Uterine Fibroid Embolisation for Symptomatic Uterine Fibroids: A Survey of Clinical Practice in Europe

Item does not contain fulltextPURPOSE: To assess current uterine fibroid embolisation (UFE) practice in European countries and determine the clinical environment for UFE in different hospitals. MATERIAL AND METHODS: In May 2009, an invitation for an online survey was sent by e-mail to all members of the Cardiovascular and Interventional Radiologic Society of Europe, representing a total number of 1,250 different candidate European treatment centres. The survey covered 21 questions concerning local UFE practice. RESULTS: A total of 282 respondents completed the questionnaire. Fifteen questionnaires were excluded because they were doubles from centres that had already returned a questionnaire. The response rate was 267 of 1,250 centres (21.4%). Ninety-four respondents (33%) did not perform UFE and were excluded, and six centres were excluded because demographic data were missing. The remaining 167 respondents from different UFE centres were included in the study. Twenty-six percent of the respondents were from the United Kingdom (n = 43); 16% were from Germany (n = 27); 11% were from France (n = 18); and the remaining 47% (n = 79) were from other European countries. Most centres (48%, n = 80) had 5 to 10 years experience with UFE and performed 10 to 50 procedures annually (53% [n = 88]) of respondents). Additional demographic data, as well as specific data on referral of patients, UFE techniques used, and periprocedural and postprocedural, care will be provided. CONCLUSION: Although UFE as an alternative treatment for hysterectomy or myomectomy is widespread in Europe, its impact on the management of the patient with symptomatic fibroids seems, according to the overall numbers of UFE procedures, somewhat disappointing. Multiple factors might be responsible for this observation

Uso de modelação matemática para projeto de câmaras mecanizadas de floculação em série em estações de tratamento de água The use of mathematical modeling to the design of continous flow completely mixed chambers in series for flocculation in water treatment plants

A metodologia encontrada na literatura para a otimização do gradiente de velocidade médio em reatores de mistura completa, com câmaras em série de escoamento contínuo, a partir de ensaios em reator estático tipo jarteste, baseia-se em modelos matemáticos que descrevem a cinética dos encontros entre partículas durante a floculação. Considerando-se que a aplicabilidade desta metodologia tem-se revelado inconsistente, como observado por diversos autores, este trabalho propõe uma metodologia racional para utilizar e otimizar os dados experimentais obtidos em reatores estáticos e, utilizando modelos matemáticos, obter dados para o projeto de floculadores mecanizados em série em estações de tratamento de água.<br>The existing methodology in the literature to optimize the velocity gradients in continuous flow completely mixed reactors using batch test data (static reactors) is based on mathematical models that describe the flocculation kinetics. Since this methodology has been shown to be inconsistent, as observed by several researchers, this work was carried out in order to propose a rational methodology to optimize the static reactors experimental data to obtain the design parameters of mechanized flocculation systems for water treatment plants
