The proportion of centres returning the ERA-EDTA Registry questionnaires has decreased considerably in recent years. Demographic information, based on the response rate of centres in 1994 (44%), does not allow reasonable projections for management of renal failure in Europe. To encourage the participation of non-responding centres, the timing was right to(More)
BACKGROUND The new Centre Questionnaire, mainly based on the collection of epidemiological data, was launched in 1996 and the overall response rate of centres for the 15 countries constituting the European Union (EU) reached 82.2% (66-100%) for 1995. RESULTS We could derive the following information for a general population of 372.6 million. In 1995, the(More)
A modified neural network based on adaptive resonance theory (ART) was trained with the records of 211 psychiatric inpatients (74 schizophrenic, 50 unipolar depressed, 34 bipolar depressed, 20 bipolar manic, 33 other) who improved by at least 40 points of the GAFS during 8 weeks of treatment. Thereafter, a comparison was made between the clinical response(More)
Aviv, and released in October 1996. An improved version is Introduction under evaluation. The Registry has at its disposal a permanent office, based The incidence and prevalence of end-stage renal failure in London, with permanent staff. This office is run by a (ESRF) continue to increase despite the many Managing Director and should issue and collect all(More)
Clinical prediction of suicide is a complicated task. The focus for improved suicide risk detection is on the subgroup of individuals whose high suicide risk remains unrecognized by clinicians. We sought to evaluate the accuracy of Fuzzy Adaptive Learning Control Network (FALCON) neural networks, a nonlinear algorithm, in identification of this subgroup.(More)
BACKGROUND Patients who die within 90 days of commencing renal replacement therapy (RRT) may be recorded by some centres and not others, and hence data on mortality and survival may not be comparable. However, it is essential to compare like with like when analysing differences between modalities, centres and registries. It was decided, therefore, to look(More)
BACKGROUND The prevalence of Renal Replacement Therapy (RRT) is rising steadily, worldwide and in Europe. One reason for this is an increasing number of patients starting RRT, but improving survival on RRT may also be contributing. MATERIAL AND METHODS In an ERA-EDTA Registry study we have examined survival of patients with Standard Primary Renal Disease,(More)
BACKGROUND Medically serious suicide attempts have been recognized as the most important predictor of suicide. The Computerized Suicide Risk Scale based on backpropagation neural networks (CSRS-BP) has been recently found efficient in the detection of records of patients who performed medically serious suicide attempts (MSSA). OBJECTIVES. To validate the(More)
PRIMARY OBJECTIVES There are many known suicide risk factors (SRF) common to major psychiatric disorders, but their impact on suicide vulnerability remains unclear. We used FALCON (Fuzzy Adaptive Learning Control Network) to evaluate those impacts. METHODS Staff psychiatrists completed computerized suicide risk scales (CSRS-III) including 21 SRF for 612(More)
