlation between Hp(3) and dose area product is shown. PMID:25809107

    Full Text Available Doron Sudarsky, Eugenia NikolskyCardiology Department, Rambam Health Care Campus and Technion-Israel Institute of Technology, Haifa, IsraelAbstract: Development of contrast-induced nephropathy (CIN, ie, a rise in serum creatinine by either ≥0.5 mg/dL or by ≥25% from baseline within the first 2–3 days after contrast administration, is strongly associated with both increased inhospital and late morbidity and mortality after invasive cardiac procedures. The prevention of CIN is critical if long-term outcomes are to be optimized after percutaneous coronary intervention. The prevalence of CIN in patients receiving contrast varies markedly (from <1% to 50%, depending on the presence of well characterized risk factors, the most important of which are baseline chronic renal insufficiency and diabetes mellitus. Other risk factors include advanced age, anemia, left ventricular dysfunction, dehydration, hypotension, renal transplant, low serum albumin, concomitant use of nephrotoxins, and the volume of contrast agent. The pathophysiology of CIN is likely to be multifactorial, including direct cytotoxicity, apoptosis, disturbances in intrarenal hemodynamics, and immune mechanisms. Few strategies have been shown to be effective to prevent CIN beyond hydration, the goal of which is to establish brisk diuresis prior to contrast administration, and to avoid hypotension. New strategies of controlled hydration and diuresis are promising. Studies are mixed on whether prophylactic oral N-acetylcysteine reduces the incidence of CIN, although its use is generally recommended, given its low cost and favorable side effect profile. Agents which have been shown to be ineffective or harmful, or for which data supporting routine use do not exist, include fenoldopam, theophylline, dopamine, calcium channel blockers, prostaglandin E1, atrial natriuretic peptide, statins, and angiotensin-converting enzyme inhibitors.Keywords: contrast-induced nephropathy, contrast media

  9. British Energy privatisation - 18 months on

    International Nuclear Information System (INIS)

    The TV advertisement which launched the privatisation of British Energy in the summer of 1996 - but just how successful has that privatisation been? And who has benefited - shareholders? The nuclear industry? Our own workforce? Last year, as reported to PIME 97 that the privatisation itself had been successfully completed - following the restructuring of the UK nuclear generation industry, and the creation of British Energy, a new name in the UK - and world energy scene. In simple terms, that privatisation has certainly succeeded - our share price since privatisation has more than doubled, from 2 pounds to well over 4 ponds. Over the last year, it has consistently outperformed the UK electricity sector - particularly over the last winter; it has also out-performed the FR Share Index over the same period, and in December British Energy became one of the UK top 100 listed companies, included in the FTSE 100 having started life at around number 130. This in turn has meant that a number of high quality institutions have taken a second look at British Energy and begun to invest in us as part of a portfolio of FTSE 100 companies. Our success as a private sector company could only be built on the solid foundation of successes as a nuclear utility. Over the five years from 1992 to 1997, our output went up by 64 as Sizewell B came on line and the AGRs achieved their design load factors at last. Safety remains our top priority, and while our profitability increased, so did our safety ratings - accident frequency rates came down by 60%, and collective radiation exposure to our workforce came down 58%. As a result of all this achievement, coupled with reduction in our total workforce, our productivity went up by over 100% - surely proof that nuclear can succeed in a competitive, deregulated electricity market. For future, it has been even more important to sustain that initial success to grow and develop British Energy as a company. The results are there for all to see. In the

  16. Value of nuclear magnetic resonance imaging in cardiology

    International Nuclear Information System (INIS)

    The present study summarizes an experience with Magnetic Resonance Imaging (MRI) in the evaluation of twelve patients with a variety of cardiac abnormalities (myocardial infarction, mural thrombi, obstructive cardiomyopathy, pericarditis). The results are compared with clinical data, with measurements from other techniques such as two-dimensional echocardiography and with the images in normal subjects. An anticipated advantage of MRI is the ability to provide better tissue characterization, than has been attained with other imaging techniques, by relaxation time measurement

    1984-01-01

    This article describes the transformation of the gamma-camera images into digital form. The incidence of a gamma photon on the detector, produces two voltage pulses, which are proportional to the coordinates of the incidence points, and a digital pulse, indicative of the occurrence of the event. The coordinate pulses passes through a analog-digital converter, that is activated by the pulse. The result is the appearance of a digital number at the out-put of the converter, which is proportional to the voltage at its in-put. This number, is stored on the accumulation memory of the system, either on a list mode or on a matrix mode. Static images can be stored on a single matrix. Dynamic data can be stored on a series of matrixes, each representing a different period of acquisition. It is also possible to capture information on a series of matrixes syncronized with the electrocardiogram of the patient. In this instance, each matrix represents a distinct period of the cardiac cycle. Data stored on the memory, can be used to process and display images and quantitative histograms on a video screen. In order to do that, it is necessary to translate the digital data on the memory to voltage levels, and to transform these on light levels on the screen. This, is achieved through a digital analog converter. The reading of the digital memory must be syncronic with the electronic scanning of the video screen. PMID:6466002

  18. Development of radioiodinated fatty acids for applications in nuclear cardiology

    International Nuclear Information System (INIS)

    The use of radioiodinated fatty acids for the evaluation of myocardial perfusion and the assessment of regional fatty acid metabolism in relation to myocardial disease have seen rapid growth in the last few years. In this paper the development and use of these agents are reviewed. In addition to a discussion of the design of structurally modified fatty acids, the development of new radiolabeling methods for preparation of the iodine-123-labeled agents is presented. The development of these new agents is discussed, and their potential use in conjunction with single-photon tomography is an exciting new area. A summary of the clinical studies involving measurement of regional washout rate which have been performed with agents such as 17-([123I]iodo)heptadecanoic acid and 15-(p-[123I]iodo phenyl)pentadecanoic acid is also presented. The combined interest and expertise of chemists and clinicians have worked effectively together to make many recent contributions to this area of radiopharmaceutical development

  1. A critical history of British earthquakes

    Directory of Open Access Journals (Sweden)

    R. M. W. Musson

    2004-06-01

    Full Text Available This paper reviews the history of the study of historical British earthquakes. The publication of compendia of British earthquakes goes back as early as the late 16th Century. A boost to the study of earthquakes in Britain was given in the mid 18th Century as a result of two events occurring in London in 1750 (analogous to the general increase in earthquakes in Europe five years later after the 1755 Lisbon earthquake. The 19th Century saw a number of significant studies, culminating in the work of Davison, whose book-length catalogue was published finally in 1924. After that appears a gap, until interest in the subject was renewed in the mid 1970s. The expansion of the U.K. nuclear programme in the 1980s led to a series of large-scale investigations of historical British earthquakes, all based almost completely on primary historical data and conducted to high standards. The catalogue published by BGS in 1994 is a synthesis of these studies, and presents a parametric catalogue in which historical earthquakes are assessed from intensity data points based on primary source material. Since 1994, revisions to parameters have been minor and new events discovered have been restricted to a few small events.

    The American College of Cardiology Foundation along with key specialty and subspecialty societies, conducted an appropriate use review of common clinical presentations for stable ischemic heart disease (SIHD) to consider use of stress testing and anatomic diagnostic procedures. This document reflects an updating of the prior Appropriate Use Criteria (AUC) published for radionuclide imaging (RNI), stress echocardiography (Echo), calcium scoring, coronary computed tomography angiography (CCTA), stress cardiac magnetic resonance (CMR), and invasive coronary angiography for SIHD. This is in keeping with the commitment to revise and refine the AUC on a frequent basis. A major innovation in this document is the rating of tests side by side for the same indication. The side-by-side rating removes any concerns about differences in indication or interpretation stemming from prior use of separate documents for each test. However, the ratings were explicitly not competitive rankings due to the limited availability of comparative evidence, patient variability, and range of capabilities available in any given local setting. The indications for this review are limited to the detection and risk assessment of SIHD and were drawn from common applications or anticipated uses, as well as from current clinical practice guidelines. Eighty clinical scenarios were developed by a writing committee and scored by a separate rating panel on a scale of 1-9, to designate Appropriate, May Be Appropriate, or Rarely Appropriate use following a modified Delphi process following the recently updated AUC development methodology. The use of some modalities of testing in the initial evaluation of patients with symptoms representing ischemic equivalents, newly diagnosed heart failure, arrhythmias, and syncope was generally found to be Appropriate or May Be Appropriate, except in cases where low pre-test probability or low risk limited the benefit of most testing except exercise electrocardiogram (ECG

  8. QA in interventional cardiology: The lessons learned

    International Nuclear Information System (INIS)

    This presentation describes the methodology, shows the results and analyse the difficulties presented during implementation of the QA programmes in two Interventional Cardiology (IC) Centers of Uruguay in the context of an IAEA coordinated research project that explored the possibility of establishing guidance levels for interventional radiology procedures. First, cardiologists, technicians and nurses received specific information about the QA programme. X ray system tests methodologies were based on the DIMOND European Research Project. Characterizations were performed of the two X ray systems (Picker CV-PRO-1997- and Philips Integris 3000-1995). In clinical conditions (with couch and mattress), for all image intensifier diameters and all fluoroscopy and cine modes, Kerma rate and Kerma per frame (entrance patient dose) were measured with an ionization chamber (10x5-6 E, Radcal) at the entrance of four Plexiglas (PMMA) phantom thicknesses (16, 20, 24 and 28 cm). Simultaneously, spatial resolution and low contrast were evaluated at clinical distance to the monitor by a cardiologist and a physicist, using TOR [18FG] Leeds plate located in the center of the PMMA phantom and in the isocenter of the C-arm. In the same conditions, but for 10, 20 and 30 cm PMMA thicknesses, Kerma rate and Kerma per frame and image quality were studied with NEMA phantom (Standard XR21-2000). Constancy tests were performed with Leeds object test using 4 mm Cu attenuators and Leeds image plate. Kerma rates and Kerma per frame for the same conditions (geometry, cine or fluoroscopy modes, dose modes, image intensifier diameter, FOV and PMMA thickness) were different for each X ray system. As can be seen, values are high in the Philips unit. However, direct (subjective) observation of low and high contrast details of the Leeds test showed similar results. That would require objective evaluation (MTF, noise, contrast and SNR), but they consume more time. Differences in Kerma rate and Kerma per

    Although alpha thalassaemia is rare in north Europeans, it has been identified in British people with no known foreign ancestry. Twelve such patients were studied, of whom eight shared a distinctive molecular defect, which was clearly different from defects seen in subjects of Mediterranean or South East Asian origin. A rare but specific form of alpha thalassaemia is therefore present in the British population. In addition, two patients from families of mixed racial origin were encountered wh...

  12. Scientific evidence and the toxic tort. A socio-legal study of the issues, expert evidence and judgement in Reay and Hope v. British Nuclear Fuels plc

    International Nuclear Information System (INIS)

    Providing a socio-legal analysis of the issues, expert evidence and judgment in Reay and Hope v BNFL plc., the thesis offers an insight into the complexity of the toxic tort. Starting with an overview of the history of Sellafield, the thesis reflects on the scientific and epidemiological concerns surrounding the link between childhood cancer and nuclear installations. Drawing on scientific knowledge and epistemological considerations, the thesis moves on to the difficulties of verifying causation in science and the problems of establishing causation in law. Outlining the role of the expert witness and scientific expert evidence, the thesis proceeds with a case analysis, before broaching the thorny issue of judicial decision making and in particular, the difference between the 'discovery' and 'justification' process. Moving on to the Judgment in Reay and Hope, attention is given to the potential application of probability theory to the judicial decision making process. Lasting just short of one hundred days and including the testimony of numerous scientific experts, Reay and Hope marked new ground in a number of ways; it was the first personal injury claim to test the concept of genetic damage from radiation; the only time that a Queen's Bench Division Judge had been allocated a full-time judicial assistant, and one of the first trials to endorse a satellite video link for examination of international expert witnesses. As far as judicial management is concerned, the case was a forerunner in having Counsels' Opening Statements in writing in advance of the trial, as well as having written daily submissions of key issues from plaintiffs and defendants upon conclusion of oral evidence. The circumstances that led to the trial relate to events in excess of thirty to forty years ago when the fathers of Dorothy Reay and Vivien Hope were employed by the Defendants and their predecessors (the United Kingdom Atomic Energy Authority) as fitters for the Sellafield Plant

  15. Regional futures: British Columbia

    International Nuclear Information System (INIS)

    Two paradigms that are the source of present-day economic development policies are described. The dominant paradigm is the expansionist world view that assumes economic growth is essentially unlimited, subject to certain constraints, and that the best way to monitor the human economy is through money flows. The steady-state or ecological world view assumes there are real constraints on material throughput and growth, and puts a significant emphasis on natural capital as a form of wealth which is distinct from economic or manufactured capital. Over the long term, each generation must receive from the previous generation at least an adequate stock of natural capital assets to ensure long-term sustainability. For every major category of consumption, such as food and energy, an ecological footprint can be assigned which represents the land needed to sustain a given pattern of consumption. For the lower mainland of British Columbia, this footprint would be about 22 times the actual land area; for the Netherlands, it would be about 15 times larger than the country itself. On a global basis, only about 1.7 hectares per capita of ecologically productive land is actually available, showing that Canadian material standards would not be sustainable on a global level. The steady-state approach to economic development would involve a local and regional approach from the bottom up, preferring small-scale labor-intensive enterprise. Trade would be limited to trading in real ecological surpluses, and value-added products would be made locally instead of shipping raw materials for processing elsewhere. 5 figs

    Full Text Available I have before me a copy of a letter dated 12 May, 1814, written by certain Lieutenant-Colonel William Fuller of the King's Dragoon Guards to a British Lord, in which is advised that a commission for His Lordship's son would cost £735. Further on in this article I shall state the prices as they were at the time of the' Crimean War. Only recently did I read a book by a very well-known British author who claims that the British army of the 1850's was small, and that the Crimean War was to prove that it was shockingly organised, but he speaks only well of the navy of that period. I ask that my readers please bear in mind that in earlier days there was no such rank as second-lieutenant nor sub-lieutenant in the British army. The most junior commissioned rank in the infantry was that of ensign. In the cavalry, it was cornet until 1871, when it became sub-lieutenant.

  5. Insurance revolution within British gas

    Energy Technology Data Exchange (ETDEWEB)

    Rooke, R.W.

    1976-07-01

    With the transformation of the British gas industry from a manufacturing to a distribution role, British Gas Corp. questioned the whole function of insurance within the industry and arrived at a new approach of extended self-insurance. The basic questions posed were whether British Gas really needed insurance protection, what size of loss it could absorb within its own financial resources, and what catastrophic losses might occur that should be covered by insurance. In the past, each area board determined its own insurance requirements and obtained the best coverage available for its needs. With the formation of British Gas, however, insurance was investigated on an industry-wide basis by an insurance committee in which each region was represented by its insurance officer. This enabled the industry to negotiate from a position of strength in what would be a bulk purchase and permit the most flexible coverage to be obtained at the most economic cost. The committee proposed a system that made the figure of $3.6 million (pounds 2 million) the main criterion for self-insurance; risks not considered as having a real potential for a loss exceeding this figure would be borne uninsured. Where such potential existed, only amounts above this figure would be insured. The actual program that was eventually adopted cancelled the employer's liability insurance, retained third-party insurance for claims over $3.6 million, retained full-coverage fire insurance, reduced engineering coverage to an inspection service only, retained motor and personal accident insurance for further consideration, and cancelled all other forms of insurance. To implement this program of greater self-insurance, British Gas strengthened the claims-handling expertise within the regions and has incorporated greater risk management techniques to reduce or eliminate risks with loss-making potential.

    Marsden, Alison

    2012-11-01

    Hemodynamics plays an essential role in the progression and treatment of cardiovascular disease. This is particularly true in pediatric cardiology, due to the wide variation in anatomy observed in congenital heart disease patients. While medical imaging provides increasingly detailed anatomical information, clinicians currently have limited knowledge of important fluid mechanical parameters. Treatment decisions are therefore often made using anatomical information alone, despite the known links between fluid mechanics and disease progression. Patient-specific simulations now offer the means to provide this missing information, and, more importantly, to perform in-silico testing of new surgical designs at no risk to the patient. In this talk, we will outline the current state of the art in methods for cardiovascular blood flow simulation and virtual surgery. We will then present new methodology for coupling optimization with simulation and uncertainty quantification to customize treatments for individual patients. Finally, we will present examples in pediatric cardiology that illustrate the potential impact of these tools in the clinical setting.

    Hemodynamics plays an essential role in the progression and treatment of cardiovascular disease. However, while medical imaging provides increasingly detailed anatomical information, clinicians often have limited access to hemodynamic data that may be crucial to patient risk assessment and treatment planning. Computational simulations can now provide detailed hemodynamic data to augment clinical knowledge in both adult and pediatric applications. There is a particular need for simulation tools in pediatric cardiology, due to the wide variation in anatomy and physiology in congenital heart disease patients, necessitating individualized treatment plans. Despite great strides in medical imaging, enabling extraction of flow information from magnetic resonance and ultrasound imaging, simulations offer predictive capabilities that imaging alone cannot provide. Patient specific simulations can be used for in silico testing of new surgical designs, treatment planning, device testing, and patient risk stratification. Furthermore, simulations can be performed at no direct risk to the patient. In this paper, we outline the current state of the art in methods for cardiovascular blood flow simulation and virtual surgery. We then step through pressing challenges in the field, including multiscale modeling, boundary condition selection, optimization, and uncertainty quantification. Finally, we summarize simulation results of two representative examples from pediatric cardiology: single ventricle physiology, and coronary aneurysms caused by Kawasaki disease. These examples illustrate the potential impact of computational modeling tools in the clinical setting.

  11. Investigation of radiation skin dose in interventional cardiology

    International Nuclear Information System (INIS)

    Background - The study investigated the radiation skin doses for interventional patients in cardiology; two procedures which have the highest radiation dose are Radiofrequency Catheter Ablation (RFCA) and Percutaneous Transluminal Coronary Angioplasty (PTCA). Methods and Results - 56 patients were randomly selected and investigated; 23 patients in the RFCA group and 33 in the PTCA group. Skin and effective dose were calculated from Dose Area Product (DAP). Thermoluminescent Dosimetry was the second method of dose measurement used. Patients were followed-up for a three month period to check for possible skin reactions resulting from the radiation dose during the procedure. Radiation skin doses in 14 patients were calculated to be more than 1 Gy, including three patients who received more than 2 Gy, the threshold dose for deterministic effects of radiation. 7 patients (12.5%) reported skin reactions as a result of the radiation received to their backs during the procedure. Mean DAP and estimated effective doses were 105 Gycm2 and 22.5 mSv for RFCA, and 32 Gycm2 and 6.2 mSv for PTCA procedures respectively. Conclusion - Complex procedures in Interventional Cardiology can exceed the threshold level for deterministic effects in the skin. (author)

  13. Heavy water at Trail, British Columbia

    International Nuclear Information System (INIS)

    Today Canada stands on the threshold of a nuclear renaissance, based on the CANDU reactor family, which depends on heavy water as a moderator and for cooling. Canada has a long history with heavy water, with commercial interests beginning in 1934, a mere two years after its discovery. At one time Canada was the world's largest producer of heavy water. The Second World War stimulated interest in this rather rare substance, such that the worlds largest supply (185 kg) ended up in Canada in 1942 to support nuclear research work at the Montreal Laboratories of the National Research Council. A year later commercial production began at Trail, British Columbia, to support work that later became known as the P-9 project, associated with the Manhattan Project. The Trail plant produced heavy water from 1943 until 1956, when it was shut down. During the war years the project was so secret that Lesslie Thomson, Special Liaison Officer reporting on nuclear matters to C.D. Howe, Minister of Munitions and Supply, was discouraged from visiting Trail operations. Thomson never did visit the Trail facility during the war. In 2005 the remaining large, tall concrete exchange tower was demolished at a cost of about $2.4 million, about the same as it cost to construct the facility about 60 years ago. Thus no physical evidence remains of this historic facility and another important artifact from Canada's nuclear history has disappeared forever. It is planned to place a plaque at the site at some point in the future. (author)

    An improved Adaptive Neuro-Fuzzy Inference System (ANFIS) in the field of critical cardiovascular diseases is presented. The system stems from an earlier application based only on a Sugeno-type Fuzzy Expert System (FES) with the addition of an Artificial Neural Network (ANN) computational structure. Thus, inherent characteristics of ANNs, along with the human-like knowledge representation of fuzzy systems are integrated. The ANFIS has been utilized into building five different sub-systems, distinctly covering Coronary Disease, Hypertension, Atrial Fibrillation, Heart Failure, and Diabetes, hence aiding doctors of medicine (MDs), guide trainees, and encourage medical experts in their diagnoses centering a wide range of Cardiology. The Fuzzy Rules have been trimmed down and the ANNs have been optimized in order to focus into each particular disease and produce results ready-to-be applied to real-world patients. PMID:25417018

    2014-09-01

    Full Text Available This article examines the practice of doctors and nurses to invoke the categories of age, sex, class, ethnicity, and/or lifestyle factors when discussing individual patients and patient groups. In what situations are such references explicitly made, and what does this practice accomplish? The material consists of field notes from a cardiology clinic in Sweden, and a theory of descriptive practice guided the analysis. When professionals describe patients, discuss decisions, or explain why a patient is ill, age, sex, class, ethnicity, and/or lifestyle serve as contextualization cues, often including widespread results from epidemiological research about groups of patients at higher or lower risk for cardiac disease. These categories work as shortcut reasoning to nudge interpretations in a certain direction, legitimize decisions, and strengthen arguments. In general, studying the descriptions of patients/clients/students provides an entrance to professional methods of reasoning, including their implicit moral assumptions.

    de Micheli-Serra, Alfredo Alessandro; Izaguirre-Ávila, Raúl

    2014-01-01

    Towards the middle of the XVI century, the empirical physician Martín de la Cruz, in New Spain, compiled a catalogue of the local medicinal herbs and plants, which was translated into Latin by Juan Badiano, professor at the Franciscan college of Tlatelolco. On his side, Dr. Francisco Hernández, the royal physician (protomédico) from 1571 until 1577, performed a systematic study of the flora and fauna in this period. His notes and designs were not published at that time, but two epitomes of Hernández' works appeared, respectively, in 1615 in Mexico and in 1651 in Rome. During the XVIII century, two Spanish scientific expeditions arrived to these lands. They were led, respectively, by the Spanish naturalist Martín Sessé and the Italian seaman, Alessandro Malaspina di Mulazzo, dependent from the Spanish Government. These expeditions collected and carried rich scientific material to Spain. At the end of that century, the Franciscan friar Juan Navarro depicted and described several Mexican medicinal plants in the fifth volume of his botanic work. In the last years of the colonial period, the fundamental works of Humboldt and Bonpland on the geographic distribution of the American plants were published. In the modern age, the first research about the Mexican medicinal botany was performed in the laboratory of the Instituto Médico Nacional [National Medical Institute] under the leadership of Dr. Fernando Altamirano, who started pharmacological studies in this country. Later, trials of cardiovascular pharmacology were performed in the small laboratories of the cardiological unit at the General Hospital of Mexico City, on Dr. Ignacio Chávez' initiative. The Mexican botanical-pharmacological tradition persists alive and vigorous at the Instituto Nacional de Cardiología and other scientific institutions of the country. PMID:24960330

By causing the last decisive step of cerebral, coronary, or peripheral arterial ischemia thrombotic complications of atherosclerotic disease represent a major player in death cause statistics of most western countries. The development of novel therapies against platelet-dependent thrombosis and the concurrent improvement of existing therapeutic strategies thus is a paramount focus of pharmaceutical research. Currently, efficiency, dosing and indications of established antiplatelet substances are being re-evaluated, whilst new, so far unrecognized molecular targets for inhibition of platelet activity come up front. This not only allows for interesting new therapeutical options, but also widens our insight into the role platelets play in atherosclerosis in general. This article summarizes the relevant pathophysiology of platelet activation, presents current concepts in antiplatelet drug therapy, and highlights the role of platelets in vascular diseases apart from atherothrombosis.Keywords: atherothrombosis, antiplatelet drug therapy, pathophysiology, platelet activation

    2014-01-01

    The Mexican cardioangiology started in the nineteen century thanks to first endeavors of surgeons and physicians related to local academies and to School of Medicine, established in 1833 by Dr. Valentin Gómez Farías. Dr. Manuel Carpio, the future first head of department of physiology in this school, translated to Spanish language and published, in 1823, the article On pectoriloquo of the French physician Marat and later performed some experiments on the heart' motion. During the Secont Empire (1864-1867), the physician Samuel von Basch performed studies to define the arterial hypertension, called by him "latent atherosclerosis", i.e. the "essential hypertension". Once he had returned to his country, he invented in 1880, a sphygmomanometer of mercury column, that was the model for the instrument constructed by the Italian physician Scipione Riva-Rocci and presented in 1896. In our time, Dr. Demetrio Sodi Pallares systematized a metabolic therapy called "polarizing therapy", i.e. capable of repolarizing the heart's cells partly depolarized due to hypoxia or direct aggressions. These were the first steps in Mexico on the way to a promising medicine starting and the great adventure of Mexican cardiology. PMID:25260577

  7. Single-photon emission computer tomography (SPECT) and positron emission tomography (PET) imaging in cardiology

    International Nuclear Information System (INIS)

    Nuclear imaging procedures are well-established diagnostic tools in clinical cardiology, providing noninvasive information about myocardial perfusion, cardiac function and metabolism. Scintigraphic parameters provide relevant information that aids in everyday clinical decision making for referring physicians. During the past two decades the clinical role of nuclear medicine procedures in cardiology has evolved significantly. At the beginning, the diagnostic role of nuclear medicine in detecting myocardial ischemia in patients with suspected coronary artery disease has been emphasized and myocardial perfusion imaging with exercise or pharmacological stress testing is a widely accepted technique for the detection and localization of coronary artery disease. The development of Tc-99m labeled perfusion tracers permits combined myocardial perfusion and left ventricular (LV) function studies at a single testing interval. Thus, the potential advantages of simultaneous assessment of myocardial perfusion ad LV function have been recently outlined. Gated imaging of the perfused myocardium is a well-established technique for this purpose, with a single injection of a Tc-99m labeled perfusion tracer. Recent data have demonstrated the impact and clinical role of these studies in the diagnosis of patients with suspected or known coronary artery disease. The addition of functional information to perfusion data has shown to improve the detection of multi-vessel disease. Subsequently, cardiac radionuclide imaging has made significant advances in the determination of prognosis in patients with ischemic heart disease, preoperative risk assessment for patients undergoing non-cardiac surgery and assessment of the efficacy of revascularization in patients undergoing coronary artery bypass surgery or interventional procedures. A key role of myocardial perfusion imaging has been its ability to provide prognostic information in patients after acute myocardial infarction, in patients with

  8. Assessment of patients' skin dose during interventional cardiology procedures

    International Nuclear Information System (INIS)

    During the last 30 years the use of Interventional Cardiology (IC) procedures has increased significantly, mainly due to the benefits and advantages of the method that offers more accurate diagnosis and treatment along with less complications and hospitalization. However, IC procedures are based on the use of x-ray radiation, mostly localized at certain areas of patient's body and for extended periods of time. Consequently, patient may receive high radiation dose and deterministic effects, such as erythema, epilation or even dermal necrosis may be observed. Therefore, the need for reducing radiation dose is highly important. In order to achieve this, good knowledge of the dose levels delivered to the patient during IC procedures is essential since radiation effects are known to increase with dose. It is of great interest to know the point where the maximum skin dose (MSD) is noted since individual sensitivity may vary. MSDs greater than 1 Gy should be recorded. Patient dosimetry during IC procedures is a complex task since these type of procedures depend on various factors, such as complexity and severity of case, different specifications of x-ray equipment and patient's physical characteristics. Moreover, cardiologist's experience plays an important role. For these reasons, Food and Drug Administration (FDA), the International Commission on Radiological Protection (ICRP) as well as the World Health Organization (WHO), have published documents on radiation safety and ways to reduce skin injuries during IC procedures. Various methods have been proposed for measuring MSD such as the use of slow radiotherapy films, thermoluminescent detectors (TLD), scintillation detectors, Dose-Area Product (DAP) meter, as well as a combination of DAP and air kerma. A literature review on MSDs measured during IC procedures showed that doses ranged from 300 to 43000 mGy

  9. Protection Against X-ray Treatment in Intervention Cardiology

    International Nuclear Information System (INIS)

    The aim of this paper is to show basic propositions on protection against ionizing radiation in intervention cardiology. X-ray treatment should also be subjected to all radiological standards and principles of protection against radiation as well as all other radiological examinations. A cardiologist takes over the role of a radiologist after successfully completing additional education. The measures for reducing radiation include professional team, X-ray machines, a diagnostic room and, first of all, a patients body. A long-life diascopy is replaced by aimed photos. Concerning the X-ray machines, filtration, limiting of the bundle of rays and usage of reinforced foils are the important parts. Protection of thyroid gland, eye lenses, ovaries or spermaries and haematic organs must be ensured by safety measures. People who work with x-ray machines must have protective means in working order and personal dosimeters. Protective power of aprons, gloves and glasses must be at least 0.25 mm thick concerning lead. A medical check-up before working with radiation includes a general medical check-up with a working anamnesis and an ophtalmological, gynoecological, dermatological check-up and a psycho test as well as a haematologic analysis, an analysis of chromosome aberration and an urinanalysis. A legal and a physical person who has been appointed to work with the sources of ionizing radiation is obliged to appoint a person responsible for protection against ionizing radiation. The danger which accompanies exposure to radiation cannot be completely eliminated. However, the risk must be limited and reduced by means of administrative, organizational and technological measures. (author)

  10. Radiation dose and image quality for paediatric interventional cardiology

    International Nuclear Information System (INIS)

    Radiation dose and image quality for paediatric protocols in a biplane x-ray system used for interventional cardiology have been evaluated. Entrance surface air kerma (ESAK) and image quality using a test object and polymethyl methacrylate (PMMA) phantoms have been measured for the typical paediatric patient thicknesses (4-20 cm of PMMA). Images from fluoroscopy (low, medium and high) and cine modes have been archived in digital imaging and communications in medicine (DICOM) format. Signal-to-noise ratio (SNR), figure of merit (FOM), contrast (CO), contrast-to-noise ratio (CNR) and high contrast spatial resolution (HCSR) have been computed from the images. Data on dose transferred to the DICOM header have been used to test the values of the dosimetric display at the interventional reference point. ESAK for fluoroscopy modes ranges from 0.15 to 36.60 μGy/frame when moving from 4 to 20 cm PMMA. For cine, these values range from 2.80 to 161.10 μGy/frame. SNR, FOM, CO, CNR and HCSR are improved for high fluoroscopy and cine modes and maintained roughly constant for the different thicknesses. Cumulative dose at the interventional reference point resulted 25-45% higher than the skin dose for the vertical C-arm (depending of the phantom thickness). ESAK and numerical image quality parameters allow the verification of the proper setting of the x-ray system. Knowing the increases in dose per frame when increasing phantom thicknesses together with the image quality parameters will help cardiologists in the good management of patient dose and allow them to select the best imaging acquisition mode during clinical procedures

    OpenAIRE

    Phillips, Alexander

    2013-01-01

    China has undergone massive economic reforms and institutional changes over the last 3 decades. Increasingly liberalized government regulations and the opening up of the Chinese market have attracted British MNCs to enter into this ‘dream market’. This paper seeks to primarily explore the factors that affect the entry mode selection of British MNCs. It will also seek to investigate how the current institutional environment affects entry mode selection. This paper uses a case study method to a...

  20. Dosimetric data and radiation risk analysis for new procedures in interventional cardiology

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate radiation doses to the patients and operators during interventional cardiology procedures, with a particular focus on the transcatheter aortic valve implantation (TAVI). Patient doses for 5549 diagnostic and therapeutic procedures and 76 TAVI were examined, as well as occupational doses to Cardiology Dept. operators. The average patient dose for TAVI was double that of PTCA and six times higher than a simple CA; statistically significant differences were shown in the average patient dose for both trans-femoral and trans-apical access; the measurements show a corresponding increase in the average occupational dose for the cardiologist. Interventional cardiology could increase the collective dose and occupationally exposed worker doses; this increase could be significant if the use of certain procedures is extended to younger people; particular attention in the choice of procedure, optimisation and staff education and organisation is therefore suggested.

  5. Laboratory reconstruction of personal doses in interventional radiology and cardiology

    International Nuclear Information System (INIS)

    People working in interventional cardiology represent one of the most occupationally exposed groups. As recommended by the ICRP, these workers should be equipped with two personal dosemeters, one of them worn on the neck outside the protective collar and the second one on the trunk under the protective apron. It is proved that this double dosimetry method provides more precise estimate of effective dose. In connection with the new lower limit of the eye lens dose, the demands on the eye lens dose estimate increase. The aim of our experiment was to examine the relation between eye lens dose and the quantities Hp(10),Hp(3) or Hp(0.07) measured with conventional personal dosemeters worn on neck and chest. Irradiation conditions imitating the common operation of interventional radiology were created in the laboratory. The patient's body was substituted for a slab PMMA phantom (30 cm x 30 cm x 15 cm). An anthropomorphic Random phantom representing a physician was clothed in a protective apron and a collar, with equivalent of 0.5 mm Pb for both. Three personal multicomponent whole-body thermoluminescent dosemeters (TLD), which allow to measure personal dose equivalents Hp(10),Hp(3) and Hp(0.07), were fixed the Random phantom, one on the collar on the neck and two on the chest over and under the apron. The use of the third dosemeter outside the apron, beyond the recommended double dosimetry, was motivated by the fact that the double dosimetry is not preferred in the Czech Republic yet. Moreover, a special TLD called EYE-D, measuring Hp(3), was employed to determine eye lens dose. It was placed on the Random phantom's temple in the proximity of the eye closer to the radiation source. The utilized PMMA slab phantom was irradiated with X-ray source with the quality RQR5 in four typical irradiation geometries, i.e. radiation beam entered the patient from the front, back, left and right side, which was simulated by the respective arrangement of both the phantoms

  6. Air kerma rates measurement in an interventional cardiology suite

    International Nuclear Information System (INIS)

    In Interventional Cardiology (IC), the assessment of the radiation that the physicians are exposed to is extremely important because the irradiation is not uniform and the received doses are substantially high. During the procedure, the radiation control is complex and there are several reasons for the high exposure levels. It is necessary to perform dosimetric assessments in different parts of the physicians' body and in different specific points of the examination room. By analyzing this information it is possible to determine the probable causes and to provide recommendations, aiming at optimizing the radiological protection. This work had the following objectives: to assess the exposition levels at representative points of critical anatomical regions of the physicians' body who perform IC examinations; to provide means to implement personal monitoring procedures; and to make them aware of the radiation risks. Measurements of air kerma rates were performed in 45 points around the examination table, along the room. Such measurements were made in the conditions frequently used in coronary angiography and coronary angioplasties procedures: adult patient phantom; RAO, LAO and AP incidences; fluoro and digital modes; 13cm and 17cm magnification modes; frequencies of 30f/s (fluoro) and 15 f/s (digital); typical field size used during examinations. Data were obtained at the lenses, chest, hands, gonads and knees levels. For AP incidence, the lowest contributions for scattered radiation and a more homogeneous distribution of radiation were observed. The highest air kerma rates were obtained during digital acquisition mode and for LAO incidence on interventional radiologists, anaesthesists and nurses. The most critical anatomical regions were the knees and gonads. Air kerma rates of about 7,8mGy/h were registered in some places. At physicians' hands position, rates of about 5mGy/h were reached. In several points and levels measured (workload ∼ 6 examinations/day), this

    The Adult Congenital and Pediatric Cardiology (AC/PC) Section was established to develop a clear voice within the American College of Cardiology and address the myriad issues facing the congenital heart disease profession. The Section is governed by the AC/PC Council, which includes pediatric cardiologists, adult congenital cardiologists, a cardiac care associate, and a fellow-in-training member. The Council is responsible for bidirectional communication between the College's Board of Trustees and the AC/PC Section members. Since its founding in 2004, Section objectives have been defined by the College's mission: to advocate for quality cardiovascular care through education, research promotion, and the development and application of standards and guidelines and to influence health care policy. The pillars of the College-advocacy, quality, education, and member engagement-serve as the defining template for the Section's strategy. The Section has developed work groups in advocacy, clinical practice, education and training, quality, and publications. A separate leadership group has been developed for adult congenital heart disease. Work groups are open to all Section members. Recognition of the importance of lifelong care in congenital heart disease led Section leaders to incorporate pediatric cardiology and adult congenital heart disease content into each of the work groups. There are more than 1,200 Section members, with nearly 400 members actively contributing to Section activities. This article outlines Section efforts to date and highlights significant successes to date. PMID:22192673

    Full Text Available In view of recent criticisms concerning vowel symbols in some British English dictionaries (in particular by J. Windsor Lewis in JIPA (Windsor Lewis, 2003, with regard to the Oxford Dictionary of Pronunciation (Upton, 2001, this article extends the discussion on English phonemic transcriptions by including those that typically occur in standard American dictionaries, and by comparing the most common conventions of British and American dictionaries. In addition to symbols for both vowels and consonants, the paper also deals with the different representations of word accentuation and the issue of consistency regarding application of phonemic (systemic, broad, rather than phonetic (allophonic, narrow transcription. The different transcriptions are assessed from the points of view of their departures from the International Phonetic Alphabet, their overlapping with orthographic representation (spelling and their appropriateness in terms of reflecting actual pronunciation in standard British and/or American pronunciation.

  12. Convergence, divergence and realignment in British macroeconomics

    Directory of Open Access Journals (Sweden)

    D. COBHAM

    2013-12-01

    Full Text Available In this paper the author argues that the still frequent and simplistic distinction between Keynesians and monetarists that makes up a large part of the British popular economic debate has become seriously misleading. Changes that have taken place in British macroeconomics since the early 1970s are thus indicated and some of the theoretical and empirical factors responsible for these changes are suggested. The author presents a brief characterisation of British Keynesianism and monetarism as of late 1960s/early 1970s, arguing that there have been important elements of convergence. He proceeds to discuss some of the theoretical developments and some of the experiences of UK macroeconomic policy which have contributed to this convergence. Finally, he considers whether the labels “Keynesian” and “monetarist” continue to be relevant.

    Full Text Available Four overlapping analytical frameworks focusing upon domestic British politics are applied to explain the detailed development of the policy on the euro maintained by the Conservative Government then Party in opposition and the Labour Party opposition and then Government: intra-party politics; inter-party politics; public opinion and the nature of British democracy; and neo-pluralism (competing economic and other interests. This article posits that British government - and in particular Labour Government - reluctance to hold a referendum on euro membership and actively push a pro-euro policy can be best explained in terms of ideologically infused intra- (rather than inter- party politics and the realities of pluralist politics, while explanations rooted in an analysis of public opinion are less helpful.

  17. The establishment of local diagnostic reference levels for paediatric interventional cardiology

    International Nuclear Information System (INIS)

    Background: There is a paucity of information worldwide on radiation exposure in paediatric interventional cardiology. At present Nationally established Diagnostic Reference Levels exist for adult interventional cardiology procedures in the UK but little data is available for paediatrics. In addition, interventional cardiology has been identified as one the highest contributors to medical exposure to ionising radiation and children are more radiosensitive than adults. Objective: This study sought to determine current radiation dose levels in paediatric interventional cardiology (IC) with a view to establishing local diagnostic reference levels (LDRL). Methods: Radiation dose and examination details were recorded for 354 paediatric patients examined by IC in a specialised paediatric centre in Europe. Radiation doses were recorded using a Dose Area Product meter along with examination details. Procedures were categorised as either diagnostic (A) or therapeutic (B). Data was further sub-divided into five age ranges; (1) newborn <1 year (2) 1 <5 years (3) 5 <10 years (4) 10 <15 years (5) 15 years and over. Proposed LDRL were calculated from the mean dose area product readings. Results: The mean patient age was 2.6 years (range 0.0 days–16 years) and weight was 14.9 kg (range 2.4–112 kg). LDRL for the five age groupings were calculated as 190, 421, 582, 1289 and 1776 cGycm² respectively. Conclusion: Local dose reference levels have been proposed for paediatric IC and can be used as a benchmark for other hospitals to compare against their own radiation doses

  18. Paediatric cardiology programs in countries with limited resources: how to bridge the gap.

    Establishing paediatric cardiology service in a country with limited resources like Sudan is a challenging task. A paediatric cardiac team was formed then the services in different disciplines were gradually established. Echocardiography (echo) clinics were founded in tertiary and peripheral hospitals. Cardiac catheterization (cath) was established at the Sudan Heart Centre (SHC) in 2004 and over 400 procedures had been performed including interventional catheterization like pulmonary valve dilatation, patent ductus arteriosus and atrial septal defect device closure. Congenital heart surgery started in 2001, currently 200 cases are done each year including closed procedures as well as open heart procedures for patients weighing more than 8 kg. Cardiology-cardiac surgery as well as adult congenital heart disease meetings were held and contributed positively to the services. The cardiology-cardiac surgery scientific club meeting was founded as a forum for academic discussions. A fellowship program was established in 2004 and included seven candidates trained in paediatric cardiology and intensive care. Two training courses had been established: congenital heart disease echo and paediatric electrocardiogram interpretation. Links with regional and international cardiac centres had important roles in consolidating our program. Significant obstacles face our service due to the small number of trained personnel, high cost of procedures, the lack of regular supplies and lack of cardiac intensive care facilities for young infants. Bridging the huge gap needs extensive official as well as non-governmental efforts, training more staff, supporting families and collaboration with regional and international centres. PMID:23960607

  19. Investigation of the fluoroscopy units used in radiology and cardiology

    International Nuclear Information System (INIS)

    A nationwide survey was launched in 2002 in Switzerland in order to investigate the use of fluoroscopy and to establish national reference levels (RL) for dose intensive procedures particularly in interventional radiology. The two year investigation covered five radiology and nine cardiology departments in public hospitals and private clinics, and focused on twelve types of examinations: six diagnostic and six interventional. The performance of the fluoroscopy units used in these healthcare centres (image quality and dose) was assessed extensively. This characterization was useful since, unlike the American RAD-IR study where the fluoroscopy units where similar (Siemens, with Cu filtration), a large variability in the brands and the technical specifications of the fluoroscopy units used in the participating centres are registered in our case. The units are often programmed according to the anatomical region under investigation. Knowledge of the parameters used for the various categories of examinations is crucial for analysis of the results of the survey. First, the DAP meters of the fluoroscopy units were checked using an external reference DAP meter put on top of the measuring device of the fluoroscopy unit. The units were then characterized in terms of the image quality and the patient dose associated to the various modes used. Assessment of the image quality consisted of establishing the spatial resolution limit at the middle of a Leeds TOR(CDR) Test Object. The dose measurements were performed using an 11 cm3 ionization chamber connected to a Radcal 3036 dosemeter and a 20 cm thick PMMA phantom. The characteristics of the fluoroscopy units (dose rate, dose per frame, image quality index and spatial resolution) were established for three imaging modes (radiography, fluoroscopy and cine), various diameters (or magnifications) of the image intensifier and various imaging frequencies and for six categories of examinations: 1) barium based examinations, 2) bile

  20. Ambient Noise Tomography of the British Isles

    2009-12-01

    In recent years, surface wave tomography using empirical Green’s functions computed via the ambient noise interferometry method has become an established approach to lithospheric imaging problems. To date, ambient noise tomography has been successfully applied to seismometer arrays in the United States, Australia, Iceland, China, South Africa, Europe and the Tibetan Plateau. The basis of the ambient seismic interferometry method is that, by cross-correlating noise data between two seismic stations and stacking over a long enough time period, one can approximate the Green’s Function that would have been recorded at one of the stations if the other had actually been a source. Consequently, one of the main advantages of ambient noise interferometry is that traditional seismic sources such as earthquakes or ballistics are not required; therefore it is ideal for application to seismically quiescent areas such as the British Isles. The British Isles are an archipelago located adjacent to the Eurasian continental shelf in a typically intra-plate setting, formed by a complex amalgamation of several terranes. These range from Laurentian north of the Highland Boundary fault to Avalonian south of the Iapetus Suture and evidence of the regions turbulent geological past can be inferred from its lithospheric structure. Previous studies of the structure of the British Isles considered relatively few seismic stations and/or were limited to using offshore shots, quarry blasts or teleseismic earthquakes as seismic energy sources. We have applied the ambient noise tomography method to noise data recorded on approximately 100 broadband and short period seismometers, including many new stations, in the British Isles and mainland Europe. This dense coverage of the British Isles allows us to image the crust and upper mantle velocity structure with a horizontal resolution in the region of 100km across the North Sea and 30km in the mainland United Kingdom. Here we present the first

  5. The nuclear power decisions

    International Nuclear Information System (INIS)

    Nuclear power has now become highly controversial and there is violent disagreement about how far this technology can and should contribute to the Western energy economy. More so than any other energy resource, nuclear power has the capacity to provide much of our energy needs but the risk is now seen to be very large indeed. This book discusses the major British decisions in the civil nuclear field, and the way they were made, between 1953 and 1978. That is, it spans the period between the decision to construct Calder Hall - claimed as the world's first nuclear power station - and the Windscale Inquiry - claimed as the world's most thorough study of a nuclear project. For the period up to 1974 this involves a study of the internal processes of British central government - what the author terms 'private' politics to distinguish them from the very 'public' or open politics which have characterised the period since 1974. The private issues include the technical selection of nuclear reactors, the economic arguments about nuclear power and the political clashes between institutions and individuals. The public issues concern nuclear safety and the environment and the rights and opportunities for individuals and groups to protest about nuclear development. The book demonstrates that British civil nuclear power decision making has had many shortcomings and concludes that it was hampered by outdated political and administrative attitudes and machinery and that some of the central issues in the nuclear debate were misunderstood by the decision makers themselves.

  14. British Columbia Utilities Commission 2000 annual report

    International Nuclear Information System (INIS)

    The main responsibility of the British Columbia Utilities Commission is to regulate the energy utilities under its jurisdiction to ensure that energy rates are fair and that utility operators in the province provide safe, adequate and secure service to their customers. The Commission also approves the construction of new facilities planned by utilities. In addition, it participates in the review of utility and energy projects under the Environmental Assessment Act. This report notes that the most significant development in 2000 was the sharp increase in the continental market price for natural gas, and in the winter spot price spikes in the west from southern British Columbia to California. As a result, the Commission had to approve large rate increases for BC gas customers. These high prices had a marked impact on cost of living and operating costs. In British Columbia, electricity rates are based on the cost of generation, transmission and distribution. Electricity rates have been, and will continue to be frozen for B.C. Hydro customers until October 2001. The Commission has instituted transmission access principles and tariffs for B.C. Hydro and West Kootenay Power to make it possible for these utilities to participate in regional electricity markets. The report also noted that the movement toward increased competition and deregulation of electricity markets in British Columbia has lost momentum, given the experiences in California and Alberta. tabs., figs

    Full Text Available Abstract Context There is considerable concern about the spread of HIV disease among Aboriginal peoples in British Columbia. Objective To estimate the number of Aboriginal British Columbians infected with HIV. Design and setting A population-based analysis of Aboriginal men and women in British Columbia, Canada from 1980 to 2001. Participants Epidemic curves were fit for gay and bisexual men, injection drug users, men and women aged 15 to 49 years and persons over 50 years of age. Main outcome measures HIV prevalence for the total Aboriginal population was modeled using the UNAIDS/WHO Estimation and Projection Package (EPP. Monte Carlo simulation was used to estimate potential number infected for select transmission group in 2001. Results A total of 170,025 Aboriginals resided in British Columbia in 2001, of whom 69% were 15 years and older. Of these 1,691 (range 1,479 – 1,955 men and women aged 15 years and over were living with HIV with overall prevalence ranging from 1.26% to 1.66%. The majority of the persons infected were men. Injection drug users (range 1,202 – 1,744 and gay and bisexual men (range 145, 232 contributed the greatest number of infections. Few persons infected were from low risk populations. Conclusion More than 1 in every 100 Aboriginals aged 15 years and over was living with HIV in 2001. Culturally appropriate approaches are needed to tailor effective HIV interventions to this community.

    In the period since 2001, cinema has witnessed what David Butler refers to as a ‘golden age’ of fantasy film production. The majority of fantasy films released during this time have originated from British literature, and have to some extent been produced and located within Britain, showcasing a wealth of national characters, acting talent, and landscapes on screen. Yet, despite vital revisionist work conducted on British horror, science fiction and melodrama, there remains a hesitancy to emb...

  1. The Information System on Occupational Exposure in Medicine, Industry and Research (ISEMIR): Interventional Cardiology

    International Nuclear Information System (INIS)

    In the last three decades, the use of image guided interventional procedures in cardiology has increased significantly, bringing great benefit to millions of patients around the world. As technology improves, the medical capabilities of these procedures continue to expand, adding further to the armamentarium for diagnosis and treatment of patients with cardiac problems. All of these procedures require health professionals (including interventional cardiologists, electrophysiologists, nurses and medical radiation technologists) to be present in the room and alongside the patient when radiation is being used, which may result in occupational exposure. While it has been long known that there is significant potential for health professionals in attendance during interventional cardiology to receive non-trivial occupational exposures, reported details have been typically limited to a few specific interventional cardiology facilities and situations. A more global perspective has been lacking, as is the availability of a systematic means for improving occupational radiation protection in interventional cardiology facilities throughout the world. In 2006, the IAEA published the Fundamental Safety Principles (IAEA Safety Standards Series No. SF-1), which sets out the fundamental safety objective and principles of protection and safety. In 2011, the IAEA published Radiation Protection and Safety of Sources: International Basic Safety Standards (IAEA Safety Standards Series No. GSR Part 3 (Interim Edition)), which sets out the requirements for meeting the fundamental safety objective and applying the principles specified in the Fundamental Safety Principles. The establishment of safety requirements and provision of guidance on occupational radiation protection is a major component of the support for radiation protection and safety provided by the IAEA to Member States. This publication was developed under the IAEA's statutory responsibility to facilitate worldwide application

  2. Creating a website that will really work for your organisation: The British Energy experience

    International Nuclear Information System (INIS)

    Full text: There is no doubt that the Internet is going to be the communications power tool of the future. Judging by the number of top line companies who have quality websites and the number of website addresses that appear in press and television advertisements, few organisations who mean business can afford to ignore this exciting, fast moving medium. The Internet - millions of computers which can 'talk to each other' via telephone lines - has been described as revolutionary in communication terms as the wheel was to transport. As we enter a new millennium, the Internet is becoming more than just a huge information resource, it is increasingly being developed to carry out business transactions - already we can shop for groceries, find a mortgage and send bouquets on line. British Energy's award-winning website was launched in the European Parliament in April, just two months after a London-based design company had accepted a tight audience-led specification that included clarity of design, promotion of the British Energy brand and, most importantly, ease of navigation. British Energy had identified its key objectives. Number one was the promotion of British Energy the brand in relation to its better-known subsidiary companies, Nuclear Electric and Scottish Nuclear. As the Internet is a truly global medium, accessible 24-hours a day, it was recognised that it could be particularly important in reaching potential partners and customers. British Energy certainly made clear its global aspirations from the outset and therefore it was important that visitors to the site understood what the company was and from whence it came. The audience-led strategy is delivering quality information to the people British Energy are most keen to communicate with. The sharetracking feature, news desk and narrated video tour of Sizewell B, the Pressurised Water Reactor, are amongst the most popular aspects. In December, British Energy won the 'Best Annual Report' on the Internet award

  5. Energy white paper 2007: the British strategy to take up the energy challenge

    International Nuclear Information System (INIS)

    Following the energy policy review published in 2006 by the Department for Trade and Industry (DTI), the Energy White Paper 2007, published on May 23, 2007, gathers all measures preconized in this domain. This document recalls, first, the objectives and priorities of the British government at the international, national, regional and local scales, as already clearly explained in previous DTI publications. This white book announces also some new measures and the launching of new public hearings about other measures in view. All in all, 18 hearings are announced which deal with various topics, from the new nuclear power plants to the reform of renewables obligations, the organization of big energy projects or the dismantling of offshore energy facilities. This document recalls the objective of the government and describes the British international policy in the domain of energy. It presents the measures for the fight against climatic change (energy conservation, development of clean energies, decentralized energy production), for warranting the security of supplies (diversification of offer, improvement of networks, planning of energy projects) and, in particular, the proposals of the government concerning the transportation sector and the fight against energy paucity. It stresses also on the importance of R and D and on the British authority in energy technologies. Finally, it gathers the reactions of the most representative actors of the British energy sector.

  6. The nuclear power in the UK electricity market: from a limited future to eternal life and back again?

    Energy Technology Data Exchange (ETDEWEB)

    Thomas, S.

    2002-07-01

    In 1990, the privatisation of the British electricity supply industry revealed how uneconomic Britain's nuclear power plants were. The nuclear sector was withdrawn from privatisation and it seemed likely that by 2000, most of Britain's nuclear power plants would be closed. However, operating costs were dramatically reduced and in 1996, most of the nuclear plants were privatised in British Energy. Nuclear output made an important contribution to the reduction of greenhouse gas emissions and the future looked secure for the existing plants. However, the early success of British Energy was based on an inflated wholesale electricity price and by 2000, British Energy was struggling to cover its costs. The British government is now conducting a review of energy policy. The economic case for new nuclear power plants is poor but the need to meet greenhouse gas emission targets and the influence British Energy and BNFL may ensure the long-term future of the existing plants.

  7. Inspection of cardiology departments in Norway: are they making it great in radiation protection?

    International Nuclear Information System (INIS)

    Staff involved in interventional cardiology receive the highest occupational doses in Norway, and skin burns of patients have been reported. To identify the level of radiation protection (RP) for patients and staff, and compliance with the RP regulation, the Norwegian Radiation Protection Authority carried out inspections. The inspections were conducted (2013-14) as quality system reviews, based on document reviews, interviews, on-site inspections and observations of interventional procedures. The inspections revealed that most of the hospitals had non-compliancies according to the RP regulation. Most deviations were associated with education in RP and follow-up of patients who had received high radiation doses. Lack of systematic optimisation of procedures and estimation of eye lens doses to evaluate the risk for cataracts were also common. Inspections turned out to increase the awareness of RP in cardiology and are identified as an effective tool for improving RP. (authors)

    This study aimed at comparing neuropsychological test scores in 83 cardiologists and nurses (exposed group, EG) working in the cardiac catheterization laboratory, and 83 control participants (non exposed group, nEG), to explore possible cognitive impairments. The neuropsychological assessment was carried out by means of a battery called "Esame Neuropsicologico Breve." EG participants showed significantly lower scores on the delayed recall, visual short-term memory, and semantic lexical access ability than the nEG ones. No dose response could be detected. EG participants showed lower memory and verbal fluency performances, as compared with nEG. These reduced skills suggest alterations of some left hemisphere structures that are more exposed to IR in interventional cardiology staff. On the basis of these findings, therefore, head protection would be a mandatory good practice to reduce effects of head exposure to ionizing radiation among invasive cardiology personnel (and among other exposed professionals).

    The National Academy of Medicine was founded 141 years ago during the French intervention. Under the sponsorship of this brand-new medical association, Mexican cardioangiology took its first steps in the medical and surgical field as well. After the falling of the second empire, the medical and surgical advances of this discipline continued. The corresponding publications appeared in different volumes of the "Gaceta Médica de México"; at present journal of the Academy still published in our time. These steps permitted the development of the true cardiologic speciality during 40s of the twentieth century, due to the vision of Professor Ignacio Chávez, father of Mexican cardiology. Some examples of application are the epistemologic criteria in cardiologycal domains such as the conception of Riva-Rocci's sphygmomanometer in Italy in the nineteenth century and the so-called cardiac metabolic therapy in Mexico of our time, are included.

    2011-03-01

    Within the Information System on Occupational Exposure in Medicine, Industry and Research (ISEMIR), a new International Atomic Energy Agency initiative, a Working Group on interventional cardiology, aims to assess staff radiation protection (RP) levels and to propose an international database of occupational exposures. A survey of regulatory bodies (RBs) has provided information at the country level on RP practice in interventional cardiology (IC). Concerning requirements for wearing personal dosemeters, only 57 % of the RB specifies the number and position of dosemeters for staff monitoring. Less than 40 % of the RBs could provide occupational doses. Reported annual median effective dose values (often <0.5 mSv) were lower than expected considering validated data from facility-specific studies, indicating that compliance with continuous individual monitoring is often not achieved in IC. A true assessment of annual personnel doses in IC will never be realised unless a knowledge of monitoring compliance is incorporated into the analysis. PMID:21051431

    Full Text Available OBJECTIVES: Cardiology referral is common for patients admitted for non-cardiac diseases. Recommendations from cardiologists may involve complex and aggressive treatments that could be ignored or denied by other physicians. The purpose of this study was to compare the outcomes of patients who were given recommendations during cardiology referrals and to examine the clinical outcomes of patients who did not follow the recommendations. METHODS: We enrolled 589 consecutive patients who received in-hospital cardiology consultations. Data on recommendations, implementation of suggestions and outcomes were collected. RESULTS: Regarding adherence of the referring service to the recommendations, 77% of patients were classified in the adherence group and 23% were classified in the non-adherence group. Membership in the non-adherence group (p<0.001; odds ratio: 10.25; 95% CI: 4.45-23.62 and advanced age (p = 0.017; OR: 1.04; 95% CI: 1.01-1.07 were associated with unfavorable outcomes. Multivariate analysis identified four independent predictors of adherence to recommendations: follow-up notes in the medical chart (p<0.001; OR: 2.43; 95% CI: 1.48-4.01; verbal reinforcement (p = 0.001; OR: 1.86; 95% CI: 1.23-2.81; a small number of recommendation (p = 0.001; OR: 0.87; 95% CI: 0.80-0.94; and a younger patient age (p = 0.002; OR: 0.98; 95% CI: 0.96-0.99. CONCLUSIONS: Poor adherence to cardiology referral recommendations was associated with unfavorable clinical outcomes. Follow-up notes in the medical chart, verbal reinforcement, a limited number of recommendations and a patient age were associated with greater adherence to recommendations.

    Full Text Available Abstract Miniaturization has evolved in the creation of a pocket-size imaging device which can be utilized as an ultrasound stethoscope. This study assessed the additional diagnostic power of pocket size device by both experts operators and trainees in comparison with physical examination and its appropriateness of use in comparison with standard echo machine in a non-cardiologic population. Three hundred four consecutive non cardiologic outpatients underwent a sequential assessment including physical examination, pocket size imaging device and standard Doppler-echo exam. Pocket size device was used by both expert operators and trainees (who received specific training before the beginning of the study. All the operators were requested to give only visual, qualitative insights on specific issues. All standard Doppler-echo exams were performed by expert operators. One hundred two pocket size device exams were performed by experts and two hundred two by trainees. The time duration of the pocket size device exam was 304 ± 117 sec. Diagnosis of cardiac abnormalities was made in 38.2% of cases by physical examination and in 69.7% of cases by physical examination + pocket size device (additional diagnostic power = 31.5%, p In conclusion, pocket size device showed a relevant additional diagnostic value in comparison with physical examination. Sensitivity and specificity were good in experts and suboptimal in trainees. Specificity was particularly influenced by the level of experience. Training programs are needed for pocket size device users.

  3. Assessment and Utility of Frailty Measures in Critical Illness, Cardiology, and Cardiac Surgery.

    Science.gov (United States)

    Rajabali, Naheed; Rolfson, Darryl; Bagshaw, Sean M

    2016-09-01

    Frailty is a clearly emerging theme in acute care medicine, with obvious prognostic and health resource implications. "Frailty" is a term used to describe a multidimensional syndrome of loss of homeostatic reserves that gives rise to a vulnerability to adverse outcomes after relatively minor stressor events. This is conceptually simple, yet there has been little consensus on the operational definition. The gold standard method to diagnose frailty remains a comprehensive geriatric assessment; however, a variety of validated physical performance measures, judgement-based tools, and multidimensional scales are being applied in critical care, cardiology, and cardiac surgery settings, including open cardiac surgery and transcatheter aortic value replacement. Frailty is common among patients admitted to the intensive care unit and correlates with an increased risk for adverse events, increased resource use, and less favourable patient-centred outcomes. Analogous findings have been described across selected acute cardiology and cardiac surgical settings, in particular those that commonly intersect with critical care services. The optimal methods for screening and diagnosing frailty across these settings remains an active area of investigation. Routine assessment for frailty conceivably has numerous purported benefits for patients, families, health care providers, and health administrators through better informed decision-making regarding treatments or goals of care, prognosis for survival, expectations for recovery, risk of complications, and expected resource use. In this review, we discuss the measurement of frailty and its utility in patients with critical illness and in cardiology and cardiac surgery settings. PMID:27476983

In doing so, we obtained evidence that 13 species of Tuber occur in the province, including six introduced and seven native species, two of which are putative undescribed species. Of the native species, the Tuber anniae species complex is widely distributed in the province while Tuber beyerlei appears to be much more restricted in distribution. Four of the introduced species have commercial value (Tuber melanosporum, Tuber aestivum, Tuber brumale, and Tuber borchii) as do two of the native species (Tuber gibbosum and Tuber oregonense). Focused sampling on likely tree hosts, both hardwood and Pinaceae species, as well as in currently unexplored parts of the province seems likely to expand our knowledge of the diversity and distribution of Tuber species in British Columbia.

    The paper is a brief outline of the first stage of a comparative research project in the role and adequacy of care credits in the British and German pension systems. The provision of care credits has been an essential part of pension reforms around Europe, which significantly changes the prospects of carers to accumulate adequate pension contributions through their life course. But although the policy significance of care credits is due to rise in line with an increasing demand...

  7. Population Ecology of Caribou in British Columbia

    The abundance and geographic range of woodland caribou (Rangifer tarandus caribou) decreased in many areas of British Columbia during the 1900's. Recent studies have found that predation during the summer is the major cause of mortality and current population declines. Increased moose {Alecs alces) populations may be related to past and current caribou declines by sustaining greater numbers of wolves (Canis lupus). Mortality rates were greater in areas where caribou calved in forested habitat...

  8. Nostalgia versus Feminism in British Costume Drama

    This essay examines the phenomenon of (mainly British) costume drama during the last twenty-five years and the theoretical debate surrounding the socalled 'heritage' film. Critics of the 1980s and 1990s saw in the heritage film an attempt to exploit the nostalgic and conservative appeal of the historical costume drama in order to support the Thatcherite political project of redefining and reorientating national identity. Yet the costume drama, with its independently-minded heroines and its sh...

    Import protection is frequently advocated as a means of preserving jobs and avoiding labour adjustment costs. Defining adjustment costs in terms of output forgone during the process of adjustment and ignoring any general equilibrium repercussions, we estimate that quantitative restrictions on British footwear imports during 1979 protected about 1,000 jobs and avoided once-and-for-all adjustment costs of only around 1 million pounds sterling. The result is based on new data which reveal high r...

  13. Electricity trade: Generating benefits for British Columbians

    International Nuclear Information System (INIS)

    Electricity has been traded in British Columbia since the turn of the century. In 1988, the provincial government established the British Columbia Power Exchange Corporation (Powerex) to conduct electricity trade activities in order to make the most efficient use of the electrial system and generate benefits for British Columbians. The trade is made possible by an interconnected system linking producers and consumers in western Canada and the USA. Provincial participants in the trade include British Columbia Hydro, independent power producers, and cogenerators. Benefits of the electricity trade include generation of revenue from sale of surplus power, being able to buy electricity when the mainly hydroelectric provincial system is in a drought condition or when major shutdowns occur, and enabling postponement of development of new power projects. Powerex conducts its trade under provincial and federal permits and licenses. Different types of trade contracts are negotiated depending on the amount and availability of electricity and the kind of trade being conducted. Exchanges and coordination agreements allow transfer and return between utilities with no net export occurring, allowing balancing of loads between different reigons. Surplus electricity is bought or sold on a short- or long-term basis and on firm or non-firm terms. Electricity exports are not subsidized and are only allowed if the electricity is surplus to provincial needs and can be sold at a profit. A new provincial policy allows private industry to export long-term firm electricity; this involves construction of new private-sector generating facilities solely for the purpose of export. 1 fig

  17. The British Model in Britain: Failing slowly

    International Nuclear Information System (INIS)

    In 1990, Britain reorganised its electricity industry to run on competitive lines. The British reforms are widely regarded as successful and the model used provides the basis for reforms of electricity industries worldwide. The main reason for this perception of success is major reductions in the real price of electricity with no reduction in service quality. This paper examines whether the reputation of the British reforms is justified. It concludes that the reputation is not justified and that serious fundamental problems are beginning to emerge. The central question is: have the British reforms resulted in the creation of efficient wholesale and retail markets? On this criterion, the reforms have failed. The wholesale market is dominated by obscure long-term contracts, privileged access to the market and self-dealing within integrated generator/retailers, leaving the spot markets with minimal liquidity and unreliable prices. The failure to develop an efficient wholesale market places the onus on consumers to impose competitive forces on electricity companies by switching regularly. Small consumers will not do this and they are paying too much for their power. For the future, there is a serious risk that the electricity industry will become a weakly regulated oligopoly with a veneer of competition. (author)

  20. British Columbia natural gas: Core market policy

    International Nuclear Information System (INIS)

    The core market for natural gas in British Columbia is defined as all natural gas consumers in the residential, institutional, commercial, and industrial sectors not currently purchasing natural gas directly and not exempted from the core market by the British Columbia Utilities Commission (BCUC). The intent of the definition is to include all customers who must be protected by contracts which ensure long-term security of supply and stable prices. Core market customers are excluded from direct natural gas purchase and will be served by distribution utilities. A customer may apply to BCUC to leave the core market; such an application may be approved if it is demonstrated that the customer has adequate long-term natural gas supplies or alternative fuel supplies to protect him from supply interruptions. The non-core market is defined as all large industrial customers who elect to make their own natural gas supply arrangements and who can demonstrate to the BCUC sufficient long-term natural gas supply protection or alternative fuel capability to ensure security of the industry. Non-core market customers have full and open access to the competitive natural gas market. The British Columbia government will not apply its core market policy to other jurisdictions through Energy Removal Certificates

  3. Nuclear cardiology between echocardiography and coronary angiography in the management of CAD

    International Nuclear Information System (INIS)

    In managing coronary artery disease there are clearly posed questions: In diagnosis to assess presence, extent and severity of CAD, in therapy to assess prognosis and benefit of PTCA and ACVB. Coronary angiography remains the gold standard for assessing coronary stenosis, function imaging - stress echocardiography - and myocardial perfusion imaging (MIP) are assessing ischemia, i.e. extent and severity of CAD meaning prognosis and benefit of invasive therapy. The costs of echo /MPI/ catherization are 1 : 2: 6. When the essential conditions in non invasive investigations are observed - exact indication, maximal quality, evaluation of efficacy D, M and O - equal acceptance of all methods by cardiologists is attainable and there will be a great potential of cost saving in invasive diagnostics and therapy. The part of MPI is assessed in evaluating myocardium viability and benefit of invasive therapy, in the diagnosis of ischemia and evaluation of outcome MPI eventually will be replaced by stress echocardiography in future.

    Continued Interest in the use of iodine-1 23-labeled fatty acids for myocardial Imaging results from observations from a variety of studies that in many types of cardiac disease, regional fatty acid myocardial uptake patterns are often different than regional distribution of flow tracers. These differences may reflect alterations in important parameters of metabolism which can be useful for patient management or therapeutic strategy decision making. In addition, use of iodine-I 23-labeled fatty acid distribution may represent a unique metabolic probe to relate some aspects of the metabolism of these substrates with the regional viability of cardiac tissue. The use of such viability markers could provide important prognostic information on myocardial salvage, helping to identify patients for revascularization or angioplasty. Clinical studies are currently in progress with the iodine-123-labeled 1 5-(p-iodophenyl)-3-R,S-methylpentadecanoic acid (BMIPP) fatty acid analogue at several institutions. The goals of this paper are to discuss development of the concept of metabolic trapping of fatty acids, to briefly review development and evaluation of various radioiodinated methyl-branched fatty acids and to discuss recent patient studies with iodine-123 (BMIPP) using single photon emission computerized tomography (SPECT).

    D-SPECT (Spectrum Dynamics, Israel) is a novel SPECT system for cardiac perfusion studies. Based on CZT detectors, region-centric scanning, high-sensitivity collimators and resolution recovery, it offers potential advantages over conventional systems. A series of measurements were made on a β-version D-SPECT system in order to evaluate its performance in terms of energy resolution, scatter fraction, sensitivity, count rate capability and resolution. Corresponding measurements were also done on a conventional SPECT system (CS) for comparison. The energy resolution of the D-SPECT system at 140 keV was 5.5% (CS: 9.25%), the scatter fraction 30% (CS: 34%), the planar sensitivity 398 s-1 MBq-1 per head (99mTc, 10 cm) (CS: 72 s-1 MBq-1), and the tomographic sensitivity in the heart region was in the range 647-1107 s-1 MBq-1 (CS: 141 s-1 MBq-1). The count rate increased linearly with increasing activity up to 1.44 M s-1. The intrinsic resolution was equal to the pixel size, 2.46 mm (CS: 3.8 mm). The average reconstructed resolution using the standard clinical filter was 12.5 mm (CS: 13.7 mm). The D-SPECT has superior sensitivity to that of a conventional system with similar spatial resolution. It also has excellent energy resolution and count rate characteristics, which should prove useful in dynamic and dual radionuclide studies.

This article points to the importance of human capital (broadly defined) and the quality of the British labor force on the eve of the Industrial Revolution. It shows that in terms of both physical quality and mechanical skills, British workers around 1750 were at a much higher level than their continental counterparts. As a result, new inventions—no matter where they originated—were adopted earlier, faster, and on a la...

  18. The lebanese society of cardiology: plans and perspectives, navigating against contrary winds and progressing against all odds.

    Science.gov (United States)

    Kossaify, Antoine; Moussallem, Nicolas

    2014-01-01

    Scientific societies in medicine theoretically aim to improve a medical field as a science; however, this role is expanding nowadays to seeking also the improved practice of a certain medical field. In this regard, the current Lebanese Society of Cardiology (2013-2015) has laid many plans and considered many perspectives. These concern mainly, but not exclusively, the increase of public awareness regarding prevention, investment in research, implementation of guidelines, support of continuous medical education, organization of cardiology symposia and congresses, and achievement of national registries regarding main cardiac conditions, as well as the society's main objective of decreasing the burden of cardiovascular diseases in Lebanon. Nonetheless, the implementation of such plans and perspectives is facing contrary winds related to a multifaceted phenomenon: the dominance of private medicine with a subsequent lack of teamwork, the dominance of private media, the social and political unrest in Lebanon, significant discrepancies in the scientific background of cardiologists, and the absence of a standardized national cardiology licensing exam. Importantly, the implementation of such plans and perspectives requires individual commitment, along with the cooperation of the Order of Physicians, the Syndicate of Hospitals in Lebanon (representing private hospitals) and the Ministry of Health. Moreover, industry must be more committed to medical scientific societies; the support of cardiology events organized without the auspices of the Lebanese Society of Cardiology is not encouraged because of the presence of significant conflict of interest.

    Full Text Available The famous detective, Sherlock Holmes, once solved a case by referring to “the dog that did not bark.” In the past 250 years of British history, republicanism is another dog that did not bark. This is particularly true of supposedly our most radical major political party, the Labour Party. Over the monarchy, as over constitutional matters generally, Labour’s instincts have been conservative. Even after 1997, when the party, led by Lord Irvine, has indeed embarked upon major constitutional ref...

    This article will explore the image of the Royal Navy’s battleships in British society between 1920 and 1960. Although much of what follows might be said to apply to Royal Navy as a whole, particularly ‘glamorous’ vessels such as aircraft carriers, cruisers and destroyers, it is the contention of this piece that the Royal Navy’s battleships by virtue of their sheer size and power captured the public imagination more than any other type of warship. The study of the image of the battleship in p...

  3. Growing our business - the opportunities for nuclear in North America

    International Nuclear Information System (INIS)

    There is currently a growing belief from many quarters that nuclear power is undergoing something of a renaissance. British Energy is at the heart of nuclear power generation in the UK and is now looking to expand its business into the US, the largest electricity market in the world. Following a brief outline of where British Energy is at today, this paper goes on to discuss the company's future plans, not only in the UK but more particularly in the US, where sweeping deregulation has opened up possibilities for a company like British Energy to export its nuclear skills.

  4. Protection against ionizing radiation by leaded glass googles during interventional cardiology

    International Nuclear Information System (INIS)

    Background: It is not known whether leaded glass goggles with 0.25 mm Pb equivalency, used in interventional cardiology procedures, attenuate radiation below the levels established by the latest recommendation of the International Commission on Radiological Protection (ICRP). Aim: To assess if the degree of attenuation of the secondary ionizing radiation achieved by the use of 0.25 mm Pb leaded glass goggles, in occupationally exposed workers in interventional cardiology procedures, meets the latest ICRP recommendations. Material and Methods : A prospective investigation was carried out to compare the eye exposure to secondary ionizing radiation received by occupationally exposed personnel in a 9 months period. A set of two thermo luminescent dosimeters was arranged in the front and back of leaded glass goggles in a cohort of seven members of an interventional cardiology service, exposed to 1057 consecutive procedures. Results:The monthly dose equivalent measurement performed in front of the goggles ranged between 1.1 and 6.5 mSv,for paramedics and interventional cardiologists. The radiation measured in the back of the glass varied between 0.66 and 2.75 mSv,respectively.The degree of attenuation of the dose at eye level ranged from 40% to 57.7%,respectively. The projected annual exposure would reach 33 mSv for the interventional cardiologist. Conclusions: With a similar load of work and wearing 0.25 mm Pb equivalent glass goggles, interventional cardiologists will exceed the crystalline equivalent dose limit recommended by the ICRP (20 mSv/year averaged over the past 5 years)

    Full Text Available Abstract Background Carotid plaque severity and morphology can affect cardiovascular prognosis. We evaluate both the importance of echographically assessed carotid artery plaque geometry and morphology as predictors of death in hospitalised cardiological patients. Methods 541 hospitalised patients admitted in a cardiological division (age = 66 ± 11 years, 411 men, have been studied through ultrasound Duplex carotid scan and successively followed-up for a median of 34 months. Echo evaluation assessed plaque severity and morphology (presence of heterogeneity and profile. Results 361 patients showed carotid stenosis (67% with 70% stenosis, 4% with near occlusion and 2% with total occlusion. During the follow-up period, there were 83 all-cause deaths (15% of the total population. Using Cox's proportional hazard model, age (RR 1.06, 95% CI 1.03–1.09, p = 0.000, ejection fraction > 50% (RR = 0.62, 95% CI 0.4–0.96, p = 0.03, treatment with statins (RR = 0.52, 95% CI 0.29–0.95, p = 0.34 and the presence of a heterogeneous plaque (RR 1.6; 95% CI, 1.2 to 2.14, p = 0.002 were independent predictors of death. Kaplan – Meier survival estimates have shown the best outcome in patients without plaque, intermediate in patients with homogeneous plaques and the worst outcome in patients with heterogeneous plaques (90% vs 79% vs 73%, p = 0.0001. Conclusion In hospitalised cardiological patients, carotid plaque presence and morphology assessed by ultrasound are independent predictors of death.

    Pay-for-performance in German health care system is still uncommon but--in view of scheduled legislative projects--could gain more influence in future. Beside others, risc adjusted in-hospital mortality and the door-to-ballon-time inpatients with ST-elevation myocardial infarction could become quality- and performance indicators in interventional cardiology units. As a result, process optimization based on these indicators could have an impact on both patient value (as already today) and revenues (from 2017 onwards). PMID:26800075

    2011-07-15

    Radiation-guided procedures in interventional cardiology include diagnostic and/or therapeutic procedures, primarily coronary catheterization and coronary angioplasty. Application of the principles of radiation protection and the use of optimised procedures are contributing to dose reduction while maintaining the radiological image quality necessary for performance of the procedures. The mandatory training in patient radiation protection and technical training in the use of radiology devices mean that implementing continuous optimisation of procedures is possible in practice. This optimisation approach is the basis of patient radiation protection; when associated with the wearing of protective equipment it also contributes to the radiation protection of the cardiologists.

    2014-08-01

    Full Text Available The subjects of Owen Hatherley’s A Guide to the New Ruins of Great Britain are architecture and urban development. The book addresses also some broader cultural, political and economic references, as well as personal anecdotes and memories. It includes many encounters with the remnants of the British welfare state.As an extension to his blog postings and a sequel of sorts to his previous Militant Modernism, Hatherley’s antagonist here is the semi-official architecture of New Labour, which he terms ‘pseudomodernism’: an unimaginative, inferior, and, in its own specific way, also tacky architecture of white stucco, steel and glass. He attacks the Faustian bargain of Richard Rogers and his allies with neoliberalism, a pact that produces a modernism devoid of social content, reflected by the unimaginative, speculation-driven architectural design. While Hatherley produces the promised indictment of recent British architecture, the book is, at the end of the day, primarily a eulogy to the disappearing postwar architecture he so evidently loves.

    Full Text Available The purpose of this paper is to analyse a chart published by the British newspaper The Telegraphabout the most common misunderstandings foreigners face while making use of English as their second language. L2 speakers are said to take every word at face value and therefore making some pragmatic mistakes. Sometimes there can be another meaning behind the spoken words, like it is unsaid for a reason. The pragmatics theories of irony in Attardo (1999 shed light on these translating and intercultural awareness issues by explaining what is behind the misunderstanding which is the secret ofthe so famous British politeness. Some considerations will be made upon the chart so as to understand it, such as an analysis of irony and native speakers’ perspectives on it. In addition to that, we will take into account the opinion of some native speakers of English to unveil some details and clarify how meaningful some sentences may be and if the researched chart is actually accurate.

  15. On the use of DICOM cine header information for optimisation: Results from the 2002 European DIMOND cardiology survey

    International Nuclear Information System (INIS)

    The paper explores the level of information contained within the DICOM header in images from various cardiology systems. Data were obtained in the European DIMOND survey on image quality (Italy (Ireland)) (Belgium)) (Greece)) and Spain). Images from five standard diagnostic cardiology procedures carried out in six European hospitals have been analysed. DICOM header information was extracted to a database in order to analyse how it could help in the optimisation of the procedures. The level of data contained in the headers differs widely between cardiology systems. None of the X-ray systems in the 2002 survey archives the dosimetric data in the DICOM header. The mean number of runs per procedure ranges between 7.5 and 15.4 and the mean number of frames per procedure between 575 and 1417. Differences in kV p, mA, pulse time, distances and C-arm angulations are substantial and suggest that there exists a wide range for optimisation. (authors)

  16. British Asians, Covert Racism and Exclusion in English Professional Football

    Directory of Open Access Journals (Sweden)

    2013-12-01

    Full Text Available This article examines the exclusion of British Asians from English professional football. At present, there are eight British Asians with professional contracts out of over 4,000 players. This statistic is increasingly noteworthy when we consider that, first, football is extremely popular across British Asian groups and, second, Britain is home to over 4 million British Asians (the UK’s largest minority ethnic group. Following a brief introduction as well as a discussion of racisms, the work will provide an overview of the barriers that have excluded British Asian football communities from the professional ranks. In particular, I shall discuss some of the key obstacles including overt racism, ‘all-Asian’ football structures and cultural differences. However, the focus of this paper is to explore the impact and persist-ing nature of institutional racism within football. With the aid of oral testimonies, this work shall present British Asian experiences of covert racism in the game. I shall therefore demonstrate that coaches/scouts (as gatekeepers have a tendency to stereotype and racialize British Asian footballers, thus exacerbating the British Asian football exclusion. Finally, the article will offer policy recommendations for reform. These recommendations, which have come out of primary and secondary research, aspire to challenge institutional racism and combat inequalities within the game.

    Kyriakides, Christopher; Virdee, Satnam

    2003-11-01

    This study explores the dynamics of racism, specifically its generation and reproduction as an ideology, and its role in affecting the reception and occupational location of migrant medical labour in Britain. It is argued that the treatment of 'overseas doctors' in Britain draws on a complex interplay between racism and nationalism underpinned by the historical construction of 'welfarism' as a moral legitimator of 'Britishness'. Through an exploration of internal and external immigration controls introduced with the aim of regulating migrant labour, we demonstrate how British social policy and elite discourses of 'race' combine to construct moral prescriptions of threat such that migrants and British-born 'non-whites' entering the British medical profession are forced to negotiate 'saviour/pariah' ascriptions indicative of discriminatory but contradictory processes specific to the operation of the British National Health Service as a normative institution.

  3. Influence of Ceiling Suspended Screen Positioning to the Scatter Radiation Levels in Interventional Cardiology

    International Nuclear Information System (INIS)

    The objective of this paper is to identify the effects of the ceiling suspended screen position to the scatter radiation levels in the interventional cardiology. The scatter radiation in terms of ambient dose equivalent H*(10) was measured for various positions of protective screen in the positions of the first operator, nurse and radiographer, at elevations 100-190 cm and in four different angulations of the x-ray tube. To assess the effectiveness of the protective screen, the scattered dose was also measured in the absence of any protection in all four angulations and elevations. To simulate real clinical situation the measurements were performed in the presence of 30 cm PMMA phantom using standard clinical protocol. The utility of protective screen varied for different positions and angulations. Scatter radiation levels varied in the range 70 - 3400 μSv/h for the first operator, 140 - 3200 μSv/h for the nurse and 50 - 560 μSv/h for radiographer. Ceiling suspended screens can provide a substantial level of protection (up to factor 18) in interventional cardiology, but they have to be properly managed and positioned to achieve sufficient level of protection. The guidance for optimal protection is provided in the paper.(author)

  4. Kerma rate evaluation in the air in a room interventional cardiology

    International Nuclear Information System (INIS)

    In recent years, the number of interventional cardiology procedures is increasing. However, due to the long time of fluoroscopy in these procedures, care teams can receive high doses of radiation. The radiation scattered by the patient is not uniform, and their assessment is of utmost importance. This study aimed to estimate and map the kerma rate in the air at the time of the gonads, in an interventional cardiology room, seeking to optimize the dose absorbed by individuals occupationally exposed to ionizing radiation. For data collection, the room was divided into quadrants of 1m2, totaling 40 collection points. The simulator was positioned so that its entry surface was located in the interventional reference point. Were chosen the conditions that simulate angiography and angioplasty procedures performed in the service. The data were obtained for height of 1 meter, gonad region. The results obtained for kerma rates in air, in quadrants, show that higher measured values was in the vicinity of the X-ray tube. Has been found that the medical staff are more exposed, because of its location during the procedure, around the table. The law of the inverse square distance of the farthest points of the X-ray tube were verified

    The equivalent dose limit for the eye lens for occupational exposure recommended by the ICRP has been reduced to 20 mSv y(-1) averaged over defined periods of 5 y, with no single year exceeding 50 mSv. The compliance with this new requirement could not be easy in some workplace such as interventional radiology and cardiology. The aim of this study is to evaluate different possible approaches in order to have a good estimate of the eye lens dose during interventional procedures. Measurements were performed with an X-ray system Philips Allura FD-10, using a PMMA phantom to simulate the patient scattered radiation and a Rando phantom to simulate the cardiologist. Thermoluminescence (TL) whole-body and TL eye lens dosemeters together with Philips DoseAware active dosemeters were located on different positions of the Rando phantom to estimate the eye lens dose in typical cardiology procedures. The results show that, for the studied conditions, any of the analysed dosemeter positions are suitable for eye lens dose assessment. However, the centre of the thyroid collar and the left ear position provide a better estimate. Furthermore, in practice, improper use of the ceiling-suspended screen can produce partial protection of some parts of the body, and thus large differences between the measured doses and the actual exposure of the eye could arise if the dosemeter is not situated close to the eye.

  6. Paediatric interventional cardiology: flat detector versus image intensifier using a test object

    International Nuclear Information System (INIS)

    Entrance surface air kerma (ESAK) values and image quality parameters were measured and compared for two biplane angiography x-ray systems dedicated to paediatric interventional cardiology, one equipped with image intensifiers (II) and the other one with dynamic flat detectors (FDs). Polymethyl methacrylate phantoms of different thicknesses, ranging from 8 to 16 cm, and a Leeds TOR 18-FG test object were used. The parameters of the image quality evaluated were noise, signal-difference-to-noise ratio (SdNR), high contrast spatial resolution (HCSR) and three figures of merit combining entrance doses and signal-to-noise ratios or HCSR. The comparisons showed a better behaviour of the II-based system in the low contrast region over the whole interval of thicknesses. The FD-based system showed a better performance in HCSR. The FD system evaluated would need around two times more dose than the II system evaluated to reach a given value of SdNR; moreover, a better spatial resolution was measured (and perceived in conventional monitors) for the system equipped with flat detectors. According to the results of this paper, the use of dynamic FD systems does not lead to an automatic reduction in ESAK or to an automatic improvement in image quality by comparison with II systems. Any improvement also depends on the setting of the x-ray systems and it should still be possible to refine these settings for some of the dynamic FDs used in paediatric cardiology.

  7. Evaluation of doses to staff involved in interventional cardiology in two Khartoum hospitals

    International Nuclear Information System (INIS)

    In interventional cardiac procedures, staff operates near the patient in a non-uniformly scattered radiation field. Consequently, workers may receive, over a period of time, relatively high radiation doses. The measurement of individual doses to personnel becomes critical due to the use of protective devices and, as a consequence of the large number of methods proposed to assess the effective dose, In this study, staff doses were measured in two cardiac centers: Ahmed Gasim Hospital and Cardiac Center, Khartoum. The objective was to measure personal dose equivalent and accordingly estimate the effective dose which is received by staff in interventional cardiology. Measurements were performed using electronic personal dosimeters (EPDs) worn over lead apron during the examination and were read immediately following each examination. A total number of 40 radiation worker were monitored for a period of two weeks. The highest doses received by the cardiologist followed by nurses and then X-ray technicians. Staff received mean effective doses that ranged from 24 to 110 μSv estimated for four weeks. Recommendations on how to reduce staff doses in interventional cardiology are presented. (Author)

  8. Pulse waveform analysis as a bridge between pulse examination in Chinese medicine and cardiology.

    de Sá Ferreira, Arthur; Lopes, Agnaldo José

    2013-04-01

    Pulse examination was probably the earliest attempt to distinguish between health and illnesses. Starting at the pre-Hippocratic era, Chinese medicine practitioners developed techniques for pulse examination and defined pulse images based on their perceptions of pulse waveforms at the radial artery. Pulse images were described using basic variables (frequency, rhythm, wideness, length, deepness, and qualities) developed under philosophical trends such as Taoism and Confucianism. Recent advances in biomedical instrumentation applied to cardiology opened possibilities to research on pulse examination based on ancient Chinese medical theories: the pulse wave analysis. Although strongly influenced by philosophy, some characteristics used to describe a pulse image are interpretable as parameters obtained by pulse waveform analysis such as pulse wave velocity and augmentation index. Those clinical parameters reflect concepts unique to Chinese medicine - such as yinyang - while are based on wave reflection and resonance theories of fluids mechanics. Major limitations for integration of Chinese and Western pulse examination are related to quantitative description of pulse images and pattern differentiation based on pulse examination. Recent evidence suggests that wave reflection and resonance phenomena may bridge Chinese medicine and cardiology to provide a more evidence-based medical practice. PMID:23546634

    @@ Nonvalvular atrial fibrillation (NVAF) is the most common sustained cardiac arrhythmia in clinical practice, which if untreated results in a doubling of cardiovascular morbidity and mortality. AF is an independent predictor of stroke, with an annual risk 5 to 6 times higher than patients in sinus rhythm.1 During recent years, several randomised clinical trials conducted by investigators around the world involving 13 843 participants with NVAF have demonstrated convincingly the value of warfarin therapies for stroke prevention in high risk patients.2-8 However, the dose response of warfarin is complex and its activity is easily altered by concurrent medications, food interactions, alcohol and illnesses. Adherence to medical advice and routine monitoring of the international normalized ratio (INR) is important, because low anticoagulant intensity predisposes the patients to thromboembolic complications and high intensity to haemorrhage. Studies suggested that anticoagulant clinics could improve the quality of anticoagulation control,9 and anticoagulant clinics are common in western countries. However, in China, most AF patients taking warfarin usually attend the outpatient clinic of cardiology, while the quality of anticoagulation control is never investigated. We therefore assessed anticoagulation control in the outpatient clinic of cardiology, and the quality of anticoagulation control since the establishment of anticoagulant clinics.

Results Of the 60 CMR centres identified, 88% responded to a detailed questionnaire. Services are led by cardiologists and radiologists in equal proportion, though the majority of current trainees are cardiologists. The mean number of CMR scans performed annually per centre increased by 44% over two years. This trend was consistent across centres of different scanning volumes. The commonest indication for CMR was assessment of heart failure and cardiomyopathy (39%, followed by coronary artery disease and congenital heart disease. There was striking geographical variation in CMR availability, numbers of scans performed, and distribution of trainees. Centres without on site scanning capability refer very few patients for CMR. Just over half of centres had a formal training programme, and few performed regular audit. Conclusion The number of CMR scans performed in the UK has increased dramatically in just two years. Trainees are mainly located in large volume centres and enrolled in cardiology as opposed to radiology training programmes.

  13. Australia's nuclear graveyard

    International Nuclear Information System (INIS)

    Britain and Australia have become locked in a battle of wills and wits over a nuclear legacy that is now more than 30 years old. At stake is the issue of who will pay to clean up a stretch of the central Australian outback where at least 23 kilograms of plutonium are buried in nuclear graveyards or scattered in fine particles on the ground. The plutonium was left there after a series of British nuclear weapons tests in the 1950s and 1960s. The cost of cleaning it up today, and rendering the ground safe the the Aborigines who claim it as their tribal homeland, has been estimated at up to $158 million. Australia's minister for resources, Senator Gareth Evans, went to London in October 1986 to try to involve the British in the cleanup. But Britain is still taking the stand that it had discharged any obligations on this score long ago. This question is at the heart of controversy that began mounting in the late 1970s over the British nuclear tests. It was then that Aborigines and test veterans from Britain and Australia started alleging that they had been exposed to unduly high doses of radiation. Clearly, the nuclear tests, which began as a political exercise between Britain and Australia more than 30 years ago, seem destined to remain the source of much legal, diplomatic, and financial fallout between the two countries for a long time to come

    Britain's race for Africa continues to draw significant scholarly interest. Traditionally, studies have focused on well-documented figures such as explorers, missionaries and capitalists. Working against the trend, this is the first book to concentrate solely on the role of engineers. It analyses...... the imperial diasporas, identities and networks that developed as the British engineering profession established connections on the African continent. Using a wide range of primary sources that include correspondence, diaries, technical reports, institutional minutes and periodicals, Andersen...... reconstructs the networks and activities of Britain's engineers while focusing on London as a centre of imperial expansion. By treating Britain and the empire as an interconnected zone heanalyses the ways in whichideas , people and technologies circulated during the critical period....

    American English(AmE)is the form of English used in the United States.It includes all English dialects used within the United States. British English(BrE)is.the form of English used in the United Kingdom. It includes all English dialects used within the United Kingdom. Language is a part of culture, and it plays an important role in culture. Language reflects the characteristic of a nation. It not only includes the history and cultural background of a nation, but also fosters the nation ’s attitudes towards life, and ways of living and thinking of the nation. Therefore, to my point of view, the cause of language differences is basically the differences between cultures.

    GM2 gangliosidosis (Tay-Sachs disease) was diagnosed in 6- to 8-month-old pedigree Jacob lambs from two unrelated flocks presenting clinically with progressive neurological dysfunction of 10 day's to 8 week's duration. Clinical signs included hindlimb ataxia and weakness, recumbency and proprioceptive defects. Histopathological examination of the nervous system identified extensive neuronal cytoplasmic accumulation of material that stained with periodic acid--Schiff and Luxol fast blue. Electron microscopy identified membranous cytoplasmic bodies within the nervous system. Serum biochemistry detected a marked decrease in hexosaminidase A activity in the one lamb tested, when compared with the concentration in age matched controls and genetic analysis identified a mutation in the sheep hexa allele G444R consistent with Tay-Sachs disease in Jacob sheep in North America. The identification of Tay-Sachs disease in British Jacob sheep supports previous evidence that the mutation in North American Jacob sheep originated from imported UK stock. PMID:24309906

  17. Net metering in British Columbia : white paper

    International Nuclear Information System (INIS)

    Net metering was described as being the reverse registration of an electricity customer's revenue meter when interconnected with a utility's grid. It is a provincial policy designed to encourage small-distributed renewable power generation such as micro-hydro, solar energy, fuel cells, and larger-scale wind energy. It was noted that interconnection standards for small generation is an important issue that must be addressed. The British Columbia Utilities Commission has asked BC Hydro to prepare a report on the merits of net metering in order to support consultations on a potential net metering tariff application by the utility. This report provides information on net metering with reference to experience in other jurisdictions with net metering, and the possible costs and benefits associated with net metering from both a utility and consumer perspective. Some of the barriers and policy considerations for successful implementation of net metering were also discussed. refs., tabs., figs

  1. Fetal cardiology

    International Nuclear Information System (INIS)

    Doppler echocardiography makes it possible to diagnose congenital heart disease in early pregnancy. It allows us to study the anatomical configuration of the fetal heart, and additionally, to evaluate the physiological conditions of the fetus. Evaluation of the direction, velocity, wave form pattern, and quantification of blood flow at the various sites in the fetal heart helps us to assess the characteristics of the fetal circulation and condition of the fetal heart. In order to use this technique in pathological situations, an initial study of the developing normal human fetal circulation was necessary. The authors studied 34 uncomplicated pregnancies by serial Doppler echocardiography. The studies were performed every 4 weeks from 16-weeks gestation to term. The pulsed Doppler sector scanner provided cardiac cross-sectional images, mitral and tricuspid blood velocities were obtained from apical four-chamber views. Angle corrected maximal and mean temporal velocities were calculated by digitizing the Doppler frequency shift recording on a graphic tablet computed with a minicomputer. The angle between the Doppler interrogation beam and the direction of blood flow was kept as small as possible in order to minimize the error

  3. Nuclear medicine

    International Nuclear Information System (INIS)

    Except for dedicated devices for mobile nuclear cardiology for instance, the market is set on variable angulation dual heads cameras. These cameras are suited for all general applications and their cost effectiveness is optimized. Now, all major companies have such a camera in their of products. But, the big question in nuclear medicine is about the future of coincidence imaging for the monitoring of treatments in oncology. Many companies are focused on WIP assessments to find out the right crustal thickness to perform both high energy FDG procedures and low energy Tc procedures, with the same SPECT camera. The classic thickness is 3/8''. Assessments are made with 1/2'', 5/8'' or 3/4'' crystals. If FDG procedures proved to be of great interest in oncology, it may lead to the design of a dedicated SPECT camera with a 1'' crustal. Due to the short half of FDG, it may be the dawning of slip ring technology. (e.g. Varicam from Elscint). The three small heads camera market seems to be depressed. Will the new three large heads camera unveiled by Picker, reverse that trend? The last important topic in nuclear medicine is the emergence of new flat digital detectors to get rid of the old bulky ones. Digirad is the first company to manufacture a commercial product based on that technology. Bichron, Siemens and General Electric are working on that development, too. But that technology is very expensive and the market for digital detection in nuclear medicine is not as large as the market in digital detection in radiology. (author)

    Analysis of the makeup and contributions of the British contingents to the first two Solvay Councils can elucidate the character of British mathematical physics and its internal dynamics at a critical time in its development. The paper provides this analysis, outlines the process of selection of the participants, parses the meaning of "international" in the Solvay context, and offers an explanation of the differential attendance of the British at the two Councils. Most of those invited to the first refused whereas all but one of those invited to the second accepted. The unusual social and scientific views of Ernest Solvay help to explain this divergence.

  9. The action of NGOs in the field of disarmament (between ambitions and limitations) and the British example

    International Nuclear Information System (INIS)

    The author first tries to characterize the various NGOs committed in the struggle for disarmament (countries of origin, size, organisation, ties with a political party or a trade union, typology). Then, by addressing different aspects of disarmament (anti-personnel mines, extraordinary sessions of the UN General Assembly dedicated to disarmament, Freeze campaign, or the National Missile Defense), the author identifies and discusses the various strengths and failures of NGOs in their ability to influence the States diplomatic activity or in their legitimacy to intervene. In a second part, the author more particularly addresses the British example. He proposes a sociological analysis of British NGOs (occurrence of the words 'peace' and 'nuclear' in their names, religious or professional dimension), and briefly presents some of them (Acronym Institute, British American Security Information Council, International Security Information Service - UK, Vertic, Programme for Promoting the nuclear non-proliferation or PPNN, Pugwash, Campaign for Nuclear Disarmament, Labour Action for Peace). He comments the evolution of the Labour Party into the New Labour created by Tony Blair

    Objectives To determine the association between cardiology consultation and evidence-based care for nursing home (NH) residents with heart failure (HF). Participants Hospitalized NH residents (n= 646) discharged from 106 Alabama hospitals with a primary discharge diagnosis of HF during 1998–2001. Design Observational. Measurements of Evidence-Based Care Pre-admission estimation of left ventricular ejection fraction (LVEF) for patients with known HF (n=494), in-hospital LVEF estimation for HF patients without known LVEF (n=452), and discharge prescriptions of angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (ACEIs-or-ARBs) to systolic HF (LVEF 100 mm Hg. Results Pre-admission LVEF was estimated in 38% and 12% of patients receiving and not receiving cardiology consultation, respectively (adjusted odds ratio {AOR}, 3.49; 95% CI, 2.16–5.66; p <0.001). In-hospital LVEF was estimated in 71% and 28% of patients receiving and not receiving cardiology consultation, respectively (AOR, 6.01; 95% CI, 3.69–9.79; p <0.001). ACEIs-or-ARBs were prescribed to 62% and 82% of patients receiving and not receiving cardiology consultation, respectively (AOR, 0.24; 95% CI, 0.07–0.81; p=0.022). Conclusion In-hospital cardiology consultation was associated with significantly higher odds of LVEF estimation among NH residents with HF. However, it did not translate into higher odds of discharge prescriptions for ACEIs-or-ARBs to NH resident with systolic HF who were eligible for the receipt of these drugs. PMID:21982687

    Nuclear Cardiology for the past 40 years has distinguished itself in its ability to non-invasively assess regional myocardial blood flow and identify obstructive coronary disease. This has led to advances in managing the diagnosis, risk stratification, and prognostic assessment of cardiac patients. These advances have all been predicated on the collection of high quality nuclear image data. National and international professional societies have established guidelines for nuclear laboratories to maintain high quality nuclear cardiology services. In addition, laboratory accreditation has further advanced the goal of the establishing high quality standards for the provision of nuclear cardiology services. This article summarizes the principles of nuclear cardiology single photon emission computed tomography (SPECT) and positron emission tomography (PET) imaging and techniques for maintaining quality: from the calibration of imaging equipment to post processing techniques. It also will explore the quality considerations of newer technologies such as cadmium zinc telleride (CZT)-based SPECT systems and absolute blood flow measurement techniques using PET. PMID:23868070

  14. Assessment of the occupational exposure in real time during interventional cardiology procedures

    International Nuclear Information System (INIS)

    Interventional cardiology (IC) procedures can be complex, requiring the operators to work near the patient, during long exposure times. Owing to scattered radiation in the patient and the fluoroscopic equipment, the medical staff are exposed to a nonuniform radiation field and can receive high radiation doses. In this study, it is proposed to analyse staff doses obtained in real time, during IC procedures. A system for occupational dosimetry in real time was used. In order to identify some parameters that may affect the staff doses, Monte Carlo (MC) calculations, using MCNPX v.2.7.0 code and voxel phantoms, were performed. The data obtained from measurements, together with MC simulations, allowed the identification of actions and behaviours of the medical staff that could be considered a risk under routine working conditions. The implementation of this monitoring system for exposure of personnel may have a positive effect on optimisation of radiological protection in fluoroscopically guided cardiac procedures. (authors)

  16. Performance of several active personal dosemeters in interventional radiology and cardiology

    International Nuclear Information System (INIS)

    Active personal dosemeters (APDs) are very useful instruments for optimizing radiation protection of workers and for increasing worker’s awareness of unexpected exposures. The challenge of monitoring personal equivalent doses with APDs in interventional fluoroscopy is that they must be sensitive to low energy photon beams and be able to record high dose rates. The aim of this work is to verify both the performance and the reliability of four active personal dosemeters (APDs) and one direct ion storage (DIS) dosemeter in typical X-ray radiation fields used during interventional radiology and cardiology (IR/IC) procedures. The values of the personal dose equivalent at a depth of 10 mm measured by the APDs are compared with the response of a whole body thermoluminescence dosemeter (TLD) as a reference dosemeter. The response is found to be satisfactory in the tested situations.

  17. Measurements of eye lens doses in interventional radiology and cardiology: Final results of the ORAMED project

    International Nuclear Information System (INIS)

    Within the ORAMED project (Optimization of Radiation Protection of Medical Staff) a coordinated measurement program for occupationally exposed medical staff was performed in different hospitals in Europe ( (www.oramed-fp7.eu)). The main objective was to obtain a set of standardized data on extremity and eye lens doses for staff involved in interventional radiology and cardiology and to optimize radiation protection. Special attention was given to the measurement of the doses to the eye lenses. In this paper an overview will be given of the measured eye lens doses and the main influence factors for these doses. The measured eye lens doses are extrapolated to annual doses. The extrapolations showed that monitoring of the eye lens should be performed on routine basis.

    The eye lens annual dose limit for exposed personnel to ionizing radiation has recently been revised by the ICRP--International Commission on Radiological Protection and the proposed new limit has been accepted by European legislation through the Council Directive 2013/59/EURATOM 2013. Among medical exposed personnel, the staff performing interventional cardiology are usually affected by relevant doses. For this reason a survey, employing dosemeters characterized in terms of H(p)(3), was performed in order to get the order of magnitude of the doses received by the eye lens, at least as a first guess.The survey showed that the annual dose limit can easily be reached if a proper radiation protection approach is not implemented.

    The purpose of this paper is to test the appropriateness of OSL and electronic dosemeters to estimate eye lens doses at interventional cardiology environment. Using TLD as reference detectors, personal dose equivalent was measured in phantoms and during clinical procedures. For phantom measurements, OSL dose values resulted in an average difference of -15 % vs. TLD. Tests carried out with other electronic dosemeters revealed differences up to ±20 % versus TLD. With dosemeters positioned outside the goggles and when TLD doses were >20 μSv, the average difference OSL vs. TLD was -9 %. Eye lens doses of almost 700 μSv per procedure were measured in two cases out of a sample of 33 measurements in individual clinical procedures, thus showing the risk of high exposure to the lenses of the eye when protection rules are not followed. The differences found between OSL and TLD are acceptable for the purpose and range of doses measured in the survey. PMID:24464819

    The treatment of cardiovascular disease has changed dramatically over the past 2 decades, allowing patients to live longer and better quality lives. The introduction of new therapies has contributed much to this success. Nowhere has this been more evident than in interventional cardiology, where percutaneous cardiovascular intervention has evolved in the past 2 decades from a quirky experimental procedure to a therapeutic cornerstone for patients with symptomatic cardiovascular disease. The development of these technologies from the earliest stages requires preclinical experiments using animal models. Once introduced into the clinical arena, an understanding of therapeutic mechanisms of these devices can be ascertained through comparisons of animal model research findings with clinical pathological specimens. This review provides an overview of the emerging role, results of preclinical studies and development, and evaluation of animal models for percutaneous cardiovascular intervention technologies for patients with symptomatic cardiovascular disease.

  2. Evaluation of occupational and medical doses on interventional cardiology procedures by Monte Carlo method

    International Nuclear Information System (INIS)

    Interventional cardiology consists on a set of medical procedures which are mainly focused on diagnosing and treating patients who suffer cardiovascular diseases. Even though the usage of X-ray is justified on this case, it is greatly advised to evaluate the dose which professionals and patients will be exposed due to the fact that the complexity and length of the procedures often require high doses. The objective of this work is to estimate the radiation dose on both a patient and a physician through conversion coefficient (CCs) of effective dose (E) and equivalent dose (H) during a coronary angiography examination.The dose CCs was estimated using the Visual Monte Carlo code (VMC) and a pair of simulators anthropomorphic voxel (Female Adult VoXel). The CCs were normalized in terms of kerma-area product (KAP). As expected, for all situations studied, the patient in anteroposterior projection (AP) obtained the highest conversion coefficient of equivalent dose and effective dose (author)

  4. Skin Dose to Patients from Interventional Radiology and Cardiology Procedures with Potentially Long Fluoroscopy Times

    International Nuclear Information System (INIS)

    The increasing frequency and complexity of interventional procedures means that there is an increasing potential for the patient to suffer radiation-induced skin injuries. Dose measurements were initiated in a number of radiology, neuroradiology and cardiology departments in the Northern Ireland region carry out interventional procedures with potentially long fluoroscopy times. The intention was to measure patient skin dose and thus estimate the likelihood of deterministic effects occurring from such examinations. For each patient, several thermoluminescence dosemeters were placed on the areas of skin the radiologist or cardiologist considered were most likely to receive the greatest irradiation. Results are presented which indicate that several types of procedure have the potential to produce deterministic effects to patients' skin. It was concluded that skin dose should be routinely measured for each patient undergoing an interventional radiology procedure which has potentially a long fluoroscopy time. (author)

    The holistic concept of health, popularization of knowledge, as well as social and economic factors have contributed to the growing interest in research concerning quality of life in cardiovascular diseases. The value of direct measurements of the patient's well-being and the extent of their functioning in everyday life (i.e., health-related quality of life; HRQoL) has gained appreciation. Questionnaires are the most popular method of measuring quality of life. On the basis of the literature, we can conclude that the Short-Form Health Survey (SF-36) questionnaire is one of the most widely used tools measuring the quality of life of patients undergoing cardiological treatment and cardiac surgery.

    Full Text Available Cardiopulmonary exercise testing is a method used to assess the exercise capacity. It is used in cardiology to define the diagnostic and prognostic information, the treatment and its effectiveness. This method is also useful in sport medicine and in occupational medicine. The cardiopulmonary exercise test involves measuring of gas exchange during exercise testing. The article presents the main parameters assessed during the test and the indications and contraindications for conducting the test. It also reveals the results of recently published clinical trials on the use of cardiopulmonary exercise test in patients with cardiovascular disease and in the working population. The study included variability of respiratory parameters during the cardiopulmonary exercise test and after its completion, as well as their impact on the prognostic value. In addition, the results of a study involving an optimal choice of interval training on the basis of oxygen consumption at peak exercise are summarized. Med Pr 2014;65(5:665–674

  8. Monitoring of doses to patients in interventional cardiology: first results from three Serbian hospitals

    International Nuclear Information System (INIS)

    The aim of this work is to assess level of radiation dose to patients in interventional cardiology procedures in three large Serbian hospitals and to investigate possibility for setting of trigger levels if dose quantities exceed certain levels. Three dedicated interventional cardiology laboratories were included in the survey. Information on annual workload was estimated based on number of coronary angiography (CA) procedures and percutaneous coronary interventions (PCI). Patients doses were assessed in terms of air kerma area product (PKA) and air kerma in international reference point (KIRP). Results were compared with internationally proposed Diagnostic Reference Levels (DRL) and similar surveys results. Average total annual number of procedures was 820, 1100 and 2500 in three hospitals, respectively, while total number of dose measurements was 337. All three centers reported PKA values higher than 100 Gy·cm2 and even values above 200 Gy·cm2, corresponding to 42% and 16% of all measurements. Measured KIRP value higher than 5 Gy was reported in one center, indicating that skin doses associated possibility of skin injuries were observed. PKA mean hospital values for CA ranged from 33 to 78 Gy·cm2 and for PCI from 73 to 113 Gy·cm2, while associated vales for KIRP were: 0.45-1.2 Gy and 1.1-1.8 Gy, respectively. Comparison of obtained results with international DRL indicated that significant number of procedures is not optimally performed as in some centers more than a half of patients receive doses above DRL. The presented results are valuable input for dose optimization strategies and increased awareness related to importance of dose management. With respect to high dose values, risk for stochastic effects and tissue reactions, dose management methods were proposed. (Author)

  9. Patient dose assessment in various Interventional radiology and cardiology procedures in Algeria (IAEA regional project results)

    Full text: Purpose: To evaluate patient doses in Interventional Radiology (IR) and Cardiology (IC) procedures in Algeria, within the framework of an International Atomic Energy Agency (IAEA) regional project on radiation protection of patients and medical exposure control (RAF 9033). Materials and Methods: Three public hospitals (CHU Bab el Oued, CHU Parnet and CHU Mustapha) and one specialised Cardiology Service (Clinique Maouche) were chosen for the study. For Maximum Skin Dose (MSD) evaluation, gafchromic films XR type R were used, placed on patient's back before the procedure. The Dose Area Product (DAP) and MSD were measured in 57 IR and IC procedures, either diagnostic or therapeutic. Results: The results revealed large variations in MSD (0.06-3.3 Gy) and DAP (5.5-332 mGycm2). Mean MSD was 0.227 Gy in cerebral angiography, 0.202 Gy in coronary angiography, 1.162 Gy in Percutaneus Transluminal Coronary Angioplasty (PTCA) and 0.128 in abdominal angiography. The correlation of DAP and MSD was significant (r = 0.7). The correlation was DAP and fluoroscopy time was also significant (r = 0.8). Conclusion: The highest MSD values were found in PTCA which is a therapeutic procedure. Two PTCAs out of the 57 procedures measured in total had MSD over the threshold of 2 Gy for deterministic effects (MSD1 = 3.0 Gy and MSD2 3.3 Gy). The large variations in MSD reveal the need to continuously monitor patient doses in IR and IC procedures with special emphasis in PTCA procedure. (author)

  10. Provision of Transition Education and Referral Patterns from Pediatric Cardiology to Adult Cardiac Care.

    ACC/AHA guidelines recommend a structured preparation for and transfer to adult-oriented cardiac care for adult survivors of pediatric onset heart disease (POHD). Given this, we sought to describe the transition and transfer practices for a cohort of young adults with POHD and to determine factors associated with successful transfer to adult-oriented cardiac care. We performed a single-center, retrospective chart review on patients ≥18 years of age, with POHD likely to require lifelong cardiac care, who were seen in outpatient pediatric cardiology (PC) between 2008 and 2011. Successful transfer was defined as the subsequent attendance at adult cardiology (AC) within 2 years of PC visit. We identified 118 patients who met study criteria. Mean age 22.4 ± 2.0 years, 59 % male, 64 % white and 40 % Hispanic. Mean transition education topics noted was 3.3 ± 1.8 out of 20 and covered the underlying cardiac disease (89 %), follow-up and current medications (56 %) and exercise limitations (34 %). Recommendations for follow-up were AC (57 %) and PC (33 %). Of those told to transfer to AC, 79 % successfully transferred. Characteristics of successful transfer included: prior cardiac surgery (p = 0.008), cardiac medication use (p = 0.006) and frequency of follow-up ≤1 year (p = 0.037). One-quarter of all subjects did not follow-up within at least 2 years. Despite published guidelines, transition education appears lacking and the approach to transfer to adult cardiac care is not consistent. Given the increased risk of morbidity and mortality in this patient population, standardization of transition education and transfer processes appear warranted. PMID:26385471

    Abstract Problem Providing health care for children with congenital heart diseases remains a major challenge in low- and middle-income countries. Approach In October 2011, the Government of Paraíba, Brazil, established a paediatric cardiology network in partnership with the nongovernmental organization Círculo do Coração. A cardiology team supervised all network activities, using the Internet to keep in contact with remote health facilities. The network developed protocols for screening heart defects. Echocardiograms were performed by physicians under direct online supervision of a cardiologist; alternatively, a video recording of the examination was subsequently reviewed by a cardiologist. Cardiovascular surgeons came to a paediatric hospital in the state capital once a week to perform heart surgeries. Local setting Until 2011, the State of Paraíba had no structured programme to care for children with heart disease. This often resulted in missed or late diagnosis, with adverse health consequences for the children. Relevant changes From 2012 to 2014, 73 751 babies were screened for heart defects and 857 abnormalities were identified. Detection of congenital heart diseases increased from 4.09 to 11.62 per 1000 live births (P Internet. Time to diagnosis, transfers and hospital stays were greatly reduced. A total of 330 operations were carried out with 6.7% (22/330) mortality. Lessons learnt Access to an echocardiography machine with remote supervision by a cardiologist improves the detection of congenital heart disease by neonatologists; virtual outpatient clinics facilitate clinical management; the use of Internet technology with simple screening techniques allows resources to be allocated more efficiently.

Its main indications are`s cardioversion and defibrillation. The electrical shock therapy follows laws of electricity laws and consequently, its main difficulty is the impedance or resistance of electrons flow. To make better the effectiveness of this therapy, a number of improvements have been made on the shock wave, its duration, and polarity. The electric shock therapy has become the preferred treatment when dealing with cardiorespiratory arrest secondary, ventricular fibrillation and pulseless ventricular tachycardia. Similarly, it is the preferred treatment for ventricular tachyarrhythmia associated with hemodynamic compromise. Despite its significant advantages, this treatment causes secondary effects, which should adequately be known in order to provide a timely treatment.

  6. Submission to the British Columbia government on the Kyoto Protocol

    International Nuclear Information System (INIS)

    The Business Council provided its comments concerning the Kyoto Protocol and climate change to the government of British Columbia, recommending that a clear position be established quickly on the matter. The adopted position should also be disseminated broadly to allow stake holders sufficient time to prepare for the upcoming meetings of the Joint Ministers and First Ministers. The federal government has announced that the decision on whether to ratify the Kyoto Protocol will be made before the end of 2002, and this decision will have numerous effects on the people of British Columbia, businesses, workers, and consumers alike. The Business Council of British Columbia believes that the unique interests of the province can best be protected by a proactive approach. Actions plans are being prepared by several of the other provinces and territories, who have already stated their position concerning the Kyoto Protocol. The long-term risks of climate change for British Columbia have not been determined nor have the elements of a provincial approach. The following elements should be included in British Columbia's position on the Kyoto Protocol, according to the Business Council of British Columbia: (1) a credible and cost-effective implementation plan that does not unduly burden the province and other jurisdictions must be developed before Canada decides to ratify the Protocol. British Columbia should go on the record stating it does not support the ratification of the Kyoto Protocol in its present form. (2) the province should advocate for a national approach to climate change that can be achieved within a reasonable time frame, reflects the long-term nature of the problem, and is in agreement with the economic development objectives of British Columbia, (3) a plan detailing how the province intends to deal with the growth of greenhouse gas emissions should supplement and support the position of the province on the Kyoto Protocol.

    Two experimental nestbox trials were attempted, which aimed to maximise uptake by Marsh Tits in British woodland. Nestboxes which more closely approximated the dimensions of natural cavities were used more frequently than standard nestboxes, but the overall uptake was low. We conclude that nestboxes are an inefficient method of monitoring Marsh Tits, at least in the British context, and researchers should concentrate efforts on locating and monitoring natural nest sites.

    The outcome of the British General Election to be held in just over one week's time is widely regarded as the most difficult in living memory to predict. Current polls suggest that the two main parties are neck and neck but that there will be a landslide to the Scottish Nationalist Party with that party taking most of the constituencies in Scotland. The Liberal Democrats are forecast to loose more than half their seats and the fringe parties of whom the UK Independence Party is the biggest are simply unknown quantities. Much of this volatility relates to long-standing and deeply rooted cultural and nationalist attitudes that relate to geographical fault lines that have been present for 500 years or more but occasionally reveal themselves, at times like this. In this paper our purpose is to raise the notion that these fault lines are critical to thinking about regionalism, nationalism and the hierarchy of cities in Great Britain (excluding Northern Ireland). We use a percolation method (Arcaute et al. 2015) to...

  11. The Planetary Consciousness of British Travel Writers

    Science.gov (United States)

    Henry, H.

    2013-04-01

    Global travel, advanced in the early 20th century by trains, automobiles, and airplanes, transformed modernist thought and experience. Stephen Kern has commented that in the modern period “a series of sweeping changes in technology and culture created distinctive new modes of thinking about and experiencing of time and space. Technological innovations including the telephone, wireless telegraph, x-ray, cinema, bicycle, automobile, and airplane established the material foundation for this reorientation.” (1983, pp. 1-2). Emerging travel technologies not only hurled passengers through multiple time zones in a day but also brought to the fore a global awareness regarding Earth as a globe in space and one's position on it. As early as 1909, while traveling in Florence, Virginia Woolf had noted in her diary, “It is strange how one begins to hold a globe in one's head: I can travel from Florence to Fitzroy Square on solid land all the time” (1984, p. 399). This paper traces the ways modernist British travel writers challenged England's geographical and geopolitical imagination at the turn of the 20th century through their travel narratives.

  12. Climate change and health in British Columbia

    International Nuclear Information System (INIS)

    This document described the models that scientists use to investigate the links between climate change and health. It then reviewed the evidence for possible impacts of climate change on human health. Most models conceptualize that climate change will affect the health of British Columbians directly through physical and biological pathways, and indirectly through complex socio-economic and environmental pathways. The direct physical and biological pathways will be the easiest to investigate, monitor and attribute to climate change, while the indirect socio-economic pathways will be more complex to investigate but will have the most impact. This document also provided guidance for a program of research and policy directions to better predict future impacts of climate change on health in BC and to enhance adaptation to these changes. The document suggested that basic research is needed to develop a made in BC model and infrastructure for climate change and health investigations. Currently, rural and remote forestry-dependent and Aboriginal communities in mountain pine infected zones are particularly vulnerable. However, it was concluded that although there is strong evidence for shifts in climate in BC, no direct evidence exists on the impact of climate change on human health in BC. refs., tabs., figs

  13. British Gas plans global gas unit expansion

    International Nuclear Information System (INIS)

    This paper reports on developing a global gas business, a British Gas plc's strategy for evolving a state owned U.K. gas company to a privatized worldwide oil and gas giant. By 2000, BG's global gas business is expected to provide 20% of its revenues, compared with 40% each from its exploration and production operations and its U.K. gas business. The global gas unit (GGU) plans to meet its targets mainly through acquiring holdings in gas transmission and distribution companies around the world. In the 12 months since GGU was established, it has made two such major acquisitions in this area. BG acquired Consumers Gas Co., Ltd., Ontario, Canada's biggest natural gas distribution company, for $943.5 million. It also took a 10% stake in Catalana de Gas SA, Barcelona, the largest privately owned gas utility in Spain and in terms of number of customers, the fourth largest in western Europe. BG also is targeting additional revenues from developing gas fired cogeneration systems in developing countries with gas reserves but no established transmission and distribution systems

  14. State of the air in British Columbia

    International Nuclear Information System (INIS)

    Scientific evidence is rising regarding the danger of air pollution. Poor air quality can pose a problem in British Columbia, particularly in interior communities when temperature inversions, during certain times of the year, trap pollutants in mountain valleys. This document described where pollutants come from, ambient levels in the atmosphere and how they affect human health. Particular focus was on fine particulate matter, ozone and oxides of nitrogen, as these 3 pollutants have been linked to health impacts. The cost of air pollution through increased health care costs and the economic impact of lost productivity from missed work days was also discussed along with the influence of poor air quality on crop damage and forestry production losses. The document also outlined government and community initiatives to protect public health and listed some measures that individuals can do to keep air clean. Air pollution stems from activities such as land development, burning fossil fuels for energy and transportation, industrial operations, residential wood burning and backyard burning of debris and burning from forestry and agricultural operations. The health impacts range from irritation, to coughing and worsening of existing heart and lung conditions. The document states that despite all measures being taken to reduce emissions and to maintain levels of air pollutants at current low levels, health effects are still observed and still pose a burden to health care cost. Scientific evidence indicates that a further reduction in air pollution will result in health benefits. refs., figs

  15. Appendix XXIX: Succession management in British energy

    International Nuclear Information System (INIS)

    British Energy has formal succession management arrangements, which have evolved over the years to meet the needs of the company. Whilst they are an ongoing process, the arrangements are most manifest in an annual review which results in an overall succession plan for the company. The process embodies a twin-track approach of reviewing existing managers whilst also identifying younger staff with significant potential. These younger staff members are allocated into one of two groupings: those identified as having director level potential, who have their development managed centrally, and those considered to have management potential, the development of whom is managed by the business unit to which they belong, with support from the center as requested. The staff members in both these groupings are kept under review and, if the circumstances warrant it, there may be movement between the two groupings. The aim of succession management is to ensure the company has sufficient experienced, qualified and tested staff to provide succession to senior and other key posts

A checklist of individual duties was provided, with details of responsibilities, safety issues and general instructions for all team members. tabs., figs

  17. British Columbia's new coalbed methane royalty regime

    International Nuclear Information System (INIS)

    The British Columbia Ministry of Energy and Mines is promoting the development of the coalbed methane (CBM) industry in the province in order to make CBM a viable and competitive investment option for industry. It is establishing a regulatory and fiscal regime for CBM development. Issues of concern regarding CBM development include water production, gas production rates, well numbers, and marginal economics. The features of the CBM royalty regime include a new producer cost of service allowance, the creation of a CBM royalty tax bank to collect excess PCOS allowances, and a royalty tax credit for wells drilled by the end of February, 2004. The marginal well adjustment factor threshold has been raised from 180 mcf per day to 600 mcf per day for CBM only. It was noted that royalties will probably not be payable for several years following the first commercial well because royalties are very depending on capital and operating costs, local infrastructure and price. Royalty regimes cannot save CBM from low gas prices, poor resources or economics. 2 figs

    Full Text Available The essence of the British military and security formula in Palestine was the smooth establishment of the Jewish national home with minimum costs of lives and money. However, this British pro-Zionist policy created a continuous security problem, and opened the door to all possibilities of Palestinian revolts and uprisings of both national and religious nature. The British were very active in disarming the Arabs and adopted stringent measures to crush their uprisings and revolts. But, they turned a blind eye to the Jewish arms smuggling and Jewish military organizations, especially, the Hagana, which later became the backbone of the Israeli Army. During Palestinian uprisings of 1920, 1921 and 1929 against the Zionists, most of the Palestinian casualties were inflicted by the British forces despite the fact that the Palestinians avoided attacking the British. The British-Zionist cooperation reached its peak during the Palestinian revolt of 1936-1939, and took different forms, including allowing the Jews to establish a military force of twenty two thousand men under the pretext of protecting the Jewish community.

    Full Text Available The issues of British national identity and social cohesion have become pressing concerns within the multicultural fabric of contemporary British society. The increasing number of immigrants and their offspring, along with the maintenance of their cultural roots, seem to represent a serious defiance to social cohesion and the alleged “purity” of Britishness. A number of race related reports were produced by the official authorities to churn out the necessary steps to be followed by the British (immigrants and host community in order to keep social stability and community cohesion. Thus, the politics of community cohesion came to the fore as the neologism of contemporary British political discourse. Such new discourse of governance has been digested and processed differently by different mass media. It has been decoded, for instance, preferably by mainstream news agencies like BBC News Online. However, arguably, it is read appositionally or at best negotiatedly by ethnicity-related news agencies such as Muslim News Online. In this article, attempt has been made to adopt media discourse analysis tools to decipher the ways Muslim News Online decoded and then encoded the hegemonic official discourses of Britishness and community cohesion. A critical and interpretative approach is used to accomplish such study. The corpus of this study is primarily extracted from the website of the Muslim News Online.

  20. The outlook for the natural gas industry in British Columbia

    International Nuclear Information System (INIS)

    During most of the 1980s, the natural gas industry in British Columbia languished. In 1980, a total of 218 natural gas wells were drilled in the portion of the Western Canadian Sedimentary Basin lying in northeastern British Columbia. By 1983, this number had fallen to only 19. In fact, the average number of gas wells drilled in British Columbia in the nine years following 1980 was only 48 per year. Yearly production during most of the 1980s was also far below levels seen in the previous decade. The outlook for the British Columbia natural gas industry was developed making use of the analytical framework provided in the North American Regional Gas (NARG) model. Using the NARG model enables one to investigate flows of British Columbia natural gas to various markets as a component of the overall North American natural gas market. This paper reviews the appropriate background necessary to familiarize the reader with the natural gas industry in British Columbia and, following a brief description of the NARG model, provides preliminary results from the current research effort

    The study of volcanic rocks and igneous centres has long been a classic part of geological research. Despite the lack of active volcanism, the British Isles have been a key centre for the study of igneous rocks ever since ancient lava flows and excavated igneous centres were recognized there in the 18th century (Hutton, 1788). This led to some of the earliest detailed studies of petrology. The starting point for many of these studies was the British Palaeogene Igneous Province (BPIP; formerly...

  2. Coal and nuclear electricity fuels

    International Nuclear Information System (INIS)

    Comparative economic analysis is used to contrast the economic advantages of nuclear and coal-fired electric generating stations for Canadian regions. A simplified cash flow method is used with present value techniques to yield a single levelized total unit energy cost over the lifetime of a generating station. Sensitivity analysis illustrates the effects of significant changes in some of the cost data. The analysis indicates that in Quebec, Ontario, Manitoba and British Columbia nuclear energy is less costly than coal for electric power generation. In the base case scenario the nuclear advantage is 24 percent in Quebec, 29 percent in Ontario, 34 percent in Manitoba, and 16 percent in British Columbia. Total unit energy cost is sensitive to variations in both capital and fuel costs for both nuclear and coal-fuelled power stations, but are not very sensitive to operating and maintenance costs

  3. Nuclear waste - perception and reality

    International Nuclear Information System (INIS)

    The author addresses the perceptual gap between the general public's attitude to nuclear waste disposal and British Nuclear Fuel Limited's (BNFL) effort to convey the measures actually being taken and the scale of the problem. It is a matter of real concern to BNFL that as much as 80% of the British population believe there is no safe way to dispose of nuclear waste. By comparing the volumes of low-intermediate -and high-level radioactive wastes produced annually to those for industrial waste in general, the nuclear waste issue is shown to represent only a very small fraction of the national toxic waste issue. The building of specific plants for high-and low-level waste disposal is described as is a public relations programme undertaken in 1990 to improve awareness and factual information available about BNFL's commitment to safe waste disposal. The campaign targeted the West Cumbrian region and BNFL employees and has proved successful. U.K

    International Nuclear Information System (INIS)

    The report presents the results of the environmental monitoring programme carried out during 1986 by staff of the Directorate of Fisheries Research, Lowestoft, United Kingdom. The programme was set up to verify the satisfactory control of liquid radioactive waste discharges to the aquatic environment, and to ensure that the resulting public radiation exposure is within nationally-accepted limits. The environmental programme includes monitoring the environmental consequences of discharges of liquid radioactive wastes from four British Nuclear Fuels plc sites - at Sellafield, Springfield, Capenhurst and Chapelcross, and monitoring the environment impact of liquid radioactive discharges from Winfrith and Dounraey. Monitoring is also carried out near nuclear power stations operated by the electricity boards, near Naval establishments, near Amersham International plc, and the marine environment of the Channel Islands States. Results are also presented on the monitoring of the freshwater environment for radioactivity from the Chernobyl reactor accident. (U.K.)

  5. The history of British gynaecological pathology.

    Young, Robert H

    2009-01-01

    The venerable tradition of British gynaecological pathology is honoured by brief comments on those who have pioneered work in this arena, using as the starting point the remarkable Scottish physician Dr Matthew Baillie who, with his uncles, the legendary William and John Hunter, can arguably be considered the founders of medicine in Great Britain. The impact of Baillie's great work 'The Morbid Anatomy of Some of the Most Important Parts of the Human Body' is noted. Because of the fame they achieved in working in other areas, the contributions to gynaecological pathology of Thomas Hodgkin and Richard Bright, particularly the former, are often overlooked and are noted herein as is a remarkable book on the ovary by Charles G. Ritchie, published in 1865. The middle years of the 19th century were notable because of the activities of pioneering surgeons such as Sir Spencer Wells and Lawson Tait which gradually led to a greater emphasis on pathologic examination of specimens removed at operation, as opposed to autopsy evaluation. The closing years of the 19th century and early years of the 20th century were dominated by five individuals, Alban Doran, John Bland-Sutton, Cuthbert Lockyer, Elizabeth Hurdon and John Hammond Teacher. Doran wrote an early study of tubal carcinoma and a book on that organ and the ovary. Bland-Sutton was a remarkably influential surgeon with a significant interest in pathology and also contributed a book on the ovary and fallopian tube as well as one of the early good papers on metastatic tumours to the ovary. Lockyer wrote an outstanding book on uterine fibroids and established, and funded, a museum at Charing Cross Hospital. Hurdon can be considered the first female gynaecological pathologist. She spent much of her active career in the United States working at Johns Hopkins Hospital. She co-authored a monumental book on the appendix, likely never to be equalled. Teacher worked in Glasgow for many years and was almost single-handedly responsible

    The main responsibility of the British Columbia Utilities Commission is to regulate energy utilities under its jurisdiction to ensure that energy rates are fair and that utility operators in the province provide safe, adequate and secure service to their customers. The Commission also approves the construction of new facilities planned by utilities. It also participates in the review of utility and energy projects under the Environmental Assessment Act. Several successes were achieved in 2001 as the utility implemented its first performance plan. Oral public hearings were held for applications by Pacific Northern Gas and by Pembina Pipelines, owners of the common carrier oil pipeline from Taylor to Kamloops. A review of BC Gas' rate design to apportion utility revenue requirements fairly to different classes of customers was successfully achieved by a negotiated settlement process. In 2001, there was also a high level of proposed mergers, acquisitions and divestitures. Duke Energy Corporation's share acquisition of Westcoast Energy's two affiliated gas utilities was approved. BC Gas' application to divest its customer care activities to a joint venture company with Enbridge was also reviewed, and an oral hearing was held to review a West Kootenay Power application to sell its Kootenay River hydroelectric generation assets to Columbia Basin Trust and the Columbia Power Corp. In this case, the decision rendered was that the sale terms had to be changed so that customers could share the proceeds. The utility therefore, decided not to proceed with the sale under these conditions. The BC Hydro legislated rate freeze, which was due to expire on September 30, 2001, was extended for an additional 18 months to allow the new provincial government time to implement a new energy policy.

  8. Norwegian supply of goods and services to the British offshore sector

    International Nuclear Information System (INIS)

    Representatives from ten Norwegian companies in the offshore supplies industry were interviewed to explore the opportunities and barriers they had experienced in their effort to enter the British offshore sector. The interviews revealed that there are mainly four reasons why British sector is regarded as a favorable market: British sector is a natural homemarket, buyers operate both on the British and the Norwegian sector, the British sector can be a ''door-opener'' to the rest of the English speaking world, and finally the British sector is a market of considerable size. The companies had mainly encountered three types of barriers: British culture/communication problems, heavy competition from British suppliers, and protectionism. The report is concluded by summarizing what we believe are the critical success factors for entering the British sector. Directions for further research are also given

    Rising health care costs above inflation are placing serious strains on the sustainability of the Australian Medicare system in its current structure. The Medicare Benefits Schedule (MBS), which lists rebates payable to patients for private medical services provided on a fee-for-service basis, is the cornerstone of the Australian health care system. Introduced in the 1980s, the MBS has changed little despite major advances in the evidence base for the practice of cardiology. We outline how we believe sensible changes to the MBS listings for four cardiac services--invasive coronary angiography, computed tomography coronary angiography, stress testing and percutaneous coronary intervention--would improve the clinical practice of cardiology and save substantial amounts of taxpayer money.

  10. Staff eye lens and extremity exposure in interventional cardiology: Results of the ORAMED project

    International Nuclear Information System (INIS)

    Within the ORAMED project a coordinated measurement program for occupationally exposed medical staff was performed in different hospitals in Europe. The main objectives of ORAMED were to obtain a set of standardized data on doses for staff in interventional cardiology and radiology and to optimize staff protection. Doses were measured with thermoluminescent dosemeters on the ring finger and wrist of both hands, on legs and at the level of the eyes of the main operator performing interventional procedures. In this paper an overview of the doses per procedure measured during 646 interventional cardiology procedures is given for cardiac angiographies and angioplasties (CA/PTCA), radiofrequency ablations (RFA) and pacemaker and defibrillator implantations (PM/ICD). 31% of the monitored procedures were associated with no collective protective equipment, whereas 44% involved a ceiling screen and a table curtain. Although associated with the smallest air kerma – area product (KAP), PM/ICD procedures led to the highest doses. As expected, KAP and doses values exhibited a very large variability. The left side of the operator, most frequently the closest to the X-ray scattering region, was more exposed than his right side. An analysis of the effect of parameters influencing the doses, namely collective protective equipment, X-ray tube configuration and catheter access route, was performed on the doses normalized to KAP. Ceiling screen and table curtain were observed to reduce normalized doses by atmost a factor 4, much smaller than theoretical attenuation factors typical for such protections, i.e. from 10 to 100. This observation was understood as their inappropriate use by the operators and their non-optimized design. Configurations with tube above the patient led to higher normalized doses to the operator than tube below, but the effect of using a biplane X-ray suite was more complex to analyze. For CA/PTCA procedures, the upper part of the operator’s body received

  11. Occupational doses in interventional cardiology: Experiences in obtaining worldwide data as part of the ISEMIR project

    International Nuclear Information System (INIS)

    The International Atomic Energy Agency (IAEA) initiated in early 2009 the Information System on Occupational Exposure in Medicine, Industry and Research, referred to as the ISEMIR project. The project is specifically aimed at improving occupational radiation protection in those areas of radiation use in medicine, industry and research where non-trivial occupational exposures occur. Interventional Cardiology (IC) was the first such area identified and a working group was formed in February 2009 - the Working Group on Interventional Cardiology (WGIC). One of the first actions of the WGIC was to devise questionnaires to gain insight into occupational radiation protection in IC around the world. This included a questionnaire addressed to national or state radiation protection (RP) regulatory bodies (RBs), asking, inter alia: the numbers of workers with personal dosimetry involved in IC procedures in 2008; values of occupational doses (effective dose) in the national authority's database (or database accessible by the national authority); and whether the RP RB defines the number and position of dosimeters for staff monitoring in IC. Responses were received from 81 RBs (56 national RBs and 25 state RBs) out of 191 attempted contacts. About half the RBs (41 out of 81) stated that they were not able to provide occupational dose data for IC, citing reasons that included: no central dose register in the country or state; no easy access to the central dose register by the RB; the RB only had records of doses if they exceed some particular threshold (e.g. investigation or action level); no specific classification for interventional cardiologists, or other persons in IC in the database. The other RBs (40 out of 81) were able to provide some occupational dose data, ranging from detailed dose values to data that were inconsistent and/or ambiguous. Some of the dose data supplied were not suitable for further analysis for reasons that included: reported dose data were

    During the week of 6-12 October 2003 the IAEA organized a Research Coordination Meeting on 'Relationship between lower Respiratory Tract Infection, Gastroesophageal reflux and bronchial Asthma in children' at Hospital San Ignacio in Bogota. Besides there were four workshops in Bogota; workshops on Bone infection and Bone scan in Pediatric ortopaedics at Hospital Militar and Fundacion CardioInfantil, a workshop for Nuclear Medicine Technologists and a workshop on Sentinel Lymph Node mapping and Surgical Gamma Probe Application at Institute of Oncology. A nuclear cardiology workshop was organized in Medellin, and finally crowning them all was the 9th Congress of the Colombian Association of Nuclear Medicine at Cali from 10-12 October, 2003; probably the largest and best Colombian nuclear medicine congress every held in the country. A workshop was also organized in Cali for nuclear medicine technologists in conjunction with the Annual Convention. It was a mix of IAEA's Technical Cooperation and Regular Budget activities along with the activities of Colombian Association of Nuclear Medicine, bringing in absolute synergy to galvanize the entire nuclear medicine community of the country. The week saw nuclear medicine scientists from more than 20 IAEA Member States converging on Colombia to spread the message of nuclear medicine, share knowledge and to foster International understanding and friendship among the nuclear medicine people of the world

This study investigates the impact of different educational activities on students' academic performance in a problem-based learning curriculum. Methods: This is a retrospective cohort study conducted on the cardiology block at the College of Medicine, King Saud Bin Abdulaziz University for Health Sciences, Riyadh, Saudi Arabia. All students who undertook the cardiology block during the academic year 2011–2012 were included. The students' attendance was measured using their overall attendance percentage. This percentage is a product of their attendance of many activities throughout the block. The students' performance was assessed by the final mark obtained, which is a product of many assessment elements. Statistical correlation between students' attendance and performance was established. Results: A total of 127 students were included. The average lecture attendance rate for the medical students in this study was found to be 86%. A significant positive correlation was noted between the overall attendance and the accumulated students' block mark (r=0.52; P<0.001. Students' attendance to different education activities was correlated to their final mark. Lecture attendance was the most significant predictor (P<0.001, that is, 1.0% increase in lecture attendance has predicted a 0.27 increase in students' final block mark. Conclusion: Class attendance has a positive effect on students' academic performance with stronger effect for lecture attendance compared to

    Full Text Available [english] Background: The rapid progress of psychosomatic research in cardiology and also the increasing impact of psychosocial issues in the clinical daily routine have prompted the Clinical Commission of the German Heart Society (DGK to agree to an update of the first state of the art paper on this issue which was originally released in 2008.Methods: The circle of experts was increased, general aspects were implemented and the state of the art was updated. Particular emphasis was dedicated to coronary heart diseases (CHD, heart rhythm diseases and heart failure because to date the evidence-based clinical knowledge is most advanced in these particular areas. Differences between men and women and over the life span were considered in the recommendations as were influences of cognitive capability and the interactive and synergistic impact of classical somatic risk factors on the affective comorbidity in heart disease patients.Results: A IA recommendation (recommendation grade I and evidence grade A was given for the need to consider psychosocial risk factors in the estimation of coronary risks as etiological and prognostic risk factors. Furthermore, for the recommendation to routinely integrate psychosocial patient management into the care of heart surgery patients because in these patients, comorbid affective disorders (e.g. depression, anxiety and post-traumatic stress disorder are highly prevalent and often have a malignant prognosis. A IB recommendation was given for the treatment of psychosocial risk factors aiming to prevent the onset of CHD, particularly if the psychosocial risk factor is harmful in itself (e.g. depression or constrains the treatment of the somatic risk factors. Patients with acute and chronic CHD should be offered anti-depressive medication if these patients suffer from medium to severe states of depression and in this case medication with selective reuptake inhibitors should be given.

  17. Europe's nuclear superpowers

    International Nuclear Information System (INIS)

    Both Great Britain and France are on the verge of nuclear buildups ambitious enough to turn either one into the world's third nuclear superpower. The authors note that the expansion of British and French arsenals will add greatly to the West's nuclear firepower, but on balance these forces will actually weaken Western security. The reason is that they will be deployed largely in potentially vulnerable and destabilizing modes. In addition, they will threaten the unity of the North Atlantic Treaty Organization (NATO) and the viability of the alliance's nuclear doctrine. Perhaps most important, these forces will almost certainly spark a counterbuild-up by the Soviets and fatally complicate the task of arms control. The authors feel, therefore, that the time to include British and French forces in nuclear arms talks is now - before the planned increase in their nuclear might takes place. London and Paris have authorized programs that can give them unprecedented influence with the superpowers and should use this opportunity to slow the arms race, not supercharge it

    Recently a number of new and/or updated sources for estimates of vertical land movements for the British Isles have become available allowing the relative and average changes in sea levels for this region to be revisited. The geodetic data set stems from a combination of re-processed continuous Global Positioning System (GPS) measurements from stations in the British Isles and from a global reference frame network, and absolute gravity (AG) measurements from two stations in the British Isles. The geologic data set of late Holocene sea level indicators has recently been updated, now applying corrections for the 20th century sea level rise, syphoning effect and late Holocene global ice melt, and expanded to Northern Ireland and Ireland. Several new model predictions of the glacial isostatic adjustment (GIA) process active in this region form the modelling data set of vertical land movements for the British Isles. Correcting the updated revised local reference (RLR) trends from the Permanent Service for Mean Sea Level (PSMSL) with these vertical land movement data sets, regional and averaged changes in sea levels around the British Isles have been investigated. Special focus is thereby also given to the coastal areas that have recently been identified within the UK Climate Projections 2009.

    2010-01-01

    Background Subjective parameters such as quality of life or patient satisfaction gain importance as outcome parameters and benchmarks in health care. In many countries hospitals are now undergoing accreditation as mandatory or voluntary measures. It is believed but unproven that accreditations positively influence quality of care and patient satisfaction. The present study aims to assess in a defined specialty (cardiology) the relationship between patient satisfaction (as measured by the recommendation rate) and accreditation status. Methods Consecutive patients discharged from 25 cardiology units received a validated patient satisfaction questionnaire. Data from 3,037 patients (response rate > 55%) became available for analysis. Recommendation rate was used as primary endpoint. Different control variables such as staffing level were considered. Results The 15 accredited units did not differ significantly from the 10 non-accredited units regarding main hospital (i.e. staffing levels, no. of beds) and patient (age, gender) characteristics. The primary endpoint "recommendation rate of a given hospital" for accredited hospitals (65.6%, 95% Confidence Interval (CI) 63.4 - 67.8%) and hospitals without accreditation (65.8%, 95% CI 63.1 - 68.5%) was not significantly different. Conclusion Our results support the notion that - at least in the field of cardiology - successful accreditation is not linked with measurable better quality of care as perceived by the patient and reflected by the recommendation rate of a given institution. Hospital accreditation may represent a step towards quality management, but does not seem to improve overall patient satisfaction. PMID:20459873

  2. Nuclear medicine in China

    International Nuclear Information System (INIS)

    Since China first applied isotopes to medical research in 1956, over 800 hospitals and research institutions with 4000 staff have taken up nuclear technology. So far, over 120 important biologically active materials have been measured by radioimmunoassay in China, and 44 types of RIA kit have been supplied commercially. More than 50,000 cases of hyperthyroidism have been treated satisfactorily with 131I. Radionuclide imaging of practically all organs and systems of the human body has been performed, and adrenal imaging and nuclear cardiology have become routine clinical practice in several large hospitals. The thyroid iodine uptake test, renogram tracing and cardiac function studies with a cardiac probe are also commonly used in most Chinese hospitals. The active principles of more than 60 medicinal herbs have been labelled with isotopes in order to study the drug metabolism and mechanism of action. Through the use of labelled neurotransmitters or deoxyglucose, RIA, radioreceptor assay and autoradiography, Chinese researchers have made remarkable achievements in the study of the scientific basis of acupuncture analgesia. In 1980 the Chinese Society of Nuclear Medicine was founded, and since 1981 the Chinese Journal of Nuclear Medicine has been published. Although nuclear medicine in China has already made some progress, when compared with advanced countries, much progress is still to be made. It is hoped that international scientific exchange will be strengthened in the future. (author)

  5. Postponement and childlessness - Evidence from two British cohorts

    Directory of Open Access Journals (Sweden)

    2008-11-01

    Full Text Available This paper starts by reviewing existing projections of childlessness among British men and women. Low current fertility implies high eventual childlessness unless the postponement of parenthood is taken into account. Such re-timing of first births appears to be occurring differentially across social groups. Exploiting the disaggregated evidence of two British cohort studies, the 1958 National Child Development Study and the 1970 British Cohort Survey, this paper investigates the extent of postponement across cohorts and projects its impact on eventual levels of childlessness. Men and women are considered separately in our models of a population stratified by educational attainment. We find the most striking postponement occurring among graduate men. Among graduate women, after taking family building intentions into account, we estimate that about a quarter of 1970 born graduate women will remain childless, rather than something nearer 40 per cent as had been conjectured elsewhere.

    The Munro-Adams Love Attitude Scale was administered to 133 randomly chosen final-year undergraduate White South African and British university students in this examination of their attitudes toward love, courtship, and marriage in relation to the observation that, although South African tertiary educational institutions exist within the authoritarian and restrictive culture of apartheid, they nevertheless are modeled on the British educational system, which has its roots deeply embedded within a politically democratic context. Results indicated that the South African sample's endorsement of the love attitude items was weaker, except for those pertaining to the power of love, than that of their British counterparts. In addition, the South African scores were lower than those previously reported in other similar cross-cultural research, and there was a differential ranking of the three love styles by the male and female subjects.

    Full Text Available Flat panel detector (FPD technology in interventional cardiology is on the increase due to its varied advantages compared to the conventional image intensifier (II systems. It is not clear whether FPD imparts lower radiation doses compared to II systems though a few studies support this finding. This study intends to compare radiation doses from II and FPD systems for coronaryangiography (CAG and Percutaneous Transluminal Coronary Angioplasty (PTCA performed in a tertiary referral center. Radiation doses were measured using dose area product (DAP meter from patients who underwent CAG (n = 222 and PTCA (n = 75 performed using FPD angiography system. The DAP values from FPD were compared with earlier reported data using II systems from the same referral center where the study was conducted. The mean DAP values from FPD system for CAG and PTCA were 24.35 and 63.64 Gycm 2 and those from II system were 27.71 and 65.44 Gycm 2 . Transition from II to FPD system requires stringent dose optimization strategies right from the initial period of installation.

  8. Multiple procedures and cumulative individual radiation exposure in interventional cardiology: A long-term retrospective study

    International Nuclear Information System (INIS)

    Various studies address discrepancies between guideline recommendations for coronary angiographies and clinical practice. While the issue of the appropriateness of recurrent angiographies was studied focusing on the role of the cardiologist, little is known about individual patients' histories and the associated radiation exposures. We analyzed all patients with coronary artery disease (CAD) in an academic teaching practice who underwent at least one angiography with or without intervention between 2004 and 2009. All performed angiographies in these patients were analyzed and rated by three physicians for appropriateness levels according to cardiology guidelines. Typical exposure data from the medical literature were used to estimate individual radiation exposure. In the cohort of 147 patients, a total of 441 procedures were analyzed: between 1981 and 2009, three procedures were performed per patient (range 1-19) on average. Appropriateness ratings were 'high/intermediate' in 71 %, 'low/no' in 27.6 % and data were insufficient for ratings in 1.4 %. Procedures with 'low/no' ratings were associated with potentially avoidable exposures of up to 186 mSv for single patients. Using retrospective data, we exemplify the potential benefit of guideline adherence to decrease patients' radiation exposures. (orig.)

  9. A practical method for skin dose estimation in interventional cardiology based on fluorographic DICOM information

    International Nuclear Information System (INIS)

    A practical method for skin dose estimation for interventional cardiology patients has been developed to inform pre-procedure planning and post-procedure patient management. Absorbed dose to the patient skin for certain interventional radiology procedures can exceed thresholds for deterministic skin injury, requiring documentation within the patient notes and appropriate patient follow-up. The primary objective was to reduce uncertainty associated with current methods, particularly surrounding field overlap. This was achieved by considering rectangular field geometry incident on a spherical patient model in a polar coordinate system. The angular size of each field was quantified at surface of the sphere, i.e. the skin surface. Computer-assisted design software enabled the modelling of a sufficient dataset that was subsequently validated with radiochromic film. Modelled overlap was found to agree with overlap measured using film to within 2.2 deg. ± 2.0 deg., showing that the overall error associated with the model was <1 %. Mathematical comparison against exposure data extracted from procedural Digital Imaging and Communication in Medicine files was used to generate a graphical skin dose map, demonstrating the dose distribution over a sphere centred at the interventional reference point. Dosimetric accuracy of the software was measured as between 3.5 and 17 % for different variables. (authors)

  10. Entrance surface air kerma in x-ray systems for paediatric interventional cardiology: a national survey

    International Nuclear Information System (INIS)

    The aims of this work were to report the results of a national survey on entrance surface air kerma (ESAK) values for different phantom thicknesses and operation modes in paediatric interventional cardiology (IC) systems and to compare them with previous values. The national survey also offers suggested investigation levels (ILs) for ESAK in paediatric cardiac procedures. ESAK was measured on phantoms of 4-16 cm thickness of polymethyl methacrylate slabs. For low fluoroscopy mode (FM), ESAK rates ranged from 0.11 to 33.1 mGy min-1 and for high FM from 0.34 to 61.0 mGy min-1. For cine mode, values of ESAK per frame were from 1.9 to 78.2 μGy fr-1. The ILs were suggested as the third quartile of the values measured. This research showed lower ESAK values than in previous research, particularly for ESAK values in cine modes. This work represents a first step towards launching a national programme in paediatric dosimetry for IC procedures. (authors)

    Full Text Available Artificial intelligence has significantly contributed in the evolution of medical informatics and biomedicine, providing a variety of tools available to be exploited, from rule-based expert systems and fuzzy logic to neural networks and genetic algorithms. Moreover, familiarizing people with smartphones and the constantly growing use of medical-related mobile applications enables complete and systematic monitoring of a series of chronic diseases both by health professionals and patients. In this work, we propose an integrated system for monitoring and early notification for patients suffering from heart diseases. CardioSmart365 consists of web applications, smartphone native applications, decision support systems, and web services that allow interaction and communication among end users: cardiologists, patients, and general doctors. The key features of the proposed solution are (a recording and management of patients' measurements of vital signs performed at home on regular basis (blood pressure, blood glucose, oxygen saturation, weight, and height, (b management of patients' EMRs, (c cardiologic patient modules for the most common heart diseases, (d decision support systems based on fuzzy logic, (e integrated message management module for optimal communication between end users and instant notifications, and (f interconnection to Microsoft HealthVault platform. CardioSmart365 contributes to the effort for optimal patient monitoring at home and early response in cases of emergency.

  12. Management of stable angina: A commentary on the European Society of Cardiology guidelines.

    2016-09-01

    In 2013 the European Society of Cardiology (ESC) released new guidelines on the management of stable coronary artery disease. These guidelines update and replace the previous ESC guidelines on the management of stable angina pectoris, issued in 2006. There are several new aspects in the 2013 ESC guidelines compared with the 2006 version. This opinion paper provides an in-depth interpretation of the ESC guidelines with regard to these issues, to help physicians in making evidence-based therapeutic choices in their routine clinical practice. The first new element is the definition of stable coronary artery disease itself, which has now broadened from a 'simple' symptom, angina pectoris, to a more complex disease that can even be asymptomatic. In the first-line setting, the major changes in the new guidelines are the upgrading of calcium channel blockers, the distinction between dihydropyridines and non-dihydropyridine calcium channel blockers, and the presence of important statements regarding the combination of calcium channel blockers with beta-blockers. In the second-line setting, the 2013 ESC guidelines recommend the addition of long-acting nitrates, ivabradine, nicorandil or ranolazine to first-line agents. Trimetazidine may also be considered. However, no clear distinction is made among different second-line drugs, despite different quality of evidence in favour of these agents. For example, the use of ranolazine is supported by strong and recent evidence, while data supporting the use of the traditional agents appear relatively scanty. PMID:27222385

    The purpose of this work is to evaluate radiation doses to the lens of urologists during interventional procedures and to compare them with values measured during interventional radiology, cardiology and vascular surgery. The measurements were carried out in a surgical theatre using a mobile C-arm system and electronic occupational dosimeters (worn over the lead apron). Patient and staff dose measurements were collected in a sample of 34 urology interventions (nephrolithotomies). The same dosimetry system was used in other medical specialties for comparison purposes. Median and 3rd quartile values for urology procedures were: patient doses 30 and 40 Gy cm(2); personal dose equivalent Hp(10) over the apron (μSv/procedure): 393 and 848 (for urologists); 21 and 39 (for nurses). Median values of over apron dose per procedure for urologists resulted 18.7 times higher than those measured for radiologists and cardiologists working with proper protection (using ceiling suspended screens) in catheterisation laboratories, and 4.2 times higher than the values measured for vascular surgeons at the same hospital. Comparison with passive dosimeters worn near the eyes suggests that dosimeters worn over the apron could be a reasonable conservative estimate for ocular doses for interventional urology. Authors recommend that at least the main surgeon uses protective eyewear during interventional urology procedures. PMID:26583458

  14. Clustering of Enterococcus faecalis infections in a cardiology hospital neonatal intensive care unit

    2006-04-01

    Full Text Available Early identification of an outbreak is one of the main advantages of routine epidemiological surveillance. Enterococcus spp. used to be regarded as microorganisms of low pathogenicity, because they are part of the normal microbial flora of the gastrointestinal and genitourinary tract. Recently, they have emerged as important pathogenic agents, sometimes causing infections with high mortality rates. We studied a clustering of primary bloodstream infections caused by Enterococcus faecalis in a cardiology hospital neonatal intensive care unit (NICU. Four cases of primary bloodstream infection by E. faecalis were detected from April 15 to May 13, 2004, during active infection surveillance. The isolates were sensitive to glycopeptides. Some aspects of the management of these patients, including the date of insertion and placement of a central venous catheter, prescription of a specific medication, contiguity of beds, personnel attending the patients, and occurrence of diarrhea were analyzed to look for factors that might affect the spread of the microorganisms. Measures taken to hamper the spread included contact precautions throughout the unit, cleansing and disinfection of equipment and surfaces, bathing children with 2% chlorhexidine-gluconate-containing soap, professional reeducation, and reinforcement of all measures to prevent infections. We suggest that there is a need to re-evaluate preventive infection measures and to review the strategies aimed at decreasing the nosocomial infection rate in the NICU.

  15. Radiological protection optimization derived from radiation induced lesions in interventional cardiology finding

    International Nuclear Information System (INIS)

    Interventional Cardiology is one of the specialties in which patients are submitted to the greatest radiation doses with x ray systems used for diagnostic purposes and then, it is also a specialty of high occupational radiation risk. In the last years, several cases of radiation induced lesions produced on patients derived of new complex interventional procedures have been described. As consequence, different rules for avoiding this kind of incidents have been recommended by International Organisations and regulatory Bodies. Nevertheless it has been devoted relatively few attention to the evaluation of the occupational risks that inevitably are also high in these facilities. In this work, some cases of radioinduced skin lesions produced on patients submitted to cardiac ablation procedures are described. Radiological protection considerations of interest for the regulatory Bodies are made, that permit to minimize the probability of these incidents, in what to the X-rays equipment is referred as well as to the operation procedures and level of radiation protection training of the medical specialists.

  16. Influence of patient thickness and operation modes on occupational and patient radiation doses in interventional cardiology

    International Nuclear Information System (INIS)

    Patient and staff dose values in an interventional cardiology laboratory for different operational modes and several patient thicknesses (from 16 to 28 cm, simulated using polymethylmethacrylate) are presented. When increasing patient thicknesses and depending on fluoroscopy and cine modes, occupational doses can increase >30 times the baseline level. Scatter dose rates at the cardiologist's position with no radiation protective tools ranged from 1 to 14 mSv h-1 for fluoroscopy, and from 10 to 47 mSv h-1 during cine acquisition. Patient entrance surface air kerma rates increased by nearly 3 and staff dose rates by up to 2.6 when fluoroscopy was moved from the low to the high mode, for a typical 20 cm thickness. The respective increase factors were 6 and 4.2 when patient thickness rose from 16 to 28 cm, and by 10 and 8.3, when comparing cine acquisition with the low fluoroscopy mode. The knowledge of typical dose rates for each X-ray system in use in catheterisation laboratories is essential in order to optimise protection of patients and staff. (authors)

  17. Estimation of staff lens doses during interventional procedures. Comparing cardiology, neuroradiology and interventional radiology

    International Nuclear Information System (INIS)

    The purpose of this article is to estimate lens doses using over apron active personal dosemeters in interventional catheterisation laboratories (cardiology IC, neuroradiology IN and radiology IR) and to investigate correlations between occupational lens doses and patient doses. Active electronic personal dosemeters placed over the lead apron were used on a sample of 204 IC procedures, 274 IN and 220 IR (all performed at the same university hospital). Patient dose values (kerma area product) were also recorded to evaluate correlations with occupational doses. Operators used the ceiling-suspended screen in most cases. The median and third quartile values of equivalent dose Hp(10) per procedure measured over the apron for IC, IN and IR resulted, respectively, in 21/67, 19/44 and 24/54 μSv. Patient dose values (median/third quartile) were 75/128, 83/176 and 61/159 Gy cm2, respectively. The median ratios for dosemeters worn over the apron by operators ( protected by the ceiling-suspended screen) and patient doses were 0.36; 0.21 and 0.46 μSv Gy-1 cm-2, respectively. With the conservative approach used (lens doses estimated from the over apron chest dosemeter) we came to the conclusion that more than 800 procedures y-1 and per operator were necessary to reach the new lens dose limit for the three interventional specialties.

  19. Recommendations to reduce extremity and eye lens doses in interventional radiology and cardiology

    International Nuclear Information System (INIS)

    The main aim of the Work Package 1 (WP1) of the ORAMED project, Collaborative Project (2008–2011), supported by the European Commission within its 7th Framework Programme, was to obtain a set of standardized data on extremity and eye lens doses for staff in interventional radiology and cardiology (IR/IC) workplaces and to recommend a series of guidelines on radiation protection in order to both guarantee and optimize staff protection. Within the project, coordinated measurements were performed in 34 hospitals in 6 European countries. Furthermore, simulations of the most representative workplaces in IR and IC were performed to determine the main parameters that influence the extremity and eye lens doses. The work presented in this paper shows the recommendations that were formulated by the results obtained from both measurements and simulations. The presented guidelines are directed to operators, assistant personnel, radiation protection officers and medical physics experts. They concern radiation protection issues, such as the use of room protective equipment, as well as the positioning of the extremity and eye lens dosemeters for routine monitoring.

    2013-01-01

    Full Text Available The study presents evaluation of the influence of strain in drawing process and of surface modification on resistance to electrochemical corrosion of wires made of stainless steel for production of guide wires used in invasive cardiology. The results of static tensile test enabled us to determine the course of flow curve of wires made of X10CrNi 18-8 steel as well as mathematical form of flow stress function. Resistance to electrochemical corrosion was evaluated on the ground of registered anodic polarisation curves by means of potentiodynamic method. The tests were performed in solution simulating human blood on samples that were electrolytically polished and samples that were polished and then chemically passivated. Exemplary anodic polarisation curves were given. It was proved that with the applied strain, corrosion properties decrease. It was found that chemical passivation improves wire corrosion characteristics. Statistical analysis showed that there is a significant dependence between corrosion properties (polarisation resistance Rp and strain ε applied in drawing process. Functions that present the change Rp=f(ε were selected. The issue is of importance to guide wire manufacturers because application of the suggested methodology will enable us to forecast corrosion characteristics of wire with the required strength drawn with the applied strain.

  1. Eye dosimetry in interventional radiology and cardiology: current challenges and practical considerations.

    Ciraj-Bjelac, O; Rehani, M M

    2014-12-01

    Interventional radiology and cardiology are areas with high potential for risk to eye lens. Accurate assessment of eye dose is one of the most important aspects of correlating doses with observed lens opacities among workers in interventional suites and ascertaining compliance with regulatory limits. The purpose of this paper is to review current approaches and opportunities in eye dosimetry and assess challenges in particular in accuracy and practicality. The possible approaches include practical dosimetry using passive dosemeters or active dosemeters with obvious advantage of active dosimetry. When neither of these is available, other approaches are based on either retrospective dose assessment using scatter radiation dose levels or correlations between patient dose indices and eye doses to the operators. In spite of all uncertainties and variations, estimation of eye dose from patient dose can be accepted as a compromise. Future challenges include development of practical methods for regular monitoring of individual eye doses and development of better techniques to estimate eye dose from measurements at some reference points.

    Full Text Available Medical imaging has changed to a great extent over the past few decades. It has been revolutionized by three-dimensional (3D imaging techniques. Despite much of modern medicine relying on 3D imaging, which can be obtained accurately, we keep on being limited by visualization of the 3D content on two-dimensional flat screens. 3D-printing of graspable models could become a feasible technique to overcome this gap. Therefore, we printed pre- and postoperative 3D-models of a complex congenital heart defect. With this example, we intend to illustrate that these models hold value in preoperative planning, postoperative evaluation of a complex procedure, communication with the patient, and education of trainees. At this moment, 3D printing only leaves a small footprint, but makes already a big impression in the domain of cardiology and cardiovascular surgery. Further studies including more patients and more validated applications are needed to streamline 3D printing in the clinical setting of daily practice.

    Background Cardiac defects can be the presenting symptom in patients with mutations in the X-linked gene FLNA. Dysfunction of this gene is associated with cardiac abnormalities, especially in the left ventricular outflow tract, but can also cause a congenital malformation of the cerebral cortex. We noticed that some patients diagnosed at the neurogenetics clinic had first presented to a cardiologist, suggesting that earlier recognition may be possible if the diagnosis is suspected. Methods and results From the Erasmus MC cerebral malformations database 24 patients were identified with cerebral bilateral periventricular nodular heterotopia (PNH) without other cerebral cortical malformations. In six of these patients, a pathogenic mutation in FLNA was present. In five a cardiac defect was also found in the outflow tract. Four had presented to a cardiologist before the cerebral abnormalities were diagnosed. Conclusions The cardiological phenotype typically consists of aortic or mitral regurgitation, coarctation of the aorta or other left-sided cardiac malformations. Most patients in this category will not have a FLNA mutation, but the presence of neurological complaints, hyperlaxity of the skin or joints and/or a family history with similar cardiac or neurological problems in a possibly X-linked pattern may alert the clinician to the possibility of a FLNA mutation.

    This study explored nurses' confidence and competence in preparing patients for having an implantable cardioverter defibrillator implanted and for life at home after discharge. Whilst research has identified various physical and psychosocial effects to patients and their partners associated with device implant and subsequent lifestyle adjustments, no research has explored nurses' knowledge of the device or these effects. A survey was designed using a purposive sample of 152 nurses from cardiology areas in four large teaching hospitals and a 28-point postal questionnaire to explore knowledge of the device and its impact. Most subjects were not confident in their abilities to prepare patients for implant or life at home after implant. Knowledge of the device and its effects appeared poorly understood by all nurses, irrespective of additional qualifications, length of time since qualifying or area of work. Many participants were aware of the poor knowledge level of nurses and identified it as a weakness in current care practices. Lack of understanding may impair preparation of patients for implantation of or for living with an implantable cardioverter defibrillator, and feasible strategies to change this situation will require careful consideration and further investment.

    The Melbourne Interventional Group (MIG) is a voluntary collaborative venture of interventional cardiologists practicing at 12 major public and private hospitals in Victoria, designed to record data pertaining to percutaneous coronary interventions (PCI) and perform long-term follow-up. The potential advantages of collaboration involve large-scale analysis of current interventional strategies (e.g. drug-eluting stents, evaluation of new technologies and cost-effective analysis), provide a basis for multi-centred clinical trials and allow comparison of clinical outcomes with cardiac surgery. The established registry documents demographic, clinical and procedural characteristics of consecutive patients undergoing PCI and permits analysis of those characteristics at 30 days and 12 months. The registry is co-ordinated by the Centre of Clinical Research Excellence (CCRE), a research body within the Department of Epidemiology and Preventive Medicine (Monash University, Melbourne). The eventual goal of MIG is to provide a contemporary appraisal of Australian interventional cardiology practice, with opportunities to improve in-hospital and long-term outcomes of patients with coronary artery disease.

    Full Text Available For hospitals’ admission management, the ability to predict length of stay (LOS as early as in the preadmission stage might be helpful to monitor the quality of inpatient care. This study is to develop artificial neural network (ANN models to predict LOS for inpatients with one of the three primary diagnoses: coronary atherosclerosis (CAS, heart failure (HF, and acute myocardial infarction (AMI in a cardiovascular unit in a Christian hospital in Taipei, Taiwan. A total of 2,377 cardiology patients discharged between October 1, 2010, and December 31, 2011, were analyzed. Using ANN or linear regression model was able to predict correctly for 88.07% to 89.95% CAS patients at the predischarge stage and for 88.31% to 91.53% at the preadmission stage. For AMI or HF patients, the accuracy ranged from 64.12% to 66.78% at the predischarge stage and 63.69% to 67.47% at the preadmission stage when a tolerance of 2 days was allowed.

  8. Overcoming a perfect storm: an academic cardiology section's story of survival.

    Increasingly, academic institutions are grappling with financial pressures that threaten the academic mission. The author presents an actual case history in which a section of cardiology in an academic health center was confronted with huge projected deficits that had to be eliminated within the fiscal year. The section used eight principles to shift from deficit to profitability (i.e., having revenue exceed costs). These principles included confronting the brutal facts, managing costs and revenue cycles, setting expectations for faculty, and quality improvement. The section accomplished deficit reduction through reducing faculty salaries (nearly $2 million) and nonfaculty salaries ($1.3 million) and reducing operational costs while maintaining revenues by increasing individual faculty productivity and reducing accounts receivable. In the face of these reductions, clinical revenues were maintained, but research revenue and productivity fell (but research is being fostered now that clinical services are profitable again). These principles can be used to stabilize the financial position of clinical practices in academic settings that are facing financial challenges. PMID:17327712

    Improved therapy and prophylaxis of cardiovascular diseases have contributed to an increase in life expectancy like no other field of medicine. However, many cardiological diseases remain untreatable and standard therapies often work only in a minority of patients or cause more harm than benefit. Personalized approaches appear to be a promising solution. Monogenic heart diseases are paradigmatic for this approach and can in rare cases be treated mutation specifically. Overall, however, success remains limited. Next generation sequencing will facilitate the identification of mutations causing diseases. Cell culture models based on induced pluripotent stem cells open the perspective of individualized testing of disease severity and pharmacological or genetic therapy. In contrast to monogenic diseases genetic testing plays no practical role yet in the management of multifactorial cardiovascular diseases. Biomarkers can identify individuals with increased cardiovascular risk. Furthermore, biomarker-guided therapy represents an attractive option with troponin-guided therapy of acute coronary syndromes as a successful example. Individual responses to drugs vary and are partly determined by genes. Simple genetic analyses can improve response prediction and minimize side effects in cases such as warfarin and high doses of simvastatin. Taken together personalized approaches will gain importance in the cardiovascular field but this requires the development of better methods and research that quantifies the true value of the new knowledge.

    A practical method for skin dose estimation for interventional cardiology patients has been developed to inform pre-procedure planning and post-procedure patient management. Absorbed dose to the patient skin for certain interventional radiology procedures can exceed thresholds for deterministic skin injury, requiring documentation within the patient notes and appropriate patient follow-up. The primary objective was to reduce uncertainty associated with current methods, particularly surrounding field overlap. This was achieved by considering rectangular field geometry incident on a spherical patient model in a polar coordinate system. The angular size of each field was quantified at surface of the sphere, i.e. the skin surface. Computer-assisted design software enabled the modelling of a sufficient dataset that was subsequently validated with radiochromic film. Modelled overlap was found to agree with overlap measured using film to within 2.2° ± 2.0°, showing that the overall error associated with the model was < 1 %. Mathematical comparison against exposure data extracted from procedural Digital Imaging and Communication in Medicine files was used to generate a graphical skin dose map, demonstrating the dose distribution over a sphere centred at the interventional reference point. Dosimetric accuracy of the software was measured as between 3.5 and 17 % for different variables. PMID:25994848

  11. Use of active personal dosemeters in interventional radiology and cardiology: Tests in hospitals – ORAMED project

    International Nuclear Information System (INIS)

    Although active personal dosemeters (APDs) are not used quite often in hospital environments, the possibility to assess the dose and/or dose rate in real time is particularly interesting in interventional radiology and cardiology (IR/IC) since operators can receive relatively high doses while standing close to the primary radiation field. A study concerning the optimization of the use of APDs in IR/IC was performed in the framework of the ORAMED project, a Collaborative Project (2008–2011) supported by the European Commission within its 7th Framework Program. This paper reports on tests performed with APDs on phantoms using an X-ray facility in a hospital environment and APDs worn by interventionalists during routine practice in different European hospitals. The behaviour of the APDs is more satisfactory in hospitals than in laboratories with respect to the influence of the tube peak high voltage and pulse width, because the APDs are tested in scattered fields with dose equivalent rates generally lower than 1 Sv.h−1. .

  12. Radiation dose and image quality for paediatric interventional cardiology systems. A national survey in Chile

    International Nuclear Information System (INIS)

    Radiation dose and image quality for paediatric protocols in all five X-ray fluoroscopy systems used for interventional cardiology procedures existing in Chile have been evaluated. Entrance surface air kerma (ESAK) and image quality using a test object (TO) and polymethyl methacrylate (PMMA) phantoms have been measured for the typical paediatric patient thicknesses (4-16 cm of PMMA). Images from fluoroscopy (low (FL), medium and high) and cine (CI) modes have been archived in DICOM format. Signal-to-noise ratio (SNR), figure of merit (FOM) and high-contrast spatial resolution (HCSR) have been computed from the images. The ratio between the maximum and the minimum value of ESAK per frame for a given fluoroscopy mode between the five systems ranges from 2 to 5 and from 14 to 38 for CI mode. SNR, FOM and HCSR showed a great variability for the different acquisition modes (AMs) and PMMA thickness. In the near future, it is urgent to upgrade Chilean legislation on radiation protection to incorporate quality assurance programmes that will allow us to evaluate and optimise the X-ray systems used in medical applications. Increments in doses per frame when increasing phantom thickness and when used CI runs instead of FL runs can be considered by the cardiologist in the good management of patient dose and allow them to select the best imaging AM during clinical procedures.

    A recently introduced health care reform in Italy will modify substantially the scenario in which all physicians and also the cardiac specialists working in and out of the hospitals will operate. Therefore it is important that the cardiological community, who manages a large proportion of human and financial resources of the Italian National Health Service, knows the reform and interacts with the national and local authorities for the best implementation of the basic principles on which the reform has been founded. These principles are the following: the Italian health service will guarantee all citizens the so-called "essential levels of care" identified in accordance with four distinctive features. They must: 1) safeguard real needs of care (i.e. cosmetic surgery is not considered), 2) be evidence based, 3) be appropriate for individual patients, 4) be cost-effective. In a context of scarce resources and rapidly increasing demand of care this basic strategy seems to be the only one suitable for a National Health Service, but the application of this principle in the real world of care seems a very difficult task, and the role of medical associations is obviously crucial for a good outcome. This report illustrates some articles of the law that deal with the medical profession: guidelines and appropriateness of the criteria; accreditation, clinical competence and quality control; continuing medical education.

    The purpose of this article is to estimate lens doses using over apron active personal dosemeters in interventional catheterisation laboratories (cardiology IC, neuroradiology IN and radiology IR) and to investigate correlations between occupational lens doses and patient doses. Active electronic personal dosemeters placed over the lead apron were used on a sample of 204 IC procedures, 274 IN and 220 IR (all performed at the same university hospital). Patient dose values (kerma area product) were also recorded to evaluate correlations with occupational doses. Operators used the ceiling-suspended screen in most cases. The median and third quartile values of equivalent dose Hp(10) per procedure measured over the apron for IC, IN and IR resulted, respectively, in 21/67, 19/44 and 24/54 µSv. Patient dose values (median/third quartile) were 75/128, 83/176 and 61/159 Gy cm(2), respectively. The median ratios for dosemeters worn over the apron by operators (protected by the ceiling-suspended screen) and patient doses were 0.36; 0.21 and 0.46 µSv Gy(-1) cm(-2), respectively. With the conservative approach used (lens doses estimated from the over apron chest dosemeter) we came to the conclusion that more than 800 procedures y(-1) and per operator were necessary to reach the new lens dose limit for the three interventional specialties.

    Full Text Available The objective of this exploratory study was to describe and map out the billing process in a public tertiary-level university hospital specialized in cardiology and pulmonology. In the period between May and June of 2012, we identified and documented the steps in the process validated by the professionals involved in the hospital bill audit service. We found that during billing pre-analysis, auditors make corrections to justify the billing of procedures and to avoid unwarranted billing and loss of revenue. Mapping out the process allowed us to propose strategies to minimize the time for presenting bills to payment sources. By bringing visibility to this process, which is fundamental for the economic-financial balance of the studied hospital, we bring such knowledge to the public domain. Thus, it is accessible to other health organizations that wish to increment their revenue and reduce divergences between patient charts and the patient’s hospital bill. doi: 10.5216/ree.v16i3.23487.

  17. Eye dosimetry in interventional radiology and cardiology: current challenges and practical considerations

    International Nuclear Information System (INIS)

    Interventional radiology and cardiology are areas with high potential for risk to eye lens. Accurate assessment of eye dose is one of the most important aspects of correlating doses with observed lens opacities among workers in interventional suites and ascertaining compliance with regulatory limits. The purpose of this paper is to review current approaches and opportunities in eye dosimetry and assess challenges in particular in accuracy and practicality. The possible approaches include practical dosimetry using passive dosemeters or active dosemeters with obvious advantage of active dosimetry. When neither of these is available, other approaches are based on either retrospective dose assessment using scatter radiation dose levels or correlations between patient dose indices and eye doses to the operators. In spite of all uncertainties and variations, estimation of eye dose from patient dose can be accepted as a compromise. Future challenges include development of practical methods for regular monitoring of individual eye doses and development of better techniques to estimate eye dose from measurements at some reference points.

    Medical imaging has changed to a great extent over the past few decades. It has been revolutionized by three-dimensional (3D) imaging techniques. Despite much of modern medicine relying on 3D imaging, which can be obtained accurately, we keep on being limited by visualization of the 3D content on two-dimensional flat screens. 3D-printing of graspable models could become a feasible technique to overcome this gap. Therefore, we printed pre- and postoperative 3D-models of a complex congenital heart defect. With this example, we intend to illustrate that these models hold value in preoperative planning, postoperative evaluation of a complex procedure, communication with the patient, and education of trainees. At this moment, 3D printing only leaves a small footprint, but makes already a big impression in the domain of cardiology and cardiovascular surgery. Further studies including more patients and more validated applications are needed to streamline 3D printing in the clinical setting of daily practice. PMID:27195174

  19. How Canadians feel about nuclear energy

    International Nuclear Information System (INIS)

    A survey conducted by Decima Research in April 1989 showed that 50% of Canadians were somewhat or strongly in favour of nuclear energy, the percentage varying from 37% in British Columbia to 65% in Ontario. A majority (56%) questioned the nuclear industry's ability to handle its waste safely, but 45% believed that it was working hard to solve the problem. It was evident that an advertising campaign by the Canadian Nuclear Association had an effect

    We believe this is the first-ever attempt to chart the full extent of cycling’s contribution to the British economy. Previous studies have focused on particular sectors such as the bicycle retail trade, but never before has a study been conducted into the true ‘Gross Cycling Product’ (GCP) of UK plc – from bike sales to improved health. The GCP report was conceived by Sky and British Cycling and has been made a reality through the London School of Economics. We commissioned the report, t...
