Quette place pour l'automesure glycémique dans la prise en charge du diabète de type 2 [Which role for self-monitoring of blood glucose in type 2 diabetes?]

There is a sustained controversy in the literature about the role and utility of self-monitoring of blood glucose (SMBG) in type 2 diabetes. The study results in this field do not provide really useful clues for the integration of SMBG in the follow-up of the individual patient, because they are based on a misconception of SMBG. It is studied as if it was a medical treatment whose effect on glycemic control is to be isolated. However, SMBG has no such intrinsic effect. It gains its purpose only as an inseparable component of a comprehensive and structured educational strategy. To be appropriate this strategy cannot be based on the health care professionals' view on diabetes only. It rather has to be tailored to the individual patient's needs through an ongoing process of shared reflection with him.

Prise en charge de la mort in utero: quel bilan proposer ?

RÉSUMÉ Objectifs : Evaluer l'intérêt des examens paracliniques prescrits dans les morts du foetus in utéro pour aboutir à l'établissement d'un nouvel algorithme de prise en charge du bilan des morts in utero. Matériel et méthodes : Analyse rétrospective d'une série de 106 morts in utero recensées entre septembre 1989 et décembre 1998 dans le département de gynécologie - obstétrique du CHUV (maternité de type 3) à Lausanne. Nous avons défini la mort in utero à partir de la date limite de viabilité foetale. Seules les grossesses de 24 semaines ou plus ont été inclues dans cette série. Nous avons exclu les morts in utero survenues en cours d'interruption thérapeutique de grossesse ainsi que les cas présentant un dossier incomplet. La classification étiologique utilisée est celle décrite par Fretts. L'analyse a porté sur les différents examens demandés, ainsi que sur l'évaluation de leur pertinence dans l'établissement du diagnostic étiologique de chaque cas. La recherche de facteurs de risque significatifs a également été prise en considération. Nous avons comparé notre prise en charge aux données de la littérature, afin de proposer un nouvel algorithme. Résultats : L'étiologie de la mort foetale a pu être définie dans 90% des cas. Les causes principales en étaient les retards de croissance in utero (19,8 %), les anomalies congénitales et chromosomiques foetales (18,9%), les infections (15,1%), le décollement placentaire (7,5%), la prééclampsie (5,6%), le diabète maternel (3,8%). Le 18,9% restant se répartissant par petits nombres entre diverses autres causes. Dans 10,4% des cas nous n'avons pas trouvé d'explication à la mort in utero. Les examens les plus profitables dans le bilan de la mort in utero était l'autopsie foetale, qui était anormale dans 92,7% des cas examinés, l'anatomopathologie placentaire, anormale dans 93% des cas et le babygramme (radiographie du squelette foetal), pathologique dans 53% des cas. La sérologie maternelle infectieuse était informative dans 6,6% des cas. Conclusion : Nous présentons un protocole de prise en charge du bilan de la mort in utero différencié en fonction des circonstances entourant l'événement, afin de limiter les examens superflus.

Timing of Capacity Change: Models for Capital Intensive Industry

The suitable timing of capacity investments is a remarkable issue especially in capital intensive industries. Despite its importance, fairly few studies have been published on the topic. In the present study models for the timing of capacity change in capital intensive industry are developed. The study considers mainly the optimal timing of single capacity changes. The review of earlier research describes connections between cost, capacity and timing literature, and empirical examples are used to describe the starting point of the study and to test the developed models. The study includes four models, which describe the timing question from different perspectives. The first model, which minimizes unit costs, has been built for capacity expansion and replacement situations. It is shown that the optimal timing of an investment can be presented with the capacity and cost advantage ratios. After the unit cost minimization model the view is extended to the direction of profit maximization. The second model states that early investments are preferable if the change of fixed costs is small compared to the change of the contribution margin. The third model is a numerical discounted cash flow model, which emphasizes the roles of start-up time, capacity utilization rate and value of waiting as drivers of the profitable timing of a project. The last model expands the view from project level to company level and connects the flexibility of assets and cost structures to the timing problem. The main results of the research are the solutions of the models and analysis or simulations done with the models. The relevance and applicability of the results are verified by evaluating the logic of the models and by numerical cases.

The double-edged sword of social capital: Three essays on entrepreneurship in developing nations

ABSTRACT My study seeks to answer the main question: "how does entrepreneurs' social capital positively and negatively affect their resource mobilization efforts, and exploitation of entrepreneurial opportunity?" To answer this question, I develop a model for examining positive and negative effects of social capital on resource accumulation by entrepreneurs, and the subsequent effect of resource accumulation on the exploitation of entrepreneurial opportunity, and utilize data from Africa to ëmpirically test the relationships in this model. Developing nations are a suitable context because: a) They require entrepreneurship for economic development, b) They have received less attention in management and entrepreneurship research, c) Because of inadequately-developed institutions, entrepreneurs from developing nations face major resource mobilization challenges hence they often turn to their social ties for resources, and d) The communalistic and collectivistic nature of most developing nations -encouraging support and sharing of resources- may help us better understand how society's values and structures may contribute and also deduct firm resources. My study reveals that social capital contributes resources to entrepreneurs in developing nations at a cost that takes away resources, and that more resources but lower costs facilitate entrepreneurial opportunity exploitation. For entrepreneurs in developing nations, large networks, greater shared identity, and more trust are beneficial. To increase chances of raising more resources, entrepreneurs from communalistic societies should include network members from outside their communities. Besides providing financial support, policy-makers should develop training programs and advisory services on configuration of entrepreneurs' networks so as to achieve more resources at a low cost. My study insights can help improve entrepreneurs' resource accumulation efforts and the subsequent growth of their firms, leading to the overall economic growth of developing nations.

La prise en charge de l'hyper- tension artériette par des médecins en formation suit-elle les recommandations actuettes [Are the guidelines for the management of hypertensive patients followed by primary care residents and fellows?]

Numerous international guidelines are published which define how hypertensive patients should be managed. Are these guidelines followed and applicable? We have assessed the quality of management of 225 hypertensive ambulatory patients followed by young fellows in teaching for primary care medicine. The control rate defined by a blood pressure < 140/90 mmHg was 32,4%. In the last three visits, 60% of hypertensive patients had a blood pressure measurement. 79% of blood pressure readings ended with 0 or 5. Blood pressure control was identical whatever the comorbidities. In conclusion, the quality of management of hypertensive patients by in teaching fellow could potentially be improved. The actual recommendations are limited in their application. The control of high risk vascular patients is not better than those with a lower risk.

Du delirium au syndrome démentiel: prise en charge médicamenteuse dans les EMS fribourgeois [Management of elderly patients with delirium or dementia in Swiss nursing homes].

Management of elderly patients with delirium or dementia in Swiss nursing homes Dementia and delirium are among the most frequent medical conditions in older nursing home residents. Their management require a coordinated interdisciplinary approach, including for drug prescription. Using a systematic literature review of published meta-analyses and guidelines, prescription algorithms were developed adressing the pharmacological management of cognitive symptoms of dementia and delirium in older nursing home residents in the canton of Fribourg.
