应用营养风险筛查2002方法对天津市三级甲等医院住院患者营养风险、营养不足筛查、营养支持情况调查

Objective To investigate the nutritional risks, undernutrition, and nutritional support among inpatients in tertiary hospitals in Tianjin using Nutritional Risk Screening 2002 (NRS2002). Methods Inpatients in six departments in two tertiary hospitals in Tianjin (Tianjin Nankai Hospital and Tianjin Chest Hospital ) were consecutively enrolled from March 2005 to March 2006. Their nutritional risks were screened using NRS 2002, and the nutritional support was investigated. Results A total of 1200 inpatients received nutritional screening, and 93.0% of them underwent NRS 2002 scoring. The prevalence of undernutrition was 9. 8% and the prevalence of nutritional risk was 42. 8%. Of these patients, 241 patients (46.4%) with NRS2002≥3 received nutrition support, and 244 patients (35.9%) with NRS2002 ＜3 received nutritional support Conclusions NRS2002 is suitable for nutritional risk screening among inpatients. Inpatients usually have nutritional risks or undernutrition. However, physicians at different levels in different regions have different awareness of such risks or conditions, and the clinical application of nutritional supports sometimes are inappropriate.     

新疆地区三级甲等医院住院患者营养风险、营养不良(不足)、超重和肥胖发生率及营养支持应用状况

Objective To investigate the incidences of nutrition risks, malnutrition ( undernutrition),overweight, and obesity, and nutrition support in tertiary hospitals in Xinjiang Uigur Autonomous Region. Methods Using fixed-point consecutive sampling, we collected the clinical data of inpatients in 6 departments of five tertiary hospitals in Xinjiang. According to the Nutrition Risk Screening 2002 (NRS 2002 ) published by European Society for Parenteral and Enteral Nutrition, patients were graded as at nutritional risk when their NRS 2002 scores ≥3 and as malnutrition when the body mass index (BMI) was ＜ 18.5 kg/m2 (or albumin ＜ 30 g/L). NRS 2002 screening was performed on the next morning after a patient was admitted. The nutrition supports within 2 weeks after admission were also investigated. The relationship between nutrition risks and nutrition support was analyzed.Results A total of 4036 inpatients were investigated, among them 3913 patients received NRS 2002 screening.The malnutrition (undernutrition) rate and the proportion of patients at nutritional risk were 8.4% and 34. 2%, respectively. The percentage of nutrition support was 10. 2%, which included parenteral nutrition (8. 5% ) and ena simple, fast and convenient tool for the investigation of nutrition risks and can provide a basis for reasonable nutrition support Therefore, it should be widely applied in clinical practice.     

营养风险筛查2002的临床应用和分析

Objective To evaluate the clinical application of Nutritional Risk Screening 2002 (NRS 2002) in inpatients.Methods Totally 400 inpatients who were admitted to Tianjin Tianhe Hospital from Novem- ber 2008 to March 2009 were enrolled in this study.Physical examinations,including body height and body meas-urement,were performed the next morning after admission.The nutritional status was evaluated with NRS 2002.Results In all 400 inpatients.NRS 2002 was strongly practicable in 306 patients (76.5%) and weakly practica-ble in 94 patients (23.5%);Ninety-six patients (24.0%) had nutritional risks,which were most common in the department of internal medicine and the Department of neurology.The average age of patients with nutritional risks was (79.0±11.4) years,which was significantly higher than that of patients without nutritional risks [(58.1±15.8) years] (P<0.01).Conclusion NRS 2002 is effective and practicable in evaluating the nutritional status of inpatient.     

广西中小医院住院患者营养风险原因调查

Objective To investigate the causes of nutritional risks among inpatients in middle and small hospitals in Guangxi Zhuang Autonomous Region of China. Methods All the screened subjects were surveyed through classified collection of medical records and telephone follow-up. Factors including education background of patients and their family members, career, income, residence, medical payment methods, grade of hospital, and awareness of nutrition were analyzed. Results Lower education background of patients and their family members,less income, and self-funded health care payment were significantly associated with higher nutritional risks ( P ＜0. 01 ). The scores of malnutrition risks were significantly lower in patients whose careers were involved with culture, education and health and in patients whose family members had higher education levels (P ＜ 0.01 ). The nutrition risk was also significantly higher in patients from the rural areas than those from urban areas ( P＜0.01 ). It was also significantly higher in middle and small hospitals than in tertiary hospitals ( P＜0.01). Patients who had good awareness of nutritional knowledge had significantly lower incidence of nutritional risk (P ＜ 0. 01 ). Conclusion Low education level and poor economy in Guangxi are the main reasons for high nutritional risks.     

112例炎症性肠病患者的营养风险筛查

Objective To assess the nutritional risk of patients with inflammatory bowel disease (IBD).Methods The nutritional status of 112 IBD patients from PUMC Hospital were evaluated by Nutritional Risk Screening 2002 (NRS 2002).Using Chinese standard,a body mass index (BMI) that was lowered than 18.5 kg/m~2 according to clinical material was regarded as malnutrition,and the score was recorded as 3.The se-verity of ulcerative colitis (UC) was evaluated using True-Love criteria as mild,moderate,and severe.Crohn's disease (CD) was evaluated using Harvey-Bradshaw Index as in remission stage (≤4),moderately active stage (4-8),and severely actively stage (≥9).Results All these 112 patients,including 70 UC cases and 42 CD cases,were evaluated by NRS2002.Forty-five patients (40.2%) were judged as at the risk of malnutrition.The incidence of malnutrition was significantly higher in CD patients than in UC patients (52.4% vs.32.9%,P<0.05).It was also significantly correlated with the severity of disease.In patients with severe IBD,the rate of mal-nutrition evaluated by BMI according to clinical material was significantly lower than the rate of nutritional risk.Con-clusions The risk of malnutrition is high in IBD patients.NRS 2002 can be used for nutritional risk screening.

Lunasin is prevalent in barley and is bioavailable and bioactive in in vivo and in vitro studies

Lunasin, a unique 43-amino acid peptide found in a number of seeds, has been shown to be chemopreventive in mammalian cells and in a skin cancer mouse model. To elucidate the role of cereals in cancer prevention, we report here the prevalence, bioavailability, and bioactivity of lunasin from barley. Lunasin is present in all cultivars of barley analyzed. The liver and kidney of rats fed with lunasin-enriched barley (LEB) show the presence of lunasin in Western blot. Lunasin extracted from the kidney and liver inhibits the activities of HATs (histone acetyl transferases), yGCN5 by 20% and 18% at 100 nM, and PCAF activity by 25% and 24% at 100 nM, confirming that the peptide is intact and bioactive. Purified barley lunasin localizes in the nuclei of NIH 3T3 cells. Barley lunasin added to NIH 3T3 cells in the presence of the chemical carcinogen MCA activates the expression of tumor suppressors p21 and p15 by 45% and 47%, decreases cyclin D1 by 98%, and inhibits Rb hyperphosphorylation by 45% compared with the MCA treatment alone. We conclude that lunasin is prevalent in barley, bioavailable, and bioactive and that consumption of barley could play an important role of cancer prevention in barley-consuming populations.     

Salmonellas in pigs and animal feeding stuffs in England and Wales and in Denmark

A comparison has been made between the incidence of salmonellas in pigs and feeding stuffs in England and Wales and in Denmark. In Denmark there is veterinary legislation requiring the sterilization of imported and home produced feed ingredients of animal origin. There is no such legislation in England and Wales. In Denmark 0·3% of resterilized imported meat and bone meal was contaminated with salmonellas. This compared with 23% of meat and bone meal in England and Wales and 20-27% of other ingredients of animal origin. In England and Wales salmonellas were isolated from 7% of caecal samples and 6% of lymph node samples, while in Denmark they were isolated from 3% of caecal samples and 4% of lymph node samples. In England and Wales 25 serotypes were found in both pigs and feeds and these included nearly all the most prevalent human pathogens. In Denmark four of the six serotypes in pigs had been found in resterilized feed. One notable difference between the two studies was the very wide range of serotypes found in pigs in England and Wales and the narrow range in Denmark. A second was that Salmonella typhimurium formed 15% of all Salmonella strains isolated from pigs in England and Wales, and 60% of those in Denmark.     

Management of pregnancy and childbirth in England and Wales and in France

This paper reviews national data on obstetric and neonatal practices in England and Wales, and in France between 1970 and 1980. The data have been derived from national statistics and surveys on national samples of births in 1970, 1975 and 1980 in England and Wales, and 1972, 1976 and 1981 in France. The analysis shows that there was no major difference in pregnancy outcome, but wide variations in medical practices, and their trend over time. The main differences were: in England and Wales a higher number of antenatal visits, a higher percentage of inpatient admissions during pregnancy, a higher rate of induction, more episiotomies, a higher rate of resuscitation at birth, and admission to neonatal special care units; in France, a higher rate of caesarean sections before and during labour, some evidence of a more active management of labour, and a longer hospital post-natal stay. These differences in practice reflect differences in objectives and assessment of the effectiveness of care between the two countries: they point out the need for better monitoring and evaluation of obstetric and neonatal practices.     

Research and teaching in social and preventive medicine and in public health

Summary Both public health and social and preventive medicine are characterised by the common goal of promoting, maintaining and improving health and preventing disease, and both are concerned with a population-related, preventive and environmental perspective. But whereas public health is interdisciplinary and goes far beyond the medical focus, social and preventive medicine is medically based and forms a bridge between public health and medical practice. Research in a department of social and preventive medicine serves to support preventive and medico-social activities in medical practice as well as in public health. This is illustrated by results from research conducted at the author's department during the last twenty years. Examples are research in support of smoking cessation activities, and research used for the planning of care for the elderly. Both the research and the teaching activities of the department take into account the population focus of public health as well as the focus on individual medicine in clinical practice.

Forschung und Lehre in Sozial-und Präventivmedizin und öffentlicher Gesundheit

Zusammenfassung Sowohl das Gebiet der öffentlichen Gesundheit als auch dasjenige der Sozial-und Präventivmedizin sind durch das Ziel der Förderung, Erhaltung und Verbesserung der Gesundheit sowie der Krankheitsvorbeugung gekennzeichnet, und beide beschäftigen sich mit einer bevölkerungsbezogenen, präventiven und umweltbezogenen Perspektive. Aber während die öffentliche Gesundheit stark interdisziplinär ist und weit über den medizinischen Fokus hinausreicht, ist die Sozial-und Präventivmedizin ein medizinisches Fach und stellt eine Brücke zwischen der öffentlichen Gesundheit und der ärztlichen Praxis dar. Die Forschung in einem Institut für Sozial-und Präventivmedizin dient der Förderung präventiver und sozialmedizinischer Tätigkeiten in der ärztlichen Praxis wie auch in der öffentlichen Gesundheit. Dies wird durch die Forschungstätigkeit des Instituts des Autors aus den letzten 20 Jahren illustriert, wobei Beispiele aus den Gebieten der Förderung der Raucherentwöhnung und der Betreuung behinderter Betagter dargestellt werden. Sowohl in den Forschungs-als auch in den Lehrtätigkeiten des Instituts finden der Bevölkerungsbezug der öffentlichen Gesundheit wie auch der individualmedizinische Ansatz der ärztlichen Praxis ihren Ausdruck.

La recherche et l'ensignement en médecine sociale et préventive et en santé publique

Résumé La santé publique aussi bien que la médecine sociale et préventive sont caractérisées par le but commun de promouvoir, maintenir et améliorer l'état de santé et de prévenir les maladies, et elles s'orientent vers une perspective de population, de prévention et environnementale. Mais la santé publique est interdisciplinaire et va loin au-delà de la médecine, tandis que la médecine sociale et préventive est basée sur la médecine et représente le lien entre la santé publique et la pratique médicale. La recherche d'un institut de médecine sociale et préventive sert à appuyer les activités préventives et médico-sociales au cabinet médical aussi bien qu'en santé publique. Cela est illustré par des résultats de recherches conduites dans les vingt années passées à l'institut de l'auteur, et les exemples sont tirés de la recherche en appui de la promotion de la cessation de fumée et de la planification de la prise en charge des personnes âgées et handicapées. Les activités de recherche et de l'enseignement de l'institut tiennent compte de la perspective de population cacactéristique de la santé publique, aussi bien que de la dimension de médecine individuelle caractéristique de la pratique clinique.

Eggs enriched in omega-3 fatty acids and alterations in lipid concentrations in plasma and lipoproteins and in blood pressure

Effects of dietary eggs enriched with omega-3 fatty acids on lipid concentrations in plasma and lipoproteins and blood pressure were determined in 11 men and women in two groups. Group 1 consumed four omega-3 eggs per day during the first 4-wk period and four control eggs for the second 4-wk period. Group 2 ate the same number of eggs in the reverse order. Mean plasma cholesterol concentration was significantly increased by control eggs (P less than 0.01) but unchanged by omega-3 eggs. Mean plasma triglyceride concentration was decreased by omega-3 eggs but increased by control eggs. Both systolic and diastolic blood pressures were significantly lowered by omega-3 eggs in group 1 whereas only systolic pressure was significantly decreased on omega-3 eggs in group 2. The control eggs did not change blood pressure. In conclusion, the omega-3 eggs may be more healthful than the control eggs.     

Prevalence and Trends in Overweight in Mexican-American Adults and Children

Overweight and obesity have been increasing in many countries. Our objective is to describe the trends in overweight and obesity occurring in the Mexican-American population in the United States. Data on measured height and weight for Mexican Americans come from the following surveys: the Hispanic Health and Nutrition Examination Survey (HHANES, 1982–84), the Third National Health and Nutrition Examination Survey (NHANES III, 1988–94), and NHANES 1999–2002. In 1999–2002, 73% of Mexican-American adults were overweight and 33% were obese. Obesity increased between NHANES III and NHANES 1999–2002, from 24% to 27% for men and from 35% to 38% for women. Increases were also seen for children and adolescents. The Mexican-American population in the United States, both children and adults, is showing trends in overweight and obesity over time that are similar to those seen in other segments of the U.S. population and indeed in many countries
