Sample records for cardiology japanese databases

  1. Japanese efforts to establish international knowledge database

    International Nuclear Information System (INIS)

    A lot of information on Fast Reactor has been published in Japan. Publication was accelerated in these days. Most is maintained in digitalized form on CPU network, with necessary search engine to help users. However in most cases Japanese language is used in source, in catalogue and in search engine. Tremendous efforts have been, and are being, performed to register to INIS, information on nuclear technology published in Japan, by JAEA in collaboration with JST and IMIC. Most of important information on Fast Reactor has already been registered. Review of the registration status, and small amount of addition can improve the content. Action Plans by IAEA/TWGFR are desirable. Registration to the present INIS Atomindex is laborious corresponding to its unique data form. Simplification is desirable with the aid of most recent CPU network technology. JAEA may be called as a good trial. Action Plans by IAEA/TWGFR might be effective

    Whole-genome and -exome resequencing using next-generation sequencers is a powerful approach for identifying genomic variations that are associated with diseases. However, systematic strategies for prioritizing causative variants from many candidates to explain the disease phenotype are still far from being established, because the population-specific frequency spectrum of genetic variation has not been characterized. Here, we have collected exomic genetic variation from 1208 Japanese individuals through a collaborative effort, and aggregated the data into a prevailing catalog. In total, we identified 156 622 previously unreported variants. The allele frequencies for the majority (88.8%) were lower than 0.5% in allele frequency and predicted to be functionally deleterious. In addition, we have constructed a Japanese-specific major allele reference genome by which the number of unique mapping of the short reads in our data has increased 0.045% on average. Our results illustrate the importance of constructing an ethnicity-specific reference genome for identifying rare variants. All the collected data were centralized to a newly developed database to serve as useful resources for exploring pathogenic variations. Public access to the database is available at http://www.genome.med.kyoto-u.ac.jp/SnpDB/. PMID:26911352

    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. World wide web for database of Japanese translation on international nuclear event scale reports

    International Nuclear Information System (INIS)

    The International Nuclear Event Scale (INES) is a means designed for providing prompt, clear and consistent information related to nuclear events, that occurred at nuclear facilities, and facilitating communication between the nuclear community, the media and the public. The INES is jointly operated by the IAEA and the OECD-NEA. Nuclear events reported are rated by the Scale', a consistent safety significance indicator. The scale runs from level 0, for events with no safety significance, to level 7 for a major accident with widespread health and environmental effects. The Japan Atomic Energy Research Institute (JAERI) has been promptly translating the INES reports into Japanese and developing a world-wide-web database for the Japanese translation, aiming at more efficient utilization of the INES information inside Japan. The present paper briefly introduces the definitions of INES rating levels and the scope of the Scale, and describes the outlines of the database (the information stored in the database, its functions and how to use it). As well, technical use of the INES reports and the availability/ effectiveness of the database are discussed. (author)

    Full Text Available The number of Japanese language learners outside Japan, especially of advanced level learners, is increasing yearly. From the intermediate level onwards, they could profit from bilingual Japanese learners’ dictionaries in their native language, but in most linguistic areas of the world only very simple dictionaries for beginners and for tourists are available. Our project therefore aims at supporting the compilation of Japanese language learners’ dictionaries for intermediate and advanced learners by building a database of contents needed when editing a Japanese language learners’ dictionary, and offering it online. This 4 year project is going to be running from 2011 to 2014. Two surveys were conducted: a survey of the vocabulary used in textbooks of Japanese as a foreign language and a quantitative survey on the targeted area of the Japanese language in a large-scale corpus, in order to select the list of words to be included in the database, and a general list of basic vocabulary for Japanese language instruction was created. At present, usage examples are being compiled on the basis of this vocabulary list, and a database system is being developed. A prototype of a database search interface and download system has been completed. The database is going to include various types of information which are considered to be useful for learners, such as grammar, phonetics, synonyms, collocations, stylistics, learners’ errors etc. These are presently being studied in detail to be made public in 2014.-----Število učencev in študentov japonskega jezika zunaj Japonske, posebej na višjih nivojih, narašča iz leta v leto.

  8. 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

    After defining tele-medicine, we describe its situation in the public health service of South Africa and its application to cardiology. Methods of communication relevant to tele-cardiology are outlined, together with their bearing on primary healthcare. The range of tele-cardiological applications to electrocardiology, echocardiology, auscultation, imaging and pathology are indicated. Tele-cardiology's contributions to a range of cardiological problems and types of management are described briefly. Finally, a mention is made of the relevance of tele-medicine to education and the costs related to cardiology, with an indication of some future needs for tele-cardiology. PMID:16547558

  10. 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

  11. 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.)

This has been attributed to several factors, including treatment guidelines recommending prescription of multiple medications and a continuing increase in the elderly population with multiple comorbidities.Objective: This study was aimed at investigating the association between polypharmacy, defined as the concomitant use of five or more medications, and risk of adverse drug reaction (ADR in elderly Japanese hypertensive patients to examine the hypothesis that risk of ADR increases with the administration of an increasing number of co-medications.Methods: Using a retrospective cohort design, the data regarding all hypertensive patients aged 65 years or older were extracted from the Risk/Benefit Assessment of Drugs – Analysis and Response Council antihypertensive medication database. The data were reviewed for classification of patients into one of three groups according to drug use at the initiation of therapy – a monotherapy group composed of patients who had taken the investigated drug only, a co-medication group composed of patients who had taken the investigated drug and a maximum of three other medications, and a polypharmacy group composed of patients who had taken the investigated drug and four or more other medications – and determination of the number of ADR events experienced. Estimated rate ratios (RRs and 95% confidence intervals (CIs were calculated using a Poisson regression model adjusted for drug category and patient age and sex. Various sensitivity analyses were performed to confirm the robustness of the study findings.Results: Of 61,661 elderly

    We analyzed the cases of side effects due to antipsychotics reported to Japan's Pharmaceuticals and Medical Devices Agency (PMDA) from Jan. 2004 to Dec. 2012. We used the Japanese Adverse Drug Event Report Database (JADER) and analyzed 136 of 216,945 cases using the defined terms. We also checked the cardiac adverse effects listed in the package inserts of the antipsychotics involved. We found cases of Ikr blockade resulting in sudden death (49 cases), electrocardiogram QT prolonged (29 cases), torsade de pointes (TdP, 19 cases), ventricular fibrillation (VF, 10 cases). M2 receptor blockade was observed in tachycardia (8 cases) and sinus tachycardia (3 cases). Calmodulin blockade was involved in reported cardiomyopathy (3 cases) and myocarditis (1 case). Multiple adverse events were reported simultaneously in 14 cases. Our search of package inserts revealed warnings regarding electrocardiogram QT prolongation (24 drugs), tachycardia (23), sudden death (18), TdP (14), VF (3), myocarditis (1) and cardiomyopathy (1). We suggest that when an antipsychotic is prescribed, the patient should be monitored regularly with ECG, blood tests, and/or biochemical tests to avoid adverse cardiac effects. PMID:25069255

  15. 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

  16. 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.

  19. 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

However, data variations affect statistical analyses (eg, signal detection. Further, differences in regulations, social issues, and health care systems can cause variations in AE data. The present study examined similarities and differences between two publicly available databases, ie, the Japanese Adverse Drug Event Report (JADER database and the US Food and Drug Administration Adverse Event Reporting System (FAERS, and how they affect signal detection.Methods: Two AE data sources from 2010 were examined, ie, JADER cases (JP and Japanese cases extracted from the FAERS (FAERS-JP. Three methods for signals of disproportionate reporting, ie, the reporting odds ratio, Bayesian confidence propagation neural network, and Gamma Poisson Shrinker (GPS, were used on drug-event combinations for three substances frequently recorded in both systems.Results: The two databases showed similar elements of AE reports, but no option was provided for a shareable case identifier. The average number of AEs per case was 1.6±1.3 (maximum 37 in the JP and 3.3±3.5 (maximum 62 in the FAERS-JP.

    @@ 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.

The aim of this study was to describe the epidemiology of childhood intussusception in Japan using data from a nationwide inpatient database. Methods We screened the database for eligible cases ≤ 18 years of age, who were coded with a discharge diagnosis of intussusception (International Classification of Diseases, 10th revision: K-561 between July to December in 2007 and 2008. We then selected cases according to Level 1 of the diagnostic certainty criteria developed by the Brighton Collaboration Intussusception Working Group. We examined the demographics, management, and outcomes of cases, and estimated the incidence of intussusception. Results We identified 2,427 cases of intussusception. There were an estimated 2,000 cases of infantile intussusception annually in Japan, an incidence of 180-190 cases per 100,000 infants. The median age at diagnosis was 17 months, and two-thirds of the patients were male. Treatment with an enema was successful in 93.0% of cases (2255/2427. The remainder required surgery. Secondary cases accounted for 3.1% (76/2427. Median length of hospital stay was 3 days. Of the 2,427 cases, we found 2 fatal cases associated with intussusception. Conclusions This is currently the largest survey of childhood intussusception in Asia using a standardized case definition. Our results provide an estimate of the baseline risk of intussusception in Japan, and it is higher than the risk observed in other countries.

    The upper atmospheric observational study is the area which an international collaboration is crucially important. The Japanese Inter-university Upper atmosphere Global Observation NETwork project (2009-2014), IUGONET, is an inter-university program by the National Institute of Polar Research (NIPR), Tohoku University, Nagoya University, Kyoto University, and Kyushu University to build a database of metadata for ground-based observations of the upper atmosphere. In order to investigate the mechanism of long-term variations in the upper atmosphere, we need to combine various types of in-situ observations and to accelerate data exchange. The IUGONET institutions have been archiving observed data by radars, magnetometers, photometers, radio telescopes, helioscopes, etc. in various altitude layers from the Earth's surface to the Sun. The IUGONET has been developing systems for searching metadata of these observational data, and the metadata database (MDB) has already been operating since 2011. It adopts DSPACE system for registering metadata, and it uses an extension of the SPASE data model of describing metadata, which is widely used format in the upper atmospheric society including that in USA. The European Union project ESPAS (2011-2015) has the same scientific objects with IUGONET, namely it aims to provide an e-science infrastructure for the retrieval and access to space weather relevant data, information and value added services. It integrates 22 partners in European countries. The ESPAS also plans to adopt SPASE model for defining their metadata, but search system is different. Namely, in spite of the similarity of the data model, basic system ideas and techniques of the system and web portal are different between IUGONET and ESPAS. In order to connect the two systems/databases, we are planning to take an ontological method. The SPASE keyword vocabulary, derived from the SPASE data model shall be used as standard for the description of near-earth and space data

    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.

  9. 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

    Full Text Available Databases are deeply embedded in archaeology, underpinning and supporting many aspects of the subject. However, as well as providing a means for storing, retrieving and modifying data, databases themselves must be a result of a detailed analysis and design process. This article looks at this process, and shows how the characteristics of data models affect the process of database design and implementation. The impact of the Internet on the development of databases is examined, and the article concludes with a discussion of a range of issues associated with the recording and management of archaeological data.

      Safety information regarding drug use during pregnancy is insufficient. The present study aimed to establish an optimal signal detection method to identify adverse drug reactions in pregnant women and to evaluate information in the Japanese Adverse Drug Event Report (JADER) database between April 2004 and November 2014. We identified reports on pregnant women using the Standardised MedDRA Queries. We calculated the proportional reporting ratio (PRR) and reporting odds ratio (ROR) of the risk factors for the two known risks of antithyroid drugs and methimazole (MMI) embryopathy, and ritodrine and fetal/infant cardiovascular events. The PRR and ROR values differed between all reports in the JADER database and those on pregnant women, affecting whether signal detection criteria were met. Therefore we considered that reports on pregnant women should be used when risks associated with pregnancy were determined using signal detection. Analyses of MMI embryopathy revealed MMI signals [PRR, 159.7; ROR, 669.9; 95% confidence interval (CI), 282.4-1588.7] but no propylthiouracil signals (PRR, 1.98; ROR, 2.0; 95%CI, 0.3-15.4). These findings were consistent with those of reported risks. Analyses of fetal/infant cardiovascular events revealed ritodrine signals (PRR, 2.1; ROR, 2.1; 95%CI, 1.4-3.3). These findings were also consistent with reported risks. Mining the JADER database was helpful for analyzing adverse drug reactions in pregnant women. PMID:26935093

    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

  3. Study of fatigue failures to improve safety based on the analyses of failure database in Japanese nuclear power plant

    International Nuclear Information System (INIS)

    After Fukushima-Daiichi accident, nuclear power plants are highly requested to enhance safety against severe accident. It is important to prevent fatigue failure for operating nuclear power plants, especially pressure boundary of components to ensure safety. This paper studies the failure database of nuclear power plant in Japan (NUCIA) and extracts the events caused by fatigue failure. Fatigue failure can be classified according to fatigue mechanism such as mechanical vibration, fluid vibration, high-cycle thermal fatigue, low-cycle fatigue, and fretting fatigue. The study focuses on the classification of significance in safety function of the system, the trend and the countermeasures taken for each kind of fatigue failure. The detailed analysis of fatigue failure in safety-related components proposes important modification of maintenance program and screening criteria of components to be evaluated to ensure safety in system level.

  4. 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.

    Full Text Available Abstract Background Little is known about the effects of professional staffing on cancer surgical outcomes. The present study aimed to investigate the association between cancer surgical outcomes and physician/nurse staffing in relation to hospital volume. Methods We analyzed 131,394 patients undergoing lung lobectomy, esophagectomy, gastrectomy, colorectal surgery, hepatectomy or pancreatectomy for cancer between July and December, 2007–2008, using the Japanese Diagnosis Procedure Combination database linked to the Survey of Medical Institutions data. Physician-to-bed ratio (PBR and nurse-to-bed ratio (NBR were determined for each hospital. Hospital volume was categorized into low, medium and high for each of six cancer surgeries. Failure to rescue (FTR was defined as a proportion of inhospital deaths among those with postoperative complications. Multi-level logistic regression analysis was performed to examine the association between physician/nurse staffing and FTR, adjusting for patient characteristics and hospital volume. Results Overall inhospital mortality was 1.8%, postoperative complication rate was 15.2%, and FTR rate was 11.9%. After adjustment for hospital volume, FTR rate in the group with high PBR (≥19.7 physicians per 100 beds and high NBR (≥77.0 nurses per 100 beds was significantly lower than that in the group with low PBR ( Conclusions Well-staffed hospitals confer a benefit for cancer surgical patients regarding reduced FTR, irrespective of hospital volume. These results suggest that consolidation of surgical centers linked with migration of medical professionals may improve the quality of cancer surgical management.

  13. [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

  14. 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)

    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.

    Hypoglycemia due to treatment with oral anti-hyperglycemic agents (OHAs) is a major clinical problem in patients with type 2 diabetes mellitus. The aim of the present study was to evaluate the risk of hypoglycemia due to OHA use by using the Japanese Adverse Drug Event Report (JADER) database. To this end, reports of hypoglycemia events included in the JADER database between 2004 and 2012 were analyzed by calculating the reporting odds ratio (OR). The Medical Dictionary for Regulatory Activities Preferred Terms was used to identify hypoglycemia; 254392 reports were found in the JADER database, of which 13269 were excluded because the age and sex of the patient were not reported. Finally, 241123 reports were analyzed. Among OHAs, sulfonylureas showed the highest adjusted OR (adjusted OR, 10.13; 95% confidence interval, 9.08-11.26). The adjusted ORs for meglitinides, biguanide, thiazolidinedione, alpha-glucosidase inhibitors, and dipeptidyl peptidase-4 inhibitors were significantly lower than that of sulfonylureas. The adjusted OR of meglitinides (3.17; 95% confidence interval, 2.23-4.36) was significantly higher than that of alpha-glucosidase inhibitors or thiazolidinedione. We observed no difference between the adjusted ORs for biguanide, thiazolidinedione, alpha-glucosidase inhibitors, and dipeptidyl peptidase-4 inhibitors. Data mining of the JADER database was useful for analyzing OHA-associated hypoglycemia events. The results of our study suggested a low risk of hypoglycemia associated with biguanide, thiazolidinedione, alpha-glucosidase inhibitors, and dipeptidyl peptidase-4 inhibitors in clinical practice.

    Full Text Available AbstractBibliometry is a quantitative statistical technique to measure levels of production and dissemination of knowledge, as well as a useful tool to track the development of an scientific area. The valuation of production required for recognition of researchers and magazines is accomplished through tools called bibliometricindexes, divided into quality indicators and scientific impact. Initially developed for monographs of statistical measures especially in libraries, today bibliometrics is mainly used to evaluate productivity of authors and citation repercussion. However, these tools have limitations and sometimes provoke controversies about indiscriminate application, leading to the development of newer indexes. It is important to know the most common search indexes and use it properly even acknowledging its limitations as it has a direct impact in their daily practice, reputation and funds achievement.

  3. 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)

  4. 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

    "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

  8. 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

  9. 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)

    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

  12. 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

    Selective beta-adrenergic drugs are used clinically to treat various diseases. Because of imperfect receptor selectivity, beta-adrenergic drugs cause some adverse drug events by stimulating other adrenergic receptors. To examine the association between selective beta-adrenergic drugs and blood pressure elevation, we reviewed the Japanese Adverse Drug Event Reports (JADERs) submitted to the Japan Pharmaceuticals and Medical Devices Agency. We used the Medical Dictionary for Regulatory Activities (MedDRA) Preferred Terms extracted from Standardized MedDRA queries for hypertension to identify events related to blood pressure elevation. Spontaneous adverse event reports from April 2004 through May 2015 in JADERs, a data mining algorithm, and the reporting odds ratio (ROR) were used for quantitative signal detection, and assessed by the case/non-case method. Safety signals are considered significant if the ROR estimates and lower bound of the 95% confidence interval (CI) exceed 1. A total of 2021 reports were included in this study. Among the nine drugs examined, significant signals were found, based on the 95%CI for salbutamol (ROR: 9.94, 95%CI: 3.09-31.93) and mirabegron (ROR: 7.52, 95%CI: 4.89-11.55). The results of this study indicate that some selective beta-adrenergic drugs are associated with blood pressure elevation. Considering the frequency of their indications, attention should be paid to their use in elderly patients to avoid adverse events. PMID:27374969

  16. 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

  18. 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

  3. 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.)

  4. 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

  5. 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.

    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

    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.

  8. 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)

  9. 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)

    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

  15. 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

  16. 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.

    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

  9. 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

  10. 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

  12. 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

  3. 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.

  4. 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.

      The Japanese Ministry of Health, Labor, and Welfare lists hand-foot syndrome as a serious adverse drug event. Therefore, we evaluated its association with anticancer drug therapy using case reports in the Japanese Adverse Drug Event Report (JADER) and the US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS). In addition, we calculated the reporting odds ratio (ROR) of anticancer drugs potentially associated with hand-foot syndrome, and applied the Weibull shape parameter to time-to-event data from JADER. We found that JADER contained 338224 reports from April 2004 to November 2014, while FAERS contained 5821354 reports from January 2004 to June 2014. In JADER, the RORs [95% confidence interval (CI)] of hand-foot syndrome for capecitabine, tegafur-gimeracil-oteracil, fluorouracil, sorafenib, and regorafenib were 63.60 (95%CI, 56.19-71.99), 1.30 (95%CI, 0.89-1.89), 0.48 (95%CI, 0.30-0.77), 26.10 (95%CI, 22.86-29.80), and 133.27 (95%CI, 112.85-157.39), respectively. Adverse event symptoms of hand-foot syndrome were observed with most anticancer drugs, which carry warnings of the propensity to cause these effects in their drug information literature. The time-to-event analysis using the Weibull shape parameter revealed differences in the time-dependency of the adverse events of each drug. Therefore, anticancer drugs should be used carefully in clinical practice, and patients may require careful monitoring for symptoms of hand-foot syndrome. PMID:26935094

  6. 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. Simulation-based planning of surgical interventions in pediatric cardiology

    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.

  15. 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)

    2010-01-01

    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.

    The purpose of this article is to present the results of connecting the interventional radiology and cardiology laboratories of five university hospitals to a unique server using an automatic patient dose registry system (Dose On Line for Interventional Radiology, DOLIR) developed in-house, and to evaluate its feasibility more than a year after its introduction. The system receives and stores demographic and dosimetric parameters included in the MPPS DICOM objects sent by the modalities to a database. A web service provides a graphical interface to analyse the information received. During 2013, the system processed 10 788 procedures (6874 cardiac, 2906 vascular and 1008 neuro interventional). The percentages of patients requiring clinical follow-up due to potential tissue reactions before and after the use of DOLIR are presented. The system allowed users to verify in real-time, if diagnostic (or interventional) reference levels are fulfilled. (authors)

  5. Teaching Japanese Popular Culture

    Full Text Available Japanese popular culture has arrived on American college campuses as never before. Student interest in Japanese manga (comic books, anime (animated films and television shows, and video games drives much of the enrollment in Japanese courses and Japanese majors and minors. In response to student interest, as well as the establishment of popular culture as a topic of serious academic scholarship, the demand for courses on Japanese popular culture has never been higher. Yet the number of scholars specializing in the study of popular culture is still relatively small. This can potentially create problems, as faculty teach outside their expertise, and perhaps face an uncomfortable situation in which the students know more about the topic than the professor. In this article, I will offer some suggestions and advice for faculty creating a popular culture course for the first time, based on my experiences teaching undergraduates at the University of Notre Dame. The course I developed reflects my background in Japanese literature and film, and is but one example of many possible approaches to the topic. The sample syllabus and list of resources at the end of this article provide citations for all text and media sources mentioned.

  7. Prognostic value of normal stress myocardial perfusion imaging and ventricular function in Japanese asymptomatic patients with type 2 diabetes. A study of based on the J-ACCESS-2 database

    International Nuclear Information System (INIS)

    This study was designed to determine the clinical risk for hard events after normal single-photon emission computed tomography (SPECT) and to identify the predictors of increased risk in asymptomatic patients with diabetes mellitus, based on a Japanese Assessment of Cardiac Events and Survival Studies by quantitative gated SPECT (J-ACCESS)-2 study. A total of 513 consecutive asymptomatic patients who underwent stress 99mTc-tetrofosmin SPECT in Japan were included in this study. Based on SPECT image and QGS data, 319 had a summed stress score ≤3, a summed difference score <2 and normal cardiac function (end-systolic volume ≤60 ml, males, ≤40 ml females; left ventricular ejection fraction ≥49%, males, ≥50% females). Myocardial perfusion was normal in 62% of this study population. During a 3-year follow-up, there were a total of 8 cardiac major events (2.5%): 2 cases of sudden death, 5 of acute coronary syndrome, and 1 of hospitalization because of congestive heart failure. The annual major event rate was 0.8%. Subjects undergoing coronary angiography had significantly more major events than those who did not among normal SPECT subjects (P=0.01). Kaplan-Meier analysis showed that the cardiac major events rate was very low, and subjects with normal SPECT can be considered as low risk among asymptomatic patients with diabetes. An excellent prognosis was associated with a normal SPECT in asymptomatic patients with diabetes, so these patients can be exempted from further invasive procedure. (author)

  11. Optimisation of patient and staff exposure in interventional cardiology

    International Nuclear Information System (INIS)

    The Council Directive of the European Community 97/43/Euratom (MED) deals with the health protection of individuals against dangers of ionising radiation in relation to medical exposure, and also focuses attention on some special practices (Art. 9), including interventional radiology, a technique involving high doses to the patient. The paper presents the European approach to optimisation of exposure in interventional cardiology. The DIMOND research consortium (DIMOND: Digital Imaging: Measures for Optimising Radiological Information Content and Dose) is working to develop quality criteria for cineangiographic images, to develop procedures for the classification of complexity of therapeutic and diagnostic procedures and to derive reference levels, related also to procedure complexity. DIMOND project also includes aspects of equipment characteristics and performance and content of training in radiation protection of personnel working in interventional radiology field. (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

    This article presents the development of a Cardiology Electronic Health Record (CEHR) system. Software consists of a structured algorithm designed under Health Level-7 (HL7) international standards. Novelty of the system is the integration of high resolution ECG (HRECG) signal acquisition and processing tools, patient information management tools and telecardiology tools. Acquisition tools are for management and control of the DIGICARDIAC electrocardiograph functions. Processing tools allow management of HRECG signal analysis searching for indicative patterns of cardiovascular pathologies. Telecardiology tools incorporation allows system communication with other health care centers decreasing access time to the patient information. CEHR system was completely developed using open source software. Preliminary results of process validation showed the system efficiency.

  14. Categories by Heart: Shortcut Reasoning in a Cardiology Clinic

    Directory of Open Access Journals (Sweden)

    Katarina Jacobsson

    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.

    Full Text Available Abstract Background Differences in sex hormone levels among populations might contribute to the variation in breast cancer incidence across countries. Previous studies have shown higher breast cancer incidence and mortality among Japanese Brazilians than among Japanese. To clarify the difference in hormone levels among populations, we compared postmenopausal endogenous sex hormone levels among Japanese living in Japan, Japanese Brazilians living in the state of São Paulo, and non-Japanese Brazilians living in the state of São Paulo. Methods A cross-sectional study was conducted using a control group of case-control studies in Nagano, Japan, and São Paulo, Brazil. Participants were postmenopausal women older than 55 years of age who provided blood samples. We measured estradiol, estrone, androstenedione, dehydroepiandrosterone sulfate (DHEAS, testosterone and free testosterone by radioimmunoassay; bioavailable estradiol by the ammonium sulfate precipitation method; and sex hormone-binding globulin (SHBG by immunoradiometric assay. A total of 363 women were included for the present analyses, comprising 185 Japanese, 44 Japanese Brazilians and 134 non-Japanese Brazilians. Results Japanese Brazilians had significantly higher levels of estradiol, bioavailable estradiol, estrone, testosterone and free testosterone levels, and lower SHBG levels, than Japanese. Japanese Brazilians also had significantly higher levels of bioavailable estradiol, estrone and DHEAS and lower levels of SHBG and androstenedione than non-Japanese Brazilians. Levels of estradiol, testosterone and free testosterone, however, did not differ between Japanese Brazilians and non-Japanese Brazilians. These differences were observed even after adjustment for known breast cancer risk factors. We also found an increase in estrogen and androgen levels with increasing body mass index, but no association for most of the other known risk factors. Conclusions We found higher levels of

    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

  8. 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

  9. 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

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

  5. 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

  6. 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)

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.

  8. 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

  11. Recommendations for 18F-fluorodeoxyglucose positron emission tomography imaging for cardiac sarcoidosis. Japanese society of nuclear cardiology recommendations

    International Nuclear Information System (INIS)

    Sarcoidosis is a systemic granulomatous disease and generally the prognosis is good. However the prognosis of cardiac sarcoidosis (CS) is extremely poor and careful management is required. Guidelines for the diagnosis of CS were published in 1992 and modified in 2006 in Japan. Because the capability to diagnose CS has been improved through the use of 18F-FDG PET, The Japan Society of Sarcoidosis and other Granulomatous Diseases is currently updating its guidelines for the diagnosis of CS and positive 18F-FDG PET findings would be added for one of the criteria for the diagnosis. FDG PET Guidelines about preparation, scan protocol, image processing and image interpretation are described dealing with recommendations about dietary modification and fasting time before imaging, heparin preadministration, 18F-FDG administration dose, cardiac spot imaging, attenuation collection, use of bull's-eye map display, use of systemic MIP imaging and use of standardized uptake value.

  14. 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.

  15. 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.

    Full Text Available BACKGROUND Brugada syndrome, a disease burdened by elevated risk of sudden unexpected cardiac death, often affects young aged subjects that have structurally healthy heart. The diagnostic itinerary is complex: anamnesis, ECG, pharmacological test and electrophysiological study. Its phenotypes are three. METHOD We have identified 13 cases (10 men and 3 women, 12 estimated at the Cardiological Outpatients’ Department and 1 at the First-aid Station. RESULTS 2 cases belonged to phenotype 1, 4 cases to phenotype 2 and 7 cases to phenotype 3. CONCLUSIONS Our work of specialists in internal medicine, toward this syndrome, is: an accurate anamnesis, a correct interpretation of ECG, fast sending of high risk cases to advanced level cardiological competences, a selection of cases to submit to pharmacological test, to address middle risk patients to cardiological competences, offering our cooperation in the follow-up.

  2. 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

  3. 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

    We document the MRI features in seven patients with Japanese encephalitis. MRI was carried out on a 1.5 T system within 10-60 days of onset. In all the patients MRI revealed bilateral thalamic lesions, haemorrhagic in five. Signal changes were present in the cerebrum in four patients, the midbrain and cerebellum in three each, the pons in two and the basal ganglia in one. The lesions were haemorrhagic in three of the four patients with lesions in the cortex, two of the three with lesions in the midbrain and cerebellum, but the pontine lesions were haemorrhagic in both patients. Spinal cord involvement was seen in one of the three patients who underwent MRI. In two patients MRI was repeated 3 years after the onset, showing marked reduction in abnormal signal; and all the lesions gave low signal on both T1- and T2-weighted images. Bilateral thalamic involvement, especially haemorrhagic, may be considered characteristic of Japanese encephalitis, especially in endemic areas. (orig.)

    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

  8. 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

    Full Text Available Review of: James Boyd. 2011. Japanese-Mongolian Relations, 1873-1945: Faith, Race and Strategy. Kent: Global Oriental. Japanese individuals were among the many foreigners with interests in Mongolia in the nineteenth and twentieth centuries. With the Soviet Union to the north and the Republic of China to the south, Japanese political, military, scholarly, business, and Buddhist elites were among those attentive to the region's strategic position. Since the collapse of the Soviet Union, scholars of Japan, as well as Japanese scholars, have widely contributed to dispelling myths of Mongolia's isolation, as well as to unraveling the complex geopolitical relationships between Manchuria, Russia, Mongolia, China, and Japan. Focusing on the period 1873 to 1945, and dealing with a range of topics beyond strategic political and military concerns, Boyd's seminal work explores the implications of Japanese understandings of the cultural relationships between Japan and Inner Mongolia, the so-called buffer zone between 'Outer' Mongolia and the Republic of China. Limiting his focus to Japanese perspectives during that period has permitted a comprehensive evaluation of the intricate interdependencies of Japan's non-military and military activities.

  15. 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

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

    2010-07-01

    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

  17. 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

  18. Japanese Hadron Project

    International Nuclear Information System (INIS)

    The Japanese Hadron Project (JHP) is aimed at producing various kinds of unstable secondary beams based on high-intensity protons from a new accelerator complex. The 1 GeV protons, first produced from a 1 GeV linac, are transferred to a compressor/stretcher ring, where a sharply-pulsed beam or a stretched continuous beam will be produced. The pulsed beam will be used for a pulsed muon source (M arena) and a spallation neutron source (N arena). A part of the proton beam will be used to produce unstable nuclei, which will be accelerated to several MeV/nucleon (E arena). The purpose and impact of JHP will be described in view of future applications of hadronic beams to nuclear energy and material science. (author)

    Although Japanese tourists in Hawaii are infrequently treated for acute psychiatric emergencies, we observed several cases among Japanese honeymooners. To investigate this phenomenon, we retrospectively and prospectively collected such cases of honeymooners. Sixteen cases of acute psychiatric disturbance in Japanese honeymooners in Hawaii are described. This phenomenon occurs more frequently than in other Japanese tourists or non-Japanese honeymooners. The tradition of arranged marriage and other cultural factors may be associated with the potential for "honeymoon psychosis." PMID:9277018

  3. Mechanistic modeling of transition temperature shift of Japanese RPV materials

    International Nuclear Information System (INIS)

    A new correlation method to predict neutron irradiation embrittlement of reactor pressure vessel (RPV) materials of Japanese nuclear power plants is developed based on the understandings of the embrittlement mechanisms. A set of rate equations is constructed to describe the microstructural changes in the RPV materials during irradiation. Formation of copper-enriched clusters (CEC) and matrix damage (MD) are considered as the two primary causes of the embrittlement. Not only the effects of chemical compositions, such as copper and nickel, and neutron fluence, but also the effects of irradiation temperature as well as neutron flux are formulated in the rate equations to describe the evolution of CEC and MD. Transition temperature shifts corresponding to the microstructural changes are calculated using the predicted number densities of the CEC and MD. Coefficients of the rate equations are optimized using the Japanese surveillance database with a specific attention to reproduce the embrittlement trend of each material of the Japanese RPVs. The standard deviation of 12.1 C of the current Japanese correlation method, JEAC 4201, is reduced down to 10.6 C in the proposed new correlation method. Possibility of adjusting the uncertainty in the initial transition temperatures is discussed. (orig.)

  6. 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

Future opportunities for improvement of the risk-benefit ratio in each patient are the main purpose of the collection and analysis of pharmacogenetic data.

  8. Reference Japanese man

    International Nuclear Information System (INIS)

    The distribution of stable strontium concentration in different bones, as well as in a single bone, was studied. Dependence of the stable strontium-to-calcium ratio upon age was observed. A non-uniform distribution of the stable strontium to calcium ratio was found in both the skeleton and the single bone. It was suggested that this phenomenon may be used in predicting 90Sr distribution in the human skeleton. Concentrations of stable strontium in bone were found to be relatively higher than reported data. The total skeletal content of strontium was re-estimated, taking into account the observed uneven distribution of this element in the skeleton. The observed ratio between the adult bone and diet was found to be 0.12 and that between fetal bone and the mother's diet 0.055. These values seem considerably lower than the reported data for the European and North American populations. The mass of ''mineralized bone'' of the Japanese adult male and female was estimated as 4.2 kg and 3.2 kg, respectively. (author)

  15. 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.

    In this study, we measure the colors used in a Japanese Animations. The result can be seen on CIE-xy color spaces. It clearly shows that the color system is not a natural appearance system but an imagined and artistic appearance system. Color constancy of human vision can tell the difference in skin and hair colors between under moonlight and day light. Human brain generates a match to the memorized color of an object from daylight viewing conditions to the color of the object in different viewing conditions. For example, Japanese people always perceive the color of the Rising Sun in the Japanese flag as red even in a different viewing condition such as under moonlight. Color images captured by a camera cannot present those human perceptions. However, Japanese colorists in Animation succeeded in painting the effects of color constancy not only under moonlight but also added the memory matching colors. They aim to create a greater impact on viewer's perceptions by using the effect of the memory matching colors. In this paper, we propose the Imagined Japanese Animation Color System. This system in art is currently a subject of research in Japan. Its importance is that it could also provide an explanation on how human brain perceives the same color under different viewing conditions.

  9. 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)

    2016-05-01

    Pulmonary edema is a frequent condition found in adult patients hospitalized in cardiology wards and intensive care units. Ultrasonography is a diagnostic modality with a high sensitivity for the detection of extravascular lung water, visualized as B lines, and usually caused by cardiogenic or noncardiogenic pulmonary edema. This paper highlights a simple method for the assessment of patients with pulmonary edema, which allows for a differential diagnosis of its possible mechanism and contributes to therapeutic intervention guiding and monitoring.

    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.

    In this paper, we analyze how the volume of rice imports would be affected if the Japanese government were to reduce tariffs on rice by looking at the current state of the Simultaneous Buy-and-Sell (SBS) system for rice imports. The Japanese government is required to import 770,000 tons of rice per year to maintain minimum access. However, a large portion of minimum access rice is not used for domestic consumption—only 100,000 tons of SBS rice is used for human consumption. Under the SBS syst...

  15. 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

  18. Marine biodiversity in Japanese waters.

    Directory of Open Access Journals (Sweden)

    Katsunori Fujikura

    Full Text Available To understand marine biodiversity in Japanese waters, we have compiled information on the marine biota in Japanese waters, including the number of described species (species richness, the history of marine biology research in Japan, the state of knowledge, the number of endemic species, the number of identified but undescribed species, the number of known introduced species, and the number of taxonomic experts and identification guides, with consideration of the general ocean environmental background, such as the physical and geological settings. A total of 33,629 species have been reported to occur in Japanese waters. The state of knowledge was extremely variable, with taxa containing many inconspicuous, smaller species tending to be less well known. The total number of identified but undescribed species was at least 121,913. The total number of described species combined with the number of identified but undescribed species reached 155,542. This is the best estimate of the total number of species in Japanese waters and indicates that more than 70% of Japan's marine biodiversity remains un-described. The number of species reported as introduced into Japanese waters was 39. This is the first attempt to estimate species richness for all marine species in Japanese waters. Although its marine biota can be considered relatively well known, at least within the Asian-Pacific region, considering the vast number of different marine environments such as coral reefs, ocean trenches, ice-bound waters, methane seeps, and hydrothermal vents, much work remains to be done. We expect global change to have a tremendous impact on marine biodiversity and ecosystems. Japan is in a particularly suitable geographic situation and has a lot of facilities for conducting marine science research. Japan has an important responsibility to contribute to our understanding of life in the oceans.

  19. JABEE in Japanese Engineering Education

    Science.gov (United States)

    Takeda, Kunihiko; Ishikawa, Tomoyuki

    JABEE in Japanese engineering education is discussed by focusing on the status and treatment of engineers in Japanese society and their achievements. The entrance fee and tuition of the engineering departments of higher education facilities are higher than those of the law, economy and literature departments. On the other hand, an engineer's lifelong wage is smaller than that of those who have graduated from the latter fields. Although engineering students must study for a longer period of time, the scholarship system to support these students in Japan falls far behind that in the U.S.A. The achievements of Japanese engineering were summarized from the viewpoint of economic indications such as 1) production of steel, 2) energy consumption per person as a function of GDP, 3) income 4) real estate abroad and miscellaneous factors such as the life spans and criminal rates of many countries. These analyses made it clear that Japanese engineers have the highest ability even compared to advanced countries and this is because of the higher engineering education in Japan ; but their status is unreasonably low in Japanese society. The four points by which the present status of Japanese engineers can be improved were discussed in relation to the introduction and the achievement of the JABEE system. The true aim of education reform by JABEE is that the engineering education in Japan should shift “from government to non-government”, “from organization to individual” and “from control to interdependency.” The expected points of improvement are discussed.

    An integrated energy database should be prepared in advance for managing energy statistics comprehensively. However, since much manpower and budget is required for developing an integrated energy database, it is difficult to establish a database within a short period of time. Therefore, this study sets the purpose in drawing methods to analyze existing statistical data lists and to consolidate insufficient data as first stage work for the energy database, and at the same time, in analyzing general concepts and the data structure of the database. I also studied the data content and items of energy databases in operation in international energy-related organizations such as IEA, APEC, Japan, and the USA as overseas cases as well as domestic conditions in energy databases, and the hardware operating systems of Japanese databases. I analyzed the making-out system of Korean energy databases, discussed the KEDB system which is representative of total energy databases, and present design concepts for new energy databases. In addition, I present the establishment directions and their contents of future Korean energy databases, data contents that should be collected by supply and demand statistics, and the establishment of data collection organization, etc. by analyzing the Korean energy statistical data and comparing them with the system of OECD/IEA. 26 refs., 15 figs., 11 tabs.

    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.

  4. Extremity doses of medical staff involved in interventional radiology and cardiology: Correlations and annual doses (hands and legs)

    International Nuclear Information System (INIS)

    An intensive measurement campaign was launched in different hospitals in Europe within work package 1 of the ORAMED project (Optimization of RAdiation protection for MEDical staff). Its main objective was to obtain a set of standardized data on extremity and eye lens doses for staff in interventional radiology (IR) and cardiology (IC) and to optimize staff protection. The monitored procedures were divided in three main categories: cardiac, general angiography and endoscopic retrograde cholangio-pancreatography(ERCP) procedures. Using a common measurement protocol, information such as the protective equipment used (lead table curtain, transparent lead glass ceiling screen, patient shielding, whole body shielding or special cabin etc.) as well as Kerma Area Product (KAP) values and access of the catheter were recorded. This study was performed with a final database of more than 1300 procedures performed in 34 European hospitals. Its objectives were firstly to determine if the measured extremity doses could be correlated to the KAP values; secondly to check if the doses to the eyes could be linked to the doses to the hands (finger or wrist positions) and finally if the doses to the fingers could be estimated based on the doses to the wrists. General correlations were very difficult to find and their strength was mostly influenced by three main parameters: the X-ray tube configuration, the room collective radioprotective equipment and the access of the catheter. The KAP value can provide a simple mean to estimate the extremity doses of the operator given that it is assessed correctly for the operator when he is actually using the X-ray tube. Moreover, this study showed that the doses to the left finger are strongly correlated to the doses to the left wrist when no ceiling shield is used. It is also possible to estimate the doses to the eyes given the doses to the left finger or left wrist but the X-ray tube configuration and the access have to be considered. The annual

  6. 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.

    2015-05-01

    Full Text Available Cardiovascular diseases are the main causes of mortality and morbidity in Brazil. Their primary and secondary preventions are a priority for the health system and require multiple approaches for increased effectiveness. Biomarkers are tools used to identify with greater accuracy high-risk individuals, establish a faster diagnosis, guide treatment, and determine prognosis. This review aims to highlight the importance of biomarkers in clinical cardiology practice and raise relevant points regarding their application and perspectives for the next few years. This document was divided into two parts. This second part addresses the application of biomarkers in coronary heart disease, valvular diseases, cardio-oncology, pulmonary embolism, and cardiorenal syndrome.

    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

    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.

  2. Stakeholder involvement - a japanese perspective

    International Nuclear Information System (INIS)

    Traditional societal and cultural background of Japanese in general indicates the intrinsic difficulty in involving the public as stakeholders in the process of any type of decision making in policy matters. It is characterized by the long-taught virtue of harmonization and obedience to others. In addition, characteristic system of Japanese traditional industrial society, such as lifetime employment, seniority-based wage system, and enterprise-based labour union, encourages the loyalty to the employer/company, but not to the public. The public or ordinary citizens would seldom come out as stakeholders and express their true feelings or real opinions, even though younger generation is notably getting out from such a trend. On the other hand, it is a common practice in Japanese society for any business or administrative transactions to try to obtain 'consensus' among relevant parties concerned (stakeholders) by negotiations behind the curtain prior to the formal discussion. In this sense, 'stakeholders involvement' is accepted and practised as a matter of course, but mostly for actions between parties of equivalently influential status levels or between 'directly relevant' parties such as those between the different government agencies, between regulators and industries. The concept of 'Involving the public in decision making as stakeholders' is not yet fully understood nor accepted in Japan both by regulators and by the public so far as the issue of radiation protection is concerned. These situations are explained with some examples. (author)

    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.

This analysis is supplemented by writings by Japanese architects and poets. The principal elements of Japanese architecture are: (1 ma, and (2 en. Ma is usually translated as ‘interval’ because, like the English word, it applies to both space and time.  However, in Japanese thinking, it is not so much an either/or, but rather a both/and. In other words, Japanese architecture emphasises the temporal aspect of dwelling in a way that Western architectural thinking usually does not. En means ‘joint, edge, the in-between’ as an ambiguous, often asymmetrical spanning of interior and exterior, rather than a demarcation of these regions. Both elements are aimed at producing an experience of temporality and transiency.

  13. 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)

  14. 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.

  16. 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.

  17. 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)

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

    Science.gov (United States)

    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.

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.

    Full Text Available Relational databases ruled the Information Technology (IT industry for almost 40 years. But last few years have seen sea changes in the way IT is being used and viewed. Stand alone applications have been replaced with web-based applications, dedicated servers with multiple distributed servers and dedicated storage with network storage. Cloud computing has become a reality due to its lesser cost, scalability and pay-as-you-go model. It is one of the biggest changes in IT after the rise of World Wide Web. Cloud databases such as Big Table, Sherpa and SimpleDB are becoming popular. They address the limitations of existing relational databases related to scalability, ease of use and dynamic provisioning. Cloud databases are mainly used for data-intensive applications such as data warehousing, data mining and business intelligence. These applications are read-intensive, scalable and elastic in nature. Transactional data management applications such as banking, airline reservation, online e-commerce and supply chain management applications are write-intensive. Databases supporting such applications require ACID (Atomicity, Consistency, Isolation and Durability properties, but these databases are difficult to deploy in the cloud. The goal of this paper is to review the state of the art in the cloud databases and various architectures. It further assesses the challenges to develop cloud databases that meet the user requirements and discusses popularly used Cloud databases.

  7. 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

  8. Are the Cochrane group registers comprehensive? A case study of Japanese psychiatry trials

    2002-04-01

    Full Text Available Abstract Background Language bias is a form of publication bias and constitutes a serious threat to meta-analyses. The Cochrane Controlled Trials Register is one attempt to remedy this and now contains more than 300,000 citations. However we are still unsure if it provides comprehensive coverage, particularly for non-English trials. Methods We have recently established a comprehensive register of Japanese trials of psychotropic drugs through extensive personal contacts, electronic searches and handsearches. We examined two Cochrane psychiatry group registers against this Japanese database. Results The Japanese register contained 56 reports of randomized controlled trials (RCTs of antidepressants for depression but the Cochrane Depression, Anxiety and Neurosis group register contained 18, with an overlap of only nine. The Japanese register contained 61 reports of RCTs of neuroleptics for schizophrenia and the Cochrane Schizophrenia group register contained 36, with an overlap of only six. Taking account of some duplicate publications, only a quarter to a third of all relevant Japanese RCTs were retrievable from the Cochrane group registers. Conclusions Similar, or worse, yields may be expected with RCTs conducted in other East Asian countries, and in other fields of medicine. What evidence there is suggests that this situation may lead to a systematic over estimate of treatment effect.

    2013-01-01

    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

  10. 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

  11. 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)

  13. 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.

  14. 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.

  20. 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)

    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

    In this study, CT findings of eight patients with Japanese encephalitis were analyzed. In principle, CT scans were done at the acute stage, within 3 weeks of the onset, and at the convalescent stage, after from 1 month to 1 year. The results may be divided into three groups: normal scans, low-density lesions, and ventricular abnormalities. 1) Normal scans: CT findings in Cases 1 and 5, showed no abnormalities, although patient 5 had clinically severe encephalitis. 2) Low-density lesions: In Case 3, a slight low-density area was observed in the bilateral thalami only at the acute stage. CT scans in Case 4, obtained 2 and 4 months after the onset, exhibited low-density areas in the bilateral thalami, the left basal ganglia, and the left substantia nigra. In Case 7, diffuse low-density areas in the white matter were found 3 months after the onset. 3) Ventricular abnormalities: CT in Case 2 revealed a moderate dilatation of the ventricular system, which probably suggests normal-pressure hydrocephalus. In 2 other cases, a narrowing or dilatation of the lateral ventricle was observed. The CT findings regarding Japanese encephalitis were discussed in comparison with those of other viral encephalitides, particularly herpes simplex encephalitis.

  13. The Japanese gas utility industry

    International Nuclear Information System (INIS)

    This paper reports the Japanese gas utility industry which is composed of some 240 gas utilities of varying sizes, and the form of gas distribution between the three major gas companies and the other gas utilities are quite different. The three major gas companies distribute principally natural gas processed from imported LNG and their sales account for over 70 percent of all gas sold in Japan. The other utilities, smaller in scale, manufacture and market gas produced mainly from such feedstocks as naptha and LPG. Gas accounts for a relatively small share in the country's final energy consumption. The 3.1 percent market share has grown to 4.8 percent between 1976 and 1986. Japan's energy consumption is large in the industrial sector and small in the residential sector. The gas consumption, however, features the opposite situation, in which gas accounts for 15.7 percent in the residential sector, and only 1.9 percent in the industrial sector in 1986. This is one of the salient characteristics of the gas industry of the country as compared with Europe and the United States, where gas has a market share of 20 to 40 percent in both residential and industrial sectors. This paper presents and discusses reasons for the small share of natural gas in the Japanese market

  14. 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)

    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)

    2016-02-01

    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

  17. 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.

    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.

La terapia eléctrica cumple las leyes de la electricidad y el mayor factor a vencer es la impedancia o resistencia al flujo de electrones. Para mejorar la efectividad de la terapia eléctrica se han ideado diferentes formas en la onda de choque, en la duración y la polaridad. La terapia eléctrica ha logrado consolidarse como el tratamiento de elección del paro cardiorrespiratorio secundario a fibrilación ventricular y taquicardia ventricular sin pulso. Es igualmente el tratamiento de elección en taquiarritmias con compromiso hemodinámico. Pese a sus grandes ventajas tiene efectos secundarios que se deben conocer adecuadamente para dar un tratamiento oportuno.Electrical shock in cardiology are pursuid transfer of electrons to the myocardium. 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.

    institute, with the death records of the state of Rio de Janeiro, Southeastern Brazil, in 2005. Linkage was conducted in four stages: standardizing the databases, blocking, matching, and rating peers. Blocking in five steps was used, with blocking keys formed by a combination of variables such as soundex codes for the first and last names, sex, and year of birth. The variables used for matching were "full name" with the use of Levenshtein distance and "birth date". RESULTS: The second and fifth blocking steps resulted in the largest number of formed pairs and the largest processing times for the matching. The fourth step required a lower processing cost. In the accuracy study, after five blocking steps, the sensitivity of the linkage was 90.6%, and the specificity was 100%. CONCLUSIONS: The probabilistic strategy used has high accuracy and can be used in studies of the effectiveness of high-complexity, high-cost cardiology procedures.

  14. Japanese strategy of fusion roadmap

    International Nuclear Information System (INIS)

    Technology bases required for realization of a fusion demonstration reactor (DEMO) have been discussed in the Japanese fusion community. The Join-Core Team, which was launched by ministerial council, has considered the following issues to develop strategy for the establishment of technology bases for a DEMO: (1) Concept of DEMO premised for investigation, (2) Activities requiring commitment and their goals, and (3) Scientific and technological review works for the above mentioned activities. The team summarized the issues as Joint-Core Team Report (Basic Concept of DEMO and Structure of Technological Issues). This report describes the basic concept of DEMO premised for investigation and the structure of technological issues to ensure the feasibility of the DEMO concept. Also the team clarified tasks regarding the development of the design of DEMO, and the research and development programs to resolve the issues and to provide the required evidence to support the design into the consistent timeline, which is summarized in the second Joint-Core Team Report (Chart of Establishment of Technology Bases for DEMO). The reports show that DEMO is steady power generator with several hundred thousand kilowatts being able to extend to commercialization. Also function of tritium bleeding to fulfil self-sufficiency of fuels should be equipped. Required technological activities (superconducting coils, blanket, divertor, heating and current drive systems etc.) are arranged in the chart. JAEA has established the Joint Special Design Team for Fusion DEMO in cooperation with NIFS, industry, and universities and reinforces design activity of a tokamak DEMO. Two important tasks still remain to define the roadmap of development of DEMO in future, that is, socio-economic examination of fusion energy and review of alternative approaches of helical magnetic fusion system and laser fusion system. In particular, solution of the latter task should be found under the deep discussion with

  19. Japanese lifestyle during childhood prevents the future development of obesity among Japanese-Americans.

    Directory of Open Access Journals (Sweden)

    Mami Shiwa

    Full Text Available To evaluate whether a Japanese lifestyle during childhood could protect against the future development of obesity-associated metabolic diseases by comparing native Japanese with Japanese-Americans in whom genetic factors are the same.Study subjects were 516 native Japanese and 781 Japanese-Americans who underwent medical examinations between 2007 and 2010. Japanese-Americans were divided into 444 first-generation immigrants (JA-1, who were born in Japan, and 337 second- or later-generation descendants (JA-2, who were born in the United States. The JA-2 group was then divided into the kibei subgroup (N = 79, who had moved to Japan before the age of 18 years and later returned to the United States, and the non-kibei subgroup (N = 258, who had never lived in Japan.The JA-2 group had the highest percentages of obesity, metabolic syndrome, and type 2 diabetes compared with native Japanese and JA-1. Furthermore, among JA-2, the prevalence of obesity and metabolic syndrome in the kibei subgroup was significantly lower than that in the non-kibei subgroup. The prevalence of diabetes in the kibei subgroup also tended to be lower than in the non-kibei subgroup.The prevalence of obesity and metabolic diseases differed with residence in Japan during childhood among Japanese-Americans. These findings indicate the possibility that Japanese lifestyle during childhood could reduce the future risks for obesity-associated metabolic diseases.

    2013-06-01

    Full Text Available A major learning difficulty of Japanese foreign language (JFL learners is the complex composition of two syllabaries, hiragana and katakana, and kanji characters adopted from logographic Chinese ones. As the number of Japanese language learners increases, computer-assisted Japanese language education gradually gains more attention. This study aimed to adopt a Japanese word segmentation system to help JFL learners overcome literacy problems. This study adopted MeCab, a Japanese morphological analyzer and part-of-speech (POS tagger, to segment Japanese texts into separate morphemes by adding spaces and to attach POS tags to each morpheme for beginners. The participants were asked to participate in three experimental activities involvingwatching two Japanese videos with general or segmented Japanese captions and complete the Nielsen’s Attributes of Usability (NAU survey and the After Scenario Questionnaire (ASQ to evaluate the usability of the learning activities. The results of the system evaluation showed that the videos with the segmented captions could increase the participants’ learning motivation and willingness to adopt the word segmentation system to learn Japanese.

    Full Text Available Almost every organization has at its centre a database. The database provides support for conducting different activities, whether it is production, sales and marketing or internal operations. Every day, a database is accessed for help in strategic decisions. The satisfaction therefore of such needs is entailed with a high quality security and availability. Those needs can be realised using a DBMS (Database Management System which is, in fact, software for a database. Technically speaking, it is software which uses a standard method of cataloguing, recovery, and running different data queries. DBMS manages the input data, organizes it, and provides ways of modifying or extracting the data by its users or other programs. Managing the database is an operation that requires periodical updates, optimizing and monitoring.

  3. Conditioning Probabilistic Databases

    CERN Document Server

    Koch, Christoph

    2008-01-01

    Past research on probabilistic databases has studied the problem of answering queries on a static database. Application scenarios of probabilistic databases however often involve the conditioning of a database using additional information in the form of new evidence. The conditioning problem is thus to transform a probabilistic database of priors into a posterior probabilistic database which is materialized for subsequent query processing or further refinement. It turns out that the conditioning problem is closely related to the problem of computing exact tuple confidence values. It is known that exact confidence computation is an NP-hard problem. This has lead researchers to consider approximation techniques for confidence computation. However, neither conditioning nor exact confidence computation can be solved using such techniques. In this paper we present efficient techniques for both problems. We study several problem decomposition methods and heuristics that are based on the most successful search techn...

    Walker, M; Côté, S; Walker, Marilyn; Iida, Masayo; Cote, Sharon

    1996-01-01

    This paper has three aims: (1) to generalize a computational account of the discourse process called {\\sc centering}, (2) to apply this account to discourse processing in Japanese so that it can be used in computational systems for machine translation or language understanding, and (3) to provide some insights on the effect of syntactic factors in Japanese on discourse interpretation. We argue that while discourse interpretation is an inferential process, syntactic cues constrain this process, and demonstrate this argument with respect to the interpretation of {\\sc zeros}, unexpressed arguments of the verb, in Japanese. The syntactic cues in Japanese discourse that we investigate are the morphological markers for grammatical {\\sc topic}, the postposition investigate the role of speaker's {\\sc empathy}, which is the viewpoint from which an event is described. This is syntactically indicated through the use of verbal compounding, i.e. the auxiliary use of verbs such as {\\it kureta, kita}. Our results are based ...

    Irena SRDANOVIĆ

    2011-10-01

    Full Text Available In this paper, we present results of an evaluation of Japanese word sketches and address in detail issues that were observed by the evaluators. A word sketch presents a list of salient collocates of a word, organized by the grammatical relations holding between the word and its collocate. The word sketch functionality is incorporated into the Sketch Engine corpus query system and has been created for more than twenty languages so far, including Japanese. The issues that have been discovered in the evaluation of word sketches in Japanese are to be addressed for further enhancement of the word sketch functionality. Other tools and resources which are combined for use and influence the performance of the word sketches should also be looked over. We divide the issues into the following: 1 the lemmatizer and tagger in use, 2 the sketch grammar that is specifically written for Japanese, and 3 the corpus and statistical methods.

  6. The Japanese approach to financing LNG projects

    International Nuclear Information System (INIS)

    The Japanese approach approach to financing LNG project has been what could be called a combined purchase and finance system which has been arranged mainly at the initiative of japan's Sogo Shosh (general trading companies) with the support of japanese governmental financial agencies and a purchase commitment from japanese utilities. In the QATARGAS project, despite it being the first greenfield LNG project in decade since North West Shelf Australia LNG project, financing for the LNG plant phase has been successfully arranged through Japanese financing. The structuring of the financial facilities for the QATARGAS project seems to have lessons for future development of the next generation of greenfield LNG projects. Discharge of the parties' liability, proper sharing of the risk burden and reconfirmation of the spirit of mutual understanding and trust among the parties concerned are key factors for the success of any new LNG project in the future.

    Full Text Available Forecasts of prices can help industries in their risk management. This is especially true for Japanese logs, which experience sharp fluctuations in price. In this research, the authors used an exponential smoothing method (ETS and autoregressive integrated moving average (ARIMA models to forecast the monthly prices of domestic logs of three of the most important species in Japan: sugi (Japanese cedar, Cryptomeria japonica D. Don, hinoki (Japanese cypress, Chamaecyparis obtusa (Sieb. et Zucc. Endl., and karamatsu (Japanese larch, Larix kaempferi (Lamb. Carr.. For the 12-month forecasting periods, forecasting intervals of 80% and 95% were given. By measuring the accuracy of forecasts of 12- and 6-month forecasting periods, it was found that ARIMA gave better results than did the ETS in the majority of cases. However, the combined method of averaging ETS and ARIMA forecasts gave the best results for hinoki in several cases.

  11. How changes to the Medicare Benefits Schedule could improve the practice of cardiology and save taxpayer money.

    Harper, Richard W; Nasis, Arthur; Sundararajan, Vijaya

    2015-09-21

    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.

  12. 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

  3. Compilation of INES (International Nuclear Event Scale) information. Japanese translation (Vol.2)

    International Nuclear Information System (INIS)

    The International Nuclear Event Scale (INES) is a means designed for providing prompt, clear and consistent information related to nuclear events, that occurred at nuclear power plants and at other nuclear facilities, and facilitating communication between the nuclear community, the media and the public on such events. The INES is jointly operated by the International Atomic Energy Agency (IAEA) and the Nuclear Energy Agency of the Organization for Economic Co-operation and Development (OECD/NEA). Nuclear events reported to the INES Information System from member countries of IAEA and/or OECD/NEA are rated by the 'Scale', a consistent safety significance indicator. The scale runs from level 0, for events with no safety significance, to level 7 for a major accident with widespread health and environmental effects. The INES was introduced in March 1990 for a trial and then formally adopted in March 1992. In Japan, the INES was formally introduced in August 1992. The Japan Atomic Energy Research Institute (JAERI) has been receiving the INES information through the Science and Technology Agency, promptly translating into Japanese and providing to the relevant sections inside and outside JAERI. As well, we published the report compiling the Japanese translation of individual INES reports until May 31, 1998. Since then, we have developed a world-wide-web database for the Japanese translation and made it available to the public through the internet. This report compiles the Japanese version of approximately 70 INES reports we received from June 1, 1998 to December 31, 2000. (author)

    Nolen-Hoeksema, R. (Stanford Univ., CA (United States)); Hart, C. (Envision Systems, Inc., Fremont, CA (United States))

    The authors have developed a relational database for the Stanford Rock Physics (SRP) Laboratory. The database is a flexible tool for helping researchers find relevant data. It significantly speeds retrieval of data and facilitates new organizations of rock physics information to get answers to research questions. The motivation for a database was to have a computer data storage, search, and display capability to explore the sensitivity of acoustic velocities to changes in the properties and states of rocks. Benefits include data exchange among researchers, discovery of new relations in existing data, and identification of new areas of research. The authors' goal was to build a database flexible enough for the dynamic and multidisciplinary research environment of rock physics. Databases are based on data models. A flexible data model must: (1) Not impose strong, prior constraints on the data; (2) not require a steep learning curve of the database architecture; and (3) be easy to modify. The authors' choice of the relational data model reflects these considerations. The database and some hardware and software considerations were influenced by their choice of data model, and their desire to provide a user-friendly interface for the database and build a distributed database system.

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. In the long-term course of treatment

    Full Text Available Cardiology has been and is a very significant fraction of the Brazilian contribution to science. In older days, the most significant part of this work was directed to foreign periodicals, but the quasi-simultaneous emergence of SciELO and PUBMED has ordained a redirection of much of this work to Brazilian periodicals. We here survey some of this more recent contribution for the benefit of readers of Revista Brasileira de Cirurgia Cardiovascular. This is offered as an update. Articles on the general themes of Cardiology and Pneumology published by four ISI Indexed Brazilian journals not specializing in cardiology are re-visited, after a search through 10 journals.A Cardiologia foi, e continua sendo, responsável por uma fracção muito significativa da contribuição brasileira para a ciência. No passado, os trabalhos mais importantes eram direcionados para periódicos estrangeiros, mas o surgimento quase simultâneo do SciELO e PUBMED facilitou um redirecionamento de grande parte desses trabalhos a periódicos brasileiros. Neste artigo, examinamos algumas das contribuições mais recentes em benefício aos leitores da Revista Brasileira de Cirurgia Cardiovascular. Esta discussão é oferecida como uma atualização. Artigos sobre os temas gerais da cardiologia e pneumologia publicados por quatro revistas brasileiras indexadas no ISI - não especializadas em cardiologia - são revistos.

  8. Challenging the holy grail of hospital accreditation: A cross sectional study of inpatient satisfaction in the field of cardiology

    Science.gov (United States)

    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

    Sudden cardiac death (SCD) is a common cause of death in hypertrophic cardiomyopathy (HC). Our aim was to conduct an external and independent validation in South America of the 2014 European Society of Cardiology (ESC) SCD risk prediction model to identify patients requiring an implantable cardioverter defibrillator. This study included 502 consecutive patients with HC followed from March, 1993 to December, 2014. A combined end point of SCD or appropriate implantable cardioverter defibrillator therapy was assessed. For the quantitative estimation of individual 5-year SCD risk, we used the formula: 1 - 0.998(exp(Prognostic index)). Our database also included the abnormal blood pressure response to exercise as a risk marker. We analyzed the 3 categories of 5-year risk proposed by the ESC: low risk (LR) <4%; intermediate risk (IR) ≥4% to <6%, and high risk (HR) ≥6%. The LR group included 387 patients (77%); the IR group 39 (8%); and the HR group 76 (15%). Fourteen patients (3%) had SCD/appropriate implantable cardioverter defibrillator therapy (LR: 0%; IR: 2 of 39 [5%]; and HR: 12 of 76 [16%]). In a receiver-operating characteristic curve, the new model proved to be an excellent predictor because the area under the curve for the estimated risk is 0.925 (statistical C: 0.925; 95% CI 0.8884 to 0.9539, p <0.0001). In conclusion, the SCD risk prediction model in HC proposed by the 2014 ESC guidelines was validated in our population and represents an improvement compared with previous approaches. A larger multicenter, independent and external validation of the model with long-term follow-up would be advisable. PMID:27189816

    2015-01-01

    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.

  7. 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.)

  8. 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)

  9. 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)

    2012-01-01

    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.

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

    Ambrosio, Giuseppe; Komajda, Michel; Mugelli, Alessandro; Lopez-Sendón, José; Tamargo, Juan; Camm, John

    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

    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.

  14. 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.

    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)

  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. 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

  18. 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.

    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.)

  20. 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.

    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.

    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.

    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.

    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.

    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.

  19. 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.)

    A variety of protein sequence databases exist, ranging from simple sequence repositories, which store data with little or no manual intervention in the creation of the records, to expertly curated universal databases that cover all species and in which the original sequence data are enhanced by the manual addition of further information in each sequence record. As the focus of researchers moves from the genome to the proteins encoded by it, these databases will play an even more important role as central comprehensive resources of protein information. Several the leading protein sequence databases are discussed here, with special emphasis on the databases now provided by the Universal Protein Knowledgebase (UniProt) consortium. PMID:15036160
