In institutions and at home, some patients may have difficulty mobilizing and undressing, or refusing to put on their underwear. It is therefore likely that weighing dressed patients is a common practice. The overestimation of the body weight thus obtained could lead to an error in the evaluation of the nutritional status. The aim of the study was to determine the extent to which adult patients dressed versus underwear could alter their nutritional status. Fifty-one patients were included. Dressed weighing overestimated the actual weight of 1.6 ± 0.6 kg and induced an overestimation of nutritional status classification in almost 14% of cases. In addition, the weight of the clothes was different according to the sex and the conditions of outside temperature. These results suggest that it is desirable as much as possible to weigh all adult patients in underwear. 相似文献

Background
Food safety has become an absolute necessity in all countries. As a result, Morocco has taken several measures and actions to develop food safety and food-borne disease control.Objective
This study aimed to highlight the level of improvement in the quality assurance of meat and meat products in Morocco.Method
It is based on a non-exhaustive review of the regulatory texts governing food safety in the country, as well as a statistical study on establishments of meat and meat products adopting a self-checking system and approved by the National Office of Sanitary Safety of Food.Results
Morocco has introduced several laws and regulations requiring sanitary control of food products. Also, the number of establishments of meat and meat products adopting a system of self-control and approved by the National Office of Sanitary Safety of Food has improved significantly. It has increased from 58 in 2007 to 273 in 2016.Conclusion
The adoption of self-monitoring systems allows better access to international markets, improved quality of food products and a considerable reduction in microbial contamination. 相似文献94.

Objectives
We aimed to describe the epidemiology of Candida bloodstream infection in an intensive care unit (ICU) in Reunion Island.Methods
We performed a retrospective cohort study and evaluated 63 candidemia episodes, which occurred between January 2004 and December 2015 in the ICU of a University Hospital in St-Pierre.Results
The incidence rate of candidemia in the ICU was estimated at 7.6%. Candida albicans was the most common yeast pathogen species recovered (54%), followed by Candida glabrata (17%), Candida tropicalis (12%) and Candida parapsilosis (10%). Between 2012 and 2015, we also observed a modification of antifungal use.Conclusion
The epidemiology of candidemia in Reunion Island is characterized by the predominance of Candida albicans and by the relative importance of Candida tropicalis. This pattern corresponds to a model of epidemiological transition between the one usually observed in tropical areas and the one observed in temperate countries. 相似文献95.

Since 2005, forgoing live-support (FLS) is allowed by the French law (known as the Leonetti law) for end-of-life patients only. This study aims at describing the variations over time in the use of the following methods to end life: FLS, brain death and cardiopulmonary resuscitation failure (CPR failure). It is a single retrospective study from 2007 to 2012. The Cochran-Armitage trend test is used in the statistical analysis. Over six years, 263 of the 5100 children who were hospitalized in our intensive care unit died, which represents a 5.2% mortality rate. FLS increased yearly from 31% of the deaths in 2007, to 71% in 2012 (P = 0.0008). The rate of CPR failure decreased over the same period (P = 0.0015). The rate of brain death remained constant. Following to the Leonetti law, FLS increase, and palliative cares develop without any increase of mortality. 相似文献
