BACKGROUND: International comparisons of health care systems have shown a relationship at the macro level between a well-structured primary health care plan and lower total health care costs. The objective of this study was to assess whether provider continuity with a family physician is related to lower health care costs using the individual patient as the unit of analysis. METHODS: We undertook a study of a stratified sample of patients (age, sex, region, insurance company) for which 2 cohorts were constructed based on the patients' utilization pattern of family medicine (provider continuity or not). Patient utilization patterns were observed for 2 years. The setting was the Belgian health care system. The participants were 4,134 members of the 2 largest health insurance companies in 2 regions (Aalst and Liege). The main outcome measures were the total health care costs of patients with and without provider continuity with a family physician, controlling for variables known to influence health care utilization (need factors, predisposing factors, enabling factors). RESULTS: Bivariate analyses showed that patients who were visiting the same family physician had a lower total cost for medical care. A multivariate linear regression showed that provider continuity with a family physician was one of the most important explanatory variables related to the total health care cost. CONCLUSIONS: Provider continuity with a family physician is related to lower total health care costs. This finding brings evidence to the debate on the importance of structured primary health care (with high continuity for family practice) for a cost-effective health policy. [less ▲]

This article presents a new stability prediction tool. The method is based on the dynamic behaviour of both milling tool and workpiece, computed using finite element method. Dynamic behaviour is expressed under the form of transfer functions and used to predict stability lobes at each tool position. The unconditionally stable depth of cut is then stored and displayed on a graphic representation of the machined surface under the form of colour axis, named stability map. An application of the method on a Renault cylinder block is presented as an illustration. (C) 2006 Elsevier Ltd. All rights reserved. [less ▲]

Long-term care (LTC hereafter) concerns people who depend on help to carry out daily activities. It is mainly delivered informally by families and to a lesser extent formally by professional care assistants and nursing homes. Most EU governments are also involved in some way in the provision or financing of LTC services. Right now, the future of LTC provision appears to be gloomy, for demographic, societal and financial reasons. This TSE Note studies the strengths and weaknesses of three institutions providing LTC services - namely the family, the State and the private insurance market - and provides policy recommendations based on the view that governments should take the leadership towards a comprehensive approach of the dependency problem, while relying as much as possible on the family and the market.

The authors report their experience with operative treatment of 18 proximal fifth metatarsal stress fracture in 17 soccer players. Percutaneous intramedullary fixation with a 4.5 mm malleolar screw was used in 11 patients (group 1) and open intramedullary screw fixation associated with autologous cancellous bone grafting in 7 other (group 2). The average follow-up was 3.1 years. Clinical and radiographic union was obtained in all cases. The average return to full sports practice was 12 weeks. Refracture occurred in three players in the first group at 4.5, 5.2 and 6.0 months after return to full sport activity. They underwent reoperation with screw exchange, curettage of the fracture site and autologous cancellous bone grafting. No case of refracture was reported in the second group. On the basis of this series, intramedullary screw fixation associated with autologous cancellous bone grafting seems to be a reasonable primary treatment in high level soccer players. [less ▲]

Operative retrieval of two proximally migrated vena caval filters was performed in two patients, ages 42 and 45 years, respectively. In the first patient the filter was encrusted in the right ventricle, and in the second one the filter was found in the pulmonary artery. Both filters were retrieved under cardiopulmonary bypass via an incision in the right atrium and the pulmonary artery, respectively. These two observations underscore the risk of increased unwarranted indications and consequent higher complication rates of vena caval filters. [less ▲]

Introduction : Certaines tendinopathies (l’épicondylite, la tendinopathie rotulienne supérieure ou encore la tendinopathie d’Achille) demeurent rebelles malgré un traitement « classique » bien conduit : repos, orthèse, AINS, électrothérapie, kinésithérapie, infiltrations de corticoïdes, ondes de choc... Certains travaux, essentiellement in vitro, soulignent les potentialités réparatrices des plaquettes qui présentent la capacité d’accélérer la cicatrisation de différents tissus : os, muscles et tendons. Objectifs : Le but de notre étude préliminaire est d’objectiver l’effet « accélérateur » sur la réparation tendineuse suite à l’emploi d’injection de plasma enrichi en plaquettes (platelet-rich plasma ou PRP) car cette technique pourrait représenter une thérapeutique d’avenir en médecine physique et en traumatologie du sport. Méthodes : Nous avons sectionné et réalisé un défect de 5mm dans le tendon d’Achille de rats (N = 12). Quatre rats ont bénéficié d’une injection in loco de PRP et remis en liberté comme les autres dans leur cage. Trois rats (2 sans PRP et 1 avec PRP) sont euthanasiés à J5, J10, J20 et J30 et le tendon d’Achille en cours de régénération est disséqué et prélevé. Une étude biomécanique de traction jusqu’à rupture est réalisé à l’aide de « Cryo-jaw ». Résultats : L’analyse des résultats montre que la force développée pour obtenir la rupture tendineuse doit être plus importante pour les tendons ayant bénéficié d’une injection de PRP et ce dès J5. Discussion – Conclusion : Cette série préliminaire permet de montrer que les injections de PRP permettent une accélération de la cicatrisation tendineuse et une augmentation des valeurs de résistances à la traction. Une étude avec un plus grand nombre de sujets est en cours. [less ▲]

Growing amount of high dimensional data requires robust analysis techniques. Tree-based ensemble methods provide such accurate supervised learning models. However, the model complexity can become utterly huge depending on the dimension of the dataset. Here we propose a method to compress such ensemble using random tree induced space and L1-norm regularisation. This leads to a drastic pruning, preserving or improving the model accuracy. Moreover, our approach increases robustness with respect to the selection of complexity parameters. [less ▲]
