Abstract

Introduction : Les patients ayant survécu à un séjour prolongé en soins intensifs risquent de développer une faiblesse musculaire acquise en soins intensifs ainsi qu’une dénutrition impactant négativement leur autonomie et leur qualité de vie. La période qui suit la sortie des soins intensifs (post-USI) est une période importante sur le plan nutritionnel afin de prévenir les séquelles de la dénutrition. L’objectif de ce mémoire est d’étudier la dépense énergétique mesurée par calorimétrie indirecte, ainsi que son évolution, au cours de l’hospitalisation en post-USI chez des patients ayant séjourné au moins 7 jours en soins intensifs. Actuellement aucune recommandation énergétique n’existe pour ces patients. &#13;&#13;Méthodes : Une étude longitudinale a été réalisée dans le but de récolter la dépense énergétique mesurée par calorimétrie indirecte à l’aide du Q-NRG de Cosmed® à deux périodes au cours de l’hospitalisation en post-USI au CHU de Liège. Les résultats ont ensuite été comparés à ceux estimés par deux équations de prédiction. &#13;&#13;Résultats : 40 calorimétries indirectes ont été réalisées chez 25 patients dont 10 en ont eu une et 15 en ont eu deux. Aucune évolution significative n’est observée entre les deux dépenses énergétiques durant la période en post-USI. La dépense énergétique se situe entre 1347 (1145,5-1923) et 1715 (1330-1880,5) kcal soit 18,9 à 21,9 kcal/kg par jour sur base du poids réel et 19,6 à 23,8 kcal/kg par jour sur base du poids de calcul. L’analyse de Bland et Altman a permis d’évaluer la concordance entre les résultats calorimétriques et ceux obtenus à l’aide de l’équation de Penn State et la recommandation de l’ESPEN (25 kcal/kg par jour). Cette analyse a révélé qu’aucune des deux équations n’est fiable pour déterminer les besoins énergétiques des patients en post-USI. &#13;&#13;Conclusion : Cette étude montre que les besoins énergétiques des patients en post-USI se situent entre 19,6 et 23,8 kcal/kg par jour sur base du poids de calcul et qu’il n’y a pas de différence au niveau de la dépense énergétique au cours de l’hospitalisation en post-USI. Introduction: Patients who have survived a prolonged ICU stay are at risk of developing ICU-acquired muscle weakness and undernutrition that negatively impacts their autonomy and quality of life. The period following discharge from the ICU (post-ICU) is an important time as far as nutrition is concerned in order to prevent the sequelae of undernutrition. The objective of this dissertation is to study the energy expenditure measured by indirect calorimetry, as well as its evolution, during the post-ICU hospitalization for patients having stayed at least 7 days in intensive care. Currently no energy recommendation exists for these patients. &#13;&#13;Methods: A longitudinal study was carried out with the aim of collecting energy expenditure measured by indirect calorimetry using the Cosmed® Q-NRG twice during post-ICU hospitalization at the University Hospital of Liege. The results were then compared with those estimated by two prediction equations. &#13;&#13;Results: 40 indirect calorimeters were performed on 25 patients. Ten of them had one and fifteen had two calorimeters. No significant changes were observed between the two energy expenditures during the post-ICU period. Energy expenditure ranged from 1347 (1145.5-1923) to 1715 (1330-1880.5) kcal, i.e., 18,9 to 21,9 kcal/kg per day based on actual weight and 19,6 to 23,8 kcal/kg per day based on calculated weight. Bland and Altman's analysis allowed to assess the consistency between the calorimetric results and those obtained using the Penn State equation and the ESPEN recommendation (25 kcal/kg per day). This analysis revealed that neither of the equations is reliable to determine the energy requirements of post-ICU patients. &#13;&#13;Conclusion: This study shows that the energy expenditure of post-ICU patients is between 19,6 and 23,8 kcal/kg per day based on the calculated weight and that there is no difference in energy expenditure during the post-ICU hospitalization.

Abstract

Gastrointestinal cancers, such as esophageal and gastric cancers, pancreatic cancers, hepatobiliary cancers, colorectal cancers and gastrointestinal stromal tumors, are frequently diagnosed at an advanced stage and have a dismal prognosis. Even in patients with potentially curative cancer, nearly 50\% will develop recurrent disease despite aggressive treatments. A number of biomarkers currently guide treatment decisions for patients with gastrointestinal neoplasms. Major technological advances in genomics have made it possible to identify critical genetic alterations in cancer, furthering oncology along the path to “personalized cancer medicine”. Future research efforts will focus on the identification of new biomarkers, moving existing biomarkers into earlier lines of therapy and evaluating new combinations of existing biomarkers and therapies.The aim of this Special Issue is to provide an overview of exciting new research in the area of gastrointestinal tumors that may establish innovative personalized management and precision medicine modalities for individualized care.

Abstract

In recent years, the industry has started to use parts printed by powder-based laser additive manufacturing (LAM) when precision and good mechanical properties are required. Applications can be found in the aerospace, automotive, and medical sectors. However, the powder materials available are often inadequate for contemporary processing tasks, and often generate process instabilities as well as porosities and defects in the resulting parts. This Special Issue, “New Frontiers in Materials Design for Laser Additive Manufacturing”, focuses on advances in material design and the development of laser additive manufacturing. Of particular interest are original papers dealing with metal and polymer powders for laser powder bed fusion or directed energy deposition. In this Special Issue, we are especially interested in answering the following questions: How can laser process parameters and material properties be adapted to the LAM process via the matrix modification (e.g., alloying, doping, compounding) of powders? How can powder properties like flowability, wetting, porosity, or (heterogeneous) nucleation be adapted to the LAM process via the surface modification of powders? How may calorimetry, high-speed videography, pyrometry, and online spectroscopy, as well as modeling, contribute to understanding dynamics of melting and recrystallization, in addition to the lateral distribution of the thermal process window?

Abstract

Everybody has made use of grease in their daily lives. The word “grease” originates from the early Latin word “crassus,” meaning fat. For our purposes, in this Special Issue, we will be focusing on lubricating grease, for publication in the eponymous journal Lubricants. According to ASTM, lubricating grease may be defined as “a solid-to-semi-fluid product of dispersed thickening agents in a liquid lubricant”. Other functional ingredients, such anti-wear and extreme pressure additives, may be included, with the overall goal of inducing special properties/functionalities. Grease is a very complex lubricant. We have never had a Special Issue focusing on this key product, and lubricating greases are often underrepresented in the technical literature. In recent years, there has been significant progress in research on greases, ranging from the specific chemical formulation of greases for special applications to how grease interacts with various surfaces, tribological advances in grease properties, new techniques for grease property measurements, etc. Recently, greases have also been evolving, as they and play a key role in the lubrication of electric vehicles. We aim to select the top research avenues and papers worldwide related to lubricating greases to form this compilation. This Special Issue wishes to be the first of its kind, and we plan to make this an annual exercise, where our compendium aims to discuss the latest developments worldwide encompassing all areas related to greases.
