The European NEAT Program: An Integrated Approach Using Acamprosate and Psychosocial Support for the Prevention of Relapse in Alcohol-Dependent Patients With a Statistical Modeling of Therapy Success Prediction

ALCOHOLISM, Issue 10 2002
Isidore Pelc
Background A multicenter, prospective study was conducted in five European countries to observe outcome in alcohol misusers treated for 24 weeks with acamprosate and various psychosocial support techniques, within the setting of standard patient care. Methods Patients diagnosed as alcohol dependent using DSM-III-R criteria were treated, for 24 weeks, with acamprosate and appropriate psychosocial support. Potential predictor variables were recorded at inclusion. Drinking behavior was monitored throughout; the proportion of cumulative abstinence days was the principal outcome measure. The influence of baseline clinical and demographic variables on outcome was assessed using multiple regression analysis. Adverse events were recorded systematically. Results A total of 1289 patients were recruited; 1230 took at least one dose of the drug and provided at least one set of follow-up data; 543 (42.1%)patients were observed for the full 24-week period. The overall proportion of cumulative abstinence days was 0.48. Multiple physical and psychiatric comorbidities and a history of drug addiction were negatively correlated with outcome, as were, to a lesser extent, multiple previous episodes of detoxification, unemployment, and living alone. Older age and stable employment were positively associated with outcome. The difference in the unadjusted proportion of cumulative abstinence days between countries was significant (p < 0.001) but less so when adjusted for the predictive factors identified in the multivariate model (p < 0.019). Overall, outcome was not influenced by the nature of the psychosocial support provided. Adverse events were generally mild, with gastrointestinal disorders, which occurred in 21.5% of patients, being the most frequent. Conclusions This open-label study confirms the efficacy and safety of acamprosate in the treatment of alcohol dependence in the setting of standard patient care. Treatment benefit was observed irrespective of the nature of the psychosocial support provided. Predictors of the response to treatment were identified; their heterogeneous distribution within the study population explained, at least in part, the differences in outcome between countries.

Investigating information retrieval support techniques for different information-seeking strategies

JOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, Issue 8 2010
Xiaojun Yuan
We report on a study that investigated the efficacy of four different interactive information retrieval (IIR) systems, each designed to support a specific information-seeking strategy (ISS). These systems were constructed using different combinations of IR techniques (i.e., combinations of different methods of representation, comparison, presentation and navigation), each of which was hypothesized to be well suited to support a specific ISS. We compared the performance of searchers in each such system, designated "experimental," to an appropriate "baseline" system, which implemented the standard specified query and results list model of current state-of-the-art experimental and operational IR systems. Four within-subjects experiments were conducted for the purpose of this comparison. Results showed that each of the experimental systems was superior to its baseline system in supporting user performance for the specific ISS (that is, the information problem leading to that ISS) for which the system was designed. These results indicate that an IIR system, which intends to support more than one kind of ISS, should be designed within a framework which allows the use and combination of different IR support techniques for different ISSs.

Hepatic tissue engineering for adjunct and temporary liver support: Critical technologies

LIVER TRANSPLANTATION, Issue 11 2004
Christina Chan
The severe donor liver shortage, high cost, and complexity of orthotopic liver transplantation have prompted the search for alternative treatment strategies for end-stage liver disease, which would require less donor material, be cheaper, and less invasive. Hepatic tissue engineering encompasses several approaches to develop adjunct internal liver support methods, such as hepatocyte transplantation and implantable hepatocyte-based devices, as well as temporary extracorporeal liver support techniques, such as bioartificial liver assist devices. Many tissue engineered liver support systems have passed the "proof of principle" test in preclinical and clinical studies; however, they have not yet been found sufficiently reliably effective for routine clinical use. In this review we describe, from an engineering perspective, the progress and remaining challenges that must be resolved in order to develop the next generation of implantable and extracorporeal devices for adjunct or temporary liver assist.

Cardiopulmonary resuscitation training for undergraduate medical students: a five-year study

MEDICAL EDUCATION, Issue 3 2002
Colin A Graham
Background Cardiopulmonary resuscitation (CPR) training for undergraduate medical students and junior doctors has been noted to be poor in the past. Attempts have been made over the last decade to improve CPR training for all health professionals. Aim This study aimed to determine if CPR training for undergraduate medical students in a single institution improved after initial concerns in 1992, and to observe trends in CPR training over five years. Methods Prospective single centre observational cohort survey by means of a 2-page self completed questionnaire to final year undergraduate medical students at the University of Glasgow (1993,97 inclusive). Results Mean annual response rate 58% (range 48% , 67%). 99% of responders had been trained in basic life support during undergraduate training. The use of simulated arrests for training increased significantly. CPR training was concentrated in the first and final years. Training in all aspects of advanced life support increased, as did the students' confidence in these techniques. Student satisfaction with the amount of basic life support training increased very significantly and there was a small, but significant increase in student satisfaction with advanced life support training. Overall confidence at the prospect of being a member of the resuscitation team on qualification did not increase. Conclusions There has been a sustained improvement in CPR training at this institution since 1993. Improvements in the training of specific advanced life support techniques does not lead to improved overall confidence in using these skills on qualification. Advanced life support training requires further expansion. [source]

Novel double catheter technique in complex percutaneous coronary interventions

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, Issue 6 2006
Imad A. Alhaddad MD
Abstract We present a novel double catheter technique for successful complex intervention of a very old proximal left circumflex chronic total occlusion (>10 years old). Prior attempts of guide wire passage using bare wire alone, over-the wire balloon or microcatheter support techniques were unsuccessful. © 2006 Wiley-Liss, Inc. [source]
