Describing the dietary intake of breast cancer survivors participating in the EXPINKT™ programme. A pilot study.

Background: In 2015, 3292 New Zealand women were diagnosed with breast cancer. A breast cancer diagnosis tends to evoke lifestyle change and in particular dietary change. There is a substantial amount of research about the potential causes of breast cancer and dietary risk factors, but less on diet during breast cancer treatment and even less on what women are consuming post treatment completion. There can be lasting impacts from treatment including poor nutrient intake, unwanted weight change and undesirable weight changes. These affect nutritional status and possibly recurrence risk. To date, the guidelines for what breast cancer survivors should consume post treatment are based on limited, but suggestive evidence for reducing the risk of recurrence. There is a lack of research on dietary habits in women with breast cancer in this country. In order to potentially influence lifestyle changes, it is important that breast cancer survivors have their actual diet documented. Objective: The aim of this thesis is to describe the diet in breast cancer survivors and compare it to recommendations and guidelines. This will guide further research in this area, here in New Zealand and potentially aid the production of specific national dietary recommendations for breast cancer survivors. Design: This is a descriptive pilot study of women participating in the EXPINKT™ programme in Dunedin who completed breast cancer treatment at least six weeks prior. Participants received a questionnaire including a section on characteristics and a Food Frequency Questionnaire (FFQ), measuring dietary intake for the preceding three months. Results: The questionnaire was returned by 35 women. Nutrient intakes derived from the FFQ were slightly higher than that of the New Zealand women population of the same age group. The cohort did not meet the Ministry of Health recommendations for the food groups of vegetables, meat, poultry and seafood as well as breads and cereals. There were no meaningful differences for any nutrients between treatments, although of the women who received either chemotherapy or hormone therapy, nutrient intakes tended to be higher than those women who did not receive that treatment. There were meaningful differences for protein 22.8 g (95 % CI: 1.64, 43.9), riboflavin 0.88 mg (95 % CI: 0.11, 1.64), folate 162 µg (95 % CI: 22.4, 301), calcium 587 mg (95 % CI: 99.7, 1074), zinc 3.21 mg (95 % CI: 0.23, 6.20) and potassium 1153 mg (95 % CI: 85.7, 2220) in women that were diagnosed prior to 2013 as their confidence intervals did not cross zero. Education level and body mass index status had no association with nutrient intake, although a lack of tertiary education was associated with a lower intake of all food groups. Conclusion: Dunedin breast cancer survivors who participate in the EXPINKT™ programme do not meet the Ministry of Health’s food group recommendations for vegetables, meats and breads and cereals. To prevent the negative outcomes that may occur, there is a need for nutritional guidance in this population, particularly in New Zealand. Continued research is needed in order to determine what foods can reduce recurrence risk and what may increase it

La gestion d'un environnement dynamique lors de situations d'alerte (analyse des processus cognitifs et des activités collectives)

Cette thèse s intéresse à la gestion d alerte, activité complexe et dynamique qui s insère dans le cadre plus général des situations de crise. Cette activité se caractérise par des processus cognitifs spécifiques et par son aspect collectif. L objectif principal de la thèse correspond à l analyse et à la modélisation de la dimension collective des processus cognitifs mis en œuvre lors de la gestion d alerte. Ce travail s organise autour de deux axes. D une part, l analyse des processus cognitifs et des activités collectives lors de deux exercices de gestion d alerte. D autre part, la mise en place de trois simulations de crise pour évaluer l influence de la complexité sur les stratégies collectives développées par les experts. Les résultats montrent que les prises d informations s effectuent majoritairement selon un mode coopératif vertical et augmentent avec la complexité de la situation à traiter, alors que les diagnostics s effectuent selon un mode collaboratif et restent constants.AIX-MARSEILLE1-BU Lettres (130012101) / SudocSudocFranceF

Structural and magnetic properties of the new ternary silicide Gd3Co2.48Si1.52

International audienceGd3Co2.48Si1.52 was obtained by arc-melting of the elements and subsequent annealing at 1073 K during 1 month. Its structure, determined from single-crystal X-ray diffraction data, derives from the W3CoB3-type structure with the space group Cmcm and the unit cell parameters a = 4.1185(3), b = 10.2970(7) and c = 12.8166(8) Å. Mixed occupancy between Co- and Si-atoms is observed for two crystallographic sites. Only few ternary compounds are known to crystallize with this structure-type. Magnetization measurements reveal at least one ferromagnetic transition at 180 K

The new ternary silicide Gd₅CoSi₂: Structural, magnetic and magnetocaloric properties

Gd5CoSi2 was prepared by annealing at 1003 K. Its investigation by the X-ray powder diffraction shows that the ternary silicide crystallizes in a tetragonal structure deriving from the Cr5B3-type (I4/mcm space group; a=7.5799(4) and c=13.5091(12) Å as unit cell parameters). The Rietveld refinement shows a mixed occupancy on the (8h) site between Si and Co atoms. Magnetization and specific heat measurements performed on Gd5CoSi2 reveal a ferromagnetic behaviour below TC=168 K. This magnetic ordering is associated to an interesting magnetocaloric effect; the adiabatic temperature change ΔTad is about 3.1 and 5.9 K, respectively, for a magnetic field change of 2 and 4.6 T

Les activités de gestion d’alerte épidémiologique : les transformations induites par l’utilisation d’un système de surveillance en temps réel

This paper presents a study that investigated the management of epidemiological alerts. Alert management is a complex, distributed medical activity. It can be compared to the largest category of dynamic environment management. Two activities were examined. First, we analyzed traditional alert management activity with the MAD method (observations and interviews). Second, we analyzed and characterized alert management activities when supported by the computerized ASTER system (Alerte et Surveillance en TEmps Réel, alert and monitoring in real time). The second analysis was conducted with EORCA method, which is used to describe collective and complex activities. The results highlight various modifications to both the cognitive activity and team activities which were due to the use of the ASTER system
