Effect of Consumption of Sphenostylis stenocarpa Seed-formulated Diet on Oxidative Stress Biomarkers of Dexamethasone-treated Pregnant Rats

Aim: The present study tends to examine the effect of consumption of Sphenostylis stenocarpa-formulated diet on oxidative stress biomarkers of dexamethasone-treated pregnant rats. Methodology: Sphenostylis stenocarpa was obtained locally from a market in Ado Ekiti. They were ground into powder and used to make feed for laboratory animals. Fifteen pregnant female rats were divided into three groups of five. Animals in group A were only fed standard animal feed. This served as the control group. Those in group B were exposed to Sphenostylis stenocarpa-formulated diet + 0.3 mg/kg body weight of dexamethasone, while those in group C were exposed to Sphenostylis stenocarpa-formulated diet. At the end of the eight days treatment, animals were sacrificed and blood sample, liver and kidney were collected. Results: The results revealed that treatment of animals with dexamethasone significantly increased (P<0.05) the activities of SOD and CAT and the concentration of MDA but decreased the concentration of GSH in plasma, liver homogenate and kidney homogenate respectively when compared with those in animals in the control group as well as those fed with S. stenocarpa-formulated diet only. The result further showed that feeding of animals with S. stenocarpa-formulated diet only had no significant effect on oxidative stress biomarkers investigated when compared with those in the control group. Conclusion: It can be concluded that exposure of animals to dexamethasone induced oxidative stress in animals while S. stenocarpa-formulated diet possesses the potential to alleviate the effect of oxidative stress generation.

Aceptabilidad de los almuerzos del Programa de Alimentación Escolar y estimaciones de pérdidas económicas asociadas en la comuna de Coquimbo, Chile

RESUMEN Una nutrición adecuada es fundamental para el crecimiento y desarrollo óptimo de la infancia. En Chile, el Programa de Alimentación Escolar tiene como propósito disminuir la brecha asociada con el acceso a la cantidad y calidad de los alimentos en la población de estudiantes vulnerables. El objetivo de este estudio fue determinar el grado de aceptabilidad de los almuerzos que el Programa ofrece a los estudiantes y sus pérdidas económicas asociadas. Se realizó un estudio descriptivo transversal en 528 estudiantes primarios y secundarios de 5 colegios públicos de la comuna de Coquimbo, quienes evaluaron 6 almuerzos mediante la escala sensorial hedónica de 9 puntos, encuesta de características organolépticas, test de ordenación y determinación de porcentaje de ingesta para establecer pérdidas económicas. Se realizó muestreo probabilístico estratificado, ANOVA para análisis de la escala hedónica y porcentaje de ingesta, tablas de contingencia, Chi cuadrado para características organolépticas (p<0,05). Se encontró que la carne de res con fideos tuvo la mayor preferencia y las más bajas aceptaciones fueron frijoles con fideos y pastel de pescado con puré de papas (p<0,05). Las preparaciones con menor aceptabilidad representaron el 82,2% de las pérdidas económicas, principalmente frijoles. Los resultados confirman una baja ingesta de pescado y verduras, que las características de sabor por bajo contenido de sal afectan las preferencias y que existe una relación directa entre la ingesta y la pérdida económica.

ABSTRACT Adequate nutrition is a fundamental factor for optimal early childhood growth and development. In Chile, the School Nutritional Program aims to diminish the gap associated with access to the quantity and quality of food. The objective of this study was to determine the degree of acceptability of prepared lunches that are given to students by the School Nutritional Program and its association with economic losses. A descriptive cross-sectional study was carried out among 528 primary and secondary students from 5 public schools in the Coquimbo commune, who evaluated 6 lunches using the 9-point hedonic sensory scale, a survey of organoleptic characteristics, a ranking test and determination of the intake percentage to establish economic losses. Stratified probability sampling was performed, ANOVA for analysis of the hedonic scale and percentage of intake, contingency tables, Chi square tests were used for organoleptic characteristics (p<0.05). The thin sliced beef with noodles was found to have the highest preference and the lowest ranked meals were beans with noodles and fish cake with mashed potatoes (p<0.05). Preparations with lower acceptability represented 82.2% of economic losses and were mainly beans. The results confirm a low intake of fish and vegetables, that taste characteristics due to low salt content affect preferences and that there was a direct relationship between intake and economic loss.

ABSTRACT Introduction: Aflatoxin M1 (AFM1) is a toxic metabolite derived from aflatoxin B. Its ingestion in infants has been related to growth retardation, increased susceptibility to infectious diseases, reduced immunization efficiency, and cirrhosis. In Paraguay, exclusive breastfeeding is recommended up to 6 months of age, however, different brands of infant formulas targeted at this age range are marketed. Objective: To detect and quantify the presence of AFM1 in infant formulas marketed in the Metropolitan Area. Materials and Methods: Fluid (n = 18) and powder (n = 91) formulas for infants aged 0 to 12 months were purchased from pharmacies and supermarkets in the Metropolitan Area of Asunción and were analyzed using the enzyme-linked immunoaffinity assay (ELISA). Results: 9.75% (0 to 6 months) and 2% (6 to 12 months) of the powdered milk formulas and 100% of the fluid formulas were positive for AFM1. The median content of AFM1 in powder formulas was 1820 ng/kg and 510 ng/kg in brands A and B, while in liquid formulas it was 31.8 ng/kg and 33.6 ng/kg for the two brands analyzed respectively (p = 0.0001). Conclusions: AFM1 was detected in all the liquid formulas analyzed, and in 2 and 9.7% of the powder formulas of brands A and B, respectively. The levels of AFM1 were higher in the powder formulas.

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.

Caulerpa lentillifera and Sucrose Formulated Diets as Growth Enhancer of Oyster (Crassostrea virginica)

A total of 200 of Crassostrea virginica populations of average weight range from 41.19 ± 3.42 to 47.53 ± 1.06 g were studied to determine the effect of the feed diets of Caulerpa lentillifera and sucrose as growth enhancement. Growth rates increased that range from 56.99 ± 3.16 to 61.56 ± 2.87 g for 90 days period using an artificial water tank system. Previous studies conducted that C. lentillifera contained high protein and were the most abundant component. This seaweed also contained high amounts of minerals and balanced amino acid and notably very rich in iodine. phosphorus, calcium, magnesium and copper that will contribute to oysters growth. Oysters are known to have the ability to uptake dissolved organic matter as nutrients. In the present study, the effects of culture water supplemented with sucrose were tested on oysters. Results revealed that this organic matter promotes growth to the oysters. Sugars will be metabolized into pyruvate through the glycolysis pathway and will result in the supply of energy. Therefore, supplementation of sugar to oysters may have contributed as an energy source together with the lipid and protein content from the algae diet.

Analysis of ingredients difference between Danggui Buxue Decoction and formula granule decoction based on HPLC fingerprint evaluation / 中草药

Objective: Taking Danggui Buxue Decoction (DBD) as the research object, the differences of chemical composition types and content among traditional decoction, self-made granule decoction and marketable granule decoction were compared, in order to provide scientific basis for clinical application of Chinese medicine formul granules. Methods: The fingerprint was established by HPLC. The value of the chemical composition, the content of the index components, the area of the common peak area, and the similarity of the fingerprint were evaluated, and the different dosage forms of the decoction of DBD were investigated. The effect of chemical composition on the chemical equivalence of traditional decoction and formula granules was compared. Results: The number of chromatographic peaks ranged from 15 peaks of traditional decoction to 13 (factory A), 12 (self-made), 11 (factory B), and 9 (factory C). The content of ferulic acid in formula granules was significantly different from that in traditional decoction (P formula granule decoction of factory A > self-made formula granule decoction > formula granule decoction of factory B > formula granule decoction of factory C. Content of campanulin was in order : self-made formula granule decoction > traditional decoction > formula granule decoction of factory A > formula granule decoction of factory B > formula granule decoction of factory C. The total peak area of formula granule decoction was lower than that of traditional decoction. If the traditional decoction was 1, the others (self-made and factories A, B, C) were equivalent to 0.95, 0.66, 0.40 and 0.47, respectively. Comparing with traditional decoction, self-made formula granule decoction and formula granules from factories A and B had higher similarity (0.97, 0.96, 0.98), while that from factory C was slightly lower (0.85). The main chromatographic peaks of DBD were found to be from the single herbs and no new chemical components were found. The disappearance of ingredients in formula granule Decoction was found. Conclusion: The content of index components and the number of chromatographic peaks of traditional decoction of DBD is higher than those in the formula granule decoction. There are some differences between them. This indicates that the clinical equivalence of formula granules is not consistent with the reality of decoction, so the recommended clinical equivalence of formula granules of traditional Chinese medicine should be corrected to promote rational clinical application, which can provide scientific research ideas for the unified management of the quality of formula granules of Chinese materia medica.

In vitro anti-Candida activity of Quercus infectoria gall extract-based vaginal cream and its local tissue effects in vivo

Aims@#Aqueous extract of Quercus infectoria (QI) galls has been reported to possess anti-fungal and anti-inflammatory activities. Hence, this study aimed to determine in vitro antimicrobial activity of formulated QI gall extract-based vaginal cream against Candida albicans and to evaluate the possible side effects on the cervicovaginal epithelium of healthy rats. @*Methodology and results@#Three different cream formulations containing 10%, 20%, and 30% of QI gall extract respectively were tested for their antimicrobial activity against C. albicans (ATCC 10231) by using disc diffusion test. Microbroth serial dilution method was performed in determining the minimum inhibitory concentration (MIC) and fungicidal concentration (MFC). The 30% formulated extract cream (FEC) was applied topically on the cervicovaginal surface of healthy Sprague Dawley (SD) rats and examined for local tissue effects histologically. The mean scores of inhibition zone diameter were compared by one-way ANOVA and post-hoc test using PRISM software. All extract cream formulations displayed a relatively good anti-Candida activity. The MIC values exhibited by 10%, 20%, and 30% FEC against C. albicans were 1.094 mg/mL, 0.547 mg/mL, and 0.068 mg/mL, respectively. The 10% and 20% FECs showed a significant difference (P=0.0254) in the mean of inhibition zone diameter. The lowest MFC value (0.068 mg/mL) was shown by 30% FEC. There were no abnormal changes seen at the vagina and cervical mucosa after 2 weeks application of 30% FEC. @*Conclusion, significance and impact of study@#QI gall extract formulated in the cream base has an anti-Candida activity in vitro and the present finding suggests that this herbal cream formulation is potentially useful in preventing vaginal candidiasis without causing any unwanted local side effects.

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.

Feed of Siamese fighting fish, Betta splendens, (Regan, 1910) in open pond: live and formulated diets / Alimentação do peixe-de-briga, Betta splendens (Regan, 1910) em tanque externo de cultivo: dieta natural e formulada

Abstract The growth rate and percent survival of Betta splendens when submitted to formulated diet and live food treatments are evaluated. The three different diets were used and designated as: formulated diet (basal diet); live food diet (plankton) and mixed diet (formulated diet with plankton). The live food diet contained plankton belonging to an open pond. High mortality was reported with live food (plankton) treatment whereas higher percent survival occurred with formulated diet. Highest specific growth rate, weight gain and final weight were reported in the mixed diet treatment and were significantly different (p<0.01) from those in formulated diet and live food treatments. The gut contents of B. splendens in mixed diet and live food treatments comprised, Rotifera and Bacillariophyceae species in high percentages or rather, over 78% of total organisms. Lecane sp. was the most ingested zooplankton species by B. splendens in both treatments (mixed diet and live food), with the phytoplankton species Asterionella sp. and Melosira sp. respectively in mixed diet and in live food, respectively. Results indicated that the formulated diet influenced the water parameters dissolved oxygen, total suspended solids, total dissolved solids and pH. The live food in the open pond was not enough to improve the growth rate and percent survival of B. splendens. The growth performance of B. splendens; had the best results with mixed diet which was capable of maintaining species’s survival (82%) and development in artificial conditions, benefiting the culture management of ornamental fish.

Resumo Foi avaliado o crescimento e sobrevivência de Betta splendens, quando submetidos à dieta formulada e alimento vivo. Foram utilizadas três dietas experimentais e designadas como: dieta formulada (ração); alimento vivo (plâncton) e dieta mista (ração com plâncton). O plâncton pertence ao tanque externo de cultivo. Alta mortalidade foi observada no tratamento com alimento vivo (plâncton) e a mais alta sobrevivência na dieta formulada. No tratamento com dieta mista foram observadas as maiores taxas de crescimento específico, ganho de peso e peso final, sendo significativamente diferentes (p<0,01) dos outros tratamentos. No conteúdo do trato digestório do B. splendens nos tratamentos dieta mista e alimento vivo, as espécies de Rotifera e Bacillariophyceae foram encontradas acima de 78% do total de organismos observados. Lecane sp. foi a espécie de zooplâncton mais ingerida por B. splendens em ambos os tratamentos (dieta mista e alimento vivo) e de fitoplâncton foi Asterionella sp. (dieta mista) e Melosira sp. (alimento vivo). Os resultados do presente estudo indicaram que a dieta formulada (ração) influenciou alguns parâmetros da água, como oxigênio dissolvido, sólidos totais solúveis, sólidos totais solúveis, sólidos totais suspensos e pH, e o alimento vivo não foi suficiente para incrementar o crescimento e a sobrevivência de B. splendens.

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)

Effect of enteral nutrition by a polymeric formula in patients with severe acute pancreatitis / 中华胰腺病杂志

Objective To evaluate the effect of enteral nutrition by a polymeric formula in patients with severe acute pancreatitis (SAP).Methods Fifty-eight patients with SAP were randomly divided into polymeric group (29 cases) and semi-elemental group (29 cases),and the two groups of patients were treated in accordance with the conventional SAP management protocol,nasojejunal tube was endoscopically inserted for enteral nutrition.The polymeric group received enteral nutritional suspension (TPF),and the semi-elemental group received the same quantity of VIVONEX TEN.The gastrointestinal tolerance (VAS score),incidence of diarrhea,infection,28-day mortality rate,and length of hospital stay was evaluated.Nutritional parameters were evaluated by pre-albumin,albumin,alanine aminotransferase,C reactive protein at the time of admission and one week later.Results The two groups of patients were comparable in terms of VAS score,incidence of diarrhea,infection,28-day mortality rate,and length of hospital stay (P ＞0.05).And the levels of prealbumin,albumin,alanine aminotransferase,C reactive protein after admission were not statistically significant (P ＞ 0.05).Conclusions Compared with the semi-dement formula,the price of polymeric formula is cheap,configuration is convenint,enteral nutrition is well tolerated,and it is suitable for early enteral nutrition in SAP.

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.
