Ruling out coronary heart disease in primary care patients with chest pain : a clinical prediction score

ABSTRACT: BACKGROUND: Chest pain raises concern for the possibility of coronary heart disease. Scoring methods have been developed to identify coronary heart disease in emergency settings, but not in primary care. METHODS: Data were collected from a multicenter Swiss clinical cohort study including 672 consecutive patients with chest pain, who had visited one of 59 family practitioners' offices. Using delayed diagnosis we derived a prediction rule to rule out coronary heart disease by means of a logistic regression model. Known cardiovascular risk factors, pain characteristics, and physical signs associated with coronary heart disease were explored to develop a clinical score. Patients diagnosed with angina or acute myocardial infarction within the year following their initial visit comprised the coronary heart disease group. RESULTS: The coronary heart disease score was derived from eight variables: age, gender, duration of chest pain from 1 to 60 minutes, substernal chest pain location, pain increases with exertion, absence of tenderness point at palpation, cardiovascular risks factors, and personal history of cardiovascular disease. Area under the receiver operating characteristics curve was of 0.95 with a 95% confidence interval of 0.92; 0.97. From this score, 413 patients were considered as low risk for values of percentile 5 of the coronary heart disease patients. Internal validity was confirmed by bootstrapping. External validation using data from a German cohort (Marburg, n = 774) revealed a receiver operating characteristics curve of 0.75 (95% confidence interval, 0.72; 0.81) with a sensitivity of 85.6% and a specificity of 47.2%. CONCLUSIONS: This score, based only on history and physical examination, is a complementary tool for ruling out coronary heart disease in primary care patients complaining of chest pain.

What Kind of Justice Today ? Expectations Of 'Good Justice', Convergences And Divergences Between Managerial And Judicial Actors And How They Fit Within Management-Oriented Values

This research aims toward a better understanding of the organizational culture(s) of the judiciary in Switzerland by analysing what 'good justice' means nowadays in this country. It seeks to clarify whether, and to what extent, expectations of 'good justice' of judicial actors (judges without managerial experience) and of managerial actors (court managers) are similar and to describe possible managerial implications that may result from this. As judges are at the heart of the judicial organization and exert a strong influence on other groups of actors (Sullivan, Warren et al. 1994), the congruence of their expectations with those of court managers will be at the centre of the analysis. Additionally, referring to the conceptual worlds of Boltanski and Thévenaut (1991), we analyze how closely these expectations are to management-oriented values. We found that almost half of expectations are common to the two groups examined and the main quoted ones are compatible to new public management (NPM) concepts. On the other hand, those expectations shared exclusively by judges relate to the human side of justice, whereas those specific to court managers focus on the way justice functions.

Changes in antihypertensive drug treatment in the general population: the Colaus Study

Background and aims: there is little information regar ding changes in antihypertensive drug treatment in Switzerland. We aimed at assessing those changes in a population-based, prospective study. Methods: 768 hypertensive subjects (372 women, 397 men) followed for 5 years. Subjects were defined as continuers (no change), switchers (one antihypertensive class replace by another), combiners (one antihypertensive class added) and discontinuers (stopped treatment). Results: Analysis of all patients (mono or combination therapy) showed that 54.6% were continuers, 27.2% combiners, 12.9% switchers and 5.3 % discontinuers. Similar findings were obtained for participants on monotherapy only: 42.2% continuers, 36.7% combiners, 13.4% switchers and 7.7% discontinuers. Combiners had higher systolic and diastolic blood pressure values at baseline than the other groups (p<0.001), while no difference were found for personal and family history and other clinical and biological variables. Compared to continuers, combiners and switchers improved their blood pressure status at follow-up: 26.7% of combiners and 26.3% of switchers improved, versus 17.7% of continuers and 7.3% of discontinuers (p<0.001). Among participants on monotherapy at baseline, continuation was greatest for angiotensin II type 1 receptor blocking agents (ARBs, 53.1%), angiotensin-converting enzyme inhibitors (44.4%) and β-blockers (41.8%). Only one quarter of participants treated with diuretic or calcium channel blockers at baseline remained so at follow-up. Conclusion: Antihypertensivedrug treatment is very stable in Switzerland. There are no big differences in persistence between antihypertensive classes, even if ARBs had the most favorable utilization pattern. Changes are only due to blood pressure level and improve blood pressure status.

Il pastore pentecostale : un filo conduttore tra il cielo e la terra

Cet article se propose de prendre pour objet deux assemblées pentecôtistes de l'Est de la France - l'Église Évangélique de Pentecôte de Besançon (Franche-Comté) et la Porte Ouverte Chrétienne de Mulhouse (Alsace) - qui ont fait l'objet d'investigations ethnographiques dans le cadre de notre thèse de doctorat. Après avoir situé ces deux assemblées dans la mouvance du pentecôtisme français, nous nous sommes concentré sur la figure du pasteur pentecôtiste. L'exemplarité de l'histoire de vie des pasteurs, le rôle central que jouent ces derniers dans la « mise en présence » du Saint Esprit durant le culte et l'inspiration divine dont sont supposés être imprégnés leurs enseignements bibliques légitiment ce personnage dans sa fonction d'intermédiaire incontournable dans la relation entre le fidèle et son Dieu, alors même que le pentecôtisme s'inscrit historiquement dans la mouvance évangélique qui valorise la relation personnelle du chrétien né de nouveau avec son créateur. This paper considers two Pentecostal assemblies in Eastern France - the Église Évangélique de Pentecôte of Besançon (Franche-Comté) and the Porte Ouverte Chrétienne of Mulhouse (Alsace) - I have investigated for my PhD research, following an ethnographical method. After located these two assemblies in the sphere of influence of the French Pentecostalism, we focused on the Pentecostal pastor figure. The exemplary nature of the story of life of the pastors, the central role that pastors play in encounters with divine during the cult and the divine inspiration of their biblical educations legitimize this figure like inescapable intermediary between the believer and his God. Even if Pentecostalism is historically part of the evangelical sphere of influence which values personal relationships of the born again Christian with his creator.

Ascending aorta measurements as assessed by ECG-gated multi-detector computed tomography : a pilot study to etablish normative values for transcatheters therapies

Rapport de synthèse : Mesures de l'aorte ascendante par scanner synchronisé au rythme cardiaque: une étude pilote pour établir des valeurs normatives dans le cadre des futures thérapies par transcathéter. Objectif : L'objectif de cette étude est d'établir les valeurs morphométriques normatives de l'aorte ascendante à l'aide de l'angiographie par scanner synchronisé au rythme cardiaque, afin d'aider au développement des futurs traitements par transcathéter. Matériels et méthodes : Chez soixante-dix-sept patients (âgé de 22 à 83 ans, âge moyen: 54,7 ans), une angiographie par scanner synchronisé au rythme cardiaque a été réalisée pour évaluation des vaisseaux coronaires. Les examens ont été revus afin d'étudier l'anatomie de la chambre de chasse du ventricule gauche jusqu'au tronc brachio-céphalique droit. A l'aide de programmes de reconstructions multiplanaires et de segmentation automatique, différents diamètres et longueurs considérés comme importants pour les futurs traitements par transcathéter ont été mesurés. Les valeurs sont exprimées en moyennes, médianes, maximums, minimums, écart-types et en coefficients de variation. Les variations de diamètre de l'aorte ascendante durant le cycle cardiaque ont été aussi considérées. Résultats : Le diamètre moyen de la chambre de chasse du ventricule gauche était de 20.3+/-3.4 mm. Au niveau du sinus coronaire de l'aorte, il était de 34.2+/-4.1 mm et au niveau de la jonction sinotubulaire il était de 29.7+/-3.4 mm. Le diamètre moyen de l'aorte ascendante était de 32.7+/-3.8 mm. Le coefficient de variation de ces mesures variait de 12 à 17%. La distance moyenne entre l'insertion proximale des valvules aortiques et le départ du tronc brachio-céphalique droit était de 92.6+/-11.8 mm. La distance moyenne entre l'insertion proximale des valvules aortiques et l'origine de l'artère coronaire proximale était de 12.1+/-3.7 mm avec un coefficient de variation de 31%. La distance moyenne entre les deux ostia coronaires était de 7.2+/-3.1 mm avec un coefficient de variation de 43%. La longueur moyenne du petit arc de l'aorte ascendante entre l'artère coronaire gauche et le tronc brachio-céphalique droit était de 52.9+/-9.5 mm. La longueur moyenne de la continuité fibreuse entre la valve aortique et la valvule mitrale antérieure était de 14.6+/-3.3 mm avec un coefficient de variation de 23%. L'aire moyenne de la valve aortique était de 582.0+/-131.9 mm2. La variation du diamètre antéro-postérieur et transverse de l'aorte ascendante était respectivement de 8.4% et de 7.3%. Conclusion Il existe d'importantes variations inter-individuelles dans les mesures de l'aorte ascendante avec cependant des variations intra-individuelles faibles durant le cycle cardiaque. De ce fait, une approche personnalisée pour chaque patient est recommandée dans la confection des futures endoprothèses de l'aorte ascendante. Le scanner synchronisé au rythme cardiaque jouera un rôle prépondérant dans le bilan préthérapeutique. Abstract : The aim of this study was to provide an insight into normative values of the ascending aorta in regards to novel endovascular procedures using ECG-gated multi-detector CT angiography. Seventy-seven adult patients without ascending aortic abnormalities were evaluated. Measurements at relevant levels of the aortic root and ascending aorta were obtained. Diameter variations of the ascending aorta during cardiac cycle were also considered. Mean diameters (mm) were as follows: LV outflow tract 20.3+/-3.4, coronary sinus 34.2+/-4.1, sinotubular junction 29.7+-3.4 and mid ascending aorta 32.7+/-3.8 with coefficients of variation (CV) ranging from 12 to 17%. Mean distances (mm) were: from the plane passing through the proximal insertions of the aortic valve cusps to the right brachio-cephalic artery (BCA) 92.6111.8, from the plane passing through the proximal insertions of the aortic valve cusps to the proximal coronary ostium 12.1+/-3.7, and between both coronary ostia 7.2+/-3.1, minimal arc of the ascending aorta from left coronary ostium to right BCA 52.9 X9.5, and the fibrous continuity between the aortic valve and the anterior leaflet of the mitral valve 14.óf3.3, CV 13-43%. Mean aortic valve area was 582+-131.9 mm2. The variations of the antero-posterior and transverse diameters of the ascending aorta during the cardiac cycle were 8.4% and 7.3%, respectively. Results showed large inter-individual variations in diameters and distances but with limited intra-individual variations during the cardiac cycle. A personalized approach for planning endovascular devices must be considered.

Militarism and Melodrama: The Cultural Work of Combat Death

This essay examines the role of melodrama in the American war film, focusing on three post-WWII examples. The main argument centers on the natural alliance between melodrama and militarism based on a shared intolerance for the notion of death as meaningless and in vain. Both melodrama and military ideology employ elaborate rhetorical and narrative strategies to enfold deaths into larger systems of meaning, such as the nation, or in more personal terms, as a rite of passage. One of the most common narrative devices present in the military melodrama is the death that converts survivors to the values of the virtuous victim. The essay examines the shared conventions and different strategies of the following three films: Sands of Iwo Jima (1949), Platoon (1986), and Top Gun (1986).

Measurement with an automated oscillometric wrist device with position sensor leads to lower values than measurements obtained with an automated oscillometric arm device from the same manufacturer in elderly persons

Introduction : Le monitoring de la tension artérielle à domicile est recommandé par plusieurs guidelines et a été montré être faisable chez la personne âgée. Les manomètres au poignet ont récemment été proposés pour la mesure de la tension artérielle à domicile, mais leur précision n'a pas été au préalable évaluée chez les patients âgés. Méthode : Quarante-huit participants (33 femmes et 15 hommes, moyenne d'âge 81.3±8.0 ans) ont leur tension artérielle mesurée avec un appareil au poignet avec capteur de position et un appareil au bras dans un ordre aléatoire et dans une position assise. Résultats : Les moyennes de mesures de tension artérielle étaient systématiquement plus basses avec l'appareil au poignet par rapport à celui du bras pour la pression systolique (120.1±2.2 vs. 130.5±2.2 mmHg, P < 0.001, moyenneidéviation standard) et pour la pression diastolique (66.011.3 vs. 69.7±1.3 mmHg, P < 0.001). De plus, une différence de lOmmHg ou plus grande entre l'appareil au bras et au poignet était observée dans 54.2 et 18,8% des mesures systoliques et diastoliques respectivement. Conclusion : Comparé à l'appareil au bras, l'appareil au poignet avec capteur de position sous-estimait systématiquement aussi bien la tension artérielle systolique que diastolique. L'ampleur de la différence est cliniquement significative et met en doute l'utilisation de l'appareil au poignet pour monitorer la tension artérielle chez la personne âgée. Cette étude indique le besoin de valider les appareils de mesures de la tension artérielle dans tous les groupes d'âge, y compris les personnes âgées.

Use of active personal dosemeters in interventional radiology and cardiology: Tests in hospitals - ORAMED project

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

Existential values transformation in all organ transplantation: A qualitative prospective study.

Organ transplantation offers a treatment of choice for patients suffering from end stage illnesses. The aim of this IRB approved prospective qualitative study was to analyze patients’ psychological concerns from their inclusion on the waiting list for first organ transplantation (TX) (T1; N=71; kidney, K=30; liver, Li=11; lung, Lu=15; heart, H=15) and six months after TX (T2; N=49; K=15; Li=10; Lu=14; H=10). Semi-structured interviews were conducted at home or in a place selected by patients. Qualitative pattern analysis (QUAPA) of the verbatim transcriptions was applied. T1 (K) Patients maintained an apparent normality (87%), building emotional protection (23%), and developing a fatalist attitude towards life (43%). (Li) Physical limits were set to spare energy until TX (73%). Illness led to reevaluation of life values (66%). (Lu) Physical and psychological self-protection was prioritized when health declined (67%). Modified life values, fatalism (33%) and spirituality (27 %) were mentioned. (H) Patients husbanded physical (80%) and psychological (67%) resources and self-protection. Modified life values and fatalist attitude towards life were reported (40%). T2 (K) New perspective on life was described, with increase of empathy towards others (20%). (Li) Positive identity and life values modifications (60%), greater openness towards others, closeness to significant ones (30%) and a more self-centered attitude (30%) prioritizing the essential (20%) were reported. Lack of respect of life values generated anger (40%). (Lu) Setting existential priorities and increase in spirituality (64%), along with the development of new life values, greater openness to others (57%) and closeness to significant ones (21%) were underlined. Lack of respect of human values induced negative feelings (36%). Self-centered attitudes, setting limits to other people were mentioned (29%). (H) Change in life values with setting life priorities was reported (70%) with increase in spirituality, and the lack of respect of life values generated anger (50%). Self-centered attitudes were reported (60%). TX not only comes with positive physical benefits, but also with positive existential values and psychological transformation, and the development of a more altruistic attitude and humanistic values.
