Osteosarcopenia (OS), which has become a global public health problem, is a geriatric syndrome in which sarcopenia and osteoporosis co-exist, leading to falls, fractures, and even varying degrees of disability in the elderly. The Dietary Inflammatory Index (DII) is a tool to measure the overall level of dietary inflammation in an individual, and the DII score is closely associated with the development of OS. This article reviews the basic concepts of DII and OS and their interrelationships, focusing on the associations between diet, inflammation, DII and OS, with the aim of providing a reference for dietary interventions in the prevention and control of OS patients.
ObjectiveTo investigate the effect of behavior intervention through diets and exercises on blood glucose controlling in patients with gestational diabetes mellitus (GDM), and to provide the basis for GDM therapy. MethodsA total of 116 patients with GDM diagnosed and treated in the Sixth Affiliated Hospital of Sun Yat-sen University between March 2011 and December 2012 were taken as our study objects, including 72 patients in the study group and 44 patients in the control group, based on their will. For patients in the study group, we carried out behavior interventions through diets and exercises, including dietary guidance, giving pamphlet and formulating exercise plan, while for patients in the control group, we only gave them oral guidance and publicity materials. The same questionnaire was used to collect all the patients' information. Follow-up was done once in every 3 days, and rechecking was performed 2 weeks later. The results of oral glucose tolerance test and the rate of pathoglycemia were compared in these groups before and after intervention. ResultsThe fasting blood glucose, 1- and 2-hour blood glucose were lowered after the behavior intervention in the study group (P<0.05), which were also significantly lower than the control group (P<0.05). Fasting blood glucose, 1- and 2-hour pathoglycemia was significantly lower in the study group than that in the control group and that before intervention (P<0.05). ConclusionCombination of diets and exercises can control levels of blood glucose in GDM patients, and is an important therapy for GDM.
Objective To investigate the influence of preoperative enteral nutrition with dietary fiber on the nutritional status of patients with colon colostomy diaplasis, and discuss its safety. Methods Forty preoperative colon colostomy diaplasis patients from West China Hospital treated between September 2013 and June 2014 were randomly assigned into trial group and control group with 20 in each. The baseline of the two groups was the same (all P > 0.05). The trial group was given enteral nutrition with dietary fiber before operation for seven days, while control group was given homogenate diet with equal quantity of energy and nitrogen content for the same period of time. All patients were being tested for nutritional indexes on the day of admission and on the fifth day after surgery. Meanwhile, other indexes such as the first time of flatus and defecation, abdominal distension, bellyache, and other adverse reactions were recorded too. Results There was no statistical difference in nutritional indexes on the day of admission and on the fifth day after surgery between two groups (P > 0.05). Patients with dietary fiber had significantly higher incidence of abdominal distension than the control subjects (P < 0.05), but other adverse reactions had no statistical differences between the two groups (P > 0.05). No anastomotic leakage occurred in both the two groups. Patients with dietary fiber had significantly earlier time of flatus than the control group (P < 0.05). Patients with dietary fiber had significantly lower incidence of diarrhea than the control subjects (P < 0.05). Conclusions The study suggests that it is safe and feasible to use enteral nutrition with dietary fiber for preoperative colon colostomy diaplasis patients. Using dietary fiber is helpful for intestinal function recovery and reduction of the occurrence of adverse reactions after surgery.
Objective To study the effect and feasibility of gradual oral diethylnitrosamine (DENA) induced liver cirrhotic model in rats under avoirdupois monitoring. Methods Fifty Wistar rats (6 weeks old) were divided into 3 groups: normal control group （n=10）, traditional DENA induction group (receiving traditional oral DENA treatment, n=20）, gradual DENA induction group (receiving gradual oral DENA treatment under avoirdupois monitoring, n=20). The weight, mortality and liver cirrhosis formation were observed. Results After 4 weeks of inducing cirrhosis, the weight of traditional DENA induction group 〔(234.9±27.1) g〕 was significantly lower than that of normal control group 〔(264.8±33.7) g, P＜0.05〕. After 8 weeks of inducing cirrhosis, the weight of traditional DENA induction group 〔(251.5±34.3) g〕 was significantly lower than that of normal control group 〔(303.2±49.4) g， P＜0.01〕 and gradual DENA induction group 〔(277.5±27.6) g， P＜0.05〕. However, the difference between normal control group and gradual DENA induction group was not remarkable (P＞0.05). The mortality in traditional DENA induction group (35%) was significantly higher than that in normal control group (0) and gradual DENA induction group (0)， P＜0.05. But the rate of cirrhosis formation both in traditional DENA induction group and gradual DENA induction group was 100%. Conclusion Oral DENA induced cirrhotic model in rats is a simple, reproducible and reliable technique. Gradual oral technique, in which DENA is given under avoirdupois monitoring, can improve rat’s security and reduce mortality.
As the eventual end of the cardiovascular disease, heart failure is aggravated or results in cachexia when the patient is under malnutrition or exposes to certain risk factors of diet mode during the long disease duration. Researches reveal that the diet has effects on patho-physiology, energy metabolism, inflammation and oxidative stress of heart failure. This article conducts a literature review on the association between diet and heart failure.
ObjectiveTo summarize the current advancement of the relationship between dietary factors and colorectal cancer in recent years, looking for more reasonable prevention measures. MethodsRelated literatures about the relationship between diet composition and the occurrence of colorectal cancer at home and abroad were collected to make a review. ResultsAmong the environmental factors, dietary factors had a close relationship with colorectal cancer, and was easy to control. Nowadays, it was believed that high animal fat, excessive alcohol consumption, consumption of fried, barbecue, and pickles may be positively associated with the occurrence of colorectal cancer. However, high fiber, high vitamin, high folic acid, the amount of minerals and trace elements in diet were negatively correlated with the occurrence of colorectal cancer. ConclusionsColorectal cancer occurs by environmental factors, genetic factors, and other factors. Diet model of people in different areas is not the same, the occurrence rate of colorectal cancer is also different, so it needs further study to explore its mechanism.
ObjectiveTo evaluate the dietary and nutritional status of elderly patients with chronic non-infectious diseases in community hospitals in order to make a reasonable dietary pattern for these patients. MethodsA total of 179 elderly patients with chronic non-infectious diseases in a community hospital of Chengdu from January to September 2014 were collected, and we investigated them on their dietary status and basic personal information. The desirable dietary pattern (DDP) score was adopted to evaluate their dietary and nutritional status. ResultsDDP score of the 179 patients with chronic non-infectious diseases in the community hospital was 91.47, and the dietary quality was relatively good. While the DDP scores of animal food and edible oil exceeded the maximum allowable value, DDP scores of the staple food, fish, eggs, vegetables and fruits were lower than the expected scores. ConclusionIt is suggested that meat and other animal food intake be reduced and replaced by regular intakes of poultry, fish and shrimp, and the intake of staple food, eggs, vegetables, fruits be increased to ensure a balanced diet.
Objective To systematically review current status of Chinese DRIs, and compare the similarities and differences between Chinese and global DRIs, so as to provide references for regulating Chinese DRIs. Methods Such database as PubMed, ISI Web of knowledge, The Cochrane Library, CBM, WanFang Data, CNKI and VIP were electronically searched from inception to May 31st, 2013. The reviewers independently screened studies according to inclusion and exclusion criteria, extracted data. Then, descriptive analysis was performed for basic information of literature, formulation of different DRIs, and DRIs distribution by different ages. Results Initially, a total of 588 articles were retrieved, 42 of which were finally included, involving 14 guidelines, 12 systematic reviews (SRs), and 16 original studies. The results showed that, WHO guidelines and global systematic reviews focused on iron and fat-soluble vitamins (A and D); the original studies in China focused not only on iron and vitamin A but also on protein, calcium, zinc, and selenium. The included guidelines focused mainly on population aged 3-18 years old and pregnant women; and except for those two kinds of population, SRs also paid attention to adults aged more than 18 years. The original studies of Chinese DRIs were concerned about all kinds of population, mainly focused adults aged 18-45 years and school children aged 6-12 years. Among 16 included original studies, 4 were concerned about men and 2 about women. Conclusion Chinese DRIs need urgent updates and supplement. As the largest developing country, China has different disease burdens, consumption levels, dietary patterns, nutrients’ content, and security levels, compared with developed countries and other developing countries. To develop evidence-based Chinese DRIs that are suitable for native health and Chinese local conditions, we should drawing lessons from the currently available best DRIs standards, methods and evidence based on Chinese actual conditions, disease burden, and expert opinion.
Objective?To study the existent dietary hygiene behavior and attitude among college students and to provide references for further education and management. Methods?A self-designed dietary hygiene-related questionnaire based on the KAP (knowledge-attitude-practice) model was conducted in Sichuan University students, with a method of proportionate sampling classified by sex, grade, and major. Results?College students’ hygienic habits were not good enough. It indicated that only 7.8% of the students were concerned about Hygiene License and 30.7% of them held that tableware should be sterilized before using. Besides, only 21% of the students washed hands before meals, 14.9% believed that a health certificate was required for foodservice employees, more than 80% students may buy food on stalls sometimes. Conclusion?A majority of students have requirements for hygienic situations while dining, but they do not know clear specific health standards. A number of students are not used to washing hands before dining. Moreover, lack of hygienic awareness is emphasized when they are facing food with potential safety problems. It is very necessary to strengthen health education and to improve hygienic behaviors in college students.
Objective This study employs Mendelian randomization analysis to explore the causal relationship between dietary habits and systemic lupus erythematosus (SLE). MethodsWe obtained data from the MRC-IEU database on five dietary habits as instrumental variables for exposure "never eating dairy products" "never eating eggs or foods containing eggs" "never eating sugar or foods/drinks containing sugar" "never eating wheat products" and "I eat all of the above". Summary data related to SLE were retrieved from the MRC-IEU database for the discovery cohort (designated as MSLE) and from a Finnish database for the validation cohort (recorded as FSLE). Two-sample Mendelian randomization analyses were conducted using inverse variance weighting (IVW), MR-Egger, weighted median, Simple Mode, and Weighted Mode methods to investigate the causal relationship between dietary habits and SLE. The MR-Egger intercept test was performed to assess the presence of horizontal pleiotropy, while the leave-one-out method was employed to verify the stability of the results, with Cochran’s Q test and funnel plots used to evaluate heterogeneity. ResultsMendelian randomization analysis indicated that never eating wheat products increases the risk of developing SLE (IVW: P<0.05). In contrast, there was no significant causal relationship between the consumption of dairy products, eggs or foods containing eggs, or the consumption of all of the above with SLE (IVW: P>0.05). Additionally, there was no significant causal relationship between never sugar or foods/drinks containing sugar and MSLE (IVW: P=0.877), although a potential causal association with FSLE was suggested (IVW: P=0.016). The MR-Egger intercept test indicated no evidence of horizontal pleiotropy (P>0.05). ConclusionNever eating wheat products may be an independent risk factor for SLE. However, the causal relationship between never sugar or foods/drinks containing sugar and SLE remains indeterminate.
