Effects of the composite of buckwheat-oat-pea on blood glucose in diabetic rats / 北京大学学报(医学版)

OBJECTIVE@#To study the effects of buckwheat-oat-pea (BOP) composite flour [buckwheat ∶ oats ∶ peas=6 ∶ 1 ∶ 1 (quality ratio)] on blood glucose in diabetic rats.@*METHODS@#In this study, 64 male Sprague-Dawley rats were divided into 8 groups by fasting blood glucose (FBG) and body weight: normal control group, model control group, metformin group, buckwheat group, oats group, BOP low-dose group (BOP-L), medium-dose group (BOP-M), and high-dose group (BOP-H). The rats in the normal control group were fed with normal diet, the rats in the model control group and metformin group were fed with a high-fat diet (HFD), and the rats in the buckwheat group, oats group, and BOP-L, BOP-M, BOP-H groups were fed with HFD containing 10% buckwheat flour, 10% oat flour, 3.3% BOP, 10% BOP, 30% BOP, respectively. The HFD in all the groups had the same percentage of energy from fat (45%). After 30 days, the rats fed with HFD received intraperitoneal injection of streptozotocin (30 mg/kg, once a week for two weeks) to establish diabetes mellitus. After the model was successful established, the rats were fed for another 28 days. During the study, the body weight, food intake/body weight (FI/BW) and water intake/body weight (WI/BW), food utilization rate, 24 h urine volume, FBG, glucose area under curve (GAUC) of oral glucose tolerance test were measured regularly. At the end of the study, the fasting serum glucose and insulin were measured, and homeostasis model assessment of insulin resistance (HOMA-IR) was calculated.@*RESULTS@#With the inducing of HFD and streptozotocin, compared with the normal control group, the rats in the model control group had higher FI/BW, WI/BW, 24 h urine volume, FBG, GAUC, HOMA-IR (P < 0.05), and lower body weight, food utilization rate (P < 0.05). Compared with the model control group, the rats in the three BOP groups all had higher body weight, food utilization rate (P < 0.05), and lower WI/BW, HOMA-IR (P < 0.05); the rats in the BOP-L and BOP-M groups had lower FI/BW, 24 h urine volume, FBG (P < 0.05), and the rats in the BOP-M group also had lower GAUC (P < 0.05). After the establishment of diabetes, there was no significant difference in blood glucose and the other indicators between the rats in the three BOP groups and the buckwheat group or the oats group (P>0.05).@*CONCLUSION@#The BOP had the effects of reducing blood glucose, insulin resistance and diabetic symptoms on diabetic rats, and had the value for further development and utilization.

Evaluation of a low-residue diet for bowel preparation of colonoscopy / 中华消化内镜杂志

Objective@#To evaluate the clinical value of a commercial low-residue diet (LRD) for bowel preparation of colonoscopy.@*Methods@#This study was a prospective, endoscopist-blind, and randomized controlled trial. Participants were randomly assigned to two groups according to administration of LRD: the experimental group and the control group. Bowel preparation quality, compliance and tolerability of the two groups were compared.@*Results@#A total of 61 patients were enrolled, with 32 in the experimental group and 29 in the control group. The outcomes were as follows: Boston Bowel Preparation Scale (BBPS) (7.8±1.0 VS 7.1±1.3, P=0.037), the rate of bowel preparation adequacy (87.5% VS 79.3%, P=0.388), compliance rate of dietary restriction (78.1% VS 55.2%, P=0.057), preparation completion rate (93.8% VS 93.1%, P=0.919), cecal intubation rate (both were 100.0%) and cecum arrival time (9.1±2.9 min VS 9.8±3.7 min, P=0.417), incidence of adverse (3.1% VS 3.4%, P=0.944), and hunger rate before colonoscopy (34.4% VS 48.3%, P=0.102).@*Conclusion@#The LRD for bowel preparation of colonoscopy significantly improves BBPS, but its effect on improving the bowel preparation adequacy, patient compliance and tolerability needs to be confirmed by further larger-scale trials.

Establishment of zebrafish model for non-alcoholic steatohepatitis / 中华肝脏病杂志

Objective@#To establish overfed zebrafish model for non-alcoholic steatohepatitis.@*Methods@#The wild-type zebrafish was fed 3 times a day with normal diet. Body length, weight, and triglyceride levels were measured after 20 days of feeding. The changes in expression of genes associated with cholesterol metabolism, lipid metabolism, endoplasmic reticulum stress, and inflammation were detected by quantitative PCR. Liver tissue sections were stained with H&E. Statistical analyses between groups were compared using t-test.@*Results@#The body length (0.71±0.014) cm and body weight (44.83±1.833) mg of model group were higher than that of control group (0.50±0.009) cm and body weight (19.33±2.753) mg (total body length = 12.36, total body weight = 7.71, P < 0.01). Triglyceride content in the model group was (59.15 ± 0.5612) μmol / L, higher than the control group (16.71 ± 0.3562) μmol / L (t = 63.84, P < 0.001). Quantitative PCR results showed that the expression of genes related to cholesterol synthesis in the model group was higher than that in the control group (P < 0.01). The expression levels of lipid production and lipid oxidation related factors in the model group were higher than the control group. The difference between the two groups was statistically significant (P < 0.05). The expression of inflammation-related factors in the model group was higher than that in the control group (P < 0.001), and the expression of genes related to endoplasmic reticulum stress in the model group was higher than that to control group (P<0.001). Liver H&E staining showed that the model group had pathological changes such as large bulla and vesicles compared to the control group.@*Conclusion@#A continuous 3 times 20 days of normal diet can simulate the disease characteristics of human non-alcoholic steatohepatitis in a zebrafish.

Avaliação dos custos diretos com terapia nutricional enteral em um hospital público / Assessment of direct costs with enteral nutritional therapy in a public hospital

Introdução: A desnutrição representa um alto custo hospitalar, decorrente de gastos com medi� camentos, exames e terapia nutricional em maior tempo de internação. Nos hospitais públicos, o Sistema Único de Saúde (SUS) repassa um valor diário por paciente para subsidiar os custos com nutrição enteral (NE). O objetivo do trabalho foi descrever os custos diretos com NE em pacientes hospitalizados e avaliar o percentual desses custos em relação ao repasse do SUS. Método: Estudo transversal e descritivo desenvolvido no Setor de Terapia Nutricional de um hospital público. Os custos diretos foram quantificados de acordo com consumo e custo diário de fórmulas enterais, frascos e equipos, número de pacientes por dia em uso de nutrição enteral (NE): por sonda e por suplementação nutricional oral (SNO). Os valores obtidos foram utilizados para avaliar o percentual de cobertura do valor padrão repassado pelo SUS. Resultados: No período avaliado, foram quantificadas 2066 solicitações de NE para pacientes (69,4% com NE por sonda e 30,6% com SNO). O custo médio diário por paciente em uso de NE por sonda foi de R$ 23,89 (60,0% referente à fórmula, 30,2% ao equipo, 7,7% ao frasco e 2,1% ao módulo proteico) e em uso de SNO foi de R$ 6,17 (95,7% referente à fórmula, 3,3% do frasco e 1,0% do módulo proteico). Isso representou uma cobertura do valor repassado pelo SUS de, respectivamente, 79,6% e 20,2%. Na NE por sonda, os custos estimados diários com fórmulas foram: semielementares (R$ 22,65), especializadas (R$ 19,58), hipercalórica/hiperproteica (R$ 13,13) e normocalórica/hiperproteica (R$ 10,26). Na SNO, foram de hipercalóricos/hiperproteicos (R$ 6,12), semielementares (R$ 5,80), especializados (R$ 5,43) e normocalóricos/hiperproteicos (R$ 3,51). Conclusões: Observa-se no estudo que o valor repassado pelo SUS com terapia nutricional enteral provavelmente se mostra insuficiente, principalmente para cobrir os custos com NE por sonda.

Japanese physicians' attitudes towards enteral nutrition treatment for pediatric patients with Crohn's disease: a questionnaire survey

BACKGROUND/AIMS: Enteral nutrition (EN) is recommended for the treatment of pediatric Crohn's disease (CD) in Japan. However, the indications and treatment protocols for EN vary among hospitals. In the present study, we aimed to determine how EN was administered to pediatric patients and whether physicians followed treatment guidelines in their practices. METHODS: Two types of questionnaires were administered to 32 physicians who were involved in the treatment of pediatric CD. The consensus questionnaire evaluated the physicians' attitudes towards EN, whereas the efficacy questionnaire collected data on patients with CD, aged <17 years, who had undergone induction therapy between 2006 and 2011. RESULTS: A total of 23 physicians responded to the questionnaires. The results of the consensus questionnaire indicated that 82% and 59% of study participants recommended EN treatment for all newly diagnosed pediatric patients with CD and all relapsed patients, respectively. Exclusive EN (EEN) and elemental formula were recommended by 84% and 85% of physicians, respectively. The efficacy questionnaire revealed that 57 of the 58 patients received EN. Elemental formula was used in 39 of 40 patients who were treated with EEN. Of these 40 patients, 27 were treated with EEN alone; of these, 22 (81%) achieved remission without any other treatment. The mean duration of EEN was 15.9 days. CONCLUSIONS: EN is widely recommended by physicians treating pediatric CD in Japan. In contrast to Western countries, clinicians used elemental formula more often and with a shorter EEN treatment duration.

Desarrollo y evaluación de la bebida instantánea lactovisoy / Development and evaluation of the lactovisoy instant drink

La escasez de leche en Venezuela requiere la búsqueda de nuevas fórmulas que puedan sustituir en parte su deficiencia. Debido a esto se elaboró una bebida de valor nutritivo similar al de la leche pero de menor costo. En este trabajo se presenta su desarrollo; para ello se estudiaron 10 fórmulas a base de leche descremada y completa, harina de arroz y soya. Otros ingredientes fueron azúcar, grasa vegetal, vitaminas, minerales y saborizantes. Se seleccionaron 4 fórmulas y se les sometió a un análisis proximal, evaluación sensorial y nutricional. Se probaron varios procesos de extrusión, doble tambor y mezcla en seco. Se le determinó la Relación de Eficiencia Protéica (PER) y la Digestibilidad Aparente (DA), presentando valores de 2,3 a 3,1 y 85 - 94% respectivamente. La aceptabilidad del producto se probó con 5.000 niños entre los 7 y 14 años, y resultó de un 95% de aceptación. La factibilidad económica demostró que se podía fabricar a un precio inferior al de la leche dependiendo del proceso y envase. Un vaso de 200 ml del producto reconstituido al 25% con un aporte de 8 g de proteína y 195 calorías, representa una alternativa para el programa del vaso de leche escolar y para otros programas institucionales(AU)

There is a need to develop new milk substitutes in Venezuela; thus, a cheaper beverage of similar nutritive value as milk was developed. Ten different formulas, based on skimmed milk, rice and soya flour were studied; other ingredients used included sugar, vegetable oil, vitamins, minerals and flavoring. Four of these formulas were selected, chemically analyzed, and evaluated nutritionally and organoleptically. Various technological processes were applied: extrusion, drum drying, spray drying and dry mix method. Protein Efficiency Ratio (PER), and Apparent Digestibility (AD) value were 2,3 to 3,1 and 85 to 94% respectively. Product acceptability was tested on 5.000 children 7-14 years old; 95% acceptability ratio was observed. An economic feasibility study indicated a possibility of industrialization at a lower price than whole milk which varied depending on the process and the packing used. A 25% reconstituted product (200 mL) provides 8 g protein and 195 kcal, and represents a viable alternative for the "glass of milk" school program and for other institutional nutrition-intervention programs that the goverment could implement(AU)

Qualidade nutricional e microbiológica de dietas enterais artesanais padronizadas preparadas nas residências de pacientes em terapia nutricional domiciliar / Nutritional and microbiological quality of standardized homemade enteral diets for patients in home nutritional therapy

OBJETIVO: Avaliar as propriedades físico-químicas, microbiológicas e nutricionais de dietas enterais artesanais padronizadas preparadas nos domicílios de pacientes em terapia nutricional domiciliar. MÉTODOS: Foram desenvolvidas duas formulações de dietas enterais (F1=1,2kcal/mL e F2=1,5kcal/mL), elaboradas com maltodextrina (155/155g), concentrado proteico de soro de leite (30/15g) e óleos vegetais (30/60g) dissolvidos em água (q.s.p.1000mL). Os cuidadores receberam os ingredientes e as medidas padrão e foram orientados quanto ao preparo e às boas práticas de manipulação. O estudo teve duração de quatro meses, e amostras das dietas preparadas nos domicílios de 33 pacientes foram coletadas e analisadas no início e no final deste período. As amostras foram avaliadas quanto à sua adequação percentual em relação aos valores prescritos de macronutrientes e energia, bem como aos padrões microbiológicos estabelecidos pela legislação vigente. RESULTADOS: As dietas formuladas (Formulação 1/Formulação 2) apresentaram os seguintes teores de macronutrientes, energia e osmolalidade: água - 73,5/70,0%; proteína - 4,4/6,0%; lipídeo - 4,3/6,6%; carboidrato - 16,9/16,4%; energia - 120/150kcal/100mL; osmolalidade - 440/450mOsm/kg.H2O. As variações nas adequações percentuais das amostras domiciliares foram menores que 20,0% tanto na primeira quanto na última amostragem. As proporções de amostras em desacordo com os padrões legais foram significantemente menores nas amostras finais, 24,0% e 36,0% para bactérias mesófilas e coliformes, respectivamente. CONCLUSÃO: O preparo das dietas nos domicílios apresentou boa reprodutibilidade; no entanto, a qualidade microbiológica ainda permanece uma questão preocupante, exigindo uma atuação cuidadosa do profissional de saúde nos domicílios.

OBJECTIVE: This study assessed the physical, chemical, microbiological and nutritional properties of standardized enteral diets prepared at the homes of patients receiving nutritional therapy. METHODS: Two enteral diet formulations were developed (F1=1.2kcal/mL and F2=1.5kcal/mL) containing maltodextrin (155/155g), whey protein concentrate (30/15g) and vegetable oils (30/60g) dissolved in water (q.s.p.1000mL). The ingredients and measuring devices were given to the caregivers, along with preparation instructions and advice on good handling practices. The study lasted four months and the diets prepared at the homes of 33 patients were collected at baseline and endline for analysis. The samples were analyzed to determine the compliance of their macronutrient and energy contents with the prescription and their microbiological contents with the legislation. RESULTS: The study diets (Formulation 1/Formulation 2) contained the following macronutrient and energy contents and osmolality: water - 73.5/70.0%; protein - 4.4/6.0%; lipids - 4.3/6.6%; carbohydrate - 16.9/16.4%; energy - 120/150kcal/100mL; osmolality - 440/450mOsm/kg.H2O. The percent adequacy of the homemade diets did not vary by more than 20.0% at baseline or end of study. The percentages of samples that did not meet the legal standards were significantly lower at the end of the study: 24.0% and 36.0% for mesophilic bacteria and coliforms, respectively. CONCLUSION: Homemade diets presented good reproducibility but their microbiological quality remains a matter of concern, indicating that health professionals must be careful when working at home.

Prescriçäo e uso de formulados para nutriçäo enteral pelos serviços de nutriçäo hospitalares do município de Campinas (SP) / Prescription and use of formulae for enteral nutrition by the nutrition services of the hospitals in the city of Campinas-São Paulo, Brazil

A nutrição enteral como forma de suporte nutricional é um importante recurso na prática terapêutica, respondendo de forma satisfatória aos casos de limitação à ingestão de alimentos por via oral. Contudo, não existem dados locais sobre a utilização de formulados industrializados ou artesanais pelos Serviços de Nutrição. A fim de avaliar a utilização de cada um dos tipos de formulados, bem como identificar o profissional responsável pela prescrição dos mesmos, procedeu-se a um leventamento nos hospitais de Campinas,SP, por meio de questionários. Os resultados mostram que o emprego da nutrição enteral é prática de rotina nos Serviços, e que não há diferença significativa entre a utilização de formulados industrializadas ou artesanais; mostram também que o médico é o profissional responsável pela prescrição da dieta na maior parte dos Serviços

Tube feeding is a recognized means, for dietary management of a disease, successfully surpassing the limits of patients with impaired feeding. Nevertheless, there is no local data about utilization of industrialized or domestic formulae by the Hospital Nutrition Services. In order to evaluate the utilization of both industrialized and the domestic formulae, as well as the health professional involved with diet prescription, all hospitals located in the city of Campinas, São Paulo, Brazil were interviewed. Results show that enteral nutrition is a routine for most institutions, and there is no significant deference between the use of industrialized or domestic formulae. In Campinas, the physician is responsible for the diet prescription, despite of the presence of a dietitian in the staff
