消渴病与饮食关系密切,关于消渴病发病及治疗过程中的饮食、服药宜忌古已有之。其思想发源于《内经》,具体论述始于《伤寒杂病论》,在魏晋南北朝时期的诸多医籍中不断积累完善,到了唐代《外台秘要》和《医心方》时已经比较成熟,能够自成体系。通过系统总结唐以前医籍所载关于消渴病饮食及服药宜忌内容,分析其内在规律,有助于扩展和加深对糖尿病饮食宜忌相关的学术研究。  相似文献

IntroductionFor many years, nutrition of the elderly is of a special attention. The food policies wants to value the regional initiatives that can be slowed down, and new techniques of adapted food are in development. Following a tracking of malnutrition in an establishment for dependent elderly, a program of nutritional improvement was set up. It was decided to transform the dishes of the daily menu into small enriched, mixed, prehensile mouthfuls, with for objective to use the remaining capacities of the patients, to adapt the care to their rhythm, to answer their expectations and their nutritional needs.MethodThe agents of texture of the mouthfuls were adapted. Their enrichment and their presentation were specified, as well as the modalities of distribution, in order to allow an easy access as well by the patients, the nursing and the families. Cooled cupboards were used.ResultsThe residents found again the pleasure to eat by themselves, their self-respect and consequently covered better their needs. A decrease of the malnutrition prevalence was observed. Times of exchange with other establishments and a formation were set up to share this tool. Levers were identified to develop this concept under good conditions.ConclusionThe adapted enriched mouthfuls tool seems to be useful. Its application is inseparable of a voluntary multidisciplinary approach, anchored in the knowledge of the accompanied person and in the analysis of her global situation. This tool is adaptable not only in any structure welcoming dependent, old people or not, but also at home.  相似文献

Risk is a concept inherent in every medical procedure. It can be defined as the probability of an adverse event in a defined population over a specified period of time. In the frame of food allergy management, it might be related to a diagnostic procedure, a treatment, or the consumption of foods. The risk of an adverse event can also be augmented by individual factors. This rostrum article discusses various aspects faced by children with food allergies in the light of risk, and their practical implications. Identifying personal risks for severe reaction, such as unstable asthma, and correcting them whenever possible also contribute to a reduction of the risk inherent to food allergy. Among the facets discussed, oral food challenges (OFC) are the most common diagnostic procedures implying an inherent risk. The risk of OFCs can be minimized by correct indication and timing of the test, a safe setting, as well as by ensuring that the patient is otherwise well without potential stressor potentially increasing the risk of a more severe reaction. Oral immunotherapy (OIT) has been studied as a potential treatment for increasing the threshold dose for reaction, and thus reducing the risk of accidental reaction. Nevertheless, the procedure is not devoid of risk as the patients may and do often react during the course of the procedure. Ingestion of trace amounts in processed foods, mainly in community settings such as restaurants, schools, or day care, represents a potential risk of reactions, although for a minority of patients. Precautionary allergen labeling (PAL) is a widespread strategy to reduce the potential risk of reactions due to traces. However, PAL is currently inefficient due to inconsistent labeling, also not indicating a clear maximum amount possibly present in the manufactured food. Finally, cost-effectiveness needs to be considered in risk management, as many risk reduction procedures are clearly not cost-effective.  相似文献
