This Article breaks new ground toward contractual and institutional innovation in models of homeownership, equity building, and mortgage enforcement. Inspired by recent developments in the affordable housing sector and other types of public financing schemes, we suggest extending institutional and financial strategies such as time- and place-based division of property rights, conditional subsidies, and credit mediation to alleviate the systemic risks of mortgage foreclosure. Two new solutions offer a broad theoretical basis for such developments in the economic and legal institution of homeownership: a for-profit shared equity scheme led by local governments alongside a private market shared equity model, one of "bootstrapping home buying with purchase options".

Contexte: Parmi les complications de toute chirurgie, on retrouve l'embolie pulmonaire, dont l'issue est potentiellement fatale. Peu de travaux cependant ont été effectués pour étudier les facteurs de risques associés à une embolie pulmonaire après une chirurgie hépato-biliaire en particulier. Objectif: Le but de notre travail est d'étudier et comparer aux rares résultats existants les facteurs de risque ainsi que les conséquences d'une embolie pulmonaire post- hépatectomie. Les données pourront éventuellement être utilisées pour cibler les patients à risque et améliorer la prévention. Résultats: Le diagnostic d'embolie pulmonaire a été posé chez 24 patients (8%) au CT-scan dans la période post-opératoire. Le délai moyen entre l'opération et le diagnostic était de 5 jours (1-15j). La comparaison des patients du groupe EP (n = 24) au groupe Non-EP (n = 272) montre un BMI médian plus élevé (27 vs 24 kg/m2, p=0.006), un taux plus élevé de résections majeures (71 vs 43%, p=0.01) ainsi qu'une durée opératoire plus longue (310 vs 260 min, p=0.001). La durée totale d'hospitalisation était également supérieure dans le groupe EP (22 vs 11j, p<0.05), de même que la durée de séjour aux soins intensifs (3 vs 1j, p<0.05). La mortalité globale à 90j post-opératoires était de 3.3%, la mortalité du groupe EP étant nulle. Conclusion: Les résultats de cette étude rétrospective ont démontré l'association des embolies pulmonaires post-hépatectomie avec l'obésité, les hépatectomies majeures, ainsi qu'une longue durée d'opération. L'incidence non négligeable des embolies prouve la nécessité d'une prophylaxie thrombo-embolique.

This article starts a computational study of congruences of modular forms and modular Galoisrepresentations modulo prime powers. Algorithms are described that compute the maximum integermodulo which two monic coprime integral polynomials have a root in common in a sensethat is defined. These techniques are applied to the study of congruences of modular forms andmodular Galois representations modulo prime powers. Finally, some computational results withimplications on the (non-)liftability of modular forms modulo prime powers and possible generalisationsof level raising are presented.

The mechanisms of vascular calcifications in chronic renal failure are complex. Apart for clotting factors, vitamin K-dependent proteins include matrix Gla protein. Glutamic acid residues in matrix Gla protein are carboxylated by vitamin K-dependent gamma-carboxylase, which enables it to inhibit calcification. The purpose of this review is to discuss available evidence implicating vitamin K as a modifiable risk factor in the pathogenesis of vascular calcification in renal diseases.

The recent ACCORD and DIAD studies revealed results which could modify treatments and the screening of diabetes vascular complications. Indeed, ACCORD shows no benefit on the prevention of diabetes vascular complications by aggressive treatment of hypertension or the combined treatment of the dyslipidemia. The intensive treatment of the blood glucose, if associated with severe hypoglycemias, increases mortality. DIAD revealed 20% of silent myocardial ischaemia in diabetic patients but no beneficial effect on the cardiovascular mortality. A careful reading of these studies in the light of long term studies such as UKPDS and STENO reveals that these negative results are generated by a too short follow-up and too aggressive objectives. The long term studies reveal that more realistic objectives remain beneficial.

Osteoporosis of elderly is a growing medical, economic and health-care problem. It is due to the increase of the life expectancy and the number of osteoporotic fractures. With the new Swiss-specific tool FRAX and the development of inpatients fracture trajectory, we can better identify patients with high risk of fracture. An appropriate treatment can be proposed more quickly. The follow-up of bone markers increases the treatment efficiency. With a better identification, treatment and follow-up of osteoporosis of elderly patients, we can ameliorate the patient's quality of life and decrease the number of osteoporotic fractures with a good cost-effectiveness ratio.

Les fumeurs ont un poids corporel inférieur de 3 à 4 kg à celui des non-fumeurs, mais ils ont tendance à accumuler davantage de graisse au niveau abdominal. De par ce mécanisme, ainsi que par une toxicité directe du tabac sur les cellules du pancréas ou encore une augmentation de l'inflammation systémique, les fumeurs ont un risque accru de développer un diabète de type 2 comparativement aux non-fumeurs. À l'arrêt du tabac, la majorité des fumeurs prennent du poids et le risque de diabète est augmenté dans les premières années qui suivent l'arrêt. Les bénéfices de l'arrêt sur la mortalité ou les événements cardiovasculaires ne sont toutefois pas affectés par cette augmentation transitoire du risque métabolique.

Evidence-based medicine has enabled to approach disease in a more rational and scientific way. Clinical research has identified behaviours and risk factors that could cause disease often "silent" at the beginning, such as diabetes. Despite the clear impact of these evidences on public health, it seems that the individual risk perception level remains weak. To mention as well, the health professionals very often have a different views, which makes it difficult to communicate the risk with patients. In this article we describe the principles of risk perception, the diabetes related risk perception concerning cardiovascular complications, and suggest some practical strategies and tools which could improve risk communication in the everyday practice.
