Effect of Artificial Diet on Immature Stage of the Great Eggfly, Hypolimnas bolina (Lepidoptera: Nymphalidae).

<b>Background and Objective:</b> One of the Nymphalidae butterfly species found in West Sumatra in <i>Hypolimnas bolina</i>. Currently, research on the artificial diet for the Nymphalidae butterfly is relatively rare in Padang, West Sumatra. The objectives of this study were to analyze the preferences of <i>H. bolina</i> larvae, duration of the immature stage and mortality of <i>H. bolina</i> in artificial diet treatment. <b>Materials and Methods:</b> Some biological aspects of <i>H. bolina</i> in corresponding to artificial diet and its effect were investigated in the laboratory. <b>Results:</b> The result showed that there was no significant difference in the frequency of visits of the larvae in the two diet treatments namely natural (<i>Laportea interrupta</i> leaves) and artificial diets (Sig = 0.289, p>0.05) but the duration of the visit of <i>H. bolina</i> larvae was significantly different (Sig = 0.000, p<0.05). The visit duration of the immature stage of <i>H. bolina </i>was significantly different, except the prepupa and pupal stage. There was no mortality of instar larvae and prepupa stage observed in both of the two-diet treatments. However, the mortality of pupae in an artificial diet was 4%. Of the total of 24 individual larvae fed with artificial diet, all of them successfully emerged, consisted of 12 males and 12 females but there was one male with abnormal wings. The average living period in the artificial diet of imago was 14.82 days for males and 16.77 days for a female. The average larval weight was no significant difference (Sig = 0.981, p>0.05) but the average pupal weight of the natural diet was slightly higher than the artificial diet. <b>Conclusion:</b> The formulation of an artificial diet is suitable for <i>H. bolina</i> larvae based on the results of immature mortality and adult emergences. Therefore, the formulation of an artificial diet is suitable for <i>H. bolina</i> with its composition almost similar to <i>L. interrupta</i> leaves (natural diet).

Semi-elemental versus polymeric formula for enteral nutrition in brain-injured critically ill patients: a randomized trial.

BACKGROUND: The properties of semi-elemental enteral nutrition might theoretically improve gastrointestinal tolerance in brain-injured patients, known to suffer gastroparesis. The purpose of this study was to compare the efficacy and tolerance of a semi-elemental versus a polymeric formula for enteral nutrition (EN) in brain-injured critically ill patients. METHODS: Prospective, randomized study including brain-injured adult patients [Glasgow Coma Scale (GCS) ≤ 8] with an expected duration of mechanical ventilation > 48 h. INTERVENTION: an enteral semi-elemental (SE group) or polymeric (P group) formula. EN was started within 36 h after admission to the intensive care unit and was delivered according to a standardized nurse-driven protocol. The primary endpoint was the percentage of patients who received both 60% of the daily energy goal at 3 days and 100% of the daily energy goal at 5 days after inclusion. Tolerance of EN was assessed by the rate of gastroparesis, vomiting and diarrhea. RESULTS: Respectively, 100 and 95 patients were analyzed in the SE and P groups: Age (57[44-65] versus 55[40-65] years) and GCS (6[3-7] versus 5[3-7]) did not differ between groups. The percentage of patients achieving the primary endpoint was similar (46% and 48%, respectively; relative risk (RR) [95% confidence interval (CI)] = 1.05 (0.78-1.42); p = 0.73). The mean daily energy intake was, respectively, 20.2 ± 6.3 versus 21.0 ± 6.5 kcal/kg/day (p = 0.42). Protein intakes were 1.3 ± 0.4 versus 1.1 ± 0.3 g/kg/day (p < 0.0001). Respectively, 18% versus 12% patients presented gastroparesis (p = 0.21), and 16% versus 8% patients suffered from diarrhea (p = 0.11). No patient presented vomiting in either group. CONCLUSION: Semi-elemental compared to polymeric formula did not improve daily energy intake or gastrointestinal tolerance of enteral nutrition.

Design, quality, safety and efficacy of extensively hydrolyzed formula for management of cow's milk protein allergy: What are the challenges?

Cow's milk protein allergy (CMPA) is one of the most common food allergies in infancy. Clinical food allergy guidelines recommend an extensively hydrolyzed formula (EHF) as the first-line treatment in nonbreastfed infants with CMPA. Designing and commercializing EHF poses both technical and regulatory challenges. Each manufacturing step, from sourcing of raw materials to release of the final product, needs to be managed in accordance with comprehensive quality systems. To avoid cross-contamination via externally sourced ingredients, suppliers should be carefully selected based on quality requirements. Strict zoning of the manufacturing areas according to contamination risk and air flow control are effective strategies to prevent accidental allergen contamination. Furthermore, dedicated manufacturing lines for hypoallergenic products are used to prevent potential cross-contamination from other products produced on the same line. The enzymatic hydrolysis, heat treatment and ultrafiltration used are specific to each manufacturer. Consequently, EHF are a heterogenous group of products with differences in the molecular weight profile of peptides, content of residual immunogenic cow's milk allergens, and residual in-vitro allergenicity. These differences are likely to affect clinical efficacy and safety. As not all commercialized EHF products have undergone formal testing in the laboratory and clinical trials, there is a need to develop guidelines for minimum technical and regulatory requirements for EHF products, including validated assays for ongoing quality control. Clinical trials assessing new EHF products for their hypoallergenicity and ability to support normal growth remain the definitive proof of efficacy and safety in infants and young children with CMPA.

Alimentos para usos médicos especiales en la Unión Europea: una actualización legislativa incompleta / Foods for special medical purposes in the European Union: an incomplete legislative update

Este artículo analiza el desarrollo, desde 1989 hasta 2019, de la legislación de la Unión Europea sobre los alimentos para usos médicos especiales dirigidos a pacientes y examina cómo desde 1997 los organismos científicos competentes de la Unión Europea y de los Estados Unidos de América han establecido valores de referencia de la dieta, así como niveles de ingesta superior tolerable para vitaminas y minerales basados en su seguridad. La actualización, mediante el Reglamento (UE) 2016/128, de la legislación de la Unión Europea de esta categoría de alimentos parece adecuada en el caso de los lactantes. Sin embargo, para los pacientes mayores de un año, los mínimos y máximos de vitaminas y minerales por 100 kcal de la Directiva 1999/21/CE no fueron modificados en este Reglamento, ignorando así los valores de referencia de la dieta y los niveles de ingesta superior tolerable del periodo 1997-2015, establecidos ambos por los citados organismos científicos

This article analyses, from 1989 until 2019, the development of the European Union legislation on food for special medical purposes, aimed at patients, and examines how from 1997 the competent scientific bodies of the European Union and the United States of America have established dietary reference values, as well as tolerable upper intake levels for vitamins and minerals based on their safety. The update, through the Regulation (EU) 2016/128, of the European Union legislation on this food category seems appropriate in the case of infants. However, for patients older than one year, the minimums and maximums of vitamins and minerals per 100 kcal from the Directive 1999/21/EC were not modified in this Regulation, thus ignoring the dietary reference values and the tolerable upper intake levels from the period 1997-2015, both established by the aforementioned scientific bodies

Achieving Protein Targets in the ICU Using a Specialized High-Protein Enteral Formula: A Quality Improvement Project.

BACKGROUND: To meet protein needs in critical illness (CI), guidelines suggest ≥1.2-2.5 g protein/kg/d; however, most intensive care unit (ICU) patients receive ≤0.7 g/kg/d. Higher protein enteral nutrition (EN) formulas may be part of the solution to provide prescribed protein. Our objective was to demonstrate that an EN formula with 37% protein can deliver ≥80% of prescribed protein, without overfeeding calories within the first 5 days of feeding and to describe ICU clinicians' experience. METHODS: This quality improvement (QI) project included patients requiring exclusive EN for up to 5 days from 6 Canadian ICUs. Rationale for choosing formula, patient's BMI (kg/m2 ), nutrition targets, daily protein and energy delivered, feeding interruptions, and general tolerance were recorded. RESULTS: Forty-four of 49 patients received the formula ≥2 days. Average protein prescribed was 137.5 g/d (82.5-200) or 1.9 g/kg/d (1.5-2.5). Average protein delivered was 116.9 g/d (33.5-180) or 1.6 g/kg/d (0.4-2.4). Seventy-five percent to 83% of patients received ≥80% prescribed protein on days 2-5. Average energy prescribed was 1638.6 kcal/d (990-2500) or 17.8 kcal/kg (11-26). Average energy delivered was 1523.9 kcal/d (693.0-2557.5) or 17.3 kcal/kg/d (1.35-64.7). The formula was well tolerated with no gastrointestinal symptoms reported in 38 (86%) patients. The most common reasons to prescribe the formula were obesity and use of fat-based medications. CONCLUSIONS: We demonstrated in a QI study that a high-protein EN formula was tolerated in a small, heterogeneous group of ICU patients and effective in meeting protein targets without overfeeding.

Feeding patterns and growth trajectories in breast-fed and formula-fed infants during the introduction of complementary food / Patrones de alimentación y trayectorias de crecimiento en niños con lactancia materna y con leche de fórmula durante la introducción de la alimentación complementaria

Introduction: several investigations have identified breastfeeding as a protective factor for rapid infant weight gain and childhood obesity while other studies have found that this protective effect could be the result of confounding factors. Objectives: to assess the associations between lactation practices (breast-fed vs formula-fed infants) during the introduction of complementary food period, as well as the following: a) patterns of food intake; and b) trajectories of growth at six, nine and 12 months (z-score of weight, height and body mass index [BMI] and changes in these z-scores from six to 12 months). Methods: two hundred and three infants randomly selected from Spanish Primary Health Centres were measured. Parents recorded all infant's food consumption for three days (g/day). Linear regression models were applied. Results: breast-fed infants had a lower intake of cereals, fruit baby food, vegetables with meat/fish and a total intake of food compared to formula-fed infants at nine months of age. After adjusting for sex, parental education and total food intake, breastfed children continued to have lower intake of cereals (-5.82, 95% CI: -9.22, -2.43), and lower total food intake (-301.23, 95% CI: -348.50, -253.96). Breast-fed infants had a lower change in z-score of weight, height and BMI from six to 12 months of age and these differences remained when adjusting for all confounders. Conclusions: formula-fed infants during the complementary feeding period have a higher food intake and show higher rates of rapid infant weight gain compared to breast-fed infants. These differences in growth trajectories depending on breastfeeding maintenance and food intake during early life must be considered in adiposity risk evaluation

Introducción: varios estudios han identificado la lactancia materna como un factor protector frente a la ganancia rápida de peso y la obesidad infantil, mientras que otros estudios han encontrado que este efecto protector podría ser el resultado de la interferencia de factores de confusión. Objetivos: evaluar las asociaciones entre el tipo de lactancia (leche materna versus lactantes alimentados con fórmula) durante la introducción de la alimentación complementaria, así como: a) los patrones de ingesta de alimentos; y b) las trayectorias de crecimiento a los seis, nueve y 12 meses (z-score de peso, estatura e índice de masa corporal (IMC) y variaciones en estos z-score entre los seis y los 12 meses. Métodos: se midieron 203 neonatos seleccionados en centros de salud primaria españoles. Los padres registraron el consumo de alimentos de todos los bebés durante tres días (g/día). Se aplicaron modelos de regresión lineal. Resultados: los bebés alimentados con leche materna tuvieron una menor ingesta de cereales, alimentos para bebés a base de frutas, verduras con carne/pescado, así como una menor ingesta total de alimentos en comparación con los bebés alimentados con fórmula a los nueve meses de edad. Después de realizar el ajuste por sexo, educación de los padres y consumo total de alimentos, los niños alimentados con leche materna continuaron teniendo una menor ingesta de cereales (-5,82, IC 95%: -9,22, -2,43) y una ingesta total de alimentos más baja (-301,23, IC 95%: -348,50, -253,96). Los bebés alimentados al pecho tuvieron un menor incremento en la puntuación z-score de peso, talla e IMC entre los seis y los 12 meses de edad y estas diferencias se mantuvieron cuando se ajustaron para todos los factores de confusión. Conclusiones: los lactantes alimentados con fórmula durante el periodo de alimentación complementaria tienen una mayor ingesta de alimentos y muestran tasas más altas de ganancia de peso en comparación con los lactantes alimentados con leche materna. Estas diferencias en las trayectorias de crecimiento en función del mantenimiento de la lactancia materna y la ingesta de alimentos durante los primeros años de vida deben considerarse en la evaluación del riesgo de adiposidad

[Hospital feeding process]. / Proceso de alimentación hospitalaria.

INTRODUCTION: The Management Working Group of SENPE has among its objectives the development of evaluation processes in Clinical Nutrition. Previously, the document entitled "Process of nutritional care: self-evaluation guide" was prepared as a tool designed to help assess the quality of nutritional therapy in hospitalized patients, mainly from the perspective of artificial nutrition. Now a complementary text of the previous one is presented, that describes the process by which hospitalized patients are fed. We have divided the hospital feeding process into six sections, for which a general description is made and quality indicators are proposed. We hope that this work will serve to improve the quality of hospital food and to help hospital food professionals to make their work more satisfactory and effective.

INTRODUCCIÓN: El Grupo de Trabajo de Gestión de SENPE tiene entre sus objetivos el desarrollo de procesos de evaluación en Nutrición Clínica. Con anterioridad se elaboró el documento denominado "Proceso de atención nutricional: guía de autoevaluación", como una herramienta concebida para ayudar a evaluar la calidad de la terapia nutricional en pacientes hospitalizados, fundamentalmente desde la perspectiva de la nutrición artificial. Ahora se presenta un texto complementario del anterior, en el que se describe el proceso por el que alimenta a los pacientes hospitalizados. Hemos dividido el proceso de alimentación hospitalaria en seis secciones, para las que se hace una descripción general y se proponen indicadores de calidad para su evaluación. Confiamos en que este trabajo sirva para mejorar la calidad de las dietas de los hospitales y para ayudar a los profesionales de la alimentación de los hospitales a hacer su labor más satisfactoria y efectiva.

Safety and efficacy of volume-based feeding in critically ill, mechanically ventilated adults using the 'Protein & Energy Requirements Fed for Every Critically ill patient every Time' (PERFECT) protocol: a before-and-after study.

BACKGROUND: Underfeeding in critical illness is common and associated with poor outcomes. According to large prospective hospital studies, volume-based feeding (VBF) safely and effectively improves energy and protein delivery to critically ill patients compared to traditional rate-based feeding (RBF) and might improve patient outcomes. A before-and-after study was designed to evaluate the safety, efficacy and clinical outcomes associated with VBF compared to RBF in a single intensive care unit (ICU). METHODS: The sample included consecutively admitted critically ill adults, mechanically ventilated for at least 72 h and fed enterally for a minimum of 48 h. The first cohort (n = 46) was fed using RBF, the second (n = 46) using VBF, and observed for 7 days, or until extubation or death. Statistical comparison of percentage feed volume, energy and protein delivered, plus indices of feed intolerance, were the primary outcomes of interest. Secondary observations included ventilation period, mortality, and length of ICU stay (LOICUS). RESULTS: Groups were comparable in baseline clinical and demographic characteristics and nutrition practices. Volume delivered to the VBF group increased significantly by 11.2% (p ≤ 0.001), energy by 13.4% (p ≤ 0.001) and protein by 8.4% (p = 0.02), compared to the RBF group. In the VBF group, patients meeting > 90% of energy requirements increased significantly from 47.8 to 84.8% (p ≤ 0.001); those meeting > 90% of protein requirements changed from 56.5 to 73.9% (p = 0.134). VBF did not increase symptoms of feed intolerance. Adjusted binomial logistic regression found each additional 1% of prescribed feed delivered decreased the odds of vomiting by 0.942 (5.8%), 95% CI [0.900-0.985], p = 0.010. No differences in mortality or LOICUS were identified. Kaplan-Meier found a significantly increased extubation rate in patients receiving > 90% of protein requirements compared to those meeting < 80%, (p = 0.006). Adjusted Cox regression found the daily probability of being extubated tripled in patients receiving > 90% of their protein needs compared to the group receiving < 80%, hazard ratio 3.473, p = 0.021, 95% CI [1.205-10.014]. CONCLUSION: VBF safely and effectively increased the delivery of energy and protein to critically ill patients. Increased protein delivery may improve extubation rate which has positive patient-centred and financial implications, warranting larger confirmatory trials. This investigation adds weight to the ICU literature supporting VBF, and the growing evidence which advocates for enhanced protein delivery to improve patient outcomes.

Nutrition process improvements for adult inpatients with inborn errors of metabolism using the i-PARIHS framework.

AIM: This project aimed to implement consensus recommendations and innovations that improve dietetic services to promote timely referral to optimise nutritional management for adult inpatients with inborn errors of metabolism (IEM). METHODS: The i-PARIHS framework was used to identify service gaps, implement innovations and evaluate the innovations within this single-site study. The constructs of this framework are: (i) review of the evidence; (ii) recognising patients and staff knowledge and attitudes; (iii) acknowledging the local context; and (iv) the facilitators role. This included a literature review and metabolic centre service comparisons to investigate dietetic referral and foodservice processes to inform the innovation. A 12-month chart audit (6 months retrospective and prospective of implemented innovation, respectively) to evaluate newly established dietetic referral and IEM nutrition provision procedures was also completed. RESULTS: The innovations implemented encompassed a clinical alert triggering urgent referral, nutrition sick day plans and metabolic diet and formula prescription via an 'alert' tab in electronic records. Eleven metabolic protein-restricted diets and nine formula recipes were introduced. Prior to the innovations, only 53% (n = 19/36) of inpatients with IEM were assessed by the dietitian and received appropriate nutrition within 24 hours. Following implementation of the innovations, 100% (n = 11/11) of inpatients with IEM received timely dietetic assessment and therapeutic nutrition. CONCLUSIONS: Implementation of innovations developed using the i-PARIHS framework is effective in timely notification of the metabolic dietitian of referrals. This ensures optimal nutritional management during admissions which is required in this group of high-risk patients.

Home Blenderized Tube Feeding: A Practical Guide for Clinical Practice.

Although commercial enteral formulas have been available on the market for several decades, a cultural shift toward consuming unprocessed foods with minimally added sugar has sparked interest in the preparation of home blenderized tube feedings for enteral feeding-dependent patients. Recent surveys, however, indicate lack of clinical awareness or familiarity in the management of this method of nutrition support. This article aims to equip the gastroenterologist with a guide for initiation, monitoring, and evaluation of a blenderized tube feedings regimen, and provides insights into an opportunity for greater partnership between the gastrointestinal provider and registered dietitian.

The effect of an elemental diet on oral mucositis of esophageal cancer patients treated with DCF chemotherapy: a multi-center prospective feasibility study (EPOC study).

PURPOSE: Oral mucositis (OM) is one of the most uncomfortable adverse events experienced by cancer patients undergoing chemotherapy. Previous reports have revealed that the oral administration of an elemental diet (ED) may prevent OM. However, the incidence of OM has not been accurately determined by specialized diagnostic methods and the effects of an ED on OM remain unclear. We investigated the dose that could feasibly be administered and its effects with regard to the suppression of OM in esophageal cancer patients undergoing chemotherapy. METHODS: We performed a prospective multi-center feasibility study of the administration of an ED (160 g/day) with 2 cycles of docetaxel/cisplatin/5-FU (DCF) chemotherapy. We assessed compliance to the ED for 49 days and the incidence of OM according to the amount of the ED that was orally administered. The incidence of OM was graded by a dental specialist who was experienced in dental oncology using a central OM review system. RESULTS: Fourteen of 20 patients (70%) were able to complete the orally administered ED (160 g/day) during the course of chemotherapy. Three patients (15%) could not take the ED orally for 9, 14, and 21 days, respectively, while 1 patient (5%) took the ED orally at an average dose of 80 g/day for 35 days. The remaining 2 patients (10%) could not take the 80 g/day dose for 11 and 12 days, respectively. The incidence of grade ≥ 2 OM in the ED completion group (15.4%, 2 of 13 patients) was significantly lower than that in the non-completion group (66.7%, 4 of 6 patients) (p = 0.046). CONCLUSIONS: An ED might be a one of the test treatment to reduce the incidence of OM in esophageal cancer patients treated with DCF and should be evaluated in further randomized study. CLINICAL TRIAL: The date of submission: Dec 08th, 2017.

Blended tube feeding prevalence, efficacy, and safety: What does the literature say?

BACKGROUND AND PURPOSE: For most of human history, physicians used blended whole foods for patients who are unable to eat by mouth. However, by the 1960s and 1970s, advances in enteral nutrition resulted in the gradual displacement of blenderized tube feedings (BTFs) with commercial formulas. There are advantages and disadvantages to commercial formulas and BTFs. The purpose of this article was to review the literature for the incidence of blended tube feeding use and its safety, efficacy, and implications for clinical practice. METHODS: A search of the scientific literature in PubMed, CINAHL, Cochrane, ProQuest, and Ovid was conducted using the keywords "blenderized tube feeding" and "blended tube feeding." Articles were divided into two categories: 1) frequency of use and experiences of BTF in patients or caregivers and health care providers and 2) safety/efficacy studies. CONCLUSIONS: The literature review shows a rising interest in BTF, with more research on efficacy indicated. IMPLICATIONS FOR PRACTICE: The use of BTF is primarily patient or caregiver driven. Blenderized tube feeding requires oversight by health care providers just as commercial formulas. Health care providers should be aware of the use of BTF and the effect it can have on different patient populations regarding content, cost, safety, and efficacy in the clinical and home settings.

Visualizing the Consistency of Thickened Liquids With Simple Tools: Implications for Clinical Practice.

Purpose: Accurate texture modifications to thin liquids are a critical aspect of patients' nutritional health and well-being. This study explored the use of 3 tools (2 distance- and 1 time-measuring devices) to characterize texture-modified liquids. The objectives were to use the tools to measure modified liquids, to determine if measurements differentiated nectar and honey levels of modification, and to compare measurements with other published reports. Method: We measured the flow distance of 33 prethickened water samples in centimeters (cm) using a line spread apparatus and a Bostwick Consistometer (Christison Particle Technologies). We selected a Zahn viscosity cup to measure the stream time of each prethickened liquid in seconds. Results: The 2 distance-measuring devices (line spread and Bostwick Consistometer) showed that thinner (nectar-thick) modifications spread or flowed a farther distance in comparison to thicker (honey-like) modifications. Testing with the line spread indicated that an average spread distance of 4.5 cm differentiated nectar-thick and honey-like consistencies. A flow distance of greater than 15 cm differentiated nectar from honey consistency measured with a Bostwick Consistometer. We were not successful in using the Zahn viscosity cup to determine the stream time of modified liquids. Conclusions: Two of the tools provided objective information about levels of liquid modification, which has implications for day-to-day preparation. Measurement tools that are accurate and easy to use have the potential to provide quick and dependable feedback to verify a prescribed level of liquid modification. Further efforts are needed to standardize the application of simple measurement tools in the management of patients who consume thickened liquids.

Indigenous food ingredients for complementary food formulations to combat infant malnutrition in Benin: a review.

This paper reviews indigenous Beninese food resources as potential ingredients for complementary infant foods with the aim to develop affordable formulations for low-income households in each agro-ecological zone of the country. Potential ingredients were selected on their documented nutritional value. The selected foods encompass 347 food resources, namely 297 plant products from home gardens or collected from natural vegetation and 50 animals, either domesticated or from the wild. The compiled data reveal that the distribution of the available food resources was unbalanced between agro-ecological zones. Only a few animal ingredients are obtainable in northern Benin. Most resources are seasonal, but their availability may be extended. A high variation was observed in energy and nutrient contents. Antinutritional factors were identified in some resources, but processing techniques were reported to reduce their presence in meals. In general, ingredients from local tree foods (Adansonia digitata, Parkia biglobosa) were adequate as sources of nutrients for complementary infant foods. Based on this review, local foods for the development of complementary food formulas for Beninese infants and children may be selected for each agro-ecological zone. The approach used is exemplary for other sub-Saharan African countries in need of complementary infant foods. © 2017 Society of Chemical Industry.

Nutritional and microbiological quality of commercial and homemade blenderized whole food enteral diets for home-based enteral nutritional therapy in adults.

BACKGROUND & AIMS: Serious nutritional and contamination risks may be involved in the preparation of blenderized tube-feeding diets and in the handling of commercial diets. Their nutritional and microbiological quality in home settings is unknown. The objective of this study was to assess the nutritional and microbiological quality of commercial enteral and homemade blenderized whole foods diets intended to adult patients in home nutritional therapy. METHODS: In a cross sectional study, 66 samples of commercial (CD) and noncommercial (NCD) enteral diets were collected at the homes of patients in home enteral nutritional therapy, 33 of each type. Commercial diets were either powder (PCD; n = 13) or liquid (LCD; n = 20). The samples were analyzed in laboratory to assess their nutritional and microbiological quality. Anthropometric data of mid upper arm circumference (MUAC) and triceps skinfold (TST) thickness were obtained from the patients' medical records. RESULTS: NCD presented significantly lower values for protein, fat, fiber, carbohydrate and energy while water content was significantly higher. PCD and LCD did not show any statistically significant differences between them. In the NCD, the values measured for macronutrients and energy corresponded to less than 50% of the prescribed values (except for fat). In CD, protein value was about 20% more than the prescribed value; fat and energy values corresponded to approximately 100% of the prescription, while carbohydrate corresponded to 92%. Regardless the type of the diet, prevalence of undernutrition was high in both groups though patients of the NCD presented a higher percentage. Samples of NCD complied significantly less with the microbiological standards; only 6.0% complied with the standard for coliform bacteria. Escherichia coli was detected in 10, 2, and 2 samples of NCD, PCD and LCD, respectively. CONCLUSIONS: Homemade blenderized enteral diets showed low values of energy and macronutrients, delivered less than 50% of the prescribed values and had high levels of bacterial contamination.

Objective: To communicate HPN data obtained from the HPN registry of the NADYA-SENPE group (www.nadya-senpe.com) for the year 2016. Material and methods: Descriptive analysis of the data collected from adult and pediatric patients with HPN in the NADYA-SENPE group registry from January 1st, 2016 to December 31 st, 2016. Results: There were 286 patients from 42 Spanish hospitals (54.2% women), 34 children and 252 adults, with 294 episodes, which represent a prevalence rate of 6.16 patients / million inhabitants / year 2016. The most frequent diagnosis in adults was «palliative cancer» (25.8%), followed by «others». In children it was «motility alterations» with 6 cases (17.6%), Hirschsprung's disease and necrotising enterocolitis, both with 5 children (14.7%). The first indication was short bowel syndrome in both children (64.7%) and adults (37.3%), followed by intestinal obstruction in 28.6% adults and 14.7% in children. The most frequently used type of catheter was tunnelled in both children (70.6%) and adults (37.9%). The most frequent complication in adults was infection related to the catheter, which presented a rate of 0.48 infections / 1,000 days of NPD. During this period, 71 episodes ended in adults and the main cause was death (57.7%) followed by resuming the oral route (31%). Conclusions: There is a progressive increase of centers and professional collaborators in the registry who report patients receiving parenteral nutrition at home. The main indications of HPN and the motive for ending have remained stable (AU)

Development of a simple and objective evaluation method for thickened liquids using funnels.

Some patients with dysphagia are prone to aspiration of low-viscosity liquids. Thickened liquids are often used in attempts to prevent aspiration. The patients should be given thickened liquids with suitable thickness, and the thickness should be constant at all time. While rotational and cone-and-plate viscometers are used for the evaluation of thickened liquids, they are high-precision and expensive equipment. To control the thickness of liquids, a simple and objective evaluation method is thus necessary. We developed a method to evaluate thickened liquids using funnels, and verified the appropriateness of this method. We measured the outflow times of five thickened liquids through funnels. One of the thickened liquids was a commercially available nutritional supplement, another was made with a thickening agent that contained guar gum, and all others were made with a thickening agent that contained xanthan gum. Four funnels with different stem sizes were tested. We found that the outflow time of thickened liquids through a funnel depended on their viscosities at a shear rate between 10 and 50 s-1 , when the average inner diameter of the stem was in the range of 5.3-9.0 mm, and the volume of the liquid poured into the funnel was 30 mL. The correlation coefficient between the value of the sensory evaluation and the outflow time of the funnel with an average stem ID of 5.3 mm was 0.946. Therefore, this method may be useful in hospital and nursing home kitchens for evaluating thickened liquids. PRACTICAL APPLICATIONS: The findings of this study will help develop a new method for the evaluation of thickened liquids. Funnels made from polypropylene, which are inexpensive and light, were used in this method. The process for measuring the outflow time of thickened liquids through a funnel is simple, and we can obtain quantitative data that are objective. Even though line spread test (LST) is well known as a simple measurement method, nutritional supplements and liquids thickened using a thickening agent containing guar gum have not been evaluated accurately. The funnel method was found to have a stronger correlation with sensory evaluation compared to LST. This method is useful in hospital and nursing home kitchens for evaluating thickened liquids.

Enhanced Protein-Energy Provision via the Enteral Route in Critically Ill Patients (PEP uP Protocol): A Review of Evidence.

Nutrition support is an integral part of care among critically ill patients. However, critically ill patients are commonly underfed, leading to consequences such as increased length of hospital and intensive care unit stay, time on mechanical ventilation, infectious complications, and mortality. Nevertheless, the prevalence of underfeeding has not resolved since the first description of this problem more than 15 years ago. This may be due to the traditional conservative feeding approaches. A novel feeding protocol (the Enhanced Protein-Energy Provision via the Enteral Route Feeding Protocol in Critically Ill Patients [PEP uP] protocol) was proposed and proven to improve feeding adequacy significantly. However, some of the components in the protocol are controversial and subject to debate. This article is a review of the supporting evidences and some of the controversy associated with each component of the PEP uP protocol.
