    Routine chest X-ray often yields poor information for diagnosis of heart disease. The diagnostic value of invasive procedures in cardiology is generally accepted. The patient's as well as the physician's risk of the examination, however, has to be considered. A high number of heart diseases, e.g. hypertrophic obstructive cardiomyopathy (HOCM) is mainly detected by noninvasive procedures such as auscultation, electrocardiography, phonomechanocardiography, echocardiography, physical manoeuvres, and pharmacological provocation tests. Typical findings in hypertrophic obstructive cardiomyopathy are demonstrated. (orig.) [de

    In extrahepatic cholestasis it is necessary to include Mirizzi's syndrome in the differential diagnostic considerations. Characteristic findings in sonography and computed tomography ae: a stone incorporated in the neck of the gallbladder or cystic duct with an extension of the common hepatic duct above the stone and normal width of the bile duct below the sone; in endoscopic retrograde cholangiography (ERC, direkt cholangiography), a characteristic finding is a smooth-walled, segmental stenosis through external compression or an incorporated stone.

    1987-01-01

    The clinical and radiological features of viral pneumonias are summarized and discussed. Although viral infections of the lung belong to atypical pneumonias they demonstrate not always the radiographic pattern of an interstitial pneumonia. Characteristic radiographic findings are quite rare. In most cases the microbial etiology cannot be predicted from chest radiographs. The appearance varies depending on the virulence of the organism and the resistence of the host. In this regard knowledge of epidemiological data as well as patients condition and underlying disease is of utmost importance. Differentiation between community- and hospital-acquired infection may be very helpful. (orig.) [de

    Three cases of craniopharyngiomas with atypical MRI findings are reported. The first patient had a nasopharyngeal craniopharyngioma. Its unusual location made diagnosis difficult. The second patient had a massive craniopharyngioma with extensive cystic expansion, involving the anterior, middle and posterior cranial fossae, and extending into the foramen magnum. The tumour of the third patient involved the suprasellar region with a large extension into the third ventricle, and demonstrated a predominantly high signal intensity on all T1-weighted, proton-weighted and T2-weighted images. These patients further stressed the complexity of MRI findings in craniopharyngiomas. Copyright (2001) Blackwell Science Pty Ltd

    The evaluation of dose to physicians involved in Interventional Cardiology (IC) is an extreme important matter due to the high and non-uniform distribution of dose values. The radiation control during each procedure is complex and the reasons for the high exposures have many different causes. Many international recommendations have already been written aiming the radiation protection optimization in IC. In Brazil, there is not any special orientation for the protection of those occupational persons, nor a specific legislation. The purpose of this work is to evaluate the air kerma rate at critical anatomic regions of the occupationally exposed staff that carry out IC procedures, in representative incidences in order to give subsidies for individual monitoring procedures implementation and to give more information about their radiation protection. The air kerma rate has been measured in the often used condition in the two more common IC procedures namely angiography and coronary angioplasty, using an adult patient simulator irradiated under RAO, LAO and AP projections for fluoro and digital acquisition modes. The measurements have been made in 45 points around the examination table at 5 different representatives heights of: eyes lens, thorax, hands, gonads and knees. AP projection shows the smaller scattered radiation contributions and a more homogeneous exposure distribution. The digital acquisition mode gives air kerma rates about 4 times higher than fluoro mode for LAO projection in the position occupied by the interventionist doctor, the anesthetist and the nursing staff. The most critical anatomic regions are: knees and gonads (without protection). On the physician hands position, values as high as 5 mGy/h have been measured, which can overpass, depending on the number of procedures done, the individual occupational annual limit. Therefore, in IC it is necessary to implement additional protection tools, elaborate safety guides (based on international experiences

    OBJECTIVES The aim of this study was to investigate gender-based differences in nuclear cardiology practice, globally, with particular focus on laboratory volume, radiation dose, protocols, and best practices. BACKGROUND It is unclear if gender-based differences exist in radiation exposure for nuclear cardiology procedures. METHODS In a large multicenter observational cross-sectional study encompassing 7911 patients in 65 countries, radiation effective dose was estimated for each examination. Patient-level best practices relating to radiation exposure were compared between genders. Analysis of covariance was utilized to determine any difference in radiation exposure according to gender, region, and the interaction between gender and region. Linear, logistic, and hierarchical regression models were developed to evaluate gender-based differences in radiation exposure and laboratory adherence to best practices. We also included the United Nations’ gender inequality and human development indices as covariates in multivariable models. RESULTS The proportion of MPI studies performed in women varied between countries, however there was no significant correlation with gender inequality index. Globally, mean effective dose for nuclear cardiology procedures was only slightly lower in women (9.6±4.5 mSv) than in men (10.3±4.5 mSv men, pnuclear cardiology procedures, only small differences were observed between genders worldwide. Regional variations noted in MPI use and radiation dose offer potential opportunities to address gender-related differences in delivery of nuclear cardiology care. PMID:27056156

    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.

    AIM: The aim of this study was to describe the contribution of mammographic and sonographic findings to the discrimination of typical and atypical histopathologic groups of medullary carcinomas of the breast. MATERIALS AND METHODS: Imaging findings were retrospectively assessed in 33 women with medullary carcinomas (15 typical medullary carcinomas and 18 atypical medullary carcinomas) identified during pre-operative mammography. Twenty-nine of these women also had ultrasound and these findings were reviewed. RESULTS: Mammography showed a well circumscribed mass in 10 of the 15 (67%) typical medullary carcinomas and in four of the 17 (24%) atypical medullary carcinomas (P < 0.02). One small tumour in a woman with atypical medullary carcinoma was missed on mammography and was shown only on sonography. Sonographically, an irregular margin surrounding the whole mass or part of it was seen in three out of 14 (21%) patients with typical medullary carcinoma and in nine out of 15 (60%) patients with atypical medullary carcinomas (P < 0.05). Posterior acoustic shadowing was more often observed in the typical medullary carcinoma group than in atypical medullary carcinoma and the difference was found to be statistically significant (P < 0.05). None of the other mammographic and sonographic findings were sufficiently characteristic to allow for a differentiation between two groups. CONCLUSION: When typical medullary carcinomas were compared with atypical medullary carcinomas according to imaging features, they tended to be well circumscribed masses on both mammography and sonography, and a posterior acoustic shadow was not found on sonography. However, the imaging findings in these two subgroups often resembled each other and histopathology will always be required to confirm the diagnosis. Yilmaz, E. et al. (2002)

    Comparison of Latin American (LA) nuclear cardiology (NC) practice with that in the rest of the world (RoW) will identify areas for improvement and lead to educational activities to reduce radiation exposure from NC. INCAPS collected data on all SPECT and PET procedures performed during a single week in March-April 2013 in 36 laboratories in 10 LA countries (n = 1139), and 272 laboratories in 55 countries in RoW (n = 6772). Eight "best practices" were identified a priori and a radiation-related Quality Index (QI) was devised indicating the number used. Mean radiation effective dose (ED) in LA was higher than in RoW (11.8 vs 9.1 mSv, p < 0.001). Within a populous country like Brazil, a wide variation in laboratory mean ED was found, ranging from 8.4 to 17.8 mSv. Only 11% of LA laboratories achieved median ED <9 mSv, compared to 32% in RoW (p < 0.001). QIs ranged from 2 in a laboratory in Mexico to 7 in a laboratory in Cuba. Three major opportunities to reduce ED for LA patients were identified: (1) more laboratories could implement stress-only imaging, (2) camera-based methods of ED reduction, including prone imaging, could be more frequently used, and (3) injected activity of 99m Tc could be adjusted reflecting patient weight/habitus. On average, radiation dose from NC is higher in LA compared to RoW, with median laboratory ED <9 mSv achieved only one third as frequently as in RoW. Opportunities to reduce radiation exposure in LA have been identified and guideline-based recommendations made to optimize protocols and adhere to the "as low as reasonably achievable" (ALARA) principle.

    Celiac disease is a common non-communicable disease with varied presentations. Purpose of this study was to find the duodeno-endoscopic features in celiac disease and to compare duodeno-endoscopic and histological findings between typical and atypical celiac disease in children. Hospital based observational study was conducted at Sir Padampat Mother and Child Health Institute, Jaipur from June 2015 to May 2016. Patients were selected and divided in two groups- typical and atypical celiac disease based upon the presenting symptoms. Upper gastrointestinal endoscopy and duodenal biopsy was performed for serology positive patients. Results were analysed using appropriate statistical test of significance. Out of 101 enrolled patients, 47.5% were male. Age ranged from 1 to 18 years. Study showed that 54.5% were typical and 45.5% were atypical. Patients presenting with atypical symptoms were predominantly of older age group. On endoscopy, scalloping, mosaic pattern, reduced fold height and absent fold height; and in histology, advanced Marsh stage were significantly higher in the typical group. Awareness of atypical presentations as well as duodeno-endoscopic features may have considerable practical importance for the diagnosis of celiac disease in children. Scalloping, mosaic pattern, reduced fold height and nodularity are main endoscopic markers of celiac disease in children. Endoscopic markers of duodenal mucosa may be important in early diagnosis of celiac disease, in children subjected to endoscopy for atypical presentations or indication other than suspected celiac disease.

    Objective: To investigate the non-typical MRI findings of the branchial cleft cysts in order to improve their diagnoses. Methods: 10 cases with branchial cleft cysts proven by surgery and pathology were collected and their MRI features were analyzed. There were 6 male and 4 female, aged 15 to 70, with an averaged age of 37. All patients underwent plain MR scan, 6 patients underwent enhanced scan, and 4 patients underwent magnetic resonance angiography. Results: All 10 cases were second branchial cleft cysts, including 4 of Bailey type I and 6 of type II. The non-typical MRI findings were composed of haematocele (2 cases), extraordinarily thick cyst wall (4 cases), solidified cystic fluid (2 cases), and concomitant canceration (2 cases), which made the diagnoses more difficult. Conclusion: The diagnoses of the branchial cleft cysts with non-typical MRI features should combined with its characteristic of position that located at the lateral portion of the neck adjacent to the anterior border of the sternocleidomastoid muscle at the mandibular angle. The findings, such as thickened wall, ill-defined margin, and vascular involvement or jugular lymphadenectasis, strongly suggest cancerous tendency. (authors)

    In order to investigate the brain morphological differences between typical schizophrenia and atypical psychosis, the brain CTs of 41 patients with typical schizophrenia, 27 patients with atypical psychosis (ATP), and 20 controls were examined. The schizophrenics had larger values for 9 CT indices, i.e., interhemispheric fissure (IHF) index, VBR, 2 lateral ventricles (L-V) and 3rd venricle (III-V) indices, and 4 sylvian fissure (SF) indices, while the values of ATP patients for 3 SF indices were greater than for the controls. Moreover, the schizophrenics had greater III-V and L-V indices than the ATP patients. The correlation matrix of CT indices indicates that the III-V index correlated well with the other CT indices, whereas the VBR, IHF and right SF indices did not. Therefore, it was speculated that there might be 3 subgroups, each of which has a main focus of alteration in the above-mentioned regions. Therefore, all the cases were divided by means of a cluster analysis into 5 groups. Group I, which contained mainly normal controls, and Group II, which consisted mainly of atypical psychosis patients, had no abnormal CT findings. Group III, which comprised mainly ATP pateints and paranoid type schizophrenics, had right SF enlargement. Group IV, which showed significant IHF enlargement, and the residue group, which had larger VBR and significant left SF enlargement, consisted mostly of schizophrenics. Thus, our results suggest that the classification by CT data corresponds on the whole to our clinical diagnosis, according to which schizophrenic psychosis is divided into typical schizophrenia and atypical psychosis, and that each of the two psychosis groups may be further classified into distinct subgroups.

    ABSTRACT Background Identifying PD‐specific biomarkers in biofluids will greatly aid in diagnosis, monitoring progression, and therapeutic interventions. PD biomarkers have been limited by poor discriminatory power, partly driven by heterogeneity of the disease, variability of collection protocols, and focus on de novo, unmedicated patients. Thus, a platform for biomarker discovery and validation in well‐characterized, clinically typical, moderate to advanced PD cohorts is critically needed. Methods BioFIND (Fox Investigation for New Discovery of Biomarkers in Parkinson's Disease) is a cross‐sectional, multicenter biomarker study that established a repository of clinical data, blood, DNA, RNA, CSF, saliva, and urine samples from 118 moderate to advanced PD and 88 healthy control subjects. Inclusion criteria were designed to maximize diagnostic specificity by selecting participants with clinically typical PD symptoms, and clinical data and biospecimen collection utilized standardized procedures to minimize variability across sites. Results We present the study methodology and data on the cohort's clinical characteristics. Motor scores and biospecimen samples including plasma are available for practically defined off and on states and thus enable testing the effects of PD medications on biomarkers. Other biospecimens are available from off state PD assessments and from controls. Conclusion Our cohort provides a valuable resource for biomarker discovery and validation in PD. Clinical data and biospecimens, available through The Michael J. Fox Foundation for Parkinson's Research and the National Institute of Neurological Disorders and Stroke, can serve as a platform for discovering biomarkers in clinically typical PD and comparisons across PD's broad and heterogeneous spectrum. © 2016 The Authors.

    The birth of nuclear cardiology has generally been attributed to a 1927 experiment during which a radium salt was injected in one arm vein and the circulation time calculated by recording the arrival of the radioactivity in the opposite arm. This simple experiment lead to the radiocardiogram in the late 1940s that was used to measure left ventricular function and, later, cardiac output. This chapter provides a brief overview of nuclear cardiology. Methodology is presented when it is important for the understanding of test results. The use of these studies in the diagnosis and evaluation of patients with suspected cardiovascular disease is emphasized

    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- 99 m-M I B I

    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.

    Objective: To study radiographic features of atypical adenomatous hyperplasia (AAH) of lung and correlate them with their pathologic findings, so as to improve the imaging diagnose. Methods: The imaging features of 8 patients with pathology- proved AAH were reviewed. All patients were women with age ranging from 35 to 74 years. All cases had chest radiography and HRCT. The radiographic findings were studied retrospectively and correlated with those of pat hology. Results: On chest X-ray, the foci in five patients presented as nodule-like area of a bit high attenuation, while the chest radiograph in the other three patients were negative. On HRCT, all 8 patients presented as non-solid nodules. All lesions were round or oval shaped with well-defined margin (n=4) or poor-defined margin (n=3). The greatest dimension of the lesions ranged from 5.0 mm to 20.0 mm. Their CT value ranged from -362.7 HU to -485.6 HU, the mean CT value was (-423.0 ± 47.0) HU. Air bronchograms and/or bubbles were seen in 5 lesions. Coarse spiculation and pleural tag was not seen in any lesion. Before operation, all the nodules did not change in size over a follow-up period from one month to six months. Pathologic findings showed atypical epithelial cell proliferation along thickened alveolar septa without alveolar collapse. Conclusion: AAH should be considered in cases with the following features: (1) nodules ate found in lung cancer screening or incidentally detected; (2) the diameter of the nodule is usually less than 10 mm; (3) the lesion presented as non-solid nodule on HRCT, air bronchogram and/or bubble sign can be seen; (4) no coarse spiculation and plural tag was seen.

    The vast variability of the overall rare congenital anomalies of the inferior vena cava (IVC) are mostly detected by accident through different imaging modalities. These cannot be classed as pathological findings, and should not be confused with lymphomas and has to differ from secondary collateral venous pathways. Based on 656 CT examinations 10.5% known forms of IVC anomalies were found. According to the embryological development three main groups of IVC variants could be nosologically classified: agenesis of the suprarenal IVC, anomalies of the pars renalis and anomalies of the infrarenal IVC. Additionally three unusual anomaly complexes were found. For the understanding details of the embryology based on a simplified depiction are presented. (orig.) [de

    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.)

    Full Text Available In the year 2014, there were certain remarkable trials that have changed the practice of cardiology and beyond that these tried to explained some long awaited unanswered questions. Like SIMPLICITY HTN-3 trial clearly explained the uselessness of renal denervation therapy in systemic hypertension. PARADIGM-HF trial provided positive data that may be useful to enrich the basket of medical treatment with a new drug LCZ 696 after a long time. Another important meta-analysis in heart failure questioned the status of beta blockers as standard therapy to improve prognosis in patients with concomitant heart failure and atrial fibrillation . In myocardial infraction , CvLPRIT trial supported the concept of complete revascularization at the time of primary PCI and TASTE trials failed to show expected benefit of thrombus aspiration in acute MI. FFR got more strength from FAME 2 trial. Another important question that was addressed in SECURITY trial was optimal duration of DAPT after second generation DES implantation. One year follow-up results of ABSORB II suggested that bioresorbable scaffolds are currently facing problem of stent thrombosis that might be taken care in near future with improvement in strut technology. Successful use of "Heart in a box" machine provided a major thrust for cardiac transplantation. SEARCH-AF evaluated the efficacy of a novel mobile health technology in the real world to screen for atrial fibrillation (now called as life style disease. A Meta-analysis provided a more comprehensive picture of the new oral anticoagulants as a therapeutic option in atrial fibrillation. Positive results for trans catheter pm-VSD closure in paediatric population were also demonstrated by a randomized controlled trial. Role of corticosteroids in tubercular pericarditis also got the answer in a trial published in 2014.

    Cardiovascular disease in reptiles generally is considered an uncommon finding in captive animals, but no large-scale, cross-sectional studies have been performed to determine its prevalence. It is possible that cardiovascular disease is more common than is generally accepted and that the current belief results from limited clinical and diagnostic experience. This article offers guidance drawn from the author's clinical experience and the available literature. It is important that veterinarians pursue a thorough history, physical examination, and diagnostic work-up when managing cardiovascular disease in a reptile case. Veterinarians working with these cases should document their findings and share them with their colleagues to build an evidence-based foundation for reptile medicine.

    US government-funded early home visiting services are expanding significantly. The most widely implemented home visiting models target at-risk new mothers and their infants. Such home visiting programs typically aim to support infant-parent relationships; yet, such programs' effects on infant attachment quality per se are as yet untested. Given these programs' aims, and the crucial role of early attachments in human development, it is important to understand attachment processes in home visited families. The current, preliminary study examined 94 high-risk mother-infant dyads participating in a randomized evaluation of the Healthy Families Durham (HFD) home visiting program. We tested (a) infant attachment security and disorganization as predictors of toddler behavior problems and (b) program effects on attachment security and disorganization. We found that (a) infant attachment disorganization (but not security) predicted toddler behavior problems and (b) participation in HFD did not significantly affect infant attachment security or disorganization. Findings are discussed in terms of the potential for attachment-specific interventions to enhance the typical array of home visiting services.

    Full Text Available Neonicotinoid insecticides are nicotinic acetylcholine receptor agonists used worldwide. Their environmental health effects including neurotoxicity are of concern. We previously determined a metabolite of acetamiprid, N-desmethyl-acetamiprid in the urine of a patient, who exhibited some typical symptoms including neurological findings. We sought to investigate the association between urinary N-desmethyl-acetamiprid and the symptoms by a prevalence case-control study. Spot urine samples were collected from 35 symptomatic patients of unknown origin and 50 non-symptomatic volunteers (non-symptomatic group, NSG, 4-87 year-old. Patients with recent memory loss, finger tremor, and more than five of six symptoms (headache, general fatigue, palpitation/chest pain, abdominal pain, muscle pain/weakness/spasm, and cough were in the typical symptomatic group (TSG, n = 19, 5-69 year-old; the rest were in the atypical symptomatic group (ASG, n = 16, 5-78 year-old. N-desmethyl-acetamiprid and six neonicotinoids in the urine were quantified by liquid chromatography-tandem mass spectrometry. The detection of N-desmethyl-acetamiprid was the most frequent and highest in TSG (47.4%, 6.0 ppb (frequency, maximum, followed by in ASG (12.5%, 4.4 ppb and in NSG (6.0%, 2.2 ppb, however acetamiprid was not detected. Thiamethoxam was detected in TSG (31.6%, 1.4 ppb, in ASG (6.3%, 1.9 ppb, but not in NSG. Nitenpyram was detected in TSG (10.5%, 1.2 ppb, in ASG (6.3%, not quantified and in NSG (2.0%, not quantified. Clothianidin was only detected in ASG (6.3%, not quantified, and in NSG (2.0%, 1.6 ppb. Thiacloprid was detected in ASG (6.3%, 0.1 ppb. The cases in TSG with detection of N-desmethyl-acetamiprid and thiamethoxam were aged 5 to 62 years and 13 to 62 years, respectively. Detection of N-desmethyl-acetamiprid was associated with increased prevalence of the symptoms (odds ratio: 14, 95% confidence interval: 3.5-57. Urinary N-desmethyl-acetamiprid can be used as a

    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

    Artificial intelligence and machine learning are poised to influence nearly every aspect of the human condition, and cardiology is not an exception to this trend. This paper provides a guide for clinicians on relevant aspects of artificial intelligence and machine learning, reviews selected applications of these methods in cardiology to date, and identifies how cardiovascular medicine could incorporate artificial intelligence in the future. In particular, the paper first reviews predictive modeling concepts relevant to cardiology such as feature selection and frequent pitfalls such as improper dichotomization. Second, it discusses common algorithms used in supervised learning and reviews selected applications in cardiology and related disciplines. Third, it describes the advent of deep learning and related methods collectively called unsupervised learning, provides contextual examples both in general medicine and in cardiovascular medicine, and then explains how these methods could be applied to enable precision cardiology and improve patient outcomes.

    The evaluation of dose to physicians involved in Interventional Cardiology (IC) is an extreme important matter due to the high and non-uniform distribution of dose values. The radiation control during each procedure is complex and the reasons for the high exposures have many different causes. Many international recommendations have already been written aiming the radiation protection optimization in IC. In Brazil, there is not any special orientation for the protection of those occupational persons, nor a specific legislation. The purpose of this work is to evaluate the air kerma rate at critical anatomic regions of the occupationally exposed staff that carry out IC procedures, in representative incidences in order to give subsidies for individual monitoring procedures implementation and to give more information about their radiation protection. The air kerma rate has been measured in the often used condition in the two more common IC procedures namely angiography and coronary angioplasty, using an adult patient simulator irradiated under RAO, LAO and AP projections for fluoro and digital acquisition modes. The measurements have been made in 45 points around the examination table at 5 different representatives heights of: eyes lens, thorax, hands, gonads and knees. AP projection shows the smaller scattered radiation contributions and a more homogeneous exposure distribution. The digital acquisition mode gives air kerma rates about 4 times higher than fluoro mode for LAO projection in the position occupied by the interventionist doctor, the anesthetist and the nursing staff. The most critical anatomic regions are: knees and gonads (without protection). On the physician hands position, values as high as 5 mGy/h have been measured, which can overpass, depending on the number of procedures done, the individual occupational annual limit. Therefore, in IC it is necessary to implement additional protection tools, elaborate safety guides (based on international experiences

    Decision-making is complex in modern medicine and should ideally be based on available data, structured knowledge and proper interpretation in the context of an individual patient. Automated algorithms, also termed artificial intelligence that are able to extract meaningful patterns from data collections and build decisions upon identified patterns may be useful assistants in clinical decision-making processes. In this article, artificial intelligence-based studies in clinical cardiology are reviewed. The text also touches on the ethical issues and speculates on the future roles of automated algorithms versus clinicians in cardiology and medicine in general.

    The present review provides a selected choice of clinical trials and therapeutic advances in the field of cardiology in 2015. A new treatment option in heart failure will become available this year in Switzerland. In interventional cardiology, new trials have been published on the duration of dual antiplatelet therapy, the new stents with bioresorbable scaffold and the long-term results of TAVR in patients who are not surgical candidates or at high surgical risk. RegardingAF the BRIDGE trial provides new evidences to guide the management of patients during warfarin interruption for surgery. Recent publications are changing the paradigm of AF treatment by showing a major impact of the management of cardiometabolic risk factors. Finally, refined criteria for ECG interpretation in athletes have been recently proposed to reduce the burden of false-positive screening.

    Full Text Available Artificial intelligence (AI provides machines with the ability to learn and respond the way humans do and is also referred to as machine learning. The step to building an AI system is to provide the data to learn from so that it can map relations between inputs and outputs and set up parameters such as “weights”/decision boundaries to predict responses for inputs in the future. Then, the model is tested on a second data set. This article outlines the promise this analytic approach has in medicine and cardiology.

    Full text: Nuclear Cardiology has maintained a prominent position in the assessment of CAD and has become the end-point in Clinical Trials for the following reasons: Non-invasive assessment of CAD, Assessment of presence, localisation and severity, Widely available, feasible and reproducible, Visualisation of blood flow and pumping. The main areas of cardiology that are amenable to assessment with nuclear cardiology include: Stable and unstable CAD, Acute and post MI, Cardiomyopathy, Valvular disease and shunts, Cardiotoxicity, Aneurysms, Transplants The application of nuclear cardiology in these conditions will help in the management of patients by providing information relating to: Diagnosis and prognosis, Risk stratification, Medical Vs surgical treatment, Haemodynamic significance, Efficiency of management The main application in practical terms is in the assessment of CAD at variable stages: Before, during and after an incident: Before Incident: -Enhancing diagnosis and prognosis in patients with CAD, Providing functional data for changes on angiography. During Incident: -Assessing criteria for admission and further tests. After Incident: -Identifying hibernating myocardium, - Risk stratification. Risk Stratification highlights the outcome following nonfatal MI as the patients may be split into 2 categories: Low-risk group -Comprise 50-66% of patients, -Can be managed with medical treatment High-risk group, -Comprise (34-50%), -Prone to future complications within 3 months (Death, reinfarction, CCF and unstable angina). Viability: Is a spectrum of overlapping clinical states following an incident.

    Nuclear cardiology has been an exciting new field of nuclear medicine. Few examples of the dynamism and excitement of nuclear medicine demonstrate this field's vitality in the way that nuclear cardiology does. Recent new developments in radiopharmaceuticals and instrumentation have established this field as an extremely useful clinical tool and provide a new dimension to the evaluation of a cardiac patient, more so being nonivasive in nature. An attempt has been made to focus the attention on some of the recent advances in nuclear cardiology with a special reference to its clinical application in the field of cardiology. Nuclear cardiology is the most important field of nuclear medicine which has shown most promising results and has opened a new horizon in the field of diagnostic noninvasive cardiac technique. Now it has come of age in concept, instrument development and clinical application. It is very rapidly growing into a subspeciality. (author)

    Let a pure state | ψ> be chosen randomly in an NM-dimensional Hilbert space, and consider the reduced density matrix ρ A of an N-dimensional subsystem. The bipartite entanglement properties of | ψ> are encoded in the spectrum of ρ A . By means of a saddle point method and using a "Coulomb gas" model for the eigenvalues, we obtain the typical spectrum of reduced density matrices. We consider the cases of an unbiased ensemble of pure states and of a fixed value of the purity. We finally obtain the eigenvalue distribution by using a statistical mechanics approach based on the introduction of a partition function.

    Dodson, John A; Matlock, Daniel D; Forman, Daniel E

    2016-09-01

    Given changing demographics, patients with cardiovascular (CV) disease in developed countries are now older and more complex than even a decade ago. This trend is expected to continue into the foreseeable future; accordingly, cardiologists are encountering patients with a greater number of comorbid illnesses as well as "geriatric conditions," such as cognitive impairment and frailty, which complicate management and influence outcomes. Simultaneously, technological advances have widened the therapeutic options available for patients, including those with the most advanced CV disease. In the setting of these changes, geriatric cardiology has recently emerged as a discipline that aims to adapt principles from geriatric medicine to everyday cardiology practice. Accordingly, the tasks of a "geriatric cardiologist" may include both traditional evidence-based CV management plus comprehensive geriatric assessment, medication reduction, team-based coordination of care, and explicit incorporation of patient goals into management. Given that the field is still in its relative infancy, the training pathways and structure of clinical programs in geriatric cardiology are still being delineated. In this review, we highlight the rationale behind geriatric cardiology as a discipline, several current approaches by geriatric cardiology programs, and future directions for the field.

    Unlike other techniques, nuclear cardiologic imaging enables evaluation of cardiac function employing radioactive tracers. This procedure can be used to assess myocardial blood flow, metabolism, viability, cardiac innervation and receptor status. Therefore, this noninvasive imaging modality can be regarded as supplementary to the screening methods in cardiology and also to angiography. General clinical use was not possible until the rapid development of nuclear medicine in the fifties began. With increasing wide-spread of positron emission tomography more detailed information on metabolic tissue characterization can be expected and will be of enormous relevance in clinical decision making and in selecting patients for interventions.

    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

    Cardiovascular diseases are the deadliest diseases worldwide, with 17.3 million deaths in 2008 alone. Among them, heart-related deaths are of the utmost relevance; a fact easily proven by the 7.25 million deaths caused by ischemic heart disease alone in that year. The latest advances in smartphones and mHealth have been used in the creation of thousands of medical apps related to cardiology, which can help to reduce these mortality rates. The aim of this paper is to study the literature on mobile systems and applications currently available, as well as the existing apps related to cardiology from the leading app stores and to then classify the results to see what is available and what is missing, focusing particularly on commercial apps. Two reviews have been developed. One is a literature review of mobile systems and applications, retrieved from several databases and systems such as Scopus, PubMed, IEEE Xplore, and Web of Knowledge. The other is a review of mobile apps in the leading app stores, Google play for Android and Apple's App Store for iOS. Search queries up to May 2013 located 406 papers and 710 apps related to cardiology and heart disease. The most researched section in the literature associated with cardiology is related to mobile heart (and vital signs) monitoring systems and the methods involved in the classification of heart signs in order to detect abnormal functions. Other systems with a significant number of papers are mobile cardiac rehabilitation systems, blood pressure measurement, and systems for the detection of heart failure. The majority of apps for cardiology are heart monitors and medical calculators. Other categories with a high number of apps are those for ECG education and interpretation, cardiology news and journals, blood pressure tracking, heart rate monitoring using an external device, and CPR instruction. There are very few guides on cardiac rehabilitation and apps for the management of the cardiac condition, and there were no

    The findings of many new cardiology clinical trials over the last year have been published or presented at major international meetings. This paper aims to describe and place in context a summary of the key clinical trials in cardiology presented between January and December 2016. The authors reviewed clinical trials presented at major cardiology conferences during 2016 including the American College of Cardiology (ACC), European Association for Percutaneous Cardiovascular Interventions (EuroPCR), European Society of Cardiology (ESC), European Association for the Study of Diabetes (EASD), Transcatheter Cardiovascular Therapeutics (TCT), and the American Heart Association (AHA). Selection criteria were trials with a broad relevance to the cardiology community and those with potential to change current practice. A total of 57 key cardiology clinical trials were identified for inclusion. Here we describe and place in clinical context the key findings of new data relating to interventional and structural cardiology including delayed stenting following primary angioplasty, contrast-induced nephropathy, management of jailed wires, optimal duration of dual antiplatelet therapy (DAPT), stenting vs bypass for left main disease, new generation stents (BioFreedom, Orsiro, Absorb), transcatheter aortic valve implantation (Edwards Sapien XT, transcatheter embolic protection), and closure devices (Watchman, Amplatzer). New preventative cardiology data include trials of bariatric surgery, empagliflozin, liraglutide, semaglutide, PCSK9 inhibitors (evolocumab and alirocumab), and inclisiran. Antiplatelet therapy trials include platelet function monitoring and ticagrelor vs clopidogrel for peripheral vascular disease. New data are also presented in fields of heart failure (sacubitril/valsartan, aliskiren, spironolactone), atrial fibrillation (rivaroxaban in patients undergoing coronary intervention, edoxaban in DC cardioversion), cardiac devices (implantable cardioverter

    The rigorous cardiovascular (CV) demands of sport, combined with training-related cardiac adaptations, render the athlete a truly unique CV patient and sports cardiology a truly unique discipline. Cardiologists are advised to adopt a systematic approach to the CV evaluation of athletes, taking into consideration the individual sports culture, sports-specific CV demands, CV adaptations and their appearance on cardiac testing, any existing or potential interaction of the heart with the internal and external sports environment, short- and long-term CV risks, and potential effect of performance-enhancing agents and antidoping regulations. This article outlines the systematic approach, provides a detailed example, and outlines contemporary sports cardiology core competencies. Copyright © 2015 Elsevier Inc. All rights reserved.

    Interventional radiology has seen rapid growth in cardiology and represents an alternative to hazardous surgery. Recently there has been a substantial growth in the number of procedures being performed and interventional cardiology (IC) procedures are the most common interventional procedures in Europe. Advances in imaging technology have facilitated the development of increasingly complex radiological IC equipment. Currently, the technology is developing at a rate ahead of supporting research, equipment standards and a regulatory framework. International standards play a key role in the design, manufacture and performance of radiological IC equipment. A survey of 12 IC systems (15 imaging chains) was conducted in Irish hospitals. The aim of the study was to assess the imbalance between rapidly advancing technology and existing standards and to propose recommendations for new IC equipment standards. The results demonstrate the need for definitive equipment requirements and standardisation in the design, manufacture, acceptance and maintenance of IC equipment. (authors)

    This study sought to examine the prevalence of mitral stenosis (MS) and its impact on in-hospital and 1-year clinical outcomes among patients undergoing transcatheter aortic valve replacement (TAVR). Patients with coexisting severe aortic stenosis and MS are increasingly being considered for TAVR. The study cohort included 44,755 patients (age ≥18 years) who underwent TAVR during November 1, 2011, to September 30, 2015, and were registered in Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapies (TVT) Registry. One-year outcomes were assessed by linking TVT registry data of this cohort to patient-specific Centers for Medicare & Medicaid Services administrative claims data (n = 31,453). The primary outcome was the composite of death, stroke, heart failure-related hospitalization, and mitral valve intervention at 1 year. MS was present in 11.6% of cohort (mean age, 82 years; 52% males), being severe in 2.7%. Severe MS was associated with higher in-hospital mortality rates (5.6% vs. 3.9% for nonsevere MS and 4.1% for no MS; p = 0.02). In contrast to those without MS, severe MS group had significantly higher risk for the primary outcome, mortality (1 year), and heart failure-related hospitalization (1 year) (adjusted hazard ratio: 1.2 [95% confidence interval (CI): 1.1 to 1.4], 1.2 [95% CI: 1.0 to 1.4], and 1.3 [95% CI: 1.1 to 1.5], respectively; p < 0.05 for all). Approximately one-tenth of patients undergoing TAVR have concomitant MS. Severe MS is an independent predictor of 1-year adverse clinical outcomes following TAVR. The higher risk for long-term adverse events must be considered when evaluating patients with combined aortic stenosis and MS for TAVR. Copyright © 2018 American College of Cardiology Foundation.

    Cardiology fellows can be exposed to high radiation levels during procedures. Proper radiation training and implementation of safety procedures is of critical importance in lowering physician health risks associated with radiation exposure. Participants were cardiology fellows in the United States (n = 2,545) who were contacted by e-mail to complete an anonymous survey regarding the knowledge and practice of radiation protection during catheterization laboratory procedures. An on-line survey engine, SurveyMonkey, was used to distribute and collect the results of the 10-question survey. The response rate was 10.5%. Of the 267 respondents, 82% had undergone formal radiation safety training. Only 58% of the fellows were aware of their hospital's pregnancy radiation policy and 60% knew how to contact the hospital's radiation safety officer. Although 52% of the fellows always wore a dosimeter, 81% did not know their level of radiation exposure in the previous year and only 74% of fellows knew the safe levels of radiation exposure. The fellows who had received formal training were more likely to be aware of their pregnancy policy, to know the contact information of their radiation safety officer, to be aware of the safe levels of radiation exposure, to use dosimeters and RadPad consistently, and to know their own level of radiation exposure in the previous year. In conclusion, cardiology fellows have not been adequately educated about radiation safety. A concerted effort directed at physician safety in the workplace from the regulatory committees overseeing cardiology fellowships should be encouraged. Published by Elsevier Inc.

    2017-08-01

    Introduction Paediatricians with Expertise in Cardiology assess children with a full history, examination, and often perform an echocardiogram. A minority are then referred to an outreach clinic run jointly with a visiting paediatric cardiologist. The accuracy of the echocardiography diagnosis made by the Paediatrician with Expertise in Cardiology is unknown. Materials and methods We conducted a retrospective review of clinic letters for children seen in the outreach clinic for the first time between March, 2004 and March, 2011. Children with CHD diagnosed antenatally or elsewhere were excluded. We recorded the echocardiography diagnosis made by the paediatric cardiologist and previously by the Paediatrician with Expertise in Cardiology. The Paediatrician with Expertise in Cardiology referred 317/3145 (10%) children seen in the local cardiac clinics to the outreach clinic over this period, and among them 296 were eligible for inclusion. Their median age was 1.5 years (range 1 month-15.1 years). For 244 (82%) children, there was complete diagnostic agreement between the Paediatrician with Expertise in Cardiology and the paediatric cardiologist. For 29 (10%) children, the main diagnosis was identical with additional findings made by the paediatric cardiologist. The abnormality had resolved in 17 (6%) cases by the time of clinic attendance. In six (2%) patients, the paediatric cardiologist made a different diagnosis. In total, 138 (47%) patients underwent a surgical or catheter intervention. Discussion Paediatricians with Expertise in Cardiology can make accurate diagnoses of CHD in children referred to their clinics. This can allow effective triage of children attending the outreach clinic, making best use of limited specialist resources.

    Full Text Available In India, the discipline of cardiology started in the late 1950s and at that time pediatric cardiology was practiced as a part of cardiology specialty. This article traces the history of pediatric cardiology in India. Dr. S. Padmawati and Dr. Kamala Vytilingam underwent training in pediatric cardiology at international centers in the early 1950s and early 1960s. Dr. N. Gopinath successfully closed a ventricular septal defect using a pump oxygenator at Christian Medical College, Vellore. Open heart surgery program kicked off in the 1960s with the tireless efforts of many other surgeons. Dr. Rajendra Tandon, trained for 2 years at Boston Children Hospital under Dr. Alexander Nadas, joined the Department of Cardiology at the All India Institute of Medical Sciences, New Delhi in 1963. This and many other stories are described.

    Big Data promises to change cardiology through a massive increase in the data gathered and analysed; but its impact goes beyond improving incrementally existing methods. The potential of comprehensive data sets for scientific discovery is examined, and its impact on the scientific method generally and cardiology in particular is posited, together with likely consequences for research and practice. Big Data in cardiology changes how new insights are being discovered. For it to flourish, significant modifications in the methods, structures, and institutions of the profession are necessary.

Both nuclear cardiology and other cardiac imaging have its own advantage and disadvantage in the diagnostic of coronary artery disease. And the relationship of them is complementary but not instead of each other. Nuclear cardiology provides a one-stop shop for diagnosis, risk stratification, and management of coronary artery disease. Nuclear cardiology plays a very important role in the diagnostic of coronary artery disease in early stage in the special group of people. (authors)

    The development of fatty acids labelled with iodine-123 is reviewed. The variety of methods for producing 123 I and introducing radioiodine into the molecule is discussed and the important points of the biochemical background are recalled with the aim of finding a broad application for 123 I-labelled fatty acids. The results of the pharmacokinetic studies and biochemical analysis are presented as they prove that both 17- 123 I-heptadecanoic acid (IHA) and 15-(rho- 123 I-phenyl)pentadecanoic acid (IPPA) exhibit analogous behaviour to that of the naturally occurring fatty acids. Clinical applications demonstrated two fields of importance: (i) applications solely for imaging the heart and (ii) assessment of myocardial turnover rates of fatty acids for functional diagnosis. Moreover, very recent studies show that the provision of information about prognosis of myocardial diseases and the applied cardiological therapy appear to be possible. (author)

    Boomerang dysplasia is a rare lethal osteochondrodysplasia characterized by disorganized mineralization of the skeleton, leading to complete nonossification of some limb bones and vertebral elements, and a boomerang-like aspect to some of the long tubular bones. Like many short-limbed skeletal dysplasias with accompanying thoracic hypoplasia, the potential lethality of the phenotype can be difficult to ascertain prenatally. We report a case of boomerang dysplasia prenatally diagnosed by use of ultrasonography and 3D-CT imaging, and identified a novel mutation in the gene encoding the cytoskeletal protein filamin B (FLNB) postmortem. Findings that aided the radiological diagnosis of this condition in utero included absent ossification of two out of three long bones in each limb and elements of the vertebrae and a boomerang-like shape to the ulnae. The identified mutation is the third described for this disorder and is predicted to lead to amino acid substitution in the actin-binding domain of the filamin B molecule. Copyright © 2012 S.

    Accurate cardiovascular imaging is essential for the successful management of patients with congenital heart disease (CHD). Echocardiography and angiography have been for long time the most important imaging modalities in pediatric cardiology, but nuclear medicine has contributed in many situations to the comprehension of physiological consequences of CHD, quantifying pulmonary blood flow symmetry or right-to-left shunting. In recent times, remarkable improvements in imaging equipments, particularly in multidetector computed tomography and magnetic resonance imaging, have led to the progressive integration of high resolution modalities in the clinical workup of children affected by CHD, reducing the role of diagnostic angiography. Technology has seen a parallel evolution in the field of nuclear medicine, with the advent of hybrid machines, as SPECT/CT and PET/CT scanners. Improved detectors, hugely increased computing power, and new reconstruction algorithms allow for a significant reduction of the injected dose, with a parallel relevant decrease in radiation exposure. Nuclear medicine retains its distinctive capability of exploring at the tissue level many functional aspects of CHD in a safe and reproducible way. The lack of invasiveness, the limited need for sedation, the low radiation burden, and the insensitivity to body habitus variations make nuclear medicine an ideal complement of echocardiography. This is particularly true during the follow-up of patients with CHD, whose increasing survival represent a great medical success and a challenge for the health system in the next decades. Metabolic imaging using 18 FDG PET/CT has expanded its role in the management of infection and inflammation in adult patients, particularly in cardiology. The same expansion is observed in pediatric cardiology, with an increasing rate of studies on the use of FDG PET for the evaluation of children with vasculitis, suspected valvular infection or infected prosthetic devices.

    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)

    2009-10-01

    Quality assurance in clinical studies aiming at approval of pharmaceutical products is submitted to strict rules, controls and auditing regulations. Comparative instruments to ensure quality in diagnostic and therapeutic procedures are not available in interventional cardiology, likewise in other fields of cardiovascular medicine. Quality assurance simply consists of "quality registers" with basic data not externally controlled. Based on the experiences of clinical studies and their long history of standardization it is assumed that these data may be severely flawed thus being inappropriate to set standards for diagnostic and therapeutic strategies. The precondition for quality assurance are quality data. In invasive coronary angiography and intervention medical indications, the decision making process interventional versus surgical revascularization, technical performance and after - care are essential aspects affecting quality of diagnostics and therapy. Quality data are externally controlled data. To collect quality data an appropriate infrastructure is a necessary precondition which is not existent. For an appropriate infrastructure investments have to be done both to build up as well as to sustain the necessary preconditions. As long as there are no infrastructure and no investments there will be no "quality data". There exist simply registers of data which are not proved to be a basis for significant assurance and enhancement in quality in interventional coronary cardiology.

    The worldwide spread of smartphones has radically changed the habits of human life, allowing a 24/7 connection with other people. These changes have involved also Medicine with smartphones being able to simplify the clinical practice of physicians. The development of new external devices that can be connected to smartphones has further increased their use with mobile phones converted in portable electrocardiogram or echocardiogram machines. This extraordinary technological improvement seems to be partly in conflict with the classical tools available for the cardiologist, such as the "old" stethoscope that in 2016 had its 200th anniversary. This article focuses on the smartphone as a new tool available for the physicians, describing the most important potential uses and reporting an analysis of pros and cons of the smart-cardiology.

    Few data exist on internal medicine trainees' selection of cardiology training, although this is important for meeting future cardiology workforce needs. To discover trainees' professional development preferences and perceptions of cardiology, and their relationship to trainees' career choice. We surveyed trainees to discover their professional development preferences and perceptions of cardiology and the influence of those perceptions and preferences on the trainees' career choices. Participants rated 38 professional development needs and 19 perceptions of cardiology. Data collection took place from February 2009, through January 2010. Data analysis was conducted from May 2017 to December 2017. Multivariable models were used to determine the association of demographics and survey responses with prospective career choice. A total of 4850 trainees were contacted, and 1123 trainees (of whom 625 [55.7%] were men) in 198 residency programs completed surveys (23.1% response; mean [SD] age, 29.4 [3.5] years). Principal component analysis of survey responses resulted in 8-factor and 6-factor models. Professional development preferences in descending order of significance were stable hours, family friendliness, female friendliness, the availability of positive role models, financial benefits, professional challenges, patient focus, and the opportunity to have a stimulating career. The top perceptions of cardiology in descending order of significance were adverse job conditions, interference with family life, and a lack of diversity. Women and future noncardiologists valued work-life balance more highly and had more negative perceptions of cardiology than men or future cardiologists, who emphasized the professional advantages available in cardiology. Professional development factors and cardiology perceptions were strongly associated with a decision to pursue or avoid a career in cardiology in both men and women.

    As interventional cardiology can induce high doses not only for patients but also for the personnel, the delimitation of regulated areas (or zoning) and workstation analysis (dosimetry) are very important in terms of radioprotection. This paper briefly recalls methods and tools for the different steps to perform zoning and workstation analysis. It outlines the peculiarities of interventional cardiology, presents methods and tools adapted to interventional cardiology, and then discusses the same issues but for workstation analysis. It also outlines specific problems which can be met, and their possible adapted solutions

    Innovations in interventional cardiology historically predate those in neuro-intervention. As such, studying trends in interventional cardiology can be useful in exploring avenues to optimise neuro-interventional techniques. One such cardiology innovation has been the steady conversion of arterial puncture sites from transfemoral access (TFA) to transradial access (TRA), a paradigm shift supported by safety benefits for patients. While neuro-intervention has unique anatomical challenges, the access itself is identical. As such, examining the extensive cardiology literature on the radial approach has the potential to offer valuable lessons for the neuro-interventionalist audience who may be unfamiliar with this body of work. Therefore, we present here a report, particularly for neuro-interventionalists, regarding the best practices for TRA by reviewing the relevant cardiology literature. We focused our review on the data most relevant to our audience, namely that surrounding the access itself. By reviewing the cardiology literature on metrics such as safety profiles, cost and patient satisfaction differences between TFA and TRA, as well as examining the technical nuances of the procedure and post-procedural care, we hope to give physicians treating complex cerebrovascular disease a broader data-driven understanding of TRA. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    During the last years, since short physical mean life radionuclides have started to be used, radionuclide scanning has been experienced with remarkable culmination. There are detector devices, which jointly with computation equipments, allow to obtain multiple images per second as properly rapid gammagraphic series, in order to obtain whole hemodynamic data or to generate functional images no representing an anatomical structure but reporting about cardiac dynamics at regional level. In these techniques, employed in Nuclear Cardiology, the following radionuclides and radiopharmaceuticals are used: radiolabeled albumin 99m Tc red blood cells, 113m In-transferrin, very short physical mean life radionuclides, such as 195m Au, 178 Ta, 191 Ir. In addition, 113 Xe for coronary flow measurements; radiolabeled microspheres and macroparticles for angiogammagraphy; 129 Cs, 43 K, 81 Rb, 82 Rb and 201 Ti, the most largerly used, for myocardial gammagraphy. It is pointed out that fatty acids are the newest, basically if are radioiodate, and some 99m Tc labeled long chain hydrocarbons. It is expressed that 99m Tc-Sn-pyrophosphate has been used for myocardial infarction. Working on the development of new radiopharmaceuticals, basically fatty acids and 99m Tc chelating agents, for the improvement of these techniques is carried out. (author)

    In the field of nuclear cardiology, 99mTc labeled myocardial perfusion agents such as MIBI, Tetrofosmin and Teboroxime, 111In-antimyosin for imaging of myocardial necrosis, 123I-betamethyl-iodophenylpentadecanoic acid (BMIPP) for imaging of myocardial fatty acid metabolism and 123I-metaiodobenzylguanidine (MIBG) for imaging of myocardial adrenergic function are introduced recently in Japan. Improved image quality and simultaneous evaluation of myocardial perfusion, function and wall motion can be obtained with use of 99mTc labeled myocardial perfusion agents. 111In-antimyosin enables specific imaging of myocardial necrosis which leads to the use for wide variety of heart diseases. Discrepancy of the myocardial perfusion and metabolism in case of stunned myocardium or cardiomyopathy can be evaluated by 123I-BMIPP in conjunction with perfusion agent. Recently wide variety of diseases which may have cardiac adrenergic abnormality are targeted for 123I-MIBG imaging. These new radiopharmaceuticals are expected to be powerful tool for evaluation of the pathophysiology including severity and prognosis and evaluation of the etiology of the various heart diseases.

    The RECALCAR project (Spanish acronym for Resources and Quality in Cardiology Units) uses 2 data sources: a survey of cardiology units and an analysis of the Minimum Basic Data set of all hospital discharges of the Spanish National Health System. From 2011 to 2014, there was marked stability in all indicators of the availability, utilization, and productivity of cardiology units. There was significant variability between units and between the health services of the autonomous communities. There was poor implementation of process management (only 14% of the units) and scarce development of health care networks (17%). Structured cardiology units tended to have better results, in terms of both quality and efficiency. No significant differences were found between the different types of unit in the mean length of stay (5.5±1.1 days) or the ratio between successive and first consultations (2:1). The mean discharge rate was 5/1000 inhabitants/y and the mean rate of initial consultations was 16±4/1000 inhabitants/y. No duty or on-call cardiologist was available in 30% of cardiology units with 24 or more beds; of these, no critical care beds were available in 45%. Our findings support the recommendation to regionalize cardiology care and to promote the development of cardiology unit networks. Copyright © 2017 Sociedad Española de Cardiología.

    Early-career academic cardiologists, who many believe are an important component of the future of cardiovascular care, face myriad challenges. The Early Career Section Academic Working Group of the American College of Cardiology, with senior leadership support, assessed the progress of this cohort from 2013 to 2016 with a global perspective. Data consisted of accessing National Heart, Lung, and Blood Institute public information, data from the American Heart Association and international organizations, and a membership-wide survey. Although the National Heart, Lung, and Blood Institute increased funding of career development grants, only a small number of early-career American College of Cardiology members have benefited as funding of the entire cohort has decreased. Personal motivation, institutional support, and collaborators continued to be positive influential factors. Surprisingly, mentoring ceased to correlate positively with obtaining external grants. The totality of findings suggests that the status of early-career academic cardiologists remains challenging; therefore, the authors recommend a set of attainable solutions.

    To evaluate the natural course of subcentimeter hypervascular nodules at high risk for developing into hepatocellular carcinomas (SHNHR) using serial magnetic resonance imaging (MRI) in patients with a history of hepatocellular carcinoma (HCC). An SHNHR was defined as a subcentimeter hypervascular nodule having typical imaging findings of HCC on gadoxetic acid-enhanced MRI and diffusion-weighted imaging. We included 39 patients with 46 SHNHRs (mean size ± standard deviation, 6.1 ± 1.6 mm; range, 3.2 - 9.0 mm). Overt HCC was defined as pathology proven HCC or a nodule larger than 1 cm with typical imaging findings of HCC. The cumulative rate and the independent predictive factors for progression to overt HCC were evaluated. The median follow-up period was 139 days (range, 64 - 392 days). The cumulative progression rate to overt HCC at 3, 6, 9, and 12 months was 13.9 %, 61.7 %, 83.2 %, and 89.9 %. The initial size of SHNHR was a significant predictor of progression to overt HCC, with an optimal cut-off value of 5.5 mm. The progression rate of SHNHR to overt HCC within 12 months was high (89.9 %) in patients with history of HCC. The initial size of SHNHR was an important predictor for progression to overt HCC.

    Treadmill test combined with myocardial perfusion scintigraphy (MPS) is a commonly used technique in the assessment of coronary artery disease. However there are a group of patients who may not be able to undergo treadmill tests. Patients with underlying conditions like neuromuscular disease, musculoskeletal disorder, heart failure and end-stage renal disease (ESRD) on renal dialysis would find it difficult to perform exercise on a treadmill or bicycle ergometer. These conditions prevent them from performing adequate exercise. Such patients would benefit from pharmacological stress procedures combined with MPS. Nuclear medicine departments use various pharmacological agents while performing stress tests on cardiac patients. The most commonly used pharmacological agents for cardiac stress are coronary vasodilators and catecholamines. In addition to these agents, adjuvant use of nitrates and atropine is also a common practice in nuclear cardiology. This review addresses various physiological and pharmacological properties of the commonly used pharmacological stress agents in MPS and critically analyses their advantages and disadvantages, as well as their safety and efficacy.

    The cardiology and field of cardiovascular approaches are often mentioned as of the earliest concerns throughout the history of mankind civilization. During the golden ages of Islamic era, 9th to 12th centuries A.D., medical knowledge from various fields including cardiology was flourished by prominent Persian physicians and scholars. Among those outstanding physicians and scientists of the Islamic golden era, Avicenna is known as a famous and pioneer character. To outline the cardiovascular knowledge and contribution of Avicenna, current review compiled all his evidence-based concepts of cardiovascular findings from current medical literatures as well as those mentioned in his important medical encyclopedia, the Canon of Medicine. In this review, Avicenna's findings on cardiovascular anatomy such as his description of Willis circle, capillary circulation and arterial and ventricular contractions in the cardiovascular system have been mentioned. Also, his books and manuscripts on cardiology as well as findings and theories on cardiovascular and allied diseases were discussed. These findings are included in his descriptions on cardiac tamponade, stroke, palpitation, atherosclerosis, hypertension, association of the cardiovascular complications with erection and ejaculation, interaction between the heart and emotions as well as some of his mentioned drugs for cardiological disorders and the early concepts of drug targeting. These results can show Avicenna's great contribution to improve the sciences of cardiology in early medieval era. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

  12. Nuclear cardiology for developing countries

    1986-01-01

    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)

    The contribution of interventional cardiology procedures to the population dose in Europe is poorly known. The estimation of the population dose from these procedures requires knowledge of both the typical dose received by patients and an estimate of the number of procedures undertaken annually. Data on the number of cardiology procedures in various European countries are available on the internet for a number of countries. However, this data set is incomplete or out of date. This paper describes the statistical analysis undertaken to estimate the number of interventional cardiology procedures in a number of European countries for 2007. Estimates of the number of procedures are given. On average, the number of cardiac catheterizations per million population is 5346, percutaneous transluminal coronary angioplasty is 1599 and 1214 stent procedures. In addition, there are an estimated 973 pacemaker insertions per million population. (authors)

    Citation classics have been published in many fields of medicine; however, none have focused on interventional cardiology. The goal of this study was to identify the top 100 articles in the field of interventional cardiology and highlight their important trends and characteristics. The Scopus database was used by 2 independent reviewers to extract the top 100 articles using a variety of keywords. We found articles published between 1953 and 2012. Majority (n = 78) of the top 100 articles were published between 1996 and 2010, and the United States was affiliated with the highest number of articles in our list (n = 68). Over half (n = 54) the articles were funded. Private funding was correlated with higher citations (p = 0.036). A third (n = 33) of the papers had authors with conflicts of interest; however, conflict of interest had no effect on citations (p = 0.837). Majority (n = 57) of the articles studied coronary angioplasty and stenting; followed by coronary angiography (n = 14). Women were underrepresented, with only 11 female first authors in the top 100 papers, and only 1 female in the list of top authors who had 5 or more publications. In conclusion, the following features define the typical highly cited article in interventional cardiology-a clinical trial conducted in the United States, which studies angioplasty, and has been published relatively recently in a high-impact journal by a male first author.

    Recent publications have expressed the view that there is a shortage of cardiologists and it is growing worse. Both an increasing demand and a diminishing supply of cardiologists have been projected. An increase in the number of international medical graduates (IMGs) who enter cardiology practice has been proposed as a remedy for a projected shortage. The IMGs have to overcome challenges including clinical practice, language proficiency, and cultural differences before they are incorporated into the fabric of U.S. cardiology. With hard work, perseverance, excellence,compassionate care and support and mentoring, many have contributed to scientific and clinical cardiology in the U.S. Whether in the absence of a present crisis the projected shortage of cardiologists necessitates change in U.S. immigration policy is an open question.

    Although Hippocrates (460-c.375 BC) has been traditionally recognized as the Father of Medicine, the fact that he was seminal in the development of cardiology is much less well known. Evidence is presented to support the notion that Hippocrates could also be considered the Father of Cardiology. Hippocrates also had many of the teachings and practices in common with Confucius (c.551-c.479 BC) and the Yellow Emperor of China (2695-2589 BC). Whereas Confucius was not a physician, the Yellow Emperor was an ancient Chinese physician whose Huang Di Neijing, the Yellow Emperor's Canon of Internal Medicine, is the oldest known treatise of medicine in existence.

    Pediatric syncope is common. Cardiac causes are rarely found. We describe and assess a pragmatic approach to these patients first seen by a pediatric cardiologist in the New England region, using Standardized Clinical Assessment and Management Plans (SCAMPs). Ambulatory patients aged 7 to 21 years initially seen for syncope at participating New England Congenital Cardiology Association practices over a 2.5-year period were evaluated using a SCAMP. Findings were iteratively analyzed and the care pathway was revised. The vast majority (85%) of the 1254 patients had typical syncope. A minority had exercise-related or more problematic symptoms. Guideline-defined testing identified one patient with cardiac syncope. Syncope Severity Scores correlated well between physician and patient perceived symptoms. Orthostatic vital signs were of limited use. Largely incidental findings were seen in 10% of ECGs and 11% of echocardiograms. The 10% returning for follow-up, by design, reported more significant symptoms, but did not have newly recognized cardiac disease. Iterative analysis helped refine the approach. SCAMP methodology confirmed that the vast majority of children referred to the outpatient pediatric cardiology setting had typical low-severity neurally mediated syncope that could be effectively evaluated in a single visit using minimal resources. A simple scoring system can help triage patients into treatment categories. Prespecified criteria permitted the effective diagnosis of the single patient with a clear cardiac etiology. Patients with higher syncope scores still have a very low risk of cardiac disease, but may warrant attention. © 2016 The Authors.

    Specialized cardiology services have contributed to reduced mortality in acute coronary syndromes (ACS).  We sought to evaluate the outcomes of ACS patients admitted to non-cardiology services in Southern Alberta. Retrospective chart review performed on all troponin-positive patients in the Calgary Health Region identified those diagnosed with ACS by their attending team. Patients admitted to non-cardiology and cardiology services were compared, using linked data from the Alberta Provincial Project for Outcomes Assessment in Coronary Heart Disease (APPROACH) registry and the Strategic Clinical Network for Cardiovascular Health and Stroke. From January 1, 2007 to December 31, 2008, 2105 ACS patients were identified, with 1636 (77.7%) admitted to cardiology and 469 (22.3%) to non-cardiology services. Patients admitted to non-cardiology services were older, had more comorbidities, and rarely received cardiology consultation (5.1%). Cardiac catheterization was underutilized (5.1% vs 86.4% in cardiology patients (p cardiology vs. cardiology services (49.1% vs. 11.0% respectively at 4-years, p cardiology services. These patients had worse outcomes, despite adjustment for baseline risk factor differences. Although many patients were appropriately admitted to non-cardiology services, the low use of investigations and secondary prevention medications may contribute to poorer patient outcome. Further research is required to identify process of care strategies to improve outcomes and lessen the burden of illness for patients and the health care system.

    Interventional radiology and cardiology belongs to the imaging modalities connected with significantly higher radiation exposure of patients and medical staff, compared to the exposure during other diagnostic procedures. The objective of this presentation is to promote typical technical parameters and parameters related to the radiation policy, used during the most frequent endovascular and cardiology procedures, as well as the monitoring of the exposure of patients. The presented study reports the results of collecting the data of monitoring doses received by 318 patients undergoing interventional examinations in 3 various departments of the Slovak National Institute of Cardiology and Vascular Diseases. There were 9 different endovascular and cardiology procedures reviewed. The reported patient's radiation exposures were established by using the KAP values, directly shown on the display of the X-ray equipment. From the measured KAP values the entrance surface doses were calculated. Equivalent doses have been measured on hands, legs and other parts of medical staff body, by using electronic dosimeters or thermoluminescent dosimeters. The presented results have covered a wide range of the measured fluoroscopy time values, different number of acquisitions used in various interventional procedures, various cumulated KAP values and also a wide range of the cumulated entrance surface doses. The occupational doses of the operators, followed during dose measurements on their left hands, covered the range from 0.1 μSv to 1513 μSv for one examination performed. The important contribution of the presented results to the radiation protection policy in the Slovak Republic is the mapping of the current situation of the radiation exposure of patients undergoing the chosen interventional examinations and the professional radiation exposure level of interventional operators, providing the most significant interventional procedures in the Slovak interventional hospitals.

    Aim: few nuclear cardiology surveys, were published in the literature, mostly from developed countries. the aim of this study is to perform a nuclear cardiology survey in iran. This may lead to better decision making and programming. Methods and materials: a questionnaire was sent by mail or e- mail to all nuclear medicine centers in iran asking for details of nuclear cardiology practice in year 2002. Also ownership of the center were studied using telephone interviews. Results: 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. Among them, 27 centers were private clinics. There was 69 gamma cameras in these centers, 62.3 % with SPECT capabilities. it is estimated that we may have 100 gamma cameras in Iran. About 85.5 % of centers perform cardiac studies routinely. Tc-99m-MIBI is used in more than 85.7% of the studies and some centers do not use Tl-201. Pharmacological stress with infusion of Dipyridamole is used in 56.7% of the studies and treadmill is the main type of physical exercise (40.2%). SPECT technique was used in 93% of studies including 2.5% of gated SPECT. About 64.3% of centers used two day protocol for imaging.Our study showed that about 65594 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(about 65 millions) nuclear cardiology activity will be about 1.01 study/1000/year. For viability assessment, Tl-201 with rest redistribution technique is used in 10.7 % of cases while re-injection is used in 29.8% of cases and TNG augmented Tc-99m-MIBI injection at rest in 59.5%. Discussion: Activity of nuclear cardiology is about 15 studies/1000 population/year is USA and 2.2 studies/1000/year in Europe. Although it is not uniformly practiced in different countries of Europe, however the numbers indicate that nuclear cardiology is under utilized in Iran ( less

We conducted an online national survey of cardiology fellows during the 2015 to 2016 academic year. Survey questions aimed to assess perceived importance of palliative care education, level of palliative care education during fellowship, and the structure of palliative care support at respondent institutions. Responses were collected anonymously. A total of 519 programs, including subspecialty programs, were contacted. We received 365 responses, a number that represents roughly 14% of all cardiology fellows nationwide during the 2015 to 2016 academic year. Fellows reported discordance in the quality of education between general cardiology and palliative care principles as it relates to care of the patient approaching the end of life. Fellows infrequently received explicit training nor were observed or mentored in delivering end-of-life discussions. Respondents reported an underutilization of palliative care and hospice resources during fellowship training and also a perception that attending faculty were not routinely addressing goals of care. Our survey results highlight a need for enhanced palliative care and end-of-life training experiences for cardiology fellows and also suggest underutilization of hospice and palliative care resources for patients with advanced cardiac diseases. These findings create a platform for future work that might: (1) confirm this training deficit, (2) lead to exploration of educational models that could reconcile this deficit, and (3) potentially help improve palliative care support for patients and families facing advanced heart disease.

  9. Radiation dose to the heart in paediatric interventional cardiology

    2015-01-01

    Recent ICRP publications have reviewed evidence for induction of heart disease. Studies suggest the threshold dose to the heart may be as low as 500 mGy. Doses to the heart from paediatric interventional procedures performed in Glasgow between April 2012 and July 2013 to correct congenital heart defects were investigated to assess the level of potential risk of cardiovascular disease. For common procedures, doses were found to be typically less than 50 mGy, with the highest dose in the period for which data are available estimated to be 330 mGy. These results suggest that any increased risk due to paediatric interventional cardiology is likely to be small, but cumulative doses over a number of years could reach the threshold for effects.

    Social perception skills, such as understanding the mind and emotions of others, affect children's communication abilities in real-life situations. In addition to autism spectrum disorder (ASD), there is increasing knowledge that children with specific language impairment (SLI) also demonstrate difficulties in their social perception abilities. To compare the performance of children with SLI, ASD and typical development (TD) in social perception tasks measuring Theory of Mind (ToM) and emotion recognition. In addition, to evaluate the association between social perception tasks and language tests measuring word-finding abilities, knowledge of grammatical morphology and verbal working memory. Children with SLI (n = 18), ASD (n = 14) and TD (n = 25) completed two NEPSY-II subtests measuring social perception abilities: (1) Affect Recognition and (2) ToM (includes Verbal and non-verbal Contextual tasks). In addition, children's word-finding abilities were measured with the TWF-2, grammatical morphology by using the Grammatical Closure subtest of ITPA, and verbal working memory by using subtests of Sentence Repetition or Word List Interference (chosen according the child's age) of the NEPSY-II. Children with ASD scored significantly lower than children with SLI or TD on the NEPSY-II Affect Recognition subtest. Both SLI and ASD groups scored significantly lower than TD children on Verbal tasks of the ToM subtest of NEPSY-II. However, there were no significant group differences on non-verbal Contextual tasks of the ToM subtest of the NEPSY-II. Verbal tasks of the ToM subtest were correlated with the Grammatical Closure subtest and TWF-2 in children with SLI. In children with ASD correlation between TWF-2 and ToM: Verbal tasks was moderate, almost achieving statistical significance, but no other correlations were found. Both SLI and ASD groups showed difficulties in tasks measuring verbal ToM but differences were not found in tasks measuring non-verbal Contextual ToM. The

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

  12. Radiation monitoring in interventional cardiology: a requirement

    Rivera, T.; Uruchurtu, E. S.

    2017-01-01

    The increasing of procedures using fluoroscopy in interventional cardiology procedures may increase medical and patients to levels of radiation that manifest in unintended outcomes. Such outcomes may include skin injury and cancer. The cardiologists and other staff members in interventional cardiology are usually working close to the area under examination and they receive the dose primarily from scattered radiation from the patient. Mexico does not have a formal policy for monitoring and recording the radiation dose delivered in hemodynamic establishments. Deterministic risk management can be improved by monitoring the radiation delivered from X-ray devices. The objective of this paper is to provide cardiologist, techniques, nurses, and all medical staff an information on DR levels, about X-ray risks and a simple a reliable method to control cumulative dose.

    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. Copyright © 2016 Elsevier Inc. All rights reserved.

  14. Evaluating the benefits of nuclear cardiology

    1996-01-01

    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

  15. A history of cardiology in Jamaica.

    Denbow, C E

    2004-06-01

    The history of cardiology in Jamaica is conveniently considered in decades beginning in the 1950s. The decade of the 1950s was characterized by early descriptions of the pattern of cardiac disease in adults and children in Jamaica, the establishment of a cardiac clinic at the University Hospital of the West Indies and early cardiac surgical landmarks. Extensive preparatory experimental work in the canine laboratory with respect to cardiopulmonary bypass in the early to mid-1960s culminated in the successful completion of the first open heart surgical procedure in April, 1968. Cardiac catheterization was also increasingly developed in the decade of the 1960s. A highlight of the decade of the 1970s was the establishment of the Heart Foundation of Jamaica which began contributing greatly to preventive cardiology in Jamaica by providing a variety of programmes of prevention. In the decade of the 1980s, non-invasive cardiac diagnostic facilities in Jamaica were considerably enhanced by the introduction and development of echocardiography, treadmill exercise testing and ambulatory electrocardiography. In addition, the very important National Rheumatic Fever prevention programme was established. The cardiac catheterization laboratory was re-opened in the 1990s, thus allowing the performance of coronary arteriography in Jamaica for the first time, and interventional cardiology procedures soon followed. The Jamaica Foundation for Cardiac disease was also established in this decade. The vision for the new millennium of "A heart healthy Jamaica in the 21st century" is achievable, but will require appropriate emphasis on expanded preventive and curative cardiology programmes.

  16. Testing typicality in multiverse cosmology

    Science.gov (United States)

    Azhar, Feraz

    2015-05-01

    In extracting predictions from theories that describe a multiverse, we face the difficulty that we must assess probability distributions over possible observations prescribed not just by an underlying theory, but by a theory together with a conditionalization scheme that allows for (anthropic) selection effects. This means we usually need to compare distributions that are consistent with a broad range of possible observations with actual experimental data. One controversial means of making this comparison is by invoking the "principle of mediocrity": that is, the principle that we are typical of the reference class implicit in the conjunction of the theory and the conditionalization scheme. In this paper, we quantitatively assess the principle of mediocrity in a range of cosmological settings, employing "xerographic distributions" to impose a variety of assumptions regarding typicality. We find that for a fixed theory, the assumption that we are typical gives rise to higher likelihoods for our observations. If, however, one allows both the underlying theory and the assumption of typicality to vary, then the assumption of typicality does not always provide the highest likelihoods. Interpreted from a Bayesian perspective, these results support the claim that when one has the freedom to consider different combinations of theories and xerographic distributions (or different "frameworks"), one should favor the framework that has the highest posterior probability; and then from this framework one can infer, in particular, how typical we are. In this way, the invocation of the principle of mediocrity is more questionable than has been recently claimed.

    In the present article, we review publications from the previous year in the following 3 areas: clinical cardiology, geriatric cardiology, and heart failure and transplantation. Among the new developments in clinical cardiology are several contributions from Spanish groups on tricuspid and aortic regurgitation, developments in atrial fibrillation, syncope, and the clinical characteristics of heart disease, as well as various studies on familial heart disease and chronic ischemic heart disease. In geriatric cardiology, the most relevant studies published in 2014 involve heart failure, degenerative aortic stenosis, and data on atrial fibrillation in the geriatric population. In heart failure and transplantation, the most noteworthy developments concern the importance of multidisciplinary units and patients with preserved systolic function. Other notable publications were those related to iron deficiency, new drugs, and new devices and biomarkers. Finally, we review studies on acute heart failure and transplantation, such as inotropic drugs and ventricular assist devices. Copyright © 2014 Sociedad Española de Cardiología.

    Exploring the discrepancy in sex-ratio among interventional cardiologists by analysing the population of the female interventionalist. Despite an increase number of women who graduate from medical school in France during the last generation today, women represent only 24% of all cardiologists and 3% are interventional cardiologists. To face this international gender-based issue of interventional cardiology, committees were established in US (WIN) and recently within the EAPCI: the Women EAPCI chaired by Drs Mehilli and Mauri. In France, the Intervention'Elles committee emerged in order to participate in this concern. As a first initiative, the Intervention'Elles group launched an e-survey to obtain information on the population of French female interventional cardiologists, focused on demography, work patterns, maternity and radiation exposure. Mean age is 40 years old (±7,4), 68% are working in large volume center, 28% have also structural interventional activity. Only 40% have left arm coverage. Despite 80% of French female interventional cardiologists wear personal dosimeters only 45% of them have a dosimetry feedback. Interestingly, even if 54% of women have children (mean: 1.9±1) 28% of them report that childbearing had interfered with their career plan. This questionnaire identifies for the first time the women population in interventional cardiology in France and highlights some of the issues encountered in more detail. This first descriptive step would help to develop strategies for attaining gender equality in interventional cardiology. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

  19. Behavioral cardiology: current advances and future directions.

    Science.gov (United States)

    Rozanski, Alan

    2014-07-08

    Growing epidemiological evidence identifies key domains relevant to behavioral cardiology, including health behaviors, emotions, mental mindsets, stress management, social connectedness, and a sense of purpose. Each of these domains exists along a continuum, ranging from positive factors that promote health, to negative factors, which are pathophysiological. To date, there has been relatively little translation of this growing knowledge base into cardiology practice. Four initiatives are proposed to meet this challenge: 1) promulgating greater awareness of the potency of psychosocial risks factors; 2) overcoming a current "artificial divide" between conventional and psychosocial risk factors; 3) developing novel cost-effective interventions using Internet and mobile health applications, group-based counseling, and development of tiered-care behavioral management; and 4) in recognition that "one size does not fit all" with respect to behavioral interventions, developing specialists who can counsel patients in multidisciplinary fashion and use evidence-based approaches for promoting patient motivation and execution of health goals.

    Sharing deidentified patient-level research data presents immense opportunities to all stakeholders involved in cardiology research and practice. Sharing data encourages the use of existing data for knowledge generation to improve practice, while also allowing for validation of disseminated research. In this review, we discuss key initiatives and platforms that have helped to accelerate progress toward greater sharing of data. These efforts are being prompted by government, universities, philanthropic sponsors of research, major industry players, and collaborations among some of these entities. As data sharing becomes a more common expectation, policy changes will be required to encourage and assist data generators with the process of sharing the data they create. Patients also will need access to their own data and to be empowered to share those data with researchers. Although medicine still lags behind other fields in achieving data sharing's full potential, cardiology research has the potential to lead the way.

    Women are less present on the labor market and many studies have demonstrated the existence of gender differences regarding participation rate and career advancement of women. The process through which job-, career- and research-related choices are structured within the realm of Italian cardiology, is described in this study emphasizing the effects of productivity, gender and family commitments. In June 1996, a questionnaire was mailed to all members of the Italian societies of cardiology. It included mainly (pre-coded) set-choice questions concerning individual characteristics, career-related data, and information pertaining to teaching, scientific and research activity. Returned questionnaires numbered 1715 (21.4% of the total mailed), 83% were completed by males and 17% by females. For both hospital and academic careers, advancement in rank was influenced by variables denoting productivity, family and individual characteristics. Promotion to the upper ranks of the hierarchy was highly dependent upon time (once the effects of the covariates were eliminated). This is a situation that is typical of the internal labor market, that is, of an institution in which staff members are ranked on a hierarchical scale according to formal criteria that are "rigid" and institutionalized, partially and totally sheltered from competition. Therefore, once a member has gained access to the first level of the hierarchy, his/her professional career is to a certain extent pre-determined and the seniority ends up taking on importance in promotion decisions to an appreciable extent; in this field, the weight of seniority on promotion ranges between 30 and 50%.

  2. Is our Universe typical?

    The problem of typicalness of the Universe - as a dynamical system possessing both regular and chaotic regions of positive measure of phase space, is raised and discussed. Two dynamical systems are considered: 1) The observed Universe as a hierarchy of systems of N graviting bodies; 2) (3+1)-manifold with matter evolving to Wheeler-DeWitt equation in superspace with Hawking boundary condition of compact metrics. It is shown that the observed Universe is typical. There is no unambiguous answer for the second system yet. If it is typical too then the same present state of the Universe could have been originated from an infinite number of different initial conditions the restoration of which is practically impossible at present. 35 refs.; 2 refs

    Interventional cardiology procedures are classified as high-dose procedures, owing to increased risk for radiation skin injuries and stochastic effects, such as cancer. European MED Directive 97/43 requires special consideration and dose evaluation for this kind of procedures . Dose received by a patient, in general, depends on the radiological equipment, examination protocol, the way it is implemented, the patient's body weight and nature of disease. Long-term fluoroscopy of certain parts of the body, a significant body mass, high-value dose intensity, continuous rather than pulsed fluoroscopy, small focus-skin distance and repeated procedure on the same patient, are among the factors that can lead to radiation skin injuries. A particular challenge is the fact that the radiation damage of the skin is difficult to detect and connect to the previously conducted cardiologic procedures. The fact that such injuries do not have immediate manifestation is very often reason that many of them remain undetected. The purpose of this work is to assess the level of radiation dose to patients in percutaneous coronary interventions (PCI) and to investigate possibility for setting of a practical trigger value if dose quantities exceed certain levels in terms of dose descriptors available at display of interventional cardiology unit. Two dedicated interventional cardiology units in a large teaching cardiac centre (Clinical Centre of Serbia, Belgrade, Serbia) were included in the survey. Both rooms (D and F) were equipped with X-ray units of the identical model: Siemens Axiom Artis (Siemens, Erlangen, Germany) with the flat panel detector and integrated ionization chamber to measure air kerma-area product (P K A) and air kerma in international reference point (K I RP). Patient doses were assessed in terms of P K A, K I RP and maximum-skin dose (MSD). P K A and K I RP were assessed using a built-in, in situ calibrated dosimeters, while MSD was estimated using radiochromic films

    Recent studies have reported a significant increase in eye lens opacities among staff in the cardiac catheterization laboratory but indicated further studies are needed to confirm the findings. To evaluate the prevalence of opacities in eyes of cardiologists, radiographers and nurses working in interventional cardiology. The eyes of 52 staff in interventional cardiology facilities and 34 age- and sex-matched unexposed controls were screened in a cardiology conference held in Kuala Lumpur by dilated slit-lamp examination, and posterior lens changes were graded. Individual cumulative lens X-ray exposures were calculated from responses to a questionnaire in terms of workload and working practice. The prevalence of posterior lens opacities among interventional cardiologists was 53%, while in nurses and radiographers it was 45%. Corresponding relative risks were 2.6 (95% CI: 1.2-5.4) and 2.2 (95% CI: 0.98-4.9), for interventional cardiologists and support staff, respectively. This study confirms a statistically significant increase in radiation-associated posterior lens changes in the eyes of interventional cardiology staff. Copyright © 2012 S. Karger AG, Basel.

    The work of Tversky and Kahneman on intuitive probability judgment leads to the following prediction: The judged probability that an instance belongs to a category is an increasing function of the typicality of the instance in the category. To test this prediction, subjects in Experiment 1 read a description of a person (e.g., "Linda is 31, bright, ... outspoken") followed by a category. Some subjects rated how typical the person was of the category, while others rated the probability that the person belonged to that category. For categories like bank teller and feminist bank teller: (1) subjects rated the person as more typical of the conjunctive category (a conjunction effect); (2) subjects rated it more probable that the person belonged to the conjunctive category (a conjunction fallacy); and (3) the magnitudes of the conjunction effect and fallacy were highly correlated. Experiment 2 documents an inclusion fallacy, wherein subjects judge, for example, "All bank tellers are conservative" to be more probable than "All feminist bank tellers are conservative." In Experiment 3, results parallel to those of Experiment 1 were obtained with respect to the inclusion fallacy.

    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.

    Enigmas often lead to hypotheses and speculations. For this reason, especially for the sake of the reader's motivation, we opted for the plain discussion of some cardiology enigmas. The present text was aimed to discuss speculatively some cardiology enigmas. Text was freely designed in the context of coronary artery and heart valve diseases. The results were presented as the combination enigma/hypothesis. 1) The absence of arteriosclerosis in intramyocardial coronary arteries/ endothelium-myocardial interaction (crosstalk); 2) The unique and always confirmed superior evolution of the internal thoracic artery as coronary graft/ higher NO basal release 3) The prophylactic left internal thoracic artery graft in mildlystenosed coronary lesions/need of more accurate functional imaging techniques; 4) The high incidence of perioperative atrial fibrillation in patients with coronary artery disease/atrial ischemia associated to left circumflex coronary lesions; 5) The handling of disease-free saphenous vein grafts at the time of reoperation/biological serendipity with graft vein segments; 6) The possible aortic stenosis protection against coronary artery disease/ endothelium-myocardium interaction (crosstalk) improving NO release. The discussed topics associated with their respective speculative hypothesis remain as enigmas, but would become motivations for investigations.

    During the last 10 years, there have been major technological achievements in pediatric interventional cardiology. In addition, there have been several advances in cardiac imaging, especially in 3-dimensional imaging of echocardiography, computed tomography, magnetic resonance imaging, and cineangiography. Therefore, more types of congenital heart diseases can be treated in the cardiac catheter laboratory today than ever before. Furthermore, lesions previously considered resistant to interventional therapies can now be managed with high success rates. The hybrid approach has enabled the overcoming of limitations inherent to percutaneous access, expanding the application of endovascular therapies as adjunct to surgical interventions to improve patient outcomes and minimize invasiveness. Percutaneous pulmonary valve implantation has become a successful alternative therapy. However, most of the current recommendations about pediatric cardiac interventions (including class I recommendations) refer to off-label use of devices, because it is difficult to study the safety and efficacy of catheterization and transcatheter therapy in pediatric cardiac patients. This difficulty arises from the challenge of identifying a control population and the relatively small number of pediatric patients with congenital heart disease. Nevertheless, the pediatric interventional cardiology community has continued to develop less invasive solutions for congenital heart defects to minimize the need for open heart surgery and optimize overall outcomes. In this review, various interventional procedures in patients with congenital heart disease are explored.

  15. The use of MR in cardiological diagnostics

    2004-01-01

    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

    The aim of this study was to assess cardiological manifestations of carbon monoxide (CO) poisoning. Background/introduction: Carbon monoxide intoxication is one of the most important toxicological causes of morbidity and mortality worldwide. Early clinical manifestation of CO poisoning is cardiotoxicity. We enrolled 75 patients (34 males and 41 females, mean age 37.6 ± 17.7 y/o) hospitalized due to CO poisoning. Laboratory tests including troponin I, blood pressure measurements, HR and electrocardiograms (ECG) were collected. Pach's scale scoring and grading system was used to establish severity of poisoning. Grade of poisoning is positively correlated with troponin I levels and systolic blood pressure. Moreover, troponin levels are significantly correlated with exposition time, lactates and are higher in tachycardiac, hypertensive and positive ECG subpopulations. COHb levels are indicative of exposure but do not correlate with grade of poisoning. The main cause of CO poisoning were bathroom heaters - 83%, only 11% of examined intoxicated population were equipped with CO detectors. Complex cardiological screening covering troponin levels, ECG, blood pressure and heart rate measurements as well as complete blood count with particular attention to platelet parameters should be performed in each case where CO intoxication is suspected. More emphasis on education on CO poisoning is needed.

    Data mining (DM) provides the methodology and technology needed to transform huge amounts of data into useful information for decision making. It is a powerful process employed to extract knowledge and discover new patterns embedded in large data sets. Data mining has been increasingly used in medicine, particularly in cardiology. In fact, DM applications can greatly benefit all those involved in cardiology, such as patients, cardiologists and nurses. The purpose of this paper is to review papers concerning the application of DM techniques in cardiology so as to summarize and analyze evidence regarding: (1) the DM techniques most frequently used in cardiology; (2) the performance of DM models in cardiology; (3) comparisons of the performance of different DM models in cardiology. We performed a systematic literature review of empirical studies on the application of DM techniques in cardiology published in the period between 1 January 2000 and 31 December 2015. A total of 149 articles published between 2000 and 2015 were selected, studied and analyzed according to the following criteria: DM techniques and performance of the approaches developed. The results obtained showed that a significant number of the studies selected used classification and prediction techniques when developing DM models. Neural networks, decision trees and support vector machines were identified as being the techniques most frequently employed when developing DM models in cardiology. Moreover, neural networks and support vector machines achieved the highest accuracy rates and were proved to be more efficient than other techniques. Copyright © 2016 Elsevier Ireland Ltd.

    Widimský, J

    2013-06-01

    The paper presents the origins of the Czech Society of Cardiology on the one hand, and the origins of Czech cardiology on the other. The Czech Society of Cardiology is the third oldest in the world (after the American and German Societies). It was founded in 1929 by Prof. Libenský. As early as in 1933, the Society organised the first international congress of cardiologists in Prague, which was attended by 200 doctors, out of which 50 were from abroad. The most participants came from France and Poland. Other participants came from England, Argentina, Belgium, the Netherlands, Italy, Romania, Spain and Switzerland. The worldwide importance of this congress is apparent from the fact that both the World Society of Cardiology and the European Society of Cardiology (EKS) were founded after World War II in the years 1950 and 1952, i.e. almost 20 years after the first international congress of cardiology in Prague. In 1964, the Fourth Congress of European Society of Cardiology was held in Prague with the participation of 1,500 specialists from 31 countries and chaired by Prof. Pavel Lukl, the later president of EKS (1964- 1968). The paper also presents the work of our specialists in WHO and the history of the international journal Cor et Vasa issued by the Avicenum publishing house in Prague in English and Russian in the years 1958- 1992. An important role in the development of our cardiology was played by certain departments and clinics. In 1951, the Institute for Cardiovascular Research (ÚCHOK) was founded in PrahaKrč, thanks to the initiative of MU Dr. František Kriegl, the Deputy Minister of Health. Its first director was Klement Weber, who published, as early as in 1929, a monograph on arrhythmias -  50 years earlier than arrhythmias started to be at the centre of attention of cardiologists. Klement Weber was one of the doctors of President T. G. Masaryk during his serious disease towards the end of his life. Jan Brod was the deputy of Klement Weber in the

    The American College of Cardiology Adult Congenital and Pediatric Cardiology (ACPC) Section had attempted to create quality metrics (QM) for ambulatory pediatric practice, but limited evidence made the process difficult. The ACPC sought to develop QMs for ambulatory pediatric cardiology practice. Five areas of interest were identified, and QMs were developed in a 2-step review process. In the first step, an expert panel, using the modified RAND-UCLA methodology, rated each QM for feasibility and validity. The second step sought input from ACPC Section members; final approval was by a vote of the ACPC Council. Work groups proposed a total of 44 QMs. Thirty-one metrics passed the RAND process and, after the open comment period, the ACPC council approved 18 metrics. The project resulted in successful development of QMs in ambulatory pediatric cardiology for a range of ambulatory domains. Copyright © 2017 American College of Cardiology Foundation.

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

    International Nuclear Information System (INIS)

    2014-02-01

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

  2. Application of Contrast Echocardiography in Invasive Cardiology

    Directory of Open Access Journals (Sweden)

    2010-12-01

    Full Text Available Contrast echocardiography by rendering better imaging of the borders of cardiac chambers is a useful tool for evaluating cardiac function, mass, myocardial vascularization, microvascular structure (small vessel vasculature and viability. Contrast was first started to be used for patients with suboptimal image quality. It can be used in detecting defects in myocardial blood supply in patients with chest pain and determining the success of interventionalprocedures. It can also be of help in demonstrating myocardial viability after reperfusion treatment in patients who had myocardial infarction. It is expected to be used more widely in invasive cardiology for decision making, guiding and determining the success of the procedures. Advances in imaging techniques , development of contrast materials for evaluation of left system, contrast echocardiography may become a routine clinical practice.

    In recent years Cardiologists have shown an increasing interest on the use of Magnetic Resonance Imaging (MRI) for assessing cardiovascular diseases. The first generation of MRI equipment dedicated to cardiology is now available. The MRI Laboratory of Clinical Physiology Institute in Pisa has joined a multi-centric international project for the development of prototype of this dedicated machine and is currently involved in several subprojects such as the study of myocardial perfusion and the assessment of congenital heart diseases. An interdisciplinary group (cardiologists, software and hardware engineers, biologists, etc.) is full time involved in the development of new analysis algorithms, etc. The new concept of installing a MRI machine within clinical cardiovascular department has started to induce fruitful cooperations either in the research field or in the clinical setting [it

  4. A Typical Synergy

    Science.gov (United States)

    van Noort, Thomas; Achten, Peter; Plasmeijer, Rinus

    We present a typical synergy between dynamic types (dynamics) and generalised algebraic datatypes (GADTs). The former provides a clean approach to integrating dynamic typing in a statically typed language. It allows values to be wrapped together with their type in a uniform package, deferring type unification until run time using a pattern match annotated with the desired type. The latter allows for the explicit specification of constructor types, as to enforce their structural validity. In contrast to ADTs, GADTs are heterogeneous structures since each constructor type is implicitly universally quantified. Unfortunately, pattern matching only enforces structural validity and does not provide instantiation information on polymorphic types. Consequently, functions that manipulate such values, such as a type-safe update function, are cumbersome due to boilerplate type representation administration. In this paper we focus on improving such functions by providing a new GADT annotation via a natural synergy with dynamics. We formally define the semantics of the annotation and touch on novel other applications of this technique such as type dispatching and enforcing type equality invariants on GADT values.

    2004-01-01

    Objective: To evaluate the criteria for cardiology referrals and to assess the perioperative relevance of the cardiology advice given in patients evaluated for non-cardiac surgery. Materials and Methods: A review of case files of 70 patients, scheduled for non-cardiac surgery, who were referred for cardiology consultations from the Anaesthesia Clinic at AKUH during the study period. The clinical criteria for seeking cardiology advice, the cardiology advice given, its influence on patient management, as well as number of adverse cardiac events in the perioperative period were documented. Results: A history of hypertension, ischemic heart disease, and ECG abnormalities were the major criteria for seeking opinion on cardiac status. Cardiology advice frequently resulted in the ordering of extensive cardiac investigations. Among the patients identified for further tests by the cardiologists, 75% had no evidence of ischemic heart disease or myocardial dysfunction; none of them were monitored invasively intraoperatively or had adverse cardiac events in the perioperative period requiring intensive care or prolonged hospital stay. Conclusion: No definite criteria or pattern for referrals was identified. Most of the referrals did not fall within the AHA guidelines. Cardiology advice given had very little influence on the perioperative management. (author)

  7. Career choices for cardiology: cohort studies of UK medical graduates

    Science.gov (United States)

    2013-01-01

    Background Cardiology is one of the most popular of the hospital medical specialties in the UK. It is also a highly competitive specialty in respect of the availability of higher specialty training posts. Our aims are to describe doctors’ early intentions about seeking careers in cardiology, to report on when decisions about seeking a career in cardiology are made, to compare differences between men and women doctors in the choice of cardiology, and to compare early career choices with later specialty destinations. Methods Questionnaire surveys were sent to all UK medical graduates in selected qualification years from 1974–2009, at 1, 3, 5, 7 and 10 years after graduation. Results One year after graduation, the percentage of doctors specifying cardiology as their first choice of long-term career rose from the mid-1990s from 2.4% (1993 cohort) to 4.2% (2005 cohort) but then fell back to 2.7% (2009 cohort). Men were more likely to give cardiology as their first choice than women (eg 4.1% of men and 1.9% of women in the 2009 cohort). The percentage of doctors who gave cardiology as their first choice of career declined between years one and five after qualification: the fall was more marked for women. 34% of respondents who specified cardiology as their sole first choice of career one year post-graduation were later working in cardiology. 24% of doctors practising as cardiologists several years after qualification had given cardiology as their sole first choice in year one. The doctors’ ‘domestic circumstances’ were a relatively unimportant influence on specialty choice for aspiring cardiologists, while ‘enthusiasm/commitment’, ‘financial prospects’, ‘experiences of the job so far’ and ‘a particular teacher/department’ were important. Conclusions Cardiology grew as a first preference one year after graduation to 2005 but is now falling. It consistently attracts a higher percentage of men than women doctors.

    Nuclear cardiology is no longer a medical discipline residing solely in nuclear medicine. This is the first book to recognize this fact by integrating in-depth information from both the clinical cardiology and nuclear cardiology literature, and acknowledging cardiovascular medicine as the fundamental knowledge base needed for the practice of nuclear cardiology. The book is designed to increase the practitioner's knowledge of cardiovascular medicine, thereby enhancing the quality of interpretations through improved accuracy and clinical relevance.The text is divided into four sections covering all major topics in cardiology and nuclear cardiology: -Basic Sciences and Cardiovascular Diseases; -Conventional Diagnostic Modalities; -Nuclear Cardiology; -Management of Cardiovascular Diseases.

    Transthoracic echocardiography (TTE) is a non-invasive diagnostic modality for children with suspected heart disease. The American College of Cardiology published Appropriate Use Criteria (AUC) for an initial outpatient pediatric TTE in 2014 to promote effective care and improve resource utilization. The objective was to determine the appropriateness of TTE per the published AUC in a single academic pediatric cardiology clinic as a baseline performance quality measure. The echocardiography database was used to identify initial outpatient TTE in children during January-March 2014. TTE indications (appropriate [A], may be appropriate [M], or rarely appropriate [R]) and findings (normal, incidental, or abnormal) were recorded. The effect of AUC and age groups on yield of abnormal TTE findings was analyzed. Of the 2166 screened studies, our study cohort consisted of 247 TTEs. Indications rated A, M, and R were found in 129, 27, and 90, respectively, and 1 was unclassifiable. Majority of TTE (n = 183) were normal, although incidental findings were noted in 32 and abnormal findings in 32 cases. Abnormal findings were noted in 26/129 of A, 2/27 of M, and 4/90 of R. Indications rated A were significantly associated with yield of abnormal TTE findings, adjusted by age group. Infants and adolescents were more likely to have abnormal TTE findings compared to young children. Recently published AUC were validated for initial TTE in the outpatient pediatric cardiology clinic. Appropriateness rated by AUC was highly associated with yield of abnormal TTE findings and worked best in infants and adolescent.

    The future is always hard to forecast but the prospect of nuclear cardiology has never been more unobtainable than these days. Myocardial perfusion single-photon emission computed tomography (MPS) has been one of the major nuclear medicine studies for decades, but the annual number of MPS is stagnant or steadily decreasing in Korea and other countries. The challenge from coronary computed tomography (CCT) and the concern of radiation exposure of MPS were the main reasons for the stalemate of nuclear cardiology. Compared to the rapid technological progress of CCT, enabling greater image resolution in conjunction with lower radiation exposure to the patients, development of new radiopharmaceuticals or scintillation imaging techniques has been at a relatively slow pace. Therefore, the future of nuclear cardiology is really dependent on the application of the genuine nuclear medicine principle to patient's management. The review for current update of nuclear cardiology will ensue in the next issue of Nuclear Medicine and Molecular Imaging.

    The vast variability of the overall rare congenital anomalies of the inferior vena cava (IVC) are mostly detected by accident through different imaging modalities. These cannot be classed as pathological findings, and should not be confused with lymphomas and has to differ from secondary collateral venous pathways. Based on 656 CT examinations 10.5% known forms of IVC anomalies were found. According to the embryological development three main groups of IVC variants could be nosologically classified: agenesis of the suprarenal IVC, anomalies of the pars renalis and anomalies of the infrarenal IVC. Additionally three unusual anomaly complexes were found. For the understanding details of the embryology based on a simplified depiction are presented. (orig.)

    Coronary artery disease is on the rise over the world. Myocardial perfusion SPECT is a well established technique to detect coronary artery disease and to assess left ventricular function. In addition, it has the unique ability to predict the prognosis of the patients. Moreover, the application of ECG-gated images provided the quantitative data and improved the accuracy. This approach has been proved to be cost-effective and suitable for the emerging economies as well as developed countries. However, the utilization of nuclear cardiology procedures vary widely considering the different countries and region of the world. Korea exits 2-3 times less utilization than Japan, and 20 times than the United States. Recently, with the emerging of new technology, namely cardiac CT, cardiac MR and stress echocardiography, the clinical usefulness of nuclear cardiology has been called in question and its role has been redefined. For the proper promotion of nuclear cardiology, special educations should be conducted since the nuclear cardiology has the contact points between nuclear medicine and cardiology. Several innovations are in horizon which will impact the diagnostic accuracy as well as imaging time and cost savings. Development of new tracers, gamma camera technology and hybrid systems will open the new avenue in cardiac imaging. The future of nuclear cardiology based on molecular imaging is very exciting. The newly defined biologic targets involving atherosclerosis and vascular vulnerability will allow the answers for the key clinical questions. Hybrid techniques including SPECT/CT indicate the direction in which clinical nuclear cardiology may be headed in the immediate future. To what extent nuclear cardiology will be passively absorbed by other modalities, or will actively incorporate other modalities, is up to the present and next generation of nuclear cardiologists

    Achieving competency at electrocardiogram (ECG) interpretation among cardiology subspecialty residents has traditionally focused on interpreting a target number of ECGs during training. However, there is little evidence to support this approach. Further, there are no data documenting the competency of ECG interpretation skills among cardiology residents, who become de facto the gold standard in their practice communities. We tested 29 Cardiology residents from all 3 years in a large training program using a set of 20 ECGs collected from a community cardiology practice over a 1-month period. Residents interpreted half of the ECGs using a standard analytic framework, and half using their own approach. Residents were scored on the number of correct and incorrect diagnoses listed. Overall diagnostic accuracy was 58%. Of 6 potentially life-threatening diagnoses, residents missed 36% (123 of 348) including hyperkalemia (81%), long QT (52%), complete heart block (35%), and ventricular tachycardia (19%). Residents provided additional inappropriate diagnoses on 238 ECGs (41%). Diagnostic accuracy was similar between ECGs interpreted using an analytic framework vs ECGs interpreted without an analytic framework (59% vs 58%; F(1,1333) = 0.26; P = 0.61). Cardiology resident proficiency at ECG interpretation is suboptimal. Despite the use of an analytic framework, there remain significant deficiencies in ECG interpretation among Cardiology residents. A more systematic method of addressing these important learning gaps is urgently needed. Copyright © 2014 Canadian Cardiovascular Society. Published by Elsevier Inc. All rights reserved.

  18. Interventional Cardiology for Congenital Heart Disease.

    Science.gov (United States)

    Kenny, Damien

    2018-05-01

    Congenital heart interventions are now replacing surgical palliation and correction in an evolving number of congenital heart defects. Right ventricular outflow tract and ductus arteriosus stenting have demonstrated favorable outcomes compared to surgical systemic to pulmonary artery shunting, and it is likely surgical pulmonary valve replacement will become an uncommon procedure within the next decade, mirroring current practices in the treatment of atrial septal defects. Challenges remain, including the lack of device design focused on smaller infants and the inevitable consequences of somatic growth. Increasing parental and physician expectancy has inevitably lead to higher risk interventions on smaller infants and appreciation of the consequences of these interventions on departmental outcome data needs to be considered. Registry data evaluating congenital heart interventions remain less robust than surgical registries, leading to a lack of insight into the longer-term consequences of our interventions. Increasing collaboration with surgical colleagues has not been met with necessary development of dedicated equipment for hybrid interventions aimed at minimizing the longer-term consequences of scar to the heart. Therefore, great challenges remain to ensure children and adults with congenital heart disease continue to benefit from an exponential growth in minimally invasive interventions and technology. This can only be achieved through a concerted collaborative approach from physicians, industry, academia and regulatory bodies supporting great innovators to continue the philosophy of thinking beyond the limits that has been the foundation of our specialty for the past 50 years.

    There have been substantial improvements made in the tools and techniques used since the advent of percutaneous coronary intervention. What was primarily developed as a treatment of coronary artery disease is now used to address a variety of structural heart disease problems. The outcomes have been remarkably successful with relatively low complication rates that rival the results of open-heart surgery. This article will review some of the new devices available for management of structural cardiac conditions including congenital defects and acquired valvular abnormalities. Transcatheter treatment offers advantages over surgical intervention in recovery time, improved patient satisfaction, lower procedural risk, and avoidance of cardio-pulmonary bypass especially in high-risk patients. We will discuss different medical conditions and introduce the devices used to treat these conditions. Each device or technique has benefits and risks, and familiarity with the devices along with patient selection will best optimize the outcome. Copyright © 2014 Japanese College of Cardiology.

    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.

  1. Filter's importance in nuclear cardiology imaging

    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.

    This review discusses the basics of cardiovascular gene therapy, the results of recent human clinical trials, and the rapid progress in imaging techniques in cardiology. Improved understanding of the molecular and genetic basis of coronary heart disease has made gene therapy a potential new alternative for the treatment of cardiovascular diseases. Experimental studies have established the proof-of-principle that gene transfer to the cardiovascular system can achieve therapeutic effects. First human clinical trials provided initial evidence of feasibility and safety of cardiovascular gene therapy. However, phase II/III clinical trials have so far been rather disappointing and one of the major problems in cardiovascular gene therapy has been the inability to verify gene expression in the target tissue. New imaging techniques could significantly contribute to the development of better gene therapeutic approaches. Although the exact choice of imaging modality will depend on the biological question asked, further improvement in image resolution and detection sensitivity will be needed for all modalities as we move from imaging of organs and tissues to imaging of cells and genes.

    As in other fields, understanding of vascular risk and rehabilitation is constantly improving. The present review of recent epidemiological update shows how far we are from achieving good risk factor control: in diet and nutrition, where unhealthy and excessive societal consumption is clearly increasing the prevalence of obesity; in exercise, where it is difficult to find a balance between benefit and risk, despite systemization efforts; in smoking, where developments center on programs and policies, with the electronic cigarette seeming more like a problem than a solution; in lipids, where the transatlantic debate between guidelines is becoming a paradigm of the divergence of views in this extensively studied area; in hypertension, where a nonpharmacological alternative (renal denervation) has been undermined by the SYMPLICITY HTN-3 setback, forcing a deep reassessment; in diabetes mellitus, where the new dipeptidyl peptidase-4 and sodium-glucose cotransporter type 2 inhibitors and glucagon like peptide 1 analogues have contributed much new information and a glimpse of the future of diabetes treatment, and in cardiac rehabilitation, which continues to benefit from new information and communication technologies and where clinical benefit is not hindered by advanced diseases, such as heart failure. Our summary concludes with the update in elderly patients, whose treatment criteria are extrapolated from those of younger patients, with the present review clearly indicating that should not be the case.

    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.

    Introduction New paediatric cardiology trainees are required to rapidly assimilate knowledge and gain clinical skills to which they have limited or no exposure during residency. The Pediatric Cardiology Fellowship Boot Camp (PCBC) at Boston Children's Hospital was designed to provide incoming fellows with an intensive exposure to congenital cardiac pathology and a broad overview of major areas of paediatric cardiology practice. The PCBC curriculum was designed by core faculty in cardiac pathology, echocardiography, electrophysiology, interventional cardiology, exercise physiology, and cardiac intensive care. Individual faculty contributed learning objectives, which were refined by fellowship directors and used to build a programme of didactics, hands-on/simulation-based activities, and self-guided learning opportunities. A total of 16 incoming fellows participated in the 4-week boot camp, with no concurrent clinical responsibilities, over 2 years. On the basis of pre- and post-PCBC surveys, 80% of trainees strongly agreed that they felt more prepared for clinical responsibilities, and a similar percentage felt that PCBC should be offered to future incoming fellows. Fellows showed significant increase in their confidence in all specific knowledge and skills related to the learning objectives. Fellows rated hands-on learning experiences and simulation-based exercises most highly. We describe a novel 4-week-long boot camp designed to expose incoming paediatric cardiology fellows to the broad spectrum of knowledge and skills required for the practice of paediatric cardiology. The experience increased trainee confidence and sense of preparedness to begin fellowship-related responsibilities. Given that highly interactive activities were rated most highly, boot camps in paediatric cardiology should strongly emphasise these elements.

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

    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)

    A 28-year-old female patient developed neurological symptoms after a classical episode of dengue. The physical examination reveled no fever, no neurological focalization, and an altered mental status (Glasgow 12/15). Magnetic resonance imaging confirmed the diagnosis of acute disseminated encephalomyelitis. The patient showed clinical improvement following treatment with steroids. Acute disseminated encephalomyelitis (ADEM) is classically described as a uniphasic syndrome occurring in association with systemic viral infection (parainfectious encephalomyelitis) or immunization or vaccination (post vaccination encephalomyelitis). Pathologically, there is perivascular inflammation, edema, and demyelination within the CNS. Clinically, patients present with rapidly progressing focal or multifocal neurologic dysfunction. The treatment for ADEM is targeted at suppressing inflammation in the brain through the use of anti-inflammatory drugs such as intravenous corticosteroids.

    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.

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

    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

    The population of older adults is expanding rapidly and aging predisposes to cardiovascular disease. The principle of patient-centered care must respond to the preponderance of cardiac disease that now occurs in combination with complexities of old age. Geriatric cardiology melds cardiovascular perspectives with multimorbidity, polypharmacy, frailty, cognitive decline, and other clinical, social, financial, and psychological dimensions of aging. While some assume a cardiologist may instinctively cultivate some of these skills over the course of a career, we assert that the volume and complexity of older cardiovascular patients in contemporary practice warrants a more direct approach to achieve suitable training and a more reliable process of care. We present a rationale and vision for geriatric cardiology as a melding of primary cardiovascular and geriatrics skills, and thereby infusing cardiology practice with expanded proficiencies in diagnosis, risks, care coordination, communications, end-of-life, and other competences required to best manage older cardiovascular patients.

  12. Is patient size important in dose determination and optimization in cardiology?

    2003-01-01

    Patient dose determination and optimization have become more topical in recent years with the implementation of the Medical Exposures Directive into national legislation, the Ionising Radiation (Medical Exposure) Regulations. This legislation incorporates a requirement for new equipment to provide a means of displaying a measure of patient exposure and introduces the concept of diagnostic reference levels. It is normally assumed that patient dose is governed largely by patient size; however, in cardiology, where procedures are often very complex, the significance of patient size is less well understood. This study considers over 9000 cardiology procedures, undertaken throughout the north of England, and investigates the relationship between patient size and dose. It uses simple linear regression to calculate both correlation coefficients and significance levels for data sorted by both room and individual clinician for the four most common examinations, left ventrical and/or coronary angiography, single vessel stent insertion and single vessel angioplasty. This paper concludes that the correlation between patient size and dose is weak for the procedures considered. It also illustrates the use of an existing method for removing the effect of patient size from dose survey data. This allows typical doses and, therefore, reference levels to be defined for the purposes of dose optimization

    Cardiology fellowship programs are at the interface of medical education and the care of patients suffering from the leading cause of mortality in the United States, yet there is an apparent lack of research guiding the effective education of fellows. We sought to quantify the number of publications in cardiology journals that pertained to the education of cardiology trainees and the number of cardiologists participating in education research. For the period between January and December 2012, we cataloged cardiology-specific and general medical/medical education journals and sorted them by impact factor. Tables of content were reviewed for articles with an educational focus, a cardiology focus, or both. We recorded the authors' areas of medical training, and keywords from each cardiology journal's mission statement were reviewed for emphasis on education. Twenty-six cardiology journals, containing 6645 articles, were reviewed. Only 4 articles had education themes. Ten general medical and 15 medical education journals contained 6810 articles. Of these, only 7 focused on medical education in cardiology, and none focused on cardiology fellowship training. Among the 4887 authors of publications in medical education journals, 25 were cardiologists (less than 1%), and among the 1036 total words in the mission statements of all cardiology journals, the term "education" appeared once. Published educational research is lacking in cardiology training, and few cardiologists appear to be active members of the education scholarship community. Cardiology organizations and academic journals should support efforts to identify target areas of study and publish scholarship in educational innovation.

    Full text: Despite of very fast developments in the field of Interventional Cardiology, the level of doses received by medical staff is still substantial and therefore must be routinely controlled. The annual dose limits established by International Commission on Radiological Protection are monitored by the personal dosimeters worn under the lead apron. In this method the information about doses on uncovered body parts can be only approximated. Values obtained by means of ring or wrist dosimetry are also insufficient to provide basis for conclusions on the extremities doses received by medical staff. The main purpose of this study was to investigate radiation doses absorbed for eye-lenses and extremities to personnel participating in cardiac procedures. The doses were measured using highly sensitive thermoluminescent dosimeters (LiF: Mg, Cu, P), calibrated in Secondary Standard Dosimetry Laboratory for X-ray beam typical of cardiac procedures. TLDs were placed in three locations: in a special band on eyebrow ridge, on a left ankle and on a left hand (finger's ring). Considerable amount of detectors used allowed determining the actual distribution of doses. Mean equivalent doses per procedure for Coronary Angiography (CAG) and Coronary Angiography with Percutaneous Transluminal Coronary Angioplasty (CAG+PTCA) were investigated. For CAG these values amounted to: on left eyebrow ridge from 80 μSv to 140 μSv, on right eyebrow ridge from 30 μSv to 75 μSv, on ankle from 80 μSv to 110 μSv and on hand from 190 μSv to 240 μSv, respectively. For CAG+PTCA the observed levels were: on left eyebrow ridge from 170 μSv to 240 μSv, on right eyebrow ridge from 60 μSv to 160 μSv, on ankle from 180 μSv to 270 μSv and on hand from 410 μSv to 590 μSv, respectively. The wild range of doses for both eyebrow ridges was especially visible and depend on operation position with respect to X-ray tube. The eye-lens doses will be measured using a Randoman anthropomorphic phantom

    Ionizing radiation management is among the most important safety issues in interventional cardiology. Multiple radiation protection measures allow the minimization of x-ray exposure during interventional procedures. Our purpose was to assess the utilization and effectiveness of radiation protection and optimization techniques among interventional cardiologists in Lithuania. Interventional cardiologists of five cardiac centres were interviewed by anonymized questionnaire, addressing personal use of protective garments, shielding, table/detector positioning, frame rate (FR), resolution, field of view adjustment and collimation. Effective patient doses were compared between operators who work with and without x-ray optimization. Thirty one (68.9%) out of 45 Lithuanian interventional cardiologists participated in the survey. Protective aprons were universally used, but not the thyroid collars; 35.5% (n  =  11) operators use protective eyewear and 12.9% (n  =  4) wear radio-protective caps; 83.9% (n  =  26) use overhanging shields, 58.1% (n  =  18)-portable barriers; 12.9% (n  =  4)-abdominal patient's shielding; 35.5% (n  =  11) work at a high table position; 87.1% (n  =  27) keep an image intensifier/receiver close to the patient; 58.1% (n  =  18) reduce the fluoroscopy FR; 6.5% (n  =  2) reduce the fluoro image detail resolution; 83.9% (n  =  26) use a 'store fluoro' option; 41.9% (N  =  13) reduce magnification for catheter transit; 51.6% (n  =  16) limit image magnification; and 35.5% (n  =  11) use image collimation. Median effective patient doses were significantly lower with x-ray optimization techniques in both diagnostic and therapeutic interventions. Many of the ionizing radiation exposure reduction tools and techniques are underused by a considerable proportion of interventional cardiology operators. The application of basic radiation protection tools and

    Health services are systems whose mission is to improve the health status of both individuals and society in general. In recent decades, these systems have faced challenges such as their increasing complexity, limited resources, rapid innovation and diffusion of medical technologies, pressures on demand from society and professionals, and the lack of knowledge of the effects of these factors on costs and society's health. In addition, health care expenditures have grown twice as fast as wealth in industrialized countries during the last 25 years. These problems have prompted cost containment as a key issue in health policy and, at the same time, have promoted the development of socioeconomic evaluation as a scientific activity in the frame of health services research. Socioeconomic evaluation tries to determine if the sacrifice made by society, which devotes part of its limited resources to health care, maximizes the outcomes for population. This article describes basic concepts and methods of economic appraisal in health services which are illustrated with examples of clinical practice in cardiology. Common methods of evaluation are described; the relation between the clinical outcome of a procedure and its associated costs is emphasized in explaining the types of efficiency analysis (cost-efficacy, cost-effectiveness, cost-utility, and cost-benefit); and finally a guide for socioeconomic evaluation is provided.

    The role of women and foreign medical graduates (FMGs) in cardiology research published in the United States has received limited study. We examined the characteristics of the first and last authors of all original contributions and review articles published in the Journal of the American College of Cardiology from October 1, 2015, to October 1, 2016. A total of 345 articles were identified, with 687 first and last authors originating from ≥50 different countries. Overall, 17% of authors were women (20% of the first and 14% of the last authors). Overall, 86% of authors held a medical degree (MD) or equivalent, and 25% of those also held another advanced degree (PhD, MPH, and/or MBA). The proportion of authors with an advanced degree in addition to an MD/equivalent was higher among foreign graduates and international contributors as compared with American graduates (31% vs. 30% vs. 17%, respectively, p < 0.0001). Of US-based authors with an MD/equivalent, 67% were American medical graduates (AMGs) and 33% were FMGs. Women authors represented 11% of FMGs, 16% of AMGs, and 12% of international physicians as contributors (p = 0.23). Foreign graduates and international researchers contribute substantially to cardiology research in the US, but women authors remain under-represented. Copyright © 2018 Hellenic Society of Cardiology.

    Adult patient series have shown hand-held echocardiography (echo) units (HHE) to be accurate for rapid diagnosis and triage. This is the first study to evaluate the ability of HHE to inform decision making in outpatient pediatric cardiology. New pediatric cardiology patients in outpatient clinics staffed by six pediatric cardiologists (experience 1-17 years) were prospectively enrolled if an echocardiogram (echo) was ordered during their initial visit. After history and physical examination and before a standard echo, the cardiologists performed a bedside HHE examination (GE Vscan 1.7-3.8 MHz), documented findings, and made a clinical decision. Diagnoses and decisions based on HHE were compared with final management after the standard echo. The study enrolled 101 subjects (ages 9 days to 19 years). The cardiologists considered HHE imaging adequate for decision making for 80 of the 101 subjects. For 77 of the 80 subjects with acceptable HHE imaging (68/68 normal and 9/12 abnormal standard echoes), the HHE-based primary diagnoses and decisions agreed with the final management. The sensitivity of HHE was 75 % (95 % confidence interval [CI] 43-94 %) and the positive predictive value 100 % (95 % CI 66-100 %) for pediatric heart disease. The agreement between standard echocardiography and HHE imaging was substantial (κ = 0.82). Excluding one of the least experienced cardiologists, HHE provided the basis for correct cardiac diagnoses and management for all the subjects with acceptable HHE imaging (58/58 normal and 9/9 abnormal echoes). In outpatient pediatric cardiology, HHE has potential as a tool to complement physical examination. Further investigation is needed to evaluate how value improves with clinical experience.

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

    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.

    2002-01-01

    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

    Interventional cardiology has finally completed, after 26 years of advocacy, a professional hat trick: independent board certification, membership as a unique specialty in the American Medical Association House of Delegates (AMA HOD), and recognition by the Centers for Medicaid and Medicare Services (CMS) as a separate medical specialty. This article points out how these distinctions for interventional cardiology and its professional society, the Society for Cardiovascular Angiography and Interventions (SCAI), have led to clear and definite benefits for interventional cardiologists and their patients.

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

    International Nuclear Information System (INIS)

    2012-01-01

    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

    Full Text Available There is a growing need worldwide to take medical care to distant locations far from the main urban centers, particularly to rural areas. Furthermore, there is the ethical imperative to provide equal access to medical care to all patients, regardless of their place of residence, so as to satisfy an increasingly demanding population. A widespread problem, from which cardiology is not excepted, is the insufficient number of specialists and their uneven distribution. The upsurge in information and communications technology has made available a large collection of tools, mainly computers, smartphones, e-mail, and the Internet, to name just a few, to meet the needs of communication between individuals and organizations. This article defines telemedicine and describes its application in the practice of cardiology and its impact in Chile.

    Workforce experts predict a future shortage of cardiologists that is expected to impact rural areas more severely than urban areas. However, there is little research on how rural patients are currently served through clinical outreach. This study examines the impact of cardiology outreach in Iowa, a state with a large rural population, on participating cardiologists and on patient access. Outreach clinics are tracked annually in the Office of Statewide Clinical Education Programs Visiting Medical Consultant Database (University of Iowa Carver College of Medicine). Data from 2014 were analyzed. In 2014, an estimated 5460 visiting consultant clinic days were provided in 96 predominantly rural cities by 167 cardiologists from Iowa and adjoining states. Forty-five percent of Iowa cardiologists participated in rural outreach. Visiting cardiologists from Iowa and adjoining states drive an estimated 45 000 miles per month. Because of monthly outreach clinics, the average driving time to the nearest cardiologist falls from 42.2±20.0 to 14.7±11.0 minutes for rural Iowans. Cardiology outreach improves geographic access to office-based cardiology care for more than 1 million Iowans out of a total population of 3 million. Direct travel costs and opportunity costs associated with physician travel are estimated to be more than $2.1 million per year. Cardiologists in Iowa and adjoining states have expanded access to office-based cardiology care from 18 to 89 of the 99 counties in Iowa. In these 71 counties without a full-time cardiologist, visiting consultant clinics can accommodate more than 50% of office visits in the patients' home county. © 2016 The Authors.

    Cardiac e-consults may be an effective way to deliver value-oriented outpatient cardiology care in an accountable care organization. Initial results of cardiac e-consults have demonstrated high satisfaction among both patients and referring providers, no known adverse events, and low rates of diagnostic testing. Nevertheless, differences between e-consults and traditional consults, effects of e-consults on traditional consult volume, and whether patients seek traditional consults after e-consults are unknown. We established a cardiac e-consult program on January 13, 2014. We then conducted detailed medical record reviews of all patients with e-consults to detect any adverse clinical events and detect subsequent traditional visits to cardiologists. We also performed 2 comparisons. First, we compared age, gender, and referral reason for e-consults vs traditional consults. Second, we compared changes in volume of referrals to cardiology vs other medical specialties that did not have e-consults. From January 13 to December 31, 2014, 1,642 traditional referrals and 165 e-consults were requested. The proportion of e-consults of all evaluations requested over that period was 9.1%. Gender balance was similar among traditional consults and e-consults (44.8% male for e-consults vs 45.0% for traditional consults, P = .981). E-consult patients were younger than traditional consult patients (55.3 vs 60.4 years, P cardiology visit during the follow-up period. E-consults are an effective and safe mechanism to enhance value in outpatient cardiology care, with low rates of bounceback to traditional consults. E-consults can account for nearly one-tenth of total outpatient consultation volume at 1 year within an accountable care organization and are associated with a reduction in traditional referrals to cardiologists.

    In 2012, the American College of Cardiology's (ACC) Adult Congenital and Pediatric Cardiology Council established a program to develop quality metrics to guide ambulatory practices for pediatric cardiology. The council chose five areas on which to focus their efforts; chest pain, Kawasaki Disease, tetralogy of Fallot, transposition of the great arteries after arterial switch, and infection prevention. Here, we sought to describe the process, evaluation, and results of the Infection Prevention Committee's metric design process. The infection prevention metrics team consisted of 12 members from 11 institutions in North America. The group agreed to work on specific infection prevention topics including antibiotic prophylaxis for endocarditis, rheumatic fever, and asplenia/hyposplenism; influenza vaccination and respiratory syncytial virus prophylaxis (palivizumab); preoperative methods to reduce intraoperative infections; vaccinations after cardiopulmonary bypass; hand hygiene; and testing to identify splenic function in patients with heterotaxy. An extensive literature review was performed. When available, previously published guidelines were used fully in determining metrics. The committee chose eight metrics to submit to the ACC Quality Metric Expert Panel for review. Ultimately, metrics regarding hand hygiene and influenza vaccination recommendation for patients did not pass the RAND analysis. Both endocarditis prophylaxis metrics and the RSV/palivizumab metric passed the RAND analysis but fell out during the open comment period. Three metrics passed all analyses, including those for antibiotic prophylaxis in patients with heterotaxy/asplenia, for influenza vaccination compliance in healthcare personnel, and for adherence to recommended regimens of secondary prevention of rheumatic fever. The lack of convincing data to guide quality improvement initiatives in pediatric cardiology is widespread, particularly in infection prevention. Despite this, three metrics were

  15. Nuclear cardiology procedures to diagnose ischemia in coronary artery disease

    International Nuclear Information System (INIS)

    Kropp, J.

    1999-01-01

    Nuclear cardiology is equipped with a broad spectrum of diagnostic capabilities which allow the evaluation of ventricular performance, perfusion and metabolism of the heart. The principle of nuclear medicine procedures consists in the administration of free radioisotopes or radiopharmaceuticals to detect their spatial distribution within the body by detecting their y-rays from outside by gamma cameras. Myocardial perfusion scintigraphy is the most important procedure in nuclear cardiology and is performed on a routine basis with 201 Thallium-Chloride ( 201 Tl) since 1975. With the Single-Photon Emission Computerized Tomography (SPECT) technique it is possible to diagnose ischemia of the left ventricle on the basis of coronary artery disease with a sensitivity of 90-95% and a specificity of about 55%. Recently 99m Tc-tracers were developed for this purpose, which have many advantages due to their better physical properties, their easy handling and availability. The diagnostic accuracy is the same compared to ( 201 Tl). Free fatty acids labeled with 123 Iodine like 123 IPPA are alternative tracers to diagnose ischemia by the metabolic alteration and are pathognomonic tracers to diagnose the heart involvement in myopathies or metabolic defects related to fatty acid degradation which are the main fuel of the normal myocytes. Finally we should not forget the radionuclide ventriculography (RNVG) which is one of the oldest nuclear cardiology procedures providing us with very objective, reliable results of ventricular performance.

  16. Enabling Precision Cardiology Through Multiscale Biology and Systems Medicine

    Kipp W. Johnson, BS

    2017-06-01

    Full Text Available Summary: The traditional paradigm of cardiovascular disease research derives insight from large-scale, broadly inclusive clinical studies of well-characterized pathologies. These insights are then put into practice according to standardized clinical guidelines. However, stagnation in the development of new cardiovascular therapies and variability in therapeutic response implies that this paradigm is insufficient for reducing the cardiovascular disease burden. In this state-of-the-art review, we examine 3 interconnected ideas we put forth as key concepts for enabling a transition to precision cardiology: 1 precision characterization of cardiovascular disease with machine learning methods; 2 the application of network models of disease to embrace disease complexity; and 3 using insights from the previous 2 ideas to enable pharmacology and polypharmacology systems for more precise drug-to-patient matching and patient-disease stratification. We conclude by exploring the challenges of applying a precision approach to cardiology, which arise from a deficit of the required resources and infrastructure, and emerging evidence for the clinical effectiveness of this nascent approach.

    As part of the American College of Cardiology Adult Congenital and Pediatric Cardiology Section effort to develop quality metrics (QMs) for ambulatory pediatric practice, the chest pain subcommittee aimed to develop QMs for evaluation of chest pain. A group of 8 pediatric cardiologists formulated candidate QMs in the areas of history, physical examination, and testing. Consensus candidate QMs were submitted to an expert panel for scoring by the RAND-UCLA modified Delphi process. Recommended QMs were then available for open comments from all members. These QMs are intended for use in patients 5-18 years old, referred for initial evaluation of chest pain in an ambulatory pediatric cardiology clinic, with no known history of pediatric or congenital heart disease. A total of 10 candidate QMs were submitted; 2 were rejected by the expert panel, and 5 were removed after the open comment period. The 3 approved QMs included: (1) documentation of family history of cardiomyopathy, early coronary artery disease or sudden death, (2) performance of electrocardiogram in all patients, and (3) performance of an echocardiogram to evaluate coronary arteries in patients with exertional chest pain. Despite practice variation and limited prospective data, 3 QMs were approved, with measurable data points which may be extracted from the medical record. However, further prospective studies are necessary to define practice guidelines and to develop appropriate use criteria in this population. © 2017 Wiley Periodicals, Inc.

  18. Advanced Imaging of Intracranial Atherosclerosis: Lessons from Interventional Cardiology

    Directory of Open Access Journals (Sweden)

    2017-08-01

    Full Text Available Intracranial atherosclerosis is a major cause of ischemic stroke. Patients with a high degree of stenosis have a significant rate of stroke despite medical therapy. Two randomized trials of stenting have failed to show benefit. Improving periprocedural complication rates and patient selection may improve stenting outcomes. Fractional flow reserve (FFR, intravascular ultrasound (IVUS, and optical coherence tomography (OCT are intravascular imaging techniques employed to improve patient selection and stent placement in interventional cardiology. FFR has been shown to improve cardiovascular outcomes when used in patient selection for intervention. Studies of FFR in intracranial atherosclerosis show that the measure may predict which plaques lead to stroke. IVUS is used in cardiology to quantify stenosis and assist with stent placement. Comparisons with histology show that it can reliably characterize plaques. Several case reports of IVUS in intracranial arteries show the technique to be feasible and indicate it may improve stent placement. Plaque characteristics on IVUS may help identify vulnerable plaques. In interventional cardiology, OCT provides excellent visualization of vessel geometry and is useful periprocedurally. Images reliably identify thin-capped fibroatheromas and other plaque features. Case reports indicate that OCT is safe for use in intracranial arteries. OCT can be used to identify perforator vessels and so may be useful in avoiding perforator strokes, a common complication of stenting. Plaque characteristics on OCT may be useful in patient selection.

    Following the Safe and Sustainable review of Paediatric Services in 2012/2013, National Health Service England recommended that local paediatric cardiology services should be provided by specially trained paediatricians with expertise in cardiology in all non-specialist hospitals. To understand the variation in local paediatric cardiology services provided across district general hospitals in the United Kingdom. An internet-based questionnaire was sent out via the Paediatrician with Expertise in Cardiology Special Interest Group and the Neonatologists with Interest in Cardiology and Haemodynamics contact databases and the National Health Service directory. Non-responders were followed-up via telephone. The response rate was 80% (141 of 177 hospitals), and paediatricians with expertise in cardiology were available in 68% of those. Local cardiology clinics led by paediatricians with expertise in cardiology were provided in 96 hospitals (68%), whereas specialist outreach clinics were held in 123 centres (87%). A total of 11 hospitals provided neither specialist outreach clinics nor any local cardiology clinics led by paediatricians with expertise in cardiology. Paediatric echocardiography services were provided in 83% of the hospitals, 12-lead electrocardiogram in 96%, Holter electrocardiogram in 91%, and exercise testing in only 47% of the responding hospitals. Telemedicine facilities were established in only 52% of the centres, where sharing echocardiogram images via picture archiving and communication system was used most commonly. There has been a substantial increase in the availability of paediatricians with expertise in cardiology since 2008. Most of the hospitals are well-supported by specialist cardiology centres via outreach clinics; however, there remains significant variation in the local paediatric cardiology services provided across district general hospitals in the United Kingdom.

  1. Scatter radiation dose at height of the lens and image quality in interventional cardiology

    Leguees, Fernando A. Leyton

    2016-01-01

    Cardiologist and other staff members receive high doses of scattered radiation. Cases of radiation-induced cataract among cardiology professionals have been reported in studies, estimates for the dose to eye lens ranged from 450 to 900 mSv per year (without ceiling suspended screen), over several years. Recent surveys regarding high prevalence of lens changes likely induced by radiation exposure suggest an urgent need for improved radiation safety and training, use of eye protection during catheterization procedures, and improved occupational dosimetry. In view of the evidence of radiation injuries, the ICRP recommends limiting the radiation dose to the lens to 20 mSv per year for occupational exposure. A system for optimizing the radiation exposure is the measurement of entrance surface air kerma (K a,e ) and kerma-area product (P KA ) for patient and scattered dose or dose rate at the position for the staff, under clinical working conditions using phantoms and defined technical factors. Correlating K a,e and P KA with the scatter dose, applying the attenuation factors protective devices can enable estimation of the lens doses for operators. The purpose of this work is: to study the possibility of establishing a procedure which is useful for scientific societies and the regulatory authority in the prevention and control of IOE dose and to control and improve the quality of procedures in interventional cardiology as an initiative to raise awareness and optimization of radiological protection. Measurements were taken in different cardiac laboratories. Clinical working conditions were reproduced during the experiments for the different hemodynamic angiographic projections and operating modes used in fluoroscopy and cine. A first K a,e rate reference proposal for the characterization of angiography for the different acquisition modes were 16; 35; 40 and 220 (mGy/min), respectively. Considering the typical PKA values to patient in interventional cardiology procedures

    This study assessed the perceived usage of, and attitudes toward, communication technologies (mobile phone and texting, e-mail, and the World Wide Web) in patients attending a cardiology clinic with a view to guiding future health service redesign. This was performed in a remote regional hospital serving both urban and rural populations. A self-completion questionnaire was completed by a convenience sample of 221 patients attending a general cardiology clinic. The questions asked about patients' access to and use of technology at home. Data collected also included age, gender, travel time to the clinic, mode of travel, and whether the respondent was accompanied to the clinic. Appropriate statistical tests were used with significance taken at the 0.05 level. Age was the strongest predictor of use of communication technologies, with younger patients more likely to use e-mail, Web, mobile phone, and texting. However, frequency of use of e-mail was not related to age. It is encouraging that over 99% of patients used at least one communication technology. This study has highlighted that there may be several potential barriers to the widespread implementation of communication technologies in general cardiology patients. Cognizance should be taken of these findings when attempting service redesign.

    Sports cardiology is a new and rapidly evolving subspecialty. It aims to elucidate the cardiovascular effects of regular exercise and delineate its benefits and risks, so that safe guidance can be provided to all individuals engaging in sports and/or physical activity in order to attain the maximum potential benefit at the lowest possible risk. The European Society of Cardiology (ESC) advocates systematic preparticipation cardiovascular screening in an effort to identify competitive athletes at risk of exercise-related cardiovascular events and sudden cardiac death. However, the implementation of preparticipation screening is hindered because of lack of structured training and as a result lack of sufficient expertise in the field of sports cardiology. In 2008 the European Society of Cardiology published a core curriculum for the general cardiologist, in which sports cardiology was incorporated within the topic 'Rehabilitation and Exercise Physiology'. However, the exponential rise in knowledge and the growing demand for expertise in the field of sports cardiology dictates the need to systematically structure the knowledge base of sports cardiology into a detailed curriculum. We envisage that the curriculum would facilitate more uniform training and guideline implementation throughout Europe, and safeguard that evaluation and guidance of competitive athletes or individuals who wish to engage in leisure-time sports activities is performed by physicians with expertise in the field. The current manuscript provides a comprehensive curriculum for sports cardiology, which may serve as a framework upon which universities and national and international health authorities will develop the training, evaluation and accreditation in sports cardiology.

    Compared with other solid tumours in childhood, neuroblastomas show a marked tendency to metastasise to the skeleton. The differentiation of these lesions from inflammatory and other malignant bone lesions in this age group is often difficult. The radiological findings in ten patients with metastasing and histologically confirmed neuroblastomas have been reviewed and the typical appearances in the skeleton are described. The most important features in the differential diagnosies are discussed and the significance of bone changes in the diagnosis of neuroblastoma have been evaluated. (orig.) [de

    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.

    Systematic assessments of the scientific production can optimize resource allocation and increase research productivity in Brazil. The aim of this study was to evaluate the profile and scientific production of researchers in the field of Cardiology who have fellowship in Medicine provided by the Conselho Nacional de Desenvolvimento Científico e Tecnológico. The curriculum Lattes of 33 researchers with active fellowships from 2006 to 2008 were included in the analysis. The variables of interest were: gender, affiliation, tutoring of undergraduate, masters and PhD students, and scientific production and its impact. : There was predominance of males (72.7%) and of fellowship level 2 (56.4%). Three states of the Federation were responsible for 94% of the researchers: SP (28; 71.8%), RS (4; 10.3%), e RJ (3; 9.1%). Four institutions are responsible for about 82% of researchers: USP (13; 39.4%), UNESP (5; 15.2%), UFRGS (4; 12.1%) e UNIFESP (3; 9.1%). During all academic careers, the researchers published 2.958 journal articles, with a mean of 89 articles per researcher. Of total, 55% and 75% were indexed at Web of Science and Scopus databases, respectively. The researchers received a total of 19648 citations at the database Web of Science, with a median of 330 citations per researcher (IQ = 198-706). The average number of citations per article was 13.5 citations (SD = 11.6). Our study has shown that researchers in the field of cardiology have a relevant scientific production. The knowledge of the profile of researchers in the field of Cardiology will probably enable effective strategies to qualitatively improve the scientific output of Brazilian researchers.

    Typical, cavotricuspid-dependent atrial flutter is the most common atrial macroreentry tachycardia. The incidence of atrial flutter (typical and atypical forms) is age-dependent with 5/100,000 in patients less than 50 years and approximately 600/100,000 in subjects > 80 years of age. Concomitant heart failure or pulmonary disease further increases the risk of typical atrial flutter.Patients with atrial flutter may present with symptoms of palpitations, reduced exercise capacity, chest pain, or dyspnea. The risk of thromboembolism is probably similar to atrial fibrillation; therefore, the same antithrombotic prophylaxis is required in atrial flutter patients. Acutely symptomatic cases may be subjected to cardioversion or pharmacologic rate control to relieve symptoms. Catheter ablation of the cavotricuspid isthmus represents the primary choice in long-term therapy, associated with high procedural success (> 97 %) and low complication rates (0.5 %).This article represents the third part of a manuscript series designed to improve professional education in the field of cardiac electrophysiology. Mechanistic and clinical characteristics as well as management of isthmus-dependent atrial flutter are described in detail. Electrophysiological findings and catheter ablation of the arrhythmia are highlighted.

    In this article, we will provide a description of metabolomics in comparison with other, better known “omics” disciplines such as genomics and proteomics. In addition, we will review the current rationale for the implementation of metabolomics in cardiology, its basic methodology and the available data from human studies in this discipline. The topics covered will delineate the importance of being able to use the metabolomic information to understand the mechanisms of diseases from the perspective of systems biology, and as a non-invasive approach to the diagnosis, grading and treatment of cardiovascular diseases.

    Atrial fibrillation (AF) has a huge impact on clinical stroke because it is the primary cause of cardio-embolism, which constitutes ~20% of all strokes. As a result, there is a great need to explore safer and more effective primary and secondary prophylactic agents. In this article, we discuss the overlapping issues pertaining to AF from both a neurology and cardiology standpoint. We focus on the dynamic interplay of neurovascular and cardiovascular diseases in relation to AF, traditional and novel risk factors for AF leading to stroke, impact of AF on cognitive decline, and current upstream medical and surgical options for embolism prophylaxis.

    Training of postgraduate students has traditionally been done in person in a hospital setting with hands-on training with each faculty member imparting knowledge to 2 to 4 students per year. Supplementing their practical education with online instruction could make a significant difference in standardizing pediatric cardiology education in India. To present the rationale, methods and survey results of a live e-Teaching methodology implemented for Pediatric cardiology trainees in association with the National Board of Examinations, India. Between March 2010 and March 2014, 310 e-classes were conducted in the Pediatric cardiac sciences by 24 e-teachers. Content of the e-Learning program was based on a 2-year pediatric cardiology curriculum and included twice-weekly live online video training sessions, a library of recorded sessions and online test quizzes for the students. A total of 231 students accessed the program at various times over the 4-year period. In our study, requests for access to the e-lectures increased from 10/year the first year to 100/year by the fourth year with feedback surveys conveying a high satisfaction level from the students and a high need for this knowledge. The advantages of virtual live e-Learning included the fact that one teacher can teach multiple students in multiple geographic locations at the same time, obviating the issue of quality teacher shortage and the same content can be disseminated to all students undergoing specialist training so there is a national consensus on diagnostic and management approach among all trainees. Additionally, the e-classes can be recorded and replayed so they can be viewed repeatedly by the same group or new trainees. This is the first sustained use of e-Teaching in a medical super-specialty in India. We believe that e-Teaching is an innovative solution that can be applied, not just to Pediatric Cardiology as we have done, but to all branches of specialist and super-specialist medical training in

    Training requirements for general cardiologists without echocardiographic expertise to perform focused cardiac ultrasound (FCU) with portable devices have not yet been defined. The objective of this study was to evaluate a training program to instruct cardiology residents to perform FCU with a hand-carried device (HCD) in different clinical settings. Twelve cardiology residents were subjected to a 50-question test, 4 lectures on basic echocardiography and imaging interpretation, the supervised interpretation of 50 echocardiograms and performance of 30 exams using HCD. After this period, they repeated the written test and were administered a practical test comprising 30 exams each (360 patients) in different clinical settings. They reported on 15 parameters and a final diagnosis; their findings were compared to the HCD exam of a specialist in echocardiography. The proportion of correct answers on the theoretical test was higher after training (86%) than before (51%; P = 0.001). The agreement was substantial among the 15 parameters analyzed (kappa ranging from 0.615 to 0.891; P < 0.001). The percentage of correct interpretation was lower for abnormal (75%) than normal (95%) items, for valve abnormalities (85%) compared to other items (92%) and for graded scale (87%) than for dichotomous (95%) items (P < 0.0001, for all). For the final diagnoses, the kappa value was higher than 0.941 (P < 0.001; 95% CI [0.914, 0.955]). The training proposed enabled residents to perform FCU with HCD, and their findings were in good agreement with those of a cardiologist specialized in echocardiography. © 2015, Wiley Periodicals, Inc.

    The report of an imaging procedure is a critical component of an examination, being the final and often the only communication from the interpreting physician to the referring or treating physician. Very limited evidence and few recommendations or guidelines on reporting imaging studies are available; therefore, an European position statement on how to report nuclear cardiology might be useful. The current paper combines the limited existing evidence with expert consensus, previously published recommendations as well as current clinical practices. For all the applications discussed in this paper (myocardial perfusion, viability, innervation, and function as acquired by single photon emission computed tomography and positron emission tomography or hybrid imaging), headings cover laboratory and patient demographics, clinical indication, tracer administration and image acquisition, findings, and conclusion of the report. The statement also discusses recommended terminology in nuclear cardiology, image display, and preliminary reports. It is hoped that this statement may lead to more attention to create well-written and standardized nuclear cardiology reports and eventually lead to improved clinical outcome.

    The results are presented on the «current situation of the organisation, resources and activity in paediatric cardiology in Spain». It was promoted by the Spanish Society of Paediatric Cardiology and Congenital Heart disease. An analysis was carried out on the results obtained from a specifically designed questionnaire, prepared by the Spanish Society of Paediatric Cardiology and Congenital Heart disease, that was sent to all hospitals around the country that offer the speciality of paediatric cardiology. A total of 86 questionnaires were obtained, including 14 hospitals that perform cardiac surgery on children. A total of 190 paediatric cardiology consultants, 40 cardiac surgeons, and 27 middle grade doctors performing their paediatric residency (MIR program) were identified. All hospitals had adequate equipment to perform an optimal initial evaluation of any child with a possible cardiac abnormality, but only tertiary centres could perform complex diagnostic procedures, interventional cardiology, and cardiac surgery. In almost all units around the country, paediatric cardiology consultants were responsible for outpatient clinics and hospital admissions, whereas foetal cardiology units were still mainly managed by obstetricians. The number of diagnostic and therapeutic procedures was similar to those reported in the first survey, except for a slight decrease in the total number of closed cardiac surgery procedures, and a proportional increase in the number of therapeutic catheterisations. Paediatric Cardiology in Spain is performed by paediatric cardiology consultants that were trained initially as general paediatricians, and then completed a paediatric cardiology training period. Almost all units have adequate means for diagnosis and treatment. Efforts should be directed to create a national registry that would not only allow a prospective quantification of diagnostic and therapeutic procedures, but also focus on their clinical outcomes.

    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.

    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.

    Cardiovascular disease is the most common cause of death in Western countries. Physician adherence to guidelines is often suboptimal, resulting in impaired patient outcome and prognosis. Multiple studies have been conducted to evaluate patterns and the influencing factors of patient adherence, but little is known about factors influencing physician guideline adherence. This review aims to identify factors influencing physician guideline adherence relevant to cardiology and to provide insights and suggestions for future improvement. Physician adherence was measured as adherence to standard local medical practice and applicable guidelines. Female gender and older age had a negative effect on physician guideline adherence. In addition, independent of the type of heart disease, physicians without cardiologic specialization were linked to physician noncompliance. Also, guideline adherence in primary care centers was at a lower level compared to secondary or tertiary care centers. The importance of guideline adherence increases as patients age, and complex diseases and comorbidity arise. Appropriate resources and interventions, taking important factors for nonadherence in account, are necessary to improve guideline adoption and adherence in every level of the chain. This in turn should improve patient outcome.

    The Fellowship Program of the Department of Cardiology at Boston Children's Hospital seeks to train academically oriented leaders in clinical care and laboratory and clinical investigation of cardiovascular disease in the young. The core clinical fellowship involves 3 years in training, comprising 24 months of clinical rotations and 12 months of elective and research experience. Trainees have access to a vast array of research opportunities - clinical, basic, and translational. Clinical fellows interested in basic science may reverse the usual sequence and start their training in the laboratory, deferring clinical training for 1 or more years. An increasing number of clinical trainees apply to spend a fourth year as a senior fellow in one of the subspecialty areas of paediatric cardiology. From the founding of the Department to the present, we have maintained a fundamental and unwavering commitment to training and education in clinical care and research in basic science and clinical investigation, as well as to the training of outstanding young clinicians and investigators.

    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 Gycm 2 and 22.5 mSv for RFCA, and 32 Gycm 2 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)

    This work is based on a acquisition and pretreating Service of data and signals resulting from several types of functional explorations in cardiology. This Service, through a specialised phone-line, is connected to the Medical Centre of Informatic where the different treatments and on occasion the recording of data are carried out. This functions according to the Real Time Executive System and the clinical results are send back to the investigation unit. The main types of cardiologic analysis as studied by the system are envisaged: measure in real time of the cardiac output and analysis of the radiocardiogram, measure and display of the thoracic potentials, spectral analysis of the vectorcardiogram, quantitative cineangiocardiography and analysis of intracardiac pressures. This system is particularly interesting in that it may treat several processes which could ask for a great capacity of storing and an important calculus power, see for instance the study of thoracic potentials. This type of analysis could not be envisaged financially with isolated calculators. The set of results obtained enables us to investigate thoroughly and precisely the cardiac performance [fr

    Full Text Available Carlos S de la Calzada Department of Medicine, Universidad Complutense de Madrid, Madrid, SpainAbstract: It is well known that an expert clinician formulates a diagnostic hypothesis with little clinical data. In comparison, students have difficulties in doing so. The mental mechanism of diagnostic reasoning is almost unconscious and therefore difficult to teach. The purpose of this essay (devoted to 2nd-year medical students is to present an integrating framework to teach clinical reasoning in cardiology. By analyzing cardiology with a synthetic mind, it becomes apparent that although there are many diseases, the heart, as an organ, reacts to illness with only six basic responses. The clinical manifestations of heart diseases are the direct consequence of these cardiac responses. Considering the six cardiac responses framework, diagnostic reasoning is done in three overlapping steps. With the presented framework, the process of reasoning becomes more visual and needs less clinical data, resembling that of the expert clinician.Keywords: clinical deduction, diagnostic reasoning, education, teaching methods

    Nuclear cardiology has historically played an important role in detection of cardiovascular disease as well as risk statification. With the growth of molecular biology have come new therapeutic interventions and the requirement for new diagnostic imaging approaches. Noninvasive targeted radiotracer based as well as transporter gene imaging strategies are evolving to meet these new needs, but require the development of an interdisciplinary approach which focuses on molecular processes, as well as the pathogenesis and progression of disease. This progress has been made possible with the availability of transgenic animal models along with many technological advances. Future adaptations of the developing experimental procedures and instrumentations will allow for the smooth translation and application to clinical practice. This review is intended as a brief overview on the subject molecular imaging. Basic concepts and historical perspective of molecular imaging will be reviewed first, followed by description of current technology, and concluding with current applications in cardiology. The emphasis will be on the use of both single photon emission computed tomography (SPECT) and positron emission tomography (PET) radiotracers, although other imaging modalities will be also briefly discussed. The specific approaches presented here will include receptor-based and reporter gene imaging of natural and therapeutical angiogenesis

    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

    The aim of this study was to analyse the processes through which job, career and research-related choices are determined in Italian cardiology, focusing on characteristics such as productivity, gender and family. In June 1996, a questionnaire surveying individual and career-related data was mailed to all members (8000) of the Italian societies of cardiology. Returned questionnaires numbered 1715 (21.4% of the total mailed), 83% were completed by men and 17% by women. For both hospital and academic careers, advancement in rank was influenced by variables denoting productivity, family and individual characteristics. However, men and women showed slightly different patterns. Promotion to the upper ranks of the hierarchy was highly dependent upon time (once the effects of the covariates were eliminated). This situation is typical of the internal labour market, that is, in institutions in which staff members are ranked on a hierarchical scale according to formal criteria that are 'rigid' and institutionalized, partially sheltered from competition. Therefore, once a member has gained access to the bottom of the hierarchy, the professional career is 'pre-determined' and seniority has an appreciable influence on promotion decisions; in this context, women appear to be at a disadvantage.

    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.)

  15. 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.

    2015-12-01

    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.

    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)

    In this study, skin dosimetry of patients undergoing interventional cardiology procedures is presented. Three hospitals were included. Two methods were used for skin dosimetry-radiochromic dosimetry films and reconstruction of skin dose distribution based on examination protocol. Maximum skin doses (MSD) obtained from both methods were compared for 175 patients. For patients for whom the film MSD was >1 Gy, the reconstruction MSD differed from the film MSD in the range of ± 50 % for 83 % of patients. For remaining patients, the difference was higher and it was caused by longer fluoroscopy time. For 59 patients for whom the cumulative dose was known, the cumulative dose was compared with the film MSD. Skin dosimetry with radiochromic films is more accurate than the reconstruction method, but films do not include X-ray fields from lateral projections whilst reconstructions do. (authors)

    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.

    Heart diseases are one of the leading causes of death in Western Countries and tend to become chronic, lowering the quality of life of the patients and ending up in a massive cost for the Health Systems and the society. Thus, there is a growing interest in finding new technologies that would allow the physician to effectively treat and prevent cardiac illnesses. Metabolomics is one of the new “omics” sciences enabling creation of a photograph of the metabolic state of an individual exposed to different environmental factors and pathologies. This review analyzed the most recent literature about this technology and its application in cardiology in order to understand the metabolic shifts that occur even before the manifestation of these pathologies to find possible early predictive biomarkers. In this way, it could be possible to find better treatments, ameliorate the patient's quality of life, and lower the death rate. This technology seems to be so promising that several industries are trying to set up kits to immediately assess the metabolites variations in order to provide a faster diagnosis and the best treatment specific for that patient, offering a further step toward the path of the development of a tailored medicine.

    High-fidelity patient simulation (HFPS) has been used in medical education to bridge gaps in medical knowledge and clinical skills. Few studies have analyzed the impact of HFPS in subspecialty rotations for pediatric residents. We hypothesized that pediatric residents exposed to HFPS with a structured content curriculum would perform better on a case quiz than residents without exposure to HFPS. Prospective randomized controlled Tertiary-care free standing children's hospital During a cardiology rotation, senior pediatric residents completed an online pediatric cardiology curriculum and a cardiology quiz. After randomization into two groups, the study group participated in a fully debriefed HFPS session. The control group had no HFPS. Both groups completed a case quiz. Confidence surveys pre- and postsimulation were completed. From October 2010 through March 2013, 55 residents who rotated through the pediatric cardiology rotation were used in the final analysis (30 control, 25 in the study group). There was no significant difference between groups on the initial cardiology quiz. The study group scored higher on the case quiz compared with the control group (P = .024). Based on pre- and postsimulation questionnaires, residents' confidence in approaching a pediatric cardiology patient improved from an average Likert score of 5.1 to 7.5 (on scale of 0-10) (P cardiology rotation was feasible and well received. Our study suggests that simulation promotes increased confidence and may modestly improve clinical reasoning compared to traditional educational techniques. Targeted simulation sessions may readily be incorporated into pediatric subspecialty rotations. © 2014 Wiley Periodicals, Inc.

    The treatment of children with cardiac disease is one of the most prevalent and costly pediatric inpatient conditions. The design of inpatient medical services for children admitted to and discharged from noncritical cardiology care units, however, is undefined. North American Pediatric Cardiology Programs were surveyed to define noncritical cardiac care unit models in current practice. An online survey that explored institutional and functional domains for noncritical cardiac care unit was crafted. All questions were multi-choice with comment boxes for further explanation. The survey was distributed by email four times over a 5-month period. Most programs (n = 45, 60%) exist in free-standing children's hospitals. Most programs cohort cardiac patients on noncritical cardiac care units that are restricted to cardiac patients in 39 (54%) programs or restricted to cardiac and other subspecialty patients in 23 (32%) programs. The most common frontline providers are categorical pediatric residents (n = 58, 81%) and nurse practitioners (n = 48, 67%). However, nurse practitioners are autonomous providers in only 21 (29%) programs. Only 33% of programs use a postoperative fast-track protocol. When transitioning care to referring physicians, most programs (n = 53, 72%) use facsimile to deliver pertinent patient information. Twenty-two programs (31%) use email to transition care, and eighteen (25%) programs use verbal communication. Most programs exist in free-standing children's hospitals in which the noncritical cardiac care units are in some form restricted to cardiac patients. While nurse practitioners are used on most noncritical cardiac care units, they rarely function as autonomous providers. The majority of programs in this survey do not incorporate any postoperative fast-track protocols in their practice. Given the current era of focused handoffs within hospital systems, relatively few programs utilize verbal handoffs to the referring pediatric

    To review the number, characteristics and clinical management of suspected ACS patients admitted to cardiology and non-cardiology services at Auckland City Hospital, to assess differences between these services and to assess the number who would potentially be enrolled in the All New Zealand Acute Coronary Syndrome (ACS) Quality Improvement Programme (ANZACS-QI) database. Auckland City Hospital patient data was extracted from the Australia and New Zealand ACS 'SNAPSHOT' audit, performed over 14 days in May 2012. There were 121 suspected ACS admissions to Auckland City hospital during the audit period, with 45 (37%) patients directly managed by the cardiology service, and 76 (63%) patients cared for by non-cardiology services. Based on the subsequent discharge diagnosis, the cardiology service had more patients with definite ACS than the non-cardiology services; 27/45 (60%) compared to 16/76 (21%), difference (95%CI) 39% (22-56), P<0.0001). Cardiology ACS patients were more likely to undergo echocardiography; 15/27 (56%) compared to 2/16 (13%), difference 42% (18-68), P=0.0089), coronary angiography; 21/27 (78%) compared to 3/16 (19%), difference (95%CI) 59% (34-84), P=0.0003), coronary revascularisation; 18/27 (67%) compared to 3/16 (19%), difference (95%CI) 48% (22-74), P=0.004, and be discharged on two antiplatelet agents; 18/26 (69%) compared to 3/15 (20%), difference (95%CI) 49% (22-76), P=0.0036, or an ACEI/ARB; 20/26 (77%) compared to 5/15 (33%), difference (95%CI) 44% (15-72), P=0.0088. In patients with a discharge diagnosis of definite ACS, those managed by non-cardiology services were less likely to receive guideline-recommended investigations, and management, in this relatively small cohort study. About one-third of all ACS patients are managed by non-cardiology services and would not be recorded by the ANZACS-QI database.

    To show the different forms of radiological presentations of aspergilloma, emphasizing the importance of recognizing the atypical forms. The explorations of 11 patients with aspergilloma were examined retrospectively between 1993 and 1997. These patients were studied using conventional X-rays and computed tomography (CT): Typical and atypical radiological findings were observed. In two patients, who presented recurrent hemoptysis, a percutaneous installation of amphotericin B was carried out with tomographic control. Out of the 11 patients, two were female and nine male. In eight of the cases the radiological findings showed an intercavity injury with different evolutionary forms, while in three of the cases there was a progressive pleural swelling. In the two patients treated pertinaciously, no significant radiological changes were observed, however, neither of them showed hemoptysis again. The pleural swelling adjacent to the cavity and/or the swelling of the cavity wall are atypical radiological presentations of the aspergilloma, that can accompany or precede the appearance of this illness.

    Tree-structured methodology applied for the GISSI-PSICOLOGIA project, although performed in the framework of earliest GISSI studies, represents a powerful tool to analyze different aspects of cardiologic care. The GISSI-PSICOLOGIA project has delivered a novel methodology based on the joint application of psychometric tools and sophisticated statistical techniques. Its prospective use could allow building effective epidemiological models relevant to the prognosis of the cardiologic patient. The various features of the RECPAM method allow a versatile use in the framework of modern e-health projects. The study used the Cognitive Behavioral Assessment H Form (CBA-H) psychometrics scales. The potential for its future application in the framework of Italian cardiology is relevant and particularly indicated to assist planning of systems for integrated care and routine evaluation of the cardiologic patient.

    In medical care settings, mental health symptoms of depression and distress are associated with poor medical outcomes, yet they are often underrecognized. Authors sought to examine the effect of having immediate mental-health screening in the cardiology clinic. The Patient Health Questionnaire and the Impact of Event Scale were used to screen for depression and distress in 316 patients at an urban cardiology clinic. Because of poor follow-up rates, a psychiatrist was placed on the premises of the cardiology clinic to facilitate referrals. Placing a psychiatrist within the cardiology clinic significantly improved the rate of successful referrals. Because 45 patients (14%) endorsed suicidal thoughts, authors conclude that mental health screening programs should include an immediate evaluation by a clinician.

    Many advances have been made in the field of nuclear cardiology in the past decade for enhancing the diagnostic and prognostic value of stress myocardial variability using SPECT technology. Gated SPECT for determining regional and global function have provided incremental diagnostic and prognostic information in the evaluation of patients with suspected or known coronary artery disease. Left ventricular ejection fraction and regional myocardial wall thickening can now be simultaneously evaluated with regional perfusion particularly with the use of the 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 201 Tl or with one of the 99m Tc-labeled imaging agents, or PET imaging with 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

    The objective of this work is to assess the occupational dose in interventional cardiology in a large hospital in Belgrade, Serbia. A double-dosimetry method was applied for the estimation of whole-body dose, using thermoluminescent dosemeters, calibrated in terms of the personal dose equivalent H p (10). Besides the double-dosimetry method, eye dose was also estimated by means of measuring ambient dose equivalent, H*(10), and doses per procedure were reported. Doses were assessed for 13 physicians, 6 nurses and 10 radiographers, for 2 consequent years. The maximum annual effective dose assessed was 4.3, 2.1 and 1.3 mSv for physicians, nurses and radiographers, respectively. The maximum doses recorded by the dosemeter worn at the collar level (over the apron) were 16.8, 11.9 and 4.5 mSv, respectively. This value was used for the eye lens dose assessment. Estimated doses are in accordance with or higher than annual dose limits for the occupational exposure. (authors)

    The aim of this work is to determine current radiographic protocols in paediatric interventional cardiology (IC) in the UK and Ireland. To do this we investigated which imaging parameters/protocols are commonly used in IC in different hospitals, to identify if a standard technique is used and illustrate any variation in practice. A questionnaire was sent to all hospitals in the UK and Ireland which perform paediatric IC to obtain information on techniques used in each clinical department and on the range of clinical examinations performed. Ethical and research governance approval was sought from the Office for Research Ethics Committees Northern Ireland and the individual trusts. A response rate of 79% was achieved, and a wide variation in technique was found between hospitals. The main differences in technique involved variations in the use of an anti-scatter grid and the use of additional filtration to the radiation beam, frame rates for digital acquisition and pre-programmed projections/paediatric specific programming in the equipment. We conclude that there is no standard protocol for carrying out paediatric IC in the UK or Ireland. Each hospital carries out the IC procedure according to its own local protocols resulting in a wide variation in radiation dose. (paper)

  15. [Cardiology was born with the modern medical science].

    Modern medical science was born in the post-Renaissance age and began to consolidate towards the middle of the XVII century thanks to physicists, physiologists and biologists, most of whom were direct or indirect pupils of Galileo. The discovery of blood circulation by Harvey is now considered the only progress in physiology at the beginning of the XVII century, comparable to the current advances seen in physical sciences. The history of this exploit could be written from view point of the progressive advance in knowledge. In his experiments, Harvey referred to the authentic not imaginary experiments, and put forward irrefutable quantitative arguments. We can therefore claim that his discovery of blood circulation was the first proper explanation of an organic process and the starting point leading to experimental physiology. So it seems justified to assert that modern medical science did not all rise suddenly, but was gradually structured starting from the middle of the XVII century following the path traced by William Harvey in light of Galileo's thought.

    Nutrition is one of the foundations of cardiovascular guidelines for risk reduction and treatment. However, little is known about whether cardiologists, cardiology fellows-in-training, and cardiovascular team members have the nutrition education and knowledge necessary to implement these guidelines. The aim of this study was to describe the educational experiences, attitudes, and practices relating to nutrition among cardiovascular professionals. Surveys completed by cardiologists, fellows-in-training, and cardiovascular team members inquired about their personal dietary habits, history of nutrition education, and attitudes regarding nutrition interventions. A total of 930 surveys were completed. Among cardiologists, 90% reported receiving no or minimal nutrition education during fellowship training, 59% reported no nutrition education during internal medicine training, and 31% reported receiving no nutrition education in medical school. Among cardiologists, 8% described themselves as having "expert" nutrition knowledge. Nevertheless, fully 95% of cardiologists believe that their role includes personally providing patients with at least basic nutrition information. The percentage of respondents who ate ≥5 servings of vegetables and fruits per day was: 20% (cardiologists), 21% (fellows-in-training), and 26% (cardiovascular team members). A large proportion of cardiovascular specialists have received minimal medical education and training in nutrition, and current trainees continue to experience significant education and training gaps.

    2018-04-12

    Systemic inflammatory response syndrome (SIRS), initially reported after cardiovascular surgery, has been described after various interventional cardiology procedures, including endovascular/thoracic aortic repair (EVAR/TEVAR), implantation of heart rhythm devices, percutaneous coronary intervention (PCI), electrophysiology procedures (EP), and transcatheter aortic valve implantation (TAVI). In these settings, a comprehensive understanding of the triggers, pathogenesis as well as a common diagnostic/therapeutic algorithm is lacking and will be discussed in this review. SIRS occurs in about 40% and 50% of patients undergoing TEVAR/EVAR and TAVI respectively; it affects 0.1% of patients undergoing implantation of heart rhythm devices. Prevalence is unknown after PCI or EP. Clinical presentation includes fever, dyspnoea/tachypnoea, tachycardia, weakness, chest pain and pericardial/pleural effusion. Several triggers can be identified, related to implanted devices, biomaterial, and procedural aspects (prolonged hypotension, aneurysm thrombus manipulation, active fixation atrial leads, coronary microembolization, balloon dilatation/stent implantantation, contrast medium, coronary/myocardial microperforation). Nonetheless, these triggers share three main pathogenic pathways leading to SIRS clinical manifestations: leucocytes activation, endothelial injury/activation, and myocardial/pericardial injury. Therapy consists of non-steroidal agents, with corticosteroids as second-line treatment in non-responders. Although a benign evolution is reported after implantation of heart rhythm devices, PCI and EP, major adverse events may occur after EVAR/TEVAR and TAVI at short- and mid-term follow up.

    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

    The aim of this work is to determine current radiographic protocols in paediatric interventional cardiology (IC) in the UK and Ireland. To do this we investigated which imaging parameters/protocols are commonly used in IC in different hospitals, to identify if a standard technique is used and illustrate any variation in practice. A questionnaire was sent to all hospitals in the UK and Ireland which perform paediatric IC to obtain information on techniques used in each clinical department and on the range of clinical examinations performed. Ethical and research governance approval was sought from the Office for Research Ethics Committees Northern Ireland and the individual trusts. A response rate of 79% was achieved, and a wide variation in technique was found between hospitals. The main differences in technique involved variations in the use of an anti-scatter grid and the use of additional filtration to the radiation beam, frame rates for digital acquisition and pre-programmed projections/paediatric specific programming in the equipment. We conclude that there is no standard protocol for carrying out paediatric IC in the UK or Ireland. Each hospital carries out the IC procedure according to its own local protocols resulting in a wide variation in radiation dose.

    At present the most widely used element in isotopic cardiology is undoubtedly 201 Tl. 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 201 Tl, then describes the techniques and apparatus used. The production, dosimetry, toxicity and biological behaviour of 201 Tl 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 201 Tl 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 [fr

    New European regulation regarding radiological protection of workers and more specifically the new occupational dose limit for the eye lens recently reduced to 20 mSv yr −1 may affect interventional cardiologists. This paper presents a set of measurements of occupational doses performed in five interventional cardiology centres and then compared with the new dose limit. The measurement of occupational doses was performed over the apron at chest level using electronic dosemeters recording H p (10). In one of the centres, scatter dose at goggles was also measured with optically stimulated luminescence dosemeters calibrated in terms of H p (0.07). An average H p (10) over the apron of 46 μSv/procedure was measured for cardiologists. Lower doses were noted in other professionals like second cardiologists, nurses or anaesthetists. Procedures for valvular and other structural heart diseases involved the highest occupational doses, averaging over 100 μSv/procedure. Important differences in occupational doses among centres may be indicative of different radiation protection habits. The new occupational dose limit for the eye lens is likely to be exceeded by those among the interventionalists who do not use protection tools (ceiling suspended screen and/or goggles) even with standard workloads.

  2. Cardiological-interventional therapy of coronary artery disease today

    1999-01-01

    The current importance of the interventional therapy of coronary artery disease may be deduced from the exponential increase in procedures performed in Germany in the last decade - at least 125,840 in 1996. Today, by improved catheter and balloon materials as well as by growing experience of the cardiologists, even complex lesions may be treated. Limitations of balloon angioplasty include acute vessel closure and restenosis - newer angioplasty devices like directional or rotational atherectomy or excimer-laser angioplasty did not overcome these limitations; only by coronary stenting, acute vessel closure could be managed and the likelihood of restenosis - at least in particular groups of patients - could be reduced. For a few years, intracoronary brachytherapy of the segments dilated with beta- or gamma-emitters has been seeking to reduce restenosis rate; the department of cardiology of the Dresden Cardiovascular Institute is participating in such a multicentre study using the beta-emitter 188 renium. Further main topics of our department represent primary angioplasty in patients with acute myocardial infarction and invasive diagnostic or interventional procedures by the transradial approach.

    Objective was to describe the clinical features of 5 patients with rare atypical presentation of idiopathic intracranial hypertension (IIH), and propose the possible mechanism of this atypical presentation. We carried out a retrospective study of 5 patients, admitted at King Khalid National Guard Hospital, Jeddah, Kingdom of Saudi Arabia with IIH during the period from January 2001 to December 2005. All were females with their age ranges from 24 to 40 years. The clinical presentations, the laboratory and imaging studies were analyzed. The opening pressures of the lumbar puncture tests were documented. All patients were presented with headache. One had typical pain of trigeminal neuralgia and one with neck pain and radiculopathy. Facial diplegia was present in one patient and two patients had bilateral 6th cranial neuropathy. Papilledema was present in all patients except in one patient. Imaging study was normal in all patients, and they had a very high opening pressure during lumbar puncture, except in one patient. All patients achieved full recovery with medical therapy in 6 to 12 weeks with no relapse during the mean follow up of 2 years. Atypical finding in IIH are rare and require a high index of suspicion for early diagnosis. (author)

    Background Transcatheter aortic valve implantation (TAVI) continues to gain popularity in the management of patients with severe aortic stenosis (SAS). Distribution of resources to maximise appropriate use remains a priority. Design & methods To determine the current perceptions and behaviours regarding SAS patient management, an 18-point multiple-choice questionnaire was distributed to European Society of Cardiology (ESC) Council for Cardiology Practice (CCP) e-journal and/or electronic newsletter subscribers. Respondents to all questions were considered. Sub-analyses based on respondent age, practice setting and geographical location were performed. Results Of 1245 full respondents, 41.5% were aged ≥ 51 years, 22.7% were aged 41-50 years and 35.8% were aged ≤ 40 years. The majority were located in Europe (77.5%), followed by Asia/Oceania (11.6%), America (7.6%) and Africa (3.4%). In-hospital and out-of-hospital cardiologists accounted for 57.4% of and 28.5% of the sample, respectively, with the remainder being general practitioners/other. The majority of respondents (70.1%) claimed to diagnose between one and five cases of SAS per month. Free access to TAVI was reported by 41.2%, being less common for those aged ≤ 40 years (32.7%; p < 0.001), those located in Asia/Oceania, America and Africa (20.1%, 18.1% and 2.4%, respectively; p < 0.01 in each case) and in-hospital compared to out-of-hospital cardiologists (35.7% vs. 54.5%, respectively; p < 0.001). The most common reason for not referring a patient for an aortic valve intervention was assessment that the patient was high risk/non-operable (55.5%), followed by short life expectancy (30.5%). The most common reason for referring a patient for TAVI over surgical replacement was surgical risk score (56.9%). The most commonly perceived main complication of TAVI was stroke (28.9%), while the most frequently selected main benefit was improvement in quality of life (37.2%). A high

    Full Text Available This study examined the effect of two sources of memory error: exposure to post-event information and extracting typical contents from schemata. Participants were shown a video of a bank robbery and presented with highand low-typicality misinformation extracted from two normative studies. The misleading suggestions consisted of either changes in the original video information or additions of completely new contents. In the subsequent recognition task the post-event misinformation produced memory impairment. The participants used the underlying schema of the event to extract high-typicality information which had become integrated with episodic information, thus giving rise to more hits and false alarms for these items. However, the effect of exposure to misinformation was greater on low-typicality items. There were no differences between changed or added information, but there were more false alarms when a low-typicality item was changed to a high-typicality item

    Graphical displays play a pivotal role in understanding data sets and disseminating results. For meta-analysis, they are instrumental in presenting findings from multiple studies. This report presents guidance to authors wishing to submit graphical displays as part of their meta-analysis to a clinical cardiology journal, such as HeartWhen using graphical displays for meta-analysis, we recommend the following: Use a flow diagram to describe the number of studies returned from the initial search, the inclusion/exclusion criteria applied and the final number of studies used in the meta-analysis.Present results from the meta-analysis using a figure that incorporates a forest plot and underlying (tabulated) statistics, including test for heterogeneity.Use displays such as funnel plot (minimum 10 studies) and Galbraith plot to visually present distribution of effect sizes or associations in order to evaluate small-study effects and publication bias).For meta-regression, the bubble plot is a useful display for assessing associations by study-level factors.Final checks on graphs, such as appropriate use of axis scale, line pattern, text size and graph resolution, should always be performed.

    To evaluate postgraduate training period, social life and problems of cardiology residents in Turkey by using a questionnaire form and to compare with the core curriculum of European Society of Cardiology for general cardiology. Overall, 529 residents of cardiology ages in range of 24-35 years (mean age: 26.5±2.0 years, 81.4% male) participated as volunteers in this cross-sectional survey study. An 86-item questionnaire form was used to evaluate the education process, capacity of knowledge and skill and social effectiveness level of participants. The questionnaire were composed both closed- and open-ended questions. The questionnaire form was filled in with the face-to-face communication method. The data of survey were compared with the core curriculum of European Society of Cardiology for general cardiology training period. Chi-square or Fischer exact test was used for statistical analysis. The participants were working in various university hospitals (70.3%) and training-research (state) hospitals in 31 different provinces in Turkey (40.8% in Marmara region). They visited 40±10 outpatients and 10±5 hospitalized pts daily in the clinics. The 3-5 residents worked at the clinic on night shifts and mostly (89%) 8 or more night shifts per month were held in their first training years. During first three-years of training 76% of residents have performed echocardiography, 40.8%-transesophageal echocardiography and 10% - intraoperative echocardiography. The 84.3% of them evaluated exercise tests, 76.4%-Holter electrocardiography and 53.3%-tilt-table tests. The rate of residents working in coronary angiography laboratories was 54.3%. The 53.7% of residents performed coronary angiography and 64%-only in the 4th year of their training. The number of coronary angiography performance was under expected when compared with European Society of Cardiology curriculum. The 18.5% of residents were participated as assistant researcher in an international multi-center study and

    Women are less present on the labor market and many studies have demonstrated the existence of gender differences regarding the participation rate and career advancement of women. The processes through which job-, career- and research-related choices are structured within the realm of Italian cardiology is described in this study, emphasizing the effects of productivity, gender and family commitments. In June of 1996, a questionnaire was mailed to all members of the Italian societies of cardiology. It included mainly (pre-coded) set-choice questions concerning individual characteristics, career-related data and information pertaining to teaching, scientific and research activity. Returned questionnaires numbered 1715 (21.4% of the total mailed), with 83% completed by males and 17% by females. For both hospital and academic careers, advancement in rank was influenced by variables denoting productivity, family and individual characteristics. Promotion to the upper ranks of the hierarchy was highly dependent upon time (once the effects of the covariates were eliminated). This is a situation that is typical of the internal labor market or in other words, of an institution in which staff members are ranked on a hierarchical scale according to formal criteria that are "rigid" and institutionalized, partially or totally sheltered from competition. Therefore, once a member has gained access to the first level of the hierarchy, his/her professional career is pre-determined to a certain extent and seniority ends up taking on importance in promotion decisions to an appreciable extent; in this field, the weight of seniority on promotion ranges between 30 and 50%.

    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. Copyright © 2012 American College of Cardiology Foundation. Published by Elsevier Inc.

    2005-01-01

    As in previous years, the year 2003 was notable for clinical studies confirming the position occupied by Nuclear Cardiology and MRI in patient management. This was confirmed in the different areas tackled this year. In myocardial ischaemia, 2 points attracted our attention. Firstly, there is the good prognostic value of a normal myocardial perfusion (stress) CT with tetrofosmin (Myoview), which makes the good prognostic value of a normal SPECT independent of the type of tracer used ( 201 Tl, 99m Tc - MIBI, 99m Tc - Tetrofosmine). Secondly, an elegant study performed in 10627 patients, once more confirming the significance of using stress SPECT in the therapeutic strategy (medical treatment versus revascularization). Furthermore, in the area of myocardial infarction (MI), 3 points attracted our attention : the use of Annexin A5 - 99m Tc was advantageous for visualizing apoptosis in the territory at risk, the limits of studying regional myocardial function versus contrast MRI in the diagnosis of MI, and the good sensitivity of contrast MRI in the detection of sub-endocardial MI. In the diagnosis of acute coronary syndrome, one study reported the sensitivity and specificity of emergency MRI (84 versus 85%). In the area of myocardial viability, one study reported the inferiority of electromechanical mapping compared to SPECT and positron emission tomography. In the area of post-infarct cardiac failure, studies have confirmed the place of LVEF in the evaluation of prognosis, and combining this with BNP and possibly the study of the angiotensin converting enzyme gene. Similarly another study reported the superiority of MIBG-1231 compared to cardiac frequency variability in the evaluation of prognosis. (author)

    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

    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 cardiology is lower and the average quality score is higher than in the RoW. There is regional variation in effective dose in relation to the best practice quality score. A possible reason for the differences between Europe and the RoW could be the safety culture fostered by actions under the Euratom directives and the implementation of diagnostic reference levels. Stress-only imaging and weight-adjusted activity might be targets for optimization of European nuclear cardiology practice.

    Full Text Available A pitiose eqüina é doença endêmica no Pantanal Brasileiro e causa prejuízos significativos a eqüinocultura. Neste trabalho são relatados 16 casos de pitiose subcutânea em eqüinos no Pantanal Sul-Matogrossense, que foram divididos em onze casos típicos e cinco casos atípicos, de acordo com o quadro clínico e o tempo de duração das lesões. O diagnóstico foi confirmado pela detecção de anticorpos específicos pelo teste ELISA, isolamento do agente e histopato-lógico. A duração da doença variou entre 1 e 6 meses nos casos típicos e superior a 12 meses nos casos atípicos. As lesões dos casos típicos caracterizavam-se por granulomas subcutâneos, ulcerados, com abundante secreção serossangui-nolenta e prurido. Nos casos atípicos foram observadas lesões subcutâneas caracterizadas por grandes massas "tumorais" circunscritas, recobertas por pele escura, sem ulcerações e com pouca secreção. Os animais estavam em bom estado nutricional e as lesões apresentavam-se de aspecto organizado, às vezes pedunculadas. Histologicamente, foi observado tecido de granulação com muitos eosinófilos nos casos típicos, enquanto os atípicos, se caracterizaram por hiperplasia pseudo-epiteliomatosa da epiderme e infiltrado eosinofílico.

    There is growing concern about radiation exposure from nuclear myocardial perfusion imaging (MPI), particularly among younger patients who are more prone to develop untoward effects of ionizing radiation, and hence US and European professional society guidelines recommend age as a consideration in weighing radiation risk from MPI. We aimed to determine how patient radiation doses from MPI vary across age groups in a large contemporary international cohort. Data were collected as part of a global cross-sectional study of centers performing MPI coordinated by the International Atomic Energy Agency (IAEA). Sites provided information on each MPI study completed during a single week in March-April 2013. We compared across age groups laboratory adherence to pre-specified radiation-related best practices, radiation effective dose (ED; a whole-body measure reflecting the amount of radiation to each organ and its relative sensitivity to radiation's deleterious effects), and the proportion of patients with ED ≤ 9 mSv, a target level specified in guidelines. Among 7911 patients undergoing MPI in 308 laboratories in 65 countries, mean ED was 10.0 ± 4.5 mSv with slightly higher exposure among younger age groups (trend p value < 0.001). There was no difference in the proportion of patients with ED ≤ 9 mSv across age groups, or in adherence to best practices based on the median age of patients in a laboratory. In contemporary nuclear cardiology practice, the age of the patient appears not to impact protocol selection and radiation dose, contrary to professional society guidelines. Copyright © 2018.

    Objectives The relationship between preoperative medical consultations and postoperative complications has not been extensively studied. Thus, we investigated the impact of preoperative consultation on postoperative morbidity following elective abdominal aortic aneurysm repair. Methods A retrospective review was conducted on 469 patients (mean age 72 years, 20% female) who underwent elective abdominal aortic aneurysm repair from June 2007 to July 2014. Data elements included detailed medical history, preoperative cardiology consultation, and postoperative complications. Primary outcomes included 30-day morbidity, consult-specific morbidity, and mortality. A bivariate probit regression model accounting for the endogeneity of binary preoperative medical consult and patient variability was estimated with a maximum likelihood function. Results Eighty patients had preoperative medical consults (85% cardiology); thus, our analysis focuses on the effect of cardiac-related preoperative consults. Hyperlipidemia, increased aneurysm size, and increased revised cardiac risk index increased likelihood of referral to cardiology preoperatively. Surgery type (endovascular versus open repair) was not significant in development of postoperative complications when controlling for revised cardiac risk index ( p = 0.295). After controlling for patient comorbidities, there was no difference in postoperative cardiac-related complications between patients who did and did not undergo cardiology consultation preoperatively ( p = 0.386). Conclusions When controlling for patient disease severity using revised cardiac risk index risk stratification, preoperative cardiology consultation is not associated with postoperative cardiac morbidity.

    Background/Objectives: The specific credentials and continuing education (CME/CE) of nuclear cardiology laboratory medical and technical staff are important factors in the delivery of quality imaging services that have not been systematically evaluated. Methods: Nuclear cardiology accreditation application data from the Intersocietal Accreditation Commission (IAC) was used to characterize facilities performing myocardial perfusion imaging by setting, size, previous accreditation and credentials of the medical and technical staff. Credentials and CME/CE were compared against initial accreditation decisions (grant or delay) using multivariable logistic regression. Results: Complete data were available for 1913 nuclear cardiology laboratories from 2011-2014. Laboratories with initial positive accreditation decisions had a greater prevalence of Certification Board in Nuclear Cardiology (CBNC) certified medical directors and specialty credentialed technical directors. Certification and credentials of the medical and technical directors, respectively, staff CME/CE compliance, and assistance of a consultant with the application were positively associated with accreditation decisions. Conclusion: Nuclear cardiology laboratories directed by CBNC-certified physicians and NCT- or PET-credentialed technologists were less likely to receive delay decisions for MPI. CME/CE compliance of both the medical and technical directors was associated with accreditation decision. Medical and technical directors' years of experience were not associated with accreditation decision. Copyright © 2017 by the Society of Nuclear Medicine and Molecular Imaging, Inc.

  17. Prediction and typicality in multiverse cosmology

    2014-01-01

    In the absence of a fundamental theory that precisely predicts values for observable parameters, anthropic reasoning attempts to constrain probability distributions over those parameters in order to facilitate the extraction of testable predictions. The utility of this approach has been vigorously debated of late, particularly in light of theories that claim we live in a multiverse, where parameters may take differing values in regions lying outside our observable horizon. Within this cosmological framework, we investigate the efficacy of top-down anthropic reasoning based on the weak anthropic principle. We argue contrary to recent claims that it is not clear one can either dispense with notions of typicality altogether or presume typicality, in comparing resulting probability distributions with observations. We show in a concrete, top-down setting related to dark matter, that assumptions about typicality can dramatically affect predictions, thereby providing a guide to how errors in reasoning regarding typicality translate to errors in the assessment of predictive power. We conjecture that this dependence on typicality is an integral feature of anthropic reasoning in broader cosmological contexts, and argue in favour of the explicit inclusion of measures of typicality in schemes invoking anthropic reasoning, with a view to extracting predictions from multiverse scenarios.

    Full Text Available This study is devoted to the estimation of effective dose for children undergoing interventional cardiology examinations. The conversion coefficients (CC from directly measured dose area product (DAP value to effective dose (ED were calculated within the approved effective dose assessment methodology (Guidelines 2.6.1. 2944-11. The CC, Ed K , [mSv / (Gy • cm2] for newborn infants and children of 1, 5, 10 and 15 years old (main(range were calculated as 2.5 (1.8-3.2; 1.1 (0.8-1.3; 0.6 (0.4-0.7; 0.4 (0.3-0.5; and 0,22 (0,18-0,30 respectively. A special Finnish computer program PCXMC 2.0 was used for calculating the dose CC. The series of calculations were made for different values of the physical and geometrical parameters based on their real-existing range of values. The value of CC from DAP to ED were calculated for all pediatric age groups. This work included 153 pediatric interventional studies carried out in two hospitals of the city of St. Petersburg for the period of one year from the summer of 2015. The dose CC dependency from the patient’s age and parameters of the examinations were under the study. The dependence from the beam quality (filtration and tube voltage and age of the patient were found. The younger is the patient, stronger is the filtration and higher is the voltage, the higher is the CC value. The CC in the younger (newborn and older (15 years age groups are different by the factor of 10. It was shown that the changes of the geometric parameters (in the scope of their real existing range have small effect on the value of the effective dose, not exceed 30-50% allowable for radiation protection purpose. The real values of effective doses of children undergoing cardiac interventions were estimated. In severe cases, the values of ED can reach several tens of mSv.

    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.

    Cardiovascular services are the third largest source of Medicare spending. We examined the rate of cardiovascular service utilization in the community of Glendale, CA, compared with the nearest academic medical center, the University of Southern California. Publicly available utilization data released by Medicare for the years 2012 and 2013 were used to identify all inpatient and outpatient cardiology services provided in each practice setting. The analysis included 19 private and 17 academic cardiologists. In unadjusted analysis, academic physicians performed half as many services per Medicare beneficiary per year as those in private practice: 2.3 versus 4.8, p cardiology practice settings in southern California, medical service utilization per Medicare beneficiary was nearly 2-fold higher in private practice than in the academic setting, suggesting that there may be opportunity for substantially reducing costs of cardiology care in the community setting.

    2017-12-01

    The field of nuclear cardiology has changed considerably over recent years, with greater attention paid to safety and radiation protection issues. The wider usage of technetium-99m (Tc-99m)-labeled radiopharmaceuticals for single-photon emission computed tomography (SPECT) imaging using gamma cameras has contributed to better quality studies and lower radiation exposure to patients. Increased availability of tracers and scanners for positron emission tomography (PET) will help further improve the quality of studies and quantify myocardial blood flow and myocardial flow reserve, thus enhancing the contribution of non-invasive imaging to the management of coronary artery disease. The introduction of new instrumentation such as solid state cameras and new software will help reduce further radiation exposure to patients undergoing nuclear cardiology studies. Results from recent studies, focused on assessing the relationship between best practices and radiation risk, provide useful insights on simple measures to improve the safety of nuclear cardiology studies without compromising the quality of results.

  6. Decision Making in Paediatric Cardiology. Are We Prone to Heuristics, Biases and Traps?

    Hidden traps in decision making have been long recognised in the behavioural economics community. Yet we spend very limited, if any time, analysing our decision-making processes in medicine and paediatric cardiology. Systems 1 and 2 thought processes differentiate between rapid emotional thoughts and slow deliberate rational thoughts. For fairly clear cut medical decisions, in-depth analysis may not be needed, but in our field of paediatric cardiology it is not uncommon for challenging cases and occasionally 'simple' cases to generate significant debate and uncertainty as to the best decision. Although morbidity and mortality meetings frequently highlight poor outcomes for our patients, they often neglect to analyse the process of thought which underlined those decisions taken. This article attempts to review commonly acknowledged traps in decision making in the behavioural economics world to ascertain whether these heuristics translate to decision making in the paediatric cardiology environment. We also discuss potential individual and collective solutions to pitfalls in decision making.

    Gastroenterology and cardiology services are common and costly among Medicare beneficiaries. Episode-based payment, which aims to create incentives for high-quality, low-cost care, has been identified as a promising alternative payment model. This article describes research related to the design of episode-based payment models for ambulatory gastroenterology and cardiology services for possible testing by the Center for Medicare and Medicaid Innovation at the Centers for Medicare and Medicaid Services (CMS). The authors analyzed Medicare claims data to describe the frequency and characteristics of gastroenterology and cardiology index procedures, the practices that delivered index procedures, and the patients that received index procedures. The results of these analyses can help inform CMS decisions about the definition of episodes in an episode-based payment model; payment adjustments for service setting, multiple procedures, or other factors; and eligibility for the payment model.

    The purpose of this paper is lo report incidental findings of uptake of Tc99m-MIBI in anterior chest in a patient evaluated for a typical chest pain. A retrospective data collection was performed through chart review of the patient, a 67 year-old women, who had atypical chest pain with cardiac risk factors (hypertension, obesity, hypercholesterolemia, diabetes) with history of left total mastectomy (1995) without adjuvant chemotherapy and negative follow-up. Myocardial Perfusion imaging with Tc99m-MIBI was normal and showed uptake in anterior left chest in sagital views, described as suspected recurrent breast cancer. Oncological and cardiological evaluation of the patient was done and detected minimal palpable lesion in the surgery scar. Incisional biopsy of the lump in the surgery scar was positive for Infiltrative Ductal Breast Carcinoma. Tc-99m-MIBI is useful for detection of recurrence of breast carcinoma in surgery scar

    Full Text Available Data of evidence based cardiology including results of international clinical trials on efficacy and safety of the modern calcium channel blocker (CCB, lercanidipine, are presented. Results of these trials show the firm position of lercanidipine in the modern cardiology and confirm that treatment with lercanidipine leads to significant reduction of systolic and diastolic blood pressure (BP with no effect on heart rate (HR. Peripheral edema (the common side effect of CCBs occurs rarer with lercanidipine treatment than this with any other CCB treatment. Lercanidipine can be recommended to patients with concomitant diseases due to its additional features.

  13. Early Freezing of Gait: Atypical versus Typical Parkinson Disorders

    2015-01-01

    Full Text Available In 18 months, 850 patients were referred to Muhammad Ali Parkinson Center (MAPC. Among them, 810 patients had typical Parkinson disease (PD and 212 had PD for ≤5 years. Among the 212 patients with early PD, 27 (12.7% had freezing of gait (FOG. Forty of the 850 had atypical parkinsonism. Among these 40 patients, all of whom had symptoms for ≤5 years, 12 (30.0% had FOG. FOG improved with levodopa in 21/27 patients with typical PD but did not improve in the 12 patients with atypical parkinsonism. FOG was associated with falls in both groups of patients. We believe that FOG unresponsive to levodopa in typical PD resembles FOG in atypical parkinsonism. We thus compared the 6 typical PD patients with FOG unresponsive to levodopa plus the 12 patients with atypical parkinsonism with the 21 patients with typical PD responsive to levodopa. We compared them by tests of locomotion and postural stability. Among the patients with FOG unresponsive to levodopa, postural stability was more impaired than locomotion. This finding leads us to believe that, in these patients, postural stability, not locomotion, is the principal problem underlying FOG.

  14. Typical horticultural products between tradition and innovation

    Directory of Open Access Journals (Sweden)

    Innocenza Chessa

    Full Text Available Recent EU and National policies for agriculture and rural development are mainly focused to foster the production of high quality products as a result of the increasing demand of food safety, typical foods and traditional processing methods. Another word very often used to describe foods in these days is “typicality” which pools together the concepts of “food connected with a specific place”, “historical memory and tradition” and “culture”. The importance for the EU and the National administrations of the above mentioned kind of food is demonstrated, among other things, by the high number of the PDO, PGI and TSG certificated products in Italy. In this period of global markets and economical crisis farmers are realizing how “typical products” can be an opportunity to maintain their market share and to improve the economy of local areas. At the same time, new tools and strategy are needed to reach these goals. A lack of knowledge has being recognized also on how new technologies and results coming from recent research can help in exploiting traditional product and in maintaining the biodiversity. Taking into account the great variety and richness of typical products, landscapes and biodiversity, this report will describe and analyze the relationships among typicality, innovation and research in horticulture. At the beginning “typicality” and “innovation” will be defined also through some statistical features, which ranks Italy at the first place in terms of number of typical labelled products, then will be highlighted how typical products of high quality and connected with the tradition and culture of specific production areas are in a strict relationship with the value of agro-biodiversity. Several different examples will be used to explain different successful methods and/or strategies used to exploit and foster typical Italian vegetables, fruits and flowers. Finally, as a conclusion, since it is thought that

    Many hospitals experience a reduction in the number of available physicians on days when national scientific meetings are conducted. This study investigates the relationship between in-hospital mortality in acute myocardial infarction (AMI) patients and admission during national cardiology meeting dates. Using an administrative database, we analyzed patients with AMI admitted to acute care hospitals in Japan from 2011 to 2013. There were 3 major national cardiology meetings held each year. A hierarchical logistic regression model was used to compare in-hospital mortality and treatment patterns between patients admitted on meeting dates and those admitted on identical days during the week before and after the meeting dates. We identified 6,332 eligible patients, with 1,985 patients admitted during 26 meeting days and 4,347 patients admitted during 52 non-meeting days. No significant differences between meeting and non-meeting dates were observed for in-hospital mortality (7.4% vs. 8.5%, respectively; p=0.151, unadjusted odds ratio: 0.861, 95% confidence interval: 0.704-1.054) and the proportion of percutaneous coronary intervention (PCI) performed on the day of admission (75.9% vs. 76.2%, respectively; p=0.824). We also found that some low-staffed hospitals did not treat AMI patients during meeting dates. Little or no "national meeting effect" was observed on in-hospital mortality in AMI patients, and PCI rates were similar for both meeting and non-meeting dates. Our findings also indicated that during meeting dates, AMI patients may have been consolidated to high-performance and sufficiently staffed hospitals. Copyright © 2016 Elsevier Ireland Ltd.

    The aim of this study was to determine students' satisfaction with an e-learning environment which is developed to support classical problem-based learning (PBL) in medical education and its effect on academic achievement. In this cross-sectional study, students were provided with a web-based learning environment including learning materials related to objectives of the subject of PBL module, which could be used during independent study period. The study group comprised of all of the second year students (164 students) of Akdeniz University, Medical Faculty, during 2007-2008 education period. In order to gather data about students' satisfaction with learning environment, a questionnaire was administered to the students. Comparison of students' academic achievement was based on their performance score in PBL exam. Statistical analyses were performed using unpaired t test and Mann Whitney U test. Findings indicated that 72.6% of the students used e-learning practice. There is no statistically significant difference between mean PBL performance scores of users and non-users of e-learning practice (103.58 vs. 100.88) (t=-0.998, p=0.320). It is found that frequent users of e-learning application had statistically significant higher scores than non-frequent users (106.28 vs. 100.59) (t=-2.373, p=0.01). In addition, 72.6% of the students declared they were satisfied with the application. Our study demonstrated that the most of the students use e-learning application and are satisfied with it. In addition, it is observed that e-learning application positively affects the academic achievement of the students. This study gains special importance by providing contribution to limited literature in the area of instructional technology in PBL and Cardiology teaching.

    in-hospital life-threatening ventricular arrhythmias (LT-VA) may complicate the course of cardiovascular patients. We aimed to assess the incidence, circumstances, determinants, and outcome of in-hospital LT-VA in order to help clinicians in prescribing appropriate levels of monitoring. the study population consisted of all 10,741 consecutive patients (65 ± 15 years, 67.7% males) admitted to a cardiology department in 2009-2014. Terminally ill patients and those with primary arrhythmia diagnosis were excluded. The composite end-point included sudden arrhythmic death, ventricular fibrillation, unstable ventricular tachycardia and appropriate ICD shock unrelated to invasive interventions. the incidence of LT-VA was 0.6%, with no differences regarding age, gender and primary diagnosis of coronary artery disease between patients with and without LT-VA. The incidence of LT-VA was significantly higher (1.2% versus 0.1%, p<0.001) among urgent compared with elective admissions and among patients with left ventricular ejection fraction (LV-EF) <45% (1.7% versus 0.2%, p<0.001). At multivariable analysis, urgent admission and LV-EF <45%, but not primary diagnosis of coronary artery disease, remained independent predictors of LT-VA. At the time of the event, 97.1% fulfilled either class I or class II indications for telemetry monitoring according to the American Heart Association guidelines. Survival to discharge with good neurological status was 70.6%. acutely ill patients with heart failure and LV systolic dysfunction showed the highest rate of LT-VAs, regardless of the underlying cardiac disease (ischemic or non-ischemic). Current guidelines demonstrated high sensitivity in identifying patients at risk. These findings may favor proper utilization of telemetry monitoring resources. Copyright © 2016.

    Dilated cardiomyopathy (DCM) is the most common cardiac disease in large breed dogs and is inherited in Doberman Pinschers with a high prevalence (58%). The European Society for Veterinary Cardiology convened a task force to formulate screening guidelines for DCM in Dobermans. Screening for occult DCM in Dobermans should start at three years of age and use both Holter monitoring and echocardiography. Yearly screening over the life of the dog is recommended, as a one-time screening is not sufficient to rule out future development of DCM. The preferred echocardiographic method is the measurement of the left ventricular volume by Simpson's method of discs (SMOD). Less than 50 single ventricular premature complexes (VPCs) in 24 h are considered to be normal in Dobermans, although detection of any number of VPCs is cause for concern. Greater than 300 VPCs in 24 h or two subsequent recordings within a year showing between 50 and 300 VPCs in 24 h is considered diagnostic of occult DCM in Dobermans regardless of the concurrent echocardiographic findings. The guidelines also provide recommendations concerning ancillary tests, that are not included in the standard screening protocol, but which may have some utility when recommended tests are not available or financially untenable on an annual basis. These tests include assay of cardiac biomarkers (Troponin I and N-Terminal pro-B-type Natriuretic Peptide) as well as a 5-min resting electrocardiogram (ECG). The current guidelines should help to establish an early diagnosis of DCM in Dobermans. Crown Copyright © 2017. Published by Elsevier B.V. All rights reserved.

  19. Evaluation of patients skin dose undergoing interventional cardiology procedure using radiochromic films

    In interventional cardiology (IC), coronary angiography (CA) and percutaneous transluminal coronary angioplasty (PTCA) procedures are the most frequent ones. Since the 1990s, the number of IC procedures has increased rapidly. It is also known that these procedures are associated with high radiation doses due to long fluoroscopy time (FT) and large number of cine-frames (CF) acquired to document the procedure. Mapping skin doses in IC is useful to find the probability of skin injuries, to detect areas of overlapping field, and to get a permanent record of the most exposed areas of skin. The purpose of this study was to estimate the maximum skin dose (MSD) in patients undergoing CA and PTCA, and to compare these values with the reference levels proposed in the literature. Patients' dose measurements were carried out on a sample of 38 patients at the hemodynamic department, in four local hospitals in Rio de Janeiro, Brazil, using Gafchromic XR-RV2 films. In PTCA procedures, the median and third quartile values of MSD were estimated at 2.5 and 5.3 Gy, respectively. For the CA procedures, the median and third quartile values of MSD were estimated at 0.5 and 0.7 Gy, respectively. In this paper, we used the Pearson's correlation coefficient (r), and we found a fairly strong correlation between FT and MSD (r=0.8334, p<0.0001), for CA procedures. The 1 Gy threshold for deterministic effects was exceeded in nine patients. The use of Gafchromic XR-RV2 films was shown to be an effective method to measure MSD and the dose distribution map. The method is effective to identify the distribution of radiation fields, thus allowing the follow-up of the patient to investigate the appearance of skin injuries. (author)

  20. Radiation-Induced Noncancer Risks in Interventional Cardiology: Optimisation of Procedures and Staff and Patient Dose Reduction

    Khairuddin Md Yusof, Ahmad

    2013-01-01

    Concerns about ionizing radiation during interventional cardiology have been increased in recent years as a result of rapid growth in interventional procedure volumes and the high radiation doses associated with some procedures. Noncancer radiation risks to cardiologists and medical staff in terms of radiation-induced cataracts and skin injuries for patients appear clear potential consequences of interventional cardiology procedures, while radiation-induced potential risk of developing cardiovascular effects remains less clear. This paper provides an overview of the evidence-based reviews of concerns about noncancer risks of radiation exposure in interventional cardiology. Strategies commonly undertaken to reduce radiation doses to both medical staff and patients during interventional cardiology procedures are discussed; optimisation of interventional cardiology procedures is highlighted.

    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

    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

    This article presents the most relevant developments in 2013 in 3 key areas of cardiology: congenital heart disease, clinical cardiology, and heart failure and transplant. Within the area of congenital heart disease, we reviewed contributions related to sudden death in adult congenital heart disease, the importance of specific echocardiographic parameters in assessing the systemic right ventricle, problems in patients with repaired tetralogy of Fallot and indication for pulmonary valve replacement, and confirmation of the role of specific factors in the selection of candidates for Fontan surgery. The most recent publications in clinical cardiology include a study by a European working group on correct diagnostic work-up in cardiomyopathies, studies on the cost-effectiveness of percutaneous aortic valve implantation, a consensus document on the management of type B aortic dissection, and guidelines on aortic valve and ascending aortic disease. The most noteworthy developments in heart failure and transplantation include new American guidelines on heart failure, therapeutic advances in acute heart failure (serelaxin), the management of comorbidities such as iron deficiency, risk assessment using new biomarkers, and advances in ventricular assist devices.

    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.

    Safety culture is one of the requirements for preventing the occurrence of adverse effects. However, this has not been studied in the field of cardiology. The aim of this study is to evaluate the safety culture in a cardiology unit that has implemented and certified an integrated quality and risk management system for patient safety. A cross-sectional observational study was conducted in 2 consecutive years, with all staff completing the Spanish version of the questionnaire, "Hospital Survey on Patient Safety Culture" of the "Agency for Healthcare Research and Quality", with 42 items grouped into 12 dimensions. The percentage of positive responses in each dimension in 2014 and 2015 were compared, as well as national data and United States data, following the established rules. The overall assessment out of a possible 5, was 4.5 in 2014 and 4.7 in 2015. Seven dimensions were identified as strengths. The worst rated were: staffing, management support and teamwork between units. The comparison showed superiority in all dimensions compared to national data, and in 8 of them compared to American data. The safety culture in a Cardiology Unit with an integrated quality and risk management patient safety system is high, and higher than nationally in all its dimensions and in most of them compared to the United States.

    The first World Congress of Paediatric Cardiology was held in London, United Kingdom, in 1980, organised by Dr. Jane Somerville and Prof. Fergus Macartney. The idea was that of Jane Somerville, who worked with enormous energy and enthusiasm to bring together paediatric cardiologists and surgeons from around the world. The 2nd World Congress of Paediatric Cardiology took place in New York in 1985, organised by Bill Rashkind, Mary Ellen Engle, and Eugene Doyle. The 3rd World Congress of Paediatric Cardiology was held in Bangkok, Thailand, in 1989, organised by Chompol Vongraprateep. Although cardiac surgeons were heavily involved in these early meetings, a separate World Congress of Paediatric Cardiac Surgery was held in Bergamo, Italy, in 1988, organised by Lucio Parenzan. Thereafter, it was recognised that surgeons and cardiologists working on the same problems and driven by a desire to help children should really rather meet together. A momentous decision was taken to initiate a Joint World Congress of Paediatric Cardiology and Cardiac Surgery. A steering committee was established with membership comprising the main organisers of the four separate previous Congresses, and additional members were recruited in an effort to achieve numerical equality of cardiologists and surgeons and a broad geographical representation. The historic 1st "World Congress of Paediatric Cardiology and Cardiac Surgery" took place in Paris in June, 1993, organised by Jean Kachaner. The next was to be held in Japan, but the catastrophic Kobe earthquake in 1995 forced relocation to Hawaii in 1997.

    Varicella- zoster virus infection is an intriguing medical entity that involves many medical specialties including infectious diseases, immunology, dermatology, and neurology. It can affect patients from early childhood to old age. Its treatment requires expertise in pain management and psychological support. While varicella is caused by acute viremia, herpes zoster occurs after the dormant viral infection, involving the cranial nerve or sensory root ganglia, is re-activated and spreads orthodromically from the ganglion, via the sensory nerve root, to the innervated target tissue (skin, cornea, auditory canal, etc.). Typically, a single dermatome is involved, although two or three adjacent dermatomes may be affected. The lesions usually do not cross the midline. Herpes zoster can also present with unique or atypical clinical manifestations, such as glioma, zoster sine herpete and bilateral herpes zoster, which can be a challenging diagnosis even for experienced physicians. We discuss the epidemiology, pathophysiology, diagnosis and management of Herpes Zoster, typical and atypical presentations.

    The American College of Cardiology (ACC) Appropriate Use Criteria (AUC) for radionuclide myocardial perfusion scans (MPS) was developed to promote its rational use in the assessment of stable ischaemic heart disease (IHD). We sought to validate the applicability of this document in the Australian context. 1009 consecutive patients who underwent MPS were retrospectively audited at a single major metropolitan hospital in Victoria, Australia. Appropriateness was assigned based on the 2013 ACC AUC, and common indications and predictors of positive scan results were examined. The AUC was successfully applied (99.1%) retrospectively. A large proportion of scans were deemed appropriate (82.7%), whilst 7.8% were maybe appropriate. Positive detection rates in these groups were 17.0% and 17.9% respectively. Eighteen patients (1.8%) were unclassifiable, but had a detection rate of 44.4%. Positive predictors of an abnormal MPS result included prior history of coronary artery disease, typical angina, and following the conservative management of an acute coronary syndrome. Scans that were rarely appropriate had a detection rate of 0%. The retrospective application of the 2013 ACC AUC is feasible. Whilst the majority of the scans were appropriate, a group of unclassifiable patients was observed to have a high detection rate. Scans that were rarely appropriate could potentially be rationalised to reduce radiation risk.

    The Spanish Society of Cardiology holds an annual national meeting with a large number of presentations but the number of full-text publications resulting from these presentations and the journals accepting these manuscripts is unknown. This study aimed to identify the full-text publication rate of accepted abstracts and to analyze the bibliometric features of subsequent publications. We randomly selected a sample of 300 oral presentations at the meetings of the Spanish Society of Cardiology in 2002, 2005 and 2008. Subsequent publications were identified through the Science Citation Index-Expanded, Scopus, Índice Médico Español, and Índice Bibliográfico Español en Ciencias de la Salud. Of 300 abstracts, 115 resulted in 147 full publications, representing a publication rate of 38.33%. The meeting with the highest publication rate (43%) was held in 2005. The subject category with the highest number of publications was Pediatric Cardiology/Congenital Heart Disease (58.8%). Time to full publication was usually 2 years (30.61%). Articles were published in 57 journals. The journals publishing the highest number of articles were Revista Española de Cardiología (n=55; 37.41%) and the European Heart Journal (n=8; 5.44%). The high percentage of articles published in the upper half of journals listed in Journal Citation Reports under the category of cardiac and cardiovascular system (83%) can be taken as an objective quality indicator of the results presented at these meetings. However, more than 60% of the abstracts did not result in full publications, thus depriving the scientific community of potentially interesting results.

    To understand statewide variation in preoperative cardiology consultation prior to major vascular surgery and to determine whether consultation was associated with differences in perioperative myocardial infarction (poMI). Medical consultation prior to major vascular surgery is obtained to reduce perioperative risk. Despite perceived benefit of preoperative consultation, evidence is lacking specifically for major vascular surgery on the effect of preoperative cardiac consultation. Patient and clinical data were obtained from a statewide vascular surgery registry between January 2012 and December 2014. Patients were risk stratified by revised cardiac risk index category and compared poMI between patients who did or did not receive a preoperative cardiology consultation. We then used logistic regression analysis to compare the rate of poMI across hospitals grouped into quartiles by rate of preoperative cardiology consultation. Our study population comprised 5191 patients undergoing open peripheral arterial bypass (n = 3037), open abdominal aortic aneurysm repair (n = 332), or endovascular aneurysm repair (n = 1822) at 29 hospitals. At the patient level, after risk-stratification by revised cardiac risk index category, there was no association between cardiac consultation and poMI. At the hospital level, preoperative cardiac consultation varied substantially between hospitals (6.9%-87.5%, P 66%) had a reduction in poMI (OR, 0.52; confidence interval: 0.28-0.98; P cardiology consultation for vascular surgery varies greatly between institutions, and does not appear to impact poMI at the patient level. However, reduction of poMI was noted at the hospitals with the highest rate of preoperative cardiology consultation as well as a variety of medical services, suggesting that other hospital culture effects play a role.

    The number of cardiology interventional procedures has significantly increased recently. This is due to the reliability of the diagnostic equipment to diagnose many heart diseases. In the procedures the x-ray used results in increasing radiation doses to the staff. The cardiologists and other staff member in interventional cardiology are usually working close to the area under examination and receive the dose primarily as well as from scattered radiation from the patients. In this study three electronic personal dosimeters (EPDs) were used to measured personal equivalent dose Hp (10) for assessment staff doses were monitoring during interventional cardiology procedure, totally in (100) procedures were performed in two clinical. The procedures was collect in two main hospitals in Khartoum State, the staff workers include cardiologists, technologists and nurses. The EPDs were used by each worker at the two cardiology centers, was one worn under a protective apron attach to chest. The annual doses received by 6 cardiologists, 6 nurses and 2 technologists at the sudan heart center were tn the range: (27.25-33.5) μSv, (3.25-3.66) μSv, (3.25-3.66) μSv, (3.23 and 3.70) μSv respectively. In the royal care hospital the annual doses received by 2 doctors, 4 nurses and 2 technologists were in the range ( 38.375 and 39.375) μSv (12.06-14.125) μSv, (8.5 and 9.25) μSv respectively, estimated for four weeks. The highest doses were received by the cardiologist followed by nurses and the x-ray technicians. The results showed that the annual doses received by the workers do not exceed 20 mSv. Recommendation on how to reduce staff doses in interventional cardiology are presented.(Author)

  5. Spectra of conditionalization and typicality in the multiverse

    An approach to testing theories describing a multiverse, that has gained interest of late, involves comparing theory-generated probability distributions over observables with their experimentally measured values. It is likely that such distributions, were we indeed able to calculate them unambiguously, will assign low probabilities to any such experimental measurements. An alternative to thereby rejecting these theories, is to conditionalize the distributions involved by restricting attention to domains of the multiverse in which we might arise. In order to elicit a crisp prediction, however, one needs to make a further assumption about how typical we are of the chosen domains. In this paper, we investigate interactions between the spectra of available assumptions regarding both conditionalization and typicality, and draw out the effects of these interactions in a concrete setting; namely, on predictions of the total number of species that contribute significantly to dark matter. In particular, for each conditionalization scheme studied, we analyze how correlations between densities of different dark matter species affect the prediction, and explicate the effects of assumptions regarding typicality. We find that the effects of correlations can depend on the conditionalization scheme, and that in each case atypicality can significantly change the prediction. In doing so, we demonstrate the existence of overlaps in the predictions of different "frameworks" consisting of conjunctions of theory, conditionalization scheme and typicality assumption. This conclusion highlights the acute challenges involved in using such tests to identify a preferred framework that aims to describe our observational situation in a multiverse.

    Recent findings show that typical faces are judged as more trustworthy than atypical faces. However, it is not clear whether employment of typicality cues in trustworthiness judgment happens across cultures and if these cues are culture specific. In two studies, conducted in Japan and Israel, participants judged trustworthiness and attractiveness of faces. In Study 1, faces varied along a cross-cultural dimension ranging from a Japanese to an Israeli typical face. Own-culture typical faces were perceived as more trustworthy than other-culture typical faces, suggesting that people in both cultures employ typicality cues when judging trustworthiness, but that the cues, indicative of typicality, are culture dependent. Because perceivers may be less familiar with other-culture typicality cues, Study 2 tested the extent to which they rely on available facial information other than typicality, when judging other-culture faces. In Study 2, Japanese and Israeli faces varied from either Japanese or Israeli attractive to unattractive with the respective typical face at the midpoint. For own-culture faces, trustworthiness judgments peaked around own-culture typical face. However, when judging other-culture faces, both cultures also employed attractiveness cues, but this effect was more apparent for Japanese participants. Our findings highlight the importance of culture when considering the effect of typicality on trustworthiness judgments.

    Over the course of childhood, children's thinking about social groups changes in a variety of ways. Developmental Subjective Group Dynamics (DSGD) theory emphasizes children's understanding of the importance of conforming to group norms. Abrams et al.'s study, which uses DSGD theory as a framework, demonstrates the social cognitive skills underlying young elementary school children's thinking about group norms. Future research on children's thinking about groups and group norms should explore additional elements of this topic, including aspects of typicality beyond loyalty. © 2014 The British Psychological Society.

The calculations started on static analysis of typical structures made of non linear materials stressed by cyclic loads. The fluid structure interaction analysis is also being considered. Reasons and details of the different benchmark calculations are described, results obtained are commented and future computational exercise indicated

  12. The Typicality Ranking Task: A New Method to Derive Typicality Judgments from Children

    Science.gov (United States)

    Ameel, Eef; Storms, Gert

    2016-01-01

    An alternative method for deriving typicality judgments, applicable in young children that are not familiar with numerical values yet, is introduced, allowing researchers to study gradedness at younger ages in concept development. Contrary to the long tradition of using rating-based procedures to derive typicality judgments, we propose a method that is based on typicality ranking rather than rating, in which items are gradually sorted according to their typicality, and that requires a minimum of linguistic knowledge. The validity of the method is investigated and the method is compared to the traditional typicality rating measurement in a large empirical study with eight different semantic concepts. The results show that the typicality ranking task can be used to assess children’s category knowledge and to evaluate how this knowledge evolves over time. Contrary to earlier held assumptions in studies on typicality in young children, our results also show that preference is not so much a confounding variable to be avoided, but that both variables are often significantly correlated in older children and even in adults.

    2007-01-01

    Typical meteorological years (TMYs) for 60 cities in the five major climatic zones (severe cold, cold, hot summer and cold winter, hot summer and warm winter, mild) in China were investigated. Long term (1971-2000) measured weather data such as dry bulb and dew point temperatures, wind speed and global solar radiation were gathered and analysed. A total of seven climatic indices were used to select the 12 typical meteorological months (TMMs) that made up the TMY for each city. In general, the cumulative distribution functions of the TMMs selected tended to follow their long term counterparts quite well. There was no persistent trend in any particular years being more representative than the others, though 1978 and 1982 tended to be picked most often. This paper presents the work and its findings. Future work on the assessment of TMYs in building energy simulation is also discussed

    Most contemporary 12-lead electrocardiogram (ECG) devices offer computerized diagnostic proposals. The reliability of these automated diagnoses is limited. It has been suggested that incorrect computer advice can influence physician decision-making. This study analyzed the role of diagnostic proposals in the decision process by a group of fellows of cardiology and other internal medicine subspecialties. A set of 100 clinical 12-lead ECG tracings was selected covering both normal cases and common abnormalities. A team of 15 junior Cardiology Fellows and 15 Non-Cardiology Fellows interpreted the ECGs in 3 phases: without any diagnostic proposal, with a single diagnostic proposal (half of them intentionally incorrect), and with four diagnostic proposals (only one of them being correct) for each ECG. Self-rated confidence of each interpretation was collected. Availability of diagnostic proposals significantly increased the diagnostic accuracy (p<0.001). Nevertheless, in case of a single proposal (either correct or incorrect) the increase of accuracy was present in interpretations with correct diagnostic proposals, while the accuracy was substantially reduced with incorrect proposals. Confidence levels poorly correlated with interpretation scores (rho≈2, p<0.001). Logistic regression showed that an interpreter is most likely to be correct when the ECG offers a correct diagnostic proposal (OR=10.87) or multiple proposals (OR=4.43). Diagnostic proposals affect the diagnostic accuracy of ECG interpretations. The accuracy is significantly influenced especially when a single diagnostic proposal (either correct or incorrect) is provided. The study suggests that the presentation of multiple computerized diagnoses is likely to improve the diagnostic accuracy of interpreters. Copyright © 2017 Elsevier B.V. All rights reserved.

We performed a retrospective study of eight patients diagnosed of renal oncocytoma, analyzing the characteristics found in the plain radiography and IVU, ultrasonography and CT without and with i. v. contrast. The masses were well defined in seven cases and poorly defined in one, and were homogeneous on four occasions and heterogeneous on two. The remaining two were homogeneous, except for the presence of a central scar. Two lesions showed and aggressive biological behavior, coinciding with signs suggestive of malignancy from the radiological point of view. The fibrous scar is a typical but infrequent findings in renal oncocytoma that we can only detect by CT. It is not possible to differentiate it from aggressive lesions with imaging techniques, although orientative findings exist. (Author) 17 refs

    Radionuclide investigations today are an important tool in cardiology. They close the diagnostic gap in cases where non-invasive procedures of cardiological diagnosis such as ecg, exercise-ecg, echocardiography and chest-x-ray remains unrevealing. Further, they are helpful when an exact quantitation of the disease or a precise follow-up is required. Radionuclide techniques are very useful to detect myocardial ischemia in patients with coronary heart disease and to judge myocardial function in patients with aortic or mitral regurgitation. Follow-up investigations after therapy (aortocoronary bypass, PTCA, valve replacement) permit conclusions regarding the benefit of these measures. Results of radionuclide investigations should consider the Bayes' theorem in order to keep false-negative and false-positive reports as low as possible. (orig.) [de

    2016-02-01

    Cardiovascular magnetic resonance plays an increasingly important role in routine cardiology clinical practice. It is a versatile imaging modality that allows highly accurate, broad and in-depth assessment of cardiac function and structure and provides information on pertinent clinical questions in diseases such as ischemic heart disease, nonischemic cardiomyopathies, and heart failure, as well as allowing unique indications, such as the assessment and quantification of myocardial iron overload or infiltration. Increasing evidence for the role of cardiovascular magnetic resonance, together with the spread of knowledge and skill outside expert centers, has afforded greater access for patients and wider clinical experience. This review provides a snapshot of cardiovascular magnetic resonance in modern clinical practice by linking image acquisition and postprocessing with effective delivery of the clinical meaning.

    The last few decades have seen substantial growth in the populations of competitive athletes and highly active people (CAHAP). Although vigorous physical exercise is an effective way to reduce the risk of cardiovascular (CV) disease, CAHAP remain susceptible to inherited and acquired CV disease, and may be most at risk for adverse CV outcomes during intense physical activity. Traditionally, multidisciplinary teams comprising athletic trainers, physical therapists, primary care sports medicine physicians, and orthopedic surgeons have provided clinical care for CAHAP. However, there is increasing recognition that a care team including qualified CV specialists optimizes care delivery for CAHAP. In recognition of the increasing demand for CV specialists competent in the care of CAHAP, the American College of Cardiology has recently established a Sports and Exercise Council. An important primary objective of this council is to define the essential skills necessary to practice effective sports cardiology. Copyright © 2017. Published by Elsevier Inc.

    Scales of quality of life have only recently been imposed in cardiology. Essentially an Anglosaxon invention, they have been used for evaluating most treatment of cardiac failure. The main qualities of a good quality of life questionnaire are its sensitivity, its reproducibility and its validity. The contents of the questionnaire, particularly the relationship between items concerning symptoms and those concerning the psychological aspects of the disease, have a great influence on the quality of results. The "Living with Heart Failure Questionnaire" of the University of Minnesota is the most validated questionnaire at present. As with most other methods of therapeutic assessment in cardiology, the most recently obtained results from large multicenter trials, seem to show a much smaller benefit of drugs reputed to be effective in this condition, with respect to the quality of life of patients. This justifies: the continuation of validation of these questionnaires, a reflection on the efficacy of classical management of these patients.

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.

    Full Text Available The local development is based on the integration of the tourism sector with the whole economy. The rural tourism seems to be a good occasion to analyse the local development: consumption of "tourist products" located in specific local contexts. Starting from the food and wine supply chain and the localization of typical productions, the aim of the present work will be analyse the relationship with local development, rural tourism sustainability and accommodation system, referring to Lazio. Which are the findings to create tourism local system based on the relationship with touristic and food and wine supply chain? Italian tourism is based on accommodation system, so the whole consideration of the Italian cultural tourism: tourism made in Italy. The touristic added value to specific local context takes advantage from the synergy with food and wine supply chain: made in Italy of typical productions. Agritourism could be better accommodation typology to rural tourism and to exclusivity of consumption typical productions. The reciprocity among food and wine supply chain and tourism provides new insights on the key topics related to tourism development and to the organization of geographical space as well and considering its important contribution nowadays to the economic competitiveness.

  7. Typically Female Features in Hungarian Shopping Tourism

    Full Text Available Although shopping has been long acknowledged as a major tourist activity, the extent and characteristics of shopping tourism have only recently become the subject of academic research and discussion. As a contribution to this field of knowledge, the paper presents the characteristics of shopping tourism in Hungary, and discusses the typically female features of outbound Hungarian shopping tourism. The research is based on a survey of 2473 Hungarian tourists carried out in 2005. As the findings of the study indicate, while female respondents were altogether more likely to be involved in tourist shopping than male travellers, no significant difference was experienced between the genders concerning the share of shopping expenses compared to their total travel budget. In their shopping behaviour, women were typically affected by price levels, and they proved to be both more selfish and more altruistic than men by purchasing more products for themselves and for their family members. The most significant differences between men and women were found in their product preferences as female tourists were more likely to purchase typically feminine goods such as clothes, shoes, bags and accessories, in the timing of shopping activities while abroad, and in the information sources used by tourists, since interpersonal influences such as friends’, guides’ and fellow travellers’ recommendations played a higher role in female travellers’ decisions.

    Workers involved in interventional cardiology procedures receive high eye lens doses if radiation protection tools are not properly utilized. Currently, there is no suitable method for routine measurement of eye dose. In Thailand, the eye lens equivalent doses in terms of Hp(3) of the interventional cardiologists, nurses, and radiographers participating in interventional cardiology procedures have been measured at 12 centers since 2015 in the pilot study. The optically stimulated luminescence (OSL) dosimeter was used for measurement of the occupational exposure and the eye lens dose of 42 interventional cardiology personnel at King Chulalongkorn Memorial Hospital as one of the pilot centers. For all personnel, it is recommended that a first In Light OSL badge is placed at waist level and under the lead apron for determination of Hp(10); a second badge is placed at the collar for determination of Hp(0.07) and estimation of Hp(3). Nano Dots OSL dosimeter has been used as an eye lens dosimeter for 16 interventional cardiology personnel, both with and without lead-glass eyewear. The mean effective dose at the body, equivalent dose at the collar, and estimated eye lens dose were 0.801, 5.88, and 5.70 mSv per year, respectively. The mean eye lens dose measured by the Nano Dots dosimeter was 8.059 mSv per year on the left eye and 3.552 mSv per year on the right eye. Two of 16 interventional cardiologists received annual eye lens doses on the left side without lead glass that were higher than 20 mSv per year, the new eye lens dose limit as recommended by ICRP with the risk of eye lens opacity and cataract.

    2014-01-01

    Background The National Health Service is reconfiguring health care services in order to meet the increasing challenge of providing care for people with long-term conditions and to reduce the demand on specialised outpatient hospital services by enhancing primary care. A review of cardiology referrals to specialised care and the literature on referral management inspired the development of a new GP role in Cardiology. This new extended role was developed to enable GPs to diagnose and manage patients with mild to moderate heart failure or atrial fibrillation and to use a range of diagnostics effectively in primary care. This entailed GPs participating in a four-session short course with on-going clinical supervision. The new role was piloted in a small number of GP practices in one county in England for four months. This study explores the impact of piloting the Extended Cardiology role on the GP’s role, patients’ experience, service delivery and quality. Methods A mixed methods approach was employed including semi-structured interviews with GPs, a patient experience survey, a quality review of case notes, and analysis on activity and referral data. Results The participating GPs perceived the extended GP role as a professional development opportunity that had the potential to reduce healthcare utilisation and costs, through a reduction in referrals, whilst meeting the patient’s wishes for the provision of care closer to home. Patient experience of the new GP service was positive. The standard of clinical practice was judged acceptable. There was a fall in referrals during the study period. Conclusion This new role in cardiology was broadly welcomed as a model of care by the participating GPs and by patients, because of the potential to improve the quality of care for patients in primary care and reduce costs. As this was a pilot study further development and continuing evaluation of the model is recommended. PMID:24885826

    In 2003, work-hour regulations were implemented by the Accreditation Council for Graduate Medical Education. Much has been published regarding resident rest and quality of life as well as patient safety. There has been no examination on the effect of work-hour restrictions on academic productivity of fellows in training. Paediatric subspecialty fellows have a scholarly requirement mandated by the American Board of Pediatrics. We have examined the impact of work-hour restrictions on the scholarly productivity of paediatric cardiology fellows during their fellowship. We conducted a literature search for all paediatric cardiology fellows between 1998 and 2007 at a single academic institution as first or senior authors on papers published during their 3-year fellowship and 3 years after completion of their categorical fellowship (n=63, 30 fellows before 2003 and 33 fellows after 2003). The numbers of first- or senior-author fellow publications before and after 2003 were compared. We also collected data on final paediatric cardiology subspecialty career choice. There was no difference in the number of fellow first-author publications before and after 2003. Before work-hour restrictions, the mean number of publications per fellow was 2.1 (±2.2), and after work-hour restrictions it was 2.0 (±1.8), (p=0.89). By subspecialty career choice, fellows who select electrophysiology, preventative cardiology, and heart failure always published within the 6-year time period. Since the implementation of work-hour regulations, total number of fellow first-authored publications has not changed. The role of subspecialty choice may play a role in academic productivity of fellows in training.

    There is currently great interest in measuring trainee competency at all levels of medical education. In 2007, we implemented a system for assessing cardiology fellows' progress in attaining imaging skills. This paradigm could be adapted for use by other cardiology programs. Evaluation consisted of a two-part exercise performed after years 1 and 2 of pediatric cardiology training. Part 1: a directly observed evaluation of technical skills as fellows imaged a normal subject (year 1) and a patient with complex heart disease (year 2). Part 2: fellows interpreted and wrote reports for two echocardiograms illustrating congenital heart disease. These were graded for accuracy and facility with communicating pertinent data. After 5 years of testing, fellows were surveyed about their experience. In 5 years, 40 fellows were tested at least once. Testing identified four fellows who underperformed on the technical portion and four on the interpretive portion. Surveys were completed by 33 fellows (83 %). Most (67 %) felt that intermittent observation by faculty was inadequate for assessing skills and that procedural volume was a poor surrogate for competency (58 %). Posttest feedback was constructive and valuable for 90, and 70 % felt the process helped them set goals for skill improvement. Overall, fellows felt this testing was fair and should continue. Fellow performance and responses identified programmatic issues that were creating barriers to learning. We describe a practical test to assess competency for cardiology fellows learning echocardiography. This paradigm is feasible, has excellent acceptance among trainees, and identifies trainees who need support. Materials developed could be easily adapted to help track upcoming ACGME-mandated metrics.

    Terminology and Lexicography have been especially addressed to the Allied Health Sciences regarding discussion of case reports or concerning publication of scientific articles. The knowledge of Human Anatomy enables the understanding of medical terms and the refinement of Medical Terminology makes possible a better anatomicomedical communication in a highly technical level. Most of the scientific publications in both Anatomy and Medicine are found only in English and most of dictionaries or search resources available do not have specificity enough to explain anatomicomedical, terminological, or lexicographical occurrences. To design and produce a multilingual terminological dictionary (Latin-English-Portuguese-Spanish) containing a list of English anatomicomedical terms in common usage in cardiology subspecialties addressed to medical students and professionals, to other allied health sciences professionals, and to translators working in this specific field. Terms, semantical and grammatical components were selected to compose an anatomicocardiological corpus. The adequacy to the thematic terminological research requests and the translation reliability level will be settled from the terminology specificity in contrast to the semantics, as well as from a peer survey of the main terms used by national and international experts in specialized journals, Internet sites, and from text-books on Anatomy and Cardiology. The inclusion criteria will be the terms included in the English, Portuguese, and Spanish Terminologia Anatomica - the official terminology of the anatomical sciences; nonofficial technical commonly used terms which lead to terminology or translation misunderstanding often being a source of confusion. A table with a sample of the 508 most used anatomical cardiologic terms in English language peer-reviewed journals of cardiology and (pediatric and adult) thoracic surgery is shown.

    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 123 I-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 123 I-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)

    Full Text Available The aim of this work is to attract attention of teachers, scientific personnel, engineers and students to one peculiarity of extremum seeking in different electrical problems. This feature lies in the fact that in many parts of electrical engineering extremum seeking comes to analysis one and the same mathematical structure (T-structure, but differences lie only in many symbols (designation.In one problems this structure appear in finale, the most simple form, but in others – T-structure is “veiled”, and as a rule  we need  elementary algebraic transformation to detect it.Taking into account high frequency of this structure appearing in electrical problems, in the first part of article the authors  carried out the investigation of extremum characteristics of T-structure and show the results in easy algorithms. To determine the typical T-structure there were taken five problems-examples for extremum seeking  from different parts of electrical engineering. The first and the second examples belong to the theory of electrical circuits.In the first example the problem of maximum active load power obtaining was considered, in the second we see the solution of problem for inductive coupled circuit adjustment in order to obtain the hump current. In the third example the band active filter, built on operating amplifier, is analyzed. According to these methods, taken in the first part of article, the frequency is determined, on which amplifier provides maximum  amplification factor. The forth example deals with analysis of efficiency of transformer. According to algorithm, the optimal efficiency of transformer’s load and also equation for its maximum was determined in this article. In the fifth example the mechanical characteristics of induction motor is analyzed. It is indicated how, on the basis of algorithms article, to obtain equations for critical slip and motor moment, and also the simple development of formula Klossa.The methods of

    The appropriate evaluation of the ischemic heart disease due to it seriousness and high prevalence, limited by the expenses that arise from the illness, constitutes a challenge in our times for the daily practice. At the present time, nuclear cardiology competes with several non invasive techniques in the evaluation of the perfusion and the myocardial viability, being this requested in function of the real necessity of each patient. The applications that nuclear cardiology offers for the study of the myocardial perfusion are multiple. Clinical situations are reviewed in this article, such as the coronary illness, states previous to the non cardiac surgery, states after cardiac catheterization, coronary angioplasty, revascularization surgery, and evaluation of patient under long term medical treatment. The study of the myocardial perfusion allows that the coronary illness can be classified according to a low, intermediate or high probability, providing a wide prognosis information in relation to the extension and severity of the ischemia. In this study there are also remarked practical limits as for the selection of patients in order to achieve that the studies of nuclear cardiology offer an appropriate evaluation of the well-known or suspected coronary illness.

    American cultural diplomacy played a key role in the institutionalization of Brazilian cardiology. In 1942, Frank Wilson, an internationally recognized pioneer in electrocardiography, made an extended wartime visit to Rio de Janeiro and São Paulo. The visit was sponsored by the United States Department of State as part of Roosevelt's Good Neighbor Policy and brought Wilson together with a group of physicians who would establish the specialty of cardiology in Brazil. This US cultural and diplomatic initiative strengthened an academic network that was already evolving and would eventually prove to be of benefit to both sides. Latin American physicians began in the 1920s to visit Wilson's laboratory at the University of Michigan, where they established the relationships on which Wilson would build. While affiliation with the "Wilson school" advanced the cause of Brazilian cardiologists who sought to establish themselves as specialists, cooperation with Latin American physicians benefitted Wilson in his pursuit of wider recognition for his innovations in the use of electrocardiography (ECG). Wilson's identity as a scientific ambassador to Latin America helped in legitimating his approach to the clinical application of the ECG. A close examination of Wilson's relationship to Brazilian cardiology demonstrates the role played by science and medicine as a part of wartime cultural diplomacy, as well as the dynamics of the transnational circulation of scientific knowledge and practices. © The Author 2017.

    2000-12-01

    To provide easy retrieval, integration and evaluation of multimodal cardiology images and data in a web browser environment, distributed application technologies and java programming were used to implement a client-server architecture based on software agents. The server side manages secure connections and queries to heterogeneous remote databases and file systems containing patient personal and clinical data. The client side is a Java applet running in a web browser and providing a friendly medical user interface to perform queries on patient and medical test dat and integrate and visualize properly the various query results. A set of tools based on Java Advanced Imaging API enables to process and analyze the retrieved cardiology images, and quantify their features in different regions of interest. The platform-independence Java technology makes the developed prototype easy to be managed in a centralized form and provided in each site where an intranet or internet connection can be located. Giving the healthcare providers effective tools for querying, visualizing and evaluating comprehensively cardiology medical images and records in all locations where they can need them- i.e. emergency, operating theaters, ward, or even outpatient clinics- the developed prototype represents an important aid in providing more efficient diagnoses and medical treatments.

    Cardiac disease, both congenital and acquired, contributes significantly to morbidity and mortality in children. This article describes the status of pediatric cardiology at the Children's Heart Center in the American University of Beirut Medical Center. It addresses the available clinical services as well as the research and educational activities that are present at a tertiary center in Lebanon, a developing country with a population of 4 million. Lebanon has witnessed major developments in the field of pediatric cardiology over the past few years. About 650 babies are born with heart disease every year, with more than 425 needing treatment. Nearly all types of interventional catheterization procedures are currently being performed. About 300 open and closed pediatric cardiac surgeries are performed per year in Lebanon. In 2008, the in-hospital surgical mortality rate at our center was 2.6%, reflecting the good level of care in the treatment of children with congenital heart disease (CHD) in Lebanon. Basic research in the field of pediatric cardiology is emerging at our center. Our team has been studying the effect of chronic hypoxemia on the neonatal myocardium in an animal model of chronic hypoxia, as well as the study of molecular basis of CHD. Appropriate identification of cardiac disease, its epidemiology, and outcome is of utmost importance in guiding adequate care. Centralization of facilities is important to improve results and level of care.

    The US health care system faces an unsustainable trajectory of high costs and inconsistent outcomes. The fee-for-service payment model has contributed to inefficiency, and new payment methods are a promising approach to improving value. Health reforms are needed to increase patient access, reduce costs, and improve health care quality, and the landmark Medicare Access and CHIP Reauthorization Act presents a roadmap for reform. The product of a collaboration between primary care and cardiology clinicians, this review describes a conceptual approach to delivery and payment reforms that aim to better support primary care-cardiology comanagement of chronic cardiovascular disease (CVD). Few existing alternative payment models specifically address long-term management of CVD. Primary care medical homes and accountable care organizations come closest, but both emphasize primary care, and cardiologists have often not been well engaged. A collaborative care framework should articulate distinct roles and responsibilities for primary care and cardiology in CVD comanagement. Finally, a series of payment models aim to better support clinicians in providing accountable, seamless, and patient-centered cardiac care. Clinical leadership is essential during this time of change in the health care system. Patients often struggle to navigate a fragmented and expensive system, whereas clinicians often practice with incomplete information about tests, treatments, and recommendations by their colleagues. The payment models described in this review offer an opportunity to create more satisfying approaches to patient care while improving value. These models have potential to support more effective coordination and to facilitate broader health care system transformation.

    Full Text Available Successful veterinary treatment of animals requires owner adherence with a prescribed treatment plan. The aim of our study was to evaluate and compare the level of adherence of the owners of patients presented for behavioural, cardiological, urological, and oncological problems. At the end of the first examination, each owner completed a questionnaire. Then, the owners were called four times to fill out another questionnaire over the phone. With regard to the first questionnaire, statistically significant data concern behavioral medicine and cardiology. In the first area the owner’s worry decreases during the follow-up and the number of owners who would give away the animal increases. In cardiology, owners who think that the pathology harms their animal’s quality of life decreased significantly over time. With regard to the 9 additional follow-up questions, in behavioural medicine and urology the owner’s discomfort resulting from the animal’s pathology significantly decreases over time. Assessment of adherence appears to be an optimal instrument in identifying the positive factors and the difficulties encountered by owners during the application of a treatment protocol.

    2018-06-01

    Cardiovascular diseases represent a major cause of death and morbidity. Cardiac and vascular pathologies develop predominantly in the aged population in part due to lifelong exposure to numerous risk factors but are also found in children and during adolescence. In comparison to adults, much has to be learned about the molecular pathways driving cardiovascular diseases in the pediatric population. Sirtuins are highly conserved enzymes that play pivotal roles in ensuring cardiac homeostasis under physiological and stress conditions. In this review, we discuss novel findings about the biological functions of these molecules in the cardiovascular system and their possible involvement in pediatric cardiovascular diseases.

    Given high rates of heart failure (HF) hospitalizations and widespread adoption of the hospitalist model, patients with HF are often cared for on General Medicine (GM) services. Differences in discharge processes and 30-day readmission rates between patients on GM and those on Cardiology during the contemporary hospitalist era are unknown. The present study compared discharge processes and 30-day readmission rates of patients with HF admitted on GM services and those on Cardiology services. We retrospectively studied 926 patients discharged home after HF hospitalization. The primary outcome was 30-day all-cause readmission after discharge from index hospitalization. Although 60% of patients with HF were admitted to Cardiology services, 40% were admitted to GM services. Prevalence of cardiovascular and noncardiovascular co-morbidities were similar between patients admitted to GM services and Cardiology services. Discharge summaries for patients on GM services were less likely to have reassessments of ejection fraction, new study results, weights, discharge vital signs, discharge physical examinations, and scheduled follow-up cardiologist appointments. In a multivariable regression analysis, patients on GM services were more likely to experience 30-day readmissions compared with those on Cardiology services (odds ratio 1.43 95% confidence interval [1.05 to 1.96], p = 0.02). In conclusion, outcomes are better among those admitted to Cardiology services, signaling the need for studies and interventions focusing on noncardiology hospital providers that care for patients with HF.

    2013-09-01

    We explored the frequency with which typical adults make Theory of Mind (ToM) attributions, and under what circumstances these attributions occur. We used an experience sampling method to query 30 typical adults about their everyday thoughts. Participants carried a Personal Data Assistant (PDA) that prompted them to categorize their thoughts as Action, Mental State, or Miscellaneous at approximately 30 pseudo-random times during a continuous 10-h period. Additionally, participants noted the direction of their thought (self versus other) and degree of socializing (with people versus alone) at the time of inquiry. We were interested in the relative frequency of ToM (mental state attributions) and how prominent they were in immediate social exchanges. Analyses of multiple choice answers suggest that typical adults: (1) spend more time thinking about actions than mental states and miscellaneous things, (2) exhibit a higher degree of own- versus other-directed thought when alone, and (3) make mental state attributions more frequently when not interacting (offline) than while interacting with others (online). A significant 3-way interaction between thought type, direction of thought, and socializing emerged because action but not mental state thoughts about others occurred more frequently when participants were interacting with people versus when alone; whereas there was an increase in the frequency of both action and mental state attributions about the self when participants were alone as opposed to socializing. A secondary analysis of coded free text responses supports findings 1-3. The results of this study help to create a more naturalistic picture of ToM use in everyday life and the method shows promise for future study of typical and atypical thought processes.

    Although pediatrician-reported relevance of Canadian cardiology-specific objectives has been studied, similar data are not available for the 2016 American Board of Pediatrics (ABP) cardiology-specific objectives. This study asked Kentucky trainees, pediatricians, and pediatric cardiologists to identify "most important" content within these objectives. This cross-sectional study used an original, online survey instrument based on the 2016 ABP cardiology-specific objectives. We collected quantitative data (numerical indications of importance) and qualitative data (open-ended replies regarding missing content and difficulty in teaching and learning). Respondents indicated the top two choices of most important items within eight content areas. Descriptive statistics (frequencies and percentages) and chi-square analysis were calculated. Content within categories was organized using naturally occurring "clusters" and "gaps" in scores. Common themes among open-ended qualitative responses were identified using Pandit's version of Glaser and Strauss Grounded theory (constant comparison). Of the 136 respondents, 23 (17%) were residents, 15 (11%) fellows, 85 (62%) pediatricians, and 13 (10%) pediatric cardiologists. Of attendings, 80% reported faculty/gratis faculty status. Naturally occurring clusters in respondent-designated importance resulted in ≤3 "most selected" objectives per content area. Objectives in "most selected" content pertained to initial diagnosis (recognition of abnormality/disease) (n = 16), possible emergent/urgent intervention required (n = 14), building a differential (n = 8), and planning a workup (n = 4). Conversely, themes for "least selected" content included comanagement with subspecialist (n = 15), knowledge useful in patient-family communication (n = 9), knowledge that can be referenced (as needed) (n = 7), and longitudinal/follow-up concerns (n = 5). This study demonstrated the utility of an online survey

    To determine the usability, accuracy, and cost-effectiveness of two handheld single-lead electrocardiogram (ECG) devices for atrial fibrillation (AF) screening in a hospital population with an increased risk for AF. Hospitalized patients (n = 445) at cardiological or geriatric wards were screened for AF by two handheld ECG devices (MyDiagnostick and AliveCor). The performance of the automated algorithm of each device was evaluated against a full 12-lead or 6-lead ECG recording. All ECGs and monitor tracings were also independently reviewed in a blinded fashion by two electrophysiologists. Time investments by nurses and physicians were tracked and used to estimate cost-effectiveness of different screening strategies. Handheld recordings were not possible in 7 and 21.4% of cardiology and geriatric patients, respectively, because they were not able to hold the devices properly. Even after the exclusion of patients with an implanted device, sensitivity and specificity of the automated algorithms were suboptimal (Cardiology: 81.8 and 94.2%, respectively, for MyDiagnostick; 54.5 and 97.5%, respectively, for AliveCor; Geriatrics: 89.5 and 95.7%, respectively, for MyDiagnostick; 78.9 and 97.9%, respectively, for AliveCor). A scenario based on automated AliveCor evaluation in patients without AF history and without an implanted device proved to be the most cost-effective method, with a provider cost to identify one new AF patient of €193 and €82 at cardiology and geriatrics, respectively. The cost to detect one preventable stroke per year would be €7535 and €1916, respectively (based on average CHA 2 DS 2 -VASc of 3.9 ± 2.0 and 5.0 ± 1.5, respectively). Manual interpretation increases sensitivity, but decreases specificity, doubling the cost per detected patient, but remains cheaper than sole 12-lead ECG screening. Using AliveCor or MyDiagnostick handheld recorders requires a structured screening strategy to be effective and cost-effective in a hospital setting

    Cardiologist and other staff members receive high doses of scattered radiation. Cases of radiation-induced cataract among cardiology professionals have been reported in studies, estimates for the dose to eye lens ranged from 450 to 900 mSv per year (without ceiling suspended screen), over several years. Recent surveys regarding high prevalence of lens changes likely induced by radiation exposure suggest an urgent need for improved radiation safety and training, use of eye protection during catheterization procedures, and improved occupational dosimetry. In view of the evidence of radiation injuries, the ICRP recommends limiting the radiation dose to the lens to 20 mSv per year for occupational exposure. A system for optimizing the radiation exposure is the measurement of entrance surface air kerma (K{sub a,e}) and kerma-area product (P{sub KA}) for patient and scattered dose or dose rate at the position for the staff, under clinical working conditions using phantoms and defined technical factors. Correlating K{sub a,e} and P{sub KA} with the scatter dose, applying the attenuation factors protective devices can enable estimation of the lens doses for operators. The purpose of this work is: to study the possibility of establishing a procedure which is useful for scientific societies and the regulatory authority in the prevention and control of IOE dose and to control and improve the quality of procedures in interventional cardiology as an initiative to raise awareness and optimization of radiological protection. Measurements were taken in different cardiac laboratories. Clinical working conditions were reproduced during the experiments for the different hemodynamic angiographic projections and operating modes used in fluoroscopy and cine. A first K{sub a,e} rate reference proposal for the characterization of angiography for the different acquisition modes were 16; 35; 40 and 220 (mGy/min), respectively.

    . Managing concomitant construction of new galleries with continuing operation and/or closure in the existing galleries remains as another challenge. There is a need, during the project, to address targets very different in nature and which may potentially compete with each other. Alternative solutions are typically compared and evaluated with a view to lower potential impacts and risks to workers, people and the environment in the short and the long term to as low as reasonably practicable. This is often called 'radiological optimisation'. In repository development, the set of target functions can be much broader, blurring the meaning of 'optimisation'. The visibility and importance to optimisation for licensing varies from country to country, and it may take different names

    Full Text Available Typical absences (TA are brief primary generalized epileptic seizures characterized by sudden onset and termination. According to their definition, absences consist of impairment of consciousness that is synchronously accompanied by electroencephalographic (EEG changes as generalized spike–slow wave discharges of 3 or more Hz. The authors conducted an investigation of 1261 patients with different forms of epilepsy with onset of seizures from the first days of life to the age of 18 years. The patients were followed up from 1990 to 2010. Absence seizures were detected in 231 patients, which accounts for 18.3 % of all the epileptic patients. TA were found in 102 patients, which constitutes 8.1 % of all cases of epilepsy with onset of seizures beyond the age of 18 years. The paper provides a detailed analysis of a group of patients with TA in terms of anamnestic, clinical, electroencephalographic, and neuroimaging features and the results of therapy with antiepileptic drugs (AEDs. The age of onset of TA-associated epilepsy was from 9 months to 17 years (mean 9.4 ± 4.06 years. The disease occurred most frequently in young school-age children (41.2 %. Isolated TA as the only type of seizures were observed in the clinical picture of 28 (27.5 % patients. TA were concurrent with other types of seizures in other cases. The investigators have identified 4 types of seizures which TA (generalized convulsions, myoclonic seizures, febrile seizures, and eyelid myoclonia may be concurrent with. Neuroimaging stated there were no brain changes in 85.3 % of TA-associated epilepsy cases. Moderate diffuse subatrophic changes were detected in other cases (14.7 %. Local cerebral structural abnormalities were absent. The use of antiepileptic therapy as both monotherapy and polytherapy using different combinations showed the high efficacy of AEDs. Complete remission was achieved in 84.3 % of TA-associated epilepsy cases. An AED-induced reduction in the frequency of

    found in long-term studies (n=859, 2RCTs RR not 20% improved 0.51 CI 0.38 to 0.67 NNT 4;n=675 1RCT, RR not improved 40% 0.75 CI 0.66 to 0.84 NNT 5; n=675, 1 RCT, RR not 60% improved 0.90 CI 0.84 to 0.96, NNT 11). Risperidone was also more likely to reduce relapse at one year follow up, compared with haloperidol (n=367, 1 RCT, RR 0.64 CI 0.41 to 0.99, NNT 7). Less people allocated risperidone left studies before completion, both for short-term (n=3066, 16 RCTs, RR 0.76 CI 0.63 to 0.92, NNT 6) and long-term trials (n=1270, 4RCTs, RR 0.55 CI 0.42 to 0.73 NNT 4). For general movement disorders results favoured risperidone. People given risperidone had significantly fewer general movement disorders (including extrapyramidal side effects) than those receiving older typical antipsychotics (n=2702, 10 RCTs, RR 0.63 CI 0.56 to 0.71, NNT 3). Significantly fewer people given risperidone used antiparkinsonian drugs (n=2524, 11 RCTs, RR 0.66 CI 0.58 to 0.74, NNT 4). As regards body weight, however, four studies (n=1708) found people were more likely to gain weight if allocated risperidone compared to typical antipsychotics (RR 1.55 CI 1.25 to 1.93, NNH 3). Risperidone was no more or less likely than haloperidol to cause sexual problems such as erectile dysfunction (n=106, 2 RCTs, RR 1.55 CI 0.58 to 4.20). Finally, some results found risperidone was more likely to cause rhinitis than conventional antipsychotics (n=656, 3 RCTs, RR1.99 CI 1.24 to 3.19, NNH 3). Risperidone may be more acceptable to those with schizophrenia than older antipsychotics and have marginal benefits in terms of limited clinical improvement. Its adverse effect profile may be better than haloperidol. With the addition of more studies to this review, the publication bias evident in previous versions is no longer a significant issue. Any marginal benefits this drug may have have to be balanced against its greater cost and increased tendency to cause side effects such as weight gain. Recent important longer term

    Heart failure places a significant economic burden on health care. Acute heart failure requires hospitalization and often frequent re-hospitalization in expensive wards where vasoactive rescue therapy is often added on top of standard medications. In these lean times, there is a growing need for cost-effective therapeutic options that supply superior support and in addition shorten the length of stay in hospital and reduce re-hospitalization rates. The inodilator levosimendan represents the latest addition to the vasoactive treatments of acute heart failure patients, and it appears to meet these expectations. Our aim was to answer the question whether the treatment efficacy of levosimendan - when selected as therapy for patients hospitalized for acute heart failure - brings savings to hospitals in various European countries representing different economies. We took a conservative approach and selected some a fortiori arguments to simplify the calculations. We selected seven European countries to represent different economies: Italy, Spain, Greece, Germany, Sweden, Finland and Israel. Data on the costs of medications and on the cost per day were collected and fed in a simple algorithm to detect savings. These saving varied from country to country, from a minimum of €0.50 in Germany to a maximum of €354.64 in Sweden. The use of levosimendan as a therapy for patients hospitalized for acute heart failure provides a net saving to hospitals driven by a reduction in the length of hospital stay. This finding is true in each of the countries considered in this study. Copyright © 2015. Published by Elsevier Ireland Ltd.

    In Cardiovascular Rehabilitation the increasing inpatients complexity suggests the necessity to develop screening methods which allow to identify those patients that require a psychological intervention. A Psycho-Cardiological Schedule (PCS) was developed with the aim of detecting the critical situation indicators or the presence of psychological, social and cognitive problems. The PCS, compiled by a nurse or cardiologist in collaboration with a psychologist, allows to assess the need for a deeper psychological examination, clinical and/or with tests. Aim of the present study is to identify the convergence levels among the observational and anamnestic data of the PCS collected by a nurse and the clinical and/or test data of the psychological deeper assessment. Among the 87 patients recruited in January-February 2010, 28 (aged 53.5 +/- 12.6, M = 20, F = 8) fulfilled the criteria for a deeper psychological examination: age psychological/behavioural problems, neuropsychological disorders, low adherence to prescriptions, inadequate disease knowledge/representation. From data comparisons emerged convergence levels with 100% concordance as to smoke habits and problems in social-family support. High convergence levels also resulted as to emotional and/or behavioural problems (92.8%) and inadequate adherence to prescriptions (89.3%). Lower levels of concordance (82.1%) emerged when considering disease knowledge/representation, issues specifically linked to cognition and subjective illness experience, not directly detectable from behaviour. our data confirm the synergic efficacy of the two evaluations: the Psycho-Cardiological Schedule reliably identifies the problematic macro-categories, mainly if they are characterized by behavioural indicators, which facilitate the detection. The psychological approach appears more suitable for better specifing macro-categories characteristics and for detecting critical aspects not overt but not less important, providing therefore advice

    Full Text Available Abstract Background Although popular tattoos are often regretted later on for different reasons. Nevertheless, tattoo removal is a complicated and costly procedure seldom providing satisfactory results. The aim of this study was to investigate the awareness of the implications of tattoo removal among a substantial sample of Italian secondary school adolescents. Findings Students were recruited by a stratified convenience sample and surveyed by a self administered questionnaire. Logistic regression analysis was performed, reporting adjusted Odds Ratios (OR, with 95% Confidence Interval (CI. 4,277 pupils returned a usable questionnaire. Piercings were more frequently undertaken than tattoos. Only 40% of the respondents were aware of the issues related to tattoo removal. Males and pupils with younger fathers were less likely to be aware, whereas students satisfied with their physical appearance and those with a positive attitude towards body art were more likely to be aware. Conclusions Male adolescents with younger fathers can be regarded as the ideal target of corporate health education programs driven by school counsellors and primary care physicians.

    Sudden cardiac death (SCD) is a common mode of death in hypertrophic cardiomyopathy (HCM), but identification of patients who are at a high risk of SCD is challenging as current risk stratification guidelines have never been formally validated. The objective of this study was to assess the power of the 2003 American College of Cardiology (ACC)/European Society of Cardiology (ESC) and 2011 ACC Foundation (ACCF)/American Heart Association (AHA) SCD risk stratification algorithms to distinguish high risk patients who might be eligible for an implantable cardioverter defibrillator (ICD) from low risk individuals. We studied 1606 consecutively evaluated HCM patients in an observational, retrospective cohort study. Five risk factors (RF) for SCD were assessed: non-sustained ventricular tachycardia, severe left ventricular hypertrophy, family history of SCD, unexplained syncope and abnormal blood pressure response to exercise. During a follow-up period of 11 712 patient years (median 6.6 years), SCD/appropriate ICD shock occurred in 20 (3%) of 660 patients without RF (annual rate 0.45%), 31 (4.8%) of 636 patients with 1 RF (annual rate 0.65%), 27 (10.8%) of 249 patients with 2 RF (annual rate 1.3%), 7 (13.7%) of 51 patients with 3 RF (annual rate 1.9%) and 4 (40%) of 10 patients with ≥4 RF (annual rate 5.0%). The risk of SCD increased with multiple RF (2 RF: HR 2.87, p≤0.001; 3 RF: HR 4.32, p=0.001; ≥4 RF: HR 11.37, p<0.0001), but not with a single RF (HR 1.43 p=0.21). The area under time-dependent receiver operating characteristic curves (representing the probability of correctly identifying a patient at risk of SCD on the basis of RF profile) was 0.63 at 1 year and 0.64 at 5 years for the 2003 ACC/ESC algorithm and 0.61 at 1 year and 0.63 at 5 years for the 2011 ACCF/AHA algorithm. The risk of SCD increases with the aggregation of RF. The 2003 ACC/ESC and 2011 ACCF/AHA guidelines distinguish high from low risk individuals with limited power.

    The purpose of the present paper is to compute fissile 239 Pu material by supposed typical fusion reactor operation to make the fuel requirement for other purposes (e.g. MOX fissile fuel, etc.). It is assumed that there is a fusion reactor has a cylindrical geometry and uses uniformly distributed deuterium-tritium as fuel so that neutron wall load is taken at 10(MW)/(m 2 ) . Moreover, the reactor core is surrounded by six suggested blankets to make best performance of the physical conditions described herein. We determined neutron flux in each considered blanket as well as tritium self-sufficiency using two groups neutron energy and then computation is followed by the MCNP-4C code. Finally, material depletion according to a set of dynamical coupled differential equations is solved to estimate 239 Pu production rate. Produced 239 Pu is compared with two typical fission reactors to find performance of plutonium breeding ratio in the case of the fusion reactor. We found that 0.92% of initial U is converted into fissile Pu by our suggested fusion reactor with thermal power of 3000 MW. For comparison, 239 Pu yield of suggested large scale PWR is about 0.65% and for LMFBR is close to 1.7%. The results show that the fusion reactor has an acceptable efficiency for Pu production compared with a large scale PWR fission reactor type

    The purpose of this paper is to audit the active discharge (DC) planning process in a general cardiology clinic, by pre-assessing patients' medical notes and highlighting those suitable for potential DC to the clinic physician. The cardiology clinical nurse specialist (CNS) identified patients' for nine- to 12-month return visits one week prior to attendance. The previous consultation letter was accessed and information was documented by the CNS in the medical record. The key performance indicator (KPI) used was patient DCs for each clinic visit. The process was audited at three separate times to reflect recommended action carried out. The CNS pre-assessment and presence at the clinics significantly increased total DCs during the first period compared to usual care, 11 vs 34 per cent (p audit period, DCs fell (9 per cent) with a reduction in CNS pre-assessed DCs (10 per cent). Recommendations were implemented. The process was continued by clinic administration staff, colour coding all nine- to 12-month returns, resulted in a 19 per cent DC rate in 2012. CNS pre-assessment and highlighting DC suitability increased the number of patient DCs. As the CNS presence at the clinic reduced so did the rate of DC. Specific personnel need to be responsible for monitoring and reminding staff of the process; this does not always have to be medical or nursing. Implementing positive discharging procedures is aimed at improving quality, increasing efficiency and accessibility of services for patients. This audit describes a process to promote DC planning from cardiology outpatients.

    The practice of interventional cardiology differs between countries and regions. In this study we report the results of the first nation-wide long-term comparison of interventional cardiology in two countries using a common web-based registry. The Swedish Coronary Angiography and Angioplasty Registry (SCAAR) was used to prospectively and continuously collect background-, quality-, and outcome parameters for all coronary angiographies (CA) and percutaneous coronary interventions (PCI) performed in Iceland and Sweden during one year. The rate of CA per million inhabitants was higher in Iceland than in Sweden. A higher proportion of patients had CA for stable angina in Iceland than in Sweden, while the opposite was true for ST elevation myocardial infarction. Left main stem stenosis was more commonly found in Iceland than in Sweden. The PCI rate was similar in the two countries as was the general success rate of PCI, achievement of complete revascularisation and the overall stent use. Drug eluting stents were more commonly used in Iceland (23% vs. 19%). The use of fractional flow reserve (0.2% vs. 10%) and the radial approach (0.6% vs. 33%) was more frequent in Sweden than in Iceland. Serious complications and death were very rare in both countries. By prospectively comparing interventional cardiology in two countries, using a common web based registry online, we have discovered important differences in technique and indications. A discovery such as this can lead to a change in clinical practice and inspire prospective multinational randomised registry trials in unselected, real world populations.

    Objectives This study assesses practice variation of secondary prevention medication prescription among coronary artery disease (CAD) patients treated in outpatient practices participating in the NCDR® PINNACLE Registry®. Background Among patients with CAD, secondary prevention with a combination of beta-blockers, angiotensin converting enzyme inhibitors/angiotensin receptor blockers, and statins reduces cardiac mortality and myocardial infarction (MI). Accordingly, every CAD patient should receive the combination of these medications for which they are eligible. However, little is known about current prescription patterns of these medications and the variation in use among outpatient cardiology clinics. Methods Using data from NCDR® PINNACLE Registry®, a national outpatient cardiology practice registry, we assessed medication prescription patterns among eligible CAD patients between July 2008 and December 2010. Overall rates of prescription and variation by practice were calculated, adjusting for patient characteristics. Results Among 156,145 CAD patients in 58 practices, 103,830 (66.5%) were prescribed the optimal combination of medications for which they were eligible. The median rate of optimal combined prescription by practice was 73.5% and varied from 28.8% to 100%. After adjustment for patient factors, the practice median rate ratio for prescription was 1.25 (95% CI 1.2,1.32), indicating a 25% likelihood that 2 random practices would differ in treating identical CAD patients. Conclusions Among a national registry of CAD patients treated in outpatient cardiology practices, over one-third of patients failed to receive their optimal combination of secondary prevention medications. Significant variation was observed across practices, even after adjusting for patient characteristics, suggesting that quality improvement efforts may be needed to support more uniform practice.

    Patient safety and emergency department (ED) functionality are compromised when inefficient coordination between hospital departments impedes ED patients' access to inpatient cardiac care. The objective of this study was to determine how bed demand from competing cardiology admission sources affects ED patients' access to inpatient cardiac care. A stochastic discrete event simulation of hospital patient flow predicted ED patient boarding time, defined as the time interval between cardiology admission request to inpatient bed placement, as the primary outcome measure. The simulation was built and tested from 1 year of patient flow data and was used to examine prospective strategies to reduce cardiology patient boarding time. Boarding time for the 1,591 ED patients who were admitted to the cardiac telemetry unit averaged 5.3 hours (median 3.1, interquartile range 1.5-6.9). Demographic and clinical patient characteristics were not significant predictors of boarding time. Measurements of bed demand from competing admission sources significantly predicted boarding time, with catheterization laboratory demand levels being the most influential. Hospital policy required that a telemetry bed be held for each electively scheduled catheterization patient, yet the analysis revealed that 70.4% (95% CI 51.2-92.5) of these patients did not transfer to a telemetry bed and were discharged home each day. Results of simulation-based analyses showed that moving one afternoon scheduled elective catheterization case to before noon resulted in a 20-minute reduction in average boarding time compared to a 9-minute reduction achieved by increasing capacity by one additional telemetry bed. Scheduling and bed management practices based on measured patient transfer patterns can reduce inpatient bed blocking, optimize hospital capacity, and improve ED patient access.

    Full Text Available Objective: Survival rates for childhood acute lymphoblastic leukemia (ALL have significantly improved and late effects of therapy have been important in the follow-up of survivors. The objective of this study is to identify the endocrinological and cardiological late effects of ALL patients treated in our pediatric hematology unit. Materials and Methods: Patients treated for ALL with BFM protocols after at least 5 years of diagnosis and not relapsed were included in the study. Endocrinological late effects (growth failure, obesity, insulin resistance, dyslipidemia, thyroid gland disorders, osteopenia/osteoporosis, and pubertal disorders and cardiological late effects were evaluated. The study group was evaluated with anthropometric measurements, body mass index, and laboratory testing of fasting glucose, insulin, serum lipids, thyroid functions, and bone mineral densities. Echocardiography and pulsed wave Doppler imaging were performed for analysis of cardiac functions. Results: Of the 38 ALL survivors, at least 1 adverse event occurred in 23 (60%, with 8 of them (21% having multiple problems. Six (16% of the survivors were obese and 8 (21% of them were overweight. Subjects who were overweight or obese at the time of diagnosis were more likely to be overweight or obese at last follow-up. Obesity was more frequently determined in patients who were younger than 6 years of age at the time of diagnosis. Insulin resistance was observed in 8 (21% subjects. Insulin resistance was more frequently seen in subjects who had family history of type 2 diabetes mellitus. Hyperlipidemia was detected in 8 (21% patients. Hypothyroidism or premature thelarche were detected in 2 children. Two survivors had osteopenia. Cardiovascular abnormalities occurred in one of the subjects with hypertension and cardiac diastolic dysfunction. Conclusion: We point out the necessity of follow-up of these patients for endocrinological and cardiological late effects, since at least

    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)

    Positron emission tomography (PET) and X-ray computed tomography (CT) performed with PET/CT cameras allow us to obtain concurrently information on the presence and degree of alterations of myocardial perfusion and metabolism and on coronary arteries calcification. Furthermore, by gated myocardial perfusion studies, PET may provide crucial information on regional coronary blood flow reserve and endothelial dysfunction. A number of recent papers provide some insight on the potential of PET/CT in cardiology and in the assessment of various cardiovascular diseases including various types of vasculitis and metabolic diseases.

    The burden of cardiovascular diseases (CVDs) in the world is ever growing. They represent the first cause of death worldwide and in Latin America. Nuclear cardiology has a well-established role in the management of patient with CVDs and is being increasingly integrated into the healthcare systems in the region. However, there remains variability as to the infrastructure available across the countries, in terms of existing technology, radiopharmaceuticals, and human resources. The approximate number of gamma (γ) cameras in the region is 1348, with an average of 2.25 per million population; Argentina and Brazil having the largest number. Nearly 80% of the existing cameras are single-photon emission tomography (SPECT), of which 8% are hybrid SPECT-CT systems. Positron emission tomography technology is steadily increasing, and currently, there is an average of 0.25 scanners per million inhabitants, indicating that there is a potential to expand the capacities in order to cover the needs. Four countries have nuclear reactors for research purposes, which allow the production of technetium-99 m (Argentina, Chile, Mexico and Peru), while four (Argentina, Brazil, Cuba, and Mexico) assemble 99 Mo- 99m Tc generators. As for the nuclear cardiology studies, about 80% of studies performed are gated SPECT myocardial perfusion imaging; less than 10% are multi-gated acquisition (mainly for evaluation of cardiac toxicity in cancer patients), and the other 10% correspond to other types of studies, such as viability detection, and adrenergic innervation studies with 123 I-MIBG. Physical stress is preferred, when possible, based on the clinical condition of the patient. Regarding human resources, there is an average of 1.1 physicians and 1.3 technologists per γ camera, with 0.1 medical physicists and 0.1 radiopharmacists per center in the region. The future of nuclear cardiology in Latin America and the Caribbean is encouraging, with great potential and possibilities for growth

    Full Text Available Cardiovascular diseases are the leading causes of mortality and morbidity in Brazil. The primary and secondary preventions of those diseases are a priority for the health system and require multiple approaches to increase their effectiveness. Biomarkers are tools used to more accurately identify high-risk individuals, to speed the diagnosis, and to aid in treatment and prognosis determination. This review aims to highlight the importance of biomarkers in clinical cardiology practice, and to raise relevant points of their use and the promises for the coming years. This document was divided into two parts, and this first one discusses the use of biomarkers in specific cardiomyopathies and heart failure.

    The objective of this article is to present initial occupational dose values using digital active personal dosimeters for medical staff during adult interventional cardiology procedures in a public hospital in Chile. Personal dose equivalent Hp(10) over the lead apron of physician, nurse and radiographer were measured during 59 procedures. Mean values of occupational dose Hp(10) per procedure were 47.6, 6.2 and 4.3 μSv for physician, nurse and radiographer, respectively. If no protective tools are used, physician dose can exceed the new eye lens dose limit.

    Many patients who receive medical interventional cardiology procedures at a tertiary hospital live outside the metropolitan area and may experience fragmentation in care, less emotional support by family members, inaccurate and delayed communication, and lack of educational follow-up on discharge from the hospital. A clinical pathway titled "Heart Health Care Patterns" was developed to link acute phase, recovery phase, rehabilitation phase, and enhancement/maintenance phase. The 12-month clinical pathway combines Gordon's Functional Health Patterns and the Omaha System developed by the Omaha Visiting Nurse Association. The rating scale for outcomes assesses the patient at different phases to provide objective data and information throughout the year.

    The renewal of radiological materials has contributed to reduce significantly the doses received by the personnel. The installations of low shutters and lead windows give an important potential of reduction of doses received by the physicians. For the medical and para medical personnel, a modification of working habits must lead to an important exposure reduction. To summarize, the medical and para medical personnel in cardiology has at one s disposal all the means allowing to reach the objective of dose constraints. The radiation protection optimization now depends on every concerned actor. (N.C.)

    After a discussion of several publications about patient dosimetry in interventional cardiology, the author recalls that the in vivo assessment of the dose received by some organs is uneasy because invasive. Therefore, the assessment requires the use of physical or mathematical dosimetric phantoms which simulate patient morphology as well as the incident photon attenuation phenomenon. He evokes some characteristics and applications of these phantoms. He outlines the different sources and origins of the dose received by the patient, and discusses results obtained by collecting data from 177 patients submitted to diagnosis or therapeutic procedures

    Acute ischemic stroke is a catastrophic cardiovascular disease with frequent cardiac causes and cerebral consequences, thus the close cooperation between neurologists and cardiologists is necessary for the optimal patient management. Furthermore, recent randomized trials demonstrated, that catheter-based thrombectomy (CBT) is the most effective treatment for properly selected patients. Interventional cardiology with its widespread non-stop services for acute myocardial infarction can fill the existing gaps in coverage of population needs with neurointerventional services. Thus, a new future medical subspecialization may emerge: neurocardiology or cardioneurology.

    110 patients classified as physically disabled as a consequence of myocardial infarction were reinvestigated by means of nuclear cardiological methods. Resting 201 Tl 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 201 Tl scintigraphy and radionuclide ventriculography in assessments of the degree of physical disability after myocardial infarction. (author) 15 refs.; 3 tabs

    Considerable work has shown the benefits for psychological health of being gender typed (i.e., perceiving oneself in ways that are consistent with one's sex). Nevertheless, little is known about the reasons for the link. In two studies of young adults (total N = 673), we studied (1) the ways in which gender typing is predicted from gender-related interests and personal qualities, and (2) links between gender typing and adjustment (self-esteem and negative emotionality). In the first study, gender typicality was positively predicted by a variety of gender-related characteristics and by communal traits, a female-typed characteristic; gender typicality was also positively associated with adjustment. To clarify the role of communality in predicting gender typicality and its link with adjustment, we conducted a follow-up study examining both gender typicality and "university typicality." Gender typicality was again predicted by gender-related characteristics and communality, and associated with adjustment. Further, university typicality was also predicted by communality and associated with adjustment. Mediation analyses showed that feelings of communality were partly responsible for the links between gender/university typicality and adjustment. Thus, the psychological benefits suggested to accrue from gender typicality may not be specific to gender, but rather may reflect the benefits of normativity in general. These findings were discussed in relation to the broader literature on the relation between identity and adjustment.

    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

    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.

    In recent years, athletic participation has more than doubled in all major demographic groups, while simultaneously, children and adults with established heart disease desire participation in sports and exercise. Despite conferring favorable long-term effects on well-being and survival, exercise can be associated with risk of adverse events in the short term. Complex individual cardiovascular (CV) demands and adaptations imposed by exercise present distinct challenges to the cardiologist asked to evaluate athletes. Here, we describe the evolution of sports and exercise cardiology as a unique discipline within the continuum of CV specialties, provide the rationale for tailoring of CV care to athletes and exercising individuals, define the role of the CV specialist within the athlete care team, and lay the foundation for the development of Sports and Exercise Cardiology in the United States. In 2011, the American College of Cardiology launched the Section of Sports and Exercise Cardiology. Membership has grown from 150 to over 4,000 members in just 2 short years, indicating marked interest from the CV community to advance the integration of sports and exercise cardiology into mainstream CV care. Although the current athlete CV care model has distinct limitations, here, we have outlined a new paradigm of care for the American athlete and exercising individual. By practicing and promoting this new paradigm, we believe we will enhance the CV care of athletes of all ages, and serve the greater athletic community and our nation as a whole, by allowing safest participation in sports and physical activity for all individuals who seek this lifestyle.

    Full Text Available OBJECTIVE: To evaluate the management of patients complaining of high blood pressure (BP in a cardiological emergency room. METHODS: Patients referred to the cardiological emergency room with the main complaint of high blood pressure were consecutively selected. The prescriptions and the choice of antihypertensive drugs were assessed. The classification of these patients as hypertensive emergencies or pseudoemergencies, according to the physician who provided initial care, was recorded. RESULTS: From a total of 858 patients presenting to the emergency room, 80 (9.3% complained of high BP, and 61 (76.3% received antihypertensive drugs. Sublingual nifedipine was the most commonly used drug (59%. One patient received intravenous medication, one patient was hospitalized and 6 patients (7.5% were classified as hypertensive emergencies or pseudoemergencies. CONCLUSION: High BP could seldom be classified as a hypertensive emergency or pseudoemergency, even though it was a frequent complaint (9.3% of visits. Currently, the therapeutic approach is not recommended, even in specialized clinics.

    Analysis of the underlying causes of death can develop action plans for prevention of death that could be avoided. The aim of our study was to analyse the causes of cardiovascular deaths in the cardiology department of Yalgado Ouedraogo University Hospital. The study was a descriptive retrospective study over a 24 month period among patients who died in the department. Prevalence of death in the cardiology department was of 13.2%. Sex ratio was of 1.2 and 72.7% of patients were residing in Ouagadougou. Mean age of patients was 56.1 years and 59.4% of patients were under 65 years old. Hypertension was the major cardiovascular risk factor (46.1%) and 27.4% of patients had a medical history of dilated cardiomyopathy. Cardiogenic shock was the immediate cause of death in 55.5% of cases and the initial cause of death was hypertension and its complications in 46.1% of cases. Death was not notified in 18% of cases and no death had been medically certified. Death statistics are the most reliable data for public health interventions. However, it is necessary to establish an effective method of data gathering according to the WHO standards in order to facilitate international comparison.

    No scientific assessment of the theoretical teaching of cardiology in France is available. To analyse the impact of the available teaching modalities on the theoretical knowledge of French residents in cardiology. Electronic questionnaires were returned by 283 residents. In the first part, an inventory of the teaching/learning methods was taken, using 21 questions (Yes/No format). The second part was a knowledge test, comprising 15 multiple-choice questions, exploring the core curriculum. Of the 21 variables tested, four emerged as independent predictors of the score obtained in the knowledge test: access to self-assessment (P=0.0093); access to teaching methods other than lectures (P=0.036); systematic discussion about clinical decisions (P=0.013); and the opportunity to prepare and give lectures (P=0.039). The fifth variable was seniority in residency (P=0.0003). Each item of the knowledge test was analysed independently: the score was higher when teaching the item was driven by reading guidelines and was lower if the item had not been covered by the programme (Pcardiology by involving students in the training, by using teaching methods other than lectures and by facilitating access to self-assessment.

    The term "onco-cardiology" has been used in reference to cardiotoxicity in the treatment of malignant disease. In actual clinical situations, however, cardiovascular disease (CVD) associated with malignant disease and the concurrence of atherosclerotic disease with malignant disease are commonly observed, complicating the course of treatment. Patients with malignant disease associated with coronary artery disease often die from the cardiovascular disease, so it is essential to classify these disease states. Additionally, the prevalence of these classifications makes it easy to manage patients with malignant disease and coronary artery disease. We divided the broad field of onco-cardiology into 4 classifications based on clinical scenarios (CSs): CS1 represents the so-called paraneoplastic syndrome. CS2 represents cardiotoxicity during treatment of malignant diseases. CS3 represents the concurrence of atherosclerotic disease with malignant disease, and CS4 represents cardiovascular disease with benign tumors. This classification facilitates the management of patients with malignant disease and coronary artery disease by promoting not only the primary but also the secondary prevention of CVD.

    Evidence-based medicine has contributed substantially to the quality of medical care in pediatric and adult cardiology. However, our impression from the bedside is that a substantial number of Cochrane reviews generate inconclusive data that are of limited clinical benefit. We performed a systematic synopsis of Cochrane reviews published between 2001 and 2015 in the field of pediatric cardiology. Main outcome parameters were the number and percentage of conclusive, partly conclusive, and inconclusive reviews as well as their recommendations and their development over three a priori defined intervals. In total, 69 reviews were analyzed. Most of them examined preterm and term neonates (36.2%), whereas 33.3% included also non-pediatric patients. Leading topics were pharmacological issues (71.0%) followed by interventional (10.1%) and operative procedures (2.9%). The majority of reviews were inconclusive (42.9%), while 36.2% were conclusive and 21.7% partly conclusive. Although the number of published reviews increased during the three a priori defined time intervals, reviews with "no specific recommendations" remained stable while "recommendations in favor of an intervention" clearly increased. Main reasons for missing recommendations were insufficient data (n = 41) as well as an insufficient number of trials (n = 22) or poor study quality (n = 19). There is still need for high-quality research, which will likely yield a greater number of Cochrane reviews with conclusive results.

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

    2010-12-01

    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.

    The prevalence of heart failure remains high and represents the highest disease burden in Spain. Heart failure units have been developed to systematize the diagnosis, treatment, and clinical follow-up of heart failure patients, provide a structure to coordinate the actions of various entities and personnel involved in patient care, and improve prognosis and quality of life. There is ample evidence on the benefits of heart failure units or programs, which have become widespread in Spain. One of the challenges to the analysis of heart failure units is standardization of their classification, by determining which "programs" can be identified as heart failure "units" and by characterizing their complexity level. The aim of this article was to present the standards developed by the Spanish Society of Cardiology to classify and establish the requirements for heart failure units within the SEC-Excellence project.

    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 1m 2 , 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

    Mexico has been positioned as the country with the highest mortality attributed to myocardial infarction among the members of the Organization for Economic Cooperation and Development. This rate responds to multiple factors, including a low rate of reperfusion therapy and the absence of a coordinated system of care. Primary angioplasty is the reperfusion method recommended by the guidelines, but requires multiple conditions that are not reached at all times. Early pharmacological reperfusion of the culprit coronary artery and early coronary angiography (pharmacoinvasive strategy) can be the solution to the logistical problem that primary angioplasty rises. Several studies have demonstrated pharmacoinvasive strategy as effective and safe as primary angioplasty ST-elevation myocardial infarction, which is postulated as the choice to follow in communities where access to PPCI is limited. The Mexico City Government together with the National Institute of Cardiology have developed a pharmaco-invasive reperfusion treatment program to ensure effective and timely reperfusion in STEMI. The model comprises a network of care at all three levels of health, including a system for early pharmacological reperfusion in primary care centers, a digital telemedicine system, an inter-hospital transport network to ensure primary angioplasty or early percutaneous coronary intervention after fibrinolysis and a training program with certification of the health care personal. This program intends to reduce morbidity and mortality associated with myocardial infarction. Copyright © 2016 Instituto Nacional de Cardiología Ignacio Chávez. Publicado por Masson Doyma México S.A.

    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)

    The purpose of this review is to explore the paradigm shift in healthcare delivery that will need to take place over the next few years away from an emphasis on supply-driven health care to better quality transparent-driven health care whose focus is on the consumer's best interest. The current healthcare system is fragmented and costs continue to rise. The best way to contain costs is to improve quality to the consumer, the patient. Physicians and hospitals need to align in a team-based approach that allows physicians to understand current costs and how to strive toward a focus on healthcare outcomes. Pediatric cardiology is a unique discipline that cares for patients with complex congenital conditions that will span their lifetime and also involves not just cardiology but surgery, intensive care, anesthesia, nursing, and a host of inpatient and ambulatory services. Understanding what matters to the patient and his/her family and presenting quality outcomes in a transparent fashion will gradually allow a shift to take place away from physician visits, tests ordered, and procedures performed. This can only be achieved with physicians, given the appropriate tools to understand costs, value, and outcomes and models where the hospitals and physicians are aligned. The transformation to a value-based healthcare system is beginning and pediatric cardiologists need to be educated, given the appropriate resources, receive appropriate feedback, and patients need to be part of the solution so that care providers can understand what matters most to them.

    The use of rigorous scientific methods has contributed towards developing scientific articles of excellent methodological quality. This has made it possible to promote their citation and increase the impact factor. Brazilian periodicals have had to adapt to certain quality standards demanded by these indexing organizations, such as the content and the number of original articles published in each issue. This study aimed to evaluate the methodological adequacy of two Brazilian periodicals within the field of cardiology that are indexed in several databases and freely accessible through the Scientific Electronic Library Online (SciELO), and which are now indexed by the Web of Science (Institute for Scientific Information, ISI). Descriptive study at Brazilian Cochrane Center. All the published articles were evaluated according to merit assessment (content) and form assessment (performance). Ninety-six percent of the articles analyzed presented study designs that were adequate for answering the objectives. These two Brazilian periodicals within the field of cardiology published methodologically adequate articles, since they followed the quality standards. Thus, these periodicals can be considered both for consultation and as vehicles for publishing future articles. For further analyses, it is essential to apply other indicators of scientific activity such as bibliometrics, which evaluates quantitative aspects of the production, dissemination and use of information, and scientometrics, which is also concerned with the development of science policies, within which it is often superimposed on bibliometrics.

  7. Improving Access to Pediatric Cardiology in Cape Verde via a Collaborative International Telemedicine Service.

    This paper addresses the role of international telemedicine services in supporting the evacuation procedures from Cape Verde to Portugal, enabling better quality and cost reductions in the management of the global health system. The Cape Verde, as other African countries, health system lacks many medical specialists, like pediatric cardiologists, neurosurgery, etc. In this study, tele-cardiology shows good results as diagnostic support to the evacuation decision. Telemedicine services show benefits while monitoring patients in post-evacuation, helping to address the lack of responsive care in some specialties whose actual use will help save resources both in provision and in management of the evacuation procedures. Additionally, with tele-cardiology collaborative service many evacuations can be avoided whereas many cases will be treated and followed locally in Cape Verde with remote technical support from Portugal. This international telemedicine service enabled more efficient evacuations, by reducing expenses in travel and housing, and therefore contributed to the health system's improvement. This study provides some evidence of how important telemedicine really is to cope with both the geography and the shortage of physicians.

    In 1999 Romania started its health care reform by promulgating the Health Insurance Law. A functional and efficient health care system needs procedures for monitoring and evaluation of the medical services, communication between different service providers and entities involved in the system, integration and availability of the information. The final goal is a good response to the needs and demands of the patients and of the real life. For this project we took into account, on one hand, the immediate need for computerized systems for the health care providers and, on the other hand, the large number of trials and experiments with health smart cards across Europe. Our project will implement a management system based on electronic patient records to be used in all cardiology clinics and will experiment the health smart cards, will promote and demonstrate the capabilities of the smart card technology. We focused our attention towards a specific and also critical category of patients, those with heart diseases, and also towards a critical sector of the health care system--the emergency care. The patient card was tested on a number of 150 patients at a cardiology clinic in Bucharest. This was the first trial of a health smart card in Romania.

    Everolimus, a proliferation signal inhibitor in the mammalian target of rapamycin (mTOR) drug class, has many clinical applications, including in organ transplantation, oncology, and cardiology. It currently has United States Food and Drug Administration (FDA) approval for prophylaxis against rejection in de novo renal transplant recipients, treatment of renal cell carcinoma, and use as a drug-eluting stent. To review the pharmacology, pharmacokinetics, efficacy, and safety of everolimus, we performed a search of the MEDLINE database (January 1997-April 2010) for all English-language articles of in vitro and in vivo studies that evaluated everolimus, as well as abstracts from recent scientific meetings and the manufacturer. In transplantation, everolimus demonstrates immunosuppressive properties and has been used to prevent acute rejection in cardiac, liver, lung, and renal transplant recipients. It appears that this agent may be potent enough to allow for the minimization or removal of calcineurin inhibitors in the long-term management of renal transplant recipients. In oncology, everolimus has been proven effective for the management of treatment-resistant renal cell carcinoma. In cardiology, everolimus is available as a drug-coated stent and is used in percutaneous coronary interventions for prevention of restenosis. In transplant recipients and patients with renal cell carcinoma, everolimus appears to have an extensive adverse-event profile. The pharmacologic properties of everolimus differentiate this agent from other drugs used in these clinical areas, and its pharmacokinetic properties differentiate it from sirolimus.

    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)

    The first writings on cardioangiology found in public and private libraries of New Spain from the xvi century to the first century of the Independent period in Mexico are mentioned. These go from the truly incunabular ones, books printed until the year 1500, to the physiology treatises published by European authors in the xvii and xviii centuries, as well as the cardiology texts from French authors of the first half of the xix century. The writings were depicted in the catalogs of the University library, founded in 1762, as well as in the library of a master builder of the Metropolitan Cathedral of the xvii century and that of a physician of the xviii century, Dr. José Ignacio Bartolache. The latter, in turn, edited for a brief period, from October 1772 to February 1773, a scientific-medical journal, «Mercurio Volante», which was the first scientific-hebdomadary publication in the Americas. Likewise, in the libraries of New Spain, several European scientific journals could be found, such as the one edited by the abbot Rozier, in which the initial writings of Lavoisier appeared. The exchange of ideas and knowledge, pointed out herein, attests to the always enthused interest of given individuals from New Spain on the boundless and passionate domains of cardioangiology.

    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.

  13. Musical Mnemonics Enhance Verbal Memory in Typically Developing Children

    Full Text Available The purpose of this study was to compare the effects of musical mnemonics vs. spoken word in training verbal memory in children. A randomized control trial of typically-developing 9–11 year old children was conducted using the Rey Auditory Verbal Learning Test (RAVLT, a test measuring a participant's ability to recall a list of 15 words over multiple exposures. Members of the group who listened to words sung to them recalled an average of 20% more words after listening to and recalling an interference list than members of the control group who listened to the same words spoken. This difference persisted, though slightly smaller (17% when participants recalled words after a 15-min waiting period. Additionally, group participants who listened to words sung demonstrated a higher incidence of words recalled in correct serial order. Key findings were all statistically significant at the P < 0.05 level. Enhanced serial order recall points to the musical pitch/rhythm structure enhancing sequence memory as a potential mnemonic mechanism. No significant differences were found in serial position effects between groups. The findings suggest that musical mnemonic training may be more effective than rehearsal with spoken words in verbal memory learning tasks in 9–11 year olds.

    Full Text Available We aimed to elucidate the dACC laterality in typically developing children and their sex/age-related differences with a sample of 84 right-handed children (6–16 years, 42 boys. We first replicated the previous finding observed in adults that gray matter density asymmetry in the dACC was region-specific: leftward (left > right in its superior part, rightward (left < right in its inferior part. Intrinsic connectivity analysis of these regions further revealed region-specific asymmetric connectivity profiles in dACC as well as their sex and age differences. Specifically, the superior dACC connectivity with frontoparietal network and the inferior dACC connectivity with visual network are rightward. The superior dACC connectivity with the default network (lateral temporal cortex was more involved in the left hemisphere. In contrast, the inferior dACC connectivity with the default network (anterior medial prefrontal cortex was more lateralized towards the right hemisphere. The superior dACC connectivity with lateral visual cortex was more distinct across two hemispheres in girls than that in boys. This connection in boys changed with age from right-prominent to left-prominent asymmetry whereas girls developed the connection from left-prominent to no asymmetry. These findings not only highlight the complexity and laterality of the dACC but also provided insights into dynamical structure–function relationships during the development.

    In the field of pediatrics and the related literature, the analysis of myocardial perfusion and ventricular function using myocardium scintiscanning and radionuclide ventriculography is a subject discussed rather rarely, in contrast to the medical examination of adult patients where this is a well-established method. The authors have so far not found any information on the use of scintiscanning methods for the diagnosis of idiopathic juvenile arteriosclerosis and hence take the opportunity to describe a case of recent application of this method. In addition, findings and results are discussed that speak in favour of the use of further nuclear-medical techniques in pediatric cardiology. (orig./MG) [de

    Typical aging is associated with diminished episodic memory performance. To improve our understanding of the fundamental mechanisms underlying this age-related memory deficit, we previously developed an integrated, cross-species approach to link converging evidence from human and animal research. This novel approach focuses on the ability to remember sequences of events, an important feature of episodic memory. Unlike existing paradigms, this task is nonspatial, nonverbal, and can be used to isolate different cognitive processes that may be differentially affected in aging. Here, we used this task to make a comprehensive comparison of sequence memory performance between younger (18–22 yr) and older adults (62–86 yr). Specifically, participants viewed repeated sequences of six colored, fractal images and indicated whether each item was presented “in sequence” or “out of sequence.” Several out of sequence probe trials were used to provide a detailed assessment of sequence memory, including: (i) repeating an item from earlier in the sequence (“Repeats”; e.g., ABADEF), (ii) skipping ahead in the sequence (“Skips”; e.g., ABDDEF), and (iii) inserting an item from a different sequence into the same ordinal position (“Ordinal Transfers”; e.g., AB3DEF). We found that older adults performed as well as younger controls when tested on well-known and predictable sequences, but were severely impaired when tested using novel sequences. Importantly, overall sequence memory performance in older adults steadily declined with age, a decline not detected with other measures (RAVLT or BPS-O). We further characterized this deficit by showing that performance of older adults was severely impaired on specific probe trials that required detailed knowledge of the sequence (Skips and Ordinal Transfers), and was associated with a shift in their underlying mnemonic representation of the sequences. Collectively, these findings provide unambiguous evidence that the

    Epidemiologic transition is taking place in every part of the world. Cardiovascular diseases became the most common cause of death accounting for 30% of deaths worldwide, with 80% of the burden now occurring in developing countries. The objective of the study was to assess the Pattern of disease among patients attending Cardiology outpatient department of a private hospital. The cross sectional descriptive type of observational study was conducted among 550 patients attending Cardiology outpatient department (COPD) of Sodesh Hospital, Mymensingh, Bangladesh from March 2016 to June 2016. All the new patients attending COPD of Sodesh Hospital were selected purposively for the study. Data were collected by interview, physical examination and laboratory investigations of patients using a case record form. Mean age of the patients was 45.1 years with a SD of 15.6 years. Among the patients male were 291(52.9%), a bit higher than the female 259(47.1%). It was observed that more than half of the patients (281, 51.1%) visited cardiologist with non-cardiac problems. Less than one third of the patients (169, 30.7%) attended with cardiac problems and 100(18.2%) patients visited with both cardiac and non-cardiac problems. Among the cardiac diseases and symptoms hypertension was on the top of the list 176(65.4%). Ischemic heart diseases was present in 35(13.0%) and palpitation was in 30(11.1%) patients. On the other hand among the non-cardiac diseases or presentations, 121(43.1%) patients had non-specific chest pain, 63(22.4%) had shortness of breath and 17(6.1%) had diabetes mellitus. Hypertension was found the most frequent cardiovascular disease (65.4%) followed by ischemic heart disease (13.0%). More than half (51.1%) of the patients visit cardiologist with non-cardiac problems. Screening at the level of general practitioner (GP) and appropriate referral system can reduce extreme burden of patients to the cardiologists in the Cardiology outpatient department.

    Cardiovascular diseases (CVD) are the leading cause of mortality both in men and women. In Europe, about 55% of all females' deaths are caused by CVD, especially coronary heart disease and stroke. Unfortunately, however, the risk of heart disease in women is underestimated because of the perception that women are 'protected' against ischaemic heart disease. What is not fully understood is that women during the fertile age have a lower risk of cardiac events, but this protection fades after menopause thus leaving women with untreated risk factors vulnerable to develop myocardial infarction, heart failure, and sudden cardiac death. Furthermore, clinical manifestations of ischaemic heart disease in women may be different from those commonly observed in males and this factor may account for under-recognition of the disease. The European Society of Cardiology has recently initiated an extensive 'Women at heart' program to coordinate research and educational initiatives on CVD in women. A Policy Conference on CVD in Women was one of the first steps in the development of this program. The objective of the conference was to collect the opinion of experts in the field coming from the European Society of Cardiology member countries to: (1) summarize the state-of-the-art from an European perspective; (2) to identify the scientific gaps on CVD in women; and (3) to delineate the strategies for changing the misperception of CVD in women, improving risk stratification, diagnosis, and therapy from a gender perspective and increasing women representation in clinical trials. The Policy Conference has provided the opportunity to review and comment on the current status of knowledge on CVD in women and to prioritize the actions needed to advance this area of knowledge in cardiology. In the preparation of this document we intend to provide the medical community and the stakeholders of this field with an overview of the more critical aspects that have emerged during the discussion.

    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

    We previously demonstrated that a pediatric cardiology boot camp can improve knowledge acquisition and decrease anxiety for trainees. We sought to determine if boot camp participants entered fellowship with a knowledge advantage over fellows who did not attend and if there was moderate-term retention of that knowledge. A 2-day training program was provided for incoming pediatric cardiology fellows from eight fellowship programs in April 2016. Hands-on, immersive experiences and simulations were provided in all major areas of pediatric cardiology. Knowledge-based examinations were completed by each participant prior to boot camp (PRE), immediately post-training (POST), and prior to the start of fellowship in June 2016 (F/U). A control group of fellows who did not attend boot camp also completed an examination prior to fellowship (CTRL). Comparisons of scores were made for individual participants and between participants and controls. A total of 16 participants and 16 control subjects were included.

Participants' knowledge improved with boot camp training (PRE 47 ± 11% vs. POST 70 ± 8%; p cardiology knowledge after the training program and had excellent moderate-term retention of that knowledge. Participants began fellowship with a larger fund of knowledge than those fellows who did not attend.

    A study of peak skin doses (PSDs) during neuroradiology and cardiology interventional procedures has been carried out using Gafchromic XR-RV2 film. Use of mosaics made from squares held in cling film has allowed doses to the head to be mapped successfully. The displayed cumulative air kerma (CAK) has been calibrated in terms of cumulative entrance surface dose (CESD) and results indicate that this can provide a reliable indicator of the PSD in neuroradiology. Results linking PSD to CESD for interventional cardiology were variable, but CAK is still considered to provide the best option for use as an indicator of potential radiation-induced effects. A CESD exceeding 3 Gy is considered a suitable action level for triggering follow-up of patients in neuroradiology and cardiology for possible skin effects. Application of dose action levels defined in this way would affect 8% of neurological embolisation procedures and 5% of cardiology ablation and multiple stent procedures at the hospitals where the investigations were carried out. A close relationship was observed between CESD and dose-area product (DAP) for particular types of procedure, and DAPs of 200-300 Gy cm 2 could be used as trigger levels where CAK readings were not available. The DAP value would depend on the mean field size and would need to be determined for each application.

    The complexity and potential biases involved in decision making have long been recognised and examined in both the aviation and business industries. More recently, the medical community have started to explore this concept and its particular importance in our field. Paediatric cardiology is a rapidly expanding field and for many of the conditions we treat, there is limited evidence available to support our decision-making. Variability exists within decision-making in paediatric cardiology and this may influence outcomes. There are no validated tools available to support and examine consistent decision-making for various treatment strategies in children with congenital heart disease in a multidisciplinary cardiology and cardiothoracic institution. Our primary objective was to analyse the complexity of decision-making for children with cardiac conditions in the context of our joint cardiology and cardiothoracic conference (JCC). Two paediatric cardiologists acted as investigators by observing the weekly joint cardiology-cardiothoracic surgery conference and prospectively evaluating the degree of complexity of decision-making in the management of 107 sequential children with congenital heart disease discussed. Additionally, the group consensus on the same patients was prospectively assessed to compare this to the independent observers. Of 107 consecutive children discussed at our JCC conference 32 (27%) went on to receive surgical intervention, 20 (17%) underwent catheterisation and 65 (56%) received medical treatment. There were 53 (50%) cases rated as simple by one senior observer, while 54 (50%) were rated as complex to some degree. There was high inter-observer agreement with a Krippendorff's alpha of ≥ 0.8 between 2 observers and between 2 observers and the group consensus as a whole for grading of the complexity of decision-making. Different decisions were occasionally made on patients with the same data set. Discussions revisiting the same patient, in

    Risk aversion is a potential unintended consequence of health care public reporting. In Part 1 of this review, four possible consequences of this phenomenon are discussed, including the denial of interventions to some high-risk patients, stifling of innovation, appropriate avoidance of futile interventions, and better matching of high-risk patients to more capable providers. We also summarize relevant observational clinical reports and survey results from cardiovascular medicine and surgery, the two specialties from which almost all risk aversion observations have been derived. Although these demonstrate that risk aversion does occur, the empirical data are much more consistent and compelling for interventional cardiology than for cardiac surgery.

    Summary Background Statins reduce coronary events in patients with coronary artery disease. Material/Methods Chart reviews were performed in 305 patients (217 men and 88 women, mean age 74 years) not treated with statins during the first year of being seen in an outpatient cardiology practice but subsequently treated with statins. Based on the starting date of statins use, the long-term outcomes of myocardial infarction (MI), percutaneous coronary intervention (PCI), and coronary artery bypass graft surgery (CABGS) before and after statin use were compared. Results Mean follow-up was 65 months before statins use and 66 months after statins use. MI occurred in 31 of 305 patients (10%) before statins, and in 13 of 305 patients (4%) after statins (pcardiology practice reduces the incidence of MI, PCI, and CABGS. PMID:22129898

    The World Congress of Paediatric Cardiology and Cardiac Surgery has survived with minimal assets and simple organisation. Each congress is special, taking on the humour, flavour, and culture of the organising country. It is hard work for a few organisers and money is hard to raise. The steering committee works closely, fairly, and successfully, and even though accused of being secretive and effete that does not matter. It is efficient and produces successful, happy world congresses, where all involved with the speciality are welcome. With so many "grown-ups" with congenital heart disease, it is no longer just a paediatric problem - maybe the name of this congress must change again. Regardless, the flag must fly on.

    From August 26th to 30th, the 2017 Annual Congress of the European Society of Cardiology (ESC 2017) was held in Barcelona, Spain. Despite the terrorism tradegy just before the ESC congress, the congress attracted many medical professionals from all over the world to discuss the recent topics in cardiovascular medicine in more than 500 sessions, including COMPASS (Cardiovascular OutcoMes for People using Anticoagulation StrategieS Trial), CANTOS (Canakinumab Anti-Inflammatory Thrombosis Outcomes Study), and ORION (which assessed the effect of a novel siRNA inhibitor to PCSK9 on reductions in low-density lipoprotein cholesterol). Japanese cardiologists and the Japanese Circulation Society greatly contributed to the congress. This report briefly introduces some late-breaking registry results, late-breaking clinical trials, and ESC Guidelines from the ESC 2017 Congress.

    The annual congress of the European Society of Cardiology (ESC) is the largest medical congress in Europe for this area of research and took place this year in Barcelona, Spain. The ESC Congress 2017 gathered more than 30,000 registered participants from over 140 countries together to share their knowledge in all cardiovascular fields, from basic science to management and prevention of cardiovascular diseases. The congress comprised 5 days of science and education with over 11,000 abstracts submitted, 500 expert sessions and over 200 exhibiting companies, making it the prime meeting platform for the profession. This year's ESC Congress Spotlight was "40 years of percutaneous coronary intervention (PCI)." PCI is a nonsurgical procedure used to treat narrowing of the coronary arteries of the heart found in coronary artery disease.

  12. Indications, applications and future prospects of diagnostic examinations in clinical cardiology

    Nowadays there are various kinds of diagnostic examinations in the field of clinical cardiology. In this field, information concerning structure, dimension (hypertrophy and dilatation) and cardiac function is essentially imporant. For the diagnosis of valvular and congenital heart diseases and of cardiomyopathy, ultrasonic examinations are more useful; for ischemic heart disease, nuclear medicine is superior. Angiocardiography provides us much information but it is invasive. A combination of an exercise-test with the examinations mentioned above is useful for the detection of left ventricular and coronary reserves. The determinants of left ventricular reserve, being related to the prognosis of the patients, can be analyzed by exercise echocardiography. Exercise echocardiography can reveal instantaneous changes in myocardial ischemia during exercise. Regional and global left ventricular performances revealed by exercise radionuclide angiocardiography can lead us to a new interpretation of an exercise ECG. (author)

    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 215 % 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 29 %. 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 (authors)

    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.

    As medical research techniques and quality have improved, it is apparent that cardiovascular problems could be better resolved by more strict experiment design. In fact, substantial time and resources should be expended to fulfill the requirements of high quality studies. Many worthy ideas and hypotheses were unable to be verified or proven due to ethical or economic limitations. In recent years, new and various applications and uses of databases have received increasing attention. Important information regarding certain issues such as rare cardiovascular diseases, women's heart health, post-marketing analysis of different medications, or a combination of clinical and regional cardiac features could be obtained by the use of rigorous statistical methods. However, there are limitations that exist among all databases. One of the key essentials to creating and correctly addressing this research is through reliable processes of analyzing and interpreting these cardiologic databases.

    The present study aimed to identify hygienic and motivational factors in the nursing work according to the Two-Factor Theory, as well as their relation with professional satisfaction/dissatisfaction. This exploratory-descriptive study involved nine nurses from the cardiology ward of a hospital in the interior of the State of São Paulo, between August and September 2013. A self-applied questionnaire was used, including open and closed questions. The data were categorized as hygienic and motivational. Results show the nurses' satisfaction with autonomy, work itself and teamwork, duties, content and responsibilities of the job. Dissatisfaction is related to career growth possibilities; work, political and administrative conditions at the institution, supervision and lack of institutional support. Satisfaction and dissatisfaction factors include relationships, acknowledgements and remuneration. Nurses' satisfaction is determined by multiple and often controversial factors.

    Nuclear cardiology methods for measuring ventricular function and pulmonary vs systemic blood flow (Qp/Qs) are attractive for long term experimental studies because they are invasive minimally and can be repeated frequently. We adapted the technique for use in a miniswine model of congestive heart failure secondary to a left to right shunt. Minor modifications in camera positioning were needed to obtain adequate studies in miniswine. A straight lateral position was best for first pass studies if Qp/Qs was to be measured and a 40 degree left anterior oblique view was best for gated equilibrium studies. Direct anastamosis of the ascending aorta and main pulmonary artery is superior to using a prosthetic conduit from descending aorta to pulmonary artery for creation of a long term stable left to right shunt

    This study investigates the rolling and drag resistance parameters and bicycle and cargo masses of typical urban cyclists. These factors are important for modelling of cyclist speed, power and energy expenditure, with applications including exercise performance, health and safety assessments and transportation network analysis. However, representative values for diverse urban travellers have not been established. Resistance parameters were measured utilizing a field coast-down test for 557 intercepted cyclists in Vancouver, Canada. Masses were also measured, along with other bicycle attributes such as tire pressure and size. The average (standard deviation) of coefficient of rolling resistance, effective frontal area, bicycle plus cargo mass, and bicycle-only mass were 0.0077 (0.0036), 0.559 (0.170) m 2 , 18.3 (4.1) kg, and 13.7 (3.3) kg, respectively. The range of measured values is wider and higher than suggested in existing literature, which focusses on sport cyclists. Significant correlations are identified between resistance parameters and rider and bicycle attributes, indicating higher resistance parameters for less sport-oriented cyclists. The findings of this study are important for appropriately characterising the full range of urban cyclists, including commuters and casual riders.

    Balance training is an effective intervention to improve static postural sway and balance. The purpose of the present study was to investigate the effectiveness of the Nintendo Wii Fit Plus exercises for improving balance ability in healthy collegiate students in comparison with a typical balance training program. Forty students were randomly divided into two groups, a traditional (T group) and a Nintendo Wii group (W group) performed an 8 week balance program. The "W group" used the interactive games as a training method, while the "T group" used an exercise program with mini trampoline and inflatable discs (BOSU). Pre and Post-training participants completed balance assessments. Two-way repeated measures analyses of variance (ANOVAs) were conducted to determine the effect of training program. Analysis of the data illustrated that both training program groups demonstrated an improvement in Total, Anterior-posterior and Medial Lateral Stability Index scores for both limbs. Only at the test performed in the balance board with anterior-posterior motion, the improvement in balance ability was greater in the "T group" than the "W group", when the assessment was performed post-training (p=0.023). Findings support the effectiveness of using the Nintendo Wii gaming console as a balance training intervention tool.

    Atypical/malignant meningiomas recur more frequently then typical meningiomas. In this study, the contribution of diffusion-weighted MR imaging to the differentiation of atypical/malignant and typical meningiomas and to the determination of histological subtypes of typical meningiomas was investigated. The study was performed prospectively on 39 patients. The signal intensity of the lesions was evaluated on trace and apparent diffusion coefficient (ADC) images. ADC values were measured in the lesions and peritumoral edema. Student's t-test was used for statistical analysis. P<0.05 was considered statistically significant. Mean ADC values in atypical/malignant and typical meningiomas were 0.75{+-}0.21 and 1.17{+-}0.21, respectively. Mean ADC values for subtypes of typical meningiomas were as follows: meningothelial, 1.09{+-}0.20; transitional, 1.19{+-}0.07; fibroblastic, 1.29{+-}0.28; and angiomatous, 1.48{+-}0.10. Normal white matter was 0.91{+-}0.10. ADC values of typical meningiomas and atypical/malignant meningiomas significantly differed (P<0.001). However, the difference between peritumoral edema ADC values was not significant (P>0.05). Furthermore, the difference between the subtypes of typical meningiomas and atypical/malignant meningiomas was significant (P<0.001). Diffusion-weighted MR imaging findings of atypical/malignant meningiomas and typical meningiomas differ. Atypical/malignant meningiomas have lower intratumoral ADC values than typical meningiomas. Mean ADC values for peritumoral edema do not differ between typical and atypical meningiomas. (orig.)

    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·cm 2 and even values above 200 Gy·cm 2 , 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·cm 2 and for PCI from 73 to 113 Gy·cm 2 , 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)

    There have been epidemiological studies of adverse events (AEs) among general patients but those of patients cared by cardiologist are not well scrutinized. We investigated the occurrence of AEs and medical errors (MEs) among adult patients with cardiology in Japan. We conducted a cross-sectional study of adult outpatients at a Japanese teaching hospital from February through November 2006. We measured AE and ME incidents from patient report, which were verified by medical records, laboratory data, incident reports, and prescription queries. Two independent physicians reviewed the incidents to determine whether they were AEs or MEs and to assess severity and symptoms. We identified 144 AEs and 30 MEs (16.3 and 3.9 per 100 patients, respectively). Of the 144 AEs, 99 were solely adverse drug events (ADEs), 20 were solely non-ADEs, and the remaining 25 were both causes. The most frequent symptoms of ADEs were skin and allergic reactions due to medication. The most frequent symptoms of non-ADEs were bleeding due to therapeutic interventions. Among AEs, 12% was life threatening. Life-threatening AEs were 25% of non-ADEs and 5% of ADEs (P = 0.0003). Among the 30 MEs, 21MEs (70%) were associated with drugs. Adverse events were common among cardiology patients. Adverse drug events were the most frequent AEs, and non-ADEs were more critical than ADEs. Such data should be recognized among practicing physicians to improve the patients' outcomes.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

    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 mGycm 2 ). 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 (MSD 1 = 3.0 Gy and MSD 2 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)

    Full Text Available OBJECTIVE: To report a training program in cardiology emphasizing changes in its pedagogical practice. These changes were put into practice by some teachers at the Medical School of Porto Alegre of the University of Rio Grande do Sul (FAMED/UFRGS aiming to make faculty and student activities more dynamic and to promote more efficacious learning. The training program is directed at 5th semester medical students and aims at a behavioral change in teachers and students to promote more interaction, to favor exchanges, and to make the teaching-learning process easier, always maintaining the patient in the center of the medical activity. METHODS: The program emphasizes the definition of general and specific objectives for each activity to be developed by the students, with training in the area of admission to the cardiology service, with special emphasis on behavioral change in the cognitive, motor, affective, and attitudinal areas. Knowledge was developed by means of interactive seminars with initial and final assessment tests to identify students' and teachers' performance. The students were evaluated in an immediate, continuous, and progressive way in their daily activities and through comparison of the results of 2 tests, one applied at the beginning of the training and the other at its end. These 2 tests contained the same questions. RESULTS: We systematically assessed 560 students over 4 years. The mean grades of the tests performed prior to and after the 244 seminars were 7.38±1.66 and 9.17± 0.82, respectively (p<0.0001. For the tests applied at the beginning and at the end of the training, the mean grades were 5.61±1.61 and 9.37±0.90, respectively (p<0.0001. CONCLUSION: The program proved to be efficient both for the students' learning and for assessing their performance in a systematic and objective way.

    Expert knowledge of cardiac malformations is essential for paediatric cardiologists. Current cardiac morphology fellowship teaching format, content, and nomenclature are left up to the discretion of the individual fellowship programmes. We aimed to assess practices and barriers in morphology education, perceived effectiveness of current curricula, and preferences for a standardised fellow morphology curriculum. A web-based survey was developed de novo and administered anonymously via e-mail to all paediatric cardiology fellowship programme directors and associate directors in the United States of America; leaders were asked to forward the survey to fellows. A total of 35 directors from 32 programmes (51%) and 66 fellows responded. Curriculum formats varied: 28 (88%) programmes utilised pathological specimens, 25 (78%) invited outside faculty, and 16 (50%) utilised external conferences. Director nomenclature preferences were split - 6 (19%) Andersonian, 8 (25%) Van Praaghian, and 18 (56%) mixed. Barriers to morphology education included time and inconsistent nomenclature. One-third of directors reported that <90% of recent fellow graduates had adequate abilities to apply segmental anatomy, identify associated cardiac lesions, or communicate complex CHD. More structured teaching, protected time, and specimens were suggestions to improve curricula. Almost 75% would likely adopt/utilise an online morphology curriculum. Cardiac morphology training varies in content and format among fellowships. Inconsistent nomenclature exists, and inadequate morphology knowledge is perceived to contribute to communication failures, both have potential patient safety implications. There is an educational need for a common, online cardiac morphology curriculum that could allow for fellow assessment of competency and contribute to more standardised communication in the field of paediatric cardiology.

    Neoplasms of the heart are rare. Usually asymptomatic on the early stage are diagnosed incidentally. Among primary heart neoplasms the most often benign tumors are diagnosed--mostly myxomas, whereas the majority of malignant heart tumors are sarcomas. The aim of this paper was to present heart tumors diagnosed in the cardiology department, their symptoms, used diagnostic tests and therapy and to show after therapy quality of life changes. There were 18 patients included to the study, whom during hospitalization in the cardiology department heart tumors were diagnosed. There were 11 women and 7 men, aged from 33- to 76-years-old (mean 60,5 years). To all of the patients medical interview, physical examination, EKG, UCG and laboratory test were performed. Additionally in some cases computed tomography or magnetic resonance imaging of the chest and coronary angiograms were done. Based on the diagnostic tests results the patients were qualified to conservative or surgical treatment. Among 18 heart tumor patients in 12 cases primary benign tumors were diagnosed (66,6%), 1 patient had primary malignant tumor (5,5%), there were 3 cases of metastatic tumors (16,6%) and 2 patients with non-neoplasmic tumors--clots (11,1%). From 18 subjects with heart tumor 3 patients died because of advanced stage of neoplasmic disease and presence of metastatic tumors in the heart. Results of the study show, that heart tumors, regardless of development of diagnostic tests, are still diagnosed too late. The study group follow-up proved, that early diagnosis and proper heart tumor treatment prevented complications and improved the quality of life. It is worth to emphasize, that coronary angiogram in some cases allowed to diagnose coronary artery disease, to treat heart tumor and to perform coronary artery by-pass grafting simultaneously.

    Full Text Available OBJECTIVE: To analyze the early and late results of cardiopulmonary resuscitation in a cardiology hospital and to try to detect prognostic determinants of both short- and long-term survival. METHODS: A series of 557 patients who suffered cardiorespiratory arrest (CRA at the Dante Pazzanese Cardiology Institute over a period of 5 years was analyzed to examine factors predicting successful resuscitation and long-term survival. RESULTS: Ressuscitation maneuvers were tried in 536 patients; 281 patients (52.4% died immediately, and 164 patients (30.6% survived for than 24 hours. The 87 patients who survived for more than 1 month after CRA were compared with nonsurvivors. Coronary disease, cardiomyopathy, and valvular disease had a better prognosis. Primary arrhythmia occurred in 73.5% of the >1-month survivor group and heart failure occurred in 12.6% of this group. In those patients in whom the initial mechanism of CRA was ventricular fibrillation, 33.3% survived for more than 1 month, but of those with ventricular asystole only 4.3% survived. None of the 10 patients with electromechanical dissociation survived. There was worse prognosis in patients included in the extreme age groups (zero to 10 years and 70 years or more. The best results occurred when the cardiac arrest took place in the catheterization laboratories. The worst results occurred in the intensive care unit and the hemodialysis room. CONCLUSION: The results in our series may serve as a helpful guide to physicians with the difficult task of deciding when not to resuscitate or when to stop resuscitation efforts.

    Full Text Available The literature review presents an analysis of publications describing the use of a glucose%insulin mixture as a cardioprotective agent in acute myocardial infarction and in cardiac surgeries with extracorporeal circulation (ECC. It summarizes historical aspects of implementation of the glucose%insulin therapy in cardiology and car%diac surgery. Possible mechanisms of action of the glucose-insulin-potassium mixture in acute ischemia and myocardial infarction were analyzed (normalization of electrical processes on the cardiomyocyte membrane, replenishment of metabolic substrates and increased production rate of adenosine triphosphoric acid due to glycolysis, decreased intensity of non%esterified fatty acid oxidation, decreased apoptosis, etc.. It discusses results of clinical studies evaluating prescription of the mixture for acute myocardial infarction, including data from metaanalyses. It demonstrated that the role and the clinical efficacy of the preventive and therapeutic measure under consideration in acute myocardial infarction are still the subject of discussion and require further research. It also analyzed modern concepts explaining the cardioprotective effects of insulin and glucose during surgeries with ECC (decreased insulin resistance, activation of anaplerosis, stimulation of intracellular signaling pathways maintaining the viability of cells, reduction of the severity of systemic inflammatory response, immunomodulatingeffect, etc.. Review discusses results of clinical studies including data from randomized clinical trials and metaanalyses performed over the last 5 years that demonstrated the absence of the effect of the glucose%insulin therapy on the hospital mortality. Various studies demonstrated its positive effects including decreased incidence of peri%operative myocardial infarctions and intensity of inotropic support, increased values of postoperative cardiac index, decreased duration of postoperative mechanical ventilation

    Thousands of physicians attend scientific meetings annually. Although hospital physician staffing and composition may be affected by meetings, patient outcomes and treatment patterns during meeting dates are unknown. To analyze mortality and treatment differences among patients admitted with acute cardiovascular conditions during dates of national cardiology meetings compared with nonmeeting dates. Retrospective analysis of 30-day mortality among Medicare beneficiaries hospitalized with acute myocardial infarction (AMI), heart failure, or cardiac arrest from 2002 through 2011 during dates of 2 national cardiology meetings compared with identical nonmeeting days in the 3 weeks before and after conferences (AMI, 8570 hospitalizations during 82 meeting days and 57,471 during 492 nonmeeting days; heart failure, 19,282 during meeting days and 11,4591 during nonmeeting days; cardiac arrest, 1564 during meeting days and 9580 during nonmeeting days). Multivariable analyses were conducted separately for major teaching hospitals and nonteaching hospitals and for low- and high-risk patients. Differences in treatment utilization were assessed. Hospitalization during cardiology meeting dates. Thirty-day mortality, procedure rates, charges, length of stay. Patient characteristics were similar between meeting and nonmeeting dates. In teaching hospitals, adjusted 30-day mortality was lower among high-risk patients with heart failure or cardiac arrest admitted during meeting vs nonmeeting dates (heart failure, 17.5% [95% CI, 13.7%-21.2%] vs 24.8% [95% CI, 22.9%-26.6%]; P cardiology meetings. High-risk patients with heart failure and cardiac arrest hospitalized in teaching hospitals had lower 30-day mortality when admitted during dates of national cardiology meetings. High-risk patients with AMI admitted to teaching hospitals during meetings were less likely to receive PCI, without any mortality effect.

    The post-cardiac arrest (CA) period is often associated with secondary damage of the brain that leads to severe neurological deficits. The current practice guidelines recommend the use of therapeutic hypothermia (TH) to prevent neurological deficit and improve survival. The aim of the study was to investigate the implementation of medical guidelines in clinical practice and to evaluate the barriers for implementation of TH in cardiology units in Poland. A telephone survey, fax and online inquiry form were used to assess the implementation of TH in cardiology units in the management of unconscious patients after cardiac arrest (CA). The questions addressed the local practice, TH protocol, reasons for not using TH and outcomes of CA patients. We obtained information from 79 units out of 150 asked (53%). At the time of the survey, 24 units (30.8%) were using TH as part of their post-CA management. Of all CA patients, 45% underwent TH in cardiac intensive care units (CICU), 37.5% in the coronary care unit (CCU) and 12.5% in the intensive care unit (ICU). The major barrier for the implementation of TH declared by the non-cooling centers was lack of sufficient knowledge regarding the technique and protocol, as well as experience (37%); access to dedicated equipment was not perceived as an obstacle. The number of cardiology units that provide TH for comatose CA patients is low. The main limiting factor for wider use of TH is lack of knowledge and experience. There is a clear need for urgent educational activities for cardiology units. The benefits of TH still have not reached their potential in cardiology units.

  16. The importance of being 'well-placed': the influence of context on perceived typicality and esthetic appraisal of product appearance.

    Earlier findings have suggested that esthetic appraisal of product appearances is influenced by perceived typicality. However, prior empirical research on typicality and esthetic appraisal of product appearances has not explicitly taken context effects into account. In this paper, we investigate how a specific context influences perceived typicality and thus the esthetic appraisal of product appearances by manipulating the degree of typicality of a product's appearance and its context. The findings of two studies demonstrate that the perceived typicality of a product appearance and consequently its esthetic appraisal vary depending on the typicality of the context in which the product is presented. Specifically, contrast effects occur for product appearances that are perceived as typical. Typical product appearances are perceived as more typical and are more esthetically appealing when presented in an atypical context compared to when presented in a typical context. No differences in perceived typicality and esthetic appraisal were found for product appearances that are perceived as atypical. Copyright © 2011 Elsevier B.V. All rights reserved.

    Aims To characterize patient radiation doses from nuclear myocardial perfusion imaging (MPI) and the use of radiation-optimizing ‘best practices’ worldwide, and to evaluate the relationship between laboratory use of best practices and patient radiation dose. Methods and results We conducted an observational cross-sectional study of protocols used for all 7911 MPI studies performed in 308 nuclear cardiology laboratories in 65 countries for a single week in March–April 2013. Eight ‘best practices’ relating to radiation exposure were identified a priori by an expert committee, and a radiation-related quality index (QI) devised indicating the number of best practices used by a laboratory. Patient radiation effective dose (ED) ranged between 0.8 and 35.6 mSv (median 10.0 mSv). Average laboratory ED ranged from 2.2 to 24.4 mSv (median 10.4 mSv); only 91 (30%) laboratories achieved the median ED ≤ 9 mSv recommended by guidelines. Laboratory QIs ranged from 2 to 8 (median 5). Both ED and QI differed significantly between laboratories, countries, and world regions. The lowest median ED (8.0 mSv), in Europe, coincided with high best-practice adherence (mean laboratory QI 6.2). The highest doses (median 12.1 mSv) and low QI (4.9) occurred in Latin America. In hierarchical regression modelling, patients undergoing MPI at laboratories following more ‘best practices’ had lower EDs. Conclusion Marked worldwide variation exists in radiation safety practices pertaining to MPI, with targeted EDs currently achieved in a minority of laboratories. The significant relationship between best-practice implementation and lower doses indicates numerous opportunities to reduce radiation exposure from MPI globally. PMID:25898845

    Full Text Available Ensemble perception, the ability to assess automatically the summary of large amounts of information presented in visual scenes, is available early in typical development. This ability might be compromised in autistic children, who are thought to present limitations in maintaining summary statistics representations for the recent history of sensory input. Here we examined ensemble perception of facial emotional expressions in 35 autistic children, 30 age- and ability-matched typical children and 25 typical adults. Participants received three tasks: a an ‘ensemble’ emotion discrimination task; b a baseline (single-face emotion discrimination task; and c a facial expression identification task. Children performed worse than adults on all three tasks. Unexpectedly, autistic and typical children were, on average, indistinguishable in their precision and accuracy on all three tasks. Computational modelling suggested that, on average, autistic and typical children used ensemble-encoding strategies to a similar extent; but ensemble perception was related to non-verbal reasoning abilities in autistic but not in typical children. Eye-movement data also showed no group differences in the way children attended to the stimuli. Our combined findings suggest that the abilities of autistic and typical children for ensemble perception of emotions are comparable on average.

    Youth who feel they do not fit with gender norms frequently experience peer victimization and socioemotional distress. To gauge differences between schools, the current study examined the longitudinal effects of school-level gender norm salience-a within-school association between gender typicality and peer victimization-on socioemotional distress across 26 ethnically diverse middle schools (n boys  = 2607; n girls  = 2805). Boys (but not girls) reporting lower gender typicality experienced more loneliness and social anxiety in schools with more salient gender norms, even when accounting for both individual and school level victimization. Greater gender norm salience also predicted increased depressed mood among boys regardless of gender typicality. These findings suggest particular sensitivity among boys to environments in which low gender typicality is sanctioned.

    The natural history of brain growth in autism spectrum disorders remains unclear. Cross-sectional studies have identified regional abnormalities in brain volume and cortical thickness in autism, although substantial discrepancies have been reported. Preliminary longitudinal studies using two time points and small samples have identified specific regional differences in cortical thickness in the disorder. To clarify age-related trajectories of cortical development, we examined longitudinal changes in cortical thickness within a large mixed cross-sectional and longitudinal sample of autistic subjects and age- and gender-matched typically developing controls. Three hundred and forty-five magnetic resonance imaging scans were examined from 97 males with autism (mean age = 16.8 years; range 3-36 years) and 60 males with typical development (mean age = 18 years; range 4-39 years), with an average interscan interval of 2.6 years. FreeSurfer image analysis software was used to parcellate the cortex into 34 regions of interest per hemisphere and to calculate mean cortical thickness for each region. Longitudinal linear mixed effects models were used to further characterize these findings and identify regions with between-group differences in longitudinal age-related trajectories. Using mean age at time of first scan as a reference (15 years), differences were observed in bilateral inferior frontal gyrus, pars opercularis and pars triangularis, right caudal middle frontal and left rostral middle frontal regions, and left frontal pole. However, group differences in cortical thickness varied by developmental stage, and were influenced by IQ. Differences in age-related trajectories emerged in bilateral parietal and occipital regions (postcentral gyrus, cuneus, lingual gyrus, pericalcarine cortex), left frontal regions (pars opercularis, rostral middle frontal and frontal pole), left supramarginal gyrus, and right transverse temporal gyrus, superior parietal lobule, and

  2. Stored object knowledge and the production of referring expressions: The case of color typicality

    Directory of Open Access Journals (Sweden)

    Hans eWesterbeek

    2015-07-01

    Full Text Available When speakers describe objects with atypical properties, do they include these properties in their referring expressions, even when that is not strictly required for unique referent identification? Based on previous work, we predict that speakers mention the color of a target object more often when the object is atypically colored, compared to when it is typical. Taking literature from object recognition and visual attention into account, we further hypothesize that this behavior is proportional to the degree to which a color is atypical, and whether color is a highly diagnostic feature in the referred-to object's identity. We investigate these expectations in two language production experiments, in which participants referred to target objects in visual contexts. In Experiment 1, we find a strong effect of color typicality: less typical colors for target objects predict higher proportions of referring expressions that include color. In Experiment 2 we manipulated objects with more complex shapes, for which color is less diagnostic, and we find that the color typicality effect is moderated by color diagnosticity: it is strongest for high-color-diagnostic objects (i.e., objects with a simple shape. These results suggest that the production of atypical color attributes results from a contrast with stored knowledge, an effect which is stronger when color is more central to object identification. Our findings offer evidence for models of reference production that incorporate general object knowledge, in order to be able to capture these effects of typicality on determining the content of referring expressions.

    Surgery after pre-operative embolization has become the main treatment modality in angiofibroma therapy. As surgical planning is based on precise pre-operative tumour evaluation, knowledge of the characteristic growth patterns is of great interest. Analysis of tumour extension and blood supply, as well as methods of controlling intra-operative bleeding, help in determining the appropriate surgical approach. Though benign, angiofibroma demonstrates a locally aggressive nature. This fibrovascular tumour is characterised by typical radiological findings and by predictable growth patterns. The tumour extension and blood supply can be accurately determined by CT, MR imaging and angiography. With classic radiological findings, no pre-operative biopsy is necessary in most angiofibromas. Advances in radiological imaging have contributed to improved surgical planning and tumour resection. The surgeon is able to select the least traumatic approach with secure haemostatic control, which is also critical for avoiding the disturbance of facial skeletal growth in this group of young patients. Embolization, pre-operative autologous donation and the cell saver system for immediate retransfusion of the collected blood after filtration, are important tools for dealing with blood loss in angiofibroma surgery as they minimize homologous blood transfusion.

  4. Concept typicality responses in the semantic memory network.

    2016-12-01

    For decades concept typicality has been recognized as critical to structuring conceptual knowledge, but only recently has typicality been applied in better understanding the processes engaged by the neurological network underlying semantic memory. This previous work has focused on one region within the network - the Anterior Temporal Lobe (ATL). The ATL responds negatively to concept typicality (i.e., the more atypical the item, the greater the activation in the ATL). To better understand the role of typicality in the entire network, we ran an fMRI study using a category verification task in which concept typicality was manipulated parametrically. We argue that typicality is relevant to both amodal feature integration centers as well as category-specific regions. Both the Inferior Frontal Gyrus (IFG) and ATL demonstrated a negative correlation with typicality, whereas inferior parietal regions showed positive effects. We interpret this in light of functional theories of these regions. Interactions between category and typicality were not observed in regions classically recognized as category-specific, thus, providing an argument against category specific regions, at least with fMRI.

    The present paper aims at developping a method to reasonably set up the typical spectral color dataset for different kinds of Chinese cultural heritage in color rendering process. The world famous wall paintings dating from more than 1700 years ago in Dunhuang Mogao Grottoes was taken as typical case in this research. In order to maintain the color constancy during the color rendering workflow of Dunhuang culture relics, a chromatic adaptation based method for developping the spectral dataset of typical colors for those wall paintings was proposed from the view point of human vision perception ability. Under the help and guidance of researchers in the art-research institution and protection-research institution of Dunhuang Academy and according to the existing research achievement of Dunhuang Research in the past years, 48 typical known Dunhuang pigments were chosen and 240 representative color samples were made with reflective spectral ranging from 360 to 750 nm was acquired by a spectrometer. In order to find the typical colors of the above mentioned color samples, the original dataset was devided into several subgroups by clustering analysis. The grouping number, together with the most typical samples for each subgroup which made up the firstly built typical color dataset, was determined by wilcoxon signed rank test according to the color inconstancy index comprehensively calculated under 6 typical illuminating conditions. Considering the completeness of gamut of Dunhuang wall paintings, 8 complementary colors was determined and finally the typical spectral color dataset was built up which contains 100 representative spectral colors. The analytical calculating results show that the median color inconstancy index of the built dataset in 99% confidence level by wilcoxon signed rank test was 3.28 and the 100 colors are distributing in the whole gamut uniformly, which ensures that this dataset can provide reasonable reference for choosing the color with highest

    The availability of more sensitive biomarkers of myonecrosis and a new classification system from the universal definition of myocardial infarction (MI) have led to evolution of the classification of MI. The prognostic implications of MI defined in the current era have not been well described. We investigated the association between new or recurrent MI by subtype according to the European Society of Cardiology/American College of Cardiology/American Heart Association/World Health Federation Task Force for the Redefinition of MI Classification System and the risk of cardiovascular death among 13 608 patients with acute coronary syndrome in the Trial to Assess Improvement in Therapeutic Outcomes by Optimizing Platelet Inhibition with Prasugrel-Thrombolysis in Myocardial Infarction 38 (TRITON-TIMI 38). The adjusted risk of cardiovascular death was evaluated by landmark analysis starting at the time of the MI through 180 days after the event. Patients who experienced an MI during follow-up had a higher risk of cardiovascular death at 6 months than patients without an MI (6.5% versus 1.3%, P<0.001). This higher risk was present across all subtypes of MI, including type 4a (peri-percutaneous coronary intervention, 3.2%; P<0.001) and type 4b (stent thrombosis, 15.4%; P<0.001). After adjustment for important clinical covariates, the occurrence of any MI was associated with a 5-fold higher risk of death at 6 months (95% confidence interval 3.8-7.1), with similarly increased risk across subtypes. MI is associated with a significantly increased risk of cardiovascular death, with a consistent relationship across all types as defined by the universal classification system. These findings underscore the clinical relevance of these events and the importance of therapies aimed at preventing MI.

    Accurate prediction of building energy performance requires precise information of the local climate. Typical weather year files like typical meteorological year (TMY) are commonly used in building simulation. They are also essential for numerical analysis of sustainable and renewable energy systems. The present paper presents the generation of typical meteorological year (TMY) for eight typical cities representing the major climate zones of China. The data set, which includes global solar radiation data and other meteorological parameters referring to dry bulb temperature, relative humidity, wind speed, has been analyzed. The typical meteorological year is generated from the available meteorological data recorded during the period 1995-2004, using the Finkelstein-Schafer statistical method. The cumulative distribution function (CDF) for each year is compared with the CDF for the long-term composite of all the years in the period. Typical months for each of the 12 calendar months from the period of years are selected by choosing the one with the smallest deviation from the long-term CDF. The 12 typical months selected from the different years are used for the formulation of a TMY.

    Despite the growing number of therapeutic alternatives available as well as general reviews and treatment guidelines for the treatment of diabetes, physicians are often left without a clear pathway of therapy to follow in specific clinical contexts such as interventional cardiology. The present document proposes a consensus treatment algorithm, based both on a critical appraisal of evidence from recent clinical trials and on value judgements supported by the authors' collective clinical knowledge and experience, in an attempt to guide practitioners when choosing the most appropriate alternatives in the context of glycemic management in type 1 and 2 diabetic patients scheduled to undergo interventional cardiology procedures in a haemodynamic laboratory.

    Radiofrequency ablation (RFA) is the treatment of choice of cavotricuspid isthmus (CTI)-dependent atrial flutter. Procedural time is highly variable due to anatomical structures. This study aimed to characterize CTI anatomy by transesophageal 3D echocardiography imaging (3D-TEE) to identify anatomic structures related to longer ablation time. Thirty-one consecutive patients (mean age 67.3 ± 11.5 years, 22 males) underwent CTI-ablation procedure. Before ablation, TEE was performed and 3D-TEE images were acquired to evaluate CTI anatomy qualitatively as well as perform measures of CTI morphological features. The electrophysiologist performing RFA was blinded to 3D-TEE data. Bidirectional block of CTI was achieved in all patients without procedural complications after a median ablation time of 11 (IQR 7-14) min. Patients with RFA time ≥11 min (Group 2) presented lower left ventricular ejection fraction (51.1 ± 17.0 vs. 59.5 ± 6.6%, P 3D-TEE imaging is extremely helpful in qualitative and quantitative evaluation of CTI anatomy in patients undergoing RFA for symptomatic typical atrial flutter. Detection of a deep right atrial pouch was found to be associated with significantly prolonged CTI ablation time to achieve bidirectional block.

    Gender differences in autobiographical memory emerge in some data collection paradigms and not others. The present study included an extensive analysis of gender differences in autobiographical narratives. Data were collected from 196 participants, evenly split by gender and by age group (emerging adults, ages 18-29, and young adults, ages 30-40). Each participant reported four narratives, including an event that had occurred in the last 2 years, a high point, a low point, and a self-defining memory. Additionally, all participants completed self-report measures of masculine and feminine gender typicality. The narratives were coded along six dimensions-namely coherence, connectedness, agency, affect, factual elaboration, and interpretive elaboration. The results indicated that females expressed more affect, connection, and factual elaboration than males across all narratives, and that feminine typicality predicted increased connectedness in narratives. Masculine typicality predicted higher agency, lower connectedness, and lower affect, but only for some narratives and not others. These findings support an approach that views autobiographical reminiscing as a feminine-typed activity and that identifies gender differences as being linked to categorical gender, but also to one's feminine gender typicality, whereas the influences of masculine gender typicality were more context-dependent. We suggest that implicit gendered socialization and more explicit gender typicality each contribute to gendered autobiographies.

    Full Text Available Abstract Background There is an ongoing debate over whether atypical antipsychotics are more effective than typical antipsychotics in the treatment of schizophrenia. This naturalistic study compares atypical and typical antipsychotics on time to all-cause medication discontinuation, a recognized index of medication effectiveness in the treatment of schizophrenia. Methods We used data from a large, 3-year, observational, non-randomized, multisite study of schizophrenia, conducted in the U.S. between 7/1997 and 9/2003. Patients who were initiated on oral atypical antipsychotics (clozapine, olanzapine, risperidone, quetiapine, or ziprasidone or oral typical antipsychotics (low, medium, or high potency were compared on time to all-cause medication discontinuation for 1 year following initiation. Treatment group comparisons were based on treatment episodes using 3 statistical approaches (Kaplan-Meier survival analysis, Cox Proportional Hazards regression model, and propensity score-adjusted bootstrap resampling methods. To further assess the robustness of the findings, sensitivity analyses were performed, including the use of (a only 1 medication episode for each patient, the one with which the patient was treated first, and (b all medication episodes, including those simultaneously initiated on more than 1 antipsychotic. Results Mean time to all-cause medication discontinuation was longer on atypical (N = 1132, 256.3 days compared to typical antipsychotics (N = 534, 197.2 days; p Conclusion In the usual care of schizophrenia patients, time to medication discontinuation for any cause appears significantly longer for atypical than typical antipsychotics regardless of the typical antipsychotic potency level. Findings were primarily driven by clozapine and olanzapine, and to a lesser extent by risperidone. Furthermore, only clozapine and olanzapine therapy showed consistently and significantly longer treatment duration compared to perphenazine, a medium

    Full text: As part of the International Action Plan for Protection of Patients and supporting by the IAEA, a survey on patient doses in fluoroscopy guided procedures in cardiology in Latin America has been conducted since 2006. One of the objectives of the survey was to set criteria for the identification and evaluation of high skin doses in a certain number of patients to recommend a clinical follow up for potential radiation injuries (more than 3 Gy at the skin). The used methodology for the survey was initiated with two dedicated workshops held in Santiago de Chile (2005) and San Jose de Costa Rica (2007) involving relevant cardiologists from 15 different Latin American Countries. Some sessions were also attended by experts from the Regulatory and Health Authorities. Standardized forms to collect demographic and patient dosimetric data were agreed. Considering that most of the involved centres had still not dosimeters installed in the cardiology x-ray systems, it was agreed to collect data on fluoroscopy time and total number of cine frames per procedure. Relevant factors influencing radio sensitivity of the skin were also collected. Data from 10 countries representing a sample of 709 patients were received during the first year. Procedures included were diagnostic (DG) (coronary angiography and electrophysiology studies), therapeutic (TH) (percutaneous transluminal coronary angioplasties, cardiac ablations and valvuloplasties) or including both DG and TH. A total of 26 patients (3.7%) were selected for potential high skin doses. Initial considered criteria for selection were more than 30 minutes of fluoroscopy, more than 3,000 cine frames per procedure or patients with more than 100 kg of weight. Maximum reported values were 72 minutes and 8,100 frames. In addition, 5 of these patients were diabetic, 6 have previous fluoroscopy procedures and 5 were over 95 kg. The percentage of selected cases for clinical follow up derived from potential skin injuries seem

There are no controlled, prospective studies of scribe use in the clinic setting. Methods: A prospective controlled study compared standard visits (20 minute follow-up and 40 minute new patient to a scribe system (15 minute follow-up and 30 minute new patient in a cardiology clinic. Physician productivity, patient satisfaction, physician–patient interaction, and revenue were measured. Results: Four physicians saw 129 patients using standard care and 210 patients with scribes during 65 clinic hours each. Patients seen per hour increased (P < 0.001 from 2.2 ± 0.3 to 3.5 ± 0.4 (59% increase and work relative value units (wRVU per hour increased (P < 0.001 from 3.5 ± 1.3 to 5.5 ± 1.3 (57% increase. Patient satisfaction was high at baseline and unchanged with scribes. In a substudy, direct patient contact time was lower (9.1 ± 2.0 versus 12.9 ± 3.4 minutes; P < 0.01 for scribe visits, but time of patient interaction (without computer was greater (6.7 ± 2.1 versus 1.5 ± 1.9 minutes; P < 0.01. Subjective assessment of physician–patient interaction (1–10 was higher (P < 0.01 on scribe visits (9.1 ± 0.9 versus 7.9 ± 1.1. Direct and indirect (downstream revenue per patient seen was $142 and $2,398, with $205,740 additional revenue generated from the 81 additional patients seen with scribes. Conclusion: Using scribes in a cardiology clinic is feasible, produces improvements in physician–patient interaction, and results in large increases in physician productivity and system cardiovascular revenue.
