PURPOSE: The purpose of this study was to evaluate short and long term results after esophageal cancer resection in patients older than 75. METHODS: We retrospectively analyzed the database of esophageal cancer surgically treated in our department between January 2003 and December 2009 to identify patients older than 75. The preoperative, operative, postoperative and long term characteristics were analyzed. RESULTS: Among 137 patient, 23 were older than 75. The histological subtype was adenocarcinoma in 100%. The surgical techniques were a "Lewis-Santy" procedure in 43%, a trans-hiatal resection in 22%, a "Sweet" procedure in 13%, a stripping in 13% and a McKeown procedure in 9%. The in-hospital postoperative mortality was 13%. The in-hospital postoperative morbidity (Dindo-Clavien Grade >2, deceased patients included) was 26%. In univariate analysis, no statistically significant risk factor of morbidity was found. A Charlson Comorbidity Index >2 was, in univariate analysis, the sole risk factor of postoperative mortality (p = 0.0362). The mean hospital stay was 22 +/- 12 days. The median survival was 24.2 months. The 5-year overall survival was 39% and the 5-year disease free survival was 26%.57% of long-term deaths were not cancer related. CONCLUSION: Esophageal surgery performed in selected patients older than 75 has an acceptable morbidity and mortality but when a severe complication occurs, it leads to death in half of the cases. Surgery enables a long term survival benefit. This study confirmed our attitude of not considering age as a contra-indication for esophageal surgery but rather considering general status, self-reliance and associated comorbidities for patients' selection.

The design of a multi-subject fMRI experiment needs specification of the number of subjects and scanning time per subject. For example, for a blocked design with conditions A or B, fixed block length and block order ABN, where N denotes a null block, the optimal number of cycles of ABN and the optimal number of subjects have to be determined. This paper presents a method to determine the optimal number of subjects and optimal number of cycles for a blocked design based on the A-optimality criterion and a linear cost function by which the number of cycles and the number of subjects are restricted. Estimation of individual stimulus effects and estimation of contrasts between stimulus effects are both considered. The mixed-effects model is applied and analytical results for the A-optimal number of subjects and A-optimal number of cycles are obtained under the assumption of uncorrelated errors. For correlated errors with a first-order autoregressive (AR1) error structure, numerical results are presented. Our results show how the optimal number of cycles and subjects depend on the within- to between-subject variance ratio. Our method is a new approach to determine the optimal scanning time and optimal number of subjects for a multi-subject fMRI experiment. In contrast to previous results based on power analyses, the optimal number of cycles and subjects can be described analytically and costs are considered. [less ▲]

From the early Middle Ages onwards devotional portraits are well attested but during the 15th century they occupy a prominent place in the pictorial production of the ancient Low Countries. If at first these portraits were largely reserved to princes and kings, they now spread into broader social circles. Bourgeois, nobles, ducal officials and clergy wanted to leave traces of their piety and their presence on earth. This resulted in an amplification and diversification without precedent of religious works including one or more portraits. In the course of the 16th century however this trend slackened.During the 15th and 16th centuries, the integration of a portrait into a religious composition can take many forms. The sponsor is often portrayed on his knees, hands clasped, but he can also act as privileged follower situated among the saints, or even take part in the scene itself, through the features of one of the protagonists. The corpus, comprising over 750 works for the 15th and 16th centuries, shows many variations of these basic formulas, suggesting a multiplicity of meanings and functions of these works. The specific nature of this pictorial production, mixing sacred and profane elements, asks for a study that does justice to this dual nature. The analysis establishes a classification based on a typology combining the physical structure of works (front / rear, central part / wings) and the symbolic structuring of the fictional space they show (how the sacred and the profane area are differentiated, the gradation or the fusion between both areas). It also takes into account the presence of figures of mediation, in particular the patron saints. The stylistic approach focuses initially on the iconographic language that is used and aims to identify the semantic units before referring to external textual sources (archives, literature of devotion etc.). These in turn play a vital role in better understanding the often complex motivations of the devotees who are portrayed. By their presence in the image they wish to express a prayer, a vow, and especially to ensure their salvation in the hereafter. But their portraits also reflect a concern for self-representation, as evidenced by sumptuous clothing, jewelry, emblems which indicate the social rank and the position they occupy in society. The article demonstrates the importance of a rigorous cluster analysis, which outlines the issues as they appear after the confrontation with all known iconographic parallels. [less ▲]

We consider the discrete version of the competitive facility location problem in which new facilities have to be located by a new market entrant firm to compete against already existing facilities that may belong to one or more competitors. The demand is assumed to be aggregated at certain points in the plane and the new facilities can be located at predetermined candidate sites. We employ Huff’s gravity-based rule in modelling the behaviour of the customers where the probability that customers at a demand point patronize a certain facility is proportional to the facility attractiveness and inversely proportional to the distance between the facility site and demand point. The objective of the firm is to determine the locations of the new facilities and their attractiveness levels so as to maximize the profit, which is calculated as the revenue from the customers less the fixed cost of opening the facilities and variable cost of setting their attractiveness levels. We formulate a mixed-integer nonlinear programming model for this problem and propose three methods for its solution: a Lagrangean heuristic, a branch-and-bound method with Lagrangean relaxation, and another branch-and-bound method with nonlinear programming relaxation. Computational results obtained on a set of randomly generated instances show that the last method outperforms the others in terms of accuracy and efficiency and can provide an optimal solution in a reasonable amount of time.

Multivalvular heart disease is not an uncommon situation, but the paucity of data for each specific situation does not allow the proposal of a standardised, evidence-based management strategy. This paper aims at reviewing the available evidence on the management of multivalvular disease, taking into account the interactions between different valve lesions, the diagnostic pitfalls and the strategies that should be considered in the presence of multiple valvular disease.

La durabilité des bétons au laitier de haut fourneau dépend fortement de l’activité hydraulique du laitier. Dans cette étude, un laitier algérien, caractérisé par une faible hydraulicité, est utilisé dans la fabrication de mortiers comme substituant du ciment à des taux de 0, 30 et 50%. En plus d’une caractérisation mécanique, l’effet du laitier sur la durabilité des mortiers est évalué par des essais de perméabilité à l’oxygène, de diffusion de chlorures en régime permanent ainsi que de conduction des ions chlore (essai accéléré ASTM). Les résultats montrent, malgré une faible réactivité du laitier, une amélioration de la perméabilité à l’oxygène à long terme (360 jours) pour les mortiers au laitier, particulièrement pour un taux de 50%. La présence du laitier réduit la perméabilité aux ions chlore, d’une part, en augmentant le temps de passage des chlorures à travers le mortier et, d’autre part, en diminuant le taux de diffusion. Par ailleurs, une faible conduction des chlorures est observée pour les mortiers au laitier, montrant une similitude avec les résultats d’essai de diffusion en régime permanent. [less ▲]

OBJECTIVES: The veneering process of frameworks induces residual stresses and can initiate cracks when combined with functional stresses. The stress distribution within the veneering ceramic as a function of depth is a key factor influencing failure by chipping. This is a well-known problem with Yttria-tetragonal-zirconia-polycrystal based fixed partial dentures. The objective of this study is to investigate the influence of veneer thickness on the stress profile in zirconia- and metal-based structures. METHODS: The hole-drilling method, often used for engineering measurements, was adapted for use with veneering ceramic. The stress profile was measured in bilayered disc samples of 20mm diameter, with a 1mm thick zirconia or metal framework. Different veneering ceramic thicknesses were performed: 1mm, 1.5mm, 2mm, 2.5mm and 3mm. RESULTS: All samples exhibited the same type of stress vs. depth profile, starting with compressive at the ceramic surface, decreasing with depth up to 0.5-1.0mm from the surface, and then becoming compressive again near the framework, except for the 1.5mm-veneered zirconia samples which exhibited interior tensile stresses. Stresses in the surface of metal samples were not influenced by veneer thickness. Variation of interior stresses at 1.2mm from the surface in function of veneer thickness was inverted for metal and zirconia samples. SIGNIFICANCE: Veneer thickness influences in an opposite way the residual stress profile in metal- and in zirconia-based structures. A three-step approach and the hypothesis of the crystalline transformation are discussed to explain the less favorable residual stress development in zirconia samples. [less ▲]
