Extracting new patterns for cardiovascular disease prognosis

EXPERT SYSTEMS, Issue 5 2009
Luis Mena
Abstract: Cardiovascular diseases constitute one of the main causes of mortality in the world, and machine learning has become a powerful tool for analysing medical data in the last few years. In this paper we present an interdisciplinary work based on an ambulatory blood pressure study and the development of a new classification algorithm named REMED. We focused on the discovery of new patterns for abnormal blood pressure variability as a possible cardiovascular risk factor. We compared our results with other classification algorithms based on Bayesian methods, decision trees, and rule induction techniques. In the comparison, REMED showed similar accuracy to these algorithms but it has the advantage of being superior in its capacity to classify sick people correctly. Therefore, our method could represent an innovative approach that might be useful in medical decision support for cardiovascular disease prognosis. [source]

Factors influencing twins and zygosity

PAEDIATRIC & PERINATAL EPIDEMIOLOGY, Issue 2005
Gary V. D. Hankins
Summary Zygosity is influenced by many factors. Monozygotic twins occur spontaneously in approximately 1 in 250 births and are felt to increase twofold with ovulation induction techniques. Monozygotic twinning also increases in proportion to the number of blastocysts transferred during in vitro fertilisation. In contrast, dizygotic twinning appears to be influenced by race, genetic factors, maternal age, fertility enhancing drugs, folic acid supplementation, and maternal nutritional status. [source]

Variation in rapid sequence induction techniques: current practice in Wales

ANAESTHESIA, Issue 1 2009
J. P. Koerber
Summary A questionnaire survey examining rapid sequence induction techniques was sent to all anaesthetists in Wales. The questionnaire presented five common clinical scenarios: emergency appendicectomy; elective knee arthroscopy with a symptomatic hiatus hernia; elective knee arthroscopy with an asymptomatic hiatus hernia; elective Caesarean section; and emergency laparotomy for bowel obstruction. Completed surveys were received from 421 anaesthetists, a 68% response rate. Rapid sequence induction was chosen by 398/400 respondents (100%) for bowel obstruction, 392/399 (98%) for Caesarean section, 388/408 (95%) for appendicectomy, 328/395 (83%) for symptomatic hiatus hernia but only 98/399 (25%) for asymptomatic hiatus hernia (p < 0.001). Trainees were more likely to use a rapid sequence induction technique than consultants and staff grades for the appendicectomy (p = 0.025), symptomatic hiatus hernia (p = 0.004) and asymptomatic hiatus hernia (p = 0.001) scenarios and were also more likely to use a thiopental,suxamethonium combination for rapid sequence induction (p < 0.001).
