Les cuisines collectives du Québec comme outil de valorisation des ressources comestibles du fleuve, de l’estuaire et du golfe du Saint-Laurent

Travail dirigé présenté en vue de l’obtention du grade de Maîtrise ès sciences en nutritionLe St-Laurent regorge de ressources comestibles durables justifiant l’opportunité de les valoriser par des actions collectives en nutrition publique. L’objectif est d’explorer le rôle des cuisines collectives (CC) du Québec dans la valorisation des ressources maritimes locales incluant le sébaste, dont l’abondance est anticipée. Une collecte de données fut menée par questionnaire auto-administré en ligne incluant 21 questions documentant l’utilisation, les freins, l’intérêt pour les ressources du St-Laurent et la faisabilité d’intégrer le sébaste. Un total de 35 coordonnateurs de CC a participé. Les freins globaux sont: le coût , le goût , le manque de connaissances, l’accessibilité et la difficulté de juger de la fraicheur . Les répondants rapportent une faible utilisation régulière des ressources du St-Laurent ou ignorent la provenance des ressources . Un intérêt est exprimé pour les intégrer. Pour le sébaste, son usage éventuel est possible si le prix était modique voir nul, des outils seront cependant nécessaires pour son intégration dans l'assiette québécoise. L’utilisation des ressources maritimes du St-Laurent en CC offre des opportunités d’éducation alimentaire dans ces lieux visant la réduction de l’insécurité alimentaire

Grossesses extra utérines successives et bilharziose tubaire chez une touriste française

La bilharziose est la seconde endémie parasitaire mondiale et ses atteintes génito urinaires sont bien décrites. Les grossesses ectopiques (GEU) sur obstruction tubaire par les oeufs de bilharziose sont rapportées dans les populations africaines. La bilharziose affecte aussi les voyageurs mais l'atteinte de l’appareil génital féminin est plus rare. Nous rapportons un cas exceptionnel de deux GEU successives sur bilharziose tubaire chez une patiente d'origine Française, sept ans après un voyage touristique au Mali, la première découverte sur pièce de salpingectomie et la seconde ayant nécessité une salpingotomie controlatérale avec une injection de  méthotrexate, deux mois plus tard.Key words: Grossesse extra utérine, bilharziose tubaire, tromp

Measurements of Salinity in the Coastal Ocean: A Review of Requirements and Technologies

Salinity, a measure of the dissolved salts in seawater, is a fundamental property of seawater and basic to understanding biological and physical processes in coastal waters. In the open ocean long term salinity measurements are identified as necessary to understand global climate studies, hydrological cycle, and circulation. In the coastal oceans, information on salinity is critical to understanding biological effects on ecosystem function such as disease, nursery grounds, or harmful algal blooms and on physical processes such as freshwater runoff estuarine mixing, and coastal currents. While the importance of salinity is recognized, little attention has been given to making routine measurements as to the location and frequency of such measurements. These issues were addressed in a workshop concerned with salinity measurements in coastal oceans, requirements for such, and measurment technology

Gender differences in the long-term effects of a nutritional intervention program promoting the Mediterranean diet : changes in dietary intakes, eating behaviors, anthropometric and metabolic variables

Long-term adherence to principles of the Mediterranean diet (MedDiet) following a nutritional intervention promoting the Mediterranean food pattern in Canadian men and women is not known. Moreover, gender differences in dietary and metabolic profile in such an intervention context has never been addressed. Objective was to determine gender differences in long-term effects of a 12-week nutritional intervention program promoting the adoption of the MedDiet and based on the Self-Determination Theory (SDT) on dietary intakes, eating behaviors, anthropometric and metabolic variables, in men and women presenting cardiovascular risk factors. Methods Sixty-four men and 59 premenopausal women were recruited. The 12-week nutritional program used a motivational interviewing approach and included individual and group sessions. A food frequency questionnaire was administered to evaluate dietary intakes from which a Mediterranean score (Medscore) was derived and the Three-Factor Eating Questionnaire allowed assessment of eating behaviors. Measurements were performed at baseline and after the 12-week nutritional intervention, and then at 3 and 6-month post intervention. Results No gender difference was observed in changes in the Medscore during the nutritional intervention and follow-up. However, the Medscore returned towards baseline values during follow-up in men and women (P <0.0001). Men reported larger decreases in red and processed meat and larger increases in whole fruit intakes than women (P = 0.03 and P = 0.04, respectively). Men showed a greater decrease in habitual susceptibility to disinhibition than women (P = 0.03). A gender by time interaction was found for waist circumference, i.e. men had lower waist circumference at the end of the intervention as well as at follow-up than at baseline while women’s waist circumference decreased in response to the intervention only (P = 0.05). As for metabolic variables, changes observed in total-cholesterol (C) to HDL-C ratio, triglyceride levels and triglycerides to HDL-C ratio were more pronounced in men than in women after the intervention as well as at follow-up (P =0.03). Conclusions Our results indicate that the 12-week nutritional intervention based on the SDT leads to more pronounced beneficial changes in long-term dietary intakes in men than in women and to greater improvements in metabolic profile in men

Differences between men and women in dietary intakes and metabolic profile in response to a 12-week nutritional intervention promoting the Mediterranean diet

Few studies have compared men and women in response to nutritional interventions but none has assessed differences between men and women in the response to a nutritional intervention programme based on the self-determination theory (SDT) and using the Mediterranean diet (MedDiet) as a model of healthy eating, in a context of CVD prevention and within a non-Mediterranean population. The present study aimed to document differences between men and women in changes in dietary, anthropometric and metabolic variables, in response to a nutritional intervention programme promoting the adoption of the MedDiet and based on the SDT. A total of sixty-four men and fifty-nine premenopausal women presenting risk factors for CVD were recruited through different media advertisements in the Québec City Metropolitan area (Canada). The 12-week nutritional programme used a motivational interviewing approach and included individual and group sessions. A validated FFQ was administered to evaluate dietary intakes from which a Mediterranean score (Medscore) was derived. Both men and women significantly increased their Medscore in response to the intervention (P < 0·0001). Men showed a significantly greater decrease in red and processed meat (-0·4 (95 % CI -0·7, -0·1) portions per d) and a greater increase in fruit (0·9 (95 % CI 0·2, 1·6) portions per d) intakes than women. Significant decreases were observed for BMI and waist circumference in both men and women (P = 0·04). Significant greater decreases were found for total cholesterol (total-C):HDL-cholesterol (HDL-C) (-0·2; 95 % CI -0·4, -0·03) and TAG:HDL-C (-0·2; 95 % CI -0·4, -0·04) ratios in men than in women. When adjusting for the baseline value of the response variable, differences between men and women became non-significant for red and processed meat and fruit intakes whereas significant differences between men and women (i.e. larger increases in men than women) were observed for legumes, nuts and seeds (0·6 (95 % CI 0·2, 1·0) portions per d) and whole-grain products (0·5 (95 % CI 0·01, 1·0) portions per d) intakes. For metabolic variables, differences between men and women became non-significant for total-C:HDL-C and TAG:HDL-C ratios when adjusted for the baseline value of the response variable. The present results suggest that the nutritional intervention promoting the adoption of the Mediterranean diet and based on the SDT led to greater improvements in dietary intakes in men than in women, which appear to have contributed to beneficial anthropometric and metabolic changes, more particularly in men. However, the more deteriorated metabolic profile found in men at baseline seems to contribute to a large extent to the more beneficial changes in CVD risk factors observed in men as compared with wome

Effects of a nutritional intervention program based on the self-determination theory and promoting the Mediterranean diet

Our objective was to determine gender differences in the impact of a nutritional intervention based on the selfdetermination theory and promoting the Mediterranean diet on changes in eating-related self-determined motivation and adherence to the Mediterranean diet. Changes in eating-related self-determined motivation were larger in men than in women in response to the intervention and at follow-up, but the magnitude of change decreased with time in both genders. Changes in eating-related self-determined motivation were positively associated with changes in the Mediterranean diet adherence in response to the intervention and at follow-up in men only, suggesting that the nutritional program seems to fit better men than women
