Clinical Meaning of Ascites in Patients with Endomyocardial Fibrosis

OBJECTIVE: To evaluate the clinical meaning of ascites and the main features of patients with ascites and endomyocardial fibrosis. METHODS: We studied 166 patients with endomyocardial fibrosis (mean age 37 years, 114 women) treated over the last 20 years. Ventriculography findings, surgery or necropsy confirmed the diagnosis in all patients. Most patients belonged to New York Heart Association Functional Class III/IV (134, 83.7%). Eighty-one (50.6%) had biventricular, 28 (17.5%) had right ventricular, and 51 (31.8%) had left ventricular involvement. During follow-up, 56 patients died. RESULTS: Ascites was present in 67 (41.8%) patients, and right ventricular involvement was present in 59 (88%). In the comparison between patients with or without ascites, those with ascites had higher mortality (49.2% and 24.7%, respectively). Patients with ascites had a higher incidence of edema (95% vs. 43%), hepatomegaly (5.8cm vs. 4.1cm), mean right atrium pressure (19.3 vs. 12mmHg), and final right ventricle diastolic pressure (18.7 vs. 12.9mmHg). Also, patients with ascites had a longer history of illness (5.1 and 3.9 years, respectively) and had atrial fibrillation more frequently (44.7% vs. 30.1%). CONCLUSION: Ascites was observed in less than 50% of cases of endomyocardial fibrosis and was associated with greater involvement of the right ventricle and with a longer duration of the disease, thus being a characteristic of a worse prognosis.

Adquisició d'imatges en infraroig proper de baixa alçària sobre zones d'interès al Montseny (I)

En aquest informe, fem una primera avaluació d'un sistema basat en un mini-UAV, operat per l'empresa CATUAV (www.catuav.com), sobre una zona a l'est del Parc Natural del Montseny (PNM) tot comparant amb imatges adquirides l'any anterior sobre la mateixa zona, amb sistemes i plataformes aèries de primer nivell per l'Institut Cartogràfic de Catalunya i que utilitzem com a referent de qualitat. Tot assumint que les imatges produïdes pels UAV són d'una qualitat inferior als sistemes convencionals de teledetecció aerotransportada, si la qualitat i operativitat són encara suficients, aquests sistemes, donat el seu cost, poden constituir una eina important per adquirir informació d'alta resolució pel control de l'evolució de camps abandonats, de l'estat de la vegetació de ribera, de l'estat fitosanitari de cobertes forestals i plagues, de la distribució d'espècies invasores, de les conseqüències d'actuacions de restauració o aclariment del bosc, de l'impacte dels visitants etc. En concret, en aquest informe avaluem el sistema de CATUAV pel que fa a: 1) Operativitat del vol i adquisició de les imatges sobre una zona prèviament assenyalada com objectiu; 2) Operativitat del producte en quant a la localització i orientació de les imatges sobre el terreny; i 3) Qualitat radiomètrica i geomètrica de les imatges.

Reconsideration of dimensions and curve fitting practice in economics ellaborating on Georgescu-Roegen’s economic methodology

This paper is to examine the proper use of dimensions and curve fitting practices elaborating on Georgescu-Roegen’s economic methodology in relation to the three main concerns of his epistemological orientation. Section 2 introduces two critical issues in relation to dimensions and curve fitting practices in economics in view of Georgescu-Roegen’s economic methodology. Section 3 deals with the logarithmic function (ln z) and shows that z must be a dimensionless pure number, otherwise it is nonsensical. Several unfortunate examples of this analytical error are presented including macroeconomic data analysis conducted by a representative figure in this field. Section 4 deals with the standard Cobb-Douglas function. It is shown that the operational meaning cannot be obtained for capital or labor within the Cobb-Douglas function. Section 4 also deals with economists "curve fitting fetishism". Section 5 concludes thispaper with several epistemological issues in relation to dimensions and curve fitting practices in economics.

AIDS prevention: consensus and dissension regarding the meaning

Aim: In Western Europe, HIV/AIDS prevention has been based on the provision of information intended to lead the public to voluntarily adapt their behaviour so as to avoid the risk of virus transmission. Whether conveyed in a written or oral form, the messages of prevention are essentially verbal. Sociolinguistic research confirms that, even within a given culture, the meaning attributed to lexical items varies. It was hypothesised that understandings of the terms used in HIV/AIDS prevention in French-speaking Switzerland would vary, and research was undertaken to identify the level and nature of this variation both between and among those who transmit (prevention providers) and those who receive (the public) the messages. Method/issue: All HIV/AIDS prevention material available in French-speaking Switzerland in 2004 was assembled and a corpus of 50 key documents identified. Two series of lexical items were generated from this corpus: one composed of technical terms potentially difficult to understand, and the other, of terms used in everyday language with implicit, and therefore potentially variable, meaning. The two lists of terms were investigated in qualitative interviews in stratified purposive samples of the general public (n=60) and prevention providers (n=30), using standard socio-linguistic methodology. A further quantitative study (CATI) in the general population (17 - 49 yrs.; n=500) investigated understandings of 15 key prevention terms found in the qualitative research to have been associated with high levels of dissension. Results/comments: Selected aspects of the results will be presented. In illustration: meanings attributed to the different terms in both the public and the providers varied. For example, when a relationship is described as "stable", this may be understood as implying exclusive sexual relations or long duration, with an interaction between the two traits; the term "sexual intercourse" may or may not be used to refer to oral sex; "making love" may or may not necessarily include an act of penetration; the pre-ejaculate is qualified by some as sperm, and by others not... Understanding of frequently used "technical" terms in prevention was far from universal; for example, around only a half of respondents understood the meaning of "safer sex". Degree of understanding of these terms was linked to education, whereas variability in meaning in everyday language was not linked to socio-economic variables. Discussion: Findings indicate the need for more awareness regarding the heterogeneity of meaning around the terms regularly used in prevention. Greater attention should be paid to the formulation of prevention messages, and providers should take precautions to ensure that the meanings they wish to convey are those perceived by the receivers of their messages. Wherever possible, terms used should be defined and meanings rendered explicit.
