L’évolution fatale d’une thrombose de la veine porte

La thrombose du système portal est rare et ses étiologies sont multiples. Nous rapportons le cas d’un jeune patient de 26 ans, sans antécédents pathologiques particuliers admis pour douleurs abdominales diffuses d’installation brutale. Le diagnostic de la thrombose porte a été établi par le scanner abdominal sans mise en évidence d’un foyer infectieux intra-abdominal. Le bilan biologique a mis en évidence une hyperleucocytose mais la procalcitonine était négative. Le traitement anticoagulant a été démarré le jour de l’admission et le patient est décédé le jour même.  

An Evaluation of the COVID-19 Pandemic and Perceived Social Distancing Policies in Relation to Planning, Selecting, and Preparing Healthy Meals: An Observational Study in 38 Countries Worldwide

Objectives: To examine changes in planning, selecting, and preparing healthy foods in relation to personal factors (time, money, stress) and social distancing policies during the COVID-19 crisis. Methods: Using cross-sectional online surveys collected in 38 countries worldwide in April-June 2020 (N = 37,207, Mage 36.7 SD 14.8, 77% women), we compared changes in food literacy behaviors to changes in personal factors and social distancing policies, using hierarchical multiple regression analyses controlling for sociodemographic variables. Results: Increases in planning (4.7 SD 1.3, 4.9 SD 1.3), selecting (3.6 SD 1.7, 3.7 SD 1.7), and preparing (4.6 SD 1.2, 4.7 SD 1.3) healthy foods were found for women and men, and positively related to perceived time availability and stay-at-home policies. Psychological distress was a barrier for women, and an enabler for men. Financial stress was a barrier and enabler depending on various sociodemographic variables (all p < 0.01). Conclusion: Stay-at-home policies and feelings of having more time during COVID-19 seem to have improved food literacy. Stress and other social distancing policies relate to food literacy in more complex ways, highlighting the necessity of a health equity lens.

Effect of source and rate of nitrogen fertilization on yield, fruit quality and leaf mineral composition of valencia orange trees grown in Riyadh, Saudi Arabia

This investigation. was carried out during 1992 and 1993 seasons to study the influence of ammonium sulfate and urea at different rates (0, 250, 500, 750, and 1000 g N/tree) on the yield, fruit quality and leaf mineral composition of Valencia orange trees growing in Riyadh. The results revealed that there were no significant differences in the yield, physical and chemical properties of the fruits due to sources of nitrogen applied. Whereas, rates of nitrogen markedly affected the yield and most of fruit properties in both seasons. In addition, yield and fruit properties were responded positively to increasing the rates of nitrogen up to 750 and 1000 g N/tree as compared with the control and the lowest rate of nitrogen. However, the nitrogen fertilization was more effective and pronounced in the second season than in the first one. Concerning leaf analysis, data showed that the application of ammonium sulfate as a nitrogen source produced a significant increase in the leaf nitrogen content as compared with applying urea. Furthermore, increasing nitrogen rates resulted in a significant increase in leaf nitrogen content than that of the control. No obvious effect was found in leaf macro or micronutrient contents between both sources of nitrogen applications. On the other hand, increasing rates of nitrogen caused marked increase in leaf Mg and Cu contents, slight increase in leaf Fe and Mn contents, and marked decrease in leaf K and Na contents as compared with the control. However, leaf P, Ca, and Zn contents were unaffected by the different rates of nitrogen application

An Infinite Plate with a Curvilinear Hole and Flowing Heat

In the present paper, we apply the complex variable method (Cauchy method) to derive exact expressions for the Goursat\u27s functions for the boundary value problem of infinite plate weakened by a curvilinear hole. The hole is conformally mapped on the domain outside a unit circle by means of a general rational mapping function. Also the stress components, when an initial heat is uniformly flowing in the perpendicular direction of the hole, are obtained, Some applications are investigated. The interesting cases, when the shape of the hole takes different famous formulas are included as special cases, The work of many previous authors can be considered as special cases of this work
